W I T N E S S E T H:


Seller and Purchaser
entered into that certain Purchase and Sale Agreement and Escrow Instructions, dated as of August 21, 2015 as amended and assigned
(the “Purchase Agreement”), pursuant to which Seller agreed to sell and Purchaser agreed to purchase, all of
Seller’s respective right, title and interest in and to the Property (as defined in the Purchase Agreement);


WHEREAS, Seller agreed
in accordance with Article 28 of the Purchase Agreement to post a Holdback (as defined in the Purchase Agreement) with Escrow Holder
in an aggregate amount of ONE MILLION AND 00/100 DOLLARS ($1,000,000.00); and


WHEREAS, Escrow Holder
is willing to hold the Holdback in escrow on the terms and conditions hereinafter set forth.


NOW, THEREFORE, the
parties hereto agree as follows:


1.              
All capitalized terms used herein, but not otherwise defined herein, shall have the meanings ascribed to such terms in the
Purchase Agreement.




    1 


     


    

 


2.              
Escrow Holder hereby acknowledges receipt of the Holdback to be held in escrow in accordance with the terms and conditions
of this Agreement.


(a)                                
Escrow Holder shall hold the Holdback, together with all interest earned thereon, in Escrow Holder’s escrow account
at Bank of America or another New York Clearing House Bank selected by Escrow Holder and approved by Seller (the “Escrow
Account”) and shall cause the Holdback to earn interest at such bank’s then-prevailing insured money market
rates on deposits of similar size. Escrow Holder shall have no liability for any fluctuations in the interest rate paid by such
bank on the Holdback, and is not a guarantor thereof. Any interest shall accrue to the benefit of Seller. Seller shall provide
Escrow Holder with a W-9 form for the Escrow Account.


(b)                               
In the event that Purchaser has not provided written notice of any Claim (as hereinafter defined) containing a description
of the specific nature of such Claim, to Seller (i) asserting a breach of Seller’s representations and warranties set forth
in Section 10.3 of the Purchase Agreement, (ii) relating to Seller’s obligations set forth in Section 7.2 of the Purchase
Agreement, in Paragraph 2 of the Assignment of Partnership Interest, in Paragraph 1 of the Ground Lease Assignment Agreement, or
in Paragraph 3 of the Milford Assignment and Assumption Agreement, or (iii) requesting reimbursement prior to the expiration of
the Entity Representations Survival Period (as defined in the Purchase Agreement) for the actual, out-of-pocket legal fees (such
reimbursable amount not to exceed TWENTY THOUSAND AND 00/100 DOLLARS ($20,000.00)) theretofore incurred by Purchaser in defending
a claim by Recreational Equipment, Inc. relating to the facts alleged in that certain letter dated September 16, 2015 (each, a
“Claim”; and such notice, a “Claim Notice”) after the Closing and prior to
the expiration of the applicable survival period set forth in the Purchase Agreement (the “Survival Period”),
then on August 22, 2016 (the “First Release Date”), Escrow Holder is hereby instructed to release the
Holdback and all accrued interest to Seller. In the event that Purchaser shall have sent a Claim Notice after the Closing and prior
to the end of the applicable Survival Period, then Escrow Holder shall continue to hold the Holdback and all accrued interest;
provided, however, that if Purchaser shall not have commenced a legal proceeding with respect thereto within thirty (30) days after
the expiration of the applicable Survival Period (the “Legal Proceeding Period”; and the day immediately
following the last day of the Legal Proceeding Period applicable to the Entity Representations Survival Period, the “Second
Release Date”), then Seller may at any time on or after the Second Release Date, direct that Escrow Agent release the
Holdback and all accrued interest. If the amount of the Claim claimed in such Claim Notice(s) is less than the Holdback, then Purchaser
and Seller each agree to direct Escrow Holder to release to Seller the portion of the Holdback, including the pro rata portion
of all accrued interest, in excess of the collective amount of such Claims no later than the First Release Date. Upon the final
determination or settlement of all Claims asserted in such Claim Notice(s) prior to the end of the applicable Survival Period that
are the subject of legal proceedings commenced prior to the end of the Legal Proceeding Period, the amount of the Holdback not
required to be disbursed to Purchaser pursuant to such final determination or settlement, in the aggregate, shall be released to
Seller by Escrow Holder, and Purchaser and Seller each agree to direct Escrow Holder to do so.




    2 


     


    

 


(c)                                
If Escrow Holder receives a written request signed by Purchaser stating that Purchaser is entitled to the Holdback, Escrow
Holder shall mail (by reputable overnight courier) a copy of such request to Seller. Seller shall have the right to object in good
faith to such request for the Holdback by written notice of objection delivered to and received by Escrow Holder (with a copy to
Purchaser) not later than ten (10) business days after the date of Escrow Holder’s mailing of such copy to Seller, but not
thereafter. If Escrow Holder shall not have so received a written notice of objection from Seller, Escrow Holder shall deliver
the Holdback to Purchaser. If Escrow Holder shall have received a written notice of objection within the time herein prescribed,
Escrow Holder shall refuse to comply with any requests or demands on it and shall continue to hold the Holdback, together with
any interest earned thereon, until Escrow Holder receives either (A) a written notice signed by both Seller and Purchaser, stating
who is entitled to the Holdback, or (B) a final order of a court of competent jurisdiction directing disbursement of the Holdback
in a specific manner, in either of which events Escrow Holder shall then disburse the Holdback in accordance with such notice or
order. Escrow Holder shall not be or become liable in any way or to any person for its refusal to comply with any such requests
or demands unless and until it has received a direction of the nature described in clauses (A) and (B) immediately
above.


