                   Subject to Completion, Dated June 25, 1997

                                7,047,788 Shares
                             AVAX Technologies, Inc.
                                  Common Stock

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) 616,449 shares of the Company's
common stock, par value $.004 per share (the "Common Stock"); (ii) 6,382,106
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) 49,233 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
advise the Selling Securityholders of the requirement for delivery of this
Prospectus in connection with any sale of the shares offered hereby.

The Company is in the research and development stage, has not had any operating
revenues, and at March 31, 1997, had an accumulated deficit of approximately
$4,216,187. The Company is continuing to incur losses and expects to incur
significantly increasing additional losses for the foreseeable future.

   
The Company has been granted approval for initial listing and quotation of the
Common Stock on the Nasdaq SmallCap Market under the symbol "AVAX." Prior to the
Offering, shares of Common Stock that were freely tradeable pursuant to Rule
144(k) under the Securities Act of 1933 have been traded on the OTC Bulletin
Board Service (the "OTC Bulletin Board") under the symbol "AVXT". The last
reported sale price of the Common Stock on the OTC Bulletin Board on June 24,
1997, was $5.50 per share. The prices of 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," "Description of Securities" and "Plan of
Distribution." There can be no assurance that an active trading market in the
Company's securities will develop or be sustained.

STATEMENTS AND NOTES THERETO APPEARING ELSEWHERE IN THIS PROSPECTUS, INCLUDING,
WITHOUT LIMITATION, THE INFORMATION UNDER "RISK FACTORS," OR INCORPORATED HEREIN

                                 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.
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 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. David Berd, the inventor of the AC Vaccine technology, 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 development
program, which includes Phase III 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.

                                       3
<PAGE>


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 myelogenous 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. Berd.

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
                                    Securityholders" and "Description of Securities."

                                  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
March 31, 1997, the Company's accumulated deficit was approximately $4,216,187.
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-Vax(TM) 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-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.

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."

<PAGE>


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
<PAGE>

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. David Berd, the inventor
of the AC Vaccine technology, 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
development program, which includes Phase III 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, AND 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 June 25,
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 and include, among others,
Schering Plough Corporation, Chiron Corporation, Bristol-Myers Squibb and
Johnson & Johnson. 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.

CONTROL BY CURRENT OFFICERS, DIRECTORS AND PRINCIPAL STOCKHOLDERS

   
The Company's directors, executive officers and principal stockholders
beneficially own approximately 42.64% 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 June 25, 1997, 3,467,229 shares of Common Stock were issued and
outstanding of which the Company believes that 2,152,654 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 2,152,654
"restricted" shares of Common Stock, approximately 1,150,814 shares of Common
Stock are presently eligible for sale and an additional (i) approximately
567,421 shares of Common Stock will be eligible for sale in the latter part of
1997 and (ii) approximately 1,132,545 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 one year 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 two years is entitled to sell such shares under Rule 144(k) without
regard to the volume limitations described above.

In addition, the Company has issued and outstanding or issuable warrants and
options to purchase an aggregate of 1,590,065 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
<PAGE>

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 approval for initial listing and quotation of the
Common Stock on the Nasdaq Small Cap Market. 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 approved for initial listing and quotation on the Nasdaq
SmallCap Market, continued inclusion of the Common Stock on the Nasdaq SmallCap
Market pursuant to recently proposed stricter standards requires that: (i) the
Company have net tangible assets of $2,000,000, or a market capitalization of
$35 million or more, or net income in two of the three most recent fiscal years
of at least $500,000; (ii) the Company's public float have a market value of at
least $1 million and a public float of at least 500,000 shares; (iii) the
minimum bid price for the Common Stock be at least $1.00 per share; (iv) the
Common Stock have at least two active market makers and be held of record by at
least 300 shareholders and (v) the Company adhere 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


                                       16
<PAGE>

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 271,768 have been issued as Series B Preferred
Stock 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 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

