PART I.

ITEM 1. BUSINESS

Overview

Specialty Laboratories is a leading hospital-focused clinical reference laboratory, performing highly advanced, clinically useful testing services for hospitals,
laboratories and physician specialist's nationwide. We believe we offer one of the most comprehensive menus of esoteric assays in the industry, many of which have been developed or enhanced 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 by generally not competing for routine
testing 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 27027 Tourney Road, Valencia, California 91355.

We
maintain a World Wide Web site at www.specialtylabs.com. We make available free of charge through our web site our annual reports on Form 10-K, quarterly reports on
Form 10-Q, current reports on Form 8-K, and amendments to those reports filed or furnished to the SEC as soon as reasonably practicable after filing with or
furnishing to the SEC. We also make available on our website copies of our Audit Committee Charter, Compensation Committee Charter, Nominating Committee Charter, Code of Conduct/Ethics and Corporate
Governance Guidelines, copies of which are also available in print to any shareholder upon request. 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

1

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.



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 generally 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. 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 or modified 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, 2004, approximately 31% 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.



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 85% 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 perform drug resistance testing by phenotyping. In 2003, we developed in collaboration with Tm Bioscience Corporation an improved genetic screening test for Cystic Fibrosis (CF) and
Cystic Fibrosis carrier status.



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.

Products and Services

We perform all of our testing services at our laboratory facility in Valencia, 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 a comprehensive menu of esoteric assays. 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 27% of
our net revenue for the year ended December 31, 2004. Broadly speaking, molecular diagnostics includes all test procedures incorporating or identifying DNA- or RNA-based
targets. This includes assays detecting

4

---



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 more than five million Americans, of whom nearly four million are chronically infected. In this market, we offer more than 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, 2004, approximately 31% 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, 59 of our esoteric assays currently account for a substantial portion of our net revenue. These assays, on a net revenue basis, accounted
for approximately 47% and 45%, respectively, of our net revenue for the years ended December 31, 2004 and 2003. 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 seven marketing professionals and approximately 36 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 three 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.



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 us as their reference laboratory. In 2003, we launched the next generation Outreach Express®, a proprietary, Web-based laboratory test
order and result reporting system, providing hospital organizations with a tool for strengthening the laboratory services they provide to physician offices, medical groups and affiliated healthcare
organizations. 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 periodically 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, rheumatology, genetics, and cardiology. We present our research at scientific meetings and we exhibit at more than 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.

Sales Strategy

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
revenue by class of customer:

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. In addition to several small 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 periodic administrative fee to the group purchasing organization.



For the year ended December 31, 2004, independent laboratories represented approximately 30% 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.



For the year ended December 31, 2004, physician specialists comprised approximately 4% of our net revenue and represented approximately 352 accounts.
Currently, there are more than 200,000 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, international and industrial accounts. Altogether, these testing services comprised
approximately 5% of our net revenue for the year ended December 31, 2004.

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® and Outreach
Express® products collect 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 85% 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

8

---



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. An upgraded version of Outreach Express® became available to all customers in October 2003.

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. 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 the 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 $1.7 million per year for the past three years. Our R&D efforts enable us to grow revenues, increase market share and provide the opportunity for premium pricing.

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.



During recent years, we licensed intellectual property that has enabled us to commercialize several new assays. Among them are CF-70, an expanded
panel cystic fibrosis assay that we license from Tm Bioscience; 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
the past, we have also 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.

NIH
has not filed suit against us, and based on our communications with NIH and our understanding of their patent rights, we do not expect such a suit to be brought; however, 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 a suit 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, we could be forced to pay
substantial damages, including possible treble damages for allegations of willful infringement.

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. In 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. On August 15, 2003 Specialty entered into a letter agreement with Chiron Corporation, and a separate Settlement and License Agreement with the
Diagnostics Division of Bayer Healthcare LLC of Tarrytown, New York. Under the agreements, Specialty made payments to Bayer and Chiron for alleged past infringement of several Chiron patents by
certain Hepatitis C Virus ("HCV") and Human Immunodeficiency Virus ("HIV") testing performed by us.

Under
the agreement with Chiron, Chiron agreed not to assert its patent rights, or bring any claim against us for any alleged infringement relating to nucleic acid clinical assays for
the detection, quantitation, genotyping and/or phenotyping of HCV and HIV occurring at any time prior to

11

---



October 15,
2003. In the agreement with Bayer, Bayer agreed to indemnify Specialty in the event Chiron brings such a suit or claim against Specialty for infringement of Chiron's patent rights
with respect to HCV and HIV testing during this period. Bayer also provided Specialty with a royalty-bearing non-exclusive sublicense to perform laboratory-developed HCV and HIV nucleic
acid assays. Separately, Specialty agreed to modify its supply agreement with Bayer to convert to using Bayer products, which are licensed under certain Chiron patent rights, for HCV and HIV
genotyping. 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 and/or
enter into appropriate licenses which may cause us to pay substantial damages or royalties, and could prohibit or restrict us from selling our assays."

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 Prometheus Laboratories 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, or ARUP, generally lack the advantages of larger commercial laboratories and compete with us in the esoteric market.

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 and process 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 material approvals and licenses for

12

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) 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.

13

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, 2000 through 2005, our shareholders' equity and total assets exceeded $100 million, and we are therefore 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.

Extensive
regulations implementing and interpreting certain provisions of the Stark Law have been released by CMS. 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 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

14

---



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.

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 or processing 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 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, 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), which subject clinical laboratories to national standards. Because of the location of our laboratory in Valencia, licensure is also required under the laws of
the State of California. Since we perform testing for patients from all states, we hold licenses in additional states where such licensure is required by local state law, including Florida, Maryland,
New Hampshire, New York, Pennsylvania, Ohio, West Virginia, and Rhode Island. We will apply for licenses in other states as needed, and if and when other states require licensure of
out-of-state laboratories, we may need to obtain additional state licenses. Our laboratory is also accredited 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. 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.

We
previously received sanctions based on alleged failures to comply with certain state and federal regulations, and we will be subject to additional future inspections. We can provide
no assurances that our facilities will pass all future inspections conducted to ensure compliance with federal or any other applicable licensure or certification laws.



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 two Compliance Officers 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.



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

16

---



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 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. 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 New York residents. This level of scrutiny delays test availability in New York.



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 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 and Medicaid 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. During 2002, 2003 and 2004 such direct billings by us to Medicare
as a percentage of our net revenue accounted for approximately 2.9%, 4.0% and 4.6%, respectively. As a percentage of our net revenue, billings by us to Medicaid during 2002, 2003 and 2004 accounted
for approximately 1.9%, 2.5% and 2.6%, respectively. 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

17

---



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 could be expected that such fee schedules would 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 eliminated consumer price index increases to the national cap and local fee schedules from 1998 through 2002 and 2004 through 2008, 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.

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. For example, the 2003-2004 California State Budget called for a 5% reduction in Medi-Cal reimbursement effective January 1, 2004.
However, laboratories were exempted from those cuts, and the cuts were not made to other providers based on a court injunction issued in December 2003 citing potential beneficiary access
problems. Nevertheless, some cuts to laboratory payments resulted from the enactment of an across the board cap on Medi-Cal reimbursement for laboratory services to a rate of 80% of the
Medicare payment rates for the same tests. While reductions to Medi-Cal payments to laboratories and other providers were again proposed for the 2004-2005 budget, concerns over
the injunction led to no cuts being made. A major redesign of the Medi-Cal program has been proposed as part of the 2005-2006 budget. Direct reductions to provider payments are
not part of this proposed redesign. However, an increased emphasis on managed care programs would shift Medi-Cal enrollees into managed care programs, which typically pay less to
laboratories than does the Medi-Cal fee-for-service program, and a proposal to impose premiums on certain Medi-Cal enrollees could cause them to elect
not to have Medi-Cal coverage at all. 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. The Medicare Prescription Drug, Improvement and

18

---



Modernization
Act delayed implementation of the CMS rules until January 1, 2007 for hospitals who had qualifying outsourcing contracts for pathology services in place as of July 22,
1999. 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. The Office of the Inspector General of the Department of Health and Human Services has proposed regulations which would
implement this authority. As proposed, certain discounts we negotiate with our private clients would be taken into account by these regulations in setting the maximum amounts that we could bill to the
Medicare program. The regulations could therefore require us to lower our charges to the Medicare program or to increase our charges to our clients, or a combination of both. We cannot predict what
effect, if any, this rule and its implementation will have on our business. 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.

Contracts for Laboratory Services.The Secretary of the Department of Health and Human Services has been directed to conduct
several pilot projects to examine payment alternatives to the traditional Medicare Part B fee schedule. Among the projects is a competitive demonstration project for
independent laboratory services. The Secretary is to provide a progress report to Congress by December 31, 2005, although no date has been set for implementation. 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
moved forward in implementing a contracting program. This first phase of Medi-Cal laboratory contracting does not contemplate a competitive bidding process. We have submitted an
application to contract with the Medi-Cal program pursuant to its submission protocol. While it is expected that contracts will be awarded to many laboratories within California, there can
be no assurance that we will be awarded a contract.

There
is at least one competitive Medicaid bidding demonstration project underway that may result in only one laboratory being reimbursed for the provision of laboratory services to an
entire state's Medicaid population. It is possible that in the future, other competitive bidding demonstration projects in other states or pursuant to other Medicaid programs may also award contracts
to a sole-source vendor. In the event we are not allowed to participate in such awarded competitive bidding contracts or

19

---



are
otherwise not awarded such contracts, we may not be reimbursed for testing we perform for Medicaid patients in these states.

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. There has also been a push to enroll more Medicare beneficiaries in Medicare HMO plans. 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.

So
far, Medi-Cal laboratory contracting has not set negotiated payment rates. However, to obtain contracts to perform Medicare, Medi-Cal or Medicaid services in
the future, it might be necessary for us to engage in competitive bidding and to agree to substantial reductions in our payments from these programs. Such contracts may be exclusive and laboratories
which do not hold such contracts may be denied access to the Medicare/Medi-Cal/Medicaid 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 our customers or we 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 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

20

---



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 still have to directly address HIPAA regulations
in other circumstances.

In
most circumstances, entities covered by HIPAA must have been or 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. While we believe that we are in compliance in all material respects with all currently applicable state and federal laws and regulations governing the
confidentiality, dissemination and use of medical record information, including HIPAA, our failure to comply could subject us to fines and penalties, and have a detrimental effect on our business. We
may be subject to inspections or investigations by state or federal regulatory entities that enforce privacy laws and regulations, and we can provide no assurances that we will be found fully
compliant with HIPAA or other related laws and regulation. 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.

Employees

As of December 31, 2004, we employed 689 individuals, including 136 in administration and clerical functions, 55 in sales and marketing, 32 in information
technology and 454 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 our 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.

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 highly regulated 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 regulated by California, New York and various other states. We are accredited by the College of American Pathologists, a private accrediting agency, and are also subject
to their accreditation requirements and evaluation. Our failure or inability to comply with CLIA, state or other applicable requirements could result in various penalties, including restrictions on
tests 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.

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. Based upon these
inspections, and

22

---



findings
that we were permitting unlicensed personnel to perform and supervise clinical laboratory testing in violation of California law, in 2002 CDHS and CMS separately imposed sanctions, including
notice of revocation of our CLIA certificate, cancellation of our approval to receive Medicare and Medicaid payments for services performed, and civil money penalties.

After
filing supplemental documentation supporting our compliance with the applicable requirements with CDHS and CMS, CDHS conducted additional unannounced inspections, and we provided
additional documentation supporting our compliance with CDHS requirements. CDHS subsequently indicated that we were in substantial compliance with California clinical laboratory law, and CMS also
notified us that it had deemed Specialty in compliance with all condition level requirements of CLIA. CDHS and CMS assessed civil money penalties in excess of $700,000, and we did not challenge the
penalties.

