 Exhibit 10.103 
 Guaranty Agreement 
 This Guaranty
Agreement (this “Guaranty”) is made as of the 19th day of June, 2013, by KBS REIT Properties III, LLC, a Delaware limited liability company (“Guarantor”), in favor of Bank of America, N.A., a national banking association (together
with its successors and assigns, “Lender”). 
 Recitals 

KBSIII Preston Commons, LLC, a Delaware limited liability company, KBSIII Sterling Plaza, LLC, a Delaware limited
liability company and KBSIII One Washingtonian, LLC, a Delaware limited liability company (each a “Borrower,” and, collectively, “Borrowers”), have requested that Lender make a loan (the
“Loan”) to Borrowers evidenced by a Promissory Note of even date herewith in the original principal amount of One Hundred Seventy Million Seven Hundred Sixty Thousand and No/100 Dollars ($170,760,000.00) made by Borrowers to
the order of Lender (as the same may from time to time be amended, supplemented, restated or otherwise modified, the “Note”). Certain terms and conditions of the Loan are set forth in the Term Loan Agreement of even date
herewith between Borrower and Lender (as the same may from time to time be amended, supplemented, restated or otherwise modified, the “Loan Agreement”). As a condition precedent to making the Loan, Lender has required that
Guarantor execute and deliver this Guaranty to Lender. Any capitalized term used and not defined in this Guaranty shall have the meaning given to such term in the Loan Agreement. 

Agreements 
 For good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, and in order to induce Lender to make the Loan to Borrowers, Guarantor hereby guarantees to Lender the
prompt and full payment and performance of the indebtedness and obligations described below in this Guaranty (collectively called the “Guaranteed Obligations”), this Guaranty being upon the following terms and conditions:

 Section 1.      Guaranty of Payment. 

Guarantor hereby unconditionally and irrevocably guarantees to Lender the punctual payment when due, whether by lapse of
time, by acceleration of maturity, or otherwise, of (i) upon the occurrence of a Triggering Event (as hereinafter defined), all principal and interest (including interest accruing after maturity and after the commencement of any bankruptcy or
insolvency proceeding by or against any Borrower, whether or not allowed in such proceeding) now or hereafter due and owing, or which any Borrower is obligated to pay, pursuant to the terms of the Note, the Loan Agreement, the Security Instruments,
or any of the other Loan Documents, as the same may from time to time be amended, supplemented, restated or otherwise modified, and (ii) regardless of whether a Triggering Event shall have occurred, 100% of all amounts owing under the
Environmental Agreements by Borrowers if (and only if) the Environmental Insurance Policy (as defined in and substantially and materially in the form approved by Lender pursuant to the Loan Agreement) is not then in place or, if not then in place,
does not otherwise cover a Borrower for claims relating to environmental matters when and if demand is made by Lender under the Environmental Agreement delivered by such Borrower 

  
 1 








 
(i.e., Guarantor shall have no liability under this Guaranty for, and the Indebtedness (as hereinafter defined) shall not include, amounts owing under any of the Environmental Agreements so
long as the Environmental Insurance Policy is in place or otherwise covers the liability of a Borrower for environmental matters at the time demand is made by Lender to such Borrower under the Environmental Agreement delivered by such Borrower,
whether or not the claim relating to any such environmental matter is a covered claim under such Environmental Insurance Policy) (the amounts described in clauses (i) and (ii) above shall be referred to herein, collectively, as the
“Indebtedness”). The Indebtedness shall also include all costs and expenses incurred by Lender in seeking to enforce Lender’s rights and remedies under this Guaranty, including court costs, costs of
alternative dispute resolution and reasonable attorneys’ fees, whether or not suit is filed or other proceedings are initiated thereon. This Guaranty covers, subject to the other terms and conditions of this Guaranty, the Indebtedness presently
outstanding and the Indebtedness arising subsequent to the date hereof, including all amounts advanced by Lender in stages or installments. The guaranty of Guarantor as set forth in this Section 1 is a continuing guaranty of payment and
not a guaranty of collection. 
 Section 2.      Intentionally
Omitted. 
 Section 3.      Guaranty of Specific Obligations.

