ITEM 1. DESCRIPTION OF BUSINESS

GENERAL

      The Company is a development-stage, biopharmaceutical company primarily
focused in the research and development of products and technologies for the
treatment of cancer. The Company has acquired development and marketing rights
to a portfolio of four platform technologies that have been developed over the
past fifteen years, from which seven products and five product candidates have
been derived and additional products may be developed in the future. The
Company's primary objectives are to commence marketing its lead product,
Modrefen, and to continue developing its existing platform technologies and
commercializing products derived from those technologies.

      The Company intends to begin marketing Modrefen (a selective steroid
receptor modulator) on a commercial scale in the United Kingdom before the end
of December 1999. Modrefen is currently licensed in the U.K. for the treatment
of post-menopausal breast cancer and is licensed in the U.S. for the treatment
of certain adrenal disorders. The Company intends to apply before the end of
December 1999 for regulatory approval of Modrefen in the U.S. for treatment of
hormone sensitive cancers. The Company's second lead product, clofarabine (a
purine nucleoside analog), has recently concluded Phase I clinical trials at The
University of Texas M.D. Anderson ("M.D. Anderson"), and the Company anticipates
that it will commence Phase II clinical trials within approximately three
months. Based on third-party studies conducted to date, the Company believes
that clofarabine may be effective in the treatment of leukemia and lymphoma. The
Company intends to request orphan drug designation for clofarabine for leukemia
and lymphoma indications, which will enable the Company to apply for approval of
clofarabine from the U.S. Food and Drug Administration ("FDA") for such
indications upon completion of Phase II clinical trials. In addition, two of the
other products to which the Company has rights are presently being tested in
clinical trials, and an additional eight are in the pre-clinical stage of
development.

      The Company has adopted an aggressive product development program and,
assuming the successful completion of clinical trials, anticipates that by the
end of 2002, five of such products will have received regulatory approval for
certain disease indications in the U.S. or Europe, and seven will be emerging
through the clinical trial process. There can be no assurance, however, that any
of such products will be developed and/or receive applicable regulatory approval
within such time frame.

      The following is a description of the Company's current portfolio of
platform technologies and products.

TECHNOLOGIES

      SELECTIVE STEROID RECEPTOR MODULATION TECHNOLOGY

      The Company has acquired development and marketing rights to a selective
steroid receptor modulation technology. The lead compound of this technology is
Modrefen, which is currently licensed in the U.K. for the treatment of
post-menopausal breast cancer and in several other countries, including the U.S.
and Canada, for the treatment of certain adrenal disorders, such as Cushing's
disease. The Company intends to begin marketing Modrefen on a commercial scale
in the U.K. in the last quarter of 1999 for the treatment of post-menopausal
breast cancer, and at the same time to apply for regulatory approval of Modrefen
in the U.S. for treatment of hormone sensitive cancers. The Company anticipates
that Modrefen will be able to compete with its principal competitor, tamoxifen,
upon receipt of such approval. The Company also intends to pursue opportunities
for Modrefen adrenal disorder products on a smaller scale, principally in the
veterinary market. The Company will also devote its research efforts to discover
new applications for Modrefen and related compounds and to build upon the
selective steroid receptor modulation technology. The Company believes that
Modrefen's dual mode of action not only


                                       2
<PAGE>

makes it a versatile treatment for breast cancer, but may enable it to be
developed for additional disease indications in the future, such as endometrial
and prostate cancers.

      PURINE-BASED NUCLEOSIDE TECHNOLOGY

      The Company has an agreement with the Southern Research Institute ("SRI")
in Birmingham, Alabama to co-develop purine-based nucleoside analogs which,
based on third-party studies conducted to date, may be effective in the
treatment of leukemia and lymphoma. The lead compound of such purine-based
nucleosides is known as clofarabine. Clofarabine has recently successfully
concluded Phase I clinical trials at M.D. Anderson, and the Company anticipates
that it will enter Phase II clinical trials within approximately three months.
Unlike many competing drugs which are administered intravenously, clofarabine
and related products are anticipated to be developed for oral administration,
making it easier for patients to receive them as treatment. The Company intends
to request orphan drug designation for clofarabine for leukemia and lymphoma
indications, which will enable the Company to apply for approval from the FDA
upon completion of Phase II clinical trials. In addition to clofarabine's
effects against leukemia cells, scientists at SRI have shown that it has
anti-tumor activity in vitro against several solid tumors, including cancers of
the colon, kidney and prostate, which distinguishes clofarabine from other drugs
in its class that have shown relatively little activity against solid tumors.
Moreover, other drugs in the purine nucleoside class have been shown to be
effective in the treatment of certain autoimmune diseases. The Company intends
to develop purine nucleoside products for the treatment of solid tumors and
autoimmune diseases simultaneously with the development of clofarabine for the
treatment of hematological cancers. The regulatory approval cycles of those
products, however, are expected to be longer than those for the Company's
hematological cancer products.

      CELL DIFFERENTIATION TECHNOLOGY

      The Company has acquired a right to develop and market three distinct
groups of compounds the Company believes could play an important role in
controlling the rate of growth of cancer cells. The first group of compounds are
synthetic analogs of a drug derived from cottenseed oil. The drug has been
widely tested by clinicians in several countries for a variety of clinical
indications, and data has been published in medical literature. The drug has
shown efficacy against certain cancers by, it is believed, preventing cell
division and promoting cell differentiation. The first compound derived from
this technology, the cancer cytostatic drug, is currently approved for a Phase I
clinical trial at a leading cancer center in the U.K.

      The second group of compounds block enzymes that metabolize RA, a
derivative of vitamin A. RA helps to regulate cell differentiation, a crucial
factor in preventing normal cells from transforming into cancer cells. When the
enzyme that breaks down RA is blocked, there is a buildup of natural RA within
the cell which can prevent or decrease the malignant transformation of cells.
The compounds have been extensively tested in the U.K. at Cardiff University,
and the Company expects to have the lead compounds in Phase I clinical trials
within 18 months.

     The Company has also acquired a license to develop a third group of
compounds that control cell growth and differentiation by effectively blocking
hormone synthesis. A key feature of these compounds is they are non-steroidal
inhibitors of an important enzyme, 17(beta), involved in the production of
androgens and estrogen. Prostate cancer growth is controlled, at least in the
early stages, by androgens and the blockade of these hormones is an essential
part of treating this particular cancer. As with the second group of compounds,
this third group has been extensively tested in the U.K. at Cardiff University,
and the Company also expects to have the lead compounds of this group in Phase I
clinical trials within 18 months.

      GENE THERAPY TECHNOLOGY

      The Company's product portfolio also includes a variety of gene therapy
products which, the Company believes, may offer advancements in the field of
cancer treatment and may have additional applications in certain non-cancer
diseases such as diabetes, cystic fibrosis and other auto-immune disorders.


                                       3
<PAGE>

The company has co-development agreements with the Royal Free and University
College Medical School, London (the "Royal Free Medical School"), one of the
leading medical and scientific institutions in the U.K., pursuant to which the
Company is developing Deoxyribonucleic Acid ("DNA") vector technologies. Based
on pre-clinical research and early Phase I/II clinical trials conducted by a
member of the Company's Scientific Advisory Board, the Company believes these
DNA vector technologies are capable of elevating albumin levels in cancer and
cirrhosis patients with hypo-albuminemia, a serious physiological disorder. The
Company further believes that these technologies have considerable market
potential since low albumin levels are considered to be very dangerous
consequences of many diseases, including cirrhosis and liver cancer. The Company
is also currently working on a gene marker which, based on research work
performed to date by scientists at a London teaching hospital, the Company
believes will enable clinicians to identify the location of DNA transferred
during gene therapy. Although the Company's gene marker product is currently in
the pre-clinical development stage, it is expected to have a relatively short
development cycle and the Company anticipates that, subject to applicable
regulatory approval, the product will be suitable for market distribution by
2002. In addition, the Company is conducting pre-clinical research on a product
that may have the ability to cause tumor regression by enhancing and stimulating
the human body's natural immune cells.

(1)   "Development Phase" refers to the current stage of development of the most
      advanced indication.
      "Research" is a pre-clinical Phase and includes research related to
      specific targets and the identification of lead compounds.
      "Lead compounds" are chemicals that have been identified that meet
      pre-selected criteria in cell culture models for activity and potency
      against specific targets. More extensive evaluation is then undertaken to
      determine if the compound should be selected to enter into pre-clinical
      development. Once a lead compound is selected, chemical modification of
      the compound is then undertaken to create the best drug candidate.
      "Pre-clinical" includes pharmacology and toxicology testing in
      pre-clinical models (in vitro and in vivo), formulation work and
      manufacturing scale-up to gather necessary data to comply with applicable
      regulations prior to commencement of human clinical trials.
      Clinical trials are typically conducted in three sequential phases that
      may overlap. In "Phase I," the initial introduction of the pharmaceutical
      into healthy human volunteers, the emphasis is on testing for safety
      (adverse effects), dosage tolerance, metabolism, distribution, excretion
      and clinical pharmacology. "Phase II" involves studies in a limited
      patient population to determine the efficacy of the pharmaceutical for
      specific targeted indications, to determine dosage tolerance and optimal
      dosage and to identify possible adverse side effects and safety risks.
      Once a compound is found


                                       4
<PAGE>

      to be effective and to have an acceptable safety profile in Phase I and II
      evaluations, "Phase III" trials are undertaken to evaluate clinical
      efficacy further, to further test for safety within an expanded patient
      population at multiple clinical study sites, and to compare the results of
      the trials with those of currently available treatments. Sometimes Phase I
      and II trials or Phase II and III trials are combined. The FDA reviews
      both the clinical plans and the results of the trials and may discontinue
      the trials at any time if there are significant safety issues.

(2)   Modrefen is currently licensed in the U.K. for the treatment of
      post-menopausal breast cancer. It is also presently licensed in several
      other countries, including the U.S. and Canada, for the treatment of
      certain adrenal disorders, such as Cushing's disease. The Company intends
      to file for FDA approval of Modrefen for the treatment of breast cancer in
      the United States in the last quarter of 1999.

CONTRACTUAL ARRANGEMENTS WITH PARTNERS AND LICENSORS

      STEROID RECEPTOR MODULATION TECHNOLOGY SELECTIVE

      In July 1998, the Company entered into an agreement with Stegram
Pharmaceuticals, a U.K. pharmaceutical company ("Stegram"), to co-develop the
selective steroid synthesis-inhibiting and receptor-blocking technology. Under
the terms of the agreement, the Company was granted the exclusive worldwide
license, excluding Japan and South Africa, to make, use and sell products
derived from the technology for a term expiring on the date of expiration of all
current and future patents covered by the agreement (approximately in
2005--subject to earlier termination under certain circumstances), and to
utilize information related to the technology to obtain patent and other
proprietary rights to products developed by the Company and its collaborator
from the technology. In consideration of the licenses granted to the Company,
the Company agreed to pay to its collaborator, among other things, a royalty of
10% of the gross sales revenues of all products, less any discounts or
deductions for value-added taxes incurred and not recovered by the Company.
Beginning July 2001, the Company will be required to pay Stegram a minimum
royalty of $50,000 per year. In addition, the Company has agreed to pay, among
other things, certain costs associated with pre-clinical development and
clinical trials of such products. Under the terms of the agreement, the clinical
trial costs are not to exceed $4,000,000 unless agreed to by both parties.

      PURINE-BASED NUCLEOSIDE TECHNOLOGY

      In August 1998, the Company entered into an agreement with SRI in
Birmingham, Alabama to co-develop the purine-based nucleoside technology. Under
the terms of the agreement, the Company was granted the exclusive worldwide
license, excluding Japan and Southeast Asia, to make, use and sell products
derived from the technology, and to utilize technical information related to the
technology to obtain patent and other proprietary rights to products developed
by the Company and SRI from the technology for a term expiring on the date of
expiration of all current and future patents covered by the agreement. Based on
the patents currently covered by the agreement, the license will expire in the
year 2008, subject to earlier termination under certain circumstances. In
consideration of the liceses granted to the Company, the Company agreed to pay
to SRI, among other things, a royalty of 7% of the gross sales revenues of all
products derived from the technology, less any discounts or deductions for
value-added taxes incurred and not recovered by the Company, plus certain
additional royalty payments in the event the Company achieves certain gross
profit margins. In addition, the Company has agreed to pay, among other things,
certain costs associated with pre-clinical development and clinical trials of
the products developed for hematologic malignancies, including the cost
associated with Phase I clinical trails at M.D. Anderson, which are not to
exceed $1,250,000, unless agreed by both parties.

      Certain patents and other intellectual property rights granted by SRI to
the Company for use in developing clofarabine products are held by the
Sloan-Kettering Institute for Cancer Research ("Sloan-Kettering") in New York
City. In August 1998, SRI entered into an agreement with Sloan-Kettering,
pursuant to which the parties agreed to cooperate in the commercialization of
their respective purine nucleoside technologies. Under the terms of the
agreement, Sloan-Kettering granted to SRI an exclusive, worldwide license to
utilize its technology and agreed to permit SRI to sublicense such technology to
the Company. The parties also agreed that all proceeds received by SRI from the
licensing or other commercial utilization of any portion of Sloan-Kettering's
technology, excluding fees for research and development, will be apportioned 75%
to SRI and 25% to Sloan-Kettering until the termination of SRI's agreement with
the Company.


                                       5
<PAGE>

      The Company has also reached an agreement in principle with M.D. Anderson
pursuant to which M.D. Anderson would be the principal clinical research center
in the United States for all of the Company's products currently in development.
The agreement contemplates the establishment of a trust fund at M.D. Anderson to
receive royalty payments from the direct sale by the Company of its products and
to finance future research at M.D. Anderson. This agreement will become
effective upon the completion of the Company's pending private financing.

      CELL DIFFERENTIATION TECHNOLOGY

      In June 1999, the Company entered into an agreement with the University
College Cardiff Consultants Limited, a company incorporated under the laws of
England and Wales ("Cardiff Consultants"), to develop and commercialize a group
of compounds that are believed to inhibit cancer cell division, and a group of
compounds that inhibit steriodgenesis. Under the agreement the Company acquired
the commercial rights worldwide to develop, manufacture, use, sell or otherwise
deal in these products in connection with cancer therapy in humans and animals
for a term expiring on the date of expiration of all current and future patents
covered by the agreement. In consideration of the licenses granted to the
Company, the Company agreed to pay to Cardiff Consultants, among other things,
an annual royalty of 5% of the gross sales revenues of all products derived from
the technology, less any reasonable discounts and rebates actually given by the
Company for returned products, and a royalty of 35% of the total amounts
received by the Company from any sub-licenses or sales of the technology. In
addition, the Company has agreed to pay, among other things, approximately
$330,000 in connection with a feasibility study of the products to be conducted
by Cardiff University.

      GENE THERAPY TECHNOLOGY

      In March 1999, the Company entered into a co-development and licensing
agreement with the Royal Free and University College Medical School, London
("Royal Free"), a long-established and renowed scientific institution. Royal
Free is the registered owner of patents relating to a DNA vector technology.
Under the terms of the agreement, the Company was granted the exclusive license
to commercially develop the technology for the treatment of liver disorders and
cancer and to market any products derived from the technology in Europe, the
U.S., Canada, Japan and the middle east, for a term expiring on the date of
expiration of all current and future patents covered by the agreement, subject
to earlier termination under certain circumstances. In consideration of the
licenses granted to the Company, the Company agreed to pay to Royal Free, among
other things, a royalty of 6% of the gross sales revenues of all products
derived from the technology, less any normal trade discounts, which shall not be
less than $3,000 in any calendar year. The Company has also agreed to pay Royal
Free a milestone payment of approximately $340,000 in addition to any royalty or
other payments to be made under the agreement upon successful completion of
Phase III clinical trials for the first of the products developed under the
agreement. In addition, the Company has agreed to pay, among other things,
certain costs associated with pre-clinical development and clinical trials of
the products developed from the technology, which are not to exceed $3,000,000.

MANUFACTURING

      The Company does not have and does not intend to establish any internal
product testing, manufacturing or distribution capabilities. The Company's
strategy is to enter into collaborative arrangements with other companies for
the clinical testing, manufacture and distribution of its products. Such
collaborators are generally expected to be responsible for funding or
reimbursing all or a portion of the development costs, including the costs of
clinical testing necessary to obtain regulatory clearances and for
commercial-scale manufacturing, in exchange for exclusive or semi-exclusive
rights to market specific products in particular geographic territories.

      As of the date of this report, however, the Company had only a purchase
order arrangement with a Canadian company for the manufacture and purchase of
clofarabine at the price quotations provided to the Company and had not entered
into any definitive agreements for the manufacture and distribution of any of
its products. The lead compound of the Company's selective steroid receptor
modulation technology, which the Company plans to market as Modrefen, has
historically been manufactured by Sterling-Winthrop Group Limited, from whom
Stegram acquired all right, title and interest in the lead compound. However,
the Company does not have any direct definitive agreement with Sterling-Winthrop
for the continued manufacture of Modrefen. Manufacturers of the Company's
products will be subject to cGMP prescribed by the FDA or other rules and
regulations prescribed by foreign regulatory authorities

SALES AND MARKETING

      The Company has not yet established sales and marketing capabilities. The
Company intends to hire sales and marketing personnel in North America in the
next 12 months upon completion of a private financing and to rely on joint
marketing arrangements with commercial partners for the marketing, sale and
distribution of its products in Europe and other international markets; however,
as of the date of this report, the Company had no such arrangements in place. To
market any of its products directly, the Company will need to develop a
marketing and sales force with technical expertise and distribution capability
or contract with other pharmaceutical and/or health care companies with
distribution systems and direct sales forces. To the extent that the Company
enters into co-promotion or other licensing arrangements, any revenues to be
received by the Company will be dependent on the efforts of third parties.

      COMPETITION

      Competition in the pharmaceutical industry is intense. Potential
competitors in the United States and Europe are numerous and include
pharmaceutical, chemical and biotechnology companies, most of which have
substantially greater capital resources, marketing experience, research and
development staffs and facilities than the Company. The Company seeks to limit
potential sources of competition by developing products that are eligible for
orphan drug designation or other forms of protection, but its competitors may
nevertheless succeed in developing similar technologies and products more
rapidly than the Company.

      The generic drug industry is also intensely competitive and includes large
brand-name and multi-source pharmaceutical companies. Because generic drugs do
not have patent protection or any other market exclusivity, competitors of the
Company may introduce competing generic products, which may be sold at lower
prices or with more aggressive marketing. Conversely, as the Company introduces
branded drugs into its product portfolio, it will face competition from
manufacturers of generic drugs which may claim to offer equivalent therapeutic
benefits at a lower price.

      The pharmaceutical industry is characterized by rapid and significant
technological change. The Company expects that pharmaceutical technology will
continue to develop rapidly, and the Company's future success will depend, in
large part, on its ability to develop and maintain a competitive position.
Technological development by others may result in products developed by the
Company, branded or generic, becoming obsolete before they are marketed or
before the Company recovers a significant portion of the development and
commercialization expenses incurred with respect to such products. In addition,
alternative therapies or new medical treatments could alter existing treatment
regimes, and thereby reduce the need for one or more of the Company's products.

      The Company expects that its proposed products will compete on the basis
of, among other things, safety, efficacy, reliability, price, quality of life
factors (including the frequency and method of drug administration), marketing,
distribution, reimbursement and effectiveness of intellectual property rights.
The Company believes that its competitive success will be based partly on its
ability to attract and retain scientific personnel, establish specialized
research and development capabilities, gain access to manufacturing, marketing
and distribution resources, secure licenses to external technologies and
products, and obtain sufficient development capital. The Company intends to
obtain many of these capabilities from pharmaceutical or biotechnology companies
through collaborative or license arrangements. However, there is intense
competition among early stage biotechnology firms to establish such
arrangements. The Company's development products may not be of suitable
potential market size or provide a compelling return on investment to attract
other firms to commit resources to a collaboration, and even if such
collaborations can be established, the Company may not be able to secure
financial terms that meet the Company's commercial objectives.

RAW MATERIALS

      The Company's raw materials (such as laboratory chemicals) and other
supply items to be used in its research and development processes are available
from many different suppliers and are generally immediately available in
sufficient quantities. The Company does not anticipate any significant problems
in the availability of, or significant price increases for, required raw
materials or other production items in the foreseeable future.