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
and/or Medicaid 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. 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 a
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.

The
FDA has also asserted that its jurisdiction includes the ability to inspect our facilities in connection with certain testing we do for blood donation and collection centers. An
inspector from the FDA conducted an unannounced site inspection of our laboratory facilities in 2003 and 2004 in connection with this testing for blood centers. The FDA inspector's report of these
inspections did not indicate any material issues or deficiencies of our facilities. However, we will likely be subject to future FDA inspections, and no assurances can be given that our facilities
will satisfactorily pass all such inspections. Any inability to comply with applicable FDA regulations could result in substantial monetary penalties, revocation of our FDA registration, suspension or
cancellation of our ability to conduct testing for blood donation and collection centers, and could divert a substantial amount of management's time and resources, and any such action could materially
harm our business.

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

23

---



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.

Our accessions have declined in the past, and may decline again in future periods.

Because of uncertainty surrounding the sanctions imposed on us by CMS in 2002, 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 in 2002 and 2003. While our
accession volumes rose in 2004, we cannot provide any assurances that our clients will continue sending us specimens for testing due to a variety of factors, including competition from other reference
laboratories and our clients internalizing testing we now perform for them. We also cannot provide assurances that our accessions will continue increasing, and they may decline again. If our
accessions decline again, or if they fail to continue increasing, it could materially adversely affect our business, financial condition, results of operations and prospects.

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 and ARUP, also compete with us by providing specialized testing services. They often refer assays to us that they
either cannot or elect not to perform themselves. During 2002, we saw a significant decline in test volumes referred to us from our competitors. Sales to our competitors were approximately 4% of our
net revenue for each of the years ended December 31, 2002, 2003 and 2004. 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 April 2002, Quest announced that they had entered into a definitive agreement to acquire Unilab
Corporation. As a result, we experienced a significant decline in testing volumes sent to us from Unilab. We previously experienced a significant reduction in volume from Quest, LabCorp, Mayo and
ARUP, and if these or other laboratories decide to reduce or discontinue purchases of our assays for competitive or other reasons, it will reduce the number of our accessions and reduce our net
revenue.

The clinical laboratory industry is intensely competitive, and we may be unable to successfully compete.

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 revenues.

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 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, acquired American Medical Laboratories Incorporated, a
national provider of esoteric testing to hospitals and specialty physicians, Clinical Diagnostic Services, Inc., a provider of routine and esoteric testing, and Unilab Corporation, a leading
clinical testing laboratory. LabCorp acquired Dianon Systems Inc., a leading U.S. provider of anatomic pathology and oncology testing services. More recently, LabCorp announced the acquisition
of U.S. Labs, a cancer testing provider. 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
business 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

25

---



vary
depending on a number of factors, many of which are outside our control, including, but not limited to:



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, including 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 2002 and have since been
settled. Litigation of this type is often expensive and diverts management's attention and resources, and we can provide no assurance that we will not face any similar future actions.

We
plan to expand our sales and marketing 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" above.

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 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

26

---



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. In 2002,
2003 and 2004, third party payors accounted for approximately 6.6%, 8.3% and 9.3%, respectively, of our net revenue. 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.

Requirements for competitive bidding procurement of Medicare/Medicaid laboratory testing services could exclude us from providing testing to certain patients.

Proposals have been made to require competitive bidding procurement of Medicare laboratory testing services. The Centers for Medicare and Medicaid Services (CMS)
has recently selected a vendor to begin a demonstration project of a competitive bidding for clinical laboratory services, although the project has not yet begun. A competitive Medicaid bidding
proposal was made in Florida (and later withdrawn) that would permit only one laboratory to provide services as the sole vendor under the contract. It is possible that other future competitive bidding
demonstration projects may also award the contract to a sole-source vendor. We can provide no assurances that future competitive bidding processes will allow us to compete successfully for
the Medicare/Medicaid contracts. In the event that we are not successful in the competitive bidding process, or are otherwise not allowed to participate in such awarded competitive bidding contracts,
we may not be reimbursed for testing we perform for Medicaid patients in these states. Any restriction on our ability do testing for Medicare/Medicaid patients, or be reimbursed for testing we perform
for such patients, could materially affect our revenue and business. Any restriction on our ability to do testing for Florida Medicaid patients could also significantly negatively affect the amount of
business we receive from our Florida clients, as such clients might be less inclined to divide the work they send to outside reference laboratories. Loss of business from our Florida clients could
materially affect our revenue and business.

Increasing restrictions in government-funded payment programs, and reductions in government-funded spending on laboratory testing reimbursement, could restrict or exclude us
from providing testing to certain patients, and could materially affect our revenue and business.

Recent state and federal budget constraints have forced cuts in many government-funded payment and reimbursement programs. For example, in 2004, California
implemented a reduction of approximately 10% in the reimbursement schedule for laboratory testing performed for Medi-Cal patients. Florida has recently proposed an alternative to a
competitive bidding sole-source process that would reduce its fee schedule by 10%. Other states may make similar or larger reductions in reimbursement schedules. Such reductions could
cumulatively have a material negative effect on our business and net revenue. Furthermore, some states are implementing increased restrictions on healthcare providers' access to such payment programs,
including sole-source contracts and restrictions based on past regulatory issues. While we currently believe that such restrictions should not exclude us from participation in such
programs, we can provide no guarantees that we will not be excluded from, or have reduced access to, such programs. For example, because of our past regulatory issues with the California Department of
Health Services and the Centers for Medicare and Medicaid Services, we could be prohibited from bidding on certain bidding projects or proposals. In the event we are excluded from, or have reduced
access to, any government-sponsored payment program, it could have material negative effect on our revenue and on our business.

Our effective tax rate may fluctuate and we may not be able to fully realize all or a portion of our deferred tax assets.

We reported $5,864,000 of deferred income taxes (current and long-term) in the December 31, 2004 balance sheet, with approximately $15,187,000
of this amount related to federal and state net operating loss carryforwards (NOL's). Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes", requires that deferred tax assets be reduced by a valuation allowance if it is more likely than not that some portion of the deferred tax asset will not be realized.
Our valuation allowance totaled approximately $7.2 million at December 31, 2004. Realization of the NOL's generated through December 31, 2004 is dependent on our ability to
generate approximately $33.5 million of federal and $42.8 million of state ordinary income in future years. We cannot provide any assurances that the NOL's will be realized. Inability to
generate the necessary ordinary income, and our inability to realize the NOL's, could have a material adverse effect on our results of operations in future quarters. The federal NOL's begin expiring
in 2024 and the state NOL's begin expiring in 2014.

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 and certain other key personnel. While we have employment agreements
with our executive officers and other members of our current senior management group, the loss of the services of any of these executive officers or other key employees could hurt our business.

On
February 14, 2005 we announced the departure of Douglas S. Harrington, M.D., our chief executive officer and laboratory director, effective March 29, 2005. While we have
engaged a search firm to assist us in locating a new chief executive officer, we may not be able to promptly identify and recruit a suitable candidate.

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 personnel at our new laboratory and operational headquarters facility in Valencia, California, which is approximately 30 miles from our former laboratory
location in Santa Monica, California.

Any
failure to retain and attract necessary personnel, including a new chief executive officer, could hurt our business and impair our growth strategy.

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, Consorta, MedAssets HSCA (formerly Health Services Corporation of America), Managed Healthcare Associates (MHA), Novation, Premier Purchasing Partners, and Shared Services
Healthcare (now affiliated with MedAssets HSCA). We are typically granted non-exclusive provider status under

28

---



these
contracts. Our contracts with our group purchasing organizations will expire at various times from 2005 to 2009.

If
our agreement with any group purchasing organization is terminated or not renewed, we may not 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 field of specialized clinical laboratory testing 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 our competitors, or other third parties. For instance, a diagnostic manufacturing company could release an instrument or technology that would make it cost-effective for our
customers to perform complex assays internally, rather than through us. If these or other advances in technology allow other entities to perform testing we currently perform, it could result in a
decreased demand for our assays, and our assay volume and net revenue would decline. We may also be forced to lower prices on our assays to reduce the likelihood that other entities, including our
clients, will perform such testing. Any assay volume, test price or revenue reductions would significantly harm our business.

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 and enacted at both the state and federal levels. For example, the Health Insurance
Portability and Accountability Act of 1996, known as HIPAA, and regulations promulgated under HIPAA require certain healthcare providers and holders or users of electronically transmitted patient
health information to 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. The HIPAA regulations required that covered entities (including us) be in compliance with the privacy regulations on or before 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 regulations under HIPAA. We have implemented encryption technology to protect patient medical information, but use of encryption technology does
not guarantee the privacy and security of confidential information.

29

---



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 are in compliance in all material
respects with the applicable HIPAA regulations, our failure to comply could subject us to fines and penalties, and have a detrimental effect on our business. We may be subject to inspections or
investigations by state or federal regulatory entities that enforce privacy laws and regulations, and we can provide no assurances that we will be found fully compliant with HIPAA or other privacy
laws and regulations. Any findings of non-compliance with HIPAA or other privacy laws and regulations could significantly harm our client's confidence in our processes relating to the
confidentiality, dissemination and use of medical record information, and could significantly harm 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 specialized assays at premium prices until 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. We may also be forced to lower prices on our assays to reduce the likelihood that other entities, including our clients, will perform testing we currently
perform for them.

Our average selling price has fluctuated, and may go down depending on the ordering patterns of our clients.

As our clients internalize some tests we perform for them, or as they find alternative sources of testing, they may change the mix of testing sent to us. If our
clients send us fewer higher-priced tests, the average selling prices for our assays could drop, and our revenue could be negatively affected. Our average selling price has gone down previously, and
we can provide no guarantees that it will grow in the future, and it may go down again. Our business and potential profitability could be significantly affected if we are not able to grow our average
selling price.

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 specialized 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. We can provide 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

30

---



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 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 revenue.

Our success depends, in part, on the continued and uninterrupted performance of our information technology systems, including our DataPassport®, Data
PassportMD® and Outreach Express® suite of products, and our laboratory information system. 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, or that reduces the attractiveness of our products to our
customers.

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 our information technology 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 provider, Qwest Communications in Burbank, California, and we
cannot control the maintenance and operation of the 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. 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 information technology 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
business.

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 may lose this competitive advantage, and as a result, may be unable to maintain or increase our business growth.

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 59 assays. Net revenue from these 59 assays comprised approximately 47% of our total net revenue for the
year ended December 31, 2004. If

31

---



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 and consultants, 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 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 and/or enter into appropriate licenses which may cause
us to pay substantial damages or royalties, and could prohibit or restrict 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. 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
also received letters from Chiron Corporation ("Chiron") in February 1998, and the National Institute of Health (NIH) in 2000-2003 claiming that some of our assays
may violate their patents. In August 2003 we reported that we had entered into a letter agreement with Chiron that called for us to make payments to Chiron for alleged past infringement of
Chiron patents by certain Hepatitis C Virus ("HCV") and Human Immunodeficiency Virus ("HIV") testing performed by us, and Chiron agreed not to assert its patent rights, or bring any claim against
Specialty for any alleged infringement relating to nucleic acid clinical assays for the detection, quantitation, genotyping and/or phenotyping of HCV and HIV occurring at any time prior to
October 15, 2003. We cannot provide any assurances that the NIH or other patent holders will not bring suit against us in the future for alleged patent infringement. 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.

32

---



In
June 2004 we became aware of a lawsuit filed against us in the U.S. District Court for the Southern District of California by Prometheus Laboratories, Inc.
("Prometheus"). The complaint alleged infringement of Prometheus' patent rights by a new assay we announced for the monitoring of drug levels in connection with the treatment of Inflammatory Bowel
Disease. Based partly on the threat of the litigation, and the service disruption the lawsuit could have on our clients, we chose not to make this new assay available to our clients, and the matter
with Prometheus was resolved without admission of liability or the payment of any settlement amounts. Prometheus has since dismissed their lawsuit against us.

