The Company acquired the communities, personal property and other intangibles associated with the communities from Kentland.  In connection with these transactions, the Company assumed $52.6 million of existing debt, paid off $24.8 million of existing debt, issued $45.5 million of preferred OP units and paid $19.4 million in cash.  The pay-off of existing debt was financed largely by $22.9 million of new debt on five (5) of the Kentland communities and one other existing community which bears a weighted average interest rate of 3.02 percent and has a weighted average maturity of 3.1 years. The $52.6 million of assumed debt carries a weighted average interest rate and weighted average maturity of 5.66 percent and 4.8 years, respectively. The preferred OP units carry an annual yield of 5.10 percent for the first two years and 6.00 percent thereafter and are convertible into shares of the Company’s common stock at a conversion price of $41 per share.  The acquisition includes 191 manufactured homes and $3.5 millionof chattel notes collateralized by manufactured homes.  The 18 communities acquired are located in western Michigan and comprise 5,042 manufactured home sites and 281 recreational vehicle sites.

As of the date of this release, the Company’s assumption of $5.6 million of the $52.6 million of assumed debt related to two of the 18 Kentland communities is pending completion of the final documentation with the lender, which is expected within the next few days.

As previously announced, the transaction is expected to contribute $0.24 to $0.28 of FFO per fully diluted share/OP unit in its initial twelve months, excluding the effect of transaction costs and the equity issued earlier in the year to fund the cash required for the transaction. The equity issuance was previously included in the Company’s 2011 guidance.