                                       17
<PAGE>



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 were convertible at the option of the
holders thereof into shares of Common Stock, at an initial conversion rate of 25
shares of Common Stock per share of Series B Preferred Stock, corresponding to a
conversion price equal to $4.00 per share (the "Initial Conversion Price"). As
of June 11, 1997, 13,250 shares of Series B Preferred Stock had been converted
to Common Stock. The Initial Conversion Price was adjusted effective June 11,
1997, because the average closing bid price of the Common Stock for the 30
consecutive trading days immediately preceding such date was less than $5.40.
The average was, in fact, $5.175 per share. Accordingly, the conversion price
was adjusted to $3.83 per share, which corresponds to a new conversion rate of
26.0875 shares of Common Stock per share of Series B Preferred Stock. The
conversion price (and, consequently the number of shares of Common Stock
issuable upon conversion) is subject to further adjustment upon the occurrence
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.

                                 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.

                     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 approximately $4,216,187 as of March
31, 1997. 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 myelogenous 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" and "Manufacturing and Marketing."

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 myelogenous 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
myelogenous 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 at a rate in excess of 6% annually, melanoma affects over
200,000 people in the United States, with approximately 38,000 new cases
diagnosed in 1996.
    

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; and
    

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
development program, which includes Phase III 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 have
proven effective on animal models during preclinical studies, and, although
there can be no assurance, the Company believes that they may be effective on
humans. 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 unique activity against
solid


                                       26
<PAGE>

tumors 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
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 entered into in November 1995, 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 in December
1996, 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 co-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 in February
1997, 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


                                       27
<PAGE>

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 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 issued
229,121.5 shares of Common Stock 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 has also committed to the
issuance to Rutgers of warrants to purchase 125,000 shares of Common Stock at a
price of $8.24 per share. Such warrants are exercisable upon the achievement of
certain development-related milestones. The first 75,000 of such warrants will
expire in 2006 and the final 50,000 of such warrants will expire in 2011. These
warrants will provide for cashless exercise, piggyback registration rights and
certain anti-dilution rights.

The Company 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 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

                                       28
<PAGE>

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."

    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 and
biotechnology companies with commitments to oncology or antiviral research,
development and marketing, including, without limitation, Schering Plough
Corporation, Chiron Corporation, Bristol-Myers Squibb and Johnson & Johnson;
(ii) smaller biotechnology companies with similar strategies, including IDEC
Pharmaceuticals, Inc., Biomira Diagnostics, Inc. and Somatogen, Inc.; 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, without limitation, Ribi ImmunoChem Research, Inc.
and Progenics, Inc., 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
myelogenous leukemia (AML) and therefore may not be as limited as certain other
approaches.
    


                                       29
<PAGE>


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.

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" "--Dependence on Others for Clinical
Development of, and Regulatory Approvals for Manufacturing and Marketing of
Pharmaceutical Products."

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

                                       30
<PAGE>

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 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

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) or any other AC Vaccine technology.

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 June 25, 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. Its other consultants, scientific advisors, part-time officers
and directors 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, and Regulatory Approvals for, and Manufacturing and Marketing of
Pharmaceutical Products" and "Certain Transactions."

LEGAL PROCEEDINGS

The Company is not aware of any pending or threatened legal actions which may
have a material adverse affect on the Company's business.

</TABLE>

JEFFREY M. JONAS, M.D., has been the Chief Executive Officer, President and
Director of the Company since June 1, 1996. Prior to joining the Company, from
1994 to 1996, Dr. Jonas was the Vice President of Clinical Development and the
Chief Medical Officer of Upjohn Laboratories. From 1991 to 1994, he was the Vice
President of Worldwide Pharmaceutical Regulatory Affairs, the Director of
Psychopharmacology and the Director of Clinical Development III for Upjohn
Company. Prior thereto, Dr. Jonas was a research and clinical
psychopharmacologist in the Boston area. Dr. Jonas has authored a book on
Prozac(TM), and over 100 scientific articles, abstracts and book chapters. Dr.
Jonas received his M.D. from Harvard Medical School in 1979 and a B.A. in

