CORP. AND ITS CONSOLIDATED SUBSIDIARIES.

                                  THE COMPANY

    Alliance  is a pharmaceutical research  and development company that focuses
on developing scientific discoveries into potential drug products and  licensing
these  products to multinational pharmaceutical  companies in exchange for fixed
payments and royalties. To  date, the Company has  entered into agreements  with
researchers  for the rights to two innovative products, developed these products
through  initial  clinical  (human)  trials,  and  entered  into   collaborative
relationships  with multinational pharmaceutical companies  for the final stages
of  development  and  worldwide  marketing.  These  products  are  OXYGENT,   an
intravascular  oxygen  carrier  designed  to reduce  the  need  for  donor blood
transfusions during surgery, which is currently in Phase IIb clinical trials and
is licensed to affiliates of Johnson & Johnson, and LIQUIVENT, an intrapulmonary
agent for use in treatment of acute respiratory failure, which is currently in a
pivotal Phase II/III clinical trial and  is licensed to Hoechst Marion  Roussel,
Inc., an affiliate of Hoechst AG. Alliance intends to enter into a collaborative
agreement  for IMAGENT  US, an ultrasound  contrast agent for  which the Company
expects to begin clinical trials in the near future.

    The Company's strategy is to identify potential new pharmaceutical  products
through   scientific   collaborations   with  researchers   and   clinicians  in
universities and medical centers where many  of the basic causes of disease  and
potential  targets for  new therapies  are discovered.  Using its  experience in
defining  pharmaceutical   formulations,  designing   manufacturing   processes,
conducting  preclinical  pharmacology  and  toxicology  studies,  and conducting
early-phase human testing, Alliance endeavors  to advance such discoveries  into
clinical  development.  The Company  seeks  collaborative relationships  for the
final stages of drug development, including completing late-phase human testing,
obtaining worldwide  regulatory  approvals, building  large-scale  manufacturing
capacities, and marketing.

    Alliance's products currently in clinical development -- OXYGENT, LIQUIVENT,
and  IMAGENT  US  --  are  based  upon  perfluorochemical  ("PFC")  and emulsion
technologies. PFCs are biochemically  inert compounds and may  be employed in  a
variety  of therapeutic and diagnostic  applications. The Company's primary drug
substance is  perflubron,  a brominated  PFC  that  has a  high  solubility  for
respiratory gases and can be used to transport these gases safely throughout the
body.

    OXYGENT,  an  emulsion  containing perflubron,  is  an  intravascular oxygen
carrier to  be used  as a  temporary  "blood substitute"  to provide  oxygen  to
tissues  during elective surgeries where  substantial blood loss is anticipated.
OXYGENT has several potential advantages  compared to allogeneic (donor)  blood:
there  is no risk of infectious disease  transmission, it is compatible with all
blood types,  it  has  a shelf-life  in  excess  of  one year,  and  it  can  be
sterilized.  OXYGENT can  be used  with autologous  blood collection techniques,
including predonation, hemodilution, and salvage, to enhance safety by  reducing
the need for allogeneic blood. OXYGENT is currently in Phase IIb clinical trials
with surgical patients at multiple sites in the United States and Europe.

    In  August 1994,  the Company entered  into a license  agreement (the "Ortho
License Agreement") with Ortho Biotech, Inc. and The R.W. Johnson Pharmaceutical
Research Institute, a division  of Ortho Pharmaceutical Corporation,  affiliates
of Johnson & Johnson (collectively referred to as "Ortho"), which provides Ortho
with  worldwide  marketing  rights  to the  Company's  injectable  PFC emulsions
capable of  transporting  oxygen for  therapeutic  use, including  OXYGENT.  The
product is being developed jointly by Alliance and Ortho, with Ortho responsible
for  substantially all of  the remaining costs of  development and marketing. In

                                       3
<PAGE>
conjunction with  the Ortho  License Agreement,  Johnson &  Johnson  Development
Corp. ("J&JDC") purchased equity securities of the Company for $15.0 million. In
addition,  Ortho paid  Alliance an  initial license  fee and  will pay milestone
payments and royalties on product sales.

    LIQUIVENT, sterile perflubron,  is an  intrapulmonary agent  to treat  acute
respiratory  failure, a  disorder that  can result  from many  causes, including
serious infection,  traumatic  shock,  severe burns,  and  inhalation  of  toxic
substances,  and is  characterized by  impairment of  normal lung  function. The
Company is conducting a  multi-center pivotal Phase  II/III clinical trial  with
LIQUIVENT  in pediatric  patients with  acute respiratory  failure, and separate
multi-center Phase  II  clinical trials  in  adults and  premature  infants  are
underway.  The U.S. Food  and Drug Administration ("FDA")  has granted Subpart E
status (expedited review) for the development of LIQUIVENT.

    In February 1996, the  Company entered into a  license agreement (the  "HMRI
License  Agreement" and, together with the Ortho License Agreement, the "License
Agreements") with Hoechst  Marion Roussel,  Inc. ("HMRI"),  which provides  HMRI
with  worldwide marketing rights to the intratracheal administration of liquids,
including LIQUIVENT, which perform bronchoalveolar lavage or liquid ventilation.
The  product  will  be  developed  jointly  by  Alliance  and  HMRI,  with  HMRI
responsible  for substantially  all of  the costs  of development  and marketing
after March  31, 1996.  In conjunction  with the  HMRI License  Agreement,  HMRI
agreed  to  purchase equity  securities  of the  Company  for $22.0  million. In
addition, HMRI will pay Alliance license fees, milestone payments, and royalties
on product sales. Closing of the transactions with HMRI is subject to expiration
or early termination  of the  waiting period under  the Hart-Scott-Rodino  Anti-
Trust  Improvements Act of 1976, as amended (the "HSR Act"), and other customary
conditions, all of  which are expected  to be satisfied  within the next  thirty
days. However, there can be no assurance that the transactions with HMRI will be
consummated.

    IMAGENT  US  is  a  PFC-based intravenous  ultrasound  contrast  agent being
developed to aid in the assessment of cardiac function and myocardial perfusion,
as well as  the detection of  solid organ lesions  and blood flow  abnormalities
caused  by vascular diseases. In preclinical  studies, this agent has been found
to enhance the signal from perfused tissues and blood vessels using  traditional
gray-scale  and color  Doppler technologies,  as well  as the  emerging harmonic
ultrasound  imaging  technique.   In  February  1996,   the  Company  filed   an
investigational  new drug application  ("IND") with the  FDA and clinical trials
are expected to begin in the near future.

    Alliance is assessing an apoptotic  factor for regulation of cancerous  cell
death  and  has ongoing  research activities  to exploit  its expertise  in PFC,
emulsion, and surfactant  technologies. In addition,  the Company is  evaluating
its  antigenized antibody technology  for use in  developing a prototype vaccine
for an infectious disease and a prototype tolerogen for an autoimmune disease.

                                  RISK FACTORS

    An  investment in the Common Stock offered  hereby involves a high degree of
risk. The  following  factors  and cautionary  statements  should  be  carefully
considered in evaluating the Company and its business:

    LIMITED PRODUCT REVENUES; HISTORY OF OPERATING LOSSES.  Substantially all of
the  Company's  revenues to  date have  consisted  of licensing  fees, milestone
payments, and payments to fund  research and development activities under  joint
development  and license  agreements. The Company  has had  net operating losses
since its inception and  expects such losses to  continue unless and until  such
time  as  revenues  are sufficient  to  fund  its continuing  operations.  As of
December 31, 1995, the Company had an accumulated deficit of $203.8 million,  of
which  approximately $35.5 million reflects  non-cash charges from the Company's
acquisition by merger of  Fluoromed Pharmaceutical, Inc.  on February 24,  1989.
There can be no assurance that the Company will be able to achieve profitability
at  all or on  a sustained basis.  See "Management's Discussion  and Analysis of
Financial Condition and Results of Operations."

    RELIANCE ON COLLABORATIVE PARTNERS; FUTURE COLLABORATIONS.  The Company  has
entered   into   the  License   Agreements  to   support  the   development  and
commercialization of OXYGENT and LIQUIVENT and to raise capital. Pursuant to the
License Agreements, the  Company has granted  significant licensing rights.  The
Company's  strategy is to seek additional  collaborations. However, there can be
no assurance that the Company will be able to negotiate acceptable collaborative
arrangements in the  future, or  that any  current or  future arrangements  will
ultimately  be successful. Under the License Agreements, the Company will depend
on Ortho  and  HMRI  for  development, regulatory  approval,  and  marketing  of
products.  The termination of either of  the License Agreements, which can occur
on at  least one  month's  advance notice,  or  any other  future  collaborative
arrangement  could  adversely  affect the  Company's  research,  development or,
ultimately, product distribution  plans. The Company's  revenues from  milestone
payments  or sales of any product will depend in large part upon the efforts and
abilities of the collaborative  partner to perform  clinical testing, to  obtain
regulatory  approvals, and to manufacture and market the product. The amount and
timing of resources devoted  to these activities will  not be completely  within
the Company's control. The collaborative partner will have certain discretion in
deciding  whether to commercialize  the product. There can  be no assurance that
the corporate interests and motivations of the Company's collaborative  partners
will remain consistent with those of the Company. See "Business -- Collaborative
Relationships."

    GOVERNMENT REGULATION; UNCERTAINTIES RELATED TO CLINICAL TRIAL RESULTS.  The
production  and  marketing  of  the  Company's  products  and  its  research and
development activities  are subject  to regulation  for safety  and efficacy  by
numerous  government  authorities  in  the United  States  and  other countries.
Clinical trials and the  manufacturing and marketing  of the Company's  products
are  subject  to  the  testing  and approval  process  of  the  FDA  and foreign
regulatory authorities. The  FDA and other  regulatory authorities require  that
the  safety and  efficacy of a  drug be  supported by results  from adequate and
well-controlled clinical  trials before  approval for  commercial sale.  If  the
results  of the clinical trials of the Company's products do not demonstrate the
safety and efficacy of the  products, the Company will not  be able to submit  a
New  Drug  Application ("NDA")  to the  FDA.  Even if  the Company  believes the
clinical trials demonstrate the  safety and efficacy of  a product, the FDA  and
other  regulatory authorities  may not  accept the  Company's assessment  of the
results. In either  case, the Company  may have to  conduct additional  clinical
trials  in an effort to demonstrate the  safety and efficacy of the product. The
process  of  obtaining  regulatory  clearances   or  approvals  is  costly   and
time-consuming.  The Company  cannot predict  how long  preclinical and clinical
trials will take or whether they will be successful, nor can the Company predict
how long the necessary regulatory approvals or clearances will take.  Therefore,
there  can be no  assurance that the  necessary clearances or  approvals will be
obtained, or  obtained  on  a  timely  basis.  Without  acceptable  results  and
regulatory  approval,  the  Company  would  not  be  able  to  commercialize its
products, which would have a material  adverse effect on the Company. There  can
be no assurance that the results of any of the Company's clinical trials will be
favorable  or that  the Company's products  will obtain  regulatory approval for
commercialization. The effect of governmental regulations which might arise from
future legislative or administrative action  cannot be predicted. See  "Business
- -- Government Regulation."

                                       6
<PAGE>
    UNCERTAINTY  OF DEVELOPMENT  AND COMMERCIALIZATION  EFFORTS.   The Company's
products  require   substantial  development   efforts.  The   Company  or   its
collaborative  partners  may  encounter unforeseen  technological  or scientific
problems, including side  effects, which  may force  abandonment or  substantial
change  in the  development of a  specific product or  process, or technological
change or  product developments  by others,  any of  which may  have a  material
adverse  effect  on  the  Company.  Further,  even  after  successful  technical
development and  receipt of  governmental approval,  a product  may not  achieve
commercial  success. To date,  the Company has  received regulatory approval for
the commercial sale of only  one of its drug products,  the sales of which  were
discontinued due to limited revenue potential.

    FUTURE  CAPITAL  NEEDS; UNCERTAINTY  OF ADDITIONAL  FINANCING.   The Company
believes that its existing capital  resources, including expected revenues  from
the  License Agreements and investments,  as well as the  net proceeds from this
offering and income  earned thereon,  will be  adequate to  satisfy its  capital
requirements  for at least the next 24  months. 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 continued
scientific progress  in its  research and  development programs,  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,  and marketing  arrangements, and the
cost of manufacturing  scale-up, if necessary.  No assurance can  be given  that
adequate  financing will be available  to the Company in  the future or on terms
acceptable to the Company.

    UNPREDICTABILITY OF PATENT PROTECTION; PROPRIETARY TECHNOLOGY.  The  Company
believes  that its  success will  depend largely  on its  ability to  obtain and
maintain patent protection for  its own inventions and  licenses for the use  of
patents  owned  by  third parties.  The  Company has  obtained  patents covering
certain intermediate and high  concentration PFC emulsions,  as well as  patents
related  to liquid ventilation. The Company has filed, and when appropriate will
file, other patent applications  with respect to its  products and processes  in
the  United States and in foreign countries. There can be no assurance, however,
that the Company will develop any additional products and processes which may be
patentable or that any  additional patents will be  issued. It is possible  that
patents  issued to  the Company or  any patents  licensed to the  Company may be
challenged successfully, that the Company may infringe patents of third  parties
unintentionally,  and  that  the  Company  may have  to  alter  its  products or
manufacturing processes  to take  into  account the  patents of  third  parties,
causing  delays  in product  development. Litigation,  which  could result  in a
substantial cost to the Company, may be necessary to enforce any patents  issued
to the Company and/or to determine the scope and validity of others' proprietary
rights.  The  Company  also attempts  to  protect its  proprietary  products and
processes by relying on trade secret laws and non-disclosure and confidentiality
agreements with its employees and certain  other persons who have access to  its
products  or processes. No assurance  can be given that  others will not develop
such products or processes  independently or obtain access  to such products  or
processes.  To  the extent  that others  develop or  obtain similar  products or
processes, the Company's  competitive position  may be  affected adversely.  See
"Business -- Patents."

    LIMITED MANUFACTURING CAPABILITY AND EXPERIENCE.  While the Company believes
that  it can produce materials for clinical trials and the initial market launch
for its emulsion products at its  existing San Diego facility and for  LIQUIVENT
at  its Otisville facility,  it may need to  expand its commercial manufacturing
capabilities for its products in the future. This expansion may occur in stages,
each of which  would require regulatory  approval, and product  demand could  at
times  exceed supply capacity. The  Company has not selected  a site or obtained
any regulatory approvals  for construction of  a commercial production  facility
for  its products, nor can there be any assurance that it will be able to do so.
The projected  location and  completion  date of  any production  facility  will
depend upon regulatory and development activities and other factors. The Company
cannot  predict the amount  that it will  expend for the  construction of such a
production facility, and there can be no assurance as to when or whether the FDA
will determine that  such facility complies  with Good Manufacturing  Practices.
Construction  of  a  facility  will  depend  on  regulatory  approvals,  product
development, and  capital  resources,  among other  things.  The  Ortho  License
Agreement  provides  an option  to Ortho  to elect  to manufacture  the emulsion
products referred to  therein, or  to require  the Company  to manufacture  such
products  at  a  negotiated  price.  The  HMRI  License  Agreement  requires the

                                       7
<PAGE>
Company to manufacture LIQUIVENT at its Otisville facility for a period of  time
after  market launch and to sell the product to HMRI at a negotiated price. HMRI
will be  responsible for  establishing production  capacity beyond  the  maximum
capacity of the Otisville facility. See "Business -- Manufacturing."

    UNCERTAINTY   OF  THIRD-PARTY  REIMBURSEMENT.    The  Company's  ability  to
commercialize its products  successfully will depend  in part on  the extent  to
which  appropriate reimbursement levels for the cost of the products and related
treatment are obtained from government authorities, private health insurers  and
other   organizations,  such  as   health  maintenance  organizations  ("HMOs").
Third-party payors are increasingly challenging  the prices charged for  medical
products  and services. Also, the trend  toward managed healthcare in the United
States, the growth of organizations such  as HMOs, and legislative proposals  to
reform   healthcare  and  government   insurance  programs  could  significantly
influence the purchase of healthcare  services and products, resulting in  lower
prices  and reducing  demand for  the Company's  products. The  cost containment
measures that healthcare  providers are  instituting and  any healthcare  reform
could  affect the Company's ability to sell its products and may have a material
adverse effect on the Company. There  can be no assurance that reimbursement  in
the  United  States  or foreign  countries  will  be available  for  any  of the
Company's products, that any reimbursement  granted will be maintained, or  that
limits  on reimbursement available  from third-party payors  will not reduce the
demand for,  or negatively  affect the  price of,  the Company's  products.  The
unavailability  or  inadequacy of  third-party  reimbursement for  the Company's
products would have  a material adverse  effect on the  Company. The Company  is
unable  to forecast  what additional legislation  or regulation  relating to the
healthcare industry or third-party coverage and reimbursement may be enacted  in
the  future, or  what effect  the legislation  or regulation  would have  on the
Company's business.

    DEPENDENCE  UPON  KEY  PERSONNEL.    The  Company's  success  in  developing
marketable  products and achieving a competitive  position will depend, in part,
on its  ability  to  attract  and retain  qualified  scientific  and  management
personnel.  Competition for such  personnel is intense, and  no assurance can be
given that  the Company  will be  able  to attract  and retain  such  personnel.
Scientific   advisors  to  the  Company  are  employed  by  or  have  consulting
arrangements with third parties which may conflict with their obligations to the
Company. The Company's anticipated growth and expansion will require  additional
expertise  and  are  expected  to  place  additional  demands  on  the Company's
management and financial resources.

    COMPETITION; RAPID TECHNOLOGICAL CHANGE.   Biotechnology and  pharmaceutical
companies  are  highly  competitive. There  are  many  pharmaceutical companies,
biotechnology  companies,  public   and  private   universities,  and   research
organizations  actively engaged in research and development of products that may
be similar to, or seek to attack the same targets as, Alliance's products.  Many
of  the Company's existing  or potential competitors  have substantially greater
financial, technical, and  human resources than  the Company and  may be  better
equipped  to  develop, manufacture,  and  market products.  These  companies may
develop and introduce  products and  processes competitive with  or superior  to
those  of  the  Company. In  addition,  other  technologies or  products  may be
developed that have an entirely different approach or means of accomplishing the
intended purposes of  the Company's  products which might  render the  Company's
technology  and products  uncompetitive or obsolete.  There can  be no assurance
that the  Company  will  be  able to  compete  successfully.  See  "Business  --
Competition."

    PRODUCT  LIABILITY CLAIMS AND  UNINSURED RISKS.   Products or processes that
may be developed, licensed,  or sold by  the Company may  expose the Company  to
potential  liability from  claims by end-users  of such products  or of products
manufactured by  such processes,  or  by manufacturers  or others  selling  such
products,  either  directly or  as a  component of  other products.  The Company
currently maintains limited product liability  insurance coverage. There can  be
no  assurance that the Company will be  able to maintain such coverage or obtain
additional coverage on  acceptable terms,  or that such  insurance will  provide
adequate coverage against all potential claims.

    VOLATILITY   OF   STOCK   PRICE;  LIQUIDATION   PREFERENCE;   AND   LACK  OF
DIVIDENDS.  The market prices for securities of biopharmaceutical companies have
historically been highly volatile. Announcements  concerning the Company or  its
competitors, including the results of testing and clinical trials, technological
innovations, or

                                       8
<PAGE>
commercial products, government regulations, developments concerning proprietary
rights,  including  patents and  litigation  matters, a  change  in status  of a
collaborative partner, public concern relating to the commercial value or safety
of the Company's  products, and stock  market conditions in  general may have  a
significant  impact on the price of the Common Stock. See "Price Range of Common
Stock."
    The Company has 1,500,000  shares of Series  A Preferred Stock  outstanding.
Such  preferred  stock is  entitled to  an annual  $0.50 per  share preferential
dividend, and  has  a liquidation  preference  of  $10.00 per  share,  plus  all
accumulated  but unpaid  dividends. Upon  consummation of  the transactions with
HMRI, the Company will have outstanding (i) 750,000 shares of Series B Preferred
Stock  entitled  to  an  annual  $1.00  per  share  preferred  dividend,  and  a
liquidation  preference of  $20.00 per  share, plus  all accumulated  but unpaid
dividends and (ii)  200,000 shares  of Series C  Preferred Stock  entitled to  a
liquidation preference of $.01 per share.

    The  Company has not paid dividends on  its Common Stock since its inception
and does  not  intend to  pay  any such  dividends  in the  foreseeable  future.
Further,  the Company in general is required  to pay cumulative dividends on its
outstanding preferred stock prior to paying  any dividends on its Common  Stock.
As  of December  31, 1995,  the Company  had recorded  as a  liability dividends
payable totalling $969,000  on the  Series A  Preferred Stock.  The Company  has
incurred  losses and,  thus, has  had a  deficiency in  preferred stock dividend
coverage. For the years ended June 30,  1991, 1992, 1993, 1994 and 1995 and  the
six months ended December 31, 1994 and 1995, the Company has incurred net losses
of  $17,702,000, $21,766,000, $26,380,000, $36,946,000, $29,717,000, $15,368,000
and $14,706,000, respectively.

    SHARES ELIGIBLE FOR FUTURE SALE.  As of December 31, 1995, 3,580,505  shares
of  Common Stock (or  13% of the total  number of shares  outstanding on a fully
diluted basis)  were  issuable upon  the  exercise of  outstanding  options  and
warrants  (excluding a warrant with respect  to 500,000 shares to be repurchased
by the Company). See "Use of Proceeds." Additional shares may be issued upon the
conversion of  preferred stock,  and  the Company  expects to  issue  additional
shares  of  preferred stock  and warrants  in  connection with  the contemplated
transactions with  HMRI described  elsewhere herein.  See "Capitalization."  The
existence  of  such warrants,  options and  convertible  securities, as  well as
certain registration rights, may adversely affect the terms on which the Company
may obtain additional equity financing. The holders of the outstanding  warrants
and  options are likely to exercise their  securities at a time when the Company
would otherwise be  able to obtain  capital on terms  more favorable than  those
provided by the exercise or conversion prices thereof.

    IMMEDIATE  AND  SUBSTANTIAL  DILUTION.    Investors  in  this  offering will
experience immediate  and substantial  dilution  in book  value per  share.  See
"Dilution."

    THE  CAUTIONARY STATEMENTS SET FORTH ABOVE  AND ELSEWHERE IN THIS PROSPECTUS
SHOULD BE READ AS ACCOMPANYING FORWARD-LOOKING STATEMENTS INCLUDED UNDER "USE OF
PROCEEDS," "MANAGEMENT'S  DISCUSSION AND  ANALYSIS  OF FINANCIAL  CONDITION  AND
RESULTS  OF  OPERATIONS"  AND  ELSEWHERE HEREIN.  THE  RISKS  DESCRIBED  IN SUCH
STATEMENTS COULD CAUSE  THE COMPANY'S  RESULTS TO DIFFER  MATERIALLY FROM  THOSE
EXPRESSED IN OR INDICATED BY SUCH FORWARD- LOOKING STATEMENTS.

                                USE OF PROCEEDS

    The  net  proceeds from  this offering  are estimated  to be  $42.2 million,
assuming a public offering price of $18 1/8 per share. The Company also  expects
to  receive more  than $22.0  million in  license fees  and for  the purchase of
equity securities  at the  closing of  the contemplated  transactions with  HMRI
described  elsewhere herein. Approximately $2.5 million  of the proceeds of this
offering will be used  to repurchase an outstanding  warrant to acquire  500,000
shares  of Common  Stock (the "Warrant  Repurchase"). The purchase  price of the
warrant is based upon the offering price of the Common Stock offered hereby. The
Company's agreement  with the  warrantholder provides  that the  warrantholder's
obligation to sell the warrant is subject to its receiving at least $1.5 million
in  the aggregate. If this condition is not satisfied and the warrantholder does
not sell the warrant to the Company, the Company will use the proceeds it  would
have otherwise used to purchase the warrant for the purposes set forth herein.

    The  remaining proceeds will be used  to fund research, preclinical testing,
and clinical  trials  for the  Company's  products, and  for  general  corporate
purposes.  In particular,  the Company expects  to devote  an increasingly large
amount of its  resources to  the clinical development  of IMAGENT  US, its  only
clinical-stage  product  not  presently subject  to  a  collaborative agreement.
Pending such  application,  the Company  intends  to deposit  such  proceeds  in
interest-bearing  bank  accounts or  to invest  them in  short-term, high-grade,
interest-bearing securities.  The  Company  believes  it  will  need  additional

can be given that adequate financing will be available to the Company. See "Risk

                                    DILUTION

    As  of  December 31,  1995,  the net  tangible  book value  of  the Company,
adjusted to include the purchase of equity securities by HMRI in connection with
the HMRI License Agreement, was approximately $42.5 million, or $1.58 per share.
"Net tangible book  value per  share" represents  the amount  of total  tangible
assets of the Company reduced by the total liabilities and divided by the number
of  shares of Common Stock outstanding (after giving effect to the conversion of
the outstanding shares of preferred stock  and of the shares of preferred  stock
expected  to be issued to HMRI into  Common Stock at an assumed conversion price
of $18 1/8 per share). After giving  effect to the sale of the 2,500,000  shares
of  Common Stock offered in this offering at an assumed public offering price of
$18 1/8 per share, the pro forma net tangible book value of the Common Stock  as
of  December 31, 1995 (after deducting  the underwriting discounts and estimated
expenses of this  offering and after  giving effect to  the Warrant  Repurchase)
would have been approximately $82.2 million, or $2.80 per share. This represents
an  immediate increase in net tangible book value of $1.22 per share to existing
shareholders and an  immediate dilution  of $15.33  per share  to new  investors
purchasing  shares  of  Common  Stock in  this  offering.  "Dilution  per share"
represents the difference between  the price per share  of Common Stock paid  by
the  new investors in this offering and the net tangible book value per share at
December 31, 1995 as adjusted to give effect to this offering.

    The following table illustrates the  dilution per share taking into  account
estimated expenses of this offering:

Dilution to investors in this offering.......................             $   15.33

</TABLE>

    The  foregoing calculations take into account the underwriting discounts and
other estimated  expenses  of  this  offering and  assume  no  exercise  of  the
Underwriters' over-allotment option. If the over-allotment

                                       10
<PAGE>
option  to  purchase up  to  an additional  375,000  shares of  Common  Stock is
exercised in full, the pro forma net tangible book value would be  approximately
$2.98 per share, resulting in a dilution to investors in this offering of $15.15
per share.

    The  dilution described above  could be substantially  greater, depending on
the conversion rates of  the series of the  Company's preferred stock issued  to
Ortho  and HMRI. See Notes 4 and 8 of Notes to Consolidated Financial Statements
elsewhere  herein  and  "Management's  Discussion  and  Analysis  of   Financial
Condition and Results of Operations -- Liquidity and Capital Resources."

    The following table sets forth the capitalization of the Company at December
31,  1995 and as  adjusted to give  effect to (i)  the sale of  the Common Stock
offered in this offering, (ii) the net  proceeds from the sale of $22.0  million
of  preferred  stock  to  HMRI described  elsewhere  herein,  (iii)  the Warrant
Repurchase, and  (iv)  in  each  case,  the  application  of  the  net  proceeds
therefrom. See "Use of Proceeds."

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
     (REFERENCES TO YEARS ARE TO THE COMPANY'S FISCAL YEARS ENDED JUNE 30.)

    Alliance  has  devoted  substantial resources  to  research  and development
related to its pharmaceutical products based upon PFC and emulsion technologies.
The Company has been unprofitable since inception and expects to incur operating
losses for at  least the next  several years due  to continued requirements  for
research  and development,  preclinical testing and  clinical trials, regulatory
activities, and commercial manufacturing start-up. The amount of net losses  and
the  time required by the Company  to achieve profitability are highly uncertain
due to differences in the timing  of revenues earned and expenses incurred.  The
Company  has entered into collaborative research and development agreements with
pharmaceutical companies  that generate  revenue  to augment  the level  of  its
research  and development activities and to  offset portions of its research and
development costs. See  "Business -- Collaborative  Agreements." The timing  and
amounts  of such revenue,  if any, cannot  be predicted with  certainty and will
likely fluctuate  sharply. To  date,  the Company's  revenue  from the  sale  of
products  has been immaterial. The majority of the Company's products are in the
development stage and there can be no assurance as to whether or when it will be
able to increase its revenues significantly. There can be no assurance that  the
Company will be able to achieve profitability at all or on a sustained basis.

RESULTS OF OPERATIONS

SIX MONTHS ENDED DECEMBER 31, 1995 AS COMPARED WITH SIX MONTHS ENDED DECEMBER
31, 1994

    The  Company's license  and research  revenue was  $4.1 million  for the six
months ended December  31, 1995,  compared to $7.1  million for  the six  months
ended  December 31, 1994. The period ended December 31, 1994 included a one-time
license fee of $4.0 million.

