While Mr. Elsztain is the Reporting Person herein, Mr. Elsztain disclaims beneficial ownership of the Ordinary Shares reported by CIEH herein, primarily as a result of the following: On August 21, 2013, the Israeli Supervisor of Capital Markets, Insurance and Savings (the "Commissioner of Insurance") appointed Mr. Moshe Terry (the "Trustee") to hold, as trustee, IDB Development means of control in CIEH, including the voting power, except for 5% which remains held by IDB Development, and instructed IDB Development to dispose of its interest in CIEH.

All of the CIEH Shares are held for members of the public through, among others, provident funds and/or pension funds and/or insurance policies, which are managed by subsidiaries of CIEH[. Consequently, this Statement shall not be construed as an admission by Mr. Elsztain that he is the beneficial owner of any Ordinary Shares held by CIEH covered by this Statement.

All of the Epsilon Shares are held by portfolio management and/or mutual funds, which are managed by Epsilon Investment House Ltd. and/or Epsilon Mutual Funds Management (1991) Ltd... Consequently, this Statement shall not be construed as an admission by Mr. Elsztain that he is the beneficial owner of any Ordinary Shares held by Epsilon covered by this Statement.
