INFORMATION CONTAINED HEREIN IS SUBJECT TO COMPLETION OR AMENDMENT.  A 
REGISTRATION STATEMENT RELATING  TO THESE SECURITIES HAS BEEN FILED WITH THE 
SECURITIES AND EXCHANGE COMMISSION.  THESE SECURITIES MAY NOT BE SOLD NOR MAY 
OFFERS TO BUY BE ACCEPTED PRIOR TO THE TIME THE REGISTRATION STATEMENT BECOMES 
EFFECTIVE. THIS PROSPECTUS SHALL NOT CONSTITUTE AN OFFER TO SELL OR THE 
SOLICITATION OF AN OFFER TO BUY NOR SHALL THERE BE ANY SALE OF THESE

($.01 par value) (the Common Stock) and .25 Charitable Benefit Warrant (the 
"Charitable Benefit Warrants").  Charitable Benefit Warrants may not be 
transferred except to an approved qualified charitable organization.  Each 
Charitable Benefit Warrant entitles an approved qualified charitable 
organization to purchase one share of Common Stock at a price of $20.00 per 
share any time until September __, 2007.  All others may not exercise except 
between September __, 2006, and September __, 2007.  The Charitable Benefit 
Warrants are detachable from the Common Stock immediately on purchase. Prior 
to the Offering, there has been no public market for the Company's Common 
Stock; therefore, the public offering price has been determined solely by the 
Company.  After completion of this Offering, and dependent largely upon the 
number of Units sold in the Offering, the Company's shares may be traded on a 
stock exchange (no application has been made to any stock exchange) or in the 
over-the-counter market, or no active trading market may develop or be 
sustained.  See "Risk Factors" and "Shares Eligible for Future Sale." 
      
     The Offering is being made directly by the Company.  There is no minimum 
number of Units to be sold in the Offering, and all funds received will go 
immediately to the Company.  See "Use of Proceeds."   The Offering will be 
terminated upon the earliest of: the sale of all Units, twelve months after 
the date of this Prospectus (unless extended), or the date on which the 
Company decides to close the Offering.  A minimum purchase of 100 Units 
($1,000) is required.  The Company reserves the right to reject any Unit 
Purchase Agreement in full or in part.  See "Plan of Distribution."  

     The Company is a development stage, biotechnology company which has 
incurred operating losses since its inception.  As of March 31, 1997, the 
Company had an accumulated deficit of $1,341,906.  The Company expects 
substantial additional operating losses in the further development and 
commercialization of its products.

     THE SECURITIES OFFERED ARE SPECULATIVE AND INVOLVE A HIGH DEGREE OF RISK.
ONLY INVESTORS WHO CAN BEAR THE RISK OF LOSS OF THEIR ENTIRE INVESTMENT SHOULD 
INVEST.  FOR A DESCRIPTION OF CERTAIN RISKS OF AN INVESTMENT IN THE COMPANY 
AND IMMEDIATE SUBSTANTIAL DILUTION, SEE "RISK FACTORS" (PAGE 7) AND "DILUTION"

     THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES 
AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES COMMISSION NOR HAS THE

                                   SUMMARY

     The following summary is qualified in its entirety by more detailed 
information and financial statements and notes thereto appearing elsewhere in 
this Prospectus and, accordingly, should be read in conjunction with that 
information.  Prospective investors should carefully consider the information 
set forth under the heading "Risk Factors."  

                                 The Company

      Ixion Biotechnology, Inc. ("Ixion" or the "Company"), is a development 
stage, discovery research biotechnology company, with several product 
candidates in development.  The Company is the holder of world-wide exclusive 
licenses to patents and pending patents in two key areas: diabetes and 
oxalate-related disorders.  Ixion has executive offices and development 
laboratories (including small scale fermentation, cell culture, and 
purification capabilities) at the Biotechnology Development Institute, a small 
business incubator operated by the Biotechnology Program at the University of 
Florida. 

     Ixion is developing diabetes products based on its Islet Progenitor/Stem 
Cell ("IPSC") technology, including a proprietary line of in vitro (in test 
tube) islet stem cells for use in cell transplantation therapy.  This 
development program is aimed at optimizing the growth of functioning islets or 
islet progenitors in vitro from IPSCs which Ixion has established in cell 
cultures.  The Company believes that successful islet transplantation therapy 
will provide better management of diabetes than conventional treatment with 
insulin and other metabolic regulators.  Conventional treatment can result in 
hyper- and hypo-glycemic episodes which are a major cause of diabetic 
complications.  Ixion's technology is intended to ameliorate this condition by 
implanting functional islets into the body in order to  materially improve 
control of blood glucose levels.

     In addition to developing its cell transplantation therapy, Ixion has an 
ongoing discovery program to identify and characterize IPSCs as well as novel 
growth factors associated with them.  The goal of this program is to discover 
factors important in islet cell differentiation and to identify stem cell 
markers to which the Company hopes to produce antibodies useful in stem cell 
isolation.  All of the Company's potential diabetes products are in the 
discovery research stage.

     Diabetes is a chronic, complex metabolic disease.  Type I (often referred 
to as Insulin Dependent Diabetes or IDD) is characterized by an inability to 
produce insulin due to the destruction of the insulin-producing cells of the 
pancreatic islets of Langerhans.   Type I diabetes also leads to many serious 
conditions ranging from death from diabetic coma or insulin shock, to end 
stage renal disease, blindness, amputations, nerve damage, and cardiovascular 
and periodontal disease.  Over 13 million people in the United States have 
diabetes, of whom five to ten percent (or about one million patients) have 
Type I, the most severe form of the disease, and must take insulin.  An 
additional one and one-half million Type II patients also take insulin.  
Annual expenditures on all forms of diabetes are $112 billion, exceeding 
expenditures on cancer.  The Company estimates that approximately 500,000 
patients in the United States could benefit from IPSC-based therapy.  These 
patients currently spend approximately $10 billion annually in treatment of 
their diabetes.

     The Company is also developing products based on its oxalate technology 
for the diagnosis and treatment of  oxalate-related diseases.  Excess oxalate 
from dietary and metabolic sources plays a role in a variety of disorders 
including kidney stones, hyperoxaluria, cardiomyopathy, cardiac conductance 
disorders, cystic fibrosis, Crohn's disease, renal failure and toxic death, 
and vulvodynia.  The anaerobic intestinal bacteria, Oxalobacter formigenes, 
produces enzymes responsible for oxalate degradation in healthy people, and 
inadequate colonies of them result in reduced ability to degrade oxalate. 

     There are approximately one million kidney stone incidents annually in 
the United States.  Annual expenditures on kidney stone incidents exceed $1.8 
billion.  There are approximately 25,000 cystic fibrosis patients in the 
United States; these patients are at materially increased risk of kidney 
stones as a result of excess oxalate.  There are from 5,000 to 16,000 new 
cases of Inflammatory Bowel Disease annually, resulting in 100,000 
hospitalizations, 60% from Crohn's Disease.  Vulvodynia, a chronic 
multifactorial disorder, believed to be in some degree oxalate-related, 
results in painful and debilitating symptoms affecting the tissue surrounding 
the vagina and urethra.  There are no population studies of the incidence or 
prevalence of vulvodynia, but estimates range as high as 150,000 to 200,000 
U.S. women with this condition. Very few effective treatments, if any, exist 
for these disorders.  

     The most developed product candidate in Ixion's development pipeline is a 
combination diagnostic and therapy for the management of oxalate-related 
disorders.  

     The diagnostic component of the Company's oxalate-related disease 
management product is a DNA probe for the rapid and sensitive detection of 
human O. formigenes (the "HOF Probe").  The current tests for O. formigenes 
are laborious, time consuming, and unreliable, and are limited by (1) the 
difficulties of anaerobic culture methods, (2) the inability to standardize 
and accurately quantitate the presence of the bacteria, and (3) the fact that 
the tests cannot be automated.  In addition, the current tests are not 
sensitive and are poorly suited to a clinical setting.  The HOF Probe, on the 
other hand, can accurately and reliably detect very small numbers of O. 
formigenes, is quantitative, and is capable of automation.  

     The therapeutic component of the Company's oxalate-related disease 
management product is an orally administered product consisting of two enzymes 
normally found in O. formigenes and responsible for oxalate degradation ("IxC-
162").  The Company believes that the administration of  these enzymes will 
greatly diminish the recurrence of calcium oxalate kidney stones and will have 
positive therapeutic effects on other oxalate-related disorders.

     The Company intends to file an Investigational New Drug application with 
the Food and Drug Administration for its IxC-162 enzyme therapy for oxalate-
related diseases and an application under Section 510(k) of the Food, Drug, 
and Cosmetic Act for the HOF Probe, both within 12 months from the date of 
this Prospectus.  See "Business - Government Regulation."

     Ixion is in the development stage, has earned only limited revenues, the 
majority of which have been research and development payments, and has 
incurred accumulated deficits of approximately $1,341,906 from its inception 
through March 31, 1997.  See "Risk Factors."

                               

                              The Offering

Securities offered          400,000 Units, each Unit consisting of one share

                            discretion in the use of proceeds, but expects to 
                            use substantially all of such proceeds to fund 
                            research and product development programs and for
                            general corporate purposes.  There is no minimum

                                 RISK FACTORS

     An investment in the securities being offered by this Prospectus is 
highly speculative,  involves a high degree of risk, and should be considered 
only by persons who can afford to lose the entire investment.  In addition to 
the other information contained in this Prospectus, prospective investors 
should carefully consider the following risk factors before purchasing any of 
the Units.

     Early Stage of the Company; Accumulated Deficit.  The Company is in the 
development stage, and has realized only limited revenues, most of which have 
derived from payments from Genetics Institute, Inc., a subsidiary of American 
Home Products Corp., in connection with contract research and development 
under a sponsored research agreement.  No revenues have been generated from 
product sales.  The Company will be required to do significant research, 
development, testing, and regulatory compliance activities which, together 
with projected general and administrative expenses, are expected to result in 
material and increasing operating losses for the foreseeable future. There can 
be no assurance that the Company will successfully complete the transition 
from a development stage company to successful operations or profitability.   
At March 31, 1997, the Company had an accumulated deficit during the 
development stage of $1,341,906.

     Potential investors should be aware of the problems, delays, expenses, 
and difficulties encountered by any company in the development stage, many of 
which may be beyond the Company's control.  These include, but are not limited 
to, unanticipated problems and additional costs relating to development, 
testing, regulatory compliance, production, marketing, and competition.

     Absence of Products; No Commercialization of Products Expected in Near 
Future.  The Company's product candidates are in an early stage of 
development.  The Company has not completed the development of any products 
and, accordingly, has not received any regulatory approvals or commenced 
marketing activities.  No revenues have been generated from the sale of its 
products.  The Company's product candidates will require significant 
additional development, preclinical and clinical trials, regulatory approval, 
and additional investment prior to commercialization. The Company may be 
unable to market any products for several years.  Furthermore, it will be a 
number of years, if ever, before the Company will recognize significant 
revenues from product sales or royalties.  In addition, the Company's product 
candidates are subject to the risks of failure inherent in the development of 
products based on innovative technologies.  Accordingly, there can be no 
assurance that the Company's research and development efforts will be 
successful, that any of the Company's product candidates will prove to be 
safe, effective, and non-toxic in clinical trials, that any commercially 
successful products will be developed, that the proprietary or patent rights 
of others will not preclude the Company from marketing its product candidates, 
or that others will not develop competitive or superior products.  As a result 
of the early stage of development of product candidates and the extensive 
testing and regulatory review process that such product candidates must 
undergo, the Company cannot predict with certainty when it will be able to 
market any of its products, if at all.  The Company's product development 
efforts are based on unproven scientific approaches.  There is, therefore, 
substantial risk that these approaches may not prove to be successful.  See 
"Business - Product Development."

     Uncertainty Associated with Pre-clinical and Clinical Testing.  Before 
obtaining regulatory approvals for the commercial sale of any of the Company's 
products, the products will be subject to extensive preclinical and clinical 
trials to demonstrate their safety and efficacy in humans.  The Company 
intends to employ third parties to conduct clinical trials of its products 
because it has no experience in conducting clinical trials.  Preclinical 
studies have been commenced with regard to two of the Company's oxalate 
products; however, no clinical trials have been commenced with respect to any 
of the Company's potential products.  Furthermore, there can be no assurance 
that preclinical or clinical trials of any of the Company's products will 
demonstrate the safety and efficacy of such product at all or to the extent 
necessary to obtain regulatory approvals.  Companies in the biotechnology 
industry have suffered significant setbacks in advanced clinical trials, even 
after demonstrating promising results in earlier trials.  The failure to 
adequately demonstrate the safety and efficacy of a product candidate under 
development could delay or prevent regulatory approval of the product 
candidate and would have a material adverse effect on the Company's business, 
operating results, and financial condition. See "Business - Government 
Regulation."  
     
     Need for Additional Financing.  Based on its current operating plan, the 
Company expects that the net proceeds of this Offering, assuming the sale of 
all the Units offered hereby, together with contract research revenue and 
possible grant income from grant applications made or to be made, will be 
adequate to satisfy its planned operating requirements for approximately 15 
months, but will not be sufficient to fund the Company's operations to the 
point of introduction of a commercially successful product.  

     The Company will require significant levels of additional capital and its 
future capital requirements will depend on many factors, including the degree 
of success of the present Offering, the costs involved in future capital 
raising activities, continued scientific progress in its research and 
development programs, the magnitude of such programs, the potential addition 
of new programs, the progress of preclinical and clinical testing, the time 
and costs involved in obtaining regulatory approvals, the costs involved in  
preparing, filing, prosecuting and enforcing patent claims, competing 
technological and market developments, the establishment of collaborative 
agreements, costs of commercialization activities, and the demand for the 
Company's products, if and when approved.  Ixion intends to commence 
additional financing activities shortly after the closing of this Offering, 
and it intends to seek further funding through additional arrangements with 
corporate partners,  through public or private sales of debt or equity, or 
through other sources.  Future financings may result in the issuance of 
securities which are senior to the Shares or result in substantial additional 
dilution of shareholders.  There can be no assurance that additional funding 
will be available on acceptable terms, if at all.  If adequate funds are not 
available, the Company may be required to curtail significantly or defer one 
or more of its research and development programs or to obtain funds through 
arrangements that may require the Company to relinquish certain technological 
or product rights.  See "Management's Discussion and Analysis of Financial 
Condition and Results of Operations - Liquidity and Capital Resources" and 
"Use of Proceeds."

     No Minimum Amount for This Offering.   Because there is no minimum amount 
of Units required to be sold in the Offering, all the cash received will go 
directly to the Company to be used as described in "Use of Proceeds."  If only 
a few Units are sold, the result could be that all the proceeds will be used 
to pay the expenses of the Offering.

     Management's Broad Discretion in Application of Proceeds.  The Company 
intends to use the proceeds of the Offering to pay the costs of the Offering 
and the balance will be added to the Company's working capital where it will 
be available for general corporate purposes, including the funding of the 
Company's research and development activities.  As of the date of this 
Prospectus, the Company cannot specify with certainty the particular uses for 
the net proceeds to be added to its working capital.  Accordingly, management 
of the Company will have broad discretion as to the application of the net 
proceeds of the Offering.  See "Use of Proceeds" and "Management's Discussion 
and Analysis of Financial Condition and Results of Operations - Product 
Research and Development Plan."

     Earnings Inadequate to Pay Fixed Charges.  Earnings  are, and will for 
the foreseeable future remain, inadequate to cover fixed charges, including 
interest on the Company's 10% Unsecured Convertible Notes.  Payment of 
principal on the 10% Unsecured Convertible Notes and the Unsecured Variable 
Convertible Notes will be dependent on the Company's ability to raise 
additional funds through the sale of its securities, corporate alliances, or 
otherwise. 

     Dependence on Key Personnel and Relationships.  Ixion is dependent on its 
executive officers, consultants, and its  scientific advisors, especially Dr. 
Ammon Peck, the Company's Chief Scientist and Chairman of the Scientific 
Advisory Board.  The Company has only one full-time executive, Weaver H. 
Gaines, Chairman and Chief Executive Officer.  Three of the Company's officers 
- - David C. Peck, President and Chief Financial Officer, John L. Tedesco, Vice 
President - Operations and Regulatory Affairs, and Kimberly A. Ramsey, 
Controller, are consultants who devote substantial time to other employers.  
Ixion has an employment contract with Mr. Gaines, an exclusive consulting 
agreement with Dr. Peck, and consulting agreements with Messrs. Tedesco and 
David Peck.  The agreements of Dr. Peck, Mr. Gaines, Mr. Peck, and Mr. Tedesco 
all contain non-compete provisions.  See  "Management - Consulting Agreement 
with Dr. Peck," "Management - Consulting Agreement with Brandywine 
Consultants, Inc.," and  "Management - Employment Agreements." The loss of any 
individuals on which the Company is dependent could have a material adverse 
effect on the Company.  Ixion has a key person life insurance policy in the 
face amount of $500,000 on Dr. Peck.

     Competition among pharmaceutical and biotechnology companies for 
qualified employees is intense, and the loss of qualified employees, or an 
inability to attract, retain, and motivate additional highly skilled employees 
required for the expansion of the Company's activities, could adversely affect 
its business and prospects.  Gainesville, Florida is a developing  area for 
biotechnology, and to date there are few companies located there.  This fact 
is an inhibition on both recruiting and retaining personnel.  There can be no 
assurance that the Company will be able to retain its existing personnel or to 
find and attract additional qualified and experienced employees.

     Individuals whom the Company has targeted to be its scientific 
collaborators and its current and proposed scientific advisors are employed by 
employers other than the Company, and some have consulting or other advisory 
arrangements with other entities that may conflict or compete with their 
obligations to the Company.  See "Business  - Scientific Advisory Board."

     Reliance on Relationships with the University of Florida.  The Company 
has sought to maintain a close and favorable relationship with the University 
of Florida since 1993 when the Company was founded.  The Company expects to 
benefit, and has already benefited, from its relationship with the University 
of Florida, in particular from the basic research performed.  This 
relationship includes certain contractual arrangements, particularly the 
License Agreement for Islet Progenitor/Stem Cells and the License Agreement 
for oxalate technology.  Negotiations have also commenced to license other 
technologies.  In addition, the Company is an affiliate of the Biotechnology 
Program of the University, which provides certain business support services to 
the Company, it has its labs and offices at the Biotechnology Development 
Institute, a University facility, and its Chief Scientist and two members of 
its Scientific Advisory Board are faculty members at the University.  See 
"Business - Facilities" and "Business - Scientific Advisory Board."  There can 
be no assurance that disputes or disagreements will not cause the favorable 
relationship to deteriorate.  A deterioration in the relationship between the 
Company and the University of Florida could have a material adverse effect  on 
the Company.  In particular, the Company could be forced to expand 
substantially its research facilities and staff to replace or supplement the 
research currently performed by researchers at the University of Florida.  
Additionally, if the University of Florida were to suffer financial or 
operating setbacks in the future, such as in financing, research staff, 
research efforts, facilities or management, such setbacks could have a 
material adverse impact on the Company's future technology.  Moreover, the 
Company has no input into or control over the direction or content of research 
undertaken by the University  of Florida.  Accordingly, no assurance can be 
given that discoveries made at the University of Florida, if any, will be 
capable of being developed or marketed, will fall within the Company's areas 
of expertise or interest, or will be available to the Company on acceptable 
terms.  See "Business - Business Strategy," "Business - Relationship with the 
University of Florida," and "Business - Licensed Technology."

     State of Florida and University of Florida Conflicts of Interest Laws and 
Rules.  The Company's Chief Scientist and two members of its Scientific 
Advisory Board are employees of the Florida State University System, and, as a 
result, they (and consequently the Company) are subject to Florida statutes 
and University policy regarding conflicts of interest.  In order for the 
Company to conduct business with the University (including its license 
agreements, future cooperative research and development agreements, and other 
activities), it is necessary to obtain and maintain an annual exemption from 
the application of the Florida conflict of interest statutes for its Chief 
Scientist, and to obtain annual approval for outside activities for the 
Florida members of its Scientific Advisory Board.  If the University were to 
decline to approve the outside activities of the Company's Chief Scientist, or 
the Florida members of its Scientific Advisory Board, or were to change the 
terms of its conflicts of interest policy, it could have a material adverse 
effect on the Company.  See "Business - Government Regulation."

     Dependence on Licensed Technology.  The Company's development and 
commercialization rights for its proposed products are derived from its 
license agreements with the University of Florida and others.  To date, the 
Company owns no patents outright.  The Company's rights under license 
agreements are subject to early termination under certain circumstances, 
including failure to pay royalties or other material breach by the Company or  
bankruptcy of the Company, among others.  In the event that the license 
agreements terminate for any reason, the Company's rights to manufacture and 
market products derived from those licenses would terminate.  See "Business - 
Licensed Technology."

     Ethical, Legal, and Social Implications of Islet Progenitor/Stem Cell 
Therapies.  The Company's Islet Progenitor/Stem Cell ("IPSC") program may 
involve the use of IPSCs that would be derived from cloned human materials, 
and therefore may raise certain ethical, legal, and social issues regarding 
the appropriate utilization of this technique.  The cloning of human tissue in 
scientific research is an issue of national interest.  Many research 
institutions have adopted policies regarding the ethical uses of cloning, and 
state and federal legislatures are considering legislation regarding cloned 
human materials.  These policies may have the effect of limiting the scope of 
research conducted in this area, resulting in reduced scientific progress.  
The inability of the Company to conduct research on IPSCs due to such factors 
as government regulation or otherwise could have a material adverse effect on 
the program. In the event the Company's research related to IPSC-based 
therapies becomes the subject of adverse commentary or publicity, the 
Company's name and goodwill could be adversely affected.  

     Intense Competition.   The biotechnology and pharmaceutical industries 
are intensely competitive and subject to rapid and significant technological 
change.  Competitors of the Company are numerous and include, among others, 
major, multinational pharmaceutical and chemical companies, specialized 
biotechnology firms, and universities and other research institutions.  Many 
of these competitors have greater financial and other resources, including 
larger research and development staffs, than the Company.  Acquisitions of 
competing companies and potential competitors by large pharmaceutical 
companies or others could enhance financial, marketing and other resources 
available to such competitors. As a result of academic and government 
institutions becoming increasingly aware of the commercial value of their 
research findings, such institutions may be more likely to enter into 
exclusive licensing agreements with commercial enterprises, including 
competitors of the Company, to market commercial products.  There can be no 
assurance that the Company's competitors will not succeed in developing 
technologies and products that are more effective or less costly than any 
which are being developed by the Company or which would render the Company's 
technology and future drugs obsolete and noncompetitive.  

     In addition, some of the Company's competitors have greater experience 
than the Company in conducting preclinical and clinical trials and obtaining 
U.S. Food and Drug Administration ("FDA") and other regulatory approvals.  
Accordingly, the Company's competitors may succeed in obtaining FDA or other 
regulatory approvals for competitive product candidates more rapidly than the 
Company.  Companies that complete clinical trials, obtain required regulatory 
agency approvals, and commence commercial sale of their drugs before their 
competitors may achieve a significant competitive advantage, including certain 
patent and marketing exclusivity rights.  There can be no assurance that 
products resulting from the Company's research and development efforts will be 
able to compete successfully with competitors' existing products or products 
under development or that they will obtain regulatory  approval in the United 
States or elsewhere.   See "Business - Competition."

     Uncertainty Regarding Patents and Proprietary Rights.      The Company's 
success will depend in part on its ability to obtain U.S. and foreign patent 
protection for its product candidates and processes, to protect its trade 
secrets, and to avoid infringing the proprietary rights of others.  Because of 
the length of time and expense associated with bringing new drug or medical 
device candidates through the development and regulatory approval process to 
the marketplace, the Company stresses the considerable importance of obtaining 
patent and trade secret protection for its new technologies, products, and 
processes.  One U. S. patent has been issued concerning certain of the 
Company's oxalate-based claims and certain claims pertaining to the IPSC 
technology have been allowed by the U. S. Patent and Trademark Office ("PTO"); 
however, there can be no assurance that any additional patents will be issued 
covering any of the patent applications licensed to the Company.  Further, 
there can be no assurance that any rights the Company may have under issued 
patents will provide the Company with significant protection against 
competitive products or otherwise be commercially viable.  Legal standards 
relating to the validity of patents covering pharmaceutical and 
biotechnological inventions and the scope of claims made under such patents 
are still developing.  There is no consistent policy regarding the breadth of 
claims allowed in biotechnology patents.  The patent position of a 
biotechnology firm is highly uncertain and involves complex legal and factual 
questions.  There can be no assurance that any existing or future patents 
issued to, or licensed by, the Company will not subsequently be challenged, 
infringed upon, invalidated, or circumvented by others.  In addition, patents 
may have been granted, or may be granted, covering products or processes that 
are necessary or useful to the development of the Company's products.  If the 
Company's product candidates or processes are found to infringe upon the 
patents, or otherwise impermissibly utilize the intellectual property of 
others, the Company's development, manufacture, and sale of such products 
could be severely restricted or prohibited.  In such event, the Company may be 
required to obtain licenses from third parties to utilize the patents or 
proprietary rights of others.  There can be no assurance that the Company will 
be able to obtain such licenses on acceptable terms, or at all. 

     A number of pharmaceutical companies, biotechnology companies, 
universities and research institutions, and individuals have filed patent 
applications or received patents to technologies that are similar to the 
technologies licensed by the Company.  In addition, there can be no assurance 
that the Company is aware of all patents or patent applications that may 
materially affect the Company's ability to make, use, or sell any products.  
Any conflicts resulting from third party patent applications and patents could 
significantly reduce the coverage of the patents or patent applications 
licensed to the Company and limit the ability of the Company to obtain 
meaningful patent protection.  If patents are issued to other companies that 
contain competitive or conflicting claims, the Company may be required to 
obtain licenses to these patents or to develop or obtain alternative 
technology.  There can be no assurance that the Company will be able to obtain 
any such license on acceptable terms or at all.  If such licenses are not 
obtained, the Company could be delayed in or prevented from the development or 
commercialization of its product candidates, which would have a material 
adverse effect on the Company.  See "Business - Licensed Technology."

     In addition to patent protection, the Company relies on trade secrets, 
proprietary know-how and technological advances which it seeks to protect, in 
part, by confidentiality agreements with its collaborators, employees, and 
consultants. There can be no assurance that these confidentiality agreements 
will not be breached, that the Company would have adequate remedies for any 
such breach, or that the Company's trade secrets, proprietary know-how, and 
technological advances will not otherwise become known or be independently 
discovered by others. 

     Dependence on Reimbursement.  The Company's ability to commercialize its 
planned products successfully will depend in part on the extent to which 
reimbursement for the cost of such products and related treatments will be 
available from government health administration authorities, such as the 
Health Care Financing Administration, private health insurers, managed care 
plans, and other organizations.  Government and other third-party payors are 
increasingly attempting to contain health care costs, in part by challenging 
the price or benefit of medical products and services. Products with long-term 
benefits but initial short-term costs may not be acceptable to managed care 
plans or others with short-term payback requirements.  Thus, significant 
uncertainty exists as to the reimbursement status of newly approved health 
care products, and there can be no assurance that adequate third-party 
coverage will be available to enable the Company to maintain price levels 
sufficient to realize an appropriate return on its investment in product 
development.  If adequate coverage and reimbursement levels are not provided 
by government and third-party payors for use of the Company's planned 
products, the ability to market those products would be adversely affected.

     No Assurance of Market Acceptance for Proposed Products.  There can be no 
assurance that any products successfully developed by the Company, 
independently or with its collaborative partners, if approved for marketing, 
will achieve market acceptance.  The degree of market acceptance of any 
products developed by the Company will depend on a number of factors, 
including the establishment and demonstration of the clinical efficacy and 
safety of the Company's products, their potential advantage over existing 
therapies or diagnostics, and reimbursement policies of government and 
third-party payors.  There is no assurance that physicians, patients, 
independent laboratories, or the medical community in general will accept and 
utilize any products that may be developed by the Company.

     Government Regulation; No Assurance of Regulatory Approval.  The 
Company's activities are subject to extensive regulation by the FDA and health 
authorities in foreign countries.  Regulatory approval for the Company's 
planned products (other than those for research rather than diagnostic or 
therapeutic use), will be required before such products may be marketed.  The 
process of obtaining regulatory authorization involves, among other things, 
lengthy and detailed laboratory and clinical testing, manufacturing 
validation, and other complex and extensive procedures.  The approval process 
is costly, time-consuming, and often subject to unanticipated delays.  In the 
United States, the FDA has discretion in the approval process, and it is not 
possible to predict at what point, or whether, the FDA will be satisfied with 
the quality or quantity of information submitted by the Company to support its 
applications for marketing approval.  There can be no assurance that the FDA 
will not require additional information or additional clinical trials which 
could substantially delay approval of applications.  Moreover, there can be no 
assurance that FDA approval will cover the clinical indications for which the 
Company intends to seek approval, or will not contain significant limitations 
in the form of, for example, warnings, precautions, or contra-indications with 
respect to conditions of use.  There can be no assurance that approvals for 
any of the Company's products, processes, or facilities will be granted on a 
timely basis, if at all.  Any failure to obtain, or any delay in obtaining, 
such approvals would materially and adversely affect the Company.  Further, 
even if such regulatory authorizations are obtained, a marketed product and 
its manufacturer are subject to continuing regulatory requirements and review, 
and later discovery of previously unknown problems with a product or 
manufacturer, or failure to comply with manufacturing or labeling 
requirements, may result in restrictions on such product or enforcement action 
against the manufacturer, including withdrawal of the product from the market.
See "Business - Government Regulation."

     Risk of Product Liability; Insurance.  The use of any products produced 
by the Company could expose the Company to product liability claims.  The 
Company currently carries no product liability insurance, but intends to 
acquire such insurance prior to selling any of its licensed products for 
commercial use.  There can be no assurance that the Company will be able to 
obtain or maintain such insurance, or if obtained, that sufficient coverage 
can be acquired at a reasonable cost.  An inability to obtain or maintain 
insurance at acceptable cost or otherwise protect against potential product 
liability claims could prevent or inhibit the commercialization of the 
Company's planned products, including its research use only products.  A 
product liability claim or recall could have a material adverse effect on the 
business or the financial condition of the Company.

     Absence of Public Trading Market for Securities; Valuation.  There is no 
public market for the Common Stock, and it is unlikely that any such market 
will develop after the Offering.  There is no public market for the Charitable 
Benefit Warrants.  By the terms of such Warrants, they will not be tradable 
following the Offering.  The Company does not currently meet the requirements 
for listing on an organized stock exchange or quotation of over-the-counter 
market maker trades on the Nasdaq market. After completion of the Offering, 
the Company may apply for a listing on a United States regional exchange, if 
the Company meets certain numerical listing requirements.  However, there can 
be no assurance that the Company will be listed or that a market will develop 
or be sustained.  If it does not, the Company has been advised that a 
registered securities broker-dealer may provide an order matching service for 
persons wishing to buy or sell shares, upon completion of the Offering.  
However, there is currently no agreement between the Company and such a 
registered securities broker-dealer.  The Company may, in the future, seek to 
provide a passive, bulletin board system on the Internet providing information 
to buyers and sellers of the Company's Common Stock to facilitate trading.  In 
the absence of a public trading market, purchasers may be unable to resell the 
Common Stock for an extended period of time, if at all.  See "Plan of 
Distribution."  

     Development stage biotechnology valuations are rarely based upon 
traditional financial standards, like earnings multiple, current yield, or 
book value.  In fact, the perception of the future value of the proprietary 
science, and any possible applications deriving from it, together with 
relative illiquidity and momentum often form the basis of stock performance  
in this industry.  There is great risk that external perceptions will change 
over time, subsequently affecting the Company's ability to fund its 
operations.   Thus, future trading prices, if any, of the Company's securities 
will depend on many factors, including, among others, those mentioned above, 
together with prevailing interest rates, the Company's operating results, 
preclinical and clinical trial results, scientific defections, personnel 
turnover at corporate partners, general conditions in the biotechnology 
industry, announcements of discoveries of new products by the Company, its 
competitors, and others, and the market for similar securities, which market 
is subject to various pressures, including, but not limited to, fluctuating 
interest rates.  In addition, the stock market is subject to price and volume 
fluctuations unrelated to the operating performance of the Company.

     Determination of Offering Price.  The Company has unilaterally and 
arbitrarily determined the offering price of the Units.  Among the factors 
considered in determining such price were offering prices of recent 
biotechnology initial public offerings, the Company's capital requirements, 
the percentage of ownership to be held by investors following the Offering, 
the prospects for the Company's business and the biotechnology industry, the 
assessment of the present early stage of the Company's development, the 
prospects for initiation or growth of the Company's revenues, and the current 
state of the economy in the United States.  The offering price does not 
necessarily bear any relationship to the Company's assets, book value, 
earnings history, or other investment criteria and  should not be considered 
an indication of the actual value of the Company's securities.  See "Plan of 
Distribution."
     
     Control by Management and Existing Shareholders.  At July 1, 1997, the 
current officers, directors, and members of their families sharing their 
household own or have rights to acquire within the next 60 days, directly or 
beneficially, 1,658,021 shares of Common Stock representing approximately 67% 
of the outstanding shares of the Company's Common Stock.  Following the 
Offering,  such persons will own approximately 57% of the Company's Common 
Stock, and are and will be, able to control all matters requiring approval by 
the stockholders of the Company, including the election of Directors.  Such 
concentration of ownership may also have the effect of delaying or preventing 
a change in control of the Company that may be favored by other stockholders.  
See "Management" and "Principal Shareholders."

     Possible Adverse Impact of Shares Available for Future Sale.  Sales of 
substantial amounts of Common Stock (including shares issued upon the exercise 
of outstanding options and warrants or upon the conversion of the Unsecured 
Convertible Notes) in the public market, if any, after this Offering or the 
prospect of such sales could adversely affect any  market price of the Common 
Stock and may have a material adverse effect on the Company's ability to raise 
any necessary capital to fund its future operations.  Upon completion of this 
Offering, assuming all Units are sold, the Company will have 2,864,544 shares 
of Common Stock outstanding.  The 400,000 shares included in the Units offered 
hereby will be freely tradable without restriction or further registration 
under the Securities Act of 1933, as amended (the "Securities Act"), except 
for any shares held by "affiliates" of the Company within the meaning of the 
Securities Act which will be subject to the resale limitations of Rule 144 
promulgated under the Securities Act ("Rule 144").  The remaining 2,464,544 
shares are "restricted" securities that may be sold only if registered under 
the Securities Act, or sold in accordance with an applicable exemption from 
registration, such as Rule 144.  The officers and directors, who together hold 
1,628,544 shares of Common Stock, and rights  to purchase an additional 39,452 
shares of Common Stock, have agreed not to sell directly or indirectly, any 
Common Stock for a period of 180 days from the date of this Prospectus (the 
"Lock-up Agreements").  Commencing on the expiration of the Lock-up 
Agreements, 1,628,544 shares of Common Stock will be eligible for sale in the 
public market, if any, subject to compliance with Rule 144.  In addition, 
holders of 1,051,544 shares of Common Stock, and holders of warrants and 
Unsecured Convertible Notes convertible into a maximum of an additional 
340,917 shares of Common Stock, will be entitled to certain registration 
rights with respect to such shares.  If such holders, by exercising their 
registration rights, cause a large number of shares to be registered and sold 
in the public market, if any, such sales could have a material adverse effect 
on the market price of the Common Stock.  In addition, any demand of such 
holders to include such shares in Company-initiated registration statements 
could have an adverse effect on the Company's ability to raise needed capital.
See "Shares Eligible for Future Sale - Registration Rights."
 
     Immediate and Substantial Dilution.  This Offering involves an immediate 
and substantial dilution between the initial public offering price of $10.00 
per share and the pro forma net tangible book value per share of Common Stock 
after the Offering.  Such dilution will amount to $8.98 (90%) if all Units are 
sold; $9.30 (93%) if 75% of the Units are sold; $9.65 (97%) if 50% of the 
Units are sold; and $10.03 (100%) if 25% of the Units are sold.  Dilution will 
be increased to the extent that the holders of outstanding options, warrants, 
and Unsecured Convertible Notes who have rights to acquire Common Stock at 
prices below the public offering price exercise such rights.  See "Dilution." 

     Dividends.  Ixion has never paid any cash dividends and does not intend 
to pay any cash dividends on its Common Stock in the foreseeable future.

     Limited Experience in Sales and Marketing.  The Company has no 
significant experience in pharmaceutical sales, marketing, or distribution.  
To market any of its products directly, the Company must develop a substantial 
marketing and sales force with technical expertise and supporting distribution 
capability.  Alternatively, the Company intends, for certain product 
candidates, to obtain the assistance of companies with established 
distributions systems and direct sales forces.  There can be no assurance that 
the Company will be able to establish sales and distribution capabilities, 
will be able to enter into licensing or other agreements with established 
companies, or will be successful in gaining market acceptance for its 
products.  See "Business - Business Strategy" and "Business - Manufacturing 
and Marketing."

     Absence of Manufacturing Facilities or Personnel; Dependence on Others.  
The Company owns no manufacturing facilities or equipment, and employs no 
direct manufacturing personnel.  The Company anticipates using third parties 
to manufacture its products on a contract basis.  There can be no assurance 
that the Company will be able to obtain such manufacturing services on 
reasonable terms.  Having obtained such services, the Company would be 
dependent on its ability to manage all parties who may hereafter conduct 
manufacturing for it.  See "Business - Business Strategy" and "Business - 
Facilities."

     Limitation on Liability of Directors and Officers. As permitted by 
Delaware law, the Certificate of Incorporation provides that no director of 
the Company will be liable for money damages for breach of fiduciary duty as a 
director, except (i) for any breach of the director's duty of loyalty to the 
Company or its stockholders, (ii) for acts or omissions not in good faith or 
involving intentional misconduct or a knowing violation of law, (iii) for 
approval of certain unlawful dividends or stock purchases or redemptions, and 
(iv) for any transaction from which the director derived an improper personal 
benefit.  See "Description of Securities."

              SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
 
     Statements herein regarding the dates on which the Company anticipates 
commencing clinical trials or filing of an Investigational New Drug Exemption 
Application ("IND") or application under Section 510(k) of the Food, Drug, and 
Cosmetic Act with respect to its product candidates, constitute 
forward-looking statements under the federal securities laws.  Such statements 
are subject to certain risks and uncertainties that could cause the actual 
timing of such clinical trials or filings to differ materially from those 
projected.  With respect to such dates, the Company's management team has made 
certain assumptions regarding, among other things, the successful and timely 
completion of preclinical tests, the approval of INDs for each of the 
Company's drug candidates by the FDA, the availability of Section 510(k) for 
its device candidates, the availability of adequate clinical supplies, the 
absence of delays in patient enrollment, and the availability of the capital 
resources necessary to complete the preclinical tests and conduct the clinical 
trials.  The Company's ability to commence clinical trials or file an IND or 
510(k) on the dates anticipated is subject to certain risks, including the 
risks discussed under "Risk Factors."  Undue reliance should not be placed on 
the dates on which the Company anticipates filing an IND or 510(k) or 
commencing clinical trials with respect to any of its product candidates.  
Statements herein regarding the Company's research and development plans also 
constitute forward looking statements under the federal securities laws.  
Actual research and development activities may vary significantly from the 
current plans depending on numerous factors including changes in the costs of 
such activities from current estimates, the results of the programs, the 
results of clinical studies referred to above, the timing of regulatory 
submissions, technological advances, determinations as to commercial 
potential, and the status of competitive products.

     All of the above estimates are based on the current expectations of the 
Company's management team, which may change in the future due to a large 
number of potential events, including unanticipated future developments.

                               USE OF PROCEEDS

     The net proceeds to the Company from the sale of the Units, after 
deduction of estimated offering expenses, is set forth in the table below.  
The following table sets forth the Company's anticipated use of proceeds at 
each level of Units sold.  There is no minimum number of Units which must be 
sold in the Offering, and all funds will be paid directly to the Company.

The Company intends to use a majority of the net proceeds (regardless of 
the number of Units sold) to fund the Company's general corporate operations 
and research and development activities, including product characterization, 
method development, testing (including toxicology), cell line 
characterization, process development, clinical lot manufacturing, stability 
research protocols, and preclinical studies for the Company's proposed 
products.  The amounts and timing of expenditures for each purpose is subject 
to the broad discretion of the management and will depend on the progress of 
the Company's research and development programs, technological advances, 
determinations as to commercial potential, the terms of any collaborative 
arrangements entered into by the Company for development and licensing, 
regulatory approvals, and other factors, many of which are beyond the 
Company's control.

     The foregoing represents the Company's best estimate of its allocation of 
the proceeds of this Offering, based upon the current state of the Company's 
business operations and its current plans.  In the opinion of management, in 
the event 100% of the Units offered are sold, the net proceeds of this 
Offering, together with anticipated revenues from operations, will satisfy the 
Company's planned operating requirements for at least 15 months.

     Until required for operations, the Company's policy is to invest its cash 
reserves in bank deposits, certificates of deposit, commercial paper, 
corporate notes, U.S. government instruments, and other investment-grade 
quality instruments.

______________________
(1) "Net tangible book deficit per share" is determined by dividing the 
number of shares of Common Stock outstanding into the tangible net deficit of 
the Company (tangible assets less total liabilities).
(2) "Dilution"  means the difference between the public offering price per 
share and the net tangible book value (deficit) per share of Common Stock 
after giving effect to the Offering.
(3) Does not include the effects of any options or warrants or conversion 
of the Company's Unsecured Convertible Notes.

The Company was initially capitalized by a sale of Common Stock to its 
founders.  Subsequently, the Company has completed two private placements of 
Common Stock and a private placement of Unsecured Convertible Notes.  The 
following table sets forth the difference between the Company's officers, 
directors, promoters, and affiliates thereof, and purchasers of the Units in 
the Offering with respect to the number of shares purchased from the Company 
(or which such persons have the right to purchase), the total cash 
consideration paid (or to be paid), and the average price per share.  The 
table assumes that all of the Units offered hereby are sold.

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

     The following discussion and analysis should be read in conjunction with 
the Financial Statements and the related Notes thereto included elsewhere in 
this Prospectus.   This Prospectus contains forward-looking statements which 
involve risks and uncertainties.  The Company's actual results may differ 
significantly from the results discussed in the forward-looking statements.  
Factors that might cause such a difference include, but are not limited to, 
those discussed in "Risk Factors" and in "Special Note Regarding Forward-
Looking Statements."

Overview

     The Company is a development stage, biotechnology company.   The Company 
is considered to be in the development stage because it is devoting 
substantially all of its efforts to establishing its business and its planned 
principal operations have not commenced.  

     Since its inception in March of 1993, the Company's efforts have been 
principally devoted to research and development, securing patent protection, 
and raising capital. The Company has not received any revenues from the sale 
of products, and does not expect any of its product candidates to be 
commercially available for at least the next two to five years.  From 
inception through March 31, 1997, the Company has sustained cumulative losses 
of $1,341,906.  These losses have resulted primarily from expenditures 
incurred in connection with general and administrative activities, research 
and development, patent preparation and prosecution, and interest.  

     The Company expects to continue to incur substantial research and 
development costs in the future resulting from ongoing research and 
development programs, manufacturing of products for use in clinical trials and 
preclinical and clinical testing of the Company's products.  The Company also 
expects that general and administrative costs, including patent and regulatory 
costs, necessary to support clinical trials, research and development, 
manufacturing, and the creation of a marketing and sales organization, if 
warranted, will increase in the future.   Accordingly, the Company expects to 
incur increasing operating losses for the foreseeable future.   There can be 
no assurance that the Company will ever achieve profitable operations.

     To date, the Company has not marketed, or generated revenues from the 
commercialization of, any products.  The Company's current drug candidates are 
not expected to be commercially available for several years.

     The Company has only a limited operating history upon which an evaluation 
of the Company and its prospects can be based. The risks, expenses and 
difficulties encountered by companies at an early stage of development must be 
considered when evaluating the Company's prospects. To address these risks, 
the Company must, among other things, successfully develop and commercialize 
its product candidates, secure all necessary proprietary rights, respond to 
competitive developments, and continue to attract, retain and motivate 
qualified persons. There can be no assurance that the Company will be 
successful in addressing these risks. See "Risk Factors - Early Stage of the 
Company; Accumulated Deficit."       

     The operating expenses of the Company will depend on several factors, 
including the level of research and development expenses.  Research and 
development expenses will depend on the progress and results of the Company's 
product development efforts, which the Company cannot predict.  Management may 
in some cases be able to control the timing of development expenses in part by 
accelerating or decelerating preclinical testing and clinical trial 
activities. As a result of these factors, the Company believes that period-to-
period comparisons in the future are not necessarily meaningful and should not 
be relied upon as an indication of future performance.  Due to all of the 
foregoing factors, it is possible that the Company's operating results will be 
below the expectations of market analysts, if any, and investors.  In such 
event, the prevailing market price, if any, of the Common Stock would likely 
be materially adversely affected. See "Risk Factors - Absence of Public 
Trading Market for Securities; Valuation."



Results of Operations

Three Months Ended March 31, 1996 and 1997
 
     The Company revenues under research agreements increased from none in the 
first three months of 1996 to $87,312 in the first three months of 1997, due 
entirely to recognition and receipt of income from a research support 
agreement with Genetics Institute, Inc.  Revenues under the Genetics Institute 
agreement are expected to cease at the end of the agreement in 1997.  Income 
of approximately $73,000 under the Company's SBIR grant is expected during 
1997.

     Interest income increased 640% from $599 in the first quarter of 1996 to 
$4,435 in the same period in 1997.  This increase was attributable to the 
investment of the proceeds from the sale of Unsecured Convertible Notes in the 
last quarter of 1996.  Interest income will decline as these funds are used 
for operating expenses.

     Operating, general and administrative expenses increased 75% from $61,362 
in the first three months of 1996 to $107,396 in the first three months of 
1997.  These increased expenses reflect increased personnel, including a 
secretary hired in June 1996 and the employment of a Vice President - 
Operations and Regulatory Affairs in December 1996.  The Company expects its 
general and administrative expense to continue to increase during the 
remainder of 1997 and 1998 as a result of the forgoing increases in personnel 
who will be employed for the full year of 1997 as well as the hiring of 
additional personnel.

     Research and development expenditures consist primarily of payroll-
related expenses of research and development personnel, laboratory supplies, 
animal supplies, laboratory rent, depreciation on laboratory equipment, 
development activities, payments for sponsored research, and payments to 
scientific and regulatory consultants.  Research and development expenses 
increased 242% from $39,612 in the first quarter of 1996 to $135,653 in the 
first quarter of 1997, primarily as a result of additional research personnel 
and increased research activities. The Company anticipates that its research 
and development expenses will increase during the next 12 months as the 
Company continues to fund research and development programs and preclinical 
and clinical testing for its product candidates and technologies under 
development.

     Interest expense increased 128% from $5,779 in the first three months of 
1996 to $13,154 in the first three months of 1997 due primarily to interest 
paid on the Company's Unsecured Convertible Debt, issued in the last quarter 
of 1996, and the compounding of interest on deferred fees and salaries, 
including deferred interest, payable to related parties.  See "Management - 
Deferred Compensation Plan."  Interest will continue to increase during 1997 
as a result of the Unsecured Convertible Notes' being outstanding for the 
entire year, and as a result of the compounding of interest on deferred fees 
and salaries accounts. 

Years Ended December 31, 1995 and 1996
     
     The Company recognized contract research and development revenues of 
$159,076 for the first time in the year ended December 31, 1996.  This revenue 
consisted of a portion of the $200,000 payment under a research support 
agreement between the Company and Genetics Institute, Inc. (received upon 
execution of the agreement), which the Company is recognizing, ratably over 
the 12-month life of the research project.   Revenues also included funds 
received under a  grant from the National Institutes of Health under the Small 
Business Innovation Research ("SBIR") Program.  Prior to this, the Company's 
only revenues had been from interest income and nominal consulting fees for 
services rendered by Ixion personnel to the Biotechnology Development 
Institute.  Revenues under the Genetics Institute Agreement are expected to 
cease in 1997.  Payments of up to $73,000 under the SBIR will continue in 
1997, but will terminate not later than October 1997.

     Other income increased 43% from $3,062 in 1995 to $4,366 in 1996 due 
primarily to an increase in consulting fees for services rendered by Ixion 
personnel to the Biotechnology Development Institute.  

     Operating, general and administrative expenses increased 20% from 
$230,423 in 1995 to $276,642 in 1996,  primarily due to additions to the 
Company's personnel. 

     Research and development expenses increased 199% from $130,984 in 1995 to 
$392,010 in 1996.  This increase was primarily attributable to increases in 
research personnel and the scale of research operations during the year.  The 
Company recorded non-cash compensation expense in the amount of $139,295 in 
1996 related to the issuance of compensatory options and restricted stock.  

     Interest expense increased 77% from $20,927 in 1995 to $37,136 in 1996, 
due primarily to additions to deferred fees and salaries, including deferred 
interest payable to related parties, arising from the deferral of fees and 
salaries in 1993, 1994, 1995, and 1996 by Company officers and consultants, 
and the compounding of deferred interest in those accounts, and to the 
interest on the Company's Unsecured Convertible Notes issued in the last 
quarter of 1996.  

Liquidity and Capital Resources     

     In September 1996, the Company completed a private placement transaction 
in which it sold Unsecured Convertible Notes for an aggregate gross 
consideration of $787,270.  In addition on April, 16, 1996, the Chairman and 
Chief Executive Officer and the President of the Company each entered into an 
agreement to extend the Company up to $25,000 in the form of a bridge loan.  
Interest on the loan is at 8% but can be reset annually, at the election of 
either party, to the prime rate in effect on January 1 of any given year, plus 
3%.  Under these agreements, the Company borrowed a total of $32,100, all of 
which was repaid in cash by the Company on June 14, 1996.  In addition, the 
Chairman, on June 21, 1996, agreed to increase his loan commitment to an 
amount up to $150,000, if necessary, to enable the Company to continue 
operations.  These facilities are available to the Company, but no amounts are 
outstanding at March 31, 1997. The Company does not have any bank financing 
arrangements.  The Company's long-term  indebtedness consists primarily of 
deferred fees and salaries payable to related individuals and a chattel 
mortgage agreement.

     At March 31, 1997, the Company had $373,880  in cash and cash 
equivalents, and working capital of $352,623.              

     On January 1, 1996, the Company purchased laboratory equipment pursuant 
to a chattel mortgage agreement in the amount of $32,309.  The agreement calls 
for monthly payments of $897, commencing August 1, 1996.   The Company 
anticipates making capital expenditures of approximately $40,000 for the year 
ended December 31, 1997, primarily for acquisitions of additional laboratory 
and office equipment.

     For the period March 25, 1993 (date of inception) through March 31, 1997, 
the Company capitalized costs of $164,454 associated with the prosecution of 
various patent applications.  As further research continues and the Company 
acquires additional patent rights, management expects the patents pending 
asset to increase.

     The Company has incurred negative cash flows from operations since its 
inception, and has expended and expects to continue to expend in the future, 
substantial funds to complete its planned product development efforts, 
commence clinical trials, and diversify its technology.  The Company's future 
capital requirements and the adequacy of available funds will depend on 
numerous factors, including the successful commercialization of its HOF Probe 
and IxC-162, progress in its product development efforts, the magnitude and 
scope of such efforts, progress with preclinical studies and clinical trials, 
the cost of contract manufacturing and research organizations, cost of filing, 
prosecuting, defending and enforcing patent claims and other intellectual 
property rights, competing technological and market developments, and the 
development of strategic alliances for the development and marketing of its 
products.  The Company believes that funds generated from the Company's 
operations, together with its existing capital resources would be sufficient 
to meet operating requirements at historical operating levels through December 
31, 1998.  However, the Company requires the proceeds of this Offering and 
interest thereon to meet its planned operating requirements (which accelerate 
product development when compared to historical operating levels) through that 
date.  In the event the Company's plans change or its assumptions change or 
prove to be inaccurate or the proceeds of the Offering prove to be 
insufficient to fund operations (due to unanticipated expenses, delays, 
problems or otherwise), the Company could be  required to seek additional 
financing sooner than currently anticipated.  In addition, the 
Company will be required to obtain additional funds in any event through 
equity or debt financing, strategic alliances with corporate partners and 
others, or through other sources in order to bring its products through 
regulatory approval to commercialization. The terms and prices of any equity 
or debt financings may be significantly more favorable than those of the Units 
sold in this offering.  The Company does not have any material committed 
sources of additional financing, and there can be no assurance that additional 
funding, if necessary, will be available on acceptable terms, if at all.  If 
adequate funds are not available, the Company may be required to delay, scale-
back, or eliminate certain aspects of its operations or attempt to obtain 
funds through arrangements with collaborative partners or others that may 
require the Company to relinquish rights to certain of its technologies, 
product candidates, products, or potential markets.  If adequate funds are not 
available, the Company's business, financial condition, and results of 
operations will be materially and adversely affected.

     Until required for operations, the Company's policy is to invest its cash 
reserves in bank deposits, certificates of deposit, commercial paper, 
corporate notes, U.S. government instruments and other investment-grade 
quality instruments.

Product Research and Development Plan

     The  Company's plan of operation for the 12 months following completion 
of this Offering will consist primarily of research and development and 
related activities including:

  further development of the Company's IPSC research programs aimed at 
proprietary populations of functioning islets for transplantation into 
diabetic patients;  

  continuing the funding of the ongoing discovery program in which the 
Company intends to identify and characterize novel growth factors 
associated with the IPSCs, to discover factors important in islet cell 
differentiation and possible regulation of diabetes and to identify stem 
cell markers to which the Company hopes to produce antibodies useful in 
stem cell isolation; 

  further preclinical development of the Company's diagnostic HOF Probe 
for Oxalobacter formigenes detection, and if successful, the initiation 
of clinical trials; 

  further development of IxC-162, including formulation, product 
characterization, method development, testing (including toxicology), 
cell line characterization, process development, clinical lot 
manufacturing, stability, research protocols, and preclinical studies 
for the Company's proposed products, primarily its oxalate-related 
products;

  continuing the prosecution and filing of patent applications; and 

  hiring additional employees.

     The actual research and development and related activities of the Company 
may vary significantly from current plans depending on numerous factors, 
including changes in the costs of such activities from current estimates, the 
results of the Company's research and development programs, the results of 
clinical studies, the timing of regulatory submissions, technological 
advances, determinations as to commercial potential and the status of 
competitive products.   The focus and direction of the Company's operations 
will also be dependent upon the establishment of collaborative arrangements 
with other companies, and other factors. 
 
     There can be no assurance that the Company will be able to commercialize 
its technologies, or that profitability will ever be achieved.  The Company 
expects that its operating results will fluctuate significantly from quarter 
to quarter in the future and will depend on a number of factors, many of which 
are outside the Company's control.

Recent Accounting Pronouncements

     In February, 1997, the Financial Accounting Standards Board issued 
Statement No. 128, Earnings Per Share.  This statement, which is effective for 
the Company's annual report for the year ended December 31, 1997, establishes 
new requirements for the calculation, presentation, and disclosure of earnings 
per share.  The Company estimates that earnings per share presented in 
accordance with Statement No. 128 would not differ materially from what is 
currently presented.

                                   BUSINESS


                                  The Company

      Ixion Biotechnology, Inc. ("Ixion" or the "Company"), is a development 
stage, discovery research biotechnology company, with several product 
candidates in development.  The Company is the holder of world-wide exclusive 
licenses to patents and pending patents in two key areas: diabetes and 
oxalate-related disorders.  Ixion has executive offices and development 
laboratories (including small scale fermentation, cell culture, and 
purification capabilities) at the Biotechnology Development Institute, a small 
business incubator operated by the Biotechnology Program at the University of 
Florida. 

     Ixion is developing diabetes products based on its Islet Progenitor/Stem 
Cell ("IPSC") technology, including a proprietary line of in vitro (in test 
tube) islet stem cells for use in cell transplantation therapy.  This 
development program is aimed at optimizing the growth of functioning islets or 
islet progenitors in vitro from IPSCs which Ixion has established in cell 
cultures.  The Company believes that successful islet transplantation therapy 
will provide better management of diabetes than conventional treatment with 
insulin and other metabolic regulators.  Conventional treatment can result in 
hyper- and hypo-glycemic episodes which are a major cause of diabetic 
complications.  Ixion's technology is intended to ameliorate this condition by 
implanting functional islets into the body in order to  materially improve 
control of blood glucose levels.

     In addition to developing its cell transplantation therapy, Ixion has an 
ongoing discovery program to identify and characterize IPSCs as well as novel 
growth factors associated with them.  The goal of this program is to discover 
factors important in islet cell differentiation and to identify stem cell 
markers to which the Company hopes to produce antibodies useful in stem cell 
isolation.  All of the Company's potential diabetes products are in the 
discovery research stage.

     Diabetes is a chronic, complex metabolic disease.  Type I (often referred 
to as Insulin Dependent Diabetes or IDD) is characterized by an inability to 
produce insulin due to the destruction of the insulin-producing cells of the 
pancreatic islets of Langerhans.   Type I diabetes also leads to many serious 
conditions ranging from death from diabetic coma or insulin shock, to end 
stage renal disease, blindness, amputations, nerve damage, and cardiovascular 
and periodontal disease.  Over 13 million people in the United States have 
diabetes, of whom five to ten percent (or about one million patients) have 
Type I, the most severe form of the disease, and must take insulin.  An 
additional one and one-half million Type II patients also take insulin.  
Annual expenditures on all forms of diabetes are $112 billion, exceeding 
expenditures on cancer.  The Company estimates that approximately 500,000 
patients in the United States could benefit from IPSC-based therapy.  These 
patients currently spend approximately $10 billion annually in treatment of 
their diabetes.

     The Company is also developing products based on its oxalate technology 
for the diagnosis and treatment of  oxalate-related diseases.  Excess oxalate 
from dietary and metabolic sources plays a role in a variety of disorders 
including kidney stones, hyperoxaluria, cardiomyopathy, cardiac conductance 
disorders, cystic fibrosis, Crohn's disease, renal failure and toxic death, 
and vulvodynia.  The anaerobic intestinal bacteria, Oxalobacter formigenes, 
produces enzymes responsible for oxalate degradation in healthy people, and 
inadequate colonies of them result in reduced ability to degrade oxalate. 

     There are approximately one million kidney stone incidents annually in 
the United States.  Annual expenditures on kidney stone incidents exceed $1.8 
billion.  There are approximately 25,000 cystic fibrosis patients in the 
United States; these patients are at materially increased risk of kidney 
stones as a result of excess oxalate.  There are from 5,000 to 16,000 new 
cases of Inflammatory Bowel Disease annually, resulting in 100,000 
hospitalizations, 60% from Crohn's Disease.  Vulvodynia, a chronic 
multifactorial disorder, believed to be in some degree oxalate-related, 
results in painful and debilitating symptoms affecting the tissue surrounding 
the vagina and urethra.  There are no population studies of the incidence or 
prevalence of vulvodynia, but estimates range as high as 150,000 to 200,000 
U.S. women with this condition. Very few effective treatments, if any, exist 
for these disorders.  

     The most developed product candidate in Ixion's development pipeline is a 
combination diagnostic and therapy for the management of oxalate-related 
disorders.  

     The diagnostic component of the Company's oxalate-related disease 
management product is a DNA probe for the rapid and sensitive detection of 
human O. formigenes (the "HOF Probe").  The current tests for O. formigenes 
are laborious, time consuming, and unreliable, and are limited by (1) the 
difficulties of anaerobic culture methods, (2) the inability to standardize 
and accurately quantitate the presence of the bacteria, and (3) the fact that 
the tests cannot be automated.  In addition, the current tests are not 
sensitive and are poorly suited to a clinical setting.  The HOF Probe, on the 
other hand, can accurately and reliably detect very small numbers of O. 
formigenes, is quantitative, and is capable of automation.  

     The therapeutic component of the Company's oxalate-related disease 
management product is an orally administered product consisting of two enzymes 
normally found in O. formigenes and responsible for oxalate degradation ("IxC-
162").  The Company believes that the administration of  these enzymes will 
greatly diminish the recurrence of calcium oxalate kidney stones and will have 
positive therapeutic effects on other oxalate-related disorders.

     The Company intends to file an Investigational New Drug application with 
the Food and Drug Administration for its IxC-162 enzyme therapy for oxalate-
related diseases and an application under Section 510(k) of the Food, Drug, 
and Cosmetic Act for the HOF Probe, both within 12 months from the date of 
this Prospectus.  See "Business - Government Regulation."

     Ixion is in the development stage, has earned only limited revenues, the 
majority of which have been research and development payments, and has 
incurred accumulated deficits of approximately $1,341,906 from its inception 
through March 31, 1997.  See "Risk Factors."


Industry Description and Outlook  

     In 1996, the U.S. biotechnology industry was composed of approximately 
1,300 companies, public and private.   Sales for the industry as a whole 
increased by 16.0% to $10.8 billion. The public market for biotechnology 
financing was robust during 1996 with the industry raising about $4.5 billion 
compared to $2.2 billion in 1995.  Total financings (excluding milestone 
payments and equity purchases by corporate partners) amounted to $7.5 billion.
For the first six months of 1997, financings have declined to about half of 
the 1996 level.  The biotechnology industry is part of the broader health care 
industry in the United States, which accounts for approximately 14% of the 
country's gross domestic product, or approximately $1 trillion.

     Diabetes.   Diabetes is the world's most common metabolic disease.  In 
1996, there were over 13 million diabetics in the United States.  There are 21 
million diabetics in Europe and as many as 90 million worldwide.  Type I 
patients compose from 5% to 10% of the total number of diabetics in the U.S., 
or approximately one million patients.  An additional 1.5 million Type II 
diabetics also take insulin.  There are approximately 500,000 to 600,000 new 
patients annually in the U.S., of which 35,000 to 50,000 are Type I diabetics.
Approximately 25 percent of the new Type II patients (or approximately 
110,000) will also take insulin.

     Data derived from the National Medical Expenditure Survey database 
indicates that in 1995, diabetes accounted for over 10% of total U.S. health 
care expenditures, or approximately $112 billion.   In 1992, the American 
Diabetes Association estimated that another $47 billion was spent in indirect 
costs, such as lost wages.  Other sources have estimated that indirect costs 
may actually exceed the direct costs.    Complications of the disease include 
amputations of toes and feet, blindness, ulcers, nerve damage and 
cardiovascular, periodontal, and kidney disease.  Approximately 30% to 40% of 
people with Type I diabetes will develop diabetic nephropathy leading to 
kidney dialysis and renal transplants.  Overall, diabetes is the fourth 
leading cause of death in the U.S. 

     Current therapies, including insulin shots, amylin therapy, or oral 
hypoglycemic medication modulate blood glucose, but cannot consistently 
maintain the diabetic's blood glucose at normal levels.  The Diabetes Control 
and Complications trial, a nine-year NIH study, demonstrated that maintaining 
blood glucose at normal levels reduces by approximately 60% the risk of 
development and progression of diabetes complications.  However, there is no 
therapy which supplies insulin in response to changes in blood glucose with 
the speed and precision of functioning islets.  The Company believes that 
approximately 500,000 insulin dependent diabetics are candidates for islet 
transplantation and that successful transplantation of islets capable of 
providing constant glucose control will ameliorate the complications of the 
disease.  Such transplant candidates in the United States spend not less than 
$10 billion on direct care expenditures annually.  It should be noted, 
however, that transplant therapy is an early stage procedure and results, as 
is common for early stage procedures, for the adult islet transplants 
performed to date have been disappointing.   Although there can be no 
assurance, the Company believes that the success rate of transplant therapy 
will improve over time.

     Kidney stones.  Kidney stones are a major health care problem in the 
United States, and a worse one in other parts of the world.  Nearly one in 
every 1000 residents in the United States has been hospitalized for stones, 
and autopsies have revealed that one in every 100 persons have observable 
stone formation in their kidneys.  Between seven and ten of every 1000 
hospital admissions in the United States are for kidney stones; this is 
approximately 248,000 hospital admissions annually.   There are approximately 
one million kidney stone incidents annually, the seventh leading cause of 
physician visits.  Nationwide, approximately 12% of the U.S. population will 
develop stones in their lifetime, but stones are particularly common in the 
region from Virginia to New Mexico, commonly referred to as the "stone belt."  
In other parts of the world, particularly the Middle-East, Asia, and India, 
kidney stones are an even worse problem since hot climates seem to favor stone 
formation.  

     If a stone cannot be passed, it is  surgically removed or shattered by 
extracorporeal shock-wave lithotripsy.  Both treatments are expensive, with 
the average lithotripsy costing $4,617 and surgery costing $8,308 (including 
the hospital stay).  Approximately 30% of patients with kidney stones are 
hospitalized, the remainder pass the stone at home, which, while not 
particularly expensive, is exceedingly painful.  Based on 1993 data, the total 
annual cost of kidney stones in the United States was conservatively estimated 
at $1.83 billion annually.

     Unfortunately, kidney stones usually recur; although for most patients, 
the time between episodes can be years.  The majority of kidney stones are 
made of oxalate, which is an end product of metabolism in the body, and an 
important component of a typical diet.  The intestinal oxalate degrading 
bacteria, Oxalobacter formigenes, plays an important role in oxalate 
homeostasis, both by regulating intestinal absorption of dietary oxalate and 
also its secretion into intestinal lumen from the blood by maintaining a 
transepithelial gradient.  Thus it may be clinically important to screen and 
treat patients with oxalate-associated diseases like kidney stones, enteric 
hyperoxaluria, cardiomyopathy, cardiac conductance disorders, cystic fibrosis, 
Crohn's disease, renal failure and toxic death, and possibly vulvodynia for 
the presence or absence of the bacterium.  Indeed, recent research indicates 
an increased risk of kidney stones in patient populations with significantly 
decreased intestinal colonization by O. formigenes.  This may be particularly 
true of patients with cystic fibrosis, who are at materially increased risk of 
kidney stones as a result of excess oxalate.

     Inflammatory Bowel Disease.  Inflammatory Bowel Disease ("IBD") is a 
general term which covers two primary chronic disorders that cause 
inflammation or ulceration in the small and large intestine: Crohn's disease 
and ulcerative colitis.  The cause of IBD is unknown, with many theories, none 
proven.  One theory is that an agent, like a virus or a bacterium, affects the 
immune system, thus causing an inflammatory reaction in the intestinal wall.  
While there is evidence that IBD is associated with abnormalities in the 
immune system, it is not known whether they are cause or effect of the 
disease.  Many persons with IBD are also hyperoxaluric, suggesting that excess 
oxalate may be a complicating factor in the disease, or may lead to increased 
risk of kidney stones.  In 1987, the latest data available, the number of new 
cases of IBD in the United States annually ranged from two to six per 100,000 
of population.  There were about 100,000 hospitalizations annually, 
approximately 64% for Crohn's. 
     
     Vulvodynia.  Vulvar vestibulitis syndrome ("vulvodynia") is a complex, 
multifactorial disorder with painful and debilitating symptoms affecting the 
tissue surrounding the vagina and urethra, including intense burning, itching, 
and inflammation.  In chronic cases it is very disruptive of a person's life.  
Recognition of this condition as a significant, physiological syndrome 
appeared in medical journals only a decade ago.  There are no population 
studies of the incidence or prevalence of vulvodynia although the condition 
may affect from 150,000 to 200,000 American women.  Because the cause is often 
unknown, treatments have been aimed at symptoms and include xylocaine, 
acupuncture, hypnotherapy, interferon injections, and, as a last resort in 
chronic cases, surgery.  Recent research suggests that vulvodynia is 
associated with oxalate, with some investigators reporting significant 
improvement following control of dietary oxalate.

     Other Oxalate Related Markets.  Two additional products which could make 
use of Ixion's oxalate technology include improved kidney dialysis devices and 
an improved urological catheter.  As of 1995, there were approximately 175,000 
U.S. hemodialysis patients and approximately 300,000 more in Europe and Japan.
The use of the Ixion oxalate technology could significantly reduce the time 
that patients spend in dialysis by increasing the efficiency of oxalate 
removal during the process.  

     The market for urological drains (catheters) was $675 million in 1995.  
Catheters often foster infection and account for the leading side effect of an 
invasive hospital procedure.  One major cause of catheter infection is the 
build-up of oxalate crystals on the catheter.  The Ixion oxalate technology 
would allow an improved catheter which would inhibit or dissolve encrusted 
oxalate crystals, thus reducing the potential for infection.


Business Strategy

     The Company intends to market its initial diagnostic products, while 
working with strategic partners to take its planned therapeutic products 
through clinical trials into the market.   

     Basic Research.  Ixion has a strategic alliance with the University of 
Florida through affiliation with the Biotechnology Program.   Ixion has used 
and intends to continue to use cooperative research and development agreements 
with the University for basic discovery research.  The University of Florida 
is the tenth largest university in the nation and is the largest research 
institution in the Southeast.  In 1995, it ranked ninth in the United States 
in gross royalties received from patent licenses, and sixteenth in the United 
States in the number of U.S. patents obtained.  

     Technology Evaluation and Development.  The Company plans to use its 
strategic affiliation to seek out, evaluate, license, and develop cutting-edge 
university based biotechnology.  The Company's scientific and business team 
will review early stage academic inventions, identify discoveries which are 
scientifically innovative and commercially promising, obtain licenses from the 
University, and develop the discoveries to add value by confirming the initial 
observations.  Discoveries which support the Company's core technologies will 
be retained for further development; the remainder will be licensed-out to 
generate immediate royalty revenue.


     The University's faculty has only recently begun to engage in commercial 
collaborations in significant numbers, thus many promising commercial 
discoveries have not been exploited, for example, the Company recently 
licensed an anti-microbial patent from two members of the University of 
Florida faculty.  See "Business-Licensed Technology."  In addition, academic 
intellectual property is often embryonic and, therefore, too risky, expensive, 
and time consuming for large pharmaceutical and biotechnology companies to 
acquire and develop.  Ixion, on the other hand, is in a position to perform 
"applied basic" research inexpensively, either in its labs or through 
cooperative research agreements, in order to add value to the technology such 
that it is of greater interest to commercial licensees.  By increasing the 
maturity stage of the technology, Ixion hopes to capture an enhanced return 
upon licensing-out for royalty and milestone payments.  See Figure 1, below.

                                                 development.
                                               Ixion declines license.


               Figure 1 - Ixion Technology Opportunity Strategy

     Ixion intends to continue to develop collaborative arrangements with 
leading researchers at the University of Florida and at other research 
institutions in its core oxalate and diabetes areas to diversify and 
strengthen its intellectual property estate and to establish its reputation 
and credibility in the scientific and medical communities. 

     Collaborative Product Development and Marketing with Established 
Companies.  Ixion plans to develop products in collaboration with other 
companies.  Collaborative agreements may call for Ixion's collaborative 
partners to provide research funds as well as clinical and other support 
during  product development, although Ixion may develop and test ideas 
independently before entering into a collaborative agreement.  The Company 
contemplates that its partners will provide an established and trained 
marketing and sales force, as well as GMP manufacturing experience, clinical 
trial expertise, support for patent prosecution, and other capabilities. 

     Independent Product Development.  The quality of Ixion's scientific team 
also permits independent product development.  Independently developed 
products will provide the Company with the flexibility either to market the 
product directly or enter into agreements with pharmaceutical partners on 
terms more favorable to the Company.  While independent product development is 
riskier than collaborative development, the Company may be able to retain a 
higher proportion of any eventual product revenue stream.  The Company's HOF 
Probe is an example of independent product development.

     Contract Clinical Trial and Manufacturing Services.  Initially, the 
Company has elected to  retain contract vendors to support clinical studies 
and product development.  Moreover, it will not construct its own good 
manufacturing practices ("GMP") manufacturing facilities.   By contracting 
with a qualified manufacturing company, Ixion will be able to obtain immediate 
access to the necessary GMP and regulatory skill base at low entry costs.  The 
Company thus expects to minimize the time to market,  maintain control over 
development candidates, and reduce its financial risk when product risk is the 
greatest.

Product Development 

     The Company's first target products for diabetes will be a population of 
cultured islet or pancreatic cells for use in diabetes treatment, and its 
first target products for oxalate-related diseases will be the HOF Probe and 
the associated enzymatic treatment for oxalate-related conditions.  The 
Company also plans other products that will detect and measure the presence of 
oxalate or Oxalobacter formigenes in urine or blood.  Certain of these 
products may be suitable for use in research applications and, subject to 
certain limitations, would not require FDA approval prior to use in that 
context.  (See "Business - Government Regulation," below.) 

