BLACKSTONE MORTGAGE TRUST, INC.

Evaluation of Disclosure Controls and Procedures

The company maintains disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) under

the Exchange Act) that are designed to ensure that information required to be disclosed in the company’s reports under the

Exchange Act is recorded, processed, and summarized and reported within the time periods specified in the SEC’s rules

and forms, and that such information is accumulated and communicated to the company’s management, including its Chief

Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures.

Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of

achieving the desired control objectives. An evaluation of the effectiveness of the design and operation of our disclosure

controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q was made under the

supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial

Officer. Based upon this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our

disclosure controls and procedures (a) are effective to ensure that information required to be disclosed by us in reports filed

or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified by

SEC rules and forms and (b) include, without limitation, controls and procedures designed to ensure that information

required to be disclosed by us in reports filed or submitted under the Exchange Act is accumulated and communicated to

our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely

decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There have been no changes in our “internal control over financial reporting” (as defined in Rule 13a–15(f) of the

Exchange Act) that occurred during our most recent quarter that have materially affected, or are reasonably likely to

materially affect, our internal control over financial reporting.