PATENTS AND PROPRIETARY RIGHTS

      The Company's success will depend, in part, on its ability to obtain and
enforce protection for its products under United States and foreign patent laws
and other intellectual property laws, preserve the confidentiality of its trade
secrets and operate without infringing the proprietary rights of third parties.
The Company's policy is to file patent applications in the United States and/or
foreign jurisdictions to protect technology, inventions and improvements to its
inventions that are considered important to the development of its business. The
Company will also rely upon trade secrets, know-how, continuing technological
innovations and licensing opportunities to develop a competitive position.


                                       7
<PAGE>

      The Company, through its current license agreements, has acquired the
right to exploit the technology covered by nine issued patents and six patent
applications, covering the U.S., U.K., Europe, Canada and Japan, as well as
additional intellectual property and know-how that could be the subject of
further patent applications in the future. The Company evaluates the
desirability of seeking patent or other forms of protection for its products in
foreign markets based on the expected costs and relative benefits of attaining
such protection. The Company may not, however, be able to obtain all or any of
the patents for which it applies, and those patents which are issued to the
Company may not afford adequate protection to the Company. Further, issued
patents may be challenged, invalidated, infringed or circumvented and rights
granted thereunder may not provide competitive advantages to the Company.
Furthermore, parties not affiliated with the Company may have obtained or may in
the future obtain United States or foreign patents or may now possess or in the
future may possess proprietary rights relating to the Company's products that
will adversely affect the development or commercialization of the Company's
products or result in the Company's planned activities infringing patents owned
by others.

      The Company could incur substantial costs in defending itself in
infringement suits brought against it or any of its licensors or in asserting
any infringement claims that the Company may have against others. The Company
could also incur substantial costs in connection with any suits relating to
matters for which the Company has agreed to indemnify its licensors or
distributors. An adverse outcome in any such litigation could have a material
adverse effect on the Company's business and prospects. In addition, the Company
could be required to obtain licenses under patents or other proprietary rights
of third parties and, if the Company does not obtain any such required licenses,
it could be prevented from, or encounter delays in, developing, manufacturing or
marketing one or more of its products.

      The Company also relies upon trade secret protection for its confidential
and proprietary information. Third parties may independently develop
substantially equivalent proprietary information and techniques or otherwise
gain access to the Company's trade secrets or disclose such technology, in any
one or more of such events the Company might not be able to protect its trade
secrets.

      The Company plans to implement a policy to require its employees,
consultants, members of the Scientific Advisory Board and parties to
collaborative agreements to execute confidentiality agreements upon the
commencement of employment or consulting relationships or a collaboration with
the Company. These agreements provide that all confidential information
developed or made known during the course of the relationship with the Company
is to be kept confidential and not disclosed to third parties except in specific
circumstances. In the case of employees, the agreements provide that all
inventions resulting from work performed for the Company, utilizing property of
the Company or relating to the Company's business and conceived or completed by
the individual during employment shall be the exclusive property of the Company
to the extent permitted by applicable law. These agreements may not, however,
provide meaningful protection of the Company's trade secrets or adequate
remedies in the event of unauthorized use or disclosure of such information.

GOVERNMENT REGULATION

      Virtually all aspects of the Company's business are regulated by federal
and state statutes and governmental agencies in the United States and other
countries. The development, testing, manufacturing, processing, quality, safety,
efficacy, packaging, labeling, record-keeping, distribution, storage and
advertising of pharmaceutical products, and disposal of waste products arising
from such activities, are subject to regulation by one or more federal agencies,
including the FDA, the Department of Environmental Protection ("DEA"), the
Federal Trade Commission ("FTC"), the consumer Product Safety Commission
("CPSC"), the Occupational Safety and Health Administration ("OSHA") and the
Environmental Protection Agency ("EPA"). These activities are also regulated by
corresponding state and local agencies and equivalent foreign authorities.

      All pharmaceutical manufacturers in the United States are subject to
regulation by the FDA under the authority of the Food, Drug and Cosmetics Act
(the "FDC Act"). Under the FDC Act, the federal government has extensive
administrative and judicial enforcement powers over the activities of
pharmaceutical manufacturers to ensure compliance with FDA regulations. Those
powers include, but are not limited to, the authority to initiate


                                       8
<PAGE>

court action to seize unapproved or non-complying products, to enjoin
non-complying activities, to halt manufacturing operations that are not in
compliance with cGMP, to recall products which present a health risk, and to
seek civil monetary and criminal penalties. Other enforcement activities include
refusal to approve product applications or the withdrawal of previously approved
applications. In addition, product recalls may be issued at the discretion of
the Company, the FDA or other domestic and foreign government agencies having
regulatory authority for pharmaceutical product sales. Recalls may occur due to
disputed labeling claims, manufacturing issues, quality defects or other
reasons. The pharmaceutical products developed by the Company may be subject to
any one or more of such recalls in the future.

      The Company has a variety of products under development, including line
extensions of existing products, reformulations of existing products and new
products. All "new drugs" must be the subject of an FDA-approved new drug
application ("NDA") before they may be marketed in the United States. All
generic equivalents of previously approved drugs or new dosage forms of existing
drugs must be the subject of an FDA-approved abbreviated new drug application
("ANDA") before they may by marketed in the United States. In both cases, the
FDA has the authority to determine what testing procedures are appropriate for a
particular product and, in some instances, has not published or otherwise
identified guidelines as to the appropriate procedures. The FDA has the
authority to withdraw existing NDA and ANDA approvals and to review the
regulatory status of products marketed under the enforcement policy. The FDA may
require an approved NDA or ANDA for any drug product marketed under the
enforcement policy if new information reveals questions about the drug's safety
or effectiveness. All drugs must be manufactured in conformity with cGMP and
drugs subject to an approved NDA or ANDA must be manufactured, processed,
packaged, held and labeled in accordance with information contained in the NDA
or ANDA.

      Even if required FDA approval has been obtained with respect to a product,
foreign regulatory approval of a product must also be obtained prior to
marketing the product internationally. Foreign approval procedures vary from
country to country and the time required for approval may delay or prevent
marketing. In certain instances, the Company or its collaborative partners may
seek approval to market and sell certain of its products outside of the United
States before submitting an application for approval to the FDA. The regulatory
procedures for approval of new pharmaceutical products vary significantly among
foreign countries. The clinical testing requirements and the time required to
obtain foreign regulatory approvals may differ from that required for FDA
approval. Although there is now a centralized European Union ("EU") approval
mechanism for new pharmaceutical products in place, each EU country may
nonetheless impose its own procedures and requirements, many of which are
time-consuming and expensive, and some EU countries require price approval as
part of the regulatory process. Thus, there can be substantial delays in
obtaining required approval from both the FDA and foreign regulatory authorities
after all relevant applications are filed.

      ANDA PROCESS. FDA approval is required before a generic equivalent to a
previously approved brand drug or new dosage form of an existing brand drug can
be marketed. Approval to market such products in the United States may be
obtained by submitting an ANDA to the FDA. Among the requirements for drug
approval by the FDA is that the manufacturing procedures and operations of
companies that manufacture products for the Company conform to cGMPs. If the FDA
believes a company is not in compliance with cGMPs, certain sanctions are
imposed upon that company including: (i) withholding from the company new drug
approvals as well as approvals for supplemental changes to existing
applications; (ii) preventing the company from receiving the necessary export
licenses to export its products; and (iii) classifying the company as an
"unacceptable supplier" and thereby disqualifying the company from selling
products to federal agencies. Moreover, in May 1992, the Generic Drug
Enforcement Act (the "Generic Act") was enacted. The Generic Act allows the FDA
to impose debarment and other penalties on individuals and companies that commit
certain illegal acts relating to the generic drug approval process. In some
situations, the Generic Act requires the FDA to debar (i.e., not accept or
review ANDAs for a period of time) a company or an individual that has committed
certain violations. It also provides for temporary denial of approval of
applications during the investigation of certain violations that could lead to
debarment and also, in more limited circumstances, provides for the suspension
of the marketing of approved drugs by the affected company. Lastly, the Generic
Act allows for civil penalties and the withdrawal of previously approved
applications. Neither the Company nor any of its employees has ever been subject
to debarment.


                                       9
<PAGE>

      NDA PROCESS. FDA approval is required before any new drug can be marketed.
An NDA is a filing submitted to the FDA to obtain approval of a drug not
eligible for an ANDA and must contain complete pre-clinical and clinical safety
and efficacy data or a right of reference to such data. Clinical trials are
typically conducted in three sequential phases. In Phase I, the product is
tested for safety, adverse effects, dosage, tolerance absorption, metabolism,
excretion and other elements of clinical pharmacology, frequently through
introduction of the compound into healthy human beings. Phase II typically
involves studies in a small sample of the intended patient population to assess
the efficacy of the compound for a specified indication, to determine dose
tolerance and the optimal dose range and to gather additional information
relating to safety and potential adverse effects. Phase III trials are
undertaken to further evaluate clinical safety and efficacy in an expanded
patient population at typically dispersed study sites, in order to determine the
overall risk-benefit ratio of the compound, and to provide an adequate basis for
product labeling.

      Data from pre-clinical testing and clinical trials are submitted to the
FDA as an NDA for marketing approval and to other health authorities as a
marketing authorization application. The approval process is affected by a
number of factors, and the FDA or other health authorities may deny an NDA or
marketing authorization application if the regulatory criteria are not
satisfied. Even after initial FDA or other health authority approval has been
obtained, further studies, including Phase IV post-marketing studies, may be
required to provide additional data on safety. Additional studies generally also
are required to gain approval for the use of a product as a treatment for
clinical indications other than those for which the product was initially
tested. Also, the FDA or other regulatory authorities require post-marketing
reporting to monitor the adverse effects of the drug. Results of post-marketing
programs may limit or expand the further marketing of the products. Further, if
there are any modifications to the drug, including changes in indication,
manufacturing process or labeling or a change in the manufacturing facility, an
application seeking approval of such changes must be submitted to the FDA or
other regulatory authority. The Company has not experienced sanctions or fines
for non-compliance with the foregoing regulations.

      FOREIGN REGULATORY PROCESS. To market drugs in non-U.S. jurisdictions, the
Company must also receive authorization from the respective regulatory
authorities in those jurisdictions. The requirements governing the conduct of
clinical trials, applications for marketing authorization, pricing and
reimbursement vary widely from jurisdiction to jurisdiction. In the EU,
pharmaceutical legislation requires that a Marketing Authorization Application
("MAA") for a drug produced through the use of biotechnology be submitted for
review in accordance with a centralized procedure administered by the European
Medicines Evaluation Agency (the "EMEA"), headquartered in London. If approved
by the EMEA, an MAA is recommended for acceptance by the EU. Following approval
of an MAA for a drug, the sponsoring company is required to negotiate with the
regulatory agency in each member country to establish reimbursement levels and
the maximum price at which the drug may be marketed in that country. These
reimbursement levels and maximum prices vary from country to country for the
same pharmaceutical. The regulatory requirements applicable to any product may
be modified, perhaps extensively, in the future. The Company cannot determine
what effect changes in regulations or statutes or legal interpretations, when
and if promulgated or enacted, may have on its business in the future. Moreover,
regulatory approval for marketing a proposed pharmaceutical product in any
particular jurisdiction will not necessarily result in similar approval in other
jurisdictions.

      ORPHAN DRUG DESIGNATION. Under the Orphan Drug Act, the FDA may grant
orphan drug designation to drugs intended to treat a "rare disease or
condition," which generally is a disease or condition that affects populations
of fewer than 200,000 people in the United States. Orphan drug designation must
be requested before submitting an NDA, and after the FDA grants orphan drug
designation, the generic identity of the therapeutic agent and its potential
orphan use are publicized by the FDA. Under current law, orphan drug status is
conferred upon the first company to receive FDA approval to market the
designated drug for the designated indication, which also grants United States
marketing exclusivity for a period of seven years following approval of the NDA,
subject to certain limitations. Orphan drug designation does not convey any
advantage in, or shorten the duration of, the FDA regulatory approval process.
Moreover, although obtaining FDA approval to market a product with orphan drug
status can be advantageous, the scope of protection and/or the level of
marketing exclusivity that is currently afforded by orphan drug status and
marketing approval may be diminished or eliminated in the future. Moreover, NDA
approval of a drug with an orphan drug designation does not prevent the FDA from
approving the same drug for a different indication, or a molecular variation of
the same drug for the same indication. Because doctors are not


                                       10
<PAGE>

restricted by the FDA from prescribing an approved drug for uses not approved by
the FDA, it is also possible that another company's drug could be prescribed for
indications for which a product developed by the Company has received orphan
drug designation and NDA approval.

PRODUCT LIABILITY AND INSURANCE

      The Company faces exposure to product liability claims in the event that
the use of its technologies or products or those it licenses from third parties
is alleged to have resulted in adverse effects in users thereof. Receipt of
regulatory approval for commercial sale of such products does not mitigate such
product liability risks. While the Company has filed applications with a
reputable insurance company for the purpose of obtaining what it believes to be
adequate product liability insurance, as of the date of this report the Company
has not obtained any such insurance. There can be no assurance that the
precautions taken by the Company will be sufficient to avoid significant product
liability exposure. in addition, future product labeling may include disclosure
of additional adverse effects, precautions and contradictions, which may
adversely impact sales of such products.

EMPLOYEES

      As of September 15, 1999, the Company had four employees, consisting of
one sales and marketing executive, two research and development executives and
one financial executive. None of the Company's employees is represented by a
labor union and the Company believes its relations with its employees are good.

CORPORATE HISTORY

      The Company was incorporated as Express Finance Inc. under the laws of the
State of Delaware on August 16, 1996 and changed its name to Ascot Group Inc. on
August 26, 1998. Although the Company was initially formed to act as the U.S.
holding company for Mayhem Ltd., a U.K. corporation, it did not engage in any
active trade or business throughout the period from its inception to December
1998.

      In December 1998, the Company entered into an agreement to purchase all of
the issued and outstanding shares of capital stock of Bioenvision Inc., a
development-stage company incorporated in November 1996 under the laws of the
State of Delaware ("Old Bioenvision"). Old Bioenvision primarily engaged in the
research and development of products and technologies for the treatment of
cancer and had acquired development and marketing rights to a portfolio of
platform technologies that had been developed over the past fifteen years and
from which various products were being derived. Old Bioenvision had two
wholly-owned subsidiaries, Biotechnology & Healthcare Ventures Ltd. ("BHV"), a
corporation organized under the laws of the Republic of Ireland, and Eurobiotech
Group, Inc., a company incorporated under the laws of the State of Delaware.
BHV, in turn, owned all of the outstanding shares of capital stock of each of
Bioheal Ltd., a corporation organized under the laws of the Republic of Ireland,
and Biomed (UK) Ltd., a corporation organized under the laws of the United
Kingdom.

      Pursuant to the Company's agreement to acquire Old Bioenvision, the
Company effected a 1-for-15 reverse stock split of its then outstanding shares
of Common Stock and issued 7,013,897 post-reverse split shares of Common Stock
to the former stockholders of Old Bioenvision in exchange for all of the issued
and outstanding shares of capital stock of Old Bioenvision. Consequently, upon
consummation of the transaction in January 1999, the former stockholders of Old
Bioenvision became the controlling stockholders of the Company, Old Bioenvision
became a wholly-owned subsidiary of the Company and changed its name to Bionco
Marketing Inc., and the Company changed its name from Ascot Group Inc. to
Bioenvision Inc.

ITEM 2. DESCRIPTION OF PROPERTY

FACILITIES

      As of the date of this report the Company does not have any interest in
real property. The Company currently uses the offices of its financial advisor
at One Rockefeller Plaza, Suite 1600, New York, New York for its principal
executive offices at no cost. This office space is used by management and
administration. To date, most of the Company's drug development programs have
been conducted at scientific institutions around the world. It is the Company's
policy to continue development at leading scientific institutions in the United
States and Europe. The Company intends to lease facilities that will serve as
its corporate headquarters in the United States upon completion of a private
financing. These facilities will be the center for all of the Company's
administrative and marketing functions in the United States. The Company does
not plan to conduct laboratory research in such facilities in the near future,
but, rather, will conduct research through collaborative arrangements with SRI
and M.D. Anderson.

INVESTMENT POLICIES

      The Company does not currently have any investments in real estate or
interests in real estate, nor in real estate mortgages nor in the securities of
or interests in persons primarily engaged in real estate. The Company generally
acquires its assets for the purpose of ultimately producing sales revenues from
the exploitation of such assets in the development of the Company's
biopharmaceutical business. The Company does not currently have any surplus cash
to invest, but the Company intends to invest any surplus cash it may have on
hand in the future in interest-bearing deposit accounts, short-term certificates
of deposit and governmental debt instruments.

ITEM 3. LEGAL PROCEEDINGS

      There are no material legal proceedings pending to which the Company or
any of its property is currently subject.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

      No matters were submitted to a vote of security holders during the fourth

      *In accordance with the terms of the Acquisition Agreement between Old
Bioenvision and the Company dated December 21, 1998 (the "Acquisition
Agreement"), the Company effected a 1-for-15 reverse stock split, reducing its
issued and outstanding shares of Common Stock from 3,450,000 to 230,000,
immediately prior to issuing 7,013,897 shares of post 1-for-15 reverse stock
split Common Stock at the closing of the Acquisition on January 5, 1999.

      HOLDERS. On September 15, 1999 the Company had 261 stockholders of record.

RECENT SALES OF UNREGISTERED SECURITIES

      In September 1998, the Company granted options to Glen Investments
Limited, a Jersey (Channel Islands) corporation ("Glen Investments") wholly
owned by Kevin R. Leech, a U.K. citizen, to purchase up to 500,000 shares of
Common Stock at an exercise price of $1.00 per share in exchange for the
agreement by Glen to loan funds to the Company on an as-needed basis based upon
previously agreed budgets. Such optioins are presently exercisable. The issuance
of such options was exempt from registration under Regulation S promulgated
under the Securities Act based upon representations and warranties made by Glen
as to the status of Glen as an offshore buyer and Glen's covenants and
agreements not to offer or sell the subject shares within the United States at
any time such as would disqualify the private placement from the exemption under
Regulation S.

      Effective as of January 5, 1999, pursuant to the Acquisition Agreement the
Company effected a 1-for-15 reverse stock split and thereafter issued 7,013,897
post-reverse split shares of Common Stock to the stockholders of Old Bioenvision
in exchange for 7,013,897 shares of common stock of Old Bioenvision, comprising
all of the issued and outstanding shares of capital stock of Old Bioenvision, in
a tax-free exchange. The issuance of such shares was exempt from registration
under Regulation S promulgated under the Securities Act based upon
representations and warranties made by the purchasers thereof who were citizens
of the United Kingdom as to their status as offshore buyers and their covenants
not to offer or sell the subject shares within the United States at any time
such as would disqualify the private placement from the exemption under
Regulation S, and under Section 4(2) of the Securities Act with respect to those
investors who were United States citizens, based upon their representations that
they were accredited investors as defined under the Commission's Rule 501(a).

      In April 1999 the Company issued an aggregate of 4,000 shares of Common
Stock to Inpharmation Ltd. in partial consideration for consulting services
rendered to the Company. The issuance of such shares was exempt from
registration under Regulation S promulgated under the Securities Act based upon
representations and warranties made by the purchaser as to its status as an
offshore buyer and its covenant not to offer or sell the subject shares within
the United States at any time such as would disqualify the private placement
from the exemption under Regulation S.

      In April 1999 the Company issued 1,250 shares of Common Stock to
Christopher P. Oliver. The issuance of such shares was exempt from registration
under Regulation S promulgated under the Securities Act based upon
representations and warranties made by the purchaser as to its status as an
offshore buyer and its covenant not to offer or sell the subject shares within
the United States at any time such as would disqualify the private placement
from the exemption under Regulation S.

DIVIDEND POLICY

      The Company has never declared or paid cash dividends on its capital
stock, and the Company's Board of Directors does not intend to declare or pay
any dividends on the Common Stock in the foreseeable future. Earnings of the
Company, if any, are expected to be retained for use in expanding the Company's
business. The declaration and payment in the future of any cash or stock
dividends on the Common Stock will be at the discretion of the Board of
Directors of the Company and will depend upon a variety of factors, including
the ability of the Company to service its outstanding indebtedness and to pay
its dividend obligations on securities ranking senior to the Common Stock, the
Company's future earnings, if any, capital requirements, financial condition and
such other factors as the Company's Board of Directors may consider to be
relevant from time to time.

