         The following  material  contains  certain  forward-looking  statements
including statements regarding the application of ZADAXIN(R) thymosin alpha 1 in
disease  areas beyond  hepatitis B, the potential  for  regulatory  approvals of
ZADAXIN and the  launching of ZADAXIN in additional  markets,  and the Company's
expectations  regarding  increases  in revenues  from  ZADAXIN and  increases in
marketing and research and  development  expense  levels.  These  statements are
subject  to  certain  risks and  uncertainties.  These  risks and  uncertainties
include the Company's  current  reliance on a single product,  ZADAXIN  thymosin
alpha 1, for its  revenues,  the absence of  regulatory  approval for ZADAXIN in
significant  markets,  the expensive,  time  consuming and uncertain  regulatory
approval  process,  risks associated with the manufacture and supply of ZADAXIN,
and competition from competing therapies, uncertainties regarding the outcome of
the Company's  efforts to commercialize  additional  products,  as well as other
risks and  uncertainties  described  herein and in the  Company's  other reports
filed with the Securities and Exchange Commission.

                                     PART I

Item 1.    Business

         SciClone  Pharmaceuticals,  Inc.  ("SciClone"  or the  "Company") is an
international biopharmaceutical company involved in the acquisition, development
and  commercialization  of  pharmaceuticals  worldwide.  The Company  focuses on
specialist  oriented  products  for  chronic  and   life-threatening   diseases,
including  hepatitis  B and  C,  cancer,  immune  system  disorders  and  cystic
fibrosis.  The Company's strategy is to acquire readily  commercializable  drugs
and to focus  its  resources  on their  commercialization.  The  Company's  lead
product is ZADAXIN  thymosin alpha 1, a synthetic  immunomodulator.  The Company
has received  approval to market and has recently  begun  marketing  ZADAXIN for
chronic  hepatitis B in China, the Philippines and Singapore.  In addition,  the
Company has filed for approval to market  ZADAXIN for this  indication in eleven
countries,  primarily in Asia, the Middle East, and Latin America.  Based on the
clinical  trials  conducted to date, the Company  believes that ZADAXIN,  either
alone or in combination with other therapies, may also have application in other
disease  areas,  including  hepatitis C, cancer and acquired  immune  deficiency
syndrome ("AIDS").

         SciClone's other product, CPX, is a synthetic compound developed by the
United States National Institutes of Health ("NIH") as a potential treatment for
cystic  fibrosis  ("CF").  CF is caused by a  mutation  in the  cystic  fibrosis
transmembrane  conductance  regulation  ("CFTR") gene. In vitro studies from the
NIH have shown that CPX binds to CFTR and permits  the CFTR to properly  perform
its chloride secretion  function.  The Company has recently received approval to
begin clinical trials of CPX in the United States.

         Internationally,   SciClone   has   partnered   with   numerous   local
pharmaceutical  distributors  to register and market its  products.  The Company
out-licenses  its products where a  collaboration  will  materially  enhance the
prospects  for  commercial  success.  For  example,  SciClone  has  licensed  to
Schering-Plough  K.K.  exclusive  rights to develop and market ZADAXIN in Japan.
The Company is currently seeking a corporate partnership arrangement for ZADAXIN
in Europe.

         The Company was incorporated in California in May 1990.

Strategy

         SciClone's  primary  business  objective is to strengthen its virtually
integrated international  biopharmaceutical  business. The Company's strategy to
achieve this objective is as follows:

                                      -3-
<PAGE>

         o     Aggressively Commercialize ZADAXIN Worldwide

         The Company's principal development and  commercialization  efforts are
currently  focused  on  ZADAXIN.  The  Company  is  aggressively   pursuing  the
commercialization  of ZADAXIN  worldwide.  The Company has filed for approval to
market  ZADAXIN for hepatitis B in  international  markets and has  distribution
agreements in place in more than  twenty-five  markets and is prepared to launch
commercialization  programs if regulatory  approvals are secured.  In all of its
current and proposed future  markets,  the Company seeks to optimize the balance
of time (and cost) to market and long-term benefit to the Company.

         o     In-License and Develop Readily Commercializable Proprietary Drugs

         The  Company  does not  engage  in drug  discovery  programs.  Instead,
SciClone seeks to in-license pharmaceutical compounds and to focus its resources
on the  development  and  commercialization  of such  compounds.  The  Company's
principal  in-licensing targets are specialist oriented,  highly differentiated,
intellectual   property-protected,   readily   commercializable   pharmaceutical
products,  particularly  products which may be eligible for accelerated approval
as potential therapies for  life-threatening or severely  debilitating  diseases
with limited or no therapeutic  alternatives.  In targeting  such products,  the
Company seeks to reduce the risk,  time and cost  traditionally  associated with
the commercialization of pharmaceuticals.

         o     Capitalize on Global Sales and Marketing Capabilities

         The Company has sales and marketing capabilities in targeted markets in
the Asia-Pacific region, the Middle East and Latin America. The Company has also
established foreign advisory boards and professional relationships to facilitate
sales in such  markets.  The  Company  has  expanded  its  sales  and  marketing
capabilities  in such markets by entering  into  arrangements  with  established
local  companies  capable  of  keeping  pace with  changing  local  customs  and
regulatory requirements.

ZADAXIN(R) Thymosin Alpha 1

         ZADAXIN thymosin alpha 1 is a naturally occurring 28 amino acid peptide
that is produced for therapeutic use through chemical synthesis.  Thymosin alpha
1  appears  to have  significant  immunostimulatory  properties,  having  raised
lymphocyte  (white  blood  cell)  counts  and  enhanced  immune  responses  in a
substantial number of patients. Neither the drug's exact mechanism of action nor
the  receptor  for its  stimulatory  properties  has been  identified.  The drug
appears to act on immune cells that have been  stimulated  by infection or other
agents and does not appear to produce  the side  effects  associated  with other
immunostimulatory molecules, which can include fever, headache, chills, fatigue,
nausea and  inflammation.  To date,  over 1,500 patients have received  thymosin
alpha 1 with few or no significant drug-related side effects. Based on more than
seventy (70)  clinical  trials  conducted  to date,  the Company  believes  that
thymosin alpha 1, either alone or in combination with other therapies,  may have
application  across a broad spectrum of diseases,  including  hepatitis B and C,
cancer, AIDS and other immune system diseases.

         Under an  agreement  the  Company  entered  into in 1994  with  Alpha 1
Biomedicals,  Inc. ("Alpha 1"), the Company obtained marketing,  development and
manufacturing  rights  to  thymosin  alpha 1 that  are now  worldwide,  with the
exception of Italy, Spain and Portugal. Under the Alpha 1 agreement, the Company
also acquired  control over Alpha 1's patent portfolio for the drug. The Company
is using the trade name ZADAXIN for thymosin alpha 1.

                                      -4-
<PAGE>

         The Company has  received  approval  to market and has  recently  begun
marketing  ZADAXIN  for the  treatment  of  chronic  hepatitis  B in China,  the
Philippines  and Singapore and has filed for approval to market ZADAXIN for this
indication  in eleven other  countries,  primarily in Asia,  the Middle East and
Latin America and intends to make filings in additional countries.

         Sales of ZADAXIN are not  significant at this time. No assurance can be
given that  ZADAXIN  approvals  will be obtained in  additional  countries  in a
timely  fashion  or at all.  The  Company's  launch of  ZADAXIN  in  China,  the
Philippines and Singapore is the first commercial introduction of ZADAXIN by the
Company,  and no assurance can be given that  commercialization  of ZADAXIN will
prove  successful.  Future  sales of the  product  will be  dependent  on market
acceptance and successful distribution.  Because the Company currently relies on
ZADAXIN as its sole source of revenue,  the  failure to  demonstrate  the drug's
efficacy in future clinical trials, to obtain additional  marketing approvals or
to successfully  commercialize  the drug would have a material adverse effect on
the Company.

         Hepatitis B

         Hepatitis  B is the  second  most  common  chronic  infectious  disease
worldwide.  It is transmitted through blood transfusions,  contaminated needles,
sexual  contact  and  perinatally.  In  addition,  a large  number of people are
infected  by  unknown  means.  The  World  Health  Organization  estimates  that
approximately 350 million individuals  worldwide or 5% of the world's population
are carriers of the virus.  Among  carriers of the hepatitis B virus,  many have
asymptomatic or minimal disease, with no clinically evident symptoms.  According
to a study  published in Hepatology,  a significant  percentage of carriers have
chronic  persistent  hepatitis,  with or without clinically evident symptoms and
with evidence of mild liver  inflammation,  or chronic  active  hepatitis,  with
evidence  of liver  damage.  Carriers  of the  hepatitis B virus have a 200-fold
increased chance of developing primary liver cancer, the single largest cause of
cancer mortality  globally,  and a significant  number develop  cirrhosis of the
liver.

         The primary existing therapy for hepatitis B is alpha interferon. Alpha
interferon  is a protein that is produced  commercially  using  recombinant  DNA
techniques.  Alpha  interferon  is approved for  treatment of hepatitis B in the
United  States and Europe,  as well as in Hong Kong,  Taiwan,  China,  Japan and
other countries.

         Set forth below is more  detailed  information  regarding the status of
development of ZADAXIN as a therapy for hepatitis B in specified countries.

         China.  The  Company  launched  ZADAXIN in China in January  1997 after
receiving a license to market ZADAXIN in China as a monotherapy  (and for use in
combination with alpha interferon) for the treatment of chronic hepatitis B from
the People's  Republic of China  Ministry of Public  Health  (MOPH) in September
1996.  This  product  launch  marked  the first  introduction  of ZADAXIN by the
Company  anywhere  in the world.  The MOPH  approval  was based on a  regulatory
package  assembled from U.S. and European data in addition to a locally required
randomized and controlled clinical trial to evaluate the efficacy of ZADAXIN for
patients  suffering from hepatitis B. Patient response rates were  prospectively
defined in the study  protocol  as those  patients  whose  hepatitis B virus DNA
("HBV DNA") and hepatitis B e-antigen  ("HBeAg") levels were undetectable  after
six months of  treatment.  HBV DNA is a measure of  hepatitis B viral load while
HBeAg,  a  protein  synthesized  by the  hepatitis  B virus,  is a sign of viral
replication.  The study report  submitted to the MOPH identified a statistically
significant  response rate among patients  treated with the combination  thereby
compared with patients  treated with alpha  interferon or ZADAXIN  alone.  There
were no significant  drug-related side effects or toxicity reported with ZADAXIN
in connection with this trial.

                                      -5-

<PAGE>

         The MOPH estimates that there are more than 120 million carriers of the
hepatitis B virus in China of whom 12 million are currently active carriers.

         Philippines.  The  Company  launched  ZADAXIN in the  Philippines  as a
monotherapy  for the  treatment  of chronic  hepatitis  B in January  1997 after
receiving  approval by the  Philippines  Department of Health Bureau of Food and
Drug (BFAD).  BFAD's approval was based on clinical data from studies  conducted
in the U.S. and Europe indicating  ZADAXIN to be safe and effective for patients
suffering from chronic  hepatitis B. BFAD estimates that there are more than 6.5
million  carriers  of the  hepatitis  B  virus  in the  Philippines,  of whom an
estimated 10 to 15 percent are chronic carriers.

         Singapore. The Company received approval to market ZADAXIN in Singapore
for commercial sale for treatment of chronic  hepatitis B in September 1993. The
Company's approval requires a patient  surveillance  program which will continue
for such period as the Ministry of Health deems  necessary.  Sales of ZADAXIN in
Singapore are not significant at this time.

         Japan.  A phase I single and multiple dose ranging and  pharmacokinetic
trial and an open-label,  dose ranging phase II trial involving approximately 60
patients  have been  completed  by Schering  Plough K.K.  ("SPKK") in Japan.  In
October 1996, the Company expanded and amended its license  agreement with SPKK.
The Company agreed to transfer exclusive Japanese rights for thymosin alpha 1 to
SPKK and SPKK  agreed  to pay the  Company  certain  fees  upon  achievement  of
milestones and committed to invest additional funds to develop and commercialize
ZADAXIN in Japan.  SPKK will continue the  development  of thymosin alpha 1 as a
monotherapy  for  hepatitis  B, and study the compound in  combination  with its
Intron(R) A  (interferon  alpha 2b) for the  treatment of hepatitis C.  Clinical
studies for these two  indications  are  planned to  commence  during the second
quarter of 1997 and certain  costs will be shared by the  Company  and SPKK.  If
ZADAXIN is approved in Japan,  SPKK has  committed to purchase the drug from the
Company  at a  price  based  on  SPKK's  sales  price.  SPKK  has a  substantial
commitment to alpha interferon, which is an approved therapy for hepatitis B and
C in Japan.

         There can be no assurance  that SPKK will continue its clinical  trials
or that it will seek to  commercialize  ZADAXIN in Japan.  In any event,  a full
complement of Japanese  clinical data will be required  before any approvals for
ZADAXIN may be sought in Japan.  Even if SPKK  completes its  clinincal  trials,
there can be no assurance that clinical  results will be favorable or sufficient
to obtain product approval in Japan.

         There are estimated to be 2.6 million carriers of hepatitis B in Japan.

         United States. Alpha 1 sponsored a randomized,  double-blinded trial of
thymosin  alpha 1 for chronic active and chronic  persistent  hepatitis B in the
United States. The trial was conducted at three centers and produced data for 99
patients.  A formal  analysis  of the full  data  from  the  trial  has now been
completed  and was  presented in May 1995 at the spring  meeting of the American
Gastroenterology  Association.  The data  showed a  long-term  HBV DNA and HBeAg
negative status in 25% of patients with chronic hepatitis B compared with such a
response in 13% of those who received placebo.

         Taiwan. The Company will file for regulatory approval to market ZADAXIN
in Taiwan  after  receiving  results  from a  multicenter  open-label  phase III
chronic hepatitis B trial of ZADAXIN it sponsored in Taiwan. The audited results
of this trial showed 37 percent of patients responded to ZADAXIN, compared to 25
percent for patients taking a placebo.  Although the results of the Taiwan trial
did not achieve  statistical  significance,  the Company believes this trial has
produced the best results of any randomized and controlled  Hepatitis B trial in
Taiwan.  The Company knows of no randomized  and  

                                      -6-
<PAGE>

controlled hepatis B clinical trial conducted in Taiwan using medically accepted
end  points  of HBV DNA and HBeAg  negativity  that has  produced  statistically
significant  results  including  clinical  trials of the  approved  hepatitis  B
therapy in Taiwan,  alpha  interferon.  In a meta  analysis -- the combining and
analyzing  of  related  data -- of two U. S.  trials  and the  Taiwanese  trial,
ZADAXIN's  overall  response rate was 36 percent  compared to 19 percent for the
placebo,  a satistically  significant result (p = 0.04). The results also showed
no indications of drug toxicity and no drug-related  adverse  experiences in the
trials.

         Over 3 million Taiwanese, or 17% of the population, are carriers of the
hepatitis  B  virus.  Due to the  seriousness  of the  health  threat  posed  by
hepatitis B, Taiwan's  Department  of Health has for over a decade  conducted an
intensive program designed to control and prevent the disease.

         Additional   Trials.  In  October  1996,   thymosin  alpha  1  achieved
statistically  significant  results in the treatment of chronic hepatitis B in a
multicenter,  randomized  and  controlled  study  conducted at the University of
Bologna,  Italy.  A total of 33 patients were enrolled and randomly  assigned to
receive either thymosin alpha 1 twice weekly for six months or alpha  interferon
three times weekly for six months. In addition,  15 clinically  similar patients
who had never  been  treated  with  alpha  interferon  were  used as  historical
controls.  All patients were hepatitis B surface antigen (HBsAg)  positive,  HBV
DNA positive,  hepatitis B e-antibody  (HBeAb) positive and had elevated alanine
transaminase (ALT) levels.

         After six months of observation  following treatment,  the investigator
reported that complete  response was observed in seven of the 17 patients in the
thymosin alpha 1 treatment  group,  four of 16 patients in the alpha  interferon
treatment group, and 1 of 15 patients in the historical control group.  Complete
response was defined as ALT normalization and HBV DNA loss. At the completion of
the 12 month study, the response rate of the thymosin alpha 1 treated group, but
not of the alpha  interferon  treated  group,  was  statistically  significantly
higher than the response rate of the control group.  The  researchers  concluded
that thymosin alpha 1 appeared to be a safe and effective  alternative treatment
for HBeAb positive chronic hepatitis.

         A second team of  researchers  in Italy reported the results of an open
label trial to study the efficacy of combination  therapy using thymosin alpha 1
and low dose natural alpha  interferon in 15 patients with chronic  hepatitis B,
including  11 patients  who had  previously  failed  standard  alpha  interferon
therapy.  All 15  enrolled  patients  were  HBsAg and HBV DNA  positive  and had
elevated  ALT levels.  Patients  were treated for six months and followed for an
additional 12 months. Sustained response at 18 months was defined as the absence
of HBV DNA and normal or near normal ALT levels.

         At the conclusion of the 18 month study, nine of the 15 patients showed
sustained  response,  including  six  of 11  patients  who  had  previously  not
responded to standard alpha interferon treatment.  Of the nine responders,  five
patients  seroconverted  to HBeAg  negative  status and two patients  were HBeAg
negative at entry.  In addition,  six of the nine patients  responding  achieved
HBsAg negative status, a long-term marker of clearance in hepatitis B and one of
the final markers to clear in achieving long-term sustained remission.

         There can be no assurance,  however,  that final  audited  results from
these trials will be favorable or statistically  significant.  Further,  even if
the final results from these trials are favorable and statistically significant,
there  can be no  assurance  that  significant  additional  trials  will  not be
required in those and other countries before thymosin alpha 1 is approved in any
such  country  for the  treatment  of  hepatitis  B or that the  results of such
additional trials will be favorable.

         Hepatitis C

         Hepatitis C can be transmitted by blood  transfusions  and contaminated
needles. The mode of transmission in many cases is unknown. Approximately 10% to
20% of  hepatitis  C  carriers  may  develop  cirrhosis,  and up to 40% of these
individuals  may develop liver  cancer.  The incidence of hepatitis C is not yet
fully known, but an article in the Annals of Internal Medicine indicates that in
Japan  alone  there are more than l million  cases of chronic  hepatitis  C. The
Centers for Disease  Control  estimate  that 3.9 million  Americans are infected
with the hepatitis C virus, and the American Liver Foundation  estimates that an
additional 170,000 new cases are reported each year.

