Item 1.  BUSINESS

UroGen Corp. (the "Company") is a development-stage company which is primarily
engaged in the development of pharmaceuticals to treat prostate cancer.  The
Company was inactive until January 1, 1996, at which date the operations of the
business, which previously operated as two divisions of Medstone International,
Inc. ("Medstone") from July 1, 1991 through December 31, 1995, were transferred
to the new company.

UroGen Corp., a Delaware corporation, was incorporated on June 30, 1995, as a
wholly-owned subsidiary of 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 a
division of Medstone from July 1, 1991 to December 29, 1995.

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.

The objective of the Company is to develop novel molecular medicines and
diagnostic products for prostate cancer and other urological disorders through
pioneering applications of molecular biology, genomics technology and
immunology.  The initial focus of the Company's research and development efforts
will be the generation of products for the treatment and diagnosis of 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 335,000
new cases in the United States.  The Company's broad core technologies have been
integrated to rapidly develop novel therapeutic and diagnostic products.  The
Company's proprietary molecular therapies have both intrinsic anti-tumor
activity and sensitize tumors to the effects of standard cancer therapies.  The
Company believes that this dual mode of action will have significant benefits in
the treatment of prostate cancer and other disorders.

The Company has also developed ultra sensitive diagnostic techniques to detect
tumor metastases which will find application in guiding decisions regarding the
choice and duration of prostate cancer treatment.  In addition, the Company
believes that its proprietary gene discovery technologies will lead to the
identification of novel gene targets for the development of second generation
therapeutic and diagnostic products employing the core technologies.

Therapeutics Programs
- ---------------------

Radiation Sensitization Immunogene Therapy

Successful treatment of prostate cancer requires complete eradication of tumor
within the prostate and the elimination of metastatic tumor cells which have
migrated from the prostate in approximately 50% of patients at the time of
diagnosis.  The Company believes its proprietary immonogene therapy technology
sensitizes tumors to the effects of radiation providing improved treatment of
disease within the prostate and simultaneously induces anti-tumor immunity
capable of destroying metastatic lesions.  The Company's first molecular
immunotherapy will employ the intratumoral injection of cells genetically
modified to express the cytokine gene interleukin-3 (IL-3).  IL-3 has been shown
to sensitize tumors to the effects of

                                       3
<PAGE>
 
radiation and to stimulate anti-tumor immune responses capable of eradicating
metastatic disease. This immunogene therapy approach has been shown to cure
tumors in animal models. This unique therapeutic may be suited for the treatment
of prostate cancer that requires elimination of tumor both within the prostate
and the metastatic sites. Current surgical and radiation treatments are
incapable of eradicating metastatic disease. The Company anticipates that a
Phase I clinical trial of the IL-3 radiation sensitizing immunogene therapy
should begin within the next twelve months.


Therapy Sensitization by Inhibition of Jun Kinase

Advances in the molecular biology of cancer during the past decade have lead to
the identification of the genes involved in the etiology of malignancies.  It is
now known that the genes which mediate the malignant process are aberrantly
functioning versions of naturally occurring genes which normally regulate cell
proliferation, cell differentiation/maturation and cellular responses to injury.
The Company demonstrates licensed technology that that molecular inhibition of
Jun kinases expression enhanced the sensitivity of prostatic carcinoma cells to
the effects of chemotherapy and radiation.  Antisense oligonucleotides are small
pieces of DNA that bind to and inactivate genes that have complimentary genetic
sequences.  The Company plans to develop with a corporate partner, antisense
compounds against Jun kinases for future application in clinical trials in
prostate cancer patients.  These Jun kinase antisense compounds will also be
combined with chemotherapy and radiation in an effort to identify the most
effective therapies for future clinical applications.


Diagnostics Program
- -------------------

Ultra-sensitive Molecular Diagnostic Products To Detect Metastatic Disease

Standard therapy for prostate cancer incorporates surgery, radiation and
hormonal drug treatment depending upon the stage of disease progression.  Only
prostatic tumors that are localized to the prostate gland can be cured by
conventional surgery or radiotherapy.  These treatments are reserved for
individuals with localized cancer that has not spread outside of the prostate
gland as these therapies may result in impotence or incontinence in some
patients.  Current methods for detecting tumor cells outside of the prostate are
unsatisfactory and many men with metastatic disease that cannot be cured by
surgery and radiation therapies are subjected to the risks of these procedures.
The Company has licensed from University of California an extremely sensitive,
proprietary diagnostic method to detect metastases based upon novel applications
of nucleic acid amplification techniques termed reverse transcription polymerase
chain reaction (RT-PCR). These diagnostic methods will, with a corporate
partner, be applied to identify patients with metastatic disease who may not be
appropriate candidates for surgery and current radiation therapies.


