PART I.

ITEM 1. BUSINESS

Overview

Specialty Laboratories is a leading hospital-focused clinical laboratory, performing highly advanced, clinically useful testing services for hospitals,
laboratories and physician specialist communities nationwide. We believe we offer the most comprehensive menu of esoteric assays in the industry, many of which have been developed through our internal
research and development efforts. Esoteric assays are complex, comprehensive or unique tests used to diagnose, evaluate and monitor patients. These assays are often performed by highly skilled
personnel using sophisticated instruments and are therefore offered by a limited number of clinical laboratories.

Our
primary customers are hospitals, independent clinical laboratories and physicians. We have aligned our interests with those of hospitals, our fastest growing client segment, by not
competing in the routine test market that provides them with a valuable source of revenue. We educate physicians on the clinical value of our assays through our information-oriented marketing
campaigns. Our technical, experienced sales force concentrates on the hospitals and independent laboratories that serve as distribution channels for physician assay orders. We use our advanced
information technology solutions to accelerate and automate electronic assay ordering and results reporting with these customers.

We
are a California corporation and were incorporated in 1975 under the name Clinical Immunology Laboratories, Inc. In 1985 we changed our name to Specialty
Laboratories, Inc. Our principal offices are located at 2211 Michigan Avenue, Santa Monica, California 90404.

We
maintain a World Wide Web site at www.specialtylabs.com. The information on our web site should not be considered part of this Report.

Clinical Laboratory Industry

Clinical laboratory testing is critical to the delivery of quality healthcare to patients. Laboratory tests are used by physicians to assist in the detection,
diagnosis, evaluation, monitoring and treatment of diseases and other medical conditions through the measurement and analysis of chemical and cellular components in blood and other bodily fluids and
tissues. Clinical laboratory tests are frequently ordered as part of physician office visits and hospital admissions. Most clinical laboratory tests ordered are considered routine and can be performed
by most clinical laboratories. Esoteric assays generally require more sophisticated instruments and highly skilled personnel, and are typically outsourced to independent clinical laboratories that
specialize in such assays.

1

---



Routine tests are ordered by physicians and may be performed by clinical laboratories through the use of standardized prepared kits manufactured by diagnostic
companies. Routine tests include procedures in the areas of blood chemistry, hematology, urine chemistry, bacteriology, tissue pathology and cytology. Commonly ordered individual routine tests include
red and white blood cell counts, Pap smears, blood cholesterol level tests, urinalyses and pregnancy tests. Because routine tests often employ mass-produced commercial kits, which can be
performed with limited training, they are usually more competitively priced than esoteric assays. Although we can perform routine tests, we do not compete in the routine segment of the clinical
laboratory industry.



Esoteric assays are typically ordered when a physician requires additional information to complete a diagnosis, establish a prognosis or to choose and monitor a
therapeutic regimen. Esoteric assays include procedures in the areas of molecular diagnostics, protein chemistry, cellular immunology and advanced microbiology. Commonly ordered esoteric assays
include viral and bacterial detection assays, drug therapy monitoring assays, autoimmune panels and complex cancer evaluations. In contrast to routine tests, esoteric assays generally require
sophisticated instruments and materials and highly skilled personnel to perform and analyze results. Consequently, esoteric assays are generally priced substantially higher than routine tests. Because
it is not cost-effective for most hospitals, independent laboratories or physician office laboratories to develop and perform a broad menu of esoteric assays, these assays are generally
outsourced to independent clinical laboratories that specialize in performing these complex assays.

Our Competitive Advantages



We currently offer a comprehensive menu of more than 2,500 esoteric assays, which we believe is greater than the esoteric offering of any other clinical
laboratory in the United States. The breadth of our assay menu distinguishes us from large independent laboratories which typically offer only a select number of esoteric assays, and from smaller
niche laboratories focused on specific clinical areas. Our comprehensive menu allows our customers to rely on us for substantially all of their esoteric testing needs.

Many
of our assays were developed through our R&D efforts and are unique to us. We have historically leveraged our expertise in molecular diagnostics and applied it to high growth
segments of the esoteric testing industry including fields of medicine such as infectious disease, gastroenterology, oncology, endocrinology, and cardiology. We believe that we have developed one of
the most extensive menus of assays in these attractive growth areas.

Beginning
in 2000, we broadened our assay development effort and initiated technology partnerships with leading biotechnology companies. Rather than rely solely on internal R&D, we work
closely with these companies to incorporate their intellectual property and technological advances into commercially
viable clinical applications. We believe that our expertise in assay development and commercialization makes us an excellent partner to biotechnology companies with emerging technologies.

We
market and sell many of our esoteric assays under trademarks such as GenotypR, our assays for predicting resistance to HIV, and ANAlyzer®, our assays used to
help diagnose complex autoimmune disorders. For the year ended December 31, 2002, approximately 34% of our net revenue was derived from branded esoteric assays. We believe these branding
efforts have contributed to

2

---

increased market share and premium pricing as physician specialists often continue to rely on our products, even after the introduction of a similar assay by a competitor.



Our predominant focus on the esoteric segment of the clinical laboratory industry allows us to align our interests with those of our hospital customers. Many
hospital-based laboratories attempt to increase revenue by marketing and performing routine tests for physicians, commonly known as laboratory "outreach." Hospitals compete with national independent
clinical laboratories for these routine tests. We believe that hospitals are more inclined to refer their esoteric testing to independent clinical laboratories that do not compete with them for
routine tests.

We
enhance our hospital customers' outreach capabilities by marketing our comprehensive menu of esoteric assays as a complement to their routine testing. We also emphasize our laboratory
outreach advisory services that help hospitals market their outreach laboratories to their physician community. These advisory services include information technology tools that will help connect
hospital laboratories to physician offices. This connectivity improves communications and logistics between the hospital laboratories and their physician clients. We potentially benefit by receiving
more esoteric assay referrals from these hospitals as they may receive more routine and esoteric laboratory referrals from their physicians. Ultimately, we believe this strategy enhances our access to
esoteric assays that might otherwise be referred to our competitors.



We offer our customers information technology that accelerates and automates assay ordering and results reporting. We believe that many of our competitors still
manage a large portion of their order and results transactions manually. In 1998, approximately 40% of our transactions were transmitted electronically, principally through direct
computer-to-computer links with a small number of our largest customers. At that time, we began a customer-focused information technology initiative to efficiently utilize the
Internet. This project reduced the implementation time and cost of providing electronic links
to large and small customers alike. This led to substantial cost savings, fewer data entry errors, improved ease of assay ordering and shorter turn-around time for results reporting.
Today, more than 80% of our transactions with our customers are conducted electronically. Furthermore, we believe that our customer-focused information technology offerings include a number of
features that cannot be easily duplicated.



We focus our R&D efforts on introducing novel assays, improving existing technologies and enhancing our reputation as an industry leader in new assay development.
As an example, in 1988, we believe we were the first commercial laboratory to capitalize on the use of polymerase chain reaction technology, or PCR, by introducing and making PCR tests for HIV widely
available. In emergency situations, we endeavor to develop new assays within a shorter period of time. For example, in 1999, within two weeks of learning about the outbreak of West Nile Fever in the
New York metropolitan area, we developed a breakthrough detection assay and worked with the Centers for Disease Control and Prevention to notify physicians that this assay was available to monitor the
spread of the virus causing the outbreak.

Our
R&D expertise also places us in a position to collaborate with biotechnology companies to commercialize their proprietary assays, methods and technologies. For example, in 2001, we
signed an agreement with VIRalliance, a subsidiary of BioAlliance Pharma of Paris, France, to perform testing for resistance to HIV therapy using their procedures for phenotyping. With this exclusive
technology transfer agreement, we are currently the only full-service reference laboratory in the United States to

3

---

perform drug resistance testing by phenotyping. In 2002, we worked on an exclusive basis with research laboratories at UCLA to introduce a commercial assay for genetic resistance to
Gleevec®, the breakthrough new therapeutic for chronic myelogenous leukemia.



We regularly evaluate our operations for process improvement opportunities and have made substantial investments in advanced process automation projects. In the
second half of 2000, we began the implementation of our automated specimen management system known as TARO. This high speed sorting system reduces the potential for human error, increases
the productivity of laboratory staff and shortens turn-around time within the laboratory. The TARO system became fully operational in the first quarter of 2001 and we believe
the TARO system has boosted our laboratory productivity. As part of our continuing emphasis on process improvements, we have developed an ancillary system to TARO that is
designed for high-throughput, precise division of specimens, a process commonly known as aliquoting. This robotic aliquoting system, designated as HANA, became operational in
second half of 2002. Due to the precision of this automation, HANA had an immediate impact by identifying patient
samples containing insufficient specimen volume for tests to be performed, and thus lowering the number of patient samples that had to be handled.

Our
research orientation affords us the flexibility to choose between standardized prepared kits, other available testing technologies, and our own internally developed methodologies
depending on cost, quality and market preference. This flexibility provides us the opportunity to gain additional operating efficiencies, as we are not solely dependent on platforms designed for
specific commercial kits.

Acquisitions

On February 20, 2001, we acquired certain assets and liabilities of BBI Clinical Laboratories, Inc. (BBICL), a Massachusetts corporation, for
$9.5 million in cash. The purchase price was allocated to the assets acquired and liabilities assumed based on the estimated fair values as of the purchase closing date. The acquisition
agreement provided for a reduction of the purchase price if certain performance measurements (i.e., asset delivery, client retention and accounts receivable collections) were not achieved. A
subsequent evaluation of these performance measurements resulted in the return of $358,000 by BBICL to us in December 2001. Of the $9.1 million net purchase price, approximately
$5.9 million was allocated to goodwill and $1.9 million was allocated to the customer list. The acquisition has been accounted for under the purchase method of accounting. The operating
results of BBICL are included in the financial statements from the acquisition date.

Products and Services

We perform all of our testing services at our laboratory facility in Santa Monica, California. We do not have patient service centers and therefore do not obtain
specimens directly from patients. Typically, our customers collect a patient's specimen and forward it directly to our laboratory facility. Our laboratory facility accepts specimens 24 hours a
day, seven days a week, 365 days a year. Most specimens are analyzed and the results are reported within 48 hours of receipt.

We
currently offer what we believe is the most comprehensive menu of esoteric assays in the industry. Following a business evaluation of our testing menu in the second half of 2002 and
the resultant elimination of certain low-volume or clinically redundant services, the menu currently consists of more than 2,500 esoteric assays. The breadth of our assay menu
distinguishes us from large independent laboratories that typically offer only a select number of esoteric assays and from smaller niche laboratories focused on specific clinical areas. Our
comprehensive menu allows our customers to rely on us for substantially all of their esoteric testing needs. Esoteric assays are typically ordered when

a physician requires additional information to complete a diagnosis, establish a prognosis, or to choose and monitor a therapeutic regimen.

Many
of our assays were designed by our R&D team and are unique to us. We have historically leveraged our expertise in molecular diagnostics and applied it to high growth segments of the
esoteric testing industry including fields of medicine such as infectious disease, gastroenterology, oncology, endocrinology and cardiology. Molecular diagnostic assays comprised approximately 32% of
our net revenue for the year ended December 31, 2002. Broadly speaking, molecular diagnostics includes all test procedures incorporating or identifying DNA- or RNA-based
targets. This includes assays detecting the presence of a gene for a given disorder such as cystic fibrosis and assays examining DNA to help predict a patient's response to different drugs, such as
HIV resistance assays. These assays can also detect viruses by identifying their unique genetic profile. We believe that we have developed one of the most extensive menus of molecular diagnostics
assays. As a result of this expertise, we intend to develop novel, first-to-market assays and capture additional revenues by capitalizing on recent advances in the accumulated
knowledge of the human genome.

Our
assays for Hepatitis B and C and cardiovascular disease illustrate our ongoing application of advanced diagnostic techniques to diseases affecting a large or growing segment of the
population. Hepatitis B and C together affect approximately five million Americans, including three million with active infections. In this market, we offer approximately 50 assays using molecular
diagnostics and other techniques to help physician specialists diagnose and monitor therapy effectiveness. In the cardiovascular disease market, we offer more than 45 assays designed to help
physicians identify high-risk individuals. These assays help identify genetic mutations and infectious, metabolic and autoimmune markers all associated with increased cardiovascular risk.

We
market and sell many of our assays under trademarked names such as GenotypR and Phenoscript, our assays for predicting resistance to HIV, and
ANAlyzer®, our assays used to diagnose complex autoimmune disorders. For the year ended December 31, 2002, approximately 34% of our net revenue was derived from branded esoteric
assays. We believe these branding efforts have contributed to increased market share and premium pricing as physician specialists often continue to rely on our products, even after the introduction of
a similar assay by a competitor.

While
we offer more than 2,500 esoteric assays, 30 of our esoteric assays currently account for a substantial portion of our net revenue. These assays, on a net revenue basis, accounted
for approximately 45% of our net revenue for the years ended December 31, 2002 and 2001. For more information, see "Risk FactorsWe rely on a few assays for a significant portion of
our net revenue. If demand for these assays were to weaken for any reason, our net revenue would decrease."

Marketing and Sales



Our marketing and sales organization consists of a staff of 9 marketing professionals and approximately 50 technical representatives and sales managers. Sales
representatives principally focus on large accounts including hospitals or independent laboratories throughout the United States, with a small percentage of their time spent selling directly to
physician specialists. Currently two sales representatives focus primarily on national accounts and group purchase organizations. We continually educate our sales representatives on the technical and
clinical merits of our products. We use traditional sales meetings, technical on-line sales training and in-the-field training to ensure our sales representatives
are properly informed about all areas of our product lines and selling processes.

5

---



Our core marketing strategy is centered around our hospital clients. We continue to provide our clients with tools, such as customized turn-around
time reports, that make it easier to use Specialty as their reference laboratory. In the IT area, we intend to continue our development of our next generation web-based order entry system,
Outreach Express®, providing hospitals with a tool for growing their physician-based business. With a renewed focus on service, we are also promoting the value that our service
enhancements afford each facility.

We
intend to continue educating physician specialists on the clinical value of our assays through research publications, print advertisement, direct mail, and the Internet. These
targeted marketing tools are designed to be effective while minimizing the need for direct physician contact by our sales representatives. We actively pursue publication of our scientific research in
peer-reviewed journals and have had more than 800 articles published. We have printed and regularly update ten widely-used, proprietary reference manuals on the use and
interpretation of our assays, focusing on medical specialties such as infectious disease, gastroenterology, oncology and cardiology. We present our research at scientific meetings and we exhibit at
nearly 60 national and regional conferences throughout the year. Our web site is another vehicle for educating physicians about our assays and contains our entire directory of services,
on-line technical materials and links to other medical sites that support the role of esoteric assays in effective diagnosis and treatment of diseases.



We concentrate our selling efforts on the management teams of hospitals and other independent laboratories that serve as distribution channels for physician assay
orders. These management teams typically include laboratory managers, pathologists, finance, and information technology personnel. To a lesser extent, we also call directly on physician specialists
who create the demand for our assays.

In
connection with our hospital-focused strategy, we concentrate on increasing the volume of testing we perform for existing clients. Our goal is to grow the percentage of total testing
these existing clients send to us, so that we become their primary provider of esoteric reference testing. Our marketing department provides our sales representatives with a comprehensive database
containing pertinent information on hospital information technology systems, key contacts and existing competition. Sales representatives are trained to find new market opportunities and provide
solutions to address unmet customer needs, which may include outreach support, information technology products, assay information and general servicing.

We
also facilitate hospital sales through affiliations with group purchasing organizations. Although hospitals participating in group purchasing organizations are not obligated to use
the group purchasing organization contracted laboratory for their reference testing, a group purchasing organization contract may provide us with access to additional hospital business. For further
discussion of our group purchasing organization relationships, see "CustomersHospitals" below.



Our customers include hospitals, independent laboratories, physician specialists and other medical providers. The following table provides percentages of our net

Hospitals accounted for approximately 61% of our net revenue for the year ended December 31, 2002. Of the estimated 5,000 hospitals to which we target our
services, approximately 2,000 are currently our customers. We are a primary provider of esoteric reference laboratory testing services for approximately 250 of these hospital customers.

Many
of our hospital customers are part of one or more group purchasing organizations which typically pool independent hospitals together to negotiate for pricing and services, including
prices for laboratory tests. Generally, hospitals participating in group purchasing organizations are not obligated to use the group purchasing organization contracted laboratory for their reference
testing, and many hospitals are affiliated with multiple group purchasing organizations. We are currently under contract with the following voluntary group purchasing organizations:

Each
of our agreements with group purchasing organizations provide for discounted fee structures for our assays including capped price increases. Some of these contracts provide
additional discounts for certain assays. Most of these contracts also provide that we pay a quarterly administrative fee to the group purchasing organization.



For the year ended December 31, 2002, independent laboratories represented approximately 29% of our net revenue. Regional and national independent
laboratories together comprise more than 1,300 accounts in the independent laboratory segment that we can potentially serve. Regional independent laboratories typically receive test requests directly
from physicians. Regional laboratories will perform the routine tests and outsource the esoteric assays to an esoteric national laboratory like us. Although other national independent laboratories
perform some esoteric testing, they may outsource to us any esoteric assays they are unable to perform and also honor requests from physician specialists who specify that we perform particular assays.

In
October 1999, we entered into a multi-year agreement with Unilab Corporation pursuant to which it agreed to refer to us, until the agreement expired in
October 2002, at least 90% of the esoteric laboratory services it outsources each year or, in the event of a change of control of Unilab or the purchase by Unilab of a licensed clinical
laboratory with a test menu materially broader than that of Unilab, at least $800,000 of esoteric laboratory services per month. As announced in April 2002, and completed in February of 2003,
Unilab was acquired by Quest Diagnostics, Inc. Following the expiration
of our multi-year agreement with Unilab, in October 2002, we experienced a significant decline in the test volumes sent to us from Unilab. We entered into a new agreement with
Unilab in October 2002 that allows for an orderly transfer and wind-down of work in light of the acquisition of Unilab by Quest. As part of this wind-down, in
March 2003 Unilab provided us notice that it would stop sending us certain tests covered under the new agreement. For the year ended December 31, 2002, Unilab represented approximately
10% of our net revenues.



For the year ended December 31, 2002, physician specialists comprised approximately 8% of our net revenue and represented approximately 800 accounts.
Currently, there are more than 200,000

7

---

physician specialists in the U.S., of which approximately 120,000 fall directly into our targeted medical specialties. Although they account for a small percentage of direct net revenue, physician
specialists can influence the clinical acceptance of an assay, and can specifically influence laboratory choice by specifying that a particular specimen be sent to us or by ordering a particular assay
that is unique to or branded by us.

Our
remaining net revenue is derived primarily from clinical trials drug development testing. Our clinical trials business focuses primarily on pharmaceutical and biotechnology companies
trying to develop new drugs. We offer these companies customized assays to aid in the study and development of new therapeutic agents and applications. Testing services for the drug development market
comprised approximately 2% of our net revenue for the year ended December 31, 2002. We believe that companies may choose us for their drug development testing because of our experience in
developing new assays.

Payors, Billing & Reimbursement

We typically bill our customers, such as hospitals or other independent laboratories, directly. In some instances, we bill the individual patient directly or
third party payors such as Medicare, Medicaid or private insurance. The following table illustrates our payor mix as a percent of net revenue:

All
of our billing and payment functions are executed through a centralized computerized billing system. Our web-based DataPassportMD® product collects required
billing information for Medicare, Medicaid and other insurance reimbursements at the time of assay ordering.

Information Technology

We have invested significant resources into proprietary information technology that accelerates and automates test ordering and results reporting with our
customers. These information technology products, branded as DataPassport® and Outreach Express®, are designed to take advantage of Internet-based technologies. Although some
customers only require a simple electronic transfer of orders and results, others are seeking solutions to help them connect disparate systems or connect physician practices associated with laboratory
outreach programs. Compared to other currently available information technology applications designed to have similar functionality, we believe all of our information technology products have the
advantages of faster system implementation, greater ease of
use and lower customer costs. We have also invested resources designed to provide patient confidentiality and compliance with governmental regulations regarding data privacy and security.

In
1998, approximately 40% of our transactions were transmitted electronically, principally through direct computer-to-computer links with a small number of our
largest customers. At that time, we began a customer-focused information technology initiative to effectively utilize the Internet and provide electronic connectivity to large and small customers
alike. Today, more than 80% of the transaction volume with our customers is transmitted electronically.

Our
current offering of information technology products include DataPassport® client interface module, DataPassportMD® and Outreach Express®. We
believe that our evolving suite of information technology products will continue to lead to greater customer loyalty, a reduction of data entry errors, acceleration of test ordering and results
reporting, and substantial cost savings. The security features on our information technology products are intended to protect the confidentiality of patient information in accordance with state and
federal law.



Because of the volume of assays ordered, our larger accounts require a direct connection between us and their Laboratory Information System, also known as LIS, to
streamline the assay ordering and results reporting process. Traditional methods of connecting directly with a customer's LIS system are generally cumbersome and require a significant amount of time
to implement because such links are dependent on the involvement of a third party LIS vendor to assist in software programming. Our DataPassport® client interface module greatly decreases
this implementation lag-time and bypasses the need for the LIS vendor by emulating the hospital's LIS data format. Consequently, our client interface module may be operative within six to
eight weeks, as compared with six months or more for traditional computer-to-computer links. The client interface module also provides additional features not available with
traditional computer-to-computer links, such as assay and physician utilization reports, and a flexible architecture that can accommodate future expansion and require fewer
internal customer resources.



We believe this product is the most widely used web-based laboratory order entry and resulting system in hospitals today. Currently, approximately
1,200 of our customers are using DataPassportMD®. One of the key benefits of DataPassportMD® is that it permits electronic order entry and results reporting for
our smaller volume customers, and can be used alone or as part of a flexible architecture. DataPassportMD® does not require any specialized hardware at the user site, making implementation
almost immediate. We have added unique features to enhance the order entry and results reporting screens, including on-line access to our proprietary "use and interpretation of tests"
books, graphical reporting features and extensive report generation tools for monitoring test or customer usage. We believe this product is user friendly, requiring only simple training for system
users and on-site data maintenance.



We anticipate that our hospital and independent laboratory customers wishing to grow their testing business will use Outreach Express®. This product
is intended to allow these customers to connect with physicians directly over the Internet. Outreach Express® uses the functionality of DataPassportMD® and is hosted through
our servers. The advantages to these customers are that no specialized hardware must be purchased and the entire information technology product can be supported outside their laboratory. We designed
Outreach Express® to enable physicians to access assay results from hospitals and independent laboratories electronically and, thus, more quickly than receiving such information manually.
We believe that Outreach Express® provides these customers with a competitive advantage in their respective market. By aiding these customers in their outreach efforts, we believe that
they will continue to utilize our services. We currently have Outreach Express® in production at eleven sites.

Process Automation

We have implemented an automation system known as the Total Accessioning Re-Organization system, or TARO, for our pre- and
post-analytical specimen management. This high speed automated sorting system reduces the potential for human error, increases the productivity of laboratory staff and decreases overall
turn-around time within the laboratory. We began implementation of TARO in the second half of 2000 and it became fully operational in the first quarter of 2001. Specifically,
TARO automates specimen sorting to the appropriate assay batch, enhances specimen tracking applications and reduces manual set up procedures at the analytical workbench.