         A  randomized,  double-blinded  controlled  phase III study of  chronic
hepatitis C patients receiving  combination therapy consisting of thymosin alpha
1 and alpha  interferon was completed  during 1996 at  Fitzsimmons  Army Medical
Center,  Walter Reed Medical Center and the  University of  Cincinnati.  Patient
enrollment for the trial was completed in January 1996, with final enrollment of
approximately 110 patients. In this study, patients are receiving thymosin alpha
1 and alpha interferon,  alpha interferon alone or placebo for 6 months followed
by 6 months of  observation.  The  combination  of ZADAXIN and alpha  interferon
demonstrated  statistically  significant higher efficacy at the end of treatment
than single agent alpha interferon,  the only currently FDA-approved therapy for
chronic hepatitis C. Among evaluable patients, biochemical response was observed
in 41.9 percent of patients treated with the combination therapy of ZADAXIN plus
alpha interferon, 16.6 percent among patients treated with alpha interferon only
and 2.7 percent  among the patients who received  placebo.  Among  patients with
hepatitis C genotype 1a or 1b, which are the most  resistant to current forms of
treatment,  31 percent of patients treated with  combination  therapy achieved a
biochemical  response  compared  to 12  percent  of  those  treated  with  alpha
interferon only.

         An  additional  study of fifteen  patients  with  chronic  hepatitis  C
conducted by the Institute of Experimental Medicine in Rome achieved significant
results.  All patients enrolled had biopsy confirmed chronic  hepatitis,  raised
ALT values equal to or greater than 1.5 times the upper normal  limit,  positive
serum  hepatitis  C virus  ("HCV  RNA") by  polymerase  chain  reaction  ("PCR")
testing,  and compensated liver disease.  Thirteen patients had HCV RNA genotype
1b  which  in  published  reports  on the  treatment  of  hepatitis  C is  often
associated  with  cirrhosis,  liver cancer and a poor response to treatment with
single  agent alpha  interferon,  currently  the only FDA  approved  therapy for
chronic  hepatits  C. The  patients  in this  trial  received a  combination  of
lymphoblastoid  alpha  interferon  and thymosin alpha 1 therapy for one year and
were followed for an additional six months.  A response to treatment was defined
at 12 months  as a  negative  serum HCV RNA by PCR.  A  sustained  response  was
defined  as a  negative  serum HCV RNA by PCR six  months  after  completion  of
treatment.  After six months of treatment, 47 percent of the patients were found
to be HCV RNA negative.  After one year of treatment, 73 percent of the patients
were HCV RNA negative.  After the six month follow-up  period, 40 percent of the
patients  showed a sustained  response to treatment  and continued to be HCV RNA
negative.  Among the  hepatitis C genotype 1b patients,  69 percent were HCV RNA
negative  after  one year of  treatment  with 39  percent  exhibiting  sustained
response after the six-month follow-up.

         There can be no assurance that significant  additional  trials will not
be required in the United States or other  countries  before thymosin alpha 1 is
approved in such  countries for the treatment of hepatitis C or that the results
of  additional  trials will be  favorable.  In fact,  additional  trials will be
necessary  in the U.S.,  and  approval  is not  assured in the U.S.  or for that
matter, in other countries.

         AIDS

         A large  multicenter  trial of the AZT,  alpha  interferon and thymosin
alpha 1  combination  therapy  in human  immunodeficiency  virus  (HIV)-infected
patients sponsored and funded by the Italian Ministry of Health was completed in
January 1996 after a pilot study at the University of Rome found the combination
of  thymosin  alpha 1 with  alpha  interferon  and AZT was  well  tolerated  and
resulted in a statistically  significant  increase (paired t-test) in CD4 counts
compared  to groups  receiving  AZT  alone or AZT plus  alpha  interferon.  This
multicenter  study was a randomized,  open-label  trial  enrolling  HIV-positive
individuals with CD4+ T cell lymphocyte counts between 500 and 200, asymptomatic
or with AIDS-related  complex,  who had received AZT for no more than one month.
91 patients  were  randomized  into three  treatment  arms:  AZT, AZT plus alpha
interferon,  and AZT plus alpha  interferon and thymosin alpha 1. The results of
this trial found that thymosin  alpha 1  administered  in  combination  with the
anti-viral  drug AZT and alpha  interferon  boosted  the  t-cell  count in HIV -
infected  patients  by a median of 64 points over the  12-month  period with the
other patient groups achieving no clinically relevant increase.

         There can be no assurance,  however,  that the drug will be approved to
treat HIV-infected  patients.  Further, even if approval for thymosin alpha 1 to
treat HIV-infected patients is obtained in Italy, there can be no assurance that
significant  additional trials will not be required in the United States, Europe
or other countries before similar  approvals may be granted in such countries or
that the results of additional trials will be favorable.

CPX

         Cystic Fibrosis

         The  Company   was   cleared  by  the  United   States  Food  and  Drug
Administration  (the "FDA") in January 1997 to begin clinical  studies of its CF
drug, CPX, in the United States.  Under an Investigational  New Drug Application
filed with the FDA in December  1996,  the Company will conduct Phase I clinical
studies  of CPX  directly  in  cystic  fibrosis  patients  rather  than  healthy
volunteers.

         Under the trial  protocol,  developed  in  conjunction  with the Cystic
Fibrosis  Foundation,  patients will be enrolled at five cystic fibrosis centers
in the United  States.  In this Phase I study of CPX,  physicians are seeking to
establish  the  safety and  pharmacokinetic  parameters  of CPX for  determining
optimal dose for  administration  of the drug. In addition,  the physicians also
are  seeking  to  measure  the effect of CPX's  ability  to  normalize  chloride
secretion by defective CF cells via repairing the basic molecular  defect at the
root cause of CF.  There can be no  assurance  that the final  results from this
trial  will be  favorable  or  statistically  significant  or that,  even if the
results of this or subsequent trials are favorable, the drug will be approved to
treat CF patients.

         CF is an inherited  disorder  that affects  about 30,000  people in the
U.S. and 55,000  worldwide.  It is the most common fatal  genetic  defect in the
United  States  today.  CF is caused by a faulty gene that  produces a defective
protein, the function of which is to transport sodium and chloride (salt) within
epithelial  cells  (which  line organs  such as the lungs and  pancreas)  to the
cells' outer surfaces. CF causes the body to produce an abnormally thick, sticky
mucus.  This abnormal mucus clogs the lungs and leads to fatal  infections.  The
thick CF mucus also obstructs the pancreas, preventing enzymes from reaching the
intestines to digest food.  Currently,  there are no known cures for CF, and the
median life expectancy of a CF patient is 30 years of age.

                                      -9-
<PAGE>

         The  Company  may  experience  delays  and  encounter  difficulties  in
clinical trials of CPX. In addition, there can be no assurance that any clinical
trials,   including  those  currently  underway,   will  provide   statistically
significant  evidence  of the  efficacy  of CPX in  treating  any of the  target
diseases.  A failure to  demonstrate  the  efficacy  of CPX in ongoing  clinical
trials, to obtain  additional  approvals or to successfully  commercialize  such
product would have a material adverse effect on the Company.

Marketing and Sales

         SciClone's  international  marketing and sales strategy is to establish
regional   sales  and  marketing   capabilities   and  strategic   alliances  to
commercialize and assist in marketing its pharmaceuticals. The Company currently
has  international  offices  in  Singapore,  Hong Kong,  Taiwan  and  Japan.  If
marketing  approval is received  for ZADAXIN,  the Company  plans to establish a
marketing  program for the drug,  including the  positioning  and pricing of the
drug, and expects that local pharmaceutical  distributors will import, warehouse
and distribute the drug. In Japan,  the Company has licensed SPKK to develop and
market ZADAXIN.

         The  Company  has  established  distribution  arrangements  with  local
pharmaceutical  distribution  companies in over 25  countries,  primarily in the
Asia-Pacific  Region, the Middle East and South America.  However,  no assurance
can be given  that any such  distribution  arrangement  will  remain in place or
prove successful.

         The  Company's  profitability  and financial  condition  will be highly
dependent  on sales in foreign  jurisdictions,  where sales and  operations  are
subject to  inherent  risks,  including  difficulties  and  delays in  obtaining
pricing   approvals  and   reimbursement,   unexpected   changes  in  regulatory
requirements, tariffs and other barriers, political instability, difficulties in
staffing  and  managing  foreign  operations,  longer  payment  cycles,  greater
difficulty  in  accounts  receivable   collection,   currency  fluctuations  and
potential adverse tax consequences.  Certain foreign countries  regulate pricing
of pharmaceuticals and such regulation may result in prices  significantly below
those that would prevail in a free market. In addition,  in many countries where
the Company has  marketing  rights for  ZADAXIN,  government  resources  and per
capita  income  levels  may  be so low  that  the  Company's  products  will  be
prohibitively  expensive  for a  large  percentage  of the  population.  In such
countries,  there can be no  assurance  that the Company will be  successful  in
marketing its products on economically favorable terms, or at all.

Manufacturing

         The  Company   does  not  intend  to   construct  or  operate  its  own
manufacturing  facilities.  Rather,  it intends to source  ZADAXIN,  CPX and any
future  products  through  contract  manufacturing  and supply  agreements.  The
Company  has  entered   into  supply   agreements   with   experienced   peptide
manufacturers in the U.S. and Europe for the supply of bulk thymosin alpha 1 and
has established an inventory sufficient to fulfill its expected  requirements in
the near term. The Company is in the process of negotiating an arrangement  with
another  manufacturer  for the final  manufacture  and packaging of ZADAXIN upon
supply of bulk drug. The Company currently contracts with a major pharmaceutical
Company for the supply of bulk CPX and another manufacturer for the packaging of
CPX upon supply of bulk drug.

         The Company has  experienced  delays of supply of thymosin alpha l bulk
drug in the past and  could do so again in the  future.  To be  successful,  the
Company's  products must be manufactured in commercial  quantities in compliance
with regulatory  requirements and at acceptable cost. While the Company believes
it has and will be able in the future to establish  manufacturing  relationships
with suppliers  experienced in 

                                      -10-

<PAGE>

their businesses, there can be no assurance that the Company will establish long
term  manufacturing  relationships  with suppliers or that these  suppliers will
prove satisfactory. Production interruptions, if they occur, could significantly
delay clinical development of potential products, reduce third party or clinical
researcher  interest and support of proposed clinical trials, and possibly delay
commercialization of such products and impair their competitive position,  which
would have a material adverse effect on the business and financial  condition of
the Company.

Sponsored Research and Development

         For the years  ended  December  31,  1996,  1995 and 1994,  the Company
expended  $9,904,000,  $10,386,000  and  $9,282,000,  respectively,  in  Company
sponsored research and development activities (excluding any special charges).

Competition

         Competition  in the  pharmaceutical  field is intense  and the  Company
expects that competition will increase.  The Company's competitors include major
pharmaceutical  companies,   biotechnology  firms  and  universities  and  other
research  institutions,  both in the United States and abroad, that are actively
engaged in research and development of products in the  therapeutic  areas being
pursued  by  the  Company.   Many  of  these  companies  and  institutions  have
substantially greater financial, technical,  manufacturing,  marketing and human
resource  capabilities than the Company and extensive  experience in undertaking
clinical testing and obtaining  regulatory  approvals necessary to market drugs.
Principal  competitive  factors in the  pharmaceutical  field include  efficacy,
safety, and therapeutic regimen. Where comparable products are marketed by other
companies price is also a competitive  factor.  The Company intends to use alpha
interferon as a reference  drug in  establishing  pricing for ZADAXIN,  although
this may change over time.

Government Regulation

         Regulation by governmental authorities in the United States and foreign
countries  is a  significant  factor in the  manufacturing  of products  for the
Company and the  marketing of products by the Company,  in ongoing  research and
development  activities  and in  preclinical  and  clinical  trials and  testing
related to the Company's  products.  If the Company's products are manufactured,
tested or sold in the United States,  they will be regulated in accordance  with
the  Federal  Food,  Drug  and  Cosmetic  Act.  If the  Company  were to  market
biologics,  such products would be regulated  under both the Federal Food,  Drug
and  Cosmetic  Act and the Public  Health  Service  Act.  The  standard  process
required by the FDA before a pharmaceutical  agent may be marketed in the United
States includes (i) preclinical  laboratory and animal tests, (ii) submission to
the FDA of an application  for an  investigational  new drug exemption  ("IND"),
which must become  effective  before human clinical  trials may commence,  (iii)
adequate  well-controlled  human  clinical  trials to  establish  the safety and
efficacy of the product for its intended indication,  (iv) submission to the FDA
of a New Drug  Application  ("NDA") with respect to drugs and a Product  License
Application  ("PLA") with respect to biologics,  and (v) FDA approval of the NDA
or PLA prior to any  commercial  sale or  shipment of the drug or  biologic.  In
addition to obtaining FDA approval for each product, each domestic manufacturing
establishment  must be  registered  with the FDA.  For  biologic  products,  the
manufacturer  must also  submit  and  obtain FDA  approval  of an  Establishment
License  Application  ("ELA").  It is the FDA's practice in cases of approval to
approve the PLA for a product and the ELA for the facility that will manufacture
the product at the same time. Until approval of both the PLA and ELA, commercial
marketing  of a biologic  may not begin.  For  certain  biologic  products,  FDA
requires  approval  of  only a  single  license  application,  referred  to as a
Biologic  License  Application  (BLA).  For drugs  subject  to the NDA  approval
process, commercial marketing may not begin until the NDA is approved. Domestic

                                      -11-
<PAGE>

manufacturing  establishments are subject to inspections by the FDA and by other
federal,  state and local  agencies and must comply with current  United  States
Good Manufacturing Practices ("GMP").

         In the United  States,  clinical  trial  programs  generally  involve a
three-phase process.  Typically,  phase I pharmacology trials are conducted in a
small number of healthy  volunteers to determine  the toxicity,  pharmacological
effects,  metabolism and dose range  requirements  for the drug. Phase II trials
are conducted with groups of patients  afflicted with the target disease to make
a  preliminary  determination  of efficacy  and  optimal  dosages and to provide
additional  evidence  of  safety.  In  phase  III,   large-scale,   multi-center
comparative  trials are conducted in patients  afflicted with the target disease
to provide  sufficient  data for the  statistical  proof of efficacy  and safety
required  by  the  FDA  and  other  regulatory  agencies.  The  results  of  the
preclinical and clinical  testing are submitted to the FDA in the form of an NDA
or PLA for approval to commence  commercial  sales.  In  responding to an NDA or
PLA, the FDA may grant  marketing  approval or deny the  application  if the FDA
determines  that  the  application  does not  satisfy  its  regulatory  approval
criteria. In approving an NDA or PLA, the FDA may require further post-marketing
studies, referred to as phase IV studies. When used in this Report in connection
with trials and filings in other countries, terms such as "phase I," "phase II,"
"phase  III,"  "phase IV" and "new drug  application"  refer to what the Company
believes are comparable trials and filings in such other countries.

         The FDA has issued  regulations  intended to  accelerate  the  approval
process  for  the  development,  evaluation  and  marketing  of new  therapeutic
products intended to treat  life-threatening or severely  debilitating  illness,
especially where no satisfactory  alternative therapies exist. These regulations
provide for early consultation  between the sponsor and the FDA in the design of
both preclinical and clinical testing  procedures.  These  regulations allow for
phase I clinical  studies to be carried out in  patients  rather than in healthy
volunteers, as is customary,  followed by studies to establish efficacy in phase
II trials.  If the results of the phase I and phase II trials support the safety
and efficacy of the therapeutic  agent and their design and execution are deemed
satisfactory upon review by the FDA, marketing approval can be sought at the end
of  the  phase  II  trials.  If  applicable,  this  procedure  may  shorten  the
traditional  drug  development  process in the United States by an estimated 2-3
years. Notwithstanding the foregoing, approval may be denied by the FDA or phase
III trials may be required.  The FDA may also seek an  applicant's  agreement to
perform post-approval phase IV studies.

         Even after  initial FDA approval has been  obtained,  further  studies,
including  post-marketing studies, may be required to provide additional data on
safety  and will be  required  to gain  approval  for the use of a product  as a
treatment  for clinical  indications  other than those for which the product was
initially tested. Also, the FDA will require post-marketing reporting to monitor
the side effects of the drug or biologic. Results of post-marketing programs may
limit or expand the further marketing of the products. Further, if there are any
modifications  to  the  drug  or  biologic,  including  changes  in  indication,
manufacturing process,  labeling, or a change in manufacturing  facility, an NDA
or PLA supplement may be required to be submitted to the FDA.

         The  Orphan  Drug Act of 1983,  as amended  (the  "Orphan  Drug  Act"),
provides  incentives to drug  manufacturers to develop and manufacture drugs for
the treatment of rare diseases,  currently defined as diseases that affect fewer
than  200,000  individuals  in the United  States or, for a disease that affects
more than 200,000  individuals in the United States,  where the sponsor does not
realistically anticipate its product becoming profitable.  Under the Orphan Drug
Act, a manufacturer  of a designated  orphan product can seek tax benefits,  and
the holder of the first FDA  approval of a  designated  orphan  product  will be
granted a seven year period of  marketing  exclusivity  for that product for the
orphan  indication.  While the  marketing  exclusivity  of an orphan  drug would
prevent other sponsors from obtaining approval of the same compound for the same
indication,  it would not prevent  other types of drugs from being  approved for
the same use.  

                                      -12-

<PAGE>

Legislation  may be introduced in the United States Congress that would restrict
the duration of the market  exclusivity  of an orphan drug,  and there can be no
assurances that the benefits of the existing statute will remain in effect.

         Under the Drug Price  Competition  and Patent Term  Restoration  Act of
1984,  a  sponsor  may be  granted  marketing  exclusivity  for a period of time
following  FDA  approval  of certain  drug  applications,  regardless  of patent
status,  if the drug is a new chemical entity or new clinical  studies were used
to support the marketing application. This marketing exclusivity would prevent a
third party from  obtaining FDA approval for a similar or identical drug through
an Abbreviated New Drug  Application  ("ANDA"),  which is the  application  form
typically used by manufacturers  seeking approval of a generic drug. The statute
also allows a patent  owner to extend the term of the patent for a period  equal
to  one-half  the period of time  elapsed  between  the filing of an IND and the
filing of the  corresponding  NDA plus the period of time  between the filing of
the NDA and FDA  approval  with the  maximum  patent  extension  term being five
years.  The Company may seek the benefits of this  statute,  but there can be no
assurance that the Company will be able to obtain any such benefits.