(d)                               
Seller and Purchaser agree, that notwithstanding anything to the contrary in the Purchase Agreement, (i) the Holdback shall
also be available to reimburse as provided in Section 2(b)(iii) hereof, and (ii) Purchaser’s time period to commence
a legal proceeding relating to a Claim shall expire on the thirtieth (30th) day following the expiration of the applicable
Survival Period.


3.              
Any notice to Escrow Holder shall be sufficient only if received by Escrow Holder within the applicable time period set
forth herein. All mailings and notices from Escrow Holder to Seller and/or Purchaser, or from Seller and/or Purchaser to Escrow
Holder, provided for in this Agreement shall be addressed to the party to receive such notice at its notice address set forth in
Section 7 hereof (with copies to be similarly sent to the additional parties therein indicated).


4.              
Notwithstanding the foregoing, if Escrow Holder shall have received a written notice of objection as provided for in Section
2(c) above within the time therein prescribed, or shall have received at any time before actual disbursement of the Holdback,
a written notice signed by either Seller or Purchaser disputing entitlement to the Holdback, or shall otherwise believe in good
faith at any time that a disagreement or dispute has arisen between the parties hereto over entitlement to the Holdback (whether
or not litigation has been instituted), Escrow Holder shall have the right, upon written notice to both Seller and Purchaser, (i)
to deposit the Holdback with the Clerk of the Court in which any litigation is pending and/or (ii) to take such reasonable affirmative
steps as it may, at its option, elect in order to terminate its duties as Escrow Holder, including, without limitation, the depositing
of the Holdback with a court of competent jurisdiction and the commencement of an action for interpleader, the costs thereof to
be borne by whichever of Seller or Purchaser is the losing party, and thereupon Escrow Holder shall be released of and from all
liability hereunder except for any previous gross negligence or willful misconduct. Escrow Holder shall be permitted to use the
Holdback to pay any Escrow Holder Expenses (as defined below), subject to Purchaser’s obligation to reimburse Seller for
its fifty percent (50%) portion as provided in Section 6 below.



    3 


     


    






5.              
Escrow Holder is acting hereunder for a charge of $350.00, to be paid fifty percent (50%) by each of Seller and Purchaser
at the Closing under the Purchase Agreement. It is understood and agreed that Escrow Holder shall not be liable for any error in
judgment or any act done or omitted by it in good faith or pursuant to court order, or for any mistake of fact or law. Escrow Holder
shall not incur any liability in acting upon any document or instrument believed thereby to be genuine. Escrow Holder is hereby
released and exculpated from all liability hereunder, except only for willful misconduct or gross negligence.


6.              
Escrow Holder may assume that any person purporting to give it any notice on behalf of any party has been authorized to
do so. Escrow Holder shall not be liable for, and Seller and Purchaser each hereby severally agrees to indemnify Escrow Holder
against fifty percent (50%) of any loss, liability or expense, including reasonable attorney’s fees (either paid to retained
attorneys or representing the fair value of legal services rendered by Escrow Holder to itself), arising out of any dispute under
this Agreement, including the cost and expense of defending itself against any claim arising hereunder (collectively, “Escrow
Holder Expenses”).


7.              
All notices, certificates and other communications permitted hereunder shall be in writing and may be served and given personally
(with signed delivery receipt obtained) or by reputable overnight courier, addressed as follows and shall be deemed delivered as

8.              
This Agreement shall be binding on and inure to the benefit of all parties hereto and their respective successors and permitted
assigns and may not be modified or amended orally, but only in writing signed by all parties hereto. Neither Seller nor Purchaser
may assign its rights or obligations under this Agreement to any party, except that Purchaser may assign this Agreement to a party
to whom Purchaser assigns its right, title and interest in, to and under the Purchase Agreement to the extent permitted thereunder
and no permitted assignment by Purchaser shall be effective unless and until such party shall have delivered to Escrow Holder (i)
written notice of such assignment and (ii) an assumption agreement with respect to all of the obligations of the assigning party

9.

within the State of New York or to institute a claim of forum non conveniens with respect to any court in the State of New York
for the purposes of litigation with respect to this Agreement.


10.           
Each part of this Agreement is intended to be severable. If any term, covenant, condition or provision of this Agreement
is held to be unlawful, invalid or unenforceable by a court of competent jurisdiction, to the extent permitted by law, such illegality,
invalidity or unenforceability shall not affect the remaining provisions of this Agreement, which shall remain in full force and
effect and shall be binding upon the parties.


11.           
This Agreement may be executed in any number of counterparts, each counterpart for all purposes being deemed an original,
and all such counterparts shall together constitute only one and the same agreement.


12.           
Notwithstanding anything herein to the contrary, interest earned on the Holdback shall be disbursed to the party entitled
to the Holdback or, if both parties are entitled to a portion of the Holdback, the interest earned on the Holdback shall be disbursed
ratably based on the portion of the Holdback received by each such party.


13.           
Nothing herein is intended to modify or amend the provisions of the Purchase Agreement except as provided in Section
2(d) of this Agreement, and in the event of a conflict between the provisions hereof and the provisions of the Purchase Agreement
as to rights or obligations of Purchaser and Seller, the provisions of the Purchase Agreement shall govern except as provided in
Section 2(d) of this Agreement. Seller and Purchaser each agrees that it will not give any notice or require or make any
demands or objections in respect of the Holdback or any part thereof which is contrary to or inconsistent with the provisions of
the Purchase Agreement except as provided in Section 2(d) of this Agreement.
