                         SCICLONE PHARMACEUTICALS, INC.
                           CHANGE IN CONTROL AGREEMENT

        This Change in Control Agreement (the "Agreement") is effective as of
November 19, 1999, by and between Alfred Rudolph, MD (the "Employee") and
SciClone Pharmaceuticals, Inc., a California corporation (the "Company").

                                    RECITALS

        A. The Employee presently serves as Chief Operating Officer of the
Company and performs significant strategic and management responsibilities
necessary to the continued conduct of the Company's business and operations.

        B. The Board of Directors of the Company (the "Board") has determined
that it is in the best interests of the Company and its shareholders to assure
that the Company will have the continued dedication and objectivity of the
Employee, notwithstanding the possibility or occurrence of a Change in Control
(as defined below) of the Company.

        C. The Board believes that it is imperative to provide the Employee with
certain severance benefits upon the Employee's termination of employment
following a Change in Control that will provide the Employee with enhanced
financial security and provide sufficient incentive and encouragement to the
Employee to remain with the Company following a Change in Control.

                                    AGREEMENT

        The Employee and the Company agree as set forth below:

        1. Terms of Employment. The Company and the Employee agree that the
Employee's employment is "at will" and that their employment relationship may be
terminated by either party at any time, with or without cause, and, if
applicable, in accordance with Section 2 below. If the Employee's employment
with the Company terminates for any reason following a Change in Control, but on
or before the first anniversary of the Change in Control, the Employee shall not
be entitled to any payments, benefits, damages, awards or compensation other
than as provided by this Agreement. During his or her employment with the
Company, the Employee agrees to devote his or her full business time, energy and
skill to his or her duties with the Company. These duties shall include, but not
be limited to, any duties consistent with the Employee's position that may be
assigned to the Employee from time to time by the Company or the Board.

        2. Severance Benefits Upon Termination following a Change in Control.
Subject to the limitations set forth in Sections 3 and 4 below, if the
Employee's employment with the Company terminates following a Change in Control
but on or before the first anniversary of such Change in Control, then the
Employee shall be entitled to receive, in addition to the compensation and
benefits earned by the Employee through the date of his or her termination,
severance benefits as follows:

<PAGE>   2

               (a) Involuntary Termination. If the Employee's employment with
the Company is terminated as a result of Involuntary Termination, then the
Employee shall be entitled to receive the following severance benefits:

                      (i) The Employee shall be entitled to receive severance
pay in an amount equal to one hundred percent (100%) of his annual base salary
as in effect at the time of such termination. Any severance to which the
Employee is entitled pursuant to this section shall be paid in a lump sum, less
applicable withholding, within thirty (30) days following the Employee's
termination.

                      (ii) With respect to any unvested options to purchase
shares of the stock of the Company held by the Employee, the Employee shall
immediately become vested in full in such options at the time of such
termination.

                      (iii) The Company shall, if permitted under the Company's
existing health insurance plans, continue the Employee's existing group health
insurance coverage. If not so permitted, the Company shall reimburse the
Employee for any COBRA premiums paid by the Employee for continued group health
insurance coverage. Such health insurance coverage or reimbursement of COBRA
premiums shall continue until the earlier of (1) twelve (12) months after the
date of the Employee's Involuntary Termination or (2) the date on which the
Employee commences New Employment.

               (b) Voluntary Resignation; Termination For Cause. If the
Employee's employment terminates by reason of the Employee's voluntary
resignation (but not as a result of an Involuntary Termination) or as a result
of the Employee's termination for Cause, then the Employee shall not be entitled
to receive any severance pay or benefits under this Agreement.

               (c) Disability; Death. If the Company terminates the Employee's
employment as a result of the Employee's Disability, or death, then the Employee
shall not be entitled to receive any severance pay or benefits under this
Agreement.

        3. Release of Claims; Resignation. The Employee's entitlement to any
severance pay or benefits under Section 2(a) is conditioned upon the Employee's
execution and delivery to the Company of (a) a general release of known and
unknown claims in the form attached hereto as Exhibit A and (b) a resignation
from all of the Employee's positions with the Company, including from the Board
of Directors and any committees thereof on which the Employee serves, in a form
satisfactory to the Company.

        4. Parachute Payments. In the event that any payment or benefit received
or to be received by the Employee pursuant to this Agreement or otherwise
(collectively, the "Payments") would result in a "parachute payment" as
described in section 280G of the Internal Revenue Code of 1986, as amended,
notwithstanding the other provisions of this Agreement, the amount of such
Payments will not exceed the amount which produces the greatest after-tax
benefit to the Employee. For purposes of the foregoing, the greatest after-tax
benefit will be determined within thirty (30) days of the occurrence of such
payment to the Employee, in the Employee's sole and absolute discretion. If no
such determination is made by the Employee

                                       2

<PAGE>   3

within thirty (30) days of the occurrence of such payment, the Company will
promptly make such determination in a fair and equitable manner.

        5. Consulting Services. During the twenty-four (24) months following any
Involuntary Termination for which the Employee receives the severance pay and
benefits described in Section 2(a), the Employee shall be retained by the
Company as an independent contractor to provide consulting services to the
Company at its request for up to eight (8) hours per week. These services shall
include any reasonable requests for information or assistance by the Company,
including, but not limited to, the transition of the Employee's duties. Such
services shall be provided at mutually convenient times. For the actual
provision of such services, the Company shall pay to the Employee a consulting
fee of $1,000 per day, plus reasonable out-of-pocket expenses (for example,
travel and lodging).