         The Company is subject to foreign regulations  governing human clinical
trials and  pharmaceutical  sales.  The  requirements  governing  the conduct of
clinical trials,  product licensing,  pricing and reimbursement vary widely from
country to country. Whether or not FDA approval has been obtained, approval of a
product  by the  comparable  regulatory  authorities  of  foreign  countries  is
required  prior  to the  commencement  of  marketing  of the  product  in  those
countries.  The  approval  process  varies from  country to country and the time
required  for  approval  may be longer or  shorter  than that  required  for FDA
approval.  In general,  foreign  countries  use one of three forms of regulatory
approval process.  In one form, local clinical trials must be undertaken and the
data must be compiled  and  submitted  for review and  approval.  In Japan,  for
example,  the process is  time-consuming  and costly because all clinical trials
and most  preclinical  studies  must be  conducted  in Japan.  A second  form of
approval process requires clinical trial submissions, but permits use of foreign
clinical  trials and typically also requires some form of local trial as well. A
third form of approval  process  does not require  local  clinical  trials,  but
rather contemplates  submission of an application including proof of approval by
countries that have clinical trial review procedures.  Thus, a prior approval in
one or more of the United States,  Japan, most European  countries or Australia,
among others,  is often  sufficient  for approval in countries  using this third
form of approval process.

         In addition to required foreign approvals, the FDA regulates the export
of drugs or bulk  pharmaceuticals  from the United States. In general, a drug or
biologic that has been approved for commercial  sale in the United States may be
exported for commercial sale. In 1996,  export reform  legislation was passed in
the United  States that  provides  that an  unapproved  drug or biologic  may be
exported  to  a  "listed  country"  for  investigational   puposes  without  FDA
authorization.  The listed countries are Australia,  Canada,  Israel, Japan, New
Zealand, Switzerland,  South Africa, and countries in the European Union and the
European  Economic Area. Export of drugs or biologics to an unlisted country for
clinical trial purposes  continues to require FDA approval,  either under an IND
or pursuant to a written  request  from either the person  seeking to export the
product or from the foreign country to which the product is to be exported.  The
Company has obtained,  where necessary,  FDA approval for all exports of ZADAXIN
from the United  States to date for clinical  trial  purposes,  and will seek to
obtain FDA approval,  where necessary,  for any future shipments from the United
States. The export reform  legislation  further provides that an unapproved drug
or biologic can be exported to any country for commercial purposes without prior
FDA approval,  provided that the drug or biologic: (i) complies with the laws of
that country; and (ii) has valid marketing  authorization or the equivalent from
the appropriate  authority in a "listed  country."  Export of drugs or biologies
that do not have marketing authorization in a listed country continue to require
FDA export approval.

                                      -13-

<PAGE>

         Pursuant  to the  Prescription  Drug  User  Fee Act of  1992,  drug and
biologic  manufacturers  are  required  to pay three  types of user fees:  (1) a
one-time  application  fee for approval of an NDA or PLA; (2) an annual  product
fee imposed on prescription drug and biologic  products after FDA approval;  and
(3) an annual  establishment  fee  imposed  on  facilities  used to  manufacture
prescription  drugs or  biologics.  The fee  rates for 1997  are:  (1)  $205,000
one-time fee for an application  requiring clinical data, or $102,500 fee for an
application not requiring clinical data; (2) $115,700 annual  establishment fee;
and (3) $13,200  annual product fee. These fee amounts are likely to increase in
the future.

         Among the  conditions  for NDA or PLA approval in the United  States is
the  requirement  that  the  prospective   manufacturer's  quality  control  and
manufacturing  procedures  conform to GMP. In complying with standards set forth
in these  regulations,  manufacturers  must  continue to expend time,  money and
effort in the area of production  and quality  control to ensure full  technical
compliance.

         The Company is also subject to various  federal,  state and local laws,
regulations and recommendations relating to safe working conditions,  laboratory
and  manufacturing  practices,  the  experimental use of animals and the use and
disposal of hazardous or potentially hazardous substances, including radioactive
compounds and infectious  disease agents,  used in connection with research work
and  preclinical  and  clinical  trials and  testing.  The extent of  government
regulation which might result from future  legislation or administrative  action
in these areas cannot be accurately predicted.

         As  the  preceding  discussion  indicates,  the  research,  preclinical
development,   clinical   trials,   manufacturing,   marketing   and   sales  of
pharmaceuticals,  including ZADAXIN and CPX, are subject to extensive regulation
by  governmental  authorities.  Products  developed  by the  Company  cannot  be
marketed  commercially in any jurisdiction in which they have not been approved.
The process of obtaining regulatory approvals is lengthy, uncertain and requires
the expenditure of substantial  resources.  For example, in some countries where
the Company contemplates  marketing ZADAXIN, the regulatory approval process for
drugs not previously approved in countries that have established  clinical trial
review  procedures  is uncertain  and this  uncertainty  may result in delays in
granting regulatory approvals.  In addition, in certain countries such as Japan,
the process for  obtaining  regulatory  approval  is time  consuming  and costly
because all  clinical  trials and most  preclinical  studies  must be  conducted
there. The Company is currently  pursuing  regulatory  approvals of ZADAXIN in a
number of  countries,  but  there  can be no  assurance  that the  Company  will
ultimately  obtain  approvals in such  countries in a timely and  cost-effective
manner or at all. The  marketing  approval  for ZADAXIN in Singapore  requires a
patient  surveillance  program  to  continue  study  of the  drug's  safety  and
efficacy.  Adverse  results in such  program  could  result in the  placement of
restrictions  on the use of ZADAXIN or  revocation of the approval in Singapore.
Failure  to  comply  with  applicable   United  States  or  foreign   regulatory
requirements can, among other things, result in fines, suspensions of regulatory
approvals, product recalls or seizures, operating restrictions,  injunctions and
criminal  prosecutions.   Further,   additional  government  regulation  may  be
established or imposed by legislation or otherwise  which could prevent or delay
regulatory approval of ZADAXIN or any future products of the Company.

Third Party Reimbursement

         The Company's  ability to successfully  commercialize  its products may
depend  in  part on the  extent  to  which  reimbursement  for the  cost of such
products will be available from government  health  administration  authorities,
private health insurers and other organizations.  Significant uncertainty exists
as to the reimbursement  status of new therapeutic  products and there can be no
assurance  that third party  reimbursement  will be  available  for  therapeutic
products the Company might  develop.  In many of the foreign  countries in which
the Company  intends to operate,  reimbursement  of ZADAXIN under  government or
private health insurance  programs will not be available.  In the United States,
health care reform is an area of increasing national attention and a

                                      -14-
<PAGE>

priority of many governmental  officials.  Certain reform proposals, if adopted,
could impose limitations on the prices the Company will be able to charge in the
United States for its products or the amount of  reimbursment  for the Company's
products from governmental agencies or third party payors.

Patents and Proprietary Rights

         Pharmaceuticals  are not patentable in certain  countries in SciClone's
ZADAXIN territory,  or have only recently become patentable,  and enforcement of
intellectual  property  rights  in many  countries  in such  territory  has been
limited or non-existent.  Future enforcement of intellectual  property rights in
many countries in SciClone's ZADAXIN territory can be expected to be problematic
or unpredictable.

         The Company is the exclusive  licensee  (with limited  exceptions) of a
number of foreign patents directed to the thymosin alpha 1 composition of matter
which is owned by Hoffman-La Roche AG and the Board of Regents of the University
of Texas System.  The majority of these foreign patents are due to expire in the
late 1990's.  SciClone's rights to these patents emanate from license agreements
from  Hoffman-La  Roche AG to Alpha 1, and the  August  1994  license  agreement
between Alpha 1 and SciClone.  Within the Company's  territory,  composition  of
matter  protection for thymosin alpha 1 exists in Canada, a majority of European
countries,  Japan, Australia, New Zealand,  Singapore, the Philippines and South
Africa.  The Company is currently  seeking a patent term  extension in Australia
and is exploring the  feasibility of extending  patent terms in Europe.  Process
patents  owned by Alpha 1 and  exclusively  licensed to SciClone are directed to
methods of making  thymosin  alpha 1 and have  issued in a majority  of European
countries and Taiwan. Other composition, process and use patent applications are
pending in countries in  SciClone's  territory.  In addition,  patents for which
Alpha 1 is a co-patentee covering the use of thymosin alpha 1 to treat hepatitis
C have issued in Taiwan, Australia,  South Africa and have recently been allowed
in many  European  countries.  Patents  under which  SciClone  is licensed  have
issued: in the United States and Australia  covering the use of thymosin alpha 1
to treat small cell and non-small cell lung cancer; in the United States,  South
Africa and  Taiwan  covering  the use of  thymosin  alpha 1 to treat  autoimmune
hepatitis; in Japan covering the treatment of chronic hepatitis B using thymosin
alpha 1; in Taiwan  covering the use of thymosin  alpha 1 to treat septic shock;
and in Taiwan  and  South  Africa  covering  the  treatment  of  infertility  in
mammalian  males using thymosin alpha 1. Patents which SciClone owns have issued
in the United States, Taiwan and South Africa covering the use of thymosin alpha
1 to treat hepatitis B carriers with minimal disease.

         The  Company  is the  exclusive  licensee  of an  issued,  U.S.  patent
coverning  the use of CPX to treat  cystic  fibrosis,  as well as other  pending
domestic and foreign patent applications covering CPX analogues and their use in
treating cystic fibrosis.

         The  Company's  success is  significantly  dependent  on its ability to
obtain patent  protection for its products and  technologies and to preserve its
trade secrets and operate without  infringing on the proprietary rights of third
parties.   No  assurance  can  be  given  that  the  Company's   pending  patent
applications  will result in the  issuance  of patents or that any patents  will
provide competitive advantages or will not be invalidated or circumvented by its
competitors. Moreover, no assurance can be given that patents are not issued to,
or patent  applications have not been filed by, other companies which would have
an adverse  effect on the Company's  ability to use,  manufacture  or market its
products or maintain its  competitive  position  with  respect to its  products.
Other companies  obtaining  patents claiming products or processes useful to the
Company may bring  infringement  actions against the Company.  As a result,  the
Company may be required  to obtain  licenses  from others or not be able to use,
manufacture  or market its  products.  Such  licenses  may not be  available  on
commercially reasonable terms, if at all.

         The  patent  positions  of  biotechnology  firms  generally  are highly
uncertain and involve complex legal and factual questions.  No consistent policy
has emerged regarding the validity and scope of claims in biotechnology patents,
and courts have issued  varying  interpretations  in the recent past,  and legal
standards   concerning   validity,   scope  and  interpretations  of  claims  in
biotechnology  patents may continue to evolve.  Even issued patents may later be
modified or revoked by the U.S. Patent and Trademark Office, the European Patent
Office or the courts in proceedings  instituted by third parties.  Moreover, the
issuance  of a patent in one  country  does not assure the  issuance of a patent
with similar claims in another country and claim interpretation and infringement
laws vary among countries,  so the extent of any patent  protection is uncertain
and may vary in different countries.

         In addition  to patent  protection,  the  Company  intends to use other
means to protect its proprietary rights. A type of marketing  exclusivity period
may be available under regulatory  provisions in certain countries including the
United States,  European Union Countries,  Japan and Taiwan,  which benefits the
holder  of the first  marketing  approval  for new  chemical  entities  or their
equivalents for a given indication.  Orphan drug protection will be sought where
available granting additional market  exclusivity.  The Company is the holder of
an orphan drug product  designation for thymosin alpha 1 for chronic hepatitis B
in the United States.  Recognition  and protection of trademarks for the product
is being accomplished through a world-wide filing of trademark  applications for
ZADAXIN and other  trademarks  which will appear on the commercial  packaging of
the  product  and will be used in  promotional  literature.  Copyrights  for the
commercial  packaging  may  provide  SciClone  with means to take  advantage  of
procedures  available in certain  countries to exclude  counterfeit  products or
genuine but unauthorized products from entering a particular country by parallel
importation. The Company also expects to implement  anti-counterfeiting measures
on  commercial  packaging  as well as  registration  of  packaging  with customs
departments in countries  where such  procedures  exist.  The Company intends to
pursue similar types of protection for CPX.

         The Company also relies upon trade secrets,  which it seeks to protect,
in part, by confidentiality  agreements with employees,  consultants,  suppliers
and  licenses.  There can be no  assurance  that  these  agreements  will not be
breached,  that  SciClone  would have  adequate  remedies for any breach or that
SciClone's  trade  secrets  will not  otherwise  become  known or  independently
developed by competitors.

Employees

         As of December 31, 1996, the Company had 36 employees, 25 in the United
States and 11 abroad.  The Company considers its relations with its employees to
be satisfactory.

Item 2.    Properties

         The Company has leased approximately 14,000 square feet of office space
at its  headquarters  in San Mateo,  California  and  limited  office  space for
marketing  purposes  in  Singapore,  Hong Kong,  Taiwan and Japan.  The  Company
believes  that its existing  facilities  are adequate for its current  needs and
that additional space will be available as needed.

Item 7.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations

         The Company is an international  biopharmaceutical  company involved in
the acquisition, development and commercialization of pharmaceuticals worldwide.
The Company focuses on specialist  oriented products that address  significantly
unmet  chronic  or  life-threatening   diseases.  The  Company  concentrates  on
infectious diseases, such as hepatitis B and C, cancer, immune system disorders,
and  cystic  fibrosis.  Currently,  the  Company  has  acquired  two  drugs  for
development and commercialization:  ZADAXIN(R) thymosin alpha 1, for hepatitis B
and C, cancer and immune system disorders; and CPX for cystic fibrosis. To date,
the Company's principal focus has been the development and  commercialization of
ZADAXIN.

         From commencement of operations  through December 31, 1996, the Company
incurred a  cumulative  net loss of  approximately  $71.4  million.  The Company
expects its  operating  expenses to increase  over the next several  years as it
expands  its  research  and   development,   clinical   testing  and   marketing
capabilities.   The  Company's  ability  to  achieve  profitable  operations  is
primarily dependent on securing  regulatory  approvals for ZADAXIN in additional
countries,  successfully  launching  ZADAXIN once approved and meeting increased
demand for ZADAXIN, if it arises. In addition, other factors may also impact the
Company's ability to achieve a profitable level of operations such as successful
development of CPX,  acquiring rights to additional drugs, and entering into and
extending  agreements  for  product  development  and  commercialization,  where
appropriate.  There can be no assurance  that the Company will be able to attain
these  objectives  or that the Company will ever  achieve a profitable  level of
operations.

         The Company's  operating results may fluctuate from period to period as
a result of, among other things,  the timing and costs  associated with clinical
trials and the regulatory  approval  process,  and the acquisition of additional
product rights.  The Company  participates in a highly dynamic  industry,  which
often results in  significant  volatility  of the Company's  common stock price.
Setbacks  in  clinical  trials,  in  the  regulatory   approval  process  or  in
relationships  with  collaborative  partners,  and any  shortfalls in revenue or
earnings from levels expected by securities analysts,  among other developments,
have in the past had and could in the future have an immediate  and  significant
adverse  effect on the trading price of the Company's  common stock in any given
period.

Results of Operations

         Product  sales were  approximately  $703,000 and $273,000 for the years
ended December 31, 1996 and 1995, respectively.  There were no product sales for
1994.  Currently,  the Company has received approval to market ZADAXIN in China,
the Philippines and Singapore.  In addition,  the Company has filed for approval
to market ZADAXIN in several  countries and  anticipates  additional  filings in
other countries.  As a result,  the Company expects product sales to increase in
1997 and beyond,  upon the  commencement of the commercial  launch of ZADAXIN in
its existing approved markets and additional  markets once regulatory  approvals
are  secured.  The  level of such  product  sales  increase  is  dependent  upon
additional  ZADAXIN  marketing  approvals and  successfully  launching  ZADAXIN.
Although the Company  remains  optimistic  regarding  the  prospects of ZADAXIN,
there can be no assurance  that the Company will achieve  significant  levels of
product sales.

         Cost of product sales was  approximately  $740,000 and $737,000 for the
years  ended  December  31,  1996 and 1995,  respectively.  There was no cost of
product  sales  for  1994.  Cost of  product  sales in 1996  and 1995  primarily
consists of the fixed costs associated with acquiring and warehousing  inventory
and, to a lesser extent,  the direct  product cost. The Company  expects cost of
product  sales to vary from  quarter  to  quarter,  dependent  upon the level of
product sales and the absorption of fixed product-related costs.

         Research  and  development  expenses  were  approximately   $9,904,000,
$10,386,000,  and $12,752,000  for the years ended December 31, 1996,  1995, and
1994,  respectively.  For the year ended  December  31,  1996,  the  decrease in
research and development expenses as compared to 1995 was primarily attributable
to  decreases in  regulatory  expenses and in costs  associated  with  decreased
ZADAXIN clinical trials, essentially due to the completion of the ZADAXIN Taiwan
Phase III  Hepatitis B trial during the first half of 1996,  offset by increased
preclinical development expenses associated with CPX. In April 1996, the Company
acquired an  exclusive  license to CPX, a synthetic  compound  developed  by the
National Institutes of Health as a potential treatment for cystic fibrosis.  The
Company has incurred additional preclinical development expenses to initiate the
clinical development of this compound. For the year ended December 31, 1995, the
decrease in research and development  expenses as compared to 1994 was primarily
attributable to a one-time special charge of $3,470,000 related to the Company's
acquisition of U.S. and European thymosin alpha 1 rights under an agreement with
Alpha 1 Biomedicals,  Inc. ("Alpha 1") in 1994. This 1995 decrease was offset by
increased  professional service expenses,  primarily consulting fees, associated
with  ZADAXIN  development  activities  in the U.S.  and Europe.  The Company is
currently  finalizing its U.S. and European  ZADAXIN clinical trial strategy and
the  results of this  review  will have a  significant  effect on the  Company's
research and development expenses in the future. In addition,  the Company plans
to  initiate  clinical  trials  for CPX in 1997,  which  will  have an impact on
research and development  expenses. In general, the Company expects research and
development expenses to increase over the next several years and to vary quarter
to quarter as the Company pursues its strategy of initiating additional clinical
trials  and  testing,   acquiring  product  rights,  and  expanding   regulatory
activities.


                                      -21-

         Marketing  expenses  were  approximately  $4,240,000,  $4,323,000,  and
$4,375,000 for the years ended December 31, 1996, 1995, and 1994,  respectively.
The decrease in 1996 as compared to 1995 is primarily  attributable to decreased
payroll  costs  related to an  executive  officer  who left the Company in 1995,
offset  by  increased  professional  services,   primarily  consulting  services
expenses,  regarding  preparations  for the launch of  ZADAXIN  in its  approved
markets in early 1997.  The  decrease in 1995 as compared to 1994 was  primarily
attributable to decreased  professional  services  related to ZADAXIN  marketing
activities  and  materials  offset  by  increased  personnel  costs,   primarily
associated  with  severance  costs related to an executive  officer who left the
Company  in  1995.   The  Company   expects   marketing   expenses  to  increase
significantly in the next several quarters and years as it anticipates expanding
its  commercialization  and  marketing  efforts  and  pursuing  other  strategic
relationships.

