RECITALS

A. The Employee presently serves as Chief Financial Officer and Senior Vice President, Finance of the Company and performs significant strategic and management responsibilities necessary to the continued conduct of the Company’s business and operations.

Exhibit A

RELEASE

In exchange for the severance pay and benefits described in the Change in Control Agreement between SciClone Pharmaceuticals, Inc.

I am knowingly, willingly and voluntarily releasing any claims I may have under the ADEA. I acknowledge that the consideration given for the release in the preceding paragraph hereof is in addition to anything of value to which I was already entitled. I further acknowledge that I have been advised by this writing, as required by the ADEA, that: (a) this Release does not apply to any rights or claims that may arise after I sign it; (b) I have the right to consult with an attorney prior to signing this Release; (c) I have twenty-one (21) days to consider this Release (although I may choose to voluntarily sign this Release earlier); (d) I have seven (7) days after I sign this Release to revoke it; and (e) this Release shall not be effective until the eighth day after it is signed by me.

In giving this release, which includes claims that may be unknown to me at present, I acknowledge that I have read and understand Section 1542 of the California Civil Code which reads as follows: “A general release does not extend to claims which the creditor does not know or suspect to exist in his or her favor at the time of executing the release, which if known by him or her must have materially affected his or her settlement with the debtor.” I hereby waive and relinquish all rights and benefits under that section and any law of any jurisdiction of similar effect with respect to my release of any unknown claims I may have, and I affirm that it is my intention to release all known and unknown claims that I have or may have against the parties released above.

This Release contains the entire agreement between the Company and me regarding the subjects above, and it cannot be modified except by a document signed by me and an authorized representative of the Company.
