Mortgage; (ii) the review by Landlord or its representatives of any plans and
specifications in connection with any restoration of any of the Leased
Properties, any Capital Addition or otherwise; (iii) the review by Landlord or
its representatives of any request by Tenant for any other approval or consent
hereunder, or any waiver of any obligation of Tenant hereunder; (iv) any
assistance provided by Landlord in connection with a permitted contest pursuant
to Paragraph 26; (v) in connection with any Default by Tenant under this Lease;
or (vi) any other request by Tenant comparable to any of the foregoing.

      (e) Late Charge; Interest. If Tenant fails to make any payment of Rent on
or before the date such payment is due and payable and such amount remains
unpaid for a period of five (5) days, such past due payment shall bear interest
at the Overdue Rate.

      (f) Payment without Abatement. No abatement, diminution or reduction of
Rent shall be allowed to Tenant or any Person claiming under Tenant, under any
circumstances or for any reason whatsoever, except to the extent herein
provided.

6. HOLDING OVER. If Tenant or any other Person shall remain in possession of one
(1) or more of the Leased Properties or any part thereof following the
expiration of the Term or earlier termination of this Lease without an agreement
in writing between Landlord and Tenant with respect thereto, the Person
remaining in possession shall be deemed to be a tenant at sufferance, and during
any such holdover, the Rent payable under this Lease by such tenant at
sufferance

                                       15
<PAGE>

shall be one hundred fifty percent (150%) of the Rent in effect immediately
prior to the expiration of the Term or earlier termination of this Lease. In no
event, however, shall such holding over be deemed or construed to be or
constitute a renewal or extension of this Lease.

7. USE OF LEASED PROPERTY; COMPLIANCE WITH LEGAL REQUIREMENTS.

      (a) Intended Use. Tenant shall use the Leased Properties as a senior
housing facility, including, without limitation, as a senior housing and/or
independent living and/or an assisted living facility and for such other uses as
may be related, incidental or necessary thereto (the "Intended Use") and for no
other purpose; provided, that in no event shall any of the Leased Properties be
used as a skilled nursing facility. Tenant shall not perform any act or follow
any practice relating to any of the Leased Properties which shall constitute a
nuisance. Subject to the terms and provisions of this Lease, Tenant shall have
the right to control the business being conducted at each of the Leased
Properties.

      (b) Compliance with Legal Requirements, Insurance Requirements, Facility
Mortgage Requirements and Other Requirements. Tenant, at its sole expense, and
subject to the right of diligent contest as provided in Paragraph 26, shall (i)
comply with all Legal Requirements, Insurance Requirements and Facility Mortgage
Requirements (provided that, with respect to any Facility Mortgage, the terms of
such Facility Mortgage comply with the requirements of Paragraph 54(b)) in
respect of the use, operation, maintenance, repair, alteration and restoration
of each of the Leased Properties, including, without limitation, all zoning
classifications of any lawful Government Agencies or other public or private
regulatory authority (including insurance underwriters or ratings bureaus)
having jurisdiction over any of the Leased Properties, (ii) comply in all
material respects with all Other Requirements and (iii) procure, maintain and
comply in all material respects with all Permits and Licenses, and for the
proper operation and maintenance of each of the Leased Properties or any part
thereof, including, without limitation, any Capital Additions, except, in the
case of (i), (ii) or (iii) above, where failure to comply will not have a
material adverse effect on Tenant or Tenant's ability to operate the Leased
Properties for their Intended Use. Upon Tenant's written request, Landlord shall
cooperate with Tenant's reasonable requests and at Tenant's sole cost and
expense, to the extent Landlord's involvement is required for Tenant to comply
with this Paragraph 7(b).

      (c) Compliance with Third Party Payor Program Requirements. Tenant shall,
at its sole cost and expense, make (i) whatever improvements (capital or
ordinary) as are required to conform each of the Leased Properties in all
material respects to such standards, if any, as may, from time to time, be
required by any applicable Third Party Payor Programs to the extent Tenant
elects to be and remains a participant in such Third Party Payor Programs (it
being acknowledged that the initial election to participate and to continue to
participate in such Third Party Payor Programs is at the sole and absolute
discretion of Tenant), or (ii) capital improvements required by any other
Government Agency having jurisdiction over the applicable Leased Property as a
condition of the continued operation of such Leased Property for its Intended
Use, except, in the case of (i) or (ii) above, where the failure to comply will
not have a material adverse effect on Tenant or Tenant's ability to operate the
Leased Properties for their Intended Use.

                                       16
<PAGE>

      (d) Landlord to Grant Easements, Etc. Landlord shall from time to time, at
the request of Tenant and at Tenant's sole cost and expense, with respect to
each applicable Leased Property (i) grant easements and other rights in the
nature of easements with respect to the applicable Leased Property to third
parties; (ii) release existing easements or other rights in the nature of
easements which are for the benefit of the applicable Leased Property; (iii)
dedicate or transfer unimproved portions of the applicable Leased Property for
road, highway or other public purposes; (iv) execute petitions to have the
applicable Leased Property annexed to any municipal corporation or utility
district; (v) execute amendments to any covenants and restrictions affecting the
applicable Leased Property; and (vi) execute and deliver to any Person any
instrument appropriate to confirm or effect such grants, release, dedications,
transfer, petitions and amendments (to the extent of its interests in the
applicable Leased Property); provided, however, that Landlord shall have first
reasonably determined in good faith that such grant, release, dedication,
transfer, petition or amendment is not detrimental in any material respect to
the operation of the applicable Leased Property for its Intended Use, does not
materially reduce the value of the applicable Leased Property and, to the extent
required by the Facility Mortgage, if any, is acceptable to the Facility
Mortgagee.

      (e) Landlord's Receipt Of Third Party Payor Program Reimbursements. If
Landlord is required by applicable law to receive any payments from Third Party
Payors as the owner of any Facility which would be deemed payment for services
provided by or on behalf of Tenant to residents of such Facility, the parties
hereto agree that, so long as there is no existing and continuing Event of
Default hereunder, Landlord shall pay such monies to Tenant as promptly as
practicable.

8. TENANT'S COVENANT TO REPAIR.

      (a) Repair and Maintenance. Except to the extent expressly permitted to
the contrary in Paragraph 17 or Paragraph 23, Tenant shall, at all times during
the Term and at its sole cost and expense, (i) put, keep, replace and maintain
each of the Leased Properties (including, without limitation, the Improvements
and the Related Personal Property) in good repair and in good and safe order and
condition, ordinary wear and tear excepted (subject to Tenant's obligations
under clauses (ii) and (iii) below), (ii) make all repairs and replacements
thereto, both inside and outside, structural and non-structural, ordinary and
extraordinary, howsoever the necessity for repairs and replacements may occur,
and whether or not necessitated by wear, tear, obsolescence or defects, latent
or otherwise to satisfy Tenant's obligation under clause (i) above, (iii) use
all reasonable precautions to prevent waste, damage or injury, and (iv) install,
maintain and replace all landscaping, signs, sidewalks, roadways, driveways and
parking areas within each of the Leased Properties in good repair and in good
and safe order and condition, ordinary wear and tear excepted (subject to
Tenant's obligations under clauses (ii) and (iii) above). Tenant's obligations
under this Paragraph 8 shall constitute an expense of Tenant, shall not
constitute Rent and shall not offset or reduce any Rent otherwise required to be
paid hereunder.

      (b) Related Personal Property. Tenant may (and shall as provided herein
below), at its expense, affix or assemble or place on any parcels of the Land or
in any of the Improvements, any Related Personal Property, and Tenant may,
subject to the conditions set forth below, remove the same at any time, provided
it is replaced with substantially equivalent personal property sufficient to
comply with the terms of this Paragraph 8(b). Tenant shall provide and

                                       17
<PAGE>

maintain throughout the Term all such Related Personal Property as shall be
necessary in order to operate each of the Facilities for its Intended Use and in
material compliance with all applicable Legal Requirements and Insurance
Requirements. All of the Related Personal Property shall, upon the expiration or
earlier termination of this Lease, at Landlord's option, exercised by written
notice to Tenant, be either removed by Tenant, at Tenant's sole cost and
expense, or left at the applicable Facility.

9. NO LANDLORD REPAIR OBLIGATIONS. Landlord shall not be required to make any
structural or non-structural alterations, reconstructions, replacements,
changes, additions, improvements or repairs of any kind or nature whatsoever to
any of the Leased Properties or any portion thereof (including, without
limitation, any portion of the Improvements or any Related Personal Property) at
any time during the Term.

10. SURRENDER.

      (a) Surrender of Leased Property. Tenant shall on the last day of the
Term, or upon the sooner termination of this Lease, peaceably and quietly
surrender each of the Leased Properties to Landlord, in good repair and in good
and safe order and condition and, further, in at least as good condition as when
each of the Leased Properties was received, ordinary wear and tear and damage by
fire, Casualty or Condemnation excepted (but subject to Tenant's obligation to
restore the Leased Properties as provided in Paragraph 17 and Paragraph 23).

      (b) Transfer of Licenses and Permits. In addition, upon the expiration or
earlier termination of this Lease, Tenant shall, at Landlord's sole cost and
expense, with respect to each Leased Property, (i) use commercially reasonable
efforts to cooperate with Landlord or Landlord's nominee in connection with the
processing of Landlord's or such nominee's applications for Permits and Licenses
and (ii) to the extent the same are assignable or otherwise transferable by law
and pursuant to the terms thereof, transfer to Landlord or Landlord's nominee
the Permits and Licenses and all contracts, including contracts with
governmental or quasi-governmental entities which may be necessary for the
operation of the applicable Facility for its Intended Use. If requested by
Landlord, Tenant will continue to manage one (1) or more of the applicable
Facilities after the expiration of the Term and for up to six (6) additional
months, if necessary for Landlord or Landlord's nominee to obtain all necessary
Permits and Licenses on commercially reasonable terms, including, without
limitation, (i) an agreement to pay Tenant a market rate management fee (which
shall in no event be less that $10,000 per month per Facility net to Tenant
(which $10,000 per month shall be increased by the same percentage as the
Consumer Index has increased from the Base CPI Index to the Consumer Index
published most closely in time to the effective date of such management
agreement), (ii) an agreement for Landlord to pay all costs and expenses of
operating the applicable Facility, either directly or by reimbursement to
Tenant, and (iii) an agreement for Landlord to reimburse Tenant for Tenant's
reasonable out-of-pocket costs and expenses, and reasonable administrative
costs, and (iv) such other terms and conditions as Landlord and Tenant shall
mutually agree. To that end, pending completion of the transfer of the
operational control of the applicable Facility to Landlord or its nominee:

            (i) Tenant will provide all information reasonably requested by
      Landlord or its nominee for Landlord's or such nominee's use in the
      preparation and filing of any and

                                       18
<PAGE>

      all necessary applications or notifications of any federal or state
      governmental authority having jurisdiction over a change in the
      operational control of the applicable Facility, and any other information
      reasonably required to effect an orderly transfer of the applicable
      Facility; and

            (ii) Tenant shall use commercially reasonable efforts to keep the
      business and organization of the applicable Facility intact and to
      preserve for Landlord or its nominee the goodwill of the suppliers,
      distributors, residents and others having business relations with Tenant
      with respect to the applicable Facility (it being acknowledged that
      residency rates typically decline and employee turnover rates typically
      increase when a change in management becomes known).

      (c) Apportionment of Impositions, Insurance Premiums and the Minimum
Capital Additions Amount. Upon the expiration of the Term, Landlord and Tenant
shall apportion and prorate Impositions, Insurance Premiums and the Minimum
Capital Additions Amount through the Expiration Date, with Tenant being
responsible for all Impositions, Insurance Premiums and the Minimum Capital
Additions Amount relating to the period prior to the Expiration Date and
Landlord being responsible for all Impositions, Insurance Premiums and the
Minimum Capital Additions Amount relating to the period on and after the
Expiration Date.

11. CAPITAL ADDITIONS.

      (a) Construction of Capital Additions. Tenant shall not construct or
install any Capital Addition on any of the Leased Properties without obtaining
Landlord's prior written consent, which consent shall not be unreasonably
withheld, delayed or conditioned, provided that no consent shall be required for
any Capital Addition as long as (i) the Capital Additions Costs for such Capital
Addition are less than Two Hundred Fifty Thousand Dollars ($250,000.00) per
Capital Addition (including all related work), with respect to any particular
Leased Property and (ii) such construction or installation will not materially
and adversely affect or violate any Legal Requirement or Insurance Requirement
applicable to such Leased Property. Prior to commencing construction of any
Capital Addition requiring consent pursuant to the preceding sentence, Tenant
shall submit to Landlord, in writing, a proposal setting forth, in reasonable
detail, any proposed Capital Addition and shall provide to Landlord such plans
and specifications, permits, licenses, contracts and other information
concerning the proposed Capital Addition as Landlord may reasonably request.
Landlord shall have ten (10) Business Days to review all materials submitted to
Landlord in connection with any such proposal. Failure of Landlord to respond to
Tenant's proposal within ten (10) Business Days after receipt of all information
and materials requested by Landlord in connection with the proposed Capital
Addition shall be deemed to constitute approval of such proposed Capital
Addition, subject in all events, however, to Tenant's compliance with the other
requirements of this Paragraph 11. Without limiting the generality of the
foregoing, such proposal shall indicate the approximate projected cost of
constructing such Capital Addition and the use or uses to which it will be put.
No Capital Addition shall be made which would tie in or connect any Improvement
on the applicable Leased Property with any other improvements on property
adjacent to such Leased Property (and not part of the Land), including, without
limitation, tie-ins of buildings or other structures or utilities (other than a
utility facility belonging to the provider of such utility service), without
Landlord's consent, which shall be given or withheld in Landlord's discretion.
Any Capital Additions shall,

                                       19
<PAGE>

upon the expiration or sooner termination of the Term, pass to and become the
property of Landlord, free and clear of all encumbrances other than Permitted
Encumbrances.

      (b) Non-Capital Additions. Tenant shall have the right, at Tenant's sole
cost and expense, without Landlord consent, to make additions, modifications or
improvements which are not Capital Additions ("Non-Capital Additions") to any of
the Leased Properties from time to time as Tenant, in its sole discretion, may
deem desirable for the applicable Intended Use provided that any such
Non-Capital Addition will not materially alter the character or purpose or
materially detract from the value of the applicable Leased Property.

      (c) Capital Additions Financed by Landlord. Upon the request of Tenant,
Landlord may elect to finance a Capital Addition, if Landlord, Tenant and ALS
Holdings mutually agree to Tenant's performing such work (each, a "Landlord
Capital Addition"). If Landlord agrees to finance a Landlord Capital Addition,
Tenant shall provide such information as Landlord may from time to time request,
including, without limitation, the following:

            (i) Reasonable evidence that such Landlord Capital Addition will be,
      and upon completion, has been, completed in compliance with all applicable
      Legal Requirements, all Other Requirements and all Facility Mortgage
      Requirements;

            (ii) Copies of any required building, zoning and land use permits
      and approvals and, upon completion of such Landlord Capital Addition, a
      copy of the certificate of occupancy for such Landlord Capital Addition,
      if required;

            (iii) Such information, certificates, licenses, permits or other
      documents necessary to confirm that Tenant will be able to use the
      Landlord Capital Addition upon completion thereof in accordance with the
      applicable Facility's Intended Use, including all Legal Requirements and
      all Other Requirements;

            (iv) An Officer's Certificate and a certificate from Tenant's
      architect, if available, setting forth, in reasonable detail, the
      projected (or actual, if available) Capital Additions Cost and invoices
      and lien waivers from Tenant's contractors for such work;

            (v) A deed conveying to Landlord title to any land acquired for the
      purpose of constructing the Landlord Capital Addition free and clear of
      any liens or encumbrances, except those approved by Landlord, and, upon
      completion of the Landlord Capital Addition, a final as-built survey
      thereof reasonably satisfactory to Landlord;

            (vi) Endorsements to any outstanding owner's policy of title
      insurance, for Capital Additions Costs in excess of $500,000, covering the
      applicable Facility or commitments therefor, reasonably satisfactory in
      form and substance to Landlord, (A) adding any land acquired for purposes
      of constructing the Landlord Capital Addition, (B) updating the same
      without any additional exceptions except as reasonably approved by
      Landlord, and (C) increasing the coverage thereof by an amount equal to
      the Capital Additions Cost relating to such Landlord Capital Addition; and

                                       20
<PAGE>

            (vii) Copies of plans and specifications relating to such Landlord
      Capital Addition and other instruments reasonably required by Landlord.