     Genetics Institute Sponsored Research Agreement.  In connection with its 
potential diabetes products, in June 1996, the Company entered into a 
sponsored research agreement with Genetics Institute, Inc. ("GI"), a leading 
biopharmaceutical firm.  The sponsored research agreement relates to the 
Company's IPSC technology and grants GI an option to a right of first 
negotiation for an exclusive world-wide license to the Company's IPSC 
technology and any improvements or developments relating to IPSC technology 
which arise during the term of the agreement.  The Company does not expect 
this agreement to be renewed in 1997, nor that GI will exercise its option.

     Descriptions of Planned Diabetes Products.  Ixion intends to develop 
products to enhance research into the disease of diabetes, as well as 
therapeutic approaches where Ixion's proprietary technology offers unique 
solutions. 

     Islet transplantation to reverse diabetes or reduce insulin dependency 
has been limited by, among other things, immunological attack resulting in 
rapid rejection of transplanted tissue.  In addition to the immunologic 
difficulties, there are significant shortages of human islets suitable for 
transplant or research, with only 4,000 or fewer pancreases available for 
transplant annually.  Xenotransplants using porcine islets face additional 
difficulties, such as the possibility of cross-species viruses.  To date, 
efforts to propagate commercial quantities of islets in vitro (in the test 
tube) from either fetal or adult tissue has had minimal success.  The Company 
believes that a source of reproducible islet cells would significantly improve 
the speed and results of research into transplanted islets.

     Ixion's IPSC technology permits the successful growth of in vitro 
pancreatic-derived, pluripotent (e.g., able to differentiate) islet-producing 
cells from mice.  When  mouse cells were implanted into clinically prediabetic 
mice, the implanted mice were successfully weaned from insulin until they were 
sacrificed for histological studies.  The Company has also been successful in 
propagating human islet cells from children and adult donors as well, but has 
not transplanted such islets at the date of this Prospectus.

     Descriptions of Planned Oxalate Products.  At the present time, there is 
no commercial method of rapidly and easily detecting the presence or absence 
of O. formigenes in the body or of measuring oxalate levels in a patient's 
blood.  The current tests for O. formigenes are laborious, time consuming, and 
unreliable, and are limited by (1) the difficulties of anaerobic culture 
methods, (2) the inability to standardize and accurately quantitate the 
presence of the bacteria, and (3) the fact that the tests cannot be automated.  
In addition, the current tests are not sensitive and are poorly suited to a 
clinical setting.  

     The only commercially available tests for levels of oxalate in the human 
body are currently performed in clinical labs by measuring oxalate 
concentrations in urine.  Available assays for measuring oxalate levels in 
urine also have major drawbacks: the samples require careful processing to 
remove inhibitory substances, the tests are complex and cumbersome, and they 
often fail to provide consistent results.  Accordingly, such tests cannot be 
performed in many hospital labs or in a doctor's office.  Ixion's planned 
oxalate products are designed to address these drawbacks.

     The HOF Probe.  Ixion's oxalate technology consists of cloned, sequenced, 
and expressed genes encoding the oxalic acid degrading enzyme and formate 
degrading enzyme from the intestine dwelling bacteria, Oxalobacter formigenes.  
Ixion's Dr. Sidhu,  in collaboration with Dr. Milton Allison, a member of 
Ixion's Scientific Advisory Board and the discoverer of O. formigenes, has 
used these genes to construct a DNA probe (the "HOF Probe") to detect the 
presence of O. formigenes in easily-collectable stool samples.  O. formigenes 
is a gram negative anaerobe present in humans and other animals.  The role of 
this species in intestinal management of oxalate is supported by findings 
showing significantly decreased intestinal colonization in patient populations 
at increased risk of kidney stones.  Research in this area has been inhibited 
by the difficulty of culturing and detecting the anaerobe.  

     The HOF Probe being developed by Ixion is a significant improvement over 
current tests for O. formigenes and is an important potential addition to 
routine diagnostic testing for several reasons. 

  Ixion's HOF Probe is much easier to perform and provides accurate 
results in a fraction of the time required to culture and test for 
O. formigenes using existing methods.

  Ixion's DNA method relies upon standard DNA techniques and does 
not require anaerobic cultures of the organisms since it provides 
direct detection of DNA extracted from fecal samples and amplified 
using PCR.

  Because it is based upon PCR and subsequent hybridization to 
species-specific sequences, the HOF Probe is simple to perform and 
provides the required level of sensitivity, accuracy, selectivity, 
and throughput necessary for a commercial diagnostic test.

  The HOF Probe is sensitive to the level of 1,000 to 10,000 colony 
forming units/gram of fecal material.  This is approximately 100-
fold lower than the number of colony forming units in fecal 
material of normal, healthy adults.
     
 Ongoing development of the HOF Probe is focused on the following areas:

  Extended evaluation and enhancement of probe specificity with 
respect to other intestinal organisms to assure the absence of 
cross reactivity and misdiagnosis.  Organisms currently being 
evaluated include the following: Eschericia coli, Yersinia spp., 
Shigella spp., Salmonella spp., Vibrio colera, Helicobacter 
pylori, Klebsiella, Giardia lamblia, and Campylobacter spp. 

  Development of probes against clinically important intestinal 
organisms such as those listed above.  These, coupled with the HOF 
Probe, will provide for a panel of clinically important diagnostic 
tests.

  Development of quantitative capability for the HOF Probe and other 
DNA probe diagnostics based upon technologies such as PCR, dot 
blot hybridization, and other technologies.

     The Company expects to file an application under Section 510(k) of the 
Food, Drug, and Cosmetic Act for clearance to market its HOF Probe during 
1997.  There is no assurance that the HOF Probe will qualify for 510(k) 
procedure, in which case the Company will have to file an application for 
premarket approval ("PMA") with the FDA.  If the Company must follow the PMA 
approval route, the approval process may be lengthy.

IxC-162 Enzyme Therapy for Oxalate-Related Disease

     In addition to the HOF Probe and other potential diagnostic products 
described above, Ixion is developing IxC-162, an orally administered 
therapeutic product consisting of two enzymes normally found in O. formigenes: 
oxalo-CoA decarboxylase ("oxc") and formyl-CoA transferase ("frc").  The 
enzymatic therapy is based upon the re-establishment of oxalate degrading 
mechanisms in the body. IxC-162 is targeted at oxalate-related disorders 
including kidney stones, enteric hyperoxaluria, oxalosis, cardiomyopathy, 
cardio conductance disorders, cystic fibrosis, Crohn's disease, and possibly 
vulvodynia.  Very few satisfactory treatments currently exist for these 
disorders.  

     Both the oxc and frc enzymes have been successfully cloned into E. coli 
and expressed in active form as verified using activity assays developed by 
Ixion's scientists.  Physicochemical analysis such as SDS-PAGE, IEF, and N-
terminal sequence analysis has been completed, further verifying the correct 
identity of these proteins.  Ixion has grown the recombinant E. coli to 80 
liter scale and has purified the oxc and frc enzymes for use in a variety of 
preclinical studies including (1) additional physicochemical characterization, 
(2) formulation and drug delivery, and (3) animal studies.  The Company is 
also purifying the native form of the oxc and frc enzymes from O. formigenes,  
to provide comparative data to the recombinant versions.  The Company has not 
determined whether the recombinant or native enzymes will be used 
therapeutically.  The current intention is to file an IND for the IxC-162 
enzymatic therapy for oxalate-related disorders in early 1998.

At the date of this Prospectus, the HOF Probe has been performed in 
preclinical studies by Ixion lab personnel on over 300  human samples from 
varied populations in the Ukraine, Germany, the United States, and India.  The 
results of those studies include the following:

  Cystic Fibrosis.  Oxalate kidney stones are a known complication of 
cystic fibrosis.  The incidence in cystic fibrosis populations over 12 
years old approaches 3% to 4% as compared to 0.2% in normal populations.  
Renal autopsies show >90% nephrocalcinosis.  In an Ixion sponsored 
clinical study conducted in collaboration with collaborators at 
Northwestern University, the University Children's' Hospital, Cologne, 
Germany, and University Children's Hospital, Halle, Germany, 40 (18 male 
and 22 female) cystic fibrosis patients (aged three to 35 years) were 
examined for colonization with Oxalobacter formigenes.  33 of the 40 
patients were non-colonized, and of these, 18 were hyperoxaluric and 
eight had urinary oxalate levels in the upper normal range.  The seven 
patients who were colonized with O. formigenes all showed normal levels 
of urinary oxalate.

  Recurrent Stone Formers.  In another currently ongoing study on O. 
formigenes colonization in adult calcium oxalate stone formers, 
preliminary data have revealed that the majority of recurrent stone 
formers (five or more stone episodes) are non-colonized with this 
bacteria.  Studies in the literature suggesting a decrease in the colony 
forming units of O. formigenes in patients with oxalate calculi, rather 
than complete non-colonization, has led to the development by Ixion of a 
Quantitative- PCR HOF Probe.  The Quantitative-PCR HOF Probe is now 
being used in additional preclinical work to detect and quantitate O. 
formigenes in oxalate stone formers to determine if the number of Colony 
Forming Units is a relevant risk factor.

  Vulvodynia.  A new preclinical study has just begun in cooperation with 
the Diagnostic Reference Laboratory at the Shands Hospital at the 
University of Florida to examine 25 to 40 vulvodynia patients for 
colonization with Oxalobacter formigenes.  


     Over 65 percent of kidney stones are calcium-oxalate stones, and excess 
oxalate is implicated in other diseases as set forth above. Oxalate is present 
in many common foods, including tea, broccoli, and spinach.  O. formigenes is 
involved in degradation of dietary oxalate and its secretion from plasma into 
the gut.  The Company believes that a robust colony of O. formigenes prevents 
recurrent calcium-oxalate kidney stone formation and may ameliorate other 
disease states.  Management believes that Ixion is the only company world-wide 
which is examining the role of O. formigenes in human and animal disease 
states.


     Blood Oxalate Assay.  The combination of the oxc and frc enzymes and 
cofactors also serve as the basis for a planned blood oxalate assays.  The 
recurrence rate of calcium oxalate kidney stone formation is very high, with 
hyperoxaluria as the major predisposing factor to stone formation.  Accurate 
measurements of blood oxalate levels, together with the presence or absence of 
O. formigenes, are important requirements for predicting the risk of 
calculogenesis in an individual.  Development is planned in 1998 on an 
additional oxalate product: a blood oxalate assay, to be designed for clinical 
use by hospitals, independent labs, and doctors.  

     The following table summarizes the current status of the Company's 
oxalate product research and development program.

Licensed Technology

     The Company has been licensed, on an exclusive world-wide basis, 
commercial rights under one issued U.S. patent, issued February 1997, relating 
to its oxalate technology, and one patent allowed June 1997, relating to its 
IPSC technology, as well as several pending patent applications, divisional 
applications, continuations, and continuations-in-part, held by the University 
of Florida Research Foundation, Inc. ("UFRFI"), the technology transfer 
organization of the University of Florida.  The licensed technology relates to 
two areas:  in vitro grown Islet Progenitor/Stem Cells ("IPSCs") for curing 
diabetes, and materials and methods for detection of oxalate and Oxalobacter 
formigenes.  The licenses are subject to nonexclusive licenses granted to the 
U.S. government, which is commonly required when the government has funded a 
portion of the research leading to the patent applications.

     The license agreements pursuant to which the Company has the rights to 
these patent applications require UFRFI to file and prosecute the patents 
relating to the technology licensed to the Company, the costs of which are 
required to be reimbursed by the Company, and to take all steps to defend such 
patent rights.  If UFRFI fails to take any such action, the Company has the 
right to defend such rights at its own expense.

     The Company and UFRFI entered into a Patent License Agreement relating to 
materials and methods for detection of oxalate on January 11, 1996, and 
another Patent License Agreement relating to in vitro grown IPSCs for curing 
diabetes on February 17, 1995 (the "University Patent Licenses").  Except for 
royalty rates and certain other immaterial differences, the terms of these 
licenses are substantially identical.  Pursuant to the University Patent 
Licenses, UFRFI licensed its rights under patent applications on an exclusive, 
worldwide basis to the Company.  The Company has rights under the University 
Patent Licenses to all possible uses of the patent applications, any patents 
issued from such applications, any divisionals and continuations of such 
applications, and to any claims of U.S. and foreign continuation-in-part 
applications, and of the resulting patents, which are directed to subject 
matter specifically described in such applications.  The University Patent 
Licenses are subject to certain diligence milestones related to 
commercialization of products. 

     Under the University Patent Licenses, the Company paid a license issue 
fee,  is obligated to pay royalties on net sales by Ixion or its sublicensees 
of licensed products or licensed processes, and must reimburse UFRFI for 
patent costs incurred in prosecuting the patent applications.  There are no 
minimum annual royalties.  The Company is also obliged to obtain product 
liability insurance prior to the sale for commercial purposes of licensed 
products.  There is no assurance that the Company will be able to obtain such 
insurance on reasonable terms.  See "Risk Factors - Risk of Product Liability; 
Insurance."

     A number of pharmaceutical companies, biotechnology companies, 
universities and research institutions, and individuals have filed patent 
applications or received patents to technologies that are similar to the 
technologies licensed by the Company.  The Company is aware of certain patent 
applications previously filed by and patents already issued to others that 
could conflict with patents or patent applications licensed to the Company, 
either by claiming the same methods or compounds or by claiming methods or 
compounds that could dominate those licensed to the Company.  In addition, 
there can be no assurance that the Company is aware of all patents or patent 
applications that may materially affect the Company's ability to make, use, or 
sell any products.  United States patent applications are confidential while 
pending in the United States Patent and Trademark Office ("PTO"), and patent 
applications filed in foreign countries are often first published six months 
or more after filing.  Any conflicts resulting from third party patent 
applications and patents could significantly reduce the coverage of the 
patents or patent applications licensed to the Company and limit the ability 
of the Company to obtain meaningful patent protection.  If patents are issued 
to other companies that contain competitive or conflicting claims, the Company 
may be required to obtain licenses to these patents or to develop or obtain 
alternative technology.  There can be no assurance that the Company will be 
able to obtain any such license on acceptable terms or at all.  If such 
licenses are not obtained, the Company could be delayed in or prevented from 
the development or commercialization of its product candidates, which would 
have a material adverse effect on the Company.
 
     The Company is aware of potentially significant risks regarding the 
patent rights licensed by the Company relating to Islet Progenitor/Stem Cells 
and to its oxalate technology, particularly bacterial oxalyl-CoA 
decarboxylase, an enzyme used in the Company's proposed oxalate-related 
products including the HOF Probe and the IxC-162 enzyme therapy.  The Company 
may not be able to commercialize its proposed diabetic products based on its 
method of proliferating IPSCs in vitro or its proposed oxalate-related disease 
management products, both due to patent rights held by third parties other 
than the Company's licensors. As a result, the positions of the Company and 
its licensors with respect to the use of IPSCs or products containing oxalyl-
CoA decarboxylase are uncertain and involve legal and factual questions that 
are unknown or unresolved.  If any of these questions is resolved in a manner 
that is not favorable to the Company's licensors or the Company, the Company 
would not have the right to commercialize products relating to certain aspects 
of IPSC technology or products containing oxalyl-CoA decarboxylase in the 
absence of a license from one or more third parties, which may not be 
available on acceptable terms or at all.  The Company's inability to 
commercialize any of these products would have a material adverse effect on 
the Company.   

     As mentioned above, the Company obtained its rights to IPSCs under a 
license from the University of Florida Research Foundation, Inc. ("UFRFI") in 
February 1995.   In 1994 and 1995, UFRFI filed in the United States and 
thereafter in numerous foreign countries patent applications covering IPSCs.

     In 1981, the Ontario Cancer Institute filed a patent application in the 
United States and was issued a patent in 1984 covering a method for producing 
pancreatic islet-like structures having histology and insulin-producing 
properties corresponding to those of fetal pancreatic islets and islets from 
adult animals maintained in culture, based on discoveries by Michael Archer 
(the "Archer Patent").  The patented method is similar, but not identical, to 
the Company's IPSC technology.  The Archer Patent was licensed to 
CytoTherapeutics, Inc. in 1991.  CytoTherapeutics may have filed patent 
applications in foreign countries based upon the Archer Patent and may have 
additional patent applications on the same general subject matter pending in 
the United States.  CytoTherapeutics' 50%-owned Swiss subsidiary, Modex 
Therapeutics SA, has licensed certain technology from CytoTherapeutics, which 
may include the Archer Patent, with the intent of developing treatments for 
Type I diabetes.

     The Company is also aware that in 1993, Human Cell Cultures, Inc., filed 
an application in the United States and thereafter in foreign jurisdictions, 
covering a cell culturing method and medium to form pancreatic "pseudotissues" 
composed of "pseudoislets" to treat blood sugar disorders in mammals, based on 
discoveries by Hayden Coon (the "Coon Patent Application").  The Coon Patent 
Application covers a method which is also similar, but not identical, to the 
Company's IPSC technology.  At the date of this Prospectus, the Company is not 
aware of any U.S. or foreign patents which have issued relating to the Coon 
Patent Application.  However, such patents may have been issued and there may 
have been additional patent applications filed in the United States or foreign 
countries based upon the Coon Patent Application.

     In the United States, one must be the first to invent a subject matter in 
order to be  entitled to patent protection on that invention.  With respect to 
patent applications filed prior to January 1, 1996, United States patent law 
provides that if a party invented a technology outside the United States, then 
for purposes of determining the first to invent the technology, that party is 
deemed to have invented the technology on the earlier of the date it 
introduced the invention in the United States or the date it filed its patent 
application.  In foreign countries, the first party to file a patent 
application on an invention, not the first to invent the subject matter, is 
entitled to patent protection on that invention, assuming that the invention 
meets the other requirements for patentability. There can be no assurance that 
the owners of the Archer Patent nor the owners of the Coon Patent Application 
will not make challenges to any UFRFI patents or patent applications relating 
to IPSCs, or that UFRFI will succeed in defending any such challenges.  There 
can be no assurance that the sale of IPSC products by the Company would not be 
held to infringe United States and foreign patent rights of the owners of the 
Archer Patent or the Coon Patent Application.  Under the patent laws of most 
countries, a product can be found to infringe a third party patent either if 
the third party patent expressly covers the product or method of treatment 
using the product, or in certain circumstances, if the third party patent, 
while not expressly covering the product or method, covers subject matter that 
is substantially equivalent in nature to the product or method.  If it is 
determined that products derived from the Company's IPSC technology infringe 
the Archer Patent or infringe a patent, if any, issued pursuant to the Coon 
Patent Application, the Company would not have the right to make, use, or sell 
its IPSC products in one or more countries in the absence of a license from 
the owners of such patents.  There can be no assurance that the Company could 
obtain a license from such owners on acceptable terms or at all.       

     As mentioned above, the Company obtained its rights to its oxalate 
technology under a license from UFRFI in January 1995.   In 1994 and 1995, 
UFRFI filed in the United States and thereafter in numerous foreign countries 
patent applications covering its oxalate technology with claims which cover 
the Company's HOF Probe and its IxC-162 therapy for oxalate-related disorders, 
both of which involve the use of an enzyme called oxalyl-CoA decarboxylase 
derived from the anaerobic bacteria, Oxalobacter formigenes.  

     In June, 1995, Human Genome Sciences, Inc., filed a patent application in 
the United States, and thereafter in foreign countries, relating to a claimed 
human oxalyl-CoA decarboxylase and the DNA(RNA) encoding such polypeptide, as 
well as a procedure for producing such polypeptide and for producing an 
antibody relating to such polypeptide for use in the treatment of calcium 
oxalate kidney stones and hyperoxaluria.  A U.S. Patent was issued on June 3, 
1997 (the "HGS Patent").  The HGS Patent purports to relate to a human version 
of oxalyl-CoA decarboxylase which is stated to be 50% to 60% homologous to the 
oxalyl-CoA decarboxylase from the anaerobic bacteria, Oxalobacter formigenes. 
If the use of the Company's bacterial oxalyl-CoA decarboxylase is found to 
infringe the patent owned by Human Genome Sciences, then the Company would not 
have the right to sell such products in one or more countries without a 
license from Human Genome Sciences.  There can be no assurance that the 
Company would be able to obtain a license from Human Genome Sciences on 
acceptable terms or at all.
 
     Litigation, which could result in substantial cost to the Company, may 
also be necessary to enforce any patents to which the Company has rights or to 
determine the scope, validity, and enforceability of other parties' 
proprietary rights, which may affect the Company's product candidates and 
technology.  United States patents carry a presumption of validity and 
generally can be invalidated only through clear and convincing evidence.  The 
Company's licensors may also have to participate in interference proceedings 
declared by the PTO to determine the priority of an invention, which could 
result in substantial cost to the Company.   There can be no assurance that 
the Company's licensed patents would be held valid by a court or 
administrative body or that an alleged infringer would be found to be 
infringing.  Further, with respect to the technology licensed by the Company 
from UFRFI, UFRFI is primarily responsible for any litigation, interference, 
opposition, or other action pertaining to patents or patent applications 
related to the licensed technology, and the Company is required to reimburse 
it for the costs it incurs in interference or opposition.  As a result, the 
Company generally does not have the ability to institute or determine the 
conduct of any such patent proceedings unless UFRFI does not elect to 
institute or elects to abandon such proceedings.  In cases where UFRFI elects 
to institute and prosecute patent proceedings, the Company's rights will be 
dependent in part upon the manner in which UFRFI conducts the proceedings. 
UFRFI could, in any of these proceedings that it elects to initiate and 
maintain, elect not to vigorously pursue or defend or to settle such 
proceedings on terms that are not favorable to the Company.  An adverse 
outcome in any patent litigation or interference proceeding could subject the 
Company to significant liabilities to third parties, require disputed rights 
to be licensed from third parties, or require the Company to cease using such 
technology, any of which could have a material adverse effect on the Company.  

     No assurance can be given that any existing patent application, or any 
future patent application will issue or that any patents, if issued, will 
provide the Company with adequate patent protection with respect to the 
covered products, their uses, technology, or processes.  In addition, under 
its licenses with UFRFI, the Company is required to meet specified diligence 
requirements to retain its license of these patents.  No assurance can be 
given that the Company will satisfy any of these requirements.  See "Risk 
Factors - Uncertainty Regarding Patents and Proprietary Rights."

     In January 1997, Ixion entered into a patent license agreement obtaining 
exclusive rights to the issued patent of Dr. Randy S. Fischer and Dr. Roy A. 
Jensen, faculty members at the University of Florida, for identifying a 
difference which exists between the metabolic pathway of a microbial or plant 
target organism and a non-target host specie and then preparing a control 
agent which perturbs the metabolic pathway of the target without significantly 
perturbing the metabolic pathway of the host.  This patent may be useful in 
the development of microbicides for drug resistant pathogens such as 
staphyloccus, enterococcus, and neisseria.  Under the Fischer/Jensen license 
agreement, the Company paid a license issue fee and is obligated to pay 
royalties on net sales by Ixion or its sublicensees.  There are no minimum 
annual royalties.



Patents and Trade Secrets

     Dr. Peck, as an employee of the University of Florida, is bound by the 
terms of the University's patent policy, which requires that any invention 
conceived of or developed in the area in which he is employed belongs 
exclusively to the University (subject to certain rights of the federal 
government and to Ixion's rights under the consulting agreement it has with 
him).  See "Management - Consulting Agreement With Dr. Peck" and "Business - 
Government Regulation - Florida Conflicts of Interest."

     It is the Company's policy to require its directors, material investors, 
employees, consultants, outside scientific collaborators, and sponsored 
researchers, and other advisors to execute confidentiality agreements upon 
investment or upon the commencement of employment or consulting relationships 
with the Company.  These agreements provide that all confidential information 
developed or made known to the individual during the course of his or her 
relationship with the Company is to be kept confidential and not disclosed to 
third parties.   Ixion also requires signed confidentiality or material 
transfer agreements from any company that is to receive confidential data or 
proprietary compounds.  In the case of employees and consultants, the 
confidentiality agreements also generally provide that all inventions 
conceived by the individual while rendering services to the Company shall be 
assigned to Ixion as the exclusive property of Ixion (subject, in the case of 
Dr. Peck, to the prior rights of the University of Florida).  There can be no 
assurance, however, that these agreements will provide meaningful protection 
or adequate remedies for the Company's trade secrets or other proprietary 
information in the event of an unauthorized disclosure or will be effective to 
assign inventions.

     Certain of the Company's research is being funded in part by Small 
Business Innovation Research grants ("SBIRs")  and may be funded by Small 
Business Technology Transfer Research grants ("STTRs").  In connection with 
such funding, the U.S. Government will have certain rights (the "Government 
Rights") in the technology developed with the funding.  The Government Rights 
include a non-exclusive, paid-up, worldwide license under such inventions for 
any governmental purpose.  In addition, the Government has the right to 
require the Company to grant an exclusive license under any of such inventions 
to a third party if the government determines that (i) adequate steps have not 
been taken to commercialize such inventions, (ii) such action is necessary to 
meet public health or safety needs, or (iii) such action is necessary to meet 
requirement for public use under federal regulations.  Federal law requires 
any licensor of an invention that was partially funded by federal grants 
(which is the case with the inventions licensed by Ixion from UFRFI) to obtain 
a covenant from its exclusive licensee to substantially manufacture products 
using the invention in the United States, although this covenant is subject to 
a discretionary waiver by the government.  In addition, the Company's licenses 
from UFRFI are also subject to Government Rights.

     In order to produce or use the HOF Probe in its current formulation or to 
produce the Blood Oxalate Assay (and other immunodiagnostic products) in 
commercial quantities for resale, it may be necessary to license certain 
rights from Roche Molecular Systems, Inc., the holder of patents on a nucleic 
acid amplification process known as the polymerase chain reaction ("PCR") 
process.  If Ixion finds it necessary to use PCR to produce commercial 
quantities, it will enter into such a license with Roche which makes non-
exclusive licenses generally available.  The Company does not anticipate that 
the terms of such license will have a materially adverse effect on the 
Company.

Competition

     The biotechnology and pharmaceutical industries are characterized by 
rapidly evolving technology and intense competition.  The Company's 
competitors include major pharmaceutical, chemical, and specialized 
biotechnology companies, many of which have larger R&D budgets, as well as 
substantially greater experience in developing products, in obtaining 
regulatory approvals, and in manufacturing and marketing diagnostic and 
pharmaceutical products.  In addition, many biotechnology companies have 
formed collaborations with large, established companies to support research, 
development, and commercialization of products that may be competitive with 
those of the Company.  Academic institutions, governmental agencies, and other 
public and private research organizations are also conducting research 
activities and seeking patent protection and may commercialize products on 
their own or through joint ventures.  

     The Company's products under development are expected to address a broad 
range of markets.  The Company's competition will be determined in part by the 
potential indications for which the Company's products are developed and 
ultimately approved by regulatory authorities.  See "Business - Government 
Regulation."  In addition, the first pharmaceutical product to reach the 
market in a therapeutic or preventive area is often at a significant 
competitive advantage relative to later entrants to the market.  Accordingly, 
the relative speed with which Ixion or its future corporate partners can 
develop products, complete the preclinical and clinical trials and approval 
processes, and supply commercial quantities of the products to the market are 
expected to be important competitive factors.  The Company's competitive 
position will also depend on its ability to attract and retain qualified 
scientific and other personnel, develop effective proprietary products, 
develop and implement production and marketing plans, contract for and manage 
third-party service providers, obtain and maintain patent protection, and 
secure adequate capital resources.  The Company expects its products, if 
approved for sale, to compete primarily on the basis of product efficacy, 
safety, patient convenience, reliability, value, and scope of patent rights.  
See "Risk Factors - Intense Competition."

Government Regulation

     In the United States, the Food and Drug Administration ("FDA") regulates 
distribution, manufacture, labeling, and promotion of drugs, medical devices, 
and biologics.  In addition, manufacturers of these products are subject to 
other federal, state, and local environmental and safety laws and regulations.
Governments in other countries may impose additional requirements.

     FDA Authorization to Market.  Drugs, medical devices, or biologics may 
not be manufactured for commercial use in the United States unless they have 
FDA authorization.  Obtaining FDA authorization to market a regulated product 
generally involves the submission of preclinical, product characterization, 
clinical, and manufacturing information.  The process can take a number of 
years and the expenditure of significant resources, and there is no guarantee 
that the FDA will ever authorize marketing of the product.

     Drugs and Biologics.  Some of the Company's planned products, such as the 
diabetes treatment products, will be considered drugs, devices, biologics or a 
combination of these designations.  The Food, Drug, and Cosmetic Act ("FDCA") 
and the Public Health Service Act ("PHSA") provide that drugs and biologics 
may not be commercially distributed within the United States unless they have 
been approved by the FDA.  The process required by the FDA before drugs and 
biologics may be marketed in the United States generally involves five steps: 
(1) preclinical laboratory and animal testing, (2) submission to the FDA of an 
Investigational New Drug ("IND") application which must be effective prior to 
the initiation of human clinical studies, (3) adequate and well-controlled 
clinical trials to establish safety and efficacy for its intended use, (4) 
submission to the FDA of an New Drug Application ("NDA"), Biologics License 
Application, ("BLA"), or Product License Application ("PLA")/ Establishment 
License Application ("ELA"), and (5) review and approval of the NDA, BLA, or 
PLA/ELA by the FDA.

     Preclinical testing covers laboratory evaluation of product chemistry and 
formulation as well as animal studies to assess the safety, pharmacology, 
toxicology, and efficacy of the product.  The results of these tests are 
submitted to the FDA as part of the IND.  If a company is not notified by the 
FDA within 30 days of submission of the IND, Phase I clinical trials may be 
initiated.  Clinical trials are typically conducted in three sequential 
phases, although the phases may overlap.  Phase I represents the initial 
administration of the drug or biologic to a small group of humans, healthy 
volunteers, to test for safety, dosage tolerance, absorption, distribution, 
metabolism, excretion, and clinical pharmacology.  Phase II involves studies 
in a small number of patients to assess the efficacy of the product, to 
ascertain dose tolerance and the optimal dose range, and to gather additional 
data relating to safety and potential adverse effects.  Once an 
investigational drug is found to have some efficacy and an acceptable safety 
profile in the targeted patient population, Phase III studies are initiated to 
establish safety and efficacy in an expanded patient population and multiple 
clinical study sites.  The FDA reviews both the clinical plans and the results 
of the trials and may request that the Company discontinue or expand the 
trials at any time if there are significant safety issues.

     The results of the preclinical tests and clinical trials of drugs and 
biologics are submitted to the FDA in the form of an application for an NDA 
(in the case of a drug), BLA, or PLA (in the case of a biologic).  Additional 
information, including additional animal studies or clinical trials, may be 
requested during the FDA review period that may extend the review process and 
delay marketing approval.  There can be no assurance that the FDA will 
authorize marketing of the product, or that it will do so in a timely manner.  
For certain biologics, the manufacturer must also apply for and obtain an 
establishment license (ELA), which may be granted following a review and 
inspection of the manufacturing procedures, equipment, and facilities involved 
in manufacturing the product.  For drugs and biologics reviewed via a BLA, the 
manufacturer must also pass a premarket inspection of its compliance with good 
manufacturing practices.  After FDA approval of the NDA, BLA, or PLA for the 
initial indications, further clinical trials may be necessary to gain approval 
for the labeling of the product for additional indications.

     Medical Devices.  Many of the Company's planned products (e.g., the in 
vitro diagnostic products such as the HOF Probe, or the populations of in 
vitro grown islets for transplantation therapy) will be considered medical 
devices or a combination of devices and biologics.  Pursuant to the FDCA, the 
FDA regulates the clinical testing, manufacture, labeling, distribution, and 
promotion of medical devices.   The FDCA further provides that, unless 
exempted by regulation, medical devices may not be commercially distributed in 
the United States unless they have been approved or cleared by the FDA.  

     In the United States, medical devices are classified into one of three 
classes (class I, II, or III), on the basis of the controls deemed necessary 
by the FDA to reasonably assure their safety and effectiveness.  Under FDA 
regulations, class I devices are subject to general controls (for example, 
labeling, premarket notification, and adherence to GMPs), and class II devices 
are subject to general and specific controls (for example, performance 
standards, postmarket surveillance, patient registries and FDA guidelines).  
Generally, class III devices are those which must receive a PMA by the FDA to 
ensure their safety and effectiveness (for example, life sustaining, life-
supporting, and implantable devices, or new devices which have not been found 
substantially equivalent to legally marketed devices).  

     There are two review procedures by which medical devices can receive such 
approval or clearance.  Some products may qualify for clearance under a 
Section 510(k) ("510(k)") procedure, in which the manufacturer provides a 
premarket notification that it intends to begin marketing the product, and 
shows that the product is substantially equivalent to another legally marketed 
product (i.e., that it has the same intended use and is as safe and effective 
as a legally marketed device and does not raise different questions of safety 
and effectiveness than does a legally marketed device).  In some cases, the 
submission must include data from human clinical studies.  Marketing may 
commence when the FDA issues a clearance letter finding such substantial 
equivalence.

     If the medical device does not qualify for the 510(k) procedure (either 
because it is not substantially equivalent to a legally marketed device or 
because it is a Class III device required by the statute and implementing 
regulations to have an approved application for premarket approval), the FDA 
must approve a premarket approval ("PMA") application before marketing can 
begin.  PMA applications must demonstrate, among other matters, that the 
medical device is safe and effective.  A PMA application is typically a 
complex submission, usually including the results of preclinical and clinical 
studies, and preparing an application is a detailed and time-consuming 
process.  Once a PMA application has been submitted, the FDA's review may be 
lengthy and may include requests for additional data.  The manufacturer must  
also pass a premarket inspection of its compliance with good manufacturing 
practices.  There can be no assurances that the FDA will authorize marketing 
of the product under a 510(k) or a PMA, or that it will do so in a timely 
manner.  After FDA approval of the initial indication, further clinical trials 
may be necessary to gain approval of the product for additional indications.

     Clinical investigations of most devices are subject to the 
investigational device exemption ("IDE") requirements, which usually involve 
FDA review of the investigation before it may begin.  Clinical investigations 
of many in vitro diagnostic ("IVDs") tests are exempt from the IDE 
requirements, provided the testing meets certain exemption criteria, including 
labeling as an Investigational Use Only ("IUO") product.  In addition, IVDs 
may be distributed for research use only ("RUO"), provided they are intended 
for laboratory research and labeled for research use.  Pursuant to current FDA 
policy, manufacturers of IVDs for IUO or RUO are encouraged by the FDA to 
establish a certification program under which these IVDs are distributed to or 
utilized only by individuals, laboratories, or health care facilities that 
have provided the manufacturer with a written certification of compliance 
indicating that the IUO or RUO product will be restricted in use and will, 
among other things, meet institutional review board and informed consent 
requirements.
     
     The Company's Products.  The Company's HOF Probe and Blood Oxalate Assays 
will be distributed initially for research use and will not require FDA review 
prior to distribution for those uses.  To market these products for diagnostic 
use, the Company intends to request authorization under the 510(k) procedure 
for the HOF Probe and perhaps the Blood Oxalate Assay.  PMAs may, however, be 
required for each of these products.  The Company's diabetes treatment 
products will require a BLA or PLA/ELA before they may be commercially 
distributed, and these products may be clinically tested only after the FDA 
has been provided an IND which may be reviewed within the FDA by the Center 
for Biologics and Research (CBER) and the Center for Drug Evaluation and 
Research (CDER).  Additionally the Company may be required to register its 
diabetes treatment products as a prerequisite to commercial distribution.  
There can be no assurance that the FDA will accept the Company's views on the 
regulatory status of its products, or that the FDA will authorize marketing or 
clinical investigation of any product, or that it will do so in a timely 
manner.  Additional studies or other information may be requested during the 
FDA review period that may delay marketing authorization.  Marketing 
authorizations, if granted, may include significant limitations on the uses 
for which a product can be marketed.  The law or government regulations may 
change in ways that could prevent or delay marketing authorization for the 
Company's products.  Delays in receipt of, failure to receive, or loss of 
previously received approvals could have a material adverse effect on the 
Company's business, financial condition, and results of operations.

     Other FDA Obligations.  Each manufacturing facility for drugs, medical 
devices, or biologics, must be registered with the FDA, and the products 
manufactured at that facility must be listed with the FDA.  A manufacturer's 
quality control and manufacturing procedures must conform on an ongoing basis 
with good manufacturing practices.  Certain adverse effects and product 
malfunctions must be reported to the FDA.  Product labeling and advertising 
must comply with FDA requirements.  In some cases, postmarket testing may be 
required, or other requirements imposed.  Complying with these requirements 
requires substantial time, money, and effort.  The Company intends to rely on 
its strategic partners for assistance with these matters.

     FDA Enforcement.  The FDA inspects manufacturers of drugs, medical 
devices, and biologics on a regular basis.  Failure to comply with applicable 
requirements can, among other consequences, result in civil penalties, 
injunctions, suspensions, and losses of regulatory approvals, product recalls, 
seizure of products, refusal to allow the Company to enter into supply 
contracts with the government, and criminal prosecution.  The Company intends 
to rely on its strategic partners for assistance with these matters.

     Non-U.S. Marketing.  For marketing outside the United States, the Company 
is also subject to foreign regulatory requirements.  Requirements governing 
the conduct of clinical trials, product licensing, pricing, and reimbursement 
vary widely from country to country.  The time required to obtain approvals by 
foreign countries may be longer or shorter than that required for FDA 
approval, and regulatory requirements for foreign countries may differ 
significantly from those of the FDA.  In some cases, products may not be 
exported until FDA approval is obtained.  The Company intends to rely on its 
strategic partners both in the United States and abroad for assistance with 
these matters.

     Florida Conflicts of Interest.  Because Dr. Peck, the Company's Chief 
Scientist, and Dr. Schuster and Dr. Khan, members of the Company's Scientific 
Advisory Board, are employees of the Florida State University System, they, 
and consequently the Company, are subject to Florida statutes relating to 
conflicts of interest.  In order for Ixion to conduct business with the 
University (including licensing University technology or entering into 
CRADAs), it is necessary to obtain and maintain an exemption for Dr. Peck from 
the application of the Florida conflict of interest statutes, and to obtain 
approvals for outside activities for Dr. Schuster and Dr. Khan.  

     Dr. Peck obtained his initial exemption from the Florida conflict of 
interest statutes on January 5, 1995.  The exemption was issued pursuant to a 
monitoring plan which requires the Company, among other things, to promptly 
disclose every material transaction between the Company and any employee of 
the University.  Exemptions must be renewed annually at the beginning of each 
academic year (or upon material alterations in the terms of the relations 
between the Company and Dr. Peck) and the process can take up to six or more 
months.  The most recent requests to reconfirm Dr. Peck's exemption were 
timely filed and are pending.  There is no assurance that the exemption will 
be renewed, or that it will be renewed on reasonable terms.

Manufacturing and Marketing 

     The Company has no experience in manufacturing or marketing products on a 
commercial scale. Marketing rights for products may be licensed to corporate 
partners.  Co-marketing arrangements may also be feasible for some products.  
Ixion intends to seek distribution arrangements for its products in other 
countries outside of the United States.  While using third parties for 
distribution or marketing permits the Company to avoid the costs of 
establishing a distribution or marketing network in a particular area, this 
strategy also makes the Company more dependent on the efforts of third 
parties, involves a potential reduction in profit margins, and may complicate 
negotiations and other matters associated with technology licenses.

     Target Markets. Management believes there will be substantial demand for 
the HOF Probe in the research market and by certain specialized kidney, 
nephrogenic, and urologic reference labs.  The target markets for the new 
blood oxalate assay include approximately 5,000 hospital labs, the several 
major independent labs, and the same specialized kidney, nephrogenic, and 
urologic reference labs as for the HOF Probe.  For the use of the HOF Probe, 
the blood oxalate assay, and its IxC-162 enzymes therapy  in the management of 
kidney stones, the Company plans to target the country's approximately 7,300 
in-office urologists.  For the use of the HOF Probe and IxC-162 enzyme therapy 
for managing kidney stone risk in cystic fibrosis patients, the Company plans 
to target the cystic fibrosis treatment centers in the United States.  For the 
use of the HOF Probe and IxC-162 enzyme therapy in the diagnosis and treatment 
of vulvodynia, the Company intends to approach the market through the 35,000 
gynecologists practicing in the United States. 

     Marketing Strategy.  The strategy for marketing IPSC-related products 
will depend on collaborations with third parties with greater marketing 
resources than the Company.

     Kidney stones, while prevalent, are not generally recognized as 
predictable or avoidable by many physicians and their patients.  Consequently, 
the promotional task will be difficult.  To meet this challenge, the Company 
intends to invest in both physician education programs, and, assuming funds 
are available, consumer awareness campaigns.  The Company can reach the 
country's over 7,300 in-office urologists through a direct mail campaign.  In 
addition, working with specialized companies in the urology market, the 
Company proposes to inform urologists about the Company's planned new kidney 
stone disease management products.  In addition, the Scientific Advisory Board 
members and other recognized scientists will be encouraged to write articles 
for peer review scientific journals to stimulate interest and establish 
further credibility in the scientific and medical communities.

     A similar approach will be used to approach the gynecological market for 
the Company's vulvodynia. Products and the cystic fibrosis market for the 
management of kidney stone risk. 

     In each case, the Company intends to participate in urology, nephrology, 
gynecology, and other industry trade meetings and to exploit on-line medical 
databases and its own web site.  Finally, as stated above, the Company intends 
to use third-party sales forces to amplify its efforts.  See "Business - 
Business Strategy."

Facilities

     As an affiliate of the University of Florida's Biotechnology Program, the 
Company has leased approximately 1,900 square feet of equipped laboratory 
space and approximately 500 square feet of administrative office space in the  
business incubator at Progress Park (the University of Florida biotechnology 
industrial park), called the Biotechnology Development Institute.  As a 
resident, the Company shares (at no additional cost) specialized facilities 
such as animal rooms, small-scale fermentation capabilities, and glass washing 
and autoclaving facilities.  Further, the Company  uses (again at no 
additional cost) expensive and specialized equipment located in the 
centralized instrument lab.  Finally, the Company has available the services 
of the University Biotechnology Core Laboratories including the Recombinant 
Protein Expression Core, the DNA Synthesis Core, the Flow Cytometry Core, the 
Protein Chemistry Core, and the Electron Microscopy Core. 

     The Company is developing a small scale facility in its BDI lab suite to 
produce preclinical quantities of its HOF Probe as well as IxC-162.  
Commercial 
scale production, if any, will be subcontracted to third party contract 
manufacturers.  See "Business - Business Strategy."  The facilities license 
agreement for the Company's laboratory and administrative offices at the BDI 
has  one year remaining of its three-year term expiring July 31, 1998 at which 
time the Company will likely be required to relocate.  Annual payments 
(including utilities) are approximately $43,200, a portion of which is 
deferred under the agreement with the University.
     
     Contract Suppliers and Manufacturers.  It is the Company's present 
intention to enter into agreements with contract testing and manufacturing 
entities to test and manufacture commercial quantities of the Company's 
planned products in order to avoid the expenditure of significant funds to 
hire and train personnel and comply with the extensive regulations, including 
"good manufacturing practice" ("GMP") requirements applicable to such a 
facility.

Legal Proceedings

     The Company is not a party to any legal proceedings and is not aware of 
any threatened litigation or regulatory action that could have a material 
adverse effect on the Company's business, financial condition, or results of 
operations.

Employees

     The Company has five full time employees and six part time employees, 
including Dr. Peck, who is an exclusive consultant, Mr. Peck, President and 
Chief Financial Officer, Mr. Tedesco, Vice President - Operations and 
Regulatory Affairs, and Ms. Ramsey, Controller.  The Company is not subject to 
any  collective bargaining agreements and believes that its relationship with 
its employees is good.

Scientific Advisory Board

     None of the members of the Scientific Advisory Board (the "Scientific 
Advisors") are employees of the Company.  Members devote only a small portion 
of their time to the Company and have commitments to other institutions which 
may conflict or compete with their obligations to the Company.  Scientific 
Advisors review and evaluate the Company's research programs, advise the 
Company with respect to technical matters in fields in which the Company is 
involved, consult on aspects of product planning and feasibility studies, 
assist in establishing research priorities, provide guidance on clinical 
evaluation programs, alert the Company to potential collaborators, advise the 
Company on new developments, and recommend personnel to the Company.  

     The Scientific Advisory Board meets periodically as a group.  In 
addition, certain members may meet in smaller groups or individually with 
Company scientists.  Ixion has confidentiality  agreements with each 
Scientific Advisor providing that all confidential information shall be the 
exclusive property of the Company.   Scientific Advisors receive no cash 
compensation, but are reimbursed expenses, and, pursuant to the 1994 Board 
Retainer Plan, 5,000 restricted shares of the Company's Common Stock upon 
joining, and 1,000 restricted shares annually thereafter.  They also receive 
stock options for 2,500 shares annually after their initial year.

     The current members of the Scientific Advisory Board, in chronological 
order of their appointment, are the following:

     Hans Wigzell, M.D., D.Sc.,      Dr. Wigzell is presently the Rector of 
                                     Stockholm's famed Karolinska Institute.

     All directors hold office until the next annual meeting of stockholders 
and until their successors are duly elected and qualified.  Officers are 
elected annually to serve, subject to the discretion of the Board of 
Directors, until their successors are elected or appointed.  The Company's 
Bylaws authorize the Board of Directors from time to time to determine the 
number of its members.  The Board currently consists of four members whose 
terms expire in 1998.   Successors to those directors whose terms have expired 
are required to be elected by stockholder vote; vacancies in unexpired terms 
and any additional positions created by board action are filed by action of 
the existing Board of Directors.

     The Executive Committee, consisting of Messrs. Peck and Gaines, is 
responsible for all matters which arise between meetings of the Board to the 
extent permitted by Delaware law.  The Audit and Benefits Committee, composed 
of Messrs. Peck and Mihalik and Dr. Margulies, recommends to the Board of 
Directors the appointment of the Company's independent auditors, reviews the 
compensation of such auditors, and reviews with them the plans for and results 
and scope of their auditing engagement.  It also determines the salaries and 
incentive compensation of the officers, key employees, and key consultants of 
the Company and administers the Company's 1994 Stock Option Plan and 1994 
Board Retainer Plan.  A majority of its members must be outside directors.  

     The following table summarizes the compensation of those persons who 
were, at December 31, 1996, the Company's Chairman and Chief Executive 
Officer, its President, and its Senior Vice President and Chief Scientist for

Annual Bonus Plan

     In August, 1994, the Board of Directors adopted an annual incentive 
compensation plan (the "Annual Bonus Plan"), administered by the Audit and 
Benefits Committee, pursuant to which officers, employees, and key consultants 
may be awarded cash bonuses (if the Company has sufficient cash to pay such 
bonuses prudently) or deferred bonuses, based on the financial performance of 
the Company.   For 1997, the Audit and Benefits Committee determined that 
awards could range up to 50% of a participant's base salary or consulting fee.
Awards under the Annual Bonus Plan may be made during the first quarter of 
each year at the discretion of the Committee, based on achievement of goals 
set by the Committee.  For each participant, the award ranges from the maximum 
award if the Company achieves its approved goals, to no award if the Company 
achieves less than 70% of its approved goals.  No awards were made relating to 
1996.  

Deferred Compensation Plan

     In January, 1994, the Board of Directors adopted a Deferred Compensation 
Plan for officers, key employees, and consultants of the Company, permitting 
such persons to defer the receipt of all or a portion of their  compensation.  
Under the Deferred Compensation Plan, an unfunded deferred compensation 
account is established for each participant.  The only obligation of the 
Company regarding such account is to make the payments when they become 
payable.  Any amount credited to such account is solely for record-keeping, 
and is not considered to be held in trust or in escrow or in any way vested in 
the participant.  Payments under the Deferred Compensation Plan are to be made 
only upon termination of employment (which may be by death, disability, 
retirement, or otherwise) and may be in a lump sum or as an annuity.  In the 
case of certain senior participants, if termination is by death or dismissal 
without cause, at the election of the participant, the balance in his account 
may be converted into Common Stock of the Company at a price per share not 
greater than the lowest price per share (adjusted for stock splits, stock 
dividends, the issuance of convertible securities, warrants, or options, or 
other dilution) at which shares of the Company's Common Stock have been issued 
(or agreed to be issued) at any time in the 365 days preceding the date of 
termination..  A termination is deemed without cause for substantially the 
same occurrences described under "Employment Agreements," below.  Amounts in 
the account bear interest, compounded annually, at a rate established by the 
Board of Directors, currently 8.0%. 

     At December 31, 1996, balances in the deferred accounts for the Company's 
executive officers and key consultant were as follows:

                      Chairman, Scientific Advisory Board         $ 35,141
__________________________________                              
  (1) Includes accrued interest.

Employment Agreements

     The Company has entered into written agreements (the "Employment 
Agreements") with two of its executive officers, Messrs. Gaines and D. Peck, 
which currently provide for annual base compensation of $95,000 and $60,000, 
respectively.  Base compensation levels are to be reviewed at least annually.  
Upon a determination by the Board that the Company has obtained adequate 
financing, base compensation may be increased to not less than the average 
cash base compensation reported by an appropriate salary survey (as determined 
by the Board) for executive officers at biotechnology companies of equivalent 
size and status.  The effective date of the Employment Agreements is August 
31, 1994, and the initial term of each expires December 31, 1997, renewable 
automatically for one year terms unless either party gives written notice of 
termination at least 92 days before the end of the then current term.  Annual 
bonus compensation, if any, shall be determined by the Board of Directors.

     The Employment Agreements provide that the Company has the right to 
terminate the executive at any time upon 60 days' notice.  A termination for 
cause (as defined in the Employment Agreements) is effective without further 
benefits, upon a finding by the Board of Directors.  Termination without cause 
(as defined in the Employment Agreements), or termination by the executive for 
"Good Reason" (as defined in the Employment Agreements) requires the Company 
to pay severance benefits equal to the aggregate base salary at the then 
current rate payable through the end of the then current term, but not less 
than two times the executive's base compensation.  In addition, the employee 
is eligible for annual bonus compensation calculated in accordance with the 
Annual Bonus Plan.  Finally, all restricted stock is immediately vested, all 
outstanding stock options are immediately vested and accelerated, and the 
executives have the right to purchase Common Stock of the Company pursuant to 
the terms of the Deferred Compensation Plan.  Termination is deemed without 
cause or for "Good Reason" if (i) there is a reduction in the executive's 
annual aggregate compensation or benefits, (ii) there is a diminution in the 
executive's position, powers, authority, duties, or responsibilities, or (iii) 
there is a material breach of the Employment Agreement by the Company.

     The Employment Agreements contain covenants that an executive must 
refrain from engaging in any business competitive with the Company during the 
period of his employment and for six months after termination or resignation 
and must not use, disclose or make accessible to any third party any 
proprietary information of the Company during the period of his employment, or 
thereafter.  All inventions relating to biotechnology generally conceived 
while rendering services to the Company must be assigned to the Company.

Consulting Agreement with Dr. Peck

     The Company has an exclusive consulting agreement expiring on December 
31, 1999, with Dr. Ammon B. Peck for consulting services relating to the 
Company's business and technology.  The fee is $50,000 per year.   Dr. Peck is 
obligated to devote 48 days of service per year to the Company, including 
travel time, and has agreed not to engage in competitive activities with Ixion 
during the term of the agreement, or for two years thereafter.  Generally, 
under the terms of Dr. Peck's employment by the University of Florida, the 
latter has a right of first refusal to any intellectual property and must 
approve  waivers by Dr. Peck of  the University's intellectual property rights 
in any consulting agreement.   Dr. Peck has agreed to assign to the Company 
any inventions or intellectual property rights developed by him while 
performing services under the consulting agreement in  any inventions or 
intellectual property rights waived by the University.  See "Government 
Regulation - Florida Conflicts of Interest."  The consulting agreement may be 
canceled by either party on 30 days' written notice.  The Company has a life 
insurance policy on the life of Dr. Peck in the amount of $500,000 payable to 
the Company.

Consulting Agreement with Brandywine Consultants, Inc.

     In December of 1996, Company entered into a consulting agreement, 
terminable on 90 days' notice by either party, with Brandywine Consultants, 
Inc. (the "Brandywine Consulting Agreement"), of which John L. Tedesco is 
President.  Under the Brandywine Consulting Agreement, Mr. Tedesco was elected 
to the office of the Company's Vice President - Operations and Regulatory 
Affairs, and he and other Brandywine consultants will provide consulting 
services in connection with the strategic planning and execution of the 
Company's drug and device development efforts, as well as services in the area 
of corporate development and financing.  Brandywine must devote not less than 
80 hours per month to the Company's affairs, for which it is paid $5,000 
monthly.  In addition, upon the achievement of certain milestones, Brandywine 
will be issued warrants for up to 20,000 shares of Ixion Common Stock, 
expiring five years from the date of issue, and exercisable at a price of 
$5.00 per share.  Warrants for 3,000 shares, expiring in February 2002 were 
issued on June 23, 1997 upon the approval of the Product Development Plan 
prepared by Brandywine.  Finally, the Company will pay Brandywine a fee on any 
capital raised through investors introduced by a Brandywine consultant.

1994 Stock Option Plan

     In August 1994, the Board of Directors adopted and the shareholders 
approved the 1994 Stock Option Plan (the "Plan").  The Plan was amended in 
June 1997.  The purpose of the Plan is to provide incentive to officers, 
directors, consultants, members of the Scientific Advisory Board, and key 
employees who are, or will be given responsibility for the management or 
administration of the Company's business and the growth of the Company, and to 
provide those personnel with an opportunity to participate in the growth, 
development, and financial success of the Company.

     The Plan reserves an aggregate of 250,000 shares (approximately 6.0% of 
the 4.0 million authorized shares)  of the Company's authorized but unissued 
Common Stock for grants of options to employees and an  additional 75,000 
shares for grants of options to members of the Board of Directors and members 
of the Scientific Advisory Board under the Board Retainer Plan.  At June 30, 
1997, options to purchase 43,900 shares were outstanding, and 281,100 shares 
remained reserved for grants of options under the Plan.

     The Plan permits the grant of both "incentive stock options" within the 
meaning of Section 422 of the Internal Revenue Code (the "Code") and 
nonqualified stock options.  The Committee, in its discretion,  may grant 
options to the Company's employees, consultants,  non-employee directors, and 
members of the Scientific Advisory Board; provided, however, that only 
employees may be granted incentive stock options.  The Committee must be 
composed of at least two outside directors (if there are two outside 
Directors, otherwise such number of outside directors as are available for 
service) and has complete discretion to select the eligible individuals who 
are to receive option grants.  Outside directors who are members of the 
Committee may not be awarded discretionary grants, but are awarded options for 
2,000 shares upon election to the Committee and options for 2,500 shares, all  
exercisable at the then fair market value, annually thereafter.

     Generally, options  become exercisable as to 20% of the shares subject to 
option after the optionee's first full year of continuous service with the 
Company and as to 1/12 of 20% of the shares at the end of each additional full 
month of continuous service thereafter.  Options granted to members of the 
Scientific Advisory Board generally vest at the rate of 25% at the end of each 
three-month period following the grant.

     No incentive stock option may be exercised more than ten years after its 
grant date, or in the case of nonqualified stock options, ten years and one 
day after the date of its grant.  No option is transferable by the optionee 
other than by will or the laws of descent and distribution, and each option is 
exercisable during the lifetime of the optionee only by the optionee, his or 
her guardian, or legal representative.  Subject to certain exceptions,  vested 
incentive stock options expire one year after the optionee's death or 
disability.  Vested nonqualified options expire one year after termination of 
employment for any reason including death.

     The exercise price of incentive stock options may not be less than the 
fair market value of the shares on the date of grant (or 110% of the fair 
market value for incentive stock options granted to holders of 10% or more of 
the stock of the Company or any subsidiary of the Company).   The price may be 
paid in cash, by promissory note, or previously owned shares of the Company. 
 
1994 Board Retainer Plan

     The Company does not  pay cash compensation to outside members of the 
Board of Directors or to members of the Scientific Advisory Board but does 
reimburse expenses incurred in connection with meetings.  Accordingly, the 
Board of Directors adopted the 1994 Board Retainer Plan (amended June 1997) to 
grant shares of Common Stock to such members.  Members of both boards are also 
eligible for grants under the 1994 Stock Option Plan.

     Unvested shares granted are subject to reacquisition by the Company at no 
cost if the grantee ceases to be a director.  With respect to directors, the 
reacquisition option will typically lapse as to 20% of the shares granted 
after the grantee's first full year of continuous service with the Company and 
as to 1/12 of 20% of the granted shares at the end of each additional full 
month of continuous service thereafter.   Scientific Advisors' shares are not 
subject to reacquisition by the Company after a year.

     New outside members of the Board or the Scientific Advisory Board  
receive 5,000 shares upon joining, and each will receive 1,000 shares annually 
thereafter during the pendency of the Board Retainer Plan.  The Audit and 
Benefits Committee of the Board may change the amount granted each eligible 
person at any time in its complete discretion.  75,000 shares were reserved by 
the Board for the Board Retainer Plan, of which 57,000 shares have been 
issued.



                             CERTAIN TRANSACTIONS

     The following is a summary of certain transactions among the Company and 
related persons.

     Commencing with the founding of the Company, Messrs. Gaines and D. Peck 
made loans to the Company pursuant to the terms of a convertible promissory 
note (the "Subordinated Notes").  The amount outstanding varied from month to 
month.   On June 30, 1996, $16,159.04 (the entire outstanding balance 
including accrued interest) of the Subordinated Notes were converted into 
21,544 shares of Common Stock (17,560 shares to Mr. Gaines and 3,984 shares to 
Mr. D. Peck).  The Subordinated notes were converted pursuant to their terms 
at a price per share not greater than the lowest price per share (adjusted for 
stock splits, stock dividends, or other dilution) at which shares of Ixion's 
Common Stock had been issued during the 12 month period immediately prior to 
the notice of election to convert, in this case  at a price of $.75 per share.
Prior to their conversion, the loans bore interest at 8.0%, compounded monthly 
by additions to principal.  No cash interest was ever paid on the Subordinated 
Notes.

     On August 31, 1994, Messrs. Gaines and D. Peck each converted $9,000 of 
principal amount of Subordinated Notes into an aggregate of 900,000 shares of 
the Company's Common Stock, at a price of $0.02 per share.  That price was 
determined by the Board of Directors to be the fair market value of such stock 
on such date.

     On August 31, 1994, the Board of Directors accepted Dr. Ammon B. Peck's 
offer to assign to the Company all his interest in oxalate technology (subject 
to prior rights of the University of Florida under the University's patent 
policy) and to agree to execute an exclusive consulting agreement  with the 
Company in exchange for  an aggregate of 650,000 shares of Common Stock at a 
price of $0.02 per share.  The Board of Directors valued the assignment of 
such rights at not less than $13,000, and determined that amount to be the 
fair market value of the shares on such date.  This transaction was 
consummated on October 17, 1994.

     As of October 10, 1994, members of the immediate families of the founders 
of the Company, including a partnership in which Mr. Gaines has an undivided 
25% interest,  purchased an aggregate of 140,000 shares of the Company's 
Common Stock pursuant to an Agreement to Purchase Shares dated as of such 
date, for a price of $0.10 per share, or $14,000 in the aggregate.

     As of January 1, 1996, the Company purchased used laboratory equipment 
with a replacement value in excess of $60,000 from Carl Therapeutic, Inc. 
(controlled by a vice president of the Company), pursuant to a chattel 
mortgage agreement in the amount of $32,309.  None of this equipment had been 
acquired by Carl Therapeutic within the previous two years.  The agreement 
calls for monthly payments of $897.47 commencing August 1, 1996.  There is no 
interest on the outstanding balance.  The loan is secured by a security 
interest in the laboratory equipment. 

     On April 16, 1996, the Chairman and Chief Executive Officer and the 
President of the Company each entered into an agreement to extend the Company 
up to $25,000 in the form of a bridge loan.  Under these agreements, the 
Company borrowed a total of $32,099.56, all of which was repaid in cash by the 
Company on June 14, 1996.  The loans bore cash interest at the rate 8%, paid 
monthly and upon repayment of the principal.  In addition, the Chairman, on 
June 21, 1996, agreed to increase his loan commitment to an amount up to 
$150,000, if necessary, to enable the Company to continue operations for the 
next year.

     Because of their managerial positions and stock holdings in the Company, 
and their activities related to the organization of the Company, Messrs. 
Gaines and Peck, and Dr. Peck may be deemed to be "promoters" as that term is 
used under the Securities Act.

                          DESCRIPTION OF SECURITIES

Units

Each Unit consists of one share of Common Stock and .25 Charitable 
Benefit Warrant to purchase an additional share of Common Stock.  The Common 
Stock will be immediately separated from the Charitable Benefit Warrants, and 
will be immediately transferable.  

Common Stock 

     As of the date of this Prospectus, the authorized capital stock of the 
Company consists of 4,000,000 shares of Common Stock, $0.01 par value.  As of 
July 1, 1997, there were 2,464,544 shares of Common Stock outstanding, held of 
record by approximately 60 shareholders.

     The holders of Common Stock are entitled to one vote per share on all 
matters to be voted upon by the shareholders.  Holders of Common Stock are 
entitled to receive ratably such dividends, if any, as may be declared from 
time to time by the Board of Directors out of funds legally available 
therefor.  See "Dividend Policy."  In the event of liquidation,  dissolution, 
or winding up of the Company, the holders of Common Stock are entitled to 
share ratably in all assets remaining after payment of liabilities.  The 
Common Stock has no preemptive or conversion rights or other subscription 
rights.  There are no redemption or sinking fund provisions applicable to the 
Common Stock.  All outstanding shares of Common Stock are fully paid and 
nonassessable, and the shares of Common Stock offered hereby will also be 
fully paid and nonassessable.

Charitable Benefit Warrants Included in the Units

     The Charitable Benefit Warrant has been designed to permit purchasers of 
Units in the Offering to make tax deductible contributions of the value of the 
Charitable Benefit Warrant to an approved qualified charitable organization as 
a new modality for channeling funds to medical research.  An approved 
qualified charitable organization means a charitable organization, 
institution, foundation, or research institute described in Section  501(c)(3) 
of the Internal Revenue Code (the "Code"), which is excluded from the 
definition of a private foundation as referred to in Section 509(a) of the 
Code, which is eligible to receive tax-deductible contributions under Section 
170 of the Code, and which has been approved by the Company as described 
below.

     Approved qualified charitable organizations at the date of this agreement 
include the following:

     Juvenile Diabetes Foundation
     American Kidney Foundation
     Vulvar Pain Foundation
     National Vulvodynia Foundation
     Crohn's and Colitis Foundation of America
     Cystic Fibrosis Foundation
     Oxalosis and Hyperoxaluria Foundation
     Mycological Society of America
     Intestinal Disease Foundation
     Cystic Fibrosis Alliance
     National Kidney Foundation
     National Institute of Diabetes and Digestive and Kidney Diseases
     North American Mycological Society
     University of Florida Research Foundation
     Florida Cystic Fibrosis, Inc.

     The Charitable Benefit Warrant included in the Units will be issued 
pursuant to a Warrant Agreement among the Company and SunTrust Bank, Atlanta, 
as warrant agent (the "Warrant Agent"), and will be in registered form. 
Charitable Benefit Warrants may only be transferred to an approved qualified 
charitable organization; provided, however, that transfer to a testamentary 
trust, legatee, or heir by will or by descent upon the death of a Registered 
Holder, will be permitted upon proper proof as decided by the Company.  A 
registered holder may transfer Charitable Benefit Warrants to an approved 
qualified charitable organization at any time from the time of issuance and 
prior to the close of business on September ___, 2007, the Warrant Expiration 
Date.

     Qualified charitable organizations may be added to the approved list by 
the Company, in its absolute discretion, from time to time until the Warrant 
Expiration Date.  In order to be added to the approved list, a charitable 
organization must be tax exempt, and it must be eligible to receive tax 
deductible contributions in accordance with Section 170 of the Code.  
Charitable organizations may be added at the election of the Company, or they 
may be nominated by a Registered Holder.  Registered Holders wishing to 
nominate a charitable organization must send their nomination in writing to 
the Company, together with proof of such charitable organization's status as 
an organization described in Section 501(c)(3) of the Code which is excluded 
from the definition of a private foundation as referred to in Section 509(a) 
of the Code and which is eligible to receive tax deductible contributions in 
accordance with Section 170 of the Code.  Charitable organizations that fall 
into the excluded categories are generally those that either have broad public 
support or actively function in a supporting relationship to such 
organizations.

     In order to be tax-exempt, an organization must be organized and operated 
exclusively for one or more of the purposes set forth in Section 501(c)(3), 
and none of the earnings of the organization may inure to any private 
shareholder or individual.  In addition, the organization may not attempt to 
influence legislation as a substantial part of its activities, nor may it 
participate at all in campaign activities for or against political candidates.
The Company will favor charitable organizations which dedicate a material 
portion of their assets or revenue to research activities connected with the 
cure and treatment of diabetes and oxalate-related diseases.

     Each of the Warrants will entitle the holder to purchase one share of 
Common Stock at a price of $20.00 per share.  An approved qualified charitable 
organization may exercise at any time from the date of issuance and prior to 
the close of business on September ____, 2007.  A holder who is not an 
approved qualified charitable organization may not exercise during the first 
nine years.  Such holder may only exercise during the one-year period 
commencing September __, 2006, and ending at the close of business September 
__, 2007.

     The exercise price of the Charitable Benefit Warrants, and the number and 
kind of shares of Common Stock or other securities and property issuable upon 
exercise of the Warrants are subject to adjustment in certain circumstances, 
including a stock dividend or a subdivision or combination of the Common 
Stock.  Additionally, an adjustment will be made upon a reclassification or in 
case of a consolidation or merger of the Company with or into another company 
or the sale of all or substantially all of the assets of the Company, in order 
to enable approved qualified charitable organization holders of Charitable 
Benefit Warrants to purchase the kind and number of shares of stock or other 
securities or property (including cash) receivable in such event by a holder 
of the number of shares of Common Stock that might otherwise have been 
purchased upon exercise of the Charitable Benefit Warrant.  No adjustment for 
previously paid cash dividends, if any, will be made upon exercise of the 
Charitable Benefit Warrant.

     Charitable Benefit Warrants do not confer upon the holder any voting or 
any other rights of a stockholder of the Company.  Upon notice to the Warrant 
holders, the Company has the right to reduce the exercise price or extend the 
expiration date of the Charitable Benefit Warrants.

     The Charitable Benefit Warrants may be exercised only upon surrender of 
the Charitable Benefit Warrant certificate on or prior to the expiration date 
of such Warrant at the offices of the Warrant Agent, with the form of 
"Subscription Form" on the reverse side of the Charitable Benefit Warrant 
certificate completed and executed as indicated, accompanied by payment of the 
full exercise price (by certified check payable to the order of the Warrant 
Agent) for the number of Charitable Benefit Warrants being exercised.


Unsecured Convertible Notes

     In 1996 the Company issued $787,270 total principal amount, composed of 
$215,600 in 10% Unsecured Convertible Notes (the "10% Notes") and $571,670 in 
Variable Conversion Rate Unsecured Convertible Notes (the "Variable Notes") 
due 2001 (in the aggregate hereafter called the "Notes"), which were issued 
under a Note Purchase Agreement (the "Note Purchase Agreement"), dated as of 
September 13, 1996, between the Company and the initial purchasers of the 
Notes.   The 10% Notes accrue interest at the stated rate until maturity, or 
conversion, and pay interest quarterly.  The 10% Notes are convertible into 
shares of the Company's Common Stock at any time prior to maturity at a 
conversion price of $4.20 per share.  The Variable Notes are non-interest 
bearing and are convertible into shares of the Company's Common Stock, at any 
time prior to maturity, at variable conversion prices ranging from $4.20 to 
$2.10.  The variable conversion prices are based on the length of time the 
investor holds the Variable Notes prior to conversion, as shown in the table 
below:

Conversion Date                                               Conversion Price

End of         Year 1     Year 2     Year 3     Year 4     Year 5

November        $4.10     $3.70      $3.30      $2.90      $2.50
February        $4.00     $3.60      $3.20      $2.80      $2.40
May             $3.90     $3.50      $3.10      $2.70      $2.30
August          $3.80     $3.40      $3.00      $2.60      $2.10


Outstanding Common Stock Purchase Warrants

     As of July 1, 1997, there were outstanding warrants to purchase 20,630 
shares of Common Stock.  Warrants for 17,630 shares entitle the registered 
holder to purchase Common Stock at a price of $2.00 per share through August 
31, 2000.  Warrants for 3,000 shares entitle the registered holder to purchase 
Common Stock at a price of $5.00 per share through February 2002.  The 
exercise price of the warrants and the number  of shares of Common Stock to be 
obtained upon exercise of the warrants are subject to adjustment in certain 
circumstances, including a stock dividend to holders of Common Stock, a 
subdivision or combination of outstanding shares of Common Stock, or the 
issuance of capital stock in a reclassification or reorganization of Common 
Stock.  The exercise price of the warrants is subject to adjustment in the 
event that the Company (i) issues, sells, or otherwise distributes Common 
Stock at a price which is less than the then current market price of the 
Common Stock, (ii) issues options (other than options issued under the 1994 
Stock Option Plan or the 1994 Board Retainer Plan) whose exercise price is 
less than the then current market price of the Common Stock, (iii) issues 
convertible securities whose conversion price is less than the then current 
market price of the Common Stock, or (iv) pays a dividend of cash or other 
property in any one year greater than 10% of the then current market price of 
the Common Stock.  The Company must give advance notice to warrant holders of 
any of the above events as well as any merger, sale, transfer, dissolution, or 
winding up.

     The warrants do not confer upon the holder any voting or other rights of 
a shareholder of the Company.  Upon notice to the holders of the warrants, the 
Company has the right to reduce the exercise price or extend the expiration 
date of the warrants.  See "Shares Eligible for Future Sale - Registration 
Rights" for a description of the registration rights of holders of certain of 
the warrants.

Limitation of Liability

     As permitted by Delaware law, the Certificate of Incorporation provides 
that no director of the Company will be liable for monetary damages for breach 
of fiduciary duty as a director, except (i) for any breach of the director's 
duty of loyalty to the Company or its stockholders, (ii) for acts or omissions 
not in good faith or involving intentional misconduct or a knowing violation 
of law, (iii) for approval of certain unlawful dividends or stock purchases or 
redemptions, and (iv) for any transaction from which the director derived an 
improper personal benefit.  In appropriate circumstances, equitable remedies 
such as an injunction or other forms of non-monetary relief would remain 
available under Delaware law.

     The Company intends to purchase and maintain directors' and officers' 
insurance as soon as the Board of Directors determines practicable, in amounts 
which they consider appropriate, insuring the directors against any liability 
arising out of the director's status as a director of the Company regardless 
of whether the Company has the power to indemnify the director against such 
liability under applicable law.

     The Company has been advised that it is the opinion of the Commission 
that insofar as the foregoing provisions may be invoked to disclaim liability 
for damages arising under the Securities Act, or to claim indemnification for 
such liability, such provisions are against public policy as expressed in the 
Securities Act and are, therefore, unenforceable.

                 CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES

     The following is a summary of certain federal income tax considerations 
relevant to the acquisition, holding, and disposition of Units, Common Stock, 
and Charitable Benefit Warrants pursuant to this Offering.  This discussion is 
not a complete analysis of all potential tax considerations to prospective 
purchasers.  The discussion is limited solely to U.S. federal income tax 
matters and is based upon the Internal Revenue Code of 1986, as amended (the 
"Code"), Treasury regulations, administrative rulings, and pronouncements of 
the Internal Revenue Service ("IRS"), and judicial decisions, all as of the 
date hereof and all of which are subject to change at any time, possibly with 
retroactive effect.

     This discussion is limited to those initial purchasers of Units who would 
hold the Common Stock and Charitable Benefit Warrants as "capital assets" for 
U.S. federal income tax purposes.  This discussion does not address U.S. 
federal income tax consequences that may be applicable to particular 
categories of Unit holders, including insurance companies, tax-exempt persons, 
financial institutions, dealers in securities, persons with significant 
holdings of Company stock, and non-United States persons, including foreign 
corporations, foreign partnerships, and nonresident alien individuals.  This 
discussion does not address any tax considerations under the laws of any 
state, locality, or jurisdiction, or foreign country.