As
part of our continuing emphasis on productivity improvements, we have developed an ancillary system to TARO that is designed for high-throughput, precise
aliquoting. This automated system, known as the Harmonized Assignment of Nanoliter Aliquots, or HANA, we believe is substantially reducing the traditional manual process of dividing
specimens into smaller components when multiple tests are requested on a single patient. Like TARO, this system is expected to deliver higher quality service levels to our customers while
at the same time improve our operating efficiencies. This system became operational in second half of 2002. Due to the precision of this automation, HANA had an immediate impact by
identifying patient samples as containing insufficient specimen volume for tests to be performed, and thus lowering the number of patient samples that had to be handled.

We
utilize information technology applications extensively in conjunction with automated specimen management systems at the analytical site within the laboratory. We will continue to
explore other projects to enhance our processes for improved accuracy and productivity.

Research and Development

The role of R&D at Specialty continues to be the driving force of new assay development, evaluating alternatives to costly diagnostics, improving existing assay
performance and commercializing existing technologies developed by our strategic partners. Our new, more focused approach on assay development will result in a smaller number of tests developed than
in the past, and a greater emphasis on revenue opportunities. Our process of creating a new assay begins with input from many sources, including our scientific team, our marketing department,
scientific symposia, customers, and scientific journals. A team composed of representatives from R&D, marketing and operations evaluates the potential for a proposed assay, examining issues from
disease prevalence to production costs. In
addition to clinical utility of the tests, we review other decision-making variables such as physician acceptance, relationship to an available therapeutic, reimbursement, and other variables
impacting the possible success of a test release. All of our R&D efforts have been company-sponsored. No R&D efforts have been sponsored by our customers. R&D spending has averaged $2.2 million
per year for the past three years. Our R&D efforts enable us to grow revenues, increase market share and command premium pricing for many of our assays.

To
advance our internal development efforts of new technology applications, we seek strategic partners whose technology can be applied to a variety of disease conditions and produce
advantages related to accuracy, performance, and speed of testing or cost reduction.

Strategic Partnerships and Licensing Arrangements

We actively pursue strategic partnerships with the developers of both new diagnostic assays and new platform and process technologies that accelerate assay
development and commercialization. Such relationships allow us to expand our range of offered services, reduce our costs and increase the accuracy of performing assays. In addition, some of these
agreements provide us with the potential to collect royalties from diagnostic product manufacturers for assays that we commercialize using such technologies.

10

---



During the past two years, we licensed intellectual property that has enabled us to commercialize several new assays. Among them are Phenoscript, an
HIV phenotyping assay that we licensed from VIRalliance, a subsidiary of Paris-based BioAlliance Pharma; TPMT, a genetic marker for reduced metabolism of thiopurine-based drugs that we licensed from
DNA Sciences; andCOL1-A1, a genetic marker for predisposition to osteoporosis that we licensed from Axis-Shield. We anticipate
that licensing new-assay intellectual property will be increasingly important in the future.



We have a large and growing number of diagnostic platform and process technology partners, including:



Proprietary Rights

We protect the proprietary methodologies for assays developed by our R&D group as our trade secrets. All of our employees and consultants sign a proprietary
information and inventions agreement upon hiring. To date, we have experienced no known material theft of trade secrets. We have copyrighted the proprietary software developed for products such as
DataPassport®, DataPassportMD®, Outreach Express® and TARO. We also have obtained copyright registrations, as appropriate, for our published books and
clinical information which we provide either electronically or in print to requesting clinicians. Many of our assays are branded products and we have applied for trademark registrations accordingly.
We also have registered marks used in our clinical information and other advertising materials.

In
April 2000 and June 2001, we received letters from the National Institutes of Health, the NIH, advising us that it believes that two of our assays, HIV-1
GenotypR and HIV GenotypR-PLUS, infringe its U.S. Patent 5,252,477. The patent is generally directed to the human HIV protease amino acid and DNA sequences and
methods for synthesis and purification.

We
received a letter from Chiron Corporation in or about February 1998 claiming that some of our Hepatitis C, or HCV, assays may be covered by its U.S. Patent 5,714,596. As of
June 23, 2000, we entered into an agreement to purchase the majority of our HCV assays from Bayer Corporation, which has represented that it has a license for U.S. Patent 5,714,596.

Neither
NIH nor Chiron has filed suit against us, though we cannot provide any assurances that they will not do so in the future. We intend to defend any such suit that may arise
vigorously and to assert all available defenses to allegations of patent infringement that would be available to us. Such

11

---

suits could be expensive to defend and could divert management's time and resources, regardless of the merit or validity of any such suit. Furthermore, we cannot provide any assurances that we would
be successful in defending any such suit, and if we were found to have infringed the patents at issue, including those of NIH and of Chiron, we could be forced to pay substantial damages, including
possible treble damages for allegations of willful infringement.

Competition

The esoteric clinical laboratory business is highly competitive and is dominated by several national laboratories, as well as many smaller niche and regional
organizations. Our primary competitors include large independent laboratories, such as Quest Diagnostics and Laboratory Corporation of America Holdings, or LabCorp, that offer a wide test and product
menu on a national scale. These large national independent laboratories have significantly greater financial, sales and logistical resources than we do and may be able to achieve greater economies of
scale, or establish contracts with payor groups on more favorable terms than we can. We also compete with smaller niche laboratories, like Impath and Athena Diagnostics, that address a narrow segment
of the esoteric market by offering very specific assay menus. Finally, institutions that are affiliated with large medical centers or universities, such as Mayo Medical Laboratories and Associated
Regional University Pathologists, generally lack the advantages of larger commercial laboratories, competing with us on the limited basis of a perceived higher quality of service.

We
believe that healthcare providers consider the following factors, among others, in selecting an esoteric clinical laboratory:



We
believe that we compete favorably with our principal competitors for esoteric testing services in these areas. However, we cannot assure you that we will maintain our competitive
position in the future.

Quality Improvement

We maintain a comprehensive quality improvement program that monitors and evaluates performance to ensure accuracy and precision in pre-analytical,
analytical, and post-analytical processes of clinical laboratory testing. The processes are documented with policies and procedures that are based upon nationally standardized guidelines
on test performance and results interpretation. This also includes the routine monitoring of control results, and blind specimen submissions to assess accuracy and reproducibility. We believe that we
have obtained all appropriate approvals and licenses for providing clinical laboratory testing services. We participate in numerous quality and proficiency testing programs, including the proficiency
programs administered by the College of American Pathologists and other state, national and international programs. In addition, the laboratory participates in the College of American Pathologists
Laboratory Accreditation Program, which requires inspection by outside experts and self-evaluation.

All
laboratory testing and associated processes are described in written policies, procedures and validations under electronic document control. These documents include instructions for
routine monitoring of quality control data, tolerance limits, and corrective actions taken if tolerance limits are exceeded.

Government Regulation



Numerous federal and state laws provide for penalties in connection with improper billing practices involving healthcare services. Remedies under these laws
include imprisonment, monetary penalties, multiples of damages, asset forfeitures, and exclusion from federal and state healthcare payment programs. These laws include, among others, the federal False
Claims Act, which prohibits the submission of fraudulent claims in connection with Medicare, Medicaid and certain other governmental programs. Monetary penalties of up to $11,000 for each improper
claim plus treble damages can be recovered under the False Claims Act. In addition to direct suits by the federal government, the False Claims Act authorizes private parties to bring suit on behalf of
the government against providers and entitles such a person to a portion of any final recovery. In addition, the Social Security Act provides for civil monetary penalties of up to $10,000 for each
service improperly billed for and recovery of treble damages for services which are fraudulently billed to the Medicare program or a Medicaid program. Providers convicted of any criminal offense
relating to their provision of Medicare or Medicaid covered services or of certain felonies in connection with other private or governmental healthcare programs are subject to mandatory exclusion from
the Medicare and Medicaid programs. In addition, the federal Centers for Medicare & Medicaid Services (CMS) (formerly known as the Health Care Financing Administration or HCFA) may exclude from
the Medicare and Medicaid programs any provider convicted under state or federal law of certain offenses relating to fraud or other misconduct in connection with the provision of health care services,
or who has been subjected to a civil monetary penalty under the above-described provisions of the Social Security Act. CMS also may suspend Medicare payments to any provider it believes has engaged in
fraudulent billing practices. Remedies generally similar to those described above are also available to state Medicaid programs, and California law also denies Medi-Cal enrollment to any
provider that has entered into a settlement in lieu of conviction for fraud or abuse in any government program and further provides that a provider that is under investigation by certain government
agencies for fraud or abuse shall be subject to temporary suspension from the Medi-Cal program.

The
federal government has investigated and continues to investigate the billing practices of numerous clinical laboratories. Such investigations and related litigation have involved a
broad range of issues, including the practices of laboratories of grouping tests into panels for billing and ordering purposes, the marketing of tests to physicians, billing for hematology tests and
indices, billing for tests not performed, double billing, billing for tests which are not medically necessary, improper coding, and numerous other potentially improper practices. These investigations
have resulted in all of the largest national independent laboratory companies, as well as many regional and local laboratories, having entered into settlement agreements in amounts that in several
instances have exceeded $100 million. While most fraud enforcement activity has involved the Medicare and Medicaid programs, lawsuits by private insurance companies based upon fraud theories
are also common. To our knowledge, we are not subject to any investigations or lawsuits alleging fraudulent billing practices. However, there can be no assurance that our activities will not be
challenged under the fraud laws in the future.

Independent
of fraud allegations, Medicare and Medicaid programs and private payors may retroactively determine that certain payments for services must be repaid due to a failure to
satisfy applicable payor requirements. Significant delays in or recoupments of payments could have a material adverse effect on our revenues.

"Self-Referral" Legislation.We are subject to "self-referral" prohibitions under federal Medicare
law, commonly known as the Stark Law and to similar restrictions of California law, such as the Physician Ownership and Referral Act, which apply to referrals by California physicians. We are also
subject to similar self-referral laws of several other states in which we conduct business. When taken together, these restrictions generally prohibit us from billing the patient or any
governmental or private payor for any test when the physician ordering the test, or any relative of such physician, has an investment interest in, or compensation arrangement with us.

Both
the Stark Law and the Physician Ownership and Referral Act contain an exception for referrals made by physicians who hold investment interests in a publicly traded company that has
shareholders' equity of $75 million at the end of its most recent fiscal year, and satisfies certain other requirements. California's self-referral restrictions applicable to
referrals of workers' compensation testing also contain a similar exception, except that this exemption requires that total gross assets at the end of the laboratory's most recent fiscal year has to
be at least $100 million. At our fiscal years ended December 31, 2002, 2001 and 2000, our shareholders' equity and total assets exceeded $100 million, and we are therefore now
entitled to the benefit of the public company exemptions. However, the public company exemptions most likely were not available to us prior to January 1, 2000. Because many of our shareholders
hold stock in the name of their stock brokerage firm, it may not have been possible for us to fully comply with the self-referral requirements prior to our qualifying for the public
company exemptions. Despite the public company exemptions, we will need to monitor our compensation relationships with physicians under the self-referral laws on an on-going
basis. For example, our provision of information technology support to physician customers must be carefully structured in order to comply with the self-referral laws. Laboratories which
violate the Stark Law must refund any amounts collected in connection with prohibited referrals and are also subject to monetary penalties of $15,000 for each test improperly billed for and exclusion
from the Medicare and Medicaid programs. In addition, billings for services where the referral was prohibited may be actionable under false claims statutes. Substantial penalties may also be imposed
in the event of Physician Ownership and Referral Act violations. Although we believe that we are in compliance in all material respects with the Physician Ownership and Referral Act and the Stark Law,
there can be no assurance that we will not be found to be in violation of these laws in the future. In addition, other states have self-referral restrictions with which we may have to
comply that may differ from those imposed by federal and California law.

Regulations
implementing and interpreting certain provisions of the Stark Law were released by CMS with an effective date of January 4, 2002. Provisions contained in the
regulations which define the types of indirect compensation relationships to which the Stark Law applies and which create new exceptions for certain types of financial relationships may have some
relevance to us. In addition, the regulations interpret an exception under the Stark Law which allows laboratories to provide physicians with supplies used solely to collect, transport, process or
store specimens. CMS believes this exception is limited to items of low value, such as single use needles, vials and specimen cups, and that biopsy needles, and similar items such as snares, reusable
aspiration and injection needles and sterile gloves, do not function solely as specimen collection devices, and therefore trigger the self-referral restrictions if they are provided
without a fair market value charge. However, California's self-referral restrictions contain no exemption which would allow such items to be sold to physicians, even at fair market value,
and a laboratory complying with CMS interpretations may be required to have its California physician customers obtain the restricted types of supplies from third parties. The Stark Law regulations
also acknowledge that a laboratory's provision of the services of a phlebotomist without charge is permitted so long as the phlebotomist performs solely laboratory functions for the laboratory
providing the phlebotomist. Because the prior regulations largely implemented the Stark Law as it applies to clinical laboratory services, we do not believe that the 2002 regulations will have any
material impact on us.

Anti-kickback Laws.The federal Medicare/Medicaid anti-kickback statute prohibits laboratories from
paying remuneration as inducement for referrals of patients or specimens for testing paid for by the Medicare or Medicaid programs. Certain practices that might otherwise violate the
anti-kickback statute are protected under certain "safe harbor" regulations which have been promulgated by Medicare's Office of Inspector General (OIG). Based upon a federal court decision
specifically considering physician ownership of laboratories and an anti-kickback safe harbor regulation applicable to investments in certain publicly traded companies, we believe that a
challenge to physician investments in our company is unlikely.

A
number of business practices in the clinical laboratory industry have been criticized by the OIG, including the provision of phlebotomy staff to clients who perform clerical or other
functions for the client which are not directly and solely related to the collection or processing of laboratory specimens, the provision of computers or fax machines to clients which are not used
exclusively in connection with performance of the laboratory's work, the lease of space in a physician's office for rent which exceeds the fair rental value of such space, certain acquisition
agreements where the sellers may make referrals to the buyer after the sale and other compensation relationships between laboratories and entities from which they receive referrals, or to which they
make referrals, if such relationships are intended to induce referrals. In addition, the OIG has indicated that discounts given by laboratories to clients with respect to their private pay patients
and/or HMO patients must not be intended to induce referrals of Medicare or Medicaid patients by the client to the laboratory. Our business practices are governed by the anti-kickback
laws, including our negotiated discounted pricing arrangements, our participation in group purchasing organizations and provision of information technology to our customers. We believe the Office of
Inspector General's concerns regarding discounts should not apply to us, in part because of statutory exceptions and safe harbor regulations are available to protect certain discounts offered to
customers. We also believe that certain payments we make to group purchasing organizations are protected under a safe harbor regulation.

Many
states, including California, also prohibit payments from being given to physicians, hospitals or others by clinical laboratories as compensation or inducement for referrals of
patients or test specimens, regardless of the source of payment for such testing. In addition, laboratories offering pricing to their customers that is more favorable than that offered directly to
patients may be deemed to pay prohibited kickbacks under state laws. However, we believe that a kickback will not result under California law if the laboratory's customer passes all of such discount
to its patients in the form of lower testing charges. Because we expect our California customers to comply with the "pass through" requirements applicable to them, we do not believe that any favorable
pricing we offer to California physicians or hospitals violates California's anti-kickback laws. However, it is possible that markups by our non-California customers who are
not bound by anti-markup restrictions may implicate anti-kickback laws.

Any
action taken against us under the Medicare/Medicaid anti-kickback statute could result in criminal penalties being imposed pursuant to the U.S. Sentencing Guidelines,
civil monetary penalties of $50,000 per violation plus treble damages, and exclusion from Medicare and Medicaid participation. Laboratories that violate the California anti-kickback laws
or similar anti-kickback, anti-markup, or direct billing laws of other states may be subject to loss of licensure and substantial fines.

While
we believe that we are in compliance in all material respects with the anti-kickback statutes, there can be no assurance that our relationships with physicians,
hospitals and other customers will not be subject to investigation or a successful challenge under such laws. If imposed for any reason, sanctions under the anti-kickback laws could have a
material adverse effect on our business.



We are required to maintain various federal and state licenses, certifications and permits. Our laboratory is certified pursuant to the Clinical Laboratory
Improvement Amendments of 1988 (CLIA),

15

---

which subject clinical laboratories to national standards. Because of the location of our laboratory in Santa Monica, licensure is also required under the laws of the State of California. Since we
perform patient testing from all states, we hold licenses in additional states where such licensure is required by local state law, including Florida, Maryland, New York, Pennsylvania, Ohio, West
Virginia, and Rhode Island. Our laboratory is also accredited with distinction by the College of American Pathologists, a private accrediting agency that has deemed status under CLIA.

The
federal and state agencies have established requirements and detailed specifications for the day-to-day operation of a clinical laboratory. These requirements
address: training, education, and competency of testing and supervisory personnel; design and implementation of a scientific quality
control program; documents that fully characterize method performance (validations) and execution (procedures); and a comprehensive quality improvement program. In addition, federal law mandates
performance in a graded and CLIA-approved proficiency testing program. This involves testing of unknown specimens that have been specifically prepared for the laboratory to evaluate
performance. A final rule revising the CLIA regulations was published on Januarys 24, 2003. This new regulation deals primarily with quality control procedures, and we do not expect that the new
regulations will have a significant impact upon us. If a laboratory is out of compliance with CLIA or other applicable requirements, CMS and/or the California Department of Health Services (CDHS) may
assess substantial civil money penalties, restrict tests that the laboratory may perform, impose specific corrective action plans, suspend the laboratory's approval to receive Medicare and Medicaid
payments, and/or suspend, revoke or limit the laboratory's CLIA certificate or state license. If a laboratory's CLIA certificate or state license is suspended or revoked, its ability to perform
further testing is terminated. In addition, certain types of non-compliance may make a laboratory's services ineligible for reimbursement under Medicare and/or Medicaid programs, even in
the absence of any formal enforcement action. Sanctions imposed by individual states may restrict testing for residents of that state.

In
June 1999, CMS informed us that we were not in compliance with CLIA regulations pertaining to specific quality assurance functions, and imposed certain fines in connection
therewith. After a CMS resurvey in June 2000, we were able to satisfy CMS that we were in compliance with the applicable requirements. We appealed the fine imposed by CMS, and subsequently
settled the matter by paying CMS the sum of $87,400.

In
June and October 2001, we underwent unannounced inspections by CDHS representing both the State of California and acting as agent of CMS under CLIA. As a result, we were cited
by CDHS with 20 deficiencies under California law and CLIA. A separate statement indicating 12 overlapping deficiencies under CLIA was issued by CMS in February 2002 based upon the same
inspections. We submitted a response and corrective action plan to CDHS in December 2001 in response to the CDHS statement of deficiencies. A more detailed response and corrective action plan
was submitted to CMS in February 2002 in response to the CMS statement of deficiencies. By letter dated February 28, 2002, CDHS determined that the December 2001 submission did
not constitute a credible allegation of compliance.

By
letter dated March 28, 2002, CDHS notified us of its intent to impose sanctions of a directed plan of correction, random onsite monitoring, and a civil money penalty based upon
deficiencies cited on November 28, 2001 following laboratory inspections conducted during June and October 2001. The sanctions were based on findings that we were permitting unlicensed
personnel to perform and supervise clinical laboratory testing in violation of California law.

By
letter dated April 12, 2002, CMS notified us of its conclusions regarding the laboratory inspections in June and October 2001. CMS concluded that our
February 2002 response to deficiencies detected in the inspections did not constitute a credible allegation of compliance. As a result, CMS imposed certain sanctions, including notice of
revocation of our CLIA certificate, cancellation of our approval to receive Medicare and Medicaid payments for services performed, imposing a civil money

16

---

penalty of $3,000 per day for each day during the sanction period, and imposing a directed plan of correction by which CMS could notify our customers of our non-compliance and the nature
and effective date of any sanctions imposed. We filed an appeal to the CMS action on April 17, 2002, and the appeal stayed the revocation of our CLIA certificate during our administrative
appeal. The cancellation of Medicare and Medicaid payments was effective for services performed by us on and after February 22, 2002.

We
filed supplemental documentation supporting our compliance with the applicable requirements with CDHS and CMS on April 26, 2002. In addition, on April 26, 2002, we
requested that CDHS rescind its proposed sanctions outlined in the March 28, 2002 letter based on our supplemental submission. In May and June 2002, CDHS conducted additional unannounced
inspections, and we provided additional documentation supporting our compliance with CDHS requirements. By letter dated June 28, 2002, and amended on July 18, 2002, CDHS indicated that
we were in substantial compliance with California clinical laboratory law. CDHS also imposed sanctions of a civil money penalty of $1,000 per day for 344 days (i.e., $344,000), plus $20,430 for
the cost of conducting their investigations, and imposed onsite monitoring for three years, including unannounced inspections. We did not appeal these imposed sanctions.

On
July 17, 2002, CMS notified us that it had deemed Specialty in compliance with all condition level requirements of CLIA as of June 19, 2002, that Specialty's right to
bill Medicare and Medicaid for its testing services was reinstated as of June 19, 2002, and that all actions against our CLIA certificate were rescinded. In order to facilitate an immediate
resolution with CMS, we elected to withdraw the appeal of the sanctions we filed with CMS on April 17, 2002, and we will not seek reimbursement for services performed for beneficiaries of
Medicare and Medicaid during the sanction period of February 22, 2002 through June 19, 2002. However, because CMS had imposed its sanctions retroactively to February 22, 2002, we
had billed Medicare and Medicaid programs for some services before we were notified of the actual imposition of the sanctions by CMS on April 12, 2002. We have sought guidance from CMS as to
how the period of retroactive sanctions should be treated, and we have set aside and reserved those Medicare or Medicaid payments from the period of February 22, 2002 through April 12,
2002 until we receive additional guidance from CMS. We also did not challenge CMS' imposition of a monetary fine of $351,000, representing $3,000 per day during the sanction period. We believe that
the cancellation of our approval to receive Medicare and Medicaid payments for services performed from February 22, 2002 through June 19, 2002 did not affect testing for Medicare and
Medicaid patients for whom we bill our hospital and other clients, but instead applies only to testing for which we bill the Medicare and Medicaid programs directly.

In
October 2002, the College of American Pathologists (CAP) completed a regularly scheduled inspection of our laboratory facilities. The CAP inspection found that we had met the
CAP requirements and standards for accreditation, and CAP issued us its Accreditation with Distinction as a result of the October 2002 inspection.



We have reviewed the pertinent regulations of CLIA and related rulings and policy guidelines and believe that our business practices adhere to the stated
requirements in all material respects. We will continue to monitor legislation and implement required guidelines or regulations. However, there can be no guarantee that we will pass all future
inspections or otherwise be found to be in full compliance with these and other regulations.

In
addition, the Department of Health and Human Services' (HHS) Office of the Inspector General has suggested that laboratories adopt a written compliance plan to promote standards of
ethics and business practice that will help to prevent fraudulent conduct. We have adopted such a compliance plan, and have a Compliance Officer to assist us with our compliance with these ethics and
business

practices, as well as applicable state and federal regulations relating to billing, structuring of relationships between ourselves and our partners and clients, and with other non-CLIA
requirements.



