 3. Purchase, Sale and Delivery of Offered Securities. On the basis
of the representations, warranties and agreements and subject to the terms and conditions set forth herein, each of the Company and the Selling Shareholder agrees, severally and not jointly, to sell to the several Underwriters, and each of the
Underwriters agrees, severally and not jointly, to purchase from the Company and the Selling Shareholder, at a purchase price of $14.88 per ADS (representing the initial public offering price less underwriting commissions and concessions), the
respective number of Firm Securities set forth opposite the names of the Underwriters in Schedule A hereto, plus any additional number of Firm Securities which such Underwriter may become obligated to purchase pursuant to the provisions of
Section 10 hereof (rounded up or down at the discretion of the Representatives to avoid fractions). 
  

 22 

 Executed transfer forms for the Offered Shares represented by the Offered Securities to be sold by the
Selling Shareholder hereunder have been placed in custody, for delivery under this Agreement, under a Custody Agreements made with the Company, as the Custodian. The Selling Shareholder agrees that the Offered Shares represented by the transfer
forms held in custody for the Selling Shareholder under such Custody Agreements are subject to the interests of the Underwriters hereunder, that the arrangements made by the Selling Shareholder for such custody are to that extent irrevocable, and
that the obligations of the Selling Shareholder hereunder shall not be terminated by operation of law or the occurrence of any other event. 
 The Company and the Custodian will deliver the Firm Securities to or as instructed by the Representatives for the accounts of the several Underwriters through the facilities of DTC in a form reasonably acceptable to the Representatives
against payment of the purchase price by the Underwriters in Federal (same day) funds by wire transfer to an account at a bank acceptable to the Representatives drawn to the order of the Company (for itself and as Custodian for the Selling
Shareholder) at 9:00 a.m., U.S. Eastern time, on April 7, 2009, or at such other time not later than seven full business days thereafter as the Representatives and the Company determine, such time being herein referred to as the “First
Closing Date.” For purposes of Rule 15c6-1 under the Exchange Act, the First Closing Date (if later than the otherwise applicable settlement date) shall be the settlement date for payment of funds and delivery of securities for all the
Firm Securities sold pursuant to the offering. The Firm Securities so to be delivered or evidence of their issuance will be made available for checking at the office of Davis Polk & Wardwell at 18/F, the Hong Kong Club Building, 3A Chater
Road, Central, Hong Kong, at least 24 hours prior to the First Closing Date. 
 In addition, upon written notice from the Representatives
given to the Custodian from time to time not more than 30 days subsequent to the date of the Final Prospectus, the Underwriters may purchase all or less than all of the Optional Securities at the same purchase price per ADS to be paid for the Firm
Securities. The Selling Shareholder agrees to sell to the Underwriters the number of Optional Securities specified in such notice and the Underwriters agree, severally and not jointly, to purchase such Optional Securities. Such Optional Securities
shall be purchased for the account of each Underwriter in the same proportion as the number of Firm Securities set forth opposite such Underwriter’s name bears to the total number of Firm Securities (subject to adjustment by the Representatives
to eliminate fractions) and may be purchased by the Underwriters only for the purpose of covering over-allotments made in connection with the sale of the Firm Securities. No Optional Securities shall be sold or delivered unless the Firm Securities
previously have been, or simultaneously are, sold and delivered. The right to purchase the Optional Securities or any portion thereof may be exercised from time to time and to the extent not previously exercised may be surrendered and terminated at
any time upon notice by the Representatives to the Custodian. 
 Each time for the delivery of and payment for the Optional Securities, being
herein referred to as an “Optional Closing Date,” which may be the First Closing Date (the First Closing Date and each Optional Closing Date, if any, being sometimes referred to as a “Closing Date”), shall be
determined by the Representatives but shall be not later than five full business days after written notice of election to purchase Optional Securities is given. The Company will deliver the Optional Securities being purchased on each Optional
Closing Date to or as instructed by the Representatives for the accounts of the several Underwriters in a form reasonably acceptable to the Representatives against payment of the purchase price therefor in Federal (same day) funds by wire transfer
to an account at a bank acceptable to the Representatives drawn to the order of the Company, as Custodian of the Selling Shareholder. The Optional Securities being purchased on each Optional Closing Date or evidence of their issuance will be made
available for checking at the above office of Davis Polk & Wardwell at a reasonable time in advance of such Optional Closing Date.