SCIENTIFIC ADVISORY BOARD

The Company has a Scientific Advisory Board that consists of individuals with
extensive experience in the Company's fields of interest. It is expected that
the Scientific Advisory Board members will meet as a board with management and
key scientific employees of the Company on a semi-annual basis and in smaller
groups or individually on an informal basis. The Company anticipates that the
Scientific Advisory Board members will assist the Company in identifying
scientific and product development opportunities, in reviewing and evaluating
scientists and other employees. Presently, the Scientific Advisory Board members
consists of:

<TABLE>

David Berd, M.D. -- Chairman                Clinical Oncologist at the Jefferson Cancer Center of TJU and
                                            Inventor of the Company's AC Vaccine technology.
Edmond J. LaVoie, Ph.D.                     Professor of Medicinal Chemistry and Chairman of the Department of
                                            Pharmaceutical Chemistry at Rutgers University.
Margalit Mokyr, Ph.D.                       Professor of Biochemistry at the University of Illinois College of

                                            from September 1995 to March 1996. Former Director of Technology
                                            Transfer and Adjunct Professor at the Rockefeller University.

</TABLE>

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).

   
Drs. LaVoie, Mokyr and Safe each recently entered into a Scientific Advisory
Board Agreement with the Company, where they agreed to serve on the Scientific
Advisory Board for a period of two years, subject to automatic annual renewal
periods. Pursuant to their respective agreements with the Company, each such SAB
member shall receive $2,000 per meeting, and may, in the discretion of the Board
of Directors of the Company or Compensation Committee thereof, receive
additional compensation in the form of options to purchase shares of Common
Stock of the Company or otherwise.

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.

BOARD COMPENSATION

Currently, directors of the Company do not receive compensation for service on
the Board of Directors or any committee thereof but are reimbursed for travel
expenses incurred in attending board and committee meetings. The Company may
retain additional board members in the future. The Company expects that in the
future it will compensate its directors on a per meeting basis and through the
granting of stock options. Certain of the directors may have consulting
agreements and/or received stock grants in consideration for services rendered
to the Company, other than services rendered as members of the Board. See
"Executive Compensation" and "Certain Transactions."

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
12, 1996, the Company and the Placement Agent entered into a Financial Advisory
Agreement, pursuant to which the Placement Agent will act as the Company's
financial advisor. Such engagement provides that the Placement Agent will
receive a monthly retainer of $4,000 per month for a minimum of 24 months, plus
expenses and success fees.

On October 20, 1995, the Company entered into an Engagement & Technology
Acquisition Agreement with The Castle Group, LLC ("The Castle Group"), which may
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 229,121.5 shares of Common Stock. In connection
therewith, The Castle Group and its designees were granted and sold 916,485.5
shares of Common Stock of the Company at a price of $.004 per share. Prior to
the acquisition of the TJU License, the Company had no technological assets
other than that discussed below.

   
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 June 23, 1997 was $12.50 and $19.625, respectively.
    

Dr. Lindsay A. Rosenwald, a substantial shareholder of the Company, is the
Chairman and sole shareholder of each of the Placement Agent and Paramount
Capital Investments, LLC. Dr. Rosenwald is also Chairman of the Board and a
principal stockholder of Interneuron. Dr. Rosenwald personally collateralized
loans to the Company from NatWest Bank N.A., pursuant to which the Company
incurred principal and interest indebtedness of approximately $55,000. Such
indebtedness was paid in full as of June 30, 1996. Dr. Rosenwald also extended a
line of credit to the Company. As of June 30, 1996, the Company paid the
outstanding principal amount and accrued interest under such line of credit,
which was approximately $250,000. In addition, in 1995 and 1996, Paramount acted
as placement agent, pursuant to a placement agency agreement,


                                       39
<PAGE>

for a bridge financing for the Company as to which Paramount was paid $90,000 in
commissions and received warrants to purchase 31,250 shares of Common Stock. Two
of the investors in these bridge financings were private investment funds
managed by a company for which Dr. Rosenwald is President. Also, Michael S.
Weiss, Director and Secretary of the Company, is a Senior Managing Director of
Paramount and General Counsel of Paramount Capital Investments, LLC. Wayne
Rubin, at that time, the Treasurer of the Company, is Chief Financial Officer of
Paramount and Paramount Capital Investments, LLC. Dr. Carl Spana, a Director of
the Company, was at that time a Vice President of Paramount Capital Investments,
LLC. Dr. John K.A. Prendergast, also a Director of the Company, is a Managing
Director of Paramount Capital Investments, LLC.

