     MANY OF THE MATTERS SET FORTH IN THIS PROSPECTUS CONTAIN FORWARD-LOOKING
STATEMENTS THAT ARE SUBJECT TO RISKS AND UNCERTAINTIES THAT COULD CAUSE ACTUAL

                                    THE COMPANY

BUSINESS: Alliance Pharmaceutical Corp. is a pharmaceutical research and
          development company with three products in late-stage human (clinical)
          development, each of which is designed to address a different medical
          need. These products are based on our expertise with
          perfluorochemicals ("PFCs") and other technologies.  PFCs are man-made
          chemicals that can dissolve and carry oxygen and other gases, and may
          therefore be useful for delivering oxygen throughout the body, 
          including within the lung. PFCs have also been shown to be useful
          in enhancing ultrasound images.  

          We are also employing our adaptable core technologies to develop a
          new, versatile system for delivery of various types of drugs into the
          lungs for treatment of lung diseases and for distribution of 
          medications to other parts of the body.  In addition, we have other 
          products in early development. 

LEADING
PRODUCTS: OXYGENT is a temporary oxygen carrier to reduce or eliminate the need
          for human blood transfusions during elective surgeries where
          substantial blood loss is common. OXYGENT is a "blood substitute" that
          uses PFCs as raw materials, not human or animal blood. It therefore
          carries no risk of infectious disease, can be sterilized, is
          compatible with all blood types and has a shelf-life of approximately
          two years. Unlike other blood substitutes currently under development,
          OXYGENT is manufactured using cost-effective methods that we believe
          will allow us to market the product at a price that is competitive to
          that of donor blood.  A Phase 3 study is underway in Europe in order
          to assess whether the use of OXYGENT can reduce the need for donor
          blood in surgical patients.  We are also planning to conduct an
          additional Phase 3 study in the United States.  Phase 3 studies are
          typically the final human studies required prior to submission of a
          New Drug Application to the U.S. Food and Drug Administration (FDA)
          or foreign agency requesting approval to market a new drug.

          LIQUIVENT is a PFC liquid that is trickled directly into the lungs
          of a patient who is being supported by a mechanical ventilator. 
          LIQUIVENT therapy is expected to reduce the damage resulting from
          prolonged use of the ventilator, open up collapsed air sacs, assist in
          providing oxygen to and removing carbon dioxide from the lungs, and
          flush debris from the lungs. In human trials, the use of LIQUIVENT led
          to improvements in lung function and a decline in the number of days
          on a ventilator. We are currently conducting a Phase 3 clinical study
          in the U.S., Canada, and Europe to evaluate the use of LIQUIVENT
          for the treatment of adult patients with acute (sudden-onset) lung
          injury and acute respiratory distress syndrome. LIQUIVENT has been
          granted Subpart E ("fast track") status by the FDA; however, one or
          more additional studies may be required prior to filing a New Drug
          Application with the FDA.

                                       1

          IMAGENT is a PFC-based diagnostic agent intended for use with
          ultrasound diagnostic techniques to enhance real-time images of blood
          flow in the blood vessels, heart, and other organs.  Enrollment has
          been completed in Phase 3 studies in which IMAGENT was evaluated as a
          contrast agent to improve ultrasound images of the heart in cardiac
          patients.  The data from these studies is under analysis, and we are
          planning to submit a New Drug Application to the FDA in the second
          half of 1999.  In previous human studies, IMAGENT enhanced signals
          from blood vessels using gray-scale, color and Power Doppler, and
          harmonic ultrasound imaging methods. IMAGENT is being developed with
          Schering AG, Germany.

          PULMOSPHERES are drug-containing hollow, porous particles that are
          being developed for delivery of drugs to the lungs. The PULMOSPHERE
          particles may be suspended in PFCs or other propellants for delivery
          to the lungs via traditional inhalers and other devices. PULMOSPHERES
          have been formulated with a variety of drugs such as asthma
          medications, antibiotics, proteins and peptides.  Laboratory
          (non-human) studies are being conducted to evaluate the potential uses
          of PULMOSPHERES.