ITEM 6. MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATIONS

OVERVIEW

      The Company was organized in August 1996 for the purpose of acting as a
publicly traded holding company for Mayhem Ltd., a United Kingdom corporation.
That purpose was never realized and prior to the change in control of the
Company in January 1999, the Company did not engage in any active trade or
business. The Company is considered a development-stage company for accounting
purposes because it has not generated any material revenues to date.
Accordingly, the Company has no relevant operating history upon which an
evaluation of the Company's performance and prospects can be made. Moreover, the
Company is still subject to all of the business risks associated with a new
enterprise, including, but not limited to, risks of unforeseen capital
requirements, lack of fully developed products, failure of market acceptance,
failure to establish business relationships, reliance on outside contractors for
the manufacture and distribution of proposed products, and competitive
disadvantages as against larger and more established companies. The likelihood
of the success of the Company must be considered in light of the development
cycles of new pharmaceutical products and technologies and the competitive and
regulatory environment in which the Company operates.

      The company is an international biopharmaceutical company primarily
engaged in the research and development of products and technologies for the
treatment of cancer. During its development stage the Company has been primarily
engaged in organizational activities, including developing a strategic operating
plan, entering into various collaborative agreements for the development of
products and technologies, hiring personnel and developing and testing its
products. The Company plans to begin marketing its lead product, Modrefen, on a
commercial scale in the U.K. prior to the end of December of 1999. The Company
has assembled the core of its management team, which includes a Chairman of the
Board and Chief Executive Officer, Senior Vice President and Chief Medical
Officer.

PLAN OF OPERATIONS

      The Company has acquired development and marketing rights to a portfolio
of four platform technologies developed over the past fifteen years, from which
seven products and five product candidates have been derived and additional
products may be developed in the future. Although the Company intends to
commence marketing its lead product, Modrefen, and to continue developing its
existing platform technologies and commercializing products derived from such
technologies, a key element of the Company's business strategy is to continue to
acquire, in-license and develop new technologies and products that the Company
believes offer unique market opportunities and/or complement the Company's
existing product lines. Once a product or technology has been launched into the


                                       14
<PAGE>

market for a particular disease indication, the Company plans to work with
numerous collaborators, both pharmaceutical and clinical, in the oncology
community to extend the labeling of the drug to other indications. In order to
market its products effectively, the Company intends to develop marketing
alliances with strategic partners and may co-promote and/or co-market in certain
territories.

LIQUIDITY AND CAPITAL RESOURCES

      From the period of its inception through December 1998, the Company did
not engage in any active trade or business. In January 1999, the Company
consummated a merger with Old Bioenvision by effecting a 1-for-15 reverse stock
split of its then outstanding shares of Common Stock and thereafter issuing
7,013,897 post-reverse split shares of Common Stock to the former stockholders
of Old Bioenvision in exchange for all of the issued and outstanding shares of
capital stock of Old Bioenvision. Consequently, upon consummation of the merger,
the former stockholders of Old Bioenvision became the controlling stockholders
of the Company, Old Bioenvision became a wholly-owned subsidiary of the Company
and changed its name to Bionco Marketing Inc., and the Company changed its name
from Ascot Group Inc. to Bioenvision Inc.

      To date, the Company has incurred significant net losses, including net
losses of $765,154 for the fiscal year ended June 30, 1998 and net losses of
$495,193 for the fiscal year ended June 30, 1999. The Company had an accumulated
deficit of $837,193 at June 30, 1998 and $1,332,386 at June 30, 1999 and, since
that date, the Company has continued to incur significant and increasing losses.
The Company anticipates that it may continue to incur significant operating
losses for the foreseeable future. There can be no assurance as to whether or
when the Company will generate material revenues or achieve profitable
operations. The Company's independent public accountants have included an
explanatory paragraph in their report on the Company's financial statements,
stating that certain factors raise substantial doubt about the Company's ability
to continue as a going concern.

In the year ended June 30, 1999 administrative expenses totaled pound 379,279
compared to pound 689,499 for the year ended June 30, 1998. The reduction in
expenses is a result of the Company realizing cost savings following
reorganization the year.

Research and development expenses were $100,000 in the year ended June 30, 1999
compared to ---[?]--- for the year ended June 30, 1998. The increase in research
and development costs is a result of the Company increasing it's research
activities during 1999 in-line with the development of its products.

      Based on its current operating plan, the Company believes that the
estimated minimum amount of net proceeds from its anticipated private financing
will be sufficient to meet its cash, operational and liquidity requirements for
at least 12 months following the completion of such financing, and that the
estimated maximum net proceeds from such private financing will be sufficient to
meet its cash, operational and liquidity requirements for at least 18 months
following the completion thereof. The Company may, however, require additional
financing within this time frame due to unanticipated changes in economic
conditions or other unforeseen circumstances. In the event the Company's plans
change or its assumptions change or prove to be inaccurate, the Company could be
required to seek additional financing sooner than currently anticipated. The
Company currently has an agreement with Glen Investments Limited, a Jersey
(Channel Islands) company wholly owned by Kevin R. Leech (a private investor who
is also the sole owner of Phoenix Ventures Limited, the holder of approximately
19% of the outstanding shares of Common Stock of the Company), whereby Glen
Investments has agreed to loan funds to the Company on an as-needed basis based
upon previously agreed budgets. A facility of pound is currently available to
the Company based an budgets that assume the above private plaement is
successful. Glen Investments Ltd. has agreed to satisfactory review of revised
budgets. Any additional financing may not, however, be available to the Company
when needed on commercially reasonable terms, or at all. If the Company is
unable to obtain such additional financing, the Company's operations will, in
all likelihood, cease.

YEAR 2000 ISSUE

      The year 2000 issue refers to the potential failures that computer systems
may incur as a result of the date change from 1999 to 2000. Many existing
computer programs use only two digits to identify a change of the century. As a
result, computer systems using these programs may be unable to properly
recognize date-sensitive data resulting in the creation of erroneous information
or system failure.

      Although the Company does not currently have any computer or other systems
that may be susceptible to the year 2000 issue, the Company's products
are mostly being developed in various research institutions which may have
systems that are not year 2000 compliant. A possible worst case year 2000
scenario for the Company would be if the research institutions' systems failed.
If their networks fail for an extended period of time due to the


                                       15
<PAGE>

year 2000 issue, the Company may no longer be able to continue developing and
testing its products. In the event such systems are not year 2000 compliant on a
timely basis, the Company will seek to develop and test its products at
institutions whose systems are year 2000 compliant. The Company has no assurance
that this can be accomplished in a timely or cost effective manner.

      The Company is currently evaluating such year 2000 issues and their
potential impact on its business, and has commenced inquiries to determine the
status of preparations by the research institutions where the Company's products
are tested to become year 2000 compliant. Although the Company's management
expects to incur cots in correcting any year 2000 issues arising as a result of
such research institutions' handling of their own year 2000 issues, management
cannot currently estimate those costs. All such costs will be expensed as
incurred. The Company does not expect that the cost of addressing any year 2000
issue will be a material event or uncertainty that would cause its reported
financial information not to be necessarily indicative of future operating
results or future financial condition, or that the costs or consequences of
incomplete or untimely resolution of any year 2000 issue represent a known
material event or uncertainty that is reasonably likely to affect its future
financial results, or cause its reported financial information not to be
necessarily indicative of future operating results or future financial
condition. However, if the Company encounters any unanticipated delays in, or
costs associated with, the resolution of any year 2000 issue, the Company's
business, financial condition and results of operations could be materially
adversely affected.

ITEM 8. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND
        FINANCIAL DISCLOSURE.

      On September 30, 1999 the Company and its former auditors, Graf Repetti &
Co., LLP ("Graf Repetti") agreed to terminate their relationship as of such
date. As of October 1, 1999, the Company retained Ernst & Young as its
independent public accountants. The decision to terminate its relationship with
Graf Repettis was recommended and approved by the Board of Directors and was
based upon the Company's need to have auditors with international auditing
capability.

      During the period from inception on August 16, 1996 through and including
June 30, 1998, and for the interim period from July 1, 1998 through March 31,
1999, Graf Repetti's reports on the Company's financial statements neither
contained any adverse opinions or disclaimers of opinions nor were qualified or
modified as to uncertainty, except that Graf Repetti's auditors' report on the
Company's consolidated financial statements for the fiscal period ended June 30,
1998 expressed substantial doubt about the Company's ability to continue as a
going concern owing to the Company's losses from operations and net capital
deficiency.

      During the fiscal period commencing with inception on August 16, 1996 and
ended June 30, 1998, and for the interim period from July 1, 1998 through March
31, 1999, there were no disagreements with Graf Repetti on any matter of
accounting principles or practices, financial statement disclosure or auditing
scope or procedure, which disagreements, if not resolved to the satisfaction of
Graf Repetti, would have caused it to make reference to the subject matter of
the disagreements in connection with its reports.

the terms of the agreement, Bioheal was granted the exclusive license to make,
use and sell products derived from technology, and to utilize technical
information related to the technology to obtain patent and other proprietary
rights to products developed by Bioheal and its collaborators from the
technology for a term expiring on the date of expiration of all current and
future patents covered by the agreement, subject to earlier termination under
certain circumstances. In consideration of the licenses granted to Bioheal,
Bioheal agreed to pay to Dr. Wood, among other things, a royalty of 10% of the
gross sales revenues of all products, less and discounts or deductions for
value-added taxes. In addition, Bioheal has agreed to pay, among other things,
certain costs associated with pre-clinical development and clinical trials of
such products. Under the terms of the agreement, the pre-clinical costs are not
to exceed $1,500,000, and the clinical trial costs are not to exceed $4,000,000,
unless agreed by both parties.

Leech is a private investor who is also the sole owner of Phoenix Ventures
Limited, a Guernsey (Channel Islands) corporation and the holder of

exercise price of $1.00 per share, all of which options are currently
exercisable. As of the date of this Memorandum, Glen Investments had loaned the
Company a total of $280,000 (approximately $170,000) out of a total facility
currently of pound 1 million (approximately $1.65 million).

REPORT OF INDEPENDENT AUDITORS

The Board of Directors and Shareholders
Bioenvision, Inc. (formerlly Ascot Group, Inc.) (a development stage company)

We have audited the accompanying consolidated balance sheets of Bioenvision,
Inc. (formerlly Ascot Group, Inc.) (a development stage company) as of June 30,
1999, and the related consolidated statements of operations, stockholders'
equity, and cash flows for each of the two years in the period ended June 31,
1999 and for the period from August 16, 1996 (inception) through June 30, 1999.
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 auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Bioenvision, Inc.
(formerlly Ascot Group, Inc.) at June 30, 1999, and the consolidated results of
its operations and its consolidated cash flows for each of the two years in the
period ended June 30, 1999 and for the period from August 16, 1996 (inception)
through June 30, 1999, in conformity with accounting principles generally
accepted in the United States.

As discussed in Note 1 to the consolidated Financial Statements, the Company has
incurred losses from operations and is not currently generating cash from
operations. This factor raises substantial doubt about the Company's ability to
continue as a going concern. Management's plans as to this matter are also
described in Note 1. The financial statements do not include any adjustments
that might result from the outcome of this uncertainty.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANISATION AND SIGNIFICANT ACCOUNTING POLICES.

DESCRIPTION OF BUSINESS

The Company is a development stage, biopharmaceutical company primarily focused
in the research and development of products and technologies for the treatment
of cancer. The Company has acquired development and marketing rights to a
portfolio of four platform technologies.

The Company was incorporated as Express Finance, Inc. under the laws of the
State of Delaware on August 16, 1996 and changed its name to Ascot Group, Inc.
on August 26, 1998 and further to Bioenvision, Inc. in December 1998.

BASIS OF PRESENTATION

In January 1999 the Company merged with Bioenvision, Inc, ('Old Bioenvision') a
development stage Company primarily engaged in the research and development of
products and technologies for the treatment of cancer. The transaction was
accounted for as a reorganisation of companies under common control in a manner
similar to a pooling of interests as they had a common majority shareholder. All
prior period amounts have been restated to include the financial results of Old
Bioenvision.

In September 1998, Old Bioenvision merged with Eurobiotech Group, Inc., a
development stage company involved in the research and development of products
and technologies for the treatment of cancer. The transaction was accounted for
as a combination of a reorganisation of companies under common control in a
manner similar to a pooling as they had a common majority shareholder, and the
purchase of a minority interest. All prior year amounts have been restated.

In July 1998, Old Bioenvision merged with Biotechnology & Healthcare Ventures
Limited ('BHV'), a development stage company involved in the research and
development of products and technologies for the treatment of cancer. The
transaction was accounted for as a reorganisation of companies under common
control in a manner similar to a pooling of interests as they had a common
majority shareholder. All prior period amounts have been restated to reflect the
financial results of BHV.

BHV acquired Bioheal Limited and Biomed UK Limited in May 1998, both of which
are development stage companies involved in the research and development of
products and technologies for the treatment of cancer. Both of the transactions
were accounted for as purchases and the results of Biomed UK Limited and Bioheal
Limited have been included in the financial statements of BHV from the date of
acquisition.

Where mergers have been accounted for as reorganisations under common control in
a manner similar to a pooling of interests, no fair values have been attributed
to any tangible or intangible assets, including technology rights.

The financial statements expressed in pounds sterling as of June 30, 1999 and
for the year then ended and the period August 16, 1996 (inception) to June 30,
1999 were translated in to US dollars, solely for the convenience of the reader,
at the prevailing exchange rate of (pound)1 = $1.5765. These translations should
not be construed as representations that the pound sterling amounts actually
represent US dollar amounts or that they could be converted into US dollars at
the rate indicated or at any other rate.

The Company has incurred significant losses from operations and is not currently
generating cash from operations. The Company anticipates that it may continue to
incur significant operating losses for the foreseeable future. Operations to
date have been funded principally by equity capital and borrowings. The Company
intends to continue to fund its development expenses through additional capital
raising activities, including one or more offerings of equity and/or debt
through private placements and/or public offerings.

In particular, stockholders have approved the offering, through a private
placement, of 1,000,000 shares of preferred stock in the Company. Based on its
current operating plan, the Company believes  that the estimated amount of net
proceeds will be sufficient to meet its cash, operational and liquidity
requirements for at least the 12 months following the closing of such a private
placement.

In addition, the Company has entered into an agreement with Glen Investments
Ltd., a related party (see note 8) whereby Glen Investments Ltd. has agreed to
loan funds to the Company on an as-needed basis based upon previously agreed
budgets. A facility of pound 1 million is currently available to the Company
based on budgets that assume the above private placement is successful. If the
private placement proves to be unsuccessful, Glen Investments Ltd. has agreed to
support the Company for the forthcoming year, subject to satisfactory review of
revised budgets.

The Company's ability to continue to develop its infrastructure depends upon its
ability to raise equity capital through the approved private placement, the
continuing availability of funding from Glen Investments and upon its ability to
raise other additional capital. The financial statements do not include any
adjustments that may result from this uncertainty.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

PRINCIPLES OF CONSOLIDATION

The accompanying consolidated financial statements include the accounts of the
Company and its wholly owned subsidiaries. All significant intercompany accounts
and transactions have been eliminated.

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 the disclosure of
contingent assets and liabilities at the date of the financial statements as
well as the reported amounts of revenues and expenses during the reporting
period. Actual results could differ from those estimates, and such differences
may be material to the financial statements.

INCOME TAXES

The Company accounts for income taxes under Statement of Financial Accounting
Standards No. 109, "Accounting for Income Taxes" (FAS 109). Under FAS 109,
deferred tax assets and liabilities are determined based on the differences
between the financial reporting and tax bases of assets and liabilities and are
measured using the enacted tax rates that will be in effect when the differences
are expected to reverse.

PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment are stated at cost, net of accumulated
depreciation and amortisation. Depreciation and amortisation is provided on a
reducing balance basis at the rate of 25% per year.

INTANGIBLE ASSETS

Intangible assets consist of acquired development and marketing rights to
platform technologies. Acquired development and marketing rights are stated at
their cost less accumulated amortisation. Amortisation is provided on a
straight-line basis over 20 years.

RESEARCH AND DEVELOPMENT

Research and Development costs are charged to expense as incurred.

NET LOSS PER SHARE

Basic net loss per share is computed using the weighted average number of common
shares outstanding during the periods. Diluted net loss per share is computed
using the weighted average number of common shares and potentially dilutive
common shares outstanding during the periods.

Options to purchase 500,000 shares of common stock have not been included in the
calculation of net loss per share as their effect would have been anti-dilutive.

FOREIGN CURRENCY TRANSLATION

The functional currency of the Company is Pounds Sterling. The functional
currency of the Company and its subsidiary, Old Bioenvision, was previously the
US dollar. Following various re-organisations (see Note 2) all historical
amounts have been restated with the adoption of Pounds Sterling as the
functional currency. This did not have a material impact.

2. BUSINESS COMBINATIONS

During the two years ended June 30, 1999 the Company and its subsidiaries
completed a number of mergers and acquisitions. The Company merged with Old
Bioenvision, Inc. (" Old Bioenvision") on January 5, 1999, in exchange for
7,013,897 shares which was accounted for as a reorganisation of companies under
common control. Previously, on September 8, 1998, Bioenvision had merged with
Eurobiotech Group Inc. ("Eurobiotech") in exchange for 2,500,000 shares of its
common stock which was accounted for as a combination of a reorganisation of
companies under common control and the purchase of a minority interest. The
purchase price for the minority interest was (pound)15,541 and has been
allocated as follows:

                                                                  (pound)

      Technology rights                                           682,650
      Less negative goodwill                                     (667,109)
                                                                 --------
      Total consideration                                          15,541

The value of technology is based on an assessment performed by an independent
specialist.

In addition, on July 3, 1998 Old Bioenvision merged with Biotechnology &
Healthcare Ventures Limited ('BHV') in exchange for 4,150,000 shares of common
stock in a transaction accounted for as a reorganisation of companies under
common control.

On May 21, 1998 BHV acquired Biomed UK Limited ("Biomed") in exchange for
300,000 shares of common stock and warrants to purchase up to $900,000 of BHV
common stock. Following the acquisition of BHV by Old Bioenvision, the agreement
was amended which resulted in 300,000 shares of common stock in Old Bioenvision
being issued in lieu of the cancellation of the BHV stock and warrants. Proforma
information for the transaction has not been presented as Biomed had immaterial
operations, assets and liabilities at the date of acquisition. The value of the
shares issued was not material and approximated the value of Biomed's tangible
net assets at the date of acquisition.

Further, on May 20, 1998 BHV acquired Bioheal Limited ("Bioheal") in exchange
for 450,000 shares of common stock and warrants to purchase up to $1,600,000
worth of BHV common stock. Following the acquisition of BHV by Old Bioenvision,
the agreement was amended which resulted in 535,000 shares of common stock in
Old Bioenvision being issued in lieu of the cancellation of the BHV stock and
warrants. Proforma information for the transaction has not been presented as
Bioheal had immaterial operations, assets and liabilities at the date of
acquisition. The value of the shares issued was not material and approximated
the value of Bioheal's tangible net assets at the date of acquisition.

The following table reconciles the operating results for prior periods to the
amounts reflecting restatement of prior periods to include the results of Old
Bioenvision:

Rent expense for 1998 and 1999 was (pound)nil and (pound)9,000 respectively and
(pound)18,000 for the period from August 16, 1996 (inception) through June 30,
1997.

The Company uses office space for its executive offices which it receives from
its financial advisor at no cost.

6. INCOME TAXES

Due to operating losses and the inability to recognise corporation tax benefit
therefrom, there is no provision for income taxes for the years ended June 30,
1998 and 1999 and for the period from August 16, 1996 (inception) through June
30, 1999.

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

                                                        1998         1999
                                                     (pound)      (pound)
      Capitalised start-up costs (US)                141,610       48,604
      Net operating loss carry forwards (US)          94,147       78,967
                                                    --------     --------
      Total deferred tax assets                      235,757      127,571
      Valuation allowance                           (235,757)    (127,571)
                                                    --------     --------
      Net deferred tax asset                              --           --
                                                    ========     ========

As of June 30, 1999 the Company had net operating loss carry forwards of
approximately (pound)151,000 which do not expire under UK law.

