                               PROSPECTUS SUMMARY

      The  following  summary is qualified in its entirety by the more  detailed
information  and financial  statements,  including the notes thereto,  appearing
elsewhere in this Prospectus or incorporated  herein by reference.  The material
herein contains certain forward-looking  statements,  including;  (i) statements
regarding the  application  of ZADAXIN  thymosin alpha 1 in disease areas beyond
chronic  hepatitis  B; (ii) the use of CPX as a  potential  chronic  therapy for
cystic fibrosis; (iii) the potential for regulatory approvals of ZADAXIN and the
launching of ZADAXIN in  additional  markets;  (iv) the  Company's  expectations
regarding  increases  in revenues  from ZADAXIN and  increases in marketing  and
research  and  development  expense  levels;  and (v) the  Company's  intent  to
commence  preclinical  development of certain  compounds.  These  statements are
subject  to  certain  risks and  uncertainties.  These  risks and  uncertainties
include:  (i)  reliance by the  Company on a single  product,  ZADAXIN,  for its
revenues;  (ii) the absence of  regulatory  approval for ZADAXIN in  significant
markets;  (iii) the expensive,  time consuming and uncertain regulatory approval
process;  (iv) risks associated with the manufacture and supply of ZADAXIN;  (v)
competition  from  competing  therapies;  and (vi)  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 reports
filed with the Commission.

                                   The Company

      The Company is an emerging pharmaceutical company that acquires, develops,
and commercializes  specialist-oriented  (e.g.,  hepatologists,  oncologists and
pulmonologists),  proprietary  drugs for treating  chronic and  life-threatening
diseases for which there are no adequate treatment modalities, including chronic
hepatitis B, chronic  hepatitis C, cancer,  immune  system  disorders and cystic
fibrosis.  The Company  currently  has two  products  in  clinical  development,
ZADAXIN thymosin alpha 1 and CPX, as well as several preclinical candidates.

   
      ZADAXIN, a synthetic  immunomodulator (i.e., immune system regulator),  is
the  Company's  lead product.  In the United  States and Europe,  the Company is
developing  ZADAXIN in combination  with interferon for the treatment of chronic
hepatitis C. The Company is currently exploring  collaborative  arrangements for
the  development  of ZADAXIN in these  territories.  In Japan,  the  Company has
licensed  exclusive  rights to ZADAXIN to  Schering-Plough  K.K.  ("SPKK"),  the
Japanese subsidiary of Schering-Plough Corporation, the world's leading marketer
of viral  hepatitis  therapies.  SPKK has completed phase 1 and phase 2 clinical
studies of ZADAXIN for the treatment of chronic hepatitis B. SPKK is expected to
commence a pivotal phase 3 study of ZADAXIN in chronic hepatitis B in the fourth
quarter of 1997. In November 1997, the Company announced that SPKK has commenced
the  enrollment  of  patients  in a  phase  2  study  of  thymosin  alpha 1 as a
monotherapy for hepatitis C, as required by the Japanese  Ministry of Health and
Welfare  (MOHW) for approval of the drug for the  treatment of hepatitis C. SPKK
is also  working to satisfy  MOHW  requirements  to begin a clinical  program to
study  the  use of its  INTRON  A(R)  (interferon  alfa - 2b) and  ZADAXIN  as a
combination  therapy for  hepatitis C.  ZADAXIN is currently  approved and being
marketed  for  chronic  hepatitis B in China,  the  Philippines  and  Singapore.
Furthermore,  the  Company  has filed for  approval  to market  ZADAXIN for this
indication  in 14  additional  countries in Asia,  Latin  America and the Middle
East.  SciClone licensed  thymosin alpha 1 from Alpha 1 Biomedicals  ("Alpha 1")
and has  worldwide  marketing,  development  and  manufacturing  rights with the
exception  of  Japan,  Italy,  Spain  and  Portugal,   where  rights  have  been
sublicensed.  Chronic  hepatitis B is the second most common chronic  infectious
disease worldwide.  The World Health  Organization  estimates that approximately
350 million individuals worldwide, or 5% of the world's population, are carriers
of the virus, the majority of whom are located in Asia.

      CPX, the Company's  second product in clinical  development,  is an orally
administered  synthetic  compound  discovered  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 regulator ("CFTR") gene. CPX is an orally administered compound that
targets the biochemical  abnormality at the root cause of CF, the malfunctioning
CFTR  protein.  In vitro  studies  from the NIH have shown that CPX binds to the
CFTR and permits the CFTR to enhance the  performance of its chloride  secretion
function. In October 1997, Dr. Harvey Pollard of the Uniform Services University
of  Health  Services  and  formerly  of  the  NIH,  presented  preclinical  data
demonstrating  that CPX is the  only CF drug in  clinical  development  that can
correct the two fundamental problems caused by the most common genetic defect in
CF patients,  abnormal  trafficking  and impaired  chloride ion  transport.  The
Company obtained orphan drug status for CPX from the United States Food and Drug
Administration ("FDA") in April 1997 and was awarded a phase 1 Orphan Drug

                                       4
<PAGE>
Grant from the FDA in  October  1997.  The  Company is  currently  conducting  a
multicenter  phase 1  clinical  study in the U.S.  involving  patients  with CF.
SciClone's phase 1 program for CPX is the first to attempt to measure both sweat
chloride and nasal epithelial  transmembrane  potential difference ("NEPD") in a
multicenter  trial.  The Cystic Fibrosis  Foundation  supported  SciClone in its
Investigational  New Drug ("IND")  filing with the FDA to gain approval to begin
the testing of CPX  directly in CF  patients  rather than the normal  process of
testing first in healthy, normal volunteers.
    


      The Company  has  additional  compounds  under  license.  During the first
quarter of 1998, the Company plans to commence preclinical development of one of
these compounds.  Targeted indications for this compound include epilepsy, to be
studied at the NIH, and multiple drug resistance in cancer, to be studied at the
U.S. National Cancer  Institute.  The Company also plans to evaluate activity of
certain of its other preclinical candidates in 1998.

      Internationally,  SciClone has entered into over 25 exclusive distribution
arrangements to register and market ZADAXIN.  The Company intends to out-license
its products  where a  collaborative  arrangement  will  materially  enhance the
prospects for a drug's  commercial  success,  such as the Company's license with
SPKK for exclusive rights to develop and market ZADAXIN in Japan. The Company is
currently  seeking a  collaborative  arrangement  in the U.S. and Europe for the
phase 3 development  of ZADAXIN in chronic  hepatitis C. The Company  intends to
source ZADAXIN,  CPX and any future products through contract  manufacturing and
supply  agreements.  The Company has entered into supply  agreements in the U.S.
and Europe for the supply of bulk and  finished  product  thymosin  alpha 1. The
Company  currently  contracts with a major U.S.  pharmaceutical  company for the
supply  of  bulk  CPX  and  another  U.S.  pharmaceutical  manufacturer  for the
finishing of CPX.

     Common Stock (the "Pledged  Shares") as security for a $5,944,000 loan from
     the Company (the  "Shareholder  Loan") which has been recorded as an offset
     to  shareholders'  equity at September 30, 1997.  Immediately  prior to the
     consummation  of any offering,  the Company may elect to cancel,  through a
     non-cash  exchange,  a number of the Pledged  Shares in partial or complete
     satisfaction of the  Shareholder  Loan,  including  accrued  interest.  The

     reference  to the  price of the  shares  to be sold in such  offering  less
     permitted  discounts.  If the  Company  elects  to  exercise  such  option,
     immediately prior to the closing of this offering,  in full satisfaction of
     the Shareholder Loan and accrued  interest then,  assuming a price of $5.03
     per share less permitted  discounts,  the Company would cancel 1,547,157 of
     the Pledged Shares,  and Common Stock  outstanding  after this offering and
     total   shareholders'   equity,  as  adjusted,   would  be  16,992,329  and
     $25,355,000, respectively. See "Recent Developments."

                                  RISK FACTORS

      In  addition  to the other  information  in this  Prospectus,  prospective
investors  should  consider the following risk factors in evaluating the Company
and its  business  before  purchasing  any of the  Shares  offered  hereby.  The
material herein contains  certain  forward-looking  statements,  including:  (i)
statements  regarding the application of ZADAXIN in disease areas beyond chronic
hepatitis B; (ii) the use of CPX as a therapeutic treatment for cystic fibrosis;
(iii) the  potential  for  regulatory  approvals of ZADAXIN and the launching of
ZADAXIN  in  additional  markets;  (iv)  the  Company's  expectations  regarding
increases in revenues  from ZADAXIN and  increases in marketing and research and
development expense levels; and (v) the Company's intent to commence preclinical
development of certain compounds.  These statements are subject to certain risks
and  uncertainties.  These risks and  uncertainties  include:  (i) reliance on a
single  product,  ZADAXIN,  for its  revenues;  (ii) the  absence of  regulatory
approval for ZADAXIN in significant markets; (iii) the expensive, time consuming
and  uncertain  regulatory  approval  process;  (iv) risks  associated  with the
manufacture and supply of ZADAXIN; (v) competition from competing therapies; and
(vi)   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 reports filed with the Commission.

      Dependence on ZADAXIN and CPX. The Company's principal development efforts
are currently focused primarily on ZADAXIN.  Clinical trials of thymosin alpha 1
sponsored  by the Company  and/or  other  parties are  currently  in progress or
planned  and  favorable  results  from such  trials  will be  necessary  to gain
regulatory approval in significant  markets.  Sales of ZADAXIN commenced in 1997
but are not  significant  at this time.  While  ZADAXIN  has been  approved  for
commercial sale for treatment of chronic  hepatitis B in China,  the Philippines
and Singapore, no assurance can be given that ZADAXIN approvals will be obtained
in additional countries or for the treatment of additional indications,  such as
chronic  hepatitis  C, 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 depend on market  acceptance  and successful  distribution.  In particular,
while China is the largest potential market for ZADAXIN,  the low average income
and poorly developed  distribution  infrastructure present ongoing challenges to
successful  development of the market.  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.

      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.

   
      No Significant  Revenues;  Continuing  Operating  Losses.  The Company has
never generated significant revenues from the commercialization of its products,
and there is  substantial  uncertainty  regarding  the  timing and amount of any
future revenues.  The Company cannot predict when or if marketing  approvals for
CPX will be obtained  or  additional  marketing  approvals  for ZADAXIN  will be
obtained.  Even if such  approvals are obtained,  there can be no assurance that
ZADAXIN and CPX will be successfully commercialized. The Company has experienced
significant  operating losses since its inception and, as of September 30, 1997,
had an accumulated deficit of approximately  $81.1 million.  The Company expects
its operating expenses to increase over the next several years as it expands its
development,  clinical testing and marketing capabilities. The Company's ability
to  achieve a  profitable  level of  operations  is  dependent  in large part on
successful  expansion  of the Asian  market for  ZADAXIN,  obtaining  additional
regulatory  approvals for its ZADAXIN product and/or future  products,  entering
into   agreements  for  product   development   and   commercialization,   where
appropriate,   and  continuing  to  expand  from   development  into  successful
marketing.  There can be no  assurance  that the  Company  will  ever  achieve a
profitable level of operations.
    

      Future Capital Needs;  Uncertainty  of Additional  Financing.  The Company
anticipates  that  the net  proceeds  from  this  offering,  together  with  the
Company's  available cash and expected  interest income thereon will be adequate
to satisfy its capital  requirements until mid-1999.  However,  the Company will
need additional financing to support its long-term product development programs.
The Company's future capital requirements will depend on many factors, including

                                       7
<PAGE>

progress  with  preclinical  testing  and  clinical  trials,  the  time and cost
involved  in   obtaining   regulatory   approvals,   patent   costs,   competing
technological  and  market  developments,   changes  in  existing  collaborative
relationships,   the  Company's   ability  to  establish   development,   sales,
manufacturing  and  marketing  arrangements.  No  assurance  can be  given  that
adequate financing will be available to the Company on a timely basis or at all.

      Dependence on Third Parties.  The Company's strategy  contemplates that it
will enter into various  arrangements with other entities.  To date, the Company
has  acquired  rights to ZADAXIN  and certain  other drugs but is only  actively
pursuing development of ZADAXIN and CPX. Failure to license or otherwise acquire
rights  to  additional  drugs  would  result  in  a  shortage  of  products  for
development.  In  addition,  the Company has  licensed  exclusive  rights to the
development  and  commercialization  of  ZADAXIN  in Japan  to SPKK.  SPKK has a
substantial  commitment to alpha  interferon,  which is an approved  therapy for
chronic hepatitis B and chronic hepatitis C in Japan.  There can be no assurance
that either of these arrangements will prove successful or that the Company will
be able to  negotiate  additional  arrangements  in the  future.  The amount and
timing of  resources  that  collaborators  devote to their  activities  with the
Company  will not be within the  control of the  Company  and may be affected by
financial difficulties or other factors affecting these third parties. There can
be no assurance  that such parties will perform their  obligations  as expected.
Moreover, the Company's ability to obtain regulatory approval in one country may
be delayed or  adversely  affected by the timing of  regulatory  activities  and
approvals in one or more other  countries,  particularly if the Company does not
participate  in the regulatory  approval  process in such other  countries.  See
"Business -- Manufacturing" and "-- Marketing and Sales."

   
      Foreign Sales and  Operations.  The Company's  financial  condition in the
near term 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. The majority of the Company's current
sales  are to  customers  in  China  where  the  Company's  accounts  receivable
collections  are typically 180 days or greater.  Such  collections  to date have
been  slower  than  anticipated  and the  Company is  currently  monitoring  the
situation.  If collection of outstanding accounts receivable does not improve by
year-end,  it may become  necessary to increase the related  allowances  for bad
debts or slow the rate of sales to this market.

      Patents and Proprietary Rights.  Certain composition of matter patents for
thymosin  alpha 1 expired in October  1997.  The  Company may in the future have
only  limited  composition  of  matter  patents  for  thymosin  alpha 1 or other
products.  However,  the  Company  owns or has  exclusive  licenses  for use and
process patents or patent  applications in the U.S. and other  jurisdictions for
thymosin alpha 1 and CPX and will seek to protect such products from competition
through such patent protection and through other means. See "Business -- Patents
and Proprietary Rights." 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.  Numerous patents and patent applications relating to thymosin alpha 1
are held under  exclusive  license and the breach by the Company of the terms of
such license  could result in the loss of the  Company's  rights to such patents
and patent applications.  Other companies obtaining patents claiming products or
processes  useful to the  Company  may bring  infringement  actions  against the
Company and such litigation is typically costly and time-consuming. 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

                                       8
<PAGE>

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.

      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 patents and proprietary rights in
many countries in SciClone's ZADAXIN territory can be expected to be problematic
or unpredictable.  There can be no assurance that any patents issued or licensed
to the  Company  will  provide  it with  competitive  advantages  or will not be
challenged by others. No assurance can be given that holders of patents licensed
to the  Company  will  file,  prosecute,  extend or  maintain  their  patents in
countries where the Company has rights.  Furthermore,  there can be no assurance
that others will not  independently  develop similar products or will not design
around patents issued or licensed to the Company.

      Government  Regulation and Product  Approvals.  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 and  requires  the
expenditure  of  substantial  resources.  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   sponsoring  clinical  trials  and  pursuing  regulatory
approvals of ZADAXIN in a number of countries and of CPX in the U.S.,  but there
can be no assurance that the Company will be able to complete such trials,  that
such trials, if completed, will fulfill regulatory approval criteria or that the
Company will ultimately  obtain approvals in such countries.  Adverse results in
such program could result in the placement of restrictions on the use of ZADAXIN
and CPX or  revocation of the  approval.  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 the applicable  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 which could prevent or delay regulatory approval of ZADAXIN,  CPX or any
future products of the Company.

   
      Manufacturing.  The Company has entered into  contract  manufacturing  and
supply agreements to source ZADAXIN and CPX. 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 an
acceptable  cost.  While  the  Company  believes  it has and will be able in the
future to  establish  manufacturing  relationships  with  experienced  suppliers
capable of meeting  the  Company's  needs,  there can be no  assurance  that the
Company will establish long term  manufacturing  relationships with suppliers or
that these suppliers will prove satisfactory.  The Company currently has vialing
and  packaging  supply  agreements  in  effect  and has a  sufficient  supply of
finished  thymosin alpha l for the near term and is currently  negotiating a new
vialing and packaging supply agreement. No assurances can be given that such new
agreement  will be  reached.  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.
Such interruptions could also delay  commercialization of the Company's products
and impair  their  competitive  position,  which  would have a material  adverse
effect on the business and financial condition of the Company.  See "Business --
Manufacturing."
    

      Marketing and Sales. The Company has established distribution arrangements
with local pharmaceutical  distribution companies in over 25 countries, in Asia,
Latin America and the Middle East.  However,  no assurance can be given that any
such distribution  arrangements  will remain in place or prove  successful.  See
"Business -- Marketing and Sales."

      Technological Change and Competition.  Rapid technological development may
result in the Company's  products  becoming obsolete before they are marketed or
before the Company recovers a significant portion of the related development and
commercialization  expenses.  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 U.S. 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.

      Uncertainty   of  Third   Party   Reimbursement;   Resources   of  Patient
Populations.  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 U.S.,  health
care reform is an area of increasing  national  attention and a 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 U.S. for its
products  or the  amount  of  reimbursement  for  the  Company's  products  from
governmental agencies or third party payors. 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, if at all.

      Dependence  on Qualified  Personnel  and Key  Individuals.  Because of the
specialized  scientific nature of the Company's business,  the Company is highly
dependent  upon  its  ability  to  continue  to  attract  and  retain  qualified
management, scientific and technical personnel. There is intense competition for
qualified personnel in the areas of the Company's  activities,  and there can be
no assurance that the Company will be able to continue to attract and retain the
qualified personnel necessary for the development of its business.  In addition,
many key responsibilities  within the Company have been assigned to a relatively
small number of  individuals.  Loss of the services of any of these  individuals
unless they were promptly  replaced  could be  significantly  detrimental to the
Company's  development.  The Company does not maintain key person life insurance
on the lives of any of its key personnel.

