                               GENERAL INFORMATION

         This Proxy Statement is furnished in connection with the solicitation
of proxies by the Board of Directors of Alliance Pharmaceutical Corp. (the
"Corporation") to be voted at the Annual Meeting of Shareholders to be held on
Wednesday, November 11, 1998, at 10:00 a.m. at offices of the Corporation at
6175 Lusk Boulevard, San Diego, California 92121 and at any adjournment or
adjournments thereof (the "Meeting") for the purposes set forth in the
accompanying Notice of Annual Meeting of Shareholders.

         The mailing address of the principal executive offices of the
Corporation is 3040 Science Park Road, San Diego, CA 92121 (telephone number
619/558-4300). The enclosed Proxy and this Proxy Statement are being first sent
to shareholders of the Corporation on or about October 7, 1998.

         The Board of Directors has fixed the close of business on September 29,
1998 as the record date for the determination of shareholders of the Corporation
entitled to receive notice of, and vote at, the Meeting. At the close of
business on the record date, an aggregate of 32,042,482 shares of common stock,
par value $.01 per share, of the Corporation (the "Common Stock") were issued
and outstanding, each of which is entitled to one vote on each matter to be
voted upon at the Meeting, 500,000 shares of Series D Preferred Stock, par value
$.01 per share, of the Corporation (the "D Stock") were issued and outstanding,
each of which is entitled to one vote on each matter to be voted upon at the

share, of the Corporation (the "E-1 Stock") were issued and outstanding, each of
which is entitled to ten votes on each matter to be voted upon at the Meeting.
The Common Stock, D Stock and E-1 Stock vote together as one class.

         All votes will be tabulated by the inspector of election appointed for
the Meeting, who will separately tabulate affirmative and negative votes,
abstentions and broker non-votes. Abstentions will be counted towards the
tabulation of votes cast on proposals presented to the shareholders and will
have the same effect as negative votes. Broker non-votes are not counted for any
purpose in determining whether a matter has been approved.

SOLICITATION AND REVOCATION

         PROXIES IN THE FORM ENCLOSED ARE SOLICITED BY, OR ON BEHALF OF, THE
BOARD OF DIRECTORS OF THE CORPORATION. THE PERSONS NAMED IN THE PROXY HAVE BEEN
DESIGNATED AS PROXIES BY THE BOARD OF DIRECTORS. Shares represented by properly
executed proxies received by the Corporation will be voted at the Meeting in the
manner specified therein or, if no specification is made, will be voted FOR the
election of the nine directors listed herein, FOR the adoption of an increase in
the number of shares of Common Stock authorized for issuance, and FOR the
ratification of the appointment by the Corporation's Board of Directors of Ernst
& Young LLP as independent auditors of the Corporation for its fiscal year
ending June 30, 1999, all as described in this Proxy Statement.

         Any proxy given by a shareholder pursuant to this solicitation may be
revoked by the shareholder at any time before it is exercised, by written
notification delivered to the Secretary of the Corporation, by voting in person
at the Meeting, or by executing another proxy bearing a later date.

<PAGE>
                                       
         Proxies will be solicited by mail. They may also be solicited by
officers and regular employees of the Corporation personally, by telephone or
otherwise, but such persons will not be specifically compensated for such
services. The Corporation may use the services of Shareholder Communications
Corporation to aid in the solicitation of proxies. The Corporation estimates
that the fee payable to Shareholder Communications Corporation for such services
should not exceed $6,000. Banks, brokers, nominees and other custodians and
fiduciaries will be reimbursed for their reasonable out-of-pocket expenses in
forwarding soliciting material to their principals, the beneficial owners of
Common Stock. The costs of soliciting proxies will be borne by the Corporation.

                            1. ELECTION OF DIRECTORS

         Nine directors are to be elected at the Meeting to hold office until
the next annual meeting of shareholders and until the election and qualification
of their respective successors. The Board of Directors has nominated Pedro
Cuatrecasas, M.D., Carroll O. Johnson, Stephen M. McGrath, Donald E. O'Neill,
Helen M. Ranney, M.D., Duane J. Roth, Theodore D. Roth, Jean G. Riess, Ph.D.,
and Thomas F. Zuck, M.D., all of whom are currently directors of the
Corporation. Directors are elected by a plurality vote.

