               NOTES TO INTERIM FINANCIAL STATEMENTS (UNAUDITED)
 
                                 JUNE 30, 1998
 
NOTE 1--BASIS OF PRESENTATION:
 
    The accompanying unaudited financial statements have been prepared in
accordance with generally accepted accounting principles for interim financial
information and with the instructions to Form 10-Q and Article 10 of Regulation
S-X. Accordingly, they do not include all of the information and footnotes
required by generally accepted accounting principles for complete financial
statements. In the opinion of management, all adjustments (consisting of normal
recurring items) considered necessary for a fair presentation have been
included. These interim financial statements should be read in conjunction with
the financial statements and notes included in the Company's Annual Report on
Form 10-K filed with the Securities and Exchange Commission on March 30, 1998.
 
    Certain reclassifications have been made in the 1997 balance sheet to
conform with the 1998 presentation. Total assets and net income for 1997 were
not affected by the reclassifications.
 
    Operating results for the three and six month periods ended June 30, 1998
are not necessarily indicative of the results that may be expected for the full
year ending December 31, 1998.
 
NOTE 2--INVESTMENT IN AND OPERATIONS OF UROLOGY SUPPORT SERVICES:
 
    The Company has invested in its Urology Support Services ("USS") business
since 1997 with the intent to deliver certain business management services to
its urology customers. Management believes that an opportunity exists for USS to
serve growing demand by urologists for a broader range of services. To
capitalize on this opportunity, USS would require resources and management focus
at a level which could result in dilution of management's focus on UroCor's core
clinical services business. Consequently, the Company recently decided to pursue
the transfer of the business and assets of USS to an independently financed
company and retain a minority interest in the resulting company by the end of
1998. The related assets are included on the balance sheet as of June 30, 1998
at net book value of approximately $1,520,000 in net property and equipment and
accounts receivable. No gain or loss is anticipated on the transfer of these
assets.
 
    Revenue, as reported for the three and six months ended June 30, 1998
includes USS revenue of approximately $31,000 and $54,000, respectively.
Operating Income, as reported for the three and six months ended June 30, 1998
includes operating losses for USS of approximately $411,000 and $723,000,
respectively. USS operating losses are anticipated to continue until the
transfer of the USS business later in 1998.
 
NOTE 3--IMPACT OF ACCOUNTING STANDARDS NOT YET ADOPTED BY THE COMPANY:
 
    In April 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-5 ("SOP 98-5"), Reporting on the Costs of Start-Up
Activities. SOP 98-5 requires that costs of start-up activities, as defined by
SOP 98-5, be expensed as incurred in financial statements for fiscal years
beginning after December 15, 1998. The Company has historically capitalized
certain costs associated with start-up activities for new products, processes or
operations and amortized the costs over a relatively short period of time
(usually 12 to 24 months). The Company will adopt SOP 98-5 in January 1999. The
Company currently has approximately $570,000 in start-up costs included on the
balance sheet as Prepaid Expenses, and Intangible and Other Assets, net,
principally related to the start-up of Urology Support Services. Given the
current rate of amortization of these start-up costs, the impact of this change
in accounting principle in January 1999 will be approximately $380,000 as a
pre-tax write-off of remaining balances.

NOTE 4--INVESTMENTS:
 
    Pursuant to the Company's investment policy, idle and excess funds are
invested in high grade, fixed income securities generally for no more than two
years. These securities are considered available-for-sale as of June 30, 1998.
The Company considers any net unrealized gain or loss on these investments to be
temporary, and reflects such gains or losses as a component of stockholders'
equity. As of June 30, 1998, there was not a material net unrealized gain or
loss on these investments.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
  OF OPERATIONS
 
    The following discussion of operations and financial condition of UroCor,
Inc. ("UroCor" or the "Company") should be read in conjunction with the
Financial Statements and Notes thereto included elsewhere in this Quarterly
Report on Form 10-Q. Special Note: Certain statements set forth below constitute
"forward-looking statements" within the meaning of Section 27A of the Securities
Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934,
as amended. See "Special Note Regarding Forward-Looking Statements" and
"Cautionary Statements" included elsewhere in this Report.
 