         General and  administrative  expenses  were  approximately  $3,183,000,
$2,904,000,  and  $3,811,000  for the years ended  December 31, 1996,  1995, and
1994,  respectively.  The  increase  in 1996 as  compared  to 1995 is  primarily
attributable  to  increased  payroll  costs  offset by  decreased  expenses  for
professional  services,  primarily  legal  services  and  consulting  fees.  The
decrease in 1995 from 1994 was primarily  attributable to decreased professional
service  expenses,  primarily  legal services  associated with a 1994 securities
class action  lawsuit and the  Company's  1994 legal  proceedings  with Alpha 1.
These  legal   proceedings   were   completed  in  early  1995  and  late  1994,
respectively.  In the near term, the Company expects general and  administrative
expenses  to vary  quarter to quarter as the  Company  augments  its general and
administrative  activities to support increased  expenditures on clinical trials
and testing, and regulatory, pre-commercialization and marketing activities.

         Net  interest  and  investment  income  was  approximately  $2,618,000,
$3,302,000,  and  $3,057,000  for the years ended  December 31, 1996,  1995, and
1994,  respectively.  The  decrease in 1996 as compared  to 1995  resulted  from
decreased  interest and  investment  income due to lower  average  invested cash
balances.  The  increase  in 1995 as  compared  to 1994  resulted  from  overall
increased  interest  rates  during  1995 and  gains  from  the  sale of  certain
short-term  investments  offset  by lower  average  invested  cash  balances  as
compared to 1994.

Liquidity and Capital Resources

         Prior to the Company's initial public offering, the Company's principal
sources of funds were equity and debt private  placements,  salary  deferrals by
officers and funds advanced by officers.  In March 1992,  the Company  completed
its initial  public  offering of 3,450,000  shares of common stock and 3,450,000
redeemable  warrants  to  purchase  common  stock,  receiving  net  proceeds  of
approximately  $21,774,000.  In August 1993, the Company received  approximately
$38,100,000  in net  proceeds  from the  exercise  of  substantially  all of the
Company's 4,258,231  outstanding  Redeemable Warrants,  which the Company called
for  redemption in July 1993. In January  1994,  the Company  completed a public
offering  of  2,000,000  shares of  common  stock,  receiving  net  proceeds  of
approximately $43,600,000.

         At  December  31,  1996,  and  1995,  the  Company  had   approximately
$35,106,000  and  $47,390,000,   respectively  in  cash,  cash  equivalents  and
marketable  securities.  The marketable  securities  consist primarily of highly
liquid short-term and long-term investments.

         Net cash  used by the  Company  in  operating  activities  amounted  to
approximately  $14,641,000,  $17,098,000,  and $12,909,000,  for the years ended
December  31,  1996,  1995,  and 1994  respectively.  Net cash used in operating
activities  for the year ended  December 31, 1996 is less than the Company's net
loss  for  such  period  primarily  due  to  noncash  charges   associated  with
depreciation   of  furniture  and  equipment   and   amortization   of  deferred
compensation in addition to increases in amounts owed to third parties for 


                                      -22-

goods  and  services.  These  amounts  were  partially  offset  by cash used for
inventory  purchases,  increases in and  prepayments  of certain  future  period
expenses and payments of amounts owed to third parties related to clinical trial
expenses and  compensation and benefits.  Net cash used in operating  activities
for the year ended December 31, 1995 was greater than the Company's net loss for
such period primarily due to cash used for inventory  purchases,  the prepayment
of certain future period  expenses and increases in accounts  receivable.  These
cash uses were  partially  offset by increases in amounts owed to third  parties
for goods and services related to clinical trial expenses in addition to noncash
charges  associated  with  depreciation  and  amortization.  Net  cash  used  in
operating  activities  for the year  ended  December  31,  1994 is less than the
Company's net loss for such period  primarily due to noncash charges  associated
with   depreciation  of  furniture  and  equipment,   amortization  of  deferred
compensation,  and acquisition of in-process technology in addition to increases
in amounts owed to third parties for clinical trials,  compensation and benefits
and goods and  services.  These  amounts were  partially  offset by increases in
payments for accrued professional fees.

         Net cash provided by investing  activities  for the year ended December
31,  1996  primarily  related to the net sale of  approximately  $12,319,000  in
marketable  securities  offset  by the  purchase  of  approximately  $94,000  in
equipment and furniture.  Net cash provided by investing activities for the year
ended  December  31,  1995  primarily  related to the net sale of  approximately
$14,729,000  in marketable  securities  offset by the purchase of  approximately
$204,000 in equipment and furniture.  Net cash used in investing  activities for
the year ended  December  31,  1994  primarily  related to the net  purchase  of
approximately   $18,957,000  in  marketable   securities  and  the  purchase  of
approximately $113,000 in equipment and furniture.

         Net cash provided by financing  activities  for the year ended December
31, 1996  related to  approximately  $3,731,000  in proceeds  received  from the
issuance  of common  stock  under the  Company's  stock  option  plan  offset by
approximately  $659,000 related to Company's repurchase of its common stock. Net
cash used in financing  activities  for the year ended December 31, 1995 related
to the  Company's  repurchase  of  approximately  $1,925,000 of its common stock
offset by  approximately  $192,000 in  proceeds  received  from the  issuance of
common  stock  under the  Company's  stock  option  plan.  Net cash  provided by
financing   activities   for  the  year  ended  December  31,  1994  related  to
approximately $44,731,000 in net proceeds received from the sale of common stock
in a public  offering  and proceeds  received  from the issuance of common stock
under the  Company's  stock option plan offset by the  Company's  repurchase  of
approximately $7,798,000 of its common stock.

         Management  believes its  existing  capital  resources  and interest on
funds  available are adequate to maintain its current and planned  operations at
least  through 1998.  However,  the Company's  capital  requirements  may change
depending upon numerous  factors,  including the level of ZADAXIN product sales,
the availability of  complementary  products,  technologies and businesses,  the
results of clinical  trials and  testing,  the timing of  regulatory  approvals,
developments  in  relationships  with  collaborative  partners and the status of
competitive products. If the Company cannot eventually generate sufficient funds
from  operations,  it will need to raise additional  financing.  There can be no
assurance that such financing will be available on acceptable terms, or at all.

         In October  1995,  the  Financial  Accounting  Standards  Board  issued
Statement of Financial  Accounting  Standards No. 123 ("SFAS 123"),  "Accounting
for Stock-Based  Compensation."  As permitted by SFAS 123, the Company  accounts
for its stock option and employee  stock  purchase plans under the provisions of
Accounting  Principles Board Opinion 25 ("APB 25") and related  Interpretations.
Accordingly,  the Company does not recognize  compensation expense in accounting
for its stock option and stock  purchase plans for awards which have an exercise
price equal to the fair value of the  Company's  common stock on the date of the
grant.

Factors That May Affect Future Results

         The  material   contained  herein  contains   certain   forward-looking
statements, including statements regarding the application of ZADAXIN in disease
areas beyond hepatitis B, the potential for regulatory  approvals of ZADAXIN and
the launching of ZADAXIN in additional markets,  and the Company's  expectations
regarding  increases  in revenues  from ZADAXIN and  increases in marketing  and
research and development expense levels. These statements are subject to certain
risks and  uncertainties.  These risks and  uncertainties  include the Company's
reliance on a single product, ZADAXIN(R) thymosin alpha 1, for its revenues, the
absence  of  regulatory  approval  for  ZADAXIN  in  significant   markets,  the
expensive,  time  consuming and uncertain  regulatory  approval  process,  risks
associated  with the manufacture  and supply of ZADAXIN,  and  competition  from
competing  therapies,  uncertainties  regarding  the  outcome  of the  Company's
efforts  to  commercialize  additional  products,  as well as  other  risks  and
uncertainties described herein and in the Company's other reports filed with the
Securities and Exchange Commission.

                   Notes to Consolidated Financial Statements


Note 1 - The Company and Summary of Significant Accounting Policies

The Company

         SciClone  Pharmaceuticals,  Inc.  ("SciClone"  or the  "Company") is an
international biopharmaceutical company involved in the acquisition, development
and  commercialization  of  pharmaceuticals  worldwide.  The Company  focuses on
specialist  oriented  products  that  address  significantly  unmet  chronic  or
life-threatening diseases. The Company concentrates on infectious diseases, such
as hepatitis B and C, cancer,  immune  system  disorders,  and cystic  fibrosis.
Currently,   the   Company  has   acquired   two  drugs  for   development   and
commercialization:  ZADAXIN(R)  thymosin  alpha 1, for hepatitis B and C, cancer
and immune system disorders; and CPX for cystic fibrosis. To date, the Company's
principal focus has been the development and commercialization of ZADAXIN.

Basis of Presentation

         The  consolidated  financial  statements  include  the  accounts of the
Company and its wholly owned subsidiaries. All significant intercompany accounts
and transactions have been eliminated

Use of Estimates

         The  preparation of financial  statements in conformity  with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that affect the amounts  reported in the financial  statements  and
accompanying notes. Actual results could differ from those estimates.

Cash Equivalents and Investments

         Cash  equivalents  consist of highly liquid  investments with remaining
maturities  of three months or less.  All cash  equivalents  are carried at cost
plus accrued interest, which approximates market.

         The  Company  has  classified  its  entire  investments   portfolio  as
available-for-sale and records these investments at fair value, as determined by
available  market  information,  on the balance sheet.  The portfolio  primarily
consists of U.S. Government securities and short-term and long-debt instruments.
Unrealized  holding  gains or losses  are  carried as a  separate  component  of
shareholders'  equity.  The  amortized  cost of debt  securities  classified  as
available-for-sale  is adjusted for  amortization  of premiums and  accretion of
discounts to maturity.  Such amortization is included in investment income along
with interest earned.  Realized gains or losses, and declines in value judged to
be other than  temporary  are also  included in  investment  income.  Management
believes the credit risk associated with these investments is limited due to the
nature of investments.

              Notes to Consolidated Financial Statements--Continued



         For the  year  ended  December  31,  1996,  net  unrealized  losses  of
approximately  $621,000 were charged to shareholders' equity,  leaving a balance
at December 31, 1996 of approximately $171,000 of net unrealized losses. For the
year ended December 31, 1995, net unrealized gains of  approximately  $2,755,000
were charged to shareholders' equity,  leaving a balance at December 31, 1995 of
approximately $450,000 of net unrealized gains.

Property and Equipment

         Property   and   equipment   is  stated  at  cost,   less   accumulated
depreciation.  Depreciation  is provided over the estimated  useful lives of the
respective assets (three to five years) on the straight-line basis.

Notes Receivable from Officers

         In August,  1996,  the Company  extended a loan to one of its executive
officers with an aggregate  principal amount of $1,000,000 to be used to finance
the purchase of his primary  residence.  The loan was secured by a first deed of
trust on the  property,  bears  interest  at 8% per annum and is payable in five
years,  subject to renewal if the  executive  officer  remains  employed  by the
Company.  In June 1995,  the  Company  extended  a loan to one of its  executive
officers with an aggregate  principal amount of $1,365,000 to be used to finance
the purchase and renovation of his primary residence.  The loan was secured by a
first deed of trust on the property and 20,000  shares of SciClone  Common Stock
owned by the executive officer,  bears interest at 7.5% per annum and is payable
in five years,  subject to renewal if the executive  officer remains employed by
the Company.

         In July 1995,  the Company  extended a loan to one of its board members
and former  executive  officers in the principal amount of $95,000 which carries
an interest rate of 7.375%. In December 1995, the Company extended an additional
loan to this  individual in the principal  amount of $600,000,  which carries an
interest  rate of 7.50%.  The loans are due and  payable in December  1997,  are
currently  unsecured,  and in the  process of being  secured by a second deed of
trust on residential property owned by this individual.

         At  December  31,  1996,  the fair value of the notes  receivable  from
officers is $2,710,000.  The fair value was estimated using discounted cash flow
analyses,  using interest rates  currently  being offered for loans with similar
terms of borrowers of similar credit quality.

Foreign Currency Translation

         The  Company  has  determined  the  U.S.  dollar  to be the  functional
currency  for  its  wholly  owned  subsidiaries.   Adjustments   resulting  from
translation are included in results of operations and have not been significant.

Research and Development

         Research and  development  expenditures  are charged to  operations  as
incurred.

              Notes to Consolidated Financial Statements--Continued


Income Taxes

         Income tax expense is based on reported  results of  operations  before
extraordinary  items and income taxes.  Deferred income taxes reflect the impact
of temporary differences between the amount of assets and liabilities recognized
for financial  reporting  purposes and such amounts recognized for tax purposes.
These  deferred  taxes are measured by applying  current tax laws.  Based on the
Company's lack of earnings  history,  deferred tax assets have been fully offset
by a valuation allowance.

 Retirement Benefits

         The Company has a pre-tax savings plan covering  substantially all U.S.
employees,  which qualifies  under Section 401(k) of the Internal  Revenue Code.
Under the plan,  eligible  employees  may  contribute a portion of their pre-tax
salary, subject to certain limitations.  The Company contributes and matches 20%
of the  employee  contributions,  up to 6% of  the  employee's  salary.  Company
contributions,  which  can be  terminated  at  the  Company's  discretion,  were
$25,000,  $24,000,  and $24,000 for the years ended December 31, 1996, 1995, and
1994, respectively. The plan commenced on January 1, 1991.

Net Loss Per Share

         Net loss per share has been computed using the weighted  average number
of common and common equivalent shares outstanding during each period presented.
Common equivalent shares for outstanding  options and warrants were not included
in  the  weighted  average  shares  outstanding  because  the  effect  would  be
antidilutive.

Accounting for Employee Stock-Based Compensation

         In October  1995,  the  Financial  Accounting  Standards  Board  issued
Statement of Financial  Accounting  Standards No. 123 ("SFAS 123"),  "Accounting
for Stock-Based  Compensation."  As permitted by SFAS 123, the Company  accounts
for its stock option and employee  stock  purchase plans under the provisions of
Accounting  Principles Board Opinion 25 ("APB 25") and related  Interpretations.
Accordingly,  the Company does not recognize  compensation expense in accounting
for its stock option and employee  stock purchase plans for awards which have an
exercise price equal to the fair value of the Company's common stock on the date
of the grant.

Reclassifications

         Certain  prior year  amounts have been  reclassified  to conform to the
current year's presentation.

Note 5    - License Agreements

         In October  1996,  the Company  entered  into an  expanded  and amended
license and supply agreement with  Schering-Plough  K.K.  ("SPKK"),  giving SPKK
exclusive  rights to ZADAXIN in Japan.  Under the amended  agreement,  SPKK will
continue  development of thymosin alpha 1 as a monotherapy  for the treatment of
hepatitis B and will initiate  investigation of the combination of its INTRON(R)
A  (interferon  alfa-2b) with ZADAXIN for the treatment of hepatitis C, with the
parties  sharing  certain   development   expenses.   SPKK  will  undertake  the
development,  registration  and marketing of ZADAXIN in Japan.  Contingent  upon
successful  research and development  results,  SciClone will receive  milestone
payments.  To date,  there has been no license  fee  revenue  recognized  by the
Company.

         In April 1996,  the Company  acquired an  exclusive  license for CPX, a
synthetic compound  developed by the National  Institutes of Health ("NIH") as a
potential  treatment for cystic  fibrosis.  NIH will receive  certain  milestone
payments  upon  successful  research  and  development  results in  addition  to
royalties on net sales revenue.

         In  December  1994,  the  Company   acquired  the  rights  to  develop,
manufacture,   and  commercialize  thymosin  alpha  1  in  South  Korea  from  a
pharmaceutical company.

         In August 1994,  SciClone entered into a 15-year license agreement with
Alpha 1  Biomedicals,  Inc.,  ("Alpha 1") for rights to  thymosin  alpha 1. This
agreement grants the Company manufacturing and marketing rights and the right to
conduct  research and  clinical  development  for  existing and new  indications
worldwide  except in Italy,  Spain,  Portugal and South Korea. In addition,  the
agreement  transferred control of Alpha 1's thymosin alpha 1 patent portfolio to
the Company.  The agreement  requires the Company to pay certain royalties based
on net sales revenue of thymosin alpha 1 in the Company's  territories (see Note
7). In connection with this license  agreement,  the Company  incurred a special
research  and  development  charge  of  $3,470,000  consisting  primarily  of  a
write-down of the Company's  equity interest in Alpha 1 to its estimated  market
value and  expenses  associated  with the  transaction.  These  costs  have been
expensed as in-process research and development.

</TABLE>

         Deferred tax assets relating to net operating loss  carryforwards as of
December 31, 1996 include  $3,300,000  associated with stock option activity for
which any  subsequently  recognized  tax benefits  will be credited  directly to
shareholders' equity.

          At December 31, 1996, the Company had net operating loss carryforwards
for U.S. tax purposes totaling approximately $26,000,000, expiring in 2006-2011,
and  approximately  $12,000,000  in  state  net  operating  losses  expiring  in
1997-2001.  The  difference  between  the  current  year's  loss  for  financial
reporting purposes and federal income tax purposes is primarily  attributable to
losses incurred by the Company's foreign subsidiaries.

         Due to the  change in  ownership  provisions  of the Tax  Reform Act of
1986,  utilization  of net  operating  loss  carryforwards  are limited  against
taxable income in future periods.


Note 7  - Commitments and Contingencies

Leases

         The Company  leases its main  office  facility  under a  non-cancelable
lease  agreement  which expires in April 2000. The lease is for a period of five
years and requires the Company to pay insurance and taxes and its pro-rata share
of operating expenses.  The Company also leases various office facilities abroad

              Notes to Consolidated Financial Statements--Continued



under non-cancelable lease agreements, expiring in 1997. Rental expense in 1996,
1995, and 1994 was $397,000, $391,000, and $333,000 respectively. Minimum future
rental  commitments  amount to $448,000 in 1997,  $436,000 in 1998,  $450,000 in
1999, $162,000 in 2000 and $38,000 in 2001.

Royalties

         Under the April 1996 CPX license agreement with the NIH, the Company is
obligated  to pay the NIH a  royalty  based  on a  percentage  of CPX net  sales
revenue. To date, no royalty amounts have been paid or are due to the NIH. Under
the August 1994 thymosin  alpha 1 license  agreement  with Alpha 1 (see Note 5),
the  Company  is  obligated  to pay Alpha 1 certain  royalties  in  addition  to
assuming  certain  Alpha 1 royalties  payable to third  parties.  The  Company's
royalty obligations to Alpha 1 are based on a percentage of thymosin alpha 1 net
sales  revenue and range from 3 to 3.5% or 6 to 7% dependent  upon the territory
in which revenue is recognized and whether or not certain intellectual  property
protection exists in that territory.  Royalties are payable to Alpha 1 for eight
years;  provided,  however  that at  such  time if  Alpha  1 has not  been  paid
aggregate royalties of $35 million, the Company's royalty obligations to Alpha 1
will  continue  to the  earlier  of (i) the  payment  to  Alpha  1 of  royalties
aggregating  $35 million or (ii) September 30, 2009. In 1996,  Alpha 1 agreed to
accept  $500,000  from the  Company  as  prepayment  for $2.5  million in future
royalties  which  may  become  due to  Alpha 1 from  the  Company.  The  prepaid
royalties  will take effect after payment by the Company to Alpha 1 of royalties
totaling $1.75 million.