California law, as well as the laws of many other states, prohibit physicians from sharing professional fees with non-physicians such as laboratories,
and prohibit non-physicians from practicing medicine, including pathology, and from employing pathologists or other physicians. California law provides that the practice of medicine
without a license is a misdemeanor, and a violation of the laws governing the practice of medicine could be a basis for assessment of fines and penalties, imposition of a cease and desist order, and
the suspension or revocation of a California laboratory license. State and federal law also prohibit us from being compensated for referrals we make to our pathologists. We have previously employed
pathologists, and are restructuring our relationships with pathologists in a manner that we believe does not violate the prohibitions against the "corporate practice" of medicine in any material
respect. We do not believe that any violations which we may have committed in the past are likely to result in sanctions that would have a material adverse effect on our business, financial condition,
results of operations, or cash flows.



The federal Food and Drug Administration (FDA) regulates the manufacture of medical devices, including laboratory testing equipment, diagnostic kits and certain
reagents. While the FDA believes that it has authority to regulate tests developed by laboratories for their own use, the FDA, to date, has allowed the development of such tests to proceed under the
regulations under CLIA governing a
laboratory's development of its own assays. The FDA is testing methods for laboratories to register their in-house assays. The FDA has also subjected the commercialization of certain
immunohistochemical stains, tumor markers and analyte specific reagents to limited regulation, and requires us to make certain disclosures in connection with their use. In addition, the FDA has
announced that it is evaluating whether it should regulate analyte specific reagents as either Class II or Class III medical devices. The federal Centers for Disease Control and
Prevention (CDC) is revising the regulations under CLIA to specifically recognize and regulate a genetic testing specialty. In addition, the Department of Health and Human Services' (HHS) Secretary's
Advisory Committee on Genetic Testing (SACGT) until recently advised HHS as to various issues raised by the development and use of genetic testing. SACGT published recommendations that included FDA
review of individual tests, and augmentation of revised CLIA standards to be written by the CDC. In January 2003, HHS indicated it is still assessing the feasibility of regulating
in-house genetic testing, and HHS recently created a new committee, the Secretary's Advisory Committee on Genetics, Health and Society, to take over and expand on the role of SACGT. Our
existing and future assays may be subject to federal regulatory approval similar to the pre-marketing approval process that the FDA applies to drugs and medical devices, or may be subject
to other increased regulatory standards, which could have a negative effect on our business. If the FDA seeks to regulate in-house genetic testing, depending the nature and scope of such
regulation, it could have detrimental effect on our business. At the state level, the New York State Department of Health now requires detailed review of our scientific validations and technical
procedures for each assay before approval for NY residents; the level of scrutiny delays test availability.



Pursuant to the Occupational Safety and Health Act (OSHA), laboratories must provide a safe workplace to their employees. In response to this requirement, OSHA
has issued rules and regulations to protect workers from blood-borne pathogens and other hazards that are commonly found in laboratories. We are also subject to licensing and regulation under federal,
state and local laws relating to the handling and disposal of medical specimens, hazardous waste and radioactive materials. We are

18

---

also subject to regulations of the Department of Transportation, the Public Health Service's Centers for Disease Control & Prevention and the Postal Service which apply to the surface and air
transportation of laboratory specimens. Although we believe that we are currently in compliance in all material respects with the above laws, failure to comply could subject us to denial of the right
to conduct business, fines, criminal penalties and other enforcement actions.

Changes in Laboratory Reimbursement



A number of proposals aimed at reducing healthcare costs or increasing healthcare insurance coverage have been considered in recent years which, if enacted, would
have affected major reforms of the healthcare system. Such proposals include: decreases in reimbursement amounts, increased enrollment of Medicare beneficiaries in managed care systems, increased
availability of health insurance to individuals and to small businesses, requirements that all businesses offer health insurance coverage to their employees, the provision of tax credits for purchase
of health insurance, the formation of regional "health alliances" to act as healthcare purchasing agents and the creation of a government health insurance plan that would cover all citizens. We cannot
predict whether any of these or other proposals will be adopted at the state or federal levels, or what effect, if any, such proposals would have on our business.



For testing performed other than for hospitals, nursing facilities and other laboratories, laboratories are required to bill Medicare and Medicaid directly, and
generally must accept reimbursement from these programs as payment in full for services performed for Medicare and Medicaid patients. Such direct billings by us to Medicare accounted for approximately
3.4% of our net revenue in 2001 and approximately 2.9% of our net revenue for 2002. Medicaid net revenue was approximately 1.4% of our net revenue in 2001 and 1.9% of our net revenue in 2002. However,
a substantial portion of the testing for which we bill our hospital and independent laboratory customers is for Medicare and Medicaid patients, and we do not know the percentages of our net revenue
that are indirectly derived from these programs. Any pricing pressure exerted by these programs on our customers may cause them to reduce their payments to us.

Congress
has established maximum fee schedules for clinical laboratory testing performed for Medicare beneficiaries, excluding hospital and nursing facility patients. Payment by Medicare
for laboratory services performed for hospital inpatients and outpatients and for nursing facility inpatients is included in the prospective payment rates paid to the patient's facility. State
Medicaid programs are prohibited from paying more for testing than the Medicare fee schedule amounts and, in most instances, they pay significantly less. When initially established, the Medicare fee
schedules were set at 60% of prevailing local charges. Maximum reimbursement rates for clinical laboratory testing have subsequently been substantially reduced, and it should be expected that such fee
schedules will be further reduced in the future. For example, a ceiling on Medicare and Medicaid payments to laboratories commonly referred to as the "national cap" amount has been reduced numerous
times in recent years, and most recently was set by Congress at 74% of the national median of local fee schedules. However, while Congress had eliminated consumer price index increases to the national
cap and local fee schedules through the year 2002, a 1.1% inflation increase to the fee schedules (and therefore also to the national cap) was made for 2003. Medicare reimbursement has also been
reduced from time to time by an effective rate of between 1% and 2% pursuant to Gramm-Rudman-Hollings sequestration. In addition, from time to time, proposals have been made that beneficiary cost
sharing again be applied to laboratory testing paid for by Medicare. If such a proposal were adopted, the costs of billing and collecting co-payment amounts and associated bad debt could
reduce the revenue actually realized by laboratories.

19

In
December 2002, the Centers for Medicare & Medicaid Services ("CMS") issued a new Interim Final Rule which sets forth the process for establishing a "realistic and
equitable" payment amount for all Medicare Part B services (except physician services and services paid under a prospective payment system) when the existing payment amounts are determined to
be inherently unreasonable because they are either "grossly excessive or deficient." We cannot predict what effect, if any, this rule and its implementation will have on our business.

Current
economic conditions have caused many states to face substantial budget shortfalls. As a result, many states are considering reducing payments made to providers of health care
services by their Medicaid programs. As an example, California's governor has announced his intention to propose a budget that would generally reduce Medi-Cal reimbursements by 15%. CDHS
has announced that laboratories will not be exempted from any cuts that may be made. Based upon the limited information available, it appears that such cuts may become effective as early as
July 1, 2003. As a result, substantial reductions may be made in the future to our Medi-Cal reimbursements, and it is possible that we will face substantial reductions in the
reimbursement which we receive under other states' Medicaid programs as well.

Medicare Reimbursement for Technical Component of Hospital Pathology Services.In the past, independent laboratories have
been permitted to bill for the technical component of certain pathology services which are performed for Medicare hospital patients. CMS promulgated regulations to end such separate billing as of
January 1, 2001. Congress has enacted legislation delaying implementation of the CMS rules until January 1, 2003 for hospitals who had qualifying outsourcing contracts for pathology
services in place as of July 22, 1999. While legislation was introduced in Congress in 2002 to further delay implementation of the new requirements, no such legislation was enacted. It is
expected that Congress will take this issue up again in 2003. On January 17, 2003, CMS issued a program memorandum instructing carriers to continue payment for these services indefinitely. It
is not clear if or when the new requirement will come into effect, or what time period it will cover. Any such services we perform for hospitals without qualifying arrangements or after the new
requirements become effective will have to be billed to the patient's hospital. Hospitals will receive no additional reimbursement from Medicare for these pathology services provided to inpatients,
and reimbursement for these services under the new outpatient prospective payment system may be lower than it was previously. Such changes therefore may result in a reduction in the payments we
receive from hospitals for these services.

Elimination of Dual Charge Structure.Proposals have been made to restrict "dual charge" billing practices under which
laboratories charge higher fees to Medicare and Medicaid than are charged to physicians, hospitals, laboratories and other purchasers who are in a position to negotiate favorable rates. Thus, it has
been proposed that existing authority for HHS to exclude from Medicare and Medicaid program participation any providers that charge amounts to the Medicare program that are "substantially in excess"
of their "usual charges" be used to respond to laboratory pricing practices. Similarly, CMS is permitted to adjust statutorily prescribed fees for some medical services, including
clinical laboratory services, if the fees are grossly excessive and therefore not inherently reasonable. CMS has issued an interim final rule setting forth criteria to be used in determining whether
the otherwise statutorily prescribed fees should be reduced which includes consideration of whether such fees are grossly higher or lower than the payment made for the services by other purchasers in
the same locality. Fees payable by Medicare for clinical laboratory services may be reduced as a result of the application of the above rules or by similar restrictions which may be applied in the
future.

In
addition, the California Medi-Cal program is required by California regulations to pay no more for testing than the amount which a laboratory charges pursuant to any fee
schedule it applies generally to its physician or hospital customers. While the extent to which this rule applies to our discounts which are negotiated on a case-by-case basis
is unclear, it is possible that a recoupment action could be bought against us based upon discounts which we give to certain customers.

20

---

Contracts for Laboratory Services.Proposals have been made to require competitive bidding procurement of Medicare laboratory
testing services. CMS is required to complete five Medicare bidding demonstrations involving various types of medical services and CMS is expected to include a clinical laboratory demonstration
project in a metropolitan statistical area. Similarly, California legislation enacted several years ago required the implementation of a program of negotiated laboratory service contracting for the
Medi-Cal program. The Medi-Cal program has announced its intent to move forward with implementing its contracting program, but has not yet announced details as to how the
contracting program will work. While it is expected that contracts will be entered into with many laboratories, there can be no assurance that we will be allowed to participate under the new program
or that we will be able to enter into contracts on favorable terms. In addition, a large portion of the Medi-Cal program has been converted into a managed care system, resulting in
negotiated laboratory service contracts between laboratories and other providers of healthcare services. Increased enrollment of Medicare or Medicaid beneficiaries in HMOs or negotiated contracting
arrangements may also result in a larger portion of our business being subject to negotiated contracts with payors.

To
obtain competitively bid contracts to perform services, it might be necessary for us to agree to substantial reductions in our payments from the Medicare and Medi-Cal
programs. Such contracts may be exclusive and laboratories which do not hold such contracts may be denied access to the Medicare/Medi-Cal testing market and could have difficulty obtaining
private patient testing from physicians participating in the contracting or managed care program.

Nongovernmental Efforts.Managed care arrangements may become increasingly prevalent in the clinical laboratory services
market. For example, HMOs, insurance companies and self-insured employers may provide laboratory services directly or contract with laboratories at favorable
fee-for-service or capitated rates and require their enrollees to obtain service only from such contracted laboratories. To the extent that we or our customers are unable to
obtain contracts to provide such testing services or must discount prices to obtain such contracts, our revenues and profit margins could be adversely affected.



Certain tests are only reimbursable by Medicare when the laboratory submits an appropriate diagnosis code which it has obtained from the ordering physician.
California's Medicaid program, known as Medi-Cal, has also adopted, a policy requiring that a diagnosis code be submitted in connection with all bills for laboratory tests which are
submitted to the Medi-Cal program where Medicare would require a diagnosis code if it were being billed for the tests. To the extent that the requirements for such diagnosis codes are
expanded to additional tests or are adopted by additional Medicaid programs or by private insurance programs, or we are unable to obtain required codes from physicians, our reimbursement could be
adversely affected.



The confidentiality of patient medical information is subject to substantial regulation by state and the federal governments. Specific state and federal laws and
regulations govern both the disclosure and use of confidential patient medical information, as well as access of patients to their own medical records. Similarly, many other federal laws also may
protect such information, including the Electronic Communications Privacy Act of 1986 and federal laws relating to confidentiality of genetic testing results, mental health records and substance abuse
treatment records.

Congress
passed the Health Insurance Portability and Accountability Act, known as HIPAA, in 1996. Among other things, HIPAA calls for the establishment of national standards to
facilitate the electronic exchange of health information and to maintain the security of both the health information and the system that enables the exchange of this information. HHS has promulgated
numerous regulations pursuant to its authority under HIPAA, including regulations that pertain to the security of

21

---

individually identifiable health information that is electronically maintained or transmitted and the privacy of individually identifiable health information that is transmitted, received and
maintained in any form or medium. Pursuant to these regulations, all medical records and other patient identifiable health information must be maintained in confidence, must not be used for
non-health purposes and must be disclosed to the minimum extent required. In addition, patients must be given a clear notice of their rights and access to their records by laboratories
(other than to the extent that access to their records is restricted by CLIA and by state law) and, unless permitted by applicable laws or regulations, a patient's authorization generally must be
obtained before information is released. To ensure that these requirements are satisfied, covered entities must adopt appropriate policies and practices, designate a privacy officer, train employees
and establish a grievance procedure. The privacy regulations recognize, however, that laboratories have little direct contact with patients, and therefore they allow healthcare providers with an
indirect treatment relationship with the patient to use protected health information for purposes of treatment and health care operations without a separate consent. Nonetheless, laboratories will
still have to directly address HIPAA regulations in other circumstances.

In
most circumstances, entities covered by HIPAA must be in compliance with the HIPAA regulations by the following compliance dates: (1) privacy regulations by April 14,
2003; (2) electronic transactions regulations by October 16, 2003 (if, like us, the organization covered by HIPAA filed for an extension); and (3) security regulations by
April 21, 2005. If we are found to have violated any state or federal statute or regulation with regard to the confidentiality, dissemination or use of patient medical information, we could be
liable for damages, or for civil or criminal fines or penalties. Because laboratory orders and reports fall within the scope of HIPAA, the costs of HIPAA compliance will impact us and others in the
clinical laboratory industry. Compliance with the HIPAA rules could require us to spend substantial sums, which could negatively impact our profitability. At this time, we cannot assess the total
financial or other impact of the HIPAA regulations upon us. While we believe we will be in compliance in all material respects with the HIPAA regulations when such regulations become effective, our
failure to comply could subject us to fines and penalties, and have a detrimental effect on our business.

Recent Developments

On
February 26, 2003, the previously reported acquisition of Unilab Corporation by Quest Diagnostics, Inc. was completed. Unilab previously was one of our largest
customers, and now that the acquisition of Unilab is complete, we believe that Quest will ultimately perform the majority of testing previously sent to us by Unilab. We have already seen a reduction
in test volumes sent to us by Unilab, and we expect further reductions as a result of the completion of Unilab's acquisition by Quest. On March 3, 2003 Unilab provided us notice that it would
stop sending us certain tests covered under a new agreement we reached with them in October 2002.

Employees

As of December 31, 2002, we employed 704 individuals. Twenty-one are engaged in research and development, 169 in administration and clerical
functions, 71 in sales and marketing, 37 in information technology and 406 in our clinical laboratory and related operations. None of our employees are represented by labor unions, and we believe our
employee relations are good.

RISK FACTORS

This Annual Report contains forward-looking statements based on the current expectations, assumptions, estimates and projections about
Specialty Laboratories, Inc. and the esoteric clinical laboratory industry. These forward-looking statements involve risks and uncertainties. Our actual results could differ materially from
those discussed in these forward-looking statements as a result of certain factors, as more fully described in this section and elsewhere in this Annual Report. If any of these risks actually occur,
our business, financial condition, results of operations and future growth prospects could be materially adversely affected. Additional risks and uncertainties not presently known to us or that we
currently believe to be immaterial also may impair our business. Any adverse effect on our business, financial condition or results of operations could result in a decline in the trading price of our
common stock and the loss of all or part of your investment. Specialty Laboratories, Inc. does not undertake to update publicly any forward-looking statements for any reason, even if new
information becomes available or other events occur in the future.

Our operations and facilities are subject to stringent laws and regulations and if we are unable to comply, our business may be significantly harmed.

As a provider of healthcare-related services, we are subject to extensive and frequently changing federal, state and local laws and regulations governing
licensure, billing, financial relationships, referrals, conduct of operations, purchases of existing businesses, cost-containment, direct employment of licensed professionals by business
corporations and other aspects of our business relationships.

If
we do not comply with existing or additional laws or regulations, or if we incur penalties, it could increase our expenses, prevent us from increasing net revenue, or hinder our
ability to conduct our business. In addition, changes in existing laws or regulations, or new laws or regulations, may delay or prevent us from marketing our products or cause us to reduce our
pricing.

Fraud and Abuse

Of particular importance to our operations are federal and state laws prohibiting fraudulent billing and providing for the recoupment of
non-fraudulent overpayments, as a large number of laboratories have been forced by the federal and state governments, as well as by private payors, to enter into substantial
settlements under these laws. Government investigations of clinical laboratories have been ongoing for a number of years and are expected to continue in the future. Written "corporate compliance"
programs to actively monitor compliance with fraud laws and other regulatory requirements are recommended by the Department of Health and Human Services' Office of the Inspector General and we have a
program following the guidelines in place.

Federal and State Clinical Laboratory Licensing

The operations of our clinical laboratory are subject to a stringent level of regulation under the Clinical Laboratory Improvement Amendments of 1988 (CLIA). For
certification under CLIA, laboratories such as ours must meet various requirements, including requirements relating to quality assurance, quality control and personnel standards. Since we perform
patient testing from all states, our laboratory is also subject to strict regulation by California, New York and various other states. We are accredited by the College of American Pathologists, a
private accrediting agency, and therefore are subject to their requirements and evaluation. Our failure to comply with CLIA, state or other applicable requirements could result in various penalties,
including restrictions on tests which the laboratory may perform, substantial civil monetary penalties, imposition of specific corrective action plans, suspension of Medicare payments and/or loss of
licensure, certification or accreditation. Such penalties could result in our being unable to continue performing laboratory testing. Compliance with such standards is verified by periodic inspections
and requires participation in proficiency testing programs.

23

In
June and October, 2001, we underwent unannounced inspections by the California Department of Health Services, or CDHS, representing both the State of California and acting as agent of
the federal Centers for Medicare & Medicaid Services, or CMS, under CLIA. As a result, the laboratory was cited by CDHS with 20 deficiencies under California law and CLIA. A separate statement
indicating 12 overlapping deficiencies under CLIA was issued by CMS in February 2002 based upon the same inspections. We submitted a response and corrective action plan to CDHS in
December 2001 in response to the CDHS statement of deficiencies. A more detailed response and corrective action plan was submitted to CMS in February 2002 in response to the CMS
statement of deficiencies. By letter dated February 28, 2002, CDHS determined that the December 2001 submission did not constitute a credible allegation of compliance.

By
letter dated March 28, 2002, CDHS notified us of its intent to impose sanctions of a directed plan of correction, random onsite monitoring, and a civil money penalty based upon
deficiencies cited on November 28, 2001 following laboratory inspections conducted during June and October 2001. The sanctions were based on findings that we were permitting unlicensed
personnel to perform and supervise clinical laboratory testing in violation of California law.

By
letter dated April 12, 2002, CMS notified us of its conclusions regarding laboratory inspections in June and October 2001 conducted by CDHS. CMS concluded that our
February 2002 response to
deficiencies detected in the inspections did not constitute a credible allegation of compliance. As a result, CMS imposed certain sanctions, including notice of revocation of our CLIA certificate,
cancellation of our approval to receive Medicare and Medicaid payments for services performed, imposing a civil money penalty of $3,000 per day for each day during the sanction period, and imposing a
directed plan of correction by which CMS could notify our customers of our non-compliance and the nature and effective date of any sanctions imposed. We filed an appeal to the CMS action
on April 17, 2002, and the appeal stayed the revocation of our CLIA certificate during our administrative appeal. The cancellation of Medicare and Medicaid payments was effective for services
performed by us on and after February 22, 2002.

We
filed supplemental documentation supporting our compliance with the applicable requirements with CDHS and CMS on April 26, 2002. In addition, on April 26, 2002, we
requested that CDHS rescind its proposed sanctions outlined in the March 28, 2002 letter based on our supplemental submission. In May and June 2002, CDHS conducted additional unannounced
inspections, and we provided additional documentation supporting our compliance with CDHS requirements. By letter dated June 28, 2002, and amended on July 18, 2002, CDHS indicated that
we were in substantial compliance with California clinical laboratory law. CDHS also imposed sanctions of a civil money penalty of $1,000 per day for 344 days (i.e., $344,000), plus $20,430 for
the cost of conducting their investigations, and imposed onsite monitoring for three years, including unannounced inspections. We did not appeal these imposed sanctions.

On
July 17, 2002, CMS notified us that it had deemed Specialty in compliance with all condition level requirements of CLIA as of June 19, 2002, that Specialty's right to
bill Medicare and Medicaid for its testing services was reinstated as of June 19, 2002, and that all actions against our CLIA certificate were rescinded. In order to facilitate an immediate
resolution with CMS, we elected to withdraw the appeal of the sanctions we filed with CMS on April 17, 2002, and we will not seek reimbursement for services performed for beneficiaries of
Medicare and Medicaid during the sanction period of February 22, 2002 through June 19, 2002. However, because CMS had imposed its sanctions retroactively to February 22, 2002, we
had billed Medicare and Medicaid programs for some services before we were notified of the actual imposition of the sanctions by CMS on April 12, 2002. We have sought guidance from CMS as to
how the period of retroactive sanctions should be treated, and we have set aside and reserved those Medicare or Medicaid payments from the period of February 22, 2002 through April 12,
2002 until we receive additional guidance from CMS. We also did not challenge CMS' imposition of a monetary fine of $351,000, representing $3,000 per day during the sanction

24

---

period. We believe that the cancellation of our approval to receive Medicare and Medicaid payments for services performed from February 22, 2002 through June 19, 2002 did not affect
testing for Medicare and Medicaid patients for whom we bill our hospital and other clients, but instead applies only to testing for which we bill the Medicare and Medicaid programs directly.

We
will be subject to additional future inspections. No assurances can be given that our facilities will pass all future inspections conducted to ensure compliance with federal or any
other applicable licensure or certification laws. Any inability to comply with federal, state or other applicable regulations could result in substantial monetary penalties, suspension of Medicare
payments and/or loss of licensure, certification or accreditation, and could divert a substantial amount of management's time
and resources. In addition, substantial expenditures are required on an ongoing basis to ensure that we comply with existing regulations and to bring us into compliance with newly instituted
regulations.

Food & Drug Administration

Neither the FDA nor any other governmental agency currently fully regulates the new assays we internally develop. Although the FDA previously asserted that its
jurisdiction extends to tests generated in a clinical laboratory, it has allowed these tests to be run and the results commercialized without FDA premarket approval. In January 2003, the U.S.
Department of Health and Human Services (HHS) indicated it is still assessing the feasibility of regulating in-house genetic testing, and HHS recently created a new committee, the
Secretary's Advisory Committee on Genetics, Health and Society, to take over and expand on the role of the former Secretary's Advisory Committee on Genetic Testing (SACGT). Our existing and future
assays may be subject to federal regulatory approval similar to the pre-marketing approval process that the FDA applies to drugs and medical devices, or may be subject to other increased
regulatory standards, which could have a negative effect on our business. If the FDA seeks to regulate in-house genetic testing, depending the nature and scope of such regulation, it could
have detrimental effect on our business. We cannot predict the extent of future FDA regulation and there can be no assurance that the FDA will not consider testing conducted at a clinical laboratory
to require premarketing clearance. Hence, we might be subject in the future to greater regulation, or different regulations, that could have a material effect on our finances and operations.