OVERVIEW
 
    UroCor provides a broad range of diagnostic services for the clinical
management of certain urological cancers and diseases. The Company complements
its diagnostic services by marketing and co-promoting therapeutic products for
certain of these diseases. The Company is also developing and offering related
information services intended to enhance and expand services to its clients. The
Company has established integrated capabilities to serve the needs of urologists
and managed care organizations for the diagnostic, prognostic and therapeutic
care of patients throughout the entire course of their diseases.
 
    The Company currently derives over 85% of its revenue from diagnostic
products and services that its UroDiagnostics Group provides to the urology
market to assist in the diagnosis, prognosis and management of prostate cancer,
bladder cancer and kidney stones disease. The Company recognizes revenue when
products are sold or services are rendered. The Company typically bills various
third-party payors for its products and services, including governmental
programs such as Medicare, private insurance and managed care plans, as well as
individual patients. For the six months ended June 30, 1998, approximately 45%,
42%, 8% and 5% of the Company's revenue was attributable to Medicare, private
insurance and managed care, individual patients, and physicians and hospitals,
respectively.
 
    In the fourth quarter of 1997, the Company acquired co-promotion rights to
two therapeutic products and began marketing these products to urologists. These
co-promotion efforts result in revenue that is recognized as earned under the
related agreement. The Company also has distribution rights for another
therapeutic product currently under review by the United States Food and Drug
Administration (the "FDA").
 
    In the fourth quarter of 1997, the Company started operations of the Urology
Support Services business ("USS"), which currently provides limited business
management services, primarily billing and accounts receivable management, to
selected urologist clients. The Company believes that an opportunity exists for
USS to serve growing demand by urologists for a range of business management
services that is broader than the services currently offered by USS. In order to
capitalize on this opportunity, the Company believes USS would require
deployment of resources and management focus at a level which could result in
dilution of management's focus on UroCor's core clinical services business.
Consequently, the Company recently decided to pursue the transfer of the
business and assets of USS to an independent company in which UroCor would
retain a minority interest, as a result of which USS would be independently
financed and focused solely on providing business management services to
specialty physicians. The Company expects to complete the transfer of USS by the
end of 1998.
 
RESULTS OF OPERATIONS
 
    REVENUE.  Revenue increased 44.5%, from approximately $7.8 million in the
three months ended June 30, 1997 to approximately $11.3 million in the three
months ended June 30, 1998, and increased 37.8%, from approximately $15.9
million in the first six months of 1997 to approximately $21.9 million in the
first six months of 1998. These increases resulted from an increase in case
volume of 37.7% and 30.5% for the three and six month periods respectively, due
primarily to expansion of the Company's client base and increased utilization of
the Company's diagnostic products and services by existing clients. Revenue also
increased as a result of therapeutic product co-promotion revenue.
 
                                       8
<PAGE>
    DIRECT COST OF SERVICES AND PRODUCTS.  Direct cost of services and products
increased 51.2%, from approximately $2.9 million in the three months ended June
30, 1997 to approximately $4.4 million in the three months ended June 30, 1998,
and increased 43.4%, from $5.9 million in the first six months of 1997 to $8.5
million in the first six months of 1998. These increases were due principally to
higher personnel costs and supply and distribution costs resulting from
increased case volume. Incremental costs also resulted from USS business
operations and expanded utilization of the Company's wide area network report
delivery system by the Company's clients. As a percentage of revenue, direct
expenses increased to 39.2% for the three months ended June 30, 1998 from 37.5%
for the three months ended June 30, 1997, and increased to 38.7% of revenue for
the first six months of 1998 from 37.2% for the first six months of 1997. These
increases were due primarily to USS operations costs.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased 48.6%, from approximately $4.0 million in the
three months ended June 30, 1997 to approximately $5.9 million in the three
months ended June 30, 1998, and increased 49.7%, from $7.7 million in the first
six months of 1997 to $11.5 million in the first six months of 1998. These
increases were due principally to higher personnel costs related to sales staff
and management information services personnel and professional services, and
increased provision for doubtful accounts. As a percentage of revenue, selling,
general and administrative expenses increased to 52.7% for the three months
ended June 30, 1998 from 51.2% for the three months ended June 30, 1997, and
increased to 52.6% of revenue for the first six months of 1998 from 48.4% for
the first six months of 1997.
 
