PART I

ITEM 1. BUSINESS

Overview

We develop, manufacture and sell proprietary biological testing technologies and products with applications throughout the life sciences and diagnostic industries. These industries depend on a broad range of tests, called bioassays, to perform diagnostic tests, discover and develop new drugs and identify genes. Our xMAP^® (Multi-Analyte Profiling) technology, an open architecture, multiplexing technology, allows simultaneous analysis of up to 100 bioassays from a small sample volume, typically a single drop of fluid, by reading biological tests on the surface of microscopic polystyrene beads called microspheres. xMAP technology combines this miniaturized liquid array bioassay capability with small lasers, digital signal processors and proprietary software to create a system offering advantages in speed, precision, flexibility and cost. Our xMAP technology is currently being used within various segments of the life sciences industry which includes the fields of drug discovery and development, clinical diagnostics, genetic analysis, bio-defense, protein analysis and biomedical research. Our business is currently organized into two reportable segments: the technology segment and the assay segment. Our products are described below under “Products.”

The technology segment was initially built around strategic partnerships. As of December 31, 2008, we had approximately 60 strategic partners, 35 of which have developed reagent-based products utilizing our technology. Luminex and these partners have sold over 5,800 xMAP-based instruments in laboratories worldwide as of December 31, 2008. We license our xMAP technology to our partners, who then develop products that incorporate the xMAP technology into products that they sell to the end-user. We also develop and manufacture the proprietary xMAP laboratory instrumentation and the proprietary xMAP microspheres and sell these products to our partners. When our partners sell xMAP-based reagent consumable products or xMAP-based testing services, which run on the xMAP instrumentation, to the end-user customer, such as testing laboratories, we obtain a royalty on the sales from the partner. Luminex was founded on this model, and our success to date has been due to this model.

The assay segment consists of Luminex Bioscience Group, or LBG, and Luminex Molecular Diagnostics, or LMD. This segment is primarily involved in the development and sale of assays utilizing xMAP technology on our installed base of systems. The Assay Segment augments our partnership model with a distribution model, designed to take advantage of our increasing installed base of xMAP-based instrumentation. LBG introduced our first two assay products in late 2006.

LMD, which we created upon our acquisition of Tm Bioscience in March 2007, is focused on multiplexed applications for the human molecular clinical diagnostics market. Tm Bioscience focused on the three segments of the genetic testing market for which it was developing products: human genetics, personalized medicine and infectious disease. Tm Bioscience had established a solid position in the marketplace with their product development and FDA-compliant manufacturing capabilities. We substantially completed the integration of Tm Bioscience during 2007, and we believe the combined Company is in a position to take advantage of the complementary strengths of both companies in molecular diagnostics. In January 2008, the Assay Segment launched xTAG^TM Respiratory Viral Panel (RVP), which is the first Food and Drug Administration (FDA)-cleared assay to simultaneously detect and identify 12 viruses and viral subtypes that together are responsible for more than 85 percent of respiratory viral infections.

We have established a leading position in several segments of the life sciences industry by developing and delivering products that meet customer and partner needs in specific market segments, including multiplexing, accuracy, precision, sensitivity, specificity, reduction of labor and ability to test for proteins and nucleic acids. These needs are addressed by our proprietary technology, xMAP Technology, which allows the end-user in a laboratory to perform biological testing in a multiplexed format. Multiplexing allows for many different laboratory results to be generated from one sample at one time. This is important because our end-user customers and partners, which include laboratory professionals performing research, clinical laboratories performing tests on patients as ordered by a physician and other laboratories, have a fundamental need to perform high quality testing as efficiently as possible. Until the availability of multiplexing technology such as xMAP, the laboratory professional had to perform one test on one sample in a sequential manner, and if additional testing was required on that sample, a second procedure would be performed to generate the second result, and so on until all the necessary tests were performed. By using xMAP technology, these end-users have the opportunity to become more efficient by generating multiple simultaneous results per sample. We believe that this technology may also offer advantages in other industries, such as food safety/animal health, newborn screening and bio-defense/bio-threat markets. Using the products Luminex has available today, up to 100 simultaneous analyte results can be generated from a single sample. With products we are currently developing and that are planned for market release in 2009, the capacity of potential simultaneous analytes will increase significantly up to 500 analyte results, and provide us with the ability to address unmet customer and partner needs in existing and new market segments.

Industry Background

The life sciences industry uses bioassays to detect the presence and characteristics of certain biochemicals, proteins or nucleic acids in a sample. Drug discovery, genetic analysis, pharmacogenomics, clinical diagnostics and general biomedical research all use bioassays. For example, bioassays can be used to:

• measure the presence and quantity of substances such as infectious agents, antigens for histocompatibility, hormones, cancer markers and other proteins in a patient’s blood, other body fluid or tissue to assist physicians in diagnosing, treating or monitoring disease conditions;

• detect genetic variations, such as single nucleotide polymorphisms or genetic mutations present in inherited diseases;

• measure the response to a compound or dosage by measuring cellular activity for drug discovery and development; and

• assist physicians in prescribing the appropriate tailored drug therapy based on the patient’s unique genetic makeup, a process known as pharmacogenetics.

The life sciences customer can purchase bioassays in the form of complete off-the-shelf kits, develop them internally or utilize a customized service to meet their specific needs. Although it is important to note that xMAP technology is relevant to a subset of the total life sciences market, according to strategic studies we first commissioned in 2003 and updated in 2006 and 2007 and our own internal analysis, we believe the total global market for tools and consumables used in drug discovery and development, clinical diagnostics and biomedical research represented a market of approximately $46.0 billion in end-user sales in 2007 and will grow to an estimated $65.0 billion by 2012.

The table below briefly describes the key bioassay technologies in the life sciences industry:

KEY TECHNOLOGIES	DESCRIPTION	MARKETS SERVED
BioChips/Microarrays	High-density arrays of DNA fragments or proteins attached to a flat glass or silicon surface	Biomedical research and select clinical diagnostics
Automated Immunoassays	Automated test tube-based instruments used for detecting antibodies, proteins and other analytes	Clinical diagnostics
Gels and blots	Physical separation of molecules or analytes for visualization	Clinical diagnostics and biomedical research
PCR methods	Tests which use polymerase chain reaction (PCR) technology to test DNA and ribonucleic acid (RNA)	Nucleic acid testing in clinical diagnostics and biomedical research
Microfluidics chips	Miniaturized liquid handling system on a chip	Biomedical research
Microtiter-plate based assays	Plastic trays with discrete wells in which different types of assays are performed, usually Enzyme-Linked Immuno-Sorbent Assay (ELISA) tests	Drug discovery, clinical diagnostics and biomedical research
Genotyping technologies	DNA primers or probes designed to identify small differences between DNA targets using methods such as primer extension assays, ligation assays, cleavage assays or hybridization assays, sequencing and others	Drug discovery, clinical diagnostics and biomedical research

Based on estimates contained in the strategic studies discussed above and our own internal estimates, we believe the potential life sciences market directly addressed by our xMAP technology was approximately $1.8 billion in 2007 and that it will reach $3.0 billion by 2012. In addition, we are also focused on other specialty market segments, including food safety/animal health, newborn screening and bio-defense/bio-threats. With only limited market penetration of our multiplexing xMAP technology thus far in the key market segments referenced above, we believe there remain significant growth opportunities for Luminex and our strategic partners in each of these markets.

Our xMAP Technology

Our xMAP technology combines existing biological testing techniques with advanced digital signal processing and proprietary software. With our technology, discrete bioassays are performed on the surface of color-coded microspheres. These microspheres are read in a compact analyzer that utilizes lasers and high-speed digital signal processing to simultaneously identify the bioassay and measure the individual assay results. The key features of xMAP technology include the following:

•	Multi-analyte/multi-format
	xMAP technology has been designed to simultaneously perform up to 100 distinct bioassays in a single tube or well of a microtiter plate using only a small amount of sample. Moreover, unlike most existing technologies that are dedicated to only one type of bioassay, xMAP can perform multiple types of assays including enzymatic, genetic and immunologic tests on the same instrumentation platform.
•	Flexibility/scalability
	xMAP technology allows flexibility in customizing test panels. Panels can be modified to include new bioassays in the same tube by adding additional microsphere sets. It is also scalable, meaning that there is no change in the manufacturing process and only minimal changes to the required labor to produce a small or large number of microsphere-based tests.

3

•	Both protein and nucleic acid applications on a single platform
	xMAP technology has the unique ability to analyze both proteins and nucleic acids. This allows customers to utilize a single platform to evaluate samples across more biological parameters and generate a more complete assessment of these samples. Alternative technologies are restricted to either proteins or nucleic acid, requiring customers to use two or more technologies from other vendors to get the same information.
•	High Throughput
	Our technology is currently able to perform up to 100 tests in a single tube permitting up to 9,600 unattended tests to be detected in less than an hour with only a small amount of sample. Products we are currently developing and that are planned for market release in 2009 will be able to perform 500 tests in a single tube permitting up to 96,000 unattended tests to be detected in approximately an hour with only a small amount of sample. Rapid sample analysis permits efficient use for high-throughput applications.
•	Ease of use
	Most xMAP bioassays are simple to perform. A test sample is added to a solution containing microspheres that have been coated with reagents. The solution is then processed through our xMAP technology system which incorporates proprietary software to automate data acquisition and analysis in real-time.
•	Cost effective
	By performing multiple assays at one time, xMAP technology is designed to be cost effective for customers compared to competitive techniques such as enzyme-linked immunosorbent assay (ELISA) or Real-time PCR. By analyzing only those assays in which a customer is interested, xMAP is also more cost effective than most competing microarray technologies. In addition, microsphere-based bioassays are inexpensive compared to other technologies such as biochips.

Polystyrene microspheres, approximately 5.6 microns in diameter, are a fundamental component of the xMAP technology. We purchase and manufacture microspheres and, in a proprietary process, dye them with varying intensities of a red and a near infrared dye to achieve up to 100 distinct colors. The specific dye proportions permit each color-coded microsphere to be readily identified based on its distinctive fluorescent signature. Our customers create bioassays by attaching different biochemical reactants to each distinctly colored microsphere set. These unique reactants bind, or capture, specific substances present in the test sample. The microsphere sets can then be combined in test panels as required by the user, with a current maximum of 100 tests per panel and 500 tests per panel after the market release of the FLEXMAP 3D. Customers can order either standard microspheres or magnetic microspheres.

To perform a bioassay using xMAP technology, a researcher attaches biochemicals, or reagents, to one or more sets of color-coded microspheres, which are then mixed with a test sample. This mixture is injected into the xMAP analyzer, where the microspheres pass single-file in a fluid stream through two laser beams. The first laser excites the internal dyes that are used to identify the color of the microsphere and the test being performed on the surface of the microsphere. The second laser excites a fluorescent dye captured on the surface of the microspheres that is used to quantify the result of the bioassay taking place. Our proprietary optics, digital signal processors and software record the fluorescent signature of each microsphere and compare the results to the known identity of that color-coded microsphere set. The results are analyzed and displayed in real-time with data stored on the computer database for reference, evaluation and analysis.

xTAG^® technology developed by the Assay Segment consists of several components including multiplexed PCR or target identification primers, DNA Tags, xMAP microspheres, and data analysis software. xTAG technology permits the development of molecular diagnostic assays for clinical use by hospital and reference laboratories. xTAG technology has been applied, in particular, to human genetic assays, pharmacogenetic assays, and infectious disease assays.

We have an active product development pipeline of both instrument systems and assays. We commercially sold and shipped several units of our new instrument, FlexMAP 3D, at the end of 2008, to complement our current instrument offerings. Full market release of the instrument is anticipated in 2009. The FlexMAP 3D system has twice the throughput of our LX 200 instrument and will detect, via multiplexing, up to 500 distinct biomarkers simultaneously in a single assay. This is a five fold increase in multiplexing capability over our LX200 instrument. The FlexMAP 3D system, with these enhanced capabilities, will support our market expansion into new testing segments in both research and clinical testing markets.

4

In addition to FlexMAP 3D, we have a new instrument platform under development we refer to internally as MagPix™. MagPix is an innovative technology platform using our proprietary xMAP microspheres in a new way. By virtue of its small size and ease of use, we believe MagPix will enhance the adoption of our xMAP technology in our existing markets and allow us to expand xMAP into emerging markets including research, clinical and bio-threat testing segments.

We have multiple assay development activities ongoing in the Assay Segment. The Assay Segment has assay development programs primarily focused in the areas of human genetics, pharmacogenetics and infectious disease. In 2009, we have plans to submit certain assay products to the FDA for 510(k) clearance in order to comply with recent FDA guidance for In Vitro Diagnostics, or IVD, products.

Business Strategy

Our primary goal continues to be the establishment of Luminex as an industry leader and xMAP technology as the industry standard for performing bioassays by transforming Luminex from a technology-based company to a more market-driven, customer-focused company. To achieve this goal, we have implemented and are pursuing the following strategies:

•	Focus on key market segments
	Through our strategic studies, we have identified the following key market segments: (i) life sciences research profile oriented screening and secondary screening, (ii) life sciences research RNA profiling and transcriptional screening, (iii) genetic disease and molecular infectious disease testing, and (iv) immunodiagnostics. In addition to the segments listed above, we have identified other potential market opportunities in the applied markets such as bio-defense, or bio-threat testing, and food safety and animal health testing. We will continue to employ both a partnership driven business model focused on selected key segments and a product driven business model in other key segments, working with our partners as distributors.
	We will continue to focus our commercialization efforts through strategic partners on large sectors of the life sciences industry where Luminex believes it has distinct competitive advantages over existing and emerging technologies and approaches. We define strategic partners as companies in the life sciences industry that either develop and distribute assays and tests on xMAP technology or may only distribute our xMAP technology based systems and consumables. With our partners’ support, we have targeted major pharmaceutical companies, large clinical laboratories, research institutions and major medical institutions for our principal marketing efforts. We believe these customers provide the greatest opportunity for maximizing the use of xMAP based products and continued adoption by these industry leaders will promote wider market acceptance of our xMAP technology.
•	Continue to develop strategic partnerships focused on our key market segments
	Currently, 35 of our approximately 60 strategic partners have developed reagent-based products utilizing the Luminex platform and are submitting royalties. We also have strategic partners who distribute Luminex products. During 2008, the 35 strategic partners who have commercialized reagent-based products accounted for approximately 69% of our total revenue and all of our strategic partners represented approximately 79% of our total revenue. We intend to broaden and accelerate market acceptance of xMAP technology through development, marketing and distribution partnerships with leaders in the life sciences industry. By leveraging our strategic partners’ market positions and utilizing their distribution channels and marketing infrastructure, we believe we can continue to expand our installed instrument base. Furthermore, our partners’ investments in research and development for xMAP applications provide Luminex users with more menu options than we can presently generate ourselves.
•	Develop and deliver market-leading assay products
	We are focused on maximizing the value we provide our stockholders, partners and end-user customers by developing internally and co-developing with partners content applications based on customers’ needs in key market segments. We believe that by enhancing both our partner driven model and our direct efforts with the delivery of value-added assay content, Luminex should be able to gain greater control over product development, market penetration and commercialization.

