The information reported in Item 2.01 of this Current Report on Form 8-K is incorporated herein by reference.

On March 14, 2012, DC-2775 Northwoods Parkway, LLC (“DC-2775 Northwoods Parkway”), a wholly owned subsidiary of Carter/Validus Operating Partnership, LP (“CVOP”), the operating partnership of the Carter Validus Mission Critical REIT, Inc. (the “Company”), completed the acquisition of 100% of the fee simple interest in a 32,740 square foot data center (the “Northwoods Data Center”), located in the Atlanta, Georgia metropolitan area, for a purchase price of $5,300,000, plus closing costs. The seller of the Northwoods Data Center, 2775 Northwoods, LLC, is not affiliated with the Company, Carter/Validus Advisors, LLC, the Company’s advisor, or its respective affiliates.

The acquisition was funded by a $3,300,000 loan secured by a first priority interest in the Northwoods Data Center and net proceeds from the Company’s ongoing public offering. In connection with the acquisition, the Company paid an acquisition fee of approximately $106,000, or 2% of the purchase price, to its advisor. An affiliate of the Company’s advisor has been retained to manage, operate, lease and supervise the overall maintenance of the Northwoods Data Center and will receive a property management fee of 3.0% of the monthly revenue derived from the Northwoods Data Center. The Company currently has no plans for any renovations, improvements or further development of the Northwoods Data Center. The Company believes the Northwoods Data Center is adequately insured.

The Northwoods Data Center was constructed in 1986 as a data center, and in 2010 through 2012, the current sole tenant, Peak 10, Inc. (“Peak 10”), upgraded the property’s power capacity, expanded the raised floors and updated the heating ventilation and air conditioning units. The property is located on approximately three acres of land in the Atlanta, Georgia metropolitan area. As of March 14, 2012, the Northwoods Data Center was 100% leased to Peak 10. The Company believes the tenant is creditworthy based on its historical revenue and cash flow streams. All of the operations at the Northwoods Data Center and the principal nature of business of Peak 10 are data center related.

The following table shows, as of March 14, 2012, the current effective annual rental income, lease expiration and renewal options for the sole tenant of the Northwoods Data Center:

In evaluating the Northwoods Data Center as a potential acquisition and determining the appropriate amount of consideration to be paid for such acquisition, a variety of factors were considered, including the property condition and environmental reports, physical condition and curb appeal, age, location, including visibility and access, tenant creditworthiness, the operator of the facility, Peak 10, lease terms, including rent, rent increases, length of lease term, specific tenant and landlord responsibilities, renewal options, expansion, termination, purchase options, exclusive and permitted use provisions, assignment, sublease and co-tenancy provisions, local market conditions, demographics and population growth patterns, neighboring properties, the potential for new property construction in the area and whether there were any anticipated required capital improvements.

For 2011, the real estate taxes on the Northwoods Data Center were approximately $43,000. For federal income tax purposes, the Company estimates that the depreciable basis in the Northwoods Data Center will be approximately $4,800,000. For federal income tax purposes, the Company depreciates personal property and buildings based upon an estimated useful life of 7 and 39 years, respectively.

Loan Documents

On March 14, 2012, in connection with the acquisition of Northwoods Data Center, DC-2775 Northwoods Parkway entered into a deed to secure debt, assignment of rents and security agreement (the “Deed”) with, and executed a promissory note (collectively with the “Deed”, the “Loan Documents”) for the benefit of, American Family Life Insurance Company (“American Family”), to obtain a loan in the principal amount of $3,300,000 (the “Loan”), which is secured by a first priority interest in the Northwoods Data Center. The material terms of the Loan Documents provide for the following: (i) a fixed annual interest rate of 5.25%; (ii) a default interest rate equal to the lesser of (x) the maximum rate permitted by applicable law or (y) the greater of (a) 5.00% above the stated interest rate (5.25%) or (b) 5.00% above an annual rate equal to 325 basis points greater than the yield on U.S. Treasury securities with ten (10) years remaining to maturity; (iii) a maturity date of April 10, 2022; provided, however, that the Loan will become automatically due and payable at the option of American Family upon the happening of an event of default, as defined in the Loan Documents; and (iv) the Loan can be prepaid at any time subsequent to the fourth anniversary of the Loan subject to DC-2775 Northwoods Parkway’s obligation to pay a prepayment premium computed as a percentage of the principal prepaid, as provided in the Loan Documents. The Loan is assumable at any time by a proposed purchaser, subject to American Family’s consent, and a 1% assumption fee, as provided for in the Loan Document. The Loan Documents do not require DC-2775 Northwoods Parkway to escrow funds for capital reserves, taxes, or insurance. The Loan is non-recourse as to DC-2775 Northwoods Parkway and CVOP, but both entities are liable jointly and severally for customary non-recourse carve-outs. The Loan Documents also contain various affirmative and negative covenants that are customary for loan agreements and transactions of this type, including limitations on the incurrence of additional debt by DC-2775 Northwoods Parkway.
