The information reported in Item 2.01 and Item 2.03 of this Current Report on Form 8-K is incorporated herein by reference.

On March 30, 2012, HC-2501 W William Cannon Dr, LLC (“HC-2501 Cannon”), a wholly owned subsidiary of Carter/Validus Operating Partnership, LP (“CVOP”), the operating partnership of the Carter Validus Mission Critical REIT, Inc. (the “Company”), acquired 100% of the fee simple interest in an approximately 27,000 square foot integrated medical facility consisting of a surgical center, a diagnostic and radiological center, and a pain management center (the “Stonegate Medical Center”), located in Austin, Texas, for a purchase price of $9,100,000, plus closing costs. The seller of the Stonegate Medical Center, Stonegate Professional Properties, L.P., is not affiliated with the Company, its advisor or its respective affiliates.

The Company purchased the Stonegate Medical Center using $9,100,000 of net proceeds from its initial public offering. In addition, at the time of acquisition, the Company placed a mortgage on the property, which allows the Company to borrow up to $4,890,000 under a secured line of credit. The terms of the line of credit are defined below. In connection with the acquisition, the Company paid an acquisition fee of approximately $182,000, or 2% of the purchase price, to the Company’s advisor, Carter/Validus Advisors, LLC.

The Stonegate Medical Center was constructed in 2008 and consists of three buildings. As of March 30, 2012, the Stonegate Medical Center was 100% leased to three tenants.

Substantially all of the operations at the Stonegate Medical Center are healthcare related. In evaluating the Stonegate Medical 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, 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.

The following table shows, as of March 30, 2012, the current effective annual rental income, lease expiration and renewal options for the three tenants that occupy 10% or more of the rentable square footage of the Stonegate Medical Center:

For 2011, the real estate taxes on the Stonegate Medical Center were approximately $99,100. For federal income tax purposes, the Company estimates that the depreciable basis in the Stonegate Medical Center will be approximately $7,180,000. For federal income tax purposes, the Company depreciates personal property and buildings based upon an estimated useful life of 7 and 39 years, respectively. The Stonegate Medical Center is located in Austin, Texas, and as such may compete with other healthcare properties for tenants if the tenant leases are not renewed.

On March 30, 2012, CVOP, and HC-2501 Cannon, entered into a credit agreement with Keybank National Association (“KeyBank”) to obtain a secured revolving credit facility in an aggregate maximum principal amount of $30,000,000 (the “KeyBank Line of Credit”). The KeyBank Line of Credit is evidenced by a promissory note in the principal amount of $30,000,000, a credit agreement, a guaranty agreement, a contribution agreement, and a hazardous materials indemnity agreement (collectively, the “KeyBank Loan Agreement”). The proceeds of loans made under the KeyBank Loan Agreement may be used to finance the purchase of properties, capital expenditures with respect to real estate and for general corporate working capital purposes. The initial term of the KeyBank Loan Agreement is 36 months from the closing date, maturing on March 30, 2015, which may be extended by one 12-month period subject to the satisfaction of certain conditions, including payment of an extension fee.

On March 30, 2012, the Company secured the KeyBank Line of Credit by executing a Deed of Trust, Assignment of Leases and Rents, and Security Agreement (the “KeyBank Deeds of Trust”) on our Stonegate Medical Center for the benefit of the lender. During the initial and the extended term of the KeyBank Loan Agreement, any loan made under the KeyBank Loan Agreement shall bear interest at per annum rates equal to either: (a) the London Interbank Offered Rate (“LIBOR”), plus an applicable margins ranging from 2.50% to 3.25% which are determined based on the overall leverage of CVOP or (b) a base rate which means, for any day, a fluctuating rate per annum equal to the prime rate for such day plus an applicable margin ranging from 1.25% to 2.00% which are determined based on the overall leverage of CVOP. In addition to interest, CVOP is required to pay a fee on the unused portion of the lenders’ commitments under the KeyBank Loan Agreement at a per annum rate equal to 0.50% if the average daily amount outstanding balance under the KeyBank Loan Agreement is less than 50% of the lenders’ commitments or 0.35% if the average daily amount outstanding under the KeyBank Loan Agreement is greater than 50% of the lenders’ commitments, and the unused fee is payable quarterly in arrears. In the event of a default, CVOP shall be required to pay a default interest rate equal to interest rate calculated in accordance with the KeyBank Loan Agreement plus 5.00% per annum. Additionally, in the event of default the lender has the right to terminate its obligations under the KeyBank Loan Agreement, including the funding of future loans, to accelerate the payment on any unpaid principal amount of all outstanding loans and interest thereon and may seek foreclosure on the Stonegate Medical Center or any other properties that are added to the collateral pool.

The actual amount of credit available under the KeyBank Line of Credit is a function of certain loan-to-cost, loan-to-value, debt yield and debt service coverage ratios contained in the KeyBank Loan Agreement. The initial credit available for CVOP to borrow under the KeyBank Loan Agreement will be a maximum principal amount of $4,890,000 and will increase if CVOP adds additional properties to the collateral pool to secure the KeyBank Line of Credit. Additional financial institutions are expected to become lenders under the KeyBank Loan Agreement and subject to certain conditions, the KeyBank Line of Credit can be increased up to $250,000,000. The obligations of CVOP and HC-2501 Cannon with respect to the KeyBank Loan Agreement are guaranteed by the Company, including but not limited to, the payment of any outstanding indebtedness under the KeyBank Loan Agreement and all terms, conditions and covenants of the KeyBank Loan Agreement, as further discussed below. In addition, CVOP has pledged a security interest in the Stonegate Medical Center as collateral for the KeyBank Line of Credit pursuant to the terms of the KeyBank Loan Agreement and through the KeyBank Deed of Trust. Furthermore, CVOP has assigned its rights under respective property management agreements and advisory agreements of HC-2501 Cannon as additional collateral to secure the KeyBank Line of Credit.

The KeyBank Loan Agreement contains various affirmative and negative covenants that are customary for credit facilities and transactions of this type, including limitations on the incurrence of debt by our operating partnership and its subsidiaries that own properties that serve as collateral for the KeyBank Line of Credit, limitations on the nature of CVOP’s business, and limitations on distributions by us, CVOP and its subsidiaries. The KeyBank Loan Agreement also imposes the following financial covenants, which are specifically defined in the KeyBank Loan Agreement, on us, CVOP and HC-2501 Cannon, as applicable: (a) minimum liquidity thresholds; (b) a minimum ratio of operating cash flow to fixed charges; (c) a maximum ratio of liabilities to asset value; (d) a maximum daily distribution covenant; (e) minimum quarterly equity raise; (f) minimum number of properties in the collateral pool; (g) minimum debt yield; and (h) a minimum tangible net worth. In addition, the KeyBank Loan Agreement includes events of default that are customary for credit facilities and transactions of this type.
