initial three year term, as provided in Section 14 of the Amendment #1, or if any additional subletting should occur with any company other than C.T.C. during the amended term, than this provision shall be void. 
  
 8. As a form of clarification, in Section 12 of the Lease, any hold-over rent
shall be calculated as 150% of the fixed monthly rent due at the time of the lease expiration or termination. 
  
 9. Landlord, at Tenant’s request, has agreed, to add the following statement at the end of Section 14, “Default and Remedies”:

violation of State or Federal laws. 
  
 10. Landlord, at
Tenant’s request, has agreed to add the following statement to the end of Section 15, “Landlord Obligations”: Landlord shall not be obligated to return Tenant’s security deposit to Tenant, if Landlord sells Premises to a new
owner as long as Landlord fully assigned all rents, security deposits and additional rents to new owner.

 Each Option to Renew granted to Tenant in this Lease is personal to Tenant and may not be exercised or be
assigned by or to any person or entity other than Tenant. The option to Renew does not extend to any subtenant except to C.T.C. 
  
 At the Landlord’s election, the foregoing Option to Renew may not be exercised and will not be effective if, either at the time of the exercise or at
the time of the renewal term is to commence, the Tenant is in default of any of its obligations under the Lease. 
  
 15. Tenant shall be granted a one time Right of First Offer on either all or a portion of the suite currently occupied by the Harleysville Insurance
Company. Should the suite be vacated either partially or in whole by Harleysville, and subordinate to any pre-existing rights of other Tenants in the building, Tenant shall be offered, in writing, the space by Landlord. Tenant shall have 10 days
from the date of notification to indicate its intentions to enter into negotiations on leasing the premises on terms mutually satisfactory to both parties or to indicate no interest in the space. Should no interest be expressed by Tenant after the
aforementioned offer takes place, Landlord shall thereafter be free to pursue any other tenants for the space and shall not be obligated to re-offer the suite to Tenant at any time in the future. This Right of First Offer granted to Tenant in this
Lease is personal to Tenant and may not be exercised or be assigned, by or to any person or entity other than Tenant. The Right of First Offer does not extend to any subtenant except to C.T.C. 
  

 12 

 At Landlord’s election, the foregoing Right of First Offer may not be exercised and will not be
effective if, at the time of the exercise the Tenant is in default of any of its obligations under the Lease. 
  
 16. In the event and only in the event that this Amendment 41 is fully executed and delivered and becomes effective, Landlord agrees to pay Colliers
Pinkard (the “Broker”) a Leasing commission on account of this Amendment #1 in the amount specified in a separate written agreement between Landlord and the Broker. Tenant represents and warrants to Landlord that it has not dealt with any
other realtor, broker or person that might claim a commission or fee in connection with this Amendment #1 other than the Broker and Miller Corporate Real Estate Services and shall indemnify, defend and hold harmless Landlord from and against any
claim, loss, cost, damage or expense (including attorneys’ fees) incurred if such representation or warranty shall not be true and correct. 
  
 17. Landlord and Tenant agree that the Landlord under the Lease is, and at all relevant times has been, “JFB Joint Venture, a Maryland joint
venture”, notwithstanding that the Landlord was incorrectly identified in the Lease as “JFB Joint Venture Limited Partnership, a Maryland limited partnership.” 
  
 18. By its execution of this Amendment #1, Tenant hereby certifies and represents to Landlord that Landlord is in compliance
with all of the terms, covenants and conditions of the Lease and Tenant has no claim or cause of action against or with respect to Landlord or any of its agents, employees or contractors arising out of or in any way connected with the Lease or the
use of the Premises. 
  
 19. Capitalized terms not defined in this
Amendment #1 shall have the meanings ascribed to those terms in the Lease. 
  

 13 

 20. Except as set forth herein, the Lease remains in full force and effect and unmodified. 
  
 21. Time is of the essence of all provisions of this Amendment #1 and remains
of the essence of all provisions of the Lease. 
  
 22. The
provisions of this Amendment #1 shall bind and inure to the benefit of the parties hereto and their respective successors and permitted assigns.

 OPTION TO TERMINATE 
  
 Tenant shall have the opportunity to terminate the Lease, which termination shall be effective on the first day of the thirteenth,
(13th) month after the Commencement Date provided, however, that Tenant delivers written notice to Landlord that it
has elected to so terminate the Lease, which written notice must be delivered at least one hundred twenty (120) days before the date upon which such termination is to become effective and, provided further, that, together with such written notice,
Tenant shall deliver to Landlord a check in the amount of Thirty Thousand Dollars ($30,000.00), representing a non-refundable termination fee. In the event Tenant timely delivers such notice of termination and delivers, with such notice; the sum of
money described above, then the Lease shall terminate effective on the date which is specified in such notice as if such date were the Termination Dame for all purposes of the Lease. Said sum of money shall be non-refundable and Landlord shall be
entitled to retain the full amount, regardless of whether or not Landlord releases all or any part of the Premise. Any purported election to terminate the Lease which does not strictly comply with the terms of this option shall, at Landlord’s
election, be ineffective. 
  
 The option to terminate the lease
granted to Tenant in this Amendment #1 is personal to Tenant and may not be exercised or be assigned by or to any patron or entity other than Tenant. The option to terminate does not extend to any subtenant. 
  
 At Landlord’s election, the foregoing option to terminate may not be
exercised and will not be effective if, either at the time of the exercise or at the time the Lease is to terminate, Tenant is not default of any of its obligations under the Lease.

 The Options to Renew granted to Tenant as to the New Premises are personal to Tenant and may not be
exercised or be assigned by or to any other person or entity other than Tenant. The Options to Renew do not extend to any subtenant. At Landlord’s election, the foregoing Options to Renew may not be exercised and will not be effective if,
either at the time of the exercise or at the time the applicable Renewal Term is to commence, Tenant is in default of any of its obligations under the Lease. 
  
 7. Tenant shall be offered the right of refusal to lease all or any space on the first floor in the building contiguous to the New Premises (herein the
“Expansion Space”), as it may become available from time to time. As used herein, “available” means that the prior lease of such space has expired or otherwise terminated and the prior occupant of such space has vacated and
surrendered possession of such space and Landlord has the right to lease such space to others. This right of refusal shall be subject and subordinate to any currently existing rights to renew, rights of refusal or expansion, or similar options or
rights (collectively, “Superior Rights”) of persons or entities that are tenants of some portion of the Building on the date of this Amendment, and Landlord shall not, under any circumstances, be required to offer to Tenant the right of
refusal to lease any space which is the subject of any Superior Rights. 
  

 8 

 Subject to the terms of the preceding sentence, at anytime after Landlord learns that any Expansion Space
will become available, Landlord shall provide Tenant with written notice of such availability, which notice shall include the date when Tenant would begin occupancy of such Expansion Space. Tenant shall have fifteen (15) days after Landlord’s
written notice to respond to such offer in writing and either unconditionally accept or reject such Expansion Space. Tenant’s failure to respond timely in writing to such offer (or to accept such offer with or subject to any condition) shall be
construed as a rejection of Landlord’s offer. Tenant’s rejection of any Expansion Space in any one instance shall terminate Tenant’s rights to be offered the same Expansion Space or any portion thereof as it may become available again
at some later date, it being agreed that should Tenant reject an offer to lease any particular Expansion Space when offered, Landlord shall have the right to lease all or any part of such Expansion Space to other prospective tenants, without having
to re-offer the Expansion Space to the Tenant. If Tenant unconditionally accepts Landlord’s offer, such acceptance shall be binding upon Landlord and Tenant, provided, however, at the request of either, Landlord and Tenant shall each execute an
amendment of the Lease to reflect the addition of the Expansion Space to the Premises, in accordance with the terms of this Amendment. 
  
 In the event Tenant timely unconditionally accepts, in writing, Landlord’s offer to lease the Expansion Space, then the following shall apply:

  
 (i) Tenant may elect only to lease all of the Expansion Space
offered by Landlord and shall have no right to elect to lease less than all of such Expansion Space. 
  
 (ii) Tenant’s leasing of the Expansion Space shall commence upon the date Landlord makes such Expansion Space available to Tenant. 
  

 9 

 (iii) The Expansion Space shall be delivered in its then “AS IS” condition and Tenant shall be
deemed to have accepted the same in its then “AS IS” condition, and Landlord shall have no obligation to make any repair, refurbishing or improvement to the Expansion Space. 
  
 (iv) If Tenant does elect to lease the Expansion Space, the Expansion Space shall become a part of the New Premises for all
purposes of the Lease and subject to all of the terms and conditions of the Lease as it relates to the New Premises; the term of the Lease, as it relates to the Expansion Space, shall expire on the same day that the term of the Lease, as it relates
to the balance of the New Premises, expires; and the Expansion Space shall be considered a part of the New Premises for purposes of any renewal options available to Tenant; the rentable square footage, for purposes of the Lease (including, but not
limited to, for purposes of calculating the Operating Expense Differential) shall be appropriately increased; and the Base Gross Rent for the Expansion Space shall be the then-current Base Gross Rent being paid by Tenant for the balance of the New
Premises, on a rentable square foot basis (subject to increase whenever the Base Gross Rent for the balance of the New Premises increases). 
  
 This Right of Refusal granted to Tenant is personal to Tenant and may not be exercised or be assigned by or to any person or entity other than Tenant
without the prior written consent of Landlord. The Right of Refusal does not extend to any subtenant and may only be exercised by the same entity that leases the balance of the New Premises. 
  
 At the Landlord’s election, the foregoing Right of Refusal may not be
exercised and will not be effective if, either at the time of the exercise or at the time the Expansion Space is to become a part of the New Premises, the Tenant is in default of any of its obligations under the Lease. 
  

 10 

 8. Tenant shall not assign, in whole or in part, the Lease as to the New Premises or sublease, in whole
or in part, the New Premises without Landlord’s prior written consent, which consent shall not be unreasonably withheld. Any rental or other compensation of any nature received by Tenant with respect to any assignment or subletting of the New
Premises in excess of the rent reserved in this Amendment as to such portion of the New Premises or any other payment made to Tenant in consideration of such assignment or subletting of the New Premises shall be divided equally between Tenant and
Landlord and Tenant shall immediately pay to Landlord one-half of any such excess or payment as additional rent. 
  
 9. So long as Tenant is not in default of any of its obligations contained in the Lease, Landlord shall make available to Tenant a tenant improvement
allowance (the “Allowance”) in the amount of $50, 000 with respect to Tenant’s improvements and modifications to the New Premises, such amount to be paid by Landlord to Tenant within thirty (30) days following receipt of invoices for
Tenant’s improvements to the New Premises and receipt of lien waivers by Landlord for such work. Any and all improvements, alterations, additions or other modifications to the New Premises must be made subject to and in accordance with the
terms of the Lease, including, but not limited to, Landlord’s approval thereof. In no event will Landlord be required to make any payment on account of the Allowance after the date which is six (6) months after this Amendment. 
  
 10. Tenant acknowledges that certain items or aspects of Tenant’s
proposed improvements to the New Premises are such that Landlord may want them to be removed prior to the expiration of the Lease. Accordingly, and notwithstanding any approval given by Landlord of Tenant’s plans for improvements of or
modifications to the New Premises, Landlord shall have the right to require Tenant, prior to the expiration of the Lease, to remove from the 
  

 11 

 New Premises any improvements, alterations, additions or modifications specified by Landlord to Tenant in a written
notice given by Landlord to Tenant at any time hereafter. Tenant shall restore to then building standard condition, the New Premises after the removal of any such items. 
  
 11. In consideration of Landlord’s agreements with respect to the New Premises, Tenant has also agreed with Landlord to
make the following changes to the Lease as it relates to the Existing Premises: 
  
 a. The term of the Lease as to the existing Premises shall be extended for one (1) year so that such term will end on August 31, 2006. Base Gross Rent for such additional one (1) year period (i.e., September 1, 2005,
to August 31, 2006, shall be at the annual rate of $221, 034.17 and shall be payable monthly at the rate of $18, 419.51 per month. 
  
 b. Landlord and Tenant agree that there is one (1) and only one (1) Remaining Option to Renew the Lease as to the Existing Premises. Such option is for a
two (2) year renewal term. Such Option to Renew shall be in accordance with the terms of paragraph 14 of Amendment #1 to Office Lease Agreement, except that the Basic Gross Rent for such renewal term shall be as follows:

                     August 31, 2008

 WHEREAS, SES has requested that it be permitted to assign the Lease to Tenant, which owns all of the stock of SES and Tenant has requested that Landlord make certain modifications to the terms of the Lease; and 
  
 WHEREAS, Landlord is willing to agree to the assignment and to make the

 WITNESSETH, in consideration of the premises and the mutual covenants herein contained, the Lease is hereby assigned and amended as follows: 

 
 1. Capitalized terms used in this Amendment, but not defined in this
Amendment, shall have the meanings given those terms in the Lease. 
  
 2. Effective the date of this Amendment, SES does hereby irrevocably and unconditionally grant and assign to Tenant (a) all of SES’s right, title and interest in and to the 
  

 15 

 Lease and the Premises (defined below), and (b) all the duties, obligations and liabilities of SES under or relating to
the Lease and/or the Premises. Tenant hereby assumes the Lease. From and after the date hereof, Tenant hereby covenants and agrees to perform and be bound by all of SES’s (and the “Tenant’s”, as that term is defined in the Lease)
duties, obligations and agreements under or relating to the Lease and/or the Premises. SES consents to the modifications to the Lease made in this Amendment. 
  
 3. As used in this Amendment, the “Suite 202 Premises” shall mean the 10, 591 square feet, which was the subject of the Lease, prior to the
execution of this Amendment, and is generally described as Suite 202 in the Building. As used in this Amendment, the “Suite 115 Premises” shall mean the 5, 240 square feet, which was the subject of the Lease prior to the execution of this
Amendment, and is generally described as Suite 115 in the Building. As used in this Amendment, the “Suite 200 Premises” shall mean the 9,603 square feet now to be leased by Tenant and known as Suite 200 in the Building, and more fully

 16 

 Tenant’s occupancy of the Suite 200 Premises shall constitute acceptance thereof and shall be deemed
to constitute Tenant’s agreement that the Suite 200 Premises complies with all requirements of Tenant and all obligations of Landlord with respect to the condition, order and repair thereof. The term of the Lease with respect to the Suite 200
Premises shall extend to and terminate on December 31, 2009.

 9. The Operating Base
Expense of the office area of the Building, as to the Suite 200 Premises shall be the actual operating expenses in excess of the year 2004 per square foot of office rentable area therein. Until September 1, 2006, the Operating Base Expense of the
office area of the Building as to the Suite 202 Premises shall continue to be the actual operating expenses for the year 2000 per square foot of office rentable area therein. Effective September 1, 2006, the Operating Base Expense of the office area
of the Building, as to the Suite 202 Premises shall be the actual operating expenses for the year 2006 per square foot of office rentable area therein. The Operating Base Expense of the office area of the Building, as to the Suite 115 Premises shall
not change and shall continue to be the actual operating expenses for the year 2003 per square foot of office rentable area therein. Except as set forth in this Amendment, Tenant shall pay the Operating Expense Differential for the Suite 200
Premises, the Suite 202 Premises and the Suite 115 Premises in accordance with the provisions of paragraph 2 of the Lease. 
  

 20 

 Notwithstanding the foregoing, the Operating Expenses for Suites 200 and 202 shall be grossed up to reflect a fully
occupied and fully tax assessed building in Howard County. 
  
 10.
Effective the date of this Amendment, all options to renew or extend the term of the Lease for all or and part of the Premises, and all rights of refusal or rights of first option or similar rights to lease additional space in the Building are
terminated. Except as expressly set forth in this Amendment, the Tenant shall have no right to renew or extend the term of the Lease and shall have no rights of refusal or right of first option or any similar right with respect to any additional
space in the Building. 
  
 11. Tenant shall have the Option to
Renew the Lease, for two (2) additional terms of two (2) years each. Such options must be exercised by providing written notice of intention to renew to Landlord not less than one hundred eighty (180) days prior to the expiration of the Lease Term
or the expiration of the first renewal term, as the case may be. All the terms and conditions of the Lease shall remain in full force and effect during the renewal term except that, if Tenant exercises one or both such renewal terms, there shall be
no further right of renewal unless otherwise negotiated. Tenant shall have the right to elect to exercise each Option to Renew as to the Suite 115 Premises and/or the Suite 200 Premises and/or the Suite 202 Premises, except that if Tenant fails to
exercise the first Option to Renew with respect to any such portion of the Premises, then the Tenant shall not be permitted to exercise the second Option to Renew with respect to such portion of the Premises. 
  
 In order to be effective, any notice by Tenant of the exercise of an Option
to Renew must advise Landlord of the portion of the Premises to which the renewal applies and of Landlord’s obligation, described below, to make an initial determination of the Market Rate for the renewal term. The Basic Gross Rent for each
portion of the Premises for which the Tenant exercises its 
  

 21 

 Option to Renew shall be the then prevailing Fair Market Value “Market Rate,” as defined below, as of the first
day of each renewal term. 
  
 The following procedure shall be
used to determine the Market Rate, for each renewal term. Not less than one hundred fifty (150) days prior to the commencement of the renewal term, Landlord shall send to Tenant a written notice specifying its determination of the Market Rate.
Within twenty (20) days after the date of such notice from Landlord, Tenant shall send Landlord a written notice of Tenant’s acceptance or challenge of Landlord’s determination of such Market Rate; provided, however, that in the event that
Tenant fails to respond within such twenty (20) day period, Tenant shall be deemed to have accepted Landlord’s determination of the Market Rate. 
  
 In the event that Tenant challenges Landlord’s determination of the Market Rate and Landlord and Tenant are not able to agree on such Market Rate
within fifteen (15) days (hereinafter referred to as the “Negotiation Period”) after Tenant sends Landlord Tenant’s initial rejection of Landlord’s determination of such Market Rate, then Landlord and Tenant shall each, within
ten (10) days after the expiration of the Negotiation Period, select a real estate broker, each of whom shall be a licensed real estate broker with at least five (5) years’ experience in the Howard County, Maryland market who shall determine
the Market Rate in accordance with this Paragraph. The real estate brokers shall be instructed to complete the procedure independently and to submit their written determinations to Landlord and Tenant within thirty (30) days after their appointment.

  
 In the event that the higher determination of the Market Rate
submitted by one of the real estate brokers is equal to or less than one hundred fifteen percent (115%) of the determination of the Market Rate submitted by the other appraiser, the Market Rate shall be the average of such 
  

 22 

 determinations. If the determination of the Market Rate submitted by one of the real estate brokers is greater than one
hundred fifteen percent (115%) of the determination of the Market Rate submitted by the other appraiser, the real estate brokers shall, within five (5) days of notice from either Landlord or Tenant, appoint a third independent real estate broker
with similar qualifications to make a determination of the Market Rate. The third real estate broker shall be instructed to complete the procedure and to submit a written determination of the Market Rate to Landlord and Tenant within thirty (30)
days after such real estate broker’s appointment. 
  
 The
determination which is neither the highest nor the lowest of the three determinations shall be binding upon Landlord and Tenant as the Market Rate unless two determinations are the same, in which event the Market Rate shall be such amount. Landlord
and Tenant shall each bear the costs of their respective real estate brokers. The expenses of the third appraiser shall be borne one-half (1⁄2) by Landlord and one-half (1⁄2) by Tenant. “Market Rate” shall mean what a Landlord under
no compulsion to lease the Premises and a Tenant under no compulsion to lease the Premises would determine as the Base Gross Rent (including initial monthly rent and annual rental increases), given the other provisions of the Lease which remain
applicable to the parties. Notwithstanding anything to the contrary contained in this Paragraph, in no event shall the Base Gross Rent for any year of the first renewal term be less than the Base Gross Rent for the last full year of the initial term
of the Lease (for the portion of the Premises subject to the Option to Renew), nor shall the Base Gross Rent for any year of the second renewal term be less than the Base Gross Rent for the last full year of the first renewal term (for the portion
of the Premises subject to the Option to Renew). In the event the Market Rate has not been determined by the commencement of a renewal term, Tenant shall continue to pay the Base Gross Rent in effect during the last full year of the initial term or
the first renewal term, as the case may be, until the 
  

 23 

 Market Rate is determined and promptly after such determination, the parties shall make an appropriate adjustment to
reconcile any overpayments or under payments of Base Gross Rent made prior to the determination of the Market Rate. 
  
 The Options to Renew granted to Tenant are personal to Tenant and may not be exercised or be assigned by or to any other person or entity other than
Tenant. The Options to Renew do not extend to any subtenant. 
  
 At Landlord’s election, the foregoing Options to Renew may not be exercised and will not be effective if, either at the time of the exercise or at the time the applicable renewal term is to commence, Tenant is in default of any of its
obligations under the Lease. 
  
 12. Subject to the rights of
existing Tenants, Tenant shall be offered the continuous and recurring right of refusal to lease all or any space in the building contiguous to the Premises on the 1st
or 2nd floors (herein the “Expansion
Space”), as it may become available from time to time. As used herein, “available” means that the prior lease of such space has expired or otherwise terminated and the prior occupant of such space has vacated and surrendered
possession of such space and Landlord has provide Tenant with written notice and they have the right to lease such space to others. This right of refusal shall be subject and subordinate to any currently existing rights to renew, rights of refusal
or expansion, or similar options or rights (collectively, “Superior Rights”) of persons or entities that are tenants of some portion of the Building on the date of this Amendment, and Landlord shall not, under any circumstances, be
required to offer to Tenant the right of refusal to lease any space which is the subject of any Superior Rights. 
  
 Subject to the terms of the preceding sentence, at anytime after Landlord learns that any Expansion Space will become available, Landlord shall provide
Tenant with written notice of 
  

 24 

 such availability, which notice shall include the date when Tenant would begin occupancy of such Expansion Space. Tenant
shall have fifteen (15) days after Landlord’s written notice to respond to such offer in writing and either unconditionally accept or reject such Expansion Space. Tenant’s failure to respond timely in writing to such offer (or to accept
such offer with or subject to any condition) shall be construed as a rejection of Landlord’s offer. Tenant’s rejection of any Expansion Space in any one instance shall terminate Tenant’s rights to be offered the same Expansion Space
or any portion thereof as it may become available again at any time within six (6) months thereafter, it being agreed that should Tenant reject an offer to lease any particular Expansion Space when offered, Landlord shall have the right to lease all
or any part of such Expansion Space to other prospective tenants for six (6) months thereafter, without having to re-offer the Expansion Space to the Tenant. If Tenant unconditionally accepts Landlord’s offer, such acceptance shall be binding
upon Landlord and Tenant, provided, however, at the request of either, Landlord and Tenant shall each execute an amendment of the Lease to reflect the addition of the Expansion Space to the Premises, in accordance with the terms of this Amendment.

  
 In the event Tenant timely unconditionally accepts, in
writing, Landlord’s offer to lease the Expansion Space, then the following shall apply: 
  
 (i) Tenant may elect only to lease all of the Expansion Space offered by Landlord and shall have no right to elect to lease less than all of such Expansion Space. 
  
 (ii) Tenant’s leasing of the Expansion Space shall commence upon the
date Landlord makes such Expansion Space available to Tenant. 
  
 (iii) The Expansion Space shall be delivered in its then “AS IS” condition and Tenant shall be deemed to have accepted the same in its then “AS IS” condition, and Landlord shall have no obligation to make any repair,
refurbishing or improvement to the Expansion Space. 
  

 25 

 (iv) If Tenant does elect to lease the Expansion Space, the Expansion Space shall become a part of the
Premises for all purposes of the Lease and subject to all of the terms and conditions of the Lease as it relates to the Premises; the term of the Lease, as it relates to the Expansion Space, shall expire on the same day that the term of the Lease,
as it relates to the balance of the Premises, expires; and the Expansion Space shall be considered a part of the Premises for purposes of any renewal options available to Tenant. 
  
