 NOW, THEREFORE, for and in consideration of the sum of TEN and NO/100 DOLLARS ($10.00),
and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto do hereby covenant and agree as follows: 
 1. Definitions. All the terms used herein which are not otherwise defined herein shall have the meanings set forth in the Credit Agreement. 

2. Modification of the Credit Agreement. Borrower, the Lenders and Agent do hereby modify and amend the Credit Agreement as
follows: 
 (a) By deleting in their entirety the definitions of “Delinquent Lender” and “Insolvent/Seized
Lender” in §1.1 of the Credit Agreement; 







 (b) By deleting in their entirety the definitions of “Applicable Margin”,
“Commitment Increase”, “Development Property”, “Interest Period”, “Material Subsidiary”, “Maturity Date”, “Required Lenders”, “Revolving Credit Loan or Loans”, “Swing Loan
Commitment” and “Total Commitment” in §1.1 of the Credit Agreement, and inserting in lieu thereof the following: 
 “Applicable Margin. (a) On any date, the Applicable Margin for LIBOR Rate Loans and Base Rate Loans shall be a percentage per annum as set forth below based on the ratio of the
Consolidated Total Indebtedness to the Borrower’s Gross Asset Value:

	  	 Less than or equal to 35%
	  	 	1.85	% 	 	 	0.85	% 
				
	 Pricing Level 2
	  	 Greater than 35% but less than or equal to 40%
	  	 	2.00	% 	 	 	1.00	% 
				
	 Pricing Level 3

	 Pricing Level 5
	  	 Greater than 52.5%
	  	 	2.50	% 	 	 	1.50	% 

 The initial Applicable Margin shall be at Pricing Level 1. At such
time as this subparagraph (a) is applicable, the Applicable Margin for each Base Rate Loan shall be determined by reference to the ratio of Consolidated Total Indebtedness to Gross Asset Value in effect from time to time, and the Applicable
Margin for any Interest Period for all LIBOR Rate Loans comprising part of the same borrowing shall be determined by reference to the ratio of Consolidated Total Indebtedness to Gross Asset Value in effect on the first (1st) day of such Interest Period. The Applicable Margin shall not
be adjusted based upon such ratio, if at all, until the first (1st) day of the first (1st) month following the delivery by REIT to the Agent of the Compliance Certificate after the end of a calendar quarter. In the event that REIT shall fail to deliver to the Agent a quarterly Compliance
Certificate on or before the date required by §7.4(c), then without limiting any other rights of the Agent and the Lenders under this Agreement, the Applicable Margin for Loans shall be at Pricing Level 5 until such failure is cured within any
applicable cure period, or waived in writing by the Required Lenders in which event the Applicable Margin shall adjust, if necessary, on the first (1st) day of the first (1st) month following receipt of such Compliance Certificate. 

(b) From and after the date that Agent first receives written notice from REIT or Borrower that Borrower has first
obtained an Investment Grade Rating, the Applicable Margin shall mean, as of any date of determination, a percentage per annum determined by reference to the Credit Rating Level as set forth below:

 At such time as this subparagraph (b) is applicable, the Applicable Margin for each Base Rate Loan
shall be determined by reference to the Credit Rating Level in effect from time to time, and the Applicable Margin for any Interest Period for all LIBOR Rate Loans comprising part of the same borrowing shall be determined by reference to the Credit
Rating Level in effect on the first day of such Interest Period; provided, however that no change in the Applicable Margin resulting from the application of the Credit Rating Levels or a change in the Credit Rating Level shall be effective until
three (3) Business Days after the date on which the Agent receives written notice of the application of the Credit Rating Levels or a change in such Credit Rating Level. From and after the first date that the Applicable Margin is based on
Borrower’s Investment Grade Rating pursuant to this subparagraph (b), the Applicable Margin shall no longer be calculated by reference to the ratio of Consolidated Total Indebtedness to Gross Asset Value (provided that any accrued interest
payable at the Applicable Margin determined by reference to the ratio of Consolidated Total Indebtedness to Gross Asset Value prior to such date shall be payable as provided in §2.6). 

Commitment Increase. An increase in the Total Commitment to not more than $400,000,000.00 pursuant to §2.11.

 Development Property. Real Estate owned or acquired by the Borrower or any of its Subsidiaries for
which Borrower or its Subsidiary has obtained the necessary permits (including a building permit to permit construction) and on which the Borrower or any of its Subsidiaries is actively pursuing construction only of one or more buildings for use as
a Data Center Property and for which construction is proceeding to completion without undue delay from permit delay or denial, construction delays or otherwise, all pursuant to the ordinary course of business of the Borrower or such Subsidiary.
Notwithstanding the foregoing, any such property will no longer be considered to be a Development Property at the earlier of (i) the point at which such property’s Capitalized Value exceeds its GAAP book value or (ii) twenty-four
(24) months following substantial completion of construction of the improvements related to such development (excluding tenant improvements), and shall thereafter be considered a Stabilized Property for the purposes of the calculation of Gross
Asset Value and Unencumbered Asset Value, as applicable. Each individual phase of a given development will be considered a separate and distinct Development Property for purposes of this definition. 

Interest Period. With respect to each LIBOR Rate Loan (a) initially, the period commencing on the Drawdown
Date of such LIBOR Rate Loan and ending one, two, three or six months thereafter, and (b) thereafter, each period commencing on the day following the last day of the next preceding Interest Period applicable to such Loan and ending on the last
day of one of the periods set forth above, as selected by the Borrower in a Loan Request or Conversion/Continuation Request; provided that all of the foregoing provisions relating to Interest Periods are subject to the following: 

(i) if any Interest Period with respect to a LIBOR Rate Loan would otherwise end on a day that is not a LIBOR Business
Day, such Interest Period shall end on the next succeeding LIBOR Business Day, unless such next succeeding LIBOR Business Day occurs in the next calendar month, in which case such Interest Period shall end on the next preceding LIBOR Business Day,
as determined conclusively by the Agent in accordance with the then current bank practice in London; 

  
 3 








 (ii) if the Borrower shall fail to give notice as provided in §4.1, the
Borrower shall be deemed to have requested a continuation of the affected LIBOR Rate Loan as a LIBOR Rate Loan on the last day of the then current Interest Period with respect thereto as provided in and subject to the terms of §4.1(c);

 (iii) any Interest Period pertaining to a LIBOR Rate Loan that begins on the last Business Day of a calendar
month (or on a day for which there is no numerically corresponding day in the calendar month at the end of such Interest Period) shall end on the last Business Day of the applicable calendar month; and 

(iv) no Interest Period relating to any LIBOR Rate Loan shall extend beyond the Maturity Date. 

Material Subsidiary. Any Subsidiary of the Borrower which is (a) a direct or indirect owner of an asset
included in determining the Unencumbered Asset Value or (b) a guarantor of or otherwise liable with respect to any other Unsecured Debt of the REIT, the Borrower or any of their respective Subsidiaries (other than any of such Subsidiaries that
are not organized under the laws of any political subdivision of the United States and which are not borrowers, guarantors or otherwise liable with respect to any Unsecured Debt of REIT, Borrower or any of their respective Subsidiaries which are
organized under the laws of any political subdivision of the United States). Notwithstanding the foregoing, Xeres Ventures LLC, Yak Ventures LLC and Alshain Ventures LLC shall not be deemed to be Material Subsidiaries so long as such Subsidiaries do
not guarantee any Unsecured Debt. 
 Maturity Date. March 21, 2016, as such date may be extended as
provided in §2.12, or such earlier date on which the Loans shall become due and payable pursuant to the terms hereof. 
 Required Lenders. As of any date, the Lender or Lenders whose aggregate Commitment Percentage is equal to or greater than sixty-six and 7/10 percent (66.7%) of the Total Commitment; provided
that in determining said percentage at any given time, all then existing Defaulting Lenders will be disregarded and excluded and the Commitment Percentages of the Lenders shall be redetermined for voting purposes only to exclude the Commitment
Percentages of such Defaulting Lenders. 
 Revolving Credit Loan or Loans. An individual Revolving Credit
Loan or the aggregate Revolving Credit Loans, as the case may be, in the maximum principal amount of $225,000,000.00 (subject to increase as provided in §2.11) to be made by the Lenders 

  
 4 








 
hereunder as more particularly described in §2. Without limiting the foregoing, Revolving Credit Loans shall also include Revolving Credit Loans made pursuant to §2.10(f). 

