F.Landlord and Tenant desire to make other modifications to the Master Lease as set forth in this 6th Amendment.

NOW, THEREFORE, IN CONSIDERATION OF THE PREMISES, the parties do hereby amend the Master Lease as follows:

1.Effective Date of Certain Provisions. This 6th Amendment becomes a part of the Master Lease as of December 26, 2012. The modifications to the Master Lease made in Sections 2, 4, 5, and 6 below shall take effect on the date (herein the “Effective Date”) which is the date on which NHC through its designated affiliates closes the purchase of the Sale Facilities.

2.Modification of "Leased Property". As of the date the sale of the Sale Facilities closes, the phrase “Leased Property,” as found and used in the Master Lease, shall no longer include any of the Sale Facilities, except as expressly provided in this 6th Amendment. Exhibit A to the Master Lease and Schedule A-1 to the 5th Amendment shall be replaced with a revised list of the remaining Leased Property to be attached hereto as Schedule A-1. As of the Effective Date, each Short Form Operating Lease between Landlord and Tenant for any of the Sale Facilities shall terminate. As of the Effective Date, the defined terms “Land,” “Improvements,” “Appurtenances,” and “Fixtures” shall not include any property interests which is a part of any of the Sale Facilities. Upon the conveyance of the Sale Facilities to Tenant, Landlord shall have no continuing obligations to Tenant under the Master Lease with respect to any of the Sale Facilities.

3.Term. Section 1.03 of the Master Lease is hereby amended to acknowledge that Tenant hereby, and as of the date of this 6th Amendment, elects to extend the Term through the Third Renewal Term (as allowed by the 5th Amendment) at the same Base Rent as determined under the provisions of Paragraph 4 below. The Third Renewal Term extends the Term of the Master Lease through December 31, 2026. As provided in the 5th Amendment, Tenant may elect hereafter to further extend the Term of the Master Lease for the Fourth Renewal Term and

The Fifth Renewal Term. The election to extend the Term of the Master Lease through the Third Renewal Term may not be rescinded hereafter by Tenant for any reason other than Landlord’s default in failing to convey the Sales Facilities. If due to Landlord’s default in failing to convey the Sales Facilities, the election to extend the Master Lease is rescinded, Tenant shall have the option to extend the term of the Master Lease for the Third Renewal Term as provided in the Fifth Amendment.

4.Base Rent. Section 2.01.01 of the Master Lease is hereby amended to acknowledge that, as provided in the 5th Amendment, Base Rent due under the Master Lease is currently in the annual amount of Thirty-Three Million Seven Hundred Thousand and No/100 Dollars ($33,700,000.00). Upon the sale of all of the Sale Facilities to Tenant and not less than all of the Sale Facilities, and effective on the Effective Date, Base Rent shall be reduced to equal Thirty Million Seven Hundred Fifty Thousand and No/100 Dollars ($30,750,000.00) per year through the Lease Year ending December 31, 3026. Base Rent shall be paid in equal monthly installments. Base Rent for the Fourth Renewal Term and the Fifth Renewal Term, if applicable, shall be the fair market value base rent as negotiated in the future by Landlord and Tenant. If the Effective Date is later than January 1, 2014, annual Base Rent for the 2014 Lease Year shall remain at $33,700,000.00 through the day preceding the Effective Date, and shall be paid monthly in advance and prorated for any period shorter than a full calendar month. The Base Rent after the sale of the Sale Facilities shall be allocated as set out on Schedule A-2 attached hereto.

5.Percentage Rent. In addition to Base Rent, Tenant shall continue to pay Percentage Rent under Section 2.06 of the Master Lease as amended by the 5th Amendment and as further amended hereby.