 (v) Immediately after Tenant unconditionally accepts the Expansion Space, Tenant and Landlord shall confer to determine the
Base Gross Rent to be paid for the Expansion Space. Notwithstanding anything to the contrary contained elsewhere in this Paragraph 12, in the event that Tenant and Landlord cannot agree, in writing, within fifteen (15) days after the date that
Tenant unconditionally accepts the Expansion Space upon the Base Gross Rent and operating expense base year applicable to the Expansion Space, then Tenant’s election shall be deemed null and void. In the event of such inability to agree,
Landlord shall be free to rent the Expansion Space to any other party, as if Tenant’s right of first refusal did not exist. 
  
 In the event that the Expansion Space is added to the Premises, then Landlord and Tenant shall execute an amendment to the Lease formally incorporating
the Expansion Space into the Premises. 
  
 This right of refusal
granted to Tenant is personal to Tenant and may not be exercised or be assigned by or to any person or entity other than Tenant without the prior written consent of Landlord. The right of refusal does not extend to any subtenant and may only be
exercised by the same entity that leases the balance of the Premises. 
  

 26 

 At the Landlord’s election, the foregoing right of refusal may not be exercised and will not be
effective if, either at the time of the exercise or at the time the Expansion Space is to become a part of the Premises, the Tenant is in default of any of its obligations under the Lease. 
  
 13. Tenant shall not assign, in whole or in part, the Lease as to the Suite
200 Premises or sublease, in whole or in part, the Suite 200 Premises without Landlord’s prior written consent, which consent shall not be unreasonably withheld. Any rental or other compensation of any nature received by Tenant with respect to
any assignment or subletting of the Suite 200 Premises in excess of the rent reserved in this Amendment as to such portion of the Suite 200 Premises or any other payment made to Tenant in consideration of such assignment or subletting of the Suite
200 Premises shall be divided equally, minus Tenant’s administrative costs, not to exceed $2, 500.00, between Tenant and Landlord and Tenant shall immediately pay to Landlord one-half (minus Tenant’s administrative costs, not to exceed $2,
500.00), of any such excess or payment as additional rent. 
  
 14.
Landlord is currently in possession of a security deposit under the Lease in the amount of $15, 886.50. Upon execution of this Amendment, Tenant shall deliver to Landlord an additional $4, 113.50 so that the security deposit shall equal $20, 000.00.
Said amount shall continue to be held by Landlord as a security deposit, subject to and in accordance with the terms of the Lease relating to the security deposit. 
  
 15. So long as Tenant is not in default of any of its obligations contained in the Lease, Landlord shall make available to
Tenant a tenant improvement allowance (the “Allowance”) in the amount of $76, 824.00 with respect to Tenant’s improvements and modifications to the Suite 200 Premises, such amount to be paid by Landlord to Tenant within thirty (30)
days following receipt of invoices for Tenant’s improvements to the Suite 200 Premises and receipt of lien 
  

 27 

 waivers by Landlord for such work. Any and all improvements, alterations, additions or other modifications to the Suite
200 Premises must be made subject to and in accordance with the terms of the Lease, including, but not limited to, Landlord’s reasonable approval thereof, not to be unreasonably withheld, conditioned, or delayed. In no event will Landlord be
required to make any payment on account of the Allowance after the date which is one year after this receipt of occupancy permit. Tenant may use the Allowance for all customary hard and soft construction costs; telecommunications equipment and
installation; other specialty trade fixtures and equipment, including suite premises security; and moving costs. Tenant shall submit all plans and specifications (a complete set of construction/permit drawings) to the Landlord for Landlord’s
review and approval, which shall not be unreasonably withheld, conditioned, or delayed. Once permits are procured and prior to construction, permits will be provided to landlord for their reasonable approval prior to commencing with the tenant
improvements to the Premises 
  
 16. Tenant acknowledges that
certain items or aspects of Tenant’s proposed SCIF related improvements only to the Suite 200 Premises are such that Landlord may want them to be removed prior to the expiration of the Lease. Notwithstanding the foregoing, Landlord must notify
Tenant in writing at the time of Landlord’s review and approval of the final Tenant’s plans, of Landlord’s requirement of having Tenant remove such improvements, alterations, additions, or modifications at the end of the lease term.
Accordingly, and notwithstanding any approval given by Landlord of Tenant’s plans for improvements of or modifications to the Suite 200 Premises, Landlord shall have the right to require Tenant, at or about the time Landlord approves

 AMENDMENT #5 TO LEASE AGREEMENT 
 AND ASSIGNMENT AND ASSUMPTION OF LEASE 
  
 THIS AMENDMENT #5 TO LEASE AGREEMENT AND ASSIGNMENT AND ASSUMPTION OF LEASE (this “Amendment”) is made this 1st day of December,
2004, by and between JFB JOINT VENTURE, a Maryland general partnership, hereinafter called “Landlord,” and NCI INFORMATION SYSTEMS, INCORPORATED, a Virginia corporation, hereinafter called “Tenant.” 
  
 WHEREAS, Landlord and Scientific Engineering Solutions, Inc., a Maryland
corporation (“SES”) were parties to an Office Lease Agreement dated April 13, 1998, as amended by Amendment #1 to Office Lease Agreement dated May 30, 2000, by Amendment #2 to Office Lease Agreement dated June 11, 2003, and by Amendment #3
to Office Lease Agreement dated July 18, 2003; and 
  
 WHEREAS,
SES assigned its interest in the Office Lease Agreement to Tenant by Amendment #4 to Lease Agreement and Assignment and Assumption of Lease dated August 20, 2004 (“Amendment #4”), by and among Landlord, Tenant and SES and at the same time
Landlord and Tenant made certain amendments to the Office Lease Agreement (the Office Lease Agreement, as amended prior hereto is hereinafter referred to as the “Lease”); and 
  
 WHEREAS, by this Amendment, Landlord and Tenant desire to make certain other modifications to the terms and conditions of
the Lease, all as more fully described herein below. 
  
 WITNESSETH, in consideration of the premises and the mutual covenants herein contained, the Lease is hereby assigned and amended as follows: 
  
 1. Capitalized terms used in this Amendment, but not defined in this Amendment, shall have the meanings given those terms in the Lease. 

 2. Pursuant to Amendment #4, it was anticipated that Tenant would occupy the Suite 200 Premises beginning
on August 1, 2004, and that Tenant would begin paying rent to Landlord for the Suite 200 Premises on November 1, 2004. The parties have agreed, however, that delivery of the Suite 200 Premises occurred on September 1, 2004, and that Tenant shall be
obligated to pay rent for the Suite 200 Premises commencing on December 1, 2004 (i.e., the Suite 200 Rent Commencement Date shall be December 1, 2004). Landlord shall have no liability to Tenant on account of the timing of the delivery of the Suite
200 Premises. 
  
 To reflect the adjustment described above, the
chart, contained in paragraph 6 of Amendment #4 shall be deleted and replaced with the following.

	  	 	  	$17,162.62

  
 Notwithstanding
anything to the contrary contained in the chart immediately above, Tenant shall not be required to pay Base Gross Rent with respect to the Suite 200 Premises only, until the Suite 200 Rent Commencement Date, which is agreed to be December 1, 2004.

  
 3. The original Office Lease Agreement stated that Tenant
thereunder had paid the first month’s rent and the last month’s rent. Various amendments to the Lease executed prior 
  

 2 

 hereto, stated that Landlord held security deposits (after the payment of $4, 113.50 made pursuant to Amendment #4),
ultimately aggregating $20, 000. In fact, however, Tenant never did pay the last month’s rent (as was erroneously stated in the original Office Lease Agreement) and, in fact, Tenant has not paid all of the security deposit (as erroneously
stated in various amendments to the original Office Lease Agreement). The actual aggregate amount of security deposits paid by Tenant (including those paid by SES) and being held by Landlord is $9, 675.83. Accordingly, by this Amendment, the parties
stipulate and agree that (i) Tenant has not paid all or any portion of the last month’s rent due under the Lease, and (ii) the aggregate amount of the security deposit now being held by Landlord is $9, 675.83. In addition, Landlord and Tenant
agree that Landlord shall accept $9, 675.83 as the security deposit and shall not require, at this time, any additional payment thereof. The said amount shall continue to be held by Landlord as a security deposit, subject to and in accordance with
the terms of the Lease relating to the security deposit. 
  
 4. By
its execution of this Amendment, Tenant hereby certifies and represents to Landlord that Landlord is in compliance with all of the terms, covenants and conditions of the Lease and Tenant has no claim or cause of action against or with respect to
Landlord or any of its agents, employees or contractors arising out of or in any way connected with the Lease or the use of the Premises. 
  
 5. Capitalized terms not defined in this Amendment shall have the meanings ascribed to those terms in the Lease. 
  
 6. Except as set forth herein, the Lease remains in full force and effect and
unmodified. In the event of any inconsistency between the terms of this Amendment and the terms of the Lease, the terms of this Amendment shall prevail and be controlling. 
  

 3 

 7. Time is of the essence of all provisions of this Amendment and remains of the essence of all
provisions of the Lease. 
  
 8. The provisions of this Amendment
shall bind and inure to the benefit of the parties hereto and their respective successors and permitted assigns. 
  
 IN WITNESS WHEREOF the parties hereto have executed under seal this Amendment on the day and year first written above.

 THIRD AMENDED AND RESTATED 
 AGREEMENT OF LIMITED PARTNERSHIP 
 OF 
 DIGITAL REALTY TRUST, L.P. 
  
 THIS THIRD AMENDED AND RESTATED AGREEMENT OF LIMITED PARTNERSHIP of Digital Realty Trust, L.P., dated as of July 26, 2005, is entered into by and among
Digital Realty, Inc., a Maryland corporation (the “Company”), as the General Partner and the Persons whose names are set forth on Exhibit A attached hereto, as the Limited Partners, together with any other Persons who become
Partners in the Partnership as provided herein. 
  
 WHEREAS, the
General Partner and the Limited Partners have entered into that certain Second Amended and Restated Agreement of Limited Partnership of Digital Realty Trust, L.P., dated as of February 9, 2005 (the “Second Amended and Restated Partnership
Agreement)”; 
  
 WHEREAS, pursuant to Section 7.3C(2),
the Second Amended and Restated Partnership Agreement may be amended by the General Partner to reflect the issuance of additional Partnership Interests pursuant to Sections 4.3.B, 5.4 and 6.2.B and to set forth the designations, rights, powers,
duties and preferences of the holders of any additional Partnership Interests issued pursuant to Article 4; and 
  
 WHEREAS, the General Partner and the Partnership believe it is desirable and in the best interest of the Partnership to amend and restate the Second
Amended and Restated Partnership Agreement as set forth herein. 
  
 NOW, THEREFORE, pursuant to Sections 2.4 and 7.3C(2) of the Second Amended and Restated Partnership Agreement, the General Partner, on its own behalf and as attorney-in-fact for the Limited Partners, hereby amends and restates the Second
Amended and Restated Partnership Agreement as follows: 
  
 ARTICLE 1. 
 DEFINED TERMS 
  

	Section	1.1 Definitions. 

  
 The following definitions shall be for all purposes, unless otherwise clearly indicated to the contrary, applied to the terms used in this Agreement.

  
 “Act” means the Maryland Revised Uniform
Limited Partnership Act, as it may be amended from time to time, and any successor to such statute. 
  
 “Additional Funds” shall have the meaning set forth in Section 4.3.A. 

 “Additional Limited Partner” means a Person admitted to the Partnership as a Limited
Partner pursuant to Section 12.2 and who is shown as such on the books and records of the Partnership. 
  
 “Adjusted Capital Account Deficit” means, with respect to any Partner, the deficit balance, if any, in such Partner’s Capital
Account as of the end of the relevant fiscal year, after giving effect to the following adjustments: 
  

	 	(i)	decrease such deficit by any amounts which such Partner is obligated to restore pursuant to this Agreement or is deemed to be obligated to restore pursuant to Regulations Section
1.704-1(b)(2)(ii)(c) or the penultimate sentence of each of Regulations Sections 1.704-2(i)(5) and 1.704-2(g); and 

  

	 	(ii)	increase such deficit by the items described in Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) and (6). 

  
 The foregoing definition of Adjusted Capital Account Deficit is intended to comply with the provisions of Regulations
Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith. A positive balance in a Partner’s Capital Account, after giving effect to the adjustments described above in clauses (i) and (ii), is referred to in this Agreement as
an “Adjusted Capital Account Balance.” 
  
 “Adjustment Date” means, with respect to any Capital Contribution, the close of business on the Business Day last preceding the date of the Capital Contribution, provided, that if such Capital Contribution is
being made by the General Partner in respect of the proceeds from the issuance of REIT Shares (or the issuance of the General Partner’s securities exercisable for, convertible into or exchangeable for REIT Shares), then the Adjustment Date
shall be as of the close of business on the Business Day last preceding the date of the issuance of such securities. 
  
 “Adjustment Event” shall have the meaning set forth in Section 4.5.A. 
  
 “Affiliate” means, with respect to any Person, any Person

predecessors to be held by more than seven (7) partners, including as partners any flow through partners.

any Person that is not the General Partner upon such terms as the General Partner determines appropriate; provided that, the Partnership shall not incur any Debt that is recourse to the General Partner, except to the extent otherwise
agreed to by the General Partner in its sole discretion.

 Section 4.3 Additional Funding and Capital Contributions 
  
 A. General. The General Partner may, at any time and from time to
time determine that the Partnership requires additional funds (“Additional Funds”) for the acquisition of additional Properties or for such other Partnership purposes as the General Partner may determine. Additional Funds may be
raised by the Partnership, at the election of the General Partner, in any manner provided in, and in accordance with, the terms of this Section 4.3. No Person shall have any preemptive, preferential or similar right or rights to subscribe for
or acquire any Partnership Interest, except as set forth in this Section 4.3. 
  
 B. Issuance of Additional Partnership Interests. The General Partner, in its sole and absolute discretion, may raise all or any portion of the Additional Funds by accepting additional Capital Contributions of
cash. The General Partner may also accept additional Capital Contributions of real property or any other non-cash assets. In connection with any such additional Capital Contributions (of cash or property), the General Partner is hereby authorized to
cause the Partnership from time to time to issue to Partners (including the General Partner) or other Persons (including, without limitation, in connection with the contribution of tangible or intangible property, services, or other consideration
permitted by the Act to the Partnership) additional Partnership Units or other Partnership Interests, which may be Common Units or other Partnership Units issued in one or more classes, or one or more series of any of such classes, with such
designations, preferences and relative, participating, optional, conversion, exchange or other special rights, powers, and duties, including rights, powers, and duties senior to then existing Limited Partner Interests, all as shall be determined by
the General Partner in its sole and absolute discretion subject to Maryland law, including without limitation, (i) the allocations of items of Partnership income, gain, loss, deduction, and credit to such class or series of Partnership Interests;
(ii) the right of each such class or series of Partnership Interests to share in Partnership distributions; (iii) the rights of each such class or series of Partnership Interests upon dissolution and liquidation of the Partnership; and (iv) the
right to vote, including, without limitation, the Limited Partner approval rights set forth in Section 11.2.A; provided, that no such additional Partnership Units or other Partnership Interests shall be issued to the General
Partner unless either (a) (1) the additional Partnership Interests are issued in connection with the grant, award, or issuance of shares of the General Partner pursuant to Section 4.3.C below, which shares have designations, preferences, and
other rights (except voting rights) such that the economic interests attributable to such shares are substantially similar to the designations, preferences and other rights of the additional Partnership Interests issued to the General Partner in
accordance with this Section 4.3.B, and (2) the General Partner shall make a Capital Contribution to the Partnership in an amount equal to any net proceeds raised in connection with such issuance, or (b) the additional Partnership Interests
are issued to all Partners holding Partnership Interests in the same class in proportion to their respective Percentage Interests in such class or (c) the additional Partnership Interests are issued pursuant to a Stock Plan. The General
Partner’s determination that consideration is adequate shall be conclusive insofar as the adequacy of consideration relates to whether the Partnership Interests are validly issued and paid. In the event that the Partnership issues additional
Partnership Interests pursuant to this Section 4.3.B, the General Partner shall make such revisions to this Agreement (including but not limited to the revisions described in Section 5.4, Section 6.2.B, and Section 8.6)
as it determines are necessary to reflect the issuance of such additional Partnership Interests. 
  

 26 

 C. Issuance of REIT Shares or Other Securities by the General Partner. Except as provided in the
next following paragraph of this Section 4.3C, the General Partner shall not issue any additional REIT Shares, other shares of capital stock of the General Partner or New Securities (other than REIT Shares issued pursuant to Section
8.6 or such shares, stock or securities pursuant to a dividend or distribution (including any stock split) to all of its stockholders or all of its stockholders who hold a particular class of stock of the General Partner), unless (i) the General
Partner shall cause the Partnership to issue to the General Partner, Partnership Interests or rights, options, warrants or convertible or exchangeable securities of the Partnership having designations, preferences and other rights, all such that the
economic interests thereof are substantially similar to those of the REIT Shares, other shares of capital stock of the General Partner or New Securities issued by the General Partner and (ii) the General Partner shall make a Capital Contribution of
any net proceeds from the issuance of such additional REIT Shares, other shares of capital stock or New Securities, as the case may be, and from any exercise of the rights contained in such additional New Securities, as the case may be. Without
limiting the foregoing, the General Partner is expressly authorized to issue REIT Shares, other shares of capital stock of the General Partner or New Securities for no tangible value or for less than fair market value, and the General Partner is
expressly authorized to cause the Partnership to issue to the General Partner corresponding Partnership Interests, so long as (x) the General Partner concludes in good faith that such issuance of Partnership Interests is in the interests of the
Partnership; and (y) the General Partner contributes all proceeds, if any, from such issuance and exercise to the Partnership. 
  
 In connection with the General Partner’s initial public offering of REIT Shares, any other issuance of REIT Shares, other capital stock of the
General Partner or New Securities, the General Partner shall contribute to the Partnership, any net proceeds raised in connection with such issuance; provided, that the General Partner may use a portion of the net proceeds from any
offering to acquire Partnership Units or other assets (provided such other assets are contributed to the Partnership pursuant to the terms of this Agreement); and provided, further, that if the net proceeds actually
received by the General Partner are less than the gross proceeds of such issuance as a result of any underwriter’s discount or other expenses paid or incurred in connection with such issuance then, except to the extent such net proceeds are
used to acquire Partnership Units, the General Partner shall be deemed to have made a Capital Contribution to the Partnership in the amount equal to the sum of the net proceeds of such issuance plus the amount of such underwriter’s discount and
other expenses paid by the General Partner (which discount and expense shall be treated as an expense for the benefit of the Partnership for purposes of Section 7.4). In the case of issuance of REIT Shares by the General Partner in any
offering, whether registered under the Securities Act or exempt from such registration, underwritten, offered and sold directly to investors or through agents or other intermediaries, or otherwise distributed, for purposes of determining the number
of additional Common Units issuable upon a Capital Contribution funded by the net proceeds thereof consistently with the immediately preceding sentence, any discount from the then current market price of REIT Shares shall be disregarded such that an
equal number of Common Units can be issued to the General Partner as the number of REIT Shares sold by the General Partner in such offering, consistently with the determination of Partners’ Percentage Interests as provided in Section
4.3.D. In the case of issuances of REIT Shares, other capital stock of the General Partner or New Securities pursuant to any Stock Plan at a discount from fair market value or for no value, the amount of such discount representing compensation
to the employee, as determined by the General Partner, 

  

 27 

 
shall be treated as an expense for the benefit of the Partnership for purposes of Section 7.4 and, as a result, the General Partner shall be deemed to
have made a Capital Contribution to the Partnership in an amount equal to the sum of any net proceeds of such issuance plus the amount of such expense. 
  
 D. Percentage Interest Adjustments in the Case of Capital Contributions for Partnership Units. Upon the acceptance of additional Capital
Contributions in exchange for any class or series of Partnership Units, the Percentage Interest of each Partner in such class or series of Partnership Units shall be equal to a fraction, the numerator of which is equal to the sum of (i) the Deemed
Partnership Interest Value of the Partnership Interest of such Partner in respect of such class or series (computed as of the Business Day immediately preceding the Adjustment Date) and (ii) the Agreed Value of additional Capital Contributions, if
any, made by such Partner to the Partnership in such class or series of Partnership Interests as of such Adjustment Date, and the denominator of which is equal to the sum of (i) the Deemed Value of the Partnership Interests of such class or series
(computed as of the Business Day immediately preceding the Adjustment Date), plus (ii) the aggregate Agreed Value of additional Capital Contributions contributed by all Partners and/or third parties to the Partnership on such Adjustment Date
in such class or series. Provided, however, solely for purposes of calculating a Partner’s Percentage Interest pursuant to this Section 4.3.D, (i) in the case of cash Capital Contributions by the General Partner funded by
an offering of REIT Shares or other shares of capital stock of the General Partner and (ii) in the case of the contribution of properties by the General Partner which were acquired by the General Partner in exchange for REIT Shares or other shares
of capital stock of the General Partner immediately prior to such contribution, the General Partner shall be issued a number of Partnership Units equal and corresponding to the number of such shares issued by the General Partner in exchange for such
cash or Properties, the Partnership Units held by the other Partners shall not be adjusted, and the Partners’ Percentage Interests shall be adjusted accordingly. The General Partner shall promptly give each Partner written notice of its
Percentage Interest, as adjusted. This Section 4.3.D shall not apply to the issuance of Profits Interest Units, which shall be governed by Section 4.5, and the General Partner may adjust Percentage Interests in a manner that is
different from the provisions of this Section 4.3.D to the extent it reasonably determines it is appropriate to do so to reflect the value of the respective Capital Contributions made to the Partnership and the number of Partnership Units
issued with respect thereto. 
  

 28 

 Section 4.4 Other Contribution Provisions. In the event that any Partner is admitted to the Partnership and is
given (or is treated as having received) a Capital Account at the time of admission in exchange for services rendered to the Partnership, such transaction shall be treated by the Partnership and the affected Partner as if the Partnership had
compensated such Partner in cash, and the Partner had contributed such cash to the capital of the Partnership. In addition, with the consent of the General Partner, in its sole discretion, one or more Limited Partners may enter into agreements with
the Partnership, in the form of a guarantee or contribution agreement, which have the effect of providing a guarantee of certain obligations of the Partnership. 
  

Section 4.5 Profit Interest Units. The General Partner may from time to time issue Profits Interest Units to Persons who provide services to the Partnership,
for such consideration or for no consideration as the General Partner may determine to be appropriate, and admit such Persons as Limited Partners. Subject to the following provisions of this Section 4.5 and the special provisions of Sections 4.3.D,
6.2.C, 8.7 and 8.8, Profits Interest Units shall be treated as Common Units, with all of the rights, privileges and obligations attendant thereto. For purposes of computing the Partners’ Percentage Interests, Profits Interest Units shall be
treated as Common Units. In particular, the Partnership shall maintain at all times a one-to-one correspondence between Profits Interest Units and Common Units for conversion, distribution and other purposes, including without limitation complying
with the following procedures: 
  
 A. If an Adjustment Event
occurs, then the General Partner shall make a corresponding adjustment to the Profits Interest Units to maintain a one-for-one conversion and economic equivalence ratio between Common Units and Profits Interest Units. The following shall be
“Adjustment Events”: (i) the Partnership makes a distribution on all outstanding Common Units in Partnership Units, (ii) the Partnership subdivides the outstanding Common Units into a greater number of units or combines the
outstanding Common Units into a smaller number of units, or (iii) the Partnership issues any Partnership Units in exchange for its outstanding Common Units by way of a reclassification or recapitalization of its Common Units. If more than one
Adjustment Event occurs, the adjustment to the Profits Interest Units need be made only once using a single formula that takes into account each and every Adjustment Event as if all Adjustment Events occurred simultaneously. For the avoidance of
doubt, the following shall not be Adjustment Events: (x) the issuance of Partnership Units in a financing, reorganization, acquisition or other similar business transaction, (y) the issuance of Partnership Units pursuant to any employee benefit or
compensation plan or distribution reinvestment plan, or (z) the issuance of any Partnership Units to the Company in respect of a Capital Contribution to the Partnership of proceeds from the sale of securities by the Company. If the Partnership takes
an action affecting the Common Units other than actions specifically described above as “Adjustment Events” and in the opinion of the General Partner such action would require an adjustment to the Profits Interest Units to maintain the
one-to-one correspondence described above, the General Partner shall have the right to make such adjustment to the Profits Interest Units, to the extent permitted by law and by any applicable Stock Plan or other compensatory arrangement or incentive
program pursuant to which Profits Interest Units are issued, in such manner and at such time as the General Partner, in its sole discretion, may determine to be reasonably appropriate under the circumstances. If an adjustment is made to the Profits
Interest Units as herein provided the Partnership shall promptly file in the books and records of the Partnership an officer’s certificate setting forth such adjustment and a brief statement of the facts requiring such adjustment, which
certificate shall be conclusive evidence of the correctness of 

  

 29 

 
such adjustment absent manifest error. Promptly after filing of such certificate, the Partnership shall mail a notice to each Profits Interest Unitholder
setting forth the adjustment to his or her Profits Interest Units and the effective date of such adjustment. 
  