OTHER 
PRODUCTS: Our pipeline includes products in various stages of development:

          FLOGEL is a liquid/gel that is intended to reduce the occurrence of
          internal adhesions (scar tissue) in patients undergoing surgeries of
          their internal organs.  FLOGEL is applied as a cold liquid that
          becomes a gel at body temperature, forming a barrier that limits the
          formation of adhesions between tissues. Various drugs may be
          incorporated into FLOGEL for drug delivery and ophthalmic (eye)
          indications.

          RODA is a monitor intended to provide real-time measurements of the
          cardiovascular (heart and blood system) and oxygenation status of
          surgical patients.  We believe this monitor may provide important
          information during certain surgical procedures involving high blood
          loss, including those utilizing OXYGENT.  We are co-developing the
          RODA Monitor with our partner, VIA Medical Corporation.


STRATEGY: Our strategy is to (i) identify promising products on our own or with
          researchers and clinicians in universities and medical centers; (ii)
          use our scientific and medical expertise, research laboratories and
          production facilities, and manufacturing know-how to define suitable
          pharmaceutical formulations; (iii) design and conduct preclinical and
          clinical development programs; and (iv) oversee and fund product
          advancement into late-stage clinical development. Then, we seek to
          partner with a large pharmaceutical company for the final phase of
          human testing, worldwide regulatory approvals, manufacturing scale-up
          and marketing.

          During the past 16 months we resumed responsibility for the
          development of OXYGENT and LIQUIVENT due to differences in priorities
          and clinical development strategies with our former partners. This
          forced us to reallocate our human and capital resources. We are
          currently focusing on advancing the clinical studies with OXYGENT and
          LIQUIVENT, and we intend to seek new partners for both products, as
          well as for PulmoSpheres.

                                    RISK FACTORS

     Investing in our stock involves a high degree of risk.  You should
carefully consider the following risk factors and all other information
contained in this prospectus before purchasing our stock. Any of the following
risks could materially adversely affect our business, operating results and
financial condition and could result in a complete loss of your investment.

WE HAVE A HISTORY OF OPERATING LOSSES AND LIMITED PRODUCT REVENUES 

     We cannot assure you that we will become profitable at all or on a 
sustained basis.  Substantially all of our revenues to date have come from 
licensing fees, milestone payments and payments to fund research and 
development activities under joint development and license agreements.  We 
have had net operating losses since our inception and we expect such losses 
to continue until we receive revenues from product sales.  As of December 31, 
1998, we had an accumulated deficit of $292.0 million.  For the years ended 
June 30, 1996, 1997 and 1998, we incurred net losses of $23.2 million, $19.0 
million and $33.0 million, respectively.  Our net loss for the six months 
ended December 31, 1998 was $27.7 million.

WE HAVE FUTURE CAPITAL NEEDS AND ADDITIONAL FINANCING IS UNCERTAIN

     The costs of our current clinical trials are high.  We believe that our 
existing capital resources, including expected revenues from our Schering 
License Agreement for Imagent and investments, together with the proceeds 
from this offering (assuming we sell at least $20,000,000 of common stock), 
will satisfy our capital requirements through December 1999. We cannot be 
sure how many shares we will sell or how long our capital resources will last. 
In any event, we will need additional financing.  We intend to seek 
collaborative arrangements for OXYGENT, LIQUIVENT and PULMOSPHERES to help 
cover the cost of development. Our future capital requirements will depend on 
many factors, including:

     -  results of our late-stage clinical trials

     -  progress with pre-clinical testing 

     -  continued scientific progress in our research and development programs

     -  the time and cost involved in obtaining regulatory approvals

     -  changes in existing collaborative relationships

     -  patent costs

     -  competing technological and market developments

     -  the cost of manufacturing scale-up

     As of April 13, 1999 we have an outstanding bank loan in the amount of 
$14.1 million.  That loan is secured by certain assets, including equipment 
and machinery.  The loan requires us to have at all times cash, cash 
equivalents and receivables of at least $25 million.  As of March 1999, our 
cash, cash equivalents and receivables were below $25 million and we are in 
violation of our agreement with the bank.  Under our agreement, the bank may 
demand that we pay all of our loan 

                                      -5-

<PAGE>

in full or it may take possession of the assets that secure the loan. If we 
are forced to pay off our loan with existing cash, we may have to reduce, 
delay or terminate some of our development efforts.  The bank has indicated 
that if we raise $18 million, it will reduce the cash covenant to $10 
million (a portion of which will be held by the bank as collateral), take a 
lien on some of our patents and otherwise restructure the loan payments.