         Unless otherwise specified in the accompanying proxy, the shares voted
pursuant thereto will be cast for these nominees. If, for any reason, any of the
nominees should be unable to accept nomination or election, it is intended that
such proxy will be voted for the election, in his or her place, of a substituted
nominee who would be recommended by management. Management, however, has no
reason to believe that any nominee will be unable to serve as a director.

EMPLOYMENT ARRANGEMENTS

         During fiscal 1992, in connection with his relocation, the 
Corporation loaned Theodore Roth $175,000, which was originally due on August 
5, 1994. The loan bears interest at the prime rate reported in THE WALL 
STREET JOURNAL and had an outstanding principal balance of $150,000 as of 
that date. The loan is evidenced by a promissory note secured by real estate 
and an assignment of Mr. Roth's option to purchase stock of the Corporation. 
On February 16, 1994, the Board of Directors authorized the Corporation to 
forgive on December 1, 1994 and each December 1 thereafter, through December 
1, 1998, $30,000 of principal and all accrued interest through such date; 
provided Mr. Roth remains employed by the Corporation. If his termination is 
without cause by the Corporation or as a result of a change in control of the 
Corporation, the debt will be forgiven in full. Termination of his employment 
for any other reason requires the debt to be paid three years from the 
termination date, with interest. The largest outstanding balance due since 
the beginning of the last fiscal year was $65,100, and the balance 
outstanding as of September 4, 1998, is $31,700.

         On June 1, 1995, the Corporation loaned Simon Faithfull $70,000. The 
loan accrues interest at the rate of nine percent per annum. The loan is due 
and payable on demand; provided that unless and until demand is made, 
principal and interest shall be payable in biweekly installments of $500 
each. The largest outstanding balance due since the beginning of the last 
fiscal year WAS $70,315, and the outstanding balance as of September 4, 1998, 
is $64,183. The note is secured by a lien on Dr. Faithfull's primary 
residence.

STOCK OPTION GRANTS AND EXERCISES

         The Corporation has granted options to its executive officers under 
its 1983 Incentive Stock Option Plan (which plan expired on October 1, 1993), 
its 1983 Non-Qualified Stock Option Program, and its 1991 Stock Option Plan. 
No stock appreciation rights ("SARs") have been granted by the Corporation.

         The following table sets forth certain information concerning

(2)  All options granted in 1998 to the Named Executive Officers were
     non-qualified stock options under the 1991 Plan.

(3)  Options are exercisable in increments of 20%, 20%, 20% and 40% commencing
     one year after the date of issuance and on each subsequent anniversary,
     respectively.

(4)  The exercise price per share of the options granted represented the fair
     market value of the underlying shares on the date of grant. Options may be
     exercised by (i) paying the Corporation at least the par value of the
     shares of Common Stock being acquired, allowing the remainder of the
     exercise price to be borrowed from the Corporation, or (ii) by surrendering
     shares of Corporation Common Stock in payment of the exercise price and
     applicable withholding taxes. The 1991 Plan provides that loans to pay the
     exercise price shall mature within five years (or earlier, in the event of
     a termination of employment or of a consultancy), shall be secured by the
     shares of Common Stock purchased, shall provide for quarterly payments of
     interest at such rate as the Board of Directors may determine, and shall be
     in such form and contain such other provisions as the Board of Directors
     may determine from time to time.

COMPENSATION COMMITTEE REPORT

         The Compensation Committee of the Board of Directors (the 
"Committee") has provided the following report:

         The Committee is composed entirely of outside, nonemployee 
directors. The Committee determines the base salaries and the amount of bonus 
awards to be paid to the executive officers of the Corporation. In addition, 
the Committee recommends the number of the Corporation's stock option grants 
which should be made to executive officers and other employees of the 
Corporation. The following is a summary of policies of the Committee that 
affect the compensation paid to executive officers, as reflected in the 
tables and text set forth elsewhere in the proxy statement.