Anti-Kickback Regulations

Existing federal laws governing Medicare and Medicaid and other similar state laws impose a variety of broadly described restrictions on financial relationships
among healthcare providers, including clinical laboratories. These laws include federal anti-kickback laws which prohibit clinical laboratories from, among other things, making payments or
furnishing other benefits intended to induce the referral of patients for tests billed to Medicare, Medicaid or certain other federally funded programs. In addition, they also include
self-referral prohibitions which prevent us from accepting referrals from physicians who have non-exempt ownership or compensation relationships with us as well as
anti-markup and direct billing rules that may apply to our relationships with our customers. Sanctions for violations of these laws may include exclusion from participation in Medicare,
Medicaid and other federal healthcare programs, and criminal and civil fines and penalties.

Fee-Splitting

The laws of many states prohibit physicians from sharing professional fees with non-physicians and prohibit non-physician entities, such
as us, from practicing medicine and from employing physicians to practice medicine. If we do not comply with existing or additional regulations, or if we incur penalties, it could increase our
expenses, prevent us from increasing net revenue, or hinder our ability to conduct our business. In addition, changes in existing regulations or new regulations may delay or prevent us from marketing
our products or cause us to reduce our pricing.

25

---

Our accessions have declined and may continue to decline.

Because of uncertainty surrounding the sanctions imposed by CMS, questions about our clients' ability to bill for services we performed for them, and a reduction
in the number of assays we offer, some of our clients suspended or stopped sending us specimens for testing. As a result, our total accessions declined to less than 614,000 for the fourth quarter of
2002, and may continue to decline for the first quarter of 2003. While we expect accession volumes will stop declining, and will begin to grow again, due to factors including the potential of
continued uncertainty of our clients' responses to the regulatory issues we faced in 2002, and the loss of much of our Unilab business, we cannot provide any assurances that our clients will resume
sending us specimens for testing, nor can we provide assurances that our accessions will stop declining or begin to increase again.

A significant portion of our net revenue depends on a single customer, Unilab Corporation. If Unilab reduces or stops sending us specimens for testing, our business may suffer.

For the years ended December 31, 2002 and 2001, services to Unilab Corporation accounts comprised approximately 10.0% and 8.0% of our net revenue,
respectively. We previously entered into an agreement with Unilab in which it agreed to refer to us, until the agreement expired in October 2002, at least 90% of the esoteric laboratory
services it outsources each year or, in the event of a change of control of Unilab or the purchase by Unilab of a licensed clinical laboratory with a test menu materially broader than that of Unilab,
at least $800,000 of esoteric laboratory services per month.

On
April 2, 2002, Quest Diagnostics Inc. announced that they had entered into an agreement to acquire Unilab, and in February 2003 Quest completed its acquisition of
Unilab. As a result, we believe that Quest will ultimately perform the majority of testing previously sent to us by Unilab. Due to the pending acquisition, Unilab did not renew our agreement, which
expired in October 2002, and we experienced a significant reduction in testing volumes sent to us from Unilab in November and December of 2002. In October 2002, we entered into a new
agreement with Unilab which should provide for a more orderly reduction of the remaining testing volumes. However, the new agreement does not obligate Unilab to provide us with minimum assay
referrals, and is cancelable by either party upon thirty days prior notice. We have already seen a reduction in test volumes sent to us by Unilab, and we expect further reductions as a result of the
completion of Unilab's acquisition by Quest. If the new agreement with Unilab is terminated, or if Unilab starts performing certain testing at its own facilities, they may further reduce or stop
sending specimens to us for testing. In March 2003, Unilab provided us notice that it would stop sending us certain tests covered under the new agreement. We expect Unilab's purchase of our
services to be materially reduced during 2003. However, we cannot predict what the timing or extent of volume loss from Unilab will be, and such reductions or loss of testing volume may significantly
impact other future quarters. Any reduction in the purchase of our service by Unilab will decrease our net revenue.

Some of our customers are also our primary competitors. If they reduce or discontinue purchasing our assays for competitive reasons, it will reduce our net revenue.

Some of our customers, such as Quest, LabCorp, Mayo and ARUP, also compete with us by providing esoteric testing services. They often refer assays to us that they
either cannot or elect not to perform themselves. During 2002, we have seen a significant decline in test volumes referred to us from our competitors. For the year ended December 31, 2002,
sales to our competitors were less than 4% of our net revenue as compared to more than 6% of our net revenue for the year ended December 31, 2001. These parties may decide not to refer assays
to us because they wish to develop and market assays similar to ours, and we may experience a further decline in our net revenues from these competitors. For example, in July 1997, SmithKline
Beecham Clinical Laboratories, or SmithKline Labs, began to significantly limit the number of assays it referred to us. We believe that SmithKline Labs

26

---

terminated its relationship with us because it decided to offer assays similar to ours. In 1996, SmithKline Labs comprised 21.7% of our net revenue, whereas in 2001, after being acquired by Quest,
SmithKline Labs (excluding Quest accounts prior to the acquisition) only comprised approximately 2% of our net revenue. We experienced a significant reduction in volume from Quest, LabCorp, Mayo and
ARUP in 2002, and if these or other laboratories decide to reduce or discontinue purchases of our assays for competitive reasons, it will reduce our net revenue.

The esoteric clinical laboratory industry is intensely competitive. If we are unable to successfully compete, we may lose market share.

The esoteric clinical laboratory industry is highly competitive. This industry is dominated by several national independent laboratories, but includes many
smaller niche and regional independent laboratories as well. Our primary competitors include:



Large
commercial enterprises, including Quest and LabCorp, have substantially greater financial resources and may have larger research and development programs and more sales and
marketing channels than we do, enabling them to potentially develop and market competing assays. These enterprises may also be able to achieve greater economies of scale or establish contracts with
payor groups on more favorable terms. Smaller niche laboratories compete with us based on their reputation for offering a narrow test menu. Academic and regional institutions generally lack the
advantages of the larger commercial laboratories but still compete with us on a limited basis.

Any
of our competitors may successfully develop and market assays that are either superior to, or are introduced prior to, our assays. If we do not compete effectively with other
independent clinical laboratories, we may be unable to maintain or grow our market share.

Intense competition and consolidation in our industry could materially adversely affect our business, financial condition, results of operations and prospects.

The clinical laboratory industry is intensely competitive and highly fragmented. Our current competitors include large national laboratories that offer a wide
test and product menu on a national scale as well as smaller niche and regional organizations. Some of our large competitors have expanded, and may continue to expand, their competitive product
offerings through acquisitions. For example, Quest, the nation's leading provider of diagnostic testing and related services for the healthcare industry, recently acquired American Medical
Laboratories Incorporated, a national provider of esoteric testing to hospitals and specialty physicians, Clinical Diagnostics Services, Inc., a provider of routine and esoteric testing, and
Unilab Corporation, a leading clinical testing laboratory. LabCorp recently acquired Dianon Systems Inc., a leading U.S. provider of anatomic pathology and oncology testing services.
Acquisitions among existing and future competitors may allow them to rapidly gain greater market share. In addition, some of our customers refer assays to us that they cannot perform themselves. These
customers may no longer need to refer assays to us if they develop assays similar to us through the acquisition of other esoteric laboratories. A loss of market share and customers from such
acquisitions could materially adversely affect our business, financial condition, results of operations and prospects.

Our quarterly operating results may fluctuate and this could cause our stock price to fluctuate or decline.

Our quarterly operating results have varied significantly in the past and may vary significantly in the future. If our quarterly net revenue and operating results
fall below the expectations of securities analysts and investors, the market price of our common stock could fall substantially. Operating results vary depending on a number of factors, many of which
are outside our control, including:



Due
to these and other factors, results of operations and quarterly revenues are difficult to forecast, and we believe that period-to-period comparisons of our
operating results are neither meaningful nor predictive of future performance. In one or more future quarters our results of operations may fall below the expectations of securities analysis and
investors. In that event, the trading price of our common stock would likely decline.

In
addition, the trading price of our common stock may materially decline regardless of our operating results and performance. The market price of our common stock has been subject to
significant fluctuations since our initial public offering in December 2000. The stock market has experienced significant price and volume fluctuations that have affected the market prices of
securities, particularly securities of clinical laboratory, biotechnology and other health care service companies. In the past, following periods of volatility in the market price of a particular
company's securities, securities class action litigation has often been brought against that company. As previously announced such securities claims were filed against us in May and June 2002.
Litigation of this type is often expensive and diverts management's attention and resources, and we can provide no assurance, that we will be successful in
defending these actions. For more detailed description of the purported class-action securities claims recently filed against us, please see "Legal Proceedings."

We
plan to expand our sales and marketing, research and development and general and administrative efforts, which will lead to an increase in expenses. If our net revenue does not
increase along with these expenses, our business, financial condition, results of operations, or cash flows could be materially harmed and operating results in a given quarter could be worse than
expected.

For
a more detailed description of our operating results, please see "Management's Discussion and Analysis of Financial Condition and Results of Operations."

Our net revenue will be diminished if payors do not authorize reimbursement for our services.

There has been and will continue to be significant efforts by both federal and state agencies to reduce costs in government healthcare programs and otherwise
implement government control of healthcare costs. In addition, increasing emphasis on managed care in the U.S. may continue to put pressure on the pricing of healthcare services. Uncertainty exists as
to the reimbursement status of new

28

---

assays. Third party payors, including state payors and Medicare, are challenging the prices charged for medical products and services. Government and other third party payors increasingly are
limiting both coverage and the level of reimbursement for our services. Third party insurance coverage may not be available to patients for any of our existing assays or assays we discover and
develop. Third party payors accounted for approximately 7.3% of our net revenue in 2000, approximately 6.9% of our net revenue in 2001, and approximately 6.6% of our net revenue in 2002. However, a
substantial portion of the testing for which we bill our hospital and laboratory clients is ultimately paid by third party payors and we do not know the percentage of our net revenue that is
indirectly derived from these payors. Any pricing pressure exerted by these third party payors on our customers may, in turn, be exerted by our customers on us. If government and other third party
payors do not provide adequate coverage and reimbursement for our assays, our net revenue may decline.

In
April 2002, we received a letter from CMS imposing certain sanctions as a result of laboratory inspections conducted by CDHS in June and October 2001. The penalties
included cancellation of Medicare and Medicaid payments for services performed by us on and after February 22, 2002. On April 17, 2002, we filed an appeal to the sanction imposed by CMS.
On July 17, 2002, CMS notified us that it had deemed Specialty in compliance with all condition level requirements of CLIA as of June 19, 2002, that Specialty's ability to bill Medicare
and Medicaid for its testing services has been reinstated as of June 19, 2002, and that all actions against our CLIA certificate have been rescinded. In order to facilitate an immediate
resolution with CMS, we elected to withdraw the appeal of the sanctions we filed with CMS on April 17, 2002, and we will not seek reimbursement for services performed for beneficiaries of
Medicare and Medicaid during the sanction period of February 22, 2002 through June 19, 2002. However, because CMS had imposed its sanctions retroactively to February 22, 2002, we
had billed Medicare and Medicaid programs for some services before we were notified of the actual
imposition of the sanctions by CMS on April 12, 2002. We have sought guidance from CMS as to how the period of retroactive sanctions should be treated, and we have set aside and reserved those
Medicare or Medicaid payments from the period of February 22, 2002 through April 12, 2002 until we receive additional guidance from CMS. We did not challenge CMS' imposition of a
monetary fine of $351,000. We believe that the cancellation of our approval to receive Medicare and Medicaid payments for services performed from February 22, 2002 through June 19, 2002
did not affect testing for Medicare and Medicaid patients for whom we bill our hospital and other clients, but instead applies only to testing for which we bill the Medicare and Medicaid programs
directly. However, we can provide no assurances that the CMS will not seek to prevent our clients from being reimbursed for services we performed during the period from February 22, 2002
through June 19, 2002.

If we lose key personnel or cannot recruit additional personnel, our business may suffer.

We depend substantially on the continued services and performance of our senior management, particularly Douglas S. Harrington, M.D., our chief executive officer
and laboratory director, and certain other key personnel. The loss of the services of any of these executive officers or other key employees could hurt our business.

We
have employment agreements with many of our executive officers, including Dr. Harrington. However, most members of our current senior management group have been recruited and
hired over the past three years. These individuals may not be able to fulfill their responsibilities adequately and may not remain with us.

Our
future success also depends on our ability to identify, attract, hire, train, retain and motivate other highly skilled technical, managerial, marketing and customer personnel,
including California licensed laboratory scientists. Competition for such personnel is intense. We may not be able to attract, assimilate or retain sufficient qualified personnel. In particular, we
may encounter difficulties in attracting a sufficient number of qualified California licensed laboratory scientists. Additionally, we may not be able to retain and attract necessary highly skilled
technical, managerial, marketing and customer

29

personnel at our planned new laboratory and operational headquarters facility in Valencia, California, which is approximately 30 miles from our current location in Santa Monica, California. The
failure to retain and attract necessary personnel could hurt our business and impair our growth strategy.

Our planned move to a new facility in Valencia, California may divert management attention and may lead to disruptions in our operations and service to our customers.

As we previously reported, we are constructing a 195,000 square foot facility in Valencia, California that will enable us to consolidate all of our laboratory and
administrative functions in one location. The
location of the new facility is approximately 30 miles from our current location in Santa Monica, California.

Moving
our entire laboratory and administrative functions to a new location is a time-consuming and complicated process, and includes physically moving and setting up
delicate and complex laboratory equipment over a short period of time, transferring specimens and reagents from one facility to another, changing processes and procedures for delivery of testing
specimens, ensuring that we have adequate staffing of laboratory and administrative personnel at the new facility, and continuing to conduct our testing of specimens during the process. If we are
unable to execute the move to Valencia effectively and efficiently, it could result in short-term service disruptions that would negatively affect our business and could reduce our
revenue. Such service disruptions could also result in customer dissatisfaction, and could materially hurt our business if our customers decided not to purchase our services any longer as a result of
the service disruptions. Furthermore, planning for the move of our facility is also expected to divert the attention of key management personnel.

In
October 2002 we announced that we would postpone the move to our new Valencia facility until the first half of 2004. While the delay will allow us to focus on rebuilding client
confidence and stabilizing our business, and minimize disruptions in service to our customers, we can provide no assurances that key Company management will not be distracted by planning for the
facility move. We can also provide no assurances that we will be able to complete the move to the new Valencia facility efficiently or effectively, or on time, or that we will not experience service
disruptions, loss in customers, or decreased revenue as a result of the move. Because the new Valencia facility is located 30 miles away from our current headquarters, some of our key employees may
choose not to remain employed with us after the move. In addition, because one of the leases to the buildings we currently occupy in Santa Monica, California expires in the first quarter 2004, we will
need to extend or renegotiate our current lease. We can provide no assurance that we will be able to obtain lease extensions on commercially reasonable terms, if at all. The occurrence of any of the
foregoing events affecting or resulting from our move could harm our business.

We may decide to further postpone or cancel our planned move to a new facility in Valencia, which could create financial liabilities.

We are postponing the move to our new Valencia facility until the first half of 2004, to focus on rebuilding client confidence and stabilizing our business, and
minimize disruptions in service to our customers. During the period that the facility construction is postponed, we will incur certain charges for maintenance and security of the site and facility
that could be as much as $400,000 per quarter. We have negotiated certain amendments to the agreement for construction of the new facility with our primary construction partners. The amendments call
for the construction of the facility to be resumed no later than December 31, 2003. If we do not provide notice of our intent to resume construction prior to that date, the agreement for
construction of the facility will be deemed terminated, and we could be subject to termination costs and penalties to our construction partners and subcontractors, which could be in excess of
$2.5 million. In addition, failure to resume construction by December 31, 2003 may impair the existing value of the facility, and we may have to incur certain write-downs of the asset
value.

30

---

We
expect to decide whether and when to recommence the facility's construction sometime in the last half of 2003. We can provide no assurances that we will be able to obtain financing on
favorable terms to fund construction of the new facility, that we will have the ability to complete a move to a new facility without incurring disruptions in service to our customers and loss of
client confidence, or that we will need a larger facility for our operations in light of our reduced testing volume and employee headcount. Based on these and other factors, it is possible that we may
never recommence construction of the new facility in Valencia, or decide to recommence construction after December 31, 2003, and we could thus be liable for the termination costs and penalties
noted above. If we do not resume construction on or before December 31, 2003, our business may be harmed, our assets may be impaired, and our stock price may fluctuate.

If group purchasing organizations do not renew and maintain our contracts, we may lose an important mechanism by which to further penetrate the hospital customer base.

Many of our existing and potential hospital customers are part of group purchasing organizations, which typically pool independent hospitals together to negotiate
for pricing and services, including prices for laboratory tests. These group purchasing organizations provide incentives to their participating hospitals to utilize clinical laboratories which have
contracts with the group purchasing organizations.

Our
participation in group purchasing organizations constitutes one aspect of our overall strategy to attract new hospital customers. We have contracts with several group purchasing
organizations: AmeriNet, MedAssets HSCA (formerly Health Services Corporation of America), Managed Healthcare Associates (MHA), and Shared Services Healthcare (now affiliated with MedAssets HSCA). We
are typically granted non-exclusive provider status under these contracts. Our contracts with our group purchasing organizations will expire at various times from 2003 to 2006. On
May 1, 2002, we announced that Novation, a national purchasing group for hospitals, has discontinued its service agreement with us. The termination of the agreement was without cause and was
effective on July 29, 2002. The original agreement was initiated on May 1, 2001 and provided Novation members with access to discounted clinical laboratory services from us. While we
have experienced some loss of Novation clients, the exact consequences of the agreement's termination are difficult to quantify, particularly since the termination of the contractual relationship with
Novation does not prevent its members from using our services, and it may take a significant period of time before any individual Novation member decides to stop utilizing our services.

Through
the contract termination date of July 29, 2002, sales of our services to hospitals utilizing the Novation group purchasing organization contract comprised
$21 million, or approximately 15% of net revenue for the year ended December 31, 2002. Sales of our services to hospitals utilizing the pricing structures under the AmeriNet group
purchasing organization contract, comprised approximately
$9 million during the year ended December 31, 2002, or approximately 6% of our net revenue. Sales to hospitals within the other three group purchasing organizations comprised
approximately 3% of our net revenues for the same period. These group purchasing organizations offer a substantial growth opportunity to gain additional revenue from existing hospital customers.

We
cannot be certain that the termination of our agreement with Novation will not affect our ability to retain any of the accounts of participating hospitals. We have entered into direct
agreements with many Novation members to provide them with laboratory services, but we cannot predict that we will be successful in entering into any additional such agreements, or that if our
agreement with AmeriNet or any other group purchasing organization is terminated or not renewed, we will be able to retain any of the accounts of their participating hospitals. If any hospital
customer affiliated with a group purchasing organization no longer uses our services, it will reduce our net revenue. In addition, if we are unable to attract new hospital customers because any group
purchasing organization contract is terminated, it may adversely affect our ability to grow our business.

If advances in technology allow others to perform assays similar to ours, the demand for our assays may decrease.

The esoteric clinical laboratory industry is characterized by advancing technology which may enable other clinical laboratories, hospitals, physicians or other
medical providers to perform assays with properties similar to ours in a more efficient or cost-effective manner than is currently possible. Such technological advances may be introduced
by, not just our competitors, but by any third party. For instance, a diagnostic manufacturing company may release an instrument or technology that would make it cost-effective for our
customers to perform esoteric assays internally, rather than through us. If these or other advances in technology result in a decreased demand for our assays, our assay volume and net revenue would
decline.

If we do not comply with laws and regulations governing the confidentiality of medical information, it will adversely affect our ability to do business.

The confidentiality of patient medical information 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 information. Most states have laws that govern the use and disclosure of patient medical information and the right to
privacy. Similarly, many federal laws also may apply to protect such information, including the Electronic Communications Privacy Act of 1986 and federal laws relating to confidentiality of mental
health records and substance abuse treatment.

Legislation
governing the dissemination and use of medical information is continually being proposed at both the state and federal levels. For example, the Health Insurance Portability
and Accountability Act of 1996, known as HIPAA, requires the Secretary of Health and Human Services (HHS) to develop regulations to protect the security and privacy of individually identifiable health
information that is electronically transmitted or received. In November 1999, the Secretary of HHS published proposed regulations under the HIPAA that would protect the privacy of individually
identifiable health information that is transmitted or received electronically, and in August 2002 the Secretary of HHS published the final privacy regulations. Previously, the Secretary of HHS
published proposed regulations relating to security of individually identifiable health information. When and if the security regulation becomes final, and if the privacy regulation is not modified by
HHS or invalidated by Congress under the Congressional Review Act, then they will require that holders or users of electronically transmitted patient health information implement measures to maintain
the security and privacy of such information. Ultimately, this and other legislation may even affect the dissemination of medical information that is not individually identifiable. Physicians and
other persons providing patient
information to us are also required to comply with these laws and regulations. If a patient's privacy is violated, or if we are found to have violated any state or federal statute or regulation with
regard to the confidentiality, dissemination or use of patient medical information, we could be liable for damages, or for civil or criminal fines or penalties. In most circumstances, entities covered
by HIPAA (including us) must be in compliance with the final HIPAA privacy regulations by April 14, 2003.

The
commercialization of our Internet products including Outreach Express®, DataPassportMD®, and DataPassport Clinical Trials is strictly governed by
state and federal laws and regulations, including the new and proposed regulations under HIPAA. We have implemented encryption technology to protect patient medical information, however, use of
encryption technology does not guarantee the privacy and security of confidential information. We believe that we are in material compliance with all currently applicable state and federal laws and
regulations governing the confidentiality, dissemination and use of medical record information. However, differing interpretations of existing laws and regulations, or the adoption of new laws and
regulations, could reduce or eliminate our ability to obtain or use patient information which, in turn, could limit our ability to use our information technology products for electronically
transmitting patient data. While we believe we will be in compliance in all material respects with the HIPAA regulations when such regulations become

32

---

effective, our failure to comply could subject us to fines and penalties, and have a detrimental effect on our business. We can provide no assurances that we will be fully compliant with HIPAA or
other related laws and regulations when such laws and regulations become effective.

We are controlled by a single existing shareholder, whose interests may differ from other shareholders' interests.

Our principal shareholder is Specialty Family Limited Partnership, whose sole general managing partner, James B. Peter, M.D., Ph.D., is a director of the Company.
Specialty Family Limited Partnership, together with Dr. Peter, currently beneficially own approximately 64% of the outstanding shares of our common stock. Accordingly, the Specialty Family
Limited Partnership along with Dr. Peter will have significant influence in determining the outcome of any corporate transaction or other matter submitted to the shareholders for approval,
including election of directors, mergers, consolidations and the sale of all or substantially all of our assets. Our principal shareholder will also have the power to prevent or cause a change in
control. The interests of this shareholder may differ from other shareholders' interests. In addition, this concentration of ownership may delay, prevent, or deter a change in control and could
deprive other shareholders of an opportunity to receive a premium for their common stock as part of a sale of our business.