     We cannot assure you that we will have access to adequate financing in the
future or that any prospective financing will be on terms we find acceptable.

SUCCESS OF PARTNERING STRATEGY IS UNCERTAIN

     Our strategy is to enter into license agreements to support the 
development, commercialization and costs of our products. In May 1998, we 
restructured our existing partnership agreement for OXYGENT with Ortho 
Biotech, Inc., a division of Johnson & Johnson, following our failure to 
reach agreement as to the scope and timing of further clinical development, 
including whether to proceed with Phase 3 trials at that time. Under the 
restructured agreement, we have full responsibility, including costs, for 
worldwide development of OXYGENT. Ortho has a limited option to reacquire the 
rights to market OXYGENT.

     Under our Schering license agreement for IMAGENT, we depend on Schering for
development and regulatory approvals outside the United States and for worldwide
marketing of IMAGENT. As of December 30, 1998, the Schering license agreement
was modified to reduce ongoing development reimbursement, add new milestone
payments and restructure the methods for calculating royalties.  The Schering
license agreement may not be terminated until September 1999; however,
thereafter, it may be terminated on one month's advance notice.  A termination
of the Schering license agreement could adversely affect our research,
development and, ultimately, marketing of IMAGENT. 

     Our current partnering strategy is to seek new collaborations for 
OXYGENT and LIQUIVENT and a similar agreement for PULMOSPHERES.  However, we 
cannot assure you that we will be able to negotiate acceptable collaborative 
arrangements in the future, or that any current or future arrangements will 
ultimately be successful.  Even if successful, we may not be able to 
completely control the amount and timing of resources our collaborative 
partners will devote to these activities.  Failure to license our products 
could have a serious impact on our development strategy and could materially 
impact our financial condition.

WE ARE IN ARBITRATION WITH A FORMER PARTNER

     In December 1997, our former partner for LIQUIVENT, Hoechst Marion 
Roussel, Inc. (which we refer to as "HMR"), terminated its license agreement 
with us.  We regained all rights to and responsibilities for the product.  In 
May 1998, HMR asked us to pay them up to $7.5 million, payable in cash or 
stock.  On September 25, 1998, we received a demand for arbitration from HMR, 
claiming up to $16.8 million, plus interest and punitive damages, in 
connection with the termination of the HMR license agreement.  We have filed 
a counterclaim against HMR. We do not believe its claim is valid.  We intend 
to contest HMR's claim and believe that the ultimate resolution will not have 
a material adverse effect on our business. However, no assurance can be given 
that we will prevail on the claim or that an adverse result will not have a 
material adverse effect on our business.

                                      -6-

<PAGE>

THE RESULTS OF CLINICAL TRIALS AND OF GOVERNMENTAL REGULATION ARE UNCERTAIN

     Clinical trials, manufacturing and marketing of our 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 our products do not demonstrate that they 
are safe and effective, we will not be able to submit to the FDA a New Drug 
Application ("NDA") or other relevant applications for pre-market approval.  
Further, the results of preclinical testing and initial clinical trials do 
not necessarily predict how safe and effective a product will be when it is 
evaluated in large-scale Phase 3 clinical trials.  It is possible that 
unacceptable side effects may be discovered at any time. A number of 
companies have suffered significant setbacks in advanced clinical trials, 
despite promising results in earlier trials.

     The rate of completion of the clinical trials for our products depends on
many factors, including obtaining adequate clinical supplies and the rate of
patient recruitment.  Patient recruitment is a function of many factors,
including the size of the patient population, the proximity of patients to
clinical sites, and the eligibility criteria for patients who may enroll in the
trial.  We may experience increased costs, program delays, or both, if there are
delays in patient enrollment in the clinical trials.