 5. Certain Agreements of the Company, the Selling Shareholder and Sohu. 
 (A) The Company agrees with the several Underwriters that: 
 (a) Additional Filings. Unless filed pursuant to Rule 462(c) as part of the Additional Registration Statement in accordance with the next sentence, the Company will file the Final Prospectus, in a form
approved by the Representatives, with the Commission pursuant to and in accordance with subparagraph (1) (or, if applicable and if consented to by the Representatives, subparagraph (4)) of Rule 424(b) not later than the earlier of
(A) the second business day following the execution and delivery of this Agreement or (B) the fifteenth business day after the Effective Time of the Initial Registration Statement. The Company will advise the Representatives promptly of
any such filing pursuant to Rule 424(b) and provide satisfactory evidence to the Representatives of such timely filing. If an Additional Registration Statement is necessary to register a portion of the Offered Securities under the Act but the
Effective Time thereof has not occurred as of the execution and delivery of this Agreement, the Company will file the Additional Registration Statement or, if filed, will file a post-effective amendment thereto with the Commission pursuant to and in
accordance with Rule 462(b) on or prior to 10:00 p.m., U.S. Eastern time, on the date of this Agreement or, if earlier, on or prior to the time the Final Prospectus is finalized and distributed to any Underwriter, or will make such filing at
such later date as shall have been consented to by the Representatives. 
 (b) Filing of Amendments; Response to Commission
Requests. The Company will promptly advise the Representatives of any proposal to amend or supplement at any time the Initial Registration Statement, any Additional Registration Statement or any Statutory Prospectus and will not effect such
amendment or supplementation without the Representatives’ consent; and the Company will also advise the Representatives promptly of (i) the effectiveness of any Additional Registration Statement (if its Effective Time is subsequent to the
execution and delivery of this Agreement), (ii) any amendment or supplementation of a Registration Statement or any Statutory Prospectus, (iii) any request by the Commission or its staff for any amendment to any Registration Statement, for
any supplement to any Statutory Prospectus or for any additional information, (iv) the institution by the Commission of any stop order proceedings in respect of a Registration Statement or the threatening of any proceeding for that purpose, and
(v) the receipt by the Company of any notification with respect to the suspension of the qualification of the Offered Securities in any jurisdiction or the institution or threatening of any proceedings for such purpose. The Company will use its
best efforts to prevent the issuance of any such stop order or the suspension of any such qualification and, if issued, to obtain as soon as possible the withdrawal thereof. 
 (c) Continued Compliance with Securities Laws. If, at any time when a prospectus relating to the Offered Securities is (or but for
the exemption in Rule 172 would be) required to be delivered under the Act by any Underwriter or dealer, any event occurs as a result of which the Final Prospectus as then amended or supplemented would include an untrue statement of a material
fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Registration Statement or supplement the
Final Prospectus to comply with the Act, the Company will promptly notify the Representatives of such event and will promptly prepare and file with the Commission and furnish, at its own expense, to the Underwriters and the dealers and any other
dealers upon request of the Representatives, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance. Neither the Representatives’ consent to, nor the Underwriters’
delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 7 hereof.

Effective Time of the Additional Registration Statement) which will satisfy the provisions of Section 11(a) of the Act and Rule 158 under the Act. For the purpose of the preceding sentence, “Availability Date” means the
45th day after the end of the fourth fiscal quarter following the fiscal quarter that includes such Effective Time, except that, if such fourth fiscal quarter is the last quarter of the Company’s fiscal year, “Availability
Date” means the 90th day after the end of such fourth fiscal quarter.

Company will furnish to the Representatives copies of each Registration Statement (four of which will be signed and will include all exhibits), each related Statutory Prospectus, and, so long as a prospectus relating to the Offered Securities is (or
but for the exemption in Rule 172 would be) required to be delivered under the Act, the Final Prospectus and all amendments and supplements to such documents, in each case in such quantities as the Representatives request. The Final Prospectus
shall be so furnished on or prior to 3:00 p.m., U.S. Eastern time, on the second business day following the execution and delivery of this Agreement. All other documents shall be so furnished as soon as available. The Company will pay the
expenses of printing and distributing to the Underwriters all such documents.

furnish such reports or statements to the Underwriters.

Stabilization. Neither the Company nor any director, officer, agent, employee, affiliate or person acting on its behalf will take, directly or indirectly, any action designed, or which will constitute or might reasonably be expected to cause or
result in, under the Exchange Act or otherwise, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Offered Securities. 
 (k) Taxes. The Company will indemnify and hold harmless the Underwriters against any documentary, stamp or similar issue tax,
including any interest and penalties, on the creation, issue and sale of the Offered Securities and on the execution and delivery of the Transaction Documents. All payments to be made by the Company hereunder shall be made without withholding or
deduction for or on account of any present or future taxes, duties or governmental charges whatsoever unless the Company is compelled by law to deduct or withhold such taxes, duties or charges. In that event, the Company shall pay such additional
amounts as may be necessary in order that the net amounts received after such withholding or deduction shall equal the amounts that would have been received if no withholding or deduction had been made. 
 (l) Restriction on Sale of Securities. For the period specified below (the “Lock-Up Period”), the Company will

