   Scios is a biopharmaceutical company engaged in the discovery, development 
and commercialization of novel human therapeutics.  The Company focuses its 
proprietary research and development efforts on products to treat acute 
illnesses, primarily in the areas of cardiovascular and renal diseases, and 
seeks to collaborate with corporate partners in the development of products 
to treat chronic diseases.  In addition to activities involving both 
protein-based and small-molecule drug discovery and development, the Company 
has a marketing and sales organization selling third-party products that 
generate cash to help fund continued development of the Company's proprietary 
products, none of which to date has been developed to the commercialization 
stage.

   The Company directs its resources towards the development of proprietary 
products that address acute illnesses, primarily in the areas of 
cardiovascular and renal diseases.  The Company's lead products for acute 
conditions are AURICULIN-Registered Trademark- anaritide for the treatment of 
oliguric acute renal failure (acute renal failure in patients with abnormally 
low urine output) which is being developed with Genentech, Inc. and 
NATRECOR-Registered Trademark-BNP for the treatment of acute congestive heart 
failure.

   In May 1995, the Company announced the results of a 500-patient Phase III 
clinical trial (the "ARF-Phase III") of AURICULIN-Registered Trademark- for 
the treatment of acute renal failure in the broad population of acute renal 
failure patients ("ARF").  The results of the ARF-Phase III showed no 
significant reduction in the need for dialysis and no significant reduction 
in mortality in the broad population of ARF patients.  However, the ARF-Phase 
III did show the potential for the use of AURICULIN-Registered Trademark- 
anaritide for reduction in the need for dialysis in a prospectively-defined 
subgroup of ARF patients (approximately 24% of the broad population of acute 
renal failure patients) suffering from oliguric acute renal failure ("OARF" 
trial).  Treatment with AURICULIN-Registered Trademark- anaritide did not 
reduce mortality in patients suffering from OARF.

   Based upon the results of this study, discussions with the Food and Drug 
Administration ("FDA"), and quantitative market research indicating that OARF 
affects up to 80,000 patients in the United States each year, in October 1995 
Scios initiated a Phase III clinical study of AURICULIN-Registered 
Trademark-anaritide for the treatment of OARF (the "OARF-Phase III" trial). 
As with all clinical studies, looking forward, there can be no assurance the 
results of the OARF-Phase III will be similar to those achieved in the 
ARF-Phase III or will otherwise be successful.

   NATRECOR is currently in Phase II clinical studies for the treatment of 
acute congestive heart failure.  The Company is also continuing preclinical 
studies of its anti-inflammatory compounds.

   Therapies for chronic conditions, such as FIBLAST-TM- bFGF growth factor 
for wound healing, insulinotropin for Type II diabetes and a treatment for 
Alzheimer's disease, are being developed by corporate partners or by Scios 
with funding from corporate partners.  Under its arrangements with corporate 
partners, Scios typically receives research and development funding, payments 
for clinical supplies and/or milestone payments for achieving scientific and 
clinical benchmarks.  The Company also is entitled to royalties on commercial 
sales of products and, in some cases, may receive additional revenues from 
the manufacture of products.

   Scios's financial strategy involves careful management of its cash through 
targeted investment in its acute-care pipeline, while supporting these 
efforts with cash flow from its commercial operations and from corporate 
partner funded projects.

   Scios was formed through the September 1992 merger (the "Merger") of 
Scios Inc., a Delaware corporation ("Scios"), and Nova Pharmaceutical 
Corporation, a Delaware corporation ("Nova").  The Merger brought together 
Scios' expertise in producing recombinant proteins with Nova's expertise in 
synthesizing small molecules.  As a result, Scios has capabilities in 
molecular and cell biology, protein and medicinal chemistry, molecular 
modeling, pharmacology and the bioprocessing sciences, and has the tools to 
undertake the rational design of small molecules based on knowledge of the 
associated design targets.  The Company also acquired Nova's sales force and 
a line of marketed psychiatric products which constitute the Company's 
present commercial operations.

   The Company was incorporated in California in 1981 under the name 
California Biotechnology, Inc. and reincorporated in Delaware in 1988.  The 
Company changed its name to Scios Inc. in February 1992 and to Scios Nova 
Inc. in September 1992 following the Merger and reverted to the name Scios 
Inc. in March 1996.  The principal executive offices of the Company are 
located at 2450 Bayshore Parkway, Mountain View, California 94043.  The 
telephone number at that location is (415) 966-1550.

                                  RISK FACTORS

   THE FOLLOWING ARE SIGNIFICANT RISK FACTORS THAT SHOULD BE CONSIDERED 
CAREFULLY IN EVALUATING THE COMMON STOCK OF SCIOS.

NO ASSURANCE OF SUCCESSFUL AND TIMELY PRODUCT DEVELOPMENT AND APPROVAL OF 
PRODUCTS UNDER DEVELOPMENT

   Scios focuses its product development efforts on proprietary therapeutics 
for acute illnesses, principally in the areas of cardiovascular and renal 
diseases.  The Company's success will depend on its ability to achieve 
scientific and technological advances and to translate such advances into 
reliable, commercially competitive products on a timely basis.  Scios's 
products are at various stages of research and development and further 
development and testing will be required to determine their technical 
feasibility and commercial viability.  Most of these products are not likely 
to become commercially available, if at all, for several more years at the 
earliest.  The proposed development schedules for the Company's products may 
be affected by a variety of factors, including technological difficulties, 
proprietary technology of others, reliance on third parties for support and 
changes in governmental regulation, many of which factors will not be within 
the control of Scios.  Of all the Company's potential products, 
AURICULIN-Registered Trademark- anaritide, which is being developed with 
Genentech, Inc., is at the most advanced stage of development.  AURICULIN 
anaritide originally had been developed by Scios as a treatment for the broad 
population of ARF patients but proved ineffective in such application in the 
ARF-Phase III trial.  The Company currently is developing AURICULIN anaritide 
for the treatment of OARF but there can be no assurance that the ongoing 
OARF-Phase III trial will be successful.  See "Risk Factors-Uncertainty 
Regarding AURICULIN Anaritide" and "-Relationship with Genentech."  Any 
delay in the development, introduction or marketing of the Company's 
potential products could result either in such products being marketed at a 
time when their cost and performance characteristics would not be competitive 
in the marketplace or in a shortening of their commercial lives.

UNCERTAINTY REGARDING AURICULIN ANARITIDE.

   In May 1995, the Company announced the results of the ARF-Phase III trial. 
Such study did not show any significant reduction in the need for dialysis or 
mortality among the broad population of ARF patients.  This study did show a 
significant reduction in the need for dialysis among a prospectively-defined 
subgroup of patients suffering from OARF but did not show a significant 
reduction in mortality among this subgroup.