Patent
infringement suits can be very 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 such 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. Licenses for such patents may require the payment of
material sums of money as license fees and royalties, including fees and royalties for past infringement. 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, we could be forced
to pay substantial damages, including possible treble damages. 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. 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 securities as consideration, our
shareholders' equity 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 or incur
significant indebtedness. 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.

33

---



We may need or elect to raise additional funds to fund our operations and activities beyond the next year or to consummate acquisitions of other businesses, assets or
technologies.

While we expect existing cash and cash equivalents, short-term investments, and lines of credit will be sufficient to fund our operations, meet our
capital requirements to upgrade our IT infrastructure, support our growth, and allow strategic technology licensing and acquisitions for the next year, and 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. 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 additional equity securities 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.

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 specialized 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 specimen processing facilities, our clinical laboratory, and our corporate offices may be affected by catastrophes such as fires, earthquakes or sustained
interruptions in electrical service. Earthquakes are of particular significance to us because our current clinical laboratory facilities are located in Valencia, California, an earthquake-prone area.
In the event our existing facilities or equipment are affected by man-made or natural disasters, we may 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.

34

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

Our specimen processing facilities, our clinical laboratory, and our corporate offices are located 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 power generators for partial backup of our laboratory operations 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 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 may be harmed by terrorist attacks on the U.S. For example, after the September 2001 terrorist attacks transportation
systems and couriers that we rely upon to receive and process specimens were 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 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.

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

Our principal shareholder is the Specialty Family Limited Partnership, whose sole managing general partner, James B. Peter, M.D., Ph.D., is a member of our board
of directors. Specialty Family Limited Partnership, together with Dr. Peter, currently beneficially own approximately 61% 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.

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

35

---



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

During 2001, we made the decision to consolidate our laboratory and administrative functions in a single building. In December 2001, we purchased a 13.8
acre site in Valencia, California. We began constructing a 198,000 square foot facility in the second quarter of 2002. The construction project was originally scheduled to be completed in the second
half of 2003; however, in October 2002, we announced that we would postpone the move to our new facility in Valencia until the second half of 2004 and halt the construction project once the
Core and Shell of the building was completed. The Core and Shell was substantially completed in January 2003, with the remaining work of punch lists and sign-off of systems
concluded in April 2003.

On
February 11, 2004, we signed an agreement for the sale and leaseback of the Valencia facility with Lexington Corporate Properties Trust (Lexington), a real estate investment
trust. Under the terms of the agreement, Lexington purchased the existing facility for $47.0 million. We planned to complete the construction project and entered into a 20-year
lease for use and occupancy of the facility. The sale and leaseback transaction was completed on March 18, 2004.

Lease
payments began in September 2004. Based on interest rates in effect on December 31, 2004, rent expense for the new facility is expected to be approximately
$4.6 million per year, approximately $2.0 million higher than comparable costs at our former facilities in Santa Monica, and includes the effect of scheduled rent increases in future
years under our 20-year lease. We expect certain other operating expenses at the Valencia facility, such as utilities and property taxes, may also
exceed cost levels incurred at the former Santa Monica facilities by as much as $2.0 million annually, based primarily on the considerably larger size of the Valencia facility.

During
the third quarter 2004, we substantially completed construction activities and relocated our administrative functions from Santa Monica to our facility in Valencia. The move of
our laboratory functions from the facilities in Santa Monica to Valencia was substantially completed during the fourth quarter 2004. During 2004, we incurred approximately $4.7 million in costs
to relocate our operations to our new facility in Valencia. These costs relate to planning and executing the physical move, the disposal of equipment not used in the new facility, the remaining rental
obligation on the closed Santa Monica laboratory, the required validation of laboratory equipment upon arrival, charges associated with leaving our former Santa Monica facilities and bonuses paid to
personnel who contributed to the successful relocation process. During the first quarter 2005, we anticipate to incur additional expenses associated with the closure of the Santa Monica facilities of
approximately $500,000.

We
also operate one stand-alone triage collection and processing center in Shrewsbury, Massachusetts to serve Boston area customers. This facility contains 2,890 square feet and is
leased at approximately $52,000 per year. In early 2004, we extended our lease agreement to expire in March 2005, and we have since negotiated an extension on a month-to-month basis.

In
addition, we lease a 60,000 square foot building in Memphis, Tennessee, and in June 2002, we subleased the facility for the period July 1, 2002 through
September 14, 2007, the end of our lease

36

commitment.
We recorded charges in 2000 and 2002 for future unrecoverable lease costs. Assuming no change in the sublease, no future costs should be incurred.

ITEM 3. LEGAL PROCEEDINGS

In addition to the California state and federal investigations described in "BusinessGovernment RegulationCertification and Licenses"
and "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", we are involved in
various legal proceedings arising in the ordinary course of business.

Securities Litigation: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, and subsequently consolidated
as "In re Specialty Laboratories Securities Litigation". The lawsuit purported 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 alleged 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 alleged, 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 sought compensatory damages, including interest, costs and expenses, attorneys' fees, and other relief. Plaintiffs have
filed several amended complaints, and we in turn have filed motions to dismiss these complaints. The court ruled on these motions, dismissing some claims and not dismissing others, and allowed
plaintiffs to proceed with their claims against the Company and several current and former officers and directors for alleged violations of both the Securities Act of 1933 and the Securities Exchange
Act of 1934. We provided notice to our directors and officer's insurers, and believe that the claims against us and our current and former officers and directors are without merit, and intend to
defend these lawsuits vigorously. On June 14, 2004, we announced an agreement in principle to settle the consolidated lawsuits for $12 million, which is to be paid fully by our insurance
carriers. On December 22, 2004, the court entered a final order approving the settlement and providing for notice to shareholders. As the settlement and defense costs are being paid by our
insurance carriers, we do not anticipate any costs associated with the defense or settlement of the claims to have a material impact on our finances.

Specialty Laboratories Asia:Specialty Laboratories Asia Pte. Ltd., a Singapore corporation, ("SLA"), is 60% owned by
our wholly-owned subsidiary, Specialty Laboratories International Ltd., a British Virgin Islands corporation ("SLIL"). 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 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.

Singapore Litigation:In December 2003, we were served with an action in which we are named as a defendant, together
with certain of our former officers, SLIL, and multiple other parties located in Singapore and India, in a lawsuit brought in the High Court of the Republic of Singapore by Dragon Investment Company
("Dragon"), one of the shareholders in SLA. Dragon has also brought the lawsuit in the name of SLA as a derivative action. The lawsuit alleges, among other things, that SLA and

37

---



Dragon
suffered damages as a result of the winding up of the affairs of SLA and disposition of its assets. The lawsuit also alleges that certain of the defendants breached certain written agreements
to allow Dragon to acquire more shares of SLA, that certain of our former officers conspired to run down and dissipate the assets of SLA, and that they fraudulently concealed their actions from Dragon
and the other minority shareholder of SLA. We have provided notice to the applicable insurance carriers. While we believe that we have insurance applicable to the defense of the lawsuits, and continue
to work with the relavent insurance carriers on the coverge issue, such carriers have not yet acknowledged coverage of the matter.

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 and/or enter into appropriate licenses which may cause us to pay substantial damages or royalties, and could prohibit or restrict 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. See "Cautionary Statement Regarding Forward-Looking Statements". 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.

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 one of the most comprehensive menus of specialized assays in the industry, with a test menu comprising thousands of
different assays. Specialized assays are used to diagnose, evaluate and monitor patients and offer important clinical value. Because of their complexity, these assays are often performed by highly
skilled personnel on technologically sophisticated instruments and are therefore offered by a limited number of clinical laboratories.

Our
primary clients are hospitals, independent clinical laboratories and physicians. We have aligned our interests with those of hospitals by generally 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. Through our specialized
testing menu and efforts to educate physicians, we also generate significant revenues from other national and regional clinical laboratories and specialized physician practices. 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.

As
a result of the impact of significant business challenges we faced in 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 was comprised of 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. The charge was comprised of 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 was comprised of
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 a synthetic lease financing arrangement with the banking group led by BNP Paribas.

In
December 2001, we purchased a 13.8 acre site in Valencia, California and began construction during the second quarter of 2002 of a 198,000 square foot facility, which would
enable us to consolidate all of our laboratory and administrative functions in one location. In October 2002, we announced that we would postpone the move from our Santa Monica, California
location to the new facility in Valencia until the second half of 2004. Accordingly, the construction of the new facility was suspended at completion of the Core and Shell of the facility, which was
substantially completed in

January 2003.
We resumed construction of the Valencia facility in early 2004. On February 11, 2004, we signed an agreement for the sale and leaseback of the Valencia facility with
Lexington Corporate Properties Trust (Lexington), a real estate investment trust. Under the terms of the agreement, Lexington purchased the existing facility for $47.0 million. We planned to
complete the construction project and entered into a 20-year lease for use and occupancy of the facility. The sale and leaseback transaction was completed on March 18, 2004.

Lease
payments began in September 2004. Based on interest rates in effect on December 31, 2004, rent expense for the new facility is expected to be approximately
$4.6 million per year, approximately $2.0 million higher than comparable costs at our former Santa Monica facilities without any expansion, and includes the effect of scheduled rent
increases in future years. We expect certain other operating expenses at the Valencia facility, such as utilities and property taxes, may also exceed prior cost levels in Santa Monica by as much as
$2.0 million annually, based primarily on the considerably larger size of the Valencia facility.

During
the third quarter 2004, we substantially completed construction activities and relocated our administrative functions from Santa Monica to our facility in Valencia. The move of
our laboratory functions from the facilities in Santa Monica to Valencia was substantially completed during the fourth quarter 2004. During 2004, we incurred approximately $4.7 million in costs
to relocate our operations to our new facility in Valencia. These costs relate to planning and executing the physical move, the disposal of equipment not used in the new facility, the remaining rental
obligation on the closed Santa Monica laboratory, the required validation of laboratory equipment upon arrival, charges associated with leaving our former Santa Monica facilities and bonuses paid to
personnel who contributed to the
successful relocation process. During the first quarter 2005, we anticipate incurring additional expenses associated with the closure of the Santa Monica facilities of approximately $500,000.

Other
significant developments in the last twelve months included:

On
March 19, 2004, we announced the completion of the sale/leaseback of our future headquarters and laboratory facility in Valencia, California with an affiliate of Lexington
Corporate Properties Trust ("Lexington"). Under the terms of the agreement, the Lexington affiliate purchased the land and existing building, and we will complete the construction and additional
improvements. At the closing, we entered into a 20-year lease for use and occupancy of the facility.

On
March 19, 2004, Frank J. Spina, Senior Vice President and Chief Financial Officer, left the company to pursue other professional opportunities. On April 12, 2004, we
announced the appointment of Kevin R. Sayer as Executive Vice President and Chief Financial Officer of the Company.

On
June 3, 2004, we announced the election of David R. Schreiber, Hubbard C. Howe and Michael T. DeFreece as new Directors of the Company, and that six incumbent Director nominees
had been reelected to the Board of Directors.

On
June 14, 2004, we announced that the Company had reached an agreement in principle to settle securities class action lawsuits brought in the United States District Court for
the Central District of California, and subsequently consolidated as "In re Specialty Laboratories Securities Litigation."

On
September 15, 2004, we announced that Mr. Thomas R. Testman resigned from our Board of Directors. Mr. Testman also served on the Audit Committee and the
Nominating/Corporate Governance Committee. Mr. Testman resigned for personal reasons. On September 15, 2004, we also announced the appointment of Mr. Richard K. Whitney to our
Board of Directors to fill the vacancy resulting from Mr. Testman's resignation. Our Board of Directors also appointed Mr. Whitney to serve on the Audit Committee and the Regulatory
Committee of our Board of Directors.

