Optibase Ltd. (Nasdaq: OBAS), today announced in a press release that on August 7, 2009, it entered into a joint venture to acquire 49.5% of the beneficial interest in the office building located at 485 Lexington Avenue in Manhattan from a subsidiary of SL Green Realty Corp. (the “Seller”). Optibase and Gilmor USA LLC, an unrelated party, are each equal partners in the joint venture through Mazal 485 LLC. On August 7, 2009, Mazal 485 LLC executed a Sale-Purchase Agreement to acquire certain interests in the building.

485 Lexington Avenue has over 900,000 square feet of leasable area and more than half of that space is occupied by Citibank N.A. and Travelers Indemnity Company.

Mazal 485 LLC will pay the Seller a purchase price of approximately $20,790,000 (which shall be contributed in equal shares by Optibase and Gilmor) in exchange for 49.5% of the ownership of Green 485 JV LLC, a Delaware limited liability company that will own the entire beneficial interest in the building prior to the closing.

At Closing, Green 485 JV LLC will have existing debt to an affiliate of the Seller in the amount of $12,200,000 which shall become due in 2013.

Mazal 485 LLC paid an initial deposit of $7,500,000 into escrow in order to secure the payment of the purchase price under the Sale-Purchase Agreement.

Upon completion of the transaction, Mazal 485 LLC will also make an approximately $20,000,000 nonrecourse loan to the Seller which will mature on December 31 2020 and which shall be secured by a pledge by the Seller of an additional 49.5% interest in Green 485 JV LLC, with the Seller retaining an unencumbered 1% interest in Green 485 JV LLC. Mazal 485 LLC will also acquire an option to purchase such additional ownership interests which is exercisable until December 31, 2022, subject to certain limitations.

485 Lexington Avenue has existing nonrecourse mortgage financing in the principal amount of $450,000,000 serviced by Wachovia Bank. The transactions above are subject to certain conditions including the lender’s approval of the transfer of ownership in Green 485 JV LLC and the lender’s approval of substitute guarantors under the loan.

In this regard, Mr. Tom Wyler, the Executive Chairman and CEO of Optibase, who is deemed Optibase’s controlling shareholder together with certain other parties, may be required to provide limited guarantees and indemnities for exceptional events which may include, but not be limited to, fraud, bankruptcy, dissolution, reorganization and liquidation proceedings, prohibited transfers, and certain acts of misapplication and/or misappropriation, and will additionally enter into a reimbursement and indemnification agreement with Optibase and Gilmor USA LLC and its principles in order to allocate their maximum obligations for responsibility under these guarantees and indemnities (collectively, the “Wyler Undertakings”).

There is no assurance that the conditions precedent contemplated in the Sale-Purchase Agreement will be fulfilled or that the transaction will be consummated at such time or at all.

Tom Wyler, Chief Executive Officer of the Company commented “following the decision to diversify our business and enter the fixed income real estate sector we believe the current transaction is the right business opportunity for us to execute on this decision.” Tom Wyler added “We are excited about this particular transaction being our entry point into the fixed-income real estate sector in North America and we believe our shareholders would benefit from this in the long run.”

Optibase’s audit committee and board of directors approved the grant of the Wyler Undertakings, as a transaction whose sole purpose is to benefit Optibase in accordance with the Israeli law.

Under Section 1C of the Israeli Companies Regulations (Relieves for Transactions with Related Parties) of 2000, each shareholder that holds at least 1% of Optibase’s issued share capital or voting rights is entitled to object to the possible Wyler Undertakings pursuant to Section 1B(2); provided, however, that such objection has been submitted to Optibase within 14 days as of the date of this press release. If such objection is received by Optibase within such 14-day period, the possible grant by Mr. Wyler of the Wyler Undertakings as discussed above, will require shareholders’ approval by a special majority pursuant to Section 275 of the Israeli Companies Law of 1999.
