A. OPTION(S) TO EXTEND:



Lessor hereby grants to Lessee the option to extend the term of this Lease for One (1) additional Sixty (60) month period(s)
commencing when the prior term expires upon each and all of the following terms and conditions:



(i) In order to exercise an option to extend, Lessee must give written notice of such election to Lessor and Lessor must receive the same at least
6 but not more than 9 months prior to the date that the option period would commence, time being of the essence. If proper notification of the exercise of an option is not given and/or received, such option shall automatically expire.
Options (if there are more than one) may only be exercised consecutively.



(ii) The provisions of paragraph 39, including those relating to Lessees Default set forth in paragraph 39.4 of this Lease, are conditions of this Option.



(iii) Except for the provisions of this Lease granting an option or options
to extend the term, all of the terms and conditions of this Lease except where specifically modified by this option shall apply.



(iv) This Option is personal to the original Lessee, and cannot be assigned or exercised by anyone other than said original Lessee and only while the
original Lessee is in full possession of the Premises and without the intention of thereafter assigning or subletting.



(v) The monthly rent for each month of the option period shall be calculated as follows, using the method(s) indicated below:

| ̈ |  | I. Cost of Living Adjustment(s) (COLA)

a. On (Fill in COLA Dates):
the Base Rent shall be adjusted by the change, if any, from the Base Month specified below, in the Consumer Price Index of the Bureau of Labor
Statistics of the U.S. Department of Labor for (select one): ̈CPI W (Urban Wage Earners and Clerical Workers) or ̈CPI U (All Urban Consumers), for (Fill in Urban Area):

b. The monthly rent payable in accordance with paragraph A.I.a. of this Addendum shall be calculated as
follows: the Base Rent set forth in paragraph 1.5 of the attached Lease, shall be multiplied by a fraction the numerator of which shall be the CPI of the calendar month 2 months prior to the month(s) specified in paragraph A.I.a. above during which
the adjustment is to take effect, and the denominator of which shall be the CPI of the calendar month which is 2 months prior to (select one): ̈the first month of the term of this Lease as set forth in paragraph 1.3 (Base Month) or ̈(Fill in Other Base Month):

The sum so calculated shall constitute the new
monthly rent hereunder, but in no event, shall any such new monthly rent be less than the rent payable for the month immediately preceding the rent adjustment.



c. In the event the compilation and/or publication of the CPI shall be transferred to any other governmental department or bureau or agency or shall be
discontinued, then the index most nearly the same as the CPI shall be used to make such calculation. In the event that the Parties cannot agree on such alternative index, then the matter shall be submitted for decision to the American Arbitration
Association in accordance with the then rules of said Association and the decision of the arbitrators shall be binding upon the parties. The cost of said Arbitration shall be paid equally by the Parties.

|x |  | II. Market Rental Value Adjustment(s) (MRV)



a. On (Fill in MRV
Adjustment Date(s)) November 1, 2009 the Base Rent shall be adjusted to the Market Rental Value of the property as follows:



1) Four months prior to each Market Rental Value Adjustment Date described above, the Parties shall attempt to agree upon what the new MRV will be on the
adjustment date. If agreement cannot be reached, within thirty days, then:



(a) Lessor and Lessee shall immediately appoint a mutually acceptable appraiser or broker to establish the new MRV within the next 30 days. Any associated costs will be split equally between the Parties, or



(b) Both Lessor and Lessee shall each immediately make a
reasonable determination of the MRV and submit such determination, in writing, to arbitration in accordance with the following provisions:



(i) Within 15 days thereafter, Lessor and Lessee shall each select an ̈appraiser or ̈broker (Consultant - check one) of their choice to act as an arbitrator. The two
arbitrators so appointed shall immediately select a third mutually acceptable Consultant to act as a third arbitrator.



(ii) The 3 arbitrators shall within 30 days of the appointment of the third arbitrator reach a decision as to what the actual MRV for the Premises is,
and whether Lessors or Lessees submitted MRV is the closest thereto. The decision of a majority of the arbitrators shall be binding on the Parties. The submitted MRV which is determined to be the closest to the actual MRV shall
thereafter be used by the Parties.

(iii) If either of the Parties fails to appoint an arbitrator within the specified 15 days, the
arbitrator timely appointed by one of them shall reach a decision on his or her own, and said decision shall be binding on the Parties.
