As previously reported in our Current Report on Form 8-K filed on August 8, 2012 (the “August 8, 2012 Form 8-K”), Landmark Apartment Trust of America, Inc. (f/k/a Apartment Trust of America, Inc.) (the “Company”) and Landmark Apartment Trust of America Holdings, LP (f/k/a Apartment Trust of America Holdings, LP), the Company’s operating partnership (the “Operating Partnership” and, together with the Company, the “LATA Parties”), entered into a master contribution and recapitalization agreement and a series of separate interest contribution agreements (the “Contribution Agreements”) to acquire a total of 21 multifamily apartment communities and one parcel of submerged land (the “Contributed Properties”), containing an aggregate of 6,079 units, in exchange for aggregate consideration valued at approximately $480.9 million (subject to customary prorations), including approximately $185.2 million (subject to adjustment based on prorations and principal amortization) in common units of limited partnership interest in the Operating Partnership (“Common Units”) valued at $8.15 per unit and approximately $14.0 million in cash, as well as the assumption by the LATA Parties of approximately $281.7 million of in-place mortgage indebtedness encumbering the Contributed Properties (based on principal amounts outstanding as of June 30, 2012). The acquisition of one of the Contributed Properties, known as Andros Isles Apartments, is subject to certain earnout provisions, whereby the Company is obligated to pay up to $4.0 million of additional consideration contingent upon satisfaction of certain net operating income levels for such property over a four-year period.

The Contribution Agreements, which were entered into on August 3, 2012, are subject to the satisfaction of various customary closing conditions, including the receipt of lender consents. Eighteen of the Contributed Properties were controlled or managed by Elco Landmark Residential Holdings LLC (“EL”) and/or Elco Landmark Residential Management LLC (“ELRM” and, together with EL, the “EL Companies”), or their affiliates, and three of the Contributed Properties were controlled or managed by DeBartolo Development, LLC and its affiliates (“DeBartolo”).

On August 3, 2012, the Company paid to the Company’s former advisor, ROC REIT Advisors, LLC an acquisition fee of $4.0 million in connection with the contribution of the Contributed Properties. ROC REIT Advisors, LLC is an affiliate of Stanley J. Olander, Jr., the Company’s chief executive officer, and Gustav G. Remppies, the Company’s president.

In connection with the acquisition by the Company of the Contributed Properties, ATA Property Management, LLC, a subsidiary of the Operating Partnership that provides property management services with respect to all of the Company’s properties as well as certain properties owned by third parties, will assume responsibility for managing each Contributed Property upon closing of such Contributed Property. ATA Property Management, LLC entered into a Management Support Services Agreement with ELRM pursuant to which ELRM will provide ATA Property Management, LLC with certain operational support services with respect to each Contributed Property upon closing of such Contributed Property. ELRM will be entitled to receive a fee equal to 3% of the gross receipts of each Contributed Property under the Management Support Services Agreement. ELRM is an affiliate of Joseph G. Lubeck, the Company’s executive chairman. ATA Property Management, LLC can terminate the Management Support Services Agreement with respect to any property on 30 days’ notice without penalty.

The mortgage indebtedness assumed is a variable interest rate loan issued by Wells Fargo Bank, N.A. maturing on April 9, 2013 (the “Wells Fargo Loan”). The interest rate on the Wells Fargo Loan is equal to one month LIBOR plus 3.75%; however, in no event will such interest rate be lower than 4.75%.

In evaluating the Overlook at Daytona Property as a potential acquisition and determining the appropriate amount of consideration to be paid, the Company considered a variety of factors, including property condition reports, tenant rent rolls, property location, visibility and access, age of the property, physical condition and curb appeal, review of an independent third-party appraisal, neighboring property uses, local market conditions, including vacancy rates, area demographics, including average household income, neighborhood growth patterns and economic conditions, and the presence of demand generators.

Seabreeze Daytona Marina

On August 28, 2012, the Company, pursuant to an Interest Contribution Agreement (the “Seabreeze Marina Agreement”) by and among the LATA Parties, ELRM and the persons and entities identified as the contributors on Schedule A of the Seabreeze Marina Agreement, acquired 100% of the interests in Seabreeze Daytona Marina, LLC, a Delaware limited liability company, which owns as its sole asset one of the Contributed Properties (the “Seabreeze Marina Property”), in exchange for 257,669 Common Units valued at $8.15 per unit for an aggregate consideration of approximately $2,100,000. The Seabreeze Marina Property consists of a submerged parcel of land in the Halifax River located in close proximity to the Overlook at Daytona Property. Additionally, the Seabreeze Marina Property serves as additional collateral for the Wells Fargo Loan, described above. The Company anticipates that it will construct a marina on the Seabreeze Marina Property in the future.

In evaluating the Seabreeze Marina Property as a potential acquisition and determining the appropriate amount of consideration to be paid, the Company considered a variety of factors, including property location and access, potential for future development as a marina and proximity to the Overlook at Daytona Property.

The approximately $9,375,000 of mortgage indebtedness was issued by CW Capital and Fannie Mae, bears interest at a rate of 2.93% and matures on September 1, 2019.

In evaluating the Bay Breeze Property as a potential acquisition and determining the appropriate amount of consideration to be paid, the Company considered a variety of factors, including property condition reports, tenant rent rolls, property location, visibility and access, age of the property, physical condition and curb appeal, review of an independent third-party appraisal, neighboring property uses, local market conditions, including vacancy rates, area demographics, including average household income, neighborhood growth patterns and economic conditions, and the presence of demand generators.

No additional compensation was paid to the Company’s former advisor or any other related party in connection with the acquisitions described above. Except as noted above, the Company currently has no additional plans for any renovations, improvements or development of the properties described herein. The Company believes the acquired properties are adequately insured. The acquisitions of 18 of the remaining 19 apartment communities pursuant to the Contribution Agreements are expected to close not later than the end of the fourth quarter of 2012. The Company anticipates completing the acquisition of the Andros Isles Apartments property in 2013.