   AURICULIN anaritide had originally been developed as a treatment for the 
broad population of ARF patients and its failure in the ARF-Phase III trial 
has had a material adverse effect on the market price of the Company's Common 
Stock. Should AURICULIN anaritide fail to show a significant reduction in the 
need for dialysis among, or the mortality rate of patients suffering from 
OARF in the OARF-Phase III trial, such failure could have a similar material 
adverse effect on the Company's Common Stock.  There can be no assurance that 
AURICULIN anaritide will show a significant reduction in the need for 
dialysis among, or the mortality rate of, patients suffering from OARF.

DEPENDENCE ON THIRD PARTIES

   The Company plans to continue the development of therapies for the 
treatment of chronic conditions primarily under the sponsorship of corporate 
partners.  Continued funding and participation by the Company's corporate 
partners under joint development and licensing agreements will depend not 
only on the timely achievement of research and development objectives by the 
Company, which cannot be assured, but also on each corporate partner's own 
financial, competitive, marketing and strategic considerations.  Scios also 
may from time to time enter into collaborative arrangements involving the 
licensing of certain rights to its acute care therapeutics.  See "Risk 
Factors-Relationship with Genentech."  Under several of its joint 
development and license agreements, Scios relies on its corporate partners to 
conduct preclinical and clinical trials, to obtain regulatory approvals and 
to manufacture and market products. Although the Company believes that its 
corporate partners will have an economic incentive to meet their contractual 
responsibilities, the amount and timing of resources devoted to these 
activities generally will be controlled by the corporate partners.  
Suspension or termination of its joint development agreements with 


                                       6
<PAGE>

certain of Scios's corporate partners or the failure of those partners to 
meet their contractual responsibilities could have a material adverse effect 
on the Company.

   It is expected that, for at least the next several years, a portion of 
Scios's total revenues will continue to be derived from collaborative 
research agreements.  Future collaborative research agreements entered into 
by Scios, if any, may be subject to similar risks to those described in the 
preceding paragraph.  The inability of Scios to obtain new collaborative 
research agreements or to retain those currently in effect might have a 
material adverse effect on its future operations.

RELATIONSHIP WITH GENENTECH

   In December 1994 the Company entered into a Collaboration Agreement (the 
"Original Collaboration Agreement") with Genentech, Inc. relating to the 
joint development and commercialization of AURICULIN anaritide for use in the 
treatment of acute renal failure.  The Original Collaboration Agreement was 
amended in April 1996 to modify the timing of certain development timeframes 
and milestones.  Following the results of the ARF-Phase III clinical trials 
in May 1995, the focus of the Company's and Genentech's efforts under the 
Original Collaboration Agreement, as amended (the "Collaboration 
Agreement") has been the development and commercialization of AURICULIN 
anaritide for the treatment of OARF, a sub-category of ARF.  The 
Collaboration Agreement provides for co-promotion of AURICULIN anaritide in 
the United States and Canada and gives Genentech exclusive marketing rights 
in countries other than the United States and Canada (the "Licensed 
Territory").  In addition to royalties on sales in the Licensed Territory, 
Scios is to receive $30 million in milestone payments based upon regulatory 
filings or approvals in the U.S.  Under the Collaboration Agreement, the 
Company will receive $15 million upon the submission of a New Drug 
Application ("NDA") to the FDA to market AURICULIN, provided the submission 
takes places on or before June 30, 1998.  The remaining $15 million would be 
paid to the Company upon the earlier of sales exceeding $100 million in a 
twelve-month time period or January 1, 2001.  Genentech has the option to 
instead make a single $30 million payment upon FDA marketing approval if the 
submission of the NDA takes place after June 30, 1998.  Genentech may also be 
required to make additional payments of up to $20 million upon obtaining 
regulatory approvals and achieving certain sales levels in other designated 
markets.


   The Company will bear the development costs of AURICULIN anaritide until 
the receipt of regulatory approval in North America.  Thereafter, all costs 
of development and promotion within North America will be shared equally 
among the two parties.  Genentech will bear all costs for development and 
promotion within the Licensed Territory.

   For the reasons set forth in "Risk Factors-Government Regulation: Need 
for Regulatory Approval" there can be no assurance that the Company will 
ever receive the requisite regulatory approvals to market the product and to 
receive the milestone payments called for by the Collaboration Agreement.  In 
addition, for the reasons set forth in "Risk Factors-No Assurance of 
Successful and Timely Development and Approval of Products Under 
Development" and "-Uncertainty Regarding AURICULIN Anaritide" there can be 
no assurance that any product developed under the Collaboration Agreement 
will generate sufficient, if any, revenue (through milestone payments, sales, 
royalties, or otherwise) to offset the development and promotion costs 
incurred.

   Before the Company can file an NDA for AURICULIN anaritide, Phase III 
clinical trials must show significant clinical benefits in a given 
application. AURICULIN anaritide did not show significant clinical benefits 
in the treatment of the broad population of ARF patients in the ARF-Phase III 
clinical trials. The Company currently is conducting the OARF-Phase III 
clinical trials for the use of AURICULIN anaritide in the treatment of OARF.

   There can be no assurance that the OARF-Phase III clinical trials will 
show clinical benefits in the treatment of OARF or, if the OARF-Phase III 
clinical trials do show clinical benefits in the treatment of OARF, that the 
Company will be able to file an NDA before December 31, 1998.  If the Company 
does not file an NDA for AURICULIN anaritide by December 31, 1998, or if, 
within 60 days of such filing, the FDA has not accepted for review an NDA 
which was filed by December 31, 1998, Genentech has the option of (i) 
electing to bring


                                       7
<PAGE>

NATRECOR-Registered Trademark- BNP or another natriuretic peptide product 
under development by Scios into the Collaboration Agreement for use in the 
Field or (ii) terminating the Collaboration Agreement.  This option could 
limit the Company's ability to enter into other collaborative arrangements on 
NATRECOR BNP or any other natriuretic peptide product until the earlier of 
the FDA's acceptance for review of an NDA for AURICULIN anaritide or the 
expiration of the above deadlines.  If Genentech were to exercise its right 
to bring another product into the Collaboration Agreement in place of 
AURICULIN anaritide, the milestone payments due upon regulatory approval and 
other events would be reduced significantly.