      Product  Liability;  Absence of  Insurance.  The  Company's  business will
expose  it to  potential  product  liability  risks  which are  inherent  in the
testing, manufacturing, marketing and sale of pharmaceutical products, and there
can be no assurance that product  liability  claims will not be asserted against
the  Company.  Product  liability  insurance  for  the  pharmaceutical  industry
generally  is  expensive  to the extent that it is available at all. The Company
has product  liability  insurance  coverage for clinical  trials and  commercial
sales.  However,  there can be no assurance that a product liability claim would
not adversely affect the business or financial condition of the Company.

      Possible  Volatility of Stock Price.  The market price of the Common Stock
has in the past and may in the future  fluctuate over a wide range. In addition,
the stock market has from time to time experienced  significant price and volume
fluctuations  that may be unrelated to the operating  performance  of particular
companies.  The  market  prices  of the  common  stock of many  publicly  traded
biotechnology  companies have in the past been, and can in the future be, highly
volatile.  Progress in clinical  trials by the  Company,  its  partners,  or its
competitors,   announcements  of  technological  innovations  or  new  products,
developments   or  disputes   concerning   patents  or  proprietary   rights  or
collaborative agreements,  availability of supply, publicity regarding actual or
potential  medical results relating to products under development by the Company
or its  competitors,  regulatory  developments  in both  the  U.S.  and  foreign
countries,  public  concern as to the safety of the  biotechnology  products and
economic  and  other  external  factors,  period-to-period  fluctuations  in the
Company's  financial  results,  as well as any shortfalls in revenue or earnings
from levels expected by securities  analysts,  among other factors,  have in the
past and may have in the future a significant  impact on the market price of the
Common Stock.

      Control by Existing  Shareholder.  As of  September  30, 1997, a principal
shareholder  of  the  Company  beneficially  owned  approximately  19.2%  of the
outstanding  shares of  Common  Stock.  This  shareholder  may have  significant
influence  over  all  matters  requiring  approval  by the  shareholders  of the
Company,  and will have the ability to elect a member of the Board of Directors.
Further,  any  significant  sale of shares by such  shareholder  could adversely
affect the market price of the Common Stock. However, the Company has the option
to cancel up to that number of Pledged  Shares  necessary to completely  satisfy
the outstanding balance, as of the date of this Prospectus,  of the Shareholders
Loan,  including accrued interest,  made by the Company to such shareholder in a
non-cash  exchange.  If the  Company  elects  to  exercise  this  option in full
immediately  prior to the closing of this  offering,  1,547,157  Pledged  Shares
(based on an assumed price of $5.03 less permitted discounts) would be canceled,
thereby reducing such shareholder's  beneficial  ownership to 10.2%, as adjusted
to reflect the sale of the Shares in this offering. See "Recent Developments."

      Dilution.  Purchasers  of the  Common  Stock  offered  hereby  will  incur
immediate and  substantial  net tangible book value dilution of $3.66 per share,
and, to the extent  outstanding  options and warrants to purchase the  Company's
Common Stock are exercised, there will be further dilution. See "Dilution."
    
      Blank Check  Preferred  Stock.  The  Company's  Board of Directors has the
authority  to  issue  Preferred  Stock  and  to  determine  the  price,  rights,
preferences,  privileges and restrictions,  including voting rights, without any
further vote or action by the Company's shareholders.  The rights of the holders
of the Common  Stock will be subject to, and may be  adversely  affected by, the
rights of the holders of any  Preferred  Stock that may be issued in the future.
The  issuance of Preferred  Stock,  while  providing  desirable  flexibility  in
connection with possible  acquisitions and other corporate purposes,  could have
the effect of making it more  difficult  for a third party to acquire a majority
of the outstanding voting stock of the Company. The Company has no current plans
to issue shares of Preferred Stock.

                                 USE OF PROCEEDS


      The net proceeds to the Company from the sale of the Shares offered hereby
are estimated to be  approximately  $6.8 million  assuming the sale of 1,500,000
Shares at an assumed price of $5.03 per share, the last sale price of the Common
Stock as reported by the Nasdaq  National Market on November 10, 1997, and after
deducting the Placement Agent's fee and estimated expenses of the offering.  The
Company  currently  intends to use the net  proceeds  from the  offering for the
continued development of ZADAXIN and CPX. See "Business--ZADAXIN  thymosin alpha
1" and  "--CPX."  Pending  such  uses,  the net  proceeds  will be  invested  in
short-term, interest bearing investment grade securities.
    

      Based on its current operating plan, the Company  anticipates that the net
proceeds  of this  offering,  together  with the  Company's  available  cash and
expected interest income thereon,  should be sufficient to finance the Company's
current  research and development and other working capital  requirements  until
mid-1999.  This  estimate  is  based  on  certain  assumptions  which  could  be
negatively impacted by the matters discussed in "Risk Factors."

                                    DILUTION

      The   Company's  net  tangible  book  value  at  September  30,  1997  was
approximately  $18,607,537 or $1.09 per share. Net tangible book value per share
represents the amount of the Company's  shareholders'  equity,  less  intangible
assets, divided by 17,039,486,  the number of shares of Common Stock outstanding
as of September 30, 1997.
<TABLE>

      After  giving  effect  to the sale of the  Shares in this  offering  at an
assumed  price of $5.03 per share,  the last sale  price of the Common  Stock as
reported by the Nasdaq National Market on November 10, 1997, and after deducting
commissions  and estimated  offering  expenses  payable by the Company,  the net
tangible  book value of the  Company as of  September  30,  1997 would have been
$25,401,131,  or $1.37 per share.  This represents an immediate  increase in net
tangible book value of $0.28 per share to existing shareholders and an immediate

</TABLE>

         The foregoing  table  excludes  options and warrants  outstanding as of
September  30, 1997 to purchase  3,109,236  shares of Common Stock at a weighted
average  exercise  price of $5.76 per  share.  In the  event  such  options  and
warrants are exercised, investors may experience further dilution.

         Pursuant to a July 1997  agreement  between the Company and a principal
shareholder of the Company,  such shareholder pledged 1,882,500 shares of Common
Stock as security for the Shareholder  Loan which has been recorded as an offset
to  shareholders'  equity  at  September  30,  1997.  Immediately  prior  to the
consummation  of any  offering,  the  Company  may  elect to  cancel,  through a
non-cash  exchange,  a number of the  Pledged  Shares  in  partial  or  complete
satisfaction of the Shareholder Loan, including accrued interest.  The number of
the Pledged  Shares to be so canceled  would be  determined  by reference to the
price of the shares to be sold in such offering less permitted discounts. If the
Company elects to exercise such option, immediately prior to the closing of this
offering,  in full  satisfaction  of the Shareholder  Loan and accrued  interest
then,  assuming price of $5.03 per share less permitted  discounts,  the Company
would cancel 1,547,157 of the Pledged Shares,  and the dilution per share to new
investors would be $3.54. See "Recent Developments."

                                    BUSINESS

Overview

      The Company is an emerging pharmaceutical company that acquires, develops,
and commercializes  specialist-oriented  (e.g.,  hepatologists,  oncologists and
pulmonologists),  proprietary  drugs for treating  chronic and  life-threatening
diseases for which there are no adequate treatment modalities, including chronic
hepatitis B, chronic  hepatitis C, cancer,  immune  system  disorders and cystic
fibrosis.  The Company  currently  has two  products  in  clinical  development,
ZADAXIN thymosin alpha 1 and CPX, as well as several preclinical candidates.

   
      ZADAXIN, a synthetic  immunomodulator (i.e., immune system regulator),  is
the  Company's  lead product.  In the United  States and Europe,  the Company is
developing  ZADAXIN in combination  with interferon for the treatment of chronic
hepatitis C. The Company is currently exploring  collaborative  arrangements for
the  development  of ZADAXIN in these  territories.  In Japan,  the  Company has
licensed  exclusive  rights to ZADAXIN to SPKK.  SPKK has completed  phase 1 and
phase 2 clinical  studies of ZADAXIN for the  treatment of chronic  hepatitis B.
SPKK is  expected  to  commence  a pivotal  phase 3 study of  ZADAXIN in chronic
hepatitis  B in the fourth  quarter  of 1997.  In  November  1997,  the  Company
announced  that SPKK has commenced the enrollment of patients in a phase 2 study
of  thymosin  alpha 1 as a  monotherapy  for  hepatitis  C, as  required  by the
Japanese  Ministry of Health and Welfare (MOHW) for approval of the drug for the
treatment of hepatitis C. SPKK is also working to satisfy MOHW  requirements  to
begin a clinical  program to study the use of its INTRON A(R) (interferon alfa -
2b) and ZADAXIN as a  combination  therapy for hepatitis C. ZADAXIN is currently
approved and being marketed for chronic  hepatitis B in China,  the  Philippines
and Singapore. Furthermore, the Company has filed for approval to market ZADAXIN
for this  indication in 14 additional  countries in Asia,  Latin America and the
Middle East.  SciClone  licensed thymosin alpha 1 from Alpha 1 and has worldwide
marketing,  development  and  manufacturing  rights with the exception of Japan,
Italy, Spain and Portugal, where rights have been sublicensed. Chronic hepatitis
B is the second most common  chronic  infectious  disease  worldwide.  The World
Health  Organization   estimates  that  approximately  350  million  individuals
worldwide,  or 5% of the world's  population,  are  carriers  of the virus,  the
majority of whom are located in Asia.

      CPX, the Company's  second product in clinical  development,  is an orally
administered  synthetic compound  discovered by the NIH as a potential treatment
for  CF.  CF is  caused  by a  mutation  in the  CFTR  gene.  CPX  is an  orally
administered compound that targets the biochemical abnormality at the root cause
of CF, the malfunctioning CFTR protein. In vitro studies from the NIH have shown
that CPX binds to the CFTR and permits the CFTR to enhance  the  performance  of
its chloride  secretion  function.  In October 1997,  Dr. Harvey  Pollard of the
Uniform  Services  University  of  Health  Services  and  formerly  of the  NIH,
presented  preclinical  data  demonstrating  that  CPX is the  only  CF  drug in
clinical development that can correct the two fundamental problems caused by the
most common genetic  defect in CF patients,  abnormal  trafficking  and impaired
chloride ion transport. The Company obtained orphan drug status for CPX from the
FDA in April  1997 and was  awarded a phase 1 Orphan  Drug Grant from the FDA in
October 1997. The Company is currently conducting a multicenter phase 1 clinical
study in the U.S. involving patients with CF. SciClone's phase 1 program for CPX
is the first to attempt to measure both sweat chloride and NEPD in a multicenter
trial. The Cystic Fibrosis Foundation  supported SciClone in its IND filing with
the FDA to gain  approval  to begin the  testing of CPX  directly in CF patients
rather than the normal process of testing first in healthy, normal volunteers.
    

      The Company  has  additional  compounds  under  license.  During the first
quarter of 1998, the Company plans to commence preclinical development of one of
these compounds.  Targeted indications for this compound include epilepsy, to be
studied at the NIH, and multiple drug resistance in cancer, to be studied at the
U.S. National Cancer  Institute.  The Company also plans to evaluate activity of
certain of its other preclinical candidates in 1998.

      Internationally,  SciClone has entered into over 25 exclusive distribution
arrangements to register and market ZADAXIN.  The Company intends to out-license
its products  where a  collaborative  arrangement  will  materially  enhance the
prospects for a drug's  commercial  success,  such as the Company's license with
SPKK for exclusive rights to develop and market ZADAXIN in Japan. The Company is
currently  seeking a  collaborative  arrangement  in the U.S. and Europe for the
phase 3 development  of ZADAXIN in chronic  hepatitis C. The Company  intends to
source ZADAXIN,  CPX and any future products through contract  manufacturing and
supply  agreements.  The Company has entered into supply  agreements in the U.S.
and Europe for the supply of bulk and  finished  product  thymosin  alpha 1. The
Company  currently  contracts with a major U.S.  pharmaceutical  company for the
supply  of  bulk  CPX  and  another  U.S.  pharmaceutical  manufacturer  for the
finishing of CPX.

Strategy

      SciClone's  corporate  objective is to become a leader in the acquisition,
development and commercialization of  specialist-oriented  proprietary drugs for
the treatment of chronic and life threatening  diseases.  The Company's strategy
to achieve this objective is as follows:

      Expand  Product  Pipeline.  The  Company  focuses  its  resources  on  the
development  and  commercialization  of  drugs;  not  drug  discovery.  SciClone
evaluates new  compounds for  acquisition  or in-license  from various  sources,
including  government  agencies,  universities,   pharmaceutical  companies  and
biotechnology  companies. The Company seeks development stage compounds that are
specialist-oriented,  novel and  patented.  Management  believes  that this will
enable  the  Company  to lower  its  expected  time-to-market  and risk  profile
relative to competitors engaged in both drug discovery and development.

      Optimize Resources. The Company does not own or maintain any manufacturing
facilities for finished products or raw materials.  Instead, SciClone, using its
own manufacturing  and quality  assurance staff,  out-sources these functions to
third parties that are capable of supplying current Good Manufacturing Practices
("cGMP")  bulk product and finished  goods as needed.  Management  believes that
this  strategy  will lower the  Company's  capital  requirements  and enable the
Company to concentrate its resources on drug development.

      Capitalize  on  Commercial  Capabilities.  SciClone  is equipped to manage
clinical development, regulatory submissions and pharmaceutical marketing in the
U.S., Europe and other international  markets.  The Company plans to continue to
use these  capabilities  aggressively to commercialize new and existing products
in markets around the world.  Management believes that this strategy will enable
the Company to penetrate markets in an accelerated and profitable manner.

      Enhance Product  Portfolio Patent Position.  SciClone plans to broaden the
protection of its intellectual property and trade secrets by actively developing
and expanding  the patent  filings for method of use and  composition  of matter
patents.  Management  believes  that this  strategy  will  enable the Company to
further protect the increased use of its product portfolio.

ZADAXIN thymosin alpha 1

      ZADAXIN  thymosin  alpha 1 is a naturally  occurring 28 amino acid peptide
that is produced for therapeutic use through chemical synthesis.  Its simplified
or common  chemical  name is thymosin  alpha 1. The generic name in the U.S. for
thymosin alpha 1 is thymalfasin.  The Company believes that thymosin alpha 1 has
significant  immunomodulatory  properties.  Data  demonstrates that the drug has
raised  lymphocyte  (white  blood  cell)  counts and  enhanced  multiple  immune
response parameters in a substantial number of patients. The drug appears to act
on cells of the immune  system that have been  stimulated  by infection or other
agents.  Additionally,  the drug does not  appear to  produce  the side  effects
associated   with  other   immunomodulatory   molecules,   such  as  interferon,
particularly fever, headache, chills, fatigue, nausea and inflammation. To date,
over 1,500  patients have received  thymosin  alpha 1 with no  significant  drug
related side effects.  Based on more than 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  chronic  hepatitis  B,  chronic  hepatitis C, cancer and other immune
system diseases.

      Pursuant  to the  license  agreement  with Alpha 1, the  Company  obtained
worldwide  marketing,  development and manufacturing rights to thymosin alpha 1,
with the exception of Italy, Spain and Portugal. In April 1997, SciClone entered
into an arrangement with Alpha 1 to administer the sublicense  activities of the
Alpha 1 license for Italy, Spain and Portugal.  Under the Alpha 1 agreement, the
Company also acquired  control of Alpha 1's patent  portfolio for thymosin alpha
1.

      Chronic Hepatitis B
    

      Chronic 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 chronic hepatitis B virus, many
have  asymptomatic  or minimal  disease  with no  clinically  evident  symptoms.
Carriers of the chronic  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.

      Meta Analysis

      Meta analysis is the statistical  pooling of data derived from two or more
clinical  trials.  By using  data from two or more  studies,  the play of random
chance is reduced  and  precision  of  estimates  will  increase  as sample size
increases.  A valuable use of meta  analysis is to assess the efficacy of a drug
in the  treatment  of a  particular  disease  across many  studies.  The Company
commissioned  a meta analysis of chronic  hepatitis B randomized  and controlled
trials of ZADAXIN.  The meta  analysis  was  performed  by  MetaWorks,  Inc. and
included two U.S. trials and a Taiwan trial. A statistically significant benefit
(p=0.04) was  demonstrated in the meta analysis with a ZADAXIN overall  response
rate of 36%  compared to 19% for the control  group.  The results also showed no
indications of drug toxicity and no significant drug related side effects in the
trials.

      The Company believes ZADAXIN is an effective new therapy for the treatment
of chronic hepatitis B with a superior side effect profile and efficacy equal to
or better than interferon, the primary existing therapy for chronic hepatitis B.
ZADAXIN  has  shown in  clinical  studies  to be  statistically  significant  in
efficacy  with twice  weekly  administration  for six months.  ZADAXIN has shown
proven long term durable  efficacy at five years of patient  follow up.  ZADAXIN
has shown virtually no drug related side effects in over 1,500 patients.

      Interferon is an  immunomodulatory  protein that is produced  commercially
using  recombinant DNA technology and other  techniques.  Interferon is approved
for treatment of chronic hepatitis B in the United States and Europe, as well as
in Hong Kong,  Taiwan,  China,  Japan and other  countries.  Other  agents under
development,  but not yet registered  for the treatment of chronic  hepatitis B,
include  nucleoside analogs such as lamivudine,  famciclovir and others.  Unlike
thymosin  alpha 1, data  reported in the October 1997  supplement  to Hepatology
reflect that nucleoside  analogs are associated with rebound viral hepatitis and
viral mutation.

      Set forth  below is more  detailed  information  regarding  the  status of
development  of ZADAXIN as a therapy  for  chronic  hepatitis  B in certain  key
markets.

      China. In January 1997, the Company  launched ZADAXIN for the treatment of
chronic  hepatitis B in The  People's  Republic of China.  This  product  launch
marked the first  introduction of ZADAXIN by the Company  anywhere in the world.
The Ministry of Public Health (MOPH) approval was based on a regulatory  package
assembled  from  U.S.  and  European  data in  addition  to a  locally  required
controlled  clinical  trial to evaluate  the  efficacy  of ZADAXIN for  patients
suffering  from  chronic  hepatitis  B. Sales and  distribution  in The People's
Republic  of China are  managed by  SciClone  International  based in Hong Kong.
SciClone  International  has focused its initial  sales  efforts on the southern
province of Guangjou,  the capitol city of Beijing and Shanghai.  More than four
local  distribution  teams are used to steadily  increase  sales in China and to
place ZADAXIN on the formularies of city and provincial hospitals.

