(Avax Technologies, Inc. logo appears here)

This Prospectus relates to the offer (the "Offering") by the securityholders
named herein under the caption "Selling Securityholders" (collectively, the
"Selling Securityholders") for sale to the public of the following securities of
AVAX Technologies, Inc. (the "Company"): (i) 570,398 shares of the Company's
common stock, par value $.002 per share (the "Common Stock"); (ii) 12,894,900
shares of Common Stock issuable upon conversion of currently outstanding shares
of Series B Convertible Preferred Stock, par value $.01 per share, of the
Company ("Series B Preferred Stock"); and (iii) 95,300 shares of Common Stock
issuable upon (a) the conversion of shares of Series B Preferred Stock of the
Company issuable upon exercise of the warrants issued to the designees of the
placement agent of the Series B Offering described herein (the "Series B
Placement Warrants") and (b) exercise of warrants issued to the designees of the
placement agent for certain bridge financing transactions of the Company
described herein (the "Bridge Placement Warrants," and together with the Series
B Placement Warrants, the "Placement Warrants"). The number of shares of Common
Stock issuable upon conversion of the Series B Preferred Stock and upon exercise
of the Placement Warrants is subject to adjustment in certain events.

The Company will not receive any proceeds from the sale of shares of Common
Stock. The Company is not expected to receive any proceeds from the exercise of
the Placement Warrants since the Placement Warrants may be exercised pursuant to
a cashless exercise provision. In the event that the Placement Warrants are
exercised for cash, the Company intends to use such net cash proceeds (after
estimated expenses of this Offering of approximately $300,000) for general 
working capital purposes. Proceeds, if any, from the exercise for cash of 
all the Placement Warrants, before deduction of estimated expenses of this
Offering, would be approximately $160,000. Whether, how and to what extent any
of the Placement Warrants will be exercised, and whether the Placement Warrants
are exercised for cash or not, cannot be predicted by the Company.
    


The Selling Securityholders have advised the Company that they may sell,
directly or through brokers, all or a portion of the securities offered hereby
in negotiated transactions or in one or more transactions in the market at the
price prevailing at the time of sale. In connection with such sales, the Selling
Securityholders and any participating broker may be deemed to be "underwriters"
of the Common Stock within the meaning of the Securities Act of 1933. It is
anticipated that usual and customary brokerage fees will be paid by the Selling
Securityholders in all open market transactions. The Company will pay all other
expenses of this Offering. See "Plan of Distribution."

   
The Company will inform the Selling Securityholders that the anti-manipulation
provisions of Regulation M promulgated under the Securities Exchange Act of 1934
may apply to the sales of their shares offered hereby. The Company also will

revenues, and at December 31, 1996, had an accumulated deficit of $3,254,022.
The Company is continuing to incur losses and expects to incur significantly
increasing additional losses for the foreseeable future.

   
The Company has been granted conditional approval for listing and quotation

the Common Stock which may be obtained on any such market are not necessarily
related to the Company's assets, book value, results of operations or any
other established criteria of value, and should not be regarded as any
indication of future market price of the Common Stock. See "Risk Factors,"

 EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
   AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE

                               PROSPECTUS SUMMARY

THE FOLLOWING SUMMARY DOES NOT PURPORT TO BE COMPLETE AND IS QUALIFIED IN ITS
ENTIRETY BY REFERENCE TO THE MORE DETAILED INFORMATION AND THE FINANCIAL
STATEMENTS AND NOTES THERETO APPEARING ELSEWHERE IN THIS PROSPECTUS, INCLUDING,
WITHOUT LIMITATION, THE INFORMATION UNDER "RISK FACTORS," OR INCORPORATED HEREIN
BY REFERENCE, AND, ACCORDINGLY, SHOULD BE READ IN CONJUNCTION THEREWITH.


                                 COMPANY SUMMARY

AVAX Technologies, Inc. ("AVAX" or the "Company"), is a development stage
biopharmaceutical company which intends to acquire rights to, and to develop,
technologies and products for the treatment of cancer and other life-
threatening diseases. The Company initially intends to focus its efforts
primarily on the development of immunotherapies and chemotherapies for cancer.
Immunotheropy is a rapidly developing segment of the cancer therapeutic market.

The Company has licensed (the "TJU License") from Thomas Jefferson University
("TJU") an issued U.S. patent and certain patent applications covering a process
for the modification of a patient's own tumor cells into a cancer vaccine. This
process allows the Company to produce an autologous cell vaccine (an "AC
Vaccine") that attempts to stimulate the patient's immune system to eliminate
the cancer. This technology has emerged from research conducted at TJU and
primarily involves the removal of a patient's own tumor cells, conjugating them
to a small molecule known as a hapten, and reintroducing the product back into
the patient. The approach is based on the premise that a patient's immune
response to a strongly immunogenic, hapten-conjugated tumor antigen may be
followed by the development of an immune response to the unmodified tumor
antigen, somewhat analogous to the phenomenon of drug-induced autoimmune
disease.

   
The Company's initial AC Vaccine, M-Vax(TM), is currently undergoing
physician-sponsored human clinical trials based on an experimental protocol at
TJU as an outpatient, post-surgical, adjunct therapy for the treatment of
melanoma, and is believed by the Company to be the first therapeutic cancer
vaccine to show a substantial increase in the survival rate for patients with
stage 3 melanoma. In such ongoing clinical trials at TJU, over 275 melanoma
patients have been treated post-surgically on an outpatient basis with
M-Vax(TM). In 62 patients with stage 3 melanoma in protocols in which there has
been sufficient time for long-term follow-up, the five-year survival rate is
approximately 60%. This compares with the historical and control group stage 3
survival rate of approximately 20%, and the survival rate for treatment with
high dose alpha interferon of approximately 32% in stage 3 patients whom the
Company believes to be comparable to those treated with M-Vax(TM). The Company
believes that the results to date of the ongoing clinical trial represent the
first substantial increase in survival for stage 3 melanoma patients treated by
immunotherapy. In the over 275 patients treated in studies, the Company believes
that only relatively minor side effects, such as soreness and swelling at the
site of the application of the M-Vax(TM) vaccine, have been witnessed to date.

TJU and Dr. Berd have conducted the ongoing clinical trials at TJU pursuant to
an FDA-approved, physician-sponsored Investigational New Drug Application
("IND"). The Company has recently met with the FDA to discuss the clinical
results obtained with M-Vax(TM), the use of such results in support of the
submission of a Company-sponsored IND to the FDA, and to review its proposed
Phase III program of clinical trials for M-Vax(TM). Depending upon the results
of such clinical trials, it is the Company's intention to use the results of
these Company-sponsored clinical trials along with the results of the clinical
trial conducted at TJU, as the basis for the filing of a New Drug Application
("NDA") for FDA approval to market M-Vax(TM). The Company also may pursue a
similar regulatory approval and commercialization strategy for M-Vax(TM) in
Australia, Canada, Mexico and certain other countries through corporate
partnering strategies, although such strategies have not yet been finalized or
initiated. Denial of any regulatory approvals or any significant 

    


                                       3

<PAGE>

delays in obtaining any of the same, would have a material adverse effect on the
Company.

   
The Company also believes that the AC Vaccine technology may have applications
in the treatment of other cancers, which may include ovarian, breast, prostate,
lung and colorectal cancers and acute myologenous leukemia (AML). The Company
intends to fund the preclinical and initial clinical development of this
technology for at least some of these indications. Accordingly, in addition to
continuing the clinical work on M-Vax(TM), the Company has also entered into a
sponsored research agreement with TJU relating to the development of additional
immunotherapies based on the AC Vaccine technology. For example, the Company is
in the preliminary stages of enrolling patients for its Phase II clinical trial
of O-Vax(TM), its AC Vaccine for ovarian cancer. This trial will be conducted
at TJU under the direction of Dr. David Berd, the inventor of the AC Vaccine
technology. 

    

In order to contain costs, the Company may continue to use sponsored research
agreements and contract research organizations to help it develop its
technologies. At the appropriate time the Company may seek corporate partners to
provide the necessary resources and expertise for clinical development and to
market and distribute products. In addition, the Company may seek to explore the
acquisition and subsequent development and commercialization of additional
commercially promising immunotherapy, chemotherapy and adjuvant technologies. No
assurance can be given that the Company will have the requisite resources or
that any such projects will be identified on terms favorable to the Company, if
at all.

In connection with the Company's strategy to acquire, develop and commercialize
other potential biotechnology products and technologies, the Company recently
licensed from Rutgers University and the University of Medicine and Dentistry of
New Jersey (collectively, "Rutgers"), certain patent applications relating to a
series of compounds for the potential treatment of cancer and infectious
diseases (the "Rutgers License"). The Company also has licensed from The Texas
A&M University System ("Texas A&M"), an issued U.S. patent and certain patent
applications relating to a series of compounds for the potential treatment of
cancer (the "Texas A&M License"). Pursuant to the Rutgers License and the Texas
A&M License, the Company intends to expend substantial resources on the research
and development of these compounds.

The Company may seek to explore the acquisition and subsequent development and
commercialization of additional commercially promising immunotherapy and
adjuvant technologies. No assurance can be given that the Company will have the
requisite resources or that any such projects will be identified on terms
favorable to the Company, if at all.

The Company was incorporated in the State of New York on January 12, 1990, under
the name Nehoc, Inc. On May 29, 1992, it changed its name to Appex Technologies,
Inc. On October 22, 1992, the Company merged into Walden Laboratories, Inc.
("Walden"), a Delaware corporation, which was incorporated on September 18,
1992. On December 27, 1995, Walden sold its former leading product under
development, an over-the-counter nutritional dietary, medicinal and/or
elixorative food supplement or drug and related patents and intellectual
property to a subsidiary of Interneuron Pharmaceuticals, Inc. The Company
changed its name from Walden Laboratories, Inc., to AVAX Technologies, Inc.,
effective March 26, 1996.

   
The Company's office is located at 4520 Main Street, Suite 930, Kansas City,
Missouri 64111. Its telephone number at that address is (816) 960-1333.

Use of Proceeds:                    The Company will not receive any proceeds from the sale of shares of Common Stock.
                                    The Company is not expected to receive any proceeds from the exercise of the
                                    Placement Warrants since the Placement Warrants may be exercised pursuant to a
                                    cashless exercise provision.  In the event that the Placement Warrants are exercised for
                                    cash, the Company intends to use such net cash proceeds (after estimated offering
                                    expenses of this Offering of approximately $300,000) for general working capital
                                    purposes.  Proceeds, if any, from the exercise for cash of all the Placement Warrants,
                                    before deduction of estimated expenses of this Offering, would be approximately
                                    $160,000.  Whether, how and to what extent any of the Placement Warrants will be
                                    exercised, and whether the Placement Warrants are exercised for cash or not, cannot be
                                    predicted by the Company.  See "Use of Proceeds," "Certain Transactions," "Selling

                                  RISK FACTORS

AN INVESTMENT IN THE SHARES OF COMMON STOCK OFFERED HEREBY IS HIGHLY SPECULATIVE
IN NATURE, INVOLVES A HIGH DEGREE OF RISK AND SHOULD NOT BE PURCHASED BY PERSONS
WHO CANNOT AFFORD A LOSS OF THEIR ENTIRE INVESTMENT. EACH PROSPECTIVE INVESTOR
SHOULD CONSIDER CAREFULLY THE RISKS INHERENT IN AND AFFECTING BOTH THE BUSINESS
OF THE COMPANY AND THE VALUE OF THE COMMON STOCK AND SPECULATIVE FACTORS
INCLUDING, WITHOUT LIMITATION, THE FOLLOWING RISK FACTORS, AS WELL AS OTHER
INFORMATION CONTAINED ELSEWHERE IN THIS PROSPECTUS BEFORE MAKING AN INVESTMENT
IN THE COMMON STOCK.

HISTORY OF OPERATING LOSSES; ACCUMULATED DEFICIT; UNCERTAINTY OF FUTURE
PROFITABILITY

   
The Company has incurred substantial operating losses since its inception. As of
December 31, 1996, the Company's accumulated deficit was $3,254,022. The Company
expects to incur significant increasing operating losses over the next several
years, primarily due to the expansion of its research and development programs,
including clinical trials for M-VaxTM and preclinical studies and clinical
trials for other products that it may acquire or develop. The Company's ability
to achieve profitability depends upon, among other things, its ability to
develop products, obtain regulatory approval for its proposed products, and
enter into agreements for product development, manufacturing and
commercialization. The Company's M-VaxTM product does not currently generate
revenue and the Company does not expect to achieve revenues from this or other
products for the foreseeable future. Moreover, there can be no assurance that
the Company will ever achieve significant revenues or profitable operations from
the sale of M-VaxTM or any other products that it may develop.
    

NEED FOR ADDITIONAL FINANCING; ISSUANCE OF SECURITIES; FUTURE DILUTION

In the future, the Company may require substantial additional financing to
continue research, undertake product development and to pursue the manufacturing
and marketing of any products that it may develop. The Company anticipates that
further funds may be raised through additional debt or equity financings
conducted by the Company, or through collaborative ventures entered into between
the Company and potential corporate partners. However, there can be no assurance
that any such offering will be consummated or that the Company will otherwise be
able to obtain additional financing or that such financing, if available, can be
obtained on terms favorable or acceptable to the Company. If such offerings are
not consummated or additional financing is not otherwise available, the Company
will be required to modify its business development plans or reduce or cease
certain or all of its operations.

While the Company may seek to enter into collaborative ventures with corporate
sponsors to fund some or all of its research and development activities, as well
as to manufacture or market any products which may be successfully developed,
the Company currently does not have any such arrangements with corporate
sponsors, and there can be no assurance that the Company will be able to enter
into such ventures on favorable or acceptable terms, if at all. In addition, no
assurance can be given that the Company will be able to complete a subsequent
public offering or private placement of its securities. Failure by the Company
to enter into such collaborative ventures or to receive additional funding to
complete its proposed product development programs either through a private
placement or a public offering could have a material adverse effect on the
Company. In the event that the Company obtains any additional funding, such
financings may have a dilutive effect on the holders of the Common Stock. See
"Risk Factors--Dependence on Third Parties for Additional Funds and for
Manufacturing, Marketing and Selling".

In addition, the Company currently has an employee stock option plan under which
its officers and directors will be eligible to receive stock options exercisable
for Common Stock at exercise prices which may be lower than the current market
price of the Common Stock. Similarly, under employment arrangements with certain
full-time employees and officers of the Company, the Company has granted such
employees and officers options for Common Stock at exercise prices that may be
lower than the prevailing market price of the Common Stock from time to time.
Such stock option grants under the employee stock option plan if any, and to
certain of the full-time employees and officers of the Company, may dilute the
value of the Common Stock. See "Management" and "Description of Securities--1992
Stock Option Plan; Other Options."

DEVELOPMENT STAGE COMPANY

Although the Company was organized in January 1990, it has only conducted
limited research and development activities and has not generated any
significant revenues to date from operations. Accordingly, the Company must be
evaluated in light of the expenses, delays, uncertainties and complications
typically encountered by newly established biopharmaceutical businesses, many of
which uncertainties and complications may be beyond the Company's control. These
include, but are not limited to, unanticipated problems relating to product
development, testing, regulatory compliance, manufacturing, marketing and
competition, and additional costs and expenses that may exceed current
estimates. There can be no assurance that the Company will successfully develop
and commercialize any products, generate any revenues or ever achieve profitable
operations. See "Business."

TECHNOLOGICAL UNCERTAINTY AND EARLY STAGE OF PRODUCT DEVELOPMENT

The technologies and products which the Company intends to develop are in the
early stages of research and development, require significant further research,
development and testing and are subject to the risks of failure inherent in the
development of products based on innovative or novel technologies. These risks
include, but are not limited to, the possibility that any or all of the
Company's proposed products will be found to be ineffective or unsafe, that the
products once developed, although effective, are uneconomical to market, that
third parties hold proprietary rights that preclude the Company from marketing
such products or that third parties market a superior or equivalent product and
that the Company will be unable to secure a meaningful patent position for such
products. See "Uncertainty Regarding Patents and Proprietary Rights."

The Company's agreements with (i) TJU, its licensor for the AC Vaccine
technology, (ii) Rutgers, its licensor for certain anti-cancer and
anti-infective technology and (iii) Texas A&M, its licensor for certain
anti-cancer technology, do not contain any representations by the licensors as
to the safety or efficacy of the inventions or discoveries covered thereby. The
Company is unable to predict whether the research and development activities it
is funding will result in any commercially viable products or applications.
Further, due to the extended testing required before marketing clearance can be
obtained from the United States Food and Drug Administration (the "FDA") or
other similar agencies, the Company is not able to predict with any certainty,
when, if ever, it will be able to commercialize any of its proposed products.

   
The market for biotechnology in general, and for cancer immunotherapies such as
the AC Vaccine technology and other possible future products, in particular, are
characterized by rapidly changing technology, evolving industry standards and
frequent new product introductions. The Company's future success will depend
upon its ability to develop and commercialize its existing product and to
develop new products and features. There can be no assurance that the Company
will successfully complete the development of its existing product or of any
future product or that the Company's current or future products will achieve
market acceptance. Any delay or failure of M-Vax(TM), or of any future product
which the Company may develop, in achieving market acceptance would materially
and adversely affect the Company's business. In addition, there can be no
assurance that products or technologies developed by others will not materially
render the Company's existing or future products or technologies non-competitive
or obsolete.

This Prospectus includes estimates by the Company of the number of patients with
a particular type of cancer or other diseases, the number of patients who were
administered a particular vaccine or drug and the number of patients who
received or might have been candidates for a particular type of treatment. There
can be no assurance that such estimates accurately reflect the true market or
the extent to which any of the Company's products, if successfully developed,
will actually be used by patients. Furthermore, even if patient use occurs,
there can be no assurance that the Company's sales of its products for such uses
will be profitable. Failure of the Company to successfully develop, obtain
regulatory approval for, introduce and market M-Vax(TM) and any possible future
products would have a material adverse effect on the Company.
    


                                        8

GOVERNMENT REGULATION; NO ASSURANCE OF PRODUCT APPROVAL

   
The proposed products of the Company will be subject to very stringent federal,
state and local government regulations, including, without limitation, the
Federal Food, Drug and Cosmetic Act, and its state and local counterparts.
Similar regulatory frameworks exist in other countries where the Company may
consider marketing its products. To date, TJU and Dr. Berd have conducted the
ongoing clinical trials at TJU pursuant to an FDA-approved physician sponsored
Investigational New Drug Application ("IND"). The Company has recently met with
the FDA to discuss the clinical results obtained with M-Vax(TM), the use of such
results in support of the submission of a Company-sponsored IND to the FDA, and
to review its proposed Phase III program of clinical trials for M-Vax(TM). Prior
to marketing M-Vax(TM) or any other possible product the Company may develop,
such product must undergo an extensive regulatory approval process. Any denials
or delays in obtaining requisite approvals would be likely to have a material
adverse effect on the Company. 

    

The regulatory process includes preclinical and clinical testing of any product
to establish its safety and efficacy. This testing can take many years and
require the expenditure of substantial capital and other resources. Delays or
denials of marketing approval are encountered regularly due to the submission of
unacceptable or incomplete data as deemed by the FDA or other similar regulatory
agency, or due to regulatory policy for product approvals. These delays may be
encountered both domestically and abroad. There is no assurance that even after
clinical testing, regulatory approval will ever be obtained. If obtained,
regulatory approval may provide limitations on the indicated uses for which any
products may be marketed. Following regulatory approval, if any, a marketed
product and its manufacturer are subject to continual regulatory review.

   
Later discovery of problems with a product or manufacturer may result in
restrictions on such product or manufacturer. These restrictions may include
withdrawal of the marketing approval for the product. In addition, new
government regulations may be established that could delay or prevent regulatory
approval of the Company's products under development. Failure of the Company to
obtain and maintain regulatory approval of its proposed products, processes or
facilities would have a material adverse effect on the business, financial
condition and results of operations of the Company. In addition, many academic
institutions and companies doing research in the field of cancer immunotherapy
are using a variety of approaches and technologies. Any adverse results obtained
by such researchers in preclinical or clinical studies, even if not directly or
indirectly related to the Company's potential products or approaches, could
adversely affect the regulatory environment for immunotherapy or other 
biotechnology products generally, and possibly lead to delays in the approval 
process for the Company's potential products. See "Business--Government 
Regulation."
    

DEPENDENCE ON OTHERS FOR CLINICAL DEVELOPMENT OF, REGULATORY APPROVALS FOR,
MANUFACTURING AND MARKETING OF PHARMACEUTICAL PRODUCTS

The Company anticipates that it may in the future seek to enter into
collaborative agreements with pharmaceutical or other biotechnology companies
for the development of, clinical testing of, seeking of regulatory approval for,
and manufacturing, marketing and commercialization of, certain of its products.
The Company may in the future grant to its collaborative partners, if any,
rights to license and commercialize any pharmaceutical products developed under
these collaborative agreements and such rights would limit the Company's
flexibility in considering alternatives for the commercialization of such
products. Under such agreements, the Company may rely on its collaborative
partners to conduct research efforts and clinical trials on, obtain regulatory
approvals for, manufacture, market and commercialize certain of the Company's
products. Although the Company believes that its collaborative partners may have
an economic motivation to commercialize the pharmaceutical products which they
may license, the amount and timing of resources devoted to these activities
generally will be controlled by each such individual partner. There can be no
that the Company will be successful in establishing any collaborative
arrangements, or that, if established, such future partners will be successful
in commercializing products or that the Company will derive any revenues from
such arrangements. Although the Company intends to pursue such collaborative
arrangements in the future, there are no specific arrangements, proposals, plans
or understandings with respect to any such collaborative arrangements.



                                        9

<PAGE>




DEPENDENCE ON THIRD PARTIES FOR ADDITIONAL FUNDS AND FOR MANUFACTURING,
MARKETING AND SELLING

   
The Company currently does not have the resources to directly manufacture,
market or sell M-Vax(TM) or any products it may develop in the future.
Accordingly, the Company may be dependent on corporate partners or other
entities for, and may have only limited control over, commercial scale
manufacturing, marketing and selling of its products. The inability of the
Company to acquire such third party manufacturing, distribution, marketing and
selling arrangements for the Company's anticipated products will have a material
adverse effect on the Company's business. There can be no assurance that the
Company will be able to enter into any arrangements for the manufacturing,
marketing and selling of its products. In the event the Company determines to
establish a manufacturing facility, such endeavor will require substantial
additional funds, the hiring and retention of significant additional personnel
and compliance with extensive regulations applicable to such a facility. There
can be no assurance that the Company will be able to successfully establish such
a facility, hire such personnel or successfully manufacture products for sale at
competitive prices. See "Business--Manufacturing and Marketing." 
    

DEPENDENCE ON LICENSES AND SPONSORED RESEARCH AGREEMENTS

   
The Company relies heavily on third parties for a variety of functions,
including certain functions relating to research and development. As of April 1,
1997, the Company had only five full-time employees. The Company is party to
several license and research agreements which place substantial responsibility
on the Company's licensors for research and clinical development of its products
and technologies. 
    

In particular, the Company is dependent upon the TJU License as the basis of its
proprietary AC Vaccine technology and is dependent upon a sponsored research
agreement with TJU for research and development efforts in connection therewith.
Pursuant to the TJU License, the Company is obligated to pay an up-front license
fee, to use due diligence in developing and bringing products to market and to
make certain payments upon the achievement of certain milestones. The Company is
also obligated to make royalty payments on the sales, if any, of products
resulting from such licensed technology and, is responsible for the costs of
filing and prosecuting patent applications and maintaining issued patents. In
addition, the Company is required to invest a minimum amount per year in the AC
Vaccine technology as well as sponsored research at TJU. The Company is
similarly dependent upon the Rutgers License and Texas A&M License for certain
of its technology, and has financial and other obligations thereunder which are
similar to those under the TJU agreements.

As the Company currently does not have laboratory facilities, the Company's
research and development activities are intended to be conducted by universities
or other institutions pursuant to sponsored research agreements. The sponsored
research agreement entered into by the Company, TJU and Dr. Berd generally
requires periodic payments by the Company to TJU on a quarterly basis. There are
similar types of obligations under the Rutgers License and Texas A&M License.

If the Company does not meet its financial and other obligations in a timely
manner under its license agreements or related sponsored research agreements,
the Company could lose the rights to its proprietary technology or the right to
have its licensors and others conduct its research and development efforts, any
of which could have a material adverse effect on the Company.

UNCERTAINTY REGARDING PATENTS AND PROPRIETARY RIGHTS

The biotechnology industry places considerable importance on obtaining patent
and trade secret protection for new technologies, products and processes. The
success of the Company will depend in substantial part on its ability, on the
ability of its current licensors and on the ability of its potential future
licensors, if any, to obtain patents, defend such patents, maintain trade
secrets and operate without infringing upon the proprietary rights of others,
both in the United States and in foreign countries. The patent position of firms
relying upon biotechnology is highly uncertain and involves complex legal and
factual questions. To date there has emerged no consistent policy regarding the
breadth of claims allowed in biotechnology patents or the degree of protection
afforded under such patents.


                                       10

<PAGE>




More specifically, the Company relies on TJU's issued patent for the AC Vaccine
technology and may rely on certain United States patents and pending patent
applications, as well as a pending foreign Patent Cooperation Treaty ("PCT")
application, relating to various aspects of its present and future products and
processes. The patent application and issuance process can be expected to take
several years and could entail considerable expense to the Company, as it may be
responsible for such costs under the terms of any technology agreements. There
can be no assurance that patents will issue as a result of any applications or
that the existing patents and any patents resulting from such applications, will
be sufficiently broad to afford protection against competitors with similar
technology. In addition, there can be no assurance that such patents will not be
challenged, invalidated, circumvented, or that the rights granted thereunder
will provide competitive advantages to the Company. The commercial success of
the Company will also depend upon avoiding infringement of patents issued to
competitors. A United States patent application is maintained under conditions
of confidentiality while the application is pending, so the Company cannot
determine the inventions being claimed in pending patent applications filed by
third parties. As a result, the Company cannot be certain that its scientists
were the first to make inventions covered by its patents and patent
applications.

In the event a third party has also filed a patent application relating to an
invention claimed in a Company patent application, the Company or its licensor
may be required to participate in an interference proceeding in the United
States Patent and Trademark Office to determine priority of the invention, which
could result in substantial uncertainties and cost for the Company, even if the
eventual outcome is favorable to the Company. An adverse outcome could subject
the Company to significant liabilities to third parties and require the Company
to license disputed rights from third parties at an undeterminable cost or to
cease using the technology. There can be no assurance that the validity or
enforceability of the Company's patents, if issued, would be upheld by a court.
While no patent that could be potentially infringed by manufacture, use or sale
of the Company's product candidates has come to the attention of the Company,
the Company's product candidates are still in the development stage, and neither
their formulations nor their method of manufacture have been finalized. Thus,
there can be no assurance that the manufacture, use or sale of the Company's
product candidates will not infringe patent rights of others. The Company may be
unable to avoid infringement of any such patents and may have to seek a license,
defend an infringement action, or challenge the validity of the patents in
court. There can be no assurance that a license will be available to the
Company, if at all, upon terms and conditions acceptable to the Company or that
the Company will prevail in any patent litigation. Litigation may be necessary
to defend or enforce the Company's patent and license rights or to determine the
scope and validity of others' proprietary rights. Defense and enforcement of
patent claims can be expensive and time consuming, even in those instances in
which the outcome is favorable to the Company, and can result in the diversion
of substantial resources from the Company's other activities. There can be no
assurance that the Company will have sufficient resources to pursue such
litigation. If the Company does not obtain a license under any such patents, is
found liable for infringement, or is not able to have them declared invalid, the
Company may be liable for significant money damages, may encounter significant
delays in bringing products to market, or may be precluded from participating in
the manufacture, use or sale of products or methods of treatment covered by such
patents, any of which could have a material adverse effect on the Company's
business, results of operation and financial condition. See "Business--
Proprietary Technology."

