                  Subject to Completion, Dated November 6, 1996
    

                             AVAX TECHNOLOGIES, INC.
                        14,885,088 Shares of 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) 571,698 shares of the Company's
common stock, par value $.002 per share (the "Common Stock"); (ii) 12,959,900
shares of Common Stock issuable upon conversion of currently outstanding shares
of Series B Convertible Preferred Stock, par value $.01 per share, of the
Company ("Series B Preferred Stock"); and (iii) 1,353,490 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 placement agent of
the Series B Offering described herein (the "Series B Placement Warrants") and
(b) exercise of warrants issued to 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 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 $2,850,000. 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 Rules 10b-6 and 10b-7 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 June 30, 1996, had an accumulated deficit of approximately
$2,222,257. The Company is continuing to incur losses and expects to incur
significantly increasing additional losses for the foreseeable future.

   
Prior to the Offering, there has been no public market for the Common Stock and
there can be no assurance that such a market will develop or, if developed, that
it will be sustained. Certain market makers who have expressed an interest in
making a market in the Common Stock have applied for unlisted trading of the
Common Stock on the OTC Bulletin Board(R) Service (the "OTC Bulletin Board")
under the symbol "AVAX," and it is expected that such trading will be approved
by the OTC Bulletin Board shortly after the date of this Prospectus. The Company
also has applied for listing of the Common Stock on the National Association of
Securities Dealers Automated Quotation National Market(R) ("Nasdaq National
Market"). However, because of the absence of any prior trading history for the
Common Stock, Nasdaq has advised the Company that if and when the minimum bid
price for the Common Stock is quoted consistently on the OTC Bulletin Board for
$3.00 or more for a 20- to 30-trading day period, Nasdaq will consider the
Company's application. There can be no assurance that the minimum bid price will
be consistently quoted at $3.00 or more for a 20- to 30-trading day period on
the OTC Bulletin Board , or, if such trading occurs, that the Common Stock will
be listed subsequently on the Nasdaq National Market. 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."

                               PROSPECTUS SUMMARY

The following summary does not purport to be complete and is qualified in its
entirety by reference to the more detailed information and the financial
statements and notes thereto appearing elsewhere in this Prospectus, including,
without limitation, the information under "Risk Factors," or incorporated herein
by reference, and, accordingly, should be read in conjunction therewith.


                                 COMPANY SUMMARY

AVAX Technologies, Inc. ("AVAX" or the "Company"), is a development stage
biopharmaceutical company which intends to acquire rights to, and to develop,
technologies and products for the treatment of cancer. The Company initially
intends to focus its efforts primarily on the development of immunotherapies for
cancer, which 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 own immune system to
eliminate the cancer. This technology has emerged from research conducted at the
Jefferson Cancer Center of TJU. The technology 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, AC
MelaVax(TM), is currently undergoing a physician-sponsored human clinical trial
based on an experimental protocol at TJU Hospital as an outpatient,
post-surgical, adjunct therapy for the treatment of malignant 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 melanoma. In such
ongoing clinical trial at the Thomas Jefferson Medical Center, 150 malignant
melanoma patients have been treated post-surgically on an outpatient basis with
AC MelaVaxTM. In 62 patients with stage 3 melanoma for whom there has been
sufficient time for long-term follow-up, the four-year survival rate is
approximately 60%. This compares with the historical and control group survival
rate of approximately 20%, and the survival rate for treatment with high dose
alpha interferon of approximately 32%. The Company believes that the results to
date of the ongoing clinical trial represent the first substantial increase in
survival for malignant melanoma patients treated by immunotherapy. In the 150
patients treated in the study, the Company believes that only relatively minor
side effects, such as soreness and swelling at the site of the application of
the AC MelaVaxTM vaccine, have been witnessed to date.

Although TJU and Dr. David Berd, a clinical oncologist at the Jefferson Cancer
Center of TJU and inventor of the Company's AC Vaccine technology, have
conducted the ongoing clinical trial at TJU Hospital pursuant to an
FDA-approved, physician-sponsored Investigational New Drug Application ("IND"),
to date, the Company has not had any direct contact with the FDA concerning the
clinical results obtained with AC MelaVax(TM). However, it is the Company's
intention to use the results of the TJU clinical trial to support the submission
of a Company-sponsored IND to the FDA. The purpose of the IND submission will be
to seek FDA approval to enter AC MelaVax(TM) into Phase II/III or Phase III
multi-center clinical trials. Although there can be no assurance of such FDA
approval, if successful in obtaining clearance to commence such
Company-sponsored IND, 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 AC MelaVax(TM). The Company also may pursue a similar
regulatory approval and commercialization strategy for AC MelaVax(TM) in
Australia and certain countries in Europe 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.


AC MelaVax(TM) is a trademark of the Company. This Prospectus also includes
trademarks of other companies.


                                       3

The Company also believes that the AC Vaccine technology possibly may have
applications in the treatment of other cancers such as lung, breast, colon and
prostate cancers. Accordingly, in addition to continuing the clinical work on AC
MelaVax(TM) for melanoma, the Company also has entered into a sponsored research
agreement with TJU relating to the development of additional immunotherapies
based on the AC Vaccine technology. If appropriate, the Company intends to fund
the preclinical and initial clinical development of these technologies. In order
to contain costs, the Company may 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 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, Suite 930, Kansas City, Missouri
64111. Its telephone number at that address is (816) 960-1333.

                                    estimated expenses of this Offering, would
                                    be approximately $2,850,000. Whether, how
                                    and to what extent any of the Placement
                                    Warrants will be exercised, and whether the
                                    Placement Warrants are exercised for cash or

                                  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
June 30, 1996, the Company's accumulated deficit was approximately $2,222,257.
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 preclinical studies and clinical trials for the
AC MelaVaxTM product and other products that it may acquire or develop. The
Company's ability to achieve profitability depends upon, among other things, its
ability to discover and develop products, obtain regulatory approval for its
proposed products, and enter into agreements for product development,
manufacturing and commercialization. The Company's AC MelaVaxTM 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 AC MelaVaxTM 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."


                                       7
<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 early
the 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.

The Company's agreement with TJU, its licensor for the AC Vaccine technology,
does not contain any representations by the licensor 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 its 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 AC MelaVaxTM 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 AC MelaVax(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 their state and local counterparts.
Similar regulatory frameworks exist in other countries where the Company may
consider marketing its products. To date, while TJU has conducted its clinical
trials pursuant to an FDA-approved physician sponsored Investigational New Drug
Application ("IND"), the Company has not had any direct contact with the FDA
concerning AC MelaVax(TM). However, prior to marketing AC MelaVax(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 gene immunotherapy products
generally, and possibly lead to delays in the approval process for the Company's
potential products. See "Business--Government Regulation."

DEPENDENCE ON OTHERS FOR CLINICAL DEVELOPMENT OF, REGULATORY APPROVALS FOR, 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
assurance 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 AC MelaVax(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, it 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 and if established, that it will be able to successfully manufacture
products for sale at competitive prices. See "Business--Manufacturing and
Marketing."

DEPENDENCE ON LICENSE AND SPONSORED RESEARCH AGREEMENTS

The Company is dependent upon the TJU License as the basis of its proprietary
technology and is dependent upon a sponsored research agreement with TJU for its
research and development efforts. The TJU License requires the payment of an
up-front license fee, the use of due diligence in developing and bringing
products to market and to make certain milestone payments. 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. As the Company currently does
not have laboratory facilities, certain 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. If the Company does not meet its financial
obligations under either its license agreement or its sponsored research
agreement in a timely manner, the Company could lose the rights to its
proprietary technology or the right to have TJU conduct its research and
development efforts.

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 large part on its ability, on the ability
of its current licensor, TJU, 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. 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. Additionally, the foreign PCT application may be more
difficult to obtain and may take a longer amount of time and entail more costs
because this foreign PCT application was first filed on June 7, 1995, and may be
considered filed late. 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.


                                       10
<PAGE>

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. An adverse outcome could subject the Company to
significant liabilities to third parties, require the Company to obtain licenses
from third parties, or require the Company to alter its products or processes,
or cease altogether any related research and development activities or product
sales, any of which may have a material adverse effect on the Company's
business, results of operations and financial condition. See "Business --
Patents and Proprietary Technology."

To the extent that consultants, key employees or other third parties apply
technological information independently developed by them or by others to any of
the proposed projects of the Company, disputes may arise as to the proprietary
rights to such information which may not be resolved in favor of the Company.

LACK OF MANAGEMENT AND EMPLOYEES

The Company has only four full time employees, which includes its President and
Chief Executive Officer, Jeffrey M. Jonas, M.D., its Chief Financial Officer,
David L. Tousley, and its Executive Vice President, Ernest W. Yankee, Ph.D. The
Company's other officers, directors and scientific advisors work for the Company
on a part-time basis only and for the most part are involved with other
substantially full-time activities.