     The Company will not seek, a ruling from the IRS as to any of the matters 
covered by this discussion, and there can be no assurance that the IRS will 
not successfully challenge the conclusions reached in this discussion.  
BECAUSE THE U.S. FEDERAL INCOME TAX CONSEQUENCES DISCUSSED BELOW DEPEND UPON 
EACH HOLDER'S PARTICULAR TAX STATUS, PROSPECTIVE INVESTORS SHOULD CONSULT 
THEIR OWN TAX ADVISORS REGARDING THE APPLICATION OF THE TAX CONSIDERATIONS 
DISCUSSED BELOW TO THEIR PARTICULAR SITUATIONS, AS WELL AS THE APPLICATION OF 
ANY STATE, LOCAL, FOREIGN, OR OTHER TAX LAWS.

The Units

     Because the original purchasers of Common Stock also will acquire 
Charitable Benefit Warrants, each share of Common Stock likely will be treated 
for federal income tax purposes as having been issued as part of an 
"investment unit" consisting of the Common Stock and associated Charitable 
Benefit Warrants.  The purchase price of an investment unit is allocated 
between its component parts based on their relative fair market values at the 
time of purchase.  The portion of the purchase price allocable to the Common 
Stock and Charitable Benefit Warrants, respectively, will be the holder's 
initial tax basis in the Common Stock and Charitable Benefit Warrants, 
respectively.

The Common Stock

     Dividends.  The Company does not currently intend to make distributions 
with respect to the Common Stock.  However, any distributions that are made by 
the Company with respect to the Common Stock will be characterized as 
dividends and, therefore, will be includable in the recipient's gross income 
to the extent of the Company's current or accumulated earnings and profits, if 
any, as determined for U.S. federal income tax purposes.  To the extent that a 
distribution on the Common Stock exceeds the holder's allocable share of the 
Company's current or accumulated earnings and profits, such distribution first 
will be treated as a return of capital that will reduce the holder's adjusted 
tax basis in such Common Stock, and the excess will be treated as taxable 
gain.  The availability of current or accumulated earnings and profits, if 
any, in future years will depend on future profits and losses which cannot be 
accurately predicted.  Thus, there can be no assurance that all or any portion 
of a distribution on the Common Stock will be characterized as a dividend for 
U.S. federal income tax purposes.  Corporate stockholders will not be entitled 
to claim the dividends received deduction with respect to distributions that 
are not characterized as dividends.  See the discussion regarding the 
dividends received deduction below.

     Subject to important restrictions, dividends received by a corporate 
holder of Common Stock generally will qualify for the 70 percent dividends 
received deduction provided by Section 243(a)(1) of the Code.  Under certain 
circumstances, a corporate holder may be subject to the alternative minimum 
tax with respect to the amount of its dividends received deduction.  Also, 
under certain circumstances, a corporation that receives an "extraordinary 
dividend," as defined in Section 1059(c) of the Code, is required to reduce 
its stock basis by the nontaxed portion of such dividend.  Corporate holders 
are advised to consult their tax advisors concerning possible limitations on 
the availability of the dividends received deduction, as well as the potential 
application of Section 1059 of the Code with respect to dividends received 
from the Company.  

     Sale or other Taxable Disposition of Common Stock.  Upon a sale or other 
taxable disposition (other than a redemption) of Common Stock, a holder 
generally will recognize gain or loss for federal income tax purposes in an 
amount equal to the difference between (i) the amount of cash plus the fair 
market value of any property received upon such sale or disposition and (ii) 
the holder's adjusted tax basis in the Common Stock being sold.  The holder's 
adjusted tax basis in the Common Stock will be that amount of the purchase 
price of a Unit allocated to the Common Stock as described above.

     Redemption of Common Stock.  The Company has no plans to redeem Common 
Stock.  A redemption of Common Stock generally will be a taxable event to the 
redeemed stockholder.  The amount received in the redemption will be treated 
as a distribution taxable as a dividend to the redeemed stockholder (and may 
constitute an extraordinary dividend under Section 1059) unless the 
redemption:  (a) is treated as a distribution "not essentially equivalent to a 
dividend" with respect to the stockholder; (b) is "substantially 
disproportionate" with respect to the stockholder; (c) "completely terminates" 
the stockholder's equity interest in the Company; or (d) is of stock held by a 
noncorporate stockholder and is in partial liquidation of the Company.  In 
determining whether any of those tests has been met, there generally must be 
taken into account Common Stock actually owned and certain Common Stock 
constructively owned by the stockholder.  If any of those tests is met as to a 
stockholder, the redemption of the Common Stock generally would be treated as 
to that stockholder as an exchange giving rise to capital gain or loss 
(measured by the difference between the amount received and the holder's tax 
basis in the redeemed Common Stock).  Even in such a case, however, payments 
received upon redemption which represent accrued but unpaid dividends may be 
taxed as ordinary income dividends, and the extraordinary dividend rule 
discussed above could apply.  Prospective purchasers should consult their own 
tax advisors as to the application of the foregoing rules.

The Charitable Benefit Warrants

     Exercise of the Charitable Benefit Warrants.    The exercise of a 
Charitable Benefit Warrant will not result in a taxable event to the holder.  
Upon exercise of a Charitable Benefit Warrant, the holder's aggregate basis in 
the Common Stock received upon exercise (the "Warrant Shares") will be the sum 
of (a) its basis in the Charitable Benefit Warrant and (b) the cash paid upon 
exercise of the Charitable Benefit Warrant.  The holding period for capital 
gain and loss purposes for the Warrant Shares will not include the period 
during which the Charitable Benefit Warrant was held by such holder.

     Expiration of the Charitable Benefit Warrants.  Upon the expiration of an 
unexercised Charitable Benefit Warrant, the holder will recognize a loss equal 
to the adjusted tax basis of the Charitable Benefit Warrant in the hands of 
the holder.  Such loss will be a capital loss, provided the Warrant Shares 
would have been a  capital asset in the hands of the Charitable Benefit 
Warrant holder had the Charitable Benefit Warrant been exercised, and will be 
long-term capital loss with respect to Charitable Benefit Warrants held for 
more than one year at the time of the expiration.

     Adjustments Under the Charitable Benefit Warrants.  Pursuant to the terms 
of the Charitable Benefit Warrants, the number of shares that may be purchased 
upon exercise of the Charitable Benefit Warrants is subject to adjustment from 
time to time upon the occurrence of certain events.  Under Section 305 of the 
Code, a change in conversion ratio or any transaction having a similar effect 
on the interest of a Charitable Benefit Warrant holder may be treated as a 
distribution with respect to any holder whose proportionate interest in the 
assets or earnings and profits of the Company is increased by such change or 
transaction.  Thus, under certain future circumstances which may or may not 
occur, such an adjustment pursuant to the terms of the Charitable Benefit 
Warrants may be treated as a taxable distribution to the Charitable Benefit 
Warrant holders to the extent of the Company's current or accumulated earnings 
and profits, without regard to whether such holders receive any cash or other 
property.  If the Charitable Benefit Warrant holders receive such a taxable 
distribution, their bases in the Charitable Benefit Warrants will be increased 
by an amount equal to the taxable distribution.

     The rules with respect to adjustments are complex and Charitable Benefit 
Warrant holders should consult their own tax advisors in the event of an 
adjustment.

     Charitable Contribution of Charitable Benefit Warrants.  Upon charitable 
contribution of a Charitable Benefit Warrant to an approved qualified 
charitable organization, the transferor will be entitled to a deduction in 
respect of a charitable contribution in an amount equal to the fair market 
value of the Charitable Benefit Warrant to such transferor at the time of such 
contribution, subject to the usual requirements for deductions in respect of 
charitable contributions, including, without limitation, certain annual 
limitations on deductions based on adjusted gross income and other 
requirements referred to below.  

     The fair market value of the Charitable Benefit Warrant at the time of 
any such contribution will be based on the value of the Charitable Benefit 
Warrant in the hands of the transferor at that time.  That is, the Charitable 
Benefit Warrant will be valued as a warrant that may be exercised only during 
the one year period commencing September __, 2006 and ending September __, 
2007, notwithstanding that an approved qualified charitable organization may 
exercise the Charitable Benefit Warrant at any time after issuance.  
Individuals and certain other transferors are required to obtain an appraisal 
of the fair market value of property contributed if the deduction claimed for 
the contribution of such property and all similar property exceeds $5,000 in 
any one taxable year (including donations to different donees).    Certain 
other substantiation requirements apply as well.  

     The amount of any deduction in respect of a charitable contribution of 
appreciated property is reduced by, among other things, the amount of gain 
which would not have been long-term capital gain if the property contributed 
had been sold by the taxpayer at its fair market value (determined at the time 
of such contribution).  To avoid that reduction, a holder must hold the 
property for a period of time such that its disposition would result in long-
term capital gain, which currently is any period longer than one year. 

     The substantiation and other requirements for a deduction in respect of 
charitable contribution are, in part, highly technical.  Accordingly, a holder 
of Charitable Benefit Warrants who is planning to contribute Charitable 
Benefit Warrants to an approved qualified charitable organization is urged to 
consult his or her own tax advisor with respect to those requirements.  

Backup Withholding

     Federal income tax backup withholding at a rate of 31% on dividends and 
proceeds from a sale, exchange, or redemption of Common Stock will apply 
unless the holder (i) is a corporation or comes within certain other exempt 
categories (and, when required, demonstrates that fact) or (ii) provides a 
taxpayer identification number, certifies as to no loss of exemption from 
backup withholding and otherwise complies with applicable requirements of the 
backup withholding rules.  The amount of any backup withholding from a payment 
to a holder will be allowed as a credit against the holder's federal income 
tax liability and may entitle such holder to a refund, provided that the 
required information is furnished to the IRS.


SHARES ELIGIBLE FOR FUTURE SALE

     At the completion of this Offering, there will be 2,864,544 shares of 
Common Stock outstanding if all Units are sold.  There will be 43,900  shares 
of Common Stock issuable upon the exercise of outstanding options, 20,630 
issuable upon the exercise of outstanding warrants, and up to 323,557 shares 
of Common Stock issuable upon conversion of the Company's Unsecured 
Convertible Notes.  There is no current market for the Company's securities, 
and it is unlikely there will be one at the conclusion of this Offering.

     Should the Company elect to register its securities in the future, it 
cannot predict whether a market for its securities will develop, or, if one 
develops, the effect, if any, that market sales of restricted shares of Common 
Stock (described below) or the availability of such shares for sale will have 
on the market prices prevailing from time to time.  Nevertheless, the 
possibility that substantial amounts of Common Stock may be sold in the public 
market would likely adversely affect any prevailing market price for the 
Common Stock and could impair the Company's ability to raise capital through 
the sale of its equity securities.

Sales of Restricted Securities

     All 2,464,544 shares of Common Stock outstanding prior to the Offering, 
all outstanding warrants and options, and all Unsecured Convertible Notes, as 
well as the shares of Common Stock issuable upon exercise of such warrants and 
options or conversion of the Unsecured Convertible Notes were or will be 
issued and sold by the Company in private transactions not involving a public 
offering in reliance upon exemptions under the Securities Act.  These 
securities are treated as "restricted securities" and may not be resold except 
in compliance with the registration requirements of the Securities Act or 
pursuant to an exemption therefrom.

Registration Rights

     Pursuant to the Agreement to Purchase Shares dated as of October 10, 
1994, the holders of 140,000 shares of Common Stock ("Contingently 
Registerable Securities") are entitled to certain contingent piggyback 
registration rights, subject to the terms and conditions of the Agreement to 
Purchase Shares.  Under such Agreement, if at any time during the period 
ending October 9, 2004, Ixion registers any shares of Common Stock under the 
Act on certain SEC forms, one or more holders of the Contingently Registerable 
Securities may request that all or a part of their securities be included in 
the registration statement.  The Company is required to bear all registration 
and selling expenses (other than underwriter's fees, discounts, or 
commissions) in connection with the registration of Contingently Registerable 
Securities.  See "Certain Relationships and Related Transactions."

     Pursuant to the Employment Agreements, Messrs. D. Peck and Gaines, 
holders of record of an aggregate of  911,544  shares of the Company's Common 
Stock as of July 31, 1996  (the "Registerable Securities") are entitled to 
certain demand registration rights, subject to the terms and conditions of 
such Employment Agreements.  Subject to certain exceptions, if the Company is 
then a public company, at any time during the contract term (and until the 
third anniversary of termination), either or both of Messrs. D. Peck and 
Gaines may demand that the Company register at least 100,000 shares under the 
Act on an appropriate SEC form.  Each executive is entitled to only one demand 
registration under his Employment Agreement.  Each executive may also request 
inclusion of all or a portion of his Registerable Securities in any 
registration by the Company under the Act.  The Company is required to bear 
all registration and selling expenses (other than underwriter's fees, 
discounts, or commissions) in connection with the registration of Registerable 
Securities.  See "Management - Employment Agreements."

     Holders of 17,630 outstanding warrants have certain piggyback 
registration rights for the Common Stock issuable upon exercise of such 
warrants, subject to the terms and conditions of the warrants.  Pursuant to 
the terms of such warrants, until June 30, 2001, if the Company registers any 
sales of Common Stock under the Securities Act, it must notify the warrant 
holders in order that they may request inclusion in such registrations 
statement.  The expenses of the registration (other than transfer taxes, 
underwriting commissions, and fees of warrant holders' counsel) shall be paid 
by the Company.

     Pursuant to the Note Purchase Agreement relating to the Unsecured 
Convertible Notes, until August 31, 2006, Note holders who convert their 
Unsecured Convertible Notes into shares of Common Stock are also entitled to 
certain contingent piggyback registration rights.  The expenses of the 
registration (other than transfer taxes, underwriting commissions, and fees of 
the converting Note holders' counsel) shall be paid by the Company.
     
                             PLAN OF DISTRIBUTION

     The Company proposes to sell up to 400,000 Units composed of 400,000 
newly issued shares of Common Stock and 100,000 newly issued Charitable 
Benefit Warrants at a price of $10.00 per Unit directly to members of the 
public residing in selected states.  Announcements of this Offering, in the 
form prescribed by Rule 134 of the Securities Act, will be communicated to 
selected persons.  There is no required minimum number of Units to be sold, 
and all funds received will go immediately to the Company.  If only a few 
Units are sold, the result could be that all the proceeds will be used to pay 
the expenses of the Offering.  The Offering will begin on the date of this 
Prospectus and continue for up to twelve months (unless extended) or until all 
of the Units offered are sold or such earlier date as the Company may close or 
terminate the Offering.  All Units will be sold at the public offering price 
of $10.00 per share and a minimum purchase of  100 Units ($1,000.00) is 
required.  Since there is no minimum number of Units to be sold, there is no 
escrow account for the deposit of subscribers' funds and no arrangements to 
return the funds if all of the Units offered are not sold. 

     The Company plans to offer and sell the Units directly to investors and 
has not retained any underwriters, brokers, dealers, or placement agents in 
connection with the Offering.  However, the Company reserves the right to use 
brokers, dealers, or placement agents and could pay commissions equal to as 
much as 10 percent of the gross proceeds although the Company does not 
currently intend to pay more than $200,000 in aggregate commissions.   The 
Company will effect offers and sales of Units through printed copies of this 
Prospectus delivered by mail and electronically, by contacting prospective 
investors by publicizing the Offering through a posting on the Company's World 
Wide Web site (which was first established in July of 1996), by  publicizing 
the Offering through newspaper advertisements, and by contacting additional 
potential investors by direct e-mail and regular mail solicitation.  Any voice 
or other communications will be conducted in certain states through the 
Company's executive officers, and in other states, where required, through a 
designated sales agent, licensed in those states.  Under Rule 3a4-1 of the 
Exchange Act, none of these employees of the Company will be deemed a 
"broker," as defined in the Exchange Act, solely by reason of participation in 
this Offering, because (1) none is subject to any of the statutory 
disqualifications in Section 3(a)(39) of the Exchange Act, (2) in connection 
with the sale of the Units offered, none will receive, directly or indirectly, 
any commissions or other remuneration based either directly or indirectly on 
transactions in securities, (3) none is an associated person (partner, 
officer, director, or employee) of a broker or dealer, and (4) each meets all 
of the following conditions: (a) primarily performs substantial duties for the 
issuer otherwise than in connection with transactions in securities; (b) was 
not a broker or dealer, or an associated person of a broker or dealer, within 
the preceding 12 months; and (c) will not participate in selling an offering 
of securities for any issuer more than once every 12 months. 

     To subscribe for Units, each prospective investor must complete, date, 
execute and deliver to the Company a Unit Purchase Agreement and have paid the 
purchase price of the Units subscribed for by check payable to Ixion 
Biotechnology, Inc.  A copy of the Unit Purchase Agreement is included with 
this Prospectus.

     The Company reserves the right to reject any Unit Purchase Agreement in 
its entirety or to allocate Units among prospective investors.  If any Unit  
Purchase Agreement is rejected, funds received by the Company for such 
subscription will be returned to the subscriber without interest or deduction.

     Within five days of its receipt of a Unit  Purchase Agreement accompanied 
by a check for the purchase price, the Company will send by first class mail a 
written confirmation to notify the subscriber of the extent, if any, to which 
such subscription has been accepted by the Company.  Not more than thirty days 
following the mailing of its written confirmation, a subscriber's Common Stock 
and Charitable Benefit Warrant certificates will be mailed by first class 
mail.  The Company shall not use the proceeds paid by any investor until the 
Common Stock and Charitable Benefit Warrant certificates evidencing such 
investment have been mailed.

     There is no public market for the Common Stock, and it is unlikely that 
any such market will develop after the Offering.  The Company does not 
currently meet the requirements for listing on an organized stock exchange or 
quotation of over-the-counter market maker trades on the NASDAQ market. After 
completion of the Offering, the Company may apply for a listing on a United 
States regional exchange, if the Company meets certain numerical listing 
requirements.  However, there can be no assurance that the Company will be 
listed or that a market will develop or be sustained.  If it does not, the 
Company has been advised that a registered securities broker-dealer may 
provide an order matching service for persons wishing to buy or sell shares, 
upon completion of the Offering.  However, there is currently no agreement 
between the Company and such a registered securities broker-dealer.  The 
Company may in the future also seek to provide a passive, bulletin board 
system on the Internet providing information to buyers and sellers of the 
Company's Common Stock to facilitate trading.  The System would not affect 
transactions and would be obliged to meet the requirements of the Commission.  
The Company has not constructed such a system at the date of this Prospectus.  
In the absence of a public trading market, purchasers may be unable to resell 
the Common Stock for an extended period of time, if at all.  

Determination of Offering Price

     The Company has arbitrarily determined the offering price of the Units.  
Among the factors considered in determining such price were offering prices of 
recent biotechnology initial public offerings, the Company's capital 
requirements, the percentage of ownership to be held by investors following 
the Offering, the prospects for the Company's business and the biotechnology 
industry, the assessment of the present early stage of the Company's 
development, the prospects for initiation or growth of the Company's revenues, 
and the current state of the economy in the United States.  The offering price 
does not necessarily bear any relationship to the Company's assets, book 
value, earnings history, or other investment criteria and  should not be 
considered an indication of the actual value of the Company's securities.  

                                LEGAL MATTERS

     Certain legal matters in connection with validity of the Units offered 
hereby will be passed upon for the Company by Bruce Brashear, Esq., 
Gainesville, Florida. Certain tax matters in connection with the investment in 
Charitable Benefit Warrants will be passed on for the Company by Thacher 
Proffitt & Wood, New York, New York.  James R. Shorter, Jr., a partner in
Thacher Proffitt & Wood, is the beneficial owner of approximately 1.2% of the
Company.

The Board of Directors
Ixion Biotechnology, Inc.

We have audited the balance sheet of Ixion Biotechnology, Inc. (A Development 
Stage Company) as of December 31, 1996, and the related statements of 
operations, capital deficiency and cash flows for the years ended December 31, 
1996 and 1995 and for the period March 25, 1993 (date of inception) through 
December 31, 1996.  These financial statements are the responsibility of the 
Company's management.  Our responsibility is to express an opinion on these 
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing 
standards.  Those standards require that we plan and perform the audits 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 Ixion Biotechnology, Inc. at 
December 31, 1996, and the results of its operations and its cash flows for 
the years ended December 31, 1996 and 1995 and for the period March 25, 1993 
(date of inception) through December 31, 1996 in conformity with generally 
accepted accounting principles.

Ixion Biotechnology, Inc.
(A Development Stage Company)

Notes to Financial Statements

Years Ended December 31, 1996 and 1995 and the Period March 25, 1993 (Date of 
Inception)     through December 31, 1996


1.  Significant Accounting Policies:
Organization - Ixion Biotechnology, Inc., a Delaware corporation (the 
"Company"), was incorporated on March 25, 1993 and has been in the 
development stage since its formation.  The Company is in business to 
develop pharmaceutical products and medical devices to detect, diagnose, 
treat or prevent diabetes and oxalate-induced diseases.  The Company has 
not generated significant revenues to date and has experienced operating 
losses since its inception.  The Company expects to incur additional 
operating losses for the next several years as the Company expands its 
research and development and regulatory activities and prepares for the 
manufacturing and marketing of its products.

Basis of Presentation - The Company is in the development stage since it 
is devoting substantially all of its efforts to establishing its business 
and its planned principal operations have not commenced.  Successful 
completion of the Company's development program, and its transition to 
profitable operations, is dependent upon obtaining approval to market its 
products from the United States Food and Drug Administration and 
achieving revenues from the commercial development of its products.

Cash and Cash Equivalents - The Company considers all highly liquid 
instruments with a maturity of three months or less at time of purchase 
to be cash equivalents.

Income Taxes - Deferred income taxes are recognized for the tax 
consequences in future years of differences between the tax bases of 
assets and liabilities and their financial reporting amounts at each year 
end based on enacted tax laws and statutory tax rates applicable to the 
periods in which the differences are expected to affect taxable income.  
Valuation allowances are established when necessary to reduce deferred 
tax assets to the amount expected to be realized.  Income tax expense is 
the tax payable for the period and the change during the period in 
deferred tax assets and liabilities.

Property and Equipment - Property and equipment are stated at cost.  
Gains and losses on disposition are recognized in the year of the 
disposal.  Expenditures for maintenance and repairs are expensed as 
incurred.
Depreciation is computed using the straight-line method over the 
estimated lives of the assets (5 years).

Patents Pending - Patents pending consist of direct costs incurred in 
connection with the applications for patents.  No patents have received 
final approvals at December 31, 1996.  Amortization of these costs over 
the estimated life will begin upon final approvals or expensed 
immediately if rejected.
                                                                        7

1.  Significant Accounting Policies - Continued:

Research and Development - Research and development costs are charged to 
expense as incurred.

Other Assets - Other assets consists of organizational costs and loan 
costs associated with convertible notes.  The organizational costs are 
being amortized on a straight-line basis over five years.  Loan costs are 
being amortized over the term of the notes payable.

Net Loss Per Common Share - Except as noted below, historical net loss 
per share is computed using the weighted average number of common shares 
outstanding for the period.  Common equivalent shares from stock options, 
warrants and convertible notes payable are excluded from the computation 
as their effect is antidilutive.  However, pursuant to an SEC Staff 
Accounting Bulletin, common and common equivalent shares issued during 
the period beginning 12 months prior to the initial filing of the 
proposed public offering, at prices substantially below the assumed 
public offering price, have been included in the calculation as if they 
were outstanding for all periods presented (using the treasury stock 
method and the assumed public offering price).

Reclassifications - For comparability purposes, certain reclassifications 
have been made to the 1995 financial statements to conform with the 1996 
financial statement presentation.

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 reporting period.  Actual results could differ from 
those estimates.

Recently Issued Accounting Standards - The Financial Accounting Standards 
Board recently issued Statement No. 128, Earnings Per Share.  This 
statement is effective for the year ending December 31, 1997 and 
establishes standards for computing and presenting earnings per share.  
Applying the provisions of this pronouncement, the Company would have 
reported Basic Net Loss Per Share and Diluted Net Loss Per Share of 
approximately $(.22) per share.



2.  Property and Equipment:
    Property and equipment consists of the following as of December 31, 1996:

</TABLE>

3.  Notes Payable:
On March 15, 1996, the Company entered into a written agreement to 
purchase certain laboratory equipment for a sales price of $32,309, 
payable in 36 monthly installments of $897, including interest, beginning 
August 1, 1996.  As of December 31, 1996, $28,022 in principal remains 
outstanding under this agreement.

                                                                        8
<PAGE>

In September, 1996, the Company completed the private placement of 
$787,270 in Convertible Unsecured Notes due 2001.  The private placement 
provided investors with the option of either 10% Convertible Unsecured 
Notes ("10% Notes") or Variable Conversion Rate Convertible Unsecured 
Notes ("Variable Notes").  The 10% Notes accrue interest at the stated 
rate until maturity, or conversion, and pay interest quarterly commencing 
on November 30, 1996.  The 10% Notes are convertible into shares of the 
Company's common stock, at any time prior to maturity, at a conversion 
price of $4.20 per share.  The Variable Notes are non-interest bearing 
and are convertible into shares of the Company's common stock, at any 
time prior to maturity, at variable conversion prices ranging from $4.20 
to $2.10.  The variable conversion prices are based on the length of time 
the investor holds the notes prior to conversion.  As of December 31, 
1996, there were $215,600 of 10% Notes and $571,670 of Variable Notes 
outstanding.  Accrued interest on the 10% Notes totaled $1,796 as of 
December 31, 1996.

Future principal maturities of notes payable for each of the five years 
subsequent to December 31, 1996 are as follows:

4.  Income Taxes:

The components of the Company's net deferred tax asset and the tax 
effects of the primary temporary differences giving rise to the Company's 
deferred tax asset are as follows as of December 31, 1996:

<PAGE>

Any tax benefits for the years ended December 31, 1996 and 1995 and the 
period March 25, 1993 (date of inception) through December 31, 1996 
computed based on statutory federal and state rates are completely offset 
by valuation allowances established since realization of the deferred tax 
benefits are not considered more likely than not.

5.  Common Stock Warrants:

During 1996 and 1995, the Company issued warrants to purchase 8,022 and 
7,608 shares, respectively, of common stock to the University of Florida 
Research Foundation ("UFRFI").  The warrants were issued as part of a 
license agreement with UFRFI whereby Ixion is authorized to occupy space 
at a UFRFI facility.  The agreement calls for the Company to pay $18 per 
square foot annually for the space that the Company currently occupies,  
payable at $11 per square foot in cash and $7 per square foot through 
issuance of common stock warrants.

For the 7,608 warrants issued in 1995, the value assigned was $1.00 per 
warrant and rent (prepaid or expense) was charged $7,608 related to this 
grant.  The value assigned to these warrants was based on the Company's 
assessment of fair value at the time of issuance.

The 8,022 warrants issued in connection with the UFRFI license agreement 
in 1996 are accounted for under the provisions of Statement of Financial 
Accounting Standards Board No. 123, Accounting for Stock Based 
Compensation.  This standard requires equity instruments issued in 
exchange for goods or services to be accounted for at the fair value of 
goods or services received or equity investments issued, whichever is 
more measurable.  In connection with the issuance of the 1996 warrants, 
the Company received cash license payment reductions of $10,857, the 
value assigned to the warrants, or $1.35 per warrant, which was charged 
to rent (prepaid or expense).
<PAGE>

5.  Common Stock Warrants - Continued:

In addition, during 1995, the Company issued warrants to purchase 2,000 
shares of common stock to an investor.  These warrants were issued under 
a subscription agreement for the purchase of 3,000 shares of common stock 
at $3.00 per share and warrants to purchase 2,000 shares of common stock 
at an exercise price of $2.00 per share.  The value assigned to the 
warrants, $1 per warrant, was based on the Company's assessment of fair 
value at the time of issuance.  The purchaser paid $5,000 in cash, and 
$6,000 in the form of a promissory note.

All common stock warrants outstanding as of December 31, 1996 are 
exercisable at a price of $2.00 per share and expire on August 31, 2000.

                                                                      10

6.  Stock Option Plan:

In August, 1994, the Board of Directors adopted the 1994 Stock Option 
Plan, under which 250,000 shares of common stock were reserved for 
issuance upon exercise of options granted to non-employee directors, 
officers, employees, members of the Scientific Advisory Board and 
consultants of the Company.  Options vest at the rate of 20% per year and 
are exercisable generally within ten years after date of grant.  Activity 
under the Company's stock option plan is set forth below:

The Company applies APB Opinion No. 25 and related Interpretations in 
accounting for stock issued to employees under this plan.  Compensation 
expense resulting from stock options is measured at the grant date based 
upon the difference between the exercise price and the market value of 
the common stock.  All stock options granted prior to December 15, 1995 
were granted at an exercise price equal to the market value at the date 
of grant.  Had compensation cost for the Company's stock-based 
compensation plan been determined based on the fair value at the grant 
dates for awards consistent with the method of FASB Statement No. 123, 
the Company's reported net loss and loss per share would not have been 
materially different.

7.  Board Retainer Plan:

The Company does not pay cash compensation to outside members of the 
Board of Directors or to members of the Company's Scientific Advisory 
Board.  Accordingly, in August, 1994, the Board of Directors adopted the 
1994 Board Retainer Plan, under which 75,000 shares of common stock were 
reserved for non-employee directors and members of the Scientific 
Advisory Board.

New outside members of the Board or the Scientific Advisory Board receive 
5,000 shares upon joining, and all will receive 5,000 shares annually 
during the pendency of the Board Retainer Plan.  Shares either vest upon 
delivery or time of service.  For the shares which vest over time of 
service, unearned compensation equivalent to the fair value at the date 
of grant is charged to capital deficiency and amortized over the service 
period to compensation expense.  Shares which vest upon delivery are 
recorded as compensation expense upon issuance.  At December 31, 1996, a 
total of 50,000 shares had been granted under this Plan.  Compensation 
expense recognized in connection with such awards for the years ending 
December 31, 1996 and 1995 was $139,295 and $7,500, respectively.  
Unearned compensation of $112,706 remains to be recognized as expense 
over future periods of service.


8.  Related-Party Transactions:

Commencing with the founding of the Company, two executives, the 
Chairman/Chief Executive Officer and the President, made loans to the 
Company pursuant to the terms of a convertible promissory note (the 
"Subordinated Note Agreement").  Under the terms of the Subordinated 
Notes, principal amounts were convertible into common stock at a price 
per share not greater than the lowest price per share (adjusted for stock 
splits, stock dividends, or other dilution) at which shares of the 
Company's common stock have been issued during the 12-month period 
immediately prior to the notice of election to convert.

                                                                        12
<PAGE>

On September 30, 1994, these officers each converted $9,000 of 
Subordinated Notes into an aggregate of 900,000 shares of the Company's 
common stock, at a price of $0.02 per share.  On June 30, 1996, the 
remaining obligation on these notes was converted by the officers into a 
total of 21,544 shares of the Company's common stock, at a price of $0.75 
per share.

In addition, the Company has agreed to defer the 1993, 1994 and part of 
the 1995 and 1996 salaries of the Chairman/Chief Executive Officer and 
the President pursuant to agreements between the Company and such 
executives.  Similar agreements are in effect with the Company's Senior 
Vice President and Chief Scientist.  Payments are to be made only upon 
termination of employment (which may be by death, disability, retirement, 
or otherwise) and may be in a lump sum or as an annuity.  Amounts bear 
interest, compounded annually, at a rate established by the Board of 
Directors, currently 8.0%.  These obligations are unfunded recorded 
liabilities of the Company.

On October 10, 1994, Dr. A.B. Peck, who is an executive officer and 
consultant, assigned to the Company all his interest in certain oxalate 
technology (subject to prior rights of the University of Florida) and 
agreed to an exclusive consulting agreement with the Company in exchange 
for an aggregate of 650,000 shares of common stock at a price of $0.02 
per share.

On November 10, 1994, members of the immediate families of the founders 
of the Company, including a partnership in which the Chairman/Chief 
Executive Officer has an undivided 25% interest, purchased an aggregate 
of 140,000 shares of the Company's common stock pursuant to an Agreement 
to Purchase Shares dated as of such date, for a price of $0.10 per share, 
or $14,000 in the aggregate.

On April 16, 1996, the Chairman/Chief Executive Officer and the President 
of the Company each entered into an agreement to extend the Company up to 
$25,000 in the form of a bridge loan.  Interest on the notes is at 8%, 
but can be reset annually, at the election of either party, to prime rate 
in effect on January 1 of any given year, plus 3%.  In addition, on June 
21, 1996, the Chairman/Chief Executive Officer agreed to increase his 
loan commitment to an amount up to $150,000, if necessary, to enable the 
Company to continue operations.  During 1996, no amounts are outstanding 
against either of these loan agreements as of December 31, 1996.

                                                                   13

9.  Sponsored Research Agreement:

On June 5, 1996, the Company entered into an agreement with Genetics 
Institute, Inc. ("GI") relating to Islet Producing Stem Cells Technology.  
Under the agreement, GI will sponsor certain research by the Company and 
will provide funding of $275,000 over a 12-month period, plus patent 
expenses of approximately $35,000.  The agreement may be extended, at 
GI's option, for up to two additional six-month periods.  GI will provide 
funding of $50,000 for each six-month extension.  The revenue under this 
contract is being recognized on a pro rata basis consistent with the 
period over which the research will be conducted as well as upon delivery 
of certain research reports.  As of December 31, 1996, the Company has 
recognized approximately $139,000 under the terms of this agreement, of 
which $14,000 represents reimbursable patent expenses incurred for the 
period.  In addition, as of December 31, 1996, the Company has recorded 
deferred revenue of $100,000 in connection with this agreement.

10.  Management's Plans:

The Company's financial statements for the year ended December 31, 1996 
have been prepared on a going concern basis, which contemplates the 
realization of assets and the settlement of liabilities and commitments 
in the normal course of business.  The Company incurred a net loss of 
$509,671 for the year ended December 31, 1996 and, as of December 31, 
1996, had a total capital deficiency of $569,319.

Management recognizes that the Company must generate additional resources 
or reduce operating costs to enable it to continue operations.  
Management's plans to secure other financing include a private placement, 
a public offering, bridge financing or corporate collaboration.  If none 
of these financing possibilities are concluded, then the Company would 
reduce ongoing operating expenses and seek loans from its officers in 
amounts that the Company considers necessary to sustain operations for 
the next year. 

11.  Risks and Uncertainties:

Approximately 80% of 1996 revenues consisted of revenues related to a 
single sponsored research agreement which expires in 1997 unless 
otherwise renewed.

The Company's product candidates are in an early stage of development.  
The Company has not completed the development of any products and, 
accordingly, has not received any regulatory approvals or commenced 
marketing activities.  No revenues have been generated from the sale of 
its products.

                                                                      14

11.  Risks and Uncertainties - Continued:

The Company's development and commercialization rights for its proposed 
products are derived from its license agreements with the University of 
Florida and others.  To date, the Company owns no patents outright.  A 
deterioration in the relationship between the Company and the University 
of Florida could have a material adverse effect on the Company.

The Company is aware of potentially significant risks regarding the 
patent rights licensed by the Company relating to Islet Progenitor/Stem 
Cells and to its oxalate technology.  The Company may not be able to 
commercialize its proposed diabetic products due to patent rights held by 
third parties other than the Company's licensors.

12.  Subsequent Events:

In February, 1997, the Company issued 1,000 shares of restricted common 
stock in exchange for a patent with a remaining legal life of 13 years.  
The patent was valued based on the Company's determination of the fair 
market value of the stock of $7.50 per share.  In addition to the 
issuance of stock, the Company will be required to pay royalties of 2% of 
net sales generated from the patented technology.

In February, 1997, the Company issued 10,000 shares of restricted common 
stock to an employee in exchange for entering into an employment 
agreement for future services.

In June, 1997, the Board of Directors authorized management of the 
Company to file a registration statement with the Securities and Exchange 
Commission permitting the Company to sell shares of its common stock in 
an initial public offering (the "IPO").

In April through June, 1997, the Board of Directors granted 25,400 options to
purchase shares of the Company's common stock at exercise prices ranging from
$6.00 to $10.00 per share.

In June, 1997, the Board of Directors issued an additional 7,000 shares of
stock under the Company's Board Retainer Plan.  Shares vest over periods
ranging from one to five years.

Ixion Biotechnology, Inc.
(A Development Stage Company)

Notes to Condensed Financial Statements

Three Month Periods Ended March 31, 1997

1.     Basis Of Presentation:

In the opinion of the Company, the accompanying unaudited financial 
statements contain all adjustments, consisting only of normal recurring 
accruals, necessary to present fairly the Company's financial position, 
results of operations and cash flows for the periods presented. The results 
of operations for the interim periods presented are not necessarily 
indicative of the results to be expected for the full year.

The condensed financial statements should be read in conjunction with the 
Company's annual financial statements for the year ended December 31, 1996.

2.     Income Taxes:

The components of the Company's net deferred tax asset and the tax effects 
of the primary temporary differences giving rise to the Company's deferred 
tax asset are as follows as of March 31, 1997:

Deferred compensation                      $155,000
Net operating loss carryforward             392,000

Deferred tax asset                          547,000
Valuation allowance                        (547,000)

Net deferred tax asset             $         -     

3.     Recent Accounting Pronouncements:

In February, 1997, the Financial Accounting Standards Board (FASB) issued 
Statement No. 128, Earnings Per Share. This statement, which is effective 
for the Company's annual report for the year ended December 31, 1997, 
establishes new requirements for the calculation, presentation and 
disclosure of earnings per share. The Company estimates that earnings per 
share presented in accordance with Statement No 128 would not differ 
materially from what is currently presented.

4.     Risks and Uncertainties:

Approximately 94% of revenues for the quarter ended March 31, 1997 
consisted of revenues related to a single sponsored research agreement 
which expires in 1997 unless otherwise renewed.

The Company's product candidates are in an early stage of development. The 
Company has not completed the development of any products and, accordingly, 
has not  received any regulatory approvals or commenced marketing 
activities. No revenues have been generated from the sale of its products

The Company's development and commercialization rights for its proposed 
products are derived from its license agreements with the University of 
Florida and others. To date, the Company owns no patents outright. A 
deterioration in the relationship between the Company and the University of 
Florida could have a material adverse effect on the Company.

5.     Risks and Uncertainties (continued):

The Company is aware of potentially significant risks regarding the patent 
rights licensed by the Company relating to Islet Progenitor Stem Cells and 
to its oxalate technology. The Company may not be able to commercialize 
its proposed diabetic products due to patent rights held by third parties 
other than the Company's licensors.

                                                Part II
                                  INFORMATION NOT REQUIRED IN PROSPECTUS

Item 24.  Indemnification of Directors and Officers.

     Under Delaware law, a corporation may indemnify any person who was or is 
a party or is threatened to be made a party to an action (other than an action 
by or in the right of the corporation) by reason of his service as a director 
or officer of the corporation, or his service, at the corporation's request, 
as a director, officer, employee or agent of another corporation or other 
enterprise, against expenses (including attorneys' fees) that are actually and 
reasonably incurred by him ("Expenses"), and judgments, fines and amounts paid 
in settlement that are actually and reasonably incurred by him, in connection 
with the defense or settlement of such action, provided that he acted in good 
faith and in a manner he reasonably believed to be in or not opposed to the 
corporation's best interests, and, with respect to any criminal action or 
proceeding, had no reasonable cause to believe that his conduct was unlawful.  
Although Delaware law permits a corporation to indemnify any person referred 
to above against Expenses in connection with the defense or settlement of an 
action by or in the right of the corporation, provided that he acted in good 
faith and in a manner he reasonably believed to be in or not opposed to the 
corporation's best interests, if such person has been judged liable to the 
corporation, indemnification is only permitted to the extent that the Court of 
Chancery (or the court in which the action was brought) determines that, 
despite the adjudication of liability, such person is entitled to indemnity 
for such Expenses as the court deems proper.  The General Corporation Law of 
the State of Delaware also provides for mandatory indemnification of any 
director, officer, employee or agent against Expenses to the extent such 
person has been successful in any proceeding covered by the statute.  In 
addition, the General Corporation Law of the State of Delaware provides the 
general authorization of advancement of a director's or officer's litigation 
expenses in lieu of requiring the authorization of such advancement by the 
board of directors in specific cases, and that indemnification and advancement 
of expenses provided by the statute shall not be deemed exclusive of any other 
rights to which those seeking indemnification or advancement of expenses may 
be entitled under any bylaw, agreement or otherwise.

     The Certificate of Incorporation (the "Certificate") of the Company 
provides that, to the fullest extent permitted by applicable law, as amended 
from time to time, the Company will indemnify any person who was or is a party 
or is threatened to be made a party to an action, suit or proceeding (whether 
civil, criminal, administrative or investigative) by reason of the fact that 
such person is or was director, officer, employee or agent of the Company or
serves or served any other enterprise at the request of the Company.

     In addition, the Certificate provides that a director of the Company 
shall not be personally liable to the Company or its stockholders for monetary 
damages for breach of the director's fiduciary duty.  However, the Certificate 
does not eliminate or limit the liability of a director for any of the 
following reasons: (i) a breach of the director's duty of loyalty to the 
Company or its stockholders; (ii) acts or omissions not in good faith or that 
involve intentional misconduct or knowing violation of law; or (iii) a 
transaction from which the director derived an improper personal benefit.

     The Company intends to purchase and maintain Directors' and Officers' 
Insurance as soon as the Board of Directors determines practicable, in amounts 
which they consider appropriate, insuring the directors against any liability 
arising out of the director's status as a director of the Company regardless 
of whether the Company has the power to indemnify the director against such 
liability under applicable law.

Item 26.  Recent Sales of Unregistered Securities.

     Set forth below is information as to securities sold by Ixion within the 
past three years which were not registered under the Securities Act of 1933 
(the "Act").  The Company issued all such securities in reliance upon Section 
4(2) under the Act.  The sales were conducted as non-public sales to a limited 
number of investors.  No underwriters were involved in any of the sales so 
there were no underwriting discounts or commissions.  All of such securities 
are deemed to be restricted securities for the purposes of the Securities Act.  
All certificates representing such issued and outstanding restricted 
securities of the Company have been properly legended and the Company has 
issued "stop transfer" instructions to its transfer agent with respect to such 
securities, which legends and stop transfer instructions are presently in 
effect unless such securities have been registered under the Securities Act or 
have been transferred pursuant to an appropriate exemption from the 
registration provisions of the Securities Act.

Item 28.     Undertakings.

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

     (b)  The Registrant hereby undertakes that for purposes of determining 
any liability under the Securities Act, (i) 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 Registrant 
pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be 
deemed to be part of this Registration Statement as of the time it was 
declared effective, and (ii) each post-effective amendment that contains a 
form of prospectus shall be deemed to be a new registration statement relating 
to the securities offered therein, and the offering of such securities at that 
time shall be deemed to be the initial bona fide offering thereof.

                                      OF
                          IXION BIOTECHNOLOGY, INC.

                                  __________

     The undersigned, a natural person, for the purpose of organizing a 
corporation for conducting the business and promoting the purposes hereinafter 
stated, under the provisions and subject to the requirements of the laws of 
the State of Delaware (particularly Chapter 1, Title 8 of the Delaware Code 
and the acts amendatory thereof and supplemental thereto, and known, 
identified, and referred to as the "General Corporation Law of the State of 
Delaware"), hereby certifies that:
     
     FIRST: The name of the corporation (hereinafter called the "corporation") 
is  IXION BIOTECHNOLOGY, INC. 

     SECOND: The address, including street, number, city, and county, of the 
registered office of the corporation in the State of Delaware is 32 Loockerman 
Square, Suite L-100, City of Dover 19901, County of Kent; and the name of the 
registered agent of the corporation in the State of Delaware at such address 
is The Prentice-Hall Corporation System, Inc. 

     THIRD: The purpose of the corporation is to engage in any lawful act or 
activity for which corporations may be organized under the General Corporation 
Law of the State of Delaware. 

     FOURTH: The total number of shares of stock which the corporation shall 
have authority to issue is one thousand, all of which are without par value. 
All such shares are of one class and are shares of Common Stock. 

     FIFTH: The name and the mailing address of the incorporator are as 
follows: 

     NAME                     MAILING ADDRESS 
Athena Amaxas               15 Columbus Circle 
New York, N.Y. 10023-7773 

     SIXTH: The corporation is to have perpetual existence. 

     SEVENTH: Whenever a compromise or arrangement is proposed between this 
corporation and its creditors or any class of them and/or between this 
corporation and its stockholders or any class of them, any court of equitable 
jurisdiction within the State of Delaware may, on the application in a summary 
way of this corporation or of any creditor or stockholder thereof or on the 
application of any receiver or receivers appointed for this corporation under 
the provisions of s 291 of Title 8 of the Delaware Code or on the application 
of trustees in dissolution or of any receiver or receivers appointed for this 
corporation under the provisions of s 279 of Title 8 of the Delaware Code 
order a meeting of the creditors or class of creditors, and/or of the 
stockholders or class of stockholders of this corporation, as the case may be, 
to be summoned in such manner as the said court directs. If a majority in 
number representing three fourths in value of the creditors or class of 
creditors, and/or of the stockholders or class of stockholders of this 
corporation, as the case may be, agree to any compromise or arrangement and to 
any reorganization of this corporation as consequence of such compromise or 
arrangement, the said compromise or arrangement and the said reorganization 
shall, if sanctioned by the court to which the said application has been made, 
be binding on all the creditors or class of creditors, and/or on all the 
stockholders or class of stockholders, of this corporation, as the case may 
be, and also on this corporation. 

     EIGHTH: For the management of the business and for the conduct of the 
affairs of the corporation, and in further definition, limitation, and 
regulation of the powers of the corporation and of its directors and of its 
stockholders or any class thereof, as the case may be, it is further provided: 
     1. The management of the business and the conduct of the affairs of 
the corporation shall be vested in its Board of Directors. The number of 
directors which shall constitute the whole Board of Directors shall be 
fixed by, or in the manner provided in, the Bylaws. The phrase "whole 
Board" and the phrase "total number of directors'' shall be deemed to 
have the same meaning, to wit, the total number of directors which the 
corporation would have if there were no vacancies. No election of 
directors need be by written ballot. 

     2. After the original or other Bylaws of the corporation have been 
adopted, amended, or repealed, as the case may be, in accordance with 
the provisions of s 109 of the General Corporation Law of the State of 
Delaware, and, after the corporation has received any payment for any of 
its stock, the power to adopt, amend, or repeal the Bylaws of the 
corporation may be exercised by the Board of Directors of the 
corporation; provided, however, that any provision for the 
classification of directors of the corporation for staggered terms 
pursuant to the provisions of subsection (d) of s 141 of the General 
Corporation Law of the State of Delaware shall be set forth in an 
initial Bylaw or in a Bylaw adopted by the stockholders entitled to vote 
of the corporation unless provisions for such classification shall be 
set forth in this certificate of incorporation. 

     3.  Whenever the corporation shall be authorized to issue only one 
class of stock, each outstanding share shall entitle the holder thereof 
to notice of, and the right to vote at, any meeting of stockholders. 
Whenever the corporation shall be authorized to issue more than one 
class of stock, no outstanding share of any class of stock which is 
denied voting power under the provisions of the certificate of 
incorporation shall entitle the holder thereof to the right to vote at 
any meeting of stockholders except as the provisions of paragraph (2) of 
subsection (b) of s 242 of the General Corporation Law of the State of 
Delaware shall otherwise require; provided, that no share of any such 
class which is otherwise denied voting power shall entitle the holder 
thereof to vote upon the increase or decrease in the number of 
authorized shares of said class. 

     NINTH: The personal liability of the directors of the corporation is 
hereby eliminated to the fullest extent permitted by the provisions of 
paragraph (7) of subsection (b) of s 102 of the General Corporation Law of the 
State of Delaware, as the same may be amended and supplemented. 

     TENTH: The corporation shall, to the fullest extent permitted by the 
provisions of s 145 of the General Corporation Law of the State of Delaware, 
as the same may be amended and supplemented, indemnify any and all persons 
whom it shall have power to indemnify under said section from and against any 
and all of the expenses, liabilities, or other matters referred to in or 
covered by said section, and the indemnification provided for herein shall not 
be deemed exclusive of any other rights to which those indemnified may be 
entitled under any Bylaw, agreement, vote of stockholders or disinterested 
directors or otherwise, both as to action in his official capacity and as to 
action in another capacity while holding such office, and shall continue as to 
a person who has ceased to be a director, officer, employee, or agent and 
shall inure to the benefit of the heirs, executors, and administrators of such 
a person. 

     ELEVENTH: From time to time any of the provisions of this certificate of 
incorporation may be amended, altered, or repealed, and other provisions 
authorized by the laws of the State of Delaware at the time in force may be 
added or inserted in the manner and at the time prescribed by said laws, and 
all rights at any time conferred upon the stockholders of the corporation by 
this certificate of incorporation are granted subject to the provisions of 
this Article ELEVENTH.

                         IXION BIOTECHNOLOGY, INC.
                         (a Delaware corporation)
                         (As of August 31, 1994)

                              ARTICLE I

                            STOCKHOLDERS

          1.  CERTIFICATES REPRESENTING STOCK.  Certificates representing 
stock in the corporation shall be signed by, or in the name of, the 
corporation by the Chairman or Vice-Chairman of the Board of Directors, if 
any, or by the President or a Vice-President and by the Treasurer or an 
Assistant Treasurer or the Secretary or an Assistant Secretary of the 
corporation.  Any or all the signatures on any such certificate may be a 
facsimile.  In case any officer, transfer agent, or registrar who has signed 
or whose facsimile signature has been placed upon a certificate shall have 
ceased to be such officer, transfer agent, or registrar before such 
certificate is issued, it may be issued by the corporation with the same 
effect as if he were such officer, transfer agent, or registrar at the date of 
issue.

          Whenever the corporation shall be authorized to issue more than one 
class of stock or more than one series of any class of stock, and whenever the 
corporation shall issue any shares of its stock as partly paid stock, the 
certificates representing shares of any such class or series or of any such 
partly paid stock shall set forth thereon the statements prescribed by the 
General Corporation Law.  Any restrictions on the transfer or registration of 
transfer of any shares of stock of any class or series shall be noted 
conspicuously on the certificate representing such shares.

     The corporation may issue a new certificate of stock or uncertificated 
shares in place of any certificate theretofore issued by it, alleged to have 
been lost, stolen, or destroyed, and the Board of Directors may require the 
owner of the lost, stolen, or destroyed certificate, or his legal 
representative, to give the corporation a bond sufficient to indemnify the 
corporation against any claim that may be made against it on account of the 
alleged loss, theft, or destruction of any such certificate or the issuance of 
any such new certificate or uncertificated shares.


          2.  UNCERTIFICATED SHARES.  Subject to any conditions imposed by the 
General Corporation Law, the Board of Directors of the corporation may provide 
by resolution or resolutions that some or all of any or all classes or series 
of the stock of the corporation shall be uncertificated shares.  Within a 
reasonable time after the issuance or transfer of any uncertificated shares, 
the corporation shall send to the registered owner thereof any written notice 
prescribed by the General Corporation Law.

          3.  FRACTIONAL SHARE INTERESTS.   The Corporation may, but shall not 
be required to, issue fractions of a share.  If the corporation does not issue 
fractions of a share, it shall (1) arrange for the disposition of fractional 
interests by those entitled thereto, (2) pay in cash the fair value of 
fractions of a share as of the time when those entitled to receive such 
fractions are determined, or (3) issue scrip or warrants in registered form 
(either represented by a certificate or uncertificated) or bearer form 
(represented by a certificate) which shall entitle the holder to receive a 
full share upon the surrender of such scrip or warrants aggregating a full 
share.  A certificate for a fractional share or an uncertificated fractional 
share shall, but scrip or warrants shall not unless otherwise provided 
therein, entitle the holder to exercise voting rights, to receive dividends 
thereon, and to participate in any of the assets of the corporation in the 
event of liquidation.  The Board of Directors may cause scrip or warrants to 
be issued subject to the conditions that they shall become void if not 
exchanged for certificates representing the full shares or uncertificated full 
shares before a specified date, or subject to the conditions that the shares 
for which scrip or warrants are exchangeable may be sold by the corporation 
and the proceeds thereof distributed to the holders of scrip or warrants, or 
subject to any other conditions which the Board of Directors may impose.

          4.  STOCK TRANSFERS.  Upon compliance with provisions restricting 
the transfer or registration of transfer of shares of stock, if any, transfers 
or registration of transfers of shares of stock of the corporation shall be 
made only on the stock ledger of the corporation by the registered holder 
thereof, or by his attorney thereunto authorized by power of attorney duly 
executed and filed with the Secretary of the corporation or with a transfer 
agent or a registrar, if any, and, in the case of shares represented by 
certificates, on surrender of the certificate or certificates for such shares 
of stock properly endorsed and the payment of all taxes due thereon.

          5.  RECORD DATE FOR STOCKHOLDERS.  In order that the corporation may 
determine the stockholders entitled to notice of or to vote at any meeting of 
stockholders or any adjournment thereof, the Board of Directors may fix a 
record date, which record date shall not precede the date upon which the 
resolution fixing the record date is adopted by the Board of Directors, and 
which record date shall not be more than sixty nor less than ten days before 
the date of such meeting.  If no record date is fixed by the Board of 
Directors, the record date for determining stockholders entitled to notice of 
or to vote at a meeting of stockholders shall be at the close of business on 
the day next preceding the day on which notice is given, or, if notice is 
waived, at the close of business on the day next preceding the day on which 
the meeting is held.  A determination of stockholders of record entitled to 
notice of or to vote at a meeting of stockholders shall apply to any 
adjournment of the meeting; provided, however, that the Board of Directors may 
fix a new record date for the adjourned meeting.  In order that the 
corporation may determine the stockholders entitled to consent to corporate 
action in writing without a meeting, the Board of Directors may fix a record 
date, which record date shall not precede the date upon which the resolution 
fixing the record date is adopted by the Board of Directors, and which date 
shall not be more than ten days after the date upon which the resolution 
fixing the record date is adopted by the Board of Directors.  If no record 
date has been fixed by the Board of Directors, the record date for determining 
the stockholders entitled to consent to corporate action in writing without a 
meeting, when no prior action by the Board of Directors is required by the 
General Corporation Law, shall be the first date on which a signed written 
consent setting forth the action taken or proposed to be taken is delivered to 
the corporation by delivery to its registered office in the State of Delaware, 
its principal place of business, or an officer or agent of the corporation 
having custody of the book in  which proceedings of meetings of stockholders 
are recorded.  Delivery made to the corporation's registered office shall be 
by hand or by certified or registered mail, return receipt requested.  If no 
record date has been fixed by the Board of Directors and prior action by the 
Board of Directors is required by the General Corporation Law, the record date 
for determining stockholders entitled to consent to corporate action in 
writing without a meeting shall be at the close of business on the day on 
which the Board of Directors adopts the resolution taking such prior action.  
In order that the corporation  may determine the stockholders entitled to 
receive payment of any dividend or other distribution or allotment of any 
rights or the stockholders entitled to exercise any rights in  respect of any 
change, conversion, or exchange of stock, or for the purpose of any other 
lawful action, the Board of Directors may fix a record date, which record date 
shall not precede the date upon which the resolution fixing the record date is 
adopted, and which record date shall be not more than sixty days prior to such 
action.  If no record date is fixed, the record date for determining 
stockholders for any such purpose shall be at the close of business on the day 
on which the Board of Directors adopts the resolution relating thereto.

          6.  MEANING OF CERTAIN TERMS.  As used herein in respect of the 
right to notice of a meeting of stockholders or a waiver thereof or to 
participate or vote thereat or to consent or dissent in writing in lieu of a 
meeting, as the case may be, the term "share" or "shares" or "share of stock" 
or "shares of stock" or "stockholder" or "stockholders" refers to an 
outstanding share or shares of stock and to a holder or holders of record of 
outstanding shares of stock when the corporation is authorized to issue only 
one class of shares of stock, and said reference is also intended to include 
any outstanding share or shares of stock and any holder or holders of record 
of outstanding shares of stock of any class upon which or upon whom the 
certificate of incorporation confers such rights where there are two or more 
classes or series of shares of stock or upon which or upon whom the General 
Corporation Law confers such rights notwithstanding that the certificate of 
incorporation may provide for more than one class or series of shares of 
stock, one or more of which are limited or denied such rights thereunder; 
provided, however, that no such right shall vest in the event of an increase 
or a decrease in the authorized number of shares of stock of any class or 
series which is otherwise denied voting rights under the provisions of the 
certificate of incorporation, except as any provision of law may otherwise 
require.

          7.  STOCKHOLDER MEETINGS.

          - TIME.  The annual meeting shall be held on the date and at the 
time fixed, from time to time, by the directors, provided, that the first 
annual meeting shall be held on a date within thirteen months after the 
organization of the corporation, and each successive annual meeting shall be 
held on a date within thirteen months after the date of the preceding annual 
meeting.  A special meeting shall be held on the date and at the time fixed by 
the directors.

          - PLACE.  Annual meetings and special meetings shall be held at such 
place, within or without the State of Delaware, as the directors may, from 
time to time, fix.  Whenever the directors shall fail to fix such place, the 
meeting shall be held at the registered office of the corporation in the State 
of Delaware.

          - CALL.  Annual meetings and special meetings may be called by the 
directors or by any officer instructed by the directors to call the meeting.

          - NOTICE OR WAIVER OF NOTICE.  Written notice of all meetings shall 
be given, stating the place, date, and hour of the meetings and stating the 
place within the city or other municipality or community at which the list of 
stockholders of the corporation may be examined.  The notice of an annual 
meetings shall state that the meeting is called for the election of directors 
and for the transaction of other business which may properly come before the 
meeting, and shall (if any other action which could be taken at a special 
meeting is to be taken at such annual meeting) state the purpose or purposes.  
The notice of a special meeting shall in all instances state the purpose or 
purposes for which the meeting is called.  The notice of any meeting shall 
also include, or be accompanied by, any additional statements, information, or 
documents prescribed by the General Corporation Law.  Except as otherwise 
provided by the General Corporation Law, a copy of the notice of any meeting 
shall be given, personally or by mail, not less than ten days nor more than 
sixty days before the date of the meeting, unless the lapse of the prescribed 
period of time shall have been waived, and directed to each stockholder at his 
record address or at such other address which he may have furnished by request 
in writing to the Secretary of the corporation.  Notice by mail shall be 
deemed to be given when deposited, with postage thereon prepaid, in the United 
States Mail.  If a meeting is adjourned to another time, not more than thirty 
days hence, and/or to another place, and if an announcement of the adjourned 
time and/or place is made at the meeting, it shall not be necessary to give 
notice of the adjourned meeting unless the directors, after adjournment, fix a 
new record date for the adjourned meeting.  Notice need not be given to any 
stockholder who submits a written waiver of notice signed by him before or 
after the time stated therein.  Attendance of a stockholder at a meeting of 
stockholders shall constitute a waiver of notice of such meeting, except when 
the stockholder attends the meeting for the express purpose of objecting, at 
the beginning of the meeting, to the transaction of any business because the 
meeting is not lawfully called or convened.  Neither the business to be 
transacted at, nor the purpose of, any regular or special meeting of the 
stockholders need be specified in any written waiver of notice.

          - STOCKHOLDER LIST.  The officer who has charge of the stock ledger 
of the corporation shall prepare and make, at least ten days before every 
meeting of stockholders, a complete list of the stockholders, arranged in 
alphabetical order, and showing the address of each stockholder and the number 
of shares registered in the name of each stockholder.  Such list shall be open 
to the examination of any stockholder, for any purpose germane to the meeting, 
during ordinary business hours, for a period of at least ten days prior to the 
meeting, either at a place within the city or other municipality or community 
where the meeting is to be held,  which place shall be specified in the notice 
of the meeting, or if not so specified, at the place where the meeting is to 
be held.  The list shall also be produced and kept at the time and place of 
the meeting during the whole time thereof, and may be inspected by any 
stockholder who is present.  The stock ledger shall be the only evidence as to 
who are the stockholders entitled to examine the stock ledger, the list 
required by this section or the books of the corporation, or to vote at any 
meeting of stockholders.

          - CONDUCT OF MEETING.  Meetings of the stockholders shall be 
presided over by one of the following officers in the order of seniority and 
if present and acting - the Chairman of the Board, if any, the Vice-Chairman 
of the Board, if any, the President, a Vice-President, or, if none of the 
foregoing is in office and present and acting, by a chairman to be chosen by 
the stockholders.  The Secretary of the corporation, or in his absence, an 
Assistant Secretary, shall act as secretary of every meeting, but if neither 
the Secretary nor an Assistant Secretary is present the Chairman of the 
meeting shall appoint a secretary of the meeting.

          - PROXY REPRESENTATION.  Every stockholder may authorize another 
person or persons to act for him by proxy in all matters in which a 
stockholder is entitled to participate, whether by waiving notice of any 
meeting, voting or participating at a meeting, or expressing consent or 
dissent without a meeting.  Every proxy must be signed by the stockholder or 
by his attorney-in-fact.  No proxy shall be voted or acted upon after three 
years from its date unless such proxy provides for a longer period.  A duly 
executed proxy shall be irrevocable if it states that it is irrevocable and, 
if, and only as long as, it is coupled with an interest sufficient in law to 
support an irrevocable power.  A proxy may be made irrevocable regardless of 
whether the interest with which is it coupled is an interest in the stock 
itself or an interest in the corporation generally.

          - INSPECTORS.  The directors, in advance of any meeting, may, but 
need not, appoint one or more inspectors of election to act at the meeting or 
any adjournment thereof.  If an inspector or inspectors are not appointed, the 
person presiding at the meeting may, but need not, appoint one or more 
inspectors.  In case any person who may be appointed as an inspector fails to 
appear or act, the vacancy may be filled by appointment made by the directors 
in advance of the meeting or at the meeting by the person presiding thereat.  
Each inspector, if any, before entering upon the discharge of his duties, 
shall take and sign an oath faithfully to execute the duties of inspectors at 
such meeting with strict impartiality and according to the best of his 
ability.  The inspectors, if any, shall determine the number of shares of 
stock outstanding and the voting power of each, the shares of stock 
represented at the meeting, the existence of a quorum, the validity and effect 
of proxies, and shall receive votes, ballots, or consents, hear and determine 
all challenges and questions arising in connection with the right to vote, 
count and tabulate all votes, ballots, or consents, determine the result, and 
do such acts as are proper to conduct the election or vote with fairness to 
all stockholders.  On request of the person presiding at the meeting, the 
inspector or inspectors, if any, shall make a report in writing of any 
challenge, question, or matter determined by him or them and execute a 
certificate of any fact found by him or them.  Except as otherwise required by 
subsection (e) of Section 231 of the General Corporation Law, the provisions 
of that Section shall not apply to the corporation.

          - QUORUM.  The holders of a majority of the outstanding shares of 
stock shall constitute a quorum at a meeting of stockholders for the 
transaction of any business.  The stockholders present may adjourn the meeting 
despite the absence of a quorum.

          - VOTING.  Each share of stock shall entitle the holder thereof to 
one vote.  Directors shall be elected by a plurality of the votes of the 
shares present in person or represented by proxy at the meeting and entitled 
to vote on the election of directors.  Any other action shall be authorized by 
a majority of the votes cast except where the General Corporation Law 
prescribes a different percentage of votes and/or a different exercise of 
voting power, and except as many be otherwise prescribed by the provisions of 
the certificate of incorporation and these Bylaws.  In the election of 
directors, and for any other action, voting need not be by ballot.

          8.  STOCKHOLDER ACTION WITHOUT MEETINGS.  Any action required by the 
General Corporation Law to be taken at any annual or special meeting of 
stockholders, or any action which may be taken at any annual or special 
meeting of stockholders, may be taken without a meeting, without prior notice 
and without a vote, if a consent in writing, setting forth the action so 
taken, shall be signed by the holders of outstanding stock having not less 
than the minimum number of votes that would be necessary to authorize or take 
such action at a meeting at which all shares entitled to vote thereon were 
present and voted.  Prompt notice of the taking of the corporate action 
without a meeting by less than unanimous written consent shall be given to 
those stockholders who have not consented in writing.  Action taken pursuant 
to this paragraph shall be subject to the provisions of Section 228 of the 
General Corporation Law.

                                  ARTICLE II

                                  DIRECTORS

          1.  FUNCTIONS AND DEFINITION.  The business and affairs of the 
corporation shall be managed by or under the direction of the Board of 
Directors of the corporation.  The Board of Directors shall have the authority 
to fix the compensation of the members thereof.  The use of the phrase "whole 
board" herein refers to the total number of directors which the corporation 
would have if there were no vacancies.


          2.  QUALIFICATIONS AND NUMBER.  A director need not be a 
stockholder, a citizen of the United  States, or a resident of the State of 
Delaware.  The initial Board of Directors shall consist of two persons.  
Thereafter the number of directors constituting the whole board shall be at 
least four.  Subject to the foregoing limitation and except for the first 
Board of Directors, such number may be fixed from time to time by action of 
the stockholders or of the directors, or, if the number if not fixed, the 
number shall be two.  The number of directors may be increased or decreased by 
action of the stockholders or of the directors.

[Number of directors increased to three by shareholders consent of April 
1, 1993 and to four by shareholder consent of April 16, 1994.]

          3.  ELECTION AND TERM.  The first Board of Directors, unless the 
members thereof shall have been named in the certificate of incorporation, 
shall be elected by the incorporator or incorporators and shall hold office 
until the first annual meeting of stockholders and until their successors are 
elected and qualified or until their earlier resignation or removal.  Any 
director may resign at any time upon written notice to the corporation.  
Thereafter, directors who are elected at an annual meeting of stockholders, 
and directors who are elected in the interim to fill vacancies and newly 
created directorships, shall hold office until the next annual meeting of 
stockholders and until their successors are elected and qualified or until 
their earlier resignation or removal.  Except as the General Corporation Law 
may otherwise require, in the interim between annual meetings of stockholders 
or of special meetings of stockholders called for the election of directors 
and/or for the removal of one or more directors and for the filling of any 
vacancy in that connection, newly created directorships and any vacancies in 
the Board of Directors, including unfilled by vacancies resulting from the 
removal of directors for cause or without cause, may be filled by the vote of 
a majority of the remaining directors then in office, although less than a 
quorum, or by the sole remaining director.

          4.  MEETINGS.

          - TIME.  Meetings shall be held at such time as the Board shall fix, 
except that the first meeting of a newly elected Board shall be held as soon 
after its election as the directors may conveniently assemble.

          - PLACE.  Meetings shall be held at such place within or without the 
State of  Delaware as shall be fixed by the Board.

          - CALL.  No call shall be required for regular meetings for which 
the time and place have been fixed.  Special meetings may be called by or at 
the direction of the Chairman of the Board, if any, the Vice-Chairman of the 
Board, if any, of the President, or of a majority of the directors in office.


          - NOTICE OR ACTUAL OR CONSTRUCTIVE WAIVER.  No notice shall be 
required for regular meetings for which the time and place have been fixed.  
Written, oral, or any other mode of notice of the time and place shall be 
given for special meetings in sufficient time for the convenient assembly of 
the directors thereat.  Notice need not be given to any director or to any 
member of a committee of directors who submits a written waiver of notice 
signed by him before or after the time stated therein.  Attendance of any such 
person at a meeting shall constitute a waiver of notice of such meeting, 
except when he attends a meeting for the express purpose of objecting, at the 
beginning of the meeting, to the transaction of any business because the 
meeting is not lawfully called or convened.  Neither the business to be 
transacted at, nor the purpose of, any regular or special meeting of the 
directors need be specified in any written waiver of notice.

          - QUORUM AND ACTION.  A majority of the whole Board shall constitute 
a quorum except when a vacancy or vacancies prevents such majority, whereupon 
a majority of the directors in office shall constitute a quorum, provided, 
that such majority shall constitute at least one-third of the whole Board.  A 
majority of the directors present, whether or not a quorum is present, may 
adjourn a meeting to another time and place.  Except as herein otherwise 
provided, and except as otherwise provided by the General Corporation Law, the 
vote of the majority of the directors present at a meeting at which a quorum 
is present shall be the act of the Board.  The quorum and voting provisions 
herein stated shall not be construed as conflicting with any provisions of the 
General Corporation Law and these Bylaws which govern a meeting of directors 
held to fill vacancies and newly created directorships in the Board or action 
of disinterested directors.

          Any member or members of the Board of Directors or of any committee 
designated by the Board, may participate in a meeting of the Board, or any 
such committee, as the case may be, by means of conference telephone or 
similar communications equipment by means of which all persons participating 
in the meeting can hear each other.

          - CHAIRMAN OF THE MEETING.  The Chairman of the Board, if any and if 
present and acting, shall preside at all meetings.  Otherwise, the Vice-
Chairman of the Board, if any and if present and acting, or the President, if 
present and acting, or any other director chosen by the Board, shall preside.

          5.  REMOVAL OF DIRECTORS.  Except as may otherwise be provided by 
the General Corporation Law, any director or the entire Board of Directors may 
be removed, with or without cause, by the holders of a majority of the shares 
then entitled to vote at an election of directors.

          6.  COMMITTEES.  The Board of Directors may, by resolution passed by 
a majority of the whole Board, designate one or more committees, each 
committee to consist of one or more of the directors of the corporation.  The 
Board may designate one or more directors as alternate members of any 
committee, who may replace any absent or disqualified member at any meeting of 
the committee.  In the absence or disqualification of any member of any such 
committee or committees, the member or members thereof present at any meeting 
and not disqualified from voting, whether or not he or they constitute a 
quorum, may unanimously appoint another member of the Board of Directors to 
act at the meeting in the place of any such absent or disqualified member.  
Any such committee, to the extent provided in the resolution of the Board, 
shall have and may exercise the powers and authority of the Board of Directors 
in the management of the business and affairs of the corporation with the 
exception of any authority the delegation of which is prohibited by Section 
141 of the General Corporation Law, and may authorize the seal of the 
corporation to be affixed to all papers which may require it.

[Executive Committee and Audit Benefits Committee established by Board 
by resolution dated April 16, 1994.]

          7.  WRITTEN ACTION.  Any action required or permitted to be taken at 
any meeting of the Board of Directors or any committee thereof may be taken 
without a meeting if all members of the Board or committee, as the case may 
be, consent thereto in writing, and the writing or writings are filed with the 
minutes of proceedings of the Board or committee.

                                 ARTICLE III

                                   OFFICERS

an Executive Vice-President, one or more other Vice-Presidents, one or more 
Assistant Secretaries, one or more Assistant Treasurers, and such other 
officers with such titles as the resolution of the Board of Directors choosing 
them shall designate.  Except as may otherwise be provided in the resolution 
of the Board of Directors choosing him, no officer other than the Chairman or 
Vice-Chairman of the Board, if any, need be a director.  Any number of offices 
may be held by the same person, as the directors may determine.

          Unless otherwise provided in the resolution choosing him, each 
officer shall be chosen for a term which shall continue until the meeting of 
the Board of Directors following the next annual meeting of stockholders and 
until his successor shall have been chosen and qualified.

          All officers of the corporation shall have such authority and 
perform such duties in the management and operation of the corporation as 
shall be prescribed in the resolutions of the Board of Directors designating 
and choosing such officers and prescribing their authority and duties, and 
shall have such additional authority and duties as are incident to their 
office except to the extent that such resolutions may be inconsistent 
therewith.  The Secretary or an Assistant Secretary of the corporation shall 
record all of the proceedings of all meetings and actions in writing of 
stockholders, directors, and committees of directors, and shall exercise such 
additional authority and perform such additional duties as the Board shall 
assign to him.  Any officer may be removed, with or without cause, by the 
Board of Directors.  Any vacancy in any office may be filled by the Board of 
Directors.  

          The Board of Directors may delegate to any officer or agent the 
power to appoint one or more Assistant Vice Presidents, one or more Assistant 
Treasurers, and one or more Assistant Secretaries and to prescribe their 
respective terms of office, authorities, and duties.  Any subordinate officer 
appointed pursuant to such delegation may be removed, either with or without 
cause, by the Board of Directors at any meeting, by the vote of a majority of 
the Board of Directors present at such meeting, or by any superior officer or 
agent upon whom such power of removal shall have been conferred by the Board 
of Directors.

[Addition to Bylaw Article III adopted by the Board of Directors on 
August 31, 1994.]

                                  ARTICLE IV

                                CORPORATE SEAL

shall prescribe.