5

•	Develop next generation products
	Our research and development group is pursuing projects such as the development of consumables, automation, software and the expansion and enhancement of our multiplexing capabilities to advance our xMAP technology and its market acceptance. We are also collaborating with industry participants, biomedical research institutions and government entities to develop additional xMAP products. We also continuously consider other adjacent markets where our platform and assay offerings would be beneficial. We believe that our design, development, and manufacturing capabilities and FDA compliance track record, coupled with expertise in the FDA approval process, provide us a competitive advantage over our competitors, relating to both the commercialization of multiplex testing platforms and assay products.
•	Opportunistically pursue acquisitions that could accelerate these strategies
	We have developed analytical tools and an evaluation template to assess potential acquisition targets to accelerate our business strategies in the key markets described above. This approach led to the acquisition of Tm Bioscience in 2007. We are actively evaluating other opportunities to enhance our capabilities or our access to markets or technologies, or provide us other advantages in executing our business strategies in our key markets.

Consumables

MicroPlex^® Microspheres.Our xMAP Systems use polystyrene microspheres that are approximately 5.6 microns in diameter. We dye the microspheres in sets with varying intensities of a red and a near infrared dye to achieve up to 100 distinct color sets. Each microsphere can carry the reagents of an enzymatic, genetic or immunologic bioassay. In addition to microspheres, consumables from Luminex also include sheath fluid. Additional consumables, for which Luminex receives a royalty, in the form of reagent kits are developed and distributed by our partners.

MagPlex™ Microspheres.These microspheres feature super-paramagnetic properties that make them ideal for running automated xMAP-based assays. These microspheres can be moved or held in place by a magnetic field. Many automated sample preparation systems utilize magnetic properties to automate the sample preparation steps in an assay. Automating sample testing using MagPlex microspheres on a robotic sample preparation system minimizes hands-on technician time, improves precision, and streamlines workflow.

xTAG™ Microspheres.These microspheres are linked to a set of 100 proprietary nucleic acid capture sequences providing a “universal array” for DNA and RNA work. They are designed for conducting genotyping and other nucleic acid-based experiments in the life sciences markets. When used in conjunction with our Luminex systems, the xTAG microspheres are designed to simplify the genotyping assay development process and increase assay flexibility. The xTAG microspheres may be used in customized end-user identified single nucleotide polymorphisms (SNPs) or in pre-defined kits developed by our strategic partners.

SeroMAP™ Microspheres.These microspheres are designed for specific protein based serological applications. Certain Luminex partners use this product for enriched sensitivity in serum-based assays.

Calibration and Control Microspheres.Calibration microspheres are microspheres of known fluorescent light intensities used to calibrate the settings for the classification and reporter channel for the Luminex systems. Control microspheres are microspheres that are used to verify the calibration and optical integrity for both the classification and reporter channels for the Luminex 100 and 200 systems.

Total consumable revenue for the years ended December 31, 2008, 2007, and 2006 was $31.7 million, $19.2 million, and $15.7 million, respectively; or 30%, 26%, and 30% of total revenue, respectively. The increase in consumables as a percentage of total revenue is primarily attributable to the increase in bulk purchases as a result of increased commercial activity by our partners. Additionally, our partners reported approximately $238 million, $182 million, and $132 million of royalty bearing consumable sales during 2008, 2007 and 2006, respectively; resulting in $14.9 million, $10.2 million, and $8.2 million of royalty revenue for the years ended December 31, 2008, 2007 and 2006, respectively or 14%, 14%, and 15% of total revenue, respectively. See Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Item 8 “Financial Statements and Supplementary Data” for a detailed discussion of our financial position and results of operations by segment.

The increase in assay revenue as a percentage of total revenue is primarily attributable to the acquisition of LMD. See Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Item 8 “Financial Statements and Supplementary Data” for a detailed discussion of our financial position and results of operations by segment.

Sales and Marketing

Our sales and marketing strategy is to expand the installed base and utilization of xMAP technology. We are focused on generating recurring revenues from royalties on bioassay kits and testing services developed or performed by others that use our technology, as well as the sale of Luminex-developed assays, microspheres and other consumables. We have two key elements of our sales and marketing strategy. The first is our allegiance to Luminex’s historic strategic partner program with life sciences companies that develop applications or perform testing using our technology platforms and distribute our systems to their customers. The second is our dedication to marketing the assays developed by the Assay Segment through our strategic partners or directly to end users in segments where our partners do not participate.

We continue to use strategic partners as our primary distribution channel, and we will continue to pursue new partnerships focusing on partners with market presence in our key segments described above. Some of our strategic partners develop application-specific bioassay kits for use on our xMAP platform that they, in turn, sell to their customers thereby generating royalties for us. Certain strategic partners also perform testing services for third parties using our technology also resulting in royalties for us. Other strategic partners also buy our products, including xMAP Luminex systems and consumables, or xTAG test kits, and then resell those products to their customers. As of December 31, 2008, we had approximately 60 strategic partners, compared to approximately 58 strategic partners as of December 31, 2007. During 2008, 35 of these strategic partners had released commercialized products utilizing the Luminex platform and were submitting royalties. Of these 35 strategic partners with commercialized products, 16 companies principally serve the clinical diagnostics market and 19 companies principally serve the life science research market. These commercialized, royalty-submitting, strategic partners constituted 69% of our revenues for 2008. We also believe our strategic partners provide us with complementary capabilities in product development, regulatory expertise and sales and marketing. By leveraging our strategic partners’ bioassay testing competencies, customer relationships and distribution channels, we believe that we can continue to achieve market penetration and technology adoption without a direct sales force.

We also serve as the original equipment manufacturer (OEM) for certain strategic partners that choose to sell our xMAP technology as an embedded system under their own branding and marketing efforts.

Customers

In 2008, 2007 and 2006, two customers each accounted for more than 10% of our total revenues. One Lambda, Inc. accounted for 19%, 15%, and 15% of our total revenues in 2008, 2007 and 2006, respectively. Bio-Rad Laboratories, Inc. accounted for 17%, 20%, and 19% of our total revenues in 2008, 2007 and 2006, respectively. No other customer accounted for more than 10% of our total revenues in 2008, 2007 or 2006. The loss of either one of these customers could have a material adverse effect on our business, financial condition and results of operation. Additionally, for the annual periods ended December 31, 2008, 2007, and 2006, foreign sales to customers totaled $15.0 million, $11.4 million, and $12.2 million, respectively, representing 14%, 15%, and 23%, respectively, of our total revenues for such periods. See Note 17 to our Consolidated Financial Statements.

Technical Operations

Our Technical Operations Group provides technical support to our customers, our strategic partners and their customers. Most of our technical operations personnel have experience as biologists, biochemists, or electrical engineers and have extensive experience in academic, industrial and commercial settings. Cross training is a major focus, empowering group members to solve problems outside their primary assignment.

Remote Support

Our technical support and assay support departments assist users primarily through a toll-free hotline, internet interface and e-mail communications. We deliver “24/7” remote technical support with our staff based at our Austin location, our Toronto location, and in our European subsidiary to better serve our customer base. Personnel assist our strategic partners and customers with product orders, software, hardware, system implementation and development of their bioassays. A comprehensive software and database system is utilized to track customer interactions, follow trends and measure utilization. The information is categorized and presented to management for regular review.

Training

Through our training group, we offer comprehensive programs in basic system training, advanced assay development, instrument field service and technical support functions. A significant part of our training material is now web-based and available online. For larger customers who have many users, such as our strategic partners, training may be performed on-site at their locations.

Field Support

We currently have field service and field application personnel based across North America and in Europe in areas of our more significant system concentration. We intend to place additional field service personnel and pursue third-party service provider agreements through our certified service professional program, as required, in order to ensure responsive and cost-effective support of our customers worldwide. In addition, several of our strategic partners provide their own field service and field application support. As we continue to expand our installed base, we believe a strong, reliable, efficient field support organization is crucial to building a high level of customer satisfaction.

Research and Development

Our research and development groups seek to advance the capabilities of xMAP technology to further penetrate the life sciences and diagnostics industry to increase utilization of our systems. In addition, we collaborate with other companies, academic institutions and our customers to increase the breadth of xMAP applications. Our research and development expense for the years ended December 31, 2008, 2007 and 2006, was $18.6 million, $15.4 million and $8.7 million, respectively. Our current research and development projects include:

•

New product development

Our research and development teams, including the Assay Segment, and marketing team are working closely with both internal and external groups to design and develop products that will expand capabilities of the xMAP-based technologies. We believe that these efforts will continue to result in unique products. These products will include instrumentation, services, software and consumables including assays.

10

•	Instrument development
	Our engineering group responsible for the design of our xMAP instruments leverages proprietary electrical, optical and digital signal processing technologies to achieve high performance and reliability. This methodology enabled the recently released FlexMAP 3DTM instrument to double throughput, multiplex up to 500 analytes, enhance assay limit of detection, and greatly extends the usable dynamic range.
	To further market penetration, we are now engaged in the development of an instrument line that maintains the top features of our existing products, at a greatly reduced sales and manufacturing cost. Simultaneously, a highly efficient subset of the engineering team is engaged in the focused research necessary to extend our intellectual property position, and keep our products innovative for many years to come.
•	Assay development
	Our Assay Segment, consisting of LBG and LMD, develops new assay products that include both nucleic acid-based and protein-based assays. These assays include immunoassays and molecular diagnostic assays for the diagnostics industry, and nucleic acid-based and protein-based assays for the research life science market. All assay applications make use of our xMAP technology and our strength in multiplex technology. Our assay research and development is intended to increase the penetration of our xMAP instruments and our application menu, and to drive growth in our high-margin assay businesses.
•	Consumable development
	We continue to develop and enhance our existing consumable product line and support introduction of new product lines. These new products include calibrators, controls and microspheres with additional performance characteristics.
	Our current bead utilizes three common chemistries for the immobilization of assays on its surface. While these chemistries are well accepted in the industry, it is desirable to expand our bead chemistry capability to enhance market penetration and adoption. We continue to work on other surface chemistries to provide optimal performance in broader application areas
•	Software development
	Our software research and development teams will continue to extend xPONENT instrument control and analysis software capabilities. xPONENT software provides analysis and automation interface capabilities as well as control functions for Luminex instruments like the FLEXMAP 3D product. New versions of xPONENT will provide sophisticated data regression functionality and increased productivity through better instrument utilization. We continue to develop applications like xPONENT QC-Reviewer that will bridge the gap between the instrument control software and the Laboratory Information Systems (LIS) to provide better test results management and wider use of Luminex developed assays.
	We are maintaining and extending our system platform through our SDK as well as providing new end-user applications. Our SDK provides a straightforward platform for our strategic partners and their customers to rapidly develop their own user interface software packages. In addition, our end-user applications will allow us to provide turn key solutions to partners.
•	Automation
	We collaborate with our strategic partners and others to provide automation solutions that will integrate our various xMAP instruments with sample handling equipment and laboratory information systems to increase bioassay throughput and operational efficiencies and allow for walk-away capability.
•	Technical Applications
	In order to allow customers to expedite the production of bioassays for use on our systems, we have a technical applications group, based in Austin, Texas, that includes highly experienced biological scientists. This group works closely with our customers in their development of bioassays with the ultimate goal of faster technology adoption and commercialization.
•	Enhancing bioassay performance and operational efficiencies
	Our scientists and engineers dedicate efforts to further enhance xMAP in the areas of assay performance, such as sensitivity, precision, reliability and operational efficiencies. We are actively collecting market and customer requirements that will allow us to provide optimal features and benefits in current and future products.

Manufacturing

We have approximately 29,000 square feet of manufacturing space located at our principal executive offices in Austin, Texas. In 2002, we completed the registration of our Quality Management System (QMS) to the ISO 9001:2000 standard, which is an internationally recognized standard for quality management systems. Subsequent audits by the registrar have been and will continue to be carried out at regular intervals to ensure we are maintaining our system in compliance with ISO standards. Recertification is required every three years and we were successfully recertified as of February 23, 2007.

In July 2005, we completed the registration of our QMS to the ISO 13485:2003 Quality Management Standard and the Canadian Medical Devices Conformity System (CMDCAS) for Medical Devices. This standard includes a special set of requirements specifically related to the supply of medical devices and related services. Additionally, we manufacture to current Good Manufacturing Practice (cGMP) requirements and our QMS is implemented in accordance with FDA Quality System Regulations. In August 2006, a Level II Quality System Inspection Technique (QSIT) contract inspection was conducted. The inspection is “closed” under 21 C.F.R. 20.64 (d) (3) and the Establishment Inspection Report No. 3002524000 provided in accordance with the Freedom of Information Act (FOIA) and 21 C.F.R. Part 20. No DSHS form E-14 or FDA form 483 was issued.

Effective with our acquisition of Tm Bioscience, we have approximately 3,800 square feet of manufacturing space located in Toronto, Canada. This facility and the LMD QMS have been registered to the ISO 13485:2003 CMDCAS for Medical Devices. Additionally, we manufacture to current cGMP requirements and our QMS is implemented in accordance with FDA Quality System Regulations.

Instruments

Contract manufacturers assemble certain components of our xMAP technology systems. The remaining assembly and manufacturing of our systems are performed at our facility in Austin, Texas. The quality control and quality assurance protocols are all performed at our facility. Parts and component assemblies that comprise our xMAP technology system are obtained from a number of sources. We have identified alternate sources of supply for several of our strategic parts and component assemblies. Additionally, we have entered into supply agreements with most of our suppliers of strategic parts and component subassemblies to help ensure component availability, and flexible purchasing terms with respect to the purchase of such components. As of December 31, 2008, 5,894 Luminex systems have been sold since inception.

Microspheres

We manufacture as well as procure undyed, standard and magnetic carboxylated polystyrene microspheres. We synthesize our dyes and manufacture our dyed polystyrene microspheres using a proprietary method in our Austin, Texas manufacturing facility in large lots. We dye the microspheres with varying intensities of a red and a near infrared dye to produce our distinctly colored microsphere sets. We currently purchase polystyrene microspheres from one supplier, in accordance with a supply agreement. We believe this agreement will help ensure microsphere availability and flexible purchasing terms with respect to the purchase of such microspheres. While we believe the microspheres will continue to be available from our supplier in quantities sufficient to meet our production needs, we believe our in-house manufacturing capabilities along with other potential suppliers would provide sufficient microspheres for us if given adequate lead-time to manufacture the microspheres to our specifications.

