ITEM 1.  BUSINESS


     UroGen Corp. is a biopharmaceutical company dedicated to the development of
innovative gene therapy products utilizing advanced adenoviral vector
technologies for the treatment of hemophilia, cancer and other genetic
disorders. In July 1998, UroGen acquired certain equipment from the gene therapy
unit of Baxter Healthcare Corporation together with exclusive rights to certain
technologies in exchange for 1,841,217 shares of Common Stock and 5,830 shares
of Series A Preferred Stock (See "Certain Relationships and Related Transactions
Baxter Agreements"). Prior to the acquisition, UroGen was a biotechnology
company developing products for the diagnosis and therapy of prostate cancer.
The technology acquired from Baxter is based upon recombinant adenoviral vector
systems that we believe provide superior gene transfer efficiency and expression
compared to other gene therapy approaches. The proprietary gene transfer vectors
have been engineered to contain less than 3% of the native adenovirus. UroGen
believes that removal of unwanted adenoviral viral genes permits increased gene
transfer capacity with high level, sustained gene expression and improved safety
compared to standard vector systems. As these recombinant viruses are engineered
to minimize the presence of adenoviral gene sequences, they are termed "Mini-Ad"
vectors. These Mini-Ad vectors retain the broad range of cellular infectivity
and efficient gene transfer characteristics of native adenoviruses. Importantly,
we believe we have engineered capabilities into our mini-Ad systems which
provide for sustained, high level gene expression. We believe our proprietary
gene transfer and expression systems advance the capabilities of gene therapy
for disease management, providing what we believe to be efficient gene transfer
and long term gene expression desired for clinical applications.

     The initial focus of our research and development efforts will be the
generation of products for the treatment of hemophilia and prostate cancer. Two
vector products are under development: 1) Factor VIII Mini-Ad Vector for the
treatment of hemophilia; and 2) Complementary Oncolytic Interleukin-3 (IL-3)
Adenoviral Vectors which result in tumor specific cell lysis, radiation
sensitization and anti-tumor immune responses for the treatment of prostate
cancer. The Factor VIII Mini-Ad Vector for hemophilia is expected to provide a
greater duration of active Factor VIII function, preventing chronic bleeding and
joint damage which are characteristic of this disorder. The complementary
oncolytic IL-3 Adenoviral Vectors are comprised of a mixture of two adenoviral
vectors which complement each other resulting in viral replication and
propagation restricted to tumor tissues leading to specific tumor cell lysis,
radiation sensitization and anti-tumor immune responses for the treatment of
prostate cancer.

     UroGen was incorporated in Delaware in June 1995 as a wholly-owned
subsidiary of Medstone International, Inc., a Delaware Company. UroGen was
formed from the medical biology and small molecule pharmaceuticals divisions of
Medstone. The business of UroGen operated as two divisions of Medstone from July
1, 1991 to December 29, 1995. On February 9, 1996, Medstone distributed all of
the outstanding stock of UroGen Corp. to its shareholders by issuing a dividend
of one share of UroGen Common Stock for each share of Medstone stock held as of
December 29, 1995. Our principal executive offices are located at 10835 Altman
Row, Suite 150, San Diego, California 92121, and our telephone number is (619)
450-5949. References in this Prospectus to "we", "us", "UroGen" or "the Company"
refer to UroGen Corp., a Delaware corporation.

RESEARCH AND DEVELOPMENT


THE MINI-AD SYSTEM
- ------------------

      The components of the Mini-Ad system are diagrammed in Figure 1. The Mini-
Viral Plasmid contains the therapeutic transgene and promoter sequences which
permit sustained transgene expression in host cells. The Ad Helper Cell Line and
Helper Virus, respectively, provide the early E1A and other adenoviral genes
required to package the Mini-Ad Vector into viral particles which contain the
outer coat and core proteins of native adenoviruses. These proteins mediate the
broad host range and efficient gene transfer characteristics of native
adenoviruses. However, the genes encoding these proteins are not packaged into
the Mini-Ad Vector, which is replication incompetent and contains less than 3%
adenoviral components. The Mini-Ad Vector product is readily purified from the
Ad Helper Cell Line and processed for distribution in an injectable preparation.

FIGURE 1 -- DIAGRAM OF COMPONENTS OF THE MINI-AD SYSTEM

FACTOR VIII MINI-AD VECTOR FOR HEMOPHILIA A/LIVER DIRECTED GENE THERAPY
- -----------------------------------------------------------------------

     The ease of delivery and affinity of adenoviruses for the liver makes this
organ a logical target for this gene delivery system. Intravenous injection of
adenoviruses results in greater than 90% of viral infection in hepatocytes. The
first Mini-Ad product under development is a Factor VIII vector for the
treatment of hemophilia A. As the liver is one of the major organs for natural
Factor VIII production, the vector has been engineered to optimize Factor VIII
expression in this organ. The vector uses a tissue-specific promoter to drive
Factor VIII cDNA expression for sustained high-level expression and secretion of
the protein. In mouse hemophilia models, intravenous injection of this mini-Ad
vector resulted in serum Factor VIII concentrations that are twenty to thirty
times therapeutic levels (Figure 2). These serum levels have been maintained for
a duration of up to one year with correction of bleeding time. The animals
continue to be followed to evaluate the duration of therapeutic Factor VIII
expression.

FIGURE 2 -- CHART SHOWING EXPRESSION OF FACTOR VIII IN MINI AD-INJECTED MICE FOR
DAYS AFTER INJECTION

     We believe that there may be additional product opportunities for this
liver directed vector technology. Diseases resulting from abnormal function or
biochemistry of the liver are among the leading causes of morbidity and
mortality. Cardiovascular disease, the leading cause of death in the
industrialized world, is causally linked to hyperlipidemia, which is controlled
by genes expressed in the liver. There are several common genetic liver diseases
for which effective gene therapy to replace aberrantly functioning genes would
supplant current conventional therapies, which are either cumbersome or
ineffective. We believe that among them, familial hypercholesterolemia, due to
deficiency of LDL-receptors in the liver, is one of the additional diseases
suitable for Mini-Ad therapy.

ONCOLYTIC IL-3 VIRAL VECTOR FOR PROSTATE CANCER
- -------------------------------------------------------

     Prostatic carcinoma is the most common cancer among men. It currently
occurs in approximately one in six men and has an annual incidence of in the
United States 187,000 new cases. We believe that a significant advantage of our
proprietary oncolytic IL-3 viral vector product may be its ability to have both
local and systemic anti-tumor activity, while sensitizing tumors to the effects
of standard cancer therapies. These multiple modes of action may have benefits
in the treatment of prostate cancer and other neoplasms. Successful treatment of
prostate cancer requires complete eradication of tumors within the prostate and
the elimination of metastatic tumor cells, which have migrated from the prostate
in approximately fifty percent of patients at the time of diagnosis. Our
proprietary viral oncolytic IL-3 viral vector has intrinsic viral anti-tumor
lytic activity. In addition, we believe the product will result in IL-3
expression, which sensitizes tumors to the effects of radiation, providing
improved treatment of disease within the prostate, and simultaneously inducing
anti-tumor immunity capable of destroying
                                       
                                       4

metastatic lesions. Our first oncolytic IL-3 viral vector product will be 
injected intratumorly and administered with radiation for the treatment of 
prostate cancer (Figure 3).

