Mr. Nochi Dankner, Mrs. Shelly Dankner-Bergman, Mrs. Ruth Manor and Mr. Avraham Livnat may, by reason of their interests in, and relationships among them with respect to, IDB Holding, be deemed to control the corporations referred to in paragraphs (1) - (4) above:

Nochi Dankner (together with a private company controlled by him) and Shelly Dankner-Bergman owned as of December 31, 2003 approximately 39.1% and 15.7% respectively of the outstanding shares of, and control, Ganden Holdings Ltd.

("Ganden"), a private Israeli corporation which in turn owned as of December 31, 2003 approximately 31.02% of the outstanding shares of IDB Holding. Nochi Dankner and Shelly Dankner-Bergman, who are brother and sister, entered into a memorandum of understanding dated May 5, 2003 setting forth, among other things, agreements between them as to how they will vote their shares of Ganden Holdings at its shareholders' meetings, who will they appoint as directors of such corporation, and first refusal and tag along rights available to each one of them in connection with sales of shares of such corporation owned by the other.

Nochi Dankner is the Chairman of the Boards of Directors, and Shelly Dankner-Bergman is a director, of IDB Holding, IDB Development and DIC.

In addition, as of December 31, 2003, Mrs. Shelly Dankner-Bergman owned (through a private company which is wholly-owned by her) approximately 4.75% of the outstanding shares of IDB Holding.

Ruth Manor controls a private Israeli corporation which in turn controls Manor Investments - IDB Ltd. ("Manor"), a private Israeli corporation owning as of December 31, 2003 approximately 10.34% of the outstanding shares of IDB Holding. Ruth Manor's husband, Isaac Manor, and their son, Dori Manor, are directors of IDB Holding, IDB Development and DIC. Dori Manor is also a director of Elron.

Avraham Livnat controls a private Israeli corporation which owns all the outstanding shares of Avraham Livnat Investments (2002) Ltd. ("Livnat"), a private Israeli corporation owning as of December 31, 2003 approximately 10.34% of the outstanding shares of IDB Holding. Avraham Livnat's son, Zvi Livnat, is a director of IDB Holding, IDB Development and DIC.

Ganden, Manor and Livnat entered into a Shareholders Agreement dated May 23, 2002 (the "IDB Shareholders Agreement") with respect to their ownership of shares of IDB Holding, constituting in the aggregate approximately 51.7% of the outstanding shares of IDB Holding, for the purpose of maintaining and exercising control of IDB Holding as one single group of shareholders. The IDB Shareholders Agreement provides, among other things, that Ganden will be the manager of the group as long as Ganden and its permitted transferees will be the largest shareholder of IDB Holding among the parties to the IDB Shareholders Agreement; that the parties to the IDB Shareholders Agreement will vote together at shareholders' meetings of IDB Holding as shall be determined according to a certain mechanism set forth therein; and that they will exercise their voting power in IDB Holding for electing their designees as directors of IDB Holding and its direct and indirect subsidiaries and other investee companies. Other provisions of the IDB Shareholders Agreement relate, among other things, to proposed transactions in shares of IDB Holding by any party thereto, including (i) a limitation whereby no party may sell its shares of IDB Holding for a period of two years from May 19, 2003 other than to certain permitted transferees of such party, (ii) a right of "first opportunity" whereby any party wishing to sell any of its shares of IDB Holding, other than to certain permitted transferees of such party, must first offer such shares to the other parties, (iii) a "tag along" right whereby in case of sale of any shares of IDB Holding owned by the manager of the group, other than to certain permitted transferees thereof, the other parties may join such sale, (iv) a "drag along" right whereby in case of sale of all of the shares of IDB Holding owned by the manager of the group, it may obligate the other parties to sell all their shares of IDB Holding together with such sale by the manager of the group to the same purchaser, at the same time and on terms as set forth in the IDB Shareholders Agreement, (v) an obligation of any party to offer its shares of IDB Holding to the other parties upon certain changes in the control of such party, and (vi) a right of participation in future acquisitions of shares of IDB Holding whereby any party acquiring additional shares of IDB Holding from third parties must offer the other parties the opportunity to participate in such acquisition on a pro rata basis. No party may sell shares of IDB Holding to any purchaser (including permitted transferees of such party) unless such purchaser joins the IDB Shareholders Agreement and assumes the rights and obligations of the selling party thereunder with respect to the shares sold by it. The term of the IDB Shareholders Agreement is twenty years from May 19, 2003 which may be extended by agreement of all parties thereto, and may be terminated as to any party in certain circumstances as set forth therein.

Ganden, Manor and Livnat pledged their shares of IDB Holding to certain financial institutions as collateral for the repayment of certain loans in an aggregate principal amount of $219 million borrowed by Ganden, Manor and Livnat to finance part of the price which they paid for the shares of IDB Holding purchased by them. The scheduled repayment dates of these loans are spread over a period of 12 years ending in May 2015. The pledges will be in effect until the loans are fully repaid, and include, among other things, certain restrictions relating to the disposition of, and the exercise of the voting rights attached to, the pledged shares. The lenders may realize the pledges and also may accelerate the repayment dates of the loans, in several different events (some of which will not be considered for such purpose to have occurred if rectified as provided for in the agreements relating to the loans) including, among others, default by the borrowers in performing their obligations under the agreements relating to these loans; the occurrence of events that entitle a third party to accelerate the repayment of other debts of the borrowers, or certain debts of IDB Holding or any of several specified companies held by it; if the borrowers or IDB Holding or certain of its major subsidiaries enter into certain extraordinary transactions such as a merger or reorganization, or sale or acquisition of major assets, or resolve to be voluntarily wound up, without the lenders' consent; if any of such entities becomes subject to insolvency, receivership or certain other similar proceedings; if certain financial ratios with respect to IDB Holding, or a certain minimum ratio between the value of the collateral and the outstanding balance of the loans, are not met; if the shares of IDB Holding or certain of its major subsidiaries are delisted from trading on the Tel Aviv Stock Exchange; if the IDB Shareholders Agreement is amended without the lenders' consent, or the control of the borrowers is changed; and the occurrence of a material adverse change in the financial condition of IDB Holding, which in the lenders' opinion may jeopardize the repayment of the loans, or an adverse change in the financial condition of certain entities and persons controlling the borrowers, which in the lenders' opinion may jeopardize the payment of certain contingent financial liabilities of such entities and persons in connection with the loans.

By reason of the control of IDB Holding by Nochi Dankner, Shelly Dankner-Bergman, Ruth Manor and Avraham Livnat, and the relations among them, as set forth above, Nochi Dankner, Shelly Dankner-Bergman, Ruth Manor and Avraham Livnat may each be deemed beneficial owner of, and to share the power to vote and dispose of, the Issuer Common Stock owned directly by Elron.