Gene Discovery/Genomics Program

The Company has licensed proprietary gene discovery methods which permit rapid
sequencing of expressed genes and the ability to identify genes that are
expressed by different types of tissues in different physiological states.  The
Company's genomics efforts have been designed to advance each of the ongoing
research programs. Novel gene discovery techniques will be utilized to identify
genes associated with the causation, progression and therapy resistance of
prostate cancer.

The Company's novel gene discovery technologies may also be applied to detect
genes that are turned on or off in response to various treatments permitting the
identification of genes which mediate sensitivity or resistance to therapy.
This information will subsequently be employed in an effort to develop novel
treatment approaches aimed at increasing or decreasing the expression of
sensitivity and resistance genes respectively to enhance the efficacy of
conventional therapies.  Further characterization of these marker genes may also
identify additional therapeutic targets for drug development.  The
identification of genes that are differentially expressed between BPH and
prostate cancers will further our diagnostics program and enable more
sophisticated applications of our proprietary RT-PCR assays for diagnosis,
staging and treatment monitoring.


Competition

UroGen is engaged in a rapidly changing field.  Existing therapies and products
to treat prostate disorders will compete directly with the products that the
Company is seeking to develop and market.  Competition

                                       4
<PAGE>
 
from fully integrated pharmaceutical companies and more established
biotechnology companies is expected to increase. Most of these companies have
significantly greater financial resources and expertise in research and
development, manufacturing, preclinical and clinical testing, obtaining
regulatory approvals and marketing than the Company. Smaller companies may also
prove to be significant competitors, particularly through collaborative
arrangements with large pharmaceutical companies. Many of these competitors have
significant prostate and urological system products approved or in development
and operate large, well funded research and development programs. Academic
institutions, governmental agencies and other public and private research
organizations also conduct research, seek patent protection and establish
collaborative arrangements for product and clinical development and marketing.
These companies and institutions compete with the Company in recruiting and
retaining highly qualified scientific and management personnel. In addition to
the above factors, UroGen will face competition based on product efficacy,
safety, the timing and scope of regulatory approvals, availability of supply,
marketing and sales capability, reimbursement coverage, price and patent
position. There is no assurance that the Company's competitors will not develop
more effective or more affordable products, or achieve earlier patent protection
or product commercialization than the Company. Additionally, there is no
assurance that technologies developed by others will not render the potential
products of the Company uneconomical or obsolete, or that the Company will be
successful in marketing its potential products against competitors.


Government Regulation

The production and marketing of the Company's products and its ongoing research
and development activities will be subject to extensive regulation by numerous
governmental authorities in the United States and other countries.  Prior to
marketing in the United States, any drug developed by the Company must undergo
rigorous preclinical (animal) and clinical (human) testing and an extensive
regulatory approval process implemented by the FDA under the Food, Drug and
Cosmetic Act.  Satisfaction of such regulatory requirements, which includes
satisfying the FDA that the product is both safe and effective, typically takes
several years or more depending upon the type, complexity and novelty of the
product and requires the expenditure of substantial resources.  Clinical trials
are rigorously regulated.  Preclinical studies must be conducted in conformance
with the FDA's good laboratory practice ("GLP") regulations.  Clinical testing
must meet requirements for institutional review board oversight and informed
consent, as well as FDA prior review, oversight and good clinical practice
requirements.  The Company has limited experience in conducting and managing the
preclinical and clinical testing necessary to obtain regulatory approval.
Clinical trials in the United States frequently require large numbers of test
subjects.  There can be no assurance that those conducting clinical trials for
the Company will be able to initiate trials at preferred clinical test sites,
recruit sufficient test subjects or that clinical trials will be started or
completed successfully within any specified time period, if at all, with respect
to any of the Company's products.  Furthermore, the Company or the FDA may
suspend clinical trials at any time if it is felt that the subjects
participating in such trials are being exposed to unacceptable health risks.
There can be no assurance that the Company will not encounter problems in
clinical trials which will cause the Company or the FDA to delay or suspend
clinical trials.