7. STOCKHOLDERS' EQUITY

In January 1997, the Board of Directors and stockholders approved a 1 for 1.986
reverse split of the Company's common stock and in January 1999 effected at 1
for 15 reverse stock split. All share and per share amounts in the accompanying

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

8. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

On September 8, 1998 the Company entered to an agreement with Glen Investments,
Limited, a Jersey, Channel Islands corporation wholly owned by Kevin R. Leech,
whereby Glen Investments has agreed to loan funds to the Company on an as-needed
basis based upon previously agreed budgets. Mr Leech is a private investor who
is also the sole owner of Phoenix Ventures Limited, a Guernsey, Channel Islands
corporation and the holder of approximately 19% of the outstanding shares of
Common Stock of the Company. In exchange for its agreement to loan funds to the
Company, the Company issued to Glen Investments options to purchase up to
500,000 shares of Common Stock at an exercise price of $1.00 per share, all of
which options are currently exercisable. As such options were issued at an
exercise price greater than the fair value of common stock, no amount has been
included in the statement of operations to reflect the issuance of the options.
(pound)219,330 was outstanding under this agreement at June 30, 1999.

As of June 30, 1998 and 1999 financial advisors to the Company held 325,036
shares in the Company, which were issued in exchange for financial planning
services rendered. These services are reflected in the statement of operations
as start-up and organisational costs. They are valued at $0.01 per share, which
reflects the most recent transaction for shares.

In May 1998, Bioheal Ltd., a subsidiary of the Company, entered into an
agreement with Christopher B. Wood, the Chairman of the Board and Chief
Executive Officer of the Company, to co-develop a gene marker and
immunomodulator system for use in gene therapy and related technologies. Under
the terms of the agreement, Bioheal was granted the exclusive license to make,
use and sell products derived from technology, and to utilize technical
information related to the technology to obtain patent and other proprietary
rights to products developed by Bioheal and its collaborators from the
technology for a term expiring on the date of expiration of all current and
future patents covered by the agreement, subject to earlier termination under
certain circumstances. In consideration of the licenses granted to Bioheal,
Bioheal agreed to pay to Dr. Wood, among other things, a royalty of 10% of the
gross sales revenues of all products, less and discounts or deductions for
value-added taxes. In addition, Bioheal has agreed to pay, among other things,
certain costs associated with pre-clinical development and clinical trials of
such products. Under the terms of the agreement, the pre-clinical costs are not
to exceed $1,500,000, and the clinical trial costs are not to exceed $4,000,000,
unless agreed by both parties.

9. SUBSEQUENT EVENT

During October 1999 the stockholders approved the offering, through a private
placement, of 1,000,000 shares of Preferred Stock in the Company.

financial  report  or, if  permitted,   a copy from each  sublicensee  and other
commercialization entity(ies).

G.  The  parties  will  promptly  share  all  information  generated  under  the
Co-Development Program pursuant to the confidentiality  provisions of Article 21
and with particular respect to the pre-clinical studies and clinical trials.

9. RECORDS

Bioheal  shall  keep  accurate  records  of all  operations  affecting  payments
hereunder,  and shall permit C B Wood or a duly authorized  agent to inspect all
such records and to make copies of or extracts from such records  during regular
business hours throughout the term of this Agreement and for a reasonable period
of not less than three (3) years thereafter. The fees charged for an audit shall
be  paid  by C B  Wood;  provided,  however,  that  if  an  audit  discloses  an
underpayment  by Bioheal of more than five percent (5%) for such audited period,
Bioheal  shall  pay  the  reasonable  fees  and  expenses  charged  by the  firm
conducting the audit.

10. OWNERSHIP OF THE TECHNOLOGY, TECHNICAL INFORMATION AND IMPROVEMENTS

C B Wood and  Bioheal  shall  each  retain  full  ownership  of  their  existing
intellectual  property rights including rights in the process of being protected
and rights conceived but not yet reduced to practice as of the effective date of
this Agreement.

All  Improvements  developed  under  projects  funded,  in whole or in part,  by
Bioheal shall be owned by C B Wood and shall be included in the licenses granted
in this Agreement.  In the event that a conflicting obligation prevents C B Wood
from including  such an  Improvement,  C B Wood shall use reasonable  efforts to
assist Bioheal to obtain rights from the appropriate third party or parties.

All  Improvements  made during the first three (3) years from the effective date
of the Agreement and not developed under projects  funded,  in whole or in part,
by Bioheal,  shall be owned by C B Wood and if deemed  reasonably  necessary for
Bioheal's  practice  of  the  Technology,  without  which  such  practice  would
constitute an infringement of Bioheal's rights,  shall be included to the extent
necessary,  as  decided  solely by C B Wood,  in the  licenses  granted  in this
Agreement,  unless inclusion is not possible due to C B Wood's  obligations to a
third party. In the event that a conflicting  obligation  prevents C B Wood from
including such an Improvement, he shall use reasonable efforts to assist Bioheal
to obtain rights from the appropriate third party or parties.

Bioheal  shall  have  the  first  right of  negotiation  to a  license  or other
commercial  arrangement to any C B Wood  intellectual  property  developed under
projects funded,  in whole or in part, by Bioheal,  which does not constitute an
Improvement.

suggestions  regarding  prosecution  tactics and strategy.  Notwithstanding  the
foregoing,  Bioheal shall have the right to take such actions as are  reasonably
necessary,  in its good faith judgement, to preserve all rights under the Patent
and Improvement  throughout the Territory.  As soon as practical,  subsequent to
the filing of any  prosecution  document,  Bioheal shall provide C B Wood with a
copy of such  document.  In  addition,  Bioheal  shall  copy C B Wood  with  any
official  office action and responses  and  submissions.  Bioheal shall bear the
expenses of the activities noted in this Article 11.E.

participate  and be represented in any such  prosecutions  by his own counsel at
his own expense.

If C B Wood notifies Bioheal of his desire to institute suit for infringement(s)
and Bioheal  fails to exercise its first right to do so within  ninety (90) days
of such notice,  then C B Wood may, at his own  expense,  bring suit or take any
other appropriate action. At Bioheal's expense, Bioheal will reasonably assist C
B Wood in such  prosecutions if so requested by C B Wood, and will lend its name
to such actions if requested by C B Wood or required by law. Notwithstanding the
foregoing C B Wood shall have the right to participate and be represented in any
such prosecutions by his own counsel at his own expense.

No settlement of any suspected  infringement(s),  whether or not a suit has been
instituted,  may be entered into without the express written consent of C B Wood
and Bioheal.

     Any amounts  recovered  pursuant to an  infringement  suit,  settlement  or
otherwise  shall be retained by and be the  property of the party  bringing  the
action. In the event Bioheal receives any monies or other  consideration  from a
third  party  as a  result  of  Bioheal's  exercise  of its  rights  under  this
Agreement, Bioheal shall first be reimbursed for expenses incurred and paid for,
C B Wood shall then receive a portion of the  remainder in  accordance  with the
applicable  provision(s)  of Article 6 as  applied  to all such  monies or other
considerations  whether  such  monies or other  considerations  are  denoted  as
"royalties," "damages," "releases" from prior acts, or any other designation.

     If  Bioheal  fails  to  exercise  its  first  right to  institute  suit for
infringement(s)  and C B Wood elects not to institute  suit, then C B Wood shall
provide  Bioheal  with at least  sixty  (60)  days  notice of its  intention  to
terminate  Bioheal's  licenses  granted in those  jurisdictions  affected by the
infringement or to take any other action it sees fit in its best judgement.

13. REVOCATION PROCEEDINGS

any proceedings for the revocation of any Patent, patents or Improvements in any
country in the Territory licensed hereunder to Bioheal,  such party shall notify
the other party promptly.  Bioheal shall defend any such  proceedings at its own
expense, in its own name.

B. C B Wood shall have the right to participate in such  revocation  proceedings
at Bioheal's expense, and will lend its name to such proceedings if requested by
C B Wood or required by law.  Sublicensees  of Bioheal shall also have the right
to participate in such revocation proceedings.

by the  provisions  of  this  Agreement,  (ii) a  party  or  its  Affiliates  or
Sub-licensees  may disclose  Confidential  Information to  governmental or other
regulatory  authorities  to  the  extent  that  such  disclosure  is  reasonably

Patent application covering information contained in the proposed publication or
presentation   should  be  filed,   the  party   proposing  the  publication  or
presentation  shall delay such  publication or presentation for up to sixty (60)
days after the  thirty  (30) days  outlined  in clause B (i) above to allow such
filing to be made.

entered  into  the  public  domain  through  no  fault  of  Biomed  or  Biomed's
subsidiaries.  Disclosure of Technical  Information is permitted without a prior
written  consent  of  EuroLife  to the  extent  required  by  statute,  rule  or
regulation  of a governing  body during the course of Biomed's  normal  business
practices,  or in the  application or  prosecution of an application  for patent
rights,  or in  connection  with  securing  financing  for  the  development  or
commercialization  of the Technology or a Product.  Biomed shall inform EuroLife
of any such  disclosure and use its best efforts to protect its  confidentiality
under such  disclosure.  Any combination of Technical  Information  shall not be
considered in the public domain merely because  individual  elements thereof are
in the public  domain.  To the extent  that any such  Technical  Information  is
disclosed to Biomed's  sublicensees  and  purchasers  of Biomed's  Product(s) or
services, the agreements contained in this Section shall be made by Biomed under
a  confidentiality  agreement  to  apply  to and be made  binding  upon all such
parties.

(2) The  fact  that  some or all of the  Technical  Information  becomes  public
knowledge  shall not affect the financial  obligations  for use of the Technical
Information licensed under this Agreement if such Technical Information was used
or usable in the discovery, development,  manufacture, or approval for sale of a
Product within the Field.

4. LICENSE FEE AND RESEARCH AND DEVELOPMENT FUNDING

Biomed shall pay the costs of any further  pre-clinical  development work deemed
necessary  prior to  commencing  clinical  trials,  and this shall  include  the
development  of the  Product  for  other  therapeutic  applications,  the use of
different  formulations and preparations of the Product.  The pre-clinical costs
not to exceed $1.5 million, unless agreed to buy both parties.

B. Biomed shall pay the costs of clinical  trials of the  Product.  The costs of
such development will not exceed $4 million (four million U.S. dollars).

C Biomed shall pay the cost of prosecuting,  filing and maintaining  patents and
defending  revocation  proceedings  on patents and patent  applications,  on the
Product within the Territory.

5. ACQUISITION

     Acquisition  of the  Licensed  Technology  is meant in its  broadest  sense
including assignment,  transfer, sublicense, merger, joint venture and so on and
so forth.

A. If all or part of the rights  granted to Biomed are acquired by a third party
all current or future payments  derived by Biomed from the transfer,  whether in
cash, shares,  property or any other form of payment,  including but not limited
to up-front  payments,  milestone payments and royalties will be divided equally
between


<PAGE>




EuroLife and Biomed, after repayment to Biomed of all development costs incurred
by Biomed.

ROYALTY PAYMENTS

A. Biomed  shall have  exclusive  rights to market the Product in the  Territory
under the following  terms:  For the Patent and Technical  Information  licenses
granted  herein,  Biomed  shall pay to EuroLife a royalty of 10% of the Net Sale
Price of all  Product(s)  sold to an  unaffiliated  third party,  likely to be a
distributor or wholesaler,  but not limited to such, where Biomed is responsible
for the marketing of the Product.

B. If the Product  incorporates  inventions,  patents, or technical  information
that is necessary for the successful  commercialization  of the Product and that
is obtained from sources other than EuroLife,  the Parties agree to negotiate in
good faith a new royalty  rate to reflect the  contribution  of such third party
inventions, patents, or technical information, but in no event shall the royalty
rate be reduced by more than 50%.

C.  If this  Agreement  is for  any  reason  terminated  before  all the  earned
royalties  herein provided for have been paid,  Biomed shall  immediately pay to
EuroLife any remaining  unpaid  balance of earned  royalties even though the due
date provided in Article 8 has not been reached.

If Biomed shall sell the rights to the Technology in combination  with the sale,
acquisition,  merger or  disposition  of Biomed Ltd.,  Biomed,  EuroLife and the
third  party(ies)  shall  negotiate in good faith the specific  details for such
sale  of  rights,  subject  to the  approval  of  EuroLife  which  shall  not be
unreasonably withheld.

7.   SUBLICENSING

A. Biomed shall have the right to sublicense in the Field for the Territory.

B. Biomed will keep EuroLife  routinely  updated on progress of discussions  and
negotiations  with  potential  sub-licensees.  EuroLife  shall have the right to
review the form of sublicenses to be granted hereunder prior to the execution of
the same by Biomed.  Biomed agrees that sublicense  agreements  shall conform in
all material respects to the terms and conditions of this Agreement. If EuroLife
has not objected within thirty (30) days of receiving the form of such agreement
describing  the  material  terms,  Biomed  may  proceed to  negotiate  and grant
sublicenses without further review by EuroLife if the form of the sublicense has
not  materially  changed.  Biomed  shall  provide  EuroLife  with a copy of each
sublicense  within  thirty  (30) days of  execution,  and shall not grant to its
sub-licensees any rights not conveyed by this Agreement.

C. If this Agreement is terminated for any reason,  except breach of contract by
Biomed,  any  sublicense  shall  automatically  transfer  to  EuroLife,   unless
sublicensee is in breach or default of sublicense,  and remain in full force and
effect so long as


<PAGE>


the  sublicensees  performs the obligations of the  sublicense,  and Biomed will
execute such documents as may be requested by EuroLife to attest to the transfer
to EuroLife of all  sublicense  rights,  including  the right to receive  future
payments.

8.   PAYMENTS AND REPORTS

Payments owed to EuroLife shall be payable within thirty (30) days of receipt by
Biomed  except as stated  otherwise  elsewhere in this  Agreement and except for
royalties and  profit-sharing  compensation  as a result of direct  marketing of
Product by Biomed.

B. Royalties and  profit-sharing  compensation owed to EuroLife as a consequence
of direct  marketing of Product by Biomed shall be due for each calendar quarter
beginning  with the first  calendar  quarter in which  sales  occur and shall be
payable to EuroLife  within  forty-five  (45) days following the last day of the
applicable calendar quarter.  All payments from Biomed to EuroLife shall be made
in Pounds  Sterling  (pound) by bank credit  transfer to EuroLife at the address
designated in writing by EuroLife from time-to-time.

C. In the event that  Biomed is  prevented  from  making any payment to EuroLife
under  this  Agreement  by virtue of  restrictions  on  currency  conversion  or
repatriation under the statutes,  laws, codes or governmental regulations of the
country from which the payment is to be made,  then such payments may be paid by
depositing them in the currency in which accrued to EuroLife's account in a bank
acceptable to EuroLife in the country whose  currency is involved.  If the local
currency  cannot be converted or remitted to EuroLife  within twelve (12) months
from the initial  deposit,  Biomed  shall pay EuroLife  the  equivalent  of such
amount  at the  initially  computed  conversion  rate  (including  any  interest
earnings)  in  Pounds  Sterling   (pounds)  and  the  local  currency  shall  be
transferred to an account in a bank acceptable to EuroLife in that country.

D.  Payments to EuroLife  hereunder  shall be deemed paid as of the day on which
they are received at the address designated.  Any part of a payment which is not
paid on or before the date when due shall accrue interest thereon from such date
until the date of its payment in full at two (2) percentage  points over the per
annum  interest  rate  published as the "Prime Rate" in The Wall Street  Journal
(Eastern  Edition),  but in no event  shall such rate  exceed the  maximum  rate
permitted by applicable law.

each calendar  quarter a report,  certified by the chief  financial  officer (or
equivalent)  of Biomed,  setting forth in reasonable  detail the  calculation of
payments made during the quarter and for each calendar quarter,  including gross
sales,  value added  taxes,  number of units sold,  unit price and the like on a
country-by-country  basis by  Biomed,  sublicensees,  joint  ventures  and their
affiliates.

F. The Biomed report to EuroLife  shall be supported by and based upon a similar
financial  report  or, if  permitted,  a copy from  each  sublicensee  and other
commercialization entity(ies).

G.  The  parties  will  promptly  share  all  information  generated  under  the
Co-Development Program pursuant to the confidentiality  provisions of Article 21
and with particular respect to the pre-clinical studies and clinical trials.

9.   RECORDS

Biomed  shall  keep  accurate  records  of  all  operations  affecting  payments
hereunder,  and shall permit EuroLife or a duly authorized  agent to inspect all
such records and to make copies of or extracts from such records  during regular
business hours throughout the term of this Agreement and for a reasonable period
of not less than three (3) years thereafter. The fees charged for an audit shall
be  paid  by  EuroLife;  provided,  however,  that  if  an  audit  discloses  an
underpayment  by Biomed of more than five percent (5%) for such audited  period,
Biomed shall pay the reasonable fees and expenses charged by the firm conducting
the audit.


10. OWNERSHIP OF THE TECHNOLOGY,  TECHNICAL INFORMATION AND IMPROVEMENTS

EuroLife  and  Biomed  shall  each  retain  full  ownership  of  their  existing
intellectual  property rights including rights in the process of being protected
and rights conceived but not yet reduced to practice as of the effective date of
this Agreement.

All Improvements developed under projects funded, in whole or in part, by Biomed
shall be owned by EuroLife and shall be included in the licenses granted in this
Agreement.  In the event that a conflicting  obligation  prevents  EuroLife from
including such an Improvement,  EuroLife shall use reasonable  efforts to assist
Biomed to obtain rights from the appropriate third party or parties.

All  Improvements  made during the first three (3) years from the effective date
of the Agreement and not developed under projects  funded,  in whole or in part,
by Biomed,  shall be owned by EuroLife and if deemed  reasonably  necessary  for
Biomed's  practice  of  the  Technology,   without  which  such  practice  would
constitute an infringement of Biomed's  rights,  shall be included to the extent
necessary,  as  decided  solely by  EuroLife,  in the  licenses  granted in this
Agreement,  unless inclusion is not possible due to EuroLife's  obligations to a
third party. In the event that a conflicting  obligation  prevents EuroLife from
including such an Improvement,  he shall use reasonable efforts to assist Biomed
to obtain rights from the appropriate third party or parties.

Biomed  shall  have  the  first  right  of  negotiation  to a  license  or other
commercial  arrangement to any EuroLife  intellectual  property  developed under
projects  funded,  in whole or in part, by Biomed,  which does not constitute an
Improvement.

hereunder  and Biomed  shall  promptly  provide  comments,  if any, to EuroLife.
EuroLife shall confer with Biomed, and make reasonable efforts to adopt Biomed's
suggestions  regarding  prosecution  tactics and strategy.  Notwithstanding  the
foregoing,  Biomed shall have the right to take such  actions as are  reasonably
necessary,  in its good faith judgement, to preserve all rights under the Patent
and Improvement  throughout the Territory.  As soon as practical,  subsequent to
the filing of any  prosecution  document,  Biomed shall provide  EuroLife with a
copy of such document. In addition, Biomed shall copy EuroLife with any official
office action and responses and  submissions.  Biomed shall bear the expenses of
the activities noted in this Article 11.E.

 .E.  Biomed will inform  EuroLife at least sixty (60) days prior to any decision
having  as  a  result  the  failure  to  file,  or  the  abandonment  of  Patent
applications or failure to maintain a Patent,  Patents and Improvements licensed
hereunder so that Biomed may take over and maintain such Patent and Improvements
in force.

 .F. Provided that Biomed has been informed by Biomed at least sixty (60) days in
advance,  in the event that Biomed decides not to pay patenting  expenses in any
jurisdiction,  EuroLife may elect to maintain  such Patent and  Improvements  in
force and terminate  Biomed's  licenses granted as for the jurisdiction in which
Biomed abandoned or failed to file or maintain such Patent rights.

12.  INFRINGEMENT BY THIRD PARTY

Either party shall  notify the other party of any  suspected  infringement  by a
third party of the Patent in the Field and the  Territory,  and each party shall
inform the other of any evidence of such infringement(s).