In its product development activities, the Company relies substantially on
certain technologies which are not patentable or proprietary and are therefore
available to the Company's competitors. The Company also relies on certain
proprietary trade secrets and know-how which are not patentable. Although the
Company has taken steps to protect its unpatented trade secrets and know-how, in
part through the use of confidentiality agreements with its employees,
consultants and certain of its contractors, there can be no assurance that these
agreements will not be breached, that the Company would have adequate remedies
for any breach or that the Company's trade secrets will not otherwise become
known or be independently developed or discovered by competitors. If the
Company's employees, scientific consultants or collaborators develop inventions
or processes independently that may be applicable to the Company's product
candidates, disputes may arise about ownership of propriety rights to those
inventions and processes. Such inventions and processes will not necessarily
become the Company's property, but may remain the property of those persons or
their employers. Protracted and costly litigation could be necessary to enforce
and determine the scope of the Company's proprietary rights. Failure to obtain
or maintain patent and trade secret protection, for any reason, could have a
material adverse effect on the Company. Certain of the Company's patents are
directed to inventions developed within academic institutions (from which the
Company earlier acquired rights to such patents) with funds from United States
government agencies. As a result of these arrangements, the

                                       11

<PAGE>




United States government may have rights in certain inventions developed during
the course of the performance of federally funded projects as required by law or
agreements with the funding agency. Several bills affecting patent rights have
been introduced in the United States Congress. These bills address various
aspects of patent law, including publication, patent term, re-examination,
subject matter and enforceability. It is not certain whether any of these bills
will be enacted into law or what form new laws may take. Accordingly, the effect
of legislative change on the Company's intellectual property rights is
uncertain.

CONDUCTING BUSINESS ABROAD

To the extent the Company conducts business outside the United States, it
intends to do so through licenses, joint ventures or other contractual
arrangements for the development, manufacturing and marketing of its products.
No assurance can be given that the Company will be able to establish foreign
operations successfully through such a plan, that the foreign PCT application
will be approved, that the foreign PCT coverage will be available or that the
manufacturing and marketing of its products through such licenses, joint
ventures other arrangements will be commercially successful. The Company might
also have greater difficulty obtaining proprietary protection for its products
and technologies outside the United States and enforcing its rights in foreign
courts.

For clinical investigation and marketing outside the United States, the Company
also is subject to foreign regulatory requirements governing human clinical
trials and marketing approval for drugs. The requirements governing the conduct
of clinical trials, product licensing, pricing and reimbursement vary widely for
European countries both within and outside the European Community ("EC").
Outside the United States, the Company's ability to market a product is
contingent upon receiving a marketing authorization from the appropriate
regulatory authority. At present, foreign marketing authorizations are applied
for at a national level, although with the EC certain registration procedures
are available to companies wishing to market their products in more than one EC
member state. If the regulatory authority is satisfied that adequate evidence of
safety, quality and efficacy has been presented, a marketing authorization will
be granted. The system for obtaining marketing authorizations within the EC
registration system is a dual one in which certain products, such as
biotechnology and high technology products and those containing new active
substances, will have access to a central regulatory system that provides
registration throughout the entire EC. Other products will be registered by
national authorities in individual EC member states, operating on a principle of
mutual recognition. This foreign regulatory approval process includes, at least,
all of the risks associated with FDA approval set forth above. The Company could
possibly have greater difficulty in obtaining any such approvals and also might
find it more difficult to protect its intellectual property abroad.

DEPENDENCE UPON KEY PERSONNEL AND CONSULTANTS

   
The Company will be highly dependent upon its officers and directors, as well as
its Scientific Advisory Board members, consultants and collaborating scientists.
Except for its five full-time employees, each of the Company's officers,
directors, advisors and consultants devotes only a portion of his or her time to
the Company's business and for the most part are involved with other
substantially full-time activities. The loss of certain of these individuals,
including, without limitation, Jeffrey M. Jonas, M.D., the Company's President
and Chief Executive Officer, could have a material adverse effect on the Company
unless the Company could promptly hire qualified replacements. The Company
maintains a key-man life insurance policy on Dr. Jonas in the amount of only $3
million. In addition, each of the Company's full-time employees and officers
have only recently joined the Company. Although the Company has entered into
letters of employment with its full-time employees and officers, such letters of
employment do not contain provisions which would prevent any of them from
resigning at any time. See "Management". 
    

Competition for qualified employees among pharmaceutical and biotechnology
companies is intense, and the loss of any of such persons, or an inability to
attract, retain and motivate any additional highly skilled employees required
for the expansion of the Company's activities, could have a material adverse
effect on the Company. There can be no assurance that the Company will be able
to retain its existing personnel or to attract additional qualified employees
and such failure likely would have a material adverse effect on the Company.

LACK OF MANUFACTURING FACILITIES

   
In order to successfully commercialize its product candidates, the Company must
be able to manufacture its products in commercial quantities, in compliance with
regulatory requirements, at acceptable costs and in a timely manner. The
manufacture of the types of biopharmaceutical products that are likely to be
developed by the Company present several risks and difficulties. For example,
the manufacture of M-Vax(TM) and other compounds the Company may develop for use
in the Company's current and future products and technologies is complex, can be
difficult to accomplish even in small quantities, can be difficult to scale-up
when large scale production is required and can be subject to delays,
inefficiencies and poor or low yields of quality products. The Company may also
be subject to risks relating to the expense, or unavailability of, products and
compounds manufactured or sold by third parties which are required for use on a
comparative basis in clinical trials and studies for the Company's products.
There can be no assurance that the Company will be able to procure such products
and compounds at an acceptable cost or in sufficient quantities without delays
or other adverse effects upon the Company's development programs.
    

The Company does not currently have any manufacturing facilities. Accordingly,
the Company expects to expand its manufacturing staff and facilities and to
establish such a facility or facilities or to contract with third parties to
assist it with production. In employing third party manufacturers, the Company
would not control all aspects of the manufacturing process. There can be no
assurance that the Company will be able to obtain from third party manufacturers
adequate supplies in a timely fashion for commercialization, or that commercial
quantities of any such products, if approved for marketing, will be available
from contract manufacturers at acceptable costs. In the event the Company
decides to establish a full-scale commercial manufacturing facility, the Company
will require substantial additional funds and will be required to hire and train
significant numbers of employees and comply with the extensive regulations
applicable to such a facility. There is no assurance that AVAX will be able to
develop a current Good Manufacturing Practices ("cGMP") manufacturing facility
sufficient for all clinical trials or commercial-scale manufacturing. The cost
of manufacturing certain products may make them prohibitively expensive. In
addition, in order to successfully commercialize its product candidates, the
Company may be required to reduce the cost of production, and there can be no
assurance that the Company will be able to do so. See "Business--Manufacturing
and Marketing."

COMPETITION

The Company's proposed cancer immunotherapy business is characterized by
intensive research efforts and intense competition. Many companies, research
institutes, hospitals and universities are working to develop products and
processes in the Company's fields of research. Most of these entities have
substantially greater financial, technical, manufacturing, marketing,
distribution and other resources than the Company. Certain of such companies
have experience in undertaking testing and clinical trials of new or improved
products similar in nature to that which the Company is developing. In addition,
certain competitors have already begun testing similar compounds or processes
and may introduce such products or processes before the Company. Accordingly,
other companies may succeed in developing products earlier than the Company or
that are more effective than those proposed to be developed by the Company.
Further, it is expected that competition in the Company's field will intensify.
There can be no assurance that the Company will be able to compete successfully
in the future. See "Business--Competition."

RISK OF PRODUCT LIABILITY

Should the Company develop and market any products, the marketing of such
products, through third-party arrangements or otherwise, may expose the Company
to product liability claims. Though the Company presently carries product
liability insurance, there can be no assurance that such insurance will protect
the Company against all claims of product liability. The Company may be required
to indemnify its licensor against certain product liability claims incurred as a
result of the products developed by the Company. The Company's licensors have
not made, and are not expected to make, any representations as to the safety or
efficacy of the inventions covered by the license or as to any products which
may be made or used under rights granted therein or thereunder. In addition, it
is possible that license and collaborative agreements which the Company may
enter into in the future may also include similar insurance requirements. There
can be no assurance that

                                       13

<PAGE>




in the future adequate insurance coverage will be available in sufficient
amounts or at a reasonable cost, or that a product liability claim or recall
would not have a material adverse effect on the Company.

UNCERTAINTY OF PRODUCT PRICING AND REIMBURSEMENT; HEALTH CARE REFORM AND RELATED
MEASURES

The levels of revenues and profitability of pharmaceutical and/or biotechnology
products and companies may be affected by efforts of governmental and third
party payors to contain or reduce the costs of health care through various
means. For example, in certain foreign markets, pricing or profitability of
prescription pharmaceuticals is subject to government control. In the United
States there have been, and the Company expects that there will continue to be,
a number of federal and state proposals to implement similar government control.
Presently, the United States Congress is considering a number of legislative and
regulatory reforms that may affect companies engaged in the health care industry
in the United States. Pricing constraints on the Company's products, if
approved, could have a material adverse effect on the Company. Although the
Company cannot predict whether these proposals will be adopted or what effects
such proposals may have on its business, the existence and pendency of such
proposals could have a material adverse effect on the Company in general. In
addition, the Company's ability to commercialize potential pharmaceutical and/or
biotechnology products may be adversely affected to the extent that such
proposals have a material adverse effect on other companies that are prospective
collaborators with respect to any of the Company's product candidates.

In addition, in the United States and elsewhere, sales of medical products and
services are dependent in part on the availability of reimbursement to the
consumer from third party payors, such as government and private insurance
plans. Third party payors are increasingly challenging the prices charged for
medical products and services. If the Company succeeds in bringing one or more
products to the market, there can be no assurance that these products will be
considered cost effective and that reimbursement to the consumer will be
available or will be sufficient to allow the Company to sell their products on a
competitive basis. See "Risk Factors--Government Regulation; No Assurance of
Product Approval."

NO ASSURANCE OF IDENTIFICATION OF ADDITIONAL PROJECTS; CERTAIN INTERLOCKING
RELATIONSHIPS; POTENTIAL CONFLICTS OF INTEREST

   
The Company initially intends to be engaged primarily in the development and
commercialization of the AC Vaccine technology, as well as the potential
anti-cancer and anti-infective technology licensed pursuant to the Rutgers
License and the potential anti-cancer technology licensed pursuant to the Texas
A&M License. See "Business." From time to time, if and when the Company's
resources allow, the Company may explore the acquisition and subsequent
development and commercialization of additional biomedical and pharmaceutical
products and technologies. However, there can be no assurance that the Company
will be able to identify any additional products or technologies and, even if
suitable products or technologies are identified, there can be no assurance that
the Company will have sufficient resources to pursue any such products or
technologies in the foreseeable future.

    

Certain of the directors of the Company are officers of Paramount Capital
Investments, LLC. See "Management." Paramount Capital Investments, LLC, is a
merchant bank specializing in biotechnology companies. In the regular course of
its business, Paramount Capital Investments, LLC, identifies, evaluates and
pursues investment opportunities in biomedical and pharmaceutical products,
technologies and companies. Generally, Delaware corporate law requires that any
transactions between the Company and any of its affiliates be on terms that,
when taken as a whole, are substantially as favorable to the Company as those
then reasonably obtainable from a person who is not an affiliate in an
arms-length transaction. Nevertheless, neither Paramount Capital Investments,
LLC, nor any other person is obligated pursuant to any agreement or
understanding with the Company to make any additional products or technologies
available to the Company, and there can be no assurance, and purchasers of the
Common Stock should not expect, that any biomedical or pharmaceutical product or
technology identified by Paramount Capital Investments, LLC, or any other person
in the future will be made available to the Company. In addition, certain of the
officers, directors, consultants and advisors to the Company may from time to
time serve as officers, directors, consultants or advisors to other
biopharmaceutical or biotechnology companies. There can be no assurance that
such other companies will not in the future have interests in conflict with
those of the Company.


                                       14

<PAGE>




CONTROL BY CURRENT OFFICERS, DIRECTORS AND PRINCIPAL STOCKHOLDERS

   
The Company's directors, executive officers and principal stockholders
beneficially own approximately 64.80% of the outstanding shares of Common Stock.
Accordingly, the Company's executive officers, directors, principal stockholders
and certain of their affiliates have the ability to exert substantial influence
over the election of the Company's Board of Directors and the outcome of issues
submitted to the Company's stockholders. See "Principal Stockholders."
    

VOLATILITY OF STOCK PRICE

The market price of the Common Stock like that of many other development-stage
public pharmaceutical or biotechnology companies, may be highly volatile.
Factors such as announcements of technological innovations or new commercial
products by the Company or its competitors, disclosure of results of preclinical
and clinical testing, adverse reactions to products, governmental regulation and
approvals, developments in patent or other proprietary rights, public or
regulatory agency concerns as to the safety of any products developed by the
Company and general conditions may have a significant or adverse effect on the
market price of the Common Stock. Also, the trading price of the Common Stock
may respond to quarterly variations in operating results, announcements of
innovations or new products by the Company or its competitors and other events
or factors, including, but not limited to, the sale or attempted sale of a large
amount of such securities into the market. In addition, market fluctuations may
adversely affect the market prices of such securities. See "Description of
Securities."

POTENTIAL ADVERSE EFFECT OF SHARES ELIGIBLE FOR FUTURE SALE

   
As of April 1, 1997, 6,222,316 shares of Common Stock were issued and
outstanding of which the Company believes that 4,305,309 shares of Common Stock
are "restricted securities" and under certain circumstances may, in the future,
be sold in compliance with Rule 144 under the Securities Act, unless they are
held by "affiliates" of the Company as that term is used under the Securities
Act. Assuming the availability of Rule 144, including the requirement that there
is adequate current public information with respect to the Company as
contemplated by Rule 144, the Company believes that of the 4,305,309
"restricted" shares of Common Stock, 905,376 shares of Common Stock are
presently eligible for sale and an additional (i) 1,806,571 shares of Common 
Stock will be eligible for sale in the latter part of 1997 and 
(ii) 1,593,362 shares of Common Stock will be eligible in 1998, 
in each case pursuant to Rule 144 and subject to certain volume limitations 
and manner of sale requirements imposed by Rule 144. In general, 
under Rule 144 as currently in effect, subject to the
satisfaction of certain other conditions, a person, including an affiliate of
the Company, who beneficially owned restricted shares of Common Stock for at
least two years is entitled to sell, within any three-month period, a number of
shares that does not exceed the greater of one percent of the total number of
outstanding shares of the same class, or if the Common Stock is quoted on the
Nasdaq National Market or Nasdaq SmallCap Market, any other national securities
exchange or the OTC Bulletin Board, the average weekly trading volume during the
four calendar weeks immediately preceding the sale. A person who presently is
not and who has not been an affiliate of the Company for at least three months
immediately preceding the sale and who has beneficially owned the shares of
Common Stock for at least three years is entitled to sell such shares under Rule
144(k) without regard to the volume limitations described above. In addition,
the Commission has recently adopted revisions to Rule 144 and Rule 144(k), the
effect of which will be to shorten the holding period under Rule 144 from two
years to one year and to shorten the holding period under 144(k) from three
years to two years.

In addition, the Company has issued and outstanding or issuable warrants and
options to purchase an aggregate of 1,901,783 shares of Common Stock (excluding
shares of Common Stock underlying Series B Placement Warrants and Bridge
Placement Warrants that are being registered in this Offering). Any employee,
officer or director of the Company who acquired his or her shares prior to the
effective date of the Registration Statement at a time when the Company was not
subject the reporting requirements of Section 13 or 15(d) of the Securities
Exchange Act of 1934 (the "Exchange Act") or who holds vested options as of the
effective date of the Registration Statement, pursuant to a written compensatory
plan or contract is entitled to rely on the resale provisions of Rule 701. Rule
701 permits non-affiliates to sell their Rule 701 shares without having to
comply with the public information, holding period, volume limitation or notice
provisions of Rule 144 and permits affiliates to sell their Rule 701 shares
without having to comply with Rule 144's holding period restrictions, in each
case commencing 90 days after the effective date of the Registration Statement.
    

                                       15

No prediction can be made as to the effect, if any, that sales of shares of
Common Stock or the availability of such shares for sale will have on the market
prices that may be quoted from time to time on the OTC Bulletin Board, or the
Nasdaq SmallCap Market when quoted thereon. Nevertheless, the possibility that
substantial amounts of Common Stock may be sold in the public market may
adversely effect the prevailing market prices for the Common Stock and could
impair the Company's ability to raise capital in the future through the sale of
equity securities. Actual sales of Common Stock under Rule 144 or otherwise may
also have a depressive effect upon the price of the Common Stock and the market
therefor. 
    

LIMITED PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK PRICE

   
The Company has been granted conditional approval for listing and quotation 
of the Common Stock on the Nasdaq Small Cap Market. There can be no assurance 
that the Company will satisfy the conditions of such approval. Prior to this 
Offering, the public market for the Common Stock has been limited to shares 
eligible for trading under Rule 144(k) under the Securities Act on the OTC 
Bulletin Board. There can be no assurance that an active trading market 
will develop or be sustained after the Offering. The absence of an active 
trading market would reduce the liquidity of an investment in the Common 
Stock. To the extent that brokerage firms act as market makers, they 
may be a dominating influence in any market that might develop, and the 
degree of participation by such firms may significantly affect the price and 
liquidity of the Common Stock. These firms may discontinue such activities at 
any time or from time to time. The prices at which the Common Stock may be 
offered in the market will be determined by these firms and the purchasers and
sellers of the Common Stock, based in part on market factors, and may not
necessarily relate to the Company's assets, book value, results of operations or
other established and quantifiable criteria of value. The trading price of the
Common Stock, including, without limitation, any Common Stock to be offered by
the Selling Shareholders, could be subject to wide fluctuations in response to
quarterly variations in operating results, announcements of technological
innovations or new products by the Company or its competitors and other events
or factors. In addition, the stock market has experienced volatility that has
particularly affected the market prices of equity securities of many
biotechnology companies and that often has been unrelated to the operating
performance of such companies. These broad market fluctuations may affect
adversely the market price of the Common Stock. See "Plan of Distribution."

UNCERTAINTY OF LISTING ON NASDAQ SMALLCAP MARKET; MARKET ILLIQUIDITY

Shares of Common Stock that are freely tradeable pursuant to Rule 144(k) under
the Securities Act currently are traded on the OTC Bulletin Board. Although 
the Common Stock has been conditionally approved for listing and quotation on 
the Nasdaq SmallCap Market, there can be no assurance that the Company will 
satisfy the conditions of such approval.

If the conditions to receive such approval are met, continued inclusion of the 
Common Stock on the Nasdaq SmallCap Market currently requires that: (i) the 
Company have total assets of $2,000,000 and capital and surplus of at least 
$1,000,000; (ii) the Company's public float have a market value of at least 
$1 million; (iii) the minimum bid price for the Common Stock be at least 
$1.00 per share; and (iv) the Common Stock have at least two active
market makers. A deficiency in either the market value of the public float or
the bid price maintenance standard will be deemed to exist if the issuer fails
the individual stated requirement for 10 consecutive trading days. If an issuer
falls below the bid price maintenance standard, it may remain on the Nasdaq
SmallCap Market if the market value of the public float is at least $1,000,000
and the issuer has $2,000,000 in equity. Recently, the Nasdaq SmallCap Market
has proposed new maintenance critieria which, if implemented, would eliminate
the exception to the $1.00 per share minimum bid price and require, among other
things, $2,000,000 in net tangible assets, $1,000,000 market value of the public
float and adherence to certain corporate governance provisions. There can be no
assurance that the Company and the Common Stock will continue to satisfy the
requirements for maintaining a listing on the Nasdaq SmallCap Market. If the
Company is unable to satisfy the maintenance requirements as they may be in
effect from time to time, the Common Stock may be delisted from the Nasdaq
SmallCap Market. In such event, trading, if any, in the Common Stock would
thereafter probably be conducted on the OTC Bulletin Board or in the
over-the-counter market in the "pink sheets," and the Company would be required
to comply with the Nasdaq SmallCap Market's initial listing criteria in order to
have the Common Stock approved for listing and quotation thereon. Consequently,
the liquidity of the Common Stock could be impaired materially and adversely,
not only in the number of securities that can be bought and sold at a given
price, but also through delays in the timing of transactions and reduction in
security analysts' and media coverage of the Company, which could result in
lower prices for the Common Stock than might otherwise be attained and could
also result in a larger spread between the bid and asked prices for the Common
Stock. See "Risks of Low Price Stock; Possible Effect of "Penny Stock" Rules on
Liquidity for the Common Stock."

RISKS OF LOW-PRICED STOCK; POSSIBLE EFFECT OF "PENNY STOCK" RULES ON LIQUIDITY
FOR THE COMMON STOCK

   
The Exchange Act requires additional disclosure relating to the market for penny
stocks in connection with trades in any stock defined as a penny stock. The
Commission's regulations generally define a penny stock to be any equity
security that has a market price of less than $5.00 per share, subject to
certain exceptions. Such exceptions include any equity security listed on the
Nasdaq SmallCap Market, subject to certain trade reporting requirements, and any
equity security issued by an issuer that has (i) net tangible assets of at least
$2 million, if such issuer has been in continuous operation for three years,
(ii) net tangible assets of at least $5 million, if such issuer has been in
continuous operation for less than three years, or (iii) average annual revenue
of at least $6 million, if such issuer has been in continuous operation for less
than three years. Though the Company believes that it currently meets the net
tangible assets test, there can be no assurance that the Company will meet the
requirements of the foregoing financial exceptions. Thus, if the price per share
of the Common Stock were to be less than $5.00 per share and the Company was
unable to continue to meet the requirements for listing on the Nasdaq SmallCap
Market, failure to qualify under one of the foregoing exceptions would require
delivery, prior to any transaction in a penny stock, of a disclosure schedule
prepared by the Commission relating to the penny stock market. Disclosure is
also required to be made about sales commissions payable to both the
broker-dealer and the registered representative and current quotations for the
securities. Finally, monthly statements are required to be sent disclosing
recent price information for the penny stock held in the account and information
on the limited market in penny stocks. In any event, even if the Common Stock
were exempt from such restrictions, they would remain subject to Section
15(b)(6) of the Exchange Act, which gives the Commission the authority to
prohibit any person that engages in unlawful conduct while participating in a
distribution of penny stock from associating with a broker-dealer or
participating in a distribution of penny stock, if the Commission finds that
such a restriction would be in the public interest. Accordingly, if the Common
Stock is subject to the rules on penny stocks, the market liquidity for such
securities could be materially and adversely affected.

In addition, if the Common Stock fails to meet the minimum market price, the net
tangible asset or the annual revenue tests set forth above, but is quoted on the
OTC Bulletin Board (as to which there can be no assurance), then trading in the
Common Stock would be regulated pursuant to Rules 15-g-1 through 15-g-6 and
15-g-9 promulgated under the Exchange Act for non-National Association of
Securities Dealers Automotive Quotation System and non-exchange listed
securities. Under such rules, broker-dealers who recommend such securities to
persons other than established customers and "accredited investors" must make a
special written suitability determination that the penny stock is a suitable
investment for the purchaser and receive the purchaser's written agreement to
this transaction. Securities are exempt from these rules if the market price of
the Common Stock is at least $5.00 per share. Consequently, such Exchange Act
rules may affect the ability of broker-dealers to make a market in such shares
and may affect the ability of holders of Common Stock to sell in the secondary
market. 
    

ANTITAKEOVER EFFECTS OF PROVISIONS OF THE CERTIFICATE OF INCORPORATION AND
DELAWARE LAW

The Company's Articles of Incorporation, as amended, authorize the issuance of
up to 5,000,000 shares of preferred stock, par value $.01 per share, of which
300,000 shares are authorized for issuance as shares of Series B Preferred
Stock, of which approximately 25,820 have been issued or reserved for issuance
upon the exercise of Series B Placement Warrants. The Company's Certificate of
Incorporation authorizes the issuance of "blank check" preferred stock with such
designation, rights and preferences as may be determined from time to time by
the Board of Directors. Accordingly, the Board of Directors is empowered,
without stockholder approval, to issue a new series of preferred stock with
dividend, liquidation, conversion, voting or other rights which could adversely
affect the voting power or other rights of the holders of the Common Stock. In
the event of issuance, the new series of preferred stock could be utilized,
under certain circumstances, as a method of discouraging, delaying or preventing
a change in control of the Company. Although the Company has no present
intention to issue any additional shares of its preferred stock, other than
those already authorized for issuance upon exercise of the Placement Warrants,
there can be no assurance that the Company will not do so in the future. See
"Description of Securities."

The Company is subject to Section 203 of the General Corporation Law of the
State of Delaware which, subject to certain exceptions, prohibits a Delaware
corporation from engaging in any business combination with any interested
stockholder for a period of three years following the date that such stockholder
became an interested stockholder. In general, Section

                                       17

<PAGE>




203 defines an interested stockholder as any entity or person beneficially
owning 15% or more of the outstanding voting stock of the corporation and any
entity or person affiliated with or controlling or controlled by such entity or
person. The foregoing provisions could have the effect of discouraging others
from making tender offers for the Company's shares and, as a consequence, they
also may inhibit fluctuations in the market price of the Company's shares that
could result from actual or rumored takeover attempts. Such provisions also may
have the effect of preventing changes in the management of the Company.

POTENTIAL CONVERSION PRICE RESET OF SERIES B PREFERRED STOCK

In 1996, the Company consummated an offering of units consisting of shares of
Series B Preferred Stock and Common Stock. The 259,198 shares of Series B
Preferred Stock sold in such offering are convertible at the option of the
holders thereof into shares of Common Stock, at an initial conversion rate of 50
shares of Common Stock per share of Series B Preferred Stock, corresponding to a
conversion price equal to $2.00 per share. The conversion price (and,
consequently the number of shares of Common Stock issuable upon conversion) is
subject to a reset upon the happening of certain events. See "Description of
Securities--Conversion." Any such reset of the conversion price applicable to
the Series B Preferred Stock would result in the issuance of additional shares
of Common Stock upon conversion of the Series B Preferred Stock, and would have
a dilutive effect on purchasers of the Common Stock offered hereby.