to the date on which the distribution of the Offered Securities as contemplated herein and in the General Disclosure Package and Final Prospectus has been completed, as determined by the Representatives, the Selling Shareholder or Sohu has knowledge
of the occurrence of any event relating to the Selling Shareholder or Sohu as a result of which the Final Prospectus or the Registration Statement, in each case as then amended or supplemented, would include an untrue statement of a material fact or
omit to state any material fact necessary to make the statements therein (except in the case of the Registration Statement), in the light of the circumstances under which they were made, not misleading. 
 (f) Further Agreement. The Selling Shareholder and Sohu will cooperate to the extent necessary to cause the Registration Statement
or any post-effective amendment thereto to become effective at the earliest practical time and will do and perform all things to be done and performed under this Agreement prior to any Closing Date and to satisfy all conditions precedent of the

 8. Indemnification and Contribution. (a) Indemnification of Underwriters by the

Act or Section 20 of the Exchange Act (each, an “Indemnified Party”), against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject, under the Act, the Exchange
Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in any part of any Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission of
a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with
investigating or defending against any loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the
enforcement of this provision with respect to any of the above as such expenses are incurred; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of
or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the
Representatives specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection 8(c) below. 
 (b) Indemnification of Underwriters by the Selling Shareholder and Sohu. The Selling Shareholder and Sohu, jointly and severally,
will indemnify and hold harmless each Indemnified Party against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state
statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any
part of any Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission of a material fact required to be
stated therein or necessary to make the statements therein not misleading, and will reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending against
any loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with
respect to any of the above as such expenses are incurred; provided, however, that the Selling Shareholder and Sohu will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based
upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives
specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection 8(c) below; provided further that, none of the Indemnified
Parties shall be entitled to seek indemnification under this Section 8(b) from the Selling Stockholder or Sohu unless both of the following conditions are met: (i) the Indemnified Party shall first have sought indemnity from the Company in
writing under Section 8(a) and (ii) the Company has not satisfied such request for indemnification in full within 30 days of written notification. Notwithstanding the foregoing, an Indemnified Party shall not be required to make an initial
demand on the Company if the Company has filed for bankruptcy protection, 

  

 34 

 
announced that it is insolvent, received a going-concern qualification from its independent auditors or announced that there is considerable doubt that it
will be able to continue as a going concern. 
 (c) Indemnification of the Company, the Selling Shareholder and Sohu.
Each Underwriter will severally and not jointly indemnify and hold harmless the Company, each of its directors and each of its officers who signs a Registration Statement and each person, if any, who controls the Company within the meaning of
Section 15 of the Act or Section 20 of the Exchange Act, the Selling Shareholder and Sohu (each, an “Underwriter Indemnified Party”), against any losses, claims, damages or liabilities to which such Underwriter Indemnified
Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in any part of any Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus, or any Issuer Free Writing Prospectus, or arise out of
or are based upon the omission or the alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or
alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives specifically for use therein, and will reimburse
any legal or other expenses reasonably incurred by such Underwriter Indemnified Party in connection with investigating or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether
or not such Underwriter Indemnified Party is a party thereto), whether threatened or commenced, based upon any such untrue statement or omission, or any such alleged untrue statement or omission as such expenses are incurred, it being understood and
agreed that the only such information furnished by any Underwriter consists of the following information in the Final Prospectus furnished on behalf of each Underwriter: the concession and reallowance figures appearing in the fourth paragraph and
sales to discretionary accounts appearing in the fifteenth paragraph and the information discussing possible stabilization measures appearing in the seventeenth and eighteenth paragraphs under the caption “Underwriting.” 
 (d) Actions against Parties; Notification. Promptly after receipt by an indemnified party under this Section of notice of the
commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a), (b) or (c) above, notify the indemnifying party of the commencement thereof; but the
failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a), (b) or (c) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive
rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a), (b) or
(c) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish,
jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party),
and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of
any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of
such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

  