    Research and development expenses decreased by 19% to $15.6 million for  the
six months ended December 31, 1995, compared to $19.1 million for the six months
ended  December 31, 1994. The decrease in expenses was primarily the result of a
$3.6 million reduction in purchases of  raw materials, a $929,000 net  reduction
in  acquired research and development expense, and reduced staffing costs. These
reductions were partially offset by $639,000 paid to a supplier under a previous
raw material commitment. The Company also increased payments to universities and
outside consultants. The  expenses for the  six months ended  December 31,  1994
included  a one-time  $1.7 million  charge to  research and  development expense
which arose when the Company licensed product rights to Ortho. The expenses  for
the  six months ended December 31, 1995  included a $757,000 charge arising from
the acquisition of certain PFC patents, patent rights, and related documents  in
exchange  for 50,000 shares of Common Stock  and a five-year warrant to purchase
up to an additional 100,000 shares of Common Stock at $10.00 per share.

    General and administrative expenses decreased by 11% to $3.4 million for the
six months ended December 31, 1995, compared to $3.8 million for the six  months
ended December 31, 1994. The decrease in general and administrative expenses was
primarily due to decreased professional fees.

    Investment  income and other was $430,000  for the six months ended December
31, 1995, compared to $575,000 for the  six months ended December 31, 1994.  The
decline was primarily a result of lower average cash balances.

1995 AS COMPARED WITH 1994

    The  Company's license  and research revenue  increased to  $11.6 million in
1995 compared  to $163,000  in 1994.  The  increase was  primarily due  to  $4.0
million of license revenue and $7.1 million of research revenue derived from the
Ortho License Agreement.

    The  Company incurred  total operating expenses  of $42.1  million for 1995.
Operating expenses  include  $5.0 million  for  purchases of  raw  material  for
certain  products  currently being  developed,  $1.8 million  for  OXYGENT costs
incurred prior  to  execution  of  the Ortho  License  Agreement,  $545,000  for
products  no  longer  promoted or  developed  by  Alliance, and  a  $1.7 million
non-cash charge related to the license of previously capitalized product rights.
The $5.0 million charge for the purchase of raw materials arises from a December

                                       14
<PAGE>
1993 agreement the Company entered into with a supplier. In 1996, charges  under
the  agreement will  be substantially  less than in  1995. In  January 1994, the
Company regained  from  Boehringer  Ingelheim  International  GmbH  ("BII")  all
marketing  and  manufacturing  rights to  certain  IMAGENT  products, diagnostic
imaging agents, and OXYGENT  products outside of  North America. In  conjunction
with  the acquisition  of the marketing  and manufacturing rights  from BII, the
Company recorded product rights of $1.8 million, based on the value of  warrants
issued  to acquire the  rights. The unamortized portion  ($1.7 million) of these
product rights was charged to research and development expense when the  Company
licensed these product rights to Ortho.

    Research and development expenses increased by 11% to $35.1 million for 1995
compared to $31.6 million for 1994. The growth in expenses is primarily a result
of  increased raw material  costs and the product  rights charge discussed above
and increased salary costs. These expenses were partially offset by a  reduction
in payments to universities and outside consultants.

    General and administrative expenses decreased by 3% to $7.1 million for 1995
compared  to  $7.3 million  for 1994.  During  the fourth  quarter of  1995, the
Company was successful in recovering $1.6 million from its insurance carrier  to
offset professional fees incurred in connection with the defense of its lawsuit.

    Investment  and  other income  was $1.2  million for  1995 compared  to $1.6
million for 1994. The  decline in investment revenue  was primarily a result  of
lower average cash balances.

1994 AS COMPARED WITH 1993

    The Company had net product revenue of $246,000 for 1994 compared to $50,000
for  1993. In August 1993,  the Company received FDA  approval to market IMAGENT
GI, a magnetic  resonance ("MR")  imaging contrast  agent. The  increase in  net
product revenue from 1993 to 1994 was primarily attributable to sales of IMAGENT
GI  and SAT PAD, an MR  imaging accessory. Sales of IMAGENT  GI and SAT PAD were
not expected to provide significant revenue  to the Company. In September  1994,
the  Company discontinued promotional  activities for IMAGENT  GI due to limited
revenue potential.

    License and research revenue decreased to $163,000 for 1994 compared to $2.3
million for 1993. The Company's 1993 license and research revenue was  primarily
derived from the BII agreements. In July 1993, the BII agreements were modified,
which resulted in BII discontinuing all contract payments.

    Research and development expenses increased by 28% to $31.6 million for 1994
compared to $24.8 million for 1993. The growth in expenses reflects increases in
staffing,  costs  of preclinical  testing  and clinical  trials,  and additional
laboratory supplies and equipment  associated with the  growth of the  Company's
research  and  development  efforts. Due  to  the discontinuance  of  IMAGENT GI
promotional activities, the  Company reduced its  perflubron inventories to  the
estimated  net realizable value from sales of  IMAGENT GI, resulting in a charge
of $2.1 million.

    General and administrative  expenses increased  by 14% to  $7.3 million  for
1994  compared to $6.4 million  for 1993. The increases  were principally due to
increases in staffing to support the growth of product research and  development
efforts,  and professional fees  incurred in connection with  the defense of the
lawsuit.

    Investment and  other income  was $1.6  million for  1994 compared  to  $2.4
million  for 1993. The decline  in investment revenue was  primarily a result of
lower average cash and short-term investment balances.

LIQUIDITY AND CAPITAL RESOURCES

    Through December 1995,  the Company financed  its activities primarily  from
public  and  private  sales  of  equity  and  funding  from  collaborations with
corporate partners. In February 1996, the Company entered into the HMRI  License
Agreement,   which  provides  HMRI  with   worldwide  marketing  rights  to  the
intratracheal administration  of  liquids, including  LIQUIVENT,  which  perform
bronchoalveolar  lavage  or liquid  ventilation. The  product will  be developed
jointly by Alliance and HMRI, with HMRI responsible for substantially all of the
costs of development and marketing after March 31, 1996. In conjunction with the
HMRI License Agreement, HMRI agreed to purchase shares of Series B and Series  C
Preferred  Stock for $22.0 million. In  addition, HMRI will pay Alliance license
fees, milestone payments, and royalties on

                                       15
<PAGE>
product sales. HMRI  will also receive  a five-year warrant  to acquire  300,000
shares  of Common Stock  at $20.00 per  share. Closing of  the transactions with
HMRI is subject to expiration or  early termination of the waiting period  under
the  HSR Act  and other customary  conditions, all  of which are  expected to be
satisfied within the next thirty days.  However, there can be no assurance  that
the transactions with HMRI will be consummated.

    In August 1995, the Company entered into a loan and security agreement under
which  the Company received  $2.2 million. Amounts  borrowed under the agreement
are secured by fixed assets, and will  be repaid over three years commencing  in
September  1995. If certain financial covenants  are not satisfied, the debt may
become due and payable. The Company has financed substantially all of its office
and research facilities and related leasehold improvements under operating lease
arrangements.

    In April 1995,  the Company  completed offerings  of 3.2  million shares  of
newly  issued  Common  Stock,  resulting  in  net  proceeds  to  the  Company of
approximately $14.3 million.

    In August 1994,  the Company entered  into the Ortho  License Agreement  for
injectable  PFC emulsions  capable of  transporting oxygen  for therapeutic use,
including OXYGENT. Under the Ortho License Agreement, Ortho paid to Alliance  an
initial fee of $4.0 million and will make other payments upon the achievement of
certain  milestones. Ortho  is responsible  for substantially  all the remaining
costs of developing and marketing the  products and will pay Alliance a  royalty
based  upon sales of products after  commercialization. From August 1994 through
December 31, 1995, the  Company had received research  revenue payments of  $9.1
million  from Ortho, and as  of December 31, 1995,  had recorded a receivable of
$2.0 million, which  was received  subsequently. In conjunction  with the  Ortho
License  Agreement, J&JDC  purchased 1.5  million shares  of Series  A Preferred
Stock for $15.0 million  and obtained a three-year  warrant to purchase  300,000
shares of Common Stock at $15.00 per share.

    The  Company had net working  capital of $11.1 million  at December 31, 1995
compared  to  $22.3  million  at  June  30,  1995.  The  Company's  cash,   cash
equivalents,  and short-term investments decreased  to $12.7 million at December
31, 1995 from $23.5  million at June 30,  1995. The decrease resulted  primarily
from  net cash  used in  operations of $12.1  million, and  property, plant, and
equipment additions of $1.4 million related to the expansion of facilities  used
for  research,  development,  and  pilot  manufacturing.  These  decreases  were
partially offset  by  $2.2 million  received  under  the August  1995  loan  and
security agreement, and $675,000 from the issuance of Common Stock upon exercise
of  options. Capital expenditures for 1996  are expected to increase compared to
1995. The  Company's operations  to date  have consumed  substantial amounts  of
cash, and are expected to continue to do so for the foreseeable future.

    In  December 1993, in order to obtain a commitment for a long-term supply of
raw  material  for  both  clinical  trials  and  anticipated  future  production
requirements,  the Company entered into an agreement with a supplier under which
the Company was  obligated to  make payments to  the supplier  through May  1997
based,  in  part, upon  the achievement  of certain  milestones. Based  upon the
supplier's intent to negotiate directly  with the Company's existing and  future
collaborative  partners, that agreement  was modified in  July 1995 to terminate
certain commitments  by both  parties.  Some or  all  of the  Company's  payment
obligations  that remain may be reimbursed to the Company by existing and future
collaborative partners.

    The Company continually  reviews its  product development  activities in  an
effort  to allocate its  resources to those product  candidates that the Company
believes have  the  greatest commercial  potential.  Factors considered  by  the
Company  in determining  the products  to pursue  include projected  markets and
need, potential for  regulatory approval  and reimbursement  under the  existing
healthcare  system,  status of  its  proprietary rights,  technical feasibility,
expected and known product attributes, and estimated costs to bring the  product
to  market. Based on these and other factors,  the Company may from time to time
reallocate its resources among its product development activities. Additions  to
products   under  development   or  changes   in  products   being  pursued  can
substantially and rapidly change the Company's funding requirements.

    The Company expects to incur substantial additional expenditures  associated
with  product  development.  The  Company  will  seek  additional  collaborative
research and development relationships with suitable corporate partners for  its
non-licensed  products. There  can be no  assurance that  such relationships, if
any,

                                       16
<PAGE>
will successfully reduce the  Company's funding requirements. Additional  equity
or debt financing may be required, and there can be no assurance that funds from
these  sources will  be available  on reasonable terms,  if at  all. If adequate
funds are not available, the  Company may be required  to delay, scale back,  or
eliminate  one  or more  of its  product development  programs, or  obtain funds
through arrangements with collaborative partners or others that may require  the
Company to relinquish rights to certain of its technologies, product candidates,
or products that the Company would not otherwise relinquish.

    Alliance anticipates that its existing capital resources, including expected
revenues  from  the  License Agreements  and  investments,  as well  as  the net
proceeds from  this offering  and income  earned thereon,  will be  adequate  to
satisfy  its capital requirements for at least the next 24 months. The Company's
future capital requirements  will depend  on many  factors, including  continued
scientific  progress  in its  research and  development programs,  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 ability of
the Company to establish additional collaborative relationships, and the cost of
manufacturing scale-up.

    During September 1992, the Company and certain of its officers and directors
were named as defendants  in several lawsuits filed  in the U.S. District  Court
for  the Southern  District of California  by certain  shareholders. The actions
were  consolidated  into  one  class  action  lawsuit  titled  "In  re  Alliance
Pharmaceutical  Securities  Litigation."  The  complaint  claimed,  among  other
things, that the defendants failed to disclose certain problems with two of  the
Company's products under development, which conduct is alleged to have portrayed
falsely the Company's financial condition. On May 25, 1995, summary judgment was
granted  in favor of the  Company and its officers  and directors. Attorneys for
the plaintiffs have appealed the decision. A  hearing on the appeal has not  yet
been scheduled. The Company believes the eventual outcome of the litigation will
not have a material adverse effect on the Company's financial condition.

    The  Company's business is subject to significant risks that could cause the
Company's  results   to  differ   materially  from   those  expressed   in   any
forward-looking  statements  made in  this Prospectus.  These risks  include the
matters set forth above under this caption, under "Risk Factors," and  elsewhere
herein.

OVERVIEW

    Alliance  is a pharmaceutical research  and development company that focuses
on developing scientific discoveries into potential drug products and  licensing
these  products to multinational pharmaceutical  companies in exchange for fixed
payments and royalties. To  date, the Company has  entered into agreements  with
researchers  for the rights to two innovative products, developed these products
through  initial  clinical  (human)  trials,  and  entered  into   collaborative
relationships  with multinational pharmaceutical companies  for the final stages
of  development  and  worldwide  marketing.  These  products  are  OXYGENT,   an
intravascular  oxygen  carrier  designed  to reduce  the  need  for  donor blood
transfusions during surgery, which is currently in Phase IIb clinical trials and
is licensed to affiliates of Johnson & Johnson, and LIQUIVENT, an intrapulmonary
agent for use in treatment of acute respiratory failure, which is currently in a
pivotal Phase II/III clinical trial and  is licensed to Hoechst Marion  Roussel,
Inc., an affiliate of Hoechst AG. Alliance intends to enter into a collaborative
agreement  for IMAGENT  US, an ultrasound  contrast agent for  which the Company
expects to begin clinical trials in the near future.

    The Company's strategy is to identify potential new pharmaceutical  products
through   scientific   collaborations   with  researchers   and   clinicians  in
universities and medical centers where many  of the basic causes of disease  and
potential  targets for  new therapies  are discovered.  Using its  experience in
defining  pharmaceutical   formulations,  designing   manufacturing   processes,
conducting  preclinical  pharmacology  and  toxicology  studies,  and conducting
early-phase human testing, Alliance endeavors  to advance such discoveries  into
clinical  development.  The Company  seeks  collaborative relationships  for the
final stages of drug development, including completing late-phase human testing,
obtaining worldwide  regulatory  approvals, building  large-scale  manufacturing
capacities, and marketing.

    The Company's headquarters are located at 3040 Science Park Road, San Diego,
California 92121, and its telephone number is (619) 558-4300.

PRODUCTS IN CLINICAL DEVELOPMENT

    Alliance's products currently in clinical development -- OXYGENT, LIQUIVENT,
and  IMAGENT  US --  are  based upon  PFC  and emulsion  technologies.  PFCs are
biochemically inert compounds and  may be employed in  a variety of  therapeutic
and diagnostic applications. The Company's primary drug substance is perflubron,
a  brominated PFC that  has a high  solubility for respiratory  gases and can be
used to transport these gases safely throughout the body.

    OXYGENT.  OXYGENT,  an emulsion containing  perflubron, is an  intravascular
oxygen carrier to be used as a temporary "blood substitute" to provide oxygen to
tissues  during elective surgeries where  substantial blood loss is anticipated.
It is estimated that in excess of three million patients annually in the  United
States  may  receive  one or  more  units  of blood  during  elective surgeries,
including,  for  example,  cardiovascular,  orthopedic,  and  general   surgical
procedures.  An oxygen carrier could  be used instead of  blood for a portion of
these patients.  The  OXYGENT dose  for  surgical applications  is  expected  to
provide the equivalent oxygen delivery of at least two units of red blood cells.

    OXYGENT  has several potential advantages over the use of allogeneic (donor)
blood: there is  no risk of  infectious disease transmission;  it is  compatible
with  all blood types; it has a shelf-life in  excess of one year; and it can be
sterilized. According  to  the 1994  estimates  of The  National  Institutes  of
Health,  the risks per unit of blood transfused in the United States are 1:2,500
for bacterial infections, 1:3,000 for  hepatitis, 1:100,000 for fatal  hemolytic
reactions,  primarily due  to clerical  error, and  1:225,000 for  HIV infection
(AIDS). To  minimize the  use of  allogeneic  blood and  to avoid  these  risks,
certain  techniques  can  be  employed  that  allow  use  of  the  patient's own
(autologous) blood during surgery. These techniques include (i) predonation,  in
which  patients donate several units  of their blood in  the six weeks preceding
surgery,  (ii)  perioperative  hemodilution,  in  which  several  units  of  the
patient's blood are removed just prior to surgery and are replaced with a plasma
expander,  and (iii) salvage, wherein  a device (cell saver)  is used to collect
blood lost during the surgical procedure. OXYGENT can be used with any of  these
autologous  blood collection techniques to enhance  safety, by reducing the need
for allogeneic blood. When a blood transfusion

                                       18
<PAGE>
is indicated during surgery, one or more doses of OXYGENT would be used in place
of allogeneic blood to maintain an  adequate level of oxygen delivery despite  a
lower  red blood cell concentration.  This use of OXYGENT  delays or reduces the
need for the transfusion of donor blood, thereby avoiding its associated risks.

    In October 1995,  the Company and  Ortho commenced a  Phase IIb  randomized,
controlled,  efficacy trial involving surgical patients at multiple sites in the
United States. A  similar Phase IIb  clinical study was  commenced in Europe  in
January 1996. In February 1996, the Company and Ortho commenced a Phase II study
in the United States in cardiopulmonary bypass patients.

    In  August 1994, the Company entered into the Ortho License Agreement, which
provides Ortho with worldwide marketing  rights to the Company's injectable  PFC
emulsions capable of transporting oxygen for therapeutic use, including OXYGENT.
The  product is being developed jointly by  Alliance and Ortho, with Ortho being
responsible for  substantially all  of the  remaining costs  of development  and
marketing.

    LIQUIVENT.   LIQUIVENT, sterile  perflubron, is an  intrapulmonary agent for
treatment of acute  respiratory failure, a  disorder that can  result from  many
causes,   including  serious  infections,  traumatic  shock,  severe  burns,  or
inhalation  of  toxic  substances.   Acute  respiratory  failure  is   generally
characterized  by an excessive inflammatory response, which leads to blockage of
the small airways and collapse of alveoli, resulting in inadequate gas  exchange
and  impairment  of  normal  lung  function.  Each  year,  approximately 235,000
patients in the United  States are placed on  mechanical gas ventilators for  at
least  four days for  treatment of lung  dysfunction due to  acute injuries. The
most urgent  need for  these patients  is to  improve their  blood  oxygenation.
However,  the prolonged  use of  high ventilatory  pressures or  high continuous
concentrations of inspired oxygen can damage the patient's lungs. Some of  these
patients may benefit from treatment with LIQUIVENT.

    LIQUIVENT  is  intended to  be  used in  a  technique called  partial liquid
ventilation ("PLV").  In this  procedure, the  drug is  administered through  an
endotracheal  tube into the lungs  of a patient being  supported by a mechanical
ventilator. The  initial goal  of  LIQUIVENT/PLV therapy  is to  open  collapsed
alveoli  to improve  gas exchange. Once  this has  been accomplished, ventilator
pressure and oxygen concentration may be lowered to minimize  ventilator-induced
lung  trauma. In clinical  studies, LIQUIVENT has also  been observed to promote
the migration  of  mucus and  alveolar  debris  to the  central  airways,  where
suctioning is easier. The ability to remove such debris may significantly reduce
the  excessive inflammatory  response associated with  acute respiratory failure
and enhance the  effectiveness of other  therapeutic interventions, all  serving
potentially  to  reduce patient  recovery time.  Published results  from initial
clinical trials have indicated that LIQUIVENT improved lung oxygenation, without
clinically significant side effects.  In addition, preclinical studies  indicate
LIQUIVENT  may  mitigate  inflammation,  ventilator-induced  trauma,  and oxygen
toxicity.

    In January  1996, the  Company  began a  multi-center pivotal  Phase  II/III
clinical  trial  with LIQUIVENT  in  pediatric patients  with  acute respiratory
failure, and  separate  multi-center Phase  II  clinical trials  in  adults  and
premature  infants are underway. The FDA has granted Subpart E status (expedited
review) for the product.

    In February 1996, the Company entered into the HMRI License Agreement, which
provides  HMRI  with  worldwide  marketing  and  manufacturing  rights  to   the
intratracheal  administration  of  liquids, including  LIQUIVENT,  which perform
bronchoalveolar lavage  or liquid  ventilation. The  product will  be  developed
jointly by Alliance and HMRI, with HMRI responsible for substantially all of the
costs  of  development  and  marketing  after March  31,  1996.  Closing  of the
transactions with HMRI  is subject  to expiration  or early  termination of  the
waiting  period under the HSR  Act and other customary  conditions, all of which
are expected to be satisfied within the next thirty days. However, there can  be
no assurance that the transactions with HMRI will be consummated.

    IMAGENT  US.  IMAGENT US is an  ultrasound contrast agent being developed to
aid in the assessment of cardiac  function and myocardial perfusion, as well  as
the  detection of solid organ lesions and blood flow abnormalities. More than 30
million scans  of the  heart, vasculature,  and abdominal  organs are  performed
annually  in the  United States,  some of which  may potentially  benefit from a
cost-effective contrast agent. To be  successful in the marketplace,  ultrasound
contrast agents should provide enhanced diagnostic images during several minutes
of  scanning, be easy to  use, be stable during  transportation, and have a long
shelf-life. IMAGENT US is being developed to meet these requirements.

                                       19
<PAGE>
    IMAGENT US is a powder comprising hollow microspheres containing a PFC-based
gaseous mixture and water-soluble components that are known to be acceptable for
parenteral use. Prior to use, IMAGENT US is reconstituted with sterile water  to
form  microbubbles that are then injected into  the patient. The gas bubbles are
highly echogenic and, when delivered intravenously, reflect signals that enhance
ultrasonic images. In preclinical studies, IMAGENT US has been found to  enhance
the  ultrasound signal from perfused tissues and blood vessels using traditional
gray-scale and  color Doppler  technologies, as  well as  the emerging  harmonic
ultrasound  imaging technique. In  February 1996, the Company  filed an IND with
the FDA and clinical trials are expected to begin in the near future.

OTHER PRODUCTS

    Alliance is supporting internal research efforts to expand the applicability
of its core technologies. The Company has patented fluorinated surfactants  that
are potentially useful in the preparation of therapeutic or diagnostic emulsions
and other formulations. Certain of these surfactants have been licensed to Glaxo
Group  Limited ("Glaxo") to be  used as a component  of its metered dose inhaler
delivery system for respiratory drugs.

    Alliance is  investigating  the  use of  PFC-containing  reverse  emulsions,
microemulsions,  gels, foams,  and other  compositions as  drug delivery agents.
These compositions are either aqueous or oil-based, and may be administered  via
oral,  intravenous, intrapulmonary, or topical routes to distribute antibiotics,
chemotherapy agents, gene  therapies, or  other medicaments  systemically or  to
selected areas of the body. Alliance is also conducting preclinical studies of a
PFC  emulsion  that could  be beneficial  for  warm temperature  preservation of
kidneys or  other organs  which may  extend the  time the  organ is  viable  for
transplantation.

    The  Company  has  initiated a  pilot  clinical  study in  Europe  to assess
OXYFLOW, an apparatus designed to  be a combined cardiovascular and  oxygenation
monitor  that acquires data by minimally invasive means. This device is intended
to  provide  on-line   information  pertaining  to   oxygen  status  and   other
physiological  parameters,  which  could assist  physicians  in  their decisions
regarding transfusions and other interventions.

    The Company has  certain agreements  with research  institutions to  develop
discoveries  that  the  Company  believes  may be  the  basis  of  new products.
Antigenized  antibodies  that  could  potentially  stimulate  or   down-regulate
antibody  production are being  developed in conjunction  with Mt. Sinai Medical
Center in  New York  City. A  prototype  vaccine for  infectious disease  and  a
prototype  tolerogen for an  autoimmune disease are  also under development with
Mt.  Sinai.  In  addition,  Alliance  is  working  with  researchers  at  Temple
University  to develop an  apoptotic factor for regulating  the death of certain
cancer cells.

    The Company has developed and is  marketing SAT PAD, a re-usable MR  imaging
accessory  that improves  the quality of  images obtained by  certain MR imaging
techniques.  SAT  PAD  is  distributed  by  dealers  specializing  in  radiology
products.  Sales of  SAT PAD  were approximately  $176,000 for  fiscal 1995. The
Company expects that the sales  volume of SAT PAD will  be limited and does  not
anticipate significant revenue from the product.

    The Company intends to consider other technologies that may be available for
licensing and research agreements with other institutions or inventors. Alliance
intends,  where appropriate, to seek outside  sources of funding. If new license
and research agreements are added and the Company is not able to obtain  outside
sources of funding, the Company's research and development expenses are expected
to increase significantly.

    There  can be no assurance  that any of these  products will be successfully
commercialized.

COLLABORATIVE RELATIONSHIPS

    HOECHST MARION ROUSSEL, INC.  In February 1996, the Company entered into the
HMRI License Agreement, which provides  HMRI with worldwide marketing rights  to
the  intratracheal administration of liquids, including LIQUIVENT, which perform
bronchoalveolar lavage  or liquid  ventilation. The  product will  be  developed
jointly by Alliance and HMRI, with HMRI responsible for substantially all of the
cost  of development and marketing after March 31, 1996. In conjunction with the
HMRI License Agreement, HMRI agreed to purchase 750,000 shares of the  Company's
Series  B Preferred Stock and 200,000 shares of its Series C Preferred Stock for
an aggregate of $22.0 million. In addition, HMRI will pay Alliance license fees,

                                       20
<PAGE>
milestones payments, and royalties  on product sales. HMRI  will also receive  a
five-year warrant to acquire 300,000 shares of Common Stock at $20.00 per share.
The Series B Preferred Stock is convertible into shares of Common Stock upon the
earliest  of: (i)  the Common  Stock closing at  a price  per share  of at least
$20.00 for  twenty  consecutive  days;  (ii) termination  of  the  HMRI  License
Agreement;  or (iii) February 28,  2001. Each share of  Series B Preferred Stock
will be converted into a number of  shares of Common Stock based upon the  lower
of  the average closing price  of the Common Stock  over the twenty trading days
preceding the time  of conversion or  $20.00 per share.  The Series C  Preferred
Stock  converts automatically on June 30, 1997 into a number of shares of Common
Stock obtained by dividing  the average closing price  of the Common Stock  over
the  twenty trading days preceding January 14,  1997 into $5.0 million. Prior to
June 29, 1997, HMRI may, if the HMRI License Agreement is terminated, redeem the
Series C Preferred Stock for $15.0 million,  payable in cash or Common Stock  at
Alliance's  election,  any  time  on  or before  the  expiration  of  five years
following the  redemption date.  Prior to  conversion, each  share of  Series  B
Preferred  Stock is entitled  to one vote  on matters on  which shareholders are
entitled to  vote. The  Series B  Preferred Stock  carries a  cumulative  annual
dividend of $1.00 per share. The Series C Preferred Stock does not have dividend
or voting rights. Closing of the transactions with HMRI is subject to expiration
or early termination of the waiting period under the HSR Act and other customary
conditions,  all of which  are expected to  be satisfied within  the next thirty
days. However, there can be no assurance that the transactions with HMRI will be
consummated.

    ORTHO BIOTECH, INC.   In  August 1994, the  Company entered  into the  Ortho
License  Agreement for injectable  PFC emulsions capable  of transporting oxygen
for therapeutic use, including OXYGENT. Under the Ortho License Agreement, Ortho
paid to Alliance an  initial fee of  $4.0 million and  will make other  payments
upon   the  achievement  of   certain  milestones.  Ortho   is  responsible  for
substantially all the remaining costs  of developing and marketing the  products
and   will  pay  Alliance   a  royalty  based  upon   sales  of  products  after
commercialization. In  conjunction  with  the  Ortho  License  Agreement,  J&JDC
purchased  1.5 million shares of Series A  Preferred Stock for $15.0 million. On
or before June  30, 1998, each  share of the  Series A Preferred  Stock will  be
converted  into shares of Common Stock based upon the lower of the average price
of Common  Stock  at the  time  of conversion  or  $20.00 per  share.  Prior  to
conversion,  each share of Series A Preferred Stock is entitled to one-half vote
on matters on which  shareholders are entitled to  vote. The Series A  Preferred
Stock  carries a cumulative annual cash dividend  of $0.50 per share. Ortho also
obtained a three-year  warrant to  purchase 300,000  shares of  Common Stock  at
$15.00 per share.

    The  Company intends to enter into  a collaborative relationship for IMAGENT
US, an ultrasound contrast agent for which the Company expects to begin clinical
trials in the near future.

    The Company  entered into  a license  agreement with  Glaxo for  the use  of
certain  of the Company's fluorinated surfactants  in metered dose inhalers that
deliver Glaxo's  respiratory drug  formulations. Glaxo  is responsible  for  the
development  and marketing  of metered  dose inhaler  products incorporating the
Company's surfactants. The  agreement provides  for an initial  license fee  and
milestone payments to Alliance, which are not expected to exceed $2.5 million in
the aggregate, with royalties, if any, to Alliance following commercialization.

    There  can be  no assurances  that the  Company will  be able  to enter into
future collaborative relationships on acceptable  terms. The termination of  any
collaborative relationship or failure to enter into such relationships may limit
the  ability of the  Company to develop  its technology and  may have a material
adverse effect on the Company's business.

MARKETING

    Under the  terms  of  the  Ortho  License  Agreement,  Ortho  has  exclusive
worldwide  marketing rights  to OXYGENT  and any  other injectable  PFC emulsion
products capable of transporting oxygen  for therapeutic use. Upon  consummation
of the HMRI transactions, HMRI will have exclusive worldwide marketing rights to
the  intratracheal administration of liquids, including LIQUIVENT, which perform
bronchoalveolar lavage or liquid ventilation.  The Company has not yet  selected
its marketing partner for IMAGENT US. The Company's only commercialized product,
SAT  PAD, is  currently distributed through  certain distributors  of MR imaging
equipment and imaging products.