RELIANCE ON CERTAIN PRODUCTS

   The Company currently markets in the United States four psychiatric 
products under license from SmithKline Beecham Corporation (the "SB 
Products") and co-promotes a fifth product, HALDOL-Registered Trademark- 
Decanoate distributed by McNeil Pharmaceutical ("McNeil").  As of June 1, 
1996, the Company will co-promote the antidepressant drug EFFEXOR-Registered 
Trademark-(venlafaxine HCl) under an agreement with the Wyeth-Ayerst 
Laboratories division of American Home Products ("WA").  The SB Products 
have a well-established reputation, but unit volume for certain products has 
been eroding and can be expected to continue to erode due to competition from 
generic products sold at substantially lower prices.  In the past, the 
decrease in unit sales has been partially offset by price increases; however, 
there can be no assurance that the market will accept any additional price 
increases.  Under its agreement with McNeil, the Company receives quarterly 
payments based on total sales of this product reaching specified levels.  
Although the Company believes that SmithKline Beecham ("SB"), WA and McNeil 
(collectively, the "Psychiatric Product Licensors") will have an economic 
incentive to meet their respective contractual responsibilities, the amount 
and timing of resources devoted to these activities generally will be 
controlled by such parties.  Suspension or termination of the Company's 
agreements with any Psychiatric Product Licensor or the failure of any 
Psychiatric Product Licensor to meet its contractual responsibilities could 
have a material adverse effect on the Company.

CONTINUING OPERATING LOSSES

   Scios has had net operating losses since its inception and expects such 
losses for at least several more years.  As of December 31, 1995, Scios had 
an accumulated deficit of approximately $290 million.

   The ability of the Company to achieve profitability depends principally 
upon the success of its product development efforts and the timing and scope 
of regulatory approvals, particularly with respect to the Company's lead 
products, AURICULIN anaritide and NATRECOR BNP.  Other key factors include 
the amount of profits generated from the Company's sale of the SB Products, 
HALDOL Decanoate and any additional products co-promoted or licensed by the 
Company and the development of new sources of third-party funding and other 
revenues to support continuing research and development programs.

NEED FOR ADDITIONAL FUNDING

   Substantial expenditures will be required to enable Scios to continue 
research and development activities, to conduct existing and planned clinical 
trials and to manufacture and market products currently under development. 
While Scios believes that its net assets, together with funding from 
corporate partners and interest income, will be sufficient to meet capital 
requirements through 1998, over the long term the Company will need to 
arrange additional financing for the operation of its business, including the 
commercialization of its products currently under development, and will 
consider collaborative arrangements and additional public or private 
financings, including additional equity financings.  There can be no 
assurances that such additional collaborative arrangements or financings can 
be obtained on reasonable terms.

DEPENDENCE ON PROPRIETARY RIGHTS OF OTHERS

   The manufacture and sale of any products developed by Scios will involve 
the use of processes, products or information the rights to certain of which 
are owned by others.  Although Scios has obtained licenses for the use of 
certain of such processes, products and information, there can be no 
assurance that such licenses will not be 


                                       8
<PAGE>


terminated or expire during critical periods, that Scios will be able to 
obtain licenses or other rights which may be important to it or, if obtained, 
that such licenses will be obtained on commercially reasonable terms.  If 
Scios is unable to obtain such licenses, it may have to develop alternatives 
to avoid infringing patents of others, potentially causing increased costs 
and delays in product development and introduction or precluding Scios from 
developing, manufacturing or selling its planned products.  Some of Scios's 
licenses provide for limited periods of exclusivity that may be extended only 
with the consent of the licensor.  There can be no assurance that extensions 
will be granted on any or all such licenses.  This same restriction may be 
contained in licenses obtained in the future.  Additionally, there can be no 
assurance that the patents underlying any licenses will be valid and 
enforceable.  To the extent any products developed by Scios are based on 
licensed technology, royalty payments on licenses will reduce Scios's gross 
profit from such product sales and may render the sales of such products 
uneconomical.

   Scios supports and collaborates in research conducted in universities and 
in governmental research organizations.  There can be no assurance that Scios 
will have or be able to acquire exclusive rights to inventions or technical 
information derived from such collaborations or that disputes will not arise 
as to rights in derivative or related research programs conducted by them.

   Scios receives grants and other public funding and collaborates with 
governmental research organizations in connection with certain research 
programs.  Inventions resulting from such public funding or collaboration may 
be subject to regulatory and contractual restrictions on the manner in which 
any resulting inventions may be commercialized, and the government research 
organization typically retains certain rights to use such inventions itself 
or, under certain circumstances, to grant rights to others.

   In the event of contractual breach or bankruptcy of Scios, certain of the 
Company's collaborative research contracts provide for transfer of technology 
(including rights to practice under any patents or patent applications) to 
the contract sponsors.

LIMITED MANUFACTURING EXPERIENCE

   Scios has concentrated its resources on product discovery and development 
prior to investing substantially in manufacturing capability. To date the 
Company has produced only its proprietary basic fibroblast growth factor 
("bFGF") in limited quantities sufficient for clinical trials then being 
conducted on bFGF and currently relies on third parties for the manufacture 
of other products including AURICULIN anaritide.  Scios has a production 
facility which the Company believes will enable it to produce bFGF for a 
third party, and potentially other products, under requirements for current 
Good Manufacturing Practices ("cGMP"). However, the Company does not 
currently possess the staff or facilities necessary to manufacture any 
product in the commercial quantity expected to be required in the long term. 
Scios's strategy of building or acquiring commercial-scale manufacturing 
facilities or utilizing third-party facilities only as the need arises 
carries with it certain risks, as there can be no assurance that such 
facilities can be built, acquired or used on commercially acceptable terms or 
at all or that Scios will be able to meet manufacturing quantity and quality 
requirements through the use of such arrangements.

   Scios currently intends to obtain AURICULIN anaritide from third-party 
manufacturers.  The Company has entered into a long-term agreement for the 
supply of AURICULIN anaritide in bulk form, and has entered into an agreement 
with another third party for fill and finish services. The Company believes 
that it would not be cost-effective to qualify alternate suppliers at this 
time. However, an inability of either the Company's bulk or its fill and 
finish manufacturer to provide material to Scios on a timely basis would 
cause delays in supply which could be expected to have a material adverse 
effect on the Company's business.

   SB manufactures the SB Products.  If SB elects to discontinue 
manufacturing the SB Products, the Company will either have to develop 
additional facilities to manufacture independently on a large scale, procure 
a contract manufacturer, or enter into another arrangement with a third party 
to manufacture such products. McNeil manufactures HALDOL Decanoate.