In addition, in consideration for their agreement to extend the "lock-up"
provisions described below which are applicable to the shares of Common Stock
issuable upon conversion of the Series B Preferred Stock, certain holders of
shares of Series B Preferred Stock are entitled to be issued additional shares
of Common Stock upon the happening of certain events. See "Description of
Securities--Lock-Up." The occurrence of such an event and the issuance of the
additional shares of Common Stock would have a dilutive effect on purchasers of
the Common Stock offered hereby.

FORWARD LOOKING STATEMENTS

   
Certain of the statements set forth in this Prospectus, including, without
limitation, the Company's research and development programs, the possible filing
of INDs or NDAs for M-Vax(TM) or any other products the Company may develop, the
seeking of joint development or licensing arrangements with pharmaceutical
companies, the research and development of particular compounds and technologies
for particular indications and the period of time for which the Company's
existing resources will enable the Company to fund its operations and to meet
the listing requirements for the quotation of its securities on the Nasdaq
SmallCap Market and the possibility of contracting with other parties additional
licenses to develop, manufacture and market commercially viable products, are
forward-looking and based upon the Company's current belief as to the outcome,
occurrence and timing of future events or current expectations and plans. All
such statements involve significant risks and uncertainties. Many important
factors affect the Company's ability to achieve the stated outcomes and to
successfully develop and commercialize its product candidates, including, among
other things, the ability to obtain substantial additional funds, obtain and
maintain all necessary patents or licenses, to demonstrate the safety and
efficacy of product candidates at each state of development, to meet applicable
regulatory standards and receive required regulatory approvals, to meet
obligations and required milestones under its license agreements, to be capable
of producing drug candidates in commercial quantities at reasonable costs, to
compete successfully against other products and to market products in a
profitable manner. Although the Company believes that its assumptions underlying
the forward-looking statements are reasonable, any of the assumptions could
prove inaccurate and, therefore, there also can be no assurance that these
statements included in the Prospectus will prove to be accurate. In light of the
significant uncertainties inherent in these statements included herein, the
inclusion of such information should not be regarded as a representation by the
Company or any other person that the objectives and plans of the Company will be
achieved. 
    

NO DIVIDENDS

The Company has never paid cash dividends on its capital stock and does not
anticipate paying any cash dividends for the foreseeable future. See "Dividend
Policy."

                                 USE OF PROCEEDS

The Company will not receive any proceeds from the sale of shares of Common
Stock. The Company is not expected to receive any proceeds from the exercise of
the Placement Warrants since the Placement Warrants may be exercised pursuant to
a cashless exercise provision. In the event that the Placement Warrants are
exercised for cash, the Company intends to use such net cash proceeds (after
estimated offering expenses of this Offering of approximately $300,000) for
general working capital purposes. Proceeds, if any, from the exercise for cash
of all the Placement Warrants, before deduction of estimated expenses of this
Offering, would be approximately $160,000. Whether, how and to what extent any
of the Placement Warrants will be exercised, and whether the Placement Warrants
are exercised for cash or not, cannot be predicted by the Company.


            MARKET FOR COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

   
The Common Stock has been publicly traded on the OTC Bulletin Board under the
symbol "AVAX" since December 19, 1996. The following table sets forth, for the
periods indicated, the high and low closing bid prices for the Common Stock, as
reported by the National Quotation Bureau, for the quarters presented. The
prices set forth below represent inter-dealer quotations, without adjustment for

                                 DIVIDEND POLICY

The Company has not paid any cash dividends on its Common Stock since its
formation. The payment of dividends, if any, in the future, with respect to the
Common Stock, is within the discretion of the Board of Directors of the Company
and will depend on the Company's earnings, capital requirements, financial
condition and other relevant factors. The Board of Directors of the Company does
not presently intend to declare any dividends on the Common Stock in the
foreseeable future. The Company anticipates that all earnings and other
resources of the Company, if any, will be retained by the Company for investment
in its business.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                   FINANCIAL CONDITION AND PLAN OF OPERATIONS

GENERAL

   
Since its inception, the Company has concentrated its efforts and resources in
the development and commercialization of biotechnology and pharmaceutical
products and technologies. The Company has been unprofitable since its founding
and has incurred a cumulative net loss of $3,254,022 as of December 31, 1996.
The Company expects to incur significantly increasing operating losses over the
next several years, primarily due to the expansion of its research and
development programs, including clinical trials for M-Vax(TM), and other
preclinical studies and clinical trials for other products that may arise from
the AC Vaccine technology and from the compounds licensed from Rutgers and Texas
A&M and other products that it may acquire or develop.

The Company's ability to achieve profitability depends upon, among other things,
its ability to develop products, obtain regulatory approval for its proposed
products, and enter into agreements for product development, manufacturing and
commercialization. The Company's M-Vax(TM) product does not currently generate
revenue and the Company does not expect to achieve revenues from this or other
products for the foreseeable future. Moreover, there can be no assurance that
the Company will ever achieve significant revenues or profitable operations from
the sale of M-Vax(TM) or any other products that it may develop.
    

PLAN OF OPERATION

   
The Company is currently engaged in the development and commercialization of
biotechnology and pharmaceutical products and technologies. In November 1995,
the Company acquired the rights to the AC Vaccine technology pursuant to the TJU
License. The Company initially intends to be engaged primarily in the
development and commercialization of the AC Vaccine technology, as well as the
potential anti-cancer and anti-infective technology licensed pursuant to the
Rutgers License and the potential anti-cancer technology licensed pursuant to
the Texas A&M License. See "Business." The Company anticipates that during the
next 12 months it will conduct substantial research and development of the AC
Vaccine technology, including, without limitation, Phase III clinical trials on
M-Vax(TM), the Company's lead AC Vaccine technology for metastatic melanoma. The
Company also anticipates that it will expend substantial resources on the
research and development of that same technology for the treatment of other
cancers, which may include ovarian, breast, prostate, lung and colorectal cancer
and acute myologenous leukemia (AML). For example, the Company is in the
preliminary stages of enrolling patients for its Phase II clinical trial of
O-Vax(TM), its AC Vaccine for ovarian cancer. This trial is being conducted at
TJU under the direction of Dr. David Berd. It is also expected that during the
next 12 months, in order to support these clinical trial efforts, the Company
will be required to expend substantial resources on the establishment of
laboratory facilities for the manufacture of its products. See
"Business--Technology Applications and Product Candidates," "Research and
Development." 
    

In connection with the Company's strategy to acquire, develop and commercialize
other potential biotechnology products and technologies, in December 1996, the
Company acquired the exclusive worldwide rights to a series of compounds for the
potential treatment of cancer and other infectious diseases from Rutgers.
Additionally, in February 1997, the Company acquired the exclusive worldwide
rights to another series of compounds for the potential treatment of cancer from
Texas A&M. Pursuant to the Rutgers License and the Texas A&M License, the
Company intends to expend substantial resources on the research and development
of these compounds.

While there can be no assurance, the Company may acquire additional products and
technologies during the next 12 months, which may or may not be in the cancer
immunotherapy field. Should the Company acquire such additional products or
technologies, it is anticipated that such additional products or technologies
will require substantial resources for research, development and clinical
evaluation. However, there can be no assurance that the Company will be able to
obtain the additional financing necessary to acquire and develop such additional
products and technologies. In addition, there can be no assurance, that changes
in the Company's research and development plans or other changes which would or
could alter the Company's operating expenses will not require the Company to
reallocate funds among its planned activities and curtail

                                       21

<PAGE>




certain planned expenditures. In such event, the Company may need additional
financing. There can be no assurance as to the availability or the terms of any
required additional financing, when and if needed. In the event that the Company
fails to raise any funds it requires, it may be necessary for the Company to
significantly curtail its activities or cease operations.

   
During the past 12 months, the Company hired five new employees and it
anticipates that over the next 12 months it may hire approximately two more new
employees, and may establish lab facilities for the clinical development and
manufacture of the AC Vaccine products or any other technologies which may have
been, or may be, acquired. The timing and cost of hiring any additional
employees or the establishment of any such facility may vary depending on need
and cannot currently be predicted with any certainty. 
    

LIQUIDITY AND CAPITAL RESOURCES

The Company currently anticipates that its current resources should be
sufficient to fund operations for approximately the next 24-36 months based upon
the Company's current operating plan and the Company does not currently expect
to be required to raise additional capital in the next 12 months. However, since
the Company's working capital requirements will depend upon numerous factors,
including, without limitation, progress of the Company's research and
development programs, preclinical and clinical testing, timing and cost of
obtaining regulatory approvals, changes in levels of resources that the Company
devotes to the development of manufacturing and marketing capabilities,
competitive and technological advances, status of competitors, and the ability
of the Company to establish collaborative arrangements with other organizations,
there can be no assurance that the Company will be able to meets its business
objectives under its current operations plan and/or not need to raise additional
capital. Since the Company has no committed external sources of capital, and
expects no product revenues for the foreseeable future, it will likely require
additional financing to fund future operations. There can be no assurance,
however, that the Company will be able to obtain the additional funds it will
require on acceptable terms, if at all. If adequate funds are not available the
Company may be required to delay, reduce the scope of or eliminate one or more
of its research or development programs; to obtain funds through arrangements
with collaborative partners or others that may require the Company to relinquish
rights to certain technologies, product candidates or products that the Company
would otherwise seek to develop or commercialize itself; or to license the
rights to such products on terms that are less favorable to the Company that
might otherwise be available. See "Risk Factor--Accumulated Deficit; Uncertainty
of Future Profitability."

                                    BUSINESS
GENERAL

AVAX Technologies, Inc. ("AVAX" or the "Company"), is a development stage
biopharmaceutical company which intends to acquire rights to, and to develop,
technologies and products for the treatment of cancer and other life-threatening
diseases. The Company initially intends to focus its efforts primarily on the
development of immunotherapies and chemotherapies for cancer. Immunotherapy is a
rapidly developing segment of the cancer therapeutic market.

The Company has licensed (the "TJU License") from Thomas Jefferson University
("TJU") an issued U.S. patent and certain patent applications covering a process
for the modification of a patient's tumor cells into a cancer vaccine. This
process allows the Company to produce an autologous cell vaccine (an "AC
Vaccine") that attempts to stimulate the patient's immune system to eliminate
the cancer. This technology has emerged from research conducted at TJU and
primarily involves the removal of a patient's own tumor cells, conjugating them
to a small molecule known as a hapten, and reintroducing the product back into
the patient. The approach is based on the premise that a patient's immune
response to a strongly immunogenic, hapten-conjugated tumor antigen may be
followed by the development of an immune response to the unmodified tumor
antigen, somewhat analogous to the phenomenon of drug-induced autoimmune
disease.

   
The Company's initial AC Vaccine, M-Vax(TM), is currently undergoing
physician-sponsored human clinical trials based on an experimental protocol at
TJU as an outpatient, post-surgical, adjunct therapy for the treatment of
melanoma, and is believed by the Company to be the first therapeutic cancer
vaccine to show a substantial increase in the survival rate for patients with
stage 3 melanoma. In such ongoing clinical trials at TJU, over 275 melanoma
patients have been treated post- surgically on an outpatient basis with
M-Vax(TM). In 62 patients with stage 3 melanoma in protocols in which there has
been sufficient time for long-term follow-up, the five-year survival rate is
approximately 60%. This compares with the historical and control group stage 3
survival rate of approximately 20%, and the survival rate for treatment with
high dose alpha interferon of approximately 32% in stage 3 patients whom the
Company believes to be comparable to those treated with M-Vax(TM). The Company
believes that the results to date of the ongoing clinical trial represent the
first substantial increase in survival for stage 3 melanoma patients treated by
immunotherapy. In the over 275 patients treated in studies, the Company believes
that only relatively minor side effects, such as soreness and swelling at the
site of the application of the M-Vax(TM) vaccine, have been witnessed to date.

The Company also believes that the AC Vaccine technology may have applications
in the treatment of other cancers, which may include ovarian, breast, prostate,
lung and colorectal cancers and acute myologenous leukemia (AML). The Company
intends to fund the preclinical and initial clinical development of this
technology for at least some of these indications. Accordingly, in addition to
continuing the clinical work on M-Vax(TM), the Company has also entered into a
sponsored research agreement with TJU relating to the development of additional
immunotherapies based on the AC Vaccine technology. For example, the Company is
in the preliminary stages of enrolling patients for its Phase II clinical trial
of O-Vax(TM), its AC Vaccine for ovarian cancer. This trial is being conducted
at TJU under the direction of Dr. David Berd, the inventor of the AC Vaccine
technology. 
    

In order to contain costs, the Company may continue to use sponsored research
agreements and contract research organizations to help it develop its
technologies. At the appropriate time the Company may seek corporate partners to
provide the necessary resources and expertise for clinical development and to
market and distribute products. In addition, the Company may seek to explore the
acquisition and subsequent development and commercialization of additional
commercially promising immunotherapy, chemotherapy and adjuvant technologies. No
assurance can be given that the Company will have the requisite resources or
that any such projects will be identified on terms favorable to the Company, if
at all.

In connection with the Company's strategy to acquire, develop and commercialize
other potential biotechnology products and technologies, the Company recently
licensed from Rutgers University and the University of Medicine and Dentistry of
New Jersey (collectively, "Rutgers"), certain patent applications relating to a
series of compounds for the potential treatment of cancer and infectious
diseases (the "Rutgers License"), and from The Texas A&M University System
("Texas A&M"), an issued U.S. patent and certain patent applications relating to
a series of compounds for the potential treatment

                                       23

<PAGE>




of cancer (the "Texas A&M License"). The Company intends to expend substantial
resources on the research and development of these compounds.

BACKGROUND AND SCIENTIFIC RATIONALE OF THE AC VACCINE TECHNOLOGY

Cancer is characterized by the uncontrolled growth and spread of abnormal cells
which escape the body's protective immune surveillance system, invade healthy
tissues and destroy normal tissue function and ultimately lead to a person's
death if untreated. Cancers, composed of either solid tumors or blood-borne
cancerous cells, over time tend to spread to other tissues and organs in the
body (metastasis). Cancer may be diagnosed at any stage of the disease, from
very early (best prognosis) to very late (worst prognosis). When cancer is
detected early and has not yet metastasised (spread) to other organs and
tissues, surgical removal of the tumor is often effective. Unfortunately, many
cancers are not discovered until metastatic cancer cells from the primary tumor
have already entered the blood or lymphatic system and established new tumors at
distant sites. These cells, and the tumors they form, are difficult to diagnose
and treat with current technology.

As of 1995, approximately 7.4 million people in the United States were diagnosed
as having cancer. The incidence of cancer continues to increase. The cost to the
health care system of treating these patients is believed to exceed
approximately $104 billion. The Company is aware of estimates that deaths from
cancer will surpass cardiovascular mortality worldwide by the end of the
century.

Although some progress has been made, few effective treatments are available for
most adult solid tumors, which often metastasize and invade other organs before
they are detected. The standard treatment for solid tumors is surgery. While
this treatment is effective in many types of cancers, in cases in which removal
of the tumor is incomplete or in which the tumor has metastasised, the patient's
prognosis is poor. Chemotherapy and radiation therapy are rather crude
treatments since they kill cells indiscriminately, destroying normal as well as
malignant cells, leading to toxic side-effects and thereby limiting the
usefulness of these therapies. A safe, effective treatment for residual and
metastatic disease is clearly needed. Such a treatment, if effective and safe,
would increase patient survival and may, therefore, be widely adopted.

Although, many different types of drugs are used to treat a variety of cancers,
no one drug has been found to be a cure for the disease. Given the need for new
effective treatments for cancer, a drug which may effectively treat cancer could
have a large market potential. Although there can be no assurance, the Company
believes that an AC Vaccine, developed to effectively treat the recurrence of
cancer after surgery, is likely to have a sizable market share. Surgery, in many
cases is the first treatment performed on cancer patients, and if such a
treatment following surgery were to prove broadly applicable and safe, its
market potential could be significant while enabling the health care system to
realize significant overall cost savings due to a reduction in the number of
cases of recurrent disease requiring hospitalization and ongoing clinical and
home care.

Immunotherapy is an emerging cancer treatment modality that the Company believes
shows promise for utilizing a patient's own immune system to recognize and
eliminate cancer cells. There are a number of different types of immunotherapies
such as cytokines, antibodies, activated cell therapy and vaccines currently
under development by third parties. See "Business--Competition." In all cases,
immunotherapies attempt to modulate the body's immune system to contain and
eliminate cancer cells. In concept, immunotherapies should have fewer
side-effects than chemotherapies and should be relatively well-tolerated by the
patient. Thus, although there can be no assurance of success, the Company
believes immunotherapies have the potential to be effective and by reason of
their selectivity, relatively safe anticancer therapeutic agents.

TECHNOLOGY APPLICATIONS AND PRODUCT CANDIDATES

    THE AC VACCINE TECHNOLOGY

The Company's primary proprietary technology is a patented process that allows
the Company to produce an autologous cell vaccine (an "AC Vaccine") that
attempts to stimulate the patient's own immune system to recognize, contain and
eliminate cancer cells. The technology primarily involves the removal of a
patient's own tumor cells, conjugating them to a small molecule known as a
hapten-dinitro phenyl (DNP), and reintroducing the product back into the patient
with an adjuvant, which is an immunological agent that increases the immune
response. Haptenization is the process of conjugating a small molecule to a
larger molecule. The small molecule known as a hapten, is recognized by the
immune system and elicits an immune response against the larger molecule. The
approach is based on the premise that a patient's immune response to a strongly
immunogenic, hapten-conjugated tumor antigen may be followed by the development
of an immune response to the unmodified tumor antigen, somewhat analogous to the
phenomenon of drug-induced autoimmune disease. Therefore, the process of
haptenizing a patient's tumor cells may allow the unhaptenized cancer cells to
be recognized by the body's immune system leading to an immune response against
the patient's tumor cells and their potential elimination from the body.

In practice, the Company's initial therapy would be used as an adjunct to
surgical treatment of tumors. In one proposed model, the surgeon would remove
the patient's tumor and send the cells to the Company where they would be
processed into an AC Vaccine. The vaccine would then be sent to the patient's
oncologist, who would administer the vaccine on an outpatient basis. The
patient's response to the treatment would then be monitored using standard
protocols.

The Company is initially developing this technology for the treatment of
metastatic melanoma but believes that it possibly could have applications in the
treatment of a variety of solid tumors such as ovarian, breast, prostate, lung
and colorectal cancer and may have applications in the treatment of acute
myologenous leukemia (AML).

   
    M-VAX(TM)

GENERAL. The Company's lead product, M-Vax(TM), is a post-surgical treatment for
stage 3 melanoma. Melanoma is a highly malignant tumor that can spread so
rapidly that it can be fatal within months of diagnosis. The incidence of
melanoma is increasing at a faster rate than most other cancers in the United
States, Australia, northern Europe and Canada. Although there are several
causative factors, rising exposure by the general population to UV radiation in
sunlight appears to be the most significant factor behind this increase. With
the incidence growing over 6% annually, melanoma affects over 200,000 people in
the United States, with approximately 34,000 new cases diagnosed in 1995.
    

Melanoma patients may be categorized according to the following staging system:

o Stage 1-- lesion less than 1.5mm thickness and no apparent metastasis

o Stage 2-- lesion greater than 1.5mm thickness and local spreading from primary
cancer site

o Stage 3-- metastasis to regional draining lymph nodes and regional spread from
primary cancer site

o Stage 4--distant metastasis

Surgical excision of the tumor mass and any of the nearby lymph nodes into which
there has been metastasis remains the generally accepted treatment to date for
patients with stage 3 melanoma. However, in many cases survival is restricted by
the inability of surgery to guarantee removal of all the tumor cells. It is
highly possible for the patient to remain with undetected metastasis. Due to its
limited efficacy and highly toxic side-effects, chemotherapy and radiation have
not been widely used in the treatment of these patients. The five-year survival
rate for these patients is believed by the Company to be approximately 20%.
Recently, the FDA approved the use of high doses of alpha interferon for the
post-surgical treatment of melanoma patients. In clinical studies alpha
interferon has demonstrated a five-year survival rate that the

                                       25

<PAGE>




   
Company believes to be approximately 32% in stage 3 patients whom the Company
believes to be comparable to those treated with M-Vax(TM). Thus, the Company
believes that there is a clear need for an effective post-surgical treatment of
stage 3 melanoma patients, one that would contain metastasis and prevent
recurrent disease. 


CLINICAL TRIALS. Dr. David Berd, the inventor of the patented technology
licensed to the Company by TJU, is a clinical oncologist at TJU. Dr. Berd has
been conducting physician-sponsored clinical trials for the treatment of
melanoma using M-Vax(TM) for approximately the past eight years.

In such ongoing clinical trials at TJU, over 275 melanoma patients have been
treated post-surgically on an outpatient basis with M-Vax(TM). In 62 patients
with stage 3 melanoma in protocols in which there has been sufficient time for
long-term follow-up, the five-year survival rate is approximately 60%. This
compares with the historical and control group survival rates of about 20%, and
the survival rate for treatment with high dose alpha interferon of approximately
32% in stage 3 patients whom the Company believes to be comparable to those
treated with M-Vax(TM). The Company believes that the results to date of the
ongoing clinical trial represent the first substantial increase in survival for
stage 3 melanoma patients treated by immunotherapy. In the over 275 patients
treated in studies, the Company believes that only relatively minor side
effects, such as soreness and swelling at the site of the application of the
M-Vax(TM) vaccine, have been witnessed to date.

TJU and Dr. Berd have conducted the ongoing clinical trials at TJU pursuant to
an FDA-approved, physician-sponsored Investigational New Drug Application
("IND"). The Company has recently met with the FDA to discuss the clinical
results obtained with M-Vax(TM), the use of such results in support of the
submission of a Company-sponsored IND to the FDA, and to review its proposed
Phase III program of clinical trials for M-Vax(TM). Depending upon the results
of such clinical trials, it is the Company's intention to use the results of
these Company-sponsored clinical trials along with the results of the clinical
trial conducted at TJU, as the basis for the filing of a New Drug Application
("NDA") for FDA approval to market M-Vax(TM). The Company also may pursue a
similar regulatory approval and commercialization strategy for M-Vax(TM) in
Australia, Canada, Mexico and certain other countries through corporate
partnering strategies, although such strategies have not yet been finalized or
initiated. Denial of any regulatory approvals or any significant delays in
obtaining any of the same, would have a material adverse effect on the Company.

The Company is in the preliminary stages of enrolling patients for its Phase II
clinical trial of O-Vax(TM), its AC Vaccine for ovarian cancer. This trial is
being conducted at TJU under the direction of Dr. Berd.

    TOPOISOMERASE INHIBITORS

The Rutgers License relates to a series of novel anticancer compounds being
prepared and studied under the direction of Professors Edmund La Voie and Leroy
Lui at Rutgers University (the "Rutgers Compounds"). The Rutgers Compounds fall
into three distinct and varied chemical classes, and have been shown to inhibit
topoisomerase I or topoisomerase II activities, depending on the exact
structure. Topoisomerases are key enzymes needed for remolding DNA, a necessary
function for malignant tumor growth. Inhibitors of these enzymes have been
proven to be clinically-useful anticancer therapies. In addition to having
topoisomerase-inhibiting characteristics, some of the Rutgers compounds have
shown activity against fungal as well as parasitic organisms. Both United States
and non-U.S. patents have been filed for the Rutgers Compounds and their
anticancer and anti-infective uses. Although such compounds are in an early
stage of preclinical development, the Company intends to pursue development of
one or more of these compounds. However, there can be no assurance that any such
compounds will ultimately reach a stage of clinical testing or
commercialization. See "Risk Factors--Technological Uncertainty and Early Stage 
of Product Development," "Government Regulation; No Assurance of Product 
Approval" and "Uncertainty Regarding Patents and Proprietary Rights."

    NOVEL ANTI-ESTROGENS

The Texas A&M License relates to a series of novel anticancer compounds (the
"Texas A&M Compounds") being prepared and studied under the direction of
Professor Stephen Safe at Texas A&M University. The activity exhibited by the
Texas A&M Compounds can be classified as anti-estrogen, although they appear to
act indirectly on the estrogen receptor through a novel pathway. Anti-estrogens
have been proven to be clinically-useful anticancer therapies. United States
patents for both the Texas A&M Compounds and their anticancer uses have been
filed. Although non-U.S. patent filings have not yet 
    

                                       26

<PAGE>




   
been made, the Company expects that foreign patent coverage eventually will be
pursued. Although such compounds are in a early stage of preclinical
development, the Company intends to pursue development of one or more of these
compounds. However, there can be no assurance that any such compounds will
ultimately reach a stage of clinical testing or commercialization. See 
"Risk Factors--Technological Uncertainty and Early Stage of Product 
Development," "Government Regulation; No Assurance of Product Approval" 
and "Uncertainty Regarding Patents and Proprietary Rights."



RESEARCH AND DEVELOPMENT

    AUTOLOGOUS CELL VACCINES

In connection with the TJU License, TJU, Dr. Berd, as TJU's principal
investigator, and the Company entered into a Clinical Study and Research
Agreement pursuant to which TJU and Dr. Berd began a research and clinical study
program for the further development of the AC Vaccine technology for additional
cancer targets. In turn, the Company agreed to fund such research as follows:
$220,094 for the first year of the agreement, $220,381 for the second year of
the agreement and at least $100,000 for the third year of the agreement.
Following the third year, the Company is obligated to spend a minimum of
$500,000 per year on the development of the AC Vaccine technology until
commercialized in the United States. If following the third year, the Company
files for FDA approval of a Company-sponsored NDA for the right to market a
product arising from such technology, the Company may elect to spend less than
$500,000 per year on the development of the AC Vaccine technology during the
period of time the NDA is under review by the FDA. If the Company fails to make
such payments in accordance with the terms of the Clinical Study and Research
Agreement, TJU may terminate the agreement and no further research would be
performed thereunder. Termination of the TJU License will have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Risk Factors--Dependence on Licenses and Sponsored Research
Agreements."

    TOPOISOMERASE INHIBITORS
    

In consideration of the license granted to the Company by Rutgers, the Company
has committed to the funding of research for each of the first three years of
the Rutgers License at a rate of $100,000 per year. In addition, the Company is
obligated to spend an aggregate of $200,000 in the first year, $300,000 in the
second year and $500,000 each year thereafter until the first year of commercial
marketing of a product derived from the Rutgers compounds, for the development,
research (including the $100,000 research funding commitment in each of the
first three years), manufacture, regulatory approval, marketing and selling of a
product derived from the Rutgers compounds. If the Company fails to make such
payments in accordance with the terms of the Rutgers License, Rutgers would be
entitled to terminate the agreement and no further research would be performed
thereunder. The termination of the Rutgers License could have a material adverse
effect on the Company. See "Risk Factors--Dependence on Licenses and Sponsored
Research Agreements."

   
It is expected that the research and development effort with respect to these
compounds will be conducted at Rutgers under the direction of Edmond J. LaVoie,
Ph.D., the originator of the technology underlying the Rutgers License. Dr.
LaVoie is Professor of Medicinal Chemistry and Chairman of the Department of
Pharmaceutical Chemistry at Rutgers and has agreed to become a member of the
Company's Scientific Advisory Board. See "Management--Scientific Advisory
Board."