        6. Definition of Terms. The following terms referred to in this
Agreement shall have the following meanings:

        In exchange for the severance pay and benefits described in the Change

                          CHANGE IN CONTROL AGREEMENT

        This Change in Control Agreement (the "Agreement") is effective as of
November 19, 1999, by and between Donald R. Sellers (the "Employee") and
SciClone Pharmaceuticals, Inc., a California corporation (the "Company").

                                    RECITALS

        A. The Employee presently serves as Chief Executive Officer and
President of the Company and performs significant strategic and management
responsibilities necessary to the continued conduct of the Company's business
and operations.

        B. The Board of Directors of the Company (the "Board") has determined
that it is in the best interests of the Company and its shareholders to assure
that the Company will have the continued dedication and objectivity of the
Employee, notwithstanding the possibility or occurrence of a Change in Control
(as defined below) of the Company.

        C. The Board believes that it is imperative to provide the Employee with
certain severance benefits upon the Employee's termination of employment
following a Change in Control that will provide the Employee with enhanced
financial security and provide sufficient incentive and encouragement to the
Employee to remain with the Company following a Change in Control.

                                    AGREEMENT

        The Employee and the Company agree as set forth below:

        1. Terms of Employment. If the Employee's employment with the Company
terminates for any reason following a Change in Control, but on or before the
first anniversary of the Change in Control, the Employee shall not be entitled
to any payments, benefits, damages, awards or compensation other than as
provided by this Agreement. During his or her employment with the Company, the
Employee agrees to devote his or her full business time, energy and skill to his
or her duties with the Company. These duties shall include, but not be limited
to, any duties consistent with the Employee's position that may be assigned to
the Employee from time to time by the Company or the Board.

        2. Severance Benefits Upon Termination following a Change in Control.
Subject to the limitations set forth in Sections 3 and 4 below, if the
Employee's employment with the Company terminates following a Change in Control
but on or before the first anniversary of such Change in Control, then the
Employee shall be entitled to receive, in addition to the compensation and
benefits earned by the Employee through the date of his or her termination,
severance benefits as follows:

<PAGE>   2
               (a) Involuntary Termination. If the Employee's employment with
the Company is terminated as a result of Involuntary Termination, then the
Employee shall be entitled to receive the following severance benefits:

                      (i) The Employee shall be entitled to receive severance
pay in an amount equal to one hundred percent (100%) of his annual base salary
as in effect at the time of such termination. Any severance to which the
Employee is entitled pursuant to this section shall be paid in a lump sum, less
applicable withholding, within thirty (30) days following the Employee's
termination.

                      (ii) With respect to any unvested options to purchase
shares of the stock of the Company held by the Employee, the Employee shall
immediately become vested in full in such options at the time of such
termination.

                      (iii) The Company shall, if permitted under the Company's
existing health insurance plans, continue the Employee's existing group health
insurance coverage. If not so permitted, the Company shall reimburse the
Employee for any COBRA premiums paid by the Employee for continued group health
insurance coverage. Such health insurance coverage or reimbursement of COBRA
premiums shall continue until the earlier of (1) twelve (12) months after the
date of the Employee's Involuntary Termination or (2) the date on which the
Employee commences New Employment.

               (b) Voluntary Resignation; Termination For Cause. If the
Employee's employment terminates by reason of the Employee's voluntary
resignation (but not as a result of an Involuntary Termination) or as a result
of the Employee's termination for Cause, then the Employee shall not be entitled
to receive any severance pay or benefits under this Agreement.

               (c) Disability; Death. If the Company terminates the Employee's
employment as a result of the Employee's Disability, or death, then the Employee
shall not be entitled to receive any severance pay or benefits under this
Agreement.

        3. Release of Claims; Resignation. The Employee's entitlement to any
severance pay or benefits under Section 2(a) is conditioned upon the Employee's
execution and delivery to the Company of (a) a general release of known and
unknown claims in the form attached hereto as Exhibit A and (b) a resignation
from all of the Employee's positions with the Company, including from the Board
of Directors and any committees thereof on which the Employee serves, in a form
satisfactory to the Company.

        4. Parachute Payments. In the event that any payment or benefit received

        In exchange for the severance pay and benefits described in the Change

subsidiaries, and their officers, directors, employees, attorneys, shareholders,

and causes of action of every kind and nature, whether known or unknown, based
upon or arising out of any agreements, events, acts, omissions or conduct at any
time prior to and including the execution date of this Release, including, but
not limited to: all claims concerning my employment with the Company or the
termination of that employment; all claims pursuant to any federal, state or
local law, statute, or cause of action, including, but not limited to, the
federal Civil Rights Act of 1964, as amended; the federal Americans with
Disabilities Act of 1990; the federal Age Discrimination in Employment Act of
1967, as amended ("ADEA"); the California Fair Employment and Housing Act, as
amended; tort law; contract law; wrongful discharge; race, sex, age or other

of the implied covenant of good faith and fair dealing.

        I am knowingly, willingly and voluntarily releasing any claims I may

in the preceding paragraph hereof is in addition to anything of value to which I

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
