As previously disclosed in a press release on March 30, 2015 (the “Press Release”), New Senior Investment Group Inc. (the “Company”), through its wholly owned subsidiary (the “Purchaser”), completed on March 27, 2015 the acquisition of a portfolio of 17 private pay, independent living properties located across 10 states (collectively, the “Hawthorn Portfolio”) pursuant to a Purchase and Sale Agreement (the “Purchase Agreement”) entered into on December 21, 2014, by and among the Purchaser and the sellers named therein. Each of the sellers (collectively, the “Seller”) is an affiliate of Hawthorn Retirement Group LLC.

The purchase price for the acquisition was $435,000,000, plus associated debt prepayment penalties of $26,499,000. The purchase price was funded with mortgage financing of $326,815,000, and the remainder was funded with cash on hand.

Concurrently with the closing of the transactions contemplated by the Purchase Agreement, the Company entered into management agreements with subsidiaries of Holiday Acquisition Holdings LLC (“Holiday”) pursuant to which Holiday will manage the properties comprising the Hawthorn Portfolio for a fee equal to 5% of the properties’ effective gross income. Holiday is majority-owned by private equity funds managed by an affiliate of New Senior’s manager.
