| In connection with the announced proposed merger (the “Merger”) of the Issuer and La Jolla Pharmaceutical Company (“La Jolla”), on June 24, 2020, the Master Fund entered into a support agreement (the “Support Agreement”) with: (i) La Jolla; and (ii) TTP Merger Sub, Inc., a wholly-owned subsidiary of La Jolla (the “La Jolla Subsidiary”). Pursuant to the Support Agreement, the Master Fund agreed to, among other things, (i) vote against other proposals to acquire the Issuer, and (ii) subject to certain exceptions, to tender its Shares in connection with the La Jolla Subsidiary’s cash tender offer, on behalf of La Jolla, to acquire all of the Issuer’s Shares. The Support Agreement also sets forth terms relating to the treatment of warrants of the Issuer currently held by the Master Fund upon consummation of the Merger. The Support Agreement will terminate upon the first to occur of: (i) the termination of the Agreement and Plan of Merger, dated June 24, 2020, by and among the Issuer, La Jolla and the La Jolla Subsidiary (the “Merger Agreement”); (ii) the effective time of the Merger; (iii) any amendment to the Merger Agreement that reduces the amount, or changes the form, of consideration payable to the Master Fund in the transactions contemplated by the Merger and related agreements, imposes additional restrictions on the Master Fund or otherwise materially and adversely impacts the Master Fund; (iv) a Company Adverse Change in Recommendation (as such term is defined in the Merger Agreement); or (v) the mutual written consent of the Master Fund and La Jolla. The foregoing was a summary of certain material terms of the Support Agreement. The foregoing description is not, and does not purport to be, complete and is qualified in its entirety by reference to the full text of the form of Support Agreement, which has been filed as Exhibit B hereto and is incorporated herein by reference. Mr. Boyd and Keith Maher, a Managing Director at Armistice Capital, currently serve as members of the Issuer’s board of directors (the “Board”). The Reporting Persons purchased the Shares for investment in the ordinary course of their investment activities based on the Reporting Persons’ belief that the Shares, when purchased, were undervalued and represented an attractive investment opportunity. The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Depending on various factors including, without limitation, the Issuer’s financial position, the price levels of the Shares, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, engaging in communications with management and/or the Board, engaging in discussions with stockholders of the Issuer and others about the Issuer and the Reporting Persons’ investment, reshaping the Issuer's corporate strategy, revitalizing the Issuer’s promising Research and Development pipeline, restructuring the Issuer’s expense base, recommending business development transactions including mergers and acquisitions, proposing changes to management, operations and the structure of the Board (including the composition of the Board), purchasing additional Shares, selling some or all of their Shares, engaging in short selling of or any hedging or similar transaction with respect to the Shares, or changing their intention with respect to any and all matters referred to in subparagraphs (a) - (j) of Item 4 of Schedule 13D. Except as otherwise set forth herein, the Reporting Persons do not have any present plans or proposals which would relate to, or result in, the matters set forth in subparagraphs (a) – (j) of Item 4 of Schedule 13D. However, subject to market conditions and in compliance with applicable securities laws, the Reporting Persons reserve the right, at a later date, to effect one or more of such changes or transactions in the number of Shares they may be deemed to beneficially own in open-market or privately negotiated transactions, on such terms and at such times as the Reporting Persons may deem advisable. |