                                  ARTICLE V

                                 FISCAL YEAR

          The fiscal year of the corporation shall be fixed, and shall be 
subject to change, by the Board of Directors.

                                  ARTICLE VI

                             CONTROL OVER BYLAWS

          Subject to the provisions of the certificate of incorporation and 
the provisions of the General Corporation Law, the power to amend, alter, or 
repeal these Bylaws and to adopt new Bylaws may be exercised by the Board of 
Directors or by the stockholders.

SECTION 2.  Charitable Benefit Warrants and Issuance of Warrant 
Certificates.

(a)  Each Charitable Benefit Warrant shall initially entitle any 
Approved Qualified Charitable Organization which is a Registered Holder of the 
Warrant Certificate representing such Charitable Benefit Warrant to purchase

issue Charitable Benefit Warrants to the purchasers thereof. 

(c) From time to time, up to the Warrant Expiration Date, the Warrant 
Agent shall countersign and deliver Warrant Certificates in required 
denominations of one or whole number multiples thereof to the person entitled 
thereto in connection with any transfer or exchange permitted under this 
Agreement.  Except as provided herein, no Warrant Certificates shall be issued

exercising Approved Qualified Charitable Organization Registered Holder, (ii) 
Warrant Certificates issued upon any transfer or exchange permitted under

Warrant Certificates in such form as may be approved by its Board of 
Directors, to reflect any adjustment or change in the Exercise Price or the 
number of shares of Common Stock purchasable upon exercise of the Charitable 
Benefit Warrants made pursuant to Section 8 hereof.

SECTION 3.  Form and Execution of Warrant Certificates.

(a) The Warrant Certificates shall be substantially in the form annexed 
hereto as Exhibit A (the provisions of which are hereby incorporated herein) 
and may have such letters, numbers or other marks of identification or 
designation and such legends, summaries or endorsements printed, lithographed 
or engraved thereon as the Company may deem appropriate and as are not 
inconsistent with the provisions of this Agreement, or as may be required to 
comply with any law or with any rule or regulation made pursuant thereto or to 
conform to usage.  The Warrant Certificates shall be dated the date of 
issuance thereof (whether upon initial issuance, transfer, exchange, or in 
lieu of mutilated, lost, stolen, or destroyed Warrant Certificates) and issued 
in registered form.  Charitable Benefit Warrants shall be numbered serially 
with the letter W on the Charitable Benefit Warrants.

(b) Warrant Certificates shall be executed on behalf of the Company by 
its Chairman of the Board, President, or any Vice President, and by its 
Treasurer or an Assistant Treasurer or its Secretary or an Assistant 
Secretary, by manual signatures or by facsimile signatures printed thereon. 
Warrant Certificates shall be manually countersigned by the Warrant Agent and 
shall not be valid for any purpose unless so countersigned.  In case any 
officer of the Company who shall have signed any of the Warrant Certificates 
shall cease to be such officer of the Company before the date of issuance of 
the Warrant Certificates or before countersignature by the Warrant Agent and 
issue and delivery thereof, such Warrant Certificates, nevertheless, may be 
countersigned by the Warrant Agent, issued and delivered with the same force 
and effect as though the person who signed such Warrant Certificates had not 
ceased to be such officer of the Company.  After countersignature by the 
Warrant Agent, Warrant Certificates shall be delivered by the Warrant Agent to 
the Registered Holder promptly and without further action by the Company, 
except as otherwise provided by Section 4(a) hereof.

SECTION 4.  Exercise.

(a) Charitable Benefit Warrants in denominations of one or whole number 
multiples thereof may be exercised only by an Approved Qualified Charitable 
Organization (as set forth on the listing of such organizations described in 
Section 9 hereof) which is the Registered Holder thereof commencing at any 
time or in part from time to time, but not after the Warrant Expiration Date, 
upon the terms and subject to the conditions set forth herein and in the 
applicable Warrant Certificate.  A Charitable Benefit Warrant shall be deemed 
to have been exercised immediately prior to the close of business on the 
Exercise Date and the person entitled to receive the securities deliverable 
upon such exercise shall be treated for all purposes as the holder, upon 
exercise thereof, as of the close of business on the Exercise Date.  If 
Charitable Benefit Warrants in denominations other than whole number multiples 
thereof shall be exercised at one time by the same Approved Qualified 
Charitable Organization Registered Holder, the number of full shares of Common 
Stock which shall be issuable upon exercise thereof shall be computed on the 
basis of the aggregate number of full shares of Common Stock issuable upon 
such exercise.  As soon as practicable on or after the Exercise Date and in 
any event within five business days after such date, if one or more Charitable 
Benefit Warrants have been exercised, the Warrant Agent on behalf of the 
Company shall cause to be issued to the person or persons entitled to receive 
the same, a Common Stock certificate or certificates for the shares of Common 
Stock deliverable upon such exercise, and the Warrant Agent shall deliver the 
same to the person or persons entitled thereto. Upon the exercise of any one 
or more Charitable Benefit Warrants, the Warrant Agent shall promptly notify 
the Company in writing of such fact and of the number of securities delivered 
upon such exercise and, subject to subsection (b) below, shall cause all 
payments or other amounts in cash or by check made payable to the order of the 
Company, equal to the Exercise Price, to be deposited promptly in the 
Company's bank account.

 (b)  The Company shall not issue fractional shares on the exercise of 
Charitable Benefit Warrants. If one or more Charitable Benefit Warrants shall 
be presented for exercise in full at the same time by the same Approved 
Qualified Charitable Organization Registered Holder, the number of whole 
shares which shall be issuable upon such exercise thereof shall be computed on 
the basis of the aggregate number of shares purchasable on exercise of the 
Charitable Benefit Warrants so presented and any fraction of a share shall be 
rounded up to the next whole share. 


SECTION 5.  Reservation of Shares; Listing; Payment of Taxes; etc.

(a) The Company covenants that it will at all times reserve and keep 
available out of its authorized Common Stock, solely for the purpose of issue 
upon exercise of Charitable Benefit Warrants, such number of shares of Common 
Stock as shall then be issuable upon the exercise of all outstanding 
Charitable Benefit Warrants. The Company covenants that all shares of Common 
Stock which shall be issuable upon exercise of the Charitable Benefit Warrants 
shall, at the time of delivery thereof, be duly and validly issued and fully 
paid and nonassessable and free from all preemptive or similar rights, taxes, 
liens, and charges with respect to the issue thereof, and that upon issuance 
such shares shall be listed on each securities exchange, if any, on which the 
other shares of outstanding Common Stock of the Company are then listed.

(b) The Company covenants that if any securities to be reserved for the 
purpose of exercise of Charitable Benefit Warrants hereunder require 
registration with, or approval of, any governmental authority under any 
federal securities law before such securities may be validly issued or 
delivered upon such exercise, then the Company will file a registration 
statement under the federal securities laws or a post-effective amendment, use 
its best efforts to cause the same to become effective and to keep such 
registration statement current while any of the Charitable Benefit Warrants 
are outstanding and deliver a prospectus which complies with Section 10(a)(3) 
of the Act, to the registered Holder exercising the Charitable Benefit Warrant 
(except, if in the opinion of counsel to the Company, such registration is not 
required under the Federal securities law or if the Company receives a letter 
from the staff of the Commission stating that it would not take any 
enforcement action if such registration is not effected).  The Company will 
use its best efforts to obtain appropriate approvals or registrations under 
state "blue sky" securities laws with respect to any such securities.  
However, Charitable Benefit Warrants may not be exercised by, or shares of 
Common Stock issued to, any Registered Holder in any state in which such 
exercise would be unlawful.

(c) The Company shall pay all documentary, stamp or similar taxes and 
other governmental charges that may be imposed with respect to the issuance of 
Charitable Benefit Warrants, or the issuance or delivery of any shares of 
Common Stock upon exercise of the Charitable Benefit Warrants; provided, 
however, that if shares of common Stock are to be delivered in a name other 
than the name of the Registered Holder of the Warrant Certificate representing 
any Charitable Benefit Warrant being exercised, then no such delivery shall be 
made unless the person requesting the same has paid to the Warrant Agent the 
amount of transfer taxes or charges incident thereto, if any.

(d) The Warrant Agent is hereby irrevocably authorized as the Transfer 
Agent to requisition from time to time certificates representing shares of 
Common Stock or other securities required upon exercise of the Charitable 
Benefit Warrants, and the Company will comply with all such requisitions.

SECTION 6.  Exchange and Registration of Transfer.

(a)  Warrant Certificates may be exchanged for other Warrant 
Certificates representing an equal aggregate number of Charitable Benefit 
Warrants of the same class.  Charitable Benefit Warrants may not be 
transferred in whole or in part except to an Approved Qualified Charitable 
Organization as set forth in the list described in Section 9 hereof, or to a 
testamentary trust, legatee, or heir by will or descent upon the death of a 
Registered Holder.  Warrant Certificates to be exchanged shall be surrendered 
to the Warrant Agent at its Corporate Office, and, upon satisfaction of the 
terms and provisions hereof, the Company shall execute and the Warrant Agent 
shall countersign, issue and deliver in exchange therefor the Warrant 
Certificate or Certificates which the Registered Holder making the exchange 
shall be entitled to receive.

(b)  The Warrant Agent shall keep, at its office, books in which, 
subject to such reasonable regulations as it may prescribe, it shall register 
Warrant Certificates and the transfer thereof in accordance with customary
practice and this Agreement.  Upon due presentment for registration of 
transfer of any Warrant Certificate at such office, the Company shall execute 
and the Warrant Agent shall issue and deliver to the transferee or transferees 
a new Warrant Certificate or Certificates representing an equal aggregate 
number of Charitable Benefit Warrants of the same class.

(c)  With respect to all Warrant Certificates presented for registration 
of transfer, or for exchange or exercise, the subscription or exercise form, 
as the case may be, on the reverse thereof shall be duly endorsed or be 
accompanied by a written instrument or instruments of transfer and 
subscription, in form satisfactory to the Company and the Warrant Agent, duly 
executed by the Registered Holder thereof or his attorney-in-fact duly 
authorized in writing.

(d) A service charge may be imposed by the Warrant Agent for any 
exchange or registration of transfer of Warrant Certificates.  In addition, 
the Company may require payment by such Holder of a sum sufficient to cover 
any tax or other governmental charge that may be imposed in connection 
therewith.

(e)  All Warrant Certificates surrendered for exercise or for exchange 
in case of mutilated Warrant Certificates shall be promptly canceled by the 
Warrant Agent and thereafter retained by the Warrant Agent until termination 
of this Agreement.

(f)  Prior to due presentment for registration of transfer thereof, the 
Company and the Warrant Agent may deem and treat the Registered Holder of any 
Warrant Certificate as the absolute owner thereof and of each Charitable 
Benefit Warrant represented thereby  (notwithstanding any notations of 
ownership or writing thereon made by anyone other than a duly authorized 
officer of the Company or the Warrant Agent) for all purposes and shall not be 
affected by any notice to the contrary.

SECTION 7.  Loss or Mutilation.  

Upon receipt by the Company and the Warrant Agent of evidence 
satisfactory to them of the ownership of and the loss, theft, destruction, or 
mutilation of any Warrant Certificate and (in the case of loss, theft, or 
destruction) of indemnity satisfactory to them, and (in case of mutilation) 
upon surrender and cancellation thereof, the Company shall execute and the 
Warrant Agent shall (in the absence of notice to the Company and/or the 
Warrant Agent that a new Warrant Certificate has been acquired by a bona fide 
Approved Qualified Charitable Organization) countersign and deliver to the 
Registered Holder in lieu thereof a new Warrant Certificate of like tenor 
representing an equal aggregate number of Charitable Benefit Warrants.  
Applicants for a substitute Warrant Certificate shall also comply with such 
other reasonable regulations and pay such other reasonable charges as the 
Warrant Agent may prescribe.

SECTION 8.  Adjustment of Exercise Price and Number of Shares of Common 
Stock Deliverable.

(a) Except as hereinafter provided, in the event the Company shall, at 
any time or from time to time after the date hereof issue any shares of Common 
Stock as a stock dividend to the holders of Common Stock, or subdivide or 
combine the outstanding shares of Common Stock into a greater or lesser number 
of shares (any such issuance, subdivision, or combination being herein called 
a "Change of Shares"), then, and thereafter upon each further Change of 
Shares, the Exercise Price for the Charitable Benefit Warrants (whether or not 
the same shall be issued and outstanding) in effect immediately prior to such 
Change of Shares shall be changed to a price (including any applicable 
fraction of a cent to the nearest cent) determined by dividing (i) the sum of 
(a) the total number of shares of Common Stock outstanding immediately prior 
to such Change of Shares, multiplied by the Exercise Price in effect 
immediately prior to such Change of Shares and (b) the consideration, if any,
received by the Company upon such sale, issuance, subdivision, or combination,
by (ii) the total number of shares of Common Stock outstanding immediately 
after such Change of Shares; provided, however, that in no event shall the 
Exercise Price be adjusted pursuant to this  computation to an amount in 
excess of the Exercise Price in effect immediately prior to such computation,
except in the case of a combination of outstanding shares of Common Stock.

For the purposes of any adjustment to be made in accordance with this 
Section 8(a), the following provisions shall be applicable:

(A) Shares of Common Stock issuable by way of dividend or other 
distribution on any stock of the Company shall be deemed to have been 
issued immediately after the opening of business on the day following 
the record date for the determination of shareholders entitled to 
receive such dividend or other distribution and shall be deemed to have 
been issued without consideration.

(B) The number of shares of Common Stock at any one time 
outstanding shall be deemed to include the aggregate maximum number of 
shares issuable (subject to readjustment upon the actual issuance 
thereof) upon the exercise of options, rights or warrants and upon the 
conversion or exchange of convertible or exchangeable securities.

(b) Upon each adjustment of the Exercise Price pursuant to this Section 
8, the number of shares of Common Stock purchasable upon the exercise of each 
Charitable Benefit Warrant shall be the number derived by multiplying the 
number of shares of common Stock purchasable immediately prior to such 
adjustment by the Exercise Price in effect prior to such adjustment and 
dividing the product so obtained by the applicable adjusted Exercise Price.

(c) In case of any reclassification or change of outstanding shares of 
Common Stock issuable upon exercise of the Charitable Benefit Warrants (other 
than a change in par value, or from par value to no par value, or from no par 
value to par value or as a result of a subdivision or combination), or in case 
of any consolidation or merger of the Company with or into another corporation 
(other than (1) a merger with a subsidiary of the Company in which merger the 
Company is the continuing corporation or (2) any consolidation or merger of 
the Company with or into another corporation which, in either instance, does 
not result in any reclassification or change of the then outstanding shares of 
Common Stock or other capital stock issuable upon exercise of the Charitable 
Benefit Warrants (other than a change in par value, or from par value to no 
par value, or from no par value to par value or as a result of subdivision or 
combination)) or in case of any sale or conveyance to another corporation of 
the property of the Company as an entirety or substantially as an entirety, 
then, as a condition of such reclassification, change, consolidation, merger, 
sale, or conveyance, the Company, or such successor or purchasing corporation, 
as the case may be, shall make lawful and adequate provision whereby the 
Registered Holder of each Charitable Benefit Warrant then outstanding shall 
have the right thereafter to receive on exercise of such Charitable Benefit 
Warrant the kind and amount of securities and property receivable upon such 
reclassification, change, consolidation, merger, sale, or conveyance by a 
holder of the number of securities issuable upon exercise of such Charitable 
Benefit Warrant immediately prior to such reclassification, change, 
consolidation, merger, sale, or conveyance and shall forthwith file at the 
Corporate Office of the Warrant Agent a statement signed by its Chairman, 
President, or a Vice President and by its Treasurer or an Assistant Treasurer 
or its Secretary or an Assistant Secretary evidencing such provision.  Such 
provisions shall include provision for adjustments which shall be as nearly 
equivalent as may be practicable to the adjustments provided for in Sections 
8(a) and (b).  The above provisions of this Section 8(c) shall similarly apply 
to successive reclassifications and changes of shares of Common Stock and to 
successive consolidations, mergers, sales or conveyances.

(d) Irrespective of any adjustments or changes in the Exercise Price or 
the number of shares of Common Stock purchasable upon exercise of the 
Charitable Benefit Warrants, the Warrant Certificates theretofore and 
thereafter issued shall, unless the Company shall exercise its option to issue 
new Warrant Certificates pursuant to Section 2(e) hereof, continue to express 
the Exercise Price per share and the number of shares purchasable thereunder 
as the Exercise Price per share and the number of shares purchasable 
thereunder were expressed in the warrant Certificates when the same were 
originally issued.

(e)  After each adjustment of the Exercise Price pursuant to this 
Section 8, the Company will promptly prepare a certificate signed by the 
Chairman, Chief Executive Officer or President, and by the Treasurer or an 
Assistant Treasurer or the Secretary or an Assistant Secretary, of the Company 
setting forth:  (i) the Exercise Price as so adjusted, (ii) the number of 
shares of Common Stock purchasable upon exercise of each Charitable Benefit 
Warrant, after such adjustment, and (iii) a brief statement of the facts 
accounting for such adjustment.  The Company will promptly file such 
certificate with the Warrant Agent and cause a brief summary thereof to be 
sent by ordinary first class mail to each Registered Holder at his last 
address as it shall appear on the registry books of the Warrant Agent.  No 
failure to mail such notice nor any defect therein or in the mailing thereof 
shall affect the validity thereof except as to the holder to whom the Company 
failed to mail such notice, or except as to the holder whose notice was 
defective.  The affidavit of an officer of the Warrant Agent or the Secretary 
or an Assistant Secretary of the Company that such notice has been mailed 
shall, in the absence of fraud, be prima facie evidence of the facts stated 
therein.

(f)  No adjustment of the Exercise Price shall be made as a result of or 
in connection with (A) the issuance or sale of shares of Common Stock pursuant 
to options, warrants, stock purchase agreements, and convertible or 
exchangeable securities outstanding or in effect on the date hereof and on the 
terms described in the Prospectus relating to the Public Offering; (B) stock 
options to be granted under the Company's 1994 Stock Option Plan to employees 
or consultants; (C) shares of Common Stock, options, or warrants issued to 
outside parties in connection with strategic alliances, joint ventures, or 
other corporate partnerships with the Company, or (D) the issuance of shares 
of Common Stock if the amount of said adjustment shall be less than $.10, 
provided, however, that in such case, any adjustment that would otherwise be 
required then to be made shall be carried forward and shall be made at the 
time of and together with the next subsequent adjustment that shall amount, 
together with any adjustment so carried forward, to at least $.10. In 
addition, prior to the exercise of any Charitable Benefit Warrant represented 
hereby, the Registered Holder shall not be entitled to any rights of a 
stockholder of the Company, including, without limitation, the right to vote 
or to receive dividends or other distributions, and shall not be entitled to 
receive any notice of any proceedings of the Company, except as provided in 
this Charitable Benefit Warrant Agreement.

SECTION 9.  Concerning Approved Qualified Charitable Organizations

(a) Charitable Benefit Warrants may only be transferred to, or exercised 
by, an Approved Qualified Charitable Organization; provided, however, that 
transfer to a testamentary trust, legatee, or heir by will or descent upon the 
death of a Registered Holder, will be permitted upon proper proof as decided 
by the Company.  

(b)  Qualified Charitable Organizations may be added to the approved 
list by the Company, in its absolute discretion, from time to time until the 
Warrant Expiration Date.  In order to be added to the approved list, a 
charitable organization must be tax exempt, and it must be eligible to receive 
tax deductible contributions in accordance with Section 170 of the Code.  
Charitable organizations may be added at the election of the Company, or they 
may be nominated by a Registered Holder.  Registered Holders wishing to 
nominate a charitable organization must send their nomination in writing to 
the Company, together with proof of such charitable organization's status as 
an organization described in Section 501(c)(3) of the Code which is excluded 
from the definition of a private foundation as referred to in Section 509(a) 
of the Code and which is eligible to receive tax deductible contributions in 
accordance with Section 170 of the Code. 

(c)  The Company shall provide to the Warrant Agent, from time to time, 
a statement, signed by its Chairman of the Board, President, or a Vice 
President and by its Treasurer or an Assistant Treasurer or its Secretary or 
an Assistant Secretary, setting forth the complete list of Approved Qualified 
Charitable Organizations.  The Warrant Agent shall not accept for transfer 
Charitable Benefit Warrants which attempt to transfer or assign such 
Charitable Benefit Warrants to any person other than an organization which is 
on the most recent list of Approved Qualified Charitable Organizations; 
provided, however, that transfer to a testamentary trust, legatee, or heir by 
will or descent upon the death of a Registered Holder, will be permitted upon 
proper proof as decided by the Company.  

(d)  Approved Qualified Charitable Organizations at the date of this 
agreement include the following:

          Juvenile Diabetes Foundation
          American Kidney Foundation
          Vulvar Pain Foundation
          National Vulvodynia Association

          Kidney Diseases
          North American Mycological Society
          University of Florida Research Foundation
          Florida Cystic Fibrosis, Inc.

SECTION 10.  Concerning the Warrant Agent.

(a)  The Warrant Agent acts hereunder as agent and in a ministerial 
capacity for the Company, and its duties shall be determined solely by the 
provisions hereof. The Warrant Agent shall not, by issuing and delivering 
Warrant Certificates or by any other act hereunder, be deemed to make any 
representations as to the validity or value or authorization of the Warrant 
Certificates or the Charitable Benefit Warrants represented thereby or of any 
securities or other property delivered upon exercise of any Charitable Benefit 
Warrant or whether any stock issued upon exercise of any Charitable Benefit 
Warrant is fully paid and nonassessable.

(b)  The Warrant Agent shall not at any time be under any duty or 
responsibility to any holder of Warrant Certificates to make or cause to be 
made any adjustment of the Exercise Price, or to determine whether any fact 
exists which may require any such adjustments, or with respect to the nature 
or extent of any such adjustments, when made, or with respect to the method 
employed in making the same. It shall not (i) be liable for any recital or 
statement of fact contained herein or for any action taken, suffered or 
omitted by it in reliance on any Warrant Certificate or other document or 
instrument believed by it in good faith to be genuine and to have been signed 
or presented by the proper party or parties, (ii) be responsible for any 
failure on the part of the Company to comply with any of its covenants and 
obligations contained in this Agreement or in any Warrant Certificate, or 
(iii) be liable for any act or omission in connection with this Agreement 
except for its own gross negligence, bad faith or willful misconduct.

(c)  The Warrant Agent may at any time consult with counsel satisfactory 
to it (who may be counsel for the Company) and shall incur no liability or 
responsibility for any action taken, suffered or omitted by it in good faith 
in accordance with the opinion or advice of such counsel.

(d)  Any notice, statement, instruction, request, direction, order or 
demand of the Company shall be sufficiently evidenced by an instrument signed 
by the Chairman of the Board of Directors, President, or any Vice President 
(unless other evidence in respect thereof is herein specifically prescribed). 
 The Warrant Agent shall not be liable for any action taken, suffered or 
omitted by it in accordance with such notice, statement, instruction, request, 
direction, order or demand reasonably believed by it to be genuine.

(e)  The Company agrees to pay the Warrant Agent reasonable compensation 
for its services hereunder and to reimburse it for its reasonable expenses 
hereunder; the Company further agrees to indemnify the Warrant Agent and save 
it harmless from and against any and all losses, expenses and liabilities, 
including judgments, costs and counsel fees, for anything done or omitted by 
the Warrant Agent in the execution of its duties and powers hereunder except 
losses, expenses and liabilities arising as a result of the Warrant Agent's 
gross negligence, bad faith or willful misconduct.

(f)  The Warrant Agent may resign its duties and be discharged from all 
further duties and liabilities hereunder (except liabilities arising as a 
result of the Warrant Agent's own gross negligence or willful misconduct), 
after giving 30 days' prior written notice to the Company.  At least 15 days 
prior to the date such resignation is to become effective, the Warrant Agent 
shall cause a copy of such notice of resignation to be mailed to the 
Registered Holder of each Warrant Certificate at the Company's expense.  Upon 
such resignation, or any inability of the Warrant Agent to act as such 
hereunder, the Company shall appoint in writing a new warrant agent.  If the 
Company shall fail to make such appointment within a period of 15 days after 
giving notice of such removal or after it has been notified in writing of such 
resignation or incapacity by  the resigning or incapacitated Warrant Agent, 
then the Company agrees to perform the duties of the Warrant Agent hereunder 
until a successor Warrant Agent is appointed.  After acceptance in writing of 
such appointment by the new warrant agent is received by the Company, such new 
warrant agent shall be vested with the same powers, rights, duties and 
responsibilities as if it had been originally named herein as the Warrant 
Agent, without any further assurance, conveyance, act or deed; but if for any 
reason it shall be necessary or expedient to execute and deliver any further 
assurance, conveyance, act or deed, the same shall be done at the expense of 
the Company and shall be legally and validly executed and delivered by the 
resigning Warrant Agent.  Not later than the effective date of any such 
appointment the Company shall file notice thereof with the resigning Warrant 
Agent and shall forthwith cause a copy of such notice to be mailed to the 
Registered Holder of each Warrant Certificate.

(g)  Any corporation into which the Warrant Agent or any new warrant 
agent may be converted or merged, any corporation resulting from any 
consolidation to which the Warrant Agent or any new warrant agent shall be a 
party, or any corporation succeeding to the corporate trust business of the 
Warrant Agent or any new warrant agent shall be a successor warrant agent 
under this Agreement without any further act, provided that such corporation 
is eligible for appointment as successor to the Warrant Agent under the 
provisions of the preceding paragraph.  Any such successor warrant agent shall 
promptly cause notice of its succession as warrant agent to be mailed to the 
Company and to the Registered Holders of each Warrant Certificate.

(h)  The Warrant Agent, its subsidiaries and affiliates, and any of its 
or their officers or directors, may buy and hold or sell securities of the 
Company and otherwise deal with the Company in the same manner and to the same 
extent and with like effect as though it were not Warrant Agent.  Nothing 
herein shall preclude the Warrant Agent from acting in any other capacity for 
the Company or for any other legal entity.

(i)  The Warrant Agent shall retain for a period of two years from the 
date of exercise any Warrant Certificate received by it upon such exercise.

SECTION 11.  Modification of Agreement.

The Warrant Agent and the Company may by supplemental agreement make any 
changes or corrections in this Agreement (i) that they shall deem appropriate 
to cure any ambiguity or to correct any defective or inconsistent provision or 
manifest mistake or error herein contained; or (ii) that they may deem 
necessary or desirable and which shall not adversely affect the interests of 
the holders of Warrant Certificates; provided, however, that no change in the 
number or nature of the securities purchasable upon the exercise of any 
Charitable Benefit Warrant, or to increase the Exercise Price therefor or to 
accelerate the Warrant Expiration Date, shall be made without the consent in 
writing of the Registered Holders representing not less than 66.667% of the 
Charitable Benefit Warrants then outstanding, other than such changes as are 
presently specifically prescribed by this Agreement as originally executed.

SECTION 12.  Notices.

All notices, requests, consents and other communications hereunder shall 
be in writing and shall be deemed to have been made when delivered or mailed 
first-class registered or certified mail, postage prepaid, or by fax as 
follows: if to the Registered Holder of a Warrant Certificate, at the address 
of such holder as shown on the registry books maintained by the Warrant Agent; 
if to the Company at 12085 Research Drive, Alachua, FL 32615, Fax 904-462-
0875, Attention: Weaver H. Gaines, Chairman and Chief Executive Officer, or at 
such other address  as may have been furnished to the Warrant Agent in writing 
by the Company; and if to the Warrant Agent, at its Corporate Office. 

SECTION 13.  Governing Law.

This Agreement shall be governed by and construed in accordance with the 
laws of the State of Florida without giving effect to conflicts of laws.

ARTICLE II

Duration and Exercise of Warrant

Section 2.01.     This Warrant may be exercised at any time after 9:00 a.m., 
Gainesville, Florida time, on July 1, 1995, and before 5:00 p.m., Gainesville, 
Florida time, on the Expiration Date.  If this Warrant is not exercised at or 
before 5:00 p.m., Gainesville, Florida time, on the Expiration Date, it will 
become void and neither the Warrant Holder nor any other person will have any 
rights under this Warrant.

Section 2.02.     (a)  To exercise this Warrant in whole or in part, the 
Warrant Holder must surrender this Warrant, with the Subscription Form duly 
executed, to the Company at its principal office accompanied by a certified or 
official bank check payable to the order of the Company in an amount equal to 
the aggregate Exercise Price for the shares of Common Stock as to which this 
Warrant is being exercised.

(b)     When the Company receives this Warrant with the Subscription Form duly 
executed and accompanied by payment of the aggregate Exercise Price for the 
shares of Common Stock as to which this Warrant is being exercised, the 
Company will promptly issue certificates, registered in the name of the 
Warrant Holder or such other names as are designated by the Warrant Holder, 
representing the total number of shares of Common Stock (and other securities, 
if any) as to which this Warrant is being exercised, in such denominations as 
are requested by the Warrant Holder, and the Company will deliver promptly 
such certificates to the Warrant Holder.

(c)     If the Warrant Holder exercises this Warrant with respect to fewer 
than all the shares of Common Stock to which it relates, the Company will 
execute a new Warrant for the balance of the shares of Common Stock that may 
be purchased upon exercise of this Warrant and will deliver promptly such new 
Warrant to the Warrant Holder.

(d)     The Company will pay any taxes that may be payable in respect of (i) 
the issuance of shares of Common Stock or (ii) the issuance of a new Warrant 
if this Warrant is exercised as to fewer than all the shares of Common Stock 
to which it relates.  The Company will not, however, be required to pay any 
transfer tax payable because shares of Common Stock or a new Warrant are to be 
registered in a name other than that of the Warrant Holder, and the Company 
will not be required to issue any shares of Common Stock or to issue a new 
Warrant registered in a name other than that of the Warrant Holder until (i) 
the Company receives either (A) evidence that any applicable transfer taxes 
have  been paid or (B) funds with which to pay those taxes or (ii) it has been 
established to the Company's satisfaction that no such tax is due.

ARTICLE III

Adjustment of Exercise Price 
and Number of Shares of Common Stock

Section 3.01.     The Exercise Price and the number of shares of Common Stock 
or other securities issuable on exercise of this Warrant are subject to 
adjustment as follows:

(a)     Changes in Common Stock.  In the event the Company shall, at any time 
or from time to time after the date hereof, (i) issue any shares of Common 
Stock as a stock dividend to the holders of Common Stock, (ii) subdivide or 
combine the outstanding shares of Common Stock into a greater or lesser number 
of shares or (iii) issue any shares of its capital stock in a 
reclassification, or reorganization of the Common Stock (any such issuance, 
subdivision, combination, reclassification, or reorganization being herein 
called a "Change of Shares"), then (A) in the case of (i) or (ii) above, the 
number of shares of Common Stock that may be purchased upon the exercise of 
this Warrant shall be adjusted to the number of shares of Common Stock that 
the Warrant Holder would have owned or have been entitled to receive after the 
happening of such event had this Warrant been exercised immediately prior to 
the record date (or, if there is no record date, the effective date) for such 
event, and the Exercise Price shall be adjusted to the price (calculated to 
the nearest 1,000th of one cent) determined by multiplying the Exercise Price 
immediately prior to such event by a fraction the numerator of which shall be 
the number of shares of Common Stock purchasable with this Warrant immediately 
prior to such event and the denominator of which shall be the number of shares 
purchasable with this Warrant after the adjustment referred to above and (B) 
in the case of (iii) above, paragraph (l) below shall apply.  An adjustment 
made pursuant to clause (A) of this paragraph shall become effective 
retroactively immediately after the record date in the case of a dividend and 
shall become effective immediately after the effective date in other cases.  
Any shares of Common Stock purchasable solely as a result of such adjustment 
shall not be issued prior to the effective date of such event.

(b)     Common Stock Distribution.  In the event the Company shall, at any 
time or from time to time after the date hereof, issue, sell, or otherwise 
distribute any shares of Common Stock (other than pursuant to a Change of 
Shares or the exercise of any Option, Convertible Security (each as defined in 
paragraph (c) and (d) below), or Warrant (any such event including any event 
described in paragraphs (c) and (d) below), being herein called a "Common 
Stock Distribution") for a consideration per share less than the current 
market price per share of Common Stock (as defined in paragraph (f) below) on 
the date of such Common Stock Distribution, then, effective upon such Common 
Stock Distribution, the Exercise Price shall be reduced to the price 
(calculated to the nearest 1,000th of one cent) determined by multiplying the 
Exercise Price in effect immediately prior to such Common Stock Distribution 
by a fraction, the numerator of which shall be the sum of (i) the number of 
shares of Common Stock outstanding (exclusive of any treasury shares) 
immediately prior to such Common Stock Distribution multiplied by the current 
market price per share of Common Stock on the date of such Common Stock 
Distribution, plus (ii) the consideration, if any, received by the Company 
upon such Common Stock Distribution, and the denominator of which shall be the 
product of (A) the total number of shares of Common Stock outstanding 
(exclusive of any treasury shares) immediately after such Common Stock 
Distribution multiplied by (B) the current market price per share of Common 
Stock on the date of such Common Stock Distribution.

If any Common Stock Distribution shall require an adjustment of the Exercise 
Price pursuant to the foregoing provisions of this paragraph (b), including by 
operation of paragraph (c) or (d) below, then, effective at the time such 
adjustment is made, the number of shares of Common Stock purchasable upon the 
exercise of this Warrant shall be increased to a number determined by 
multiplying the number of such shares so purchasable immediately prior to such 
Common Stock Distribution by a fraction, the numerator of which shall be the 
Exercise Price in effect immediately prior to such adjustment and the 
denominator of which shall be the Exercise Price in effect immediately after 
such adjustment.  In computing adjustments under this paragraph, fractional 
interests in Common Stock shall be taken into account to the nearest 1,000th 
of a share.
The provisions of this paragraph (b), including by operation of paragraph (c) 
or (d) below, shall not operate to increase the Exercise Price or reduce the 
number of shares of Common Stock purchasable upon the exercise of this 
Warrant.

(c)     Issuance of Options.  In the event the Company shall, at any time or 
from time to time after the date hereof, issue, sell, distribute, or otherwise 
grant in any manner (including by assumption) any rights to subscribe for or 
to purchase, or any warrants or options for the purchase of, Common Stock or 
any stock or securities convertible into or exchangeable for Common Stock (any 
such rights, warrants, or options being herein called "Options" and any such 
convertible or exchangeable stock or securities being herein called 
"Convertible Securities"), other than pursuant to its 1994 Stock Option Plan 
and its 1994 Board Retainer Plan, whether or not such Options or the rights to 
convert or exchange such Convertible Securities are immediately exercisable, 
and the price per share at which Common Stock is issuable upon the exercise of 
such Options or upon the conversion or exchange of such Convertible Securities 
(determined by dividing (i) the aggregate amount, if any, received or 
receivable by the Company as consideration for the issuance, sale, 
distribution, or granting of such Options, plus the minimum aggregate amount 
of additional consideration, if any, payable to the Company upon the exercise 
of all such Options, plus, in the cases of Options to acquire Convertible 
Securities, the minimum aggregate amount of additional consideration, if any, 
payable upon the conversion or exchange of all such Convertible Securities, by 
(ii) the total maximum number of shares of Common Stock issuable upon the 
exercise of all such Options or upon the conversion or exchange of all such 
Options or upon the conversion or exchange of all Convertible Securities 
issuable upon the exercise of all such Options) shall be less than the current 
market price per share of Common Stock on the date of the issuance, sale, 
distribution, or granting of such Options then, for purposes of paragraph (b) 
above, the total maximum number of shares of Common Stock issuable upon the 
exercise of all such Options or upon the conversion or exchange of the total 
maximum amount of the Convertible Securities issuable upon the exercise of all 
such Options) shall be less than the current market price per share of Common 
Stock on the date of the issuance, sale, distribution, or granting of such 
Options shall be deemed to have been issued as on the date of the issuance, 
sale, distribution, or granting of such Options and thereafter shall be deemed 
to be outstanding and the Company shall be deemed to have received as 
consideration such price per share, determined as provided above, therefor.  
Except as otherwise provided in paragraphs (j) and (k) below, no additional 
adjustment of the Exercise Price shall be made upon the actual exercise of 
such Options or upon conversion or exchange of the Convertible Securities 
issuable upon the exercise of such Options.

(d)     Issuance of Convertible Securities.  In the event the Company shall, 
at any time or from time to time after the date hereof, issue, sell, or 
otherwise distribute (including by assumption) any Convertible Securities 
(other than upon the exercise of any Option), whether or not the rights to 
convert or exchange such Convertible Securities are immediately exercisable, 
and the price per share at which Common Stock is issuable upon the conversion 
or exchange of such Convertible Securities (determined by dividing (i) the 
aggregate amount, if any, received or receivable by the Company as 
consideration for the issuance, sale, or distribution of such Convertible 
Securities, plus the minimum aggregate amount of additional consideration, if 
any, payable to the Company upon the conversion or exchange of all such 
Convertible Securities, by (ii) the total maximum number of shares of Common 
Stock issuable upon the conversion or exchange of all such Convertible 
Securities) shall be less than the current market price per share of Common 
Stock on the date of such issuance, sale, or distribution, then, for purposes 
of paragraph (b) above, the total maximum number of shares of Common Stock 
issuable upon the conversion or exchange of all such Convertible Securities 
shall be deemed to have been issued as of the date of the issuance, sale, or 
distribution of such Convertible Securities and thereafter shall be deemed to 
be outstanding and the Company shall be deemed to have received as 
consideration such price per share, determined as provided above, therefor.  
Except as otherwise provided in paragraphs (j) and (k) below, no additional 
adjustment of the Exercise Price shall be made upon the actual conversion or 
exchange of such Convertible Securities.

(e)     Dividends and Distributions.  In the event the Company shall, at any 
time or from time to time after the date hereof, distribute to the holders of 
Common Stock any dividend or other distribution of cash, evidences of its 
indebtedness, other securities, or other properties or assets (in each case 
other than (i) dividends payable in Common Stock, Options, or Convertible 
Securities and (ii) any cash dividend that, when added to all other cash 
dividends paid in the one year prior to the declaration date of such dividend 
(excluding any such other dividend included in a previous adjustment of the 
Exercise Price pursuant to this paragraph (e)), does not exceed 10% of the 
current market price per share of Common Stock on such declaration date), or 
any options, warrants, or other rights to subscribe for or purchase any of the 
foregoing, then (A) the Exercise Price shall be decreased to a price 
determined by multiplying  the Exercise Price then in effect by a fraction, 
the numerator of which shall be the current market price per share of Common 
Stock on the record date for such distribution less the sum of (X) the cash 
portion, if any, of such distribution per share of Common Stock outstanding 
(exclusive of any treasury shares) on the record date for such distribution 
plus (Y) the then fair market value (as determined in good faith by the Board 
of Directors of the Company) per share of Common Stock outstanding (exclusive 
of any treasury shares) on the record date for such distribution of that 
portion, if any, of such distribution consisting of evidences of indebtedness, 
other securities, properties, assets, options, warrants, or subscription or 
purchase rights, and the denominator of which shall be such current market 
price per share of Common Stock and (B) the number of shares of Common Stock 
purchasable upon the exercise of this Warrant shall be increased to a number 
determined by multiplying the number of shares of Common Stock so purchasable 
immediately prior to the record date for such distribution by a fraction, the 
numerator of which shall be the Exercise Price in effect immediately prior to 
the adjustment required by clause (A) of this sentence and the denominator of 
which shall be the Exercise Price in effect immediately after such adjustment.
The adjustments required by this paragraph (e) shall be made retroactive to 
the record date for the determination of stockholders entitled to receive such 
distribution.

(f)     Current Market Price.  For the purpose of any computation under 
paragraphs (b), (c), (d), and (e) of this Section 3.01, the current market 
price per share of Common Stock at any date shall be determined as follows:  
until the Company has raised an aggregate of $2,000,000 in sales of its 
securities, small business innovation research awards, small business 
technology transfer awards, or payments by corporate partners for research 
support or co-development (it being understood that at the date of this 
Warrant Agreement, the Company has already raised a total of $442,806, 
exclusive of deferred salaries), then the current market price per share 
(prior to any adjustment resulting from a Common Stock Distribution) shall be 
$2.00 per share; thereafter, the current market price per share of the Common 
Stock at any date shall be the average of the daily closing prices for the 
shorter of (i) the 20 consecutive trading days ending on the last full trading 
day on the exchange or market specified in the second succeeding sentence 
prior to the Time of Determination and (ii) the period commencing on the date 
next succeeding the first public announcement of the issuance, sale, 
distribution, or granting in question through such last full trading day prior 
to the Time of Determination.  The term "Time of Determination" as used herein 
shall be the time and date of the earlier to occur of (A) the date as of which 
the current market price is to be computed and (B) the last full trading day 
on such exchange or market before the commencement of "ex-dividend" trading in 
the Common Stock relating to the event giving rise to the adjustment required 
by paragraph (b), (c), (d), or (e).  The closing price for any day shall be 
the last reported sale price regular way or, in case no such reported sale 
takes place on such day, the average of the closing bid and asked prices 
regular way for such day, in each case (1) on the principal national 
securities exchange on which the shares of Common Stock are listed or to which 
such shares are admitted to trading or (2) if the Common Stock is not listed 
or admitted to trading on a national securities exchange, in the over-the-
counter market as reported by NASDAQ or any comparable system or (3) if the 
Common Stock is not listed on NASDAQ or a comparable system, as furnished by 
two members of the National Association of Securities Dealers, Inc. selected 
from time to time in good faith by the Board of Directors of the Company for 
that purpose.  In the absence of all of the foregoing or if for any other 
reason the current market price per share cannot be determined pursuant to the 
foregoing  provisions of this paragraph (f), the current market price per 
share shall be the fair market value thereof as determined in good faith by 
the Board of Directors of the Company.

(g)     Certain Distributions.  If the Company shall pay a dividend or make 
any other distribution payable in Options or Convertible Securities, then, for 
purposes of paragraph (b) above (by operation of paragraph (c) or (d) above, 
as the as may be), such Options or Convertible Securities shall be deemed to 
have been issued or sold without consideration.

(h)     Consideration Received.  If any shares of Common Stock, Options or 
Convertible Securities shall be issued, sold, or distributed for a 
consideration other than cash, the amount of the consideration other than cash 
received by the Company in respect thereof shall be deemed to be the then fair 
market value of such consideration (as determined in good faith by the Board 
of Directors of the Company).  If any Options shall be issued in connection 
with the issuance and sale of other securities of the Company, together 
comprising one integral transaction in which no specific consideration is 
allocated to such Options by the parties thereto, such Options shall be deemed 
to have been issued without consideration, provided, however, that if such 
Options have an exercise price equal to or greater than the current market 
price of the Common Stock on the date of issuance of such Options, then such 
Options shall be deemed to have been issued for consideration equal to such 
exercise price.

(i)     Deferral of Certain Adjustments.  No adjustment to the Exercise Price 
(including the related adjustment to the number of shares of Common Stock 
purchasable upon the exercise of this Warrant) shall be required hereunder 
unless such adjustment, together with other adjustments carried forward as 
provided below, would result in an increase or decrease of at least $.10 in 
the Exercise Price; provided however, that any adjustments which by reason of 
this paragraph (i) are not required to be made shall be carried forward and 
taken into account in any subsequent adjustment.  No adjustment need be made 
for a change in the par value of the Common Stock.

(j)     Changes in Options and Convertible Securities.  If the exercise price 
provided for in any Options referred to in paragraph (c) above, the additional 
consideration, if any, payable upon the conversion or exchange of any 
Convertible Securities referred to in paragraph (c) or (d) above, or the rate 
at which any Convertible Securities referred to in paragraph (c) or (d) above 
are convertible into or exchangeable for Common Stock shall change at any time 
(other than under or by reason of provisions designed to protect against 
dilution upon an event which results in a related adjustment pursuant to this 
Article III), the Exercise Price then in effect and the number of shares of 
Common Stock purchasable upon the exercise of this Warrant shall forthwith be 
readjusted (effective only with respect to any exercise of this Warrant after 
such readjustment) to the Exercise Price and number of shares of Common Stock 
so purchasable that would then be in effect had the adjustment made upon the 
issuance, sale, distribution, or granting of such Options or Convertible 
Securities been made based upon such changed purchase price, additional 
consideration, or conversion rate, as the case may be, but only with respect 
to such Options and Convertible Securities as then remain outstanding.

(k)     Expiration of Options and Convertible Securities.  If, at any time 
after any adjustment to the number of shares of Common Stock purchasable upon 
the exercise of this Warrant shall have been made pursuant to paragraph (c), 
(d), or (j) above or this paragraph (k), any Options or Convertible Securities 
shall have expired unexercised, the number of such shares so purchasable 
shall, upon such expiration, be readjusted and shall thereafter be such as 
they would have been had they been originally adjusted (or had the original 
adjustment not been required, as the case may be) as if (i) the only shares of 
Common Stock deemed to have been issued in connection with such options or 
Convertible Securities were the shares of Common Stock, if any, actually 
issued or sold upon the exercise of such Options or Convertible Securities and 
(ii) such shares of Common Stock, if any, were issued or sold for the 
consideration actually received by the Company upon such exercise plus the 
aggregate consideration, if any, actually received by the Company for the 
issuance, sale, distribution, or granting of all such Options of Convertible 
Securities, whether or not exercised; provided, however, that no such 
readjustment shall have the effect of decreasing the number of such shares so 
purchasable by an amount (calculated by adjusting such decrease to account for 
all other adjustments made pursuant to this Article III following the date of 
the original adjustment referred to above) in excess of the amount of the 
adjustment initially made in respect of the issuance, sale, distribution, or 
granting of such Options or Convertible Securities.

(l)     Other Adjustments.  In the event that at any time, as a result of an 
adjustment made pursuant to this Article III, the Warrant Holder shall become 
entitled to receive any securities of the Company other than shares of Common 
Stock, thereafter the number of such other securities so receivable upon 
exercise of this Warrant and the Exercise Price applicable to such exercise 
shall be subject to adjustment from time to time in a manner and on terms as 
nearly equivalent as practicable to the provisions with respect to the shares 
of Common Stock contained in this Article III.

Section 3.02.  Whenever the number of shares of Common Stock or other stock or 
property issuable upon the exercise of this Warrant is adjusted, as herein 
provided, the Company shall promptly mail to the Warrant Holder notice of such 
adjustment or adjustments and shall deliver to the Warrant Holder a 
certificate of a principal officer of the Company setting forth the number of 
shares of Common Stock or other stock or property issuable upon the exercise 
of this Warrant after such adjustment, setting forth a brief statement of the 
facts requiring such adjustment, and setting forth the computation by which 
such adjustment was made.

Section 3.03.  If at any time after this Warrant is first issued

(a)     the Company declares a dividend or other distribution on its Common 
Stock payable other than in cash out of its undistributed net income; or

(b)     the Company authorizes the granting to the holders of its Common Stock 
of rights to subscribe for a purchase any shares of any class of its capital 
stock or any other securities; or

(c)     there is any reclassification of the Common Stock (other than a 
subdivision or combination of its outstanding Common Stock), or any 
consolidation or merger to which the Company is a party and for which approval 
of the holders of the Common Stock is required, or a sale or transfer of all 
or substantially all the assets of the Company; or 

(d)     there is a voluntary or involuntary dissolution, liquidation, or 
winding up of the Company;

then, in each case, the Company will mail to the Warrant Holder at least 15 
Business Days before the applicable record date a notice stating (i) the 
record date for the dividend, distribution, or rights, or, if there will not 
be a record date, the date as of which the holders of record of Common Stock 
who will be entitled to the dividend, distribution, or rights will be 
determined, or (ii) the date on which the reclassification, consolidation, 
merger, sale, transfer, dissolution, liquidation, or winding up is expected to 
become effective, and the date as of which it is expected the holders of 
record of Common Stock who will be entitled to exchange their Common Stock for 
securities or other property as a result of the reclassification, 
consolidation, merger, sale, transfer, dissolution, liquidation, or winding up 
will be determined.  Failure to give any notice or any defect in the notice 
will not affect the validity of the action which should have been the subject 
of the notice.

Section 3.04.  The form of this Warrant need not be changed because of any 
change in the Warrant Price or in the number of shares of Common Stock which 
may be purchased by exercising this Warrant.  The Company may, however, at any 
time make any change in the form of Warrant this it deems appropriate to 
reflect a change in the Exercise Price or in the number of shares of Common 
Stock which may be purchased by exercising this Warrant (provided the change 
in the form of Warrant does not otherwise affect the substance of the 
Warrant), and any Warrant issued after the form of Warrant is so changed shall 
be in the changed form.



ARTICLE IV

Other Provisions Relating to Rights of the Warrant Holder

Section 4.01.  The Warrant Holder will not, as such, be entitled to vote, to 
receive dividends, or to have any other of the rights of a shareholder of the 
Company, except that after this Warrant is exercised in accordance with the 
terms of this Warrant the persons in whose names the shares of Common Stock 
purchased through exercise of this Warrant are to be issued will be deemed to 
become the holders of record of those shares of Common Stock for all purposes 
even if certificates representing such shares of Common Stock have not been 
issued.

Section 4.02.1 (a)  The Company will at all times reserve and keep available 
for issuance upon exercise of this Warrant the number of authorized and 
unissued shares of Common Stock equal to the maximum number of shares of 
Common Stock the Company may be required to issue upon exercise of this 
warrant at the Exercise Price in effect from time to time.

    (b)     All shares of Common Stock issued on exercise of this Warrant 
will, when they are issued, be validly issued, fully paid, and nonassessable.

Section 4.03.     The Company will not be required to issue any fraction of a 
share upon exercise of this Warrant.  If any fraction of a share of Common 
Stock would, except for the provisions of this Section, be issuable on the 
exercise of any Warrant (or specified portion thereof), the Company shall pay 
an amount in cash calculated by it to equal to the then current market value 
per share multiplied by such fraction computed to the nearest whole cent.  The 
Warrant Holder, by its acceptance of this Warrant, expressly waives any and 
all rights to receive any fraction of a share of Common Stock or a stock 
certificate representing a fraction of a share of Common Stock.     

Section 4.04.  The Company will maintain a Warrant Register in which the name 
and address of each registered holder of Warrants will be recorded.

Section 4.05.     Notices or other communications to the Warrant Holder will 
be deemed given by the Company on the third Business Day after the day on 
which they are sent by registered mail, return receipt requested, addressed to 
the Warrant Holder at the Warrant Holder's last known address shown on the 
Warrant Register.

Section 4.06.      Prior to due presentment for registration of transfer of 
this Warrant, the Company may treat the Warrant Holder as the absolute owner 
of this Warrant for all purposes, including  for the purpose of determining 
the persons entitled to exercise this Warrant, despite any notice to the 
contrary.

ARTICLE V

Transfer of Warrants

Section 5.01.     This Warrant may be sold, transferred, assigned, or 
hypothecated with the written consent of the Company, in whole or in part.  At 
all times, however, neither this Warrant nor the shares of Common Stock or 
other securities issuable upon exercise of this Warrant may be transferred 
except in a transaction which is registered under the Securities Act of 1933, 
as amended (the "Securities Act"), or which is exempt from the registration 
requirements of the Securities Act.

Section 5.02.     Upon surrender to the Company at its principal office of 
this Warrant with the Form of Assignment (or another instrument of assignment) 
duly executed and accompanied by (i) (A) evidence that any transfer tax has 
been paid or (B) funds sufficient to pay any transfer tax, or (C) evidence to 
the Company's satisfaction that no such tax is due, and (ii) evidence 
reasonably satisfactory to the Company that the proposed assignment will not 
violate Section 5.01, the Company will, without charge, execute and deliver a 
new Warrant registered in the name of the assignee named in the Form of 
Assignment (or other instrument of assignment) and will promptly cancel this 
Warrant.  This Warrant may be divided or combined with other Warrants by 
surrender of this Warrant and any other Warrants with which it is to be 
combined at the principal office of the Company together with a written 
notice, signed by the Warrant Holder, specifying the names and denominations 
in which new Warrants are to be issued.

Section 5.03.     Upon receipt by the Company of evidence reasonably 
satisfactory to it of the loss, theft, destruction, or mutilation of this 
Warrant, and (in the case of loss, theft, or destruction) of reasonably 
satisfactory indemnification, or (in the case of mutilation) upon surrender of 
this Warrant, the Company will execute and deliver a new Warrant relating to 
the same number of shares of Common Stock as this Warrant and the lost, 
stolen, destroyed, or mutilated Warrant will become void.  Any new Warrant 
executed and delivered in accordance with this Section 5.03 will constitute an 
additional contractual obligation of the Company, and will be valid and 
enforceable whether or not the Warrant which was believed to have been lost, 
stolen, or destroyed is subsequently presented for exercise.

ARTICLE VI

Registration Under the Securities Act

Section 6.01 (a) If, at any time during the period commencing on July 1, 1995 
and ending on June 30, 2001, The Company shall determine or be required to 
register any shares of the Company's Common Stock (whether on behalf of itself 
or any other person) under the Securities Act of 1933 on Forms S-1, S-2, S-3, 
SB-1, or SB-2 (or if such forms are rescinded by the Securities and Exchange 
Commission (the "Commission") such forms as replace those forms), excluding 
any registration for the offering and sale of securities of the Company to its 
employees, it will notify the Warrant Holder in order that it may request that 
all or a part of shares of Common Stock issued or issuable upon exercise of 
this Warrant be included in the registration statement.  If requested by any 
Warrant Holder in writing within 20 days after the Company's notice, the 
Company will include the requested number of shares in such registration 
statement.  Any such request shall include the agreement of the Warrant Holder 
requesting the registration to execute and deliver the underwriting agreement, 
if any, to be executed and delivered in connection with such registration.  
The Company may, however, decline to include all or a part of the requested 
number of shares in a registration statement pursuant to this section if it is 
advised by the investment banking firm managing the underwriting that such 
inclusion would adversely affect the offering of the shares to be covered by 
the proposed registration statement.

(b)     The Company shall use its best efforts to file such post-effective 
amendments to any registration statement described in this Section 6 as shall 
be necessary to keep it effective until six months after the effective date of 
the registration statement or the date on which all of the shares of the 
Warrant Holders covered thereunder shall have been sold, whichever is earlier.

(c)     As a condition to the Company's obligation under this Article VI to 
cause a registration statement or amendment to be filed or shares to be 
included in a registration statement, the Warrant Holder shall provide such 
information and execute such documents as may reasonably be required in 
connection with such registration.  In addition, the Company shall not be 
required to include such shares in a registration statement if it shall have 
received opinions of its and the Warrant Holder's counsel to the effect that 
the proposed disposition of such shares may be effected without registration 
under the Act.

(d)     The expenses of the registration of Warrant Holders' shares (other 
than transfer taxes, underwriting commissions, and fees of Warrant Holders' 
counsel) shall be paid by the Company.

Section 6.02.     Unless the resale of shares of Common Stock is the subject 
of an effective registration statement under the Securities Act, the 
certificates representing shares of Common Stock issued upon exercise of this 
Warrant may bear the following legend:

"THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE 
SECURITIES ACT OF 1933.   THE SHARES MAY NOT BE OFFERED OR SOLD, EXCEPT (i) 
PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT OR (ii) IN A TRANSACTION WHICH 
IS EXEMPT FROM THE REGISTRATION REQUIREMENTS OF THAT ACT."

                                  ARTICLE II

                       Duration and Exercise of Warrant

     Section 2.01.     This Warrant may be exercised at any time after 9:00 
a.m., Gainesville, Florida time, on July 1, 1995, and before 5:00 p.m., 
Gainesville, Florida time, on the Expiration Date.  If this Warrant is not 
exercised at or before 5:00 p.m., Gainesville, Florida time, on the Expiration 
Date, it will become void and neither the Warrant Holder nor any other person 
will have any rights under this Warrant.

     Section 2.02.     (a)  To exercise this Warrant in whole or in part, the 
Warrant Holder must surrender this Warrant, with the Subscription Form duly 
executed, to the Company at its principal office accompanied by a certified or 
official bank check payable to the order of the Company in an amount equal to 
the aggregate Exercise Price for the shares of Common Stock as to which this 
Warrant is being exercised.

          (b)     When the Company receives this Warrant with the Subscription 
Form duly executed and accompanied by payment of the aggregate Exercise Price 
for the shares of Common Stock as to which this Warrant is being exercised, 
the Company will promptly issue certificates, registered in the name of the 
Warrant Holder or such other names as are designated by the Warrant Holder, 
representing the total number of shares of Common Stock (and other securities, 
if any) as to which this Warrant is being exercised, in such denominations as 
are requested by the Warrant Holder, and the Company will deliver promptly 
such certificates to the Warrant Holder.

          (c)     If the Warrant Holder exercises this Warrant with respect to 
fewer than all the shares of Common Stock to which it relates, the Company 
will execute a new Warrant for the balance of the shares of Common Stock that 
may be purchased upon exercise of this Warrant and will deliver promptly such 
new Warrant to the Warrant Holder.

          (d)     The Company will pay any taxes that may be payable in 
respect of (i) the issuance of shares of Common Stock or (ii) the issuance of 
a new Warrant if this Warrant is exercised as to fewer than all the shares of 
Common Stock to which it relates.  The Company will not, however, be required 
to pay any transfer tax payable because shares of Common Stock or a new 
Warrant are to be registered in a name other than that of the Warrant Holder, 
and the Company will not be required to issue any shares of Common Stock or to 
issue a new Warrant registered in a name other than that of the Warrant Holder 
until (i) the Company receives either (A) evidence that any applicable 
transfer taxes have  been paid or (B) funds with which to pay those taxes or 
(ii) it has been established to the Company's satisfaction that no such tax is 
due.


                                 ARTICLE III

                        Adjustment of Exercise Price 
                     and Number of Shares of Common Stock

     Section 3.01.     The Exercise Price and the number of shares of Common 
Stock or other securities issuable on exercise of this Warrant are subject to 
adjustment as follows:

          (a)     Changes in Common Stock.  In the event the Company shall, at 
any time or from time to time after the date hereof, (i) issue any shares of 
Common Stock as a stock dividend to the holders of Common Stock, (ii) 
subdivide or combine the outstanding shares of Common Stock into a greater or 
lesser number of shares or (iii) issue any shares of its capital stock in a 
reclassification, or reorganization of the Common Stock (any such issuance, 
subdivision, combination, reclassification, or reorganization being herein 
called a "Change of Shares"), then (A) in the case of (i) or (ii) above, the 
number of shares of Common Stock that may be purchased upon the exercise of 
this Warrant shall be adjusted to the number of shares of Common Stock that 
the Warrant Holder would have owned or have been entitled to receive after the 
happening of such event had this Warrant been exercised immediately prior to 
the record date (or, if there is no record date, the effective date) for such 
event, and the Exercise Price shall be adjusted to the price (calculated to 
the nearest 1,000th of one cent) determined by multiplying the Exercise Price 
immediately prior to such event by a fraction the numerator of which shall be 
the number of shares of Common Stock purchasable with this Warrant immediately 
prior to such event and the denominator of which shall be the number of shares 
purchasable with this Warrant after the adjustment referred to above and (B) 
in the case of (iii) above, paragraph (l) below shall apply.  An adjustment 
made pursuant to clause (A) of this paragraph shall become effective 
retroactively immediately after the record date in the case of a dividend and 
shall become effective immediately after the effective date in other cases.  
Any shares of Common Stock purchasable solely as a result of such adjustment 
shall not be issued prior to the effective date of such event.

          (b)     Common Stock Distribution.  In the event the Company shall, 
at any time or from time to time after the date hereof, issue, sell, or 
otherwise distribute any shares of Common Stock (other than pursuant to a 
Change of Shares or the exercise of any Option, Convertible Security (each as 
defined in paragraph (c) and (d) below), or Warrant (any such event including 
any event described in paragraphs (c) and (d) below), being herein called a 
"Common Stock Distribution") for a consideration per share less than the 
current market price per share of Common Stock (as defined in paragraph (f) 
below) on the date of such Common Stock Distribution, then, effective upon 
such Common Stock Distribution, the Exercise Price shall be reduced to the 
price (calculated to the nearest 1,000th of one cent) determined by 
multiplying the Exercise Price in effect immediately prior to such Common 
Stock Distribution by a fraction, the numerator of which shall be the sum of 
(i) the number of shares of Common Stock outstanding (exclusive of any 
treasury shares) immediately prior to such Common Stock Distribution 
multiplied by the current market price per share of Common Stock on the date 
of such Common Stock Distribution, plus (ii) the consideration, if any, 
received by the Company upon such Common Stock Distribution, and the 
denominator of which shall be the product of (A) the total number of shares of 
Common Stock outstanding (exclusive of any treasury shares) immediately after 
such Common Stock Distribution multiplied by (B) the current market price per 
share of Common Stock on the date of such Common Stock Distribution.

          If any Common Stock Distribution shall require an adjustment of 
the Exercise Price pursuant to the foregoing provisions of this paragraph (b), 
including by operation of paragraph (c) or (d) below, then, effective at the 
time such adjustment is made, the number of shares of Common Stock purchasable 
upon the exercise of this Warrant shall be increased to a number determined by 
multiplying the number of such shares so purchasable immediately prior to such 
Common Stock Distribution by a fraction, the numerator of which shall be the 
Exercise Price in effect immediately prior to such adjustment and the 
denominator of which shall be the Exercise Price in effect immediately after 
such adjustment.  In computing adjustments under this paragraph, fractional 
interests in Common Stock shall be taken into account to the nearest 1,000th 
of a share.

          The provisions of this paragraph (b), including by operation of 
paragraph (c) or (d) below, shall not operate to increase the Exercise Price 
or reduce the number of shares of Common Stock purchasable upon the exercise 
of this Warrant.

          (c)     Issuance of Options.  In the event the Company shall, at any 
time or from time to time after the date hereof, issue, sell, distribute, or 
otherwise grant in any manner (including by assumption) any rights to 
subscribe for or to purchase, or any warrants or options for the purchase of, 
Common Stock or any stock or securities convertible into or exchangeable for 
Common Stock (any such rights, warrants, or options being herein called 
"Options" and any such convertible or exchangeable stock or securities being 
herein called "Convertible Securities"), other than pursuant to its 1994 Stock 
Option Plan and its 1994 Board Retainer Plan, whether or not such Options or 
the rights to convert or exchange such Convertible Securities are immediately 
exercisable, and the price per share at which Common Stock is issuable upon 
the exercise of such Options or upon the conversion or exchange of such 
Convertible Securities (determined by dividing (i) the aggregate amount, if 
any, received or receivable by the Company as consideration for the issuance, 
sale, distribution, or granting of such Options, plus the minimum aggregate 
amount of additional consideration, if any, payable to the Company upon the 
exercise of all such Options, plus, in the cases of Options to acquire 
Convertible Securities, the minimum aggregate amount of additional 
consideration, if any, payable upon the conversion or exchange of all such 
Convertible Securities, by (ii) the total maximum number of shares of Common 
Stock issuable upon the exercise of all such Options or upon the conversion or 
exchange of all such Options or upon the conversion or exchange of all 
Convertible Securities issuable upon the exercise of all such Options) shall 
be less than the current market price per share of Common Stock on the date of 
the issuance, sale, distribution, or granting of such Options then, for 
purposes of paragraph (b) above, the total maximum number of shares of Common 
Stock issuable upon the exercise of all such Options or upon the conversion or 
exchange of the total maximum amount of the Convertible Securities issuable 
upon the exercise of all such Options) shall be less than the current market 
price per share of Common Stock on the date of the issuance, sale, 
distribution, or granting of such Options shall be deemed to have been issued 
as on the date of the issuance, sale, distribution, or granting of such 
Options and thereafter shall be deemed to be outstanding and the Company shall 
be deemed to have received as consideration such price per share, determined 
as provided above, therefor.  Except as otherwise provided in paragraphs (j) 
and (k) below, no additional adjustment of the Exercise Price shall be made 
upon the actual exercise of such Options or upon conversion or exchange of the 
Convertible Securities issuable upon the exercise of such Options.

          (d)     Issuance of Convertible Securities.  In the event the 
Company shall, at any time or from time to time after the date hereof, issue, 
sell, or otherwise distribute (including by assumption) any Convertible 
Securities (other than upon the exercise of any Option), whether or not the 
rights to convert or exchange such Convertible Securities are immediately 
exercisable, and the price per share at which Common Stock is issuable upon 
the conversion or exchange of such Convertible Securities (determined by 
dividing (i) the aggregate amount, if any, received or receivable by the 
Company as consideration for the issuance, sale, or distribution of such 
Convertible Securities, plus the minimum aggregate amount of additional 
consideration, if any, payable to the Company upon the conversion or exchange 
of all such Convertible Securities, by (ii) the total maximum number of shares 
of Common Stock issuable upon the conversion or exchange of all such 
Convertible Securities) shall be less than the current market price per share 
of Common Stock on the date of such issuance, sale, or distribution, then, for 
purposes of paragraph (b) above, the total maximum number of shares of Common 
Stock issuable upon the conversion or exchange of all such Convertible 
Securities shall be deemed to have been issued as of the date of the issuance, 
sale, or distribution of such Convertible Securities and thereafter shall be 
deemed to be outstanding and the Company shall be deemed to have received as 
consideration such price per share, determined as provided above, therefor.  
Except as otherwise provided in paragraphs (j) and (k) below, no additional 
adjustment of the Exercise Price shall be made upon the actual conversion or 
exchange of such Convertible Securities.

          (e)     Dividends and Distributions.  In the event the Company 
shall, at any time or from time to time after the date hereof, distribute to 
the holders of Common Stock any dividend or other distribution of cash, 
evidences of its indebtedness, other securities, or other properties or assets 
(in each case other than (i) dividends payable in Common Stock, Options, or 
Convertible Securities and (ii) any cash dividend that, when added to all 
other cash dividends paid in the one year prior to the declaration date of 
such dividend (excluding any such other dividend included in a previous 
adjustment of the Exercise Price pursuant to this paragraph (e)), does not 
exceed 10% of the current market price per share of Common Stock on such 
declaration date), or any options, warrants, or other rights to subscribe for 
or purchase any of the foregoing, then (A) the Exercise Price shall be 
decreased to a price determined by multiplying  the Exercise Price then in 
effect by a fraction, the numerator of which shall be the current market price 
per share of Common Stock on the record date for such distribution less the 
sum of (X) the cash portion, if any, of such distribution per share of Common 
Stock outstanding (exclusive of any treasury shares) on the record date for 
such distribution plus (Y) the then fair market value (as determined in good 
faith by the Board of Directors of the Company) per share of Common Stock 
outstanding (exclusive of any treasury shares) on the record date for such 
distribution of that portion, if any, of such distribution consisting of 
evidences of indebtedness, other securities, properties, assets, options, 
warrants, or subscription or purchase rights, and the denominator of which 
shall be such current market price per share of Common Stock and (B) the 
number of shares of Common Stock purchasable upon the exercise of this Warrant 
shall be increased to a number determined by multiplying the number of shares 
of Common Stock so purchasable immediately prior to the record date for such 
distribution by a fraction, the numerator of which shall be the Exercise Price 
in effect immediately prior to the adjustment required by clause (A) of this 
sentence and the denominator of which shall be the Exercise Price in effect 
immediately after such adjustment.  The adjustments required by this paragraph 
(e) shall be made retroactive to the record date for the determination of 
stockholders entitled to receive such distribution.

          (f)     Current Market Price.  For the purpose of any computation 
under paragraphs (b), (c), (d), and (e) of this Section 3.01, the current 
market price per share of Common Stock at any date shall be determined as 
follows:  until the Company has raised an aggregate of $2,000,000 in sales of 
its securities, small business innovation research awards, small business 
technology transfer awards, or payments by corporate partners for research 
support or co-development (it being understood that at the date of this 
Warrant Agreement, the Company has already raised a total of $442,806, 
exclusive of deferred salaries), then the current market price per share 
(prior to any adjustment resulting from a Common Stock Distribution) shall be 
$2.00 per share; thereafter, the current market price per share of the Common 
Stock at any date shall be the average of the daily closing prices for the 
shorter of (i) the 20 consecutive trading days ending on the last full trading 
day on the exchange or market specified in the second succeeding sentence 
prior to the Time of Determination and (ii) the period commencing on the date 
next succeeding the first public announcement of the issuance, sale, 
distribution, or granting in question through such last full trading day prior 
to the Time of Determination.  The term "Time of Determination" as used herein 
shall be the time and date of the earlier to occur of (A) the date as of which 
the current market price is to be computed and (B) the last full trading day 
on such exchange or market before the commencement of "ex-dividend" trading in 
the Common Stock relating to the event giving rise to the adjustment required 
by paragraph (b), (c), (d), or (e).  The closing price for any day shall be 
the last reported sale price regular way or, in case no such reported sale 
takes place on such day, the average of the closing bid and asked prices 
regular way for such day, in each case (1) on the principal national 
securities exchange on which the shares of Common Stock are listed or to which 
such shares are admitted to trading or (2) if the Common Stock is not listed 
or admitted to trading on a national securities exchange, in the over-the-
counter market as reported by NASDAQ or any comparable system or (3) if the 
Common Stock is not listed on NASDAQ or a comparable system, as furnished by 
two members of the National Association of Securities Dealers, Inc. selected 
from time to time in good faith by the Board of Directors of the Company for 
that purpose.  In the absence of all of the foregoing or if for any other 
reason the current market price per share cannot be determined pursuant to the 
foregoing  provisions of this paragraph (f), the current market price per 
share shall be the fair market value thereof as determined in good faith by 
the Board of Directors of the Company.

          (g)     Certain Distributions.  If the Company shall pay a dividend 
or make any other distribution payable in Options or Convertible Securities, 
then, for purposes of paragraph (b) above (by operation of paragraph (c) or 
(d) above, as the as may be), such Options or Convertible Securities shall be 
deemed to have been issued or sold without consideration.

          (h)     Consideration Received.  If any shares of Common Stock, 
Options or Convertible Securities shall be issued, sold, or distributed for a 
consideration other than cash, the amount of the consideration other than cash 
received by the Company in respect thereof shall be deemed to be the then fair 
market value of such consideration (as determined in good faith by the Board 
of Directors of the Company).  If any Options shall be issued in connection 
with the issuance and sale of other securities of the Company, together 
comprising one integral transaction in which no specific consideration is 
allocated to such Options by the parties thereto, such Options shall be deemed 
to have been issued without consideration, provided, however, that if such 
Options have an exercise price equal to or greater than the current market 
price of the Common Stock on the date of issuance of such Options, then such 
Options shall be deemed to have been issued for consideration equal to such 
exercise price.

          (i)     Deferral of Certain Adjustments.  No adjustment to the 
Exercise Price (including the related adjustment to the number of shares of 
Common Stock purchasable upon the exercise of this Warrant) shall be required 
hereunder unless such adjustment, together with other adjustments carried 
forward as provided below, would result in an increase or decrease of at least 
$.10 in the Exercise Price; provided however, that any adjustments which by 
reason of this paragraph (i) are not required to be made shall be carried 
forward and taken into account in any subsequent adjustment.  No adjustment 
need be made for a change in the par value of the Common Stock.

          (j)     Changes in Options and Convertible Securities.  If the 
exercise price provided for in any Options referred to in paragraph (c) above, 
the additional consideration, if any, payable upon the conversion or exchange 
of any Convertible Securities referred to in paragraph (c) or (d) above, or 
the rate at which any Convertible Securities referred to in paragraph (c) or 
(d) above are convertible into or exchangeable for Common Stock shall change 
at any time (other than under or by reason of provisions designed to protect 
against dilution upon an event which results in a related adjustment pursuant 
to this Article III), the Exercise Price then in effect and the number of 
shares of Common Stock purchasable upon the exercise of this Warrant shall 
forthwith be readjusted (effective only with respect to any exercise of this 
Warrant after such readjustment) to the Exercise Price and number of shares of 
Common Stock so purchasable that would then be in effect had the adjustment 
made upon the issuance, sale, distribution, or granting of such Options or 
Convertible Securities been made based upon such changed purchase price, 
additional consideration, or conversion rate, as the case may be, but only 
with respect to such Options and Convertible Securities as then remain 
outstanding.