 35 

 (e) Contribution. If the indemnification provided for in this Section is
unavailable or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses,
claims, damages or liabilities referred to in subsection (a), (b) or (c) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, the Selling Shareholder and Sohu on the one hand and the
Underwriters on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Company, the Selling Shareholder and Sohu on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims,
damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company, the Selling Shareholder and Sohu on the one hand and the Underwriters on the other shall be deemed to be in the same
proportion as the total net proceeds from the offering (before deducting expenses) received by the Company, the Selling Shareholder and Sohu bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault
shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, the Selling
Shareholder and Sohu or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the
losses, claims, damages or liabilities referred to in the first sentence of this subsection (e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending
any action or claim which is the subject of this subsection (e). Notwithstanding the provisions of this subsection (e), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the
Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or
alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The
Underwriters’ obligations in this subsection (e) to contribute are several in proportion to their respective underwriting obligations and not joint. The Company, the Selling Shareholder, Sohu and the Underwriters agree that it would not be
just and equitable if contribution pursuant to this Section 8(e) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of
the equitable considerations referred to in this Section 8(e). 
 9. Termination. The Representatives may terminate this
Agreement, by notice to the Company and the Selling Shareholder, at any time at or prior to the First Closing Date, if there has been (i) any change, or any development or event involving a prospective change, in the condition (financial or
otherwise), results of operations, business, properties or prospects of the Company and its Controlled Entities taken as a whole which, in the judgment of the Representatives, is material and adverse and makes it impractical or inadvisable to market
the Offered Securities; (ii) any downgrading in the rating of any debt securities of the Company by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 436(g)), or any public announcement that
any such organization has under surveillance or review its rating of any debt securities of the Company (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating);
(iii) any change, or any change or development involving a prospective change, in the United States, Cayman Islands, PRC or international financial, political or economic conditions or currency exchange rates or exchange controls the effect of
which is such as to make it, in the judgment of the Representatives, impractical to market or to enforce contracts for the sale of the Offered Securities, whether in the primary market 

  

 36 

 
or in respect of dealings in the secondary market; (iv) any suspension or material limitation of trading in securities generally on the New York Stock
Exchange, the Nasdaq Global Select Market, or any setting of minimum or maximum prices for trading on such exchange; (v) any suspension of trading of any securities of the Company on any exchange or in the over-the-counter market; (vi) any
banking moratorium declared by any U.S. federal, New York, Cayman Islands or PRC authorities; (vii) any major disruption of settlements of securities, payment or clearance services in the United States, Cayman Islands, PRC or any other country
where such securities are listed; or (viii) any attack on, outbreak or escalation of hostilities or act of terrorism involving the United States, Cayman Islands or PRC, any declaration of war by Congress or any other national or international
calamity or emergency if, in the judgment of the Representatives, the effect of any such attack, outbreak, escalation, act, declaration, calamity or emergency is such as to make it inadvisable to market the Offered Securities or to enforce contracts
for the sale of the Offered Securities. 
 10. Default of Underwriters. If any Underwriter or Underwriters default in their
obligations to purchase Offered Securities hereunder on either the First or any Optional Closing Date and the aggregate number of Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10%
of the total number of Offered Securities that the Underwriters are obligated to purchase on such Closing Date, the Representatives may make arrangements satisfactory to the Company, the Selling Shareholder and Sohu for the purchase of such Offered
Securities by other persons, including any of the Underwriters, but if no such arrangements are made by such Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to
purchase the Offered Securities that such defaulting Underwriters agreed but failed to purchase on such Closing Date. If any Underwriter or Underwriters so default and the aggregate number of Offered Securities with respect to which such default or
defaults occur exceeds 10% of the total number of Offered Securities that the Underwriters are obligated to purchase on such Closing Date and arrangements satisfactory to the Representatives, the Company, the Selling Shareholder and Sohu for the
purchase of such Offered Securities by other persons are not made within 24 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter, the Company, the Selling Shareholder or Sohu, except
as provided in Section 11 (provided that if such default occurs with respect to Optional Securities after the First Closing Date, this Agreement will not terminate as to the Firm Securities or any Optional Securities purchased prior to such
termination). As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10. Nothing herein will relieve a defaulting Underwriter from liability for its default. 

11. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other
statements of the Company, the Selling Shareholder and Sohu, or their respective officers, and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or
statement as to the results thereof, made by or on behalf of any Underwriter, the Company, the Selling Shareholder, Sohu, or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and
payment for the Offered Securities. If the purchase of the Offered Securities by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 10 hereof, the Company will
reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities, and the respective obligations of the Company, the Selling
Shareholder, Sohu and the Underwriters pursuant to Section 8 hereof shall remain in effect. In addition, if any Offered Securities have been purchased hereunder, the representations and warranties in Section 2 and all obligations under

 Exhibit D-1Exhibit 4(rr)