There can be no assurance that any compound developed by the Company alone or in
conjunction with others will prove to be safe and efficacious in clinical trials
and will meet all of the applicable regulatory requirements needed to receive
marketing approval.  Before receiving FDA approval to market a product, the
Company may have to demonstrate that the product represents an improved form of
treatment compared to existing therapies.  Data obtained from preclinical and
clinical activities are susceptible to varying interpretations which could
delay, limit or prevent regulatory approvals.  In addition, delays or rejections
may be encountered based upon additional government regulation from future
legislation or administrative action or changes in FDA policy during the period
of product development and FDA regulatory review.  Similar delays may be
encountered in foreign countries.  There can be no assurance that even after
such time and expenditures, regulatory approval will be obtained for any
products developed by the Company.  If regulatory approval of the product is
granted, such approval will be limited to those disease states and conditions
for which the product is useful, as demonstrated through clinical studies.
Furthermore, approval may entail ongoing requirements for postmarketing studies.
Even if such regulatory approval is obtained, a marketed product, its
manufacture and its manufacturing facilities are subject to continual review and
periodic inspections.  The regulatory standards for manufacturing are currently
being applied stringently by the FDA.  Discovery of previously unknown problems
with a product, manufacturer or facility may result in restrictions on such
product or manufacturer, including withdrawal of the product from the market.
Moreover, Congress has given drug pricing extensive scrutiny and is

                                       5
<PAGE>
 
considering legislation to restrict price increases of pharmaceuticals,
especially sales to the federal and state government. Legislation and
regulations affecting the formula for pricing pharmaceuticals may change before
the Company's products are approved for marketing.

The Company intends to establish collaborative relationships to conduct clinical
testing and seek regulatory approvals to market its products in major markets
outside the United States.  There can be no assurance that the Company will be
successful in establishing such relationships or that such approvals will be
received in a timely basis, if at all.  Sales of pharmaceutical products outside
the United States are subject to regulatory requirements that vary from country
to country.  In the European Union, ("EU"), the general trend has been towards
coordination of common standards for clinical testing of new drugs, leading to
changes in various requirements imposed by each EU country.  The level of
regulation in the EU and other foreign jurisdictions varies widely.  The time
required to obtain regulatory approval from comparable regulatory agencies in
each foreign country may be longer or shorter than that required for FDA
approval.

In addition, in certain foreign markets, the Company may be subject to
governmentally mandated prices.  This foreign regulatory approval process
includes all of the risks associated with FDA approval set forth above.


Intellectual Property

The Company's success will depend in part on its ability to obtain patents and
product license rights, maintain trade secrets and operate without infringing on
the proprietary rights of others, both in the United States and other countries.
The patent positions of biotechnology and pharmaceutical companies can be highly
uncertain and involve complex legal and factual questions, and therefore the
breadth of claims allowed in biotechnology and pharmaceutical patents cannot be
predicted.  There can be no assurance that patents issued to or licensed by the
Company will not be challenged, invalidated or circumvented, or that the rights
granted thereunder will provide proprietary protection or competitive advantages
to the Company.

The Company has licensed a U.S. patent application for the use of tumor radio
sensitization using gene therapy from the Immune Response Corporation (the "IRC
License").  The IRC License is a royalty-bearing license for the rights in the
field of urologenital tumors, and provides for payments upon the occurrence of
certain milestones.

The Company is obligated to make a milestone payment to IRC of two hundred
thousand dollars ($200,000) upon the approval of its first product by the FDA or
the governing health authority of any other country.  This fee can be offset
against future royalty payments.  In addition, the Company is obligated to pay
royalties on its net sales revenue and a percentage of all revenues received
from sublicenses relating to the tumor radiosensitization gene therapy
technology.  Failure to comply with the terms of the IRC License may cause its
termination, which would have a materially adverse effect on the Company.

The Company has licensed a U.S. patent application covering therapy
sensitization by inhibition of jun kinase from Daniel Mercola, M.D., Ph.D. (the
Mercola License).  The Mercola License is a royalty-bearing license for the
rights to this patent application, and provides for minimum payments and
obligations to fund sponsored research under certain conditions.  Dr. Mercola
has assigned the royalty payments to the Sidney Kimmel Cancer Center (SKCC), a
non-profit cancer research organization where Dr. Mercola conducts his research.