         In October  1992,  the Company  amended its services  agreement  with a
Japanese trading company.  Upon receipt by SciClone of any revenues in Japan for
thymosin  alpha 1, the  Japanese  trading  company  will  receive a royalty as a
percentage of such revenues for a specified  period of time. To date, no royalty
amounts have been paid or are due the Japanese  trading  company with respect to
this agreement.


Note 8 - Shareholders' Equity

Common Stock

         In January 1994, the Company sold  2,000,000  shares of common stock in
an  underwritten  public  offering  at $23.25 per share.  The  Company  received
approximately $43,600,000 in net proceeds from the offering.

         In conjunction  with its initial public  offering,  the Company granted
its investment  banker  warrants to purchase  300,000 shares of common stock and
300,000  non-redeemable  warrants.  The warrants are exercisable during the four
year period ending March 16, 1997.  The exercise  price of the 300,000 shares of
common  stock is  subject  to certain  adjustments  as  defined in the  purchase
agreement.  At December 31, 1996, the shares of common stock may be purchased at
$6.00 per share, and the  non-redeemable  warrants may be purchased at $0.33 per
warrant.  The  non-redeemable  warrants are exercisable into one share of common
stock at $15.55 per share.  During 1996 and 1995,  no warrants  were  exercised.
During 1994,  135,005  warrants to purchase common stock at $6.00 per share were
exercised.

         At December 31, 1996,  464,995 common shares were reserved for exercise
of the warrants.

Repurchase of Common Stock

         In 1995 and 1994,  the  Company's  Board of  Directors  authorized  the
repurchase of up to 1.5 million and 1.0 million  shares of the Company's  common
stock,  respectively.  For the year ended December 31, 1996, 1995, and 1994, the
Company repurchased 78,000, 346,000 and 1,148,000 shares of its common stock for
an aggregate cost of $659,000,  $1,925,000 and $7,798,000,  respectively.  There
was no impact on the Company's results of operations.

Stock Award Plans

         In August 1991, the Board of Directors and  shareholders of the Company
approved the 1991 Stock Plan (the "1991 Plan") and reserved 1,300,000 shares for
issuance thereunder. In May 1993, the Board of Directors and shareholders of the
Company  approved a 2,150,000  share  increase in the shares  reserved under the
1991 plan.  The 1991 Plan permits the award of incentive or  nonqualified  stock
options and shares of common stock under restricted  stock purchase  agreements.
In January 1992, the Board of Directors and shareholders of the Company approved
the 1992 Stock Plan (the "1992 Plan") and reserved  240,000  shares for issuance
thereunder.  The 1992 Plan permits the award of incentive or nonqualified  stock
options  which must be exercised in cash.  In June 1995,  the Board of Directors
and the shareholders of the Company approved the 1995 Equity Incentive Plan (the
"1995 Plan") and reserved  1,250,000  shares for issuance  thereunder.  The 1995
Plan permits the award of incentive or nonqualified  stock options and shares of
common stock under restricted stock awards.

         Under the 1991,  1992 and 1995  Plans,  options  are  exercisable  upon
conditions  determined  by the Board of Directors  and expire ten years from the
date of grant. Options are generally granted at fair market value on the date of
grant and vest over time, generally four years.

         In June  1995,  the  Board of  Directors  and the  shareholders  of the
Company  approved the Nonemployee  Director Stock Option Plan (the  "Nonemployee
Director  Plan") and  reserved  250,000  shares  for  issuance  thereunder.  The
Nonemployee  Director Plan  automatically  grants  nonqualified stock options to
nonemployee  directors upon their appointment or first election to the Company's
Board of Directors  ("Initial  Grant") and annually upon their reelection to the
Board of Directors at the  Company's  Annual  Meeting of  Shareholders  ("Annual
Grant").  The options  are  granted at fair  market  value on the date of grant.
Initial  Grants vest annually  over a period of three years.  Annual Grants vest
monthly over a period of one year.

         In July 1996,  the Board of Directors and  shareholders  of the Company
approved the 1996 Employee Stock Purchase Plan (the "ESPP") and reserved 500,000
shares  for  issuance  thereunder.  All  full-time  employees  are  eligible  to
participate  in the ESPP.  Under the terms of the ESPP,  employees can choose to
have up to 15% of their salary withheld to purchase the Company's  common stock.
The purchase  price of the stock is the lower of 85% of the fair market value as
of the first trading day of each quarterly  participation  period,  or as of the
last trading day of each  quarterly  participation  period.  Under the ESPP, the
Company sold 5,675 shares to employees in 1996.

              Notes to Consolidated Financial Statements--Continued



         As  permitted  by SFAS 123,  the  Company  applies  APB 25 and  related
Interpretations  in accounting for its stock award plans and  accordingly,  does
not recognize compensation expense for awards which have an exercise price equal
to the fair value of the Company's common stock on the date of the grant.

         Pro  forma  information  regarding  net loss and net loss per  share is
required by SFAS 123 and has been determined as if the Company had accounted for
its stock awards under the fair value method of that  Statement.  The fair value
for the options was estimated at the date of grant using a Black-Scholes  option
pricing model with the following weighted-average assumptions for 1996 and 1995:
risk-free  interest rates of 5.14% and 6.81%,  respectively;  dividend yields of
0%;  volatility  factors of the expected  market price of the Company's stock of
 .84; and a weighted  average expected life of the option of 4.37 years. The fair
value  for  the  employee  stock   purchases  was  also   estimated   using  the
Black-Scholes model with the following  assumptions for 1996: risk-free interest
rate of 5.3%; dividend yield of 0%; expected volatility of .84 and expected life
of .25 years.

         The  Black-Scholes  option  valuation  model was  developed  for use in
estimating the fair value of traded  options which have no vesting  restrictions
and are fully  transferable.  In addition,  option  valuation models require the
input of highly  subjective  assumptions  including  the  expected  stock  price
volatility.  Because the Company's  employee  stock awards have  characteristics
significantly  different from those of traded  options,  and because  changes in
subjective input assumptions can materially  affect the fair value estimate,  in
the Company's opinion, the existing models do not necessarily provide a reliable
single  measure  of the fair  value of its  employee  stock  options  and  stock
purchases.

         The  Company  recorded  deferred  compensation  of  approximately  $2.4
million related to 1992 stock option grants. The deferred  compensation is being
amortized over the vesting period,  which ranges from two to five years. For the
years ended December 31, 1996, 1995, and 1994, approximately $205,000, $555,000,
and $487,000 of deferred compensation related to stock option grants was charged
to compensation expense, respectively.

         Had compensation expense for the Company's option and employee purchase
plans  been  determined  based on the fair value at the grant date for awards in
1996 and 1995 consistent with the provisions of SFAS 123, the Company's net loss
and net loss per  share  would  have  been  adjusted  to the pro  forma  amounts
indicated below:

                                           1996                   1995
                                           ------                 ----

Net loss - as reported                $(14,746,000)          $(14,775,000)
                                      -------------          -------------

Net loss - pro forma                  $(15,821,000)          $(14,643,000)
                                      =============          =============

Net loss per share - as reported            $(0.85)                $(0.88)
                                            =======                =======

Net loss per share - pro forma              $(0.91)                $(0.87)
                                            =======                =======

         The  effects of  applying  SFAS 123 for pro forma  disclosures  are not
likely to be  representative  of the  effects  on  reported  net loss for future
years.  Pro  forma  net loss for the  year  ended  December  31,  1996

                       ADVERSE EVENT REPORTING PROCEDURES

         SciClone  and SPKK  hereby  agree that the  following  conditions  will
govern  disclosures  of each  party to the other with  respect to adverse  event
reporting relating to the Licensed Products:

I.         DEFINITIONS

           A.     An "Adverse Event" ("AE") is defined as:

                  (i) any expected or  unexpected  experience  which is adverse,
           including  what are  commonly  described  as adverse  or  undesirable
           experiences,  adverse events,  adverse  reactions,  side effects,  or
           death  due to any  cause  associated  with  the  use of any  Licensed
           Product,  or observed  in  conjunction  with the use of any  Licensed
           Product,  whether  or  not  considered  related  to the  use of  such
           Licensed Product:

                      o    occurring  in the  course of the use of any  Licensed
                           Product,

                      o    associated  with,  or observed in  conjunction  with,
                           Licensed  Product  overdose,  whether  accidental  or
                           intentional,

                      o    associated  with,  or observed in  conjunction  with,
                           Licensed Product abuse, or

                      o    associated  with,  or observed in  conjunction  with,
                           Licensed Product withdrawal.

                  (ii) Any significant  failure of expected  pharmacological  or
            biologic therapeutic action (with the exception of clinical trials).

           B.     "Serious AE" and "Non-Serious AE" are defined as follows:

                  (i) A "Serious AE" is one that is  life-threatening  or fatal,
           permanently   disabling,   requires  in-patient   hospitalization  or
           prolonged  hospitalization,  or is a  congenital  anomaly,  cancer or
           overdose. In addition,  end-organ toxicity,  including hematological,
           renal,  hepatic,  and central  nervous  system AEs may be  considered
           Serious.  In laboratory  tests in animals,  a serious AE includes any
           experience suggesting significant risk for human subjects.

                  (ii) A  "Non-serious  AE" is any AE  which  does  not meet the
            criteria for a serious AE.

           C. The following terms used in paragraphs (i) and (ii) above have the
meanings set forth below:

<PAGE>

                  (i)  "life-threatening"  is  defined as the  patient  being at
           immediate risk of death from the AE as it occurs;

                  (ii)   "end-organ   toxicity"   is  defined  as  a   medically
           significant  event or laboratory  value change in which a patient may
           not necessarily be hospitalized or disabled,  but which is clinically
           significant  enough  to  warrant  monitoring  (e.g.  seizures,  blood
           dyscrasias, etc.);

                  (iii) "expected  experience" is defined as an experience which
           is listed in SciClone's  Investigator's Brochure for clinical trials,
           included  in local  labelling  (e.g.,  Summary  of  Licensed  Product
           Characteristics)  for the Licensed Product,  or, in countries with no
           local labelling,  listed in SciClone's Corporate Standard Prescribing
           Document;

                  (iv) "unexpected  experience" is defined as an experience that
           does not  meet  the  criteria  for an  expected  AE or an AE which is
           listed  but  differs   from  that  event  in  terms  of  severity  or
           specificity; and

                  (v)  "associated  with  the use of any  Licensed  Product,  or
           observed in conjunction  with the use of any Licensed  Product" means
           that a  reasonable  possibility  exists that the AE was caused by the
           Licensed Product.

II.        REPORTING

           A. All initial  reports and follow-ups  (oral or written) for any and
all Serious AEs as defined  above  (other than with  respect to animal  studies)
which become known to one party (other than from  disclosure  by or on behalf of
the other party) must be communicated by telephone or telefax to the other party
within  three (3) working  days (or,  in the case of a death,  one (1) day) from
receipt of the information.  Written confirmation of a Serious AE should be sent
to the other party as soon as it becomes available,  but in any event within one
(1) day of the initial report of the AE by the reporting party.

           SciClone may conduct its own investigation of reported Serious AEs.

           All  initial  reports,  if any,  and  follow-ups,  if any  (oral  and
written),  for all  Non-serious  AEs as defined above which become known to SPKK
(other than from disclosure by or on behalf of SciClone) must be communicated in
writing to SciClone on a monthly basis.

           SciClone may conduct its own investigation of any reported Serious AE
and Non-serious AE.

           B.  Other  reporting  requirements  with  respect  to AEs shall be as
follows:

                  (i) For AEs  occurring  in  animal  studies  which  suggest  a
           potential  significant  risk for  humans,  a written  report  must be
           forwarded to SciClone as soon as the results are received by SPKK.



<PAGE>

                  (ii)  Within  thirty  (30) days of receipt  of a request  from
           SciClone,  but not more  often  than  twice a year,  SPKK  will  give
           SciClone a  print-out  or  computer  disk of all AEs  reported  to it
           within the last year.

                  (iii) If SciClone wishes access to AE reports of SPKK relating
           to  Licensed   Products,   SPKK  shall  make  available  its  records
           (including  computer  disks) for  viewing  and  copying  by  SciClone
           promptly upon request.

           C. Disclosure of information concerning AEs by SPKK to SciClone shall
continue as long as the SPKK continues to clinically test or market the Licensed
Products.

III.       IMPLEMENTATION

           A. SciClone and the SPKK also agree to meet in a timely  fashion from
time to time as may be  reasonably  required  to  implement  the  adverse  event
reporting and consultation procedures described in this Article.

                                    EXHIBIT J

                                   ARBITRATION


         The parties  recognize  that a bona fide dispute as to certain  matters
may from time to time arise  during the term of the  Agreement.  In the event of
the  occurrence of any dispute,  controversy or claim arising out of or relating
to the validity,  construction,  enforceability  or performance of the Agreement
including disputes relating to an alleged breach or termination of the Agreement
it shall be settled by binding  Alternative  Dispute  Resolution  ("ADR") in the
manner set forth below;  provided,  however,  that the neutral referred to below
shall give  effect to the  provisions  of the  Agreement  and shall not  adjust,
modify or change the effects of termination as set forth in the Agreement.

         (a) If a party intends to begin an ADR to resolve a dispute, such party
shall provide written notice (the "ADR Request") by certified or registered mail
or properly  documented  overnight  delivery to the other party  informing  such
other party of such  intention  and the issues to be resolved.  The notice shall
explain the nature of the  complaint  and refer to the relevant  sections of the
Agreement upon which the complaint is based.  The  complaining  party shall also
set forth a proposed  solution to the problem,  including a suggested time frame
within which the parties must act.

         (b) The non-complaining party must respond in writing within forty-five
(45) days of receiving notice with an explanation,  including  references to the
relevant provisions of the Agreement and a response to the proposed solution and
suggested time frame for action.  The  non-complaining  party may add additional
issues to be resolved.

         (c)  Within  fifteen  (15) days of  receipt  of the  response  from the
non-complaining  party, the parties shall meet and discuss options for resolving
the  dispute.  The  complaining  party  must  initiate  the  scheduling  of this
resolution  meeting.  Each party shall make available  appropriate  personnel to
meet and  confer  with the  other  party  within  the  fifteen  (15) day  period
following the complaining party's receipt of the response by the non-complaining
party.

         (d) Any and all disputes that cannot be resolved pursuant to Paragraphs
(a), (b) and (c) shall be submitted to a neutral who shall be selected by mutual
agreement  of the  parties.  If the  parties are unable to agree upon a neutral,
then the neutral  shall be selected in  accordance  with the  procedures  of the
American Arbitration  Association.  The neutral shall be an individual who shall
preside over and resolve any disputes between the parties.  The neutral selected
shall be a former  judge of a state or federal  court and shall not be a current
or former employee, director or shareholder of, or otherwise have any current or
previous relationship with, either party or its respective  affiliates.  The ADR
shall be conducted  in  accordance  with the rules of the  American  Arbitration
Association then in effect,  subject to the time periods and other provisions of
this Exhibit or as otherwise set forth in the Agreement.

         (e)  Consistent  with  the  time  schedule   established   pursuant  to
Paragraphs  (i) and (g) 


<PAGE>

the neutral shall hold a hearing to resolve each of the issues identified by the
parties and shall render the award as  expeditiously as possible but in no event
more than thirty (30) days after the close of hearings.  In making the award the
neutral shall rule on each  disputed  issue and shall be based on in whole or in
part the proposed ruling of one of the parties on each disputed issue.

         (f) During the meeting  referred to in Paragraph (c), the parties shall
negotiate  in good  faith the scope  and  schedule  of  discovery,  relating  to
depositions,  document  production  and other  discovery  devices,  taking  into
account the nature of the dispute  submitted for resolution.  If the parties are
unable to reach agreement as to the scope and schedule of discovery, the neutral
may order such discovery as he deems necessary. To the extent practicable taking
into account the nature of the dispute submitted for resolution,  such discovery
shall be completed  within sixty (60) days from the date of the selection of the
neutral.  At the hearing,  which shall  commence  within  twenty (20) days after
completion of discovery  unless the neutral  otherwise  orders,  the parties may
present   testimony   (either   live   witness   or   deposition),   subject  to
cross-examination,  and documentary  evidence.  To the extent practicable taking
into  account  the  nature  of the  dispute  submitted  for  resolution  and the
availability of the neutral, the hearing shall be conducted over a period not to
exceed  thirty  (30)  consecutive  business  days,  with each party  entitled to
approximately half of the allotted time unless otherwise ordered by the neutral.
In the event that  SciClone  files the ADR  Request  pursuant to  Paragraph  (a)
hereof,  then the hearing shall be conducted in Newark, New Jersey. In the event
that SPKK files the ADR Request  pursuant  to  Paragraph  (a)  hereof,  then the
hearing shall be conducted in San Francisco,  California.  Each party shall have
sole discretion with regard to the  admissibility  of any evidence and all other
matters relating to the conduct of the hearing.  The neutral shall, in rendering
its  decision,  apply the  substantive  law of  California.  The decision of the
neutral  shall be final and not  appealable,  except in the case of fraud or bad
faith  on the  part  of the  neutral  or any  party  to the  ADR  proceeding  in
connection with the conduct of such proceedings.

         (g) At least  twenty (20)  business  days prior to the date set for the
hearing,  each party shall  submit to each other party and the neutral a list of
all  documents  on which  such  party  intends  to rely in any  oral or  written
presentation  to the neutral  and a list of all  witnesses,  if any,  such party
intends to call at such hearing and a brief summary of each witness'  testimony.
At least five (5) business days prior to the hearing,  each party must submit to
the  neutral  and serve on each  other  party a  proposed  findings  of fact and
conclusions  of law on  each  issue  to be  resolved.  Following  the  close  of
hearings,  the parties shall each submit such post-hearing briefs to the neutral
addressing  the  evidence  and  issues  to be  resolved  as may be  required  or
permitted by the neutral.

         (h) Except as otherwise set forth herein,  the neutral shall  determine
the  proportion  in which the  parties  shall pay the costs and fees of the ADR,
except that each party shall pay its own costs (including,  without  limitation,
reasonable  attorneys fees) and expenses in connection with such ADR;  provided,
however,  that if the  neutral  determines  that the  action  of any  party  was
arbitrary,  frivolous  or in bad  faith,  the  neutral  may award such costs and
expenses to the prevailing party.

