                                  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) 1,209,234 shares of the Company's
common stock, par value $.004 per share (the "Common Stock"); (ii) 5,096,785
shares of Common Stock issuable upon conversion of currently outstanding shares
of Series B Convertible Preferred Stock, par value $.01 per share, of the
Company ("Series B Preferred Stock"); and (iii) 49,229 shares of Common Stock
issuable upon (a) the conversion of shares of Series B Preferred Stock of the
Company issuable upon exercise of the warrants issued to the designees of the
placement agent of the Series B Offering described herein (the "Series B
Placement Warrants") and (b) exercise of warrants issued to the designees of the
placement agent for certain bridge financing transactions of the Company
described herein (the "Bridge Placement Warrants," and together with the Series
B Placement Warrants, the "Placement Warrants"). The number of shares of Common
Stock issuable upon conversion of the Series B Preferred Stock and upon exercise
of the Placement Warrants is subject to adjustment in certain events. This
Prospectus relates to the shares of Common Stock remaining to be sold in an
offering which commenced on July 7, 1997 for an aggregate of 7,047,788 shares of
Common Stock.

The Company will not receive any proceeds from the sale of shares of Common
Stock. The Company is not expected to receive any proceeds from the exercise of
the Placement Warrants since the Placement Warrants may be exercised pursuant to
a cashless exercise provision. In the event that the Placement Warrants are
exercised for cash, the Company intends to use such net cash proceeds (after
estimated expenses of this Offering of approximately $620,000) for general
working capital purposes. Proceeds, if any, from the exercise for cash of all
the Placement Warrants, before deduction of estimated expenses of this Offering,
would be approximately $160,000. Whether, how and to what extent any of the
Placement Warrants will be exercised, and whether the Placement Warrants are
exercised for cash or not, cannot be predicted by the Company.

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

The Company has informed the Selling Securityholders that the anti-manipulation
provisions of Regulation M promulgated under the Securities Exchange Act of 1934
may apply to the sales of their shares offered hereby. The Company also has
advised 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 December 31, 1997, had an accumulated deficit of approximately
$7,520,147. The Company is continuing to incur losses and expects to incur
significantly increasing additional losses for the foreseeable future.

The Common Stock is listed for quotation on the Nasdaq SmallCap Market under the
symbol "AVXT." The last reported sale price of the Common Stock on the Nasdaq
SmallCap Market on March 10, 1998, was $ 4.125 per share. The prices of the
Common Stock which may be obtained on 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

                                 COMPANY SUMMARY

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

In 1995, the Company licensed (the "TJU License") from Thomas Jefferson
University ("TJU") an issued U.S. patent and certain U.S. and foreign patent
applications covering a cancer vaccine containing a cancer patient's own
modified tumor cells, and a method for making and using such a vaccine. This
technology allows the Company to produce an autologous cell vaccine (an "AC
Vaccine") that attempts to stimulate the patient's immune system to eliminate
the cancer. This technology has emerged from research conducted at TJU and
primarily involves the removal of a patient's own tumor cells, modifying them
with 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-modified 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(TM), M-Vax(TM), is currently undergoing
physician-sponsored human clinical trials based on an experimental protocol at
TJU as an outpatient, post-surgical, adjunct therapy for the treatment of
melanoma, and is believed by the Company to be the first therapeutic cancer
vaccine to show a substantial increase in the survival rate for patients with
stage 3 melanoma. In such ongoing clinical trials at TJU, over 300 melanoma
patients have been treated post-surgically on an outpatient basis with M-Vax. In
62 patients with stage 3 melanoma in protocols in which there has been
sufficient time for long-term follow-up, the five-year survival rate is
approximately 60%. This compares with the historical and control group stage 3
survival rate of approximately 20%, and the survival rate for treatment with
high dose alpha interferon of approximately 32% in stage 3 patients whom the
Company believes to be comparable to those treated with M-Vax. In patients over
50 years old treated with M-Vax, the five-year survival rate was approximately
71%. In the over 300 patients treated in studies, the Company believes that only
relatively minor side effects, such as mild transient nausea and soreness and
swelling at the site of the application of the M-Vax vaccine, have been
witnessed to date.

David Berd, M.D., Professor of Medicine and Clinical Oncologist at TJU and the
inventor of the AC Vaccine technology, has conducted the ongoing clinical trials
at TJU pursuant to an FDA-approved, physician-sponsored Investigational New Drug
Application ("IND"). Following an earlier meeting with the FDA to discuss the
clinical results obtained with M-Vax, the use of such results in support of the
submission of a Company-sponsored IND to the FDA, and to review its proposed
development plan, the Company reviewed a proposed phase 3 protocol with FDA and
plans to submit a Company-sponsored IND to support the pivotal trial program.
This IND will also address product characterization/manufacturing issues raised
by the FDA to ensure that all pivotal data will support a product license
application. No patients will be enrolled in the pivotal trial program until the
Company and the FDA are satisfied that all product issues are resolved.
Depending upon the results of such clinical trials, it is the Company's
intention to use the results of these Company-sponsored clinical trials along
with the results of the clinical trial conducted at TJU, as the basis for the
filing of an application for the FDA approval to market M-Vax. The Company also
may pursue a similar regulatory approval and commercialization strategy for
M-Vax in Australia, Canada, Mexico and certain other countries through corporate
partnering strategies, although such strategies have not yet been finalized or
initiated.

Denial of any regulatory approvals or any significant delays in obtaining any
of the same would have a material adverse effect on the Company.

The Company also believes that the AC Vaccine technology may have
applications in the treatment of other cancers, which may include ovarian,
breast, prostate, lung and colorectal cancers and acute myelogenous leukemia
(AML). The Company intends to fund the preclinical and initial clinical
development of this technology for at least some of these indications.
Accordingly, in addition to continuing the clinical work on M-Vax, the
Company has also entered into a sponsored research agreement with TJU
relating to the development of additional immunotherapies based on the AC
Vaccine technology. For example, the Company is treating post-surgical stage
3 patients in its Phase I/II clinical trial of O-Vax(TM), its AC Vaccine for
ovarian cancer. This trial is being conducted at TJU under the direction of
Dr. David Berd and has already shown a positive immune response, as measured
by a delayed type hypersensitivity (DTH) test, in the first seven of seven
patients treated. The Company also plans to initiate a similar Phase I/II
clinical trial of C-Vax(TM), its AC Vaccine for colorectal cancer, within the
next year.

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

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

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

                                  RISK FACTORS

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

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

The Company has incurred substantial operating losses since its inception. As of
December 31, 1997, the Company's accumulated deficit was approximately
$7,520,147. The Company expects to incur significant increasing operating losses
over the next several years, primarily due to the expansion of its research and
development programs, including clinical trials for M-Vax(TM) , O-Vax(TM),
C-Vax(TM) and preclinical studies and clinical trials for other products that it
may acquire or develop. The Company's ability to achieve profitability depends
upon, among other things, its ability to develop products, obtain regulatory
approval for its proposed products, and enter into agreements for product
development, manufacturing and commercialization. The Company's M-Vax , O-Vax
and C-Vax products do not currently generate revenue and the Company does not
expect to achieve revenues from these or other products for the foreseeable
future. Moreover, there can be no assurance that the Company will ever achieve
significant revenues or profitable operations from the sale of M-Vax, O-Vax,
C-Vax, 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, officers, directors and consultants of the Company, the
Company has granted such employees, officers, directors and consultants 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,
officers, directors and consultants of the Company, may dilute the value of the
Common Stock. See "Management" and "Description of Securities--1992 Stock Option
Plan; Other Options."

DEVELOPMENT STAGE COMPANY

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

TECHNOLOGICAL UNCERTAINTY AND EARLY STAGE OF PRODUCT DEVELOPMENT

The technologies and products which the Company intends to develop are in the
early stages of research and development, require significant further research,
development and testing and are subject to the risks of failure inherent in the
development of products based on innovative or novel technologies. These risks
include, but are not limited to, the possibility that any or all of the
Company's proposed products will be found to be ineffective or unsafe, that the
products once developed, although effective, are uneconomical to market, that
third parties hold proprietary rights that preclude the Company from marketing
such products or that third parties market a superior or equivalent product and
that the Company will be unable to secure a meaningful patent position for such
products. See "Uncertainty Regarding Patents and Proprietary Rights." The
results of initial preclinical and clinical testing of the Company's current and
proposed products under development are neither necessarily predictive of
results that will be obtained from subsequent or more extensive preclinical and
clinical testing nor necessarily acceptable to the United States Food and Drug
Administration (the "FDA") or other similar agencies to support applications for
marketing permits.

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

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

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



                                       8
<PAGE>

GOVERNMENT REGULATION; NO ASSURANCE OF PRODUCT APPROVAL

The proposed products of the Company will be subject to very stringent federal,
state and local government regulations, including, without limitation, the
Federal Food, Drug and Cosmetic Act, and its state and local counterparts.
Similar regulatory frameworks exist in other countries where the Company may
consider marketing its products. To date, TJU and Dr. David Berd, the inventor
of the AC Vaccine technology, have conducted the ongoing clinical trials at TJU
pursuant to an FDA-approved physician sponsored Investigational New Drug
Application ("IND"). The Company met earlier with the FDA to discuss the
clinical results obtained with M-Vax, the use of such results in support of the
submission of a Company-sponsored IND to the FDA, and to review its proposed
development program, which includes Phase III clinical trials for M-Vax. Prior
to marketing M-Vax, O-Vax, C-Vax, 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 extensive 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. In
the U.S., clinical trials are stringently regulated by the FDA, and the FDA may
suspend clinical trials at any time if it determines that patients are being
exposed to an unreasonable health risk, or for certain other reasons. 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. In addition, new
government regulations may be established that could delay or prevent regulatory
approval of the Company's products under development. 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 regulatory
approval is obtained, the uses for which any products may be marketed will be
limited to specific indications. Following regulatory approval, if any, a
marketed product and its manufacturer are subject to continual regulatory review
and periodic inspections. In the U.S., the Company would be required to comply
with FDA requirements for manufacturing, labeling, advertising, record keeping
and reporting of adverse experiences and other information. In addition, the
Company would be required to comply with federal and state health care
anti-kickback laws and other health care fraud and abuse laws that pertain to
the marketing of pharmaceuticals. Failure to comply with regulatory requirements
could subject the Company to administrative or judicial enforcement actions,
including but not limited to product seizures, injunctions, civil penalties,
criminal prosecution, refusals to approve new products or withdrawal of existing
approvals, as well as increased product liability exposure, any of which could
have a material adverse affect on the Company. Development and marketing of the
Company's products outside the U.S. will be subject to foreign regulatory
requirements governing clinical trials, marketing approval, manufacturing and
pricing. Failure to comply with these requirements could result in enforcement
actions or penalties or could delay introduction of the Company's products in
certain countries.

Failure of the Company to obtain and maintain regulatory approval of its
proposed products, processes or facilities would have a material adverse effect
on the business, financial condition and results of operations of the Company.
In addition, many academic institutions and companies doing research in the
field of cancer immunotherapy are using a variety of approaches and
technologies. Any adverse results obtained by such researchers in preclinical or
clinical studies, even if not directly or indirectly related to the Company's
potential products or approaches, could adversely affect the regulatory
environment for immunotherapy or other biotechnology products generally, and
possibly lead to delays in the approval process for the Company's potential
products. See "Business--Government Regulation."

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

The Company anticipates that it may in the future seek to enter into
collaborative agreements with pharmaceutical, or other biotechnology companies,
for the development of, clinical testing of, seeking of regulatory approval for,
and manufacturing, marketing and commercialization of, certain of its products.
The Company may in the future grant to its collaborative partners, if any,
rights to license and commercialize any pharmaceutical products developed under
these collaborative agreements and such rights would limit the Company's
flexibility in considering alternatives for the commercialization of such
products. Under such agreements, the Company may rely on such 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 such collaborative partners might
have an



                                       9
<PAGE>


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.

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

The Company currently does not have the resources to commercially manufacture,
directly market or sell M-Vax, O-Vax, C-Vax, 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. While the Company is in the process of
establishing commercial scale manufacturing facilities, such endeavor will
require substantial additional funds, the hiring and retention of significant
additional personnel and compliance with extensive regulations applicable to
such a facility. There can be no assurance that the Company will be able to
successfully establish such a facility, hire such personnel or successfully
manufacture products for sale at competitive prices. See
"Business--Manufacturing and Marketing."

DEPENDENCE ON LICENSES AND SPONSORED RESEARCH AGREEMENTS

The Company relies heavily on third parties for a variety of functions,
including certain functions relating to research and development. As of March 3,
1998, the Company had only six full-time employees. The Company is party to
several license and research agreements which place substantial responsibility
on the Company's licensors for research and clinical development of its products
and technologies.

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

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

If the Company does not meet its financial, development, or other obligations in
a timely manner under its license agreements or related sponsored research
agreements, the Company could lose the rights to its proprietary technology or
the right to have its licensors and others conduct its research and development
efforts, any of which could have a material adverse effect on the Company. TJU
has the right to terminate the R&D agreement on 30 days' written notice if it
becomes unable for any reason to complete the Study.



                                       10

UNCERTAINTY REGARDING PATENTS AND PROPRIETARY RIGHTS

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

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

In the event a third party has filed a patent application relating to an
invention claimed in a Company patent application, the Company or its licensor
may be required to participate in an interference proceeding in the United
States Patent and Trademark Office to determine priority of the invention, which
could result in substantial uncertainties and cost for the Company, even if the
eventual outcome is favorable to the Company. An adverse outcome could subject
the Company to significant liabilities to third parties and require the Company
to license disputed rights from third parties at an undeterminable cost or to
cease using the technology. In addition to patent litigation and interferences,
a third party may at some time seek to have a patent of the Company reexamined
in the Patent Office on the basis of prior art. The Company, or a licensor of
the Company, may also at some time seek reexamination, or reissue, of a Company
patent. An application for reissue is being made for the purpose of
strengthening the TJU patent in light of a prior art reference which may have a
material adverse impact on the patent. Although the Company believes that there
is a sound basis for this reissue application, there can be no assurance that a
patent will issue from the application, or that any such patent will be
enforceable and will not be challenged, invalidated, or circumvented. There can
be no assurance that the validity or enforceability of the Company's patents and
its applications, if issued, would be upheld by a court.

While no patent that could be potentially infringed by manufacture, use or sale
of the Company's product candidates has come to the attention of the Company,
the Company's product candidates are still in the development stage, and neither
their formulations nor their method of manufacture have been finalized. Thus,
there can be no assurance that the manufacture, use or sale of the Company's
product candidates will not infringe patent rights of others. The Company may be
unable to avoid infringement of any such patents and may have to seek a license,
defend an infringement action, or challenge the validity of the patents in
court. There can be no assurance that a license will be available to the
Company, if at all, upon terms and conditions acceptable to the Company or that
the Company will prevail in any patent litigation. Litigation may be necessary
to defend or enforce the Company's patent and license rights or to determine the
scope and validity of others' proprietary rights. Defense and enforcement of
patent claims can be expensive and time consuming, even in those instances in
which the outcome is favorable to the Company, and can result in the diversion
of substantial resources from the Company's other activities. There can be no
assurance that the Company will have sufficient resources to pursue such
litigation. If the Company does not obtain a license under any such patents, is
found liable for infringement, or is not able to have them declared invalid, the
Company may be liable for significant money damages, may encounter significant
delays in bringing products to market, or may be precluded from participating in
the manufacture, use or sale of


                                       11
<PAGE>


products or methods of treatment covered by such patents, any of which could
have a material adverse effect on the Company's business, results of operation
and financial condition. See "Business-- Proprietary Technology."

In its product development activities, the Company relies substantially on
certain technologies which are not patentable or proprietary and are therefore
available to the Company's competitors. The Company also relies on certain
proprietary trade secrets and know-how which are not patentable. Although the
Company has taken steps to protect its unpatented trade secrets and know-how, in
part through the use of confidentiality agreements with its employees,
consultants and certain of its contractors, there can be no assurance that these
agreements will not be breached, that the Company would have adequate remedies
for any breach or that the Company's trade secrets will not otherwise become
known or be independently developed or discovered by competitors. If the
Company's employees, scientific consultants or collaborators develop inventions
or processes independently that may be applicable to the Company's product
candidates, disputes may arise about ownership of propriety rights to those
inventions and processes. Such inventions and processes will not necessarily
become the Company's property, but may remain the property of those persons or
their employers. Protracted and costly litigation could be necessary to enforce
and determine the scope of the Company's proprietary rights. Failure to obtain
or maintain patent and trade secret protection, for any reason, could have a
material adverse effect on the Company. Certain of the Company's patents are
directed to inventions developed within academic institutions (from which the
Company earlier acquired rights to such patents) with funds from United States
government agencies. As a result of these arrangements, the United States
government may have rights in certain inventions developed during the course of
the performance of federally funded projects as required by law or agreements
with the funding agency. Several bills affecting patent rights have been
introduced in the United States Congress. These bills address various aspects of
patent law, including publication, patent term, re-examination, subject matter
and enforceability. It is not certain whether any of these bills will be enacted
into law or what form new laws may take. Accordingly, the effect of legislative
change on the Company's intellectual property rights is uncertain.

CONDUCTING BUSINESS ABROAD

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

For clinical investigation and marketing outside the United States, the Company
also is subject to foreign regulatory requirements governing human clinical
trials and marketing approval for drugs. The requirements governing the conduct
of clinical trials, product licensing, pricing and reimbursement vary widely for
European countries both within and outside the European Union ("EU"). Outside
the United States, the Company's ability to market a product is contingent upon
receiving a marketing authorization from the appropriate regulatory authority.
At present, foreign marketing authorizations are applied for at a national
level, although with the EU certain registration procedures are available to
companies wishing to market their products in more than one EU 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 EU 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
EU. Other products will be registered by national authorities in individual EU
member states, operating on a principle of mutual recognition. This foreign
regulatory approval process includes, at least, all of the risks associated with
FDA approval set forth above. The Company could possibly have greater difficulty
in obtaining any such approvals and also might find it more difficult to protect
its intellectual property abroad.

DEPENDENCE UPON KEY PERSONNEL AND CONSULTANTS

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

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

LACK OF MANUFACTURING FACILITIES

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

The Company currently has interim manufacturing capacity which it believes is
reasonably adequate to support the commencement of the clinical programs and
expects to expand its manufacturing staff and facilities, to establish an
additional facility or facilities and to contract with third parties to assist
it with production. There can be no assurance that the Company will be able to
obtain from third party manufacturers adequate supplies in a timely fashion for
commercialization, or that commercial quantities of any such products, if
approved for marketing, will be available from contract manufacturers at
acceptable costs. In the event the Company proceeds with establishing a
full-scale commercial manufacturing facility, the Company will require
substantial additional funds and will be required to hire and train significant
numbers of employees and comply with the extensive regulations applicable to
such a facility. There is no assurance that AVAX will be able to develop a
current Good Manufacturing Practices ("cGMP") manufacturing facility sufficient
for all clinical trials or commercial-scale manufacturing. The cost of
manufacturing certain products may make them prohibitively expensive. In
addition, in order to successfully commercialize its product candidates, the
Company may be required to reduce the cost of production, and there can be no
assurance that the Company will be able to do so. See "Business--Manufacturing
and Marketing."

COMPETITION

The Company's proposed cancer immunotherapy business is characterized by
intensive research efforts and intense competition. Many companies, research
institutes, hospitals and universities are working to develop products and
processes in the Company's fields of research. Most of these entities have
substantially greater financial, technical, manufacturing, marketing,
distribution and other resources than the Company and include, among others,
Schering Plough Corporation, Chiron Corporation, Bristol-Myers Squibb and
Johnson & Johnson. Certain of such companies have


                                       13
<PAGE>


experience in undertaking testing and clinical trials of new or improved
products similar in nature to that which the Company is developing. In addition,
certain competitors have already begun testing similar compounds or processes
and may introduce such products or processes before the Company. Accordingly,
other companies may succeed in developing products earlier than the Company or
that are more effective than those proposed to be developed by the Company.
Further, it is expected that competition in the Company's field will intensify.
There can be no assurance that the Company will be able to compete successfully
in the future. See "Business--Competition."

RISK OF PRODUCT LIABILITY

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

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

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

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

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

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



                                       14
<PAGE>

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

CONTROL BY CURRENT OFFICERS, DIRECTORS AND PRINCIPAL STOCKHOLDERS

The Company's directors, executive officers and principal stockholders
beneficially own approximately 31% 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 direction and policies of the Company and, if they choose to act in
concert, 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 March 3, 1998, 4,777,488 shares of Common Stock were issued and
outstanding of which the Company believes that, other than those shares
registered in this Offering, only 1,487,822 shares of Common Stock are
"restricted securities" and under certain circumstances may, in the future, be
sold in compliance with Rule 144 under the Securities Act of 1933 (the "Act"),
unless they are held by "affiliates" of the Company as that term is used under
the Act. In general, under Rule 144 as currently in effect, subject to the
satisfaction of certain conditions and certain manner of sale and notice
requirements, including the requirement that there is adequate current public
information with respect to the Company as contemplated by Rule 144, a person
(or persons whose shares are aggregated), including persons who may be deemed an
affiliate of the Company as that term is defined under the Act, who beneficially
owned restricted shares of Common Stock for at least one year is entitled to
sell, within any three-month period, a number of shares that does not exceed (i)
the greater of one percent of the total number of outstanding shares of the same
class, or (ii) the average weekly trading volume during the four calendar weeks
immediately preceding the sale. A person who presently is not and who has not
been an affiliate of the Company for at least three months immediately preceding
the sale and who has beneficially owned the shares of Common Stock for at least
two years is entitled to sell such shares under Rule 144(k) without regard to
the volume limitations described above.



                                       15
<PAGE>

In addition, the Company has issued and outstanding, or issuable, warrants and
options to purchase an aggregate of 2,793,351 shares of Common Stock (excluding
49,229 shares of Common Stock underlying Series B Placement Warrants and Bridge
Placement Warrants that are being registered in this Offering). Any employee,
officer or director of the Company who acquired his or her shares prior to the
effective date of the Registration Statement at a time when the Company was not
subject the reporting requirements of Section 13 or 15(d) of the Securities
Exchange Act of 1934 (the "Exchange Act") or who holds vested options as of the
effective date of the Registration Statement, pursuant to a written compensatory
plan or contract is entitled to rely on the resale provisions of Rule 701. Rule
701 permits non-affiliates to sell their Rule 701 shares without having to
comply with the public information, holding period, volume limitation or notice
provisions of Rule 144 and permits affiliates to sell their Rule 701 shares
without having to comply with Rule 144's holding period restrictions, in each
case commencing 90 days after the effective date of the Registration Statement.

The Company also has 5,130,681 shares of Common Stock that are issuable upon
conversion of Series B Preferred Stock. Certain of the stockholders and holders
of shares of Common Stock issuable upon exercise of Series B Preferred Stock
(including shares of Common Stock issuable upon conversion of shares of Series B
Preferred Stock issuable upon exercise of Series B Placement Warrants), and
other warrants of the Company, have certain demand and piggyback registration
rights. The Company's current Registration Statement, to which this Prospectus
relates, pertains to the resale of up to 6,355,248 shares of Common Stock and
the Company may, in the future, agree to register other shares of Common Stock
held by eligible persons' including officers of the Company, on Form S-8
relating to shares of Common Stock issuable upon exercise of such persons' stock
options or warrants, including, without limitation, under its 1992 Stock Option
Plan. See "Description of Securities--1992 Stock Option Plan", "Other Options",
"Warrants" and "Registration Rights". Exercise of any registration rights could
involve substantial expense to the Company.

In addition, the vesting dates for the shares issuable upon exercise of the
Company's stock options are also subject to acceleration under certain
circumstances, including certain changes in control of the Company, subject to
certain exceptions.

Holders of the Company's warrants and options are likely to exercise them when,
in all likelihood, the Company could obtain additional capital on terms more
favorable than those provided by warrants and options. Further, while these
warrants and options are outstanding, the Company's ability to obtain additional
financing on favorable terms may be affected adversely by the presence of such
securities and the terms thereof. No prediction can be made as to the effect, if
any, that the availability of such shares for sale will have on the market
prices that may be quoted from time to time on the Nasdaq Smallcap Market.
Nevertheless, the possibility that substantial amounts of the Common Stock may
be sold in the public market may adversely affect the prevailing market prices
for the Common Stock and could impair the Company's ability to raise capital in
the future through the sale of equity securities. Actual sales or the prospect
of future sales of shares of the Common Stock, whether such shares are
"restricted shares" under Rule 144, or are otherwise eligible for resale without
restriction, may have a depressive effect upon the price of the Common Stock and
the market therefor.

LIMITED PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK PRICE

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

UNCERTAINTY OF LISTING ON NASDAQ SMALLCAP MARKET; MARKET ILLIQUIDITY

Although the Common Stock has been approved for initial listing and quotation on
the Nasdaq SmallCap Market, such market has recently adopted stricter continuing
listing criteria, which the Company is required to meet. Accordingly, continued
inclusion of the Common Stock on the Nasdaq SmallCap Market pursuant to the
recently adopted stricter standards requires that: (i) the Company have net
tangible assets of $2,000,000, or a market capitalization of $35 million or
more, or net income in two of the three most recent fiscal years of at least
$500,000; (ii) the Company's public float have a market value of at least $1
million and a public float of at least 500,000 shares; (iii) the minimum bid
price for the Common Stock be at least $1.00 per share; (iv) the Common Stock
have at least two active market makers and be held of record by at least 300
shareholders and (v) the Company adhere to certain corporate governance
provisions. . For purposes of determining compliance with the public float
requirements, shares of stock held by officers, directors and 10%-or-greater
stockholders are excluded. There can be no assurance that the Company and the
Common Stock will continue to satisfy the requirements for maintaining a listing
on the Nasdaq SmallCap Market.

