         equal monthly installments."

         months and on January 1st of each successive calendar year until the
         Term Expiration Date or date of earlier termination of this Lease as
         provided herein."

         5. Payments in the event of a Rent Adjustment. Section 4.2 of the Lease
is hereby deleted and the following inserted in lieu thereof:

                  "4.2 Payments in the event of Rent Adjustment. Base Rent shall
         be adjusted on January 1, 2006, and each January 1 thereafter
         throughout the Term of this Lease. In the event this Lease provides for
         adjustment of the Base Rent on any basis that requires a determination
         of Base Rent which cannot be made on or before the due date of the
         first installment of Base Rent following the Adjustment Date, Lessee
         shall continue to pay the Base Rent at the rate previously in effect
         until Lessor gives Lessee Notice of its determination of the adjusted
         Base Rent. Upon such determination, the Base Rent shall be
         retroactively adjusted as of the Adjustment Date. On or before the
         second (2nd) Payment Date for Base Rent following receipt by Lessee of
         Lessors' Notice of the adjustment, Lessee shall make an additional
         payment of Base Rent in such amount as will bring the Base Rent, as
         adjusted, current on or before such (2nd) Payment Date, plus interest
         on the amount of such additional payment (i.e. the difference between
         the monthly installment of Base Rent before and after the increase as
         of the Adjustment Date, divided by thirty (30) and


3
<PAGE>

         multiplied by the number of days between the Adjustment Date and the
         date of payment by Lessee) at the Prime Rate from the Adjustment Date
         through the date of such additional payment, and thereafter Lessee
         shall pay the adjusted Base Rent in correspondingly adjusted monthly
         installments until the Base Rent is next adjusted as required herein.
         This Section 4.2 shall survive the expiration or termination of this
         Lease with respect to any adjustment which is not known or fully paid
         as of the date of the expiration or termination.

                  The reference to "Additional Rent" in the definition of "Rent"
         under Section 1.3 and in Section 4.3, or elsewhere in this Lease are
         hereby deleted, and Exhibit C is hereby deleted and no longer a part of
         this Lease."

         6. General Insurance Requirements. Article 11 of the Lease is hereby
deleted and the following inserted in lieu thereof:


                  "11.1 General Insurance Requirements. Lessee shall keep the
         Leased Properties, and all property located in or on the Leased
         Properties, including any personal property of Lessors and Lessee's
         Personal Property, insured with insurance meeting the following
         requirements: (a) all insurance shall be written by companies
         authorized to do insurance business in the applicable States and having
         a rating classification of not less than A- and a financial size
         category of "Class VII" or larger, according to the then most recent
         issue of Best's Key Rating Guide; (b) all policies must name Lessors as
         an additional insured, and name as an additional insured any Facility
         Mortgagee by way of a standard form of mortgagee's loss payable
         endorsement in use in the applicable States and in accordance with any
         such other requirements as may be established by such Facility
         Mortgagee; (c) casualty losses must be payable to Lessors or Lessee as
         provided in Article 12, and loss adjustments shall require the written
         consent of Lessors, any Facility Mortgagee, and, provided no Event of
         Default has occurred and is continuing at the time, Lessee, which
         consent shall not be unreasonably withheld by either Lessors or Lessee;
         (d) each insurer must agree that it will give Lessors and any Facility
         Mortgagee at least thirty (30) days written notice before its policy
         shall be altered, allowed to expire or canceled; (e) the amount of any
         deductible or retention must be approved by Lessors prior to the
         issuance of any policy, which approval will not be unreasonably
         withheld, conditioned or delayed; and (f) the form of all policies
         shall be approved by Lessors and any existing Facility Mortgagee, whose
         approval shall not unreasonably be withheld, conditioned or delayed,
         provided that such policies conform to the requirements of this Article
         11. Notwithstanding the foregoing, Lessee may obtain so-called
         "umbrella" policies, comprehensive liability policies and professional


4
<PAGE>

         liability policies of insurance from non-admitted surplus line carriers
         acceptable to Lessors.