         (i) The ADR proceeding shall be confidential and, except as required by
law,  neither


<PAGE>

party shall make (or instruct the neutral to make) any public  announcement with
respect to the  proceedings or decision of the neutral without the prior written
consent of the other party.  The existence of any dispute  submitted by ADR, and
the award of the  neutral,  shall be kept in  confidence  by the parties and the
neutral,  except as required in connection with the enforcement of such award or
as otherwise required by applicable law.

         (j) For the  purposes  of these  arbitration  provisions,  the  parties
acknowledge  their diversity and agree to accept the jurisdiction of the Federal
District Court in Newark,  New Jersey or San Francisco,  California (as selected
by the party  seeking to enforce) for the purposes of enforcing  awards  entered
pursuant  to these  arbitration  provisions  and for  enforcing  the  agreements
reflected in this Paragraph (j).

         (k) Nothing  contained  herein shall be construed to permit the neutral
or any court or any other  forum to award  punitive,  exemplary  or any  similar
damages.  By  entering  into  the  Agreement  and  exercising  their  rights  to
arbitrate, the parties expressly waive any claim for punitive,  exemplary or any
similar  damages.   The  only  damages  recoverable  under  this  Agreement  are
compensatory damages.

         (l) The  procedures  specified  herein shall be the sole and  exclusive
procedures  for the  resolution  of  disputes  between  the  parties  which  are
expressly  identified  for  resolution  in  accordance  with  these  arbitration
provisions.

amended and restated pursuant to that certain License Agreement between SciClone
and Alpha dated as of August 19, 1994 (collectively, the "Alpha Agreement"); and

         WHEREAS,  SciClone  owns or has  rights to certain  patents  and patent
applications relating to methods of treatment using TA 1, processes of making TA
1 and TA 1 composition of matter; and

         WHEREAS,  SciClone's  business strategy is to sublicense certain of the
rights it possesses  with respect to TA 1 to third parties for the  development,
distribution and sale of TA 1 within SciClone's  licensed  territory,  including
Japan; and

         WHEREAS, SPKK possesses significant scientific,  business and marketing
expertise  and  capabilities  with  respect  to the  research,  development  and

development  and  marketing of products  incorporating  TA 1 in Japan;  and this
Agreement supersedes and replaces said 1993 agreement in its entirety.

         NOW,  THEREFORE,  in  consideration  of the foregoing  premises and the
covenants and obligations set forth in this Agreement,  the parties hereby agree
as follows:

on SciClone under Article 3 of this  Agreement for  completing  the  Development
Program in Japan.

         2.3.    Sublicensing.

2.1.5 to the extent  necessary to allow  distributors,  wholesalers  and similar
entities  to market  and sell  Licensed  Products  and to allow end users to use
Licensed Products.

                  2.3.3     Additional Indications.  Pursuant to the Development
Program  described  in  Exhibit  D  hereto,   SPKK  and  SciClone  are  pursuing
development  efforts for CHB and CHC  indications.  While SPKK is still pursuing
development and/or  commercialization of either CHB or CHC, if SciClone presents
to  SPKK  all  data  then  available  to  SciClone  as to the  use of the  Alpha
Technology  and/or the SciClone  Technology to reasonably  support an additional
indication within the Field in the SPKK Territory, then SPKK shall decide within
one hundred  twenty (120) days if SPKK wants to add to the  Development  Program
the development work for said additional indication;  and if SPKK decides not to
so add said  additional  indication,  then SPKK and SciClone  shall consider the
suitability and desirability of a sublicense arrangement for the development and
commercialization  of the Alpha  Technology  and/or the SciClone  Technology for
said indication in the SPKK Territory, taking into account the business needs of
each party and to the extent  practicable fully protecting SPKK's market for all
Licensed  Products,  and SciClone shall not grant any such sublicense rights for
said additional  indications without SPKK's prior written consent, which consent
may be withheld in SPKK's sole discretion.

         2.4.    Transfer of Technology

         Following  the Effective  Date and through the term of this  Agreement,
SciClone shall make available to SPKK all Alpha Technical Information,  SciClone
Technical  Information,  Alpha  Improvements,  Alpha Sublicensee  Technology and
SciClone Sublicensee Technology in SciClone's  possession,  subject to the terms
of this Agreement.

coordinate the  relationship of SciClone and SPKK with regard to the development
work to be performed hereunder by SPKK and SciClone (the "Development  Program",
set forth in Exhibit D), SPKK and SciClone shall each appoint one (1) authorized
representative  (hereafter  "Development  Coordinators").  Except  as  otherwise
agreed by the  parties in writing,  or as set forth in Section  7.1 hereof,  all
communications  between  the  parties  shall  be made  through  the  Development
Coordinators.  The Development  Coordinators shall determine mechanisms required
for the exchange of technical,  business and regulatory information with respect
to the Development  Program, to the extent not fully set forth herein. From time
to time as appropriate,  the Development Coordinators may also determine and add
to the  Development  Program  (Exhibit  D) by mutual  agreement  in writing  the
further  implementing  details,  projects  and tasks  necessary  to complete the
development and to obtain the required regulatory  approvals for sale and use of
the Licensed Products in Japan. If the Development  Coordinators deadlock for at
least sixty (60) days on reaching a decision  as to such  implementing  details,
projects  or tasks,  then the subject of the  deadlock  shall be referred to the
Chief Executive  Officers of the parties (or their  designees) for an additional
sixty (60) days of 


                                       4

negotiations, and if the deadlock is still not then resolved, the deadlock shall
be resolved by binding  arbitration in accordance  with the provisions set forth
in Exhibit J hereto.

                  3.1.2     Meetings   of    Coordinators.    The    Development
Coordinators  or such other  representatives  of the parties as are agreed shall
meet in person (or by telephone if mutually agreed) as needed,  but no less than
once a month for one year  after the  Signing  Date,  and once  every  three (3)
months  thereafter,  unless  mutually  agreed  otherwise.  Such  meetings  shall
alternate  between  Japan  and  California  except  as  otherwise  agreed by the
Development Coordinators. At such meetings, among other things, the parties will
review the  objectives  (including  the  development  of Licensed  Products  for
indications  other  than CHC and CHB if  mutually  approved  in  writing by both
parties), review funding requirements, protocols or procedures of or used in the
Development  Program,   will  discuss  any  additional   objectives  or  funding
requirements  necessary for the  implementation  of the Development  Program and
commercialization  of Licensed  Products,  and determine  the  occurrence of the
milestone  events  described  in Sections  5.1 and 5.2.  SPKK (and to the extent
applicable,  SciClone)  shall  present  an  evaluation  of  the  status  of  the
Development Program at such meetings.  Such meetings shall be in English, and at
such times and places  (alternating  between Japan and California) as are agreed
to by the parties and shall be conducted in person (or by  telephone,  facsimile
or in any other manner as the parties  shall agree).  At such meeting,  SPKK and
SciClone shall each give their evaluation as to the progress of the implementing
work for the  Development  Program,  and SPKK and SciClone shall respond to each
other's questions concerning the progress of the Development Program.

                  3.1.3     Shared  Reports.   Subject  to  the  confidentiality
provisions  of Article 10, the parties  shall  freely  share copies of technical
reports and other written documentation,  in Japanese, with English summaries at
SPKK's expense,  and make such oral  presentations  as may be necessary to fully
evaluate the progress of the Development Program.

                  3.1.4     Travel  Costs.  The costs for travel and  lodging to
attend all meetings,  including pursuant to Sections 3.1 and 7.1, shall be borne
by the traveling party.

         3.2.  Visits to  Facilities  Representatives  of  SciClone  may,  upon
reasonable request and notice and at times and intervals  reasonably  acceptable
to SPKK, (i) visit SPKK's or its sublicensee's  facilities where the Development
Program is being  conducted,  and (ii) in  conjunction  with SPKK's  Development
Coordinator,   consult   informally   with  personnel  of  SPKK  conducting  the
Development Program during such visits, by telephone,  facsimile transmission or
such other manner as the parties shall agree.

         3.3.    Development Obligations of SPKK.

                  3.3.3     Chief  Investigators;  Study  Centers. For any multi
center  Phase II and Phase III  clinical  trials which may be agreed upon by the
parties hereto, one or more chief investigators shall be selected [*REDACTED] as
well as the identity of such centers.

                  3.3.4     Intentionally Omitted.

                  3.3.5     Development Reports;  Notices. SPKK will prepare and
deliver to SciClone,  in English,  beginning  January 30, 1997, and on or before
January 30 of each year thereafter,  an annual  development plan for TA 1 in CHC
and CHB and such other indications as are agreed upon by the parties, as well as
quarterly  progress  reports  within  thirty  (30)  days  after  the end of each
calendar  quarter.  SPKK shall notify SciClone upon the conclusion of each phase
of clinical trials with respect to a given indication.

                  3.3.6     Trademarks.  Except as otherwise  agreed in writing,
SPKK agrees and acknowledges that SPKK and its permitted  sublicensees shall use
only the Marks and no other  trademarks in connection  with the  development and
testing of Licensed Products.

         3.4.    Development Obligations of SciClone.

                  3.4.1     Supply  of TA 1 For  Development Purposes.  SciClone

parties  of  record  for the  Program  Data,  the  Regulatory  Filings,  and any
applicable  governmental  approvals or licenses for the manufacture,  use and/or
sale of Licensed  Products in Japan. To the extent that applicable  Japanese law
or  regulation  permits such co developer  status or co parties of record status
only through some special arrangement or mechanism (such as SciClone using an in
country caretaker or CRO agent, or SciClone or its designee  performing at least
10% of the work, or SciClone assigning or sublicensing  certain obligations to a
designee,  or some other  arrangement),  then  SciClone  may  implement  such an
arrangement  or mechanism,  notwithstanding  anything to the contrary  contained
elsewhere  in this  Agreement.  The  intention  and effect of said co  developer
status or co parties of record status is to enable SciClone (or its designee) to
be in a position,  immediately upon any termination of SPKK's exclusive  license
rights  under this  Agreement,  to market and sell  Licensed  Products  in Japan
without any delay.

                    PROGRAM DATA; IMPROVEMENTS AND INVENTIONS

         4.1.  Program Data Rights and Licenses All right, title and interest in
and to the Program Data shall reside solely with SPKK; provided,  however,  that
SPKK hereby grants to SciClone:

                      (a) an exclusive, even as to SPKK, royalty free, perpetual
license, with the right to sublicense to the SciClone Sublicensees,  to use such
Program Data within the SciClone  Territory  solely for SciClone's  development,
marketing  and  sale  of TA 1  products  in the  SciClone  Territory,  including
marketing  activities  and  governmental  filings for  regulatory  approvals and
patent filing, prosecution and maintenance;

                      (b) a perpetual,  exclusive  (even as to SPKK)  license to
use such  Program  Data outside the SPKK  Territory  and the SciClone  Territory
solely for the development,  marketing and sale of TA 1 products, with the right
to  sublicense  to Alpha,  the Alpha  Sublicensees  and  Roche,  subject  to the
negotiation in good faith of the consideration  for such sublicense  (whether in
the form of royalties or license  fees) by SciClone and SPKK, at the time of any
such sublicense grant,  based upon the commercial value of such Program Data and
SPKK's overall licensing policies; and

                      (c) with respect to any license  granted to SciClone under
Sections  4.1(a) or (b) above which relates to or is derived from Intron A, said
license shall be only to develop  (including the governmental  filings set forth
in Paragraph 4.1(a) above), market and sell TA-1, and said license is subject to
the consent of SPKK,  which  consent can be withheld only if SPKK (or any of its
Affiliates)  reasonably  determines  that such license  would have a significant
negative impact on the sales of Intron A either in Japan or worldwide.



                                       8

         SPKK  will make  available  to  SciClone  any and all  Program  Data it
generates  or  acquires,   in  its  original  form,  together  with  an  English
translation  paid for  equally by SPKK and  SciClone.  The  foregoing  grants to
SciClone  shall not  inhibit or  otherwise  impair  rights of SPKK or any of its
Affiliates to use the program data to develop,  market, sell and use INTRON-A in
any country in the world.

         4.2.    Improvements.

                  4.2.1     Development   of   Improvements.   Subject   to  and
consistent with the other terms of this Agreement,  SPKK and SciClone each agree
to  cooperate  with  respect  to  Improvements,   including   expansion  of  the
indications for TA l, improving TA l's efficacy and enhancing TA l's proprietary
position.

                  4.2.2     Transfer of  Information.  SPKK and  SciClone  shall
each  cooperate to fully  disclose to the other (but only where such  disclosure
would not adversely affect attainment of patent  protection),  within sixty (60)
days after the Signing Date and on an ongoing basis,  any and all  Improvements,
including,  without limitation,  all data, materials,  copies of notebooks, know
how, related patent applications and the like related thereto.

        4.3.  Inventions.  Each party  acknowledges  and agrees that any and all
Inventions arising from any Improvements that are made or discovered pursuant to
this  Agreement  solely by its  employees  or agents shall be owned solely by it
(the "SPKK Inventions" or the "SciClone Inventions" as the case may be) and that
any and all  Inventions  made jointly by employees or agents of each pursuant to
this Agreement shall be jointly owned ("Joint Inventions"), all as determined in
accordance with U.S. laws of inventorship;  provided, however, that in the event
of any conflict  between U.S. law and the applicable  laws of Japan which arises
in the course of the prosecution in Japan of any patent  application on any SPKK
Invention  or Joint  Invention,  the  applicable  laws of Japan  shall  control.
Notwithstanding  the foregoing,  with respect to Japan,  any Inventions  arising
from Improvements made or discovered  pursuant to this Agreement  relating to or
derived  from  Intron  A or  treatment,  alone  or  in  combination  with  other
pharmaceutical  compositions,  with  Intron A,  shall be  solely  owned by SPKK,
provided,  however, said ownership by SPKK is not necessarily  indicative of, or
is to  be  construed  as  an  admission  as  to,  inventorship  or  priority  of
inventorship of any invention,  including without  limitation,  existing patents
and pending patent applications worldwide to which SciClone has rights.

         4.4.   License to SPKK Inventions and Joint Inventions.

                      (a) Subject to the terms and conditions of this Agreement,
including,  in  particular,  Sections  4.4(b) and 6.3.9,  SPKK hereby  grants to
SciClone:

                            (i) an  exclusive,  even as to SPKK,  royalty  free,
perpetual  license  to  practice  and  use the  SPKK  Inventions  and the  Joint
Inventions,  within the SciClone Territory,  with the right to sublicense to the
SciClone  Sublicensees which use shall include,  without  limitation,  marketing
activities and governmental  filings for regulatory approvals and patent filing,
prosecution and  maintenance,  for SciClone's  development and marketing of TA 1
products in the SciClone Territory; and


                                       9
<PAGE>


                            (ii) a perpetual,  non exclusive license to practice
and use the SPKK Inventions and the Joint Inventions, outside the SPKK Territory
and the SciClone  Territory,  with the right to sublicense  to Alpha,  the Alpha
Sublicensees and Roche.

         The foregoing  grants to SciClone shall not inhibit or otherwise impair
the rights of SPKK or any of its  Affiliates to use SPKK  inventions  and/or the
Joint Inventions to develop, market, sell and use INTRON-A in any country in the
world. As to any sublicenses  granted after the Signing Date under subparagraphs
(i) or (ii) above,  SciClone shall diligently seek to obtain fair and reasonable
compensation for the granting of such  sublicenses,  and shall share with SPKK a
fair and reasonable portion of any compensation which SciClone receives from any
such sublicensee,  [*REDACTED] and a reasonable portion of any other non-royalty
consideration  received by SciClone  from such  sublicensee.  SciClone  and SPKK
shall  negotiate  in good  faith to  determine  the  reasonable  portion of said
consideration to be paid to SPKK, based upon, and taking into full account,  all
relevant legal and factual matters,  considerations,  and relative contributions
related  to the  sublicense  transaction.  If the  parties  are  unable to reach
agreement as to the proportion to be paid by SciClone to SPKK, then said portion
shall be determined  pursuant to the dispute resolution  provisions set forth in
Article 15 of this Agreement.

         The parties  acknowledge  that the rights  granted in clause (ii) above
have been extensively negotiated, reflect SPKK's expressed concern that the SPKK
Inventions and the Joint  Inventions not flow into the hands of its  competitors
or  potential   competitors   without   compensation,   and  reflect  SciClone's
commercially  reasonable  efforts  to  obtain  for  Alpha,  Roche  and the Alpha
Sublicensees  rights  to  the  SPKK  Inventions  and  the  Joint  Inventions  in
accordance with the Alpha Agreement.

                      (b) With respect to any license  granted to SciClone under
Section 4.4 (a) above which relates to or is derived from Intron A, said license
shall be only to develop,  market and sell TA-1,  and said license is subject to
the consent of SPKK,  which  consent can be withheld only if SPKK (or any of its
Affiliates)  reasonably  determines  that such license  would have a significant
negative impact on the sales of Intron A either in Japan or worldwide.

                                LICENSE PAYMENTS

         5.1. Milestone Payment for CHB. Except as provided in Section 5.3, SPKK
shall make to SciClone  the  following  non  refundable  CHB  milestone  payment
[*REDACTED].

         5.2. Milestone Payment for CHC. Except as provided in section 5.3, SPKK
shall make to SciClone  the  following  non  refundable  CHC  milestone  payment
[*REDACTED].

         5.3.  Waiver  of  Certain  Milestone  Payments.  In the  event  SPKK is
successful  in  obtaining  an  extension  to  Japanese  Patent No.  [*REDACTED],
contained  in the Alpha  Patents  (whether  by actions  relating  solely to such
patent or by more general  lobbying  efforts with respect

to changes in Japanese patent law),  [*REDACTED].  SPKK  acknowledges and agrees
that in the event such an extension is obtained  primarily for reasons unrelated
to actions on the part of SPKK, the waiver set forth above shall not apply.

                                    ARTICLE 6

          SUPPLY OF TA-1 MATERIAL AND MANUFACTURE OF LICENSED PRODUCTS

         6.1.  Manufacture  and Supply of TA 1 Material.  SciClone  warrants and
represents  that as of the Signing  Date it has the right under the terms of the
Alpha  Agreement  (as  amended) to make,  manufacture,  synthesize  or otherwise
produce or have made,  manufactured,  synthesized  or  otherwise  produced  TA 1
Material.

         6.2.  Clinical Supply. SciClone shall use diligent  efforts to cause to
be supplied to SPKK,  [*REDACTED]  such  amounts of TA-1  Material  necessary to
conduct preclinical and clinical studies pursuant to the Development Program and
to obtain regulatory approval for Licensed Products.  SPKK will provide SciClone
with  rolling six (6) month  forecasts  of its  clinical  requirements  for TA-1
Material  on a  quarterly  basis,  beginning  within  thirty (30) days after the
Signing Date.