 Exhibit 4(rr) 
 FIRST AMENDMENT TO TERM LOAN AGREEMENT 
 THIS FIRST AMENDMENT TO TERM LOAN AGREEMENT (this
“Amendment”) dated as of May 7, 2009, by and among WASHINGTON REAL ESTATE INVESTMENT TRUST (the “Borrower”), each of the financial institutions a signatory thereto together with their assignees under Section 13.7. (the
“Lenders”) and WELLS FARGO BANK, NATIONAL ASSOCIATION (the “Agent”). 
 WHEREAS, the Borrower, the Lenders and the Agent
have entered into that certain Term Loan Agreement dated as of February 21, 2008, as modified by the Modification Agreement, dated as of May 6, 2008 between the Borrower and Wells Fargo Bank, National Association, as the sole Lender (as
amended, supplemented, restated, or otherwise modified from time to time, the “Loan Agreement”); 
 WHEREAS, the Borrower, the
Lenders party hereto and the Agent desire to amend the Loan Agreement to amend certain provisions of the Loan Agreement on the terms and conditions contained herein; 
 NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged by the parties hereto, the parties hereto hereby agree as follows: 
 Section 1. Definitions. Capitalized terms used in this Amendment and not otherwise defined herein shall have the respective meanings given
such terms in the Loan Agreement. 
 Section 2. Specific Amendments to Loan Agreement. The parties hereto agree that the Loan
Agreement is amended as follows: 
 (a) The Loan Agreement is amended by restating the definitions of “Applicable Margin”,
“Interest Period”, “LIBOR”, “Post-Default Rate” and “Termination Date” set forth in Section 1.1 of the Loan Agreement in their entireties as follows: 
 “Applicable Margin” means (a) for the period from the Agreement Date up to but excluding the First Amendment
Effective Date, (i) 1.50% with respect to LIBOR Loans and (ii) 0.0% with respect to Base Rate Loans and (b) for the period from the First Amendment Effective Date and thereafter, 2.75%. 
 “Interest Period” means (a) for the period from the Agreement Date up to but excluding the First Amendment Effective
Date, with respect to any LIBOR Loan, each period commencing on the date such LIBOR Loan is made or the last day of the next preceding Interest Period for such Loan and ending on the numerically corresponding day in the first, second, third or sixth
calendar month thereafter, as the Borrower may select in a Notice of Continuation or Notice of Conversion, as the case may be, except that each Interest Period that commences on the last Business Day of a calendar month (or on any day for which
there is no numerically corresponding day in the appropriate subsequent 

 
calendar month) shall end on the last Business Day of the appropriate subsequent calendar month, and (b) for the period from the First Amendment
Effective Date and thereafter, with respect to any LIBOR Loan, each period of one month commencing on the first Business Day of a calendar month and ending on the date immediately preceding the first Business Day of the next calendar month.

 Notwithstanding the foregoing: (a) if any Interest Period would otherwise end after the Termination Date, such Interest Period shall
end on the Termination Date and (b) notwithstanding the immediately preceding clause (a), no Interest Period of a LIBOR Loan shall have a duration of less than one month and, if the Interest Period for any Loan would otherwise be a shorter
period, such Loan shall not be available hereunder for such period. 
 “LIBOR” means, for any LIBOR Loan for
any Interest Period therefor, the average rate of interest per annum at which deposits in immediately available funds in Dollars are offered to the Agent (at approximately 11:00 a.m. Eastern time, two Business Days prior to the first day of such
Interest Period) by first class banks in the interbank Eurodollar market where the Eurodollar operations of the Agent are customarily conducted, for delivery on the first day of such Interest Period, such deposits being for a period of time equal or
comparable to such Interest Period and in an amount equal to or comparable to the principal amount of the LIBOR Loan to which such Interest Period relates. Each determination of LIBOR by the Agent shall, in absence of demonstrable error, be
conclusive and binding. Notwithstanding the foregoing, if at any time the Borrower does not maintain interest rate cap, swap or collar agreements or other agreements or arrangements to provide protection against fluctuations in interest (an
“Interest Rate Protection Mechanism”) as to a notional amount equal to at least 100% of the outstanding principal balance of the Loans (which Interest Rate Protection Mechanism shall be on terms, for periods and with counterparties
reasonably acceptable to Agent), then LIBOR for a portion of the Loans equal to the total principal balance of the Loans in excess of the notional amount of such Interest Rate Protection Mechanism shall not, in any event, be less than one and
three-quarters of one percent (1.75%). Further, for any period during which the Borrower does maintain an Interest Rate Protection Mechanism as to a notional amount equal to at least 100% of the outstanding principal balance of the Loans, provided
that the floating rate under such Interest Rate Protection Mechanism is determined by reference to LIBOR and that the initial counterparty under such Interest Rate Protection Mechanism is the Agent or an Affiliate of the Agent, then notwithstanding
the first sentence of this definition, LIBOR for any Interest Period shall have the same meaning given to the term LIBOR for the same period pursuant to such Interest Rate Protection Mechanism. 
 “Post-Default Rate” means, in respect of the principal of any Loan or any other Obligation that is not paid when due
(whether at stated maturity, by acceleration, by optional or mandatory prepayment or otherwise), a rate per annum equal to the rate of interest then in effect plus three percent (3.0%). 
  