Swing Loan Commitment. The sum of $35,000,000.00, as the same may be changed from time to time in accordance with
the terms of this Agreement. 
 Total Commitment. The sum of the Commitments of the Lenders, as in effect
from time to time. As of the date of this Agreement, the Total Commitment is Two Hundred Twenty-Five Million and No/100 Dollars ($225,000,000.00). The Total Commitment may increase in accordance with §2.11.” 

(c) By inserting the following definitions in §1.1 of the Credit Agreement, in the appropriate alphabetical order: 

“Collateral Account. A special deposit account established by the Agent pursuant to §12.6 and under its
sole dominion and control. 
 Credit Rating. As of any date of determination, the higher of the credit
ratings (or their equivalents) then assigned to Borrower’s long-term senior unsecured non-credit enhanced debt by either of the Rating Agencies. A credit rating of BBB- from S&P is equivalent to a credit rating of Baa3 from Moody’s and
vice versa. A credit rating of BBB from S&P is equivalent to a credit rating of Baa2 from Moody’s and vice versa. A credit rating of BBB+ from S&P is equivalent to a credit rating of Baa1 by Moody’s and vice versa. A credit rating
of A- from S&P is equivalent to a credit rating of A3 from Moody’s and vice versa. It is the intention of the parties that if Borrower shall only obtain a credit rating from one of the Rating Agencies without seeking a credit rating from
the other of the Rating Agencies, the Borrower shall be entitled to the benefit of the Credit Rating Level for such credit rating. If Borrower shall have obtained a credit rating from both of the Rating Agencies, the higher of the two ratings shall
control, provided that the lower rating for such Person is only one level below that of the higher rating. If the lower rating for such Person is more than one level below that of the higher credit rating for such Person, the operative rating would
be deemed to be one rating level higher than the lower of the two ratings. In the event that Borrower shall have obtained a credit rating from either or both of the Rating Agencies and shall thereafter lose such rating or ratings (whether as a
result of withdrawal, suspension, election to not obtain a rating, or otherwise) from such Rating Agencies and as a result does not have a credit rating from any Rating Agency, Borrower shall be deemed for the purposes hereof not to have a credit
rating. Notwithstanding anything to the contrary contained herein, if at any time neither of the Rating Agencies shall perform the functions of a securities rating agency, then the Borrower and the Agent shall promptly negotiate in good faith to
agree upon a substitute rating agency (and to correlate the system of ratings of such substitute rating agency with that of the rating agency being replaced), and pending such amendment, the Credit Rating of any Rating Agency in effect immediately
prior to such time, shall continue to apply, provided that the designation of such replacement agency and such amendment are completed within thirty (30) days of such event, and if not so completed within such thirty (30) day period,
Credit Rating Level 5 shall be the applicable Credit Rating Level until such time as Borrower obtains a Credit Rating from a Rating Agency.

 Credit Rating Level. One of the following five pricing levels, as
applicable, and provided, further, that, from and after the time that Agent receives written notice that Borrower has first obtained an Investment Grade Rating, during any period that Borrower has no Credit Rating Level, Credit Rating Level 5 shall
be the applicable Credit Rating Level: 
 “Credit Rating Level 1” means the Credit Rating Level
which would be applicable for so long as the Credit Rating is greater than or equal to A- by S&P or A3 by Moody’s; 
 “Credit Rating Level 2” means the Credit Rating Level which would be applicable for so long as the Credit Rating is greater than or equal to BBB+ by S&P or Baa1 by Moody’s and
Credit Rating Level 1 is not applicable; 
 “Credit Rating Level 3” means the Credit Rating
Level which would be applicable for so long as the Credit Rating is greater than or equal to BBB by S&P or Baa2 by Moody’s and Credit Rating Levels 1 and 2 are not applicable; 

“Credit Rating Level 4” means the Credit Rating Level which would be applicable for so long as the Credit
Rating is greater than or equal to BBB- by S&P or Baa3 by Moody’s and Credit Rating Levels 1, 2 and 3 are not applicable; and 
 “Credit Rating Level 5” means the Credit Rating Level which would be applicable for so long as the Credit Rating is less than BBB- by S&P or Baa3 by Moody’s or there is no Credit
Rating. 
 Defaulting Lender. Any Lender that (a) has failed to perform any of its funding
obligations hereunder, including in respect of its Loans or participations in respect of Letters of Credit or Swing Loans, within two (2) Business Days of the date required to be funded by it hereunder and such failure is continuing, unless
such Lender notifies the Agent and the Borrower in writing that such failure is the result of such Lender’s determination that one or more conditions precedent to funding (each of which conditions precedent, together with any applicable
default, shall be specifically identified in such writing) has not been satisfied, (b) (i) has notified the Borrower, the Agent or any Lender that it does not intend to comply with its funding obligations hereunder or (ii) has made a
public statement to that effect with respect to its funding obligations under other agreements generally in which it commits to extend credit, unless with respect to this clause (b), such notice or public statement relates to such Lender’s
obligation to fund a Revolving Credit Loan hereunder and states that such position is based on such Lender’s determination that a condition precedent to funding (which condition precedent, together with any applicable default, shall be
specifically identified in such notice or public statement) cannot be satisfied, (c) has failed, within two (2) Business Days after request by the Agent or the Borrower, to confirm in a manner reasonably satisfactory to the Agent and the
Borrower that it will comply with its funding obligations; provided that, notwithstanding the provisions of §2.13, such Lender shall cease to be a Defaulting Lender upon the Agent’s and Borrower’s receipt of confirmation that such
Defaulting Lender will comply with its funding obligations, or (d) has, or has a direct or indirect parent company that has, (i) become the subject of a proceeding under any bankruptcy,

similar capacity, (ii) had a receiver, conservator, trustee, administrator, assignee for the benefit of creditors or similar Person, including the Federal Deposit Insurance Corporation or any other state or federal regulatory authority acting
in such capacity, charged with reorganization or liquidation of its business or a custodian appointed for it, or (iii) taken any action in furtherance of, or indicated its consent to, approval of or acquiescence in any such proceeding or
appointment; provided that a Lender shall not be a Defaulting Lender solely by virtue of the ownership or acquisition of any equity interest in that Lender or any direct or indirect parent company thereof by a governmental authority (including any
agency, instrumentality, regulatory body, central bank or other authority) so long as such ownership interest does not result in or provide such Lender with immunity from the jurisdiction of courts of the United States or from the enforcement of
judgments or writs of attachment of its assets or permit such Lender (or such governmental authority or instrumentality) to reject, repudiate, disavow, or disaffirm any contracts or agreements made with such Person). Any determination by the Agent
that a Lender is a Defaulting Lender under any one or more of clauses (a) through (d) above shall be conclusive and binding absent manifest error, and such Lender shall be deemed to be a Defaulting Lender (subject to §2.13(g)) upon
delivery of written notice of such determination to the Borrower and each Lender.

Unused Fee. See §2.3(a).” 
 (d) By deleting in its entirety §2.3 of the Credit Agreement, and inserting in lieu thereof the following: 
 “§2.3 Unused Fee; Facility Fee. 
 (a) The Borrower agrees to pay to the Agent for the account of the Lenders that are Non-Defaulting Lenders in accordance with their respective Commitment Percentages an unused fee (the “Unused
Fee”) calculated at the rate per annum as set forth below on the average daily amount by which the Total Commitment exceeds the outstanding principal amount of Revolving Credit Loans, Swing Loans and the face amount of Letters of Credit
Outstanding during each calendar quarter or portion thereof commencing on the date hereof and ending on the Maturity Date, subject to §2.3(b). The Unused Fee shall be calculated for each day based on the ratio (expressed as a percentage) of
(a) the average daily amount of the outstanding principal amount of the Revolving Credit Loans and Swing Loans and the face amount of Letters of Credit Outstanding during such quarter to (b) the Total Commitment, and if such ratio is less
than fifty percent (50%), the Unused Fee shall be payable at the rate of 0.35%, and if such ratio is equal to or greater than fifty percent (50%), the Unused Fee shall be payable at the rate of 0.25%. The Unused Fee shall be payable quarterly in
arrears on the first (1st) day of each calendar
quarter for the immediately preceding calendar quarter or portion thereof, and on any earlier date on which the Commitments shall be reduced or shall terminate as provided in §2.4, with a final payment on the Maturity Date. 

