ITEM 4. DESCRIPTION OF SECURITIES.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

Not applicable.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

Under the Israeli Companies Law, 5759-1999 (the “Israeli Companies Law”), a company may not exculpate an office holder from liability for a breach of the duty of loyalty. An Israeli company may exculpate an office holder in advance from liability to the company, in whole or in part, for damages caused to the company as a result of a breach of duty of care but only if a provision authorizing such exculpation is included in its articles of association. Our amended and restated articles of association include such a provision. An Israeli company may not exculpate a director from liability arising out of a prohibited dividend or distribution to shareholders.

An Israeli company may indemnify an office holder in respect of the following liabilities and expenses incurred for acts performed as an office holder, either in advance of an event or following an event, provided a provision authorizing such indemnification is contained in its articles of association:


•			financial liability imposed on him or her in favor of another person pursuant to a judgment, settlement or arbitrator’s award approved by a court. However, if an undertaking to indemnify an office holder with respect to such liability is provided in advance, then such an undertaking must be limited to events which, in the opinion of the board of directors, can be foreseen based on the company’s activities when the undertaking to indemnify is given, and to an amount or according to criteria determined by the board of directors as reasonable under the circumstances, and such undertaking shall detail the abovementioned events and amount or criteria;


•			reasonable litigation expenses, including attorneys’ fees, incurred by the office holder (1) as a result of an investigation or proceeding instituted against him or her by an authority authorized to conduct such investigation or proceeding, provided that (i) no indictment was filed against such office holder as a result of such investigation or proceeding; and (ii) no financial liability, such as a criminal penalty, was imposed upon him or her as a substitute for the criminal proceeding as a result of such investigation or proceeding or, if such financial liability was imposed, it was imposed with respect to an offense that does not require proof of criminal intent and (2) in connection with a monetary sanction;


•			reasonable litigation expenses, including attorneys’ fees, incurred by the office holder or imposed by a court in proceedings instituted against him or her by the company, on its behalf or by a third-party or in connection with criminal proceedings in which the office holder was acquitted or as a result of a conviction for an offense that does not require proof of criminal intent; and


•			expenses, including reasonable litigation expenses and legal fees, incurred by an office holder in relation to an administrative proceeding instituted against such office holder, or certain compensation payments made to an injured party imposed on an office holder by an administrative proceeding, pursuant to certain provisions of the Israeli Securities Law, 1968 (the “Israeli Securities Law”).

An Israeli company may insure an office holder against the following liabilities incurred for acts performed as an office holder if and to the extent provided in the company’s articles of association:


•			a breach of the duty of loyalty to the company, to the extent that the office holder acted in good faith and had a reasonable basis to believe that the act would not prejudice the company;


•			a breach of the duty of care to the company or to a third-party, including a breach arising out of the negligent conduct of the office holder;


•			a financial liability imposed on the office holder in favor of a third-party;


•			a financial liability imposed on the office holder in favor of a third-party harmed by a breach in an administrative proceeding; and


•			expenses, including reasonable litigation expenses and legal fees, incurred by the office holder as a result of an administrative proceeding instituted against him or her pursuant to certain provisions of the Israeli Securities Law.

An Israeli company may not indemnify or insure an office holder against any of the following:


•			a breach of the duty of loyalty, except to the extent that the office holder acted in good faith and had a reasonable basis to believe that the act would not prejudice the company;


•			a breach of the duty of care committed intentionally or recklessly, excluding a breach arising out of the negligent conduct of the office holder;


•			an act or omission committed with intent to derive illegal personal benefit; or


•			a fine, monetary sanction or forfeit levied against the office holder.

Under the Companies Law, exculpation, indemnification and insurance of office holders must be approved by the compensation committee and the board of directors (and, with respect to directors and the Chief Executive Officer, by shareholders). However, under regulations promulgated under the Companies Law, the insurance of office holders shall not require shareholder approval and may be approved by only the compensation committee, if the engagement terms are determined in accordance with the company’s compensation policy, that compensation policy was approved by the shareholders by the same special majority required to approve a compensation policy, provided that the insurance policy is on market terms and the insurance policy is not likely to materially impact the company’s profitability, assets or obligations.

Our amended and restated articles of association allow us to indemnify and insure our office holders for any liability imposed on them as a consequence of an act (including any omission) which was performed by virtue of being an office holder. Our office holders are currently covered by a directors and officers’ liability insurance policy.

We have entered into agreements with each of our directors and executive officers exculpating them, to the fullest extent permitted by law, from liability to us for damages caused to us as a result of a breach of duty of care and undertaking to indemnify them to the fullest extent permitted by law. This indemnification is limited to events determined as foreseeable by the board of directors based on our activities, and to an amount or according to criteria determined by the board of directors as reasonable under the circumstances. The maximum indemnification amount set forth in such agreements is limited to an amount equal to the higher of (i) $35 million and, (ii) 25% of our total shareholders’ equity as reflected in our most recent consolidated financial statements prior to the date on which the indemnity payment is made, and (iii) ten percent (10%) of the Company Total Market Cap (which shall mean the average closing price of our ordinary shares over the 30 trading days prior to the actual payment of indemnification multiplied by the total number of our issued and outstanding shares as of the date of actual payment, other than indemnification for an offering of securities to the public, including by a shareholder in a secondary offering, in

which case the maximum indemnification amount is limited to the gross proceeds raised by us and/or any selling shareholder in such public offering. The maximum amount set forth in such agreements is in addition to any amount paid (if paid) under insurance and/or by a third-party pursuant to an indemnification arrangement.

In the opinion of the Commission, indemnification of directors and office holders for liabilities arising under the Securities Act of 1933, as amended (the “Securities Act”), however, is against public policy and therefore unenforceable.