FIGURE 3 -- DIAGRAM OF THE MULTIPLE EFFECT OF ONCOLYTIC MINI-AD IL-3 AND 
            RADIOSENSITIZATION

     The oncolytic IL-3 viral vector product is comprised of a mixture of two 
adenoviral vectors that complement each other to permit selective adenoviral 
replication and tumor cell lysis limited to cancer tissues. In this system, one 
vector contains the AdEl gene under the control of a tumor tissue specific
promoter (the controlled vector), and the second vector contains the remainder
of the adenoviral genome without AdEl (the supplemental vector) (Figure 4). The
viruses complement each other resulting in viral replication and propagation
restricted to tumor tissues leading to specific tumor cell lysis. Importantly,
we believe the controlled vector can be engineered to carry and express
additional therapeutic genes such as IL-3.

FIGURE 4 -- DIAGRAM OF THE ONCOLYTIC DUAL-AD SYSTEM

     Preliminary studies with vectors incorporating a prostate specific antigen
(PSA) promoter have cured prostate tumors in animal models following
intratumoral injection (Figure 5). 

FIGURE 5 -- CHART SHOWING THE ONCOLYTIC EFFECT OF PROSTATE-SPECIFIC DUAL-AD IN 
            MICE FOR DAYS AFTER INJECTION

     Unlike other oncolytic viral systems, which have limited capacity for
delivering additional therapeutic genes, we believe our vectors may be
engineered to express genes encoding cytokines and co-stimulatory factors that
can enhance tumor antigen presentation and T-cell activation to induce systemic
anti-tumor immunity. We have demonstrated that IL-3 gene therapy sensitizes
tumors to the effects of radiation and stimulates anti-tumor immune responses
capable of eradicating metastatic disease. IL-3 stimulates antigen presenting
cells (macrophages and dendritic cells) required for the generation of systemic
anti-tumor immunity. In animal tumor models, the combination of IL-3 cytokine
gene therapy with radiotherapy was synergistic resulting in enhanced efficacy of
local radiotherapy and generating systemic anti-tumor immunity. We used IL-3-
transfected murine fibrosarcoma Fsa tumors as a model in these studies. The IL-3
secreting tumors (Fsa-JmIL3) were more sensitive than parental tumors (Fsa) to
irradiation in vivo (Figure 6) and post-radiotherapy developed a dramatic T cell
infiltrate and induced a high level of systemic immunity. In this study, 25 Gy
of radiation caused parental Fsa tumors to regress only temporarily and then
began progressing again after 10 days. In contrast, IL-3 transduced Fsa-JmIL3
tumors continued to regress after irradiation and complete tumor remission was
achieved (Figure 6). These cured mice developed long lasting systemic immunity
to parental tumor and were resistant to subcutaneous challenge with 500,000
parental Fsa tumor cells three months later in five out of five animals tested.
This dose of tumor cells reproducibly caused subcutaneous tumors in one hundred
percent of non-immunized animals.

FIGURE 6 -- CHART SHOWING THE EFFECT OF THE IL-3 GENE INJECTED IN-VIVO COUPLED 
            WITH RADIOSENSITIZATION TREATMENT

     We believe our multimodality oncolytic, radiation sensitizing,
immunotherapeutic approach is suited for the treatment of prostate cancer which
requires elimination of tumors both within the prostate and at metastatic sites.
Current surgical and radiation treatments are incapable of eradicating
metastatic disease.

     Approximately 71% of UroGen's employees are engaged in research and
development. During the years ended December 31, 1998, 1997 and 1996, we spent
approximately $1,915,548 (before the non-cash write-off of acquired in-process

                                       5
<PAGE>
 
technology), $346,000 and $348,000, respectively, for research and development.

MANUFACTURING

     We intend to utilize contract manufacturers for most of the preclinical and
clinical requirements for our potential products. This strategy is designed to
(i) accelerate the scale-up of manufacturing processes to commercial scale (ii)
reduce initial capital investment (iii) result in competitive manufacturing
costs and (iv) provide access to a wide range of manufacturing technologies. The
Company is in the process of investigating contract manufacturing alternatives.

PATENTS AND LICENSES

     We believe that patent and trade secret protection is important to our
business and that our future will depend in part on our ability to maintain our
technology licenses, protect our trade secrets, secure additional patents and
operate without infringing the proprietary rights of others. UroGen currently
holds exclusive rights to one issued United States patent, one allowed United
States patent application and several other pending patent applications that
relate to genetic therapies and molecular diagnostics.

     A series of United States and foreign patent applications for the Mini-Ad
and Oncolytic Vector systems have been filed. These applications cover all
fields of use for the packaging attenuated helper Ads, various mini-Ad vectors,
and related helper cell lines. The novel targeted gene integration mechanism
which permits sustained, high level gene expression has also been claimed in
these patent applications. We have obtained exclusive world-wide rights to a
patent application covering the use of cytokines and immunomodulatory substances
utilized in combination with radiation for enhancing the effects of radiation
and stimulating anti-tumor immunity in the treatment of certain cancers. We have
also filed a patent application for the oncolytic/immunogenic complimentary-Ad
vector system utilizing tumor or tissue specific promoters to specifically
induce tumor lysis and systemic anti-tumor immunity to destroy both localized
and disseminated tumors.

     The pharmaceutical and biotechnology fields are characterized by a large
number of patent filings. A substantial number of patents have already been
issued to other pharmaceutical and biotechnology companies. Research has been
conducted for many years in the gene therapy field by pharmaceutical and
biotechnology companies and other organizations. Competitors may have filed
applications for or have been issued patents and may obtain additional patents
and proprietary rights related to products or processes competitive with or
similar to ours. Patents applications are maintained in secrecy for a period
after filing. Publication of discoveries in the scientific or patent literature
tends to lag behind actual discoveries and the filing of related patent
applications. We may not be aware of all of the patents potentially adverse to
UroGen's interest that may have been issued to other companies, research or
academic institutions, or others. No assurances can be given that such patents
which contain claims relating to UroGen's technology.

                                       6
<PAGE>
 
      To date, no consistent policy has emerged regarding the breadth of claims
allowed in pharmaceutical and biotechnology patents. If patents have been or are
issued to others containing preclusive or conflicting claims, and such claims
are ultimately determined to be valid, we may be required to obtain licenses to
one or more of such patents or to develop or obtain alternative technology. We
believe that our current and proposed activities do not infringe on any patents
that would be determined to be valid. We can not assure you that patents do not
exist in the United States or in other countries or that patents will not be
issued to third parties that contain preclusive or conflicting claims with
respect to any of UroGen's technologies. Commercialization of UroGen's proposed
products may require licensing and/or cross-licensing of one or more patents
with other organizations in the field. We can not assure you that the licenses
that might be required for UroGen's processes or products would be available on
commercially acceptable terms, if at all.

     UroGen's breach of an existing license or failure to obtain a license to
technology required to commercialize its product candidates may have a material
adverse effect on our business, financial condition and results of operations.
Litigation, which could result in substantial cost, may also be necessary to
enforce any patents issued to UroGen or to determine the scope and validity of
third-party proprietary rights. If our competitors prepare and file patent
applications in the United States that claim technology also claimed by us, we
may have to participate in interference proceedings declared by the United
Stated Patent and Trademark Office to determine the priority of invention, which
could result in substantial cost, even if the eventual outcome is favorable to
us. An adverse outcome could subject UroGen to significant liabilities to third
parties and require us to license disputed rights from third parties or to cease
using such technology.

     UroGen also relies on trade secrets to protect our technology, especially
where patent protection is not believed to be appropriate or obtainable. We
protect our proprietary technology and processes, in part, by confidentiality
agreements with our employees, consultants and collaborators. We can not assure
you that these agreements will not be breached, that we would have adequate
remedies for any breach, or that UroGen's trade secrets or those of its
collaborators or contractors will not otherwise become known or be discovered
independently by competitors.