(b) From and after the date that Agent receives written notice that Borrower has first obtained an Investment Grade
Rating, the Unused Fee shall no longer accrue (but any accrued Unused Fee shall be payable as provided in §2.3(a)), and from and thereafter, the Borrower agrees to pay to the Agent for the account of the Lenders that are Non-Defaulting Lenders
in accordance with their respective Commitment Percentages a facility fee (the “Facility Fee”) calculated at the rate per annum set forth below based upon the applicable Credit Rating Level on the Total Commitment:

 The Facility Fee shall be calculated for each day and shall be payable
quarterly in arrears on the first (1st) day of each
fiscal quarter for the immediately preceding fiscal quarter or portion thereof, and on any earlier date on which the Commitments shall be reduced or shall terminate as provided in §2.4, with a final payment on the Maturity Date. The Facility
Fee shall be determined by reference to the Credit Rating Level in effect from time to time; provided, however, that no change in the Facility Fee rate resulting from a change in the Credit Rating Level shall be effective until three
(3) Business Days after the date on which the Agent receives written notice of a change.” 
 (e) By deleting in its
entirety §2.5(a) of the Credit Agreement, and inserting in lieu thereof the following: 
 “(a) Subject
to the terms and conditions set forth in this Agreement, Swing Loan Lender agrees to lend to the Borrower (the “Swing Loans”), and the Borrower may borrow (and repay and reborrow) from time to time between the Closing Date and the date
which is five (5) Business Days prior to the Maturity Date upon notice by the Borrower to the Swing Loan Lender given in accordance with this §2.5, such sums as are requested by the Borrower for the purposes set forth in §2.9 in an
aggregate principal amount at any one time outstanding not exceeding the Swing Loan Commitment; provided that in all events (i) no Default or Event of Default shall have occurred and be continuing; (ii) the outstanding principal
amount of the Revolving Credit Loans and Swing Loans (after giving effect to all amounts requested) plus Letter of Credit Liabilities shall not at any time exceed the Total Commitment; and (iii) the outstanding principal amount of the
Revolving Credit Loans and Swing Loans (after giving effect to all amounts requested), plus Letter of Credit Liabilities shall not at any time exceed the lesser of (A) the Total Commitment or (B) the Borrowing Base Availability (giving
effect to the amount of all Outstanding Revolving Credit Loans, Swing Loans and Letter of Credit Liabilities). Notwithstanding anything to the contrary contained in this §2.5, the Swing Loan Lender shall not be obligated to make any Swing Loan
at a time when any other Lender is a Defaulting Lender, unless the Swing Loan Lender is reasonably satisfied that the participation therein will otherwise be fully allocated to the Lenders that are Non-Defaulting Lenders consistent with
§2.13(c) and the Defaulting Lender shall not participate therein, except to the extent the Swing Loan Lender has entered into arrangements with the Borrower or such Defaulting Lender that are satisfactory to the Swing Loan Lender in its good
faith determination to eliminate the Swing Loan Lender’s Fronting Exposure with respect to any such Defaulting Lender, including the delivery of cash collateral. Swing Loans shall constitute “Revolving Credit Loans” for all purposes
hereunder. The funding of a Swing Loan hereunder shall constitute a representation and warranty by the Borrower that all of the conditions set forth in §10 and §11 have been satisfied on the date of such funding. The Swing Loan Lender may
assume that the conditions in §10 and §11 have been satisfied unless Swing Loan Lender has received written notice from a Lender that such conditions have not been satisfied. Each Swing Loan shall be due and payable within five
(5) Business Days of the date such Swing Loan was provided and Borrower hereby agree (to the extent not repaid as contemplated by §2.5(d) below) to repay each Swing Loan on or before the date that is five (5) Business Days from the
date such Swing Loan was provided.”

 (f) By deleting the words and numbers “five (5)” appearing in the next to last
line of §2.7, and inserting in lieu thereof the words and numbers “eight (8)”; 
 (g) By deleting in its entirety
§2.10(a) of the Credit Agreement, and inserting in lieu thereof the following: 
 “(a) Subject to the
terms and conditions set forth in this Agreement, at any time and from time to time from the Closing Date through the day that is ninety (90) days prior to the Maturity Date, the Issuing Lender shall issue such Letters of Credit as the Borrower
may request upon the delivery of a written request in the form of Exhibit E hereto (a “Letter of Credit Request”) to the Issuing Lender, provided that (i) no Default or Event of Default shall have occurred and be
continuing, (ii) upon issuance of such Letter of Credit, the Letter of Credit Liabilities shall not exceed Thirty-Five Million Dollars ($35,000,000.00), (iii) in no event shall the sum of (A) the Revolving Credit Loans Outstanding,
(B) the Swing Loans Outstanding and (C) the amount of Letter of Credit Liabilities (after giving effect to all Letters of Credit requested) exceed the Total Commitment, (iv) in no event shall the aggregate outstanding principal amount
of the Revolving Credit Loans, outstanding principal amount of Swing Loans and aggregate Letters of Credit Liabilities (after giving effect to any requested Letters of Credit) exceed the lesser of (A) the Total Commitment or (B) the
Borrowing Base Availability (giving effect to the amount of all Outstanding Revolving Credit Loans, Outstanding Swing Loans and aggregate Letter of Credit Liabilities), or cause a violation of the covenant set forth in §9.1, (v) the
conditions set forth in §§10 and 11 shall have been satisfied, and (vi) in no event shall any amount drawn under a Letter of Credit be available for reinstatement or a subsequent drawing under such Letter of Credit. Notwithstanding
anything to the contrary contained in this §2.10, the Issuing Lender shall not be obligated to issue, amend, extend, renew or increase any Letter of Credit at a time when any other Lender is a Defaulting Lender, unless the Issuing Lender is
reasonably satisfied that the participation therein will otherwise be fully allocated to the Lenders that are Non-Defaulting Lenders consistent with §2.13(c) and the Defaulting Lender shall have no participation therein, except to the extent
the Issuing Lender has entered into arrangements with the Borrower or such Defaulting Lender which are satisfactory to the Issuing Lender in its good faith determination to eliminate the Issuing Lender’s Fronting Exposure with respect to any
such Defaulting Lender, including the delivery of cash collateral. The Issuing Lender may assume that the conditions in §10 and §11 have been satisfied unless it receives written notice from a Lender that such conditions have not been
satisfied. Each Letter of Credit Request shall be executed by an Authorized Officer of Borrower. The Issuing Lender shall be entitled to conclusively rely on such Person’s authority to request a Letter of Credit on behalf of Borrower. The
Issuing Lender shall have no duty to verify the authenticity of any signature appearing on a Letter of Credit Request. The Borrower assumes all risks with respect to the use of the Letters of Credit. Unless the Issuing Lender and the Required
Lenders otherwise consent, the term of any Letter of Credit shall not exceed a period of time commencing on the issuance of the Letter of Credit and ending one year after the date of issuance thereof, subject to extension pursuant to an
“evergreen” clause acceptable to Agent and Issuing Lender (but in any event the term shall not extend beyond the Maturity Date). The amount available to be drawn under any Letter of Credit shall reduce on a dollar-for-dollar basis the
amount available to be drawn under the Total Commitment as a Revolving Credit Loan.”

 (h) By deleting in its entirety §2.10(e) of the Credit Agreement, and inserting in lieu
thereof the following: 
 “(e) Upon the issuance of each Letter of Credit, the Borrower shall pay to the
Issuing Lender (i) for its own account, a Letter of Credit fronting fee calculated at the rate per annum equal to one-eighth of one percent (0.125%), and (ii) for the accounts of the Lenders that are Non-Defaulting Lenders (including the
Issuing Lender) in accordance with their respective percentage shares of participation in such Letter of Credit, a Letter of Credit fee calculated at the rate per annum equal to the Applicable Margin for LIBOR Rate Loans on the amount available to
be drawn under such Letter of Credit. Such fees shall be payable in quarterly installments in arrears with respect to each Letter of Credit on the first day of each calendar quarter following the date of issuance and continuing on each quarter or
portion thereof thereafter, as applicable, or on any earlier date on which the Commitments shall terminate and on the expiration or return of any Letter of Credit. In addition, the Borrower shall pay to Issuing Lender for its own account within five
(5) days of demand of Issuing Lender the standard issuance, documentation and service charges for Letters of Credit issued from time to time by Issuing Lender.” 
 (i) By deleting in its entirety the first sentence of §2.11(a) of the Credit Agreement, and inserting in lieu thereof the following: 

“Provided that no Default or Event of Default has occurred and is continuing, subject to the terms and conditions set
forth in this §2.11, the Borrower shall have the option (but subject to Agent’s prior written consent in each instance, which consent shall not be unreasonably withheld) at any time and from time to time before the date which is ninety
(90) days prior to the Maturity Date to request an increase in the Total Commitment to not more than $400,000,000.00 by giving written notice to the Agent (an “Increase Notice”; and the amount of such requested increase is the
“Commitment Increase”), provided that any such individual increase must be in a minimum amount of $5,000,000.00.” 
 (j) By deleting the date “May 6, 2014” appearing in the second
(2nd) line of §2.12 of the Credit Agreement, and
inserting in lieu thereof the date “March 21, 2017”; 
 (k) By deleting the words and numbers
“fifty (50) basis points” appearing in the third (3rd) line of §2.12(b) of the Credit Agreement, and inserting in lieu thereof the words and numbers “twenty five (25) basis points”: 

(l) By inserting the following as new §2.13 to the Credit Agreement: 

“§2.13 Defaulting Lenders. 