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 four 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. The loss of certain of these individuals, including,
without limitation, Jeffrey M. Jonas, M.D., the Company's President and Chief
Executive Officer, would have a material adverse effect on the Company. The
Company does not maintain key-man life insurance policies on any of such
personnel. 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.
Currently, the Company does not have "key-man" insurance for Dr. Jonas.

LACK OF FACILITIES

The Company currently has no permanent laboratories. With the exception of a
sponsored research program currently being conducted at TJU, it is currently
anticipated that the Company's research and product development activities will
require that the Company equip and maintain a laboratory facility for use by the
Company's scientists, if and when such persons are hired by the Company.

COMPETITION

The Company's proposed cancer immunotherapy business is characterized by
intensive research efforts and intense competition. Many companies, research
institutes, hospitals and universities are working to develop products and
processes in the Company's fields of research. Most of these entities have
substantially greater financial, technical, manufacturing, marketing,
distribution and other resources than the Company. Certain of such companies
have experience in undertaking testing and clinical trials


                                       11
<PAGE>

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; NO INSURANCE

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. The Company does not presently carry product
liability insurance. Prior to the first clinical testing by the Company of AC
MelaVax(TM), the Company's licensor requires that the Company obtain product
liability insurance. There can be no assurance that the Company will be able to
obtain such insurance or, if obtained, that such insurance can be acquired in
sufficient amounts to protect the Company against such liability or at a
reasonable cost. In the event that the Company is unable to obtain such
insurance, there can be no assurance that the Company will have sufficient
resources to satisfy any liability resulting from such product liability claims
or would be able to have its customers indemnify or insure the Company against
such claims. The Company is required to indemnify TJU against any product
liability claims incurred by them as a result of the products developed by the
Company. TJU has not made, and is 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.

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 effect 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 described in this Prospectus. 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


                                       12
<PAGE>

products or technologies and, even if suitable products or technologies are
identified, the Company does not expect to have sufficient resources to pursue
any such products or technologies in the foreseeable future.

Currently the Company's management and officers other than Jeffrey M. Jonas,
M.D., its President and Chief Executive Officer, devote only a portion of their
time to the business of the Company. In addition, certain of the directors and
part-time officers of the Company are full-time 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 63.80% of the outstanding shares of Common Stock.
Accordingly, the Company's executive officers, directors, principal stockholders
and certain of their affiliates have the ability to exert substantial influence
over the election of the Company's Board of Directors and the outcome of issues
submitted to the Company's stockholders. See "Principal Stockholders."
    

VOLATILITY OF STOCK PRICE

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

POTENTIAL ADVERSE EFFECT OF SHARES ELIGIBLE FOR FUTURE SALE

   
As of September 30, 1996, 6,222,316 shares of Common Stock were issued and
outstanding of which the Company believes that 4,386,409 shares of Common Stock
are "restricted securities" and under certain circumstances may, in the future,
be sold in compliance with Rule 144 (including 987,776 shares owned by persons
who may be the affiliates of the Company, but as to which there can be no
assurance, and whose shares therefore may not be restricted). Assuming the
availability of Rule 144, including the requirement that there is adequate
current public information with respect to the Company as contemplated by Rule
144, the Company believes that of the 4,386,409 "restricted" shares of Common
Stock, 987,776 shares of Common Stock are presently eligible for sale and an
additional 4,386,409 shares of Common Stock will be eligible for sale in 1997
pursuant to Rule 144, in each case subject to certain volume limitations and
manner of sale requirements imposed by Rule 144. In general, under
    


                                       13
<PAGE>

Rule 144, subject to the satisfaction of certain other conditions, a person,
including an affiliate of the Company, who beneficially owned restricted shares
of Common Stock for at least two years is entitled to sell, within any
three-month period, a number of shares that does not exceed the greater of one
percent of the total number of outstanding shares of the same class, or if the
Common Stock is quoted on the Nasdaq National Market, any other national
securities exchange or the OTC Bulletin Board, the average weekly trading volume
during the four calendar weeks immediately preceding the sale. A person who
presently is not and who has not been an affiliate of the Company for at least
three months immediately preceding the sale and who has beneficially owned the
shares of Common Stock for at least three years is entitled to sell such shares
under Rule 144 without regard to the volume limitations described above.

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.

NO PRIOR PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK PRICE

   
There is no public market for the Common Stock, and assuming the Common Stock's
approval for initial listing on the OTC Bulletin Board and/or on the Nasdaq
National Market, 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. The
Company believes that certain brokerage firms intend to act as market makers and
otherwise effect transactions in the Common Stock. To the extent these firms
participate, they may be a dominating influence in any market that might
develop, and the degree of participation by the 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 NATIONAL MARKET; POSSIBLE DELISTING FROM NASDAQ
NATIONAL MARKET; MARKET ILLIQUIDITY

   
Prior to the Offering, there has been no public market for the Common Stock and
there can be no assurance that such a market will develop or, if developed, that
it will be sustained. Certain market makers who have expressed an interest in
making a market in the Common Stock have applied for unlisted trading of the
Common Stock on the OTC Bulletin Board(R) Service (the "OTC Bulletin Board")
under the symbol "AVAX," and it is expected that such trading will be approved
by the OTC Bulletin Board shortly after the date of this Prospectus, although
there can be no such assurance. The Company also has applied for listing of the
Common Stock on the National Association of Securities Dealers Automated
Quotation National Market(R) ("Nasdaq National Market"). The Company believes
that it meets the criteria for such listing on such market, including, without
limitation: (i) total assets of at least $4 million; (ii) total stockholder
equity of $2 million; (iii) a market value of its publicly held shares of at
least $1 million; (iv) the Common Stock be held by at least 300 shareholders;
(v) at least two market makers; and
    


                                       14
<PAGE>

(vi) and an initial minimum bid price of at least $3.00. However, because of the
absence of any prior trading history for the Common Stock, Nasdaq has advised
the Company that if and when the minimum bid price for the Common Stock is
quoted consistently on the OTC Bulletin Board for $3.00 or more for a 20- to
30-trading day period, Nasdaq will consider the Company's application. There can
be no assurance that the minimum bid price will be consistently quoted at $3.00
or more for a 20- to 30-trading day period on the OTC Bulletin Board , or, if
such trading occurs, that the Common Stock will be listed subsequently on the
Nasdaq National Market. The prices of the Common Stock which may be obtained on
the OTC Bulletin Board or the Nasdaq National Market or 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.

Assuming the Nasdaq National Market listing of the Common Stock is approved
subsequently, continued inclusion of the Common Stock on the Nasdaq National
Market requires that: (i) the Company maintain at least $4,000,000 in net
tangible assets if it has sustained losses from continuing operations and/or net
losses in three of its four most recent fiscal years; (ii) a market value of its
publicly held shares of at least $1 million; (iii) the minimum bid price for the
Common Stock be at least $1.00 per share or, in the alternative, the market vale
of the Company's publicly held shares must be at least $3 million and the
Company have at least $4 million of net tangible assets; (iv) the public float
of the Common Stock consist of at least 200,000 shares; (v) the Common Stock
have at least two active market makers; and (vi) the Common Stock be held by at
least 400 holders or 300 round lots. If the Company is unable to satisfy such
maintenance requirements, the Common Stock may be delisted from the Nasdaq
National Market. In such event, trading, if any, in the Common Stock would
thereafter be conducted in the over-the-counter market in the "pink sheets" or
the OTC Bulletin Board. 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 the media's 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 Securities Exchange Act of 1934 (the "Exchange Act") requires additional
disclosure relating to the market for penny stocks in connection with trades in
any stock defined as a penny stock. The Commission's regulations generally
define a penny stock to be any equity security that has a market price of less
than $5.00 per share, subject to certain exceptions. Such exceptions include any
equity security listed on the Nasdaq National 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. There can be no
assurance that the Company will meet the requirements of the foregoing financial
exceptions. Failure to qualify under one of these exceptions, will 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 are quoted on
the OTC Bulletin Board (as to which there can be no assurance), then trading in
the Common Stock


                                       15
<PAGE>

would be regulated pursuant to Rules 15-g-1 through 15-g-6 and 15-g-9
promulgated under the Exchange Act for non-National Association of Securities
Dealers Automotive Quotation System and non-exchange listed securities. Under
such rules, broker-dealers who recommend such securities to persons other than
established customers and "accredited investors" must make a special written
suitability determination that the penny stock is a suitable investment for the
purchaser and receive the purchaser's written agreement to this transaction.
Securities are exempt from these rules if the market price of the Common Stock
is at least $5.00 per share. Consequently, such Exchange Act rules may affect
the ability of broker-dealers to make a market in such shares and may affect the
ability of holders of Common Stock to sell in the secondary market.