    NOVEL ANTI-ESTROGENS
    

In consideration of the license granted to the Company by Texas A&M, the Company
has committed to the funding of research in the amount of $108,750 for each of
the first three years. In addition, the Company is required to achieve certain
milestones toward development of a licensed product within certain specified
time frames. If the Company fails to make such payments or achieve such
milestones in accordance with the terms of the Texas A&M License, Texas A&M
would be entitled to terminate the agreement and no further research would be
performed thereunder. The termination of the Texas A&M License could have a
material adverse effect on the Company. See "Risk Factors--Dependence on
Licenses and Sponsored Research Agreements."

It is anticipated that the research and development effort with respect to the
potential anti-cancer compounds licensed under the Texas A&M License will be
conducted at Texas A&M under the direction of Stephen H. Safe, Ph.D., the
originator of

                                       27

<PAGE>




the technology underlying the Texas A&M License. Dr. Safe is Sid Kyle Professor
of Toxicology at Texas A&M and has agreed to become a member of the Company's
Scientific Advisory Board. See "Management--Scientific Advisory Board."

For fiscal years 1995 and 1996, the Company incurred research and development
expenses of $126,957 and $738,991, respectively. See "Financial Statements."
Although there can be no assurance, the Company intends to spend increasingly
more on research and development in the foreseeable future.

PROPRIETARY RIGHTS

THE TJU LICENSE

Pursuant to the TJU License, the Company has licensed an issued U.S. patent and
certain patent applications covering a process for the modification of a
patient's own tumor cells into a cancer vaccine. The TJU License is a
royalty-bearing license for the rights to such patented vaccine technology, and
provides for certain payments upon the occurrence of certain milestones. As
consideration for the TJU License, the Company paid $10,000 to TJU, and sold
458,243 shares of Common Stock at a price of $.002 per share to each of TJU and
Dr. Berd, representing 7.5% (15% in the aggregate) of the Company's total
outstanding voting securities at the time of issuance.

The Company is obligated to make certain milestone payments to TJU as follows:
$10,000 upon initiation of the first clinical trial that is approved by the FDA
(or comparable international agency), $10,000 upon the first filing of an NDA
with the FDA (or comparable filing with a comparable international agency), and
$25,000 upon receipt by the Company of approval from the FDA (or comparable
international agency) to market products relating to the AC Vaccine technology.
In addition, the Company is obligated to pay royalties on its net sales revenue
and a percentage of all revenues received from sublicenses relating to the AC
Vaccine technology. Failure to comply with the terms of the TJU License may
cause its termination, which would have a material adverse effect on the
Company. See "Risk Factors--Dependence on Licenses and Sponsored Research
Agreements."

THE RUTGERS LICENSE

Pursuant to the Rutgers License, the Company has licensed certain patent
applications relating to a series of compounds for the potential treatment of
cancer and infectious diseases. The Company paid $15,000 as consideration for
the Rutgers License, and has agreed to pay an additional $15,000 license
maintenance fee in each subsequent year. The Company also has agreed to fund
research in the amount of $100,000 for the first three years of the Rutgers
License. The license maintenance fee is not payable in years where research
funding is equal to or greater than $100,000.

The Company has committed to the issuance to Rutgers of warrants to purchase
250,000 shares of Common Stock at a price of $4.12 per share. Such warrants are
exercisable upon the achievement of certain development-related milestones. The
first 150,000 of such warrants will expire in 2006 and the final 100,000 of such
warrants will expire in 2011. These warrants will provide for cashless exercise,
piggyback registration rights and certain anti-dilution rights.

The Company is also obligated to pay certain milestone payments as follows:
$15,000 on the earlier of October 31, 1999 or the date of first filing of an IND
application with the FDA, or comparable international agency, $25,000 on the
earlier of October 31, 2001 or the date of initiation of Phase II trials in the
United States or another major market country, $45,000 on the earlier of October
31, 2005 or the date of first filing of an NDA application with the FDA, or
comparable international agency and $150,000 on the earlier of October 31, 2008
or the date of receipt by the Company of approval from the FDA or comparable
international agency to market products. In addition, the Company is required to
pay royalties on its worldwide net sales revenue derived from the Rutgers
compounds and a percentage of all revenues received from sublicenses of products
derived from these compounds. Failure to comply with the terms of the Rutgers
License may cause its termination, which would have a material adverse effect on
the Company. See "Risk Factors--Dependence on Licenses and Sponsored Research
Agreements."



                                       28

THE TEXAS A&M LICENSE

Pursuant to the Texas A&M License, the Company has licensed an issued U.S.
patent and certain patent applications relating to a series of compounds for the
potential treatment of cancer. Under the terms of the agreement, the Company is
obligated to pay future milestone payments, royalties on its net sales revenue
derived from these compounds and a percentage of all revenues received from
sublicensees of such compounds. The Company also has agreed to fund research in
the amount of $108,750 for each of the first three years of the Texas A&M
License. Failure to comply with the terms of the Rutgers License may cause its
termination, which would have a material adverse effect on the Company. See
"Risk Factors-- Dependence on Licenses and Sponsored Research Agreements."

In the future, the Company may require additional licenses from other parties to
develop, manufacture and market commercially viable products effectively. The
Company's commercial success will depend in part on obtaining and maintaining
such licenses. There can be no assurance that such licenses can be obtained or
maintained on commercially reasonable terms, if at all, that the patents
underlying such licenses will be valid and enforceable or that the proprietary
nature of the patented technology underlying such licenses will remain
proprietary. The Company presently intends to pursue aggressively the broadest
patent coverage possible for all of its intellectual property. See "Risk
Factors--Uncertainty Regarding Patents and Proprietary Rights."

COMPETITION

The Company is aware of estimates that more than 300 companies are reported to
have approximately 1,250 cancer drugs under development worldwide, of which a
substantial number are under development in the United States. Many of such
drugs or other substances under development involve chemotherapeutic agents and
cancer immunotherapies and, thus, are, or may be, in direct competition with the
Company's AC Vaccine or compounds resulting from development work pursuant to
the Rutgers License or the Texas A&M License. Such future competitor products
and drugs may perform more effectively or safely than the Company's product
candidates.

Many of the companies engaged in anticancer research and development and in
acquiring rights to the products of such research and development, including
biotechnology companies, have substantially greater financial, technical,
scientific, manufacturing, marketing and other resources than the Company and
have more experience in developing, marketing and manufacturing therapeutics,
including performing the preclinical testing and clinical trials that are
required for obtaining FDA and other regulatory approvals. Included among the
Company's competitors are: (i) large established pharmaceutical companies with
commitments to oncology or antiviral research, development and marketing; (ii)
smaller biotechnology companies with similar strategies; and (iii) many
development stage companies licensing and/or developing oncology therapeutics.

In addition, many research institutes, hospitals and universities are working to
develop products and processes in the same field of cancer that may in the
future be in direct competition with the Company's present and future products.

Several companies or research institutions are developing cancer vaccines to
treat melanoma, including several which are in Phase III clinical trials. The
principal competitive factors in the area of cancer immunotherapies are (i) the
efficacy of the product and (ii) the timing of the entry of the product into the
market. Although there is significant competition, to date, the Company believes
that none of such immunotherapies have demonstrated the increase in survival
over the same period of time that the Company's technology has shown. Although
there can be no assurance, the Company also believes that its AC Vaccine
technology may be applicable to a variety of solid tumors such as ovarian,
breast, prostate, lung and colorectal cancer and may have applications in the
treatment of acute myologenous leukemia (AML) and therefore may not be as
limited as certain other approaches. With respect to the timing of the entry of
the product, the Company is unable to estimate, when, if at all, any of its
potential products will be approved.

                                       29

MANUFACTURING AND MARKETING

The Company does not currently have the resources to manufacture or directly
market any products that it may develop. In connection with its research and
development activities, the Company may seek to enter into collaborative
arrangements with pharmaceutical, medical device, health care, chemical or other
companies to assist in further funding as well as in development, manufacturing
and/or marketing of its products if such activities are commercially feasible.
These partners may also be responsible for commercial scale manufacturing, which
may be subject to compliance with applicable FDA regulations. The Company
anticipates that such arrangements may involve the grant of exclusive or
semi-exclusive rights to sell specific products to specified market segments or
particular geographic territories in exchange for a royalty, joint venture,
future co-marketing or other financial interests.

To date, the Company has not entered into any collaborative commercial
manufacturing or marketing agreements for any of its potential products. There
can be no assurance that the Company will be able to enter into any such
arrangements on favorable terms, if at all. Such collaborative marketing
arrangements, whether licenses, joint ventures or otherwise, may result in lower
revenues than would otherwise be generated if the Company conducted the
marketing of their own products. See "Risk Factors--Dependence on Third Parties
for Additional Funds and for Manufacturing, Marketing and Selling."

The Company may elect to establish its own manufacturing facilities for the
products and technologies that it may develop. In the event the Company decides
to establish manufacturing facilities, the Company will be required to hire and
train significant numbers of employees and to comply with the extensive cGMP
regulations applicable to such a facility. The establishment of any such
facilities and eventual expansion of operations to commercial levels, as well as
the hiring of qualified employees, could require substantial expenditures. In
addition, if any of the Company's products produced at its facilities were
regulated as biologics, the Company could be required to file with the FDA in
order to obtain an establishment license (or similar license) for its
facilities. Any delay in the FDA's approval (or its refusal to grant) such a
license would delay or prevent marketing of the relevant product. See "Risk
Factors--Lack of Manufacturing Facilities."

GOVERNMENT REGULATION

The research, preclinical development, clinical trials, product manufacturing
and marketing which may be conducted by the Company is subject to regulation by
the FDA and similar health authorities in foreign countries. The proposed
products and technologies of the Company also may be subject to certain other
federal, state and local government regulations, including, without limitation,
the Federal Food, Drug and Cosmetic Act, and their state, local and foreign
counterparts. Although there can be no such assurance, the Company does not
believe that compliance with such laws and regulations has, nor is presently
expected to have, a material adverse effect on the business of the Company.
However, the Company cannot predict the extent of the adverse effect on its
business or the financial and other cost that might result from any government
regulations arising out of future legislative, administrative or judicial
action. See "Risk Factors--Government Regulation; No Assurance of Product
Approval."

   
Generally, the steps required before a pharmaceutical or therapeutic biological
agent may be marketed in the United States include: (i) preclinical laboratory
tests, IN VIVO preclinical studies in animals, toxicity studies and formulation
studies; (ii) the submission to the FDA of an IND application for human clinical
testing, that must become effective before human clinical trials commence; (iii)
adequate and well-controlled human clinical trials to establish the safety and
efficacy of the drug; (iv) the submission of an NDA to the FDA; and (v) the FDA
approval of the NDA prior to any commercial sale or shipment of the drug. In
addition to obtaining FDA approval for each product, each domestic drug
manufacturing establishment must be registered with, and approved by, the FDA.
Domestic manufacturing establishments are subject to biennial inspections by the
FDA and must comply with Good Manufacturing Practices ("GMP") for both drugs and
devices. To supply products for use in the United States, foreign manufacturing
establishments must comply with GMP and are subject to periodic inspection by
the FDA or by corresponding regulatory agencies in such countries under
reciprocal agreements with the FDA. As permitted by FDA regulations, the
M-Vax(TM) human clinical trials are being conducted by TJU under the supervision
of Dr. David Berd. Even if the Company eventually receives FDA approval of an
NDA to 
    

                                       30

<PAGE>




   
commercialize any of its products, there can be no assurance that the Company
will be able to successfully manufacture such product at a commercially
acceptable cost. 
    

For clinical investigation and marketing outside the United States, 
the Company also is subject to foreign regulatory requirements governing
human clinical trials and marketing approval for drugs. The requirements
governing the conduct of clinical trials, product licensing, pricing and
reimbursement vary widely for European countries both within and outside the
European Community ("EC"). Outside the United States, the Company's ability to
market a product is contingent upon receiving a marketing authorization from the
appropriate regulatory authority. At present, foreign marketing authorizations
are applied for at a national level, although within the EC certain registration
procedures are available to companies wishing to market their products in more
than one EC member state. If the regulatory authority is satisfied that adequate
evidence of safety, quality and efficacy has been presented, a marketing
authorization will be granted. The system for obtaining marketing authorizations
within the EC registration system is a dual one in which certain products, such
as biotechnology and high technology products and those containing new active
substances, will have access to a central regulatory system that provides
registration throughout the entire EC. Other products will be registered by
national authorities in individual EC member states, operating on a principle of
mutual recognition. This foreign regulatory approval process includes, at least,
all of the risks associated with FDA approval set forth above. The Company could
possibly have greater difficulty in obtaining any such approvals and also might
find it more difficult to protect its intellectual property abroad.


SOURCES AND AVAILABILITY OF RAW MATERIALS AND THE NAMES OF PRINCIPAL SUPPLIERS

   
The Company does not expect to encounter significant difficulties in obtaining
raw materials for M-Vax(TM) since it is primarily composed of a readily
available chemical reagent, DNP, and the patient's own tumor cells. Should the
supply of DNP significantly decrease, the Company may encounter problems
preparing M-Vax(TM). 
    

COMPLIANCE WITH ENVIRONMENTAL LAWS

The Company's business may be subject to regulation under federal, state, local,
and foreign laws regarding environmental protection and hazardous substance
control. The Company believes that its compliance with these laws will have no
adverse impact upon its capital expenditures, earnings or competitive position.
Federal, state and foreign agencies and legislative bodies have expressed
interest in the further environmental regulation of the biotechnology industry.
The Company is unable to estimate the extent and impact of such, if any, future
federal, state, local legislation or administrative environmental action.

EMPLOYEES

   
As of April 1, 1997, the Company had five full-time employees, including Jeffrey
M. Jonas, M.D., its President and Chief Executive Officer, David L. Tousley,
C.P.A., its Chief Financial Officer, and Ernest W. Yankee, Ph.D., its Executive
Vice President. It has seven other consultants, scientific advisors, part-time
officers and directors who devote only a portion of their time to the business
of the Company. The Company believes that it maintains good relations with Dr.
Jonas and its employees, consultants, scientific advisors, part-time officers
and directors. See "Risk Factors--Lack of Management and Employees" and
"--Dependence Upon Key Personnel and Consultants." 
    

FACILITIES

The Company's executive offices are located at 4520 Main, Suite 930, Kansas
City, Missouri 64111. The Company anticipates that in the future it may own or
lease its own laboratory facility for the manufacturing of its potential
products although no such lease or ownership interest is under current
consideration. The research and development work of the Company is currently
being conducted at TJU, Rutgers and Texas A&M pursuant to their respective
license agreements with the Company. See "Risk Factors--Lack of
Facilities,""--Dependence on Third Parties for Additional Funds and for
Manufacturing, Marketing and Selling," and "--Dependence on Others for Clinical
Development of, Regulatory Approvals for, and Manufacturing and Marketing of
Pharmaceutical Products" and "Certain Transactions."

Drs. Berd and Weisbach are compensated pursuant to their consulting agreements
with the Company. See "Employment Agreements, Termination and Severance
Arrangements." It is expected that the other scientific advisors will enter into
Scientific Advisory Board agreements pursuant to which they may be compensated
on a per meeting basis and otherwise as shall be determined by the Board of
Directors (or the Compensation Committee).

Members of the Scientific Advisory Board may be employed by or have consulting
agreements with entities other than the Company, some of which may conflict or
compete with the Company, or which may, limit a particular member's availability
to the Company. Certain of the institutions with which the Scientific Advisory
Board members are affiliated may have regulations or policies which are unclear
with respect to the ability of such personnel to act as part-time consultants or
in other capacities for a commercial enterprise. Regulations or policies now in
effect or adopted in the future might limit the ability of the Scientific
Advisory Board members to consult with the Company. The loss of the services of
certain of the Scientific Advisory Board members could have a material adverse
effect on the Company.

Although each of the members of the Scientific Advisory Board has the customary
contractual obligation to keep confidential and not to disclose nor use any
confidential or proprietary information of the Company's, inventions or
processes discovered by any Scientific Advisory Board member, in certain
instances or unless otherwise agreed, will not become the property of the
Company but will remain the property of such person or of such person's
full-time employers. In addition, the institutions with which the Scientific
Advisory Board members are affiliated may make available the research services
of their scientific and other skilled personnel, including the Scientific
Advisory Board members to entities other than the Company. In rendering such
services, such institutions may be obligated to assign or license to a
competitor of the Company patents and other proprietary information which may
result from such services, including research performed by an advisor or
consultant for a competitor of the Company.

Pursuant to a private offering held in May and June 1996, the Company
consummated an offering of Series B Preferred Stock (the "Series B Offering")
pursuant to which the Company raised aggregate gross proceeds of approximately
$25,800,000. In connection with services rendered by Paramount Capital, Inc., as

Offering, and pursuant to a placement agency agreement entered into by the
Company and the Placement Agent, the Company paid the Placement Agent cash
commissions of approximately $2,324,000, a non-accountable expense allowance of
approximately $1,033,000 and placement warrants ("Series B Placement Warrants")
to acquire approximately 25,820 shares of Series B Preferred Stock, exercisable
until June 11, 2006 at an exercise price of $110 per share of Series B Preferred
Stock. See "Description of Securities."

   
Pursuant to the placement agency agreement for the Series B Offering, on June

Agreement, pursuant to which the Placement Agent will act as the Company's
financial advisor. Such engagement provides that the Placement Agent will

expenses and success fees. 
    

On October 20, 1995, the Company entered into an Engagement & Technology

be deemed an affiliate of both the Company and the Placement Agent, pursuant to
which The Castle Group identified, negotiated and acquired for the Company the
TJU License. In consideration for the conveyance of the license, TJU and Dr.
Berd were both granted and sold 458,243 shares of Common Stock at a price of

On December 27, 1995, the Company sold its former leading product under
development (the "Former Lead Product"), an over-the-counter nutritional
dietary, medicinal and/or elixorative food supplement or drug and related
patents and intellectual property to a subsidiary of Interneuron
Pharmaceuticals, Inc. ("Interneuron"). In consideration for the Former Lead
Product, Interneuron agreed to pay in two installments, in December 1996 and
December 1997, $2.4 million of its common stock ("IPI Stock") to the Company or
its designees. In the Company's Stockholder Information Statement dated June
15,1995, the IPI Stock was designated, under certain circumstances, to be paid
approximately at the time of each installment to the holders of shares of the
Company's Series A Preferred Stock which were issued and outstanding on December
27, 1995 and to the Company's former President and Chief Executive Officer,
Dayne R. Myers. All shares of Series A Preferred Stock were automatically
converted in accordance with their terms into shares of Common Stock effective
June 11, 1996, the date of the final closing of the Series B Offering. The IPI
Stock remained payable to those persons who were record holders of shares of the
Company's Series A Preferred Stock on December 27, 1995. Accordingly, in January
1997, 55,422 shares of IPI common stock were distributed to the former holders
of Series A Preferred Stock and Dayne Meyers as the first installment payment.
The transactions relating to the sale of Former Lead Product and the rights of
the former holders of the shares of Series A Preferred Stock to the IPI Stock
were approved by action by written consent of the Board of Directors of the
Company and the holders of a majority of the shares of both the Common Stock and
the Series A Preferred Stock, voting separately as a class in July 1995. Based
upon publicly available information, Interneuron is a diversified
biopharmaceutical company engaged in the development and commercialization of a
portfolio of products primarily for the treatment or management of central
nervous systems disorders. Interneuron's common stock is traded on the Nasdaq
National Market. The market price of Interneuron's common stock at December 31,
1995, and April 3, 1997 was $12.50 and $17.125, respectively.

LLC. Dr. John K.A. Prendergast, also a Director of the Company, is a Managing

                            DESCRIPTION OF SECURITIES

The Company is authorized to issue up to 50,000,000 shares of Common Stock, par
value $.002 per share, and 5,000,000 shares of preferred stock, par value, $.01
per share, of the Company. As of February 15, 1997, 6,222,316 shares of Common
Stock and 259,198 shares of Series B Preferred Stock were issued and
outstanding.

COMMON STOCK

Each holder of Common Stock of the Company is entitled to one vote for each
share held of record. There is no right to cumulative voting of shares for the
election of directors. The shares of Common Stock are not entitled to preemptive
rights and are not subject to redemption or assessment. Each share of Common
Stock is entitled to share ratably in distributions to shareholders and to
receive ratably such dividends as may be declared by the Board of Directors out
of funds legally available therefor. Upon liquidation, dissolution or winding up
of the Company, the holders of Common Stock are entitled to receive, pro-rata,
the assets of the Company which are legally available for distribution to
shareholders. The issued and outstanding shares of Common Stock are validly
issued, fully paid and non-assessable.

PREFERRED STOCK

   
The Company is authorized to issue up to 5,000,000 shares of preferred stock,
par value $.01 per share (of which 300,000 are designated as Series B Preferred
Stock and 259,198 of which are issued and outstanding). The preferred stock of
the Company can be issued in one or more series as may be determined from
time-to-time by the Board of Directors. In establishing a series the Board of
Directors shall give to it a distinctive designation so as to distinguish it
from the shares of all other series and classes, shall fix the number of shares
in such series, and the preferences, rights and restrictions thereof. All shares
of any one series shall be alike in every particular. The Board of Directors has
the authority, without shareholder approval, to fix the rights, preferences,
privileges and restrictions of any series of preferred stock including, without
limitation: (a) the rate of distribution, (b) the price at and the terms and
conditions on which shares shall be redeemed, (c) the amount payable upon shares
for distributions of any kind, (d) the terms and conditions on which shares may
be converted if the shares of any series are issued with the privilege of
conversion and (e) voting rights except as limited by law.
    

Although the Company currently does not have any plans to issue additional
shares of preferred stock or to designate a new series of preferred stock, there
can be no assurance that the Company will not do so in the future. As a result,
the Company could authorize the issuance of a series of preferred stock which
would grant to holders preferred rights to the assets of the Company upon
liquidation, the right to receive dividend coupons before dividends would be
declared to holders of Common Stock, and the right to the redemption of such
shares, together with a premium, prior to the redemption to Common Stock. The
current shareholders of the Company have no redemption rights. In addition, the
Board could issue large blocks of voting stock to fend off unwanted tender
offers or hostile takeovers without further shareholder approval.

SERIES A PREFERRED STOCK

At one time, the Company had designated and issued 1,287,500 shares of Series A
Preferred Stock, par value $.01 per share ("Series A Preferred Stock"). Pursuant
to an automatic conversion provision in the Certificate of Designations
therefor, all outstanding shares of Series A Preferred Stock were converted into
an aggregate of 643,750 shares of Common Stock effective as of June 11, 1996, in
connection with the second closing of the Series B Offering. Thereafter, in July
1996, the Series A Preferred Stock was eliminated pursuant to a Certificate of
Elimination filed by the Company. Notwithstanding such conversion, holders of
the Series A Preferred Stock at the time of such conversion, will receive, pro
rata, $2.4 million of shares of common stock of IPI. The first installment of
common stock of IPI was received by these former holders of Series A Preferred
Stock in January 1997. See "Certain Transactions."

SERIES B PREFERRED STOCK

The Board of Directors of the Company has authorized the issuance of up to
300,000, of which 259,198 are outstanding, shares of Series B Preferred Stock,
par value $.01 per share, the rights, preferences and characteristics of which
are as follows:

    DIVIDENDS

The holders of Series B Preferred Stock are entitled to receive dividends as,
when and if declared by the Board of Directors of the Company out of funds
legally available therefor. No dividend or distribution, as the case may be,
will be declared or paid on any junior stock unless the dividend also is paid to
holders of the Series B Preferred Stock. The Company does not intend to pay cash
dividends on the Series B Preferred Stock or the underlying Common Stock for the
foreseeable future.

    CONVERSION

Each share of Series B Preferred Stock may be converted, in whole or part, at
the option of the holder at any time after the initial issuance date into 50
shares of Common Stock based upon an initial conversion price of $2.00 per share
of Common Stock (the "Initial Conversion Price"). The Initial Conversion Price
is subject to adjustment upon the occurrence of certain mergers,
reorganizations, consolidations, reclassifications, stock dividends or stock
splits which will result in an increase or decrease in the number of shares of
Common Stock outstanding. In addition, the Initial Conversion Price is subject
to adjustment on June 11, 1997 (the "Reset Date"), if the average daily trading
price of the Common Stock for the 30 consecutive trading days immediately
preceding the Reset Date (the "Twelve Month Trading Price") is less than 135% of
the then applicable Initial Conversion Price ("Reset Event"). Upon a Reset
Event, the then applicable Initial Conversion Price will be reduced to equal the
greater of (i) the Twelve Month Trading Price divided by 1.35 and (ii) 50% of
the then applicable Initial Conversion Price.

    MANDATORY CONVERSION

The Company has the right at any time after the Reset Date to cause the
Preferred Stock to be converted in whole or in part, on a PRO RATA basis, into
shares of Common Stock if the closing price of the Common Stock exceeds 150% of
the then applicable Preferred Conversion Price for at least 20 trading days in
any 30 consecutive trading day period.

    LIQUIDATION

Upon (i) a liquidation, dissolution or winding up of the Company, whether
voluntary or involuntary, (ii) a sale or other disposition of all or
substantially all of the assets of the Company or (iii) merger or consolidation
(a "Merger Transaction") in which the Company is not the surviving entity and
shares of Common Stock consisting in excess of 50% of the voting power of the
Company are exchanged (subparagraphs (i), (ii), and (iii) being collectively
referred to as a "Liquidation Event"), after payment or provision for payment of
the debts and other liabilities of the Company, the holders of the Preferred
Stock then outstanding will first be entitled to receive, pro rata (on the basis
of the number of shares of the preferred stock then outstanding), and in
preference to the holders of the Common Stock and any other series of Preferred
Stock of the Company, an amount per share equal to $135.00 plus accrued but
unpaid dividends, if any; provided, however, that in the case of a Merger
Transaction, such $135.00 per share may be paid in cash and/or securities of the
surviving entity in such Merger Transaction.

    VOTING RIGHTS

The holders of the Series B Preferred Stock have the right at all meetings of
stockholders to the number of votes equal to the number of shares of Common
Stock issuable upon conversion of the Series B Preferred Stock at the record
date for determination of the stockholders entitled to vote. So long as 50% of
the shares of Series B Preferred Stock remain outstanding, the holders of 66.67%
of the Series B Preferred Stock are entitled to approve (i) the issuance of any
securities of the Company senior to or on parity with the Series B Preferred
Stock, (ii) any alteration or change in the rights or

                                       44

<PAGE>




preferences or privileges of the Series B Preferred Stock and (iii) the
declaration or payment of any dividend on any junior stock or the repurchase of
any securities of the Company. Except as provided above or as required by
applicable law, the holders of the Series B Preferred Stock will be entitled to
vote together with the holders of the Common Stock and not as a separate class.

LOCK-UP AGREEMENTS

   
The holders of shares of Common Stock issuable upon conversion of shares of
Series B Preferred Stock (the "Conversion Shares") agreed pursuant to their
subscription agreements with the Company not to offer, pledge, sell, contract to
sell, grant any option for the sale of, or otherwise dispose of, directly or
indirectly, 75% of the Conversion Shares, without the prior written consent of
the placement agent in the Series B Offering (the "Lock-Up"). Such restrictions
were effective as follows: (i) with respect to 75% of the Conversion Shares
until September 12, 1996 (three months after the completion of the Series B
Offering); with respect to the 50% of the Conversion Shares until December 12,
1996 (six months after the completion of the Series B Offering); and with
respect to the remaining 25% of the Conversion Shares until March 11, 1997 (nine
months after the completion of the Series B Offering). Accordingly, 25% of each
of the holders' Conversion Shares were never subject to the Lock-Up, and as of
March 11, 1997, the Lock-Ups expired.