     Even if we believe the clinical trials demonstrate the safety and 
efficacy of a product, the FDA and other regulatory authorities may not 
accept our assessment of the results.  The FDA has required other companies 
involved in the development of blood substitutes to increase the size of 
their Phase 3 trials, extending the time and cost to complete the trials.  In 
any case, in order to demonstrate the safety and efficacy of the products we 
may have to conduct additional clinical trials beyond those currently 
planned.  The process of obtaining regulatory clearances or approvals is 
costly and time-consuming.  We cannot predict how long preclinical and 
clinical trials will take or whether they will be successful.

     We will not be able to commercialize our products until we have acceptable
clinical trial results and regulatory approval.  We cannot assure you that the
clinical trial results will be favorable or that we will be able to obtain
regulatory approval for commercialization of any of our products.  We also
cannot predict the effect of new governmental regulations.

     As of the date of this prospectus, we have not agreed with the FDA on 
the design for the U.S. Phase 3 clinical trial for Oxygent.

WE HAVE LIMITED MANUFACTURING CAPABILITY

     While we believe that we can produce materials for clinical trials and 
the initial market launch for OXYGENT and IMAGENT at our existing San Diego 
facilities and for LIQUIVENT at our Otisville, New York facility, we may need 
to expand our commercial manufacturing capabilities for 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.

     We have not selected a site for the expanded facilities and cannot predict
the amount we will expend for the construction of such facilities.  We cannot be
sure whether the FDA will determine that such facilities comply with Good
Manufacturing Practices.  The projected location and construction of such
facilities will depend on regulatory approvals, product development, and 

                                      -7-

<PAGE>

capital resources, among other factors.  We have not obtained any regulatory 
approvals for our production facilities for these products, nor can we assure 
you that we will be able to do so.

     The Schering license agreement requires us to manufacture IMAGENT at our
San Diego facility for a period of time after market launch and to sell the
product to Schering at a negotiated price.

UNPREDICTABILITY OF PATENT PROTECTION AND PROPRIETARY TECHNOLOGY

     We believe that our success will depend largely on our ability to obtain
and maintain patent protection for our own inventions, and to license the use of
patents owned by third parties.  We have obtained patents covering certain
intermediate and high concentration PFC emulsions, patents related to liquid
ventilation, and patents covering certain stabilized microbubble compositions,
as well as other patents.  We have filed, and when appropriate will file, other
patent applications with respect to our products and processes in the United
States and in foreign countries.  We cannot assure you, however, that we will
develop any additional products and processes that will be patentable or that
any additional patents will be issued to us.  It is possible that any of our
patents or any patents licensed to us may be challenged successfully.  It is
also possible that we may unintentionally infringe on patents of third parties,
or that we may have to alter our products or manufacturing processes to take
into account the patents of third parties and this may cause delays in product
development. Further, we cannot assure that we will be able to alter our
products or manufacturing processes to avoid third party patents, in which case
we may have to terminate the development or commercialization of a product or
pay royalties to the holders of the patents.  Litigation, which could result in
a substantial cost to us, may be necessary to enforce any patents we own and/or
to determine the scope and validity of others' proprietary rights.  We also
attempt to protect our proprietary products and processes by relying on trade
secret laws and non-disclosure and confidentiality agreements with our employees
and certain other persons who have access to our products or processes.  It is
possible that others will develop such products or processes independently or
obtain access to such products or processes.  Our competitive position may be
affected adversely if others develop or obtain products or processes similar to
ours.

     In particular, with respect to ultrasound contrast imaging patents, there
are several companies with issued patents and other patent applications in
process.  Many of these patents overlap each other, and it will take several
years to clarify which ones are valid and enforceable.  Although we believe we
have the right to manufacture, use and sell IMAGENT once it is approved, it is
possible that we may need to license rights under patents owned by others, and
that such rights may not be available.  Other companies may well find that their
current or future activities violate our patents.  We believe certain companies
have obtained patents to which they are not entitled under U.S. law, and have
requested patent interference proceedings in the U.S. Patent Office to resolve
those issues. 