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

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

The Company is subject to Section 203 of the General Corporation Law of the
State of Delaware which, subject to certain exceptions, prohibits a Delaware
corporation from engaging in any business combination with any interested
stockholder for a period of three years following the date that such stockholder
became an interested stockholder. In general, Section 203 defines an interested
stockholder as any entity or person beneficially owning 15% or more of the
outstanding voting stock of the corporation and any entity or person affiliated
with or controlling or controlled by such entity or person. The foregoing
provisions could have the effect of discouraging others from making tender
offers for the Company's shares and, as a consequence, they also may inhibit
fluctuations in the market price of the Company's shares that could result from
actual or rumored takeover attempts. Such provisions also may have the effect of
preventing changes in the management of the Company.

FORWARD LOOKING STATEMENTS

Certain of the statements set forth in this Prospectus, including, without
limitation, the Company's research and development programs, the anticipated
filing of an IND for AC MelaVax(TM), the seeking of joint development or
licensing arrangements with pharmaceutical companies, the research and
development of particular compounds and technologies for particular indications
and the period of time for which the Company's existing resources will enable
the Company to fund its operations and to meet the initial listing requirements
for the quotation of its securities on the Nasdaq National Market and the
possibility of contracting with other parties additional licenses to develop,
manufacture and market commercially viable products, are forward-looking and
based upon the Company's current belief as to the outcome, occurrence and timing
of future events or current expectations and plans. All such statements involve
significant risks and uncertainties. Many important factors affect the Company's
ability to achieve the stated outcomes and to successfully develop and
commercialize its product candidates, including, among other things, the ability
to obtain substantial additional funds, obtain and maintain all necessary
patents or licenses, to demonstrate the safety and efficacy of product
candidates at each state of development, to meet applicable regulatory standards
and receive required regulatory approvals, to meet obligations and required
milestones under its license agreements, to be capable of producing drug
candidates in commercial quantities at reasonable costs, to compete successfully
against other products and to


                                       16
<PAGE>

market products in a profitable manner. As a result, there also can be no
assurance that these statements included in the Prospectus will prove to be
accurate. In light of the significant uncertainties inherent in these statements
included herein, the inclusion of such information should not be regarded as a
representation by the Company or any other person that the objectives and plans
of the Company will be achieved.

NO DIVIDENDS

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


                                       17
<PAGE>

                                 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 $2,850,000. 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.

                                 DIVIDEND POLICY

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

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

GENERAL

Since its inception, the Company has concentrated its efforts and resources in
the development and commercialization of biotechnology and pharmaceutical
products and technologies. The Company has been unprofitable since its founding
and has incurred a cumulative net loss of approximately $2,222,257 as of June
30, 1996. The Company expects to incur significantly increasing operating losses
over the next several years, primarily due to the expansion of its research and
development programs, including preclinical studies and clinical trials for the
AC MelaVax(TM) product and other products that it may acquire or develop. The
Company's ability to achieve profitability depends upon, among other things, its
ability to discover and develop products, obtain regulatory approval for its
proposed products, and enter into agreements for product development,
manufacturing and commercialization. The Company's AC MelaVax(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 AC MelaVax(TM) or any other products that
it may develop.

The Company's independent auditors included an explanatory paragraph in its
report on the Company's financial statements at December 31, 1995, as to the
uncertainty relating to its ability to continue as a going concern.

PLAN OF OPERATION

The Company is currently engaged in the development and commercialization of
biotechnology and pharmaceutical products and technologies. On November 20,
1995, the Company acquired the rights to the AC Vaccine technology pursuant to
the TJU License. The Company initially intends to focus its efforts primarily on
the development of immunotherapies for cancer pursuant to the TJU License. The
Company anticipates that during the next 12 months that it will conduct
substantial research and development of the AC Vaccine technology, including,
without limitation, Phase II/III or Phase III clinical trials on AC MelaVax(TM),
the Company's lead AC Vaccine for metastic melanoma. See "Business -- Technology
Applications and Product Candidates," "Research and Development." The Company
also anticipates that it will expend resources on the research and development
of additional AC Vaccines. While there can be no assurance, the Company intends
to 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
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.

The Company recently has hired three new employees and anticipates that over the
next 12 months it may hire approximately three more new employees, and may
establish lab facilities for the research and development of the AC Vaccine
technology or any other technologies which 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 CERTAINTY

The Company currently anticipates that its current resources will permit the
Company to meet its business objectives for approximately the next 24-36 months
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, levels of
resources that the Company devotes to the development of manufacturing and
marketing capabilities, technological advances, status of competitors, and
abilities 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 and/or not need to raise additional capital.

                                    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. The Company initially
intends to focus its efforts primarily on the development of immunotherapies for
cancer, which 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 own immune system to
eliminate the cancer. This technology has emerged from research conducted at the
Jefferson Cancer Center of TJU. The technology 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, AC
MelaVax(TM), is currently undergoing a physician-sponsored human clinical trial
based on an experimental protocol at TJU Hospital as an outpatient,
post-surgical, adjunct therapy for the treatment of malignant 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 melanoma. In such
ongoing clinical trial at the Thomas Jefferson Medical Center, 150 malignant
melanoma patients have been treated post-surgically on an outpatient basis with
AC MelaVax(TM). In 62 patients with stage 3 melanoma for whom there has been
sufficient time for long-term follow-up, the four-year survival rate is
approximately 60%. This compares with the historical and control group survival
rate of approximately 20%, and the survival rate for treatment with high dose
alpha interferon of approximately 32%. The Company believes that the results to
date of the ongoing clinical trial represent the first substantial increase in
survival for malignant melanoma patients treated by immunotherapy. In the 150
patients treated in the study, the Company believes that only relatively minor
side effects, such as soreness and swelling at the site of the application of
the AC MelaVax(TM) vaccine, have been witnessed to date.

   
The Company also believes that the AC Vaccine technology possibly may have
applications in the treatment of other cancers such as lung, breast, colon and
prostate cancers. Accordingly, in addition to continuing the clinical work on AC
MelaVax(TM) for melanoma, the Company also has entered into a sponsored research
agreement with TJU relating to the development of additional immunotherapies
based on the AC Vaccine technology. If appropriate, the Company intends to fund
the preclinical and initial clinical development of these technologies. In order
to contain costs, the Company may 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 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.
    

BACKGROUND AND SCIENTIFIC RATIONALE

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 metastasized (spread) to other


                                       22
<PAGE>

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.

In 1994, approximately 1,250,000 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 in
many types of cancers this treatment is effective, in cases in which not all of
the tumor was removed or the tumor has metastasized the patient's prognosis is
poor. Chemotherapy and radiation therapy are rather crude treatments. These
treatments kill cells indiscriminately, destroying normal as well as malignant
cells thus leading to toxic side-effects that limit 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 therefore may 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 which is developed to effectively treat the
recurrence of cancer after surgery is likely to have a sizable market share
since surgery in many cases is the first treatment performed on cancer patients,
and if such a treatment were to be broadly applicable and safe, its market
potential could be significant and the health care system would likely realize
significant 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 immunotherapeutic 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 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


                                       23
<PAGE>

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. 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 then
will 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 lung, breast, colon and prostate
cancers.

    AC MelaVax(TM)

General. The Company's lead product, AC MelaVax(TM), is a post-surgical
treatment for malignant melanoma. Melanoma is a highly malignant tumor that can
spread so rapidly that it can be fatal within months of diagnosis. The incidence
of malignant melanoma is increasing at a faster rate than most other cancers in
the United States, Australia, northern Europe and Canada. Although there are
several causative factors, rising exposure by the general population to UV
radiation in sunlight appears to be the most significant factor behind this
increase. With the incidence growing over 6% annually, melanoma effects over
200,000 people in the United States, with approximately 32,000 new cases
diagnosed in 1994. Surgical excision of the tumor mass remains the generally
accepted treatment to date. 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. Recently the FDA
approved the use of high doses of interferon [alpha] for the post-surgical
treatment of melanoma patients. In clinical studies interferon [alpha] has
demonstrated a five-year survival rate that the Company believes to be
approximately only 30%.

Generally, the first line of treatment for patients with malignant melanoma is
usually the surgical removal of the primary tumor and any of the nearby lymph
nodes into which it has metastasized. Because malignant melanoma usually does
not respond to conventional cancer treatments, these patients generally receive
no chemotherapy or radiation therapy. The five-year survival rate for these
patients is believed by the Company to be approximately 20%. The Company
believes that there is a clear need for an effective post-surgical treatment of
malignant 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's Jefferson
Cancer Center (recently renamed Kimmel Cancer Center). Dr. Berd has been
conducting a physician- sponsored clinical trial for the treatment of malignant
melanoma using AC MelaVax(TM) for approximately the past seven years.