The Company is obligated to pay royalties on its net sales revenue and a
percentage of all revenues received from sublicenses relating to the inhibition
of jun kinase technology.  The license agreement requires the Company to pay a
minimum royalty payment of thirty thousand dollars ($30,000) per year.  Half of
the minimum payment may be used to offset future royalty obligations.

Within 30 days after the date when the Company enters into an agreement with a
corporate partner, regarding the inhibition of jun kinase, the Company is
obligated to enter into a Sponsored Research Agreement with SKCC to fund Dr.
Mercola's research in the inhibition of jun kinase at an annual rate of not less
than one hundred fifty thousand dollars ($150,000).  Failure to comply with the
terms of the Mercola License may cause its termination, which would have an
adverse effect on the Company.

                                       6
<PAGE>
 
The Company has licensed an issued U.S. patent covering the detection of
carcinoma metastases by nucleic acid amplification from the University of
California (the UC License").  The UC License is a royalty-bearing license for
the rights to such patent, and provides for minimum annual payments and payments
upon the occurrence of certain milestones.  The Company will pay $30,000, in two
$15,000 payments, as an initial license-issue fee. The first $15,000 payment was
made in September 1996 and the second payment was made in October 1997.
Beginning in September 1998 the Company is obligated to pay an annual license
maintenance fee of $10,000.

The Company is obligated to make certain milestone payments to UC as follows;
(a) twenty-five thousand dollars ($25,000) upon filing of an IDE or equivalent
with the FDA; (b) fifty thousand dollars ($50,000) per year as minimum royalty
beginning the year of the first commercial sale of Licensed Product, but no
later than the fifth anniversary of the agreement.  Failure to comply with the
terms of the UC License may cause its termination, which would have an adverse
effect on the Company.

Under the terms of the Phenotypics Research and Development Agreement (the
"Phenotypics Agreement"), Phenotypics will undertake research to discover novel
prostate genes and the identification of genes that are expressed by different
types of prostate tissue in different physiological states.  In turn, the
Company has undertaken to fund such research in the amount of fifty thousand
dollars ($50,000) in the first year.  Subsequently, the Company will provide
half of the cost of such research in each succeeding year.  Genes discovered in
this research program will be owned equally by the Company and Phenotypics.
Failure to pay its one half share of the prostate gene program will cause the
Company ownership to be decreased pro-rata on the total funds spent on the
program.  In addition, by failing to pay its share and therefore having a
minority ownership of the genes, the Company would lose control of how the genes
were used or licensed by Phenotypics.  Failure to fund its commitments to
Phenotypics would have a material adverse effect on the Company.

Competitors may have filed applications, may have been issued patents or may
obtain additional patents and proprietary rights relating to products or
processes competitive with those the Company may acquire or develop.  There is a
substantial backlog of biotechnology and pharmaceutical patents at the United
States Patent and Trademark Office (PTO).  Accordingly, the time at which the
Company's or competitors' patent applications will issue as patents cannot be
predicted.  Since patent applications in the United States are maintained in
secrecy until patents issue, and since publication of discoveries in the
scientific or patent literature often lags behind actual discoveries, the
Company cannot be certain that it was the first to discover subject matter
covered by its patent applications or patents or that it was the first to file
patent applications for such inventions.

The commercial success of the Company will also depend, in part, on not
infringing on patents issued to others and not breaching the technology licenses
upon which any Company products are based.  It is uncertain whether any third-
party patents will require the Company to alter its products or processes,
obtain licenses or cease certain activities.  A number of pharmaceutical
companies, biotechnology companies, universities and research institutions have
filed patent applications or received patents in the prostate field.  Some of
these applications or patents may be competitive with the Company's
applications, or conflict in certain respects with claims made under the
Company's applications.  Such a conflict could result in a significant reduction
of the coverage of the Company's patents, if issued.  In addition, if patents
are issued to others which contain competitive or conflicting claims and such
claims are ultimately determined to be valid, the Company may be required to
obtain licenses to these patents or to develop or obtain alternative technology.
If any licenses are required, there can be no assurance the Company will be able
to obtain any such licenses on commercially favorable terms, if at all.  The
Company's breach of an existing license or failure to obtain a license to any
technology that it may require to commercialize its products may have a material
adverse  impact on the Company. Litigation, which could result in substantial
costs to the Company, may also be necessary to enforce any patents issued to the
Company or to determine the scope and validity of third-party proprietary
technology also claimed by the Company.  The Company may have to participate in
interference proceedings declared by the PTO or litigation to determine priority
of inventions, which could result in substantial cost to the Company, even if
the eventual outcome is favorable to the Company.