However, holders of approximately 94% of the shares of Series B Preferred Stock
agreed to amend their subscription agreements with the Company to extend the
Lock-Up period. Pursuant to this amendment, the Lock-Up for such holders' shares
of Series B Preferred Stock has been extended to be in effect as follows: (i)
three months following the later of the effectiveness under the Securities Act
of 1933 of the Registration Statement ("Effectiveness") and the listing of the
Conversion Shares on a national securities exchange or initial quotation on the
Nasdaq SmallCap Market ("Listing"), with respect to 75% of the Conversion
Shares; (ii) six months following the later of Effectiveness and Listing with
respect to 50% of the Conversion Shares and (iii) nine months following the
later of Effectiveness and Listing with respect to the remaining 25% of the
Conversion Shares. Accordingly, 25% of such holders' Conversion Shares continue
to have never been subject to the Lock-Up. The Conversion Shares of holders that
have not agreed to amend their subscription agreement are not subject to any
Lock-Up.

In consideration of the agreement with the Company to extend the Lock-Up period
for their Conversion Shares, holders of shares of Series B Preferred Stock that
agreed to such extended Lock-Up have the right one year after the later of
Effectiveness and Listing to have the Company issue such number of additional
shares of Common Stock as shall be necessary to effect the principles of the
original reset provisions contained in the Certificate of Designations for the
Series B Preferred Stock taking into account any adjustments which may have been
previously made at the time of the Reset Date. 
    

The holders of shares of Series B Preferred Stock issuable upon exercise of
Series B Placement Warrants and the Common Stock issuable upon conversion
thereof (collectively, the "Placement Conversion Shares") are bound, pursuant to
the terms of such Series B Placement Warrants, not to offer, pledge, sell,
contract to sell, grant any option for the sale of, or otherwise dispose of,
directly or indirectly, any of the Placement Conversion Shares prior to June 11,
1997.

   
In addition, the officers and directors of the Company, and certain employees of
Paramount and its affiliates, have agreed to lock-up all securities and
derivative securities of the Company held by such individuals for a period of
two years from the later of Effectiveness and Listing. 
    

1992 STOCK OPTION PLAN

A total of 875,000 shares of Common Stock has been reserved for issuance under
the Company's 1992 Stock Option Plan (the "AVAX Option Plan"). The AVAX Option
Plan was adopted by the Board of Directors in April 1992 and approved by
stockholders of the Company in April 1992. The AVAX Option Plan expires by its
own terms in 2002.

The AVAX Option Plan provides for the grant of "incentive stock options" within
the meaning of Section 422 of the Internal Revenue Code of 1986, as amended, and
nonqualified stock options to employees, directors and consultants of the
Company. Incentive stock options may be granted only to employees. The AVAX
Option Plan is administered by the Board

                                       45

<PAGE>




of Directors of the Company (or a Committee thereof) which determines the terms
of the options granted, including the exercise price, the number of shares
subject to the option, and the schedule on which the option becomes exercisable.

The AVAX Option Plan requires that the exercise price of incentive stock options
must be at least equal to the fair market value of such shares on the date of
grant and that the exercise price of nonqualified stock options, after the
Common Stock becomes publicly traded, must be at least equal to the fair market
value of such shares on the date of grant. The maximum terms of options granted
under the AVAX Option Plan is 10 years. With respect to any participant who owns
stock possessing more than 10% of the voting rights of outstanding capital
stock, the exercise price of any option must be at least equal to 110% of fair
market value on the date of grant and the term may be no longer than five years.
No incentive stock option may be granted under the AVAX Option Plan to any
individual if the aggregate fair market value of the shares (determined as of
the time of the option is granted) which would become exercisable during any
calendar year, under all incentive stock options held by such individual,
exceeds $100,000, unless such excess options shall be treated as nonstatutory
stock options.

Generally, any option held by an individual who ceases to be employed or
retained by the Company may be exercised by such individual within three months
after such individual ceases to be employed or retained by the Company or within
one year after such individual ceases to be employed or retained in the case of
disability. Generally, any option held by an individual who dies while still
employed or retained by the Company or dies within three months after the date
he or she is no longer employed or retained by the Company may be exercised by
such individual's representative within six months following the date of death.

   
Pursuant to the AVAX Option Plan, as of April 1, 1997, options to purchase
60,000 shares of Common Stock were outstanding (of which approximately 52,222
were vested) at a weighted average price of $0.60 per share, and no options had
been exercised. 
    

Such options do not confer upon holders thereof any voting or any other rights
of a stockholder of the Company. The shares of Common Stock issuable upon
exercise of the options and warrants in accordance with the terms thereof, will
be fully paid and nonassessable.

OTHER OPTIONS

   
Pursuant to their letters of employment with the Company, Dr. Jonas, Mr.
Tousley, Dr. Yankee and one other employee of the Company received share options
to acquire 637,745, 250,000, 250,000 and 5,000 shares of Common Stock,
respectively, at an exercise price of $.50 per share. One other employee of the
Company has received share options to purchase 105,000 shares of Common Stock at
an exercise price equal to $3.50. All such share options will vest at a rate of
1/16 per quarter over the four-year period following the effective date of their
respective letters of employment and are exercisable for a period of seven
years.

be exercised in whole or in part over a seven-year period.
    

Each of the foregoing warrants contain provisions that generally provide the
holders thereof certain antidilution protection in certain events (such as, but
not limited to, the occurrence of stock dividends, stock splits, mergers, sales
of all or

substantially all of the Company's assets and sales of other preferred stock at
below market price) by adjustment of the applicable exercise price and/or the
number of shares issuable upon exercise of such warrants.

The Company is not required to issue fractional shares of Common Stock upon
exercise of any such warrants. In lieu thereof, an amount of cash equal to the
same fraction of the then current market value of a share of Common Stock will
be paid. No adjustment as to dividends will be made upon any exercise of any
such warrants. The holder of any such warrant will not have any rights as a
holder of Common Stock unless and until the applicable warrant is exercised.

REGISTRATION RIGHTS

The Company has agreed under certain circumstances to register the shares of
Common Stock owned by TJU, Dr. Berd, VentureTek, L.P. and, Dr. Rosenwald. Under
terms of the agreements between the Company and the holders of such registrable
securities, generally, if the Company proposes to register any of its securities
under the Securities Act, either for its own account or for the account of other
securityholders exercising registration rights, such holders are entitled to
notice of such registration and are entitled to include such shares of Common
Stock therein. Holders of an aggregate of 50% of the shares of Common Stock
issuable upon exercise of the Series A Placement Warrants are entitled to
exercise their right to have the shares of Common Stock issuable upon exercise
thereof registered under the Securities Act at any time 180 days after the
Company's initial public offering until August 31, 1999. Holders of the Castelli
and Shear/Kershman Warrants are entitled under certain circumstances 18 months
after the Company's initial public offering also to require the Company to file
a registration statement under the Securities Act at the Company's expense with
respect to their shares of Common Stock and the Company is required to use its
reasonable best efforts to effect such registration. Such rights are subject to
certain conditions and limitations, including the right of the underwriter of an
offering of the Common Stock to limit the number of shares included in such
registration in certain circumstances. The holders of the Meyerson Warrants and
holders of any shares of Common Stock issued upon exercise of the Meyerson
Warrants ("Meyerson Shares") are entitled, during the period commencing October
24, 1998, and ending October 24, 2001, upon the request of at least 51% of the
collective holders of the unexercised Meyerson Warrants and the Meyerson Shares,
to require the Company to file a registration statement under the Securities Act
at the Company's expense with respect to the shares of Common Stock issuable
upon exercise of the Meyerson Warrants. Holders of the Meyerson Warrants and
Meyerson Shares are also entitled to certain piggyback registration rights
during the same period. Holders of the Rutgers Warrants, as well as the warrants
issuable to Drs. Wertheimer and Mermelstein, are entitled to piggyback
registration rights in any registrations subsequent to the first public offering
by the Company.

Registered representatives of Paramount that may have had registration rights
with respect to their ownership of shares of Common Stock (including shares of
Common Stock issuable upon conversion of shares of Series B Preferred Stock,
including shares of Series B Preferred Stock issuable upon exercise of any
Placement Warrants), have waived their rights to have such Common Stock included
in the Registration Statement at this time and are not participating in the
Offering.

(1)     Unless otherwise indicated, includes all shares of Common Stock issuable
        upon conversion of the Series B Preferred Stock at the initial
        conversion rate of $2.00 per share. See "Description of
        Securities--Series B Preferred Stock."

(2)     Includes Common Stock issuable upon conversion of the shares of Series B
        Preferred Stock issuable upon exercise of the Series B Placement
        Warrants.

   
(3)     See also footnote 6 to the table set forth under "Principal
        Stockholders."
    

Each Selling Securityholder may, but is not required to, sell all of the shares
of Common Stock shown in the column entitled "Amount of Shares to be Offered"
subject, in certain instances, to lock-up provisions. See "Description of
Securities -- Lock-Up Agreements." The Selling Securityholders and any
broker-dealers that act in connection with the sale of the Common Stock as
principals may be deemed to be "underwriters" within the meaning of Section
2(11) of the Securities Act and any commission received by them and any profit
on the resale of such securities as principals might be deemed to be
underwriting discounts and commissions under the Act. The Selling
Securityholders may agree to indemnify any agent, dealer or broker-dealer that
participates in transactions involving sales of such securities certain
liabilities, including liabilities arising under the Securities Act. The Company
will not receive any proceeds from the sales of the Common Stock by the Selling
Securityholders, although the Company may receive proceeds from the exercise of
the Placement Warrants. Sales of the shares of Common Stock by the Selling
Securityholders, or even the potential sale of such shares, may have an adverse
effect on the market price of the Common Stock.

At the time a particular offer for Common Stock is made, as herein contemplated,
by or on behalf of the Selling Securityholder, to the extent required, a
Prospectus will be distributed by the Selling Securityholder which will set
forth the number of shares of Common Stock being offered and the terms of the
Offering, including the name or names of any underwriters, dealers or agents, if
any, and to the extent that an underwriter is involved, the purchase price paid
by any underwriter for shares purchased from the Selling Securityholder and any
discounts, commissions or concessions allowed or reallowed or paid to dealers.

Except as noted below, none of the Selling Securityholders named in the
preceding table has had any position, office or other material relationship with
the Company or any of its affiliates within the past three years. The Aries
Domestic Fund, L.P. and The Aries Fund, A Cayman Island Trust are private
investment funds managed by Dr. Lindsay A. Rosenwald, a substantial shareholder
and former director of the Company and the sole owner of Paramount. See "Certain
Transactions."

                        SHARES ELIGIBLE FOR FUTURE SALES

   
Upon completion of the Offering, the Company will have 23,252,489 shares of
Common Stock outstanding or issuable upon the conversion of the Series B
Preferred Stock, the exercise of all outstanding or issuable options and
warrants as of the date of this prospectus. Of these shares, the 13,560,598
shares registered in the Offering will be freely tradeable without restriction
or further registration under the Securities Act, except that (i) any shares
purchase by "affiliates" of the Company, as the term is defined under the
Securities Act ("Affiliates"), may generally only be sold in compliance with the
limitations of Rule 144 described below and (ii) that such registered shares may
be subject to certain lock-up provisions discussed below. In addition, the
Company believes that the 905,376 shares of Common Stock may be eligible for
sale without restriction or further registration under the Securities Act,
subject to certain requirements. See "Risk Factors--Potential Adverse Effect of
Shares Eligible For Future Sales." The Company has a Stock Option Plan under
which 875,000 shares of Common Stock have been reserved for issuance, and has
also reserved 1,247,745 shares of Common Stock for issuance pursuant to the
employment arrangements among the Company and Dr. Jonas, Mr. Tousley, Dr. Yankee
and two other non- executive employees. 
    

SALES OF RESTRICTED SHARES
   
The Company believes that 4,305,309 shares of Common Stock are "restricted
securities" and under certain circumstances may, in the future, be sold in
compliance with Rule 144 under the Securities Act, unless they are held by
"affiliates" of the Company (as that term is used under the Securities Act).
Assuming the availability of Rule 144, the Company believes that of the
4,101,358 "restricted" shares of Common Stock, 905,376 shares of Common Stock is
eligible for sale and an additional (i) 1,806,571 shares of Common Stock will be
eligible for sale in 1997 and (ii) 1,593,362 shares of Common Stock will be
eligible in 1998, in each case pursuant to Rule 144, so long as there is
adequate current public information with respect to the Company as contemplated
by Rule 144, as well as, certain volume limitations and manner of sale
requirements imposed by Rule 144.
    
   
In general, under Rule 144 as currently in effect, subject to the satisfaction
of certain other conditions, a person, including an affiliate of the Company,
who beneficially owned restricted shares of Common Stock for at least two years
is entitled to sell, within any three-month period, a number of shares that does
not exceed the greater of one percent of the total number of outstanding shares
of the same class, or the average weekly trading volume of the Common Stock on
the Nasdaq SmallCap Market during the four calendar weeks immediately preceding
the sale. A person who presently is not and who has not been an affiliate of the
Company for at least three months immediately preceding the sale and who has
beneficially owned the shares of Common Stock for at least three years is
entitled to sell such shares under Rule 144(k) without regard to the volume
limitations described above. In addition, the Commission has recently adopted
revisions to Rule 144 and Rule 144(k), the effect of which will be to shorten
the holding period under Rule 144 from two years to one year and to shorten the
holding period under 144(k) from three years to two years. Certain shares
eligible for sale under Rule 144 remain subject to certain lock-up restrictions.
See"Lock-Up Agreements."

Prior to the Offering, there has been only a limited public market for the
Common Stock on the OTC Bulletin Board, and no predictions can be made of the
effect, if any, that the sale or availability for sale of restricted shares or
locked-up shares will have on the market price of the Common Stock on any market
upon which the Common Stock shall be listed. Nevertheless, sales of substantial
amounts of such shares in the public market, or the perception that such sales
could occur, could adversely affect the market price of the Common Stock and
could impair the Company's future ability to raise capital through an offering
of its equity securities.

"Description of Securities--1992 Stock Option Plan," "Other Options," and
"Warrants."

                              PLAN OF DISTRIBUTION

   
A total of 13,560,598 shares of Common Stock are being directly offered for sale
by the Selling Securityholders to the public. The Selling Securityholders may,
but are not required to, sell, directly or through brokers, the shares of Common
Stock in negotiated transactions or in one or more transactions in the market at
the price prevailing at the time of sale. (Certain of the shares of Common Stock
may be subject to lock-up agreements. See "Description of Securities -- Lock-Up
Agreements"). In connection with such sales, the Selling Securityholders and any
participating broker may be deemed to be "underwriters" of the shares of Common
Stock within the meaning of the Securities Act, although the offering of these
securities will not be underwritten by a broker-dealer firm. Sales in the market
may be made to broker-dealers making a market in the Common Stock or other
broker-dealers, and such broker-dealer, upon their resale of such securities,
may be deemed to be "Selling Securityholders" in this offering. The Company will
not receive any of the proceeds from the sale of the Common Stock by the Selling
Securityholders. Pursuant to the terms under which the Preferred Stock and
Placement Warrants were issued and sold, the Company has agreed to indemnify the
Selling Securityholders against such liabilities as they may incur as a result
of any untrue statement of a material fact in the Registration Statement of
which this Prospectus forms a part, or any omission herein or therein to state a
material fact necessary in order to make the statements made, in the light of
the circumstances under which they were made, not misleading. Such
indemnification includes liabilities that the Selling Securityholders may incur
under the Securities Act. 
    

The Company will bear all costs and expenses of the registration under the
Securities Act and certain state securities laws of the Common Stock and any
discounts or commissions payable with respect to sales of such securities.

From time to time, this Prospectus will be supplemented and amended as required
by the Securities Act. During any time when a supplement or amendment is so
required, after notice from the Company, the Selling Securityholders are
required to cease sales until the Prospectus has been supplemented or amended.

The Selling Securityholders have advised the Company that they may sell,
directly or through brokers, all or a portion of the securities offered hereby
in negotiated transactions or in one or more transactions in the market at the
price prevailing at the time of sale. In connection with such sales, the Selling
Securityholders and any participating broker may be deemed to be "underwriters"
of the Common Stock within the meaning of the Securities Act of 1933. It is
anticipated that usual and customary brokerage fees will be paid by the Selling
Securityholders in all open market transactions. The Company will pay all other
expenses of this Offering. See "Plan of Distribution."

   
The Company will inform the Selling Securityholders that the anti-manipulation
provisions of Regulation M promulgated under the Securities Exchange Act of 1934
may apply to the sales of their shares offered hereby. The Company will advise
the Selling Securityholders of the requirement for delivery of this Prospectus
in connection with any sale of the Common Stock offered hereby.
    

Certain Selling Securityholders may from time to time purchase shares of Common
Stock in the open market. These Selling Securityholders have been notified that
they should not commence any distribution of Common Stock unless they have
terminated their purchasing and bidding for Common Stock in the open market as
provided in applicable securities regulations.

                         Report of Independent Auditors

The Board of Directors and Stockholders
AVAX Technologies, Inc.

We have audited the accompanying balance sheet of AVAX Technologies, Inc.
(formerly Walden Laboratories, Inc.) (a development stage company) as of
December 31, 1996, and the related statements of operations, stockholders'
equity (deficit), and cash flows for the years ended December 31, 1995 and 1996,
and for the period from January 12, 1990 (incorporation) to December 31, 1996.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of AVAX Technologies, Inc.
(formerly Walden Laboratories, Inc.) at December 31, 1996, and the results of
its operations and its cash flows for the years ended December 31, 1995 and
1996, and for the period from January 12, 1990 (incorporation) to December 31,
1996, in conformity with generally accepted accounting principles.

1.  DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

DESCRIPTION OF BUSINESS

AVAX Technologies, Inc. (formerly Walden Laboratories, Inc.) (the Company) is a
development stage biopharmaceutical company. The Company changed its name to
AVAX Technologies, Inc. effective March 26, 1996.

In November 1995, the Company sold its leading product under development, an
over-the-counter nutritional, dietary, medicinal and/or elixorative food
supplement or drug and all of the related patents and other intellectual
property (the Product) (see NOTE 2).

Also in November 1995, the Company entered into a license agreement with the
Thomas Jefferson University (TJU) to develop, commercially manufacture and sell
products embodying immunotherapeutic vaccines for the treatment of malignant
melanoma and other carcinomas (the Invention) (see NOTE 3).

In December 1996, the Company entered into a license agreement with Rutgers
University (Rutgers) to develop, commercially manufacture and sell products
embodying a series of compounds for the treatment of cancer and infectious
diseases (the Compounds) (see NOTE 3).

The Company's business is subject to significant risks consistent with
biotechnology companies that are developing products for human therapeutic use.
These risks include, but are not limited to, uncertainties regarding research
and development, access to capital, obtaining and enforcing patents, receiving
regulatory approval, and competition with other biotechnology and pharmaceutical
companies. The Company plans to continue to finance its operations with a
combination of equity and debt financing and, in the longer term, revenues from
product sales, if any. However, there can be no assurance that it will
successfully develop any product or, if it does, that the product will generate
any or sufficient revenues.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reported period.
Actual results could differ from those estimates.

CASH EQUIVALENTS

The Company considers all highly liquid financial instruments with a maturity of
three months or less when purchased to be cash equivalents. At December 31,
1996, substantially all cash and cash equivalents were held in one financial
institution.

MARKETABLE SECURITIES

Management determines the appropriate classification of debt securities at the
time of purchase and reevaluates such designation as of each balance sheet date.
Debt securities are classified as held-to-maturity when the Company has the
positive intent and ability to hold the securities to maturity. Held-to-maturity
securities are stated at amortized cost, adjusted for amortization of premiums
and accretion of discounts to maturity. Such amortization and interest on
securities classified as held-to-maturity are included in interest income.

Equity securities are classified as available-for-sale. Available-for-sale
securities are carried at fair value, with the unrealized gains and losses, net
of tax, reported in a separate component of stockholders' equity. Interest and
dividends on securities classified as available-for-sale are included in
interest income.

SHARE INFORMATION

Prior to the first closing of a private placement on May 15, 1996 (see NOTE 4),
the Company effected a 1-for-2 reverse stock split of the Company's common
stock. All outstanding share amounts included in the accompanying financial
statements have been adjusted to reflect the 1-for-2 reverse stock split.

NET INCOME (LOSS) PER SHARE

Net income (loss) per share is based on net income (loss) divided by weighted
average number of shares of common stock outstanding during the respective
periods, retroactively adjusted to reflect the reverse stock split. The weighted
average number of common shares outstanding have been calculated in accordance
with Staff Accounting Bulletin 83 (SAB 83) of the Securities and Exchange
Commission. SAB 83 requires that shares of common stock, warrants and options
issued one-year prior to the initial filing of a registration statement relating
to an initial public offering at amounts below the public offering price be
considered outstanding for all periods presented in the Company's registration
statement. For purposes of calculating the net income (loss) per share, the
private placement of Series B convertible preferred stock (see NOTE 4) has been
considered to be the equivalent of an initial public offering, and the initial
public offering price was determined to be $1.96 per share by assuming that the
preferred stock issued was immediately converted into common stock. Series A
convertible preferred stock, actually converted in June 1996, was included in
the calculation of the weighted average number of shares for the year ended
December 31, 1995, as if converted.

The weighted average shares used in calculating supplementary net income (loss)
per share include the conversion of Series A preferred stock and the estimated
number of shares assumed to be sold by the Company (641,327 at $1.96 per share)
to repay certain debt of $1,257,000. Net income (loss) per share would have been
$.10 and $(.34) for the years ended December 31, 1995 and 1996, respectively, if
the said shares had been converted/issued at the beginning of the respective
periods.

STOCK-BASED COMPENSATION

In October 1995, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" (SFAS 123). SFAS 123 is effective for fiscal years beginning after
December 31, 1995 and prescribes accounting and reporting standards for all
stock-based compensation plans, including employee stock options, restricted
stock, employee stock purchase plans and stock appreciation rights. SFAS 123
requires compensation expense to be recorded (i) using the new fair value method
or (ii) using existing accounting rules prescribed by Accounting Principles
Board Opinion No. 25, "Accounting for Stock Issued to Employees" (APB 25) and
related interpretations, with pro forma disclosure of what net income and
earnings per share would have been had the Company adopted the new fair value
method. The Company has elected to continue to account for its stock-based
compensation plans in accordance with the provisions of APB 25. Net income
(loss) and related per share amounts determined in accordance with the
provisions of SFAS 123 would not materially differ from amounts reported on the
accompanying statements of operations.

2.  SALE OF THE PRODUCT

In December 1995, the Company entered into an agreement to sell the Product for
$2.4 million in shares of common stock of Interneuron Pharmaceuticals, Inc.
(IPI), a public company, the parent of the purchaser of the Product (the Stock).
Certain common stockholders of the Company are also common stockholders of IPI.
The purchase price, payable in two equal installments in December 1996 and 1997,
is fixed, and the number of shares of Stock will vary depending on the quoted
market price of the Stock at such time.

The first installment was paid on January 3, 1997 in the form of a distribution
of IPI stock directly by IPI to the Series A convertible preferred stockholders,
who were holders of record on the closing date of the agreement for sale, and
the Company's former President and Chief Executive Officer (the Former Officer).
Accordingly, the common stock receivable and the payables to preferred
stockholders and the Former Officer related to both installments are reported as
current assets and liabilities, respectively, in the accompanying balance sheet.

                                      F-12
<PAGE>


2.  SALE OF THE PRODUCT (CONTINUED)

The sale of the Product was approved by the Company's common and Series A
preferred stockholders subject to the following conditions:

     o   At approximately the same time each installment is received by the
         Company, 95.85% of the Stock will be distributed by the Company, or
         directly by IPI, to the Company's preferred stockholders of record
         (referred to herein as the holders of Series A preferred stock) at the
         time sale of the Product closed, on a pro rata basis, to reduce their
         liquidation preference, provided, however, that if at the time of each
         installment, any of the Company's indebtedness which had been
         outstanding at the time of the closing of the agreement to sell the
         Product (December 27, 1995) and is then due and payable, the Company
         will cause such indebtedness to be paid or provided for, whether by use
         of available cash, refinancing, redirecting a portion of the Stock to
         satisfy such indebtedness, or otherwise, as the Company shall determine
         in its best interest.

     o   The remaining 4.15% of the Stock (or a cash payment equal to the value
         thereof) will be distributed to the Former Officer in partial
         consideration for his resignation from the Company and the return to
         the Company of all common stock of the Company and cancellation of
         options to purchase 125,000 shares of common stock (see NOTE 8).

Other than for the Former Officer, none of the other common stockholders were
entitled to any of the Stock.

Because the Stock is receivable in two equal annual installments, the gain from
the sale of the Product, $1,951,000, was calculated by discounting the value of
the Stock receivable using a discount rate of 15%. In 1995, the Company also
recorded the difference between 95.85% of the discounted net present value of
the Stock to be received and the Company's indebtedness, $1,131,744 at December
31, 1995, as a payable to the preferred stockholders of $738,289 to reduce their
liquidation preference. The present value of the amount payable to the preferred
stockholders, including the accretion of interest thereon, is $2,156,106 at
December 31, 1996, since all of the Company's indebtedness outstanding as of the
date of the sale of the Product has been satisfied through sources other than
the Stock to be received (see NOTE 9).

                                      F-13

2.  SALE OF THE PRODUCT (CONTINUED)

The discounted net present value of the Stock distributable to the Former
Officer as of the date of sale, amounting to $80,967, was allocated between
common stock ($445) and severance expense ($80,522) based on the fair value of
the Company's common stock ($.002 per share). The present value of the amount
payable to the Former Officer, including the accretion of interest thereon, is
$93,353 at December 31, 1996.

3.  LICENSE AND RESEARCH AGREEMENTS

In November 1995, the Company entered into an agreement with TJU for the
exclusive worldwide license to develop, manufacture and sell the Invention. The
Company paid cash of $10,000 as consideration for the license agreement. In
addition, the Company sold an aggregate of 916,486 shares of common stock at
$.002 per share (the fair value of the Company's common stock) to TJU and the
scientific founder (the Scientist). These shares have antidilution rights prior
to the first equity financing, as defined in the license agreement, in excess of
$1,000,000 by the Company.

Under terms of the license agreement, the Company is required to raise a minimum
of $500,000 of net operating capital by December 1996. Also under the terms of
the license agreement, (i) the Company is obligated to pay certain milestone
payments as follows: $10,000 upon initiation of the first clinical trial that is
approved by the Food and Drug Administration (FDA) or comparable international
agency, $10,000 upon the first filing of a New Drug Application (NDA) with the
FDA or comparable international agency, and $25,000 upon receipt by the Company
of approval from the FDA or comparable international agency to market products.
In addition, the Company is obligated to pay royalties on its worldwide net
sales revenue derived from the Invention and a percentage of all revenues
received from sublicensees of the Invention.

