                       MAXIM PHARMACEUTICALS, INC.
                                    

  This Prospectus covers 3,375,000 shares (the "Shares") of the Common Stock, 
$.001 par value per share (the "Common Stock"), and 250,000 Underlying 
Warrants (defined below) of Maxim Pharmaceuticals, Inc., a Delaware 
corporation ("Maxim" or the "Company").  The Shares covered by this 
prospectus (the "Prospectus") are issuable by the Company upon exercise of: 
(i) 2,875,000 Redeemable Common Stock Purchase Warrants expiring July 10, 
2001 (the "Redeemable Warrants"), issued in connection with a public offering 
of units made by the Company on July 10, 1996 (the "Initial Public 
Offering"); (ii) warrants expiring July 10, 2001 (the "Representative's 
Warrants") to purchase 250,000 shares of Common Stock and 250,000 redeemable 
warrants (the "Underlying Warrants"), issued to the representative of the 
underwriters of the Initial Public Offering and (iii) the 250,000 Underlying 
Warrants.  The Underlying Warrants covered by this Prospectus are issuable 
upon exercise of the Representative's Warrants.  The Redeemable Warrants, 
Representative's Warrants and Underlying Warrants are sometimes hereinafter 
collectively referred to as the "Warrants."  The Warrants and the Shares are 
sometimes hereinafter collectively referred to as the "Securities."  Each 
Redeemable Warrant entitles the registered holder thereof to purchase one 
share of Common Stock at an initial exercise price of $10.50 per share at any 
time prior to July 10, 2001.  Each Representative Warrant entitles the 
registered holder thereof to purchase one share of Common Stock at a price of 
$9.00 per share and one Underlying Warrant at a price of $0.12 per Underlying 
Warrant at any time prior to July 10, 2001.  Each Underlying Warrant entitles 
the registered holder thereof to purchase one share of Common Stock at an 
initial exercise price of $12.38 per share at any time prior to July 10, 
2001.  The number of shares of Common Stock issuable upon exercise of the 
Warrants, and the respective exercise price therefore, are subject to 
adjustment under certain circumstances.  The number of Underlying Warrants 
issuable upon exercise of the Representative's Warrants and the exercise 
price therefore are also subject to adjustment under certain circumstances.  
The Company may redeem the Redeemable Warrants and the Underlying Warrants at 
$.01 per Redeemable Warrant and Underlying Warrant, respectively, on thirty 
(30) days' prior written notice to the registered holders thereof if the 
average closing bid price of the Common Stock as reported on the American 
Stock Exchange ("AMEX") equals or exceeds $12.00 per share for any twenty 
(20) trading days within a period of thirty (30) consecutive trading days 
ending on the fifth trading day prior to the date of the notice of 
redemption.  This prospectus relates only to shares of Common Stock and the 
Underlying Warrants, and neither the Redeemable Warrants, Representative's 
Warrants nor any other security is being offered hereby.  No underwriting 
discounts or commissions will be paid in connection with the exercise of the 
Warrants.
  
  No public market exists for the Representative's Warrants or the Underlying 
Warrants.  The Common Stock of the Company is traded on the American Stock 
Exchange ("AMEX") under the symbol "MMP" and the Stockholm Stock Exchange 
("SSE") under the symbol "MAXM."  The Redeemable Warrants are traded on the

  EXCEPT FOR THE HISTORICAL INFORMATION CONTAINED HEREIN OR INCORPORATED BY 
REFERENCE, THIS PROSPECTUS (AND THE INFORMATION INCORPORATED HEREIN BY 
REFERENCE) CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE CERTAIN RISKS AND 
UNCERTAINTIES.  THE COMPANY'S ACTUAL RESULTS COULD DIFFER MATERIALLY FROM 
THOSE DISCUSSED HEREIN OR INCORPORATED BY REFERENCE.  FACTORS THAT COULD

THOSE DISCUSSED IN THE FOLLOWING SECTION, THOSE DISCUSSED ELSEWHERE IN THIS 
PROSPECTUS, INCLUDING THE SECTION HEREIN ENTITLED "RISK FACTORS," AND THOSE 
DISCUSSED IN ANY OTHER DOCUMENTS INCORPORATED HEREIN BY REFERENCE.  

     Maxim Pharmaceuticals, Inc. ("Maxim" or the "Company") is developing 
novel therapeutics for the treatment of cancer and infectious disease.  The 
Company's lead drug, MAXAMINE,-TM-is designed to offer a safer treatment that 
extends life for seriously ill patients while maintaining quality of life 
during treatment. In many patients with cancer and chronic infectious 
diseases, the capacity of the patient's immune system to detect and destroy 
tumor cells or virally infected cells is compromised.  MAXAMINE THERAPY 
combines the administration of MAXAMINE, which protects critical immune 
cells, with the administration of certain agents, which stimulate these 
immune cells (these agents include cytokines and other biological response 
modifiers).  This combination of actions is designed to allow MAXAMINE 
THERAPY to improve the immune system's ability to identify, disable and 
destroy malignant or infected cells.  The Company believes that MAXAMINE
THERAPY has the potential to:  extend life; reduce toxic side effects of 
cytokines and other biological response modifiers; maintain the patient's 
quality of life during therapy; allow for self-administration at home; and 
provide cost-effective therapy.
     
     The Company has initiated three Phase III clinical trials of MAXAMINE 
THERAPY for the treatment of cancer.  In June 1997 the Company commenced a 
200-patient Phase III clinical trial of MAXAMINE THERAPY for advanced 
malignant melanoma in the United States.  A separate international Phase III 
advanced malignant melanoma trial centered in Sweden and Australia commenced 
in November 1997.  In February 1998 the Company initiated a Phase III 
clinical trial for acute myelogenous leukemia ("AML") in the United States, 
Europe and Australia.  Furthermore, the Company has initiated earlier stage 
clinical trials of MAXAMINE THERAPY for the treatment of renal cell 
carcinoma, hepatitis C, and multiple myeloma, and plans to evaluate the 
commencement of clinical trials of MAXAMINE THERAPY for the treatment of 
additional cancers, such as prostate adenocarcinoma, during 1998.  All 
studies of MAXAMINE THERAPY conducted to date have used MAXAMINE in 
combination with one or both of the cytokines interleukin-2 ("IL-2") and 
interferon-alpha ("IFN- "). Both IL-2 and IFN-  are cytokines with the 
capacity for stimulating certain immune functions.
     
     In the Company's two completed Phase II clinical trials for the 
treatment of advanced malignant melanoma, MAXAMINE THERAPY produced improved 
patient survival outcomes.  Median survival time for patients treated with 
MAXAMINE THERAPY in these two studies exceeded 13 and 15 months, 
respectively, as compared with reported median survival times of 
approximately seven months for existing available treatments.  In patients 
where the melanoma metastasized to the liver, MAXAMINE THERAPY improved 
median survival time to 19 months compared to predicted survival times of 
approximately four months or less for these patients.
     