(a) If for any reason any Lender shall be a Defaulting Lender, then, in addition to the rights and remedies that may be
available to the Agent or the Borrower under this Agreement or applicable law, such Defaulting Lender’s right to participate in the administration of the Revolving Credit Loans, this Agreement and the other Loan Documents, including without
limitation, any right to vote in respect of, to consent to or to direct any action or inaction of the Agent or to be taken into account in the calculation of the Required Lenders or all of the Lenders, shall be suspended during the pendency of


  
 11 









 
such failure or refusal. If a Lender is a Defaulting Lender because it has failed to make timely payment to the Agent of any amount required to be paid to the Agent hereunder (without giving
effect to any notice or cure periods), in addition to other rights and remedies which the Agent or the Borrower may have hereunder or otherwise, the Agent shall be entitled (i) to collect interest from such Defaulting Lender on such delinquent
payment for the period from the date on which the payment was due until the date on which the payment is made at the Federal Funds Effective Rate, (ii) to withhold or setoff and to apply in satisfaction of the defaulted payment and any related
interest, any amounts otherwise payable to such Defaulting Lender under this Agreement or any other Loan Document in accordance with §2.13(d) and (iii) to bring an action or suit against such Defaulting Lender in a court of competent
jurisdiction to recover the defaulted amount and any related interest. Any amounts received by the Agent in respect of a Defaulting Lender’s Revolving Credit Loans and/or Commitment shall be applied as set forth in §2.13(d). 

(b) Any Non-Defaulting Lender may, but shall not be obligated, in its sole discretion, to acquire all
or a portion of a Defaulting Lender’s Commitment. Any Lender desiring to exercise such right shall give written notice thereof to the Agent and the Borrower no sooner than two (2) Business Days and not later than five (5) Business
Days after such Defaulting Lender became a Defaulting Lender. If more than one Lender exercises such right, each such Lender shall have the right to acquire its pro rata share of such Defaulting Lender’s Commitment in proportion to the
Commitments of the other Lenders exercising such right. If after such fifth (5th) Business Day, the Lenders have not elected to purchase all of the Commitment of such Defaulting Lender, then the Borrower (so long as no Default or Event of Default exists) or the Required Lenders
may, by giving written notice thereof to the Agent, the Borrower, such Defaulting Lender and the other Lenders, demand (but shall have no obligation to so demand) that such Defaulting Lender assign its Commitment to an assignee subject to and in
accordance with the provisions of §18.1 for the purchase price provided for below and upon any such demand such Defaulting Lender shall comply with such demand and shall consummate such assignment (subject to and in accordance with the
provisions of §18.1). No party hereto shall have any obligation whatsoever to initiate any such replacement or to assist in finding an assignee. Upon any such purchase or assignment, and any such demand with respect to which the conditions
specified in §18.1 have been satisfied, the Defaulting Lender’s interest in its Commitments, Revolving Credit Loans and rights hereunder (but not its liability in respect thereof or under the Loan Documents or this Agreement to the extent
the same relate to the period prior to the effective date of the purchase) shall terminate on the date of purchase and assignment, and the Defaulting Lender shall promptly execute all documents reasonably requested to surrender and transfer such
interest to the purchaser or assignee thereof, including an appropriate Assignment and Acceptance Agreement. The purchase price for the Commitment of a Defaulting Lender shall be equal to the amount of the principal balance of the Revolving Credit
Loans outstanding and owed by the Borrower to the Defaulting Lender plus any accrued but unpaid interest thereon and any accrued but unpaid fees incurred prior to such Lender becoming a Defaulting Lender. Prior to payment of such purchase price to a
Defaulting Lender, the Agent shall apply against such purchase price any amounts retained by the Agent pursuant to §2.13(d). 

  
 12 









 (c) During any period in which there is a Defaulting Lender, all or any part
of such Defaulting Lender’s obligation to acquire, refinance or fund participations in Letters of Credit pursuant to §2.10(g) or Swing Loans pursuant to §2.5(e) shall be reallocated among the Lenders that are Non-Defaulting Lenders in
accordance with their respective Commitment Percentages (computed without giving effect to the Commitment of such Defaulting Lender; provided that (i) each such reallocation shall be given effect only if, at the date the applicable
Lender becomes a Defaulting Lender, no Default or Event of Default exists, (ii) the conditions set forth in §10 and §11 are satisfied at the time of such reallocation (and, unless the Borrower shall have notified the Agent at such
time, the Borrower shall be deemed to have represented and warranted that such conditions are satisfied at the time), (iii) the representations and warranties in the Loan Documents shall be true and correct in all material respects on and as of
the date of such reallocation with the same effect as though made on and as of such date, except to the extent of changes resulting from transactions permitted by the Loan Documents (it being understood and agreed that any representation or warranty
which by its terms is made as of a specified date shall be required to be true and correct only as of such specified date), and (iv) the aggregate obligation of each Lender that is a Non-Defaulting Lender to acquire, refinance or fund
participations in Letters of Credit and Swing Loans shall not exceed the positive difference, if any, of (A) the Commitment of that Non-Defaulting Lender minus (B) the sum of (1) the aggregate outstanding principal amount of the
Revolving Credit Loans of that Lender plus (2) such Lender’s pro rata portion in accordance with its Commitment Percentage of outstanding Letter of Credit Liabilities and participations in Swing Loans. No reallocation hereunder shall
constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a Non-Defaulting Lender as a result of such Non-Defaulting
Lender’s increased exposure following such reallocation. 
 (d) Any payment of principal, interest, fees or
other amounts received by the Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, or otherwise, and including any amounts made available to the Agent for the account of such Defaulting Lender pursuant to
§13), shall be applied at such time or times as may be determined by the Agent as follows: first, to the payment of any amounts owing by such Defaulting Lender to the Agent (other than with respect to Letter of Credit Liabilities)
hereunder; second, to the payment of any amounts owing by such Defaulting Lender to the Issuing Lender (with respect to Letter of Credit Liabilities) and/or the Swing Loan Lender hereunder; third, if so determined by the Agent or
requested by the Issuing Lender or the Swing Loan Lender, to be held as cash collateral for future funding obligations of such Defaulting Lender of any participation in any Letter of Credit or Swing Loan; fourth, as the Borrower may request
(so long as no Default or Event of Default exists), to the funding of any Revolving Credit Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Agent;
fifth, if so determined by the Agent and the Borrower, to be held in a non-interest bearing deposit account and released pro rata in order to (x) satisfy obligations of such Defaulting Lender to fund Revolving Credit Loans or
participations under this Agreement and (y) be held as cash collateral for future funding obligations of such Defaulting Lender of any participation in any Letter of Credit or Swing Loan; sixth, to the payment of any amounts owing to the
Agent or the Lenders (including the Issuing Lender and the Swing Loan Lender) as a result of any judgment of 