                                       21
<PAGE>
MANUFACTURING

    The Company manufactures  all of  its products for  preclinical testing  and
clinical  trials. OXYGENT  is produced in  Alliance's San  Diego facility, which
includes both a pilot plant  and a production-scale manufacturing facility.  The
Company  believes that this production facility will provide sufficient capacity
for future clinical trials and market launch of OXYGENT, if and when approved by
the FDA. However,  a larger commercial-scale  facility will be  required in  the
future.  Under the terms of the Ortho  License Agreement, Ortho has the right to
elect to manufacture OXYGENT itself or have the Company continue to do so, which
election must  be  made at  or  prior  to the  filing  of an  NDA.  If  Alliance
manufactures  OXYGENT for Ortho, the transfer price, which will not be less than
Alliance's fully burdened cost,  will be determined by  Ortho's net sales  price
for  the  product.  The Company  has  not  selected a  commercial-scale  site or
obtained any regulatory approvals. Construction  of such a facility will  depend
upon  Ortho's  decision  regarding manufacturing,  product  development, capital
resources, and regulatory approvals, among other things.

    LIQUIVENT is manufactured  for clinical trials  at the Company's  Otisville,
New York facility. LIQUIVENT is the same drug substance as IMAGENT GI, for which
Alliance  obtained FDA approval in August 1993  as an oral contrast agent for MR
imaging. As a result, certain chemistry, manufacturing, and control requirements
have been accepted by the FDA, which  may benefit the Company in the  regulatory
review  process. The HMRI License Agreement  requires the Company to manufacture
LIQUIVENT at its Otisville facility for a period of time after market launch  at
a  negotiated  price.  HMRI  will  be  responsible  for  establishing production
capacity beyond the maximum capacity of the Otisville facility.

    IMAGENT US is manufactured for clinical  studies at the San Diego  facility,
using  a proprietary process to form dry, PFC vapor-containing spheres which are
reconstituted with sterile  water to form  microbubbles just prior  to use.  The
facility  is expected  to provide  sufficient capacity  for clinical  trials and
market launch.

SOURCES AND AVAILABILITY OF RAW MATERIALS

    The Company has obtained perflubron, the principal raw material utilized  in
OXYGENT  and LIQUIVENT, from several large chemical suppliers, and believes that
it has sufficient inventory of the drug substance for clinical trials. HMRI  and
Ortho  have indicated an intent to secure  a long-term supply of perflubron from
manufacturers. The Company believes it has a sufficient supply of raw  materials
for  IMAGENT US for clinical trials.  The Company's business could be materially
and adversely affected if it or its collaborative partners were unable to obtain
necessary raw materials on a timely basis and at a cost-effective price.

PATENTS

    The Company  seeks  proprietary  protection  for  its  products,  processes,
technologies,   and  ongoing  improvements.  The   Company  is  pursuing  patent
protection in the  United States  and in foreign  countries that  it regards  as
important  for future endeavors. Numerous patent applications have been filed in
the European Patent Office, Australia,  Canada, Ireland, Israel, Japan,  Norway,
and South Africa, and patents have been granted in some of these countries.

    The  Company  has  seven issued  U.S.  patents  related to  or  covering PFC
emulsions. Such emulsions are the basis  of the Company's OXYGENT products.  The
issued  patents and other pending patent  applications cover specific details of
emulsified PFCs, and include product-by-process claims, method claims describing
their manufacture and use, and some composition claims. These broadly cover high
concentration PFC emulsions, typically 40-125% weight per volume (although  some
are limited to 75-125% weight per volume), and manufacturing methods.

    In  September 1994, Alliance received a U.S. patent for its preferred method
of using blood substitutes to facilitate oxygen delivery. A related U.S.  patent
was  issued  in September  1995. Corresponding  patents  are pending  in Europe,
Japan, and other  countries. The  issued claims cover  methods for  facilitating
autologous  blood use in conjunction  with administering oxygen-enriched gas and
oxygen carriers  that contain  fluorochemicals, as  well as  those derived  from
human, animal, plant, or recombinant hemoglobin, in order to reduce or eliminate
the need for allogeneic blood transfusions during surgery.

    The  Company has filed U.S. and foreign patent applications on its method of
using  oxygen-carrying  PFCs  to  enhance  respiratory  gas  exchange  utilizing
conventional  gas ventilators.  In August  1995, a  U.S. patent  licensed to the
Company issued. The patent covers  a method of administering liquids,  including

                                       22
<PAGE>
LIQUIVENT,   to  patients.  Another  U.S.  patent,  covering  other  methods  of
administration of  liquids,  including LIQUIVENT,  to  patients, was  issued  in
February  1996. The Company has patent  applications pending which seek to cover
the use of PFCs to deliver drugs to the lungs and to wash debris from, and open,
collapsed lungs. In November 1995, the  Company received a U.S. patent  covering
the  use of  fluorochemicals to treat  localized and  systemic inflammation. The
Company also  has patent  applications pending  that cover  apparati for  liquid
ventilation using PFCs.

    The  Company has filed eight U.S.  patent applications related to IMAGENT US
concerning the composition, manufacture, and use of novel stabilized microbubble
compositions, which include applications based on its discovery that PFC  gases,
in  combination with appropriate surfactants, can stabilize microbubbles for use
in ultrasonic imaging. International applications  directed to the same  subject
matter have also been filed.

    The  Company has patents that  have issued in the  United States and abroad,
and additional  pending patents,  covering  its novel  fluorinated  surfactants.
These compounds may be useful in oxygen-carrying or drug-transport compositions,
and in liposomal formulations that have therapeutic and diagnostic applications.
Additional  fluorinated  compounds  disclosed  in  pending  applications  may be
employed in cosmetics, protective  creams, and lubricating agents.  Compositions
that  can be structured as emulsions, microemulsions,  and gels may be useful as
contrast enhancement agents for radiography  and scintigraphy. The Company  also
has  pending applications relating to microstructures (tubules, helixes, fibers)
that may  have  uses  in  the  fields  of  medicine,  biomolecular  engineering,
microelectronics, and electro-optics.

    Aside  from the issued  patents and allowed  applications referred to above,
however, no assurance can be given that any of these applications will result in
issued U.S. or foreign patents. Although  patents are issued with a  presumption
of  validity and require  a challenge with  a high degree  of proof to establish
invalidity, no assurance can be given that any issued patents would survive such
a challenge and would be valid and enforceable.

    The Company also  attempts to protect  its proprietary products,  processes,
and  other information  by relying on  trade secret laws  and non-disclosure and
confidentiality agreements with  its employees, consultants,  and certain  other
persons  who  have  access to  such  products, processes,  and  information. The
agreements affirm that all inventions  conceived by employees are the  exclusive
property  of  the Company,  with the  exception of  inventions unrelated  to the
Company's  business  and  developed  entirely   on  the  employee's  own   time.
Nevertheless,  there  can  be no  assurance  that these  agreements  will afford
significant protection against or adequate compensation for misappropriation  or
unauthorized disclosure of the Company's trade secrets.

COMPETITION

    Biotechnology and pharmaceutical companies are highly competitive. There are
many  pharmaceutical  companies,  biotechnology  companies,  public  and private
universities, and  research  organizations  actively  engaged  in  research  and
development  of products that may be similar to Alliance's products. Many of the
Company's  existing  or   potential  competitors   have  substantially   greater
financial,  technical, and  human resources than  the Company and  may be better
equipped to  develop,  manufacture, and  market  products. These  companies  may
develop  and introduce  products and processes  competitive with  or superior to
those of  the  Company. In  addition,  other  technologies or  products  may  be
developed that have an entirely different approach or means of accomplishing the
intended  purposes of the  Company's products, which  might render the Company's
technology and products  uncompetitive or  obsolete. There can  be no  assurance
that the Company will be able to compete successfully.

    Well-publicized  side effects associated with the transfusion of human donor
blood have spurred efforts to develop a blood substitute. Two primary approaches
have shown promise as  temporary oxygen carriers:  PFC emulsions and  hemoglobin
solutions.   Hemoglobin   development  efforts   include   chemically  modified,
stroma-free hemoglobin from  human or  bovine red blood  cells, and  the use  of
genetic  engineering  to  produce  recombinant  hemoglobin.  There  are  several
companies working on hemoglobin solutions as a blood substitute, three of  which
have  entered Phase II clinical trials. One major U.S. pharmaceutical company is
collaborating with  a company  developing a  recombinant hemoglobin-based  blood
substitute.  Alliance  is  aware  of two  other  companies  developing PFC-based
temporary oxygen carriers, one of which has entered Phase I clinical trials. The
Company believes that the relatively low cost and ease of production of  OXYGENT
provide advantages over hemoglobin-based products.

                                       23
<PAGE>
    Although  liquid ventilation therapy has been  in the research phase for the
last two decades, the  Company is unaware of  any potential competitor that  has
reached  the clinical  trial stage. However,  other companies  may be evaluating
compounds with the possibility of entering this field. If major manufacturers of
PFCs entered the field, the Company  could face competition from companies  with
substantially  greater resources. The Company  believes that its patent position
and stage of research and development give it an advantage over these  potential
competitors. Alliance is aware of other companies that are attempting to develop
alternative types of therapies for treatment of acute respiratory failure.

    Competition  in  the development  of ultrasound  imaging contrast  agents is
intense and is expected  to increase. There is  currently only one  commercially
available ultrasound imaging contrast agent for certain cardiology applications.
The  Company believes that other companies  are in advanced clinical trials with
ultrasound  contrast  agents.  The  Company  expects  that  competition  in  the
ultrasound contrast imaging agent field will be based primarily on the product's
safety profile, efficacy, stability, ease of administration, breadth of approved
indications,  and physician, healthcare payor,  and patient acceptance. Although
the Company believes that if and when IMAGENT US is approved for commercial sale
it will be well  positioned to compete successfully,  there can be no  assurance
that the Company will be able to do so.

PRODUCT LIABILITY CLAIMS AND UNINSURED RISKS

    The  sale or use of the Company's present products and any other products or
processes that may be developed or sold by the Company may expose the Company to
potential  liability  from  claims   by  end-users  of   such  products  or   by
manufacturers or others selling such products, either directly or as a component
of  other products. While the Company has product liability insurance, there can
be no assurance  that the Company  will continue to  maintain such insurance  or
that  it will provide adequate coverage. If  the Company is held responsible for
damages in a product liability suit, the Company's financial condition could  be
materially and adversely affected.

GOVERNMENT REGULATION

    The  Company's products require governmental  approval before production and
marketing can commence. The regulatory  approval process is administered by  the
FDA  in the  United States  and by  similar agencies  in foreign  countries. The
process of  obtaining regulatory  clearances  or approvals  is costly  and  time
consuming.  The  Company cannot  predict how  long  the necessary  clearances or
approvals will take or whether it will be successful in obtaining them.

    Generally, all potential pharmaceutical products must successfully  complete
two  major stages  of development  (preclinical and  clinical testing)  prior to
receiving marketing approval by the governing regulatory agency. In  preclinical
testing,  potential compounds are  tested both IN  VITRO and in  animals to gain
safety information  prior to  administration in  humans. Knowledge  is  obtained
regarding  the  effects of  the  compound on  bodily  functions as  well  as its
absorption, distribution, metabolism, and elimination.

    Clinical trials are typically conducted in three sequential phases, although
the phases may  overlap. In Phase  I, which frequently  begins with the  initial
introduction  of the drug into healthy human subjects prior to introduction into
patients, the compound will be tested for safety and dosage tolerance. Phase  II
typically  involves studies in a somewhat  larger patient population to identify
possible adverse  effects  and  safety risks,  to  begin  gathering  preliminary
efficacy  data, and to investigate potential dose sizes and schedules. Phase III
trials are undertaken to further evaluate clinical efficacy and to further  test
for  safety within  an expanded patient  population. Each trial  is conducted in
accordance with certain standards under protocols that detail the objectives  of
the  study,  the parameters  to  be used  to  monitor safety,  and  the efficacy
criteria to be evaluated. Each protocol must be submitted to the FDA as part  of
the IND. Further, each clinical study must be evaluated by an independent review
board  at the institution at which the study will be conducted. The review board
will consider,  among  other  things,  ethical  factors,  the  safety  of  human
subjects, and the possible liability of the institution.

    Following  completion  of  these studies,  a  new drug  application  must be
submitted to and  approved by  the FDA  in order to  market the  product in  the
United States. Similar applications are required in foreign

                                       24
<PAGE>
countries.  There can  be no  assurance that,  upon completion  of the foregoing
trials, the results will be considered adequate for government approval. If  and
when  approval is obtained to market a product, the FDA's (or applicable foreign
agency's) regulations will govern manufacturing and marketing activities.

    The FDA  has established  a designation  to speed  the availability  of  new
therapies   for  life-threatening   or  severely   debilitating  diseases.  This
designation, defined  in  Subpart  E  of  the  FDA's  investigational  new  drug
regulations,  may expedite clinical evaluation and regulatory review of some new
drugs, such as LIQUIVENT, which has been so designated.

    Perflubron is  an  eight-carbon  halogenated  fluorocarbon  liquid.  Certain
halogenated  fluorocarbons (primarily the gaseous chlorofluorocarbons) have been
implicated in stratospheric  ozone depletion.  The FDA  issued a  Finding of  No
Significant Impact under the National Environmental Protection Act in connection
with  the approval  for marketing IMAGENT  GI. See  "Business -- Manufacturing."
However, all materials  contained in  the Company's products  remain subject  to
regulation by governmental agencies.

    In  addition  to FDA  regulation, the  Company is  subject to  regulation by
various  governmental   agencies  including,   without  limitation,   the   Drug
Enforcement   Administration,   the   U.S.   Department   of   Agriculture,  the
Environmental  Protection   Agency,   the   Occupational   Safety   and   Health
Administration, and the California State Department of Health Services, Food and
Drug  Branch. Such regulation, by governmental  authorities in the United States
and other countries, may  impede or limit the  Company's ability to develop  and
market its products.

LEGAL PROCEEDINGS

    During September 1992, the Company and certain of its officers and directors
were  named as defendants in  several lawsuits filed in  the U.S. District Court
for the Southern  District of  California by certain  shareholders. The  actions
were  consolidated  into  one  class  action  lawsuit  titled  "In  re  Alliance
Pharmaceutical  Securities  Litigation."  The  complaint  claimed,  among  other
things,  that the defendants failed to disclose certain problems with two of the
Company's products under development, which conduct is alleged to have portrayed
falsely the Company's financial condition. On May 25, 1995, summary judgment was
granted in favor of  the Company and its  officers and directors. Attorneys  for
the  plaintiffs have appealed the decision. A  hearing on the appeal has not yet
been scheduled. The Company believes the eventual outcome of the litigation will
not have a material adverse effect on the Company's financial condition.

</TABLE>

    The  Underwriting  Agreement provides  that the  obligations of  the several
Underwriters thereunder  are subject  to approval  of certain  legal matters  by
counsel  and  to  various  other conditions.  The  nature  of  the Underwriters'
obligations is such that they are committed  to purchase and pay for all of  the
above shares of Common Stock if any are purchased.

    The Underwriters propose to offer the shares of Common Stock directly to the
public  at  the  public offering  price  set forth  on  the cover  page  of this
Prospectus, and at such  price less a  concession not in  excess of $[    ]  per
share  of  Common Stock  to  certain dealers  who  are members  of  the National
Association of Securities  Dealers, Inc.  The Underwriters may  allow, and  such
dealers  may re-allow, discounts  not in excess  of $[    ] per  share of Common
Stock to certain other dealers. After this offering to the public, the  offering
price and selling terms may be changed by the Representatives.

    The  Underwriters  have  been  granted  a  30-day  over-allotment  option to
purchase up  to an  aggregate  of 375,000  additional  shares of  Common  Stock,
exercisable  at the public offering price less the underwriting discount. If the
Underwriters exercise such over-allotment option, then each of the  Underwriters
will  have  a  firm  commitment,  subject  to  certain  conditions,  to purchase
approximately the same  percentage thereof  as the  number of  shares of  Common
Stock  to be purchased by it as shown  in the above table bears to the 2,500,000
shares of Common Stock offered hereby. The Underwriters may exercise such option
only to cover over-allotments made in connection with the sale of the shares  of
Common Stock offered hereby.

    Certain  of  the  Underwriters  and  selling  group  members  (if  any) that
currently act  as market  makers for  the Common  Stock may  engage in  "passive
market  making" in  the Common  Stock on Nasdaq  in accordance  with Rule 10b-6A
under the Exchange Act.  Rule 10b-6A permits, upon  the satisfaction of  certain
conditions,   underwriters  and   selling  group  members   participating  in  a
distribution  that  are  also  Nasdaq  market  makers  in  the  security   being
distributed  to engage in  limited market making  transactions during the period
when Rule 10b-6 under the Exchange  Act would otherwise prohibit such  activity.
Rule  10b-6A prohibits underwriters and selling group members engaged in passive
market making generally from entering a bid  or effecting a purchase at a  price
that exceeds the highest bid for those securities reported on Nasdaq by a market
maker  that is  not participating in  the distribution. Under  Rule 10b-6A, each
underwriter or selling group member engaged in passive market making is  subject
to  a daily net purchase limitation equal  to 30% of such entity's average daily
trading volume  during  the two  full  consecutive calendar  months  immediately
preceding  the  date  of the  filing  of  the registration  statement  under the
Securities Act pertaining to the security to be distributed.

    The foregoing shall not prohibit  any participants in the distribution  from
making  any purchases of securities otherwise  permitted by Rule 10b-6 under the
Exchange Act. Such exemptive relief also requires that such firms not engage  in
transactions for the purpose of creating actual or apparent active trading.

    The Company and the Underwriters have agreed to indemnify each other against
certain  liabilities,  including liabilities  under the  Securities Act,  and to
contribute in respect thereof.

    Stephen M.  McGrath,  a  Director  of the  Company,  is  an  Executive  Vice
President  of Oppenheimer &  Co., Inc. and  serves as Director  of its Corporate
Finance Department. Oppenheimer & Co.,  Inc. is currently assisting the  Company
in  its search  for a strategic  partner to develop  and market IMAGENT  US on a
worldwide basis. Oppenheimer & Co.,  Inc. and certain related parties  currently
hold  warrants  to acquire  approximately 174,000  shares  of Common  Stock. See
"Business -- Marketing."

    Lehman  Brothers  Inc.  assisted  the  Company  in  obtaining  the   License
Agreements  and has earned fees  payable by the Company  in connection with such
transactions.

    The Company and certain  of its officers and  directors of the Company  have
agreed  that they  will not,  directly or  indirectly, offer,  sell or otherwise
dispose of any  shares of  Common Stock or  any securities  convertible into  or
exchangeable  or exercisable for,  or any rights to  purchase or acquire, Common
Stock for a period  of 90 days  after the date of  this Prospectus, without  the
prior written consent of Lehman Brothers Inc.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors and Stockholders
Alliance Pharmaceutical Corp.

    We  have audited  the accompanying  consolidated balance  sheets of Alliance
Pharmaceutical Corp. and  subsidiaries as  of June 30,  1995 and  1994, and  the
related  consolidated statements  of operations, stockholders'  equity, and cash
flows for  each of  the two  years  in the  period ended  June 30,  1995.  These
financial  statements are  the responsibility  of the  Company's management. Our
responsibility is to express an opinion  on these financial statements based  on
our  audits. The  consolidated financial  statements of  Alliance Pharmaceutical
Corp. and subsidiaries for the year ended  June 30, 1993, were audited by  other
auditors  whose report, dated July 27, 1993, expressed an unqualified opinion on
those statements.

    We conducted  our  audits in  accordance  with generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit  also includes assessing  the accounting principles  used
and  significant estimates made by management, as well as evaluating the overall
financial  statement  presentation.  We  believe  that  our  audits  provide   a
reasonable basis for our opinion.

    In  our opinion,  the 1995 and  1994 financial statements  referred to above
present fairly, in all material respects, the consolidated financial position of
Alliance Pharmaceutical Corp. and  subsidiaries at June 30,  1995 and 1994,  and
the  consolidated results of their  operations and their cash  flows for each of
the two years in the  period ended June 30,  1995, in conformity with  generally
accepted accounting principles.

stockholders' equity  and  cash  flows  of  Alliance  Pharmaceutical  Corp.  and
Subsidiaries  (the "Company") for the year  ended June 30, 1993. These financial
statements  are   the   responsibility   of  the   Company's   management.   Our
responsibility  is to express an opinion  on these financial statements based on
our audit.

    We conducted  our  audit  in accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatements. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also  includes
assessing  the  accounting principles  used  and significant  estimates  made by
management, as well as evaluating the overall financial statement  presentation.
We believe that our audit provides a reasonable basis for our opinion.

    In  our opinion, such  consolidated financial statements  present fairly, in
all material respects,  the results  of the  Company's operations  and its  cash
flows  for the year ended  June 30, 1993, in  conformity with generally accepted
accounting principles.

1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    ORGANIZATION

    Alliance    Pharmaceutical   Corp.   ("Alliance")   and   its   subsidiaries
(collectively,  the  "Company")  are  engaged  in  identifying,  designing,  and
developing novel medical and pharmaceutical products.

    PRINCIPLES OF CONSOLIDATION

    The  consolidated financial statements include the accounts of Alliance, its
wholly owned  subsidiaries,  BioPulmonics,  Inc.  ("BioPulmonics")  and  Rosanin
Corporation,   and   its  majority-owned   subsidiaries,  Astral,   Inc.,  Talco
Pharmaceutical, Inc., and Applications  et Transferts de Technologies  Avancees.
All  significant intercompany  accounts and  transactions have  been eliminated.
Certain amounts in 1993, 1994, and 1995 have been reclassified to conform to the
current period's presentation.

    CASH, CASH EQUIVALENTS, AND SHORT-TERM INVESTMENTS

    Effective  July  1,  1994,  the  Company  adopted  Statement  of   Financial
Accounting Standards No. 115 ("FAS No. 115"), ACCOUNTING FOR CERTAIN INVESTMENTS
IN   DEBT  AND  EQUITY  SECURITIES.   Cash,  cash  equivalents,  and  short-term
investments consist of  highly liquid  debt instruments.  The Company  considers
instruments  purchased with an original  maturity of three months  or less to be
cash equivalents. Management has classified  the Company's cash equivalents  and
short-term  investments  as  available-for-sale securities  in  the accompanying
financial statements. Available-for-sale securities  are carried at fair  value,
with  the unrealized gains  and losses, net  of tax, reported  as a component of
stockholders' equity.

    INVENTORIES

    Inventories, which consist  primarily of  raw materials, are  stated at  the
lower of cost (first-in, first-out basis) or market.

    CONCENTRATION OF CREDIT RISK

    Cash, cash equivalents, and short-term investments are financial instruments
which  potentially  subject the  Company to  concentration  of credit  risk. The
Company invests  its excess  cash primarily  in U.S.  government securities  and
marketable  debt  securities  of financial  institutions  and  corporations with
strong credit  ratings.  The  Company has  established  guidelines  relative  to
diversification   and  maturities  to  maintain   safety  and  liquidity.  These
guidelines are reviewed periodically and modified to take advantage of trends in
yields and interest rates. The Company  has not experienced any material  losses
on its investments.

    PROPERTY, PLANT, EQUIPMENT, AND OTHER ASSETS

    Buildings,  furniture, and equipment are stated  at cost and depreciation is
computed using the straight-line method over the estimated useful lives of 4  to
25  years. Leasehold improvements  are amortized using  the straight-line method
over the shorter of the estimated useful lives of the assets or the lease  term.
Technology and patent rights are amortized using the straight-line method over 5
to 20 years.

    PURCHASED TECHNOLOGY

    The  purchased technology was primarily acquired  by virtue of the merger of
Fluoromed Pharmaceutical, Inc. into a subsidiary of the Company in fiscal  1989.
The   technology  acquired  is  the  Company's  core  perfluorochemical  ("PFC")
technology and it was valued based on an analysis of the present value of future
earnings anticipated from this technology  at that time. The Company  identified
alternative  future  uses  for  the PFC  technology,  including  the OXYGENT-TM-
(temporary blood substitute) and LIQUIVENT-REGISTERED TRADEMARK- (intrapulmonary
oxygen carrier) products.  Purchased technology also  includes $2.0 million  for
technology  capitalized  as  a  result of  the  acquisition  of  BioPulmonics in
December   1991.   Since   the   acquisition,   an   alternative   future    use

                   DECEMBER 31, 1994 AND 1995, IS UNAUDITED.)

1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
of  the acquired technology  has been pursued by  the Company. An intrapulmonary
drug delivery system  using the  PFC-based liquid  as a  carrier (or  dispersing
agent) is being developed by Alliance from the liquid ventilation technology.

    The  PFC technology  is the  basis for  the Company's  main drug development
programs and is being amortized over  a 20-year life. Amortization of  purchased
technology   is  included  in  research  and  development  expense.  Accumulated
amortization was $6,193,000,  $7,355,000, and  $7,936,000 at June  30, 1994  and
1995   and  December  31,  1995,  respectively.  The  technology  acquired  from
BioPulmonics is  being  amortized over  five  to seven  years,  and  accumulated
amortization  was $357,000, $500,000, and $671,000 at June 30, 1994 and 1995 and
December 31, 1995, respectively.

    The carrying value of purchased technology is reviewed periodically based on
the projected cash flows to be  received from license fees, milestone  payments,
royalties  and other  product revenues.  If such  cash flows  are less  than the
carrying value of the  purchased technology, the difference  will be charged  to
expense.

    OPTIONS

    The  Company has elected  to follow Accounting  Principles Board Opinion No.
25,  "Accounting  for  Stock   Issued  to  Employees"   (APB  25)  and   related
Interpretations in accounting for its employee stock options.

    RESEARCH AND DEVELOPMENT EXPENSES

    Research and development expenditures are charged to expense as incurred.

    NET LOSS PER COMMON SHARE

    Net  loss per common share is based on the weighted average number of common
shares outstanding during  the respective  periods and does  not include  common
stock  equivalents since their effect on the  net loss per common share would be
anti-dilutive.

    PREFERRED STOCK

    In fiscal  1995, in  conjunction  with a  license  agreement (see  Note  5),
Johnson  & Johnson  Development Corp. purchased  1.5 million  shares of Alliance
convertible preferred stock for $15.0 million. On or before June 30, 1998,  each
share  of the preferred stock  will be converted into  a number of common shares
based upon the lower of the average  price of Alliance common stock at the  time
of  conversion or $20  per share. Prior  to conversion, each  share of preferred
stock is entitled to one-half vote on matters on which shareholders are entitled
to vote. The preferred stock carries a cumulative annual cash dividend of  $0.50
per  share. As  of December 31,  1995, the  Company had recorded  as a liability
dividends payable totalling $969,000 on the Series A Preferred Stock.

    ACQUISITION OF BIOPULMONICS, INC.

    In December  1991,  the  Company  purchased all  the  outstanding  stock  of
BioPulmonics  in a transaction recorded using the purchase method of accounting.
The total purchase price was $3,055,000, payable in four installments.

    In June 1995, the  Company made the final  $1,000,000 payment to the  former
BioPulmonics'  stockholders to  complete the  acquisition, substantially  all of
which was  made  in  the  Company's  common  stock.  Since  the  acquisition  of
BioPulmonics,  an alternative  future use  of the  acquired technology  has been
pursued by  the  Company.  An  intrapulmonary drug  delivery  system  using  the
PFC-based  liquid  as a  carrier  (or dispersing  agent)  is being  developed by
Alliance from the  liquid ventilation technology.  Accordingly, the Company  has
capitalized purchased technology of $1,000,000.

5.  LICENSE AGREEMENT
    In August 1994, the Company executed a license agreement with Ortho Biotech,
Inc. and The R.W. Johnson Pharmaceutical Research Institute, a division of Ortho
Pharmaceutical Corporation (collectively referred to as "Ortho"), which provides
Ortho with worldwide marketing and, at its election, manufacturing rights to the
Company's  injectable perfluorochemical emulsions capable of transporting oxygen
for therapeutic use. Ortho will pay to  Alliance a royalty based upon its  sales
of  the products after commercialization. In addition, Ortho paid to Alliance an
initial license fee of $4.0  million and will make  other payments based on  the
achievement   of  certain  milestones.  Ortho   will  also  be  responsible  for
substantially all  the  remaining  costs of  developing  the  products.  Through
December  31, 1995,  the Company earned  research revenue of  $11.1 million from
Ortho, of which $2.0 million was included in accounts receivable. In conjunction
with the license agreement,  Johnson & Johnson  Development Corp. purchased  1.5
million  shares of  Alliance convertible preferred  stock for  $15.0 million and
obtained a  three-year warrant  to purchase  300,000 shares  of Alliance  common
stock at $15 per share.

</TABLE>

    Approximately $1,740,000 of the valuation allowance for deferred tax  assets
relates  to stock  option deductions  for 1995  which, when  recognized, will be
allocated to contributed capital.