If the Company is unable to satisfy the continuing maintenance requirements as
they may be in effect or applied from time to time, the Common Stock may be
delisted from the Nasdaq SmallCap Market. In such event, trading, if any, in the
Common Stock would thereafter probably be conducted on the OTC Bulletin Board or
in the over-the-counter market through the National Quotation Bureau (the "pink
sheets") and the Company would again be required to comply with the Nasdaq
SmallCap Market's initial listing criteria in order to have the Common Stock
re-approved for listing and quotation thereon. Consequently, the liquidity of
the Common Stock could be impaired materially and adversely, not only in the
number of securities that can be bought and sold at a given price, but also
through delays in the timing of transactions and reduction in security analysts'
and media coverage of the Company, which could result in lower prices for the
Common Stock than might otherwise be attained and could also result in a larger
spread between the bid and asked prices for the Common Stock. See "Risks of Low
Price Stock; Possible Effect of "Penny Stock" Rules on Liquidity for the Common
Stock."

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

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

In addition, if the Common Stock fails to meet the minimum market price, the net
tangible asset or the annual revenue tests set forth above, but is quoted on the
OTC Bulletin Board (as to which there can be no assurance), then trading in the


                                       17
<PAGE>


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

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

The Company's Articles of Incorporation, as amended, authorize the issuance of
up to 5,000,000 shares of preferred stock, par value $.01 per share, of which
300,000 shares are authorized for issuance as shares of Series B Preferred
Stock, of which approximately 196,677 are issued and outstanding as Series B
Preferred Stock or reserved for issuance upon the exercise of Series B Placement
Warrants. The Company's Certificate of Incorporation authorizes the issuance of
"blank check" preferred stock with such designation, rights and preferences as
may be determined from time to time by the Board of Directors. Accordingly, the
Board of Directors is empowered, without stockholder approval, to issue a new
series of preferred stock with dividend, liquidation, conversion, voting or
other rights which could adversely affect the voting power or other rights of
the holders of the Common Stock. In the event of issuance, the new series of
preferred stock could be utilized, under certain circumstances, as a method of
discouraging, delaying or preventing a change in control of the Company.
Although the Company has no present intention to issue any additional shares of
its preferred stock, other than those already authorized for issuance upon
exercise of the Placement Warrants, there can be no assurance that the Company
will not do so in the future. See "Description of Securities."

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

POTENTIAL CONVERSION PRICE RESET OF SERIES B PREFERRED STOCK

In May and June 1996, the Company consummated an offering of units consisting of
shares of Series B Preferred Stock and Common Stock. The 259,198 shares of
Series B Preferred Stock sold in such offering were convertible at the option of
the holders thereof into shares of Common Stock, at an initial conversion rate
of 25 shares of Common Stock per share of Series B Preferred Stock,
corresponding to a conversion price equal to $4.00 per share (the "Initial
Conversion Price"). As of June 11, 1997, 13,250 shares of Series B Preferred
Stock had been converted to Common Stock. The Initial Conversion Price was
adjusted effective June 11, 1997, because the average closing bid price of the
Common Stock for the 30 consecutive trading days immediately preceding such date
was less than $5.40. The average was, in fact, $5.175 per share. Accordingly,
the conversion price was adjusted to $3.83 per share, which corresponds to a new
conversion rate of 26.0875 shares of Common Stock per share of Series B
Preferred Stock. The conversion price (and, consequently the number of shares of
Common Stock issuable upon conversion) is subject to further adjustment upon the
occurrence of certain events. See "Description of Securities--Conversion." Any
such reset of the conversion price applicable to the Series B Preferred Stock
would result in the issuance of additional shares of Common Stock upon
conversion of the Series B Preferred Stock, and would have a dilutive effect on
purchasers of the Common Stock offered hereby.

In addition, in consideration for their agreement to extend the "lock-up"
provisions described below which are applicable to the shares of Common Stock
issuable upon conversion of the Series B Preferred Stock, certain holders of
shares of Series B Preferred Stock are entitled to be issued additional shares
of Common Stock upon the happening of certain events.


                                       18
<PAGE>


See "Description of Securities--Lock-Up." The occurrence of such an event and
the issuance of the additional shares of Common Stock would have a dilutive
effect on purchasers of the Common Stock offered hereby.

FORWARD LOOKING STATEMENTS

Certain written and oral statements made or incorporated by reference by the
Company or its representatives in this Prospectus, other reports and filings
with the Commission, press releases, conferences or otherwise, are "forward
looking statements", within the meaning of the Private Securities Litigation
Reform Act of 1995 ("PSLRA") and Section 27A of the Securities Act of 1933 and
Section 21E of the Securities Exchange Act of 1934. Forward-looking statements
include, without limitation, any statement that may predict, forecast, indicate,
or imply future results, performance or achievements, and may contain the words
"estimate", "project", "intend", "forecast", "anticipate", "plan", "planning",
"expect", "believe", "will", "will likely", "should", "could", "would", "may" or
words or expressions of similar meaning. In addition, except for historical
matters, certain other statements set forth in this Prospectus and elsewhere by
the Company from time to time, including, without limitation, the Company's
research and development programs, the possible filing of INDs or marketing
applications for M-Vax, O-Vax, C-Vax, or any other products the Company may
develop, the seeking of joint development or licensing arrangements with
pharmaceutical companies, the research and development of particular compounds
and technologies for particular indications and the period of time for which the
Company's existing resources will enable the Company to fund its operations and
to meet the continuing listing requirements for the quotation of its securities
on the Nasdaq SmallCap Market and the possibility of contracting with other
parties additional licenses to develop, manufacture and market commercially
viable products, are forward-looking statements within the meaning of the PSLRA.
Such forward-looking statements are based upon the Company's current belief as
to the outcome, occurrence and timing of future events or current expectations
and plans based upon, among other things, assumptions made by, and information
currently available to management, including management's own knowledge and
assessment of the Company's industry, competition and current regulatory
environment. 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

YEAR 2000

Pursuant to the Company's Year 2000 Plan, the Company is currently evaluating
its computerized systems to assure that the transition to the Year 2000 will not
disrupt the Company's operations. The Company also intends to evaluate the
systems of its key suppliers, vendors and other collaborators. Presently, the
Company does not believe that Year 2000 compliance will result in material
investments by the Company, nor does the Company anticipate that the so-called
Year 2000 problem will have any material adverse effect on the business,
operations or financial performance of the Company.

There can be no assurance, however, that the Year 2000 problem will not
adversely affect the Company and its business, particularly in an indirect
manner by virtue of any problems encountered by third parties with whom it does
business.

NO DIVIDENDS

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

                                 USE OF PROCEEDS

The Company will not receive any proceeds from the sale of shares of Common
Stock. The Company is not expected to receive any proceeds from the exercise of
the Placement Warrants since the Placement Warrants may be exercised pursuant to
a cashless exercise provision. In the event that the Placement Warrants are
exercised for cash, the Company intends to use such net cash proceeds (after
estimated offering expenses of this Offering of approximately $620,000) for
general working capital purposes. Proceeds, if any, from the exercise for cash
of all the Placement Warrants, before deduction of estimated expenses of this
Offering, would be approximately $160,000. Whether, how and to what extent any
of the Placement Warrants will be exercised, and whether the Placement Warrants
are exercised for cash or not, cannot be predicted by the Company.

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

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 $7,520,147 as of
December 31, 1997. The Company expects to incur significantly increasing
operating losses over the next several years, primarily due to the expansion of
its research and development programs, including clinical trials for M-Vax,
O-Vax, C-Vax and other preclinical studies and clinical trials for other
products that may arise from the AC Vaccine technology and from the compounds
licensed from Rutgers and Texas A&M and other products that it may acquire or
develop.

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

PLAN OF OPERATION

The Company is currently engaged in the development and commercialization of
biotechnology and pharmaceutical products and technologies. In November 1995,
the Company acquired the rights to the AC Vaccine technology pursuant to the TJU
License. The Company initially intends to be engaged primarily in the
development and commercialization of the AC Vaccine technology, as well as the
potential anti-cancer and anti-infective technology licensed pursuant to the
Rutgers License and the potential anti-cancer technology licensed pursuant to
the Texas A&M License. See "Business." The Company anticipates that during the
next 12 months it will conduct substantial research and development of the AC
Vaccine technology, including, without limitation, Phase III clinical trials on
M-Vax, the Company's lead AC Vaccine technology for metastatic melanoma. The
Company also anticipates that it will expend substantial resources on the
research and development of that same technology for the treatment of other
cancers, which may include ovarian, breast, prostate, lung and colorectal cancer
and acute myelogenous leukemia (AML). For example, the is treating post-surgical
stage 3 patients in its Phase I/II clinical trial of O-Vax, its AC Vaccine for
ovarian cancer. This trial is being conducted at TJU under the direction of Dr.
David Berd. The Company also plans to initiate a similar Phase I/II clinical
trial of C-Vax, its AC Vaccine for colorectal cancer, within the next 12 months.
It is also expected that during the next 12 months, in order to support these
clinical trial efforts, the Company will be required to expend substantial
resources on the establishment of laboratory facilities for the manufacture of
its products. See "Business--Technology Applications and Product Candidates,"
"Research and Development" and "Manufacturing and Marketing."

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

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


                                       23
<PAGE>


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.

During the last 12 months, the Company's Research and Development and General
and Administrative expenses increased significantly from $.7 to $2.4 million and
from $1.3 to $2.7 million, respectively. These increases relate primarily to the
progress made in preparing the AC Vaccine technology for phase III clinical
trials in melanoma, commencement of a proof-of-concept study in ovarian cancer
with the same technology and completion of a Class 10,000 "clean room"
laboratory for clinical manufacturing of the vaccine. Research and development
costs also increased due to the licensing of the topoisomerase inhibitor
compounds from Rutgers and the licensing of the anti-estrogen compounds from
Texas A&M. General and administrative expenses also increased due to the
completion of the registration of the shares issued in the Company's 1996
private placement and the listing of such shares on the Nasdaq Small Cap Market.
The Company anticipates that, over the next 12 months, expenses will continue to
increase, particularly as development proceeds with the AC Vaccine and the
Rutgers and Texas A&M compounds.

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

LIQUIDITY AND CAPITAL RESOURCES

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

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

In June 1997, the Financial Accounting Standards Board (FASB) issued Statement
No. 130, Reporting Comprehensive Income, which is effective for years beginning
after December 15, 1997, and will be adopted by the Company in 1998. The
Statement establishes standards for the reporting and display of comprehensive
income and its components in a full set of general purpose financial statements.
Management does not believe that this Statement will have any impact on the
results of operations or the financial position of the Company.

                                    BUSINESS

GENERAL

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

In 1995, the Company licensed (the "TJU License") from Thomas Jefferson
University ("TJU") an issued U.S. patent and certain U.S. and foreign patent
applications covering a cancer vaccine containing a cancer patient's own
modified tumor cells, and a method for making and using such a vaccine. This
technology allows the Company to produce an autologous cell vaccine (an "AC
Vaccine") that attempts to stimulate the patient's immune system to eliminate
the cancer. This technology has emerged from research conducted at TJU and
primarily involves the removal of a patient's own tumor cells, modifying them
with 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(TM), M-Vax(TM), is currently undergoing
physician-sponsored human clinical trials based on an experimental protocol at
TJU as an outpatient, post-surgical, adjunct therapy for the treatment of
melanoma, and is believed by the Company to be the first therapeutic cancer
vaccine to show a substantial increase in the survival rate for patients with
stage 3 melanoma. In such ongoing clinical trials at TJU, over 300 melanoma
patients have been treated post-surgically on an outpatient basis with M-Vax. In
62 patients with stage 3 melanoma in protocols in which there has been
sufficient time for long-term follow-up, the five-year survival rate is
approximately 60%. This compares with the historical and control group stage 3
survival rate of approximately 20%, and the survival rate for treatment with
high dose alpha interferon of approximately 32% in stage 3 patients whom the
Company believes to be comparable to those treated with M-Vax. In patients over
50 years old treated with M-Vax, the five-year survival rate was approximately
71%. In the over 300 patients treated in studies, the Company believes that only
relatively minor side effects, such as mild transient nausea and soreness and
swelling at the site of the application of the M-Vax vaccine, have been
witnessed to date. Based on these results, and following a meeting with the FDA
to discuss its development plans, the Company plans to conduct two pivotal Phase
III multi-center clinical trials of M-Vax.

The Company also believes that the AC Vaccine technology may have applications
in the treatment of other cancers, which may include ovarian, breast, prostate,
lung and colorectal cancers and acute myelogenous leukemia (AML). The Company
intends to fund the preclinical and initial clinical development of this
technology for at least some of these indications. Accordingly, in addition to
continuing the clinical work on M-Vax, the Company has also entered into a
sponsored research agreement with TJU relating to the development of additional
immunotherapies based on the AC Vaccine technology. For example, the Company is
treating post-surgical stage 3 patients in its Phase I/II clinical trial of
O-Vax(TM), its AC Vaccine for ovarian cancer. This trial is being conducted at
TJU under the direction of Dr. David Berd and has already shown a positive
immune response, as measured by a delayed type hypersensitivity (DTH) test, in
the first seven of seven patients treated. The Company also plans to initiate a
similar Phase I/II clinical trial of C-Vax(TM), its AC Vaccine for colorectal
cancer, within the next year.

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



                                       25
<PAGE>

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

BACKGROUND AND SCIENTIFIC RATIONALE OF THE AC VACCINE TECHNOLOGY

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

As of 1997, the National Cancer Institute (NCI) estimates that approximately 7.4
million people living in the United States were diagnosed as having cancer. The
incidence of cancer continues to increase. The NCI also estimates that the
overall cost to the health care system of treating these patients is
approximately $104 billion. The Company is aware of estimates that deaths from
cancer will surpass cardiovascular mortality worldwide by the end of the
century.

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

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

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

TECHNOLOGY APPLICATIONS AND PRODUCT CANDIDATES

THE AC VACCINE TECHNOLOGY

The Company's primary proprietary technology is a patented 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
modifying a larger molecule with a smaller 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-modified tumor
antigen may be followed by the development of an immune response to the
unmodified tumor antigen, somewhat analogous to the phenomenon of drug-induced
autoimmune disease. Therefore, the process of haptenizing a patient's tumor
cells may allow the unhaptenized cancer cells to be recognized by the body's
immune system leading to an immune response against the patient's tumor cells
and their potential elimination from the body.

In practice, the Company's initial therapy would be used as an adjunct to
surgical treatment of tumors. In one proposed model, the surgeon would remove
the patient's tumor and send the cells to the Company where they would be
processed and stored. The vaccine would then be created and sent to the
patient's doctor as each dose is required for administration of the vaccine on
an outpatient basis. The patient's response to the treatment would then be
monitored using standard protocols.

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

M-VAX

GENERAL. The Company's lead product, M-Vax, is a post-surgical treatment for
stage 3 melanoma. Melanoma is a highly malignant tumor that can spread so
rapidly that it can be fatal within months of diagnosis. The incidence of
melanoma is increasing at a faster rate than most other cancers in the United
States, Australia, northern Europe and Canada. Although there are several
causative factors, rising exposure by the general population to UV radiation in
sunlight appears to be the most significant factor behind this increase. With
the incidence growing at a rate in excess of 6% annually, it is estimated that
melanoma affects over 200,000 people in the United States, with approximately
40,300 new cases diagnosed in 1997.

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

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

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

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

o Stage 4--distant metastasis.

Surgical excision of the tumor mass and any of the nearby lymph nodes into which
there has been metastasis, followed by high dose alpha interferon, which is
currently the only FDA-approved treatment for patients with stage 3 melanoma.
However, in many cases survival is restricted by the inability of surgery to
guarantee removal of all the tumor cells. It is highly possible for the patient
to remain with undetected metastasis. Further, use of high dose alpha interferon
is associated with many severe side effects, often leading to either reduction
in dosage or complete discontinuation before the full course of treatment is
completed. Due to its limited efficacy and highly toxic side effects,
chemotherapy and radiation have not been widely used in the treatment of these
patients. The five-year survival rate for these patients is believed by the
Company to be approximately 20%. Recently, the FDA approved the use of high dose
alpha interferon for the post-surgical treatment of melanoma patients. In
clinical studies alpha interferon has demonstrated a five-year survival rate



                                       27
<PAGE>


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

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

In such ongoing clinical trials at TJU, over 300 melanoma patients have been
treated post-surgically on an outpatient basis with M-Vax. In 62 patients with
stage 3 melanoma in protocols in which there has been sufficient time for
long-term follow-up, the five-year survival rate is approximately 60%. This
compares with the historical and control group survival rates of about 20%, and
the survival rate for treatment with high dose alpha interferon of approximately
32% in stage 3 patients whom the Company believes to be comparable to those
treated with M-Vax. In patients over 50 years old treated with M-Vax, the
five-year survival rate was approximately 71%. The Company believes that the
results to date of the ongoing clinical trial represent the first substantial
increase in survival for stage 3 melanoma patients treated by immunotherapy. In
the over 300 patients treated in studies, the Company believes that only
relatively minor side effects, such as soreness and mild transient nausea and
swelling at the site of the application of the M-Vax vaccine, have been
witnessed to date.

David Berd, M.D., Professor of Medicine and Clinical Oncologist at TJU and the
inventor of the AC Vaccine technology, has conducted the ongoing clinical trials
at TJU pursuant to an FDA-approved, physician-sponsored Investigational New Drug
Application ("IND"). Following an earlier meeting with the FDA to discuss the
clinical results obtained with M-Vax, the use of such results in support of the
submission of a Company-sponsored IND to the FDA, and to review its proposed
development plan, the Company reviewed a proposed phase 3 protocol with the FDA
and plans to submit a Company-sponsored IND to support the pivotal trial
program. This IND will also address product characterization/manufacturing
issues raised by the FDA to ensure that all pivotal data will support a product
license application. No patients will be enrolled in the pivotal trial program
until the Company and the FDA are satisfied that all product issues are
resolved. Depending upon the results of such clinical trials, it is the
Company's intention to use the results of these Company-sponsored clinical
trials along with the results of the clinical trials conducted at TJU, as the
basis for the filing of an application for FDA approval to market M-Vax. During
the third and fourth quarters of 1997 the Company designed and developed a class
10,000 clean room at TJU to be used as interim capacity which the Company
believes is adequate to support commencement of the Phase III clinical program.
Completion of these studies, however, is dependent upon the Company's ability to
establish additional Good Manufacturing Practice ("cGMP") facilities which will
be needed for compliance with certain regulatory standards promulgated by the
FDA. To that end, the Company has entered into a lease for space in
Philadelphia, Pennsylvania to begin construction of such a facility. While
management of the Company anticipates that such additional facilities will be
established in a timely manner, there can be no assurance of the adequacy of the
manufacturing or of FDA acceptance. Delays in either manufacturing capability or
regulatory approval would delay completion of these studies and could have a
material adverse effect on the Company. Depending upon the results of the
anticipated clinical trials, the Company intends 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 an application for FDA approval
to market M-Vax. The Company's management estimates that it may be in the
position to submit such application for FDA approval in approximately the year
2000 or 2001. The targeted timetable for filing a marketing application depends
upon the rate of enrollment of both clinical sites and patients in the Phase III
studies, the adequacy of the overall clinical outcome data from these trials,
and ultimately acceptance by the FDA of the studies. A delay in enrollment of
either clinical sites or patients would delay completion of the trials.
Moreover, equivocal clinical outcomes from such trials would have the effect of
at least delaying the timetable for submission of a marketing application and
would impact negatively on regulatory acceptance of the studies in connection
with the possible approval of such marketing application.

The Company also may pursue a similar regulatory approval and commercialization
strategy for M-Vax in Australia, Canada, Mexico and certain other countries
through corporate partnering strategies, although such strategies have not yet
been finalized or initiated. Denial of any regulatory approvals or any
significant delays in obtaining any of the same, would have a material adverse
effect on the Company.

The Company is treating post-surgical stage 3 patients in its Phase I/II
clinical trial of O-Vax, its AC Vaccine for ovarian cancer. This trial is being
conducted at TJU under the direction of Dr. Berd and has already shown a
positive immune response, as measured by a DTH test, in the first seven of seven
patients. The Company intends for further clinical trials to be conducted for
the purpose of collecting Phase I/II preliminary efficacy data with respect to
the effectiveness of O-Vax in treating advanced stages of ovarian cancer, and to
use the results of all such Company-sponsored trials to support the commencement
of a subsequent Phase III program for O-Vax.

The Company also plans to initiate a similar Phase I/II clinical trial of
C-Vax(TM), its AC Vaccine for colorectal cancer, during 1998.

There can be no assurance, however, that the foregoing forward-looking
statements with respect to the Company's intended timetable for the commencement
of the Phase III clinical trials for M-Vax, the eventual filing of a marketing
application for M-Vax and the Company's intended timetable for clinical trials
for O-Vax and C-Vax will be met. For a discussion of certain of the risks and
uncertainties which may impact upon such timing, see "Risk Factors--Development
Stage Company", "Technological Uncertainty and Early Stage of Product
Development", "Government Regulation; No Assurance of Product Approval",
"Dependence on Others for Clinical Development of, and Regulatory Approvals for,
Manufacturing and Marketing of Pharmaceutical Products", "Dependence on Licenses
and Sponsored Research Agreements", "Lack of Manufacturing Facilities", "Forward
Looking Statements" and the other items under "Risk Factors".

In addition, the Company has recently entered into a Technical Testing Agreement
(the "Illinois Agreement") with the University of Illinois ("Illinois"),
pursuant to which Illinois will conduct testing in order to determine whether an
animal model can be used to demonstrate the therapeutic potential of
DNP-vaccine, such as the Company's AC Vaccine, in experimental tumor models, and
the value of adjunctive therapies. In consideration of the Illinois Agreement,
the Company and Illinois have agreed to a budget of approximately $160,000 for
the expected two-year term of the study, which shall be funded by the Company.

    TOPOISOMERASE INHIBITORS

The Rutgers License relates to a series of novel anticancer compounds being
prepared and studied under the direction of Professors Edmund LaVoie and Leroy
Liu at Rutgers University (the "Rutgers Compounds"). The Rutgers Compounds have
proven effective on animal models during preclinical studies, and, although
there can be no assurance, the Company believes that they may be effective on
humans. The Rutgers Compounds fall into six distinct and varied chemical
classes, and have been shown to inhibit topoisomerase I or topoisomerase II
activities, depending on the exact structure. Topoisomerases are key enzymes
needed for remolding DNA, a necessary function for malignant tumor growth.
Inhibitors of these enzymes have been proven to be clinically-useful anticancer
therapies. In addition to having topoisomerase-inhibiting characteristics, some
of the Rutgers compounds have shown activity against fungal as well as parasitic
organisms. Both United States and non-U.S. patents have been filed for the
Rutgers Compounds and their anticancer and anti-infective uses. Although such
compounds are in an early stage of preclinical development for solid tumor,
antifungal and parasitic indications, the Company intends to pursue development
of one or more of these compounds. The Company's management anticipates that the
preclinical work may lead to indentification of a lead compound by early 1998,
and that an IND for such compound may be filed with the FDA during 1998, or
early 1999. However, there can be no assurance that any such compounds will
ultimately reach a stage of clinical testing or commercialization. For a
discussion of certain risks which may impact upon the timing and outcomes of the
development of the Rutgers compounds, see "Risk Factors--Development Stage
Company", "Technological Uncertainty and Early Stage of Product Development",
"Government Regulation; No Assurance of Product Approval", "Dependence on Others
for Clinical Development of, and Regulatory Approvals for, Manufacturing and
Marketing of Pharmaceutical Products", "Dependence on Licenses and Sponsored
Research Agreements", "Lack of Manufacturing Facilities", "Forward Looking
Statements" and the other items under "Risk Factors".

    NOVEL ANTI-ESTROGENS

The Texas A&M License relates to a series of novel anticancer compounds (the
"Texas A&M Compounds") being prepared and studied under the direction of
Professor Stephen Safe at Texas A&M University. The unique activity against


                                       29
<PAGE>


solid tumors exhibited by the Texas A&M Compounds can be classified as
anti-estrogen, although they appear to act indirectly on the estrogen receptor
through a novel pathway. Anti-estrogens have been proven to be clinically-useful
anticancer therapies. United States patents for both the Texas A&M Compounds and
their anticancer uses have been filed. Although non-U.S. patent filings have not
yet been made, the Company expects that foreign patent coverage will be pursued
as the result of ongoing laboratory research. Although such compounds are in a
early stage of preclinical development for solid tumor indications, the Company
intends to pursue development of one or more of these compounds. The Company's
management anticipates that the preclinical work may lead to indentification of
a lead compound early 1998, and that an IND for such compound may be filed with
the FDA during 1998, or early 1999. However, there can be no assurance that any
such compounds will ultimately reach a stage of clinical testing or
commercialization. For a discussion of certain risks which may impact upon the
timing and outcomes of the development of the Texas A&M compounds, see "Risk
Factors--Development Stage Company", "Technological Uncertainty and Early Stage
of Product Development", "Government Regulation; No Assurance of Product
Approval", "Dependence on Others for Clinical Development of, and Regulatory
Approvals for, Manufacturing and Marketing of Pharmaceutical Products",

Manufacturing Facilities", "Forward Looking Statements" and the other items

RESEARCH AND DEVELOPMENT

         AUTOLOGOUS CELL VACCINES

In connection with the TJU License entered into in November 1995, TJU, Dr. Berd,
as TJU's principal investigator, and the Company entered into a Clinical Study
and Research Agreement pursuant to which TJU and Dr. Berd began a research and
clinical study program for the further development of the AC Vaccine technology
for additional cancer targets. In turn, the Company agreed to fund such research
as follows: $220,094 for the first year of the agreement, $220,381 for the
second year of the agreement and at least $100,000 for the third year of the
agreement. Following the third year, the Company is obligated to spend a minimum
of $500,000 per year on the development of the AC Vaccine technology until
commercialized in the United States. If following the third year, the Company
files for FDA approval of a Company-sponsored marketing application 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 marketing application is under review
by the FDA. If the Company does not meet its financial, development, or other
obligations in a timely manner under its license agreements or related sponsored
research agreements, the Company could lose the rights to its proprietary
technology or the right to have its licensors and others conduct its research
and development efforts, any of which could have a material adverse effect on
the Company. TJU has the right to terminate the R&D agreement on 30 days'
written notice if it becomes unable for any reason to complete the Study.
See "Risk Factors--Dependence on Licenses and Sponsored Research Agreements."