      (d) Disbursement of Capital Addition Allowances. Provided that no Default
or Event of Default hereunder or under the Agreement Regarding Leases has
occurred and is continuing, and subject to Tenant's satisfaction of the
conditions set forth in this Paragraph 11(d) and, with respect only to any
Mandatory Capital Addition to one (1) or more of the Leased Properties, the
conditions set forth in Paragraph 5(a) of the Agreement Regarding Leases, Tenant
shall have the right upon ten (10) days' prior written notice to Landlord to
request from Landlord a disbursement of funds in connection with a Landlord
Capital Addition or a Mandatory Capital Addition (each, a "Capital Addition
Allowance"). Requests for disbursements under this Paragraph 11(d) shall not be
made more often than once during any calendar month and shall be made in
increments of not less than Twenty Five Thousand and No/100 Dollars ($25,000.00)
and in an aggregate amount not to exceed the approved Capital Additions Cost for
such Landlord Capital Addition.

            (i) Landlord shall, upon written request from Tenant and
      satisfaction of the requirements set forth in this Paragraph 11(d),
      disburse a Capital Addition Allowance to Tenant necessary to pay for the
      actual approved costs of Landlord Capital Additions (or, upon partial
      completion of such Landlord Capital Additions pursuant to Paragraph
      11(d)(vi)).

            (ii) Each request for a Capital Addition Allowance shall be in a
      form reasonably specified or approved by Landlord and shall set forth (a)
      the applicable Leased Property and the specific Landlord Capital Addition
      for which the Capital Addition Allowance is requested, (b) if the Landlord
      Capital Addition includes the purchase or replacement of specific items,
      the quantity and price of each item purchased, (c) the price of all
      materials (grouped by type or category) used in connection with the
      Landlord Capital Addition to be paid for with the Capital Addition
      Allowance, other than the purchase or replacement of specific items, and
      (d) the cost of all contracted labor or other services applicable to each
      Landlord Capital Addition for which such request for disbursement is made.

            (iii) With each request, Tenant shall certify that all Landlord
      Capital Additions to be paid for with the Capital Addition Allowance will
      be made in a good and workmanlike manner and in accordance with all
      applicable Legal Requirements of any Government Agency having jurisdiction
      over the applicable Facility.

            (iv) To the extent required by Landlord, each request for a Capital
      Addition Allowance shall include copies of invoices for all items or
      materials purchased and all contracted labor or services provided or to be
      provided as a condition to any requested disbursement, and shall include a
      waiver of lien (or conditional waiver of lien conditioned only upon
      payment of all or a portion of the requested Capital Addition Allowance)
      from each Person receiving payment prior to Landlord's disbursement, and
      from each contractor, supplier, materialman, mechanic or subcontractor or
      other Person who receives payment in an amount equal to or greater than
      $25,000.00 for completion of its work or delivery of its materials.

                                       21
<PAGE>

            (v) Any lien waiver delivered hereunder shall conform to Legal
      Requirements and shall cover all work performed and materials supplied
      (including equipment and fixtures) for the applicable Facility by that
      contractor, supplier, subcontractor, mechanic or materialman or other
      Person up to the date covered by the current disbursement request.

            (vi) Each request for a Capital Addition Allowance shall be made
      only after completion of the portion of the work with respect to the
      Landlord Capital Addition for which the Capital Addition Allowance is
      requested. Tenant shall provide Landlord with such evidence of completion
      of the portion of the Landlord Capital Addition with respect to which the
      Capital Addition Allowance is requested, which shall be satisfactory to
      Landlord in its reasonable judgment.

            (vii) Upon receipt of the requested Capital Addition Allowance,
      Tenant shall pay all invoices in connection with the Landlord Capital
      Addition relating to the applicable Capital Addition Allowance.

      (e) Capital Addition Allowances Added to Lease Basis. All Capital Addition
Allowances made by Landlord shall be added to the Lease Basis on a
dollar-for-dollar basis and the Base Rent shall be adjusted accordingly.

12. UTILITIES AND OTHER SERVICES. Tenant shall be liable for and shall pay
directly all charges, fees and amounts (together with any applicable penalties,
late charges, taxes or assessments thereon) when due for water, gas,
electricity, air conditioning, heat, septic, sewer, refuse collection, telephone
and any other utility charges or similar items in connection with the use or
occupancy of each of the Leased Properties. Landlord shall not be responsible or
liable in any way whatsoever for the quality, quantity, impairment,
interruption, stoppage, or other interference with any utility service,
including, without limitation, water, air conditioning, heat, gas, electric
current for light and power, telephone, or any other utility service provided to
or serving any of the Leased Properties or any damage or injury caused thereby.
No such interruption, termination or cessation of utility services shall relieve
Tenant of its duties and obligations pursuant to this Lease, including, without
limitation, its obligation to pay all Rent as and when the same shall be due
hereunder.

13. PERFORMANCE BY LANDLORD OF TENANT'S OBLIGATIONS.

      (a) Landlord's Self Help. If an Event of Default shall have occurred and
is continuing, Landlord may (but shall be under no obligation to), after Notice
to Tenant (or without Notice or time to perform if, in Landlord's reasonable
opinion, an emergency exists or action is necessary to cure any default under
any applicable Facility Mortgage prior to the expiration of the applicable cure
period therefor), perform the same for the account and at the expense of Tenant.
If, at any time and by reason of such Event of Default, Landlord is compelled to
pay, or reasonably elects to pay, any sum of money or do any reasonable act
which will require the payment of any sum of money, or is compelled to incur any
expense in the enforcement of its rights hereunder or otherwise, such sum or
sums, together with interest thereon at the Overdue Rate, shall be deemed
Additional Rent hereunder and shall be paid to

                                       22
<PAGE>

Landlord by Tenant promptly when billed therefor, and Landlord shall have all
the same rights and remedies in respect thereof as Landlord has in respect of
the Rent herein reserved.

      (b) Landlord's Inspections. Landlord, its agents or representatives,
including any applicable Facility Mortgagee, shall have the right, but not the
obligation, upon reasonable advance Notice to enter from time to time upon any
or all of the Leased Properties to perform inspections (including, but not
limited to, sampling) of such Leased Property or Leased Properties to confirm
that Tenant is performing all of Tenant's obligations under this Lease, that
Tenant has not violated any of its covenants under this Lease and that the
Leased Property is in compliance with the applicable Facility Mortgage. Landlord
shall use reasonable efforts to minimize any disturbance to Tenant or any
resident or occupant of the applicable Leased Property (or Leased Properties) as
a result of any such entry by Landlord, its agents or representatives. Upon
completion of such inspection, Landlord may deliver to Tenant a written report
("Inspection Report") outlining certain defaults, if any, in Tenant's
obligations under Paragraph 7(b), Paragraph 7(c) or Paragraph 8(a). Within ten
(10) Business Days after Tenant's receipt of such Inspection Report, Tenant
shall either (i) object to Landlord in writing as to any portion of the
Inspection Report, specifically describing such objection; or (ii) commence any
and all required work outlined in the Inspection Report which Tenant has not
objected to, and diligently complete such work. If Tenant objects to any item in
the Inspection Report, then within ten (10) Business Days of Landlord's receipt
of Tenant's objection notice, both Landlord and Tenant shall select a third
party licensed engineer mutually satisfactory to Landlord and Tenant or if a
single engineer cannot be agreed upon, then Landlord and Tenant shall each, at
their own cost, select a licensed engineer and the two chosen engineers shall
select a third licensed engineer, the cost of the third engineer being paid
equally by Landlord and Tenant. The engineer(s) shall determine, by majority
vote, whether the work outlined in the Inspection Report is necessary to put the
applicable Leased Property in good condition and repair, ordinary wear and tear
excepted (but subject to Tenant's covenants under clauses (ii) and (iii) of
Paragraph 8(a) and otherwise in compliance with this Lease). Such determination
shall be final and binding on Landlord and Tenant. Notwithstanding anything to
the contrary contained in this Paragraph 13(b), all inspections shall occur at
reasonable times during normal business hours and shall be conducted in a manner
aimed to minimize the disturbance or interference with (x) Tenant's and
Manager's use and operation of the applicable Facility and (y) the residents'
and occupants' use of the applicable Facility, and the scope of such inspections
shall be limited by (A) any security, health, safety or confidentiality
requirements of any Governmental Agency or imposed by applicable law or
regulations and (B) Tenant's ordinary business practices and standard residency
agreements, if any, requiring Tenant to maintain the confidential nature of
certain personal information relating to individual residents living in the
applicable Facility.

14. ENTRY. Landlord, any related Facility Mortgagee and their agents or
representatives may enter any of the Leased Properties at reasonable times
during normal business hours upon twenty-four (24) hours prior written Notice
(except during emergencies, in which case Landlord shall give reasonable notice
under the circumstances) for the purpose of performing any work which Landlord
elects pursuant to Paragraph 13(a) to undertake by reason of an Event of
Default. Landlord shall use reasonable efforts not to disturb Tenant or any
resident or occupant of the applicable Leased Property (or Leased Properties)
and not to interfere unreasonably with the use and operations of the applicable
Facility (or Facilities) as a result of any such entry by Landlord, its agents
or representatives. Landlord's right to entry with respect to the applicable

                                       23
<PAGE>

Leased Property shall be limited by (A) any security, health, safety or
confidentiality requirements of any Governmental Agency or imposed by applicable
law or regulations and (B) Tenant's ordinary contractual business practices, if
any, requiring Tenant to maintain the confidential nature of certain personal
information relating to individual residents living in the applicable Facility.

15. ASSIGNMENT, SUBLETTING AND LIENS.

      (a) Transfers Prohibited Without Consent. Except as provided below, Tenant
shall not, without the prior written consent of Landlord, which consent may be
withheld in Landlord's sole and absolute discretion, in each instance, sell,
assign or otherwise transfer Tenant's interest under this Lease, or Tenant's
interest in one (1) or more of the Leased Properties, in whole or in part, or
any rights or interest which Tenant may have under this Lease, or sublet one (1)
or more of the Leased Properties, or any part thereof. If given, the consent of
Landlord to an assignment, transfer or subletting shall in no event be construed
to relieve Tenant or such assignee or subtenant from the obligation of obtaining
the express consent in writing of Landlord to any further assignment, transfer
or subletting. For purposes of this Paragraph 15(a), a Change of Control which
is not expressly permitted in accordance with the terms of Paragraph 6 of the
Agreement Regarding Leases shall be deemed to constitute a prohibited assignment
of this Lease. Any assignment, transfer or sublease in violation of this
Paragraph 15 shall be voidable at Landlord's option. For purposes of this
Paragraph, Landlord's consent shall conclusively be deemed reasonably withheld
(i) if the proposed transfer would, in Landlord's judgment, violate the terms of
any Facility Mortgage and Tenant has not obtained the written consent (in form
satisfactory to Landlord) of the applicable Facility Mortgagee, or (ii) if the
effect of any such transfer would adversely affect the status or the treatment
of Landlord or its direct or indirect Parent as a real estate investment trust
("REIT") under applicable REIT regulations. Notwithstanding the foregoing,
except as expressly provided in Paragraph 6 of the Agreement Regarding Leases,
Landlord's consent shall not be required in connection with (x) any Permitted
Transfer, (y) any Equity Transfer or (z) any Affiliate Transfer.

      (b) Adequate Assurances. Without limiting any of the foregoing provisions
of this Paragraph 15, if, pursuant to the U.S. Bankruptcy Code, as the same may
be amended from time to time, Tenant is permitted to assign or otherwise
transfer its rights and obligations under this Lease in disregard of the
restrictions contained in this Paragraph 15, the assignee agrees to provide
adequate assurance to Landlord (i) of the continued use of the applicable Leased
Property solely in accordance with the Intended Use thereof and in compliance
with all other terms of this Lease; and (ii) of such other matters as Landlord
may reasonably require at the time of such assumption or assignment. Such
assignee shall expressly assume this Lease by an agreement in recordable form.

      (c) Permitted Subleases. Notwithstanding the foregoing, Tenant may enter
into (i) third party residency agreements with respect to the individual
residency units located at each of the Facilities, (ii) subleases for space at
each of the Leased Properties for use as a bank, beauty salon, barber shop,
laundry, commissary or healthcare purposes or other concessions and services in
the ordinary course of business consistent with and ancillary to the Intended
Use; provided, however, that any such proposed subleases with terms longer than
six (6) months shall be subject to Landlord's prior written approval, which
shall not be unreasonably withheld,

                                       24
<PAGE>

conditioned or delayed, (iii) any sublease shall be for a term that will expire
prior to the Expiration Date, and (iv) subject to Landlord's prior written
approval as to the form of sublease agreement, the identity of the proposed
tenant and the substance of such proposed sublease transaction (which will not
be unreasonably withheld), subleases with Manager in so-called "possessory
interest" Facility State where use of a sublease is required by applicable Legal
Requirements. Any sublease permitted hereunder shall not reduce the number of
units at the applicable Facility and will not violate or affect any Legal
Requirement or Insurance Requirement, and Tenant shall maintain (or cause any
sublessee to maintain) such additional insurance coverage with respect to the
activities to be conducted in such subleased space as Landlord may reasonably
require so long as such additional insurance coverage is customarily maintained
for comparable activities and uses at comparable properties.

      (d) Whole Facility Subleases. Notwithstanding anything to the contrary set
forth herein, upon Tenant's satisfaction of the conditions set forth below in
this clause (d), Tenant shall be permitted to sublease up to six (6) of the
Facilities to third party owner/operators of independent living facilities or
senior living facilities. Any subleases under this Paragraph 15(d) shall be
subject to the satisfaction of the following conditions: (i) Tenant shall have
received Landlord's prior written consent both with respect to the identity of
the proposed sublessee and with respect to the form and content of the proposed
sublease, which consent under this clause (i) shall not be unreasonably
withheld, (ii) if required under the terms of any applicable Facility
Mortgage(s) affecting the Leased Properties proposed to be subleased, Tenant
shall have received the applicable Facility Mortgagee's prior written consent to
such sublease, (iii) Tenant shall promptly after demand by Landlord reimburse
Landlord and any applicable Facility Mortgagee for any out-of-pocket costs
(including reasonable attorneys' fees and disbursements) incurred by Landlord or
any such Facility Mortgagee in reviewing the proposed sublease documents or any
preparing any consent agreements, (iv) the sublease by its terms shall be
expressly subject and subordinate to the interests of Landlord under this Lease,
and any such sublease shall provide that upon the termination of this Lease, at
Landlord's option, such sublease will either (x) terminate and be of no further
force and effect, whereupon the subtenant shall immediately quit and vacate the
Leased Property, or (y) continue in effect as a direct lease between Landlord ,
as the landlord thereunder, and the subtenant, as the tenant thereunder, (v) the
terms of the subleasing transaction shall otherwise comply with Paragraph 15(c),
and (vi) Landlord shall have determined, in Landlord's discretion reasonably
exercised, that Tenant's entering into the proposed sublease would not adversely
affect the status or the treatment of Landlord or its direct or indirect Parent
as a REIT under applicable REIT regulations. If Tenant enters into one (1) or
more subleases contemplated under this Paragraph 15(d), Tenant shall remain
fully liable for all of Tenant's obligations under this Lease, and no such
sublease shall release or relieve Tenant of any of Tenant's duties or
obligations under this Lease, including, without limitation, the obligation to
pay Rent applicable to any sublet Leased Property.

      (e) Liens. Subject to the provisions of Paragraph 26, Tenant shall not,
directly or indirectly, create or allow to remain and shall promptly discharge
or bond over in a manner reasonably satisfactory to Landlord, at its expense,
any Lien encumbering one (1) or more of the Leased Properties or Tenant's
leasehold interest therein or any attachment, levy, claim or encumbrance in
respect of the Rent, other than (i) Permitted Encumbrances; (ii) restrictions,
liens and other encumbrances which are consented to in writing by Landlord or
otherwise permitted under this Lease; (iii) Liens for those taxes of Landlord
which Tenant is not required to pay

                                       25
<PAGE>

hereunder; (iv) Liens for Impositions or for sums resulting from purported
noncompliance with Legal Requirements so long as (A) the same are not yet
payable, or (B) are being contested in accordance with Paragraph 26; (v) liens
of mechanics, laborers, materialmen, suppliers or vendors incurred in the
ordinary course of business that are not yet due and payable or are for sums
that are being contested in accordance with Paragraph 26; and (vi) any Facility
Mortgage or other liens which are the responsibility of Landlord pursuant to the
provisions of Paragraph 35.

16. IMPOSITIONS. Throughout the Term, Tenant shall bear, pay and discharge all
Impositions which become due and payable during, arise during, accrue during or
otherwise relate to the period comprising (a) the Term or (b) any period prior
to the commencement of the Term. Upon request of Landlord, Tenant shall promptly
furnish to Landlord satisfactory evidence of the payment of any Imposition
required to be paid by Tenant pursuant to the foregoing. If, pursuant to the
terms of any Facility Mortgage, Landlord is required to establish and fund
payments of Impositions to an escrow reserve account established under the loan
documents relating to such Facility Mortgage, then Tenant shall fund all such
payments to the reserve account, and such payments shall constitute Additional
Rent hereunder. Upon the expiration of the Term, Landlord and Tenant shall
apportion and prorate Impositions to the Expiration Date, with Tenant being
responsible for all Impositions relating to the period prior to the Expiration
Date and Landlord being responsible for all Impositions relating to the period
on and after the Expiration Date, as more particularly described in Paragraph
10.