The premium prices that we initially charge for new assays may drop if our competitors are able to develop and market competing assays more quickly than they currently do.

Typically, we market new esoteric assays at premium prices for several years before similar assays are developed as either standardized prepared kits for broad
application or as internally developed assays
by competing laboratories. The opportunity to sell our products at premium prices may be reduced or eliminated if our competitors are able to develop and market competing assays more quickly than they
currently do. If we are unable to develop newer assays which meet market demand, our net revenue and profit margins may decrease.

If we are unable to develop and successfully market new assays or improve existing assays in a timely manner, our profit margins may decline.

In order to maintain our margins and benefit from the premium prices that we typically charge for our newly introduced esoteric assays, we must continually
develop new assays and improve our existing assays through licensing arrangements with third parties and through the efforts of our R&D department. There is no assurance, however, that we will be able
to maintain our current pace of developing and improving assays in the future. Even if we develop such assays in a timely manner, our customers may not utilize these new assays. If we fail to develop
new technologies, release new or improved assays on a timely basis, or if such assays do not obtain market acceptance, our profit margins may decline.

If we fail to acquire licenses for new or improved assay technology platforms, we may not be able to accelerate assay improvement and development, which could harm our ability
to increase our net revenue.

Our ability to accelerate new assay development and improve existing performance will depend, in part, on our ability to license new or improved assay technology
platforms on favorable terms. We may not be able to negotiate acceptable licensing arrangements and we cannot be certain that such arrangements will yield commercially successful assays. Further, even
if we enter into such arrangements with these third parties, their devotion of resources to these efforts may not be within our control or influence. If we are unable to license these technologies at
competitive rates, our research and development costs may increase. In addition, if we are unable to develop new or

33

---

improved assays through such research and development efforts, our assays may be outdated when compared with our competition's assays, and our net revenue may decrease.

Failure in our information technology systems could significantly increase turn-around time, reduce our production capacity, and otherwise disrupt our operations,
which may reduce our customer base and result in lost net revenue.

Our success depends, in part, on the continued and uninterrupted performance of our information technology systems, including our DataPassport® suite
of products. Sustained or repeated system failures that interrupt our ability to process assay orders, deliver assay results or perform assays in a timely manner would reduce significantly the
attractiveness of our products to our customers. Our business,
financial condition, results of operations, or cash flows could be materially and adversely affected by any damage or failure that interrupts or delays our operations.

Our
computer systems are vulnerable to damage from a variety of sources, including telecommunications failures, malicious human acts and natural disasters. Moreover, despite reasonable
security measures we have implemented, some of IT systems are potentially vulnerable to physical or electronic break-ins, computer viruses and similar disruptive problems, in part because
we conduct business on the Internet and because some of these systems are located at third party web hosting companies, Exodus Communications, in El Segundo, California, and Qwest Communications in
Burbank, California, and we cannot control the maintenance and operation of the Exodus and Qwest data centers. Despite the precautions we have taken, unanticipated problems affecting our systems could
cause interruptions in our information technology systems, leading to lost revenue, deterioration of customer confidence, or significant business disruption.

We
have several different insurance policies designed to cover losses arising from such interruptions. However, these insurance policies may not adequately compensate us for any losses
that may occur due to any failures in our systems.

Change of our web hosting company from Exodus Communications to another provider of services could result in a disruption of our operations, and our business, results of
operations and financial condition could be materially and adversely affected by any damage or failure that interrupts or delays our operations.

Some of our IT systems are located at third party web hosting companies, Exodus Communications, in El Segundo, California and Qwest Communications in Burbank,
California. Exodus Communications filed for Chapter 11 bankruptcy protection in September of 2001, and certain assets of Exodus have been acquired by Cable & Wireless plc. While the Exodus
operations have so far continued uninterrupted, and not yet affected any of our operations, we are in the process of changing our network server hosting service to Qwest. We expect to complete the
move to Qwest sometime in the first half of 2003.

We
cannot guarantee that our operations will be unaffected by Exodus' bankruptcy, or the asset purchase by Cable & Wireless. Furthermore, the actions of transferring our network
service hosting to Qwest could result in interruption and or delays in our operations. While we are building a parallel system at Qwest, and are taking other precautions to prevent any such
interruption or delay in our operations, we cannot guarantee that the act of moving to a different service provider will not result in such interruptions or delays in our operations. Moreover, despite
changing web-hosting providers, some of our servers will remain potentially vulnerable to physical or electronic break-ins, computer viruses and similar disruptive problems, in
part because they will remain at a third party web hosting company, and we cannot control the maintenance and operation of the data centers. Despite the precautions we have taken, unanticipated
problems affecting our systems could cause interruptions in our information

34

---

technology systems. Our business, financial condition, results of operations, or cash flows could be materially and adversely affected by any problem that interrupts or delays our operations.

While
we have insurance policies that may cover losses arising from such interruptions, these insurance policies may not adequately compensate us for any losses that may occur due to any
failures in our systems as a result of moving to a new provider, or any losses that may occur due to any failures in our systems.

If we lose our competitive position in providing valuable information technology solutions as an ancillary service to our customers, we may not be able to maintain or grow our
market share.

Over the past five years, we have made a substantial investment in our information technology solutions, such as DataPassport®,
DataPassportMD®, and Outreach Express®, to facilitate electronic assay ordering and results reporting as a value added service for our customers. We believe that these
solutions are one factor considered by our customers when selecting a reference laboratory. In the future, our competitors may offer similar or better information technology solutions to our existing
and potential customer base. If this occurs, we will lose this competitive advantage, and as a result, may be unable to maintain or increase our market share.

We rely on a few assays for a significant portion of our net revenue. If demand for these assays were to weaken for any reason, our net revenue would decrease.

A significant portion of our net revenue is derived from 30 assays. Net revenue from these 30 assays comprised approximately 45% of our total net revenue for the
year ended December 31, 2002. If competing assays are introduced by competitors or demand for these assays otherwise decreases, our net revenue could decrease.

Clinicians or patients using our products or services may sue us and our insurance may not sufficiently cover all claims brought against us, which will increase our expenses.

The development, marketing, sale and performance of healthcare services expose us to the risk of litigation, including professional negligence. Damages assessed
in connection with, and the costs of defending, any legal action could be substantial. We currently maintain insurance with coverage up to $15 million, either singly or in the aggregate, which
we believe to be adequate to cover our exposure in our current professional liability claims and employee-related matters which were incurred in the ordinary course of business. Although we believe
that these claims may not have a material effect on us, because we expect them to be covered by this insurance, we may be faced with litigation claims which exceed our insurance coverage or are not
covered under our insurance policy. In addition, litigation could have a material adverse effect on our business if it impacts our existing and potential
customer relationships, creates adverse public relations, diverts management resources from the operation of the business or hampers our ability to perform assays or otherwise conduct our business.

If protection of the intellectual property underlying our technology and trade secrets is inadequate, then third parties may be able to use our technology or similar
technologies, thus reducing our ability to compete.

We currently rely on certain technologies for which we believe patents are not economically feasible and therefore may be developed independently or copied by our
competitors. Furthermore, we rely on certain proprietary trade secrets and know-how, which we have not patented. Although we have taken steps to protect our unpatented trade secrets and
know-how, principally through the use of confidentiality agreements with our employees, there can be no assurance that these agreements will not be breached, that we would have adequate
remedies for any breach, or that our trade secrets will not otherwise become known or be independently developed or discovered by competitors. If our trade

35

---

secrets become known or are independently developed or discovered by competitors, it could have a material adverse effect on our ability to compete.

Our assays may infringe on the intellectual property rights of others, which may cause us to engage in costly litigation which may cause us to pay substantial damages and
prohibit us from selling our assays.

Other companies or institutions engaged in assay development, including our competitors, may obtain patents or other proprietary rights that would prevent, limit
or interfere with our ability to develop, perform or sell our assays. As a result, we may be found to be, or accused of, infringing on the proprietary rights of others. For example, in response to a
patent infringement allegation from Athena Diagnostics in 1997, we ceased performing an assay used to diagnose late onset Alzheimer's disease. We have received letters from Chiron Corporation in
February 1998, and from the National Institute of Health (NIH) in 2000, 2001, and 2002 claiming that some of our assays may violate their patents. While neither NIH nor Chiron has filed suit
against us, we cannot provide any assurances that they will not do so in the future. We intend to defend any such suit that may arise vigorously and to assert all available defenses to allegations of
patent infringement that would be available to us. Such suits could be expensive to defend and could divert management's time and resources, regardless of the merit or validity of any such suit.
Furthermore, we cannot provide any assurances that we would be successful in defending any such suit, and there can be no assurance that there will be no adverse consequences to us. As a result of
these claims and any other infringement related claims, we could incur substantial costs in defending any litigation, and intellectual property litigation, or the threat of such litigation, could
force us to do one or more of the following:



We
can provide no assurances that we will be able to secure licenses for such patents on commercially reasonable terms, if at all. Any efforts to reengineer our assays or any inability
to sell our assays, or an obligation to pay license fees and royalties could substantially increase our costs, force us to interrupt product sales, delay new assay releases, decrease our
competitiveness in the marketplace, reduce our revenues, and materially impair our business. In addition, if a suit were brought against us alleging patent infringement, and we were found to have
infringed the patents at issue, including those of NIH and of Chiron, we could be forced to pay substantial damages, including possible treble damages for allegations of willful infringement. While we
intend to defend any such suit vigorously, and assert all available defenses, we cannot provide any assurances that we would be successful in defending any such suit. If we were to lose such a suit,
it could create a material financial liability, negatively affect our operating results, and negatively impact our stock price.

We may acquire other businesses, products or technologies in order to remain competitive in our market and our business could be adversely affected as a result of any of these
future acquisitions.

We have made in the past and we may continue to make acquisitions of complementary businesses, products or technologies. In this regard, we acquired BBI Clinical
Laboratories, Inc. in February 2001. If we identify any additional appropriate acquisition candidates, we may not be successful in negotiating acceptable terms of the acquisition,
financing the acquisition, or integrating the acquired business, products or technologies into our existing business and operations. Further, completing an acquisition and integrating an acquired
business will significantly divert management time and resources. The diversion of management attention and any difficulties encountered in the transition and integration process could harm our
business. If we consummate any significant acquisitions using stock or other

36

---

securities as consideration, your equity in us could be significantly diluted. If we make any significant acquisitions using cash consideration, we may be required to use a substantial portion of our
available cash. Acquisition financing may not be available on favorable terms, if at all. In addition, we may be required to amortize significant amounts of other intangible assets in connection with
future acquisitions, which would harm our operating results.

We may encounter problems or delays in operating or implementing our automated processing systems, which could disrupt our operations, require us to develop alternatives and
increase our costs.

In order to meet growth in demand for our esoteric assays, we will have to process many more patient samples than we are currently processing. We have implemented
a high-speed specimen sorting system known as the Total Accessioning Re-Organization System, or TARO, and a specimen splitting system, known as the Harmonized
Assignment of Nanoliter Aliquots, or HANA. In addition, we plan to develop and implement other automated systems to enhance our testing procedures. We will need to develop sophisticated
software to support these other automated procedures, analyze the data generated by these tests and report the results. Further, as we attempt to increase the number of patient samples we process,
throughput or quality-control problems may arise.

If
we are unable to consistently process patient samples on a timely basis because of delays or failures in our implementation of these automated systems, or if we encounter problems
with our established automated processes, we will be required to develop alternate means to process our business which may increase our costs.

If a catastrophe were to strike our clinical laboratory facility, we would be unable to process our customers' samples for a substantial amount of time and we would be unable
to operate our business competitively.

Our clinical and processing facility may be affected by catastrophes such as earthquakes or sustained interruptions in electrical service. Earthquakes are of
particular significance to us because all of our clinical laboratory facilities are located in Santa Monica, California, an earthquake-prone area. In the event our existing clinical laboratory
facility or equipment is affected by man-made or natural disasters, we would be unable to process our customers' samples in a timely manner and unable to operate our business in a
commercially competitive manner. To address these risks, we have in place formal recovery plans for such interruptions of service. This includes identification of alternate laboratory testing
facilities and disaster recovery protocols. We also carry earthquake insurance with a coverage amount of up to $20 million and we have outsourced part of our data storage and processing
equipment to a facility designed to withstand most earthquakes. Despite these precautions, the self-insured retention amount for earthquake insurance is very high, and there is no
assurance that we could recover quickly from a serious earthquake or other disaster.

We rely on a continuous power supply to conduct our operations, and California's current energy crisis could disrupt our operations and increase our expenses.

All of our laboratory operations are located in Santa Monica, California and we have been planning to move our operations to Valencia, California. California is
still in an energy crisis that could disrupt our operations and increase our expenses. In the event power reserves for the state of California fall to critically low levels, California may implement
rolling power blackouts throughout the state. The state of California has already experienced such occasional power blackouts. We currently have backup
power generators for our laboratories in the event of a blackout. Our current insurance, however, does not provide coverage for any damages we may suffer as a result of any interruption in our power
supply. If blackouts interrupt our third party power supply, we may be temporarily unable to continue operations. Any such interruption in our ability to continue operations would delay our processing
of laboratory samples, disrupt communications with our customers and suppliers and delay

37

---

product shipment. Power interruptions could also damage our reputation and could result in lost revenue. Any loss of power could have a material adverse effect on our business, operating results and
financial condition. Furthermore, shortages in wholesale electricity supplies have caused power prices to increase. If wholesale prices continue to increase, our operating expenses will likely
increase which will have a negative effect on our operating results.

Disruption
similar to the September 2001 terrorist attacks in the future on the U.S. may adversely impact our results of operations, future growth and stock price.

The
operation of our laboratories has been and may continue to be harmed by the recent terrorist attacks on the U.S. For example, transportation systems and couriers that we rely upon to
receive and process specimens have been, and may in the future be, disrupted. In addition, we may experience a rise in operating costs, such as costs for transportation, courier service, insurance and
security. We may also experience delays in receiving payments from payors that have been affected by the attack, which, in turn, would harm our cash flow. The U.S. economy in general may be adversely
affected by the terrorist attacks or by any related outbreak of hostilities. Any such economic downturn could adversely impact our results of operations, revenues and costs, impede our ability to
continue to grow our business and may result in the volatility of the market price of our common stock and on the future price of our common stock.

Anti-takeover provisions in our charter documents could prevent or delay a change in control and, as a result, negatively impact our shareholders.

We have taken a number of actions that could have the effect of discouraging a takeover attempt. For example, provisions of our amended and restated articles of
incorporation and amended and restated bylaws could make it more difficult for a third party to acquire us, even if doing so would be beneficial to our shareholders. These provisions also could limit
the price that certain investors might be willing to pay in the future for shares of our common stock.

These
provisions include:



ITEM 2. PROPERTIES

Our primary facility is located in Santa Monica, California and is comprised of four separate buildings totaling 85,357 square feet. All four of our building
leases expire in 2004. Additionally, three of our leases have options for additional years upon expiration of the current leases. We are currently negotiating for an option for additional years for
the remaining building. Annual rent for these four buildings is approximately $1.7 million plus applicable property taxes, maintenance costs and utilities.

We
also operate one stand-alone triage collection and processing center in Worcester, Massachusetts to serve Boston area customers. This facility contains 1,578 square feet and is leased
at approximately $50,000 per year on a month-to-month basis. We also occupy a smaller 210 square foot administrative facility at the same address.

In
December 2001, we purchased a 13.8 acre site in Valencia, California. We are constructing a 195,000 square foot facility which will enable us to consolidate all of our
laboratory and administrative functions in one location. The construction project was originally scheduled to be completed in the second half of 2003. In October 2002, we announced that we
would postpone the move to our new facility in Valencia until the first half of 2004 and halt the construction project once the Core and Shell

38

---

of the building were completed. The Core and Shell were substantially completed in January 2003, with the remaining work of punch lists and sign-off of systems to conclude during
February and March 2003. The decision to restart the building project will occur sometime in the second half of 2003. The construction costs have been financed with investments and cash
generated from operations.

We
expect to decide whether and when to recommence the facility's construction sometime in the last half of 2003. We can provide no assurances that we will be able to obtain financing on
favorable terms to fund construction of the new facility, that we will have the ability to complete a move to a new facility without incurring disruptions in service to our customers and loss of
client confidence, or that we will need a larger facility for our operations in light of our reduced testing volume and employee headcount. Based on these and other factors, it is possible that we may
never recommence construction of the new facility in Valencia, or decide to recommence construction after December 31, 2003. If we do not provide notice of our intent to resume construction
prior to that date, the agreement for construction of the facility will be deemed terminated, and we could be subject to substantial termination costs and penalties, which could be in excess of
$2.5 million. For more information, please
see "Risk FactorsWe may decide to further postpone or cancel our planned move to a new facility in Valencia, which could create financial liabilities."

ITEM 3. LEGAL PROCEEDINGS

In addition to the California state and federal investigations described in "BusinessGovernment RegulationCertification and Licenses",
"Risk FactorsOur operations and facilities are subject to stringent laws and regulations and if we are unable to comply, our business may be significantly harmed", and "Management's
Discussion and Analysis of Financial Condition and Results of OperationSubsequent Events", we are involved in various legal proceedings arising in the ordinary course of business.

As
previously reported, in May and June, 2002, we were named as a defendant, together with certain of our current or former board members and officers, in four substantially identical
class-action lawsuits filed in the United States District Court for the Central District of California. In September 2002 an amended and consolidated complaint was filed and is serving as the
operative complaint in this litigation. The lawsuit purports to state claims on behalf of an alleged class of investors who bought our stock in the open market between December 8, 2000 and
April 15, 2002 ("Class Period"). The lawsuit alleges that the market price of our stock was artificially inflated during the Class Period as a result of alleged misrepresentations made in
violation of the Securities Act of 1933 and the Securities Exchange Act of 1934 in connection with our initial public offering of common stock and subsequent public disclosures. The lawsuit alleges,
among other things, false and misleading statements about our compliance with certain regulatory requirements imposed by the California Department of Health Services and the federal Centers for
Medicare & Medicaid Services. Plaintiffs seek compensatory damages, including interest, costs and expenses, attorneys' fees, and other relief. In October 2002 we filed a motion to
dismiss the amended complaint, and in February 2003 the court ruled on the motion, dismissing some claims and not dismissing others. In response to the judge's ruling, we expect plaintiffs to
file an amended complaint in March 2003. We have provided notice to our directors and officer's insurers, and believe that we have insurance applicable to the defense of the lawsuits. We also
believe that the claims against us and our current and former officers and directors are without merit, and intend to defend the lawsuits vigorously.

Also
as previously reported, Specialty Laboratories Asia Pte. Ltd., a Singapore corporation, or SLA, is 60% owned by our wholly-owned subsidiary, Specialty Laboratories
International Ltd., a British Virgin Islands corporation. SLA was headquartered in Singapore but, in early 1999, SLA ceased all operations and is currently insolvent. A former employee of SLA
has obtained a judgment for $350,000 against SLA and a default judgment of approximately $1.95 million in a wrongful termination action against SLA filed by him in Singapore. The former
employee has filed an action against SLA in San

39

---

Diego Superior Court to attempt to collect on the Singapore judgment and has obtained a default judgment of approximately $2.5 million against SLA in California. The former employee served
discovery upon us and certain of our directors and officers. Our management believes that any claim against us or our directors and officers in connection with these judgments, if made, would be
without merit, and we would vigorously defend any such action.

Also
as previously reported, in 2001, one of our former officers filed an action in federal district court in Los Angeles against us and two of our officers alleging violations of
federal and state securities laws and other causes of action in connection with the sale of our common stock by the former officer and our application of our insider trading policy. Our motion to
compel arbitration was granted, and one of the individual defendants has subsequently been dropped from plaintiff's claims. The matter has been submitted to binding arbitration before a former federal
judge, who recently granted the plaintiff a continuance. We expect the matter to be heard by the arbitrator sometime in 2003. Management believes the claims to be without merit and will vigorously
defend this action.

From
time to time, we receive letters alleging infringement of patent or other intellectual property rights. Our management believes that these letters generally are without merit and
intend to contest them vigorously. For more information, please see "Risk FactorsOur assays may infringe on the intellectual property rights of others, which may cause us to engage in
costly litigation which may cause us to pay substantial damages and prohibit us from selling our assays."

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

The following discussion of our financial condition and results of operations should be read in conjunction with our selected consolidated financial data and the consolidated
financial statements and related notes included elsewhere in this Annual Report. This section includes forward-looking information that involves risks and uncertainties. Our actual results could
differ materially from those anticipated by forward-looking information due to factors discussed under "Risk Factors," "Business" and elsewhere in this Annual Report.

For a complete definition of EBITDA please see footnote 7 under "Selected Consolidated Financial Data."

Overview

We are a leading hospital-focused clinical laboratory, performing highly advanced, clinically useful testing services for hospitals, laboratories and physician
specialist communities nationwide. We believe we offer the most comprehensive menu of esoteric assays in the industry, with a test menu of more than 2,500 assays. Many of our tests have been developed
through our internal research and development efforts. Esoteric assays are complex, comprehensive or unique tests used to diagnose, evaluate and monitor patients. These assays are often performed on
sophisticated instruments by highly skilled personnel and are therefore offered by a limited number of clinical laboratories.

Our
primary customers are hospitals, independent clinical laboratories and physicians. We have aligned our interests with those of hospitals, our fastest growing client segment, by not
competing in the routine test market that provides them with a valuable source of revenue. We educate physicians on the clinical value of our assays through our information-oriented marketing
campaigns. Our technical, experienced sales force concentrates on the hospitals and independent laboratories that serve as distribution channels for physician assay orders. We use our advanced
information technology solutions to accelerate and automate electronic ordering and results reporting with these customers.

Through
the execution of our hospital-focused strategy, we grew rapidly in recent years. For the three years 1999 through 2001, our net revenue grew at a compounded annual growth rate of
16%. This growth was supplemented with the acquisition of BBI Clinical Laboratories, Inc., in the first quarter of 2001. BBI Clinical Laboratories, a private company founded in 1989, was a
leading esoteric clinical reference laboratory specializing in infectious disease testing, such as Lyme disease and viral hepatitis. BBI Clinical Laboratories' primary customers included hospitals,
physician specialists, pharmaceutical and diagnostic companies, and other clinical and research laboratories.

While
the core hospital-focus strategy remains the same, 2002 was marked by two significant eventsthe regulatory actions taken by the California Department of Health
Services (CDHS) and the federal Centers for Medicare & Medicaid Services (CMS) in March and April 2002, and the announcement of the acquisition of Unilab Corporation, our largest
customer, by Quest Diagnostics Inc., one of our competitors. As a result of these events, we have experienced a significant reduction in revenues for 2002. These events are discussed below.

