NOW, THEREFORE, for good and valuable consideration, the receipt and adequacy of
which is hereby acknowledged, the parties hereto hereby agree as follows:

1.
Definitions. All capitalized undefined terms used in this Third Amendment shall
have the meanings ascribed thereto in the Credit Agreement, as amended hereby.

2.
Amendments to Credit Agreement. Effective as set forth in Section 3 below, the
Credit Agreement is hereby amended as follows:

a.
Section 1.1 of the Credit Agreement is hereby amended to add the following new
definition in the appropriate alphabetical order:

“Third Amendment Effective Date” means March 17, 2017.
b.
The following definitions appearing in Section 1.1 of the Credit Agreement are
hereby amended and restated in their entirety as follows:

“Interest Expense” means, for any period, without duplication, (a) total
interest expense of the Parent, including capitalized interest not funded under
a construction loan interest reserve account but excluding any non-cash interest
charges to the extent accruing as the result of hedge ineffectiveness under
GAAP, determined on a consolidated basis in accordance with GAAP for such
period, plus (b) the Parent’s Ownership Share of Interest Expense of
Unconsolidated Affiliates for such period.
“Total Asset Value” means, at a given time, the sum (without duplication) of all
of the following of the Parent and its Subsidiaries determined on a consolidated
basis in accordance with GAAP applied on a consistent basis: (a) cash and Cash
Equivalents (other than tenant deposits and other cash and Cash Equivalents that
are subject to a Lien or a Negative Pledge or the disposition of which is
restricted in any way); plus (b) with respect to all Properties owned (or leased
pursuant to a Ground Lease) by the Borrower or any Subsidiary for the 12-month
period ending on such date of determination, the quotient of (i) Net Operating
Income of the Parent and its Subsidiaries for such 12-month period, divided by
(ii) the Capitalization Rate; plus (c) with respect to any Property acquired

Development Properties; plus (e) the acquisition price of Unimproved Land, less
any GAAP impairment charges specific to any such asset; plus (f) the acquisition
price of all mortgage notes receivable and mezzanine loans, less any GAAP

assets held by Unconsolidated Affiliates (excluding assets of the type described
in the immediately preceding clause (a)) will be included in the calculation of
Total Asset Value consistent with the above described treatment for wholly owned
assets. For purposes of determining Total Asset Value, Properties which are not
valued under subsections (c), (d), or (e), of this definition above, and which
either have an Occupancy Rate of less than 85% as of the applicable date of
determination or shall have had an Occupancy Rate of 85% or more for less than
two (2) consecutive fiscal quarters during the six (6) consecutive fiscal
quarter period ending on such date of determination, shall be valued at the
greater of (i) gross book value (undepreciated) reported for GAAP purposes and
(ii) the capitalized value obtained under subsection (b) of this definition
above, provided, however, that any such Property (x) may only be included in the
calculation of Total Asset Value with a valuation calculated pursuant to this
clause for a maximum of six (6) consecutive fiscal quarters (and thereafter any
such Property shall be valued in accordance with subsection (b) above), and (y)
may not be included in the calculation of Total Asset Value with a valuation
calculated pursuant to this clause if such Property has already been valued
pursuant to this clause and subsequently valued in any other manner.
Notwithstanding the foregoing, for purposes of determining Total Asset Value, to
the extent the amount of Total Asset Value attributable to (A) Properties leased
under Ground Leases would exceed 20% of Total Asset Value, such excess shall be
excluded, (B) Properties subject to adjustment above for having an Occupancy
Rate of less than 85% would exceed

-2-

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

25% of Total Asset Value, such excess shall be excluded, (C) assets of the type
described in the foregoing clauses (d), (e), (f) and the Borrower’s Ownership
Share of assets held by Unconsolidated Affiliates would exceed, in the
aggregate, 30% of Total Asset Value, such excess shall be excluded and (D)
Development Properties would exceed 10% of Total Asset Value, such excess shall
be excluded.
“Unencumbered Asset Value” means, at a given time, the sum (without duplication)
of all of the following of the Parent and its Subsidiaries determined on a
consolidated basis in accordance with GAAP applied on a consistent basis: (a)
with respect to all Unencumbered Pool Properties owned (or leased pursuant to a
Ground Lease) by the Borrower or any Subsidiary for the 12-month period ending
on such date of determination, the quotient of (i) Unencumbered NOI (excluding
NOI attributable to Development Properties) for the 12-month period ending on
such date of determination divided by (ii) the Capitalization Rate, plus (b)
with respect to any Unencumbered Pool Property acquired during the 12-month
period ending on such date of determination, the acquisition price paid for all
such Unencumbered Pool Properties plus (c) the GAAP book value of all
Unencumbered Development Properties. Notwithstanding the foregoing, for purposes
of determining Unencumbered Asset Value, to the extent the amount of
Unencumbered Asset Value attributable to (A) Unencumbered Pool Properties leased
under Ground Leases would exceed 10% of Unencumbered Asset Value, such excess
shall be excluded and (B) Unencumbered Development Properties would exceed 15%
of Unencumbered Asset Value, such excess shall be excluded.
“Unsecured Interest Expense” means, with respect to a Person and for any period,
all Interest Expense of such Person for such period attributable to Unsecured
Indebtedness of such Person.
c.
Section 1.1 of the Credit Agreement is hereby amended to add the following new
definition in the appropriate alphabetical order:

“Unencumbered Development Property” means any Development Property (or any
Property that shall have (a) previously been a Development Property, (b) had (i)
an Occupancy Rate of less than 85% as of the applicable date of determination or
(ii) an Occupancy Rate of 85% or more for less than two (2) consecutive fiscal
quarters during the six (6) consecutive fiscal quarter period ending on such
date of determination and (c) been valued on a gross book value basis for
purposes of calculating Total Asset Value as of the applicable date of
determination) that satisfies all of the following requirements as confirmed by
the Administrative Agent: (w) such Development Property is owned in fee simple,
or leased under a Ground Lease, by the Borrower or a Guarantor; (x) such
Development Property is located in a State of the United States of America or in
the District of Columbia; (y) regardless of whether such Development Property is
owned by the Borrower or a Subsidiary, the Borrower has the right directly, or
indirectly through a Subsidiary, to take the following actions without the need
to obtain the consent of any Person: (i) to create Liens on such Development
Property as security for Indebtedness of the Borrower or such Subsidiary, as
applicable, and (ii) to sell, transfer or otherwise dispose of such Development
Property; and (z) neither such Development Property, nor if such Development
Property is owned by a Subsidiary, any of the Borrower’s

-3-

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

direct or indirect ownership interest in such Subsidiary, is subject to (i) any
Lien other than Permitted Liens or (ii) any Negative Pledge.
d.
Section 10.1(a) of the Credit Agreement is hereby amended (i) to replace
“$1,053,000,000” appearing therein with “$909,185,575” and (ii) to replace