On
September 29, 2004, we entered into a supplier agreement with Novation, the supply company of VHA, Inc. and the University HealthSystem Consortium (UHC). Under the
agreement, we are

43

named
as one of three authorized providers to make reference testing services available to the more than 1,800 member health care organizations of VHA and UHC.

On
October 28, 2004, we entered into a multi-source group purchasing agreement with Premier Purchasing Partners, L.P., which operates the group purchasing programs of
Premier, Inc. Under the agreement, we are named as an authorized provider of laboratory services to make reference testing services available to the more than 1,500 hospitals and hundreds of
other healthcare facilities.

Critical Accounting Policies

Revenue Recognition

We recognize revenue for each customer order when the following fundamental criteria are met: (i) the testing process for a specific customer has been
completed; (ii) we have no further performance obligation to the customer; (iii) the customer is obligated to pay for services rendered; and (iv) the related fees are
non-refundable. This generally occurs when the assay result is reported to the customer. Our revenue recognition policies are in compliance with Securities and Exchange Commission Staff
Accounting Bulletin No. 101,Revenue Recognition in Financial Statements.

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 receivable amounts based on final
settlements with the third-party payor programs are recorded upon settlement. Such adjustments were not material to our net loss in 2002, 2003 and 2004. In 2002, 2003 and 2004, combined third-party
payor programs, including Medicare and Medicaid, comprised 6.6%, 8.3%, and 9.3%, of our net revenue, respectively.

Expense Recognition

Expenses are recognized as incurred and are generally classified between cost of services and selling, general and administrative expenses. The primary components
of cost of services are salaries and employee benefits, research and development costs, supplies and reagents, equipment rental costs, courier costs, facilities related costs and depreciation of
laboratory equipment and leasehold improvements. Selling, general and administrative expenses include salaries and employee benefits, sales and marketing, information technology, professional fees,
insurance, facilities related costs, depreciation and bad debt expense.

Income Tax Valuation Allowance

In accordance with SFAS No. 109, "Accounting for Income Taxes" ("SFAS 109"), deferred tax assets should be reduced by a valuation allowance if it is
more likely than not that some portion or all of the deferred tax assets will not be realized. The future realization of our net deferred tax assets depends on the availability of sufficient future
taxable income. In making this determination, we consider all available positive and negative evidence and make certain assumptions. We consider, among other things, the overall business environment;
our historical earnings, including our significant pretax losses incurred during the last three years; and our outlook for future years.

We
performed this analysis as of December 31, 2004 and determined that there was sufficient positive evidence to conclude that it is more likely than not that our net deferred tax
assets will be realized. The positive evidence included (1) our expectation that we will report pre-tax book and taxable income in future years; (2) our federal net operating
losses ("NOL's") have never expired unused; (3) our state and federal NOL carryforwards at December 31, 2004 will not begin to expire until 2014 and 2024, respectively; and
(4) our recent losses resulted primarily from a single event (sanctions imposed by CMS in the second quarter of 2002) that was corrected and our operations have

44

---



improved.
We assess the need for a deferred tax asset valuation allowance on an ongoing basis considering factors such as those mentioned above as well as other relevant criteria. Changes in the
assumptions discussed above may have a material impact on our consolidated financial statements. For additional information about income taxes, see Note 14 of the notes to the consolidated
financial statements.

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,Accounting for Stock Issued to
Employees, 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 administrative 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 that were granted to employees and directors prior to December 31, 2000. Based on the number
of outstanding options granted as of December 31, 2004, we do not expect to amortize any deferred stock-based compensation during 2005. We anticipate that the exercise price of the 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.

Recently Issued Accounting Pronouncements

On December 16, 2004, the Financial Accounting Standards Board (FASB) issued SFAS No. 123 (revised 2004), Share-Based Payment, which is a revision
of SFAS No. 123,Accounting for Stock-Based Compensation. SFAS No. 123(R) supersedes APB Opinion No. 25, Accounting for Stock Issued to Employees, and amends SFAS No. 95,Statement of Cash Flows.
Generally, the approach in SFAS No. 123(R) is similar to the approach described in SFAS No. 123. However, SFAS No. 123(R)requiresall share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values. Pro forma disclosure is no longer an
alternative. SFAS No. 123(R) must be adopted no later than July 1, 2005 for calendar quarter companies. Early adoption will be permitted in periods in which financial statements have not
yet been issued. We will utilize the modified prospective method, recognizing compensation cost for share-based awards to employees based on their grant-date fair values from the beginning
of the year in which the recognition provisions are first applied as if the fair value-based method had been used to account for all employee awards. Under this transition approach, compensation cost
will be recognized for all awards granted, modified or settled after the date of adoption as well as to any awards that were not fully vested as of that date. Any adjustments to recognize share-based
liabilities at fair value from the beginning of the year through the date of adoption will be recognized as a cumulative effect of a change in accounting principle. We expect to adopt SFAS
No. 123(R) on July 1, 2005.

As
permitted by Statement 123, we currently account for share-based payments to employees using APB Opinion No. 25's intrinsic value method and, as such, generally recognize no
compensation cost for employee stock options. Accordingly, the adoption of SFAS No. 123(R)'s fair value method will have a significant impact on our result of operations, although it will have
no impact on our overall financial position. The impact of adoption of SFAS No. 123(R) cannot be predicted at this time because it will depend on levels of share-based payments granted in the
future. However, had we adopted SFAS No. 123(R) in prior periods, the impact of that standard would have approximated the impact of SFAS No. 123 as described in the disclosure of pro
forma net income and earnings per share

45

---



in
Note 1 to our consolidated financial statements. SFAS No. 123(R) also requires the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing
cash flow, rather than as an operating cash flow as required under current literature. This requirement will reduce net operating cash flows and increase net financing cash flows in periods after
adoption. While we cannot estimate what those amounts will be in the future (because they depend on, among other things, when employees exercise stock options), the amount of operating cash flows
recognized in prior periods for such excess tax deductions were $2,590,000 in 2002 and $0 in both 2003 and 2004.

Off-Balance Sheet Arrangements

There are no off-balance sheet transactions, arrangements or obligations (including contingent obligations) that have, or are reasonably likely to
have a material effect on our financial condition, changes in the financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources, except for the
lease of our Valencia facility. For additional information about the sale/leaseback of our Valencia facility, annual rent expense and scheduled rent payments see Note 15 of the notes to the
consolidated financial statements.

Year Ended December 31, 2004 Compared with Year Ended December 31, 2003

Net Revenue

Net revenue increased approximately $15.1 million, or 12.7%, to $134.8 million for 2004 from $119.7 million for 2003. Revenues for 2004 were
impacted primarily from an increase in accession volumes from approximately 2.5 million for 2003 to nearly 3.0 million for 2004, an increase of nearly 20.8%. Our strong
top-line results included a relatively large and concentrated amount of independent laboratory business. This independent laboratory business, which we believe to be temporary in nature,
began in third quarter 2004 and accounted for approximately 175,000 accessions that resulted in approximately $2.4 million of incremental revenue during 2004. Price per accession, excluding the
independent laboratory business, decreased by approximately 2.7% during 2004 as compared to 2003 due primarily to variations in the mix of higher and lower priced tests.

Cost of Services

Cost of services, which includes costs for laboratory operations, distribution services, and research and development, increased by $7.6 million, or 8.9%,
to $93.7 million for 2004 from $86.1 million for the comparable prior year period. As a percentage of revenue, cost of services decreased to 69.5% for 2004 from 72.0% for the comparable
prior year period. This cost increase is a result of higher accession volumes, which increased approximately 20.8% year-over-year, and resultant increases in costs for
reagents, laboratory labor, and distribution. In addition to accession volume growth, cost of services was impacted by approximately $1.2 million in costs incurred to relocate our laboratory
operations to our new facility in Valencia during the fourth quarter 2004. These relocation costs included costs related to the physical move and the required validation of laboratory equipment upon
arrival.

Selling, General and Administrative Expenses (Exclusive of Provision for Doubtful Accounts Charges and Stock-Based Compensation Charges)

Selling, general and administrative expenses (S,G&A) increased approximately $7.2 million or nearly 18.0% to $46.8 million for 2004 from
$39.6 million for the comparable prior year period. This year-over-year increase is a result of several factors that occurred during 2004 including relocation costs of
approximately $1.2 million recorded to S,G&A expenses; the disposal of approximately $500,000 of certain fixed assets, primarily IT equipment that will provide us with no future benefit;
increases of approximately $500,000 in certain legal and administrative expenses, including auditing fees related to compliance with Section 404 of the Sarbanes-Oxley Act; and approximately
$2.5 million of recurring facilities costs, including rent and depreciation of leasehold
improvements, related to the operation of the Valencia facility that were duplicative during the phased relocation of laboratory operations to our new Valencia facility that occurred during the fourth
quarter 2004. Other elements contributing to the elevated S,G&A costs during 2004 are increased expenses related to sales force enhancements, increased commissions due to revenue growth, and
significantly higher costs related to insurance policy renewals. As a percentage of revenue, selling, general and administrative expenses increased to 34.7% of revenue for 2004 as compared to 33.1%
for the comparable prior year period.

Provision for Doubtful Accounts Charges

Provision for doubtful accounts charges increased approximately $1.6 million or nearly 41.1% to $5.4 million for 2004 from $3.8 million for
the comparable prior year period. During the third quarter 2004 we increased our bad debt expense over historical rates by approximately $800,000. This increase was related to collection difficulties
experienced at one of our international clients, combined with lower than expected collections through the third quarter 2004 on account balances from 2003. Our bad debt performance, as measured as a
percentage of net revenue, was 4.0% for 2004 as compared to 3.2% for 2003.

Stock-Based Compensation Charges

Stock-based compensation charges increased from approximately $65,000 for 2003 to approximately $147,000 for 2004. The increase during 2004 is primarily due to a
charge related to the separation of our former chief financial officer on March 19, 2004 and a related modification of his stock option grant.

Facility Exit Costs

Our statement of operations also includes a separate line item for facility exit costs that are not included in costs of services or S,G&A. Total facility exit
costs were $2.3 million during 2004 with no comparable charge during 2003. These costs include fixed asset impairment charges related to various laboratory equipment, furniture and fixtures and
computer equipment that were replaced by new

47

---



furniture
and equipment at our new Valencia facility, and the remaining rental obligation on the closed Santa Monica laboratory.

Interest (Income) Expense, Net

Net interest income decreased from approximately $721,000 in 2003 to $408,000 in 2004. This reduction is primarily due to lower average daily investment balances
during the first quarter 2004 until we received the proceeds from our sale and leaseback agreement for our new Valencia facility on March 18, 2004. Additionally, we were only able to capitalize
a portion of our interest expense during 2004 in connection with the construction of our Valencia facility that was substantially completed during the third quarter 2004.

Provision for Income Taxes (Benefits)

Provision for income taxes (benefits) was approximately a $181,000 benefit for 2004 as compared to a $2.9 million benefit for the comparable prior year
period. Our effective tax rate was approximately 1.4% for 2004 as compared to a 31.2% for 2003. During 2004, we did not record any additional benefits for income taxes related to current operations.
However, we recorded an income tax benefit of $501,000 related to the successful resolution of federal and state tax audits, which were ongoing since the end of 2003. This benefit was partially offset
by a $320,000 income tax charge related to an increase in our valuation allowance against deferred tax assets that we recorded during the fourth quarter 2004 based upon our revised
short-term forecast and expected utilization of state net operating losses. We do not expect to record any additional benefits for income taxes should they be available. In the future, we
may adjust our estimates of the amount of valuation allowance needed and such adjustment would impact our provision for income taxes in the period of such change. If our loss narrows and we return to
profitability, the effective tax rate could fluctuate significantly depending on the exact nature of the operating results. Please see "Risk FactorOur effective tax rate may fluctuate and
we may not be able to fully realize all or a portion of our deferred tax assets."

