 Re: Amendment No. 3 to Term Loan Agreement and Consent 

Ladies and Gentlemen: 
 We refer
to the Term Loan Agreement dated as of July 18, 2011 (as amended, restated, modified, renewed, supplemented and in effect from time to time, the “Credit Agreement”), by and among FIRST POTOMAC REALTY INVESTMENT LIMITED
PARTNERSHIP, a Delaware limited partnership, and certain of its Wholly-Owned Subsidiaries and other Subsidiaries (collectively, the “Borrowers”), KEYBANK NATIONAL ASSOCIATION and the other lending institutions which are parties
thereto (individually, a “Lender” and collectively, the “Lenders”), KEYBANK NATIONAL ASSOCIATION, as administrative agent for itself and each other Lender (the “Agent”) and certain other parties.
Capitalized terms used in this letter of agreement (this “Amendment”) which are not defined herein, but which are defined in the Credit Agreement, shall have the same meanings herein as therein, as the context so requires.

 We have requested that the Lenders: (1) amend the Credit Agreement to, among other things, (a) modify the covenant
relating to the ratio of Consolidated Total Indebtedness to Consolidated Gross Asset Value set forth in §10.1, (b) modify the covenant relating to Consolidated Debt Yield set forth in §10.2, (c) modify the covenant relating to
Consolidated Tangible Net Worth set forth in §10.4, and (d) modify the covenant relating to the ratio of Consolidated Total Indebtedness to the Value of Unencumbered Properties set forth in §10.5, and (2) consent under
§9.4(b) of the Credit Agreement to the exclusion of the Permanent Disposition (as hereinafter defined) of the Real Estate Assets comprising the Industrial Portfolio (as hereinafter defined) from the calculation of net sales price of Real Estate
Assets and other property sold, transferred or otherwise disposed of in any four-quarter period for the purposes of the twenty percent (20%) threshold set forth in said §9.4(b) for the sale, transfer and disposition of Real Estate Assets
and other property; and you have advised us that the Lenders are prepared to make the amendments and provide the consent as set forth herein, including to reflect the foregoing as requested by us, on the terms and conditions set forth herein,
including, without limitation, that we join in this Amendment. Accordingly, in consideration of these premises, the promises, mutual covenants and agreements contained in this Amendment, and fully intending to be legally bound by this Amendment, we
hereby agree as follows: 

 ARTICLE I 
 AMENDMENTS TO CREDIT AGREEMENT 
 Effective as of February 8, 2013 (the
“Amendment No. 3 Effective Date”), and subject to the fulfillment of the conditions contained in Article III of this Amendment, the Credit Agreement is hereby amended in each of the following respects:

the Agent and the Lenders.

 “Net Sales Proceeds. The aggregate cash proceeds received by the Borrower, any
Subsidiary or any Partially-Owned Entity in connection with the consummation of any Permanent Disposition net of the following costs and expenses, as evidenced by invoices or other evidence reasonably acceptable to Agent: (a) all reasonable and
customary out-of-pocket costs paid or payable by such Borrower, Subsidiary or Partially-Owned Entity in connection with such Permanent Disposition (including, without limitation, legal, accounting and investment banking fees, sales commissions and
taxes), and (b) for Permanent Dispositions involving the sale of any Real Estate Asset that is encumbered by Indebtedness, the repayment of such Indebtedness, including, without limitation, prepayment fees and yield maintenance charges.”

 (d) The following new definition is inserted after the definition of “PBGC” and before the definition of
“Permits”:

sale or assignment of the entire fee simple or leasehold interest in such Real Estate Asset, as applicable.” 

  
 2 

 (e) The definition of “Unsecured Consolidated Total Indebtedness” is amended by
inserting at the end thereof the following new sentence: “Notwithstanding the foregoing, Unsecured Consolidated Total Indebtedness shall include Recourse Indebtedness that is secured solely by partnership or other ownership interests in
any Subsidiary or Partially-Owned Entity that owns a Real Estate Asset that is encumbered by a mortgage securing Indebtedness, provided, however, the 2007 Term Loan shall be excluded from Unsecured Consolidated Total
Indebtedness except if the outstanding principal amount thereof at any date of determination exceeds $10,000,000, in which case, the principal amount thereof in excess of $10,000,000 shall be included in Unsecured Consolidated Total Indebtedness. In
no event shall any Indebtedness under that certain Secured Term Loan Agreement dated as of February 8, 2013 (the “2013 Term Loan Agreement”) among certain Subsidiaries of FPLP, KeyBank National Association, individually and as
administrative agent, and certain other lenders be included in Unsecured Consolidated Total Indebtedness unless, and then only to the extent that, the principal amount of such Indebtedness is increased above the Total Commitment (as defined in the
2013 Term Loan Agreement) on the date of this Agreement.” 
 2. Title to Properties; Leases; Eligible Unencumbered