                  11.2 Risks to be Insured. The policies covering the Leased
         Properties and Lessee's Personal Property shall insure against the
         following risks:

                           11.2.1 Loss or damage by fire, vandalism and
         malicious mischief, earthquake, extended coverage perils commonly known
         as "Special Risk," and all physical loss perils normally included in
         such Special Risk insurance, including but not limited to sprinkler
         leakage, in an amount not less than one hundred percent (100%) of
         Replacement Cost (provided that earthquake coverage may have a sublimit
         coverage of $5,000,000.00);

                           11.2.2 Loss or damage by explosion of steam boilers,
         pressure vessels or similar apparatus in such amounts as may be
         required by Lessors from time to time;

                           11.2.3 Business interruption insurance or a blanket
         earnings and expense coverage endorsement covering risk of loss during
         reconstruction necessitated by the occurrence of any of the hazards
         described in Sections 11.2.1 or 11.2.2 (but in no event for a period
         less than twelve (12) months) in an amount sufficient to prevent
         Lessors and Lessee from becoming a co-insurer;

                           11.2.4 Claims for personal injury or property damage
         under a policy of commercial general public liability insurance with a
         combined single limit per occurrence in respect of bodily injury and
         death and property damage of One Million Dollars ($1,000,000.00), and
         an aggregate limitation of Three Million Dollars ($3,000,000.00), with
         a minimum One Million Dollar ($1,000,000.00) excess policy, which
         insurance shall insure Lessee's contractual liability to Lessors under
         the indemnity provisions of Article 18 of this Lease, and if written on
         a "claims-made" basis, Lessee 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 Lessors in the event such policy is canceled or not
         renewed for any reason whatsoever, or by obtaining "tail" insurance
         coverage providing coverage for a period of at least three (3) years
         beyond the expiration of the Term;

                           11.2.5 Claims arising out of malpractice in an amount
         of not less than Two Million Dollars ($2,000,000.00) for each person
         and for each occurrence and, if written on a "claims-made" basis,
         Lessee shall also provide continuous liability coverage for claims
         during the Term either


5
<PAGE>

         by obtaining an endorsement providing for an extended reporting period
         reasonably acceptable to Lessors in the event such policy is canceled
         or not renewed for any reason whatsoever, or by obtaining "tail"
         insurance coverage providing coverage for a period of at least three
         (3) years beyond the expiration of the Term;

                           11.2.6 Flood (with respect to any portions of the
         Leased Properties located in whole or in party within a designated
         flood plain area) and such other hazards and in such amounts as may be
         customary for comparable properties in the area up to the maximum limit
         that can be obtained under the Federal Flood Insurance Program;

                           11.2.7 During such time as Lessee is constructing any
         improvements, (i) workers compensation insurance and employers'
         liability insurance covering all persons employed in connection with
         the improvements in statutory limits, (ii) builder's risk insurance,
         completed value form, covering all physical loss, in an amount
         satisfactory to Lessors, and (iii) such other insurance, in such
         amounts, as Lessors deem necessary to protect Lessors' interest in the
         Leased Properties from any act or omission of Lessee's contractors or
         subcontractors, and certificates of insurance evidencing such coverage,
         in form satisfactory to Lessors, shall be presented to Lessors prior to
         the commencement of construction of such improvements;

                           11.2.8 Primary automobile liability insurance with
         limits of One Million Dollars ($1,000,000.00) per occurrence each for
         owned and non-owned hired vehicles.

                  11.3 Payment of Premiums; Copies of Policies; Certificates.
         Lessee shall pay when due all of the premiums for the insurance
         required by this Lease, and shall deliver to Lessors and to any
         Facility Mortgagee requesting such evidence, certificates of insurance
         in form satisfactory to Lessors and such Facility Mortgagee.
         Satisfactory evidence of insurance required by this Lease or
         certificates thereof shall be delivered to Lessors prior to their
         effective date (and, with respect to any renewal policy, Lessee will
         use commercially reasonable efforts to provide the same within twenty
         (20) days but in all events not less than five (5) Business Days prior
         to the expiration of the existing policy) with copies of such policies
         to be provided as available, and in the event of the failure of Lessee
         either to carry the required insurance or pay the premiums therefor, or
         to deliver copies of policies or certificates to Lessors as required,
         Lessors shall be entitled, but shall have no obligation, to obtain such
         insurance an pay the premiums therefor when due, which premiums shall
         be repayable to Lessors upon written demand therefor as Additional
         Charges which Lessee shall be deemed to and does hereby agree to pay.