In consideration of services rendered on behalf of the Company in connection
with the acquisition and negotiation of the Rutgers License, on February 13,
1997, the Company agreed to pay Samuel P. Wertheimer, Ph.D., $25,000, and Carl
Spana, Ph.D., $15,000. In addition, the Company agreed to issue to each of Drs.
Wertheimer and Spana warrants to purchase 6,375 shares of Common Stock at an
exercise price of $6.00 per share, exercisable for seven years. In consideration
of services rendered on behalf of the Company in connection with the acquisition
and negotiation of the Texas A&M License, on February 13, 1997, the Company
agreed to pay Fred Mermelstein, Ph.D., $40,000 and to issue to Dr. Mermelstein
warrants to purchase 12,750 shares of Common Stock at an exercise price of $6.00
per share, exercisable for seven years. Drs. Wertheimer and Mermelstein are
employees of Paramount Capital Investments, LLC. Dr. Spana is a Director of the
Company.

Pursuant to the Company's Certificate of Incorporation and Bylaws, the Company
has agreed to indemnify the Directors of the Company to the maximum extent
permissible under Delaware law.

                            DESCRIPTION OF SECURITIES

   
The Company is authorized to issue up to 50,000,000 shares of Common Stock, par
value $.004 per share, and 5,000,000 shares of preferred stock, par value, $.01
per share, of the Company. As of June 25, 1997, 3,467,229 shares of Common Stock
and 245,948 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 245,948 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 321,875 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."


                                       43
<PAGE>

SERIES B PREFERRED STOCK

   
The Board of Directors of the Company has authorized the issuance of up to
300,000, of which 245,948 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 25
shares of Common Stock based upon an initial conversion price of $4.00 per share
of Common Stock (the "Initial Conversion Price"). As of June 11, 1997, 13,250
shares of Series B Preferred Stock had been converted into shares of Common
Stock. The Initial Conversion Price was adjusted effective June 11, 1997,
because the average closing bid price of the Common Stock for the 30 consecutive
trading days immediately preceding such date was less than $5.40. The average
was, in fact, $5.175 per share. Accordingly, the conversion price was adjusted
to $3.83 per share, which corresponds to a new conversion rate of 26.0875 shares
of Common Stock per share of Series B Preferred Stock. The conversion price is
subject to further 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.
    

    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

                                       44
<PAGE>

securities of the Company senior to or on parity with the Series B Preferred
Stock, (ii) any alteration or change in the rights or 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 December
11, 1997.

In addition, in connection with the Company's application for listing and
quotation of the Common Stock on the Nasdaq Small Cap Market, pursuant to the
request of Nasdaq, the Company obtained from the officers and directors of the
Company, and certain employees of Paramount and its affiliates, agreements
locking-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. Such agreements may be waived in whole or in part at the option of the
Company.

1992 STOCK OPTION PLAN

A total of 437,500 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 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
granted to employees of the Company who at the time of the grant of such
incentive stock option own stock representing more than 10% of the voting power
of all classes of stock of the Company or any parent or subsidiary, must be at
least equal to 110% of the fair market value of such shares on the date of
grant. The AVAX Option Plan also requires that the exercise price of incentive
stock options granted to any other employee of the Company 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 granted by the Company must be
equal to 85% of the fair market value per share 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 June 25, 1997, options to purchase
30,000 shares of Common Stock were outstanding (of which approximately 27,222
were vested) at a weighted average price of $1.20 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.

(1)    Unless otherwise indicated, includes all shares of Common Stock issuable
       upon conversion of the Series B Preferred Stock at the reset conversion
       rate of $3.83 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.