 B. Unless otherwise provided by the General Partner with respect to any particular class or series of Profits Interest Units, the Profits Interest
Unitholders shall, in respect of each Distribution Payment Date, when, as and if authorized and declared by the General Partner out of assets legally available for that purpose, be entitled to receive distributions in an amount per Profits Interest
Unit equal to the distributions per Common Unit, paid to holders of record on the same record date established by the General Partner with respect to such Distribution Payment Date. References to additional Partnership Interests in Section
5.4 shall be deemed to include Profits Interest Units issued during a Distribution Period and such Section 5.4 shall apply in full to Profits Interest Units. Unless otherwise provided by the General Partner with respect to any particular
class or series of Profits Interest Units, (x) during any Distribution Period, so long as any Profits Interest Units are outstanding, no distributions (whether in cash or in kind) shall be authorized, declared or paid on Common Units, unless equal
distributions have been or contemporaneously are authorized, declared and paid on the Profits Interest Units for such Distribution Period, (y), the Profits Interest Units shall rank pari passu with the Common Units as to the payment of
regular and special periodic or other distributions and distribution of assets, and (z) any class or series of Partnership Units or Partnership Interests which by its terms specifies that it shall rank junior to, on a parity with, or senior to the
Common Units with respect to distributions shall also rank junior to, on a parity with, or senior to, as the case may be, the Profits Interest Units. Notwithstanding the foregoing provisions of this Section 4.5.B, proceeds from a Liquidating
Event shall be distributed to Holders of Partnership Units as set forth in Sections 5.3 and 13.2. Subject to the terms of any Vesting Agreement, a Profits Interest Unitholder shall be entitled to transfer his or her Profits Interest
Units to the same extent, and subject to the same restrictions as holders of Common Units are entitled to transfer their Common Units pursuant to Article 11. 
  
 C. Profits Interest Units shall be subject to the following special provisions: 
  
 (a) Vesting Agreements. Profits Interest Units may, in the sole
discretion of the General Partner, be issued subject to vesting, forfeiture and additional restrictions on transfer pursuant to the terms of a Vesting Agreement. The terms of any Vesting Agreement may be modified by the General Partner from time to
time in its sole discretion, subject to any restrictions on amendment imposed by the relevant Vesting Agreement or by the Plan, if applicable. Profits Interest Units that were fully vested when issued or that have vested under the terms of a Vesting
Agreement are referred to as “Vested Profits Interest Units”; all other Profits Interest Units shall be treated as “Unvested Profits Interest Units.” 
  
 (b) Forfeiture. Unless otherwise specified in the Vesting Agreement or in any applicable Stock Plan or other
compensatory arrangement or incentive program pursuant to which Profits Interest Units are issued, upon the occurrence of any event specified in such Vesting Agreement, Stock Plan, arrangement or program as resulting in either the right of the
Partnership or the General Partner to repurchase Profits Interest Units at a specified purchase price or some other forfeiture of any Profits Interest Units, then if the Partnership or 

  

 30 

 
the General Partner exercises such right to repurchase or forfeiture or upon the occurrence of the event causing forfeiture in accordance with the applicable
Vesting Agreement, Stock Plan, arrangement or program, then the relevant Profits Interest Units shall immediately, and without any further action, be treated as cancelled and no longer outstanding for any purpose. Unless otherwise specified in the
applicable Vesting Agreement, Stock Plan, arrangement or program, no consideration or other payment shall be due with respect to any Profits Interest Units that have been forfeited, other than any distributions declared with respect to a Partnership
Record Date prior to the effective date of the forfeiture. In connection with any repurchase or forfeiture of Profits Interest Units, the balance of the portion of the Capital Account of the Profits Interest Unitholder that is attributable to all of
his or her Profits Interest Units shall be reduced by the amount, if any, by which it exceeds the target balance contemplated by Section 6.2.C, calculated with respect to the Profits Interest Unitholder’s remaining Profits Interest
Units, if any.  
  
 (c) Allocations. Profits
Interest Unitholders shall be entitled to certain special allocations of gain under Section 6.2.C. 
  
 (d) Redemption. The Redemption Right provided to Limited Partners under Section 8.6 shall not apply with respect to Profits Interest Units
unless and until they are converted to Partnership Units as provided in clause (vi) below and Section 8.7. 
  
 (e) Legend. Any certificate evidencing an Profits Interest Unit shall bear an appropriate legend indicating that additional terms, conditions and
restrictions on transfer, including without limitation any Vesting Agreement, apply to the Profits Interest Unit. 
  
 (f) Conversion to Partnership Units. Vested Profits Interest Units are eligible to be converted into Partnership Units under Section 8.7.

  
 (g) Voting. Profits Interest Units shall have the
voting rights provided in Section 8.8. 
  
 Section 4.6 No Preemptive
Rights 
  
 Except to the extent expressly granted by the
Partnership pursuant to another agreement, no Person shall have any preemptive, preferential or other similar right with respect to (i) additional Capital Contributions or loans to the Partnership or (ii) issuance or sale of any Partnership Units or
other Partnership Interests. 
  
 ARTICLE 5. 
 DISTRIBUTIONS 
  
 Section 5.1 Requirement and Characterization of Distributions 
  
 The General Partner shall cause the Partnership to distribute quarterly all, or such portion as the General Partner may in its discretion determine, of
Available Cash generated by the Partnership to the Partners who are Partners on the applicable Partnership Record Date with respect to such distribution, (1) first, with respect to any class or series of Partnership Interests that are entitled to
any preference in distributions, in accordance with the rights of such class or 

  

 31 

 
series of Partnership Interests (and within such class or series, pro rata in proportion to the respective Percentage Interests on the applicable Partnership
Record Date), and (2) second, with respect to any class or series of Partnership Interests that are not entitled to any preference in distributions, pro rata to each such class or series in accordance with the terms of such class or series to the
Partners who are Partners of such class or series on the Partnership Record Date with respect to such distribution (and within each such class or series, pro rata in proportion to the respective Percentage Interests on such Partnership Record Date).
Unless otherwise expressly provided for herein or in an agreement, if any, entered into in connection with the creation of a new class or series of Partnership Interests created in accordance with Article 4, no Partnership Interest shall be
entitled to a distribution in preference to any other Partnership Interest. The General Partner shall take such reasonable efforts, as determined by it in its sole and absolute discretion and consistent with its qualification as a REIT, to cause the
Partnership to distribute sufficient amounts to enable the General Partner, for so long as the General Partner has determined to qualify as a REIT, to pay stockholder dividends that will (a) satisfy the requirements for qualifying as a REIT under
the Code and Regulations (“REIT Requirements”), and (b) except to the extent otherwise determined by the General Partner, avoid the imposition of any federal income or excise tax liability on the General Partner, except to the
extent that a distribution pursuant to clause (b) would prevent the Partnership from making a distribution to the Holders of Series A Preferred Units in accordance with Section 16.2 or Series B Preferred Units in accordance with Section
17.2. 
  
 Section 5.2 Distributions in Kind 
  
 Except as expressly provided herein, no right is given to any Partner to
demand and receive property other than cash. The General Partner may determine, in its sole and absolute discretion, to make a distribution in-kind to the Partners of Partnership assets, and such assets shall be distributed in such a fashion as to
ensure that the fair market value is distributed and allocated in accordance with Articles 5, 6 and 10. 
  
 Section 5.3 Distributions Upon Liquidation 
  
 Notwithstanding Section 5.1, proceeds from a Liquidating Event shall be distributed to the Partners in accordance with Section 13.2.

  
 Section 5.4 Distributions to Reflect Issuance of Additional Partnership
Interests 
  
 In the event that the Partnership issues
additional Partnership Interests to the General Partner or any Additional Limited Partner pursuant to Section 4.3.B, 4.3.C or 4.5, the General Partner shall make such revisions to this Article 5 as it determines are
necessary to reflect the issuance of such additional Partnership Interests. In the absence of any agreement to the contrary, an Additional Limited Partner shall be entitled to the distributions set forth in Section 5.1 (without regard to this
Section 5.4) with respect to the period during which the closing of its contribution to the Partnership occurs, multiplied by a fraction the numerator of which is the number of days from and after the date of such closing through the end of
the applicable period, and the denominator of which is the total number of days in such period. 
  

 32 

 ARTICLE 6. 
 ALLOCATIONS 
  
 Section 6.1 Timing and Amount
of Allocations of Net Income and Net Loss 
  
 Net Income and
Net Loss of the Partnership shall be determined and allocated with respect to each Partnership Year of the Partnership as of the end of each such year. Subject to the other provisions of this Article 6, an allocation to a Partner of a share
of Net Income or Net Loss shall be treated as an allocation of the same share of each item of income, gain, loss or deduction that is taken into account in computing Net Income or Net Loss. 
  
 Section 6.2 General Allocations 
  
 Except as otherwise provided in this Article 6, Net Income and Net
Loss allocable with respect to a class of Partnership Interests shall be allocated to each of the Holders holding such class of Partnership Interests in accordance with their respective Percentage Interest of such class. 
  
 A. Allocation of Net Income and Net Losses. 
  
 (1) Net Income. Except as otherwise provided in Section 6.3,
Net Income for any Partnership Year shall be allocated to the Partners in the following manner and order of priority: 
  
 (a) First, to the General Partner in an amount equal to the remainder, if any, of the cumulative Net Losses allocated to the General Partner
pursuant to Section 6.2.A.2(d) for all prior Partnership Years minus the cumulative Net Income allocated to the General Partner pursuant to this Section 6.2.A.(1)(a) for all prior Partnership Years; 
  
 (b) Second, to each Limited Partner in an amount equal to the
remainder, if any, of the cumulative Net Losses allocated to each such Limited Partner pursuant to Section 6.2.A.2(c) for all prior Partnership Years minus the cumulative Net Income allocated to such Limited Partner pursuant to this
Section 6.2.A.(1)(b) for all prior Partnership Years; 
  
 (c) Third, to the General Partner in an amount equal to the remainder, if any, of the cumulative Net Losses allocated to the General Partner pursuant to Section 6.2.A.2(b) for all prior Partnership Years minus the
cumulative Net Income allocated to such Partner pursuant to this Section 6.2.A.1(c) for all prior Partnership Years; 
  
 (d) Fourth, to the General Partner in an amount equal to the sum of (i) the excess of the cumulative Series A Priority Return on the Series A
Preferred Units to the last day of the current Partnership Year or to the date of redemption of the Series A Preferred Units, to the extent such Series A Preferred Units are redeemed during such year, over the cumulative Net Income allocated to the
General Partner pursuant to this clause (i) of this Section 6.2.A.1(d) for all prior Partnership Years and (ii) the excess of the cumulative Series B Priority Return on the Series B Preferred Units to the last day of the current
Partnership Year or to the date of redemption of the Series B Preferred Units, to the extent such Series B 

  

 33 

 
Preferred Units are redeemed during such year, over the cumulative Net Income allocated to the General Partner pursuant to this clause (ii) of this
Section 6.2.A.1(d) for all prior Partnership Years; 
  
 (e) Fifth, to the General Partner and the Limited Partners in an amount equal to the remainder, if any, of the cumulative Net Losses allocated to each such Partner pursuant to Section 6.2.A.2(a) for all prior
Partnership Years minus the cumulative Net Income allocated to each Partner pursuant to this Section 6.2.A.(1)(e) for all prior Partnership Years; and 
  
 (f) Sixth, to each of the Partners in accordance with their respective Percentage Interests in the
Common-Equivalent Units. 
  
 To the extent the allocations of Net
Income set forth above in any paragraph of this Section 6.2.A.(1) are not sufficient to entirely satisfy the allocation set forth in such paragraph, such allocation shall be made in proportion to the total amount that would have been
allocated pursuant to such paragraph without regard to such shortfall. 
  
 (2) Net Losses. Except as otherwise provided in Section 6.3, Net Losses for any Partnership Year shall be allocated to the Partners in the following manner and order of priority: 
  
 (a) First, to the General Partner and the Limited Partners in
accordance with their respective Percentage Interests in the Common-Equivalent Units (to the extent consistent with this Section 6.2.A(2)(a)) until the Adjusted Capital Account Balance (ignoring for this purpose any amounts a Partner is
obligated to contribute to the capital of the Partnership or is deemed obligated to contribute pursuant to Regulations Section 1.704-1(b)(2)(ii)(c)(2) and ignoring the General Partner’s Series A Preferred Capital and Series B Preferred Capital)
of each such Partner is zero; 
  
 (b) Second, to the
General Partner (ignoring for this purpose any amounts the General Partner is obligated to contribute to the capital of the Partnership or is deemed obligated to contribute pursuant to Regulations Section 1.704-1(b)(2)(ii)(c)(2)), until the Adjusted
Capital Account (as so modified) of the General Partner is zero; 
  
 (c) Third, to the Limited Partners to the extent of, and in proportion to, the positive balance (if any) in their Adjusted Capital Accounts; and 
  

(d) Fourth, to the General Partner. 
  
 B. Allocations to Reflect Issuance of Additional Partnership Interests. In the event that the Partnership issues additional Partnership
Interests to the General Partner, a Limited Partner or any Additional Limited Partner pursuant to Section 4.3, the General Partner shall make such revisions to this Section 6.2 as it determines are necessary to reflect the terms of the
issuance of such additional Partnership Interests, including making preferential allocations to certain classes of Partnership Interests, subject to the terms of the Series A Preferred Units and the Series B Preferred Units, in accordance with any
method selected by the General Partner. 
  

 34 

 C. Special Allocation of Gain to Profits Interest Unitholders. Notwithstanding the
allocations set forth in Section 6.2.A(1) above, any net capital gains realized in connection with the actual or hypothetical sale of all or substantially all of the assets of the Partnership, including but not limited to net capital gain
treated as realized in connection with an adjustment to the Gross Asset Value of Partnership assets as set forth in the definition of such term, shall first be allocated to the Profits Interest Unitholders until the Economic Capital Account Balances
of such Limited Partners, to the extent attributable to their ownership of Profits Interest Units, are equal to (i) the Common Unit Economic Balance, multiplied by (ii) the number of their Profits Interest Units. For this purpose, the
“Economic Capital Account Balances” of the Profits Interest Unitholders will be equal to their Capital Account balances, plus the amount of their shares of any Partner Minimum Gain or Partnership Minimum Gain, in each case to the
extent attributable to their ownership of Profits Interest Units. Similarly, the “Common Unit Economic Balance” shall mean (i) the Capital Account balance of the Company, plus the amount of the Company’s share of any Partner
Minimum Gain or Partnership Minimum Gain, in either case to the extent attributable to the Company’s ownership of Common Units and computed on a hypothetical basis after taking into account all allocations through the date on which any
allocation is made under this Section 6.2.C, divided by (ii) the number of the Company’s Common Units. Any such allocations shall be made among the Profits Interest Unitholders in proportion to the amounts required to be allocated to
each under this Section 6.2.C. The parties agree that the intent of this Section 6.2.C is to make the Capital Account balances of the Profits Interest Unitholders with respect to their Profits Interest Units economically equivalent to
the Capital Account balance of the Company with respect to its Common Units. 
  
 D. Allocations in Connection with a Liquidating Event. Except as otherwise provided in Section 6.3, the allocations of Net Income and Net Loss set forth in the foregoing provisions of this Section 6.2
or, if necessary, allocations of individual items of income, gain, loss and deduction which comprise such Net Income or Net Loss, shall be adjusted to the extent necessary so as to result in the Capital Account balance of each Partner being such
that distributions to the Partners pursuant to Section 13.2 hereof upon the occurrence of a Liquidating Event shall be made first to the General Partner in an amount equal to the sum of the Series A Preferred Capital and the Series B Preferred
Capital, and thereafter to Holders of Common-Equivalent Units in accordance with their Percentage Interests in such Units.  
  
 Section 6.3 Additional Allocation Provisions 
  
 Notwithstanding the foregoing provisions of this Article 6: 
  
 A. Regulatory Allocations. 
  

(i) Minimum Gain Chargeback. Except as otherwise provided in Regulations Section 1.704-2(f), notwithstanding the provisions of Section
6.2, or any other provision of this Article 6, if there is a net decrease in Partnership Minimum Gain during any Partnership Year, each Holder shall be specially allocated items of Partnership income and gain for such year (and, if
necessary, subsequent years) in an amount equal to such Holder’s share of the net decrease in Partnership Minimum Gain, as determined under Regulations Section 1.704-2(g). Allocations pursuant to the previous sentence shall be made in
proportion to the respective amounts required to be allocated to each Holder pursuant thereto. The items to be allocated shall 

  

 35 

 
be determined in accordance with Regulations Sections 1.704-2(f)(6) and 1.704-2(j)(2). This Section 6.3.A(i) is intended to qualify as a “minimum
gain chargeback” within the meaning of Regulation Section 1.704-2(f) which shall be controlling in the event of a conflict between such Regulation and this Section 6.3.A(i). 
  
 (ii) Partner Minimum Gain Chargeback. Except as otherwise provided in Regulations Section 1.704-2(i)(4), and
notwithstanding the provisions of Section 6.2, or any other provision of this Article 6 (except Section 6.3.A(i)), if there is a net decrease in Partner Minimum Gain attributable to a Partner Nonrecourse Debt during any
Partnership Year, each Holder who has a share of the Partner Minimum Gain attributable to such Partner Nonrecourse Debt, determined in accordance with Regulations Section 1.704-2(i)(5), shall be specially allocated items of Partnership income and
gain for such year (and, if necessary, subsequent years) in an amount equal to such Holder’s share of the net decrease in Partner Minimum Gain attributable to such Partner Nonrecourse Debt, determined in accordance with Regulations Section
1.704-2(i)(4). Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to each Holder pursuant thereto. The items to be so allocated shall be determined in accordance with
Regulations Sections 1.704-2(i)(4) and 1.704-2(j)(2). This Section 6.3.A(ii) is intended to qualify as a “chargeback of partner nonrecourse debt minimum gain” within the meaning of Regulation Section 1.704-2(i) which shall be
controlling in the event of a conflict between such Regulation and this Section 6.3.A(ii). 
  
 (iii) Nonrecourse Deductions and Partner Nonrecourse Deductions. Any Nonrecourse Deductions for any Partnership Year shall be specially allocated
to the Holders in accordance with their respective Percentage Interests in Common-Equivalent Units. Any Partner Nonrecourse Deductions for any Partnership Year shall be specially allocated to the Holder(s) who bears the economic risk of loss with
respect to the Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable, in accordance with Regulations Sections 1.704-2(b)(4) and 1.704-2(i). 
  
 (iv) Qualified Income Offset. If any Holder unexpectedly receives an adjustment, allocation or distribution
described in Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of Partnership income and gain shall be allocated, in accordance with Regulations Section 1.704-1(b)(2)(ii)(d), to the Holder in an amount and manner sufficient to
eliminate, to the extent required by such Regulations, the Adjusted Capital Account Deficit of the Holder as quickly as possible provided that an allocation pursuant to this Section 6.3.A(iv) shall be made if and only to the extent that such
Holder would have an Adjusted Capital Account Deficit after all other allocations provided in this Article 6 have been tentatively made as if this Section 6.3.A(iv) were not in this Agreement. It is intended that this Section
6.3.A(iv) qualify and be construed as a “qualified income offset” within the meaning of Regulations 1.704-1(b)(2)(ii)(d), which shall be controlling in the event of a conflict between such Regulations and this Section 6.3.A(iv).

  
 (v) Gross Income Allocation. In the event any Holder
has a deficit Capital Account at the end of any Partnership Year which is in excess of the sum of (1) the amount (if any) such Holder is obligated to restore to the Partnership, and (2) the amount such Holder is deemed to be obligated to restore
pursuant to Regulations Section 1.704-1(b)(2)(ii)(c) 

  

 36 

 
or the penultimate sentences of Regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5), each such Holder shall be specially allocated items of Partnership
income and gain in the amount of such excess as quickly as possible, provided, that an allocation pursuant to this Section 6.3.A(v) shall be made if and only to the extent that such Holder would have a deficit Capital Account in
excess of such sum after all other allocations provided in this Article 6 have been tentatively made as if this Section 6.3.A(v) and Section 6.3.A(iv) were not in this Agreement. 
  
 (vi) Limitation on Allocation of Net Loss. To the extent any
allocation of Net Loss would cause or increase an Adjusted Capital Account Deficit as to any Holder, such allocation of Net Loss shall be reallocated among the other Holders in accordance with their respective Percentage Interests in
Common-Equivalent Units subject to the limitations of this Section 6.3.A(vi). 
  
 (vii) Section 754 Adjustment. To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Code Section 734(b) or Code Section 743(b) is required, pursuant to Regulations Section
1.704-1(b)(2)(iv)(m)(2) or Regulations Section 1.704-1(b)(2)(iv)(m)(4), to be taken into account in determining Capital Accounts as the result of a distribution to a Holder in complete liquidation of his interest in the Partnership, the amount of
such adjustment to the Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis) and such gain or loss shall be specially allocated to the Holders in
accordance with their interests in the Partnership in the event that Regulations Section 1.704-1(b)(2)(iv)(m)(2) applies, or to the Holders to whom such distribution was made in the event that Regulations Section 1.704-1(b)(2)(iv)(m)(4) applies.

  
 (viii) Curative Allocation. The allocations set forth
in Sections 6.3.A(i), (ii), (iii), (iv), (v), (vi), and (vii) (the “Regulatory Allocations”) are intended to comply with certain regulatory requirements, including the requirements of
Regulations Sections 1.704-1(b) and 1.704-2. Notwithstanding the provisions of Sections 6.1 and 6.2 (but subject to Section 6.2.D), the Regulatory Allocations shall be taken into account in allocating other items of income, gain, loss
and deduction among the Holders so that, to the extent possible, the net amount of such allocations of other items and the Regulatory Allocations to each Holder shall be equal to the net amount that would have been allocated to each such Holder if
the Regulatory Allocations had not occurred. 
  
 B. For purposes
of determining a Holder’s proportional share of the “excess nonrecourse liabilities” of the Partnership within the meaning of Regulations Section 1.752-3(a)(3), each Holder’s interest in Partnership profits shall be such
Holder’s Percentage Interest in Common-Equivalent Units. 
  
 Section 6.4
Tax Allocations 
  
 A. In General. Except as
otherwise provided in this Section 6.4, for income tax purposes each item of income, gain, loss and deduction (collectively, “Tax Items”) shall be allocated among the Holders in the same manner as its correlative item of
“book” income, gain, loss or deduction is allocated pursuant to Sections 6.2 and 6.3. 
  