         TOPOISOMERASE INHIBITORS

In consideration of the license granted to the Company by Rutgers in December
1996, the Company has committed to the funding of research for each of the first
three years of the Rutgers License at a rate of $100,000 per year as well as the
payment of certain indirect overhead costs. The Company also is obligated to pay
Rutgers for certain overhead costs for such three-year period on a deferred
basis. In addition, the Company is obligated to spend an aggregate of $200,000
in the first year, $300,000 in the second year and $500,000 each year thereafter
until the first year of commercial marketing of a product derived from the
Rutgers compounds, for the development, research (including the $100,000
research funding commitment in each of the first three years), manufacture,
regulatory approval, marketing and selling of a product derived from the Rutgers
compounds. If the Company fails to make such payments in accordance with the
terms of the Rutgers License, Rutgers would be entitled to terminate the
agreement and no further research would be performed thereunder. The termination
of the Rutgers License could have a material adverse effect on the Company. See
"Risk Factors--Dependence on Licenses and Sponsored Research Agreements."

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

         NOVEL ANTI-ESTROGENS

In consideration of the license granted to the Company by Texas A&M in February
1997, the Company has committed to the funding of research in the amount of
$108,750 for each of the first three years. In addition, the Company is required
to achieve certain milestones toward development of a licensed product within
certain specified time frames. If the Company fails to make such payments or
achieve such milestones in accordance with the terms of the Texas A&M License,
Texas A&M would be entitled to terminate the agreement and no further research
would be performed thereunder. The termination of the Texas A&M License could
have a material adverse effect on the Company. See "Risk Factors--Dependence on
Licenses and Sponsored Research Agreements."

It is anticipated that the research and development effort with respect to the
potential anti-cancer compounds licensed under the Texas A&M License will be
conducted at Texas A&M under the direction of Stephen H. Safe, Ph.D., the
originator of the technology underlying the Texas A&M License. Dr. Safe is Sid
Kyle Professor of Toxicology at Texas A&M and is a member of the Company's
Scientific Advisory Board. See "Management--Scientific Advisory Board."

PROPRIETARY RIGHTS

         THE TJU LICENSE

Pursuant to the TJU License, the Company has licensed an issued U.S. patent and
certain U.S. and foreign patent applications covering a process for the
modification of a patient's own tumor cells into a cancer vaccine. The TJU
License is a royalty-bearing license for the rights to such patented vaccine
technology, and provides for certain payments upon the occurrence of certain
milestones. As consideration for the TJU License, the Company paid $10,000 to
TJU, and issued 229,121.5 shares of Common Stock to each of TJU and Dr. Berd,
representing 7.5% (15% in the aggregate) of the Company's total outstanding
voting securities at the time of issuance.

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

         THE RUTGERS LICENSE

Pursuant to the Rutgers License, the Company has licensed certain U.S. and
foreign patent applications relating to a series of compounds for the potential
treatment of cancer and infectious diseases. The Company paid $15,000 as
consideration for the Rutgers License, and has agreed to pay an additional
$15,000 license maintenance fee in each subsequent year. The Company has also
committed to the issuance to Rutgers of warrants to purchase 125,000 shares of
Common Stock at a price of $8.24 per share. Such warrants are exercisable upon
the achievement of certain development-related milestones. The first 75,000 of
such warrants will expire in 2006 and the final 50,000 of such warrants will
expire in 2011. These warrants will provide for cashless exercise, piggyback
registration rights and certain anti-dilution rights.

The Company also has agreed to fund research in the amount of $100,000 per year
for the first three years of the Rutgers License as well as to pay for certain
indirect overhead costs during such time. The Company also is obligated to pay
on a deferred basis for certain overhead costs for such three-year period. The
license maintenance fee is not payable in years where research funding is equal
to or greater than $100,000.

The Company is also obligated to pay certain milestone payments as follows:
$15,000 on the earlier of October 31, 1999 or the date of first filing of an IND
application with the FDA, or comparable international agency, $25,000 on the
earlier of October 31, 2001 or the date of initiation of Phase II trials in the
United States or another major market country, $45,000



                                       31
<PAGE>


on the earlier of October 31, 2005 or the date of first filing of a marketing
application with the FDA, or comparable international agency and $150,000 on the
earlier of October 31, 2008 or the date of receipt by the Company of approval
from the FDA or comparable international agency to market products. In addition,
the Company is required to pay royalties on its worldwide net sales revenue
derived from the Rutgers compounds and a percentage of all revenues received
from sublicenses of products derived from these compounds. Failure to comply
with the terms of the Rutgers License may cause its termination, which would
have a material adverse effect on the Company. See "Risk Factors--Dependence on
Licenses and Sponsored Research Agreements."

         THE TEXAS A&M LICENSE

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

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

COMPETITION

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

Many of the companies engaged in anticancer research and development and in
acquiring rights to the products of such research and development, including
biotechnology companies, have substantially greater financial, technical,
scientific, manufacturing, marketing and other resources than the Company and
have more experience in developing, marketing and manufacturing therapeutics,
including performing the preclinical testing and clinical trials that are
required for obtaining FDA and other regulatory approvals. Included among the
Company's competitors are: (i) large established pharmaceutical and
biotechnology companies with commitments to oncology or antiviral research,
development and marketing, including, without limitation, Schering Plough
Corporation, Chiron Corporation, Bristol-Myers Squibb and Johnson & Johnson;
(ii) smaller biotechnology companies with similar strategies, including IDEC
Pharmaceuticals, Inc. and Biomira Diagnostics; 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.

A number of companies or research institutions are developing cancer vaccines,
including, without limitation, Ribi ImmunoChem Research, Inc. and Progenics,
Inc., in melanoma; AltaRex, Genentech and Biomira, in ovarian cancer; and
PerImmune, Inc. and Aphton Corporation, in colorectal cancer. 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 in


                                       32
<PAGE>


melanoma. Although there can be no assurance, the Company also believes that its
AC Vaccine technology may be applicable to a variety of solid tumors such as
ovarian, breast, prostate, lung and colorectal cancer and may have applications
in the treatment of acute myelogenous leukemia (AML) and therefore may not be as
limited as certain other approaches. With respect to the timing of the entry of
the product, there can be no assurance as to when, if at all, any of the
Company's potential products will be approved. See "Risk Factors--Technological
Uncertainty and Early Stage of Product Development", "Government Regulation; No
Assurance of Product Approval", "Dependence on Others For Clinical Development
of, and Regulatory Approvals for, Manufacturing and Marketing of Pharmaceutical
Products", "Dependence on Licenses and Sponsored Research Agreements",
"Dependence Upon Key Personnel and Consultants" and "Lack of Manufacturing
Facilities".

MANUFACTURING AND MARKETING

The Company does not currently have the resources to commercially 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, commercial manufacturing and/or marketing of its products if such
activities are commercially feasible. These partners may also be responsible for
commercial scale manufacturing, which will be subject to compliance with
applicable FDA regulations. The Company anticipates that such arrangements may
involve the grant of exclusive or semi-exclusive rights to sell specific
products to specified market segments or particular geographic territories in
exchange for a royalty, joint venture, future co-marketing or other financial
interests.

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

The Company may elect to establish its own commercial manufacturing facilities
for the products and technologies that it may develop. In the event the Company
decides to establish manufacturing facilities, the Company will be required to
hire and train significant numbers of employees and to comply with the extensive
cGMP regulations applicable to such a facility. The establishment of any such
facilities and eventual expansion of operations to commercial levels, as well as
the hiring of qualified employees, could require substantial expenditures. In
addition, at least some of the Company's products produced at its facilities
will probably be regulated as biologics. In that event, the Company would be
required to file with the FDA in order to obtain an establishment license (or
similar license) for its facilities. Legislation that would eliminate the
requirement for an establishment license is currently pending before Congress,
but there is no assurance that this legislation will be enacted. Any delay in
the FDA's approval of (or its refusal to grant) such a license would delay or
prevent marketing of the relevant product. See "Risk Factors--Lack of
Manufacturing Facilities" "--Dependence on Others for Clinical Development of,
and Regulatory Approvals for Manufacturing and Marketing of Pharmaceutical
Products."

GOVERNMENT REGULATION

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

Generally, the steps required before a pharmaceutical or therapeutic biological
agent may be marketed in the United States include: (i) preclinical laboratory
tests, IN VIVO preclinical studies in animals, toxicity studies and formulation
studies; (ii)


                                       33
<PAGE>

the submission to the FDA of an IND application for human clinical testing, that
must become effective before human clinical trials commence; (iii) adequate and
well-controlled human clinical trials to establish the safety and efficacy of
the drug; (iv) the submission of a marketing application to the FDA; and (v) FDA
approval of the marketing application prior to any commercial sale or shipment
of the drug.

Preclinical studies include laboratory evaluation of the product, conducted
under Good Laboratory Practice (GLP) regulations, and animal studies to assess
the pharmacological activity and the potential safety and effectiveness of the
drug. The results of the preclinical studies are submitted to the FDA in the
IND. Unless the FDA objects to an IND, it becomes effective 30 days following
submission and the clinical trial described in the IND may then begin.

Every clinical trial must be conducted under the review and oversight of an
institutional review board (IRB) at each institution participating in the trial.
The IRB evaluates, among other things, ethical factors, the safety of human
subjects, and the possible liability of the institution.

Clinical trials are typically conducted in three sequential phases, although the
phases may overlap. Phase I represents the initial introduction of the drug to a
small group of healthy subjects to test for safety, dosage tolerance, and the
essential characteristics of the drug. Phase II involves studies in a limited
number of patients to test the safety and efficacy of the drug at different
dosages. Phase III trials involve large-scale evaluation of safety and
effectiveness, usually (though not necessarily) in comparison with placebo or an
existing treatment.

The results of the preclinical and clinical trials are submitted to the FDA as
part of an application to market the drug. The marketing application also
includes information pertaining to the chemistry, formulation, manufacture of
the drug and each component of the final product. The FDA review of a marketing
application takes from one to two years on average to complete, though reviews
of treatments for cancer and other life-threatening diseases may be accelerated.
However, the process may take substantially longer if the FDA has questions or
concerns about a product. Following review, the FDA may ultimately decide that
an application does not satisfy regulatory and statutory criteria for approval.
In some cases, the FDA may approve a product but require additional clinical
tests following approval (i.e., Phase IV).

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 inspections by the FDA and
must comply with Good Manufacturing Practice ("GMP"). To supply products for use
in the United States, foreign manufacturing establishments must comply with GMP
and are subject to periodic inspection by the FDA or by corresponding regulatory
agencies in such countries under reciprocal agreements with the FDA. As
permitted by FDA regulations, the M-Vax and O-Vax phase I/II human clinical
trials are being conducted by TJU under the supervision of Dr. David Berd
pursuant to an FDA-approved physician sponsored IND. Following an earlier
meeting with the FDA to discuss the clinical results obtained with M-Vax, the
use of such results in support of the submission of a Company-sponsored IND to
the FDA, and to review its proposed development plan, the Company reviewed a
proposed phase III protocol with FDA and plans to submit a Company-sponsored IND
to support the pivotal trial program. This IND will also address product
characterization/manufacturing issues raised by FDA to ensure that all pivotal
data will support a product license application. No patients will be enrolled in
the pivotal trial program until the Company and FDA are satisfied that all
product issues are resolved. Depending upon the results of such clinical trials,
it is the Company's intention to use the results of these Company-sponsored
clinical trials along with the results of the clinical trial conducted at TJU,
as the basis for the filing of an application for FDA approval to market M-Vax.
Even if the Company eventually receives FDA approval of a marketing application
to commercialize any of its products, there can be no assurance that the Company
will be able to successfully manufacture such product at a commercially
acceptable cost.

If marketing approval of any Company product is granted, the Company must
continue to comply with FDA requirements not only for manufacturing, but also
for labeling, advertising, record keeping, and reporting to the FDA of adverse
experiences and other information. In addition, the Company must comply with
federal and state health care antikickback laws and other health care fraud and
abuse laws that affect the marketing of pharmaceuticals. Failure to comply with
applicable laws and regulations could subject the Company to administrative or
judicial enforcement actions, including but not limited to product seizures,
injunctions, civil penalties, criminal prosecution, refusals to


                                       34
<PAGE>

approve new products or withdrawal of existing approvals, as well as increased
product liability exposure, any of which could have a material adverse effect on
tile company's business, financial condition, or results of operations.

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 ("EU").
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 EU certain registration procedures
are available to companies wishing to market their products in more than one EU
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 EU
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 EU. Other products will be registered by
national authorities in individual EU member states, operating on a principle of
mutual recognition. This foreign regulatory approval process includes, at least,
all of the risks associated with FDA approval set forth above. The Company could
possibly have greater difficulty in obtaining any such approvals and also might
find it more difficult to protect its intellectual property abroad.

SOURCES AND AVAILABILITY OF RAW MATERIALS

The Company does not expect to encounter significant difficulties in obtaining
raw materials for M-Vax, O-Vax or C-Vax, since they are primarily composed of a
readily available chemical reagent, DNP, and the patient's own tumor cells.
Should the supply of DNP significantly decrease, the Company may encounter
problems preparing M-Vax, O-Vax, C-Vax, or any other AC Vaccine technology.

COMPLIANCE WITH ENVIRONMENTAL LAWS

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

EMPLOYEES

The Company utilizes a product development strategy that includes contracting
out its research and development, and to a certain extent, some other functions
in order to minimize the expenses and overhead associated with full-time
employees. Consistent with this strategy, as of March 3, 1998, the Company had
six full-time employees, including Jeffrey M. Jonas, M.D., its President and
Chief Executive Officer, David L. Tousley, C.P.A., its Chief Financial Officer,
and Ernest W. Yankee, Ph.D., its Executive Vice President. Its other
consultants, scientific advisors, part-time officers and directors devote only a
portion of their time to the business of the Company. The Company believes that
it maintains good relations with 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. In October of 1996, the Company entered into a three-year
lease for approximately 2,800 square feet of office space with a monthly rental
of approximately $5,400, beginning in the fourth month. This lease was amended
in December 1997 to add approximately 1,300 additional square feet of office
space for the remainder of the original lease term which increased the monthly
rental by approximately $2,700.



                                       35
<PAGE>

The Company anticipates that in the future it may own or lease its own facility
for the manufacturing of its potential products and has entered into a 10-year
lease for approximately 11,900 square feet of space in Philadelphia,
Pennsylvania to begin construction of such a facility. The lease began in
February 1998, contains options for expansion in 1999 and 2002 and contains an
option to terminate at the end of the fifth year. The initial monthly rental is
approximately $10,400.

The research work of the Company is currently being conducted at TJU, Rutgers
and Texas A&M pursuant to their respective license and research agreements with
the Company. See "Risk Factors--Lack of Facilities," --"Dependence on Third
Parties for Additional Funds and for Manufacturing, Marketing and Selling," and
"--Dependence on Others for Clinical Development of, and Regulatory Approvals
for, and Manufacturing and Marketing of Pharmaceutical Products" and "Certain
Transactions."

LEGAL PROCEEDINGS

The Company's application for a federal trademark registration for the name AVAX
has been opposed by a third party. This opposition proceeding concerns the right
of the Company to obtain a federal trademark registration in the United States
Patent & Trademark Office for the name AVAX. Although the Company believes there
is a sound basis for denial of the opposition and allowance of its application
to register the name AVAX, there can be no assurance that the Company will
prevail in this proceeding. There is also no assurance that the Company will
desire or be able to continue using the name AVAX at some future time. The
Company does not believe that an adverse outcome in this proceeding will
materially affect its business.

The Company is not aware of any other pending or threatened legal actions which,
in the opinion of management, based on known information, is likely to have a
material adverse effect on the Company's business.

RESEARCH AND DEVELOPMENT EXPENSE

For fiscal years 1996 and 1997, the Company incurred research and development
expense of $738,991 and $2,448,976, respectively. Research and development
expense for the period from inception has been $4,801,285. See "Financial
Statements." Although there can be no assurance, the Company intends to spend
increasingly more on research and development in the foreseeable future.

SCIENTIFIC ADVISORY BOARD

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

David Berd, M.D. -- Chairman    Clinical Oncologist at the Jefferson Cancer
                                Center of TJU and Inventor of the Company's AC
                                Vaccine technology.
Edmond J. LaVoie, Ph.D.         Professor of Medicinal Chemistry and Chairman
                                of the Department of Pharmaceutical Chemistry
                                at Rutgers University.
Margalit Mokyr, Ph.D.           Professor of Biochemistry at the University of
                                Illinois College of Medicine.
Stephen H. Safe, Ph.D.          Sid Kyle Professor of Toxicology at Texas A&M
                                University.
Robert J. Belt, M.D.            Medical Director at the Peet Cancer Center of
                                Saint Luke's Hospital in Kansas City.

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

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

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

BOARD COMPENSATION

In September 1997, as compensation for services rendered and to be rendered as
members of the Company's Board of Directors, the Company issued to each of Mr.
de Castro, Dr. Spana, Dr. Prendergast and Mr. Weiss, options to purchase 40,000
shares of Common Stock, exercisable for seven years at an exercise price equal
to $4.50 per share. Such options shall vest at a rate of 1/16 per quarter for a
period of four years, commencing on December 1, 1997. The Company currently
intends to compensate its directors on an annual basis, at the election of each
such director (which election must be made annually by December 15th of the year
immediately prior to the year in which such compensation is earned (the
"Election Date")), as follows: (i) $ 10,000, payable quarterly in arrears (the
"Director's Fee"), or (ii) options to purchase that number of shares of Common
Stock in an amount equal to the result obtained by multiplying (A) two by (B)
the result obtained by dividing (x) the Director's Fee by (y) the closing price
of the Common Stock on the Election Date, or the last business day preceding the
Election Date (the "Closing Price"); which options shall vest at a rate of 1/4
per quarter over a one-year period and shall be exercisable for a period of
seven years at an exercise price equal to the Closing Price. All directors have
elected to be compensated for their 1998 services with options to purchase
common stock and accordingly, in December, 1997, were each issued options to
purchase 5,161 shares of Common Stock with the foregoing terms at an exercise
price of $3.875 per share of Common Stock. In the event of a change of control
(as defined in the applicable stock option agreements), each of the foregoing
outstanding stock options, generally, will immediately vest in full, either at
the time of such event, or upon the subsequent termination of such individual's
service with AVAX.

Dr. Jonas receives no compensation for service on the Board of Directors or any
committee thereof. All directors of the Company are reimbursed for travel
expenses incurred in attending board and committee meetings.

The Company may retain additional board members in the future. Certain of the
directors may have consulting agreements and/or received stock grants in
consideration for services rendered to the Company, other than services rendered
as members of the Board. See "Executive Compensation" and "Certain
Transactions."

EXECUTIVE COMPENSATION

The following Summary Compensation Table sets forth the compensation earned by
the persons serving as either the Company's chief executive officer and the
other named executive officers (collectively the "Named Officers") for the last
three fiscal years. No other executive officer earned compensation in excess of
$100,000 for services rendered to the Company for any such fiscal year and no
executive officer, who would have otherwise been included in such table,
resigned or terminated employment during that year. With respect to the persons
and periods covered in the following table, the Company made no restricted stock
awards and had no long-term incentive plan payouts.

                              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
$25,800,000. In connection with services rendered by Paramount Capital, Inc., as
placement agent ("Paramount" or the "Placement Agent"), for the Series B
Offering, and pursuant to a placement agency agreement entered into by the
Company and the Placement Agent, the Company paid the Placement Agent cash
commissions of approximately $2,324,000, a non-accountable expense allowance of
approximately $1,033,000 and placement warrants ("Series B Placement Warrants")
to acquire approximately 25,820 shares of Series B Preferred Stock, exercisable

Stock. See "Description of Securities."

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

On October 20, 1995, the Company entered into an Engagement & Technology
Acquisition Agreement with The Castle Group, LLC ("The Castle Group"), which may
be deemed an affiliate of both the Company and the Placement Agent, pursuant to
which The Castle Group identified, negotiated and acquired for the Company the
TJU License. In consideration for the conveyance of the license, TJU and Dr.
Berd were both granted 229,121.5 shares of Common Stock. In connection
therewith, The Castle Group and its designees were granted and sold 916,485.5
shares of Common Stock of the Company at a price of $.004 per share. Prior to
the acquisition of the TJU License, the Company had no technological assets
other than it's former lead product under development, which was sold in
December 1995.

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 personally collateralized loans to the
Company from NatWest Bank N.A., pursuant to which the Company incurred principal
and interest indebtedness of approximately $55,000. Such indebtedness was paid
in full as of June 30, 1996. Dr. Rosenwald also extended a line of credit to the
Company. As of June 30, 1996, the Company paid the outstanding principal amount
and accrued interest under such line of credit, which was approximately
$250,000. In addition, in 1995 and 1996, Paramount acted as placement agent,
pursuant to a placement agency agreement, for a bridge financing for the Company
as to which Paramount was paid $90,000 in commissions and received warrants to
purchase 31,250 shares of Common Stock. Two of the investors in these bridge
financings were private investment funds managed by a company for which Dr.
Rosenwald is President. Also, Michael S. Weiss, Director and Secretary of the
Company, is a Senior Managing Director of Paramount and General Counsel of
Paramount Capital Investments, LLC. Wayne Rubin, at that time the Treasurer of
the Company, is Chief Financial Officer of Paramount and Paramount Capital
Investments, LLC. Dr. Carl Spana, a Director of the Company, was at that time a
Vice President of Paramount Capital Investments, LLC. Dr. John K.A. Prendergast,
also a Director of the Company, is a Managing Director of Paramount Capital
Investments, LLC.

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

Pursuant to the Company's Certificate of Incorporation and bylaws, the Company
has agreed to indemnify the Directors and Officers of the Company to the maximum
extent permissible under Delaware law. Insofar as indemnification for
liabilities arising under the Securities Act of 1933 (the "Act") may be
permitted to directors, officers and controlling persons of the Company pursuant
to the foregoing, or otherwise, the Company has been advised that, in the
opinion of the Commission, such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable.

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 B PREFERRED STOCK

The Board of Directors of the Company has authorized the issuance of up to
300,000, of which 196,677 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 initially was convertible, in whole or
part, at the option of the holder at any time after the initial issuance date
into 25 shares of Common Stock based upon an initial conversion price of $4.00
per share of Common Stock (the "Initial Conversion Price"). As of June 11, 1997,
13,250 shares of Series B Preferred Stock had been converted into shares of
Common Stock. The Initial Conversion Price was adjusted effective June 11, 1997
(the "Reset Date"), because the average closing bid price of the Common Stock
for the 30 consecutive trading days immediately preceding such date was less
than $5.40. The average was, in fact, $5.175 per share. Accordingly, the
conversion price was adjusted to $3.83 per share, which corresponds to a new
conversion rate of 26.0875 shares of Common Stock per share of Series B
Preferred Stock. The conversion price is subject to further adjustment upon the
occurrence of certain mergers, reorganizations, consolidations,
reclassifications, stock dividends or stock splits which will result in an
increase or decrease in the number of shares of Common Stock outstanding.

         MANDATORY CONVERSION

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

         LIQUIDATION

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

         VOTING RIGHTS

The holders of the Series B Preferred Stock have the right at all meetings of
stockholders to the number of votes equal to the number of shares of Common
Stock issuable upon conversion of the Series B Preferred Stock at the record
date for determination of the stockholders entitled to vote. So long as 50% of
the shares of Series B Preferred Stock remain outstanding, the holders of 66.67%
of the Series B Preferred Stock are entitled to approve (i) the issuance of any
securities of the Company senior to or on parity with the Series B Preferred
Stock, (ii) any alteration or change in the rights or preferences or privileges
of the Series B Preferred Stock and (iii) the declaration or payment of any
dividend on any junior stock or the repurchase of any securities of the Company.
Except as provided above or as required by applicable law, the holders of the
Series B Preferred Stock will be entitled to vote together with the holders of
the Common Stock and not as a separate class.