In such ongoing clinical trial at the Thomas Jefferson Medical Center, 150
malignant melanoma patients have been treated post-surgically on an outpatient
basis with AC MelaVax(TM). In 62 patients with stage 3 melanoma for whom there
has been sufficient time for long-term follow-up, the four-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%. The Company believes that the results to date
of the ongoing clinical trial represent the first substantial increase in
survival for malignant melanoma patients, treated by immunotherapy. In the 150
patients treated in the study, the Company believes that only relatively minor
side effects, such as soreness and swelling at the site of the application of
the AC MelaVax(TM) vaccine, have been witnessed to date.

Although TJU and Dr. Berd have conducted the ongoing clinical trial pursuant to
a FDA-approved, physician-sponsored Investigational New Drug Application
("IND"), to date, the Company has not had any direct contact with the FDA
concerning the clinical results obtained with AC MelaVax(TM). However, it is the
Company's intention to use the results of the TJU


                                       24
<PAGE>

clinical trial to support the submission of a Company-sponsored IND to the FDA.
The purpose of the IND submission will be to seek FDA approval to enter AC
MelaVax(TM) into Phase II/III or Phase III multi-center clinical trials.
Although there can be no assurance of such FDA approval, if successful in
obtaining clearance to commence such Company-sponsored IND, 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 AC
MelaVax(TM). The Company also may pursue a similar regulatory approval and
commercialization strategy for AC MelaVax(TM) in Australia and certain countries
in Europe 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.

In connection with the Company's development of its regulatory strategy, the
Company has entered into a consulting agreement with Biometric Research
Institute ("BRI") pursuant to which BRI will advise and assist the Company in
its pursuit of FDA regulatory approvals. The Company's agreement with BRI
terminates on December 31, 1996, subject to extension by mutual consent of the
parties.

RESEARCH AND DEVELOPMENT

In connection with the TJU License, TJU, Dr. Berd, as TJU's principal
investigator, and the Company entered into a Clinical Study and Research
Agreement pursuant to which TJU and Dr. Berd undertook to conduct a research and
clinical study program for the further development of the AC Vaccine technology
for additional cancer targets. In turn, the Company undertook 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. See "Risk Factors--Dependence on License and Sponsored
Research Agreements."

For fiscal years 1994 and 1995, the Company spent approximately $398,622 and
$126,957, respectively, for research and development. See "Financial Statements"

PROPRIETARY RIGHTS

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. The
Company has paid $10,000 to TJU as consideration for the TJU License. In
addition, the Company sold 458,243 shares of Common Stock at a price of $.002
per share to each of TJU and Dr. Berd, representing 7.5% (15% in the aggregate)
of the Company's total outstanding voting securities at the time of issuance.

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


                                       25
<PAGE>

would have a material adverse effect on the Company. See "Risk
Factors--Dependence on License 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 maybe, in direct competition with the
Company's AC Vaccine and its future products and such drugs may perform more
effectively or safely than the Company's product candidates. Many of the
companies engaged in anticancer research and development and in acquiring rights
to the products of such research and development, including biotechnology
companies, have substantially greater financial, technical, scientific,
manufacturing, marketing and other resources than the Company and have more
experience in developing, marketing and manufacturing therapeutics, including
performing the preclinical testing and clinical trials that are required for
obtaining FDA and other regulatory approvals. Included among the Company's
competitors are: (i) large established pharmaceutical companies with commitments
to oncology or antiviral research, development and marketing; (ii) smaller
biotechnology companies with similar strategies; and (iii) many development
stage companies licensing and/or developing oncology therapeutics. In addition,
many research institutes, hospitals and universities are working to develop
products and processes in the same field of cancer that may in the future be in
direct competition with the Company's present and future products.

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

MANUFACTURING AND MARKETING

The Company does not 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.


                                       26
<PAGE>

To date, the Company has not entered into any collaborative commercial
manufacturing or marketing agreements for any of its proposed 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."

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 of an IND, which must become effective before human clinical trials
commence; (iii) adequate and well-controlled human clinical trials to establish
the safety and efficacy of the drug; (iv) the submission of an NDA to the FDA;
and (v) the FDA approval of the NDA prior to any commercial sale or shipment of
the drug. In addition to obtaining FDA approval for each product, each domestic
drug manufacturing establishment must be registered with, and approved by, the
FDA. Domestic manufacturing establishments are subject to biennial inspections
by the FDA and must comply with Good Manufacturing Practices ("GMP") for both
drugs and devices. To supply products for use in the United States, foreign
manufacturing establishments must comply with GMP and are subject to periodic
inspection by the FDA or by corresponding regulatory agencies in such countries
under reciprocal agreements with the FDA. As permitted by FDA regulations, the
AC MelaVax(TM) human clinical trials are being conducted by TJU under the
supervision of Dr. David Berd. If considered successful or sufficiently positive
by the Company, data from such clinical trials may be used to support the filing
of a Company sponsored IND with the FDA to permit the Company to conduct its own
Phase II and/or III clinical trial.

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

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

The Company does not expect to encounter significant difficulties in obtaining
raw materials for AC MelaVax(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 AC MelaVax(TM).

COMPLIANCE WITH ENVIRONMENTAL LAWS

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

EMPLOYEES

   
As of November 6, 1996, the Company has four full-time employees, including
Jeffrey M. Jonas, M.D., its President and Chief Executive Officer, David L.
Tousley, C.P.A., its Chief Financial Officer, and Ernest W. Yankee, Ph.D., its
Executive Vice President. It has seven other employees, consultants, scientific
advisors, part-time officers and directors who devote only a portion of their
time to the business of the Company. The Company believes that it maintains good
relations with Dr. Jonas and its employees, consultants, scientific advisors,
part-time officers and directors. See "Risk Factors--Lack of Management and
Employees" and "--Dependence Upon Key Personnel and Consultants."
    

FACILITIES

The Company's executive offices are located at 4520 Main, Suite 930, Kansas
City, Missouri 64111. The Company anticipates that in the future it may own or
lease its own research facility, although no such lease or ownership interest is
under current consideration. The research and development work of the Company is
currently being conducted on a contract basis at TJU. In addition, the Company
may maintain shared office space in New York subleased from Paramount Capital,
Inc. ("Paramount"), at a cost of approximately $36,000 - $48,000 per annum
depending on the level of services required by the Company. Paramount may be
deemed an affiliate of the Company. See "Risk Factors--Lack of
Facilities,""--Dependence on Third Parties for Additional Funds and for
Manufacturing, Marketing and Selling," and "--Dependence on Others for Clinical
Development of, Regulatory Approvals for, and 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.

scientific and product development opportunities, in reviewing and evaluating
scientists and other employees. Presently, the Scientific Advisory Board members
consists of:


David Berd, M.D. -- Chairman        Clinical Oncologist at the Jefferson Cancer
                                    Center of TJU and Inventor of the Company's

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 future scientific advisors will be

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 affiliate 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.

                              CERTAIN TRANSACTIONS

   
Pursuant to a private offering held in May and June 1996, the Company
consummated an offering of Series B Preferred Stock (the "Series B Offering")
pursuant to which the Company raised aggregate gross proceeds of approximately
$25,900,000. In connection with services rendered by Paramount Capital, Inc., as

Offering, and pursuant to a placement agency agreement entered into by the
Company and the Placement Agent, the Company paid the Placement Agent cash
commissions of approximately $2,330,000, a non-accountable expense allowance of

shares of Series B Preferred Stock, exercisable until June 15, 2006 at an

On December 27, 1995, the Company sold its former leading product under

Product, Interneuron agreed to pay in two installments, in December 1996 and

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

payable to those persons who were recorded holders of shares of the Company's
Series A Preferred Stock on December 27, 1995. 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 October 30, 1996 was $12.50
and $24.375 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

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,

                                       35

as placement agent, pursuant to a placement agency agreement, for a bridge
financing for the Company as to which Paramount was paid $90,000 in commissions
and received warrants to purchase 62,500 shares of Common Stock. Two of the

                            DESCRIPTION OF SECURITIES

   
The Company is authorized to issue up to 50,000,000 shares of Common Stock, par
value $.002 per share, and 5,000,000 shares of preferred stock, par value, $.01
per share, of the Company. As of September 30, 1996, 6,222,316 shares of Common
Stock and 259,198 shares of Series B Preferred Stock were issued and
outstanding.
    

COMMON STOCK

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

PREFERRED STOCK

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

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

SERIES A PREFERRED STOCK

At one time, the Company had designated and issued 1,287,500 shares of Series A
Preferred Stock, par value $.01 per share ("Series A Preferred Stock"). Pursuant
to an automatic conversion provision in the Certificate of Designations
therefor, all outstanding shares of Series A Preferred Stock were converted into
an aggregate of 643,750 shares of Common Stock effective as of June 11, 1996, in
connection with the second closing of the Series B Offering. 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. See "Certain Transactions."

