Optibase Ltd. (NASDAQ:OBAS), a leader in advanced digital video solutions, announced today that RiskMetrics Group (formerly, Institutional Shareholder Services) (ISS) issued a report recommending that shareholders of Scopus Video Networks Ltd. vote in favor of Optibase proposals to declassify the board of directors of Scopus and to elect a slate of directors, and against the proposal of Scopus' board of directors. ISS concluded that there is no compelling reason why Scopus shareholders should not be allowed to immediately vote on the entire board.

Scopus meeting is scheduled to be held on Monday, June 16, 2008. Shareholders of record at the close of business on May 9, 2008 will be entitled to vote at the meeting.

On May 19, 2008, Optibase issued an open letter to Scopus' shareholders. A copy of such letter is available at www.optibase.com/scopusvote/.

Scopus shareholders are urged to vote "AGAINST" proposal 1 (the proposal of Scopus' board of directors) and "FOR" proposal 2 and proposal 3 (Optibase proposals).

Scopus shareholders should review carefully the documents filed by either Optibase or Scopus with the Securities and Exchange Commission relating to Optibase's proposals, because they contain important information about the proposals and the forthcoming general meeting of Scopus shareholders. Copies of the documents filed with the Securities and Exchange Commission by either Optibase or Scopus may be obtained free of charge from the SEC website maintained at www.sec.gov.