     Patents issued and patent applications filed internationally relating to
gene therapy are numerous and we cannot assure you that current and potential
competitors or other third parties have not filed or received will not file or
receive applications in the future for, patents or obtain additional proprietary
rights relating to products or processes used or proposed to be used by UroGen.
Additionally, there is certain subject matter which is patentable in the United
States but not generally patentable outside of the United States. Differences in
what constitutes patentable subject matter in various countries may limit the
protection we can obtain on some of our inventions outside of the United States.
For example, methods of treating humans are not patentable in many countries
outside of the United States. These and-or other issues may prevent UroGen from
obtaining patent protection outside of the United States which would have a
material adverse effect on our business, financial condition and results of
operations.

COMPETITION

     The pharmaceutical and biotechnology industries are intensely competitive.
Any product candidate developed by UroGen would compete with existing drugs and
therapies and with others under development. There are many pharmaceutical
companies, biotechnology companies, public and private universities and research
organizations actively engaged in research and development of products for the
treatment of hemophilia

                                       7
<PAGE>
 
and prostate cancer. Many of these organizations have financial, technical,
manufacturing and marketing resources which are greater than ours. If a
competing company develops or acquires rights to a more efficient, more
effective, or safer competitive therapy for treatment of the same diseases we
have targeted, or one which offers significantly lower costs of treatment, our
business, financial condition and results of operations could be materially
adversely affected.

     We believe that our product development programs will be subject to
significant competition from companies using alternative technologies, as well
as to increasing competition from companies that develop and apply technologies
similar to our technologies. Other companies may succeed in developing products
earlier than we do, obtaining approvals for such products from the FDA more
rapidly than we do or developing products that are safer and more effective than
those under development or proposed to be developed by us. We can not assure you
that research and development by others will not render our technology or
potential products obsolete or non-competitive or result in treatments superior
to any therapy developed by us, or that any therapy developed by UroGen will be
preferred to any existing or newly developed technologies.

EMPLOYEES

     At December 31, 1998 UroGen had 14 employees, including 10 in research and
development and 4 in finance and administration. Our continued success will
depend in large measure on our ability to attract and retain highly skilled
employees who are in great demand. None of our employees are represented by a
labor union and we believe that our relations with the employees are generally
good.

                                       8

ITEM 2.  PROPERTIES

         UroGen leases approximately 4,800 square feet of office and laboratory
space in San Diego, California. The term of the lease expires in May 2000. We
believe our existing facilities will be sufficient to meet our anticipated
operating needs through May 2000.
 
ITEM 3.  LEGAL PROCEEDINGS

  UroGen is not a party to any material litigation or legal proceedings.

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

  None.

ITEM 7.  Management's Discussion and Analysis of Financial
         Condition and Results of Operations

     This Management's Discussion and Analysis of Financial Condition and
Results of Operations contains forward-looking statements that involve risks and
uncertainties. The statements that are not purely historical are forward-looking
statements within the meaning of Section 27A of the Securities Act of 1933 and
Section 21E of the Securities Exchange Act of 1934, including without limitation
statements regarding the Company's expectations, beliefs, intentions or
strategies regarding the future. All forward-looking statements included in this
document are based on information available to the Company on the date hereof,
and the Company assumes no obligation to update any such forward-looking
statements. The Company's actual results could differ materially from those
anticipated in these forward-looking statements.

OVERVIEW

     UroGen commenced operations as a stand-alone entity in January 1996 to
develop pharmaceuticals to treat diseases in urology, with a particular interest
in prostate cancer. On July 8, 1998, UroGen entered into an agreement with
Baxter Healthcare Corporation in which we acquired the exclusive rights to
certain gene therapy technologies and certain tangible assets in exchange for
1,841,219 shares of Common Stock and 5,830 shares of Series A Preferred Stock
(See "Certain Relationships and Related Transactions-Baxter Agreements").

     UroGen has been in the development stage since inception, with its current
activities consisting of the development of its core technology, which is based
upon novel recombinant adenoviral vector systems, that we believe provide
superior gene transfer efficiency and expression compared to other gene therapy
approaches. We expect to incur increasing research and development expenditures
as we focus our efforts on further development of its Factor VIII Mini-Ad
Vector for Hemophilia and Complementary Oncolytic IL-3 Viral Vector Product.
Accordingly, we expect no significant revenues and to incur significant
operating losses over the next several years.

RESULTS OF OPERATIONS

Revenues

     UroGen has generated revenues to date of $791,000 from contract research
agreements and grants and $50,000 from the sale of proprietary biological
materials. Total revenues for the years ended December 31, 1998, 1997 and 1996
were $192,000, $194,000, and none, respectively. We anticipate seeking
additional research agreements and grants to help fund research and development
efforts; however, we do not expect that contract research will result in
significant revenues in the future. We do not anticipate revenues from products
for at least four years.

Research and development and acquired in-process technology

     Research and development expenses and acquired in-process technology
charges during the years ended December 31, 1996, 1997 and 1998 were $348,000,
$346,000 and $7,371,053, respectively. Research and development expenses during
1996, 1997 and through June 30, 1998 consisted primarily of payments to
consultants who were performing research and to fees related to technology
licenses and patent applications. Following consummation of the Baxter
transaction on July 8, 1998, research and development costs were expanded to
include the costs of the hemophilia and cancer programs acquired from Baxter,
but which were continued at Baxter until the employees and tangible assets
involved were moved to our facilities in October 1998. Additionally, the
technology acquired from Baxter valued at $5,455,505 was charged to acquired in-
process technology due to the early stage of development. We anticipate
increasing research and development expenditures in the future as we conduct

                                       12
<PAGE>
 
preclinical and clinical testing necessary to bring our products to market and
to establish manufacturing and marketing capabilities.

General and administrative expenses

     General and administrative expenses during the years ended December 31,
1996, 1997 and 1998 were $174,000, $151,000 and $488,000, respectively. General
and administrative expenses include the costs of our administrative personnel
and consultants, office lease expenses and other overhead costs, including legal
and accounting costs. General and administrative expenses have increased related
to the increased level of operations, and we expect general and administrative
expenses to continue to increase to support our increasing research and
development activities.

LIQUIDITY AND CAPITAL RESOURCES

     Net cash used by operating activities was $642,511 during the year ended
December 31, 1998. Net cash used by operating activities consists primarily of
UroGen's net loss increased by non-cash expenses, such as the write-off of in-
process technology acquired with stock and expenses paid via advances from
Baxter. Net cash used by investing activities of $63,493 during 1998 consists of
the purchase of furniture and equipment. Net cash provided by financing
activities of $946,634 during 1998 consists of proceeds from notes payable of
$1,030,000 offset by expenses paid to raise capital.

     Medstone funded all of UroGen's operations from July 1, 1991 (inception)
through and ending with a $500,000 capital contribution of cash on February 9,
1996. In July 1998, we completed an offering of 8% Convertible Subordinated
Notes due June 30, 1999, which raised $1,030,000. UroGen has incurred net losses
of $12,431,356 since its inception and has never been profitable during its
existence. We expect to incur significant additional operating losses over the
next several years as our research and development efforts expand. Our ability
to achieve profitability depends upon our ability, alone or with others, to
successfully complete development of products, obtain required regulatory
approvals and manufacture and market products. We can not assure you that we
will be successful or that we will attain significant revenues or
profitability. Our operations to date have consumed substantial amounts of
cash. The negative cash flow from operations is expected to continue and to
accelerate in the foreseeable future. The development of our products will
require a commitment of substantial funds to conduct the costly and time-
consuming research, preclinical and clinical testing necessary to bring our
products to market and to establish manufacturing and marketing capabilities.
UroGen's future capital requirements will depend on many factors, including
scientific progress in our research and development programs, our ability to
establish collaborative arrangements with others for drug development, progress
with preclinical and clinical trials, the time and costs involved in obtaining
regulatory approvals and effective commercialization activities.