17. CASUALTY.

      (a) Restoration and Repair. If the Improvements and/or the Related
Personal Property at any Leased Property shall be destroyed or damaged in whole
or in part by fire or any cause whatsoever ("Casualty"), Tenant shall give
Landlord prompt written notice thereof. If such Casualty does not render the
individual Leased Property Unsuitable for its Intended Use, and if the
applicable Facility Mortgagee applies all or any portion of the applicable
insurance proceeds to repay the applicable Facility Mortgage and therefore any
portion of the proceeds is not available for restoration, or the Facility
Mortgagee otherwise refuses in writing to make any portion of such proceeds
available to be used for restoration within a commercially reasonable period of
time in light of the nature of the Casualty event, then Landlord, in Landlord's
sole and absolute discretion, may elect to make available to Tenant funds in an
amount equal to the amount of the proceeds so applied or withheld, as the case
may be, by such Facility Mortgagee. If Landlord elects not to make such funds
available for restoration, Tenant may, by written Notice to Landlord terminate
this Lease as to the applicable Facility by electing a Limited Termination
Election with respect thereto, in which case the provisions of Paragraph 17(b)
shall apply. If the applicable insurance company or Landlord elects to fund the
proceeds for restoration (as more particularly described in Paragraph 17(b)),
then upon Tenant's receipt of proceeds or funds from the insurance carrier or
Landlord as described above, Tenant shall repair, reconstruct or replace the
Improvements and/or the Related Personal Property, or the portion thereof so
destroyed or damaged (whichever is reasonably required), at least to the extent
practicable to a condition substantially equivalent in value and character as
existed immediately prior to such Casualty, and in accordance with all Legal
Requirements, all Insurance Requirements, all Facility Mortgage Requirements and
all Other Requirements. All such work shall be started as soon as practicable
and completed at Tenant's sole cost and expense if the

                                       26
<PAGE>

amount of insurance proceeds are insufficient to complete the project (provided
Tenant actually receives all such proceeds either from the insurance company or,
if any portion of such proceeds is held by the Facility Mortgagee, then from
Landlord), and Tenant shall immediately take such action as is necessary to
secure the applicable Leased Property (or any portion thereof) such that the
same does not constitute a nuisance or otherwise present a health or safety
hazard. Notwithstanding the occurrence of any such Casualty, Tenant shall
continue to pay all Rent without abatement.

      (b) Unavailability of Proceeds. Upon the occurrence of a Casualty in which
any individual Leased Property is rendered Unsuitable for its Intended Use, and
if the applicable Facility Mortgagee (i) applies all or any portion of the
applicable insurance proceeds to repay the applicable Facility Mortgage and
therefore any portion of the proceeds are not available for restoration or (ii)
otherwise refuses in writing to make any portion of such proceeds available to
be used for restoration within a commercially reasonable period of time in light
of the nature of the Casualty event, then, unless Landlord, in Landlord's sole
and absolute discretion, agrees to make available to Tenant funds in an amount
equal to the amount of proceeds so applied or withheld as aforesaid by such
Facility Mortgagee, Tenant may elect by written notice to Landlord ("Limited
Termination Election") to terminate this Lease as it relates to the applicable
Leased Property. Upon Landlord's receipt of a Limited Termination Election under
this Paragraph 17(b) or under Paragraph 17(a), Landlord shall notify Tenant in
writing as to whether Landlord intends to make such funds available and shall
deliver such notice to Tenant not later than ten (10) Business Days after
receiving written notice from the applicable Facility Mortgagee that such
Facility Mortgagee has applied or intends to apply (or has made a final
determination not to disburse) the insurance proceeds (it being acknowledged and
agreed by the parties hereto that if Landlord advances any funds under this
Paragraph 17(b), the Lease Basis will not be increased in connection with any
such funding). Such Limited Termination Election shall be exercised, if at all,
by written termination notice given during the fifteen (15) Business Day period
after Tenant's receipt of such notice from Landlord (time being of the essence
with respect to the giving of such termination notice by Tenant within such time
period), and shall be effective on the day on which the applicable insurance
company (or insurance companies) fund the proceeds of the applicable insurance
policies and the proceeds thereof are actually applied by the applicable
Facility Mortgagee in reduction of the principal amount of the applicable
Facility Mortgage. Upon the effective date of the transactions contemplated by
the Limited Termination Election (i) Tenant shall immediately (x) assign
Tenant's rights in and to all insurance proceeds for such damage or destruction
to Landlord and any applicable Facility Mortgagee, and (y) pay to Landlord an
amount equal to the deductible or self-insured retention amount under each
insurance policy under which a claim was paid, and (ii) from and after such
effective date until the Expiration Date, the Rent payable monthly under this
Lease shall be reduced in an amount equal to the Deleted Property Rent
Adjustment, and the applicable Deleted Property shall no longer be considered a
Leased Property for the purposes of this Lease other than Paragraph 18(f) and
Paragraph 19(c).

      (c) Escrow of Insurance Proceeds. Subject to the requirements of any
Facility Mortgagee, in the event of a Casualty resulting in an insurance loss
payment for any Improvements and/or Related Personal Property in an amount
greater than Two Hundred Fifty Thousand Dollars ($250,000.00), unless this Lease
is terminated as provided in Paragraph 17(a) or Paragraph 17(b), the proceeds of
all insurance policies maintained by Tenant plus the amount

                                       27
<PAGE>

of any deductible (to be deposited by Tenant) shall, subject to all Legal
Requirements and to the terms of any Facility Mortgage, be deposited in the name
of Landlord, Tenant and any applicable Facility Mortgagee in an escrow account
at an approved financial institution designated by Landlord or the Facility
Mortgagee (which depositary may be the Facility Mortgagee) (the "Escrow Agent"),
and shall be used by Tenant for the repair, reconstruction or restoration of the
Improvements and/or Related Personal Property. Such proceeds shall be disbursed
periodically by the Escrow Agent upon certification of the general contractor,
architect or engineer having supervision of the work that such amounts are the
amounts paid or payable for the repair, reconstruction or restoration. Tenant
shall, at the time of establishment of such escrow account and from time to time
thereafter until said work shall have been completed and paid for, furnish
Landlord with adequate evidence that at all times the undisbursed portion of the
escrowed funds, together with any funds made available by Tenant, is sufficient
to pay for the repair, reconstruction or restoration in its entirety. Subject to
the requirements of a Facility Mortgage, if a Casualty results in a loss payment
for the Improvements and/or Related Personal Property in an amount equal to or
less than Two Hundred Fifty Thousand Dollars ($250,000.00), unless this Lease is
terminated as provided in Paragraph 17(b), then the proceeds shall be paid to
Tenant, and shall be applied by Tenant toward the repair, reconstruction and
restoration of the Leased Property. Tenant shall obtain, and make available to
Landlord, receipted bills and, upon completion of the work, full and final
waivers of lien.

      (d) Uninsured Losses. Nothing contained herein shall relieve Tenant of its
obligations under this Paragraph 17 even if the Casualty is not covered, either
in whole or in part, by insurance.

      (e) Deletion of Properties. If this Lease is terminated as to one (1) or
more Leased Properties (but not all of the Leased Properties) in connection with
a Casualty (in accordance with this Paragraph 17) or a Condemnation (in
accordance with Paragraph 23), the provisions of this Paragraph 17(e) shall be
applicable. Without necessity of any further action of the parties, this Lease
shall terminate as to the Deleted Property(ies), and the Deleted Property(ies)
shall be separated and removed herefrom, on the effective date of such removal
(each such date, a "Property Removal Date") as set forth under the express terms
of Paragraph 17 or Paragraph 23. As of the applicable Property Removal Date,
this Lease shall be automatically and ipso facto amended to: (i) delete and
eliminate the Deleted Property(ies) herefrom; and (ii) exclude the applicable
Deleted Property(ies) from the definition of Leased Property (except with
respect to Tenant's obligations under Paragraph 18(f) or Paragraph 19(c)). The
terms of items (i) and (ii) above shall not limit the liability of Tenant in
case of any termination of this Lease as it relates to an applicable Deleted
Property in connection with a Casualty (in accordance with Paragraph 17) or a
Condemnation pursuant to Paragraph 23 for any other amounts then owed by Tenant
to Landlord with respect to the related Leased Property, and the deletion of one
(1) or more of the Leased Properties from this Lease shall not reduce the Lease
Basis or otherwise affect or reduce the obligations of Tenant hereunder, except
for reducing the Rent by the Deleted Property Rent Adjustment. Tenant and
Landlord shall execute and enter into an amendment to this Lease reflecting the
elimination of any Deleted Property(ies) herefrom at the effective date of the
Limited Termination Election for such Deleted Property.

18. INSURANCE.

                                       28
<PAGE>

      (a) Insurance By Tenant. Tenant shall, throughout the Term, and at its
sole cost and expense, maintain in full force and effect the types and amounts
of insurance required under each of the Facility Mortgages or, if there is no
Facility Mortgage affecting the applicable Leased Property or if the applicable
Facility Mortgagee does not require the maintenance of insurance, the following
types and amounts of insurance coverage with respect to each of the Leased
Properties; provided such insurance coverage is commercially available at
commercially reasonable rates:

            (i) Hazard Insurance. Tenant shall keep the Improvements and the
      Related Personal Property at each of the Leased Properties, including all
      permitted alterations, changes, additions and replacements thereof and
      thereto, insured against loss or damage caused by: (A) fire, and other
      hazards and perils generally included under extended coverage; (B)
      sprinkler leakage; (C) vandalism and malicious mischief; (D) boiler and
      machinery; and (E) other perils commonly covered by "All Risk" insurance,
      all in an amount which reasonably assures there will be sufficient
      proceeds to replace such Improvements and the Related Personal Property in
      the event of a loss against which such insurance is issued but in no event
      less than 100% of the full replacement value thereof (exclusive of
      foundations). Such insurance shall contain (x) "Ordinance or Law Coverage"
      (if any of the related Improvements at such Leased Property or the use of
      the applicable Leased Property shall at any time constitute legal
      non-conforming structures or uses which non-conformance shall be presumed
      unless and until Tenant proves to Landlord's reasonable satisfaction, that
      such uses are conforming), "Operation of Building Laws," or "Enforcement"
      endorsement, (y) "demolition" insurance (in an amount of at least
      $5,000,000) and (z) "increased cost of construction" endorsement (equal to
      at least $5,000,000). All insurance required hereunder, and all other
      insurance maintained by Tenant on the Improvements and the Related
      Personal Property in excess of or in addition to that required hereunder,
      shall be carried in favor of Landlord, any related Facility Mortgagee and
      Tenant, as their respective interests may appear.

            (ii) Liability Insurance. Tenant shall provide and keep in full
      force and effect a policy of general public liability and property damage
      insurance providing coverage against liability for personal injury, death
      and property damage having limits of not less than Five Million Dollars
      ($5,000,000) in the aggregate. Such insurance shall (A) continue at not
      less than the aforesaid limits until required to be changed by Landlord by
      reason of changed economic conditions making such protection inadequate,
      and (B) cover at least the following: (1) premises and operations; (2)
      products and completed operations on an "if any" basis; (3) independent
      contractors; (4) blanket contractual liability for all insured contracts;
      (5) contractual liability covering indemnities, if any, given by Tenant
      contained any applicable Facility Mortgage, to the extent the same is
      available; (6) broad form property damage; (7) personal injury (including
      death resulting therefrom); (8) healthcare professional liability and (9)
      a liquor liability endorsement if alcoholic beverages are sold at the
      applicable Leased Property.

            (iii) Business Interruption. Tenant shall provide and keep in effect
      a policy of business interruption insurance in an amount to cover costs,
      damages, lost income, expenses, Base Rent, and all other sums payable
      under this Lease for a period of not less than eighteen (18) months from
      the date of casualty or loss. Such insurance shall

                                       29
<PAGE>

(A) cover all risks required to be covered by the insurance provided for in
clause (i) above and clause (vii) below; (B) be in an amount sufficient to avoid
any co-insurance penalty; and (C) contain an extended period of indemnity
endorsement that provides that after the physical loss to the applicable Leased
Property has been repaired, the continued loss of income will be insured until
such income returns to the same level it was prior to the loss, or the
expiration twelve (12) months from the date of the repair, whichever first
occurs, and notwithstanding that the policy may expire prior to the end of such
period.

            (iv) Worker's Compensation and Employer's Liability Insurance.
      Tenant shall provide and keep in full force and effect workers'
      compensation insurance, in a form prescribed by the laws of the applicable
      Facility State for each of the Leased Properties, and employers' liability
      insurance with limits of not less than One Million Dollars ($1,000,000).

            (v) Builder's Risk Insurance. Tenant shall, prior to the
      commencement of and during the construction of any restoration, renovation
      or alteration to any of the Leased Property, provide and keep in full
      force and effect builder's risk insurance equal to the total cost of the
      project.

            (vi) Flood Insurance. If any Improvements relating to any of the
      Leased Properties are or become located in an area which is considered a
      flood risk by the U.S. Department of Housing and Urban Development, Tenant
      shall provide and keep in effect a policy of flood insurance with the
      maximum limit of coverage available for the Improvements under the
      National Flood Insurance Act of 1968, the Flood Disaster Protection Act of
      1973 or the National Flood Insurance Reform Act of 1994.

            (vii) Boiler and Machinery Insurance. Tenant shall provide and keep
      in effect a policy of broad form boiler and machinery insurance (without
      exclusion for explosion) covering all boilers or other pressure vessels,
      machinery, and equipment located in, on or about any of the Leased
      Properties (including "system breakdown coverage") in an amount equal to
      or greater than the repair and full replacement cost of such equipment and
      insurance against loss of occupancy or use arising from any breakdown of
      such equipment on a so-called "accident basis" and in such amounts as are
      generally required by institutional lenders for properties comparable to
      the applicable Leased Property.

            (viii) Motor Vehicle Insurance. Tenant shall provide and keep in
      effect motor vehicle liability coverage for all owned and non-owned
      vehicles, including rented and leased vehicles, used in connection with
      the operation of the Leased Property, containing minimum limits per
      occurrence of One Million and No/100 Dollars ($1,000,000.00).

            (ix) "Dram-Shop" Insurance. If alcoholic beverages are sold at any
      of the Leased Properties, Tenant shall provide and keep in effect a policy
      of so-called "dramshop" insurance or other liability insurance required in
      connection with the sale of alcoholic beverages containing minimum limits
      per occurrence of One Million and No/100 Dollars ($1,000,000.00).

                                       30
<PAGE>

            (x) Fidelity Insurance. Tenant shall provide and keep in effect a
      policy of insurance against employee dishonesty in an amount not less than
      One Million and No/100 Dollars ($1,000,000) and with a deductible not
      greater than Twenty-five Thousand and No/100 Dollars ($25,000.00).

            (xi) Healthcare Professional Liability Insurance. Tenant shall
      provide and keep in effect a policy of insurance covering claims arising
      out of healthcare professional liability in an amount as stated in clause
      (ii) of this Paragraph 18(a), and, if written on a "claims-made" basis,
      Tenant shall also provide continuous liability coverage for claims arising
      during the Term either by obtaining an endorsement providing for an
      extended reporting period reasonably acceptable to Landlord if such policy
      is cancelled or not renewed for any reason whatsoever, or by obtaining
      "tail" insurance coverage providing coverage for a period of at least
      twelve (12) months beyond the expiration of the Term.

            (xii) Earthquake Insurance. If any of the Leased Properties is in a
      high probability earthquake area (i.e., Zone 1 and 2), and a probable
      maximum loss ("PML") study reveals that the PML is greater than 10% of the
      replacement cost (as determined by Landlord), then earthquake insurance
      must be maintained in an amount equal to the PML percentage of the
      replacement cost with a deductible not to exceed 5% of the values at risk.
      The insurance pursuant to this clause (xii) shall be on terms consistent
      with the comprehensive all risk insurance policy required under clause (i)
      above.

            (xiii) Terrorism Insurance. If the insurance required under
      Paragraph 18(a)(i) above excludes coverage for acts of terrorism, Tenant
      shall provide terrorism insurance coverage in an amount equal to the full
      replacement cost of the applicable Leased Property or Leased Properties,
      unless such terrorism insurance coverage is (i) waived by Landlord, (ii)
      unable to be procured from any carrier of such insurance, or (iii) not
      available at commercially reasonable rates and not being carried by owners
      or operators of similarly situated properties.

