  Re:   Amendment No. 1 to Second Amended and Restated Revolving Credit
Agreement

Ladies and Gentlemen:
     We refer to the Second Amended and Restated Revolving Credit Agreement
dated as of December 29, 2009 (as amended 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 (collectively, the “Borrowers”), KEYBANK NATIONAL ASSOCIATION and
the other lending institutions which are parties thereto (individually, a
“Lender” and collectively, the “Lenders”), and KEYBANK NATIONAL ASSOCIATION, as
Administrative Agent for itself and each other Lender (the “Agent”). 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 the Lenders to make certain amendments to the Credit
Agreement, and you have advised us that the Lenders are prepared and would be
pleased to make the amendments so requested by us on the condition 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 May 14, 2010 (the “Amendment Date”), and subject to the
fulfillment of the conditions contained in Article II of this Amendment, the
Credit Agreement is amended in each of the following respects:
     (a) The term “Loan Documents” shall, wherever used in the Credit Agreement
or any of the other Loan Documents, be deemed to also mean and include this
Amendment.
     (b) The definition of “Libor Rate” contained in Section 1.1 of the Credit
Agreement is amended by deleting the last sentence thereof and shall read in its
entirety as follows:
     “Libor Rate. For any Libor Rate Loan for any Interest Period, the average
rates as shown in Reuters Screen LIBOR01 Page (or any successor service) at
which deposits in U.S. dollars are offered by first class banks in the London
Interbank Market at approximately 11:00 a.m. (London time) on the day that is
two (2) Libor Business Days prior to the first day of such Interest Period with
a maturity approximately equal to such Interest Period and in an amount
approximately equal to the amount to which such Interest Period relates,
adjusted for reserves and taxes if required by future regulations. If Reuters no
longer reports such rate or Agent determines in good faith that the rate so
reported no longer accurately reflects the rate available to Agent in the London
Interbank Market, then any and all outstanding Loans shall be Base Rate Loans
and bear interest at the Base Rate plus the Applicable Base Rate Margin. For any
period during which a Reserve Percentage shall apply, the Libor Rate with
respect to Libor Rate Loans shall be equal to the amount determined above
divided by an amount equal to 1 minus the Reserve Percentage.”
     (c) The definition of “Unhedged Loans” is hereby deleted in its entirety.
     (d) Section 10.1 is hereby amended to read in its entirety as follows:
     “At all times, (i) from the Closing Date through the fiscal quarter ending
September 30, 2010, Consolidated Total Indebtedness shall not exceed sixty-five
percent (65%) of Consolidated Gross Asset Value, (ii) from the fiscal quarter
ending December 31, 2010 through the fiscal quarter ending September 30, 2011,
Consolidated Total Indebtedness shall not exceed sixty-two and one half of one
percent (62.5%) of Consolidated Gross Asset Value, and (iii) during each fiscal
quarter ending on or after December 31, 2011, Consolidated Total Indebtedness

2

--------------------------------------------------------------------------------

 

shall not exceed sixty percent (60%) of Consolidated Gross Asset Value. This
covenant shall be tested quarterly as of the last day of the applicable
quarter.”
     (e) Section 10.2 is hereby amended by deleting the following phrase at the
beginning thereof, “As at the end of any fiscal quarter” and substituting the
following in lieu thereof: “At all times, as tested at the end of each fiscal
quarter,”.
     (f) Section 10.3 is hereby amended by deleting the following phrase at the
beginning thereof, “As at the end of any fiscal quarter” and substituting the
following in lieu thereof: “At all times, as tested at the end of each fiscal
quarter,”.
     (g) Section 10.4 is hereby amended by deleting the following phrase at the
beginning thereof, “As at the end of any fiscal quarter or any other date of
measurement” and substituting the following in lieu thereof: “At all times, as
tested at the end of each fiscal quarter and any other date of measurement,”.
     (h) Section 10.5 is hereby amended by deleting the following phrase at the
beginning thereof, “As at the end of any fiscal quarter or any other date of
measurement” and substituting the following in lieu thereof: “At all times, as
tested at the end of each fiscal quarter and any other date of measurement,”.
     (i) Section 10.6 is hereby amended by deleting the following phrase at the
beginning thereof, “As of the end of any fiscal quarter” and substituting the
following in lieu thereof: “At all times, as tested at the end of each fiscal
quarter,”.
ARTICLE II

Amendment Date is subject to the fulfillment to the satisfaction of the Lenders

the ratable benefit of each of the Lenders (based upon their respective
Commitment Percentage), along with, to the Agent, all other fees associated with

ARTICLE III

     (b) No Defaults or Events of Default. No Default or Event of Default exists
on the Amendment Date, and no condition exists on the date hereof which would,
with notice or the lapse of time, or both, constitute a Default or an Event of
Default under the Credit Agreement.
     (c) Binding Effect of Documents. This Amendment and each of the Joinder
Agreements, as applicable, has been duly authorized, executed and delivered to
you by each of the Borrowers and the Guarantor and is in full force and effect

Borrowers and the Guarantor contained herein and therein constitute the legal,
valid and binding obligations of such Borrower and Guarantor enforceable against
such Borrower and Guarantor in accordance with their respective terms.
ARTICLE IV
MISCELLANEOUS
     This Amendment may be executed in any number of counterparts, each of which
when executed and delivered shall be deemed an original, but all of which
together shall constitute one instrument. In making proof of this Amendment, it
shall not be necessary to produce or account for more than one counterpart
thereof signed by each of the parties hereto. Except to the extent specifically
amended and supplemented hereby, all of the terms, conditions and the provisions
of the Credit Agreement and each of the other Loan Documents shall otherwise
remain unmodified, and the Credit Agreement and each of the

4

--------------------------------------------------------------------------------

 

other Loan Documents, as amended and supplemented by this Amendment, are
confirmed as being in full force and effect, and each of the Borrowers and the
Guarantor hereby ratifies and confirms all of its agreements and obligations