   
      Japan. In Japan,  the world's largest  hepatitis  market,  the Company has
licensed exclusive thymosin alpha 1 rights to SPKK. SPKK has completed a phase 1
single  and  multiple  dose  safety  and   pharmacokinetics   trial.   SPKK  has
successfully  completed  a dose  ranging  phase  2  safety  and  efficacy  trial
involving  approximately  60  patients.  SPKK is  expected to commence a pivotal
phase 3 study in  chronic  hepatitis  B in the fourth  quarter of 1997.  Certain
costs of these  clinical  studies  will be shared by the  Company  and SPKK.  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

                                       19
<PAGE>

funds to develop and  commercialize  ZADAXIN in Japan.  Upon  approval in Japan,
SPKK is obligated  to purchase  thymosin  alpha 1 from the Company.  The Company
agreed to provide certain funding for development expenses.

      Taiwan.  The  Company has  completed  the Plant  Master  File  required by
Taiwanese law. This file will complement existing regulatory documents and allow
the Company to file for registration in Taiwan.  The Company sponsored a phase 3
chronic  hepatitis  B trial of ZADAXIN in Taiwan.  The  audited  results of this
trial showed 37% of patients responded to ZADAXIN,  compared to 25% for patients
taking a placebo.  The Company  believes this trial produced the best results of
any randomized and controlled  chronic hepatitis B trial in Taiwan.  The Company
knows of no  randomized  and  controlled  chronic  hepatitis  B  clinical  trial
conducted in Taiwan,  including  SciClone's trial,  using medically accepted end
points of both hepatitis B virus DNA and hepatitis B e-antigen  negativity  that
has produced  statistically  significant  results,  including clinical trials of
alpha  interferon,  the leading chronic  hepatitis B therapy approved in Taiwan.
The results also showed no indications of drug toxicity and no significant  drug
related side effects in the trial.
    

      Chronic Hepatitis C

      The Centers for Disease Control  estimate that 3.9 million  Americans were
infected with the chronic  hepatitis C virus,  and the American Liver Foundation
estimates  that an  additional  170,000 new cases are  reported  each year.  The
prevalence  of  chronic  hepatitis  C in  Europe  is  approximately  4  million.
Interferon is the only current  effective therapy approved for chronic hepatitis
C. The prevalence of chronic  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.  Chronic  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  chronic
hepatitis C carriers may develop  cirrhosis,  and up to 40% of these individuals
may develop liver cancer.

   
      Phase 3 Chronic Hepatitis C Combination Trial (United States).  In 1996, a
randomized,  placebo-controlled,  multicenter  study in chronic  hepatitis C was
completed.  The  trial  compared  thymosin  alpha  1  and  alpha  interferon  2b
combination treatment to alpha interferon 2b alone or a placebo. The primary end
point  of  the  trial  was  normalization  of  alanine   transaminase  (ALT),  a
measurement of liver inflammation,  and secondary end points were improvement in
liver  histology,  the  condition  of the cellular  structure of the liver,  and
reduction  in  hepatitis  C serum viral RNA (HCV RNA) viral  titer  levels,  the
amount of virus in the  blood.  The  thymosin  alpha 1 and alpha  interferon  2b
combination treatment had a statistically significant (p=0.022) improvement over
alpha interferon 2b alone.
    

      A complete  response was defined as a normal ALT level present on the last
two study visits while a partial  response was defined as a 50% decrease in ALT.
Based  on 103  patients  who  completed  the  six-month  treatment  period,  the
combination  group showed a  statistically  significant  greater  partial and/or
complete response (41.9%) as compared to alpha interferon 2b alone (16.6%),  and
to placebo (2.7%).  Ten patients who did not respond to alpha  interferon  alone
were subsequently treated for six months with the combination  regimen.  Four of
the 10 (40%) showed normalization of ALT levels after the six-month  retreatment
period.  The histologic data showed that only combination  therapy  demonstrated
statistically  significant  higher efficacy than placebo at reducing  histologic
activity.  Patients  treated  with  combination  therapy  were the only group to
achieve  significant  reduction in HCV RNA viral titer  levels in contrast  with
patients treated with single-agent  alpha interferon 2b or placebo who failed to
show a significant reduction in viral titer levels.

      Thymosin  alpha 1  Combination  Therapy with Alpha  Interferon  in Chronic
Hepatitis C Phase 2 Combination  Trial (Italy).  A 15 patient,  12 month chronic
hepatitis C  open-label  study was  completed  in Italy using a  combination  of
thymosin  alpha  1 and  lymphoblastoid  interferon.  Sustained  response  to the
combination therapy after 12 months of therapy and six months of observation was
40%  (6/15)  with  loss of  serum  HCV RNA.  This is  dramatically  higher  than
historical sustained response levels to monotherapy interferons.

      Patients were treated with the  combination  for one year and followed for
an  additional  six months after  conclusion  of  treatment.  Of the 15 patients
entered into the study,  four had previously  failed  standard alpha  interferon
therapy.  Thirteen of the 15 patients  were of genotype 1b, the  genotype  least
responsive to interferon  therapy.  At the end of treatment,  11 (73%) patients,
including two previous alpha  interferon  failures,  were negative for serum HCV
RNA measured by polymerase chain reaction (PCR). Of the 13 genotype lb patients,
nine (69%)  responded to therapy and five

                                       20

<PAGE>


of these 13  patients  (39%)  were still  negative  for serum HCV RNA six months
after treatment  ended. The overall  sustained  response after 18 months was 40%
(6/15) with loss of serum HCV RNA.  Five of these six HCV RNA negative  patients
also had normalization of ALT levels.  Histological  improvement was observed in
the post-treatment liver biopsy specimens of 12 patients for whom paired samples
were available

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

   
      Japan.  In Japan,  the world's  largest  hepatitis  market,  SciClone  has
licensed  exclusive  thymosin  alpha 1 rights to SPKK.  In  November  1997,  the
Company  announced that SPKK has commenced the enrollment of patients in a phase
2 study of thymosin alpha 1 as a monotherapy for hepatitis C, as required by the
Japanese  Ministry of Health and Welfare (MOHW) for approval of the drug for the
treatment of hepatitis C. SPKK is also working to satisfy MOHW  requirements  to
begin a clinical  program to study the use of its INTRON A(R) (interferon alfa -
2b) and ZADAXIN as a combination therapy for hepatitis C.
    

      U.S./Europe.  In the United  States and Europe,  the Company is developing
ZADAXIN in combination with interferon for the treatment of chronic hepatitis C.
After  meeting with U.S. and European  regulatory  authorities,  the Company has
prepared a protocol outline for the required pivotal phase 3 chronic hepatitis C
studies,   which  has  been   refined   with   several   leading   international
hepatologists. The Company is currently exploring collaborative arrangements for
the development of ZADAXIN in these territories.

CPX

   
      Cystic Fibrosis.  CF is the most common fatal genetic disorder in the U.S.
today. CF affects approximately 30,000 children and young adults in the U.S. and
approximately  25,000 in Europe.  In the U.S., CF occurs in approximately one of
every 3,300 live births and  approximately  1,000 new cases are  diagnosed  each
year,  usually by the age of three. The median age of survival for a person with
CF is 31 years.  CF is caused by a mutation in the CFTR gene. This basic genetic
defect in CF cells results in the faulty transport of chloride and sodium (salt)
within  epithelial  cells (which line organs such as the lungs and  pancreas) to
the cells' outer surfaces.  This faulty  transport causes the body to produce an
abnormally  thick,  sticky  mucus  which  clogs  the  lungs  and  leads to fatal
infections.  This thick,  sticky mucus also  obstructs the pancreas,  preventing
enzymes from reaching the  intestines to digest food.  Most CF patients die from
lung disease. One in 29 Americans, more than 10 million people, is an unknowing,
symptomless  carrier of the  defective  gene. A child must inherit two defective
copies of the CF gene, one from each parent,  to have CF. Each time two carriers
conceive  a child,  there is a 25%  chance  that the  child  will have CF, a 50%
chance that the child will be a carrier, and a 25% chance that the child will be
a non-carrier.

      CF has a variety of  symptoms.  The most  common are:  very  salty-tasting
skin;  persistent coughing,  wheezing or pneumonia;  excessive appetite but poor
weight gain; and bulky, foul-smelling stools. Currently, approved treatments for
CF  only  address  the  symptoms  of  CF  and  not  the  underlying  biochemical
abnormality  at the  root  cause  of the  disease  that  results  in the  faulty
transport  of chloride  and sodium  across  epithelial  cells and to their outer
surfaces.  The  treatment  of CF depends upon the stage of the disease and which
organs are involved.  One means of  treatment,  postural  drainage  (also called
chest physical therapy), requires vigorous percussion (by using cupped hands) on
the  back and  chest  to  dislodge  the  thick,  sticky  mucus  from the  lungs.
Antibiotics  are  also  used to  treat  lung  infections  and  are  administered
intravenously,  orally  and/or in medicated  vapors which are inhaled to open up
clogged airways. In addition,  mucolytic (mucus-thinning) drugs are also used to
thin the viscosity of the mucus. When CF affects the digestive system,  the body
does not absorb enough nutrients.  Therefore,  people with CF may need to eat an
enriched diet and take both replacement vitamins and enzymes. The annual average
cost  of  care  of a CF  patient  has  been  estimated  by the  Cystic  Fibrosis
Foundation to be approximately $50,000 per patient.

      CPX. CPX is an orally available  xanthine  derivative that is produced for
therapeutic  use  through  chemical  synthesis.   CPX  targets  the  biochemical
abnormality  at the root  cause of CF,  the  malfunctioning  CFTR  protein  that
results in the buildup of thick,  sticky mucus.  CPX use in CF was discovered by
Harvey Pollard, M.D., Ph.D., and Kenneth Jacobson,  Ph.D., while at the National
Institute of Diabetes and  Digestive  and Kidney  Disorders  (NIDDK) of the NIH.

                                       21

Previous NIH  preclinical  data indicated  that CPX interacts  directly with the
malfunctioning CFTR protein to enhance the performance of its chloride secretion
function.  Thus,  the Company  believes CPX could  prevent the buildup of thick,
sticky mucus and become a unique  therapy  correcting  the protein  defect,  the
malfunctioning CFTR, in all organs affected by CF.

      Consistent with the Company's strategy, SciClone licensed CPX from the NIH
in April 1996.  In January  1997,  the  Company's IND was approved by the FDA to
begin clinical  studies of CPX in the U.S.  directly in CF patients  rather than
normal, healthy volunteers. The Cystic Fibrosis Foundation supported SciClone in
its IND filing with the FDA to gain approval to begin testing of CPX directly in
patients.  In April 1997, the Company  obtained  orphan drug status for CPX from
the FDA. In May 1997, the Company  initiated a multicenter  phase 1 trial of CPX
directly in CF patients.  In October 1997,  the FDA awarded  SciClone a $100,000
Orphan  Drug  Grant for phase 1  development  of CPX as a  treatment  for CF. In
October 1997, Dr. Harvey Pollard presented  preclinical data  demonstrating that
CPX is the  only  CF drug in  clinical  development  that  can  correct  the two
fundamental  problems  caused by the most common  genetic defect in CF patients,
abnormal trafficking and impaired chloride ion transport.  Trafficking refers to
the ability of the CFTR  protein to traverse  the cell  cytoplasm  and reach the
proper location on the cell membrane.
    

      Phase 1 CPX trial in CF Patients (United States). The Company is currently
conducting  its phase 1 clinical study of CPX at five CF centers in the U.S. The
five  participating  CF  centers  are:  Stanford  CF  Center,   Lucille  Packard
Children's  Hospital in Palo Alto,  California;  University  of  Washington  and
Children's  Hospital  CF  Center  in  Seattle,  Washington;  University  of Iowa
Hospitals  and  Clinics  CF Center in Iowa City,  Iowa;  The LeRoy  Matthews  CF
Center, Rainbow Babies and Children's Hospital in Cleveland, Ohio; and The Emory
University CF Center,  Egleston  Children's  Hospital in Atlanta,  Georgia.  The
study is evaluating the safety and  pharmacokinetic  profile of CPX, that is its
ability to be orally absorbed,  determining the best dose to use and determining
how  often it  should  be taken.  In  addition,  the study is the first  ever to
attempt to measure both sweat  chloride and NEPD in a multicenter  trial.  Sweat
chloride  and NEPD are  surrogate  markers of  efficacy  and are  abnormal in CF
patients. The phase 1 trial may provide an early indication of CPX effectiveness
if it demonstrates improvement of sweat chloride and NEPD tests.

Marketing and Sales

   
      In general,  the Company plans to market and sell its products in the U.S.
by establishing its own marketing and sales  organization.  Outside of the U.S.,
the  Company   currently   plans  to  market  and  sell  its  products   through
collaborative or distribution  arrangements,  which may include co-marketing and
sales agreements.

      In the U.S., CPX is still in clinical development.  Currently, the Company
plans to market and sell CPX in the U.S.  through the  establishment  of its own
marketing and sales organization. In Europe, the Company is evaluating its plans
for marketing and selling CPX.
    

      In the U.S. and Europe, thymosin alpha 1 is still in clinical development.
In Europe,  SciClone is currently exploring various  collaborative  arrangements
with major  pharmaceutical  companies for the development of thymosin alpha 1 in
combination  with  interferon  for the  treatment  of chronic  hepatitis C. Such
collaborative  arrangements may include marketing and sales cooperation.  In the
U.S., the Company may consider collaborative arrangements for ZADAXIN.

   
     SciClone's  non-U.S./non-European  thymosin  alpha 1  marketing  and  sales
strategy,  apart from Japan, is to establish its own proprietary  regional sales
and marketing  capabilities to  commercialize  thymosin alpha 1. Consistent with
this strategy, SciClone focuses on educating the medical opinion leaders in each
country and targeting the leading  specialists and teaching  hospitals,  tactics
consistent  with the successful  introduction of  specialist-oriented  medicines
targeted at patients who have the ability to purchase them. SciClone manages the
intellectual  processes  of  marketing,  medical  education  and the  running of
clinical trial and clinical  experience  programs.  Distributors assist SciClone
with local regulatory submissions to the ministries of health as well as import,
inventory,  physically distribute and invoice ZADAXIN. SciClone International is
based in Hong Kong and has international offices in Singapore, Taiwan and Japan.
SciClone  International also manages a distribution center in Hong Kong which is
the source for all  ZADAXIN  exported  to the  non-U.S.  markets.  SciClone  has
established  distribution  arrangements with local  pharmaceutical  distribution


                                       22

<PAGE>

companies in over 25  countries  outside of the U.S.,  Europe and Japan.  In its
three approved Asian ZADAXIN  markets  (China,  the  Philippines and Singapore),
SciClone has  established  a marketing  program  including the  positioning  and
pricing of the drug. Local sales are managed by dedicated  distributor employees
nominated and supported by SciClone. In Japan, as previously discussed, SciClone
has licensed SPKK to develop and market thymosin alpha 1.
    

Manufacturing

      The Company has entered into contract  manufacturing and supply agreements
to source  ZADAXIN and CPX.  SciClone has a European cGMP third party source for
bulk thymosin  alpha 1 peptide for the European,  Asian (except  Japan),  Middle
Eastern and Latin  American  markets.  This bulk peptide is turned into finished
sterile injectable form by a separate European cGMP manufacturer.  This finished
product is shipped to Hong Kong for labeling and redistribution  worldwide.  For
the  U.S.  and  Japanese   markets,   an  alternative  U.S.  located  cGMP  bulk
manufacturer  and  a  separate  cGMP  finishing  plant  are  utilized.   CPX  is
manufactured for SciClone in the U.S. by a major U.S. pharmaceutical company and
turned into finished form by a separate U.S.  pharmaceutical  manufacturer.  The
Company  directly  monitors  production runs of its products and manages its own
Quality Assurance programs. The Company is constantly managing the manufacturing
processes and participating in production and quality testing upgrades. SciClone
has established an inventory sufficient to fulfill its expected  requirements in
the near term.

Patents and Proprietary Rights

      The Company is the exclusive  licensee of composition  of matter,  process
and use  patents and pending  applications  related to thymosin  alpha 1, in the
U.S. and abroad.

   
      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.  Certain of these foreign composition of matter patents expired
in October 1997.  However,  the Company is the exclusive licensee of a number of
composition  of  matter  patents  and  applications   directed  to  analogs  and
derivatives of thymosin alpha 1. The Company is also the exclusive  licensee and
is directing  prosecution  of use and process  patents  related to the method of
making and  therapeutic  uses of thymosin alpha 1. Consistent with its strategy,
the Company also has filed its own use patents for thymosin alpha 1.
    

      Process patents owned by Alpha 1 and exclusively  licensed to SciClone are
directed to methods of making  thymosin  alpha 1 and have issued in the U.S.,  a
majority of European countries, Hong Kong and Taiwan.

      SciClone also has exclusively  licensed  patents and pending  applications
covering  numerous  uses of thymosin  alpha 1,  including  treatment  of chronic
hepatitis  C which has  issued in a  majority  of  European  countries,  Taiwan,
Australia and South Africa. Patents under which SciClone is exclusively licensed
have additionally  issued in the U.S. and Australia covering the use of thymosin
alpha 1 to treat small cell and non-small cell lung cancer;  in the U.S.,  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 the U.S., Taiwan and South Africa covering the use of thymosin alpha
1 to treat septic  shock;  and in the U.S.,  Australia,  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  chronic  hepatitis  B
carriers  with  minimal  disease.   Numerous  corresponding   additional  patent
applications  in  other  countries  are  pending  for  each of the  above  named
indications.

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

      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 thymosin alpha 1 is

                                       23

<PAGE>

being  accomplished  through a worldwide  filing of trademark  applications  for
ZADAXIN and other  trademarks  which appear on the  commercial  packaging of the
product and are 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 has also implemented  anti-counterfeiting  measures on
commercial   packaging  and  plans  to  register  the  packaging   with  customs
departments in countries where such procedures exist.

      The  Company  is  pursuing  similar  types of  protection  for CPX,  where
applicable.  The Company is the holder of an orphan drug product designation for
CPX to treat CF in the U.S.

      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.