 Guarantor also hereby unconditionally and irrevocably guarantees payment of, and agrees to protect, defend,
indemnify and hold harmless Lender for, from and against, 100% of any deficiency, loss or damage suffered by Lender because of: 
 (a)      The intentional misapplication or misappropriation by any Borrower of any funds derived from the Property of such Borrower, including the misapplication or
misappropriation by any Borrower of rent, security deposits, insurance proceeds, condemnation awards, or other income arising with respect to any Property; 
 (b)      any Borrower’s intentional commission of physical waste with respect to any Property; 

(c)      The fraud or intentional misrepresentation by any Borrower or Guarantor made in
or in connection with the Loan Documents or the Loan; 
 (d)      any voluntary
transfer of the Property in violation of the terms of the Loan Documents; or 

(e)      any Borrower’s voluntary filing of any proceeding for relief under any
federal or state bankruptcy, insolvency or receivership laws or any assignment for the benefit of creditors made by any Borrower, or the involuntary filing against any Borrower by any member of any Borrower, Guarantor or any Affiliate thereof of any
proceeding for relief under any federal or state bankruptcy, insolvency or receivership laws, and such proceeding is not dismissed within ninety (90) days of the filing thereof (a “Triggering Event”). 

  
 2 








 Section 4.      Primary Liability of
Guarantor. 
 (a)      This Guaranty is an absolute, irrevocable and
unconditional guaranty of payment and performance, and Guarantor shall be liable for the payment and performance of the Guaranteed Obligations as a primary obligor. This Guaranty shall be effective as a waiver of, and Guarantor hereby expressly
waives, any right to which Guarantor may otherwise have been entitled, whether existing under statute, at Law or in equity, to require Lender to take prior recourse or proceedings against any collateral, security or Person. It shall not be necessary
for Lender, in order to enforce such payment or performance by Guarantor, first to institute suit or pursue or exhaust any rights or remedies against any Borrower or other Person liable on such indebtedness or for such performance, or to enforce any
rights against any security given to secure such indebtedness or performance, or to join any Borrower or any other Person liable for the payment or performance of the Guaranteed Obligations or any part thereof in any action to enforce this Guaranty,
or to resort to any other means of obtaining payment or performance of the Guaranteed Obligations; provided, however, that nothing herein contained shall prevent Lender from suing on the Note or foreclosing the Security Instruments or exercising any
other right under the Loan Documents. 
 (b)      Suit may be brought or demand
may be made against any Borrower or against any or all parties who have signed this Guaranty or any other guaranty covering all or any part of the Guaranteed Obligations, or against any one or more of them, separately or together, without impairing
the rights of Lender against any party hereto. 
 Section 5.      Certain
Agreements and Waivers by Guarantor. 
 (a)      Guarantor agrees that neither
Lender’s rights or remedies nor Guarantor’s obligations under the terms of this Guaranty shall be released, diminished, impaired, reduced or affected by any one or more of the following events, actions, facts, or circumstances, Guarantor
waives any rights, claims or defenses arising from any such events, actions, facts, or circumstances, and the liability of Guarantor under this Guaranty shall be absolute, unconditional and irrevocable irrespective of: 

(i)       any limitation on the liability of, or recourse against,
any other Person in any Loan Document or arising under any Law; 

(ii)      any claim or defense that this Guaranty was made without
consideration or is not supported by adequate consideration or that the obligations of Guarantor hereunder exceed or are more burdensome than those of Borrowers under the other Loan Documents; 

(iii)    the taking or accepting of any other security or guaranty for, or right of
recourse with respect to, any or all of the Guaranteed Obligations; 

(iv)    the operation of any statutes of limitation or other Laws regarding the
limitation of actions, all of which are hereby waived as a defense to any action or proceeding brought by Lender against Guarantor, to the fullest extent permitted by Law; 