Net Loss

We recorded a net loss of $13.0 million for 2004 as compared to a net loss of $6.4 million for the comparable prior year period. While net revenue
increased $15.1 million for 2004 as compared to 2003, our total costs and expenses increased by $18.7 million, including the $4.7 million of expenses that we incurred in
connection with relocation activities, and our income tax benefit decreased by $2.7 million. As a percentage of net revenue, a net loss of 9.6% was recorded for 2004 as compared to a net loss
of 5.3% for the comparable prior year period.

Year Ended December 31, 2003 Compared with Year Ended December 31, 2002

Net Revenue

Net revenue decreased approximately $20.5 million, or 14.6%, to $119.7 million for 2003 from $140.2 million for 2002. Revenues for 2003 were
impacted primarily due to a decline in accession volumes from approximately 2.9 million for 2002 to nearly 2.5 million for 2003, a decrease of more than 13%. This
year-over-year decline in accession volume resulted primarily from business loss due to our regulatory matters that were resolved in the third quarter of 2002. In addition,
with the February 2003 completion of Quest Diagnostics' acquisition of Unilab Corporation, previously our largest customer, we saw a significant decline in accessions from this customer. For
2003, Unilab contributed less than 3% of total net revenue as compared to approximately 10% in 2002. We also experienced a decline of approximately 1.4% in the aggregate average selling price for 2003
as compared to the comparable prior year period. This decline in aggregate average selling price was primarily due to the year-over-year reduction in independent laboratory
business. In addition, during

48

---



2002
approximately $2.3 million of net revenue was not recognized due to the lack of billing rights for Medicare and Medicaid services.

Cost of Services

Cost of services, which includes costs for laboratory operations, distribution services, and research and development, decreased by $18.3 million, or
17.5%, to $86.1 million for 2003 from $104.4 million for the comparable prior year period. This decrease is a result of lower accession volumes, which declined approximately 13%
year-over-year, and resultant reductions in costs for reagents and royalties, laboratory labor, and distribution. In addition, we were able to decrease our outsourced testing
costs by approximately $3.7 million for 2003 as compared to the comparable prior year period. This decrease was a result of the reinstatement of tests performed by the company after hiring,
training, and certifying additional California licensed personnel in the second half of 2002. As a percentage of revenue, costs of services decreased to 72.0% for 2003 from 74.5% for the comparable
prior year period.

Selling, General and Administrative Expenses (Exclusive of Provision for Doubtful Accounts Charges and Stock-Based Compensation Charges)

Selling, general and administrative expenses (S,G&A) decreased $5.8 million or 12.6% to $39.6 million for 2003 from $45.4 million for the
comparable prior year period. This decrease is a result of continued expense management and includes the benefit of an approximately $0.6 million reduction in depreciation as we reached full
depreciation on certain assets combined with a reduction in certain sales costs that declined commensurate with revenues. This decrease in current year expenses is partially offset by nearly
$2.0 million of one-time charges for legal settlement costs, primarily for the Bayer and Chiron agreements announced on August 15, 2003, and charges for the Valencia
facility, while the year ended December 30, 2002, S,G&A included approximately $0.5 million of various one-time costs. As a percentage of revenue, selling, general and
administrative expenses increased to 33.1% of revenue for 2003 as compared to 32.4% for the comparable prior year period.

Provision for Doubtful Accounts Charges

Provision for doubtful accounts charges decreased approximately $2.1 million or 34.8% to $3.8 million for 2003 from $5.9 million for the
comparable prior year period. The decline in bad debt expense recorded during 2003 was directly attributable to the reduction in revenues. Our bad debt performance, as measured as a percentage of net
revenue, was 3.2% for 2003 as compared to 4.2% for 2002.

Stock-Based Compensation Charges

Stock-based compensation charges increased from a net credit of approximately $28,000 for 2002 to a net charge of approximately $65,000 for 2003. The credit for
2002 was primarily due to forfeited stock options resulting from the reductions in workforce in June and September of 2002 that had the effect of reducing amortization expense.

Restructuring Charge

We recorded no restructuring charge for 2003, however $5.1 million of restructuring charges were incurred in 2002.

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

49

---



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 $468,000 in the third quarter of 2002. The charge was comprised of $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, we had a reduction in workforce focused primarily on the laboratory and recorded a restructuring charge of approximately $984,000. This charge was comprised of
approximately $508,000 of severance payments for employees whose positions were eliminated and $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
$3.9 million of severance and related obligations have been paid as of December 31, 2003. The remaining severance of $412,000 was paid in 2004.

Charge Related to Regulatory Matters

As a result of the actions taken in April 2002 by the federal Centers for Medicare and Medicaid Services (CMS), we recorded a charge of approximately
$2.3 million for 2002. Of this charge, approximately $1.5 million was reserved for Medicare and Medicaid services earned and billed but not collected for the period of
February 22, 2002, beginning of the sanction period, to March 31, 2002 and $800,000 was reserved for regulatory fines, inspection costs, and related legal expenses. We recorded no
additional charges related to regulatory matters for 2003.

Interest (Income) Expense, Net

Net interest income decreased from approximately $1.5 million to $721,000 from 2002 to 2003. This reduction directly reflects the cash utilized for capital
expenditures for the new Valencia facility construction and an information technology infrastructure upgrade for our existing facilities coupled with the significant interest rate declines experienced
in 2002 and 2003 resulting in lower interest yields on our investments.

Provision for Income Taxes (Benefits)

Provision for income taxes (benefits) was approximately a $2.9 million benefit for 2003 as compared to a $7.9 million benefit for the comparable
prior year period. This reduction is primarily due to the reduction in pretax losses. Our effective tax rate was approximately 31.2% for 2003 as compared to a 37.2% for 2002.

Net Loss

We recorded a net loss of $6.4 million for 2003 as compared to a net loss of $13.4 million for the comparable prior year period. This resulted in an
improvement of approximately $7.0 million or 52.5%. While net revenue declined $20.5 million for 2003 as compared to 2002, our total costs and expenses declined by $33.3 million.
A portion of the overall cost reduction was due to significant one-time components included in 2002, primarily $5.1 million of restructuring charges and $2.3 million of
charges related to our regulatory matters. Our income tax benefits declined by $5.0 million for 2003 as compared to 2002, a result of a lower pretax loss being recorded and a reduced effective
tax rate for the current year. As a percentage of net revenue, a net loss of 5.3% was recorded for 2003 as compared to a net loss of 9.6% for the comparable prior year period.

Liquidity and Capital Resources

Our cash and cash equivalents combined with short-term and long-term investments totaled $40.1 million as of December 31,
2004 as compared to $36.7 million as of
December 31, 2003. This $3.4 million increase is the result of our receipt of approximately $41.9 million in net proceeds on March 19, 2004 in connection with the sale and
leaseback agreement for our new Valencia facility that was partially offset by capital expenditures of approximately $26.8 million primarily related to the construction of our Valencia
facility, the repayment of long-term debt of approximately $5.2 million including accrued interest and negative cash flows from operations that resulted from the significant net
loss that we incurred during 2004.

During
the third quarter 2004, we substantially completed construction activities, relocated our administrative functions from Santa Monica to our Valencia facility and commenced making
lease payments to Lexington on September 1, 2004. During the fourth quarter 2004, we substantially completed the relocation of our laboratory functions to our Valencia facility. During 2004 we
incurred expenses of approximately $4.7 million to effect the relocation from Santa Monica to Valencia including the cost of planning and executing the physical move, disposals of certain
equipment that was replaced in our new facility, lease termination costs related to our former facilities in Santa Monica and bonuses paid to personnel who contributed to the successful relocation
process. During 2004 we received $41.9 million in proceeds, net of $1.6 million in deferred financing fees, from our sale and leaseback agreement for our Valencia facility. Receipt of
the $3.5 million balance of proceeds is expected during the first half of of 2005, contingent upon the completion of certain deliverables to Lexington, including completion of remaining
construction items and leasehold improvements. The $3.5 million balance of proceeds has been recorded as a receivable in our balance sheet as of December 31, 2004.

Operating
activities for 2004 used net cash of approximately $8.4 million. The net increase in accounts receivable and the net decrease in accrued liabilities combined to use cash
of approximately $5.9 million. The remaining use of cash from operating activities was driven by our $13.0 million net loss that was partially offset by $6.5 million of
depreciation and amortization and $2.4 million of losses on the disposal of property and equipment for 2004. Operating activities for 2003 provided net cash of approximately
$2.3 million. The effect of taxes were the primary contributor, generating cash of approximately $6.2 million, as $8.4 million was provided by income tax refunds partially offset
by approximately $2.2 million of deferred income taxes. The net decrease in the combined accounts payable and accrued liabilities used cash of approximately $2.3 million, primarily for
severance payments. The net loss of $6.4 million was offset by depreciation and amortization of $6.3 million.

Investing
activities for 2004 provided net cash of $3.8 million as we reported $43.5 million of proceeds, before impact of $1.6 million in deferred financing fees
(included as a financing activity), from our sale and leaseback agreement for our Valencia facility. These proceeds were partially offset by capital expenditures of $26.8 million primarily
related to the construction of our Valencia facility combined with approximately $13.0 million of net purchases of investments in marketable securities. Investing activities for 2003 used net
cash of $3.2 million as we invested $12.3 million to complete the Core and Shell phase of our Valencia facility, complete an information technology infrastructure upgrade for our
existing facilities, and improve certain core client electronic ordering and resulting applications. This investment was partially offset by $9.1 million of cash generated through the sale of
investments.

Net
cash used in financing activities was $4.6 million for 2004. During 2004 we repaid approximately $5.0 million of borrowings under our line of credit and paid
approximately $1.7 million in financing related expenses, including $1.6 million associated with the sale and leaseback of our Valencia facility. These uses of cash were partially offset
by the receipt of $2.1 million of proceeds in connection with the sale of stock to employees. Net cash provided by financing activities was $6.1 million for 2003. For 2003, net cash
provided by financing activities resulted from borrowings from

a
new line of credit with CIT Business Credit and the sale of stock to employees through the Employee Stock Purchase Plan and the exercise of stock options.

On
September 24, 2003, we entered into a $25 million asset-based credit agreement with CIT Business Credit (CIT), a unit of CIT Group Inc. The credit facility is
secured primarily by accounts receivable, with the availability of funds based on the outstanding balance of this asset. The original credit agreement provided us with an initial $15 million
line of credit. On August 13, 2004, we entered into an amendment to our agreement with CIT whereby CIT agreed to assist us in obtaining letters of credit in an aggregate amount of up to
$10.1 million. The aggregate amount of outstanding letters of credit reduces the amount that we can borrow against our $15.0 million line of credit. On September 14, 2004, CIT
assisted us in obtaining a $9.0 million irrevocable letter of credit with JPMorgan Chase Bank that names Lexington as the beneficiary. Lexington required us to post a security deposit in the
form of a letter of credit in connection with the lease agreement for our Valencia facility. The principal amount of borrowings was due three years from the closing date, the date the line of credit
matures. Interest is computed and payable monthly. Interest is based on the Chase Bank rate plus one-half percent (0.5%) per annum. On September 24, 2004, we paid down the entire
$5.2 million borrowed against the line of credit, including approximately $185,000 of accrued interest.

We
expect existing cash and cash equivalents, long-term investments and the balance of proceeds from the sale and leaseback arrangement will be sufficient to fund our
operations, meet our capital requirements to upgrade our IT infrastructure and support our current growth for the next year. 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. 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.

Contractual Obligations

In the table below, we set forth our contractual obligations as of December 31, 2004. Some of the figures we include in this table are based on
management's estimates and assumptions about these obligations, including their duration, the possibility of renewal, anticipated actions by third parties, and other factors. Because these estimates
and assumptions are necessarily subjective, the contractual obligations we will actually pay in future periods may vary from those reflected in the table.