                                       9
<PAGE>

   If Scios were to develop additional products with commercial potential, it 
would be required to design and construct larger facilities to manufacture 
such products or be dependent upon securing a third party contract 
manufacturer to manufacture such products.  There can be no assurance that 
the Company would be able to develop such a manufacturing capability on its 
own or enter into such a partnership on favorable terms or at all.  In 
addition, partnering arrangements could result in a lower level of income to 
Scios than if the Company manufactured the products entirely on its own.

LACK OF MARKETING EXPERIENCE; DEPENDENCE ON THIRD PARTIES

   Scios has limited experience in managing or operating a marketing 
organization.  Scios currently has a sales force of approximately 85 
representatives experienced in marketing products to the psychiatric 
profession. These sales representatives work on a part-time basis marketing 
the SB Products and co-promoting the McNeil product HALDOL Decanoate.  To 
date, Scios's marketing experience has been limited to these psychiatric 
products.  The Company has had no experience marketing the acute care 
products which are the focus of its research and development efforts.

   Scios's business strategy includes acquiring or licensing additional 
products developed by third parties that could be sold by the Company's sales 
force while the Company seeks to complete clinical trials and 
commercialization of its proprietary products.  There can be no assurances 
that such third-party product rights will be available on terms favorable to 
the Company or at all, or that the Company will be successful in 
commercializing its own proprietary products.

   If Scios is successful in its efforts to develop additional products for 
commercial sale, the commercialization of such products will require 
significant financial resources as well as worldwide sales, marketing and 
distribution capabilities.  The Company will consider entering into 
additional corporate partnerships with major pharmaceutical companies in 
order to provide funds and expertise to meet these requirements.  See "Risk 
Factors-Relationship with Genentech."  There can be no assurance that the 
Company would be able to develop such a marketing capability on its own or 
enter into such a partnership on favorable terms or at all.  In addition, 
partnering arrangements could result in a lower level of income to Scios than 
if the Company marketed the products entirely on its own.

TECHNOLOGICAL CHANGE AND RISK OF OBSOLESCENCE; SUBSTANTIAL COMPETITION

   Competition is intense in the development of biopharmaceutical products, 
particularly in the development of products through the application of 
biotechnology.  There are numerous companies and academic research groups 
throughout the world engaged in similar research and development.  Some of 
the Company's competitors, including some of its licensees, are working on 
products similar to those being developed by Scios, including products in 
some of the Company's major therapeutic focus areas.  Many of these companies 
have substantially greater financial, marketing and human resources than 
Scios.  With respect to AURICULIN anaritide, Scios believes other companies 
may be attempting to develop other forms of natriuretic peptides for 
indications similar to those being pursued by the Company.

   There can be no assurance that technological developments or superior 
marketing capabilities possessed by competitors will not materially adversely 
affect the commercial potential of the Company's products. In addition, if 
the Company commences significant commercial sales of products, manufacturing 
efficiency and marketing capability are likely to be significant competitive 
factors. With respect to products no longer covered by patents, such as the 
SB Products, Scios faces competition from companies offering generic products.

   The Company believes that the competitive success of the Company will be 
based primarily on scientific and technological superiority, managerial 
competence in identifying and pursuing opportunities, operational competence 
in developing, protecting, producing and marketing products and obtaining 
timely regulatory agency approvals and adequate funds. Achieving success in 
these areas will depend on the Company's ability to attract and retain 
skilled and experienced personnel, to develop and secure the rights to 
advanced proprietary technology and 


                                      10
<PAGE>

to exploit commercially its technology prior to the development of 
competitive products by others.  Scios expects that there will be continued 
competition for highly qualified scientific, technical and managerial 
personnel.

UNCERTAINTY OF LEGAL PROTECTION AFFORDED BY PATENTS AND PROPRIETARY RIGHTS;
POSSIBLE INFRINGEMENT OF RIGHTS OF OTHERS

   Scios's success will depend in large part upon its ability to protect its 
proprietary products and technology under U.S.  and foreign patent laws and 
other intellectual property laws.  Scios has incurred and expects to continue 
to incur, substantial costs in connection with the protection of its 
intellectual property rights.  The patent position of biotechnology and 
pharmaceutical firms generally is highly uncertain and involves complex legal 
and factual questions. Although Scios believes it has strong patent positions 
on certain of its products, there can be no assurance that any patent will 
issue on pending applications of the Company, or that any patent issued will 
afford the Company significant commercial protection against competitors for 
the technology or product covered by it, or that patents will not be 
infringed upon or designed around.  Third parties have filed applications 
for, or have been issued patents relating to, products or processes which are 
similar to or competitive with certain of the Company's products or 
processes.  Scios is incurring and expects to continue to incur substantial 
costs in interference proceedings and in defending the validity or scope of 
its patents or in challenging the validity or scope of competing patents.  
The Company is unable to predict how the courts will resolve issues relating 
to the validity and scope of such patents, and if any such patent were to be 
interpreted to cover any of the Company's products and could not be licensed, 
circumvented or shown to be invalid, the results of Scios's future operations 
could be materially and adversely affected.

   Companies which have or obtain patents relating to Scios's products or 
processes could bring legal actions against Scios and its corporate partner 
claiming damages and seeking to enjoin them from manufacturing or marketing 
such products.  Because of such proceedings, Scios could encounter delays in 
product market introductions while it attempts to design around such patents 
or could find that the development, manufacture or sale of Scios's products 
could be foreclosed.  If any such action were successful, in addition to any 
potential liability for damages, Scios or its corporate partners could be 
required to obtain a license in order to continue to manufacture or market 
such products. Even if licenses were to be available, their cost might not be 
commercially acceptable.  If a patent were to be issued to a third party 
covering products competitive with Scios's products and such patent could not 
be licensed, circumvented or shown to be invalid, the results of Scios's 
future operations could be materially adversely affected.

   Scios also may have to participate in interference proceedings declared by 
the United States Patent and Trademark Office (the "PTO") to determine the 
priority of inventions, which could result in substantial cost to Scios or in 
the determination that patents should be issued to a competitor.  Unfavorable 
outcomes in interference proceedings could result in the need for 
cross-licensing agreements with competitors that could hinder or prevent 
Scios from making, using or selling the products which are the subjects of 
such patents or adversely affect Scios's operating results.

   Other companies engaged in research and development of new health care 
products based on biotechnology also are actively pursuing patents for their 
technologies, which they consider to be novel and patentable.  Scios also 
relies and will continue to rely upon trade secrets and know-how to develop 
and maintain its competitive position.  There can be no assurance, however, 
that others will not develop similar technology so that confidentiality 
agreements on which the Company relies to protect trade secrets will be 
honored.  To the extent corporate partners or consultants apply technological 
information independently developed by them or by others to Scios projects, 
disputes may arise as to the proprietary rights to such information.