Kits

Contract manufacturers produce certain components of our xMAP-based developed reagents. The remaining assembly and manufacturing of our developed kits are performed at either our facility in Austin, Texas or Toronto, Canada. The quality control and quality assurance protocols are all performed at our facilities. Reagents and component assemblies that comprise our xMAP technology kits are obtained from a number of sources.

12

Competition

We design our xMAP technology for use by customers across the various segments of the life sciences industry. Our competition includes companies marketing conventional testing products based on established technologies such as ELISA, real-time PCR, mass spectrometry, sequencing, gels, biochips and flow-based technologies as well as companies developing their own advanced testing technologies.

The pharmaceutical industry is a large market for the genomic, protein and high-throughput screening applications of the xMAP technology. In each application area, Luminex faces a different set of competitors. Genomic and protein testing can be performed by products available from Affymetrix Inc., Life Technologies Corporation, Becton Dickinson Company, Illumina Inc., Meso Scale Discovery, a division of Meso Scale Diagnostics LLC, and Sequenom, Inc., among others.

Our diagnostic market competitors include Abbott Laboratories, Beckman Coulter, Inc., Celera Group, Cepheid, Johnson & Johnson, Roche Diagnostics, Siemens Medical, and Hologic, Inc. among others. Some of these companies have technologies that can perform a variety of established assays. Some of these companies also offer integrated systems and laboratory automation that are designed to meet the need for improved work efficiencies in the clinical laboratory.

Competition within the academic biomedical research market is highly fragmented. There are hundreds of suppliers to this market including Amersham Pharmacia Biotech, a part of GE Healthcare, Life Technologies Corporation, and Becton Dickinson Company. Any company in this field is a potential competitor.

Intellectual Property

To establish and protect our proprietary technologies and products, we rely on a combination of patent, copyright, trademark and trade secrets laws and confidentiality agreements. We have filed for registration or obtained registration for trademarks used with our products and key technology.

We have implemented a strategy designed to optimize our intellectual property rights. For core intellectual property, we are pursuing patent coverage in the United States and those foreign countries that correspond to the majority of our anticipated customer base. We currently own 76 issued patents in the United States and foreign jurisdictions, including four in each of France, Germany and the United Kingdom, three in each of Italy and Japan, two in each of Singapore, Australia and Canada and one in each of Hong Kong, Korea, India and Israel, all directed to various aspects and applications of our products and technology. In addition, our patent portfolio includes 201 other pending patent applications in the United States and their corresponding international and foreign counterparts in major industrial markets. We believe our patents and pending claims provide, or will provide, protection for systems and technologies that allow “real time” multiplexed analytical techniques for the detection and quantification of many analytes from a single sample. We also hold a patent covering the precision-dyeing process that we use to dye our microspheres. We have been granted a patent on our “Zero Dead Time” sampling architecture, which uses digital over-sampling to measure the area of a fluorescence pulse instead of “peak detection,” giving increased sensitivity with no lost events. Other issued patents and pending patent applications cover specific aspects and applications of our xMAP technology and on-going molecular research. However, as a result of a procedural omission, we are unable to pursue a patent application in Japan corresponding to our U.S. patent for real-time multiplexing techniques. We also have patents covering key aspects of xTAG technology utilized in our assay products.

The source code for our proprietary software is protected as a trade secret and/or as a copyrighted work. Aspects of this software also are covered by an issued patent.

We also rely on trade secret protection of our intellectual property. We attempt to protect our trade secrets by entering into confidentiality agreements with strategic partners, third parties, employees and consultants. Our employees and third-party consultants also sign agreements requiring that they assign to us their interests in inventions and original works of expression and any corresponding patents and copyrights arising from their work for us.

Government Regulation

Food and Drug Administration

The Food and Drug Administration regulates medical devices pursuant to various statutes, namely the Federal Food, Drug and Cosmetic Act as amended and supplemented by the Medical Device Amendments of 1976, the Safe Medical Devices Act of 1990, the Medical Device Amendments of 1992, the FDA Export Reform and Enhancement Act of 1996, the FDA Modernization Act of 1997, the Public Health, Security and Bioterrorism Preparedness and Response Act of 2002, the Medical Device User Fee and Modernization Act of 2002, and the Project BioShield Act of 2004. Medical devices, as defined by statute, include instruments, machines, in vitro reagents or other similar or related articles, including any components, parts, or accessories of such articles that are intended for use in the diagnosis of disease or other condition or in the cure, mitigation, treatment or prevention of disease; or are intended to affect the structure or function of the body and do not achieve their intended purpose through chemical action or metabolization. The FDA classifies medical devices intended for human use into three classes. For Class I devices, general controls (for example, labeling and good manufacturing practices) provide reasonable assurance of safety and effectiveness. Class II devices are products for which general controls do not provide reasonable assurance of safety and effectiveness and for which there is sufficient information to establish special controls (for example, guidelines and patient registries). Class III devices are products for which neither general nor special controls provide reasonable assurance of safety and effectiveness. Generally, Class III includes devices that support or sustain human life, are for uses that are substantially important in preventing impairment of human health, are used as a stand alone assay for patient screening or diagnosis of disease, or present a potential, unreasonable risk of illness or injury.

We manufacture a version of the Luminex 100 and Luminex 200 — the Luminex 100 Integrated System (Luminex 100 IS) and the Luminex 200 Integrated System (Luminex 200 IS), respectively — for use with diagnostic assay kits that are available through our strategic partners. For FDA purposes, the Luminex 100 IS and Luminex 200 IS are IVD cleared and are considered a component of our partners’ kit products. Depending on the particular kit’s regulatory classification into Class I, II, or III and its intended use, kits manufactured by our strategic partners that are used in conjunction with our technology may be subject to FDA clearance or approval before they can be marketed and sold. After incorporating the Luminex 100 IS or Luminex 200 IS into their products, our strategic partners are required to make various premarket submissions such as premarket approval applications, premarket notifications and/or investigational device exemption applications to the FDA for their products and are required to comply with numerous requirements and restrictions prior to clearance or approval of the applications. There can be no assurance that the FDA will file, clear or approve our strategic partners’ submissions.

We manufacture kit products that are intended for Research Use Only applications as well as kits that are of the regulatory classification of Class II exempt in our Austin, Texas facility. Additionally, the Assay Segment manufactures kit products that are IVD cleared as well as intended for Research Use Only and Investigational Use Only applications.

In December, 2007 we submitted to the FDA our request for 510(k) clearance on our Luminex 200 IS. On December 13, 2007 the FDA received our 510(k) # k073506 submission for the Luminex 200 IS System. On March 7, 2008, the instrument received FDA 510(k) clearance. All future diagnostic assay kits subject to FDA clearance may reference the 501(k) # for the instrument in their respective applications.

Our instruments use lasers to identify the bioassays and measure their results. Therefore, we are required to ensure that our products comply with FDA regulations pertaining to the performance of laser products. These regulations are intended to ensure the safety of laser products by establishing standards to prevent exposure to excess levels of laser radiation. There can be no assurance that the FDA will agree with our interpretation and implementation of these regulations.

14

We, and our strategic partners, may be subject to periodic inspection by the FDA for, among other things, compliance with the FDA’s current good manufacturing practice regulations. These regulations, also known as the Quality System Regulations, govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging and servicing of all finished medical devices intended for human use. Additionally, our strategic partners may be subject to other premarket and post market controls such as labeling, complaint handling, medical device reporting, corrections and removals reporting, and record keeping requirements. If the FDA has evidence demonstrating that a company is not in compliance with applicable regulations, it can detain or seize products, request or, in certain circumstances, require a recall, impose operating restrictions, enjoin future violations, recommend criminal prosecution to the Department of Justice, and assess civil and criminal penalties against us, our officers, or our employees. Other regulatory agencies may have similar powers.

Medical device laws and regulations are also in effect in many countries outside of the United States. These range from comprehensive preapproval requirements for medical products to simpler requests for product data or certification. The number and scope of these requirements are increasing. There can be no assurance that we, and our strategic partners, will be able to obtain any approvals that may be required to market xMAP technology products outside the United States.

The Assay Segment produces CE marked products which are subject to the European Union (EU) Directive. CE marking is self declaration, not issued by a third party. CE Marking is based on mandatory EU Directives adopted and enforced in all member countries of the EU. A product that is not CE marked is automatically considered to be non-compliant. The law is enforced through market surveillance by appointed national enforcement agencies. Imported products are checked for compliance at customs offices.

The State Food and Drug Administration, P.R. China (SFDA) is the Government regulation authority in charge of safety management of drug, food, health food and cosmetics for the Peoples Republic of China. In December 2007 we submitted the application for a certificate to combine both Luminex 100 and 200 into one product called Luminex System. This certificate is a required registration and approval to import our products into China.

Failure by us, or our strategic partners, to comply with applicable federal, state and foreign medical product laws and regulations would likely have a material adverse effect on our business. In addition, federal, state and foreign regulations regarding the manufacture and sale of medical devices and components of such devices are subject to future changes. We cannot predict what impact, if any, such changes might have on our business, but any such change could have a material impact.

WEEE

As part of the Council Directive 2002/26 of February 13, 2003, Waste Electrical and Electronic Equipment (WEEE), we are in compliance with the requirements, beginning on August 13, 2005, regarding the labeling and disposal of some of our products containing electronic devices in each of the EU member states where our regulated products are distributed. While we are taking steps to comply with the requirements of WEEE, we cannot be certain that we will comply with the implementation of WEEE in all EU member states.

European IVD Directive

The EU’s regulation of in vitro medical devices is under the In Vitro Diagnostic Directive (IVDD) 98/79/EC of October 27, 1998, as implemented in the EU member states.

The principle behind the IVDD is that no in vitro device or accessory may be placed on the market or put into service unless it satisfies the essential requirements set forth in the IVDD. Devices considered to meet the essential requirements must bear the CE marking of conformity when they are placed on the market. The responsibility for placing the CE marking on the device lies with the manufacturer. A manufacturer placing devices on the market in its name is required to notify its national competent authorities.

15

Luminex Corporation has declared that the LX100 IS and the LX200 IS are classified as a self-declaration device and is in conformity with Article 1, Article 9, Annex I (Essential Requirements), and Annex III, and the additional provisions of IVDD 98/79/EC. However, there can be no assurance that the EU member states will agree with our interpretation and implementation of these regulations. As the European marketplace continues to be material to our operations, failure by us or our strategic partners to comply with the IVDD could have a material adverse effect on our business.

Environmental

We are subject to federal, state and local laws and regulations relating to the protection of human health and the environment. In the course of our business, we are involved in the handling, storage and disposal of certain chemicals and biohazards. The laws and regulations applicable to our operations include provisions that regulate the discharge of materials into the environment. Some of these environmental laws and regulations impose “strict liability,” rendering a party liable without regard to negligence or fault on the part of such party. Such environmental laws and regulations may expose us to liability for environmental contamination, including remediation costs, natural resource damages and other damages as a result of the conduct of, or conditions caused by, us or others, or for acts that were in compliance with all applicable laws at the time such acts were performed. In addition, where contamination may be present, it is not uncommon for neighboring landowners and other third parties to file claims for personal injury, property damage and recovery of response costs. Although it is our policy to use generally accepted operating and disposal practices in accordance with applicable environmental laws and regulations, hazardous substances or wastes may have been disposed or released on, under or from properties owned, leased or operated by us or on, under or from other locations where such substances or wastes have been taken for disposal. These properties may be subject to investigation, remediation and monitoring requirements under federal, state and local environmental laws and regulations. We believe that our operations are in substantial compliance with applicable environmental laws and regulations. However, failure to comply with these environmental laws and regulations may result in the imposition of administrative, civil and criminal penalties or other liabilities. We do not believe that we have been required to expend material amounts in connection with our efforts to comply with environmental requirements or that compliance with such requirements will have a material adverse effect upon our capital expenditures, results of operations or competitive position. Because the requirements imposed by such laws and regulations may frequently change and new environmental laws and regulations may be adopted, we are unable to predict the cost of compliance with such requirements in the future, or the effect of such laws on our capital expenditures, results of operations or competitive position. Moreover, the modification or interpretation of existing environmental laws or regulations, the more vigorous enforcement of existing environmental laws or regulations, or the adoption of new environmental laws or regulations may also negatively impact our strategic partners, which in turn could have a material adverse effect on us and other similarly situated component companies.

Employees

As of both February 23, 2009 and December 31, 2008, we had a total of 384 employees and contract employees, as compared with 343 as of December 31, 2007. The increase from 2007 to 2008 is mainly due to personnel added related to development, production, regulatory clearance, and quality control for our new instrument, FlexMAP 3D, and our new bead products and assays. None of our employees are represented by a collective bargaining agreement, and we have not experienced any work stoppage. We believe that relations with our employees are good.

Segments

Financial information relating to our reportable segments for the years ended December 31, 2008, 2007, and 2006 can be found in Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Item 8 “Financial Statements and Supplementary Data”.

ITEM 1A. RISK FACTORS

We have a limited history of profitability and had an accumulated deficit of approximately $84.7 million as of December 31, 2008.

We have incurred significant net losses since our inception. At December 31, 2008, we had an accumulated deficit of approximately $84.7 million. In order to remain profitable, we need to sustain or increase our revenues while achieving reasonable cost and expense levels. We believe that in 2008 we achieved a level of consistent profitability from our continuing operations; however, we cannot be certain that we can sustain or increase profitability on a quarterly or annual basis. If we fail to achieve operating results in line with market expectations, the market price of our common stock will likely decline. Furthermore, as we continue to utilize cash to support operations, acquisitions and research and development efforts, we may further decrease the cash available to us. As of December 31, 2008, cash, cash equivalents and short-term and long-term investments totaled $124.1 million, compared to $34.2 million at December 31, 2007 and $45.7 million at December 31, 2006. The increase since December 31, 2007 is primarily attributable to the cash proceeds from our secondary public offering in June of 2008 of $74.7 million and cash provided from operations of $13.9 million.

We expect our operating results to continue to fluctuate from quarter to quarter.

The sale of our instrumentation and assay products typically involves a significant technical evaluation and commitment of capital by us, our partners and the end-user. Accordingly, the sales cycle associated with our products typically is lengthy and subject to a number of significant risks, much of which is beyond our control, including partners’ budgetary constraints, inventory management practices, regulatory approval and internal acceptance reviews. As a result of this lengthy and unpredictable sales cycle, our operating results have historically fluctuated significantly from quarter to quarter. We expect this trend to continue for the foreseeable future.