            (xiv) Other Insurance. In addition, Tenant shall, at Landlord's
      request, provide and keep in full force and effect such other insurance
      for such risks and in such amounts as may from time to time be required
      pursuant to any Facility Mortgage or by any Legal Requirements or as
      Landlord may, from time to time, reasonably request against such other
      insurable hazards or casualties that at the time are commonly insured
      against in the case of business operations similar to those contemplated
      by this Lease or for properties similar to the Leased Properties located
      in or around the region in which each of the Leased Properties is located
      including, without limitation, wind, sinkhole, mine subsidence and
      environmental insurance, due regard being given to the height and type of
      each of the applicable Leased Properties, construction, location, use and
      occupancy. In addition, with respect to the insurance policies required
      under clauses (iv), (viii), (ix), (x) and (xi) of this Paragraph 18,
      Landlord shall have the right on Notice to Tenant to change the limits of
      said policies by reason of changed economic conditions making such
      protection inadequate in Landlord's discretion, but only to the extent
      that such revised increased limits are customarily carried and maintained
      by companies engaged in businesses similar to Tenant's and operating
      properties similar to the Leased Properties.

                                       31
<PAGE>

      (b) Landlord as Additional Insured and/or Loss Payee. Any and all
insurance maintained by Tenant as required by this Lease, or in excess of or in
addition to that required hereunder, shall name Landlord and any Facility
Mortgagee as additional insureds, as their interests may appear, and shall
contain waiver of subrogation endorsements from its insurance carrier. Landlord
and any Facility Mortgagee shall be named as the loss payee on all property
policies.

      (c) Carriers and Features. All insurance policies (except those required
under clause (a)(ii) and clause (a)(xi) of Paragraph 18(a) required to be
carried by Tenant as provided in this Paragraph 18 shall be issued by insurance
companies authorized and/or licensed to do business in the Facility State with a
Best's Insurance Rating of not less than "A-" or a Best's Financial Category of
not less than "VIII", with reasonable deductibles per occurrence. All such
policies shall be for periods of not less than one year. At least fifteen (15)
days prior to the expiration of any such policy, Tenant shall provide evidence,
reasonably satisfactory to Landlord, of Tenant's policy renewal options and
evidence that such policy renewal will be in place prior to the expiration
thereof. All such policies shall require not less than thirty (30) days written
notice to Landlord prior to any cancellation thereof or any change reducing
coverage thereunder. Notwithstanding the foregoing, Tenant may elect to obtain
blanket insurance for each of the foregoing required types of insurance.

      Tenant shall pay the premiums for all insurance policies which Tenant is
obligated to carry under this Paragraph 18 and, prior to the expiration of any
such policy, deliver to Landlord a copy of the renewal policy or policies, or,
if Landlord or any related Facility Mortgagee requests, a certificate or
certificates thereof, along with evidence that the premiums therefor have been
paid for through, at least, the next ensuing monthly period or longer as may be
required by the premium installment plan offered by the insurer(s) or premium
finance company(ies). If, pursuant to the terms of any Facility Mortgage,
Landlord is required to establish and fund payments for insurance premiums to
any escrow reserve account established under the loan documents relating to such
Facility Mortgage, then Tenant shall fund all such payments to the reserve
account, and such payments shall constitute Additional Rent hereunder. Any such
funds, paid to an escrow reserve account in connection with insurance premiums
shall, subject to the terms of the applicable Facility Mortgage, be used to pay
for insurance policies required under the Facility Mortgage. Upon the expiration
of the Term, Landlord and Tenant shall apportion and prorate funds on deposit in
any such reserve account, with Tenant being responsible for all insurance
premiums relating to the period prior to the Expiration Date and Landlord being
responsible for all insurance premiums relating to the period on and after the
Expiration Date.

      (d) Failure to Procure Insurance. If Tenant fails to procure insurance
required under this Paragraph or fails to maintain the same in full force and
effect continuously during the Term, Landlord shall be entitled to procure the
same and Tenant shall immediately reimburse Landlord for such premium expense as
Additional Rent.

      (e) Intentionally Omitted.

      (f) Indemnification of Landlord. Notwithstanding the existence of any
insurance provided for herein and without regard to the policy limits of any
such insurance, Tenant shall protect, indemnify and hold harmless Landlord for,
from and against all liabilities, obligations,

                                       32
<PAGE>

claims, damages, penalties, causes of action, costs and reasonable expenses
(including, without limitation, reasonable attorneys' fees), to the maximum
extent permitted by law, imposed upon or incurred by or asserted against
Landlord (except to the extent that any of the following result from Landlord's
gross negligence or willful misconduct after the Commencement Date) by reason
of: (i) any accident, injury to or death of persons or loss of or damage to
property occurring on or about any of the Leased Properties or adjoining
sidewalks or right of way, including, without limitation, any claims of
malpractice; (ii) any past, present or future use, misuse, non-use,
non-compliance, condition, management, maintenance or repair by Tenant or anyone
claiming under Tenant of any of the Leased Properties or the Related Personal
Property or any litigation, proceeding or claim by Government Agencies or other
third parties (other than Condemnation proceedings) to which Landlord is made a
party or participant relating to any of the Leased Properties or the Related
Personal Property or such use, misuse, non-use, non-compliance, condition,
management, maintenance, or repair thereof; (iii) any Impositions (which are the
obligation of Tenant to pay pursuant to the applicable provisions of this
Lease), and (iv) any failure or inability of Tenant to obtain the insurance
coverage required hereunder. If at any time Landlord shall have received written
notice of the assertion of a claim, Landlord shall give reasonably prompt
written notice of such claim to Tenant, provided that (x) Landlord shall have no
liability for the failure to give notice of any claim of which Tenant has
otherwise been notified or has actual knowledge, and (y) the failure of Landlord
to give such a notice to Tenant shall not limit the rights of Landlord or the
obligations of Tenant with respect to such claim, except to the extent that
Tenant suffers actual monetary loss as a result of such failure. Tenant shall
pay all amounts payable under this Paragraph 18(f) within fifteen (15) Business
Days after demand therefor, and if not timely paid, such amounts shall bear
interest at the Overdue Rate from the date payment thereof is required hereunder
to the date of payment. Tenant shall have the right to control the defense and
settlement of any such claim (but Tenant, without Landlord's prior written
consent, which Landlord may withhold in Landlord's sole and absolute discretion,
shall not be permitted to settle any claim if such settlement would admit
criminal liability of Landlord), and Tenant, at its expense, shall contest,
resist and defend any such claim, action or proceeding asserted or instituted
against Landlord or may compromise or otherwise dispose of the same, with
Landlord's prior written consent (which consent may not be unreasonably
withheld, delayed or conditioned), provided no such consent shall be required if
the compromise or settlement shall result in a complete release of Landlord from
the claim so compromised or settled). Landlord shall have the right (but not the
obligation), at Landlord's election and sole cost and expense, to participate in
the defense of any such claim, and Tenant shall have no obligation to reimburse
Landlord for any attorneys' fees incurred by Landlord in connection with same.
The obligations of Tenant under this Paragraph 18(f) are in addition to the
obligations set forth in Paragraph 19(c) and shall survive the termination of
this Lease for two (2) years.

19. ENVIRONMENTAL MATTERS.

      (a) Tenant's Covenant. Throughout the Term, Tenant covenants that it shall
not cause, permit or allow any Hazardous Materials to be placed, stored, dumped,
dispensed, deposited, used, transported, located, generated or subject to a
Release on any of the Leased Properties in violation of any Environmental Law.
Tenant shall not install or permit the installation of any underground storage
tanks, above ground storage tanks, surface impoundments or asbestos-containing
materials on any of the Leased Properties, unless Landlord consents in writing
prior to the installation. With respect to any asbestos or any
asbestos-

                                       33
<PAGE>

containing materials located on or within any of the Leased Properties, Tenant
will perform all necessary actions, including, but not limited to, operation and
maintenance that are necessary to avoid exposing any Person to asbestos or
asbestos-containing materials.

      (b) Clean-Up. During the Term, to the extent required by any applicable
Environmental Laws, Tenant shall (i) Remediate the applicable Leased Property to
comply with any and all Environmental Laws regarding Hazardous Materials and
Remediation thereof, and (ii) pay for all Remediation costs at no cost to
Landlord; provided, in each case, such Hazardous Materials were placed, used,
transported, generated or subject to a Release prior to the end of the Term and
do not result from any act or omission after the date hereof of Landlord (other
than a failure to perform Remediation) or any other indemnity hereunder.

      (c) Indemnification. Tenant shall indemnify, release and hold harmless
Landlord, its successors, assigns, members, managers, officers, directors,
shareholders and employees, from and against all Liabilities (as defined below),
suffered by, incurred by or assessed against such parties, their agents or other
representatives, whether incurred as a result of legal action taken by any
Government Agency, taken by any private claimant, or taken by Landlord, before
or after the expiration of the Term as a result of the Release or Remediation of
any Hazardous Materials upon or under, on or off site, associated with,
generated on or flowing or originating from any of the Leased Properties prior
to the end of the Term, provided such Liabilities do not arise as a result of
any act or omission after the Commencement Date by Landlord (other than a
failure to perform Remediation) or any other indemnitee hereunder. The term
"Liabilities" as used in this Paragraph 19 is hereby defined as any and all
liabilities, expenses, demands, damages, punitive or exemplary damages,
consequential damages, costs, Remediation costs, losses, causes of action,
claims for relief, reasonable attorneys' fees, other professional fees,
penalties, fines, assessments and charges. Tenant shall have the right to
control the defense or settlement of any such claim (except that Tenant shall
not be authorized to settle criminal charges against Landlord without obtaining
Landlord's, prior written consent, which may be withheld in Landlord's sole and
absolute discretion), and Tenant, at its expense, shall contest, resist and
defend any such claim, action or proceeding asserted or instituted against
Landlord or may compromise or otherwise dispose of the same, with Landlord's
prior written consent (which consent may not be unreasonably withheld, delayed
or conditioned, provided no such consent shall be required if the compromise or
settlement shall result in the complete release of Landlord from the claim so
compromised or settled). Landlord shall have the right (but not the obligation),
at its election and sole cost and expense, to participate in the defense of any
such claim, and Tenant shall have no obligation to reimburse Landlord for any
attorneys' fees incurred by Landlord in connection with same. The provisions of
this Paragraph 19 shall survive the expiration or sooner termination of this
Lease for two (2) years.

      (d) Notice. Tenant shall promptly notify Landlord of any pending or
threatened claim concerning Environmental Laws and/or Hazardous Material and one
(1) or more of the Leased Properties, for which Tenant has received written
notice. All such notices shall describe in reasonable detail the nature of such
fact, circumstance, condition, occurrence or environmental claim and, where
applicable, Tenant's response thereto. Tenant shall provide additional
information relating to any of the foregoing in such detail as may be reasonably
requested by Landlord.

                                       34

20. COSTS AND ATTORNEYS' FEES. If either party shall bring an action to recover
any sum due hereunder, or for any breach hereunder, and shall obtain a judgment
or decree in its favor, the court may award to the prevailing party in such
action its reasonable costs and reasonable attorneys' fees, specifically
including reasonable attorneys' fees incurred in connection with any appeals
(whether or not taxable or assessable as such by law). Landlord shall also be
entitled to recover Landlord's reasonable attorneys' fees and costs incurred in
any bankruptcy action filed by or against Tenant, including, without limitation,
those incurred in seeking relief from the automatic stay, in dealing with the
assumption or rejection of this Lease, in any adversary proceeding, and in the
preparation and filing of any proof of claim.

21. DEFAULT; REMEDIES.

      (a) Default. Upon the occurrence and during the continuance of any one or
more of the following events (each, an "Event of Default"), Landlord shall have
the right to exercise any rights or remedies available in this Lease, at law or
in equity. Events of Default shall consist of:

            (i) Tenant's failure to pay when due any regularly scheduled payment
      of Rent, and such failure is not cured within five (5) days (or such
      earlier period as set forth in this Paragraph 21(a)); provided, however,
      that no Event of Default shall be deemed to have occurred under this
      Paragraph 21(a)(i), if Tenant or ALS Holdings cures such failure to pay,
      pursuant to the terms of the Agreement Regarding Leases or otherwise,
      within such five (5) day period;

            (ii) Tenant's failure to pay when due any other payment of Rent, or
      any other sum of money payable hereunder (whether as Additional Rent or
      otherwise) and such failure is not cured within five (5) days after
      receipt of Notice thereof from Landlord; provided, however, that no Event
      of Default shall be deemed to have occurred under this Paragraph
      21(a)(ii), if Tenant or ALS Holdings cures such failure to pay, pursuant
      to the terms of the Agreement Regarding Leases or otherwise, within such
      five (5) day period;

            (iii) Tenant's failure to perform any other of the terms, covenants
      or conditions contained in this Lease if not remedied within thirty (30)
      days after receipt of Notice thereof, or, if such default cannot
      reasonably be remedied within such period, Tenant does not within thirty
      (30) days after Notice thereof commence such act or acts as shall be
      necessary to remedy the default and shall not thereafter diligently
      complete such act or acts within a reasonable time, provided, however, in
      no event shall such cure period extend beyond one hundred eighty (180)
      days after Notice thereof;

            (iv) if Tenant, Lease Guarantor or Guarantor becomes bankrupt or
      insolvent, or files any debtor proceedings, or files pursuant to any
      statute a petition in bankruptcy or insolvency or for reorganization, or
      files a petition for the appointment of a receiver or trustee for all or
      substantially all of its assets, or (x) any of the foregoing are filed
      against Tenant, Lease Guarantor or Guarantor, and such petition or
      appointment shall not have been set aside within ninety (90) days after
      the date of such petition or appointment, or (y) Tenant, Lease Guarantor
      or Guarantor makes 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 Tenant's interest in this Lease is attached, levied upon,
      seized or made subject

                                       35
<PAGE>

      to any other judicial seizure and such seizure or attachment is not
      discharged within ninety (90) days;

            (v) if Tenant fails to provide insurance coverage (or allows such
      coverage to be canceled or lapse) pursuant to its obligation hereunder;

            (vi) if any of Tenant, Lease Guarantor or Guarantor is liquidated or
      dissolved, or begins proceedings toward such liquidation or dissolution,
      or, in any manner, permits the sale or divestiture of substantially all of
      its assets;

            (vii) if a default occurs under Paragraph 15;

            (viii) if (x) there has been a final, unappealable revocation of any
      license, permit, certification or approval required for the lawful
      operation of any of the Facilities in accordance with its Intended Use, or
      (y) any license, permit, certification or approval required for the lawful
      operation of any of the Facilities is materially limited and, as a result
      of such limitation, Tenant experiences a material adverse effect on the
      operation of the Leased Properties, taken as a whole, for their respective
      Intended Use;

            (ix) if Tenant voluntarily ceases operation of any of the Leased
      Properties for its Intended Use, except as a result of Casualty or partial
      or complete Condemnation;

            (x) if Tenant fails to pay for money borrowed or for the deferred
      purchase price of any material property or services (excluding trade
      accounts payable in the ordinary course of business on customary trade
      terms) or any guaranty relating thereto which, in the aggregate, exceeds
      Two Hundred Fifty Thousand Dollars ($250,000), and the same be declared to
      be or become due and payable prior to the stated maturity thereof and all
      applicable notices with respect thereto have been given and all applicable
      grace or cure periods with respect thereto shall have lapsed;

            (xi) Intentionally Omitted;

            (xii) Intentionally Omitted;

            (xiii) any material representation or warranty made by Tenant in
      this Lease is determined to have been false when made;

            (xiv) the issuance or entry against Tenant of any final,
      unappealable award or judgment (or any appeal periods have expired) in an
      amount of Two Hundred Fifty Thousand Dollars ($250,000.00) or more, and
      such award or judgment shall continue unsatisfied and in effect for a
      period of ten (10) consecutive days without demonstrating that any
      insurance policy exists that would cover such award or judgment;

            (xv) the issuance or entry against Lease Guarantor or Guarantor of
      any final, unappealable award or judgment (after any appeal period have
      expired) in an amount of One Million Six Hundred Thousand Dollars
      ($1,600,000.00) or more, and such award or judgment shall continue
      unsatisfied and in effect for a period of ten (10) consecutive days

                                       36
<PAGE>

      without Tenant's demonstrating, to Landlord's reasonable satisfaction,
      that any insurance policy exists that would cover such award or judgment;

            (xvi) Intentionally Omitted;

            (xvii) if an Event of Default (as defined in the Agreement Regarding
      Leases) occurs under the Agreement Regarding Leases; provided, however,
      that if and to the extent that a default under this clause (xvii) occurs
      and such default arises solely as a result of a default under one (1) or
      more of the other Property Leases (as defined in the Agreement Regarding
      Leases), then, provided that no other independent Event of Default then
      exists under this Lease, such default shall not constitute an Event of
      Default, unless each Facility Mortgagee (if any) holding a Facility
      Mortgage encumbering the Leased Property consents in writing to such
      default's constituting an Event of Default; or

            (xviii) if, on or before the fifty-fifth (55th) day following the
      date hereof, Tenant has either failed to (i) obtain a modification of the
      conditional use permit relating to the Leased Property commonly known as
      Alterra Clare Bridge of North Oaks (the "North Oaks Facility") in
      satisfaction of Tenant's obligations under Paragraph 25(g) or (ii)
      repurchase the North Oaks Facility from Landlord for an aggregate purchase
      price equal to the sum of (x) $10,081,490, plus (y) all out-of-pocket
      costs and expenses reasonably incurred by Landlord (including, without
      limitation, any legal fees and transfer taxes) in connection with such
      repurchase.