GOVERNMENT REGULATION: NEED FOR REGULATORY APPROVAL

The production and marketing of the Company's proposed products and its 
ongoing research and development activities are subject to extensive 
regulation by numerous governmental authorities in the United States and 
other countries. Prior to marketing in the United States, a drug must undergo 
rigorous preclinical and clinical 


                                      11
<PAGE>

testing and an extensive regulatory approval process implemented by the U.S. 
Food and Drug Administration ("FDA") under federal law, including the Food, 
Drug and Cosmetic Act, as amended. Satisfaction of such regulatory 
requirements includes satisfying the FDA that the product is both safe and 
efficacious. Typically, this takes several years or more depending upon the 
type, complexity and novelty of the product and the nature of the disease or 
other indication to be treated and requires the expenditure of substantial 
resources.  Preclinical studies must be conducted in conformance with the 
FDA's Good Laboratory Practice regulations.  Clinical testing must meet 
requirements for Institutional Review Board ("IRB") oversight and informed 
consent by clinical trial subjects, as well as FDA prior review, oversight 
and the FDA's Good Clinical practice requirements.  Clinical trials may 
require large numbers of test subjects.  Scios has limited experience in 
conducting clinical testing and in pursuing applications necessary to gain 
regulatory approvals. Furthermore, the Company or the FDA may suspend 
clinical trials at any time if either believes that the subjects 
participating in such trials are being exposed to unacceptable health risks, 
including undesirable or unintended side effects.

   Before receiving FDA approval to market a product, Scios may have to 
demonstrate that the product is safe and effective on the patient population 
that will be treated.  Data obtained from preclinical and clinical activities 
are susceptible to varying interpretations which could delay, limit or 
prevent regulatory clearances. In addition, delays or rejections may be 
encountered based upon additional government regulation from future 
legislation or administrative action or changes in FDA policy during the 
period of product development, clinical trials and FDA regulatory review.  
Delays in obtaining such approvals could adversely affect marketing of 
Scios's products.  Delays in regulatory approvals that may be encountered by 
Scios's joint development partners and licensees could adversely affect 
Scios's ability to receive royalties or other sales revenues.  There can be 
no assurance that, after such time and expenditures, regulatory approval will 
be obtained for any products developed by the Company.  For example, after 
significant investment in the development of AURICULIN anaritide for the 
treatment of ARF, the ARF-Phase III clinical trial did not show the requisite 
clinical benefits to receive FDA approval for the use of AURICULIN anaritide 
in the treatment of the broad population of ARF patients.  And, while the 
Company is conducting Phase III clinical trials for the use of AURICULIN 
anaritide in the treatment of OARF, there can be no assurance that such Phase 
III trials will be successful.  Even if regulatory approval of a product is 
granted, such approval will be limited to those disease states and conditions 
for which the product is useful, as demonstrated through clinical studies.  
Marketing or promoting a drug for an unapproved indication is prohibited.  
For example, if the current OARF-Phase III trials show significant clinical 
benefits in the use of AURICULIN anaritide-Registered Trademark- for the 
treatment of OARF, FDA approval that might be obtained based upon such 
results would be limited to the treatment of OARF (a significantly smaller 
population than the treatment of ARF in the broad population).  See 
"Uncertainty Regarding AURICULIN Anaritide."

   Even after initial FDA approval has been obtained, for a product or 
treatment, further studies may be required to provide additional data on 
safety or to gain approval for the use of a product as a treatment for 
clinical indications other than those initially targeted.  Moreover, the FDA 
may reconsider its approval of any product at any time and may withdraw such 
approval.  Furthermore, approval may entail ongoing requirements for 
post-marketing studies.  If regulatory approval is obtained, a marketed 
product, its manufacturer and its manufacturing facilities are subject to 
continual review and periodic inspections.  The regulatory standards for 
manufacturing are currently being applied stringently by the FDA.  Discovery 
of previously unknown problems with a product, manufacturer or facility may 
result in restrictions on such product or manufacturer, including withdrawal 
of the product from the market.  In addition, before the Company's products 
can be marketed in foreign countries, they are subject to regulatory approval 
in such countries similar to that required in the United States.

   The Orphan Drug Act currently provides incentives to manufacturers to 
develop and market drugs for rare diseases, conditions affecting fewer than 
200,000 persons in the United States at the time of application for orphan 
drug designation, or conditions affecting more than 200,000 persons in the 
United States, if the sponsor establishes that it does not realistically 
anticipate that its product sales will be sufficient to recover its costs.  A 
drug that receives orphan drug designation and is the first product to 
receive FDA marketing approval for its product claim is entitled to a 
seven-year exclusive marketing period in the United States for that product 
claim.  However, a drug that is considered by the FDA to be different from a 
particular orphan drug is not barred from sale in the United States during 
the seven-year exclusive marketing period.  The Company has received from the 
FDA orphan drug 


                                      12
<PAGE>

designation of AURICULIN anaritide for the treatment of acute kidney failure; 
however, there can be no assurance that AURICULIN anaritide will receive FDA 
approval, or that, if it receives approval, it will receive exclusive 
marketing rights. Additionally, though it is advantageous to obtain orphan 
drug act designation for eligible products, there can be no assurance that 
the precise scope of protection that is currently afforded by orphan drug 
designation will be available in the future or that the current level of 
exclusivity and tax credits afforded to a sponsor of a product designated an 
orphan drug will remain in effect.

   The FDA's regulations require that any drug or formulation to be tested in 
humans must be manufactured according to cGMP regulations.  This has been 
extended to include any drugs which will be tested for safety in animals, in 
support of human testing.  The cGMPs set certain minimum requirements for 
procedures, record-keeping and the physical characteristics of the 
laboratories used in the production of these drugs.  In addition, various 
federal and state laws, regulations and recommendations relating to safe 
working conditions, laboratory practices, the experimental use of animals and 
the purchase, storage, movement, import and export, use, and disposal of 
hazardous or potentially hazardous substances, including radioactive 
compounds and infectious disease agents, used in connection with the 
Company's research work are or may be applicable to their activities.  They 
include, among others, the United States Atomic Energy Act, the Clean Air 
Act, the Clean Water Act, the Occupational Safety and Health Act, the 
National Environmental Policy Act, the Toxic Substances Control Act, and the 
Resource Conservation and Recovery Act, national restrictions on technology 
transfer, import, export and customs regulations, and other present and 
possible future local, state or federal regulation.  Scios is unable to 
estimate the extent and impact of regulation in the biotechnology field 
resulting from such future federal, state or local legislation or 
administrative action.