     The Company's Phase II clinical trials for the treatment of AML have 
demonstrated an improvement of disease-free remission intervals.  As of 
February 1998, after 24 months of follow-up, 70% of patients treated with 
MAXAMINE THERAPY during their first complete remission ("CR1") remain in 
complete remission; less than 30% would be expected to remain in remission 
under current treatments.  Patients who relapsed and achieved a second or 
greater remission ("CR2+") and were subsequently treated with MAXAMINE 
THERAPY had a median time to relapse in excess of 21 months as compared with 
reported median time to relapse of approximately six months under the current 
standard of care.  Remission inversion (prolonging the duration of CR2+ to 
that equal to or exceeding the patient's prior remission duration) was 
achieved in 8 of 11 (73%) patients treated with MAXAMINE THERAPY as compared 
with approximately 10% to 20% under the current standard of care.
     
     Maxim is also developing MAXVAX-TM-, a mucosal vaccine carrier/adjuvant 
platform.  The MAXVAX technology is based on the B subunit of cholera toxin 
("CTB"), generally regarded as a safe and effective mucosal vaccine carrier. 
The Company expects that its future product development efforts will focus on 
mucosal vaccines against sexually transmitted diseases, major respiratory 
diseases and gastrointestinal tract diseases.  The MAXVAX

                                     4

<PAGE>


platform is also being evaluated for therapeutic vaccines and gene-based 
vaccines. The Company intends to seek collaborations with pharmaceutical and 
biopharmaceutical partners for the development of mucosal vaccine candidates.
     
     Maxim's drug development strategy is designed to facilitate product 
development from preclinical to FDA and other regulatory approvals and 
product launch.  Maxim plans to work with numerous collaborators, both 
pharmaceutical and clinical, in the oncology and infectious disease 
communities to extend the labeling of the drug to other indications.  In 
February 1998 Maxim entered into an agreement with Amgen Inc. under which 
Maxim will test MAXAMINE in combination with Amgen's Infergen-Registered 
Trademark-, interferon alfacon-1, in a planned clinical trial.  Also that 
month, Maxim entered into an agreement with a manufacturer and marketer of an 
IL-2 product under which that company will provide the IL-2 requirements for 
Maxim's Phase III AML clinical trial.  To market its products, the Company 
intends to develop marketing alliances with corporate partners and may 
co-promote and/or co-market in certain territories.
     
     The Company's principal executive offices are located at 8899 University 
Center Lane, Suite 200, San Diego, California 92122 and its telephone number

                               RISK FACTORS
                                
     AN INVESTMENT IN THE SHARES COVERED BY THIS PROSPECTUS
INVOLVES A HIGH DEGREE OF RISK.  PROSPECTIVE INVESTORS SHOULD
CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS, IN ADDITION TO OTHER
INFORMATION CONTAINED IN THIS PROSPECTUS AND IN ANY OTHER DOCUMENTS
INCORPORATED HEREIN BY REFERENCE IN EVALUATING AN INVESTMENT IN THE
SHARES OF COMMON STOCK COVERED BY THIS PROSPECTUS.

     DEVELOPMENT STAGE COMPANY; ACCUMULATED DEFICIT; UNCERTAINTY OF FUTURE 
PROFITABILITY.  The Company, as a development stage enterprise, has 
experienced net losses every year since its inception and, as of December 31, 
1997, had a deficit accumulated during the development stage of approximately 
$24 million.  The Company anticipates incurring substantial additional losses 
over at least the next several years due to, among other factors, the need to 
expend substantial amounts on its ongoing and planned clinical trials and 
anticipated research and development activities, and the business 
development, marketing and general and administrative expenses associated 
with those activities.  The Company has not commercially introduced any 
product and its products are in varying stages of development and testing.  
The Company's ability to attain profitability will depend upon its ability to 
develop products that are effective and commercially viable, to obtain 
regulatory approval for the manufacture and sale of its products and to 
market its products successfully.  There can be no assurance that the Company 
will ever achieve profitability or that profitability, if achieved, can be 
sustained on an ongoing basis.  

     NO ASSURANCE OF SUCCESSFUL CLINICAL TRIALS AND PRODUCT DEVELOPMENT.  All 
drug products currently under development by the Company will require 
extensive preclinical and clinical testing prior to regulatory approval for 
commercial use.  To date, the Company has not completed testing for efficacy 
or safety in humans on any of its products.  Substantial additional research 
and development will be necessary in order for the Company to develop 
products based on the Company's MAXAMINE and MAXVAX technologies and there 
can be no assurance that the Company's research and development efforts will 
lead to development of products that are shown to be safe and effective in 
clinical trials and are commercially viable.  In addition to further research 
and development, potential products based on the Company's MAXAMINE and 
MAXVAX technologies will require clinical testing, regulatory approval and 
substantial additional investment prior to commercialization.  There can be 
no assurance that any such products will be successfully developed, prove to 
be safe and effective in clinical trials, meet applicable regulatory 
standards, be capable of being produced in commercial quantities at 
acceptable costs, be eligible for third party reimbursement from governmental 
or private insurers, be successfully marketed or achieve market acceptance.  
Further, the Company's products may prove to have undesirable or unintended 
side effects that may prevent or limit their commercial use.  The Company may 
find, at any stage of this process, that products that appeared promising in 
preclinical studies or Phase I and Phase II clinical trials do not 
demonstrate efficacy in larger-scale, Phase III clinical trials and do not 
receive regulatory approvals.  Accordingly, any product development program 
undertaken by the Company may be curtailed, redirected or eliminated at any 
time.  In addition, there may be delays in the Company's testing and 
development schedules, and there can be no assurance that the Company will 
meet expected testing and development schedules, which could have a material 
adverse effect no the Company's business, financial condition and results of 
operations.  