    At June 30, 1995,  the Company had federal  and various state net  operating
loss  carryforwards of approximately $156,000,000 and $33,517,000, respectively.
The difference between the federal and state tax loss carryforwards is primarily
attributable to  the capitalization  of research  and development  expenses  for
California  tax purposes  and the  fifty percent  limitation on  California loss
carryforwards. The federal and various  state tax loss carryforwards will  begin
expiring  in fiscal 1998 and 1996, respectively, unless previously utilized. The
Company  also  has  federal  and  state  research  and  development  tax  credit
carryforwards  of $6,996,000 and $1,748,000,  respectively, for 1995, which will
begin expiring in fiscal 1998 unless previously utilized.

    Federal and California  tax laws  limit the  utilization of  income tax  net
operating  loss and credit carryforwards that arise prior to a change of control
of the Company.  However, the Company  believes that such  limitations will  not
have an impact on the utilization of the carryforwards.

7.  COMMITMENTS AND CONTINGENCIES
    The  Company leases certain office and  research facilities in San Diego and
certain equipment under  operating leases.  Provisions of  the facilities  lease
provide  for  abatement  of  rent during  certain  periods  and  escalating rent
payments during the lease  terms based on changes  in the Consumer Price  Index.
Rent expense is recognized on a straight-line basis over the term of the leases.

    Minimum  annual commitments related to operating  lease payments at June 30,
1995 are as follows:

7.  COMMITMENTS AND CONTINGENCIES (CONTINUED)
    Rent expense for fiscal 1995, 1994, 1993, and the six months ended  December
31,  1994  and  1995  was  $2,043,000,  $2,286,000,  $1,886,000,  $978,000,  and
$1,044,000, respectively.

    The Company entered into a loan and security agreement in August 1995  under
which  the Company received  $2.2 million. Amounts  borrowed under the agreement
are secured by fixed assets  and will be repaid  over three years commencing  in
September  1995. If certain financial covenants  are not satisfied, the note may
become due and payable.

    In December 1993, in order to obtain a commitment for a long-term supply  of
raw  material  for  both  clinical  trials  and  anticipated  future  commercial
production requirements, the Company entered  into an agreement with a  supplier
under which the Company was obligated to make payments to the vendor through May
1997  based, in part, upon the  achievement of certain milestones. The Company's
total minimum  future commitment  at June  30, 1995  and December  31, 1995  was
approximately  $3.2 and $2.2 million, respectively, some  or all of which may be
reimbursed to the Company by existing and future collaborative partners.

    During September 1992, the Company and certain of its officers and directors
were named as defendants in several lawsuits filed by certain shareholders.  The
actions  were consolidated into one class  action lawsuit. The complaint claims,
among other things, that the defendants failed to disclose certain problems with
two of the  Company's products under  development, which conduct  is alleged  to
have  falsely portrayed the Company's financial condition. In May 1995, the U.S.
District Court for the Southern District of California granted summary  judgment
in  favor of the Company, dismissing the lawsuit in its entirety. The plaintiffs
have filed a notice of intent to appeal the dismissal. The Company believes  the
eventual  outcome of the litigation  will not have a  material adverse effect on
the Company's financial condition.

8.  SUBSEQUENT EVENT (UNAUDITED)
    In February 1996, the  Company entered into a  license agreement (the  "HMRI
License  Agreement") with Hoechst Marion  Roussel, Inc. ("HMRI"), which provides
HMRI with worldwide marketing rights to  LIQUIVENT. The product will be  jointly
developed  by Alliance and  HMRI with HMRI responsible  for substantially all of
the remaining costs of development after March 31, 1996. HMRI will pay  Alliance
royalties  based on sales of the product after commercialization. In conjunction
with the HMRI License Agreement, HMRI  agreed to purchase 750,000 shares of  the
Company's  Series B Preferred Stock and 200,000 shares of its Series C Preferred
Stock for an  aggregate of  $22.0 million. HMRI  will also  receive a  five-year
warrant  to acquire 300,000 shares  of the Company's common  stock at $20.00 per
share. The Series B Preferred Stock is convertible into shares of the  Company's
common  stock upon the earliest of: (i)  the Company's common stock closing at a
price per share of at least $20.00 for twenty consecutive days; (ii) termination
of the HMRI License Agreement; or (iii) February 28, 2001. Each share of  Series
B  Preferred Stock will  be converted into  a number of  shares of the Company's
common stock based upon the lower of the average closing price of the  Company's
common  stock over the twenty  trading days preceding the  time of conversion or
$20.00 per share. The  Series C Preferred Stock  converts automatically on  June
30,  1997 into  a number  of shares  of the  Company's common  stock obtained by
dividing the average closing price of the Company's common stock over the twenty
trading days preceding  January 14, 1997  into $5.0 million.  Prior to June  29,
1997, HMRI may, if the HMRI License Agreement is terminated, redeem the Series C
Preferred Stock for $15.0 million, payable in cash or the Company's common stock
at  Alliance's election,  any time  on or  before the  expiration of  five years
following the redemption date.  In addition, HMRI will  pay Alliance an  initial
license  fee  and  will make  other  payments  upon the  achievement  of certain
milestones. The closing of  the transactions with HMRI  is subject to  obtaining
governmental approval under the Hart-Scott-

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Reference  is made  to Article VI  of the  By-Laws of the  Company (filed as
Exhibit 3(b) to the  Company's Annual Report  on Form 10-K  for the fiscal  year
ended  June  30,  1989)  and  to  Sections  721-727  of  the  New  York Business
Corporation Law, which, among  other things and  subject to certain  conditions,
authorize  the Company to  indemnify each of its  officers and directors against
certain liabilities and  expenses incurred  by such persons  in connection  with
claims  made by reason of  their being such officers  or directors. Reference is

ITEM 17.  UNDERTAKINGS.

    (a)  The  undersigned registrant  hereby  undertakes that,  for  purposes of
determining any liability under the Securities  Act of 1933, each filing of  the
registrant's  annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee  benefit
plan's annual report pursuant to 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.

    (b) 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 of 1933  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 of 1933 and  will be governed by  the final adjudication of  such
issue.

    (c) The undersigned registrant hereby 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 430A and contained in a
    form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4)
    or  497(h) under the  Securities Act of 1933  shall be deemed  to be part of
    this registration statement as of the time it was declared effective.

        (2) For the purpose  of determining any  liability under the  Securities
    Act  of  1933,  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.

parties to develop Products hereunder;

     b)   establish a subordinate governance structure to carry out the
provisions of this Agreement including establishing and organizing the PMT and
appointing a chairperson therefor or other subordinate committees or structures
to implement this Agreement, with the proviso that if the PMT is not
constituted or continued, any reference to such committee in this Agreement
shall be deemed to be a reference to the Steering Committee or to such other
committees or structures to which the Steering Committee may delegate
responsibility;

     c)   settle disputes or disagreements that are unresolved by the PMT or
other committees established by the Steering Committee unless otherwise
indicated in this Agreement;

of the Steering Committee no later than thirty (30) days prior to the scheduled
date of such meeting (unless such notice is waived), which notice shall contain

and HMRI having responsibility for meetings during the six (6) month period
beginning in July of each year;

     b)   shall hold special meetings on ten (10) days prior notice by either

     Either party may include such other representatives as they reasonably
deem appropriate at any meetings.

ALLIANCE and two members of the Steering Committee shall be selected by HMRI
from HMRI or its Affiliates.  Members of the Steering Committee shall be senior
officers and/or directors of their respective companies or Affiliates.  Members
of the Steering Committee shall serve in such capacity, on such terms and
conditions, and for such duration as shall be determined by the party selecting
such person for membership on the Steering Committee.  An alternate member
designated by a party may serve temporarily in the absence of a permanent
member designated by such party.

3.4  Actions to be taken by the Steering Committee pursuant to the terms of
this Agreement shall be taken following the unanimous vote of the members of
the Steering Committee (HMRI and ALLIANCE each having one (1) vote).  If the
Steering Committee fails to reach unanimous agreement, then HMRI shall have the
final decision subject to its obligations described in Section 2.5; provided
that prior to implementation of such decision the Chief Executive Officer of
ALLIANCE shall be entitled to meet and consult with the head of the Hoechst
Marion Roussel Pharmaceutical Group of Hoechst AG in a timely manner.

3.5  ALLIANCE and HMRI shall provide the Steering Committee, its members and
its authorized representatives with reasonable access during regular business

reasonably require in order to perform its obligations hereunder; provided that

Third Party, ALLIANCE or HMRI, as the case may be, may withhold access thereto
to the extent necessary to satisfy such obligation (such as ALLIANCE's
confidentiality obligations with Ortho Biotech, Inc. arising out of the license
agreement dated August 16, 1994).

3.6  For each committee subordinate to the Steering Committee constituted in
this Agreement, including the PMT, each of ALLIANCE and HMRI shall appoint and
replace its own representatives on the committee.  Each committee, including
the PMT, shall be comprised of representatives of each party, with the size of
each committee to be agreed upon from time to time.  Any party may designate an
alternate member for each committee to participate in the event one of the
party's regular committee members is unable to be present at a meeting.
Meetings of any committee may be called by either party with not less than ten
(10) working days notice to the other unless such notice is waived, and
meetings shall be held at the office of the party not calling the meeting,
unless otherwise agreed. Any meeting may be conducted in person or by telephone
conference, provided that any material decision made during a meeting shall be
evidenced by a conformed writing signed by at least one of the members of such
committee from each of the parties.  Each party will disclose to the other
proposed agenda items reasonably in advance of



                                       7
<PAGE>
each meeting of the applicable committee.  Each committee shall also be free to
consider any matters related to this Agreement which are within the scope of
its responsibilities.  Either party may include such other representatives as
they reasonably deem appropriate at any meetings.

3.7  Each party shall designate a single project coordinator whose primary
duties (until such time as the Steering Committee decides otherwise) will be to
oversee matters arising under the provisions of this Agreement.  Such project
coordinator will be responsible for the day-to-day worldwide coordination of
R&D Work, Preclinical Work, Clinical Work, Production Work and Regulatory Work
conducted under this Agreement and will serve to facilitate communication
between the parties relating to such work.

3.8  HMRI shall have the right to use an independent certified public
accountant reasonably acceptable to and approved by ALLIANCE, or HMRI's own
internal accountants, who shall have access to ALLIANCE's records during
reasonable business hours for the purpose of auditing R&D Work, Preclinical
Work, Clinical Work, Production Work and Regulatory Work expenditures under
this Agreement.  The audit under this Section may extend up to the three (3)
preceding years but this right may not be exercised more than once in any
calendar year and once a calendar year is audited it may not be reaudited.  The
results of the audit shall be disclosed to both parties, provided that the
independent accountant shall disclose to HMRI only information relating solely
to the accuracy and nature of expenditures made according to this Agreement.
For any overpayments greater than two (2) percent by HMRI found under this
Section, ALLIANCE shall pay HMRI the amount of overpayment, interest from the
time the amount was due at the then current prime rate as quoted in the Eastern
edition of  THE WALL STREET JOURNAL, and HMRI's out-of-pocket expenses.  For
any overpayments less than two (2) percent by HMRI found under this Section,
ALLIANCE shall pay HMRI the amount of overpayment.  The parties agree that no
costs or interest shall be awarded for any correction resulting from excess
estimated payments made from time to time by HMRI to ALLIANCE.

3.9  Subject to Section 4.4 herein, ALLIANCE shall remain responsible to Third
Parties for all financial payments payable for R&D Work, Preclinical Work,
Clinical Work, Production Work and Regulatory Work before April 1, 1996.  Any
such work contracted before the Effective Date but unpaid as of April 1, 1996
falls within the scope of this Agreement so long as such work was previously
disclosed in writing to HMRI per the notice provisions of this Agreement and
labeled as such.

ARTICLE 4 - PRODUCT DEVELOPMENT

4.1  The PMT shall be responsible for managing R&D Work, Preclinical Work,
Clinical Work, Production Work and Regulatory Work as well as related

in Appendix C and any future Plans authorized pursuant to this Agreement.  The
PMT and the Steering Committee will exercise the same oversight and control of
the Plans of Appendix B and Appendix C as if these Plans had been approved by
the Steering Committee hereunder, and said oversight and control will
specifically include directing changes and modifications to the Plans.  Subject
to Section 13.1, HMRI agrees to provide funding to ALLIANCE through June 30,
1997 of at least the amount set forth on Appendix B to develop the Products in
the United States and Canada and to make the estimated quarterly payments to
ALLIANCE set forth therein, which amounts will be solely applied to Plan Costs
and are not refundable. ALLIANCE agrees to utilize the funds for the
development of Products in the United States and Canada, and, in the event
notice of termination of this Agreement is not given prior to June 30, 1997,
any amount of such quarterly payments not previously applied to Plan Costs
shall be applied to ALLIANCE's worldwide Plan Costs incurred after June 30,
1997.  The parties agree that the Plans may change from time to time but the
HMRI financial commitment reflected in Appendix B shall not decrease.

If there are any proposed changes of whatever nature to Appendix B (other than
the level of financial commitment), and the PMT, or the Steering Committee fail
to reach unanimous agreement on said changes in accordance with the procedures
set forth herein, then HMRI will have the final decision with respect to said
changes.

     Either party may deliver to the PMT a list of proposed R&D Work,
Preclinical Work, Clinical Work, Production Work and Regulatory Work Plans for
the following calendar years, a description of each project and an estimated
budget for each project.  The proposed project description shall include a
detailed plan, an itemized estimate of costs and time required, the name of the
project leader, where the project will be carried out and the expected benefit.
The PMT will review the list of proposed Plans, revise the proposed projects as
it sees fit, and devise a R&D Work Plan, Preclinical Work Plan, Clinical Work
Plan, Production Work Plan and Regulatory Work Plan from the proposed projects
or from projects proposed by the PMT itself.  The PMT will establish a budget
for each of the Plans.  Such Plans and budgets therefor shall be submitted by
the PMT to the Steering Committee for approval.

4.4  HMRI shall pay all Plan Costs, and shall reimburse ALLIANCE for all of its
Plan Costs incurred after March 31, 1996.  Plan Costs include all out-of-
pocket, direct, and indirect expenses ordinary and necessary to the execution
of an approved Plan.  Out-of-pocket costs, which include payments to third
parties for supplies, materials, clinical travel, contracted outside services,
etc., shall be documented by records reasonably acceptable to HMRI.  Direct and
indirect expenses of research and/or development personnel (including, without
limitation, scientists, lab technicians, regulatory personnel, clinical support
personnel, and the like) shall be expressed in terms of the full-time
equivalent ("FTE") rate then in effect for ALLIANCE during the relevant time
period.  The FTE rate shall be calculated by determining the payroll cost for
ALLIANCE's scientific and technical personnel who allocate time among various
projects in ALLIANCE's ordinary course of business (including costs for fringe
benefits and payroll taxes) and an overhead rate, which includes all costs
other than out-of-pocket expenses for ALLIANCE's projects, including
LIQUIVENT-Registered Trademark-.  During the term of this Agreement, ALLIANCE
shall use its standard project costing and accounting system then in effect
in computing and tracking its direct and indirect costs. The objective of
reimbursing costs in the manner set forth herein is to reimburse Alliance
for its actual expenses in carrying out the Plan.

     a)   **











     b)   By October 1 of each year, the PMT will establish an overall project
budget for the upcoming calendar year broken down by major work areas/teams and
establish FTE labor and



                                      10
<PAGE>


overhead rates to be used as benchmarks to measure performance and
accountability.  At 6-month intervals, the PMT will add an additional 6-month
budget, thus maintaining a rolling 12-month budget.

4.5  Any sums due to ALLIANCE by HMRI pursuant to Articles 4, 8 or 9 shall be
billed by ALLIANCE each calendar quarter, substantiated by ALLIANCE with
suitable invoices and other reasonable documentation, including documentation
based on the actual FTE spending rates for labor and overhead, and paid by HMRI
within forty-five (45) days of receipt of such invoices.

4.6  The parties agree to promptly provide each other with copies of records,
reports, and regulatory filings showing a reasonable level of detail related to
their respective work in the United States, Japan, and each Major European
Country conducted under the terms of this Agreement, subject to the
confidentiality obligations described in Section 3.5.

     b)   the sum of **_______________________________ payable on June 30,
1997, **______________________________________________________________;

          _____________________________________________________________________
          __________________________________;

     e)   the sum of **______________________________________________payable
within thirty (30) days following the first commercial sale of a Product in
a Major European Country;

     f)   the sum of **______________________________________________payable
within thirty (30) days following the first commercial sale of a Product in
a second Major European Country; and

     g)   the sum of **_______________________________payable within thirty
(30) days following the first commercial sale of a Product in Japan.

     h)   the sum of **_____________________________________________________
____________________________________________________________________________
____________________________________________________________________________
____________________________________________________________________________.

5.2  The payments specified under Section 5.1 (a) through (g) shall be
allocated among the Patents as the parties reasonably agree as soon as
reasonably possible, and such payments shall not be creditable against
royalties or refundable.

5.3  In further consideration of the rights and licenses granted to HMRI under
Article 2 of this Agreement, HMRI shall pay to ALLIANCE the following royalties
based on the Net Sales of Products in the Territory:

   a)**
   b)**
   c)**
     **







                                      12
<PAGE>


     Upon the expiration of the royalty obligations of this Section 5.3 other
than as a result of termination of the Agreement **

                on a country-by-country basis, HMRI shall have a fully paid,
worldwide nonexclusive license solely to use, develop, manufacture, have
manufactured, market, sell, and distribute Products for the Field of Use and a
fully paid worldwide exclusive license to the trademark "LIQUIVENT".

5.4  Subject to the rights of ALLIANCE pursuant to this Agreement, including
but not limited to Sections 2.5 and 5.5, HMRI shall have the final decision
with respect to all aspects of commercialization or non-commercialization of
Products in any country in the Territory including but not limited to sales,
pre-marketing, marketing and distribution.

5.5  HMRI agrees that, during the term of this Agreement, it shall use its
reasonable best efforts to market Products throughout the Territory.
Reasonable best efforts shall mean that on a country-by-country basis HMRI
shall expend at least a similar level of corporate resources, including
employee time and money, as it would on an internally developed HMRI product,
taking into account the market potential of such products, the competitiveness
of the marketplace, the proprietary position of the Product and other relevant
factors.

5.6  In the event that a combination product is sold in a form containing a
Product and another product (which is not a Product) of HMRI, its Affiliates,
sublicensees or distributors, the Net Sales shall be calculated by multiplying
the sales price of the combination product by the fraction A/(A+B), where A is
the invoice price or, if none, then the fair market value of the Product, and B
is the invoice price or, if none, then the fair market value of the other
product.  For example, if the sales price of the combination product is $100
and the invoice prices (or fair market values, if applicable) of the Product
and the other product are $90 and $30, respectively, the Net Sales shall be $75
($100 x [$90/$120]).  Fair market value means the cash consideration which HMRI
or its Affiliates, sublicensees or distributors would realize from an
unaffiliated, unrelated buyer in an arm's length sale of an identical item sold
in the same quantity and at the same time and place of the transaction.  The
parties further agree to negotiate in good faith for an equitable determination
of Net Sales of Products in the event that HMRI sells Products in such a manner
that the Net Sales of same are not readily identifiable.

ARTICLE 6 - REPORTS AND RECORDS

6.1  HMRI shall keep and shall cause its Affiliates, sublicensees and
distributors to keep true and accurate records of sales of Products and Net
Sales and the royalties payable to ALLIANCE under Article 5 hereof and shall
deliver to ALLIANCE a written statement thereof on or before the sixtieth (60)
day following the end of each HMRI accounting quarter (or any part thereof in
the first or last calendar quarter of this Agreement) for such HMRI accounting
quarter.  Said



                                      13
<PAGE>


written statements shall set forth Net Sales and the calculation thereof on a
country by country basis for each Product and the royalties due thereon.

6.2  All royalty payments by HMRI to ALLIANCE with respect to Net Sales in any
currency other than U.S. Dollars shall be converted into U.S. Dollars at the
rate of exchange of such currency for U.S. Dollars for the calendar quarter for
which royalty payments are being remitted according to HMRI's normal procedures
for calculating same and, at or no later than the time the written statement
with respect to such royalty payment or is required to be given to ALLIANCE
pursuant to Section 6.1, shall be made by wire transfer to the ALLIANCE account
designated below, or such other account as ALLIANCE may designate from time to
time.  If the transfer or the conversion into U.S. Dollars in any such instance
is not lawful or possible, the payment of such part of the royalties due as is
necessary, shall be made by the deposit thereof, in such currency, to the
credit and account of ALLIANCE in any commercial bank or trust company of
ALLIANCE's choice located in that country.  Prompt notice of said deposit shall
be given by HMRI to ALLIANCE.

6.3  Any income or other taxes which HMRI or any of its Affiliates is required
to pay or withhold on behalf of ALLIANCE with respect to royalties and any
other monies payable to ALLIANCE under this Agreement shall be deducted from
the amount of such royalties and monies due.  HMRI or its Affiliate shall
furnish ALLIANCE with proof of such payments.  Any such tax required to be paid
or withheld shall be an expense of and borne solely by ALLIANCE.

6.4  ALLIANCE shall have the right to use an independent certified public
accountant reasonably acceptable to and approved by HMRI or its own internal
accountants who shall have access to HMRI and its Affiliates' and sublicensees
and distributors records during reasonable business hours for the purpose of
verifying the royalties payable as provided in this Agreement for the three (3)
preceding years, but this right may not be exercised more than once in any
calendar year, and once a calendar year is audited it may not be reaudited, and
said accountant shall disclose to ALLIANCE and HMRI only information relating
solely to the accuracy and nature of the royalty report and the royalty
payments made according to this Agreement.  For any underpayments greater than
two (2) percent by HMRI found under this Section, HMRI shall pay ALLIANCE the
amount of underpayment, interest from the time the amount was due at the then
current prime rate as quoted in the Eastern edition of  THE WALL STREET
JOURNAL, and ALLIANCE's out-of-pocket expenses.  For any underpayments less
than two (2) percent by HMRI found under this Section, HMRI shall pay ALLIANCE
the amount of underpayment.  Any overpayments by HMRI will be refunded to HMRI
or credited to future royalties, at HMRI's election.

6.5  All payments due hereunder shall be made to the designated bank account of
ALLIANCE as follows:

ARTICLE 7 - CONFIDENTIALITY

7.1  All confidential information transmitted by either party to the other
including all confidential information developed pursuant to this Agreement,
shall be identified as confidential and the receiving party shall, while this
Agreement is in effect and for five (5) years after termination thereof, make
no use of this information other than in furtherance of this Agreement and
shall use the same efforts to keep secret and prevent the disclosure of such
information to parties other than its Affiliates, sublicensees, agents,
officers, employees and representatives authorized to receive such information
as it would for its own confidential information except for such confidential
information that,

     a)   was known to the receiving party or its Affiliates or sublicensees at
the time of its disclosure and not previously subject to any obligation of
confidentiality at the time of its disclosure;

     b)   was generally available to the public or was otherwise part of the
public domain at the time of its disclosure;

     c)   became generally available to the public or became otherwise part of
the public domain after its disclosure and other than through any act or
omission of the receiving party or its Affiliates or sublicensees in breach of
this Agreement, or

     d)   became known to the receiving party or its Affiliates or sublicensees
after its disclosure (a) from a source other than the disclosing party
(including from independent development by the receiving party), (b) other than
from a Third Party who had an obligation to the disclosing party not to
disclose such information to others, and (c) other than under an obligation of
confidentiality, or

     e)   is disclosed by the receiving party pursuant to oral questions,
interrogatories, requests for information or documents, subpoena, or civil
investigative demand issued by a court or governmental agency; provided that
the receiving party notifies the other party immediately on receipt thereof and
that the disclosing party furnishes only that portion of the confidential
information that counsel advises is legally required.

7.2  Each receiving party or its Affiliates or sublicensees may disclose any of
the Know-How and confidential information to the extent such disclosure is
necessary to comply with applicable laws or regulations, or to make and use a
Product in accordance with the terms of this Agreement.

7.3  Each party recognizes the mutual interest in obtaining valid patent
protection.  Consequently, either party and its employees or consultants or any
other Third Party wishing to make a publication (including any oral disclosure
made without obligation of confidentiality) relating to work performed by such
party as part of the work performed under this Agreement (the "Publishing
Party") shall transmit to the other party (the "Reviewing Party") a copy of the
proposed written publication at least forty-five (45) days prior to submission
for publication, or an abstract of such oral disclosure at least fifteen (15)
days prior to submission of the abstract of the



                                      15
<PAGE>


oral disclosure, whichever is earlier.  The Reviewing Party shall have the
right (a) to propose modifications to the publication for patent reasons, (b)
to request a delay in publication of presentation in order to protect
patentable information, or (c) to request that the information be maintained as
a trade secret and, in such case, the Publishing Party shall not make such
publication.  Each party shall designate an individual to whom proposed
publications shall be directed and such individual shall be responsible for
obtaining the necessary internal approvals of the Reviewing Party.

7.4  If the Reviewing Party requests a delay as described in subsection 7.3(b)
the Publishing Party shall delay submission or presentation of the publication
for a period of up to ninety (90) days to enable patent applications protecting
each party's rights in such information to be filed.

7.5  Upon the receipt of written approval of the Reviewing Party or the
expiration of the applicable waiting period without comment, the Publishing
Party may proceed with the written publication or the oral presentation.

7.6  The parties hereto understand and agree that remedies at law may be
inadequate to protect against any breach of any of the provisions of this
Article 7 by either party or their employees, agents, officers or directors or
any other person acting in concert with it or on its behalf.  Accordingly, each
party shall be entitle to the granting of injunctive relief by a court of
competent jurisdiction against any action that constitutes any such breach of
this Article 7.  It is understood that such injunctive relief is intended
solely as provisional relief pending the dispute resolution procedures
described in Article 18 hereof.

7.7  Notwithstanding the foregoing, the right of any party to withhold or delay
consent to publish or delay publication shall be subject to any contractual
publication rights of Third Parties involved in research or clinical trials for
the Products.  The parties will use reasonable efforts to obtain the voluntary
consent of any Third Party with publication rights agreed to prior to the
Effective Date, to comply with the notice and timing requests in this Article 7
and will promptly review any publications delivered for review.

ARTICLE 8 - INVENTIONS AND PATENT PROSECUTION

8.1  All right, title and interest in all writings, inventions, discoveries,
improvements and other technology, whether or not patentable or copyrightable,
and any patent applications, patents or copyrights based thereon (collectively,
the "Inventions") that are discovered, made or conceived during and as a
result of the work performed under this Agreement solely by employees of
ALLIANCE or others acting on behalf of ALLIANCE ("Alliance Inventions") shall
be owned by ALLIANCE. All rights, title and interest in all Inventions that are
discovered, made or conceived during and as a result of the work performed
under this Agreement solely by employees of HMRI or others acting on behalf of
HMRI ("HMRI Inventions") shall be owned by HMRI.  All right, tittle and
interest in all Inventions that are discovered, made or conceived during and as
a result of the work performed under this Agreement  jointly by employees of
ALLIANCE and HMRI or others acting on their behalf (the "Joint Inventions")
shall be jointly owned by HMRI and ALLIANCE.  Each party shall promptly
disclose to the other party the making, conception or reduction to practice of
Inventions by employees or others acting on behalf of such party.



                                      16
<PAGE>


The parties acknowledge that the ownership rights set forth above are subject
to the license grants set forth in Article 2 and that any patent applications
or patents related to ALLIANCE Inventions or Joint Inventions shall become
Patents.

8.2  Each party represents and agrees that its employees and consultants shall
be obligated under a binding written agreement to assign to such party, or as
such party shall direct, all Inventions made or conceived during and as a
result of work performed under this Agreement by such employee or consultant.
In the case of non-employees working for other companies or institutions on
behalf of ALLIANCE or HMRI, ALLIANCE and HMRI, as applicable, shall use
reasonable efforts to obtain the right to license all Inventions made by such
non-employees on behalf of ALLIANCE or HMRI, as applicable, in accordance with
the policies of the company or institution employing such non-employee.
ALLIANCE and HMRI agree to undertake to enforce such agreements with employees
or others or such rights pertaining to non-employees (including, where
appropriate, by legal action) considering, among other things, the commercial
value of such Inventions.

8.3  ALLIANCE shall be responsible for the filing, prosecution (including
oppositions) and maintenance of the Patents.  For so long as any of the license
grants set forth in Article 2 remain in effect, ALLIANCE agrees to file and
prosecute and maintain the Patents in the countries in the Territory as listed
in Schedule 8.3; provided that the foregoing is subject to ALLIANCE's
reasonable business judgment.  ALLIANCE shall consult with HMRI and keep HMRI
fully informed of important issues relating to the preparation, filing,
prosecution and maintenance of such patent applications and patents, including
patent strategy with respect to both existing and future patent applications,
patents and patent extensions, and shall furnish to HMRI copies of documents
relevant to such preparation, filing, prosecution and maintenance sufficiently
prior to filing such document or making any payment due thereunder to allow for
review and comment by HMRI, and ALLIANCE shall seriously consider all such
comments.  ALLIANCE and HMRI shall mutually determine procedures for carrying
out the filing, prosecution (including oppositions) and maintenance, as
applicable, of patent applications and patents for all Joint Inventions and
shall each bear half of the cost thereof, and both parties shall be kept fully
informed of and consult and cooperate with respect to all actions taken with
respect thereto; provided that, if either party elects to not bear half the
cost of such activity with respect to a particular Joint Invention in a
particular country, then the other party may, at its sole expense and
discretion, undertake the filing, prosecution (including oppositions) and
maintenance of such patent or patent application in such country, and the party
not participating in such expenses shall assign its interest in such patent or
patent application in such country to the other party, including the rights to
receive and collect from third parties any royalties and damages for future or
past infringement, but reserving a perpetual royalty-free non-exclusive license
in such country (without the right to sublicense and subject to any limitations
imposed by this Agreement) to use such Joint Invention to make, have made, use,
distribute for sale and sell any products covered by such patent covering such
Joint Invention.  The non-participating party will cooperate with the other
party, at the other party's expense, as necessary to enable the other party to
establish and protect its rights under this Section 8.3.

