 THIS AMENDMENT NO. 2 TO NOTE PURCHASE AND PRIVATE SHELF AGREEMENT (this
“Amendment”) is entered into between Digital Realty Trust, L.P. (the “Company”), on the one hand, and Prudential Investment Management, Inc. (“PIM”) and the other Purchasers
party to the Note Agreement referred to below, on the other hand. 
 PRELIMINARY STATEMENTS: 

(1) The Company, Digital Realty Trust, Inc. (the “Parent Guarantor”), the subsidiaries of the Company party
thereto and the Purchasers from time to time party thereto have entered into a Note Purchase and Private Shelf Agreement, dated as of July 24, 2008, as amended by Amendment No. 1 to Note Purchase and Private Shelf Agreement dated as of
June 30, 2010 (collectively, and as further amended, supplemented or otherwise modified from time to time, the “Note Agreement”). Capitalized terms not otherwise defined in this Amendment have the same meanings as
specified in the Note Agreement. 
 (2) The Company and the Required Holders have agreed to amend the Note Agreement on the
terms and subject to the conditions hereinafter set forth. 
 SECTION 1. Amendment to Note Agreement. The Note Agreement
is hereby amended to delete the term “$175,000,000” set forth in Section 1B and to replace such term with “$225,000,000”. The undersigned parties acknowledge that, after giving effect to this Amendment, the Available
Facility Amount will be $50,000,000. 
 SECTION 2. Representations and Warranties. The Company hereby represents and
warrants that the representations and warranties contained in each of the Transaction Documents are true and correct on and as of the Amendment Effective Date (defined below), before and after giving effect to this Amendment, as though made on and
as of such date (except for any such representation and warranty that, by its terms, refers to an earlier date, in which case such representation and warranty is true and correct as of such earlier date). 

SECTION 3. Conditions of Effectiveness. This Amendment shall become effective as of the first date (the “Amendment
Effective Date”) on which, and only if, each of the following conditions precedent shall have been satisfied: 
 (a) The Purchasers shall have received (i) counterparts of this Amendment executed by the parties hereto, and (ii) the consent attached hereto (the “Consent”) executed by
each of the Guarantors. 
 (b) The Company shall have paid to or as directed by PIM an amendment fee equal to
$6,250 in immediately available funds. 
 (c) The representations and warranties set forth in each of the
Transaction Documents shall be correct in all material respects on and as of the Amendment Effective Date, before and after giving effect to this Amendment, as though made on and as of such date (except for any such representation and warranty that,
by its terms, refers to a specific date other than the Amendment Effective Date, in which case such representation and warranty shall be true and correct as of such specific date). 







 (d) No event shall have occurred and be continuing, or shall result from
the effectiveness of this Amendment, that constitutes a Default. 
 The effectiveness of this Amendment is conditioned upon the
accuracy of the factual matters described herein. This Amendment is subject to the provisions of Section 18 of the Note Agreement. 
 SECTION 4. Reference to and Effect on the Transaction Documents. (a) On and after the effectiveness of this Amendment, each reference in the Note Agreement to “this Agreement”,
“hereunder”, “hereof” or words of like import referring to the Note Agreement, and each reference in each of the other Transaction Documents to the “Agreement”, “Note Agreement”, “thereunder”,
“thereof” or words of like import referring to the Note Agreement, shall mean and be a reference to the Note Agreement, as amended by this Amendment. 
 (b) The Note Agreement, as specifically amended by this Amendment, is and shall continue to be in full force and effect and is hereby in all respects ratified and confirmed. 

(c) The execution, delivery and effectiveness of this Amendment shall not operate as a waiver of any right, power or
remedy of any holder of a Note or PIM under any of the Transaction Documents, nor constitute a waiver of any provision of any of the Transaction Documents. 
 SECTION 5. Costs and Expenses. The Company agrees to pay on demand all reasonable out-of-pocket costs and expenses of PIM in connection with the preparation, execution, delivery and administration,
modification and amendment of this Amendment and the other instruments and documents to be delivered hereunder (including, without limitation, the reasonable fees and expenses of counsel for PIM) in accordance with the terms of Section 16 of
the Note Agreement. 
 SECTION 6. Execution in Counterparts. This Amendment may be executed in any number of counterparts
and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute but one and the same agreement. Delivery of an executed counterpart of a
signature page to this Amendment by facsimile or email shall be effective as delivery of a manually executed counterpart of this Amendment. 
 SECTION 7. Governing Law. This Amendment shall be governed by, and construed in accordance with, the laws of the State of New York.