          (k)     Expiration of Options and Convertible Securities.  If, at 
any time after any adjustment to the number of shares of Common Stock 
purchasable upon the exercise of this Warrant shall have been made pursuant to 
paragraph (c), (d), or (j) above or this paragraph (k), any Options or 
Convertible Securities shall have expired unexercised, the number of such 
shares so purchasable shall, upon such expiration, be readjusted and shall 
thereafter be such as they would have been had they been originally adjusted 
(or had the original adjustment not been required, as the case may be) as if 
(i) the only shares of Common Stock deemed to have been issued in connection 
with such options or Convertible Securities were the shares of Common Stock, 
if any, actually issued or sold upon the exercise of such Options or 
Convertible Securities and (ii) such shares of Common Stock, if any, were 
issued or sold for the consideration actually received by the Company upon 
such exercise plus the aggregate consideration, if any, actually received by 
the Company for the issuance, sale, distribution, or granting of all such 
Options of Convertible Securities, whether or not exercised; provided, 
however, that no such readjustment shall have the effect of decreasing the 
number of such shares so purchasable by an amount (calculated by adjusting 
such decrease to account for all other adjustments made pursuant to this 
Article III following the date of the original adjustment referred to above) 
in excess of the amount of the adjustment initially made in respect of the 
issuance, sale, distribution, or granting of such Options or Convertible 
Securities.

          (l)     Other Adjustments.  In the event that at any time, as a 
result of an adjustment made pursuant to this Article III, the Warrant Holder 
shall become entitled to receive any securities of the Company other than 
shares of Common Stock, thereafter the number of such other securities so 
receivable upon exercise of this Warrant and the Exercise Price applicable to 
such exercise shall be subject to adjustment from time to time in a manner and 
on terms as nearly equivalent as practicable to the provisions with respect to 
the shares of Common Stock contained in this Article III.

     Section 3.02.  Whenever the number of shares of Common Stock or other 
stock or property issuable upon the exercise of this Warrant is adjusted, as 
herein provided, the Company shall promptly mail to the Warrant Holder notice 
of such adjustment or adjustments and shall deliver to the Warrant Holder a 
certificate of a principal officer of the Company setting forth the number of 
shares of Common Stock or other stock or property issuable upon the exercise 
of this Warrant after such adjustment, setting forth a brief statement of the 
facts requiring such adjustment, and setting forth the computation by which 
such adjustment was made.

     Section 3.03.  If at any time after this Warrant is first issued

          (a)     the Company declares a dividend or other distribution on its 
Common Stock payable other than in cash out of its undistributed net income; 
or
          (b)     the Company authorizes the granting to the holders of its 
Common Stock of rights to subscribe for a purchase any shares of any class of 
its capital stock or any other securities; or

          (c)     there is any reclassification of the Common Stock (other 
than a subdivision or combination of its outstanding Common Stock), or any 
consolidation or merger to which the Company is a party and for which approval 
of the holders of the Common Stock is required, or a sale or transfer of all 
or substantially all the assets of the Company; or 

          (d)     there is a voluntary or involuntary dissolution, 
liquidation, or winding up of the Company;

then, in each case, the Company will mail to the Warrant Holder at least 15 
Business Days before the applicable record date a notice stating (i) the 
record date for the dividend, distribution, or rights, or, if there will not 
be a record date, the date as of which the holders of record of Common Stock 
who will be entitled to the dividend, distribution, or rights will be 
determined, or (ii) the date on which the reclassification, consolidation, 
merger, sale, transfer, dissolution, liquidation, or winding up is expected to 
become effective, and the date as of which it is expected the holders of 
record of Common Stock who will be entitled to exchange their Common Stock for 
securities or other property as a result of the reclassification, 
consolidation, merger, sale, transfer, dissolution, liquidation, or winding up 
will be determined.  Failure to give any notice or any defect in the notice 
will not affect the validity of the action which should have been the subject 
of the notice.

     Section 3.04.  The form of this Warrant need not be changed because of 
any change in the Warrant Price or in the number of shares of Common Stock 
which may be purchased by exercising this Warrant.  The Company may, however, 
at any time make any change in the form of Warrant this it deems appropriate 
to reflect a change in the Exercise Price or in the number of shares of Common 
Stock which may be purchased by exercising this Warrant (provided the change 
in the form of Warrant does not otherwise affect the substance of the 
Warrant), and any Warrant issued after the form of Warrant is so changed shall 
be in the changed form.

                                  ARTICLE IV

          Other Provisions Relating to Rights of the Warrant Holder

     Section 4.01.  The Warrant Holder will not, as such, be entitled to 
vote, to receive dividends, or to have any other of the rights of a 
shareholder of the Company, except that after this Warrant is exercised in 
accordance with the terms of this Warrant the persons in whose names the 
shares of Common Stock purchased through exercise of 


this Warrant are to be issued will be deemed to become the holders of record 
of those shares of Common Stock for all purposes even if certificates 
representing such shares of Common Stock have not been issued.

     Section 4.02.1 (a)  The Company will at all times reserve and keep 
available for issuance upon exercise of this Warrant the number of authorized 
and unissued shares of Common Stock equal to the maximum number of shares of 
Common Stock the Company may be required to issue upon exercise of this 
warrant at the Exercise Price in effect from time to time.

              (b)     All shares of Common Stock issued on exercise of this 
Warrant will, when they are issued, be validly issued, fully paid, and 
nonassessable.

     Section 4.03.     The Company will not be required to issue any fraction 
of a share upon exercise of this Warrant.  If any fraction of a share of 
Common Stock would, except for the provisions of this Section, be issuable on 
the exercise of any Warrant (or specified portion thereof), the Company shall 
pay an amount in cash calculated by it to equal to the then current market 
value per share multiplied by such fraction computed to the nearest whole 
cent.  The Warrant Holder, by its acceptance of this Warrant, expressly waives 
any and all rights to receive any fraction of a share of Common Stock or a 
stock certificate representing a fraction of a share of Common Stock.     
     Section 4.04.  The Company will maintain a Warrant Register in which the 
name and address of each registered holder of Warrants will be recorded.

     Section 4.05.     Notices or other communications to the Warrant Holder 
will be deemed given by the Company on the third Business Day after the day on 
which they are sent by registered mail, return receipt requested, addressed to 
the Warrant Holder at the Warrant Holder's last known address shown on the 
Warrant Register.

     Section 4.06.      Prior to due presentment for registration of transfer 
of this Warrant, the Company may treat the Warrant Holder as the absolute 
owner of this Warrant for all purposes, including  for the purpose of 
determining the persons entitled to exercise this Warrant, despite any notice 
to the contrary.

                                  ARTICLE V

                             Transfer of Warrants

     Section 5.01.     This Warrant may be sold, transferred, assigned, or 
hypothecated with the written consent of the Company, in whole or in part.  At 
all times, however, neither this Warrant nor the shares of Common Stock or 
other securities issuable upon exercise of this Warrant may be transferred 
except in a transaction which is registered under the Securities Act of 1933, 
as amended (the "Securities Act"), or which is exempt from the registration 
requirements of the Securities Act.

     Section 5.02.     Upon surrender to the Company at its principal office 
of this Warrant with the Form of Assignment (or another instrument of 
assignment) duly executed and accompanied by (i) (A) evidence that any 
transfer tax has been paid or (B) funds sufficient to pay any transfer tax, or 
(C) evidence to the Company's satisfaction that no such tax is due, and (ii) 
evidence reasonably satisfactory to the Company that the proposed assignment 
will not violate Section 5.01, the Company will, without charge, execute and 
deliver a new Warrant registered in the name of the assignee named in the Form 
of Assignment (or other instrument of assignment) and will promptly cancel 
this Warrant.  This Warrant may be divided or combined with other Warrants by 
surrender of this Warrant and any other Warrants with which it is to be 
combined at the principal office of the Company together with a written 
notice, signed by the Warrant Holder, specifying the names and denominations 
in which new Warrants are to be issued.

     Section 5.03.     Upon receipt by the Company of evidence reasonably 
satisfactory to it of the loss, theft, destruction, or mutilation of this 
Warrant, and (in the case of loss, theft, or destruction) of reasonably 
satisfactory indemnification, or (in the case of mutilation) upon surrender of 
this Warrant, the Company will execute and deliver a new Warrant relating to 
the same number of shares of Common Stock as this Warrant and the lost, 
stolen, destroyed, or mutilated Warrant will become void.  Any new Warrant 
executed and delivered in accordance with this Section 5.03 will constitute an 
additional contractual obligation of the Company, and will be valid and 
enforceable whether or not the Warrant which was believed to have been lost, 
stolen, or destroyed is subsequently presented for exercise.

                                  ARTICLE VI

                    Registration Under the Securities Act

     Section 6.01 (a) If, at any time during the period commencing on July 1, 
1995 and ending on June 30, 2001, The Company shall determine or be required 
to register any shares of the Company's Common Stock (whether on behalf of 
itself or any other person) under the Securities Act of 1933 on Forms S-1, S-
2, S-3, SB-1, or SB-2 (or if such forms are rescinded by the Securities and 
Exchange Commission (the "Commission") such forms as replace those forms), 
excluding any registration for the offering and sale of securities of the 
Company to its employees, it will notify the Warrant Holder in order that it 
may request that all or a part of shares of Common Stock issued or issuable 
upon exercise of this Warrant be included in the registration statement.  If 
requested by any Warrant Holder in writing within 20 days after the Company's 
notice, the Company will include the requested number of shares in such 
registration statement.  Any such request shall include the agreement of the 
Warrant Holder requesting the registration to execute and deliver the 
underwriting agreement, if any, to be executed and delivered in connection 
with such registration.  The Company may, however, decline to include all or a 
part of the requested number of shares in a registration statement pursuant to 
this section if it is advised by the investment banking firm managing the 
underwriting that such inclusion would adversely affect the offering of the 
shares to be covered by the proposed registration statement.

          (b)     The Company shall use its best efforts to file such post-
effective amendments to any registration statement described in this Section 6 
as shall be necessary to keep it effective until six months after the 
effective date of the registration statement or the date on which all of the 
shares of the Warrant Holders covered thereunder shall have been sold, 
whichever is earlier.

          (c)     As a condition to the Company's obligation under this 
Article VI to cause a registration statement or amendment to be filed or 
shares to be included in a registration statement, the Warrant Holder shall 
provide such information and execute such documents as may reasonably be 
required in connection with such registration.  In addition, the Company shall 
not be required to include such shares in a registration statement if it shall 
have received opinions of its and the Warrant Holder's counsel to the effect 
that the proposed disposition of such shares may be effected without 
registration under the Act.

          (d)     The expenses of the registration of Warrant Holders' shares 
(other than transfer taxes, underwriting commissions, and fees of Warrant 
Holders' counsel) shall be paid by the Company.

     Section 6.02.     Unless the resale of shares of Common Stock is the 
subject of an effective registration statement under the Securities Act, the 
certificates representing shares of Common Stock issued upon exercise of this 
Warrant may bear the following legend:

"THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN 
REGISTERED UNDER THE SECURITIES ACT OF 1933.   THE SHARES MAY NOT 
BE OFFERED OR SOLD, EXCEPT (i) PURSUANT TO AN EFFECTIVE 
REGISTRATION STATEMENT OR (ii) IN A TRANSACTION WHICH IS EXEMPT 
FROM THE REGISTRATION REQUIREMENTS OF THAT ACT."

                                 ARTICLE VII
                                Other Matters

     Section 7.01.     The provisions of this Warrant will bind, and inure to 
the benefit of, the Company and its successors and assigns and the Warrant 
Holder and its successors and assigns.

     Section 7.02 (a)  Any notice or other communication to the Company 
relating to this Warrant will be deemed given on the day when it is delivered 
or sent by facsimile transmission (with a confirmation copy sent by registered 
mail, return receipt requested), or on the third Business Day after the day on 
which it is sent by registered mail, return receipt requested, to the Company 
at the following address (or such other address as may be specified by the 
Company after the date of this Warrant):

                 Executive Officer
          Facsimile No.  (904) 462-0875

          (b)     Any notice or other communication to the Warrant Holder will 
be deemed given when and as provided in Section 4.05.

     Section 7.03.     To the extent such documents are required to be sent 
by the Company to the holders of its outstanding Common Stock, the Company 
shall provide the Warrant Holder, within five Business Days after it files 
them with the Commission, copies of its annual report and of the information, 
documents, and other reports which the Company is required to file with the 
Commission pursuant to Section 13 or 15(d) of the Securities Exchange Act of 
1934.

     Section 7.04.     THIS WARRANT WILL BE GOVERNED BY, AND CONSTRUED UNDER, 
THE LAWS OF THE STATE OF FLORIDA RELATING TO CONTRACTS AND INSTRUMENTS 
EXECUTED AND TO BE PERFORMED ENTIRELY IN SUCH STATE.

                                  ARTICLE II

                       Duration and Exercise of Warrant

     Section 2.01.     This Warrant may be exercised at any time after 9:00 
a.m., Gainesville, Florida time, on July 1, 1995, and before 5:00 p.m., 
Gainesville, Florida time, on the Expiration Date.  If this Warrant is not 
exercised at or before 5:00 p.m., Gainesville, Florida time, on the Expiration 
Date, it will become void and neither the Warrant Holder nor any other person 
will have any rights under this Warrant.

     Section 2.02.     (a)  To exercise this Warrant in whole or in part, the 
Warrant Holder must surrender this Warrant, with the Subscription Form duly 
executed, to the Company at its principal office accompanied by a certified or 
official bank check payable to the order of the Company in an amount equal to 
the aggregate Exercise Price for the shares of Common Stock as to which this 
Warrant is being exercised.

          (b)     When the Company receives this Warrant with the Subscription 
Form duly executed and accompanied by payment of the aggregate Exercise Price 
for the shares of Common Stock as to which this Warrant is being exercised, 
the Company will promptly issue certificates, registered in the name of the 
Warrant Holder or such other names as are designated by the Warrant Holder, 
representing the total number of shares of Common Stock (and other securities, 
if any) as to which this Warrant is being exercised, in such denominations as 
are requested by the Warrant Holder, and the Company will deliver promptly 
such certificates to the Warrant Holder.

          (c)     If the Warrant Holder exercises this Warrant with respect to 
fewer than all the shares of Common Stock to which it relates, the Company 
will execute a new Warrant for the balance of the shares of Common Stock that 
may be purchased upon exercise of this Warrant and will deliver promptly such 
new Warrant to the Warrant Holder.

          (d)     The Company will pay any taxes that may be payable in 
respect of (i) the issuance of shares of Common Stock or (ii) the issuance of 
a new Warrant if this Warrant is exercised as to fewer than all the shares of 
Common Stock to which it relates.  The Company will not, however, be required 
to pay any transfer tax payable because shares of Common Stock or a new 
Warrant are to be registered in a name other than that of the Warrant Holder, 
and the Company will not be required to issue any shares of Common Stock or to 
issue a new Warrant registered in a name other than that of the Warrant Holder 
until (i) the Company receives either (A) evidence that any applicable 
transfer taxes have  been paid or (B) funds with which to pay those taxes or 
(ii) it has been established to the Company's satisfaction that no such tax is 
due.


                                 ARTICLE III

                        Adjustment of Exercise Price 
                     and Number of Shares of Common Stock

     Section 3.01.     The Exercise Price and the number of shares of Common 
Stock or other securities issuable on exercise of this Warrant are subject to 
adjustment as follows:

          (a)     Changes in Common Stock.  In the event the Company shall, at 
any time or from time to time after the date hereof, (i) issue any shares of 
Common Stock as a stock dividend to the holders of Common Stock, (ii) 
subdivide or combine the outstanding shares of Common Stock into a greater or 
lesser number of shares or (iii) issue any shares of its capital stock in a 
reclassification, or reorganization of the Common Stock (any such issuance, 
subdivision, combination, reclassification, or reorganization being herein 
called a "Change of Shares"), then (A) in the case of (i) or (ii) above, the 
number of shares of Common Stock that may be purchased upon the exercise of 
this Warrant shall be adjusted to the number of shares of Common Stock that 
the Warrant Holder would have owned or have been entitled to receive after the 
happening of such event had this Warrant been exercised immediately prior to 
the record date (or, if there is no record date, the effective date) for such 
event, and the Exercise Price shall be adjusted to the price (calculated to 
the nearest 1,000th of one cent) determined by multiplying the Exercise Price 
immediately prior to such event by a fraction the numerator of which shall be 
the number of shares of Common Stock purchasable with this Warrant immediately 
prior to such event and the denominator of which shall be the number of shares 
purchasable with this Warrant after the adjustment referred to above and (B) 
in the case of (iii) above, paragraph (l) below shall apply.  An adjustment 
made pursuant to clause (A) of this paragraph shall become effective 
retroactively immediately after the record date in the case of a dividend and 
shall become effective immediately after the effective date in other cases.  
Any shares of Common Stock purchasable solely as a result of such adjustment 
shall not be issued prior to the effective date of such event.

          (b)     Common Stock Distribution.  In the event the Company shall, 
at any time or from time to time after the date hereof, issue, sell, or 
otherwise distribute any shares of Common Stock (other than pursuant to a 
Change of Shares or the exercise of any Option, Convertible Security (each as 
defined in paragraph (c) and (d) below), or Warrant (any such event including 
any event described in paragraphs (c) and (d) below), being herein called a 
"Common Stock Distribution") for a consideration per share less than the 
current market price per share of Common Stock (as defined in paragraph (f) 
below) on the date of such Common Stock Distribution, then, effective upon 
such Common Stock Distribution, the Exercise Price shall be reduced to the 
price (calculated to the nearest 1,000th of one cent) determined by 
multiplying the Exercise Price in effect immediately prior to such Common 
Stock Distribution by a fraction, the numerator of which shall be the sum of 
(i) the number of shares of Common Stock outstanding (exclusive of any 
treasury shares) immediately prior to such Common Stock Distribution 
multiplied by the current market price per share of Common Stock on the date 
of such Common Stock Distribution, plus (ii) the consideration, if any, 
received by the Company upon such Common Stock Distribution, and the 
denominator of which shall be the product of (A) the total number of shares of 
Common Stock outstanding (exclusive of any treasury shares) immediately after 
such Common Stock Distribution multiplied by (B) the current market price per 
share of Common Stock on the date of such Common Stock Distribution.

          If any Common Stock Distribution shall require an adjustment of 
the Exercise Price pursuant to the foregoing provisions of this paragraph (b), 
including by operation of paragraph (c) or (d) below, then, effective at the 
time such adjustment is made, the number of shares of Common Stock purchasable 
upon the exercise of this Warrant shall be increased to a number determined by 
multiplying the number of such shares so purchasable immediately prior to such 
Common Stock Distribution by a fraction, the numerator of which shall be the 
Exercise Price in effect immediately prior to such adjustment and the 
denominator of which shall be the Exercise Price in effect immediately after 
such adjustment.  In computing adjustments under this paragraph, fractional 
interests in Common Stock shall be taken into account to the nearest 1,000th 
of a share.

          The provisions of this paragraph (b), including by operation of 
paragraph (c) or (d) below, shall not operate to increase the Exercise Price 
or reduce the number of shares of Common Stock purchasable upon the exercise 
of this Warrant.

          (c)     Issuance of Options.  In the event the Company shall, at any 
time or from time to time after the date hereof, issue, sell, distribute, or 
otherwise grant in any manner (including by assumption) any rights to 
subscribe for or to purchase, or any warrants or options for the purchase of, 
Common Stock or any stock or securities convertible into or exchangeable for 
Common Stock (any such rights, warrants, or options being herein called 
"Options" and any such convertible or exchangeable stock or securities being 
herein called "Convertible Securities"), other than pursuant to its 1994 Stock 
Option Plan and its 1994 Board Retainer Plan, whether or not such Options or 
the rights to convert or exchange such Convertible Securities are immediately 
exercisable, and the price per share at which Common Stock is issuable upon 
the exercise of such Options or upon the conversion or exchange of such 
Convertible Securities (determined by dividing (i) the aggregate amount, if 
any, received or receivable by the Company as consideration for the issuance, 
sale, distribution, or granting of such Options, plus the minimum aggregate 
amount of additional consideration, if any, payable to the Company upon the 
exercise of all such Options, plus, in the cases of Options to acquire 
Convertible Securities, the minimum aggregate amount of additional 
consideration, if any, payable upon the conversion or exchange of all such 
Convertible Securities, by (ii) the total maximum number of shares of Common 
Stock issuable upon the exercise of all such Options or upon the conversion or 
exchange of all such Options or upon the conversion or exchange of all 
Convertible Securities issuable upon the exercise of all such Options) shall 
be less than the current market price per share of Common Stock on the date of 
the issuance, sale, distribution, or granting of such Options then, for 
purposes of paragraph (b) above, the total maximum number of shares of Common 
Stock issuable upon the exercise of all such Options or upon the conversion or 
exchange of the total maximum amount of the Convertible Securities issuable 
upon the exercise of all such Options) shall be less than the current market 
price per share of Common Stock on the date of the issuance, sale, 
distribution, or granting of such Options shall be deemed to have been issued 
as on the date of the issuance, sale, distribution, or granting of such 
Options and thereafter shall be deemed to be outstanding and the Company shall 
be deemed to have received as consideration such price per share, determined 
as provided above, therefor.  Except as otherwise provided in paragraphs (j) 
and (k) below, no additional adjustment of the Exercise Price shall be made 
upon the actual exercise of such Options or upon conversion or exchange of the 
Convertible Securities issuable upon the exercise of such Options.

          (d)     Issuance of Convertible Securities.  In the event the 
Company shall, at any time or from time to time after the date hereof, issue, 
sell, or otherwise distribute (including by assumption) any Convertible 
Securities (other than upon the exercise of any Option), whether or not the 
rights to convert or exchange such Convertible Securities are immediately 
exercisable, and the price per share at which Common Stock is issuable upon 
the conversion or exchange of such Convertible Securities (determined by 
dividing (i) the aggregate amount, if any, received or receivable by the 
Company as consideration for the issuance, sale, or distribution of such 
Convertible Securities, plus the minimum aggregate amount of additional 
consideration, if any, payable to the Company upon the conversion or exchange 
of all such Convertible Securities, by (ii) the total maximum number of shares 
of Common Stock issuable upon the conversion or exchange of all such 
Convertible Securities) shall be less than the current market price per share 
of Common Stock on the date of such issuance, sale, or distribution, then, for 
purposes of paragraph (b) above, the total maximum number of shares of Common 
Stock issuable upon the conversion or exchange of all such Convertible 
Securities shall be deemed to have been issued as of the date of the issuance, 
sale, or distribution of such Convertible Securities and thereafter shall be 
deemed to be outstanding and the Company shall be deemed to have received as 
consideration such price per share, determined as provided above, therefor.  
Except as otherwise provided in paragraphs (j) and (k) below, no additional 
adjustment of the Exercise Price shall be made upon the actual conversion or 
exchange of such Convertible Securities.

          (e)     Dividends and Distributions.  In the event the Company 
shall, at any time or from time to time after the date hereof, distribute to 
the holders of Common Stock any dividend or other distribution of cash, 
evidences of its indebtedness, other securities, or other properties or assets 
(in each case other than (i) dividends payable in Common Stock, Options, or 
Convertible Securities and (ii) any cash dividend that, when added to all 
other cash dividends paid in the one year prior to the declaration date of 
such dividend (excluding any such other dividend included in a previous 
adjustment of the Exercise Price pursuant to this paragraph (e)), does not 
exceed 10% of the current market price per share of Common Stock on such 
declaration date), or any options, warrants, or other rights to subscribe for 
or purchase any of the foregoing, then (A) the Exercise Price shall be 
decreased to a price determined by multiplying  the Exercise Price then in 
effect by a fraction, the numerator of which shall be the current market price 
per share of Common Stock on the record date for such distribution less the 
sum of (X) the cash portion, if any, of such distribution per share of Common 
Stock outstanding (exclusive of any treasury shares) on the record date for 
such distribution plus (Y) the then fair market value (as determined in good 
faith by the Board of Directors of the Company) per share of Common Stock 
outstanding (exclusive of any treasury shares) on the record date for such 
distribution of that portion, if any, of such distribution consisting of 
evidences of indebtedness, other securities, properties, assets, options, 
warrants, or subscription or purchase rights, and the denominator of which 
shall be such current market price per share of Common Stock and (B) the 
number of shares of Common Stock purchasable upon the exercise of this Warrant 
shall be increased to a number determined by multiplying the number of shares 
of Common Stock so purchasable immediately prior to the record date for such 
distribution by a fraction, the numerator of which shall be the Exercise Price 
in effect immediately prior to the adjustment required by clause (A) of this 
sentence and the denominator of which shall be the Exercise Price in effect 
immediately after such adjustment.  The adjustments required by this paragraph 
(e) shall be made retroactive to the record date for the determination of 
stockholders entitled to receive such distribution.

          (f)     Current Market Price.  For the purpose of any computation 
under paragraphs (b), (c), (d), and (e) of this Section 3.01, the current 
market price per share of Common Stock at any date shall be determined as 
follows:  until the Company has raised an aggregate of $2,000,000 in sales of 
its securities, small business innovation research awards, small business 
technology transfer awards, or payments by corporate partners for research 
support or co-development (it being understood that at the date of this 
Warrant Agreement, the Company has already raised a total of $442,806, 
exclusive of deferred salaries), then the current market price per share 
(prior to any adjustment resulting from a Common Stock Distribution) shall be 
$2.00 per share; thereafter, the current market price per share of the Common 
Stock at any date shall be the average of the daily closing prices for the 
shorter of (i) the 20 consecutive trading days ending on the last full trading 
day on the exchange or market specified in the second succeeding sentence 
prior to the Time of Determination and (ii) the period commencing on the date 
next succeeding the first public announcement of the issuance, sale, 
distribution, or granting in question through such last full trading day prior 
to the Time of Determination.  The term "Time of Determination" as used herein 
shall be the time and date of the earlier to occur of (A) the date as of which 
the current market price is to be computed and (B) the last full trading day 
on such exchange or market before the commencement of "ex-dividend" trading in 
the Common Stock relating to the event giving rise to the adjustment required 
by paragraph (b), (c), (d), or (e).  The closing price for any day shall be 
the last reported sale price regular way or, in case no such reported sale 
takes place on such day, the average of the closing bid and asked prices 
regular way for such day, in each case (1) on the principal national 
securities exchange on which the shares of Common Stock are listed or to which 
such shares are admitted to trading or (2) if the Common Stock is not listed 
or admitted to trading on a national securities exchange, in the over-the-
counter market as reported by NASDAQ or any comparable system or (3) if the 
Common Stock is not listed on NASDAQ or a comparable system, as furnished by 
two members of the National Association of Securities Dealers, Inc. selected 
from time to time in good faith by the Board of Directors of the Company for 
that purpose.  In the absence of all of the foregoing or if for any other 
reason the current market price per share cannot be determined pursuant to the 
foregoing  provisions of this paragraph (f), the current market price per 
share shall be the fair market value thereof as determined in good faith by 
the Board of Directors of the Company.

          (g)     Certain Distributions.  If the Company shall pay a dividend 
or make any other distribution payable in Options or Convertible Securities, 
then, for purposes of paragraph (b) above (by operation of paragraph (c) or 
(d) above, as the as may be), such Options or Convertible Securities shall be 
deemed to have been issued or sold without consideration.

          (h)     Consideration Received.  If any shares of Common Stock, 
Options or Convertible Securities shall be issued, sold, or distributed for a 
consideration other than cash, the amount of the consideration other than cash 
received by the Company in respect thereof shall be deemed to be the then fair 
market value of such consideration (as determined in good faith by the Board 
of Directors of the Company).  If any Options shall be issued in connection 
with the issuance and sale of other securities of the Company, together 
comprising one integral transaction in which no specific consideration is 
allocated to such Options by the parties thereto, such Options shall be deemed 
to have been issued without consideration, provided, however, that if such 
Options have an exercise price equal to or greater than the current market 
price of the Common Stock on the date of issuance of such Options, then such 
Options shall be deemed to have been issued for consideration equal to such 
exercise price.

          (i)     Deferral of Certain Adjustments.  No adjustment to the 
Exercise Price (including the related adjustment to the number of shares of 
Common Stock purchasable upon the exercise of this Warrant) shall be required 
hereunder unless such adjustment, together with other adjustments carried 
forward as provided below, would result in an increase or decrease of at least 
$.10 in the Exercise Price; provided however, that any adjustments which by 
reason of this paragraph (i) are not required to be made shall be carried 
forward and taken into account in any subsequent adjustment.  No adjustment 
need be made for a change in the par value of the Common Stock.

          (j)     Changes in Options and Convertible Securities.  If the 
exercise price provided for in any Options referred to in paragraph (c) above, 
the additional consideration, if any, payable upon the conversion or exchange 
of any Convertible Securities referred to in paragraph (c) or (d) above, or 
the rate at which any Convertible Securities referred to in paragraph (c) or 
(d) above are convertible into or exchangeable for Common Stock shall change 
at any time (other than under or by reason of provisions designed to protect 
against dilution upon an event which results in a related adjustment pursuant 
to this Article III), the Exercise Price then in effect and the number of 
shares of Common Stock purchasable upon the exercise of this Warrant shall 
forthwith be readjusted (effective only with respect to any exercise of this 
Warrant after such readjustment) to the Exercise Price and number of shares of 
Common Stock so purchasable that would then be in effect had the adjustment 
made upon the issuance, sale, distribution, or granting of such Options or 
Convertible Securities been made based upon such changed purchase price, 
additional consideration, or conversion rate, as the case may be, but only 
with respect to such Options and Convertible Securities as then remain 
outstanding.

          (k)     Expiration of Options and Convertible Securities.  If, at 
any time after any adjustment to the number of shares of Common Stock 
purchasable upon the exercise of this Warrant shall have been made pursuant to 
paragraph (c), (d), or (j) above or this paragraph (k), any Options or 
Convertible Securities shall have expired unexercised, the number of such 
shares so purchasable shall, upon such expiration, be readjusted and shall 
thereafter be such as they would have been had they been originally adjusted 
(or had the original adjustment not been required, as the case may be) as if 
(i) the only shares of Common Stock deemed to have been issued in connection 
with such options or Convertible Securities were the shares of Common Stock, 
if any, actually issued or sold upon the exercise of such Options or 
Convertible Securities and (ii) such shares of Common Stock, if any, were 
issued or sold for the consideration actually received by the Company upon 
such exercise plus the aggregate consideration, if any, actually received by 
the Company for the issuance, sale, distribution, or granting of all such 
Options of Convertible Securities, whether or not exercised; provided, 
however, that no such readjustment shall have the effect of decreasing the 
number of such shares so purchasable by an amount (calculated by adjusting 
such decrease to account for all other adjustments made pursuant to this 
Article III following the date of the original adjustment referred to above) 
in excess of the amount of the adjustment initially made in respect of the 
issuance, sale, distribution, or granting of such Options or Convertible 
Securities.

          (l)     Other Adjustments.  In the event that at any time, as a 
result of an adjustment made pursuant to this Article III, the Warrant Holder 
shall become entitled to receive any securities of the Company other than 
shares of Common Stock, thereafter the number of such other securities so 
receivable upon exercise of this Warrant and the Exercise Price applicable to 
such exercise shall be subject to adjustment from time to time in a manner and 
on terms as nearly equivalent as practicable to the provisions with respect to 
the shares of Common Stock contained in this Article III.

     Section 3.02.  Whenever the number of shares of Common Stock or other 
stock or property issuable upon the exercise of this Warrant is adjusted, as 
herein provided, the Company shall promptly mail to the Warrant Holder notice 
of such adjustment or adjustments and shall deliver to the Warrant Holder a 
certificate of a principal officer of the Company setting forth the number of 
shares of Common Stock or other stock or property issuable upon the exercise 
of this Warrant after such adjustment, setting forth a brief statement of the 
facts requiring such adjustment, and setting forth the computation by which 
such adjustment was made.

     Section 3.03.  If at any time after this Warrant is first issued

          (a)     the Company declares a dividend or other distribution on its 
Common Stock payable other than in cash out of its undistributed net income; 
or
          (b)     the Company authorizes the granting to the holders of its 
Common Stock of rights to subscribe for a purchase any shares of any class of 
its capital stock or any other securities; or

          (c)     there is any reclassification of the Common Stock (other 
than a subdivision or combination of its outstanding Common Stock), or any 
consolidation or merger to which the Company is a party and for which approval 
of the holders of the Common Stock is required, or a sale or transfer of all 
or substantially all the assets of the Company; or 

          (d)     there is a voluntary or involuntary dissolution, 
liquidation, or winding up of the Company;

then, in each case, the Company will mail to the Warrant Holder at least 15 
Business Days before the applicable record date a notice stating (i) the 
record date for the dividend, distribution, or rights, or, if there will not 
be a record date, the date as of which the holders of record of Common Stock 
who will be entitled to the dividend, distribution, or rights will be 
determined, or (ii) the date on which the reclassification, consolidation, 
merger, sale, transfer, dissolution, liquidation, or winding up is expected to 
become effective, and the date as of which it is expected the holders of 
record of Common Stock who will be entitled to exchange their Common Stock for 
securities or other property as a result of the reclassification, 
consolidation, merger, sale, transfer, dissolution, liquidation, or winding up 
will be determined.  Failure to give any notice or any defect in the notice 
will not affect the validity of the action which should have been the subject 
of the notice.

     Section 3.04.  The form of this Warrant need not be changed because of 
any change in the Warrant Price or in the number of shares of Common Stock 
which may be purchased by exercising this Warrant.  The Company may, however, 
at any time make any change in the form of Warrant this it deems appropriate 
to reflect a change in the Exercise Price or in the number of shares of Common 
Stock which may be purchased by exercising this Warrant (provided the change 
in the form of Warrant does not otherwise affect the substance of the 
Warrant), and any Warrant issued after the form of Warrant is so changed shall 
be in the changed form.

                                  ARTICLE IV

          Other Provisions Relating to Rights of the Warrant Holder

     Section 4.01.  The Warrant Holder will not, as such, be entitled to 
vote, to receive dividends, or to have any other of the rights of a 
shareholder of the Company, except that after this Warrant is exercised in 
accordance with the terms of this Warrant the persons in whose names the 
shares of Common Stock purchased through exercise of 


this Warrant are to be issued will be deemed to become the holders of record 
of those shares of Common Stock for all purposes even if certificates 
representing such shares of Common Stock have not been issued.

     Section 4.02.1 (a)  The Company will at all times reserve and keep 
available for issuance upon exercise of this Warrant the number of authorized 
and unissued shares of Common Stock equal to the maximum number of shares of 
Common Stock the Company may be required to issue upon exercise of this 
warrant at the Exercise Price in effect from time to time.

              (b)     All shares of Common Stock issued on exercise of this 
Warrant will, when they are issued, be validly issued, fully paid, and 
nonassessable.

     Section 4.03.     The Company will not be required to issue any fraction 
of a share upon exercise of this Warrant.  If any fraction of a share of 
Common Stock would, except for the provisions of this Section, be issuable on 
the exercise of any Warrant (or specified portion thereof), the Company shall 
pay an amount in cash calculated by it to equal to the then current market 
value per share multiplied by such fraction computed to the nearest whole 
cent.  The Warrant Holder, by its acceptance of this Warrant, expressly waives 
any and all rights to receive any fraction of a share of Common Stock or a 
stock certificate representing a fraction of a share of Common Stock.     
     Section 4.04.  The Company will maintain a Warrant Register in which the 
name and address of each registered holder of Warrants will be recorded.

     Section 4.05.     Notices or other communications to the Warrant Holder 
will be deemed given by the Company on the third Business Day after the day on 
which they are sent by registered mail, return receipt requested, addressed to 
the Warrant Holder at the Warrant Holder's last known address shown on the 
Warrant Register.

     Section 4.06.      Prior to due presentment for registration of transfer 
of this Warrant, the Company may treat the Warrant Holder as the absolute 
owner of this Warrant for all purposes, including  for the purpose of 
determining the persons entitled to exercise this Warrant, despite any notice 
to the contrary.

                                  ARTICLE V

                             Transfer of Warrants

     Section 5.01.     This Warrant may be sold, transferred, assigned, or 
hypothecated with the written consent of the Company, in whole or in part.  At 
all times, however, neither this Warrant nor the shares of Common Stock or 
other securities issuable upon exercise of this Warrant may be transferred 
except in a transaction which is registered under the Securities Act of 1933, 
as amended (the "Securities Act"), or which is exempt from the registration 
requirements of the Securities Act.

     Section 5.02.     Upon surrender to the Company at its principal office 
of this Warrant with the Form of Assignment (or another instrument of 
assignment) duly executed and accompanied by (i) (A) evidence that any 
transfer tax has been paid or (B) funds sufficient to pay any transfer tax, or 
(C) evidence to the Company's satisfaction that no such tax is due, and (ii) 
evidence reasonably satisfactory to the Company that the proposed assignment 
will not violate Section 5.01, the Company will, without charge, execute and 
deliver a new Warrant registered in the name of the assignee named in the Form 
of Assignment (or other instrument of assignment) and will promptly cancel 
this Warrant.  This Warrant may be divided or combined with other Warrants by 
surrender of this Warrant and any other Warrants with which it is to be 
combined at the principal office of the Company together with a written 
notice, signed by the Warrant Holder, specifying the names and denominations 
in which new Warrants are to be issued.

     Section 5.03.     Upon receipt by the Company of evidence reasonably 
satisfactory to it of the loss, theft, destruction, or mutilation of this 
Warrant, and (in the case of loss, theft, or destruction) of reasonably 
satisfactory indemnification, or (in the case of mutilation) upon surrender of 
this Warrant, the Company will execute and deliver a new Warrant relating to 
the same number of shares of Common Stock as this Warrant and the lost, 
stolen, destroyed, or mutilated Warrant will become void.  Any new Warrant 
executed and delivered in accordance with this Section 5.03 will constitute an 
additional contractual obligation of the Company, and will be valid and 
enforceable whether or not the Warrant which was believed to have been lost, 
stolen, or destroyed is subsequently presented for exercise.

                                  ARTICLE VI

                    Registration Under the Securities Act

     Section 6.01 (a) If, at any time during the period commencing on July 1, 
1995 and ending on June 30, 2001, The Company shall determine or be required 
to register any shares of the Company's Common Stock (whether on behalf of 
itself or any other person) under the Securities Act of 1933 on Forms S-1, S-
2, S-3, SB-1, or SB-2 (or if such forms are rescinded by the Securities and 
Exchange Commission (the "Commission") such forms as replace those forms), 
excluding any registration for the offering and sale of securities of the 
Company to its employees, it will notify the Warrant Holder in order that it 
may request that all or a part of shares of Common Stock issued or issuable 
upon exercise of this Warrant be included in the registration statement.  If 
requested by any Warrant Holder in writing within 20 days after the Company's 
notice, the Company will include the requested number of shares in such 
registration statement.  Any such request shall include the agreement of the 
Warrant Holder requesting the registration to execute and deliver the 
underwriting agreement, if any, to be executed and delivered in connection 
with such registration.  The Company may, however, decline to include all or a 
part of the requested number of shares in a registration statement pursuant to 
this section if it is advised by the investment banking firm managing the 
underwriting that such inclusion would adversely affect the offering of the 
shares to be covered by the proposed registration statement.

          (b)     The Company shall use its best efforts to file such post-
effective amendments to any registration statement described in this Section 6 
as shall be necessary to keep it effective until six months after the 
effective date of the registration statement or the date on which all of the 
shares of the Warrant Holders covered thereunder shall have been sold, 
whichever is earlier.

          (c)     As a condition to the Company's obligation under this 
Article VI to cause a registration statement or amendment to be filed or 
shares to be included in a registration statement, the Warrant Holder shall 
provide such information and execute such documents as may reasonably be 
required in connection with such registration.  In addition, the Company shall 
not be required to include such shares in a registration statement if it shall 
have received opinions of its and the Warrant Holder's counsel to the effect 
that the proposed disposition of such shares may be effected without 
registration under the Act.

          (d)     The expenses of the registration of Warrant Holders' shares 
(other than transfer taxes, underwriting commissions, and fees of Warrant 
Holders' counsel) shall be paid by the Company.

     Section 6.02.     Unless the resale of shares of Common Stock is the 
subject of an effective registration statement under the Securities Act, the 
certificates representing shares of Common Stock issued upon exercise of this 
Warrant may bear the following legend:

"THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN 
REGISTERED UNDER THE SECURITIES ACT OF 1933.   THE SHARES MAY NOT 
BE OFFERED OR SOLD, EXCEPT (i) PURSUANT TO AN EFFECTIVE 
REGISTRATION STATEMENT OR (ii) IN A TRANSACTION WHICH IS EXEMPT 
FROM THE REGISTRATION REQUIREMENTS OF THAT ACT."

                                Other Matters

     Section 7.01.     The provisions of this Warrant will bind, and inure to 
the benefit of, the Company and its successors and assigns and the Warrant 
Holder and its successors and assigns.

     Section 7.02 (a)  Any notice or other communication to the Company 
relating to this Warrant will be deemed given on the day when it is delivered 
or sent by facsimile transmission (with a confirmation copy sent by registered 
mail, return receipt requested), or on the third Business Day after the day on 
which it is sent by registered mail, return receipt requested, to the Company 
at the following address (or such other address as may be specified by the

          (b)     Any notice or other communication to the Warrant Holder will 
be deemed given when and as provided in Section 4.05.

     Section 7.03.     To the extent such documents are required to be sent 
by the Company to the holders of its outstanding Common Stock, the Company 
shall provide the Warrant Holder, within five Business Days after it files 
them with the Commission, copies of its annual report and of the information, 
documents, and other reports which the Company is required to file with the 
Commission pursuant to Section 13 or 15(d) of the Securities Exchange Act of 
1934.

                                  ARTICLE II

                       Duration and Exercise of Warrant

     Section 2.01.     This Warrant may be exercised at any time after 9:00 
a.m., Gainesville, Florida time, on July 1, 1995, and before 5:00 p.m., 
Gainesville, Florida time, on the Expiration Date.  If this Warrant is not 
exercised at or before 5:00 p.m., Gainesville, Florida time, on the Expiration 
Date, it will become void and neither the Warrant Holder nor any other person 
will have any rights under this Warrant.

     Section 2.02.     (a)  To exercise this Warrant in whole or in part, the 
Warrant Holder must surrender this Warrant, with the Subscription Form duly 
executed, to the Company at its principal office accompanied by a certified or 
official bank check payable to the order of the Company in an amount equal to 
the aggregate Exercise Price for the shares of Common Stock as to which this 
Warrant is being exercised.

          (b)     When the Company receives this Warrant with the Subscription 
Form duly executed and accompanied by payment of the aggregate Exercise Price 
for the shares of Common Stock as to which this Warrant is being exercised, 
the Company will promptly issue certificates, registered in the name of the 
Warrant Holder or such other names as are designated by the Warrant Holder, 
representing the total number of shares of Common Stock (and other securities, 
if any) as to which this Warrant is being exercised, in such denominations as 
are requested by the Warrant Holder, and the Company will deliver promptly 
such certificates to the Warrant Holder.

          (c)     If the Warrant Holder exercises this Warrant with respect to 
fewer than all the shares of Common Stock to which it relates, the Company 
will execute a new Warrant for the balance of the shares of Common Stock that 
may be purchased upon exercise of this Warrant and will deliver promptly such 
new Warrant to the Warrant Holder.

          (d)     The Company will pay any taxes that may be payable in 
respect of (i) the issuance of shares of Common Stock or (ii) the issuance of 
a new Warrant if this Warrant is exercised as to fewer than all the shares of 
Common Stock to which it relates.  The Company will not, however, be required 
to pay any transfer tax payable because shares of Common Stock or a new 
Warrant are to be registered in a name other than that of the Warrant Holder, 
and the Company will not be required to issue any shares of Common Stock or to 
issue a new Warrant registered in a name other than that of the Warrant Holder 
until (i) the Company receives either (A) evidence that any applicable 
transfer taxes have  been paid or (B) funds with which to pay those taxes or 
(ii) it has been established to the Company's satisfaction that no such tax is 
due.


                                 ARTICLE III

                        Adjustment of Exercise Price 
                     and Number of Shares of Common Stock

     Section 3.01.     The Exercise Price and the number of shares of Common 
Stock or other securities issuable on exercise of this Warrant are subject to 
adjustment as follows:

          (a)     Changes in Common Stock.  In the event the Company shall, at 
any time or from time to time after the date hereof, (i) issue any shares of 
Common Stock as a stock dividend to the holders of Common Stock, (ii) 
subdivide or combine the outstanding shares of Common Stock into a greater or 
lesser number of shares or (iii) issue any shares of its capital stock in a 
reclassification, or reorganization of the Common Stock (any such issuance, 
subdivision, combination, reclassification, or reorganization being herein 
called a "Change of Shares"), then (A) in the case of (i) or (ii) above, the 
number of shares of Common Stock that may be purchased upon the exercise of 
this Warrant shall be adjusted to the number of shares of Common Stock that 
the Warrant Holder would have owned or have been entitled to receive after the 
happening of such event had this Warrant been exercised immediately prior to 
the record date (or, if there is no record date, the effective date) for such 
event, and the Exercise Price shall be adjusted to the price (calculated to 
the nearest 1,000th of one cent) determined by multiplying the Exercise Price 
immediately prior to such event by a fraction the numerator of which shall be 
the number of shares of Common Stock purchasable with this Warrant immediately 
prior to such event and the denominator of which shall be the number of shares 
purchasable with this Warrant after the adjustment referred to above and (B) 
in the case of (iii) above, paragraph (l) below shall apply.  An adjustment 
made pursuant to clause (A) of this paragraph shall become effective 
retroactively immediately after the record date in the case of a dividend and 
shall become effective immediately after the effective date in other cases.  
Any shares of Common Stock purchasable solely as a result of such adjustment 
shall not be issued prior to the effective date of such event.

          (b)     Common Stock Distribution.  In the event the Company shall, 
at any time or from time to time after the date hereof, issue, sell, or 
otherwise distribute any shares of Common Stock (other than pursuant to a 
Change of Shares or the exercise of any Option, Convertible Security (each as 
defined in paragraph (c) and (d) below), or Warrant (any such event including 
any event described in paragraphs (c) and (d) below), being herein called a 
"Common Stock Distribution") for a consideration per share less than the 
current market price per share of Common Stock (as defined in paragraph (f) 
below) on the date of such Common Stock Distribution, then, effective upon 
such Common Stock Distribution, the Exercise Price shall be reduced to the 
price (calculated to the nearest 1,000th of one cent) determined by 
multiplying the Exercise Price in effect immediately prior to such Common 
Stock Distribution by a fraction, the numerator of which shall be the sum of 
(i) the number of shares of Common Stock outstanding (exclusive of any 
treasury shares) immediately prior to such Common Stock Distribution 
multiplied by the current market price per share of Common Stock on the date 
of such Common Stock Distribution, plus (ii) the consideration, if any, 
received by the Company upon such Common Stock Distribution, and the 
denominator of which shall be the product of (A) the total number of shares of 
Common Stock outstanding (exclusive of any treasury shares) immediately after 
such Common Stock Distribution multiplied by (B) the current market price per 
share of Common Stock on the date of such Common Stock Distribution.

          If any Common Stock Distribution shall require an adjustment of 
the Exercise Price pursuant to the foregoing provisions of this paragraph (b), 
including by operation of paragraph (c) or (d) below, then, effective at the 
time such adjustment is made, the number of shares of Common Stock purchasable 
upon the exercise of this Warrant shall be increased to a number determined by 
multiplying the number of such shares so purchasable immediately prior to such 
Common Stock Distribution by a fraction, the numerator of which shall be the 
Exercise Price in effect immediately prior to such adjustment and the 
denominator of which shall be the Exercise Price in effect immediately after 
such adjustment.  In computing adjustments under this paragraph, fractional 
interests in Common Stock shall be taken into account to the nearest 1,000th 
of a share.

          The provisions of this paragraph (b), including by operation of 
paragraph (c) or (d) below, shall not operate to increase the Exercise Price 
or reduce the number of shares of Common Stock purchasable upon the exercise 
of this Warrant.

          (c)     Issuance of Options.  In the event the Company shall, at any 
time or from time to time after the date hereof, issue, sell, distribute, or 
otherwise grant in any manner (including by assumption) any rights to 
subscribe for or to purchase, or any warrants or options for the purchase of, 
Common Stock or any stock or securities convertible into or exchangeable for 
Common Stock (any such rights, warrants, or options being herein called 
"Options" and any such convertible or exchangeable stock or securities being 
herein called "Convertible Securities"), other than pursuant to its 1994 Stock 
Option Plan and its 1994 Board Retainer Plan, whether or not such Options or 
the rights to convert or exchange such Convertible Securities are immediately 
exercisable, and the price per share at which Common Stock is issuable upon 
the exercise of such Options or upon the conversion or exchange of such 
Convertible Securities (determined by dividing (i) the aggregate amount, if 
any, received or receivable by the Company as consideration for the issuance, 
sale, distribution, or granting of such Options, plus the minimum aggregate 
amount of additional consideration, if any, payable to the Company upon the 
exercise of all such Options, plus, in the cases of Options to acquire 
Convertible Securities, the minimum aggregate amount of additional 
consideration, if any, payable upon the conversion or exchange of all such 
Convertible Securities, by (ii) the total maximum number of shares of Common 
Stock issuable upon the exercise of all such Options or upon the conversion or 
exchange of all such Options or upon the conversion or exchange of all 
Convertible Securities issuable upon the exercise of all such Options) shall 
be less than the current market price per share of Common Stock on the date of 
the issuance, sale, distribution, or granting of such Options then, for 
purposes of paragraph (b) above, the total maximum number of shares of Common 
Stock issuable upon the exercise of all such Options or upon the conversion or 
exchange of the total maximum amount of the Convertible Securities issuable 
upon the exercise of all such Options) shall be less than the current market 
price per share of Common Stock on the date of the issuance, sale, 
distribution, or granting of such Options shall be deemed to have been issued 
as on the date of the issuance, sale, distribution, or granting of such 
Options and thereafter shall be deemed to be outstanding and the Company shall 
be deemed to have received as consideration such price per share, determined 
as provided above, therefor.  Except as otherwise provided in paragraphs (j) 
and (k) below, no additional adjustment of the Exercise Price shall be made 
upon the actual exercise of such Options or upon conversion or exchange of the 
Convertible Securities issuable upon the exercise of such Options.

          (d)     Issuance of Convertible Securities.  In the event the 
Company shall, at any time or from time to time after the date hereof, issue, 
sell, or otherwise distribute (including by assumption) any Convertible 
Securities (other than upon the exercise of any Option), whether or not the 
rights to convert or exchange such Convertible Securities are immediately 
exercisable, and the price per share at which Common Stock is issuable upon 
the conversion or exchange of such Convertible Securities (determined by 
dividing (i) the aggregate amount, if any, received or receivable by the 
Company as consideration for the issuance, sale, or distribution of such 
Convertible Securities, plus the minimum aggregate amount of additional 
consideration, if any, payable to the Company upon the conversion or exchange 
of all such Convertible Securities, by (ii) the total maximum number of shares 
of Common Stock issuable upon the conversion or exchange of all such 
Convertible Securities) shall be less than the current market price per share 
of Common Stock on the date of such issuance, sale, or distribution, then, for 
purposes of paragraph (b) above, the total maximum number of shares of Common 
Stock issuable upon the conversion or exchange of all such Convertible 
Securities shall be deemed to have been issued as of the date of the issuance, 
sale, or distribution of such Convertible Securities and thereafter shall be 
deemed to be outstanding and the Company shall be deemed to have received as 
consideration such price per share, determined as provided above, therefor.  
Except as otherwise provided in paragraphs (j) and (k) below, no additional 
adjustment of the Exercise Price shall be made upon the actual conversion or 
exchange of such Convertible Securities.

          (e)     Dividends and Distributions.  In the event the Company 
shall, at any time or from time to time after the date hereof, distribute to 
the holders of Common Stock any dividend or other distribution of cash, 
evidences of its indebtedness, other securities, or other properties or assets 
(in each case other than (i) dividends payable in Common Stock, Options, or 
Convertible Securities and (ii) any cash dividend that, when added to all 
other cash dividends paid in the one year prior to the declaration date of 
such dividend (excluding any such other dividend included in a previous 
adjustment of the Exercise Price pursuant to this paragraph (e)), does not 
exceed 10% of the current market price per share of Common Stock on such 
declaration date), or any options, warrants, or other rights to subscribe for 
or purchase any of the foregoing, then (A) the Exercise Price shall be 
decreased to a price determined by multiplying  the Exercise Price then in 
effect by a fraction, the numerator of which shall be the current market price 
per share of Common Stock on the record date for such distribution less the 
sum of (X) the cash portion, if any, of such distribution per share of Common 
Stock outstanding (exclusive of any treasury shares) on the record date for 
such distribution plus (Y) the then fair market value (as determined in good 
faith by the Board of Directors of the Company) per share of Common Stock 
outstanding (exclusive of any treasury shares) on the record date for such 
distribution of that portion, if any, of such distribution consisting of 
evidences of indebtedness, other securities, properties, assets, options, 
warrants, or subscription or purchase rights, and the denominator of which 
shall be such current market price per share of Common Stock and (B) the 
number of shares of Common Stock purchasable upon the exercise of this Warrant 
shall be increased to a number determined by multiplying the number of shares 
of Common Stock so purchasable immediately prior to the record date for such 
distribution by a fraction, the numerator of which shall be the Exercise Price 
in effect immediately prior to the adjustment required by clause (A) of this 
sentence and the denominator of which shall be the Exercise Price in effect 
immediately after such adjustment.  The adjustments required by this paragraph 
(e) shall be made retroactive to the record date for the determination of 
stockholders entitled to receive such distribution.

          (f)     Current Market Price.  For the purpose of any computation 
under paragraphs (b), (c), (d), and (e) of this Section 3.01, the current 
market price per share of Common Stock at any date shall be determined as 
follows:  until the Company has raised an aggregate of $2,000,000 in sales of 
its securities, small business innovation research awards, small business 
technology transfer awards, or payments by corporate partners for research 
support or co-development, then the current market price per share (prior to 
any adjustment resulting from a Common Stock Distribution) shall be $2.00 per 
share; thereafter, the current market price per share of the Common Stock at 
any date shall be the average of the daily closing prices for the shorter of 
(i) the 20 consecutive trading days ending on the last full trading day on the 
exchange or market specified in the second succeeding sentence prior to the 
Time of Determination and (ii) the period commencing on the date next 
succeeding the first public announcement of the issuance, sale, distribution, 
or granting in question through such last full trading day prior to the Time 
of Determination.  The term "Time of Determination" as used herein shall be 
the time and date of the earlier to occur of (A) the date as of which the 
current market price is to be computed and (B) the last full trading day on 
such exchange or market before the commencement of "ex-dividend" trading in 
the Common Stock relating to the event giving rise to the adjustment required 
by paragraph (b), (c), (d), or (e).  The closing price for any day shall be 
the last reported sale price regular way or, in case no such reported sale 
takes place on such day, the average of the closing bid and asked prices 
regular way for such day, in each case (1) on the principal national 
securities exchange on which the shares of Common Stock are listed or to which 
such shares are admitted to trading or (2) if the Common Stock is not listed 
or admitted to trading on a national securities exchange, in the over-the-
counter market as reported by NASDAQ or any comparable system or (3) if the 
Common Stock is not listed on NASDAQ or a comparable system, as furnished by 
two members of the National Association of Securities Dealers, Inc. selected 
from time to time in good faith by the Board of Directors of the Company for 
that purpose.  In the absence of all of the foregoing or if for any other 
reason the current market price per share cannot be determined pursuant to the 
foregoing  provisions of this paragraph (f), the current market price per 
share shall be the fair market value thereof as determined in good faith by 
the Board of Directors of the Company.

          (g)     Certain Distributions.  If the Company shall pay a dividend 
or make any other distribution payable in Options or Convertible Securities, 
then, for purposes of paragraph (b) above (by operation of paragraph (c) or 
(d) above, as the as may be), such Options or Convertible Securities shall be 
deemed to have been issued or sold without consideration.

          (h)     Consideration Received.  If any shares of Common Stock, 
Options or Convertible Securities shall be issued, sold, or distributed for a 
consideration other than cash, the amount of the consideration other than cash 
received by the Company in respect thereof shall be deemed to be the then fair 
market value of such consideration (as determined in good faith by the Board 
of Directors of the Company).  If any Options shall be issued in connection 
with the issuance and sale of other securities of the Company, together 
comprising one integral transaction in which no specific consideration is 
allocated to such Options by the parties thereto, such Options shall be deemed 
to have been issued without consideration, provided, however, that if such 
Options have an exercise price equal to or greater than the current market 
price of the Common Stock on the date of issuance of such Options, then such 
Options shall be deemed to have been issued for consideration equal to such 
exercise price.

          (i)     Deferral of Certain Adjustments.  No adjustment to the 
Exercise Price (including the related adjustment to the number of shares of 
Common Stock purchasable upon the exercise of this Warrant) shall be required 
hereunder unless such adjustment, together with other adjustments carried 
forward as provided below, would result in an increase or decrease of at least 
$.10 in the Exercise Price; provided however, that any adjustments which by 
reason of this paragraph (i) are not required to be made shall be carried 
forward and taken into account in any subsequent adjustment.  No adjustment 
need be made for a change in the par value of the Common Stock.

          (j)     Changes in Options and Convertible Securities.  If the 
exercise price provided for in any Options referred to in paragraph (c) above, 
the additional consideration, if any, payable upon the conversion or exchange 
of any Convertible Securities referred to in paragraph (c) or (d) above, or 
the rate at which any Convertible Securities referred to in paragraph (c) or 
(d) above are convertible into or exchangeable for Common Stock shall change 
at any time (other than under or by reason of provisions designed to protect 
against dilution upon an event which results in a related adjustment pursuant 
to this Article III), the Exercise Price then in effect and the number of 
shares of Common Stock purchasable upon the exercise of this Warrant shall 
forthwith be readjusted (effective only with respect to any exercise of this 
Warrant after such readjustment) to the Exercise Price and number of shares of 
Common Stock so purchasable that would then be in effect had the adjustment 
made upon the issuance, sale, distribution, or granting of such Options or 
Convertible Securities been made based upon such changed purchase price, 
additional consideration, or conversion rate, as the case may be, but only 
with respect to such Options and Convertible Securities as then remain 
outstanding.

          (k)     Expiration of Options and Convertible Securities.  If, at 
any time after any adjustment to the number of shares of Common Stock 
purchasable upon the exercise of this Warrant shall have been made pursuant to 
paragraph (c), (d), or (j) above or this paragraph (k), any Options or 
Convertible Securities shall have expired unexercised, the number of such 
shares so purchasable shall, upon such expiration, be readjusted and shall 
thereafter be such as they would have been had they been originally adjusted 
(or had the original adjustment not been required, as the case may be) as if 
(i) the only shares of Common Stock deemed to have been issued in connection 
with such options or Convertible Securities were the shares of Common Stock, 
if any, actually issued or sold upon the exercise of such Options or 
Convertible Securities and (ii) such shares of Common Stock, if any, were 
issued or sold for the consideration actually received by the Company upon 
such exercise plus the aggregate consideration, if any, actually received by 
the Company for the issuance, sale, distribution, or granting of all such 
Options of Convertible Securities, whether or not exercised; provided, 
however, that no such readjustment shall have the effect of decreasing the 
number of such shares so purchasable by an amount (calculated by adjusting 
such decrease to account for all other adjustments made pursuant to this 
Article III following the date of the original adjustment referred to above) 
in excess of the amount of the adjustment initially made in respect of the 
issuance, sale, distribution, or granting of such Options or Convertible 
Securities.

          (l)     Other Adjustments.  In the event that at any time, as a 
result of an adjustment made pursuant to this Article III, the Warrant Holder 
shall become entitled to receive any securities of the Company other than 
shares of Common Stock, thereafter the number of such other securities so 
receivable upon exercise of this Warrant and the Exercise Price applicable to 
such exercise shall be subject to adjustment from time to time in a manner and 
on terms as nearly equivalent as practicable to the provisions with respect to 
the shares of Common Stock contained in this Article III.

     Section 3.02.  Whenever the number of shares of Common Stock or other 
stock or property issuable upon the exercise of this Warrant is adjusted, as 
herein provided, the Company shall promptly mail to the Warrant Holder notice 
of such adjustment or adjustments and shall deliver to the Warrant Holder a 
certificate of a principal officer of the Company setting forth the number of 
shares of Common Stock or other stock or property issuable upon the exercise 
of this Warrant after such adjustment, setting forth a brief statement of the 
facts requiring such adjustment, and setting forth the computation by which 
such adjustment was made.

     Section 3.03.  If at any time after this Warrant is first issued

          (a)     the Company declares a dividend or other distribution on its 
Common Stock payable other than in cash out of its undistributed net income; 
or

          (b)     the Company authorizes the granting to the holders of its 
Common Stock of rights to subscribe for a purchase any shares of any class of 
its capital stock or any other securities; or

          (c)     there is any reclassification of the Common Stock (other 
than a subdivision or combination of its outstanding Common Stock), or any 
consolidation or merger to which the Company is a party and for which approval 
of the holders of the Common Stock is required, or a sale or transfer of all 
or substantially all the assets of the Company; or 

          (d)     there is a voluntary or involuntary dissolution, 
liquidation, or winding up of the Company;

then, in each case, the Company will mail to the Warrant Holder at least 15 
Business Days before the applicable record date a notice stating (i) the 
record date for the dividend, distribution, or rights, or, if there will not 
be a record date, the date as of which the holders of record of Common Stock 
who will be entitled to the dividend, distribution, or rights will be 
determined, or (ii) the date on which the reclassification, consolidation, 
merger, sale, transfer, dissolution, liquidation, or winding up is expected to 
become effective, and the date as of which it is expected the holders of 
record of Common Stock who will be entitled to exchange their Common Stock for 
securities or other property as a result of the reclassification, 
consolidation, merger, sale, transfer, dissolution, liquidation, or winding up 
will be determined.  Failure to give any notice or any defect in the notice 
will not affect the validity of the action which should have been the subject 
of the notice.

     Section 3.04.  The form of this Warrant need not be changed because of 
any change in the Warrant Price or in the number of shares of Common Stock 
which may be purchased by exercising this Warrant.  The Company may, however, 
at any time make any change in the form of Warrant this it deems appropriate 
to reflect a change in the Exercise Price or in the number of shares of Common 
Stock which may be purchased by exercising this Warrant (provided the change 
in the form of Warrant does not otherwise affect the substance of the 
Warrant), and any Warrant issued after the form of Warrant is so changed shall 
be in the changed form.

                                  ARTICLE IV

          Other Provisions Relating to Rights of the Warrant Holder

     Section 4.01.  The Warrant Holder will not, as such, be entitled to 
vote, to receive dividends, or to have any other of the rights of a 
shareholder of the Company, except that after this Warrant is exercised in 
accordance with the terms of this Warrant the persons in whose names the 
shares of Common Stock purchased through exercise of 


this Warrant are to be issued will be deemed to become the holders of record 
of those shares of Common Stock for all purposes even if certificates 
representing such shares of Common Stock have not been issued.

     Section 4.02.1 (a)  The Company will at all times reserve and keep 
available for issuance upon exercise of this Warrant the number of authorized 
and unissued shares of Common Stock equal to the maximum number of shares of 
Common Stock the Company may be required to issue upon exercise of this 
warrant at the Exercise Price in effect from time to time.

              (b)     All shares of Common Stock issued on exercise of this 
Warrant will, when they are issued, be validly issued, fully paid, and 
nonassessable.

     Section 4.03.     The Company will not be required to issue any fraction 
of a share upon exercise of this Warrant.  If any fraction of a share of 
Common Stock would, except for the provisions of this Section, be issuable on 
the exercise of any Warrant (or specified portion thereof), the Company shall 
pay an amount in cash calculated by it to equal to the then current market 
value per share multiplied by such fraction computed to the nearest whole 
cent.  The Warrant Holder, by its acceptance of this Warrant, expressly waives 
any and all rights to receive any fraction of a share of Common Stock or a 
stock certificate representing a fraction of a share of Common Stock.     
     Section 4.04.  The Company will maintain a Warrant Register in which the 
name and address of each registered holder of Warrants will be recorded.

     Section 4.05.     Notices or other communications to the Warrant Holder 
will be deemed given by the Company on the third Business Day after the day on 
which they are sent by registered mail, return receipt requested, addressed to 
the Warrant Holder at the Warrant Holder's last known address shown on the 
Warrant Register.

     Section 4.06.      Prior to due presentment for registration of transfer 
of this Warrant, the Company may treat the Warrant Holder as the absolute 
owner of this Warrant for all purposes, including  for the purpose of 
determining the persons entitled to exercise this Warrant, despite any notice 
to the contrary.

                                  ARTICLE V

                             Transfer of Warrants

     Section 5.01.     This Warrant may be sold, transferred, assigned, or 
hypothecated with the written consent of the Company, in whole or in part.  At 
all times, however, neither this Warrant nor the shares of Common Stock or 
other securities issuable upon exercise of this Warrant may be transferred 
except in a transaction which is registered under the Securities Act of 1933, 
as amended (the "Securities Act"), or which is exempt from the registration 
requirements of the Securities Act.

     Section 5.02.     Upon surrender to the Company at its principal office 
of this Warrant with the Form of Assignment (or another instrument of 
assignment) duly executed and accompanied by (i) (A) evidence that any 
transfer tax has been paid or (B) funds sufficient to pay any transfer tax, or 
(C) evidence to the Company's satisfaction that no such tax is due, and (ii) 
evidence reasonably satisfactory to the Company that the proposed assignment 
will not violate Section 5.01, the Company will, without charge, execute and 
deliver a new Warrant registered in the name of the assignee named in the Form 
of Assignment (or other instrument of assignment) and will promptly cancel 
this Warrant.  This Warrant may be divided or combined with other Warrants by 
surrender of this Warrant and any other Warrants with which it is to be 
combined at the principal office of the Company together with a written 
notice, signed by the Warrant Holder, specifying the names and denominations 
in which new Warrants are to be issued.

     Section 5.03.     Upon receipt by the Company of evidence reasonably 
satisfactory to it of the loss, theft, destruction, or mutilation of this 
Warrant, and (in the case of loss, theft, or destruction) of reasonably 
satisfactory indemnification, or (in the case of mutilation) upon surrender of 
this Warrant, the Company will execute and deliver a new Warrant relating to 
the same number of shares of Common Stock as this Warrant and the lost, 
stolen, destroyed, or mutilated Warrant will become void.  Any new Warrant 
executed and delivered in accordance with this Section 5.03 will constitute an 
additional contractual obligation of the Company, and will be valid and 
enforceable whether or not the Warrant which was believed to have been lost, 
stolen, or destroyed is subsequently presented for exercise.

                                  ARTICLE VI

                    Registration Under the Securities Act

     Section 6.01 (a) If, at any time during the period commencing on July 1, 
1995 and ending on June 30, 2001, The Company shall determine or be required 
to register any shares of the Company's Common Stock (whether on behalf of 
itself or any other person) under the Securities Act of 1933 on Forms S-1, S-
2, S-3, SB-1, or SB-2 (or if such forms are rescinded by the Securities and 
Exchange Commission (the "Commission") such forms as replace those forms), 
excluding any registration for the offering and sale of securities of the 
Company to its employees, it will notify the Warrant Holder in order that it 
may request that all or a part of shares of Common Stock issued or issuable 
upon exercise of this Warrant be included in the registration statement.  If 
requested by any Warrant Holder in writing within 20 days after the Company's 
notice, the Company will include the requested number of shares in such 
registration statement.  Any such request shall include the agreement of the 
Warrant Holder requesting the registration to execute and deliver the 
underwriting agreement, if any, to be executed and delivered in connection 
with such registration.  The Company may, however, decline to include all or a 
part of the requested number of shares in a registration statement pursuant to 
this section if it is advised by the investment banking firm managing the 
underwriting that such inclusion would adversely affect the offering of the 
shares to be covered by the proposed registration statement.

          (b)     The Company shall use its best efforts to file such post-
effective amendments to any registration statement described in this Section 6 
as shall be necessary to keep it effective until six months after the 
effective date of the registration statement or the date on which all of the 
shares of the Warrant Holders covered thereunder shall have been sold, 
whichever is earlier.

          (c)     As a condition to the Company's obligation under this 
Article VI to cause a registration statement or amendment to be filed or 
shares to be included in a registration statement, the Warrant Holder shall 
provide such information and execute such documents as may reasonably be 
required in connection with such registration.  In addition, the Company shall 
not be required to include such shares in a registration statement if it shall 
have received opinions of its and the Warrant Holder's counsel to the effect 
that the proposed disposition of such shares may be effected without 
registration under the Act.

          (d)     The expenses of the registration of Warrant Holders' shares 
(other than transfer taxes, underwriting commissions, and fees of Warrant 
Holders' counsel) shall be paid by the Company.

     Section 6.02.     Unless the resale of shares of Common Stock is the 
subject of an effective registration statement under the Securities Act, the 
certificates representing shares of Common Stock issued upon exercise of this 
Warrant may bear the following legend:

"THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN 
REGISTERED UNDER THE SECURITIES ACT OF 1933.   THE SHARES MAY NOT 
BE OFFERED OR SOLD, EXCEPT (i) PURSUANT TO AN EFFECTIVE 
REGISTRATION STATEMENT OR (ii) IN A TRANSACTION WHICH IS EXEMPT 
FROM THE REGISTRATION REQUIREMENTS OF THAT ACT."

                                 ARTICLE VII
                                Other Matters

     Section 7.01.     The provisions of this Warrant will bind, and inure to 
the benefit of, the Company and its successors and assigns and the Warrant 
Holder and its successors and assigns.

     Section 7.02 (a)  Any notice or other communication to the Company 
relating to this Warrant will be deemed given on the day when it is delivered 
or sent by facsimile transmission (with a confirmation copy sent by registered 
mail, return receipt requested), or on the third Business Day after the day on 
which it is sent by registered mail, return receipt requested, to the Company 
at the following address (or such other address as may be specified by the 
Company after the date of this Warrant):

                 Executive Officer
          Facsimile No.  (904) 462-0875

          (b)     Any notice or other communication to the Warrant Holder will 
be deemed given when and as provided in Section 4.05.

     Section 7.03.     To the extent such documents are required to be sent 
by the Company to the holders of its outstanding Common Stock, the Company 
shall provide the Warrant Holder, within five Business Days after it files 
them with the Commission, copies of its annual report and of the information, 
documents, and other reports which the Company is required to file with the 
Commission pursuant to Section 13 or 15(d) of the Securities Exchange Act of 
1934.

     Section 7.04.     THIS WARRANT WILL BE GOVERNED BY, AND CONSTRUED UNDER, 
THE LAWS OF THE STATE OF FLORIDA RELATING TO CONTRACTS AND INSTRUMENTS 
EXECUTED AND TO BE PERFORMED ENTIRELY IN SUCH STATE.

                                  ARTICLE II

                       Duration and Exercise of Warrant

     Section 2.01.     This Warrant may be exercised at any time after 9:00 
a.m., Gainesville, Florida time, on July 1, 1995, and before 5:00 p.m., 
Gainesville, Florida time, on the Expiration Date.  If this Warrant is not 
exercised at or before 5:00 p.m., Gainesville, Florida time, on the Expiration 
Date, it will become void and neither the Warrant Holder nor any other person 
will have any rights under this Warrant.

     Section 2.02.     (a)  To exercise this Warrant in whole or in part, the 
Warrant Holder must surrender this Warrant, with the Subscription Form duly 
executed, to the Company at its principal office accompanied by a certified or 
official bank check payable to the order of the Company in an amount equal to 
the aggregate Exercise Price for the shares of Common Stock as to which this 
Warrant is being exercised.

          (b)     When the Company receives this Warrant with the Subscription 
Form duly executed and accompanied by payment of the aggregate Exercise Price 
for the shares of Common Stock as to which this Warrant is being exercised, 
the Company will promptly issue certificates, registered in the name of the 
Warrant Holder or such other names as are designated by the Warrant Holder, 
representing the total number of shares of Common Stock (and other securities, 
if any) as to which this Warrant is being exercised, in such denominations as 
are requested by the Warrant Holder, and the Company will deliver promptly 
such certificates to the Warrant Holder.

          (c)     If the Warrant Holder exercises this Warrant with respect to 
fewer than all the shares of Common Stock to which it relates, the Company 
will execute a new Warrant for the balance of the shares of Common Stock that 
may be purchased upon exercise of this Warrant and will deliver promptly such 
new Warrant to the Warrant Holder.