      Notwithstanding the foregoing, if any applicable Facility Mortgage
provides for a shorter cure or grace period, or does not require notice to be
given to trigger an event of default thereunder for the same obligation as
described above and provided such obligation is a concurrent obligation of
Tenant hereunder, then the provisions for notice (or lack thereof) and cure
under such Facility Mortgage shall supersede the notice and cure provisions set
forth above, it being acknowledged and agreed that all such payments and
obligations of Tenant hereunder shall be made and performed within such time
periods so as to comply with the terms of the Facility Mortgage.

      (b) Remedies. If any of the Events of Default hereinabove specified shall
occur and be continuing, Landlord shall have and may exercise any one or more of
the following rights and remedies:

            (i) Landlord may, by written Notice thereof to Tenant, terminate
      this Lease as to all but not less than all of the Leased Properties, and,
      peaceably or pursuant to appropriate legal proceedings, re-enter, retake
      and resume possession of all of the Leased Properties for Landlord's own
      account and recover immediately from Tenant any and all Rent and other
      sums and damages due or in existence at the time of such termination,
      including, without limitation: (A) all Rent and other sums, charges,
      payments, costs and expenses agreed and/or required to be paid by Tenant
      to Landlord hereunder; (B) all reasonable costs and expenses of Landlord
      in connection with the recovery of possession of the Leased Properties,
      including reasonable attorneys' fees and court costs; and (C) all costs
      and expenses of Landlord in connection with any reletting or attempted
      reletting of the Leased Properties or any part or parts thereof,
      including, without limitation,

                                       37
<PAGE>

      brokerage fees, reasonable attorneys' fees and the cost of any alterations
      or repairs which may be reasonably required to so relet the Leased
      Properties or any part or parts thereof;

            (ii) If an Event of Default continues uncured for a period of six
      (6) months, Landlord may, by written Notice thereof to Tenant, terminate
      Tenant's option to renew the term this Lease for one (1) or both of the
      Renewal Terms;

            (iii) Landlord may, pursuant to any prior notice required by law,
      and without terminating this Lease, peaceably or pursuant to appropriate
      legal proceedings, re-enter, retake and resume possession of the Leased
      Properties for the account of Tenant, make such alterations of and repairs
      to the Leased Properties as may be reasonably necessary in order to relet
      the same or any part or parts thereof and relet or attempt to relet the
      Leased Properties or any part or parts thereof for such term or terms
      (which may be for a term or terms extending beyond the Term), at such rent
      and upon such other terms and provisions as Landlord, in its reasonable
      discretion, may deem advisable. If Landlord retakes and resumes possession
      of the Leased Properties, it shall use commercially reasonable efforts to
      mitigate any damages it suffered by virtue of such Event of Default.
      Subject to the requirements of any Facility Mortgage, upon any such
      reletting, all rents received by Landlord from such reletting shall be
      applied: (A) first, to the payment of all costs and expenses of recovering
      possession of the Leased Properties; (B) second, to the payment of any
      costs and expenses of such reletting, including brokerage fees, reasonable
      attorneys' fees and the cost of any alterations and repairs reasonably
      required for such reletting; (C) third, to the payment of any
      indebtedness, other than Rent, due hereunder from Tenant to Landlord, and
      to satisfy any Liens encumbering Tenant's leasehold interest; (D) fourth,
      to the payment of all Rent and other sums due and unpaid hereunder with
      respect to the Leased Properties; and (E) fifth, the residue, if any,
      shall be held by Landlord and applied in payment of future Rent as the
      same may become due and payable hereunder. If the rents received from such
      reletting during any period shall be less than that required to be paid
      during that period by Tenant hereunder, then Tenant shall promptly pay any
      such deficiency to Landlord and failing the prompt payment thereof by
      Tenant to Landlord, Landlord shall immediately be entitled to institute
      legal proceedings for the recovery and collection of the same. Landlord
      shall, in addition, be immediately entitled to sue for and otherwise
      recover from Tenant any other damages occasioned by or resulting from any
      abandonment of any of the Leased Properties or other Event of Default
      under this Lease other than a monetary Event of Default. No such re-entry,
      retaking or resumption of possession of any of the Leased Properties by
      Landlord for the account of Tenant shall be construed as an election on
      the part of Landlord to terminate this Lease, unless a Notice of such
      intention shall be given to Tenant or unless the termination of this Lease
      be decreed by a court of competent jurisdiction. Notwithstanding any such
      re-entry and reletting or attempted reletting of any Leased Property or
      any part or parts thereof for the account of Tenant without termination of
      this Lease as provided above, Landlord may at any time thereafter, upon
      Notice to Tenant, elect to terminate this Lease as provided above or
      pursue any other remedy available to Landlord for Tenant's previous and
      continuing Event of Default under this Lease; or

                                       38
<PAGE>

            (iv) Landlord may, without re-entering, retaking or resuming
      possession of the Leased Property, sue for all Rent and all other sums,
      charges, payments, costs and expenses due from Tenant to Landlord
      hereunder either: (A) as they become due under this Lease, taking into
      account that Tenant's right and option to pay the Rent hereunder with
      respect to the Leased Properties on a monthly basis in any particular
      Lease Year is conditioned upon the absence of an Event of Default under
      this Lease; or (B) at Landlord's option, accelerate the maturity and due
      date of the whole or any part of the Rent for the entire then-remaining
      unexpired balance of the Initial Term or the applicable Renewal Term, as
      the case may be (reduced to its present value, applying an interest rate
      of eight percent (8%)) less the present value of the fair market rent for
      the same period, plus all other sums, charges, payments, costs and
      expenses required to be paid by Tenant to Landlord hereunder, including,
      without limitation, damages for breach or default of Tenant's obligations
      hereunder in existence at the time of such acceleration, such that all
      sums due and payable under this Lease shall, following such acceleration,
      be treated as being, and in fact shall be, due and payable in advance as
      of the date of such acceleration. Landlord may then proceed to recover and
      collect all such unpaid Rent and other sums so sued for from Tenant by
      distress, levy, execution or otherwise.

      In addition to the remedies hereinabove specified and enumerated, Landlord
shall have and may exercise the right to invoke any other remedies allowed at
law or in equity as if the remedies of re-entry, unlawful detainer proceedings
and other remedies were not herein provided. Accordingly, the mention in this
Lease of any particular remedy shall not preclude Landlord from having or
exercising any other remedy at law or in equity. Nothing herein contained shall
be construed as precluding Landlord from having or exercising such lawful
remedies as may be and become necessary in order to preserve Landlord's right or
the interest of Landlord in the Leased Properties and in this Lease, even before
the expiration of any notice periods provided for in this Lease, if under the
particular circumstances then existing the allowance of such notice periods will
result in the termination of the rights and estate of Landlord in this Lease and
in any of the Leased Properties.

22. LANDLORD'S DEFAULT; LANDLORD'S RIGHT TO DISPUTE.

      (a) Landlord Default. If Landlord shall default in the performance or
observance of any of its covenants or obligations set forth in this Lease and
such default shall continue for a period of thirty (30) days after Notice
thereof from Tenant to Landlord, or such additional period as may be reasonably
required to correct the same provided Landlord has commenced and is diligently
prosecuting a cure thereof, Tenant may declare the occurrence of a "Landlord
Default" by a second Notice to Landlord. Thereafter, Tenant may, but shall have
no obligation, to cure the same (including, without limitation, by making
payments past due under any Facility Mortgage(s) directly to the applicable
Facility Mortgagee(s)), and, subject to the provisions of Paragraph 22(b),
invoice Landlord for costs and expenses (including reasonable attorneys' fees
and court costs) incurred by Tenant in curing the same, together with interest
thereon from five (5) days following the date Landlord receives Tenant's
invoice, at the Overdue Rate. Tenant shall have no right to terminate this Lease
for any default by Landlord hereunder and no right, for any such default, to
offset or counterclaim against any Rent or other charges due hereunder.

                                       39
<PAGE>

      (b) Landlord's Right to Dispute. If Landlord shall in good faith dispute
the occurrence of any Landlord Default, and Landlord, before the expiration of
the thirty (30) day cure period, shall give Notice thereof to Tenant, setting
forth, in reasonable detail, the basis therefor, Landlord shall have no
obligation with respect to such occurrence or event until a final adverse
determination thereof by a court of competent jurisdiction. Tenant and Landlord
shall in good faith attempt to resolve such dispute and if they fail to do so
within ten (10) days after Landlord's Notice, either may submit the matter for
resolution to a court of competent jurisdiction.

23. CONDEMNATION.

      (a) Complete Taking. If (i) the whole of any of the Leased Properties
shall be taken by Condemnation or (ii) a Condemnation of less than the whole of
any of the Leased Properties renders the affected Leased Property Unsuitable for
its Intended Use, then this Lease shall automatically terminate as to the
affected Leased Property only as of the Date of Taking, subject to the
obligations of Tenant to deliver to Landlord all Awards to which Landlord is
entitled pursuant to the terms of this Lease and to pay such other amounts as
required by Paragraph 23(c) hereof, which obligations shall survive the
termination of this Lease as to such affected Leased Property. Tenant and
Landlord shall seek the Award for their interests in the affected Leased
Property as provided in Paragraph 23(c).

      (b) Partial Taking. If any part of any of the Leased Properties shall be
taken by Condemnation, such that the remaining portion of the affected Leased
Property may continue to be used for its Intended Use, this Lease shall not
terminate or be terminated, and subject to Paragraph 23(d), Tenant shall restore
the remaining portion of the affected Leased Property to the extent necessary to
render it reasonably suitable for its Intended Use and make all repairs to any
related Improvements or Related Personal Property damaged by such taking to the
extent necessary to constitute such Improvements a complete architectural unit
and otherwise in accordance with Legal Requirements.

      (c) Award. All Awards in any Condemnation, either permanent or temporary,
of all or any part of any of the Leased Properties or any easement or any
appurtenance thereto, including severance and consequential damages and change
in grade of any street, shall, after any required repayment of any applicable
Facility Mortgage pursuant to the terms thereof, be the property of and paid to
Landlord, provided that the Award in connection with any partial taking shall be
made available by Landlord to pay or reimburse Tenant for the cost of
restoration or rebuilding. Landlord shall make available to Tenant all or any
portion of the Award to be used to pay for costs of restoration or rebuilding in
connection with any such partial taking. Any such funds shall be held and
disbursed by Escrow Agent in the manner and under the conditions provided in
Paragraph 17. Any surplus which may remain out of any Award after any required
repayment of any applicable Facility Mortgage and any payment or reimbursement
to Tenant of the cost of restoration or rebuilding shall be retained by
Landlord, and the Lease Basis shall be reduced on a dollar-for-dollar basis by
the amount so retained. Notwithstanding the foregoing, any Award made for the
Tenant's leasehold interest in the Leased Property, the loss of Tenant's
business for the remainder of the Term and relocation expenses of Tenant shall
be paid to and be the property of Tenant.

                                       40

      (d) Unavailability of Award. If, in connection with a partial
Condemnation, a Facility Mortgagee refuses to make available (within a
commercially reasonable time in light of the circumstances) for the
reconstruction, repair and restoration of the applicable Facility any portion of
the Award, then, unless Landlord, in Landlord's sole and absolute discretion,
agrees to make available to Tenant funds in an amount equal to the amount of
proceeds so applied by such Facility Mortgagee, Tenant may give a Notice
electing to terminate this Lease as it relates to the applicable Leased
Property. Landlord shall notify Tenant in writing as to whether Landlord intends
to make such funds available and shall deliver such notice to Tenant not later
than ten (10) Business Days after receiving written notice from the applicable
Facility Mortgagee that such Facility Mortgagee has applied or intends to apply
(or has made a final determination not to disburse) the Award (it being
acknowledged and agreed by the parties hereto that if Landlord advances any
funds under this Paragraph 23(d), the Lease Basis will not be increased in
connection with any such funding). Such termination option shall be exercised,
if at all, by termination Notice given during the fifteen (15) Business Day
period after Tenant's receipt of such notice from Landlord (time being of the
essence with respect to the giving of such termination notice by Tenant within
such time period). If Tenant elects under this Paragraph 23(d) to terminate this
Lease as it relates to the applicable Leased Property, such partial termination
shall be effective on the day on which the applicable condemning authority pays
the Award and such funds are actually applied by the applicable Facility
Mortgagee in reduction of the principal amount of the applicable Facility
Mortgage. Upon the effective date of the transactions contemplated by the
termination notice, (i) Tenant shall immediately assign Tenant's rights in and
to any Award relating to such condemnation, and (ii) from and after such
effective date until the Expiration Date, the Rent payable monthly under this
Lease shall be reduced in an amount equal to the Deleted Property Rent
Adjustment, and the applicable Deleted Property shall no longer be considered a
Leased Property for the purposes of this Lease (other than Paragraph 18(f) and
Paragraph 19(c)).

      (e) Notices. Each of Landlord and Tenant further covenants and agrees to
give the other immediate Notice of the actual or threatened commencement of any
Condemnation proceedings and to deliver to the other copies of any and all
papers served in connection with any such proceedings.

24. REPORTS AND STATEMENTS. Tenant shall furnish the following reports and
statements to Landlord during the Term; provided, however, that with respect to
the items listed in clauses (i) through (v) below, Tenant shall be required to
furnish same only if and to the extent such reports are required to be delivered
to any Facility Mortgagee pursuant to the loan documents relating to the
applicable Facility Mortgage, whereupon Tenant shall furnish such reports listed
in clauses (i) through (v) below simultaneously with the delivery of the same to

applicable law or regulations or (y) Tenant's ordinary business practices and
standard resident agreements, if any, require Tenant to maintain the
confidential nature of certain personal information relating to individual
residents living in the applicable Facility, in which case, such protected
information shall be redacted from the material otherwise required to be
delivered hereunder):

            (ii) true and complete copies of a report regarding the compliance

      and Life Safety Code survey reports (excluding, however, correspondence
      which may be subject to any attorney-client privilege);

            (v) such other confirmation as to the licensure and, if applicable,
      Medicare and Medicaid participation of Tenant as Landlord may reasonably
      request from time to time;

            (vi) as soon as available, and in any event within thirty (30) days

      other information with respect to Tenant or the operation of the Leased
      Property required pursuant to any Facility Mortgage or otherwise
      reasonably requested by Landlord.

25. ADDITIONAL COVENANTS OF TENANT.

                                       42
<PAGE>

      (a) Indebtedness of Tenant. Tenant shall not create, incur, assume or
guarantee, or permit to exist, or become or remain liable directly or indirectly
upon, any indebtedness except the following:

            (i) indebtedness of Tenant to Landlord or to Manager under the
      Management Agreement;

            (ii) indebtedness of Tenant for current taxes, assessments,
      governmental charges of levies, to the extent that payment thereof shall
      not at the time be required to be made in accordance with the provisions
      of Paragraph 26;

            (iii) indebtedness of Tenant in respect of judgments or awards (A)
      either (x) which have been in force for less than the applicable appeal
      period and in respect of which execution thereof shall have been stayed
      pending such appeal or review, or (y) which are fully covered by insurance
      payable to Tenant, or (z) which are for an amount not in excess of
      $250,000.00, in the aggregate, at any one time outstanding, and (B) either
      (x) which have been in force for not longer than the applicable appeal
      period, so long as execution is not levied thereunder, or (y) in respect
      of which an appeal or proceedings for review shall at the time be
      prosecuted in good faith in accordance with the provisions of Paragraph
      26, and in respect of which execution thereof shall have been stayed
      pending such appeal or review;

            (iv) unsecured borrowings from any Related Party (other than
      Landlord or its Affiliates) which are by their terms expressly subordinate
      to the payment and performance of Tenant's obligations under this Lease;

            (v) indebtedness for purchase money financing of goods and services
      in an amount not to exceed Fifty Thousand Dollars ($50,000.00), per
      Facility, incurred in the ordinary course of business, provided that any
      such indebtedness in excess of $50,000.00 incurred in the ordinary course
      of business shall be subject to Landlord's consent, which shall not be
      unreasonably withheld, conditioned or delayed; or

            (vi) unsecured trade payables incurred in the ordinary course of
      business.