 - 2 - 

 “Termination Date” means November 1, 2011. 
 (b) The Loan Agreement is further amended by adding the following definitions of “First Amendment Effective Date”, “Replacement Rate”
and “Replacement Rate Loan” in the proper alphabetical sequence in Section 1.1 of the Loan Agreement: 
 “First Amendment Effective Date” means May 7, 2009. 
 “Replacement Rate”
means the per annum rate of interest equal to the Federal Funds Rate plus one and one-half of one percent (1.50%) plus the Applicable Margin. Notwithstanding the foregoing, if at any time the Borrower does not maintain an Interest Rate
Protection Mechanism as to a notional amount equal to at least 100% of the outstanding principal balance of the Loans (which Interest Rate Protection Mechanism shall be on terms, for periods and with counterparties reasonably acceptable to Agent),
then the Replacement Rate for a portion of the Loans equal to the total principal balance of the Loans in excess of the notional amount of such Interest Rate Protection Mechanism shall not, in any event, be less than four and three-quarters of one
percent (4.75%). 
 “Replacement Rate Loan” means a Loan bearing interest at the Replacement Rate.

 (c) The Loan Agreement is further amended by restating Section 2.2.(a) of the Loan Agreement in its entirety as follows: 

(a) Rates. The Borrower promises to pay to the Agent for the account of each Lender interest on the unpaid principal amount of
the Loan made by such Lender for the period from and including the date of the making of such Loan to but excluding the date such Loan shall be paid in full, at the following per annum rates: 
 (i) for the period from the Agreement Date up to but excluding the First Amendment Effective Date, with respect to any portion of such
Loan that is a Base Rate Loan, at the Base Rate (as in effect from time to time), plus the Applicable Margin for Base Rate Loans; and with respect to any portion of such Loan that is a LIBOR Loan, at LIBOR for such Loan for the Interest Period
therefor, plus the Applicable Margin for LIBOR Loans; and 
 (ii) for the period from the First Amendment Effective Date and
thereafter, at LIBOR for the Interest Period, plus the Applicable Margin; provided, that if any Lender’s Loans, or all Lenders’ Loans, are converted into Replacement Rate Loans by reason of the circumstances specified in Sections 5.1.(b),
5.2., or 5.3., then such Lender’s Loans, or all Lender’s Loans, as the case may be, shall bear interest at the per annum rate equal to the Replacement Rate, which Replacement Rate shall become effective in accordance with the provisions of
5.2. and 5.5, as applicable, or on such date as the Agent may specify to the Borrower. So long as LIBOR is available and the Lenders have not suspended or 

  

 - 3 - 

 
ceased to continue LIBOR Loans in accordance with Article V., on the last day of each Interest Period such Loan shall automatically continue as a LIBOR Loan
for one additional Interest Period, in which case the per annum rate will be LIBOR for such new Interest Period, plus the Applicable Margin. 
 Notwithstanding the foregoing, during the continuance of an Event of Default, the Borrower shall pay to the Agent for the account of each Lender interest at the Post-Default Rate on the outstanding principal amount of
the Loan made by such Lender and on any other amount payable by the Borrower hereunder or under the Note held by such Lender to or for the account of such Lender (including without limitation, accrued and due but unpaid interest to the extent
permitted under Applicable Law). 
 (d) The Loan Agreement is further amended by restating Section 2.5.(a) of the Loan Agreement in its
entirety as follows: 
 (a) Optional. Subject to Section 3.6.(b) and Section 5.4., the Borrower may prepay
the Loans, in whole or in part, at any time without premium or penalty. The Borrower shall give the Agent at least 3 Business Days prior written notice of the prepayment of any Loan. 
 (e) The Loan Agreement is further amended by restating Sections 2.7. and 2.8. of the Loan Agreement in their entireties as follows: 
 Section 2.7. Reserved. 
 Section 2.8. Reserved. 
 (f) The Loan Agreement is further amended by restating Section 3.5.(a) of the Loan
Agreement in its entirety as follows: 
 (a) Reserved. 
 (g) The Loan Agreement is further amended by restating Section 3.6.(b) of the Loan Agreement in its entirety as follows: 
 (b) Prepayment Fee. If LIBOR Loans are prepaid on or before November 30, 2010, the Borrower shall pay to the Agent for the
benefit of each Lender, a prepayment fee equal to one percent (1.00%) times the amount of such prepayment. If LIBOR Loans are prepaid after November 30, 2010 but on or before May 31, 2011, the Borrower shall pay to the Agent for the
benefit of each Lender, a prepayment fee equal to one-quarter of one percent (0.25%) times the amount of such prepayment. No prepayment fee shall be due with respect to any LIBOR Loans that are prepaid after May 31, 2011, and no prepayment fee
shall to applicable to any prepayment of a Replacement Rate Loan. 
  

