        HERZLIYA, Israel, November 7, 2007 – Optibase, Ltd. (NASDAQ:OBAS) a leader in advanced digital video solutions today announced financial results for the third quarter ended September 30, 2007

        Net loss for the quarter ended September 30, 2007, was $1.6 million or $0.12 per basic and fully diluted share, compared with a net loss of $1.2 million or $0.09 per basic and fully diluted share for the second quarter of 2007 and with a net loss of $589,000 or $0.04 per basic and fully diluted share for the third quarter of 2006.

        For the nine months ended September 30, 2007, revenues totaled $17.4 million, compared with $12.6 million for the same period in 2006. Net loss for the period was $3.3 million or $0.24 per basic and fully diluted share, compared to a net loss of $3 million or $0.22 per basic and fully diluted share for the nine months ended September 30, 2006.

        Amir Philips CFO of Optibase, said, “We have continued to make progress toward achieving our primary financial and strategic goals.

        “Also, there were several contract wins in enterprise, or non-telco markets, an area that represent a growing opportunity for Optibase, which we hope to report on in the future. These wins, including announced IPTV installations at Fort Leavenworth, Kansas and Vancouver Airport, are good examples of the adaptability of Optibase’s technology for use outside the traditional telco-TV market.

        “Notwithstanding our recent success in the enterprise arena, we are also making steady progress within the more traditional telco market outside of the United States / North America. Bharti Airtel, a carrier with service in 94 cities in India, chose Optibase’s MGW 5100 IPTV encoding platforms for its planned IPTV service offerings. Additionally, our strategy to partner with local systems integrators yielded an installation in Spain.

        “We further strengthened our executive suite as Yossi Aloni was named president of Optibase Inc. in the United States and Eli Sharon had joined the Company as vice president of research & development. Both Yossi and Eli have considerable experience in the video and broadcast markets, and we believe both will be great assets in taking Optibase to the next level,”

        He concluded, “We remain pleased with the progress we are making, both broadly and within the individual markets we serve. While our revenues were down on a sequential basis, we view Q2 as an anomaly given the high concentration of third-party equipment we sold and are encouraged by our growth as compared to the third quarter of 2006.”