     NO ASSURANCE OF REGULATORY APPROVAL; GOVERNMENT REGULATION. The U.S. 
Food and Drug Administration (the "FDA") and comparable agencies in countries 
outside the United States impose substantial requirements on the introduction 
of therapeutic pharmaceutical products and vaccines through lengthy and 
detailed laboratory and clinical testing procedures and other costly and time 
consuming procedures.  Satisfaction of these requirements typically takes a 
number of years and varies substantially based upon the type, complexity and 
novelty of the pharmaceutical agent.  In general, the FDA approval process 
for pharmaceuticals involves the submission of an Investigational New Drug 
("IND") application following preclinical studies, clinical trials in humans 
to demonstrate the safety and efficacy of the product under the protocols set 
forth in the IND and submission of preclinical and clinical data as well as 
other information to the FDA in a New Drug Application ("NDA") or Product 
License Application ("PLA").  The Company must expend substantial time and 
financial resources to conduct clinical trials.  The Company's early clinical 
trials were conducted overseas, and ongoing and future clinical trials will 
be conducted at least in part overseas.  There can be no assurance that the 
results of such trials will support the submission or the approval of an NDA 
or PLA or that data from the Company's overseas trials or 


                                     6

<PAGE>

approvals of the Company's products in foreign countries outside of the 
United States, if any, will be accepted by the FDA. Accordingly, there can be 
no assurance that FDA or other regulatory approval for any products developed 
by the Company will be granted on a timely basis, or at all.  There can be no 
assurance that the Company will have sufficient resources to complete the 
required regulatory review process, or that the Company could overcome the 
inability to obtain, or delays in obtaining, such approvals.  The failure of 
the Company to receive FDA approval for its products under development would 
preclude the Company from marketing and selling its products in the United 
States.  Therefore, failure to receive such FDA approval would have a 
material adverse effect on the business, financial condition and results of 
operations of the Company.  European and other international regulatory 
approvals are subject to the same risks and uncertainties as FDA and other 
regulatory approvals in the United States.

     The production and marketing of the Company's proposed
products, as well as its ongoing research and development
activities, are also subject to regulation by governmental agencies
of the United States and other countries. The effect of government
regulation may be to delay marketing of the Company's products for
a considerable period of time, to impose costly procedures upon the
Company's activities and to furnish a competitive advantage to
larger companies that compete with the Company.  Any delay in
obtaining, or failure to obtain, FDA or other necessary regulatory
approvals, including approvals by comparable agencies outside the
U.S., would adversely affect the marketing of the Company's
products and the ability to generate product revenue.  In addition,
the marketing and manufacturing of pharmaceuticals are subject to
continuing FDA (or comparable international agency) review and
surveillance and failure to comply with regulations or discovery of
previously unknown problems can result in FDA (or comparable
international agency) action against the product or the
manufacturer, including fines, recalls, product seizures and
suspension or withdrawal of previously granted regulatory
approvals. Furthermore, government regulation may increase at any
time, creating additional costs and delays for the Company.  The
extent of potential adverse government regulation which might arise
from future legislation or administrative action cannot be
predicted.  

     UNCERTAINTY REGARDING PATENTS AND PROPRIETARY RIGHTS.  It is the policy 
of the Company to file patent applications in the United States, Europe and 
other major markets throughout the world.  The patent positions of 
biotechnology and pharmaceutical companies are highly uncertain and involve 
complex legal and factual questions, and the breadth of claims allowed in 
biotechnology and pharmaceutical patents cannot be predicted.  There can be 
no assurance that patents will issue from any of the Company's patent 
applications.  With respect to already issued patents and any patents which 
may issue from the Company's applications, there can be no assurance that 
claims allowed will be sufficient to protect the Company's technologies.  
Patent applications in the United States are maintained in secrecy until a 
patent issues, and the Company cannot be certain that others have not filed 
patent applications for technology covered by the Company's pending 
applications or that the Company was the first to file patent applications 
for such technology.  Competitors may have filed applications for, or may 
have received patents and may obtain additional patents and proprietary 
rights relating to, compounds or processes that block or compete without 
infringing on those of the Company.  In addition, there can be no assurance 
that any patents issued to the Company or to licensors from whom the Company 
has licensed rights to its technologies will not be challenged, invalidated 
or circumvented or that the rights granted thereunder will provide 
proprietary protection or commercial advantage to the Company.

     Other public and private concerns, including universities, may have 
filed applications for or have been issued patents with respect to technology 
potentially useful or necessary to the Company.  The scope and validity of 
such patents, the extent to which the Company may wish or need to acquire 
licenses under such patents, and the cost or availability of such licenses, 
are currently unknown.

     In addition to patents and proprietary rights, the Company relies on 
unpatented trade secrets and proprietary know-how, and there can be no 
assurance that others will not obtain access to or independently develop such 
trade secrets and know-how.  Although potential corporate partners and the 
Company's research partners and consultants are not given access to trade 
secrets and proprietary know-how of the Company they have executed 
confidentiality agreements, these agreements may be breached by the other 
party thereto or may otherwise be of limited effectiveness or enforceability.


                                     7

     The pharmaceutical industry has experienced extensive litigation 
regarding patent and other intellectual property rights. Accordingly, the 
Company could incur substantial costs in defending itself in suits that may 
be brought against the Company claiming infringement of the patent rights of 
others or in asserting the Company's patent rights in a suit against another 
party.  The Company may also be required to participate in interference 
proceedings declared by the United States Patent and Trademark Office for the 
purpose of determining the priority of inventions in connection with the 
patent applications of the Company or other parties.  Adverse determinations 
in litigation or interference proceedings could require the Company to seek 
licenses (which may not be available on commercially reasonable terms) or 
subject the Company to significant liabilities to third parties, and could 
therefore have a material adverse effect on the Company.

     In 1993 and 1994 the Company entered into agreements under which the 
Company received exclusive, worldwide rights to certain technologies related 
to the MaxVax technology.  In January 1998 the Company filed a complaint in 
the United States District Court for the Southern District of California 
relating to the licensors' performance under the agreements.  The complaint 
alleges certain causes of action against the licensors and seeks compensatory 
and punitive damages and declaratory relief.  The complaint also seeks 
specific performance of the licensors' obligations under the agreements.  The 
Company has filed a request for arbitration in connection with the issues 
presented by the complaint.  The Company cannot determine what impact, if 
any, an unfavorable resolution of the existing concerns would have on the 
commercial value of the MaxVax technology. 

     NEED FOR ADDITIONAL FUNDS; UNCERTAINTY OF ADDITIONAL FUNDING. The 
Company's operations to date have consumed substantial amounts of cash. 
Negative cash flow from the Company's operations is expected to continue and 
to accelerate over at least the next several years.  The Company's capital 
requirements will depend on numerous factors, including: the progress of 
preclinical testing and clinical trials; the progress of the Company's 
research and development programs; the time and costs required to obtain 
regulatory approvals; the resources devoted to manufacturing methods and 
advanced technologies; the timing and amount, if any, of funding obtained 
through corporate collaborations; the cost of filing, prosecuting and, if 
necessary, enforcing patent claims; the cost of commercialization activities 
and arrangements; and the demand for the Company's products if and when 
approved. The Company may have to raise substantial additional funds to 
complete development of any product or bring products to market.  Issuance of 
additional equity securities by the Company, for these or other purposes, 
could result in dilution to then existing stockholders. There can be no 
assurance that additional financing will be available on acceptable terms, if 
at all.  If adequate funds are not available on acceptable terms, 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 or products that the Company would not otherwise 
relinquish, which may have a material adverse effect on the Company's 
business, financial condition and results of operations. 