                                       39

<PAGE>

SERIES B PREFERRED STOCK

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

      Dividends

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

      Conversion

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

      Mandatory Conversion

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

      Liquidation

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

                                       40

<PAGE>

      Voting Rights

The holders of the Series B Preferred Stock have the right at all meetings of
stockholders to the number of votes equal to the number of shares of Common
Stock issuable upon conversion of the Series B Preferred Stock at the record
date for determination of the stockholders entitled to vote. So long as 50% of
the shares of Series B Preferred Stock remain outstanding, the holders of 66.67%
of the Series B Preferred Stock are entitled to approve (i) the issuance of any
securities of the Company senior to or on parity with the Series B Preferred
Stock, (ii) any alteration or change in the rights or 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") have 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, any Conversion Shares, without the prior written consent of the
placement agent in the Series B Offering. Such restrictions apply until (i)
December 11, 1996 with respect to 50% of each of the holders' Conversion Shares,
(ii) March 11, 1997 with respect to the remaining 25% of each of the holders'
Conversion Shares.

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

1992 STOCK OPTION PLAN

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

The AVAX Option Plan provides for the grant of "incentive stock options" within
the meaning of Section 422 of the Internal Revenue Code of 1986, as amended, and
nonqualified stock options to employees, directors and consultants of the
Company. Incentive stock options may be granted only to employees. The AVAX
Option Plan is administered by the Board of Directors of the Company (or a
Committee thereof) which determines the terms of the options granted, including
the exercise price, the number of shares subject to the option, and the schedule
on which the option becomes exercisable.

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

                                       41

<PAGE>

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 November 6, 1996, options to purchase
60,000 shares of Common Stock were outstanding (of which 48,889 were vested) at
a weighted average price of $0.60 per share, and no options had been exercised.
    

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

OTHER OPTIONS

Pursuant to their letters of employment with the Company, Dr. Jonas, Mr.
Tousley, and Dr. Yankee and another employee of the Company received share
options to acquire 637,745, 250,000, 200,000 and 5,000 shares, respectively, of
Common Stock at an exercise price of $.50 per share. All such share options will
vest at a rate of 1/16 per quarter over a four-year period and are exercisable
for a period of seven years.

stock at below market price) by adjustment of the applicable exercise price
and/or the number of shares issuable upon exercise of such warrants.
    

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

holder of Common Stock unless and until the applicable warrant is exercised.

REGISTRATION RIGHTS

Common Stock owned by TJU, Dr. Berd, VentureTek, L.P. and, Dr. Rosenwald. Under
terms of the agreements between the Company and the holders of such registrable

securityholders exercising registration rights, such holders are entitled to
notice of such registration and are entitled to include such shares of Common
Stock therein. Holders of the Castelli and Shear/Kershman Warrants are entitled

circumstances. The holders of the Meyerson Warrants and holders of any shares of
Common Stock issued upon exercise of the Meyerson Warrants ("Meyerson Shares")

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

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

(3)   See also footnote 5 to the table set forth under "Principal Stockholders."

       

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

                        SHARES ELIGIBLE FOR FUTURE SALES

   
Upon completion of the Offering, the Company will have 21,296,932 shares of
Common Stock outstanding or issuable upon the conversion of the Series B
Preferred Stock, the exercise of all outstanding options and warrants as of
September 30, 1996. Of these shares, the 14,885,088 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 987,776
shares of Common Stock may be eligible for sale without restriction or further
registration under the Securities Act, subject to certain requirements. See
"Risk Factors--Potential Adverse Effect of Shares Eligible For Future Sales."
The Company has a Stock Option Plan under which 875,000 shares of Common Stock
have been reserved for issuance, and has also reserved 1,092,745 shares of
Common Stock for issuance pursuant to the employment arrangements among the
Company and Dr. Jonas, Mr. Tousley, Dr. Yankee and one other non-executive
employee.
    

SALES OF RESTRICTED SHARES

The Company believes that 4,386,409 shares of Common Stock are "restricted
securities" and under certain circumstances may, in the future, be sold in
compliance with Rule 144 (including 987,776 shares owned by persons whom the
Company believes may be affiliates of the Company, but as to which there can be
no assurance, and whose shares therefore may not be restricted). Assuming the
availability of Rule 144, the Company believes that of the 4,386,409
"restricted" shares of Common Stock, 987,776 shares of Common Stock is eligible
for sale and an additional 3,398,632 shares of Common Stock will be eligible for
sale in 1997 pursuant to Rule 144, in each case 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, subject to the satisfaction of certain other
conditions, a person, including an affiliate of the Company, who beneficially
owned restricted shares of Common Stock for at least two years is entitled to
sell, within any three-month period, a number of shares that does not exceed the
greater of one percent of the total number of outstanding shares of the same
class, or if the Common Stock is quoted on the Nasdaq National Market or a
national securities exchange, the average weekly trading volume during the four
calendar weeks immediately preceding the sale. A person who presently is not and
who has not been an affiliate of the Company for at least three months
immediately preceding the sale and who has beneficially owned the shares of
Common Stock for at least three years is entitled to sell such shares under Rule
144 without regard to the volume limitations described above.

Prior to the Offering, there has been no public market for the Common Stock and
no predictions can be made of the effect, if any, that the sale or availability
for sale of Restricted Shares of locked-up shares will have on the market price
of the Common Stock. 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 14,885,088 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 Common Stock may be
subject to a lock-up agreement. See "Description of Securities -- LockUp
Agreements"). In connection with such sales, the Selling Securityholders and any
participating broker may be deemed to be "underwriters" of the shares of Common
Stock within the meaning of the Securities Act, although the offering of these
securities will not be underwritten by a broker-dealer firm. Sales in the market
may be made to broker-dealers making a market in the Common Stock or other
broker-dealers, and such broker-dealer, upon their resale of such securities,
may be deemed to be "Selling Securityholders" in this offering. The Company will
not receive any of the proceeds from the sale of the Common Stock by the Selling
Securityholders. Pursuant to the terms under which the Preferred Stock and
Placement Warrants were issued and sold, the Company has agreed to indemnify the
Selling Securityholders against such liabilities as they may incur as a result
of any untrue statement of a material fact in the Registration Statement of
which this Prospectus forms a part, or any omission herein or therein to state a
material fact necessary in order to make the statements made, in the light of
the circumstances under which they were made, not misleading. Such
indemnification includes liabilities that the Selling Securityholders may incur
under the Securities Act.

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

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

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

The Company will inform the Selling Securityholders that the anti-manipulation
provisions of Rules 10b-6 and 10b-7 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.

                         Report of Independent Auditors

The Board of Directors and Stockholders
AVAX Technologies, Inc. 
(formerly Walden Laboratories, Inc.)

   
We have audited the accompanying balance sheets of AVAX Technologies, Inc.
(formerly Walden Laboratories, Inc.) (a development stage company) as of
December 31,1995, and the related statements of operations, stockholders' equity
(deficit), and cash flows for the years ended December 31, 1995 and 1994 and for
the period from January 12, 1990 (incorporation) to December 31, 1995 (not
presented herein). 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.

Since the date of completion of our audit of the accompanying financial
statements and initial issuance of our report thereon dated March 20, 1996,
which report contained an explanatory paragraph regarding the Company's ability
to continue as a going concern, the Company, as discussed in Note 9, has
completed an issuance of its Series B preferred stock resulting in net proceeds
of approximately $22,347,000. Therefore, the conditions that raised substantial
doubt about whether the Company will continue as a going concern no longer
exist.

   
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, 1995, and the results of
its operations and its cash flows for the years ended December 31, 1995 and 1994
and for the period from January 12, 1990 (incorporation) to December 31, 1995 in
conformity with generally accepted accounting principles.

1. Description of Business and Significant Accounting Policies

Description of Business

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

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

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

Interim Financial Statements

The interim financial statements at June 30, 1996 and for the six months ended
June 30, 1995 and 1996 and for the period from January 12, 1990 (incorporation)
to June 30, 1996 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.

Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles require 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 June 30, 1996,
substantially all cash and cash equivalents were held in one financial
institution.

Depreciation

Depreciation is computed using the straight-line method over the estimated
useful lives of the assets which range from 3 to 5 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.
Organizations costs are amortized over sixty months.

       the period from January 12, 1990 (incorporation) to June 30, 1996)

   Policies (continued)

Share Information

Prior to the first closing of a private placement on May 15, 1996 (see Note 9),
the Company effected a 1-for-2 reverse stock split of the Company's common
stock. All outstanding share amounts included in the accompanying financial
statements have been adjusted to reflect the 1-for-2 reverse stock split
disclosed in Note 9.

