104H Tax Rulings

On February 14, 2019, Orbotech Ltd. (the “Company” or “Orbotech”) announced that the Israel Tax Authority (the “ITA”) has issued tax rulings with respect to the tax treatment applicable to the Stock Merger Consideration payable to (i) Orbotech’s Israeli-resident shareholders (the “Public Shareholders Tax Ruling”), and (ii) Orbotech’s Israeli-resident interested parties (as such term is defined therein, generally, the Company’s board members, Chief Executive Officer and shareholders holding approximately 5% or more of the Company’s outstanding shares) (the “Interested Parties” and such ruling, the “Interested Parties Tax Ruling”). The Public Shareholders Tax Ruling and the Interested Parties Tax Ruling shall collectively be referred to herein as the “104H Tax Rulings”.

The 104H Tax Rulings were issued in connection with the pending merger transaction involving the Company, KLA-Tencor Corporation (“KLA-Tencor”) and Tiburon Merger Sub Technologies Ltd. (such merger, the “Merger”). Capitalized terms used but not defined herein shall have the meanings ascribed to such terms in the Agreement and Plan of Merger dated as of March 18, 2018, as amended (the “Merger Agreement”), filed with the Securities and Exchange Commission as part of Exhibit 99.1 of the Company’s Form 6-K on June 7, 2018.

As previously announced, the ITA previously issued two additional tax rulings in connection with the Merger with respect to: (i) withholding of Israeli tax applicable to the Merger Consideration payable to the Company’s shareholders and foreign-resident employees, filed with the Securities and Exchange Commission as part of Exhibit 99.1 of the Company’s Form 6-K on January 31, 2019 (the “Withholding Tax Ruling”); and (ii) the tax treatment applicable to holders of Orbotech options, RSUs and shares issued to certain directors and employees of Orbotech under Section 102 of the Ordinance and to certain directors of Orbotech and others under Section 3(i) of the Ordinance, filed with the Securities and Exchange Commission as Exhibit 99.1 of the Company’s Form 6-K on October 10, 2018 (the “102 Tax Ruling”).

The following is a summary discussion of the material Israeli income tax considerations in connection with the Merger, applicable to Orbotech’s Israeli-resident shareholders. The following summary is included for general information purposes only, is based upon current Israeli tax law and the 104H Tax Rulings and should not be construed as or considered to be tax advice to any particular holder of Orbotech shares. No assurance can be given that future legislation, regulations or interpretations will not significantly change the tax considerations described below, and any such change may apply retroactively. This summary is not intended to be and does not constitute a complete review of all material terms of the 104H Tax Rulings, nor does it discuss all material aspects of Israeli tax consequences that may apply to particular holders of Orbotech shares (in light of their particular circumstances). YOU SHOULD CAREFULLY READ THE TRANSLATIONS OF THE 104H TAX RULINGS ATTACHED HERETO AND CONSULT YOUR TAX

ADVISORS REGARDING THE TAX CONSEQUENCES OF THE MERGER TO YOU. In the event of any discrepancy between the translations of the 104H Tax Rulings and the official, original Hebrew versions of the 104H Tax Rulings, the official, original Hebrew versions of the 104H Tax Rulings shall govern. In addition, the 104H Tax Rulings should be read in conjunction with the Withholding Tax Ruling and 102 Tax Ruling in order to fully understand the tax consequences applicable to the Merger Consideration payable to you.

Stock Merger Consideration payable to Israeli-Resident Public Shareholders (other than Interested Parties).

With respect to the Stock Merger Consideration payable to Israeli-resident shareholders other than Interested Parties (collectively, the “Public Shareholders”), the provisions of Section 104H of the Ordinance shall apply such that the sale of Orbotech shares in exchange for shares of KLA-Tencor common stock shall not be deemed, on the Effective Date, as a sale under the Ordinance, and the ‘sale event’ shall be deferred until such time as such shares of KLA-Tencor common stock are actually sold by the shareholder. With respect to Public Shareholders whose shares are registered directly with American Stock Transfer & Trust Company LLC, such deferral of the tax event is subject to the deposit of the shares of KLA-Tencor common stock with a trustee (to be designated by KLA-Tencor for such purpose) until the date such shares of KLA-Tencor common stock are actually sold by such Shareholder.

The 104H Tax Rulings provide that any shareholder of the Company may request to treat the sale of its Orbotech shares in exchange for shares of KLA-Tencor common stock as a tax event. If a shareholder makes such a request, the provisions of the 104H Tax Rulings shall not apply with respect thereto and the taxation of such shareholder shall be in accordance with the law and the Withholding Tax Ruling.

The 104H Tax Rulings also provide that the shares of KLA-Tencor common stock issued to holders of Company 102 Shares, Company 102 Compensatory Awards and other Company Shares or other Company Compensatory Awards otherwise held by the 102 Trustee (including on behalf of the Interested Parties) shall be deposited either with the 102 Trustee or the KLA-Tencor 102 trustee who shall be responsible for tax withholding with respect thereto.

Stock Merger Consideration payable to Israeli Interested Parties.

With respect to the Stock Merger Consideration payable to Israeli-resident Interested Parties (other than with respect to Company 102 Shares, Company 102 Compensatory Awards and other Company Shares or other Company Compensatory Awards held by the 102 Trustee, as aforesaid), the provisions of Section 104H of the Ordinance shall apply such that the sale of Orbotech shares in exchange for shares of KLA-Tencor common stock shall not be deemed, on the Effective Date, as a sale under the Ordinance, and the ‘sale event’ shall be deferred until the earlier of the date on which such shares of KLA-Tencor common stock are actually sold by such Interested Party or the end of the ‘Deferral Period’. The Deferral Period shall end, with respect to half of the newly issued shares of KLA-Tencor common stock, upon the lapse of 24 months following the exchange of the Orbotech shares for such shares of KLA-Tencor common stock and, with respect to the other half of such newly issued shares of KLA-Tencor common stock, upon the lapse of 48 months following the exchange of the Orbotech shares for such shares of KLA-Tencor common stock. Such deferral of the tax event is subject to the deposit of the shares of KLA-Tencor common stock with a trustee (to be designated by KLA-Tencor for such purpose). Each Israeli-resident Interested Party who wishes to become eligible for the tax deferral afforded under the 104H Tax Rulings should notify the ITA of its election within 30 days of the issuance of the 104H Tax Rulings.