(a)With respect to the Sale Facilities only, Percentage Rent for the 2013 Lease Year shall be due and calculated based upon the Gross Revenue of each of the Sale Facilities for the eight (8) month period beginning January 1, 2013 and ending August 31, 2013. For each of the Sales Facilities that Gross Revenue amount shall be compared to 8/12 of the 2007 Gross Revenue for the respective Sale Facility set forth on Schedule A-3. Tenant shall pay to Landlord on or before September 30, 2013, any Percentage Rent due for 2013 on the Sales Facilities, after Landlord’s giving credit for any estimated 2013 payments received by Landlord. For the other Lease Property, Percentage Rent for the 2013 Lease Year shall be paid as required by the Master Lease. Percentage Rent due with respect to the Lease Year ending December 31, 2013 shall be paid in estimated monthly installments during 2013 as provided in Section 2.06.03 of the Master Lease with all Gross Revenues (for both the Sale Facilities and for the remaining Leased Property) to be certified by Tenant and payment adjustment made, if required, in accordance with Sections 2.06.02 and 2.06.03 of the Master Lease.

(b)With respect to Percentage Rent to be paid for the full Lease Year commencing January 1, 2014 and all subsequent Lease Years, the calculation of Gross Revenues shall not include, for both the year in question and the January 1, 2007 through December 31, 2007 base year, any revenues of the Sale Facilities. The Gross Revenue for each Leased Property for the Lease Year ending December 31, 2007 is set out on Schedule A-3, attached hereto.

(a)Notwithstanding the fact that the Sale Facilities are not included within the meaning of the term “Leased Property” after the date of conveyance of the Sale Facilities, Tenant shall remain liable for performing and meeting all obligations under the Master Lease with respect to the Sale Facilities accruing for any period prior to August 29, 2013. Tenant hereby agrees to defend, indemnify and to hold Landlord harmless from and against any loss, liability, claim, damages (including consequential damages), and cost and expense (including attorney’s fees) arising from Tenant’s not having observed or performed any provision of the Master Lease with respect to any of the Sale Facilities.

(b)All indemnity provisions contained in the Master Lease in favor of Landlord, including, but not limited to, the indemnity provisions of Sections 5.01 and 7.02 thereof, shall continue in effect and shall protect Landlord from any matter relating to any of the Sale Facilities, regardless of the time such matter or claim was first asserted against Landlord or became known to Tenant.

(c)Until all applicable statute of limitation periods have passed, Tenant shall continue to include Landlord as an insured with respect to all insurance coverage for any of the Sale Facilities in accordance with the provisions of Section 4.02 of the Master Lease if such insurance coverage is provided on a claims made basis.

7.Non-Compete Provisions. Tenant acknowledges that if Tenant does not elect to exercise its options to extend the Term of the Master Lease for the Fourth Renewal Term or the Fifth Renewal Term, Landlord will need to sell the Leased Properties or find a new operator to lease the Leased Properties. The then market value of the Leased Properties may be influenced by the existence of competing senior housing facilities, as defined herein, located in the proximity of the Leased Facilities. In consideration of Landlord’s lease of the Leased Properties to Tenant, Tenant agrees to the following non-compete provisions:

(a)Except as specifically permitted below, Tenant agrees that during the last five (5) years of the Term of the Master Lease, neither Tenant nor any subsidiary or other affiliated entity of Tenant or any company under common ownership, management or control with Tenant, shall own, acquire, build, construct, lease, manage or operate a Competing Facility, as defined herein, located within the same county as any of the Leased Properties. This non-compete provision shall not apply if either (i) the Competing Facility was in operation or under actual construction by December 31, 2021 or any later date which is five (5) years and one day prior to the end of the Term if the Term has been extended beyond December 31, 2026 (such date is referred to as the “Allowed Pre-existing Facility Determination Date”); or (ii) any Competing Facility located in a county in which as of the Allowed Pre-existing Facility Determination Date, Tenant owns a nursing home, assisted living or senior living center in addition to the center operated by Tenant on the Leased Property in such county; or (iii) regarding an intended project, one for which on the Allowed Pre-existing Facility Determination Date a Certificate of Need has been issued, if required, for such intended project.

(b)As used herein, Competing Facility means any licensed skilled nursing center or licensed skilled and licensed intermediate care nursing center.

(c)In the event Tenant should breach these non-compete provisions, Tenant may be permanently enjoined from doing so. In the event of any suit to enforce the non-compete provisions, if Landlord is granted any relief against Tenant, Tenant shall be liable to Landlord for all of Landlord’s court costs, expenses and legal fees incurred in seeking to enforce the provisions of this non-compete provision.