     DEPENDENCE ON QUALIFIED PERSONNEL.  The Company's future
performance depends in part upon the continued contributions of its
senior management and on the ability to attract and retain
qualified management and scientific personnel.  Competition for
such personnel is intense, and there can be no assurance that the
Company will be able to continue to attract, assimilate or retain
highly qualified technical and management personnel.  The loss of
key personnel or the failure to recruit additional personnel or to
develop needed expertise could have a material adverse effect on
the Company's business, financial condition and results of
operations.  

     DEPENDENCE ON COLLABORATIVE PARTNERS.  The Company's strategy for the 
research, development, clinical testing, manufacturing and commercialization 
of certain of its products requires arrangements with corporate and 
university collaborators, licensors, marketing partners, licensees, 
consultants and others, and is dependent upon the subsequent success of these 
outside parties in performing their responsibilities.  Although the Company 
believes parties to any such existing or future arrangements will or would 
have an economic motivation to perform their contractual responsibilities, 
the amount and timing of resources to be devoted to these activities may not 
be within the control of the Company.  In addition, there can be no assurance 
that collaborators will not pursue alternative technologies as a means for 
developing treatments for the diseases targeted by these collaborative 
programs.  Furthermore, there can be no assurance that the Company will be 
able to negotiate acceptable collaborative arrangements, or that its 
collaborative arrangements will be successful.  


                                     8


<PAGE>

     NO MARKETING AND SALES CAPABILITIES; ANTICIPATED DEPENDENCE UPON 
MARKETING ALLIANCES.  The Company has not developed pharmaceutical marketing 
or sales capabilities.  In order to market and sell certain products, the 
Company will need to develop a sales force and a marketing group with 
technical expertise, or make appropriate arrangements with strategic 
partners.  There can be no assurance that the Company will be able to gain 
such expertise or that such efforts will be successful.  The Company's 
strategy for development, commercialization and marketing of MAXAMINE and 
MAXVAX is expected to involve, where appropriate, the establishment of 
marketing and other collaborative relationships with pharmaceutical industry 
partners.  There can be no assurance that any such relationships can be 
consummated on terms favorable to the Company or that marketing efforts 
undertaken by such partners will be successful.  

     NO ASSURANCE OF MARKET ACCEPTANCE.  There can be no assurance that, if 
approved for marketing, MAXAMINE or any of the Company's other products in 
development will achieve market acceptance.  The degree of market acceptance 
will depend upon a number of factors, including the scope of regulatory 
approvals, the establishment and demonstration in the medical community of 
the clinical efficacy and safety of the Company's products and therapies and 
their potential advantages over existing treatment methods, and reimbursement 
policies of government and third-party payors.  There can be no assurance 
that physicians, patients, payors or the medical community in general will 
accept and utilize any products that may be developed by the Company.  

     NO MANUFACTURING CAPABILITIES.  The Company has not invested in the 
development of internal pharmaceutical manufacturing capabilities.  The 
Company's strategy has been, and is expected to continue to be for the 
foreseeable future, to contract with established pharmaceutical manufacturers 
for the production of MAXAMINE.  If the Company is unable to contract for 
manufacturing capabilities on acceptable terms, the Company's ability to 
conduct clinical testing and to produce commercial quantities of product will 
be adversely affected, resulting in delays in submissions for regulatory 
approval and in commercial product launches, which in turn could materially 
impair the Company's competitive position and the possibility of achieving 
profitability. There can be no assurance that the Company will be able to 
maintain its existing, or acquire or establish new, satisfactory third-party 
relationships to provide manufacturing resources.  

     COMPETITION.  There are many companies, both publicly and privately 
held, including well-known pharmaceutical companies, as well as academic and 
other research institutions, engaged in developing pharmaceutical and 
biologically-derived products for the treatment of cancer and vaccines and 
therapeutics for the prevention or the treatment of infectious diseases.  
Many of the Company's competitors and potential competitors have 
substantially greater capital, research and development capabilities and 
human resources than the Company and represent significant competition for 
the Company.  Many of these competitors have significantly greater experience 
than the Company in undertaking preclinical testing and clinical trials of 
new pharmaceutical products and obtaining FDA and other regulatory approvals. 
If the Company is permitted to commence commercial sales of any product, it 
will also be competing with companies that have greater resources and 
experience in the manufacturing, marketing and sales of pharmaceutical 
products.  The Company's competitors may succeed in developing products that 
are more effective, less costly, or have a better side effect profile than 
any that may be developed by the Company, and such competitors may also prove 
to be more successful than the Company in manufacturing, marketing and sales. 

     TECHNOLOGICAL CHANGES AND UNCERTAINTY.  The Company is engaged in the 
pharmaceutical field, which is characterized by extensive research efforts 
and rapid technological progress.  New developments in oncology, cancer 
therapy, medicinal pharmacology, biochemistry and other fields are expected 
to continue at a rapid pace in both industry and academia.  There can be no 
assurance that research and discoveries by others will not render some or all 
of the Company's proposed programs or products noncompetitive or obsolete.  
The Company's business strategy is subject to the risks inherent in the 
development of new products using new technologies and approaches.  There can 
be no assurance that unforeseen problems will not develop with these 
technologies or applications, that the Company will be able to address 
successfully technological challenges it encounters in its research and 
development programs or that commercially feasible products will ultimately 
be developed by the Company.  

     LEGAL PROCEEDINGS.  In March 1997, the former President and Chief 
Operating Officer and the Chief Financial Officer of the Company (the "Former 
Employees") filed a complaint in the Superior Court in the State of 


                                     9

<PAGE>

California, County of San Diego (the "Complaint") seeking claims for certain 
purported damages in contract and in tort arising from their respective 
terminations of employment with the Company in March 1996.  In addition, the 
Former Employees asserted possible punitive damages and damages based on 
emotional distress. The Former Employees also claimed the right to vested 
options of the Company's Common Stock.  According to the Complaint, each of 
the Former Employees appears to be claiming compensatory damages in excess of 
$2 million and punitive damages in excess of $3 million.  In June 1997, the 
Company filed an answer to the Complaint denying each of the allegations 
therein and, in March 1998, filed a motion for summary judgment, which is 
scheduled to be heard by the Court in April 1998.  Pretrial discovery with 
respect to these legal proceedings has commenced, and a trial date has been 
scheduled for May 1998.  The Company believes the Former Employees' claims 
are without merit and the Company intends to contest any such claims 
vigorously. However, there can be no assurances as to the eventual outcome of 
such claims or their effect on the Company's business, financial condition 
and results of operations.  In addition, an adverse determination in any 
litigation arising from these claims or the settlement of such claims could 
have a material adverse effect on the Company's business, financial condition 
and results of operations.  