The vast majority of our system sales are made to our strategic partners. Our partners typically purchase instruments in three phases during their commercialization cycle: first, instruments necessary to support internal assay development; second, instruments for sales force demonstrations; and finally, instruments for resale to their customers. As a result, most of our system placements are highly dependent on the continued commercial success of our strategic partners and can fluctuate from quarter to quarter as our strategic partners move from phase to phase. We expect this trend to continue for the foreseeable future.

Our assay products are sometimes sold to large customers. The ordering and consumption patterns of these customers can fluctuate, affecting the timing of shipments and revenue recognition. In addition, certain products assist in the diagnosis of illnesses that are seasonal, and customer orders can fluctuate for this reason.

Because of the effect of bulk purchases, defined as the purchase of $100,000 or more of consumables in a quarter, and the introduction of seasonal components to our assay menus, we experience fluctuations in the percentage of our quarterly revenues derived from our highest margin items, consumables, royalties and assays. Our gross margin percentage is highly dependent upon the mix of revenue components each quarter. These fluctuations contribute to the variability and lack of predictability of both gross margin percentage and total gross profit from quarter to quarter. We expect this trend to continue for the foreseeable future.

Due to the early stage of the market for molecular tests, projected growth scenarios for the Assay Segment are highly volatile and are based on a number of underlying assumptions that may or may not prove to be valid, including the performance of strategic partners that distribute our Assay Segment products.

17

Our success depends significantly on the establishment and maintenance of successful relationships with our strategic partners. Currently, a limited number of strategic partners account for a majority of our revenue and the loss of any one of these partners or their inability to perform to expectations could have a material adverse effect on our business, financial condition and results of operations.

The development and commercialization of our xMAP technology is highly dependent on our ability to establish successful strategic relationships with a number of partners. For the twelve months ended December 31, 2008, we had 35 strategic partners submitting royalties as compared to 30 for the twelve months ended December 31, 2007. Two customers, One Lambda, Inc. and Bio-Rad Laboratories, Inc., accounted for 36% of consolidated total revenue in the twelve months ended December 31, 2008 (19% and 17 %, respectively). For comparative purposes, these same two customers accounted for 35% of total revenue (Bio-Rad Laboratories, Inc. - 20%; One Lambda, Inc. — 15%) in the twelve months ended December 31, 2007. No other customer accounted for more than 10% of total revenue during the twelve months ended December 31, 2008. We had only two additional partners who individually represented 5% or more of our total revenue and collectively represented 12% of our revenue for the year ended December 31, 2008. In total, for the year ended December 31, 2008, our top five partners accounted for 53% of our total revenue. In total, for the year ended December 31, 2007, our top five partners accounted for 52% of our total revenue. The loss of any of our significant strategic partners, or any of our significant customers, could have a material adverse effect on our growth and future results of operations. The Assay Segment is dependent on a few significant customers with respect to sales of its genetic test kits. If any significant customer discontinues its relationship with the Assay Segment for any reason, or reduces or postpones current or expected purchase commitments for the Assay Segment’s products, the Assay Segment’s results from operations could be materially adversely affected.

Delays in implementation, delays in obtaining regulatory approval, changes in strategy or the financial difficulty of our strategic partners for any reason could have a material adverse effect on our business, financial condition and results of operations.

Our ability to enter into agreements with additional strategic partners depends in part on convincing them that our technology can help achieve and accelerate their goals or efforts. We will expend substantial funds and management efforts with no assurance that any additional strategic relationships will result. We cannot assure you that we will be able to negotiate additional strategic agreements in the future on acceptable terms, if at all, or that current or future strategic partners will not pursue or develop alternative technologies either on their own or in collaboration with others. Some of the companies we are targeting as strategic partners offer products competitive with our xMAP technology, which may hinder or prevent strategic relationships. Termination of strategic relationships, or the failure to enter into a sufficient number of additional strategic relationships on favorable terms, could reduce sales of our products, lower margins on our products and limit the creation of market demand for and acceptance of our products.

In most of our strategic relationships we have granted our strategic partners non-exclusive rights with respect to commercialization of our products and technology. The lack of exclusivity could deter existing strategic partners from commercializing xMAP technology and may deter new strategic partners from entering into agreements with us.

A significant portion of our future revenues will come from sales of our systems and the development and sale of bioassay kits utilizing our technology by our strategic partners and from use of our technology by our strategic partners in performing services offered to third parties. We believe that our strategic partners will have economic incentives to develop and market these products, but we cannot accurately predict future sales and royalty revenues because most of our existing strategic partner agreements do not include minimum purchase requirements or minimum royalty commitments. In addition, we have no control with respect to our strategic partners’ sales personnel and how they prioritize products based on xMAP technology nor can we control the timing of the release of products by our strategic partners. The amount of these revenues depends on a variety of factors that are outside our control, including the amount and timing of resources that current and future strategic partners devote to develop and market products incorporating our technology. Further, the development and marketing of certain bioassay kits will require our strategic partners to obtain governmental approvals, which could delay or prevent their commercialization efforts. If our current or future strategic partners do not successfully develop and market products based on our technology and obtain necessary government approvals, our revenues from product sales and royalties will be significantly reduced.

18

Current economic conditions and the uncertain economic outlook may adversely impact our business, results of operations, financial condition or liquidity.

Recently, global economic conditions have deteriorated and may remain challenging for the foreseeable future. The credit markets and the financial services industry have been experiencing a period of unprecedented turmoil and upheaval characterized by the bankruptcy, failure, collapse or sale of various financial institutions and an unprecedented level of intervention from the United States federal government. These conditions not only limit our access to capital but also make it extremely difficult for our customers, our vendors and us to accurately forecast and plan future business activities, and they could cause U.S. and foreign businesses and consumers to slow spending on our products and services, which would delay and lengthen sales cycles. Some of our customers rely on government research grants to fund technology purchases. If negative trends in the economy affect the government’s allocation of funds to research, there may be less grant funding available for certain of our customers to purchase technologies like those Luminex sells. Certain of our partners and their and our customers may face challenges gaining timely access to sufficient credit or may otherwise be faced with budget constraints, which could result in decreased purchases of, or development of products based on, our products or in an impairment of their ability to make timely payments to us. If our partners and our customers do not make timely payments to us, we may be required to assume greater credit risk relating to those customers, increase our allowance for doubtful accounts and our days sales outstanding would be negatively impacted. Although we maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments and such losses have historically been within our expectations and the provisions established, we may not continue to experience the same loss rates that we have in the past, especially given the current turmoil of the worldwide economy. Additionally, these economic conditions and market turbulence may also impact our suppliers causing them to be unable to supply in a timely manner sufficient quantities of customized components, thereby impairing our ability to manufacture on schedule and at commercially reasonable costs.

If the FDA or other governmental laws and regulations change in ways that we do not anticipate and we fail to comply with those regulations that affect our business, we could be subject to enforcement actions, injunctions and civil and criminal penalties or otherwise be subject to increased costs that could delay or prevent marketing of our products.

The production, testing, labeling, marketing and distribution of our products for some purposes and products based on our technology are subject to governmental regulation by the United States Food and Drug Administration (FDA) and by similar agencies in other countries. Some of our products and products based on our technology for in vitro diagnostic purposes are subject to clearance by the FDA prior to marketing for commercial use. To date, eight strategic partners have obtained such clearances. Others are anticipated. The process of obtaining necessary FDA clearances can be time-consuming, expensive and uncertain. Further, clearance may place substantial restrictions on the indications for which the product may be marketed or to whom it may be marketed. In addition, because some of our products employ laser technology, we are also required to comply with FDA requirements relating to radiation performance safety standards.

Periodically the FDA issues guidance documents that represent the FDA’s current thinking on a topic. These issues are initially issued in draft form prior to final rule generally with enforcement discretion for some grace period of time. Changes made through this process may impact the release status of products offered and our ability to market those products affected by the change. For example, the FDA released on September 14, 2007 the final document “Guidance for Industry and FDA Staff Commercially Distributed Analyte Specific Reagents (ASRs): Frequently Asked Questions.” This guidance may limit or delay distribution of assays on our platform, including assays developed and distributed by our Assay Segment, to the extent additional regulatory clearance is required prior to distribution. The final document was released with an enforcement discretion period of one year from date of issue.

Cleared medical device products are subject to continuing FDA requirements relating to, among others, manufacturing quality control and quality assurance, maintenance of records and documentation, registration and listing, import/export, adverse event and other reporting, distribution, labeling and promotion and advertising of medical devices. Our inability or the inability of our strategic partners to obtain required regulatory approval or clearance on a timely or acceptable basis could harm our business. In addition, failure to comply with applicable regulatory requirements could subject us or our strategic partners to regulatory enforcement action, including warning letters, product seizures, recalls, withdrawal of clearances, restrictions on or injunctions against marketing our products or products based on our technology, and civil and criminal penalties.

19

Medical device laws and regulations are in effect within the United States and also in many countries outside the United States. These range from comprehensive device clearance requirements for some or all of our medical device products to requests for product data or certifications regarding the hazardous material content of our products. As part of the European Council Directive 2002/96 of February 13, 2003 (WEEE), we are expected to comply with certain requirements regarding the collection, recycling and labeling of our products containing electronic devices beginning on August 13, 2005 in each of the European Union, or EU, member states where our regulated products are distributed. While we are taking steps to comply with the requirements of WEEE, we cannot be certain that we will comply with the national stage implementation of WEEE in all member states. Our products are currently exempt from the European Council Directive 2002/95 of January 27, 2003, Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (RoHS), which requires the removal of certain specified hazardous substances from certain products beginning July 1, 2006 in each of the member states. However, the EU has indicated that it may, and it is generally expected it will, include medical devices, including some of our products, under the jurisdiction of RoHS. If this exemption is revoked, it could result in increased costs to us and we cannot assure you we will ultimately be able to comply with RoHS or related requirements in other jurisdictions. In addition, the State of California adopted the Electronic Waste Recycling Act, effective January 1, 2007, which requires the California Department of Toxic Substances Control to adopt regulations to prohibit the sale of electronic devices in California if they are also prohibited from sale in the EU under the RoHS directive because they contain certain heavy metals. The number and scope of these requirements are increasing and we will likely become subject to further similar laws in other jurisdictions. Failure to comply with applicable federal, state and foreign medical device laws and regulations may harm our business, financial condition and results of operations. We are also subject to a variety of other laws and regulations relating to, among other things, environmental protection and workplace health and safety.

Our strategic partners and customers expect our organization to operate on an established quality management system compliant with FDA Quality System Regulations and industry standards, the In Vitro Diagnostic Directive 98/79/EC of 27 October 1998 (Directive) as implemented nationally in the EU member states and industry standards, such as ISO 9000. We became ISO 9001:2000 certified in March 2002 and self-declared our Luminex 100 and Luminex 200 devices are in conformity with Article 1, Article 9, Annex I (Essential Requirements), and Annex III, and the additional provisions of the Directive as of December 7, 2003. Subsequent audits are carried out annually to ensure we maintain our system in substantial compliance with ISO and other applicable regulations and industry standards. We became ISO 13485:2003 and Canadian Medical Device Conformity Assessment System (CMDCAS) certified in July 2005. In August 2006 a Level II QSIT contract inspection was conducted in accordance with CPGM 7382.845, Inspection of Medical Device Manufacturers, PAC 82845B, Medical Device Level II Inspections pursuant to the FDA Dallas District Office FY 06 Workplan and the DSHS Drugs & Medical Device Group FY 06 Workplan. The inspection is “closed” under 21 C.F.R. 20.64 (d) (3) and the Establishment Inspection Report No. 3002524000 provided in accordance with the FOIA and 21 C.F.R. Part 20. No DSHS form E-14 or FDA form 483 was issued. Failure to maintain compliance with FDA, CMDCAS and EU regulations and other medical device laws, or to obtain applicable registrations where required, could reduce our competitive advantage in the markets in which we compete and also decrease satisfaction and confidence levels with our partners.

If our technology and products do not become widely used in the life sciences and clinical diagnostics industries, it is unlikely that we can maintain or increase profitability.

Life sciences companies have historically conducted biological tests using a variety of technologies, including bead-based analysis. In certain testing areas, our xMAP technology is relatively new and unproven, and the use of our technology by life sciences companies is limited. The commercial success of our technology depends upon its widespread adoption as a method to perform bioassays. In order to be successful, we must convince potential partners to utilize our system instead of competing technologies. Market acceptance depends on many factors, including our ability to:

• convince prospective strategic partners and customers that our technology is an attractive alternative to other technologies for pharmaceutical, research, clinical, biomedical and genetic testing and analysis;

• encourage these partners to develop and market products using our technology;

• manufacture products in sufficient quantities with acceptable quality and at an acceptable cost;

• obtain and maintain sufficient pricing and royalties from partners on such Luminex products; and

• place and service sufficient quantities of our products, including the ability to provide the level of service required in the mainstream clinical diagnostics market segment.

Because of these and other factors, our products may not gain or sustain sufficient market acceptance to again achieve, maintain or increase profitability.

20

Our reliance on strategic partners to market our products makes forecasting difficult.

Primarily as a result of our reliance on partner performance, it is difficult to accurately forecast future operating results. Our operating expenses are largely based on anticipated revenue trends, and a high percentage of our expenses are, and will continue to be, fixed in the short-term. The level of our revenues depends upon the rate and timing of the adoption of our technology as a method to perform bioassays. In addition, we currently anticipate that the vast majority of future sales of our products and products incorporating our technology will be made by our strategic partners. For the following reasons, estimating the timing and amount of sales of these products that may be made by our strategic partners is particularly difficult:

• We have no control over the timing or extent of product development, marketing or sale of our products by our strategic partners.

• Most of our strategic partners are not committed to minimum purchase commitments, and we do not control the incentives provided by our strategic partners to their sales personnel.

• A significant number of our strategic partners intend to produce clinical diagnostic applications that may need to be approved by the FDA, or other regulatory bodies in jurisdictions outside of the United States.

• Certain strategic partners may have unique requirements for their applications and systems. Assisting the various strategic partners may strain our research and development and manufacturing resources. To the extent that we are not able to timely assist our strategic partners, the commercialization of their products will likely be delayed.

• Certain strategic partners may fail to deliver products that satisfy market requirements, or such products may fail to perform properly.

• We have limited access to partner confidential corporate information. A sudden unexpected change in ownership, strategy or other material event could adversely impact partner purchases of our products.

• Partners tend to order in bulk prior to the production of new lots of their products and prior to major product development initiatives. The frequency of these bulk purchases is difficult to predict and may cause large fluctuations in microsphere sales quarter to quarter.

The life sciences industry is highly competitive and subject to rapid technological change, and we may not have the resources necessary to compete successfully.