    RESEARCH AND DEVELOPMENT EXPENSES.  Research and development costs decreased
18.4%, from approximately $611,000 in the three months ended June 30, 1997 to
approximately $499,000 in the three months ended June 30, 1998, and decreased
17.5%, from $1.2 million in the first six months of 1997 to $1.0 million in the
first six months of 1998. This decline was due primarily to completion of
certain external research agreements. As a percentage of revenue, research and
development expenses decreased to 4.4% for the three months ended June 30, 1998
from 7.8% for the three months ended June 30, 1997, and decreased to 4.6% of
revenue for the first six months of 1998 from 7.7% for the first six months of
1997.
 
    OTHER INCOME (EXPENSE).  Interest income decreased in the three and six
month periods ended June 30, 1998 compared to the same periods of 1997, due
principally to the decreased cash, cash equivalents and investments that
resulted from capital expenditures and an increase in accounts receivable.
Interest expense decreased in the three and six month periods ended June 30,
1998 compared to the same periods of 1997, primarily because of a decrease in
obligations under capital leases.
 
    INCOME TAXES.  The income tax provisions for the three and six months ended
June 30, 1998 of approximately $270,000 and $583,000, respectively, reflect
federal, state and local income tax expense at a 38% effective rate. No income
tax provision was recognized for the three and six month periods ended June 30,
1997 as a result of utilization of net operating loss carryforwards. Using an
effective tax rate of 38%, the recognition of tax benefits reduced the tax
provision for the second quarter of 1997 approximately $243,000 or $.02 per
share and $700,000 or $.06 per share for the six months ended June 30, 1997. As
of June 30, 1997, a valuation allowance against future benefits of net deferred
tax assets was recorded due to uncertainty regarding the realizability of such
assets through sustained profitable operations. As realizability of this asset
became more certain through a demonstrated positive earning history during 1997,
the Company reevaluated the appropriateness of recognizing these future benefits
and recorded a deferred tax asset in the fourth quarter of 1997.
 
    UROLOGY SUPPORT SERVICES.  The following table sets forth the effects of the
operating losses of USS on UroCor's reported results for the three and six month
periods ended June 30, 1998. Operations of USS are
 
                                       9

expected to continue to incur losses until the transfer of this business to an
independently financed company is completed. No gain or loss is expected on the
transfer of USS' assets.

securities, with a maturity of less than two years. As of June 30, 1998, cash,
cash equivalents and marketable investments totaled approximately $21.0 million
and the Company's working capital was approximately $38.3 million.
 
    Accounts receivable, net of allowance for doubtful accounts, totaled
approximately $18.6 million at June 30, 1998, an increase of approximately $5.0
million from December 31, 1997 or 37%. At June 30, 1998, the Company's average
number of days sales in receivables was approximately 155 compared to 142 at
December 31, 1997. The increase in accounts receivable during the six months
ended June 30, 1998 was due primarily to additional payor documentation
requirements imposed by Medicare and other third party payors which further
complicate and lengthen the billing process and systems changes necessary to
satisfy revised billing protocols by the Medicare payor. The Company believes
that it has made progress in implementing certain systems and processing changes
intended to resolve systems, documentation and related processing issues. In an
effort to reduce its average number of days sales in receivables, the Company is
continuing additional staffing, systems and process changes and is undertaking
additional initiatives intended to improve its claims and collections
efficiencies. The increase in accounts receivable is also partially attributable
to initial revenue from therapeutics co-promotion activities and USS operations.
 
    The Company monitors the collection quality of its accounts receivable
through analytical review of aging categories by payor group and collections
performance compared to historical trends. The Company maintains what it
believes to be an adequate level of an allowance for doubtful accounts through
charges to operations which are included in selling, general and administrative
expenses.
 
    Operating activities used net cash of approximately $2.0 million for the six
months ended June 30, 1998 compared to approximately $3.9 million for the six
months ended June 30, 1997. The net cash used in operating activities was
primarily the result of an approximate $5.0 million increase in accounts
receivable offset in part by net income of approximately $952,000, depreciation
and amortization of approximately $1.2 million and an approximate $417,000
increase in accounts payable.
 
    Net cash provided by investing activities was approximately $9.1 million for
the six months ended June 30, 1998 and consisted primarily of maturities of
short-term marketable investments of approximately $10.6 million and maturities
of long-term marketable investments $982,000, offset by capital expenditures of
approximately $2.3 million, and an increase in intangibles and other assets of
approximately $215,000. Net cash used in financing activities was approximately
$43,000 for the first six months of 1998, consisting primarily of principal
payments under capital leases and other indebtedness of approximately $267,000
offset by proceeds from exercise of stock options of approximately $121,000 and
proceeds of stock issuances pursuant to the employee stock purchase plan of
approximately $103,000.
 