There can be no assurance that the Company's patents, if issued, would be held
valid and infringed by a court of competent jurisdiction.  An adverse outcome
with regard to a third party claim could subject the Company to significant
liabilities to third parties, require disputed rights to be licensed from third
parties or require the Company to cease using such technology.

                                       7
<PAGE>
 
The Company also relies on secrecy to  protect its technology, especially where
patent protection is not believed to be approved or obtainable.  Thus, UroGen
will protect its proprietary technology and processes, in part, by
confidentiality agreements with its employees, consultants and certain
contractors. There can be no assurance that these agreements will not be
breached, that the Company would have adequate remedies for any breach, or that
the Company's trade secrets will not otherwise become known or be independently
discovered by competitors.


Employees

The Company has no full-time employees.  At present it will initially utilize
certain personnel on a part-time basis to assist with administrative, research,
clinical trails, and accounting operations.  The Company expects over time to
retain full and part-time personnel and consultants to satisfy its research and
development, marketing, production, regulatory and administrative staffing
requirements.


History of Operating Losses;  Accumulated Deficit

The Company's predecessor divisions have experienced significant operating
losses since their inception in 1991.  As of December 31, 1997, the Company's
balance sheet reflects an accumulated deficit of $743,175.  The Company expects
to incur significant additional operating losses over the next several years as
the Company's research and development efforts expand.  The Company's ability to
achieve profitability depends upon its ability, alone or with others, to
successfully complete development of pharmaceutical products, obtain required
approvals and manufacture and market its products.


Dependence Upon Key Personnel

  The Company's future success, if any, depends to a significant degree upon the
continued service of key technical and senior management personnel, the loss of
any of whose services might significantly delay the Company's efforts. Only Paul
Quadros, the Company's Chief Executive Officer, is bound by an employment
agreement,  while no member of management is covered by an insurance policy of
which the Company is the beneficiary.  In addition, the Company will rely on
consultants and advisors, including its scientific advisors, to assist the
Company in formulating its research and development strategy.  In order to
pursue its product development and marketing plans, the Company may be required
to hire additional qualified scientific personnel to  perform research and
development, as well as personnel with expertise in clinical testing, government
regulation, manufacturing, and marketing.  Product development and marketing may
also require the addition of management personnel and the development  of
additional expertise by existing management personnel.   The Company's success
depends on its ability to attract and retain such highly qualified technical and
managerial personnel. Competition for such personnel is intense, and there can
be no assurance that the Company will be able to retain its technical and
managerial employees or attract, assimilate or retain highly qualified technical
and managerial personnel in the future.  If the Company is unable to hire the
necessary technical personnel, its ability to develop new and enhanced products
could be impaired.  Failure to do so could have a material adverse effect upon
the Company's business and results of operations.  Further, a significant
portion of the Company's research and development will be conducted under
sponsored research programs with universities and other research organizations.
The Company will depend on the abilities of the principal investigator available
to conduct research and development.  The Company's collaborators will not be
employees of the Company.  As a result, the Company has limited control over
their activities and can expect that only limited amounts of their time will be
dedicated to Company activities.  The Company's collaborators may have
relationships with other commercial entities, some of which could compete with
the Company.

Item 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
         CONDITION AND RESULTS OF OPERATIONS


General

  Urogen Corp. (the "Company") is a development stage company which is primarily
engaged in the development of pharmaceuticals to treat prostate cancer.  The
Company was incorporated in Delaware on June 30, 1995.  It was inactive until
January 1, 1996, at which date the operations of the business, which previously
operated as a division of Medstone International, Inc. ("Medstone") from July 1,
1991 through December 31, 1995, were transferred to the new company.

                                       11
<PAGE>
 
  The Company, a division of Medstone prior to January 1, 1996, had no
independent operating history of its own and, to date, has generated a net loss
of $4,468,968.  Accordingly, there can be no assurances that the Company will be
able to generate sufficient revenue and cash flow to maintain its operations
beyond the $74,353 existing cash balance.  The Company must develop new products
and raise substantial additional financing.