  
 13 









 
a court of competent jurisdiction obtained by the Agent or any Lender (including the Issuing Lender and the Swing Loan Lender) against such Defaulting Lender as a result of such Defaulting
Lender’s breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction
obtained by the Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to such Defaulting Lender or as otherwise directed by a court of competent
jurisdiction; provided that if (i) such payment is a payment of the principal amount of any Revolving Credit Loans or funded participations in Letters of Credit or Swing Loans in respect of which such Defaulting Lender has not fully
funded its appropriate share and (ii) such Revolving Credit Loans or funded participations in Letters of Credit or Swing Loans were made at a time when the conditions set forth in §10 and §11, to the extent required by this Agreement,
were satisfied or waived, such payment shall be applied solely to pay the Revolving Credit Loans of, and funded participations in Letters of Credit or Swing Loans owed to, all Non-Defaulting Lenders on a pro rata basis until such time as all
Revolving Credit Loans and funded and unfunded participations in Letters of Credit and Swing Loans are held by the Lenders pro rata in accordance with their Commitment Percentages without regard to §2.13(c), prior to being applied to the
payment of any Revolving Credit Loans of, or funded participations in Letters of Credit or Swing Loans owed to, such Defaulting Lender. Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to
pay amounts owed by a Defaulting Lender or to post cash collateral pursuant to this §2.13(d) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto, and to the extent allocated to the
repayment of principal of the Revolving Credit Loan, shall not be considered outstanding principal under this Agreement. 
 (e) Within five (5) Business Days of demand by the Issuing Lender or Swing Loan Lender from time to time, the Borrower shall deliver to the Agent for the benefit of the Issuing Lender and the Swing
Loan Lender cash collateral in an amount sufficient to cover all Fronting Exposure with respect to the Issuing Lender and Swing Loan Lender (after giving effect to §2.5(a), §2.10(a) and §2.13(c)) on terms reasonably satisfactory to
the Issuing Lender and/or Swing Loan Lender in its good faith determination (and such cash collateral shall be in Dollars). Any such cash collateral shall be deposited in the Collateral Account as collateral (solely for the benefit of the Issuing
Lender and/or the Swing Loan Lender) for the payment and performance of each Defaulting Lender’s pro rata portion in accordance with their respective Commitment Percentages of outstanding Letter of Credit Liabilities and Swing Loans. Moneys in
the Collateral Account deposited pursuant to this section shall be applied by the Agent to reimburse the Issuing Lender and/or the Swing Loan Lender immediately for each Defaulting Lender’s pro rata portion in accordance with their respective
Commitment Percentages of any funding obligation with respect to a Letter of Credit or Swing Loan which has not otherwise been reimbursed by the Borrower or such Defaulting Lender. Any amounts deposited in the Collateral Account (or any portion
thereof) shall be refunded to the Borrower promptly upon any of the following (as applicable) (i) the applicable Letter of Credit in connection with which it was provided being terminated or cancelled (without any drawing thereon),
(ii) all Fronting Exposure with respect to the Issuing Lender and Swing Loan Lender has been eliminated or (iii) as provided in §§12.1 and 12.6(d) and (f). 

  
 14 









 (f) (i) Each Lender that is a Defaulting Lender shall not be entitled to
receive any Unused Fee or Facility Fee pursuant to §2.3 for any period during which that Lender is a Defaulting Lender. 
 (ii) Each Lender that is a Defaulting Lender shall not be entitled to receive Letter of Credit fees pursuant to §2.10(e) for any period during which that Revolving Credit Lender is a Defaulting
Lender. 
 (iii) With respect to any Unused Fee, Facility Fee or Letter of Credit fees not required to be paid to
any Defaulting Lender pursuant to clause (i) or (ii) above, the Borrower shall (x) pay to each Non-Defaulting Lender that is a Lender that portion of any such fee otherwise payable to such Defaulting Lender with respect to such
Defaulting Lender’s participation in Letter of Credit Liabilities or Swing Loans that has been reallocated to such Non-Defaulting Lender pursuant to §2.13(c), (y) pay to the Issuing Lender and Swing Loan Lender the amount of any such
fee otherwise payable to such Defaulting Lender to the extent allocable to the Issuing Lender’s or Swing Loan Lender’s Fronting Exposure to such Defaulting Lender and (z) not be required to pay any remaining amount of any such fee.

 (g) If the Borrower (so long as no Default or Event of Default exists) and the Agent agree in writing in their
sole discretion that a Defaulting Lender should no longer be deemed to be a Defaulting Lender, the Agent will so notify the parties hereto, whereupon as of the date specified in such notice and subject to any conditions set forth therein (which may
include arrangements with respect to any cash collateral), that Lender will, to the extent applicable, purchase that portion of outstanding Revolving Credit Loans of the other Lenders or take such other actions as the Agent may determine to be
necessary to cause the Revolving Credit Loans and funded and unfunded participations in Letters of Credit and Swing Loans to be held on a pro rata basis by the Lenders in accordance with their Commitments (without giving effect to §2.13(c)),
whereupon such Lender will cease to be a Defaulting Lender and any applicable cash collateral provided by the Borrower shall be promptly refunded to the Borrower; provided that no adjustments will be made retroactively with respect to fees
accrued or payments made by or on behalf of the Borrower while such Lender was a Defaulting Lender (including any application of such payments pursuant to §2.13(d)); and provided, further, that except to the extent otherwise
expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from such Lender’s having been a Defaulting Lender.” 

(m) By deleting the word and number “five (5)” appearing in the twelfth (12th) line of §4.1(a) of the Credit Agreement, and inserting in
lieu thereof the word and number “eight (8)”;

thereof the following: 
 “(b) All payments by the Borrower hereunder and under any of the other Loan
Documents shall be made without setoff or counterclaim and free and clear of and without deduction for any taxes (other than (i) income or franchise taxes imposed on any Lender and (ii) U.S. federal taxes imposed by reason of a
Lender’s failure to comply with the requirements of FATCA to establish that such payment is exempt from withholding tax thereunder), levies, imposts, duties, charges, fees, deductions, withholdings, compulsory loans, restrictions or conditions
of any nature now or hereafter imposed or levied by any jurisdiction or any political subdivision thereof or taxing or other authority therein unless the Borrower is compelled by law to make such deduction or withholding. If any such obligation
(other than income or franchise taxes imposed on any Lender) is imposed upon the Borrower with respect to any amount payable by it hereunder or under any of the other Loan Documents, the Borrower will pay to the Agent, for the account of the Lenders
(including the Swing Loan Lender) or (as the case may be) the Agent, on the date on which such amount is due and payable hereunder or under such other Loan Document, such additional amount in Dollars as shall be necessary to enable the Lenders or
the Agent to receive the same net amount which the Lenders or the Agent would have received on such due date had no such obligation been imposed upon the Borrower. The Borrower will deliver promptly to the Agent certificates or other valid vouchers
for all taxes or other charges deducted from or paid with respect to payments made by the Borrower hereunder or under any other Loan Document.” 
 (p) By inserting the following at the end of §4.4(c) of the Credit Agreement as part of §4.4(c): 
 “Without limitation of the foregoing, if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding tax imposed by FATCA if such Lender were to fail to comply
with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Agent at the time or times prescribed by law and at such
time or times reasonably requested by the Borrower or the Agent such documentation prescribed by applicable law (including as prescribed by Sections 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower
or the Agent as may be necessary for the Borrower and the Agent to comply with their obligations under FATCA and to determine that such Lender has or has not complied with such Lender’s obligations under FATCA or, as necessary, to determine the
amount to deduct and withhold from such payment. Solely for purposes of the preceding sentence, “FATCA” shall include any amendments to FATCA after the date of this Agreement.” 

(q) By deleting in its entirety §4.10 of the Credit Agreement, and inserting in lieu thereof the following: 

“§4.10 Capital Adequacy. If after the date hereof any Lender determines that (a) the adoption of or
change in any law, rule, regulation or guideline regarding capital requirements for banks or bank holding companies or any change in the interpretation or application thereof by any governmental authority charged with the administration thereof, or
(b) compliance by such Lender or its parent bank holding company with any guideline, request or directive of any such entity regarding capital adequacy or liquidity requirements (whether or not having the force of law), has the effect of
reducing the 

  
 16 









 
return on such Lender’s or such holding company’s capital as a consequence of such Lender’s commitment to make Loans or participate in Letters of Credit hereunder to a level below
that which such Lender or holding company could have achieved but for such adoption, change or compliance (taking into consideration such Lender’s or such holding company’s then existing policies with respect to capital adequacy or
liquidity position) by any amount deemed by such Lender to be material, then such Lender may notify the Borrower thereof. The Borrower agrees to pay to such Lender the amount of such reduction in the return on capital as and when such reduction is
determined, upon presentation by such Lender of a statement of the amount setting forth the Lender’s calculation thereof. In determining such amount, such Lender may use any reasonable averaging and attribution methods generally applied by such
Lender. For purposes of §4.9 and §4.10, the Dodd-Frank Wall Street Reform and Consumer Protection Act and all requests, rules, publications, orders, guidelines and directives thereunder or issued in connection therewith and all requests,
rules, guidelines or directives promulgated by the Bank for International Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United States or foreign regulatory authorities, in each case pursuant
to Basel III, shall be deemed to have been adopted and gone into effect after the date hereof regardless of when adopted, enacted or issued.” 
 (r) By deleting the words and numbers “five percent (5.0%)” appearing in the fourth (4th) line of §4.12 of the Credit Agreement, and inserting in lieu thereof the words and numbers “four
percent (4.0%)”. 
 (s) By deleting in its entirety §4.15 of the Credit Agreement, and inserting in lieu thereof the
following: 
 “§4.15 Certain Provisions Relating to Increased Costs. If a Lender gives notice of the existence
of the circumstances set forth in §4.7 or any Lender requests compensation for any losses or costs to be reimbursed pursuant to any one or more of the provisions of §4.4(b) (as a result of the imposition of U.S. withholding taxes on
amounts paid to such Lender under this Agreement), §4.9 or §4.10, then, upon request of Borrower, such Lender, as applicable, shall use reasonable efforts in a manner consistent with such institution’s practice in connection with
loans like the Loan of such Lender to eliminate, mitigate or reduce amounts that would otherwise be payable by Borrower under the foregoing provisions, provided that such action would not be otherwise prejudicial to such Lender, including, without
limitation, by designating another of such Lender’s offices, branches or affiliates; the Borrower agreeing to pay all reasonably incurred costs and expenses incurred by such Lender in connection with any such action. Notwithstanding anything to
the contrary contained herein, if no Default or Event of Default shall have occurred and be continuing, and if any Lender has given notice of the existence of the circumstances set forth in §4.7 or has requested payment or compensation for any
losses or costs to be reimbursed pursuant to any one or more of the provisions of §4.4(b) (as a result of the imposition of U.S. withholding taxes on amounts paid to such Lender under this Agreement), §4.9 or §4.10 and following the
request of Borrower has been unable to take the steps described above to mitigate such amounts (each, an “Affected Lender”), then, within thirty (30) days after such notice or request for payment or compensation, as applicable,
Borrower shall have the one-time right as to such Affected Lender to be exercised by delivery of written notice delivered to the Agent 