Biomed shall have the first right to institute suit for  infringement(s)  in the
Field and Territory so long as this  Agreement  remains  exclusive.  At Biomed's

Biomed or required


<PAGE>


by  law.  Notwithstanding  the  foregoing  EuroLife  shall  have  the  right  to
participate  and be represented in any such  prosecutions  by his own counsel at
his own expense.

If EuroLife notifies Biomed of his desire to institute suit for  infringement(s)
and Biomed fails to exercise its first right to do so within ninety (90) days of
such notice, then EuroLife may, at his own expense, bring suit or take any other
appropriate action. At Biomed's expense,  Biomed will reasonably assist EuroLife
in such prosecutions if so requested by EuroLife, and will lend its name to such
actions if  requested  by  EuroLife  or  required  by law.  Notwithstanding  the
foregoing EuroLife shall have the right to participate and be represented in any
such prosecutions by his own counsel at his own expense.

No settlement of any suspected  infringement(s),  whether or not a suit has been
instituted,  may be entered into without the express written consent of EuroLife
and Biomed.

Any amounts recovered pursuant to an infringement suit,  settlement or otherwise
shall be retained by and be the property of the party  bringing  the action.  In
the event Biomed receives any monies or other  consideration  from a third party
as a result of Biomed's  exercise  of its rights  under this  Agreement,  Biomed
shall first be reimbursed  for expenses  incurred and paid for,  EuroLife  shall
then  receive a portion  of the  remainder  in  accordance  with the  applicable
provision(s) of Article 6 as applied to all such monies or other  considerations
whether  such  monies  or  other  considerations  are  denoted  as  "royalties,"
"damages," "releases" from prior acts, or any other designation.

If  Biomed   fails  to  exercise   its  first  right  to   institute   suit  for
infringement(s)  and EuroLife  elects not to institute suit, then EuroLife shall
provide  Biomed  with at least  sixty  (60)  days  notice  of its  intention  to
terminate  Biomed's  licenses  granted in those  jurisdictions  affected  by the
infringement or to take any other action it sees fit in its best judgement.

13. REVOCATION PROCEEDINGS

In the event either party becomes aware of the  institution  by a third party of
any proceedings for the revocation of any Patent, patents or Improvements in any
country in the Territory licensed  hereunder to Biomed,  such party shall notify
the other party  promptly.  Biomed shall defend any such  proceedings at its own
expense, in its own name.

B. EuroLife shall have the right to participate in such  revocation  proceedings
at Biomed's expense,  and will lend its name to such proceedings if requested by
EuroLife or required by law. Sublicensees of Biomed shall also have the right to
participate in such revocation proceedings.

C. Settlement of any revocation  proceedings shall be subject to the approval of
EuroLife; such approval shall not be unreasonably withheld.

involving a claim by a third party,  or in  settlement  thereof,  such  recovery
shall be applied and shared as mutually agreed.

15.  REPRESENTATIONS

A. EuroLife represents that it has the right to grant all of the rights herein.

any product,  process,  or service,  relating to, or developed pursuant to, this
Agreement  is  being  commercially  distributed  or  sold  by  Biomed  or  by  a
sublicensee,  affiliate or agent of Biomed.  Biomed shall  furnish to EuroLife a
certificate  of  insurance  evidencing  such  coverage  and  periodically,  upon
request, provide evidence that the coverage is still in effect.

18. TERM AND TERMINATION

A. This  Agreement  shall  commence on the  Effective  Date and,  unless  sooner
terminated under this Article 18, shall expire upon the later of: (i) expiration

cease to carry out its business as related to the Product(s), become bankrupt or
insolvent,  apply for or consent to the  appointment  of a trustee,  receiver or
liquidator of its assets or seek relief under any law for the aid of debtors.

      Biomed shall inform EuroLife of its intention to file a voluntary petition
in  bankruptcy  or of  another's  intention to file an  involuntary  petition in
bankruptcy  to be  received  at least  thirty  (30) days prior to filing  such a

by the  provisions  of  this  Agreement,  (ii) a  party  or  its  Affiliates  or
Sub-licensees  may disclose  Confidential  Information to  governmental or other
regulatory  authorities  to  the  extent  that  such  disclosure  is  reasonably
necessary  to  obtain  patents  or  regulatory   authorizations,   provided  the
disclosing party shall request confidential treatment thereof, and (iii) a party
may disclose Confidential  Information as required by applicable law, regulation
or  judicial  process,  provided  that such party shall give the other party (x)

publication or presentation. The non-publishing/non-presenting  party shall then
have thirty (30) days to review and comment on the  manuscript or  presentation,
and the publishing/presenting  party agrees to delete any information identified
by the non-publishing/non-presenting  party as its Trade Secrets or Confidential
Information.

     (ii) In the event the non-publishing/non-presenting party determines that a
Patent application covering information contained in the proposed publication or
presentation   should  be  filed,   the  party   proposing  the  publication  or
presentation  shall delay such  publication or presentation for up to sixty (60)
days  after the thirty  (30) days  outlined  in clause  B(i) above to allow such
filing to be made.

     Each party  shall  provide the other  party with the prior  opportunity  to
review and approve any press releases or similar public announcements concerning
this Agreement or clinical,  regulatory and commercial  developments  related to
Products as soon as  practicable,  but in no event later than 24 hours before an
announcement  is made.  Biomed  shall not use the name of EuroLife or  otherwise
refer to any organization related to EuroLife,  except with the written approval
of EuroLife, such approval not to be unreasonably withheld.

WHEREAS,  Bioenvision  recognizes  that its anticipated  business  activity will
encompass the practice of technology that requires a license under patents owned
by Stegram; and

WHEREAS, Bioenvision wishes to acquire certain rights to practice the inventions
of such patents and technical information; and

WHEREAS the parties have signed a "Terms for Co-Development Agreement" set forth
in Appendix I, to enter into this Agreement, and

NOW THEREFORE,  in  consideration  of the mutual  covenants herein contained and
intending to be legally bound thereby, the parties agree as follows:

claimed in the Patent(s).

E. Improvement means those  unencumbered  technology  advances in the Technology
made by or on behalf  of  Stegram  during  the term of this  Agreement  that are
either within the scope of and would  constitute an  infringement  of the Patent
claims or use Technical  Information and are within the Field.  Stegram shall be
obligated to include within the licenses granted only those Stegram improvements
developed  during  the  first  three (3) years  from the  effective  date of the
Agreement which would be reasonably deemed necessary for Bioenvision's  practice
of  the  Technology,  and  without  which  such  practice  would  constitute  an
infringement  of  Stegram's  rights,  unless such grant is not  possible  due to
Stegram's  obligations  to a third  party.  Notwithstanding  the  limitation  of
Stegram's  obligation  set  forth in the  previous  sentence,  all  Improvements
developed  under projects  funded,  in whole or in part, by Bioenvision  will be
included  in the  licenses  granted  in  this  Agreement.  In the  event  that a

Agreement shall apply.

                      2. LICENSE AND CO-DEVELOPMENT PROGRAM

A. The  parties  to this  Agreement  hereby  agree  to  jointly  co-develop  the
Technology  according to the terms of this Agreement which supersedes the "Heads
of Terms for a  Co-Development  Agreement" set forth in Appendix I and all other
written  or  verbal  agreements,   express  or  implied,   between  Stegram  and
Bioenvision relating to co-development of the Technology.

B.  Stegram  hereby  grants to  Bioenvision,  to the extent of the Field for the
Territory,  an exclusive  license to make,  have made, use and sell  Product(s),
provided  Bioenvision  sells Product(s)  under existing  Stegram  trade-marks or
under new  trade-mark(s) to be agreed by both parties and the terms of clause 6H
shall apply to such new trade-mark(s).

C. The exclusive  license set forth herein shall remain exclusive for so long as

<PAGE>


any such Technical  Information at any time: (i) with the prior written  consent
of Stegram, or (ii) to the extent necessary,  to Bioenvision's  sublicensees and
purchasers  of  Bioenvision's  Product(s)  or services,  or (iii) after the same

business  practices,  or in the application or prosecution of an application for
patent rights,  or in connection with securing  financing for the development or
commercialization  of the  Technology  or a Product.  Bioenvision  shall  inform
Stegram  of any  such  disclosure  and use  its  best  efforts  to  protect  its
confidentiality under such disclosure.  Any combination of Technical Information
shall not be considered in the public domain merely because individual  elements
thereof  are in the  public  domain.  To the  extent  that  any  such  Technical
Information  is  disclosed  to  Bioenvision's  sublicensees  and  purchasers  of
Bioenvision's  Product(s) or services,  the agreements contained in this Section
shall be made by Bioenvision under a  confidentiality  agreement to apply to and
be made binding upon all such parties.

(2) The  fact  that  some or all of the  Technical  Information  becomes  public
knowledge  shall not affect the financial  obligations  for use of the Technical
Information licensed under this Agreement if such Technical Information was used
or usable in the discovery, development,  manufacture, or approval for sale of a
Product within the Field.

               4. LICENSE FEE AND RESEARCH AND DEVELOPMENT FUNDING

A. Bioenvision shall pay the costs of any further pre-clinical  development work
deemed necessary prior to commencing clinical trials, and this shall include the
development  of the  Product  for  other  therapeutic  applications,  the use of

     Acquisition  of the  Licensed  Technology  is meant in its  broadest  sense
including assignment,  transfer, sublicense, merger, joint venture and so on and
so forth.

A. If all or part of the rights granted to  Bioenvision  are acquired by a third
party all current or future payments  derived by Bioenvision  from the transfer,
whether in cash,  shares,  property or any other form of payment,  including but
not limited to up-front  payments,  milestone  payments  and  royalties  will be
divided equally between Stegram and Bioenvision,  after repayment to Bioenvision
of all development costs incurred by Bioenvision.

                               6. ROYALTY PAYMENTS

A.  Bioenvision  shall  have  exclusive  rights to  market  the  Product  in the
Territory under the following  terms:  For the Patent and Technical  Information
licenses  granted herein,  Bioenvision  shall pay to Stegram a royalty of 10% of
the Net Sale Price of all Product(s) sold to an unaffiliated third party, likely
to be a distributor or wholesaler, but not limited to such, where Bioenvision is
responsible for the marketing of the Product.

B. If the Product  incorporates  inventions,  patents, or technical  information
that is necessary for the successful  commercialization  of the Product and that
is obtained from sources  other than Stegram,  the Parties agree to negotiate in
good faith a new royalty  rate to reflect the  contribution  of such third party
inventions, patents, or technical information, but in no event shall the royalty
rate be reduced by more than 50%.

C.  If this  Agreement  is for  any  reason  terminated  before  all the  earned
royalties herein provided for have been paid,  Bioenvision shall immediately pay
to Stegram any remaining  unpaid balance of earned royalties even though the due
date provided in Article 8 has not been reached.

D. If Bioenvision  shall sell the rights to the  Technology in combination  with
the sale, acquisition,  merger or disposition of Bioenvision, Inc., Bioenvision,
Stegram and the third  party(ies)  shall  negotiate  in good faith the  specific
details for such sale of rights,  subject to the approval of Stegram which shall
not be unreasonably withheld.

E. After three (3) years from the signing of this  Agreement  Bioenvision  shall
pay a minimum annual  royalty of $50,000 to Stegram.  If sales of Product(s) are
not of sufficient to meet the minimum royalty  Bioenvision  shall have the right
to offset any excess payment  against  future  royalties for up to two (2) years
after the minimum royalty becomes payable.

F.  After  expiry  of the last  patent a  royalty  of 5% of net sale  price  for
products sold directly by Bioenvision shall be payable if Bioenvision  continues
to use any or all trade-marks currently owned by Stegram, or other trade-mark(s)
used by Bioenvision as defined in clause 2B.

                                 7. SUBLICENSING

A.  Bioenvision  shall  have  the  right  to  sublicense  in the  Field  for the
Territory.

B.  Bioenvision will keep Stegram  routinely  updated on progress of discussions
and negotiations with potential  sub-licensees.  Stegram shall have the right to
review the form of sublicenses to be granted hereunder prior to the execution of
the same by Bioenvision.  Bioenvision  agrees that sublicense  agreements  shall
conform in all material  respects to the terms and conditions of this Agreement.
If Stegram has not objected  within  thirty (30) days of  receiving  the form of
such  agreement  describing  the  material  terms,  Bioenvision  may  proceed to
negotiate and grant sublicenses without further review by Stegram if the form of
the sublicense has not materially  changed.  Bioenvision  shall provide  Stegram
with a copy of each sublicense  within thirty (30) days of execution,  and shall
not  grant  to its  sub-licensees  any  Stegram  rights  not  conveyed  by  this
Agreement.

C. If this Agreement is terminated for any reason,  except breach of contract by
Stegram,  any  sublicense  shall  automatically  transfer  to  Stegram,   unless
sublicensee is in breach or default of sublicense,  and remain in full force and
effect so long as the  sublicensees  performs the obligations of the sublicense,
and  Bioenvision  will execute such  documents as may be requested by Stegram to
attest to the transfer to Stegram of all sublicense rights,  including the right
to receive future payments.

                             8. PAYMENTS AND REPORTS

applicable  calendar quarter.  All payments from Bioenvision to Stegram shall be
made in Pounds  Sterling  (pound)  by bank  credit  transfer  to  Stegram at the
address designated in writing by Stegram from time-to-time.

C. In the event that Bioenvision is prevented from making any payment to Stegram
under  this  Agreement  by virtue of  restrictions  on  currency  conversion  or
repatriation under the statutes,  laws, codes or governmental regulations of the
country from which the payment is to be made,  then such payments may be paid by
depositing them in the currency in which accrued to Stegram's  account in a bank
acceptable  to Stegram in the country whose  currency is involved.  If the local
currency  cannot be converted or remitted to Stegram  within  twelve (12) months
from the initial deposit,  Bioenvision  shall pay Stegram the equivalent of such
amount  at the  initially  computed  conversion  rate  (including  any  interest
earnings) in Pounds Sterling (pound), and the local

CONFIDENTIAL                           6

<PAGE>


currency shall be transferred to an account in a bank  acceptable to Bioenvision
in that country.

D.  Payments  to Stegram  hereunder  shall be deemed paid as of the day on which
they are received at the address designated.  Any part of a payment which is not
paid on or before the date when due shall accrue interest thereon from such date
until the date of its payment in full at two (2) percentage  points over the per

quarter,  including gross sales,  value added taxes,  number of units sold, unit
price and the like on a country-by-country  basis by Bioenvision,  sublicensees,
joint ventures and their affiliates.

F. The  Bioenvision  report to Stegram  shall be  supported  by and based upon a
similar  financial  report or, if permitted,  a copy from each  sublicensee  and
other commercialization entity(ies).

G.  The  parties  will  promptly  share  all  information  generated  under  the
Co-Development Program pursuant to the confidentiality  provisions of Article 21
and with particular respect to the pre- clinical studies and clinical trials.

                                   9. RECORDS

Bioenvision  shall keep accurate  records of all operations  affecting  payments
hereunder,  and shall permit Stegram or its duly authorized agent to inspect all
such records and to make copies of or extracts from such records  during regular
business hours throughout the term of this Agreement and for a reasonable period

effective  date of the Agreement and not developed  under  projects  funded,  in
whole or in part,  by  Bioenvision,  shall be  owned by  Stegram  and if  deemed
reasonably necessary for Bioenvision  practice of the Technology,  without which
such practice would  constitute an  infringement of Stegram's  rights,  shall be
included to the extent necessary,  as decided solely by Stegram, in the licenses
granted in this  Agreement,  unless  inclusion  is not possible due to Stegram's
obligations  to a  third  party.  In the  event  that a  conflicting  obligation
prevents  Stegram  from  including  such  an  Improvement,   Stegram  shall  use
reasonable  efforts to assist  Bioenvision to obtain rights from the appropriate
third party or parties.

D.  Bioenvision  shall have the first right of negotiation to a license or other

Stegram.  Stegram shall confer with Bioenvision,  and make reasonable efforts to
adopt  Bioenvision's  suggestions  regarding  prosecution  tactics and strategy.
Notwithstanding the foregoing, Stegram shall have the right to take such actions
as are reasonably necessary, in its good faith judgement, to preserve all rights
under the Patent and Improvement throughout the Territory. As soon as practical,
subsequent  to the filing of any  prosecution  document,  Stegram  shall provide
Bioenvision  with a copy of such  document.  In  addition,  Stegram  shall  copy
Bioenvision   with  any  official  office  action  and  Stegram   responses  and
submissions. Bioenvision shall bear the expenses of the activities noted in this
Article 11.E.

<PAGE>


force and terminate  Bioenvision's  licenses  granted as for the jurisdiction in
which Bioenvision abandoned or failed to file or maintain such Patent rights.

                         12. INFRINGEMENT BY THIRD PARTY

A. Either party shall notify the other party of any suspected  infringement by a
third party of the Patent in the Field and the  Territory,  and each party shall
inform the other of any evidence of such infringement(s).

B. Bioenvision shall have the first right to institute suit for  infringement(s)
in the Field and  Territory  so long as this  Agreement  remains  exclusive.  At
Bioenvision's  expense,  Stegram  will  reasonably  assist  Bioenvision  in such
prosecutions  if so  requested  by  Bioenvision,  and will lend its name to such
actions if  requested by  Bioenvision  or required by law.  Notwithstanding  the
foregoing  Stegram shall have the right to participate and be represented in any
such prosecutions by its own counsel at its own expense.

C.  If  Stegram  notifies  Bioenvision  of its  desire  to  institute  suit  for
infringement(s)  and  Bioenvision  fails to  exercise  its first  right to do so
within  ninety (90) days of such  notice,  then Stegram may, at its own expense,
bring  suit  or  take  any  other  appropriate  action.  At  Stegram's  expense,
Bioenvision will reasonably  assist Stegram in such prosecutions if so requested

required by law.  Notwithstanding the foregoing Bioenvision shall have the right
to participate and be represented in any such prosecutions by its own counsel at
its own expense.

been  instituted,  may be entered  into without the express  written  consent of
Bioenvision and Stegram.

otherwise  shall be retained by and be the  property of the party  bringing  the
action. In the event Bioenvision receives any monies or other consideration from
a third party as a result of  Bioenvision's  exercise  of its rights  under this
Agreement,  Bioenvision shall first be reimbursed for expenses incurred and paid
for,  Stegram shall then receive a portion of the  remainder in accordance  with
the applicable  provision(s) of Article 6 as applied to all such monies or other
considerations  whether  such  monies or other  considerations  are  denoted  as
"royalties," "damages," "releases" from prior acts, or any other designation.

F. If  Bioenvision  fails to  exercise  its first  right to  institute  suit for
infringement(s)  and Stegram  elects not to institute  suit,  then Stegram shall
provide  Bioenvision  with at least sixty (60) days notice of its  intention  to
terminate  Bioenvision's licenses granted in those jurisdictions affected by the
infringement or to take any other action it sees fit in its best judgement.

                           13. REVOCATION PROCEEDINGS

A. In the event either party becomes aware of the  institution  by a third party
of any proceedings for the revocation of any Patent,  patents or Improvements in
any country

other party promptly.  Bioenvision  shall defend any such proceedings at its own
expense, in its own name.

B. Stegram shall have the right to participate in such revocation proceedings at
Bioenvision's  expense,  and will lend its name to such proceedings if requested
by Bioenvision or required by law.  Sublicensees of Bioenvision  shall also have
the right to participate in such revocation proceedings.

Stegram; such approval shall not be unreasonably withheld.

                     14. INFRINGEMENT OF THIRD PARTY RIGHTS

party claim if so requested and at the expense of Bioenvision.

B Stegram shall have the right to  participate  and be  represented  in any such
claim by a third party by its own counsel.

C. No  settlement  of any third  party  claim may be entered  into  without  the
express written consent of Stegram.

parties  recover any damages or other sums in any action,  suit,  or  proceeding
involving a claim by a third party,  or in  settlement  thereof,  such  recovery
shall be applied and shared as mutually agreed.

<PAGE>


shall take into  account on a  country-by-country  or regional  basis but not be
limited to: (i) Product competition;  (ii) utilization,  incorporation and value

contract or patent law or (v) prior payment commitments.

A. In fulfilling their obligations under this Agreement,  it may be desirable or
necessary  for  the  parties  to  disclose  to  one  another  certain  of  their

Information,  the  receiving  party  agrees  to  preserve  such  information  as

     be demonstrated by documentary evidence;

     3. is disclosed to the  receiving  party on a  non-confidential  basis by a
     third party having the right to make such disclosure; or

     4. is independently developed by the receiving party as can be demonstrated
     by documentary evidence.