 - 4 - 

 (h) The Loan Agreement is further amended by restating Section 5.1.(b) of the Loan Agreement in its
entirety as follows: 
 (b) Lender’s Suspension of LIBOR Loans. Without limiting the effect of the provisions of
the immediately preceding subsection (a), if by reason of any Regulatory Change, any Lender either (i) incurs Additional Costs based on or measured by the excess above a specified level of the amount of a category of deposits or other
liabilities of such Lender that includes deposits by reference to which the interest rate on LIBOR Loans is determined as provided in this Agreement or a category of extensions of credit or other assets of such Lender that includes LIBOR Loans or
(ii) becomes subject to restrictions on the amount of such a category of liabilities or assets that it may hold, then, if such Lender so elects by notice to the Borrower (with a copy to the Agent), the obligation of such Lender to continue any
Loan as a LIBOR Loan hereunder shall be suspended until such Regulatory Change ceases to be in effect (in which case the provisions of Section 5.5. shall apply). 
 (i) The Loan Agreement is further amended by restating Sections 5.2., 5.3., 5.4. and 5.5. of the Loan Agreement in their entireties as follows: 
 Section 5.2. Suspension of LIBOR Loans. 
 Anything herein to the contrary notwithstanding, if, on or prior to the determination of LIBOR for any Interest Period: 
 (a) the Agent reasonably determines (which determination shall be conclusive) that quotations of interest rates for the relevant deposits referred to in the definition of LIBOR are not being provided in the relevant
amounts or for the relevant maturities for purposes of determining rates of interest for LIBOR Loans as provided herein or is otherwise unable to determine LIBOR, or 
 (b) the Agent reasonably determines (which determination shall be conclusive) that the relevant rates of interest referred to in the
definition of LIBOR upon the basis of which the rate of interest for LIBOR Loans for such Interest Period is to be determined are not likely to adequately cover the cost to any Lender of maintaining LIBOR Loans for such Interest Period; 

then the Agent shall give the Borrower and each Lender prompt notice thereof and, so long as such condition remains in effect, the Lenders shall be
under no obligation to, and shall not, continue LIBOR Loans after the last day of each current Interest Period for each outstanding LIBOR Loan, and such Loan shall convert into a Replacement Rate Loan. If the Agent gives notice to the Borrower (with
a copy to each Lender) that such conditions no longer remain in effect (which the Agent agrees to do promptly upon such conditions ceasing to be in effect), then, subject to Sections 5.1. and 5.3., the Lenders’ Replacement Rate Loans shall be
automatically converted to LIBOR Loans on the first day of the next succeeding Interest Period. 
  

 - 5 - 

 Section 5.3. Illegality. 
 Notwithstanding any other provision of this Agreement, if any Lender shall determine (which determination shall be conclusive and binding)
that it is unlawful for such Lender to honor its obligation to maintain LIBOR Loans hereunder, then such Lender shall promptly notify the Borrower thereof (with a copy of such notice to the Agent) and such Lender’s obligation to continue LIBOR
Loans shall be suspended until such time as such Lender may again maintain LIBOR Loans (in which case the provisions of Section 5.5. shall be applicable). 
 Section 5.4. Compensation. 
 The Borrower shall pay to the Agent for the account
of each Lender, upon the request of the Agent, such amount or amounts as the Agent shall determine in its sole discretion shall be sufficient to compensate each Lender for any loss, cost or expense attributable to any payment or prepayment (whether
mandatory or optional) of a LIBOR Loan for any reason (including, without limitation, acceleration) or to any conversion of a LIBOR Loan to a Replacement Rate Loan on a date other than the last day of the Interest Period for such Loan. 