 37 

 B. Allocations Respecting Section 704(c) Revaluations. Notwithstanding Section 6.4.A, Tax
Items with respect to Partnership property that is contributed to the Partnership by a Partner shall be shared among the Holders for income tax purposes pursuant to Regulations promulgated under Section 704(c) of the Code, so as to take into account
the variation, if any, between the basis of the property to the Partnership and its initial Gross Asset Value. With respect to Partnership property that is contributed to the Partnership in connection with the General Partner’s initial public
offering or pursuant to the Partnership’s exercise of rights under any Option Agreement or ROFO Agreement, such variation between basis and initial Gross Asset Value shall be taken into account under the “traditional method” as
described in Regulations Section 1.704-3(b). With respect to other properties contributed to the Partnership, the Partnership shall account for such variation under any method consistent with Section 704(c) of the Code and the applicable regulations
as chosen by the General Partner. In the event the Gross Asset Value of any Partnership asset is adjusted pursuant to subparagraph (b) of the definition of Gross Asset Value (provided in Article 1), subsequent allocations of Tax Items with
respect to such asset shall take account of the variation, if any, between the adjusted basis of such asset and its Gross Asset Value in the same manner as under Section 704(c) of the Code and the applicable regulations consistent with the
requirements of Regulations Section 1.704-1(b)(2)(iv)(g) using any method approved under Section 704(c) of the Code and the applicable regulations as chosen by the General Partner, provided, however, that the “traditional
method” as described in Regulations Section 1.704-3(b) shall be used with respect to Partnership Property that is contributed to the Partnership in connection with the General Partner’s initial public offering or pursuant to the
Partnership’s exercise of rights under any Option Agreement or ROFO Agreement.

that, as long as the General Partner has determined to continue to qualify as a REIT, the Partnership may not engage in any such formation, acquisition or contribution that could cause the General Partner to fail to qualify as a REIT;

  
 (11) the control of any matters affecting the rights and
obligations of the Partnership, including the settlement, compromise, submission to arbitration or any other form of dispute resolution, or abandonment of, any claim, cause of action, liability, debt or damages, due or owing to or from the

 (20) the making, execution and delivery of any and all deeds, leases, notes, deeds to secure debt, mortgages, deeds of trust, security agreements,

 (22) the distribution of cash to acquire Common Units held by a Limited Partner in connection with a Limited Partner’s exercise of its Redemption Right under Section 8.6 hereof; 
  
 (23) the amendment and restatement of Exhibit A hereto to reflect
accurately at all times the Capital Contributions and Percentage Interests of the Partners as the same are adjusted from time to time to the extent necessary to reflect redemptions, Capital Contributions, the issuance of Partnership Units, the
admission of any Additional Limited Partner or any Substituted Limited Partner or otherwise, which amendment and restatement, notwithstanding anything in this Agreement to the contrary, shall not be deemed an amendment to this Agreement, as long as
the matter or event being reflected in Exhibit A hereto otherwise is authorized by this Agreement; 
  
 (24) the taking of any and all acts and things necessary or prudent to ensure that the Partnership will not be classified as a “publicly traded
partnership” taxable as a corporation under Section 7704 of the Code; and 
  
 (25) the delegation to another Person of any powers now or hereafter granted to the General Partner. 
  
 B. Each of the Limited Partners agrees that the General Partner is authorized to execute, deliver and perform the above-mentioned agreements and
transactions on behalf of the Partnership without any further act, approval or vote of the Partners, notwithstanding any other provisions of this Agreement (except as provided in Section 7.3 or 11.2), the Act or any applicable law,
rule or regulation to the fullest extent permitted under the Act or other applicable law, rule or regulation. The execution, delivery or performance by the General Partner or the Partnership of any agreement authorized or permitted under this
Agreement shall not constitute a breach by the General Partner of any duty that the General Partner may owe the Partnership or the Limited Partners or any other Persons under this Agreement or of any duty stated or implied by law or equity.

  

 41 

 C. At all times from and after the date hereof, the General Partner may cause the Partnership to obtain
and maintain (i) casualty, liability and other insurance on the properties of the Partnership and (ii) liability insurance for the benefit of any or all Indemnitees. 
  
 D. At all times from and after the date hereof, the General Partner may cause the Partnership to establish and maintain
working capital and other reserves in such amounts as the General Partner, in its sole and absolute discretion, deems appropriate and reasonable from time to time. 
  
 E. In exercising its authority under this Agreement, the General Partner may, but shall be under no obligation to, take into
account the tax consequences to any Partner (including the General Partner) of any action taken (or not taken) by the General Partner. The General Partner and the Partnership shall not have liability to a Partner under this Agreement as a result of
an income tax liability incurred by such Limited Partner as a result of an action (or inaction) by the General Partner pursuant to its authority under this Agreement. 
  
 F. Except as otherwise provided herein, to the extent the duties of the General Partner require expenditures of funds to be
paid to third parties, the General Partner shall not have any obligations hereunder except to the extent that Partnership funds are reasonably available to it for the performance of such duties, and nothing herein contained shall be deemed to
authorize or require the General Partner, in its capacity as such, to expend its individual funds for payment to third parties or to undertake any individual liability or obligation on behalf of the Partnership. 
  
 Section 7.2 Certificate of Limited Partnership 
  
 To the extent that such action is determined by the General Partner to be
reasonable and necessary or appropriate, the General Partner shall file amendments to and restatements of the Certificate and do all the things to maintain the Partnership as a limited partnership (or a partnership in which the limited partners have
limited liability) under the laws of the State of Maryland and to maintain the Partnership’s qualification to do business as a foreign limited partnership in each other state, the District of Columbia or other jurisdiction, in which the
Partnership may elect to do business or own property. Subject to the terms of Section 8.5.A(4), the General Partner shall not be required, before or after filing, to deliver or mail a copy of the Certificate or any amendment thereto to any
Limited Partner. The General Partner shall use all reasonable efforts to cause to be filed such other certificates or documents as may be reasonable and necessary or appropriate for the formation, continuation, qualification and operation of a
limited partnership (or a partnership in which the limited partners have limited liability) in the State of Maryland, any other state, or the District of Columbia or other jurisdiction, in which the Partnership may elect to do business or own
property. 
  
 Section 7.3 Restrictions on General Partner’s Authority

  
 A. The General Partner may not take any action in
contravention of an express prohibition or limitation of this Agreement without the written Consent of the Limited Partners and may not (i) perform any act that would subject a Limited Partner to liability as a general partner in any jurisdiction or
any liability not contemplated herein or under the Act; or (ii) enter 

  

 42 

 
into any contract, mortgage, loan or other agreement that prohibits or restricts, or has the effect of prohibiting or restricting, the ability of a Limited
Partner to exercise its rights to a Redemption as provided in Section 8.6, except in each case with the written consent of such Limited Partner. 
  
 B. The General Partner shall not, without the prior Consent of the Limited Partners, or except as provided in Section 7.3.C, amend, modify or
terminate this Agreement. 
  
 C. Notwithstanding Section
7.3.B, the General Partner shall have the exclusive power to amend this Agreement as may be required to facilitate or implement any of the following purposes: 
  
 (1) to add to the obligations of the General Partner or surrender any right or power granted to the General Partner or any
Affiliate of the General Partner for the benefit of the Limited Partners; 
  
 (2) to reflect the issuance of additional Partnership Interests pursuant to Sections 4.3, 4.4, 4.5, 5.4 and 6.2.B or the admission, substitution, termination, or withdrawal of
Partners in accordance with this Agreement (which may be effected through the replacement of Exhibit A with an amended Exhibit A); 
  
 (3) to set forth or amend the designations, rights, powers, duties, and preferences of the holders of any additional Partnership Interests issued pursuant
to Article 4; 
  
 (4) to reflect a change that is of an
inconsequential nature and does not adversely affect the Limited Partners in any material respect, or to cure any ambiguity, correct or supplement any provision in this Agreement not inconsistent with law or with other provisions, or make other
changes with respect to matters arising under this Agreement that will not be inconsistent with law or with the provisions of this Agreement; 
  
 (5) to satisfy any requirements, conditions, or guidelines contained in any order, directive, opinion, ruling or regulation of a federal or state agency
or contained in federal or state law; 
  
 (6) to reflect such
changes as are reasonably necessary for the General Partner to maintain its status as a REIT, including changes which may be necessitated due to a change in applicable law (or an authoritative interpretation thereof) or a ruling of the IRS; and

  
 (7) to modify, as set forth in the definition of
“Capital Account,” the manner in which Capital Accounts are computed. 
  
 The General Partner will provide notice to the Limited Partners when any action under this Section 7.3.C is taken. 
  
 D. Notwithstanding Sections 7.3.B and 7.3.C, this Agreement shall not be amended with respect to any Partner adversely affected, and no
action may be taken by the General Partner, without the Consent of such Partner adversely affected if such amendment or action would (i) convert a Limited Partner’s interest in the Partnership into a general partner’s interest (except as
the result of the General Partner acquiring such interest), (ii) modify the limited 

  

 43 

 
liability of a Limited Partner, (iii) alter rights of the Partner to receive distributions pursuant to Article 5, Section 13.2.A(4) or
Article 16 or the allocations specified in Article 6 (except as permitted pursuant to Sections 4.3, 4.4, 4.5, 5.4, 6.2.B and Section 7.3.C(3)), (iv) adversely alter or modify the rights to a
Redemption or the REIT Shares Amount as set forth in Section 8.6, and related definitions hereof, (v) alter the protections of the Limited Partners as set forth in Section 11.2.B or (vi) amend this Section 7.3.D. Further, no
amendment may alter the restrictions on the General Partner’s authority set forth elsewhere in this Section 7.3 without the Consent specified in such section. This Section 7.3D does not require unanimous consent of all Partners
adversely affected unless the amendment is to be effective against all partners adversely affected. 
  
 Section 7.4 Reimbursement of the General Partner 
  
 A. Except as provided in this Section 7.4 and elsewhere in this Agreement (including the provisions of Articles 5 and 6 regarding distributions, payments and allocations to which it may be
entitled), the General Partner shall not be compensated for its services as general partner of the Partnership. 
  
 B. The Partnership shall be responsible for and shall pay all expenses relating to the Partnership’s and the General Partner’s organization, the
ownership of its assets and its operations. The General Partner is hereby authorized to cause the Partnership to pay compensation for accounting, administrative, legal, technical, management and other services rendered to the Partnership. Except to
the extent provided in this Agreement, the General Partner and its Affiliates shall be reimbursed on a monthly basis, or such other basis as the General Partner may determine in its sole and absolute discretion, for all expenses that the General
Partner and its Affiliates incur relating to the ownership and operation of, or for the benefit of, the Partnership (including, without limitation, administrative expenses); provided, that the amount of any such reimbursement shall be
reduced by any interest earned by the General Partner with respect to bank accounts or other instruments or accounts held by it on behalf of the Partnership. The Partners acknowledge that all such expenses of the General Partner are deemed to be for
the benefit of the Partnership. Such reimbursement shall be in addition to any reimbursement made as a result of indemnification pursuant to Section 7.7 hereof. In the event that certain expenses are incurred for the benefit of the
Partnership and other entities (including the General Partner), such expenses will be allocated to the Partnership and such other entities in such a manner as the General Partner in its sole and absolute discretion deems fair and reasonable. All
payments and reimbursements hereunder shall be characterized for federal income tax purposes as expenses of the Partnership incurred on its behalf, and not as expenses of the General Partner. 
  
 C. If the General Partner shall elect to purchase from its stockholders REIT
Shares for the purpose of delivering such REIT Shares to satisfy an obligation under any dividend reinvestment program adopted by the General Partner, any employee stock purchase plan adopted by the General Partner, or any similar obligation or
arrangement undertaken by the General Partner in the future or for the purpose of retiring such REIT Shares, the purchase price paid by the General Partner for such REIT Shares and any other expenses incurred by the General Partner in connection
with such purchase shall be considered expenses of the Partnership and shall be advanced by the Partnership to the General Partner or reimbursed by the Partnership to the General Partner, subject to the condition that: (i) if such REIT Shares

  

 44 

 
subsequently are sold by the General Partner, the General Partner shall pay to the Partnership any proceeds received by the General Partner for such REIT
Shares (which sales proceeds shall include the amount of dividends reinvested under any dividend reinvestment or similar program; provided, that a transfer of REIT Shares for Common Units pursuant to Section 8.6 would not be
considered a sale for such purposes); and (ii) if such REIT Shares are not retransferred by the General Partner within thirty (30) days after the purchase thereof, or the General Partner otherwise determines not to retransfer such REIT Shares, the
General Partner, shall cause the Partnership to redeem a number of Common Units held by the General Partner equal to the number of such REIT Shares, as adjusted (x) pursuant to Section 7.5 (in the event the General Partner acquires material
assets, other than on behalf of the Partnership) and (y) for stock dividends and distributions, stock splits and subdivisions, reverse stock splits and combinations, distributions of rights, warrants or options, and distributions of evidences of
indebtedness or assets relating to assets not received by the General Partner pursuant to a pro rata distribution by the Partnership (in which case such advancement or reimbursement of expenses shall be treated as having been made as a
distribution in redemption of such number of Common Units held by the General Partner). 
  
 D. As set forth in Section 4.3, the General Partner shall be treated as having made a Capital Contribution in the amount of all expenses that it incurs relating to the General Partner’s offering of REIT
Shares, other shares of capital stock of the General Partner or New Securities. 
  
 E. If and to the extent any reimbursements to the General Partner pursuant to this Section 7.4 constitute gross income of the General Partner (as opposed to the repayment of advances made by the General Partner
on behalf of the Partnership), such amounts shall constitute guaranteed payments within the meaning of Section 707(c) of the Code, shall be treated consistently therewith by the Partnership and all Partners, and shall not be treated as distributions
for purposes of computing the Partners’ Capital Accounts. 
  
 Section 7.5
Outside Activities of the General Partner 
  
 A. Except in
connection with a transaction authorized in Section 11.2, without the Consent of the Limited Partners, the General Partner shall not, directly or indirectly, enter into or conduct any business, other than in connection with the ownership,
acquisition and disposition of Partnership Interests as a General Partner and the management of the business of the Partnership, its operation as a public reporting company with a class (or classes) of securities registered under the Exchange Act,
its operation as a REIT and such activities as are incidental to the same. Except as otherwise expressly provided in this Section 7.5, without the Consent of the Limited Partners, the General Partner shall not, directly or indirectly,
participate in or otherwise acquire any interest in any real or personal property, except its General Partner Interest, its minority interest in any Subsidiary Partnership(s) that the General Partner holds in order to maintain such Subsidiary
Partnership’s status as a partnership, and such bank accounts, similar instruments or other short-term investments as it deems necessary to carry out its responsibilities contemplated under this Agreement and the Charter. In the event the
General Partner desires to contribute cash to any Subsidiary Partnership to acquire or maintain an interest of 1% or less in the capital of such partnership, the General Partner may acquire or maintain an interest of 1% or less in the capital of
such partnership, and the General Partner may acquire such cash from the Partnership as a loan or in exchange for a reduction in the General Partner’s Partnership Units, in an amount 

  

 45 

 
equal to the amount of such cash divided by the Fair Market Value of a REIT Share on the day such cash is received by the General Partner. Notwithstanding
the foregoing, the General Partner may acquire Properties or other assets in exchange for REIT Shares or cash, to the extent such Properties or other assets are immediately contributed by the General Partner to the Partnership, pursuant to the terms
described in Section 4.3.D. Any Limited Partner Interests acquired by the General Partner, whether pursuant to exercise by a Limited Partner of its right of Redemption, or otherwise, shall be automatically converted into a General Partner
Interest comprised of an identical number of Partnership Units with the same rights, priorities and preferences as the class or series so acquired. The General Partner may also own one-hundred percent (100%) of the stock or interests of one or more
Qualified REIT Subsidiaries or limited liability companies, respectively, provided that any such entity shall be subject to the limitations of this Section 7.5.A. If, at any time, the General Partner acquires material assets
(other than Partnership Interests or other assets on behalf of the Partnership), the definition of “REIT Shares Amount” and the definition of “Deemed Value of Partnership Interests” shall be adjusted, as reasonably
determined by the General Partner, to reflect the relative Fair Market Value of a share of capital stock of the General Partner relative to the Deemed Partnership Interest Value of the related Partnership Unit. The General Partner’s General
Partner Interest in the Partnership, its minority interest in any Subsidiary Partnership(s) (held directly or indirectly through a Qualified REIT Subsidiary) that the General Partner holds in order to maintain such Subsidiary Partnership’s
status as a partnership, and interests in such short-term liquid investments, bank accounts or similar instruments as the General Partner deems necessary to carry out its responsibilities contemplated under this Agreement and the Charter are
interests which the General Partner is permitted to acquire and hold for purposes of this Section 7.5.A. 
  
 B. In the event the General Partner exercises its rights under the Charter to purchase REIT Shares, other capital stock of the General Partner or New
Securities, as the case may be, then the General Partner shall cause the Partnership to purchase from it a number of Partnership Units equal to the number of REIT Shares, other capital stock of the General Partner or New Securities, as the case may
be, so purchased on the same terms that the General Partner purchased such REIT Shares, other capital stock of the General Partner or New Securities, as the case may be. 
  
 Section 7.6 Contracts with Affiliates 
  
 A. The Partnership may lend or contribute to, and borrow funds from, Persons in which it has an equity investment, and such Persons may borrow funds from,
and lend or contribute funds to, the Partnership, on terms and conditions established in the sole and absolute discretion of the General Partner. The foregoing authority shall not create any right or benefit in favor of any Person. 
  
 B. Except as provided in Section 7.5.A, the Partnership may transfer
assets to joint ventures, other partnerships, corporations or other business entities in which it is or thereby becomes a participant upon such terms and subject to such conditions consistent with this Agreement and applicable law as the General
Partner in its sole discretion deems advisable. 
  
 C. The General
Partner, in its sole and absolute discretion and without the approval of the Limited Partners, may propose and adopt on behalf of the Partnership employee benefit 

  

 46 

 
plans (including without limitation plans that contemplate the issuance of Profits Interests Units) funded by the Partnership for the benefit of employees of
the General Partner, the Partnership, Subsidiaries of the Partnership or any Affiliate of any of them in respect of services performed or to be performed, directly or indirectly, for the benefit of such entities. The General Partner also is
expressly authorized to cause the Partnership to issue to it Common Units corresponding to REIT Shares issued by the General Partner pursuant to any Stock Plan or any similar or successor plan and to repurchase such Partnership Units from the
General Partner to the extent necessary to permit the General Partner to repurchase such REIT Shares in accordance with such plan. 
  
 D. Except as expressly permitted by this Agreement, neither the General Partner nor any of its Affiliates shall sell, transfer or convey any property to,
or purchase any property from, the Partnership, directly or indirectly, except pursuant to transactions that are determined by the General Partner in good faith to be fair and reasonable. 
  
 E. The General Partner is expressly authorized to enter into, in the name and on behalf of the Partnership, a right of first
opportunity arrangement and other conflict avoidance agreements with various Affiliates of the Partnership and the General Partner, on such terms as the General Partner, in its sole and absolute discretion, believes are advisable. 
  
 Section 7.7 Indemnification 
  
 A. To the fullest extent permitted by law, the Partnership shall indemnify
an Indemnitee from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, settlements, and other amounts arising from any and all claims, demands, subpoenas,
requests for information, formal or informal investigations, actions, suits or proceedings, civil, criminal, administrative or investigative, that relate to the operations of the Partnership or the General Partner as set forth in this Agreement in
which any Indemnitee may be involved, or is threatened to be involved, as a party or otherwise, unless it is established that: (i) the act or omission of the Indemnitee was material to the matter giving rise to the proceeding and either was
committed in bad faith, constituted fraud or was the result of active and deliberate dishonesty; (ii) the Indemnitee actually received an improper personal benefit in money, property or services; or (iii) in the case of any criminal proceeding, the
Indemnitee had reasonable cause to believe that the act or omission was unlawful. Without limitation, the foregoing indemnity shall extend to any liability of any Indemnitee, pursuant to a loan guaranty or otherwise, for any indebtedness of the
Partnership or any Subsidiary of the Partnership (including, without limitation, any indebtedness which the Partnership or any Subsidiary of the Partnership has assumed or taken subject to), and the General Partner is hereby authorized and
empowered, on behalf of the Partnership, to enter into one or more indemnity agreements consistent with the provisions of this Section 7.7 in favor of any Indemnitee having or potentially having liability for any such indebtedness. The
termination of any proceeding by judgment, order or settlement does not create a presumption that the Indemnitee did not meet the requisite standard of conduct set forth in this Section 7.7.A. The termination of any proceeding by conviction
or upon a plea of nolo contendere or its equivalent, or any entry of an order of probation prior to judgment, creates a rebuttable presumption that the Indemnitee acted in a manner contrary to that specified in this Section 7.7.A. Any
indemnification pursuant to this Section 7.7 shall be made only out of the assets of 

  

 47 

 
the Partnership, and any insurance proceeds from liability policies covering the General Partner and any Indemnitee, and neither the General Partner nor any
Limited Partner shall have any obligation to contribute to the capital of the Partnership or otherwise provide funds to enable the Partnership to fund its obligations under this Section 7.7, except to the extent otherwise expressly agreed to
by such Partner and the Partnership. 
  
 B. Reasonable expenses
incurred by an Indemnitee who is a party to a proceeding or the recipient of a subpoena or request for information with respect to a proceeding to which such Indemnitee is not a party may be paid or reimbursed by the Partnership in advance of the
final disposition of the proceeding upon receipt by the Partnership of (i) a written affirmation by the Indemnitee of the Indemnitee’s good faith belief that the standard of conduct necessary for indemnification by the Partnership as authorized
in this Section 7.7 has been met, and (ii) a written undertaking by or on behalf of the Indemnitee to repay the amount if it shall ultimately be determined that the standard of conduct has not been met. 
  
 C. The indemnification provided by this Section 7.7 shall be in
addition to any other rights to which an Indemnitee or any other Person may be entitled under any agreement, pursuant to any vote of the Partners, as a matter of law or otherwise, and shall continue as to an Indemnitee who has ceased to serve in
such capacity unless otherwise provided in a written agreement pursuant to which such Indemnitee is indemnified. 
  
 D. The Partnership may, but shall not be obligated to, purchase and maintain insurance, on behalf of the Indemnitees and such other Persons as the General
Partner shall determine, against any liability that may be asserted against or expenses that may be incurred by such Person in connection with the Partnership’s activities, regardless of whether the Partnership would have the power to indemnify
such Person against such liability under the provisions of this Agreement. 
  
 E. For purposes of this Section 7.7, the Partnership shall be deemed to have requested an Indemnitee to serve as fiduciary of an employee benefit plan whenever the performance by it of its duties to the
Partnership also imposes duties on, or otherwise involves services by, it to the plan or participants or beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect to an employee benefit plan pursuant to applicable law shall
constitute fines within the meaning of Section 7.7; and actions taken or omitted by the Indemnitee with respect to an employee benefit plan in the performance of its duties for a purpose reasonably believed by it to be in the interest of the
participants and beneficiaries of the plan shall be deemed to be for a purpose which is not opposed to the best interests of the Partnership. 
  
 F. In no event may an Indemnitee subject the Limited Partners to personal liability by reason of the indemnification provisions set forth in this
Agreement. 
  
 G. An Indemnitee shall not be denied
indemnification in whole or in part under this Section 7.7 because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement.

  

 48 

 H. The provisions of this Section 7.7 are for the benefit of the Indemnitees, their heirs,
successors, assigns and administrators and shall not be deemed to create any rights for the benefit of any other Persons. Any amendment, modification or repeal of this Section 7.7 or any provision hereof shall be prospective only and shall
not in any way affect the limitations on the Partnership’s liability to any Indemnitee under this Section 7.7 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to
matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted. 
  
 I. If and to the extent any reimbursements to the General Partner pursuant to this Section 7.7 constitute gross income of the General Partner (as
opposed to the repayment of advances made by the General Partner on behalf of the Partnership) such amounts shall constitute guaranteed payments within the meaning of Section 707(c) of the Code, shall be treated consistently therewith by the
Partnership and all Partners, and shall not be treated as distributions for purposes of computing the Partners’ Capital Accounts. 
  
