Independent Auditors’ Report

The Members

Chicago Data Center

We have audited the accompanying Historical Summary of Gross Income and Direct Operating Expenses (the Historical Summary) of the Chicago Data Center for the year ended December 31, 2013, and the related notes to the Historical Summary.

Management’s Responsibility for the Historical Summary

Management is responsible for the presentation of the Historical Summary in accordance with U.S. generally accepted accounting principles; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of the Historical Summary that is free from material misstatement, whether due to fraud or error.

Auditors’ Responsibility

Our responsibility is to express an opinion on the Historical Summary based on our audit. We conducted our audit in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the Historical Summary is free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the Historical Summary. The procedures selected depend on the auditors’ judgment, including the assessment of the risks of material misstatement of the Historical Summary, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation and fair presentation of the Historical Summary in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the Historical Summary.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the Historical Summary referred to above presents fairly, in all material respects, the gross income and direct operating expenses of the Chicago Data Center for the year ended December 31, 2013, in accordance with U.S. generally accepted accounting principles.

Emphasis of Matter

We draw attention to Note 2 to the Historical Summary, which describes that the accompanying Historical Summary was prepared for the purpose of complying with the rules and regulations of the Securities and Exchange Commission, for inclusion in the filing of Form 8-K of Carter Validus Mission Critical REIT, Inc. and is not intended to be a complete presentation of the Chicago Data Center’s revenues and expenses. Our opinion is not modified with respect to this matter.

Notes to Historical Summary of Gross Income and Direct Operating Expenses

Three Months ended March 31, 2014 (Unaudited) and Year ended December 31, 2013

NOTE 1 – BUSINESS

On May 20, 2014, Carter Validus Mission Critical REIT, Inc. (the “Company”) acquired the Chicago Data Center, located in Northlake, Illinois (the “Property”). The Company acquired the Property through DC-505 North Railroad Avenue, LLC, an indirect wholly owned subsidiary. The purchase price for the Property was $211,700,000, exclusive of closing costs. The Company funded the acquisition of the Property with proceeds from the sale of its common stock.

The Property is a 251,141 square foot (unaudited) data center situated on approximately nineteen acres (unaudited), located at 505 North Railroad Avenue, Northlake, Illinois. The Property is approximately 60% leased to the following four tenants: Comcast Cable Communications Management, LLC, HSBC Technology & Services (USA) Inc., Trans Union, LLC and Walgreen Co.

NOTE 2 – BASIS OF PRESENTATION

The Historical Summary of Gross Income and Direct Operating Expenses (“Historical Summary”) has been prepared for the purpose of complying with the rules and regulations of the Securities and Exchange Commission (the “SEC”) and is not intended to be a complete presentation of the Property’s revenues and expenses. The Historical Summary has been prepared on the accrual basis of accounting and requires management of the Property to make estimates and assumptions that affect the reported amounts of the revenues and expenses during the reporting period. Actual results may differ from those estimates.

The unaudited Historical Summary for the three months ended March 31, 2014 has been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information. Accordingly, it does not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of the Company’s management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. The Historical Summary for the three months ended March 31, 2014 is not necessarily indicative of the expected results for the entire year ended December 31, 2014.

A Historical Summary is being presented for the most recent year available instead of the three most recent years based on the following factors: (1) the Property was acquired from an unaffiliated party; and (2) based on due diligence of the Property conducted by the Company, management is not aware of any material factors relating to the Property that would cause this financial information not to be indicative of future operating results.

Notes to Historical Summary of Gross Income and Direct Operating Expenses

Three Months ended March 31, 2014 (Unaudited) and Year ended December 31, 2013

NOTE 3 – GROSS INCOME

Although the leases provide for increases in minimum lease payments over the term of the lease, rental income accrues for the full period of occupancy on a straight-line basis. Related adjustments increased base rental income by $274,394 (unaudited) for the three months ended March 31, 2014 and increased base rental income by $881,846 for the year ended December 31, 2013.

Minimum base rents to be received from the Property’s four tenants under the operating leases in place as of December 31, 2013, are as follows:

NOTE 4 – DIRECT OPERATING EXPENSES

Direct operating expenses include only those expenses expected to be comparable to the proposed future operations of the Property. The Property’s leases are net leases, obligating the tenants to directly pay most of the Property’s direct operating expenses. Accordingly, the direct operating expenses for the three months ended March 31, 2014 and for the year ended December 31, 2013 only include utilities, property taxes, insurance, labor, repair and maintenance, and other miscellaneous operating expenses.

NOTE 5 – SUBSEQUENT EVENTS

Subsequent events were evaluated from March 31, 2014 through August 5, 2014, the date on which the Historical Summary was issued.