                                       10
<PAGE>
    The Company's capital expenditures of approximately $2.3 million for the six
months ended June 30, 1998, were primarily for computer hardware and software,
furniture and fixtures and software development for the Company's information
services. Of the total amount, approximately $453,000 was related to internal
software development costs for information services. While future capital
expenditures will depend upon a number of factors, the level of expenditures is
expected to be higher than the historical level of such expenditures as the
Company expands to deliver therapeutics and information services and continues
to enhance current diagnostic services and operational capabilities. The Company
intends to finance the majority of these capital expenditures with existing cash
and investment balances.
 
    In December 1994, the Company obtained distribution rights to a therapeutic
product currently under review for marketing approval by the FDA. The total cost
of the distribution rights is $3.0 million, payable in installments based on
achievement of certain milestones by the manufacturer. The Company made an
initial payment of $750,000 in December 1994 and a second installment of
$500,000 in 1995 after the product was submitted for FDA review in April 1995.
The Company is obligated to pay an additional milestone payment of $1.75 million
if and when the product is approved by the FDA for marketing in the United
States. If the Company makes this payment in 1998, it intends to make any such
payment from existing cash and investment balances.
 
    The Company believes that its existing capital resources will be sufficient
to provide the funds necessary to maintain its present level of operations and
implement its currently planned growth strategy. However, there may be
circumstances or new business opportunities that would require additional
resources. In such event, the Company may be required to seek additional
financing and there is no assurance that the Company would be able to obtain
such financing on acceptable terms.
 
    The Company believes that it has prepared its computer systems and related
applications to accommodate date-sensitive information relating to the Year
2000. The Company expects that any additional costs related to ensuring such
systems to be Year 2000 compliant will not be material to the financial
condition or results of operations of the Company.

ITEM 2.  CHANGES IN SECURITIES AND USE OF PROCEEDS
 
    RECENT SALES OF UNREGISTERED SECURITIES
 
    During the quarter ended June 30, 1998, the Company issued a total of 28,238
shares of Common Stock for an aggregate consideration of $93,701 to various
stockholders of the Company pursuant to the exercise of certain stock purchase
warrants. None of the foregoing transactions involved underwriters. The Company
considers these securities to have been offered and sold in transactions not
involving a public offering and, therefore, to be exempted from registration
under Section 4(2) of the Securities Act of 1933, as amended.
 
    USE OF PROCEEDS:
 
    The effective date of the registration statement for the Company's initial
public offering of Common Stock and for which this use of proceeds information
is being disclosed was May 16, 1996 and the Commission file number assigned to
the registration statement was 333-3182.
 
    From the effective date of the registration statement through June 30, 1998,
the following table identifies the purposes and amounts of the net proceeds paid
directly or indirectly to others:

ITEM 5.  OTHER INFORMATION
  SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
 
    This Quarterly Report on Form 10-Q includes "forward-looking statements"
within the meaning of Section 27A of the Securities Act of 1933, as amended, and
Section 21E of the Securities Exchange Act of 1934, as amended. All statements
other than statements of historical facts included in this Report, including
without limitation, statements regarding the Company's financial position,
business strategy, products, products under development, markets, budgets and
plans and objectives of management for future operations, are forward-looking
statements. Although the Company believes that the expectations reflected in
such forward-looking statements are reasonable, it can give no assurance that
such expectations will prove to have been correct. Important factors that could
cause actual results to differ materially from the Company's expectations are
disclosed in statements set forth under "Cautionary Statements" and elsewhere in
this Report, including, without limitation, in conjunction with the
forward-looking statements included in this Report. All subsequent written and
oral forward-looking statements attributable to the Company, or persons on its
behalf, are expressly qualified in their entirety by the Cautionary Statements
and such other statements.
 
CAUTIONARY STATEMENTS
 
    RISKS ASSOCIATED WITH MANAGEMENT OF GROWTH.  Over the last several years,
the Company has experienced substantial growth and expanded its operational
capabilities. The Company is also planning to offer additional therapeutic
products and information and business management services. This growth and
expansion has placed, and will continue to place, a significant strain on the
Company's management, production, technical, financial and other resources. To
date, the Company primarily has experience in managing a diagnostics service
business. There can be no assurance that the Company will be able to manage
expansion into and operation of therapeutics, business management or information
services businesses.
 
