<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The 20 communities are located in five states:&#160; North Carolina (seven communities); South Carolina (five communities); Florida (four communities); Virginia (two communities) and Georgia (two communities). The 20 communities primarily offer independent and assisted living services which are paid by residents from their private resources.&#160; The 2,111 living units in these communities include 814 independent living apartments, 939 assisted living suites, 311 suites which offer specialized Alzheimer&#146;s care and 47 skilled nursing beds.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Fifteen of the 20 communities costing approximately $211.5 million are currently expected to be leased to a TRS of SNH and managed by Five Star under a long term management contract.&#160; These 15 communities are currently approximately 85% occupied and SNH expects it may realize increasing income as these communities continue to fill.&#160; The current cash flows, before capital expenditures, from the communities expected to be leased to the TRS is expected to produce initial cash flows to SNH equal to approximately 7% to 7.5% per annum of SNH&#146;s purchase price.&#160; The remaining five communities which will cost approximately $92.5 million and are currently 97% occupied, are expected to be leased to Five Star and added to one or more of the combination leases currently in effect between SNH and Five Star.&#160; The rent for the five communities to be leased to Five Star is expected to produce an initial yield on SNH&#146;s investment of approximately 8% per annum and may increase starting in 2013 based upon a percentage of the increases in gross revenues at these communities.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">SNH expects to fund this purchase by assuming approximately $79 million of mortgage loans and using cash on hand and drawings under its $550 million revolving credit facility which was largely undrawn before this transaction.</font></p>