Plan of Operation

  The Company expects that its capital resources will enable it to maintain its
current and planned operations through the second quarter of 1998.  Thereafter,
the Company will need to raise substantial additional capital to fund its
operations.  In the next twelve months UroGen will be actively pursuing
opportunities to develop and/or license or acquire new prostate cancer
therapeutics and diagnostics and novel gene therapies.

  Depending on the Company's success in identifying promising opportunities in
cancer and gene therapy, and its success in attracting additional capital,
UroGen could substantially increase its number of employees.  However, it is the
Company's current intention to use human resources on a part-time and consulting
basis for the near-term, if at all possible.

Year 2000 Compliance

  Many currently installed computer systems and software products are coded to 
accept only two digit entries to represent years. These systems and products 
will need to be able to accept four digit entries to distinguish years beginning
with 2000 from prior years. As a result, systems and products that do not accept
four digit year entries will need to be upgraded or replaced to comply with such
"Year 2000" requirements. The Company believes that its internal systems are 
Year 2000 compliant or will be replaced in connection with previously planned
upgrades to information systems prior to the need to comply with Year 2000
requirements. However, a number of the Company's customers and vendors may be
affected by Year 2000 issues that require that they expend significant resources
to modify or replace their existing systems.

Liquidity and Capital Resources

  From inception on July 1, 1991, the Company's operations have been funded
primarily by Medstone, however, such funding was completed with the $500,000
capital contribution of cash on February 9, 1996. The Company has incurred net
losses of $4,468,968 since its inception and has never been profitable during
its existence.  The Company expects to incur significant additional operating
losses over the next several years as the Company's research and development
efforts expand.  The Company's ability to achieve profitability depends upon its
ability, alone or with others, to successfully complete development of
pharmaceutical products, obtain required regulatory approvals and manufacture
and market its products.

  The Company's 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, if funding is available.  The development of the
Company's products will require a commitment of substantial funds to conduct the
costly and time-consuming research, preclinical and clinical testing necessary
to bring such products to market and to establish manufacturing and marketing
capabilities.  The Company's future capital requirements will depend on many
factors, including scientific progress in its research and development programs,
the ability of the Company 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.

  The Company expects that its existing capital resources, including the $74,353
existing cash and equivalent, its SBIR grant received in December 1997, and
contract research revenues will enable the Company to maintain its current and
planned operations through the second quarter of 1998.  The Company intends to
seek additional funding either through collaborative arrangements or through
public or private equity or debt financings. There can be no assurance that
additional financing will be available on acceptable terms or at all.  If
additional funds are raised by issuing equity securities, further dilution to
stockholders will result.  If adequate funds are not available, the Company may
be required to delay or reduce the scope of its operations or obtain funds
through arrangements with collaborative partners or others that may require the
Company to relinquish rights it may have acquired in the interim.

Results of Operations

  For the years ended December 31, 1997 and 1996, the Company had operating
revenues of $193,500 and 0, respectively, and net losses of $299,177 and
$443,998, respectively.  The smaller loss for the current period reflects the
effect of revenues during 1997 as compared to no revenue in 1996.  $143,500 of
the revenue was from a research agreement and $50,000 was from the sale of
proprietary biological materials.

Item 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

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

Intercompany Agreements

  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 have been
filed as exhibits to the Registration Statement of December 31, 1995.

Distribution Agreement

  Under the Distribution Agreement, immediately following the Distribution, all
of the UroGen Common Stock was owned by stockholders of Medstone.

  The 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.

  The 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 shall execute or cause
to be executed various conveyancing and assumption instruments in such forms as
the parties to the Distribution Agreement shall agree.

  Pursuant to the Distribution Agreement, Medstone agreed to obtain all
consents, permits and authorizations necessary to transfer and to transfer to
UroGen any assets associated with the UroGen business which had not been
transferred by the Distribution Date.  In addition, Medstone is 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 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 will be 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 shall be responsible
for filing its tax returns and paying its taxes attributable to periods (or
portions of any taxable periods) commencing on or after the date immediately
following the Distribution Date.  In addition, the Distribution Agreement
requires Medstone and UroGen to cooperate in preparing those filings which cover
overlapping taxable periods that include the Distribution Date.

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.

                                       18
<PAGE>
 
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.

                        Report of Independent Auditors

The Board of Directors
UroGen Corp.