EXECUTIVE COMPENSATION POLICY AND COMPONENTS OF COMPENSATION

         The Committee's fundamental executive compensation philosophy is to 
enable the Corporation to attract and retain key executive personnel and to 
motivate those executives to achieve the Corporation's objectives. The 
Corporation is still in its research and development phase and has not yet 
achieved profitability. Therefore, traditional methods of evaluating 
executive performance, such as sales and profit levels, return on equity, and 
stock price, are inappropriate. Accordingly, 


                                      9


<PAGE>

assessment of each executive's performance is based upon attainment of his or 
her specific objectives in relation to the Corporation's overall annual 
strategic goals. The Committee may in its discretion apply different measures 
of performance for future fiscal years. However, it is presently contemplated 
that all compensation decisions will be designed to further the fundamental 
executive compensation philosophy described above.

         Each executive officer's compensation package is reviewed annually 
and is comprised of three components: base salary, bonus, and stock option 
grants. In addition, executive officers of the Corporation are eligible to 
participate in all benefit programs generally available to other employees.

BASE SALARY

         In setting the base salary levels of each executive officer, the 
Committee considers the base salaries of executive officers in comparable 
positions in other similarly situated biotechnology/pharmaceutical 
development companies. In setting levels, the Corporation currently targets 
the 75th percentile of the relevant labor market. Factors considered include 
company size, stage of development of a company's products, and geographical 
location. The Committee also considers the individual experience level and 
actual performance of each executive officer in view of the Corporation's 
needs and objectives. Salary decisions are determined in a structured annual 
review by the Committee with input from the Chief Executive Officer.

BONUSES

         Annual bonus, set as a targeted percentage of total cash 
compensation, may be earned by each executive officer, based upon the 
achievement of performance goals established at the beginning of the fiscal 
year and reviewed at least twice during the year.

         Performance goals for the Corporation are developed by management, 
and reviewed and approved by the Committee and the Board of Directors. 
Performance goals for individual executives are developed by the Chief 
Executive Officer, and reviewed and approved by the Committee. Bonuses are 
awarded to executives based upon the attainment of these goals during the 
year, with the Corporation and the executives accomplishing minimum 
objectives prior to being eligible to receive bonus. The Committee considers 
the amounts of bonuses it expects to pay to executives when it compares its 
compensation practices with other companies similarly situated.

LONG-TERM STOCK-BASED INCENTIVE COMPENSATION

         Generally, the Corporation's Board of Directors or, if appointed, a 
stock option committee, approves annual grants of stock options to each of 
the Corporation's executive officers under the 1991 Plan based upon 
recommendations from the Committee. The grants are designed to align the 
interest of each executive officer with those of the shareholders and provide 
each individual with a significant incentive to manage the Corporation from 
the perspective of an owner with an equity stake in the business. Each grant 
generally allows the officer to acquire shares of the Corporation's Common 
Stock at a fixed price per share (the market price on the grant date) over a 
specified period of time (up to ten years), thus providing a return to the 
executive officer only if the market price of the shares appreciates over the 
option term. The size of the option grant to each executive officer generally 
is set as the Committee deems appropriate in order to retain and motivate key 
executive officers as well as to provide them with the perspective of the 
Corporation's shareholders in assessing corporate results. The grants also 
take into account comparable awards to individuals in similar positions at 
biotechnology/pharmaceutical development companies as reflected in external 
surveys, the individual's potential for future responsibility and promotion 
over the option term, the individual's personal performance in recent 
periods, and the risk attached to the future growth of the pharmaceutical 
industry. In making comparisons in the industry, the Corporation targets the 
75th percentile of the relevant labor market.

         The Committee, at its discretion, has the authority to utilize 
compensation consultants to assist in defining the relevant labor market for 
executive compensation and to recommend annual salary and bonus increases.

         Duane J. Roth, Chief Executive Officer, although not a member of the 
Committee, assisted the Committee in developing the compensation packages 
awarded to executive officers other than himself.

CEO COMPENSATION

         In setting the compensation payable to the Corporation's Chief 
Executive Officer, the Committee sought to be competitive with other 
biotechnology/pharmaceutical development companies. In making comparisons, 
the Corporation targets the 75th percentile of the relevant labor market. The 
Committee established Duane Roth's base salary based on an evaluation of his 
personal performance and the objective of having his base salary keep pace 
with salaries being paid to similarly situated chief executive officers. With 
respect to his base salary, it is the Committee's intent to provide him with 
a level of stability and certainty each year and not have this particular 
component of compensation affected to any significant degree by Corporation 
performance factors. The remaining component of his 1998 fiscal year 
compensation, however, was dependent upon performance and provided no dollar 
guarantees.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

         No member of the Compensation Committee is a former or current officer
or employee of the Corporation or any of its subsidiaries.