the dollar amount used in clause (i) above for the purpose of calculating the sum set forth in this Section 10.4 for each date of determination shall reduce by an amount equal to sixty-five percent (65%) of the Net Sales Proceeds of
the Permanent Disposition of any of the Real Estate Assets included in the Industrial Portfolio, which Real Estate Assets and the respective direct and indirect owners thereof are listed on Schedule 10.4 hereto, provided that, for each such
Permanent Disposition, such reduction shall not apply unless and until (y) Agent shall have received evidence satisfactory to Agent of such Permanent Disposition and of the amount of the Net Sales Proceeds therefrom, which Agent shall endeavor
to approve or disapprove, and shall provide any reasons for disapproval with reasonable specificity, in writing via electronic mail transmission to the Chief Financial Officer, Chief Accounting Officer and Director, Finance & Treasury of
the Trust (at ablocher@first-potomac.com, mcomer@first-potomac.com, and ttillman@first-potomac.com, or such other electronic mail addresses of which the Borrower shall give Agent prior written notice) no later than ten
(10) business days following receipt of such evidence from the Borrower, and (z) in the case of such Permanent Disposition of any Real Estate Asset which is in the Unencumbered Pool, such Real Estate Asset shall have been duly released
from the Unencumbered Pool in accordance with the terms hereof.” 
 7. Unencumbered Pool Leverage. §10.5 is
deleted in its entirety and the following is substituted in lieu thereof: 
 “§10.5 Unencumbered Pool Leverage.
At all times, as tested at the end of each fiscal quarter and any other date of measurement, (i) for each fiscal quarter ending on or after December 31, 2012 through the fiscal quarter ending September 30, 2013, Unsecured Consolidated
Total Indebtedness shall not exceed sixty-five percent (65%) of the aggregate Value of Unencumbered Properties on the last day of such fiscal quarter, and (ii) for each fiscal quarter ending on or after December 31, 2013, Unsecured
Consolidated Total Indebtedness shall not exceed sixty percent (60%) of the aggregate Value of Unencumbered Properties on the last day of such fiscal quarter. For purposes of the covenant set forth in this §10.5, any New Debt incurred by
the Borrower after the date hereof shall be deemed to be Unsecured Consolidated Total Indebtedness.” 

  
 4 

 8. Schedules. 

(a) The existing Schedules 1, 7.1(b), 7.3(c), 7.3(d), 7.13, and 7.19 to the Credit Agreement are deleted in their entirety and the updated
Schedules 1, 7.1(b), 7.3(c), 7.3(d), 7.13, and 7.19 attached hereto are substituted in lieu thereof. 
 (b) The new Schedule 10.4
attached hereto is attached to the Credit Agreement and made a part thereof. 
 ARTICLE II 

CONSENT TO EXCLUSION OF INDUSTRIAL PORTFOLIO 
 The Borrower intends to consummate the Permanent Disposition, in a four-quarter period, of the Industrial Portfolio and of certain other Real Estate Assets (the “Other Sale Properties”).
The aggregate sales price (net of (i) any Indebtedness secured by a Lien on such Real Estate Assets or other property, if any, and (ii) the purchase price of any Real Estate Assets or other property acquired during such four-quarter
period, minus closing costs and any Indebtedness secured by a Lien on such acquired Real Estate Assets or other property) (the “Net Sales Price”) of the Permanent Disposition of the Industrial Portfolio and the Other Sale Properties
could exceed twenty percent (20%) of the most recently reported Consolidated Gross Asset Value. Accordingly, Borrower has requested that the Lenders consent, and, subject to Article III hereof, the Lenders do consent, to the Borrower’s
exclusion of the Permanent Disposition of the Industrial Portfolio (or any individual Real Estate Asset contained therein) from the calculation of the Net Sales Price that is subject to the twenty percent (20%) threshold set forth in
§9.4(b) with respect to the Sale (as defined in §9.4(b)) of Real Estate Assets or other property, provided that, for any period of time during which Borrower excludes the Permanent Disposition of the Industrial Portfolio (or any individual
Real Estate Asset contained therein) from such calculation, Borrower agrees that the Net Sales Price of the Sale of the Other Sale Properties and any other property shall not exceed ten percent (10%), rather than twenty percent (20%), of the most
recently reported Consolidated Gross Asset Value. For the avoidance of doubt, the consent provided under this Article II shall apply only with respect to the twenty percent (20%) threshold set forth in the first sentence of §9.4(b) for the
Sale of Real Estate Assets or other property and not with respect to any other threshold set forth in said §9.4(b) (including the twenty percent (20%) threshold with respect to Indebtedness Liens or the two percent (2%) threshold
requiring the provision of a compliance certificate with respect to any Sale or Indebtedness Lien). 
 ARTICLE III

otherwise affect any rights or remedies of Agent or any Lender with respect to Borrower’s obligations to comply with the covenants as set forth in the Credit Agreement (after giving effect to this Amendment);