         6.3. Commercial Supply.

                  6.3.1     Commercial Supply Agreement. SciClone agrees that it
will use diligent efforts for it or its designated  Affiliate to manufacture and
sell, and SPKK will purchase from SciClone or SciClone's  designated  Affiliate,
all of SPKK's reasonable commercial  requirements of (i) TA 1 Material; and (ii)
in the event  that SPKK  notifies  SciClone  that it is  unable to  perform  all
aspects of the Final Processing of TA 1 Material to produce  Licensed  Products,
such other unfinished  materials prepared from TA 1 Material (e.g.,  lyophilized
TA 1 Material) as to enable SPKK to produce Licensed Products, regardless of the
number of filed NDA(s) and marketing  methods used for Licensed  Products.  Such
supply shall be pursuant to a commercial  supply  agreement to be  negotiated in
good faith between the parties,  which agreement adequately reflects both SPKK's
needs for TA 1 Material and SciClone's  available resources and commitments (the
"Commercial Supply Agreement"). Negotiation for said Commercial Supply Agreement
shall be commenced  within thirty (30) days after, and shall be completed within
twelve (12) months after, the filing of the first NDA with respect to a Licensed
Product.   Such  Commercial   Supply  Agreement  will  incorporate  those  terms
substantially  as set forth  below  with  respect to  commercial  supply of TA 1
Material and other  unfinished  material to be supplied by SciClone,  if any, as
well as certain  additional  terms  related to  ordering  and  delivery  of TA 1
Material  and other  unfinished  material to be supplied  by  SciClone,  if any,
forecasts,  compliance  with  specifications,  and inspection,  acceptance,  and
return  of TA 1  Material  and  other  unfinished  material  to be  supplied  by
SciClone,  if any, as outlined in Exhibit H, and other  provisions  customary to
this kind of contract in the pharmaceutical industry.

                  6.3.2     Cutbacks in Supply.  In the event SciClone is unable
to supply, or cause to be supplied, to SPKK and the SciClone Sublicensees all of
each of their  reasonable  commercial  requirements  of TA 1 Material,  SciClone
shall decrease the amount to be supplied to each SciClone  Sublicensee  and SPKK
proportionately according to the prior sales of each of them.

                  6.3.3     SPKK Contingent Manufacturing Rights. Subject to the
terms of the  Alpha  Agreement,  and to the  terms of this  Agreement,  SciClone
hereby  grants to SPKK a sublicense  of its rights under the Alpha  Agreement to
make, manufacture,  synthesize or otherwise produce or have made,  manufactured,
synthesized  or  otherwise  produced,  SPKK's  commercial  requirements  of TA 1
Material, which sublicense shall become effective if and only if:

                      (i) either:

                      (a) SciClone  determines that it is not reasonably able to
supply, or arrange to supply, all of SPKK's reasonable  commercial  requirements
of TA 1 Material; or

                      (b)  SciClone  is  unable  to  supply  SPKK's   reasonable
commercial  requirements of TA 1 Material in such amounts and for such period of
time as is agreed upon by the parties at the time of negotiation  of, and as set
forth in, the Commercial Supply Agreement; or

                      (c)  SciClone  and  SPKK  have   reasonably   agreed  such
sublicense shall become effective; and

                              (i) the  parties  have  agreed,  pursuant  to good
faith negotiations, to a mechanism (including the royalty payable to SciClone as
set forth in Section 6.3.6 hereof) for minimizing any adverse  financial effects
to either party that may result from the cessation of supply of TA 1 Material by
SciClone and the conferral of such  contingent  manufacturing  rights upon SPKK;
and

                              (ii)  SciClone  shall be permitted to resume being
the  exclusive  manufacturer  and  supplier  of  TA 1  Material  as  soon  as is
reasonably  feasible,  subject to: (i) reasonable and  appropriate  arrangements
being made to enable SPKK to recover or amortize  its start up costs  (including
without limitation the costs of additional clinical or other  trials)incurred to
replace on a temporary basis SciClone as the manufacturer and supplier of the TA
1 Material; and (ii) the requirements of Japanese law or regulations.

                  6.3.4       Specifications. All TA 1 Material manufactured and
supplied  hereunder shall be manufactured in conformity with the  Specifications
and in compliance  with  applicable  Japanese rules and  regulations,  including
cGMPs. The parties  understand and agree that the  Specifications may be revised
or supplemented  from time to time and as agreed by the parties,  or in order to
comply with government  regulations or to take into account Improvements,  Alpha
Improvements,   Alpha   Sublicensee   Improvements   and  SciClone   Sublicensee
Improvements,  where and to the extent the same has been  licensed  to the party
then manufacturing TA 1 Material.

                  6.3.5       Product  Introduction.  During  the  first six (6)
months after the first public  announcement  of the  introduction  of a Licensed
Product for  commercial  use, SPKK shall 


                                       12
<PAGE>


purchase  from  SciClone TA 1 Material to be used for marketing and promotion of
such Licensed  Product[*REDACTED]  and in such amounts and at such prices as are
set forth in the Commercial Supply Agreement.

                  6.3.6       Commercial Price.  [*REDACTED] SPKK shall use good
faith and commercially  reasonable efforts to obtain from MHW the most favorable
price for  Licensed  Products  and SPKK shall  consult  with  SciClone  and keep
SciClone fully informed concerning these efforts with MHW. [*REDACTED]

                  6.3.7       Payment. Payment for commercial requirements of TA
1 Material  ordered  hereunder shall be made in accordance with the terms of the
Commercial Supply Agreement.

                  6.3.8       Minimum  Purchase  Order.  SPKK  acknowledges  and
agrees that during the term of this  Agreement it shall be obligated to purchase
from  SciClone  such  quantities  of  TA  1  Material  as  are  consistent  with
commercially  reasonable  efforts  to market  and sell  Licensed  Products.  The
Commercial  Supply  Agreement for each  Licensed  Product shall set forth SPKK's
estimated  purchase  requirements for TA 1 Material for [*REDACTED].  During the
term of the Commercial Supply Agreement SPKK will, at least [*REDACTED] prior to
the beginning of each calendar  quarter prepare and provide to SciClone  rolling
estimated  purchase  requirements  for  TA 1  Material  for  [*REDACTED]  period
beginning  on the  first  day of the  quarter  [*REDACTED].  Estimated  purchase
requirements will be based on past sales and future sales forecasts generated by
SPKK for Licensed Products. Each of SPKK and SciClone acknowledge and agree that
for each such estimate the [*REDACTED]  purchase  requirements set forth therein
shall be binding on both parties, and that the remainder of such estimates shall
be non binding and are provided for information purposes only.

                  6.3.9       Effect of Improvements.  The parties agree that in
the event any Improvement,  Alpha Improvement,  SciClone Sublicensee Improvement
or  Alpha  Sublicensee  Improvement  has the  effect  of  reducing  the  cost of
processing,   manufacturing  or  producing  TA-1  Material,  the  parties  shall
negotiate a new Commercial Price so as to ensure, so far as is practicable, that
the parties share equally in the economic benefit of such Improvement.

                  6.3.10      Audit Rights. SciClone and SPKK each agree to keep
proper records and books of account and all proper entries  therein  relating to
the manufacture,  supply and Final Processing of Licensed Products. Either party
may cause an audit to be made of the  applicable  records of the other  party in
order to verify  any  price,  costs or  statements  rendered  hereunder,  at the
auditing party's expense.

         6.4. Final Processing of Licensed Products SPKK will be responsible for
and assume all costs  associated with Final  Processing,  quality  control,  and
storage of Licensed Products. [*REDACTED]

                    MARKETING AND SALES OF LICENSED PRODUCTS

         7.1.  Marketing  Coordinators.  No later  than six  months  before  the
estimated date of first commercial sale of the first Licensed Product hereunder,
the  parties  shall each  appoint  one  authorized  representative  (hereinafter
"Marketing  Coordinator") for the exchange of all communications  related to the
promotion  and  marketing  of  Licensed  Products  in  the  SPKK  Territory.  To
facilitate the commercialization of each Licensed Product in the SPKK Territory,
the Marketing Coordinators,  or such other representatives of the parties as are
agreed,  shall meet as needed, but no less than once every six (6) months.  Such
meetings  shall be at times and places agreed to by SPKK and  SciClone.  At such
meetings  the  parties  will  review the Budget,  discuss  the  Marketing  Plan,
coordinate the marketing objectives therein, set priorities thereunder,  discuss
and define the Specifications and quality control of Licensed Products. SciClone
agrees  that final  decisions  as to the  promotion  and  marketing  of Licensed
Products  shall be made by SPKK,  after giving due  consideration  to SciClone's
input.

         7.2.  Marketing  Plan.  SPKK  will  prepare  and  deliver  to  SciClone
[*REDACTED] a marketing plan for each of the Licensed  Products (the  "Marketing
Plan").

         7.3. Product Launch. Upon gaining the necessary regulatory, pricing and
reimbursement  approvals,  SPKK  agrees  to  work  diligently,  consistent  with
accepted business  practices and legal  requirements,  to launch,  promote,  and
commercialize  each Licensed Product,  devoting a comparable degree of attention
and  diligence to such  promotion  efforts as it devotes to the promotion of its
other pharmaceutical products of comparable market potential.

         7.4.  Marketing of Licensed Products. SPKK agrees and acknowledges that
as a condition to the license rights  contained in this Agreement,  SPKK and its
permitted  sublicensees  shall use only the Marks in connection with the sale or
advertising of Licensed Products, provided, however, that where SPKK offers good
cause as to why a Mark is unsuitable for  commercialization of Licensed Products
in the SPKK  Territory,  SciClone  shall file for and maintain,  at its expense,
during the term of this Agreement,  variations on any Mark [*REDACTED] to ensure
the optimal trademark for the SPKK Territory. SPKK and SciClone will discuss and
decide  jointly  prior to filing of the initial  NDA with  respect to a Licensed
Product  whether  it is most  advantageous  to the  parties  to market  Licensed
Products under a single or multiple Mark.

         7.5. Pre-existing Royalties. SPKK, or its designee,  shall pay directly
to such third  parties all royalties due to third parties on SPKK's Net Sales of
Licensed  Products,  including  those due to the  Universities,  Roche and Alpha
pursuant  to  the  Alpha  Agreement,  as  set  forth  in  Exhibit  I;  provided,
[*REDACTED]  of SPKK's Net Sales in any calendar  year;  and provided,  further,
that in the event any such third party royalty  shall expire or decline,  SPKK's
obligation hereunder shall be adjusted accordingly.

                  9.1.3     Binding  Agreement.  This  Agreement  is a legal and
valid  obligation  binding upon it and enforceable in accordance with its terms.
The execution, delivery and performance of this Agreement by such party does not
conflict with any agreement,  instrument or understanding,  oral or written,  to

regulation of any court,  governmental  body or  administrative  or other agency
having jurisdiction over it.

         9.2.  Representations  and  Warranties  of SPKK.  SPKK  represents  and
warrants  that it has had the  opportunity  to  fully  review,  and has  finally
reviewed the Alpha Agreement and the Prior  Agreements and understands the terms
and conditions stated therein.

         9.3.  Representations  and Warranties of SciClone. SciClone  represents
and  warrants  that it will use its  best  efforts  to  comply  with  the  Alpha
Agreement to the extent necessary to avoid  termination of the rights of SPKK to
develop and  commercialize  Licensed  Products in the SPKK  Territory.  SciClone
further  represents  and warrants that to its best knowledge the Marks are valid
and  subsisting  and that SciClone has received no actual notice that any of the
Marks infringe the rights of any third party.

         10.1.   Confidentiality.  During  the  term  of  this  Agreement,   and
thereafter,  each party  hereto will  maintain in  confidence  all  Confidential
Information  disclosed  by the  other  party  hereto.  Neither  party  will use,
disclose  or grant use of such  Confidential  Information  except  as  expressly
authorized  by this  Agreement.  To the extent that  disclosure is authorized by
this Agreement,  the disclosing  party will obtain prior written  agreement from
its employees,  agents, consultants or clinical investigators to whom disclosure

Each party will use at least the same standard of care as it uses to protect its
own trade  secrets or  proprietary  information  to ensure that such  employees,
agents,  consultants  and  clinical  investigators  do not  disclose or make any
unauthorized  use of such  Confidential  Information.  Each party will  promptly
notify the other upon  discovery of any  unauthorized  use or  disclosure of the
Confidential Information.

         10.2.  Exceptions.  Confidential  Information  shall  not  include  any
information which:

                                (i) was already  known to the  receiving  party,
other than under an obligation of  confidentiality  to the disclosing  party, at
the time of disclosure by the other party;

                                (ii) was  generally  available  to the public or
otherwise  part of the public domain at the time of its  disclosure to the other
party;

                                (iii) becomes generally  available to the public
or otherwise part of the public domain after its  disclosure  other than through
any act or omission of the receiving party in breach of this Agreement;

                                (iv) was disclosed to the receiving party, other
than  under  an  obligation  of  confidentiality,  by a Third  Party  who had no
obligation to the other party not to disclose such information to others;

                                (v) is required to be disclosed in a judicial or
administrative  proceeding  after all reasonable  legal remedies for maintaining
such information in confidence have been exhausted; or

                                (vi) is subsequently and independently developed
by employees,  consultants  or agents of the  disclosing  party without the aid,
application or use of any Confidential Information.

         10.3.  Authorized  Disclosure. Each party may disclose the Confidential
Information to the extent such  disclosure is reasonably  necessary in filing or
prosecuting  patent   applications,   prosecuting  or  defending  litigation  or
complying with applicable governmental regulations,  provided that if such party
is required to make any such disclosure of the Confidential  Information it will
to the extent  practicable give reasonable  advance notice to the other party of
such disclosure  requirement and, except to the extent inappropriate in the case
of  patent  applications,  will  use its best  efforts  to  secure  confidential
treatment of such information required to be disclosed.  To the extent necessary
to perform its obligations  under this Agreement,  SPKK may disclose (subject to
the confidentiality  restrictions contained herein) Confidential  Information to
investigators  and third party  contractors,  such as  potential  lyophilization
contractors, or suppliers of materials required for lyophilization and finishing
of  TA  l  Material  for  preclinical  and  clinical   studies   (provided  such
investigators and third parties execute  confidentiality  agreements  containing
terms no less strict than those contained herein).

         10.4.  Third Party Beneficiary. The parties agree that Alpha is a third
party  beneficiary of this  Agreement,  but only as it relates to  "Confidential

this Agreement  pertaining to such  "Confidential  Information"  as if it were a
party hereto.

         10.5. Press Releases. Prior to the Signing Date, SciClone has furnished
to SPKK a form of press release  which  SciClone is required by law to make with
respect to this  Agreement,  which press release has been approved by SPKK.  Any
additional or subsequent press releases by SciClone or SPKK with respect to this
Agreement or the subject matter hereof, or any right,  obligation or development
thereunder  (including,  without limitation,  any result of or development under
the Development  Program),  shall be subject to the prior review and approval by
the other party,  which approval shall not be unreasonably  withheld or delayed.
Under no circumstance  shall either party hereto quote or speak on behalf of the
other  party  without  the  specific  written  permission  of such other  party.
Notwithstanding anything to the contrary, if the applicable laws or governmental
regulations  obligate  a party  to issue a press  release,  the  party  shall be
entitled to do so,  although  the party  first  shall use good faith  efforts to
submit to the other party a draft of the proposed  press release and to give due
consideration to any suggested revisions recommended by the other party.

         10.6.  Agreement  Confidential.  The parties agree that the contents of
this Agreement shall constitute Confidential Information,  and as such, will not
be  disclosed by either party  without the prior  written  consent of the other,
except as required by law or prior  contractual  obligation,  and provided  that
such  written  consent  will  not be  unreasonably  delayed  or  withheld.  SPKK
understands and  acknowledges  that SciClone is obligated to file a copy of this
Agreement  with the  United  States  Securities  and  Exchange  Commission,  and
SciClone is authorized to do so without prior consent from SPKK.  SciClone shall
request the Securities and Exchange Commission to give confidential treatment to
sensitive  provisions of this  Agreement,  and will consult with SPKK concerning
such provisions.  The parties agree that  information  concerning this Agreement

                              INTELLECTUAL PROPERTY

         11.1.  Prosecution  and Maintenance of Alpha Patents. The Alpha Patents
shall be  prosecuted  and  maintained by SciClone,  Alpha or Roche,  as provided
under the Alpha  Agreement.  In the event SciClone  receives  notification  from
Alpha  that it does not  choose to  continue  prosecution  of one or more of the
Alpha  Patents and is able to transfer such rights to SciClone,  SciClone  shall
either take such actions as are  necessary to prosecute or maintain  such patent
application or patent, at its expense,  or, where  practicable,  shall give SPKK
not less than two (2) months' notice before any relevant deadline and SPKK shall
have the right to pursue, at its expense, prosecution of such patent application
or maintain such patent. In such event SciClone shall promptly assign its rights
therein to SPKK,  subject to the rights  retained by Alpha and Roche pursuant to
Section 10.1 of the Alpha Agreement. The transfer of any patent rights hereunder
shall not effect in any way SPKK's obligations to make all payments set forth in
this  Agreement.  In the event of  termination  or expiration of this  Agreement
pursuant  to  Article  12,  SPKK  shall re



                                       17
<PAGE>

assign any such patent or patent application to SciClone upon SciClone's request
and  pursuant  to  Alpha's  request  of the same from  SciClone,  to the  extent
practicable  within  thirty  (30)  days  after the date of such  termination  or
expiration and upon  reimbursement  by SciClone to SPKK of all costs incurred by
it for the prosecution and maintenance of such patents or patent applications.

         11.2. Prosecution and Maintenance of SciClone Patents. SciClone Patents
shall be prosecuted and maintained by SciClone, at its expense;  provided,  that
in the event SciClone  elects not to pursue  prosecution of any patent or patent
application contained in the SciClone Patents, SciClone shall give SPKK not less
than two (2) months' notice before any relevant deadline and SPKK shall have the
right to pursue, at its expense, prosecution of such patent application. In such
event SciClone shall promptly assign its rights therein to SPKK. The transfer of
any patent rights  hereunder  shall not effect in any way SPKK's  obligations to
make all payments set forth in this Agreement.

         11.3. Joint Patent Applications or Inventions.

                  11.3.1    Inventions.  Each of SciClone and SPKK shall be free
to determine those SciClone  Inventions or SPKK Inventions,  respectively,  upon
which it chooses to file one or more patent applications in accordance herewith.
In the event  SciClone  or SPKK  determines  to file a patent  application  with
respect to any SciClone  Invention or SPKK Invention,  respectively,  that party
shall  conduct such patent  prosecution  process  (including  interferences  and
foreign  oppositions)  according  to its own  internal  standards  so as to most
effectively  cover such  Invention for use by both SciClone and SPKK.  The other
party shall have full rights of consultation with the filing party's counsel and
any  outside  patent  attorney  with  respect  to a  patent  application  on any
Invention.  The filing  party  shall also  promptly  deliver to the other  party
copies of all patent applications,  amendments, related correspondence and other
related matters. All expenses associated with the prosecution and maintenance of
all patent applications described herein shall be borne by the filing party.