WE RELY ON OTHER PARTIES FOR RAW MATERIALS

     Some of the raw materials for our products are available from single
sources.  At times, one or more of these raw materials may not be available or
may be available only in limited quantities.  Our ability to develop our
products could be materially adversely affected if sufficient 

                                      -8-

<PAGE>

supplies of raw materials are not available. We are currently negotiating 
with some of these suppliers for long-term supply contracts for raw 
materials; however, we cannot be sure we will be able to obtain commitments 
for a long-term supply of these raw materials on acceptable terms.

OUR PRODUCTS ARE IN THE DEVELOPMENT STAGE

     Our products require substantial development efforts. We or our
collaborative partners may encounter unforeseen technological or scientific
problems, including adverse side effects, which may force us to abandon or
substantially change the plan of development of a specific product or process.
A technological change or product development by others may also have a
significant adverse effect on our operations.  Further, even after successful
technical development and receipt of governmental approval, a product may not
achieve commercial success.

WE LACK SALES AND MARKETING CAPABILITY

     We do not have internal marketing and sales capabilities.  Our strategy is
for our current and future collaborative partners to market and sell any
products that we may successfully develop.

     Should we have to market and sell our products directly, we would need to
develop a marketing and sales force with technical expertise and distribution
capability.  The creation of infrastructure to commercialize pharmaceutical
products is an expensive and time-consuming process.

     We cannot assure you that we will be able to establish marketing and sales
capabilities or be successful in gaining market acceptance for our products.  To
the extent that we enter into co-promotion or other licensing arrangements, any
revenues we receive will be dependent on the efforts of third parties.

UNCERTAINTY OF THIRD-PARTY REIMBURSEMENT

     Our ability to commercialize our products successfully will depend in part
on the extent to which the cost of the products and related treatment will be
reimbursed by government authorities, private health insurers and other
organizations, such as 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 healthcare 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 our
products.  The cost containment measures that healthcare providers are
instituting and any healthcare reform could affect our ability to sell our
products and may have a material adverse effect on our operations.  We cannot
assure you that reimbursement in the United States or foreign countries will be
available for any of our 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 reduce the price of, our products. The lack
or inadequacy of third-party reimbursement for our products would have a
material adverse effect on our operations.  We cannot forecast what additional
legislation or regulation relating to the 

                                      -9-

<PAGE>

healthcare industry or third-party coverage and reimbursement may be enacted 
in the future, or what effect the legislation or regulation would have on our 
business.

WE DEPEND ON KEY PERSONNEL

     Our ability to develop successful products and to achieve a competitive 
position will depend, in part, on our ability to attract and retain qualified 
scientific and management personnel.  Competition for such personnel is 
intense. We cannot assure you that we will be able to attract and retain such 
personnel. Some of our scientific advisors are employed by, or have 
consulting arrangements with, third parties that may conflict with their 
obligations with us.  We will require additional expertise and expect to 
place additional demands on our management and financial resources. 

WE MAY BE AT A COMPETITIVE DISADVANTAGE

     We cannot assure you that we will be able to compete successfully.  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 address the same
markets as, our products.  Many of our existing or potential competitors have
substantially greater financial, technical and human resources than we do 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 ours.  In addition, our products and technologies may be rendered
uncompetitive or obsolete by the development of other technologies or products
that have an entirely different approach or means of accomplishing the same
purposes.

POTENTIAL PRODUCT LIABILITY CLAIMS AND UNINSURED RISKS

     Products or processes that we may develop, license, or sell may expose us
to potential liability.  Liability of this type could arise from claims by users
of our products or of products manufactured by processes we developed, or from
manufacturers or others selling our products, either directly or as a component
of other products.  We currently maintain limited product liability insurance
coverage.  We cannot assure you that we will be able to maintain this coverage
or obtain additional coverage on acceptable terms, or that insurance will
provide adequate coverage against all potential claims.