     If ALLIANCE elects not to continue to seek or maintain patent protection
on any Patent in any country in the Territory, HMRI shall have the right, at
its option, but in the name of



                                      17
<PAGE>


ALLIANCE and at HMRI's expense, to file, prosecute (including oppositions) and
maintain such patent applications and patents as ALLIANCE shall have previously
filed in at least one country, provided, however, that the rights of the
parties with respect to any such Patent shall in all other respects be as
described in this Agreement.  ALLIANCE will advise HMRI of all decisions taken
with respect to any such election in a timely manner in order to allow HMRI to
protect its rights under this Section 8.3.

8.4  Each party shall make available to the other party (or to the other
party's authorized attorneys, agents or representatives), its employees,
agents, subcontractors or consultants to the extent reasonably necessary or
appropriate to enable the appropriate party to file, prosecute and maintain
patent applications and resulting patents with respect to Inventions owned by a
party and for periods of time reasonably sufficient for such party to obtain
the assistance it needs from such personnel.  Where appropriate, each party
shall sign or cause to have signed all documents relating to said patent
applications or patents at no charge to the other party.

8.5  ALLIANCE shall notify HMRI of (i) the issuance of each Patent giving the
date of issue and patent number for each such patent, and (ii) each notice
pertaining to any Patent which it receives as patent owner pursuant to the Drug
Price Competition and Patent Term Restoration Act of 1984 (hereinafter called
the "Act"), or other similar laws now or hereafter in effect, or pursuant to
comparable laws or regulations in other countries in the Territory.  The
parties shall cooperate with each other in applying for patent term extensions
(including Supplementary Protection Certificate in European Community
Countries) where applicable in any country of the Territory.  ALLIANCE shall
also notify HMRI of each application filed for patent term extension, any
allegations of failure to show due diligence and all awards of patent term
extensions with respect to the Patents.  Such notices shall be given promptly,
but in any event within twenty (20) business day after receipt of each such
notice pursuant to the Act (or comparable laws or regulations in other
countries in the Territory).  ALLIANCE shall notify HMRI of each filing for
patent term restoration under the Act (or comparable laws or regulations in
other countries in the Territory), any allegations of failure to show due
diligence and all awards of patent term restoration (extensions) with respect
to the Patents.

8.6  Except as otherwise expressly provided in this Agreement, under no
circumstances shall a party hereto, as a result of this Agreement obtain any
ownership interest in or other right to any technology, know-how, patents,
pending patent  applications, products, or biological material of the other
party, including items owned, controlled or developed by the other party, or
transferred by the other party to said party, at any time pursuant to this
Agreement.  It is understood and agreed that this Agreement does not grant HMRI
any license or other right in the Patents licensed for use, other than the use,
development, manufacture, marketing, sale and distribution of Products in the
Field of Use covered by the Patents.

ARTICLE 9 - INFRINGEMENT

9.1  ALLIANCE and HMRI shall each promptly, but in any event no later than ten
(10) business days after receipt of notice of such action, notify the other in
writing of any patent nullity actions, any declaratory judgment actions or any
alleged or threatened infringement of patents or patent applications or
misappropriation of intellectual property comprising the Patents or if either



                                      18
<PAGE>


party, or any of their respective Affiliates, shall be individually named as a
defendant in a legal proceeding by a Third Party alleging infringement of a
patent or other intellectual property right as a result of the manufacture,
production, use, development, manufacturing, marketing, selling or distribution
of Products, or of any other information or notification regarding the Patents.

9.2  HMRI shall have the first right to respond to, defend or prosecute any
actions, challenges, infringements, misappropriations or proceeding by a Third
Party alleging infringement described in Section 9.1.  In the event HMRI elects
to do so, ALLIANCE will cooperate with HMRI and its legal counsel, join in such
suits as may be brought by HMRI, and be available at HMRI's reasonable request
to be an expert witness or otherwise to assist in such proceedings.  HMRI will
cooperate with ALLIANCE and its legal counsel and keep ALLIANCE and its counsel
reasonable informed at all times as to the status of HMRI's response or
defense.

9.3  HMRI will not settle any suit or claim involving the Patents in a manner
that would compromise any rights of ALLIANCE without obtaining the prior
written consent of ALLIANCE.

9.4  In the event that HMRI elects to respond to, defend or prosecute any
actions, challenges, infringements, misappropriations or proceeding by a Third
Party alleging infringement described in Section 9.1, then:  (i) legal fees and
other costs and expenses of HMRI associated with such response or defense shall
be paid by HMRI; (ii) legal fees and other costs and expenses associated with
such response or defense incurred by ALLIANCE at HMRI's request, shall be paid
by ALLIANCE; (iii) costs of acquiring Third Party patents or licenses and any
settlement, court award, judgment or other damages will be **__________________;
and (iv) amounts recovered from Third Parties in connection with such
response or defense shall first be applied, **__________________________________
________________________________________________________________________________
_______________________________________________________________________________.
HMRI shall advance all costs required to be paid by ALLIANCE pursuant to
clauses (ii) and (iii) of this subsection 9.4 and shall recover such advanced
costs through credits against up to **  of the royalties otherwise payable by
HMRI to ALLIANCE hereunder, until the amount so advanced by HMRI is fully
recovered.  ALLIANCE shall have no obligation to repay HMRI any amounts
previously paid by HMRI to ALLIANCE hereunder to cover such costs.  **______
____________________________________________________________________________
____________________________________________________________________________

9.5  In the event that HMRI elects not to respond to, defend or prosecute any
actions, challenges, infringements, misappropriations or proceeding by a Third
Party alleging infringement described in Section 9.1 within sixty (60) days of
becoming aware of or being notified of such actions, challenges, infringements,
misappropriations or proceedings or abandons such response, then, in such
event, ALLIANCE shall have the option to do so at ALLIANCE's sole cost,
provided that HMRI shall cooperate with and provide assistance to ALLIANCE at
HMRI's expense.  All amounts so recovered from any Third Party shall be
retained by ALLIANCE,



                                      19
<PAGE>


subject to reimbursement of both parties for expenses and ALLIANCE shall have
no further obligations to HMRI with respect to the response or defense thereof;
provided further that the royalty rate payable by HMRI shall not be adjusted
downward due to an adverse judgment.

9.6  In the event that ALLIANCE and HMRI determine that it is necessary or
desirable for HMRI to acquire any Third Party patent or license in connection
with the development or manufacture of Products covered by the Patents in the
Territory, **_______________________________________________________________

ALLIANCE hereby grants to HMRI a worldwide exclusive royalty-free license to
the "LIQUIVENT" trademark in connection with the sale of Products in the
Territory for the term of this Agreement, and thereafter unless this Agreement

ARTICLE 13 - TERMINATION

13.1 Notwithstanding any other provision herein, HMRI can, prior to NDA
approval, terminate this Agreement on a country by country basis in its
entirety upon one (1) month written notice to ALLIANCE.  After NDA approval of
a Product and prior to first marketing of said Product, HMRI can terminate this
Agreement on a country by country basis upon two (2) months written

notice to ALLIANCE.  After the sale of a Product, HMRI can terminate this
Agreement on a country by country basis upon three (3) months written notice to
ALLIANCE.

13.2 Failure by HMRI or ALLIANCE to comply with any of the respective material
obligations and conditions contained in this Agreement shall entitle the other
party to give the party in default notice requiring it to cure such default.
If such default is not cured within ninety (90) days (thirty (30) days in case
of a monetary payment default) after receipt of such notice, the notifying
party shall be entitled (without prejudice to any of its other rights conferred
on it by this Agreement) to terminate this Agreement or in the event of an
uncured material breach by ALLIANCE, effect the rights of HMRI set forth in
Section 13.5 by giving a notice to take effect immediately.   Notwithstanding
the foregoing, in the event of a non-monetary default, if the default is not
reasonably capable of being cured within the ninety (90) day cure period by the
defaulting party and such defaulting party is making a good faith effort to
cure such default, the notifying party may not terminate this Agreement,
provided however, that the notifying party may terminate this Agreement if such
default is not cured within one hundred eighty (180) days of such original
notice of default.  The right of either party to terminate this Agreement as
hereinabove provided shall not be affected in any way by its waiver of, or
failure to take action with respect to any previous default.

13.3 In the event that one of the parties hereto shall go into liquidation, a
receiver or a trustee be appointed for the property or estate of that party and
said receiver or trustee is not removed within sixty (60) days, or the party
makes an assignment for the benefit of creditors (collectively, a "Bankruptcy
Event"), and whether any of the aforesaid Bankruptcy Events be the outcome of
the voluntary act of that party, or otherwise, the other party shall be
entitled to terminate this Agreement (or in the event ALLIANCE suffers such a
Bankruptcy Event, HMRI may effect its rights described in Section 13.5
forthwith by giving a written notice to the first party.

13.4 In the event that this Agreement is terminated in its entirety HMRI will:

     a)   deliver to ALLIANCE the Know-How and assign to ALLIANCE its rights in
said Know-How or Patents, if any, and any rights to ALLIANCE's trademarks,
excluding any Know-How or patents related to the manufacture of raw materials,
including, but not limited to, perfluorochemicals;

     b)   not use the Know-How as long as it has to be kept confidential

patents related to the manufacture of raw materials, including, but not limited
to, perfluorochemicals;

     e)   make all payments accrued under this Agreement prior to the effective

     g)   transfer to ALLIANCE responsibility for and control of ongoing work
of HMRI, Affiliates and Third Parties in an expeditious and orderly manner with
the costs for such work assumed by ALLIANCE as of the date of notice.

13.5 In the event of a Bankruptcy Event or a material default described in
Section 13.2 by ALLIANCE (which default is not cured as provided therein), HMRI
may elect in lieu of terminating this Agreement to declare the license granted
pursuant to this Agreement to be irrevocable.  From the date of receipt of
notice of such election, ALLIANCE shall have no further rights or obligations
under this Agreement, except that ALLIANCE may enforce any financial
obligations of HMRI, including those arising under Articles 4 and 5 herein
before or after such election; provided that if such election occurs prior to
commercial sales of Products, any additional reasonable costs incurred by HMRI
to commercialize the Products as a result of such election, shall be credited
against amounts payable by HMRI to ALLIANCE.

13.6 Upon termination of this Agreement in its entirety, ALLIANCE shall have
ninety (90) days to exercise an option to purchase all or any portion of the
inventory of Products owned by HMRI or its Affiliates upon such termination at
a price equal to HMRI's or its Affiliates' costs for such inventory.  Such
option shall be exercised by ALLIANCE in writing.  Within thirty (30) days of
such exercise, HMRI shall ship at ALLIANCE's cost and direction such inventory
to ALLIANCE.  ALLIANCE shall have forty-five (45) days to determine whether the
inventory complies with the Specifications (as defined in the Supply
Agreement).  If the inventory complies with the Specifications, ALLIANCE shall
pay for such inventory within forty-five (45) days of approval.  If such

countries (but not terminated in its entirety), HMRI will with respect to such
country:

     a)   deliver to ALLIANCE the Know-How and assign to ALLIANCE its rights in
said Know-How or Patents if any, excluding any Know-How or patents related to
the manufacture of raw materials, including, but not limited to,
perfluorochemicals;

     b)   not use the Know-How as long as it has to be kept confidential
pursuant to Article 7 hereof in such country, excluding any Know-How related to
the manufacture of raw materials, including, but not limited to,
perfluorochemicals;

     c)   not infringe any of the Patents in such country, excluding patents
related to the manufacture of raw materials, including but not limited to,
perfluorochemicals;

     d)   grant to ALLIANCE a non-exclusive, royalty free license to any
patents or Know-How owned or controlled by HMRI or its Affiliates which is

     2.   REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company hereby
represents and warrants to HMRI that:

<PAGE>


     2.1  ORGANIZATION AND CORPORATE POWER. The Company is a corporation duly
organized, validly existing and in good standing under the laws of the State of
New York and is qualified to do business as a foreign corporation in each
jurisdiction where failure to qualify would have a materially adverse effect on
the business or properties of the Company. The Company has full power and
authority to own its property, to carry on its business as presently conducted
and to carry out the transactions contemplated hereby. The copies of the
Certificate of Incorporation, Certificate of Amendment and Bylaws of the
Company, as amended to date, which have been furnished to HMRI by the Company,
are correct and complete.

     2.2  AUTHORIZATION. The Company has full power to execute, deliver and
perform this Purchase Agreement, the License Agreement between the Company and
HMRI attached hereto as Exhibit C (the "License Agreement") and each other
agreement entered into by the Company in connection with this Purchase
Agreement, and each such agreement has been duly executed and delivered by the
Company and is the legal, valid and, assuming due execution by the other
parties hereto and thereto, binding obligation of the Company, enforceable in
accordance with its terms, subject to applicable bankruptcy, insolvency,
moratorium, reorganization or similar laws affecting creditors' rights
generally, and to general equitable principles. The execution, delivery and
performance of this Purchase Agreement, including the sale, issuance and
delivery of the Preferred Stock and the Warrants, and the License Agreement,
and each other agreement entered into by the Company in connection with this
Purchase Agreement, has been duly authorized by all necessary corporate action
of the Company.

     2.3  CAPITALIZATION.     The entire authorized capital stock of the
Company consists of 50,000,000 shares of common stock, $0.01 par value per
share (the "Common Stock"), of which 24,916,691 shares are issued and
outstanding on December 31, 1995, and 5,000,000 shares of preferred stock,
$.01 par value, of which (i) 1,500,000 have been designated Series A
Preferred Stock and are issued and outstanding, (ii) 750,000 have been

shares of such preferred stock are issued or outstanding. The shares of
Common Stock outstanding are duly authorized, validly issued, fully paid and
nonassessable. No shares of Common Stock or preferred stock are held in the
Company's treasury. The Company has authorized and reserved 750,000 shares of
B Stock for issuance hereunder and 200,000 shares of C Stock for issuance

the same will be duly and validly authorized, executed and delivered by the
Company. The Company has authorized and reserved for issuance upon conversion

shares, until sold to the public generally pursuant to a registration
statement or Rule 144(k) promulgated under the Securities Act of 1933, as
amended (the "1933 Act"), are referred to herein as "Conversion Shares"). The
Conversion Shares and any shares of Common Stock issued upon the exercise of
an Option (as hereinafter defined) (such shares being referred to herein as
the "Option Shares") will, upon such issuance in accordance with the terms of
the Company's Certificate of Incorporation, as amended, or the Warrant
Certificate as the case may be, be duly authorized, validly issued and

encumbrances other than (i) those disclosed on Schedule 2.7, (ii) the lien of
current taxes not yet due and payable and (iii) possible minor liens and

     3.   REPRESENTATIONS AND WARRANTIES AND OTHER AGREEMENTS OF HMRI.

     3.1  REPRESENTATIONS AND WARRANTIES. HMRI hereby represents and warrants
that:

          a.   AUTHORIZATION. HMRI has full power and authority to execute,
deliver and perform this Purchase Agreement and to purchase the Shares and the
Warrants. Assuming due execution by the Company hereof and thereof, this
Purchase Agreement and each other agreement entered into by HMRI in connection
with this Purchase Agreement constitute the valid and legally binding
obligation of HMRI, enforceable against HMRI in accordance with their
respective terms, subject to applicable bankruptcy, insolvency, moratorium,
reorganization or similar laws affecting creditors' rights generally, and to
general equitable principles.

          b.   PURCHASE ENTIRELY FOR OWN ACCOUNT. It is HMRI's intention to
acquire the Shares, the Warrants, the Conversion Shares and the Option Shares
(collectively, the "Securities") for investment for HMRI's own account, not as
a nominee or agent and not with a view to the sale or other disposition of any
part thereof in violation of the 1933 Act. HMRI has no present intention of
selling, granting any participation in, or otherwise disposing of the same in
violation of the 1933 Act. HMRI does not have any contract, undertaking,
agreement or arrangement with any person to sell, transfer, or grant
participation to such person or to any third person, with respect to any of the
Securities.

          c.   RESTRICTIONS ON DISPOSITION. HMRI covenants that in no event
will it dispose of any of the Securities (other than pursuant to Rule 144
promulgated under the 1933 Act ("Rule 144") or pursuant to a registration
statement filed with the Securities and Exchange Commission (the "SEC")
pursuant to the 1933 Act) unless and until (i) HMRI shall have notified the
Company of the proposed disposition and shall have furnished the Company with a
statement of the circumstances surrounding the proposed disposition; and (ii)
HMRI shall have furnished the Company with an opinion of HMRI's counsel
reasonably satisfactory in form and substance to the Company and the Company's
counsel to the effect that (a) such disposition will not require registration
under the 1933 Act or compliance with any applicable state, local or foreign
law, or (b) appropriate action necessary for compliance with the 1933 Act and
any applicable state, local or foreign law has been taken. The restrictions on
transfer imposed by this Section 3.1(c) shall cease and terminate as to the
Securities when: (i) such securities shall have been effectively registered
under the 1933 Act and sold by the owner thereof in accordance with such
registration;

                                       7
<PAGE>

or (ii) an opinion of the kind described in the preceding sentence states that
all future transfers of such securities by the holder thereof would be exempt
from registration under the 1933 Act and compliance with any applicable state,
local or foreign law. Each certificate evidencing the Securities shall bear an
appropriate restrictive legend as set forth in Section 3.3 below, except that
such certificate shall not be required to bear such legend after a transfer
thereof if the transfer was made in compliance with Rule 144 or pursuant to a
registration statement or, if the opinion of counsel referred to above is
issued and provides that such legend is not required in order to establish
compliance with any provisions of the 1933 Act.

          d.   RECEIPT OF INFORMATION. HMRI has been furnished access to the
business records of the Company and all such additional information and
documents as such HMRI has requested and has been afforded an opportunity to
ask questions of and receive answers from representatives of the Company
concerning the terms and conditions of this Purchase Agreement and the purchase
of the Shares.

          e.   BROKERAGE. There are no claims for brokerage commissions or
finder's fees or similar compensation in connection with the transactions
contemplated by this Purchase Agreement based on any arrangement or agreement
made by or on behalf of HMRI, and HMRI agrees to indemnify and hold the Company
harmless against any damages incurred as a result of any such claims.

     3.2  FURTHER PROVISIONS REGARDING DISPOSITION.

          a.   TRANSFER TO AFFILIATES. Notwithstanding the provisions of
Section 3.1(c) above, no registration statement or opinion of counsel shall be
necessary for a transfer by HMRI to a subsidiary or affiliate (as defined
pursuant to the 1933 Act) of HMRI which is an accredited investor, if the
transferee makes the warranties set forth in Sections 3.1 (b) and (c) and
agrees in writing to be subject to the terms hereof, to the same extent as if
such transferee were HMRI hereunder.

          b.   NEW CERTIFICATES. Whenever the restrictions imposed by  Section
3.1(c) above shall terminate as herein provided, the holder of the securities
as to which such restrictions have terminated shall be entitled to receive from
the Company, without expense, one or more new certificates not bearing
restrictive legends and not containing any reference to the restrictions
imposed by this Purchase Agreement.

     3.3  LEGENDS. It is understood that, subject to Sections 3.1(c) and
3.2(b), the certificates evidencing the Shares, the Warrants, the Option Shares
and the Conversion Shares may bear substantially the following legends:

acquisition or disposition, on the open market or in private transactions, by
HMRI or any of its affiliates (including subsidiaries or other entities
controlled by HMRI) of any shares of the Common Stock or other equity
securities of the Company (or if HMRI or such affiliates shall direct any third
party to take any such actions on behalf of HMRI or such affiliates). Such
notice shall be transmitted to the Company by facsimile (with telephonic
notice) within ten (10) days after any such transaction, and shall specify the

convertible or exchangeable securities on the date hereof, or (ii) stock
options granted to employees, directors or consultants whenever granted under
the Company's stock option programs or incentive stock option plan) (an
"Issuance"), the Company hereby grants to HMRI the right (an "Option")
following any such Issuance, to purchase a number of shares of Common Stock as
set forth below. The consideration for shares issued pursuant to an Issuance
(the "Consideration") shall be deemed to be the per share amount of cash and
any other form of consideration received by the Company, meaning, in the case
of a public offering, the public offering price. The amount of any non-cash
Consideration shall be deemed to be the fair value of such non-cash
Consideration determined in good faith by the Company's Board of Directors.

     Pursuant to the Option, HMRI shall have the right to purchase the number
of additional shares of Common Stock (the "Option Number") determined by the
following formula:

                              NO = N ( 0.0288 )
                                    1

                                      12
<PAGE>


where N(O) is the Option Number and N(I) is the number of shares issued in the
Issuance.  If the Option Number would include a fractional share, it shall be
rounded to the nearest whole share.

     7.2. NOTICE OF ISSUANCE. Within ten (10) days after any Issuance, the
Company shall give written notice thereof to HMRI of the terms thereof,
including the Issuance Number, the Consideration and the Option Number of
shares related to such Issuance.

     7.3. PURCHASE PRICE. The price for each share purchased pursuant to the
Option shall be an amount (payable in cash) equal to the Consideration for a
share purchased under the Issuance.

     7.4. EXERCISE OF OPTION. The Option shall be exercised by written notice
to the Company, given within ten (10) days following receipt of written notice
of an Issuance pursuant to Section 7.2 above stating that it is HMRI's intent
to exercise the Option. The notice shall specify the number of shares for which
the Option is being exercised (up to the Option Number) and shall be
accompanied by payment in full of the exercise price for such shares.

     7.5. DELIVERY OF CERTIFICATES: REGISTRATION. Promptly after each exercise
of the Option, the Company shall cause to be delivered to HMRI a certificate or
certificates evidencing the shares purchased pursuant to the exercise of the
Option; provided, however, that HMRI shall be deemed to be the holder of record
of such shares as of the date of exercise of the Option with respect to such
shares. The Company may postpone the issuance and delivery of such shares upon
any exercise of the Option until (a) the admission of such shares to listing on
any stock exchange on which shares of the same class are then listed and (b)
the completion of such registration or other qualification of such shares under
any state or federal law, rule or regulation as the Company, in the reasonable
opinion of its counsel, shall determine to be necessary or advisable. Nothing
in this Section 7.5 shall be deemed to require that the Company file or amend a
registration statement under the 1933 Act.

     7.6. DIVIDENDS AND RECLASSIFICATION. If, following an Issuance but prior
to the exercise of, or expiration of the right to exercise, the Option relating
to such Issuance, there shall be declared payable to holders of record of the
Common Stock on a date prior to such exercise or expiration, or paid, a stock
dividend upon the Common Stock of the Company or if such stock shall be split-
up, combined, converted, exchanged (including by way of merger), reclassified,
or in any way substituted for (collectively, a "Dividend or Reclassification"),
the Option shall entitle HMRI upon the future exercise of the Option relating
to such Issuance to such number and kind of securities or other property,
subject to the terms of the Option, to which HMRI would have been entitled had
HMRI actually owned the Common Stock as to which the Option is then exercised
at the time of such Dividend or Reclassification; and the aggregate purchase
price upon the exercise of the Option relating to such Issuance shall be the
same as if the shares of Common Stock originally optioned were being purchased
as provided herein; provided that no fractions of shares shall be issued, the
aggregate purchase price shall be appropriately reduced on account of any
fractions not so issued and the purchase price shall in no event be less than
the par value of the Common Stock.


                                      13
<PAGE>

     7.7. RESERVATION OF COMMON STOCK. the Company hereby represents and
covenants with HMRI that it shall at all times reserve for issuance to HMRI
such number of shares of its Common Stock as will be sufficient to satisfy the
requirements of any Option.

     7.8. SUCCESSORS TO OPTION. The Option and all rights hereunder shall be
non-assignable and nontransferable, are intended solely for the benefit of
HMRI, and shall in no way inure to the benefit of its assignees or transferees.
Notwithstanding the foregoing, HMRI may assign or transfer the Option to any
corporation with which HMRI is merged or combined or to any corporation which
is a successor to or an affiliate of HMRI. The Company shall have the right to
require, as a condition precedent to such assignment or transfer, that the
assignee or transferee furnish such information as may in the opinion of
counsel for the Company be appropriate to permit such assignment or transfer in
light of the then applicable federal or state securities laws. As used in this
Agreement, the term "affiliate" shall have the meaning set forth in Rule 12b-2
under the Exchange Act, and the term "person" or "entity" shall mean any
individual, company, partnership, joint venture, association, corporation,
trust, government or agency thereof, or any other entity.

     7.9. INFORMATION FROM HMRI. The Company shall have the right to require,
as a condition precedent to the exercise of the Option, that HMRI furnish such
information (and representations comparable to those in Section 3.1) as may in
the reasonable opinion of counsel for the Company be appropriate to permit the
Company, in light of the then existence or non-existence of an effective
registration statement under the 1933 Act with respect to such shares, to issue
the shares in compliance with the provisions of that or any comparable act.

     8.   REGISTRATION OF COMMON STOCK.

     8.1  REGISTRATION. Upon conversion of the Preferred Stock, the Company
will use its best efforts to effect the registration under the 1933 Act on Form
S-3 or such other registration form as counsel to the Company deems appropriate
all of the Conversion Shares (to the extent issued prior to the effective date
of such registration and not previously registered, with respect to Conversion
Shares issued upon exercise of the Warrants) and Option Shares, or any shares
issued pursuant to stock dividends, stock splits or similar distributions upon
such Common Stock, Conversion Shares and Option Shares ("Registrable Stock").
For purposes of this Purchase Agreement, a "Holder" of any security means the
record or beneficial owner of such security or any permitted successor or
assignee thereof.

     8.2  REGISTRATION EXPENSES. The Company shall pay all expenses incurred in
effecting the registration of Registrable Stock pursuant to Section 8.1
including, without limitation, all federal and state registration,
qualification and filing fees, printing expenses, fees and disbursements of
counsel for the Company, blue sky fees and expenses, and the expense of any
special audits incident to or required by any such registration, but not
including underwriting discounts, commissions and expenses and fees of counsel
to the participating Holders.

                                      14
<PAGE>

     8.3  REGISTRATION PROCEDURES. If and whenever the Company is required by
the provisions of Section 8.1 to effect the registration of the Registrable
Stock under the 1933 Act, the Company will, as expeditiously as possible:

          (a)  prepare and file with the SEC a registration statement which
includes the Registrable Stock and use its best efforts to cause such
registration statement to become and remain effective until the distribution
described in the registration statement has been completed or until the
participating Holders can sell all such Registrable Stock pursuant to Rule 144;

          (b)  prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection therewith as
may be necessary to keep such registration statement effective and to comply
with the provisions of the 1933 Act with respect to the sale or other
disposition of Registrable Stock covered by such registration statement
whenever a Holder shall desire to sell or otherwise dispose of the same, but
only to the extent provided in this Section 8;

          (c)  furnish to each participating Holder (and to each underwriter,
if any, of Registrable Stock) such number of copies of a prospectus, including
a preliminary prospectus, in conformity with the requirements of the 1933 Act,
and such other documents, as such Holder may reasonably request in order to
facilitate the public sale or other disposition of the Registrable Stock;

          (d)  use its best efforts to register or qualify the Registrable
Stock covered by such registration statement under such state securities or
blue sky laws of such jurisdiction as each participating Holder shall
reasonably request and do any and all other acts and things which may be
necessary under such securities or blue sky laws to enable such Holder to
consummate the public sale or other disposition in such jurisdictions of the
Registrable Stock, except that the Company shall not for any purpose be
required to consent generally to service of process or qualify to do business
as a foreign corporation in any jurisdiction wherein it is not so qualified;

          (e)  before filing the registration statement prospectus or
amendments or supplements thereto, furnish to counsel selected by the
participating Holders copies of such documents proposed to be filed which shall
be subject to the reasonable approval of such counsel;

          (f)  enter into and perform its obligations under an underwriting
agreement, in usual and customary form, with the managing underwriter of such
offer;

          (g)  notify the participating Holders at any time when a prospectus
relating to any Registrable Stock covered by such registration statement is
required to be delivered under the 1933 Act, of the happening of any event as a
result of which the prospectus included in such registration statement, as then
in effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in light of the circumstances then existing and promptly
file such amendments and supplements as may be necessary so that, as thereafter
delivered to such Holders, such prospectus shall not include an untrue
statement of a material fact or omit to state a material fact required to

                                      15
<PAGE>


be stated therein or necessary to make the statements therein not misleading in
light of the circumstances then existing and use its best efforts to cause each
such amendment and supplement to become effective;

          (h)  furnish at the request of the participating Holders on the date
that such Registrable Stock is delivered to the underwriters for sale in
connection with a registration pursuant to this Section 8 an opinion, dated
such date, of the counsel representing the Company, for purposes of such
registration, in form and substance as is customarily given by company counsel
to the underwriters in an underwritten public offer addressed to the
underwriters, if any, and to such Holders, and (ii) a letter dated such date,
from the independent certified public accountants of the Company, in form and
substance as is customarily given by independent certified public accountants
to underwriters in an underwritten public offer, addressed to the underwriters
and to such Holders; and

          (i)  use its best efforts to cause all such Registrable Stock to be
listed on the securities exchange or the Nasdaq National Market, if any, on
which the Company's Common Stock is then listed.