6
<PAGE>

                  11.4 Premiums Deposits. If any provision of a Facility
         Mortgage requires deposits of premiums for insurance to be made with
         the Facility Mortgagee, Lessee shall pay to Lessors monthly the amounts
         required and Lessors shall transfer such amounts to the Facility
         Mortgagee, unless, pursuant to written direction by Lessors, Lessee
         makes such deposits directly with the Facility Mortgagee.

                  11.5 Umbrella Policies. If Lessee chooses to carry umbrella
         liability coverage to obtain the limits of liability required under
         this Lease, the umbrella policies must provide coverage in the same
         manner as the primary commercial general liability policy and must
         contain no exclusions in addition to, or limitations materially
         different than, those of the primary policy.

                  11.6 Additional Insurance. In addition to the insurance
         described above, Lessee shall maintain such insurance as may be
         required from time to time by any Facility Mortgagee, and shall at all
         times comply with all laws with respect to worker's compensation
         insurance coverage.

                  11.7 No Liability; Waiver of Subrogation. Lessors shall have
         no liability to Lessee, and, provided Lessee provides the insurance
         required of it by this Lease, Lessee shall have no liability to
         Lessors, regardless of the cause, for any loss or expense resulting
         from or in connection with damages to or the destruction or other loss
         of any Leased Property or Lessee's Personal Property, and neither party
         will have any right or claim against the other for any such loss or
         expense by way of subrogation. Each insurance policy carried by either
         party covering any of the Leased Properties and Lessee's Personal
         Property, including without limitation, contents, fire and casualty
         insurance, shall contain an express waiver of any right of subrogation
         on the party of the insurer against the other party. Lessee shall pay
         any additional costs or charges for obtaining such waiver.

                  11.8 Increase in Limits. From time to time, but not more often
         than once every two (2) years, in the event that Lessors shall
         reasonably determine that the limits of the commercial general
         liability insurance then carried are insufficient, Lessors shall give
         Lessee Notice of acceptable increased limits for such insurance to be
         carried; and Lessee shall then obtain and maintain such insurance with
         such increased limits unless and until further increase as permitted
         under the provisions of this Section. Lessors' determination of
         increased limits shall be accompanied by a description of the basis for
         such determination.

                  11.9 Blanket Policy. Any insurance required by this Lease may
         be provided by so-called blanket policies of insurance carried by
         Lessee, provided, however, that the coverage afforded Lessors thereby
         may not


7
<PAGE>

         thereby be less than or materially different from that which would be
         provided by a separate policies meeting the requirements of this Lease,
         and provided further that such policies meet the requirements of all
         Facility Mortgages.

                  11.10    No Separate Insurance.

                           11.10.1 Lessee shall not on its own initiative or
         pursuant to the request or requirement of any third party, take out
         separate insurance concurrent in form or contributing in the event of
         loss with that required by this Lease, to be furnished by, or which may
         be reasonably be required to be furnished by, Lessee, or increase the
         amount of any then existing insurance by securing an additional policy
         or additional policies, unless all parties having an insurable interest
         in the subject matter of the insurance, including in all cases Lessors
         and all Facility Mortgagees, are named therein as additional insureds,
         and losses are payable thereunder in the same manner as losses are
         payable under this Lease.

                           11.10.2 Nothing herein shall prohibit Lessee, upon
         Notice to Lessors, from (i) securing insurance required to be carried
         hereby with higher limits of liability than required in this Lease, or
         (ii) securing insurance against risks not required to be insured
         pursuant to this Lease, and as to such insurance, Lessors and any
         Facility Mortgagee need not be included therein as additional insureds,
         nor must losses thereunder be payable in the same manner as losses are
         payable under this Lease, except to the extent required to avoid a
         default under a Facility Mortgage or any other encumbrance.