Inflation

Inflation was not a material factor in either revenue or operating expenses during 2002, 2003, and 2004.

Subsequent Events

On February 4, 2005, Mr. Richard E. Belluzzo resigned from the Board of Directors. Mr. Belluzzo served as Chairman of the Board and also
served as Chairman of the Nominating/Corporate Governance Committee and the Compensation Committee of the Board of Directors. Mr. Belluzzo informed the Board that he resigned because of
recently increased external professional obligations. To the knowledge of our executive officers, Mr. Belluzzo's resignation was not due to any disagreement with our operating policies or
practices. On February 5, 2005, our Board of Directors appointed Mr. Richard K. Whitney, a current Director, to serve as Chairman.

On
February 13, 2005, we entered into a separation agreement with Douglas S. Harrington, M.D., as our chief executive officer and a member of our Board of Directors. The agreement
with Dr. Harrington provides that he will remain as our CEO and the Laboratory Director for 45 days, and that he will use his best efforts to complete a smooth executive transition and
ensure regulatory compliance, including any necessary securities filings and certifications, as well as laboratory licenses, inspections and accreditations. Under the agreement, Dr. Harrington
will also be available for an additional 30 days to assist us on business and regulatory matters as needed. Dr. Harrington also resigned from the Board of Directors in connection with
his departure.

The
agreement with Dr. Harrington provides that Dr. Harrington will continue to receive his current base salary during the 45 day transition. At the end of this
transition, Dr. Harrington will cease being an employee, and we will make a lump-sum payment in the amount of $275,000. Following the transition period, we will pay
Dr. Harrington severance payments totaling $840,000 (equivalent to two years of his current salary), payable bi-weekly. In the event that we require the services of
Dr. Harrington during the 30 days beyond the transition period, we will pay him $5,000 per day for his services. We will also reimburse Dr. Harrington for up to 18 months
of COBRA payments for health care coverage. We expect to record a charge for these payments to Dr. Harrington in the first quarter of 2005.

On
February 28, 2005, we entered into a twelve month consulting agreement, beginning March 1, 2005, with David R. Schreiber, a member of our Board of Directors, whereby
Mr. Schreiber will provide consulting services, including evaluating and implementing sales performance enhancement initiatives, identifying merger and acquisition opportunities, assessing and
reducing our expenditures and/or other services as are reasonably requested by the Board of Directors. We will pay Mr. Schreiber $27,083 per month for his consulting services, with the
exception of the months of March and April 2005, for which he will be paid $15,000 per month. Mr. Schreiber will also be eligible for a cash bonus of up to fifty percent of the total
compensation that he receives during the term of the agreement based on the Board of Director's assessment of Mr. Schreiber's achievement of performance objectives to be mutually established by
the Board and Mr. Schreiber.

53

---



Under
the consulting agreement, Mr. Schreiber was also granted an option to acquire 104,000 shares of our common stock, which vests in three installments: 25% on March 1,
2005; 25% on August 30, 2005; and 50% on November 30, 2005. The exercise price of the stock option grant was equal to the fair market value of the underlying shares at the close of
trading on March 1, 2005, and remains exercisable throughout the term of the agreement, and continuing for a period of one year following the last date on which Mr. Schreiber ceases to
be either a consultant, director or employee of the company. In the event the agreement is terminated by Mr. Schreiber for any reason, or is terminated by us for cause, the option grant will
stop vesting as of the date of such termination, whether or not Mr. Schreiber continues to serve as a director of the company, and shall remain exercisable for a period of 90 days from
the date of such termination.

The
consulting agreement with Mr. Schreiber can be terminated by either party at any time; however, in the event we terminate the agreement with Mr. Schreiber other than
for cause, Mr. Schreiber will be entitled to receive the remainder of the consulting service fees owed to him under the agreement on a pro rata basis, and the stock options granted to him will
continue to vest. In the event of a change of control or corporate transaction involving the company during the term of the agreement, Mr. Schreiber will receive a payment equivalent to six
months of consulting service fees, and the accelerated vesting of any unvested stock options granted to him in the agreement.

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

At any time, fluctuations in interest rates could affect 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, 2004, 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, 2004, we had cash and cash equivalents of $18.3 million, which had a weighted average yield of 2.42% per annum. At December 31, 2004, our
long-term investment balance of $21.8 million consisted of investments in U.S. government and agency obligations with maturity dates in excess of one year, a weighted average yield
per annum of 2.74% and an average of 30.9 months until maturity.

Specialty Laboratories, Inc. financial statements, schedules and supplementary data, as listed under Item 15, appear in a separate section of this Report
beginning on page F-1.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE.

None.

ITEM 9A. CONTROLS AND PROCEDURES.

(a)Evaluation of Disclosure Controls and Procedures.We maintain disclosure controls and procedures that are
designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the Securities and
Exchange Commission's rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to
allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no

54

---



matter
how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the
cost-benefit relationship of possible controls and procedures.

As
required by Rule 13a-15(b) of the Securities Exchange Act of 1934, we carried out an evaluation, under the supervision and with the participation of our management,
including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the quarter covered by
this report. Based on the foregoing, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level.

(b)Management's Report on Internal Control Over Financial Reporting.Internal control over financial reporting
refers to the process designed by, or under the supervision of, our Chief Executive Officer and Chief Financial Officer, and effected by our board of directors, management and other personnel, to
provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting
principles, and includes those policies and procedures that:



Internal
control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations. Internal control over
financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial
reporting also can be circumvented by collusion or improper management override. Because of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely
basis by internal control over financial reporting. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process
safeguards to reduce, though not eliminate, this risk. Management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company.

Management
has used the framework set forth in the report entitled "Internal ControlIntegrated Framework" published by the Committee of Sponsoring Organizations ("COSO") of
the Treadway Commission to evaluate the effectiveness of the Company's internal control over financial reporting. Management has concluded that the Company's internal control over financial reporting
was effective as of the end of the most recent fiscal year. Ernst & Young LLP has issued an attestation report on management's assessment of the Company's internal control over financial
reporting.

(c)Changes in Internal Controls.There have been no changes (including corrective actions with regard to
significant deficiencies or material weaknesses) in our internal control over financial reporting that occurred during the fourth fiscal quarter of the year ended December 31, 2004 identified
in connection with the evaluation referenced in paragraph (a) above that has materially affected, or is likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

Board
of Directors
Specialty Laboratories, Inc.

We
have audited management's assessment, included in the preceding Management's Report on Internal Control Over Financial Reporting, that Specialty Laboratories, Inc. (Specialty)
maintained
effective internal control over financial reporting as of December 31, 2004, based on criteria established inInternal ControlIntegrated
Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Specialty's management is responsible for maintaining effective
internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management's
assessment and an opinion on the effectiveness of Specialty's internal control over financial reporting based on our audits.

We
conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control
over financial reporting, evaluating management's assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered
necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A
company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of
financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures
that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide
reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and
expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely
detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because
of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future
periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In
our opinion, management's assessment that Specialty maintained effective internal control over financial reporting as of December 31, 2004, is fairly stated, in all material
respects, based on the COSO criteria. Also, in our opinion, Specialty maintained, in all material respects, effective internal control over financial reporting as of December 31, 2004, based on
the COSO criteria.

We
have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Specialty as of
December 31, 2003 and 2004, and the related consolidated statements of operation, shareholders' equity, and cash flows for each of the three years in the period ended December 31, 2004
of Specialty Laboratories, Inc. and our report dated March 9, 2005 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

Board
of Directors
Specialty Laboratories, Inc.

We
have audited the accompanying consolidated balance sheets of Specialty Laboratories, Inc. as of December 31, 2003 and 2004, and the related consolidated statements of
operations, shareholders' equity and cash flows for each of the three years in the period ended December 31, 2004. Our audits also include the financial statement schedule listed in the Index
at Item 15(a)(2). These consolidated financial statements and schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial
statements and schedule based on our audits.

We
conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our opinion.

In
our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Specialty
Laboratories, Inc. as of December 31, 2003 and 2004, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31,
2004, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial
statements taken as a whole, presents fairly in all material respects the information set forth therein.

We
also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of Specialty Laboratories, Inc.'s
internal control over financial reporting as of December 31, 2004, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission and our report dated March 9, 2005, expressed an unqualified opinion thereon.

Specialty Laboratories, Inc.
Notes to Consolidated Financial Statements

December 31, 2004

1. Summary of Significant Accounting Policies

Description of Business

Specialty Laboratories, Inc. is a corporation that provides specialized laboratory-testing services to physicians, hospitals, and independent laboratories
throughout the United States. Our 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.

Reclassifications

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

Cash and Cash Equivalents

We consider highly liquid debt securities with original maturities of 90 days or less at acquisition 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 representing the difference between our standard charges and direct billings to
third-party payor programs, including Medicare and Medicaid fee schedules. The allowance for doubtful accounts represents an estimate of the difference between amounts currently due from our
hospitals, independent laboratories, and physician specialists and other customers and the receipts on such account balances estimated based on historical trends and current factors.

Inventory

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

F-6

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5 yearsLeasehold improvements

The lesser of life (7 to 20 years) of asset or lease term


Goodwill and Intangible Assets

We allocate 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, which are amortized evenly over periods of 10 and 4.5 years, respectively. Effective January 1, 2002, we ceased
amortization of goodwill in accordance with the provisions of Statement of Financial Accounting Standards (SFAS) No. 142, "Goodwill and Other Intangible
Assets". Prior to 2002, we amortized goodwill over 20 years. We performed the required impairment tests of goodwill in 2002, 2003 and 2004 and no impairment was
identified in these periods.

Under
SFAS No. 142, intangible assets continue to be amortized over their useful lives. The estimated amortization expense for intangible assets will be $289,000 for 2005,
$225,000 for 2006, $193,000 for the next four years, and $32,000 for the final year.

Long-lived Asset Impairment

We review long-lived assets for impairment when events or changes in business conditions indicate that their carrying value may not be recovered. We
consider assets to be impaired and write 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. As
a result of our relocation to new
state-of-the-art laboratory facilities during the 2004 fourth quarter, various long-lived assets recorded as property and equipment were replaced,
abandoned or otherwise impaired. We recorded a charge in the amount of $1,838,000 included in facility exit costs to dispose of these assets. See "Note 3Facility Exit Costs." We
have determined that no long-lived assets, other than the aforementioned property and equipment, are impaired at December 31, 2004.

Revenue Recognition

We recognize revenue as services are rendered upon completion of the testing process for a specific customer order for which we have 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. 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 receivable amounts based on final
settlements with the third-party payor programs are recorded upon settlement. Such adjustments were not material to our net loss in 2002, 2003 and 2004. In 2002, 2003 and 2004, combined third-party
payor programs, including Medicare and Medicaid, comprised 6.6%, 8.3%, and 9.3%, of our net revenue, respectively.

F-8

---



Research and Development Expenditures

Research and development expenditures are expensed as incurred. The amounts charged to research and development expense were $2,215,000, $1,648,000 and $1,315,000
in 2002, 2003, and 2004, respectively.

Concentrations of Credit Risk

Our concentration of credit risk with respect to accounts receivable is limited due to the large number of payors comprising our customer base which are spread
across the United States. In addition, we maintain allowances for potential credit losses and such losses have been within management's expectations. We routinely assess the financial strength of our
customers and generally do not require collateral.

Unilab
Corporation accounted for approximately 10% of our net revenue in 2002. In 2003 and 2004, 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. We routinely estimate
amounts to be recovered from third-party payors. Actual results could differ from those estimates.

Stock-Based Compensation

At December 31, 2004, we had one stock-based compensation plan, which is described more fully in Note 13. We account for the plan 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 stock at the date
of grant over the amount an employee must pay to acquire the stock. We have adopted the disclosure provisions required by SFAS No. 148, "Accounting for Stock-Based
CompensationTransition and Disclosure".