The Company also entered into a research agreement with TJU to fund a study to
be performed by TJU for the development of the technology related to the
Invention (the Study) at approximately $220,000 per annum for the first three
years. The Company, at its discretion, may reduce the funding in the third year
to no less than $100,000. Following the third year, the Company is obligated to
spend a minimum of $500,000 per

                                      F-14

3.  LICENSE AND RESEARCH AGREEMENTS (CONTINUED)

year on the development of the Invention until commercialized in the United
States. If following the third year, the Company files for United States
marketing approval through a Company sponsored NDA, the Company may elect to
spend less than $500,000 per year on the development of the Invention during the
period of time the NDA is under review by the FDA. The research agreement will
continue until completion of the Study.

In December 1996, the Company entered into an agreement with Rutgers for the
exclusive worldwide license to develop, manufacture and sell products embodying
the Compounds. The Company paid cash of $15,000 as consideration for the license
agreement and has agreed to pay $15,000 in each subsequent year as a license
maintenance fee. The Company has agreed to fund research in the amount of one
hundred thousand dollars ($100,000) per year for the next three years. In
addition, the Company is obligated to spend an aggregate of $200,000 in the
first year, $300,000 in the second year and $500,000 each year thereafter until
the first year of commercial marketing of a product derived from the Compounds.
The license maintenance fee shall not be payable in years where research funding
is equal to or greater than $100,000.

The Company has committed to the issuance of warrants to Rutgers to purchase
250,000 shares of common stock at a price of $4.12 per share based on the
achievement of certain development milestones. The first 150,000 warrants will
expire in 2006 and the final 100,000 warrants will expire in 2011. These
warrants, once issued, shall provide for cashless exercise, piggyback
registration rights and certain antidilution rights.

Under the terms of the license agreement, the Company is obligated to pay
certain milestone payments as follows: $15,000 on the earlier of October 31,
1999 or the date of first filing of an Investigational New Drug (IND)
application with the FDA, or comparable international agency; $25,000 on the
earlier of October 31, 2001 or the date of initiation of Phase II trials in the
United States or another major market country; $45,000 on the earlier of October
31, 2005 or the date of first filing of an NDA application with the FDA, or
comparable international agency; and $150,000 on the earlier of October 31, 2008
or the date of receipt by the Company of approval from the FDA, or comparable
international agency, to market products.

3.  LICENSE AND RESEARCH AGREEMENTS (CONTINUED)

In addition, the Company is obligated to pay royalties on its worldwide net
sales revenue derived from the Compounds and a percentage of all revenues
received from sublicensees of products derived from the Compounds. Such royalty
payments shall be no less than $100,000 in the first year of commercial
marketing, $200,000 in the second year, $250,000 in the third year, $300,000 in
the fourth year, and $350,000 in the fifth and all following years.

4.  EQUITY TRANSACTIONS

COMMON AND PREFERRED STOCK

Common stock issued for services in the years 1990 through 1996 were recorded
based on the value of the services provided.

In April 1995, in accordance with the terms of his resignation and related

4.  EQUITY TRANSACTIONS (CONTINUED)

On March 24, 1996, the Company repurchased 155,803 shares of common stock
previously issued to an officer at $.002 per share. The repurchased shares were
canceled.

In May 1996, the Company's authorized capital was increased to 50,000,000 shares
of common stock, par value $.002, and 5,000,000 shares (of which 2,500,000
shares were designated as Series A preferred stock and 300,000 shares were
designated as Series B preferred stock) of preferred stock, par value $.01.

Pursuant to a private placement in May and June 1996, the Company issued
258,198 shares of Series B convertible preferred stock. The preferred
stockholders also received 258,198 shares of common stock. The total
consideration was $25,819,800. The per share price allocated to common stock and
Series B convertible preferred stock was $1 and $99, respectively. In connection
with the private placement, the Company paid $3,357,000 in commissions and
nonaccountable expenses to the placement agent, a related party, and issued
1,000 shares of common stock and 1,000 shares of Series B convertible preferred
stock as consideration for legal services valued at $100,000. In addition, the
placement agent received warrants to purchase 25,819.8 shares of Series B
convertible preferred stock at an exercise price of $110 per share. Such
warrants are exercisable until June 11, 2006. Other share issuance expenses
amounted to $142,000.

Each share of Series B preferred stock is convertible at any time, in whole or
in part, at the discretion of the holders, into common stock at $2 per share
(the Initial Conversion Price), which amounts to 12,959,900 shares at December
31, 1996. Twelve months after the final closing date (the Reset Date), the
Company may, at its option, cause conversion of the preferred stock, in whole or
in part, into common stock at the Initial Conversion Price if the closing price
of the common stock has exceeded 150% of the Initial Conversion Price for at
least 20 trading days in any 30 consecutive trading day period.

The Series B preferred stockholders are entitled to voting rights equivalent to
the number of common shares into which their preferred shares are convertible.
The Series B preferred stockholders are also entitled to receive, in preference
to the holders of common stock, an amount per preferred share of $135 plus any
declared but unpaid dividends.

4.  EQUITY TRANSACTIONS (CONTINUED)

At the second closing of the private placement on June 11, 1996, the 1,287,500
shares of Series A preferred stock were automatically converted to 643,750
shares of common stock. Notwithstanding such conversion, holders of the Series A
preferred stock will receive pro rata, 95.85% of shares of common stock of IPI
associated with the sale of the Product, as discussed in NOTE 2.

CONVERSION RESET

In accordance with the terms of the placement, the Initial Conversion Price will
be adjusted and reset effective as of the Reset Date if the average closing bid
price for the 30 consecutive trading days immediately preceding the Reset Date
(the 12-Month Trading Price) is less than 135% of the Initial Conversion Price,
or $2.70. If such is the case, the Initial Conversion Price will be reduced to
be equal to the greater of the 12-Month Trading Price divided by 1.35 or 50% of
the Initial Conversion Price (see NOTE 9).

STAGGERED LOCK-UP

Pursuant to the terms of the placement, 25% of each holder's shares of common
stock issuable upon conversion of the Series B preferred shares (the Conversion
Shares) are not subject to any restriction on resale (Lock-up). The remaining
75% of each holder's Conversion Shares are subject to a staggered Lock-up,
whereby 25% of the Conversion Shares are released from the Lock-up every three
months after the final closing, through and including March 11, 1997 (see NOTE
9).

STOCK OPTIONS

In April 1992, the Board of Directors approved the 1992 Stock Option Plan (the
Plan), which, as amended, authorizes up to 875,000 shares of common stock for
granting both incentive and nonqualified stock options to employees, directors,
consultants, and members of the scientific advisory board of the Company. The
exercise price and vesting period of the options are determined by the Board of
Directors at the date of grant. Options may be granted up to 10 years after the
Plan's adoption date and generally expire 10 years from the date of grant.

All outstanding options were issued at an exercise price of $.60 per share. At
December 31, 1996, options to purchase 47,778 shares of common stock were
exercisable, and options to purchase 815,000 shares of common stock were
available for grant under the Plan.

Certain officers and employees were also granted stock options in 1996, as
authorized by the Board of Directors, apart from the Plan. In May 1996, the
Comany's President and Chief Executive Officer (the President) received options
to purchase 637,745 shares of common stock at $.50 per share. Such options vest
at a rate of 1/16 per quarter over four years and are exercisable for a period
of seven years. Because the fair value of the Company's common stock at the date
of grant was determined to be $1 per share, the Company recorded $318,873 as
deferred compensation. Such deferred compensation is being amortized over four
years.

In September 1996, certain officers and an employee also received options to
purchase 505,000 shares of common stock at $.50 per share. Such options vest at
a rate of 1/16 per quarter over four years and are exercisable for a period of
seven years. Because the fair value of the Company's common stock at the date of
grant was determined to be $2 per share, the Company recorded $757,500 as
deferred compensation. Such deferred compensation is being amortized over four
years.

WARRANTS

The Company has issued warrants to purchase 177,538 (adjusted to comply with
anti-dilution provisions of the warrants) (June, July and September 1992),

9.  SUBSEQUENT EVENT

In January 1997, the Company initiated a revision to the staggered Lock-up and
Conversion Reset provisions of the private placement discussed in NOTE 4.
According to the terms of a letter to the shareholders of the Company, the
Company has requested that holders of the Series B preferred stock agree to a
modification of the original subscription agreement, such that the staggered
Lock-up would expire beginning three months after both listing and effectiveness
under the Securities Act of 1933 of the Company's Registration Statement for its
common stock (Effectiveness). As so modified, upon listing and Effectiveness,
25% of the Conversion Shares will not be subject to any Lock-up provisions. The
remaining 75% of the Conversion Shares will be subject to a staggered Lock-up,
such that every three months after both listing and Effectiveness, 25% of the
Conversion Shares will be released from Lock-up until the ninth month, at which
point, all Conversion Shares will no longer be subject to any Lock-up.

In addition, for those shareholders accepting the Lock-up modifications, the
Company will agree to provide additional reset protection, extending the Reset
Date to 12 months following the later of Effectiveness and listing. The terms of
this modified reset will be the same as the original reset provision, except
that the Company will not adjust the conversion price, but will issue additional
shares of common stock to effect the principles of the reset provision.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 24.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 145 of the Delaware General Corporation Law ("Section 145") authorizes a
court to award or a corporation's Board of Directors to grant indemnification to
directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act of 1933,
as amended (the "Securities Act"). Article Seven of the Company's Certificate of
Incorporation provides that the Corporation shall indemnify and advance expenses
to its directors ands officers to the fullest extent permitted by Section 145 of
the Delaware General Corporation Law. Article Nine of the Company's Certificate
of Incorporation provides that the liability of its directors is eliminated to
the fullest extent permitted by Section 102(b)(7) of the Delaware General
Corporation Law. Article V, Section 1 of the Company's By-Laws provides for
mandatory indemnification of its directors to the fullest extent authorized by
the Delaware General Corporation Law. Article V, Section 2 of the Company's
By-Laws provides for prepayment of expenses incurred by its directors to the
fullest extent permitted by, and only in compliance with, the Delaware General
Corporate Law. Article V, Section 6 of the Company's By-Laws provides for
permissive indemnification of its officers, employees and agents if and to the
extent authorized by the Board of Directors in compliance with the Delaware
General Corporation Law. These provisions in the Certificate of Incorporation
and the By-Laws do not eliminate the directors' fiduciary duty, and in
appropriate circumstances equitable remedies such as injunctive or other forms
of non-monetary relief will remain available under Delaware law. In addition,
each director will continue to be subject to liability for breach of the
director's duty of loyalty to the Company for acts or omissions not in good
faith or involving intentional misconduct, for knowing violations of law, for
actions leading to improper personal benefit to the director, and for payment of
dividends or approval of stock repurchases or redemptions that are unlawful
under Delaware law. The provisions also do not affect a director's
responsibilities under any other law, such as the federal securities laws or
state or federal environmental laws. Certain contractual indemnification
provisions contained in the Subscription Agreements of the Series B Offering
(Exhibit 4.6), the Series B Placement Warrants (Exhibit 4.12), the Bridge
Placement Warrants (Exhibit 4.7), the Meyerson Warrants (Exhibit 4.13), the
Shear/Kershman and Castelli Warrants (Exhibit 4.15), the Rutgers Warrants
(Exhibit 10.13) and the warrants to be issued to Drs. Wertheimer and Mermelstein
(Exhibit 4.16) indemnifying against certain liabilities the Company, its
officers, directors, affiliates and/or controlling person, including, in certain
cases, Paramount Capital, Inc., a company wholly owned by a substantial
shareholder of the Company, Lindsay A. Rosenwald, M.D. In addition, the Company
has obtained liability insurance for its directors and officers.

Item 26.  Recent Sales of Unregistered Securities

     In the last three years, the Company has issued and sold the following
securities (as adjusted to reflect a two-for one reverse stock split effected on
March 26, 1996):

     1.  On May 11, 1996 and June 11, 1996 (the "Closing Dates"), the Company
         consummated a private placement of an aggregate amount of approximately
         $25,800,000 of shares ("Units") of Series B Preferred Stock and Common
         Stock (the "Series B Offering"). The issuance of the above referenced
         securities was deemed to be exempt from registration under the
         Securities Act in reliance on Section 4(2) thereof and Rule 506 of
         Regulation D promulgated thereunder.

   
         The offer and sale of Units were conducted through the Company's
         Placement Agent (as defined below). In offering the Units, the
         Placement Agent confined its actions to activities sanctioned by
         Regulation D and did not engage in any form of general advertising or
         general solicitation in offering the Units. All investors of the Units
         represented to the Company that they were accredited investors and the
         Company had no reason to believe that such investors were not
         accredited investors. The Closing Dates were the only dates that the
         Company sold Units, and the Company timely filed a Form D (or amended
         Form D, as the case may be) on each of the Closing Dates. Each of the
         purchasers of the Units represented their intentions to acquire the
         securities for investment only and not with a view to, or for sale in
         connection with, any distribution thereof and appropriate legends were
         affixed to the share certificates issued in such transactions. The
         purchasers in such offering of Units were all the Selling
         Securityholders listed as such in the Registration Statement except for
         James D. Wolfensohn, Seymour Buehler and William J. Vanden Heuvel who
         are included in the list of selling Shareholders because of their
         ownership of shares of Common Stock issued upon exercise of Bridge
         Placements Warrants being registered hereby, and, employees of
         Paramount that are not included in the Registration Statement
         notwithstanding their purchase of units in the Series B Offering.
    

     2.  In connection with services rendered by Paramount Capital, Inc., as
         placement agent in the offering (the "Placement Agent"), the Company
         issued to the Placement Agent or its designees warrants to purchase an
         aggregate of approximately 25,820 shares of Series B Preferred Stock.
         The issuance of the above referenced securities was deemed to be exempt
         from registration under the Securities Act in reliance on Section 4(2)
         thereof and Rule 506 of Regulation D promulgated thereunder. Each of
         such recipients had the sophistication, knowledge and experience in
         financial matters as to be capable of evaluating the merits and risks
         of its investment in the Company, and had

                                      II-2

<PAGE>




         access to information, and the opportunity prior to its investment to
         ask questions of and receive answers from representatives of the
         Company, in each case concerning the finances, operations and business
         of the Company. In addition, the recipients of securities in each such
         transaction represented their intentions to acquire the securities for
         investment only and not with a view to or for sale in connection with
         any distribution thereof and appropriate legends were affixed to the
         certificates issued in such transactions.

     3.  On November 20, 1995, the Company entered into a License Agreement (the
         "TJU License Agreement') with Thomas Jefferson University ("TJU")
         pursuant to which TJU licensed to the Company certain patent and patent
         applications relating to a process for the modification of a patient's
         own tumor cells into a cancer vaccine (the "TJU License"). Pursuant to
         the TJU License Agreement, the Company issued 458,243 shares of Common
         Stock at a price of $.002 per share to each of TJU and Dr. David Berd,
         TJU's chief oncologist and the inventor of its cancer vaccine. In the
         stock subscription agreements ("Subscription Agreements") entered into
         by the Company, TJU and Dr. Berd on November 20, 1995, relating to the
         issuance of Common Stock to each of TJU and Dr. Berd, each of TJU and
         Dr. Berd represented, among other things, to the Company the following:
         that (i) it acquired the Common Stock for investment purposes only and
         not for resale for an indefinite period of time for its own account;
         (ii) it had such sophistication, knowledge and experience in financial
         and business matters as to be capable of evaluating the merits and
         risks of its investment in the Company; (iii) it had the ability to
         bear the economic risks of its investment for an indefinite period of
         time and could afford a complete loss of its investment; and (iv) it
         had access to information, and the opportunity prior to its purchase of
         the Common Stock to ask questions of and receive answers from
         representatives of the Company, in each case concerning the finances,
         operations and business of the Company. Also, as stated in the
         Subscription Agreements, the share certificates issued in connection
         with the above issuance of Common Stock had endorsed thereon legends
         regarding restrictions on the transfer of the Common Stock. Because of,
         among other things, the foregoing, the issuances of the above
         referenced securities was deemed to be exempt from registration under
         the Securities Act in reliance on Section 4(2) thereof.

     4.  The Castle Group, LLC ("The Castle Group") which may be deemed an
         affiliate of both the Company and the Placement Agent, identified,
         negotiated and acquired for the Company the TJU License. In connection
         therewith, The Castle Group and/or its designees were granted 1,832,971
         of Common Stock of the Company at a price of $.002 per share pursuant
         to an Engagement & Technology Acquisition Agreement dated October 20,
         1995 between The Castle Group and the Company. In the stock
         subscription agreements ("Castle Subscription Agreements") entered into
         by the Company, The Castle Group and its designees in September, 1995,
         relating to the Common Shares issued to each of The Castle Group and
         its designees, each of them represented, among other things, to the
         Company the following: that (i) it acquired the Common Stock for
         investment purposes only and not for resale for an indefinite period of
         time for its own account; (ii) that each of The Castle Group and its
         designees had such sophistication, knowledge and experience in
         financial and business matters as to be capable of evaluating the
         merits and risks of its investment in the Company; (iii) it had the
         ability to bear the economic risks of its investment for an indefinite
         period of time and could afford a complete loss of its investment; and
         (iv) it had access to information, and the opportunity prior to its
         purchase of the Common Stock to ask questions of and receive answers
         from representatives of the Company, in each case concerning the
         finances, operations and business of the Company. Also, as stated in
         the Subscription Agreements, the share certificates issued in
         connection with the above issuance of Common Stock had endorsed thereon
         legends regarding restrictions on the transfer of the Common Stock.
         Because of the foregoing, the issuances of the above referenced
         securities was deemed to be exempt from registration under the
         Securities Act in reliance on Section 4(2) thereof because such
         issuances were transactions not involving a public offering. In
         addition, each of the recipients of securities in such transaction
         represented their intention to acquire the securities for investment
         only and not with a view to or for sale in connection with any
         distribution thereof and conform to appropriate legends were affixed to
         the share certificates issued in such transactions. All recipients had
         adequate access, through their relationships with the Company, to
         information about the Company.

     5.  In 1995 and 1996, the Company pursuant to certain bridge financing
         transactions issued to only nine persons or entities ("Warrant
         Holders") (i) bridge notes aggregating $1,000,000 and (ii) warrants to
         purchase an aggregate of 312,500 shares of Common Stock at an exercise
         price of $.002 per share. In June 1996, such bridge notes were

                                      II-3

<PAGE>




         paid by the Company and all the warrants were exercised by the holders
         thereof. In connection with services rendered as the placement agent of
         the bridge financing, Paramount Capital, Inc. was issued warrants to
         purchase 62,500 shares of Common Stock at an exercise price of $.002
         per share. In connection with the issuances of the Warrants and the
         Placement Warrants, it represented, among other things, the following:
         that (i) it acquired the Common Stock for investment only and not for
         resale for an indefinite period for its own account; (ii) it had such
         sophistication, knowledge and experience in financial and business
         matters as to be capable of evaluating the merits and risks of its
         investment in the Company; (iii) it had the ability to bear the
         economic risks of its investment for an indefinite period of time and
         could afford a complete loss of its investment; and (iv) it had access
         to information, and the opportunity prior to its purchase of the Common
         Stock to ask questions of and receive answers from representatives of
         the Company, in each case concerning the finances, operations and
         business of the Company. Also, as stated in the Subscription
         Agreements, the share certificates issued in connection with the above
         issuance of Common Stock had endorsed thereon legends regarding
         restrictions on the transfer of the Common Stock. The issuances of the
         above referenced securities was deemed to be exempt from registration
         under the Securities Act in reliance on Section 4(2) thereof because
         such issuances were transactions not involving a public offering.

     6.  On October 24, 1996, the Company entered into an agreement with M. H.
         Meyerson & Co., Inc. ("Meyerson"), pursuant to which Meyerson may
         perform certain investment banking and financial advisory services on a
         non- exclusive basis for the Company (the "Investment Banking
         Agreement"). Pursuant to the Investment Banking Agreement, the Company
         granted to Meyerson warrants to purchase an aggregate of 100,000 shares
         of Common Stock of the Company at an exercise price of $3.00 per share.
         The issuance of the Meyerson Warrants were deemed to be exempt from
         registration under the Securities Act in reliance on Section 4(2)
         thereof because such issuances were transactions not involving a public
         offering. In addition, Meyerson represented its intention to acquire
         the securities for investment only and not with a view to or for sale
         in connection with any distribution thereof and appropriate legends are
         required to be affixed to the warrant certificates issuable in such
         transactions. Meyerson had adequate access, through its negotiations
         with the Company of the terms of the Investment Banking Agreement, to
         information about the Company.

     7.  On December 10, 1996, the Company entered into a license agreement with
         Rutgers, the State University of New Jersey and the University of
         Medicine and Dentistry of New Jersey (collectively, "Rutgers") pursuant
         to which Rutgers licensed to the Company certain patent applications
         relating to a series of compounds for the potential treatment of cancer
         and infectious diseases (the "Rutgers License"). Pursuant to the
         Rutgers License, the Company issued warrants to purchase 250,000 shares
         of Common Stock at a price of $4.12 per share to Rutgers (the "Rutgers
         Warrants"). The issuance of the Rutgers Warrants were deemed to be
         exempt from registration under the Securities Act in reliance on
         Section 4(2) thereof because such issuances were transactions not
         involving a public offering. In addition, Rutgers represented its
         intention to acquire the securities for investment only and not with a
         view to or for sale in connection with any distribution thereof and
         appropriate legends are required to be affixed to the warrant
         certificates issued in such transactions. Rutgers had adequate access,
         through its negotiations with the Company of the terms of the Rutgers
         License, to information about the Company.

     8.  In consideration of services rendered on behalf of the Company in
         connection with the acquisition and negotiation of the Rutgers License,

         Ph.D., $40,000 and to issue to Dr. Wertheimer warrants to purchase
         25,500 shares of Common Stock at an exercise price of $3.00 per share,
         exercisable for seven years (the "Wertheimer Warrants"). The issuance
         of the Wertheimer Warrants were deemed to be exempt from registration
         under the Securities Act in reliance on Section 4(2) thereof because
         such issuances were transactions not involving a public offering. In
         addition, Dr. Wertheimer represented his intention to acquire the
         securities for investment only and not with a view to or for sale in
         connection with any distribution thereof and appropriate legends are
         required to be affixed to the warrant certificates issued in such
         transactions. Dr. Wertheimer had adequate access, through his
         negotiations with the Company of the terms of the Rutgers License, to
         information about the Company.

     9.  In consideration of services rendered on behalf of the Company in
         connection with the acquisition and negotiation of the Texas A&M
         License, in February 1997, the Company agreed to pay Fred Mermelstein,
         Ph.D., $40,000 and

         Common Stock at an exercise price of $3.25 per share, exercisable for
         seven years (the "Mermelstein"). The issuance of such warrants were
         deemed to be exempt from registration under the Securities Act in
         reliance on Section 4(2) thereof because such issuances were
         transactions not involving a public offering. In addition, Dr.
         Mermelstein represented his intention to acquire the securities for
         investment only and not with a view to or for sale in connection with
         any distribution thereof and appropriate legends are required to be

ITEM 28.  UNDERTAKINGS

     The Company hereby undertakes that it will:

     (1) File, during any period in which it offers or sells securities, a
post-effective amendment to this registration statement to:

     (i) Include any prospectus required by section 10(a)(3) of the Securities
Act;

     (ii) Reflect in the prospectus any facts or events which, individually or
together, represent a fundamental change in the information in the registration
statement; and notwithstanding the foregoing, any increase or decrease in volume
of securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in the volume and price represent no more than a 20% change in the
maximum aggregate offering price set forth in the "Calculation of Registration
Fee" table in the effective registration statement;

     (iii) Include any additional or changed material information on the plan of
distribution.

     (2) For determining liability under the Securities Act, treat each
post-effective amendment as a new registration statement of the securities
offered, and the offering of the securities at that time to be the initial BONA
FIDE offering.

     (3) File a post-effective amendment to remove from registration any of the
securities that remain unsold at the end of the offering.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the Company
pursuant to the Delaware General Corporation Law, the Certificate of
Incorporation or the By-Laws of the Company, or otherwise, the Company 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 Company of expenses
incurred or paid by a director, officer, or controlling person of the Company 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 Company 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 of 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.

     The Company hereby undertakes that it will:

     (1) For determining any liability under the Securities Act, treat 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 Company pursuant to Rule 424(b)(1), or (4) or 497(h)
under the Securities Act as part of this registration statement as of the time
it was declared effective.

     (2) For determining any liability under the Securities Act, treat each
post-effective amendment that contains a form of prospectus as a new
registration statement for the securities offered in the registration statement,
and that offering of such securities at that time as the initial BONA FIDE
offering of those securities.

                             AVAX TECHNOLOGIES, INC.

                   Warrants To Purchase Shares Of Common Stock

No. ___                                                      [         ] Shares

                  This Warrant Certificate certifies that [ ], or registered
assigns (the "Holder"), is the owner of [ ] warrants (the "Warrants") (subject
to adjustment as provided herein), each of which represents the right to
subscribe for and purchase, at any time on or prior to [ ] (the "Expiration
Date"), from AVAX Technologies, Inc., a Delaware corporation (the "Company"),
one share of Common Stock, par value $.002 per share, of the Company (the
"Common Shares") at a per share exercise price (the "Exercise Price") of $[ ]
(subject to adjustment as provided herein).

                  The Warrants represented by this Warrant Certificate are
subject to the following provisions, terms and conditions:

                  SECTION 1. Exercise. (a) The Warrants may be exercised, in
whole or in part, on or prior to the Expiration Date, by the Holder:

                  (i) by surrender of this Warrant Certificate (with the
                  subscription form attached hereto duly executed) at the
                  principal office of the Company at 4520 Main Street, Suite
                  930, Kansas City, Missouri (or such other office or agency of
                  the Company as may be designated by notice in writing to the
                  Holder at the address of such Holder appearing on the books of
                  the Company), accompanied by proper payment of the aggregate
                  Exercise Price, or the proportionate part thereof if the
                  Warrants are exercised in part, in cash or by official bank or
                  certified check made payable to the Company. Upon such
                  payment, the Common Shares so purchased shall be deemed
                  (retroactively) to have been issued to the Holder as the
                  record owner of such Common Shares as of the close of business
                  on the Exercise Date. Certificates representing the Common
                  Shares so purchased, together with any cash for fractional


<PAGE>

                  Common Shares paid pursuant to Section 5, shall be delivered
                  to the Holder promptly and in no event later than 10 days
                  after payment of the Exercise Price; or

                  (ii) by the surrender of this Warrant Certificate (with the
                  cashless exercise form attached hereto duly executed) (a
                  "Cashless Exercise") at the principal office of the Company at
                  4520 Main Street, Suite 930, Kansas City, Missouri (or such
                  other office or agency of the Company as may be designated by
                  notice in writing to the Holder at the address of such Holder
                  appearing on the books of the Company). Such presentation and
                  surrender shall be deemed a waiver of the Holder's obligation
                  to pay the aggregate Exercise Price, or the proportionate part
                  thereof if this Warrant is exercised in part. In the event of
                  a Cashless Exercise, the Holder shall exchange its Warrant
                  Certificate for that number of shares of Common Stock
                  determined by multiplying the number of shares of Common Stock
                  subject to such Cashless Exercise by a fraction, the numerator
                  of which shall be the difference between the then current
                  market price per share of the Common Stock and the per share
                  Exercise Price, and the denominator of which shall be the then
                  current market price per share of the Common Stock. For
                  purposes of any computation under this Section, the then
                  current market price per share of Common Stock at any date
                  (the "Market Price") shall be deemed to be last sale price of
                  the Common Stock on the business day prior to the date of the
                  Cashless Exercise or, in case no such reported sales take
                  place on such day, the average of the last reported bid and
                  asked prices of the Common Stock on such day, in either case
                  on the principle national securities exchange on which the
                  Common Stock is admitted to trading or listed, or if no listed
                  or admitted to trading on any such exchange, the
                  representative closing bid price of the Common Stock as
                  reported by the National Association of Securities Dealers,
                  Inc. Automated Quotations System ("NASDAQ"), or other similar
                  organization if NASDAQ is no longer reporting such
                  information, or if not so available, the fair market price of
                  the Common Stock as determined by the Board of Directors.