Net Income (Loss) Per Share

Net income (loss) per share is based upon 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 9) has been
considered to be the equivalent of an initial public offering and the initial
public offering price was determined to be $1.96 per share by assuming that the
preferred stock issued was immediately converted into common stock. All options
and warrants issued prior to one year from the private placement were
antidilutive or immaterial and, accordingly, excluded from the calculation of
weighted average shares. Series A convertible preferred stock was included in
the calculation of the weighted average number of shares for the year ended
December 31, 1995. Such stock was antidilutive for all other periods.

   
Supplementary net income (loss) per share include the conversion of Series A
preferred stock and the estimated number of shares assumed to be sold by the
Company (641,327 at $1.96 per share) to repay certain debt of $1,257,000.  Net
income (loss) per share would have been $.10 for the year ended 
December 31, 1995 and $(.02) and $(.22) for the six months ended June 30, 1995
and 1996, respectively, if the said shares had been converted/issued at the 
beginning of the respective periods.

1. Description of Business, Basis of Presentation and Significant Accounting
   Policies (continued)

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 intends to continue to account for its stock based
compensation plans in accordance with the provisions of APB 25.

2. Sale of the Product

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, respectively, is fixed and the number of shares of Stock will vary 
depending on the quoted market price of the Stock at such time.

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

                          (a development stage company)

                    Notes to Financial Statements (continued)

 (Unaudited with respect to the six months ended June 30, 1995 and 1996 and for
       the period from January 12, 1990 (incorporation) to June 30, 1996)


2.  Sale of the Product (Continued)

- - At approximately the same time each installment is received by the Company,
  95.85% of the Stock will be distributed by the Company to its preferred
  stockholders of record at the time the 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) 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.

- - The remaining 4.15% of the Stock (or a cash payment equal to the value
  thereof) will be distributed to the Company's former President and Chief
  Executive Officer (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 250,000 shares of
  common stock that was ever owned by him (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%. 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 total amount payable to the preferred stockholders could be
$2,300,400 if all of the Company's indebtedness outstanding as of the date of
the sale of the Product is satisfied through sources other than the Stock to be
received. However, to the extent such amount of indebtedness remains outstanding
as of the date of receipt of the Stock and, the repayment of such indebtedness
is not otherwise provided for, the amount paid to the preferred stockholders
will be satisfied from the proceeds of the Stock receivable (see Note 9).

2. Sale of the Product (Continued)

The discounted net present value of the Stock distributable to the Former
Officer, $80,967, was allocated between common stock ($445) and severance
expense ($80,522) based on the fair value of the Company's common stock ($.002
per share).

3. License and Research Agreements

In November 1995, the Company entered into an agreement with the University for
the exclusive worldwide license to develop, manufacture and sell the Invention.
The Company paid cash of $10,000 as consideration for the license agreement. In
addition, the Company sold an aggregate of 916,486 shares of common stock at
$.002 per share (the fair value of the Company's common stock) to the 
University and the scientific founder (the "Scientist"). These shares have 
anti-dilution 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 and a percentage of all revenues received from sublicensees.

3. License and Research Agreements (Continued)

The Company also entered into a research agreement with the University to fund a
study to be performed by the University 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.

4. Equity Transactions

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 
purposess are as follows:

7. Commitments

Leases

The Company leased office facilities on a month-to-month basis through April 
1995. Rent expense amounted to approximately $34,000 and $10,000 for the years 
ended December 31, 1994 and 1995, respectively ($10,000 for the six months 
ended June 30, 1995).

Employment and Consulting Agreements

In May 1996, the Company entered into a letter agreement with its President and
Chief Executive Officer (the "President") pursuant to which the President will
receive an annual salary of $200,000 and a minimum annual bonus of $25,000 and
an additional discretionary bonus of up to $175,000. In addition, the President
received options to purchase 637,745 shares of common stock at $.50 per share.
Such options vest at a rate of 1/16 per quarter over four years and are
exercisable for a period of seven years. Because the fair value of the Company's
common stock at the date of grant was determined to be $1 per share, the Company
recorded $318,873 as deferred compensation. Such deferred compensation is being
amortized over four years.

Employment and Consulting Agreements (Continued)

Effective in June 1996, the Company entered into consulting agreements with the
Scientist, a Director and a former officer. These agreements are for an initial
term of three years through June 1999. Annual consulting fees payable pursuant
to these agreements approximate $126,000.

   
In September 1996, the Company entered into letter agreements with its Chief
Financial Officer (the "CFO") and Executive Vice President (the "Executive
V.P.") pursuant to which these officers will receive annual salaries of $150,000
and $145,000, respectively, minimum annual bonuses of $25,000 each and
additional discretionary bonuses of up to $125,000 and $83,750, respectively. In

In October 1996, the Company entered into an agreement with an investment banker
pursuant to which the investment bankers may, at the Company's request, perform
certain investment banking and financial advisory services for the Company. In
connection with this agreement, the investment bankers were granted warrants to
purchase 100,000 shares of common stock at $3 per share.
    

8. Loans Payable and Related Party Transactions

On March 1, 1994, the Company entered into a line of credit agreement with a
major stockholder. During 1994, the Company received $397,000 and repaid
$190,000. There were no borrowings or repayments during 1995. Borrowings under
this line of credit amounted to $207,000 at December 31, 1995 and bore interest
at 2% above the prime rate. Borrowings under this line of credit were repaid in
full in June 1996 (10.5% at December 31, 1995).

On November 16, 1994, the Company entered into a term loan with a financial
institution and borrowed $389,000. The outstanding balance at December 31, 1995
was $50,000. The above major stockholder had assigned certain bank deposits as

rate (8.5% at December 31, 1995) was repaid in June 1996.

8. Loans Payable and Related Party Transactions (Continued)

In 1995, the Company obtained four separate bridge loans totaling $600,000
($150,000 from related parties). The lenders  also were granted warrants to
purchase 150,000 shares of common stock at $.02 per share. In connection with
these loans, the Company paid financing costs totaling $54,000 and, issued
warrants to purchase 30,000 shares of common stock at $.02 per share, to the
placement agent (the "Placement Agent"), a related party. The warrants were
considered to have a de minimus value. These loans bore interest at 13% per
annum and are payable in 12 months. Loans totaling $200,000 were paid in January
and February 1996 and loans totaling $250,000 that were due in February 1996
were rolled over for another year through February 1997. However, all bridge
loans were payable in full upon the closing of an initial public offering or
private placement of the Company's stock, with gross proceeds in excess of
$2,500,000. In addition, in January and February 1996, the Company obtained
additional bridge loans totaling $400,000 ($300,000 from related parties) with
interest payable at 13% per annum and, issued additional warrants to purchase
195,000 (32,500 to the Placement Agent) shares of common stock at $.02 per share
in connection with the new bridge loans and the rollover of bridge loans. All
bridge loans were repaid in June 1996.

In April 1995, in connection with his resignation, the Former Officer also
received $75,000 (payable over a twelve-month period) and reimbursement of
certain expenses. In May 1995, the Company entered into an agreement with an
officer, director and principal stockholder of the Company upon her resignation
from the Company. Under the terms of the agreement, the Company agreed to
release and relinquish any claim the Company may have on intellectual property
created by the former director prior to or during her term of employment with
the Company, other than for the Product and, the former director returned all
shares of common stock of the Company owned by her and her family.

On June 11, 1996, the Company entered into a financial advisory agreement with
the Placement Agent, pursuant to which the Company will pay a monthly retainer
of $4,000 for a minimum of twenty four-months, plus expenses and success fees.

9. Private Placement

Pursuant to the private placement in May and June 1996, the Company issued
258,198 shares of Series B convertible preferred stock. The preferred
stockholders also received 258,198 shares of common stock. The total
consideration was $25,819,800. The per share price allocated to common stock
and Series B Preffered Stock was $1 and $99, respectively. The series B
preferred stock is convertible into 12,959,900 shares of common stock. In
connection with the private placement, the Company paid $3,357,000 as commission
and non-accountable expenses to the placement agent, a related party and, issued
1,000 shares of common stock and 1,000 shares of Series B convertible preferred
stock as consideration for legal services valued at $100,000. In addition, the
placement agent received warrants to purchase 25,819.8 shares of convertible
Series B preferred stock at an exercise price of $110 per share. Such warrants
are exercisable until June 15, 2006. Other share issuance expenses amounted to
$115,397.

At the second closing of the private placement on June 11, 1996, the 643,750
shares of Series A preferred stock were automatically converted to 643,750
shares of common stock. Notwithstanding such conversion, holders of the Series A
preferred stock will receive pro-rata, 95.85% of shares of common stock of IPI
valued at $2,400,000 receivable by the Company (See Note 2). Because the Company
will be able to pay its indebtedness from the proceeds of the private placement,
the amount payable to the Series A preferred stockholders was increased to
$2,014,743 (95.85% of the discounted net present value of the Stock receivable)
at June 30, 1996.