We compete with companies in the United States and abroad that are engaged in the development and production of similar products. We will continue to face intense competition from existing competitors and other companies seeking to develop new technologies. Many of our competitors have access to greater financial, technical, scientific, research, marketing, sales, distribution, service and other resources than we do. These companies may develop technologies that are superior alternatives to our technologies or may be more effective at commercializing their technologies in products.

The life sciences industry is characterized by rapid and continuous technological innovation. We may need to develop new technologies for our products to remain competitive. One or more of our current or future competitors could render our present or future products obsolete or uneconomical by technological advances. In addition, the introduction or announcement of new products by us or others could result in a delay of or decrease in sales of existing products, as we await regulatory approvals and as customers evaluate these new products. We may also encounter other problems in the process of delivering new products to the marketplace such as problems related to design, development or manufacturing of such products, and as a result we may be unsuccessful in selling such products. Our future success depends on our ability to compete effectively against current technologies, as well as to respond effectively to technological advances by developing and marketing products that are competitive in the continually changing technological landscape.

21

Our success depends on our ability to service and support our products directly or in collaboration with our strategic partners.

To the extent that we or our strategic partners fail to maintain a high quality level of service and support for xMAP technology products, there is a risk that the perceived quality of our xMAP technology products will be diminished in the marketplace. Likewise, we may fail to provide the level, quantity or quality of service expected by the marketplace. This could result in slower adoption rates and lower than anticipated utilization of xMAP products which could have a material adverse affect on our business, financial condition and results of operations.

The property rights we rely upon to protect the technology underlying our products may not be adequate to maintain market exclusivity. Inadequate intellectual property protection could enable third parties to exploit our technology or use very similar technology and could reduce our ability to distinguish our products in the market.

Our success depends, in part, on our ability to obtain, protect and enforce patents on our technology and products and to protect our trade secrets, including the intellectual property of entities we may acquire. Any patents we own may not afford full protection for our technology and products. Others may challenge our patents and, as a result, our patents could be narrowed or invalidated. In addition, our current and future patent applications may not result in the issuance of patents in the United States or foreign countries. Competitors may develop products that are not covered by our patents. Further, there is a substantial backlog of patent applications at the U.S. Patent and Trademark Office and certain patent offices in foreign jurisdictions, and the approval or rejection of patent applications may take several years.

We have obtained 76 patents in the United States and foreign jurisdictions directed to various aspects and applications of our products and technology. We have 201 pending applications in the United States and foreign jurisdictions. In Japan, due to a procedural omission, we are unable to obtain patent protection for our method of “real time” detection and quantification of multiple analytes from a single sample on our platform technology similar to the protection we have obtained in the United States. Although we are pursuing patent protection in Japan for other aspects of our technology and products, we may not be able to prevent competitors from developing and marketing technologies and products similar to our xMAP technology in Japan. We also have patents covering key aspects of xTAG technology utilized in our assay products.

We require our employees, consultants, strategic partners and other third parties to execute confidentiality agreements. Our employees and third-party consultants also sign agreements requiring that they assign to us their interests in inventions and original expressions and any corresponding patents and copyrights arising from their work for us. In addition, we have implemented a patent process to file patent applications on our key technology. However, we cannot guarantee that these agreements or this patent process will provide us with adequate protection against improper use of our intellectual property or disclosure of confidential information. In addition, in some situations, these agreements may conflict with, or be subject to, the rights of third parties with whom our employees, consultants or advisors have prior employment or consulting relationships. Further, others may independently develop substantially equivalent proprietary technology, techniques and products or otherwise gain access to our trade secrets. Our failure to protect our proprietary information and techniques may inhibit or limit our ability to exclude certain competitors from the market.

In order to protect or enforce our patent rights, we may have to initiate legal proceedings against third parties, such as infringement suits or interference proceedings. These legal proceedings could be expensive, take significant time and/or divert management’s attention from other business concerns. These proceedings may cause us to lose the benefit of some of our intellectual property rights, the loss of which may inhibit or preclude our ability to exclude certain competitors from the market. These proceedings also may provoke these third parties to assert claims against us. The patent position of companies like ours generally is highly uncertain, involves complex legal and factual questions and has recently been the subject of much litigation. No consistent policy has emerged from the U.S. Patent and Trademark Office or the courts regarding the breadth of claims allowed or the degree of protection afforded under patents like ours.

22

Our success depends partly on our ability to operate without infringing on or misappropriating the proprietary rights of others.

We have been (and from time to time we may be) notified that third parties consider their patents or other intellectual property relevant to our products. We may be sued for infringing the intellectual property rights of others, including claims with respect to intellectual property of entities we may acquire. We are currently a party to a suit brought by The Research Foundation of the State University of New York against Luminex and LMD, alleging, among other claims, that LMD breached its license agreement with SUNY by failing to pay royalties allegedly owed under the agreement, as described in Item 3 “Legal Proceedings” below. In addition, we may find it necessary, if threatened, to initiate a lawsuit seeking a declaration from a court that we do not infringe on the proprietary rights of others or that their rights are invalid or unenforceable. Intellectual property litigation is costly, and, even if we prevail, the cost of such litigation could affect our profitability. Furthermore, litigation is time consuming and could divert management’s attention and resources away from our business. If we do not prevail in any litigation, we may have to pay damages and could be required to stop the infringing activity or obtain a license. Any required license may not be available to us on acceptable terms, if at all. Moreover, some licenses may be nonexclusive, and therefore, our competitors may have access to the same technology licensed to us. If we fail to obtain a required license or are unable to design around a patent, we may be unable to sell some of our products, which could have a material adverse affect on our business, financial condition and results of operations.

We require collaboration with other organizations in obtaining relevant biomarkers, access to oligonucleotides and enzymes that are patented or controlled by others. If we cannot continue to obtain access to these areas or identify freedom to operate opportunities, our business, financial condition and results of operations could be negatively affected.

We have only produced our products in limited quantities, and we may experience problems in scaling our manufacturing operations or delays or component shortages that could limit the growth of our revenue.

To date, we have produced our products in limited quantities relative to the quantities necessary to achieve desired revenue growth. We may not be able to produce sufficient quantities or maintain consistency between differing lots of consumables. If we encounter difficulties in scaling our manufacturing operations as a result of, among other things, quality control and quality assurance issues and availability of components and raw material supplies, we will likely experience reduced sales of our products, increased repair or re-engineering costs due to product returns, and defects and increased expenses due to switching to alternate suppliers, any of which would reduce our revenues and gross margins.

We presently outsource certain aspects of the assembly of our systems to contract manufacturers. Because of a long lead-time to delivery, we are required to place orders for a variety of items well in advance of scheduled production runs. We recently increased our flexibility to purchase strategic components within shorter lead times by entering into supply agreements with the suppliers of these components. Although we attempt to match our parts inventory and production capabilities to estimates of marketplace demand, to the extent system orders materially vary from our estimates, we may experience continued constraints in our systems production and delivery capacity, which could adversely impact revenue in a given fiscal period. Should our need for raw materials and components used in production continue to fluctuate, we could incur additional costs associated with either expediting or postponing delivery of those materials. In an effort to control costs, during the last quarter of 2005 we implemented a lean production system. Managing the change from discrete to continuous flow production requires time and management commitment. Lean initiatives and limitations in our supply chain capabilities may result in part shortages that delay shipments and cause fluctuations in revenue in a given period.

We currently purchase certain key components of our product line from a limited number of outside sources and may only be available through a limited number of providers. We do not have agreements with all of our suppliers. While we currently believe that we will be able to satisfy our forecasted demand for our kits, the failure to find alternative suppliers in the event of a supply failure at any of our current vendors at reasonably comparable prices could have a material adverse effect on our business, financial condition and results of operations. Additionally, we have entered into supply agreements with most of our suppliers of strategic reagents and component subassemblies to help ensure component availability, and flexible purchasing terms with respect to the purchase of such components. Our reliance on our suppliers and contract manufacturers exposes us to risks including:

• the possibility that one or more of our suppliers or our assemblers that do not have supply agreements with us could terminate their services at any time without penalty;

• the potential obsolescence and/or inability of our suppliers to obtain required components;

23

• the potential delays and expenses of seeking alternate sources of supply or manufacturing services;

• the inability to qualify alternate sources without impacting performance claims of our products;

• reduced control over pricing, quality and timely delivery due to the difficulties in switching to alternate suppliers or assemblers; and

• increases in prices of raw materials and key components.

Consequently, in the event that supplies of components or work performed by any of our assemblers are delayed or interrupted for any reason, our ability to produce and supply our products could be impaired.

International business operations create additional operational and legal risk.

Our future profitability will depend in part on our ability to grow and ultimately maintain our product sales in foreign markets, particularly in Asia and Europe. Our plans to expand globally will expose us to additional foreign currency risk in multiple currencies. Our operations outside the United States are subject to additional risks, including:

• changes in or interpretations of foreign law that may adversely affect our ability to sell our products, perform services or repatriate profits to the United States;

• the imposition of tariffs;

• hyperinflation or economic or political instability in foreign countries;

• imposition of limitations on or increase of withholding and other taxes on remittances and other payments by foreign subsidiaries;

• conducting business in places where business practices and customs are unfamiliar and unknown;

• the burden of complying with complex and changing foreign regulatory requirements;

• longer accounts receivable collection times;

• the imposition of restrictive trade policies, including export restrictions;

• worldwide political conditions;

• the imposition of inconsistent laws or regulations;

• reduced protection of intellectual property rights in some foreign countries;

• the imposition or increase of investment requirements and other restrictions by foreign governments;

• longer collection cycles for account receivables;

• the interpretation of contractual provisions governed by foreign laws in the event of a contract dispute;

• uncertainties relating to foreign laws, including labor laws, and legal proceedings;

• significant currency fluctuations;

• having to comply with a variety of U.S. laws, including the Foreign Corrupt Practices Act; and

• having to comply with U.S. export control regulations and policies that restrict our ability to communicate with non-U.S. employees and supply foreign affiliates, partners and customers.

24

The capital spending policies of our customers have a significant effect on the demand for our products.

Our customers include clinical diagnostic, pharmaceutical, biotechnological, chemical and industrial companies, and the capital spending policies of these companies can have a significant effect on the demand for our products. These policies are based on a wide variety of factors, including governmental regulation or price controls, the resources available for purchasing research equipment, the spending priorities among various types of analytical equipment and the policies regarding capital expenditures during recessionary periods. Any decrease in capital spending by life sciences companies could cause our revenues to decline. As a result, we are subject to significant volatility in revenue. Therefore, our operating results can be materially affected (negatively and positively) by the spending policies and priorities of our customers.

If we become subject to product liability claims, we may be required to pay damages that exceed our insurance coverage.

Our business exposes us to potential product liability claims that are inherent in the testing, production, marketing and sale of biotechnological, human (including genetic) diagnostic and therapeutic products. Although we believe that we are reasonably insured against these risks and we generally have limited indemnity protections in our supplier agreements, there can be no assurance that we will be able to obtain insurance in amounts or scope sufficient to provide us with adequate coverage against all potential liabilities. A product liability claim in excess of our insurance coverage or claim that is outside or exceeds our indemnity protections in our supplier agreements or a recall of one of our products would have to be paid out of our cash reserves.

If third-party payors increasingly restrict payments for healthcare expenses or fail to adequately pay for multi-analyte testing, we may experience reduced sales which would hurt our business and our business prospects.

Third-party payors, such as government entities and healthcare programs, health maintenance organizations and private insurers, are continually seeking to reduce healthcare expenses. The federal government has also recently reduced the funding for certain government sponsored healthcare programs which has caused these third party payors to seek further reduction in medical expenses. These reductions may decrease demand for our products and the price we can charge. Increasingly, Medicaid and other third-party payors are challenging the prices charged for medical services, including clinical diagnostic tests. They are also attempting to contain costs by limiting coverage and the reimbursement level of tests and other healthcare products. In addition, cost containment initiatives by governmental or educational entities or programs may reduce funding for genetic research and development activities and retard the growth of the genetic testing marketing. Without adequate coverage and reimbursement, consumer demand for tests will decrease. Decreased demand could cause sales of our products, and sales and services by our strategic partners, to fall. In addition, decreased demand could place pressure on us, or our strategic partners, to lower prices on these products or services, resulting in lower margins. Reduced sales or margins by us, or our strategic partners, would hurt our business, profitability and business prospects.

We may in the future incur substantial debt that could restrict our operations.

We may incur indebtedness in the future for, among other purposes, funding operating expenses and/or costs related to future expansions and acquisitions. This indebtedness could have adverse consequences on us, including:

• limiting our ability to compete and our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate;

• limiting our ability to borrow additional funds for working capital, capital and research and development expenditures, acquisitions and general corporate or other purposes; and

• exposing us to interest rate risk.

To the extent incurred, our debt service obligations will require us to use a portion of our operating cash flow to pay interest and principal on indebtedness instead of for other corporate purposes, including funding future expansion of our business and ongoing capital expenditures. Our ability to repay or refinance our debt depends on our successful financial and operating performance. Our financial and operating performance depends upon a number of factors, many of which are beyond our control, as further described in this Item 1A “Risk Factors.”

25

We may be unsuccessful in implementing our acquisition strategy. We may face difficulties integrating acquired entities with our existing businesses.

Acquisitions of assets or entities designed to accelerate the implementation of our strategic plan are an element of our long-term strategy. We may be unable to identify and complete appropriate future acquisitions in a timely manner and no assurance can be provided that the market price of potential business acquisitions will be acceptable. In addition, many of our competitors have greater financial resources than we have and may be willing to pay more for these businesses or selected assets. In the future, should we identify suitable acquisition targets, we may be unable to complete acquisitions or obtain the financing, if necessary, for these acquisitions on terms favorable to us. Generally, potential acquisitions pose a number of risks, including, among others, that:

•	we may not be able to accurately estimate the financial effect of acquisitions on our business;
•	future acquisitions may require us to assume liabilities, incur large and immediate write-offs, issue capital stock potentially dilutive to our stockholders or spend significant cash or may result in a decrease in our future operating income or operating margins;
•	we may be unable to realize the anticipated benefits and synergies from acquisitions as a result of inherent risks and uncertainties, including difficulties integrating acquired businesses or retaining their key personnel, partners, customers or other key relationships, entering market segments in which we have no or limited experience, and risks that acquired entities may not operate profitably or that acquisitions may not result in improved operating performance;
•	acquisitions and subsequent integration of these companies may disrupt our business and distract our management from other responsibilities; and
•	the costs of unsuccessful acquisition efforts may adversely affect our financial performance.
	Other risks of integration include:
•	disparate information technology, internal control, financial reporting and record-keeping systems;
•	differences in accounting policies, including those requiring judgment or complex estimation processes;
•	new partners or customers who may operate on terms and programs different than ours;
•	additional employees not familiar with our operations;
•	facilities or operations in remote locations or potentially foreign jurisdictions and the inherent risks of operating in unfamiliar legal and regulatory environments; and
•	new products, including the risk that any underlying intellectual property associated with such products may not have been adequately protected or that such products may infringe on the proprietary rights of others.