  
 3 








 (v)     any homestead exemption or
any other exemption under applicable Law; 
 (vi)    any release,
surrender, abandonment, exchange, alteration, sale or other disposition, subordination, deterioration, waste, failure to protect or preserve, impairment, or loss of, or any failure to create or perfect any lien or security interest with respect to,
or any other dealings with, any collateral or security at any time existing or purported, believed or expected to exist in connection with any or all of the Guaranteed Obligations, or any impairment of Guarantor’s recourse against any Person or
collateral; 
 (vii)    whether express or by operation of Law, any partial
release of the liability of Guarantor hereunder (except to the extent expressly so released) or any complete or partial release of any Borrower or any other Person liable, directly or indirectly, for the payment or performance of any or all of the
Guaranteed Obligations; 
 (viii)    the death, insolvency, bankruptcy,
disability, dissolution, liquidation, termination, receivership, reorganization, merger, consolidation, change of form, structure or ownership, sale of all assets, or lack of corporate, partnership or other power of any Borrower or any other Person
at any time liable for the payment or performance of any or all of the Guaranteed Obligations; 

(ix)    either with or without notice to or consent of Guarantor, any renewal,
extension, modification, supplement, subordination or rearrangement of the terms of any or all of the Guaranteed Obligations and/or any of the Loan Documents, including material alterations of the terms of payment (including changes in maturity
date(s) and interest rate(s)) or performance (including changes with respect to the construction of the Improvements) or any other terms thereof, or any waiver, termination, or release of, or consent to departure from, any of the Loan Documents or
any other guaranty of any or all of the Guaranteed Obligations, or any adjustment, indulgence, forbearance, or compromise that may be granted from time to time by Lender to any Borrower or any other Person at any time liable for the payment or
performance of any or all of the Guaranteed Obligations; 
 (x)    any
neglect, lack of diligence, delay, omission, failure, or refusal of Lender to take or prosecute (or in taking or prosecuting) any action for the collection or enforcement of any of the Guaranteed Obligations, or to foreclose or take or prosecute any
action to foreclose (or in foreclosing or taking or prosecuting any action to foreclose) upon any security therefor, or to exercise (or in exercising) any other right or power with respect to any security therefor, or to take or prosecute (or in
taking or prosecuting) any action in connection with any Loan Document, or any failure to sell or otherwise dispose of in a commercially reasonable manner any collateral securing any or all of the Guaranteed Obligations; 

(xi)    any failure of Lender to notify Guarantor of any creation, renewal,
extension, rearrangement, modification, supplement, subordination, or assignment of the Guaranteed Obligations or any part thereof, or of any Loan Document, or of any release of or change in any security, or of the occurrence or existence of any
Default or Event of 

  
 4 








 
Default, or of any other action taken or refrained from being taken by Lender against any Borrower or any security or other recourse, or of any new agreement between Lender and any Borrower, it
being understood that Lender shall not be required to give Guarantor any notice of any kind under any circumstances with respect to or in connection with the Guaranteed Obligations, any and all rights to notice Guarantor may have otherwise had being
hereby waived by Guarantor, and Guarantor shall be responsible for obtaining for itself information regarding each Borrower and any collateral, including any changes in the business or financial condition of each Borrower or any collateral, and
Guarantor acknowledges and agrees that Lender shall have no duty to notify Guarantor of any information which Lender may have concerning any Borrower or any collateral; 

(xii)    the existence of any claim, counterclaim, set-off or other right that
Guarantor may at any time have against Borrower, Lender, or any other Person, whether or not arising in connection with this Guaranty, the Note, the Loan Agreement or any other Loan Document; 