   Outside the United States, the Company's ability to market a product is 
contingent upon receiving marketing authorization from the appropriate 
foreign regulatory authorities. The requirements governing the conduct of 
clinical trials, marketing authorization, pricing and reimbursement vary 
widely from country to country. This foreign regulatory approval process 
includes all of the risks associated with FDA approval set forth above.

RISK OF PRODUCT LIABILITY

   The testing, marketing and sale of human therapeutic products entails 
significant risks. If the Company succeeds in developing products in these 
areas, use of such products in trials and the sale of such products following 
regulatory approval may expose the Company to liability claims allegedly 
resulting from use of such products.  These claims might be made directly by 
consumers or others.  Scios currently has only limited insurance for its 
clinical trials.   However, there can be no assurance that Scios will be able 
to obtain and maintain such insurance for all of its clinical trials or that 
coverage will be in sufficient amounts to protect against damages for 
liability that could have a material adverse effect on Scios.  There can also 
be no assurance that Scios will be able to obtain or maintain product 
liability insurance in the future on acceptable terms or in sufficient 
amounts to protect the Company against damages for liability that could have 
a material adverse effect on the Company.  The Company's agreements with SB 
and McNeil provide for certain indemnification, but there can be no assurance 
that any claim arising from products manufactured by SB or McNeil would not 
also include claims directly against Scios.

USE OF HAZARDOUS MATERIALS; RECENT NOTICE OF POTENTIAL LIABILITY

   In addition, the Company's research and development involves the 
controlled use of hazardous materials, radioactive compounds and other 
chemicals. Accordingly, the Company is subject to various federal, state and 
local environmental laws and regulations.  Failure to comply with present or 
future regulations could result in substantial liability to the Company, 
suspension or cessation of the Company's operations, restrictions on the 
Company's ability to expand at its present location or the incurrence of 
other significant expense. Although the Company believes that its safety 
procedures for handling and disposing of such materials comply with the 
standards prescribed by federal, state and local regulations, the risk of 
accidental contamination or injury from these materials cannot be completely 
eliminated. For example, on November 29, 1995, the Company was notified by 
the United States Environmental Protection Agency that it may have liability 
in connection with the clean-up of toxic waste arising out of the alleged 
disposal of hazardous substances by a subcontractor of Nova.  (The Company 
acquired Nova in 1992.)  The


                                      13
<PAGE>

Company could be held liable for any damages that result from such clean-up.  
The cost of this clean-up and any other potential environmental liability 
could exceed the resources of the Company. The Company may also incur 
substantial costs to comply with environmental regulations if the Company 
develops additional manufacturing capacity or otherwise changes its 
operations.  For example, in connection with the closure of its Baltimore 
research and development facility in 1993 to consolidate such activities at 
its Mountain View headquarters, the Company incurred costs of approximately 
$370,000 for chemical disposal, storage and related costs.

HEALTHCARE REIMBURSEMENT

   The business and financial condition of pharmaceutical and biotechnology 
companies will continue to be affected by the efforts of governmental and 
third-party payors to contain or reduce the cost of health care.  In certain 
foreign markets, pricing of profitability of prescription pharmaceuticals is 
subject to governmental control.  In the United States there have been, and 
the Company expects that there will continue to be, a number of federal and 
state proposals to implement similar government control.  In addition, an 
increasing emphasis on managed care in the United States has increased and 
will continue to increase the pressure on pharmaceutical pricing.  While the 
Company cannot predict whether any such legislative or regulatory proposals 
will be adopted or the effect such proposals or managed care efforts may have 
on its business, the announcement of such proposals or efforts could have a 
material adverse effect on the Company's ability to raise capital, and the 
adoption of such proposals or efforts could have a material adverse effect on 
the Company's business and financial condition.  Further, to the extent that 
such proposals or efforts have a material adverse effect on other 
pharmaceutical companies that are prospective corporate partners for the 
Company, the Company's ability to establish a strategic collaboration may be 
adversely affected.  In addition, in both domestic and foreign markets, sales 
of the Company's proposed products will depend in part on the availability of 
reimbursement from third-party payors such as government health 
administration authorities, private health insurers, and other organizations. 
Third-party payors are increasingly challenging the price and 
cost-effectiveness of medical products and services.  Significant uncertainty 
exists as to the reimbursement status of newly approved health care products. 
There can be no assurance that the Company's proposed products will be 
considered cost effective or that adequate third-party reimbursement will be 
available to enable the Company to maintain price levels sufficient to 
realize an appropriate return on its investment in product development.

NO ASSURANCE OF ABILITY TO ATTRACT AND RETAIN KEY PERSONNEL; ABSENCE OF KEY-MAN
LIFE INSURANCE

   Scios's ability to maintain its competitive technological position will 
depend, in part, upon its ability to attract and retain highly qualified 
scientific, managerial and manufacturing personnel.  Competition for such 
personnel is intense.  Scios must recruit and organize expanded marketing and 
sales organizations for those products it will commercialize directly.  The 
loss of a significant group of key personnel would adversely affect Scios's 
product development effort.  Scios does not currently maintain key-man life 
insurance on any of its employees.

VOLATILITY OF STOCK PRICE

   The market prices for securities of biotechnology and pharmaceutical 
companies, including the securities of Scios, have been volatile.  
Announcements of technological innovations or new commercial products by 
Scios or its competitors, a change in status of a corporate partner, 
developments concerning proprietary rights, including patents and litigation 
matters, publicity regarding actual or potential medical results with 
products under development by Scios, regulatory developments in both the 
United States and foreign countries and public concern as to the safety of 
biotechnology or of pharmaceutical products, as well as period-to-period 
fluctuations in revenues and financial results, may have a significant impact 
on the market price of its Common Stock. For example, the average trading 
price of Scios' Common Stock in the one-month period immediately preceding 
the release by Scios of the results of the ARF-Phase III to the public in May 
1995, was approximately 100% higher than the average trading price of such 
stock in the one-month period immediately following such release.  Any 
unfavorable releases in the future relating to other clinical trials, such as 
the OARF-Phase III trials, could have a similar depressive effect on the 
market price of the Scios Common Stock.

ABSENCE OF DIVIDENDS

   Scios has not paid any cash dividends since its inception, and it does not 
anticipate paying cash dividends in the foreseeable future.

ANTI-TAKEOVER EFFECTS OF CERTAIN PROVISIONS OF THE COMPANY'S CERTIFICATE OF
INCORPORATION AND BYLAWS

   Certain provisions of Scios's Certificate of Incorporation, as amended, 
Bylaws and Share Purchase Rights Plan may have the effect of delaying, 
deferring or preventing attempts to acquire control of Scios.  The delay, 
deferral or prevention of a change in control may result in denying to 
stockholders of Scios the receipt of a premium for their stock in the 
transaction which would have resulted in the change of control and may also 
result in a depressive effect on the market price of the Scios Common Stock.