     In addition,  to the extent reasonably  necessary to fulfil its obligations
or  exercise  its  rights  under  this   Agreement  (i)  a  party  may  disclose
Confidential Information to its Affiliates, Sub-licensees,  consultants, outside
contractors,   research   investigators   and  clinical   investigators,   on  a
need-to-know  basis on condition that such persons or entities agree to be bound
by the  provisions  of  this  Agreement,  (ii) a  party  or  its  Affiliates  or
Sub-licensees  may disclose  Confidential  Information to  governmental or other
regulatory  authorities  to  the  extent  that  such  disclosure  is  reasonably
necessary  to  obtain  patents  or  regulatory   authorizations,   provided  the
disclosing party shall request confidential treatment thereof, and (iii) a party
may disclose Confidential  Information as required by applicable law, regulation
or  judicial  process,  provided  that such party shall give the other party (x)
prior written  notice  thereof,  (y) adequate  opportunity to object to any such
disclosure or to request confidential  treatment thereof, and (z) shall take all
steps  reasonably  possible to minimize the disclosure to that level mandated by
law.

B.  (i) If either  party desires  to  publish  or  present  the  results  of the
Co-Development  Program,  the  publishing/presenting  party  shall  provide  the
non-publishing/non-presenting  party a copy of the  manuscript  of any  proposed
publication or presentation. The non-publishing/non-presenting  party shall then
have thirty (30) days to review and comment on the  manuscript or  presentation,
and the publishing/presenting  party agrees to delete any information identified
by the non-publishing/non-presenting  party as its Trade Secrets or Confidential
Information.

     (ii) In the event the non-publishing/non-presenting party determines that a
Patent application covering information contained in the proposed publication or
presentation   should  be  filed,   the  party   proposing  the  publication  or
presentation  shall delay such  publication or presentation for up to sixty (60)
days  after the thirty  (30) days  outlined  in clause  B(i) above to allow such
filing to be made.

C. Each party shall provide the other party with the prior opportunity to review
and approve any press releases or similar public  announcements  concerning this
Agreement  or  clinical,  regulatory  and  commercial  developments  related  to
Products as soon as  practicable,  but in no event later than 24 hours before an
announcement is made. Bioenvision shall not use the name of Stegram or otherwise
refer to any organization  related to Stegram,  except with the written approval
of Stegram, such approval not to be unreasonably withheld.

shall be found  illegal  or in  conflict  with any valid  controlling  law,  the

question  because  of a decision  by a court of  competent  jurisdiction  of any
country  in  which  this  Agreement  applies,  Stegram,  by  written  notice  to
Bioenvision,  may revise the  provision in question or may delete it entirely so
as to comply with the decision of the said court.

                            23. WAIVER AND ALTERATION

A. The failure of either party to insist, in any one or more instances, upon the
performance  of any of the terms,  covenants or conditions of this Agreement and
to  exercise  any  right  hereunder,  shall  not be  construed  as a  waiver  or
relinquishment of the future performance of any such term, covenant or condition
or the future  exercise of such right,  but the  obligations  of the other party
with respect to such future performance shall continue in full force and effect.

B. A provision of this Agreement may be altered only by a writing signed by both
parties.

     or approval for sale of a Product within the Field.

               4. LICENSE FEE AND RESEARCH AND DEVELOPMENT FUNDING

A.   Eurobiotech shall pay the costs of any further pre-cliical development work
     deemed  necessary  prior to  commencing  clinical  trials,  and this  shall
     include the development of the Product for other therapeutic  applications,
     the use of different  formulations and preparations of the Product and oral
     and  parenteral   preclinical   toxicology.   The  costs  of   pre-clinical
     development  is  anticipated  not to exceed $1 million  (one  million  U.S.
     dollars).  Subject  to  funding  by  Eurobiotech,  SRI  shall  perform  the
     necessary pre-clinical studies whenever appropriate,  unless agreed by both
     parties  that the work would be more  advantageously  performed  by a third
     party.  Eurobiotech's  retention of rights to therapeutic  areas outside of
     cancer  is  contingent  upon  Eurobiotech  providing  funding  support  for
     development  of such  areas  in  accordance  with  the  commitments  of the
     business  development plan, as indicated in Article 10, and as periodically
     reviewed and updated as agreed to by the parties.

B.   Eurobiotech  shall pay the costs of a Phase I clinical trial of the Product
     for hematologic malignancies, to be performed at the Leukemia Unit at the M
     D Anderson Cancer Center in Houston,  Texas.  The costs of such development
     will not exceed $1.25 million (one million,  two hundred and fifty thousand
     U.S.  dollars).  Both parenteral and oral modes of  administration  will be
     studied if  warranted  by  commercial  considerations  and the  preclinical
     toxicology work.

C.   Upon successful completion of Phase I clinical trials Eurobiotech shall pay
     the costs of a  multi-center  Phase II  clinical  trial of the  Product  in
     hematologic malignancies.

D.   Upon successful  completion of Phase II clinical trials SRI and Eurobiotech
     may jointly pay the costs of Phase III clinical  trials and further Product
     development.  If SRI  shall  not  jointly  fund  the  cost of  such  trials
     Eurobiotech may pay the costs in full after paying a non-refundable  option
     fee of $750,000  within 60 days of  completion  and  evaluation of Phase II
     trials or 60 days from the  commencement of Phase III trials,  whichever is
     the earlier. If the parties jointly develop the Product in Phase III trials
     no option fee shall be payable by Eurobiotech.

E.   Eurobiotech   shall  issue  to  SRI  100,000  shares  of  common  stock  of
     Eurobiotech  Group,  Inc.  within  30  days of the  Effective  Date of this
     Agreement.


                                        5

<PAGE>


F.   Eurobiotech  shall pay to SRI the sum of  $750,000  upon the earlier of the
     completion of Phase III trials in Europe or the  initiation of sales of the
     Product in the USA.

G.   Eurobiotech  shall  pay the cost of  prosecuting,  filing  and  maintaining
     patents  and  defending  revocation   proceedings  on  patents  and  patent
     applications, on the Product within the Territory.

H.   Eurobiotech  shall  also  pay  the  costs  as in  4G,  if  any,  for  those
     Sloan-Kettering  Institute for Cancer  Research  ("SKI")  patents which the
     Product might infringe but for the separate  Agreement  between SKI and SRI
     (Appendix  V)  which  provides  SRI  and  Eurobiotech  the  rights  to such
     Sloan-Kettering  Institute for Cancer Research patents in the Field for the
     Territory for the Product.

                                 5. ACQUISITION

     Acquisition  of the  Licensed  Technology  is meant in its  broadest  sense
     including assignment, transfer, sublicense, merger, joint venture and so on
     and so forth.

A.   Prior to Phase III Clinical Trials

     If all or part of the rights granted to Eurobiotech are acquired by a third
     party at,  or before  completion  of Phase II  clinical  trials or prior to
     Phase III  clinical  trials,  all  current  or future  payments  derived by
     Eurobiotech  from the transfer,  whether in cash,  shares,  property or any
     other form of payment,  including  but not  limited to  up-front  payments,
     milestone  payments and royalties will be divided  equally  between SRI and
     Eurobiotech.

B.   During or After Phase III Clinical Trials

     If Eurobiotech  alone funds Phase III clinical trials,  then if all or part
     of the rights are acquired by a third party during or after  completion  of
     Phase III trials,  all current or future  payments  derived by  Eurobiotech
     from the transfer,  whether in cash, shares,  property or any other form of
     payment,  including  but not limited to  up-front  payments  and  milestone
     payments  but  excluding  royalties  will be  shared on the basis of 65% to
     Eurobiotech  and 35% to SRI until 50% of the monies expended by Eurobiotech
     in conducting the Phase III trials are reimbursed. Thereafter, both parties
     shall  receive  50% each of all  payments  derived  form  the  acquisition,
     exclusive of royalty payments.  Royalty payments related to the acquisition
     of  rights  by a third  party in  order to  market  or  further  sublicense
     Product(s) shall be divided in the ratio Eurobiotech 65; SRI 35.

     If a third party  funds the Phase III trials  either in whole or in part in
     return for rights,  the parties to this Agreement shall divide all payments
     including  up-front  payments,  milestone  payments and royalties from that
     third party in equal amounts.


                                        6

<PAGE>


     If the parties to this Agreement share Phase III trial costs equally,  then
     if all or part of the rights are  acquired by a third party during or after
     completion of Phase III trials, all current or future payments derived from
     the acquisition will be divided equally between SRI and Eurobiotech.

C.   Manufacturing

     Should Eurobiotech  manufacture or have Product(s) manufactured for sale to
     any  unaffiliated  third  party  acquirer  such as a  sublicensee  or joint
     venture  prior to,  during or after Phase III  clinical  trials,  SRI shall
     receive 35% of Net Income from such sale(s).

D.   Approval

     The foregoing scenarios (articles 5A and 5B) are subject to the approval of
     SRI which shall not be unreasonably withheld.

                           6. COMMERCIALIZATION STAGE

A.   Eurobiotech  shall  have  exclusive  rights to market  the  Product  in the
     Territory  under  the  following   terms:  For  the  Patent  and  Technical
     Information licenses granted herein, Eurobiotech shall pay to SRI a royalty
     of 7% of the Gross Sales Revenue of all Product(s)  sold to an unaffiliated
     third party,  likely to be a distributor or wholesaler,  but not limited to
     such, where Eurobiotech is responsible for the marketing of the Product. In
     addition to the seven percent of Gross Sales  Revenue,  if the Gross Profit
     Margin from  operations  in any  geographical  area equals or exceeds 31% a
     further  profit-sharing  agreement  will apply,  according to the following
     formula and further exemplified in Appendix IV:

          Gross Profit Margin           Payment as % of Net Income
          -------------------           --------------------------
                 >70%                             20%
               50-70%                             10%
               31-49%                              5%

B.   If the Product incorporates  inventions,  patents, or technical information
     that is necessary for the successful  commercialization  of the Product and
     that is  obtained  from  sources  other  than  SRI,  the  Parties  agree to
     negotiate in good faith a new royalty rate to reflect the  contribution  of
     such third party inventions,  patents, or technical information,  but in no
     event shall the royalty rate be reduced by more than 50%.

C.   If this  Agreement  is for any  reason  terminated  before  all the  earned
     royalties herein provided for have been paid, Eurobiotech shall immediately
     pay to SRI any remaining unpaid balance of earned royalties even though the
     due date provided in Article 8 has not been reached.


                                        7

<PAGE>


D.   If  Eurobiotech  shall  sell  the  rights  to  the  Technology  during  the
     Commercialization Stage, in combination with the sale, acquisition,  merger
     or disposition of Eurobiotech Group, Inc.,  Eurobiotech,  SRI and the third
     party(ies) shall negotiate in good faith the specific details for such sale
     of rights,  subject to the approval of SRI which shall not be  unreasonably
     withheld.

                                 7. SUBLICENSING

A.   Eurobiotech  shall  have  the  right to  sublicense  in the  Field  for the
     Territory.

B.   Eurobiotech will keep SRI routinely  updated on progress of discussions and
     negotiations  with  potential  sublicensees.  SRI  shall  have the right to
     review  the  form of  sublicenses  to be  granted  hereunder  prior  to the
     execution of the same by  Eurobiotech.  Eurobiotech  agrees that sublicense
     agreements  shall  conform  in  all  material  respects  to the  terms  and
     conditions of this  Agreement.  If SRI has not objected  within thirty (30)
     days of receiving the form of such agreement describing the material terms,
     Eurobiotech may proceed to negotiate and grant sublicenses  without further
     review by SRI if the form of the  sublicense  has not  materially  changed.
     Eurobiotech  shall provide SRI with a copy of each sublicense within thirty
     (30) days of  execution,  and shall not grant to its  sublicensees  any SRI
     rights not conveyed by this Agreement.

C.   If this Agreement is terminated  for any reason,  except breach of contract
     by  SRI,  any  sublicense  shall  automatically  transfer  to  SRI,  unless
     sublicensee is in breach or default of sublicense, and remain in full force
     and effect so long as the  sublicensees  performs  the  obligations  of the
     sublicense, and Eurobiotech will execute such documents as may be requested
     by SRI to attest to the transfer to SRI of all sublicense rights, including
     the right to receive future payments.

                             8. PAYMENTS AND REPORTS

A.   Payments  owed to SRI shall be  payable  within ten (10) days of receipt by
     Eurobiotech  except as stated  otherwise  elsewhere in this  Agreement  and
     except for royalties and profit-sharing  compensation as a result of direct
     marketing of Product by Eurobiotech.

B.   Royalties and  profit-sharing  compensation owed to SRI as a consequence of
     direct  marketing of Product by Eurobiotech  shall be due for each calendar
     quarter  beginning with the first calendar quarter in which sales occur and
     shall be payable to SRI within  forty-five (45) days following the last day
     of the applicable calendar quarter.

C.   All  payments  from  Eurobiotech  to SRI shall be made in U.S.  dollars  by
     corporate  check SRI at the address  specified  in Article 34 or an address
     designated in writing by SRI from time-to-time.


                                        8

<PAGE>


D.   With respect to non-dollar denominated payments owed by Eurobiotech to SRI,
     such  payments  shall be  converted  into U.S.  Dollars  at the  conversion
     rate(s)  published in The Wall Street Journal  (Eastern  Edition) as of the
     last business day of the calendar quarter included in the report.

E.   In the event that  Eurobiotech  is prevented from making any payment to SRI
     under this Agreement by virtue of  restrictions  on currency  conversion or
     repatriation under the statutes, laws, codes or governmental regulations of
     the country from which the payment is to be made, then such payments may be
     paid by  depositing  them in the currency in which accrued to SRI's account
     in a bank  acceptable to SRI in the country whose currency is involved.  If
     the local  currency  cannot be converted  or remitted to SRI within  twelve
     (12)  months  from  the  initial  deposit,  Eurobiotech  shall  pay SRI the
     equivalent  of  such  amount  at the  initially  computed  conversion  rate
     (including any interest  earnings) in United States dollars,  and the local
     currency  shall  be  transferred  to an  account  in a bank  acceptable  to
     Eurobiotech in that country.

F.   Payments to SRI hereunder  shall be deemed paid as of the day on which they
     are received at the address designated  pursuant to Article 34. Any part of
     a  payment  which is not paid on or before  the date when due shall  accrue
     interest  thereon  from such date until the date of its  payment in full at
     two (2) percentage points over the per annum interest rate published as the
     "Prime Rate" in The Wall Street Journal (Eastern Edition),  but in no event
     shall such rate exceed the maximum rate permitted by applicable law.

G.   All foreign taxes, assessments and fees of any nature levied or incurred on
     account of any payments  accruing  under this Agreement will be assumed and
     paid by Eurobiotech and not deducted from payments owed to SRI.

H.   Eurobiotech  shall deliver to SRI within forty-five (45) days after the end
     of each calendar quarter a report, certified by the chief financial officer
     (or  equivalent)  of  Eurobiotech,  setting forth in reasonable  detail the
     calculation  of SRI payments  made during the quarter and for each calendar
     quarter,  including gross sales,  value added taxes,  number of units sold,
     unit  price  and the like on a  country-by-country  basis  by  Eurobiotech,
     sublicensees, joint ventures and their affiliates.

I.   The  Eurobiotech  report to SRI  shall be  supported  by and  based  upon a
     similar financial report or, if permitted, a copy from each sublicensee and
     other commercialization entity(ies).

J.   The  parties  will  promptly  share  all  information  generated  under the
     Co-Development  Program  pursuant  to  the  confidentiality  provisions  of
     Article 21 and with  particular  respect  to the  preclinical  studies  and
     clinical  trials.  Upon  commercialization  of the Product(s),  Eurobiotech
     shall provide SRI with  quarterly  updates  (which may be oral unless other
     requested by SRI) in reasonable  detail,  describing  Eurobiotech's  plans,
     activities and accomplishments.

                                   9. RECORDS

Eurobiotech  shall keep accurate  records of all operations  affecting  payments
hereunder, and shall permit SRI or its duly authorized agent to inspect all such
records and to make  copies of or  extracts  from such  records  during  regular
business hours throughout the term of this Agreement and for a reasonable period
of not less  than  three  (3)  years  thereafter.  The fees  charged  for an SRI
authorized  audit  shall  be paid by SRI;  provided,  however,  that if an audit
discloses an underpayment by Eurobiotech of more than five percent (5%) for such
audited period,  Eurobiotech  shall pay the reasonable fees and expenses charged
by the firm conducting the audit.

                                  10. DILIGENCE

A.   In  conjunction  with  the  developmental   actions  and  commercialization
     activities  of  Eurobiotech  referred to  throughout  this  Agreement,  the
     parties  shall  prepare,  within  90 days of the  date of  signing  of this
     Agreement,  a business development plan outlining the strategy,  timing and
     implementation of steps to commercialize the technology.

B.   Retention of rights by Eurobiotech is contingent  upon  submission of a NDA
     to the FDA within four years of the effective date of this Agreement.

                   11. OWNERSHIP OF THE TECHNOLOGY, TECHNICAL
                          INFORMATION AND IMPROVEMENTS

A.   SRI and  Eurobiotech  shall each retain full  ownership  of their  existing
     intellectual  property  rights  including  rights in the  process  of being
     protected  and rights  conceived  but not yet reduced to practice as of the
     effective date of this Agreement.

B.   All  Improvements  by SRI developed under projects  funded,  in whole or in
     part,  by  Eurobiotech  shall be owned by SRI and shall be  included in the
     licenses  granted  in  this  Agreement.  In the  event  that a  conflicting
     obligation  prevents SRI from including such an Improvement,  SRI shall use
     reasonable  efforts  to  assist  Eurobiotech  to  obtain  rights  from  the
     appropriate third party or parties.

C.   All  Improvements  by SRI made  during  the first  three (3) years from the
     effective date of the Agreement and not developed under projects funded, in
     whole  or in part,  by  Eurobiotech,  shall  be owned by SRI and if  deemed
     reasonably  necessary for Eurobiotech  practice of the Technology,  without
     which such practice would constitute an infringement of SRI's rights, shall
     be  included  to the extent  necessary,  as decided  solely by SRI,  in the
     licenses granted in this Agreement, unless inclusion is not possible due to
     SRI's  obligations  to a  third  party.  In the  event  that a  conflicting
     obligation  prevents SRI from including such an Improvement,  SRI shall use
     reasonable  efforts  to  assist  Eurobiotech  to  obtain  rights  from  the
     appropriate third party or parties.


                                       10

D.   Eurobiotech shall have the first right of negotiation to a license or other
     commercial  arrangement to any SRI  intellectual  property  developed under
     projects  funded,  in whole  or in part,  by  Eurobiotech,  which  does not
     constitute an Improvement.

                             12. PATENT PROSECUTION

A.   SRI shall  file,  prosecute  and  maintain  all of the Patent  that are the
     property of SRI.

B.   Eurobiotech  shall  bear all  patenting  expenses  related  to the  filing,
     prosecution or maintenance of all Patent and Improvement licensed hereunder
     in whole or in part.

C.   SRI shall furnish  Eurobiotech  with copies of all allowed claims when such
     claims  are  allowed in the Field and in the  Territory  for all Patent and
     Improvement licensed hereunder.

D.   SRI shall provide  Eurobiotech with draft copies of all  correspondence and
     filings and related  prosecution  documents  on the Patent and  Improvement
     licensed hereunder and Eurobiotech shall promptly provide comments, if any,
     to SRI. SRI shall confer with Eurobiotech,  and make reasonable  efforts to
     adopt Eurobiotech's suggestions regarding prosecution tactics and strategy.
     Notwithstanding  the  foregoing,  SRI  shall  have the  right to take  such
     actions  as are  reasonably  necessary,  in its good  faith  judgement,  to
     preserve  all  rights  under the  Patent  and  Improvement  throughout  the
     Territory.  As  soon  as  practical,   subsequent  to  the  filing  of  any
     prosecution  document,  SRI shall provide  Eurobiotech  with a copy of such
     document. In addition,  SRI shall copy Eurobiotech with any official office
     action  and SRI  responses  and  submissions.  Eurobiotech  shall  bear the
     expenses of the activities noted in this Article 14.E.