(xiii)    the unenforceability of all or any part of the Guaranteed Obligations
against any Borrower, whether because the Guaranteed Obligations exceed the amount permitted by Law or violate any usury law, or because the Persons creating the Guaranteed Obligations acted in excess of their authority, or because of a lack of
validity or enforceability of or defect or deficiency in any of the Loan Documents, or because any Borrower has any valid defense, claim or offset with respect thereto, or because any Borrower’s obligation ceases to exist by operation of Law,
or because of any other reason or circumstance, it being agreed that Guarantor shall remain liable hereon regardless of whether any Borrower or any other Person be found not liable on the Guaranteed Obligations, or any part thereof, for any reason
(and regardless of any joinder of any Borrower or any other party in any action to obtain payment or performance of any or all of the Guaranteed Obligations); 

(xiv)    any order, ruling or plan of reorganization emanating from proceedings
under Title 11 of the United States Code with respect to any Borrower or any other Person, including any extension, reduction, composition, or other alteration of the Guaranteed Obligations, whether or not consented to by Lender, or any action taken
or omitted by Lender in any such proceedings, including any election to have Lender’s claim allowed as being secured, partially secured or unsecured, any extension of credit by Lender in any such proceedings or the taking and holding by Lender
of any security for any such extension of credit; 
 (xv)    any other
condition, event, omission, action or inaction that would in the absence of this paragraph result in the release or discharge of the Guarantor from the performance or observance of any obligation, covenant or agreement contained in this Guaranty or
any other agreement; 
 (xvi)    any early termination of any of the
Guaranteed Obligations; or 
 (xvii)  Lender’s enforcement or forbearance from
enforcement of the Guaranteed Obligations on a net or gross basis. 

  
 5 








 (b)      In the event any payment by any
Borrower or any other Person to Lender is held to constitute a preference, fraudulent transfer or other voidable payment under any bankruptcy, insolvency or similar Law, or if for any other reason Lender is required to refund such payment or pay the
amount thereof to any other party, such payment by any Borrower or any other party to Lender shall not constitute a release of Guarantor from any liability hereunder, and this Guaranty shall continue to be effective or shall be reinstated
(notwithstanding any prior release, surrender or discharge by Lender of this Guaranty or of Guarantor), as the case may be, with respect to, and this Guaranty shall apply to, any and all amounts so refunded by Lender or paid by Lender to another
Person (which amounts shall constitute part of the Guaranteed Obligations), and any interest paid by Lender and any attorneys’ fees, costs and expenses paid or incurred by Lender in connection with any such event. 

(c)      It is the intent of Guarantor and Lender that the obligations and liabilities of
Guarantor hereunder are absolute, irrevocable and unconditional under any and all circumstances and that until the Guaranteed Obligations are fully and finally paid and performed, and not subject to refund or disgorgement, the obligations and
liabilities of Guarantor hereunder shall not be discharged or released, in whole or in part, by any act or occurrence that might, but for the provisions of this Guaranty, be deemed a legal or equitable discharge or release of a guarantor.

 (d)      Guarantor’s obligations shall not be affected, impaired, lessened
or released by loans, credits or other financial accommodations now existing or hereafter advanced by Lender to any Borrower in excess of the Guaranteed Obligations. All payments, repayments and prepayments of the Loan, whether voluntary or
involuntary, received by Lender from any Borrower, any other Person or any other source (other than from Guarantor pursuant to a demand by Lender hereunder), and any amounts realized from any collateral for the Loan, shall be deemed to be applied
first to any portion of the Loan which is not covered by this Guaranty, and last to the Guaranteed Obligations, and this Guaranty shall bind Guarantor to the extent of any Guaranteed Obligations that may remain owing to Lender. Lender shall have the
right to apply any sums paid by Guarantor to any portion of the Loan in Lender’s sole and absolute discretion. 
 (e)      If acceleration of the time for payment of any amount payable by Borrower under the Note, the Loan Agreement, or any other Loan Document is stayed or delayed by any
Law or tribunal, all such amounts shall nonetheless be payable by Guarantor on demand by Lender. 