   Under the terms of our Developmental Collaboration Agreement and Credit
Agreements with Baxter (See "Certain Relationships and Related Transactions
Baxter Transactions"), Baxter is required to provide funding for development of
the hemophilia product until we commence a Phase I Clinical Trial for the
hemophilia product. The funding provided by Baxter is in the form of a note
payable which can be converted to Series B Preferred Stock at our option on
December 31 of each year of the agreement.

     We have commitments for additional capital through the sale of convertible
notes and warrants. We anticipate that this additional capital, coupled with
existing capital resources, including funds received from Baxter under the
Developmental Collaboration Agreement, will enable us to maintain our current
and planned operations through November 1999. Accordingly, we will need to raise
substantial additional capital to fund our operations. We intend to seek such
additional funding either through collaborative arrangements or through public
or private equity or debt financings. Additional financing may not be available
on acceptable terms or at all. If adequate funds are not available, we may be
required to delay or reduce the scope of our operations or to obtain funds
through arrangements with collaborative partners or others that may require us
to relinquish rights we may have.
                                      13

     Our independent auditors have issued their report on our financial
statements. This report contains an explanatory paragraph which expresses
substantial doubt regarding UroGen's ability to continue as a going concern
based on certain existing conditions. Successful completion of our development
program and transition, ultimately, to attaining profitable operations is
dependent upon obtaining additional financing adequate to fulfill our research
and development activities, and achieving a level of revenues adequate to
support our cost structure.

TECHNOLOGY LICENSES

UroGen entered into a license agreement with The Immune Response Corporation in
March 1997 which was amended in January 1999. Under the IRC License, UroGen is
obligated to make a milestone payment to IRC of $200,000 upon the approval by
the Food and Drug Administration or the governing health authority of any other
country of its first product related to the licensed technology. This fee can be
offset against future royalty payments. UroGen is obligated to pay royalties on
its net sales revenue and a percentage of all revenues received from sublicenses
relating to the tumor radiosensitization gene therapy technology. Additionally,
UroGen agreed in the January 1999 amendment to reimburse IRC for past patent
expenses relating to the licensed technology in the amount of $59,400 payable
during 1999.

In November 1997, UroGen entered into a license agreement with an individual and
an affiliated research organization under which we obtained an exclusive right
to certain technology for commercial purposes. UroGen is obligated to pay
royalties on its net sales revenues and a percentage of revenues from
sublicenses relating the technology (the "Running Royalties"). Additionally,
UroGen is required to make minimum annual royalties of $30,000 for the duration
of the agreement. The minimum annual royalties may be credited against Running
Royalties, as defined, for that year. If there are no Running Royalties to
offset the annual royalty, one-half of the annual royalty may be carried forward
to offset Running Royalties from the following year. Within thirty days of
UroGen entering into an agreement with a corporate partner or strategic alliance
relationship related to this technology, UroGen will pay a minimum of $12,500
per month to fund additional research.

In September 1996, UroGen entered into a license agreement with the Regents of
the University of California to license rights to certain patents and continuing
applications thereof in the field of diagnosis of metastases by nucleic acid
amplification. We are required to pay an annual license maintenance fee of
$10,000 until we are selling licensed product. We are also required to pay
milestone fees of $25,000 upon filing an Initial New Drug Application on a
licensed product or method with the Food and Drug Administration and $50,000
upon marketing approval of a licensed product or method by the FDA. UroGen will
pay royalties on its net sales revenues of licensed products or methods. A
minimum annual royalty of $50,000 is payable beginning with the year of first
commercial sale of licensed product, but no later than the fifth year of the
agreement. The minimum annual royalty will be credited against earned royalty
due for the year in which the annual minimum payment was made.

YEAR 2000 COMPLIANCE 

     The Year 2000 issue refers to the inability of a date-sensitive computer
program to recognize a two-digit date field designated as "00" as the year 2000.
Mistaking "00" for 1900 could result in a system failure or miscalculations
causing disruptions to operations, an inability to process transactions or an
inability to engage in other normal business activities. This is a significant
issue for most companies with far-reaching implications, some of which cannot be
anticipated or predicted with any degree of certainty.

     We are in the process of addressing the Year 2000 issue. The majority of
our systems are either new or have been recently upgraded with upgrades
including Year 2000 compliance. Such upgrades have cost approximately $1,500 to
date. We do not engage in significant electronic interfaces with third parties.
However, failure on the part of third parties we do business with to be Year
2000 compliant could impact their operations which would, in turn, impact our
operations. The most reasonably likely worse case scenario resulting from the
Year 2000 issue is unproductive operations. We will have a contingency plan in
place for Year 2000 issues by September 1999.

     We anticipate that the amount we will spend to modify or replace software
in order to remediate the Year 2000 issue should not have a material effect on
UroGen's liquidity or results of operations. Additionally, those costs are not
expected to cause reported financial information not to be indicative of future
operating results or future financial condition.

ITEM 7A  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     At December 31, 1998, the Company's cash and cash equivalents were invested
in liquid checking and money market accounts, and will not change in value if 
interest rates change. Accordingly, an immediate 10% change in interest rates 
would not have an impact on our financial condition or results of operations. 

     The Company does not conduct business with foreign entities, and does not 
have any foreign exchange risk.

SCIENTIFIC ADVISORY BOARD

     UroGen plans to establish a Scientific Advisory Board to give guidance to
our scientific and technology strategies. The members of the Scientific Advisory
Board will advise and consult with our management on an informal basis from time
to time on scientific and technology strategies of the technical matters in
their respective areas of expertise. Members of the Scientific Advisory Board
may perform consulting services for UroGen, for which they may receive cash or
other compensation.

COMPENSATION OF DIRECTORS

     Cash Compensation

          UroGen does not compensate its Directors for their services as such.
However, Directors are reimbursed for their out-of-pocket expenses in attending
Board meetings.

     1995 Directors' Option Plan

          Non-employee directors also receive stock options under the Company's
1995 Directors' Option Plan (the "Directors' Plan"). The Directors' Plan was
adopted and approved by the shareholders of the Company in 1995 to provide
automatic, nondiscretionary grants of options to non-employee directors of the
Company. A total of 100,000 shares of Common Stock have been reserved for
issuance under the Directors' Plan. The Directors' Plan provides that each non-
employee director is automatically granted an option to purchase 10,000 shares
of UroGen Corp. Common Stock upon his or her initial election or appointment as
an non-employee director (Initial Options). Subsequently, each non-employee
director who has served for at least six months will be granted an additional
option to purchase 5,000 shares of UroGen Corp. Common Stock on December 31 or
each year so long as he or she remains an non-employee director (Subsequent
Options). The exercise price of the options granted to non-employee directors
must be the fair market value of UroGen Common Stock on the date of grant.
Options granted to non-employee directors have ten-year terms, subject to an 
non-employee director's continued service as a director. Initial Options vest
over

                                      18

three years rate of 33.3% per year, subsequent options vest one year from the
grant date. As of December 31, 1998, options to purchase 35,000 shares of Common
Stock to non-employee directors has been granted under the Directors' Plan.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

BAXTER AGREEMENTS
- -----------------

In July 1998, UroGen executed various agreements with Baxter Healthcare
Corporation pursuant to which we acquired certain rights and assets from Baxter.
Under the terms of the agreements, UroGen obtained the rights to Baxter's
adenoviral-based gene transfer technologies and certain equipment in exchange
for 5,830 shares of non-voting convertible Series A Preferred Stock and
1,841,219 shares of Common Stock. The shares issued to acquire the gene transfer
technologies were valued at $5,455,505 based on the fair value of the stock on
the date of issuance and was charged to acquired in-process technology due to
the early stage of development of such technology. The value of the stock issued
for fixed assets was $343,937 based upon the fair value of those assets.