E.   SRI will inform  Eurobiotech at least sixty (60) days prior to any decision
     having  as a result  the  failure  to file,  or the  abandonment  of Patent
     applications  or failure to  maintain a Patent,  Patents  and  Improvements
     licensed  hereunder so that  Eurobiotech  may take over and  maintain  such
     Patent and Improvements in force.

F.   Provided that SRI has been informed by Eurobiotech at least sixty (60) days
     in advance,  in the event that  Eurobiotech  decides  not to pay  patenting
     expenses in any  jurisdiction,  SRI may elect to  maintain  such Patent and
     Improvements in force and terminate  Eurobiotech's  licenses granted as for
     the  jurisdiction  in which  Eurobiotech  abandoned  or  failed  to file or
     maintain such Patent rights.  Notwithstanding  the  foregoing,  Eurobiotech
     shall be obligated to pay patenting expenses within the European Community.

                         13. INFRINGEMENT BY THIRD PARTY

A.   Either party shall notify the other party of any suspected  infringement by
     a third party of the Patent in the Field and the Territory,  and each party
     shall inform the other of any evidence of such infringement(s).


                                       11

<PAGE>


B.   Eurobiotech   shall   have  the   first   right  to   institute   suit  for
     infringement(s)  in the  Field  and  Territory  so long  as this  Agreement
     remains  exclusive.  At Eurobiotech's  expense,  SRI will reasonably assist
     Eurobiotech in such  prosecutions if so requested by Eurobiotech,  and will
     lend its name to such actions if requested  by  Eurobiotech  or required by
     law.  Notwithstanding the foregoing SRI shall have the right to participate
     and be represented in any such  prosecutions  by its own counsel at its own
     expense.

C.   If  SRI  notifies   Eurobiotech   of  its  desire  to  institute  suit  for
     infringement(s)  and Eurobiotech fails to exercise its first right to do so
     within  ninety (90) days of such notice,  then SRI may, at its own expense,
     bring  suit or  take  any  other  appropriate  action.  At  SRI's  expense,
     Eurobiotech will reasonably assist SRI in such prosecutions if so requested
     by SRI,  and will  lend its name to such  actions  if  requested  by SRI or
     required by law.  Notwithstanding the foregoing  Eurobiotech shall have the
     right to participate and be represented in any such prosecutions by its own
     counsel at its own expense.

D.   No settlement of any suspected  infringement(s),  whether or not a suit has
     been instituted, may be entered into without the express written consent of
     Eurobiotech and SRI.

E.   Any amounts  recovered  pursuant to an  infringement  suit,  settlement  or
     otherwise  shall be retained by and be the  property of the party  bringing
     the  action.  In  the  event  Eurobiotech  receives  any  monies  or  other
     consideration  from a third party as a result of Eurobiotech's  exercise of
     its rights under Article 13 of this Agreement,  Eurobiotech  shall first be
     reimbursed  for  expenses  incurred  and paid for, SRI shall then receive a
     portion of the remainder in accordance with the applicable  provision(s) of
     Article 6 as applied  to all such  monies or other  considerations  whether
     such monies or other considerations are denoted as "royalties,"  "damages,"
     "releases" from prior acts, or any other designation.

F.   If  Eurobiotech  fails to exercise  its first right to  institute  suit for
     infringement(s)  and SRI  elects  not to  institute  suit,  then SRI  shall
     provide  Eurobiotech  with at least sixty (60) days notice of its intention
     to terminate Eurobiotech's licenses granted in those jurisdictions affected
     by the  infringement  or to take any  other  action it sees fit in its best
     judgement.

                           14. REVOCATION PROCEEDINGS

A.   In the event either party becomes aware of the institution by a third party
     of  any  proceedings   for  the  revocation  of  any  Patent,   patents  or
     Improvements  in  any  country  in  the  Territory  licensed  hereunder  to
     Eurobiotech, such party shall notify the other party promptly.  Eurobiotech
     shall defend any such proceedings at its own expense, in its own name.

B.   SRI shall have the right to participate in such  revocation  proceedings at
     Eurobiotech's  expense,  and  will  lend its  name to such  proceedings  if
     requested by  Eurobiotech or required by law.  Sublicensees  of Eurobiotech
     shall also have the right to participate in such revocation proceedings.


                                       12

<PAGE>


C.   Settlement of any revocation  proceedings  shall be subject to the approval
     of SRI; such approval shall not be unreasonably withheld.

                     15. INFRINGEMENT OF THIRD PARTY RIGHTS

A.   SRI "does not  warrant"  as stated in  Article  17.  Disclaimer,  "that the
     patents will be free from claims of  infringement  by third  parties or any
     other rights of third parties."

B.   Eurobiotech  as  stipulated  in  Article  18.  Indemnification,  "agrees to
     indemnify,  hold harmless and defend  SRI....  from and against any and all
     demands,  claims,  suits,  and actions ..." which includes  infringement of
     third party rights.

C.   SRI will reasonably assist Eurobiotech to defend or settle such third party
     claim if so requested and at the expense of Eurobiotech.

D.   SRI shall  have the right to  participate  and be  represented  in any such
     claim by a third party by its own counsel.

E.   No  settlement  of any third  party claim may be entered  into  without the
     express written consent of SRI.

F.   In the event,  by way of  counterclaim  or otherwise,  either party or both
     parties  recover  any  damages  or  other  sums  in any  action,  suit,  or
     proceeding  involving a claim by a third party,  or in settlement  thereof,
     such recovery shall be applied and shared as mutually agreed.

                               16. REPRESENTATIONS

A.   This  Agreement is entered  into by SRI in its  corporate  capacity.  It is
     understood  and  agreed  that  the U.S.  Government  is not a party to this
     Agreement  and in no manner  whatsoever  shall be liable  for or assume any
     responsibility or obligation for any claim, cost, or damages arising out of
     or resulting from this Agreement or the subject matter licensed.

B.   Nothing  in this  Agreement  shall  be  deemed  to be a  representation  or
     warranty by SRI, or the U.S. Government, of the safety,  merchantability or
     usefulness  for any purpose,  of any technical  information,  techniques or
     practices at any time made available by SRI to Eurobiotech hereunder.

C.   SRI  represents  that it has the right to grant all of the  rights  herein,

                                  19. INSURANCE

       Eurobiotech shall maintain, during the term of this Agreement, reasonable
amounts  of  comprehensive  general  liability  insurance,   including  products
liability insurance, with reputable and financially secure insurance carriers to
cover the activities of Eurobiotech,  its affiliates and sublicensees hereunder.
Such  insurance  shall  be  written  to  cover  claims   incurred,   discovered,
manifested,  or made  during or beyond the  expiration  or  termination  of this
Agreement during the period that any product,  process, or service, relating to,
or developed  pursuant to, this Agreement is being  commercially  distributed or
sold by Eurobiotech or by a sublicensee, affiliate or agent of Eurobiotech. Such
insurance shall include SRI as an additional insured.  Eurobiotech shall furnish
to SRI a certificate  of insurance  evidencing  such coverage and  periodically,
upon request, provide evidence that the coverage is still in effect.

                            20. TERM AND TERMINATION

A.   This  Agreement  shall  commence on the Effective  Date and,  unless sooner
     terminated  under this  Article  20,  shall  expire  upon the later of: (i)
     expiration  of the last to expire  of all  Patent(s),  Improvement(s),  and
     Patent(s) licensed under this Agreement  [hereafter "Licensed Patents" only
     for  Article  20],  including  any  extensions  thereof  and any periods of
     exclusivity  granted by regulatory  agencies or other governmental  bodies;
     (ii)  Eurobiotech  is no longer due any payments  from  Sublicensee(s);  or
     (iii) Eurobiotech is no longer directly marketing a Product.

B.   The payment  obligations  under the  licenses  granted to  Eurobiotech  for
     Licensed Patents and Technical  Information  shall continue  throughout the
     term as  defined  in  Article  20.A but  would  be  subject  to good  faith
     renegotiations  upon the  expiration  of the last to expire of the Licensed
     Patents,  or upon the abandonment of the last to be abandoned of any patent
     applications if no patents have been issued, whichever is the later, unless
     this Agreement is sooner terminated.  Such good faith  renegotiations shall
     take into  account on a  country-by-country  or  regional  basis but not be
     limited to: (i) Product  competition;  (ii) utilization,  incorporation and
     value of Technical Information;  (iii) value of Technical Information if no
     longer  confidential or proprietary  through no fault of  Eurobiotech,  its
     Sublicensee(s),  contractors,  financiers or any other Eurobiotech agent(s)
     or   purchasers   of  Product  or  services   having  access  to  Technical
     Information;  (iv) the  applicable  contract  or  patent  law or (v)  prior
     payment commitments such as in Article 3.C(2).


                                       15

C.   Eurobiotech  may terminate this Agreement at any time upon ninety (90) days
     written  notice to SRI and upon  payment of all amounts due SRI through the
     effective date of the termination.

D.   Upon  termination of this  Agreement,  neither party shall be released from
     any   obligation   that  matured  prior  to  the  effective  date  of  such
     termination.  Eurobiotech  and any  sublicensee  may,  however,  after  the
     effective date of such termination, sell all Products in inventory provided
     that Eurobiotech shall pay to SRI the royalties and profit-sharing  thereon
     as required by Article 6 hereof and submit the reports  required by Article
     8 hereof.

E.   Except as  provided  in Article  13F  above,  if either  party  shall be in
     default of any  obligation  hereunder,  the other party may terminate  this
     Agreement by giving Notice of Termination  by Certified or Registered  Mail
     to the party at fault,  specifying  the  basis for  termination.  If within
     sixty (60) days after the receipt of such Notice of Termination,  the party
     in default  shall remedy the  condition  forming the basis for  termination
     such Notice of Termination shall cease to be operative,  and this Agreement
     shall continue in full force.

F.   SRI shall have the right to terminate this  Agreement if Eurobiotech  shall
     cease to carry out its business, become bankrupt or insolvent, apply for or
     consent to the  appointment  of a trustee,  receiver or  liquidator  of its
     assets  or  seek  relief  under  any law  for  the  aid of  debtors,  or if
     Eurobiotech fails to submit an NDA as provided in Article 10B.

G.   Eurobiotech shall inform SRI of its intention to file a voluntary  petition
     in bankruptcy or of another's intention to file an involuntary  petition in
     bankruptcy  to be received at least thirty (30) days prior to filing such a
     petition. Eurobiotech's filing without conforming to this requirement shall
     be deemed a  material,  pro-petition  incurable  breach not  subject to the
     Notice requirement of Paragraph 20.

H.   Notwithstanding  anything  else  in this  Agreement  to the  contrary,  the
     parties  agree that  Eurobiotech's  obligation  to pay SRI any  payments or
     other  consideration  accrued but unpaid prior to termination shall survive
     the  termination of this Agreement.  In addition,  Articles 5, 6, 8, 9, 17,
     18,  19, 21,  22, 28 and 34 as well as any other  provisions  to the extent
     required for the full observation and performance of the foregoing Articles
     or which by their nature are intended to survive  such  termination,  shall
     survive the termination of this Agreement and continue to be enforceable.

                   21. CONFIDENTIALITY; PUBLICATION; PUBLICITY

A.   In fulfilling their obligations  under this Agreement,  it may be desirable
     or  necessary  for the parties to disclose to one another  certain of their
     Confidential  Information.  In the event of  receipt  of such  Confidential
     Information,  the receiving  party agrees to preserve such  information  as
     confidential and not to disclose it to third parties or to use it except in
     connection with this


                                       16

<PAGE>


     Agreement  during the term of this  Agreement  and for a period of five (5)
     years following its termination.  The foregoing obligations shall not apply
     to any information that:

     1.   is now in the public  domain or  becomes  generally  available  to the
          public through no fault of the receiving party;

     2.   is already known to, or in the possession  of, the receiving  party as
          can be demonstrated by documentary evidence;

     3.   is disclosed to the receiving  party on a  nonconfidential  basis by a
          third party having the right to make such disclosure; or

     4.   is   independently   developed  by  the  receiving  party  as  can  be
          demonstrated by documentary evidence.

     For the  purposes of the  preceding  portion of this  Section A, Article 21
     only,  "parties"  or "party" but not "third  parties" or "third  party" may
     also include SKI.

     In addition,  to the extent reasonably necessary to fulfill its obligations
     or  exercise  its rights  under  this  Agreement  (i) a party may  disclose
     Confidential  Information  to its  Affiliates,  Sublicensees,  consultants,
     outside contractors and clinical investigators,  on a need-to-know basis on
     condition that such persons or entities agree to be bound by the provisions
     of this  Article 20, (ii) a party or its  Affiliates  or  Sublicensees  may
     disclose  Confidential  Information  to  governmental  or other  regulatory
     authorities to the extent that such  disclosure is reasonably  necessary to
     obtain patents or regulatory authorizations,  provided the disclosing party
     shall  request  confidential  treatment  thereof,  and  (iii) a  party  may
     disclose Confidential Information as required by applicable law, regulation
     or judicial  process,  provided  that such party shall give the other party
     (x) prior written notice thereof, (y) adequate opportunity to object to any
     such disclosure or to request confidential treatment thereof, and (z) shall
     take all steps reasonably possible to minimize the disclosure to that level
     mandated by law.

B.   (i)  If either  party  desires to publish  or  present  the  results of the
          Co-Development Program, the publishing/presenting  party shall provide
          the  non-publishing/non-presenting  party a copy of the  manuscript of
          any      proposed      publication      or      presentation.      The
          non-publishing/non-presenting  party  shall then have thirty (30) days
          to review  and  comment on the  manuscript  or  presentation,  and the
          publishing/presenting   party   agrees  to  delete   any   information
          identified  by the  non-publishing/non-presenting  party as its  Trade
          Secrets or Confidential Information.

     (ii) In the event the non-publishing/non-presenting party determines that a
          Patent  application  covering  information  contained  in the proposed
          publication or presentation  should be filed,  the party proposing the
          publication or presentation shall


                                       17

<PAGE>


          delay such  publication or  presentation  for up to sixty (60) days to
          allow such filing to be made.

C.   Each party  shall  provide the other  party with the prior  opportunity  to
     review and  approve  any press  releases  or similar  public  announcements
     concerning   this   Agreement  or  clinical,   regulatory   and  commercial
     developments  related to Products as soon as  practicable,  but in no event
     later than 24 hours before an announcement is made.  Eurobiotech  shall not
     use the name of SRI or otherwise refer to any organization  related to SRI,
     except  with  the  written  approval  of  SRI,  such  approval  not  to  be
     unreasonably withheld.

                             22. DISPUTE RESOLUTION

A.   The parties shall  attempt to resolve  through good faith  discussions  any
     dispute which arises under this Agreement. Any dispute may, at the election
     of either  party,  be  referred  to the chief  executive  officers,  or the
     equivalent,  of each  party.  If they are  unable to resolve  the  dispute,
     within  thirty (30) days after  delivery  of written  notice of the dispute
     from one  party to the  other,  either  party  may  seek to  resolve  it by
     initiating  Alternative  Dispute  Resolution  ("ADR")  at the  geographical
     location of the noninitiating  party in which the Judicial  Arbitration and
     Mediation Services ("JAMS") of such location,  through a panel of three (3)
     arbitrators (the "Arbitrators"),  shall control the proceedings as provided
     herein.  If JAMS is not in  existence  at the  time  of such  dispute,  the
     American Arbitration Association, of such location shall be substituted.

B.   An ADR shall be initiated by a party by sending  written  notice thereof to
     the  other  party and  JAMS,  which  notice  shall  state the  issues to be
     resolved.  Within ten (10) business days after receipt of such notice,  the
     other  party may, by sending  written  notice to the  initiating  party and
     JAMS, add issues to be resolved. Within twenty (20) business days after the
     date of the  original  ADR  notice,  JAMS shall  nominate to the parties at
     least ten (10) qualified  nominees from JAMS' panel.  Each party shall have
     five (5) business days after the receipt of such  nominations to select one
     Arbitrator.  The two (2)  Arbitrators so selected shall mutually agree on a
     third arbitrator to complete the panel.

C.   Each Arbitrator  shall have experience in the Field relevant to the dispute
     and in intellectual property law matters. In the event of a dispute between
     the parties  relating to the  calculation of any royalties or the amount of
     other  consideration   payable  under  this  Agreement  (including  without
     limitation,  the  results  of any  audit  conducted  on  behalf  of a party
     pursuant to Article 9), then,  in addition to the procedure set forth above
     and in Article 22.B, the  Arbitrators  shall be partners or full members of
     an internationally recognized certified public accounting firm which is not
     an auditing firm for either party and has not provided material services to
     either  party  during the last two (2) year period prior to the date of ADR
     initiation.

D.   Except as  otherwise  provided in this  Article 22, such  hearing  shall be
     conducted pursuant to the JAMS Rules or the Commercial Arbitration Rules of
     the American Arbitration Association (AAA) as applicable.


                                       18

<PAGE>


E.   The  Arbitrators  shall render a  disposition  on the  proposed  rulings as
     expeditiously  as possible  after the  hearing,  but not later than fifteen
     (15)   business  days  after  the   conclusion  of  the  hearing.   In  the
     circumstances where the Arbitrators rule for a party on a claim in the form
     of a claim for  monetary  damages,  the parties will then submit a proposed
     remedy  within ten (10) days of notice of the ruling.  The proposed  remedy
     may be  accompanied  by a brief in support of the remedy not to exceed five
     (5) pages.  The Arbitrators  will rule on the proposed  remedies within ten
     (10) days of their submission.  The Arbitrators' disposition shall be final
     and not appealable, except that either party shall have the right to appeal
     such  disposition  on the  basis it was  affected  by fraud or bad faith in
     connection  with  the  ADR  proceedings.  A  judgment  on the  Arbitrators'
     disposition  may be  entered  in any  court  having  jurisdiction  over the
     parties.  The reasonable fees and expenses of the  Arbitrators,  as well as
     the standard charges of JAMS for its assistance,  shall be borne equally by
     the parties or as they may otherwise agree.

F.   A party shall not be prohibited from bringing a claim for resolution  under
     this Article 22 on the ground that the claim could have been brought during
     an earlier proceeding under this same Article.

G.   The following disputes,  causes of action or claims shall not be subject to
     the dispute resolution process set forth in this Article 22:

     (i)   a claim arising from a suit, action, or proceeding brought by a third
           party or Sublicensee not subject to ADR;

     (ii)  a claim  relating to undisputed  amounts  owed by either party to the
           other under this Agreement;

     (iii) a suit,  action,  or proceeding to compel either party to comply with
           the dispute resolution procedures set forth in this Article 22;

     (iv)  a   dispute,   controversy,  or   claim   relating   to  the   scope,
           enforceability,  infringement or validity of a patent or trademark of
           either party; and

     (v)   a cause of action seeking temporary or preliminary injunction relief.

                                23. ASSIGNABILITY

A.   Eurobiotech   shall  not  assign  any  rights  under  this   Agreement  not
     specifically  transferable  by its terms without  prior written  consent of
     SRI.  SRI may not assign its rights  hereunder  without  the prior  written
     consent of Eurobiotech.

B    In the event of a Change of Control (as defined below) of Eurobiotech,  SRI
     may elect,  upon not less than sixty (60) days written notice following the
     Change of Control or receipt of notice  provided  pursuant to Article 23.C,
     to terminate this Agreement if such Change of Control is not,


                                       19

<PAGE>


     in the good faith judgement of SRI, in the developmental  and/or commercial
     interest  of  the  Licensed   Technology   or   significantly   limits  its
     applicability or scope.

C.   For purposes of this Article  23C,  "Change of Control"  shall be deemed to
     have taken  place if (a) a third  party,  including a "group" as defined in
     section  13(d)(3) of the Securities  Exchange Act of 1934 but excluding the
     current  directors of Eurobiotech,  becomes the beneficial  owner of shares
     having fifty percent (50%) or more of the total number of votes that may be
     cast for the election of directors of Eurobiotech; or (b) as the result of,
     or in connection  with, any cash tender or exchange offer,  merger or other
     business  combination,  sale  of  assets  or  contested  election,  or  any
     combination  of the  foregoing  transactions  (a  "Transaction"),  (X)  the
     persons who were  directors of  Eurobiotech  before the  Transaction  shall
     cease to constitute a majority of the Board of Directors of  Eurobiotech or
     any successor to Eurobiotech,  or (Y) there is the sale,  exchange of other
     disposition of all or substantially all of Eurobiotech's  assets to a third
     party.   Within  thirty  (30)  days   following  a  Change  of  Control  of
     Eurobiotech, Eurobiotech shall provide notice thereof to SRI.