          (d)     The Company will pay any taxes that may be payable in 
respect of (i) the issuance of shares of Common Stock or (ii) the issuance of 
a new Warrant if this Warrant is exercised as to fewer than all the shares of 
Common Stock to which it relates.  The Company will not, however, be required 
to pay any transfer tax payable because shares of Common Stock or a new 
Warrant are to be registered in a name other than that of the Warrant Holder, 
and the Company will not be required to issue any shares of Common Stock or to 
issue a new Warrant registered in a name other than that of the Warrant Holder 
until (i) the Company receives either (A) evidence that any applicable 
transfer taxes have  been paid or (B) funds with which to pay those taxes or 
(ii) it has been established to the Company's satisfaction that no such tax is 
due.


                                 ARTICLE III

                        Adjustment of Exercise Price 
                     and Number of Shares of Common Stock

     Section 3.01.     The Exercise Price and the number of shares of Common 
Stock or other securities issuable on exercise of this Warrant are subject to 
adjustment as follows:

          (a)     Changes in Common Stock.  In the event the Company shall, at 
any time or from time to time after the date hereof, (i) issue any shares of 
Common Stock as a stock dividend to the holders of Common Stock, (ii) 
subdivide or combine the outstanding shares of Common Stock into a greater or 
lesser number of shares or (iii) issue any shares of its capital stock in a 
reclassification, or reorganization of the Common Stock (any such issuance, 
subdivision, combination, reclassification, or reorganization being herein 
called a "Change of Shares"), then (A) in the case of (i) or (ii) above, the 
number of shares of Common Stock that may be purchased upon the exercise of 
this Warrant shall be adjusted to the number of shares of Common Stock that 
the Warrant Holder would have owned or have been entitled to receive after the 
happening of such event had this Warrant been exercised immediately prior to 
the record date (or, if there is no record date, the effective date) for such 
event, and the Exercise Price shall be adjusted to the price (calculated to 
the nearest 1,000th of one cent) determined by multiplying the Exercise Price 
immediately prior to such event by a fraction the numerator of which shall be 
the number of shares of Common Stock purchasable with this Warrant immediately 
prior to such event and the denominator of which shall be the number of shares 
purchasable with this Warrant after the adjustment referred to above and (B) 
in the case of (iii) above, paragraph (l) below shall apply.  An adjustment 
made pursuant to clause (A) of this paragraph shall become effective 
retroactively immediately after the record date in the case of a dividend and 
shall become effective immediately after the effective date in other cases.  
Any shares of Common Stock purchasable solely as a result of such adjustment 
shall not be issued prior to the effective date of such event.

          (b)     Common Stock Distribution.  In the event the Company shall, 
at any time or from time to time after the date hereof, issue, sell, or 
otherwise distribute any shares of Common Stock (other than pursuant to a 
Change of Shares or the exercise of any Option, Convertible Security (each as 
defined in paragraph (c) and (d) below), or Warrant (any such event including 
any event described in paragraphs (c) and (d) below), being herein called a 
"Common Stock Distribution") for a consideration per share less than the 
current market price per share of Common Stock (as defined in paragraph (f) 
below) on the date of such Common Stock Distribution, then, effective upon 
such Common Stock Distribution, the Exercise Price shall be reduced to the 
price (calculated to the nearest 1,000th of one cent) determined by 
multiplying the Exercise Price in effect immediately prior to such Common 
Stock Distribution by a fraction, the numerator of which shall be the sum of 
(i) the number of shares of Common Stock outstanding (exclusive of any 
treasury shares) immediately prior to such Common Stock Distribution 
multiplied by the current market price per share of Common Stock on the date 
of such Common Stock Distribution, plus (ii) the consideration, if any, 
received by the Company upon such Common Stock Distribution, and the 
denominator of which shall be the product of (A) the total number of shares of 
Common Stock outstanding (exclusive of any treasury shares) immediately after 
such Common Stock Distribution multiplied by (B) the current market price per 
share of Common Stock on the date of such Common Stock Distribution.

          If any Common Stock Distribution shall require an adjustment of 
the Exercise Price pursuant to the foregoing provisions of this paragraph (b), 
including by operation of paragraph (c) or (d) below, then, effective at the 
time such adjustment is made, the number of shares of Common Stock purchasable 
upon the exercise of this Warrant shall be increased to a number determined by 
multiplying the number of such shares so purchasable immediately prior to such 
Common Stock Distribution by a fraction, the numerator of which shall be the 
Exercise Price in effect immediately prior to such adjustment and the 
denominator of which shall be the Exercise Price in effect immediately after 
such adjustment.  In computing adjustments under this paragraph, fractional 
interests in Common Stock shall be taken into account to the nearest 1,000th 
of a share.

          The provisions of this paragraph (b), including by operation of 
paragraph (c) or (d) below, shall not operate to increase the Exercise Price 
or reduce the number of shares of Common Stock purchasable upon the exercise 
of this Warrant.

          (c)     Issuance of Options.  In the event the Company shall, at any 
time or from time to time after the date hereof, issue, sell, distribute, or 
otherwise grant in any manner (including by assumption) any rights to 
subscribe for or to purchase, or any warrants or options for the purchase of, 
Common Stock or any stock or securities convertible into or exchangeable for 
Common Stock (any such rights, warrants, or options being herein called 
"Options" and any such convertible or exchangeable stock or securities being 
herein called "Convertible Securities"), other than pursuant to its 1994 Stock 
Option Plan and its 1994 Board Retainer Plan, whether or not such Options or 
the rights to convert or exchange such Convertible Securities are immediately 
exercisable, and the price per share at which Common Stock is issuable upon 
the exercise of such Options or upon the conversion or exchange of such 
Convertible Securities (determined by dividing (i) the aggregate amount, if 
any, received or receivable by the Company as consideration for the issuance, 
sale, distribution, or granting of such Options, plus the minimum aggregate 
amount of additional consideration, if any, payable to the Company upon the 
exercise of all such Options, plus, in the cases of Options to acquire 
Convertible Securities, the minimum aggregate amount of additional 
consideration, if any, payable upon the conversion or exchange of all such 
Convertible Securities, by (ii) the total maximum number of shares of Common 
Stock issuable upon the exercise of all such Options or upon the conversion or 
exchange of all such Options or upon the conversion or exchange of all 
Convertible Securities issuable upon the exercise of all such Options) shall 
be less than the current market price per share of Common Stock on the date of 
the issuance, sale, distribution, or granting of such Options then, for 
purposes of paragraph (b) above, the total maximum number of shares of Common 
Stock issuable upon the exercise of all such Options or upon the conversion or 
exchange of the total maximum amount of the Convertible Securities issuable 
upon the exercise of all such Options) shall be less than the current market 
price per share of Common Stock on the date of the issuance, sale, 
distribution, or granting of such Options shall be deemed to have been issued 
as on the date of the issuance, sale, distribution, or granting of such 
Options and thereafter shall be deemed to be outstanding and the Company shall 
be deemed to have received as consideration such price per share, determined 
as provided above, therefor.  Except as otherwise provided in paragraphs (j) 
and (k) below, no additional adjustment of the Exercise Price shall be made 
upon the actual exercise of such Options or upon conversion or exchange of the 
Convertible Securities issuable upon the exercise of such Options.

          (d)     Issuance of Convertible Securities.  In the event the 
Company shall, at any time or from time to time after the date hereof, issue, 
sell, or otherwise distribute (including by assumption) any Convertible 
Securities (other than upon the exercise of any Option), whether or not the 
rights to convert or exchange such Convertible Securities are immediately 
exercisable, and the price per share at which Common Stock is issuable upon 
the conversion or exchange of such Convertible Securities (determined by 
dividing (i) the aggregate amount, if any, received or receivable by the 
Company as consideration for the issuance, sale, or distribution of such 
Convertible Securities, plus the minimum aggregate amount of additional 
consideration, if any, payable to the Company upon the conversion or exchange 
of all such Convertible Securities, by (ii) the total maximum number of shares 
of Common Stock issuable upon the conversion or exchange of all such 
Convertible Securities) shall be less than the current market price per share 
of Common Stock on the date of such issuance, sale, or distribution, then, for 
purposes of paragraph (b) above, the total maximum number of shares of Common 
Stock issuable upon the conversion or exchange of all such Convertible 
Securities shall be deemed to have been issued as of the date of the issuance, 
sale, or distribution of such Convertible Securities and thereafter shall be 
deemed to be outstanding and the Company shall be deemed to have received as 
consideration such price per share, determined as provided above, therefor.  
Except as otherwise provided in paragraphs (j) and (k) below, no additional 
adjustment of the Exercise Price shall be made upon the actual conversion or 
exchange of such Convertible Securities.

          (e)     Dividends and Distributions.  In the event the Company 
shall, at any time or from time to time after the date hereof, distribute to 
the holders of Common Stock any dividend or other distribution of cash, 
evidences of its indebtedness, other securities, or other properties or assets 
(in each case other than (i) dividends payable in Common Stock, Options, or 
Convertible Securities and (ii) any cash dividend that, when added to all 
other cash dividends paid in the one year prior to the declaration date of 
such dividend (excluding any such other dividend included in a previous 
adjustment of the Exercise Price pursuant to this paragraph (e)), does not 
exceed 10% of the current market price per share of Common Stock on such 
declaration date), or any options, warrants, or other rights to subscribe for 
or purchase any of the foregoing, then (A) the Exercise Price shall be 
decreased to a price determined by multiplying  the Exercise Price then in 
effect by a fraction, the numerator of which shall be the current market price 
per share of Common Stock on the record date for such distribution less the 
sum of (X) the cash portion, if any, of such distribution per share of Common 
Stock outstanding (exclusive of any treasury shares) on the record date for 
such distribution plus (Y) the then fair market value (as determined in good 
faith by the Board of Directors of the Company) per share of Common Stock 
outstanding (exclusive of any treasury shares) on the record date for such 
distribution of that portion, if any, of such distribution consisting of 
evidences of indebtedness, other securities, properties, assets, options, 
warrants, or subscription or purchase rights, and the denominator of which 
shall be such current market price per share of Common Stock and (B) the 
number of shares of Common Stock purchasable upon the exercise of this Warrant 
shall be increased to a number determined by multiplying the number of shares 
of Common Stock so purchasable immediately prior to the record date for such 
distribution by a fraction, the numerator of which shall be the Exercise Price 
in effect immediately prior to the adjustment required by clause (A) of this 
sentence and the denominator of which shall be the Exercise Price in effect 
immediately after such adjustment.  The adjustments required by this paragraph 
(e) shall be made retroactive to the record date for the determination of 
stockholders entitled to receive such distribution.

          (f)     Current Market Price.  For the purpose of any computation 
under paragraphs (b), (c), (d), and (e) of this Section 3.01, the current 
market price per share of Common Stock at any date shall be determined as 
follows:  until the Company has raised an aggregate of $2,000,000 in sales of 
its securities, small business innovation research awards, small business 
technology transfer awards, or payments by corporate partners for research 
support or co-development, then the current market price per share (prior to 
any adjustment resulting from a Common Stock Distribution) shall be $2.00 per 
share; thereafter, the current market price per share of the Common Stock at 
any date shall be the average of the daily closing prices for the shorter of 
(i) the 20 consecutive trading days ending on the last full trading day on the 
exchange or market specified in the second succeeding sentence prior to the 
Time of Determination and (ii) the period commencing on the date next 
succeeding the first public announcement of the issuance, sale, distribution, 
or granting in question through such last full trading day prior to the Time 
of Determination.  The term "Time of Determination" as used herein shall be 
the time and date of the earlier to occur of (A) the date as of which the 
current market price is to be computed and (B) the last full trading day on 
such exchange or market before the commencement of "ex-dividend" trading in 
the Common Stock relating to the event giving rise to the adjustment required 
by paragraph (b), (c), (d), or (e).  The closing price for any day shall be 
the last reported sale price regular way or, in case no such reported sale 
takes place on such day, the average of the closing bid and asked prices 
regular way for such day, in each case (1) on the principal national 
securities exchange on which the shares of Common Stock are listed or to which 
such shares are admitted to trading or (2) if the Common Stock is not listed 
or admitted to trading on a national securities exchange, in the over-the-
counter market as reported by NASDAQ or any comparable system or (3) if the 
Common Stock is not listed on NASDAQ or a comparable system, as furnished by 
two members of the National Association of Securities Dealers, Inc. selected 
from time to time in good faith by the Board of Directors of the Company for 
that purpose.  In the absence of all of the foregoing or if for any other 
reason the current market price per share cannot be determined pursuant to the 
foregoing  provisions of this paragraph (f), the current market price per 
share shall be the fair market value thereof as determined in good faith by 
the Board of Directors of the Company.

          (g)     Certain Distributions.  If the Company shall pay a dividend 
or make any other distribution payable in Options or Convertible Securities, 
then, for purposes of paragraph (b) above (by operation of paragraph (c) or 
(d) above, as the as may be), such Options or Convertible Securities shall be 
deemed to have been issued or sold without consideration.

          (h)     Consideration Received.  If any shares of Common Stock, 
Options or Convertible Securities shall be issued, sold, or distributed for a 
consideration other than cash, the amount of the consideration other than cash 
received by the Company in respect thereof shall be deemed to be the then fair 
market value of such consideration (as determined in good faith by the Board 
of Directors of the Company).  If any Options shall be issued in connection 
with the issuance and sale of other securities of the Company, together 
comprising one integral transaction in which no specific consideration is 
allocated to such Options by the parties thereto, such Options shall be deemed 
to have been issued without consideration, provided, however, that if such 
Options have an exercise price equal to or greater than the current market 
price of the Common Stock on the date of issuance of such Options, then such 
Options shall be deemed to have been issued for consideration equal to such 
exercise price.

          (i)     Deferral of Certain Adjustments.  No adjustment to the 
Exercise Price (including the related adjustment to the number of shares of 
Common Stock purchasable upon the exercise of this Warrant) shall be required 
hereunder unless such adjustment, together with other adjustments carried 
forward as provided below, would result in an increase or decrease of at least 
$.10 in the Exercise Price; provided however, that any adjustments which by 
reason of this paragraph (i) are not required to be made shall be carried 
forward and taken into account in any subsequent adjustment.  No adjustment 
need be made for a change in the par value of the Common Stock.

          (j)     Changes in Options and Convertible Securities.  If the 
exercise price provided for in any Options referred to in paragraph (c) above, 
the additional consideration, if any, payable upon the conversion or exchange 
of any Convertible Securities referred to in paragraph (c) or (d) above, or 
the rate at which any Convertible Securities referred to in paragraph (c) or 
(d) above are convertible into or exchangeable for Common Stock shall change 
at any time (other than under or by reason of provisions designed to protect 
against dilution upon an event which results in a related adjustment pursuant 
to this Article III), the Exercise Price then in effect and the number of 
shares of Common Stock purchasable upon the exercise of this Warrant shall 
forthwith be readjusted (effective only with respect to any exercise of this 
Warrant after such readjustment) to the Exercise Price and number of shares of 
Common Stock so purchasable that would then be in effect had the adjustment 
made upon the issuance, sale, distribution, or granting of such Options or 
Convertible Securities been made based upon such changed purchase price, 
additional consideration, or conversion rate, as the case may be, but only 
with respect to such Options and Convertible Securities as then remain 
outstanding.

          (k)     Expiration of Options and Convertible Securities.  If, at 
any time after any adjustment to the number of shares of Common Stock 
purchasable upon the exercise of this Warrant shall have been made pursuant to 
paragraph (c), (d), or (j) above or this paragraph (k), any Options or 
Convertible Securities shall have expired unexercised, the number of such 
shares so purchasable shall, upon such expiration, be readjusted and shall 
thereafter be such as they would have been had they been originally adjusted 
(or had the original adjustment not been required, as the case may be) as if 
(i) the only shares of Common Stock deemed to have been issued in connection 
with such options or Convertible Securities were the shares of Common Stock, 
if any, actually issued or sold upon the exercise of such Options or 
Convertible Securities and (ii) such shares of Common Stock, if any, were 
issued or sold for the consideration actually received by the Company upon 
such exercise plus the aggregate consideration, if any, actually received by 
the Company for the issuance, sale, distribution, or granting of all such 
Options of Convertible Securities, whether or not exercised; provided, 
however, that no such readjustment shall have the effect of decreasing the 
number of such shares so purchasable by an amount (calculated by adjusting 
such decrease to account for all other adjustments made pursuant to this 
Article III following the date of the original adjustment referred to above) 
in excess of the amount of the adjustment initially made in respect of the 
issuance, sale, distribution, or granting of such Options or Convertible 
Securities.

          (l)     Other Adjustments.  In the event that at any time, as a 
result of an adjustment made pursuant to this Article III, the Warrant Holder 
shall become entitled to receive any securities of the Company other than 
shares of Common Stock, thereafter the number of such other securities so 
receivable upon exercise of this Warrant and the Exercise Price applicable to 
such exercise shall be subject to adjustment from time to time in a manner and 
on terms as nearly equivalent as practicable to the provisions with respect to 
the shares of Common Stock contained in this Article III.

     Section 3.02.  Whenever the number of shares of Common Stock or other 
stock or property issuable upon the exercise of this Warrant is adjusted, as 
herein provided, the Company shall promptly mail to the Warrant Holder notice 
of such adjustment or adjustments and shall deliver to the Warrant Holder a 
certificate of a principal officer of the Company setting forth the number of 
shares of Common Stock or other stock or property issuable upon the exercise 
of this Warrant after such adjustment, setting forth a brief statement of the 
facts requiring such adjustment, and setting forth the computation by which 
such adjustment was made.

     Section 3.03.  If at any time after this Warrant is first issued

          (a)     the Company declares a dividend or other distribution on its 
Common Stock payable other than in cash out of its undistributed net income; 
or

          (b)     the Company authorizes the granting to the holders of its 
Common Stock of rights to subscribe for a purchase any shares of any class of 
its capital stock or any other securities; or

          (c)     there is any reclassification of the Common Stock (other 
than a subdivision or combination of its outstanding Common Stock), or any 
consolidation or merger to which the Company is a party and for which approval 
of the holders of the Common Stock is required, or a sale or transfer of all 
or substantially all the assets of the Company; or 

          (d)     there is a voluntary or involuntary dissolution, 
liquidation, or winding up of the Company;

then, in each case, the Company will mail to the Warrant Holder at least 15 
Business Days before the applicable record date a notice stating (i) the 
record date for the dividend, distribution, or rights, or, if there will not 
be a record date, the date as of which the holders of record of Common Stock 
who will be entitled to the dividend, distribution, or rights will be 
determined, or (ii) the date on which the reclassification, consolidation, 
merger, sale, transfer, dissolution, liquidation, or winding up is expected to 
become effective, and the date as of which it is expected the holders of 
record of Common Stock who will be entitled to exchange their Common Stock for 
securities or other property as a result of the reclassification, 
consolidation, merger, sale, transfer, dissolution, liquidation, or winding up 
will be determined.  Failure to give any notice or any defect in the notice 
will not affect the validity of the action which should have been the subject 
of the notice.

     Section 3.04.  The form of this Warrant need not be changed because of 
any change in the Warrant Price or in the number of shares of Common Stock 
which may be purchased by exercising this Warrant.  The Company may, however, 
at any time make any change in the form of Warrant this it deems appropriate 
to reflect a change in the Exercise Price or in the number of shares of Common 
Stock which may be purchased by exercising this Warrant (provided the change 
in the form of Warrant does not otherwise affect the substance of the 
Warrant), and any Warrant issued after the form of Warrant is so changed shall 
be in the changed form.

                                  ARTICLE IV

          Other Provisions Relating to Rights of the Warrant Holder

     Section 4.01.  The Warrant Holder will not, as such, be entitled to 
vote, to receive dividends, or to have any other of the rights of a 
shareholder of the Company, except that after this Warrant is exercised in 
accordance with the terms of this Warrant the persons in whose names the 
shares of Common Stock purchased through exercise of 


this Warrant are to be issued will be deemed to become the holders of record 
of those shares of Common Stock for all purposes even if certificates 
representing such shares of Common Stock have not been issued.

     Section 4.02.1 (a)  The Company will at all times reserve and keep 
available for issuance upon exercise of this Warrant the number of authorized 
and unissued shares of Common Stock equal to the maximum number of shares of 
Common Stock the Company may be required to issue upon exercise of this 
warrant at the Exercise Price in effect from time to time.

              (b)     All shares of Common Stock issued on exercise of this 
Warrant will, when they are issued, be validly issued, fully paid, and 
nonassessable.

     Section 4.03.     The Company will not be required to issue any fraction 
of a share upon exercise of this Warrant.  If any fraction of a share of 
Common Stock would, except for the provisions of this Section, be issuable on 
the exercise of any Warrant (or specified portion thereof), the Company shall 
pay an amount in cash calculated by it to equal to the then current market 
value per share multiplied by such fraction computed to the nearest whole 
cent.  The Warrant Holder, by its acceptance of this Warrant, expressly waives 
any and all rights to receive any fraction of a share of Common Stock or a 
stock certificate representing a fraction of a share of Common Stock.     
     Section 4.04.  The Company will maintain a Warrant Register in which the 
name and address of each registered holder of Warrants will be recorded.

     Section 4.05.     Notices or other communications to the Warrant Holder 
will be deemed given by the Company on the third Business Day after the day on 
which they are sent by registered mail, return receipt requested, addressed to 
the Warrant Holder at the Warrant Holder's last known address shown on the 
Warrant Register.

     Section 4.06.      Prior to due presentment for registration of transfer 
of this Warrant, the Company may treat the Warrant Holder as the absolute 
owner of this Warrant for all purposes, including  for the purpose of 
determining the persons entitled to exercise this Warrant, despite any notice 
to the contrary.

                                  ARTICLE V

                             Transfer of Warrants

     Section 5.01.     This Warrant may be sold, transferred, assigned, or 
hypothecated with the written consent of the Company, in whole or in part.  At 
all times, however, neither this Warrant nor the shares of Common Stock or 
other securities issuable upon exercise of this Warrant may be transferred 
except in a transaction which is registered under the Securities Act of 1933, 
as amended (the "Securities Act"), or which is exempt from the registration 
requirements of the Securities Act.

     Section 5.02.     Upon surrender to the Company at its principal office 
of this Warrant with the Form of Assignment (or another instrument of 
assignment) duly executed and accompanied by (i) (A) evidence that any 
transfer tax has been paid or (B) funds sufficient to pay any transfer tax, or 
(C) evidence to the Company's satisfaction that no such tax is due, and (ii) 
evidence reasonably satisfactory to the Company that the proposed assignment 
will not violate Section 5.01, the Company will, without charge, execute and 
deliver a new Warrant registered in the name of the assignee named in the Form 
of Assignment (or other instrument of assignment) and will promptly cancel 
this Warrant.  This Warrant may be divided or combined with other Warrants by 
surrender of this Warrant and any other Warrants with which it is to be 
combined at the principal office of the Company together with a written 
notice, signed by the Warrant Holder, specifying the names and denominations 
in which new Warrants are to be issued.

     Section 5.03.     Upon receipt by the Company of evidence reasonably 
satisfactory to it of the loss, theft, destruction, or mutilation of this 
Warrant, and (in the case of loss, theft, or destruction) of reasonably 
satisfactory indemnification, or (in the case of mutilation) upon surrender of 
this Warrant, the Company will execute and deliver a new Warrant relating to 
the same number of shares of Common Stock as this Warrant and the lost, 
stolen, destroyed, or mutilated Warrant will become void.  Any new Warrant 
executed and delivered in accordance with this Section 5.03 will constitute an 
additional contractual obligation of the Company, and will be valid and 
enforceable whether or not the Warrant which was believed to have been lost, 
stolen, or destroyed is subsequently presented for exercise.

                                  ARTICLE VI

                    Registration Under the Securities Act

     Section 6.01 (a) If, at any time during the period commencing on July 1, 
1995 and ending on June 30, 2001, The Company shall determine or be required 
to register any shares of the Company's Common Stock (whether on behalf of 
itself or any other person) under the Securities Act of 1933 on Forms S-1, S-
2, S-3, SB-1, or SB-2 (or if such forms are rescinded by the Securities and 
Exchange Commission (the "Commission") such forms as replace those forms), 
excluding any registration for the offering and sale of securities of the 
Company to its employees, it will notify the Warrant Holder in order that it 
may request that all or a part of shares of Common Stock issued or issuable 
upon exercise of this Warrant be included in the registration statement.  If 
requested by any Warrant Holder in writing within 20 days after the Company's 
notice, the Company will include the requested number of shares in such 
registration statement.  Any such request shall include the agreement of the 
Warrant Holder requesting the registration to execute and deliver the 
underwriting agreement, if any, to be executed and delivered in connection 
with such registration.  The Company may, however, decline to include all or a 
part of the requested number of shares in a registration statement pursuant to 
this section if it is advised by the investment banking firm managing the 
underwriting that such inclusion would adversely affect the offering of the 
shares to be covered by the proposed registration statement.

          (b)     The Company shall use its best efforts to file such post-
effective amendments to any registration statement described in this Section 6 
as shall be necessary to keep it effective until six months after the 
effective date of the registration statement or the date on which all of the 
shares of the Warrant Holders covered thereunder shall have been sold, 
whichever is earlier.

          (c)     As a condition to the Company's obligation under this 
Article VI to cause a registration statement or amendment to be filed or 
shares to be included in a registration statement, the Warrant Holder shall 
provide such information and execute such documents as may reasonably be 
required in connection with such registration.  In addition, the Company shall 
not be required to include such shares in a registration statement if it shall 
have received opinions of its and the Warrant Holder's counsel to the effect 
that the proposed disposition of such shares may be effected without 
registration under the Act.

          (d)     The expenses of the registration of Warrant Holders' shares 
(other than transfer taxes, underwriting commissions, and fees of Warrant 
Holders' counsel) shall be paid by the Company.

     Section 6.02.     Unless the resale of shares of Common Stock is the 
subject of an effective registration statement under the Securities Act, the 
certificates representing shares of Common Stock issued upon exercise of this 
Warrant may bear the following legend:

"THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN 
REGISTERED UNDER THE SECURITIES ACT OF 1933.   THE SHARES MAY NOT 
BE OFFERED OR SOLD, EXCEPT (i) PURSUANT TO AN EFFECTIVE 
REGISTRATION STATEMENT OR (ii) IN A TRANSACTION WHICH IS EXEMPT 
FROM THE REGISTRATION REQUIREMENTS OF THAT ACT."

                                 ARTICLE VII
                                Other Matters

     Section 7.01.     The provisions of this Warrant will bind, and inure to 
the benefit of, the Company and its successors and assigns and the Warrant 
Holder and its successors and assigns.

     Section 7.02 (a)  Any notice or other communication to the Company 
relating to this Warrant will be deemed given on the day when it is delivered 
or sent by facsimile transmission (with a confirmation copy sent by registered 
mail, return receipt requested), or on the third Business Day after the day on 
which it is sent by registered mail, return receipt requested, to the Company 
at the following address (or such other address as may be specified by the

          (b)     Any notice or other communication to the Warrant Holder will 
be deemed given when and as provided in Section 4.05.

     Section 7.03.     To the extent such documents are required to be sent 
by the Company to the holders of its outstanding Common Stock, the Company

	RE:	Registration Statement on Form SB-2
		Ixion Biotechnology, Inc.
		

Gentlemen:

	I have acted as counsel for Ixion Biotechnology, Inc. (the "Company")
in connection with the proposed public offering by the Company of four
hundred thousand (400,000) Units, each Unit being comprised of one (1) voting
Common Share (par value $.01) and .25 Charitable Benefit Warrant to purchase 
voting common share at $20.00 per share (the "Units").  In connection with the
proposed public offering and above-described registration statement, I have
reviewed the following:

1. The Certificate of Incorporation and amendments thereto of the Company;

2. The By-Laws and amendments thereto of the Company;

3. The minute books of the Company; and

On the basis of such investigation and the examination of such other records
as I deemed necessary, I am of the opinion that:

a) the Company has been duly incorporated and is validly existing under 
the laws of the State of Delaware; and

b) The 400,000 Units, the 400,000 Common Shares, and the 100,000 Charitable
Benefit Warrants have been duly authorized and the 400,000 common shares and
the underlying shares purchasable pursuant to the Charitable Benefit Warrants,
when issued, will be legally issued by the Company and will be fully paid and 
nonassessable.

	I consent to the filing of this opinion as an Exhibit for the purpose of 
registering all or a portion of the Common Shares described in Registration 
Statement on Form SB-2 under the relevant state securities laws.


                                      Sincerely,

                                      /s/ Bruce Brashear

                                      Bruce Brashear, Esq.


         Chattel Mortgage - Installment Sale of Equipment Agreement 

     This Chattel Mortgage - Installment Sale of Equipment Agreement, dated as 
of January 1, 1996, is between Ixion Biotechnology, Inc., a Delaware 
corporation with offices at 12085 Research Drive, Alachua, Florida (the 
"mortgagor") and Carl Therapeutic, Inc., a Florida corporation with offices at 
149 Turkey Creek, Alachua, Florida (the "mortgagee").

     The mortgagor hereby purchases from the mortgagee, subject to the terms 
and conditions set forth below, the laboratory equipment and disposables 
listed in Appendices A and B, in "as is condition," complete with manuals and 
standard attachments and equipment, delivery and acceptance of which is hereby 
acknowledged by the mortgagor as of the date first above stated.  

     The total time price for the Appendix A property is $32,309.00, of which 
nothing is payable on delivery, leaving a deferred balance of $32,309.00, 
payable in 36 monthly installments of $897.47 on the same day of each 
successive month, and commencing on August 1, 1996.  The final installment 
payable hereunder shall equal the amount of the deferred balance remaining 
due.  The total time price of the Appendix B property shall not exceed $2,610, 
of which nothing is payable on delivery.  If mortgagor places any Appendix B 
property into service during the period of this mortgage, the fair market 
value of such item shall be added to the final installment payable for the 
Appendix A property.  If no Appendix B property is placed in service during 
the term of this mortgage, mortgagor shall own such property free and clear 
without further payment. Interest is due on installments after maturity at the 
highest lawful contract rate, and if this mortgage be placed with an attorney 
for collection, 25% of the amount due hereunder shall be paid by the mortgagor 
as attorney's fees, or if prohibited, the amount permitted by law.

     1.  Grant.  To secure payment of the purchase price, the mortgagor 
grants, bargains, sells, and mortgages to the mortgagee, the above property 
described on Appendices A and B, to have and to hold unto the mortgagee, its 
representatives, successors, and assigns forever.

     2.  Defeasance.  Provided always that if the mortgagor shall perform all 
agreements and covenants herein, then this instrument shall be void, otherwise 
to remain in full force and effect.

     3.  Assignment.  No transfer, renewal, extension, or assignment of this 
mortgage, or any interest hereunder, or loss, injury, or destruction of the 
property shall release the mortgagor from its obligations hereunder; the 
assignee shall be entitled to all the rights of the mortgagee.

     4. Acceleration.  In the event the mortgagor defaults on any payment or 
fails to comply with any condition of this mortgage or a proceeding in 
bankruptcy, receivership, or insolvency be instituted against the mortgagor or 
its property, the full amount shall be immediately due and payable.

     The mortgagee's acceptance, after the full amount may have become 
immediately due and payable as hereinbefore provided, of any installment or 
payment shall not be deemed to alter or affect the mortgagor's obligations 
and/or the mortgagee's rights hereunder with respect to any subsequent 
payments or default therein.

     5.  Possession.  The property may remain in possession of the mortgagor 
as long as the conditions of this mortgage are fulfilled and shall remain 
strictly personal property.

     6.  Exclusion of Warranties.  There are no warranties, expressed or 
implied, representations, promises, or statements in connection with the sale 
of the property listed in Appendices A and B, except as set forth in 
manufacturer's warranty applying to equipment covered by this mortgage.

     7.  Taxes, Use, Transfer, Insurance.  The mortgagor shall keep said 
property free of all taxes, liens, and encumbrances; shall not use the same 
illegally or improperly; shall not transfer any interest in this mortgage or 
said property, except as set forth below; and shall not remove the same from 
the premises stated (except that such property may be moved pursuant to a 
general transfer of operations from the current premises to another location) 
without the permission of the holder of this chattel mortgage.  The mortgagor 
shall keep the property insured against loss by fire to properly protect all 
interests therein.  The proceeds of any insurance, whether paid by reason of 
loss, injury, return premium, or otherwise, shall be applied toward the 
replacement of the property or payment of this obligation at the option of the 
mortgagee.  The mortgagor may sell any item of the property not necessary to 
the conduct of its operations (as determined by the mortgagor), provided it 
shall receive not less than the sales price therefor set forth in Appendix A 
or B, and provided further that the proceeds of such sale up to such sales 
price be added to the next monthly installment due to the mortgagee.

     8. Repossession, Right of Entry, Sale, Application of Proceeds.  If the 
mortgagor defaults in complying with the terms hereof, and fails to cure such 
default within 30 days of receiving written notice thereof from the mortgagee, 
the mortgagee may take possession of said property without further demand, 
including any equipment or accessories thereto, possession by the mortgagor 
after such expired grace period being unlawful; and for this purpose the 
mortgagee may enter upon the premises where said property may be and remove 
same.  The mortgagee may resell said property, so retaken, at public or 
private sale, without demand for performance, with or without notice to the 
mortgagor (if given, notice by mail to the address given above being 
sufficient) with or without having such property at the place of sale, and 
upon such terms and in such manner as the mortgagee may determine; the 
mortgagee may bid at any public sale.  For the proceeds of any such sale, the 
mortgagee shall deduct all expenses for retaking, repairing, and selling such 
property, including a reasonable attorney's fee.  The balance thereof shall be 
applied to the deferred balance due; any surplus shall be paid over to the 
mortgagor; in case of deficiency the mortgagor shall pay the same with 
interest.

     9.  Waiver.  The mortgagor hereby waives the right to remove any legal 
action from the court originally acquiring jurisdiction.

     IN WITNESS WHEREOF, the undersigned have given their hand and seal this
day of April, 1996.

     IXION BIOTECHNOLOGY, INC.

     DEFERRED COMPENSATION PLAN AGREEMENT 


THIS AGREEMENT made this 1st  day of January, 1994 by and between Ixion 
Biotechnology, Inc. (the "Company") and Weaver H. Gaines (the "Employee"):

     WITNESSETH:

WHEREAS, the Employee occupies a position of key significance with the 
Company and the Company desires to encourage the Employee to remain with the 
Company, to make and to continue to make contributions to the Company's 
growth;

WHEREAS, by consent dated January 3, 1994, the Company's Board of 
Directors adopted a Deferred Compensation Plan for officers, key employees, 
and key consultants of the Company  (the "Plan"), permitting the Employee to 
defer receipt of all or a portion of his compensation to be paid in the future 
in accordance with the terms and conditions herein set forth.

NOW, THEREFORE, the parties agree as follows:

1.  Payment of Compensation. 


 Beginning January 3, 1994, and thereafter for all future calendar years 
until the Employee provides the Company with written notice to discontinue or 
reduce the deferral of future compensation hereunder, 100% of each installment 
of Employee's annual compensation (including annual or long term incentive 
compensation, if any) shall be deferred and credited in accordance with 
Section 2 below.  (The beginning date in the preceding sentence shall be the 
first business day of a future calendar year, unless the Employee executes 
this Agreement within thirty days  of becoming eligible for the Plan, in which 
event the beginning date may be the first day of any future month.)  Any 
remaining portion of the Employee's compensation shall be paid currently in 
accordance with the Company's normal payroll procedures.  The Employee's 
regular stipulated rate of pay from the Company for full-time service shall 
not be affected by the deferral provided for herein and, therefore, none of 
the Company's non-qualified welfare plans, if any, the benefits of which are a 
function of the regular stipulated rate of pay, shall be affected by such 
deferral.

2.  Employee's Account: Credits and Interest.

(a)  An unfunded deferred compensation account  (the "Account") 
will be established for the Employee.  The only obligation of the Company with 
respect to the Account is to make the payments provided for under this 
Agreement when they become payable, and that any amount credited to such 
Account will be solely for record-keeping purposes and shall not be considered 
to be held in trust or in escrow or in any way vested in the Employee.

(b)  The Company will credit to the Account an amount equal to the 
percent of compensation specified in Section 1.

(c)  (i)     Until payments under this Agreement begin, the 
Company will also credit additional amounts to the Account.   The Board of 
Directors will establish an annual interest rate which shall remain in effect 
until changed by the Board at the beginning of each year.  The initial rate 
shall be 8%.

       (ii)  After payments under this Agreement begin, the 
Company will also credit additional amounts to the Account.  Such additional 
amounts shall be equal to the amount of interest set forth in Subsection 
2(c)(i) above, unless greater additional amounts are otherwise ordered by the 
Board of Directors.

3.     Payments from Deferred Compensation Account.

(a)  The amount in the Employee's Account will be paid out as 
indicated below provided, in all cases, the Company has sufficient cash to be 
able prudently to make such payments.

  (i)  In the event of the Employee's termination of employment by 
death, payment to the beneficiary will commence on the first day of the 
calendar month following the 90th day after the Employee's death, provided 
that the Company has been provided with the necessary documents.

  (ii)  In the event of the Employee's termination of employment, 
other than by death, disability or retirement:  [Initial one.]

                 on the first day of the calendar month following 
the 90th day after the Employee's termination of employment; or

                 on the first day of the calendar month following 
the month in which the Employee attained 65 years of age.

(b)  Cash payment shall be in the form of monthly installments, as 
nearly equal as may be practicable, but with appropriate adjustment for 
changes required under Subsection (c)(ii) of Section 2, over a period of years 
to be selected by Employee or in a single sum.  A change in either the elected 
form of payment or the number of years for installment payments may be made at 
any time prior to the calendar year during which the initial benefit becomes 
payable.  The Employee, in the same manner as his may make beneficiary 
designations, may elect that payments coming due at or after his death shall 
be either in one sum or in installments.  Any payment coming due during the 
Employee's lifetime shall be payable to the Employee.  Any payment coming due 
at or after the Employee's death shall be paid when due to the beneficiary 
designated by the Employee.  The beneficiary designated by the Employee must 
be his spouse, child or children, grandchild or grandchildren, sibling or 
siblings, the Employee's executors or administrators, or a trust established 
by the instrument probated as the Employee's Will.  If no such designation is 
in effect at the time any payment becomes due, it shall be paid to the 
Employee's executors or administrators.  Beneficiary designations and changes 
thereof may be made during the Employee's lifetime by the Employee by written 
notice filed with the Company.  Such designation and any subsequent change 
shall take effect as of the date the notice was signed, upon recording and 
acceptance by the Company, subject to any payment made by the Company or 
action taken by it before receipt of the notice.

(c)  In the event of Employee's termination of employment either 
by death or without cause, at the election of the Employee or the Employee's 
executors or administrators, made on or before the 90th day following the date 
of termination, Employee may convert all or a portion of the amounts in the 
Account into common stock of the Company at a price per share not greater than 
the lowest price per share (adjusted for stock splits, stock dividends, the 
issuance of convertible securities, warrants or options, or other dilution), 
at which shares of the Company's common stock have been issued (or agreed to 
be issued)  at any time in the 365 days preceding the date of termination.  
Notice of the election must be in writing and must specify the amount of such 
Account to be so converted.  The common stock shall be issued as of the date 
of the notice, upon recording by the Company.

(d)  A termination shall be deemed without cause if, without 
Employee's written consent, any of the following events occur:

    (i)  The Employee is assigned any duties inconsistent with his 
status in the position held immediately prior to such assignment, or has the 
nature or status of his responsibilities altered in a substantially adverse 
way; 

     (ii)  The Company reduces the Employee's annual base salary 
in effect as of the date of this Agreement, or as the same may be increased 
from time to time;

     (iii)  The Company's offices where the Employee is working 
are moved  to a location more than 50 miles from the location of such offices;

    (iv)  The Company fails to pay any portion of current 
compensation, or fails to pay any portion of an installment of deferred 
compensation under any deferred compensation program of the Company within 30 
days of the date such compensation is due; 

    (v)  The Company fails to continue in effect any compensation 
plan in which the Employee is participating which is material to such 
Employee's total compensation;

    (vi)  The Company fails to continue to provide the Employee 
with benefits substantially similar to those, if any, previously enjoyed under 
any of the Company's pension, saving, health, or other welfare or benefit 
plans;  

    (vii)  The Company takes any other action which directly or 
indirectly materially reduces any of the benefits referred to above, or 
reduces any fringe benefits enjoyed by the Employee (including, without 
limitation, days of paid vacation); or

    (ix)  The Company materially breaches any employment agreement 
with the Employee.

4.     Benefits May Not be Assigned or Attached.

No benefit hereunder may be assigned, anticipated or hypothecated and, 
to the extent permitted by law, no sum payable under this Agreement shall be 
subject to legal process or attachment for payment of any claim payee 
hereunder.

5.     No Obligations to Continue Employment.

Subject to the provisions of Section 3(d) above, nothing contained in 
this Agreement shall in any way otherwise obligate the Company to retain the 
Employee in its employment for any period of time, nor in any way otherwise 
affect the Company's right to change at any time the Employee's compensation, 
the method or conditions for payment thereof, or any other aspect of the 
Employee's employment.

6.  Duration of Agreement.

This Agreement shall remain effective and continue in force until such 
time as it may be amended or terminated by the parties hereto.

7.  Election of Payment . 

If the Employee has not elected to convert his Account into common stock 
of the Company, such Account shall be paid as follows:   [Initial one.]

          (a)  Single sum.
          (b)  Monthly Installments over          (5 or 10 years)

IN WITNESS WHEREOF the parties hereto have duly executed this Agreement 
as of the day and year first above written.

                    DEFERRED COMPENSATION PLAN AGREEMENT 


THIS AGREEMENT made this 1st  day of June, 1994 by and between Ixion 
Biotechnology, Inc. (the "Company") and Ammon B. Peck ("Peck"):

                                 WITNESSETH:

     WHEREAS, Peck occupies a position of key significance with the Company 
and the Company desires to encourage Peck to remain with the Company, to make 
and to continue to make contributions to the Company's growth;

     WHEREAS, by consent dated January 3, 1994, the Company's Board of 
Directors adopted a Deferred Compensation Plan for officers, key employees, 
and key consultants of the Company  (the "Plan"), permitting Peck to defer 
receipt of all or a portion of his compensation to be paid in the future in 
accordance with the terms and conditions herein set forth.

     NOW, THEREFORE, the parties agree as follows:

     1.  Payment of Compensation. 

      Beginning June 1, 1994, and thereafter for all future calendar years 
until Peck provides the Company with written notice to discontinue or reduce 
the deferral of future compensation hereunder, 100% of each installment of 
Peck's compensation (including annual or long term incentive compensation, if 
any) shall be deferred and credited in accordance with Section 2 below.  (The 
beginning date in the preceding sentence shall be the first business day of a 
future calendar year, unless Peck executes this Agreement within thirty days  
of becoming eligible for the Plan, in which event the beginning date may be 
the first day of any future month.)  Any remaining portion of Peck's 
compensation shall be paid currently in accordance with the Company's normal 
payroll procedures.  Peck's regular stipulated rate of pay from the Company, 
if any,  shall not be affected by the deferral provided for herein and, 
therefore, none of the Company's non-qualified welfare plans, if any, the 
benefits of which are a function of the regular stipulated rate of pay, shall 
be affected by such deferral.

     2.  Peck's Account: Credits and Interest.

          (a)  An unfunded deferred compensation account  (the "Account") will 
be established for Peck.  The only obligation of the Company with respect to 
the Account is to make the payments provided for under this Agreement when 
they become payable, and that any amount credited to such Account will be 
solely for record-keeping purposes and shall not be considered to be held in 
trust or in escrow or in any way vested in Peck.

          (b)  The Company will credit to the Account an amount equal to the 
percent of compensation specified in Section 1.

          (c)  (i)     Until payments under this Agreement begin, the Company 
will also credit additional amounts to the Account.   The Board of Directors 
will establish an annual interest rate which shall remain in effect until 
changed by the Board at the beginning of each year.  The initial rate shall be 
8%.

                 (ii)  After payments under this Agreement begin, the Company 
will also credit additional amounts to the Account.  Such additional amounts 
shall be equal to the amount of interest set forth in Subsection 2(c)(i) 
above, unless greater additional amounts are otherwise ordered by the Board of 
Directors.

     3.     Payments from Deferred Compensation Account.

          (a)  The amount in Peck's Account will be paid out as indicated 
below provided, in all cases, the Company has sufficient cash to be able 
prudently to make such payments.

            (i)  In the event of Peck's termination of employment by death, 
payment to the beneficiary will commence on the first day of the calendar 
month following the 90th day after Peck's death, provided that the Company has 
been provided with the necessary documents.

            (ii)  In the event of Peck's termination of employment, other than 
by death, disability or retirement:  [Initial one.]

                           on the first day of the calendar month following 
the 90th day after Peck's termination of employment; or

                           on the first day of the calendar month following 
the month in which Peck attained 65 years of age.

          (b)  Cash payment shall be in the form of monthly installments, as 
nearly equal as may be practicable, but with appropriate adjustment for 
changes required under Subsection (c)(ii) of Section 2, over a period of years 
to be selected by Consultant or in a single sum.  A change in either the 
elected form of payment or the number of years for installment payments may be 
made at any time prior to the calendar year during which the initial benefit 
becomes payable.  Peck, in the same manner as his may make beneficiary 
designations, may elect that payments coming due at or after his death shall 
be either in one sum or in installments.  Any payment coming due during Peck's 
lifetime shall be payable to Peck.  Any payment coming due at or after Peck's 
death shall be paid when due to the beneficiary designated by Peck.  The 
beneficiary designated by Peck must be his spouse, child or children, 
grandchild or grandchildren, sibling or siblings, Peck's executors or 
administrators, or a trust established by the instrument probated as Peck's 
Will.  If no such designation is in effect at the time any payment becomes 
due, it shall be paid to Peck's executors or administrators.  Beneficiary 
designations and changes thereof may be made during Peck's lifetime by Peck by 
written notice filed with the Company.  Such designation and any subsequent 
change shall take effect as of the date the notice was signed, upon recording 
and acceptance by the Company, subject to any payment made by the Company or 
action taken by it before receipt of the notice.

          (c)  In the event of Consultant's termination of employment either 
by death or without cause, at the election of Peck or Peck's executors or 
administrators, made on or before the 90th day following the date of 
termination, Consultant may convert all or a portion of the amounts in the 
Account into common stock of the Company at a price per share not greater than 
the lowest price per share (adjusted for stock splits, stock dividends, the 
issuance of convertible securities, warrants or options, or other dilution), 
at which shares of the Company's common stock have been issued (or agreed to 
be issued)  at any time in the 365 days preceding the date of termination.  
Notice of the election must be in writing and must specify the amount of such 
Account to be so converted.  The common stock shall be issued as of the date 
of the notice, upon recording by the Company.

          (d)  A termination shall be deemed without cause if, without 
Consultant's written consent, any of the following events occur:

              (i)  Peck is assigned any duties inconsistent with his status in 
the position held immediately prior to such assignment, or has the nature or 
status of his responsibilities altered in a substantially adverse way; 

               (ii)  The Company reduces Peck's annual base salary in effect 
as of the date of this Agreement, or as the same may be increased from time to 
time;

     IXION BIOTECHNOLOGY, INC.

     DEFERRED COMPENSATION PLAN AGREEMENT 


THIS AGREEMENT made this 1st  day of April, 1994 by and between Ixion 
Biotechnology, Inc. (the "Company") and David C. Peck (the "Employee"):

     WITNESSETH:

WHEREAS, the Employee occupies a position of key significance with the 
Company and the Company desires to encourage the Employee to remain with the 
Company, to make and to continue to make contributions to the Company's 
growth;

WHEREAS, by consent dated January 3, 1994, the Company's Board of 
Directors adopted a Deferred Compensation Plan for officers, key employees, 
and key consultants of the Company  (the "Plan"), permitting the Employee to 
defer receipt of all or a portion of his compensation to be paid in the future
in accordance with the terms and conditions herein set forth.

NOW, THEREFORE, the parties agree as follows:

1.  Payment of Compensation. 


 Beginning April 1, 1994, and thereafter for all future calendar years 
until the Employee provides the Company with written notice to discontinue or 
reduce the deferral of future compensation hereunder, 100% of each installment 
of Employee's annual compensation (including annual or long term incentive 
compensation, if any) shall be deferred and credited in accordance with 
Section 2 below.  (The beginning date in the preceding sentence shall be the 
first business day of a future calendar year, unless the Employee executes 
this Agreement within thirty days  of becoming eligible for the Plan, in which 
event the beginning date may be the first day of any future month.)  Any 
remaining portion of the Employee's compensation shall be paid currently in 
accordance with the Company's normal payroll procedures.  The Employee's 
regular stipulated rate of pay from the Company for full-time service shall 
not be affected by the deferral provided for herein and, therefore, none of 
the Company's non-qualified welfare plans, if any, the benefits of which are a 
function of the regular stipulated rate of pay, shall be affected by such 
deferral.

2.  Employee's Account: Credits and Interest.

(a)  An unfunded deferred compensation account  (the "Account") 
will be established for the Employee.  The only obligation of the Company with 
respect to the Account is to make the payments provided for under this 
Agreement when they become payable, and that any amount credited to such 
Account will be solely for record-keeping purposes and shall not be considered 
to be held in trust or in escrow or in any way vested in the Employee.

(b)  The Company will credit to the Account an amount equal to the 
percent of compensation specified in Section 1.

(c)  (i)     Until payments under this Agreement begin, the 
Company will also credit additional amounts to the Account.   The Board of 
Directors will establish an annual interest rate which shall remain in effect 
until changed by the Board at the beginning of each year.  The initial rate 
shall be 8%.

       (ii)  After payments under this Agreement begin, the 
Company will also credit additional amounts to the Account.  Such additional 
amounts shall be equal to the amount of interest set forth in Subsection 
2(c)(i) above, unless greater additional amounts are otherwise ordered by the 
Board of Directors.

3.     Payments from Deferred Compensation Account.

(a)  The amount in the Employee's Account will be paid out as 
indicated below provided, in all cases, the Company has sufficient cash to be 
able prudently to make such payments.

  (i)  In the event of the Employee's termination of employment by 
death, payment to the beneficiary will commence on the first day of the 
calendar month following the 90th day after the Employee's death, provided 
that the Company has been provided with the necessary documents.

  (ii)  In the event of the Employee's termination of employment, 
other than by death, disability or retirement:  [Initial one.]

                 on the first day of the calendar month following 
the 90th day after the Employee's termination of employment; or

                 on the first day of the calendar month following 
the month in which the Employee attained 65 years of age.

(b)  Cash payment shall be in the form of monthly installments, as 
nearly equal as may be practicable, but with appropriate adjustment for 
changes required under Subsection (c)(ii) of Section 2, over a period of years 
to be selected by Employee or in a single sum.  A change in either the elected 
form of payment or the number of years for installment payments may be made at 
any time prior to the calendar year during which the initial benefit becomes 
payable.  The Employee, in the same manner as his may make beneficiary 
designations, may elect that payments coming due at or after his death shall 
be either in one sum or in installments.  Any payment coming due during the 
Employee's lifetime shall be payable to the Employee.  Any payment coming due 
at or after the Employee's death shall be paid when due to the beneficiary 
designated by the Employee.  The beneficiary designated by the Employee must 
be his spouse, child or children, grandchild or grandchildren, sibling or 
siblings, the Employee's executors or administrators, or a trust established 
by the instrument probated as the Employee's Will.  If no such designation is 
in effect at the time any payment becomes due, it shall be paid to the 
Employee's executors or administrators.  Beneficiary designations and changes 
thereof may be made during the Employee's lifetime by the Employee by written 
notice filed with the Company.  Such designation and any subsequent change 
shall take effect as of the date the notice was signed, upon recording and 
acceptance by the Company, subject to any payment made by the Company or 
action taken by it before receipt of the notice.

(c)  In the event of Employee's termination of employment either 
by death or without cause, at the election of the Employee or the Employee's 
executors or administrators, made on or before the 90th day following the date 
of termination, Employee may convert all or a portion of the amounts in the 
Account into common stock of the Company at a price per share not greater than 
the lowest price per share (adjusted for stock splits, stock dividends, the 
issuance of convertible securities, warrants or options, or other dilution), 
at which shares of the Company's common stock have been issued (or agreed to 
be issued)  at any time in the 365 days preceding the date of termination.  
Notice of the election must be in writing and must specify the amount of such 
Account to be so converted.  The common stock shall be issued as of the date 
of the notice, upon recording by the Company.

(d)  A termination shall be deemed without cause if, without 
Employee's written consent, any of the following events occur:

    (i)  The Employee is assigned any duties inconsistent with his 
status in the position held immediately prior to such assignment, or has the 
nature or status of his responsibilities altered in a substantially adverse 
way; 

     (ii)  The Company reduces the Employee's annual base salary 
in effect as of the date of this Agreement, or as the same may be increased 
from time to time;

     (iii)  The Company's offices where the Employee is working 
are moved  to a location more than 50 miles from the location of such offices;

    (iv)  The Company fails to pay any portion of current 
compensation, or fails to pay any portion of an installment of deferred 
compensation under any deferred compensation program of the Company within 30 
days of the date such compensation is due; 

    (v)  The Company fails to continue in effect any compensation 
plan in which the Employee is participating which is material to such 
Employee's total compensation;

    (vi)  The Company fails to continue to provide the Employee 
with benefits substantially similar to those, if any, previously enjoyed under 
any of the Company's pension, saving, health, or other welfare or benefit 
plans;  

    (vii)  The Company takes any other action which directly or 
indirectly materially reduces any of the benefits referred to above, or 
reduces any fringe benefits enjoyed by the Employee (including, without 
limitation, days of paid vacation); or

    (ix)  The Company materially breaches any employment agreement 
with the Employee.

4.     Benefits May Not be Assigned or Attached.

No benefit hereunder may be assigned, anticipated or hypothecated and, 
to the extent permitted by law, no sum payable under this Agreement shall be 
subject to legal process or attachment for payment of any claim payee 
hereunder.

5.     No Obligations to Continue Employment.

Subject to the provisions of Section 3(d) above, nothing contained in 
this Agreement shall in any way otherwise obligate the Company to retain the 
Employee in its employment for any period of time, nor in any way otherwise 
affect the Company's right to change at any time the Employee's compensation, 
the method or conditions for payment thereof, or any other aspect of the 
Employee's employment.

6.  Duration of Agreement.

This Agreement shall remain effective and continue in force until such 
time as it may be amended or terminated by the parties hereto.

7.  Election of Payment . 

If the Employee has not elected to convert his Account into common stock 
of the Company, such Account shall be paid as follows:   [Initial one.]

          (a)  Single sum.
          (b)  Monthly Installments over          (5 or 10 years)

AGREEMENT TO PURCHASE SHARES, dated as of October 10, 
1994, among IXION BIOTECHNOLOGY, INC., a Delaware 
corporation ("Seller") and the persons listed in Attachment 
A hereto ("Purchasers").


Purchasers desire to acquire from the Seller, and Seller desires to sell 
to Purchasers, the number of shares of common stock, $0.10 par value set forth 
opposite their names on Attachment A, or a total of 130,000 shares (the 
"Shares"), for the purchase price and on the terms and conditions set forth 
below.

1.  Purchase and Sale of Shares.  Seller agrees to issue and deliver to 
Purchasers fully-paid and nonassessable Shares, free and clear of all liens, 
claims, options, charges, and encumbrances whatsoever, and each Purchaser 
agrees to purchase the Shares set forth opposite his, her, or their names as 
set forth on Attachment A, and to pay Seller the purchase price, such payment 
to be not later than November 4, 1994.  The purchase price to be paid by the 
Purchasers shall be $0.10 per share or, in the aggregate,  the amount set 
forth opposite his, her, or their name on Attachment A.  Payment shall be made 
by delivery to Seller of a check payable to Seller.

2.  Closing.  The closing of each purchase hereunder shall take place in 
the offices of the Seller at One Progress Blvd., Alachua, FL 32615.  At the 
Closing, each Purchaser will deliver to Seller:

(i)   A check in the amount set forth opposite his, her, or their 
names on Attachment A; and

(ii)  An executed copy of the investment and representation letter 
in the form attached as Attachment B hereto;

and the Seller will execute and deliver a fully paid and nonassessable 
certificate for the number of Shares set forth opposite his, her, or their 
name on Attachment A hereto.

3.  Access to Books, Records, and Information of Seller.

3.1  Purchasers acknowledge that they have received the following 
information and documents from Seller:

a)  Unaudited balance sheet and income statement and 
accompanying notes for the period commencing with the founding of 
the Company and ending December 31, 1993;

b)  Unaudited balance sheet, income statement, and statement 
of cash flow for the nine months ended September 30, 1994;  

c)  A copy of the Company's Certificate of Incorporation and 
Bylaws;

d)  A copy of the Company profile dated October, 1994; and

e)  Information to the effect of the following:

  the Company is a start-up company which has had 
substantial operating losses since its founding;

  such losses are continuing and are expected to continue 
for the foreseeable future;

  there is no assurance that the Company will be able to 
obtain financing sufficient to fund its objectives, and 
therefore this investment is speculative and may fail;

  the Company has no material tangible assets and owns no 
intellectual property rights, or other intangible property 
and that there is no assurance that it will ever have any;

  the Company has negotiated with the University of Florida 
for an exclusive license to certain technology covered by a 
pending U.S. patent application, but that there is no 
assurance that the University will execute a license on 
reasonable (or any) terms with the Company, and, that if 
such license is executed, there is no assurance that the 
patent application is valid or that a patent will issue, and 
there is no assurance that, assuming the license is executed 
and the patent issued, that a commercially saleable product 
can be developed therefrom; and

  the Company has no intellectual property rights regarding 
certain discoveries of Dr. Peck in the field of Islets of 
Langerhan and that, while it expects to negotiate with the 
University of Florida to obtain such rights, there is no 
assurance that it will be able to obtain any, and that if it 
is successful in obtaining such rights, it is likely that 
the Company will have to dilute its interest in such rights 
in order to finance further research and development in the 
field. 

3.2    Purchasers acknowledge that prior to the signing hereof, 
Seller has afforded the Purchasers (or any authorized representatives of such 
Purchasers) free and full access to all books, tax returns, records, founders, 
or officials of the Company.  

4.  Representations of the Seller.

4.1  The Company is a corporation duly organized, existing, and in 
good standing under the laws of the State of Delaware and is duly qualified in 
the State of Florida.  The Company has the corporate power to own, operate, or 
lease its properties, and to carry on its business.  

4.2  The Shares to be issued have been validly authorized and, 
upon payment by the Purchaser of the purchase price, will be fully paid and 
nonassessable.

4.3  Attached hereto as Attachment C are 

(i)  the unaudited balance sheet and income statement of the 
Company as at December 31, 1993, and for the period commencing 
with the founding of the Company and ending on December 31, 1993, 
with accompanying notes,  and

(ii)  the unaudited balance sheet, income statement, and statement

pending or threatened against or affecting the Company.

4.7  Seller has made no representations, warranties or 
projections, orally, or in writing, except those expressly set forth in this 
Agreement.

5.  Representations and Warranties of the Purchasers.  

5.1  The Shares which are to be issued and delivered to Purchasers 
pursuant to the terms of this Agreement are being acquired by them for their 
own accounts for investment and not with a view of the resale or distribution 
there of, and they have no present intention of making any distribution or 
disposition of any of such Shares.  Purchaser understands that the Shares are 
being sold to them in a transaction which is exempt from the registration 
requirements of the Securities Act of 1933 (the "Act"), and that such Shares 
must be held by them and not resold unless they are subsequently registered 
under the Act or an exemption from such registration is available and the 
certificates issued to evidence such Shares shall contain a legend to the 
foregoing effect.

5.2  The offer by the Purchasers to purchase the Shares was 
unsolicited.

5.3  Notwithstanding the forgoing, or the provisions of Section 6 
below, the Purchasers agree that they will not dispose, by sale, gift, or 
otherwise, any of the Shares before November 4, 1999 without the express 
written consent of the Company.  Such consent may be given only by the 
President, the Chairman of the Board, or by vote of the Directors.

5.4  Purchasers have received and carefully read the Company's 
unaudited financial statements, its corporate documents, the Company profile 
dated October, 1994, and this Agreement and have not been furnished with any 
offering materials or literature relating to the Company other than as stated 
herein.

5.5  Purchasers have had a reasonable opportunity to ask questions 
of and receive answers from the Company concerning the Company and the Shares, 
and any such questions have been answered to their full satisfaction.

5.6  Purchasers have such knowledge and expertise in financial and 
business matters that they are capable of evaluating the merits and risks 
involved in an investment in the Shares; they are financially able to bear the 
economic risk of the investment in the Shares, including a total loss of such 
investment.

5.7  Purchasers have adequate means of providing for their current 
needs and have no need for liquidity in this investment.  Purchasers have no 
reason to anticipate any material change in their financial condition for the 
foreseeable future.

5.8  Purchasers are aware that the purchase of the Shares is a 
speculative investment involving a high degree of risk and that there is no 
guarantee that the Purchasers will realize any gain from this investment, and 
that the Purchasers could lose the total amount of their investment.

5.9  Purchasers understand that no federal or state agency has 
made any finding or determination regarding the fairness of this offering, nor 
any recommendation or endorsement of the offering.

5.10 Except as set forth in this Agreement, no representations or 
warranties have been made to the Purchasers by the Company, and in entering 
into this transaction, the Purchasers are not relying upon any information 
other than that referred to herein.  No person has made any representation or 
warranties as to the accuracy or completeness of the information contained in 
the Company profile or the unaudited financial statements.

5.11 Purchasers understand that the Shares are being offered and 
sold to them in reliance on specific exemptions from the registration 
requirements of federal and state securities laws and that the Company is 
relying upon the truth and accuracy of the representations, warranties, 
agreements, acknowledgements, and understandings of the Purchasers set forth 
herein in order to determine the applicability of such exemptions and the 
suitability of Purchasers to acquire the Shares. 
6.  Inclusion in Registrations Statements

6.1  If, at any time during the period commencing on October 10, 
1994 and ending on October 9, 2004, Ixion shall determine or be required to 
register any shares of Ixion common stock (whether on behalf of itself or any 
other person) under the Act on Forms S-1, S-2, S-3, SB-1, or SB-2 (or if such 
forms are rescinded by the Securities and Exchange Commission, the forms which 
supplant such forms), excluding any registration for the offering and sale of 
securities of Ixion to its employees, it will notify the Purchasers in order 
that they may request that all or a part of the Shares be included in the 
registration statement.  If requested by any Purchaser in writing within 20 
days after Ixion's notice, Ixion will include the requested number of shares 
in such registration statement.  Any such request shall include the agreement 
of the Purchaser requesting the registration to execute and deliver the 
underwriting agreement, if any, to be executed and delivered in connection 
with such registration.  The Company may, however, decline to include all or a 
part of the requested number of shares in a registration statement pursuant to 
this section if it is advised by the investment banking firm managing the 
underwriting that such inclusion would adversely affect the offering of the 
shares to be covered by the proposed registration statement.

6.2  Ixion shall use its best efforts to file such post-effective 
amendments to any registration statement described in this Section 6 as shall 
be necessary to keep it effective until six months after the effective date of 
the registration statement or the date on which all of the shares of the 
Purchasers covered thereunder shall have been sold, whichever is earlier.  

6.3  As a condition to Ixion's obligation under this Section 6 to 
cause a registration statement or amendment to be filed or shares to be 
included in a registration statement, the Purchasers shall provide such 
information and execute such documents as may reasonably be required in 
connection with such registration.  In addition, Ixion shall not be required 
to include such shares in a registration statement if it shall have received 
opinions of its and the Purchaser's counsel to the effect that the proposed 
disposition of such shares may be effected without registration under the Act.

6.4  The expenses of the registration of Purchasers' shares shall 
be paid by Ixion.

7.  Miscellaneous

7.1  This Agreement shall be construed in accordance with the laws 
of the State of Florida.

7.2  This Agreement constitutes the entire agreement among the 
parties hereto and supersedes all prior written or oral communications or 
understandings among the parties and cannot be changed except by an instrument 
in writing signed by all the parties.

7.3  This Agreement may be executed in any number of counterparts, 
each of which shall be an original, but all of which together shall constitute 
one and the same instrument.
7.4   Where notices are called for in this Agreement, such notices 
shall be deemed given when deposited in the U.S. mail, postage prepaid, and 
sent to the following addresses (or such other addresses notice of which shall

amount ("Redemption Price"), plus accrued and unpaid interest, if any, thereon 
to the date fixed for redemption ("Redemption Date").  The Company may, but

shall deem fair and appropriate and which may provide for the selection for 
redemption of portions of the principal of Notes of a denomination not less 
than $100.

     For all purposes of this Agreement, unless the context otherwise 
requires, all provisions relating to the redemption of Notes shall relate, in 
the case of any Note redeemed or to be redeemed only in part, to the portion 
of the principal of such Note which has been or is to be redeemed.

Notes or portions thereof accepted for redemption.  If the Notes are accepted 
for redemption, the Note Purchasers may exercise the conversion rights set

redemption has been accepted, at such Holder's address appearing in the Note 
Register.

     Each notice of acceptance of an offer for redemption shall state:

     (1)     the Redemption Date agreed to by the Company,

     (2)     the Redemption Price,

     (3)     if less than all Notes offered for redemption (or less than all 
the outstanding principal amount of a Note offered for redemption) is to be 
redeemed, the identification (and in the case of partial redemption, the 
respective principal amounts) of the Notes to be redeemed,

     (4)     that on the Redemption Date, the Redemption Price will become due 
and payable upon each such Note, and that interest thereon shall cease to 
accrue from and after said date; and

     (5)     the place where such Notes are to be surrendered for payment of 
the Redemption Price, which shall be the office of the Company unless 
otherwise indicated.

     Section 7.4     Notes Payable on Redemption Date.  Notice of acceptance 
of 
offer for redemption having been given as aforesaid, the Notes so to be 
redeemed shall, on the Redemption Date, become due and payable at the 
Redemption Price herein specified and from and after such date, unless the 
Company shall default in the payment of the Redemption Price, such Notes shall 
cease to bear interest.  Upon surrender of such Notes for redemption in 
accordance with said notice, such Notes shall be paid by the Company at the 
Redemption Price.  Installments of interest whose stated maturity is on the 
Redemption Date shall be payable to the Holders of such Notes registered as of 
the record date for such interest installment as provided in Section 3.1 
hereof.

     If any Note accepted for redemption shall not be so paid upon surrender 
thereof for redemption, the principal shall, until paid, bear interest from 
the Redemption Date at the rate borne by the Note.

     Section 7.5     Notes Redeemed in Part.  Any Note which is to be redeemed 
only in part shall be surrendered to the Company with, if the Company so 
requires, due endorsement by, or a written instrument of transfer in form

Holder's attorney duly authorized in writing, and the Company shall execute 
and deliver to the Holder of such Note without service charge, a new Note or

Nov      $4.10          $3.70           $3.30           $2.90           2.50
Feb      $4.00          $3.60           $3.20           $2.80           2.40
May      $3.90          $3.50           $3.10           $2.70           2.30

     Section 8.2     Surrender of Note.  In order to exercise the conversion 
privilege, the Holder shall give written notice to the Company at the 
Company's principal office at least three (3) days prior to such conversion 
that the Holder elects to convert the Note, specifying the principal amount of 
the Note to be converted, and shall surrender the Note to the Company on or 
before the Conversion Date at such office.  Such notice shall also state-the 
name or names, together with address or addresses, in which the certificate or 
certificates for Conversion Shares shall be issued. The Notes surrendered for 
conversion shall, unless the Conversion Shares are to be issued in the same 
name as the name of the original Holder, be accompanied by instruments of 
transfer, in form satisfactory to the Company, duly executed by the Holder or 
its duly authorized attorney. As promptly as practicable after the Conversion 
Date, the Company shall issue and shall deliver at such office or agency to 
the Holder, a certificate or certificates for the number of full shares of 
Common Stock issuable upon the conversion of the Notes in accordance with the 
provisions of this Article VIII, and a new Note representing the principal 
balance if any, with respect to which the surrendered Note shall not then have 
been converted shall also be delivered to the Holder.

     Section 8.3     No Fractional Shares.  No fractional shares of Common 
Stock 
shall be issued upon conversion of the Notes.  In the event that any portion 
of principal amount of the Notes would be converted into only a fractional 
interest in a share of Common Stock in connection with such conversion, then 
the Company shall, in lieu thereof, pay to the Holder the principal amount 
representing such fractional interest.

     Section 8.4      Adjustment of Conversion Price.  The Conversion Price 
shall be adjusted from time to time such that, in case the Company shall 
hereafter: (i) pay a dividend or make a distribution on its Common Stock in 
shares of Common Stock, (ii) subdivide its outstanding shares of Common Stock 
into a greater number of shares, (iii) combine its outstanding shares of 
Common Stock into a smaller number of shares, or (iv) issue by 
reclassification of its Common Stock any shares of capital stock of the 
Company, the Conversion Price in effect immediately prior to such action shall 
be adjusted so that the Holder shall be entitled to receive the number of 
shares of Common Stock or other capital stock of the Company which such Holder 
would have owned immediately following such action had such Note been 
converted immediately prior thereto. An adjustment made pursuant to this 
Subsection shall become effective immediately after the record date in the 
case of a dividend or distribution and shall become effective immediately 
after the effective date in the case of a subdivision, combination or 
reclassification.

     Section 8.5      Adjustment for Mergers.  In case of any consolidation 
or merger to which the Company is a party other than a merger or consolidation 
in which the Company is the continuing corporation, or in case of any sale or 
conveyance to another corporation of the property of the Company as an 
entirety or substantially as an entirety, or in the case of any statutory 
exchange of securities with another corporation (including any exchange 
effected in connection with a merger of a third corporation into the Company), 
there shall be no adjustment under Section 8.4 but the Holder shall have the 
right thereafter to convert such Note into the kind and amount of shares of 
stock and other securities and property which such Holder would have owned or 
have been entitled to receive immediately after such consolidation, merger, 
statutory exchange, sale or conveyance had such Note been converted 
immediately prior to the effective date of such consolidation, merger, 
statutory exchange, sale or conveyance and in any such case, if necessary, 
appropriate adjustment shall be made in the application of the provisions set 
forth in this Article with respect to the rights and interest thereafter of 
the Holder. The provisions of this Subsection shall similarly apply to 
successive consolidations, mergers, statutory exchanges, sales or conveyances.


ARTICLE IX.  REGISTRATION OF CONVERSION SHARES


     Section 9.1     Incidental Registration.  If, the Company shall determine 
or 
be required to register any shares of the Company's Common Stock (whether on 
behalf of itself or any other person) under the Securities Act of 1933 on 
Forms S-1, S-2, S-3, SB-1, or SB-2 (or if such forms are rescinded by the 
Securities and Exchange Commission (the "Commission") such forms as replace 
those forms), excluding any registration for the offering and sale of 
securities of the Company to its employees, it will notify all record Holders 
of Conversion Shares in order that they may request that all or a part of 
their Conversion Shares of Common Stock be included in the registration 
statement.  If requested by any Holder of Conversion Shares in writing within 
20 days after the Company's notice, the Company will, except as herein 
provided, include the requested number of Conversion Shares in such 
registration statement.  Any such request shall include the agreement of the 
Holder requesting the registration to execute and deliver the underwriting 
agreement, if any, to be executed and delivered in connection with such 
registration.  The Company may, however, decline to include all or a part of 
the requested number of shares in a registration statement pursuant to this 
section if it is advised by the investment banking firm, if any, managing the 
underwriting (or, in the case of a registration undertaken by the Company 
without underwriters, if it is determined by the Board of Directors of the 
Company) that such inclusion would adversely affect the offering of the shares 
to be covered by the proposed registration statement.

     Section 9.2     Registration Procedures.  The Company shall use its best 
efforts to file such post-effective amendments to any registration statement 
described herein as shall be necessary to keep it effective until six months 
after the effective date of the registration statement or the date on which 
all of the Conversion Shares of Holders covered thereunder shall have been 
sold, whichever is earlier.

     Section 9.3     Expenses.  The expenses of the registration of Holders' 
Conversion Shares (other than transfer taxes, underwriting commissions, and 
fees of Holders' counsel) shall be paid by the Company.

