                  AMENDMENT NO. 1 TO MASTER AGREEMENT TO LEASE

      This Amendment No. 1 (hereinafter "Amendment") is made to that certain
Master Agreement to Lease between National Health Investors, Inc. (Landlord) and
National HealthCorp L.P. ("Tenant") dated October 17, 1991, (hereinafter "Master
Lease"), and is entered into effective this 2nd day of June, 1993.

      WHEREAS, pursuant to the terms of the Master Lease, National HealthCorp
L.P. ("NHC") has heretofore agreed to lease certain licensed nursing homes or
retirement centers in 40 geographical locations as identified on Exhibit A to
said Master Lease; and

      WHEREAS, NHC has obtained Certificates of Need to expand the number of
licensed beds in three of said projects, namely the licensed nursing homes in
Hudson and Plant City, Florida, and in Anniston, Alabama; and

      WHEREAS, pursuant to Board resolution of today's date, the Board of
National Health Investors, Inc. ("NHI") has agreed to finance said expansions
and NHC has agreed to pay an increased lease rate thereon, all on the following
terms and conditions; and

      NOW, THEREFORE, IN CONSIDERATION OF THE PREMISES, the parties do hereby
amend the Master Lease by the addition of the following as paragraph 2.07:

      2.07: Expanded Projects. Landlord and Tenant hereby agree that Tenant is
      granted the right to increase the licensed bed capacity at the Leased
      Property located in Hudson and Plant City, Florida, and Anniston, Alabama,
      so long as its expansions are authorized with a certificate of need from
      the appropriate governmental authority and are constructed in a
      substantially similar manner as the existing Leased Property. Landlord
      agrees (at the request of Tenant, and after the issuance of a certificate
      of occupancy on the Expanded Project) to reimburse Tenant for such hard
      costs, including land, construction, landscaping, fixtures or
      appurtenances, as Tenant may have incurred in the expansion of the
      project. At such time as this reimbursement is sought by Tenant, Tenant
      agrees to amend the individual lease for that Leased Property, and to
      increase the base rent thereon by an annual factor equal to 10% times the
      expenses reimbursed by Landlord.

      The parties further agree that the Additional Rent provided for in
      paragraph 2.02 above shall commence on that part of the Leased Property
      expanded pursuant to the terms of this paragraph 2.07 effective the first
      day of January of the calendar year commencing no sooner than six months
      after the date of the commencement of Tenant's lease obligation on the
      expanded property.

      All the rest and residue of the Master Lease and the individual leases on
the Leased Properties located in Hudson and Plant City, Florida, and Anniston,
Alabama, are hereby ratified and affirmed. Executed this the 2nd day of June,
1993.

                  AMENDMENT NO. 2 TO MASTER AGREEMENT TO LEASE

      This Amendment No. 2 (hereinafter "Amendment 2") is made to that certain
Master Agreement to Lease between National Health Investors, Inc. ("Landlord")
and National HealthCare L.P. (formerly National HealthCorp L.P., now known as
"Tenant") dated October 17, 1991, (hereinafter "Master Lease"), and is entered
into effective this 15th day of January, 1996.

      PRELIMINARY STATEMENTS:

      WHEREAS, pursuant to the terms of the Master Lease, National HealthCare
L.P. ("NHC") has heretofore agreed to lease certain licensed nursing homes or
retirement centers in 40 geographical locations as identified on Exhibit A to
said Master Lease; and

      WHEREAS, NHC has agreed to pay as additional rent for these facilities
certain "Assumed Mortgage Debt,"; and

      WHEREAS, certain of the Mortgage Debt has, as of today, been repaid,
defeased, refunded or otherwise changed; and

      WHEREAS, the parties agree to amend the Master Lease to reflect how NHC's
obligations pursuant to the Master Lease are to be handled hereinafter;

      NOW, THEREFORE, IN CONSIDERATION OF THE PREMISES, the parties do hereby
amend the Master Lease by deleting the last sentence of Section 2.02.01 and
substituting in lieu thereof the following:

            In the event that Landlord shall for any reason itself discharge
      (including by prepayment) any Assumed Mortgage Debt, Tenant shall
      thereafter pay the relevant Assumed Mortgage Debt Service Rent as follows:

            a) If the parties cannot otherwise reach agreement, Tenant shall
      thereafter pay the relevant Assumed Mortgage Debt Service Rent directly to
      Landlord in accordance with the original payment terms of the Assumed
      Mortgage Debt so discharged, or by agreement only

            b) At that interest rate as paid by Landlord on any secured or
      unsecured indebtedness, excluding the Line of Credit Note with Bank of
      Tokyo, issued in a transaction occurring within 30 days or more before or
      after the date of Landlord's prepayment with the principal of the Assumed
      Mortgage Debt to be paid as directed by Landlord to Tenant from time to
      time; provided further that in no event shall the principal payments on
      the Assumed Mortgage Debt be greater than the principal payments that were
      assumed at the time of the execution of the original Master Lease. To the
      extent that any prepayment by Landlord has the effect of prepaying debt
      owed by Tenant outside of its Assumed Mortgage Debt obligations under this
      Master Lease, then Tenant agrees to repay NHI said amount by its
      promissory note with a rate of interest as calculated in 2.02.01(b), with
      interest to only accrue during the calendar year in which the prepayment
      occurred and thereafter with principal and interest to be made in 180
      equal monthly payments of principal and interest with said note to balloon
      on December 31, 2006, unless the Master lease is renewed in whole or part,
      in which case said note shall not balloon until December 31, 2011.

            The parties agree to amend the individual leases for the various
      Lease Properties from time to time in order to reflect Landlord's
      designated payment of the principal and rent component pursuant to this
      Section 2.02.01(b).

      All the rest and residue of the Master Lease is hereby ratified and
affirmed this the 15th day of January, 1996.

                  AMENDMENT NO. 3 TO MASTER AGREEMENT TO LEASE

      This Amendment No. 3 (hereinafter "Amendment 3") is made to that certain
Master Agreement to Lease between National Health Investors, Inc. ("Landlord")
and National HealthCare L.P. ("Tenant") dated October 17, 1991, (hereinafter
"Master Lease"), and is entered into effective this 22nd day of July, 1997.

      WHEREAS, pursuant to the terms of the Master Lease, National HealthCare
L.P. ("NHC") has heretofore agreed to lease certain licensed nursing homes or
retirement centers in 43 locations as identified on Exhibit A to said Master
Lease; and

      WHEREAS, NHC has obtained a Certificate of Need to expand the number of
licensed beds or has constructed ancillary space in fourteen of said projects,
namely eight licensed nursing homes in Tennessee -- Athens, Scott, Colonial Hill
Retirement, Milan, Nashville, Pulaski, Sequatchie, Smithville, two in Missouri
-- Joplin and St. Charles, two in South Carolina -- Laurens and Anderson,
Merritt Island in Florida and Glasgow in Kentucky; and

      WHEREAS, pursuant to Board resolution of today's date, the Board of
National Health Investors, Inc. ("NHI") has agreed to finance said expansions
and NHC has agreed to pay an increased lease rate thereon, all on the following
terms and conditions; and

      NOW, THEREFORE, IN CONSIDERATION OF THE PREMISES, the parties do hereby
amend the Master Lease by the addition of the following as paragraph 2.07:

      2.07: Expanded Projects. Landlord and Tenant hereby agree that Tenant is
      granted the right to increase the licensed bed capacity and/or create
      revenue producing ancillary space at the Leased Property located in
      Athens, NHC/Scott in Lawrenceburg, Colonial Hill Retirement in
      Chattanooga, Milan, Nashville, Pulaski, Sequatchie, and Smithville,
      Tennessee; Glasgow, Kentucky; Joplin and St. Charles, Missouri, Laurens
      and Anderson, South Carolina; and Merritt Island, Florida, so long as its
      expansions are either exempt from or authorized with a certificate of need
      from the appropriate governmental authority and are constructed in a
      substantially similar manner as the existing Leased Property. Landlord
      agrees at the request of Tenant from time to time to reimburse Tenant for
      such hard costs, including land, construction, landscaping, fixtures or
      appurtenances, as Tenant may have incurred in the expansion of the
      Project. At such time as this reimbursement is sought by Tenant, Tenant
      agrees to amend the individual lease for that Leased Property, and to
      increase the base rent thereon by an annual factor equal to 9.5% times the
      expenses reimbursed by Landlord.

      The parties further agree that the Additional Rent provided for in
      paragraph 2.02 above shall commence on that part of the Leased Property
      expanded pursuant to the terms of this paragraph 2.07 effective the first
      day of January of 1999, with 1998 as the Base Year.

      All the rest and residue of the Master Lease and the individual lease on
the Leased Properties located in Athens, NHC/Scott in Lawrenceburg, Colonial

Smithville, Tennessee; Glasgow, Kentucky; Joplin and St. Charles, Missouri,
Laurens and Anderson, South Carolina; and Merritt Island, Florida, are hereby
ratified and affirmed. Executed effective this 22nd day of July, 1997.