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 11,930,048 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 7,047,788
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 approximately 1,150,814 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 437,500 shares of Common Stock have been reserved for
issuance, and has also reserved 623,872 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 2,152,654 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
2,152,654 "restricted" shares of Common Stock, approximately 1,150,814 shares of
Common Stock is eligible for sale and an additional (i) approximately 567,421
shares of Common Stock will be eligible for sale in 1997 and (ii) approximately
1,132,545 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 one year
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 two years is entitled
to sell such shares under Rule 144(k) without regard to the volume limitations
described above. 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.

For a description of the Company's outstanding warrants and options, see
"Description of Securities--1992 Stock Option Plan," "Other Options," and
"Warrants."

                              PLAN OF DISTRIBUTION

   
A total of 7,047,788 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.

The Company will advise the Selling Securityholders that no NASD member
participating in the offering of the shares of Common Stock being offered hereby
by the Selling Securityholders may receive compensation in excess of 8% of the
proceeds of the sale of such shares. In addition, the terms and arrangements of
any underwritten offering must be filed with the NASD for its review pursuant to
Section 2710 of the NASD's Corporate Financing Rules.

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, including, without limitation,
Regulation M.

                         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.
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

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 Rutgers Compounds) (see Note 3).

In February 1997, the Company entered into a license agreement with Texas A&M to
develop, commercially manufacture and sell products embodying a series of
compounds for the treatment of cancer (The Texas A&M 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.

   and for the period from January 12, 1990 (incorporation) to March 31, 1997)

Interim Financial Statements

The interim financial statements at March 31, 1997 and for the three months
ended March 31, 1996 and 1997 and for the period from January 12, 1990
(incorporation) to March 31, 1997 are unaudited; however, in the opinion of
management, all adjustments, consisting only of normal recurring accruals,
necessary for a fair presentation have been included. Results of interim periods
are not necessarily indicative of results to be expected for the entire year.

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.

Depreciation

Depreciation is computed using the straight-line method over the estimated
useful lives of the furniture and equipment, which range from three to 10 years.

Research and Development Costs

Research and development costs, including payments related to patents and
license agreements, are expensed when incurred.

Deferred Costs

Financing costs are deferred and amortized over the period of the related debt.

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. Pursuant to an amendment to the Company's Certificate of Incorporation
dated May 7, 1997, a second 1-for-2 reverse split of the Company's common stock
will be effected as of the close of business on May 13, 1997. All outstanding
share and per share amounts included in the accompanying financial statements
have been adjusted to reflect both 1-for-2 reverse stock splits.

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 $3.92 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 (320,663.5 shares at $3.92
per share) to repay certain debt of $1,257,000. Net income (loss) per share
would have been $(.72) for the year ended December 31, 1996 and $(.04) and
$(.26) for the three months ended March 31, 1996 and 1997, 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
sheets.

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.

                          (a development stage company)

   and for the period from January 12, 1990 (incorporation) to March 31, 1997)

2. Sale of the Product (continued)

      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 62,500 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. The present value of the amount payable to the
preferred stockholders, including the accretion of interest thereon, is
$1,044,101 at March 31, 1997, reduced by the payment of the first installment.

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 ($80,522) based on the fair value of
the Company's common stock ($.004 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. The present value of the amount payable to the
Former Officer, including the accretion of interest thereon, is $45,206 at March
31, 1997, reduced by the payment of the first installment.

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 458,243 shares of common stock at
$.004 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 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.

3. License and Research Agreements (continued)

In December 1996, the Company entered into an agreement with Rutgers for the
exclusive worldwide license to develop, manufacture and sell products embodying
the Rutgers 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 direct research costs 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 Rutgers 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
125,000 shares of common stock at a price of $8.24 per share based on the
achievement of certain development milestones. The first 75,000 warrants will
expire in 2006 and the final 50,000 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.

In addition, the Company is obligated to pay royalties on its worldwide net
sales revenue derived from the Rutgers Compounds and a percentage of all
revenues received from sublicensees of products derived from the Rutgers
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.

3. License and Research Agreements (continued)

In February 1997, the Company entered into an agreement with Texas A&M for the
exclusive worldwide license to develop, manufacture and sell products embodying
the Texas A&M Compounds. Under the terms of the license agreement, the Company
has agreed to fund research in the amount of approximately $108,000 per year for
the next three years. The Company is also obligated to pay certain milestone

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
severance arrangements (see Note 8), the Former Officer returned 111,330 shares
of common stock and options to purchase 62,500 shares of common stock. The
common stock returned was valued at $.004 per share. The common stock and
options returned were canceled.