We have audited the accompanying balance sheets of UroGen Corp. (a development
stage enterprise) as of December 31, 1997 and 1996 and the related statements of
operations, stockholders' equity, and cash flows for each of the three years in
the period ended December 31, 1997 and the period from July 1, 1991 (inception)
to December 31, 1997.  These financial statements are the responsibility of the
Company's management.  Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing standards
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 financial statements referred to above present fairly, in
all material respects, the financial position of UroGen Corp. (a development
stage enterprise) at December 31, 1997 and 1996, and the results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1997 and the period from July 1, 1991 (inception) to December 31,
1997, in conformity with generally accepted accounting principles.

As discussed in Note 1 to the financial statements, the Company's recurring
losses from operations rise substantial doubt about its ability to continue as a
going concern.  The 1997 financial statements do not include any adjustments
that might result from the outcome of this uncertainty.

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 accompanying financial statements for the year ended December 31, 1997 have
been prepared assuming the Company will continue as a going concern.  However,
the Company incurred net losses of $299,177 during 1997 and has a deficit
accumulated during development stage of $743,175 at December 31, 1997.  During
1998, 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.

Cash and Cash Equivalents

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

Financial Instruments

The following methods and assumptions were used by the Company in estimating its
fair value disclosures for financial instruments:

Cash and Equivalents:  The carrying amount reported in the balance sheet for
cash and equivalents approximates fair value.

Accounts Payable and Accrued Liabilities:  The carrying amount reported in the
balance sheet for accounts payable and accrued liabilities approximates their
fair value.

Property and Equipment

Property and equipment is stated on the basis of cost.  Depreciation is computed
principally by the straight-line method for financial reporting purposes.

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 in accordance with APB Opinion No.
25, Accounting for Stock Issued to Employees, and, accordingly, recognizes no
compensation expense for the stock option grants.

Net Loss Per Share

Loss per share is computed using the weighted average number of common shares
outstanding during the periods presented.  Common equivalent shares result from
stock 

                                       27
<PAGE>
 
options and warrants. Common equivalent shares are excluded from the computation
as their effect would be antidilutive.

In 1997, the Financial Accounting Standards Board issued Statement of Financial
Accounting Standards ("SFAS") No. 128, Earnings per Share, which supersedes APB
Opinion No. 15.  SFAS 128 replaces the presentation of primary earnings per
share (EPS) with "Basic EPS" which includes no dilution and is based on weighted
average common shares outstanding for the period.

Income Taxes

Income taxes have been provided using the liability method in accordance with
FASB Statement No. 109, Accounting for Income Taxes.

Reclassifications

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

New Accounting Standards

In June 1997, the Financial Accounting Standards board issued SFAS No. 130,
Reporting Comprehensive Income, (SFAS 130) and SFAS 131, Segment Information,
(SFAS 131).  Both these standards are effective for fiscal years beginning after
December 15, 1997.  SFAS No. 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.  The Company believes that comprehensive
income or loss will not be materially different than net income or loss.  SFAS
No. 131 amends the requirements for public enterprises to report financial and
descriptive information about its reportable operating segments.  Operating
segments, as defined in SFAS No. 131, are components of an enterprise for which
separate financial information is available and is evaluated regularly by the
Company in deciding how to allocate resources and in assessing performance.  The
financial information is required to be reported on the basis that is used
internally for evaluating the segment performance.  The Company believes it
operates in one business and operating segment and the adoption of these
standards will not have a material impact on the Company's financial statements.

2.  Related Party Balances and Transactions

During 1996, the Company issued 339,000 shares of Common Stock valued at $.05
per share and transferred fixed assets with a book value of $42,224 to a
research organization in connection with the execution of an Affiliation
Agreement and for services rendered.  Additionally, during 1997 and 1996, the
Company paid the research organization $53,741 and $67,000, respectively for
services and rent.

                                       28
<PAGE>
 
During 1997 and 1996, the Company paid four shareholders/officers a total of
$222,379 and $134,000, respectively, for consulting services.

During 1996, the Company issued 24,000 shares of Common Stock valued at $.05 per
share to a shareholder/consultant for services.


3.  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, 1997 there are no shares issued or outstanding.

Common Stock

The Company is authorized to issue 40,000,000 shares of Common Stock $0.001 par
value.  As of December 31, 1997 there are 7,537,319 shares issued and
outstanding.

In February 1997, the Company entered into a License Agreement with 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 License Agreement requires the Company to pay
future cash royalties to the licensee based upon net sales.  In connection with
this License Agreement, the Company entered into a Stock and Warrant Purchase
Agreement with the licensee whereby the Company issued 147,791 shares of Common
Stock at $.05 per share for total proceeds of $7,390.