Such compensation shall include, without limitation; in the case of a LIBOR Loan, an amount equal to the then present value of
(i) the amount of interest that would have accrued on such LIBOR Loan for the remainder of the Interest Period at the rate applicable to such LIBOR Loan, less (ii) the amount of interest that would accrue on the same LIBOR Loan for the
same period if LIBOR were set on the date on which such LIBOR Loan was repaid, prepaid or converted, as applicable, calculating present value by using as a discount rate LIBOR quoted on such date. Upon the Borrower’s request the Agent shall
provide the Borrower with a statement setting forth the basis for requesting compensation under this Section and the method for determining the amount thereof. Any such statement shall be conclusive absent manifest error. 
 Section 5.5. Treatment of Affected Loans. 
 If the obligation of any Lender to continue LIBOR Loans shall be suspended pursuant to Section 5.1.(b) or Section 5.3., then such Lender’s LIBOR Loans shall be automatically converted into Replacement
Rate Loans on the first Business Day of the calendar month following the last day of the then current Interest Period for such Lender’s LIBOR Loans (or in the case of a conversion to Replacement Rate Loans required by Section 5.1.(b) or
Section 5.3., on such earlier date as such Lender may specify by notice to the Borrower with a copy to the Agent) and, unless and until such Lender gives notice as provided below that the circumstances specified in Section 5.1. or
Section 5.3. that gave rise to such conversion no longer exist (which such Lender agrees to do promptly upon such circumstances ceasing to exist): 
 (a) to the extent that such Lender’s LIBOR Loans have been so converted, all payments and prepayments of principal that would otherwise be applied to such Lender’s LIBOR Loans shall be applied instead to its
Replacement Rate Loans; and 
  

 - 6 - 

 (b) all or any portion of such Lender’s Loans that would otherwise be continued by
such Lender as LIBOR Loans shall be continued instead as Replacement Rate Loans. 
 If a Lender gives notice to the Borrower
(with a copy to the Agent) that the circumstances specified in Section 5.1. or 5.3. that gave rise to the conversion of such Lender’s LIBOR Loans pursuant to this Section no longer exist (which such Lender agrees to do promptly upon such
circumstances ceasing to exist), then such Lender’s Replacement Rate Loans shall be automatically converted to LIBOR Loans on the first day of the next succeeding Interest Period. 
 (j) The Loan Agreement is further amended by restating Section 8.14 of the Loan Agreement in its entirety as follows: 
 Section 8.14. Reserved. 
 Section 3. Conditions Precedent. The effectiveness of this Amendment is subject to the following conditions precedent: 
 (a) The Agent shall have received each of the following, each in form and substance satisfactory to the Agent:

 (iv) a certificate of
incumbency signed by the Secretary or Assistant Secretary (or other individual performing similar functions) of each Loan Party with respect to each of the officers of such Person authorized to execute and deliver the Loan Documents to which such

 - 7 - 

 (v) such other documents, instruments and agreements as the Agent may reasonably request.

 (b) In the good faith of the Agent, as of the Business Day on which all of the conditions precedent set forth in Section 3(a) above
have been satisfied:

condition, situation or status since the date of the information contained in the financial and business projections, budgets, pro forma data and forecasts most recently delivered to the Agent and the Lenders concerning the Borrower and its
Subsidiaries that has had or could reasonably be expected to result in a Material Adverse Effect. 
 (ii) There shall not have
occurred any material adverse change in governmental regulation or policy that adversely affects the Agent, Lenders, the Borrower, the Borrower’s Subsidiaries, or any other Loan Parties. 
 Section 4. Representations. The Borrower represents and warrants to the Agent and the Lenders that: 
 (a) Authorization. The Borrower and each other Loan Party each has the right and power, and has taken all necessary action to authorize the
execution and delivery of this Amendment and to perform its obligations thereunder and under the Loan Agreement, as amended by this Amendment, in accordance with their respective terms. This Amendment has been duly executed and delivered by a duly
authorized officer of the Borrower and both this Amendment and the Loan Agreement, as amended by this Amendment, is a legal, valid and binding obligation of the Borrower and each other Loan Party enforceable against such Person in accordance with
its respective terms except as the enforceability thereof may be limited by bankruptcy, insolvency or similar laws affecting creditors rights generally. 
 (b) Compliance with Laws, etc. The execution, delivery and performance of this Amendment and the other Loan Documents to which any Loan Party is a party do not and will not, by the passage of time, the giving
of notice, or both: (i) require any Governmental Approval or violate any Applicable Law relating to any Loan Party or any Subsidiary; (ii) conflict with, result in a breach of or constitute a default under the organizational documents of
any Loan Party or any other Subsidiary, or any indenture, agreement or other instrument to which any Loan Party or any Subsidiary is a party or by which it or any of its properties may be bound; or (iii) result in or require the creation or
imposition of any Lien upon or with respect to any property now owned or hereafter acquired by any Loan Party or any other Subsidiary other than in favor of the Agent for the benefit of the Lenders. 
 (c) No Default. No Default or Event of Default has occurred and is continuing as of the date hereof nor will exist immediately after giving effect