                  (b) In the event of any partial exercise of this Warrant
Certificate, the Company shall deliver to the Holder, together with the Common
Shares issuable upon such partial exercise, a new Warrant Certificate of like
tenor evidencing the Warrants remaining unexercised.

                  SECTION 2. Reservation of Shares; Payment of Taxes. (a) The
Company covenants that it will at all times reserve and keep available out of
its authorized Common Stock, solely for the purpose of issue upon exercise of
Warrants, such number of Common Shares as shall then be issuable upon the
exercise of all outstanding Warrants. The Company covenants that all Common
Shares which shall be issuable upon exercise of the Warrants shall, at the time
of delivery (assuming full payment of the Exercise Price thereof), be duly and
validly issued, fully paid, nonassessable and free from all issuance taxes,
liens and charges with respect to the issue thereof (other than those which the
Company shall promptly pay or discharge).

                  (b) The Company shall pay all documentary, stamp or similar
taxes and other similar governmental charges that may be imposed with respect to
the issuance or delivery of any Common Shares upon exercise of the Warrants;
provided, however, that if the Common Shares are 


<PAGE>

to be delivered in a name other than the name of the Holder, no such delivery
shall be made unless the person requesting the same has paid to the Company the
amount of transfer taxes or charges incident thereto, if any.

                  SECTION 3. Loss or Mutilation. Upon receipt by the Company of
evidence satisfactory to it of the ownership of and loss, theft, destruction or
mutilation of this Warrant Certificate and (in case of loss, theft or
destruction) of indemnity satisfactory to it, and (in the case of mutilation)
upon surrender and cancellation thereof, the Company shall execute and deliver
to the Holder in lieu thereof a new Warrant Certificate of like tenor
representing an equal aggregate number of Warrants. Applicants for a substitute
Warrant Certificate shall comply with such other reasonable regulations and pay
such other reasonable charges as the Company may prescribe.

                  SECTION 4. Anti-Dilution Provisions. (a) In the case the
Company shall hereafter (i) pay a dividend or make a distribution on its capital
stock in shares of Common Stock, (ii) subdivide its outstanding shares of Common
Stock into a greater number of shares, (iii) combine its outstanding shares of
Common Stock into a smaller number of shares or (iv) issue by reclassification
of its Common Stock any shares of capital stock of the Company, the Exercise
Price shall be adjusted so that the Holder upon the exercise hereof shall be
entitled to receive the number of shares of Common Stock or other capital stock
of the Company which he would have owned immediately following such action had
such Warrant been exercised immediately prior thereto. An adjustment made
pursuant to this Subsection 4(a) shall become effective immediately after the
record date in the case of a dividend or distribution and shall become effective
immediately after the effective date in the case of a subdivision, combination
or reclassification.

                  (b) In the case of any capital reorganization or
reclassification, or any consolidation or merger to which the Company is a party
other than a merger or consolidation in which the Company is the continuing
corporation, or in the case of any sale or conveyance to another entity of the
property of the Company as an entirety or substantially as an entirety, or in
the case of any statutory exchange of securities with another corporation
(including any exchange effected in connection with a merger of a third
corporation into the Company), the Holder of this Warrant shall have the right
thereafter to receive on the exercise of this Warrant the kind and amount of
securities, cash or other property which the Holder would have owned or have
been entitled to receive immediately after such reorganization,
reclassification, consolidation, merger, statutory exchange, sale or conveyance
had this Warrant been exercised immediately prior to the effective date of such
reorganization, reclassification consolidation, merger, statutory exchange, sale
or conveyance and in any such case, if necessary, appropriate adjustment shall
be made in the application of the provisions set forth in this Section 4 with
respect to the rights and interests thereafter of the Holder of this Warrant to
the end that the provisions set forth in this Section 4 shall thereafter
correspondingly be made applicable, as nearly as may reasonably be, in relation
to any shares of stock or other securities or property thereafter deliverable on
the exercise of this Warrant. The above provisions of this Subsection 4(b) shall
similarly apply to successive reorganizations, reclassifications,
consolidations, mergers, statutory exchanges, sales or conveyances. The issuer
of any shares of stock or other securities or property thereafter deliverable on
the exercise of this Warrant shall be responsible for all of the agreements and
obligations of the Company hereunder. Notice of any such reorganization,
reclassification, consolidation, merger, statutory exchange, sale 


<PAGE>

or conveyance and of said provisions so proposed to be made, shall be mailed to
the Holders of the Warrants not less than 30 days prior to such event. A sale of
all or substantially all of the assets of the Company for a consideration
consisting primarily of securities shall be deemed a consolidation or merger for
the foregoing purposes.

                  (c) Whenever the Exercise Price is adjusted as provided in
this Section 4 and upon any modification of the rights of a Holder of Warrants
in accordance with this Section 4, the Company shall promptly mail to the
Holders of the warrants a certificate of the Company's chief financial officer
setting forth the Exercise Price and the number of Common Shares after such
adjustment or the effect of such modification, a brief statement of the facts
requiring such adjustment or modification and the manner of computing the same,
and, at the request of the Holder of any Warrant, obtain, at the Company's
expense, a certificate of a firm of independent public accountants of recognized
standing selected by the Board of Directors (who may be the regular auditors of
the Company) to such effect and cause of such certificate to be mailed to the
Holders of the Warrants.

                  (d) In case any event shall occur as to which the other
provisions of this Section 4 are not strictly applicable but as to which the
failure to make any adjustment would not fairly protect the purchase rights
represented by this Warrant in accordance with the essential intent and
principles hereof then, in each such case, the Holders of Warrants representing
the right to purchase a majority of the Common Shares subject to all outstanding
Warrants may appoint a firm of independent public accountants of recognized
national standing reasonably acceptable to the Company, which shall give their
opinion as to the adjustment, if any, on a basis consistent with the essential
intent and principles established herein, necessary to preserve the purchase
rights represented by the Warrants. Upon receipt of such opinion, the Company
will promptly mail a copy thereof to the Holder of this Warrant and shall make
the adjustments described therein. The fees and expenses of such independent
public accountants shall be borne by such Holders.

                  (e) No adjustments in the Exercise Price shall be required
unless such adjustment would require an increase or decrease of at least $0.05
per share of Common Stock. All calculations under this Section 4 shall be made
to the nearest cent or to the nearest 1/100th of a share, as the case may be.
Anything in this Section 4 to the contrary notwithstanding, the Company shall be
entitled to make such reductions in the Exercise Price, in addition to those
required by this Section 4 as it in its discretion shall deem to be advisable in
order that any stock dividend, subdivision of shares or distribution of rights
to purchase stock or securities convertible or exchangeable for stock hereafter
made by the Company to its stockholders shall not be taxable.

                  (f) Whenever the Exercise Price is adjusted as provided in
this Section 4 and upon any modification of the rights of a Holder of Warrants
in accordance with this Section 4, the Company shall promptly mail to the
Holders of the warrants a certificate of the Company's chief financial officer
setting forth the Exercise Price and the number of Common Shares after such
adjustment or the effect of such modification, a brief statement of the facts
requiring such adjustment or modification and the manner of computing the same,
and, at the request of the Holder of any Warrant, obtain, at the Company's
expense, a certificate of a firm of independent public accountants of recognized
standing selected by the Board of Directors (who may be the regular auditors of
the Company) to such effect and cause of such certificate to be mailed to the
Holders of the Warrants.


<PAGE>

                  SECTION 5. Fractional Shares. The Company may, but shall not
be required to, issue fractional Common Shares on exercise of the Warrants. The
number of full Common Shares which shall be issuable upon such exercise of
Warrants by the Holder shall be computed on the basis of the aggregate number of
whole Common Shares purchasable on exercise of all Warrants held by the Holder.
If any fraction of a Common Share would, except for the provisions of this
Section 6, be issuable on the exercise of Warrants, the Company may if it elects
pay an amount in cash calculated by it to be equal to the then fair value of one
Common Share, as determined by the Board of Directors of the Company in good
faith, multiplied by such fraction computed to the nearest whole cent.

                  SECTION 6. Warrant Holders Not Deemed Stockholders. The Holder
shall not, as the holder of Warrants, be entitled to receive dividends or be
deemed the holder of Common Shares that may at any time be issuable upon the
exercise of such Warrants for any purpose whatsoever.

                  SECTION 7. Governing Law. This Warrant Certificate shall be
governed by and construed in accordance with the laws of the State of Delaware,
without reference to principles of conflict of laws.

                  SECTION 8. Assignment. This Warrant Certificate may not be
assigned in whole or in part or transferred by the Holder without the prior
written consent of the Company and any such purported transfer without such
prior written consent shall be null and void ab initio.

                  IN WITNESS WHEREOF, the Company has caused this Warrant
Certificate to be duly executed as of the date first above written.

                                        Registration on Form SB-2

Dear Sirs:

                  We have acted as counsel for AVAX Technologies, Inc., a
Delaware corporation (the "Issuer"), in connection with the preparation of the
registration statement on Form SB-2 (the "Registration Statement") filed with
the Securities and Exchange Commission (the "Commission") on August 1, 1996,
Registration Number 33-09349, as amended by Amendment No. 1 thereto filed with
the Commission on September 23, 1996, as further amended by Amendment No. 2
thereto filed with the Commission on November 6, 1996, and as further amended by
Amendment No. 3 thereto filed with the Commission on November 8, 1996, as
further amended by Amendment No. 4 thereto filed with the Commission on February
26, 1997, and as further amended by Amendment No. 5 thereto filed with the
Commission on April 4, 1997, under the Securities Act of 1933 (the "Act") for
the registration under the Act of the following securities of the Issuer:

                  (i) 570,398 shares of common stock, par value $.002 per share
                  ("Common Stock");

                  (ii) 12,894,900 shares of Common Stock issuable upon
                  conversion of currently outstanding shares of Series B
                  Convertible Preferred Stock, par value of $.01 per share (the
                  "Series B Preferred Stock"); and
 
                  (iii) up to 95,300 shares of Common Stock issuable upon (a)
                  the conversion of shares of Series B Preferred Stock issuable
                  upon exercise of the warrants issued to the placement agent
                  and/or its designees relating to the offering of the Series B
                  Preferred Stock (the "Series B Placement Warrants") and (b)
                  exercise of warrants issued to the placement agent


                                          2
<PAGE>
 

                  and/or its designees for certain bridge financing transactions
                  of the Company (the "Bridge Placement Warrants," and together
                  with the Series B Placement Warrants, the "Placement
                  Warrants").

                  In that connection, we have examined originals or copies,
certified or otherwise identified to our satisfaction, of certificates of public
officials and corporate records, instruments and documents of or affecting the
Issuer, including, without limitation, (i) the Certificate of Incorporation of
the Issuer, as amended to date; (ii) the Bylaws of the Issuer, as amended to
date; (iii) resolutions adopted by the Board of Directors and Stockholders of
the Issuer; (iv) the Certificate of Designations for the Series B Preferred
Stock; (v) a form of specimen stock certificate for the Common Stock; (vi) a
form of specimen stock certificate for the Series B Preferred Stock; (vii) a
form of the Series B Placement Warrant; and (viii) a form of the Bridge
Placement Warrant. We have also examined originals or copies, certified or
otherwise identified to our satisfaction, of certificates of officers of the
Issuer, and have reviewed such questions of law and made such other inquiries,
as we have deemed necessary or appropriate for the purpose of rendering this
opinion.

                  In rendering our opinion, we have relied, as to matters of
fact, upon representations and warranties of the Issuer and upon such
certificates and other instruments of officers of the Issuer and public
officials as we have deemed necessary or appropriate for the purpose of
rendering this opinion, in each case without independent investigation or
verification. Additionally, without any independent investigation or
verification, we have assumed (i) the genuineness of all signatures, (ii) the
authenticity of all documents submitted to us as originals and the conformity
with the original documents of all documents submitted to us as certified,
conformed or photostatic copies, (iii) the authority of all persons signing any
document other than the officers of the Issuer, where applicable, signing in
their capacity as such, (iv) the enforceability of all the agreements we have
reviewed in accordance with their respective terms against the parties thereto,
and (v) the truth and accuracy of all matters of fact set forth in all
certificates and other instruments furnished to us.

                  Based upon the foregoing, and subject to the limitations,
qualifications and assumptions set forth herein, we are of the opinion that:

                  1. The Issuer is a corporation duly incorporated and is in
good standing under the laws of the State of Delaware.

                  2. The 570,398 shares of Common Stock which may be sold in
accordance with the provisions of the Registration Statement have been legally
issued and are fully paid and nonassessable.

                  3. The 12,894,900 shares of Common Stock issuable upon
conversion


<PAGE>

 
of currently outstanding shares of Series B Preferred Stock have been duly
authorized for issuance, and when issued upon conversion of the Series B
Preferred Stock will be legally issued, fully paid and nonassessable.

                  4. The aggregate of up to 72,800 shares of Common Stock
issuable upon conversion of the Series B Preferred Stock after exercise of the
Series B Placement Warrants have been duly authorized for issuance, and when
issued upon conversion of the Series B Preferred Stock after exercise of the
Series B Placement Warrants, and the payment of the applicable exercise price
thereof or the use of the cashless exercise provision thereof will be legally
issued, fully paid and nonassessable.

                  5. The aggregate of up to 22,500 shares of Common Stock
issuable upon exercise of the Bridge Placement Warrants have been duly
authorized for issuance, and when issued upon exercise of the Bridge Placement
Warrants, and the payment of the applicable exercise price thereof or the use of
the cashless exercise provision thereof will be legally issued, fully paid and
non-assessable.

         (a) a semi-annual royalty based on Net Sales during the two most
         recently concluded fiscal quarters calculated as follows:

                  (i) to the extent a Rutgers/UMDNJ Patent Right underlying a
                  Licensed Product is unexpired in a country, a royalty of [***]



         [***]



         [***]


Subject to Article 17 this Agreement, amounts due under this Article 5.2 alone
shall not be reduced [***]

         5.2 No Payment Obligations shall be due with respect to any sale or
sublicense covering any Licensed Product in a country if:

         (a) there are no issued Rutgers/UMDNJ Patent Rights underlying such
         Licensed Product in such country; and

         (b) to the extent that a patent application is pending, there is no
         claim within such patent application on which a royalty herein can
         reasonably be based which has been pending for less than seven (7)
         years since the initial filing date; and

         (c) no Rutgers/UMDNJ Proprietary Technology is used with respect to, or
         embodied in such Licensed Product.

         5.3 Royalties payable to Rutgers/UMDNJ shall be paid semi-annually on

         5.4 Licensee shall pay to Rutgers/UMDNJ a minimum annual payment equal
to the amount set forth on the following schedule:


         [***]



for the term of this Agreement beginning with the year of First Commercial Sale
of any Licensed Product in a Major Market Country. This minimum annual payment
shall be paid to Rutgers/UMDNJ by December 31 of each year and shall be credited
against the Payment Obligations due and owing for the calendar year in which the
minimum annual payment is supposed to be made. The first year's minimum annual
payment shall be prorated by the fractional number of full months remaining in
that calendar.

         5.5 Licensee shall be entitled to credit against the royalty revenue
payable pursuant to paragraph 5.1(a) and (b) in the amount of [***] provided

be negotiated in good faith between the parties at that time.

         5.6 All amounts due Rutgers/UMDNJ shall be payable in United States
Dollars in New Brunswick, New Jersey. When Licensed Products are sold for monies
other than United States Dollars, the earned royalties will first be determined
in the foreign currency of the country in which such Licensed Products were sold
and then converted into equivalent United States Dollars. The exchange rate will
be the United States Dollar buying rate quoted in the Wall Street Journal on the
last day of the reporting period.

         5.7 Royalties earned with respect to sales occurring in any country
outside the United States shall be reduced by any taxes, fees or other charges
imposed by the government of such country on the remittance of income. The
parties shall reasonably cooperate with each other in execution of documents
which will avoid or reduce such taxes, fees and charges. Licensee shall be
responsible for all bank transfer charges.

         5.8 If at any time legal restrictions prevent the acquisition or prompt
remittance of United States Dollars by Licensee with respect to any country
where a Licensed Product is sold, Licensee shall pay royalties due to
Rutgers/UMDNJ from Licensee's other sources of United States Dollars.

         5.9 In the event that any patent or any claim thereof included within
the Rutgers/UMDNJ Patent Rights shall be held invalid in a final decision by a
court of competent jurisdiction and last resort and from which no appeal has or
can be taken, all obligation to pay royalties based on such patent or claim or
any claim patentably indistinct therefrom shall cease as of the date of such
final decision. Licensee shall not, however, be relieved from paying any
royalties that accrued before such decision or that are based on another patent
or claim not involved in such decision, or that are based on Rutgers/UMDNJ
Technology.

                                  6. DILIGENCE

         6.1 Licensee, upon execution of this Agreement, shall use all
reasonable efforts to develop, test, obtain regulatory approval, and manufacture
Licensed Products in all Major Market Countries, and any other countries in
which it is deemed reasonable and prudent to do so, in which Rutgers/UMDNJ
Patent Rights exist within a reasonable time after execution of this Agreement
and shall, within a reasonable time after obtaining requisite regulatory
approvals, earnestly and diligently endeavor to market and sell the same in
quantities sufficient to meet the market demands therefor.

         6.2 Licensee shall be entitled to exercise prudent and reasonable
business judgment in meeting its diligence obligations hereunder.

         6.3 If Licensee or its sublicensees fail to perform any of the
following:

         (a) commence commercial marketing of Licensed Products in each Major
         Market Country within six (6) months of receiving approval of such
         Licensed Product in such country unless there is a significant, prudent
         and reasonable business reason not to do so;

         (b) reasonably fill the market demand for Licensed Products in each
         Major Market Country following commencement of marketing in such
         country at all times during the exclusive period of this Agreement; or


                                       11

<PAGE>



         (c) until the Minimum Payment Obligation's of paragraph 5.4 are
         triggered, spend an aggregate of not less than:

                  (i) $200,000 in Year One; 
                  (ii) $300,000 in Year Two; and 
                  (iii) $500,000 in Year Three, and each year of this Agreement
                  thereafter

         for the development, research, manufacture, regulatory approval,
         marketing and selling of Licensed Products (including without
         limitation, allocated overhead expenses and Sponsored Research
         expenses);

         (d) execute the Sponsored Research Agreement within forty-five (45)
         days of the execution of this Agreement, or, where good faith
         negotiations are continuing, for such longer period of time as agreed
         to by and between the parties, providing for the funding of research in
         the amount of at least $100,000 for the first three years;

then Rutgers/UMDNJ shall have the right and option upon sixty (60) days written
notice, either to terminate this Agreement in the countries where Licensee has
failed to perform or to reduce Licensee's exclusive license to a nonexclusive
license in the countries where Licensee has failed to perform, provided that any
such notice must be given within four (4) months after the occurrence or from
the time at which Rutgers/UMDNJ Office of Technology Transfer has or should have
knowledge of the occurrence of the alleged violation complained of in such
notice and Licensee does not cure the matter specified in such notice within
said sixty (60) day period. Should the Licensee fail to cure the matters
specified in such notice within said sixty (60) day period, the termination
shall be effective at the end of said period. This right, if exercised by
Rutgers/UMDNJ, supersedes the rights granted in Article 2 (GRANT).


                         7. PROGRESS AND ROYALTY REPORTS

         7.1 Beginning December 31, 1997, and annually thereafter, Licensee
shall submit to Rutgers/UMDNJ a progress report covering Licensee's activities
related to the development and testing of all Licensed Products and the
obtaining of the governmental approvals necessary for marketing. These progress
reports shall be made for each Licensed Product in each Major Market Country and
for other countries upon request by Rutgers/UMDNJ.

         7.2 Subject to applicable law, the progress reports submitted under
paragraph 7.1 shall include sufficient information to enable Rutgers/UMDNJ to

<PAGE>



                  progress in obtaining government approvals

         -        market plans for introduction of Licensed Products in
                  countries in which Licensed Product has not been introduced 

         -        aggregate dollar value spent in the reporting period for
                  research, development, and marketing of Licensed Products

         -        activities in obtaining sublicensees and activities of
                  sublicensees

         -        financial statements as of the end of the previous calendar
                  quarter

         -        activities under the Research Agreement

         7.3 Licensee shall have a continuing responsibility to keep
Rutgers/UMDNJ informed of its large/small Entity status (as defined by the
United States Patent and Trademark Office).

         7.4 Subject to applicable law, Licensee shall report to Rutgers/UMDNJ
in its immediately subsequent progress or royalty report the date of First
Commercial Sale of each Licensed Product in each country.

         7.5 After the First Commercial Sale of a Licensed Product anywhere in
the world by Licensee or its sublicensees, Licensee will make semi-annual
royalty reports to Rutgers/UMDNJ on or before each June 30 and December 31 of
each year. Each such royalty report will cover Licensee's two most recently
completed calendar quarters and will show the following:

         (a) the gross sales and Net Sales of each type of Licensed Product and
         a clear indication of how Net Sales and other consideration due to
         Rutgers/UMDNJ hereunder were calculated;

         (b) the royalties and other consideration, in U.S. dollars, payable
         hereunder;

         (c) the exchange rate used, if any; and

         (d) any other information reasonably requested by Rutgers/UMDNJ in
         support or explanation thereof.

         7.6 If no sales of Licensed Products have been made during any
reporting period, a statement to this effect shall be made by Licensee.



                              8. BOOKS AND RECORDS

         8.1 Licensee shall keep, cause its Affiliates to keep and use its best
efforts to cause its sublicensees to keep complete and accurate books and
records in accordance with generally accepted accounting principles accurately
showing all transactions and information relating to this Agreement. Such books
and records shall be preserved for at least five (5) years from the date of the
entry to which they pertain and shall be open to inspection by representatives
or agents of Rutgers/UMDNJ reasonably acceptable to Licensee at reasonable times
upon reasonable notice and may be exercised

                                       13

<PAGE>



no more than two times per calendar year.

         8.2 The fees and expenses of Rutgers/UMDNJ representatives performing
such an examination shall be borne by Rutgers/UMDNJ. However, if an error in
royalties in an amount equal to the greater of five percent (5%) of the total
royalties due for any year or fifty thousand dollars ($50,000) is discovered,
then the fees and expenses of these representatives shall be borne by Licensee.


                            9. TERM OF THE AGREEMENT

         9.1 Unless otherwise terminated by operation of law or by acts of the
parties in accordance with the provisions of this Agreement, this Agreement
shall be in force from the effective date recited on page one and shall remain
in effect with respect to each Licensed Product in each country of the world
until the longer of:

         (a) expiration of the last-to-expire Rutgers/UMDNJ Patent Right
         licensed under this Agreement in such country; or

         (b) ten years from the date of First Commercial Sale of a Licensed
         Product in such country.

         9.2 Any expiration or termination of this Agreement shall not affect
the rights and obligations set forth in the following Articles:



          Article 8           Books and Records
          Article 12          Disposition of Licensed Products on Hand Upon

                        10. TERMINATION BY RUTGERS/UMDNJ

         10.1 If Licensee should materially breach or fail to perform in any
material respect any material provision of this Agreement then Rutgers/UMDNJ may
give written notice of such default to Licensee. If Licensee should fail to cure
such default within sixty (60) days after the effective date of such notice,
Rutgers/UMDNJ shall have the right to terminate this Agreement and the licenses
herein by a second written notice to Licensee. If a notice of termination is
sent to Licensee, this Agreement shall automatically terminate on the effective
date of such notice. Termination shall not relieve Licensee of its obligation to
pay all amounts due to Rutgers/UMDNJ as of the effective date

                                       14

<PAGE>



of termination and shall not impair any accrued right of Rutgers/UMDNJ.

         10.2 Rutgers/UMDNJ may terminate this Agreement immediately on written
notice to Licensee upon the occurrence of a Bankruptcy Event with respect to
Licensee.


                           11. TERMINATION BY LICENSEE

         11.1 Licensee shall have the right at any time to terminate this
Agreement in whole or as to any portion of Rutgers/UMDNJ Patent Rights by giving
ninety (90) days notice thereof in writing to Rutgers/UMDNJ. If such termination
in whole is within the first year of this Agreement, other than in the first
three (3) months, Licensee shall pay Rutgers/UMDNJ a relicensing fee of Ten
Thousand Dollars ($10,000).

         11.2 Any termination pursuant to the above paragraph shall not relieve
Licensee of any obligation or liability accrued hereunder prior to such
termination or rescind anything done by Licensee or any payments made to
Rutgers/UMDNJ hereunder prior to the time such termination becomes effective,
and such termination shall not affect in any manner any rights of Rutgers/UMDNJ
arising under this Agreement prior to such termination.


              12. DISPOSITION OF LICENSED PRODUCTS AND INFORMATION
                            ON HAND UPON TERMINATION

         12.1 Upon termination of this Agreement by either party:

         (a) Licensee may sell all previously made or partially made Licensed
         Products, but no more (and may complete Licensed Products for which
         materials have been ordered or manufactured) within a period of one
         hundred and twenty (120) days after the effective date of termination,
         provided, however, that the disposition of such Licensed Products shall
         be subject to the terms of this Agreement including, but not limited
         to, the payment of royalties at the rate and at the time provided
         herein and the rendering of reports thereon; and

         (b) Licensee shall promptly return, and shall use all reasonable
         efforts to cause its sublicensees to return, to Rutgers/UMDNJ all
         Rutgers/UMDNJ Technology, and other property belonging to
         Rutgers/UMDNJ, if any, that has been provided to Licensee or
         sublicensees hereunder, and all copies and facsimiles thereof and
         derivatives therefrom (except that Licensee may retain one copy of
         written material for record purposes only, provided such material is
         not used by Licensee for any other purpose and is not disclosed to
         others).