                               RECENT DEVELOPMENTS

   
      On July 23, 1997,  Thomas E. Moore,  then Chairman of the Board and one of
the  founders  of the  Company,  pledged  1,882,500  shares of  Common  Stock as
security  for the  Shareholder  Loan  which  has been  recorded  as an offset to
shareholders'  equity at September 30, 1997. Interest on the principal amount of
the Shareholder  Loan accrues at a rate of 7% per annum and the Shareholder Loan
is  repayable in July 1999.  While the  Shareholder  Loan  remains  outstanding,
immediately  prior to the closing of any offering of the  Company's  securities,
the Company may elect to cancel,  through a non-cash  exchange,  a number of the
Pledged  Shares in partial or complete  satisfaction  of the  Shareholder  Loan,
including accrued  interest.  The number of the Pledged Shares to be so canceled
would be  determined  by reference to the price of the shares of Common Stock to
be sold in the  then-pending  offering less  permitted  discounts.  To date, the
Company has not cancelled any of the Pledged Shares.  If,  immediately  prior to
the closing of this offering, the Company elects to exercise such option in full
satisfaction of the Shareholder Loan and accrued interest, then assuming a price
of $5.03 per share,  the last sale price of the Common  Stock as reported by the
Nasdaq  National  Market on November  10,  1997 less  permitted  discounts,  the
Company would cancel  1,547,157 of the Pledged  Shares.  Effective July 24, 1997
Mr. Moore  resigned from the Board of Directors to pursue other  interests.  See
"Management."

requested and no investor funds will be accepted  until  indications of interest
have  been  received  for  all  of  the  Shares.  Confirmations  and  definitive
prospectuses  will be  distributed  to all  investors  at the  time of  pricing,
informing  investors  of the closing  date,  which will be  scheduled  for three
business  days  after  pricing.  No  investor  funds will be  accepted  prior to
effectiveness of the Registration Statement. After the Registration Statement is
declared  effective  and prior to the closing date,  all investor  funds will be
placed  promptly,  and in any event no later than noon Pacific  Standard Time of
the next business day following  receipt,  in escrow with the Escrow Agent in an
escrow account  established  for the benefit of the investors.  The Escrow Agent
will invest such funds in  accordance  with Rule  15c2-4  promulgated  under the
Exchange  Act.  Prior to the  closing  date,  the Escrow  Agent will  advise the
Company  whether the investors have deposited the requisite  funds in the escrow
account at the Escrow Agent.  If the requisite  funds have been  deposited,  the
Company will deposit with The Depository Trust Company the Shares to be credited
to the  respective  accounts of the  investors.  Investor  funds,  together with
interest  thereon,  if  any,  will  be  collected  by the  Company  through  the
facilities of the Escrow Agent on the scheduled  closing date. The offering will
not continue  after the closing date.  In the event that investor  funds are not
received, all funds deposited in the escrow account will promptly be returned in
the full amount necessary to satisfy the requirements of the offering.

Item 15.      Indemnification of Directors and Officers

      The Company's Restated Articles of Incorporation, as amended, provide that
the liability of the  directors for monetary  damages shall be eliminated to the
fullest extent permissible under California law. Pursuant to California law, the
Company's  directors shall not be liable for monetary  damages for breach of the
directors' fiduciary duty of care to the Company and its shareholders.  However,
this provision in the Restated Articles of Incorporation  does not eliminate the
duty of  care,  and in  appropriate  circumstances  equitable  remedies  such as
injunctive  or other forms of  nonmonetary  relief will remain  available  under
California  law.  In  addition,  each  director  will  continue to be subject to
liability  (i) for acts or omissions  that involve  intentional  misconduct or a
knowing  and  culpable  violation  of law,  (ii)  for acts or  omissions  that a
director  believes to be contrary  to the best  interests  of the Company or its
shareholders  or that  involve  the  absence  of good  faith  on the part of the
director,  (iii) for any transaction  from which a director  derived an improper
personal benefit,  (iv) for acts or omissions that show a reckless disregard for
the director's duty to the Company or its shareholders in circumstances in which
the director  was aware,  or should have been aware,  in the ordinary  course of
performing a director's  duties,  of a risk of serious  injury to the Company or
its shareholders, (v) for acts or omissions that constitute an unexcused pattern
of  inattention  that amounts to an  abdication  of the  director's  duty to the
Company  or its  shareholders,  (vi) for any  transaction  that  constitutes  an
illegal  distribution  or  dividend  under  California  law,  and  (vii) for any
transaction  involving an unlawful conflict of interest between the director and
the  Company  under  California  law.  The  provision  also  does  not  affect a
director's  responsibilities under any other law, such as the federal securities
laws or state or federal environmental laws.

      In addition, the Company's Restated Articles of Incorporation, as amended,
provide that the Company is authorized to provide  indemnification of agents (as
defined  under  California  law)  for  breach  of  duty to the  Company  and its
shareholders  through  bylaw  provisions,  agreements  with the agents,  vote of
shareholders  or  disinterested   directors  or  otherwise,  in  excess  of  the
indemnification  otherwise permitted by California law, subject to the limits on
such excess indemnification set forth in California law.

      The Company's Bylaws provide that the Company will indemnify its directors
and officers to the maximum extent and in the manner permitted by California law
and may indemnify  its  employees and other agents to the maximum  extent and in
the manner  permitted by  California  law. Such  indemnification  is intended to
provide the

                                      II-1

<PAGE>

full  flexibility   available  under  California  law  and  may,  under  certain
circumstances,  include  indemnification  for negligence,  gross  negligence and
certain types of recklessness.  Under  California law and the Company's  Bylaws,
the Company will be permitted to indemnify its  directors,  officers,  employees
and other  agents,  within the  limits  established  by law and  public  policy,
pursuant to an express contract, bylaw provision, shareholder vote or otherwise,
any or all of which could  provide  indemnification  rights  broader  than those
expressly   available  under  California  law.  The  Company  has  entered  into
agreements with its directors and certain of its officers,  including all of its
executive  officers,  that require the Company to indemnify such persons against
expenses,   judgments,   fines,  settlements  and  other  amounts  actually  and
reasonably  incurred  (including  expenses of a derivative action) in connection
with any proceeding,  whether actual or threatened, to which any such person may
be made a party by reason of the fact that such  person is or was a director  or
an officer of the Company or any of its  affiliated  enterprises,  provided such
person acted in good faith and in a manner such person reasonably believed to be
in or not opposed to the best  interests of the Company and, with respect to any
criminal  proceeding,  had no reasonable cause to believe his or her conduct was
unlawful. The indemnification  agreements also set forth certain procedures that
will apply in the event of a claim for indemnification thereunder.

      The form of  Placement  Agent  Agreement  filed as Exhibit 1.1 hereto sets
forth  certain  provisions  with  respect  to  the  indemnification  of  certain
controlling   persons,   directors  and  officers  against  certain  losses  and
liabilities, including certain liabilities under the Securities Act.

Item 16.      Exhibits

      See Exhibit Index.

Item 17.      Undertakings

      Insofar as  indemnification  for liabilities  arising under the Securities
Act of 1933 may be permitted to directors,  officers and controlling  persons of
the  Registrant,  pursuant  to  the  foregoing  provisions,  or  otherwise,  the
Registrant  has been advised that in the opinion of the  Securities and Exchange
Commission  such  indemnification  is against  public policy as expressed in the
Securities Act and is, therefore,  unenforceable.  In the event that a claim for
indemnification  against  such  liabilities  (other  than  the  payment  by  the
Registrant of expenses  incurred or paid by a director,  officer or  controlling
person of the  Registrant  in the  successful  defense  of any  action,  suit or
proceeding)  is  asserted by such  director,  officer or  controlling  person in
connection with the securities being registered,  the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit  to a  court  of  appropriate  jurisdiction  the  question  whether  such
indemnification  by it is against  public policy as expressed in the  Securities
Act and will be governed by the final adjudication of such issue.

      The undersigned Registrant undertakes that:

      (1) For purposes of determining  any liability under the Securities act of
1933, the information  omitted from the form of prospectus filed as part of this
registration  statement in reliance  upon Rule 4340A and  contained in a form of
prospectus  filed by the Registrant  pursuant to Rule 424(b)(1) of (4) or 497(h)
under  the  Securities  Act  shall  be  deemed  to be part of this  registration
statement as of the time it was declared effective; and

      (2) For the purpose of determining any liability under the Securities Act,
each post-effective amendment that contains a form of prospectus shall be deemed
to be a new registration  statement  relating to the securities offered therein,
and the  offering  of such  securities  at that  time  shall be deemed to be the
initial bona fide offering thereof.

      The  undersigned  Registrant  hereby  undertakes  that,  for  purposes  of
determining  any  liability  under  the  Securities  Act,  each  filing  of  the
Registrant's  annual  report  pursuant to Section  13(a) or Section 15(d) of the
Securities  Exchange  Act of  1934  that is  incorporated  by  reference  in the
registration  statement  shall  be  deemed  to be a new  registration  statement
relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

EVEREN SECURITIES, INC.
77 West Wacker Drive
Chicago, Illinois  60601-1994
as Placement Agent

Dear Sir or Madam:

                  SciClone Pharmaceuticals,  Inc., a California corporation (the
"Company"), proposes to issue and sell 1,500,000 shares (the "Shares") of common
stock, no par value (the "Common Stock"),  to certain  investors  (collectively,
the "Investors").  The Company desires to engage you as its exclusive  placement
agent (the  "Placement  Agent") in connection  with such issuance and sale.  The
Common  Stock  is  more  fully  described  in  the  Registration  Statement  (as
hereinafter defined).

                  The Company hereby confirms as follows its agreements with the
Placement Agent.

                  1.  Agreement to Act as Placement  Agent.  On the basis of the
representations,  warranties and agreements of the Company herein  contained and
subject to all the terms and conditions of this  Agreement,  the Placement Agent
agrees to act as the Company's  exclusive placement agent in connection with the
issuance and sale, on a best efforts basis,  by the Company of the Shares to the
Investors.  The Company  shall pay to the  Placement  Agent  _____% of the gross
proceeds received by the Company from the sale of the Shares as set forth on the
cover page of the Prospectus (as hereinafter defined).

                  2. Delivery and Payment.  Concurrently  with the execution and
delivery of this Agreement, the Company, the Placement Agent and Citibank, N.A.,
as escrow  agent (the  "Escrow  Agent"),  shall  enter into an Escrow  Agreement
substantially in the form of Exhibit A attached hereto (the "Escrow Agreement"),
pursuant  to which an  escrow  account  will be  established,  at the  Company's
expense,  for the benefit of the Investors (the "Escrow Account").  Prior to the
Closing  Date (as defined  below),  (i) each of the  Investors  will  deposit an
amount 

<PAGE>

equal to the  Price to  Public  per  Share  as  shown on the  cover  page of the
Prospectus  multiplied  by the  number of Shares  purchased  by it in the Escrow
Account,  and (ii) the Escrow  Agent will notify the  Company and the  Placement
Agent in writing  whether the  Investors  have  deposited in the Escrow  Account
funds in the  amount  equal  to the  proceeds  of the sale of all of the  Shares
offered hereby (the "Requisite  Funds") into the Escrow Account.  At 10:00 a.m.,
New York City time, on _____________,  1997, or at such other time on such other
date as may be agreed  upon by the  Company  and the  Placement  Agent but in no
event prior to the date on which the Escrow Agent shall have received all of the
Requisite  Funds (such date is hereinafter  referred to as the "Closing  Date"),
the Escrow Agent will release the  Requisite  Funds from the Escrow  Account for
collection  by the  Company  and the  Placement  Agent as provided in the Escrow
Agreement  and the  Company  shall  deliver the Shares to the  Investors,  which
delivery may be made through the facilities of The Depository Trust Company. The
closing  (the  "Closing")  shall take place at the office of Stroock & Stroock &
Lavan LLP, 180 Maiden Lane, New York,  New York 10038.  All actions taken at the
Closing shall be deemed to have occurred simultaneously.

                  Certificates evidencing the Shares shall be in definitive form
and shall be registered in such names and in such denominations as the Placement
Agent  shall  request  by  written  notice to the  Company.  For the  purpose of
expediting  the  checking  and  packaging of  certificates  for the Shares,  the

                           (a)  A  registration   statement   (Registration  No.
333-______)  on  Form  S-3  relating  to the  Shares,  including  a  preliminary
prospectus  relating  to the Shares  and such  amendments  to such  registration
statement  as may have been  required  to the date of this  Agreement,  has been

amended (the "Act"), and the rules and regulations  (collectively referred to as
the "Rules and  Regulations")  of the  Securities and Exchange  Commission  (the
"Commission") thereunder, and has been filed with the Commission. The Commission
has not issued any order  preventing or suspending  the use of the Prospectus or
the Preliminary Prospectus (as defined below). The term "Preliminary Prospectus"
as  used  herein  means a  preliminary  prospectus  relating  to the  Shares  as
contemplated by Rule 430 or Rule 430A ("Rule 430A") of the Rules and Regulations
included  at any  time as part of the  registration  statement.  Copies  of such
registration statement and amendments and of each related Preliminary Prospectus
have been delivered to the Placement Agent. If such  registration  statement has
not  become  effective,  a further  amendment  to such  registration  statement,
including a form of final  prospectus,  necessary  to permit  such  registration
statement  to become  effective  will be filed  promptly by the Company with the
Commission.  If  such  registration  statement  has  become  effective,  a final
prospectus relating to the Shares containing information permitted to be omitted
at the time of  effectiveness by Rule 430A will be filed by the Company with the
Commission in accordance with Rule 424(b) of the Rules and Regulations  promptly
after  execution  and  delivery  of  this  Agreement.   The  term  "Registration
Statement" means the registration statement as amended at

                                      -2-

the time it becomes or became  effective (the "Effective  Date"),  including all
material  incorporated  by reference  therein and any  information  deemed to be
included by Rule 430A. The term  "Prospectus"  means the prospectus  relating to
the Shares as first  filed with the  Commission  pursuant  to Rule 424(b) of the
Rules and  Regulations  or, if no such  filing  is  required,  the form of final
prospectus relating to the Shares included in the Registration  Statement at the
Effective Date, in either case, including all material,  if any, incorporated by
reference therein.

                           (b) On the date that any  Preliminary  Prospectus was
filed  with the  Commission,  the date the  Prospectus  is first  filed with the
Commission pursuant to Rule 424(b) (if required), at all times subsequent to and
including  the  Closing  Date  and  when  any  post-effective  amendment  to the
Registration  Statement  becomes effective or any amendment or supplement to the
Prospectus  is filed  with the  Commission,  the  Registration  Statement,  each
Preliminary  Prospectus and the Prospectus (as amended or as supplemented if the
Company  shall  have filed  with the  Commission  any  amendment  or  supplement
thereto),  including the financial statements included in the Prospectus, did or
will  comply  with  all  applicable  provisions  of the Act and  the  Rules  and
Regulations and did or will contain all statements required to be stated therein
in accordance with the Act and the Rules and Regulations.  On the Effective Date
and when any  post-effective  amendment to the  Registration  Statement  becomes
effective,  no part of the  Registration  Statement or any such amendment did or
will contain any untrue statement of a material fact or omit to state a material
fact required to be stated  therein or necessary in order to make the statements
therein not misleading. At the Effective Date, at the date the Prospectus or any
amendment or supplement to the  Prospectus is filed with the  Commission  and at
the Closing Date the Prospectus did not or will not contain any untrue statement
of a  material  fact or omit to  state a  material  fact  necessary  to make the
statements  therein,  in the light of the  circumstances  under  which they were
made, not misleading.  The Company has not distributed any offering  material in
connection  with  the  offering  or sale of the  Common  Stock,  other  than the
Registration  Statement,  the  Preliminary  Prospectus,   the  Prospectus,   the
Company's  Annual Report on Form 10-K for the year ended  December 31, 1996 (the
"Annual  Report"),  the Company's  Quarterly Reports on Form 10-Q for the fiscal
quarters ended March 31, 1997 and June 30, 1997 (the "Quarterly  Reports"),  the
Company's  Current  Report on Form 8-K filed on October 14,  1997 (the  "Current
Report"),  the  Company's  registration  statement on Form 8-A dated January 31,

                           (c) The Company is, and at the Closing  Date will be,
a corporation  duly organized,  validly  existing and in good standing under the
laws of  California.  The Company has,  and at the Closing Date will have,  full
corporate power and authority to conduct all the activities  conducted by it, to
own or lease all the assets owned or leased by it and to conduct its business as
described in the Registration Statement and the Prospectus.  The Company is, and
at the Closing Date will be, duly  licensed or qualified to conduct its business
and in good standing as a foreign organization in all jurisdictions in which the
nature of the activities conducted by it or the character of the assets owned or
leased by it makes such  licensing  or  qualification  necessary,  except  where
failure to so license or qualify does not have a material  adverse effect on the
business, prospects,  properties,  condition (financial or

                                      -3-

otherwise),  net  worth  or  results  of  operations  of  the  Company  and  the
Subsidiaries (as defined herein),  taken as a whole. Except for the stock of the
Subsidiaries  and as disclosed in the Registration  Statement,  the Company does
not own,  and at the  Closing  Date will not own,  directly or  indirectly,  any
shares  of stock  or any  other  equity  or  long-term  debt  securities  of any
corporation or have any equity interest in any firm, partnership, joint venture,
association  or other  entity.  Complete  and correct  copies of the articles or
certificate  of  incorporation  and  of  the  bylaws  of  the  Company  and  the
Subsidiaries,  and all  amendments  thereto have been delivered to the Placement
Agent,  and no changes  therein will be made  subsequent  to the date hereof and
prior to the Closing Date.