                                USE OF PROCEEDS

   The Company will not receive any proceeds from the sale of Common Stock by 
the Selling Stockholder in the offering.

                              SELLING STOCKHOLDER

   The following table sets forth the name of the Selling Stockholder, the 
number of shares of Common Stock owned beneficially by the Selling 
Stockholder as of December 31, 1995 and the number of shares which may be 
offered pursuant to this Prospectus.  This information is based upon 
information provided by the Selling Stockholder.  Because the Selling 
Stockholder may offer all, some or none of its Common Stock, no definitive 
estimate as to the number of shares thereof that will be held by the Selling 
Stockholder after such offering can be provided.

(1)  Assumes the sale of all shares offered hereby.
(2)  Applicable percentage of ownership is based on 35,807,949 shares of Common
     Stock outstanding (net of treasury shares) on March 31, 1996 and assumes
     the issuance of 1,263,200 shares of Common Stock issuable upon conversion
     of 12,632 shares of the Company's Nonvoting Series A Preferred Stock.

   In December 1994 the Selling Stockholder entered into the Collaboration 
Agreement with the Company.  See "Risk Factors -- Relationship with 
Genentech." At that time the Selling Stockholder also (i) purchased $20 
million of Series A Preferred Stock of the Company convertible into 2,105,300 
shares of Common Stock and (ii) agreed to loan the Company an additional $30 
million, which the Company can draw down at its discretion through December 
2002 (the "Loan Facility"). Amounts drawn under the Loan Facility will bear 
interest at the prime rate and be repayable in cash or Scios Common Stock, at 
the Company's option, in December 2002.

   From March 31 to April 10, 1995, the Selling Stockholder converted 5,000 
shares of the Scios' Nonvoting Series A Preferred Stock into 500,000 shares 
of Common Stock and sold such shares to the public pursuant to a Registration 
Statement on Form S-3 filed by the Company in December 1994.  In January 
1996, the Selling Stockholder converted an additional 3,421 shares of the 
Scios' Nonvoting Series A Preferred Stock into 342,100 shares of Common Stock 
and sold such shares to the public pursuant to such Registration Statement.

                             PLAN OF DISTRIBUTION

   The Company is registering the shares of Common Stock offered by the 
Selling Stockholder hereunder pursuant to contractual registration rights 
contained in a Preferred Stock Purchase Agreement entered into in December 
1994 (the "Purchase Agreement"), pursuant to which the Selling Stockholder 
purchased 21,053 shares of nonvoting Series A Preferred Stock for 
approximately $20 million.  The Selling Stockholder currently owns 12,632 
shares of Series A. Each share of such Preferred Stock is convertible, at the 
request of the Selling Stockholder or upon transfer to a third party, into 
100 shares of the Company's Common Stock for a total of 1,263,200 shares of 
Common Stock.  The Selling Stockholder may not transfer ownership of any of 
such shares without first offering the Company the opportunity to purchase 
such shares at the average closing trading price for a period preceding the 
sale.  If the Company does not purchase the shares offered to it, the Selling 
Stockholder may sell such shares to any third party without reoffering them 
to the Company.  Furthermore, the Purchase Agreement provides that the 
Selling Stockholder may not, without the consent of Scios, sell to a single 
third party investor in any 12 month period more than 500,000 shares of 
Common Stock purchased under the Purchase Agreement prior to December 31, 
1996 or more than 1,000,000 shares of Common Stock during any 12 month period 
thereafter (except that the foregoing volume limitation is inapplicable to 
sales of the Common Stock to brokers or dealers who agree to abide by such 
volume limitation).  The foregoing transfer restrictions terminate upon the 
earliest to occur of (i) December 30, 2002, (ii) the date on which the 
Selling Stockholder and its affiliates no longer own 3% of the Company's 
outstanding voting securities or (iii) the closing of a merger or similar 
transaction in which greater than 50% of the Company's voting stock is 
transferred to a stockholder or group of stockholders, or a sale of all or 
substantially all of the Company's assets.

   Subject to the restrictions set forth in the Purchase Agreement, the 
shares of Common Stock offered hereunder may be sold from time to time by the 
Selling Stockholder, or by pledgees, donees, transferees or other successors 
in interest.  Such sales may be made on the Nasdaq National Market or in the 
over-the-counter market or otherwise, at prices and on terms then prevailing 
or related to the then-current market price, or in negotiated transactions.  
The shares of Common Stock may be sold to or through one or more 
broker-dealers, acting as agent or principal, in underwritten offerings, 
block trades, agency placements, exchange distributions, brokerage 
transactions or otherwise, or in any combination of transactions.

   In connection with distributions of the Common Stock, the Selling 
Stockholder may enter into hedging transactions with broker-dealers and the 
broker-dealers may engage in short sales of the Common Stock in the course of 
hedging the positions they assume with the Selling Stockholder.  The Selling 
Stockholder also may sell the Common Stock short and deliver the Common Stock 
to close out such short positions.  The Selling Stockholder also may enter 
into option or other transactions with broker-dealers that involve the 
delivery of the Common Stock to the broker-dealers, which may then resell or 
otherwise transfer such Common Stock.  The Selling Stockholder also may loan 
or pledge the Common Stock to a broker-dealer and the broker-dealer may sell 
the Common Stock so loaned or upon a default may sell or otherwise transfer 
the pledged Common Stock.

   In connection with any transaction involving the Common Stock, 
broker-dealers or others may receive from the Selling Stockholder, and may in 
turn pay to other broker-dealers or others, compensation in the form of 
commissions, discounts or concessions in amounts to be negotiated at the 
time.  Broker-dealers and any other persons participating in a distribution 
of the Common Stock may be deemed to be "underwriters" within the meaning 
of the Act in connection with such distribution, and any such commissions, 
discounts or concessions may be deemed to be underwriting discounts or 
commissions under the Act.

   Any or all of the sales or other transactions involving the Common Stock 
described above, whether effected by the Selling Stockholder, any 
broker-dealer or others, may be made pursuant to this prospectus.  In 
addition, any shares of Common Stock that qualify for sale pursuant to Rule 
144 under the Act may be sold under Rule 144 rather than pursuant to this 
prospectus.


                                      17
<PAGE>

   In order to comply with the securities laws of certain states, if 
applicable, the Common Stock may be sold in such jurisdictions only through 
registered or licensed brokers or dealers.  In addition, in certain states 
the Common Stock may not be sold unless it has been registered or qualified 
for sale or an exemption from registration or qualification requirements is 
available and is complied with.