  
 17 









 
and the Affected Lender within thirty (30) days of receipt of such notice, to elect to cause the Affected Lender to transfer its Commitment. The Agent shall promptly notify the remaining
Lenders that each of such Lenders shall have the right, but not the obligation, to acquire a portion of the Commitment, pro rata based upon their relevant Commitment Percentages, of the Affected Lender (or if any of such Lenders does not elect to
purchase its pro rata share, then to such remaining Lenders in such proportion as approved by the Agent). In the event that the Lenders do not elect to acquire all of the Affected Lender’s Commitment, then the Agent, in consultation with the
Borrower, shall endeavor to obtain a new Lender to acquire such remaining Commitment. Upon any such purchase of the Commitment of the Affected Lender, the Affected Lender’s interest in the Obligations and its rights hereunder and under the Loan
Documents shall terminate at the date of purchase, and the Affected Lender shall promptly execute all documents reasonably requested to surrender and transfer such interest. The purchase price for the Affected Lender’s Commitment shall equal
any and all amounts outstanding and owed by Borrower to the Affected Lender, including principal, prepayment premium or fee, and all accrued and unpaid interest or fees.” 
 (t) By inserting the following as new §5.2(c) and (d) of the Credit Agreement: 
 “(c) Notwithstanding the terms of §5.2(a), from and after any date that Agent first receives written notice from REIT or Borrower that Borrower has first obtained an Investment Grade Rating,
then (i) subject to the terms of this §5.2(c), Material Subsidiaries (including, without limitation, any Subsidiary Guarantor that is a direct or indirect owner of an Unencumbered Property) shall no longer be required to be Guarantors
under the Credit Agreement, and (ii) Agent shall promptly release the Material Subsidiaries from the Guaranty; provided however that notwithstanding the foregoing, (A) Agent shall not be obligated to release any Material Subsidiary from
the Guaranty in the event that a Default or Event of Default shall have occurred and be continuing, and (B) no Material Subsidiary shall be released in the event that such Material Subsidiary constitutes a Material Subsidiary within the meaning
of clause (b) of the definition thereof. In the event that at any time after Borrower has an Investment Grade Rating, Borrower shall no longer have an Investment Grade Rating, Borrower and REIT shall within thirty (30) days (or such later
date as agreed to by Agent) after such occurrence cause all Material Subsidiaries to execute the Guaranty in the form of the original Guaranty and cause such Material Subsidiaries, REIT and Borrower to execute a Contribution Agreement in the form of
the original Contribution Agreement, in each case with such conforming changes (i.e., references to dates of documents and parties) as Agent may reasonably require and shall further cause to be satisfied within such thirty (30) day
period (or such longer period as agreed to by Agent) all of the provisions of §5.2(a) that would be applicable to the addition of a new Guarantor. In no event shall the provisions of this §5.2(c) entitle REIT to be released from the
Guaranty. If at any time during which the Borrower has an Investment Grade Rating the provisions of clause (b) of the definition of Material Subsidiary shall be applicable to a Subsidiary of Borrower, the Borrower shall be required to cause
such Subsidiary to become a Guarantor by executing a Guaranty in the form of the original Guaranty and cause such Material Subsidiaries, REIT and Borrower to execute a Contribution Agreement in the form of the original Contribution Agreement, in
each case with such conforming changes (i.e., 

  
 18 









 
references to dates of documents and parties) as Agent may reasonably require and comply with the provisions of §5.2(a) as a condition to such Subsidiary’s becoming a guarantor or other
obligor with respect to such other Unsecured Debt regardless of whether Borrower has obtained an Investment Grade Rating. 
 (d) Notwithstanding anything to the contrary contained herein, in the event that the entities described in clause (a) of the definition of Material Subsidiary are not required to be a Subsidiary
Guarantor pursuant to §5.2(c), then the Unencumbered Properties owned by such Persons shall still be considered Unencumbered Properties for the purposes of this Agreement (and considered in the calculation of Unencumbered Asset Value and
Unencumbered Property Debt Yield) provided that the representations and warranties described below in this §5.2(d) with respect to such Persons continue to be true and correct in all material respects, and the Borrower and such Persons continue
to comply with the provisions and covenants (or such provisions and covenants shall be applicable to such Persons and shall be complied with, as applicable) described below in this §5.2(d), in each case, as and to the same extent as if such
Persons were Subsidiary Guarantors: 
 clause (d) of the definition of Change of Control; clause (b) of the definition
of Material Adverse Effect; definition of Non-Recourse Indebtedness; definition of Rent Roll; definition of Unencumbered Asset Value; §2.7; §2.10(b); §6.1(b); §6.16; §6.19; §6.20(a), (b), (c), (e) and (f); last
sentence of §6.21; §6.23; §6.26; §6.27; §6.28; §6.31; §7.4(l); §7.5(e); last sentence of §7.6(a); §7.6(b); §7.17 (for the purposes of §7.17, each entity that is a Material Subsidiary
pursuant to clause (a) of the definition of Material Subsidiary shall be required to make Distributions the same as other Subsidiaries who are not Subsidiary Guarantors); §7.22; last paragraph of §8.1; §8.2(iii); §8.4(v);
§8.6; §8.14; and §27.” 
 (u) By deleting the words “each calendar quarter”
appearing in the second (2nd) line of §7.4(b) of
the Credit Agreement, and inserting in lieu thereof the words “each of the first three (3) calendar quarters”; 

(v) By deleting in its entirety §8.1(f) of the Credit Agreement, and inserting the following in lieu thereof: 

“(f) subject to the provisions of §9, (i) Secured Debt of the Borrower and its Subsidiaries that is
Recourse Indebtedness, provided that the aggregate amount of such Indebtedness shall not exceed fifteen percent (15%) of Gross Asset Value, and (ii) Secured Debt of the Borrower and its Subsidiaries, provided that the
aggregate amount of such Indebtedness shall not exceed forty percent (40%) of Gross Asset Value. Notwithstanding the terms of this §8.1(f), Borrower may exceed such thresholds solely in connection with the refinancing of the indebtedness
of Fox Properties LLC to the lenders under the Fox Credit Agreement secured by the Fox Property to the extent the amount refinanced causes Borrower to exceed such limit solely as a result of Borrower including in such financing all accrued and
unpaid interest, premium and fees due and payable under the Fox Credit Agreement and reasonable closing fees and costs;” 

  
 19 









 (w) By deleting in its entirety §8.9 of the Credit Agreement and inserting in lieu
thereof “§8.9 Intentionally Omitted”. 
 (x) By deleting in its entirety §9.4 of the Credit Agreement, and
inserting in lieu thereof the following: 
 “§9.4 Minimum Consolidated Tangible Net Worth. The
Borrower will not at any time permit Borrower’s Consolidated Tangible Net Worth to be less than the sum of (i) $1,300,000,000.00, plus (ii) eighty percent (80%) of the sum of (A) any additional Net Offering Proceeds after
the Second Amendment Date, plus (B) the value of interests in Borrower or interests in REIT issued upon the contribution of assets to Borrower or its Subsidiaries after the Second Amendment Date (with such value determined at the time of
contribution).” 
 (y) By deleting the sentence in the last paragraph of §12.1 of the Credit Agreement which begins
with the words “In the alternative”, and inserting in lieu thereof the following: 
 “In the
alternative, if demanded by Agent in its absolute and sole discretion after the occurrence of an Event of Default, Borrower will deposit in the Collateral Account and pledge to Agent cash in an amount equal to the amount of all undrawn Letters of
Credit.” 
 (z) By inserting the following as new §12.6 of the Credit Agreement: 

“§12.6 Collateral Account. 