Baxter will provide funding to UroGen for continued research and development of
this technology as it relates to the treatment of hemophilia under the
Developmental Collaboration Agreement. Baxter will provide such funding through
the date on which the treatment of the first patient in a Phase I clinical trial
begins. This development funding is provided under a Credit Agreement. The
balance outstanding under the Credit Agreement as of December 31, 1998 was
$1,044,275. Under the terms of the Credit Agreement, the amounts outstanding
under the Credit Agreement are due and payable on December 31 of each year
during the term of the agreement. At UroGen's option, the amounts may be paid by
issuing to Baxter the number of shares of Series B Preferred Stock determined by
dividing the outstanding amount under the Credit Agreement by one thousand. The
balance has been presented as a non-current liability on the accompanying
balance sheet due to the conversion feature and because we intend to convert the
debt rather than repay it with cash. Amounts outstanding under the Credit
Agreement do not accrue interest unless UroGen is in default, in which case the
amount due bears interest at prime plus 4%. In January 1999, we issued 704
shares of Series B Preferred Stock to convert $704,000 outstanding under the
Credit Agreement. The remaining $340,276 will be converted at December 31, 1999.

UroGen entered into a Distribution Agreement with Baxter under which Baxter
will have an exclusive, worldwide right to market, sell and distribute all
products which may be developed under the Developmental Collaboration Agreement.
The term of the Distribution Agreement is the longer of ten years from the date
of regulatory approval of the first product or the expiration of the last to
expire of any related patents issued on or before ten years from the date of
regulatory approval. 

UroGen, Baxter and certain founding shareholders entered into the Investor
Rights Agreement under which the shares held by these entities are subject to
certain restrictions on transferability of the shares until July 8, 2003 and
have certain registration rights. Additionally, under this agreement, Baxter has
the right to purchase up to twenty percent of any new securities issued and has
the obligation to purchase Series C Preferred Stock at a price of $1,000 per
share upon our achievement of the following milestones: (i) $2,000,000 upon
treatment of the first patient in a Phase I clinical trial for a product
developed under the Developmental Collaboration Agreement; (ii) $5,000,000 upon
commencement of Phase III clinical trials of a product developed under the
Developmental Collaboration Agreement; and (iii) $10,000,000 upon approval by
the Food and Drug Administration of a product developed under the Developmental
Collaboration Agreement.

MEDSTONE AGREEMENTS
- -------------------

  UroGen was incorporated on June 30, 1995 as a wholly-owned subsidiary of
Medstone International, Inc. UroGen was formed from the medical biology and
small molecule pharmaceuticals divisions of Medstone, which were started in
1991. From 1991 until the distribution described below on February 9, 1996,
UroGen relied upon Medstone for financial support. UroGen also relied on
Medstone for assistance with personnel management and financial administration.
Upon completion of the Distribution, UroGen began to operate independently from
Medstone.

  Prior to the Distribution, UroGen and Medstone entered into a Distribution
Agreement, Administrative Services Agreement and Contribution Agreement
(collectively, "the Intercompany Agreements"). The following are summaries of
the principal provisions of such agreements. These summaries are qualified in
their entirety by reference to the full text of such agreements, which were
filed by Urogen as exhibits to the Registration Statement on Form 10-SB filed on
January 5, 1996.

CONTRIBUTION AGREEMENT

Under the Contribution Agreement, Medstone transferred to UroGen certain
Medstone property, including certain intellectual property and other rights,
used in connection with UroGen's business and made a cash contribution of
$500,000 to UroGen.

STOCK DISTRIBUTION AGREEMENT

  On December 29, 1995, Medstone declared a dividend of all of the stock of 
UroGen Corp. to be distributed to all Medstone stockholders. Each stockholder of
Medstone received, on February 9, 1996, one share of UroGen Common Stock for 
each share of Medstone Common Stock held on the record date, December 29, 1995.

  The Stock Distribution Agreement provided that in connection with the transfer
of assets and the assumption of liabilities relating to the separation of the
business of UroGen and Medstone, that UroGen and Medstone would execute or cause
to be executed various conveyancing and assumption instruments in such forms as
the parties to the Stock Distribution Agreement agreed.

  Pursuant to the Stock Distribution Agreement, Medstone agreed to obtain all
consents, permits and authorizations necessary to transfer to UroGen any assets
associated with the UroGen business which had not been transferred by the
Distribution Date. In addition, Medstone agreed to obtain consents, permits and
authorizations necessary to permit UroGen to assume any liabilities associated
with the UroGen business which had not been assumed by UroGen by the
Distribution Date.

  The Stock Distribution Agreement sets forth the respective obligations of
Medstone and UroGen with respect to liabilities for taxes and tax returns and
other tax related filings. In general, Medstone was responsible for tax filings
of UroGen and paying those taxes (other than taxes accrued on its financial
statements) attributable to any taxable period (or that portion of any taxable
period) ending on or before the Distribution Date. UroGen is be responsible for
filing its tax returns and paying its taxes attributable to periods (or

                                       24
<PAGE>

portions of any taxable periods) commencing on or after the date immediately
following the Distribution Date. In addition, the Stock Distribution Agreement
requires Medstone and UroGen to cooperate in preparing those filings which cover
overlapping taxable periods that include the distribution Date.

  The Stock Distribution Agreement also provided that each party agreed to
indemnify and hold the other harmless from certain liabilities, including claims
resulting from any breach of representations and warranties made by the
indemnifying party in connection with the Distribution.

ADMINISTRATIVE SERVICES AGREEMENT

  Under the Administrative Services Agreement, Medstone provided certain public
reporting assistance services to UroGen and, under this agreement, Medstone also
provided to UroGen the use of certain facilities.  In consideration for such
services and the use of such facilities, UroGen paid to Medstone an hourly fee
of $100.  Pursuant to the terms of the Administrative Services Agreement, UroGen
and Medstone contracted employee services from each other for a period not to
exceed two years following the Distribution Date. There were no payments to 
Medstone during 1998 or 1997.

SIDNEY KIMMEL CANCER CENTER

  Sidney Kimmel Cancer Center owns 332,000 shares of UroGen Common Stock and Dr.
Royston is Chief Executive Officer of SKCC. UroGen has entered into the
following transactions with SKCC:

  In June 1996, UroGen and SKCC entered into an affiliation agreement with a 
three year term. Under the affiliation agreement, SKCC agreed to provide the 
following services: (i) to allow Dr. Royston to serve as UroGen's Chief 
Executive Officer and devote part time executive services to UroGen; (ii) to 
lease approximately 100 square feet of office space in SKCC's facility; (iii) to
allow UroGen to consult and confer with scientific staff of SKCC; and (iv) to 
make available clerical support for up to ten hours per week at a compensation 
rate of $10.00 per hour. In exchange UroGen agreed to make the following 
payments: (i) cash consideration of $3,000 per month; conveyance of certain 
equipment with a book value of approximately $42,000; and 339,000 shares of 
UroGen Corp. Common Stock. The affiliation agreement was amended in May 1997 to 
reduce the monthly cash consideration to $1,000 due to Dr. Royston's resignation
as Chief Executive Officer of UroGen.

  In September 1997, the affiliation agreement was terminated and UroGen signed 
a sublease agreement with SKCC for use of approximately 500 square feet of 
office and laboratory space on a month to month basis. The monthly rent for the 
space was $1,065.

  In August 1998, UroGen and SKCC entered into a new sublease agreement for
approximately 4,800 square feet of office and laboratory space. The monthly
lease payment is approximately $14,800 plus our share of facility expenses. The
lease expires in May 2000.