 J. Any indemnification hereunder is subject to, and limited by, the provisions of Section 10-107 of the Act. 
  
 K. In the event the Partnership is made a party to any litigation or
otherwise incurs any loss or expense as a result of or in connection with any Partner’s personal obligations or liabilities unrelated to Partnership business, such Partner shall indemnify and reimburse the Partnership for all such loss and
expense incurred, including legal fees, and the Partnership interest of such Partner may be charged therefor. The liability of a Partner under this Section 7.7.K shall not be limited to such Partner’s Partnership Interest, but shall be
enforceable against such Partner personally. 
  
 Section 7.8 Liability of the
General Partner 
  
 A. Notwithstanding anything to the
contrary set forth in this Agreement, none of the General Partner nor any of its officers, directors, agents or employees shall be liable or accountable in damages or otherwise to the Partnership, any Partners or any Assignees, or their successors
or assigns, for losses sustained, liabilities incurred or benefits not derived as a result of errors in judgment or mistakes of fact or law or any act or omission if the General Partner acted in good faith. 
  
 B. The Limited Partners expressly acknowledge that the General Partner is
acting for the benefit of the Partnership, the Limited Partners and the General Partner’s stockholders collectively. Neither the General Partner generally nor the board of directors of the General Partner specifically is under any obligation to
give priority to the separate interests of the Limited Partners or the General Partner’s stockholders (including, without limitation, the tax consequences to Limited Partners or Assignees or to stockholders) in deciding whether to cause the
Partnership to take (or decline to take) any actions. If there is a conflict between the interests of the stockholders of the General Partner on one hand and the Limited Partners on the other, the General Partner shall endeavor in good faith to
resolve the conflict in a manner not adverse to either the stockholders of the General Partner or the Limited Partners; provided, however, that for so long as the General Partner owns a controlling interest in the Partnership,
any such conflict 

  

 49 

 
that cannot be resolved in a manner not adverse to either the stockholders of the General Partner or the Limited Partners shall be resolved in favor of the
stockholders of the General Partner. The General Partner shall not be liable under this Agreement to the Partnership or to any Partner for monetary damages for losses sustained, liabilities incurred, or benefits not derived by Limited Partners in
connection with such decisions; provided, that the General Partner has acted in good faith. 
  
 C. Subject to its obligations and duties as General Partner set forth in Section 7.1.A, the General Partner may exercise any of the powers granted
to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through its agents. The General Partner shall not be responsible for any misconduct or negligence on the part of any such agent appointed by it
in good faith. 
  
 D. Any amendment, modification or repeal of
this Section 7.8 or any provision hereof shall be prospective only and shall not in any way affect the limitations on the liability of the General Partner and any of its officers, directors, agents and employee’s liability to the
Partnership and the Limited Partners under this Section 7.8 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such
amendment, modification or repeal, regardless of when such claims may arise or be asserted. 
  
 Section 7.9 Other Matters Concerning the General Partner 
  
 A. The General Partner may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, bond, debenture, or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties. 
  
 B. The General Partner may consult with legal counsel, accountants,
appraisers, management consultants, investment bankers and other consultants and advisers selected by it, and any act taken or omitted to be taken in reliance upon the opinion of such Persons as to matters which such General Partner reasonably
believes to be within such Person’s professional or expert competence shall be conclusively presumed to have been done or omitted in good faith and in accordance with such opinion. 
  
 C. The General Partner shall have the right, in respect of any of its powers or obligations hereunder, to act through any of
its duly authorized officers and a duly appointed attorney or attorneys-in-fact. Each such attorney shall, to the extent provided by the General Partner in the power of attorney, have full power and authority to do and perform all and every act and
duty which is permitted or required to be done by the General Partner hereunder. 
  
 D. Notwithstanding any other provisions of this Agreement or any non-mandatory provision of the Act, any action of the General Partner on behalf of the Partnership or any decision of the General Partner to refrain
from acting on behalf of the Partnership, undertaken in the good faith belief that such action or omission is necessary or advisable in order to protect the ability of the General Partner, for so long as the General Partner has determined to qualify
as a REIT, to (i) continue to qualify as a REIT or (ii) avoid the General Partner incurring any taxes under Section 857 or Section 4981 of the Code, is expressly authorized under this Agreement and is deemed approved by all of the Limited Partners.

  

 50 

 Section 7.10 Title to Partnership Assets 
  
 Title to Partnership assets, whether real, personal or mixed and whether tangible or intangible, shall be deemed to be owned
by the Partnership as an entity, and no Partners, individually or collectively, shall have any ownership interest in such Partnership assets or any portion thereof. Title to any or all of the Partnership assets may be held in the name of the
Partnership, the General Partner or one or more nominees, as the General Partner may determine, including Affiliates of the General Partner. The General Partner hereby declares and warrants that any Partnership assets for which legal title is held
in the name of the General Partner or any nominee or Affiliate of the General Partner shall be held by the General Partner for the use and benefit of the Partnership in accordance with the provisions of this Agreement; provided,
however, that the General Partner shall use its best efforts to cause beneficial and record title to such assets to be vested in the Partnership as soon as reasonably practicable. All Partnership assets shall be recorded as the property of
the Partnership in its books and records, irrespective of the name in which legal title to such Partnership assets is held. 
  
 Section 7.11 Reliance by Third Parties 
  
 Notwithstanding anything to the contrary in this Agreement, any Person dealing with the Partnership shall be entitled to assume that the General Partner
has full power and authority to encumber, sell or otherwise use in any manner any and all assets of the Partnership and to enter into any contracts on behalf of the Partnership, and such Person shall be entitled to deal with the General Partner as
if it were the Partnership’s sole party in interest, both legally and beneficially. Each Limited Partner hereby waives any and all defenses or other remedies which may be available against such Person to contest, negate or disaffirm any action
of the General Partner in connection with any such dealing. In no event shall any Person dealing with the General Partner or its representatives be obligated to ascertain that the terms of this Agreement have been complied with or to inquire into
the necessity or expedience of any act or action of the General Partner or its representatives. Each and every certificate, document or other instrument executed on behalf of the Partnership by the General Partner or its representatives shall be
conclusive evidence in favor of any and every Person relying thereon or claiming thereunder that (i) at the time of the execution and delivery of such certificate, document or instrument, this Agreement was in full force and effect, (ii) the Person
executing and delivering such certificate, document or instrument was duly authorized and empowered to do so for and on behalf of the Partnership and (iii) such certificate, document or instrument was duly executed and delivered in accordance with
the terms and provisions of this Agreement and is binding upon the Partnership. 
  
 ARTICLE 8. 
 RIGHTS AND OBLIGATIONS OF LIMITED PARTNERS

 No Limited Partner or Assignee (other than the General Partner, any of its Affiliates or any officer, director, employee,
partner, agent or trustee of the General Partner, the Partnership or any of their Affiliates, in their capacity as such) shall take part in the operations, management or control (within the meaning of the Act) of the Partnership’s business
transact any business in the Partnership’s name or have the power to sign documents for or otherwise bind the Partnership. The transaction of any such business by the General Partner, any of its Affiliates or any officer, director, employee,
partner, agent or trustee of the General Partner, the Partnership or any of their Affiliates, in their capacity as such, shall not affect, impair or eliminate the limitations on the liability of the Limited Partners or Assignees under this
Agreement. 
  
 Section 8.3 Outside Activities of Limited Partners

  
 Subject to any agreements entered into by a Limited Partner
or its Affiliates with the General Partner, Partnership or a Subsidiary, any Limited Partner and any officer, director, employee, agent, trustee, Affiliate or stockholder of any Limited Partner shall be entitled to and may have business interests
and engage in business activities in addition to those relating to the Partnership, including business interests and activities in direct competition with the Partnership or that are enhanced by the activities of the Partnership. Neither the
Partnership nor any Partners shall have any rights by virtue of this Agreement in any business ventures of any Limited Partner or Assignee. Subject to such agreements, none of the Limited Partners nor any other Person shall have any rights by virtue
of this Agreement or the partnership relationship established hereby in any business ventures of any other Person, other than the Limited Partners benefiting from the business conducted by the General Partner, and such Person shall have no
obligation pursuant to this Agreement to offer any interest in any such business ventures to the Partnership, any Limited Partner or any such other Person, even if such opportunity is of a character which, if presented to the Partnership, any
Limited Partner or such other Person, could be taken by such Person. 
  
 Section
8.4 Return of Capital 
  
 Except pursuant to the rights of
Redemption set forth in Section 8.6, no Limited Partner shall be entitled to the withdrawal or return of his or her Capital Contribution, except to the extent of distributions made pursuant to this Agreement or upon termination of the
Partnership as provided herein. Except as expressly set forth herein, no Limited Partner or Assignee shall have priority over any other Limited Partner or Assignee either as to the return of Capital Contributions or as to profits, losses,
distributions or credits. 
  
 Section 8.5 Rights of Limited Partners Relating
to the Partnership 
  
 A. In addition to other rights
provided by this Agreement or by the Act, and except as limited by Section 8.5.C, each Limited Partner shall have the right, for a purpose reasonably related to such Limited Partner’s interest as a limited partner in the Partnership,
upon written demand with a statement of the purpose of such demand and at such Limited Partner’s expense: 
  
 (1) to obtain a copy of the most recent annual and quarterly reports filed with the Securities and Exchange Commission by the General Partner pursuant to
the Exchange Act, and each communication sent to the stockholders of the General Partner; 
  

 52 

 (2) to obtain a copy of the Partnership’s federal, state and local income tax returns for each
Partnership Year; 
  
 (3) to obtain a current list of the name and
last known business, residence or mailing address of each Partner; 
  
 (4) to obtain a copy of this Agreement and the Certificate and all amendments thereto, together with executed copies of all powers of attorney pursuant to which this Agreement, the Certificate and all amendments thereto have been executed;
and 
  
 (5) to obtain true and full information regarding the
amount of cash and a description and statement of any other property or services contributed by each Partner and which each Partner has agreed to contribute in the future, and the date on which each became a Partner. 
  
 B. The Partnership shall notify each Limited Partner in writing of any
adjustment made in the calculation of the REIT Shares Amount within a reasonable time after the date such change becomes effective. 
  
 C. Notwithstanding any other provision of this Section 8.5, the General Partner may keep confidential from the Limited Partners, for such period of
time as the General Partner determines in its sole and absolute discretion to be reasonable, any information that (i) the General Partner believes to be in the nature of trade secrets or other information the disclosure of which the General Partner
in good faith believes is not in the best interests of the Partnership or (ii) the Partnership or the General Partner is required by law or by agreements with unaffiliated third parties to keep confidential. 
  
 Section 8.6 Limited Partner Redemption Rights 
  
 A. On or after the date fourteen (14) months after (i) the Effective Date,
with respect to the Common Units acquired prior to, on or contemporaneously with the Effective Date, (ii) the Option Agreement Effective Date, with respect to the Common Units received pursuant to the Option Agreement, (iii) the ROFO Agreement
Effective Date, with respect to the Common Units received pursuant to the ROFO Agreement, and (iv) the date of issuance of any other Common Units, in each case unless a different date is expressly provided in an agreement entered into between the
Partnership and any Limited Partner, each Limited Partner shall have the right (subject to the terms and conditions set forth herein and in any other such agreement, as applicable) to require the Partnership to redeem all or a portion of the Common
Units held by such Limited Partner (such Common Units being hereafter referred to as “Tendered Units”) in exchange for the Cash Amount (a “Redemption”); provided that the terms of such Common Units do
not provide that such Common Units are not entitled to a right of Redemption. Unless otherwise expressly provided in this Agreement or in a separate agreement entered into between the Partnership and the holders of such Common Units, all Common
Units shall be entitled to a right of Redemption hereunder. The Tendering Partner shall have no right, with respect to any 

  

 53 

 
Common Units so redeemed, to receive any distributions paid on or after the Specified Redemption Date. Any Redemption shall be exercised pursuant to a Notice
of Redemption delivered to the General Partner by the Limited Partner who is exercising the right (the “Tendering Partner”). The Cash Amount shall be payable in accordance with the instructions set forth in the Notice of Redemption
to the Tendering Partner within ten (10) days of the Specified Redemption Date, except as provided below. 
  
 B. REIT Share Election 
  
 (1) Notwithstanding Section 8.6.A above, if a Limited Partner has delivered to the General Partner a Notice of Redemption then the General Partner
may, in its sole and absolute discretion, (subject to the limitations on ownership and transfer of REIT Shares set forth in the Charter) elect to acquire some or all of the Tendered Units from the Tendering Partner in exchange for the REIT Shares
Amount (as of the Specified Redemption Date) and, if the General Partner so elects, the Tendering Partner shall sell the Tendered Units to the General Partner in exchange for the REIT Shares Amount. In such event, the Tendering Partner shall have no
right to cause the Partnership to redeem such Tendered Units. The General Partner shall promptly give such Tendering Partner written notice of its election, and subject to Section 8.6.C below, the Tendering Partner may elect to withdraw its
redemption request at any time prior to the receipt of cash pursuant to Section 8.6.A or REIT Shares Amount pursuant to this Section 8.6.B by such Tendering Partner. 
  
 (2) The REIT Shares Amount, if applicable, shall be delivered as duly authorized, validly issued, fully paid and
nonassessable REIT Shares and, if applicable, free of any pledge, lien, encumbrance or restriction, other than those provided in the Charter, the Bylaws of the General Partner, the Securities Act, relevant state securities or blue sky laws and any
applicable registration rights agreement with respect to such REIT Shares entered into by the Tendering Partner. Notwithstanding any delay in such delivery (but subject to Section 8.6.E), the Tendering Partner shall be deemed the owner of
such REIT Shares for all purposes, including without limitation, rights to vote or consent, and receive dividends, as of the Specified Redemption Date. In addition, the REIT Shares for which the Common Units might be exchanged shall also bear a
legend which generally provides the following: 
  
 THE SHARES OF
COMMON STOCK REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON BENEFICIAL AND CONSTRUCTIVE OWNERSHIP AND TRANSFER FOR THE PURPOSE OF THE CORPORATION’S MAINTENANCE OF ITS STATUS AS A REAL ESTATE INVESTMENT TRUST (“REIT”)
UNDER THE INTERNAL REVENUE CODE OF 1986, AS AMENDED (THE “CODE”). SUBJECT TO CERTAIN FURTHER RESTRICTIONS AND EXCEPT AS EXPRESSLY PROVIDED IN THE CORPORATION’S ARTICLES OF AMENDMENT AND RESTATEMENT, (i) NO PERSON MAY BENEFICIALLY OR
CONSTRUCTIVELY OWN SHARES OF CAPITAL STOCK OF THE CORPORATION IN EXCESS OF 9.8% OF THE VALUE OF THE TOTAL OUTSTANDING SHARES OF CAPITAL STOCK OF THE CORPORATION AND NO PERSON MAY BENEFICIALLY OR CONSTRUCTIVELY OWN SHARES OF THE CORPORATION’S
COMMON STOCK IN EXCESS OF 9.8% (BY VALUE OR BY NUMBER OF SHARES, WHICHEVER IS MORE RESTRICTIVE) OF THE OUTSTANDING COMMON STOCK OF THE CORPORATION; (ii) NO PERSON MAY 

  

 54 

 
BENEFICIALLY OR CONSTRUCTIVELY OWN SHARES OF CAPITAL STOCK THAT WOULD RESULT IN THE CORPORATION BEING “CLOSELY HELD” UNDER SECTION 856(h) OF THE
CODE OR OTHERWISE CAUSE THE CORPORATION TO FAIL TO QUALIFY AS A REIT; AND (iii) NO PERSON MAY TRANSFER SHARES OF CAPITAL STOCK IF SUCH TRANSFER WOULD RESULT IN THE CAPITAL STOCK OF THE CORPORATION BEING OWNED BY FEWER THAN 100 PERSONS. ANY PERSON
WHO BENEFICIALLY OR CONSTRUCTIVELY OWNS OR ATTEMPTS TO BENEFICIALLY OR CONSTRUCTIVELY OWN SHARES OF CAPITAL STOCK IN VIOLATION OF THE ABOVE LIMITATIONS MUST IMMEDIATELY NOTIFY THE CORPORATION. IF ANY OF THE RESTRICTIONS ON TRANSFER OR OWNERSHIP SET
FORTH IN (i) OR (ii) IS VIOLATED, THE SHARES OF COMMON STOCK REPRESENTED HEREBY WILL BE AUTOMATICALLY TRANSFERRED TO THE TRUSTEE OF A TRUST FOR THE BENEFIT OF ONE OR MORE CHARITABLE BENEFICIARIES, AND ANY TRANSFER THAT WOULD RESULT IN THE CAPITAL
STOCK OF THE CORPORATION BEING OWNED BY FEWER THAN 100 PERSONS SHALL BE VOID AB INITIO. IN ADDITION, THE CORPORATION MAY REDEEM SHARES UPON THE TERMS AND CONDITIONS SPECIFIED BY THE BOARD OF DIRECTORS IN ITS SOLE DISCRETION IF THE
BOARD OF DIRECTORS DETERMINES THAT OWNERSHIP OR A TRANSFER OR OTHER EVENT MAY VIOLATE THE RESTRICTIONS DESCRIBED ABOVE. FURTHERMORE, UPON THE OCCURRENCE OF CERTAIN EVENTS, ATTEMPTED TRANSFERS IN VIOLATION OF THE RESTRICTIONS DESCRIBED ABOVE MAY BE
VOID AB INITIO. ALL TERMS IN THIS LEGEND THAT ARE DEFINED IN THE CHARTER OF THE CORPORATION SHALL HAVE THE MEANINGS ASCRIBED TO THEM IN THE CHARTER OF THE CORPORATION, AS THE SAME MAY BE AMENDED FROM TIME TO TIME, A COPY OF WHICH, INCLUDING THE
RESTRICTIONS ON TRANSFER AND OWNERSHIP, WILL BE FURNISHED TO EACH HOLDER OF SHARES OF COMMON STOCK ON REQUEST AND WITHOUT CHARGE. REQUESTS FOR SUCH A COPY MAY BE DIRECTED TO THE SECRETARY OF THE CORPORATION AT ITS PRINCIPAL OFFICE. 
  
 C. Stock Offering Funding Option 
  
 (1) (a) Notwithstanding Section 8.6.A or Section 8.6.B above,
if a Limited Partner has delivered to the General Partner a Notice of Redemption with respect to Excess Units, and (i) the number of Excess Units plus the number of Tendered Units such Limited Partner agrees to treat as Excess Units (the
“Offering Units”) exceeds (A) 9.8% of the REIT Shares, calculated in accordance with the methodology for calculating the percentage of ownership of a Person for purposes of the ownership limit pursuant to Article VI of the Charter
(subject to adjustment in connection with any Adjustment Event), and (B) $50,000,000 gross value based on a Partnership Unit price equal to the REIT Share Market Value, and (ii) the General Partner is eligible to file a registration statement under
Form S-3 (or any successor form similar thereto), then the General Partner may, at its election, either (x) cause the Partnership to redeem the Offering Units with the proceeds of an offering, whether registered under the Securities Act or exempt
from such registration, underwritten, offered and sold directly to investors or through agents or other intermediaries, or otherwise distributed (a “Stock Offering Funding”) of a number of REIT Shares (“Offered
Shares”) equal to the REIT Shares Amount with respect to the Offering Units pursuant to the terms of this Section 8.6.C; or (y) cause the 

  

 55 

 
Partnership to pay the Cash Amount with respect to the Excess Units pursuant to the terms of Section 8.6.A; or (z) acquire the Excess Units in
exchange for the REIT Shares Amount pursuant to the terms of Section 8.6.B, but only if the Tendering Partner provides the General Partner with any representations or undertakings which the General Partner has determined, in its sole and
absolute discretion, are sufficient to prevent a violation of the Charter. In the event that the General Partner fails to give notice of its exercise of the election described in clause (i) above within the period of time specified in Section
8.6.B for an election to deliver the REIT Share Amount, it will be deemed to have elected not to purchase the Tendered Units through a Stock Offering Funding. 
  
 (b) In the event that the General Partner elects a Stock Offering Funding with respect to a Notice of Redemption, it may at
such time give notice (a “Single Funding Notice”) of such election to all Limited Partners and require that all Limited Partners elect whether or not to effect a Redemption to be funded through such Stock Offering Funding. In the
event a Limited Partner elects to effect such a Redemption, it shall give notice thereof and of the number of Common Units to be made subject thereto in writing to the General Partner within 10 Business Days after receipt of the Single Funding
Notice, and such Limited Partner shall be treated as a Tendering Partner for all purposes of this Section 8.6.C. In the event that a Limited Partner does not so elect, it shall be deemed to have waived its right to effect a Redemption for the
current Twelve-Month Period, except that it may effect a Redemption for no more than 1.0% of the REIT Shares, calculated in accordance with the methodology for calculating the percentage of ownership of a Person for purposes of the ownership limit
pursuant to Article VI of the Charter (subject to adjustment in connection with any Adjustment Event) during such Twelve-Month Period. 
  
 (2) In the event that the General Partner elects a Stock Offering Funding, on the Specified Redemption Date determined pursuant to the proviso in the
definition thereof it shall purchase each Offering Unit that is still a Tendered Unit on such date for cash in immediately available funds in the amount (the “Stock Offering Funding Amount”) equal to the lesser of (i) the Cash
Amount per Common Unit, calculated pursuant to Section 8.6.A as of the original Specified Redemption Date assuming the General Partner did not elect to conduct a Stock Offering Funding pursuant to Section 8.6.C (the “Base
Amount”) or (ii) the net proceeds per Offered Share received by the General Partner from the Stock Offering Funding, determined after deduction of reasonable expenses related thereto, including underwriting discounts and commissions, legal
and accounting fees and expenses, Securities and Exchange Commission registration fees, state blue sky and securities laws fees and expenses, printing expenses, NASD filing fees and listing fees (the “Net Proceeds”). 
  
 (3) If the General Partner elects a Stock Offering Funding, the following
additional terms and conditions shall apply: 
  
 (a) As soon as
practicable after the General Partner gives the Tendering Partner notice of its election pursuant to Section 8.6.C(1)(a)(i), the General Partner shall use its reasonable efforts to effect as promptly as possible a registration, qualification
or compliance (including, without limitation, the execution of an undertaking to file post-effective amendments, appropriate qualifications under applicable blue sky or other state securities laws and appropriate compliance with applicable
regulations issued under the Securities Act and any 

  

 56 

 
other governmental requirements or regulations) as would permit or facilitate the sale and distribution of the Offered Shares; provided, that,
the General Partner shall not by reason hereof, be required to submit to jurisdiction or taxation, or qualify to do business in any jurisdiction in which such submission or qualification would not be otherwise required; provided,
further, that if the General Partner shall deliver a certificate to the Tendering Partner stating that the General Partner has determined in the good faith judgment of the Board of Directors of the General Partner that such filing,
registration or qualification would require disclosure of material non-public information, the disclosure of which would have a material adverse effect on the General Partner, then the General Partner may delay making any filing or delay the
effectiveness of any registration or qualification for the shorter of (a) the period ending on the date upon which such information is disclosed to the public or ceases to be material or (b) an aggregate period of ninety (90) days in connection with
any Stock Offering Funding. 
  
 (b) The General Partner shall
advise each Tendering Partner, regularly and promptly upon any request, of the status of the Stock Offering Funding process, including the timing of all filings, the selection of and understandings with underwriters, agents, dealers and brokers, the
nature and contents of all communications with the Securities and Exchange Commission and other governmental bodies, the expenses related to the Stock Offering Funding as they are being incurred, the nature of marketing activities, and any other
matters reasonably related to the timing, price and expenses relating to the Stock Offering Funding and the compliance by the General Partner with its obligations with respect thereto. In addition, the General Partner and each Tendering Partner may,
but shall be under no obligation to, enter into understandings in writing (“Pricing Agreements”) whereby the Tendering Partner will agree in advance as to the acceptability of a Net Proceeds amount at or below the Base Amount.
Furthermore, the General Partner shall establish pricing notification procedures with each such Tendering Partner, such that the Tendering Partner will have the maximum opportunity practicable to determine whether to become a Withdrawing Partner
pursuant to Section 8.6.C(3)(c) below. 
  