We rely on the innovation and resources of larger industry participants and public programs to advance genomic research and educate physicians/clinicians on genetic diagnostics.

The linkages between genetic anomalies that our products detect and the underlying disease states are not always fully medically correlated. Additionally, the availability of correlated genetic markers is dependent on significant investment in genomic research, often funded through public programs for which there are no assurances of on-going support. Should any government limit patent rights to specific genetic materials, private investment in this area could also be significantly curtailed. In addition, the adoption of genetic diagnostics is dependent to a great extent on the education and training of physicians and clinicians. We do not have the resources to undertake such training, and are relying on larger industry participants and professional medical colleges to establish, communicate and educate physicians and clinicians on best practices related to genetic diagnostics.

We are subject to evolving legislative, judicial and ethical standards on use of technology and biotechnology.

The adoption of genetic testing is occurring within the broader context of a myriad of decisions related to genetic patenting and genotyping. Issues associated with health insurance, data access, intellectual property protection, national and international legislative initiatives and other variables may have a significant impact on the wide spread adoption of genetic testing or on specific segments or tests within the genetic testing market.

26

Our success depends on our ability to attract and retain our management and staff.

We depend on the principal members of our management and scientific staff, including our chief executive officer, Patrick Balthrop, and our operations, marketing, research and development, technical support, technical service and sales staff. The loss of services of key members of management could delay or reduce our product development, marketing and sales and technical support efforts. In addition, recruiting and retaining qualified scientific and other personnel to perform research and development, technical support, technical service and marketing and sales work will be critical to our success. There is a shortage in our industry of qualified management and scientific personnel, and competition for these individuals is intense. There can be no assurance that we will be able to attract additional and retain existing personnel necessary to achieve our business objectives.

Our stock price has been and is likely to continue to be volatile.

The trading price of our common stock has been and is likely to continue to be highly volatile and subject to wide fluctuations in price. This volatility is in response to various factors, many of which are beyond our control, including:

• actual or anticipated variations in quarterly operating results from historical results or estimates of results prepared by securities analysts;

• announcements of technological innovations or new products or services by us or our competitors;

• announcements by us of significant acquisitions, strategic partnerships, joint ventures or capital commitments;

• conditions or trends in the life science, biotechnology and pharmaceutical industries;

• additions or departures of key personnel;

• changes in financial estimates by securities analysts;

• general economic conditions and interest rates;

• instability in the United States and other financial markets and the ongoing and possible escalation of unrest in the Middle East, other armed hostilities or further acts or threats of terrorism in the United States or elsewhere;

• sales of our common stock; and

• the potential adverse impact of the secondary trading of our stock on foreign exchanges which are subject to less regulatory oversight than the NASDAQ Global Market, without our permission, and the activity of the market makers of our stock on such exchanges, including the risk that such market makers may engage in naked short sales and/or other deceptive trading practices which may artificially depress or otherwise affect the price of our common stock on the NASDAQ Global Market.

In addition, the stock market in general, and the NASDAQ Global Market and the market for technology companies in particular, has experienced significant price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. Further, there has been particular volatility in the market prices of securities of life sciences companies. These broad market and industry factors may seriously harm the market price of our common stock, regardless of our operating performance. In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has often been instituted. A securities class action suit against us could result in substantial costs, potential liabilities and the diversion of management’s attention and resources.

Anti-takeover provisions in our certificate of incorporation, bylaws and stockholder rights plan and Delaware law could make a third party acquisition of us difficult.

Our certificate of incorporation, bylaws and stockholder rights plan contain provisions that could make it more difficult for a third party to acquire us, even if doing so would be beneficial to our stockholders. We are also subject to certain provisions of Delaware law that could delay, deter or prevent a change in control of us. These provisions could limit the price that investors might be willing to pay in the future for shares of our common stock.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 2. PROPERTIES

Our principal research and development, manufacturing and administrative facilities are located in Austin, Texas, and consist of approximately 109,000 square feet of leased space pursuant to a lease agreement which expires July 31, 2010. We maintain an additional 10,172 square feet of leased space in Oosterhout, Netherlands and approximately 27,000 square feet of leased office and manufacturing space in Toronto, Canada. We believe these facilities are adequate for our current needs.

ITEM 3. LEGAL PROCEEDINGS

On January 16, 2008, Luminex and LMD were served with a complaint, filed by The Research Foundation of the State University of New York (“SUNY”) in Federal District Court for the Northern District of New York, alleging, among other claims, that LMD breached its license agreement with SUNY by failing to pay royalties allegedly owed under the agreement. The complaint seeks an undetermined amount of damages as well as injunctive relief. On February 9, 2008, Luminex and LMD filed an answer to this complaint denying all claims brought by SUNY. The Court issued a scheduling order on January 16, 2009 to establish deadlines for completion of discovery. A trial date has not been set. The parties are engaging in the discovery process. There can be no assurance that we will successfully defend this suit or that a judgment against us would not materially adversely affect our operating results.

When and if it appears probable in management’s judgment that we will incur monetary damages or costs, in connection with any claims or proceedings, and such costs can be reasonably estimated, liabilities will be recorded in the financial statements and charges will be recorded against earnings. Ongoing legal fees are expensed in the period incurred. Though there can be no assurances, our management believes that the resolution of existing routine matters and other incidental claims, taking into account accruals and insurance, will not have a material adverse effect on our financial condition or results of operations.

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

The following information should be read in conjunction with the Consolidated Financial Statements and the accompanying Notes included below in Item 8 and “Risk Factors” included above in Item 1A of this Annual Report onForm 10-K. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements.

Overview

We develop, manufacture and sell proprietary biological testing technologies and products with applications throughout the life sciences and diagnostics industries. Our xMAP^® technology, an open architecture, multiplexing technology, allows simultaneous analysis of up to 100 bioassays from a small sample volume, typically a single drop of fluid, by reading biological tests on the surface of microscopic polystyrene beads called microspheres. Products we are currently developing and that are anticipated for market release in 2009 will be able to perform up to 500 simultaneous bioassays from a small sample volume. xMAP technology combines this miniaturized liquid array bioassay capability with small lasers, digital signal processors and proprietary software to create a system offering advantages in speed, precision, flexibility and cost. Our xMAP technology is currently being used within various segments of the life sciences industry which includes the fields of drug discovery and development, clinical diagnostics, genetic analysis, bio-defense, protein analysis and biomedical research.

Our end-user customers and partners, which include laboratory professionals performing research, clinical laboratories performing tests on patients as ordered by a physician and other laboratories, have a fundamental need to perform high quality testing as efficiently as possible. Luminex has adopted a business model built around strategic partnerships. We have licensed our xMAP technology to companies, which then develop products that incorporate the xMAP technology into products that they sell to the end-user. Luminex develops and manufactures the proprietary xMAP laboratory instrumentation and the proprietary xMAP microspheres and sells these products to its partners. Our partners then sell xMAP instrumentation and xMAP-based reagent consumable products, which run on the instrumentation, to the end-user laboratory. Luminex was founded on this model, and our success to date has been due to this model. As of December 31, 2008, Luminex had approximately 60 strategic partners and these partners have purchased from Luminex over 5,800 xMAP-based systems. Of the 60 strategic partners, 35 have released commercialized reagent-based products utilizing our technology.

Beginning in 2006, we began developing proprietary assays through LBG. This development was supplemented in 2007 by our acquisition of Tm Bioscience. Our assay segment focuses on the molecular diagnostics market.

Luminex has several forms of revenue that result from this partner model:

• System revenue is generated from the sale of our xMAP systems and peripherals. Currently, system revenue is derived from the sale of the Luminex 100 and 200 analyzers, our FLEXMAP 3D system, optional XY Platform and Sheath Delivery Systems.

• Consumable revenue is generated from the sale of our dyed polystyrene microspheres and sheath fluid. Our larger commercial and development partners often purchase these consumables in bulk to minimize the number of incoming qualification events and to allow for longer development and production runs.

• Royalty revenue is generated when a partner sells a kit incorporating our proprietary microspheres to an end user or when a partner utilizes a kit to provide a testing result to a user. End users can be facilities such as testing labs, development facilities and research facilities that buy prepared kits and have specific testing needs or testing service companies that provide assay results to pharmaceutical research companies or physicians.

• Assay revenue is generated from the sale of our kits which are a combination of chemical and biological reagents and our proprietary bead technology used to perform diagnostic and research assays on samples. Assay revenue includes revenue from LMD since the effective date our acquisition of LMD on March 1, 2007. Assay revenue generated from LBG is also classified here. Prior to our forming the assay segment, assay revenue generated from LBG was recorded in other revenue as it did not constitute a material amount of total revenue.

33

• Service revenue is generated when a partner or other owner of a system purchases a service contract from us after the warranty has expired. Service contract revenue is amortized over the life of the contract and the costs associated with those contracts are recognized as incurred.

• Other revenue consists of items such as training, shipping, parts sales, license revenue, grant revenue, contract research and development fees and milestone revenue and other items that individually amount to less than 5% of total revenue.

2008 Highlights

• Luminex grew total revenue by approximately 39% to $104.4 million over 2007 revenue

• Gross margin percentage of 68%, up from 61% in 2007

• Delivered first commercial shipments of new instrument, FLEXMAP 3D

• Record system shipments of 915 for the year ended December 31, 2008, including three FLEXMAP 3D shipments

• Cumulative world wide system sales to date of 5,894 systems, including three FLEXMAP 3D placements

• For the year ended 2008, royalty revenue increased 45% and consumables revenue increased 65% over the prior calendar year

Change in Cash Position

Our cash, cash equivalents and investments increased by approximately $90.0 million during the twelve months ended December 31, 2008 due primarily to our secondary public offering of 4,025,000 shares which raised net proceeds of $74.7 million and closed on June 30, 2008 and our management of receivables and inventory. In addition, we secured a revolving credit facility for up to $15.0 million, which, as of December 31, 2008 and subject to the borrowing base requirements, would have allowed for borrowings of up to approximately $10.4 million. We elected not to renew this credit facility as it matured on February 26, 2009, given our significant cash, cash equivalents, and investment balance and in light of our projected capital needs for the foreseeable future.

Segment Information

Luminex has two reportable segments: The Technology Segment and the Assay Segment. The Technology Segment, which is our base business, consists of system sales to partners, raw bead sales, royalties, service and support of the technology, and other miscellaneous items. The Assay Segment consists of LBG and LMD. This segment is primarily involved in the development and sale of assays on xMAP technology for use on Luminex’s installed base of systems.

Future Operations

We expect anticipated 2009 revenue growth to be driven by sustained adoption of our core technology coupled with assay introduction and commercialization by the Assay Segment. The anticipated continued shift in revenue concentration towards higher margin items, such as assays, consumables and royalties, should provide favorable gross margins. Additionally, we believe that a sustained investment in R&D is necessary in order to meet the needs of our marketplace; however, we estimate that R&D expenditures for 2009 will decline as a percentage of revenue from 2008 towards our long term target of 15% of revenue.

We expect our primary challenges to be the continued adoption of partner products incorporating Luminex technology, the current economic conditions and its potential impact on the purchase and sales of our partners and customers and our ability to improve or maintain on operating margins, commercialization, regulatory acceptance and market adoption of output from the Assay Segment and expanding our footprint and reputation within our identified target market segments.

Critical Accounting Policies

The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with United States generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. The following is a discussion of our most critical accounting policies used in the preparation of our financial statements, and the judgments and estimates involved under each. We also have other significant accounting policies that do not involve critical accounting estimates because they do not generally require us to make estimates and judgments that are difficult or subjective. These are described in Note 1 of our Consolidated Financial Statements provided herein in Item 8. Estimates and assumptions are reviewed periodically. Actual results may differ from these estimates under different assumptions or conditions.

Revenue Recognition.Revenue on sales of our products is recognized when persuasive evidence of an agreement exists, delivery has occurred, the fee is fixed and determinable and collectability is probable. Generally, these criteria are met at the time our product is shipped. If the criteria for revenue recognition are not met at the time of shipment, the revenue is deferred until all criteria are met. Royalty revenue is generated when a partner sells products incorporating our technology, provides testing services to third parties using our technology or resells our consumables. Royalty revenue is recognized as it is reported to us by our partners, generally quarterly; therefore, the underlying end-user sales may be related to prior periods due to the timing of when the revenue is reported to us by our partners. We also sell extended service contracts for maintenance and support of our products. Revenue for service contracts is recognized ratably over the term of the agreement. Revenues from contracts with multiple elements are recognized as each element is earned based on the relative fair value of each element when there are no undelivered elements that are essential to the functionality of the delivered elements and when the amount is not contingent upon delivery of the undelivered elements.

Upfront payments from our strategic partners are nonrefundable and will be recognized as revenue as our strategic partners purchase products or applied against royalty payments. Nonrefundable license fees are amortized into revenue over the estimated life of the license agreements.

Grant revenue consists of amounts earned under research agreements with government grants, which is recognized in the period during which the related costs are incurred.

Inventory Valuation.Inventories are valued at the lower of cost or market value and have been reduced by an allowance for excess and obsolete inventories. The two major components of the allowance for excess and obsolete inventory are (i) a specific reserve for inventory items that we no longer use in the manufacture of our products or that no longer meet our specifications and (ii) a reserve against slow moving items for potential obsolescence. The total estimated allowance is reviewed on a regular basis and adjusted based on management’s review of inventories on hand compared to estimated future usage and sales. While management believes that adequate write-downs for inventory obsolescence have been made in the consolidated financial statements, scientific and technological advances will continue and we could experience additional inventory write-downs in the future. However, we do not believe this estimate is subject to significant variability.

Warranties.We provide for the estimated cost of initial product warranties at the time revenue is recognized. While we engage in product quality programs and processes, our warranty obligation is affected by product failure rates, material usage and service delivery costs incurred in correcting a product failure. While management believes that adequate reserve has been made in the consolidated financial statements for product warranties, should actual product failure rates, material usage or service delivery costs differ from our estimates, revisions to the estimated warranty liability would be required. However, we do not believe this estimate is subject to significant variability.

Accounts Receivable and Allowance for Doubtful Accounts.We continuously monitor collections and payments from our customers and maintain allowances for doubtful accounts based upon our historical experience and any specific customer collection issues that we have identified. While such credit losses historically have been within our expectations, there can be no assurance that we will continue to experience the same level of credit losses that we have in the past. A significant change in the liquidity or financial position of any one of our significant customers, or a further deterioration in the economic environment, in general, could have a material adverse impact on the collectability of our accounts receivable and our future operating results, including a reduction in future revenues and additional allowances for doubtful accounts. However, we do not believe this estimate is subject to significant variability.