    UNCERTAINTY RELATED TO GOVERNMENT REGULATION.  As a provider of health care
related services, the Company is subject to extensive and frequently changing
federal, state and local laws and regulations governing licensure, billing,
financial relationships, referrals, conduct of operations, purchase of existing
businesses, cost-containment, direct employment of licensed professionals by
business corporations and other aspects of the Company's business relationships.
The various types of regulatory activity affect the Company's business by
controlling its growth, restricting licensure of the business entity or by
controlling the reimbursement for services provided. The Company cannot predict
the timing or impact of any changes in such laws and regulations or their
interpretations by regulatory bodies, and no assurance can be given that any
such changes will not have a material adverse effect on the Company's financial
condition and results of operations.
 
    Existing federal laws governing federal health care programs, including
Medicare, as well as some state laws, regulate certain aspects of the
relationship between health care providers, including the Company, and their
referral sources, including physicians, hospitals and other facilities. The
Social Security Act, and the anti-kickback and self-referral rules thereunder,
prohibit providers and others from soliciting, offering, receiving or paying,
directly or indirectly, any remuneration in return for either making a referral
for a service or item and prohibit physicians, subject to certain exceptions,
from making such referrals to certain entities in which they have an investment
interest or with which they have a compensation arrangement. Violation of these
prohibitions is punishable by disallowance of submitted claims, civil monetary
penalties and criminal penalties and exclusion from the Medicare and other
federally funded programs. In recent months, the federal government has expanded
its investigative and enforcement activities in these areas. The federal
government also has become more aggressive recently in examining billing by
laboratories and other health care providers, and in seeking repayments and even
penalties based
 
                                       14
<PAGE>
on how the services were billed (e.g. the billing codes used), regardless of
whether carriers had furnished clear guidance on this subject.
 
    In July 1998, the Company received a Civil Investigative Demand (the "CID")
from the United States Department of Justice (the "DOJ") concerning allegations
that the Company may have submitted false claims in connection with bills for
services submitted to Medicare and other federal insurance programs. The CID
requires the Company to produce certain documents to the DOJ. The Company
intends to cooperate fully with the DOJ with respect to this investigation.
Although the Company seeks to structure its practices to comply with all
applicable laws, and management believes its practices are in compliance, no
assurances may be given regarding the resolution of this matter, and the Company
is unable to predict its impact, if any, on the Company. If the DOJ were to
pursue and prevail on matters that may arise from this investigation, any
significant recoupment of funds or civil or criminal penalty or exclusion from
the Medicare program potentially resulting from such proceedings would have a
material adverse effect on the Company.
 
    The Company's diagnostic laboratory operations currently are required to be
certified or licensed under the federal Clinical Laboratory Improvement Act of
1976, as amended in 1988, the Medicare and Medicaid programs and various state
and local laws. In some instances, the Company is also subject to licensing or
regulation under federal and state laws relating to the handling and disposal of
medical specimens, infectious and hazardous waste and radioactive materials, as
well as to the safety and health of laboratory employees. The sanctions for
failure to comply with these regulations may include denial of the right to
conduct business, significant fines and criminal penalties. The loss of a
license, imposition of a fine or an increase in the complexity or substantive
requirements of such federal, state and local laws and regulations could have a
material adverse effect on the Company's financial condition and results of
operations.
 
    While the Company currently knows of no plans that the FDA has to require
FDA approval of assays developed by laboratories for in-house use, the FDA has
in the past considered drafting guidelines for such regulation. If in the future
the FDA were to issue guidelines for the clinical laboratory market sector, such
guidelines might require the Company to meet certain FDA medical device approval
requirements for the Company's in-house assays. Such regulations, if enacted in
a way that affects the Company, would increase the cost of development and
approval of new products, slow their introduction to the market and could have a
material adverse effect on the Company's financial condition and results of
operations. Additionally, in a recent rule, the FDA stated that in some
circumstances involving in-house assays, laboratories will be required, upon
effectiveness of the rule, to indicate that the assay has not been cleared by
the FDA. There can be no assurance that such disclosure will not have an adverse
impact on reimbursement.
 