                           (d) Each of the Company's subsidiaries (as defined in
the Act) are identified on Exhibit 23.1 of the Annual Report,  which such Annual
Report is  incorporated  by reference into the  Registration  Statement,  and is
referred to herein as a "Subsidiary"  and  collectively  as the  "Subsidiaries".
Each  Subsidiary  is, and at the Closing Date will be, duly  organized,  validly
existing and in good standing in the  jurisdiction  of its  incorporation.  Each
Subsidiary  has, and at the Closing  Date will have,  full  corporate  power and
authority to conduct all the activities conducted by it, to own or lease all the
assets  owned or leased by it and to conduct its  business as  described  in the
Registration  Statement or  Prospectus.  Each  Subsidiary is, and at the Closing
Date will be, duly  licensed or  qualified  to conduct its  business and in good
standing as a foreign  organization in all  jurisdictions in which the nature of
the activities conducted by it or the character of the assets owned or leased by
it makes such licensing or qualification  necessary,  except where failure to so
license or  qualify  does not have a material  adverse  effect on the  business,
prospects,  properties, condition (financial or otherwise), net worth or results
of operations  of the Company and the  Subsidiaries,  taken as a whole.  All the
outstanding  shares of capital stock of each of the Subsidiaries  have been duly
authorized and validly issued, are fully paid and nonassessable,  and are wholly
owned by the  Company  directly,  free and  clear of any  lien,  adverse  claim,
security  interest,  equity or other  encumbrance,  except as  described  in the
Registration Statement or Prospectus.

                           (e) The  issued  and  outstanding  shares of  capital
stock of the Company have been duly authorized,  validly issued,  are fully paid
and nonassessable  and are not subject to any preemptive or similar rights.  The
Company has an authorized,  issued and outstanding capitalization as of June 30,
1997 as set forth  under the caption  "Capitalization"  in the  Prospectus.  The
description of the securities of the Company  incorporated by reference into the
Registration  Statement and the  Prospectus is, and at the Closing Date will be,
complete and accurate in all respects.  Except as set forth in the  Registration
Statement and the  Prospectus,  and except for options to purchase shares of the
Company's Common Stock granted under the Company's stock option plans and shares
of Common Stock issued under the Company's Employee Stock Purchase Plan, neither
the Company nor the Subsidiaries  has outstanding,  and at the Closing Date will
not have  outstanding,  any  options to  purchase,  or any rights or warrants to
subscribe  for,  or  any  securities  or   obligations   convertible   into,  or
exchangeable  for, or any contracts or  commitments to issue or sell, any shares
of capital stock or other securities.

                           (f) This  Agreement  has  been  duly  authorized  and
validly executed and delivered by the Company and is a legal,  valid and binding
agreement of the Company

                                      -4-
<PAGE>

enforceable  against the Company in  accordance  with its terms,  subject to the
effect of bankruptcy,  insolvency, moratorium, fraudulent conveyance and similar
laws relating to or affecting  creditors'  rights  generally and court decisions
with respect thereto.  The Escrow Agreement has been duly authorized and validly
executed  and  delivered  by the  Company  and is a  legal,  valid  and  binding
agreement of the Company  enforceable against the Company in accordance with its
terms, subject to the effect of bankruptcy,  insolvency,  moratorium, fraudulent
conveyance and similar laws relating to or affecting creditors' rights generally
and court decisions with respect thereto.

                           (g) The  issuance  and sale of the  Shares  have been
duly  authorized  by the  Company,  and the Shares,  when issued and paid for in
accordance with this Agreement,  will be duly and validly issued, fully paid and
nonassessable  and will not be subject to  preemptive  or  similar  rights.  The
holders of the Shares  will not be subject to  personal  liability  by reason of
being such holders.  The Shares,  when issued,  will conform to the  description
thereof set forth in the Prospectus.

                           (h) The  consolidated  financial  statements  and the
related  notes and schedules  incorporated  by reference  into the  Registration
Statement and the Prospectus present fairly the consolidated financial condition
of the Company and the  Subsidiaries as of the respective  dates thereof and the
results of  operations,  shareholder's  equity  (deficit)  and cash flows at the
respective  dates  and  for  the  respective  periods  covered  thereby,  all in
conformity with generally accepted  accounting  principles ("GAAP") applied on a
consistent  basis  throughout  the entire period  involved,  except as otherwise
disclosed  therein.  No other financial  statements or schedules of the Company,
the  Subsidiaries,  or any other entity are required by the Act or the Rules and
Regulations  to be included in the  Registration  Statement  or the  Prospectus.
Ernst & Young  LLP (the  "Accountants"),  who have  reported  on such  financial
statements  and  schedules,  are  independent  accountants  with  respect to the
Company  and  the  Subsidiaries  as  required  by the  Act  and  the  Rules  and
Regulations.  Such  financial  statements  and the related  notes and  schedules
incorporated  by reference  into the  Registration  Statement and the Prospectus
have been prepared in conformity with the  requirements of the Act and the Rules
and Regulations and present fairly the information  presented  therein;  the pro
forma financial  information set forth under the headings  "Prospectus Summary -
The  Offering"  and  "Capitalization"  in the  Registration  Statement  and  the
Prospectus  (and any  amendment  or  supplement  thereto)  has been  prepared in
conformity with the applicable published rules and regulations of the Commission
with respect to pro forma financial  information,  and the  assumptions  used in
preparing  such  information  are  reasonable;   and  the  other  financial  and
statistical  information and data included in the Registration Statement and the
Prospectus  (and any amendment or supplement  thereto) are accurately  presented
and prepared on a basis consistent with such financial  statements and the books
and records of the Company and the Subsidiaries.

                           (i)  The  Company  maintains  a  system  of  internal
accounting  controls  sufficient  to  provide  reasonable   assurance  that  (i)
transactions  are executed in accordance with  management's  general or specific
authorization; (ii) transactions are recorded as necessary to permit preparation
of  financial  statements  in  conformity  with  generally  accepted  accounting

                                      -5-
<PAGE>

principles and to maintain  accountability for assets; (iii) access to assets is
permitted   only  in   accordance   with   management's   general  or   specific
authorization;  and (iv) the recorded accountability for assets is compared with
existing  assets at reasonable  intervals and  appropriate  action is taken with
respect to any differences.

                           (j)  Subsequent to the  respective  dates as of which
information is given in the Registration  Statement and the Prospectus and prior
to the Closing Date,  except as set forth in or contemplated by the Registration
Statement and the Prospectus,  (i) there has not been and will not have been any
change in the  capitalization  of the  Company  or the  Subsidiaries  other than
non-material changes in the ordinary course of business, or any material adverse
change  in  the  business,  prospects,   properties,   condition  (financial  or
otherwise),   net  worth  or  results  of  operations  of  the  Company  or  the
Subsidiaries  arising  for any  reason  whatsoever,  (ii)  the  Company  and the
Subsidiaries  have  not  incurred  nor  will  any of  them  incur  any  material
liabilities or  obligations,  direct or  contingent,  nor has the Company or the
Subsidiaries  entered  into  nor  will  any of  them  enter  into  any  material
transactions other than pursuant to this Agreement,  the Registration  Statement
and the  transactions  referred  to herein and therein and (iii) the Company has
not and will not have paid or declared any dividends or other  distributions  of
any kind on any class of its capital stock.

                           (k) Any real property and buildings  held under lease
to the  Company  or the  Subsidiaries  are held or leased by them  under  valid,
binding  and  enforceable   leases   conforming  to  the   description   thereof
incorporated  by reference into the  Registration  Statement and the Prospectus,
with such  exceptions as do not  interfere  with the use made and proposed to be
made of such property and buildings by the Company or the  Subsidiaries,  as the
case may be.

                           (l) The  Company is not an  "investment  company"  as
such term is defined in the  Investment  Company  Act of 1940,  as amended  (the
"Investment  Company  Act")  and is not  required  to be  registered  under  the
Investment Company Act.

                           (m)  Except  as  set  forth  or  referred  to in  the
Registration  Statement  and the  Prospectus,  there  are no  actions,  suits or
proceedings  pending,  or to the  Company's  knowledge,  threatened,  against or
affecting the Company or the Subsidiaries or any of their respective officers in
their  capacity as such,  before or by any Federal or state  court,  commission,
regulatory body,  administrative  agency or other governmental body, domestic or
foreign,  wherein an unfavorable  ruling,  decision or finding might  materially
adversely affect the business,  prospects,  properties,  condition (financial or
otherwise),  net  worth  or  results  of  operations  of  the  Company  and  the
Subsidiaries, taken as a whole.

                           (n) The Company and each  Subsidiary  has, and at the
Closing  Date will  have,  (i) all  governmental  licenses,  permits,  consents,
orders, approvals and other authorizations necessary to carry on its business as
contemplated  in the Prospectus  (or if the Prospectus is not in existence,  the
most recent Preliminary  Prospectus),  (ii) complied with all laws,  regulations
and orders  applicable  to either it or its  business,  where the  failure to so
comply  would  have  a  material  adverse  effect  on the  business,  prospects,
properties,  condition

agreement or instrument (collectively, a "contract or other agreement") to which
it is a party or by which its property is bound or affected, except as otherwise
set forth in the Registration Statement and the Prospectus and except where such
default would not have a material  adverse  effect on the  business,  prospects,
properties,  condition  (financial  or  otherwise),  net  worth  or  results  of
operations of the Company, and, to the Company's knowledge, no other party under
any  contract  or other  agreement  to which it is a party is in  default in any
respect thereunder. Neither the Company nor the Subsidiaries are in violation of
any provision of its organizational or governing documents.

                           (o) The Company has all corporate power and authority
to enter  into this  Agreement  and the Escrow  Agreement,  and to carry out the
provisions and conditions hereof and thereof, and all consents,  authorizations,
approvals and orders of any court,  government,  or governmental  agency or body
having jurisdiction over the Company or its properties or operations required in
connection  herewith and  therewith  have been  obtained,  except such as may be
required under state securities or Blue Sky laws or the by-laws and rules of the
National Association of Securities Dealers, Inc. (the "NASD").

                           (p) Neither (i) the  issuance,  offering  and sale of
the Shares  pursuant  hereto,  nor (ii) the  compliance  by the Company with the
other   provisions   hereof  require  the  consent,   approval,   authorization,

Sky laws or the bylaws and rules of the NASD and, if the Registration  Statement
is not effective under the Act as of the time of execution  hereof,  such as may

                           (q) Neither the  execution  of this  Agreement or the
Escrow  Agreement,  nor the  issuance,  offering or sale of the Shares,  nor the
consummation  of any of the  transactions  contemplated  herein or in the Escrow
Agreement,  nor the  compliance  by the  Company  with the terms and  provisions
hereof or thereof will conflict  with, or will result in a breach of, any of the
terms and provisions of, or has  constituted or will constitute a default under,
or has  resulted in or will result in the  creation or  imposition  of any lien,
charge  or  encumbrance  upon any  property  or  assets  of the  Company  or the
Subsidiaries  pursuant to the terms of any contract or other  agreement to which
the Company or the  Subsidiaries may be bound or to which any of the property or
assets of the  Company or the  Subsidiaries  is  subject;  nor will such  action
result in any violation of the provisions of the Company's or the  Subsidiaries'
organizational  or  governing  documents,  or any statute or any order,  rule or
regulation  applicable to the Company or the  Subsidiaries or of any court or of
any federal, state or other regulatory authority or other government body having
jurisdiction  over the Company or the  Subsidiaries,  except for such conflicts,
breaches,  defaults,  liens, charges,  encumbrances or violations which will not
have a material  adverse effect on business,  prospects,  properties,

                           (r) There is no  document  or contract of a character
required to be described in the  Registration  Statement or the Prospectus or to
be filed as an exhibit to the  Registration  Statement which is not described or
filed as required.  All such contracts to which the Company or the  Subsidiaries
is a party have been duly  authorized,  executed and delivered by the Company or
the Subsidiaries,  constitute valid and binding agreements of the Company or the
Subsidiaries, as the case may be, and are enforceable against the Company or the
Subsidiaries  in  accordance  with the terms  thereof,  subject to the effect of
applicable  bankruptcy,  insolvency or similar laws affecting  creditors' rights
generally and equitable principles of general applicability.

                           (s) No statement,  representation or warranty made by
the Company in this Agreement or made in any certificate or document required by
this Agreement or the Escrow  Agreement to be delivered to the Placement  Agent,
the Investors or the Escrow Agent was or will be, when made, inaccurate,  untrue
or incorrect in any material respect.

                           (t)  The  Company  and  its  directors,  officers  or
controlling persons have not taken, directly or indirectly, any action intended,
or which might  reasonably  be  expected,  to cause or result,  under the Act or
otherwise,  in, or which has  constituted,  stabilization or manipulation of the
price of any  security  of the Company to  facilitate  the sale or resale of the
Common Stock.

                           (u) No holder of securities of the Company has rights
to the  registration  of any securities of the Company as a result of the filing
of the Registration Statement.

                           (v) The  Common  Stock  is  currently  listed  on the

involved in any material labor dispute nor is any such dispute threatened.

                           (x) None of the Company or the Subsidiaries or any of
their  respective  employees  or agents  have made any  payment  of funds of the
Company or the Subsidiaries, or received or retained any such funds in violation
of any law, rule or regulation where such actions are of a character required to
be disclosed in the Prospectus.

                           (y) The Company maintains  insurance of the types and
in the amounts  generally deemed adequate for its business,  including,  but not
limited to, insurance covering all real and personal property owned or leased by
the Company and the Subsidiaries  against theft,  damage,  destruction,  acts of

through the Subsidiaries, has sufficient patent rights, trademarks, trade names,
copyrights,  licenses,  approvals and governmental authorizations to conduct its
business as described in the Prospectus;  except as described in the Prospectus,
the  expiration  of any patent  rights,  trademarks,  trade  names,  copyrights,
licenses,  approvals or  governmental  authorizations  would not have a material
adverse effect on the business, prospects,  properties,  condition (financial or
otherwise),  net  worth  or  results  of  operations  of  the  Company  and  the
Subsidiaries  taken as a whole; and the Company has no knowledge of any material
infringement by it of patent rights, trademark,  trade name rights,  copyrights,
licenses, trade secrets or other similar rights of others, and there is no claim
being made  against the Company or any of the  Subsidiaries  regarding  patents,
trademark, trade names, copyright,  license, trade secrecy or other infringement
which  could  have  a  material  adverse  effect  on  the  business,  prospects,
properties,  condition  (financial  or  otherwise),  net  worth  or  results  of
operations of the Company and the Subsidiaries, taken as a whole.

                           (aa) The business,  operations  and properties of the
Company and the  Subsidiaries  have been and are being  conducted in  compliance
with all applicable laws, ordinances,  rules,  regulations,  licenses,  permits,
approvals, plans, authorizations or requirements relating to occupational safety
and health, or pollution, or protection of health or the environment (including,
without  limitation,  those  relating  to  emissions,  discharges,  releases  or
threatened   releases  of  pollutants,   contaminants   or  hazardous  or  toxic

contaminants  or hazardous  or toxic  substances,  materials or wastes,  whether
solid, gaseous or liquid in nature) of any governmental department,  commission,
board,  bureau,  agency or  instrumentality  of the United States,  any state or
political subdivision thereof, or any foreign  jurisdiction,  and all applicable
judicial or administrative agency or regulatory decrees,  awards,  judgments and
orders  relating  thereto,  and neither the  Company  nor the  Subsidiaries  has
received  any notice from any  governmental  instrumentality  or any third party
alleging any  violation  thereof or  liability  thereunder  (including,  without
limitation, liability for costs of investigating or remediating sites containing
hazardous substances and/or damages to natural resources).

                           (bb)  The  information  contained  in  the  following
documents,  which are incorporated by reference into the Registration Statement,

                                   (v)  the Company's  registration statement on
                                        Form 8-A dated October 14, 1997.

                  4. Agreements of the Company. The Company covenants and agrees
with the Placement Agent as follows:

                           (a)  The  Company  will  not,  either  prior  to  the
Effective  Date or  thereafter  during  such period as the  Prospectus  would be
required by law to be  delivered  in  connection  with sales of the Shares by an
underwriter  or dealer,  file any amendment or  supplement  to the  Registration
Statement  or the  Prospectus,  unless a copy  thereof  shall  first  have  been
submitted to the Placement Agent within a reasonable period of time prior to the
filing thereof and the Placement  Agent shall not have objected  thereto in good
faith.

                           (b) The  Company  will use its best  efforts to cause
the Registration  Statement to become  effective,  and will notify the Placement
Agent  promptly,  and  will  confirm  such  advice  in  writing,  (1)  when  the
Registration   Statement  has  become  effective  and  when  any  post-effective
amendment  thereto  becomes  effective,  (2) of any request by the securities or
other governmental authority (including,  without limitation, the Commission) of
any jurisdiction for amendments or supplements to the Registration  Statement or
the  Prospectus  or for  additional  information,  (3) of  the  issuance  by any
securities or other governmental authority (including,  without limitation,  the
Commission) of any jurisdiction of any stop order  suspending the  effectiveness
of the  Registration  Statement or the  initiation of any  proceedings  for that
purpose or the threat  thereof,  (4) of the  happening  of any event  during the
period  mentioned in Section 4(a) that in the judgment of the Company  makes any
statement made in the  Registration  Statement or the Prospectus  untrue or that
requires  the  making  of any  changes  in  the  Registration  Statement  or the
Prospectus  in  order  to  make  the  statements   therein,   in  light  of  the
circumstances  in which they are made,  not misleading and (5) of receipt by the
Company  or  any  representative  or  attorney  of  the  Company  of  any  other
communication  from the securities or other governmental  authority  (including,
without limitation,  the Commission) of any jurisdiction  relating to any of the
Registration Statement, any Preliminary Prospectus or the Prospectus.  If at any
time  any  securities  or  other  governmental  authority  (including,   without
limitation, the Commission) of any jurisdiction shall issue any order suspending
the  effectiveness  of the Registration  Statement,  the Company will make every
reasonable  effort  to  obtain  the  withdrawal  of such  order at the  earliest
possible   moment.   If  the  Company  has  omitted  any  information  from  the
Registration  Statement,  pursuant to Rule 430A, it will use its best efforts to
comply with the provisions of and make all requisite filings with the Commission
pursuant  to said Rule 430A and to notify the  Placement  Agent  promptly of all
such filings.