In May 1995, in accordance with the terms of a settlement agreement (see Note
8), with a former officer and director of the Company, the Company agreed to
release and relinquish any claim it may have on certain intellectual property,
excluding the Product, in exchange for 196,618 shares of the Company's common
stock owned by her and her family. The common stock was valued at $.004 per
share and was canceled.

4. Equity Transactions (continued)

On September 13, 1995, the Company issued 402,490 shares of common stock to
officers of the Company at $.004 per share.

On November 20, 1995, the Company issued an aggregate of 458,243 shares of
common stock at $.004 per share to TJU and the Scientist (see Note 3). In
addition, on November 20, 1995, the Company issued, in aggregate, an additional
916,485 shares to a principal stockholder, a third party designated by the
principal stockholder, and an officer, at $.004 per share.

On March 24, 1996, the Company repurchased 77,901 shares of common stock
previously issued to an officer at $.004 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 $.004, 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 129,099 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 500
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.

The Series B preferred stockholders are entitled to voting rights equivalent to
the number of common shares into which their preferred shares are convertible.

to the holders of common stock, an amount per preferred share of $135 plus any
declared but unpaid dividends.

4. Equity Transactions (continued)

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 $4 per share
(the Initial Conversion Price), which amounts to 6,479,950 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.

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 321,875
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 $5.40. 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.

Staggered Lock-up


Pursuant to the original 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.

In March 1997, the Company completed a revision to the staggered Lock-up and
Conversion Reset provisions of the private placement. Approximately 94% of the
Series B preferred shares have agreed 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 who accepted 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.

Stock Options

In April 1992, the Board of Directors approved the 1992 Stock Option Plan (the
Plan), which, as amended, authorizes up to 437,500 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.

The following summarizes activity in the Plan:

                                                                   Options

          Balances at December 31, 1995 and 1996

                                                              ==================

All outstanding options were issued at an exercise price of $1.20 per share. At
December 31, 1996 and March 31, 1997, options to purchase 23,889 and 25,556
shares of common stock, respectively, were exercisable, and options to purchase
407,500 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 318,873 shares of common stock at $1.00 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 $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 252,500 shares of common stock at $1.00 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 $4 per share, the Company recorded $757,500 as
deferred compensation. Such deferred compensation is being amortized over four
years.

In March 1997, one other employee of the Company received options to purchase
52,500 shares of common stock at $6.00 per share, the closing market price on
the date of grant. Such options vest at a rate of 1/6 every six months over
three years and are exercisable for a period of seven years.

Warrants

The Company has issued warrants to purchase 88,769 (adjusted to comply with
anti-dilution provisions of the warrants) (June, July and September 1992), 7,750
(May 1993), and 90,000 (January, February and August 1995) shares of the
Company's common stock at a price of $2.60, $11.00 and $.04 per share,
respectively. These warrants are exercisable at any time and expire in 1997,
1998 and 2006, respectively. In January and February of 1996, the Company issued
warrants to purchase 97,500 shares of the Company's common stock at a price of
$.04 per share. Such warrants are exercisable at any time and expire in 2007.


In October 1996, the Company issued warrants to purchase 50,000 shares of common
stock at $6 per share, 25,000 of which were subsequently cancelled in April 1997
(see Note 7). In December 1996, the Company committed to the future issuance of
warrants to purchase 125,000 shares of the Company's common stock at a price of
$8.24 per share (see Note 3). In June and July of 1996, warrants to purchase
156,250 shares of common stock at $.04 per share were exercised.

In February 1997, the Company issued warrants to purchase 25,500 shares of
common stock at $6.00 per share.

Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
the Company's deferred tax assets and liabilities for federal income tax
purposes are as follows:

                                                    December 31,      March 31,

The valuation allowance at December 31, 1994 and 1995 was $1,161,000 and
$647,000, respectively.