 (c) The General
Partner, upon notification of the price per REIT Share in the Stock Offering Funding from the managing underwriter(s), in the case of a registered public offering, or lead placement agent(s), in the event of an unregistered offering, engaged by the
General Partner in order to sell the Offered Shares, shall immediately use its reasonable efforts to notify each Tendering Partner of the price per REIT Share in the Stock Offering Funding and resulting Net Proceeds. Each Tendering Partner shall
have one hour (as such time may be extended by the General Partner) to elect to withdraw its Redemption (a Tendering Partner making such an election being a “Withdrawing Partner”), and Common Units with a REIT Shares Amount equal to
such excluded Offered Shares shall be considered to be withdrawn from the related Redemption; provided, however, that if Tendering Partners withdraw in excess of 20% of the Offered Shares, all Offered Shares will, at the General
Partner’s option, be deemed to have been withdrawn by all Tendering Partners. If a Tendering Partner, within such time period, does not notify the General Partner of such Tendering Partner’s election not to become a Withdrawing Partner,
then such Tendering Partner shall, except as otherwise provided in a Pricing Agreement, be deemed not to have withdrawn from the Redemption, without liability to the General Partner. To the extent that the General Partner is unable to notify any
Tendering Partner, such unnotified Tendering Partner shall, except as

otherwise provided in any Pricing Agreement, be deemed not to have elected to become a Withdrawing Partner. Each Tendering Partner whose Redemption is being
funded through the Stock Offering Funding who does not become a Withdrawing Partner shall have the right, subject to the approval of the managing underwriter(s) or placement agent(s) and restrictions of any applicable securities laws, to submit for
Redemption additional Common Units in a number no greater than the number of Common Units withdrawn. If more than one Tendering Partner so elects to redeem additional Common Units, then such Common Units shall be redeemed on a pro rata basis, based
on the number of additional Common Units sought to be so redeemed. To the extent that the Net Proceeds would be below the Base Amount, and to the extent that other Partners have not elected to redeem additional Common Units, then the Withdrawing
Partners shall bear their pro rata shares of the expenses described in Section 8.6.C(2) (such shares calculated as if such Limited Partners had not been Withdrawing Partners) as reasonably determined by the General Partner. 
  
 (d) The General Partner shall take all reasonable action in order to
effectuate the sale of the Offered Shares including, but not limited to, the entering into of an underwriting or placement agreement in customary form with the managing underwriter(s) or placement agent(s) selected for such underwriting by the
General Partner. Notwithstanding any other provision of this Agreement, if the managing underwriter(s) or placement agent(s) advises the General Partner in writing that marketing factors require a limitation of the number of shares to be offered,
then the General Partner shall so advise all Tendering Partners and the number of Common Units to be sold to the General Partner pursuant to the Redemption shall be allocated among all Tendering Partners in proportion, as nearly as practicable, to
the respective number of Common Units as to which each Tendering Partner elected to effect a Redemption. No Offered Shares excluded from the underwriting by reason of the managing underwriter’s or placement agent’s marketing limitation
shall be included in such offering. 
  
 (e) The General Partner
may include securities for its own account in any offering made pursuant to Section 8.6.C.1 hereof and, if the managing underwriter or placement agent has not limited the number of Registrable Shares to be offered, the General Partner may
include securities for the account of others in such offering, in each case only if and to the extent that the managing underwriter or placement agent, the General Partner and Tendering Partners owning Common Units representing at least seventy-five
percent (75%) of the Common Units with respect to which the Stock Offering Funding is being effected so agree in writing. 
  
 D. Each Limited Partner covenants and agrees with the General Partner that all Tendered Units shall be delivered to the General Partner free and clear of
all liens, claims and encumbrances whatsoever and should any such liens, claims and/or encumbrances exist or arise with respect to such Tendered Units, the General Partner shall be under no obligation to acquire the same. Each Limited Partner
further agrees that, in the event any state or local property transfer tax is payable as a result of the transfer of its Tendered Units to the General Partner (or its designee), such Limited Partner shall assume and pay such transfer tax.

  
 E. Notwithstanding the provisions of Section 8.6.A,
8.6.B, 8.6.C or any other provision of this Agreement, a Limited Partner (i) shall not be entitled to effect a Redemption for cash pursuant to Section 8.6.A or an exchange for REIT Shares pursuant to Section 8.6.B to the

  

 58 

 
extent the ownership or right to acquire REIT Shares pursuant to such exchange by such Partner on the Specified Redemption Date could cause such Partner or
any other Person, or, in the opinion of counsel selected by the General Partner, may cause such Partner or any other Person, to violate the restrictions on ownership and transfer of REIT Shares set forth in the Charter and (ii) shall have no rights
under this Agreement to acquire REIT Shares which would otherwise be prohibited under the Charter. The limitation set forth in Section 8.6.E(i) above shall not limit the ability of a Limited Partner to require a Stock Offering Funding
pursuant to the terms of Section 8.6.C if (A) the Offering Units exceed (a) 9.8% of the REIT Shares, calculated in accordance with the methodology for calculating the percentage of ownership of a Person for purposes of the ownership limit
pursuant to Article VI of the Charter (subject to adjustment in connection with any Adjustment Event) and (b) $50,000,000 gross value based on a Common Unit price equal to the REIT Share Market Value, and (B) the General Partner is eligible to file
a registration statement under Form S-3 (or any successor form similar thereto). To the extent any attempted Redemption or exchange for REIT Shares would be in violation of this Section 8.6.E, it shall be null and void ab initio and
such Limited Partner shall not acquire any rights or economic interest in the cash otherwise payable upon such Redemption or the REIT Shares otherwise issuable upon such exchange. 
  
 F. Notwithstanding anything herein to the contrary (but subject to Section 8.6.E, with respect to any Redemption or
exchange for REIT Shares pursuant to this Section 8.6): 
  
 (1) All Common Units acquired by the General Partner pursuant thereto shall automatically, and without further action required, be converted into and deemed to be General Partner Interests comprised of the same number and class of Common
Units. 
  
 (2) Without the consent of the General Partner, each
Limited Partner may not effect a Redemption for less than 1,000 Common Units or, if the Limited Partner holds less than 1,000 Common Units, all of the Common Units held by such Limited Partner. 
  
 (3) Without the consent of the General Partner, each Limited Partner may not
effect a Redemption during the period after the Partnership Record Date with respect to a distribution and before the record date established by the General Partner for a distribution to its common stockholders of some or all of its portion of such
distribution. 
  
 (4) Notwithstanding anything herein to the
contrary, in the event the General Partner gives notice to all Limited Partners (a “Primary Offering Notice”) that it desires to effect a primary offering of its equity securities for cash (other than an offering in connection with
a merger, consolidation or similar transaction, or employee benefit or similar plans) then, unless the General Partner otherwise consents, the actions described in Section 8.6.C as to a Stock Offering Funding with respect to any Notice of
Redemption with respect to Excess Units thereafter received may be delayed until the earlier of (a) the completion of the primary offering or (b) 120 days following the giving of the Primary Offering Notice; provided that, to the
extent that the managing underwriter(s) of such primary offering advise that the inclusion of such additional REIT Shares will not adversely affect the offering, additional REIT Shares the proceeds of which are to be used to satisfy a Redemption
with respect to such Excess Units (a “Subsequent Redemption”) (without regard to the limitations of subparagraph (2) of this paragraph F) shall be included in such offering, and the procedures of this Section 8.6 shall

  

 59 

 
otherwise be followed as closely as practicable; provided, further that a Primary Offering Notice may be given no more than twice in any
Twelve-Month Period without the Consent of the Limited Partners. 
  
 (5) The General Partner may delay a Stock Offering Funding, such that it will not occur (1) during the same Twelve-Month Period as the General Partner has effected a “Demand Registration” pursuant to the Registration Rights
Agreements dated as of October 27, 2004, among the General Partner and certain Limited Partners (it being understood that in the event a Notice of Redemption is received prior to the receipt of requisite requests for a Demand Registration, such
Notice of Redemption shall control, and vice versa) or (b) within 120 days following the closing of any prior public offering of similar securities by the General Partner. 
  
 (6) The consummation of any Redemption or exchange for REIT Shares shall be subject to the expiration or termination of the
applicable waiting period, if any, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. 
  
 (7) Each Tendering Partner shall continue to own all Common Units subject to any Redemption or exchange for REIT Shares, and be treated as a Limited
Partner with respect to such Common Units for all purposes of this Agreement, until such Common Units are transferred to the General Partner and paid for or exchanged on the Specified Redemption Date. Until a Specified Redemption Date, and provided
the General Partner has issued REIT shares pursuant to Section 8.6.B, the Tendering Partner shall have no rights as a stockholder of the General Partner with respect to such Tendering Partner’s Common Units. 
  
 G. Notwithstanding the provisions of this Section 8.6 permitting the
General Partner to delay a Public Offering Funding by virtue of an event described in Section 8.6.C, the giving of a Primary Offering Notice, or a delay referred to in Section 8.6.F(5), the General Partner shall use its reasonable efforts to
take all such actions, as are consistent with the purposes of such delay provisions, to effect a Stock Offering Funding at the earliest time practicable. It is understood that such periods of delay shall run, to the extent practicable, concurrently,
and shall not limit the right of a Limited Partner to deliver a Notice of Redemption. 
  
 H. In the event that the Partnership issues additional Partnership Interests to any Additional Limited Partner pursuant to Section 4.3.B, the General Partner shall make such revisions to this Section 8.6
as it determines are necessary to reflect the issuance of such additional Partnership Interests. 
  
 Section 8.7 Conversion of Profits Interest Units. 
  
 A. A Profits Interest Unitholder shall have the right (the “Conversion Right”), at his or her option, at any time to convert all or a portion of his or her Vested Profits Interest Units into Common
Units; provided, however, that a holder may not exercise the Conversion Right for less than one thousand (1,000) Vested Profits Interest Units or, if such holder holds less than one thousand Vested Profits Interest Units, all of
the Vested Profits Interest Units held by such holder. Profits Interest Unitholders shall not have the right to convert Unvested Profits Interest Units into Common Units until they become Vested Profits Interest Units; provided,
however, that when a Profits Interest Unitholder is notified of the expected occurrence of an event that will 

  

 60 

 
cause his or her Unvested Profits Interest Units to become Vested Profits Interest Units, such Profits Interest Unitholder may give the Partnership a
Conversion Notice conditioned upon and effective as of the time of vesting and such Conversion Notice, unless subsequently revoked by the Profits Interest Unitholder, shall be accepted by the Partnership subject to such condition. In all cases, the
conversion of any Profits Interest Units into Common Units shall be subject to the conditions and procedures set forth in this Section 8.7. 
  
 B. A holder of Vested Profits Interest Units may convert such Units into an equal number of fully paid and non-assessable Common Units, giving effect to
all adjustments (if any) made pursuant to Section 4.5. Notwithstanding the foregoing, in no event may a holder of Vested Profits Interest Units convert a number of Vested Profits Interest Units that exceeds (x) the Economic Capital Account
Balance of such Limited Partner, to the extent attributable to his or her ownership of Profits Interest Units, divided by (y) the Common Unit Economic Balance, in each case as determined as of the effective date of conversion (the “Capital
Account Limitation”). In order to exercise his or her Conversion Right, a Profits Interest Unitholder shall deliver a notice (a “Conversion Notice”) in the form attached as Exhibit G to the Partnership (with a copy
to the General Partner) not less than 10 nor more than 60 days prior to a date (the “Conversion Date”) specified in such Conversion Notice; provided, however, that if the General Partner has not given to the Profits
Interest Unitholders notice of a proposed or upcoming Transaction (as defined below) at least thirty (30) days prior to the effective date of such Transaction, then Profits Interest Unitholders shall have the right to deliver a Conversion Notice
until the earlier of (x) the tenth (10th) day after such notice from the General Partner of a Transaction or (y) the third business day immediately preceding the effective date of such Transaction. A Conversion Notice shall be provided in the manner
provided in Section 15.1. Each Profits Interest Unitholder covenants and agrees with the Partnership that all Vested Profits Interest Units to be converted pursuant to this Section 8.7.A shall be free and clear of all liens.
Notwithstanding anything herein to the contrary, a holder of Profits Interest Units may deliver a Redemption Notice pursuant to Section 8.6.A relating to those Common Units that will be issued to such holder upon conversion of such Profits
Interest Units into Common Units in advance of the Conversion Date; provided, however, that the redemption of such Common Units by the Partnership shall in no event take place until on or after the Conversion Date. For clarity, it is
noted that the objective of this paragraph is to put a Profits Interest Unitholder in a position where, if he or she so wishes, the Common Units into which his or her Vested Profits Interest Units will be converted can be redeemed by the Partnership
pursuant to Section 8.6.A simultaneously with such conversion, with the further consequence that, if the Company elects to assume the Partnership’s redemption obligation with respect to such Common Units under Section 8.6.B by
delivering to such holder REIT Shares rather than cash, then such holder can have such REIT Shares issued to him or her simultaneously with the conversion of his or her Vested Profits Interest Units into Common Units. The General Partner shall
cooperate with a Profits Interest Unitholder to coordinate the timing of the different events described in the foregoing sentence. 
  
 C. The Partnership, at any time at the election of the General Partner, may cause any number of Vested Profits Interest Units held by a Profits Interest
Unitholder to be converted (a “Forced Conversion”) into an equal number of Common Units, giving effect to all adjustments (if any) made pursuant to Section 4.5; provided, however, that the Partnership may not
cause a Forced Conversion of any Profits Interest Units that would not at the time be eligible for 

  

 61 

 
conversion at the option of such Profits Interest Unitholder pursuant to Section 8.7.B. In order to exercise its right of Forced Conversion, the
Partnership shall deliver a notice (a “Forced Conversion Notice”) in the form attached as Exhibit H to the applicable Profits Interest Unitholder not less than 10 nor more than 60 days prior to the Conversion Date specified
in such Forced Conversion Notice. A Forced Conversion Notice shall be provided in the manner provided in Section 15.1. 
  
 D. A conversion of Vested Profits Interest Units for which the holder thereof has given a Conversion Notice or the Partnership has given a Forced
Conversion Notice shall occur automatically after the close of business on the applicable Conversion Date without any action on the part of such Profits Interest Unitholder, as of which time such Profits Interest Unitholder shall be credited on the
books and records of the Partnership with the issuance as of the opening of business on the next day of the number of Common Units issuable upon such conversion. After the conversion of Profits Interest Units as aforesaid, the Partnership shall
deliver to such Profits Interest Unitholder, upon his or her written request, a certificate of the General Partner certifying the number of Common Units and remaining Profits Interest Units, if any, held by such person immediately after such
conversion. The Assignee of any Limited Partner pursuant to Article 11 hereof may exercise the rights of such Limited Partner pursuant to this Section 8.7 and such Limited Partner shall be bound by the exercise of such rights by the
Assignee. 
  
 E. For purposes of making future allocations under
Section 6.2.C and applying the Capital Account Limitation, the portion of the Economic Capital Account Balance of the applicable Profits Interest Unitholder that is treated as attributable to his or her Profits Interest Units shall be
reduced, as of the date of conversion, by the product of the number of Profits Interest Units converted and the Common Unit Economic Balance. 
  
 F. If the Partnership or the General Partner shall be a party to any transaction (including without limitation a merger, consolidation, unit exchange,
self tender offer for all or substantially all Common Units or other business combination or reorganization, or sale of all or substantially all of the Partnership’s assets, but excluding any transaction which constitutes an Adjustment Event)
in each case as a result of which Common Units shall be exchanged for or converted into the right, or the Holders shall otherwise be entitled, to receive cash, securities or other property or any combination thereof (each of the foregoing being
referred to herein as a “Transaction”), then the General Partner shall, immediately prior to the Transaction, exercise its right to cause a Forced Conversion with respect to the maximum number of Profits Interest Units then eligible
for conversion, taking into account any allocations that occur in connection with the Transaction or that would occur in connection with the Transaction if the assets of the Partnership were sold at the Transaction price or, if applicable, at a
value determined by the General Partner in good faith using the value attributed to the Common Units in the context of the Transaction (in which case the Conversion Date shall be the effective date of the Transaction). In anticipation of such Forced
Conversion and the consummation of the Transaction, the Partnership shall use commercially reasonable efforts to cause each Profits Interest Unitholder to be afforded the right to receive in connection with such Transaction in consideration for the
Common Units into which his or her Profits Interest Units will be converted the same kind and amount of cash, securities and other property (or any combination thereof) receivable upon the consummation of such Transaction by a Holder of the same
number of Common Units, assuming such Holder is not a Person with which the Partnership consolidated 

  

 62 

 
or into which the Partnership merged or which merged into the Partnership or to which such sale or transfer was made, as the case may be (a
“Constituent Person”), or an affiliate of a Constituent Person. In the event that Holders have the opportunity to elect the form or type of consideration to be received upon consummation of the Transaction, prior to such Transaction
the General Partner shall give prompt written notice to each Profits Interest Unitholder of such election, and shall use commercially reasonable efforts to afford the Profits Interest Unitholders the right to elect, by written notice to the General
Partner, the form or type of consideration to be received upon conversion of each Profits Interest Unit held by such holder into Common Units in connection with such Transaction. If a Profits Interest Unitholder fails to make such an election, such
holder (and any of its transferees) shall receive upon conversion of each Profits Interest Unit held by him or her (or by any of his or her transferees) the same kind and amount of consideration that a Holder would receive if such Holder failed to
make such an election. Subject to the rights of the Partnership and the Company under any Vesting Agreement and the relevant terms of any applicable Stock Plan, the Partnership shall use commercially reasonable effort to cause the terms of any
Transaction to be consistent with the provisions of this Section 8.7.F and to enter into an agreement with the successor or purchasing entity, as the case may be, for the benefit of any Profits Interest Unitholders whose Profits Interest
Units will not be converted into Common Units in connection with the Transaction that will (i) contain provisions enabling the holders of Profits Interest Units that remain outstanding after such Transaction to convert their Profits Interest Units
into securities as comparable as reasonably possible under the circumstances to the Common Units and (ii) preserve as far as reasonably possible under the circumstances the distribution, special allocation, conversion, and other rights set forth in
the Agreement for the benefit of the Profits Interest Unitholders. 
  
 Section 8.8
Voting Rights of Profits Interest Units 
  
 Profits
Interest Unitholders shall (a) have those voting rights required from time to time by applicable law, if any, (b) have the same voting rights as a Holder, with the Profits Interest Units voting as a single class with the Common Units and having one
vote per Profits Interest Unit; and (c) have the additional voting rights that are expressly set forth below. So long as any Profits Interest Units remain outstanding, the Partnership shall not, without the affirmative vote of the holders of at
least a majority of the Profits Interest Units outstanding at the time, given in person or by proxy, either in writing or at a meeting (voting separately as a class), amend, alter or repeal, whether by merger, consolidation or otherwise, the
provisions of the Agreement applicable to Profits Interest Units so as to materially and adversely affect any right, privilege or voting power of the Profits Interest Units or the Profits Interest Unitholders as such, unless such amendment,
alteration, or repeal affects equally, ratably and proportionately the rights, privileges and voting powers of the holders of Common Units; but subject, in any event, to the following provisions: (i) with respect to any Transaction, so long as the
Profits Interest Units are treated in accordance with Section 8.7.F hereof, the consummation of such Transaction shall not be deemed to materially and adversely affect such rights, preferences, privileges or voting powers of the Profits
Interest Units or the Profits Interest Unitholders as such; and (ii) any creation or issuance of any Partnership Units or of any class or series of Partnership Interest including without limitation additional Partnership Units or Profits Interest
Units, whether ranking senior to, junior to, or on a parity with the Profits Interest Units with respect to distributions and the distribution of assets upon liquidation, dissolution or winding up, shall not be deemed to materially and adversely
affect such rights, preferences, privileges or voting 

  

 63 

 
powers of the Profits Interest Units or the Profits Interest Unitholders as such. The foregoing voting provisions will not apply if, at or prior to the time
when the act with respect to which such vote would otherwise be required will be effected, all outstanding Profits Interest Units shall have been converted into Common Units. 
  
 ARTICLE 9. 
 BOOKS, RECORDS, ACCOUNTING AND REPORTS 
  
 Section 9.1 Records and
Accounting 
  
 The General Partner shall keep or cause to be
kept at the principal office of the Partnership appropriate books and records with respect to the Partnership’s business, including without limitation, all books and records necessary to provide to the Limited Partners any information, lists
and copies of documents required to be provided pursuant to Section 9.3. Any records maintained by or on behalf of the Partnership in the regular course of its business may be kept on, or be in the form of any information storage device,
provided, that the records so maintained are convertible into clearly legible written form within a reasonable period of time. The books of the Partnership shall be maintained, for financial and tax reporting purposes, on an accrual
basis in accordance with generally accepted accounting principles. 
  
 Section 9.2
Fiscal Year 
  
 The fiscal year of the Partnership shall
be the calendar year. 
  
 Section 9.3 Reports 
  
 A. As soon as practicable, but in no event later than 105 days after the
close of each Partnership Year, or such earlier date as they are filed with the Securities and Exchange Commission, the General Partner shall cause to be mailed to each Limited Partner as of the close of the Partnership Year, an annual report
containing financial statements of the Partnership, or of the General Partner if such statements are prepared solely on a consolidated basis with the General Partner, for such Partnership Year, presented in accordance with generally accepted
accounting principles, such statements to be audited by a nationally recognized firm of independent public accountants selected by the General Partner. 
  
 B. As soon as practicable, but in no event later than 45 days after the close of each calendar quarter (except the last calendar quarter of each year), or
such earlier date as they are filed with the Securities and Exchange Commission, the General Partner shall cause to be mailed to each Limited Partner as of the last day of the calendar quarter, a report containing unaudited financial statements of
the Partnership, or of the General Partner, if such statements are prepared solely on a consolidated basis with the applicable law or regulation, or as the General Partner determines to be appropriate. 
  
 Section 9.4 Nondisclosure of Certain Information 
  
 Notwithstanding the provisions of Sections 9.1 and 9.3, the
General Partner may keep confidential from the Limited Partners any information that the General Partner believes to be in the nature of trade secrets or other information the disclosure of which the General Partner in good faith believes is not in
the best interest of the Partnership or which the Partnership is required by law or by agreements with unaffiliated third parties to keep confidential. 
  

 64 

 ARTICLE 10. 
 TAX MATTERS 
  
 Section 10.1 Preparation of Tax
Returns 
  
 The General Partner shall arrange for the
preparation and timely filing of all returns of Partnership income, gains, deductions, losses and other items required of the Partnership for federal and state income tax purposes and shall use all reasonable efforts to furnish, within 120 days of
the close of each taxable year, the tax information reasonably required by Limited Partners for federal and state income tax reporting purposes. Each Limited Partner shall promptly provide the General Partner with any information reasonably
requested by the General Partner relating to any Contributed Property contributed (directly or indirectly) by such Limited Partner to the Partnership. 
  
 Section 10.2 Tax Elections 
  
 Except as otherwise provided herein, the General Partner shall, in its sole and absolute discretion, determine whether to make any available election
pursuant to the Code, including the election under Section 754 of the Code. The General Partner shall have the right to seek to revoke any such election (including without limitation, any election under Section 754 of the Code) upon the General
Partner’s determination in its sole and absolute discretion that such revocation is the best interests of the Partners. 
  
 Section 10.3 Tax Matters Partner 
  
 A. The General Partner shall be the “tax matters partner” of the Partnership for federal income tax purposes. Pursuant to Section 6230(e)
of the Code, upon receipt of notice from the IRS of the beginning of an administrative proceeding with respect to the Partnership, the tax matters partner shall furnish the IRS with the name, address and profit interest of each of the Limited
Partners and Assignees; provided, however, that such information is provided to the Partnership by the Limited Partners and Assignees. 
  