                           (c) If, at any time when a Prospectus relating to the
Shares is required to be  delivered  under the Act, any event occurs as a result
of which the Prospectus, as then amended or supplemented, would, in the judgment
of counsel to the Company or counsel to the Placement Agent,  include any untrue
statement of a material fact or omit to state a material fact necessary in order
to make the statements  therein,  in the light of the circumstances

                                      -10-
<PAGE>

under which they were made, not misleading,  or the Registration  Statement,  as
then amended or  supplemented,  would, in the judgment of counsel to the Company
or counsel to the Placement  Agent,  include any untrue  statement of a material
fact or omit to state a material fact necessary to make the  statements  therein
not misleading,  or if for any other reason it is necessary,  in the judgment of
counsel to the Company or counsel to the Placement  Agent,  at any time to amend
or supplement  the Prospectus or the  Registration  Statement to comply with the
Act or the Rules and Regulations, the Company will promptly notify the Placement
Agent and,  subject to Section 4(a) hereof,  will promptly prepare and file with
the  Commission,  at the  Company's  expense,  an amendment to the  Registration
Statement or an amendment or  supplement  to the  Prospectus  that corrects such
statement  or  omission  or  effects  such  compliance  and will  deliver to the
Placement Agent,  without charge, such number of copies thereof as the Placement
Agent may reasonably request.  The Company consents to the use of the Prospectus
or any amendment or supplement thereto by the Placement Agent.

                           (d) The Company will furnish to the  Placement  Agent
and its counsel,  without charge,  (i) two copies of the registration  statement
described  in Section  3(a)  hereof and each  pre-effective  amendment  thereto,
including financial statements and schedules,  and all exhibits thereto and (ii)
so long as a prospectus relating to the Shares is required to be delivered under
the Act, as many copies of each Preliminary  Prospectus or the Prospectus or any
amendment or supplement thereto as the Placement Agent may reasonably request.

                           (e) The Company will comply with all the undertakings
contained in the Registration Statement.

                           (f) Prior to the sale of the Shares to the Investors,
the  Company  will  cooperate  with  the  Placement  Agent  and its  counsel  in
connection with the  registration or  qualification  of the Shares for offer and
sale under the state  securities or Blue Sky laws of such  jurisdictions  as the
Placement  Agent may  request;  provided,  that in no event shall the Company be
obligated to qualify to do business in any  jurisdiction  where it is not now so
qualified  or to take any action  which would  subject it to general  service of
process in any jurisdiction where it is not now so subject.

                           (g) During the period of three  years  commencing  on
the Effective  Date,  the Company will furnish to the Placement  Agent copies of
such financial  statements and other periodic and special reports as the Company
may from time to time  distribute  generally  to the holders of any class of its
capital stock,  and will furnish to the Placement Agent a copy of each annual or
other report it shall be required to file with the Commission.

                           (h) The  Company  will make  generally  available  to
holders of its securities, as soon as may be practicable,  but in no event later
than the last day of the fifteenth  full calendar  month  following the calendar
quarter in which the Effective  Date falls, a  consolidated  earnings  statement
(which need not be audited but shall be in reasonable detail) for a period of 12
months ended  commencing after the Effective Date, and satisfying the provisions
of Section 11(a) of the Act (including Rule 158 of the Rules and Regulations).

                           (i) The  Company  will not at any time,  directly  or
indirectly,  take any action intended, or which might reasonably be expected, to
cause or result in, or which will constitute,  stabilization of the price of the
Shares to facilitate the sale or resale of any of the Shares.

                           (j) The Company will apply the net proceeds  from the
offering and sale of the Shares in the manner set forth in the Prospectus  under
the caption "Use of Proceeds."

                  5. Expenses.  Whether or not the transactions  contemplated by
this Agreement are consummated or this Agreement is terminated, the Company will
pay all costs and expenses incident to the performance of the obligations of the
Company under this Agreement, including but not limited to costs and expenses of

         of its jurisdiction of incorporation  and is duly qualified to transact
         business as a foreign  corporation  and is in good  standing  under the
         laws of all other  jurisdictions  where the ownership or leasing of its
         properties or the conduct of its business requires such  qualification,
         except where the failure to be so qualified or in good  standing  would
         not  have  a  material  adverse  effect  on  the  business,  prospects,
         properties, condition (financial or otherwise), net worth or results of
         operations of the Company and the Subsidiaries, taken as a whole;

         and, when issued by the Company will be validly issued and outstanding;
         to such  counsel's  knowledge,  no  holders  of  outstanding  shares of
         capital stock of the Company are entitled as such to any  preemptive or
         other  rights to  subscribe  for any of the Shares;  to such  counsel's

         duly  authorized by the Company,  and the Shares,  when issued and paid
         for in accordance with this Agreement, will be duly and validly issued,

         other similar rights;  the holders of the Shares will not be subject to
         personal  liability  by reason of being such  holders;  and the Shares,
         when issued,  will conform to the description  thereof set forth in the

         Agreement require the consent, approval, authorization, registration or
         qualification  of or with any  governmental  authority,  except such as

         provisions  hereof or thereof will conflict with, or result in a breach
         or violation  of, any of the terms and  provisions  of, or constitute a
         default  under,  or result in the creation or  imposition  of any lien,
         charge or encumbrance  upon any property or assets of the Company or of
         the Subsidiaries pursuant to the terms of, (A) any material contract or

                  Gray  Cary  shall  also  state  that  in  the  course  of  the
preparation of the Registration  Statement and the Prospectus,  such counsel has
participated in conferences with officers and representatives of the Company and
with the  Accountants,  at which  conferences  the contents of the  Registration
Statement and the Prospectus  were discussed and, on the basis of the foregoing,
that they have no reason to believe that the Registration  Statement,  as of its
effective  date and as of the date of such  opinion,  contained  or contains any
untrue  statement  of a material  fact or omitted or omits to state any material
fact required to be stated therein or necessary to make the  statements  therein
not  misleading  or that  the  Prospectus,  as of its  date and the date of such
opinion,  contained  or  contains  any untrue  statement  of a material  fact or
omitted  or omits to state a  material  fact  required  to be stated  therein or
necessary  to make the  statements  therein,  in the light of the  circumstances
under which they were made, not misleading (other than

                                      -16-
<PAGE>

financial  statements  and schedules and other  financial and  statistical  data
included therein, as to which such counsel need express no view).

                  In  rendering  any such  opinion,  Gray Cary may  rely,  as to
matters of fact,  to the extent such counsel deems proper,  on  certificates  of
responsible  officers  of the Company  and public  officials  and, as to matters
involving the application of laws of any jurisdictions in which such counsel are
not admitted to practice,  to the extent  satisfactory  in form and substance to
counsel  for the  Placement  Agent,  upon  the  opinion  of local  counsel.  The
foregoing  opinion  shall also state that the  Placement  Agent is  justified in
relying upon such opinions of local  counsel,  and copies of such opinions shall
be delivered to the Placement Agent and their counsel.

                  References to the Registration Statement and the Prospectus in
this paragraph (f) shall include any amendment or supplement thereto at the date
of such opinion.

                           (g)  The  Placement  Agent  shall  have  received  an
opinion,  dated the Closing Date, of  __________________,  special  intellectual
property  counsel to the  Company,  in form and  substance  satisfactory  to the
Placement Agent, to the effect that:

                           (i) to the best of such counsel's knowledge after due
         and diligent  inquiry,  there are no legal or governmental  proceedings
         pending relating to patent rights, trade secrets,  trademarks,  service
         marks or other proprietary information or materials of the Company, and
         to the  best of  such  counsel's  knowledge  no  such  proceedings  are
         threatened or contemplated by governmental authorities or others;

                           (ii) such  counsel  do not know of any  contracts  or
         other  documents  relating to  governmental  regulation  affecting  the
         Company or the Company's patents,  trade secrets,  trademarks,  service
         marks or other  proprietary  information  or materials,  of a character
         required  to be filed as an exhibit to the  Registration  Statement  or
         required  to  be  described  in  the  Registration   Statement  or  the
         Prospectus that are not filed or described as required;

                           (iii) to the best of such counsel's  knowledge  after
         due and diligent  inquiry,  the Company is not  infringing or otherwise
         violating  any patents,  trade  secrets,  trademarks,  service marks or
         other proprietary  information or materials, of others, and to the best
         of such counsel's knowledge there are no infringements by others of any
         of the Company's patents, trade secrets,  trademarks,  service marks or
         other  proprietary  information  or materials  which in the judgment of
         such counsel could affect materially the use thereof by the Company;

                           (iv) to the best of counsel's knowledge after due and
         diligent  inquiry,  the  Company  is not aware of any  claims  that the
         technology  developed  by  Company's  scientists  while  employed by or
         associated  with the  Company  was  first  discovered  when  they  were
         employed at any other companies; and

                                      -17-
<PAGE>

                           (v) to the best of counsel's  knowledge after due and
         diligent  inquiry,  the Company is not aware of any claims of ownership
         or misappropriation  of the Company's  technology by third parties as a
         result  of  previous  employments  or  associations  of  the  Company's
         scientists with others.

         _______________  shall also state that in the course of the preparation
of the Registration Statement and the Prospectus,  such counsel has participated
in  conferences  with  officers and  representatives  of the  Company,  at which
conferences the contents of the  Registration  Statement and the Prospectus were
discussed  and,  on the  basis of the  foregoing,  that  they  have no reason to
believe  that the  Registration  Statement  or the  Prospectus  (A) contains any
untrue  statement  of a material  fact with respect to patents,  trade  secrets,
trademarks, service marks or other proprietary information or materials owned or
used by the Company,  or the manner of its use thereof, or any allegation on the
part of any person  that the  Company is  infringing  any patent  rights,  trade
secrets, trademarks, service marks or other proprietary information or materials
of any such person or (B) omits to state any material  fact relating to patents,
trade secrets,  trademarks,  service marks or other  proprietary  information or
materials owned or used by the Company, or the manner of its use thereof, or any
allegation of which such counsel have  knowledge,  that is required to be stated
in the  Registration  Statement  or the  Prospectus  or is necessary to make the
statements therein not misleading.

                  References to the Registration Statement and the Prospectus in
this paragraph (g) shall include any amendment or supplement thereto at the date
of such opinion.

                           (h)  Concurrently  with the execution and delivery of
this  Agreement,  or, if the Company elects to rely on Rule 430A, on the date of
the Prospectus,  the  Accountants  shall have furnished to the Placement Agent a
letter, dated the date of its delivery (the "Original Letter"), addressed to the
Placement Agent and in form and substance  satisfactory to the Placement  Agent,
confirming that (i) they are independent  public accountants with respect to the
Company  and the  Subsidiaries  within the  meaning of the Act and the Rules and
Regulations;   (ii)  in  their  opinion,   the  financial   statements  and  any
supplementary  financial  information  and  schedules  (and pro forma  financial
information) included in the Registration  Statement and examined by them comply
as to form in all material respects with the applicable accounting  requirements
of the Act and the Rules and Regulations;  (iii) on the basis of procedures, not
constituting  an examination  in accordance  with  generally  accepted  auditing
standards,  set forth in detail in the Original  Letter, a reading of the latest
available  interim  financial  statements  of the Company and the  Subsidiaries,
inspections  of the minute books of the Company and the  Subsidiaries  since the
latest audited  financial  statements  included in the Prospectus,  inquiries of
officials of the Company  responsible  for financial and accounting  matters and
such other  inquiries and procedures as may be specified in the Original  Letter
to a date not more  than  five days  prior to the date of the  Original  Letter,
nothing  came to their  attention  that  caused  them to believe  that:  (A) the
unaudited financial statements and schedules of the Company and the Subsidiaries
included in the  Prospectus  do not comply as to form in all  material  respects
with  the  applicable  accounting  requirements  of the Act and  the  Rules  and
Regulations,  or are not fairly presented in conformity with generally  accepted
accounting principles applied on a basis substantially consistent with the basis
for the audited financial

                                      -18-
<PAGE>

statements included in the Prospectus;  (B) any other unaudited income statement
data and balance  sheet items  included in the  Prospectus do not agree with the
corresponding items in the unaudited  financial  statements from which such data
and  items  were  derived,  and any  such  unaudited  data  and  items  were not
determined  on  a  basis  substantially   consistent  with  the  basis  for  the
corresponding  amounts  in the  audited  financial  statements  included  in the
Prospectus;  (C) the unaudited  financial  statements which were not included in
the  Prospectus but from which were derived any unaudited  financial  statements
referred to in clause (A) and any unaudited  income  statement  data and balance
sheet items  included in the Prospectus and referred to in clause (B) were to be
determined on a basis  substantially  consistent  with the basis for the audited
financial statements included in the Prospectus;  (D) as of a specified date not
more than five days prior to the date of the  Original  Letter,  there have been
any changes in the capital stock of the Company or any increase in the long-term
debt of the Company,  or any  decreases  in net current  assets or net assets or
other items  specified by the  Placement  Agent,  or any  increases in any items
specified by the Placement Agent, in each case as compared with amounts shown in
the latest  balance sheet  included in the  Prospectus,  except in each case for
changes,  increases or decreases which the Prospectus discloses have occurred or
may occur or which are described in the Original Letter;  and (E) for the period
from the date of the latest financial  statements  included in the Prospectus to
the  specified  date  referred to in Clause  (D),  there were any  decreases  in
revenues  or the  total or per  share  amounts  of net  income  or  other  items
specified by the Placement Agent, or any increases in any items specified by the
Placement  Agent,  in each case as compared  with the  comparable  period of the
preceding year and with any other period of  corresponding  length  specified by
the Placement  Agent,  except in each case for decreases or increases  which the
Prospectus  discloses  have  occurred or may occur or which are described in the
Original  Letter;  and (iv) in addition to the examination  referred to in their
reports  included in the  Prospectus  and the  procedures  referred to in clause
(iii)  above,   they  have  carried  out  certain  specified   procedures,   not
constituting  an examination  in accordance  with  generally  accepted  auditing
standards,   with  respect  to  certain   amounts,   percentages  and  financial
information specified by the Placement Agent, which are derived from the general
accounting,  financial or other records of the Company or the  Subsidiaries,  as
the case may be, which appear in the Prospectus or in Part II of, or in exhibits
or schedules  to, the  Registration  Statement,  and have compared such amounts,
percentages and financial information with such accounting,  financial and other
records  and have  found  them to be in  agreement.  At the  Closing  Date,  the
Accountants shall have furnished to the Placement Agent a letter, dated the date
of its  delivery,  which shall  confirm,  on the basis of a review in accordance
with the procedures set forth in the Original  Letter,  that nothing has come to
their attention  during the period from the date of the Original Letter referred
to in the prior sentence to a date  (specified in the letter) not more than five
days prior to the Closing  Date which would  require any change in the  Original
Letter if it were required to be dated and delivered at the Closing Date.

                           (i) At the Closing Date,  there shall be furnished to
the Placement  Agent a  certificate,  dated the date of its delivery,  signed by
each of the Chief  Executive  Officer  and the Chief  Financial  Officer  of the
Company,  in form and  substance  satisfactory  to the Placement  Agent,  to the
effect that:

                                      -19-
<PAGE>

                           (i) Each  signer of such  certificate  has  carefully
         examined the  Registration  Statement and the  Prospectus and (A) as of
         the date of such certificate,  (x) the Registration  Statement does not
         contain  any untrue  statement  of a  material  fact or omit to state a
         material  fact  required to be stated  therein or necessary in order to
         make the statements  therein not misleading and (y) the Prospectus does
         not contain any untrue  statement of a material fact or omit to state a
         material  fact  required to be stated  therein or necessary in order to
         make the statements  therein, in light of the circumstances under which
         they were made,  not  misleading  and (B) since the  Effective  Date no
         event has  occurred  as a result of which it is  necessary  to amend or
         supplement the  Prospectus in order to make the statements  therein not
         untrue or misleading in any material respect.

                           (ii) Each of the  representations  and  warranties of
         the Company contained in this Agreement were, when originally made, and
         are, at the time such certificate is delivered, true and correct in all
         material respects.

                           (iii)  Each of the  covenants  required  herein to be
         performed  by the  Company on or prior to the date of such  certificate
         has been duly,  timely and fully  performed and each  condition  herein
         required to be complied with by the Company on or prior to the delivery
         of such certificate has been duly, timely and fully complied with.

                           (iv) No stop order  suspending the  effectiveness  of
         the  Registration  Statement or of any part thereof has been issued and
         are pending or, to the  knowledge  of each  signer,  threatened  by the
         Commission.

                           (v)  Subsequent  to  the  date  of  the  most  recent
         financial  statements  in the  Prospectus,  there has been no  material
         adverse  change in the  financial  position or results of operations of
         the Company or the Subsidiaries, except as set forth in or contemplated
         by the Prospectus.

                           (j) The Shares  shall be  qualified  for sale in such
states as the Placement Agent may reasonably  request,  each such  qualification
shall be in effect and not subject to any stop order or other  proceeding on the
Closing Date.

                           (k)  The  Shares  shall  have  been   authorized  for
quotation, subject only to official notice of issuance, on the NNM.

                           (l) The Company shall have furnished to the Placement
Agent such certificates,  in addition to those specifically mentioned herein, as
the  Placement  Agent  may have  reasonably  requested  as to the  accuracy  and
completeness at the Closing Date of any statement in the Registration  Statement
or the Prospectus, as to the accuracy at the Closing Date of the representations
and  warranties  of the  Company  as to the  performance  by the  Company of its
obligations hereunder, or as to the fulfillment of the conditions concurrent and
precedent to the obligations hereunder of the Placement Agent.