                                   24. REFORM

A.   The parties agree that if any part,  form,  or provision of this  Agreement
     shall be found illegal or in conflict with any valid  controlling  law, the
     validity of the remaining provisions shall not be affected thereby.

B.   In the event the  legality of any  provision  of this  Agreement is brought
     into question because of a decision by a court of competent jurisdiction of
     any country in which this  Agreement  applies,  SRI,  by written  notice to
     Eurobiotech, may revise the provision in question or may delete it entirely
     so as to comply with the decision of the said court.

                            25. WAIVER AND ALTERATION

A.   The failure of either party to insist,  in any one or more instances,  upon
     the  performance  of any of the  terms,  covenants  or  conditions  of this
     Agreement and to exercise any right hereunder,  shall not be construed as a
     waiver  or  relinquishment  of the  future  performance  of any such  term,
     covenant  or  condition  or the  future  exercise  of such  right,  but the
     obligations  of the other  party with  respect to such  future  performance
     shall continue in full force and effect.

B.   A provision of this  Agreement  may be altered only by a writing  signed by
     both parties, except as provided by Article 24, above.

                                   26. MARKING

A.   Eurobiotech  shall  place in a  conspicuous  location on any product or its
     packaging,  which is made or sold  under  any  Patent  coming  within  this
     Agreement,  a patent  notice in  accordance  with the laws  concerning  the
     marking of patented articles.


                                       20

B.   Eurobiotech  shall include a marking provision similar to Paragraph A above
     in every sublicense granted pursuant to Article 7 above.

                               27. IMPLEMENTATION

Each party shall execute any instruments  reasonably believed by the other party
to be necessary to implement the provisions of this Agreement.

                                28. GOVERNING LAW

This  Agreement  shall be deemed to have been entered into and shall be governed
by,  construed and enforced in  accordance  with laws of the State of Alabama of
the United States of America and in the English language, and any action brought
to enforce any provision or obligation  hereunder shall be brought in a court of
competent jurisdiction in the State of Alabama.

                    29. EXPORTATION OF TECHNICAL INFORMATION

Eurobiotech agrees not to export from The United States of America,  directly or
indirectly,  any Technical  Information furnished to Eurobiotech either directly

                                  APPENDIX II


<PAGE>


                Terms for Eurobiotech Group. Inc. ("Eurobiotech")
                  and Southern Research Institute ("Southern").
                            Co-Development Agreement

Scope

     Co-develop  Product(s)  based on  Southern's  patented  and  patent-pending
2`-fluoro-2-halo substituted purine nucleoside technology.

Product(s)

     Drugs effective against  hematologic  malignancies and solid tumors as well
as other therapeutic  indications,  such as (but not exclusively) skin disorders
and transplantation immunity. All modes of administration, particularly oral and
iv., are included in these terms as are specialized  formulations  such as those
imparting controlled-release characteristics.

Agreement

     The parties hereby agree to enter into good faith discussions, based on the
terms agreed to in this document,  for the exclusive  co-development,  exclusive
world-wide  commercial  rights  except  for Japan  and  Southeast  Asia,  to the
Product(s) and all therapeutic  indications and all modes of  administration  of
the 2'-fluoro-2-halo substituted purine nucleoside technology.

Preclinical Development

     Funding  provided by Eurobiotech  not to exceed US$1 million for parenteral
and oral preclinical  toxicology,  oral formulation,  and other preclinical work
needed  prior to  commencing  clinical  trials  including  development  funds to
explore other therapeutic indications.

Drug Synthesis for Preclinical and Phase I

     Discussions for the definitive  Agreement will include the possible role of
Southern in the supply of material and production of GMP and non-GMP Product(s).

Preclinical Toxicology

     To  be  performed  by  Southern  whenever  appropriate  at a  price  to  be
negotiated.  This agreement takes full account of the initial  preparations  for
preclinical toxicology studies conducted and planned by the MD Anderson group.


                                       1

<PAGE>


Phase I

     Funding  provided by Eurobiotech  not to exceed US$1.25 million for Phase I
clinical  trials to be performed at the M. D. Anderson Cancer Center in Houston,
Texas, for hematologic malignancies. Eurobiotech to further fund the preclinical
and, if indicated,  the clinical  development for other therapeutic  indications
including,  but not limited to, solid tumors, skin disorders and transplantation
immunity.

Phase II

     Eurobiotech  to fund the  multi-center  Phase  II  clinical  trials  of the
2'-fluoro-2-halo  substituted purine nucleoside in hematologic  malignancies.  A
decision  to proceed  or not will be made  prior to or at the time when  US$1.25
million has been expended. Eurobiotech's rights to hematologic malignancies will
revert to Southern if the  decision  is not to proceed.  Retention  of rights to
other  therapeutic  indications is contingent upon adequate levels of funding to
be provided by Eurobiotech for fast-track preclinical and clinical development.

NDA After Phase II

     An NDA or  equivalent  document may be submitted to the FDA and/or  foreign
regulatory  agencies  if the  results  after  completion  of Phase II trials are
encouraging and the agencies appear receptive.

Phase Ill

     If Eurobiotech  decides not to proceed after completion of Phase II trials,
the rights to the technology will revert to Southern. If Southern decides not to
proceed with the co-development program (i.e., equal sharing of phase III costs)
after completion of Phase II trials, Eurobiotech shall have the right to conduct
the Phase III trials after paying a non-refundable option fee of $750,000 within
60 days of  completion  and  evaluation  of Phase II  trials or 60 days from the
commencement of Phase III trials,  whichever is the earlier. If Southern decides
to proceed with the co-development  program, if Phase III trials are successful,
and the parties  decide to proceed  with Phase III  clinical  trials,  the costs
incurred will be shared equally between Southern and Eurobiotech.  In that case,
there will be no option fee for commencing Phase III trials.


                                        2

Intellectual Property Ownership

     Southern and Eurobiotech shall each retain full ownership of their existing
intellectual property rights.

Additional Intellectual Property

     Ownership shall be linked directly to inventorship.  Eurobiotech shall have
the first right of negotiation to any additional intellectual property developed
as a result of this co-development program.

Additional Compensation to Southern

     100,000 Shares of common stock of Eurobiotech;  $750,000  milestone payment
on  completion of Phase III trials in Europe or the first sales of Product(s) in
the USA,  whichever is the earlier;  payment of patent costs from the  effective
date of the definitive co-development Agreement for Southern and Sloan Kettering
Institute.

Acquisition of Rights by Third Party (Non-Marketing by Eurobiotech)

     If all or part of the rights granted to Eurobiotech are acquired by a third
party at, or before completion of Phase II clinical trials or prior to Phase III
clinical trials,  all current or future payments derived by Eurobiotech from the
transfer,  whether in cash,  shares,  property  or the like,  including  but not
limited to up-front  payments,  milestone payments and royalties will be divided
equally between Southern and Eurobiotech.

     If Eurobiotech  alone funds Phase III clinical trials,  then if all or part
of the rights are acquired by a third party during or after  completion of Phase
III  trials,  all current or future  payments  derived by  Eurobiotech  from the
transfer,  whether in cash,  shares,  property  or the like,  including  but not
limited to up-front payments and milestone payments but excluding royalties will
be shared on the basis of 65% to  Eurobiotech  and 35% to Southern  until 50% of
the  monies  expended  by  Eurobiotech  in  conducting  the Phase III trials are
reimbursed.  Thereafter,  both  parties  shall  receive 50% each of all payments
derived from the  transfer,  exclusive  of royalty  payments.  Royalty  payments
related  to the  transfer  or  sublicense  of the  rights to  market or  further
sublicense Product(s) shall be divided in the ratio Eurobiotech 65; Southern 35.

     If a third party  funds the Phase III trials  either in whole or in part in
return for  rights,  the parties to this  Agreement  shall  divide all  payments
including  up-front  payments,  milestone payments and royalties from that third
party in equal amounts.

     If the parties to this Agreement share Phase III trial costs equally,  then
if all or part of the rights are  acquired  by a third  party at, or before,  or
after completion of Phase 111 trials, all


                                        3

<PAGE>


payments  derived from the acquisition  will be divided equally between Southern
and Eurobiotech.

     All of the  foregoing  scenarios  are  subject to the  approval of Southern
which shall not be unreasonably withheld.

     As  part  of  the  co-development   program,  should  Eurobiotech  directly
manufacture Product(s) for sale to a third party, Southern and Eurobiotech shall
agree that net income from such sales shall be divided in the ratio  Eurobiotech
65: Southern 35.

Marketing by Eurobiotech

     If products based on the  2'-fluoro-2-halo  substituted  purine nucleosides
are brought to market for the treatment of hematologic malignancies and/or other
therapeutic  indications,  Eurobiotech agrees to use all reasonable  measures to
market the products and to provide a sales force  sufficient to properly support
sales of the Product(s) in designated markets.

     A.   Phase III Funded by Eurobiotech

     Eurobiotech  will pay Southern a 7% royalty  payment on gross sales revenue
on  products  related  to the  2'-fluoro-2-halo  substituted  purine  nucleoside
technology,  applicable in all geographic areas where Eurobiotech is responsible
for the marketing of the Product(s).

     If the gross profit margin from opertions in any geographical  area exceeds
30% a further  profit-sharing  agreement  will  apply,  in addition to the above
royalty payment, according to the following formula:

          Gross Profit Margin           Payment as % of net income*
          -------------------           ---------------------------
                 >70%                              20%
               50-70%                              10%
               31-49%                               5%

*net  income to include  total  revenues  but not  include  local  sales tax and
corporate income taxes.

     If a sublicense is granted to third parties to sell Product(s) in specified
geographical  regions,  Southern  shall  receive  35% of all  current and future
payments  obtained by Eurobiotech  from the third parties  including 35 % of all
royalty payments made by the third parties.

     If  regulatory  approval is obtained  after  completion of Phase II trials,
Eurobiotech shall pay Southern according to the terms of section A above.

     C.   Phase III Trial Cost Reimbursed

     If a third  party  reimburses  the costs of a Phase III  clinical  trial in
exchange for a transfer or sublicense of rights,  Eurobiotech shall pay Southern
for its marketing of Product(s)  based on the terms of section A above,  but all
payments  from such a  sublicensee,  including  up-front,  milestone and royalty
payments shall be divided equally between the parties to this Agreement.

Disposition of Eurobiotech Rights

     Sale or acquisition of Eurobiotech's  rights to this technology in whole or
in part and whether or not in combination with the sale, acquisition,  merger or
disposition  of  Eurobiotech  shall be on the general basis of  Eurobiotech  65:
Southern 35 except as  otherwise  specified in the  Agreement  with the specific
details to be  negotiated  in good faith and subject to the approval of Southern
which shall not be unreasonably withheld.

Payment Duration

     Southern payments continue as long as Eurobiotech's,  subject to good faith
negotiations  regarding the impact of patent expirations,  non-patent countries,
competition, infringement, know-how and other issues.

Foreign Taxes

     Payments to Southern shall be made through  Eurobiotech U.S.A. and will not
include  deductions for foreign taxes (which  not-for-profit  U.S.  corporations
have no means of crediting or offsetting).

Due Diligence

     Upon the definitive  Agreement  being signed the two parties shall prepare,
within 90 days of the date of signing, a business development plan outlining the
strategy,  timing and  implementation  of steps to commercialize the technology.
Retention of rights by Eurobiotech is contingent upon submission of a NDA to the
FDA within four years of the effective date of the definitive Agreement.

for the marketing of the Product(s).

     If the gross profit margin from opertions in any geographical  area exceeds
30% a further  profit-sharing  agreement  will  apply,  in addition to the above
royalty payment, according to the following formula:

          Gross Profit Margin           Payment as % of net income*
          -------------------           ---------------------------
                 >70%                               20%
               50-70%                               10%
               31-49%                                5%

*net  income to include  total  revenues  but not  include  local  sales tax and
corporate income taxes.

     If a sublicense is granted to third parties to sell Product(s) in specified
geographical  regions,  Southern  shall  receive  35% of all  current and future
payments  obtained by Eurobiotech  from the third parties  including 35 % of all
royalty payments made by the third parties.

     B.   Regulatory License Granted After Phase II Clinical Trials

     If  regulatory  approval is obtained  after  completion of Phase II trials,
Eurobiotech shall pay Southern according to the terms of section A above.

     C.   Phase III Trial Cost Reimbursed

     If a third  party  reimburses  the costs of a Phase III  clinical  trial in
exchange for a transfer or sublicense of rights,  Eurobiotech shall pay Southern
for its marketing of Product(s)  based on the terms of section A above,  but all
payments  from such a  sublicensee,  including  up-front,  milestone and royalty
payments shall be divided equally between the parties to this Agreement.

Disposition of Eurobiotech Rights

     Sale or acquisition of Eurobiotech's  rights to this technology in whole or
in part and whether or not in combination with the sale, acquisition,  merger or
disposition  of  Eurobiotech  shall be on the general basis of  Eurobiotech  65:
Southern 35 except as  otherwise  specified in the  Agreement  with the specific
details to be  negotiated  in good faith and subject to the approval of Southern
which shall not be unreasonably withheld.

Payment Duration

     Southern payments continue as long as Eurobiotech's,  subject to good faith
negotiations  regarding the impact of patent expirations,  non-patent countries,
competition, infringement, know-how and other issues.

Foreign Taxes

     Payments to Southern shall be made through  Eurobiotech U.S.A. and will not
include  deductions for foreign taxes (which  not-for-profit  U.S.  corporations
have no means of crediting or offsetting).

ss.5.3    Southern  agrees to  distribute  to SKI it's share of royalty or other
          income in accordance with this  Agreement,  within thirty (30) days of
          receiving such payments.  If  distribution  requires  having shares of
          stock be put  into  SKI's  name,  Southern  agrees  to  initiate  such
          procedure within fifteen (15) days of of receipt of such stock shares.
          Such  payments  shall be  accompanied  by a report from each  licensee
          detailing  the  calculation  of royalties or milestone  payment  being
          paid.  Such payments  shall show "Payment  under Contract SK# 3294" on
          the check stub, and shall be sent to:

          Failure  to pay such sums  within  thirty  (30) days of  receipt  from
          licensee shall be considered a material  breach of this Agreement and,
          after due notice  according to Article 12, is  sufficient  grounds for
          termination of this Agreement with the non-paying Party.

ss.5.4    Southern  shall keep full,  true and accurate  records  containing all
          particulars  that may be  necessary  for the  purpose of  showing  the
          proceeds paid. For the term of this Agreement,  upon receipt of thirty
          (30) days prior written notice, Southern shall allow SKI or its agents
          to  inspect  such  records  for the  purpose of  verifying  Southern's
          payment   statements  or  compliance  in  other   respects  with  this
          Agreement.  Should such  inspection lead to the discovery of a greater
          than five percent (5%)  discrepancy  in reporting to SKI's  detriment,
          Southern agrees to pay the full cost of such inspection.

ss.5.5    Southern agrees to copy SKI promptly with all material  correspondence
          between  Southern and Eurobiotech and to consult with  Sloan-Kettering
          on all Southern  decisions  which may cost an estimated $1000 or more,

          all patent  applications  and patents  relating to Technology shall be
          borne by the respective  Party until the execution of the  Eurobiotech
          Agreement.  Upon signing the Eurobiotech Agreement,  Southern shall be
          responsible for and pay all future costs and expenses  incurred by SKI
          for the preparation, filing, prosecution, issuance, and maintenance of
          the  SKI  Patents.  SKI or its  outside  patent  counsel  will  submit

          pay the  invoiced  amount  within  sixty days (60) of the date of such
          invoice.

ss.6.4    Failure to pay patent  expenses shall be considered a material  breach
          of  contract  and,  after  due  notice  according  to  Article  12, is
          sufficient   grounds  for  termination  of  this  Agreement  with  the
          non-paying Party.

                                    Article 7

ss.7.1    Southern  shall pay to SKI  interest on any amounts not paid when due.
          Such  interest  will  accrue from the  fifteenth  (15th) day after the
          payment  was due at a rate two  percent  (2%)  above the  daily  prime
          interest rate, as determined by The Chase Manhattan Bank (N.A.) or its
          successor  entity,  on each day the  payment  is  delinquent,  and the
          interest  payment  will be due and  payable  on the  first day of each
          month  after  interest  begins to accrue,  until  full  payment of all
          amounts due Sloan-Kettering is made.

ss.7.2    SKI's rights to receive such interest payments shall be in addition to
          any other rights and remedies available to SKI.

ss.7.3    If the interest  rate  required in this  subsection  exceeds the legal
          rate in a  jurisdiction  where a claim  for  such  interest  is  being
          asserted,  the required interest rate shall be reduced, for such claim
          only, to the maximum interest rate allowable in the jurisdiction.

                                    ARTICLE 8
                                 CONFIDENTIALITY

ss.8.1    During  the  term of this  Agreement  and for a period  of five  years
          thereafter, The receiving party (hereinafter "Recipient") shall retain
          in  confidence,  and shall not  disclose to a third party  without the
          express   written  consent  of  the  disclosing   party   (hereinafter
          "Discloser"),   any  Confidential  Information  disclosed  under  this
          Agreement, except for that Confidential Information which:

          a)   was in the  possession or control of the Recipient  before it was
               received, as shown by written records;

          b)   is  available,  or becomes  available,  to the public  through no
               fault of Recipient or of any of Recipient agents or employees;

          c)   is  rightfully  received  from  sources  not  bound by a  similar
               confidentiality agreement

               with the Discloser, or

          d)   is independently  developed by Recipient without knowledge or use
               of the Confidential Information, as proven by competent evidence.

ss.8.2    After   receipt  of  written   consent  from   Discloser  to  disclose
          Confidential   Information  to  a  third  party,  and  prior  to  such
          disclosure,  Recipient  hereto shall  obtain the written  agreement of
          such third party, who is not otherwise bound by fiduciary  obligations
          to Recipient,  to hold in confidence and not make use of  Confidential
          Information  for  any  purpose  other  than  those  permitted  by this
          Agreement. Recipient shall notify the other promptly upon discovery of
          any  unauthorized  use or disclosure of the  Discloser's  Confidential
          Information.

ss.8.3    Nothing in this  Agreement  shall preclude SKI or Southern from making
          reports or disclosures  required by the National  Institutes of Health
          or any other  organization  which provided funds used for the research
          relating to Technology,  or disclosing Confidential Information to the
          minimum  extent  required to comply with court orders,  regulations or
          statutes.

                                    ARTICLE 9
                               PATENT INFRINGEMENT

ss.9.1    If any Party becomes aware of any  infringement of a patent covered by
          this Agreement,  it shall notify and discuss with the other Party what
          action is required to terminate  such  infringement.  Each Party shall
          have the option of taking action against any third party  infringer of
          their respective  patent rights.  If both Parties agree to act against
          the infringement jointly, they shall share equally in the expenses and
          disbursements  in  connection  with such  action  and shall also share
          equally all monies  received as a result of such action.  If one Party
          does not agree to join in the action against  infringement,  the other
          Party will have the right to prosecute a patent infringement action at
          their  sole  expense,  and  shall be  entitled  to retain  all  monies
          recovered.

ss.9.2    If the Eurobiotech Agreement has been executed at the time the Parties
          become aware of any such  infringement,  Eurobiotech  may join in such
          action  against  any  third  party   infringer  as  specified  in  the
          Eurobiotech Agreement. In that event one or both Parties may elect not
          to join in the action  against the third party  infringer as specified
          in the  Eurobiotech  Agreement  without being  penalized  according to
          Article 9.1.

ss.12.2   Failure by any Party to comply  with any of the  material  obligations
          and  conditions  contained in this  Agreement  shall entitle the other
          Party to give written  notice  requiring it to cure such  default.  If
          such default is not cured within sixty (60) days after receipt of such
          notice,  the notifying Party shall be entitled  (without  prejudice to
          any  of  its  other  rights  conferred  on it by  this  Agreement)  to
          terminate this Agreement with the defaulting Party by giving notice to