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

These
pro forma amounts may not be representative of 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:

Year ended December 312002

For
sales of our 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.

On
December 16, 2004, the Financial Accounting Standards Board (FASB) issued SFAS No. 123 (revised 2004), Share-Based Payment, which is a revision of SFAS No. 123, Accounting for Stock-Based
Compensation. SFAS No. 123(R) supersedes APB Opinion No. 25,Accounting for Stock
Issued to Employees, and amends SFAS No. 95,Statement of Cash Flows. Generally, the approach in SFAS No. 123(R)
is similar to the approach described in SFAS No. 123. However, SFAS No. 123(R)requiresall share-based payments to employees, including
grants of employee stock options, to be recognized in

F-10

---



the
income statement based on their fair values. Pro forma disclosure is no longer an alternative. SFAS No. 123(R) must be adopted no later than July 1, 2005 for calendar quarter
companies. Early adoption will be permitted in periods in which financial statements have not yet been issued. We will utilize the modified prospective method, recognizing compensation cost for
share-based awards to employees based on their grant-date fair values from the beginning of the year in which the recognition provisions are first applied as if the fair value-based method
had been used to account for all employee awards. Under this transition approach, compensation cost will be recognized for all awards granted, modified or settled after the date of adoption as well as
to any awards that were not fully vested as of that date. Any adjustments to recognize share-based liabilities at fair value from the beginning of the year through the date of adoption will be
recognized as a cumulative effect of a change in accounting principle. We expect to adopt SFAS No. 123(R) on July 1, 2005.

The
adoption of SFAS No. 123(R)'s fair value method will have a significant impact on our results of operations, although it will have no impact on our overall financial position.
The impact of adoption of SFAS No. 123(R) cannot be predicted at this time because it will depend on levels of share-based payments granted in the future. However, had we adopted SFAS
No. 123(R) in prior periods, the impact of that standard would have approximated the impact of SFAS No. 123 as described in the disclosure of pro forma net income and earnings per share
set forth above in this Note. SFAS No. 123(R) also requires the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing cash flow, rather than as an
operating cash flow as required under current literature. This requirement will reduce net operating cash flows and increase net financing cash flows in periods after adoption. While we cannot
estimate what those amounts will be in the future (because they depend on, among other things, when employees exercise stock options), the amount of operating cash flows recognized in prior periods
for such excess tax deductions were $2,590,000 in 2002 and $0 in both 2003 and 2004.

Income Taxes

We utilize the liability method of accounting for income taxes as set forth in SFAS 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. In the preparation of our
consolidated financial statements, we are required to estimate income taxes in each of the jurisdictions in which we operate, including estimating both actual current tax exposure and assessing
temporary differences resulting from differing treatment of items for tax and accounting purposes. Assessment of actual current tax exposure includes assessing tax strategies, the status of tax audits
and open audit periods with the taxing authorities. To the extent that we have deferred tax assets, we must assess the likelihood that our deferred tax assets will be recovered from future operations
and tax strategies that we employ and to the extent that we believe that recovery is not likely, we must establish a valuation allowance. As of December 31, 2004 we have established a valuation
allowance of $7,211,000 against our deferred tax assets as we believe it is not more likely than not that such assets will be realized. In the future, we may adjust our estimates of the amount of
valuation allowance needed and such adjustment would impact our provision for income taxes in the period of such change.

F-11

Fair Value of Financial Instruments

Our financial instruments consist mainly of cash, cash equivalents, short-term investments, long-term investments, accounts receivable,
accounts payable and borrowings under its bank credit facility. The fair value of substantially all financial instruments approximates their carrying values in the aggregate due to the
short-term nature of these instruments. The interest rates on borrowings under our bank credit facilities are adjusted periodically to market rates, as discussed in Note 10.

Earnings Per Share

Basic loss per share is computed by dividing net loss by the weighted average number of common shares outstanding. Dilutive earnings per share is 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 we reported a net loss in 2002, 2003 and 2004, these potentially dilutive common shares were excluded from the diluted loss per share calculation
because they were anti-dilutive.

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

2. Sale and Leaseback of Building

On February 11, 2004, we entered into an agreement for the sale and leaseback of its Valencia, California facility with Lexington Corporate Properties
Trust (Lexington), a real estate investment trust. Lexington agreed to purchase the existing facility for $47.0 million. The closing of the sale was completed on March 18, 2004 and we
received approximately $41.9 million in proceeds, net of $1.6 million of financing related expenses through December 31, 2004. Receipt of the remaining $3.5 million balance
of proceeds (included in receivable from sale of property) is contingent upon the completion of certain deliverables to Lexington. During the third quarter 2004, we relocated our administrative
functions from Santa Monica, California to our Valencia facility and commenced making lease payments to Lexington on September 1, 2004. During the fourth quarter 2004, we relocated
substantially all of our laboratory operations functions from Santa Monica to our Valencia facility.

For
the first five years, lease payments will be fixed at an annual rate of approximately $3.5 million and will be adjusted every five years. Lease payments for years 6 through 10
will be the amount necessary to fully amortize the total project cost over 15 years at an interest rate equal to the sum of the then interpolated 15-year U.S. Treasury Bond rate
plus 75 basis points. Payments will be increased 10% for years 11 through 15 with an additional 10% increase scheduled for years 16 through 20. The primary term for the lease is twenty years. There
are three options to extend the term of the lease: two renewal options of five years each and a third renewal option for four years and six months.

Based
on an interpolated 15-year Treasury Rate of 4.37% at December 31, 2004, the estimated minimum lease payments under the terms of the related lease agreement are
reflected in the table below. Actual lease payments for years 6 through 20 will be determined at least sixty days prior to the first day of the sixth lease year. These estimates of minimum lease
payments are subject to future changes in the interpolated 15-year Treasury Rate, which has increased slightly since the sale and leaseback transaction was completed, and which can be
expected to vary further prior to and during years 6 through 20 of the lease.

|--------------------------- |  | ----------------------
|
|
|Operating lease obligations |  | $                     

The
lease payments are being accounted for under FASB Technical Bulletin 85-3,Accounting for Operating Leases with Scheduled Rent
Increases, which requires minimum lease payments with scheduled rent increases to be accounted for on a straight-line basis over the lease term. Rent expense for
the facility will be approximately $4.6 million per year.

3. Facility Exit Costs

In accordance with the provisions of SFAS No. 146,Accounting for Costs Associated with Exit or Disposal
Activities, and in connection with the relocation to its new Valencia facility during the fourth quarter 2004, we recorded a $2,309,000 charge related to exiting our existing
facilities in Santa Monica. This charge is included in facility exit costs in our statement of operations for the year ended December 31, 2004. The components of the facility exit costs charge
are reflected in the table below.

Lease termination costs

471,000Fixed asset impairment charge (Note 1Long-lived Asset Impairment)

$
2,309,000


Lease
termination costs represent the amount of lease rental payments that will be paid through June 2005, the end of our current lease contracts for facilities located in Santa
Monica. Fixed asset impairment charges represent the net book carrying value of various laboratory equipment, furniture and fixtures and computer equipment that were replaced by new furniture and
equipment at our Valencia facility. The decision to replace this property and equipment was made in connection with relocation activities that occurred during the fourth quarter 2004. Consequently, we
recorded a charge during the fourth quarter 2004 to reflect the impairment of this property and equipment located at our former facilities in Santa Monica.

4. Charge Related to Regulatory Matters

By letter dated April 12, 2002, the federal Centers for Medicare & Medicaid Services (CMS) notified us that it concluded our February 2002
response to deficiencies detected in the June and October 2001 inspections conducted by the California Department of Health Services (CDHS) 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, canceling our approval to receive Medicare and Medicaid payments for services performed on or after
February 22, 2002, 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.

On
April 26, 2002, we filed supplemental documentation supporting our compliance with the applicable requirements with CDHS and CMS. 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 imposed sanctions of a civil money penalty of $344,000, plus $20,430 for the cost of
conducting their investigations, and imposed onsite monitoring for three years, including unannounced inspections.

On
July 17, 2002, CMS notified us that it had deemed us in compliance with all condition level requirements of CLIA and, that our ability to bill Medicare and Medicaid for our
testing services had been reinstated, effective June 19, 2002, and that all actions against our CLIA certificate had been rescinded. We withdrew the appeal of the sanctions we had filed with
CMS on April 17, 2002 and paid a monetary fine of $351,000.

We
recorded a charge in the first quarter of 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 the second quarter of 2002, we 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, we 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 our 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.

5. Restructuring Charge

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
our company. In connection with the restructuring effort, a charge of approximately $3,598,000 was recorded in the second quarter of 2002. The charge was comprised of 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 the
clinical trials department. A charge of approximately $468,000 was recorded in the third quarter of 2002. The charge was comprised of $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 our 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.

Gross
realized gains and losses were immaterial in 2003 and 2004. Scheduled maturities of U.S. government and agency investments held at December 31, 2004 are $12,916,000 in 2006
and $8,906,000 in 2007. The unrealized losses on our investments in U.S. government and agency obligations were

caused
by interest rate increases. The contractual terms of these investments do not permit the issuer to settle the securities at a price less than the amortized cost of the investment. Because we
have the ability and intent to hold these investments until a recovery of fair value, which may be maturity, we do not consider these investments to be other-than-temporarily
impaired at December 31, 2004. Also, the disclosures required by EITF 03-1, "The Meaning of Other-Than-Temporary and its Application to Certain Investments,"
have not been included because our unrealized losses are immaterial at December 31, 2004.

8. Write-Down of Unused Facility Costs

In 1997, we leased a building in Memphis, Tennessee, for a potential geographical expansion of its operations. Subsequently, in June 1999, our 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, we 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, 2004 is $196,000. We do not anticipate
any future adjustments to the accrual.

10. Long-Term Debt

On September 24, 2003, we entered into a $25 million asset-based credit agreement with CIT Business Credit (CIT), a unit of CIT Group Inc.
The credit facility is secured primarily by accounts receivable, with the availability of funds based on the outstanding balance of this asset. The original credit agreement provided us with an
initial $15 million line of credit. On August 13, 2004, we entered into an amendment to its agreement with CIT whereby CIT agreed to assist us in obtaining letters of credit in an
aggregate amount of up to $10.1 million. The aggregate amount of outstanding letters of credit reduces the amount that we can borrow against its $15.0 million line of credit. On
September 14, 2004, CIT assisted us in obtaining a $9.0 million irrevocable letter of credit with JPMorgan Chase Bank in satisfaction of a requirement in our lease agreement for our
Valencia facility (Note 15Commitments and Contingencies). The principal amount of borrowings was due three years from the closing date, the date the line of credit matures.
Interest is computed and payable monthly. Interest is based on the Chase Bank rate plus one-half percent (0.5%) per annum. As of December 31, 2003, we had borrowed $5,019,000
against the line of credit. On September 24, 2004, we paid down the entire $5.2 million borrowed against the line of credit, including approximately $185,000 of accrued interest.

Interest
expense for 2002, 2003 and 2004 was $209,000, $114,000 and $352,000 gross, respectively. During 2003 and 2004, we capitalized approximately $100,000 and $169,000, respectively,
of interest related to the Valencia construction.

11. Profit Sharing Plan401(k)

We maintain 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. We will match the employee's contribution at 50 cents per dollar up to 6% of the
employee's salary. Matching contributions by us to the 401(k) Plan amounted to $735,000, $621,000 and $648,000 in 2002, 2003 and 2004, respectively. Profit sharing contributions to the 401(k) Plan are
discretionary. No discretionary contributions were made during 2002, 2003 and 2004.

12. Deferred Compensation Program

We have a non-qualified deferred compensation program (the Program) for certain executives. Under the Program, employee-designated deferrals of salary
are withheld by us. 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, we purchase life insurance policies on each of the participating executives with our company named as beneficiary of the
policies.