     Upon receipt of any notice from the Company of the happening of any event
of the kind described in paragraph (g), the Holder will forthwith discontinue
disposition of such Registrable Stock covered by such registration statement or
prospectus until receipt of the copies of the supplemented or amended
prospectus, or until it is advised in writing by the Company that the use of
the applicable prospectus may be resumed, and has received copies of an
additional or supplemental filings which are incorporated by reference in such
prospectus, and, if so directed by the Company, the Holder will deliver to the
Company (at the Company's expense) all copies, other than permanent file copies
then in the Holder's possession, of the prospectus covering such Registrable
Stock current at the time of receipt of such notice.

     8.4  INDEMNIFICATION. In the event Registrable Stock is registered
pursuant to this Section 8:

          (a)  To the extent permitted by law, the Company will indemnify and
hold harmless each Holder of Registrable Stock which is included in a
registration statement filed pursuant to the provisions of this Agreement and
any underwriter (within the meaning of the 1933 Act) with respect to the
Registrable Stock, and each officer, director, employee and agent thereof and
each person, if any, who otherwise controls such Holder or underwriter (within
the meaning of the 1933 Act), against any losses or claims, damages, expenses
or liabilities, joint or several, to which they may become subject under the
1933 Act, the Exchange Act or other federal or state law, or otherwise, insofar
as such losses, claims, damages, expenses or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue or allegedly untrue
statement of any material fact contained in the registration statement for the
Registrable Stock, including any preliminary prospectus or final prospectus
contained therein or any amendments or supplements thereto, or any document
incident to the registration or qualification of any Registrable Stock, or
arise out of or are based upon the omission or alleged omission to state
therein a material fact required to be stated therein or allegedly necessary to
make the statements therein not misleading

                                      16
<PAGE>


 or arise out of any violation or alleged violation by the Company of the 1933
Act, the Exchange Act, any state securities law or any rule or regulation
promulgated under the 1933 Act, the Exchange Act or any state securities law;
and will reimburse such Holder, any underwriter, officer, director, employee,
agent or controlling person for any legal or other expenses reasonably incurred
by them in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that the indemnity agreement
contained in this Section 8.4(a) shall not apply to amounts paid in settlement
of any such loss, claim, damage, expense, liability or action if such
settlement is effected without the written consent of the Company, which shall
not be unreasonably withheld, nor shall the Company be liable under this
Section 8.4(a) to such Holder, such underwriter, officer, director, employee,
agent or controlling person for any such loss, claim, damage, expense,
liability or action to the extent that it arises out of, or is based upon, an
untrue statement or allegedly untrue statement or omission or alleged omission
made in connection with such registration statement, preliminary prospectus,
final prospectus, or amendments or supplements thereto, in reliance upon and in
conformity with information furnished in writing expressly for use in
connection with such registration by such Holder, such underwriter, officer,
director, employee, agent or such controlling person.

          (b)  To the extent permitted by law, each Holder of Registrable Stock
which is included in a registration statement filed pursuant to the provisions
of this Agreement will indemnify and hold harmless the Company, each of its
employees, agents, directors and officers, each person, if any, who controls
the Company within the meaning of the 1933 Act, and any underwriter (within the
meaning of the 1933 Act) against any losses, claims, damages, expenses or
liabilities to which the Company or any such person or underwriter may become
subject, under the 1933 Act, the Exchange Act or other federal or state law or
otherwise, insofar as such losses, claims, damages, expenses or liabilities (or
actions in respect thereof) arise out of, or are based upon any untrue or
allegedly untrue statement of any material fact contained in a registration
statement for the Registrable Stock, including any preliminary prospectus or
final prospectus contained therein or any amendments or supplements thereto, or
any document incident to the registration or qualification of any Registrable
Stock, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or allegedly
necessary to make the statements therein not misleading; in each case to the
extent that such untrue statement or allegedly untrue statement or omission or
alleged omission was made in such registration statement, preliminary
prospectus, or amendments or supplements thereto, in reliance upon and in
conformity with information furnished in writing by such Holder expressly for
use in connection with such registration; provided, however, that the indemnity
agreement contained in this Section 8.4(b) shall not apply to amounts paid in
settlement of any such loss, claim, damage, expense, liability or action if
such settlement is effected without the written consent of such Holder, which
shall not be unreasonably withheld; and such Holder will reimburse the Company
or any such person or underwriter for any legal or other expenses reasonably
incurred by the Company or any such person or underwriter in connection with
investigating or defending such loss, claim, damage, liability, expense or
action.

          (c)  Promptly after receipt by an indemnified party under this
Section 8.4 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against any indemnifying
party under this Section 8.4, notify the

                                      17
<PAGE>


indemnifying party in writing of the commencement thereof and generally
summarize such action. The indemnifying party shall have the right to
participate in and to assume the defense thereof with counsel mutually
satisfactory to the parties. An indemnifying party shall not have the right to
direct the defense of such an action on behalf of an indemnified party if such
indemnified party has reasonably concluded that there may be defenses available
to it that are different from or additional to those available to the
indemnifying party; provided, however, that in such event, the indemnifying
party shall bear the fees and expenses of only one (1) separate counsel for all
indemnified parties, such separate counsel to be reasonably satisfactory to the
indemnifying party. The failure to notify an indemnifying party promptly of the
commencement of any such action if prejudicial to the ability to defend such
action, shall relieve such indemnifying party of any liability to the
indemnified party under this Section 8.4, but the omission so to notify the
indemnifying party will not relieve such party of any liability that such party
may have to any indemnified party otherwise than under this Section.

          (d)  To the extent permitted by law, the indemnification provided for
under this Section 8.4 will remain in full force and effect regardless of any
investigation made by or on behalf of the indemnified party or any officer,
director or controlling person (within the meaning of the 1933 Act) of such
indemnified party and will survive the transfer of securities.

          (e)  If for any reason the foregoing indemnity is unavailable to, or
is insufficient to hold harmless an indemnified party, then the indemnifying
party shall contribute to the amount paid or payable by the indemnified party
as a result of such losses, claims, damages, liabilities or expenses (i) in
such proportion as is appropriate to reflect the relative benefits received by
the indemnifying party on the one hand and the indemnified party on the other
or (ii) if the allocation provided by clause (i) above is not permitted by
applicable law, or provides a lesser sum to the indemnified party than the
amount hereinafter calculated, in such proportion as is appropriate to reflect
not only the relative benefits received by the indemnifying party on the one
hand and the indemnified party on the other but also the relative fault of the
indemnifying party and the indemnified party as well as any other relevant
equitable considerations. Notwithstanding the foregoing, no underwriter, if
any, shall be required to contribute any amount in excess of the amount by
which the total price at which the securities underwritten by it and
distributed to the public were offered to the public exceeds the amount of any
damages which underwriter has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the 1933 Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The obligation of any underwriters
to contribute pursuant to this Section 8.4(e) shall be several in proportion to
their respective underwriting commitments and not joint.

     8.5  INFORMATION FROM HMRI. HMRI shall furnish to the Company in writing
any information regarding HMRI which the Company may reasonably request in
writing in connection with registration pursuant to this Section 8.

     2.   DIVIDENDS.

          2.1  SERIES B PREFERRED STOCK.     Before any dividends (other than
dividends payable in B Junior Stock) on any B Junior Stock shall be declared or
paid or set apart for payment, the holders of shares of Series B Preferred
Stock shall be entitled to receive cash dividends, when and as declared by the
Board of Directors, at the annual rate of one dollar ($1.00) per share, and no
more, payable annually on the first day of June in each year, to holders of
record on such date, not exceeding thirty (30) days preceding such dividend
payment date, as may be determined by the Board of Directors in advance of the
payment of each particular dividend.  The Series B Preferred Stock shall rank
on a parity with the Series A Preferred Stock as to dividends.  Such dividends
will be cumulative.

          Whenever, at any time, the full dividend as aforesaid for the current
dividend period shall have been paid or declared and set apart for payment on
the then outstanding Series B Preferred Stock, the Board of Directors may
declare dividends on any B Junior Stock, subject to the respective terms and
provisions (if any) applying thereto, and the Series B Preferred Stock shall
not be entitled to share therein.

          2.2  SERIES C PREFERRED STOCK.  Series C Preferred Stock shall not be
entitled to receive any dividends (other than dividends payable in B Junior
Stock or distributions pursuant to Section 5.6).

     3.   LIQUIDATION OR DISSOLUTION.

          3.1. RANK.     The Series B Preferred Stock and Series C Preferred

<PAGE>

                                                                              4

dissolution or winding-up and (ii) the holders of Series C Preferred Stock
shall be entitled to receive one cent ($.01) per share.  The amount of
dividends "accumulated" on any share of Series B Preferred Stock as at any
annual dividend date shall be deemed to be the amount of any unpaid dividends
accumulated thereon to and including such annual dividend date, whether or not
earned or declared, and the amount of dividends "accumulated" on any share of
Series B Preferred Stock as at any date other than an annual dividend date
shall be calculated as the amount of any unpaid dividends accumulated thereon,
whether or not earned or declared, at the rate of $.25 per share for each full
three-month period preceding such date and ending on September 1, December 1,
March 1 or June 1.  If, upon any such liquidation, dissolution or winding-up of
the Corporation, the assets distributable among the holders of Series B
Preferred Stock and Series C Preferred Stock (and any series of preferred stock
ranking in parity with the Series B Preferred Stock and Series C Preferred
Stock in respect of distributions upon liquidation, dissolution or winding-up
of the Corporation) shall be insufficient to permit the payment in full to such
holders of the preferential amount payable to such holders determined as
aforesaid, then the holders of Series B Preferred Stock and Series C Preferred
Stock (and any such series) will share ratably in any distribution of the
Corporation's assets in proportion to the respective preferential amounts that
would have been payable if such assets were sufficient to permit payment in
full of all such amounts.  After payment of the full amount of the liquidating
distribution to which the holders of Series B Preferred Stock and Series C
Preferred Stock are entitled, holders of B Junior Stock (other than Common
Stock) shall be paid any preferential amounts payable to such holders.
Thereafter, the holders of Series C Preferred Stock will not be entitled to any
further distributions and the holders of Series B Preferred Stock will share
PRO RATA with the holders of Common Stock (and the holders of Series A
Preferred Stock and any other preferred stock or B Junior Stock entitled to
share PRO RATA with Common Stock in liquidating distributions), based on the
number of shares of Common Stock into which the Series B Preferred Stock is
then convertible, in any further distribution of assets by the Corporation.
Under this Section 3, a distribution of assets in any dissolution, winding-up
or liquidation shall not include (a) any consolidation or merger of the
Corporation with or into any other corporation, (b) any dissolution,
liquidation or winding-up of the Corporation immediately followed by
reincorporation of a successor corporation or (c) a sale or other disposition
of all or substantially all of the Corporation's assets in consideration for
the issuance of equity securities of another corporation, provided that the
consolidation, merger, dissolution, liquidation, winding-up, sale or other
disposition (i) does not amend, alter, or change the preferences or rights of
the Series B Preferred Stock or Series C Preferred Stock or the qualifications,
limitations or restrictions thereof in a manner that adversely affects the
Series B Preferred Stock or Series C Preferred Stock and (ii) is done in
accordance with Sections 5.5, 5.6 or 5.7 hereof.

     4.   VOTING RIGHTS.

          4.1  Series B Preferred Stock.     The holders of Series B Preferred
Stock shall have the right to vote, together with the holders of all the
outstanding shares of Common Stock (and the holders of every other class or
series entitled to vote together with such holders) and not by class, except as
otherwise required by New York law, on all matters on which holders of Common
Stock shall have the right to vote.  Each holder of Series B Preferred Stock
shall have the right to cast one (1.0) vote for each share of Series B
Preferred Stock held by such holder.

Stock shall convert into fully paid and non-assessable shares of Common Stock
on the B Conversion Date at the B Conversion Rate as follows:

               5.1.1.    The Series B Preferred Stock shall convert into Common
Stock on the earlier of the following:

                    (a)  February 28, 2001;

                    (b)  Termination of the B License Agreement (unless
termination of the B License Agreement is as a result of the liquidation of the
Corporation, the appointment of a receiver or trustee for substantially all of
the property or assets of the Corporation, or the Corporation makes an
assignment for the benefit of creditors, in each case, in accordance with the B
License Agreement); or

                    (c)  At such time as the B Current Market Price per share
of Common Stock is equal to or greater than $20.00, subject to adjustment
pursuant to Section 5.5.

               5.1.2.    Upon conversion pursuant to Section 5.1.1(a) or (c),
the holders of Series B Preferred Stock shall receive accumulated dividends
paid in cash or, at the election of the Corporation, in Common Stock at the B
Current Market Price used to determine the B Conversion Rate upon conversion.
In the event of a conversion pursuant to Section 5.1.1(b), no accumulated
dividends shall be paid to the holders of Series B Preferred Stock.

          5.2. CONVERSION OF SERIES C PREFERRED STOCK.  The Series C Preferred
Stock shall convert into fully paid and non-assessable shares of Common Stock
at the C Conversion Rate on June 30, 1997, if notice of redemption pursuant to
Section 7.1 has not previously been given to the Corporation.

          5.3. CONVERSION NOTICE AND PROCEDURE.  Upon conversion of the Series
B Preferred Stock or Series C Preferred Stock, the Corporation shall send
written notice to the holders of Series B Preferred Stock or Series C Preferred
Stock, as the case may be.  Any notice of conversion to a holder of Series B
Preferred Stock shall contain the B Conversion Date, the B Conversion Rate and
the number of shares into which the holder's Series B Preferred Stock is
converted.  Any notice of conversion to a holder of the Series C Preferred
Stock shall contain the C Conversion Rate and the number of shares into which
the holder's Series C Preferred Stock is converted.  Upon conversion of Series
B Preferred Stock or Series C Preferred Stock, the shares so converted shall
have the status of authorized and unissued preferred stock, and the number of
shares of preferred stock which the Corporation shall have authority to issue
shall include the number of shares of Series B Preferred Stock or Series C
Preferred Stock so converted, as the case may be. Upon any conversion,
certificates representing the Series B Preferred Stock or Series C Preferred
Stock shall thereafter be deemed to represent the appropriate number of shares


<PAGE>

                                                                              6

of Common Stock into which such stock is converted.  After conversion the
holder of any shares of Series B Preferred Stock or Series C Preferred Stock so
converted shall deliver to the Corporation during regular business hours, at
such place as may be designated by the Corporation, the certificate or
certificates for the shares to be converted, duly endorsed or assigned in
blank, or to the Corporation (if required by it), accompanied by written notice
stating the name or names (with address) in which the certificate or
certificates for the shares of Common Stock are to be issued.

          5.4. FRACTIONAL SHARES.  No fractional shares of Common Stock or
scrip shall be issued upon conversion of shares of Series B Preferred Stock or
Series C Preferred Stock.  If more than one share of Series B Preferred Stock
or Series C Preferred Stock shall be surrendered for conversion at any one time
by the same holder, the number of full shares of Common Stock issuable upon
conversion thereof shall be computed on the basis of the aggregate number of
shares so surrendered.  Instead of any fractional shares of Common Stock which
would otherwise be issuable upon any such conversion, the Corporation shall pay
a cash adjustment in respect of such fractional interest in an amount
determined on the basis of the then current fair market value of a share of
Common Stock as determined by the Board of Directors of the Corporation, in
good faith.  Fractional interests shall not be entitled to dividends, and the
holders thereof shall not be entitled to any rights as stockholders of the
Corporation in respect of such fractional interests.

          5.5. ADJUSTMENTS FOR SUBDIVISIONS, STOCK DIVIDENDS, COMBINATIONS, OR
CONSOLIDATIONS OF COMMON STOCK.

               5.5.1.    In the event the outstanding shares of Common Stock
shall be increased by way of stock issued as a dividend for no consideration or
subdivided (by stock split, or otherwise) into a greater number of shares of
Common Stock, the B Division Amounts then in effect shall, concurrently with
the effectiveness of such increase or subdivision, be proportionately
decreased.  In the event the outstanding shares of Common Stock shall be
combined or consolidated, by reclassification or otherwise, into a lesser
number of shares of Common Stock, the B Division Amounts then in effect shall,
concurrently with the effectiveness of such combination or consolidation, be
proportionately increased.

               5.5.2.    In the event the outstanding shares of Common Stock
shall be increased by way of stock issued as a dividend for no consideration or
subdivided (by stock split, or otherwise) into a greater number of shares of
Common Stock after January 14, 1997 and prior to the conversion of the Series C
Preferred Stock, the C Current Market Price then in effect shall, concurrently
with the effectiveness of such increase or subdivision, be proportionately
decreased.  In the event the outstanding shares of Common Stock shall be
combined or consolidated, by reclassification or otherwise, into a lesser
number of shares of Common Stock after January 14, 1997 and prior to the
conversion of the Series C Preferred Stock, the C Current Market Price then in
effect shall, concurrently with the effectiveness of such combination or
consolidation, be proportionately increased.

          5.6. OTHER DISTRIBUTIONS.


<PAGE>

                                                                             7

               5.6.1.    If for any reason, including without limitation a
merger or sale of assets transaction, the Corporation shall declare a
distribution payable in securities of the Corporation other than shares of B
Junior Stock, or in securities of other persons, evidences of indebtedness
issued by the Corporation or other persons, or assets (excluding cash
dividends) then, in each such case for the purpose of this Section 5.6.1, the
holders of the Series B Preferred Stock shall be entitled to a proportionate
share of such distribution as though they were the holders of the number of
shares of Common Stock of the Corporation into which their shares of Series B
Preferred Stock would be convertible as of the record date fixed for the
determination of the holders of Common Stock of the Corporation entitled to
receive such distribution.

               5.6.2.    If for any reason, including without limitation a
merger or sale of assets transaction, the Corporation shall after January 14,
1997 and prior to conversion of the Series C Preferred Stock declare a
distribution payable in securities of the Corporation other than shares of B
Junior Stock, or in securities of other persons, evidences of indebtedness
issued by the Corporation or other persons, or assets (excluding cash
dividends) then, in each such case for the purpose of this Section 5.6.2, the
holders of the Series C Preferred Stock shall be entitled upon conversion, if
any, to a proportionate share of such distribution (or, at the election of the
Board of Directors, to a cash payment equal to the fair market value on the
date of such distribution, as determined by the Board of Directors in their
reasonable discretion, of a proportionate share of such distribution) as though
they were the holders of the number of shares of Common Stock of the
Corporation into which their shares of Series C Preferred Stock would be
convertible as of the record date fixed for the determination of the holders of
Common Stock of the Corporation entitled to receive such distribution.

          5.7. REORGANIZATIONS AND RECAPITALIZATIONS.  If at any time or from
time to time there shall be a reorganization or recapitalization of the Common
Stock (other than a subdivision, combination or merger or sale of assets
transaction provided for in Section 5.5 or Section 5.6 above), then, as a
condition of such reorganization or recapitalization, provision shall be made
so that the holders of the Series B Preferred Stock or Series C Preferred Stock
shall thereafter be entitled to receive upon conversion of the Series B
Preferred Stock or Series C Preferred Stock, as the case may be, the number of
shares of stock or other securities or property of the Corporation or otherwise
to which a holder of Common Stock deliverable upon conversion would have been
entitled on such reorganization or recapitalization.  In any such case,
appropriate adjustment shall be made in the application of the provisions of
this Section 5 with respect to the rights of the holders of the Series B
Preferred Stock or Series C Preferred Stock after the reorganization or
recapitalization to the end that the provisions of this Section 5 (including
adjustment of the B Conversion Rate or C Conversion Rate and the B Division
Amounts then in effect and the number of shares receivable upon conversion of
the Series B Preferred Stock or Series C Preferred Stock) shall be applicable
after that event in as nearly an equivalent manner as may be practicable.

          5.8. RESERVATION OF SHARES.        The Corporation agrees that, so
long as any share of Series B Preferred Stock or Series C Preferred Stock shall
remain outstanding, the Corporation shall at all times reserve and keep
available, free from preemptive rights, out of its authorized capital stock,
for the purpose of issue upon conversion of the Series B Preferred Stock or
Series C Preferred Stock, as the case may be, the full number of shares of
Common Stock then


<PAGE>

                                                                              8

issuable upon conversion of all outstanding shares of Series B Preferred Stock
or Series C Preferred Stock, as the case may be.  If the Common Stock shall be
listed on any national securities exchange, the Corporation at its expense
shall include in a listing application all of the shares of Common Stock
reserved for issuance upon conversion of the Series B Preferred Stock or Series
C Preferred Stock, as the case may be, (subject to issuance or notice of
issuance to the exchange) and will similarly apply for and use its best efforts
to procure the listing of any further Common Stock reserved for issuance upon
conversion of the Series B Preferred Stock or Series C Preferred Stock, as the
case may be, at any subsequent time as a result of adjustments in the B
Conversion Rate or the C Conversion Rate or otherwise.

          5.96.     VALIDITY OF SHARES. The Corporation agrees that it will
from time to time take all such actions as may be requisite to assure that all
shares of Common Stock which may be issued upon conversion of any share of the
Series B Preferred Stock or Series C Preferred Stock will, upon issuance, be
legally and validly issued, fully paid and non-assessable and free from all
taxes, liens and charges with respect to the issue thereof.

          5.10.     TAXES.    The Corporation will pay all taxes and other
governmental charges that may be imposed in respect of the issue or delivery
(but not transfer) of shares of Common Stock upon conversion of the Series B
Preferred Stock or Series C Preferred Stock.

          5.11.     ABANDONMENT OF ACTION.   If the Corporation shall take a
record of the holders of its Common Stock for the purpose of entitling them to
receive a dividend or distribution requiring an adjustment pursuant to Section
5 and shall, thereafter and before the distribution to stockholders thereof,
legally abandon its plan to pay or deliver such dividend or distribution, then
thereafter no adjustment to the holders of Series B Preferred Stock or Series C
Preferred Stock shall be required by reason of the taking of such record and
any such adjustment previously made in respect thereof shall be rescinded and
annulled.

          5.12.     NOTICE PROVISIONS.

               5.12.1.   Whenever an adjustment is required pursuant to Section
5 hereof, the Corporation shall forthwith deliver to the holders of Series B
Preferred Stock or Series C Preferred Stock, as the case may be, a certificate
signed by an officer of the Corporation, setting forth, in reasonable detail,
the event requiring the adjustment, the method by which such adjustment was
calculated and the adjustments made.

               5.12.2.     In case the Corporation shall propose (a) to pay any
dividend payable in stock of any class to the holders of B Junior Stock or to
make any other distribution to the holders of its Common Stock, (b) to offer to
the holders of its Common Stock rights to subscribe for or to purchase any
Convertible Securities, Common Stock or shares of stock of any class or any
other securities, rights or options, (c) to effect any reclassification of its
Common Stock (other than a reclassification involving only the subdivision or
combination of outstanding shares of Common Stock), (d) to effect any capital
reorganization, (e) to effect any consolidation, merger or sale, transfer or
other distribution of all or substantially all its property, assets or
business, or (f) to effect the liquidation, dissolution or winding-up of the
Corporation, then, in each such case, the Corporation shall give to each holder
of Series B Preferred Stock or Series C

<PAGE>

                                                                             9

Preferred Stock a notice of such proposed action, which shall specify the date
on which a record is to be taken for the purposes of such stock dividend,
distribution or rights, or the date on which such reclassification,
reorganization, consolidation, merger, sale, transfer, disposition,
liquidation, dissolution or winding-up is to take place and the date of
participation therein by the holders of Common Stock, if any such date is to be
fixed, and shall also set forth such facts with respect thereto as shall be
reasonably necessary to indicate the effect of such action on the Common Stock
and the B Conversion Rate, C Conversion Rate, and the B Division Amounts after
giving effect to any adjustment which will be required as a result of such
action.  Such notice shall be so given in the case of any action covered by (a)
or (b) above at least ten (10) days prior to the record date for determining
holders of the Common Stock for purposes of such action and, in the case of any
other such action, at least ten (10) days prior to the date of the taking of
such proposed action or the date of participation therein by the holders of
Common Stock, whichever shall be the earlier.

     6.   NO PRE-EMPTIVE RIGHTS.   No holder of Series B Preferred Stock or
Series C Preferred Stock shall have any pre-emptive or preferential right of
subscription to any shares of stock of the Corporation, or to options, warrants
or other interests therein or therefor, or to any obligations convertible into
stock of the Corporation, issued or sold, or any right of subscription to any
thereof other than such, if any, as the Board of Directors, in its discretion,
from time to time may determine and at such price or prices as the Board of
Directors from time to time may fix pursuant to the authority conferred by the
Corporation's Certificate of Incorporation.

     7.   Redemption of Series C Preferred Stock.

          7.1  Redemption at the Option of the Holders of Series C Preferred
Stock.  Beginning October 1, 1996 and ending on June 29, 1997, upon the request
of the holders of one hundred percent (100%) of the Series C Preferred Stock,
the Corporation shall redeem all, but not less than all, of the outstanding
Series C Preferred Stock; provided that such election may only be given within
the five (5) day period following the effective date of termination of the B
License Agreement.  Notice of such election signed by the holders of one
hundred percent (100%) of the Series C Preferred Stock shall be delivered to
the Corporation one (1) day in advance of the day designated for such
redemption (herein called the "redemption date").  The amount payable to
holders of Series C  Preferred Stock as of the redemption date shall be $75.00
per share.

          7.2. Within forty-five (45) days of the redemption date, the
Corporation shall pay to the holders of Series C Preferred Stock at their
respective addresses as the same shall appear on the books of the Corporation,
the amount due to such holders on such redemption.  Such amount shall be

note.  The promissory note shall accrue interest at a fluctuating rate equal to
the prime rate from time to time in effect, as quoted in the Eastern edition of
THE WALL STREET JOURNAL, and all principal and interest shall be due and
payable on June 30, 2002.  The Corporation may at any time pay all outstanding
amounts owed under the promissory note in cash or Common Stock.  If Common
Stock  is issued in payment of principal of or interest on such promissory note

                                  ARTICLE  II

                       DURATION AND EXERCISE OF WARRANT

     SECTION 2.01: DURATION OF WARRANT. Subject to the terms contained herein,
this Warrant may be exercised at any time after February 28, 1996, and before
5:00 P.M. New York time, on the Expiration Date (or, if such day is not a
Business Day, at or before 5:00 P.M. New York time, on the next following
Business Day). If this Warrant is not exercised at or before 5:00 P.M., New
York time, on the Expiration Date, it shall become void, and all rights
hereunder shall thereupon cease.  Notwithstanding anything to the contrary
herein, this Warrant shall become void, and all rights hereunder shall
thereupon cease upon termination of the License Agreement.

     SECTION 2.02: EXERCISE OF WARRANT. (a) The Warrantholder may exercise this
Warrant, in whole or in part, upon surrender of this Warrant with the Sub-
scription Form hereon duly executed, to the Company at its corporate office in
San Diego, California, together with the full Exercise Price for each share of
Common Stock to be purchased in lawful money of the United States, or by
certified check, bank draft or postal or express money order payable in United
States Dollars to the order of the Company and upon compliance with and subject
to the conditions set forth herein.



                                     - 3 -
<PAGE>



          (b) Upon receipt of this Warrant with the Subscription Form duly
executed and accompanied by payment of the aggregate Exercise Price for the
shares of Common Stock for which this Warrant is then being exercised, the
Company will cause to be issued certificates for the total number of whole
shares of Common Stock for which this Warrant is being exercised in such
denominations as are required for delivery to the Warrantholder, and the
Company shall thereupon deliver such certificates to the Warrantholder. If at
the time this Warrant is exercised, a registration statement is not in effect
to register under the Securities Act the Warrant Shares issuable upon exercise
of this Warrant, the Company may require the Warrantholder to make such
investment intent representations, and may place such legends on certificates
representing the Warrant Shares, as may be reasonably required in the opinion
of counsel to the Company to permit the Warrant Shares to be issued without
such registration.

          (c) In case the Warrantholder shall exercise this Warrant with
respect to less than all of the shares of Common Stock that may be purchased
under this Warrant, the Company will execute a new warrant certificate in the
form of this Warrant for the balance of the shares of Common Stock that may be
purchased upon exercise of this Warrant and deliver such new warrant
certificate to the Warrantholder.