  In November 1997, UroGen entered into a license agreement with an individual 
and SKCC under which UroGen obtained an exclusive right to certain technology 
for commercial purposes. UroGen is obligated to pay royalties on its net sales 
revenues and a percentage of revenues from sublicenses relating the technology 
(the "Running Royalties"). Additionally, UroGen is required to make minimum 
annual royalties of $30,000 for the duration of the agreement. The minimum 
annual royalties may be credited against Running Royalties for that year. If 
there are no Running Royalties to offset the annual royalty, one-half of the 
annual royalty may be carried forward to offset Running Royalties from the 
following year. Within thirty days of UroGen entering into an agreement with a 
corporate partner or strategic alliance relationship related to this technology,
UroGen must pay a minimum of $12,500 per month to fund additional research.

OTHER TRANSACTIONS

  In July 1998, we received $1,030,000 representing proceeds from the sale of
unsecured convertible notes payable which bear interest at 8% per annum and are
due on June 30, 1999, unless previously converted. The notes are convertible
into Common Stock at $1.00 per share. The notes are convertible, at the option
of the holder, into Common Stock at $1.00 per share and automatically convert
into Common Stock immediately prior to the filing of any registration statement
to registered the resale of the underlying shares. In addition, each note holder
received a warrant to purchase a number of shares of Common Stock of UroGen
equal to one share for each $2.00 of principal under the purchased note. The
warrants are exercisable for seven years from issuance and have an exercise
price of $0.74 per share. The following UroGen officers and directors
participated in this transactions: Mr. Quadros, Dr. Sobol and Dr. Royston each
purchased notes for $50,000 and received a warrant for 25,000 shares of Common
Stock.

  In July 1997, UroGen issued warrants to purchase 200,000 shares of Common
Stock to Dr. Sobol. These warrants are exercisable at $0.05 per share (the fair
market value of the Common Stock on the date of grant) and expire on July 31,
2001.

                        Report of Independent Auditors

The Board of Directors
UroGen Corp.

We have audited the accompanying consolidated balance sheets of UroGen Corp. (a
development stage enterprise) as of December 31, 1998 and 1997 and the related
consolidated statements of operations, stockholders' equity, and cash flows for
each of the three years in the period ended December 31, 1998 and the period
from July 1, 1991 (inception) to December 31, 1998. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing standards
which 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 consolidated financial statements referred to above present
fairly, in all material respects, the financial position of UroGen Corp. (a
development stage enterprise) at December 31, 1998 and 1997, and the results of
their operations and their cash flows for each of the three years in the period
ended December 31, 1998 and the period from July 1, 1991 (inception) to December
31, 1998, in conformity with generally accepted accounting principles.

As discussed in Note 1 to the financial statements, the Company has reported
accumulated losses during the development stage aggregating $8,705,563 and
without additional financing, lacks sufficient working capital to fund
operations through December 1999, which raises substantial doubt about its
ability to continue as a going concern. Management's plans as to these matters
are described in Note 1. The 1998 financial statements do not include any
adjustments to reflect the possible future effects on the recoverability and
classification of assets or the amounts and classification of liabilities that
may result from the outcome of this uncertainty.

1.   ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION

UroGen Corp. (the "Company"), a Delaware corporation, was incorporated on June
30, 1995, as a wholly-owned subsidiary of Medstone International, Inc.
("Medstone"). The Company was formed from the medical biology and small molecule
pharmaceuticals divisions of Medstone to continue the effort, started in 1991,
to develop pharmaceuticals to treat diseases in urology, with a particular
interest in prostate cancer. UroGen operated as two divisions of Medstone from
July 1, 1991 to December 29, 1995.

DISTRIBUTION AND CAPITALIZATION

On December 29, 1995, Medstone declared a dividend of all of the stock of UroGen
Corp. to be distributed to all Medstone stockholders. Each stockholder of
Medstone received, on February 9, 1996, one share of UroGen Common Stock for
each share of Medstone Common Stock held on the Record Date, December 29, 1995.
The distribution resulted in the receipt by record holders of Medstone Common
Stock of all of UroGen's outstanding Common Stock. Upon completion of the
Distribution, there were 5,616,528 shares of UroGen Common Stock outstanding.

The distribution occurred on February 9, 1996, on which date Medstone also
contributed to the capital of UroGen Corp. $500,000 cash. For financial
reporting purposes, the distribution and contribution to capital have been
considered effective as of January 1, 1996, and the operations of the business
have been considered those of UroGen Corp. effective that date.

Additionally, effective January 1, 1996, Medstone executed a forgiveness of all
intercompany advances resulting from the prior divisional funding of operations
between Medstone and UroGen.

BASIS OF PRESENTATION

The consolidated financial statements include the accounts of UroGen Corp. and
its wholly-owned subsidiary. All significant intercompany transactions and
balances have been eliminated in consolidation.

The accompanying financial statements for the year ended December 31, 1998 have
been prepared assuming the Company will continue as a going concern. However,
the Company incurred net losses of $7,962,388 during 1998 and has a deficit
accumulated during the development stage of $8,705,563 at December 31, 1998.
During 1999, management intends to raise additional debt and/or equity financing
to fund future operations and to provide additional working capital. However,
there is no assurance that such financing will be consummated or obtained in
sufficient amounts necessary to meet the Company's needs.

The accompanying financial statements do not include any adjustments to reflect
the possible future effects on the recoverability and classification of assets
or the amounts and classifications of liabilities that may result from the
possible inability of the Company to continue as a going concern.

                                       32

CASH AND CASH EQUIVALENTS

The Company considers all highly liquid investments with an original maturity of
three months or less when purchased to be cash equivalents.

PROPERTY AND EQUIPMENT

Property and equipment is stated on the basis of cost. Depreciation is computed
using the straight-line method over the useful lives of the assets, estimated at
three to five years.

STOCK BASED COMPENSATION

The Company grants stock options for a fixed number of shares to employees with
an exercise price equal to the fair value of the shares at the date of grant.
The Company accounts for stock option grants to employees in accordance with APB
Opinion No. 25, Accounting for Stock Issued to Employees, and, accordingly,
recognizes no compensation expense for the stock option grants to employees.

NET LOSS PER SHARE

Net loss per share is computed on the basis of the weighted average number of
common shares outstanding during the periods presented. Loss per share assuming
dilution is computed on the basis of the weighted-average number of common
shares outstanding and the dilutive effect of all common stock equivalents and
convertible securities. Net loss per share assuming dilution for the years ended
December 31, 1998, 1997 and 1996 is equal to net loss per share due to the fact
that the effect of common stock equivalents outstanding during the periods,
including stock options, warrants and convertible debt, are antidilutive.

INCOME TAXES

The Company provides for income taxes under the principles of Statement of
Financial Accounting Standards No. 109, which requires that provision be made
for taxes currently due and for the expected future tax effects of temporary
differences between book and tax bases of assets and liabilities.

RESEARCH AND DEVELOPMENT

Research and development costs are expensed as incurred. 

COMPREHENSIVE INCOME

During 1998, the Company adopted Statement of Financial Accounting Standards No.
130, Reporting Comprehensive Income ("SFAS 130"). SFAS 130 requires that all
components of comprehensive income, including net income, be reported in the
financial statements in the period in which they are recognized. Comprehensive
income is defined as the change in equity during a period from transactions and
other events and circumstances from non-owner sources. Net income and other
comprehensive income, including foreign currency translation adjustments, and
unrealized gains and losses on investments, shall be reported, net of their
related tax effect, to arrive at comprehensive income. Comprehensive income
(loss) was not different than net income (loss) in 1997 or 1998.