VOLATILITY OF STOCK PRICE

     Historically, the market price of our stock has been highly volatile.  The
following types of announcements could have a significant impact on the price of
our stock:

     -    positive or negative results of testing and clinical trials

     -    amount and terms of future financings

     -    technological innovations or commercial product introductions by
          ourselves or competitors

     -    changes in government regulations

                                      -10-

<PAGE>

     -    developments concerning proprietary rights, including patents and
          litigation matters

     -    failure to enter into a collaborative partnership for OXYGENT,
          LIQUIVENT or PULMOSPHERES

     -    change in the status of the Schering licensing agreement 

     -    public concern relating to the commercial value or safety of any of
          our products

     -    general stock market conditions

     Further, the stock market has in recent months experienced and may continue
to experience significant price and volume fluctuations.  These fluctuations
have particularly affected the market prices of equity securities of many
biopharmaceutical companies.  Often, the effect on the price of such securities
is unrelated or disproportionate to the operating performance of such companies.

WE HAVE SECURITIES THAT ARE ENTITLED TO A LIQUIDATION PREFERENCE

     We currently have 500,000 shares of Series D Preferred Stock outstanding
entitled to a liquidation preference of $20 per share.  We also have 52,163
shares of the Series E-1 Preferred Stock outstanding entitled to a liquidation
preference of $60 per share.

WE DO NOT INTEND TO PAY DIVIDENDS; WE MAY ISSUE ADDITIONAL PREFERRED STOCK

     We have never paid dividends on our common stock and do not intend to pay
any dividends in the foreseeable future.  Our Board of Directors has the
authority to issue up to an additional 2,947,837 shares of preferred stock and
may determine the rights, preferences, privileges and restrictions of such
shares without any further vote or action by the shareholders.  The rights of
the holders of our common stock (and any outstanding shares of preferred stock)
will be subject to, and may be adversely affected by the rights of the holders
of any preferred stock that may be issued in the future.  The possible issuance
of preferred stock could have the effect of delaying, deferring or preventing a
change in control of Alliance.  The conversion and other features of any series
of preferred stock may also limit the price that investors might be willing to
pay in the future for shares of our common stock.

SHARES ELIGIBLE FOR FUTURE SALE COULD ADVERSELY AFFECT STOCK PRICES AND
ADDITIONAL EQUITY ISSUANCES

     As of April 13, 1999, 6,203,541 shares of our common stock (or 15.8% of the
total number of shares outstanding on a fully diluted basis) were issuable upon
the exercise of outstanding options and warrants.  Additional shares may be
issued upon the conversion of preferred stock.  Also, over a period of
approximately four years, we may issue an indeterminate number of additional
shares of our common stock to the former shareholders of MDV Technologies, Inc.,
a company we acquired in 1996.  The existence of such warrants, options and
convertible securities, as well as certain registration rights, may adversely
affect the terms on which we may obtain additional equity financing and the
aftermarket trading of our stock.  The holders of the outstanding warrants and
options are likely to exercise their securities at a time when we would
otherwise be able to obtain capital on terms more favorable than those provided
by the exercise or conversion prices thereof.

                                      -11-

<PAGE>

RISKS ASSOCIATED WITH PREFERRED STOCK FINANCING

     In August 1998, we raised net proceeds of $5.6 million through the 
issuance of Series E-1 Preferred Stock. In January 1999, the holders of 
47,837 shares of Series E-1 Preferred Stock converted such shares into 
1,091,338 shares of common stock at a price of $2.63 per share.  Today, 
52,163 shares of Series E-1 Preferred Shares remain outstanding.  The 
remaining Series E-1 Preferred Stock is convertible into shares of the our 
common stock based on the trading prices of the common stock during future 
periods that are described in the certificate of designation. Therefore, we 
presently are unable to determine the number of shares of our common stock 
that we may ultimately need to issue upon conversion. If the holders of the 
remaining Series E-1 Preferred Stock convert when the trading price of our 
common stock is low, we would need to issue a large number of shares of our 
common stock upon conversion and this could result in substantial dilution to 
the holders of our common stock.

     Certain provisions set forth in the stock purchase agreement for the Series
E-1 Preferred Stock prohibit us from: 

       -  declaring, authorizing or setting aside or paying any dividend or
          other distribution with respect to our common stock

       -  repaying, repurchasing or offering to repay, repurchase or otherwise
          acquire shares of our common stock in any manner

       -  issuing any series of preferred stock or other securities with rights
          senior (in respect of liquidations, dividends, preferences and similar
          rights) to those of the Series E-1 Preferred Stock

     The certificate of designation filed in connection with the issuance of the
Series E-1 Preferred Stock also includes certain penalty provisions that are
triggered if we fail to satisfy certain obligations.  We may incur substantial
financial penalties if we fail to comply with such terms.  We cannot assure you
that we would be able to fund such penalties, and even if funding is available,
the payment of such penalties could adversely affect our business and financial
condition.