          (d) The Company covenants and agrees that it will pay when due and
payable any and all taxes which may be payable in respect of the issue of this
Warrant or in respect of the issue of any Warrant Shares. The Company shall
not, however, be required to pay any tax imposed on income or gross receipts or
any tax which may be payable in respect of any transfer involved in the
issuance or delivery of this Warrant or of Warrant Shares in a name other than
that of the Warrantholder at the time of surrender and, until the payment of
such tax, shall not be required to issue such Warrant Shares.

                                  ARTICLE III

                     Adjustment of Shares of Common Stock

                       PURCHASABLE AND OF EXERCISE PRICE

The Exercise Price and the number and kind of Warrant Shares shall be subject
to adjustment from time to time upon the happening of certain events as
provided in this Article III.

     SECTION 3.01: MECHANICAL ADJUSTMENTS. (a) If at any time prior to the full
exercise of this Warrant, the Company shall (i) pay a dividend or make a dis-
tribution on its shares of Common Stock in shares of Common Stock (other than
cash dividends or distributions out of earnings); (ii) subdivide, reclassify or
recapitalize its outstanding Common Stock into a greater number of shares; or
(iii) combine, reclassify or recapitalize its outstanding Common Stock into a
smaller number of shares, the Exercise Price in effect at the time of the
record date of such subdivision, combination, reclassification or
recapitalization shall be proportionately adjusted so that the Warrantholder
shall be entitled to receive the aggregate number and kind of shares which, if
this Warrant had been exercised in full immediately prior to such time, he
would have owned upon such exercise and been entitled to receive upon such
dividend, subdivision, combination, reclassification or recapitalization. Such
adjustment shall be made successively whenever any event listed in this
paragraph 3.01(a) shall occur.



                                     - 4 -
<PAGE>



          (b) In case the Company shall hereafter fix a record date for making
a distribution to the holders of Common Stock of assets or evidences of its
indebtedness (excluding cash dividends or distributions out of earnings and
dividends or distributions referred to in paragraph (a) of this Section 3.01)
or Common Stock subscription rights, options or warrants for Common Stock or
Common Stock Equivalents, then in each such case the Exercise Price in effect
after such record date shall be adjusted to the price determined by multiplying
the Exercise Price in effect immediately prior thereto by a fraction, the
numerator of which shall be the total number of shares of Common Stock
outstanding at such time multiplied by the current market price per share of
Common Stock (as defined in paragraph (d) of this Section 3.01), less the fair
market value (as determined by the Company's Board of Directors) of said assets
or evidences of indebtedness so distributed or of such Common Stock
subscription rights, option and warrants or of such Common Stock Equivalents,
and the denominator of which shall be the total number of shares of Common
Stock outstanding at such time multiplied by such current market price per
share of Common Stock. Such adjustment shall be made successively whenever the
record date for such a distribution is fixed and shall become effective
immediately after such record date.

          (c) Whenever the Exercise Price payable upon exercise of each Warrant
is adjusted pursuant to paragraphs (a) or (b) of this Section 3.01, the Warrant
Shares shall simultaneously be adjusted by multiplying the number of Warrant
Shares then issuable upon exercise of each Warrant by the Exercise Price in
effect on the date thereof and dividing the product so obtained by the Exercise
Price as adjusted.

          (d) For the purpose of any computation under this Section 3.01, the
current market price per share of Common Stock at any date shall be deemed to
be the average of the daily closing price for 30 consecutive Business Days
commencing 45 Business Days before such date. The closing price for each day
shall be the last sale price regular way or, in case no such reported sales
takes place on such day, the average of the last reported bid and asked prices
regular way, in either case on the principal national securities exchange on
which the Common Stock is admitted to trading or listed, or if not listed or
admitted to trading on such exchange, the representative closing bid price as
reported by NASDAQ, or other similar organization if NASDAQ is no longer
reporting such information, or if not so available, the fair market price as
determined in good faith by the Board of Directors.

          (e) No adjustment in the Exercise Price shall be required unless such
adjustment would require an increase or decrease of at least twenty-five cents
($.25) in such price; provided, however, that any adjustments which by reason
of this paragraph (e) are not required to be made shall be carried forward and
taken into account in any subsequent adjustment. All calculations under this
Section 3.01 shall be made to the nearest cent or to the nearest one-hundredth
of a share, as the case may be. Notwithstanding anything in this Section 3.01
to the contrary, the Exercise Price shall not be reduced to less than the then
existing par value of the Common Stock as a result of any adjustment made
hereunder.

          (f) In the event that at any time, as a result of any adjustment made
pursuant to paragraph (a) of this Section 3.01, the Warrantholder thereafter
shall become entitled to receive any shares of the Company, other than Common
Stock, thereafter the number of such other shares so receivable upon exercise
of any Warrant shall be subject to adjustment from time to time


                                     - 5 -
<PAGE>

in a manner and on terms as nearly equivalent as practicable to the provisions
with respect to the Common Stock contained in paragraphs (a) to (e), inclusive,
of this Section 3.01.

     SECTION 3.02: NOTICE OF ADJUSTMENT. Whenever the number of Warrant Shares
or the Exercise Price is adjusted as herein provided, the Company shall prepare
and deliver to the Warrantholder a certificate signed by its President, any
Vice President, Treasurer or Secretary, setting forth the adjusted number of
shares purchasable upon the exercise of this Warrant and the Exercise Price of
such shares after such adjustment, setting forth a brief statement of the facts
requiring such adjustment and setting forth the computation by which adjustment
was made.

     SECTION 3.03: NO ADJUSTMENT FOR DIVIDENDS. No adjustment in respect of any
cash dividends shall be made during the term of this Warrant or upon the
exercise of this Warrant.

     SECTION 3.04: PRESERVATION OF PURCHASE RIGHTS IN CERTAIN TRANSACTIONS. In
case of any consolidation of the Company with or merger of the Company into
another corporation or in case of any sale or conveyance to another corporation
of the property of the Company as an entirety or substantially as an entirety,
the Company agrees that a condition of such transaction will be that the
Company or such successor or purchasing corporation, as the case may be, shall
execute with the Warrantholder an agreement granting the Warrantholder the
right thereafter, upon payment of the Exercise Price in effect immediately
prior to such action, to receive upon exercise of this Warrant the kind and
amount of shares and other securities and property which he would have owned or
have been entitled to receive after the happening of such consolidation,
merger, sale or conveyance had this Warrant been exercised immediately prior to
such action. Such agreement shall provide for adjustments, which shall be as
nearly equivalent as may be practicable to the adjustments provided for in this
Article III. The provisions of this Section 3.04 shall similarly apply to
successive consolidations, mergers, sales, or conveyances.

     SECTION 3.05: FORM OF WARRANT AFTER ADJUSTMENTS. The form of this Warrant
need not be changed because of any adjustments in the Exercise Price or the
number or kind of the Warrant Shares, and Warrants theretofore or thereafter
issued may continue to express the same price and number and kind of shares as
are stated in this Warrant as initially issued.

                                  ARTICLE  IV

                           Other Provisions Relating

                          TO RIGHTS OF WARRANTHOLDER

     SECTION 4.01: NO RIGHTS AS SHAREHOLDERS; NOTICE TO WARRANTHOLDERS. Nothing
contained in this Warrant shall be construed as conferring upon the
Warrantholder or his transferees the right to vote or to receive dividends or
to consent or to receive notice as shareholders in respect of any meeting of
shareholders for the election of directors of the Company or any other matter,
or any rights whatsoever as shareholders of the Company. If, however, at any
time prior to the expiration or exercise in full of the Warrants, any of the
following events shall occur:

          (a) the Company shall declare any dividend payable in any securities
upon its shares of Common Stock or make any distribution (other than a cash
dividend) to the holders of its shares of Common Stock; or


                                     - 6 -
<PAGE>

          (b) the Company shall offer to the holders of its shares of Common
Stock any additional shares of Common Stock or Common Stock Equivalents or any
right to subscribe thereto; or

          (c) a dissolution, liquidation or winding up of the Company (other
than in connection with a consolidation, merger, or sale of all or
substantially all of its property, assets, and business as an entirety) shall
be proposed;

          then, in any one or more of said events, the Company shall give
notice of such event to the Warrantholder. Such giving of notice shall be
initiated (i) at least 25 days prior to the date fixed as a record date or the
date of closing the Company's Stock transfer books for the determination of the
shareholders entitled to such dividend, distribution, or subscription rights,
or for the determination of the shareholders entitled to vote on such proposed
dissolution, liquidation or winding up. Such notice shall specify such record
date or the date of closing the stock transfer books, as the case may be.
Failure to provide such notice shall not affect the validity of any action
taken in connection with such dividend, distribution or subscription rights, or
proposed dissolution, liquidation or winding up.

     SECTION 4.02: LOST, STOLEN, MUTILATED OR DESTROYED WARRANTS. If this
warrant certificate is lost, stolen, mutilated or destroyed, the Company may,
on such terms as to indemnity or otherwise as it may in its discretion impose
(which shall, in the case of a mutilated Warrant, include the surrender
thereof), issue a new warrant certificate of like denomination and tenor as,
and in substitution for this Warrant.

     SECTION 4.03: RESERVATION OF SHARES. (a) The Company covenants and agrees
that at all times it shall reserve and keep available for the exercise of this
Warrant such number of authorized shares of Common Stock as are sufficient to
permit the exercise in full of this Warrant.

          (b) The Company covenants that all shares of Common Stock issued on
exercise of this Warrant will be validly issued, fully paid, nonassessable and
free of pre-emptive rights.

     SECTION 4.04: NO FRACTIONAL SHARES. Anything contained herein to the
contrary notwithstanding, the Company shall not be required to issue any
fraction of a share in connection with the exercise of this Warrant, and in any
case where the Warrantholder would, except for the provisions of this Section
4.04, be entitled under the terms of this Warrant to receive a fraction of a
share upon the exercise of this Warrant, the Company shall, upon the exercise
of this Warrant and receipt of the Exercise Price, issue the number of whole
shares purchasable upon exercise of this Warrant. The Company shall be required
to make any cash or other adjustment in respect of such fraction of a share to
which the Warrantholder would otherwise be entitled.

                                   ARTICLE V

                          TREATMENT OF WARRANTHOLDER

     SECTION 5.01. Prior to due presentment for registration of transfer of
this Warrant, the Company may deem and treat the Warrantholder as the absolute
owner of this Warrant (notwithstanding any notation of ownership or other
writing hereon) for the purpose of any



                                     - 7 -
<PAGE>



exercise hereof and for all other purposes and the Company shall not be
affected by any notice to the contrary.

                                  ARTICLE VI

                             TRANSFER RESTRICTIONS

in whole or in part, subject to the following restrictions.  Neither this
Warrant nor the Registrable Securities received upon exercise of this Warrant
shall be transferable unless registered under the Securities Act or unless an
exemption from registration is available.  Unless and until this Warrant or the
Registrable Securities are so registered, such securities and any certificate
thereof shall contain a legend on the face thereof, in form and substance
satisfactory to counsel for the Company, stating that the Warrant or
Registrable Securities, as the case may be, may not be sold, transferred or
otherwise disposed of unless, in the opinion of counsel satisfactory to the
Company, which may be counsel to the Company, the Warrant, or Registrable
Securities may be transferred without such registration.  This Warrant and the
Registrable Securities may also be subject to restrictions on transferability
under applicable state securities or blue sky laws.  Unless and until this
Warrant or Registrable Securities, as the case may be, are registered under the
Securities Act, the holder of such securities shall, if requested by the
Company, provide to the Company an opinion of counsel reasonably satisfactory
to the Company, to the effect that (i) the Warrant or Registrable Securities,
as the case may be, may be transferred without such registration and (ii) the
transfer will not violate any applicable state securities or blue sky laws. Any
transfer of this Warrant permitted hereunder shall be made by surrender of this
Warrant to the Company with the form of assignment annexed hereto properly
completed and duly executed and accompanied by (x) any necessary documentation
required hereunder and (y) funds sufficient to pay any transfer taxes
applicable.  Upon satisfaction of all transfer conditions, the Company, without
charge, shall execute and deliver a new Warrant in the name of the transferee
named in such transfer form, and this Warrant promptly shall be canceled.

     SECTION 6.02: SPLIT-UP, COMBINATION, EXCHANGE AND TRANSFER OF WARRANTS.
Subject to and limited by the provisions of Section 6.01 hereof, this Warrant
may be split up, combined or exchanged for another Warrant or Warrants
containing the same terms to purchase a like aggregate number of shares of
Common Stock. If the Warrantholder desires to split up, combine or exchange
this Warrant, he shall make such request in writing delivered to the Company
and shall surrender to the Company this Warrant and any other Warrants to be so
split up, combined or exchanged. Upon any such surrender for a split-up,
combination, or exchange, the Company shall execute and deliver to the Person
entitled thereto a Warrant or Warrants, as the case may be, as so requested.
The Company shall not be required to effect any split-up, combination or
exchange which will result in the issuance of a Warrant entitling the
Warrantholder to purchase upon exercise a fraction of a share of Common Stock
or a fractional Warrant. The Company may require such Warrantholder to pay a
sum sufficient to cover any tax or governmental charge that may be imposed in
connection with any split-up, combination or exchange of Warrants.

                                  ARTICLE VII

                 REGISTRATION UNDER THE SECURITIES ACT OF 1933

     SECTION 7.01: PIGGYBACK REGISTRATION. (a) RIGHT TO INCLUDE REGISTRABLE
SECURITIES. If at any time after June 30, 1996, the Company proposes to
register any class of debt or equity security or any Common Stock Equivalent
under the Securities Act on any form for the general registration of securities
under such Securities Act, whether or not for its own account (other than a
registration form relating to (i) a registration of a stock option, stock
purchase or compensation or incentive plan or stock issued or issuable pursuant
to any such plan, or a dividend investment plan; (ii) a registration of stock
proposed to be issued in exchange for securities or assets of, or in connection
with a merger or consolidation with, another corporation; or (iii) a
registration of stock proposed to be issued in exchange for other securities of
the Company) in a manner which would permit registration of Registrable
Securities for sale to the public under the Securities Act (a "Piggyback
Registration"), it will at such time give prompt written notice to all Holders
of Registrable Securities of its intention to do so and of such Holders' rights
under this Section 7.01. Upon the written request of any such Holder made
within 15 days after the receipt of any such notice (which request shall
specify the Registrable Securities intended to be disposed of by such Holder
and the intended method of disposition thereof), the Company will include in
the Registration Statement the Registrable Securities which the Company has
been so requested to register by the Holders thereof.

          (b) WITHDRAWAL OF PIGGYBACK REGISTRATION BY COMPANY. If, at any time
after giving written notice of its intention to register any securities but
prior to the effective date of the Registration Statement filed in connection
with such registration, the Company shall determine for any reason not to
register such securities, the Company may, at its election, give written notice
of such determination to each Holder and, thereupon shall be relieved of its
obligation to register any Registrable Securities in connection with such
registration. All best efforts obligations of the Company pursuant to Section
7.04 shall cease if the Company determines to terminate any registration where
Registrable Securities are being registered pursuant to this Section 7.01.

          (c) PIGGYBACK REGISTRATION OF UNDERWRITTEN PUBLIC OFFERINGS. If a
Piggyback Registration requested pursuant to this Section 7.01 involves an un-
derwritten offering, then, (i) all Holders requesting to be included in the
Company's registration must sell their Registrable Securities to the
underwriters selected by the Company on the same terms and conditions as apply
to other selling shareholders or the Company, if there are no selling
shareholders; and (ii) any Holder requesting to be included in such
registration may elect in writing, not later than five (5) Business Days prior
to the effectiveness of the Registration Statement filed in connection with
such registration, not to register such securities in connection with such
registration.

          (d) PAYMENT OF REGISTRATION EXPENSES FOR REGISTRATION. The Company
will pay all Registration Expenses in connection with each registration of
Registrable Securities requested pursuant to this Section 7.01, except for the
fees and disbursements of any counsel retained by the Holders of the
Registrable Securities being registered and such Holders' pro rata share of any
filing fees or other expenses directly and solely resulting from the inclusion
of the Registrable Securities in the Registration Statement, including
underwriting discounts and commissions.

<PAGE>


          (e) PRIORITY IN PIGGYBACK REGISTRATION. If a registration pursuant to
this Section 7.01 involves an underwritten offering and the managing
underwriter advises the Company in writing that, in its opinion, the number or
kind of Registrable Securities requested to be included in such registration
would have a material adverse effect on such offering, including an adverse
decrease in the price at which such securities can be sold, then the amount or
kind of Registrable Securities to be offered for the accounts of Holders shall
be eliminated entirely or reduced pro rata as to all requesting Holders on the
basis of the relative number of Registrable Securities each such Holder has
requested to be included in such registration, to the extent necessary to
reduce the total amount or kind of securities to be included in such offering
to the amount recommended by such managing underwriter; provided, however, that
no securities may be offered in such registration for the account of persons
other than the Company by virtue of their also having "piggyback" registration
rights, or otherwise, unless the Registrable Securities requested to be
included in such registration are so included on a pro rata basis.

          (f) EXPIRATION OF PIGGYBACK REGISTRATION IN RIGHTS. The Piggyback
Registration rights granted to the Holders of Registrable Securities by this
Section 7.01 shall survive the exercise of the Warrant or the transactions or
events pursuant to which such Registrable Securities were issued, but all such
rights will terminate in all events three (3) years after exercise of this
Warrant.

     SECTION 7.02: DEMAND REGISTRATION. (a) REQUEST FOR REGISTRATION. Anytime
after June 30, 1996, subject to the limitations set forth below in this Section
7.02, any Warrantholder or Holders who hold in the aggregate 50% or more of the
Registrable Securities (assuming, for such calculation, that all Warrantholders
have previously exercised their Warrants) may make a written request for the
registration under the Securities Act on Form S-3 or such other form of
registration statement permitting incorporation by reference of reports filed
under the Exchange Act, of all of their Registrable Securities (the "Demand
Registration"), and the Company shall use its best efforts to effect such
Demand Registration. The Warrantholders and Holders, as a group, shall be
limited to one Demand Registration.  All rights to the Demand Registration
shall terminate three (3) years after the exercise of this Warrant.

          (b) LIMITATIONS ON DEMAND REGISTRATION. The Company shall not be
required to effect the Demand Registration for a 12 month period following the
effective date of a Registration Statement pertaining to an underwritten Public
Offering for the account of the Company. Upon receipt of a request for the
Demand Registration, the Company may postpone the filing of a Registration
Statement for the Demand Registration for a period not to exceed 6 months, if
the Company furnishes to the Warrantholders and Holders requesting registration
a certificate signed by the Company's President stating that in the good faith
judgment of the Board of Directors it would be seriously detrimental to the
Company for a Public Offering to be commenced in the near future. If the
Company so determines to postpone the Demand Registration, it shall promptly
notify the requesting Warrantholders and Holders of such determination
including the reason therefor, whereupon the requesting Warrantholders and
Holders shall be entitled to withdraw such request and, if following the
withdrawal of such requests, Warrantholders and Holders of fewer than 50% of
the Registrable Securities are still requesting the Demand Registration, such
Demand Registration shall not count as the Demand Registration, whether or not
the Company proceeds with such registration, but the Company shall be under no
obligation to proceed with such registration as the Demand Registration.

                                    - 10 -
<PAGE>

          (c) PAYMENT OF REGISTRATION EXPENSES FOR DEMAND REGISTRATION. The
Company will pay all Registration Expenses in connection with the Demand
Registration, except for the fees and disbursements of any counsel retained by
the Warrantholders and Holders of the Registrable Securities being registered
and any filing fees or other expenses directly and solely resulting from the
inclusion of the Registrable Securities in the Registration Statement including
underwriting discounts and commissions.

          (d) PROCEDURE FOR REQUESTING DEMAND REGISTRATION. A request for the
Demand Registration shall specify the aggregate number of the Registrable
Securities proposed to be sold and shall also specify the intended method of
disposition thereof.  Within ten (10) days after receipt of such a request the
Company will give written notice of such registration request to all
Warrantholders and Holders, and the Company will include in such registration
all Registrable Securities with respect to which the Company has received
written requests for inclusion therein within 20 Business Days after the date
on which such notice is given. Each such request shall also specify the
aggregate number of Registrable Securities to be registered and the intended
method of disposition thereof.

          (e) SELECTION OF UNDERWRITERS. If the Demand Registration is
requested to be in the form of an underwritten offering, the managing
underwriter shall be selected by the Company and the co-manager (if any) and
the independent price required under the rules of the NASD (if any) shall be
selected and obtained by the Warrantholders and Holders of a majority in
aggregate amount of the Registrable Securities to be registered subject to the
Company's consent, which consent shall not be unreasonably withheld.

     SECTION 7.03: BUY-OUTS OF REGISTRATION DEMAND. In lieu of carrying out its
obligations to effect the Piggyback Registration or the Demand Registration of
Registrable Securities pursuant to this Article VII, the Company may discharge
such obligation by offering to purchase and, if accepted, by purchasing such
Registrable Securities requested to be registered at 95% of the closing bid or
sale price of the Common Stock on the day the request or demand for
Registration is made.  If the offer to purchase is accepted by the Holder,
payment will be made by wire transfer or certified check in U.S. dollars within
ten (10) business days of receipt by the Company of written acceptance by such
Holder, accompanied by the stock certificate representing such shares duly
endorsed to the Company.

     SECTION 7.04: REGISTRATION PROCEDURES.  If and whenever the Company is
required pursuant to this Article VII to use its best efforts to effect the
registration of the Registrable Securities under the Securities Act, the
Company will, as expeditiously as possible:

          (a)  prepare and file with the SEC a Registration Statement which
includes the Registrable Securities and use its best efforts to cause such
Registration Statement to become and remain effective until the distribution
described in the registration statement has been completed or until the
participating Holders can sell all such Registrable Securities pursuant to Rule
144;

          (b) prepare and file with the SEC such amendments and supplements to
such Registration Statement and the Prospectus used in connection therewith as
may be necessary to keep such Registration Statement effective and to comply
with the provisions of the Securities Act with respect to the sale or other
disposition of Registrable Securities covered by such

                                    - 11 -
<PAGE>

Registration Statement whenever a Holder shall desire to sell or otherwise
dispose of the same, but only to the extent provided in this Article VII;

          (c)  furnish to each participating Holder (and to each underwriter,
if any, of Registrable Securities) such number of copies of a Prospectus,
including a preliminary Prospectus, in conformity with the requirements of the
Securities Act, and such other documents, as such Holder may reasonably request
in order to facilitate the public sale or other disposition of the Registrable
Securities;

          (d)  use its best efforts to register or qualify the Registrable
Securities covered by such registration statement under such state securities
or blue sky laws of such jurisdiction as each participating Holder shall
reasonably request and do any and all other acts and things which may be
necessary under such securities or blue sky laws to enable such Holder to
consummate the public sale or other disposition in such jurisdictions of the
Registrable Securities, except that the Company shall not for any purpose be
required to consent generally to service of process or qualify to do business
as a foreign corporation in any jurisdiction wherein it is not so qualified;

          (e)  before filing the Registration Statement or Prospectus or
amendments or supplements thereto, furnish to counsel selected by the
participating Holders copies of such documents proposed to be filed which shall
be subject to the reasonable approval of such counsel;

          (f)  enter into and perform its obligations under an underwriting
agreement, in usual and customary form, with the managing underwriter of such
offer;

          (g)  notify the participating Holders at any time when a Prospectus
relating to any Registrable Securities covered by such Registration Statement
is required to be delivered under the Securities Act, of the happening of any
event as a result of which the Prospectus included in such Registration
Statement, as then in effect, includes an untrue statement of a material fact
or omits to state a material fact required to be stated therein or necessary to
make the statements therein not misleading in light of the circumstances then
existing and promptly file such amendments and supplements as may be necessary
so that, as thereafter delivered to such Holders, such Prospectus shall not
include an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading in light of the circumstances then existing and use its best efforts
to cause each such amendment and supplement to become effective;

          (h)  furnish at the request of the participating Holders on the date
that such Registrable Securities are delivered to the underwriters for sale in
connection with a registration pursuant to this Article VII an opinion, dated
such date, of the counsel representing the Company, for purposes of such
registration, in form and substance as is customarily given by company counsel
to the underwriters in an underwritten public offer addressed to the
underwriters, if any, and to such Holders, and (ii) a letter dated such date,
from the independent certified public accountants of the Company, in form and
substance as is customarily given by independent certified public accountants
to underwriters in an underwritten public offer, addressed to the underwriters
and to such Holders; and


                                    - 12 -
<PAGE>

          (i)  use its best efforts to cause all such Registrable Securities to
be listed on the securities exchange or the Nasdaq National Market, if any, on
which the Company's Common Stock is then listed.

          The Company may require each seller of Registrable Securities as to
which any registration is being effected to furnish to the Company such
information regarding the distribution of such securities and such other
information as may otherwise be required to be included in such Registration
Statement, as the Company may from time to time reasonably request in writing.

          Each Holder of Registrable Securities agrees by acquisition of such
Registrable Securities that, upon receipt of any notice from the Company of the
happening of any event of the kind described in paragraph (g) hereof, such
Holder will forthwith discontinue disposition of such Registrable Securities
covered by such Registration Statement or Prospectus until such Holder's
receipt of the copies of the supplemented or amended Prospectus, or until it is
advised in writing by the Company that the use of the applicable Prospectus may
be resumed, and has received copies of any additional or supplemental filings
which are incorporated by reference in such Prospectus, and, if so directed by
the Company, such Holder will deliver to the Company (at the Company's expense)
all copies, other than permanent file copies then in such Holder's possession,
of the Prospectus covering such Registrable Securities current at the time of
receipt of such notice.

     SECTION 7.05:  INDEMNIFICATION.  In the event Registrable Securities are
registered pursuant to this Article VII:

          (a)  To the extent permitted by law, the Company will indemnify and
hold harmless each Holder of Registrable Securities which are included in a
Registration Statement filed pursuant to the provisions of this Agreement and
any underwriter (within the meaning of the Securities Act) with respect to the
Registrable Securities, and each officer, director, employee and agent thereof
and each person, if any, who otherwise controls such Holder or underwriter
(within the meaning of the Securities Act), against any losses or claims,
damages, expenses or liabilities, joint or several, to which they may become
subject under the Securities Act, the Exchange Act or other federal or state
law, or otherwise, insofar as such losses, claims, damages, expenses or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue or allegedly untrue statement of any material fact contained in the
Registration Statement for the Registrable Securities, including any
preliminary Prospectus or final Prospectus contained therein or any amendments
or supplements thereto, or any document incident to the registration or
qualification of any Registrable Securities, or arise out of or are based upon
the omission or alleged omission to state therein a material fact required to
be stated therein or allegedly necessary to make the statements therein not
misleading or arise out of any violation or alleged violation by the Company of
the Securities Act, the Exchange Act, any state securities law or any rule or
regulation promulgated under the Securities Act, the Exchange Act or any state
securities law; and will reimburse such Holder, any underwriter, officer,
director, employee, agent or controlling person for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that the
indemnity agreement contained in this Section 7.05(a) shall not apply to
amounts paid in settlement of any such loss, claim, damage, expense, liability
or action if such settlement is

                                    - 13 -
<PAGE>

effected without the written consent of the Company, which shall not be
unreasonably withheld, nor shall the Company be liable under this Section
7.05(a) to such Holder, such underwriter, officer, director, employee, agent or
controlling person for any such loss, claim, damage, expense, liability or
action to the extent that it arises out of, or is based upon, an untrue
statement or allegedly untrue statement or omission or alleged omission made in
connection with such Registration Statement, preliminary Prospectus, final
Prospectus, or amendments or supplements thereto, in reliance upon and in
conformity with information furnished in writing expressly for use in
connection with such registration by such Holder, such underwriter, officer,
director, employee, agent or such controlling person.

          (b)  To the extent permitted by law, each Holder of Registrable
Securities which are included in a Registration Statement filed pursuant to the
provisions of this Agreement will indemnify and hold harmless the Company, each
of its employees, agents, directors and officers, each person, if any, who
controls the Company within the meaning of the Securities Act, and any
underwriter (within the meaning of the Securities Act) against any losses,
claims, damages, expenses or liabilities to which the Company or any such
person or underwriter may become subject, under the Securities Act, the
Exchange Act or other federal or state law or otherwise, insofar as such
losses, claims, damages, expenses or liabilities (or actions in respect
thereof) arise out of, or are based upon any untrue or allegedly untrue
statement of any material fact contained in a Registration Statement for the
Registrable Securities, including any preliminary Prospectus or final
Prospectus contained therein or any amendments or supplements thereto, or any
document incident to the registration or qualification of any Registrable
Securities, or arise out of or are based upon the omission or alleged omission
to state therein a material fact required to be stated therein or allegedly
necessary to make the statements therein not misleading; in each case to the
extent that such untrue statement or allegedly untrue statement or omission or
alleged omission was made in such Registration Statement, preliminary
Prospectus, final Prospectus or amendments or supplements thereto, in reliance
upon and in conformity with information furnished in writing by such Holder
expressly for use in connection with such registration; provided, however, that
the indemnity agreement contained in this Section 7.05(b) shall not apply to
amounts paid in settlement of any such loss, claim, damage, expense, liability
or action if such settlement is effected without the written consent of such
Holder, which shall not be unreasonably withheld; and such Holder will
reimburse the Company or any such person or underwriter for any legal or other
expenses reasonably incurred by the Company or any such person or underwriter
in connection with investigating or defending such loss, claim, damage,
liability, expense or action.