   The registration fee and fees in connection with listing the Common Stock 
on the Nasdaq National Market will be reimbursed by the Selling Stockholder. 
The Selling Stockholder will also reimburse the Company for all other costs, 
expenses and fees in connection with the registration of the Common Stock 
with the Commission up to $20,000.  The Company and the Selling Stockholder 
have agreed, and hereafter may further agree, to indemnify certain persons, 
including broker-dealers or others, against certain liabilities in connection 
with any offering of the Common Stock, including liabilities arising under 
the Act.

                              LEGAL MATTERS

   The validity of the Common Stock offered hereby will be passed upon for 
the Company by Cooley Godward Castro Huddleson & Tatum, Palo Alto, California.

                  AMENDMENT NO. 1 TO COLLABORATION AGREEMENT

     THIS AMENDMENT NO. 1 TO COLLABORATION AGREEMENT, dated as of April 10, 
1996 (this "Amendment"), is entered into between SCIOS INC. (formerly Scios 
Nova Inc.), a Delaware corporation ("Scios" or "Scios Nova"), and GENENTECH, 
INC., a Delaware corporation ("Genentech").

                                 WITNESSETH:

     WHEREAS, Scios and Genentech have heretofore entered into a 
Collaboration Agreement dated as of December 30, 1994 (the "Collaboration 
Agreement");

     WHEREAS, Scios and Genentech desire to amend the Collaboration Agreement 
as hereinafter provided; and

     WHEREAS, capitalized terms not defined herein shall have the meanings 
given them in the Collaboration Agreement.

                                   AGREEMENT:

     NOW, THEREFORE, for good and valuable consideration, the receipt and 
adequacy of which are hereby acknowledged,  Scios and Genentech hereby agree 
as follows:

     SECTION 1.   AMENDMENT.  The Collaboration Agreement is hereby amended 
as follows:

     A.     Sections 2.2 through 2.4 are hereby amended in their entirety to 
read as follows:

     SECTION 2.2   AURICULIN NDA NOT FILED BY DECEMBER 31, 1998.  If, by 
December 31, 1998, Scios Nova has not filed an NDA for Auriculin for the 
treatment of acute renal failure or if within sixty (60) days of such filing 
the FDA has not accepted for review an NDA which was filed by December 31, 
1998, Genentech may, in its sole discretion, elect one of the following 
options:

   
            (i)     Genentech may elect to extend to [              *   ] the 
period of time  in which Scios Nova may file for purposes of Section 2.4 
below, an NDA for Auriculin for the treatment of acute renal failure;
    

            (ii)    Genentech may elect to cause Scios Nova to bring into the 
collaboration for the Field any other Scios Nova Product, or to bring into 
the collaboration for the Field any Genentech Product, and such Products(s) 
shall thereafter be a "Collaboration Product" for purposes of this Agreement; 
or

                                       1

<PAGE>

            (iii)   Genentech may elect to terminate this Agreement as 
provided in Section 15.2(b).

   
Such election must be made by Genentech within sixty (60) days of the later 
of (A) December 31, 1998 if Scios Nova has not filed an NDA for Auriculin by 
such date or (B) the date upon which Scios Nova notifies Genentech that the 
FDA has not accepted for review an NDA filed by December 31, 1998.  If no 
election is made prior to the end of such election period, this Agreement 
shall terminate automatically pursuant to Section 15.2(b).  In addition, 
Genentech's right to include Scios Nova Products hereunder shall terminate in

     SECTION 2.3   MUTUAL AGREEMENT TO TERMINATE AURICULIN DEVELOPMENT.  If 
the Parties mutually agree that the development of Auriculin in the Field 
should be discontinued prior to December 31, 1998, the Parties shall endeavor 
to select either a Scios Nova Product or a Genentech Product to be developed 
by Scios Nova as the first Collaboration Product.  If, within sixty (60) days 
of such decision to discontinue development of Auriculin, the Parties are not 
able to agree on another product to develop, then Genentech shall have the 
rights under Section 2.2.

   
     SECTION 2.4   AURICULIN NDA FILED BY DECEMBER 31, 1998.  If, by December 
31, 1998, Scios Nova has filed an NDA for Auriculin for the treatment of 
acute renal failure and the FDA has accepted such NDA for review within sixty 
(60) days of such filing, each Party shall thereafter have the right to 
require the other Party to contribute any or all of its Products, on a 
product-by-product basis, to the collaboration for use in the Field.  Upon 
the exercise of such right by the non-developing Party as to a Product of a 
developing Party, such Product shall become a Collaboration Product for all 
purposes of this Agreement.  Such right as to a Product may be exercised by 
providing written notice to the developing Party at any time after such FDA 
acceptance of an Auriculin NDA and prior to the Phase III Decision Date; 
PROVIDED, HOWEVER, that if Genentech has commenced Phase III trials of any 
Genentech Product in the Field prior to FDA acceptance of an NDA for 
Auriculin filed before December 31, 1998, Scios Nova shall have ninety (90) 
days from the date of such FDA acceptance within which to make the Product 
Election as to such first Genentech Product.  In addition, each Party's right 
to include the other Party's Products hereunder shall terminate in its 
entirety on [               *        ].

collaboration with respect to such Non-Natriuretic Product for use in the 
Field under this Agreement.  If, by[                                 ], Scios 
Nova has filed an NDA for Auriculin for the treatment of acute renal failure 
and the FDA has accepted such NDA for review within sixty (60) days of such 
filing, the Parties shall continue to be bound until [           *         ]

If, by December 31, 1998, Scios Nova has not filed such an NDA or if within 
sixty (60) days of such filing the FDA has not accepted for review an NDA 
which was filed by December 31, 1998, Scios Nova shall continue to be bound 
until [             *             ] to such obligation to first offer 
Genentech an opportunity to negotiate with Scios Nova a collaboration with 
respect to the use in the Field of any Scios Nova Non-Natriuretic Product

resolve such dispute in accordance with Section 17.1.  

     E.     The first sentence of Section 4.5(c) of the Collaboration 
Agreement is hereby amended in its entirety to read as follows:

            (d)     If the panel decides that there is not sufficient data to 
continue development of Auriculin, but determines that there is sufficient 
data suggesting that Natrecor should be developed as a product in the Field, 
Scios Nova shall thereafter develop Natrecor in the Field in the Co-Promotion 
Territory, in accordance with a Development Plan to be reviewed by the JDC 
and reviewed and approved by the Management Committee until the earlier of 
(i) the completion of a Phase II Clinical Trial (for the purposes of this