<PAGE>



           13. USE OF NAMES, TRADEMARKS, AND CONFIDENTIAL INFORMATION

         13.1 Nothing contained in this Agreement shall be construed as granting
any right to Licensee or its Affiliates to use in advertising, publicity, or
other promotional activities any name, trade name, trademark, or other
designation of Rutgers/UMDNJ or any of its units (including contraction,
abbreviation or simulation of any of the foregoing) without the prior, written
consent of Rutgers/UMDNJ; provided, however, that Rutgers/UMDNJ acknowledges and
agrees that Licensee may use Rutgers/UMDNJ's name and the names of Drs. LaVoie
and Liu in various documents used by Licensee for capital raising and financing
without such prior written consent where the use of such names may be required
by law. Rutgers/UMDNJ acknowledges that Drs. LaVoie and Liu may act as
consultants and scientific advisors to Licensee with respect to the licenses
granted to Licensee hereunder, subject to Rutgers/UMDNJ policies.

         13.2 Nothing herein shall be deemed to establish a relationship of
principal and agent between Rutgers/UMDNJ and Licensee, nor any of their agents
or employees for any purpose whatsoever. This Agreement shall not be construed
as constituting Rutgers/UMDNJ and Licensee as partners, or as creating any other
form of legal association or arrangement which would impose liability upon one
party for the act or failure to act of the other party.

         13.3 In the event that Rutgers/UMDNJ desires to publish or disclose, by
written, oral or other presentation, Licensed Improvements, Rutgers/UMDNJ Patent
Rights, Rutgers/UMDNJ Proprietary Technology or any material information related
thereto which the Inventors reasonably believe jeopardize the aforementioned
rights the Inventors shall notify Licensee and Rutgers/UMDNJ in writing by
facsimile where confirmed by the receiving party, and/or by certified or
registered mail (return receipt requested) of their intention at least fifteen
(15) days prior to any speech, lecture or other oral presentation and at least
60 days before any written or other publication or disclosure. The Inventors
shall include with such notice a description of any proposed oral presentation
or, in any proposed written or other disclosure, a current draft of such
proposed disclosure or abstract. Licensee may request that the Inventors and
Rutgers/UMDNJ, no later than 30 days following the receipt of such notice, delay
such publication or disclosure in order to enable Licensee to request that
Rutgers/UMDNJ file, or have filed on its behalf, a patent application, copyright
or other appropriate form of intellectual property protection related to the
information to be disclosed. Upon receipt of such request, Rutgers/UMDNJ and the
Inventors shall arrange for a delay in publication or disclosure until such time
as Rutgers/UMDNJ has filed, or had filed on its behalf, such patent application,
copyright or other appropriate form of intellectual property protection in form
and in substance reasonably satisfactory to Licensee and Rutgers/UMDNJ. If
neither the Inventors nor Rutgers/UMDNJ receive any such request from Licensee
to delay publication or disclosure, Rutgers/UMDNJ or the Inventors may submit
such material for publication or presentation or make such other publication or
disclosure. If Rutgers/UMDNJ has not filed, or had filed on its behalf, such
patent application, copyright or other appropriate intellectual property
protection within thirty (30) days of a request by Licensee to Rutgers/UMDNJ to
do so, Licensee shall have the right but not the obligation to file on behalf of
Rutgers/UMDNJ any appropriate intellectual property protection upon notice to
Rutgers/UMDNJ within fifteen (15) days of the expiration of said thirty (30) day
period. Upon receipt of such notice, Rutgers/UMDNJ shall arrange

                                       16

<PAGE>



for a delay in publication or disclosure until such time as Licensee has filed
such patent application, copyright or other appropriate form of intellectual
property protection which Licensee agrees to file as soon as is reasonably
practicable provided, however that said deferral shall not exceed ninety (90)
days from the receipt of such notice.

                             15. PATENT PROSECUTION
                                 AND MAINTENANCE

         15.1 Rutgers/UMDNJ, in cooperation with Licensee shall diligently
prosecute and maintain the United States patents comprising Rutgers/UMDNJ Patent
Rights through counsel mutually agreeable to Licensee and Rutgers/UMDNJ. Counsel
shall take instructions from Rutgers/UMDNJ. Additionally, Rutgers/UMDNJ or
patent counsel shall provide a copy of any and all correspondence or other
relevant documentation between Rutgers/UMDNJ and/or patent counsel and the
United States Patent and Trademark Office, any governmental agency or other
party (excluding internally distributed correspondence) where such documentation
pertains to the prosecution and maintenance of the aforementioned United States
patents which documentation shall include but not be limited to all bar dates,
filing dates, notification dates and other relevant dates. Licensee agrees to
keep confidential all documentation relating to the prosecution and maintenance
of Rutgers/UMDNJ Patent Rights so long as it is Rutgers/UMDNJ Confidential
Material.

         15.2 Rutgers/UMDNJ shall give due consideration to amending any patent
application to include claims reasonably requested by Licensee to protect the
Licensed Products contemplated to be sold under this Agreement.

         15.3 Rutgers/UMDNJ shall cooperate with Licensee in applying for an
extension of the term of any patent included within Rutgers/UMDNJ Patent Rights
if appropriate under any applicable statute. Licensee shall prepare all such
documents, and Rutgers/UMDNJ agrees to execute such documents and to take such
additional action as Licensee may reasonably request in connection therewith.

         15.4 All future costs of preparing, filing, prosecuting, defending and
maintaining all United States patent applications and/or patents, including
interferences and oppositions, and, subject to paragraphs 15.5 and 15.6, all
corresponding foreign patent applications and patents covered by Rutgers/UMDNJ
Patent Rights shall be paid by Licensee. In addition, upon presentation of
appropriate evidence of such expense, Licensee shall pay all past patent
prosecution costs for the Rutgers/UMDNJ Patent Rights incurred by Rutgers/UMDNJ
prior to the execution of this Agreement which Rutgers/UMDNJ estimates to be
approximately $23,561.52 based on information currently available to
Rutgers/UMDNJ, which amount shall be due within sixty (60) days of the execution
of this Agreement. Current and future costs shall be payable by Licensee within
sixty (60) days of the billing date. If bills in excess of $10,000 remain
outstanding for more than such 60-day period after notice to Licensee then
Rutgers/UMDNJ may send a notice of termination to Licensee referencing such
bills and enclosing copies of invoices against which the same are payable, and
unless Licensee pays such bills within ninety (90) days after the effective date
of giving the termination notice in accordance with Article 19 or is contesting
such bills in good faith, Rutgers/UMDNJ may terminate this Agreement at the end
of such 90-day period.

         15.5 Rutgers/UMDNJ shall, at the request of Licensee, file, prosecute,
and maintain patent applications and patents covered by Rutgers/UMDNJ Patent
Rights in foreign countries if available. Licensee consents to the filing of all
PCT and foreign patent applications that have already been filed

                                       19

<PAGE>



as of the effective date of this Agreement. Licensee shall notify Rutgers/UMDNJ
within six (6) months of the filing of the corresponding United States
application (or, with respect to United States applications pending as of the
date of execution of this Agreement, within three (3) months of the execution of
this Agreement) of the foreign jurisdictions in which it wishes to seek
corresponding patent protection. This notice shall be in writing. The absence of
such a notice from Licensee shall be considered by Rutgers/UMDNJ to be an
election not to request foreign rights.

         15.6 Licensee's obligation to underwrite and to pay patent prosecution
costs shall continue for so long as this Agreement remains in effect, provided,
however, that:

         (a) Licensee shall have no such obligation with respect to patent
         prosecutions in foreign jurisdictions other than those in process as of
         the date of this Agreement or which are designated in a notice to
         Rutgers/UMDNJ pursuant to paragraph 15.5; and

         (b) Licensee may terminate its obligations with respect to any given
         patent application or patent upon three (3) months' written notice to
         Rutgers/UMDNJ. Rutgers/UMDNJ shall use reasonable efforts to curtail
         patent costs when such a notice is received from Licensee. Licensee
         shall promptly pay patent costs incurred prior to the expiration of
         such three-month period which cannot be so curtailed. Commencing at the
         expiration of such three-month period, Rutgers/UMDNJ may continue
         prosecution and/or maintenance of such application(s) or patent(s) at
         its sole discretion and expense, and Licensee shall have no further
         right or licenses thereunder or related to Rutgers/UMDNJ Technology in
         the relevant jurisdiction.

         15.7 Rutgers/UMDNJ shall have the right to file patent applications at
its own expense in any country or countries in which Licensee has not elected to
secure patent rights or in which Licensee's patent rights hereunder have
terminated, and such applications and resultant patents shall not be subject to
this Agreement and may be freely licensed by Rutgers/UMDNJ to others together
with Rutgers/UMDNJ Technology in the relevant jurisdiction.

         15.8 Rutgers/UMDNJ shall not abandon any patent applications or issued
patent comprising Rutgers/UMDNJ Patent Rights or otherwise fail to prosecute
diligently or maintain any Rutgers/UMDNJ Patent Rights except following at least
forty-five (45) days written notice to Licensee, following which Licensee shall
have the right, but not the obligation, to commence or continue such prosecution
and to maintain any such Rutgers/UMDNJ Patent Rights under its own control and
expense.


                               16. PATENT MARKING

         16.1 Licensee shall mark all Licensed Products made, used, or sold
under the terms of this Agreement, or their containers, in accordance with the
applicable patent marking laws.

                             17. PATENT INFRINGEMENT

         17.1 In the event that Licensee shall learn of the infringement of any
patent or right licensed under this Agreement, Licensee shall call
Rutgers/UMDNJ's attention thereto in writing. Both parties to this Agreement
agree that during the period and in a jurisdiction where Licensee has exclusive
rights under this Agreement, neither will notify a third party of the
infringement of any of Rutgers/UMDNJ Patent Rights or such other intellectual
property rights without first obtaining consent of the other party, which
consent shall not be unreasonably withheld. Both parties shall use their best
efforts in cooperation with each other to terminate such infringement without
litigation. Rutgers/UMDNJ shall have the first option to undertake the
enforcement of the Rutgers/UMDNJ Patent Rights, provided, however, that Licensee
may join with Rutgers/UMDNJ and its counsel in prosecuting such legal action,
provided, however, that if the use of counsel chosen by Rutgers/UMDNJ would
present such counsel with a conflict of interest then Licensee may obtain
counsel of its choice at its sole expense.

         17.2 Licensee may request that Rutgers/UMDNJ take legal action against
the infringement of Rutgers/UMDNJ Patent Rights licensed under this Agreement.
Such request shall be made in writing and shall include reasonable evidence of
such infringement and damages to Licensee. If Rutgers/UMDNJ does not commence a
diligent legal challenge within sixty (60) business days after such request (or
immediately in the event Licensee requests that Rutgers/UMDNJ seek provisional
relief and reasonably demonstrates that such relief is required), and the
infringing activity has not been abated within such time, or if at any time
thereafter Rutgers/UMDNJ does not persist in such diligent legal challenge until
the infringement has been abated, Licensee may, if the infringement occurred in
a jurisdiction where Licensee had exclusive rights under this Agreement, have
control over the prosecution of legal actions relating thereto. However, in the
event Licensee elects to bring suit in accordance with this paragraph 17.2,
Rutgers/UMDNJ may thereafter join with Licensee and its counsel in prosecuting
such legal action, provided, however, that if the use of counsel chosen by
Rutgers/UMDNJ would present such counsel with a conflict of interest then
Rutgers/UMDNJ may obtain counsel of its choice at its sole expense.

         17.3 Recoveries or reimbursements from any such litigation or
settlement within the scope of paragraph 17.2 in a jurisdiction in which
Licensee had exclusive rights under this Agreement at the time of the
infringement shall be first applied to reimburse Licensee and/or Rutgers/UMDNJ
for out-of-pocket litigation costs (with respect to Licensee, to the extent not
theretofore credited against royalties in accordance with paragraph 17.5) and
then to Rutgers/UMDNJ for any royalties past due or withheld pursuant to
paragraph 17.5. Any remaining recoveries or reimbursements shall be divided
between Licensee and Rutgers/UMDNJ at a rate of 15% to Rutgers/UMDNJ and 85% to
Licensee.

         17.4 In the event that a claim or suit is asserted or brought against
Licensee alleging that the manufacture or sale of any Licensed Product by
Licensee or its sublicensees, or the use of such Licensed Product by any
customer of any of the foregoing, infringes proprietary rights of a third party,
Licensee shall give written notice thereof to Rutgers/UMDNJ. Licensee may, in
its sole

                                       21

<PAGE>



discretion, modify such Licensed Product to avoid such infringement and/or may
settle on terms that it deems advisable in its sole discretion, subject to
paragraph 17.6. Otherwise, Licensee shall have the right, but not the
obligation, to defend any such claim or suit. In the event Licensee elects not
to defend such suit, Rutgers/UMDNJ shall have the right, but not the obligation
to do so at its sole expense.

         17.5 [***] payable to Rutgers/UMDNJ hereunder for such country and
apply the same toward one-half of its actual, reasonable out-of-pocket
litigation costs. If one half of such litigation costs in such country exceed
50% of royalties payable to Rutgers/UMDNJ in any year in which such costs are
incurred than the amount of such costs, expenses and amounts paid in judgement
or settlement, in excess of such 50% of the royalties payable shall be carried
over and credited against royalty payments in future years for such country.

         17.6 Licensee shall not settle or compromise any suit in a manner that
imposes any obligations or restrictions on Rutgers/UMDNJ or grants any rights to
the Rutgers/UMDNJ Patent Rights without Rutgers' written permission, which
permission shall not be unreasonably withheld. Rutgers/UMDNJ shall not settle or
compromise any such suit in a manner that imposes any obligations or
restrictions on Licensee without Licensee's written permission, which permission
shall not be unreasonably withheld.

         17.7 In any action to enforce any of the Rutgers/UMDNJ Patent Rights,
either party, at the request and expense of the other party, shall cooperate to
the fullest extent reasonably possible. This provision shall not be construed to
require either party to undertake any activities, including legal discovery, at
the request of any third party except as may be required by lawful process of a
court of competent jurisdiction.

         17.8 Notwithstanding the foregoing, with respect to any country in
which a third-party commences a legal action in any country in which Licensee
has exclusive rights under this Agreement alleging that the practice of
Rutgers/UMDNJ Patent Rights infringes the third-party's patent rights, Licensee
shall withhold, pending final resolution of the litigation, [***]


                        18. INDEMNIFICATION AND INSURANCE

         18.1 Licensee shall indemnify, hold harmless and defend Rutgers/UMDNJ,
its governors, trustees, officers, employees, students, agents and the Inventors
against any and all claims, suits, losses, liabilities, damages, costs, fees and
expenses (including reasonable attorneys' fees) resulting from or arising out of
the exercise of this license or any sublicense. This indemnification shall
include, but is not limited to, any and all claims alleging products liability.
Notwithstanding the foregoing, Licensee shall not have responsibility to assume
the defense of any claim prosecuted against both Licensee and Rutgers/UMDNJ to
the extent there is an actual or potential conflict of interest requiring
separate representations (it being understood that Licensee shall nevertheless
remain responsible for indemnifying Rutgers/UMDNJ for defense costs to the
extent provided

                                       22

<PAGE>



herein). In the absence of such a conflict, any separate representation of
Rutgers/UMDNJ with respect to a claim asserted against both Licensee and
Rutgers/UMDNJ shall, if at Rutgers/UMDNJ's request, be at Rutgers/UMDNJ's
expense.

         18.2 Licensee shall, from the commencement of Company sponsored human
clinical trials, at its sole cost and expense, insure its activities in
connection with this Agreement and will maintain and keep in force, with
insurers acceptable to Rutgers/UMDNJ, or an equivalent program of self insurance
acceptable to Rutgers/UMDNJ the following types of insurance:


         [***]


         (b) It is expressly understood and agreed, however, that the insurance
         coverage and limits stated in (a) above shall not in any way limit the
         liability of Licensee and that the required insurance shall be primary
         coverage. Any insurance Rutgers/UMDNJ may purchase will be excess and
         noncontributory. Licensee's liability insurance will be endorsed to
         specifically name Rutgers/UMDNJ as an additional insured and provide as
         primary coverage.

         (c) Licensee shall furnish Rutgers/UMDNJ with a Certificate of
         Insurance evidencing the coverage and limits required pursuant to (a)
         above. The Certificate of Insurance shall:

                  (i) Provide for thirty (30) day advance written notice to
                  Rutgers/UMDNJ of cancellation or alteration of policy limits;

                  (ii) Indicate that Rutgers/UMDNJ has been endorsed as an
                  additional insured under the coverages referred to above;

                  (iii) Include a provision that the insurance will be primary
                  and any valid and collectible insurance or program of
                  self-insurance carried or maintained by Rutgers/UMDNJ shall be
                  excess and noncontributory.

         18.3 Rutgers/UMDNJ shall promptly notify Licensee in writing of any
claim or suit brought against Rutgers/UMDNJ in respect of which Rutgers/UMDNJ
intends to invoke the provisions of paragraph 18.1. Licensee shall keep
Rutgers/UMDNJ informed on a current basis of its defense of any claims pursuant
to paragraph 18.1. Rutgers/UMDNJ shall provide full cooperation to Licensee in
such defense and make available to Licensee all documentary and other evidence
in its possession with respect thereto. Licensee shall not settle any claim or
suit on terms that impose any obligations or restrictions on Rutgers/UMDNJ
without Rutgers/UMDNJ written permission, which permission shall not be
unreasonably withheld.

         18.4 Notwithstanding the foregoing, if the requirements of this Article
18 are not consistent with general industry norms or good business practices at
the time, Rutgers/UMDNJ agrees to negotiate in good faith to modify this Article
18; provided, however, that if the Licensee

                                       23

<PAGE>



using good faith reasonable efforts can not obtain the insurance required by
this Article 18 at rates which are prudent given the Licensee's financial
position as determined by the Board of Directors of Licensee at the time such
insurance is required then Rutgers/UMDNJ may modify or waive the requirements of
this Article 18 until the earlier of:

         (a) a determination by the Board of Directors of the Licensee that
         Licensee's financial position permits it to obtain the insurance
         required by this Article 18; and

         (b) the First Commercial Sale of any of Licensed Product by Licensee or
         its sublicensees.


                                   19. NOTICES

         19.1 Any notice or payment required to be given to either party shall
be deemed to have been properly given and to be effective on the date of
delivery if delivered in person, by facsimile where confirmed by the receiving
party or if mailed by registered or certified mail (return receipt requested) to
the respective addresses given below, or to such other address as it shall

         20.1 This Agreement is binding upon and shall inure to the benefit of
Rutgers/UMDNJ, its successors and assigns, but shall be personal to Licensee and
assignable by Licensee only with the written consent of Rutgers/UMDNJ, which
consent shall not be unreasonably withheld. Notwithstanding the foregoing,
Licensee may, without such consent, assign this Agreement in whole or in part
to:

         (a) a purchaser, merging or consolidating corporation, or acquiror of
         substantially all of Licensee's assets or business and/or pursuant to
         any reorganization of Licensee qualifying under section 368 of the

         time; or

         (b) any Affiliate of Licensee so long as Licensee remains responsible
         as guarantor for the performance of this Agreement.


                                21. LATE PAYMENTS

         21.1 In the event any amounts due Rutgers/UMDNJ hereunder, including
but not limited to royalty payments, fees and patent cost reimbursements, are
not received when due, Licensee shall pay to Rutgers/UMDNJ interest charges at a
rate of four percent (4%) over the prime lending rate most recently announced by
Citibank, N.A. Such interest shall be calculated from the date payment was due
until actually received by Rutgers/UMDNJ.


                                   22. WAIVER

         22.1 It is agreed that no waiver by either party hereto of any breach

                             23. FAILURE TO PERFORM

         23.1 In the event of a failure of performance due under the terms of
this Agreement and if it becomes necessary for either party to undertake legal
action against the other on account thereof, then the prevailing party shall be
entitled to reasonable attorney's fees in addition to costs and necessary
disbursements.


                               24. GOVERNING LAWS

         24.1 THIS AGREEMENT SHALL BE INTERPRETED AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF NEW JERSEY, but the scope and validity of any
patent or patent application shall be governed by the applicable laws of the
country of such patent or patent application.


                         25. FOREIGN GOVERNMENT APPROVAL
                                 OR REGISTRATION

         25.1 If this Agreement or any associated transaction is required by the
law of any nation to be either approved or registered with any governmental
agency, Licensee shall assume all legal obligations to do so and the costs in
connection therewith.


                             26. EXPORT CONTROL LAWS

         26.1 Licensee shall observe all applicable United States and foreign
laws with respect to the transfer of Licensed Products and related technical
data to foreign countries, including, without limitation, the International
Traffic in Arms Regulations (ITAR) and the Export Administration Regulations.


                               27. CONFIDENTIALITY

         27.1 Any proprietary or confidential information relating to the
Invention (including but not limited to Rutgers/UMDNJ Technology and patent
prosecution documents relating to Rutgers/UMDNJ Patent Rights) collectively
constitute "Rutgers/UMDNJ Confidential Information." Licensee agrees that it
will not use Rutgers/UMDNJ Confidential Information for any purpose unrelated to
this Agreement or the Research Agreement, and will hold it in confidence during
the term of this Agreement and for a period of five years after the termination
or expiration date of this Agreement. Licensee shall exercise with respect to
such Rutgers/UMDNJ Confidential Information the same degree of care as Licensee
exercises with respect to its own confidential or proprietary information of a
similar nature, and shall not disclose it or permit its disclosure to any third
party (except to those of its employees, consultants, or agents who are bound by
the same obligation of

                                       26

<PAGE>



confidentiality as Licensee is bound by pursuant to this Agreement). However,
such undertaking of confidentiality by Licensee shall not apply to any
information or data which:

         (a) Licensee receives at any time from a third party lawfully in
         possession of same and having the right to disclose same;

         (b) is, as of the date of this Agreement, in the public domain, or
         subsequently enters the public domain through no fault of Licensee;

         (c) is independently developed by Licensee as demonstrated by written
         evidence without reference to information disclosed to Licensee by
         Rutgers/UMDNJ;

         (d) is disclosed pursuant to the prior written approval of
         Rutgers/UMDNJ; or

         (e) is required to be disclosed pursuant to law or legal process
         (including, without limitation, to a governmental authority) provided,
         in the case of disclosure pursuant to legal process, reasonable notice
         of the impending disclosure is provided to Rutgers/UMDNJ and
         Rutgers/UMDNJ has agreed to such disclosure in writing or has exhausted
         its right to contest such disclosure.

         27.2 Any proprietary or confidential information or data acquired (from
a source other than Rutgers/UMDNJ) or developed by Licensee and disclosed to
Rutgers/UMDNJ under this Agreement constitute collectively "Licensee's
Confidential Information". Rutgers/UMDNJ agrees that it will not use Licensee's
Confidential Information for any purpose unrelated to this Agreement or the
Research Agreement and that it will hold Licensee's Confidential Information in
confidence during the term of this Agreement and for a period of five years
after the termination or expiration date of this Agreement. Rutgers/UMDNJ shall
exercise with respect to such Licensee Confidential Information the same degree
of care as Rutgers/UMDNJ exercises with respect to its own confidential or
proprietary information of a similar nature, and shall not disclose it or permit
the disclosure of Licensee's Confidential Information to any third party (except
to those of its employees, consultants, or agents who are bound by the same
obligation of confidentiality as Rutgers/UMDNJ is bound by pursuant to this
Agreement). However, such undertaking of confidentiality shall not apply to any
information or data which:

         (a) Rutgers/UMDNJ receives at any time from a third party lawfully in
         possession of same and having the right disclose same;

         (b) is, as of the date of this Agreement, in the public domain, or
         subsequently enters the public domain through no fault of
         Rutgers/UMDNJ;

         (c) is independently developed by Rutgers/UMDNJ as demonstrated by
         written evidence without reference to information disclosed to
         Rutgers/UMDNJ by Licensee;

         (d) is disclosed pursuant to the prior written approval of Licensee; or

                                       27

<PAGE>



         (e) is required to be disclosed pursuant to law or legal process
         (including, without limitation, to a governmental authority) provided,
         in the case of disclosure pursuant to legal process, reasonable notice
         of the impending disclosure is provided to Licensee and Licensee has
         agreed to such disclosure in writing or has exhausted its right to
         contest such disclosure.


                28. INFRINGEMENT UNDER DRUG PRICE COMPETITION ACT

         28.1 In the event either party receives notice pertaining to any patent
included within Rutgers/UMDNJ Patent Rights pursuant to the Drug Price
Competition and Patent Term Restoration Act of 1984 (Public Law 98-417,
hereinafter, "the Act"), including but not necessarily limited to notices
pursuant to Sections 101 and 103 of the Act from persons who have filed an
Abbreviated New Drug Application ("ANDA") or a "paper" New Drug Application
("paper NDA"), or in the case of an infringement of Rutgers/UMDNJ Patent Rights
as defined in Section 271(e) of Title 35 of the United States Code, such party
shall notify the other party promptly but in no event later than ten (10) days
after receipt of such notice.

         28.2 If Licensee wishes action to be taken against such infringement,
as provided in the Act, Licensee shall request such action by written notice to
Rutgers/UMDNJ. Within [thirty (30)] days of receiving said request,
Rutgers/UMDNJ will give written notice to Licensee of its election to:

         (a) commence suit on its own account; or

         (b) refuse to participate in such suit.

If Rutgers/UMDNJ elects not to bring such suit and the infringement occurred
during a period that Licensee had exclusive rights under this license, then
Licensee may thereafter bring suit for patent infringement as provided by the
Act. However, in the event Licensee elects to bring suit in accordance with this
paragraph, Rutgers/UMDNJ may thereafter join such suit at its own expense.

         28.3 The provisions of paragraphs 17.3 through 17.6 shall likewise
apply to any legal action brought under this Article 28.

         28.4 Rutgers/UMDNJ hereby authorizes Licensee to include in any NDA for
a Licensed Product a list of patents included within Rutgers/UMDNJ Patent Rights
identifying Rutgers/UMDNJ as patent owner.


                                 29. ARBITRATION

         Except with respect to disputes relating to product liability and other
third party claims, any dispute arising from or relating to this Agreement shall
be determined before a tribunal of three arbitrators in New York, New York in
accordance with the rules of the American Arbitration

                                       28

<PAGE>



Association. One arbitrator shall be selected by Rutgers/UMDNJ, one arbitrator
shall be selected by Licensee and the third arbitrator shall be selected by
mutual agreement of the first two arbitrators. The costs of such arbitration
shall be borne by the nonprevailing party. Judgment on the arbitration award may
be entered by any court of competent jurisdiction.


                                30. MISCELLANEOUS

         30.1 The headings of the several articles are inserted for convenience
of reference only and are not intended to be a part of or to affect the meaning
or interpretation of this Agreement.

         30.2 This Agreement will not be binding upon the parties until it has
been signed below on behalf of each party, in which event, it shall be effective
as of the date recited on page one.

         30.3 No amendment or modification hereof shall be valid or binding upon
the parties unless made in writing and signed on behalf of each party.

         30.4 This Agreement embodies the entire understanding of the parties
and shall supersede all previous communications, representations or
understandings, either oral or written, between the parties relating to the
subject matter hereof..

         30.5 In case any of the provisions contained in this Agreement shall be
held to be invalid, illegal or unenforceable in any respect, such invalidity,
illegality or unenforceability shall not affect any other provisions hereof, but
this Agreement shall be construed as if such invalid or illegal or unenforceable
provisions had never been contained herein.