(f)      Guarantor unconditionally and irrevocably waives any rights, defenses or remedies
Guarantor may have under (i) Section 17.001 of the Texas Civil Practice and Remedies Code, Texas Rule of Civil Procedure 31, and Chapter 43 of the Texas Civil Practice and Remedies Code, entitled Principal and Surety, including notice,
discharge, levy and subrogation, and (ii) Sections 51.003 through 51.005 of the Texas Property Code, relating to deficiency judgments. 
 Section 6.       Subordination. 
 If, for any reason whatsoever, any Borrower is now or hereafter becomes indebted to Guarantor: 

  
 6 








 (a)      such indebtedness and all interest
thereon and all liens, security interests and rights now or hereafter existing with respect to property of such Borrower securing such indebtedness shall, at all times, be subordinate in all respects to the Guaranteed Obligations and to all liens,
security interests and rights now or hereafter existing to secure the Guaranteed Obligations; 

(b)      Guarantor shall not be entitled to enforce or receive payment, directly or
indirectly, of any such indebtedness of such Borrower to Guarantor until the Guaranteed Obligations have been fully and finally paid and performed; provided, however, that so long as no Default shall have occurred and be continuing, Guarantor shall
not be prohibited from receiving such (i) reasonable management fees or reasonable salary from such Borrower as Lender may find acceptable from time to time in its sole and absolute discretion, and (ii) distributions from such Borrower in
an amount equal to any income taxes imposed on Guarantor which are attributable to such Borrower’s income from the Property of such Borrower; 
 (c)      Guarantor hereby assigns and grants to Lender a security interest in all such indebtedness and security therefor, if any, of such Borrower to Guarantor now existing
or hereafter arising, including any dividends and payments pursuant to debtor relief or insolvency proceedings referred to below. In the event of receivership, bankruptcy, reorganization, arrangement or other debtor relief or insolvency proceedings
involving such Borrower as debtor, Lender shall have the right to prove its claim in any such proceeding so as to establish its rights hereunder and shall have the right to receive directly from the receiver, trustee or other custodian (whether or
not an Event of Default shall have occurred or be continuing under any of the Loan Documents), dividends and payments that are payable upon any obligation of such Borrower to Guarantor now existing or hereafter arising, and to have all benefits of
any security therefor, until the Guaranteed Obligations have been fully and finally paid and performed. If, notwithstanding the foregoing provisions, Guarantor should receive any payment, claim or distribution that is prohibited as provided above in
this Section 6, Guarantor shall pay the same to Lender immediately, Guarantor hereby agreeing that it shall receive the payment, claim or distribution in trust for Lender and shall have absolutely no dominion over the same except to pay
it immediately to Lender; and 
 (d)      Guarantor shall promptly upon written
request of Lender from time to time execute such documents and perform such acts as Lender may reasonably require to evidence and perfect its interest and to permit or facilitate exercise of its rights under this Section 6, including
execution and delivery of proofs of claim, further assignments and security agreements, and delivery to Lender of any promissory notes or other instruments evidencing indebtedness of such Borrower to Guarantor. All promissory notes, accounts
receivable ledgers or other evidences, now or hereafter held by Guarantor, of obligations of Borrower to Guarantor shall contain a specific written notice thereon that the indebtedness evidenced thereby is subordinated under and is subject to the
terms of this Guaranty. 
 Section 7.      Other Liability of Guarantor or
Borrowers. 
 If Guarantor is or becomes liable, by endorsement or otherwise, for any indebtedness owing by
any Borrower to Lender other than under this Guaranty, such liability shall not be in any manner impaired or affected hereby, and the rights of Lender hereunder shall be cumulative 

  
 7 








 
of any and all other rights that Lender may have against Guarantor. If any Borrower is or becomes indebted to Lender for any indebtedness other than or in excess of the Guaranteed Obligations,
any payment received or recovery realized upon such other indebtedness of such Borrower to Lender may be applied to such other indebtedness. This Guaranty is independent of (and shall not be limited by) any other guaranty now existing or hereafter
given. Further, Guarantor’s liability under this Guaranty is in addition to any and all other liability Guarantor may have in any other capacity, including, if applicable, its capacity as a general partner. 

