In deciding to acquire the Property, the following points were especially attractive. 1) Additional Acquisition As NBF already owns certain condominium interests in the Property (ratio of right to use land: 478,516/1,000,000; ratio of the registered exclusively owned area to the office building of the Property (= condominium interests): approx. 60.50%), the current additional acquisition will result in possession by NBF of condominium interests in the Property representing the ratio of right to use land of 720,886/1,000,000 and the ratio of the registered exclusively owned area to the office building of the Property (= condominium interests) of approximately 93.12%. Such acquisition is considered to be in line with NBF’s policy of increasing the asset value and liquidity of the Property. 2) Location The Naka-Meguro district, where the Property is located, lies within the western part of the Tokyo central business districts (consisting of Shinjuku, Shibuya, Ebisu, Meguro, etc.), an area which has seen remarkable growth especially with respect to the demand for office space for use by service, IT-related, and foreign capital companies and is surrounded by the residential area known as uptown Tokyo (Yamanote). Small to mid-size office buildings have previously been built along Yamate Street, but following the construction of the Property as a landmark directly in front of the train station, the area has become even more dynamic and exciting. One of the most notable features of the Naka-Meguro district is its pedestrian-friendly nature, made possible by ground-level access from the intersection of Yamate and Komazawa Streets, and direct underground access via private railway and subway lines to Shibuya, Roppongi, Kasumigaseki and Hibiya. The Property is situated next to Naka-Meguro Station, which offers inter-connected use of the Hibiya line of the Tokyo Metro system and the Toyoko line of the Tokyu rail system. This excellent pedestrian network is highly appreciated by the tenants of the Property from a business standpoint. 3) Building and Facilities The Property is located on a 1.2 hectare sector, the development of which was completed in March, 2002 as a part of the Kami-Meguro 2-chome Class One Urban Redevelopment Project. The Property, a high-rise, very intelligent office building, is the centerpiece of this sector and draws together various urban residential buildings, commercial and cultural facilities as well as public facilities to create a multi-functional development. The building has 25 above-ground floors, each with standard rental space of approximately 962 ㎡ featuring horizontally flowing windows on three sides of each floor creating a very bright and spacious environment. The office space has a ceiling height of 2,650mm with a 100mm sub-floor cavity for connection of OA equipment. Each floor can be divided into a maximum of four zones, and air conditioning can be set and adjusted for each zone outside normal business hours. Electrical capacity is 50VA/㎡. 3 Outline of Assets to be Acquired 1) Location 1-1, Kamimeguro 2-chome, Meguro-ku, Tokyo 2) Use Office 3) Type of Ownership and Equity (i) Land: ownership (ratio of right to use land (i) 138,415/1,000,000, (ii)103,955/1,000,000) (ii) Building: ownership ※The Property site includes an office building, residential building and building for shops, residences and public facilities.