     ABSENCE OF DIVIDENDS.  The Company has never declared or paid dividends 
on its Common Stock and does not anticipate paying any dividends in the 
foreseeable future.  In addition, the Company has entered into a Loan and 
Security Agreement with Silicon Valley Bank which restricts the payment of 
dividends by the Company.

     PRODUCT LIABILITY EXPOSURE AND INSURANCE.  The Company's business 
exposes it to potential product liability risks which are inherent in the 
clinical testing, manufacturing and marketing of human therapeutic products.  
The Company currently maintains liability insurance coverage for its clinical 
trials, and intends to expand its insurance coverage to include the sales of 
commercial products if marketing approval is obtained for MAXAMINE or other 
products in development.  There can be no assurance that such coverage is or 
in the future will be adequate or that adequate insurance will be available 
in the future at an acceptable cost, if at all.  In addition, there can be no 
assurance that a product liability claim, even if the Company has insurance 
coverage, would not materially adversely affect the business or financial 
condition of the Company.

     POTENTIAL ADVERSE EFFECT OF SHARES ELIGIBLE FOR FUTURE SALE; PRICE 
VOLATILITY OF THE COMMON STOCK.  Sales of substantial amounts of the Common 
Stock of the Company in the public market could adversely affect prevailing 
market prices for the Common Stock and the ability of the Company to raise 
equity capital in the future. The Company's Common Stock currently trades on 
the AMEX and on the SSE.  Historically, the Common Stock has generally 
experienced relatively low daily trading volumes in relation to the aggregate 
number of shares outstanding.  The price and liquidity of the Common Stock 
may be significantly affected by trading activity and market factors related 
to the AMEX and SSE, which factors and the effects thereof may differ between 
these markets.  In addition, the securities markets have from time to time 
experienced significant price and volume fluctuations that may be unrelated 
to the operating performance of particular companies.  In addition, the 
market prices of the common stock of many publicly traded pharmaceutical or 
biotechnology companies have in the past been, and can in the future be 
expected to be, especially volatile.  Low trading volumes, announcements of 
technological innovations or new products by the Company or its competitors, 
developments or disputes concerning patents or proprietary rights, publicity 
regarding actual or potential medical results relating to products under 
development by the Company or its competitors, regulatory developments in 
both the United States and countries outside of the United States, delays in 
the Company's testing and development schedules, events or announcements 
relating to the Company's collaborative relationships with others, public 
concern as to the safety of biopharmaceutical or biotechnology products and 
economic and other external factors, as well as period-to-period fluctuations 
in the Company's financial results, may have a significant impact on the 
market price or liquidity of the Common Stock.

     DISCRETION OF MANAGEMENT AND THE BOARD OF DIRECTORS IN USE OF PROCEEDS.  
Although the Company currently intends to apply the net proceeds, if any, 
from the sale of Securities in the manner described under "Use of Proceeds," 
the Company's management and the Board of Directors have broad discretion 
within such proposed uses as to the precise allocation of the net proceeds, 
the timing of expenditures and all other aspects of the use thereof.  The 
Company reserves the right to reallocate the net proceeds, if any, from the 
sale of Securities among the various categories set forth under "Use of 
Proceeds" as it, in its sole discretion, deems necessary or advisable based 
upon prevailing business conditions and circumstances.  See "Use of Proceeds."

     NO PUBLIC MARKET FOR UNDERLYING WARRANTS.  No public market exists for 
the Underlying Warrants, nor does the Company expect one to develop.  
Although the Underlying Warrants, when issued, will be freely tradable, 
holders thereof may not be able to sell the Underlying Warrants at desirable 
prices, if at all.

     POTENTIAL ADVERSE EFFECT OF REDEMPTION OF UNDERLYING WARRANTS.  The 
Underling Warrants are subject to redemption at $0.01 per warrant on thirty 
days' prior written notice to the holders thereof if the average closing bid 
price of the Common Stock equals or exceeds $12.00 per Share of Common Stock 
for any 20 trading days within a period of 30 consecutive trading days ending 
on the fifth trading day prior to the date of the notice of redemption.  If 
the Underlying Warrants are redeemed, holders thereof will lose their rights 
to exercise the Underlying Warrants after the expiration of the 30-day notice 
of redemption period.  Upon receipt of a notice of redemption, holders would 
be required to:  (i) exercise the Underlying Warrants and pay the exercise 
price at a time when it may be disadvantageous for them to do so, (ii) sell 
the Underlying Warrants at the current market price, if any, when they might 
otherwise wish to hold the Underlying Warrants or (iii) accept the redemption 
price which is likely to be substantially less than the market value of the 
Underlying Warrants at the time of redemption. See "Description of Securities 
Underlying Warrants."

<PAGE>

                        USE OF PROCEEDS

     The Shares and Underlying Warrants covered by this Prospectus may be 
purchased at any time prior to July 10, 2001.  Holders of the Warrants will 
be able to determine, in their sole discretion, when and if any of the Shares 
or Underlying Warrants covered by this Prospectus will be sold, if at all.  
Accordingly, there can be no assurance that the Company will receive any 
proceeds from the sale of the Securities covered by this Prospectus.

     In the event that all of the Securities covered hereby are sold, the net 
proceeds to the Company will be approximately $35.5 million, after deducting 
offering expenses payable by the Company.

     The Company intends to use the majority of the net proceeds, if any, 
from the sale of Securities to fund its research and development efforts, 
including preclinical and clinical studies, and to prepare for the commercial 
launch of MAXAMINE.  The cost, timing and amount of funds required for such 
uses by the Company is not precisely determined.  However, the Company 
anticipates that approximately one-half of the funds will be used to advance 
the Company's MAXAMINE technology, including the conduct of the current Phase 
III clinical studies and other ongoing or planned clinical studies, and 
approximately one-half will be used to prepare for the commercial launch of 
MAXAMINE, including the initial marketing efforts associated with such a 
launch.  The remainder, if any, of the net proceeds will be used for working 
capital and general corporate purposes.  These amounts are estimates, and the 
amount and timing of the expenditures of the net proceeds for these purposes 
will depend on numerous factors, including the status of the Company's 
product development efforts, the results of clinical trials, the regulatory 
approval process, competition, manufacturing activities and market acceptance 
of the Company's products, and the extent to which the Company relies upon 
corporate collaborations for the marketing of its products.  The Company may 
also use a portion of the net proceeds to acquire complementary businesses, 
products or technologies, although the Company has no agreements and is not 
involved in any negotiations with respect to any such transactions. Pending 
such uses, the Company plans to invest the net proceeds, if any, from the 
sale of Securities in short-term, investment-grade, interest-bearing 
securities.