LOCK-UP AGREEMENTS

The holders of shares of Common Stock issuable upon conversion of shares of
Series B Preferred Stock (the "Conversion Shares") agreed pursuant to their
subscription agreements with the Company not to offer, pledge, sell, contract to
sell, grant any option for the sale of, or otherwise dispose of, directly or
indirectly, 75% of the Conversion Shares, without the prior written consent of
the placement agent in the Series B Offering (the "Lock-Up"). Such restrictions
were effective as follows: (i) with respect to 75% of the Conversion Shares
until September 12, 1996 (three months after the completion of the Series B
Offering); with respect to the 50% of the Conversion Shares until December 12,
1996 (six months after the completion of the Series B Offering); and with
respect to the remaining 25% of the Conversion Shares until March 11,


                                       48
<PAGE>


1997 (nine months after the completion of the Series B Offering). Accordingly,
25% of each of the holders' Conversion Shares were never subject to the Lock-Up,
and as of March 11, 1997, the Lock-Ups expired.

However, holders of approximately 94% of the shares of Series B Preferred Stock
agreed to amend their subscription agreements with the Company to extend the
Lock-Up period. Pursuant to this amendment, the Lock-Up for such holders' shares
of Series B Preferred Stock has been extended for the period following the later
of the effectiveness under the Securities Act of 1933 (the "Act") of the
Registration Statement ("Effectiveness") and the listing of the Conversion
Shares on a national securities exchange or initial quotation on the Nasdaq
SmallCap Market ("Listing"), which occurred on July 10, 1997, as follows: (i)
three months following the later of Effectiveness and Listing with respect to
75% of the Conversion Shares; (ii) six months following the later of
Effectiveness and Listing with respect to 50% of the Conversion Shares and (iii)
nine months following the later of Effectiveness and Listing with respect to the
remaining 25% of the Conversion Shares. Accordingly, 25% of such holders'
Conversion Shares continue to have never been subject to the Lock-Up. The
Conversion Shares of holders that did not agree to amend their subscription
agreement are not subject to any Lock-Up.

In consideration of the agreement with the Company to extend the Lock-Up period
for their Conversion Shares, holders of shares of Series B Preferred Stock that
agreed to such extended Lock-Up have the right as of July 10, 1998 (i.e., one
year after the later of Effectiveness and Listing), to have the Company issue
such number of additional shares of Common Stock as shall be necessary to effect
the principles of the original reset provisions contained in the Certificate of
Designations for the Series B Preferred Stock taking into account any
adjustments which may have been previously made at the time of the Reset Date.
Accordingly, the Company will become obligated to issue additional shares of
Common Stock to such holders if the average closing bid price of the Common
Stock for the 30 consecutive trading days immediately preceding July 10, 1998 is
less than $5.175 per share.

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

In addition, in connection with the Company's application for listing and
quotation of the Common Stock on the Nasdaq SmallCap Market, pursuant to the
request of Nasdaq, the Company obtained from the officers and directors of the
Company, and certain employees of Paramount and its affiliates, agreements
locking-up all securities and derivative securities of the Company held by such
individuals for a period of two years through July 10, 1999. Such agreements may
be waived in whole or in part at the option of the Company.

1992 STOCK OPTION PLAN

A total of 437,500 shares of Common Stock has been reserved for issuance under
the Company's 1992 Stock Option Plan (the "AVAX Option Plan"). The AVAX Option
Plan was adopted by the Board of Directors in April 1992 and approved by
stockholders of the Company in April 1992. The AVAX Option Plan expires by its
own terms in 2002. It is anticipated that the Company will put forth a proposal
to increase the amount of shares issuable pursuant to the AVAX Option Plan to
2,000,000 shares of Common Stock at its 1998 Annual Meeting which is currently
scheduled for June 3, 1998.

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

The AVAX Option Plan requires that the exercise price of incentive stock options
granted to employees of the Company who at the time of the grant of such
incentive stock option own stock representing more than 10% of the voting power
of all classes of stock of the Company or any parent or subsidiary, must be at
least equal to 110% of the fair market value of such shares on the date of
grant. The AVAX Option Plan also requires that the exercise price of incentive
stock options granted to any other employee of the Company must be at least
equal to the fair market value of such shares on the date of grant, and that the
exercise price of nonqualified stock options granted by the Company must be
equal to 85% of the fair market value per share on the date of


                                       49
<PAGE>


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

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

Pursuant to the AVAX Option Plan, as of March 3, 1998, options to purchase
30,000 shares of Common Stock were outstanding and fully vested at a weighted
average price of $1.20 per share, and no options had been exercised.

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

OTHER OPTIONS

Pursuant to their letters of employment with the Company, Dr. Jonas, Mr. Tousley

1/12 per quarter over a three-year period.

In connection with his letter of employment, effective February 10, 1997, one
other employee of the Company has received share options to purchase 52,500

1997, to reward and incent such employee, the Company withdrew such share
options and replaced them with share options to acquire 90,000 shares of Common

REGISTRATION RIGHTS

(1)  Unless otherwise indicated, includes all shares of Common Stock issuable
     upon conversion of the Series B Preferred Stock at the reset conversion
     rate of $3.83 per share. See "Description of Securities--Series B Preferred
     Stock."

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

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

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

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

                        SHARES ELIGIBLE FOR FUTURE SALES

Upon completion of the Offering, the Company will have 12,750,749 shares of
Common Stock outstanding or issuable upon the conversion of the Series B
Preferred Stock, the exercise of all outstanding or issuable options and
warrants as of the date of this prospectus. As of March 3, 1998, 4,777,488
shares of Common Stock were issued and outstanding, of which the Company
believes that, other than those shares registered in this offering, only
1,487,822 shares of Common Stock are "restricted securities" and under certain
circumstances may, in the future, be sold in compliance with Rule 144 under the
Securities Act of 1933 (the "Act"), unless they are held by "affiliates" of the
Company as that term is used under the Act. In addition, the Company has issued
and outstanding, or issuable, warrants and options to purchase an aggregate of
2,793,351 shares of Common Stock (excluding 49,229 shares of Common Stock
underlying Series B Placement Warrants and Bridge Placement Warrants that are
being registered in this Offering) and 5,130,681 shares of Common Stock that are
issuable upon conversion of shares of Series B Preferred Stock. Also, as of
March 3, 1998, the Company believes that there are approximately 3,289,666
outstanding shares of Common Stock that are eligible for sale without
restriction or further registration under the Act, subject to certain
requirements. See "Risk Factors--Potential Adverse Effect of Shares Eligible For
Future Sales" and "Description of Securities".

SALES OF RESTRICTED SHARES

As of March 3, 1998, 4,777,488 shares of Common Stock were issued and
outstanding, of which the Company believes that, other than those shares
registered in this offering, only 1,487,822 shares of Common Stock are
"restricted securities" and under certain circumstances may, in the future, be
sold in compliance with Rule 144 under the Act, unless they are held by
"affiliates" of the Company as that term is used under the Act. In general,
under Rule 144 as currently in effect, subject to the satisfaction of certain
conditions and certain manner of sale and notice requirements, including the
requirement that there is adequate current public information with respect to
the Company as contemplated by Rule 144, a person (or persons whose shares are
aggregated), including persons who may be deemed an affiliate of the Company as
that term is defined under the Act, who beneficially owned restricted shares of
Common Stock for at least one year is entitled to sell, within any three-month
period, a number of shares that does not exceed (i) the greater of one percent
of the total number of outstanding shares of the same class, or (ii) the average
weekly trading volume during the four calendar weeks immediately preceding the
sale. A person who presently is not and who has not been an affiliate of the
Company for at least three months immediately preceding the sale and who has
beneficially owned the shares of Common Stock for at least two years is entitled
to sell such shares under Rule 144(k) without regard to the volume limitations
described above. Certain shares eligible for sale under Rule 144 remain subject
to certain lock-up restrictions. See "Lock-Up Agreements."

No predictions can be made of the effect, if any, that the sale or availability
for sale of restricted shares or locked-up shares will have on the market price
of the Common Stock on the Nasdaq SmallCap Market. 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 6,355,248 shares of Common Stock are being directly offered for sale
by the Selling Securityholders to the public. The Selling Securityholders may,
but are not required to, sell, directly or through brokers, the shares of Common
Stock in negotiated transactions or in one or more transactions in the market at
the price prevailing at the time of sale. (Certain of the shares of Common Stock
may be subject to lock-up agreements. See "Description of Securities--Lock-Up
Agreements"). In connection with such sales, the Selling Securityholders and any
participating broker may be deemed to be "underwriters" of the shares of Common
Stock within the meaning of the 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 Act.

The Company will bear all costs and expenses of the registration under the 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 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 Act. It is anticipated that usual
and customary brokerage fees will be paid by the Selling Securityholders in all
open market transactions. The Company will pay all other expenses of this
Offering.

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

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

Certain Selling Securityholders may from time to time purchase shares of Common
Stock in the open market. These Selling Securityholders have been notified that
they should not commence any distribution of Common Stock unless they have
terminated their purchasing and bidding for Common Stock in the open market as
provided in applicable securities regulations, including, without limitation,
Regulation M.

                         Report of Independent Auditors

The Board of Directors and Stockholders
AVAX Technologies, Inc.

We have audited the accompanying balance sheet of AVAX Technologies, Inc. (a
development stage company) as of December 31, 1997, and the related statements
of operations, stockholders' equity (deficit) and cash flows for the years ended
December 31, 1996 and 1997, and for the period from January 12, 1990
(incorporation) to December 31, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of AVAX Technologies, Inc. at
December 31, 1997 and the results of its operations and its cash flows for the
years ended December 31, 1996 and 1997, and for the period from January 12, 1990
(incorporation) to December 31, 1997, in conformity with generally accepted
accounting principles.

1. DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

DESCRIPTION OF BUSINESS

AVAX Technologies, Inc. (the Company) is a development stage biopharmaceutical
company.

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

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

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

In February 1997, the Company entered into a license agreement with Texas A&M to
develop, commercially manufacture and sell products embodying a series of
compounds for the treatment of cancer (the Texas A&M Compounds) (see NOTE 3).

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

                    Notes to Financial Statements (continued)

1. DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

USE OF ESTIMATES

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

CASH EQUIVALENTS

The Company considers all highly liquid financial instruments with a maturity of
three months or less when purchased to be cash equivalents. At December 31,
1997, all cash and cash equivalents were held at two financial institutions.

MARKETABLE SECURITIES

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

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

DEFERRED COMPENSATION

Certain compensation costs are deferred and amortized over the vesting period of
such compensation.

SHARE INFORMATION

Prior to the first closing of a private placement on May 15, 1996 (see NOTE 4),
the Company effected a 1-for-2 reverse stock split of the Company's common
stock. Pursuant to an amendment to the Company's Certificate of Incorporation
dated May 7, 1997, a second 1-for-2 reverse split of the Company's common stock
was effected as of the close of business on May 13, 1997. All outstanding share
and per share amounts included in the accompanying financial statements have
been adjusted to reflect both 1-for-2 reverse stock splits.

EARNINGS PER SHARE

In 1997, the Financial Accounting Standards Board (FASB) issued Statement of
Financial Accounting Standards (SFAS) No. 128, "Earnings Per Share." SFAS No.
128 replaced the calculation of primary and fully diluted earnings per share
with basic and diluted earnings per share. Unlike primary earnings per share,
basic earnings per share exclude any dilutive effects of options, warrants and
convertible securities. Diluted earnings per share is very similar to the
previously required fully diluted earnings per share. All earnings per share
amounts for all periods have been presented, and where appropriate, restated to
conform to the SFAS No. 128 requirements.

Net loss per share is based on net loss divided by weighted average number of
shares of common stock outstanding during the respective periods, adjusted to
reflect the reverse stock splits. The weighted average number of common shares
outstanding has been calculated in accordance with Staff Accounting Bulletin 83
(SAB 83) of the Securities


                                      F-11

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 loss per
share, the private placement of Series B convertible preferred stock (see NOTE
4) has been considered to be the equivalent of an initial filing of a
registration statement relating to an initial public offering, and the initial
public offering price was determined to be $3.92 per share by assuming that the
preferred stock issued was immediately converted into common stock. Those shares
of common stock, warrants and options (see NOTE 4), considered as cheap stock in
accordance with SAB 83, were considered outstanding for all periods, prior to
July 10, 1997, at which time the Company's registration statement on Form SB-2
to register the shares sold in the private placement was declared effective.

The following table sets forth the computation of the Company's basic earnings
per share information, adjusted for the SAB 83 requirements, as discussed above.
Diluted earnings per share information is not presented, as the effects of stock
options, warrants and other convertible securities would be antidilutive for the
periods presented.

STOCK-BASED COMPENSATION

In October 1995, the FASB issued SFAS No. 123, "Accounting for Stock-Based
Compensation." SFAS No. 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 No. 123
requires compensation expense to be recorded (i) using the new fair value method
or (ii) using existing accounting rules prescribed by Accounting Principles
Board Opinion No. 25, "Accounting for Stock Issued to Employees," (APB 25) and
related interpretations, with pro forma disclosure of what net income and
earnings per share would have been had the Company adopted the new fair value
method. The Company has elected to continue to account for its stock-based
compensation plans in accordance with the provisions of APB 25. See NOTE 4 for
the pro forma effects of applying SFAS No. 123.

2. SALE OF THE PRODUCT

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

The first installment was paid on January 3, 1997 in the form of a distribution
of IPI stock directly by IPI to the Series A convertible preferred stockholders,
who were holders of record on the closing date of the agreement for sale, and
the Company's former President and Chief Executive Officer (the Former Officer).
The final installment was received on January 14, 1998. Accordingly, the common
stock receivable and the payables to preferred stockholders and the Former
Officer related to this installment are reported as current assets and
liabilities, respectively, in the accompanying balance sheet.

                    Notes to Financial Statements (continued)

2. SALE OF THE PRODUCT (CONTINUED)

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

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

     o   The remaining 4.15% of the Stock (or a cash payment equal to the value
         thereof) will be distributed to the Former Officer in partial
         consideration for his resignation from the Company and the return to
         the Company of all common stock of the Company and cancellation of
         options to purchase 62,500 shares of common stock (see NOTE 8).

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

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

other than the Stock to be received. The present value of the amount payable to
the preferred stockholders, including accretion of interest thereon, is
$1,150,200 at December 31, 1997, after being reduced by the payment of the first
installment in January 1997.

The discounted net present value of the Stock distributable to the Former
Officer as of the date of sale, amounting to $80,967, was allocated between
common stock ($445) and severance expense ($80,522) based on the fair value of
the Company's common stock ($.004 per share). The present value of the amount
payable to the Former Officer, including the accretion of interest thereon, is
$49,800 at December 31, 1997.

3. LICENSE AND RESEARCH AGREEMENTS

In November 1995, the Company entered into an agreement with TJU for the
exclusive worldwide license to develop, manufacture and sell the Invention. In
consideration for the license agreement, the Company paid cash of $10,000 and
issued an aggregate of 458,243 shares of common stock to TJU and the scientific
founder (the Scientist). These shares had antidilution rights prior to the first
equity financing, as defined in the license agreement, in excess of $1,000,000
by the Company.

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

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

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

In December 1996, the Company entered into an agreement with Rutgers for the
exclusive worldwide license to develop, manufacture and sell products embodying
the Compounds. In consideration for the license agreement, the Company paid cash
of $15,000, has agreed to pay $15,000 in each subsequent year as a license
maintenance fee and has committed to the issuance of warrants to Rutgers to
purchase 125,000 shares of common stock at a price of $8.24 per share based on
the achievement of certain development milestones. The first 75,000 warrants
will expire in 2006, and the final 50,000 warrants will expire in 2011. These
warrants, once issued, shall provide for cashless exercise, piggyback
registration rights and certain antidilution rights. The Company has agreed to
fund research in the amount of one hundred thousand dollars ($100,000) per year
for the next three years. In addition, the Company is obligated to spend an
aggregate of $200,000 in the first year, $300,000 in the second year and
$500,000 each year thereafter until the first year of commercial marketing of a
product derived from the Compounds. The license maintenance fee shall not be
payable in years where research funding is equal to or greater than $100,000.

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

3. LICENSE AND RESEARCH AGREEMENTS (CONTINUED)

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

In February 1997, the Company entered into an agreement with Texas A&M for the
exclusive worldwide license to develop, manufacture and sell products embodying
the Texas A&M Compounds. Under the terms of the license agreement, the Company
has agreed to fund research in the amount of approximately $108,000 per year for
the next three years. The Company is also obligated to pay certain milestone
payments as follows: $24,000 upon initiation of certain toxicity evaluations;
$12,000 upon completion of toxicity evaluations demonstrating certain acceptable
toxicity levels; $12,000 upon the submission of an IND to the FDA, or comparable
international agency; $5,000 upon completion of the first Phase I clinical
investigation; and $15,000 upon receipt by the Company of NDA approval from the

payments shall be no less than $50,000 in the first year of commercial
marketing, $100,000 in the second year, and $200,000 in the third year and all
following years.

4. EQUITY TRANSACTIONS

COMMON AND PREFERRED STOCK

Common stock issued for services since 1990 has been recorded based on the value
of the services provided.

In April 1995, in accordance with the terms of his resignation and related
severance arrangements, the Former Officer returned 111,330 shares of common
stock and options to purchase 62,500 shares of common stock. The common stock
returned was valued at $.004 per share. The common stock and options returned
were canceled.

4. EQUITY TRANSACTIONS (CONTINUED)

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

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

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

On March 24, 1996, the Company repurchased 77,901 shares of common stock
previously issued to an officer at $.004 per share. The repurchased shares were
canceled.

In May 1996, the Company's authorized capital was increased to 50,000,000 shares
of common stock, par value $.004, and 5,000,000 shares (of which 2,500,000
shares were designated as Series A preferred stock and 300,000 shares were
designated as Series B preferred stock) of preferred stock, par value $.01.

Pursuant to a private placement in May and June 1996, the Company issued
258,198 shares of Series B convertible preferred stock. The preferred
stockholders also received 129,099 shares of common stock. The total
consideration was $25,819,800. The per share price allocated to common stock and
Series B convertible preferred stock was $1 and $99, respectively. In connection
with the private placement, the Company paid $3,357,000 in commissions and
nonaccountable expenses to the placement agent, a related party, and issued 500
shares of common stock and 1,000 shares of Series B convertible preferred stock
as consideration for legal services valued at $100,000. In addition, the
placement agent received warrants to purchase 25,819.8 shares of Series B
convertible preferred stock at an exercise price of $110 per share. Such
warrants are exercisable until June 11, 2006, contain certain antidilution
provisions and may be exercised pursuant to a cashless exercise feature. Other
share issuance expenses amounted to $142,000.

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

Pursuant to the terms of the private placement, each share of Series B preferred
stock was convertible at any time, in whole or in part, at the discretion of the
holders, into common stock at $4 per share (the Initial Conversion Price), which
amounted to 6,479,950 shares at December 31, 1996. Twelve months after the final
closing date (the Reset Date), the Company could, at its option, cause
conversion of the preferred stock, in whole or in part, into common stock at the
Initial Conversion Price if the closing price of the common stock exceeded 150%
of the Initial Conversion Price for at least 20 trading days in any
30-consecutive-trading-day period.

At the second closing of the private placement on June 11, 1996, the 1,287,500
shares of Series A preferred stock were automatically converted to 321,875
shares of common stock. Notwithstanding such conversion, holders of the Series A
preferred stock have received pro rata 95.85% of shares of common stock of IPI
associated with the sale of the Product, as discussed in NOTE 2.

During 1997, Series B preferred stockholders converted 55,039 shares of
preferred stock into 1,421,392 shares common stock at the conversion price in
effect at the time. At December 31, 1997, the remaining 204,159 shares of Series
B preferred stock are convertible into 5,325,866 shares of common stock,
excluding the effect of any fractional shares.

CONVERSION RESET

In accordance with the terms of the placement, the Initial Conversion Price was
to be adjusted and reset effective as of the Reset Date if the average closing
bid price for the 30 consecutive trading days immediately preceding the Reset
Date (the 12-Month Trading Price) was less than 135% of the Initial Conversion
Price or $5.40. If such was the case, the Initial Conversion Price would be
reduced to be equal to the greater of the 12-Month Trading Price divided by 1.35
or 50% of the Initial Conversion Price.

                    Notes to Financial Statements (continued)

4. EQUITY TRANSACTIONS (CONTINUED)

The Initial Conversion Price was adjusted effective June 11, 1997, because the
average closing bid price of the common stock for the 30 consecutive trading
days immediately preceding such date was less than $5.40. The average was, in
fact, $5.175 per share. Accordingly, the conversion price was adjusted to $3.83
per share, which corresponds to a new conversion rate of 26.0875 shares of
common stock per share of Series B preferred stock.

STAGGERED LOCK-UP

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

In March 1997, the Company completed a revision to the staggered Lock-up and
Conversion Reset provision of the private placement. Shareholders owning
approximately 94% of the Series B preferred shares agreed to a modification of
the original subscription agreement, such that the staggered Lock-up would
expire beginning three months after both listing and effectiveness under the
Securities Act of 1933 of the Company's Registration Statement for its common
stock (Effectiveness). As so modified, upon listing and Effectiveness, which
occurred on July 10, 1997, 25% of the Conversion Shares were not subject to any
Lock-up provisions. The remaining 75% of the Conversion Shares were subject to a
staggered Lock-up, such that every three months after July 10, 1997, 25% of the
Conversion Shares are released from Lock-up until the ninth month, at which
point, all Conversion Shares will no longer be subject to any Lock-up.

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

STOCK OPTIONS

In April 1992, the Board of Directors approved the 1992 Stock Option Plan (the
Plan), which, as amended, authorizes up to 437,500 shares of common stock for
granting both incentive and nonqualified stock options to employees, directors,
consultants and members of the scientific advisory board of the Company. The
exercise price and vesting period of the options are determined by the Board of
Directors at the date of grant. Options may be granted up to 10 years after the
Plan's adoption date and generally expire 10 years from the date of grant.

The following summarizes activity in the Plan:

                                                           OPTIONS

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

All outstanding options were issued at an exercise price of $1.20 per share. At
December 31, 1997, options to purchase 30,000 shares of common stock were
exercisable, and options to purchase 407,500 shares of common stock were
available for grant under the Plan.

Certain officers and employees were also granted stock options in 1996, as
authorized by the Board of Directors, apart from the Plan. In May 1996, the
Company's President and Chief Executive Officer (the President) received options
to purchase 318,873 shares of common stock at $1.00 per share. Such options vest
at a rate of 1/16 per quarter over four years and are exercisable for a period
of seven years. Because the fair value of the Company's common stock at the date
of grant was determined to be $2 per share, the Company recorded $318,873 as
deferred compensation. Such deferred compensation is being amortized over four
years.

In September 1996, certain officers and an employee also received options to
purchase 252,500 shares of common stock at $1.00 per share. Such options vest at
a rate of 1/16 per quarter over four years and are exercisable for a period of
seven years. Because the

fair value of the Company's common stock at the date of grant was determined to
be $4 per share, the Company recorded $757,500 as deferred compensation. Such
deferred compensation is being amortized over four years.

In March 1997, one other employee of the Company received options to purchase
52,500 shares of common stock at $6.00 per share, the closing market price on
the date of grant. In July 1997, the Company withdrew such options and replaced
them with options to purchase 90,000 shares of common stock at an exercise price
of $4.50, the closing market price on the date of grant. The options vest as
follows: 5,000 shares vest on September 1, 1997, 30,000 shares vest at a rate of
1/6 every six months over a three-year period, thereafter, and the remaining
55,000 shares will vest upon the occurrence of certain milestone events relating
to the Company's manufacturing program. Such options are exercisable for a
period of seven years.

In July 1997, the President, certain officers and an employee also received
options to purchase 280,000 shares of common stock at $4.50 per share. The
President's options, which represent 150,000 of these options, vest at a rate of
1/12 per quarter over a three-year period. The remaining options vest at a rate
of 1/16 per quarter over four years and all are exercisable for a period of
seven years.

In July 1997, options were issued to a scientific consultant to purchase 30,000
shares of common stock at $4.50 per share. Such options vest at a rate of 1/3
per year over three years and are exercisable for a period of seven years.

In September 1997, four directors of the Company each received a grant of
40,000 options to purchase common stock at $4.50 per share. Such options vest at
a rate of 1/16 per quarter over four years, commencing on December 1, 1997, and
are exercisable for a period of seven years.

In December 1997, four directors of the Company each received a grant of 5,161
options to purchase common stock at $3.88 per share. Such options vest at a rate
of 1/4 per quarter over one year, commencing on March 1, 1998, and are
exercisable for a period of seven years.

SFAS NO. 123 DISCLOSURES

Pro forma information regarding net loss and net loss per share is required by
SFAS No. 123 and has been determined as if the Company had accounted for its
applicable stock options and warrants under the fair value method of the
statement.

The fair value for these options and warrants was estimated at the date of grant
using a Black-Scholes option pricing model with the following weighted-average
assumptions for 1997 and 1996, including a risk free interest rate of 5.50%, a
volatility factor of the expected market price of the Company's common stock of
 .392 and a weighted-average expected life of the option or warrant of 44 months.

4. EQUITY TRANSACTIONS (CONTINUED)

This model was developed for use in estimating the fair value of traded options
which have no vesting restrictions and are fully transferable. In addition,
option valuation models require the input of highly subjective assumption,
including the expected stock price volatility. Because the Company's stock
options and warrants have characteristics significantly different from those of
traded options and because changes in the subjective input assumptions can
materially affect the fair value estimate, in management's opinion, the existing
models do not necessarily provide a reliable single measure of the fair value of
its employee stock options or warrants.