USE OF ESTIMATES

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

RECLASSIFICATIONS

Certain reclassifications of prior year balances have been made to conform to
the current year presentation.

2.   ACQUISITION OF TECHNOLOGY AND RELATED AGREEMENTS

In July 1998, the Company executed various agreements with Baxter Healthcare
Corporation pursuant to which the Company acquired certain rights and assets
from Baxter. Under the terms of the agreements, the Company obtained the rights
to Baxter's adenoviral-based gene transfer technologies and certain equipment in
exchange for 5,830 shares of non-voting convertible Series A Preferred Stock and
1,841,219 shares of Common Stock of the Company. The shares issued to acquire
the gene transfer technologies were valued at $5,455,505 based on the fair value
of the stock on the date of issuance and was charged to acquired in-process
technology due to the early stage of development of such technology. The value
of the stock issued for fixed assets was $343,937 based upon the fair value of
those assets.

Baxter will provide funding to the Company for continued research and
development of this technology as it relates to the treatment of hemophilia
under the Developmental Collaboration Agreement. Baxter will provide such
funding through the date on which the treatment of the first patient in a Phase
I clinical trial begins. This development funding is provided under a Credit
Agreement. The balance outstanding under the Credit Agreement as of December 31,
1998 was $1,044,275. Under the terms of the Credit Agreement, the amounts
outstanding under the Credit Agreement are due and payable on December 31 of
each year during the term of the agreement. At the Company's option, the amounts
may be paid by issuing to Baxter the number of shares of Series B Preferred
Stock determined by dividing the outstanding amount under the Credit Agreement
by one thousand. The balance has been presented as a non-current liability on
the accompanying balance sheet due to the conversion feature and because the 
Company intends to convert the debt rather than repay it with cash. Amounts
outstanding under the Credit Agreement do not accrue interest unless the Company
is in default, in which case the amount due bears interest at prime plus 4%. In
January 1999, the Company issued 704 shares of Series B Preferred Stock to
convert $704,000 outstanding under the Credit Agreement. The remaining $340,276
will be converted at December 31, 1999.

The Company entered into a Distribution Agreement with Baxter whereby Baxter
will have an exclusive, worldwide right to market, sell and distribute all
products which may be developed under the Developmental Collaboration Agreement.
The term of the Distribution Agreement is the longer of ten years from the date
of regulatory approval of the first product or the expiration of the last to
expire of any related patents issued on or before ten years from the date of
regulatory approval. 

The Company, Baxter and certain founding shareholders (the "Founders") entered
into the Investor Rights Agreement under which the shares held by these entities
are subject to certain restrictions on transferability of the shares until July
8, 2003 and have certain registration rights. Additionally, under this
agreement, Baxter has the right to purchase up to twenty percent of any

                                       34
<PAGE>
 
new securities issued and has the obligation to purchase Series C Preferred
Stock at a price of $1,000 per share upon the Company's achievement of the
following milestones: (i) $2,000,000 upon treatment of the first patient in a
Phase I clinical trial for a product developed under the Developmental
Collaboration Agreement; (ii) $5,000,000 upon commencement of Phase III clinical
trials of a product developed under the Developmental Collaboration Agreement;
and (iii) $10,000,000 upon approval by the Food and Drug Administration of a
product developed under the Developmental Collaboration Agreement.

</TABLE>

4.   NOTES PAYABLE

In July 1998, the Company received $1,030,000, representing proceeds from the
sale of unsecured convertible notes payable, which bear interest at 8% per annum
and are due on June 30, 1999, unless previously converted. The notes are
convertible, at the option of the holder, into common stock at $1.00 per share,
and automatically convert into common stock immediately prior to the filing of
any registration statement to register the resale of the underlying shares.

In addition, each note holder received a warrant to purchase a number of shares
of common stock of the Company equal to one share for each $2.00 of principal
under the purchased note. The warrants are exercisable for seven years from
issuance and have an exercise price of $0.74 per share. The fair value of the
warrants is being amortized to interest expense over the term of the notes.
Amortization during the year ended December 31, 1998 was $265,640.

5.   STOCKHOLDERS' EQUITY

PREFERRED STOCK

The Company is authorized to issue 5,000,000 shares of Preferred Stock $0.01 par
value. As of December 31, 1998, 40,000, 10,000 and 17,000 shares were designated
Series A, Series B and Series C, respectively.

As of December 31, 1998, there were 5,830 shares of Series A Preferred Stock
outstanding. Holders of the Series A Preferred Stock are not entitled to receive
dividends, have a liquidation preference amount of ten dollars ($10.00) per
share and have no voting rights. The Series A Preferred Stock is convertible to
Common Stock on a 1000 to 1 basis; provided, however, that no shares are
convertible prior to July 8, 2001.

As of December 31, 1998, there were no shares of Series B Preferred Stock issued
and outstanding. It is anticipated that Series B Preferred Stock will be issued
only to Baxter in payment for amounts funded by Baxter under the Credit
Agreement. Holders of the Series B Preferred Stock are not entitled to receive

                                       36
<PAGE>
 
dividends, have a liquidation preference amount of one thousand dollars
($1,000.00) per share prior to any distribution to holders of Series A Preferred
Stock and holders of Common Stock and have no voting rights, except for a vote
as to whether the Company may issue additional Series B Preferred Stock. The
Series B Preferred Stock may be converted into Common Stock or to Series A
Preferred Stock at the option of the holder, and converts automatically to
Common Stock upon the earlier of (i) the first business day following the
treatment of the first patient under an Initial New Drug Application for a
Collaboration Product (as defined) commences in a Phase I Clinical Trial (the
"IND Milestone Date"), (ii) the date five years after the last advance of funds
by Baxter under the Credit Agreement between Baxter and the Company through and
including the IND Milestone Date and (iii) automatic conversion pursuant to the
terms of the Credit Agreement. The Series B Preferred Stock is convertible to
Common Stock in an amount equal to (a) the quotient of (i) the Liquidation Value
(adjusted for recapitalizations), divided by (ii) one hundred and ten percent
(110%) of the per share Fair Market Value of the Company's Common Stock (as
defined), multiplied by (b) the number of shares of Series B Preferred
converted. The Series B Preferred Stock is convertible into Series A Preferred
on a one for one basis. The "Liquidation Value" is initially $1,000 per share of
Series B Preferred. In January 1999, 704 shares of Series B Preferred Stock were
issued to Baxter to convert $704,000 outstanding under the Credit Agreement.

As of December 31, 1998, there were no shares of Series C Preferred Stock issued
and outstanding. It is anticipated that Series C Preferred Stock will be sold
only to Baxter upon UroGen meeting certain specified milestones (the "Series C
Milestones"). Holders of the Series C Preferred Stock are not entitled to
receive dividends, have a liquidation preference amount of one thousand dollars
($1,000.00) per share prior to any distribution to holders of Series A Preferred
Stock and to holders of Common Stock and have no voting rights, except as to the
issuance of additional Series C Preferred Stock. Each share of Series C
Preferred may be converted into Common Stock or to Series A Preferred Stock at
the option of the holder, and converts automatically to Common Stock upon the
earlier of (i) the first business day following the approval by the FDA of the
right to market, sell or distribute any product using the Mini-Ad Vector
Technology for treatment of blood clotting disorders in humans relating to
Hemophilia A, which product has been developed pursuant to the Developmental
Collaboration Agreement between Baxter and the Company and (ii) the date seven
years after the achievement of the most recently achieved Series C Milestone.
The Series C Preferred Stock is convertible to Common Stock in an amount equal
to (a) the quotient of (i) the Liquidation Value (adjusted for
Recapitalizations), divided by (ii) one hundred and ten percent (110%) of the
per share Fair Market Value of the Company's Common Stock (as defined),
multiplied by (b) the number of shares of Series C Preferred converted. The
Series C Preferred Stock is convertible into Series A Preferred on a one for one
basis.