    The FDA currently regulates a number of the products which the Company
purchases from third parties for use in its diagnostic services. The
manufacturers of such products are responsible for compliance with FDA
regulations relating to such products. There can be no assurance, however, that
action by the manufacturers or by the FDA would not impair the Company's ability
to obtain and offer certain services. The unavailability of certain services and
materials used in the Company's diagnostics business would have a material
adverse effect on the Company's financial condition and results of operations.
 
    The FDA regulates products licensed or otherwise acquired from third parties
and distributed or marketed by the Company. The manufacturers of such products
are responsible for compliance with the approval and marketing regulations of
the FDA. The ability of such third parties to address their FDA regulatory
issues is outside the Company's control. There can be no assurance that the
failure of such third parties to address their FDA regulatory matters adequately
will not have a material adverse effect on the Company's results of operations
and financial condition.
 
    Although the Company's existing and proposed information services products
currently are not subject to regulation by the FDA, the FDA could determine in
the future that the predictive applications of these products are deemed to be
medical devices subject to FDA regulation. In that event, the Company
 
                                       15
<PAGE>
could experience delays in developing and marketing new services and increases
in research and development costs.
 
    UNCERTAINTIES RELATED TO THIRD-PARTY REIMBURSEMENT; POTENTIAL HEALTH CARE
REFORM.  The Company typically bills governmental programs such as Medicare and
other third-party payors such as private insurance and managed care plans for
its products and services. Such third-party payors are increasingly negotiating
prices with the goal of lowering reimbursement rates, which may result in lower
profit margins for the Company. Reimbursement rates have been established for
most but not all of the services performed by the Company. The Company cannot
collect from Medicare or other third-party payors for services that those payors
have not approved for reimbursement. There can be no assurance that the Free/
Total PSA assay currently provided by the Company or any other products under
development will be approved for reimbursement by Medicare or other third-party
payors. Furthermore, Medicare and other third party payors have, on occasion,
ceased reimbursement when certain tests are ordered for patients with certain
diagnoses while maintaining reimbursement when those tests are ordered for other
diagnoses deemed appropriate by the carrier. This practice has recently become
more prevalent with respect to Medicare. Medicare may retroactively audit and
review its payments to the Company and may determine that certain payments for
services must be returned. From time to time, the public and federal government
focus significant attention on reforming the health care system in the United
States. In 1997, Congress enacted the Balanced Budget Act of 1997 that effected
numerous changes to the Medicare and Medicaid programs that could affect health
care providers, including clinical laboratories. The 1997 act also revised the
resource-based relative value scale system that could affect health care
providers that offer physician pathology services. These 1997 changes and any
future changes in Medicare and other third-party payor reimbursement which may
result from health care reform or deficit reduction legislation will likely
continue the downward pressure on prices. A number of other legislative
proposals have been introduced in Congress and state legislatures in recent
years that would effect major reforms of the health care system and otherwise
reduce health care spending. Because of the uncertainties surrounding the
nature, timing and extent of any such reimbursement changes, audits and reform
initiatives, the Company is unable to predict the effects of any such
matterschanges on the Company.
 
    UNCERTAINTIES RELATED TO ACCOUNTS RECEIVABLE.  In recent years, the
Company's Medicare intermediary and certain other third-party payors have
increased the amount of time between their receipt of claims for reimbursement
and payment to the Company as well as significantly increased the documentation
and information requirements, further complicating the billing process. At June
30, 1998, the Company's average days sales in receivables was approximately 155,
compared to 142 at December 31, 1997. Such changes have resulted in the
Company's accounts receivable increasing at a rate greater than revenue growth
and, therefore, have affected the Company's cash flow from operations. There can
be no assurance that these payors will not further modify their payment
practices and impose other requirements, which could have a material adverse
affect on the Company's financial condition and results of operations. In
addition, as a result of the increase in accounts receivable, the Company's
allowance for doubtful accounts has increased. Although the Company maintains
what it believes to be an adequate reserve for doubtful accounts, there can be
no assurance that the Company will not be required to provide additional
reserves, which could have an adverse affect on the Company's results of
operations.
 