                           11.10.3 Lessor acknowledges that the liability
         insurance coverage and the malpractice insurance coverage required
         pursuant to Sections 11.2.4 and 11.2.5 of the Lease, are currently
         unavailable generally in the nursing home industry at commercially
         affordable rates and that Lessee currently maintains and has in place
         general liability and malpractice insurance with single limit coverage
         of Two Hundred Fifty Thousand Dollars ($250,000.00) per occurrence and
         Five Hundred Thousand Dollars ($500,000.00) cumulative, with a
         deductible of Twenty Five Thousand Dollars ($25,000.00). Lessor hereby
         agrees that, the provisions of Sections 11.2.4 and 11.2.5 of the Lease
         to the contrary notwithstanding, until such time as the insurance
         coverage required therein is generally available in the nursing home
         industry at commercially affordable rates, Lessee shall not be required
         to obtain the coverages required therein. Lessee shall not be deemed to
         be in default of the provisions of Section 11 of the Leases as a result
         thereof. Lessee shall provide Lessor, on an annual basis, information
         from its insurance carrier and from comparable insurance carriers of
         the costs of insurance

         premiums to meet Lessor's insurance requirements. At such time as the
         premium amounts for required coverage quoted in this Article are
         commercially affordable, Lessee shall immediately purchase any and all
         insurance policies necessary to meet the requirements of Sections
         11.2.4 and 11.2.5 of the Lease. This provision does not relieve Lessee
         from its agreement of indemnity under Article 18 of the Lease (or
         elsewhere in this Lease) nor does it modify the provisions thereof.
         Notwithstanding the foregoing, Lessee acknowledges and agrees that
         Lessor shall have the right to withhold its consent to any proposed
         Permitted Assignment unless the permitted assignee agrees to provide
         the insurance coverage required by the provisions of Sections 11.2.4
         and 11.2.5 of the Lease."

         7. Article 23. An Article 23 shall be inserted into the Lease and
provide as follows:

                  "23.1 Minimum Qualified Capital Expenditures. Each Lease Year,
         Lessee shall expend with respect to each Leased Facility at least Three
         Hundred Fifty Dollars ($350.00) and NO/100 per licensed bed for
         Qualified Capital Expenditures to improve the applicable Facility,
         which amount shall be increased each Lease Year, beginning the January
         1, 2007 Lease Year, in proportion to increases in the CPI from the
         Commencement Date to the commencement of each such Lease Year ("Minimum
         Qualified Capital Expenditures"). If Lessee expends with respect to any
         Facility more than the Minimum Qualified Capital Expenditures in any
         Lease Year, the excess Minimum Qualified Capital Expenditures shall be
         credited against Lessee's Minimum Qualified Capital Expenditures
         required with respect to such Facility for the next Lease Year, and if
         the amount of the credit exceeds Lessee's Minimum Qualified Capital
         Expenditures required with respect to such Facility for the next Lease
         Year, such excess shall be credited against Lessee's Minimum Qualified
         Capital Expenditures required with respect to such Facility for the
         following Lease Years. At least annually, at the request of Lessors,
         Lessors and Lessee shall review the capital expenditures budgets and
         reasonably agree on modifications, if any, required by changed
         circumstances and the changed conditions of the Leased Properties."

         8. Execution and Counterparts. This Amendment may be executed in any
number of counterparts, each of which, when so executed and delivered, shall be
deemed to be an original, but when taken together shall constitute one and the
same Amendment.

         9. Headings. Section headings used in this Amendment are for
convenience of reference only and shall not affect the construction of the
Amendment.

         10. Enforceability of Lease. Except as expressly and specifically set
forth herein, the Lease remains unmodified and in full force and effect. In the
event of any

discrepancy between Lease and this Amendment, the terms and conditions of this
Amendment will control and the Lease is deemed amended to conform hereto.