Deferred
compensation, including gains and losses on phantom investments, amounted to $1,602,000 and $1,371,000 at December 31, 2003 and 2004, respectively, and is classified in
long-term liabilities. The cash surrender value of the life insurance policies, which amounted to $2,131,000 and $2,336,000 at December 31, 2003 and 2004, respectively, is recorded
in other assets.

13. Shareholders' Equity

Stock Option Plans

During 1999, our 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 our common stock to certain of our employees and outside directors. Outstanding stock options previously granted were effectively cancelled and replaced with new
options under the 1999 plan.

On
September 5, 2000, our Board of Directors adopted, and on June 3, 2004 the shareholders approved, the 2000 Stock Incentive Plan (the 2000 Plan). The 2000 Plan became
effective on the date the underwriting agreement for the initial public offering was signed. Under the 2000 Plan, 6,620,429 shares of our common stock have been authorized for issuance, including
shares currently reserved under the 1999 Plan.

The
majority of grants under the Plan 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

F-18

---



compensation
to acquire an option grant to acquire shares of our 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 our
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. For more information regarding our stock option plans, see our 2004 Proxy Statement for Annual Meeting of Shareholders.

The
weighted average remaining contractual life of outstanding options was 7.9 and 7.2 years at December 31, 2003 and 2004, respectively.

Stock-Based Compensation

In connection with the sales of common stock to certain employees and the granting of stock options to certain employees and our outside directors on
February 5, 1999, the amount of related compensation to be recognized was determined by us to be the difference between the stock purchase or option exercise price and the fair value of our
common stock at that date. For the common stock sales and the stock options that were vested as of their date of grant, the related compensation was expensed in full as of February 5, 1999. For
the stock options that 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 resulting from amortization of deferred stock-based compensation totaled $(28,000), $65,000 and $13,000 for the years ended December 31, 2002,
2003, and 2004, respectively.

Stock-based
compensation charges also included $134,000 for the excess of the intrinsic value on the separation date over the original intrinsic value at the stock option grant date
related to the March 19, 2004 resignation of our senior vice president and chief financial officer and our agreement to modify his stock option agreement. We agreed to extend the period in
which he can exercise his vested stock options in exchange for the provision of certain nonsubstantive services through the filing of our Form 10-Q for the 2004 first quarter.

Stock Purchase Plan

On September 5, 2000, our 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 our 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 our 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 2003 and 2004, 94,503 and 95,897 shares, respectively, had been purchased under the Purchase Plan.

14. 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.

For
2004, we did not record any additional benefits for income taxes due to the size of the deferred tax assets (DTA's) previously recognized on our consolidated balance sheet through
December 31, 2004. During the fourth quarter of 2004, we recorded a $320,000 increase in the valuation allowance for deferred tax assets recognized during 2003 and prior periods. We reported
$5,864,000 of net DTA's (current and long-term) in the December 31, 2004 balance sheet, with approximately $15,187,000 of this amount related to federal and state net operating loss
carryforwards (NOL's). The future realization of the NOL's is dependent on our ability to generate approximately $33.5 million of federal and $42.8 million of state ordinary income in
future years. Our inability to generate the necessary ordinary income, could have a material adverse effect on our results of operations in future years.

The
federal NOL's begin expiring in 2024 and the state NOL's begin expiring in 2014. SFAS No. 109, "Accounting for Income Taxes",
requires that deferred tax assets be reduced by a valuation allowance if it is more likely than not that some portion or all of the DTA's will not be realized. During 2004, we increased our valuation
reserve to $7,211,000 from zero reported as of December 31, 2003. The increase in the 2004 valuation reserve is principally due to continued operating losses, including tax benefits recognized
on exercise of employee stock options, and our assessment that it is more likely than not that a portion of our DTA's will not be realized. In making this determination, we considered all available
positive and negative evidence and made certain assumptions. This included, among other

F-21

---



things,
the overall business environment, our historical earnings, including our significant pretax losses incurred during the last three years, and our outlook for future years. We performed this
analysis as of December 31, 2004 and determined that there was sufficient positive evidence to conclude that it is more likely than not that our recorded net DTA's, net of the recorded
valuation allowance, will be realized. We will assess the need for additional DTA valuation allowances on an ongoing basis considering factors such as those mentioned above as well as other relevant
criteria. Changes in our assumptions may affect our assessment and require that we establish valuation allowances for some portion or all of the remaining DTA's. Such changes may have a material
adverse impact on our consolidated financial statements.

Our
effective tax rate is based on expected income, statutory tax rates and tax planning opportunities available to us in the various jurisdictions in which we operate. Significant
management estimates and judgments are required in determining the effective tax rate. We are routinely under examination by federal, state or local authorities regarding the timing and amount of
deductions, nexus of income among various tax jurisdictions and compliance with federal, state and local tax laws. Tax assessments related to these audits may not arise until several years after tax
returns have been filed.

F-22

---



Although
predicting the outcome of such tax assessments involves uncertainty, we believe that the recorded tax liabilities appropriately account for the analysis of probable outcomes, including
interest and other potential obligations. The tax liabilities are adjusted in light of changing facts and circumstances, such as the progress of audits, case law and emerging legislation and such
adjustments are included in the effective tax rate.

During
2003, a federal income tax examination related to the years ended December 31, 2000, 2001 and 2002 commenced. In addition, during 2003, a California income tax examination
related to the years ended December 31, 1999 and 2000 commenced. During 2004, the federal and state tax examinations were concluded and resulted in proposed tax adjustments, including estimated
accrued interest expense. As a result, in September 2004 we recorded an income tax benefit of $501,000 related to the successful resolution of the federal and state tax examinations. Our
recorded liability at December 31, 2004 approximates the estimated impact of these proposed tax adjustments.

15. Commitments and Contingencies

Commitments

We lease certain facilities and equipment under operating leases. Certain leases contain renewal and purchase options. Rental expense was approximately
$3,591,000, $3,277,000 and $4,951,000 for 2002, 2003 and 2004, respectively.

Future
minimum lease payments under noncancelable operating leases with initial terms of one year or more (including the estimated minimum lease payments under our lease for our Valencia
facility as discussed in Note 2) are as follows:

In
May 2002, we 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, we 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, we will pay the base salary for a two-year period and a bonus for a one-year period subsequent
to his severance.

In
September and December 2003 and in April 2004, we entered into employment agreements with nine current executive officers. The agreements with three of the executives,
which provide in the

F-23

---



aggregate
for annual base salaries of approximately $832,000 provide that if these three employees are terminated for other than cause or they resign for good reason, we will pay their salaries for
twelve months subsequent to their termination and will make a lump sum payment for an amount equivalent to the payments for twelve months of health benefits under COBRA. For the remaining six
executive officers, if any of these employees are terminated for other than cause or they resign for good reason, we will pay their salaries for nine months subsequent to their termination and a lump
sum payment for an amount equivalent to the payments for nine months of health benefits under COBRA. The aggregate for the nine months of base salaries is approximately $893,000. If any of these
executives are terminated for cause or voluntarily resign, no further payments are due to them other than accrued but unpaid salary and vacation time as of the date of termination.

In
January 2003, we established a $680,000 irrevocable Letter of Credit for Federal Insurance Company, our workers' compensation insurance provider for 2003. The Letter of Credit
was increased to $1,030,000 effective January 2004 and further increased to $1,330,000 effective January 2005. We elected to utilize a deductible program for 2003 and 2004 for which
Federal Insurance Company required a security deposit in the form of a Letter of Credit.

On
September 14, 2004, we established a $9.0 million irrevocable letter of credit with JPMorgan Chase Bank that names Lexington Corporate Properties Trust (Lexington), our
landlord for our Valencia facility, as the beneficiary. The Valencia facility lease requires us to post a security deposit in the form of a letter of credit in connection with the lease agreement for
its Valencia facility.

Contingencies

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, and subsequently consolidated as "In re Specialty Laboratories Securities Litigation".
The lawsuit purported 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 alleged 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 alleged, 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
sought compensatory damages, including interest, costs and expenses, attorneys' fees, and other relief. Plaintiffs filed several amended complaints, and we in turn filed motions to dismiss these
complaints. The court ruled on these motions, dismissing some claims and not dismissing others, and allowed plaintiffs to proceed with their claims against us and several current and former officers
and directors for alleged violations of both the Securities Act of 1933 and the Securities Exchange Act of 1934. We believe that the claims against us and our current and former officers and directors
were without merit. On June 14, 2004, we announced an agreement in principle to settle the consolidated lawsuits for $12 million, to be paid fully by our insurance carriers. On
December 22, 2004, the court entered a final order approving the settlement and providing for notice to shareholders. As the settlement and defense costs were paid by our insurance carriers, we
do not anticipate any costs associated with the defense or settlement of the claims to have a material impact on our finances.

Specialty
Laboratories Asia Pte. Ltd., a Singapore corporation, ("SLA"), is 60% owned by our wholly-owned subsidiary, Specialty Laboratories International Ltd., a British
Virgin Islands corporation ("SLIL"). 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 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. No action has been brought against Specialty Laboratories, Inc. and we cannot provide an estimate of any loss or
potential loss in connection with this matter.

In
December 2003, we were served with an action in which we are named as a defendant, together with certain of our former officers, SLIL, and multiple other parties located in
Singapore and India, in a lawsuit brought in the High Court of the Republic of Singapore by Dragon Investment Company ("Dragon"), one of the shareholders in SLA. Dragon has also brought the lawsuit in
the name of SLA
as a derivative action. The lawsuit alleges, among other things, that SLA and Dragon suffered damages as a result of the winding up of the affairs of SLA and disposition of its assets. The lawsuit
also alleges that certain of the defendants breached certain written agreements to allow Dragon to acquire more shares of SLA, that certain of our former officers conspired to run down and dissipate
the assets of SLA, and that they fraudulently concealed their actions from Dragon and the other minority shareholder of SLA. We have provided notice to the applicable insurance carriers. While we
believe that we have insurance applicable to the defense of the lawsuits, and continue to work with the relavent insurance carriers on the coverge issue, such carriers have not yet acknowledged
coverage of the matter. Because our insurance carriers have not yet acknowledged coverage in this matter, and plaintiffs have not provided specific range or amount of damages sought from us, we are
unable to provide any estimates of any loss or potential loss in this matter.

From
time to time we are subject to other claims arising in the ordinary course of business. We intend to defend vigorously any such litigation that may arise and to assert all available
defenses that would be available to us. Based on current information, we believe any ultimate liability that may arise from these claims would not materially affect our consolidated financial
position, results of operations or cash flows. However, our evaluation of the likely impact of these actions could change in the future and an unfavorable outcome, depending upon the amount and
timing, could have a material effect on our results of operations or cash flows of a future period.

16. Subsequent Event

On February 13, 2005, we entered into a separation agreement with Douglas S. Harrington, M.D., as our chief executive officer and a member of our Board of
Directors. The agreement with Dr. Harrington provides that he will remain as our CEO and the Laboratory Director for 45 days, and that he will use his best efforts to complete a smooth
executive transition and ensure regulatory compliance, including any necessary securities filings and certifications, as well as laboratory licenses, inspections and accreditations. Under the
agreement, Dr. Harrington will also be available for an

F-25

---



additional
30 days to assist us on business and regulatory matters as needed. Dr. Harrington also resigned from the Board of Directors in connection with his departure.

The
agreement with Dr. Harrington provides that Dr. Harrington will continue to receive his current base salary during the 45 day transition. At the end of this
transition, Dr. Harrington will cease being an employee, and we will make a lump-sum payment in the amount of $275,000. Following the transition period, we will pay
Dr. Harrington severance payments totaling $840,000 (equivalent to two years of his current salary), payable bi-weekly. In the event that we require the services of
Dr. Harrington during the 30 days beyond the transition period, we will pay him $5,000 per day for his services. We will also reimburse Dr. Harrington for up to 18 months
of COBRA payments for health care coverage.