For purposes of pro forma disclosures, the estimated fair value of the options
is amortized to expense over the option or warrant vesting period. The effects
of applying SFAS No. 123 for pro forma disclosures are not likely to be
representative of the effects on reported net income or losses for future years.
The Company's pro forma information follows:

Company's stock occurred over a three-year period.

LEASES

In August 1996, the Company entered into a three-year lease for office
facilities. The lease commenced in October with a monthly rental of
approximately $5,400, beginning in the fourth month. This lease was amended in
December 1997 to add additional office space for the remainder of the original
lease term which increased the monthly rental by approximately $2,700. This
lease is secured by an irrevocable standby letter of credit of which the lessor
is the named beneficiary. This $107,000 letter of credit expires at the end of
the original lease term and is automatically reduced by an equal amount each
year.

In December 1997, the Company entered into a 10-year lease agreement for
manufacturing facility space which commences in February 1998 and contains an
option to terminate after five years. The monthly rental is approximately
$10,400. The first month's rent was payable upon signing of the lease along with
a security deposit equivalent to two months rental. The first five months rental
will be rebated at the end of the fifth month. This lease is secured by a
one-year irrevocable standby letter of credit of which the lessor is the named
beneficiary. This $379,530 letter of credit automatically renews each December
and will be reduced by the amortized reduction of the landlord investment each
year.

                     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 "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. In addition, there are certain contractual
indemnification provisions contained in the Subscription Agreements of the
Series B Offering (Exhibit 4.6), the Series B Placement Warrants (Exhibit 4.12),
the Bridge Placement Warrants (Exhibit 4.7), the HTM Warrants (Exhibit 4.5), the
Meyerson Warrants (Exhibit 4.13), the Shear/Kershman and Castelli Warrants
(Exhibit 4.16), the Rutgers Warrants (Exhibit 4.17) and the warrants to be
issued to Drs. Wertheimer, Spana and Mermelstein (Exhibit 4.15) indemnifying
against certain liabilities the Company, its officers, directors, affiliates
and/or controlling person, including, in certain cases, Paramount Capital, Inc.,
a company wholly owned by a substantial shareholder of the Company, Lindsay A.
Rosenwald, M.D. In addition, the Company has obtained certain liability
insurance coverage for its directors and officers.

         The offer and sale of Units were conducted through the Company's

         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 believed that such investors were accredited investors. The
         Closing Dates were the only dates that the Company sold Units, and the
         Company timely filed a Form D (or amended Form D, as the case may be)
         on each of the Closing Dates. Each of the purchasers of the Units
         represented their intentions to acquire the securities for investment
         only and not with a view to, or for sale in connection with, any
         distribution thereof and appropriate legends were affixed to the share
         certificates issued in such transactions. The purchasers in such
         offering of Units were all the Selling Securityholders listed as such
         in the Registration Statement except for James D. Wolfensohn, Seymour
         Buehler and William J. Vanden Heuvel who are included in the list of
         selling Shareholders because of their ownership of shares of Common
         Stock issued upon exercise of Bridge Placements Warrants being
         registered hereby, and, employees of Paramount that are not included in
         the Registration Statement notwithstanding their purchase of units in
         the Series B Offering.

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



                                      II-2

         business of the Company. In addition, the recipients of securities in
         each such transaction represented their intentions to acquire the
         securities for investment only and not with a view to or for sale in
         connection with any distribution thereof and appropriate legends were
         affixed to the certificates issued in such transactions.

3.       On November 20, 1995, the Company entered into a License Agreement (the
         "TJU License Agreement') with Thomas Jefferson University ("TJU")
         pursuant to which TJU licensed to the Company certain patent and patent
         applications relating to a process for the modification of a patient's
         own tumor cells into a cancer vaccine (the "TJU License"). Pursuant to
         the TJU License Agreement, the Company issued 229,121.5 shares of
         Common Stock to each of TJU and Dr. David Berd, TJU's chief oncologist
         and the inventor of its cancer vaccine. In the stock subscription
         agreements ("Subscription Agreements") entered into by the Company, TJU
         and Dr. Berd on November 20, 1995, relating to the issuance of Common
         Stock to each of TJU and Dr. Berd, each of TJU and Dr. Berd
         represented, among other things, to the Company, and the Company
         believed, the following: that (i) it acquired the Common Stock for
         investment purposes only and not for resale for an indefinite period of
         time for its own account; (ii) it had such sophistication, knowledge
         and experience in financial and business matters as to be capable of
         evaluating the merits and risks of its investment in the Company; (iii)
         it had the ability to bear the economic risks of its investment for an
         indefinite period of time and could afford a complete loss of its
         investment; and (iv) it had access to information, and the opportunity
         prior to its purchase of the Common Stock to ask questions of and
         receive answers from representatives of the Company, in each case
         concerning the finances, operations and business of the Company. Also,
         as stated in the Subscription Agreements, the share certificates issued
         in connection with the above issuance of Common Stock had endorsed
         thereon legends regarding restrictions on the transfer of the Common
         Stock. Because of, among other things, the foregoing, the issuances of
         the above referenced securities was deemed to be exempt from
         registration under the Act in reliance on Section 4(2) thereof.

4.       The Castle Group, LLC ("The Castle Group") which may be deemed an
         affiliate of both the Company and the Placement Agent, identified,
         negotiated and acquired for the Company the TJU License. In connection
         therewith, The Castle Group and/or its designees were granted 916,485.5
         of Common Stock of the Company at a price of $.004 per share pursuant
         to an Engagement & Technology Acquisition Agreement dated October 20,
         1995 between The Castle Group and the Company. In the stock

         experience in financial and business matters as to be capable of
         evaluating the merits and risks of its investment in the Company; (iii)
         it had the ability to bear the economic risks of its investment for an
         indefinite period of time and could afford a complete loss of its
         investment; and (iv) it had access to information, and the opportunity
         prior to its purchase of the Common Stock to ask questions of and
         receive answers from representatives of the Company, in each case
         concerning the finances, operations and business of the Company. Also,
         as stated in the Subscription Agreements, the share certificates issued
         in connection with the above issuance of Common Stock had endorsed
         thereon legends regarding restrictions on the transfer of the Common
         Stock. Because of the foregoing, the issuances of the above referenced
         securities were deemed to be exempt from registration under the Act in
         reliance on Section 4(2) thereof because such issuances did not involve
         a public offering. In addition, each of the recipients of securities in
         such transaction represented their intention to acquire the securities
         for investment only and not with a view to or for sale in connection
         with any distribution thereof and conform to appropriate legends were

         recipients had adequate access, through their relationships with the
         Company, to information about the Company.

         Stock at an exercise price of $.004 per share. In June 1996, such
         bridge notes were paid by the Company and all the warrants were
         exercised by the holders thereof. In connection with services rendered
         as the placement agent of the bridge financing, Paramount Capital, Inc.
         ("Paramount") was issued warrants to purchase 31,250 shares of Common
         Stock at an exercise price of $.004 per share. In connection with the
         issuances of the Warrants and the Placement Warrants, each of the
         Warrant Holders and Paramount represented, and the Company believed,
         among other things, the following: that (i) it acquired the Common
         Stock for investment only and not for resale for an indefinite period
         for its own account; (ii) it had such sophistication, knowledge and
         experience in financial and business matters as to be capable of
         evaluating the merits and risks of its investment in the Company; (iii)
         it had the ability to bear the economic risks of its investment for an
         indefinite period of time and could afford a complete loss of its
         investment; and (iv) it had access to information, and the opportunity
         prior to its purchase of the Common Stock to ask questions of and
         receive answers from representatives of the Company, in each case
         concerning the finances, operations and business of the Company. Also,
         as stated in the Subscription Agreements, the share certificates issued
         in connection with the above issuances of Common Stock had endorsed
         thereon legends regarding restrictions on the transfer of the Common
         Stock. The issuances of the above referenced securities were deemed to
         be exempt from registration under the Act in reliance on Section 4(2)
         thereof because such issuances did not involve a public offering.

6.       On October 24, 1996, the Company entered into an agreement with M. H.
         Meyerson & Co., Inc. ("Meyerson"), pursuant to which Meyerson performed
         certain investment banking and financial advisory services on a
         non-exclusive basis for the Company (the "Meyerson Investment Banking
         Agreement"). Pursuant to the Meyerson Investment Banking Agreement,
         which was terminated by the Company on April 17, 1997, Meyerson
         acquired warrants to purchase an aggregate of 50,000 shares of Common
         Stock of the Company at an exercise price of $6.00 per share. At the
         time of the Company's termination, 25,000 of the Meyerson Warrants had
         vested. The issuance of the Meyerson Warrants was deemed to be exempt
         from registration under the Act in reliance on Section 4(2) thereof
         because such issuance did not involve a public offering. In addition,
         Meyerson represented its intention to acquire the securities for
         investment only and not with a view to or for sale in connection with
         any distribution thereof and appropriate legends are required to be
         affixed to the warrant certificates issuable in such transactions.
         Meyerson had adequate access, through its negotiations with the Company
         of the terms of the Investment Banking Agreement, to information about
         the Company.

7.       On December 10, 1996, the Company entered into a license agreement with
         Rutgers, the State University of New Jersey and the University of
         Medicine and Dentistry of New Jersey (collectively, "Rutgers") pursuant

         of Common Stock at a price of $8.24 per share to Rutgers (the "Rutgers
         Warrants"). The issuance of the Rutgers Warrants was deemed to be
         exempt from registration under the Act in reliance on Section 4(2)
         thereof because such issuance did not involve a public offering. In
         addition, Rutgers represented its intention to acquire the securities

         with any distribution thereof and appropriate legends are required to

         of the terms of the Rutgers License, 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 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 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 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 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 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 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 Act as part of
this registration statement as of the time it was declared effective.

         (2) For determining any liability under the 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.

                            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
Post-Effective Amendment No. 3 to the Registration Statement on Form SB-2 (the
"Registration Statement") filed with the Securities and Exchange Commission (the
"Commission") on March 16, 1998, Registration Number 333-09349, under the
Securities Act of 1933 (the "Act") for the registration under the Act of the
following securities of the Issuer:

                  (i) 1,209,234 shares of common stock, par value $.004 per
                  share ("Common Stock");

                  (ii) 5,096,785 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 49,229 shares of Common Stock issuable upon (a)
                  the conversion of shares of Series B Preferred Stock issuable
                  upon exercise of the warrants issued to the placement agent
                  and/or its designees relating to the offering of the Series B
                  Preferred Stock (the "Series B Placement Warrants") and (b)
                  exercise of warrants issued to the placement agent and/or its
                  designees for certain bridge financing transactions of the
                  Company (the "Bridge Placement Warrants," and together with
                  the Series B Placement Warrants, the "Placement Warrants").

                  In that connection, we have examined originals or copies,
certified or otherwise identified to our satisfaction, of certificates of public
officials and corporate records, instruments and documents of or affecting the
Issuer, including, without limitation, (i) the Certificate of

                                                                               2

Incorporation of the Issuer, as amended to date; (ii) the Bylaws of the Issuer,
as amended to date; (iii) resolutions adopted by the Board of Directors and
Stockholders of the Issuer; (iv) the Certificate of Designations for the Series
B Preferred Stock; (v) a form of specimen stock certificate for the Common
Stock; (vi) a form of specimen stock certificate for the Series B Preferred
Stock; (vii) a form of the Series B Placement Warrant; and (viii) a form of the
Bridge Placement Warrant. We have also examined originals or copies, certified
or otherwise identified to our satisfaction, of certificates of officers of the
Issuer, and have reviewed such questions of law and made such other inquiries,
as we have deemed necessary or appropriate for the purpose of rendering this
opinion.

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

emergencies at all times) to inspect, repair and/or clean the same, to show the
Premises to prospective purchasers, mortgagees, tenants, or insurers, or make
alterations or additions thereto, and Tenant shall not be entitled to any
abatement or reduction of rent by reason thereof.

of the date hereof, it is the owner in fee simple of the Premises and that it
has the right to enter into this Lease and to perform the obligations of
Landlord set forth herein. Nothing herein shall be construed as prohibiting
Landlord from further encumbering Landlord's reversionary interest by a deed of
trust and or mortgage, or from assigning the rents and profits hereunder.

          3.6 Miscellaneous Restrictions. Tenant agrees in using the Premises
not to commit any waste or suffer any waste to be committed upon the Premises,
nor to do or permit anything to be done on or about the Premises which will in
any way allow the Premises to be used for any unlawful purpose, nor to use or
permit to be used the Premises in any manner so as to create a hazard of fire or
other casualty, nor to cause, maintain or permit any nuisance in, on or about

          4.1 Improvements. Landlord agrees to provide the improvements pursuant
to the plans and specifications attached (or to be attached) hereto as Exhibits
"C" and "C-l" and incorporated herein by reference ("Improvements") at Tenant's
expense. In the event the plans and specifications are not attached to this
Lease as of the date of execution hereof, this Lease shall terminate at
Landlord's option, on the day next following the 14th day Tom the date hereof
unless Landlord and Tenant initial and attach the plans and specifications to

the Improvements have not been substantially completed pursuant to the plans
described on Exhibits "C" and "C-l", and a certificate of occupancy issued by

or anyone acting under or for Tenant, Landlord shall have no liability, and the
obligations of this Lease (including without limitation, the obligation to pay
rent) shall nonetheless commence as of the date specified in Section 21(i).

          (b) If the Improvements are not substantially completed pursuant to
the specifications contained in Exhibits "C" and "C-l", and a certificate of
occupancy issued by the City of Kansas City, Missouri, due to any reason other
than an omission, delay or default by Tenant or someone acting under or for
Tenant, then, as Tenant's sole remedy for the delay in Tenant's occupancy of the
Premises, Commencement Date shall be delayed as set forth in Section 2.1 and the
rent herein provided shall not commence until the earlier to occur of actual
occupancy by Tenant or substantial completion of the Improvements.

          4.4 Ownership of Improvements. Unless Landlord requires their removal
pursuant hereto or unless Tenant notifies Landlord in writing and obtains
Landlord's consent prior to making any such alterations of its intent to remove
same upon termination of this Lease, all alterations, repairs, additions,
utility installations, fixtures (except for movable equipment or furniture owned
by Tenant) and improvements of any nature to the Premises shall, at the
expiration or earlier termination of this Lease, become the sole property of
Landlord and remain upon and be surrendered with the Premises. Landlord shall

         5.1 Base Rental. Subject to the adjustments to Net Rentable Area set
forth in Section l.l (b) and Section l. l (d) and the limitations to such
adjustments set forth therein, Tenant agrees to pay to Landlord during the
Initial Lease Term, without prior demand therefore and without any offset or
deduction whatsoever, the monthly rent set forth below, as adjusted under
Section 5.2 hereof ("Base Rental"):

                Rent per
Monthly Rent    Square Foot    Time Period
- ------------    -----------    -----------

   0            0              Commencement Date through Month 3
$5,383.91       $23            Month 4 through Month 36

          The monthly Base Rental for each month, or portion thereof during the
Initial Lease Term, together with any estimated adjustments pursuant to Section
5.2 hereof, shall be due and payable in advance on the first day of each
calendar month during the Initial Lease Term and any extensions or renewals
thereof, and Tenant hereby agrees to pay such Base Rental and any adjustments
thereto to Landlord at Landlord's address provided herein (or such other address
as may be designated by Landlord in writing from time to time). The Base Rental
for the first month of the Lease Term for which Base Rental is due has been
deposited with Landlord by Tenant contemporaneously with the execution hereof If
the term of this Lease commences on a day other than the first day of the month
or terminates on a day other than the last day of the month, then the
installments of Base Rental and any adjustments thereto for such month or months
shall be prorated, based on the number of days in such month, and Landlord shall
return any overpayment made by Tenant.

          5.2 Additional Rent Adjustments. The Base Rental payable hereunder
shall be adjusted upward from time to time in accordance with the following
provisions:

          (a) Tower II contains 240,914 square feet of Net Rentable Area in
aggregate. Tenant's Base Rental is based, in part, upon the estimate that annual
Operating Costs (hereinafter defined) will be equal to $5.00/square foot of Net
Rentable Area in Tower II. Tenant shall, during the term of this Lease, pay as
an adjustment to Base Rental hereunder an amount (per each square foot of Net
Rentable Area within the Premises, including those portions of Common Areas
allocated to the Premises from time to time) equal to the excess of actual
Operating Costs per square foot in Tower II over the amount of $5.00/square foot
("Additional Rent"). Landlord may collect any Additional Rent in arrears on a
yearly basis. Landlord shall also have the option to make a good faith estimate
of the Additional Rent for each upcoming calendar year based on the actual
Operating Costs for the preceding calendar year, and may require the monthly
payment of Base Rental adjusted in accordance with such estimate of Additional
Rent. Any amounts paid based on such an estimate shall be subject to adjustment
pursuant to Subsection 5.2(b) when actual Operating Costs are available for each
calendar year.

          (b) If the actual Operating Costs in the previous calendar year are
more than the amount paid by Tenant through the course of the year, Tenant
agrees to pay the difference within ten (10) days of such determination. If the
actual Operating Costs in the previous calendar year are less than the amount
paid by Tenant and Tenant has overpaid Landlord, the amount of such overpayment
shall be credited to Tenant's continuing payments of Additional Rent until
exhausted, except that for the final year of the


                                       5
<PAGE>


Initial Lease Term, or any extension thereof, any overpayment will be rebated to
Tenant, provided Tenant shall not be in default under the Lease.

          For the purpose of determining the Additional Rent under this Lease,
the term "Operating Costs" shall mean all direct and indirect costs and expenses
in each calendar year of operating, maintaining, repairing, managing and owning
Tower II, the first floor of the link building between Twentieth Century Tower I
and Tower II and the Exterior Common Areas. "Exterior Common Areas" shall mean
those areas of the Real Proper SEW are not located within Tower II and which are
provided and maintained for the common use and benefit of Landlord and tenants
of Tower II generally and the employees, invitees and licensees of Landlord and
such tenants including, without limitation, all parking areas, enclosed or
otherwise and all streets, sidewalks and landscaped areas located within the
Real Property. Operating Costs shall not include the cost of any capital
improvements, depreciation, interest, and principal payments on mortgage and
other non-operating debts of Landlord. Operating Costs shall, however, include
the amortization of capital improvements which are primarily for the purpose of
reducing Operating Costs, or which are required by governmental authorities. The
Operating Costs shall include, but are not limited to, the following:

         1. The wages and salaries (including insurance benefits, vacation and
         sick leave) of all employees directly engaged in the operation and
         maintenance of the Premises, including employers' social security taxes
         and any other taxes which may be levied on such wages and salaries.

         2. The cost of all property management fees and maintenance and service
         agreements covering the Premises, including, but not limited to,
         equipment maintenance.

         3. Insurance premiums for fire, extended coverage and general liability
         coverage and for such other coverage with respect to the Premises that
         Landlord reasonably deems desirable, and legal and accounting expenses
         directly related to the Premises.

         4. The cost of repairs and general maintenance of the Premises
         including, but not limited to, those services enumerated in Sections
         6.1 and 6.2 (exclusive of expenses to accommodate other tenant(s)), and
         all other reasonable costs and expenses incurred by Landlord in
         performing its obligations hereunder. 5. All taxes and assessments
         (excluding penalties not due to the fault of Tenant), and governmental
         charges whether federal, state, county or municipal, which are levied
         on or charged against the Real Property, personal property, or rents,
         or on the right or privilege of leasing real estate or collecting rents
         thereon, and any other taxes and assessments attributable to the
         Premises, excluding, however, federal and state income taxes.

          The taxes and assessments allocable to the Operating Costs which are
to be paid by Tenant shall be the sum of the following:

          (i) the product obtained by multiplying the taxes assessed against the
Real Property by a fraction, the numerator of which is the total number of
square feet of floor area within the Premises, and the



                                       6
<PAGE>

denominator of which is the total number of square feet of floor area contained
within all of the improvements on the Real Property; plus

          (ii) the product obtained by multiplying the taxes and assessments
assessed against the improvements on the Real Property by a fraction, the
numerator of which is the total number of square feet of floor area contained
within the Premises, and the denominator of which is the total number of square
feet of floor area contained within all of the improvements on the Real
Property.

          (c) Tenant shall have the right, upon ten (10) days' written notice to
Landlord, to audit the books and records of Landlord relating to Operating Costs
during the year preceding the audit. Such audit shall be performed at the sole
expense of Tenant, within twenty-four (24) months after the end of the calendar
year for which such records are being questioned, no more than one time per year
and at the location where such books and records are normally kept by Landlord.
In the event such an audit demonstrates Additional Rent collected for such
preceding year to be higher or lower than the amount of Additional Rent actually
due pursuant to Subsection 5.2(a) above, then Landlord shall refund any
overpayment or Tenant shall remit any underpayment within ten (10) days of such
determination.

          5.3 Interest on Past Due Rent. If Tenant shall fail to pay within ten
(10) days after the same is due and payable any Base Rental or any Additional
Rent, Tenant shall, upon demand, pay Landlord interest on the past due amount
from the due date thereof to the date of payment at a rate equal to the lesser
of (i) two percent (2%) in excess of the prime rate Tom to time announced by
Boatmen's First National Bank of Kansas City, or (ii) the highest lawful rate
that may be charged to Tenant under the laws of the State of Missouri.

          (b) Routine maintenance and electric lighting service for all Exterior
Common Areas, Common Areas and Service Areas in the manner and to the extent

pay Landlord the sum of Fifteen and no/100 Dollars ($15.00) for each additional
replacement card(s). Landlord shall have no liability to Tenant, its employees,

regulations promulgated by Landlord with respect thereto; and

          (g) Maintenance services including, but not limited to, lawn care,

causes beyond the reasonable control of Landlord, shall not render Landlord
liable in any respect nor be construed as an eviction of Tenant, nor work an
abatement of rent, nor relieve Tenant from the obligation to fulfill any
covenant or agreement hereof Should any of the equipment or machinery used in
the provision of such services for any cause cease to function properly, Tenant
shall have no claim for offset or abatement of rent or damages on account of an
interruption in service occasioned thereby or resulting therefrom.

shall be effected in compliance with all applicable laws; provided, however, if
Tenant fails to make such repairs or replacements promptly, Landlord may, at its
option, make repairs or replacements, and Tenant shall pay the cost thereof to
the Landlord on demand. Tenant agrees with Landlord not to make or allow to be
made any alterations or additions to the Premises, other than the Improvements,
without first obtaining the written consent of Landlord in each such instance,
which consent may be given on such conditions as Landlord may elect but which
consent shall not be unreasonably withheld. Landlord's approval of any plans,
specifications or working drawings for Tenant's alterations shall create no
responsibility or liability on the part of Landlord for their completeness,
design sufficiency or compliance with all laws, rules and regulations of
governmental agencies or authorities. Landlord may require Tenant to remove any
and all fixtures, equipment and other improvements installed on the Premises. In
the event that Landlord so elects, and Tenant fails to remove such improvements,

<PAGE>

          (c) If Tenant's consumption of electrical services exceeds either the
rated capacities and/or design loads as per Subsections 7.3(a) and 7.3(b), or
generates heat in excess of that Landlord's air conditioning system is designed
to handle, then Tenant shall remove such equipment and or lighting to achieve
compliance within ten (10) days after receiving notice from Landlord, or upon
receiving Landlord's prior written approval, such equipment and/or lighting may
remain in the Premises, subject to the following:

          (i) Tenant shall pay for all costs of installation and maintenance of
submeters, wiring, additional air conditioning systems and other items required
by Landlord, in Landlord's discretion, to accommodate Tenant's excess design
loads and capacities or heat production.

          (ii) Tenant shall pay to Landlord, upon demand, the cost of the excess
demand and consumption to electrical service at rates determined by Landlord
(which rates shall be in accordance with any applicable laws) as well as all
costs of operating additional air conditioning systems deemed necessary by
Landlord on account of Tenant's excess consumption.

          (iii) Landlord may, at its option, upon not less than thirty (30)
days' prior written notice to Tenant, discontinue the availability of such
extraordinary utility service. If Landlord gives any such notice, Tenant will
contract directly with such public utility for the supplying of such utility
service to the Premises.

          7.4 Building Rules. Tenant will comply with the rules of Tower II and
the Real Property adopted and altered by Landlord from time to time and will
cause all of its agents, employees, invitees and visitors to do so. All changes
to such rules will be sent by Landlord to Tenant in writing with the initial
rules being attached hereto as Exhibit "D" and incorporated herein by reference.