(a) As collateral security for the prompt payment in full when due of all Letter of Credit Liabilities, Swing Loans and
the other Obligations, the Borrower hereby pledges and grants to the Agent, for the ratable benefit of the Agent and the Lenders as provided herein, a security interest in all of its right, title and interest in and to the Collateral Account and the
balances from time to time in the Collateral Account. The balances from time to time in the Collateral Account shall not constitute payment of any Letter of Credit Liabilities or Swing Loans until applied by the Agent as provided herein. Anything in
this Agreement to the contrary notwithstanding, funds held in the Collateral Account shall be subject to withdrawal only as provided in this section and as otherwise provided in this Agreement. 

(b) If a drawing pursuant to any Letter of Credit occurs on or prior to the expiration date of such Letter of Credit, the
Borrower and the Lenders authorize the Agent to use the monies deposited in the Collateral Account to make payment to the beneficiary with respect to such drawing or the payee with respect to such presentment. If a Swing Loan is not refinanced as a
Base Rate Loan as provided in §2.5 above, then the Agent is authorized to use monies deposited in the Collateral Account to make payment to the Swing Loan Lender with respect to any participation not funded by a Defaulting Lender. 

  
 20 









 (c) If an Event of Default exists, the Required Lenders may, in their
discretion, at any time and from time to time, instruct the Agent to apply the funds in the Collateral Account to the Obligations in accordance with §12.5. 
 (d) So long as no Default or Event of Default exists, and to the extent amounts on deposit in the Collateral Account pursuant to §2.13(e) exceed the pro rata share of any Letter of Credit Obligations
and participations in Swing Loans of any Defaulting Lender after giving effect to §2.13(c), the Agent shall, from time to time, at the request of the Borrower, deliver to the Borrower within five (5) Business Days after the Agent’s
receipt of such request from the Borrower, against receipt but without any recourse, warranty or representation whatsoever, such excess balances in the Collateral Account at such time from deposits pursuant to §2.13(e). 

(e) The Borrower shall pay to the Agent from time to time such reasonable fees as the Agent normally charges for similar
services in connection with the Agent’s administration of the Collateral Account. The Borrower authorizes Agent to file such financing statements as Agent may reasonably require in order to perfect Agent’s security interest in the
Collateral Account, and Borrower shall promptly upon demand execute and deliver to Agent such other documents as Agent may reasonably request to evidence its security interest in the Collateral Account. 

(f) Upon indefeasible payment in full of all Obligations (other than indemnification obligations which by their terms
expressly survive payment of the Obligations and termination of this Agreement or any of the other Loan Documents unless a claim is pending with respect thereto) and the termination of the obligations of the Lenders and the Issuing Lenders to extend
credit hereunder and under the other Loan Documents and the cancelation or expiration of all Letters of Credit, all funds held in the Collateral Account shall be promptly returned to the Borrower and the security interest granted to Agent pursuant
to §12.6(a) shall automatically be released without any further action by any further party. Agent will, at Borrower’s expense, promptly execute and deliver to Borrower such documents as Borrower may reasonably request to evidence the

(cc) By deleting in its entirety §14.5(c) of the Credit Agreement; 

(dd) By deleting in its entirety §18.1 of the Credit Agreement, and inserting in lieu thereof the following: 

“§18.1 Conditions to Assignment by Lenders. Except as provided herein, each Lender may assign to one or
more banks or other entities all or a portion of its interests, rights and obligations under this Agreement (including all or a portion of its Commitment Percentage and Commitment and the same portion of the Loans at the time owing to it and the
Notes held by it); provided that (a) the Agent, the Issuing Lender and, so long as no Default or Event of Default exists hereunder, Borrower shall have each given its prior written consent to such assignment, which consent shall not be
unreasonably withheld or delayed (provided that such consent shall not be required for any assignment to another Lender, to a lender or an Affiliate of a Lender which controls, is controlled by or is under common control with the assigning Lender or
to a wholly-owned Subsidiary of such Lender), (b) each such assignment shall be of a constant, and not a varying, percentage of all the assigning Lender’s rights and obligations under this Agreement with respect to its Commitment,
(c) the parties to such assignment shall execute and deliver to the Agent, for recording in the Register (as hereinafter defined) an Assignment and Acceptance Agreement in the form of Exhibit H annexed hereto, together with any
Notes subject to such assignment, (d) in no event shall any assignment be to any Person controlling, controlled by or under common control with, or which is not otherwise free from influence or control by, Borrower, any Guarantor or REIT, or to
a Defaulting Lender or an Affiliate of a Defaulting Lender, (e) such assignee shall have a net worth as of the date of such assignment of not less than $100,000,000.00 (unless otherwise approved by Agent and, so long as no Default or Event of
Default exists hereunder, Borrower), (f) such assignee shall acquire an interest in the Loans of not less than $5,000,000.00 and integral multiples of $1,000,000.00 in excess thereof (or if less, the remaining Loans of the assignor), unless
waived by the Agent, and so long as no Default or Event of Default exists hereunder, Borrower, and (g) such assignee shall be subject to the terms of any intercreditor agreement among the Lenders and the Agent. Upon execution, delivery,
acceptance and recording of such Assignment and Acceptance Agreement, (i) the assignee thereunder shall be a party hereto and all other Loan Documents executed by the Lenders and, to the extent provided in such Assignment and Acceptance
Agreement, have the rights and obligations of a Lender hereunder, (ii) the assigning Lender shall, upon payment to the Agent of the registration fee referred to in §18.2, be released from its obligations under this Agreement arising after
the effective date of such assignment with respect to the assigned portion of its interests, rights and obligations under this Agreement, and (iii) the Agent may unilaterally amend Schedule 1.1 to reflect such assignment. In
connection with each assignment, the assignee shall represent and warrant to the Agent, the assignor and each other Lender as to whether such assignee is controlling, controlled by, under common control with or is not otherwise free from influence
or control by, the Borrower, any Guarantor and REIT and whether such 

  
 22 









 
assignee is a Defaulting Lender or an Affiliate of a Defaulting Lender. In connection with any assignment of rights and obligations of any Defaulting Lender, no such assignment shall be effective
unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be
outright payment, purchases by the assignee of participations or actions, including funding, with the consent of the Borrower and the Agent, the applicable pro rata share of Revolving Credit Loans previously requested but not funded by the
Defaulting Lender to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Agent or any Lender hereunder (and interest
accrued thereon) and (y) acquire (and fund as appropriate) its full pro rata share of all Revolving Credit Loans and participations in Letters of Credit and Swing Loans in accordance with its Commitment Percentage. Notwithstanding the
foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under applicable law without compliance with the provisions of this paragraph, then the assignee of such interest shall
be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.” 
 (ee) By deleting
in its entirety clause (f) of §18.4 of the Credit Agreement, and inserting in lieu thereof the following: 
 “(f) such participant shall not be a Person controlling, controlled by or under common control with, or which is not otherwise free from influence or control by the Borrower, any Guarantor or
REIT and shall not be a Defaulting Lender or an Affiliate of a Defaulting Lender;” 
 (ff) By inserting the following at
the end of §27 of the Credit Agreement, as part of §27. 
 “Notwithstanding anything to the
contrary herein, no Defaulting Lender shall have any right to approve or disapprove any amendment, waiver or consent hereunder (and any amendment, waiver or consent which by its terms requires the consent of all Lenders or each affected Lender may
be effected with the consent of the applicable Lenders other than Defaulting Lenders, except that (x) the Commitment of any Defaulting Lender may not be increased without the consent of such Lender and (y) any waiver, amendment or
modification requiring the consent of all Lenders or each affected Lender that by its terms affects any Defaulting Lender disproportionately adversely relative to other affected Lenders shall require the consent of such Defaulting Lender).”

