It is already emphasized that the merger does not constitute a merger as defined in Section 103 of the Ordinance which is entitled, upon the fulfilment of the conditions stipulated in Part E2 of the Ordinance, to the benefits and conditions which are determined in the second chapter of Part E2 of the Ordinance, and therefore, the use of the term merger in this context refers to a transaction in which KLA has in fact purchased, directly or indirectly, all of the shares of Orbotech, i.e. a share purchase transaction.

A summary chart of the relevant holding structure specifying the Transaction is attached as Annex A. The closing of the Merger is expected to be carried-out subject to the fulfillment of various preliminary conditions which are anticipated to be satisfied during the first quarter of 2019 (the “Closing Date”).

3.13.

It is clarified that the calculation method of the original price of the Entitling Shares, with respect to Section 104H(b)(1A)(b) of the Ordinance, shall be as follows:

The exchange as per Section 1.12 shall be deemed as a sale of part of the Entitling Shares which are being exchanged in consideration for cash which was received by the Entitled Shareholders under an agreement.

In this respect, “part of the exchanged Entitling Shares” shall be determined according to the ratio between the Cash Consideration and the Cash Consideration together with the Stock Consideration that were received within the Merger (the Transaction Consideration), multiplied by the number of securities of the Entitling Shares held by the Entitled Shareholder (the “Sold Entitling Shares”).

The calculation formula regarding considerations received by an Entitled Shareholder:

A – Cash Consideration

B – Stock Consideration—the value of 0.25 of a share of KLA common stock which was received according to the average of 30 trading days preceding the Closing Date

C – the number of the Company’s securities held by an Entitled Shareholder

LOGO

For the capital gains calculated in the sale of the Sold Entitling Shares, tax shall be withheld from the consideration on the exchange date, pursuant to the Tax Withholding Regulations. It is noted that in calculating the gains due to the Cash Consideration, the original price to be attributed to the Cash Consideration shall be the original price of the Sold Entitling Shares while first attributing the cost of the first layers of the Sold Entitling Shares, in the FIFO method. The total cost of the Entitling Shares net of the cost which was attributed to the Sold Entitling Shares shall be attributed to the KLA shares which were received as per Section 1.12.2, of the Interested Public Tax Ruling and the Interested Parties Tax Ruling as defined in Section 1.18.