YEAR 2000 ISSUES

     Many currently installed operating systems and software products are coded
only to accept two digit entries in the date code field.  Consequently, they are
unable to distinguish 21st century dates from 20th century dates.  As a result,
the computer systems and software used by many companies may need to be upgraded
to prevent problems that would result from misreading the entries in the date
code field.  Failure to correct systems to become "Year 2000 compliant" may
result in systems failures or miscalculations causing disruptions of operations,
including, among other things, a temporary inability to process data, send
invoices or engage in similar normal business activities.

     We are currently reviewing the potential impact of Year 2000 issues on our
business and attempting to mitigate or eliminate those issues.  The primary
risks to us are those of business continuity.  We are determining which
equipment we own needs to be replaced.  We have also 

                                      -12-

<PAGE>

begun communicating with our significant suppliers, financial institutions, 
insurance companies and other parties that provide us significant services, 
including clinical trial sites, to determine whether they anticipate Year 
2000 problems in their operations.  If we or our significant vendors or 
suppliers are unable to become Year 2000 compliant in time, this could have a 
material adverse effect on our ability to continue our operations.

                                      -13-

                        WHERE YOU CAN FIND MORE INFORMATION

     We have filed with the SEC a registration statement on Form S-3 (the
"Registration Statement") under the Securities Act, with respect to the shares
offered in this prospectus.  This prospectus does not contain all the
information set forth in the Registration Statement and exhibits thereto,
certain portions of which have been omitted as permitted by the rules and
regulations of the SEC.  Copies of the Registration Statement (including the
omitted portions) are available from the SEC upon payment of prescribed rates. 
For further information, reference is made to the Registration Statement and the
exhibits filed therewith.  Statements contained in this prospectus or the
Registration Statement relating to the contents of any contract or other
document filed as an exhibit to the Registration Statement are not necessarily
complete, and in each instance are qualified in all respects by the full text of
such contract or document.

     You should rely only on the information or representations provided in this
prospectus or incorporated by reference.  We have not authorized anyone else to
provide you with different information.  The selling stockholders have agreed
not to make an offer of the shares of our common stock in any state where the
offer is not permitted.  You should not assume that the information in this
prospectus is accurate as of any date other than the date on the cover page.

                                  USE OF PROCEEDS

     We plan to use the majority of the net proceeds from this offering to fund
late-stage clinical trials of OXYGENT and LIQUIVENT and to prepare a New Drug
Application filing package for IMAGENT.  The balance of the net proceeds will be
used for working capital and other general corporate purposes and limited
research and development for PULMOSPHERES. The amounts actually expended for
each purpose and the timing of such expenditures may vary significantly
depending upon various factors including, but not limited to, the results and
timing of our clinical development, the launch of new products, governmental or
regulatory changes, the role of corporate partners and technological advances
and competition by others.  In addition, there can be no assurance that any
product developed or introduced by us will be commercialized or that funds will
be sufficient to develop successful products. 

     We expect to use all of the net proceeds from this offering for the
purposes described above, and we will require substantial additional funds in
the future in order to continue our development programs and to manufacture and
market any future products.  We anticipate that existing cash balances and
interest income thereon, together with the net proceeds of this offering will be
adequate to satisfy our capital requirements through December 1999 (assuming 
we raise at least $20,000,000).

                                      -15-

<PAGE>

     Pending such uses, we intend to invest the net proceeds of this offering in
short-term, investment grade securities.