                                   DILUTION

     The net tangible book value of the Company's Common Stock as of December 
31, 1997 was approximately $43.3 million, or $4.70 per share.  Net tangible 
book value per share represents the total amount of tangible assets less 
total liabilities divided by the number of shares of Common Stock issued.  
After giving effect to the sale of the 3,375,000 shares of Common Stock 
offered hereby and the receipt of the estimated net proceeds (after deducting 
the estimated offering expenses payable by the Company), the net tangible 
book value of the Company at December 31, 1997 would have been approximately 
$79.7 million or $6.33 per share.  This represents an immediate increase in 
net tangible book value of $1.63 per share to existing stockholders and an 
immediate dilution in net tangible book value of $4.17 per share to 
purchasers of shares of Common Stock issuable upon exercise of the Redeemable 
Warrants, based on the exercise price of the Redeemable Warrants. Purchasers 
of shares of Common Stock upon exercise of the Representative's Warrants and 
the Underlying Warrants would realize immediate dilution of $2.67 and $6.05 
per share, respectively.  The following table illustrates the per share 
dilution realized by purchasers of shares of Common Stock issuable upon 
exercise of the Redeemable Warrants:

                             PLAN OF DISTRIBUTION

     On July 16, 1996, the Company closed the Initial Public Offering, in 
which it sold units consisting of one share of Common Stock and one 
Redeemable Warrant.  Each Redeemable Warrant entitles the registered holder 
thereof to purchase one share of Common Stock at an initial exercise price of 
$10.50 per share at any time prior to July 10, 2001.  In connection with the 
Initial Public Offering, the Company issued the Representative's Warrants to 
the representative of the underwriters for the Initial Public Offering as 
part of its compensation for acting as such.  Each Representative Warrant 
entitles the registered holder thereof to purchase one share of Common Stock 
at a price of $9.00 per share and one Underlying Warrant at a price of $0.12 
per Underlying Warrant at any time prior to July 10, 2001.  Each Underlying 
Warrant entitles the registered holder thereof to purchase one share of 
Common Stock at an initial exercise price of $12.38 per share at any time 
prior to July 10, 2001.

     The 3,375,000 shares of Common Stock covered by this Prospectus are the 
shares issuable upon exercise of the 2,875,000 Redeemable Warrants, 250,000 
Representative's Warrants and 250,000 Underlying Warrants.  The 250,000 
Underlying Warrants covered by this Prospectus are issuable upon exercise of 
the Representative's Warrants.

     The Company may redeem the Redeemable Warrants and the Underlying 
Warrants at $.01 per Redeemable Warrant and Underlying Warrant, respectively, 
on thirty (30) days' prior written notice to the registered holders thereof 
if the average closing bid price of the Common Stock as reported on the AMEX 
equals or exceeds $12.00 per share for any twenty (20) trading days within a 
period of thirty (30) consecutive trading days ending on the fifth trading 
day prior to the date of the notice of redemption.

     No public market exists for the Representative's Warrants or the 
Underlying Warrants.  The Common Stock of the Company is traded on the AMEX 
under the symbol "MMP" and on the SSE under the symbol "MAXM."  The 
Redeemable Warrants are traded on the AMEX under the symbol "MMP/WS."  The 
last sales price of the Company's Common Stock as reported by the AMEX on 
March 13, 1998 was $15.50 per share.  The last sales price of the Redeemable 
Warrants as reported by the AMEX on March 13, 1998 was $5.75 per Redeemable 
Warrant.

                          DESCRIPTION OF SECURITIES

     The authorized capital stock of the Company consists of 20,000,000 
shares of Common Stock, $0.001 par value, and 5,000,000 shares of Preferred 
Stock, $0.001 par value (the "Preferred Stock").

Common Stock

     At December 31, 1997, 9,214,052 shares of Common Stock were outstanding 
and held of record by approximately 120 stockholders. The holders of Common 
Stock are entitled to one vote per share on all matters to be voted upon by 
the stockholders. Subject to preferences that may be applicable to any 
outstanding Preferred Stock, the holders of Common Stock are entitled to 
receive ratably such dividends, if any, as may be declared from time to time 
by the Board of Directors out of funds legally available therefor.  In the 
event of a liquidation, dissolution or winding up of the Company, the holders 
of Common Stock are entitled to share ratably in all assets remaining after 
payment of liabilities and the liquidation preferences of any outstanding 
shares of Preferred Stock. Holders of Common Stock have no preemptive, 
conversion, subscription or other rights. There are no redemption or sinking 
fund provisions available to the Common Stock. All outstanding shares of 
Common Stock are fully paid and non-assessable. The Common Stock is listed on 
AMEX under the symbol "MMP" and on the SSE under the symbol "MAXM." 

                                     13

<PAGE>

Preferred Stock

     The Board of Directors has the authority, without further action by the 
stockholders, to issue up to 5,000,000 shares of Preferred Stock in one or 
more series and to fix the rights, preferences, privileges and restrictions 
thereof, including dividend rights, conversion rights, voting rights, terms 
of redemption, liquidation preferences, sinking fund terms and the number of 
shares constituting any series or the designation of such series, any or all 
of which may be greater than the rights of the Common Stock. The issuance of 
Preferred Stock could adversely affect the voting power of holders of Common 
Stock and reduce the likelihood that such holders will receive dividend 
payments and payments upon liquidation and could have the effect of delaying, 
deterring or preventing a change in control of the Company. The Company has 
no present plan to issue any shares of Preferred Stock.

Redeemable Warrants

     As of December 31, 1997, there were outstanding Redeemable Warrants to 
purchase up to 2,875,000 shares of Common Stock.  The Redeemable Warrants are 
listed on AMEX under the trading symbol "MMP/WS."  The following is a brief 
summary of certain provisions of the Redeemable Warrants, but such summary 
does not purport to be complete and is qualified in all respects by reference 
to the actual text of that certain Warrant Agreement between the Company, 
National Securities Corporation (the "Representative") and American Stock 
Transfer & Trust Company (the "Warrant Agent").  A copy of the Warrant 
Agreement has been filed as an exhibit to the Registration Statement of which 
this Prospectus is a part.  See "Additional Information."

     EXERCISE PRICE AND TERMS.  The Redeemable Warrants expire on July 10, 
2001.  Each Warrant entitles the registered holder thereof to purchase, at 
any time prior to July 10, 2001, one share of Common Stock at a price of 
$10.50 per share, subject to adjustment in accordance with the anti-dilution 
and other provisions referred to below.  The holder of any Redeemable Warrant 
may exercise such Redeemable Warrant by surrendering the certificate 
representing the Redeemable Warrant to the Warrant Agent, with the 
subscription form thereon properly completed and executed, together with 
payment of the exercise price.  The Redeemable Warrants may be exercised at 
any time prior to July 10, 2001 in whole or in part at the applicable 
exercise price.  No fractional shares will be issued upon the exercise of the 
Redeemable Warrants.