                                  ARTICLE VIII

                              DAMAGE OR DESTRUCTION

          8.1 Damages Covered by Insurance. (a) If the Premises or any part
thereof shall be damaged by fire or other casualty, Tenant shall give prompt
written notice thereof to Landlord. In case Tower II shall be so damaged that
substantial alteration or reconstruction of Tower II shall, in Landlord's sole
opinion, be required (whether or not the Premises shall have been damaged by
such casualty) or in the event any mortgagee of Landlord's should require that
the insurance proceeds payable as a result of a casualty be applied to the
payment of the mortgage debt then, Landlord may repair and restore the Premises,
with rent and other charges payable by Tenant during this period abated or
equitably reduced as set forth in Section 8.3, or terminate this Lease as
provided in Subsection 8.1(b). If Landlord does not elect to terminate this
Lease, then Landlord shall within thirty (30) days after the occurrence of such
damage or destruction give notice to Tenant of the date by which Landlord
reasonably believes that restoration of the Premises and/or Tower II shall be
substantially completed (such date being herein referred to as the "Restoration
Date"). If such notice indicates that the Restoration Date shall not be on or
before a date which shall be ninety (90) days following the date of such damage
or destruction, then, Tenant shall have the right to terminate this Lease by
giving notice to Landlord not later than twenty (20) days after


                                       10
<PAGE>


receiving such notice, and in the event Tenant gives such notice, this Lease
shall be deemed terminated as of the date ten (10) days after Landlord's receipt
of Tenant's termination notice as if such date were the expiration date of the
Lease; provided, however, that Tenant shall have no right of termination in the
event the damage or destruction affects a part of Tower II that does not include
the Premises and does not impact Tenant's use of or access to the Premises. If
the foregoing proviso does not apply and Tenant has the right to termination but
does not elect to terminate this Lease, but Landlord shall thereafter fail to
substantially complete the restoration of the Premises and/or Tower II within
ninety (90) days following the date of such damage or destruction, then Tenant
shall have the right to terminate this Lease by giving written notice to
Landlord not later than one hundred (100) days following the date of the damage
or destruction and if Landlord shall fail to so complete such restoration within
fifteen (15) days following Landlord's receipt of Tenant's termination notice,
this Lease shall be deemed terminated as of the date of the casualty as if such
date were the expiration date of the Lease. The Premises shall be repaired and
restored by Landlord to substantially the same condition in which it was
immediately prior to the happening of the casualty, except that Landlord's
obligation to pay for such restoration shall not exceed the scope of the work
required to be done by Landlord at Landlord's expense in originally constructing
Tower II and installing the Improvements. Tenant shall pay to Landlord, on
demand, the cost of the reconstruction of all improvements in excess of those
Improvements originally installed at Landlord's expense, and Tenant shall be
responsible for the restoration of Tenant's furniture, equipment and other
personal property.

          (b) Landlord may elect to terminate this Lease pursuant to Subsection
8.1 (a) by giving notice to Tenant of its election to do so within thirty (30)
days after such occurrence. If Landlord exercises its right to terminate this
Lease, then this Lease shall cease, effective as of the date of such damage or
destruction, and all rent and other charges payable by Tenant shall be adjusted
as of that date.

          8.2 Damages Not Covered by Insurance. (a) If the Premises shall be at
any time damaged or destroyed by a casualty uninsured under the insurance
provisions of Article XI, so as to become partially or totally untenantable,
then Landlord shall have the right of either (i) repairing and restoring the
Premises, with rent and other charges payable by Tenant during this period
abated or equitably reduced as set forth in Section 8.3, or (ii) terminating
this Lease. Said election shall be made by Landlord within thirty (30) days of
Tenant's notice to Landlord of the occurrence of such casualty by giving notice
thereof to Tenant within such period.

          (b) If Landlord elects to rebuild and repair the Premises as set forth
in Subsection 8.2(a), then Landlord shall within thirty (30) days after the
occurrence of such damage or destruction give notice to Tenant of the date by
which Landlord reasonably believes that restoration of the Premises and/or Tower
II shall be substantially completed (such date being herein referred to as the
"Restoration Date"). If such notice indicates that the Restoration Date shall
not be on or before a date which shall be ninety (90) days following the date of
such damage or destruction, then, Tenant shall have the right to terminate this
Lease by giving notice to Landlord not later than twenty (20) days after
receiving such notice, and in the event Tenant gives such notice, this Lease
shall be deemed terminated as of the date ten (10) days after Landlord's receipt
of Tenant's termination notice as if such date were the expiration date of the
Lease; provided, however, that Tenant shall have no right of termination in the
event the damage or destruction affects a part of Tower II that does not include
the Premises and does not impact Tenant's use of or access to the Premises. If
the foregoing proviso does not apply and Tenant has the right to termination



                                       11
<PAGE>

but does not elect to terminate this Lease, but Landlord shall thereafter fail
to substantially complete the restoration of the Premises and/or Tower II within
ninety (90) days following the date of such damage or destruction, then Tenant
shall have the right to terminate this Lease by giving written notice to
Landlord not later than one hundred (100) days following the date of the damage
or destruction and if Landlord shall fail to so complete such restoration within
fifteen (15) days following Landlord's receipt of Tenant's termination notice,
this Lease shall be deemed terminated as of the date of the casualty as if such
date were the expiration date of the Lease Landlord shall be required to
complete the repair and restoration of Tenant's property to substantially the
same condition in which it was immediately prior to the happening of the
casualty, except that Landlord's obligation to pay for such restoration shall
not exceed the scope of the work required to be done by Landlord at Landlord's
expense in originally constructing Tower II and installing the Improvements.
Tenant shall pay to Landlord, on demand, the cost of the reconstruction of all
improvements in excess of those Improvements originally installed at Landlord's
expense, and Tenant shall be responsible for the restoration of Tenant's
furniture, equipment and other personal property.

          (c) If Landlord elects to terminate this Lease, then this Lease shall
terminate effective as of the date of the occurrence of the casualty and the
rent and other charges payable by Tenant shall be adjusted as of the date of
such casualty.

          8.3 Abatement or Reduction in Rent. If this Lease is not terminated as
set forth in Subsection 8.1(b) or Subsection 8.2(c), then (and as Tenant's sole
right against Landlord by reason of such damage or destruction), the annual rent
and other charges hereunder shall be abated or equitably reduced during any
period in which the Premises are rendered wholly or partially untenantable to
the extent such damage or destruction interferes with the operation of Tenant's
business in the Premises; provided, however, if the Premises or any other
portion of Tower II be damaged by fire or other casualty resulting from the
fault or negligence of Tenant or any of Tenant's agents, employees, or invitees,
the rent hereunder shall not be diminished during the repair of such damage and
Tenant shall be liable to Landlord for the cost of the repair and restoration of
Tower II caused thereby to the extent such cost and expense is not covered by
insurance proceeds. Such abatement or reduction shall continue for the period
commencing with such destruction or damage and ending fifteen (15) days after
Landlord completes its repair or restoration as set forth in Subsection 8.1(a)
or Subsection 8.2(b), or when Tenant reopens the Premises for business,
whichever is earlier. Landlord shall not be liable for any inconvenience or
annoyance to Tenant or injury to the business of Tenant resulting in any way

diminution of rent during the time and to the extent the Premises are wholly or
partially untenantable.

                                  CONDEMNATION

          9.1 Total Taking If the whole of Tower II or the Premises shall be
condemned by eminent domain for any public or quasi-public use or purpose or be
conveyed in lieu thereof, then the term of this Lease shall terminate as of the

other charges hereunder shall be adjusted as of that date.

<PAGE>

          9.2 Partial Taking If twenty percent (20%) or more of Tower II shall
be acquired or condemned as aforesaid, and if such partial taking or acquisition
renders the Premises unsuitable for the operation of Tenant's business therein,
then the term of this Lease shall terminate as of the date possession shall be
taken by the acquiring authority, and Base Rental and other charges shall be
adjusted as of the date of such termination. In the event of a partial taking or
acquisition which is not extensive enough to render Tower II or the Premises
unsuitable for such use then Landlord shall, to the extent only of the
condemnation proceeds received by Landlord, promptly restore Tower II and
Premises to a condition comparable to its condition at the time of such
condemnation, less the portion lost in the taking, and this Lease shall continue
in full force and effect and the rent shall be reduced in the same proportion
that the floor area remaining in the Premises after the taking bears to the
floor area in the Premises immediately prior to such taking.

          9.3 Condemnation Award. In the event of any condemnation or conveyance
in lieu thereof of the Premises, whether whole or partial, Tenant shall have no
claim against Landlord or the condemning authority for the value of the
unexpired Lease Term, and Tenant shall not be entitled to any part of the
compensation or award, whether paid as compensation for diminution in value to
the leasehold or to the fee of the Premises, and Landlord shall receive the full
amount thereof, Tenant hereby waiving any right to any part thereof and
assigning to Landlord its interest therein; provided, however, (i) Tenant shall
have the right to claim and recover from the condemning authority (but not from
Landlord) such compensation as may be separately awarded to Tenant in Tenant's
own name and right on account of all damage to Tenant's business by reason of
the condemnation and any cost which Tenant may incur in removing its personal
property from the Premises including the increase, if any, of the lease rate for
the new premises over the Base Rental described in Section 5.1, for the duration
of the Initial Lease Term or any extension thereof; and (ii) if this Lease is
terminated by reason of a condemnation of all or a part of the Premises,
Landlord shall pay to Tenant, to the extent of the condemnation award only,
Tenant's unamortized cost of installing permanent leasehold improvements (less
Landlord's contribution toward the Improvements) in the Premises as disclosed on
the books used by Tenant for federal income tax purposes; provided, however,
Tenant's rights to recover under this paragraph shall be subordinate to the
rights of the holder of the first mortgage on the Premises.

          9.4 Temporary Taking The taking of the Premises or any part of the
Premises by public authority shall constitute a taking of the Premises by
condemnation only when the use and occupancy by the taking authority is
continued for longer than one hundred eighty (180) consecutive days. During the
one hundred eighty (180) day period all provisions of this Lease shall remain in
full force and effect, except that rent shall be abated or reduced during such
period of taking based on the extent to which the taking interferes with
Tenant's use of the Premises.

         In the event any of the above provisions of this Subsection 10.1(d)

Premises, shall not become an asset in any of such proceedings and, in any such
events and in addition to any and all rights or remedies of the Landlord
hereunder or by law provided, it shall be lawful for the Landlord to declare the
term hereof ended and to reenter the Premises and take possession thereof and
remove all persons therefrom, and the Tenant shall have no further claim thereon

or after the expiration of the Lease Term, but the period of limitations shall

is entitled under the Lease. No reentry by Landlord shall constitute an election
to terminate this Lease unless Landlord gives Tenant written notice of

remedy which it may have for possession or arrearages in rent, expel or remove
Tenant and any other person who may be occupying said Premises or any part

shall have the right to secure the Premises by changing the locks or placing
additional locks thereon or by such other action as Landlord shall determine to
be reasonable to secure the Premises, and no such action taken to secure the
Premises shall be deemed an exclusion of Tenant Mom the Premises, nor shall any
such action be deemed to be an election by Landlord to take possession of the
Premises and to terminate this Lease; or

         (f) Exercise all other remedies available to Landlord at law or in
equity, including, without limitation, injunctive relief of all varieties. All
Landlord's remedies shall be cumulative and not exclusive. Forbearance by
Landlord to enforce one or more of the remedies herein provided upon an



                                       15

Event of Default shall not be deemed or construed to constitute a waiver of such
default. In addition, the provisions of Article XVIII hereof shall apply with
respect to the period from and after the giving of notice of such termination to
Tenant.

         10.3 Events of Default of Landlord. Landlord shall be in default
hereunder in the event Landlord has not begun and pursued with reasonable

Tenant's remedies for default hereunder and for breach of any promise of
inducement shall be limited to a suit for damages and/or injunction. In

Landlord and thereafter Landlord shall have no further liability for the return

Security Deposit in the form of an irrevocable letter of credit in a form
satisfactory to Landlord from a commercial bank with a B Rating or better
according to Scheshunoff Bank Quarterly or if no longer available, a similar
publication satisfactory to Landlord, which will be converted to cash to be

provided by Tenant each year during the Initial Lease Term.

assignment or subletting, specifying the name and address of the proposed
transferee and the terms of such proposed assignment or subletting.

          (c) Notwithstanding any assignment or sublease, Tenant shall remain
fully liable on this Lease and shall not be released from performing any of the
terms, covenants and conditions hereof If Tenant is a corporation, any sale,
transfer or other disposition of fifty-one percent (51%) or more of the
corporate stock shall be deemed to be an assignment. Notwithstanding the
foregoing, Tenant may, upon delivery of notice thereof to Landlord but without
Landlord's consent, assign this Lease or sublet all or any part of the Premises
to any entity in which Tenant owns a majority or controlling interest or to any
entity owned or controlled by the same entity as Tenant, or to any entity which
acquires (by purchase, merger or otherwise) all or a controlling interest in
Tenant; provided Tenant is not in default under the terms, covenants or
conditions of the Lease at the time of such assignment or subletting, and
provided that such assignee or sublessee does not intend to alter the use being
made of the Premises by Tenant and does not violate any exclusive use commitment
granted to any third party tenant. With respect to a corporation, "controlling
interest" shall mean the right to exercise fifty percent (50%) or more of the
voting rights attributable to the shares of such corporation. With respect to a
non-corporation, such control shall mean the possession of the power to direct
or cause the direction of the management or policies of such affiliate..
Tenant's assignee or sublessee shall be required to assume all of Tenant's
obligations under this Lease as to the space assigned or sublet.

          (d) If (i) the Premises are underlet or occupied by anybody other than
Tenant and Tenant is in default hereunder, or (ii) this Lease is assigned by
Tenant, then Landlord may collect rent Tom the assignee, undertenant or
occupant, and apply the net amount collected to the rent herein reserved; but no
such collection shall be deemed a waiver of the provision of this Article XVII,
or the acceptance of such assignee, subtenant or occupant as Tenant, or a
release of Tenant Tom further performance of the covenants herein contained.

in accordance with the following schedule:

          (1) SELECTION OF ARCHITECT AND ENGINEER. Tenant shall select an

shall continue to submit names to Landlord until the Architect and the Engineer
are finally approved by Landlord and written consent has been delivered to and
received by Tenant. Landlord hereby approves Rees Architecture as the Architect
and the parties agree that no Engineer will be utilized for the Improvements.

          (2) PREPARATION AND APPROVAL OF SPACE PLAN. Tenant shall submit to the
Architect all information including occupancy requirements for the Premises

Plan for Landlord's review and approval. Landlord shall either approve or
disapprove the Space Plan within ten (10) days of receipt, for reasonable and
material reasons (which shall be limited to the following: (i) adverse effect on
the structural integrity of Tower II (ii) possible damage to the Tower II
systems, (iii) non-compliance with applicable codes; (iv) adverse affect on the
appearance of Tower II [each a "Design Problem"]) and return the Space Plan to
Tenant. In the event of a disapproval of the Space Plan, Tenant shall make the
changes necessary in order to correct the Design Problem(s) and shall return the
Space Plan to Landlord, which Landlord shall approve or disapprove within three
(3) days of receipt. This procedure shall be repeated until the Space Plan is
finally approved by Landlord and written approval has been delivered to and
received by Tenant.

         NOW THEREFORE, for and in consideration of the sum of Ten and No/100
Dollars ($10.00) and other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties agree as follows:

         1. Section 1.1 is hereby modified by deleting the first sentence and
replacing it with the following sentence:

         "1.1 Lease Premises. Landlord hereby leases to Tenant, and Tenant
         hereby leases from Landlord, that portion of Tower II consisting of
         approximately 4,136 square feet of Net Rentable Area as delineated on
         the floor plan attached hereto as Exhibit "B-1" and incorporated herein
         by reference ("Premises")."

         2. Section 5.1 is hereby modified by deleting the first paragraph and
replacing it with the following paragraph:

         "5.1 Base Rental. Subject to the adjustments to Net Rentable Area set
         forth in Section 1.1(b) and the limitations to such adjustments set
         forth therein, Tenant agrees to pay to Landlord during the Initial
         Lease Term, without prior demand therefore and without any offset or
         deduction whatsoever, the monthly rent set forth below, as adjusted
         under Section 5.2 hereof ("Base Rental"):

                                                             Rent per
         Monthly Rent     Square Feet      Square Foot       Time Period
         ------------     -----------      -----------       -----------
               0             2809               0            9/23/96-12/22/96
           $5,383.91         2809             $23.00         12/23/96-9/22/99
           $2,709.29         1327             $24.50         12/1/97-9/22/99"

         The following new sentence is added to the end of the second paragraph
of Section 5.1:

         "Beginning December 1, 1997 through and including September 22, 1999,
         Base Rental for the 1,327 square feet of Net Rentable Area described in
         the dark gray cross-hatched area on Exhibit B-1 shall be $24.50 per
         square foot of Net Rentable Area."

         3. The following new Section 22 shall be added to the Lease:

         "22. Second Security Deposit. Contemporaneously with the execution of
         this First Amendment, Tenant shall deposit Sixty Six Thousand and
         No/100 Dollars ($66,000.00) into an American Century-Benham Cash
         Reserve account in the name of Avax Technologies, Inc. and Tenant shall
         authorize Landlord's Senior Vice President of Facilities and Real
         Estate as co-signer with individual authority on such Cash Reserve
         account ("Second Security Deposit"). Such Second Security Deposit shall
         be in addition to the Security Deposit described in Section 13.3 of the
         Lease


<PAGE>



         and shall be additional security for the performance by Tenant of
         Tenant's covenants and obligations under this Lease, as amended, it
         being expressly understood that such Second Security Deposit shall not
         be considered an advance payment of rental or a measure of Tenant's
         damages in case of default by Tenant. Landlord may, from time to time,
         without prejudice to any other remedy, withdraw the Second Security
         Deposit to the extent necessary to make good any arrearages of rent or
         to satisfy any other covenant or obligation of Tenant hereunder.
         Following any such application of the Second Security Deposit, Tenant
         shall invest in the Cash Reserve account on Landlord's demand the
         amount so applied in order to restore the Second Security Deposit to
         its original amount. All interest and earnings on the Cash Reserve
         account shall be payable to Tenant. At the end of each quarter of each
         calendar year during the Initial Lease Term, Tenant has the right to
         withdraw from the Second Security Deposit in the Cash Reserve account;
         provided, however, at all times, the amount invested in such Cash
         Reserve account shall be equal to the Base Rental remaining due under
         the Initial Lease Term on the 1,327 square feet added under this First
         Amendment. If Tenant is not in default at the termination of this
         Lease, the balance of the Second Security Deposit remaining after any
         such application may be withdrawn by Tenant and Landlord's Senior Vice
         President of Facilities and Real Estate shall no longer be authorized
         on the Cash Reserve account. If Landlord transfers its interest in the
         Premises during the term of this Lease, Landlord may assign the Second
         Security Deposit to the transferee, and an authorized signer of such
         transferee shall be authorized on the Cash Reserve account in lieu of a
         representative of Landlord and thereafter Landlord shall have no
         further liability for the return of such Second Security Deposit.
         Notwithstanding the foregoing, Tenant may, at Tenant's option, in lieu
         of providing the Second Security Deposit in the form of cash invested
         in an American Century-Benham Cash Reserve account as described above,
         provide such Second Security Deposit in the form of an irrevocable
         letter of credit in a form satisfactory to Landlord from a commercial
         bank with a B Rating or better according to Scheshunoff Bank Quarterly
         or if no longer available, a similar publication satisfactory to
         Landlord, which will be converted to cash to be retained by Landlord,
         in the event of a default under this Lease, as amended. Such letter of
         credit may provide for a reduction at the end of each quarter of each
         calendar year during the Initial Lease Term from the amount required to
         be provided by Tenant following the effective date of this First
         Amendment; provided, however, at all times, the amount provided under
         such letter of credit shall be equal to the Base Rental remaining due
         under the Initial Lease Term on the 1,327 square feet added under this
         First Amendment."

         4. Article XX is hereby amended by deleting the fourth sentence and
replacing it with the following sentence:

         "Tenant shall have the option to lease from Landlord throughout the
         Initial Lease Term up to thirteen (13) spaces in such covered parking
         area, such spaces to be on a first come-first serve basis."

         5. Except as expressly modified by this First Amendment, Landlord and
Tenant agree that the Lease shall remain in full force and effect in accordance
with its terms, and that all terms used herein shall have the same meaning
ascribed to them as in the Lease.

SPECIAL PROVISIONS

         1. Renewal Terms. Provided that no Event of Default has occurred
hereunder and is continuing, Tenant shall have the option to renew the term of
this Lease for up to two (2) additional terms of five (5) years each ("Renewal
Terms"), at a Fixed Minimum Rent per annum, to remain constant throughout the
five-year Renewal Term, equal to the lesser of (a) one hundred twenty percent
(120%) of the average Fixed Minimum Rent per annum in effect over the expiring
Term, or (b) ninety-five percent (95%) of the fair market value (including
applicable concessions, if any) for comparable leases in comparable buildings,
as determined by Landlord ("Fair Market Rent"). Tenant must notify Landlord of
Tenant's interest in renewing this Lease at least nine (9) months prior to the
expiration of the Initial Term, or the first Renewal Term, as the case may be (
failing which notice, Tenant's right to renew this Lease shall terminate and
expire), and Landlord shall, within thirty (30) days after receipt of such
notice, provide Tenant with the Fair Market Rent for the applicable Renewal
Term. Tenant must then notify Landlord of Tenant's renewal of this Lease at
least six (6) months prior to the expiration of the Initial Term, or the first
Renewal Term, as the case may be, failing which notice, Tenant's right to renew
this Lease shall terminate and expire. All terms and conditions of this Lease
other than the Fixed Minimum Rent shall apply to the Renewal Terms. The Initial
Term and Renewal Terms are hereafter collectively called the "Term".

         2. Parking. Landlord shall supply Tenant with three (3) free parking
spaces in the Building garage as part of the Fixed Minimum Rent, and all parking
in the garage shall be

                                                                             iii

<PAGE>

subject to the requirements of Exhibit E, which shall be strictly observed by
Tenant. In addition, if, as and when Landlord obtains control of additional
outdoor parking across 20th Street, Tenant shall have the right, at Tenant's
expense, to purchase monthly parking spaces from Landlord at the same price as
is offered to the public.

         3. Option to Terminate. Tenant shall have the one-time option to
terminate this Lease, effective as of the last day of the fifth (5th) Lease
Year, by giving Landlord written notice no later than nine (9) months before
such effective date, accompanied by a termination payment equal to the
unamortized portion, calculated as of the effective date of such termination, of
all expenses incurred by Landlord directly related to the transaction recorded
herein, based upon a ten (10) year amortization period of such expenses,
assuming that the amount of such expenses has accrued interest at ten percent
(10%) per annum, all as shown on Schedule 2. Landlord shall provide Tenant with
the amount of such termination payment within ten (10) business days after
request therefor,

         4. Expansion Option. Tenant shall have the right of first offer to
lease all space in the Building immediately adjacent to the Premises, if, as and
when such space becomes vacant during the Term hereof ("Option Space"). To
exercise such right, Tenant must give Landlord notice at least nine (9) months
before the expiration of each of the following leases for Option Space:

Landlord shall promptly give Tenant notice of any extensions or renewals of any
of the foregoing leases. All of the terms of this Lease (including, without
limitation, the then-effective Fixed Minimum Rent per square foot and any future
increases, and all parking ratios) shall apply to the Option Space, and Tenant's
lease of the Option Space shall be co-terminus with the expiration of the Term
hereof. Tenant shall not be entitled to exercise its option to add any Option
Space to the Premises if the remaining Term of this Lease on the effective date
of such option is less than three (3) years, unless Tenant exercises any
remaining Renewal Term at the same time as exercising its option to lease the
Option Space. Tenant shall be conclusively deemed to have waived its right to
lease any particular portion of the Option Space if Tenant fails to give timely
notice of the exercise of such option as set forth above.

         5. Storage Space. Landlord will make available to Tenant storage space
in the Building if, as and when such space is available from time to time, at
the rate of $4.00 per square foot. Any particular storage space must be vacated
by Tenant on 30 days' notice if such space is

                                                                              iv

business located in the Building will not be available for such storage use by
Tenant.

         6. Availability of Premises. Tenant shall have 24 hour, 7 day per week
access to the Premises. Building services will be provided from 6:00 a.m. to
7:00 p.m. weekdays and 7:00 a.m. to 2:00 p.m. on weekends and holidays, with
after-hours access requiring use of an access card.

         7. Cleaning. Landlord shall include basic office cleaning services for
the Premises each weekday, but shall not clean lab space or remove any hazardous
materials. Landlord shall only remove regular office trash, which Tenant shall
collect for Landlord separately from other refuse; all other refuse shall be
removed by tenant at Tenant's expense. Attached hereto as Exhibit F are
Landlord's cleaning specifications.

         8. Condition Precedent. As a condition precedent to Tenant's
obligations hereunder, Landlord has represented to Tenant that the use described
above is permitted under applicable provisions of the Zoning Code. If Tenant is
unable to obtain written confirmation of Tenant's right to occupy the Premises
for such use within fifteen (15) days after the date hereof, Tenant shall so
inform Landlord and Landlord shall make or complete the zoning use application
on behalf of Tenant. If Landlord does not deliver a zoning use permit within
forty-five (45) days thereafter, Tenant, as Tenant's sole remedy, may either
waive such condition or terminate this Lease and have the security deposit
refunded and the letter of credit returned (such right to terminate to expire if
Tenant does not terminate this Lease within sixty-five (65) days after the date
hereof).

         9. Subordination. Tenant may terminate this Lease without liability if
Tenant does not receive a nondisturbance agreement within thirty (30) days after
the date hereof.

         IN WITNESS WHEREOF, the parties hereto, intending to be legally bound
hereby, have hereunto set their hands and seals the day and year first above
written.

the Commencement Date, as defined in the Lease Summary, and shall terminate at
the end of the term without the necessity of any notice from either Landlord or
Tenant.

SECTION 1.02 Inability to Deliver Possession. If Landlord is unable to deliver

beyond the reasonable control of Landlord, including, without limitation, the
holding over of a prior tenant, Landlord shall have no liability to Tenant
therefor, and during the period that Landlord is unable to deliver possession,
all rights and remedies of both parties hereunder shall be suspended. However,
if Landlord can deliver possession of Suite 200, Tenant shall accept occupancy
of such portion and the Fixed Minimum Rent shall be pro rated accordingly, based
on the square footage of the portion being delivered, until the full Premises
becomes available. In the event that Landlord is unable to deliver to Tenant
possession of the Premises within 120 days after the date hereof (for reasons
not within Tenant's control), Tenant shall receive a credit against the Fixed
Minimum Rent in the amount of one-half day's rent for each day after 120 that
delivery of possession is so delayed.