Section 8.      Lender Assigns; Disclosure of Information. 

This Guaranty is for the benefit of Lender and Lender’s successors and assigns, and in the event of an assignment of
the Guaranteed Obligations, or any part thereof, the rights and benefits hereunder, to the extent applicable to the Guaranteed Obligations so assigned, may be transferred with such Guaranteed Obligations. Guarantor waives notice of any transfer or
assignment of the Guaranteed Obligations or any part thereof. Lender may sell or offer to sell the Loan or interests therein to one or more assignees or participants. Guarantor shall execute, acknowledge and deliver any and all instruments
reasonably requested by Lender in connection therewith (at no cost, expense, liability or potential liability to Guarantor and provided that such instruments will not modify or affect Guarantor’s rights or obligations under this Guaranty), and
to the extent, if any, specified in any such assignment or participation, such assignee(s) or participant(s) shall have the same rights and benefits with respect to the Loan Documents as such Person(s) would have if such Person(s) were Lender
hereunder. Lender may disclose to any such assignee or participant or prospective assignee or participant, to Lender’s affiliates, including Merrill Lynch, Pierce, Fenner & Smith Incorporated, to any regulatory body having jurisdiction
over Lender and to any other parties as necessary or appropriate in Lender’s reasonable judgment, any information Lender now has or hereafter obtains pertaining to the Guaranteed Obligations, this Guaranty, or Guarantor, including information
regarding any security for the Guaranteed Obligations or for this Guaranty, and/or credit or other information on Guarantor and/or any other Person liable, directly or indirectly, for any part of the Guaranteed Obligations. 

Section 9.      Binding Effect; Joint and Several Liability. 

This Guaranty is binding not only on Guarantor, but also on Guarantor’s heirs, personal representatives, successors
and assigns. Upon the death of Guarantor, if Guarantor is a natural person, this Guaranty shall continue against Guarantor’s estate as to all of the Guaranteed Obligations, including that portion incurred or arising after the death of Guarantor
and shall be provable in full against Guarantor’s estate, whether or not the Guaranteed Obligations are then due and payable. If this Guaranty is signed by more than one Person, then all of the obligations of Guarantor arising hereunder shall
be jointly and severally binding on each of the undersigned, and their respective heirs, personal representatives, successors and assigns, and the term “Guarantor” shall mean all of such Persons and each of them individually.

 Section 10.    Governing Law. 

This Guaranty is an agreement executed under seal. If any Guarantor is a corporation, the designation “(SEAL)”
on this Guaranty shall be effective as the affixing of such Guarantor’s corporate seal physically to this Guaranty. The validity, enforcement, and interpretation of this 

  
 8 








 
Guaranty, shall for all purposes be governed by and construed in accordance with the laws of the State of Texas and applicable United States federal law, and is intended to be performed in
accordance with, and only to the extent permitted by, such laws. All obligations of Guarantor hereunder are payable and performable at the place or places where the Guaranteed Obligations are payable and performable. 

Section 11.    Invalidity of Certain Provisions. 

If any provision of this Guaranty or the application thereof to any Person or circumstance shall, for any reason and to
any extent, be declared to be invalid or unenforceable, neither the remaining provisions of this Guaranty nor the application of such provision to any other Person or circumstance shall be affected thereby, and the remaining provisions of this
Guaranty, or the applicability of such provision to other Persons or circumstances, as applicable, shall remain in effect and be enforceable to the maximum extent permitted by applicable Law. 

Section 12.    Costs and Expenses of Enforcement. 

Guarantor agrees to pay to Lender on demand all costs and expenses incurred by Lender in seeking to enforce Lender’s
rights and remedies under this Guaranty, including court costs, costs of alternative dispute resolution and reasonable attorneys’ fees, whether or not suit is filed or other proceedings are initiated hereon. All such costs and expenses incurred
by Lender shall constitute a portion of the Guaranteed Obligations hereunder, shall be subject to the provisions hereof with respect to the Guaranteed Obligations and shall be payable by Guarantor on demand by Lender. 