COMMON STOCK

The Company is authorized to issue 40,000,000 shares of Common Stock $0.001 par
value. As of December 31, 1998, there are 9,378,538 shares issued and
outstanding.

In February 1997, the Company entered into a License Agreement with The Immune
Response Corporation (the IRC License), a public biotechnology company. The
Company obtained an exclusive license to use certain patented technologies to
develop and commercialize products based upon the licensed patent rights. The
IRC License requires the Company to pay future cash royalties to the licensor
based upon net sales. In connection with this agreement, the Company entered
into a Stock and Warrant Purchase Agreement with IRC whereby the Company issued
147,791 shares of Common Stock at $.05 per share for total proceeds of $7,390.
See description of the Immune Response Corporation warrant below.

WARRANTS

Holders of the convertible notes payable also hold warrants to purchase 515,000
shares of Common Stock at an exercise price of $0.74 per share (Note 4).

                                       37
<PAGE>
 
The Company granted to IRC a warrant to purchase additional shares in the
Company to maintain a fully-diluted ownership percentage of two percent (2%) or
increase its ownership percentage up to three percent (3%). Such warrant rights
are exercisable at prices ranging from $.03 to $.04 per share. Such warrant
rights expire sixty days after the later of March 5, 1999 or the first date on
which the aggregate outstanding shares of the Company equals or exceeds
15,000,000 shares on a fully diluted basis.

In 1997 the Company issued warrants to purchase 200,000 shares of Common Stock
to an officer of the Company. These warrants are exercisable at $.05 per share
and expire on July 31, 2001.

STOCK OPTIONS

The 1995 Director Option Plan (the "Director Plan") was adopted by the Board and
approved by the stockholders in 1995, to provide automatic, nondiscretionary
grants of options to non-employee directors of the Company. A total of 100,000
shares of Common Stock have been reserved for issuance under the Director Plan.
The Director Plan provides that each non-employee director is automatically
granted an option to purchase 10,000 shares of UroGen Common Stock upon his or
her initial election or appointment as a non-employee director. Subsequently,
each non-employee director who has served for at least six months will be
granted an additional option to purchase 5,000 shares of UroGen Common Stock on
December 31 of each year so long as he or she remains a non-employee director.
The exercise price of options granted to non-employee directors must be the fair
market value of UroGen Common Stock on the date of grant.

Options granted to non-employee directors have a ten-year term, subject to a
non-employee director's continued service as a director. The initial options
granted to non-employee directors vest over three years at the rate of one-third
per year and the annual options vest one year from the date of grant. As of
December 31, 1998, options to purchase 35,000 shares of Common Stock to non-
employee directors had been granted under The Director Option Plan and options
to purchase 20,000 shares were vested.

The 1995 Stock Plan was adopted by the Board of Directors (the "Board") and 
authorized by the Stockholders in 1995 and authorizes the Board or one or
more committees which the Board may appoint from among its members (the
"Committee"), to grant options and rights to purchase Common Stock to officers,
key employees consultants and certain advisors to the Company. Options granted
under the 1995 Stock Plan may be either "incentive stock options" as defined in
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"), or
nonstatutory stock options, as determined by the Board or the Committee. The
1995 Stock Plan initially reserved 1,850,000 shares for issuance under the Plan
to be increased the first day of each year by the number of shares equal to two
percent of the Company's total outstanding common shares. Options granted
pursuant to the 1995 Stock Plan above have exercise periods of ten years and
vest over one to four years.

As of December 31, 1998, management and the Board had committed to issue options
to purchase 2,391,183 shares of Common Stock to employees under a new stock
option plan once adopted by the Board.

The Company has elected to follow Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees" (APB 25) and related interpretations
in accounting for its employee and director stock options and warrants, because,
as discussed below, the alternative fair value accounting provided

                                       38
<PAGE>
 
for under SFAS 123, "Accounting for Stock-based Compensation," requires use of
option valuation models that were not developed for use in valuing employee and
director stock options and warrants. Under APB 25, when the exercise price of
the Company's employee stock options equals the market price or fair value of
the underlying stock on the date of grant, no compensation expense is
recognized.

The following table summarizes the activity of the Company's stock options:

Pro forma information regarding net loss and net loss per share is required by
SFAS 123, and has been determined as if the Company had accounted for its
employee stock options under the fair value method of that statement. The fair
value for these options was estimated at the date of grant using a Black-Scholes
option pricing model with the following weighted-average assumptions for 1998
and 1997: a risk-free interest rate of 6%, a dividend yield of 0%, a volatility
factor of the expected market price of the Company's common stock of 65% and
50%, respectively, and an expected life of the option of two to five years.

For purposes of pro forma disclosures, the estimated fair value of the options
is amortized to expense over the options' vesting period. The Company's pro
forma information follows:

 
                                      1998             1997
                                   ------------     -----------
Pro forma net loss                 $(7,964,255)     $(307,352)
Pro forma net loss per share       $     (1.00)     $   (0.04)


The pro forma results above for 1998 and 1997 are not likely to be
representative of the effects of applying SFAS 123 on reported net income or
loss for future years as these amounts reflect the expense for less than four
years of vesting.

6. INCOME TAXES

Prior to the distribution of UroGen Common Stock by Medstone, income taxes had
been allocated to the Company on a "separate return" basis whereby such amounts
were determined as if the Company were a separate taxable entity. However, the
Company's net operating losses and research and development credits incurred
through December 31, 1995 were included in the consolidated tax returns of
Medstone and were fully utilized. As a result, the Company's available net
operating losses and research and development credits to offset future taxable
income are limited to amounts incurred during the three-year period ended
December 31, 1998. The Company has established a valuation allowance to fully
offset its deferred tax assets in accordance with Statements of Financial
Accounting Standards No. 109, "Accounting for Income Taxes." Accordingly, no
benefit for the Company's deferred tax assets has been recognized, as its
realization is uncertain.

                                       40

Deferred tax assets are comprised of the following:

As of December 31, 1998, the Company has Federal and state net operating loss
carryforwards of approximately $3,146,000 and $3,184,000, respectively, which
will begin to expire in 2011 and 2001, respectively, unless previously utilized.

The company has Federal and state research and development credit carryforwards
of approximately $75,000 and $37,000, respectively, which will begin to expire
in 2011 unless previously utilized.

Under Internal Revenue Code Sections 382 and 383, the Company's use of its net
operating loss and tax credit carryforwards could be limited in the event of
certain cumulative changes in the Company's stock ownership.

milestone payment to Immune Response Corporation of $200,000 upon the approval
by the Food and Drug Administration or the governing health authority of any
other country of its first product related to the licensed technology. This fee

and a percentage of revenues from sublicenses relating the technology (the
"Running Royalties"). Additionally, the Company is required to make minimum
annual royalties of $30,000 for the duration of the agreement. The minimum
annual royalties may be credited against Running Royalties, as defined, for that
year. If there are no Running Royalties to offset the annual royalty, one-half
of the annual royalty may be carried forward to offset Running Royalties from
the following year. Within thirty days of the Company entering into an agreement
with a corporate partner or strategic alliance relationship related to this
technology, the Company shall pay a minimum of $12,500 per month to fund
additional research.

In September 1996, the Company entered into a license agreement with the Regents

licensed products or methods. A minimum annual royalty of $50,000 is payable
beginning with the year of first commercial sale of licensed product, but no
later than the fifth year of the agreement. The minimum annual royalty will be
credited against earned royalty due for the year in which the annual minimum
payment was made.