SECTION 1.03 Failure of Tenant to Open and to Operate. Tenant agrees that upon
receiving possession of the Premises from Landlord, Tenant shall with due
diligence proceed to install such fixtures and equipment and to perform such
other work as shall be necessary or appropriate in order to prepare the Premises
for the opening of business. If Tenant fails to open the Premises for the
conduct of its business or vacates the Premises prior to the expiration of the
term hereof, Landlord, in addition to all other remedies hereunder, shall have
the option of terminating this Lease by giving Tenant written notice of such
termination, whereupon this Lease shall be terminated.

SECTION 1.04 Lease Year. The term "Lease Year" as used in this Lease shall mean
the twelve (12) month period beginning with the Commencement Date and ending on
the next anniversary of the Commencement Date and each successive twelve (12)
month period thereafter during the term of this Lease.

whether or not the same are designated "additional rent", shall for all purposes
hereunder be deemed and shall be paid by Tenant as rent. In the event that
Tenant shall fail to pay any installment of Fixed Minimum Rent or any other
money or charges required to be paid by Tenant within ten (10) days after the
date the same is due and payable, then Landlord shall have, in addition to all
other remedies to which Landlord may otherwise be entitled, the right to receive
from Tenant, in addition to such amount due and owing, (i) a late charge equal
to five percent (5%) of the overdue amount, and (ii) interest at the rate of 18%
per annum, beginning ten (10) days after the date any such payment is due, as
and for a late charge to defray Landlord's costs and expenses in collecting such
delinquent rental. Such late charge and interest shall be due and payable as set
forth above without regard to any notice requirements set forth in Section 20.01
hereof.

SECTION 3.03 Security Deposit. The security deposit shall be held as collateral
security for the payment by Tenant of all rents and other charges under this
Lease, and for the faithful performance of all other covenants and agreements of
Tenant hereunder; the cash portion of the security deposit, with interest at
five percent (5%) per annum, shall be repaid to Tenant, and the letter of credit
will be returned to Tenant, within thirty (30) days after the termination of
this Lease or any renewal or extension thereof, provided Tenant shall have made
all such payments and performed all such covenants and agreements. Upon any
Event of Default by Tenant hereunder, all or part of the deposit (including,
without limitation, the proceeds of the letter of credit) may, at Landlord's
option, be applied on account of such default, and thereafter Tenant shall
restore the resulting deficiency in the deposit upon Landlord's demand. Landlord
may deliver the deposit to any purchaser of Landlord's interest in the Premises
and, thereupon, Landlord shall be discharged from any further liability with
respect to the deposit, and Tenant shall look solely to such purchaser for the
return of the deposit. Landlord may also draw down the proceeds of the letter of
credit if Landlord fails to receive a substitute letter of credit at least
thirty (30) days before the expiration or termination of the letter of credit.

do or perform such other acts in and to Common Areas as Landlord shall determine
to be advisable; and to make all rules and regulations pertaining to and

for Tenant's use of the Premises.

SECTION 5.02 Operating Costs. Subject to reimbursement as herein set forth,
Landlord shall operate and maintain or cause to be operated and maintained the
Common Areas and the Building. For each Accounting Period (as defined in Section

fifteen percent (15%) of all of the foregoing costs to cover administrative and

specifically referred to above, replacements of capital items or capital
improvements or the items listed on Schedule 5.02. Tenant shall have the right
to have Landlord's Operating Costs audited at Tenant's expense as set forth
below, provided that an audit shall not delay or postpone payment of Tenant's
Pro Rata Share of Operating Costs or any deficiency as set fort in Section 5.05.
In the event of any dispute as to the floor area in the Building or any portion
thereof, the determination of Landlord shall be binding upon the parties absent
manifest error. Tenant will have the right to audit books and records detailing
Operating Costs and Taxes. If Tenant desires to audit Landlord's books and
records with respect to a calendar year, Tenant shall notify Landlord within
ninety (90) days after Tenant's receipt of a statement of Operating Costs with
respect to such calendar year. Tenant will then have sixty (60) days after the
giving of such notice within which to conduct such audit, and, if required, to
notify Landlord of Tenant's complaint. If any such audit should disclose that
Tenant's Pro Rata Share of Operating Costs or of Taxes have been overstated by
more than five percent (5%), then Landlord will immediately pay Tenant the full
amount of overpayment by Tenant together with interest on such overpayment the
rate of ten percent (10%) per year. In addition, if any such audit should
disclose that Tenant's Pro Rata Share of Operating Costs and Taxes have been
overstated by more than ten percent (10%), then Landlord will immediately pay
Tenant's reasonable out of pocket expenses, including, without limitation, all
accounting fees, incurred by Tenant in such audit.

SECTION 5.03 Payments on Account of Operating Costs. On the first day of each
calendar month after receipt of notice from Landlord that Taxes have increased
above the Base Tax Year or projected Operating Costs have increased above the
Operating Costs Base Year, Tenant shall pay to Landlord, in advance, without
demand and without any set off or deduction, as a payment on account of Tenant's
Pro Rata Share of Operating Costs, the amount equal to one twelfth (1/12) of the
annual amount estimated by Landlord from time to time to be Tenant's Pro Rata
Share of Operating Costs. If the Commencement Date shall not be the first day of
a calendar month, Tenant's payment of its share of Operating Costs for the
fractional month


                                      -7-
<PAGE>



between the Commencement Date and the first day of the first full calendar month
in the term shall be prorated on a per diem basis (calculated on a thirty (30)
day month) and shall be paid together with the first payment of fixed minimum
rent. Landlord may at any time and from time to time adjust the monthly payments
on account on the basis of Landlord's revised estimate of Operating Costs, and
Tenant shall pay such adjusted amount upon notice from Landlord.

SECTION 5.04 Landlord's Statement of Operating Costs. Following the end of each
Accounting Period, Landlord shall furnish to Tenant a written statement covering
the Accounting Period just expired showing the total Operating Costs for such
Accounting Period (with reasonable back-up), the amount of Tenant's Pro Rata
Share thereof and payments made by Tenant with respect thereto.

SECTION 5.05 Payment of Balance of Operating Costs. If Tenant's Pro Rata Share
of Operating Costs exceeds Tenant's payments with respect to any Accounting
Period, Tenant shall pay to Landlord the deficiency within thirty (30) days
after the date of the furnishing of the statement from Landlord; if Tenant's
payments exceed Tenant's Pro Rata Share of the Operating Costs, Landlord shall
apply such excess to future payments on account of Operating Costs; provided, if
such overpayment is for the last Accounting Period, Landlord shall not be
obligated to refund to Tenant the amount of such overpayment until Tenant has
fully performed all of its obligations under this Lease. In the event Tenant is
indebted to Landlord for any reason whatsoever, Landlord may deduct such amount
owed from such overpayment.

SECTION 5.06 Accounting Period; Prorations of Operating Expenses. The words
"Accounting Period" mean the period consisting of twelve (12) consecutive
calendar months, commencing on a date determined by Landlord from time to time
(the initial Accounting Period shall run from October 1 to September 30) and
each succeeding twelve (12) calendar month period thereafter commencing in the
term of this Lease. If the term of this Lease commences other than on the first
day of an Accounting Period or terminates (other than by reason of Tenant's
default) prior to the last day of any Accounting Period, Tenant's obligations
for Tenant's share of Operating Costs for such Accounting Period shall be
prorated on a per diem basis (calculated on a 360 day year).

or improvements now or hereafter made to the Building, all real estate taxes,
assessments, water and sewer fees, rents or charges not based on usage, and
other governmental impositions and charges of any kind whatsoever, nonrecurring
as well as recurring, special or extraordinary as well as ordinary, foreseen and

SECTION 6.02 Payments on Account of Tax Rent. For each Lease Year, Tenant shall
pay to Landlord the amount (hereinafter called "Tax Rent") obtained by
multiplying the total of all Taxes payable during such Lease Year, to the extent
such Taxes exceed the Taxes for the Base Tax Year, by Tenant's Pro Rata Share.
On account of Tax Rent, Tenant shall pay monthly, in advance, together with each
monthly installment of fixed minimum rent, without demand, set off or
counterclaim, an amount equal to one twelfth (1/12) of the annual amount
estimated by Landlord from time to time to be Tenant's Pro Rata Share of all
Taxes. Such amount may be adjusted by Landlord at any time and from time to time
during the term hereof on the basis of Landlord's revised estimate of Taxes, and
Tenant shall pay such adjusted amount upon notice from Landlord. If Tenant's
total payments on account of Tax Rent for any Lease Year exceed the actual
amount payable by Tenant as Tax Rent for such Lease Year, Landlord shall retain
such excess on account of future Tax Rent. In the event Tenant is indebted to
Landlord for any reason whatsoever, Landlord may deduct such amount owed from
such overpayment. At the termination of the Lease, Landlord may retain any
overpayment until Tenant has performed all of its obligations under the Lease.

SECTION 6.03 Payment of Balance of Tax Rent. Landlord shall have the right to
bill Tenant for Tax Rent at any time after each receipt by Landlord of a bill

taxes, and Tenant's payments theretofore made on account of such Tax Rent.

THE FOREGOING, TENANT SHALL PAY ITS USE AND OCCUPANCY TAX TO LANDLORD, AS
REQUIRED BY LAW, AND LANDLORD SHALL REMIT ANY AMOUNTS SO PAID TO THE APPROPRIATE
GOVERNMENTAL AUTHORITY.

all charges for electricity (including air conditioning), gas, heat, water,
sewer and all other utilities used or consumed in or upon the Premises and
separately metered to Tenant, as and when the charges therefor shall become due
and payable. Tenant acknowledges that Landlord intends to furnish electricity to
the Building and the Premises, and Tenant agrees to pay Landlord promptly upon
billing Tenant's electricity usage based on the local utility company's general
service rate and upon Tenant's usage as determined by a separate demand register
KW/KWH to be installed by Landlord at Landlord's expense. Landlord shall be
entitled to terminate electric service in the event that Tenant fails to pay any
electric bill for a period of forty-five (45) days. In the event any utility is
furnished by the local utility company, and the Building is billed as a single
entity therefor, Landlord shall have the right to determine Tenant's share of
such charges and bill Tenant therefor, which bill Tenant shall pay promptly upon
receipt. Landlord shall not be liable



                                      -9-
<PAGE>


to Tenant for damages or otherwise for any interruption, curtailment or
suspension of any or all utility services in the event of a default by Tenant
under this Lease, or due to repairs, action of public authority, strikes, acts
of God or public enemy, or any other cause, whether similar or dissimilar to the
foregoing.

SECTION 7.02 Application for Utilities. If Landlord shall elect not to supply or
shall elect to discontinue supplying Tenant with any utilities, Tenant, at
Tenant's sole expense, shall promptly make all appropriate arrangements with the
local utility companies for the hookup and supply of such utilities to the
Premises, including, without limitation, any metering expense and installation
costs. Landlord shall supply water to the Premises and Tenant shall pay for its
usage on a monthly basis based on a separate meter.

Article V, Landlord shall keep the roof and the exterior walls of the Premises
in proper repair; provided, however, if Landlord is required to make such
repairs by reason of Tenant's negligence or breach of this Lease, Landlord may
collect the cost of such repairs from Tenant upon demand. If, without Landlord's
consent, Tenant performs any alterations or improvements which affect the roof
or exterior walls, such action by Tenant shall release Landlord from its repair
obligation and Tenant shall thereafter be responsible for the maintenance of the
roof and exterior walls so affected, provided, however, nothing herein contained
shall be construed to grant Tenant the right to perform any alterations or
improvements which affect the roof or exterior walls. Except as herein provided,
Landlord shall have no obligation to repair or maintain the Premises, including,

damage to the Premises caused by any construction or alterations performed by
Tenant, or by the delivery, installation or removal of Tenant's property, or by
Tenant's negligence.

SECTION 8.03 Tenant's Right to Make Alterations. Tenant shall not make any
alterations, improvements or additions to the Premises without the prior written
consent of Landlord, which Landlord will not unreasonably withhold. Tenant shall
supply Landlord with plans and specifications for all such alterations,
improvements and additions prior to requesting such consent. All alterations,
improvements and additions made by Tenant shall remain upon the



                                      -10-
<PAGE>


Premises at the expiration or earlier termination of this Lease and shall become
the property of Landlord unless Landlord shall, prior to the commencement of
work on such alterations, improvements or additions, have given written notice
to Tenant to remove same, in which event Tenant shall remove such alterations,
improvements and additions and restore the Premises to the same good order and
condition in which it was on the date of this Lease except for any Landlord's
Work. Should Tenant fail so to do, Landlord may do so, and Tenant shall
reimburse Landlord for Landlord's expenses, on demand. All of such alterations,
improvements or additions shall be made solely at Tenant's expense; and Tenant
agrees to indemnify and save harmless Landlord (a) on account of any injury to
third persons or property by reason of any such changes, additions or
alterations and (b) from the payment of any claim on account of bills for labor
or materials furnished or claimed to have been furnished in connection
therewith. Tenant agrees to procure all necessary permits before undertaking
such work and to do all such work in a good and workmanlike manner, employing
materials of first quality and complying with all applicable governmental
requirements.

SECTION 9.01 Tenant Shall Discharge All Liens. Tenant shall promptly pay all
contractors and materialmen retained by Tenant so as to minimize the possibility
of a mechanic's or materialman's lien attaching to the Premises or the Building.
Should any such lien be made or filed, Tenant shall bond against or discharge
the same within ten (10) days after written request by Landlord and, in the
event that Tenant shall fail to do so, Landlord, in addition to its other
remedies, may discharge the lien by payment of the amount secured thereby, or
otherwise as provided by law, and any amount so paid by Landlord, together with
any attorney's fees or other costs relating to the discharge of such lien, shall
be immediately payable by Tenant to Landlord. Prior to the commencement of any
work or the delivery of any material to the Premises by any contractor,
subcontractor or materialman ("Contractor"), Tenant shall deliver to Landlord a
recordable waiver of liens from each such Contractor in form and content
reasonably acceptable to Landlord. Prior to opening the Premises for business
with the public, Tenant shall deliver to Landlord a release of liens from each
such Contractor in form and content reasonably acceptable to Landlord.

however, that nothing herein contained shall be deemed or construed as an
obligation of Landlord to undertake or effect any such repairs, alterations or
additions other than as herein specifically set forth, and any performance

or walks; (iii) fire, explosion, collapse or broken glass; (iv) the backing up
of any sewer pipe or downspout; (v) the bursting, leaking or running of any
tank, tub, washstand, water closet, waste pipe, drain or any other pipe or tank
in, upon or about the Premises or the Building; (vi) the escape of steam or hot
water; (vii) water, snow, or ice being upon or coming through the roof,
skylight, trap door, stairs, doorways, show windows, walks or any other place
upon or near the Premises or the Building or otherwise; (viii) the falling of
any fixture, plaster, tile or stucco; and (ix) any act, omission or negligence
of other tenants, licensees or of any other persons or occupants of the
Building, or of owners of adjacent or contiguous property, or the public, unless
such damage arises from Landlord's negligence or willful misconduct or
Landlord's breach of this Lease.

SECTION 12.04 Litigation Involving Landlord. In the event that Landlord shall be
made a party to any litigation commenced against Tenant by a third party not
arising from Landlord's negligence or misconduct, Tenant shall indemnify and
hold harmless Landlord from and against any liability arising therefrom, and
shall pay all costs, expenses and reasonable attorneys' fees.


                                  ARTICLE XIII

                                    INSURANCE

SECTION 13.01 Required Coverages. Tenant, at Tenant's sole expense, shall obtain
and maintain in full force and effect during the term of this Lease, the
following policies of insurance:

                        (a) Fire and extended coverage insurance covering all of
Tenant's stock in trade, fixtures, furniture, furnishings, and all other
improvements and decorations placed


                                      -13-
<PAGE>


by Tenant in or upon the Premises, to the extent of 100% of their full insurable
value and replacement cost without deduction for depreciation;

                        (b) Comprehensive general public liability insurance on
an occurrence basis with minimum limits of liability in an amount of not less
than $1,000,000.00 for bodily, personal injury or death to any one person, not
less than $1,000,000.00 for bodily, personal injury or death to more than one
person and not less than $500,000.00 with respect to damage to property
including water damage and sprinkler leakage legal liability;

                        (c) Plate glass insurance covering all plate glass in
the Premises.

SECTION 13.02 Designated Insureds; Endorsements; Evidence of Insurance. All
insurance policies to be obtained by Tenant hereunder shall be in the names of
both Landlord and Tenant, as their respective interests may appear, together
with such other party or parties as may be designated by Landlord, including,
without limitation, Landlord's mortgagees, as their interests may appear. All
such policies of insurance shall be issued by financially responsible companies
licensed to do business in Pennsylvania, and shall contain endorsements
providing as follows: (a) that any such insurance shall not be subject to
cancellation, termination or change except after ten (10) days' prior written
notice by registered or certified mail to Landlord and such party or parties as
may be designated by Landlord (collectively "Landlord's Group") by the insurance
company; and (b) that Landlord's Group shall not be liable for any damage by
fire or other casualty covered by such insurance, it being understood that
Tenant shall look solely to its insurer or insurers for reimbursement. Tenant
waives its right to recover damages against Landlord's Group for any reason
whatsoever to the extent the damage or destruction is covered by such insurance.
Any insurance policy procured by Tenant which does not name all the members of
Landlord's Group as additional insureds shall contain an express waiver of any
right of subrogation by the insurance company against Landlord's Group. All
public liability and property damage policies shall contain an endorsement that
the members of Landlord's Group, although named as insureds, shall nevertheless
be entitled to recover under said policies for any loss or damage occasioned to
them, their servants, agents and employees by reason of the negligence of
Tenant. All policies of fire and/or extended coverage or other insurance
covering the Premises or its contents shall contain a clause or endorsement
providing in substance that the insurance shall not be prejudiced if the
insureds have waived right of recovery from any person or persons prior to the
date and time of loss or damage, if any. All policies shall contain a provision
substantially as follows: "The insurance afforded by this policy for more than
one named insured shall not operate to increase the limits of the company's
liability, but otherwise, shall not operate to limit or void the coverage of any
one named insured as respects claims against the same insured by any other named
insured or the employees of such other named insured". The original policy or
policies, or duly executed certificates for the same, together with satisfactory
evidence of payment of the premium thereof shall be delivered to Landlord's
Group upon the execution of this Lease, and upon renewals of such policies, not
less than fifteen (15) days prior to the expiration of the term of any such
coverage.

SECTION 13.03 No Injurious Acts. Tenant shall not do or keep anything in or
about the Premises which will violate the provisions of Landlord's insurance
policies, or which will


                                      -14-
<PAGE>


adversely affect Landlord's fire or liability insurance premium rating or which
will prevent Landlord from procuring and maintaining such policies with
insurance companies acceptable to Landlord. If anything is done, omitted to be
done or kept by Tenant in or about the Premises which causes the rate of any
insurance on the Premises or other property of Landlord in companies acceptable
to Landlord to be increased, Tenant will pay the amount of such increase
promptly upon Landlord's demand (provided that any other tenant of the Building
whose acts or omissions increase the insurance premiums of the Building shall
likewise be solely responsible for such increases).

SECTION 13.04 Failure to Maintain Required Coverage. In the event that Tenant
shall fail to obtain or maintain in full force and effect the insurance policies
and coverages required of it hereunder, Landlord may obtain such insurance or
coverage, pay the premiums thereon, and take such other steps as may be
necessary to meet the requirements of this Article and upon demand, obtain
reimbursement of the costs so expended (including service charges in the amount
of 1-1/2% per month upon all such costs paid by Landlord) from Tenant.


                                   ARTICLE XIV

                                 TRADE FIXTURES

SECTION 14.01 Title to Property and Removal. All trade fixtures (including,
without limitation, hoods, equipment, tanks and other items to be placed in the
"clean room" and designated as trade fixtures by Tenant) installed by Tenant in
the Premises shall remain the property of Tenant and shall be removable at the
expiration or earlier termination of this Lease, provided Tenant shall not at
such time be in default under this Lease; and provided further, that in the
event of such removal, Tenant shall repair any damage caused by such removal,
and Tenant shall promptly restore the Premises to its original order and
condition, normal wear and tear excepted. Any such trade fixture not removed at
or prior to such termination shall be and become the property of Landlord.
Subject to the foregoing, lighting fixtures and air conditioning equipment,
whether or not installed by Tenant, shall not be removable at the expiration or
earlier termination of this Lease and shall become the property of Landlord.

SECTION 14.02 Failure to Remove. In the event, at the expiration or earlier
termination of this Lease, Tenant fails to remove any trade fixtures installed
by Tenant, then Landlord may remove such fixtures and recover all costs
incidental to such removal from Tenant, and Landlord may dispose of such
fixtures in any manner Landlord deems fit without the necessity of accounting to
Tenant for the proceeds of same.

                            ASSIGNMENT AND SUBLETTING

SECTION 15.01 Landlord's Consent. Tenant shall not voluntarily, involuntarily or
by operation of law assign, mortgage, pledge or encumber (collectively
"Assignment") this Lease, in whole or in part, or sublet the whole or any part
of the Premises, or permit the use or occupancy of the whole or any part of the
Premises by others, including, without limitation, the operation of all or any
part of the Premises by a licensee or concessionaire, without first obtaining in
each and every instance the prior written consent of Landlord, which Landlord
will not unreasonably withhold. Such consent shall be based on, inter alia, the
net worth of the proposed assignee/subtenant, the proposed use and the rent to
be paid. Landlord will consent to a sublease or assignment to an affiliate or
subsidiary of Tenant so long as the overall lease credit is not impaired. Any
consent by Landlord to an Assignment or subletting or use or occupancy by others
shall be held to apply only to the specific transaction thereby authorized and
shall not constitute a waiver of the necessity for such consent to any
subsequent assignment or subletting or use or occupancy by others. If this Lease
or any interest herein be assigned or if the Premises or any part thereof be
sublet or used or occupied by anyone other than Tenant with Landlord's prior
written consent, Tenant shall pay to Landlord monthly the excess of the
consideration received or to be received during such month for such Assignment,
sublease, or occupancy (whether or not denoted as rent) over the rent reserved
for such month in this Lease applicable to such portion of the Premises so
assigned, sublet or occupied, after deduction of Tenant's reasonable expenses.
If this Lease or any interest of Tenant herein be assigned or if the whole or
any part of the Premises be sublet or used or occupied by others (including,
without limitation, an affiliate or subsidiary of Tenant), after having obtained
Landlord's prior written consent thereto, Tenant shall nevertheless remain fully
liable for the full performance of all obligations under this Lease to be
performed by Tenant and Tenant shall not be released therefrom in any manner.

SECTION 15.02 Transfers of Corporate and Partnership Interests. If Tenant is a
corporation, the transfer at any time during the term of this Lease of part or
all of the corporate shares of Tenant, or of a parent corporation of which
Tenant is a direct or indirect subsidiary, which results, either individually or
cumulatively, in a change in the effective voting control of Tenant or of such
parent corporation shall constitute a prohibited assignment of this Lease;
provided however that (i) Landlord shall not unreasonably withhold its consent
to such a transfer if the transferee demonstrates to Landlord's satisfaction a
net worth greater than the net worth of the transferor on the date of this
Lease, and (ii) this provision shall not apply in the event that over fifty
percent (50%) of the voting power of the Tenant corporation or of such parent
corporation is held by fifty (50) or more unrelated shareholders. If Tenant is a
partnership, and if at any time during the term of this Lease any person who at
the time of the execution of this Lease owns a general partner's interest ceases
to own such general partner's interest, such cessation of ownership shall
constitute a prohibited Assignment of this Lease.

                          SUBORDINATION AND ATTORNMENT

SECTION 16.01 Mortgages. This Lease and the Tenant's interest hereunder shall be
subject and subordinate at all times to any and all mortgages, deeds of trust,
and other security instruments, including all renewals, extensions,
consolidations, assignments and refinancings of the same (collectively
"Mortgage") as well as all advances made upon the security thereof, which now or
hereafter become liens upon the Landlord's interest in the Premises and/or the
Building. Notwithstanding the foregoing, so long as no Event of Default has
occurred hereunder, Tenant shall not be disturbed in its quiet enjoyment of the
Premises. In case Landlord's interest under the Mortgage shall terminate for any
reason and if the holder of any such Mortgage ("Mortgagee") or if the grantee of
a deed in lieu of foreclosure, or if the purchaser at any foreclosure sale or at
any sale under a power of sale contained in any such Mortgage shall at its sole
option so request, Tenant shall attorn to, and recognize such Mortgagee, grantee
or purchaser, as the case may be, as Landlord under this Lease for the balance
then remaining of the term of this Lease, subject to all terms of this Lease.
The aforesaid provisions shall be self-operative and no further instrument or
document shall be necessary unless required by any such Mortgagee, grantee or
purchaser. Notwithstanding anything to the contrary set forth above, any
Mortgagee may at any time subordinate its Mortgage to this Lease, without
Tenant's consent, by execution of a written document subordinating such Mortgage
to this Lease, and thereupon this Lease shall be deemed prior to such Mortgage.