Section 13.    No Usury. 

It is not the intention of Lender or Guarantor to obligate Guarantor to pay interest in excess of that lawfully permitted
to be paid by Guarantor under applicable Law. Should it be determined that any portion of the Guaranteed Obligations or any other amount payable by Guarantor under this Guaranty constitutes interest in excess of the maximum amount of interest that
Guarantor, in Guarantor’s capacity as guarantor, may lawfully be required to pay under applicable Law, the obligation of Guarantor to pay such interest shall automatically be limited to the payment thereof in the maximum amount so permitted
under applicable Law. The provisions of this Section shall override and control all other provisions of this Guaranty and of any other agreement between Guarantor and Lender. 

Section 14.    Representations, Warranties, and Covenants of Guarantor. 

Guarantor hereby represents, warrants, and covenants that: (a) this Guaranty is duly authorized and valid, and is
binding upon and enforceable against Guarantor; (b) Guarantor is not, and the execution, delivery and performance by Guarantor of this Guaranty will not cause Guarantor to be, in violation of or in default with respect to any law or in default
(or at risk of acceleration of indebtedness) under any agreement or restriction by which Guarantor is bound or affected; (c) unless Guarantor is a natural person, Guarantor is duly organized, validly existing, and in good standing under the
laws of the state of its organization and has full power and authority to enter into and perform this Guaranty; (d) there is no material litigation pending with respect to which process has been served or, to the knowledge of Guarantor,
threatened by or 

  
 9 








 
before any tribunal against or affecting Guarantor which, if adversely determined, would have a material adverse effect on Guarantor’s ability to perform its obligations hereunder;
(e) all financial statements and information heretofore furnished to Lender by Guarantor do, and all financial statements and information hereafter furnished to Lender by Guarantor will, fully and accurately present the condition (financial or
otherwise) of Guarantor as of their dates and the results of Guarantor’s operations for the periods therein specified, and, since the date of the most recent financial statements of Guarantor heretofore furnished to Lender, no material adverse
change has occurred in the financial condition of Guarantor, nor, except as heretofore disclosed in writing to Lender, has Guarantor incurred any material liability, direct or indirect, fixed or contingent; (f) after giving effect to this
Guaranty, Guarantor is solvent, is not engaged or about to engage in business or a transaction for which the property of Guarantor is an unreasonably small capital, and does not intend to incur or believe that it will incur debts that will be beyond
its ability to pay as such debts mature; and (g) Guarantor has read and fully understands the provisions contained in the Note, the Loan Agreement, the Security Instruments and the other Loan Documents. 

Section 15.    Notices. 

All notices, requests, consents, demands and other communications required or which any party desires to give hereunder
or under any other Loan Document shall be in writing and, unless otherwise specifically provided in such other Loan Document, shall be deemed sufficiently given or furnished if delivered by personal delivery, by nationally recognized overnight
courier service, or by certified United States mail, postage prepaid, addressed to the party to whom directed at the addresses specified in this Guaranty (unless changed by similar notice in writing given by the particular party whose address is to
be changed) or by facsimile. Any such notice or communication shall be deemed to have been given either at the time of personal delivery or, in the case of courier or mail, as of the date of first attempted delivery at the address and in the manner
provided herein, or, in the case of facsimile, upon receipt; provided that service of a notice required by any applicable statute shall be considered complete when the requirements of that statute are met. Notwithstanding the foregoing, no notice of
change of address shall be effective except upon actual receipt. This Section shall not be construed in any way to affect or impair any waiver of notice or demand provided in this Guaranty or in any other Loan Document or to require giving of notice
or demand to or upon any Person in any situation or for any reason. 

Section 16.    Cumulative Rights. 