Under Section 382 of the Tax Reform Act of 1986, the Company's net operating
loss carryforward could be subject to an annual limitation if it should be
determined that a change in ownership of more than 50% of the value of the
Company's stock occurred over a three-year period.

connection with these loans, the Company paid commissions totaling $54,000 and
issued warrants to purchase 15,000 shares of common stock at $.04 per share to

expenses. These amounts were recorded as accrued expenses in 1995. In May 1995,
the Company entered into an agreement with an officer, director and principal

Product, and the former director returned all shares of common stock of the

                     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 HTM Warrants (Exhibit 4.5), the Meyerson
Warrants (Exhibit 4.13), the Shear/Kershman and Castelli Warrants (Exhibit
4.16), the Rutgers Warrants (Exhibit 4.17) and the warrants to be issued to Drs.
Wertheimer, Spana and Mermelstein (Exhibit 4.15) 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 229,121.5 shares of 
         Common Stock 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 916,485.5
         of Common Stock of the Company at a price of $.004 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 were deemed to be exempt from registration under the 
         Securities Act in reliance on Section 4(2) thereof because such 
         issuances did not involve 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 nine persons or entities namely, The Aries 
         Domestic Fund, L.P., The Aries Fund, A Cayman Island Trust, Seymour 
         Buehler, Yonah J. Hamlet, M.D., Trustee FBO Yonah J. Hamlet, M.D. 
         Profit Sharing Plan Dtd. 1/1/86, South Ferry #2, L.P., Herman Tauber, 
         Myron M. Teitelbaum, M.D. William J. Vanden Heuvel and James D. 
         Wolfensohn ("Warrant Holders"), (i) bridge notes aggregating $1,000,000
         and (ii) warrants to purchase an aggregate of 156,250 shares of Common
         Stock at an exercise price of $.004 per share.  In June 1996, such 
         bridge notes were 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.
         ("Paramount") was issued warrants to purchase 31,250 shares of Common
         Stock at an exercise price of $.004 per share.  In connection with the 
         issuances of the Warrants and the Placement Warrants, each of the 
         Warrant Holders and Paramount 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 issuances of Common Stock had endorsed thereon legends 
         regarding restrictions on the transfer of the Common Stock.  The 
         issuances of the above referenced securities were deemed to be exempt 
         from registration under  the Securities Act in reliance on Section 4(2)
         thereof because such issuances did not involve 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 performed
         certain investment banking and financial advisory services on a non-
         exclusive basis for the Company (the "Meyerson Investment Banking 
         Agreement").  Pursuant to the Meyerson  Investment Banking Agreement, 
         which was terminated by the Company on April 17, 1997,  Meyerson 
         acquired warrants to purchase an aggregate of 50,000 shares of Common 
         Stock of the Company at an exercise price of $6.00 per share.  At the 
         time of the Company's termination, 25,000 of the Meyerson Warrants had 
         vested. The issuance of the Meyerson Warrants was deemed to be exempt 
         from registration under the Securities Act in reliance on Section 4(2)
         thereof because such issuance did not involve 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 125,000 shares
         of Common Stock at a price of $8.24 per share to Rutgers (the "Rutgers
         Warrants"). The issuance of the Rutgers Warrants was deemed to be
         exempt from registration under the Securities Act in reliance on
         Section 4(2) thereof because such issuance did not involve 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,
         in February 1997, the Company agreed to pay Samuel P. Wertheimer,
         Ph.D., $25,000 and to issue to Dr. Wertheimer warrants to purchase
         6,375 shares of Common Stock at an exercise price of $6.00 per share,
         exercisable for seven years (the "Wertheimer Warrants"). The issuance
         of the Wertheimer Warrants was deemed to be exempt from registration
         under the Securities Act in reliance on Section 4(2) thereof because
         such issuance did not involve 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. Moreover, Dr. Wertheimer represented to the Company that he
         was sophisticated and expert in financial matters.
    