 B. The tax matters partner is authorized, but not required: 
  
 (1) to enter into any settlement with the IRS with respect to any administrative or judicial proceedings for the adjustment of Partnership items required
to be taken into account by a Partner for income tax purposes (such administrative proceedings being referred to as a “tax audit” and such judicial proceedings being referred to as “judicial review”), and in the
settlement agreement the tax matters partner may expressly state that such agreement shall bind all Partners, except that such settlement agreement shall not bind any Partner (i) who (within the time prescribed pursuant to the Code and Regulations)
files a statement with the IRS providing that the tax matters partner shall not have the authority to enter into a settlement agreement on behalf of such Partner or (ii) who is a “notice partner” (as defined in Section 6231 of the
Code) or a member of a “notice group” (as defined in Section 6223(b)(2) of the Code); 
  

 65 

 (2) in the event that a notice of a final administrative adjustment at the Partnership level of any item
required to be taken into account by a Partner for tax purposes (a “final adjustment”) is mailed to the tax matters partner, to seek judicial review of such final adjustment, including the filing of a petition for readjustment with
the Tax Court or the United States Claims Court, or the filing of a complaint for refund with the District Court of the United States for the district in which the Partnership’s principal place of business is located; 
  
 (3) to intervene in any action brought by any other Partner for judicial
review of a final adjustment; 
  
 (4) to file a request for an
administrative adjustment with the IRS at any time and, if any part of such request is not allowed by the IRS, to file an appropriate pleading (petition or complaint) for judicial review with respect to such request; 
  
 (5) to enter into an agreement with the IRS to extend the period for
assessing any tax which is attributable to any item required to be taken into account by a Partner for tax purposes, or an item affected by such item; and 
  
 (6) to take any other action on behalf of the Partners of the Partnership in connection with any tax audit or judicial review proceeding to the extent
permitted by applicable law or regulations. 
  
 The taking of any
action and the incurring of any expense by the tax matters partner in connection with any such proceeding, except to the extent required by law, is a matter in the sole and absolute discretion of the tax matters partner and the provisions relating
to indemnification of the General Partner set forth in Section 7.7 shall be fully applicable to the tax matters partner in its capacity as such. 
  
 C. The tax matters partner shall receive no compensation for its services. All third party costs and expenses incurred by the tax matters partner in
performing its duties as such (including legal and accounting fees) shall be borne by the Partnership. Nothing herein shall be construed to restrict the Partnership from engaging an accounting firm or law firm to assist the tax matters partner in
discharging its duties hereunder, so long as the compensation paid by the Partnership for such services is reasonable. 
  
 Section 10.4 Organizational Expenses 
  
 The Partnership shall elect to deduct expenses, if any, incurred by it in organizing the Partnership ratably over a 60-month period as provided in Section
709 of the Code. 
  
 Section 10.5 Withholding 
  
 Each Limited Partner hereby authorizes the Partnership to withhold from or
pay on behalf of or with respect to such Limited Partner any amount of federal, state, local, or foreign taxes that the General Partner determines that the Partnership is required to withhold or pay with respect to any amount distributable or
allocable to such Limited Partner pursuant to this Agreement, including, without limitation, any taxes required to be withheld or paid by the Partnership pursuant to Sections 1441, 1442, 1445 or 1446 of the Code. Any amount paid on 

  

 66 

 
behalf of or with respect to a Limited Partner shall constitute a receivable of the Partnership from such Limited Partner, which receivable shall be paid by
such Limited Partner within 15 days after notice from the General Partner that such payment must be made unless (i) the Partnership withholds such payment from a distribution which would otherwise be made to the Limited Partner or (ii) the General
Partner determines, in its sole and absolute discretion, that such payment may be satisfied out of the available funds of the Partnership which would, but for such payment, be distributed to the Limited Partner. Any amounts withheld pursuant to the
foregoing clauses (i) or (ii) shall be treated as having been distributed to such Limited Partner. Each Limited Partner hereby unconditionally and irrevocably grants to the Partnership a security interest in such Limited Partner’s Partnership
Interest to secure such Limited Partner’s obligation to pay to the Partnership any amounts required to be paid pursuant to this Section 10.5. Any amounts payable by a Limited Partner hereunder shall bear interest at the base rate on
corporate loans at large United States money center commercial banks, as published from time to time in the Wall Street Journal, plus two percentage points (but not higher than the maximum lawful rate) from the date such amount is due
(i.e., 15 days after demand) until such amount is paid in full. Each Limited Partner shall take such actions as the Partnership or the General Partner shall request in order to perfect or enforce the security interest created hereunder.

  
 ARTICLE 11. 
 TRANSFERS AND WITHDRAWALS 
  
 Section 11.1 Transfer 
  
 A. The term “transfer,” when used in this Article 11 with respect to a Partnership Interest, shall be deemed to refer to a
transaction by which the General Partner purports to assign its General Partner Interest to another Person or by which a Limited Partner purports to assign its Limited Partner Interest to another Person, and includes a sale, assignment, gift
(outright or in trust), pledge, encumbrance, hypothecation, mortgage, exchange or any other disposition by law or otherwise. The term “transfer” when used in this Article 11 does not include any Redemption or exchange for REIT
Shares pursuant to Section 8.6 except as otherwise provided herein. No part of the interest of a Limited Partner shall be subject to the claims of any creditor, any spouse for alimony or support, or to legal process, and may not be
voluntarily or involuntarily alienated or encumbered except as may be specifically provided for in this Agreement or consented to by the General Partner. 
  
 B. No Partnership Interest shall be transferred, in whole or in part, except in accordance with the terms and conditions set forth in this Article
11. Any transfer or purported transfer of a Partnership Interest not made in accordance with this Article 11 shall be null and void ab initio unless otherwise consented to by the General Partner in its sole and absolute discretion.

  
 Section 11.2 Transfer of General Partner’s Partnership Interest

  
 A. Except in connection with a Termination Transaction
permitted under Section 11.2.B, the General Partner shall not withdraw from the Partnership and shall not transfer all or any portion of its interest in the Partnership (whether by sale, statutory merger or consolidation, liquidation or
otherwise), other than to an Affiliate, without the Consent of the Limited Partners, 

  

 67 

 
which may be given or withheld by each Limited Partner in its sole and absolute discretion, and only upon the admission of a successor General Partner
pursuant to Section 12.1. Upon any transfer of a Partnership Interest in accordance with the provisions of this Section 11.2, the transferee shall become a substitute General Partner for all purposes herein, and shall be vested with
the powers and rights of the transferor General Partner, and shall be liable for all obligations and responsible for all duties of the General Partner, once such transferee has executed such instruments as may be necessary to effectuate such
admission and to confirm the agreement of such transferee to be bound by all the terms and provisions of this Agreement with respect to the Partnership Interest so acquired. It is a condition to any transfer otherwise permitted hereunder that the
transferee assumes, by operation of law or express agreement, all of the obligations of the transferor General Partner under this Agreement with respect to such transferred Partnership Interest, and no such transfer (other than pursuant to a
statutory merger or consolidation wherein all obligations and liabilities of the transferor General Partner are assumed by a successor corporation by operation of law) shall relieve the transferor General Partner of its obligations under this
Agreement without the Consent of the Limited Partners, in their reasonable discretion. In the event the General Partner withdraws from the Partnership, in violation of this Agreement or otherwise, or otherwise dissolves or terminates, or upon the
Incapacity of the General Partner, all of the remaining Partners may elect to continue the Partnership business by selecting a substitute General Partner in accordance with the Act. 
  
 B. The General Partner shall not engage in any merger, consolidation or other combination with or into another person, sale
of all or substantially all of its assets or any reclassification, recapitalization or change of its outstanding equity interests (“Termination Transaction”) unless (1) the Termination Transaction has been approved by a Consent of
the Partners and (2) either clause (a) or (b) below is satisfied: 
  
 (a) in connection with such Termination Transaction all Limited Partners either will receive, or will have the right to elect to receive, for each Common Unit an amount of cash, securities, or other property equal to the product of the REIT
Shares Amount and the greatest amount of cash, securities or other property paid to a holder of one REIT Share in consideration of one REIT Share in connection with the Termination Transaction; provided, that, if, in connection with
the Termination Transaction, a purchase, tender or exchange offer shall have been made to and accepted by the holders of more than fifty percent (50%) of the outstanding REIT Shares, each Holder of Common Units shall receive, or shall have the right
to elect to receive, the greatest amount of cash, securities, or other property which such holder would have received had it exercised its right to Redemption (as set forth in Section 8.6) and received REIT Shares in exchange for its Common
Units immediately prior to the expiration of such purchase, tender or exchange offer and had thereupon accepted such purchase, tender or exchange offer and then such Termination Transaction shall have been consummated; or 
  
 (b) the following conditions are met: (i) substantially all of the assets
directly or indirectly owned by the surviving entity are held directly or indirectly by the Partnership or another limited partnership or limited liability company which is the survivor of a merger, consolidation or combination of assets with the
Partnership (in each case, the “Surviving Partnership”); (ii) the holders of Common-Equivalent Units own a percentage interest of the Surviving Partnership based on the relative fair market value of the net assets of the Partnership
and the other net assets of the Surviving Partnership immediately prior to the 

  

 68 

 
consummation of such transaction; (iii) the rights, preferences and privileges of such holders in the Surviving Partnership are at least as favorable as
those in effect immediately prior to the consummation of such transaction and as those applicable to any other limited partners or non-managing members of the Surviving Partnership; and (iv) such rights of the Limited Partners include at least one
of the following: (a) the right to redeem their interests in the Surviving Partnership for the consideration available to such persons pursuant to Section 11.2.B(a); or (b) the right to redeem their Common Units for cash on terms equivalent
to those in effect with respect to their Common Units immediately prior to the consummation of such transaction, or, if the ultimate controlling person of the Surviving Partnership has publicly traded common equity securities, such common equity
securities, with an exchange ratio based on the determination of relative fair market value of such securities and the REIT Shares. 
  
 Section 11.3 Limited Partners’ Rights to Transfer 
  
 A. Prior to the twelve (12) month anniversary of the Effective Date, no Limited Partner shall transfer all or any portion of its Partnership Interest to
any transferee without the consent of the General Partner, which consent may be withheld in its sole and absolute discretion, or exercise its right of Redemption set forth in Section 8.6; provided, however, that any Limited
Partner may, at any time (whether prior to or after such twelve (12) month anniversary), without the consent of the General Partner, other than by way of exercise of the right of Redemption set forth in Section 8.6, (i) transfer all or any
portion of its Partnership Interest to the General Partner, (ii) transfer all or any portion of its Partnership Interest to an Immediate Family Member, subject to the provisions of Section 11.6, (iii) transfer all or any portion of its
Partnership Interest to a trust for the benefit of a charitable beneficiary or to a charitable foundation, subject to the provisions of Section 11.6, and (iv) subject to the provisions of Section 11.6, pledge (a
“Pledge”) all or any portion of its Partnership Interest to a lending institution, which is not an Affiliate of such Limited Partner, as collateral or security for a bona fide loan or other extension of credit with a scheduled
maturity date not sooner than the twelve (12) month anniversary of the Effective Date, and transfer such pledged Partnership Interest to such lending institution in connection with the exercise of remedies under such loan or extension or credit, and
the transfer of such pledged Partnership Interest by the lender to any transferee. After such twelve (12) month anniversary, each Limited Partner or Assignee (resulting from a transfer made pursuant to clauses (i)-(iv) of the proviso of the
preceding sentence) shall have the right to transfer all or any portion of its Partnership Interest, subject to the provisions of Section 11.6 and the satisfaction of each of the following conditions (in addition to the right of each such
Limited Partner or Assignee (A) to continue to make any such transfer permitted by clauses (i)-(iv) of such proviso or (B) to make any transfer to its Affiliates or members, in each case, without satisfying condition (1) below): 
  
 (1) General Partner Right of First Refusal. The transferring Partner
shall give written notice of the proposed transfer to the General Partner, which notice shall state (i) the identity of the proposed transferee, and (ii) the amount and type of consideration proposed to be received for the transferred Partnership
Units. The General Partner shall have ten (10) days upon which to give the transferring Partner notice of its election to acquire the Partnership Units on the proposed terms. If it so elects, it shall purchase the Partnership Units on such terms
within ten (10) days after giving notice of such election. If it does not so elect, the transferring Partner may transfer such Partnership Units to a third party, on economic terms no more favorable to the transferee than the proposed terms, subject
to the other conditions of this Section 11.3. 
  

 69 

 (2) Qualified Transferee. Any transfer of a Partnership Interest shall be made only to Qualified
Transferees. 
  
 It is a condition to any transfer otherwise
permitted hereunder that the transferee assumes by operation of law or express agreement all of the obligations of the transferor Limited Partner under this Agreement with respect to such transferred Partnership Interest and no such transfer (other
than pursuant to a statutory merger or consolidation wherein all obligations and liabilities of the transferor Partner are assumed by a successor corporation by operation of law) shall relieve the transferor Partner of its obligations under this
Agreement without the approval of the General Partner, in its reasonable discretion. Notwithstanding the foregoing, any transferee of any transferred Partnership Interest shall be subject to any and all ownership limitations contained in the
Charter, which may limit or restrict such transferee’s ability to exercise its Redemption rights, and to the representations in Section 3.4. Any transferee, whether or not admitted as a Substituted Limited Partner, shall take subject to
the obligations of the transferor hereunder. Unless admitted as a Substituted Limited Partner in accordance with Section 11.4.B, no transferee, whether by a voluntary transfer, by operation of law or otherwise, shall have any rights
hereunder, other than the rights of an Assignee as provided in and in compliance with Section 11.5. 
  
 B. If a Limited Partner is subject to Incapacity, the executor, administrator, trustee, committee, guardian, conservator, or receiver of such Limited
Partner’s estate shall have all the rights of a Limited Partner, but not more rights than those enjoyed by other Limited Partners, for the purpose of settling or managing the estate, and such power as the Incapacitated Limited Partner possessed
to transfer all or any part of his or its interest in the Partnership. The Incapacity of a Limited Partner, in and of itself, shall not dissolve or terminate the Partnership. 
  
 C. The General Partner may prohibit any transfer otherwise permitted under Section 11.3 by a Limited Partner of his
or her Partnership Units if, in the opinion of legal counsel to the Partnership, such transfer would require the filing of a registration statement under the Securities Act by the Partnership or would otherwise violate any federal or state
securities laws or regulations applicable to the Partnership or the Partnership Units. 
  
 Section 11.4 Substituted Limited Partners 
  
 A.
No Limited Partner shall have the right to substitute a transferee as a Limited Partner in his or her place (including any transferee permitted by Section 11.3). The General Partner shall, however, have the right to consent to the admission
of a transferee of the interest of a Limited Partner pursuant to this Section 11.4 as a Substituted Limited Partner, which consent may be given or withheld by the General Partner in its sole and absolute discretion. The General Partner’s
failure or refusal to permit a transferee of any such interests to become a Substituted Limited Partner shall not give rise to any cause of action against the Partnership or any Partner. 
  
 B. A transferee who has been admitted as a Substituted Limited Partner in accordance with this Article 11 shall have
all the rights and powers and be subject to all the 

  

 70 

 
restrictions and liabilities of a Limited Partner under this Agreement. The admission of any transferee as a Substituted Limited Partner shall be subject to
the transferee executing and delivering to the Partnership an acceptance of all of the terms and conditions of this Agreement (including without limitation, the provisions of Section 2.4 and such other documents or instruments as may be
required to effect the admission), each in form and substance satisfactory to the General Partner) and the acknowledgment by such transferee that each of the representations and warranties set forth in Section 3.4 are true and correct with
respect to such transferee as of the date of the transfer of the Partnership Interest to such transferee and will continue to be true to the extent required by such representations and warranties. 
  
 C. Upon the admission of a Substituted Limited Partner, the General Partner
shall amend Exhibit A to reflect the name, address, number of Partnership Units, and Percentage Interest of such Substituted Limited Partner and to eliminate or adjust, if necessary, the name, address and interest of the predecessor of such
Substituted Limited Partner. 
  
 Section 11.5 Assignees 
  
 If the General Partner, in its sole and absolute discretion, does not
consent to the admission of any permitted transferee under Section 11.3 as a Substituted Limited Partner, as described in Section 11.4, such transferee shall be considered an Assignee for purposes of this Agreement. An Assignee shall
be entitled to all the rights of an assignee of a limited partnership interest under the Act, including the right to receive distributions from the Partnership and the share of Net Income, Net Losses, gain and loss attributable to the Partnership
Units assigned to such transferee, the rights to transfer the Partnership Units provided in this Article 11 and the right of Redemption provided in Section 8.6, but shall not be deemed to be a Holder of Partnership Units for any other
purpose under this Agreement, and shall not be entitled to effect a Consent with respect to such Partnership Units on any matter presented to the Limited Partners for approval (such Consent remaining with the transferor Limited Partner). In the
event any such transferee desires to make a further assignment of any such Partnership Units, such transferee shall be subject to all the provisions of this Article 11 to the same extent and in the same manner as any Limited Partner desiring
to make an assignment of Partnership Units. Notwithstanding anything contained in this Agreement to the contrary, as a condition to becoming an Assignee, any prospective Assignee must first execute and deliver to the Partnership an acknowledgment
that each of the representations and warranties set forth in Section 3.4 are true and correct with respect to such prospective Assignee as of the date of the prospective assignment of the Partnership Interest to such prospective Assignee and
will continue to be true to the extent required by such representations or warranties. 
  
 Section 11.6 General Provisions 
  
 A. No Limited
Partner may withdraw from the Partnership other than as a result of (i) a permitted transfer of all of such Limited Partner’s Partnership Units in accordance with this Article 11 and the transferee(s) of such Partnership Units being
admitted to the Partnership as a Substituted Limited Partner or (ii) pursuant to the exercise of its right of Redemption of all of such Limited Partner’s Partnership Units under Section 8.6; provided that after such
transfer, exchange or redemption such Limited Partner owns no Partnership Interest. 
  

 71 

 B. Any Limited Partner who shall transfer all of such Limited Partner’s Partnership Units in a
transfer permitted pursuant to this Article 11 where such transferee was admitted as a Substituted Limited Partner or pursuant to the exercise of its rights of Redemption of all of such Limited Partner’s Partnership Units under
Section 8.6 shall cease to be a Limited Partner; provided that after such transfer, exchange or redemption such Limited Partner owns no Partnership Interest. 
  
 C. Transfers pursuant to this Article 11 may only be made on the first day of a fiscal quarter of the Partnership,
unless the General Partner otherwise agrees. 
  
 D. If any
Partnership Interest is transferred, assigned or redeemed during any quarterly segment of the Partnership’s Partnership Year in compliance with the provisions of this Article 11 or transferred or redeemed pursuant to Sections 8.6,
16.4 or 17.4 on any day other than the first day of a Partnership Year, then Net Income, Net Losses, each item thereof and all other items attributable to such Partnership Interest for such Partnership Year shall be divided and
allocated between the transferor Partner and the transferee Partner by taking into account their varying interests during the Partnership Year using a method selected by the General Partner that is in accordance with the Code. Except as otherwise
agreed by the General Partner, all distributions of Available Cash with respect to which the Partnership Record Date is before the date of such transfer, assignment, exchange or redemption shall be made to the transferor Partner, and all
distributions of Available Cash thereafter, in the case of a transfer or assignment other than a redemption, shall be made to the transferee Partner. 
  
 E. In addition to any other restrictions on transfer herein contained, including without limitation the provisions of this Article 11 and
Section 2.6, in no event may any transfer or assignment of a Partnership Interest by any Partner (including pursuant to a Redemption or exchange for REIT Shares by the Partnership or the General Partner) be made (i) to any person or entity
who lacks the legal right, power or capacity to own a Partnership Interest; (ii) in violation of applicable law; (iii) except with the consent of the General Partner, which may be given or withheld in its sole and absolute discretion, of any
component portion of a Partnership Interest, such as the Capital Account, or rights to distributions, separate and apart from all other components of a Partnership Interest; (iv) except with the consent of the General Partner, which may be given or
withheld in its sole and absolute discretion, if in the opinion of legal counsel to the Partnership such transfer could cause a termination of the Partnership for federal or state income tax purposes (except as a result of the Redemption or exchange
for REIT Shares of all Common Units held by all Limited Partners or pursuant to a transaction expressly permitted under Section 11.2); (v) if in the opinion of counsel to the Partnership such transfer could cause the Partnership to cease to
be classified as a partnership for federal income tax purposes (except as a result of the Redemption or exchange for REIT Shares of all Common Units held by all Limited Partners); (vi) if such transfer could, in the opinion of counsel to the
Partnership, cause the Partnership to become, with respect to any employee benefit plan subject to Title I of ERISA, a “party-in-interest” (as defined in Section 3(14) of ERISA) or a “disqualified person” (as defined in Section
4975(e) of the Code); (vii) if such transfer could, in the opinion of counsel to the Partnership, cause any portion of the assets of the Partnership to constitute assets of any employee benefit plan pursuant to Department of Labor Regulations
Section 2510.2-101; (viii) if such transfer requires the registration of such Partnership Interest pursuant to any applicable federal or state securities laws; (ix) except with the consent of the General Partner, which may be 

  

 72 

 
given or withheld in its sole and absolute discretion, if such transfer (1) could be treated as effectuated through an “established securities
market” or a “secondary market” (or the substantial equivalent thereof) within the meaning of Section 7704 of the Code, (2) could cause the Partnership to become a “Publicly Traded Partnership,” as such term is defined in
Sections 469(k)(2) or 7704(b) of the Code, (3) could be in violation of Section 3.4.E(5), or (4) could cause the Partnership to fail one or more of the Safe Harbors (as defined below); (x) if such transfer subjects the Partnership to be
regulated under the Investment Company Act of 1940, the Investment Advisors Act of 1940 or the Employee Retirement Income Security Act of 1974, each as amended; (xi) except with the consent of the General Partner, which may be given or withheld in
its sole discretion, if the transferee or assignee of such Partnership Interest is unable to make the representations set forth in Section 3.4.C; (xii) if such transfer is made to a lender to the Partnership or any Person who is related
(within the meaning of Section 1.752-4(b) of the Regulations) to any lender to the Partnership whose loan constitutes a Nonrecourse Liability, except with the consent of the General Partner, which may be given or withheld in its sole and absolute
discretion; and provided, that, as a condition to granting such consent the lender may be required to enter into an arrangement with the Partnership and the General Partner to redeem or exchange for the REIT Shares Amount any
Partnership Units in which a security interest is held simultaneously with the time at which such lender would be deemed to be a partner in the Partnership for purposes of allocating liabilities to such lender under Section 752 of the Code; or
(xiii) if in the opinion of legal counsel for the Partnership such transfer could adversely affect the ability of the General Partner to continue to qualify as a REIT or, except with the consent of the General Partner, which may be given or withheld
in its sole and absolute discretion, subject the General Partner to any additional taxes under Section 857 or Section 4981 of the Code. 
  
 F. The General Partner shall monitor the transfers of interests in the Partnership (including any acquisition of Common Units by the Partnership or the
General Partner) to determine (i) if such interests could be treated as being traded on an “established securities market” or a “secondary market (or the substantial equivalent thereof)” within the meaning of Section 7704 of the
Code and (ii) whether such transfers of interests could result in the Partnership being unable to qualify for the “safe harbors” set forth in Regulations Section 1.7704-1 (or such other guidance subsequently published by the IRS setting
forth safe harbors under which interests will not be treated as “readily tradable on a secondary market (or the substantial equivalent thereof)” within the meaning of Section 7704 of the Code) (the “Safe Harbors”). The
General Partner shall have the authority (but shall not be required) to take any steps it determines are necessary or appropriate in its sole and absolute discretion to prevent any trading of interests which could cause the Partnership to become a
“publicly traded partnership,” within the meaning of Code Section 7704, or any recognition by the Partnership of such transfers, or to insure that one or more of the Safe Harbors is met. 
  