 “(ss) “SSF Grandfathered Percentage” shall mean, with respect to

Company after the date of this Amendment, the February 2013 Offering Investor Grandfathered Percentage shall, subsequent to such sale, transfer or disposition, mean, with respect to such February 2013 Offering Grandfathered Investor, the lesser of
(i) the February 2013 Offering Investor Grandfathered Percentage as in effect immediately prior to such sale, transfer or disposition or (ii) the percentage of outstanding shares of Common Stock of the Company that such February 2013

Investor and shall be subject to all of the provisions of this Agreement in the same manner as any Person who is not and was not a February 2013 Offering Grandfathered Investor.” 

3. The definition of “Acquiring Person” in Section 1(a) of the Rights Agreement is hereby amended and restated in
its entirety to read as follows: 
 ““Acquiring Person” shall mean any Person (as such term is hereinafter
defined) who or which, together with all Affiliates (as such term is hereinafter defined) and Associates (as such term is hereinafter defined) of such Person, shall be the Beneficial Owner (as such term is hereinafter defined) of 15% or more of the
shares of Common Stock of the Company then outstanding, but shall not include (i) the Company, (ii) any Subsidiary (as such term is hereinafter defined) of the Company, (iii) any employee benefit plan or compensation arrangement of
the Company or any Subsidiary of the Company or (iv) any Person holding shares of Common Stock of the Company organized, appointed or established by the Company or any Subsidiary of the Company for or pursuant to the terms of any such employee
benefit plan or compensation arrangement (the Persons described in clauses (i) through (iv) above are referred to herein as “Exempt Persons”); provided, however, that the term “Acquiring Person”
shall not include any Grandfathered Person, any INTER RAO Grandfathered Person, any SSF Grandfathered Person or any February 2013 Offering Grandfathered Investor, unless (A) with respect to a Grandfathered Person, such Grandfathered Person
becomes the Beneficial Owner of a percentage of the shares of Common Stock of the Company then outstanding equal to or exceeding the Grandfathered Percentage of such Grandfathered Person, (B) with respect to an

  
 3 

 
INTER RAO Grandfathered Person, such INTER RAO Grandfathered Person becomes the Beneficial Owner of a percentage of the shares of Common Stock of the Company then outstanding equal to or
exceeding the INTER RAO Grandfathered Percentage of such INTER RAO Grandfathered Person, (C) with respect to an SSF Grandfathered Person, such SSF Grandfathered Person becomes the Beneficial Owner of a percentage of the shares of Common Stock
of the Company then outstanding equal to or exceeding the SSF Grandfathered Percentage of such SSF Grandfathered Person, and (D) with respect to a February 2013 Offering Grandfathered Investor, such February 2013 Offering Grandfathered Investor
becomes the Beneficial Owner of a percentage of the shares of Common Stock of the Company then outstanding equal to or exceeding the February 2013 Offering Investor Grandfathered Percentage of such February 2013 Offering Grandfathered Investor.

 Notwithstanding the foregoing, no Person shall become an “Acquiring Person” as the result of an acquisition by the
Company of Common Stock of the Company which, by reducing the number of shares outstanding, increases the proportionate number of shares Beneficially Owned by such Person to 15% (or in the case of a Grandfathered Person, INTER RAO Grandfathered
Person, SSF Grandfathered Person or February 2013 Offering Grandfathered Investor, the Grandfathered Percentage, INTER RAO Grandfathered Percentage, SSF Grandfathered Percentage or February 2013 Offering Investor Grandfathered Percentage applicable
to such Person) or more of the shares of Common Stock of the Company then outstanding; provided, however, that if a Person shall become the Beneficial Owner of 15% (or in the case of a Grandfathered Person, INTER RAO Grandfathered Person, SSF
Grandfathered Person or February 2013 Offering Grandfathered Investor, the Grandfathered Percentage, INTER RAO Grandfathered Percentage, SSF Grandfathered Percentage or February 2013 Offering Investor Grandfathered Percentage applicable to such
Person) or more of the shares of Common Stock of the Company then outstanding by reason of share purchases by the Company and shall, after such share purchases by the Company, become the Beneficial Owner of any additional shares (other than pursuant
to a stock split, stock dividend or similar transaction) of Common Stock of the Company and immediately thereafter be the Beneficial Owner of 15% (or in the case of a Grandfathered Person, INTER RAO Grandfathered Person, SSF Grandfathered Person or
February 2013 Offering Grandfathered Investor, the Grandfathered Percentage, INTER RAO Grandfathered Percentage, SSF Grandfathered Percentage or February 2013 Offering Investor Grandfathered Percentage applicable to such Person) or more of the
shares of Common Stock of the Company then outstanding, then such Person shall be deemed to be an “Acquiring Person.” 