      (b) Management of Leased Property; Joinder by Manager. Tenant shall not
enter into or permit to exist any management agreement with respect to any of
the Leased Properties, or make any material modification of an approved
management agreement, unless the terms thereof have been previously approved in
writing by Landlord, which approval may be withheld in Landlord's reasonable
discretion; provided, however, that Landlord hereby approves the terms of the
Management Agreement. Subject to the rights of any Facility Mortgagee, all
management fees, payments in connection with any extension of credit and fees
for services provided in connection with the operation of each of the Leased
Properties payable by Tenant to Manager under the Management Agreement are
hereby subordinated to all of the obligations of Tenant due under this Lease,
and Manager's consent to such subordination is evidenced by its joining into
this Lease solely to acknowledge and agree to the subordination and the other
terms and conditions set forth in this Paragraph 25(b). Upon replacement of the
Manager in accordance with the terms of this Lease, Tenant shall, and shall
cause the new Manager of the applicable

                                       43
<PAGE>

Leased Property or Leased Properties to, execute (x) a Manager's Consent and
Subordination of Property Management Agreement, in form and substance reasonably
acceptable to Landlord and the new Manager, which shall provide that any fee
relating to the management or operation of the applicable Leased Property (or
Leased Properties) is and shall at all times remain subordinate to the payments
of Rent hereunder and that such replacement manager shall be subject to the
termination provisions of Paragraph 28 of the Agreement Regarding Leases, and
(y) a Manager's Consent and Subordination of Property Management Agreement, in
form and substance reasonably acceptable to any applicable Facility Mortgagee
and the new Manager, which shall provide that any fee relating to the management
or operation of the applicable Leased Property (or Leased Properties) is and
shall at all times remain subordinate to the payments under any related Facility
Mortgage.

      (c) Intentionally Omitted.

      (d) Capital Additions. Subject to the provisions of Paragraph 10(c) of the
Agreement Regarding Leases, during each Lease Year of the Term, Tenant shall
expend on Capital Additions made to the Facilities, in the aggregate, an amount
at least equal to the Minimum Capital Additions Amount. As used herein, the term
"Minimum Capital Additions Amount" shall mean, with respect to the Facilities,
the product of (i) the number of units contained in the Facilities (in the
aggregate) multiplied by (ii) Four Hundred Dollars ($400) during the first (1st)
year of the Term, as such amount shall be increased on the first day of each
succeeding Lease Year of the Term after the first Lease Year of the Term in
proportion to increases in the Consumer Index, provided that in no event shall
the Minimum Capital Additions Amount be less than the Minimum Capital Additions
Amount for the prior Lease Year. If in any Lease Year Tenant fails to expend the
entire Minimum Capital Additions Amount, as required pursuant to this Paragraph
25(d), prior to the end of such Lease Year, Tenant shall pay any such shortfall
amount to Landlord, which funds shall be deposited into the Capital Additions
Reserve (as defined in the Agreement Regarding Leases) (or a similar account
required in connection with any Facility Mortgage(s)), for expenditure by Tenant
as required herein. If Tenant funds any such shortfall amount to the Capital
Additions Reserve prior to the end of the applicable Lease Year, no default
shall be deemed to have occurred hereunder. Provided no Event of Default exists
hereunder any such escrowed funds shall be disbursed by Landlord from time to
time during the Term, in accordance with the terms and conditions set forth in
Paragraph 10(d) of the Agreement Regarding Leases, to be used in connection with
Capital Additions requiring funds in the applicable Lease Year in excess of the
Minimum Capital Additions Amount, as more particularly described in Paragraph
10(c) and Paragraph 10(d) of the Agreement Regarding Leases. Subject to the
provisions of Paragraph 12(a) of the Agreement Regarding Leases, the Minimum
Capital Additions Amount may be adjusted from time to time based on the
requirements of any Facility Mortgagee, provided any such provisions regarding
the funding of capital replacement reserves under any future Facility Mortgage
shall be in compliance with the requirements of Paragraph 54(b). In addition,
Landlord and Tenant agree to review the Minimum Capital Additions Amount
periodically (but in no event less than annually), to provide for the proper
operation and maintenance of each of the Facilities.

      (e) Capital Additions Reserve. Upon Landlord's written request, or if
Tenant deposits any funds in accordance with Paragraph 25(d), or if otherwise
required by any Facility Mortgagee, Tenant shall establish a reserve fund for
the Minimum Capital Additions Amount

                                       44
<PAGE>

(the "Capital Additions Reserve"), which reserve fund shall be held in
Landlord's name or in the name of the Facility Mortgagee, if applicable, in an
escrow account with a financial institution designated by Landlord or by the
Facility Mortgagee, if applicable. If the Capital Additions Reserve is
established, Tenant shall deposit therein one-twelfth (1/12th) of the Minimum
Capital Additions Amount each month. All moneys deposited into the Capital
Additions Reserve shall be maintained for the payment of, or reimbursement to
Tenant for, Capital Additions Costs (other than with respect to Landlord Capital
Additions). Tenant shall convey, pledge and grant to Landlord or the Facility
Mortgagee, as applicable, a security interest in the Capital Additions Reserve
in order to secure Tenant's obligations to pay Rent and other charges under this
Lease. Tenant shall cooperate with Landlord and the Facility Mortgagee, if
applicable, in connection with perfecting any such security interest.

      (f) Operation of each of the Facilities. Tenant shall operate each of the
Facilities in at least as high a standard of operation as the Facilities are
currently operated as of the date of this Lease.

      (g) North Oaks Zoning Compliance. Tenant shall use its best efforts to
obtain, not later than fifty-five (55) days after the date hereof, (i) a
modification of the conditional use permit relating to the North Oaks Facility
that will reinstate the effectiveness of such conditional use permit and (ii)
consent (in form reasonably satisfactory to Landlord) from the Governmental
Agency granting such conditional use permit to the sale and lease back
transaction contemplated by the Stock Purchase Agreement (as defined in the
Agreement Regarding Leases), as it relates to the North Oaks Facility. If Tenant
fails to obtain the conditional use permit modification and the consent referred
to above in this Paragraph 25(g) on or before the date that is fifty-five (55)
days after the date hereof, then, on the date that is fifty-five (55) days after
the date hereof, Tenant shall purchase from Landlord the North Oaks Facility for
a purchase price equal to the sum of (A) $10,081,490 plus (B) all out-of-pocket
costs and expenses reasonably incurred by Landlord in connection with such
repurchase (including, without limitation, any legal fees and transfer taxes),
time being of the essence with respect to Tenant's obligation to consummate the
repurchase transaction on or before the date that is fifty-five (55) days after
the date hereof. If Tenant consummates the repurchase transaction as set forth
above in this Paragraph 25(g), then from and after the date of the closing of
such sale and repurchase, (1) the North Oaks Facility shall be deleted from the
definition of Leased Property, except with respect to Tenant's obligations under
Paragraph 19(c), and (2) the Lease Basis shall be reduced by $10,081,490.

26. PERMITTED CONTESTS. Tenant shall have the right to contest the amount or
validity of any Legal Requirement, Insurance Requirement, Lien, Imposition,
charge or other claim (collectively, "Claims") as to any of the Leased
Properties, by appropriate legal proceedings, conducted in good faith and with
due diligence, provided that (i) the foregoing shall in no way be construed as
relieving, modifying or extending Tenant's obligation to pay any Claims as
finally determined; (ii) such contest shall not cause Landlord to be in default
under any Facility Mortgage; (iii) no part of the applicable Leased Property nor
any Rent therefrom shall be in any immediate danger of sale, forfeiture,
attachment or loss; and (iv) Tenant shall indemnify and hold harmless Landlord
from and against any cost, claim, damage, penalty or reasonable expense,
including reasonable attorneys' fees, incurred by Landlord in connection
therewith or as a result thereof. Upon Landlord's request, Tenant shall either
(i) provide a bond, title indemnity, endorsement or other assurance reasonably
satisfactory to Landlord that all Claims which may be

                                       45
<PAGE>

assessed against the applicable Leased Property, together with all interest and
penalties thereon, will be paid, or (ii) deposit within the time otherwise
required for payment with the Escrow Agent or another financial institution
reasonably acceptable to Landlord, as security for the payment of such Claims,
an amount sufficient to pay the same, together with interest and penalties in
connection therewith and all Claims which may be assessed against or become a
Claim on or with respect to the applicable Leased Property, or any part thereof,
in connection with any such contest. Tenant shall furnish Landlord with
reasonable evidence of such deposit, title indemnity, endorsement or other
assurance within five (5) Business Days after request therefor. Landlord agrees
to join in such proceedings if required legally to prosecute such contest (and
shall cooperate with Tenant's reasonable requests in connection therewith, at
Tenant's sole cost and expense), provided that Landlord shall not thereby be
subjected to any liability therefor (including, without limitation, for the
payment of any costs or expenses in connection therewith). Tenant shall be
entitled to any refund of any Claims and such charges and penalties or interest
thereon which have been paid by Tenant or paid by Landlord and for which
Landlord has been fully reimbursed by Tenant. If Tenant shall fail (A) to pay
any Claims promptly after such Claim is finally determined (provided no appeal
has been commenced and under applicable law no payment is required to be made
during the pendency of any appeal), (B) to provide security therefor as provided
in this Paragraph 26, or (C) to prosecute any such contest diligently and in
good faith, Landlord may, upon reasonable Notice to Tenant, pay such charges,
together with interest and penalties due with respect thereto, and Tenant shall
reimburse Landlord therefor, upon demand.

27. NOTICES OF COMMENCEMENT OF CONSTRUCTION. If required by the laws of the
Facility State with respect to the related Leased Property or in the event
permitted by the laws of the Facility State with respect to the related Leased
Property and Landlord so requests, upon Tenant giving Notice to Landlord of its
intended construction, and if Tenant reasonably contemplates that construction
of any work on the applicable Leased Property will cost, in the aggregate, Two
Hundred Fifty Thousand Dollars ($250,000.00) or more for such project, prior to
commencement by Tenant of any work on the applicable Leased Property which shall
have been previously permitted by Landlord as provided in this Lease, Tenant
shall record or file a notice of the commencement of such work (the "Notice of
Commencement") in the land records of the county in which such Leased Property
is located, identifying Tenant as the party for whom such work is being
performed, stating such other matters as may be required by applicable law and
requiring the service of copies of all notices, liens or claims of lien upon
Landlord. Any such Notice of Commencement shall clearly reflect that the
interest of Tenant in the applicable Leased Property is that of a leasehold
estate and shall also clearly reflect that the interest of Landlord, as the fee
simple owner of the applicable Leased Property, shall not be subject to
mechanics or materialmen's liens on account of the work which is the subject of
such Notice of Commencement. A copy of any such Notice of Commencement shall be
furnished to and approved by Landlord (in Landlord's reasonable discretion) and
its attorneys prior to the recording or filing thereof, as aforesaid.

28. LIMITATION ON LIABILITY OF LANDLORD AND TENANT. If Tenant is awarded a money
judgment against Landlord, then Tenant's sole recourse for satisfaction of such
judgment shall be limited to execution against the applicable Leased Property.
In no event shall any trustee, stockholder, shareholder, member, manager,
partner, employee, officer or beneficiary of Landlord be personally liable for
the obligations of Landlord hereunder. Except to the extent

                                       46
<PAGE>

expressly provided in the Guaranty and the Lease Guaranty or in the Agreement
Regarding Leases, in no event shall any trustee, shareholder, member, guarantor,
partner, employee, officer or beneficiary of Tenant or any Affiliate of Tenant
be personally liable for any of the obligations of Tenant hereunder.

29. "NET" LEASE/NO IMPAIRMENT.

      (a) "Net" Lease. Landlord and Tenant acknowledge and agree that this Lease
shall be and constitute what is generally referred to as a "triple net" or
"absolute net" lease, such that Tenant shall be obligated hereunder to pay all
costs and expenses howsoever incurred with respect to, and associated with, each
of the Leased Properties and each of the Facilities, including, without
limitation, all Impositions, utility charges, insurance costs, maintenance
costs, replacement costs and repair and restoration expenses (all as more
particularly herein provided).

      (b) No Affect or Impairment. The obligations of Tenant hereunder shall not
be affected or impaired by reason of (a) any damage to, or destruction of, any
of the Leased Properties or any portion thereof, from whatever cause, or any
Condemnation of any of the Leased Properties or any portion thereof (except as
otherwise expressly and specifically provided in Paragraph 17 or Paragraph 23),
(b) the interruption or discontinuation of any service or utility servicing any
of the Leased Properties, (c) the lawful or unlawful prohibition of, or
restriction upon, Tenant's use of the Leased Property, or any portion thereof,
due to the interference with such use by any Person or eviction by paramount
title, except as provided in Paragraph 33, (d) except as provided in Paragraph
22, any claim that Tenant has or might have against Landlord on account of any
breach of warranty or default by Landlord under this Lease or any other
agreement by which Landlord is bound, (e) any bankruptcy, insolvency,
reorganization, composition, readjustment, liquidation, dissolution, winding up
or other proceedings affecting Landlord or any assignee or transferee of
Landlord, (f) the revocation, suspension or non-renewal of any license, permit,
approval or other authorization necessary for the use of any of the Facilities
for its Intended Use, or (g) for any other cause whether similar or dissimilar
to any of the foregoing other than a discharge of Tenant from any such
obligations as a matter of law. Tenant hereby specifically waives all rights,
arising from any occurrence whatsoever, which may now or hereafter be conferred
upon it by law (i) to modify, surrender or terminate this Lease or quit or
surrender any of the Leased Properties or any portion thereof, or (ii) that
would entitle Tenant to any abatement, reduction, suspension or deferment of the
Rent or other sums payable by Tenant hereunder. The obligations of Landlord and
Tenant hereunder shall be separate and independent covenants and agreements and
the Rent and all other sums payable by Tenant hereunder shall continue to be
payable in all events unless otherwise expressly provided herein.

      knowledge, except as permitted or contemplated by this Lease or the
      Facility Mortgage, neither the execution, delivery or performance of this

<PAGE>

            (iii) No Violations of Agreements. Neither the execution, delivery
      or performance of this Lease by Landlord, nor compliance with the terms
      and provisions hereof, will result in any breach of the terms, conditions

32. NO WAIVER. No course of dealing between Landlord and Tenant, or any delay or
omission of Landlord or Tenant to insist upon a strict performance of any term
or condition of this Lease shall be deemed a waiver of any right or remedy that
such party may have, and shall not be deemed a waiver of any subsequent breach
of such term or condition.

33. QUIET ENJOYMENT. Landlord covenants that Tenant, upon paying the Rent and
observing and keeping the covenants, agreements and stipulations of this Lease
on its part to be kept, shall lawfully, peaceably and quietly hold, occupy and
enjoy each of the Leased Properties during the Term without hindrance, ejection
or molestation. Landlord covenants and warrants that it is lawfully seized of
each of the Leased Properties and has good, right and lawful authority to enter
into this Lease for the full term aforesaid, that each of the Leased Properties
is free and clear of all encumbrances that would prevent Landlord from having
such right and authority and that Landlord will put Tenant in actual possession
of each of the Leased Properties on the Commencement Date.

34. INTENTIONALLY OMITTED.

35. SUBORDINATION, NON-DISTURBANCE AND ATTORNMENT. If Landlord places a Facility
Mortgage on any of the Leased Properties, Landlord agrees to cause the Facility
Mortgagee to execute and deliver to Tenant, and Tenant agrees to enter into,
execute and deliver promptly to the Facility Mortgagee, a subordination,
non-disturbance and attornment agreement substantially similar to the form
attached hereto as Exhibit C (the "Subordination Agreement") with any such
Facility Mortgagee, which shall provide, among other things, that if the
Facility Mortgagee or any other Person acquires title to the applicable Leased
Property, so long as no Event of Default has occurred and is continuing
hereunder, Tenant's leasehold estate, possession and occupancy

                                       50
<PAGE>

of such Leased Property shall not be disturbed, and which Subordination
Agreement shall acknowledge that (subject to the foregoing) this Lease, Tenant's
interest hereunder and Tenant's leasehold interest in and to each of the Leased
Properties is junior, inferior, subordinate and subject in right, title,
interest, lien, encumbrance, priority and all other respects to the lien of the
applicable Facility Mortgage. If, within fifteen (15) days following Tenant's
receipt of a written request by Landlord or the holder or proposed holder of any
such Facility Mortgage, Tenant shall fail or refuse or shall have not executed
any such Subordination Agreement, Tenant shall be in breach and default of its
obligation to do so and of this Lease and Landlord shall be entitled thereupon
to exercise any and all remedies available to Landlord pursuant to this Lease or
otherwise provided by law.

36. BROKERS. Each of Landlord and Tenant represent and warrant to the other that
neither of them has engaged or contracted with any person, firm or entity to
serve or act as a broker, agent or finder for the purpose of leasing any of the
Leased Properties, and that no broker's or real estate or other similar
commissions or fees are or shall be due in respect of the transaction
contemplated by this Lease. Each of Landlord and Tenant shall indemnify, defend
and save harmless the other from and against any cost and expense, including
reasonable attorney's fees, incurred by the other as a result of the untruth of
any of the foregoing representations made by it. The terms of this Paragraph 36
shall survive the termination or expiration of this Lease.

37. INVALIDITY. If any provision of this Lease shall be declared invalid or
unenforceable, the remainder of this Lease shall continue in full force and
effect.

38. COUNTERPARTS. This Lease may be executed in two (2) or more counterparts,
which taken together shall be deemed one (1) original.