    RISKS RELATED TO UROLOGY SUPPORT SERVICES.  The Company currently provides
limited business management services, primarily accounts receivable management,
to selected urologist clients, through the Company's USS business. The Company
recently decided to pursue the transfer of the business and assets of USS to an
independently financed company in which UroCor intends to retain a minority
interest. The Company has made capital investments and incurred other expenses
to develop the infrastructure and systems for USS. There are a number of factors
outside the Company's control which may delay or hinder the transfer of USS. The
operating losses of USS have had a negative impact on the Company during this
initial development phase and are expected to continue through the completion of
the transfer of the business. The Company anticipates no gain or loss on the
transfer of the business, however, since a
 
                                       16
<PAGE>
transaction has not yet been negotiated, there can be no assurance that the
Company will be able to complete the transfer of this business, or if effected,
that the terms of such transaction will allow the Company to recover its
investment in the assets of USS. In addition, if a transfer of the business is
not completed, the Company may incur losses upon disposition that could have a
material adverse effect on the Company's results of operations.
 
    UNCERTAINTIES RELATED TO INVESTMENTS IN DISEASE MANAGEMENT INFORMATION
SYSTEMS.  The Company has been and expects to continue investing in the
development of information-based capabilities and services which it plans to
introduce in the future related to the clinical management of urologists'
patients and the business management of their practices. The Company has
developed and introduced, on a limited basis, disease outcomes reporting
capabilities in one disease state. Further development and delivery of these new
services will require substantial additional investment and represents an
expansion of the type of services the Company presently provides to urologists.
There can be no assurance that any future revenues directly or indirectly from
these services will be sufficient to cover or otherwise justify the costs of
development and introduction.
 
    UNCERTAINTY OF ACCESS TO CAPITAL.  The Company's growth since 1991 has
required, and any future growth will require, significant amounts of working
capital. Although the Company believes that existing capital resources will be
adequate to fund its present level of operations and implement its currently
planned growth strategy, there may be circumstances or new business
opportunities that would require additional resources. In such event, the
Company may be required to seek additional financing, and there is no assurance
that the Company would be able to obtain such financing on acceptable terms.
 
    DEPENDENCE ON CERTAIN PRODUCT LINES.  A significant portion of the Company's
revenue has been, and is expected to continue to be, dependent upon the
Company's prostate tissue analysis and bladder cellular analysis product lines.
Any negative event related to these product lines, such as increased
competition, pricing pressures, reimbursement changes and clinical or
technological obsolescence, would have a material and adverse effect on the
Company's financial condition and results of operations.
 
    NO ASSURANCE OF SUCCESSFUL ACQUISITION OF DISTRIBUTION RIGHTS FOR
THERAPEUTIC PRODUCTS.  Through its UroTherapeutics Group, the Company is
developing a therapeutic products business. The Company currently has acquired
distribution or co-promotion rights for three therapeutic products. The Company
has recently begun to co-market two of the therapeutic products, and there can
be no assurance that the Company's efforts will be successful. There can also be
no assurance that the Company will be successful in negotiating any additional
distribution or other agreements related to therapeutic products in the future.
 
    UNCERTAINTIES RELATED TO THE FDA APPROVAL OF THERAPEUTIC PRODUCT.  The
Company has a distribution agreement with BioChem Vaccines, Inc. ("BioChem"), a
subsidiary of BioChem Pharma, Inc., for a therapeutic product for use in
treating certain types of bladder cancer. Pursuant to the distribution
agreement, BioChem is responsible for obtaining approvals from the FDA for
marketing the therapeutic product in the United States. In April 1995, BioChem
filed its initial applications with the FDA. In April 1996, the FDA advised
BioChem that its application was not approvable and requested additional data
regarding certain aspects of manufacturing and testing of the product, which
BioChem filed with the FDA through an amended application in August 1996.
Following a May 1997 site inspection of BioChem's manufacturing facilities and
operations, the FDA issued a report on FDA Form 483 indicating that additional
requirements related to BioChem's facility, process and documentation were
required before these applications could be approved. Although BioChem has
advised the Company that it believes it can satisfy the FDA requirements, there
can be no assurance that approval will be obtained.
 
    RISKS ASSOCIATED WITH DEVELOPMENT OF DATABASE.  The confidentiality of
patient medical records is subject to substantial regulation by the state and
federal governments. State and federal laws and regulations govern both the
disclosure and the use of confidential patient medical record information.
 