By
letter dated March 28, 2002, CDHS notified us of its intent to impose sanctions of a directed plan of correction, random onsite monitoring, and a civil money penalty based upon
deficiencies cited on November 28, 2001 following laboratory inspections conducted during June and October 2001. The sanctions were based on findings that we were permitting unlicensed
personnel to perform and supervise clinical laboratory testing in violation of California law. We filed supplemental documentation supporting our compliance with the applicable requirements with CDHS
and CMS on April 26, 2002. In addition, on April 26, 2002, we requested that CDHS rescind its proposed sanctions outlined in the March 28, 2002 letter based on our supplemental
submission. In May and June 2002, CDHS conducted additional unannounced inspections, and we provided additional documentation supporting our

44

---

compliance with CDHS requirements. By letter dated June 28, 2002, and amended on July 18, 2002, CDHS indicated that we were in substantial compliance with California clinical laboratory
law. CDHS also imposed sanctions of a civil money penalty of $1,000 per day for 344 days (i.e., $344,000), plus $20,430 for the cost of conducting their investigations, and imposed onsite
monitoring for three years, including unannounced inspections. We did not appeal these imposed sanctions.

By
letter dated April 12, 2002, CMS notified us of its conclusions regarding laboratory inspections in June and October 2001 conducted by CDHS. CMS concluded that our
February 2002 response to deficiencies detected in the inspections did not constitute a credible allegation of compliance. As a result, CMS imposed certain sanctions, including notice of
revocation of our Clinical Laboratory Improvement Act (CLIA) certificate, cancellation of our approval to receive Medicare and Medicaid payments for services performed, imposing a civil money penalty
of $3,000 per day for each day during the sanction period, and imposing a directed plan of correction by which CMS could notify our customers of our non-compliance and the nature and
effective date of any sanctions imposed. We filed an appeal to the CMS action on April 17, 2002, and the appeal stayed the revocation of our CLIA certificate during our administrative appeal.
The cancellation of Medicare and Medicaid payments was effective for services performed by us on and after February 22, 2002. On July 17, 2002, CMS notified us that it had deemed
Specialty in compliance with all condition level requirements of CLIA as of June 19, 2002, that Specialty's ability to bill Medicare and Medicaid for its testing services has been reinstated as
of June 19, 2002, and that all actions against our CLIA certificate were rescinded. In order to facilitate an immediate resolution with CMS, we elected to withdraw the appeal of the sanctions
we filed with
CMS on April 17, 2002, and we will not seek reimbursement for services performed for beneficiaries of Medicare and Medicaid during the sanction period of February 22, 2002 through
June 19, 2002. However, because CMS had imposed its sanctions retroactively to February 22, 2002, we had billed Medicare and Medicaid programs for some services before we were notified
of the actual imposition of the sanctions by CMS on April 12, 2002. We have sought guidance from CMS as to how the period of retroactive sanctions should be treated, and we have set aside and
reserved those Medicare or Medicaid payments from the period of February 22, 2002 through April 12, 2002 until we receive additional guidance from CMS. We did not challenge CMS'
imposition of a monetary fine of $351,000, representing $3,000 per day during the sanction period. We believe that the cancellation of our approval to receive Medicare and Medicaid payments for
services performed from February 22, 2002 through June 19, 2002 did not affect testing for Medicare and Medicaid patients for whom we bill our hospital and other clients, but instead
applies only to testing for which we bill the Medicare and Medicaid programs directly.

On
April 2, 2002, Quest Diagnostics, Inc. announced that they had entered into a definitive agreement to acquire Unilab Corporation. Unilab, our largest customer, comprised
approximately 10% and 8% of our net revenue for the years ended December 31, 2002 and 2001, respectively. As a result, Unilab did not renew the three-year agreement with us, which
expired in October of 2002, and we experienced a significant decline in testing volumes sent to us from Unilab after expiration of the contract. In October 2002, we entered into a new agreement
with Unilab which should allow for a more orderly reduction of the remaining test volumes. With the completion of Unilab's acquisition in February 2003, we believe that Quest will perform the
majority of testing previously sent to us by Unilab. In March 2003, Unilab provided us notice that it would stop sending us certain tests covered under the new agreement. While we believe that
there will continue to be a logical wind down of testing sent to us, we do expect it to have a significant negative impact on our accession volumes in 2003.

As
a result of these significant events on our business, on June 18, 2002, we announced a reduction in workforce totaling 10% as part of an overall restructuring plan. The plan
involved all areas and levels of the company. In connection with the restructuring effort, we recorded a charge of approximately $3.6 million in the second quarter of 2002. The charge comprised
severance payments

45

---

and related obligations for employees whose positions were eliminated. During September 2002, as a result of further business review and the refinement of our core strategic business, we
eliminated some employee positions primarily in the area of our clinical trials department. We recorded a restructuring charge of approximately $468,000 in the third quarter of 2002. The charge
comprised severance payments for employees whose positions were eliminated and the write-off of certain assets related to our clinical trials business. In November 2002, in our
continuing efforts to manage costs and align our staff with current business levels, we had a reduction in workforce focused primarily on the laboratory. We recorded a restructuring charge of
approximately $984,000 in the fourth quarter of 2002, which comprised severance payments for employees whose positions were eliminated and for the write-off of certain capitalized costs
associated with the delayed move to our new Valencia facility and the related termination of the synthetic lease financing arrangement with the banking group led by BNP Paribas.

Other
significant developments included:

As
previously reported, in December 2001, we purchased a 13.8 acre site in Valencia, California. We are in the process of building a 195,000 square foot facility which would
enable us to consolidate all of our laboratory and administrative functions in one location. Construction began during the second quarter of 2002 and was to be completed in the second half of 2003. In
October 2002, we announced that we would postpone the move to our new facility in Valencia until the first half of 2004. Accordingly, the construction of the new facility will be paused. This
postponement will allow us to focus on rebuilding client confidence and stabilizing our business by minimizing any disruptions in service to our clients based on planning and executing a move to a new
facility during this rebuilding period. We have halted construction at completion of the Core and Shell of the facility, a logical break point, and this phase was substantially completed in
January 2003. Upon restart of the facility construction, we plan to fund completion with traditional construction and mortgage financing. We expect to decide whether and when to recommence the
facility's construction sometime in the last half of 2003. However, we can provide no assurances that we will be able to obtain financing on favorable terms to fund construction of the new facility,
that we will have the ability to complete a move to a new facility without incurring disruptions in service to our customers and loss of client confidence, or that we will need a larger facility for
our operations in light of our reduced testing volume and employee headcount. Based on these and other factors, it is possible that we may never recommence construction of the new facility in
Valencia, or decide to recommence construction after December 31, 2003. If we do not provide notice of our intent to resume construction prior to that date, the agreement for construction of
the facility will be deemed terminated, and we could be subject to substantial termination costs and penalties, which could be in excess of $2.5 million. For more information, please see Risk
Factors"Our planned move to Valencia, California may divert management attention and may lead to disruptions in our operations and service to our customers" and Risk
Factors"We may decide to further postpone or cancel our planned move to a new location in Valencia, which could create financial liabilities."

In
March 2002, we completed a $100 million financing transaction. This credit facility had two components: first, we entered into a 6.5 year lease to finance
construction of our new laboratory and headquarters facility in Valencia, California, sometimes referred to as a "synthetic lease", with a total cost, including financing costs, of up to
$60 million, and second, we entered into a $40 million line of credit with the same lenders that provided the lease financing, with proceeds available for general corporate purposes.
Prior to this transaction, we had an existing line of credit of $30 million, which was provided by Union Bank of California. The new credit facility, arranged by BNP Paribas, included Union
Bank, US Bank, First Union National Bank, as co-syndication agents, and Allied Irish Banks, Manufacturers Bank, and Bank Leumi, USA, as participants. As a result of our decision to pause
construction of the Valencia facility and our desire to have on balance sheet financing, we exercised our purchase option in the fourth quarter 2002 under the lease finance agreement, paying off the
debt so

46

---

we can obtain title to the ground lease and facility improvements, thus ending the synthetic lease. Subsequently, we also terminated our line of credit with this bank group.

On
April 22, 2002, James B. Peter, M.D., Ph.D., resigned from the positions of chairman and chief executive officer. On May 21, 2002, we announced that Douglas S.
Harrington, M.D. was named chief executive officer. Dr. Harrington has more than 18 years of laboratory services and diagnostic devices industry experience. He served as chief executive
officer of ChromaVision Medical Systems from 1996 to 2001, held various executive positions at Nichols Institute including president and laboratory director, is board certified in anatomic, clinical
pathology and hematology, and is fully licensed as a Clinical Laboratory Director. Dr. Harrington has served on our board of directors since 1996. As
announced on April 22, 2002, Thomas R. Testman was elected by our board of directors to serve as chairman. Mr. Testman, a retired managing partner with Ernst & Young since 1992,
has served on our board of directors since 1996.

On
May 1, 2002, we announced that Novation, a national purchasing group for hospitals, discontinued its service agreement with us. The termination of the agreement was without
cause and was effective on July 29, 2002. The original agreement was initiated on May 1, 2001 and provided Novation members with access to discounted clinical laboratory services from
us. While we have experienced some loss of Novation clients, the exact consequences of the agreement's termination are difficult to predict, particularly since the termination of the contractual
relationship with Novation does not prevent its members from using our services, and it may take a significant period of time before any individual Novation member decides to stop utilizing our
services.

On
June 24, 2002, we announced the appointment of Terrance H. Gregg to our board of directors. Mr. Gregg, former president of Medtronic MiniMed, brings more than
20 years of healthcare experience to the board. He assumes the board seat vacated by Paul F. Beyer who resigned as our president and chief operating officer as announced on June 7, 2002.

On
July 23, 2002, we announced the appointment of Mark R. Willig to the position of Vice President, Sales. Mr. Willig has nearly 20 years of experience in the
diagnostics and clinical reference laboratory industries, and more recently served as Vice President of Sales at Myriad Genetics from 1997 until joining Specialty.

On
October 12, 2002, we announced that John C. Kane resigned from our Board of Directors.

On
November 6, 2002, we announced the appointment of Michael C. Dugan, M.D. to the position of Vice President and Co-Laboratory Director. Dr. Dugan previously
served as Chief of Pathology and Medical Director of Clinical Laboratories at Santa Monica UCLA Medical Center and has held multiple staff appointments as part of the Affiliated Pathologists Medical
Group, one of the largest pathology groups in California.

Critical Accounting Policies

Revenue Recognition

Revenue is recognized as services are rendered upon completion of the testing process for a specific customer order for which we have no future performance
obligation to the customer, the customer is obligated to pay and the fees are non-refundable. Our revenue recognition policies are in compliance with Securities and Exchange Commission
Staff Accounting Bulletin No. 101.

Services
are provided to certain patients covered by various third-party payor programs including Medicare and Medicaid. Billings for services under third-party payor programs are
included in net revenue net of allowances for differences between the amounts billed and estimated receipts under such programs. Adjustments to the estimated payment amounts based on final settlement
with the third-party payor programs are recorded upon settlement. During the second quarter of 2002, we did

47

---

not recognize any net revenue related to Medicare and Medicaid services; this is a result of CMS canceling our approval to receive Medicare and Medicaid payments for services performed during the
sanction period of February 22, 2002 through June 19, 2002. With the resolution of sanctions imposed by CMS, in the third quarter of 2002, we resumed the recognition of net revenue
related to Medicare and Medicaid services performed subsequent to June 19, 2002.

Expense Recognition

Expenses are recognized as incurred and are generally classified as cost of services or selling, general and administrative expenses. Components of cost of
services include salaries and employee benefits, research and development costs, supplies and reagents, courier costs, depreciation of laboratory equipment and leasehold improvements. Selling, general
and administrative expenses include salaries and employee benefits, sales and marketing, information technology, insurance and bad debt expense.

Stock-Based Compensation Charges

Stock-based compensation charges represent the difference between the exercise price of options granted, or the price of stock sold to employees and directors,
and the deemed fair value of our common stock on the date of grant or sale in accordance with Accounting Principles Board Opinion No. 25 and its related interpretations. In the case of options,
we recognize this compensation charge over the vesting periods of the options using an accelerated amortization methodology in accordance with Financial Accounting Standards Board Interpretation
No. 28. For purposes of the period-to-period comparisons included in "Results of Operations," selling, general and administration expenses exclude these stock-based
compensation charges, which are reflected as a separate line item.

We
have recorded deferred stock-based compensation related to unvested stock options granted to employees and directors. Based on the number of outstanding options granted as of
December 31, 2002, we expect to amortize approximately $94,000 of deferred stock-based compensation in future periods. We expect to amortize this deferred stock-based compensation approximately
as follows: $81,000 during 2003, and $13,000 during 2004. We anticipate that the exercise price of stock options granted after the calendar year of 2000 will be at the reported market price of our
common stock, and therefore no deferred stock-based compensation will result from these grants.

Results of Operations

The following table sets forth the percentage of net revenue represented by certain items in our consolidated statements of operations.

Year Ended December 31, 2002 Compared with Year Ended December 31, 2001

Net Revenue

Net revenue decreased approximately $35.0 million, or 20.0%, to $140.2 million for the year ended December 31, 2002 from
$175.2 million for the year ended December 31, 2001. Revenues for the current year were impacted primarily from the loss of customers and reduction of customer volumes as a result of the
uncertainty related to our regulatory matters that were resolved in the third quarter of 2002. The reduction in revenues occurred across our entire customer mix, but was most significant in business
from other independent laboratories (excluding Unilab, our largest customer) and physician direct business, which declined by approximately 30%, while testing referred from our hospital clients
declined approximately 13%. In addition, as a part of the sanctions imposed by the Centers for Medicare & Medicaid Services (CMS), we were suspended from receiving reimbursement for Medicare
and Medicaid services for the period of February 22, 2002 through June 19, 2002, and $2.3 million of net revenue for these services was not recognized in the year. While our
regulatory matters were resolved in the third quarter of 2002, and we believe that the significant customer volume loss related to this matter has ended, the recently completed acquisition of Unilab,
our largest customer comprising approximately 10% of our revenues in 2002, by Quest Diagnostics will result in a further decline in total revenues in 2003, and this decline could be significant. On
March 3, 2003, Unilab provided us notice that it would stop sending us certain tests covered under a new agreement we reached with them in October 2002.

The
year over year revenue decline is reflected in a drop in accession volumes of approximately 8%, as accessions were nearly 2.9 million for the year ended December 31,
2002 as compared to more than 3.1 million for the prior year. This volume decline is coupled with a year over year decline in the aggregate average selling price of nearly 13%. This drop in the
aggregate average selling price is due primarily to our continued client mix-shift towards hospital-based business and the reduction in independent laboratory business, as revenues from
hospitals grew to nearly 61% of total revenues for the year ended December 31, 2002 as compared to approximately 56% for the year ended December 31, 2001. With our continued focus on
growing our hospital client base, coupled with the expected loss of business from Unilab during 2003, we expect a further decline in the aggregate average selling price for 2003, but at a much more
modest rate. This projected decrease, however, is dependent on a number of factors, including, but not limited to, the rate of loss of Unilab business, no additional significant losses of other
independent laboratory business, and any significant change in price competition within the hospital market.

Cost of Services

Cost of services, which includes costs for laboratory operations, distribution services, and research and development, increased approximately
$4.4 million, or 4.4%, to $104.4 million for the year ended December 31, 2002 from $100.0 million for the comparable prior year period. This increase is primarily the
result of operational changes implemented during the year ended December 31, 2002 to ensure compliance with personnel licensing and other regulatory requirements, and to allow for rapid
resolution of these regulatory concerns. As a result, certain cost increases were temporary increases needed for rapid resolution, while other operational changes will have ongoing cost increases.

The
most significant temporary cost increase was for outsourced testing. In April 2002, we suspended more than one thousand tests to ensure full and immediate compliance with
personnel licensing requirements for our laboratory. The orders we continued to receive for the suspended tests were forwarded to other laboratories for processing. This operational change resulted in
an increase of costs for outsourced testing, adding more than $6.0 million to cost of services in 2002 as compared to the prior year period. With the successful hiring, training, and
certification of additional California licensed personnel during third quarter 2002, we reinstated nearly 900 tests as of October 31, 2002.

49

---

This reinstatement of tests resulted in a significant decline in outsourcing costs for the fourth quarter 2002, and we believe will result in a decline of outsourcing costs in 2003 of more than
$4.5 million. In addition, we incurred cost increases in 2002 associated with the hiring, training, and certification of licensed laboratory personnel, adding approximately $1.0 million
to total cost of services. While we believe these costs were temporary, and do not expect to incur this level of expenditures in 2003, this reduction is dependent on our successful retention of these
new personnel, and no significant turnover in our laboratory workforce in 2003. Also, approximately $350,000 of one-time costs were incurred in cost of services associated with the
subleasing of our Memphis facility for the period July 1, 2002 through September 14, 2007.

As
part of ongoing changes made to ensure compliance with California requirements for licensed personnel, we now only use California-licensed clinical laboratory scientists to perform
the analytical portions of clinical testing. This change adds approximately $350,000 per quarter of incremental ongoing costs. For the period ended December 31, 2002, additional costs of
approximately $1.0 million were incurred for this change in personnel as compared to the year 2001. These increases are partially offset by lower reagent, distribution and royalty costs due to
lower accession volumes. As a percentage of revenue, cost of services increased to 74.5% for the year ended December 31, 2002 from 57.1% from the comparable prior year period.

Selling, General and Administrative Expenses (Exclusive of Stock-Based Compensation Charges)

Selling, general and administrative expenses (S,G&A) decreased approximately $4.4 million, or 7.8%, to $51.2 million for the year ended
December 31, 2002 from $55.6 million for the prior year period. This decrease is due primarily to a reduction in salary and benefit costs of approximately $2.2 million as a result
of our restructuring and reduction in force announced in June 2002 and an approximate $1.7 million reduction in certain sales and marketing costs, such as commissions and bonuses, that
declined commensurate with our lower revenues. In addition, approximately $1.4 million of S,G&A costs were incurred during the year ended December 31, 2001 for the acquisition and
operation of BBI Clinical Laboratories facility in Connecticut, in which we ceased operations in 2001. As a percentage of revenue, selling, general and administrative expenses increased to 36.6% for
year 2002 as compared to 31.7% for the comparable prior year period. We expect S,G&A costs will decline further in 2003 due to the ongoing benefits of our restructuring efforts and anticipated lower
revenues, resulting in a decrease of approximately $4 million as compared to the full year 2002. This decrease assumes no significant increases in certain costs such as insurance and taxes, and
that we do not have a significant increase in revenues.

Stock-Based Compensation Charges

Stock-based compensation charges decreased from approximately $1.1 million for the period ended December 31, 2001 to a net credit of approximately
$28,000 for the period ended December 31, 2002. This decrease was primarily due to forfeited stock options resulting from the June and November 2002 reductions in workforce that had the
effect of reducing future amortization.

Restructuring Charge

On June 18, 2002, we announced a reduction in workforce totaling 10% as part of an overall restructuring plan. In connection with the restructuring effort,
we recorded a charge of approximately $3.6 million in the second quarter of 2002. The charge comprised severance payments and related obligations for employees whose positions were eliminated.

During
September 2002, as a result of further business review and the refinement of our core strategic business, we eliminated some employee positions primarily in the area of our
clinical trials department. We recorded a restructuring charge of approximately $468,000 in the third quarter of 2002.

50

---

The charge comprised $199,000 of severance payments for employees whose positions were eliminated and a $269,000 write-off of certain assets related to our clinical trials business.

In
November 2002, in our continuing efforts to manage costs and align our business with current business levels, we had a reduction in workforce focused primarily on the
laboratory. We recorded a restructuring charge of approximately $984,000 in the fourth quarter of 2002. Approximately $508,000 of severance payments for employees whose positions were eliminated was
recorded as a charge. In addition, during the fourth quarter 2002, we recorded a charge of $476,000 for the write-off of certain capitalized costs associated with the delayed move to our
new Valencia facility, and the related termination of the synthetic lease financing arrangement with the banking group led by BNP Paribas.

Approximately
$2.1 million of severance and related obligations have been paid as of December 31, 2002. The remaining severance costs of approximately $2.2 million
will be paid during 2003 and 2004.

Charge Related to Regulatory Matters

In April 2002, we received a letter from CMS imposing certain sanctions as a result of laboratory inspections conducted by CDHS in June and
October 2001. The sanctions included cancellation of Medicare and Medicaid payments for services performed by the Company on and after February 22, 2002 and a civil money penalty of
$3,000 per day for each day during the sanction period beginning on February 22, 2002. On July 17, 2002 we were informed by CMS that it had deemed Specialty to be in compliance with all
condition level requirements of CLIA as of June 19, 2002 and that Specialty's ability to bill Medicare and Medicaid for its testing services had been reinstated as of June 19, 2002. In
addition, the July 17 letter from CMS notified us of a civil money penalty of $3,000 per day for each day during the sanction period from February 22, 2002 through June 19, 2002.
In order to facilitate an immediate resolution with CMS, we elected to withdraw our appeal of the sanctions we filed with CMS on April 17, 2002, and we will not seek reimbursement for services
performed for beneficiaries of Medicare and Medicaid during the sanction period of February 22, 2002 through June 19, 2002. However, because CMS imposed its sanctions retroactively to
February 22, 2002, we billed Medicare and Medicaid programs for some services before we were notified of the actual imposition of the sanctions by CMS on April 12, 2002. We have sought
guidance from CMS as to how the period of retroactive sanctions should be treated, and we have set aside and reserved those Medicare or Medicaid payments from the period of February 22, 2002
through April 12, 2002 until we receive additional guidance from CMS. We did not challenge CMS' imposition of a monetary fine of $351,000, representing $3,000 per day during the sanction
period. We have recorded a charge relating to these actions of approximately $2.3 million for the period ending December 31, 2002. A charge of $1.9 million is comprised of
$1.1 million to reserve for Medicare and Medicaid services earned and billed for the period of February 22, 2002 to March 31, 2002 with the remaining balance for regulatory fines,
inspection costs, and incremental legal expenses related to the CDHS and CMS regulatory actions. In pursuing patient collections, information was subsequently provided by the patient or our client
that the services provided were covered by Medicare or Medicaid during the period of February 22 through June 19, 2002, resulting in us writing off these receivables. These
write-offs along with additional reserves, totaled $400,000, and were recorded as a charge during fourth quarter of 2002.

Interest (Income) Expense, Net

Net interest income decreased to approximately $1.5 million for the year ended December 31, 2002 as compared to net interest income of approximately
$3.5 million for the year ended December 31, 2001. The decrease is primarily due to the significant interest rate declines that occurred during 2001, resulting in lower interest yields
on our investments coupled with cash utilized to finance our new facility construction and upgrade our information technology infrastructure.

51

---

Provision for Income Taxes (Benefits)

Provision for income taxes (benefits) was a benefit of approximately $7.9 million for the year ended December 31, 2002 as compared to
$8.9 million in expense for the year ended December 31, 2001. Our effective tax rate for the full year of 2002 was 37.2% as compared to 40.4% for the prior year period. The decline in
the effective tax rate is a result of certain non-deductible costs, such as penalties, incurred in 2002 and the limitation of loss deductions in the state of California.