                  11.3.2    Joint Inventions. The parties will jointly determine
whether to seek patent  protection for any Joint Invention.  SciClone shall have
the responsibility for promptly filing patent  applications on Joint Inventions.
The  expense  of  preparing,   filing,   prosecuting  and   maintaining   patent
applications  on Joint  Inventions  shall be borne  [*REDACTED].  All such joint
patent  applications  shall be mutually approved by the parties and filed in the
name of SciClone and SPKK,  or their  designees,  [*REDACTED].  In the event the
parties do not mutually  agree to proceed with a patent  application  on a Joint
Invention, the party wishing to file may do so at its own expense.

                  11.3.3    Abandonment. In the event either party elects not to
pursue prosecution of a patent application described in Section 11.3.1 or 11.3.2
above  (including  any  foreign   counterpart   application  of  a  U.S.  patent
application  filed) or pay any annuity as it becomes due,  such party shall give
the  other  party not less  than two (2)  months'  notice  before  any  relevant
deadline  and such other party shall have the right to pursue,  at its  expense,
prosecution of such

patent application. In such event the abandoning party shall promptly assign its
rights therein to the other party.

                  11.3.4    No Representation.  Each party specifically excludes
any  representation or warranty,  express or implied,  that it will successfully
obtain any patent on any Invention or Joint Invention.

         11.4.   Assignments.

                  11.4.1    Inventions.  or Program Data Each party to which any
portion of the  Inventions  or Program Data vests other than as intended and set
forth  in  this  Agreement  shall,  to the  extent  required  by the  intent  or
provisions  herein,  immediately  assign to the other  such  right,  title,  and
interest  therein.  Each party agrees to  cooperate  with the other and take all
reasonable  additional  actions and execute such  agreements,  instruments,  and
documents  as may be  reasonably  required  to  perfect  the  other's  ownership
interest in accordance  with the intent of this Article 11,  including,  without
limitation,   the  execution  of  necessary  and   appropriate   instruments  of
assignment.

                  11.4.2    Joint  Inventions.  Each party  agrees not to assign
any rights to the Joint Inventions (except to its Affiliates)  without the prior
written consent of the other party.

         11.5.   Patent   Marking.  SPKK  shall  mark  all   Licensed   Products
manufactured,  used  or  sold  under  the  terms  of this  Agreement,  or  their
containers, in accordance with the applicable patent marking laws, as required.

         11.6.  Enforcement.  In the event SciClone or SPKK becomes aware of any
actual or threatened  infringement or  misappropriation of any Alpha Technology,
SciClone  Technology,   Alpha  Sublicensee   Technology,   SciClone  Sublicensee
Technology or  Improvements,  that party shall promptly notify the other. In the
case of infringement of Alpha Technology,  the parties acknowledge that pursuant
to Section 13.2 of the Alpha  Agreement,  SciClone shall have the first right to
bring an infringement  action against the third party  infringer.  To the extent
allowed under Section 13.2 of the Alpha Agreement, Alpha shall have the right to
bring  such  an  action  in the  event  SciClone  elects  not to  bring  such an
infringement  action.  In the further event that Alpha elects not to pursue such
infringement action, it shall so notify SPKK, in which event SPKK shall have the
right to bring such  action,  at its own  expense,  and in  accordance  with the
requirements of Section 13.2 of the Alpha Agreement.

         11.7.  Patent  Term.  Extensions  SciClone  and SPKK  shall  reasonably
cooperate  to obtain the  benefits  of any patent  term  extension  which may be
available for any patent subject to this Agreement.

         11.8.   Trademarks.

                  11.8.1    Ownership   of  Marks.   SPKK  hereby   acknowledges
SciClone's  ownership of the Marks and covenants  that SPKK shall not contest or
challenge,  directly or indirectly,  the validity of the Marks at any time. Such
Marks shall bear the  designation  TM or the  designation R within a circle,  as
specified by SciClone.  If SPKK, in the course of marketing and  distribution of




                                       19
<PAGE>

the Licensed  Products,  acquires any goodwill or reputation  in the Marks,  all
such  goodwill  or  reputation  shall   automatically   vest  in  SciClone  upon
termination or expiration of this Agreement,  without  separate payment or other
consideration to SPKK.

                  11.8.2    Defense of Marks. In the event SPKK becomes aware of
any actual or threatened  infringement of the Marks in the SPKK Territory,  SPKK
shall  promptly  notify  SciClone.  SPKK  shall,  at the  request and expense of
SciClone,  do such acts or things as  SciClone  may  reasonably  require for the
purpose of obtaining, maintaining,  enforcing and preserving any of the Marks in
the SPKK Territory;  provided,  however, that SPKK agrees that only SciClone has
the right to enjoin any  infringement  or  registration  by a third party of the
Marks;  except that, in the event SciClone elects not to seek to enjoin any such
infringement  or  registration,  SPKK shall have the right,  at its election and
expense,  to do so. SPKK agrees to cooperate  fully with SciClone at the expense
of  SciClone  if  SciClone  sues to enjoin  such  infringements  or to oppose or
invalidate any such registration.

                  11.8.3    Registration.  SciClone acknowledges and agrees that
within  fourteen  (14)  business  days after the Signing Date it shall file this
Agreement with the Japanese Trademark Authorities for the purpose of registering
SPKK  therewith  as a  licensee  of the  Marks.  If  any  additional  filing  or
registration  is required by  applicable  Japanese law to so register  SPKK as a
licensee of the Marks,  SciClone  shall do so. Costs for the foregoing  shall be
borne by SPKK as specified in Section 17.1 hereof.

Effective  Date and expire upon the last to occur of: (i))  [*REDACTED]  or (ii)

distinguished  from an early termination of this Agreement),  SPKK shall enjoy a
non  exclusive,  royalty  free,  paid up license to all licenses  from  SciClone
granted pursuant to this Agreement (including,  without limitation, the right to
use the Marks upon expiration), subject to Sections 2.2.2 and 12.2 hereof.

         12.2. Extension or Renewal; Right to Marks. Prior to expiration of this
Agreement, SPKK and SciClone shall, where mutually beneficial, negotiate in good
faith to extend or renew this Agreement  and/or the Commercial  Supply Agreement
with the objective of continuing the relative  economic  benefits enjoyed by the
parties  prior to  expiration,  but taking into  account the  expiration  of the
relevant patents.  In the event this Agreement is terminated by SPKK pursuant to
Section  12.4.2,  SPKK shall  retain  the right and  license to use the Marks as
provided for in this  Agreement.  In the event this  Agreement is  terminated by

         12.3.  Termination by SciClone.  SciClone may, in its sole  discretion,
terminate this Agreement,  effective after the grace periods described below, by
giving written notice of such  termination to SPKK, if SPKK fails to comply with
any material obligation of this Agreement, including without limitation, failure
of SPKK to perform any of its material development obligations under Section 3.3
and  Exhibit  D, or failure of SPKK to make any  payments  when due and  payable
hereunder  (except  payment of amounts that are under bona fide dispute by SPKK,
which dispute shall then be resolved promptly under the provisions of Article 15
hereof),  and SPKK  fails to cure such  failure  within  sixty  (60) days  after
written notice thereof by SciClone; provided, however, that if SPKK is unable to
cure a failure  for causes  beyond its  reasonable  control  pursuant to Section
17.8,  then such sixty (60) day period  shall be  extended  for a period of time
reasonable under the circumstances.  Upon effective termination by SciClone, all
payments then outstanding under this Agreement shall become  immediately due and
payable. Upon any such termination by SciClone, all licenses from SciClone shall
terminate.

         12.4. Termination by SPKK.

                  12.4.1  Termination Without Cause.

                      (a) Notwithstanding any provision in this Agreement to the
contrary,  SPKK shall have the right to  terminate  this  Agreement  [*REDACTED]
SciClone of SPKK's intent to so terminate.  Within  [*REDACTED]  days after said
notice of intent,  the CEOs of SPKK and SciClone  shall meet in Japan to discuss
said notice of intent to  terminate  (unless such CEOs have agreed in writing to
an alternative process).

                      (b) If SPKK  gives  notice  of intent  to  terminate  this
Agreement with respect to both the CHB and CHC indications,  then at any time(s)
after the [*REDACTED], SciClone shall give to SPKK all data then available which
reasonably  supports the commercial and/or scientific  feasibility of the use of
TA-1 for other  indications  in Japan and a  written  plan and  budget as to the
development  of such  other  indication(s)  (excluding  CHB and  CHC),  of which
SciClone  is aware,  whereupon  SPKK  shall  have  sixty (60) days to deliver to
SciClone a written  commitment  to so develop  and  commercialize  the  SciClone
Technology  for said  indication(s);  and if SPKK does not so commit,  then SPKK
shall have no further rights with respect to said indication(s).

                      (c) During the [*REDACTED]  period following any notice of
intent to terminate given hereunder by either party, [*REDACTED].

                      (d)  After  receipt  of  any  SPKK  notice  of  intent  to
terminate, SciClone shall have the right to offer to any third party, whether in
or outside of the SPKK Territory,  the right to develop, use and sell TA 1 based
products for any such rejected  indication,  although such rights may be granted
to the third party only upon the  effective  date of the  termination  of SPKK's
rights to said indication(s).

                      (e) If SPKK terminates this Agreement with respect to both
the CHB and CHC indications, then SPKK shall have no further rights with respect
to CHB and CHC  indications;  and SPKK's rights for all  additional  indications
shall cease  [*REDACTED]  following said  termination as to both the CHB and CHC
indications,  excepting  only that  SPKK's  rights  under this  Agreement  shall
continue  in full  effect for any  indication(s)  with  respect to which SPKK is
pursuing and continues to pursue diligent  development and/or  commercialization
efforts.

                      (f)  At the  time  SPKK  terminates  this  Agreement  with
respect to a particular  indication(s),  if SPKK has already  then  obtained the
required  regulatory  and pricing  approvals for marketing and selling  Licensed
Products for said rejected indication(s), then SciClone [*REDACTED] of net sales
(defined according to the definition of Net Sales, mutatis mutandis) in Japan by
SciClone or any new third party licensee of any such product(s) for the rejected
indication(s).  The rate of said  [*REDACTED]  shall  depend  upon the  economic
feasibility for SciClone and/or such new third party licensee to make a fair and
customary profit and return of investment, and still have revenues from the sale
of Licensed Products  available to fund said  [*REDACTED].  If SciClone and SPKK
are not able to reach mutual agreement as to the amount of [*REDACTED] then such
[*REDACTED]  shall be determined  pursuant to binding  arbitration in accordance
with the  provisions  of  Exhibit  J  hereof.  SciClone's  [*REDACTED]  incurred
pursuant to this Section  12.4.1 shall be  [*REDACTED]  incurred by SPKK for the
rejected  indication(s)  during the period  commencing  on the Signing  Date and
ending on the effective  date of termination of this Agreement with respect to a
particular indication(s) under this Section 12.4.1.

                  12.4.2    Termination   For   Breach.   SPKK,   in  its   sole
discretion,  may terminate this Agreement at any time,  effective after the cure
period  described  below,  by  giving  written  notice  of such  termination  to
SciClone,  if SciClone  fails to comply  with any  material  obligation  of this
Agreement  and SciClone  fails to cure such  failure  within  [*REDACTED]  after
written notice thereof by SPKK, provided, however, that if SciClone is unable to
cure a failure for causes beyond its reasonable control pursuant to Section 17.8
hereof,  then such [*REDACTED] shall be extended for a period of time reasonable
under the circumstances. Upon any termination of this Agreement pursuant to this
Section 12.4.2, all licenses from SciClone shall continue in effect,  subject to
SPKK making payments to SciClone as  contemplated  by Section 6.3.6 hereof,  and
subject to  reasonable  renegotiation  of Section  6.3.6 to reflect  the changed
contributions of the parties.

         12.5.   Effect of Termination.

                  12.5.1    Survival.   Notwithstanding   any   termination   or
expiration,  the  provisions  of Article 4, other than Sections 4.2 and 4.4, and
Articles 9, 10, 11, 12, 13, 14, 15 and 17, and Section 7.4 shall  survive to the
extent required therein.

                  12.5.2    Data Regulatory  Filings.  Upon  termination of this
Agreement  by SciClone in  accordance  with 12.3,  or upon  termination  of this
Agreement  by SPKK in  accordance  with  Section  12.4.1,  SPKK  shall  promptly
transfer or assign to SciClone  (or its  designee),  to the extent

authorities with respect to the Licensed Products, and shall deliver to SciClone
any and all Program Data and Improvements, and any and all Licensed Products and
TA 1 Material in its  possession.  SciClone shall pay to SPKK SPKK's actual cost
of such Licensed Products and TA 1 Material.

         12.6.  SciClone  Retained  Rights.  Notwithstanding   anything  to  the
contrary  contained  in this  Agreement,  in the event  that this  Agreement  is
terminated  pursuant to Sections 12.3 or 12.4.1,  then:  (a) SciClone shall have
full rights (and SPKK shall have no rights) to (i) develop, commercialize,  make
and sell Licensed  Products,  (ii) use Alpha  Technology,  SciClone  Technology,
SciClone  Sublicensee  Technology,   Alpha  Sublicensee   Technology,   SciClone

representation  made or  warranty  given by SPKK with  respect  to any  Licensed
Product,  provided  that  SciClone  (i) gives SPKK  notice of such  claim,  (ii)
cooperates with SPKK, at SPKK's expense, in the defense of such claim, and (iii)
gives SPKK the right to control the defense  and  settlement  of any such claim,
except that SPKK shall not enter into any  settlement  which affects  SciClone's
rights or interest without SciClone's prior written approval; provided, however,
that SPKK  shall not so  indemnify  and hold  SciClone  harmless  for any Claims
arising from defects in any TA 1 Material supplied by SciClone which are present
at the time of acceptance of such TA 1 Material by SPKK.  SciClone shall have no
authority to settle any claim on behalf of SPKK.

or at such other place as Lender may from time to time designate in writing, the
principal sum of Ninety-Five  Thousand Dollars  ($95,000),  with interest on the
unpaid balance of principal from the date of this Note until paid at the rate of
7.375% per annum (the "Note Rate"), on the following terms:

     I.  Payment.  The principal and interest due pursuant to this Note shall be
paid as follows:

          A. The entire principal balance with all accrued interest shall be due
and  payable on July 14,  1997,  unless the term  hereof is renewed as set forth
herein.  At the  election of the Lender,  the Lender may extend the term of this
Note,  which extension shall be deemed effective upon written notice from Lender
to  Borrowers  delivered  at any time before the initial  maturity  date hereof,
which notice shall state the extended  maturity date  selected by Lender.  As of
the effective  date of such notice,  this Note shall be extended on all the same
terms and conditions as are set forth herein,  except for the extended  maturity
date.

          B.  Principal  and  interest  shall be payable in lawful  money of the
United  States.  Interest  shall be  calculated  on the basis of a 360-day  year
consisting  of 12  thirty-day  months.  Each payment  shall be applied  first to
interest  then due and the balance of said  installment  shall be applied to the
principal sum.

          C.  This Note may be prepaid at any time, without penalty.

     II. Security. This Note is secured by a deed of trust of even date herewith
made by Borrowers,  as trustor, to Western Title Company,  Inc., as trustee, for
Lender, as beneficiary (the "Deed of Trust"),  encumbering certain real property
commonly known as 771 Burgundy Road, Incline Village, Nevada (the "Property").

     III. Default and Acceleration.

          A. Unless  otherwise  prohibited by law, upon the occurrence of any of
the  following  events,  the Lender of this Note shall have the option,  without
demand or notice,  to  declare  the entire  balance  of  principal  of this Note
together with all accrued interest to be immediately due and payable:



<PAGE>

               1. Borrowers default in the payment of principal or interest when
due pursuant to the terms hereof or default in the performance of any  obligaton
of Borrowers in the Deed of Trust or any other deed of trust, security agreement
or other agreement (including any amendment,  modification or extension thereof)
which may  hereafter be executed by Borrowers  for the purpose of securing  this
Note; or

               2.  Borrowers  voluntarily  or by operation of law sell,  convey,
assign,  further  encumber or  otherwise  transfer  or agree to sell,  convey or
otherwise  transfer,  all or substantially all, or any portion of, or Borrowers'
interest in the Property.

     IV. Default Interest Rate. If Borrowers fail to make payment within fifteen
(15) days after payment becomes due and payable,  Borrowers are  to pay interest
on the late payment,  including  that portion of the late payment which consists
of past-due  interest,  at an annual rate (the "Default  Rate") of three percent
(3.0%) in  excess  of the Note  Rate,  from the date the  payment  was due until
Borrowers pay in full all sums due under this Note.

     V. Attorneys' Fees. In the event of any default hereunder, Borrowers hereby
promise to pay all costs of collection,  including  reasonable  attorneys'  fees
incurred by Lender hereof on account of such collection,  whether or not suit is
filed hereon.

     VI.  Waiver.  The waiver by Lender hereof of any breach of or default under
any term,  covenant or condition  contained  herein or in any of the  agreements
referred to above  shall not be deemed to be a waiver of such term,  covenant or
condition  or any  subsequent  breach of or default  under the same or any other
such term, covenant or condition.

     VII. No Usury.  It is the intent of  Borrowers  and Lender that the rate of
interest on the  indebtedness evidenced hereby shall not exceed the maximum rate
permitted by applicable law and accordingly,  if the rate of interest  specified
herein, or any other payments  specified herein or otherwise required to be made
by Borrowers or received by Lender in connection with the indebtedness evidenced
hereby and deemed to be  interest,  shall  exceed the  maximum  rate of interest
permitted by applicable law then such  payments,  to the extent they exceed such
maximum rate, shall be deemed to have been made and received inadvertently,  and
shall  for all  purposes  be deemed to be a  payment  of and on  account  of the
principal  balance  of the  indebtedness  evidenced  hereby and shall be applied
accordingly or, at Lender's option, returned to Borrowers.

     VIII. General  Provisions.  This Note shall be governed by and construed in
accordance with the laws of the State of California.  The makers, guarantors and
endorsers of this Note hereby severally waive  presentment for payment,  protest
and demand, notice of protest,  demand and dishonor and nonpayment of this Note,
and consent that Lender may extend the time for payment or otherwise  modify the
terms of payment of any part or the whole of the debt evidenced by this Note, at
the request of any person  liable  hereon, and such  consent shall not alter nor
diminish the liability of any