39. MEMORANDUM OF LEASE. The parties hereto agree not to record this Lease. The
parties agree to execute and to record in the appropriate local registry where
each of the Facilities is located, at Tenant's sole cost and expense, one (1) or
more Memoranda of Lease substantially in the form attached hereto as Exhibit B.

40. CUMULATIVE. All rights and remedies of Landlord and Tenant herein shall be
cumulative and none shall be exclusive of any other or of any rights and
remedies allowed by law.

41. GOVERNING LAW. Except as to matters regarding the internal affairs of
Landlord and issues of or limitations on any personal liability of the members
or managers of Landlord for obligations of Landlord, as to which the laws of the
State of Delaware shall govern, this Lease shall be interpreted, construed,
applied and enforced with respect to each applicable Leased Property in
accordance with the laws of the Facility State in which such Leased Property is
located.

42. SUCCESSORS AND ASSIGNS; RELATIONSHIP. The covenants, terms, conditions,
provisions, and undertakings in this Lease shall extend to and be binding upon
the permitted successors, and assigns of the respective parties hereto, and
shall be construed as covenants running with the land. This Lease creates and
evidences a lease between Landlord and Tenant, and not a partnership, joint
venture, or other type of ownership, inconsistent with a lease, and neither
Landlord nor Tenant shall make any representation to the contrary.

                                       51
<PAGE>

43. ENTIRE AGREEMENT. Except for the terms and conditions of the Agreement
Regarding Leases, this Lease and any exhibits attached hereto, contains the
entire agreement and understanding between the parties with respect to the
subject matter hereof. There are no oral understandings, terms, or conditions,
and neither party has relied upon any representation, express or implied, with
respect to the subject matter hereof not contained in this Lease or the
Agreement Regarding Leases. All prior understandings, terms, or conditions with
respect to the subject matter hereof are deemed merged in this Lease. This Lease
cannot be changed or supplemented orally, but may be modified or amended only by
a written instrument executed by the parties. Any disputes regarding the
interpretation of any portion of this Lease shall not be presumptively construed
against the drafting party.

44. SURVIVAL. Tenant's indemnity obligations herein, including, without
limitation, those set forth in Paragraphs 18(f) and Paragraph 19(c) shall
survive termination of this Lease for two (2) years.

45. ESTOPPEL CERTIFICATES. Each of Landlord and Tenant shall from time to time,
within fifteen (15) Business Days after request by the other and without charge,
give to any person, firm or corporation specified by the requesting party an
estoppel certificate containing such matters with respect to this Lease as may
be reasonably requested. If the estoppel certificate is not returned within such
fifteen (15) Business Day period, such party shall be deemed to have consented
to the information contained therein as if it had executed such Estoppel
Certificate and returned it to the requesting party.

46. TIME. Time is of the essence in every particular of this Lease, including,
without limitation, obligations for the payment of money.

47. CAPTIONS AND HEADINGS. The captions and headings in this Lease have been
inserted herein only as a matter of convenience and for reference and in no way
define, limit or describe the scope or intent of, or otherwise affect, the
provisions of this Lease.

48. WAIVER OF JURY TRIAL. TO THE EXTENT ALLOWED BY APPLICABLE LAW, TENANT AND
LANDLORD HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE THE RIGHT EITHER
OF THEM OR THEIR HEIRS, PERSONAL REPRESENTATIVES, SUCCESSORS OR ASSIGNS MAY HAVE
TO A TRIAL BY JURY WITH RESPECT TO ANY LITIGATION ARISING OUT OF, UNDER OR IN
CONNECTION WITH THIS LEASE OR ANY AGREEMENT CONTEMPLATED TO BE EXECUTED IN
CONJUNCTION HEREWITH, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS
(WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY. THIS PROVISION IS A
MATERIAL INDUCEMENT TO LANDLORD'S ACCEPTING THIS LEASE.

49. SIGNAGE. Tenant shall have the right to install signs containing Tenant's
trade name and such other identification signs on each of the Leased Properties
as are permitted by applicable Legal Requirements. Tenant shall obtain all
governmental permits, licenses and approvals necessary to erect such signs, and
shall maintain such signs in good condition and repair, ordinary wear and tear
excepted (subject to Tenant's obligations under clauses (ii) and (iii) of

                                       52
<PAGE>

Paragraph 8(a)). Tenant shall not remove any identification signs without first
obtaining Landlord's written consent, which shall not be unreasonably withheld
or delayed.

50. GUARANTY. At the time of Tenant's execution of this Lease, Tenant shall
obtain the execution of the guaranty agreement in the form of Exhibit D attached
hereto ("Guaranty") by Guarantor.

51. INTENTIONALLY OMITTED.

52. PUBLIC OFFERING INFORMATION; DELIVERY OF INFORMATION. Tenant specifically
agrees that Landlord (or Landlord's direct or indirect Parent) may include
financial information and information concerning Tenant, Lease Guarantor,
Guarantor and the operation of each of the Leased Properties that does not
violate the confidentiality of the facility-resident relationship and the
physician-resident privilege under applicable laws, in offering memoranda or
prospectuses, or similar publications in connection with syndications, private
placements or public offerings of Landlord's (or Landlord's direct or indirect
Parent's) securities or interests, and any other reporting requirements under
applicable federal and state laws, including those of any successor to Landlord
(or Landlord's direct or indirect Parent). Tenant agrees to provide such other
reasonable information necessary with respect to Tenant, the Facilities, and
each of the Leased Properties to facilitate a private placement or a public
offering or to satisfy the SEC or regulatory disclosure requirements. Tenant
agrees to cause, at Landlord's sole cost and expense, Tenant's independent
accountants to consent to the inclusion of their audit report issued with
respect to such financial statements in any registration statement or other
filing under federal and state laws and to provide the underwriters
participating in any offering of securities or interests of Landlord (or
Landlord's direct or indirect Parent) with a standard accountant's "comfort"
letter with regard to the financial information of Tenant or the Leased
Properties included or incorporated by reference into any prospectus or other
offering document. Tenant also agrees to make available to any underwriter
participating in an offering of Landlord's (or Landlord's direct or indirect
Parent's) securities or interests, and any attorney, accountant or other agent
or representative retained by an underwriter (an "Inspector"), all financial and
other records and pertinent corporate documents of Tenant as shall be reasonably
necessary to enable them to exercise their due diligence responsibility, and
cause Tenant's directors, officers and employees to supply all information
requested by any such Inspector in connection with such offering. Prior to any
submission or circulation of any such offering memoranda, prospectuses or
similar publications, Landlord shall provide to Tenant such documents for the
purpose of reviewing same. Upon request of Landlord, Tenant shall notify
Landlord of any necessary corrections to information Landlord proposes to
publish within a reasonable period of time (not to exceed three (3) Business
Days) after being informed thereof by Landlord.

53. APPRAISAL PROCEDURE. If it becomes necessary to determine the Fair Market
Value of one (1) or more the Facilities for any purpose of this Lease and the
parties cannot agree thereon, such Fair Market Value shall be determined upon
the written demand of either party in accordance with the following procedure:

            (i) The party requesting an appraisal, by Notice given within thirty
      (30) days after the date of the event that requires or permits such
      procedure, shall propose and unilaterally approve an appraiser licensed to
      perform MAI appraisals and experienced in

                                       53
<PAGE>

      the valuation of assisted living, independent living or skilled nursing
      facilities (a "Qualified Appraiser"). The other party, by Notice given
      within fifteen (15) days after receipt of such Notice appointing the first
      Qualified Appraiser, may appoint a second Qualified Appraiser. If the
      other party fails to appoint the second Qualified Appraiser within such
      fifteen (15) day period, such party shall have waived its right to appoint
      a Qualified Appraiser, and the first Qualified Appraiser shall make the
      sole determination of the Fair Market Value.

            (ii) The selected Qualified Appraiser or Appraisers shall thereupon
      determine the Fair Market Value of the applicable Leased Property or
      Leased Properties. Each such Qualified Appraiser shall, within thirty (30)
      days following its appointment, submit its appraisal of such fair market
      value to each of Landlord and Tenant in writing, and if the amounts set
      forth in such appraisals vary by five percent (5%) or less of the greater
      value, the Fair Market Value of the applicable Leased Property or Leased
      Properties shall be determined by calculating the average of the two
      determinations by the two appraisers.

            (iii) If the fair market values set forth in the two appraisals vary
      by more than five percent (5%) of the greater of the two values, the two
      Qualified Appraisers shall select a third Qualified Appraiser within an
      additional fifteen (15) days following the submittal of the last
      appraisal. If the two appraisers are unable to agree upon the appointment
      of a third appraiser within such fifteen (15) day period, either party
      may, upon written notice to the other, request that such appointment be
      made by the then President (or equivalent officer) of the Chapter of the
      American Institute of Real Estate Appraisers in the Facility State for
      each of the applicable Leased Properties, or his or her designee or, if
      there is no such organization or if such individual declines to make such
      appointment, by any state or Federal court of competent jurisdiction for
      the Facility State for each of the applicable Leased Properties.

            (iv) Within twenty (20) days following its selection, the third
      appraiser shall review the two (2) appraisals and select the appraisal
      that it determines most clearly reflects the fair market value. The
      selected fair market value shall then be the Fair Market Value of the
      applicable Leased Property or Leased Properties.

            (v) In connection with the appraisal process, Tenant shall provide
      the appraisers full access during normal business hours to examine the
      applicable Facility or Facilities, the books, records and files of Tenant
      and all agreements, leases and other operating agreements relating to the
      applicable Facility or Facilities. The costs of each party's appraisal
      shall be borne by the selecting party and the cost of the third appraisal
      shall be shared equally. Upon determining such value, the appraisers shall
      promptly notify Landlord and Tenant in writing of such determination. The
      determination of the Qualified Appraisers made in accordance with the
      foregoing provisions shall be final and binding upon the parties, such
      determination may be entered as an award in arbitration in a court of
      competent jurisdiction, and judgment thereon may be entered.

54. FACILITY MORTGAGES.

                                       54
<PAGE>

      (a) Cooperation in Obtaining Facility Mortgages. Tenant agrees, at
Landlord's cost and expense, to cooperate with Landlord's reasonable requests to
assist Landlord in obtaining one (1) or more Facility Mortgage(s) with respect
to Landlord's fee interest in one (1) or more of the Leased Properties. Subject
to the execution of a reasonably satisfactory confidentiality agreement, and
provided there is no violation of (i) any security, health, safety, or
confidentiality requirements of any Governmental Agency or imposed by applicable
law or regulations and/or (ii) Tenant's ordinary business practices and standard
resident agreements, if any requiring Tenant to maintain the confidential nature
of certain personal information relating to individual residents living in the
applicable Facility, Tenant agrees to provide such information as is reasonably
requested by Landlord or any proposed Facility Mortgagee with respect to Tenant,
Guarantor or the operation of the applicable Leased Property or Leased
Properties to facilitate in obtaining such Facility Mortgage.

      (b) Compliance With Facility Mortgages. Tenant agrees to operate each of
the Facilities and to maintain each of the Facilities and all of the Leased
Properties in a manner that complies in all material respects with the terms of
any Facility Mortgage, provided the same do not conflict with the terms of this
Lease (subject to the penultimate sentence of this Paragraph 54(b)). Tenant
shall make all deliveries of information with respect to the applicable Leased
Property available to Tenant and required under such Facility Mortgages and
shall otherwise comply with the operational requirements in such Facility
Mortgages, provided the same do not conflict with the terms of this Lease
(subject to the penultimate sentence of this Paragraph 54(b)), including,
without limitation, complying in all material respects with the insurance
requirements (subject to the proviso in the penultimate sentence of this
Paragraph 54(b)) and the financial reporting requirements. Tenant shall not have
any right to approve the terms of any Facility Mortgage, and Landlord may enter
into any Facility Mortgage as Landlord may determine in Landlord's sole and
absolute discretion; provided, however, that Landlord agrees that the business
terms, provisions and conditions contained in any Facility Mortgage shall be
commercially reasonable in the then current market at the time that such
Facility Mortgage is obtained and shall be reasonably consistent with the then
current standards for similar-type financing transactions affecting similar
types of properties as reflected, generally, in mortgages, deeds of trust and
security deeds encumbering other assisted living and independent living
facilities which are similar to those owned and/or managed by Guarantor or its
direct or indirect subsidiaries (provided, however, that with respect to
assessing whether the insurance requirements under the proposed Facility
Mortgage satisfy the foregoing requirement, the standard set forth in Paragraph
18(a)(xiv) shall govern); provided, further, that in no event shall the terms of
any Facility Mortgage increase the Base Rent payable hereunder or alter the
payment schedule for Base Rent, and Tenant agrees that Tenant's obligation to
comply with the terms of any such Facility Mortgage shall not be deemed to be in
contravention or conflict with the terms of this Lease, even in cases where the
Facility Mortgage imposes obligations that are greater than the obligations of
Tenant under this Lease. Landlord shall deliver to Tenant drafts of all proposed
new Facility Mortgage loan documents at least fifteen (15) Business Days prior
to entering into same.

      (c) Escrow Reserve Accounts Under Facility Mortgages. For purposes of this
Lease, any funds on deposit in any escrow reserve account required under any
Facility Mortgage (other than any principal reserve funds) that were funded by
Tenant in accordance with Tenant's obligations under this Lease shall be deemed
to be the property of Tenant. If during the term,

                                       55
<PAGE>

any Facility Mortgage is refinanced and the terms of the replacement Facility
Mortgage do not require Landlord to establish escrows at the inception thereof,
then any amounts then held in escrow reserve accounts (other than principal
reserve accounts) shall be disbursed to Tenant, and any amounts then held in
principal reserve accounts shall be disbursed to Landlord. Subject to Section
16, at the expiration of the Term, any funds on deposit in any escrow reserve
account (other than any principal reserve account) that were funded by Tenant in
accordance with Tenant's obligations under this Lease shall be promptly returned
to Tenant.

55. ESCROWS HELD BY FACILITY MORTGAGEE. Tenant shall be responsible for funding
the real estate tax, capital improvement reserve account, deferred maintenance
reserve account and other property-related reserve accounts under any Facility
Mortgage to the extent that such reserves are used to fund any of Tenant's
obligations under this Lease; provided, however, that Tenant shall not in any
event be required to fund deposits into any principal repayment reserve account.
Provided no Event of Default has occurred and is continuing, Landlord shall
cooperate with Tenant to make available to Tenant for use in accordance with the
terms of the Facility Mortgage amounts held in escrow by any Facility Mortgagee
or any Facility Mortgage on any of the other Leased Properties, excluding
amounts on deposit in debt service reserve funds and amounts held as tenant
security deposits, for the uses established therefor in accordance with the
terms of the applicable Facility Mortgage (i.e., payment of taxes or insurance
premiums; capital expenditures) and which are required to be performed by Tenant
under this Lease. Tenant shall cooperate with Landlord in requesting the
disbursement of such amounts from the applicable Facility Mortgagee in
accordance with the provisions of the Facility Mortgage, and shall promptly
furnish to Landlord such documents and other evidence requested by the
applicable Facility Mortgagee in connection therewith.

56. SINGLE LEASE. Tenant hereby acknowledges that the agreement between Landlord
and Tenant to treat this Lease as single lease in all respects was and is of
primary importance to Landlord, and Landlord would not have entered into this
Lease without there being such an agreement and such treatment of this Lease.
All rights and obligations under this Lease relating to the Leased Properties
shall apply to each Leased Property and any default under this Lease pertaining
to a single Leased Property or to all of the Leased Properties or any portion
thereof shall be an Event of Default pertaining to all of the Properties and
each of the Leased Properties. Without limiting the generality of the foregoing,
the parties hereto acknowledge that, notwithstanding any references herein to
any individual Leased Property and notwithstanding the possibility that certain
individual Leased Properties may be deleted herefrom pursuant to the express
provisions of this Lease under certain limited circumstances, the parties hereto
expressly intend and agree that this Lease is not divisible and shall be treated
as a single lease for all purposes whatsoever (including, without limitation, in
the context of Tenant's attempted rejection, assumption and/or assignment of
this Lease in any bankruptcy or other insolvency proceeding affecting any
Tenant, in which case the parties hereto intend for such rejection to terminate
this Lease with respect to all of the Leased Properties or such assumption to
apply with respect to all of the Leased Properties, i.e., all but not less than
all of the Leased Properties). This Lease does not constitute, and may not be
enforced or treated as, a separate lease for any individual Leased Property.

             SUBORDINATION, NONDISTURBANCE AND ATTORNMENT AGREEMENT

                         For use with Commercial Leases

THIS SUBORDINATION, NONDISTURBANCE AND ATTORNMENT AGREEMENT ("Agreement") is
made to be effective as of the ___ day of _________________________, 200_,
between _______________________________ ("Lender") and _____________, a Delaware
limited liability company ("Tenant").