Warrants

The Agreement granted to the licensee 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 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 200,000 warrants to purchase 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 Shareholders in 1995, to provide automatic, nondiscretionary
grants of options to non-employee directors ("Outside Directors") of the
Company.  A total of 100,000 shares of Common Stock has been reserved for
issuance under the Director Plan.  The Director Plan provides that each Outside
Director is automatically granted an 

                                       29
<PAGE>
 
option to purchase 10,000 shares of UroGen Common Stock upon his or her initial
election or appointment as an Outside Director. Subsequently, each Outside
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 an Outside Director. The exercise price of
options granted to Outside Directors must be the fair market value of UroGen
Common Stock on the date of grant. Options granted to Outside Directors have 
ten-year terms, subject to an Outside Director's continued service as a
director. Options granted to Outside Directors vest over four years at the rate
of twenty-five percent per year. As of December 31, 1997, options to purchase
15,000 shares of Common Stock to an Outside Director had been granted under The
Director Option Plan.

The 1995 Stock Plan authorizes the Board of Directors (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.

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 for under
FASB Statement No. 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 weighted average exercise prices and fair values for 1997 are as follows:

<TABLE>

</TABLE> 

Pro forma information regarding net loss and net loss per share is required by
Statement 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 1995
and 1996:  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 50%, and an
expected life of the option of two 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:

<TABLE>

</TABLE>

The pro forma results above for 1997 and 1996 are not likely to be
representative of the effects of applying FAS 123 on reported net income or loss
for future years as these amounts reflect the expense for less than four years
of vesting.

4.  Income Taxes

Prior to the Distribution, 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, have been
included in the consolidated tax returns of Medstone and have been 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 two-year period ended December 31, 1997.  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.

Deferred tax assets are comprised of the following:

</TABLE> 

As of December 31, 1997, the Company has federal and state net operating loss
carryforwards of approximately $682,000 and $694,000, 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 $22,000 and $10,000, 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.

5. Revenues

For the year ended December 31, 1997, $143,500 of the revenues was from a
research agreement, and $50,000 was from the sale of proprietary biological
materials.

6.  Commitments and Contingency

Facilities

During 1996, the company entered into a three-year Affiliation Agreement with a
research organization which provides the Company the rights to utilize certain
office space through May 31, 1999.  The agreement was amended on May 1, 1997.
Future minimum payments to the research organization under this agreement as
amended are $36,000 for 1998 and $15,000 for 1999.  For the years ended December
31, 1997 and 1996 a total of $36,000 and $67,000 was paid to the research
organization under the terms of this agreement for services and rent.

The Company is obligated to make a milestone payment to IRC of $200,000 upon the
approval of its first product by the FDA or the governing health authority of
any other country.  This fee can be offset against future royalty payments.  In
addition, the Company is obligated to pay royalties on its net sales revenue and
a percentage of all revenues received from sublicenses relating to the tumor
radiosensitization gene therapy technology.  Failure to comply with the terms of
the IRC License may cause its termination, which would have a materially adverse
effect on the Company.


7.  Subsequent Event

On March 18, 1998, the Company's Board of Directors entered into an agreement
with a major international healthcare company to merge that company's gene
therapy program and its advanced gene therapy technology into UroGen's existing
technology base.  Under the terms of the agreement, UroGen will acquire rights
to all of the related intellectual property and equipment needed to continue
research and product development in exchange for newly issued UroGen stock.  At
the conclusion of the asset acquisition, the corporate partner would be issued a
number of common shares equal to approximately 19% of the fully diluted number
of UroGen shares outstanding at that time.  In addition, the corporate partner
would also receive a larger number of shares of preferred stock that will be
convertible into common stock at a future time and under certain conditions.
Under the proposed terms, the corporate partner will also provide funding to
UroGen to continue research and product development of this technology.

The agreement has three important contingencies.  UroGen must raise a specific
minimum amount of capital by May 27, 1998, the transaction must be approved by
the board of directors of the corporate partner, and other ancillary agreements
must be negotiated and approved by both parties.  These agreements include the
financial and business relationship defining the corporate partner's ongoing
support of research and product development, and a plan for the corporate
partner to distribute UroGen products for the treatment of selected genetic
disorders.  The name of the corporate partner will be disclosed when the
contingencies are resolved.