     The exercise price of the Redeemable Warrants bears no relationship to 
any objective criteria of value and should in no event be regarded as an 
indication of any future market price of the Securities offered hereby.

     ADJUSTMENTS.  The exercise price and the number of shares of Common 
Stock purchasable upon the exercise of the Redeemable Warrants are subject to 
adjustment upon the occurrence of certain events, including stock dividends, 
stock splits, combinations or reclassifications of the Common Stock.  
Additionally, an adjustment would be made in the case of a reclassification 
or exchange of Common Stock, consolidation or merger of the Company with or 
into another corporation (other than a consolidation or merger in which the 
Company is the surviving corporation) or sale of all or substantially all of 
the assets of the Company in order to enable holders of Redeemable Warrants 
to acquire the kind and number of shares of stock or other securities or 
property receivable in such event by a holder of the number of shares of 
Common Stock that might otherwise have been purchased upon the exercise of 
the Redeemable Warrant.

     REDEMPTION PROVISIONS.  The Redeemable Warrants are subject to 
redemption at $.01 per Redeemable Warrant on thirty (30) days' prior written 
notice to the holders thereof if the average closing bid price of the Common 
Stock as reported on the AMEX equals or exceeds $12.00 per share of Common 
Stock for any twenty (20) trading days within a period of thirty (30) 
consecutive trading days ending on the fifth trading day prior to the date of 
the notice of redemption.  In the event the Company exercises the right to 
redeem the Redeemable Warrants, such Redeemable Warrants will be exercisable 
until the close of business on the business day immediately preceding the 
date for redemption fixed in such notice. If any Redeemable Warrant called 
for redemption is not exercised by such time, it will cease to be exercisable 
and the holder will be entitled only to the redemption price.

                                     14

<PAGE>

     TRANSFER, EXCHANGE AND EXERCISE.  The Redeemable Warrants are in 
registered form and may be presented to the Warrant Agent for transfer, 
exchange or exercise at any time on or prior to July 10, 2001, at which time 
the Redeemable Warrants become wholly void and of no value.  If a market for 
the Redeemable Warrants continues to exist, holders may sell the Redeemable 
Warrants instead of exercising them.  There can be no assurance, however, 
that a market for the Redeemable Warrants will continue.

     WARRANTHOLDER NOT A STOCKHOLDER.  The Redeemable Warrants do not confer 
upon holders thereof any voting, dividend or other rights as stockholders of 
the Company.

     MODIFICATION OF REDEEMABLE WARRANTS.  The Company and the Warrant Agent 
may make such modifications to the Redeemable Warrants as they deem necessary 
and desirable that do not adversely affect the interests of the holders 
thereof.  The Company may, in its sole discretion, lower the exercise price 
of the Redeemable Warrants for a period of not less than thirty (30) days on 
not less than thirty (30) days' prior written notice to the holders thereof 
and the Representative.  Modification of the number of securities purchasable 
upon the exercise of any Redeemable Warrant, the exercise price and the 
expiration date with respect to any Redeemable Warrant requires the consent 
of two-thirds of the holders thereof.  No other modifications may be made to 
the Redeemable Warrants without the consent of two-thirds of the 
warrantholders.

     The Redeemable Warrants are not exercisable unless, at the time of the 
exercise, the Company has a current prospectus covering the shares of Common 
Stock issuable upon exercise of the Redeemable Warrants, and such shares have 
been registered, qualified or deemed to be exempt under the securities laws 
of the state of residence of the exercising holder of the Redeemable 
Warrants.  Although the Company will use its best efforts to have all the 
shares of Common Stock issuable upon exercise of the Redeemable Warrants 
registered or qualified on or before the exercise date and to maintain a 
current prospectus relating thereto until the expiration of the Redeemable 
Warrants, there can be no assurance that it will be able to do so.

     The Redeemable Warrants are separately transferable. Purchasers may buy 
Redeemable Warrants in the aftermarket in, or may move to, jurisdictions in 
which the shares underlying the Redeemable Warrants are not so registered or 
qualified during the period that the Redeemable Warrants are exercisable.  In 
this event, the Company would be unable to issue shares to those persons 
desiring to exercise their Redeemable Warrants, and holders of Redeemable 
Warrants would have no choice but to attempt to sell the Redeemable Warrants 
in a jurisdiction where such sale is permissible or allow them to expire 
unexercised. 

REPRESENTATIVE'S WARRANTS

     Also, as of December 31, 1997, there were outstanding Representative's 
Warrants to purchase up to 250,000 shares of Common Stock and/or 250,000 
Underlying Warrants.  The Representative's Warrants are not traded on any 
exchange nor listed on any stock market.  Accordingly, no public market 
exists for the Representative's Warrants, and the Company does not expect one 
to develop.  The Representative's Warrants are exercisable at a price of 
$9.00 per share of Common Stock and $0.12 per Underlying Warrant until July 
10, 2001.  The Representative's Warrants provide for adjustment in the number 
of shares of Common Stock and Underlying Warrants issuable upon the exercise 
thereof and in the exercise price of the Representative's Warrants as a 
result of certain events, including subdivisions and combinations of the 
Common Stock.  The Representative's Warrants, and the securities underlying 
the Representative's Warrants, have been registered with the SEC and may be 
sold at any time, subject to certain requirements imposed by applicable 
securities laws.  The Representative's Warrants grant to the holders thereof 
certain rights of registration with respect to the securities issuable upon 
exercise thereof.

     TRANSFER, EXCHANGE AND EXERCISE; EXERCISE PRICE.  The holder of any 
Representative's Warrant may exercise such Representative's Warrant by 
surrendering the certificate representing the Representative's Warrant to the 
Secretary of the Company, with the subscription form thereon properly 
completed and executed, together with payment of the exercise price.  The 
Representative's Warrant may be exercised at any time prior to July 10, 2001 
in whole or in part at the applicable exercise price.  No fractional shares 
will be issued upon the exercise of the Representative's Warrants.  On July 
10, 2001, the Representative's Warrants become wholly void and of no value.

                                     15

<PAGE>

     The exercise price of the Representative's Warrants bears no 
relationship to any objective criteria of value and should in no event be 
regarded as an indication of any future market price of the Securities 
offered hereby.  

     WARRANTHOLDER NOT A STOCKHOLDER.  The Representative's Warrants do not 
confer upon holders thereof any voting, dividend or other rights as 
stockholders of the Company.

     The Representative's Warrants are not exercisable unless, at the time of 
the exercise, the Company has a current prospectus covering the shares of 
Common Stock and Underlying Warrants issuable upon exercise of the 
Representative's Warrants, and such shares and warrants have been registered, 
qualified or deemed to be exempt under the securities laws of the state of 
residence of the exercising holder of the Representative's Warrants.  
Although the Company will use its best efforts to have all the shares of 
Common Stock and all Underlying Warrants issuable upon exercise of the 
Representative's Warrants registered or qualified on or before the exercise 
date and to maintain a current prospectus relating thereto until the 
expiration of the Representative's Warrants, there can be no assurance that 
it will be able to do so.