                                   BACKGROUND:

Tenant has entered into a lease agreement with _______________________ , a
Delaware limited liability company ("Landlord") dated ____________________,
200_, (the "Lease") relating to the property described in Exhibit A attached to
this Agreement and by this reference made a part of this Agreement (the
"Property"). Lender has made or has committed to make or has purchased a loan to
Landlord in the original principal amount of $__________________ (the "Loan")
secured by a [DEED OF TRUST/MORTGAGE, ASSIGNMENT OF RENTS AND SECURITY
AGREEMENT] filed on ____________, 200_, in the office of the __________________
Clerk/Register of Deeds in Liber _______, Page ____ (the "Mortgage") covering
the Property. Tenant has agreed that the Lease will be subject and subordinate
to the Mortgage held by Lender, provided Tenant is assured of continued use of
the Property under the terms of the Lease.

                                   AGREEMENT:

For and in consideration of the mutual covenants contained in this Agreement,
the sum of Ten Dollars ($10.00) and other good and valuable considerations, the
receipt and sufficiency of which are acknowledged, and notwithstanding anything
in the Lease to the contrary, the parties agree as follows:

1.    SUBORDINATION. The Lease with all rights, options, liens and charges
      created by the Lease is expressly made and will continue to be subject to
      and subordinate in all respects to the terms, conditions, lien, operation
      and effect of the Mortgage and to any renewals, modifications,
      consolidations, replacements and extensions of the Mortgage.

2.    NONDISTURBANCE. If Lender or any other party takes possession of the
      Property or becomes the owner of the Property by foreclosure, conveyance
      in lieu of foreclosure or otherwise ("Successor Landlord"), so long as
      Tenant complies with and performs its obligations under the Lease and no
      event of default has occurred and is continuing under the Lease, then
      Lender, on its own behalf and on behalf of Successor Landlord agrees as
      follows:

                                  Exhibit C-1
<PAGE>

      (a) Successor Landlord will not terminate, impair or disturb the
possession of Tenant.

      (b) The Lease will continue in full force and effect as a direct Lease
between Successor Landlord and Tenant, upon and subject to all of the terms,
covenants and conditions of the Lease, for the balance of the term of the Lease.

3.    MORTGAGE Remedies. Nothing contained in this Agreement will prevent Lender
      from naming Tenant in any foreclosure or other action or proceeding
      initiated by Lender pursuant to the Mortgage to the extent necessary under
      applicable law in order for Lender to avail itself of and complete the
      foreclosure or other remedy.

4.    ATTORNMENT. If Successor Landlord becomes the owner of the Property by
      foreclosure, conveyance in lieu of foreclosure or otherwise, then Tenant
      agrees as follows:

      (c) Tenant will perform and observe its obligations under the Lease.

      (d) Tenant will attorn to and recognize Successor Landlord as the Landlord
under the Lease for the remainder of the term of the Lease, such attornment to
be automatic and self-operative.

      (e) Tenant will execute and deliver upon request of Successor Landlord an
appropriate agreement of attornment to Successor Landlord.

5.    PROTECTION OF SUCCESSOR LANDLORD. Tenant agrees that Successor Landlord
      will not be liable for, subject to or bound by any of the following:

      (f) claims, offsets or defenses which Tenant might have against Landlord;

      (g) acts or omissions of Landlord;

      (h) rent or additional rent which Tenant might have paid for more than
current month;

      (i) any security deposit or other prepaid charge paid to Landlord which
Successor Landlord has not received;

      (j) construction or completion of any improvements for Tenant's use and
occupancy;

      (k) warranties of any nature whatsoever, including any warranties
respecting use, compliance with zoning, hazardous wastes or environmental laws,
Landlord's title, Landlord's authority, habitability, fitness for purpose or
possession; or

      (l) amendments or modifications of the Lease made without its written
consent.

6.    SUCCESSOR LANDLORD EXCULPATION. Tenant will look solely to Successor
      Landlord's interest in the Property for the payment and discharge of any
      obligation or liability imposed upon Successor Landlord under the Lease.

7.    ESTOPPEL. To the best of Tenant's knowledge, there does not exist any
      default, claim, controversy or dispute under the Lease. Tenant has not
      commenced any action nor sent or received any notice to terminate the
      Lease.

8.    NOTICE TO LENDER. Tenant agrees that it will deliver to Lender a copy of
      all notices of default or termination received by it under the terms of
      the Lease.

                                  Exhibit C-2
<PAGE>

9.    ASSIGNMENT TO LENDER. Tenant acknowledges that the Landlord may execute
      and deliver to Lender an assignment of the Lease as security for the Loan
      and Lender may assign the Loan to _____________________. Tenant expressly
      consents to such assignments.

10.   INVALIDITY. If any portion of this Agreement is held invalid or
      inoperative, then all of the remaining portions will remain in full force
      and effect, and, so far as is reasonable and possible, effect will be
      given to the intent manifested by the portion or portions held to be
      invalid or inoperative.

11.   GOVERNING LAW. This Agreement will be governed by and construed in
      accordance with the laws of the State where the Property is located.

            (ii) Any party to this Agreement may change the address to which

                             FORM OF LEASE GUARANTY

      THIS LEASE GUARANTY (this "Guaranty") is made and entered into to be
effective as of October __, 2004 (the "Effective Date"), by ALS PROPERTIES
HOLDING COMPANY, LLC, a Delaware limited liability company ("Guarantor"), in
favor of PSLT-ALS PROPERTIES I, LLC, a Delaware limited liability company
("Landlord").

                                    RECITALS

      WHEREAS, as of the Effective Date, Landlord and ALS Properties Tenant I,
LLC, a Delaware limited liability company, as tenant ("Tenant"), have executed
and entered into that certain Lease Agreement (as the same may be renewed,
extended, amended or modified from time to time, the "Lease"), pertaining to
those certain Leased Properties (as defined in the Lease Agreement);

      WHEREAS, Guarantor is a direct or indirect owner of 100% of the beneficial
ownership interest in Tenant, and Guarantor will derive substantial direct and
indirect benefit from the transactions contemplated by the Lease; and

      WHEREAS, it is a condition to the entering into of the Lease by Landlord
that Guarantor shall have executed and delivered this Guaranty.

      NOW, THEREFORE, in consideration of the foregoing and for other good and
valuable consideration the receipt and sufficiency of which are hereby
acknowledged by Guarantor, and in order to induce Landlord to enter into the
Lease, Guarantor hereby agrees as follows:

   1. GUARANTY. Guarantor hereby unconditionally and irrevocably guarantees (i)
the full and prompt payment of all rent and other sums required to be paid by
Tenant under the Lease, (ii) the full and timely performance of all other terms,
conditions, covenants and obligations of Tenant under the Lease (as same may be
amended, renewed, extended or modified), and (iii) any and all expenses
(including reasonable attorneys' fees and expenses) incurred by Landlord in
enforcing any rights under the Lease or this Guaranty (such obligations,
collectively, are referred to as the "Guaranteed Obligations"). Guarantor agrees
that this Guaranty is a guarantee of payment and performance, not collection,
and that Guarantor is primarily liable and responsible for the payment and
performance of the Guaranteed Obligations. It is not necessary for Landlord, in
order to enforce payment and performance by Guarantor under this Guaranty, first
or contemporaneously to institute suit or exhaust remedies against Tenant or
others liable for any of the Guaranteed Obligations or to enforce rights against
any collateral securing any of it. With the exception of the defense of prior
payment, performance, or compliance by Tenant or Guarantor of the Guaranteed
Obligations which Guarantor is called upon to pay, or the defense that
Landlord's claim against Guarantor hereunder is barred by the applicable statute
of limitations, all defenses of the law of guaranty or suretyship, including,
without limitation, substantive defenses and procedural defenses, are waived and
released by Guarantor to the extent permitted by law. Except as provided in the
preceding sentence, under no circumstances will the liability of Guarantor under
this Guaranty be terminated either with respect to any period of time when the
liability of Tenant under the Lease continues, or with respect to any
circumstances as to which the Guaranteed Obligations have not been fully
discharged by payment, performance or compliance.

                                  Exhibit D-1
<PAGE>

   2. GUARANTY ABSOLUTE. Guarantor guarantees that the Guaranteed Obligations
will be paid and performed strictly in accordance with the terms of the Lease.
The liability and responsibilities of Guarantor under this Guaranty shall be
absolute and unconditional, shall not be subject to any counterclaim, setoff, or
deduction and shall not be released, discharged, affected or impaired by (i) any
change in the time, manner, or place of payment or performance of any of the
Guaranteed Obligations, or any other amendment or waiver of, or any consent to
or departure from, or termination of, the Lease, (ii) any release or discharge
of Tenant in any bankruptcy, receivership or other similar proceedings, (iii)
the impairment, limitation or modification of the liability of Tenant or the
estate of Tenant in bankruptcy or of any remedy for the enforcement of Tenant's
liability under the Lease, resulting from the operation of any present or future
provisions of any bankruptcy code or other statute or from the decision in any
court, the rejection or disaffirmance of the Lease in any such proceedings, or
the assignment or transfer of the Lease by Tenant, (iv) any failure, omission or
delay on the part of Landlord, to enforce, assert or exercise any right, power
or remedy conferred on or available to Landlord in or by the Lease or this
Guaranty, or any action on the part of Landlord granting indulgence or extension
in any form whatsoever or any invalidity, irregularity or unenforceability as to
Tenant of all or any part of the Guaranteed Obligations or any security
therefor, (v) the waiver by Landlord of the performance or observance by Tenant
or Guarantor of any of the agreements, covenants, terms or conditions contained
in the Lease or this Guaranty, (vi) any merger, consolidation, reorganization or
similar transaction involving Tenant even if Tenant ceases to exist as a result
of (and is not the surviving party in) such transaction, (vii) the inability of
Landlord or Tenant to enforce any provision of the Lease for any reason, (viii)
any change in the corporate relationship between Tenant and Guarantor or any
termination of such relationship, (ix) any change in the ownership of all or any
part of the membership interests in Tenant, (x) the inability of Tenant to
perform, or the release of Tenant or Guarantor from the performance of, any
obligation, agreement, covenant, term or condition under the Lease or this
Guaranty by reason of any law, regulation or decree, now or hereafter in effect,
(xi) any merger of the leasehold estate of Tenant with the fee estate or any
other estate in any of the Leased Properties, or (xii) any disability or other
defense of Tenant. Landlord and Tenant, without notice to or consent by
Guarantor, may at any time or times enter into such modifications, extensions,
amendments, or other covenants with respect to the Lease as they may deem
appropriate and Guarantor shall not be released thereby, but shall continue to
be fully liable for the payment and performance of all liabilities, obligations
and duties of Tenant under the Lease as so modified, extended or amended.

   3. REINSTATEMENT. Guarantor further agrees that, if at any time all or any
part of any payment applied to any of the Guaranteed Obligations is or must be
rescinded or returned for any reason whatsoever (including, without limitation,
the insolvency, bankruptcy or reorganization of Guarantor), such Guaranteed
Obligations shall, for the purposes of this Guaranty, to the extent that such
payment is or must be rescinded or returned, be deemed to have continued in
existence, notwithstanding such application, and this Guaranty shall continue to
be effective or be reinstated, as the case may be, as to such Guaranteed
Obligations, all as though such application had not been made.

   4. CERTAIN ACTIONS. Landlord may, from time to time at its discretion and
without notice to Guarantor, take any or all of the following actions: (a)
retain or obtain the primary or secondary obligation of any obligor or obligors,
in addition to Guarantor, with respect to any of

                                  Exhibit D-2
<PAGE>

the Guaranteed Obligations; (b) extend or renew for one or more periods
(regardless of whether longer than the original period), or release or
compromise any obligation of Guarantor hereunder or any obligation of any nature
of any other obligor (including, without limitation, Tenant) with respect to any
of the Guaranteed Obligations; or (c) release or fail to perfect any lien upon
or security interest in, or impair, surrender, release or permit any
substitution or exchange for, all or any part of any property securing any of
the Guaranteed Obligations or any obligation hereunder, or extend or renew for
one or more periods (regardless of whether longer than the original period) or
release or compromise any obligations of any nature of any obligor with respect
to any such property.

   5. WAIVER. To the extent permitted by applicable law, Guarantor hereby
expressly waives: (i) notice of the acceptance of this Guaranty, (ii) except as
otherwise provided in the Lease or this Guaranty, notice of the existence or
creation or non-payment of all or any of the Guaranteed Obligations, (iii)
presentment, demand, notice of dishonor, protest and all other notices
whatsoever except as otherwise provided in the Lease or this Guaranty, and (iv)
all diligence in collection or protection of or realization upon the Guaranteed
Obligations or any part thereof, any obligation hereunder, or any security for
or guaranty of any of the foregoing.

   6. WAIVER OF SUBROGATION. Guarantor hereby waives all rights of subrogation
which it may at any time otherwise have as a result of this Guaranty to the
claims of Landlord against Tenant and all contractual, statutory or common law
rights of reimbursement, contribution or indemnity from Tenant which it may at
any time otherwise have as a result of this Guaranty prior to final payment and
satisfaction of the Guaranteed Obligations.

   7. MISCELLANEOUS.

      (m) Amendments, Etc. No amendment or waiver of any provision of this
Guaranty nor consent to any departure by Guarantor therefrom shall be effective
unless the same shall be in writing and signed by Landlord.

      (o) No Waiver; Remedies. No failure on the part of Landlord to exercise,

exercise of any other right. The remedies herein provided are cumulative and not
exclusive of any other remedies available at law or equity.

      (p) Continuing Guaranty; Transfer of Interest. This Guaranty shall create

and performance in full and satisfaction of the Guaranteed Obligations, (ii) be
binding upon Guarantor and its successors and assigns, and (iii) inure, together
with the rights and remedies of Landlord hereunder, to the benefit of Landlord
and its successors, as permitted under the Lease. Without limiting the
generality of the foregoing clause, if and when Landlord assigns or otherwise
transfers any interest held by it under the Lease to any other person, that

   8. GOVERNING LAW. THIS GUARANTY SHALL BE GOVERNED BY, AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

   9. INDUCEMENT TO LANDLORD. Guarantor acknowledges and agrees that the
execution and delivery of this Guaranty by Guarantor to Landlord has served as a
material inducement to Landlord to execute and deliver the Lease, and Guarantor
further acknowledges and agrees that but for the execution and delivery of this
Guaranty by Guarantor, Landlord would not have executed and delivered the Lease.

   10. INTENTIONALLY DELETED.

   11. INTENTIONALLY DELETED.

   12. SUBMISSION TO JURISDICTION. Guarantor hereby irrevocably submits to the
non-exclusive jurisdiction of any State or Federal court located in New York
County, New York State over any action, suit or proceeding to enforce or defend
any right under this Guaranty or otherwise arising from or relating to this
Guaranty, and Guarantor irrevocably agrees that all claims in respect of any
such action, suit or proceeding may be heard and determined in such court.
Guarantor hereby irrevocably waives, to the fullest extent that it may
effectively do so, the defense of an inconvenient forum or venue to the
maintenance of any such action, suit or proceeding. Guarantor hereby agrees that
a final, non-appealable judgment in any such action, suit or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law.

   13. WAIVER OF JURY TRIAL. Guarantor hereby waives, to the fullest extent
permitted by applicable law, any right to a trial by jury in any action, suit or
proceeding to enforce or defend any rights under this Guaranty or any other
transaction document or any amendment, instrument, document or agreement
delivered or which may in the future be delivered in connection herewith or
arising from or relating to any relationship existing in connection with this
guaranty, and agrees, to the fullest extent permitted by applicable law, that
any such action, suit or proceeding shall be tried before a court and not before
a jury.

   14. COOPERATION, FURTHER ASSURANCES. Guarantor covenants, and agrees to sign,
execute and deliver or cause to be signed, executed and delivered and to do or
make, or to cause

                                  Exhibit D-5
<PAGE>

to be done or make, upon the written request of Landlord, any and all
agreements, instruments, papers, deeds, acts or things, supplemental, confirming
or otherwise, as may be reasonably required by Landlord for the purpose of, or
in connection with, the transaction contemplated hereby. Upon full and final
payment and performance of the Guaranteed Obligations, Landlord agrees to
execute a release for the benefit of Guarantor, in form and content reasonably
satisfactory to Landlord. Notwithstanding anything to the contrary contained
herein, this Guaranty shall survive for a period of twenty four (24) months
after the expiration or earlier termination of the Lease, and Guarantor shall be
liable to Landlord hereunder for any Guaranteed Obligations which arise during
such period and relate to matters which (i) occurred during the term of the
Lease or (ii) Tenant is otherwise required to indemnify Landlord against
pursuant to the terms of the Lease. Except to the extent expressly provided
otherwise in any guaranty or indemnity from Guarantor or its direct or indirect
Parent to Landlord or its Affiliates (each such term as defined in the Lease),
in no event shall any trustee, shareholder, member, guarantor, partner,
employee, officer or beneficiary of Guarantor be personally liable for any of
the obligations of Guarantor hereunder.