Net Income (Loss)

A net loss of $13.4 million was recorded for the year ended December 31, 2002 compared to net income of $13.1 million for the comparable
prior year period, a decrease of approximately $26.5 million. The decrease is primarily due to significant one-time charges including severance costs and related costs due to
restructurings and reductions in workforce totaling approximately $5.1 million; charges related to the CMS actions of nearly $2.3 million; and lost revenues from Medicare and Medicaid of
approximately $2.3 million. In addition, these results reflect the impact of increased outsourced testing costs totaling approximately $6.0 million for 2002 as compared to the prior year
period. This decrease in 2002 is also related to our year-over-year reduction of nearly 13% in our aggregate average selling price due to our client mix-shift
toward hospital-based business and the reduction in independent laboratory business. As a percentage of net revenue, a net loss of 9.6% was recorded for the year ended December 31, 2002 as
compared to net income of 7.5% for the comparable prior year period.

EBITDA

EBITDA reflected a loss of $15.8 million for the year ended December 31, 2002 as compared to earnings of $25.5 million for the comparable
prior year period. As a percentage of net revenue, EBITDA decreased to a loss of 11.3% for the year ended December 31, 2002 from earnings of 14.5% for the comparable prior year period. The
decrease is primarily due to significant one-time charges including
severance costs and related costs due to restructurings and reductions in workforce totaling approximately $5.1 million; charges related to the CMS actions of nearly $2.3 million; and
lost revenues from Medicare and Medicaid of approximately $2.3 million. In addition, these results reflect the impact of increased outsourced testing costs totaling approximately
$6.0 million for 2002 as compared to the prior year period. This decrease is also related to our year-over-year reduction of nearly 13% in our aggregate average selling
price due to our client mix-shift toward hospital-based business and the reduction in independent laboratory business.

Year Ended December 31, 2001 Compared with Year Ended December 31, 2000

Net Revenue

Net revenue increased approximately $22.0 million, or 14.3%, to $175.2 million for the year ended December 31, 2001 from
$153.2 million for the year ended December 31, 2000. Revenue grew as a direct result of increased accession volumes, which increased nearly 19% to more than 3.1 million assays for
the year 2001 as compared to 2.6 million assays for the year 2000, offset partially by a decline in average selling prices. This accession growth came primarily from our existing business,
increasing approximately 17% during the year as compared to the comparable prior year period. The accession volumes resulting from the acquisition of BBI Clinical Laboratories on February 20,
2001 accounted for nearly two percentage points of growth. Average selling prices for the year of 2001 declined approximately 4% as compared to the prior year of 2000. This reduction in average
selling prices is reflective of test mix changes resulting from our growing hospital customer base, pricing reductions in contract renewals, and the impact on test mix in September and
October 2001 due to the events of September 11. Revenues from our hospital clients grew to approximately 56% of total net

52

---

revenues for the year ended December 31, 2001 as compared to approximately 51% for the year ended December 31, 2000 as a direct result of our continued sales focus towards hospital
customers.

Cost of Services

Cost of services, which includes costs for laboratory operations, distribution services, and research and development, increased approximately
$13.1 million, or 15.1%, to $100.0 million for the year ended December 31, 2001 from $86.9 million for the comparable prior year period. This increase is directly
attributed to the increase in assay volume and the costs associated with the acquisition of the clinical operations of BBI Clinical Laboratories in first quarter 2001. During the year, we maintained
redundant operations as we transitioned the clinical operations of BBI Clinical Laboratories to our Santa Monica facilities. The transition of laboratory operations was completed during the third
quarter of 2001. As a percentage of net revenue, cost of services increased to 57.1% for the year ended December 31, 2001 from 56.7% for the comparable prior year period. This decline is
reflective of the
additional costs associated with the BBI Clinical Laboratories acquisition offset partially by the improved efficiencies provided by the ongoing automation of our laboratory operations and the
economies of scale realized by processing significantly higher assay volume.

Selling, General and Administrative Expenses (Exclusive of Stock-Based Compensation Charges)

Selling, general and administrative expenses (S,G&A) increased approximately $6.3 million, or 12.9%, to $55.6 million for the year ended
December 31, 2001 from $49.3 million for the prior year period. Selling, marketing and related expenses accounted for approximately $2.7 million of this growth in S,G&A resulting
from increased revenues and servicing a larger customer base. The acquisition of BBI Clinical Laboratories added more than $1.6 million to S,G&A, which includes approximately $400,000 of
certain charges associated with the acquisition and approximately $392,000 recorded for amortization of intangible assets during the year of 2001. Approximately $1.5 million was due to
increasing our corporate infrastructure to support our business growth and to meet the requirements of being a public company. Expansion of our customer related offerings of
DataPassportMD® and the beta testing of our Outreach Express® contributed nearly $1.0 million of incremental S,G&A. As a percentage of revenue, selling, general and
administrative expenses decreased to 31.7% for year 2001 as compared to 32.2% for the comparable prior year period.

Stock-Based Compensation Charges

Stock-based compensation charges were $1.1 million for both the years ended December 31, 2001 and 2000. These charges are related to the
amortization of deferred stock compensation.

Write-Down of Unused Facilities

A property lease between the Company and a partnership in which the Company's Chairman of the Board and Chief Executive Officer, Dr. James B. Peter, was
both a direct and indirect owner was terminated on September 1, 2000 on which date the Company had a balance of approximately $369,000 in unamortized leasehold improvements for this property. A
loss for this amount was recognized on September 1, 2000. No additional losses were recorded during 2001.

Interest (Income) Expense, Net

Net interest income increased to approximately $3.5 million for the year ended December 31, 2001 as compared to net interest expense of
approximately $940,000 for the year ended December 31, 2000. The increase in interest income is the result of investments being made with the proceeds from our initial public offering held in
December 2000 as funds have been invested in money market, short-term and
long-term investments. The decrease in interest expense is due to the reduction of debt in December 2000 paid by proceeds from our initial public offering.

Provision for Income Taxes

Provision for income taxes was $8.9 million for the year ended December 31, 2001 as compared to $6.1 million for the comparable prior year
period. Our effective income tax rate declined slightly to 40.4% for the year ended December 31, 2001 from 41.1% for the year ended December 31, 2000. The effective tax rate decline is a
result of tax planning reviews and initiatives.

Net Income

Net income increased by $4.4 million, or 50.8%, to approximately $13.1 million for the year ended December 31, 2001 from approximately
$8.7 million for the comparable prior year period. The increase is due primarily to an increase in operating income resulting from higher assay volume, efficiencies provided by ongoing
automation of assays, and interest income recognized on the investment of funds from our initial public offering. As a percentage of net revenue, net income increased to 7.5% for the year ended
December 31, 2001 as compared to 5.7% for the comparable prior year period.

EBITDA

EBITDA increased by approximately $3.9 million, or 18.1%, to $25.5 million for the year ended December 31, 2001 from $21.6 million for
the comparable prior year period. As a percentage of net revenue, EBITDA increased to 14.5% for the year ended December 31, 2001 from 14.1% for the comparable prior year period. These results
reflect the efficiencies provided by ongoing automation of assays, economies of scale associated with processing significantly higher assay volume partially offset by us maintaining redundant
operations as we transitioned the clinical operations of BBI Clinical Laboratories to our Santa Monica facilities.

Liquidity and Capital Resources

Operating activities for the year ended December 31, 2002 used net cash of $1.4 million as we incurred a net loss from operations of
$13.4 million offset by $7.0 million of depreciation and amortization,
$2.6 million of tax benefits generated from the exercise of employee stock options, and $11.2 million of cash provided by accounts receivable collections. In addition, cash was used as a
result of an increase in our tax benefits, as reflected in income taxes refundable of $8.5 million. This compares to net cash provided by operating activities of $19.5 million for the
year ended December 31, 2001. For 2001, $13.1 million of cash was provided by income from operations, increased by $7.0 million of depreciation and amortization, $3.9 million of
tax benefits generated from the exercise of employee stock options, and $4.4 million increase in deferred income taxes. This was offset, in part, by $8.8 million of reductions in
accounts payable, income taxes payable and other current liabilities.

Investing
activities for the year ended December 31, 2002 provided net cash of $6.8 million as we repositioned approximately $41.6 million of short-term
and long-term investments to cash and cash equivalents, offset by approximately $34.7 million increase in capital expenditures. This represents a $21.0 million increase in
capital expenditures from the comparable prior year period. This increase is primarily due to the $25.3 million for construction of the new Valencia facility which we financed by using
$20.7 million of cash and investments, and $4.6 million of funds borrowed from BNP Paribas which were repaid in fourth quarter of 2002. Of the remaining capital expenditures,
approximately $4.1 million was expended for the upgrade of our information technology infrastructure and the move of our data center to a third party location which will be completed during the
first half of 2003. This compares to a cash use of $82.5 million for the year ended December 31, 2001, as we repositioned approximately $59.6 million of cash to
short-term and long-term investments, paid $9.1 million in cash for the acquisition of BBI Clinical Laboratories, paid $8.7 million to acquire land in Valencia,
California for our new facility, and spent $5.1 million for capital expenditures to expand our information technology platform and laboratory automation and equipment.

54

---

Net
cash provided by financing activities was $1.8 million for the year ended December 31, 2002 as compared to $2.6 million for the prior year period. Cash provided
in the year of 2002 was primarily from the receipt of funds from the purchase of common stock by employees through our Employee Stock Purchase Plan and the exercise of stock options. In addition, we
borrowed $4.6 million of funds from the bank group led by BNP Paribas for our new facility construction. We decided to go on balance sheet with the Valencia facility lease transaction and we
exercised our purchase option under the agreement. During fourth quarter of 2002, we paid off the bank loan so we could obtain title to the ground lease and facility improvements, and thus ended the
synthetic lease financing arrangement. The building is recorded in property and equipment on our balance sheet.

In
March 2002, we also obtained a bank loan agreement that provided for a revolving line of credit up to $40 million. The banking group led by BNP Paribas also provided
this loan agreement. We had no borrowings under this bank loan agreement and terminated this loan agreement in fourth quarter of 2002. We expect to complete a new, reduced financing arrangement within
the next three months and expect the new agreement will provide the right to borrow up to $10 million for the Valencia facility.

With
the resolution of sanctions imposed by CMS and CDHS, our focus is on rebuilding client confidence and stabilizing our business. To minimize any disruptions in service to our
customers based
on planning and executing a move to a new facility during the rebuilding period, in October 2002, we announced that we would postpone the move to our new facility in Valencia until the first
half of 2004. Accordingly, the construction of the new facility will be delayed. We have halted construction at completion of the Core and Shell of the facility, a logical break point, and this phase
was substantially completed in January 2003 with the remaining work of this phase concluding during February and March 2003. We estimate incurring approximately $5 million of
additional capital expenditures in the first quarter of 2003 for these purposes. During the construction postponement period, we expect to see an increase in operating costs to provide security,
insurance, maintenance, and fund taxes, amounting to approximately $400,000 per quarter. The decision to restart the building project will occur sometime in the second half of 2003. If we decide to
restart the facility construction, we will look to a more traditional construction and mortgage financing arrangement to complete the project.

Our
cash and cash equivalents combined with short-term and long-term investments totaled approximately $40.9 million on December 31, 2002 as
compared to $75.1 million on December 31, 2001. This reduction in cash is a direct result of increased capital expenditures, primarily for the Valencia facility and information
technology investments that are related to our infrastructure upgrade and the move of our data center to a third party location. Our investments, accounting for $18.5 million, are primarily in
commercial paper and corporate bonds. We expect existing cash and cash equivalents, short-term investments and our new financing arrangement will be sufficient to fund our operations, meet
our capital requirements to support our growth and allow strategic technology licensing for the next year.

However,
it is possible that we may need or elect to raise additional funds to fund our activities beyond the next year or to consummate acquisitions of other businesses, assets or
technologies. We could raise such funds by selling more stock to the public or to selected investors, or by borrowing money. In addition, even though we may not need additional funds, we may still
elect to sell additional equity securities or obtain credit facilities for other reasons. We cannot assure you that we will be able to obtain additional funds on commercially favorable terms, or at
all. If we raise additional funds by issuing additional equity or convertible debt securities, the ownership percentages of existing shareholders would be reduced. In addition, the equity or debt
securities that we issue may have rights preferences or privileges senior to those of the holders of our common stock.

Although
we believe we have sufficient capital to fund our activities for at least the next twelve months, our future capital requirements may vary materially from those now planned.

Inflation

Inflation was not a material factor in either revenue or operating expenses during the past three fiscal years ended December 31, 2000, 2001, and 2002.

Subsequent Events

In January 2003, Thomas E. England, Ph.D. began a transition from the position of Vice President, Laboratory Operations. Effective April 1, 2003,
Mr. England's title will be Director, Research & Development and General Manager, Clinical Trials. Mr. England will oversee those two areas of our business.

Recent Accounting Pronouncements

In May 2002, SFAS No. 145,Recession of FASB Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13
and Technical Corrections as of April 2002was issued. As a result of the rescission of SFAS No. 4, gains and losses related to the extinguishments of debt should
be classified as extraordinary only if they meet the criteria outlined under APB Opinion No. 30,Reporting the Results of OperationsReporting the Effects of
Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions. SFAS No. 64,Extinguishments
of Debt Made to Satisfy Sinking-Fund Requirements, was an amendment to SFAS No. 4 and is no longer necessary. SFAS No. 44, Accounting for Intangible Assets of Motor Carriers, defined accounting requirements for the effects of the transition to the Motor Carrier Act of 1980.
The transitions are complete and SFAS No. 44 is no longer necessary. SFAS No. 145 amends SFAS No. 13,Accounting for Leases,
requiring that any capital lease that is modified resulting in an operating lease should be accounted for under the sale-leaseback provisions of SFAS No. 98, Accounting for Leasesor SFAS
No. 28,Accounting for Sales with Leasebacks, as applicable. SFAS
No. 145 is effective for fiscal years beginning after May 15, 2002. The adoption of the provisions of SFAS No. 145 is not expected to have a material impact on the Company's
results of operations, financial position or cash flows.

In
June 2002, SFAS No. 146,Accounting for Costs Associated with Exit or Disposal Activities, which requires that a
liability for a cost associated with an exit or disposal activity be recognized when the liability is incurred, was issued. This statement nullifies Emerging Issues Task Force Issue
No. 94-3,Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a
Restructuring), which required that a liability for an exit cost be recognized upon the entity's commitment to an exit plan. SFAS No. 146 is effective for exit or
disposal activities that are initiated after December 31, 2002. The adoption of the provisions of SFAS No. 146 is not expected to have a material impact on the Company's results of
operations, financial position or cash flows.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

At any time, fluctuations in interest rates could effect interest earnings on our cash and cash equivalents and interest expense on our existing line of credit.
We believe that the effect, if any, of reasonably possible near term changes in interest rates on our financial position, results of operations,
and cash flows would not be material. Currently, we do not hedge these interest rate exposures. The primary objective of our investment activities is to preserve capital. We have not used derivative
financial instruments in our investment portfolio.

At
December 31, 2002, our holdings, which had an original maturity date of less than 90 days, were classified as cash and cash equivalents on our consolidated balance
sheet. At December 31, 2002, we had cash and cash equivalents of $22.4 million, which had a weighted average yield of 1.58% per annum. At December 31, 2002, our
long-term investment balance of $18.5 million consisted of corporate bonds and government securities with maturity dates beyond one year had a weighted average yield per annum of
3.84% and an average of 13.5 months until maturity.

that our audits provide a reasonable basis for our opinion.

In

Specialty Laboratories, Inc.
Notes to Consolidated Financial Statements

December 31, 2002

1. Summary of Significant Accounting Policies

Description of Business

Specialty Laboratories, Inc. (the Company) is a corporation that provides specialized laboratory-testing services to physicians, hospitals, and independent
laboratories throughout the United States. The Company's continuing operations are in one reportable segment, the domestic medical laboratory industry.

Principles of Consolidation and Basis of Presentation

The consolidated financial statements include the accounts of Specialty Laboratories, Inc. and its subsidiary, BVI Specialty Laboratories
International, Ltd. (SLIL) (100% owned). All intercompany transactions have been eliminated in consolidation.

Common Stock Split

On October 30, 2000, the Company's Board of Directors amended the Company's Articles of Incorporation to effect a 2.2 for 1 stock split and to increase the
authorized number of shares of
common stock to 100,000,000. All per share and common share amounts presented in these consolidated financial statements for 2000 have been adjusted to reflect the stock split.

Cash and Cash Equivalents

The Company considers highly liquid debt securities with original maturities of 90 days or less to be cash equivalents.

Investments

All investments (which include U.S. government and corporate debt securities) are designated as available-for-sale. Accordingly,
investments are carried at fair value and unrealized gains and losses, net of applicable income taxes, are recorded in shareholders' equity. Investments are classified as short-term or
long-term based on their contractual maturity dates.

Accounts Receivable and Net Revenue

Accounts receivable and net revenue are recorded net of contractual allowances. The allowance for doubtful accounts represents an estimate of future credit
losses.

Inventory

Inventory consists primarily of laboratory supplies and is stated at the lower of the average cost or market.

Property and Equipment

Property and equipment are stated at cost. Depreciation and amortization are computed using the straight-line method over the estimated useful lives
of the respective assets as follows:

Professional equipment

510 yearsOffice furniture and equipment

510 yearsAutomotive equipment

35 yearsComputer equipment

35 yearsSoftware

3 yearsLeasehold improvements

The lesser of life of asset or lease term


Goodwill and Intangible Assets

The Company allocates the excess of the purchase price over the fair value of the net assets acquired to goodwill and identifiable intangible assets. Identifiable
intangible assets include customer lists and license agreement fees. The Company amortizes customer lists and license agreement fees evenly over periods of 10 and 4.5 years, respectively. Prior
to 2002, the Company amortized goodwill over 20 years. Accumulated amortization totaled $400,000 and $689,000 at December 31, 2001 and 2002, respectively.

In
July 2001, the Financial Accounting Standards Board issued Statements of Financial Accounting Standards (SFAS) No. 141, "Business Combinations", and No. 142,
"Goodwill and Other Intangible Assets", effective for fiscal years beginning after December 15, 2001. Under the new rules, goodwill is no longer amortized, but is subject to annual impairment
tests. The tests for measuring goodwill impairment under SFAS No. 142 are more stringent than previous tests required by SFAS No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed of". Under SFAS No. 121, we applied an undiscounted cash flow model to assess the fair value of our Company,
which did not result in the recognition of goodwill impairment.

Under
the guidance of SFAS No. 142, we concluded that there was no impairment of goodwill for the year ended December 31, 2002 since our fair value exceeded the book equity
value. The following table reflects consolidated results adjusted as though the adoption of the SFAS No. 142

next three years and $197,000 for the subsequent five years.

Long-lived Asset Impairment

The Company reviews long-lived assets for impairment when events or changes in business conditions indicate that their carrying value may not be
recovered. The Company considers assets to be impaired and writes them down to fair value if expected associated cash flows are less than the carrying amounts. Fair value is the present value of the
associated cash flows. The Company has determined that no long-lived assets are impaired at December 31, 2002.

Revenue Recognition

The Company recognizes revenue as services are rendered upon completion of the testing process for a specific customer order for which the Company has no future
performance obligations to the customer, the customer is obligated to pay and the fees are non-refundable. This generally occurs when the assay
result is reported to the customer. The Company's revenue recognition policies are in compliance with Securities and Exchange Commission Staff Accounting Bulletin No. 101.

Services
are provided to certain patients covered by various third-party payor programs including Medicare and Medicaid. Billings for services under third-party payor programs are
included in net revenue net of allowances for differences between the amounts billed and estimated receipts under such programs. Adjustments to the estimated payment amounts based on final settlement
with the third-party payor programs are recorded upon settlement. In 2000, 2001, and 2002, 5.5%, 4.6%, and 4.8%, respectively, of net revenue was paid by Medicare or Medicaid programs.

Research and Development Expenditures

Research and development expenditures are expensed as incurred. The amounts charged to research and development expense were $2,094,000, $2,266,000, and
$2,215,000 in 2000, 2001, and 2002, respectively.

Concentrations of Credit Risk

The Company's concentration of credit risk with respect to accounts receivable is limited due to the large number of payors comprising its customer base which are
spread across the United States. In addition, the Company maintains allowances for potential credit losses and such losses have been within management's expectations. The Company routinely assesses
the financial strength of its customers and generally does not require collateral.

Unilab
Corporation accounted for approximately 10% of our net revenue in 2002. In 2001 and 2000, no customer accounted for over 10% of net revenue.

Estimates and Assumptions

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses. The Company routinely
estimates amounts to be recovered from third-party payors. Actual results could differ from those estimates.

Stock-Based Compensation

The Company accounts for stock options under the recognition and measurement principles (the intrinsic-value method) prescribed in Accounting Principles Board
(APB) Opinion No. 25,Accounting for Stock Issued to Employees, and related interpretations. Compensation cost for stock options is reflected in
net income and is measured as the excess of the market price of the Company's stock at the date of grant over the amount an employee must pay to acquire the stock. SFAS, No. 123, Accounting for Stock-based
Compensation, established accounting and disclosure requirements using a fair-value based method of accounting
for stock-based employee compensation plans.

In
December 2002, SFAS No. 148, Accounting for Stock-Based CompensationTransition and Disclosure was issued. SFAS No. 148 amends SFAS No. 123 to
provide alternative methods of transition to SFAS No. 123's fair value method of accounting for stock-based employee compensation. It also amends and expands the disclosure provisions of SFAS
No. 123 and APB Opinion No. 28, Interim Financial Reporting, to require disclosure in the summary of significant accounting policies of the effects of an entity's accounting policy with
respect to stock-based employee compensation on reported net income and earnings per share in annual and interim financial statements. While SFAS No. 148 does not require companies to account
for employee stock options using the fair-value method, the disclosure provisions of SFAS No. 148 are applicable to all companies with stock-based employee compensation, regardless
of whether they account for that compensation using the fair-value method of SFAS No. 123 or the intrinsic-value method of APB Opinion No. 25. The Company has adopted the
disclosure requirements of SFAS No. 148.

Pro
forma net income, as required to be disclosed by SFAS No. 148, determined as if the Company had accounted for its employee stock options under the fair-value
method of that Statement, is as follows:

pro forma amounts may not be representative in future disclosures since the estimated fair value of stock options would be amortized to expense over the vesting period, and
additional options may be granted in future years.

The
fair value for these options was estimated at the date of grant using the Black-Scholes option pricing model with the following assumptions:

.71


For
sales of the Company's common stock to employees at a price below such estimated fair value, the difference between the sales price and such estimated fair value was charged to
expense as of the date of the sales.

All
outstanding stock options granted by the Company prior to 1999 were canceled in 1999 and were concurrently replaced with newly granted stock options. The exercise price for certain
of the newly granted options was lower than the exercise price of the canceled options. These "repriced" options were accounted for as "variable" options effective July 1, 2000 until their
exercise in September 2000 in accordance with FASB Interpretation No. 44.

Income Taxes

The Company utilizes the liability method of accounting for income taxes as set forth in Statement of Financial Accounting Standards No. 109, "Accounting
for Income Taxes." Under this method, deferred income taxes are determined based on the difference between the financial statement and tax basis of assets and liabilities using current tax rates and
regulations.

Fair Value of Financial Instruments

The Company's financial instruments consist mainly of cash, cash equivalents, short-term investments, long-term investments, accounts
receivable, accounts payable and its bank credit facility. The fair value of substantially all financial instruments of the Company approximates their carrying values in the aggregate due to the
short-term nature of these instruments. The interest rates on borrowings under the Company's bank credit facilities are adjusted periodically to market rates.