                     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. Reference is made to Section 5.7 of the
Subscription Agreements of the Series B Offering (Exhibit 4.6), Section 5(a) of
the Series B Placement Warrants (Exhibit 4.12), Section 6(e) of the Bridge
Placement Warrants (Exhibit 4.7) and Section 11 of the Meyerson Warrants
(Exhibit 4.13) indemnifying against certain liabilities of certain of the
Company's stockholders or 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 15, 1996 (the "Closing Dates"), the Company
          consummated a private placement of an aggregate of approximately
          $25,900,000 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.

   
     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)
    

                                      II-2

<PAGE>

          thereof and Regulation D promulgated thereunder. The recipients of
          securities in each such transaction represented their intentions to
          acquire the securities for investment only and not with a view to or
          for sale in connection with any distribution thereof and appropriate
          legends were affixed to the certificates issued in such transactions.

   
     3.   On November 20, 1995, the Company entered into a License Agreement
          (the "TJU License Agreement') with Thomas Jefferson University ("TJU")
          pursuant to which TJU licensed to the Company certain patent and
          patent applications relating to a process for the modification of a
          patient's own tumor cells into a cancer vaccine (the "TJU License").
          Pursuant to the TJU License Agreement, the Company issued 458,243
          shares of Common Stock at a price of $.002 per share to each of TJU
          and Dr. David Berd, TJU's chief oncologist and the inventor of its
          cancer vaccine. In the stock subscription agreements ("Subscription
          Agreements") entered into by the Company, TJU and Dr. Berd on November
          20, 1995, relating to the issuance of Common Stock to each of TJU and
          Dr. Berd, each of TJU and Dr. Berd represented, among other things, to
          the Company the following: that (i) it acquired the Common Stock for
          investment purposes only and not for resale for an indefinite period
          of time for its own account; (ii) it had such 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 the opportunity prior to its purchase of the Common Stock
          to ask questions of and receive answers from representatives of the
          Company 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 916,486
          of Common Stock of the Company at a price of $.002 per share pursuant
          to an Engagement & Technology Acquisition Agreement dated October 20,
          1995 between The Castle Group and the Company. In the stock
          subscription agreements ("Castle Subscription Agreements") entered
          into by the Company, The Castle Group and its designees in September,
          1995, relating to the Common Shares issued to each of The Castle Group
          and its designees, each of them represented, among other things, to
          the Company the following: that (i) it acquired the Common Stock for
          investment purposes only and not for resale for an indefinite period
          of time for its own account; (ii) that each of The Castle Group and
          its designees had such 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 the
          opportunity prior to its purchase of the Common Stock to ask questions
          of and receive answers from representatives of the Company concerning
          the finances, operations and business of the Company. Also, as stated
          in the Subscription Agreements, the share certificates issued in
          connection with the above issuance of Common Stock had endorsed
          thereon legends regarding restrictions on the transfer of the Common
          Stock. Because of the foregoing, the issuances of the above referenced
          securities was deemed to be exempt from registration under the
          Securities Act in reliance on Section 4(2) thereof because such
          issuances were transactions not involving a public offering. In
          addition, each of the recipients of securities in such transaction
          represented their intention to acquire the securities for investment
          only and not with a view

          to or for sale in connection with any distribution thereof and conform
          to appropriate legends were affixed to the share certificates issued
          in such transactions. All recipients had adequate access, through
          their relationships with the Company, to information about the
          Company.

   
     5.   In 1995 and 1996, the Company pursuant to certain bridge financing
          transactions issued to nine persons or entities ("Warrant Holders")
          (i) bridge notes aggregating $1,000,000 and (ii) warrants to purchase
          an aggregate of 312,500 shares of Common Stock at an exercise price of
          $.002 per share. In June 1996, such bridge notes were paid by the
          Company and all the warrants were exercised by the holders thereof. In
          connection with services rendered as the placement agent of the bridge
          financing, Paramount Capital, Inc. was issued warrants to purchase
          62,500 shares of Common Stock at an exercise price of $.002 per share.
          In connection with the issuances of the Warrants and the Placement
          Warrants, it represented, among other things, the following: that (i)
          it acquired the Common Stock for investment only and not for resale
          for an indefinite period for its own account; (ii) it had such
          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 the opportunity prior
          to its purchase of the Common Stock to ask questions of and receive
          answers from representatives of the Company concerning the finances,
          operations and business of the Company. Also, as stated in the
          Subscription Agreements, the share certificates issued in connection
          with the above issuance of Common Stock had endorsed thereon legends
          regarding restrictions on the transfer of the Common Stock. The
          issuances of the above referenced securities was deemed to be exempt
          from registration under the Securities Act in reliance on Section 4(2)
          thereof because such issuances were transactions not involving a
          public offering.

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

Item 28.  Undertakings

     The Company hereby undertakes that it will:

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

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

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

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

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

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

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the Company
pursuant to the Delaware General Corporation Law, the Certificate of
Incorporation or the By-Laws of the Company, or otherwise, the Company has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act, and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Company of expenses
incurred or paid by a director, officer, or controlling person of the Company in
the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered hereunder, the Company will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question of whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed by
the final adjudication of such issue.

     The Company hereby undertakes that it will:

     (1) For determining any liability under the Securities Act, treat the
information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the Company pursuant to Rule 424(b)(1), or (4) or 497(h)
under the Securities Act as part of this registration statement as of the time
it was declared effective.

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

Dr. Jeffrey Jonas
AVAX Technologies, Inc.

Kansas City, MO 64112

Dear Dr. Jonas:

     THIS AGREEMENT (the "AGREEMENT") is made as of October 24, 1996 between
AVAX Technologies, Inc. ("AVAX") and M.H. Meyerson & Co., Inc. ("MEYERSON").

     In consideration of the mutual covenants contained herein and intending to
be legally bound thereby, AVAX and MEYERSON hereby agree as follows:

     1. MEYERSON will perform investment banking services for AVAX on the terms
     set forth below for a period of five years from the date hereof. Such
     services will be performed on a best efforts basis, only as requested, and
     will include, without limitation, assistance to AVAX in mergers,
     acquisitions, and internal capital structuring and the placement of new
     debt and equity issues of AVAX, all with the objective of accomplishing
     AVAX's business and financial goals. In each instance, MEYERSON shall
     endeavor, subject to market conditions, to assist AVAX in identifying
     corporate candidates for mergers and acquisitions and sources of private
     and institutional funds; to provide planning, structuring, strategic and
     other advisory
<PAGE>

                                                                               2

     services to AVAX; and to assist in negotiations on behalf of AVAX. In each
     instance, MEYERSON will render such services as to which AVAX and MEYERSON
     mutually agree and MEYERSON will exert its best efforts to accomplish the
     goals agreed to by MEYERSON and AVAX. No provision in this AGREEMENT shall
     be construed as to require AVAX to pay any fee or other compensation (other
     than as set forth in paragraphs 3 and 10) to MEYERSON on account of the
     services to be provided by MEYERSON as set forth in this paragraph 1 or as
     otherwise contemplated by this AGREEMENT unless such fee or compensation is
     set forth in a separate written agreement between AVAX and MEYERSON as
     contemplated by paragraph 10. In addition, nothing contained herein shall
     require AVAX to request or utilize the services of MEYERSON as set forth
     herein and AVAX may without restriction retain others to perform the same
     or similar services without incurring any obligation (financial or
     otherwise) to MEYERSON.

     2. In connection with the performance of this AGREEMENT, MEYERSON and AVAX
     shall comply with all applicable laws and regulations, including, without
     limitation, those of the National Association of Securities Dealers, Inc.
     and the Securities and Exchange Commission.

     3. In consideration of the services previously rendered and to be rendered
     by MEYERSON hereunder, MEYERSON is hereby granted Warrants to purchase, at
     a price of $3.00 per Share, a total of 100,000 Shares of Common Stock of
     AVAX, with demand and piggyback registration rights as set forth in
     paragraph 5 below. Such Warrants ("MEYERSON Warrants") may be exercised at
     any time from October 24, 1996 to and including October 24, 2001. The
     MEYERSON Warrants shall vest and become irrevocable as follows: 50,000
     Warrants 60 days after the date of this AGREEMENT; 25,000 Warrants 180 days
     after the date of this AGREEMENT, and an additional 25,000 Warrants 365
     days after the date of this AGREEMENT. The shares issuable upon exercise of
     the Warrants may contain a legend satisfactory to AVAX and its counsel.
     MEYERSON understands that the MEYERSON Securities have not been registered
     under the Securities Act of 1933 (the Act") by reason of a claimed
     exemption under the provisions of the act which depends, in part, upon the
     MEYERSON investment intention. In this connection, MEYERSON hereby
     represents that (a) MEYERSON is acquiring the MEYERSON Securities for
     MEYERSON's own account for investment and not with a view toward the resale
     or distribution to others and (b) MEYERSON was not formed for the purpose
     of acquiring the MEYERSON Securities. MEYERSON understands that Rule 144
     promulgated under the Act requires, among other conditions, a two year
     holding period prior to the resale (in limited amounts) of securities
     acquired in a non-public offering without having to satisfy the
     registration requirements under the Act.