In addition, notwithstanding the foregoing, and notwithstanding anything to the contrary provided in the Agreement including without
limitation in Sections 1(kk), 3(a) or 27, a Person shall not be an “Acquiring Person” if the Board of Directors of the Company determines at any time that a Person who would otherwise be an “Acquiring Person,” has become such
without intending to become an “Acquiring Person,” and such Person divests as promptly as practicable (or within such period of time as the Board of Directors of the Company determines is reasonable) a sufficient number of shares of Common
Stock of the Company so that such Person would no 

  
 4 

 
longer be an “Acquiring Person,” as defined pursuant to the foregoing provisions of this Section 1(a).” 

4. Section 3(a) of the Rights Agreement is hereby amended and restated in its entirety to read as follows: 

“From the date hereof until the earlier of (i) the Close of Business on the tenth calendar day after the Stock Acquisition Date
or (ii) the Close of Business on the tenth Business Day (or such later calendar day, if any, as the Board of Directors of the Company may determine in its sole discretion) after the date a tender or exchange offer by any Person, other than an
Exempt Person, is first published or sent or given within the meaning of Rule 14d-4(a) of the Exchange Act, or any successor rule, if, upon consummation thereof, such Person could become the Beneficial Owner of 15% (or in the case of a Grandfathered
Person, INTER RAO Grandfathered Person, SSF Grandfathered Person or February 2013 Offering Grandfathered Investor, the Grandfathered Percentage, INTER RAO Grandfathered Percentage, SSF Grandfathered Percentage or February 2013 Offering Investor
Grandfathered Percentage applicable to such Person) or more of the shares of Common Stock of the Company then outstanding (including any such date which is after the date of this Agreement and prior to the issuance of the Rights) (the earliest of
such dates being herein referred to as the “Distribution Date”), (x) the Rights will be evidenced (subject to the provisions of Section 3(b) hereof) by the certificates for the Common Stock of the Company registered in the
names of the holders of the Common Stock of the Company (which certificates for Common Stock of the Company shall be deemed also to be certificates for Rights) and not by separate certificates, and (y) the Rights will be transferable only in
connection with the transfer of the underlying shares of Common Stock of the Company. Upon the Distribution Date, the Company shall send written notice to Rights Agent, and the Rights Agent will, as soon as practicable after receipt of such notice,
at the Company’s expense send, by first-class, insured, postage prepaid mail, to each record holder of the Common Stock of the Company as of the Close of Business on the Distribution Date, at the address of such holder shown on the records of
the Company, one or more certificates, in substantially the form of Exhibit B hereto (the “Right Certificates”), evidencing one Right for each share of Common Stock of the Company so held, subject to adjustment as provided
herein. In the event that an adjustment in the number of Rights per share of Common Stock of the Company has been made pursuant to Section 11(o) hereof, the Company may make the necessary and appropriate rounding adjustments (in accordance with
Section 14(a) hereof) at the time of distribution of the Right Certificates, so that Right Certificates representing only whole numbers of Rights are distributed and cash is paid in lieu of any fractional Rights. As of and after the Close of
Business on the Distribution Date, the Rights will be evidenced solely by such Right Certificates.” 
 5. Except as
expressly set forth herein, this Amendment shall not by implication or otherwise alter, modify, amend or in any way affect any of the terms, conditions, obligations, covenants or agreements contained in the Rights Agreement, all of which are
ratified and affirmed in all respects and shall continue in full force and effect and shall be otherwise unaffected.

 6. This Amendment shall be governed by and construed in accordance with the laws of the
State of Delaware, United States of America, applicable to contracts made and to be performed entirely within such State, without regard to conflict-of-law principles. 
 7. This Amendment may be executed in any number of counterparts and each of such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but
one and the same instrument. A signature to this Amendment transmitted electronically shall have the same authority, effect, and enforceability as an original signature.
