Agreement termination description		The Agreement may be terminated by Orion (a) within 28 days from the date of execution (the “Contingency Period”), if during such period it objects to any fact, condition, requirement or exception set forth in the title reports, and (b) thereafter, if any contingency set forth in the Agreement is not satisfied by the Partnership by December 31, 2015, and in either case, Orion will be refunded its deposits. However, if after the Contingency Period the Partnership is in default, and Orion is not in default, in the performance of any of its representations, warranties or covenants under the Agreement, and Orion has satisfied all of its obligations, then Orion may either (i) terminate the Agreement and receive a refund of its deposits and also recover from the Partnership its reasonable out-of-pocket costs in connection with the Agreement (but not to exceed $50,000) as liquidated damages, or (ii) bring a suit for specific performance. If a contingency to the Partnership closing set forth in the Agreement is not satisfied by December 31, 2015, then the Partnership may terminate the Agreement and Orion will be refunded its deposits. However, if Orion is in default, and the Partnership is not in default, in the performance of any of its representations, warranties or covenants under the Agreement, and the Partnership has satisfied all of its obligations, then the Partnership may terminate the Agreement and receive Orion’s deposits as liquidated damages. Following completion of the transaction, the current leases on the Properties will be terminated and the General Partner will lease the Properties from Orion. The sale of the Properties pursuant to the terms and conditions of the Purchase and Sale Agreement is subject to approval of a majority interest of the limited partners of the Partnership and other customary closing conditions related to the sale of real property. If the transaction is consummated, CBRE, Inc., the real estate broker for the sale of the properties by the Partnership, will receive a commission of 1.5% of the purchase price. If the sale is approved by the majority interest of limited partners of the Partnership, the sale is expected to close during the fourth quarter of 2015.