All of the rights and remedies of Lender under this Guaranty and the other Loan Documents are cumulative of each other
and of any and all other rights at law or in equity, and the exercise by Lender of any one or more of such rights and remedies shall not preclude the simultaneous or later exercise by Lender of any or all such other rights and remedies. No single or
partial exercise of any right or remedy shall exhaust it or preclude any other or further exercise thereof, and every right and remedy may be exercised at any time and from time to time. No failure by Lender to exercise, nor delay in exercising, any
right or remedy shall operate as a waiver of such right or remedy or as a waiver of any Event of Default. No notice to or demand on Guarantor in any case shall of itself entitle Guarantor to any other or further notice or demand in similar or other
circumstances. No provision of this Guaranty or any right or remedy of 

  
 10 









 
Lender with respect hereto, or any default or breach, can be waived, nor can this Guaranty or Guarantor be released or discharged in any way or to any extent, except specifically in each case by
a writing intended for that purpose (and which refers specifically to this Guaranty) executed and delivered by Lender to Guarantor. 
 Section 17.    Term of Guaranty. 

This Guaranty shall continue in effect until all the Guaranteed Obligations and all of the obligations of Guarantor to
Lender under this Guaranty are fully and finally paid, performed and discharged and are not subject to any bankruptcy preference period or any other disgorgement. 

Notwithstanding anything stated to the contrary in this Guaranty, in the event that Lender or its nominee or any third
party takes record title to a Property of a Borrower (a “Released Borrower”) following the exercise of Lender’s rights and remedies under the Loan Documents, Guarantor shall nonetheless have the right to terminate its
continuing liability under clause (ii) of Section 1 of this Guaranty with respect to the Released Borrower’s obligations under the Environmental Agreement delivered by the Released Borrower (and only as to such obligations), upon
fulfillment of each of the following conditions to the reasonable satisfaction of Lender: 

(a)      Guarantor or the Released Borrower shall have delivered to Lender a new
environmental insurance policy which insures Lender (“New Environmental Insurance Policy”) and which: 
 (i)     is comparable to the existing Environmental Insurance Policy approved by Lender except the policy limits shall be at least $5,000,000 for each occurrence and in the
aggregate with a retention of no greater than $100,000; and 

(ii)     is issued by the same company as the existing Environmental Insurance
Policy or a replacement company with an AM Best’s Rating equivalent or better than A- (Excellent)/IX; and 
 (iii)    has a term of three (3) years from the date of issuance; and 
 (b)      Lender shall have received evidence that all premiums for three (3) years coverage under such New Environmental Insurance Policy have been prepaid in full.

 Such termination of Guarantor’s liability under clause (ii) of Section 1 of this
Guaranty with respect to a Released Borrower’s obligations under the Environmental Agreement delivered by such Released Borrower, shall become effective only upon the delivery by Lender to Guarantor of a specific written acknowledgment of the
satisfaction of all of the foregoing conditions and the termination of such obligations, which acknowledgement Lender agrees to provide unless any of the conditions to such termination have not been satisfied. This Section 17 shall under
no circumstance be interpreted to terminate or limit any of Guarantor’s liabilities in Section 1 of this Guaranty except to the extent such liabilities relate to a Released Borrower’s obligations under the Environmental
Agreement delivered by such Released Borrower, and in no event shall this Section 17 be interpreted to terminate or limit Guarantor’s liabilities in Section 1 as to any other Borrower’s obligations under the Environmental
Agreement delivered by such other Borrower unless and until the conditions of this Section 17 are satisfied as to such other 

  
 11 









 
Borrower. 
 Notwithstanding anything stated to the
contrary in this Guaranty, in the event that Borrower successfully exercises its right to terminate its continuing liability under the Environmental Agreement delivered by such Borrower pursuant to and in accordance with the terms and conditions of
Section 7 thereof, Guarantor’s liability under clause (ii) of Section 1 of this Guaranty with respect to its guaranty of such Borrower’s obligations under the Environmental Agreement delivered by such Borrower