SECTION 16.02 Execution of Documents. Tenant agrees to execute such documents as
may be required by any such Mortgagee, grantee or purchaser for the purpose of
confirming such subordination or attornment. In the event Tenant fails to
execute such documents within ten (10) days after a written request therefor
shall have been forwarded to Tenant by Landlord, then Tenant shall be deemed to
have appointed Landlord, and Landlord shall thereupon be regarded as the
irrevocable attorney-in-fact of the Tenant, duly authorized to execute and
deliver the required documents for and on behalf of Tenant.


                                  ARTICLE XVII

                             SURRENDER AND HOLDOVER

SECTION 17.01 Tenant's Obligation to Surrender Premises. Tenant, upon expiration
or earlier termination of this Lease, shall peaceably surrender to Landlord the
Premises in broom-clean condition and in good repair as required by the terms of
this Lease subject to reasonable wear and tear. Tenant shall surrender all keys
for the Premises to Landlord. Tenant shall remove all trade fixtures before
surrendering the Premises as aforesaid and shall repair any damage to the
Premises caused thereby.


                                      -17-
<PAGE>

SECTION 17.02 Consensual Holdover. In the event Tenant shall remain in
possession of the Premises with Landlord's consent but without having executed a
new lease or an extension or renewal of this Lease, then Tenant shall be deemed
to be in occupancy and possession of the Premises as a tenant from month to
month, subject to all the other terms and conditions of this Lease insofar as
the same are applicable to a month-to-month tenancy. In the event that there
occurs such a consensual holdover, either party may terminate said occupancy at
the end of any one month period following the expiration date of the term of
this Lease upon at least thirty (30) days' written notice to the other party.

SECTION 17.03 Tenant's Liability for Failure to Surrender. If Tenant fails to so
surrender the Premises upon the expiration or earlier termination of this Lease,
Tenant shall pay, for the period Tenant retains possession of the Premises, an
amount equal to 150% of the Fixed Minimum Rent and other charges payable
immediately prior to the expiration or earlier termination of this Lease, and
Tenant shall indemnify and hold harmless Landlord from loss or liability
resulting from such failure including, without limitation, any claims made by
any succeeding tenant founded on such failure. Nothing contained in this section
shall be deemed or construed as conferring upon Tenant a right to remain in
possession of the Premises beyond the expiration or termination of this Lease or
any extension or renewal hereof.


                                  ARTICLE XVIII

                        DAMAGE OR DESTRUCTION OF PREMISES

SECTION 18.01 Total or Partial Destruction. If the Premises shall be damaged by
fire or other casualty covered by Landlord's policies of fire and broad form
extended coverage insurance but are not thereby rendered untenantable in whole
or in part, Landlord shall at its own expense cause such damage to be repaired,
and the rent shall not be abated. If by reason of such occurrence, the Premises
shall be rendered untenantable in whole or in part and such damage can, in
Landlord's reasonable judgment, be repaired within 180 days, Landlord shall at
its own expense cause the damage to be repaired and the Fixed Minimum Rent and
other charges due hereunder meanwhile shall be abated proportionately as to the
portion of the Premises rendered untenantable until Landlord has restored the
Premises. If the Premises shall be damaged or destroyed by a fire or casualty
not covered by Landlord's policies of fire and broad form extended coverage
insurance and Landlord decides not to repair and restore the Premises, Landlord
shall have the right, to be exercised by notice in writing delivered to Tenant
within ninety (90) days from and after the occurrence of such damage or
destruction, to elect to terminate this Lease. Landlord shall have the right, to
be exercised by notice in writing, delivered to Tenant within thirty (30) days
after any occurrence which renders the Premises wholly untenantable to terminate
this Lease if said destruction of the Premises occurs within the last three (3)
years of the original term or the last three (3) years of any renewal term
hereof. In any of said events, the termination shall take effect thirty (30)
days after the receipt of such notice by Tenant and the rent and other charges
shall be payable through such date, subject to proportional abatement. In no
event shall Landlord be obligated to expend for any repairs or reconstruction an
amount in excess of the insurance proceeds recovered by it and allocable to the



                                      -18-
<PAGE>



damage of the Premises after deduction therefrom of any amounts required to be
paid to any Mortgagee. Landlord shall not be liable for delays occasioned by
adjustment of losses with insurance carriers or by any other cause so long as
Landlord shall proceed in good faith. If Landlord is required to repair or
reconstruct the Premises pursuant to the provisions of this section, Landlord's
obligation shall be limited to the construction of the Building shell. Tenant,
at Tenant's expense, shall submit to Landlord for Landlord's approval plans and
specifications for all other work not required to be done by Landlord and, upon
approval of such plans and specifications and within fifteen (15) days after
Tenant has been notified that Landlord has completed its work on the Premises,
Tenant shall reenter the Premises and therein diligently pursue to completion
such work at Tenant's expense and thereafter commence doing business all in
accordance with the provisions of this Lease within forty-five (45) days after
said notice.

SECTION 18.02 Partial Destruction of Building. In the event that more than one
third (1/3) of the gross leasable area of the Building shall be damaged or
destroyed by fire or other cause, notwithstanding that the Premises may be
unaffected by such fire or other cause, Landlord shall have the right, to be
exercised by notice in writing delivered to Tenant within sixty (60) days after
said occurrence, to terminate this Lease. Upon the giving of such notice, the
term of this Lease shall expire fifteen (15) days after such notice is given,
the rent and other charges shall be payable through such date, subject to
proportional abatement, and Tenant shall vacate the Premises and surrender the
same to Landlord.

SECTION 18.03 Notice by Tenant. Tenant shall immediately notify Landlord of any
damage by fire or other casualty to the Premises or to the Building.


                                   ARTICLE XIX

                                 EMINENT DOMAIN

SECTION 19.01 Total Condemnation. If the whole of the Premises shall be taken by
any public or quasi-public authority under the power of eminent domain,
condemnation or expropriation or in the event of a conveyance in lieu thereof,
then the term of this Lease shall terminate as of the date on which possession
of the Premises is required to be surrendered to the condemning authority, all
rent and other charges shall be paid up to that date, and Tenant shall have no
claim against Landlord for the value of any unexpired term of this Lease.

SECTION 19.02 Partial Condemnation. If any part of the Premises shall be so
taken or conveyed, and in the event that such partial taking or conveyance shall
render the Premises unsuitable for the business of Tenant in Tenant's , then the
term of this Lease shall terminate as of the date on which possession of the
Premises is required to be surrendered to the condemning authority, all rent and
other charges shall be paid up to that date, and Tenant shall have no claim
against Landlord for the value of any unexpired term of this Lease. In the event
of a partial taking or conveyance which is not extensive enough to render the
Premises unsuitable for the business of Tenant, then Landlord shall promptly
restore the Premises to the extent of condemnation proceeds available for such
purpose to a condition comparable to their condition at


                                      -19-
<PAGE>



the time of such condemnation less the portion lost in the taking, Tenant shall
promptly make all necessary repairs, restoration and alterations of Tenant's
fixtures, equipment and furnishings and shall promptly reenter the Premises and
commence doing business in accordance with the provisions of this Lease and this
Lease shall continue in full force and effect. In such event, the Fixed Minimum
Rent shall be reduced in the same proportion that the floor area of the Premises
so taken or conveyed bears to the floor area of the Premises immediately prior
to such taking or conveyance, such reduction commencing as of the date Tenant is
required to surrender possession of such portion. For purposes of determining
the amount of funds available for restoration of the Premises from the
condemnation award, said amount shall be deemed to be that part of the award
which remains after payment of Landlord's reasonable expenses incurred in
recovering same and any amounts due to any Mortgagee, and which represents a
portion of the total sum so available (excluding any award or other compensation
for land) which is equitably allocable to the Premises.

SECTION 19.03 Partial Condemnation of Building. If (a) more than one third (1/3)
of the floor area of the Building or more than one third (1/3) of the Common
Areas shall be so taken or conveyed, or (b) any part of the parking area in the
Building shall be so taken or conveyed and if, as the result of such partial
taking or conveyance of the parking area, the size, layout or location of the
remaining parking facilities shall violate the requirements of the applicable
zoning or similar laws, then Landlord shall have the right to terminate this
Lease as of the date on which possession of the property is required to be
surrendered to the condemning authority, and all rent and other charges shall be
paid up to that date. Tenant shall have no claim against Landlord for the value
of any unexpired term of this Lease.

SECTION 19.04 Landlord's Damages. In the event of any taking or conveyance as
herein provided, Tenant shall not be entitled to any part of the award for such
taking or conveyance, and Landlord and any Mortgagee shall receive the full
amount of such award as their respective interests may appear. Tenant expressly
waives any right or claim to any part thereof and assigns to Landlord any such
right or claim to which Tenant might become entitled.

SECTION 19.05 Tenant's Damages. Although all damages in the event of any
condemnation shall belong to Landlord and any Mortgagee, Tenant shall have the
right, to the extent that same shall not diminish Landlord's or such Mortgagee's
award, to claim and recover from the condemning authority, but not from Landlord
or such Mortgagee, such compensation as may be separately awarded or recoverable
by Tenant in Tenant's own right for or on account of, and limited solely to, any
cost to which Tenant might be put in removing Tenant's merchandise, furniture,
fixtures, leasehold improvements and equipment.

                                TENANT'S DEFAULT

SECTION 20.01 Events of Default. Each of the following shall constitute an Event
of Default ("Event of Default"):



                                      -20-
<PAGE>

                  (a) Tenant defaults in the payment of any installment of Fixed
Minimum Rent for a period of ten (10) days after such payment is due. Landlord
shall give Tenant three days' notice of such default before any exercising any
remedy, but shall not be obligated to give such notice more than twice in any
12-month period and thereafter may exercise Landlord's remedies without any
notice; or

                  (b) Tenant defaults in the payment of any installment of, or
on account of, Tax Rent, Tenant's Pro Rata Share of Operating Costs or any other
charge or payment due or payable by Tenant under this Lease on any day upon
which the same shall be due and payable and such default continues for ten (10)
days after the date on which the same was due and payable; or

                  (c) Tenant defaults in the performance of any obligation,
covenant or agreement of Tenant to be performed or observed under this Lease,
other than those specifically set forth elsewhere in this Section 20.01, and
such default continues and is not cured by Tenant within thirty (30) days after
Landlord has given to Tenant a notice specifying the same, or, in the case of a
default which cannot with due diligence be cured within a period of thirty (30)
days and the continuance of which for the period required for cure will not
subject Landlord to the risk of criminal liability or termination of any
superior lease or foreclosure of any Mortgage, if Tenant does not in good faith
duly institute within such thirty (30) day period all steps necessary to cure
the same and promptly and diligently prosecute to completion such cure within
ninety (90) days after said Landlord's notice, provided however that, in the
event there are defaults under this Section 20.01(c) on two occasions within any
twelve (12) month period, then regardless of whether said defaults shall have
been cured within the applicable period set forth above, any further default
under this Section 20.01(c) shall be deemed a "Deliberate Event of Default". In
the event of a Deliberate Event of Default, Landlord, without giving Tenant any
notice or opportunity to cure such default, may exercise all of Landlord's
rights under this Lease, at law, in equity or otherwise; or

                  (d) Tenant abandons the Premises, whether the Premises are
vacant or not, or Tenant permits the Premises to be vacant; or

                  (e) Tenant removes, attempts to remove or expresses or
displays any intention to remove any of the goods or property in the Premises
other than in the ordinary and usual course of business; or

                  (f) Any execution or attachment is issued against Tenant or
any of Tenant's property and is not discharged or vacated within thirty (30)
days after the issuance thereof; or

                  (g) Tenant is in breach of the terms of Article XV of this
Lease; or

                  (h) Tenant or any guarantor of Tenant makes an assignment for
the benefit of creditors or becomes a party or subject to any liquidation or
dissolution action or proceeding, or the institution of any bankruptcy,
reorganization, insolvency or other proceeding for the relief of financially
distressed debtors with respect to Tenant or said guarantor, or the appointment
of a receiver, liquidator, custodian or trustee for Tenant or said guarantor or
a substantial part of


                                      -21-
<PAGE>


Tenant's or said guarantor's assets and, if any of the same shall occur
involuntarily, the same is not dismissed or discharged within sixty (60) days;
or the entry of an order for relief against Tenant or said guarantor under Title
II of the United States Code entitled "Bankruptcy"; or Tenant or said guarantor
taking any action to effect, or which indicates Tenant's or said guarantor's
acquiescence in, any of the foregoing.


                                   ARTICLE XXI

                   REMEDIES OF LANDLORD UPON TENANT'S DEFAULT

SECTION 21.01 Acceleration of Rent. Upon the occurrence of an Event of Default,
the entire rent and all other sums payable hereunder for the balance of the term
shall immediately become due and payable as if by the terms of this Lease they
were payable in advance, and Landlord may immediately proceed to distrain,
collect, confess judgment or bring action for said rent and other sums, as being
in arrears, or may file a proof of claim in any bankruptcy or insolvency
proceedings for such rent and other sums, or Landlord may institute any other
proceedings to enforce payment thereof.

         For the purposes of this Section 21.01, the rent and all other sums
payable hereunder for the balance of the term shall be deemed to be the sum of
(a) the aggregate of the Fixed Minimum Rent reserved for the balance of the term
of this Lease and (b) the annual average of the Tax Rent, Tenant's Pro Rata
Share of Operating Costs, Tenant's utility charges and other charges payable in
the Lease Year immediately preceding the Event of Default (collectively "Annual
Lease Payments") multiplied by the number of years and fraction of a year then
constituting the unexpired term of this Lease (in each case exclusive of
unexercised renewal periods).

SECTION 21.02 Right to Reenter. Upon the occurrence of an Event of Default,
Landlord may terminate all services (including, without limitation, the
furnishing of utilities) and may reenter the Premises, either by summary
proceeding or otherwise, and may remove all persons and property from the
Premises, and such property may be removed and stored in public warehouse at the
cost of and for the account of Tenant. Landlord, without further demand or
notice, may proceed to distress and sell the goods there found and to levy the
rent and all other charges herein, and Tenant shall pay all costs and officers'
commissions, including watchmen's wage, and further including a sum equal to
five percent (5%) of the amount of the levy chargeable as commissions to the
constable or other person making the levy and, in such cases, all costs,
officers' commissions and other charges shall immediately attach and become a
part of the claim of Landlord for rent, and any tender of rent without said
costs, commissions and charges made after the issue of a warrant of distress
shall not be sufficient to satisfy the claim of Landlord.

SECTION 21.03 Right to Relet; Damages for Breach. Should Landlord elect to
reenter the Premises as herein provided, or should Landlord take possession
pursuant to legal proceedings or pursuant to any notice provided for by law,
Landlord may relet the Premises or any part thereof for such term or terms
(which may be for a term extending beyond the term of this Lease) and at


                                      -22-
<PAGE>


such rental or rentals and upon such other terms and conditions as Landlord in
its sole discretion may deem advisable; Landlord may make such alterations and
repairs as Landlord deems necessary in order to relet the Premises; upon each
such reletting all rentals received by Landlord from such reletting shall be
applied, first, to the payment of any costs and expenses of such reletting,
including brokerage fees, attorneys' fees and costs of such alterations and
repairs; second, to the payment of any indebtedness other than rent due
hereunder from Tenant to Landlord; third, to the payment of rent due and unpaid
hereunder; and the residue, if any, shall be held by Landlord and applied in
payment of future rent as the same may become due and payable hereunder. If such
rents received from such reletting during any month are less than that to be
paid during that month by Tenant hereunder, Tenant shall pay any such deficiency
to Landlord. Such deficiency shall be calculated and paid monthly. No such
reentry or taking possession of the Premises by Landlord shall be construed as
an election on its part to terminate this Lease unless a written notice of such
intention be given to Tenant or unless the termination thereof be decreed by a
court of competent jurisdiction. Notwithstanding any such reletting without
termination, Landlord may at any time thereafter elect to terminate this Lease
for such previous breach.

SECTION 21.04 Right to Terminate; Right to Discontinue Services. Upon the
occurrence of an Event of Default, Landlord may give Tenant a notice of
intention to end the term of this Lease at the expiration of five (5) days from
the service of such notice of intention, and upon the expiration of said five
(5) day period, this Lease (whether or not the term hereof shall theretofore
have commenced), as well as all of the right, title and interest of Tenant
hereunder, shall wholly cease and expire and become void (except as to Tenant's
liability) in the same manner and with the same force and effect as if the date
fixed in such notice were the date herein originally specified for the
expiration of the term hereof; and Tenant shall then immediately quit and
surrender to Landlord the Premises, and Landlord may enter into and repossess
the Premises by summary proceedings, detainer, ejectment or otherwise and remove
all occupants thereof and, at Landlord's option, any property thereon, without
being liable to indictment, prosecution or damage therefor. Tenant shall not
have the right to prevent said termination by payment of any sum due or the
performance of any other obligations under this Lease.

SECTION 21.05 Confession of Judgment. THE FOLLOWING PARAGRAPHS SET FORTH
WARRANTS OF AUTHORITY FOR AN ATTORNEY TO CONFESS JUDGMENTS AGAINST TENANT. IN
GRANTING THESE WARRANTS OF ATTORNEY TO CONFESS JUDGMENTS AGAINST TENANT, TENANT
HEREBY KNOWINGLY, INTENTIONALLY AND VOLUNTARILY, AND, ON THE ADVICE OF THE
SEPARATE COUNSEL OF TENANT, UNCONDITIONALLY WAIVES ANY AND ALL RIGHTS TENANT HAS
OR MAY HAVE WITH RESPECT TO PRIOR NOTICE AND AN OPPORTUNITY FOR HEARING UNDER
THE RESPECTIVE CONSTITUTIONS AND LAWS OF THE UNITED STATES AND THE COMMONWEALTH
OF PENNSYLVANIA.

                  21.05.1 Upon the occurrence of an Event of Default, Tenant
hereby empowers any Prothonotary or attorney of any court of record to appear
for Tenant in any and all actions which may be brought for rent and/or any other
sums due hereunder by Tenant, and to


                                      -23-
<PAGE>


confess judgment against Tenant for all or any part of the rent and/or such
other sums, including, at Landlord's option, the rent and/or such other sums for
the entire unexpired balance of the term of this Lease, and for interest and
costs, together with an attorneys' commission of five percent (5%), but without
deduction therefrom for the fair rental value of the Premises. Such authority
shall not be exhausted by one exercise thereof, but judgment may be confessed as
aforesaid from time to time and as often as there is an occurrence of an Event
of Default, and such powers may be exercised during the original term, any
extension or renewal term, and after the expiration of any such term.

                  21.05.2 Upon (a) the occurrence of an Event of Default, or (b)
the termination of this Lease during the original term hereof or any renewal or
extension thereof on account of any default by Tenant hereunder, or (c) upon the
expiration of the original term of this Lease or any renewal or extension
thereof, it shall be lawful for any Prothonotary or attorney of any court of
record to appear for Tenant as well as for all persons claiming by, through or
under Tenant, to confess judgment in ejectment, without any stay of execution or
appeal, against Tenant and all persons claiming by, through or under Tenant for
the recovery by Landlord of possession of the Premises, without any liability on
the part of the such attorney, for which this Lease or a true and correct copy
thereof shall be a sufficient warrant; whereupon, if Landlord so desires, a writ
of possession may issue forthwith, without any prior writ or proceedings
whatsoever. If for any reason after such action has been commenced, the same
shall be determined and the possession of the Premises remain in or be restored
to Tenant, Landlord shall have the right upon any subsequent Event(s) of
Default, or upon the termination or expiration of this Lease or of Tenant's
right of possession as herein set forth, to confess judgment from time to time
in the manner and form herein set forth to recover possession of the Premises.
No such determination of this Lease, no taking, nor recovering possession of the
Premises shall deprive Landlord of any remedies or action against Tenant for
rent or for damages due or to become due for Tenant's breach of this Lease, nor
shall the bringing of any such action for rent, or breach of covenant or
condition nor the resort to any other remedy herein provided for the recovery of
rent or damages for such breach be construed as a waiver of the right to insist
upon the forfeiture and to obtain possession in the manner herein provided.

                  21.05.3 In any action of ejectment or for rent in arrears,
Landlord shall first cause to be filed in such action an affidavit made by it or
someone acting for it setting forth the facts necessary to authorize the entry
of judgment, of which facts such affidavit shall be conclusive evidence, and, if
a true copy of this Lease be filed in such action, it shall not be necessary to
file the original as a warrant of attorney, any rule of court, custom or
practice to the contrary notwithstanding.

                  21.05.4 The right to enter judgment against Tenant by
confession and to enforce all of the other provisions of this Lease herein
provided for may, at the option of any assignee of this Lease, be exercised by
any assignee of Landlord's right, title and interest in this Lease in said
assignee's name, any statute, rule of court, custom or practice to the contrary
notwithstanding.


                                      -24-

SECTION 21.06 Recovery of Legal Expenses. In the event Landlord shall engage the
services of an attorney for recovery of possession of the Premises, for the
recovery of rent or any other amount due under this Lease, or because of
Tenant's breach of any of the terms hereof, regardless of whether suit shall be
brought, and a breach shall be established, Tenant shall pay to Landlord all
reasonable expenses incurred therefor, including all court costs and reasonable
attorneys' fees.

SECTION 21.07 Injunctive Relief; All Remedies Cumulative. In the event of a
breach by Tenant of any of the terms hereof, Landlord shall have the right to
injunctive relief to restrain Tenant and the right to invoke any remedy allowed
by law or in equity whether or not other remedies are herein provided. Each
right and remedy of Landlord provided for in this Lease shall be cumulative and
shall be in addition to every other right or remedy provided for in this Lease
or now or hereafter existing at law, in equity, by statute or otherwise, and the
exercise of any one or more of such rights and remedies shall not preclude the
simultaneous or later exercise of any or all other such rights and remedies.

Tenant has had no dealing, negotiations or consultations with respect to the
Premises, the Building or this transaction with any broker or finder except as
disclosed in the Lease Summary and that no other broker or finder called the

to have submitted the Premises or any other space in the Building to Tenant, to
have induced Tenant to lease the Premises or to have taken part in any dealings,
negotiations or consultations with respect to the Premises, the Building or this

                                  MISCELLANEOUS

SECTION 25.01 Binding Effect. All rights, obligations and liabilities herein
given to or imposed upon the respective parties hereto shall extend to and bind
the several respective heirs, personal representatives, successors and assigns
of the said parties; and if there shall be more than one Tenant, they shall all

<PAGE>


hindrance or interruption by Landlord or any other person or persons lawfully
claiming by, through or under Landlord, subject, nevertheless, to the terms and
conditions of this Lease.

SECTION 25.03 Waiver. The waiver by Landlord of any breach of any term, covenant
or condition herein contained shall not be deemed to be a waiver of any

condition herein contained. No covenant, term or condition of this Lease shall
be deemed to have been waived by Landlord, unless such waiver be in writing and
executed by Landlord.

SECTION 25.04 Custom and Usage. Landlord shall have the right at all times to
enforce the covenants and conditions of this Lease in strict accordance with the
terms hereof, notwithstanding any conduct or custom on the part of Landlord in
refraining from so doing at any time or times with respect to Tenant hereunder
or with respect to other tenants of the Building. The failure of Landlord at any
time or times to enforce its rights under said covenants and provisions strictly

this Lease or as having in any way or manner modified the same.

Landlord of a lesser amount than any payment of rent or other charges herein
stipulated shall be deemed to be other than on account of the earliest
stipulated rent or other charges then due and payable. Landlord shall not be
bound by any endorsement or statement on any check or any letter accompanying
any check or payment and no such endorsement, statement or letter shall be
deemed an accord and satisfaction. Landlord may accept such check or payment
without prejudice to Landlord's right to recover the balance of such rent or
other charges or pursue any other remedy.

Exhibits, set forth all the agreements and understandings between Landlord and
Tenant concerning the Premises and there are no agreements or understandings,
either oral or written, between them other than as herein set forth. All prior
arrangements and understandings, whether oral or written, between the parties

the same. No amendment to this Lease shall be binding upon Landlord or Tenant
unless reduced to writing and executed by the party against which such amendment
is to be enforced.

subject to levy, execution or other judicial process for the satisfaction of
Tenant's claim

docket shall be so noted. In the event of any sale of the Premises or the
Building, Landlord shall be and hereby is entirely freed and relieved of all
obligations of Landlord hereunder. This section shall inure to the benefit of
Landlord and Landlord's successors and assigns and their respective principals.

SECTION 25.09 Partial Invalidity; Separate Covenants. If any portion of this
Lease or the application thereof to any person or circumstances shall be invalid
or unenforceable, the remainder of this Lease and the application of such
portion to persons or circumstances other than those as to which it is held
invalid or unenforceable shall not be affected thereby, and each term, covenant
and condition of this Lease shall be valid and be enforced to the fullest extent
permitted by law. Furthermore, each covenant, agreement, obligation and other
provision contained in this Lease is, and shall be deemed and construed as, a
separate and independent covenant of the party bound by, undertaking or making
the same, and not dependent on any other provision of this Lease.

*Note: Squate Footage and A/C cost is subject to final cost verification and
amount will be adjusted accordingly. After the first lease year if the Tenant
has not fully used the Workletter allowance (above) the Letter of Credit 
may, at Tenant's election, be adjusted to reflect the actual draw of the 
Workletter Allowance.

**The Total Letter of Credit amount will be reduced upon each Lease anniversary 
to the amount indicated in Exhibit G to the Lease reflecting the amortized 
reduction of the landlord investment. (For example, the LC amount in the second 
Lease year shall be $356,248.93.)