Purchase Price Allocation, Intangibles and Goodwill.The purchase price allocation for acquisitions requires extensive use of accounting estimates and judgments to allocate the purchase price to the identifiable tangible and intangible assets acquired, including in-process research and development (IPR&D), and liabilities assumed based on their respective fair values. Intangible assets with definite lives are amortized over the assets’ estimated useful lives using the straight-line method. We periodically review the estimated useful lives of our identifiable intangible assets, taking into consideration any events or circumstances that might result in a diminished fair value or revised useful life.

Statement of Financial Accounting Standards (SFAS) No. 142 “Goodwill and Other Intangible Assets” requires that goodwill and certain intangible assets be assessed for impairment at a reporting unit level at least annually. We evaluate the carrying value of goodwill and other intangible assets annually or more frequently if there is evidence that certain events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable. If the carrying amount of a reporting unit exceeds its fair value, then a goodwill impairment test is performed to measure the amount of the impairment loss, if any. We would recognize an impairment charge for any amount by which the carrying amount of goodwill exceeds its fair value. Determining the fair value of goodwill is judgmental in nature and often involves the use of estimates and assumptions. Estimates of fair value are primarily determined using discounted cash flows and market comparisons. As of December 31, 2008, we have $39.6 million of goodwill, which has been allocated to the assay segment which includes LMD. We have performed our annual test of goodwill, and have determined there has been no impairment of goodwill as of December 31, 2008.

Accounting for Income Taxes.We calculate a provision for income taxes using the asset and liability method, under which deferred tax assets and liabilities are recognized by identifying the temporary differences arising from the different treatment of items for tax and accounting purposes. In determining the future tax consequences of events that have been recognized in our financial statements or tax returns, judgment is required. Differences between the anticipated and actual outcomes of these future tax consequences could have a material impact on our consolidated results of operations or financial position. The recognition of deferred tax assets is reduced by a valuation allowance if it is more likely than not that the tax benefits will not be realized. We regularly review our deferred tax assets for recoverability and establish a valuation allowance based on historical income, projected future income, the expected timing of the reversals of existing temporary differences and the implementation of tax-planning strategies.

Stock compensation. We recognize the fair-value of stock-based compensation transactions in the Consolidated Statement of Income in accordance with SFAS No. 123(R), “Share-Based Payment” (“SFAS 123(R)”). The fair value of our stock-based awards is estimated at the date of grant using the Black-Scholes option pricing model. The Black-Scholes valuation calculation requires us to estimate key assumptions such as expected volatility, expected term and risk-free rate of return. Calculation of expected volatility is based on historical volatility. The expected term is calculated using the contractual term of the options as well as an analysis of the Company’s historical exercises of stock options. The estimate of risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant. We have never paid cash dividends and do not currently intend to pay cash dividends, thus we have assumed a 0% dividend yield. As part of the requirements of SFAS 123(R), we are required to estimate potential forfeitures of stock grants and adjust compensation cost recorded accordingly. The estimate of forfeitures is based on historical forfeiture performance and will be adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from such estimates. See Note 14 to the Consolidated Financial Statements for a further discussion on stock-based compensation.

Revenue.Total revenue increased to $104.4 million for the year ended December 31, 2008 from $75.0 million in 2007. The increase in revenue was primarily attributable to an increase of $17.2 million in consumable and royalty revenues in the Technology Segment and continued growth in the Assay Segment, including the effects of the acquisition of LMD. In addition, system sales increased to 915 systems from 862 systems for the corresponding prior year period.

A breakdown of revenue for the years ended December 31, 2008 and 2007 is as follows (in thousands):

	Year Ended December 31,
	2008		2007
System sales	$	28,136	$	24,428
Consumable sales		31,724		19,199
Royalty revenue		14,897		10,244
Assay revenue		18,715		11,323
Service contracts		5,363		4,431
Other revenue		5,612		5,385
	$	104,447	$	75,010

We continue to have revenue concentration in a limited number of strategic partners, as the top five customers, by revenue, accounted for 53% of total revenue in 2008. In particular, two customers accounted for 36% of 2008 total revenue (19% and 17% respectively). No other customer accounted for more than 10% of total revenue. See the segment discussions that follow on pages 40-43 for additional revenue discussion.

Gross Profit.Gross profit increased to $70.9 million for the year ended December 31, 2008, as compared to $46.1 million for the year ended December 31, 2007. The gross profit margin rate (gross profit as a percentage of total revenue) was 68% for the year ended December 31, 2008, up from 61% the year ended December 31, 2007. The increase in gross margin rate was primarily attributable to the continuing shift in revenue concentration towards higher margin items such as assays, consumables and royalties. The increase in gross profit was primarily attributable to the overall increase in revenue. We anticipate continued fluctuation in gross profit margin and related gross profit primarily as a result of variability in partner bulk purchases and the absolute number of quarterly system sales.

Research and Development Expense.Research and development expenses increased to $18.6 million for the year ended December 31, 2008 from $15.4 million for the year ended December 31, 2007. The increase was primarily attributable to incorporation of the results of LMD for the full twelve months in 2008 compared to the inclusion of only ten months of operating results of LMD in the year ended December 31, 2007, as the acquisition was consummated on March 1, 2007, and to a lesser extent, to increased activity by the Assay Segment related to product development, an increase in materials, and additional personnel costs associated with the addition of employees and contract employees. Research and development headcount at December 31, 2008 was 116 as compared to 111 at December 31, 2007. As a percentage of revenue, research and development expense decreased to 18% in 2008 as compared with 21% in 2007. Our current expectation is for research and development expenses to be between 15% and 18% of total revenue for 2009.

Selling, General and Administrative Expense.Selling, general and administrative expenses increased to $49.0 million for the year ended December 31, 2008 from $40.7 million for the comparable period in 2007. The increase was primarily attributable to incorporation of the results of LMD for the full twelve months in 2008 compared to the inclusion of only ten months of operating results of LMD in the year ended December 31, 2007, and to a lesser extent additional personnel costs associated with the addition of employees and an increase in stock compensation expense. Selling, general and administrative headcount at December 31, 2008 was 134 as compared to 119 at December 31, 2007. As a percentage of revenue, selling, general and administrative expenses reduced to 47% in 2008 as compared to 54% in 2007.

Other Income, net.Other income, net decreased to $1.1 million for the year ended December 31, 2008 from $1.7 million for the year ended December 31, 2007 partially due to approximately $480,000 in costs related to a potential acquisition that did not occur, offset by the interest income on the net proceeds from our secondary offering. In addition, the average rate earned on current invested balances decreased to 2.0% for the year ended December 31, 2008 from 5.0% for the year ended December 31, 2007. This decrease in the average rate earned is the result of an overall decrease in market rates compared to the prior year period. See additional discussions by segment below.

Settlement of litigation.We settled our pending litigation with Rules Based Medicine (RBM) on October 15, 2007. As part of the settlement, Luminex received a cash payment of $12.5 million. $11.5 million was recognized as part of net income in 2007, while $1.0 million was deferred for licensing rights granted to RBM from Luminex.

Gain on settlement of liability.$2.3 million was recognized in the year ended December 31, 2007 related to the settlement of a liability related to the renegotiation of a contract acquired as part of the acquisition of Tm Bioscience.

Revenue.Total revenue increased to $75.0 million for the year ended December 31, 2007 from $53.0 million in 2006. The increase in revenue was primarily attributable to the Assay Segment (including the acquisition of LMD and increased activity by LBG) and, in addition, to a lesser extent increases in consumable and royalty revenues and system sales in the Technology Segment.

A breakdown of revenue for the years ended December 31, 2007 and 2006 is as follows (in thousands):

	Year Ended December 31,
	2007		2006
System sales	$	24,428	$	20,644
Consumable sales		19,199		15,676

Service contracts		4,431		3,450
Other revenue		5,385		4,972
	$	75,010	$	52,989

The top five customers, by revenue, accounted for 52% of total revenue in 2007. In particular, two customers accounted for 35% of 2007 total revenue (20% and 15%, respectively). No other customer accounted for more than 10% of total revenue.

Gross Profit.Gross profit increased to $46.1 million for the year ended December 31, 2007, as compared to $32.3 million for the year ended December 31, 2006. The gross profit margin rate (gross profit as a percentage of total revenue) was 61% for the year ended December 31, 2007, consistent with the year ended December 31, 2006. The flat gross margin rate was primarily attributable to the acquisition of a company with lower gross margins offset by an increase in high margin consumables and royalty revenue. The increase in gross profit, in dollar amount was primarily attributable to the overall increase in revenue.

Research and Development Expense.Research and development expenses increased to $15.4 million for the year ended December 31, 2007 from $8.7 million for the year ended December 31, 2006. The increase was primarily attributable to increases in personnel costs associated with the addition of employees in 2007 related to the Tm Bioscience acquisition. Research and development headcount at December 31, 2007 was 111 as compared to 61 at December 31, 2006. As a percentage of revenue, research and development expense increased to 21% in 2007 as compared with 16% in 2006.

Selling, General and Administrative Expense.Selling, general and administrative expenses increased to $40.7 million for the year ended December 31, 2007 from $24.2 million for the comparable period in 2006. The increase was primarily attributable to the acquisition of Tm Bioscience and to a lesser extent an increase in stock compensation expense and the impact of foreign exchange transaction losses related to foreign currency denominated balances. As a percentage of revenue, selling, general and administrative expenses were 54% in 2007 and 46% in 2006.

Other Income, net.Other income, consisting primarily of interest in our cash and investment balances, decreased to $1.7 million for the year ended December 31, 2007 from $2.1 million for the year ended December 31, 2006.

Settlement of litigation.We settled our pending litigation with RBM on October 15, 2007. As part of the settlement, Luminex received a cash payment of $12.5 million. $11.5 million was recognized as part of net income, while $1.0 million was deferred for licensing rights granted to RBM from Luminex.

Gain on settlement of liability.$2.3 million was recognized in the year ended December 31, 2007 related to the settlement of a liability related to the renegotiation of a contract acquired as part of the acquisition of Tm Bioscience.

Segment Results of Operations

Technology Segment

Selected financial data for the year ended December 31, 2008 and 2007 of our Technology Segment is as follows:

	Year Ended December 31,
							Variance			Variance

Revenue.Total revenue increased 34% to $83.6 million for the year ended December 31, 2008 from $62.4 million in 2007. The increase in revenue was primarily attributable to an increase in consumable, royalty and system revenue as a result of our efforts to accelerate instrument placements, menu expansion, and increasing utilization of our partners’ assays on our technology.

A breakdown of revenue in the Technology Segment for the years ended December 31, 2008 and 2007 is as follows (in thousands):

	Year Ended December 31,
	2008		2007
System sales	$	26,408	$	23,320
Consumable sales		31,678		19,197
Royalty revenue		14,897		10,213
Service contracts		5,290		4,431
Other revenue		5,294		5,275
	$	83,567	$	62,436

The top five customers, by revenue, accounted for 62% of total revenue in 2008 compared to 61% in 2007. In particular, two customers accounted for 45% of 2008 total technology segment revenue (24% and 21%, respectively) compared to 42% of 2007 total technology segment revenue (18% and 24%, respectively). No other customer accounted for more than 10% of total technology segment revenue.

System and peripheral component sales increased 13% to $26.4 million for the year ended December 31, 2008 from $23.3 million for the year ended December 31, 2007. System sales increased to 875 systems for 2008 as compared to 838 systems in the prior year, bringing total systems sold to date to over 5,800 as of December 31, 2008.

40

Consumable sales, comprised of microspheres and sheath fluid, increased 65% to $31.7 million during 2008 from $19.2 million in 2007. This is primarily the result of an increase in bulk purchases due to increased commercial activity by our partners. Partners who reported royalty bearing sales accounted for $28.2 million, or 89%, of total consumable sales for the year ended December 31, 2008. In addition, during 2008 we had 49 bulk purchases of consumables totaling approximately $26.1 million as compared with 41 bulk purchases totaling approximately $14.3 million in the prior year. A bulk purchase is defined as the purchase of $100,000 or more of consumables in a quarter.

Royalty revenue increased 46% to $14.9 million for the year ended December 31, 2008 from $10.2 million for the year ended December 31, 2007. We believe this is primarily the result of our efforts to accelerate instrument placements, menu expansion, and increasing utilization of our partner’s assays on our technology. We expect modest fluctuations in the number of commercial partners submitting royalties based upon the varying contractual terms, consolidations among partners, differing reporting and payment requirements, and the addition of new partners. For the year ended December 31, 2008, we had 35 commercial partners submit royalties as compared with 30 for the year ended December 31, 2007. Additionally, the 30 partners from whom we recognized $10.2 million in royalties in 2007 represented approximately $14.6 million of the total royalties in 2008, an increase of approximately 43% over their prior year payments. Total royalty bearing sales reported to us by our partners were approximately $238.5 million for the year ended December 31, 2008 as compared to $167.0 million for the year ended December 31, 2007.

Service contracts, comprised of extended warranty contracts earned ratably over the term of a contract, increased 19% to $5.3 million during 2008 from $4.4 million in 2007. This increase is attributable to additional resources allocated to the sale of extended service agreements resulting in increased penetration of the expanded installed base. At December 31, 2008, we had 967 Luminex systems covered under extended service agreements and $2.1 million in deferred revenue related to those contracts. At December 31, 2007, we had 799 Luminex systems covered under extended service agreements and $1.8 million in deferred revenue related to those contracts.

Other revenue, comprised of training revenue, shipping revenue, miscellaneous part sales, amortized license fees, reagent sales and grant revenue, stayed flat at $5.3 million for the years ended December 31, 2008 and 2007.

Gross Profit.The gross profit margin percentage (gross profit as a percentage of total revenue) for the Technology Segment increased to 66% for the year ended December 31, 2008 from 61% for the year ended December 31, 2006. Gross profit for the Technology Segment increased to $54.8 million for the year ended December 31, 2008, as compared to $37.9 million for the year ended December 31, 2007. The increase in gross profit margin percentage was primarily attributable to changes in revenue mix between our higher and lower gross margin items. The increase in gross profit was primarily attributable to the overall increase in revenue coupled with the increase in gross margin. Consumables and royalties, two of our higher margin items, comprised $46.6 million, or 56%, of Technology Segment revenue for the year ended December 31, 2008 and $29.4 million, or 47%, for the year ended December 31, 2007.

Operating expenses.Research and development expenses increased to $10.8 million for the year ended December 31, 2008 from $8.9 million for the year ended December 31, 2007. The increase was primarily attributable to an increase in materials and supplies and additional personnel costs associated with the addition of employees in the Technology Segment. The increase in materials and supplies and the number of employees has allowed us to enhance our focus on development of our system, consumable and software products and the expansion of applications for use on our platforms. As a percentage of revenue, research and development expense was 13% in 2008 and 14% in 2007.