                                                                               3


     4. If AVAX should, at any time, or from time to time hereafter, effect a
     stock split, a reverse stock split, or a recapitalization, the terms of the
     MEYERSON Warrants shall be proportionately adjusted to prevent the dilution
     or enlargement of the rights of the holders.

     5. During the period from October 24, 1998 to October 24, 2001, the holders
     of at least 51% of: (i) the MEYERSON Warrants not then exercised; and (ii)
     the shares previously issued upon exercise of any of the MEYERSON Warrants
     (hereinafter, collectively, the "MEYERSON EQUITY") may demand, on one
     occasion only, AVAX at AVAX's expense, promptly, and in any event within 30
     days or such longer period of time as the parties shall agree, file a
     Registration Statement under the Act to permit a public resale of the
     shares of Common Stock issued and issuable pursuant to exercise of the
     MEYERSON Warrants (the "MEYERSON SHARES"). Additionally, if AVAX, during
     the period from October 24, 1998 to October 24, 2001, files a Registration
     Statement covering the sale of any of AVAX's common stock, then AVAX, on
     each such occasion, at the request of the holders of at least 51% of the
     shares and warrants constituting the MEYERSON EQUITY, shall include in any
     such Registration Statement, at AVAX's expense, the MEYERSON SHARES,
     provided that, if the sale of securities by AVAX is being made through an
     underwriter and the underwriter objects to inclusion of the MEYERSON SHARES
     in the Registration Statement, the MEYERSON SHARES shall not be so included
     in the Registration Statement or in any registration statement filed within
     90 days after the effective date of the underwritten Registration
     Statement.

     6. The obligation of AVAX to register the MEYERSON SHARES, including the
     shares issuable upon exercise of the MEYERSON Warrants, pursuant to the
     demand or the piggyback registration rights set forth in paragraph 5,
     above, shall be without regard to whether the MEYERSON Warrants have been
     or will be exercised.

     7. AVAX agrees that, for a period of three (3) years from the date of this
     AGREEMENT, AVAX will not utilize the registration exemption set forth in
     Regulation S under the ACT, nor register any security under form S-8
     (except for securities held by or issued to officers, directors or
     employees of AVAX) without the consent of MEYERSON, which consent will not
     be unreasonably withheld.

     8. This AGREEMENT constitutes the entire Warrant Agreement between the
     parties and when a copy hereof is presented to AVAX's transfer agent,
     together with a certified check in the proper amount and a request that all
     or part of the MEYERSON Warrant be exercised, the certificates for the
     appropriate number of shares of Common Stock shall be promptly issued.

     9. Upon the execution of this AGREEMENT, AVAX shall include in their next
     annual report a copy of this investment banking AGREEMENT as an exhibit
     thereto.

     10. Upon the signing of this AGREEMENT, AVAX shall pay MEYERSON $15,000.00
     as a non-accountable and non-refundable expense allowance for due diligence
     and general compliance review. MEYERSON shall be entitled to additional
     normal and ordinary compensation, to be negotiated and set forth in a
     separate written agreement between MEYERSON and AVAX, arising out of any
     transactions that are proposed or executed by MEYERSON and consummated by
     AVAX, or are executed by MEYERSON at AVAX's request, during the term of
     this AGREEMENT. In addition, MEYERSON shall be reimbursed by AVAX for any
     reasonable out-of-pocket expenses that MEYERSON may incur in connection
     with rendering any service to or on behalf of AVAX that is approved, in
     writing, in advance by AVAX's Chief Executive Officer.

     11. AVAX agrees to indemnify and hold MEYERSON and its directors, officers
     and employees harmless from and against any and all losses, claims,
     damages, liabilities, costs or expenses arising out of any action or cause
     of action brought against MEYERSON in connection with its rendering
     services under this AGREEMENT except for any losses, claims, damages,
     liabilities, costs or expenses resulting from any violation by MEYERSON of
     applicable laws and regulations including, without limitation, those of the
     National Association of Securities Dealers, Inc. and the Securities and
     Exchange Commission or any state securities commission or from any act of
     MEYERSON involving gross negligence or willful misconduct and except that
     AVAX shall not be liable for any amount paid in settlement of any claim
     that is settled without its prior written consent.

     12. MEYERSON agrees to indemnify and hold AVAX and its directors, officers
     and employees harmless from and against any and all losses, claims,
     damages, liabilities, costs or expenses resulting from any violation by
     MEYERSON of applicable laws and regulations including, without limitation,
     those of the National Association of Securities Dealers, Inc., the
     Securities and Exchange Commission, any state securities commission or from
     any act of MEYERSON involving gross negligence or willful misconduct.

     13. Within 30 days of the date of this AGREEMENT, a representative of
     MEYERSON will visit the scientific facilities of AVAX located at Thomas
     Jefferson University, Walnut Street, Philadelphia, Pennsylvania. In
     connection therewith, MEYERSON will execute a confidentiality agreement
     satisfactory in form and substance to AVAX and its counsel.

     14. Nothing contained in this AGREEMENT shall be construed to constitute
     MEYERSON as a partner, employee, or agent of AVAX; nor shall either party
     have any authority to bind the other in any respect, it being intended that
     MEYERSON is, and shall remain an independent contractor.

     15. This AGREEMENT may not be assigned by either party hereto, shall be
     interpreted in accordance with the laws of the State of New York, and shall
     be binding upon the successors of the parties. Either party may terminate
     this investment banking contract at any time, however, Warrants legally
     vested in accordance with paragraph 3 will remain with MEYERSON. All
     unvested Warrants will be cancelled.

     16. If any paragraph, sentence, clause or phrase of this AGREEMENT is for
     any reason declared to be illegal, invalid, unconstitutional, void or
     unenforceable, all other paragraphs, sentences, clauses or phrases hereof
     not so held shall be and remain in full force and effect.

     17. None of the terms of this AGREEMENT shall be deemed to be waived or
     modified except by an express agreement in writing signed by the party
     against whom enforcement of such waiver or modification is sought. The
     failure of either party at any time to require performance by the other
     party of any provision hereof shall, in no way, affect the full right to
     require such performance at any time thereafter. Nor shall the waiver by
     either party of a breach of any provision hereof be taken or held to be a
     waiver of any succeeding breach of such provision or as a waiver of the
     provision itself.

     18. Any dispute, claim or controversy arising out of or relating to this
     AGREEMENT, or the breach thereof, shall be settled by arbitration in New
     York City, New York, in accordance with the Commercial Arbitration Rules of
     the American Arbitration Association. The parties hereto agree that they
     will abide by and perform any award rendered by the arbitrator(s) and that

     having jurisdiction over the party against whom the judgment is being

                            Registration on Form SB-2

Dear Sirs:

     We have acted as counsel for AVAX Technologies, Inc., a Delaware
corporation (the "Issuer"), in connection with the preparation of the
registration statement on Form SB-2 (the "Registration Statement") filed with
the Securities and Exchange Commission (the "Commission") on September 20, 1996,
Registration Number 33- 09349, as amended by Amendment No. 1 thereto filed with
the Commission on September 23, 1996, as further amended by Amendment No. 2
thereto filed with the Commission on November 6, 1996, under the Securities Act
of 1933 (the "Act") for the registration under the Act of the following
securities of the Issuer:

     (i) 571,698 shares of common stock, par value $.002 per share ("Common
     Stock");

     (ii) 12,959,900 shares of Common Stock issuable upon conversion of
     currently outstanding shares of Series B Convertible Preferred Stock, par
     value of $.01 per share (the "Series B Preferred Stock"); and

     (iii) up to 1,353,490 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 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").


<PAGE>

                                                                               2



     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

(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 571,698 shares of Common Stock which may be issued and sold in
accordance with the provisions of the Registration Statement will be, when
issued and sold, legally issued, fully paid and nonassessable.

     3. The 12,959,900 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
Preferred Stock will be legally issued, fully paid and nonassessable.

     4. The aggregate of up to 1,290,990 shares of Common Stock issuable upon
conversion of the Series B Preferred Stock after exercise of the Series B
Placement Warrants have been duly authorized for issuance, and when issued upon

Placement Warrants, and the payment of the applicable exercise price thereof or
the use of the cashless exercise provision thereof will be legally issued, fully
paid and nonassessable.

exercise provision thereof will be legally issued, fully paid and
non-assessable.

with respect to, any laws other than the laws of the State of New York, the
