Re: Equity Commitment Letter

Ladies and Gentlemen:

This letter sets forth the commitment of the undersigned (the “Sponsor”), subject to (i) the terms and conditions contained in an agreement and plan of merger (the “Merger Agreement”) to be entered into by and among Silver Biotech Investment Limited, a company incorporated in the Cayman Islands with limited liability (“Holdco”), Silver Delaware Investment Limited, a Delaware corporation and wholly-owned subsidiary of Holdco (“Merger Sub”), and SciClone Pharmaceuticals, Inc., a Delaware corporation (the “Company”), pursuant to which, upon the terms and subject to the conditions set forth therein, Merger Sub will be merged with and into the Company (the “Merger”), and (ii) the terms and conditions contained herein, to subscribe for, directly or indirectly, certain newly issued ordinary shares of Holdco. Concurrently with the delivery of this letter agreement, GL China Opportunities Fund II L.P., a limited partnership organized under the laws of the Cayman Islands, GL China Opportunities Fund II (Canada) L.P., a limited partnership registered in Canada (collectively, the “GL Sponsor”), Bank of China Group Investment Limited, a company incorporated under the laws of Hong Kong, Mr. Weihang Zhu, a citizen of the People’s Republic of China, and CDH Fund V, L.P., a limited partnership organized under the laws of the Cayman Islands, (collectively with the GL Sponsor, the “Other Sponsors” and, each, an “Other Sponsor”) are entering into letter agreements substantially identical to this letter agreement (each an “Other Sponsor Equity Commitment Letter”) committing to subscribe for or cause to be subscribed for, directly or indirectly, certain newly issued ordinary shares of Holdco. Capitalized terms used but not defined herein shall have the meaning ascribed to them in the Merger Agreement.

1.         Commitment.   The Sponsor hereby commits, subject to the terms and conditions set forth herein, to subscribe, or cause to be subscribed, directly or indirectly through Ascendent Silver (Cayman) Limited(the “SPV”) or one or more Affiliates (which shall include, for the purpose of this letter, any other investment entity managed or advised by the Sponsor or its Affiliates) as provided in the last sentence of this Section 1, for newly issued ordinary shares of Holdco and to pay to Holdco in immediately available funds at or prior to the Effective Time an aggregate cash purchase price equal to $60 million (such sum, subject to adjustment as set forth in this Section 1, the “Commitment”), and shall cause Holdco, upon receipt of the Commitment, to use such amount only to (i) fund a portion of the Merger Fund and any other amounts required to be paid by Holdco pursuant to the Merger Agreement to consummate the transactions contemplated thereby and (ii) pay related fees and expenses pursuant to the Merger Agreement (collectively, the “Total Funding Requirement”). Notwithstanding anything to the contrary contained herein, the Sponsor shall not, under any circumstances, be obligated to contribute more than the Commitment to Holdco and the liability of the Sponsor hereunder shall in no event exceed the amount of the Commitment. In the event the amount of the Commitment, together with the total amount of commitments made by the Other Sponsors under the Other Sponsor Equity Commitment Letters (collectively, the “Other Commitments” and, together with the Commitment”, the “Total Commitment”) and the other financing arrangements contemplated by the Merger Agreement, exceeds the Total Funding Requirement, the amount to be funded under this letter shall, unless otherwise agreed in writing by the Sponsor, be reduced by Holdco on a pro rata basis based on the Commitment and the Total Commitment, to the level sufficient to, in combination with the other financing arrangements contemplated by the Merger Agreement, fully fund the Total Funding Requirement. The Sponsor may allocate all or a portion of the Commitment to the SPV or one or more of its Affiliates; provided, that (a) such allocation shall not relieve the Sponsor of its obligations hereunder if the SPV or such Affiliate to which the Commitment is allocated does not perform its obligations with respect to the allocated Commitment, and (b) the Commitment hereunder will only be reduced by any amounts actually contributed to Holdco by the SPV or such Affiliate to which the Commitment is allocated (and not returned) at or prior to the Closing Date for the purpose of funding a portion of the Total Funding Requirement.

2.         Conditions to Funding. The payment of the Commitment to Holdco shall be subject to (a) the satisfaction, or waiver, by Holdco of each of the conditions to Holdco’s and Merger Sub’s obligations to effect the Merger set forth in Section 9.1 and Section 9.3 of the Merger Agreement (other than those conditions that by their nature are to be satisfied at the Closing but subject to the prior or substantially concurrent satisfaction of such conditions), (b) the substantially concurrent occurrence of the Closing, (c) the Debt Financing and/or the Alternative Debt Financing (if applicable) having been funded or will be funded at the Closing in accordance with the terms of the Debt Commitment Letter or the Alternative Debt Financing Documents (if applicable) if the Commitment and the Other Commitments are funded at the Closing, and (d) the substantially contemporaneous closing of the contributions contemplated by the Other Sponsor Equity Commitment Letters, which shall not be modified, amended or altered in any manner adverse to the Sponsor without the Sponsor’s prior written consent, provided, however, that the satisfaction or failure of the condition set forth in clause (d) shall not limit or impair the ability of Holdco or the Company to seek enforcement of the obligations of the Sponsor under and in accordance with this letter if and only if (x) Holdco or the Company, as applicable, is also seeking enforcement of the Other Sponsor Equity Commitment Letters or (y) each Other Sponsor has satisfied or is prepared to satisfy its obligations under its Other Sponsor Equity Commitment Letter.

3.         Termination.  The obligation of the Sponsor to fund its Commitment will terminate automatically and immediately to the extent described below upon the earlier to occur of (i) the Effective Time; provided that the Sponsor shall at or prior to the Effective Time have fully funded and paid or procure the funding and payment to Holdco the Commitment and fully performed other obligations hereunder, and (ii) the valid termination of the Merger Agreement in accordance with its terms. Upon termination of this letter, the Sponsor shall not have any further obligations or liabilities hereunder.