 ARTICLE 12. 
 ADMISSION OF PARTNERS 
  
 Section 12.1 Admission of Successor General Partner 
  
 A successor to all of the General Partner’s General Partner Interest pursuant to Section 11.2 who is proposed to be admitted as a successor General Partner shall be admitted to the Partnership as the General Partner, effective
upon such transfer. Any such transferee shall 

  

 73 

 
carry on the business of the Partnership without dissolution. In each case, the admission shall be subject to the successor General Partner executing and
delivering to the Partnership an acceptance of all of the terms and conditions of this Agreement and such other documents or instruments as may be required to effect the admission. In the case of such admission on any day other than the first day of

Person is recorded on the books and records of the Partnership, following the receipt of the Capital Contribution in respect of such Limited Partner and the consent of the General Partner to such admission. If any Additional Limited Partner is

Limited Partner and all other Partners and Assignees by taking into account their varying interests during the Partnership Year using a method selected by the General Partner that is in accordance with the Code. Except as otherwise agreed to by the
Additional Limited Partners and the General Partner, all distributions of Available Cash with respect to which the Partnership Record Date is before the date of such admission shall be made solely to Partners and Assignees other than the Additional
Limited Partner (other than in its capacity as an Assignee) and all distributions of Available Cash thereafter shall be made to all Partners and Assignees including such Additional Limited Partner. 
  
 Section 12.3 Amendment of Agreement and Certificate of Limited Partnership

 DISSOLUTION AND LIQUIDATION 
  
 Section 13.1

 The Partnership shall not be dissolved by
the admission of Substituted Limited Partners or Additional Limited Partners or by the admission of a successor General Partner in accordance with the terms of this Agreement. Upon the withdrawal of the General Partner, any successor General Partner
(selected as described in Section 13.1.B below) shall continue the business of the Partnership. The Partnership shall dissolve, and its affairs shall be wound up, upon the first to occur of any of the following (each a “Liquidating
Event”): 
  
 A. the expiration of its term as provided
in Section 2.5; 
  
 B. an event of withdrawal of the

 G. the Redemption or exchange for REIT Shares of all Partnership Interests (other than those of the General Partner)

each case under any federal or state bankruptcy or insolvency laws as now or hereafter in effect, unless prior to the entry of such order or judgment all of the remaining Partners agree in writing to continue the business of the Partnership and to
the appointment, effective as of a date prior to the date of such order or judgment, of a substitute General Partner. 
  

 75 

 Section 13.2 Winding Up 
  

A. Upon the occurrence of a Liquidating Event, the Partnership shall continue solely for the purposes of winding up its affairs in an orderly manner,
liquidating its assets, and satisfying the claims of its creditors and Partners. No Partner shall take any action that is inconsistent with, or not necessary to or appropriate for, the winding up of the Partnership’s business and affairs. The
General Partner (or, in the event there is no remaining General Partner, any Person elected by a Majority in Interest of the Limited Partners (the “Liquidator”)) shall be responsible for overseeing the winding-up and dissolution of
the Partnership and shall take full account of the Partnership’s liabilities and property and the Partnership property shall be liquidated as promptly as is consistent with obtaining the fair value thereof, and the proceeds therefrom (which
may, to the extent determined by the General Partner, include shares of stock in the General Partner) shall be applied and distributed in the following order: 
  

(1) First, to the payment and discharge of all of the Partnership’s debts and liabilities to creditors other than the Partners; 
  
 (2) Second, to the payment and discharge of all of the Partnership’s
debts and liabilities to the General Partner; 
  
 (3) Third, to
the payment and discharge of all of the Partnership’s debts and liabilities to the other Partners; and 
  
 (4) The balance, if any, to the General Partner and Limited Partners in accordance with their positive Capital Account balances, determined after taking
into account all Capital Account adjustments for all prior periods and the Partnership taxable year during which the liquidation occurs (other than those made as a result of the liquidating distribution set forth in this Section 13.2.A(4)).

  
 The General Partner shall not receive any additional compensation for any
services performed pursuant to this Article 13 other than reimbursement of its expenses as provided in Section 7.4. 
  
 B. Notwithstanding the provisions of Section 13.2.A which require liquidation of the assets of the Partnership, but subject to the order of
priorities set forth therein, if prior to or upon dissolution of the Partnership the Liquidator determines that an immediate sale of part or all of the Partnership’s assets would be impractical or would cause undue loss to the Partners, the
Liquidator may, in its sole and absolute discretion, defer for a reasonable time the liquidation of any assets except those necessary to satisfy liabilities of the Partnership (including to those Partners as creditors) and/or distribute to the
Partners, in lieu of cash, as tenants in common and in accordance with the provisions of Section 13.2.A, undivided interests in such Partnership assets as the Liquidator deems not suitable for liquidation. Any such distributions in-kind shall
be made only if, in the good faith judgment of the Liquidator, such distributions in-kind are in the best interest of the Partners, and shall be subject to such conditions relating to the disposition and management of such properties as the
Liquidator deems reasonable and equitable and to any agreements governing the operation of such properties at such time. The Liquidator shall determine the fair market value of any property distributed in kind using such reasonable method of
valuation as it may adopt. 
  

 76 

 Section 13.3 Capital Contribution Obligation 
  
 If any Partner has a deficit balance in his or her Capital Account (after giving effect to all contributions, distributions
and allocations for the taxable years, including the year during which such liquidation occurs), such Partner shall have no obligation to make any contribution to the capital of the Partnership with respect to such deficit, and such deficit at any
time shall not be considered a debt owed to the Partnership or to any other Person for any purpose whatsoever, except to the extent otherwise expressly agreed to by such Partner and the Partnership. 
  
 Section 13.4 Compliance with Timing Requirements of Regulations 
  
 In the discretion of the Liquidator or the General Partner, a pro rata
portion of the distributions that would otherwise be made to the General Partner and Limited Partners pursuant to this Article 13 may be: 
  
 (1) distributed to a trust established for the benefit of the General Partner and Limited Partners for the purposes of liquidating Partnership assets,
collecting amounts owed to the Partnership, and paying any contingent or unforeseen liabilities or obligations of the Partnership or of the General Partner arising out of or in connection with the Partnership. The assets of any such trust shall be
distributed to the General Partner and Limited Partners from time to time, in the reasonable discretion of the Liquidator or the General Partner, in the same proportions and the amount distributed to such trust by the Partnership would otherwise
have been distributed to the General Partner and Limited Partners pursuant to this Agreement; or 
  
 (2) withheld or escrowed to provide a reasonable reserve for Partnership liabilities (contingent or otherwise) and to reflect the unrealized portion of
any installment obligations owed to the Partnership, provided, that such withheld or escrowed amounts shall be distributed to the General Partner and Limited Partners in the manner and priority set forth in Section 13.2.A as
soon as practicable. 
  
 Section 13.5 Deemed Distribution and
Recontribution 
  
 Notwithstanding any other provision of
this Article 13, in the event the Partnership is liquidated within the meaning of Regulations Section 1.704-1(b)(2)(ii)(g) but no Liquidating Event has occurred, the Partnership’s property shall not be liquidated, the Partnership’s
liabilities shall not be paid or discharged, and the Partnership’s affairs shall not be wound up. Instead, the Partnership shall be deemed to have contributed all of its assets and liabilities to a new partnership in exchange a for an interest
in the new partnership. Immediately thereafter, the Partnership shall be deemed to distribute interests in the new partnership to the General Partner and Limited Partners in proportion to their respective interests in the Partnership in liquidation
of the Partnership. 
  
 Section 13.6 Rights of Limited Partners 

 
 Except as otherwise provided in this Agreement, each Limited Partner
shall look solely to the assets of the Partnership for the return of his Capital Contribution and shall have no right or power to demand or receive property from the General Partner. No Limited Partner shall have priority over any other Limited
Partner as to the return of his Capital Contributions, distributions or allocations. 
  

 77 

 Section 13.7 Notice of Dissolution 
  
 In the event a Liquidating Event occurs or an event occurs that would, but for provisions of Section 13.1, result in
a dissolution of the Partnership, the General Partner shall, within 30 days thereafter, provide written notice thereof to each of the Partners and to all other parties with whom the Partnership regularly conducts business (as determined in the
discretion of the General Partner) and shall publish notice thereof in a newspaper of general circulation in each place in which the Partnership regularly conducts business (as determined in the discretion of the General Partner). 
  
 Section 13.8 Cancellation of Certificate of Limited Partnership 
  
 Upon the completion of the liquidation of the Partnership cash and property
as provided in Section 13.2, the Partnership shall be terminated and the Certificate and all qualifications of the Partnership as a foreign limited partnership in jurisdictions other than the State of Maryland shall be cancelled and such
other actions as may be necessary to terminate the Partnership shall be taken. 
  
 Section 13.9 Reasonable Time for Winding-Up 
  
 A
reasonable time shall be allowed for the orderly winding-up of the business and affairs of the Partnership and the liquidation of its assets pursuant to Section 13.2, in order to minimize any losses otherwise attendant upon such winding-up,
and the provisions of this Agreement shall remain in effect between the Partners during the period of liquidation. 
  
 Section 13.10 Waiver of Partition 
  
 Each Partner hereby waives any right to partition of the Partnership property. 
  
 ARTICLE 14.

 Section 14.1
Amendments 
  
 A. The actions requiring consent or
approval of the Partners or of the Limited Partners pursuant to this Agreement, including Section 7.3, or otherwise pursuant to applicable law, are subject to the procedures in this Article 14. 
  
 B. Amendments to this Agreement requiring the consent or approval of Limited
Partners may be proposed by the General Partner or by Limited Partners holding twenty-five percent (25%) or more of the Partnership Interests held by Limited Partners. The General Partner shall seek the written consent of the Limited Partners on the
proposed amendment or shall call a meeting to vote thereon and to transact any other business that it may deem appropriate. For purposes of obtaining a written consent, the General Partner may require a response within a reasonable specified time,
but not less than 15 days, and failure to respond in 

  

 78 

 
such time period shall constitute a consent which is consistent with the General Partner’s recommendation (if so recommended) with respect to the
proposal; provided, that, an action shall become effective at such time as requisite consents are received even if prior to such specified time. 
  

Section 14.2 Action by the Partners 
  
 A. Meetings of the Partners may be called by the General Partner and shall be called upon the receipt by the General Partner of a written request by

 A series of Partnership Units in the Partnership designated as the “8.5% Series A Cumulative Redeemable Preferred Units” (the “Series A
Preferred Units”) is hereby established. The number of Series A Preferred Units shall be 4,140,000. 
  
 Section 16.2 Distributions 
  
 A. Payment of Distributions. Subject to the rights of Holders of Parity Preferred Units as to the payment of distributions, pursuant to Section 5.1, the General Partner, as holder of the Series A Preferred Units, will be entitled to
receive, when, as and if declared by the Partnership acting through the General Partner, out of Available Cash, cumulative preferential cash distributions in an amount equal to the Series A Priority Return. Such distributions shall be cumulative,
shall accrue from the original date of issuance and will be payable (i) quarterly (such quarterly periods for purposes of payment and accrual will be the quarterly periods ending on the dates specified in this sentence and not calendar quarters) in
arrears, on the last calendar day of March, June, September and December, of each year commencing on the first of such dates to occur after the original date of issuance, and, (ii), in the event of a redemption of Series A Preferred Units, on the
redemption date (each a “Series A Preferred Unit Distribution Payment  

  

 81 

 
Date”). If any date on which distributions are to be made on the Series A Preferred Units is not a Business Day, then payment of the distribution
to be made on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay) except that, if such Business Day is in the next succeeding calendar year, such payment
shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date. 
  
 B. Distributions Cumulative. Notwithstanding the foregoing, distributions on the Series A Preferred Units will accrue whether or not the terms and
provisions set forth in Section 16.2.C hereof at any time prohibit the current payment of distributions, whether or not the Partnership has earnings, whether or not there are funds legally available for the payment of such distributions and
whether or not such distributions are authorized. 
  
 C.
Priority as to Distributions 
  
 (i) Except as provided
in Section 16.2.C.(ii) below, no distributions shall be declared or paid or set apart for payment and no other distribution of cash or other property may be declared or made on or with respect to any Parity Preferred Unit or Junior Unit as to
distributions (other than a distribution paid in Junior Units as to distributions and upon liquidation) for any period, nor shall any Junior Units or Parity Preferred Units as to distributions or upon liquidation be redeemed, purchased or otherwise
acquired for any consideration (and no funds shall be paid or made available for a sinking fund for the redemption of such units) and no other distribution of cash or other property may be made, directly or indirectly, on or with respect thereto by
the Partnership (except by conversion into or exchange for Junior Units as to distributions and upon liquidation, and except for the redemption of Partnership Interests corresponding to any REIT Series A Preferred Shares or any other REIT shares of
any other class or series of capital stock ranking, as to dividends or upon liquidation, on parity with or junior to the Series A Preferred Stock to be purchased by the General Partner pursuant to the Charter to the extent necessary to preserve the
General Partner’s status as a real estate investment trust, provided that such redemption shall be upon the same terms as the corresponding stock purchase pursuant to the Charter), unless full cumulative distributions on the Series A
Preferred Units for all past periods and the then current period shall have been or contemporaneously are (i) declared and paid in cash or (ii) declared and a sum sufficient for the payment thereof in cash is set apart for such payment. 

 
 (ii) When distributions are not paid in full (and a sum sufficient for
such full payment is not so set apart) upon the Series A Preferred Units and any other Parity Preferred Units as to distributions, all distributions declared upon the Series A Preferred Units and such other classes or series of Parity Preferred
Units as to the payment of distributions shall be declared pro rata so that the amount of distributions declared per Series A Preferred Unit and each such other class or series of Parity Preferred Units shall in all cases bear to each other the same
ratio that accrued distributions per Series A Preferred Unit and such other class or series of Parity Preferred Units (which shall not include any accrual in respect of unpaid distribution on such other class or series of Parity Preferred Units for
prior distribution periods if such other class or series of Parity Preferred Unit does not have a cumulative distribution) bear to each other. No interest, or sum of money in lieu of interest, shall be payable in respect of any distribution payment
or payments on the Series A Preferred Units which may be in arrears. 
  

 82 

 D. No Further Rights. The General Partner, as holder of the Series A Preferred Units, shall not be
entitled to any distributions, whether payable in cash, other property or otherwise, in excess of the full cumulative distributions described herein. Any distribution payment made on the Series A Preferred Units shall first be credited against the
earliest accrued but unpaid distribution due with respect to such Series A Preferred Units which remains payable. Accrued but unpaid distributions on the Series A Preferred Units will accumulate as of the Series A Preferred Unit Distribution Payment
Date on which they first become payable. 
  
 Section 16.3 Liquidation
Proceeds 
  
 A. Distributions. Upon any voluntary or
involuntary liquidation, dissolution or winding-up of the affairs of the Partnership, distributions on the Series A Preferred Units shall be made in accordance with Article 13 hereof. 
  
 B. Notice. Written notice of any such voluntary or involuntary
liquidation, dissolution or winding-up of the Partnership, stating the payment date or dates when, and the place or places where, the amounts distributable in such circumstances shall be payable, shall be given by the General Partner pursuant to
Section 13.7 hereof. 
  
 C. No Further Rights. After
payment of the full amount of the liquidating distributions to which they are entitled, the General Partner, as holder of the Series A Preferred Units, will have no right or claim to any of the remaining assets of the Partnership. 
  
 D. Consolidation, Merger or Certain Other Transactions. The voluntary
sale, conveyance, lease, exchange or transfer (for cash, shares of stock, securities or other consideration) of all or substantially all of the property or assets of the Partnership to, or the consolidation or merger or other business combination of
the Partnership with or into, any corporation, trust or other entity (or of any corporation, trust or other entity with or into the Partnership) shall not be deemed to constitute a liquidation, dissolution or winding-up of the Partnership.

  
 Section 16.4 Redemption 
  
 A. Redemption. If the General Partner elects to redeem any of the
REIT Series A Preferred Shares in accordance with the terms of the Series A Articles Supplementary, the Partnership shall, on the date set for redemption of such REIT Series A Preferred Shares, redeem the number of Series A Preferred Units equal to
the number of REIT Series A Preferred Shares for which the General Partner has given notice of redemption pursuant to Section 5 of Article THIRD of the Series A Articles Supplementary, at a redemption price, payable in cash, equal to
the product of (i) the number of Series A Preferred Units being redeemed, and (ii) the sum of $25, any Preferred Distribution Shortfall per Series A Preferred Unit, and any accrued and unpaid distribution per Series A Preferred Unit for the current
distribution period. 
  
 B. Procedures for Redemption. The
following provisions set forth the procedures for redemption: 
  
 (i) Notice of redemption will be given by the General Partner to the Partnership concurrently with the notice of the General Partner sent to the holders of its 

  

 83 

 
REIT Series A Preferred Shares in connection with such redemption. Such notice shall state: (A) the redemption date; (B) the redemption price; (C) the number
of Series A Preferred Units to be redeemed; (D) the place or places where the Series A Preferred Units are to be surrendered for payment of the redemption price; and (E) that distributions on the Series A Preferred Units to be redeemed will cease to
accumulate on such redemption date. If less than all of the Series A Preferred Units are to be redeemed, the notice shall also specify the number of Series A Preferred Units to be redeemed. 
  
 (ii) On or after the redemption date, the General Partner shall present and
surrender the certificates, if any, representing the Series A Preferred Units to the Partnership at the place designated in the notice of redemption and thereupon the redemption price of such Units (including all accumulated and unpaid distributions
up to but excluding the redemption date) shall be paid to the General Partner and each surrendered Unit certificate, if any, shall be canceled. If fewer than all the Units represented by any such certificate representing Series A Preferred Units are
to be redeemed, a new certificate shall be issued representing the unredeemed shares. 
  
 (iii) From and after the redemption date (unless the Partnership defaults in payment of the redemption price), all distributions on the Series A Preferred Units designated for redemption in such notice shall cease to
accumulate and all rights of the General Partner, except the right to receive the redemption price thereof (including all accumulated and unpaid distributions up to but excluding the redemption date), shall cease and terminate, and such Series A
Preferred Units shall not be deemed to be outstanding for any purpose whatsoever. At its election, the Partnership, prior to a redemption date, may irrevocably deposit the redemption price (including accumulated and unpaid distributions to but not
including the redemption date) of the Series A Preferred Units so called for redemption in trust for the General Partner with a bank or trust company, in which case the redemption notice to the General Partner shall (A) state the date of such
deposit, (B) specify the office of such bank or trust company as the place of payment of the redemption price and (C) require the General Partner to surrender the certificates, if any, representing such Series A Preferred Units at such place on or
about the date fixed in such redemption notice (which may not be later than the redemption date) against payment of the redemption price (including all accumulated and unpaid distributions to the redemption date). Any monies so deposited which
remain unclaimed by the General Partner at the end of two years after the redemption date shall be returned by such bank or trust company to the Partnership. 
  
 Section 16.5 Ranking 
  
 The Series A Preferred Units shall, with respect to distribution rights and rights upon voluntary or involuntary liquidation, winding-up or dissolution of
the Partnership, rank (i) senior to the Common Units and to all other Partnership Units the terms of which provide that such Partnership Units shall rank junior to the Series A Preferred Units; (ii) on a parity with all Parity Preferred Units,
including the Series B Preferred Units; and (iii) junior to all Partnership Units which rank senior to the Series A Preferred Units.

(such quarterly periods for purposes of payment and accrual will be the quarterly periods ending on the dates specified in this sentence and not calendar quarters) in arrears, on the last calendar day of March, June, September and December, of each
year commencing on the first of such dates to occur after the original date of issuance, and, (ii), in the event of a redemption of Series B Preferred Units, on the redemption date (each a “Series B Preferred Unit Distribution Payment
Date”). If any date on which distributions are to be made on the Series B Preferred Units is not a Business Day, then payment of the distribution to be made on such date will be made on the next succeeding day that is a Business Day (and
without any interest or other payment in respect of any such delay) except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and

Preferred Stock to be purchased by the General Partner pursuant to the Charter to the extent necessary to preserve the General Partner’s status as a real estate investment trust, provided that such redemption shall be upon the same terms
as the corresponding stock purchase pursuant to the Charter), unless full cumulative distributions on the Series B Preferred Units for all past periods shall have been or contemporaneously are (i) declared and paid in cash or (ii) declared and a sum
sufficient for the payment thereof in cash is set apart for such payment.

distributions declared upon the Series B Preferred Units and such other classes or series of Parity Preferred Units as to the payment of distributions shall be declared pro rata so that the amount of distributions declared per Series B Preferred
Unit and each such other class or series of Parity Preferred Units shall in all cases bear to each other the same ratio that accrued distributions per Series B Preferred Unit and such other class or series of Parity Preferred Units (which shall not
include any accrual in respect of unpaid distribution on such other class or series of Parity Preferred Units for prior distribution periods if such other class or series of Parity Preferred Unit does not have a cumulative distribution) bear to each
other. No interest, or sum of money in lieu of interest, shall be payable in respect of any distribution payment or payments on the Series B Preferred Units which may be in arrears.

 EXHIBIT C 
  

CONSTRUCTIVE OWNERSHIP DEFINITION 
  
 The term “Constructively Owns” means ownership determined through the application of the constructive ownership rules of Section 318 of the
Code, as modified by Section 856(d)(5) of the Code. Generally, these rules provide the following: 
  
 a. an individual is considered as owning the Ownership Interest that is owned, actually or constructively, by or for his spouse, his children, his
grandchildren, and his parents; 
  
 b. an Ownership Interest that
is owned, actually or constructively, by or for a partnership, limited liability company or estate is considered as owned proportionately by its partners or beneficiaries; 
  
 c. an Ownership Interest that is owned, actually or constructively, by or for a trust is considered as owned by its
beneficiaries in proportion to the actuarial interest of such beneficiaries (provided, however, that in the case of a “grantor trust” the Ownership Interest will be considered as owned by the grantors); 
  
 d. if ten (10) percent or more in value of the stock in a corporation is
owned, actually or constructively, by or for any person, such person shall be considered as owning the Ownership Interest that is owned, actually or constructively, by or for such corporation in that proportion which the value of the stock which
such person so owns bears to the value of all the stock in such corporation; 
  
 e. an Ownership Interest that is owned, actually or constructively, by or for a partner or member which actually or constructively owns a 25% or greater capital interest or profits interest in a partnership or limited
liability company, or by or to or for a beneficiary of an estate or trust shall be considered as owned by the partnership, limited liability company, estate, or trust (or, in the case of a grantor trust, the grantors); 
  
 f. if ten (10) percent or more in value of the stock in a corporation is
owned, actually or constructively, by or for any person, such corporation shall be considered as owning the Ownership Interest that is owned, actually or constructively, by or for such person; 
  
 g. if any person has an option to acquire an Ownership Interest (including an
option to acquire an option or any one of a series of such options), such Ownership Interest shall be considered as owned by such person; 
  
 h. an Ownership Interest that is constructively owned by a person by reason of the application of the rules described in paragraphs (a) through (g) above
shall, for purposes of applying paragraphs (a) through (g), be considered as actually owned by such person provided, however, that (i) an Ownership Interest constructively owned by an individual by reason of paragraph (a) shall not be
considered as owned by him for purposes of again applying paragraph (a) in order to make another the constructive owner of such Ownership Interest, (ii) an Ownership Interest constructively owned by a partnership, estate, trust, or corporation by
reason 

  

 C-1 

 
of the application of paragraphs (e) or (f) shall not be considered as owned by it for purposes of applying paragraphs (b), (c), or (d) in order to make
another the constructive owner of such Ownership Interest, (iii) if an Ownership Interest may be considered as owned by an individual under paragraphs (a) or (g), it shall be considered as owned by him under paragraph (g), and (iv) for purposes of
the above described rules, an S corporation shall be treated as a partnership and any stockholder of the S corporation shall be treated as a partner of such partnership except that this rule shall not apply for purposes of determining whether stock
in the S corporation is constructively owned by any person. 
  
 i.
For purposes of the above summary of the constructive ownership rules, the term “Ownership Interest” means the ownership of stock with respect to a corporation and, with respect to any other type of entity, the ownership of an interest in
either its assets or net profits.