          (c)  Promptly after receipt by an indemnified party under this
Section 7.05 of notice of the commencement of any action, such indemnified
party will, if a claim in respect thereof is to be made against any
indemnifying party under this Section 7.05, notify the indemnifying party in
writing of the commencement thereof and generally summarize such action.  The
indemnifying party shall have the right to participate in and to assume the
defense thereof with counsel mutually satisfactory to the parties.  An
indemnifying party shall not have the right to direct the defense of such an
action on behalf of an indemnified party if such indemnified party has
reasonably concluded that there may be defenses available to it that are
different from or additional to those available to the indemnifying party;
provided, however, that in such event, the indemnifying party shall bear the
fees and expenses of only one (1) separate counsel for all indemnified parties,
such separate counsel to be reasonably satisfactory to the indemnifying party.
The failure to notify an indemnifying party promptly of the commencement of any
such action if

                                    - 14 -
<PAGE>

prejudicial to the ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
7.05, but the omission so to notify the indemnifying party will not relieve
such party of any liability that such party may have to any indemnified party
otherwise than under this Section.

          (d)  To the extent permitted by law, the indemnification provided for
under this Section 7.05 will remain in full force and effect regardless of any
investigation made by or on behalf of the indemnified party or any officer,
director or controlling person (within the meaning of the Securities Act) of
such indemnified party and will survive the transfer of securities.

          (e)  If for any reason the foregoing indemnity is unavailable to, or
is insufficient to hold harmless an indemnified party, then the indemnifying
party shall contribute to the amount paid or payable by the indemnified party
as a result of such losses, claims, damages, liabilities or expenses (i) in
such proportion as is appropriate to reflect the relative benefits received by
the indemnifying party on the one hand and the indemnified party on the other
or (ii) if the allocation provided by clause (i) above is not permitted by
applicable law, or provides a lesser sum to the indemnified party than the
amount hereinafter calculated, in such proportion as is appropriate to reflect
not only the relative benefits received by the indemnifying party on the one
hand and the indemnified party on the other but also the relative fault of the
indemnifying party and the indemnified party as well as any other relevant
equitable considerations.  Notwithstanding the foregoing, no underwriter, if
any, shall be required to contribute any amount in excess of the amount by
which the total price at which the securities underwritten by it and
distributed to the public were offered to the public exceeds the amount of any
damages which underwriter has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission.  No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation.  The obligation of any
underwriters to contribute pursuant to this Section 7.05(e) shall be several in
proportion to their respective underwriting commitments and not joint.

     SECTION 7.06: RESTRICTIONS ON PUBLIC SALE.  Each holder of Registrable
Securities whose Registrable Securities are covered by a Registration Statement
filed pursuant to Article VII hereof agrees, if requested by the managing
underwriters in an underwritten offering, not to effect any public sale or
distribution of any securities of the Company of the same class as the
securities included in such Registration Statement, including a sale pursuant
to Rule 144 under the Securities Act (except as part of such underwritten
registration), during the 10-day period prior to, and during the 90-day period
beginning on, the closing date of the underwritten offering made pursuant to
such Registration Statement, to the extent timely notified in writing by the
managing underwriters.

          The foregoing provision shall not apply to any Holder if such Holder
is prevented by applicable statute or regulation from entering into any such
agreement. However, any such Holder shall undertake, in its request to
participate in any such underwritten offering, not to effect any public sale or
distribution of the applicable Registrable Securities commencing on the date of
sale of such applicable class of Registrable Securities unless it has provided
45 days' prior written notice of such sale or distribution to the underwriter
or underwriters.

                                    - 15 -
<PAGE>


     SECTION 7.07: REPORTS UNDER THE EXCHANGE ACT.  With a view to making
available to the Holder the benefits of Rule 144 promulgated under the
Securities Act and any other rule or regulation of the SEC that may at any time
permit a Holder of Registrable Securities to sell such securities of the
Company to the public without registration, and with a view to making it
possible for any such holder to register the Registrable Securities pursuant to
a registration on Form S-3, the Company agrees, subject to this Article VII in
the case of Section 7.07(b), to:

          (a)  make available adequate current public information as
contemplated by Rule 144 (c)(1) or (2);

          (b)  take such action as is necessary to enable a Holder to utilize
Form S-3 for the sale of Registrable Securities;

          (c)  file with the SEC in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange
Act; and

          (d)  furnish to a Holder owning any Registrable Securities upon
request (i) a written statement by the Company that it has complied with the
reporting requirements of Rule 144, the Securities Act and the Exchange Act, or
that it qualifies as a registrant whose Registrable Securities may be resold
pursuant to Form S-3 (at any time after it so qualifies), (ii) a copy of the
most recent annual or quarterly report of the Company and such other reports
and documents so filed by the Company, and (iii) such other information as may
be reasonably required in availing any Holder of Registrable Securities of any
rule or regulation of the SEC which permits the selling of any such Registrable
Securities without registration or pursuant to such form.

                                 ARTICLE VIII

                                 OTHER MATTERS

     SECTION 8.01: EXPENSES OF TRANSFER. The Company will from time to time
promptly pay, subject to the provisions of Section 6.01, 6.02 and paragraph (d)
of Section 2.02, all taxes and charges that may be imposed upon the Company in
respect to the issuance or delivery of Warrant Shares upon the exercise of this
Warrant by the Warrantholder.

     SECTION 8.02: SUCCESSORS AND ASSIGNS. All the covenants and provisions of
this Warrant by or for the benefit of any party hereto shall bind and inure to
the benefit of its permitted successors and assigns hereunder.

     SECTION 8.03: AMENDMENTS AND WAIVERS. The provisions of this Warrant,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waiver or consents to departures from the provisions hereof
may not be given unless the Company has obtained the written consent of holders
of at least a majority of the outstanding Warrants or Registrable Securities
(assuming, for purposes of calculating such consent, that all Warrantholders
have exercised the Warrants at the time such consent is sought). Warrantholders
and Holders shall be bound by any consent authorized by this Section whether or
not certificates representing such Warrants or Registrable Securities have been
marked to indicate such consent.

     SECTION 8.04: GOVERNING LAW. This Warrant shall be governed by and
construed in accordance with the laws of the State of New York.

     SECTION 8.05: SEVERABILITY. In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstances,
is held invalid, illegal or unenforceable, the validity, legality and
enforceability of any such provisions in every other respect and of the
remaining provisions contained herein shall not be affected or impaired
thereby.

     SECTION 8.06: INTEGRATION/ENTIRE AGREEMENT. This Warrant is intended to be
a complete and exclusive statement of the agreement and understanding of the
parties hereto in respect of the subject matter contained herein. There are no

               (b)  SHORT TERM FORECASTS.  At the time that HMRI first
reasonably expects that it will require Material for Clinical Work or commercial
sale within the ensuing 12 month period, and thereafter, at least 30 days prior
to the first day of each succeeding calendar quarter, HMRI shall furnish
Alliance with a rolling forecast of the quantities of Material that HMRI intends
to order by month, for the first six months, and by quarter, for the last six


                                        4
<PAGE>

months, during the 12 month period commencing with that calendar quarter.  Such
forecasts shall constitute binding commitments of HMRI to purchase the
percentages of Material set forth below.  An example of form for the short-term
forecast is set out in Exhibit 1 (forecasts 1 and 2).  The binding commitment of
HMRI to purchase the forecasted quantities for the first three months of the
forecast shall be further evidenced by purchase orders to be issued to Alliance
in accordance with Section 2.3.  HMRI shall be required to purchase that
percentage of the quantity of Material specified in the forecast for successive
quarters as follows:

                                           Percentage of Material
              Period                     indicated in Forecast that
          of the Forecast               HMRI is Required to Purchase
         -----------------              ----------------------------

          2.3  ORDERS.  HMRI shall place each purchase order with Alliance for
Material to be delivered hereunder at least 90 days prior to the delivery date
specified in each respective order.  Such orders shall be in full lots and shall
specify for each three month period an aggregate quantity of Material which is
at least as great as the amount of Material required to be purchased by HMRI
pursuant to Section 2.2.  Alliance shall confirm in writing each such purchase
order within ten business days of receipt thereof.  Alliance shall deliver
against each such order in accordance with Section 2.4.  HMRI shall be obligated
to purchase all such Material ordered and delivered by the delivery date
specified in HMRI's purchase order, provided that such Material meet the
Specifications.  Alliance shall use reasonable efforts to meet any order for a
quantity of Material in excess of the amounts forecasted under Section 2.2(b)
for such period.  Any purchase orders, purchase order releases, confirmations,
acceptances, advices and similar documents submitted by either party in
conducting the activities contemplated under this Agreement are for
administration purposes only and shall not add to or modify the terms of the
Agreement.  To the extent of any conflict or inconsistency between this
Agreement and any such document, the terms and conditions of this Agreement
shall control as to a particular order unless otherwise agreed to in writing by
the parties.

          2.4  DELIVERY.  Delivery terms shall be F.O.B. the Otisville Facility
or such other facility mutually agreed to by the parties.  Alliance shall ship
Material on a carrier or carriers specified by HMRI in accordance with HMRI's
purchase order form or as otherwise directed by HMRI in writing.  Title to any
Material purchased by HMRI shall pass to HMRI upon the earlier of (i) a common
carrier accepting possession or control of such Material or (ii) the passage of
such Material from the loading dock of Alliance's facility to HMRI or any
employee, agent or contractor thereof.

          2.5  REJECTED GOODS/SHORTAGES.

               (a) HMRI shall notify Alliance in writing of any claim relating
to Material that fail to meet the Specifications, arising from defective
manufacture, storage or handling of such Material by Alliance prior to shipment
or any shortage in quantity of any shipment of Material within 45 days of
receipt of such Material.  In the event of such rejection or shortage, Alliance
shall replace the rejected Material or make up the shortage within ten business
days if replacement stock is available, and in any case as soon as reasonably
possible after receiving such notice, at no additional cost to HMRI, and
Alliance shall make arrangements with HMRI for the return of any rejected
Material, such return shipping charges to be paid by Alliance for Material
determined after inspection and testing by Alliance to fail to meet the
Specifications.  In the event that only a limited supply of Material is
available at the time of such rejection or shortage, then Alliance shall ship to
HMRI such quantities of Material as are available and HMRI will be promptly
reimbursed or credited against future orders, at HMRI's option, for amounts paid
for the remaining quantity of rejected Material.

               (b)  In the event of a disagreement regarding the Material which
fail to meet the Specifications which HMRI and Alliance are unable to resolve, a
sample of such Material shall be submitted by Alliance to an independent
laboratory reasonably acceptable to both parties for testing against the
Specifications and the test results obtained by such laboratory shall be final
and controlling.  The fees and expenses of such laboratory testing shall be
borne entirely by the party against whom such laboratory's findings are made.
In the event the test results indicate that the Material in question do not
conform to the Specifications, Alliance shall replace such Material at no
additional cost to HMRI within seven business days after receipt of such results
if replacement stock is available, and in any case as soon as reasonably
possible after receipt of such results.  In the event the test results indicate
that the Material in question does conform to the Specifications, HMRI shall pay
all additional shipping and transportation costs incurred as a result of the
disagreement.

          2.6  BACK-UP INVENTORY.  Subject to terms of this Agreement, Alliance
shall maintain an adequate back-up inventory of Material to meet HMRI's purchase
orders, to replace rejected Material and other similar situations.  Such
inventory level shall be mutually agreed upon by the parties.  Alliance will
notify HMRI promptly if such back-up inventory falls below such agreed upon
level and include the reason for the lower level.  The parties will discuss and
agree upon a course of action to solve the problem, provided however, that such
agreement shall act in no way as a waiver of HMRI's rights or remedies herein if
Alliance fails to deliver Material under the provisions of this Agreement.

          2.7  FAILURE TO SUPPLY; CAPACITY ALLOCATION.

               (a) In the event that Alliance, upon receiving a forecast under
Section 2.2 or a firm order under Section 2.3, is, or anticipates that it will
be, unable to meet such forecast or firm order, either in whole or in part, and
whether due to circumstances arising under Section 11.3 or otherwise, Alliance
shall give written notice of such inability to HMRI within ten days of receipt
of such forecast or firm order.  If such inability is partial, Alliance shall
deliver against firm orders such quantities of Material as are available.

               (b)  Alliance and HMRI shall meet within 15 days of such written
notice to consider and, if appropriate, pursue alternative arrangements for
meeting HMRI's requirements for Material.  Such arrangements may include
transferring equipment and/or technology necessary for the production of
Material to an alternative site or to a Third Party, manufacturing Material at
HMRI's own facilities, or, if HMRI is already manufacturing quantities of
Material, increasing HMRI's production of Material, PROVIDED that any such
alternative pursued shall be subject to all required regulatory approvals.  Any
alternative arrangements entered into pursuant to this Section 2.7 shall act in
no way as a waiver of any other rights or remedies which HMRI may have under
this Agreement or otherwise.

               (c) In the event that Alliance's inability to meet firm orders or
forecasts is due to a shortage of production capacity at Alliance's facilities,
in addition to the requirements on Section 2.7(a) and Section 2.7(b) above,
Alliance shall promptly notify HMRI of such shortage of production capacity,
and, if possible, the date such shortage of production capacity is expected to
end.  In such event, Alliance shall allocate its available production capacity
to the production of Material in such proportion as the production capacity
actually utilized to meet orders for Material over the previous 12 month period
bears to Alliance's total production capacity over that same period.

               (d)  Alliance shall notify HMRI as soon as possible of the date
upon which such shortage of production capacity will cease.  Within 30 days of
such notification, HMRI shall resume obtaining its requirements for Material in
such proportions as HMRI ordered from Alliance prior to the shortage of
production to the extent such resumption is consistent with the contractual
arrangements entered into as provided in Section 2.7(b).

          2.11 AUDITS.  HMRI shall have the right to nominate an independent
certified public accountant reasonably acceptable to and approved by Alliance or
HMRI's own internal accountant who shall have access, during regular business
hours and upon reasonable notice, to audit those records and supporting
documentation of Alliance, to the extent necessary to verify the Manufacturing
Costs, but this right may not be exercised more than once in any calendar year,
and once a calendar year is audited it may not be reaudited, and said accountant
shall disclose to HMRI only information relating solely to the accuracy and
nature of the Manufacturing Costs and the payments made according to this
Agreement.  Alliance shall maintain such records and supporting documentation
for a period of three years from the date HMRI receives the invoice which is
based upon such records and supporting documentation.  If, pursuant to such
review, such accountant determines the actual Manufacturing Costs for a


                                        9

particular year are less than the Standard Manufacturing Costs, then in addition
to paying the amounts as set forth in Section 2.10(d) above, Alliance shall pay
the costs of such investigation.  For any refund owed by Alliance to HMRI under
this Section 2.11 greater than two percent, Alliance shall pay, in addition to
the amount due, interest on such amount from the time the amount was due at the
then current prime rate as quoted in the Eastern edition of THE WALL STREET
JOURNAL.

          2.12 TEMPORARY IDLING.  **




          2.13 PACKAGING INFORMATION.  All packaging and labelling information

regulatory approvals, and provided to Alliance a sufficient period of time in
advance of any requirements that Material be delivered in packaged form to
enable Alliance to supply the necessary materials and meet such delivery
requirements.

          2.14 SUPPLY OF MATERIAL TO AFFILIATES.  HMRI shall have the right to
designate any of its Affiliates who are sublicensees under the License Agreement
in any country of the Territory as a direct purchaser (a "Direct Purchaser") of
Material under this Agreement.  Alliance shall manufacture, sell and deliver,
and such Direct Purchaser shall purchase, Material for the same price and with
such other rights, obligations and conditions under this Agreement to which HMRI
is entitled, or by which HMRI is bound, as HMRI deems necessary or appropriate
to enable such Direct Purchaser to perform Clinical Work and to market, sell and
distribute Material, PROVIDED, that HMRI shall remain responsible to Alliance
for all obligations of HMRI and such Direct Purchasers.

          2.15 EXPORTS.  The parties acknowledge that the export of technical
data, materials, or products is subject to the exporting party receiving any
necessary export licenses and that the parties cannot be responsible for any
delays attributable to export controls which are beyond the reasonable control
of the exporting party.  Alliance and HMRI agree not to export or re-export,
directly or indirectly, any information, technical data, the direct product of
such data, samples, or equipment received or generated under this Agreement in
violation of any statutes or governmental regulations which may be applicable,
including, but not limited to, the Export Administration Act of 1979, as
amended, its rules and regulations, including, but not limited to, Part 779 of
the United States Export Control Regulations, published by the United States
Department of Commerce, and other applicable export laws.  Alliance and HMRI
agree to use reasonable best efforts to obtain similar covenants from their
licensees, sublicensees, and contractors with respect to the subject matter of
this Section.

          2.16 TAXES.  Subject to the provisions of this Section 2.13, HMRI or
its Affiliates, as the case may be, shall reimburse Alliance for all tariffs,
duties and excise, sales or use, value added or other taxes or levies
(collectively, "Taxes") that may be paid by Alliance with respect to the
manufacture and sale to HMRI or its Affiliates, as the case may be, of Material.
Notwithstanding the foregoing, HMRI shall have no reimbursement obligations
under this Section 2.13 to the extent that (i) such Taxes are based on
Alliance's net income or (ii) such Taxes are recoverable or offset by Alliance,
in whole or in part, as a credit, rebate, deduction or otherwise.

          3.2  EARLY TERMINATION.

               (a)  This Agreement shall terminate upon the early termination of
the License Agreement pursuant to Section 13.1 or 13.3 of the License Agreement
or Section 13.2 of the License Agreement upon the failure of HMRI to cure a
default thereunder.

               (b)  This Agreement may be terminated by either party upon 90
days written notice to the other party if any provision hereof is materially
breached, unless such breach is corrected or reasonable efforts are being made
to correct such breach within the 90-day notice period.

          3.3  CONSEQUENCES OF TERMINATION & SURVIVAL.  Termination of this
Agreement shall not relieve either party of its obligations incurred prior to
termination.  The obligations under Articles 5, Complaints and Product Recalls;
6, Warranties; 7, Nondisclosure and Confidentiality; and 8, Indemnification and
Insurance, shall survive expiration or termination of this Agreement or of any
extensions thereof.

                                   ARTICLE IV
                             CERTIFICATES AND ACCESS

          4.1  CERTIFICATES OF ANALYSIS.  Alliance shall perform, or cause to be
performed, sample tests on each lot of Material purchased pursuant to this
Agreement before delivery to HMRI.  Each test report shall set forth the items
tested, specifications and test results in a certificate of analysis, containing
the types of information which shall have been approved by mutual agreement of
the parties, for each lot delivered.  Alliance shall send, or cause to be sent,
such certificates to HMRI prior to delivery of each lot.

          4.2  CERTIFICATE OF MANUFACTURING COMPLIANCE.  Alliance shall provide,
or cause to be provided, for Material purchased a certificate of manufacturing
compliance, containing the types of information which shall have been approved
by mutual agreement of the parties, which will certify that the lots of Material
are manufactured in accordance with the Specifications, CGMP and in compliance
with the regulatory requirements described in the IND or NDA, as applicable.
Alliance shall advise HMRI before release of a lot of Material of any deviation
in the manufacture of such Material.  In case of failure to meet Specifications
in the manufacture of a lot of Material, Alliance shall inform HMRI of the
rejected lot, and shall provide a written summary of the investigation of the
causes by Alliance's quality organization.  Alliance shall advise HMRI
immediately if an authorized agent of the FDA or other governmental regulatory
agency visits any of Alliance's manufacturing facilities concerning Material.
Alliance shall furnish to HMRI the report by such agency of such visit, to the
extent that such report relates to Material, and the application of such report
to Material delivered to HMRI, if any, within ten business days of Alliance's
receipt of such report.  The parties agree to review and cooperate fully on any
written response to the FDA or other governmental regulatory agency regarding
these matters.

          4.3  SUPPLIER CERTIFICATION.  Alliance shall make all reasonable
efforts, with HMRI's assistance, and to the extent possible under regulatory
requirements, to become certified under HMRI's Certification Program.

          4.4  ACCESS TO FACILITIES.  HMRI shall have the right to inspect and
visit from time to time upon at least 24 hours prior notice and during normal
business hours those portions of the manufacturing facilities of Alliance where
Material is being manufactured, stored or tested, to ascertain compliance with

<PAGE>

proposes to change the process for manufacturing Material or any other change
and HMRI agrees to such change.  If the FDA or other applicable governmental
regulatory agency asserts any notice to the effect that Alliance has failed to
comply with any law or regulation in connection with the manufacture, storage or
handling of Material, or if Alliance delivers nonconforming Material, then HMRI
shall have the right to inspect such portions of the manufacturing facilities of
Alliance that relate to the manufacture of Material upon reasonable notice and
during normal business hours as often as is reasonably necessary to ascertain
that Alliance is correcting such failure in an expedient manner.

                                    ARTICLE V
                         COMPLAINTS AND MATERIAL RECALLS

          5.1  COMPLAINTS.  In the event that either Alliance or HMRI shall
receive any communications from third parties alleging adverse reactions due to
use of Material or other complaints involving Material, the parties shall
cooperate in addressing such complaints and shall take all appropriate
corrective actions.

          5.2  MATERIAL RECALLS.  In the event (a) any government authority
issues a request, directive or order that any Material be recalled, or (b) a
court of competent jurisdiction orders such a recall, or (c) Alliance or HMRI
shall reasonably determine that Material should be recalled, the parties shall
take all appropriate corrective actions, and shall cooperate in the
investigations surrounding the recall.  In the event that such recall results
from any cause or event arising from defective manufacture, storage or handling
of such Material by Alliance, Alliance shall be responsible for all expenses of
the recall, and shall promptly replace such Material at no additional cost to
HMRI consistent with directions received from the appropriate governmental
authority.  For the purposes of this Agreement, the expenses of recall shall
include, without limitation, the expenses of notification and destruction or
return of the recalled Material and all other costs incurred in connection with
such recall, but shall not include lost profits of either party.

          6.3  COMPLIANCE WITH THE FEDERAL FOOD, DRUG AND COSMETIC ACT.
Alliance warrants that all Material delivered to HMRI pursuant to this Agreement
will, at the time of such delivery, not be adulterated within the meaning of the
Federal Food, Drug and Cosmetic Act, as amended (the "Act"), or within the
meaning of any applicable state or municipal law as the Act and such laws are
constituted and effective at the time of delivery, and will not be an article
which may not, under the provisions of the Act, be introduced into interstate
commerce.  Notwithstanding anything to the contrary in this Section 6.3,
Alliance's warranty hereunder does not extend to any packaging or labeling
provided by, or at the direction of, HMRI.

                                   ARTICLE VII
                                 CONFIDENTIALITY

          7.1  NONDISCLOSURE OBLIGATIONS.  All confidential information
transmitted by either party to the other, including all confidential information
developed pursuant to this Agreement or the License Agreement, shall be
identified as confidential and the receiving party shall, while this Agreement
is in effect and for five years after termination thereof, make no use of this
information other than in furtherance of this Agreement or the License Agreement
and shall use the same efforts to keep secret and prevent the disclosure of such
information to parties other than its Affiliates, sublicensees, agents,
officers, employees and representatives authorized to receive such information
as it would for its own confidential information except for such confidential
information that,

               (a)  was known to the receiving party or its Affiliates or
sublicensees at the time of its disclosure and not previously subject to any
obligation of confidentiality at the time of its disclosure;

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

               (c)  became generally available to the public or became otherwise
part of the public domain after its disclosure and other than through any act or
omission of the receiving party or its Affiliates or sublicensees in breach of
this Agreement or the License Agreement; or

               (d)  became known to the receiving party or its Affiliates or
sublicensees after its disclosure (i) from a source other than the disclosing
party (including from dependent development by the receiving party), (ii) other
than from a Third Party who had an obligation to the disclosing party not to
disclose such information to others, and (iii) other than under an obligation of
confidentiality; or


                                       14

<PAGE>

               (e)  is disclosed by the receiving party pursuant to oral
questions, interrogatories, requests for information or documents, subpoena or
civil investigative demand issued by a court or governmental agency; PROVIDED,
that the receiving party notifies the other party immediately on receipt thereof
and the disclosing party furnishes only that portion of the confidential
information that counsel advises is legally required.

          7.2  DISCLOSURE OF CONFIDENTIAL INFORMATION.  Each receiving party or
its Affiliates or sublicensees may disclose any of the Know-How and confidential
information to the extent such disclosure is necessary to comply with applicable
laws or regulations, or to make and use Products (as defined in the License
Agreement) or Material in accordance with the terms of this Agreement and/or the
License Agreement.

          7.3  REVIEW OF PUBLICATIONS.  Each party recognizes the mutual
interest in obtaining valid patent protection.  Consequently, either party and
its employees or consultants or any other Third Party wishing to make a
publication (including any oral disclosure made without obligation of
confidentiality) relating to work performed by such party as part of the work
performed under this Agreement or the License Agreement (the "Publishing Party")
shall transmit to the other party (the "Reviewing Party") a copy of the proposed
written publication at least 45 days prior to submission for publication, or an
abstract of such oral disclosure at least 15 days prior to submission of the
abstract of the oral disclosure, whichever is earlier.  The Reviewing Party
shall have the right (a) to propose modifications to the publication for patent
reasons, (b) to request a delay in publication of presentation in order to
protect patentable information, or (c) to request that the information be
maintained as a trade secret and, in such case, the Publishing Party shall not
make such publication.  Each party shall designate an individual to whom
proposed publications shall be directed and such individual shall be responsible
for obtaining the necessary internal approvals of the Reviewing Party.

          7.4  DELAY OF PUBLICATIONS.  If the Reviewing Party requests a delay
as prescribed in subsection 7.3(b) the Publishing Party shall delay submission
or presentation of the publication for a period of up to 90 days to enable
patent applications protecting each party's rights in such information to be
filed.

          7.5  APPROVAL OF PUBLICATIONS.  Upon the receipt of written approval
of the Reviewing Party or the expiration of the applicable waiting period
without comment, the Publishing Party may proceed with the written publication
or the oral presentation.

          7.6  INJUNCTIVE RELIEF.  The parties hereto understand and agree that
remedies at law may be inadequate to protect against any breach of any of the
provisions of this Article 7 by either party or their employees, agents,
officers or directors or any other person acting in concert with it or on its
behalf.  Accordingly, each party shall be entitled to the granting of injunctive
relief by a court of competent jurisdiction against any action that constitutes
any such

                                       15

<PAGE>

breach of this Article 7.  It is understood that such injunctive relief is
intended solely as provisional relief pending the dispute resolution procedures
described in Article 10 herein.

          7.7  CONTRACTUAL PUBLICATION RIGHTS OF THIRD PARTIES.  Notwithstanding
the foregoing, the right of any party to withhold or delay consent to publish or
delay publication shall be subject to any contractual publication rights of
Third Parties involved in research or clinical trials for the Products or
Material, as the case may be.  The parties will use reasonable efforts to obtain
the voluntary consent of any Third Party with publication rights agreed to prior
to the Effective Date, to comply with the notice and timing requests in this
Article 7 and will promptly review any publications delivered for review.

                                  ARTICLE VIII
                          INDEMNIFICATION AND INSURANCE

          8.1  BY ALLIANCE.  Notwithstanding Alliance's right to indemnification
in the License Agreement, Alliance will indemnify and hold HMRI harmless against
any and all liability, damages, losses, costs or expenses ("Liability")
resulting from any Third Party claims made or suits brought against HMRI to the
extent such Liability arises from Alliance's failure to comply with the
Specifications, Alliance's gross negligence or willful misconduct in the
manufacture, storage, handling or shipping of Material or Alliance's breach of
any express warranty set forth in Article 6 hereof.

          8.2  BY HMRI.  Without limiting Alliance's right to indemnification in
the License Agreement, HMRI will indemnify and hold Alliance harmless against
any and all Liability resulting from (i) any packaging or labeling of any
Material to the extent that such packaging or labeling has been supplied by or
at the direction of HMRI and applied in accordance with instructions from HMRI
or (ii) any Third Party claims made or suits brought against Alliance to the
extent such Liability arises from HMRI's gross negligence or willful misconduct
in the storage, handling, shipping, use, marketing, distribution or sale of
Material.

          8.3  CONDITIONS OF INDEMNIFICATION.  A party or any of its Affiliates
or other respective employees or agents (the "Indemnitee") that intends to claim
indemnification under this Article 8 shall promptly notify the other party (the
"Indemnitor") of any Liability in respect of which the Indemnitee intends to
claim such indemnification reasonably promptly after the Indemnitee is aware
thereof, and the Indemnitor shall assume the defense of any related Third Party
action, suit or proceeding with counsel mutually satisfactory to the parties;
PROVIDED, HOWEVER, that an Indemnitee shall have the right to retain its own
counsel, with the fees and expenses to be paid by the Indemnitor, if
representation of such Indemnitee by the counsel retained by the Indemnitor
would be inappropriate due to actual or potential differing interests between
such Indemnitee and any other party represented by such counsel in such
proceedings.  The indemnity agreement in this Article 8 shall not apply to