 (gg) By deleting in its entirety the Appendix to the Compliance Certificate included in Exhibit G to the Credit Agreement,
and inserting in lieu thereof the Appendix to Compliance Certificate attached to this Amendment. 
 (hh) By inserting the words
“and is not a Defaulting Lender or an Affiliate of a Defaulting Lender,” at the end of clause (f) of Paragraph 4 of the Assignment and Acceptance Agreement attached to the Credit Agreement as Exhibit H; 

  
 23 









 (ii) By deleting in its entirety Schedule 1.1 of the Credit Agreement and inserting in lieu
thereof Schedule 1.1 attached to this Amendment. 
 3. Amendment to Guaranty. Guarantors, the Lenders and the Agent do
hereby modify and amend the Guaranty by deleting in its entirety Recital A appearing on page 1 of the Guaranty, and inserting in lieu thereof the following: 
 “A. On or about the date hereof, DuPont Fabros Technology, L.P., a Maryland limited partnership (“Borrower”), Agent and the Lenders entered into that certain Credit Agreement (as amended,
the “Credit Agreement”) whereby the Lenders agreed to make a revolving credit loan (the “Loan”) available to Borrower in the maximum aggregate amount at any time outstanding not to exceed the sum of $225,000,000.00,
increasable to Four Hundred Million and no/100 Dollars ($400,000,000.00). Capitalized terms used and not otherwise defined herein shall have the meanings given to them in the Credit Agreement.” 

4. Commitments. 
 (a) Borrower and Guarantors hereby acknowledge and agree that as of the effective date of this Amendment and following satisfaction of all conditions thereto as provided herein, the amount of each
Lender’s Commitment shall be the amount set forth on Schedule 1.1 attached hereto. In connection with the Increase, each of Barclays Bank PLC, RBS Citizens, N.A. and Stifel Bank & Trust (each individually a “New Lender” and
collectively, the “New Lenders”) shall be issued a Revolving Credit Note in the principal face amount of its Commitment, which will be a “Revolving Credit Note” under the Credit Agreement, and each New Lender shall be a Lender
under the Credit Agreement. 
 (b) Borrower and Guarantors hereby acknowledge and agree that as of the effective date of this
Amendment and following satisfaction of all conditions thereto as provided herein, the Swing Loan Commitment shall be increased from $25,000,000.00 to $35,000,000.00. In connection with the increase of the Swing Loan Commitment, KeyBank shall be
issued a replacement Swing Loan Note in the principal face amount of $35,000,000.00 (the “Replacement Swing Loan Note”), and upon acceptance of the Replacement Swing Loan Note by KeyBank it will be the “Swing Loan Note”
under the Credit Agreement. KeyBank will promptly return to Borrower the existing Swing Loan Note in the principal face amount of $25,000,000.00 marked “Replaced”. 
 (c) By its signature below, each New Lender, subject to the terms and conditions hereof, hereby agrees to perform all obligations with respect to its respective Commitment as if such New Lender were an
original Lender under and signatory to the Credit Agreement having a Commitment, as set forth above, equal to its respective Commitment, which obligations shall include, but shall not be limited to, the obligation to make Revolving Credit Loans to
the Borrower with respect to its Commitment as required under §2.1 of the Credit Agreement, the obligation to pay amounts due in respect of Swing Loans as set forth in §2.5 of the Credit Agreement, the obligation to pay amounts due in
respect of draws under Letters of Credit as required under §2.10 of the Credit Agreement, and in any case the obligation to indemnify the Agent as provided therein. Each New Lender makes and confirms to the Agent and the other Lenders all of
the representations, warranties and covenants of a Lender under Section 14 of the Credit Agreement. Further, each New Lender acknowledges that it has, 

  
 24 









 
independently and without reliance upon the Agent, or on any affiliate or subsidiary thereof or any other Lender and based on the financial statements supplied by the Borrower and such other
documents and information as it has deemed appropriate, made its own credit analysis and decision to become a Lender under the Credit Agreement. Except as expressly provided in the Credit Agreement, the Agent shall have no duty or responsibility
whatsoever, either initially or on a continuing basis, to provide any New Lender with any credit or other information with respect to the Borrower or Guarantors or to notify any New Lender of any Default or Event of Default. No New Lender has relied
on the Agent as to any legal or factual matter in connection therewith or in connection with the transactions contemplated thereunder. Each New Lender (i) represents and warrants as to itself that it is legally authorized to, and has full power
and authority to, enter into this agreement and perform its obligations under this agreement; (2) confirms that it has received copies of such documents and information as it has deemed appropriate to make its own credit analysis and decision
to enter into this agreement; (3) agrees that it has and will, independently and without reliance upon any Lender or the Agent and based upon such documents and information as it shall deem appropriate at the time, continue to make its own
credit decisions in evaluating the Revolving Credit Loans, the Loan Documents, the creditworthiness of the Borrower and the Guarantors and the value of the assets of the Borrower and the Guarantors, and taking or not taking action under the Loan
Documents; (4) appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such powers as are reasonably incidental thereto pursuant to the terms of the Loan Documents; and (5) agrees that, by this
agreement, it has become a party to and will perform in accordance with their terms all the obligations which by the terms of the Loan Documents are required to be performed by it as a Lender. Each New Lender acknowledges and confirms that its
address for notices and Lending Office for Revolving Credit Loans are as set forth on the signature pages hereto. 
 5.
References to Credit Agreement and Guaranty. All references in the Loan Documents to the Credit Agreement or Guaranty shall be deemed a reference to the Credit Agreement or Guaranty, as the case may be, as modified and amended herein.

 6. Acknowledgment of Borrower and Guarantors. Borrower and Guarantors hereby acknowledge, represent and agree that the
Loan Documents, as modified and amended herein, remain in full force and effect and constitute the valid and legally binding obligation of Borrower and Guarantors, as applicable, enforceable against Borrower and Guarantors in accordance with their
respective terms, and that the execution and delivery of this Amendment does not constitute, and shall not be deemed to constitute, a release, waiver or satisfaction of Borrower’s or any Guarantor’s obligations under the Loan Documents.

 7. Representations and Warranties. Borrower and Guarantors represent and warrant to Agent and the Lenders as follows:

 (a) Authorization. The execution, delivery and performance of this Amendment and the transactions contemplated hereby
(i) are within the authority of Borrower and Guarantors, (ii) have been duly authorized by all necessary proceedings on the part of the Borrower and Guarantors, (iii) do not and will not conflict with or result in any breach or

and will not conflict with or constitute a default (whether with the passage of time or the giving of notice, or both) under any provision of the partnership agreement or certificate, certificate of formation, operating agreement, articles of


  
 25 









 
incorporation or other charter documents or bylaws of, or any mortgage, indenture, agreement, contract or other instrument binding upon, any of the Borrower or Guarantors or any of their
respective properties or to which any of the Borrower or Guarantors is subject, and (v) do not and will not result in or require the imposition of any lien or other encumbrance on any of the properties, assets or rights of any of the Borrower
or Guarantors. 
 (b) Enforceability. The execution and delivery of this Amendment are valid and legally binding
obligations of Borrower and Guarantors enforceable in accordance with the respective terms and provisions hereof, except as enforceability is limited by bankruptcy, insolvency, reorganization, moratorium or other laws relating to or affecting

 (c) Approvals. The
execution, delivery and performance of this Amendment and the transactions contemplated hereby do not require the approval or consent of any Person or the authorization, consent, approval of or any license or permit issued by, or any filing or

Amendment. 
 (d) Reaffirmation. Borrower and Guarantors reaffirm and restate as of the date hereof each and every
representation and warranty made by the Borrower and Guarantors and their respective Subsidiaries in the Loan Documents or otherwise made by or on behalf of such Persons in connection therewith except for representations or warranties that expressly
relate to an earlier date. 
 8. No Default. By execution hereof, the Borrower and Guarantors certify that as of the date
of this Amendment and immediately after giving effect to this Amendment, no Default or Event of Default has occurred and is continuing.

whatsoever arising on or before the date hereof with respect to the Loan Documents, the administration or funding of the Loan or with respect to any acts or omissions of Agent or any Lender, or any past or present officers, agents or employees of
Agent or any Lender pursuant to or relating to the Loan Documents, and each of such Persons does hereby expressly waive, release and relinquish any and all such defenses, setoffs, claims, counterclaims and causes of action arising on or before the
date hereof, if any. 
 10. Ratification. Except as hereinabove set forth, all terms, covenants and provisions of the
Credit Agreement and Guaranty remain unaltered and in full force and effect, and the parties hereto do hereby expressly ratify and confirm the Loan Documents as modified and amended herein. Guarantors hereby consent to the terms of this Amendment.
Nothing in this Amendment or any other document delivered in connection herewith shall be deemed or construed to constitute, and there has not otherwise occurred, a novation, cancellation, satisfaction, release, extinguishment or substitution of the
indebtedness evidenced by the Notes or the other obligations of Borrower and Guarantors under the Loan Documents. 

  
 26