                                       17
<PAGE>
Legislation governing the dissemination and use of medical record information is
being proposed continually at both the state and federal levels. For example,
the Health Insurance Portability and Accountability Act of 1996 requires the
Secretary of the United States Department of Health and Human Services to
recommend legislation or to promulgate regulations governing privacy standards
for individually identifiable health information. Additional legislation may
require that holders or users of confidential patient medical information
implement measures to maintain the security of such information and may regulate
the dissemination of even anonymous patient information. Physicians and other
persons providing patient information to the Company are also required to comply
with these laws and regulations. If a patient's privacy is violated, or if the
Company is found to have violated any state or federal statute or regulation
with regard to the confidentiality, dissemination or use of patient medical
information, the Company could be liable for damages, or for fines or penalties.
The Company believes that it complies in all material respects with all
applicable state and federal laws and regulations governing the confidentiality,
dissemination and use of medical record information. However, there can be no
assurance that differing interpretations of existing laws and regulations or the
adoption of new laws and regulations would not have a material adverse effect on
the ability of the Company to obtain or use patient information which, in turn,
could have a material adverse effect on the Company's plans to develop and
market its urology disease information database and related treatment. The
Company intends to continue to monitor and review the interpretation and
enactment of laws and regulations which affect the Company's plans to develop
and market its urology disease information database. In addition, the American
Medical Association (the "AMA") has issued an opinion to the effect that a
physician who does not obtain a patient's consent to the disclosure of the
patient's medical record information violates the AMA's ethical standards. While
the AMA's opinions are not law, they may influence the willingness of physicians
to obtain patient consents or to disclose patient medical information to the
Company and thus could have a material adverse effect on the Company's plans to
develop and market its urology disease information database.
 
    UNCERTAINTIES RELATED TO MANAGED CARE.  Managed care organizations are
gaining increasing control over access to health care and payment for an
increasing number of patients with urological diseases. There can be no
assurance that the Company will be able to maintain its existing contracts with
managed care organizations or that it will be able to obtain additional
contracts with such organizations in the future which could preclude the Company
from serving large groups of patients in certain markets. The Company has
experienced increasing pricing pressure from managed care organizations, and
such pressure is expected to continue. There can be no assurance that such
pricing pressure and any contract restrictions will not have a material adverse
effect on the Company's financial condition and results of operations.
 
    NO ASSURANCE OF ACCESS TO AND DELIVERY OF NEW DIAGNOSTIC TECHNOLOGY.  The
markets for the Company's diagnostic products and services are characterized by
rapidly changing technology, frequent new product introductions and enhancement
and, therefore, rapid product obsolescence. There can be no assurance the
Company will be able to identify new products, trends or opportunities, develop
and bring to market new products, respond effectively to new technological
changes or product announcements by others, develop or obtain access to advanced
materials and technologies, or receive commercial acceptance for its products.
 
    UNCERTAINTIES ASSOCIATED WITH COMPETITIVE PRESSURES.  The industry in which
the Company's diagnostics business operates is characterized by intense
competition with many different types of competitors including specialty
laboratories, diagnostic kit and instrumentation manufacturers, local and
regional pathology services, hospital laboratories and large general reference
clinical laboratories. Many of the Company's competitors are significantly
larger and have significantly greater financial, technical and administrative
resources than the Company; many also have long established relationships with
the Company's current and prospective customers and with managed care
organizations. There can be no assurance that the Company will be able to
compete successfully with such entities in the marketing of products and
services and in the acquisition of new technologies.

    POTENTIAL FLUCTUATIONS IN OPERATING RESULTS.  The Company's quarterly and
annual operating results are affected by a wide variety of factors, many of
which are outside the Company's control, which have in the past and could in the
future materially and adversely affect revenue, operating expenses and income.
These factors include seasonality, the quantities and timing of specimens
received, competitive pricing pressures, reimbursement changes, availability and
cost of diagnostic supplies, availability and cost of logistic services, changes
in the mix of products sold, timing and costs of new product and technology
introductions by the Company or its competitors, retention and expansion of the
sales force and timing of payments from Medicare and other third-party payors.
The need for continued investment in research and development and expansion of
its product lines could limit the Company's ability to reduce expenses quickly.
As a result of these factors, the Company's operating results may continue to
fluctuate in the future.
 
    YEAR 2000 RISKS.  Although the Company does not expect to incur significant
expenditures to address year 2000 issues, there can be no assurance that this
will be the case. Additionally, the ability of third parties with whom the
Company transacts business to address their year 2000 issues adequately is
outside the Company's control. There can be no assurance that the failure of the
Company or such third parties to address their respective year 2000 issues
adequately will not have a material adverse effect on the Company's results of
operations and financial condition.