     The Representative's Warrants are separately transferable. Purchasers 
may buy Representative's Warrants in, or may move to, jurisdictions in which 
the shares and warrants underlying the Representative's Warrants are not so 
registered or qualified during the period that the Representative's Warrants 
are exercisable.  In this event, the Company would be unable to issue shares 
or warrants to those persons desiring to exercise their Representative's 
Warrants, and holders of Representative's Warrants would have no choice but 
to attempt to sell the Representative's Warrants in a jurisdiction where such 
sale is permissible or allow them to expire unexercised.

UNDERLYING WARRANTS

     The Underlying Warrants, which are issuable upon exercise of the 
Representative's Warrants, are exercisable at a price of $12.38 per share of 
Common Stock until July 10, 2001.  The Underlying Warrants are not traded on 
any exchange nor listed on any stock market.  Accordingly, no public market 
exists for the Underlying Warrants, and the Company does not expect one to 
develop.  Although the Underlying Warrants, when issued, will be freely 
tradable, holders thereof may not be able to sell the Underlying Warrants at 
desirable prices, if at all.  Other than with respect to the exercise price 
thereof, and except as set forth below, the Underlying Warrants will contain 
provisions and be subject to terms and conditions that are substantially 
similar to the provisions, terms and conditions of the Redeemable Warrants, 
including provisions regarding redemption and adjustments.  See "Redeemable 
Warrants."  The actual provisions, terms and conditions of the Redeemable 
Warrants are set forth in that certain Representative's Warrant Agreement 
between the Company and the Representative, a copy of which has been filed as 
an exhibit to the Registration Statement of which this Prospectus is a part.  
See "Additional Information."

     TRANSFER, EXCHANGE AND EXERCISE; EXERCISE PRICE.  The holder of any 
Underlying Warrant may exercise such Underlying Warrant by surrendering the 
certificate representing the Underlying Warrant to the Secretary of the 
Company, with the subscription form thereon properly completed and executed, 
together with payment of the exercise price.  The Underlying Warrants may be 
exercised at any time prior to July 10, 2001 in whole or in part at the 
applicable exercise price.  No fractional shares will be issued upon the 
exercise of the Underlying Warrants.  On July 10, 2001, the Underlying 
Warrants become wholly void and of no value.

     The exercise price of the Underlying Warrants bears no relationship to 
any objective criteria of value and should in no event be regarded as an 
indication of any future market price of the Securities offered hereby.

     WARRANTHOLDER NOT A STOCKHOLDER.  The Underlying Warrants do not confer 
upon holders thereof any voting, dividend or other rights as stockholders of 
the Company.

     The Underlying Warrants are not exercisable unless, at the time of the 
exercise, the Company has a current prospectus covering the shares of Common 
Stock issuable upon exercise of the Underlying Warrants, and such shares have 
been registered, qualified or deemed to be exempt under the securities laws 
of the state of residence of the exercising holder of the Underlying 
Warrants.  Although the Company will use its best efforts to have all the

                                     16
<PAGE>

shares of Common Stock issuable upon exercise of the Underlying Warrants 
registered or qualified on or before the exercise date and to maintain a 
current prospectus relating thereto until the expiration of the Underlying 
Warrants, there can be no assurance that it will be able to do so.

     The Underlying Warrants are separately transferable. Purchasers may buy 
Underlying Warrants in, or may move to, jurisdictions in which the shares 
underlying the Underlying Warrants are not so registered or qualified during 
the period that the Underlying Warrants are exercisable.  In this event, the 
Company would be unable to issue shares to those persons desiring to exercise 
their Underlying Warrants, and holders of Underlying Warrants would have no 
choice but to attempt to sell the Underlying Warrants in a jurisdiction where 
such sale is permissible or allow them to expire unexercised.

OTHER WARRANTS

     As of December 31, 1997, there were outstanding warrants to purchase 
305,976 shares of Common Stock at an exercise price of $3.00 per share. Such 
warrants expire between one to four years from July 10, 1996, and most are 
currently exercisable. 

TRANSFER AGENT AND REGISTRAR

     The Transfer Agent and Registrar for the Common Stock and the Warrant 
Agent for the Redeemable Warrants is American Stock Transfer & Trust Company. 
 The Secretary of the Company is the warrant agent for the Representative's 
Warrants and the Underlying Warrants.

                                LEGAL MATTERS

     The validity of the issuance of the Common Stock and Underlying Warrants 
covered by this Prospectus will be passed upon for the Company by Cooley

ITEM 17.          UNDERTAKINGS.

   The undersigned Registrant hereby undertakes:
              
   (a) (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(a)(3) of the
Securities Act;
          
           (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 informationin the Registration Statement;

   PROVIDED, HOWEVER, that subparagraphs (i) and (ii) shall not apply if the 
information required to be included in a post-effective amendment by those 
subparagraphs is contained in periodic reports filed with or furnished to the 
Securities and Exchange Commission by the Registrant pursuant to Section 13 
or Section 15(d) of the Securities 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, 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 this offering.


                                     II-2
<PAGE>

     (b)  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 Act of 1934) that is incorporated by reference into 
this Registration Statement shall be deemed to be a new Registration 
Statement relating to the securities offered herein, and the offering of such 
securities at that time shall be deemed to be the initial bona fide offering 
thereof.
  
      (c) Insofar as indemnification by the Registrant for liabilities 
arising under the Securities Act may be permitted to directors, officers and 
controlling persons of the Registrant pursuant to the provisions referenced 
in Item 15 of this Registration Statement or otherwise, the Registrant has 
been advised that in the opinion of the Securities and Exchange Commission 
such indemnification is against public policy as expressed in the Securities 
Act, and is, therefore, unenforceable. In the event that a claim for 
indemnification against such liabilities (other than the payment by the 
Registrant of expenses incurred or paid by a director, officer, or 
controlling person of the Registrant in the successful defense of any action, 
suit or proceeding) is asserted by such director, officer or controlling 
person in connection with the securities being registered hereunder, the 
Registrant will, unless in the opinion of its counsel the matter has been 
settled by controlling precedent, submit to a court of appropriate 
jurisdiction the question whether such indemnification by it is against 
public policy as expressed in the Securities Act and will be governed by the 
final adjudication of such issue.

                                  SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, the 
Registrant certifies that it has reasonable grounds to believe that it meets 
all of the requirements for filing on Form S-3 and has duly caused this 
Post-Effective Amendment No. 1 to be signed on its behalf by the undersigned, 
thereunto duly authorized, in the City of San Diego, State of California, on