                  7.  Indemnification.

                                      -20-
<PAGE>

                           (a) The Company shall indemnify and hold harmless the
Placement Agent, the directors,  officers, employees and agents of the Placement
Agent and each  person,  if any, who  controls  the  Placement  Agent within the
meaning of Section 15 of the Act or Section 20 of the Securities Exchange Act of
1934,  as amended  (the  "Exchange  Act"),  from and against any and all losses,
claims, liabilities,  expenses and damages, joint or several, (including any and
all investigative,  legal and other expenses  reasonably  incurred in connection
with,  and any amount paid in settlement  of, any action,  suit or proceeding or
any claim  asserted),  to which it, or any of them, may become subject under the
Act or other  Federal or state  statutory  law or  regulation,  at common law or
otherwise,  insofar as such  losses,  claims,  liabilities,  expenses or damages
arise  out of or are  based  on (i)  any  untrue  statement  or  alleged  untrue
statement  made by the Company in Section 3 of this  Agreement,  (ii) any untrue
statement or alleged untrue  statement of any material fact contained in (A) any
Preliminary  Prospectus,  the  Registration  Statement or the  Prospectus or any
amendment or supplement to the Registration Statement or the Prospectus, (B) any
document  incorporated by reference into the Registration  Statement and (C) any
application or other document, or any amendment or supplement thereto,  executed
by the Company based upon written  information  furnished by or on behalf of the
Company  filed in any  jurisdiction  in order to qualify  the  Shares  under the
securities  or Blue  Sky  laws  thereof  or filed  with  the  Commission  or any
securities  association or securities exchange (each, an "Application") or (iii)
the omission or alleged  omission to state in any  Preliminary  Prospectus,  the
Registration  Statement or the Prospectus or any supplement to the  Registration
Statement or the Prospectus or any document  incorporated  by reference into the
Registration  Statement or any Application a material fact required to be stated
therein  or  necessary  to  make  the  statements   therein,  in  light  of  the
circumstances in which they were made, not misleading;  provided,  however, that
the Company will not be liable to the extent that such loss,  claim,  liability,
expense or damage  arises from the sale of the Shares in the public  offering to
any person and is based  solely on an untrue  statement  or  omission or alleged
untrue  statement  or  omission  made  in  reliance  on and in  conformity  with
information  relating to the Placement Agent furnished in writing to the Company
by the Placement  Agent expressly for inclusion in the  Registration  Statement,
any Preliminary  Prospectus or the Prospectus;  and provided further,  that such
indemnity  with  respect to any  Preliminary  Prospectus  shall not inure to the
benefit of any  indemnified  person  where the person  asserting  any such loss,
claim,  damage,  liability  or action  purchased  Shares  which are the  subject
thereof to the extent that any such loss, claim, damage or liability (i) results
from the fact that  such  Placement  Agent  failed to send or give a copy of the
Prospectus  (as  amended  or  supplemented)  to such  person  at or prior to the
confirmation  of the sale of such  Shares to such  person in any case where such
delivery  is  required  by the Act and (ii)  arises  out of or is based  upon an
untrue  statement or omission of a material fact  contained in such  Preliminary
Prospectus  that was corrected in the Prospectus (or any amendment or supplement
thereto),  unless  such  failure  to  deliver  the  Prospectus  (as  amended  or
supplemented)  was the result of noncompliance by the Company with Section 4(d).
This indemnity  agreement will be in addition to any liability which the Company
may otherwise have.

                  In addition to its other obligations under this paragraph (a),
the Company agrees that, as an interim measure during the pendency of any claim,
action, investigation,  inquiry or

                                      -21-
<PAGE>

other proceeding arising out of or based upon any statement or omission,  or any
alleged  statement or omission,  or any  inaccuracy in the  representations  and
warranties  of  the  Company  in  this  Agreement  or  failure  to  perform  its
obligations in this  Agreement,  all as described in this paragraph (a), it will
reimburse the Placement Agent on a quarterly  basis for all reasonable  legal or
other expenses  incurred in connection with  investigating or defending any such
claim, action, investigation,  inquiry or other proceeding,  notwithstanding the
absence of a judicial  determination as to the propriety and  enforceability  of
the Company's obligation, to reimburse the Placement Agent for such expenses and
the possibility  that such payments might later be held to have been improper by
a  court  of  competent  jurisdiction.  To the  extent  that  any  such  interim
reimbursement  payment is so held to have been  improper,  the  Placement  Agent
shall  promptly  return it to the Company  together  with  interest,  compounded
daily,  determined on the basis of the Prime Rate (or other  commercial  lending
rate for borrowers of the highest credit  standing)  announced from time to time
by Bank of  America  National  Trust and  Savings  Association,  San  Francisco,
California (the "Prime Rate"). Any such interim reimbursement payments which are
not made to the  Placement  Agent within 30 days of a request for  reimbursement
shall bear interest at the Prime Rate from the date of such request.

                           (b) The  Placement  Agent  will  indemnify  and  hold
harmless the Company,  each person,  if any, who controls the Company within the
meaning  of  Section  15 of the Act or  Section  20 of the  Exchange  Act,  each
director  of  the  Company  and  each  officer  of the  Company  who  signs  the
Registration  Statement to the same extent as the foregoing  indemnity  from the
Company to the Placement Agent, but only insofar as losses, claims, liabilities,
expenses  or  damages  arise  out of or are  based on any  untrue  statement  or
omission or alleged  untrue  statement  or  omission  made in reliance on and in
conformity with information relating to the Placement Agent furnished in writing
to the Company by the  Placement  Agent  expressly  for use in the  Registration
Statement,  any  Preliminary  Prospectus  or  the  Prospectus.   This  indemnity
agreement  will be in addition to any liability  that the Placement  Agent might
otherwise  have.  The Company  acknowledges  that,  for all purposes  under this
Agreement,  the first,  third and fourth  legends on the inside front cover page
and the  statements  set forth under the caption "Plan of  Distribution"  in any
Preliminary  Prospectus  and the  Prospectus  constitute  the  only  information
relating  to the  Placement  Agent  furnished  in writing to the  Company by the
Placement  Agent  expressly for  inclusion in the  Registration  Statement,  any
Preliminary Prospectus or the Prospectus.

                           (c) Any party that proposes to assert the right to be
indemnified  under  this  Section 7 will,  promptly  after  receipt of notice of
commencement  of any action against such party in respect of which a claim is to
be made against an  indemnifying  party or parties  under this Section 7, notify
each such  indemnifying  party of the  commencement of such action,  enclosing a
copy of all papers served, but the omission so to notify such indemnifying party
will not relieve it from any liability that it may have to any indemnified party
under the foregoing  provisions of this Section 7 unless, and only to the extent
that, such omission results in the forfeiture of substantive  rights or defenses
by, or  otherwise  prejudices,  the  indemnifying  party.  If any such action is
brought against any indemnified party and it notifies the indemnifying  party of
its commencement, the indemnifying party will be entitled to participate in and,
to the extent that it elects by  delivering  written  notice to the  indemnified
party promptly 

                                      -22-
<PAGE>

after  receiving  notice of the  commencement of the action from the indemnified
party,  jointly with any other indemnifying party similarly notified,  to assume
the defense of the action,  with counsel  satisfactory to the indemnified party,
and after notice from the  indemnifying  party to the  indemnified  party of its
election to assume the defense, the indemnifying party will not be liable to the
indemnified  party for any legal or other expenses  except as provided below and
except for the reasonable  costs of  investigation  incurred by the  indemnified
party in connection with the defense.  The indemnified party will have the right
to employ its own counsel in any such action,  but the fees,  expenses and other
charges of such counsel will be at the expense of such indemnified  party unless
(1) the employment of counsel by the  indemnified  party has been  authorized in
writing by the  indemnifying  party,  (2) the  indemnified  party has reasonably
concluded  (based on advice of counsel) that a conflict  exists (based on advice
of counsel to the  indemnified  party)  between  the  indemnified  party and the
indemnifying  party that would prevent the counsel  selected by the indemnifying
party from  representing  the indemnified  party (in which case the indemnifying
party will not have the right to direct the  defense of such action on behalf of
the indemnified  party) or (3) the  indemnifying  party has not in fact employed
counsel to assume the  defense of such  action  within a  reasonable  time after
receiving notice of the  commencement of the action,  in each of which cases the
reasonable  fees,  disbursements  and other  charges of  counsel  will be at the
expense  of the  indemnifying  party  or  parties.  It is  understood  that  the
indemnifying  party or parties shall not, in connection  with any  proceeding or
related proceedings in the same jurisdiction, be liable for the reasonable fees,
disbursements  and other  charges of more than one  separate  firm  admitted  to
practice in such  jurisdiction at any one time for all such indemnified party or
parties.  All such fees,  disbursements  and other charges will be reimbursed by
the  indemnifying  party  promptly as they are  incurred.  The Company will not,
without the prior written consent of the Placement  Agent,  settle or compromise
or consent to the entry of any  judgment  in any  pending or  threatened  claim,
action,  suit or proceeding in respect of which  indemnification has been sought
hereunder  (whether or not the  Placement  Agent or any person who  controls the
Placement Agent within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act is a party to such claim, action, suit or proceeding),  unless such
settlement,  compromise  or consent  includes  an  unconditional  release of the
Placement Agent and each such controlling  person from all liability arising out
of such claim,  action,  suit or proceeding.  An indemnifying  party will not be
liable for any  settlement of any action or claim  effected  without its written
consent (which consent will not be unreasonably withheld).

                           (d) In  order  to  provide  for  just  and  equitable
contribution in circumstances in which the  indemnification  provided for in the
foregoing  paragraphs of this Section 7 is  applicable  in  accordance  with its
terms  but for any  reason is held to be  unavailable  from the  Company  or the
Placement  Agent,  the Company and the  Placement  Agent will  contribute to the
total  losses,  claims,   liabilities,   expenses  and  damages  (including  any
investigative,  legal and other expenses reasonably incurred in connection with,
and any amount paid in  settlement  of, any action,  suit or  proceeding  or any
claim  asserted,  but after deducting any  contribution  received by the Company
from  persons  other than the  Placement  Agent such as persons  who control the
Company  within the  meaning of the Act or the  Exchange  Act,  officers  of the
Company who signed the Registration  Statement and directors of the Company, who
also may be liable for  contribution)  to which the  Company  and the  Placement
Agent may 

                                      -23-
<PAGE>

be subject in such  proportion as shall be  appropriate  to reflect the relative
benefits  received by the Company on the one hand and the Placement Agent on the
other.  The  relative  benefits  received by the Company on the one hand and the
Placement Agent on the other shall be deemed to be in the same proportion as the
total  net  proceeds  from the  offering  (before  deducting  Company  expenses)
received  by the  Company  as set forth in the  table on the  cover  page of the
Prospectus  bear to the fee received by the Placement Agent  hereunder.  If, but
only if, the allocation  provided by the foregoing  sentence is not permitted by
applicable law, the allocation of contribution  shall be made in such proportion
as is appropriate to reflect not only the relative  benefits  referred to in the
foregoing sentence but also the relative fault of the Company,  on the one hand,
and the  Placement  Agent  on the  other,  with  respect  to the  statements  or
omissions which resulted in such loss, claim,  liability,  expense or damage, or
action  in  respect   thereof,   as  well  as  any  other   relevant   equitable
considerations  with  respect to such  offering.  Such  relative  fault shall be
determined by reference to whether the untrue or alleged  untrue  statement of a
material  fact or omission or alleged  omission to state a material fact relates
to information supplied by the Company or the Placement Agent, the intent of the
parties and their relative  knowledge,  access to information and opportunity to
correct or prevent such  statement or  omission.  The Company and the  Placement
Agent agree that it would not be just and equitable if contributions pursuant to
this Section 7(d) were to be determined  by pro rata  allocation or by any other
method  of   allocation   which  does  not  take  into  account  the   equitable
considerations  referred to herein. The amount paid or payable by an indemnified
party as a result of the loss, claim, liability, expense or damage, or action in
respect  thereof,  referred  to above in this  Section  7(d)  shall be deemed to
include,  for  purpose  of this  Section  7(d),  any  legal  or  other  expenses
reasonably  incurred by such indemnified party in connection with  investigating
or defending any such action or claim.  Notwithstanding  the  provisions of this
Section 7(d), the Placement Agent shall not be required to contribute any amount
in excess of the fee received by it, and no person  found  guilty of  fraudulent
misrepresentation  (within  the  meaning  of  Section  11(f) of the Act) will be
entitled to  contribution  from any person who was not guilty of such fraudulent
misrepresentation.  For purposes of this Section 7(d), any person who controls a
party to this  Agreement  within the meaning of the Act or the Exchange Act will
have the same  rights to  contribution  as that party,  and each  officer of the
Company  who  signed the  Registration  Statement  will have the same  rights to
contribution as the Company,  subject in each case to the provisions hereof. Any
party entitled to contribution, promptly after receipt of notice of commencement
of any action  against  such party in respect of which a claim for  contribution
may be made under this Section 7(d),  will notify any such party or parties from
whom contribution may be sought,  but the omission so to notify will not relieve
the  party or  parties  from  whom  contribution  may be  sought  from any other
obligation  it or they may have under this Section 7(d). No party will be liable
for contribution with respect to any action or claim settled without its written
consent (which consent will not be unreasonably withheld).

                  8.  Termination.

                           (a) The obligations of the Placement Agent under this
Agreement  may be terminated at any time prior to the Closing Date, by notice to
the Company  from the  Placement  Agent,  without  liability  on the part of the
Placement Agent to the Company if, prior to delivery and payment for the Shares,
in the sole judgment of the  Placement  Agent (i) trading

                                      -24-
<PAGE>

in the Common Stock of the Company shall have been  suspended by the  Commission
or by the NNM,  (ii)  trading  in  securities  generally  on the New York  Stock
Exchange or the NNM shall have been  suspended  or limited or minimum or maximum
prices  shall  have been  generally  established  on any of such  exchanges,  or
additional material governmental restrictions,  not in force on the date of this
Agreement,  shall have been imposed upon trading in securities  generally by any
of  such  exchanges  or by  order  of the  Commission  or  any  court  or  other
governmental  authority,  (iii) a general  banking  moratorium  shall  have been
declared by Federal or New York State  authorities or (iv) any material  adverse
change in the  financial  or  securities  markets  in the  United  States or any
outbreak or material  escalation of  hostilities  or  declaration  by the United
States of a national  emergency  or war or other  calamity or crisis  shall have
occurred, the effect of any of which is such as to make it, in the sole judgment
of the Placement Agent, impracticable or inadvisable to market the Shares on the
terms and in the manner contemplated by the Prospectus.

                           (b)  The   obligations  of  the  parties  under  this
Agreement  shall be  automatically  terminated  in the event that the  Requisite
Funds have not been  deposited by the Investors  into the Escrow  Account by the
close of business on the date scheduled for the Closing.

                  9. Notices.  Notice given pursuant to any of the provisions of

agreements,  covenants,  indemnities  and other  statements of the Company,  its
officers and the  Placement  Agent set forth in this  Agreement or made by or on

force and effect,  regardless of (i) any  investigation  made by or on behalf of
the  Company,  any of its  officers or  directors,  the  Placement  Agent or any
controlling  person  referred  to in Section 7 hereof and (ii)  delivery  of and
payment for the Shares. The respective  agreements,  covenants,  indemnities and
other statements set forth in Sections 5 and 7 hereof shall remain in full force
and effect, regardless of any termination or cancellation of this Agreement.

                  11.  Successors.  This Agreement shall inure to the benefit of
and shall be binding upon the Placement  Agent, the Company and their respective
successors and legal representatives, and nothing expressed or mentioned in this
Agreement  is intended or shall be  construed to give any other person any legal

provisions  hereof  being  intended  to be and being for the sole and  exclusive

signed the  Registration  Statement  and any person or persons  who  control the
Company  within  the  meaning  of  Section  15 of the Act or  Section  20 of the
Exchange Act. No Investor shall be deemed a successor because of such purchase.

                  12.  Headings.  Section  headings  in this  Agreement  are for
convenience of reference only, do not constitute a part of this  Agreement,  and
shall not affect its interpretation.

                                    EXHIBIT A


                                ESCROW AGREEMENT


                  ESCROW  AGREEMENT,  dated as of  ______________,  1997, by and
among SCICLONE PHARMACEUTICALS,  INC., a California corporation (the "Company"),
EVEREN  SECURITIES,  INC. (the "Placement  Agent") and ____________,  a national
banking institution  incorporated under the laws of the United States of America
(the "Escrow Agent").

                  WHEREAS,   the  Company  proposes  to  sell  an  aggregate  of
1,500,000  shares of its  common  stock,  no par value  (the  "Shares"),  for an
aggregate of $_______,  all as described in the Company's registration statement
on Form S-3 (Registration No. 333-_____)(which,  together with all amendments or
supplements thereto is referred to herein as the "Registration Statement");

                  WHEREAS,  the  Shares  are being  offered  by the  Company  to
investors whom the Placement  Agent has  introduced to the Company,  pursuant to
registration  under the  Securities  Act of 1933,  as amended,  and  pursuant to
registration or exemptions from registration under state securities laws;

                  WHEREAS,   the  offering  of  the  Shares  will  terminate  on
_________,  1997 (the "Final Closing Date") and, if subscriptions  for the total
number of Shares being offered pursuant to the  Registration  Statement have not
been received by the Company on or before the Final Closing Date, no Shares will
be sold and all  payments  made by  subscribers  will be  refunded by the Escrow
Agent with interest earned thereon, if any; and

                  WHEREAS,  with respect to all subscription  payments  received
from  subscribers,  the Company proposes to establish an escrow account with the
Escrow Agent at the office of its Escrow Administration, [street address].

                  NOW, THEREFORE, it is agreed as follows:

                  1.  Establishment of Escrow. The Escrow Agent hereby agrees to
receive  and  disburse  the  proceeds  from the  offering  of the Shares and any
interest earned thereon in accordance herewith.

                  2.  Deposit of Escrowed  Property.  The  Placement  Agent,  on
behalf of the  subscribers  for the Shares,  shall from time to time,  but in no
event  later  than  12:00 noon on the date  following  receipt by the  Placement
Agent, cause to be wired to or deposited with, or, cause the subscribers for the
Shares  to wire or  deposit  with,  the  Escrow  Agent  funds or  checks  of the
subscribers  delivered  in payment for Shares  (the  "Escrowed  Property").  Any
checks  delivered to the Escrow Agent pursuant to the terms hereof shall be made
payable to or endorsed to the order of the Escrow  Agent.  The Escrow Agent upon
receipt of such checks shall present such checks for

<PAGE>

payment to the  drawee-bank  under such  checks.  Any checks not  honored by the
drawee-bank thereunder after the first presentment for payment shall be returned
to the Placement Agent, on behalf of such subscriber, in the same manner notices
are  delivered  pursuant to Section 6. Upon  receipt of funds or checks from the
Placement Agent, the Escrow Agent shall credit such funds and the amount of such
checks to a  non-interest-bearing  account  (the "Escrow  Account")  held by the
Escrow  Agent.  If following the credit of the amount of any check to the Escrow
Account such check is dishonored,  the Escrow Agent,  if such  dishonored  check
amount shall have been  invested  pursuant to Section 3, shall  liquidate to the
extent of such  dishonored  check amount such  investments  and debit the Escrow
Account  for the amount of such  dishonored  check plus,  if any,  the amount of
interest  and  other  income  earned  with  respect  to any  investment  of such
dishonored check amount.