     Section 9.4     Conditions to Company's Obligation.  As a condition to 
the 
Company's obligation under this Article IX to cause a registration statement 
or amendment to be filed or shares to be included in a registration statement, 
each Holder shall provide such information and execute such documents as may 
reasonably be required in connection with such registration.  In addition, the 
Company shall not be required to include such shares in a registration 
statement if it shall have received opinions of its and the Holder's counsel 
to the effect that the proposed disposition of such shares may be effected 
without registration under the Act.

     Section 9.5     Special Definition.  For purposes of this Article IX. 
"Conversion Shares" shall mean the shares of Common Stock of the Company 
issuable upon conversion of the Notes and all shares of such Common Stock 
issued in exchange or substitution therefor, whether or not such securities 
(other than the Notes) have in fact been issued, and the stock or other 
securities of the Company issued in a stock split or reclassification of, or a 
stock dividend or other distribution on or in substitution or exchange for, or 
otherwise in connection with, any of the foregoing securities, or in a merger 
or consolidation involving the Company or a sale of all or substantially all 
of the Company's assets.  For purposes hereof, the record Holder of the Notes 
shall be treated as the record Holder of the related Common Stock then 
issuable upon the exercise thereof.  Nothing in this Section 9.5 shall, 
however, be deemed to require the Company to register the Notes, it being 
understood that the registration rights granted hereby relate only to shares 
of Common Stock of the Company and securities issued in substitution or 
exchange therefor.

     Section 9.6     Availability of Registration Rights.   The right to a 
registration pursuant hereto shall commence on the first date at which the 
Notes may be converted, and shall terminate at midnight on August 31, 2006.


      ARTICLE X.  EVENTS OF DEFAULT

     Section 10.1     Events of Default.  An "Event of Default" shall exist 
if any of the following occurs and is continuing:

     (a)     Default shall be made by the Company in a payment of principal on 
any Note, when and as the same shall become due and payable, at maturity 
(including upon acceleration), upon redemption, or otherwise; or

     (b)     Default shall be made by the Company in a payment of interest on 
any Note, when and as the same shall become due and payable, and such default 
shall continue for fifteen (15) calendar days after there has been given 
written notice of such default to the Company by the Holders of at least 25% 
in aggregate principal amount of the outstanding Notes; or

     (c)     Default shall be made in the performance or observance of any 
covenant, condition, undertaking or agreement contained in this Agreement or 
the Notes, and such default shall continue for thirty (30) calendar days after 
there has been given written notice of such default to the Company by the 
Holders of at least 25% in aggregate principal amount of the outstanding 
Notes.

     Section 10.2     Acceleration; Waiver of Default.

     (a)     In case any one or more of the Events of Default specified in 
Section 10.1 shall have happened and be continuing, the Holder or Holders of 
at least 25% in aggregate principal amount of the outstanding Notes shall have 
the right to accelerate payment of the entire principal of, and all interest 
accrued on, all such outstanding Notes, and, upon such acceleration, the Notes 
shall thereupon become forthwith due and payable, without any presentment, 
demand, protest or other notice of any kind, all of which are hereby expressly 
waived, and the Company shall forthwith pay to the Holder of the Note the 
entire outstanding principal of, and interest accrued on, such Note.

     (b)     If an Event of Default shall occur and be continuing, the Holder 
or Holders of a majority in aggregate principal amount of the outstanding 
Notes may proceed to protect and enforce the rights of the Holders either by 
suit, in equity and/or by action at law, or by other appropriate proceedings, 
whether for specific performance (to the extent permitted by applicable law or 
equitable principles) of any covenant or agreement contained in this Agreement 
or the Notes, or in aid of the exercise of any power granted in this Agreement 
or the Notes, or may proceed to enforce the payment of the Notes or to enforce 
any other legal or equitable right of the Holders of the Notes.

     (c)     The Holders of a majority in aggregate principal amount of 
outstanding Notes may waive an Event of Default resulting in acceleration of 
such Notes but only if all Events of Default have been remedied and all 
payments due, other than those due as a result of acceleration, have been 
made.

     (d)     No course of dealing on the part of the Holder of any Note or any 
delay or failure on the part of such Holder to exercise any right shall 
operate as a waiver of such right or otherwise prejudice such Holder's rights, 
powers and remedies.


  ARTICLE XI.  AMENDMENT AND WAIVER

     Any term, covenant, agreement or condition of this Agreement may be 
amended, or compliance therewith may be waived, if the Company shall have 
obtained the agreement or consent in writing of the Holders of at least a 
majority in aggregate principal amount of all outstanding Notes; provided, 
however, that no such amendment or waiver shall, without the consent of the 
Holder of each Note affected thereby, (i) change the stated maturity of the 
principal of, or the due date of any installment of interest on, any Note, 
(ii) reduce the principal of, or rate of interest on, any Note, (iii) change 
the place of payment where, or coin or currency in which any portion of the 
principal of, or interest on, any Note is payable, (iv) impair the right to 
institute suit for the enforcement of any such payment, (v) reduce the 
above-stated percentage of Holders of the outstanding Notes necessary to 
modify this Agreement, or (vi) modify the foregoing requirements or reduce the 
percentage of outstanding Notes necessary to effect such amendments or 
waivers.


       ARTICLE XII.   MISCELLANEOUS

     Section 12.1     Representations and Warranties of Note Purchasers.  
Each Note Purchaser hereby represents and warrants:

     (a)     The Securities being acquired by such Purchaser are for his or 
her 
own account for investment and not with a view of the resale or distribution 
there of, and he or she has no present intention of making any distribution or 
disposition of any of such Securities.  Purchaser understands that the 
Securities are being sold to him or her in a transaction which is exempt from 
the registration requirements of the Securities Act of 1933 (the "Act"), and 
that such Securities must be held and not resold unless they are subsequently 
registered under the Act or an exemption from such registration is available 
and the Securities shall contain a legend to the foregoing effect.

     (b)     He or she has received and carefully read the Memorandum and this 
Note Purchase Agreement and has not been furnished with any other offering 
materials or literature relating to the Company other than as stated herein.

     (c)      He or she has had a reasonable opportunity to ask questions of 
and 
receive answers from the Company concerning the Company and the Securities, 
and any such questions have been answered to his or her full satisfaction.  In 
addition, such Note Purchaser has had the opportunity to request additional 
information from the Company as described in the Memorandum under "Additional 
Information."  Any such requested additional information has been provided.

     (d)     He or she either (i) along with his or her representative, has 
such knowledge and expertise in financial and business matters that he or she 
is capable of evaluating the merits and risks involved in an investment in the 
Securities (Note Purchaser's representative must be specifically acknowledged 
as such for the purpose of a potential investment in the Securities), or (ii) 
qualifies as an "accredited investor" (as that term may be further defined 
under Regulation D promulgated under the Act) at the time of his or her 
purchase of the Notes. 

     (e)      He or she has adequate means of providing for his or her current 
needs and has no need for liquidity in this investment.  The Note Purchaser 
has no reason to anticipate any material change in his or her financial 
condition for the foreseeable future.  The Note Purchaser understands that he 
or she may be required to bear the economic risk of an investment in the 
Securities for an indefinite period because the Securities have not been 
registered under the Act, and, therefore, cannot be sold unless they are 
subsequently registered under the Act or an exemption from such registration 
is available.  Purchaser has been advised that Rule 144 under the Act permits 
the resale, subject to strict conditions, of limited amounts of "restricted 
securities" (as the Conversion Shares will be classified under Rule 144) after 
they have been held for two years.  Rule 144, among other things, requires 
that adequate current public information be available with respect to the 
Company.  Purchaser acknowledges that the Company is under no obligation to 
register the Securities under the Act, to become a reporting company under the 
Securities Exchange Act of 1934, or otherwise make public the financial and 
other information required to comply with the requirements of any exemptions 
from registration under the Act, except as otherwise set forth herein.

     (f)     He or she is aware that the purchase of the Notes is a 
speculative 
investment involving a high degree of risk and that there is no guarantee that 
the Note Purchaser will realize any gain from this investment, and that the 
Note Purchaser could lose the total amount of his or her investment.   He or 
she is financially able to bear the economic risk of the investment in the 
Securities, including a total loss of such investment. The Note Purchaser has 
carefully considered the risk factors set forth in the Memorandum.

     (g)     Each Note Purchaser understands that no federal or state agency 
has made any finding or determination regarding the fairness of the Offering, 
nor any recommendation or endorsement of the Offering.

     (h)     Except as set forth in this Note Purchase Agreement, no 
representations or warranties have been made to the Note Purchaser by the 
Company, and in entering into this transaction, the Note Purchaser is not 
relying upon any information other than that referred to herein.  No person 
has made any representation or warranties as to the accuracy or completeness 
of the information contained in the Memorandum.  Neither the Company, nor any 
other person acting on its behalf has offered or sold the Notes to him or her 
by any form of general solicitation or general advertising.

     (i)     Purchaser understands that the Securities are being offered and 
sold to him or her in reliance on specific exemptions from the registration 
requirements of federal and state securities laws and that the Company is 
relying upon the truth and accuracy of the representations, warranties, 
agreements, acknowledgments, and understandings of the Note Purchaser set 
forth herein in order to determine the applicability of such exemptions and 
the suitability of the Note Purchaser to acquire the Securities. 

     (j)     The address set forth below is the Note Purchaser's residence, 
and 
he or she has no present intention of becoming a resident of any other state 
or jurisdiction.

     (k)      The Note Purchaser acknowledges that the Notes and the 
certificate 
for Conversion Shares issued to him or her will bear the legend set forth on 
page A-4 hereof, and appropriate stop transfer instructions will be noted in 
the Company's stock records.

     (l)     The foregoing representations and warranties are true and 
accurate 
as of the date hereof and shall be true and accurate as of the date of 
delivery of the Note Purchase Price to the Company, and shall survive such 
delivery. 

     (m)     The Note Purchaser acknowledges that he or she understands the 
meaning and legal consequences of the representations and warranties contained 
in this Note Purchase Agreement, and he or she hereby agrees to indemnify and 
hold harmless the Company and each officer and director thereof from and 
against any and all loss, damage, or liability due to or arising out of a 
breach of any representation or warranty of the Note Purchaser contained in 
this Note Purchase Agreement.

     Section 12.2     Assignment and Transfer.  The Note Purchaser and any 
Holder of a Note may transfer Notes, in whole or in part. to another person 
and may, in connection with such transfer, assign its rights in whole or in 
part under this Agreement, provided that such transfer complies with 
applicable federal and state securities laws. The Company agrees to execute 
and deliver such instruments, documents, and certificates as the Note 
Purchaser, a Holder or any such transferee may reasonably request in order to 
document the transfer in whole or in part of rights hereunder, which 
instruments, documents and certificates shall be in form and substance 
reasonably satisfactory to counsel for the Note Purchaser or Holder or such 
transferee.  Other than as provided in Section 6.3 hereof, the Company map not 
assign its rights, or effect an assumption of its obligations hereunder, in 
whole or in part, without the prior written consent of all of the Holders of 
the Notes.

     Section 12.3     Survival of Agreements.  All covenants, 
representations and warranties contained herein or in the Notes, or made in 
any document given or supplied in connection herewith, shall survive the 
execution and delivery of this Agreement, the issuance, sale and delivery of 
the Notes and payment therefor, any disposition thereof by the Holders 
thereof, and any investigation at any time made by such Holder on its behalf.  
All statements contained in any report, memorandum, certificate or other 
instrument delivered in connection with the transactions contemplated hereby 
or pursuant hereto shall constitute representations and warranties as of the 
date of delivery of such report, memorandum, certificate, or other instrument.

     Section 12.4     Notices.  Unless otherwise specifically provided 
herein, all communications under this Agreement or the Notes shall be in 
writing and shall be deemed to have been duly given (i) on the date of service 
if served personally on the party to whom notice is to be given, (ii) on the 
day of transmission if sent by facsimile transmission to the telecopy number 
given below, and telephonic confirmation of receipt is obtained promptly after 
completion of transmission, (iii) on the day after delivery to Federal Express 
or similar overnight courier, or (iv) on the fifth day after mailing, if 
mailed to the party to whom notice is to be given, by first class mail, 
registered or certified, postage prepaid, and properly addressed, return 
receipt requested, to the party as follows:

     
     If to the Note Purchasers:          To the address of each Note 
Purchaser then reflected on the Note 
Register maintained by the Company.

Any party hereto, or Holder of a Note, may change its address for purposes of 
this Section 12.4 by giving the other party written notice of the new address 
in the manner set forth above.

     Section 12.5     Binding Effect.  All the terms of this Agreement shall 
be binding upon, and inure to the benefit of and be enforceable by the 
respective successors and assigns of the parties hereto. 

     Section 12.6     Entire Agreement.  This Agreement (including the 
Exhibits and Schedules which form a part hereof) constitutes the entire 
agreement between the parties hereto and supersedes all prior agreements and 
understandings, oral and written, between the parties with respect to the 
subject matter hereof.

     Section 12.7     Modification and Waiver.  Neither any failure nor any 
delay on the part of the Company, any Note Purchaser or the Holder of any Note 
in exercising any right, power or privilege hereunder or under the Notes shall 
operate as a waiver thereof, nor shall a single or partial exercise thereof 
preclude any other or future exercise, or the exercise of any other right, 
power or privilege.

     Section 12.8     Severability.  Every provision in this Agreement is 
intended to be severable. If any term or provision hereof is illegal or 
invalid for any reason whatsoever, such illegality or invalidity shall not 
affect the validity of the remainder hereof.

     Section 12.9     Governing Law; Venue.  This Agreement and the Notes 
shall be governed by and construed under Florida law, without reference to 
principles of choice of law thereunder.  The Company and each Note Purchaser 
hereby submits to the jurisdiction and venue of the United States District 
Court for the Northern District of Florida or the Circuit Court, Alachua

of the United States of America as at the time of payment is legal tender for 
payment of public and private debts; provided, however, that at the option of 
the Company payment of interest may be made (subject to collection) by check 
mailed to the address of the person entitled thereto as such address shall 
appear on this Note Register.

     This Note is one of a duly authorized issue of Notes of the Company 
designated as its 10% Convertible Unsecured Notes due 2001 (herein called the 
"Notes"), issued and to be issued under a Note Purchase Agreement dated as of 
September 13, 1996 (herein called the "Note Purchase Agreement"), between the 
Company and initial Note Purchasers, to which Note Purchase Agreement 
reference is hereby made for a statement of the respective rights thereunder 
of the Company and the Holders of the Notes, and the terms upon which the 
Notes are, and are to be, delivered.

     The indebtedness of the Company evidenced by the Notes, including the 
principal thereof and interest thereon, is an unsecured general obligation of 
the Company and will rank pari passu with all other unsecured general 
obligations of the Company.  Each Holder of a Note, by acceptance hereof, 
agrees to and shall be bound by the provisions of the Note Purchase Agreement.

to redeem the Notes, in whole at any time or in part from time to time, upon 
written notice to the Note Purchasers given not less than 60 days prior to the 
date proposed for redemption, at the redemption price of 90% of the principal 
amount, plus accrued and unpaid interest, if any, thereon to the date fixed 
for redemption ("Redemption Date").

Holders of Notes to be redeemed by mailing a notice of such redemption not 
less than 10 days prior to the accepted Redemption Date at their addresses as

bear interest from and after such Redemption Date.

     Interest installments whose stated maturity is on the Redemption Date 
will be payable to the Holders of such Notes, or one or more Predecessor 
Notes, of record at the close of business on the relevant record date for such 
interest installment, all as provided in the Note Purchase Agreement. In the 
event of redemption of this Note in part only, a new Note or Notes for the 
unredeemed portion hereof shall be issued in the name of the Holder hereof 
upon the cancellation hereof.

      This Note is convertible into shares of Common Stock, $.01 par value, of 
the Company, at a conversion price of $4.20 per share, in the manner set forth 
in the Note Purchase Agreement.

     If an Event of Default as defined in the Note Purchase Agreement shall 
occur and be continuing, the principal of all the Notes may be declared due 
and payable in the manner and with the effect provided in the Note Purchase 
Agreement.  The Note Purchase Agreement provides that such declaration and its 
consequences may, in certain events, be annulled by the Holders of a majority 
in principal amount of the Notes outstanding.

     The Note Purchase Agreement permits, with certain exceptions as therein 
provided, the amendment thereof and the modification of the rights and 
obligations of the Company and the rights of the Holders of the Notes under 
the Note Purchase Agreement at any time by the Company with the consent of the 
Holders of a majority in aggregate principal amount of the Notes at the time 
outstanding. The Note Purchase Agreement also contains provisions permitting 
the Holders of a majority in aggregate principal amount of the Notes at the 
time outstanding, on behalf of the Holders of all the Notes, to waive 
compliance by the Company with certain provisions of the Note Purchase 
Agreement and certain past defaults under the Note Purchase Agreement and 
their consequences. Any such consent or waiver by the Holder of this Note 
shall be conclusive and binding upon such Holder and upon all future Holders 
of this Note and of any Note issued upon the registration of transfer hereof 
or in exchange therefor or in lieu hereof, whether or not notation of such 
consent or waiver is made upon this Note.
      No reference herein to the Note Purchase Agreement and no provisions of 
this Note or of the Note Purchase Agreement shall alter or impair the 
obligation of the Company, which is absolute and unconditional, to pay the 
principal of and interest on this Note at the times, places and rate, and in 
the coin or currency, herein prescribed.

      As provided in the Note Purchase Agreement and subject to certain 
limitations therein set forth, this Note is transferable on the Note Register 
of the Company, upon surrender of this Note for registration of transfer at 
the office or agency of the Company to be maintained for that purpose in 
Alachua, Florida, or at such other office or agency as may be established by 
the Company for such purpose pursuant to the Note Purchase Agreement 
(initially the principal executive office of the Company in Alachua, Florida), 
duly endorsed by, or accompanied by a written instrument of transfer in form 
satisfactory to the Company duly executed by, the Holder hereof or his 
attorney duly authorized in writing, and thereupon one or more new Notes, of 
authorized denominations and for the same aggregate principal amount, will be 
issued to the designated transferee or transferees.

     The Notes are issuable only in registered form, without coupons, in 
denominations of $100, or greater multiples of $100.  Notes are exchangeable 
for a like aggregate principal amount of Notes of a different authorized 
denomination, as requested by the Holder surrendering the same.

     No service charge shall be made for any such transfer or exchange, but 
the Company may require payment of a sum sufficient to cover any tax or other 
governmental charge payable in connection therewith.

     Each Holder of a Note covenants and agrees by such Holder's acceptance 
thereof to comply with and be bound by the foregoing provisions.

     Certain terms used in this Note which are defined in the Note Purchase 
Agreement have the meanings set forth therein.

     The Company and any agent of the Company may treat the person in whose 
name this Note is registered as the owner hereof for all purposes, and neither 
the Company nor any such agent shall be affected by notice to the contrary.

     IN WITNESS WHEREOF, the Company has caused this Note to be signed in its 
name by the signature of its Chairman, President, or one of its Vice 
Presidents and its corporate seal to be impressed or imprinted hereon, 
attested by the signature of its Secretary or one of its Assistant

      INCUBATOR LICENSE AGREEMENT

 
THIS AGREEMENT, made this 26th  day of June 1995, between Ixion 
Biotechnology, Inc. ("Licensee") and the University of Florida Research 
Foundation, Inc., a Florida not for profit corporation ("UFRFI") in 
Gainesville, Florida.

WHEREAS, the University of Florida ("University") has established the 
Biotechnology Development Institute ("BDI") which seeks to encourage the 
development of early-stage companies whose technology relates to the molecular 
life sciences by providing  incubator  resources which will foster that 
 development (the "Incubator Program");  and
 
         WHEREAS, the BDI Building has been constructed at the Progress Park 
in Alachua, Florida, to provide facilities for the Incubator Program; and

WHEREAS, UFRFI has agreed to manage certain activities of the Incubator 
Program, including licensing and managing space in the BDI building, and other 
services as more particularly described herein; and
 
WHEREAS, Licensee has submitted an application  for admission to the BDI 
Incubator Program and  has submitted or is developing a business  plan in 
support of that application; and

WHEREAS, UFRFI, upon review of Licensee's application and supporting 
documentation, has accepted Licensee's application for participation in the 
BDI Incubator Program; and

WHEREAS, Licensee is desirous of being the recipient of resources to be 
made available to the participants  in  the BDI Incubator Program;

NOW, THEREFORE, in consideration of the mutual covenants and agreements 
in this Agreement, the parties agree as follows:

1.   License Grant.  UFRFI  grants to Licensee and Licensee hereby 
accepts a license to use the  space or spaces  located within the  BDI 
Building, the exact location and area allowances of which are as indicated in 
Attachment A (the "Licensed Space"). UFRFI shall also make available the 
following resources and facilities:


(a) Shared Facilities.    UFRFI will provide a centralized 
reception and administrative support suite and  limited secretarial services. 
 Other services and facilities will  include access to centralized mail 
handling, certain library and reference materials, a copying machine, a fax 
machine, and limited transportation between the BDI Building and the 
University campus.  In addition, the BDI Building will contain a central 
instrumentation lab for common equipment usage, common use cold rooms, 
autoclaves, and dark room, a 600 sq. ft. greenhouse, support facilities for 
media preparation, small-scale fermentation experiments, and glassware 
washing.  Such services and facilities will be made available to Licensee on a 
shared basis with other occupants of the BDI Building and others, and, as 
such, Licensee understands that UFRFI will make such services available on a 
reasonable, best efforts basis, as determined at the sole discretion of the 
BDI's Incubator Manager.  The "Incubator Manager" is defined as the Assistant 
Director for R&D of the University's Biotechnology Program, or his or her 
designee.  

(b)  "If Available" Shared Facilities.    UFRFI will provide 
Licensee on an "if available" basis the use of a conference room within the 
BDI Building, together with certain audio visual equipment. On-campus meeting 
and conference rooms may be requested through the Incubator Manager.

(c) Communications Connections.  UFRFI shall provide wiring and 
jacks for two (2) telephones and two (2) computer and network hook-ups within 
each office or lab in the Licensed Space.  Licensee shall pay any additional 
costs associated with telephone, computer, or network services, including, but 
not limited to, monthly service charges, service initiation charges, voice  
mail charges, long distance charges, and e-mail or connect time charges.  Any 
replacement or upgrading of equipment or service shall be at the expense of 
Licensee and only with the prior written approval of the Incubator Manager.

(d)  Utilities. UFRFI shall provide Licensee with electric, gas, 
water, analytical grade deionized water, and sewer service for seven days per 
week of normal office or laboratory use.  BDI shall also supply normal waste 
disposal during business days.  Normal and reasonable janitorial service shall 
be provided by UFRFI.  If Licensee makes excessive use of the facilities as 
determined by the Incubator Manager in his or her sole discretion, the costs 
of such excessive use shall be borne by Licensee as additional cash license 
fees as described below.

(e) Lab and Office Equipment. Upon request of Licensee, UFRFI 
shall use its best efforts to provide for use within Licensed Space the lab 
and office equipment set forth on Attachment A.   Any changes in carpet, 
installed equipment, or furnishings, or any structural changes in the Licensed 
Space shall be implemented only with the prior written approval of the 
Incubator Manager, and at the exclusive expense of Licensee.
 
(f)  Core Laboratories and other Resources. UFRFI will use its 
best efforts, but does not guarantee, to provide Licensee with access to 
certain Biotechnology Program  resources upon request by Licensee,  including 
access to the Biotechnology Program Core Laboratory Services, and 
transportation for samples and reagents between campus-based laboratories and 
facilities and the BDI Building.  Licensee may, at UFRFI's discretion, have 
access to disclosure, patent, or technology transfer training.  Payment of 
service fees relating to such resources, if any, shall be the sole 
responsibility of Licensee. 

(g) Damage to Facilities.  In the event that any licensed 
facilities, equipment, or any other UFRFI or University property is damaged or 
destroyed through use, misuse, or negligence by Licensee, UFRFI may make the 
required repairs or replacement of damaged property and shall provide Licensee 
with an invoice representing the loss to UFRFI or the University (whether 
replaced or repaired or otherwise), said invoice to be due and payable by 
Licensee in accordance with its terms.  In the event that normal maintenance 
is required for said facilities, equipment, or  UFRFI or University property, 
Licensee shall notify the Incubator Manager, who is the sole person authorized 
to arrange for such service.  The cost for any unauthorized repairs ordered by 
Licensee shall be borne exclusively by Licensee.

2.  Scheduling of Use of University Campus Facilities.  Licensee shall 
schedule the use of any University campus facilities only through the 
Incubator Manager.

3.  License Fees; Term. The term of this Agreement and Licensee's 
obligation to pay a license fee (consisting of both a monthly cash payment and 
warrants to purchase Licensee's common stock shares) are as provided below.   
Additional warrants may be required if this Agreement is renewed as provided 
in this Section 3.  

(a) License Fees.  Cash payments shall commence on the first day 
of August, 1995  , (the "Effective Date"), and thereafter the license fee 
shall be paid in equal monthly installments on the first day of each month 
during the term, in advance, to the UFRFI at its offices at 109 Grinter Hall, 
Gainesville, Florida 32611-2037, unless UFRFI designates another place.  The 
license fee shall be paid without abatement, deduction, or set off for any 
reason.  In the event that UFRFI has not completed renovations to the Licensed 
Space, if any, as agreed upon for Licensee's research activities, the 
Effective Date shall be that date on which UFRFI and Licensee agree that UFRFI 
has completed the renovations agreed upon.    Any portion of the Licensed 
Space or other space in the BDI Building that is occupied by Licensee prior to 
the Effective Date shall be subject to a monthly fee equivalent to an annual 
rate of $10.00 per square foot, payable monthly and commencing on the date of 
such occupancy.

The cash license fee during the term of this license shall be 
payable by Licensee in equal monthly installments, on or before the first day 
of each month and shall be as follows:

Initial Term:

From August 1, 1995, to July 31, 1996,  $1,065.00 per month (of which 
$792.50 shall be paid in cash and $272.50 shall be deemed paid pursuant to 
Attachment F).

Renewal Terms:

From August 1, 1996, to July 31, 1997,  $1,171.50 per month (of which 
$871.75 shall be paid in cash and $299.75 shall be deemed paid pursuant to 
Attachment F).


From August 1, 1997, to July 31, 1998,  $1,278.00 per month (of which 
$951.00 shall be paid in cash and $327.00 shall be deemed paid pursuant to 
Attachment F).

(b) Term.  The initial term of the license shall be for 12 months 
following the commencement of the term as noted below and shall terminate on 
July 31, 1996, or on the last day of the month which is 12 months after the 
Effective Date, whichever is later.  Licensee shall have the option of two 
additional one-year renewal terms, provided written notice of the exercise of 
said option is furnished to UFRFI at least 60 days prior to the expiration of 
the current term.   Licensee's right to exercise such options is subject to 
satisfactory progress on meeting its R&D milestones and business plan 
objectives, such progress to be determined in the sole discretion of BDI after 
reasonable consultation with Licensee.  In the event this Agreement is 
extended, all of the terms and conditions contained herein shall apply to the 
renewal terms.

(c) Additional License Fees.  Unless otherwise agreed to, the cost 
of any services or resources provided by BDI or the University not indicated 
in Section 1 above shall be borne by Licensee.  Licensee shall be billed 
separately for said additional services or resources as additional cash 
license fees, payment for which shall be due and payable in accordance with 
the terms of the invoice therefor.

4.  Warrants.  Licensee intends to issue a Warrant to UFRFI to purchase 
shares of Licensee's common stock in further consideration for UFRFI's 
entering into this Agreement, and, except as provided in Section 5 herein, 
such Warrant shall remain in full force and effect without regard to whether 
this Agreement is terminated by either party for any reason.

(a) Warrant for Initial Term.  As set forth in Section 3 above, 
and upon the terms and conditions set forth herein, as a part of the license 
fee, Licensee shall grant to UFRFI a Warrant to purchase shares of Licensee's 
common stock, in accordance with the provisions of Attachment B. 
(b) Additional Warrants.  As a condition of renewal of this 
license for additional terms of one year beyond the initial term of 12 months, 
Licensee shall grant to UFRFI additional warrants to purchase  shares of 
Licensee's common stock for each renewal term.  The number of shares, term, 
and warrant exercise price of such Warrants will be determined by good faith 
negotiation prior to the commencement of renewal terms.

(c)   Anti-dilution, Term,  and Other Provisions.  Other terms of 
the Warrant shall be as set forth in the Warrant Agreement in Attachment B.   
  

5.  Termination.  The facilities, equipment, and Licensed Space licensed 
hereunder are licensed for the purpose of furthering Licensee's business 
objectives as approved by UFRFI.  Pertinent portions of Licensee's business 
plan, including its business objectives and financial progress reports are 
attached as Attachment C. 

(a) Not a Lease.  The parties understand that this Agreement 
constitutes a license, not a lease, and that the relationship of the parties 
hereunder is that of licensor and licensee, and not that of landlord and 
tenant.  As such, UFRFI reserves the right to change space assignments or to 
terminate this Agreement by written notice if the assigned space does not 
function as a place of business for more than one week, or if Licensee in 
UFRFI's sole discretion no longer meets the criteria for participation in the 
Incubator Program.  Notwithstanding Section 15 below, if UFRFI has reason to 
believe at any time that Licensee is no longer following its business plan as 
approved by UFRFI, UFRFI, in its sole discretion, may review Licensee's 
status.  If, in UFRFI's sole discretion, Licensee's current status is not in 
material accord with its business plan, UFRFI may terminate this Agreement.

(b) Default; Notice of Termination.  Should either party be in 
default in connection with any material terms or conditions stated within this 
Agreement, then the other party shall have the right to terminate this 
Agreement upon ten business days' written notice, if the other party does not 
correct such situation within the said ten day period.  Further, either party 
may terminate this Agreement, with or without cause, upon 60 days' written 
notice. This Section 5 does not relieve either party of any outstanding 
obligations incurred pursuant to this Agreement.  

(c)   Consequences of Certain Terminations.  If this Agreement is 
terminated by BDI, through no fault of Licensee, within one year of its 
Effective Date, the number of Licensee's shares of stock which UFRFI is 
entitled to purchase per paragraph 4 during the initial term shall be reduced 
on a pro rata basis.

6.  Indemnification.  Licensee shall at all times during the term of 
this Agreement and thereafter, indemnify, defend, and hold UFRFI and the 
University, their trustees, officers, employees, and affiliates (the 
"Indemnities"), harmless against all claims and expenses, including legal 
expenses and reasonable attorneys' fees, whether arising from a third party 
claim or resulting from UFRFI's enforcing this indemnification clause against 
Licensee, or arising out of the death of or injury to any person or persons or 
out of any damage to property and against any other claim, proceeding, demand, 
expense, or liability of any kind whatsoever resulting from the Licensee's 
occupancy of the Licensed Space, the use of any University services or 
resources, arising from any right or obligation of Licensee hereunder, or 
arising out of Licensee's business plan, or research involving, without 
limitation,  the use of animals, human subjects, or biohazardous materials.  
This indemnification shall not apply to any liability, damage, loss, or 
expense to the extent that it is attributable to the negligence or intentional 
wrongdoing of the Indemnities.
Licensee shall, at its own expense, provide attorneys reasonably acceptable to 
UFRFI to defend against any actions brought or filed against any party 
indemnified hereunder with respect to the subject of indemnity contained 
herein, whether such actions are rightfully brought.
7.   Insurance.  During the term of this Agreement, Licensee shall, at 
its sole cost and expense, procure and maintain policies of comprehensive 
general liability insurance naming the Indemnities as additional insureds. 

(a) Comprehensive General Liability.  The comprehensive general 
liability insurance shall provide broad form contractual liability coverage 
for Licensee's indemnification under this Section 6 in the following minimum 
amounts: 

(i)  comprehensive liability (personal injury, including death): 
$1,000,000, per claim and $5,000,000 per occurrence; and 

(ii) property damage: $1,000,000 per claim and $5,000,000 per 
occurrence.

(b) Self-Insurance.  If Licensee elects to self-insure, such self-
insurance program must be acceptable to UFRFI.  

(c) Other Insurance.  Licensee shall obtain and keep in force all 
worker's compensation insurance required under the laws of the State of 
Florida, and such other insurance as may be necessary to protect Indemnities 
against any other liability of person or property arising hereunder by 
operations of law, whether such law is now in force or is adopted subsequent 
to the Effective Date.

(d) Cancellation; Replacement Insurance.  Licensee shall provide 
UFRFI with written evidence of such insurance upon request, and shall provide 
UFRFI with written notice at least 45 days prior to the cancellation, non-
renewal, or material change in such comprehensive general liability insurance; 
if Licensee does not obtain replacement insurance providing comparable 
coverage within such 45 day period or provide self-insurance satisfactory to 
UFRFI, UFRFI shall have the right to terminate this Agreement.

(e) Assumption of Risk.  Each party assumes any and all risks of 
personal injury and property damage attributable to the negligent acts or 
omissions of that party and the officers, employees and agents thereof. 

(f) Non-exclusive Remedies.  Nothing contained herein shall be 
construed or interpreted as denying to either party any remedy or defense 
available to such party under the laws of the State of Florida; the consent of 
the State of Florida.

8.   Destruction of Space.  If the Licensed Space is totally destroyed 
(or so substantially damaged as to be unhabitable) by storm, fire, earthquake, 
or other casualty, this Agreement shall terminate as of the date of such 
destruction or damage, and license fees shall be accounted for as between 
UFRFI and Licensee as of that date.  If the Licensed Space is damaged but not 
rendered wholly unhabitable by any such casualty or casualties, license fees 
shall abate in such proportion as the use of the Licensed Space has been 
destroyed until UFRFI has restored the Licensed Space to substantially the 
same condition as before damage, whereupon full license fees shall commence.  
Nothing contained herein shall require UFRFI to make such restoration, 
however, if not deemed advisable in its judgment.  UFRFI shall make its 
intentions to restore or not to restore said Licensed Space to original 
condition known to Licensee in writing, within ninety (90) days of such 
occurrence.  If UFRFI decides against such reconstruction or fails to provide 
such notice, Licensee may, at its option, cancel this Agreement.

9.  Maintenance; Survey.  The Licensed Space shall be maintained in its 
original condition to the satisfaction of UFRFI, normal wear and tear 
excepted.  Prior to the Effective Date, a joint survey of the Licensed Space 
and equipment, indicating its exact condition, shall be made by 
representatives of both Licensee and UFRFI.  A written report of said survey 
shall be attached hereto and be made also upon termination of this Agreement. 
 In the event that the facilities incur any loss or damage, Licensee shall 
return the Licensed Space to its original condition to the satisfaction of 
UFRFI.  Otherwise, UFRFI shall make the required repairs or replacement of 
damaged property, and shall provide Licensee with an invoice due and payable 
in accordance with its terms.  Licensee, under this Section, is deemed to have 
accepted the Licensed Space in the condition existing on the Effective Date.  
Licensee is not liable for losses or damage to the License Space, furnishings, 
or equipment due to the sole negligence of UFRFI or the University.

10.  Security Deposit.  Licensee shall pay to UFRFI a sum equal to one 
month's cash license fee (as provided in Section 3 hereof) as further 
consideration for this Agreement.  The aforesaid sum is held by UFRFI as a 
non-interest bearing security for the full, faithful, and punctual performance 
by Licensee of the terms, covenants, and conditions of this Agreement.  

(a) Application of Security.  If, at any time, Licensee fails to 
fully, faithfully, and punctually perform any of the terms, covenants, and 
conditions contained herein, then UFRFI may apply any part or the whole of 
said security to indemnify UFRFI for any damage it may have suffered or will 
suffer because of such failure to perform by the Licensee; and UFRFI shall in 
no way be precluded from recovering in addition to the said security, any 
other damages or expenses that UFRFI may suffer by reason of any violation by 
Licensee of Licensee's terms, covenants, and conditions contained herein.

(b) Return of Security.  If this Agreement is terminated prior to 
the expiration of the term hereof by agreement of the parties, or in 
accordance with the terms of this license, and the Licensee has fully, 
faithfully, and punctually performed all of the Licensee's obligations 
hereunder up to the date of the termination, then the security deposit 
described herein shall be returned by UFRFI to Licensee.

11.  Interruption of Business.  Except as specified in Section 8, 
neither the University nor UFRFI shall be responsible to Licensee for any 
damages or inconvenience caused by interruption of business or inability to 
occupy the Licensed Space for any reason whatsoever, providing that, Licensee 
shall be credited with the cash license fee on a pro rata basis for any 
working day period, if the business interruption is due to circumstances 
caused by UFRFI that are not in the normal course of business or that are not 
a part of normal operating procedures at the BDI Building.

12. No Assignment.  This Agreement is not assignable without the prior 
written consent of UFRFI, and any attempt to do so shall be void.

13.  Qualification for Incubator; Non-Interference; Animal or Human 
Research; Toxic Materials.  Licensee's admittance to the Incubator Program is 
based, in part, on UFRFI's review of Licensee's business concept, objectives, 
and plans.  Use of the Licensed Space and other facilities, furnishings, 
equipment, and services made available to Licensee by UFRFI or the University 
shall be in furtherance of Licensee's business concept, objectives, and plans, 
and shall not be in furtherance of any illicit or illegal purposes, or 
purposes not consistent with Licensee's business concept, objectives, and 
plans.  Licensee's use of the Licensed Space and the equipment, furnishings, 
and services available under this Agreement shall not interfere, in any 
manner, with use by other licensees or occupants of nearby facilities and 
equipment.  Research involving the use of animals, human subjects, or the use 
of hazardous or toxic materials by Licensee is not permitted unless consented 
to in writing by BDI, and then only in the manner prescribed by UFRFI.  UFRFI 
reserves the right to approve in its sole discretion Licensee's use of the 
Licensed Space and available equipment and services.  Approval of the effort 
outlined in this Agreement is acknowledged by the signing of this Agreement by 
UFRFI.

14.  Compliance with University and UFRFI Policies; Requirements.  
Licensee shall comply with all applicable UFRFI or University rules or 
policies, including policies relating to human and animal subjects, 
recombinant DNA/RNA practices, biohazards, and radiation safety, as well as 
federal, state, or local laws, ordinances, codes, rules, permits, licensing 
conditions, and regulations, including any amendments thereto (collectively, 
the "Requirements"), in its use of the Licensed Space, and shall procure, at 
its expense, any licenses, permits, insurance, and government approvals 
necessary to the operation of its business. 

(a) Certain Federal Statutes.   "Hazardous substance" as used 
herein includes any "hazardous substance" as defined by the Comprehensive 
Environmental Response, Compensation, and Liability Act, 42 U.S.C. s 9601, et 
seq., including any amendments thereto ("CERCLA"), any substance, waste, or 
other material considered hazardous, dangerous, or toxic under any of the 
Requirements, petroleum and petroleum products, and natural gas.  "Release" as 
used herein means any intentional or unintentional spilling, pumping, 
emitting, emptying, discharging, escaping, leading, dumping, disposing, or 
abandonment of any hazardous substance.  Licensee shall comply with all 
Requirements governing the discharge, release, emission, or disposal of any 
hazardous substance and prescribing methods for  or other limitations on 
storing, handling, or otherwise managing hazardous substances including, but 
not limited to, the then-current versions of the following federal statutes, 
any Florida analogs, and the regulations implementing them: the Resource 
Conservation and Recovery Act (42 U.S.C. s 6901, et seq.); CERCLA; the Clean 
Water Act (33 U.S.C. s 1251, et seq.); the Clean Air Act (42 U.S.C. S 7401, et 
seq.); and the Toxic Substances Control Act (15 U.S.C. S 2601, et seq.).  
Licensee shall comply with all requirements of the Animal Welfare Act (7 
U.S.C. S 2131, et seq.) as the same may be amended, and all similar federal, 
state, and local laws, codes, ordinances, and regulations.

(b) Hazardous Substances; Disposal.  Licensee covenants and agrees 
that it will not use or allow the Licensed Space to be used for the storage, 
use, treatment, disposal, or other handling of any hazardous substance without 
the prior written consent of UFRFI.  Attached to the License as Attachment C 
is a list prepared by Licensee identifying the hazardous substances which 
Licensee intends to use and store in the premises, and setting forth the 
quantity, use, and location thereof.  BDI hereby permits Licensee to use and 
store the hazardous substances set forth on Attachment D within the Licensed 
Space, provided that Licensee complies in all respects with the Requirements 
and this Section and that such hazardous substances are not disposed of in the 
sanitary sewer system of the BDI Building unless the Requirements permit and 
the BDI has consented to such method of disposal in writing, having determined 
in UFRFI's sole and absolute discretion that such disposal will not harm the 
sanitary sewer piping.  Licensee shall request in writing UFRFI's written 
approval before any additional hazardous substance use, handling, treatment, 
storage, or disposal in the Licensed Space is undertaken.  Such request shall 
set forth a description of the hazardous substance involved, the maximum 
quantity to be present in the Licensed Space at any time, its location within 
the Licensed Space, and its use in Licensee's business.

(c) Violations.  Licensee shall take all steps necessary to remedy 
any violation of any Requirements by the Licensee whether or not a citation or 
other notice of violation has been issued by a governmental authority.  
Licensee shall at its own expense, promptly contain and remediate any release 
of hazardous substances arising from or related to Licensee's hazardous 
substance activity to the Licensed Space, the BDI Building, or the environment 
and remediate any resultant damage to the property, persons, or the 
environment. 

(d) Environmental Inspections.  UFRFI reserves the right to 
periodically conduct an environmental and safety inspection of the Licensed 
Space and areas beyond such space, where necessary, such as the HVAC system 
and the laboratory exhaust venting system.  The scope of such inspection may 
include, but not be limited to, having the fume hoods tested and inspected.  
Licensee shall give prompt written notice to UFRFI of any release of any 
hazardous substance in the Licensed Space, the BDI Building or the environment 
not made in conformance with the Requirements, including a description of 
remediation measures and any resulting damage to persons, property, or the 
environment.  Licensee shall upon expiration or termination of this License, 
surrender the Licensed Space to UFRFI free from the presence and contamination 
of any hazardous substance.  Following any breach by Licensee of the 
Requirements of this Section, or any reasonable safety or environmental 
concern by UFRFI, UFRFI may withdraw its consent to Licensee's hazardous 
substance activity (or any portion thereof) by written notice to Licensee.  
Licensee shall terminate its hazardous substance activity immediately upon 
notice and remove all hazardous substances from the Licensed Space within 15 
days from the date of such notice unless such breach or concern is promptly 
addressed and corrected by Licensee to UFRFI's sole satisfaction.  Licensee 
shall indemnify, hold harmless and (at UFRFI's option) defend the University 
or UFRFI, their agents and employees, from and against all claims, actions, 
losses, costs and expenses (including attorneys' and other professional fees), 
judgments, settlement payments, and, whether or not reduced to final judgment, 
all liabilities, damages, or fines paid, incurred, or suffered by such parties 
in connection with loss of life, personal injury, or damage to property of the 
environment arising, directly or indirectly, wholly or in part from any 
conduct, activity, act, omission, or operation involving the use, handling, 
generation, treatment, storage, disposal, other management or release of any 
hazardous substance at, from, or to the Licensed Space, whether or not 
Licensee has acted negligently with respect to such hazardous substance.  
Licensee's obligations and liabilities hereunder shall survive the expiration 
or other termination of this License

15. UFRFI's Control of Facilities.  Notwithstanding anything to the 
contrary herein, UFRFI reserves the right at all times to control all 
facilities licensed hereunder, and to enforce all applicable necessary laws, 
rules, and regulations.

16.  Business Plan and R&D Review.  At the request of UFRFI, but not 
more frequently than at six month intervals, Licensee agrees to review its 
current and prospective business plan and R&D program status with UFRFI.  
Progress may be monitored in relation to the previous most recent plans which 
have been reviewed and approved by both Licensee and UFRFI.  If, in UFRFI's 
sole discretion, the Licensee's current status is not sufficiently in accord 
with the most recent previously reviewed plans, UFRFI may give written notice 
of default in accordance with Section 5 above.

17.  Locks.  UFRFI will install all locks attached to the Licensed Space 
and provide two keys for each lock to Licensee.  UFRFI, through its agent , 
BDI,  will have keys to all locks, and may enter the Licensed Space at 
reasonable times, for inspection, maintenance or repair, or for any other 
necessary reason.  Entry for other than normal maintenance and inspection 
activities shall be preceded by appropriate notice to Licensee.  In the event 
of an emergency, notice will be given at the first reasonable opportunity, 
even after the fact.

18.  Right to Remove Property.  Unless in default of contract, Licensee 
shall have the right to remove any equipment, goods, fixtures, and other 
property which it has placed or affixed within or to the Licensed Space, 
provided Licensee repairs damage caused by such removal.  Licensee shall not 
remove improvements made to the facilities or Licensed Space by UFRFI or on 
behalf of UFRFI during this Agreement.

19.  Use of Names.  Licensee shall not use the names of BDI, the 
University, or UFRFI nor of any of such institution's employees, nor any 
adaptation thereof, in any advertising, promotional, or sales literature 
without prior written consent obtained from UFRFI in each case, except that 
Licensee may state that it is a licensee of UFRFI pursuant to this Agreement, 
that it is a participant in the Incubator Program, and, where relevant, that 
UFRFI is the owner of warrants for, or shares of, its common stock.       
Licensee will cooperate fully with UFRFI to publicize the Incubator Program 
and Licensee's participation in such program.
 
(a) Request for Consent to Use of Names.  Requests for consent 
from UFRFI shall be sent to the Incubator Manager.   Notwithstanding the 
foregoing, the University and UFRFI consent to references to them pursuant to 
any requirements of applicable law or governmental regulations, provided that, 
in the event of any such disclosure, Licensee shall afford UFRFI the prior 
opportunity to review the text of such disclosure.  Licensee shall use its 
best efforts to comply with any reasonable requests by UFRFI regarding 
changes.

(b) Consent Deemed Granted.  Where consent of a party is required 
under this Section, such consent shall be deemed granted if no written 
objection (or oral objection, confirmed immediately in writing) is received by 
the requesting party on or before the twentieth calendar day following the 
date a written request for consent was received by the requested party.  For 
the purposes of this Section only, a item shall be deemed received as follows: 
(i) if hand delivered, upon delivery; (ii) if sent by electronic mail, upon 
confirmation by the sending carrier that the message was deposited to the 
addressee's mailbox; (iii) if sent by registered mail, return receipt 
requested, upon signing by the receiving party; or (iv) if sent by ordinary 
mail in the United States, postage prepaid, and addressed as set forth below, 
on the fifth calendar day after deposit in the mail. 

20.  No Partnership.  Nothing contained in this Agreement shall create 
any partnership or joint venture between the parties.  Neither party may 
pledge the credit of the other or make any binding commitment on the part of 
the other.

21.  Miscellaneous.  The parties hereto acknowledge that this Agreement 
sets forth the entire agreement and understanding of the parties hereto as to 
the subject matter hereof, and shall not be subject to any change or 
modification except by the execution of a written instrument subscribed to by 
the parties hereto.  The provisions of this Agreement are severable, and in 
the event that any provisions of this Agreement shall be determined to be 
invalid or unenforceable under any controlling body of the law, such 
invalidity or unenforceability shall not in any way affect the validity or 
enforceability of the remaining provisions hereof.  The titles herein are for 
convenience only.  This Agreement shall be construed, governed, interpreted, 
and applied in accordance with the laws of the State of Florida.

22.  Notices.  Any payment, notice or other communication pursuant to 
this Agreement shall be sufficiently made or given on the date of mailing if 
sent to such party by certified first class mail, postage prepaid, addressed 
to it at its address below or as it shall designate by written notice given to

the term for which the Patent Rights are granted or the expiration date of the 
last to expire patent hereunder, whichever is later, unless sooner terminated 
according to the terms hereof.  

     2.2     Licensors shall not grant any other license to make, have made, 
use, lease, or sell Licensed Products or to utilize Licensed Processes during 
the period of time commencing with the Effective Date of this Agreement and 
terminating with the expiration or termination of this Agreement.

     2.3     Licensors reserve the right to practice under the Patent Rights 
for their own noncommercial research purposes.

     2.4     Ixion may sublicense others under this Agreement.  Each 
sublicense 
shall be consistent with the terms of this Agreement. 

     2.5     Any sublicenses granted by Ixion shall provide that the 
obligations to Licensors of this Agreement shall be binding upon the 
sublicensee as if it were a party to this Agreement.  Ixion shall attach 
copies of this Agreement to sublicense agreements. 

     2.6     Ixion shall forward to Licensors a copy of any sublicense 
agreement within 30 days of its execution and further shall forward to 
Licensors annually a copy of such reports received by Ixion from its 
sublicensees during the preceding twelve-month period under the sublicenses as 
shall be pertinent to a royalty accounting under said sublicenses.

     2.7     The license granted hereunder shall not be construed to confer 
any 
rights upon Ixion by implication, estoppel, or otherwise as to any technology 
not specifically set forth herein.


ARTICLE III - COMMERCIAL DUE DILIGENCE

     3.1     Ixion shall use commercially reasonable efforts to bring one or 
more Licensed Products or Licensed Processes to market through a program 
intended to attain  commercialization of Licensed Products and Licensed 
Processes.

             ARTICLE IV - ROYALTIES

     4.1     For the rights, privileges and, license granted hereunder, Ixion 
shall pay royalties to Licensors to the end of the term of the Patent Rights 
or the expiration date of the last to expire patent hereunder, whichever is 
later, unless sooner terminated according to the terms hereof, as follows:

          (a)     A License Issue Fee of 1,000 shares of Common 
Stock of Ixion;

          (b)     A Running Royalty in an amount equal to 2.0% of 
the Net Sales of the Licensed Products or Licensed Processes 
used, leased, or sold by or for Ixion or its sublicensees.

     4.2     No multiple royalties shall be payable because any Licensed 
Product, its manufacture, use, lease, or sale are or shall be covered by more 
than one Patent Rights patent application or Patent Rights patent licensed 
under this Agreement.

     4.3     Royalty payments shall be paid in United States dollars in 
Gainesville, Florida or at such other place as Licensors may reasonably 
designate in writing consistent with the laws and regulations controlling in 
any foreign country.  If any currency conversion shall be required in 
connection with the payment of royalties hereunder, such conversion shall be 
made by using the exchange rate prevailing at the Chase Manhattan Bank (N.A.) 
on the last business day of the calendar quarterly reporting period to which 
such royalty payments relate.

     4.4     In the event the royalties set forth herein are higher than the 
maximum royalties permitted by the law or regulations of a particular country, 
the royalty payable for sales in such country shall be equal to the maximum 
permitted royalty under such law or regulations.  Notice of said event shall 
be provided to Licensors.  Ixion shall notify Licensors, in writing, within 90 
days of discovering that such royalties are approaching or have reached the 
maximum amount, and shall provide Licensors with written documentation 
regarding the laws or regulations establishing such maximum.

     4.5     In the event that any taxes, withholding or otherwise, are levied 
by any taxing authority in connection with accrual or payment of any royalties 
payable by Ixion under this Agreement, and Ixion determines in good faith that 
it must pay such taxes, Ixion shall have the right to pay such taxes to the 
local tax authorities on behalf of Licensors and payment of the net amount due 
after reduction by the amount of such taxes, shall fully satisfy Ixion's 
royalty obligations under this Agreement.  Ixion shall provide Licensors with 
appropriate receipts or other documentation supporting such payment.  Ixion 
shall inform Licensors in writing, within 90 days of notification that taxes 
will or have been levied by a taxing authority.

     4.6     In the event that a Licensed Product is sold in a combination 
package or kit containing other active products, then Net Sales for purposes 
of determining royalty payments on the combination package, shall be 
calculated using one of the following methods, but in no event shall the 
royalties payable to Licensors be reduced to less than 25% of that provided 
for in Section 4.1 above:

     (a)     by multiplying the net selling price of that combination 
package by the fraction A/A+B, where A is the gross selling price, 
during the royalty-paying period in question, of the Licensed 
Product sold separately, and B is the gross selling price during 
the royalty period in question, of the other active products sold 
separately; or
     (b)     in the event that no such separate sales are made of the 
Licensed Product or any of the active products in such combination 
package during the royalty-paying period in question, Net Sales 
for the purposes of determining royalty payments, shall be 
calculated by dividing the net selling price of the combination 
package by the number of functions performed by the combination 
package sold where such package contains active agents other than 
those licensed under this Agreement.  The parties recognize that 
this provision will require consultation and that in the event a 
combination package or kit circumstance arises, the parties will 
negotiate in good faith to determine the calculation of Net Sales 
pursuant to this section.

     4.7     If it is necessary for Ixion to take any license(s) in any given 
country, under third-party patents in order to practice the Licensed Processes 
or produce the Licensed Products in that country, then Ixion can deduct up to 
50% of the royalties otherwise due under this Agreement for Net Sales in that 
country, until such time as Ixion has recovered an amount equal to the 
royalties payable to such third parties.

    ARTICLE V - REPORTS AND RECORDS

     5.1     Ixion shall keep accurate books of account for the purpose of 
showing the amounts payable to Licensors hereunder.  Said books of account 
shall be kept at Ixion's principal place of business or the principal place of
business of the appropriate division of Ixion to which this Agreement relates.
Said books and the supporting data shall be open at all reasonable times for 
one year following the end of the calendar year to which they pertain, to the 
inspection of Licensors or its agents at Licensor's expense for the purpose of 
verifying Ixion's royalty statements.

     5.2     Ixion, within 45 days after December 31 of each year, shall 
deliver to Licensors accurate reports, giving such particulars of the business 
conducted by Ixion and its sublicensees during the preceding twelve-month 
period under this Agreement as shall be pertinent to a royalty accounting 
hereunder.  These shall include at least the following:

          (a)     number of Licensed Products manufactured and 
sold;

          (b)     total billings for Licensed Products sold;

          (c)     an accounting for all Licensed Processes used or 
sold;

          (d)     deductions applicable to a determination of Net 
Sales;

          (e)     total royalties due; and

          (f)     names and addresses of all sublicensees of 
Ixion.

     5.3     With each such report submitted, Ixion shall pay to Licensors the 
royalties due and payable under this Agreement.  If no royalties shall be due, 
Ixion shall so report.

     5.4  On or before the 90th day following the close of Ixion's fiscal 
year, Ixion shall provide Licensors with Ixion's year-end balance sheet and an 
operating statement for the preceding fiscal year then ended.

     5.5     The royalty payments, license fees, and reimbursement for patent-
related expenses set forth in this Agreement shall, if overdue, bear interest 
until payment at the monthly rate of 1.0%.  The payment of such interest shall 
not foreclose Licensors from exercising any other rights it may have as a 
consequence of the lateness of any payment.

    ARTICLE VI - PATENT PROSECUTION

     6.1     Ixion shall apply for, seek issuance of, and maintain during the 
term of this Agreement the Patent Rights in the United States and in the 
foreign countries listed in Appendix B hereto to the extent, in its sole 
discretion, it deems such actions commercially reasonable. Licensors shall 
have reasonable opportunities to advise Ixion and shall cooperate with Ixion 
in such prosecution, filing, and maintenance. 

     6.2     Payment of all fees and costs relating to the filing, 
prosecution, 
and maintenance of the Patent Rights shall be the responsibility of Ixion 
after the Effective Date. 
     
         ARTICLE VII - INFRINGEMENT

     7.1     Licensors shall inform Ixion promptly in writing of any alleged 
infringement of the Patent Rights by a third party and of any available 
evidence thereof.

     7.2     During the term of this Agreement, Ixion shall have the right, 
but 
shall not be obligated, to prosecute at its own expense any such infringements 
of the Patent Rights.  If Ixion prosecutes any such infringement, Licensors 
agrees that Ixion may include Licensors as a co-plaintiff in any such suit, 
without expense to Licensors.  The total cost of any such infringement action 
commenced or defended solely by Ixion shall be borne by Ixion and Ixion shall 
keep any recovery or damages for past infringement derived therefrom.

     7.3     If within six months after having been notified of any alleged 
infringement or such shorter time proscribed by law, Ixion shall have been 
unsuccessful in persuading the alleged infringer to desist or shall not have 
brought and shall not be diligently prosecuting an infringement action, or if 
Ixion shall notify Licensors at any time prior thereto of its intention not to 
bring suit against any alleged infringer, then, and in those events only, 

     (a)     Licensors shall have the right, but shall not be obligated, 
to prosecute at its own expense any infringement of the Patent 
Rights (keeping any recovery or damages for past infringements 
derived therefrom), and Licensors may, for such purposes, use the 
name of Ixion as co-plaintiff.  No settlement, consent judgment, 
or other voluntary final disposition of the suit may be entered 
into without the consent of Ixion, which consent shall not 
unreasonably be withheld.  Licensors shall indemnify Ixion against 
any order for costs that may be made against Ixion in such 
proceedings.

     (b)     Payments which are earned under Article IV hereof shall be 
waived so long as any such infringement which the parties agree in 
good faith is material continues, such waiver not to exceed 75% of 
the royalties payable hereunder.

     7.4     If Licensors has brought a suit pursuant to section 7.3 above, it 
shall have the right for such purpose to join Ixion as a co-plaintiff at 
Ixion's expense. Ixion independently shall have the right to join any such 
suit or action brought by Licensors, and, in such event, shall pay one-half of 
the cost of such suit or action from the date of joining.  Any damages 
recovered by a suit or action in which Ixion has paid its share of costs shall 
be first used to reimburse each party hereto for the cost of such suit or 
action (including attorney's fees) actually paid by each party hereto as the 
case may be, then to reimburse Licensors for any payments waived under this 
Section 7.4, and the residue, if any, shall be divided equally between the 
parties hereto.

     7.5     In the event that a declaratory judgment action alleging 
invalidity or noninfringement of any of the Patent Rights shall be brought 
against Ixion, Licensors, at its option, shall have the right, within 30 days 
after commencement of such action, to intervene and take over the sole defense 
of the action at its own expense.

     7.6     In any infringement suit as either party may institute to enforce 
the Patent Rights pursuant to this Agreement, the other party hereto shall, at 
the request and expense of the party initiating such suit, cooperate in all 
respects and, to the extent possible, have its employees testify when 
requested and make available relevant records, papers, information, samples, 
specimens, and the like.

   ARTICLE VIII - PRODUCT LIABILITY

     8.1     Ixion shall at all times during the term of this Agreement and 
thereafter, indemnify, defend, and hold Licensors harmless against all claims 
and expenses, including legal expenses and reasonable attorneys' fees, whether 
arising from a third party claim or resulting from Licensor's enforcing this 
indemnification clause against Ixion, or arising out of the death of or injury 
to any person or persons or out of any damage to property and against any 
other claim, proceeding, demand, expense, or liability of any kind whatsoever 
resulting from the production, manufacture, sale, use, lease, consumption, or 
advertisement of the Licensed Products and/or Licensed Processes or arising 
from any right or obligation of Ixion hereunder.  This indemnification shall 
not apply to any liability, damage, loss, or expense to the extent that it is 
attributable to the negligence or intentional wrongdoing of the Licensors.

     8.2     At such time as any product, process, or service relating to, or 
developed pursuant to, this Agreement is being commercially distributed or 
sold (other than for the purpose of obtaining regulatory approvals) by Ixion 
or by a licensee, affiliate, or agent of Ixion, Ixion shall, at its sole cost 
and expense, procure and maintain policies of comprehensive general liability 
insurance naming Licensors as additional insureds.  Such comprehensive general 
liability insurance shall provide (a) product liability coverage, and (b) 
broad form contractual liability coverage for Ixion's indemnification under 
sections 8.1 and 8.2 above.  Ixion may elect to self-insure.

     8.3     Ixion shall provide Licensors with written evidence of such 
insurance upon request, and shall provide Licensors with written notice at 
least 45 days prior to the cancellation, non-renewal, or material change in 
such comprehensive general liability insurance; if Ixion does not obtain 
replacement insurance providing comparable coverage within such 45 day period, 
Licensors shall have the right to terminate this Agreement.

     8.4     Ixion shall maintain such comprehensive general liability 
insurance beyond the expiration or termination of this Agreement during (a) 
the period that any product, process, or service, relating to, or developed 
pursuant to, this Agreement is being commercially distributed or sold (other 
than for the purpose of obtaining regulatory approvals) by Ixion or by a 
licensee, affiliate, or agent of Ixion, and (b) a reasonable period after the 
period referred to in section 8.5 (a) above, which in no event shall be less 
than 15 years.

     8.5     In the event any such action is commenced or claim made or 
threatened against Licensors or other Indemnitees as to which Ixion is 
obligated to indemnify it or them or hold it or them harmless, Licensors or 
the other Indemnitees shall promptly notify Ixion of such event.  Ixion shall 
assume the defense of, and may settle, that part of any such claim or action 
or made against Licensors (or other Indemnitee) which relates to Ixion's 
indemnification and Ixion may take such other steps as may be necessary to 
protect itself.  Ixion shall not be liable to Licensors or other Indemnitees 
on account of any settlement of any such claim or litigation affected without 
Ixion's consent.  The right of Ixion to assume the defense of any action shall 
be limited to that part of the action commenced against Licensors or other 
Indemnitees which relates to Ixion's obligation of indemnification.

          ARTICLE IX - DISCLAIMER OF WARRANTIES

9.1     EXCEPT AS OTHERWISE EXPRESSLY SET FORTH IN THIS AGREEMENT, Licensors 
MAKES NO REPRESENTATIONS AND EXTENDS NO WARRANTIES OF ANY KIND, EITHER EXPRESS 
OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, 
FITNESS FOR A PARTICULAR PURPOSE, AND VALIDITY OF PATENT RIGHTS CLAIMS, ISSUED 
OR PENDING.

9.2     Licensors DOES NOT WARRANT THE VALIDITY OF THE PATENT RIGHTS LICENSED 
HEREUNDER AND MAKES NO REPRESENTATION WHATSOEVER WITH REGARD TO THE SCOPE OF 
THE LICENSED PATENT RIGHTS OR THAT SUCH PATENT RIGHTS MAY BE EXPLOITED BY 
IXION OR ANY AFFILIATE OR SUBLICENSEE WITHOUT INFRINGING OTHER PATENTS.

          ARTICLE X - ASSIGNMENT

     10.1     This Agreement is not assignable.

           ARTICLE XI - TERMINATION

     11.1     If Ixion shall cease to carry on its business, this Agreement 
shall terminate upon notice by Licensors.

     11.2     Should Ixion fail to pay Licensors royalties due and payable 
hereunder, Licensors shall have the right to terminate this Agreement on 90 
days' notice, unless Ixion shall pay Licensors within the 90-day period, all 
such royalties and interest due and payable.  Upon the expiration of the 90-
day period, if Ixion shall not have paid all such royalties and interest due 
and payable, the rights, privileges, and license granted hereunder shall 
terminate.

     11.3     Upon any material breach or default of this Agreement by Ixion, 
other than those occurrences set out in sections 11.1 and 11.2 above, which 
shall always take precedence in that order over any material breach or default 
referred to in this section 11.3, Licensors shall have the right to terminate 
this Agreement and the rights, privileges, and license granted hereunder by 90 
days' notice to Ixion.  Such termination shall become effective unless Ixion 
shall have cured any such breach or default prior to the expiration of the 90-
day period.

     11.4     Ixion shall have the right to terminate this Agreement at any 
time 
on 90 days' written notice to Licensors, and upon payment of all amounts due 
Licensors through the effective date of the termination.

     11.5     Upon termination of this Agreement for any reason, nothing 
herein 
shall be construed to release either party from any obligation that matured 
prior to the effective date of such termination.  Ixion and any sublicensee 
thereof may, however, after the effective date of such termination, sell all 
Licensed Products, and complete Licensed Products in the process of 
manufacture at the time of such termination and sell the same, provided that 
Ixion shall pay to Licensors the royalties thereon as required by Article IV 
of this Agreement and shall submit the reports required by Article V hereof on 
the sales of Licensed Products.

     11.6     Upon termination of this Agreement for any reason, any 
sublicense 
not then in default shall continue in full force and effect except that 
Licensors shall be substituted in place of the sublicensor; provided, however, 
that the extent of Licensor's obligations under such sublicense shall be 
consistent with (and not exceeding) its obligations under this Agreement.

     11.7     Bankruptcy.

          (a)     Notice of Assumption or Rejection.

               (i)     In the event that either party files 
or has filed against it a petition under the Federal 
Bankruptcy Code (11 U.S.C. SS 1, et seq.) (the 
"Bankruptcy Code"), is adjudged bankrupt, or files or 
has filed against it a petition for reorganization or 
arrangement under any law relating to bankruptcy or 
similar laws for the protection of debtors, whether 
under the laws of the United States and its political 
subdivisions or otherwise, such party shall (1) notify 
the  other party thereof within ten days after the 
filing of such petition or such adjudication, and (2), 
within 30 days after the filing of such petition, 
shall notify the other party of the party's assumption 
or rejection of this Agreement, and shall file a 
petition with the appropriate court for approval of 
all other action as may be necessary to obtain the 
approval of such petition and of such assumption or 
rejection.

               (ii)     If such party does not:  (1) within 
thirty (30) days after the occurrence of any of the 
foregoing events, notify the other party of its 
assumption or rejection of this Agreement or file the 
petition, or (2) thereafter diligently take all other 
action necessary for the approval of the foregoing 
petition or of such assumption or rejection, such 
party shall be deemed to have rejected this Agreement.  
Each party acknowledges that, for purposes of Section 
365 of the Bankruptcy Code and similar provisions of 
any other or future similar laws relating to any 
party's assumption or rejection of any executory 
contract, a period of 30 days after the date of any 
filing or adjudication described above shall 
constitute a reasonable time in which such party shall 
assume or reject this Agreement and a party shall be 
deemed to have not diligently taken all action 
necessary for the approval of the foregoing petition 
or of such assumption or rejection if such petition, 
assumption or rejection is not approved by the 
appropriate court within 60 days after the filing of 
the petition for such assumption or rejection.

          (b)     Conditions to Assumption.  

               No election by any party, or any successor-in-
interest to such party, to assume this Agreement as 
contemplated by Section (a) above shall be effective unless 
each of the following conditions, each of which each party 
acknowledges is commercially reasonable in the context of a 
bankruptcy or similar proceeding, has been satisfied by such 
party and each of the other parties has acknowledged such 
satisfaction in writing:

               (1)     Cure.  Such party has cured, or has 
provided the other party adequate assurances that:

                    (A)     Monetary Defaults.  
Within ten days from the date of such assumption 
such party will cure all monetary defaults under 
this Agreement; and

                    (B)     Non-Monetary Defaults.  
Within 30 days from the date of such assumption 
such party will cure all non-monetary defaults 
under this Agreement.

               (2)     Pecuniary Loss.  Such party has 
compensated or has provided to the other party 
adequate assurances that within ten days from the date 
of assumption the other party will be compensated for 
any pecuniary loss incurred by the party arising from 
any default of such party under this Agreement prior 
to the assumption.

               (3)     Future Performance.  Such party has 
provided the other party with adequate assurances of 
the future performance of such party's obligations 
under this Agreement.

          (c)     Termination.   This Agreement shall terminate 
upon the rejection of this Agreement as contemplated by this 
Section by any party or successor-in-interest thereto.

          (d)     No Transfer.  Neither any party's interest in 
this Agreement nor any portion thereof shall pass to any 
trustee, receiver, or assignee for the benefit of creditors, 
or any other person or entity or otherwise by operation of 
law under the Bankruptcy Code or the insolvency laws of any 
state having jurisdiction of the person or property of such 
party unless the other party shall consent to such transfer 
in writing.

determined by the law of the country in which the patent was granted.

     13.2     This Agreement sets forth the entire agreement and understanding 
of the parties hereto as to the subject matter hereof, and shall not be 
subject to any change or modification except by the execution of a written 
instrument subscribed to by the parties hereto.

     13.3     The provisions of this Agreement are severable, and in the event 
that any provisions of this Agreement shall be determined to be invalid or 
unenforceable under any controlling body of the law, such invalidity or 
unenforceability shall not in any way affect the validity or enforceability of 
the remaining provisions hereof.

     13.4     Ixion agrees to mark the Licensed Products sold in the United 
States with all applicable United States patent numbers.  All Licensed 
Products shipped to or sold in other countries shall be marked in such a

manufacture or sale.

     13.5     The failure of either party to assert a right hereunder or to 
insist upon compliance with any term or condition of this Agreement shall not 
constitute a waiver of that right or excuse a similar subsequent failure to 
perform any such term or condition by the other party.

     13.6     (a) Anything in this Agreement to the contrary notwithstanding, 
any and all knowledge, know-how, practices, process or other information of 
any kind and in any form (hereinafter referred to as "Confidential

confidentiality agreements) to its lawyers, accountants, advisors, investors, 
and potential investors.  Furthermore, neither party shall use the said 
Confidential Information for any purpose other than those purposes specified 
in this Agreement.  The parties may disclose Confidential Information to the 
minimum number of its employees reasonably requiring access thereto for the 
purposes of this Agreement provided, however, that prior to making any such 
disclosures each such employee shall be apprised of the duty and obligation to 
maintain Confidential Information in confidence and not to use such 
information for any purpose other than in accordance with the terms and 
conditions of this Agreement.

          (b)   Nothing contained herein will in any way restrict or impair 
either parties right to use, disclose, or otherwise deal with any Confidential 
Information which at the time of its receipt:

          (i)  Is generally available in the public domain, or thereafter 
becomes available to the public through no act of the receiving party; or

          (ii)  Was independently known prior to receipt thereof, or made 
available to such receiving party as a matter of lawful right by a third 
party.

     13.7     Licensors will use his best efforts to assist Ixion in the 
transfer of the technology represented by the Patent Rights through 
consultation, making available experimental data, or otherwise.  

     
     IN WITNESS WHEREOF, the parties have hereunto set their hands and seals 
and duly executed this Agreement as of the day set forth first above.

The Executive is currently employed as Chairman of the Board of 
Directors and Chief Executive Officer of the Company.  The Company wishes to 
assure itself and the Executive of continuity of management both before or

Exchange Act of 1934, as amended); or


(iii) during any period of 24 consecutive months commencing on the 
Agreement Date, individuals who at the beginning of such period were

agrees to work diligently throughout the Period of Employment to achieve any 
such performance objectives that shall then exist.

Executive's principal business office shall be located in or near Gainesville,

4.     RESTRICTIVE COVENANTS

(A)     Noncompetition.  The Executive agrees that during the Period of 
Employment and for the six-month period immediately following the Period of 
Employment, the Executive shall not, directly or indirectly, in any capacity, 
engage in any business which is substantially competitive with any business 
then actively conducted by the Company or any of its affiliates or 
subsidiaries, and the Executive shall not undertake to consult with or advise 
any such competitive business or otherwise, directly or indirectly, engage in 
any activity which is substantially competitive with or in any way adversely 
and substantially affects any activity of the Company or any of its affiliates 
or subsidiaries.
(B)     Nondisclosure.  Except as expressly provided herein, the 
Executive agrees that during the Period of Employment and thereafter, the 
Executive shall not make use of, disclose, divulge, or make accessible, to any 
third party, any information of a secret or confidential nature known to the 
Executive in the course of his employment with the Company or any of its 
affiliates or subsidiaries until such information has come into the public 
domain or has otherwise ceased to be secret or confidential.
(C)     Inventions.   All patentable and unpatentable inventions, 
discoveries, and ideas, which are made or conceived by the Executive during 
the term of this Agreement  shall be the Company's sole and exclusive property 
throughout the world.  Promptly upon conception of such invention, discovery, 
or idea, the Executive will disclose it to the Company which shall have full 
power and authority to file and prosecute patent applications throughout the 
world thereon and to procure and maintain patents thereon.  The Executive 
shall, at the Company's request and expense, execute documents and perform 
such acts as counsel may deem advisable, to confirm in the Company all right, 
title, and interest throughout the world, in and to, such invention, 
discovery, or idea, and all patent applications, patents, and copyrights 
thereon, and to enable and assist the Company in procuring, maintaining, 
enforcing and defending patents, petty patents, copyrights, and other

discovery, or idea which may be patentable or copyrightable.
(D)     Specific Performance and Injunctive Relief.  The Executive 
acknowledges and agrees that the Company or its affiliates and subsidiaries 
will suffer irreparable injury if the provisions of this Section 4 are not 
honored, that damages resulting from such injury will be incapable of being 
precisely measured, and that the Company and its subsidiaries and affiliates 
will not have an adequate remedy at law to redress the harm which such 
violation shall cause.  Accordingly, the Executive agrees that the Company 
shall have the rights and remedies of specific performance and injunctive 
relief, in addition to any other rights or remedies that may be available at 
law or in equity, in respect of any failure, or threatened failure, on the 
part of the Executive to comply with the provisions of this Section 4, 
including, but not limited to, temporary restraining orders and temporary 
injunctions to restrain any violation or threatened violation of this 
Agreement by the Executive.