     9.  In consideration of services rendered on behalf of the Company in
         connection with the acquisition and negotiation of the Rutgers License,
         in February 1997, the Company agreed to pay Carl Spana, Ph.D., $15,000
         and to issue to Dr. Spana warrants to purchase 6,375 shares of Common
         Stock at an exercise price of $6.00 per share, exercisable for seven
         years (the "Spana Warrants"). The issuance of the Spana Warrants was
         deemed to be exempt from registration under the Securities Act in
         reliance on Section 4(2) thereof because such issuance did not involve
         a public offering. In addition, Dr. Spana 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. Spana had adequate access to information
         about the Company through his negotiations with the Company of the
         terms of the Rutgers License and through his position as a Director of
         the Company.

   
     10. 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 to issue to Dr. Mermelstein warrants to purchase
         12,750 shares of Common Stock at an exercise price of $6.00 per share,
         exercisable for seven years (the "Mermelstein Warrants"). The issuance
         of the Mermelstein Warrants was deemed to be exempt from registration
         under the Securities Act in reliance on Section 4(2) thereof because
         such issuance did not involve 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
         affixed to the warrant certificates issued in such transactions. Dr.
         Mermelstein had adequate access, through his negotiations with the
         Company of the terms of the Texas A&M License, to information about the
         Company. Moreover, Dr. Mermelstein represented to the Company that he
         was sophisticated and expert in financial matters.
    

     11. In connection with services rendered by Ladenberg, Thalmann & Co., Inc.
         ("Ladenburg"), and D. H. Blair Investment Banking Corp. ("D. H.
         Blair"), as placement agents in the offering of Series A Preferred
         Stock conducted from June 1992 to September 1992 (the "Series A
         Offering"), the Company granted Ladenburg and D. H. Blair and/or their
         respective designees certain warrants ("Series A Placement Warrants")
         to purchase Common Stock at any time until June 26, 1997. In April
         1997, Ladenburg was issued 24,850.5 shares of Common Stock pursuant to
         the cashless exercise provision of its Series A Placement Warrants. The
         issuance of (i) the Series A Placement Warrants and (ii) the issuance
         of Common Stock upon the exercise of the Series A Placement Warrants,
         were deemed to be exempt from registration under the Securities Act in
         reliance on Section 4(2) thereof because such issuances did not involve
         a public offering. In addition, each of Ladenburg and D. H. Blair
         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. Ladenburg and D. H.
         Blair each had adequate access, through their negotiations with the
         Company as placement agents in the Series A Offering, to information
         about the Company. The shares of Common Stock were issued without
         restrictive legends pursuant to exemptions afforded by Rule 144(k).

     12. On April 17, 1997, the Company entered into an agreement with Hill,
         Thompson, Magid & Co. ("HTM"), pursuant to which HTM may perform
         certain investment banking and financial advisory services on a
         non-exclusive basis for the Company (the "HTM Investment Banking
         Agreement"). Among the services that might be provided by HTM are
         general advice and guidance on long-term strategic planning, assistance
         with debt and equity financings, identification of potential
         strategic/corporate partners, financial and transaction feasibility
         analysis, and mergers and acquisitions advisory services. Pursuant to
         the Investment Banking Agreement, the Company granted to HTM warrants
         to purchase an aggregate of 50,000 shares of Common Stock of the
         Company at an exercise price of $8.00 per share. The issuance of the
         HTM Warrants was deemed to be exempt from registration under the
         Securities Act in reliance on Section 4(2) thereof because such
         issuance did not involve a public offering. In addition, HTM
         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. HTM had adequate
         access, through its negotiations with the Company of the terms of the
         HTM Investment Banking Agreement, to information about the Company.

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.

Dear Sirs:

                  We have acted as counsel for AVAX Technologies, Inc., a

                   (i) 616,449 shares of common stock, par value $.004 per share
                   ("Common Stock");

                  (ii) 6,382,106 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

                                                                              2


                  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 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 616,449 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 6,382,106 shares of Common Stock issuable upon
conversion of currently outstanding shares of Series B Preferred Stock have been
duly authorized for issuance, and when issued upon conversion of the Series B

                  4. The aggregate of up to 37,983 shares of Common Stock

thereof or the use of the cashless exercise provision thereof will be legally
issued, fully paid and nonassessable.
