Mr. Berggruen has informed the Issuer Board of his decision not to seek reelection to the Issuer Board, and his term will expire at the Issuer’s 2018 Annual Meeting of Stockholders that is scheduled to be held on June 25, 2018.

As a result of the Proxy

Agreement, the Mariposa Reporting Persons and Berggruen Reporting Persons have formed a “group” for purposes of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended, and Rule 13d-5(b)(1) thereunder. Franklin has no pecuniary interest in the Common Stock or Series A Preferred Stock held by BHL as a result of the Proxy Agreement.

Paragraphs (a) – (c) of Item 5 of the Statement are hereby amended and restated in their entirety as follows:

This amount consists of (i) 12,028,740 shares of Common Stock and (ii) 893,000 shares of Series A Preferred Stock of the Issuer that are convertible at any time at the option of the holder into the same number of shares of Common Stock. In the aggregate, such 12,921,740 shares of Common Stock represent approximately 4.5% of all outstanding shares of Common Stock (calculated based on 288,132,692 shares of Common Stock outstanding as April 27, 2018 (as reported in the Issuer’s definitive Proxy Statement filed on April 30, 2018) and assuming the conversion of the Berggruen Reporting Person’s shares of Series A Preferred Stock, but without including any conversion of shares of Series A Preferred Stock held by any other person).

AGREEMENT, dated as of May 3, 2018 (this “Agreement”), among Martin E. Franklin, an individual resident of the State of Florida (“Franklin”), and Berggruen Holdings Ltd., a British Virgin Islands (“BVI”) business company (“BHL”) owned by Nicolas Berggruen Charitable Trust, a BVI trust.

WHEREAS, BHL beneficially owns (i) 12,028,740 shares of common stock, par value $0.01 per share (the “Common Stock”) of Platform Specialty Products Corporation, a Delaware corporation listed on the New York Stock Exchange (“Platform”) and (ii) 893,000 shares of Series A Preferred Stock of Platform (the “Preferred Stock”) that are convertible into the same number of shares of Common Stock at any time at the option of the holder ((i) and (ii) above and any shares of Common Stock or other securities convertible or exchangeable for Common Stock acquired by BHL (or any of its direct or indirect subsidiaries) after the date of this Agreement, being referred to collectively as the “Berggruen Shares”).

WHEREAS, BHL has agreed to irrevocably grant to and appoint Franklin, and any individual(s) designated in writing by Franklin, as proxy and attorney-in-fact (with full power of substitution), for and in their name, place, and stead, to vote all of the Berggruen Shares at any meeting of the Platform stockholders or to otherwise consent to any corporate or shareholder action for so long as Franklin serves as director on the Board of Directors of Platform (the “Proxy Term”).

NOW, THEREFORE, in consideration of the foregoing and intending to be legally bound hereby, the parties hereto agree as follows:

ARTICLE I

GRANT OF PROXY

Section 1.1. Irrevocable Proxy. BHL hereby irrevocably and unconditionally, to the fullest extent permitted by law (but only during the Proxy Term), appoints Franklin as its sole and exclusive attorney-in-fact and proxy, with full power of substitution and re-substitution, to vote and exercise during the Proxy Term (but only during the Proxy Term), in a manner Franklin deems in his sole and absolute discretion appropriate, all voting, consent and similar rights (to the full extent that BHL would be entitled to so vote and exercise them, and including, without limitation, the power to execute and deliver written consents) at every annual, special or adjourned meeting of holders of any security issued by Platform and in every written consent in lieu of such a meeting, with respect to any and all Berggruen Shares on the terms and conditions set forth in this Agreement. Upon the execution of this Agreement, any and all prior proxies given by BHL with respect to the Berggruen Shares are hereby revoked and, subject to the terms and conditions set forth in this Agreement, BHL agrees not to grant during the Proxy Term any subsequent proxies with respect to the Berggruen Shares if and to the extent inconsistent with this Section 1.1.

This Proxy shall continue in full force and effect until the expiration of the Proxy Term and BHL hereby waives any and all right to cancel this Proxy at any time during the time period described herein.

BHL further acknowledges and agrees that, until the expiration of the Proxy Term, the Proxy granted in this Section 1.1 shall extend to any shares of Common Stock or other securities convertible or exchangeable for Common Stock acquired by BHL (or any of its direct or indirect subsidiaries) after the date of this Agreement.