5.     COMPENSATION, PERQUISITES, AND EMPLOYEE BENEFITS

(A)     Base Compensation.  For all substantially full time services 
rendered during the Period of Employment, the Executive shall receive annual 
base compensation at an initial rate of $75,000, which shall be increased, at 
least annually, in accordance with the Company's regular administrative 
practices generally applicable to its senior executives.  At the Agreement 
Date, such rate is acknowledged to be below the median base compensation as 
reported by industry surveys relating to private companies of equivalent size. 
 Upon a determination by the Board of Directors that the Company has obtained 
adequate initial financing, the Executive's base compensation shall be 
increased to not less than the median base compensation as reported by the 
most recent edition of Leadership in Biotechnology or any substantially 
equivalent compensation survey chosen by the Board of Directors, and 
thereafter, during the Period of Employment, shall not fall below such median 
as reported from time to time in such survey.  The Executive's cash base 
compensation shall never be less than the base compensation paid to any other 
senior management executive of the Company.
(B)     Incentive Compensation.  During the Period of Employment, the 
Executive shall be and continue to be a full participant in the Company's 
Annual Bonus Plan and Stock Option Plans (the "Incentive Plans"), as the 
Incentive Plans are in effect from time to time with such improvements in the 
Incentive Plans or other incentive compensation plans as may from time to time 
be made in accordance with the practices of the Company.  The Executive shall 
be entitled to participate in any other incentive compensation plans generally 
available to senior executives of the Company.  If any of the Incentive Plans 
are terminated or discontinued, the Executive shall be entitled to participate 
in other incentive compensation plans with terms at least as favorable to the 
Executive as the Incentive Plans in effect prior to the termination or 
discontinuance of the Incentive Plans.
(C)     Perquisites.  During the Period of Employment, the Executive 
shall be entitled to one club membership to be used for business purposes, and 
shall be entitled to such other perquisites and fringe benefits, as shall be 
approved by the Board of Directors.  Upon a determination by the Board of 
Directors that the Company has obtained adequate initial financing, the 
Executive's perquisites shall include such perquisites generally available to 
officers of his rank at companies of equivalent size and status in the 
biotechnology industry, including without limitation a leased automobile, 
first class air travel, additional club memberships, supplemental retirement 
income, financial and legal counseling, and other perquisites.
(D)     Employee Benefits.  During the Period of Employment, the 
Executive shall be entitled to participate in all employee benefit plans and 
programs as in effect for senior executives of the Company ("Plans") under the 
terms of the Plans, with such improvements in the Plans as may from time to 
time be made in accordance with the practices of the Company.  The Executive 
shall be entitled to participate in any employee benefit plans and programs 
generally available to senior executives of the Company.  If any of the Plans 
are terminated or discontinued, the Executive shall be entitled to participate 
in other employee benefit plans with terms at least as favorable to the 
Executive as the Plans as in effect prior to the termination or discontinuance 
of the Plans.
(E)     Other Obligations of the Company.  Any increases in base and 
incentive compensation, perquisites or employee benefits under this Agreement 
or otherwise shall not diminish any other obligation of the Company hereunder.

6.     DEATH OR DISABILITY

(A)     Death.  If the Executive should die during the Period of 
Employment, his employment shall be deemed to have ceased on the last day of 
the month in which death shall have occurred.
(B)     Disability.  "Disability" shall mean an illness or accident 
which the Board of Directors determines in its discretion will or has 
prevented the Executive from performing his duties under this Agreement for a 
period of six consecutive months.  In the event that the Executive incurs a 
Disability during the Period of Employment, his employment shall be deemed to 
have ceased on the last day of such six-month period.

7.     TERMINATION

(A)     Cause.  Upon a determination by the Board of Directors, the 
Company shall have the right at any time to terminate the Executive's 
employment with the Company.  The termination of the Executive's employment by 
the Company during the Contract Term shall be deemed to be for "cause" only if 
such termination shall be the result of any of the following:

(i) an act or acts of dishonesty by the Executive resulting 
in conviction for a felony or conviction of a misdemeanor 
involving moral turpitude;

(ii) a deliberate and intentional failure by the Executive 
during the Period of Employment (except by reason of 
incapacity due to illness or accident) to comply with the 
provisions of this Agreement relating to the time and best 
efforts to be devoted by the Executive to the affairs of the 
Company; 

(iii) the Executive's gross misconduct, if such conduct 
results in demonstrably material injury to the Company; or

(iv)  following a unanimous vote of the Board of Directors (the 
Executive abstaining), the Board determines that the Executive 
materially failed to meet the reasonable performance objectives 
established by the Board for Company-wide performance and for 
performance by the Executive;

provided that notice of such termination is given in accordance with Section 
7(C) below.
(B)     Good Reason.  The Executive shall have the right at any time to 
terminate his employment with the Company.  Termination by the Executive shall 
be deemed to be for "Good Reason" only if such termination shall be the result 
of the following:
(i) a reduction during the Period of Employment in the 
current level of the Executive's aggregate compensation, 
including his annual base compensation, Annual Bonus Plan 
awards, Stock Option Plan awards, employee benefit plan 
coverages, and perquisites (other than a reduction in awards 
or benefits that is generally applicable to participants in 
a plan in accordance with the terms of the plan); 

(ii) a diminishment during the Period of Employment in the 
Executive's position, powers, authority, duties, or 
responsibilities, or the business to which those powers, 
authority, duties, or responsibilities apply; removal during 
the Period of Employment of the Executive from the highest 
office held on or after the Agreement Date; or change during 
the Period of Employment in the Executive's chain of 
supervision as it existed as of the Agreement Date (unless 
as a result of, and only during, Executive's Disability); or 
 

(iii) a material beach of this Agreement by the Company;

provided that notice of the Executive's election to terminate his employment 
under this Agreement is given in accordance with Section 7(C) below.  Failure 
to elect to terminate with respect to one event giving rise to Good Reason 
does not preclude the Executive from making the election with respect to a 
subsequent event.
(C)     Termination Procedure.
(1)     Notice.     
(a)  Notice of termination of employment under this Agreement 
shall be provided in writing by the Company or the Executive, as applicable, 
and shall specify the date as of which the Executive's employment shall be 
deemed to have ceased, which date shall in no event be earlier than 60 days 
from the date of such notice.
(b)  In the event that the Company elects to terminate employment, 
the Company shall provide to the Executive the notice described in Section

7(A), with the particulars thereof specified in detail.
(c)  In the event that the Executive elects to terminate 
employment, the Executive shall provide to the Company the notice described in

in Section 7(B), with the particulars thereof specified in detail, and shall 
be given, except in the case of a continuing breach, within three calendar 
months after the most recent event giving rise to Good Reason.
(2)     Cure.          
(a)  In the case of the Executive's alleged breach or gross 
misconduct set forth in Sections 7(A)(ii) or (iii), the Executive shall be 
given the opportunity to remedy such alleged breach or gross misconduct within 
30 days from his receipt of the notice referred to above, or take all 
reasonable steps to that end during such 30-day period and thereafter.
(b)  In the case of the Executive's allegation of Good Reason, the 
Company shall be given the opportunity to remedy the alleged Good Reason 
within 30 days from its receipt of the notice referred to above, or take all 
reasonable steps to that end during such 30-day period and thereafter.
(3)     Arbitration.  In the event that the Executive's employment 
shall be terminated by the Company and such termination is alleged to be for 
Cause, the Executive shall have the right, in addition to all other rights and 
remedies provided by law or equity, to seek arbitration as described below.  
In the event that the Executive's employment shall be terminated by the 
Executive and such termination is alleged to be for Good Reason, the Company 
shall have the right, in addition to all other rights and remedies provided by 
law or equity, to seek arbitration as described below.  Such arbitration shall 
be sought in Alachua County, State of Florida, under the rules of the American 
Arbitration Association, by serving notice to arbitrate upon the other party 
no more than 60 days after such party received the notice of termination 
referred to above.

8.     CONSEQUENCES OF TERMINATION, DEATH OR DISABILITY

(A)     Termination by the Company Other Than for Cause or by the 
Executive for Good Reason.  In the event of a termination by the Company of 
the Executive's employment during the Contract Term other than for Cause or by 
the Executive for Good Reason, the Company shall, as liquidated damages, pay 
to the Executive and provide him, in lieu of all other rights, remedies, 
damages, and relief to which he might otherwise be entitled under this 
Agreement, with the benefits described below in this Section 8(A):

lesser of such amount and 299% of the "base amount" of the Executive as

compensation for such year multiplied by item (ii) of Section 8(A)(2)(b) 
below; and
  (b)  an amount in respect of the annual incentive compensation 
that would have been earned in respect of the year in which such Termination 
Date occurs, in an amount calculated by multiplying (i) the rate of annual 
base compensation in effect for the Executive immediately prior to the 
Termination Date by (ii) the average of the annual awards under the Annual 
Bonus Plan payable in respect of the two calendar years immediately preceding 
the year for which payment is made, with each such award expressed as a 
percentage of the annual base compensation paid to the Executive for the 
respective calendar years.

States.

of any loan to the Company, or any deferred compensation account into voting 
common stock of the Company at a price equal to the lowest price (after 
adjustment for stock splits or stock dividends) at which common stock has been 
sold (other than pursuant to the exercise of outstanding options under the 
Stock Option Plan, the Board Retainer Plan, or any similar plan) at any time 
during the 24 months immediately preceding the Termination Date.  Such right 
shall be exercisable not later than 60 days after the Termination Date.

Executive shall receive the amounts and arrangements, if any, ordinarily 
provided to senior executives of the Company upon termination of employment in 
accordance with the plans, programs, and practices of the Company applicable 
to senior executives, as in effect on the Termination Date or, at Executive's 
election, on the date of a Change in Control.  In addition, the Executive

subordinated note agreement, and any other agreement between the Company and 
the Executive executed on or after the Agreement Date.

any other payments due in respect of the Executive's death or Disability.
(2)     Death.  In the event of the death of the Executive during the 
Period of Employment, the Executive's representative shall be entitled to the

this Section 8(B): an award under the Annual Bonus Plan, determined in 
accordance with Section 8(A)(2) on a pro-rata basis, for the portion of the 
calendar year prior to the Termination Date (or, in the case of Disability, 
the earlier of the Termination Date and the Expiration Date).
(4)     Reduction of Payments.  The amount of any payments due under 
this Section 8(B) shall be reduced by any payments to which the Executive is 
entitled for the same period because of disability under any disability 
benefit plan of the Company providing salary continuation.
(C)     Termination by the Company for Cause or by the Executive Other 
Than for Good Reason.     In the event of a termination by the Company of the

9.     INTEREST ASSUMPTIONS

upon a discount rate equal to 120 percent of the applicable Federal rate 
(determined under section 1274(d) of the Internal Revenue Code of 1986 and the 
regulations thereunder), compounded semiannually.  The Executive shall be 
deemed to have elected the discount rate as in effect on the Agreement Date.  
The Company hereby agrees to use the discount rate that is deemed to be

11.     INDEMNIFICATION AND INSURANCE; LEGAL EXPENSES

(A)     Indemnification and Insurance.  The Company will indemnify the

the proceeding) to the fullest extent permitted by the laws of the State of 
Florida and the Certificate of Incorporation and By-Laws of the Company, in 
each case as in effect on the date of the Change in Control or on the 
Termination Date, whichever affords greater protection to the Executive; and 
the Executive shall be entitled to the protection of any insurance policies 
the Company may elect to maintain generally for the benefit of its directors 
and officers, against all costs, charges, and expenses whatsoever incurred or 
sustained by him in connection with any action, suit, or proceeding to which 
he may be made a party by reason of his being or having been a director, 
officer, or employee of the Company or any of its subsidiaries or affiliates 
or his serving or having served any other enterprise as a director, officer, 
or employee at the request of the Company.  The Company shall cause to be 
maintained in effect for not less than six years from the Termination Date 
policies of directors' and officers' liability insurance of at least the same 
coverage as those policies, if any, maintained by the Company on the 
Termination Date or the date of the Change in Control and containing terms and

coverage is not available, the best available coverage for equal cost to the 
Company.
(B)     Legal Expenses.  In the event of any litigation, arbitration, or 
other proceeding between the Company and the Executive with respect to the 
subject matter of this Agreement or the enforcement of the Executive's rights

13.     REGISTRATION RIGHTS

(A)     Mandatory Registration under the Act.  Provided the Company is 
then a public company, promptly after the Company's receipt of a request, made 
by the Executive at any time during the Contract Term or prior to the third 
anniversary of the Termination Date, whichever is later, to register under the 
Securities Act of 1933 (the "Act"), at least 100,000 shares of Company common 
stock owned by Executive, to enable such Executive to make an underwritten or 
other public secondary offering thereof, the Company shall cause a 
registration statement  to be filed with the Securities and Exchange 
Commission (the "Commission") with respect to the number of such shares 
specified in the request, and shall use its best efforts to cause the 
registration statement to become effective.  The Company shall not be required 
to cause more than one registration statement to be filed pursuant to this 
Section 13(A).  The Company shall be entitled to include other securities of 
the Company to be offered either by the Company or other stockholders of the 
Company in any such registration statement; provided, however, that the 
Company or the holder or holders of other securities of the Company to be 
registered, as the case may be, shall agree to execute and deliver the 
underwriting agreement, if any, to be executed and delivered in connection 
with any such registration and the Executive requesting the registration shall 
have control of such registration and may require that any such other 
securities of the Company not be included in the registration statement if he 
is advised by the investment banking firm managing the underwriting that it 
reasonably believes that such inclusion would adversely affect the offering of 
the shares to be covered by the proposed registration statement.  The Company 
shall be entitled to postpone the filing of any such registration statement 
for a reasonable period of time if the Company is, at the time at which it 
receives any such request by Executive, conducting or is about to conduct, an 
offering of its securities, and the Company is advised by its investment 
banking firm that such offering would be adversely affected by the 
registration requested.
(B)    Inclusion in Other Registrations.  If, at any time during the 
period referred to in section 13(A) above, the Company shall determine or be 
required to register any shares of its common stock (whether on behalf of 
itself or any other person) under the Act on Forms S-1, S-2, S-3, SB-1, or SB-
2 (or if such forms are rescinded by the Commission, the forms which supplant 
such forms), excluding any registration for the offering and sale of 
securities of the Company to its employees, it will notify Executive in order 
that he may request that all or a part of the any shares of common stock owned 
by him be included in the registration statement.  If requested by the 
Executive in writing within 20 days after the Company's notice, the Company 
will include the requested number of shares in such registration statement.  
Any such request shall include the agreement of the Executive requesting the 
registration to execute and deliver the underwriting agreement, if any, to be 
executed and delivered in connection with such registration.  The Company may, 
however, decline to include all or a part of the requested number of shares in 
a registration statement pursuant to this section if it is advised by the 
investment banking firm managing the underwriting that such inclusion would 
adversely affect the offering of the shares to be covered by the proposed 
registration statement.
The Company shall use its best efforts to file such post-effective 
amendments to any registration statement described in this Section 13(B) as 
shall be necessary to keep it effective until six months after the effective 
date of the registration statement or the date on which all of the shares of 
the Purchasers covered thereunder shall have been sold, whichever is earlier. 
 
 As a condition to the Company's obligation under this Section 13(B) 
to cause a registration statement or amendment to be filed or shares to be 
included in a registration statement, the Executive shall provide such 
information and execute such documents as may reasonably be required in 
connection with such registration.  In addition, the Company shall not be 
required to include such shares in a registration statement if it shall have 
received opinions of its and the Executive's counsel to the effect that the 
proposed disposition of such shares may be effected without registration under 
the Act.

14.     GENERAL PROVISIONS

(A)     Determinations of Value.  Whenever, under this Agreement, it is 
necessary to determine whether one benefit is less than, equal to, or larger 
than another in value (whether or not such benefits are provided under this 
Agreement), such determination shall be made using the assumptions described 
in Section 9.

circumstances described below.

NOW, THEREFORE, the Company and the Executive hereby agree as

(ii) more than 35% of the Company's securities then entitled to vote 
in the election of directors shall be acquired by any "person" (as 
such term is used in Section 13(d) and 14(d) of the Securities 
Exchange Act of 1934, as amended); or


(iii) during any period of 24 consecutive months commencing on the 
Agreement Date, individuals who at the beginning of such period were 
members of the Board of Directors of the Company shall cease for any 
reason to constitute a majority of its Board of Directors.

activities.  The Executive is aware that reasonable performance objectives may 
be established by the Company's Board of Directors upon recommendation by the 
Chairman after consultation with the Executive, for Company-wide performance 
and for performance by the Executive.  The Executive agrees to work diligently 
throughout the Period of Employment to achieve any such performance objectives 
that shall then exist.
(C)     Principal Business Office.  During the Period of Employment, the 
Executive's principal business office shall be located in or near New Hope, 
Pennsylvania.

4.     RESTRICTIVE COVENANTS

(A)     Noncompetition.  The Executive agrees that during the Period of 
Employment and for the six-month period immediately following the Period of 
Employment, the Executive shall not, directly or indirectly, in any capacity, 
engage in any business which is substantially competitive with any business 
then actively conducted by the Company or any of its affiliates or 
subsidiaries, and the Executive shall not undertake to consult with or advise 
any such competitive business or otherwise, directly or indirectly, engage in 
any activity which is substantially competitive with or in any way adversely 
and substantially affects any activity of the Company or any of its affiliates 
or subsidiaries.
(B)     Nondisclosure.  Except as expressly provided herein, the 
Executive agrees that during the Period of Employment and thereafter, the 
Executive shall not make use of, disclose, divulge, or make accessible, to any 
third party, any information of a secret or confidential nature known to the 
Executive in the course of his employment with the Company or any of its 
affiliates or subsidiaries until such information has come into the public 
domain or has otherwise ceased to be secret or confidential.
(C)     Inventions.   All patentable and unpatentable inventions, 
discoveries, and ideas, which are made or conceived by the Executive during 
the term of this Agreement  shall be the Company's sole and exclusive property

or idea, the Executive will disclose it to the Company which shall have full 
power and authority to file and prosecute patent applications throughout the 
world thereon and to procure and maintain patents thereon.  The Executive 
shall, at the Company's request and expense, execute documents and perform 
such acts as counsel may deem advisable, to confirm in the Company all right, 
title, and interest throughout the world, in and to, such invention, 
discovery, or idea, and all patent applications, patents, and copyrights

(D)     Specific Performance and Injunctive Relief.  The Executive 
acknowledges and agrees that the Company or its affiliates and subsidiaries 
will suffer irreparable injury if the provisions of this Section 4 are not 
honored, that damages resulting from such injury will be incapable of being 
precisely measured, and that the Company and its subsidiaries and affiliates 
will not have an adequate remedy at law to redress the harm which such 
violation shall cause.  Accordingly, the Executive agrees that the Company 
shall have the rights and remedies of specific performance and injunctive 
relief, in addition to any other rights or remedies that may be available at 
law or in equity, in respect of any failure, or threatened failure, on the 
part of the Executive to comply with the provisions of this Section 4, 
including, but not limited to, temporary restraining orders and temporary 
injunctions to restrain any violation or threatened violation of this 
Agreement by the Executive.

5.     COMPENSATION, PERQUISITES, AND EMPLOYEE BENEFITS

(A)     Base Compensation.  For all substantially full time services 
rendered during the Period of Employment, the Executive shall receive annual 
base compensation at an initial rate of $60,000, which shall be increased, at 
least annually, in accordance with the Company's regular administrative 
practices generally applicable to its senior executives.  At the Agreement 
Date, such rate is acknowledged to be below the median base compensation as 
reported by industry surveys relating to private companies of equivalent size. 
 Upon a determination by the Board of Directors that the Company has obtained 
adequate initial financing, the Executive's base compensation shall be 
increased to not less than the median base compensation as reported by the 
most recent edition of Leadership in Biotechnology or any substantially 
equivalent compensation survey chosen by the Board of Directors, and 
thereafter, during the Period of Employment, shall not fall below such median 
as reported from time to time in such survey.  The Executive's base 
compensation shall never be less than the base compensation paid to any other 
senior management executive of the Company other than the Chairman.
(B)     Incentive Compensation.  During the Period of Employment, the 
Executive shall be and continue to be a full participant in the Company's 
Annual Bonus Plan and Stock Option Plans (the "Incentive Plans"), as the 
Incentive Plans are in effect from time to time with such improvements in the 
Incentive Plans or other incentive compensation plans as may from time to time 
be made in accordance with the practices of the Company.  The Executive shall 
be entitled to participate in any other incentive compensation plans generally 
available to senior executives of the Company.  If any of the Incentive Plans 
are terminated or discontinued, the Executive shall be entitled to participate 
in other incentive compensation plans with terms at least as favorable to the 
Executive as the Incentive Plans in effect prior to the termination or 
discontinuance of the Incentive Plans.
(C)     Perquisites.  During the Period of Employment, the Executive 
shall be entitled to one club membership to be used for business purposes, and 
shall be entitled to such other perquisites and fringe benefits, as shall be 
approved by the Board of Directors.  Upon a determination by the Board of 
Directors that the Company has obtained adequate initial financing, the 
Executive's perquisites shall include such perquisites generally available to 
officers of his rank at companies of equivalent size and status in the 
biotechnology industry, including without limitation a leased automobile, 
first class air travel, additional club memberships, supplemental retirement 
income, financial and legal counseling, and other perquisites.
(D)     Employee Benefits.  During the Period of Employment, the 
Executive shall be entitled to participate in all employee benefit plans and 
programs as in effect for senior executives of the Company ("Plans") under the 
terms of the Plans, with such improvements in the Plans as may from time to 
time be made in accordance with the practices of the Company.  The Executive 
shall be entitled to participate in any employee benefit plans and programs 
generally available to senior executives of the Company.  If any of the Plans 
are terminated or discontinued, the Executive shall be entitled to participate 
in other employee benefit plans with terms at least as favorable to the 
Executive as the Plans as in effect prior to the termination or discontinuance 
of the Plans.
(E)     Other Obligations of the Company.  Any increases in base and 
incentive compensation, perquisites or employee benefits under this Agreement 
or otherwise shall not diminish any other obligation of the Company hereunder.

6.     DEATH OR DISABILITY

(A)     Death.  If the Executive should die during the Period of 
Employment, his employment shall be deemed to have ceased on the last day of 
the month in which death shall have occurred.
(B)     Disability.  "Disability" shall mean an illness or accident 
which the Board of Directors determines in its discretion will or has 
prevented the Executive from performing his duties under this Agreement for a 
period of six consecutive months.  In the event that the Executive incurs a 
Disability during the Period of Employment, his employment shall be deemed to 
have ceased on the last day of such six-month period.

7.     TERMINATION

(A)     Cause.  Upon a determination by the Board of Directors, the 
Company shall have the right at any time to terminate the Executive's 
employment with the Company.  The termination of the Executive's employment by 
the Company during the Contract Term shall be deemed to be for "cause" only if 
such termination shall be the result of any of the following:

(i) an act or acts of dishonesty by the Executive resulting 
in conviction for a felony or conviction of a misdemeanor 
involving moral terpitude;

(ii) a deliberate and intentional failure by the Executive 
during the Period of Employment (except by reason of 
incapacity due to illness or accident) to comply with the 
provisions of this Agreement relating to the time and best 
efforts to be devoted by the Executive to the affairs of the 
Company; 

(iii) the Executive's gross misconduct, if such conduct 
results in demonstrably material injury to the Company; or

(iv)  following a unanimous vote of the Board of Directors (the 
Executive abstaining), the Board determines that the Executive 
materially failed to meet the resonable performance objectives 
established by the Board for Company-wide performance and for 
performance by the Executive;

provided that notice of such termination is given in accordance with Section 
7(C) below.
(B)     Good Reason.  The Executive shall have the right at any time to 
terminate his employment with the Company.  Termination by the Executive shall 
be deemed to be for "Good Reason" only if such termination shall be the result 
of the following:
(i) a reduction during the Period of Employment in the 
current level of the Executive's aggregate compensation, 
including his annual base compensation, Annual Bonus Plan 
awards, Stock Option Plan awards, employee benefit plan 
coverages, and perquisites (other than a reduction in awards 
or benefits that is generally applicable to participants in 
a plan in accordance with the terms of the plan); 

(ii) a diminishment during the Period of Employment in the 
Executive's position, powers, authority, duties, or 
responsibilities, or the business to which those powers, 
authority, duties, or responsibilities apply; removal during 
the Period of Employment of the Executive from the highest 
office held on or after the Agreement Date; or change during 
the Period of Employment in the Executive's chain of 
supervision as it existed as of the Agreement Date (unless 
as a result of, and only during, Executive's Disability); or 
 

(iii) a material beach of this Agreement by the Company;

provided that notice of the Executive's election to terminate his employment 
under this Agreement is given in accordance with Section 7(C) below.  Failure 
to elect to terminate with respect to one event giving rise to Good Reason 
does not preclude the Executive from making the election with respect to a 
subsequent event.
(C)     Termination Procedure.
(1)     Notice.     
(a)  Notice of termination of employment under this Agreement 
shall be provided in writing by the Company or the Executive, as applicable,

employment, the Executive shall provide to the Company the notice described in

be given, except in the case of a continuing breach, within three calendar 
months after the most recent event giving rise to Good Reason.
(2)     Cure.          
(a)  In the case of the Executive's alleged breach or gross 
misconduct set forth in Sections 7(A)(ii) or (iii), the Executive shall be

30 days from his receipt of the notice referred to above, or take all 
reasonable steps to that end during such 30-day period and thereafter.
(b)  In the case of the Executive's allegation of Good Reason, the 
Company shall be given the opportunity to remedy the alleged Good Reason 
within 30 days from its receipt of the notice referred to above, or take all 
reasonable steps to that end during such 30-day period and thereafter.
(3)     Arbitration.  In the event that the Executive's employment 
shall be terminated by the Company and such termination is alleged to be for 
Cause, the Executive shall have the right, in addition to all other rights and 
remedies provided by law or equity, to seek arbitration as described below.  
In the event that the Executive's employment shall be terminated by the

calendar year prior to the Termination Date (or, in the case of Disability, 
the earlier of the Termination Date and the Expiration Date).
(4)     Reduction of Payments.  The amount of any payments due under 
this Section 8(B) shall be reduced by any payments to which the Executive is

registered, as the case may be, shall agree to execute and deliver the 
underwriting agreement, if any, to be executed and delivered in connection 
with any such registration and the Executive requesting the registration shall 
have control of such registration and may require that any such other 
securities of the Company not be included in the registration statement if he 
is advised by the investment banking firm managing the underwriting that it 
reasonably believes that such inclusion would adversely affect the offering of 
the shares to be covered by the proposed registration statement.  The Company 
shall be entitled to postpone the filing of any such registration statement 
for a reasonable period of time if the Company is, at the time at which it 
receives any such request by Executive, conducting or is about to conduct, an 
offering of its securities, and the Company is advised by its investment 
banking firm that such offering would be adversely affected by the 
registration requested.
(B)    Inclusion in Other Registrations.  If, at any time during the 
period referred to in section 13(A) above, the Company shall determine or be 
required to register any shares of its common stock (whether on behalf of 
itself or any other person) under the Act on Forms S-1, S-2, S-3, SB-1, or SB-
2 (or if such forms are rescinded by the Commission, the forms which supplant 
such forms), excluding any registration for the offering and sale of 
securities of the Company to its employees, it will notify Executive in order 
that he may request that all or a part of the any shares of common stock owned 
by him be included in the registration statement.  If requested by the 
Executive in writing within 20 days after the Company's notice, the Company 
will include the requested number of shares in such registration statement.  
Any such request shall include the agreement of the Executive requesting the 
registration to execute and deliver the underwriting agreement, if any, to be 
executed and delivered in connection with such registration.  The Company may, 
however, decline to include all or a part of the requested number of shares in 
a registration statement pursuant to this section if it is advised by the 
investment banking firm managing the underwriting that such inclusion would 
adversely affect the offering of the shares to be covered by the proposed 
registration statement.
The Company shall use its best efforts to file such post-effective 
amendments to any registration statement described in this Section 13(B) as 
shall be necessary to keep it effective until six months after the effective 
date of the registration statement or the date on which all of the shares of 
the Purchasers covered thereunder shall have been sold, whichever is earlier. 
 
 As a condition to the Company's obligation under this Section 13(B) 
to cause a registration statement or amendment to be filed or shares to be 
included in a registration statement, the Executive shall provide such 
information and execute such documents as may reasonably be required in 
connection with such registration.  In addition, the Company shall not be 
required to include such shares in a registration statement if it shall have 
received opinions of its and the Executive's counsel to the effect that the 
proposed disposition of such shares may be effected without registration under 
the Act.

enforcement of this Agreement shall be governed by the laws of the State of 
Florida, without giving effect to the principles of conflict of laws thereof.

The Committee, in its absolute discretion, shall determine the effect of all 
other matters and questions relating to Termination of Employment, including 
without limitation, the question of whether a particular leave of absence 
constitutes a Termination of Employment; provided, however, that, with respect 
to Incentive Stock Options, a leave of absence shall constitute a Termination 
of Employment if, and to the extent that, such leave of absence interrupts 
employment for the purposes of Section 422(a)(2) of the Code and the then 
applicable regulations and revenue rulings under said Section.

expressly reserved, to remove any such person at any time for any reason

which may be issued upon exercise of option granted to Directors and Members 
of the Scientific Advisory Board shall not exceed 75,000.

     3.2     Types of Awards.  Options granted under the Plan may be intended 
to qualify for favorable tax treatment as Incentive Stock Options, and as 
Nonqualified Options, being those not qualified or intended for such favorable 
tax treatment under the Code.

without having been fully exercised, additional Options for the number of 
shares of Common Stock that would have been issued upon exercise of such 
Option may be re-granted under this Plan, subject to limitations of Section 
3.1.

     3.4     Changes in Company Capitalization.  In the event that (i) the 
outstanding shares of Common Stock are hereafter changed into or exchanged for 
a different number or kind of shares or other securities of the Company, or of 
another entity, by reason of reorganization, merger, consolidation, 
recapitalization, reclassification, or (ii) the number of shares is increased 
or decreased by reason of a stock split, stock dividend, combination of shares 
or any other increase or decrease in the number of such shares of Common Stock 
effected without receipt of consideration by the Company (provided, however, 
that conversion or exchange of any convertible or exchangeable securities of 
the Company shall not be deemed to have been "effected without receipt of 
consideration"), then the Committee shall make appropriate adjustments in the 
number and kind of shares for the purchase of which options may be granted, 
including adjustments to the limitations in Section 3.1 on the maximum number 
and kind of shares which may be issued on exercise of an Option.

4.     Granting of Options.

     4.1     Eligibility.  Any Officer or other key Employee of the Company 
and any Outside Director, Consultant, or Member of the Scientific Advisory 
Board shall be eligible to be granted Options.  Each Outside Director, 
including a member of the Committee, each Member of the Scientific Advisory 
Board, and each Consultant shall be eligible to be granted only Nonqualified 
Options.

     4.2     Incentive Stock Options.     No Incentive Stock Option shall be 
granted unless it qualifies as an "incentive stock option" under Section 422 
of the Code when granted.

     4.3     Grants.  (a)

          (a)     The Committee shall from time to time, in its absolute 
discretion:

               (i)     Determine which Employees are key Employees, taking 
into account the nature of the services rendered by the particular Employee, 
the Employee's potential contribution to the long-term success of the Company, 
and such other factors as the Committee deems relevant, and select from among 
the key Employees (including those to whom Options have been previously 
granted under the Plan, Outside Directors who are not members of the 
Committee, Consultants, and Members of the Scientific Advisory Board, such of 
them as in its opinion should be granted Options; and

               (ii)     Determine the number of shares to be subject to such 
Options granted to such selected individuals, and determine whether such 
Options are to be Incentive Stock Options or Nonqualified Options; and

               (iii)     Determine the terms and conditions of such Options. 

          (b)     Upon the selection of such individual to be granted an 
Option, the Committee shall instruct the Secretary to issue such Option and 
may impose such conditions on the grant of such Option as it deems 
appropriate.  Without limiting the generality of the preceding sentence, the 
Committee may, in its discretion and on such terms as it deems appropriate, 
require as a condition of the grant of an Option to an individual that the 
individual surrender for cancellation some or all of the unexercised Options 
which have been previously granted to him.  An Option, the grant of which is 
conditioned upon such surrender, may have an Option price lower (or higher) 
than the Option price of the surrendered Option, may cover the same (or a 
lesser or greater) number of shares as the surrendered Option, may contain 
such other terms as the Committee deems appropriate and shall be exercisable 
in accordance with its terms, without regard to the number of shares, price, 
Option period or any other term or condition of the surrendered Option.

     4.4     Granting of Nonqualified Options to Outside Directors.

          (a)     Each person who is an Outside Director of the Company at the 
date of the adoption of this Plan shall be granted Nonqualified Options to 
purchase 2,000 shares of Common Stock.

               The Committee  shall grant to each Outside Director annually 
(so long as he or she is an Outside Director on each such anniversary date) 
Nonqualified Options to purchase an additional 2,500 shares of Common Stock.

     4.5     Administration of the Plan.

          (a)     The Plan shall be administered by the Committee.  The 
Committee shall consist of at least two Outside Directors (if there are such) 
selected by the Board of Directors, one of whom, if possible, shall be a 
Disinterested Person.  Committee members may resign by delivering written 
notice to the Secretary.  Vacancies on the Committee shall be filled by the 
Board of Directors.

          (b)     Except as otherwise provided in the Plan and except as 
otherwise expressly stated to the contrary in the Company's Certificate of 
Incorporation, Bylaws, or elsewhere, the Committee shall have the sole 
discretionary authority (i) to select the Officers, other key Employees, 
Directors, Consultants, or Members of the Scientific Advisory Board who are to 
be granted Options under the Plan, (ii) to determine the number of Options to 
be granted to any person at any time, (iii) to authorize the granting of 
Options, (iv) to impose such conditions and restrictions on Options as it 
determines appropriate, (v) to interpret the Plan and the Options, (vi) to 
prescribe, amend and rescind rules and regulations relating to the Plan, and 
(vii) to take any other actions in connection with the Plan and to make all 
determinations under the Plan as it may deem necessary or advisable for the 
administration of the Plan.  The determinations of the Committee on the 
matters referred to in this Section 4 shall be binding and conclusive on all 
persons.

          (c)     A majority of the members of the Committee shall constitute 
a quorum.  All determinations of the Committee shall be made by a majority of 
its members.  Any decision or determination reduced to writing and signed by 
all of the members of the Committee shall be fully effective as if it had been 
made by a majority vote at a meeting duly called and held.

          (d)     The Committee may delegate to one or more persons any of its 
powers, other than its power to authorize the granting of Options, or 
designate one or more persons to do or perform those matters to be done or 
performed by the Committee, including administration of the Plan.  Any person 
or persons delegated or designated by the Committee shall be subject to the 
same obligations and requirements imposed on the Committee and its members 
under the Plan.

          (e)     Members of the Committee shall receive such compensation for 
their services as members as may be determined by the Board of Directors.  All 
expenses and liabilities incurred by members of the Committee in connection 
with the administration of the Plan shall be borne by the Company.  The 
Committee may employ attorneys, consultants, accountants, appraisers, brokers, 
or other persons.  The Committee, the Company, and its Officers and Directors 
shall be entitled to rely upon the advice, opinions, or valuations of any such 
persons.  All elections taken and all interpretations and determinations made 
by the Committee in good faith shall be final and binding upon all Optionees, 
the Company, and all other interested persons.  No member of the Committee 
shall be personally liable for any action, determination or interpretation 
made in good faith with respect to the Plan.  Members of the Committee and 
each person or persons designed or delegated by the Committee shall be 
entitled to indemnification by the Company for any action or any failure to 
act in connection with services performed by or on behalf of the Committee for 
the benefit of the Company to the fullest extent provided or permitted by the 
Company's Certificate of Incorporation, Bylaws, any insurance policy or other 
agreement intended for the benefit of the Committee, or by any applicable law.

5.     Terms of Options.

     5.1     Option Agreement.     Each Option shall be evidenced by a written 
Stock Option Agreement, which shall be executed by the Optionee and an 
authorized Officer of the Company and which shall contain such terms and 
conditions as the Committee shall determine, consistent with the Plan.  Stock 
Option Agreements evidencing Incentive Stock Options shall contain such terms 
and conditions as may be necessary to qualify such Options as "incentive stock 
options" under Section 422 of the Code.

     5.2     Vesting of Options.
          (a)     Options granted to Outside Directors in accordance with 
Section 4.4 hereof shall vest 20% at the end of the first year of service 
after the grant and 1/12 of 20% for each month thereafter.  All other Options 
granted under the Plan shall vest as determined by the Committee and as set 
forth in the respective Stock Option Agreement, whether such vesting is based 
on the attainment of performance goals, chronologically, or otherwise.

          (b)     Options which have been granted but not yet vested under 
this Section 5.2 shall be forfeited if the Optionee dies, becomes disabled, or 
leaves the employment of the Company, its subsidiary, or affiliated entity for 
any or no reason, with or without cause, or otherwise, unless provided to the 
contrary in any agreement approved by the Committee between the Optionee and 
the Company, its subsidiary, or affiliated entity, which agreement shall 
govern any further vesting of Options.

     5.3     Option Exercise Price.

          (a)     The price per share for Options granted pursuant to Section 
4.3 shall be set by the Committee; provided, however, that the price per share 
shall be not less than 100% of the Fair Market Value of such shares on the 
date such Option is granted; provided, further, that, in the case of an 
Incentive Stock Option, the price per share shall not be less than 110% of the 
Fair Market Value of such shares on the date such Option  is granted in the 
case of an individual then owning (within the meaning of Section 424(d) of the 
Code) more than 10% of the total combined voting power of all classes of stock 
of the Company or any subsidiary of the Company.

          (b)     The price of shares subject to each Nonqualified Option 
granted pursuant to Section 4.4 shall be the Fair Market Value of such shares 
on the date such Option is granted.

     5.4     Exercise Periods.

          (a)     No Option may be exercised in whole or in part until it has 
vested, except as may be provided in Sections 5.4(c) or 5.6 or as may 
otherwise be provided for in a Stock Option Agreement which has been approved 
by the Committee.

          (b)     Subject to the provisions of Sections 5.2, 5.4(c), 5.4(d) 
and 5.6, Options shall become exercisable at such times and in such 
installments (which may be cumulative) as the Committee shall provide in the 
terms of each individual Stock Option Agreement; provided, however, that by 
resolution adopted after an Option is granted the Committee may, on such terms 
and conditions as it may determine to be appropriate and subject to Sections 
5.2, 5.4(c), 5.4(d) and 5.6, accelerate the time at which such Option or any 
portion thereof may be exercised, or such rights may be set forth in an 
agreement between the Optionee and the Company which has been approved by the 
Committee.

          (c)     No portion of an Option which is unexercisable at 
Termination of Employment shall thereafter become exercisable; provided, 
however, that provision may be made that such Option shall become exercisable 
in the event of a Termination of Employment as may be determined by the 
Committee, or such rights may be set forth in an agreement between the 
Optionee and the Company which has been approved by the Committee.

          (d)     To the extent the aggregate Fair Market Value of Common 
Stock with respect to which Incentive Stock Options (within the meaning of 
Section 422 of the Code, but without regard to Section 422(d) of the Code) are 
exercisable for the first time by an Optionee during any calendar year (under 
the Plan and all other incentive stock option plans of the Company) exceeds 
$100,000, such options shall be treated as Nonqualified Options.  The rule set 
forth in the preceding sentence shall be applied by taking Options into 
account in the order in which they were granted.  For purposes of this Section 
5.4(d), the Fair Market Value of Common Stock shall be determined as of the 
time the Option with respect to such Common Stock is granted.

          (e)     No Option may be exercised to any extent by anyone after the 
first to occur of the following events:

               (i)     In the case of an Incentive Stock Option:

                    (A)     the expiration of ten years from the date the 
Option was granted; 

                    (B)     in the case of an Optionee owning (within the 
meaning of Section 424(d) of the Code), on the Date of Grant, more than 10% of 
the total combined voting power of all classes of stock of the Company or any 
subsidiary of the Company, the expiration of ten years from the date the 
Option was granted; 

                    (C)     except in the case of any Optionee who is disabled 
(within the meaning of Section 22(a)(3) of the Code), the expiration of three 
months from the date of the Optionee's Termination of Employment for any 
reason other than such Optionee's death unless the Optionee dies within said 
three-month period; 

                    (D)     in the case of an Optionee who is disabled (within 
the meaning of Section 22(a)(3) of the Code), the expiration of one year from 
the date of the Optionee's Termination of Employment for any reason other than 
such Optionee's death unless the Optionee dies within said one-year period; 

                    (E)     the expiration of one year from the date of the 
Optionee's death.

               (ii)     In the case of a Nonqualified Option:

                    (A)     the expiration of ten years and one day from the 
date the Option was granted; or
                    (B)     the expiration of one year from the date of the 
Optionee's Termination of Employment (whether by death or otherwise).

          (f)     Subject to the provisions of Section 5.4(a), the Committee 
shall provide, in terms of each individual stock Option Agreement when such 
Option expires and when it becomes unexercisable, and (without limiting the 
generality of the foregoing) the Committee may provide in the terms of 
individual Stock Option Agreements that said Options expire immediately upon a 
Termination of Employment; provided, however, that provision may be made that 
such options shall become exercisable in the event of a Termination of 
Employment because of the Optionee's retirement, death, disability, or as may 
otherwise be determined by the Committee.

     5.5     Adjustments in outstanding Options.     In the event that the 
outstanding shares of Common Stock subject to Options are changed into or 
exchanged for a different number or kind of shares of the Company or other 
securities of the Company by reason  of merger, consolidation, 
recapitalization, reclassification, or the number of shares is increased or 
decreased by reason of a stock split, stock dividend, combination of shares or 
any other increase or decrease in the number of such shares of Common Stock 
effected without receipt of consideration by the Company (provided, however, 
that conversion of  any convertible securities of the Company shall not be 
deemed to have been "effected without receipt of consideration"), the 
Committee shall make appropriate adjustments in the number and kind of shares 
as to which all outstanding Options, or portions thereof then unexercised, 
shall be exercisable, to the end that after such event the Optionee's 
proportionate interest shall be maintained as before the occurrence of such 
event.  Such adjustment in an outstanding Option shall be made without change 
in the total price applicable to the Option or the unexercised portion of the 
Option (except for any change in the price resulting from rounding-off share 
quantities or prices) and with any necessary corresponding adjustment in 
Option price per share; provided, however, that, in the case of Incentive 
Stock Options, each such adjustment shall be made in such manner as not to 
constitute a "modification" within the meaning of Section 424(h)(3) of the 
Code.  Any such adjustment made by the Committee shall be final and conclusive 
upon all Optionees, the Company, and all other interested persons.

     5.6     Change of Control, Merger, Consolidation, Acquisition, 
Liquidation or Dissolution.  Notwithstanding the provisions of Section 5.5, in 
its absolute discretion, and on such terms and conditions as it deems 
appropriate, the Committee may provide by the terms of any Option that such 
Option cannot be exercised after a change of control or the merger or 
consolidation of the Company with or into another entity, the acquisition by 
another entity (excluding any employee benefit plan of the Company or any or 
other fiduciary holding securities under an employee benefit plan of the 
Company) of all or substantially all of the Company's assets or 51% or more of 
the Company's then outstanding voting stock, or the liquidation or dissolution 
of the Company, and if the Committee so provides, it may, in its absolute 
discretion and on such terms and conditions as it deems appropriate, also 
provide, either by the terms of such Option or by a resolution adopted prior 
to the occurrence of such change of control, merger, consolidation, 
acquisition, liquidation or dissolution, that, for some period of time prior 
to such event, such Option shall be exercisable as to all shares covered 
thereby, notwithstanding anything to the contrary in Section 5.4(a), Section 
5.4(b) and/or any installment provision of such Option; and if the Committee 
so provides, it may, in its absolute discretion and on such terms and 
conditions as it deems appropriate, also consent to, cause or otherwise 
effectuate an assumption, assignment, or other transfer of the Plan and any 
outstanding Stock Option Agreements by or to the successor entity.

     5.7     No Right to Continued Employment.  Nothing in this Plan or in any 
Stock Option Agreement issued hereunder shall confer upon any Optionee any 
right to continue in the employ of the Company or its subsidiaries or shall 
interfere with or restrict in any  way the rights of the Company, and its 
subsidiaries, which are hereby expressly reserved, to terminate or discharge 
any optionee at any time for any reason whatsoever, with or without cause.

6.     Exercise of Options.

     6.1     Person Eligible to Exercise.  During the lifetime of the 
Optionee, only such Optionee may exercise an Option (or any portion thereof) 
granted to such Optionee.  After the death of the Optionee, any exercisable 
portion of an Option may, prior to the time when such portion becomes 
unexercisable under the Plan or the applicable Stock Option Agreement, be 
exercised by the personal representative of such Optionee or by any person 
empowered to do so under the deceased Optionee's will or under the then 
applicable laws of descent and distribution.

     6.2     Partial Exercise.  At any time and from time to time prior to the 
time when any exercisable Option or exercisable portion thereof becomes 
unexercisable under the Plan or the applicable Stock Option Agreement, such 
Option or portion thereof may be  exercised in whole or in part; provided, 
however, that the Company shall not be required to issue fractional shares and 
the Committee may, by the terms of the Stock Option Agreement, require any 
partial exercise to be with respect to a specified minimum number of shares.

     6.3     Manner of Exercise.  An exercisable Option, or any exercisable 
portion thereof, may be exercised solely by delivery to the Secretary of all 
of the following prior to the time when such Option or such portion becomes 
unexercisable under the Plan or the applicable Stock Option Agreement:

          (a)     Notice in writing signed by the Optionee or other person 
then entitled to exercise such Option or portion stating that such Option or 
portion is exercised, such notice complying with all applicable rules 
established by the Committee; and

          (b)     either:

               (i)     Full payment (in cash or by check) for the shares with 
respect to which such Option or portion is thereby exercised; or

               (ii)     With the consent of the Committee, (A) shares of the 
Company's Common Stock owned by the Optionee duly endorsed for transfer to the 
Company, or (B) subject to the timing requirements of Section 6.4, shares of 
the Company's Common Stock issuable to the Optionee upon exercise of the 
Option, with a Fair Market Value on the date of Option exercise equal to the 
aggregate Option price of  the shares with respect to which such Option or 
portion is thereby exercised; or

               (iii)     With the consent of the Committee, a full recourse 
promissory note bearing interest (at least at such rate as shall then preclude 
the imputation of interest under the Code or any successor provision) and 
payable upon such terms as may be prescribed by the Committee.  The Committee 
may also prescribe the form of such note and the security to be given for such 
note.  No Option may, however, be exercised by delivery of a promissory note 
or by a loan from the Company when or where such loan or other extension of 
credit is prohibited by law; or 

               (iv)     With the consent of the Committee, any combination of 
the consideration provided in the foregoing subsections (i), (ii) and (iii); 
and

          (c)     The payment of the Company (or other employer) of all 
amounts which it is required to withhold under federal, state or local law in 
connection with the exercise  of the Option; with the consent of the 
Committee, (i) shares of the Company's Common Stock owned by the Optionee duly 
endorsed for transfer, or (ii) subject to the timing requirements of Section 
6.4, shares of the Company's Common Stock issuable to the Optionee upon 
exercise of the Option, valued at Fair Market Value as of the date of Option 
exercise, may be used to make all or part of such payment; and

          (d)     Such representations and documents as the Committee, in its 
absolute discretion, deems necessary or advisable to effect compliance with 
all applicable  provisions of the Securities Act and any other federal or 
state securities laws or  regulations.  The Committee may, in its absolute 
discretion, also take whatever additional actions it deems appropriate to 
effect such compliance including without limitation, placing legends on share 
certificates and issuing stop-transfer orders to transfer agents and 
registrars; and

          (e)     In the event that the Option or portion thereof shall be 
exercised pursuant to Section 6.1 by any person or persons other than the 
Optionee, appropriate proof of the right of such person or persons to exercise 
the Option or portion thereof.

     6.4     Timing Requirements.  Shares of the Company's Common Stock 
issuable to the Optionee upon exercise of the Option may be used to satisfy 
the Option price or the
tax withholding consequences of such exercise only (i) during the period 
beginning on the third business day following the date of release of the 
quarterly or annual summary statement of sales and earnings of the Company and 
ending on the twelfth business day following such date, or (ii) pursuant to an 
irrevocable written election by the Optionee to  use shares of the Company's 
Common Stock issuable to the Optionee upon exercise of  the Option to pay all 
or part of the Option price or the withholding taxes (subject to the approval 
of the Committee) made at least six months prior to the payment of such option 
price or withholding taxes.
     6.5     Conditions to Issuance of Stock Certificates.  The shares of 
Common Stock issuable and deliverable upon the exercise of an Option, or any 
portion thereof, may be either previously authorized but unissued shares or 
issued shares which have then been reacquired by the Company.  The Company 
shall not be required to issue or deliver any certificate or certificates for 
shares of Common Stock purchased upon the exercise of any Option or portion 
thereof prior to fulfillment of all of the following conditions:

          (a)     The obtaining of any approval or other clearance from any 
state or federal governmental agency which the Committee shall, in its 
absolute discretion determine to be necessary or advisable; and 

          (b)     The payment to the Company (or other employer corporation) 
of all amounts which it is required to withhold under federal, state or local 
law in connection with the exercise of the Option; and

          (c)     The lapse of such reasonable period of time following the 
exercise of the Option as the Committee may establish from time to time for 
reasons of administrative convenience.

     6.6     No Rights as Stockholders.  The holders of Options shall not be, 
nor have  any of the rights or privileges of, stockholders of the Company in 
respect to any shares purchasable upon the exercise of any part of an Option 
unless and until certificates representing such shares have been issued by the 
Company to such holders.  Except in accordance with Section 3.4 hereof, no 
adjustment shall be made for dividends (ordinary or extraordinary, whether 
cash or other property) or distributions or other rights for which the record 
date is prior to the date on which the exercise price has been received by the 
Company and shares have been issued.

     6.7     Transfer Restrictions.  Unless otherwise approved in writing by 
the Committee, no shares of Common Stock acquired upon exercise of any Option 
by any Officer or Director may be sold, assigned, pledged, encumbered, or 
otherwise transferred until at least six months have elapsed from (but 
excluding) the date that such Option was exercised.  The Committee, in its 
absolute discretion, may impose such other restrictions on the transferability 
of the shares purchasable upon the exercise of an Option as it deems 
appropriate.  Any such other restriction shall be set forth in the respective 
Stock Option Agreement and may be referred to on the certificates evidencing 
such shares.  The Committee may require any Optionee to give the Company 
prompt notice of any  disposition of shares of stock, acquired by exercise of 
an Incentive Stock Option, within  two years from the date of granting such 
Option or one year after the transfer of such shares to such optionee.  The 
Committee may direct that the certificates evidencing shares acquired by 
exercise of an Option refer to such requirement to give prompt notice of 
disposition.

7.     Additional Provisions. 

     7.1     Approval of Plan by Stockholders.  This Plan will be submitted 
for the approval of the Company's stockholders within twelve months before or 
after the date of the Board of Director's initial adoption of the Plan.  
Options may be granted prior to such stockholder approval; provided, however, 
that such Options shall not be exercisable prior to the time when the Plan is 
approved by the stockholders; provided, further, that if such approval has not 
been obtained at the end of said twelve-month period, all Options previously 
granted under the Plan shall thereupon be canceled and become null and void.  
The Company shall take such actions with respect to the Plan as may be 
necessary to satisfy the requirements of Rule 16b-3(b).

     7.2     Nontransferability.  No Option or interest or right therein or 
part thereof shall be liable for the debts, contracts or engagements of the 
Optionee or his successors in interest or shall be subject to disposition by 
transfer, alienation, anticipation, pledge, encumbrance, assignment or any 
other means whether such disposition be voluntary or involuntary or by 
operation of law by judgment, levy, attachment, garnishment or any other legal 
or equitable proceedings (including bankruptcy and divorce proceeding), and 
any attempted disposition thereof shall be null and void and of no effect; 
provided, however, that nothing in this Section 7.2 shall prevent transfers by 
will or by the applicable laws of descent and distribution.

     7.3     Securities Act.  Upon issuance of Common Stock of the Company to 
the Participant, or his heirs, the recipient of that stock shall represent 
that the shares of stock are taken for investment and not resale and shall 
make such other representations as may be necessary to qualify the issuance of 
the shares as exempt from the Securities Act and applicable federal and state 
securities laws and regulations, or to permit registration of the shares and 
shall represent that he or she shall not dispose of those shares in violation 
of the Securities Act or of applicable federal and state securities laws and 
regulations.  The Company reserves the right to place a legend on any stock 
certificate issued pursuant to the Plan to assure compliance with this Section 
and with the vesting requirements of Section 5.2.  No shares of Common Stock 
of the Company shall be required to be distributed until the Company shall 
have taken such action, if any, as is then required to comply with the 
provisions of the Securities Act or any other then applicable federal or state 
securities law or regulation.

     7.4     Withholding of Tax.  The Company shall have the right to deduct 
from any payment made under the Plan any federal, state or local income or 
other taxes required  by law to be withheld with respect to such payment.  It 
shall be a condition to the obligation of the Company to deliver Common Stock 
upon exercise of an Option that the Optionee pay to the Company such amount as 
may be requested by the Company for the purpose of satisfying any liability 
for such withholding taxes.  Any grant under this Plan may provide by its 
terms that the Optionee may elect, in accordance with any applicable 
regulations,  to pay a portion or all of the amount of such minimum required 
or additional permitted withholding taxes in shares of Common Stock, subject 
to the timing restrictions set forth in Section 6.4 hereof.  The Optionee 
shall authorize the Company to withhold, or shall     agree to surrender back 
to the Company, on or about the date such withholding tax liability is 
determinable, shares of Common Stock previously owned by such Optionee or a 
portion of the shares that were or otherwise would be distributed to such 
Optionee pursuant to such award having a Fair Market Value equal to the amount 
of such required or permitted withholding taxes to be paid in shares.

     7.5     Termination and Amendment of Plan.  The Committee may at any time 
suspend or terminate the Plan, or make such modifications of the Plan as it 
shall deem advisable, provided that the Plan not be changed to increase the 
cost of the Plan to the Company.  However, without approval of the Company's 
stockholders given within twelve (12) months before or after the action by the 
Committee, no action of the Committee may, except as provided in Section 3.4, 
increase any limit imposed in Section 3.1 on the maximum number of shares 
which may be issued upon exercise of Options, materially modify the 
eligibility requirements of Section 4.1, reduce the minimum Option price 
requirements of Section 5.3, extend the limit imposed on this Section 7.5 on 
the period during which Options may be granted or amend or modify the Plan in 
a manner requiring stockholder approval under Rule 16b-3.  Notwithstanding 
anything to the contrary  contained herein, the Committee shall not amend or 
modify the Plan more than once every six (6) months or in any other manner 
inconsistent with the requirements of Rule 16b-3(c)(2)(ii) except to the 
extent required by changes in the Code, the Employee Retirement Income 
Security Act of 1974, or regulations and rules issued thereunder.  No 
termination or amendment of the Plan may, without the consent of a 
Participant, adversely affect the rights of such Participant notwithstanding 
anything to the contrary herein.  No Option may be granted during any period 
of suspension of the Plan nor after termination of the Plan, and in no event 
may any Option be granted under this Plan after the first to occur of the 
following events:

          (a)     The expiration of ten years from the date the Plan is 
adopted by the Board of Directors; or

          (b)      The expiration of ten years from the date the Plan is 
approved by the Company's stockholders under Section 7.1.

     7.6     Duties of the Company.  The Company shall, at all times during 
the term of each Option, reserve and keep available for issuance or delivery 
such number of shares of Common Stock as will be sufficient to satisfy the 
requirements of all Options at the time outstanding, shall pay all original 
issue taxes with respect to the issuance or delivery of shares pursuant to the 
exercise of such Option and all other fees and expenses  necessarily incurred 
by the Company in connection therewith.

     7.7     Absence of a Committee.  Should the Board of Directors fail to 
appoint the Committee or should there be no Committee for any other reason, 
then the Plan shall be administered by the Board of Directors.  All action 
with respect to Options granted to any Officer or key Employee who is subject 
to Section 16 of the Exchange Act shall be taken by the Board of Directors if 
each member is a Disinterested Person, or if the entire Board of Directors is 
not comprised of Disinterested Persons, then by not less than two of the 
Directors who are Disinterested Persons.  In the absence of a Committee, the 
Board of Directors (or that portion thereof comprised in accordance with this 
Section 7.7) shall have all the powers of the Committee as set forth herein in 
administration of the Plan.

     7.8     Effective Date of Plan.  In accordance with Section 7.5 hereof, 
the effective date of the Plan will be the date on which it was approved by 
the stockholders of the Company.  The Plan was adopted by the Board of 
Directors, subject to stockholder approval on August 31, 1994.

8.     General Provisions.

     8.1     No Rights.  No Employee shall have any claim or right to be 
granted Options under the Plan.  Neither the adoption and maintenance of the 
Plan nor the granting of Options pursuant to the Plan shall be deemed to 
constitute a contract of employment between the Company and any Employee or to 
be a condition of the employment of any person.  The Plan and any Options 
granted under the Plan shall not confer upon any Participant any right with 
respect to continued employment by the Company, nor shall they interfere in 
any way with the right of the Company to terminate the employment of any 
Participant at any time, and for any reason, with or without cause, it being 
acknowledged, unless expressly provided otherwise in writing, that the 
employment of any Participant is "at will".

     8.2     Costs of Administration.  The Company shall pay all costs and 
expenses of administering the Plan.

     8.3     Controlling Laws.  The granting of Options and the issuance of 
shares of Common Stock under the Plan shall be subject to all applicable laws, 
rules and regulations, and to such approvals by any governmental agencies or 
national securities exchanges as may be required.  The provisions of this Plan 
shall be interpreted so as to comply with the conditions and requirements of 
the Securities Act, the Exchange Act, and rules and regulations issued 
thereunder, including without limitation Rule 16b-3, unless a contrary 
interpretation of any such provisions otherwise required by applicable law.  
Except to the extent preempted by Federal law, this Plan and all Stock Option 
Agreements entered into pursuant hereto shall be construed and enforced in 
accordance with, and governed by, the laws of the State of Delaware, 
determined without regard to its conflict of laws rules.

     8.4     No Obligation to Exercise.  The granting of an Option shall 
impose no obligation upon the Optionee to exercise such Option.

     8.5     Language.  Whenever the context so indicates, the singular or 
plural number, and the masculine, feminine or neuter gender shall each be 
deemed to include the other.

     8.6     No Employment Contract.  The Plan is not a contract of 
employment, and the terms of employment of any recipient of any award 
hereunder shall not be affected in any way by the Plan or related instruments 
except as specifically provided therein.  The establishment of the Plan shall 
not be construed as conferring any legal rights upon any recipient of any 
award hereunder for a continuation of employment, nor shall interfere with the 
right of the Company or any subsidiary to discharge any recipient of any award 
hereunder and to treat him or here without regard to the effect with such 
treatment might have upon him or her as the recipient of any award hereunder.

     8.7     No Rights as Stockholder.  No Optionee of any Option shall have 
any rights as a stockholder with respect to any shares subject to his or her 
Option prior to the date on which he or she is recorded as the holder of such 
shares on the records of the Company.  No Optionee of any Option shall have 
the rights of a stockholder until he or she has paid in full the Option price.

administration of the Plan.  The determinations of the Committee on the 
matters referred to in this Section 4 shall be binding and conclusive on all 
persons.

          (c)     A majority of the members of the Committee shall constitute 
a quorum.  All determinations of the Committee shall be made by a majority of

failure to act in connection with services performed by or on behalf of the 
Committee for the benefit of the Company to the fullest extent provided or 
permitted by the Company's Certificate of Incorporation, Bylaws, any insurance 
policy, or other agreement intended for the benefit of the Committee, or by 
any applicable law.

     5.  Terms of Grants

     5.1  Grant Agreement.     Each Grant shall be evidenced by a written 
Grant Agreement , which shall be signed by the Participant and by an 
authorized Officer of the Company and which shall refer to such terms and 
conditions as the Committee shall determine, consistent with the Plan.  

     5.2  Issuance of Shares.  Participants shall be issued a certificate for 
fully-paid and nonassessable shares of Common Stock for the number of shares 
covered by the Award, which certificate may contain a legend referring to 
restrictions on vesting and transfer and such other terms and conditions as 
the Committee shall determine, consistent with the Plan.

     5.3  Forfeiture of Unvested Shares.   Shares which have been awarded but 
not yet vested under this Section 5.3 shall be forfeited if the Participant 
ceases to be a Director or Member of the Scientific Advisory Board of the 
Company for any reason, with or without cause, including without limitation, a 
termination by resignation, removal, death, disability, or failure to be 
nominated or reelected by the Company's stockholders, unless provided to the 
contrary in any Grant Agreement approved by the Committee between the 
Participant and the Company, which Agreement shall govern any further vesting 
of shares pursuant to Awards.

     5.4  Fair Market Value.  The Company shall provide to each Participant 
who receives an Award information regarding the Fair Market Value of the 
Company's shares on the date such Award is granted.  Such information shall be 
provided to permit the Participant to determine his or her federal income tax 
liability, if any, for such Award, or to permit the Participant to make the 
election contemplated by Section 78 of the Internal Revenue Code.


     5.5  Transfer Restrictions; Vesting.

          (a)     Unless otherwise approved in writing by the Committee, no 
shares of Common Stock issued pursuant to an Award may be sold, assigned, 
pledged, encumbered, or otherwise transferred until (i) they have vested, and 
(ii) either the Company has made an offering of its shares to the public 
pursuant to a registration statement under the Securities Act or there has 
been a Change of Control of the Company, except as may be provided in Section 
5.5(c) or as may otherwise be provided for in an Grant Agreement which has 
been approved by the Committee.   The Committee, in its absolute discretion, 
may impose such other restrictions on the transferability of the shares 
granted pursuant to an Award as it deems appropriate.  Any such other 
restriction shall be set forth in the respective Grant Agreement and may be 
referred to on the certificates evidencing such shares.  

          (b)     Shares issued to members of the Board of Directors pursuant 
to Awards shall vest 20% at the end of the first year of service after the 
date of the Award and 1/12 of 20% at the end of each month thereafter.  
Subject to the provisions of Sections 5.3, 5.5(c), and 5.5(d), Awards shall 
otherwise become vested at such times and in such installments (which may be 
cumulative) as the Committee shall provide in the terms of each individual 
Grant Agreement; provided, however, that by resolution adopted after an Award 
is granted the Committee may, on such terms and conditions as it may determine 
to be appropriate and subject to Sections 5.3, 5.5(c), and 5.5(d), accelerate 
the time at which such Award or any portion thereof may be vested, or such 
rights may be set forth in an agreement between the Participant and the 
Company which has been approved by the Committee.  Shares issued to members of 
the Scientific Advisory Board shall vest 25% at the end of each three months 
of service after the date of the award.

          (c)     No portion of an Award which is unvested at Termination of 
Relationship shall thereafter become vested; provided, however, that provision 
may be made that such Award shall become vested in the event of a Termination 
of Relationship as may be determined by the Committee, or such rights may be 
set forth in a Grant Agreement between the Participant and the Company which 
has been approved by the Committee.

          (d)     Subject to the provisions of Section 5.5(a), the Committee 
shall provide, in terms of each individual Grant Agreement when such Award 
becomes vested, and (without limiting the generality of the foregoing) the 
Committee may provide in the terms of individual Grant Agreements that 
unvested shares shall be forfeited immediately upon a Termination of 
Relationship; provided, however, that provision may be made that such shares 
shall become vested in the event of a Termination of Relationship because of 
the Participant's retirement, death, disability, or as may otherwise be 
determined by the Committee.

     5.6  No Right to Continued Relationship. Nothing in this Plan or in any 
Grant Agreement issued hereunder shall confer upon any Participant, any right 
to continue his or her association with the Company or shall interfere with or 
restrict in any way the rights of the Company and its stockholders, which are 
hereby expressly reserved, to remove any such person at any time for any 
reason whatsoever, with or without cause.

     
     6.  Additional Provisions. 

     6.1  Nontransferability.  No unvested shares issued pursuant to an Award 
or interest or right therein or part thereof shall be liable for the debts, 
contracts or engagements of the Participant or his successors in interest or 
shall be subject to disposition by transfer, alienation, anticipation, pledge, 
encumbrance, assignment, or any other means whether such disposition be 
voluntary or involuntary or by operation of law by judgment, levy, attachment, 
garnishment or any other legal or equitable proceedings (including bankruptcy 
and divorce proceeding), and any attempted disposition thereof shall be null 
and void and of no effect.

     6.2  Securities Act.  Upon issuance of Common Stock of the Company to the 
Participant, or his heirs, the recipient of that stock shall represent that 
the shares of stock are taken for investment and not resale and shall make 
such other representations as may be necessary to qualify the issuance of the 
shares as exempt from the Securities Act and applicable federal and state 
securities laws and regulations, and shall represent that he or she shall not 
dispose of those shares in violation of the Securities Act or of applicable 
federal and state securities laws and regulations.  The Company reserves the 
right to place a legend on any stock certificate issued pursuant to the Plan 
to assure compliance with this Section and with the vesting and 
transferability requirements of Section 5.  No shares of Common Stock of the 
Company shall be required to be distributed until the Company shall have taken 
such action, if any, as is then required to comply with the provisions of the 
Securities Act or any other then applicable federal or state securities law or 
regulation.

     6.3  Withholding of Tax.  The Company shall have the right to deduct from 
any Award made under the Plan any federal, state or local income or other 
taxes required  by law to be withheld with respect to such Award.  It shall be 
a condition to the obligation of the Company to deliver Common Stock upon an 
Award that the Participant pay to the Company such amount as may be requested 
by the Company for the purpose of satisfying any liability for such 
withholding taxes.  Any grant under this Plan may provide by its terms that 
the Participant may elect, in accordance with any applicable regulations,  to 
pay a portion or all of the amount of such minimum required or additional 
permitted withholding taxes in shares of Common Stock, subject to the timing 
restrictions set forth in Section 6 hereof.  The Participant shall authorize 
the Company to withhold, or shall agree to surrender back to the Company, on 
or about the date such withholding tax liability is determinable, shares of 
Common Stock previously owned by such Participant or a portion of the shares 
that were or otherwise would be distributed to such Participant pursuant to 
such award having a Fair Market Value equal to the amount of such required or 
permitted withholding taxes to be paid in shares.

     6.4  Termination and Amendment of Plan.  The Committee may at any time 
suspend or terminate the Plan, or make such modifications of the Plan as it 
shall deem advisable, provided that the Plan not be changed to increase the 
cost of the Plan to the Company. Notwithstanding anything to the contrary  
contained herein, the Committee shall not amend or modify the Plan more than 
once every six (6) months or in any other manner inconsistent with the 
requirements of Rule 16b-3(c)(2)(ii) except to the extent required by changes 
in the Internal Revenue Code, the Employee Retirement Income Security Act of 
1974, or regulations and rules issued thereunder.  No termination or amendment 
of the Plan may, without the consent of a Participant, adversely affect the 
rights of such Participant notwithstanding anything to the contrary herein.  
No Award may be granted during any period of suspension of the Plan nor after 
termination of the Plan, and in no event may any Award be granted under this 
Plan after August 30, 2004.

     6.5  Duties of the Company.  The Company shall pay all original issue 
taxes with respect to the issuance or delivery of shares pursuant to an Award 
and all other fees and expenses  necessarily incurred by the Company in 
connection therewith.

     6.6  Absence of a Committee.  Should the Board of Directors fail to 
appoint the Committee or should there be no Committee for any other reason, 
then the Plan shall be administered by the Board of Directors.   In the 
absence of a Committee, the Board of Directors (or that portion thereof 
comprised in accordance with this Section 6.6) shall have all the powers of 
the Committee as set forth herein in administration of the Plan.

     7.  General Provisions.

     7.1  No Rights.   Neither the adoption and maintenance of the Plan, the 
granting of Awards pursuant to the Plan, nor issuance of shares pursuant to 
Awards shall be deemed to constitute a contract of employment between the 
Company and any Participant or to be a condition of the employment of any 
person.  The Plan and any Awards granted under the Plan shall not confer upon 
any Participant any right with respect to a  continued relationship with  the 
Company, nor shall they interfere in any way with the right of the Company or 
its shareholders to terminate the relationship of any Participant with the 
Company at any time, and for any reason, with or without cause.

     7.2  Costs of Administration.  The Company shall pay all costs and 
expenses of administering the Plan.

     7.3  Controlling Laws.  The issuance of shares of Common Stock under the 
Plan shall be subject to all applicable laws, rules and regulations, and to 
such approvals by any governmental agencies or national securities exchanges 
as may be required.  The provisions of this Plan shall be interpreted so as to 
comply with the conditions and requirements of the Securities Act, the 
Exchange Act, and rules and regulations issued thereunder, including without 
limitation Rule 16b-3, unless a contrary interpretation of any such provisions 
otherwise required by applicable law.  Except to the extent preempted by 
Federal law, this Plan and all Stock Option Agreements entered into pursuant 
hereto shall be construed and enforced in accordance with, and governed by, 
the laws of the State of Delaware, determined without regard to its conflict 
of laws rules.

     ARTICLE II - GRANT

license, or lease of the Royalty Products, and the practice of Royalty

sublicensees until the reaching of the Royalty Cap.

4.2     Royalty payments shall be paid in United States dollars in 
Gainesville, Florida or at such other place as UFRFI may reasonably designate 
consistent with the laws and regulations controlling in any foreign country.  
If any currency conversion shall be required in connection with the payment of 
royalties hereunder, such conversion shall be made by using the exchange rate 
prevailing at the Chase Manhattan Bank (N.A.) on the last business day of the 
calendar quarterly reporting period to which such royalty payments relate.

4.3     In the event the royalties set forth herein are higher than the

levied by any taxing authority in connection with accrual or payment of any 
royalties payable by Licensee under this Agreement, and Licensee determines in 
good faith that it must pay such taxes, Licensee shall have the right to pay 
such taxes to the local tax authorities on behalf of UFRFI and payment of the 
net amount due after reduction by the amount of such taxes, shall fully 
satisfy Licensee's royalty obligations under this Agreement.  Licensee shall 
provide UFRFI with appropriate receipts or other documentation supporting such 
payment.  Licensee shall inform UFRFI in writing, within thirty (30) days of 
notification that taxes will or have been levied by a taxing authority.

     ARTICLE V - REPORTS AND RECORDS

5.1     Licensee shall keep full, true and accurate books of account 
containing all particulars that may be necessary for the purpose of showing 
the amounts payable to UFRFI hereunder.  Said books of account shall be kept 
at Licensee's principal place of business or the principal place of business 
of the appropriate division of Licensee to which this Agreement relates.  Said 
books and the supporting data shall be open at all reasonable times for five 
(5) years following the end of the calendar year to which they pertain, to the 
inspection of UFRFI or its agents for the purpose of verifying Licensee's 
royalty statement or compliance in other respects with this Agreement.

5.2     Licensee, within forty-five (45) days after December 31 of each 
year, shall deliver to UFRFI true and accurate reports, giving such

Licensee shall so report.


5.4     The royalty payments  set forth in this Agreement shall, if 
overdue, bear interest until payment at the monthly rate of one percent (1%). 
 The payment of such interest shall not foreclose UFRFI from exercising any 
other rights it may have as a consequence of the lateness of any payment.

     ARTICLE VI - PRODUCT LIABILITY

Licensee shall at all times during the term of this Agreement and 
thereafter, indemnify, defend and hold UFRFI and the University of Florida, 
their trustees, officers, employees and affiliates, harmless against all 
claims and expenses, including legal expenses and reasonable attorneys' fees,

this indemnification clause against Licensee, or arising out of the death of 
or injury to any person or persons or out of any damage to property and 
against any other claim, proceeding, demand, expense and liability of any kind 
whatsoever resulting from the production, manufacture, sale, use, lease, 
consumption or advertisement of the Royalty Product(s) and/or Royalty 
Process(es) or arising from any obligation of Licensee hereunder.

     ARTICLE VII - ASSIGNMENT