2. PROPOSED AMENDMENT OF THE CERTIFICATE OF INCORPORATION TO INCREASE 
                   AUTHORIZED SHARES OF COMMON STOCK

         The shareholders will consider and vote upon an amendment to 
Paragraph 4 of the Corporation's Certificate of Incorporation, as amended, to 
increase the number of authorized shares of Common Stock from 50,000,000 
shares to 75,000,000 shares (the "Common Stock Amendment").

         Pursuant to its Certificate of Incorporation, as amended, the 
Corporation is presently authorized to issue 50,000,000 shares of Common 
Stock and 5,000,000, shares of preferred stock, $.01 par value. On August 26, 
1998, if all of the shares of Common Stock currently reserved for issuance 
upon the exercise of outstanding warrants and options were issued, the number 
of shares of Common Stock that would be outstanding is 39,012,356 shares. The 
Company has also reserved an additional 2,250,000 shares of Common Stock for 
issuance upon the conversion of the D Stock and the E-1 Stock.

         On August 27, 1998, the Board of Directors approved an amendment to 
the Corporation's Certificate of Incorporation providing for an increase in 
the authorized shares of Common Stock from 50,000,000 shares to 75,000,000 
shares. The Board of Directors deems it to be in the best interest of the 
Corporation that the Corporation have available additional authorized shares 
of Common Stock for additional public offerings, acquisitions, financings, 
stock dividends, personnel recruitment and retention, and for other 
opportunities which may arise in the future. The additional shares of Common 
Stock would be available for issuance by action of the Board of Directors 
without the need for further action by shareholders, unless such action were 
specifically required by applicable law or rules of any stock exchange on 
which the Corporation's securities may then be listed. Under applicable laws 
of the State of New York, shareholders of the Corporation have no pre-emptive 
rights with respect to the authorization or issuance of additional shares of 
the Corporation's capital stock.

         The proposed increase in the authorized number of shares of Common 
Stock could have a number of effects on the Corporation's shareholders 
depending upon the exact nature and circumstances of any actual issuance of 
authorized but unissued shares. The increase could have an anti-takeover 
effect, in that additional shares could be issued (within the limits imposed 
by applicable law) in one or more transactions that could make a change in 
control or takeover of the Corporation more difficult. For example, 
additional shares could be issued by the Corporation so as to dilute the 
stock ownership or voting rights of persons seeking to obtain control of the 
Corporation. Similarly, the issuance of additional shares to certain persons 
allied with the Corporation's management could have the effect of making it 
more difficult to remove the Corporation's current management by diluting the 
stock ownership or voting rights of persons seeking to cause such removal.

         In addition, an issuance of additional shares by the Corporation 
could have an effect on the potential realizable value of a shareholder's 
investment. In the absence of a proportionate increase in the Corporation's 
earnings and book value, an increase in the aggregate number of outstanding 
shares of the Corporation caused by the issuance of the additional shares 
would dilute the earnings per share and book value per share of all 
outstanding shares of the Corporation's Common Stock. If such factors were 
reflected in the price per share of Common Stock, the potential realizable 
value of a shareholder's investment could be adversely affected.

VOTE REQUIRED FOR ADOPTION OF THE AMENDMENT

         Under New York law, the affirmative vote of the holders of 
securities representing a majority of the voting power entitled to vote at 
the Meeting is required to adopt the proposed Common Stock Amendment.

                  THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE ADOPTION 
OF THE COMMON STOCK AMENDMENT.

             3. RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

         The Board of Directors has selected the firm of Ernst & Young LLP to 
serve as the independent auditors for the Corporation for the fiscal year 
ending June 30, 1999. Representatives of Ernst & Young LLP are expected to be 
present at 


                                     12

<PAGE>

the Meeting, will have the opportunity to make a statement if they desire to 
do so, and will be available to respond to appropriate questions.

         Shareholder ratification of the appointment of Ernst & Young LLP as