The
Company has not used any derivatives or other foreign currency hedging instruments and, accordingly, believes that Statement of Financial Accounting Standards No. 133,
"Accounting for Derivative Instruments and Hedging Activities," has had no effect on the Company's financial statements.

Earnings Per Share

Basic earnings (loss) per share are computed by dividing net income (loss) by the weighted average number of common shares outstanding. Dilutive earnings per
share are computed by dividing net income by the weighted average number of common shares outstanding plus potentially dilutive shares for the portion of the year they were outstanding. Potentially
dilutive common shares result solely from outstanding stock options. Since the Company reported a net loss in 2002, these potentially dilutive

F-11

common shares were excluded from the diluted loss per share calculation because they were anti-dilutive.

Basic
and diluted earnings (loss) per share information was calculated based on the following weighted average shares:

Recent Accounting Pronouncements

In May 2002, SFAS No. 145,Recession of FASB Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13
and Technical Corrections as of April 2002was issued. As a result of the rescission of SFAS No. 4, gains and losses related to the extinguishments of debt should
be classified as extraordinary only if they meet the criteria outlined under APB Opinion No. 30,Reporting the Results of OperationsReporting the Effects of
Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions. SFAS No. 64,Extinguishments
of Debt Made to Satisfy Sinking-Fund Requirements, was an amendment to SFAS No. 4 and is no longer necessary. SFAS No. 44, Accounting for Intangible Assets of Motor Carriers, defined accounting requirements for the effects of the transition to the Motor Carrier Act of 1980.
The transitions are complete and SFAS No. 44 is no longer necessary. SFAS No. 145 amends SFAS No. 13,Accounting for Leases,
requiring that any capital lease that is modified resulting in an operating lease should be accounted for under the sale-leaseback provisions of SFAS No. 98, Accounting for Leasesor SFAS
No. 28,Accounting for Sales with Leasebacks, as applicable. SFAS
No. 145 is effective for fiscal years beginning after May 15, 2002. The adoption of the provisions of SFAS No. 145 is not expected to have a material impact on the Company's
results of operations, financial position or cash flows.

In
June 2002, SFAS No. 146,Accounting for Costs Associated with Exit or Disposal Activities, which requires that a
liability for a cost associated with an exit or disposal activity be recognized when the liability is incurred, was issued. This statement nullifies Emerging Issues Task Force Issue
No. 94-3,Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a
Restructuring), which required that a liability for an exit cost be recognized upon the entity's commitment to an exit plan. SFAS No. 146 is effective for exit or
disposal activities that are initiated after December 31, 2002. The adoption of the provisions of SFAS No. 146 is not expected to have a material impact on the Company's results of
operations, financial position or cash flows.

2. Acquisitions

On February 20, 2001, the Company acquired certain assets and liabilities of BBI Clinical Laboratories, Inc. (BBICL), a Massachusetts corporation,
for $9,500,000 in cash. The purchase price was allocated to the assets acquired and liabilities assumed based on the estimated fair values as of the purchase closing date. The acquisition agreement
provided for a reduction of the purchase price if certain performance measurements (i.e., asset delivery, client retention and accounts receivable collections) were not achieved. A subsequent
evaluation of these performance measurements resulted in the return of $358,000 by BBICL to the Company in December 2001. Of the $9,142,000 net purchase price, approximately $5,882,000 was
allocated to goodwill and $1,932,000 was allocated to the customer list. The acquisition has been accounted for under the purchase method of accounting. The operating results of BBICL are included in
the financial statements from the acquisition date.

The
following unaudited pro forma information below presents the consolidated results of operations as if the BBICL acquisition occurred on January 1, 2001. Such unaudited pro

3. Charge Related to Regulatory Matters

By letter dated April 12, 2002, the federal Centers for Medicare & Medicaid Services (CMS) notified the Company of its conclusions regarding
laboratory inspections in June and October 2001 conducted by the California Department of Health Services (CDHS). CMS concluded that the Company's February 2002 response to deficiencies
detected in the inspections did not constitute a credible allegation of compliance. As a result, CMS imposed certain sanctions, including notice of revocation of the Company's Clinical Laboratory
Improvement Act (CLIA) certificate, canceling the Company's approval to receive Medicare and Medicaid payments for services performed, imposing a civil money penalty of $3,000 per day for each day
during the sanction period, and imposing a directed plan of correction by which CMS could notify the Company's customers of the Company's non-compliance and the nature and effective date
of any sanctions imposed. The Company filed an appeal to the CMS action on April 17, 2002, and the appeal stayed the revocation of the Company's CLIA certificate during the Company's
administrative appeal. The cancellation of Medicare and Medicaid payments was effective for services performed by the Company on and after February 22, 2002.

We
filed supplemental documentation supporting our compliance with the applicable requirements with CDHS and CMS on April 26, 2002. In addition, on April 26, 2002, we
requested that CDHS rescind its proposed sanctions outlined in the March 28, 2002 letter based on our supplemental submission. In May and June 2002, CDHS conducted additional unannounced
inspections, and we provided additional documentation supporting our compliance with CDHS requirements. By letter

F-13

---

dated June 28, 2002, and amended on July 18, 2002, CDHS indicated that we were in substantial compliance with California clinical laboratory law. CDHS also imposed sanctions of a civil
money penalty of $1,000 per day for 344 days (i.e., $344,000), plus $20,430 for the cost of conducting their investigations, and imposed onsite monitoring for three years, including unannounced
inspections. We did not appeal these imposed sanctions.

On
July 17, 2002, CMS notified the Company that it had deemed Specialty in compliance with all condition level requirements of CLIA and, that Specialty's ability to bill Medicare
and Medicaid for its testing services has been reinstated, effective June 19, 2002, and that all actions against the Company's CLIA certificate have been rescinded. In order to facilitate an
immediate resolution with CMS, the Company elected to withdraw the appeal of the sanctions the Company filed with CMS on April 17, 2002, and the Company will not seek reimbursement for services
performed for beneficiaries of Medicare and Medicaid during the sanction period of February 22, 2002 through June 19, 2002. However, because CMS had imposed its sanctions retroactively
to February 22, 2002, the Company had billed Medicare and Medicaid programs for some services before the notification of the actual imposition of the sanctions by CMS was received on
April 12, 2002. The Company has sought guidance from CMS as to how the period of retroactive sanctions should be treated, and has set aside and reserved those Medicare or Medicaid payments from
the period of February 22, 2002 through April 12, 2002 until additional guidance is received from CMS. The Company did not challenge CMS' imposition of a monetary fine of $351,000,
representing $3,000 per day during the sanction period.

The
Company believes that the cancellation of the Company's approval to receive Medicare and Medicaid payments for services performed from February 22, 2002 through
June 19, 2002 should not affect testing for Medicare and Medicaid patients for whom the Company bills the hospital and other clients, but instead applies only to testing for which the Company
bills the Medicare and Medicaid programs directly. The Company recorded a charge in first quarter 2002 of approximately $1,241,000 to reserve for Medicare and Medicaid services earned and billed and a
civil money penalty, all pertaining to the period February 22, 2002 to March 31, 2002. During second quarter 2002, the Company did not recognize any net revenue related to Medicare and
Medicaid services and recorded a charge of approximately $612,000 for additional civil money penalties, costs for inspections, and incremental legal costs related to the CDHS and CMS regulatory
actions. Beginning July 1, 2002, with the resolution of sanctions imposed by CMS, the Company resumed the recognition of net revenue related to Medicare and Medicaid services performed. In
pursuing patient collections, subsequent information was provided by the patient or client that the services provided were covered by Medicare or Medicaid during the period of February 22
through June 19, 2002, resulting in the Company writing off these receivables. These write-offs along with additional reserves, totaled $400,000, and were recorded as a charge
during fourth quarter of 2002.

4. Restructuring Charge

On June 18, 2002, the Company announced a reduction in workforce totaling 10% as part of an overall restructuring plan. The plan involved all areas and
levels of the company. In connection with the restructuring effort, a charge of approximately $3,598,000 was recorded in the second quarter of 2002. The charge comprised severance payments and related
obligations for employees whose positions were eliminated.

F-14

---

During
September 2002, as a result of further business review and the refinement of our core strategic business the Company eliminated some employee positions primarily in the
area of the clinical trials department. A charge of approximately $468,000 was recorded in the third quarter of 2002. The charge comprised $199,000 of severance payments for employees whose positions
were eliminated and a $269,000 write-off of certain assets related to the clinical trials business.

In
November 2002, in the Company's continuing efforts to manage costs and align the business with current business levels, a reduction in workforce occurred focused primarily on
the laboratory. A restructuring charge of approximately $984,000 was recorded in the fourth quarter of 2002. Approximately $508,000 of the charge related to reductions in force, primarily laboratory
operations. In addition, approximately $476,000 of the charge was recorded for the write-off of certain capitalized costs associated with the delayed move to the new Valencia facility, and
the related termination of the synthetic lease financing arrangement with the banking group led by BNP Paribas.

7. Write-Down of Unused Facility Costs

In 1997, the Company leased a building in Memphis, Tennessee, for a potential geographical expansion of its operations. Subsequently, in June 1999, the
Company's management decided not to move into the Memphis facility and to sublease it to a third party. The accrual of estimated future lease costs was computed by calculating the present value of the
remaining lease payments, offset by the present value of the estimated future sublease income assuming a sublease start date of November 2002, using a discount rate of 7%. In June 2002,
the Company subleased the facility for the period July 1, 2002 through September 14, 2007, the end of the lease commitment. The liability balance as of December 31, 2002 was
$363,000. The Company does not anticipate any future adjustments to the accrual.

Beginning
in 1997, the Company leased on a month-to-month basis a property from a partnership in which the Company's former Chairman of the Board and Chief
Executive Officer is both a direct and indirect owner. The Company utilized a portion of the property and subleased the remainder. As a result of the Company's initial public offering, the lease
between the Company and the partnership was terminated on September 1, 2000 on which date the Company had a balance of $369,000 in unamortized leasehold improvements for this property.
Accordingly, a loss was recognized for this amount as of September 1, 2000.

9. Long-Term Debt

The Company had a bank loan agreement which provided for a revolving line of credit up to $30 million subject to a borrowing base limitation of 75% of
eligible accounts receivable. Borrowings were cross collateralized by substantially all of the Company's assets and contain certain restrictive covenants, including maintenance of certain levels of
financial ratios. Borrowings under this agreement bore interest at LIBOR plus a defined rate and were payable on September 30, 2003. The Company repaid the outstanding revolving line of credit
with proceeds from the initial public offering. There were no borrowings outstanding as of December 31, 2001. The revolving line of credit was terminated in March 2002.

In
March 2002, the Company entered into a 6.5 year lease agreement to finance the construction of our new laboratory and headquarters facility in Valencia, California. BNP
Paribas and a syndication of banks arranged our lease, which was initially structured as an off balance sheet financing arrangement, sometimes referred to as a "synthetic lease". Construction of the
new facility was to be completed in the second half of 2003, and the move from the existing location was scheduled shortly thereafter. Construction costs incurred through December 31, 2002 were
$25,327,000, of which we

F-17

---

financed $20,718,000 with investments and cash generated from operations and $4,609,000 was funded through borrowings from BNP Paribas.

The
Company decided to go on balance sheet with the Valencia facility lease transaction and notified the banking group led by BNP Paribas that we intended to exercise our purchase option
under the agreement. During fourth quarter of 2002, we paid off the $4,609,000 bank loan and ended the synthetic lease financing agreement.

In
March 2002, the Company also obtained a bank loan agreement that provided for a revolving line of credit up to $40,000,000. The bank group led by BNP Paribas also provided this
loan agreement. We had no borrowings under this bank loan agreement and terminated the loan agreement in fourth quarter of 2002.

There
were no amounts outstanding under the line of credit or term loans at December 31, 2001 and 2002.

expense for 2000, 2001 and 2002 was $1,243,000, $134,000 and $209,000, respectively.

10. Profit Sharing Plan401(k)

The Company maintains a defined contribution 401(k) profit sharing plan (the 401(k) Plan) covering all employees after minimum eligibility requirements have been
met. In accordance with the 401(k) Plan, eligible employees may contribute up to 15% of their salaries to the 401(k) Plan. The Company will match the employee's contribution at 50 cents per dollar up
to 6% of the employee's salary. Matching contributions by the Company to the 401(k) Plan amounted to $633,000, $686,000 and $735,000 in 2000, 2001 and 2002, respectively. Profit sharing contributions
to the 401(k) Plan are discretionary and no discretionary contributions were made during 2000, 2001 and 2002.

11. Deferred Compensation Program

The Company has a non-qualified deferred compensation program (the Program) for certain executives. Under the Program, employee-designated deferrals
of salary are withheld by the Company. An amount equal to the withholding is "invested" at the direction of the employee, in a portfolio of phantom investments selected from the available investments
under the Program, which are tracked by an administrator. With a portion of the withholding, the Company purchases life insurance policies on each of the participating executives with the Company
named as beneficiary of the policies.

Deferred
compensation, including gains and losses on phantom investments, amounted to $1,895,000 and $1,249,000 at December 31, 2001 and 2002, respectively, and is classified in
long-term liabilities. The cash surrender value of the life insurance policies, which amounted to $1,638,000 and $1,591,000 at December 31, 2001 and 2002, respectively, is recorded
in other assets.

12. Shareholders' Equity

Preferred Stock

During 2000, the Company's Board of Directors amended the Company's Articles of Incorporation to authorize 10,000,000 shares of no par value preferred stock. No
shares of preferred stock have been issued.

Ownership of Common Stock

On August 15, 2000, the Specialty Family Limited Partnership (Partnership) redeemed the Company's interest in the Partnership in exchange for 1,136,749
shares of the Company's common stock, which were then canceled by the Company.

Initial Public Offering

On December 8, 2000, the Company completed the initial public offering of 5,000,000 shares of its common stock at a price of $16.00 per share. The
underwriters subsequently exercised their overallotment option by purchasing an additional 750,000 shares of the Company's common stock at a price of $16.00 per share. After underwriters' discounts,
commissions and expenses, the net proceeds of the offering and overallotment exercise to the Company were $85,560,000. Other expenses of the offering aggregated $2,953,000.

Stock Option Plans

During 1999, the Company's Board of Directors approved the 1999 Stock Option/Stock Issuance Plan (the 1999 Plan) as a comprehensive equity incentive program and
granted 1,839,068 options to acquire shares of the Company common stock to certain employees and outside directors of the Company.
Outstanding stock options previously granted were effectively cancelled and replaced with new options under the 1999 plan. The options granted have an exercise price of $1.21 or $1.23 per share and
1,108,171 of such options were vested at their date of grant.

As
of January 1, 2000, the Company granted to certain employees of the Company 132,000 options to acquire shares of the Company's common stock at an exercise price of $1.56 per
share. As of July 1, 2000 the Company granted to certain employees 255,200 options to acquire shares of the Company's common stock at an exercise price of $7.00 per share.

On
September 5, 2000, the Company's Board of Directors adopted and the shareholders approved the 2000 Stock Incentive Plan (2000 Plan). The 2000 Plan became effective on the date
the underwriting agreement for the initial public offering was signed. Under the 2000 Plan, 5,292,621 shares of the Company's common stock have been authorized for issuance, including shares currently
reserved under the 1999 Plan.

As
of December 1, 2000, the Company granted to certain employees of the Company 406,060 options to acquire shares of the Company's common stock at an exercise price of $14.00 per
share and 47,000 options to acquire shares of the Company's stock at $16.00 per share.

In
2001, the Company granted to certain employees and members of the Board of Directors 458,300 options to acquire shares of the Company's common stock at exercise prices between $10.00
and $37.95.

In
2002, the Company granted to certain employees and members of the Board of Directors 1,643,055 options to acquire shares of the Company's common stock at exercise prices between $6.40
and $26.32.

F-19

---

The balance of the above options granted vest 25% upon the first anniversary of an employee's employment and thereafter ratably in equal monthly installments for the next
36 months (four equal annual installments upon the completion of each year of service over a four-year period for outside directors). On an annual basis, outside directors can elect
to utilize a portion of their annual compensation to acquire an option grant to acquire shares of the Company's common stock at an exercise price equal to one-third of the fair market
value each January 1. Such options vest in equal monthly installments over a 12-month period. The options have a term of 10 years from the date of grant. The difference
between the option exercise price and fair value of the Company's common stock was recorded as deferred stock-based compensation and is being amortized to expense over the vesting periods of the
related stock options on an accelerated basis using the graded vesting method.

Stock-Based Compensation

In connection with the sales of common stock to certain employees and the granting of stock options to certain employees and the Company's outside directors on
February 5, 1999, the amount of related compensation to be recognized was determined by the Company to be the difference between the stock purchase or option exercise price and the fair value
of the Company's common stock at that

F-20

---

date. For the common stock sales and the stock options which were vested as of their date of grant, the related compensation was expensed in full as of February 5, 1999. For the stock options
which were not vested as of their date of grant, the related compensation was recorded as deferred stock compensation which is classified as a reduction of shareholders' equity and is being amortized
to expense over the vesting periods of the related stock options.

Stock-based
compensation charges were comprised of the following components:

The
Company estimates that amortization of deferred stock-based compensation, based upon stock options granted and forfeited during the year ended December 31, 2002 in addition to
stock options outstanding at December 31, 2002, will approximate $81,000 in 2003 and $13,000 in 2004.

Stock Purchase Plan

On September 5, 2000, the Company's Board of Directors adopted and the shareholders approved an Employee Stock Purchase Plan (Purchase Plan). The Purchase
Plan became effective on the date the underwriting agreement for the offering was signed. Under the Purchase Plan, 330,000 shares of the Company's common stock were reserved for issue. The share
reserve automatically increases on the first trading day of each January by 1% of the total number of shares of the Company's common stock outstanding on the last trading day of each preceding
December. The increase in the share reserve is not to exceed 550,000 shares. The shares are available for purchase through overlapping offering periods with a maximum duration of 24 months. The
initial offering period began the day the underwriting agreement for the offering was signed and ended in October 2002. Subsequent offering periods begin on the first business day in May and
November of each year. Each offering period consists of a series of successive six-month purchasing intervals. Employee share purchases are funded through payroll deductions not to exceed
15% of earnings. The purchase price of shares at each purchase date is the lesser of 85% of the fair market value of the shares on the purchase date or 85% of the fair market value per share on the
start date of the offering period. During 2002, 149,216 shares had been purchased under the Purchase Plan.

13. Income Taxes

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial statement purposes
and the amounts used for income tax purposes.

The Company leases certain facilities and equipment under capital and operating leases. Certain leases contain renewal and purchase options. Rental expense was
approximately $2,830,000, $3,579,000 and $3,591,000 for 2000, 2001 and 2002, respectively.

Through
September 2000, the Company leased on a month-to-month basis a facility and parking lot from Santa Monica Properties Partnership (SMPP) which is
owned by various shareholders of the Company. Total payments to SMPP were $136,000 in 2000, and are included in rent expense shown above.

Contingencies

In May and June, 2002, the Company was named as a defendant, together with certain of our current or former board members and officers, in four substantially
identical class-action lawsuits filed in the United States District Court for the Central District of California. In September 2002 an amended and consolidated complaint was filed and is
serving as the operative complaint in this litigation. The lawsuit
purports to state claims on behalf of an alleged class of investors who bought our stock in the open market between December 8, 2000 and April 15, 2002 ("Class Period"). The lawsuit

F-23

---

alleges that the market price of our stock was artificially inflated during the Class Period as a result of alleged misrepresentations made in violation of the Securities Act of 1933 and the
Securities Exchange Act of 1934 in connection with our initial public offering of common stock and subsequent public disclosures. The lawsuit alleges, among other things, false and misleading
statements about our compliance with certain regulatory requirements imposed by the California Department of Health Services and the federal Centers for Medicare & Medicaid Services. Plaintiffs
seek compensatory damages, including interest, costs and expenses, attorneys' fees, and other relief. In October 2002 we filed a motion to dismiss the amended complaint, and in
February 2003 the court ruled on the motion, dismissing some claims and not dismissing others. In response to the judge's ruling, we expect plaintiffs to file an amended complaint in
March 2003. We have provided notice to our directors and officer's insurers, and believe that we have insurance applicable to defense of the lawsuits. We also believe that the claims against us
and our current and former officers and directors are without merit, and will vigorously defend such actions.

A
former employee of Specialty Laboratories Asia Pte. Ltd., a Singapore corporation, or SLA, has obtained a judgment of $350,000 against SLA and a default judgment of $1,950,000
in a wrongful termination action against SLA filed in Singapore. The former employee has filed an action against SLA in California to attempt to collect on the Singapore judgment and has obtained a
default judgment of $2,500,000 against SLA in California. The former employee has also served discovery upon the Company and certain of its directors and officers. No overt allegations of any material
liability have been made against the Company. The Company's management believes that any claim against the Company or its directors and officers in connection with these judgments, if made, would be
without merit and the Company will vigorously defend such action.

A
former officer of the Company previously filed an action in federal district court against the Company and two of its officers alleging violations of federal and state securities laws
and other causes of action in connection with the sale of the Company's common stock by the former officer and the Company's application of its insider trading policy. The Company's motion to compel
arbitration was granted, and one of the individual defendants has subsequently been dropped from plaintiff's claims. The matter has been submitted to binding arbitration before a former federal judge,
who recently granted the plaintiff a continuance. We expect the matter to be heard by the arbitrator sometime in 2003. Management believes the claims to be without merit and will vigorously defend
such action.

The
Company is from time to time subject to claims arising in the ordinary course of business. These claims have included assertions that the Company's assays infringe existing patents;
however, none of the claimants have filed litigation against the Company. The Company intends to defend vigorously any such litigation that may arise and to assert all available defenses to
allegations of patent infringement that would be available to the Company. The ultimate resolution of all such proceedings would not materially affect the Company's financial position, results of
operations or cash flows, however, such liability could be material to net income of a future quarter.

Commitments

In September and October 2000, the Company entered into employment agreements with five employees, two of which resigned as part of the 2002 reductions in
workforce (see Note 4. Restructuring Charge). The agreements with the other three employees, which provide in the aggregate

F-24

---

for annual base salaries of approximately $635,000 provide that if two of the employees are terminated for other than cause during the first three years of their contracts, the Company will pay their
salaries for a one-year period subsequent to their severance. For the third employee, if the employee is terminated for other than cause or voluntarily resigns at any time after
January 31, 2005, the Company will pay his salary for a six-month period subsequent to his severance. If any of the five employees are terminated for cause, no further payments are
due to them under the contracts.

In
May 2002, the Company entered into an employment agreement with a new employee. The agreement provides that if the employee is terminated for other than cause or if he resigns
for good reason during the first two years of employment, the Company will pay the base salary of $420,000 and a bonus for a one-year period subsequent to the severance. If after two years
of employment, the employee is terminated other than for cause or if he resigns for good reason, the Company will pay the base salary for a two-year period and a bonus for a
one-year period subsequent to his severance.

Other
executive officers are generally provided with an offer of employment at the time of hiring, which provides for six to nine months of severance pay in the event the employees are
terminated without cause. Four employees have this type of offer-letter which provides in the aggregate for base salaries of approximately $429,000.
