As previously disclosed in the Current Report on Form 8-K filed with the Securities and Exchange Commission (“SEC”) by SciClone Pharmaceuticals, Inc. (“SciClone” or the “Company”) on June 8, 2017, SciClone entered into an Agreement and Plan of Merger (the “Merger Agreement”), dated June 7, 2017, by and among the Company, Silver Biotech Investment Limited, a company organized under the laws of the Cayman Islands (“Holdco”), and Silver Delaware Investment Limited, a Delaware corporation and wholly owned subsidiary of Holdco (“Merger Sub”), under which Merger Sub shall be merged with and into the Company (the “Merger”), with the Company continuing after the Merger as the surviving corporation and subsidiary of Holdco.

On October 13, 2017, pursuant to the terms of the Merger Agreement, Holdco completed its acquisition of the Company through the merger of Merger Sub with and into the Company, with the Company continuing after the Merger as the surviving corporation and subsidiary of Holdco.

In addition, at the Effective Time, each award of restricted stock units and performance restricted stock units (whether vested or unvested) was cancelled and extinguished without payment, except as provided by the Merger Agreement with respect to any required deferred payment.

In addition, at the Effective Time, each stock option that was vested and unexercised as of immediately prior to the Effective Time was cancelled and converted into the right to receive from the Company a cash payment (without interest) equal to the product of (i) the excess, if any, of (x) the Merger Consideration over (y) the per share exercise price of such stock option and (ii) the number of shares of Common Stock subject to such stock option as of the Effective Time. Except as otherwise provided in the preceding sentence, each outstanding and unexercised stock option as of the Effective Time was cancelled and extinguished without payment.