                                      DILUTION

     As of December 31, 1998, the net tangible book value of Alliance was 
approximately $42.3 million, or $1.20 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 into common stock at an assumed 
weighted average conversion price of $4.86 per share).  After giving effect 
to the sale of the 10,000,000 shares of common stock offered in this offering 
at a public offering price of $2.75 per share, the pro forma net tangible 
book value of the common stock as of December 31, 1998 (after deducting the 
placement fees and estimated expenses of this offering) would have been 
approximately $67.6 million, or $1.49 per share. This represents an immediate 
increase in net tangible book value of $0.29 per share to existing 
shareholders and an immediate dilution of $1.26 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, 1998 as adjusted to give effect to the sale of 10,000,000 
shares in this offering.

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

<TABLE>

- --------------------------------------------------------------------------------
Public offering price per share                                      $2.75
- --------------------------------------------------------------------------------
Net tangible book value per share as of Decemeber 31, 1998           $1.20
- --------------------------------------------------------------------------------
Increase to present shareholders attributable to this offering       $0.29
- --------------------------------------------------------------------------------
Pro forma net tangible book value per share after this offering      $1.49

Dilution to investors in this offering                               $1.26
- --------------------------------------------------------------------------------
</TABLE>


     To the extent fewer than 10 million shares are sold in this offering, 
the dilution to new investors would be increased.

                                PLAN OF DISTRIBUTION

     We are offering the common stock on a best efforts basis only to 
selected institutional and other investors.  However, we cannot be certain 
that we will be able to sell all of the shares offered, and it is possible 
that we will close this offering for less than the 10,000,000 shares being 
offered.

                                      -16-

<PAGE>

     All investor funds will be deposited into an escrow account established 
on the investors' behalf pending effectiveness of the registration statement 
and issuance of the shares.  No investor funds may be accepted by us until 
the registration statement is declared effective. We will deposit the shares 
with the Depository Trust Company upon receiving a notice from the escrow 
agent.  The shares will then be credited to the respective accounts of the 
investors.

     If, for any reason, the offering is terminated, then all funds that were
deposited into escrow will be returned to investors.

     Cruttenden Roth Incorporated has agreed to act as placement agent in 
connection with the offering, to solicit indications of interest from 
investors. Cruttenden Roth has no obligation to buy any shares in the 
offering.

     We have agreed to pay Cruttenden Roth a fee up to 7.5% of the proceeds 
of this offering.  In addition, we will issue to Cruttenden Roth at the 
closing of the offering, warrants to purchase common stock in an amount up to 
10% of the shares of common stock sold in this offering to investors 
solicited by Cruttenden Roth.  The warrants will be exercisable for a period 
of five years from the closing of the offering with an exercise price equal 
to 120% of the public offering price per share.  We also agreed to reimburse 
Cruttenden Roth for its expenses that it incurs in connection with the 
offering and to indemnify Cruttenden Roth against certain liabilities under 
the Securities Act.  The Chairman and Chief Executive Officer of Cruttenden 
Roth is the brother of both the President and the Chief Executive Officer of 
Alliance.
                                          
                                   LEGAL MATTERS

     The legality of the issuance of the shares of common stock offered 
hereby will be passed upon for Alliance by Stroock & Stroock & Lavan LLP.

financial statements included in our annual report on Form 10K/A for the year

Note 1 to the consolidated financial statements), which is incorporated by

financial statements are incorporated by reference in reliance on Ernst & 
Young LLP's report, given on their authority as experts in accounting and

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 

                                      -1-

<PAGE>

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)  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.

     (c)  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.

     (d)  The undersigned registrant hereby undertakes:

               (1)  To file, during any period in which offers or sales are
being made, a post-effective amendment to this registration statement;

                    (i)   To include any prospectus required by Section 10(c)(3)
of the Securities Act of 1933;

                    (ii)  To reflect in the prospectus any facts or events
arising after the effective date of the registration statement (or the most
recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in the
registration statement; 

                    (iii) To include any material information with respect to
the plan of distribution not previously disclosed in the registration statement
or any material change to such 

                                      -2-

information in the registration statement.

               PROVIDED, HOWEVER, that paragraphs (d)(1)(i) and (d)(1)(ii) do
not apply if the registration statement is on Form S-3, Form S-8, and the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the registrant pursuant to
Section 13 or 15(d) of the Securities and Exchange Act of 1934 that are
incorporated by reference in the registration statement.

               (2)  That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment 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.

               (3)  To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.