                  3.  Investment of Escrowed  Property.  The Escrow Agent on the
second  business  day  ("business  day"  defined  for  purposes  of this  Escrow
Agreement  as any day which is not a Saturday,  a Sunday or a day on which banks
or trust companies in the City and State of New York are authorized or obligated
by law,  regulation or executive order to remain closed) succeeding (unless such
deposit is made in federal or other  immediately  available or "same day" funds,
in  which  case,  on  the  business  day  next  succeeding)  the  credit  of any
subscription  proceeds  to the Escrow  Account  pursuant  to Section 2 and until
release of such proceeds in accordance with the terms hereof, shall deposit such
proceeds in a __________ Money Market Deposit  Account,  pursuant to Rule 15c2-4
promulgated  by the  Securities  and Exchange  Commission  under the  Securities
Exchange  Act of 1934,  as amended,  in  accordance  with the terms set forth on
Exhibit A hereto (made a part of this Escrow  Agreement as if herein set forth).
The Escrow  Agent  shall in no event be liable for any loss  resulting  from any
change in  interest  rates  applicable  to  proceeds  invested  pursuant to this
Section.  Interest on proceeds  invested  pursuant to this Section  shall accrue
from the date of  investment  of such  proceeds  until the  termination  of such
investment  pursuant  to the  terms  hereof  and  shall be paid as set  forth in
Section 5.

                  The parties  recognize that in authorizing the Escrow Agent to
invest  principal and income cash balances held as Escrowed  Property into money
market  instruments  or deposits that are  obligations  of __________ or related
entities,  in addition to the fees  provided  for herein,  the Escrow Agent or a
related  entity  may also  receive  a  benefit  or  profit  from the use of such
obligations.  The parties hereby authorize the receipt of such benefit or profit
and expressly  waive any special  computation  or  accounting.  The Escrow Agent
hereby agrees to provide the parties with periodic  statements  describing  such
obligations  and reporting the interest  earned  thereon so that the parties may
review and evaluate the  transactions  effected by the Escrow Agent  pursuant to
this authorization.

                  4. List of  Subscribers.  The Placement Agent shall furnish or
cause to be furnished to the Escrow Agent,  at the time of each deposit of funds
or checks pursuant to Section 2, a list,  substantially in the form of Exhibit B
hereto,  containing the name of, the address of, the number of Shares subscribed
for by, the subscription  amount delivered to the Escrow Agent on behalf of, and
the social security or taxpayer  identification number, if applicable,  of, each
subscriber 

                                      -2-
<PAGE>

whose funds are being  deposited,  and to which is attached a completed W-9 form
(or,  in the  case of any  subscriber  who is not a  United  States  citizen  or
resident, a W-8 form) for each listed subscriber.  The Escrow Agent shall notify
the Placement Agent and the Company of any discrepancy  between the subscription
amounts  set  forth on any list  delivered  pursuant  to this  Section 4 and the
subscription  amounts  received  by  the  Escrow  Agent.  The  Escrow  Agent  is
authorized  to revise  such list to  reflect  the  actual  subscription  amounts
received and the release of any subscription amounts pursuant to Section 5.

                  5. Withdrawal of Subscription Amounts. (a) If the Escrow Agent
shall  receive  a notice,  substantially  in the form of  Exhibit  C hereto  (an
"Offering  Termination  Notice"),  from the Company,  the Escrow Agent shall (i)
promptly after receipt of such Offering  Termination Notice and the clearance of
all checks  received by the Escrow  Agent as Escrowed  Property,  liquidate  any
investments  that  shall have been made  pursuant  to Section 3 and send to each
subscriber  listed on the list held by the Escrow  Agent  pursuant  to Section 4
whose  total  subscription  amount  shall not have  been  released  pursuant  to
paragraph (b) or (c) of this Section 5, in the manner set forth in paragraph (d)
of this Section 5, a check to the order of such  subscriber in the amount of the
remaining subscription amount held by the Escrow Agent as set forth on such list
held by the Escrow Agent, and (ii) promptly after the fourth business day of the
month immediately  following the month in which the investments made pursuant to
Section 3 were terminated  pursuant to this  paragraph,  send, in the manner set
forth in  paragraph  (e) of this  Section  5, a check to the  order of each such
subscriber  in the amount of interest and other  income  earned and not yet paid
with respect to any  investment  of such  subscriber's  funds.  The Escrow Agent
shall notify the Company and the  Placement  Agent of the  distribution  of such
funds to the subscribers.

                           (b) In the  event  that  (i)  the  Shares  have  been
subscribed  for and funds in respect  thereof shall have been deposited with the
Escrow  Agent  on or  before  the  Final  Closing  Date  and  (ii)  no  Offering
Termination  Notice shall have been  delivered to the Escrow Agent,  the Company
and the  Placement  Agent,  shall  deliver to the Escrow  Agent a joint  notice,
substantially in the form of Exhibit D hereto (a "Closing Notice"),  designating
the date on which Shares are to be sold and delivered to the subscribers thereof
(the "Closing Date"),  which date shall not be earlier than the clearance of any
checks received by the Escrow Agent as Escrowed Property,  the proceeds of which
are to be distributed on such Closing Date, and  identifying the subscribers and
the number of Shares to be sold to each thereof on such Closing  Date,  not less
than two (2) nor more than seven (7) business  days prior to such Closing  Date.
The Escrow Agent, after receipt of such Closing Notice and the clearance of such
checks:

                           (i) on or prior to the  Closing  Date  identified  in
         such Closing Notice,  shall  liquidate any investments  that shall have
         been  made  pursuant  to  Section 3 to the  extent of the  subscription
         amount to be distributed pursuant to the immediately  succeeding clause
         (ii);

                           (ii) on such Closing Date, pay to the Company and the
         Placement  Agent, in federal or other  immediately  available funds and
         otherwise  in the  manner  specified  by the  Company  in such  Closing
         Notice,  an amount equal to the aggregate of the  subscription 

                                      -3-
<PAGE>

         amounts paid by the  subscribers  identified in such Closing Notice for
         the  Shares  to be sold on such  Closing  Date as set forth on the list
         held by the Escrow Agent pursuant to Section 4; and

                           (iii) promptly  after the fourth  business day of the
         month  immediately  following the month in which the  investments  made
         pursuant to Section 3 were terminated  pursuant to such Closing Notice,
         shall send, in the manner set forth in paragraph (e) of this Section 5,
         a check to the  order of each  subscriber  identified  in such  Closing
         Notice in the amount of interest  and other  income  earned and not yet
         paid with respect to any  investment  of each such  subscriber's  funds
         distributed  on such Closing  Date. At the time of such  transfer,  the
         Escrow Agent shall identify in writing to the Company and the Placement
         Agent  the  amount  of the  interest  earned  for the  account  of each
         subscriber and the date such subscription was received.

                           (c) If at any time and from time to time prior to the
release of any subscriber's total subscription  amount pursuant to paragraph (a)
or (b) of this Section 5 from escrow,  the Company  shall  deliver to the Escrow
Agent a notice,  substantially  in the form of Exhibit E hereto (a "Subscription
Termination Notice"), to the effect that any or all of the subscriptions of such
subscriber  have been rejected by the Company (a "Rejected  Subscription"),  the
Escrow Agent (i) promptly after receipt of such Subscription  Termination Notice
and,  if  such  subscriber   delivered  a  check  in  payment  of  its  Rejected
Subscription,  after the clearance of such check, shall liquidate, to the extent
of the sum of such subscriber's Rejected Subscription amount as set forth in the
Subscription  Termination  Notice,  any  investments  that  shall have been made
pursuant  to Section 3 and send to such  subscriber,  in the manner set forth in
paragraph (e) of this Section 5, a check to the order of such  subscriber in the
amount of such Rejected  Subscription amount, and (ii) promptly after the fourth
business  day  of the  month  immediately  following  the  month  in  which  the
investments  made  pursuant  to  Section  3 were  terminated  pursuant  to  this

(e) of this Section 5, a check to the order of such  subscriber in the amount of
interest and other income earned and not yet paid with respect to any investment
of such subscriber's Rejected Subscription amount. At the time of such transfer,
the Escrow  Agent shall  identify  in writing to the  Company and the  Placement
Agent the amount of the interest  earned for the account of each  subscriber and
the date such subscription was received.

                           (d) On a date  following the transfer of any interest
earned for the account of each subscriber  pursuant to Section 5(a), (b) or (c),
but not later  than  _________,  199_,  the  Escrow  Agent  shall  provide  each
subscriber with tax form 1099 setting forth the amount of such interest.

                           (e) For the  purposes  of this  Section  5, any check
that the Escrow Agent shall be required to send to any subscriber  shall be sent

or to such other  address  as the person to whom  notice is to be given may have
previously  furnished  to the others in the  above-referenced  manner.  All such
notices and communications,  if mailed, shall

                                      -5-

be effective when deposited in the mails, except that notices and communications
to the Escrow  Agent and  notices of changes of address  shall not be  effective
until received.

                  7.  Concerning the Escrow Agent. To induce the Escrow Agent to
act hereunder, it is further agreed by the Company and Placement Agent that:

                           (a) The Escrow  Agent  shall not be under any duty to
give the Escrowed  Property held by it hereunder any greater degree of care than
it gives its own similar  property and shall not be required to invest any funds
held hereunder  except as directed in this Escrow  Agreement.  Uninvested  funds
held hereunder shall not earn or accrue interest.

                           (b) This Escrow  Agreement  expressly  sets forth all
the duties of the Escrow  Agent with  respect to any and all  matters  pertinent
hereto.  No  implied  duties  or  obligations  shall be read  into  this  Escrow
Agreement  against the Escrow Agent.  The Escrow Agent shall not be bound by the
provisions  of any agreement  among the other parties  hereto except this Escrow
Agreement.

                           (c) The Escrow Agent shall not be liable,  except for
its own gross  negligence  or willful  misconduct,  and,  except with respect to
claims  based  upon  such  gross  negligence  or  willful  misconduct  that  are
successfully  asserted  against the Escrow Agent,  and the other parties  hereto
shall  jointly and  severally  indemnify and hold harmless the Escrow Agent (and
any successor  Escrow  Agent) from and against any and all losses,  liabilities,
claims, actions, damages and expenses,  including reasonable attorneys' fees and
disbursements,  arising out of and in  connection  with this  Escrow  Agreement.
Without limiting the foregoing,  the Escrow Agent shall in no event be liable in
connection  with its investment or reinvestment of any cash held by it hereunder
in good faith, in accordance with the terms hereof, including without limitation
any liability  for any delays (not  resulting  from gross  negligence or willful
misconduct) in the investment or reinvestment of the Escrowed  Property,  or any
loss of interest incident to any such delays.

                           (d) The Escrow  Agent  shall be entitled to rely upon
any order, judgment, certification,  demand, notice, instrument or other writing
delivered to it hereunder  without being required to determine the  authenticity
or the  correctness  of any fact stated  therein or the propriety or validity of
the service thereof. The Escrow Agent may act in reliance upon any instrument or
signature  believed by it in good faith to be genuine and may assume, if in good
faith,  that any person  purporting  to give notice or receipt or advice or make
any statement or execute any document in connection  with the provisions  hereof
has been duly authorized to do so.

                           (e) The Escrow  Agent may act  pursuant to the advice
of counsel  with  respect to any matter  relating to this Escrow  Agreement  and
shall  not be  liable  for any  action  taken or  omitted  in good  faith and in
accordance with such advice.

                           (f) The Escrow  Agent does not have any  interest  in
the Escrowed Property deposited  hereunder but is serving as escrow holder only.
Any payments of income from 

                                      -6-
<PAGE>

the Escrow  Account shall be subject to  withholding  regulations  then in force
with respect to United States taxes.  The parties hereto will provide the Escrow
Agent  with  appropriate  W-9  forms  for tax  I.D.,  number  certification,  or
non-resident alien certifications.

                           This  paragraph (f) and paragraph (c) of this Section
7 shall survive  notwithstanding any termination of this Escrow Agreement or the
resignation of the Escrow Agent.

                           (g) The Escrow  Agent makes no  representation  as to
the validity,  value, genuineness or the collectibility of any security or other
document or instrument held by or delivered to it.

                           (h) The  Escrow  Agent  shall not be  called  upon to
advise  any  party as to the  wisdom  of  selling  or  retaining  or  taking  or
refraining  from any action with  respect to any  securities  or other  property
deposited hereunder.

                           (i) The Escrow Agent (and any successor escrow agent)
at any time may be discharged from its duties and  obligations  hereunder by the
delivery  to it of notice of  termination  signed  by both the  Company  and the
Placement  Agent or at any time may  resign  by  giving  written  notice to such
effect to the Company and the  Placement  Agent.  Upon any such  termination  or
resignation,  the Escrow  Agent  shall  deliver  the  Escrowed  Property  to any
successor  escrow  agent  jointly  designated  by the  other  parties  hereto in
writing,  or to any court of competent  jurisdiction if no such successor escrow
agent is agreed upon, whereupon the Escrow Agent shall be discharged of and from
any  and  all  further  obligations  arising  in  connection  with  this  Escrow
Agreement.  The termination or resignation of the Escrow Agent shall take effect
on the  earlier of (i) the  appointment  of a  successor  (including  a court of
competent  jurisdiction)  or (ii)  the day  that is 30 days  after  the  date of
delivery: (A) to the Escrow Agent of the other parties' notice of termination or
(B) to the  other  parties  hereto  of the  Escrow  Agent's  written  notice  of
resignation.  If at that time the Escrow Agent has not received a designation of
a successor escrow agent, the Escrow Agent's sole responsibility after that time
shall be to keep the Escrowed  Property safe until  receipt of a designation  of
successor escrow agent or a joint written  disposition  instruction by the other
parties hereto or any enforceable order of a court of competent jurisdiction.

                           (j) The Escrow Agent shall have no responsibility for
the contents of any writing of any third party contemplated herein as a means to
resolve disputes and may rely without any liability upon the contents thereof.

                           (k) In the event of any disagreement among or between
the other  parties  hereto  and/or the  subscribers  of the Shares  resulting in
adverse claims or demands being made in connection  with the Escrowed  Property,
or in the  event  that the  Escrow  Agent  in good  faith is in doubt as to what
action it should take  hereunder,  the Escrow  Agent shall be entitled to retain
the Escrowed Property until the Escrow Agent shall have received (i) a final and
non-appealable order of a court of competent  jurisdiction directing delivery of
the Escrowed Property or (ii) a written agreement  executed by the other parties
hereto and consented to by the  subscribers  directing 

                                      -7-
<PAGE>

delivery  of the  Escrowed  Property,  in which  event the  Escrow  Agent  shall
disburse the Escrowed  Property in accordance with such order or agreement.  Any
court order  referred to in (i) above shall be accompanied by a legal opinion by
counsel for the presenting party  satisfactory to the Escrow Agent to the effect
that said court order is final and non-appealable. The Escrow Agent shall act on
such court order and legal opinion without further question.

                           (l) As  consideration  for  its  agreement  to act as
Escrow Agent as herein described, the Company agrees to pay the Escrow Agent the
fee set forth on Exhibit F hereto  (made a part of this Escrow  Agreement  as if
herein set forth). In addition, the Company agrees to reimburse the Escrow Agent
for all reasonable expenses,  disbursements and advances incurred or made by the
Escrow Agent in performance of its duties hereunder (including  reasonable fees,
expenses and disbursements of its counsel).

                           (m) All parties hereto  irrevocably (i) submit to the
jurisdiction  of any New York State or federal court sitting in New York City in
any action or  proceeding  arising out of or relating to this Escrow  Agreement,
(ii) agree that all claims with  respect to such action or  proceeding  shall be
heard and determined in such New York State or federal court and (iii) waive, to
the fullest extent  possible,  the defense of an inconvenient  forum.  The other
parties hereby consent to and grant any such court jurisdiction over the persons
of such  parties and over the subject  matter of any such dispute and agree that
delivery  or  mailing of process  or other  papers in  connection  with any such
action or proceeding in the manner provided hereinabove, or in such other manner
as may be permitted by law, shall be valid and sufficient service thereof.

                           (n) No  printed  or  other  matter  in  any  language
(including,  without  limitation,  the Registration  Statement,  the Prospectus,
notices,  reports and  promotional  material)  which mentions the Escrow Agent's
name or the rights, powers, or duties of the Escrow Agent shall be issued by the
other parties  hereto or on such  parties'  behalf unless the Escrow Agent shall
first have given its specific written consent  thereto.  The Escrow Agent hereby
consents to the use of its name and the reference to the escrow  arrangement  in
the Registration Statement and in the Prospectus.

                  8.       Miscellaneous.

                           (a) This Escrow  Agreement  shall be binding upon and
inure  solely  to the  benefit  of  the  parties  hereto  and  their  respective
successors  and assigns,  heirs,  administrators  and  representatives,  and the
subscribers  of the  Shares  and  shall  not be  enforceable  by or inure to the
benefit of any other third party except as provided in paragraph  (i) of Section
7 with respect to the  termination  of, or resignation  by, the Escrow Agent. No
party may assign any of its rights or  obligations  under this Escrow  Agreement
without the written consent of the other parties.

                           (b)  This  Escrow  Agreement  shall be  construed  in
accordance  with  and  governed  by the  internal  law of the  State of New York
(without reference to its rules as to conflicts of law).

                                      -8-
<PAGE>

                           (c) This Escrow  Agreement  may only be modified by a
writing signed by all of the parties hereto and consented to by the  subscribers
of the Shares  adversely  affected by such  modifications.  No waiver  hereunder
shall be effective unless in a writing signed by the party to be charged.

                           (d) This Escrow  Agreement  shall  terminate upon the
payment pursuant to Section 5 of all amounts held in the Escrow Account.

                           (e) The section  headings  herein are for convenience
only and shall not affect the construction thereof.  Unless otherwise indicated,
references to Sections are to Sections contained herein.

                           (f) This Escrow  Agreement  may be executed in one or
more  counterparts but all such separate  counterparts  shall constitute but one
and the same instrument;  provided that, although executed in counterparts,  the
executed  signature  pages of each such  counterpart  may be affixed to a single
copy of this Agreement which shall constitute an original.