Selling, general and administrative expenses increased to $34.9 million for the year ended December 31, 2008 from $29.4 million for the comparable period in 2007. The increase was primarily related to additional personnel costs and the related stock compensation and travel costs associated with the increase in employees and contract employees of the Technology Segment to 99 at December 31, 2008 from 81 at December 31, 2007 and higher legal and professional fees. As a percentage of revenue, selling, general and administrative expenses were 42% in 2008 and 47% in 2007.

Settlement of litigation.We settled our pending litigation with RBM on October 15, 2007. As part of the settlement, Luminex received a cash payment of $12.5 million. $11.5 million was recognized as part of net income in 2007, while $1.0 million was deferred for licensing rights granted to RBM from Luminex.

Revenue.Revenues were derived from LBG for the twelve months ended December 31, 2008 and 2007 and also from LMD from March 1, 2007 through December 31, 2008.

A breakdown of revenue in the Assay Segment for the years ended December 31 is as follows (in thousands):

	Year Ended December 31,
	2008		2007
System sales	$	1,728	$	1,108
Consumable sales		46		2

Assay revenue		18,715		11,323
Other revenue		318		110
	$	20,880	$	12,574

The top five customers, by revenue, accounted for 72% of total revenue in 2008 compared to 64% in 2007. In particular, the top two customers in 2008 accounted for 48% of total revenue (27% and 21%, respectively) compared to the top two customers of 2007 which accounted for 46% of total revenue (33% and 13%, respectively). The majority of our Assay Segment revenues are generated from the sale of test kits. Historically, over 70% of our total assay revenue was derived from our CF product line. In the year ended December 31, 2008, as a result of the launch of our RVP product in January, 2008, our top two assay segment products were CF and RVP. These two products represented over 83% of total assay revenue in the year ended December 31, 2008. System sales during the year ended 2008 in the Assay Segment increased to 40 systems compared to 24 systems in 2007. Other revenue includes contract research and development fees and commercial milestone revenue.

Gross profit. The gross profit margin percentage (gross profit as a percentage of total revenue) for the Assay Segment increased to 78% for the year ended December 31, 2008 from 65% for the year ended December 31, 2007. Gross profit for the Assay Segment increased to $16.2 million for the year ended December 31, 2008, as compared to $8.2 million for the year ended December 31, 2007. The increase in gross profit margin percentage was primarily attributable to increased utilization and capacity at LMD, increased sales of higher gross margin assays, and changes in revenue mix between our higher and lower gross margin items. The increase in gross profit was primarily attributable to the overall increase in revenue coupled with the increase in gross margin.

Operating expenses.Research and development expenses increased to $7.8 million for the year ended December 31, 2008 from $6.4 million for the year ended December 31, 2007. The increase in research and development expenses was primarily due to incorporation of the results of LMD for the full twelve months in 2008 compared to the inclusion of only ten months of operating results of LMD in the year ended December 31, 2007, as the acquisition was consummated on March 1, 2007, and to a lesser extent, to increased activity by the Assay Segment related to product development.

42

Selling, general and administrative expenses increased to $12.1 million for the year ended December 31, 2008 from $9.6 million for the comparable period in 2007, excluding the non-recurring $7.4 million write-off of in-process research and development related to the acquisition of LMD, for the nine months ended September 30, 2007. The overall increase in selling, general, and administrative expenses is primarily due to the addition of costs associated with LMD. As previously discussed, the expenses for the year ended December 31, 2007 include expenses related to LBG for the entire twelve months and expenses related to LMD for ten months only. The overall increase in selling, general and administrative expenses was primarily attributable to the addition of LMD and to a lesser extent increased activity by the LBG.

Gain on settlement of liability.$2.3 million was recognized in the year ended December 31, 2007 related to the settlement of a liability related to the renegotiation of a contract acquired as part of the acquisition of Tm Bioscience.

	$	124,120	$	34,177

At December 31, 2008, we held cash and cash equivalents, and short-term and long-term investments, of $124.1 million and had working capital of $131.5 million. At December 31, 2007, we held cash and cash equivalents, and short-term and long-term investments, of $34.2 million and had working capital of $40.8 million. Cash, cash equivalents and investments have increased by approximately $89.9 million during the year ended December 31, 2008 due primarily to the cash proceeds from our secondary public offering in June of 2008 of $74.7 million and cash provided from operations of $13.9 million.

We have funded our operations to date primarily through the issuance of equity securities (in conjunction with an initial public offering in 2000, subsequent option exercises, and our secondary public offering in 2008) and cash generated from operations. Our cash reserves are held directly or indirectly in a variety of short-term, interest-bearing instruments, including obligations of the United States government or agencies thereof and United States corporate debt securities. We do not have any investments in asset-backed commercial paper, auction rate securities, or mortgage backed or sub-prime style investments.

Cash provided by operations was $13.9 million for the year ended December 31, 2008. Significant items affecting operating cash flows for the period were our net income of $3.1 million and adjustments for depreciation and amortization of $7.0 million and stock compensation of $7.3 million, offset by an increase in inventory of $5.1 million. Other income decreased due to expenditures of approximately $481,000 in the year ended December 31, 2008 related to a potential acquisition that did not occur, and were consequently reflected as an investing activity rather than an operating activity.

Our operating expenses during the year ended December 31, 2008 were $67.6 million, of which $18.6 million was research and development expense and $49.0 million was selling, general and administrative expense. While research and development expense as a percentage of revenue decreased in 2008 to 18% from 21% in 2007 and is expected to continue to decrease, we expect the absolute dollars of research and development expense to scale with our revenue growth as a result of our continuing investment in the research and development pipeline to support our strategy and expanded focus on product and platform development. We currently expect selling, general, and administrative expenses in 2009, excluding the impact of foreign exchange rates on foreign denominated balances, to decrease as a percentage of total revenue compared to 47% in 2008.

43

Cash used in investing activities was $41.7 million for the year ended December 31, 2008 as compared with cash provided by investing of $1.8 million for the year ended December 31, 2007. In 2008, our purchases of securities increased $49.5 million due to our investment of the cash proceeds from our secondary public offering. Capital expenditures for property, plant and equipment decreased to $4.5 million from $6.7 million in 2007, primarily from the completion of our manufacturing expansion in 2007 in preparation for the introduction of new products, expansion of capacity, and facility and enterprise resource planning expansion to accommodate our growth and the Assay Segment operations. Currently, exclusive of changes in investments, we expect cash used in investing activities to be primarily for purchases of property, plant and equipment.

Cash provided by financing activities was $81.7 million for the year ended December 31, 2008 as compared with cash used in financing activities of $10.5 million for the year ended December 31, 2007 due to our secondary public offering in June of 2008 of $74.7 million and proceeds from issuance of common stock due to exercises of stock options and warrants of $7.0 million in 2008 compared to $1.9 million in 2007.

We expect research and development expense as a percent of revenue to be between 15% and 18% of total revenue in 2009. While the percentage is expected to decrease, we expect research and development expenses in absolute dollars to scale with our revenue growth as a result of our continuing investment in the research and development pipeline to support our strategy and expanded focus on product and platform development. We expect selling, general and administrative expenses in 2009, excluding the impact of foreign exchange on foreign denominated balances, to decrease as a percentage of total revenue as in the prior year as management believes it can leverage the current level of expenses to adequately support the ongoing growth of our business.

Our future capital requirements will depend on a number of factors, including our success in developing and expanding markets for our products, payments under possible future strategic arrangements, continued progress of our research and development of potential products, the timing and outcome of regulatory approvals, the need to acquire licenses to new technology, costs associated with strategic acquisitions including integration costs and assumed liabilities, litigation expense, the status of competitive products and potential cost associated with both protecting and defending our intellectual property. Additionally, actions taken as a result of the ongoing internal evaluation of our business could result in expenditures not currently contemplated in our estimates for 2009. We believe, however, that our existing cash and cash equivalents are sufficient to fund our operating expenses, capital equipment requirements and other expected liquidity requirements for the coming twelve months. Based upon our current operating plan and structure, management believes Luminex will have sufficient capital to fund operations through December 31, 2009. Factors that could affect our capital requirements, in addition to those listed above, include: (i) continued collections of accounts receivable consistent with our historical experience, (ii) our ability to manage our inventory levels consistent with past practices, and (iii) signing of partnership agreements which include significant up front license fees. See also the “Safe Harbor Cautionary Statement” and Item 1A “Risk Factors” above.

On March 1, 2007, we entered into a senior revolving credit facility with JPMorgan Chase Bank, N.A., which provided borrowings of up to a maximum aggregate principal amount outstanding of $15.0 million based on availability under a borrowing base consisting of eligible accounts and inventory. The obligations under the senior revolving credit facility were guaranteed by our wholly-owned domestic subsidiaries and secured by all of our and the guarantors’ accounts, equipment inventory and general intangibles (excluding intellectual property), and the guarantors including the pledge of an intercompany note from LMD and payable to Luminex. Loans under the senior credit facility accrued interest on the basis of either a base rate or a LIBOR rate. The base rate was calculated daily and was the greater of (i) prime minus 1.00% and (ii) federal funds rate plus .50%. Borrowings at the LIBOR rate were based on one, two or three month periods and interest was calculated by taking the sum of (i) the product of LIBOR for such period and statutory reserves plus (ii) 1.75%. We paid a fee of 0.125% per annum on the unfunded portion of the lender’s aggregate commitment under the facility. As of December 31, 2008, no amounts were outstanding under the senior revolving credit facility, and approximately $10.4 million was available for borrowing. This credit facility had a maturity of February 26, 2009. We elected not to renew this credit facility given our significant cash, cash equivalents, and investment balance and in light of our projected capital needs for the foreseeable future.

44

The senior credit facility contained conditions to making loans, representations, warranties and covenants, including financial covenants customary for a transaction of this type. Financial covenants included (i) a tangible net worth covenant of $35.0 million and (ii) a liquidity requirement of availability not less than the funded debt of Luminex and its subsidiaries calculated using the unencumbered cash, cash equivalents and marketable securities of us and our guarantors (including LMD). The senior credit facility also contained customary events of default as well as restrictions on undertaking certain specified corporate actions, including, among others, asset dispositions, acquisitions and other investments, dividends, fundamental corporate changes such as mergers and consolidations, incurrence of additional indebtedness, creation of liens and negative pledges, transactions with affiliates and agreements as to certain subsidiary restrictions and the creation of additional subsidiaries. If an event of default occurred that was not otherwise waived or cured, the lender may have terminated its obligations to make loans under the senior credit facility and may have declared the loans then outstanding under the senior credit facility to be due and payable. We believe we were in compliance with our financial and other covenants under the senior credit facility.

To the extent our capital resources are insufficient to meet future capital requirements we will have to raise additional funds to continue the development and deployment of our technologies. There can be no assurance that debt or equity funds will be available on favorable terms, if at all, particularly given the current state of the capital markets. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of those securities could result in dilution to our stockholders. Moreover, incurring debt financing could result in a substantial portion of our operating cash flow being dedicated to the payment of principal and interest on such indebtedness, could render us more vulnerable to competitive pressures and economic downturns and could impose restrictions on our operations. If adequate funds are not available, we may be required to curtail operations significantly or to obtain funds through entering into agreements on unattractive terms.

45

Contractual Obligations

As of December 31, 2008, we had approximately $7.4 million in non-cancelable obligations for the next 12 months. These obligations are included in our estimated cash usage during 2009. The following table reflects our total current non-cancelable obligations by period as of December 31, 2008 (in thousands):

	Payments Due By Period
			Less Than						More Than
Contractual Obligations	Total		1 Year		1-3 Years		3-5 Years		5 Years
Non-cancelable rental obligations	$	10,931	$	1,966	$	3,468	$	3,550	$	1,947
Non-cancelable purchase obligations(1)		10,050		4,946		1,573		1,299		2,232
Long-term debt obligations(2)		4,485		445		1,617		2,423		—
Capital lease obligations		47		29		18		—		—
Total(3)	$	25,513	$	7,386	$	6,676	$	7,272	$	4,179

(1)	Purchase obligations include contractual arrangements in the form of purchase orders primarily as a result of normal inventory purchases or minimum payments due resulting when minimum purchase commitments are not met.
(2)	On December 12, 2003, LMD entered into an agreement with the Ministry of Industry of the Government of Canada under which the Government agreed to invest up to Canadian (Cdn) $7.3 million relating to the development of several genetic tests. Funds were advanced from Technology Partnerships Canada (TPC), a special operating program. The actual payments we received were predicated on eligible expenditures made during the project period which ended July 31, 2006. LMD has received Cdn $4.3 million from TPC which is expected to be repaid along with approximately Cdn $1.4 million of imputed interest for a total of approximately Cdn $5.7 million.
	LMD has agreed to repay the TPC funding through a royalty on revenues. Royalty payments commenced in 2007 at a rate of 1% of total revenue and at a rate of 2.5% for 2008 and thereafter. Aggregate royalty repayment will continue until total advances plus imputed interest has been repaid or until April 30, 2015, whichever is earlier. The repayment obligation expires on April 30, 2015 and any unpaid balance will be cancelled and forgiven on that date. Should the term of repayment be shorter than expected due to higher than expected assay revenue, the effective interest rate would increase as repayment is accelerated. Repayments denominated in U.S. Dollars are currently projected to be as shown in the table above, but actual future sales generating a repayment obligation will vary from this projection and are subject to the risks and uncertainties described elsewhere in this report, including under “Risk Factors” and “Safe Harbor Cautionary Statement.” Furthermore, payment reflected in U.S. Dollars is subject to adjustment based upon applicable exchange rates as of the reporting date.
(3)	Due to the uncertainty with respect to the timing of future cash flows associated with Luminex’s unrecognized tax benefits at December 31, 2008, Luminex is unable to make reasonably reliable estimates of the timing of cash settlement with the respective taxing authority. Therefore, $251,000 of unrecognized tax benefits have been excluded from the contractual obligations table above. See Note 10 to the Consolidated Financial Statements for a discussion on income taxes.

Inflation

We do not believe that inflation has had a direct adverse effect on our operations to date. However, a substantial increase in product and manufacturing costs and personnel related expenses could have an adverse impact on our results of operations in the event these expenses increase at a faster pace than we can increase our system, consumable and royalty rates.

46

Recently Adopted Accounting Standards

In June 2006, the Financial Accounting Standards Board (FASB) issued FASB Interpretation (FIN) 48, “Accounting for Uncertainty in Income Taxes”. FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements in accordance with SFAS 109, “Accounting for Income Taxes”. This Interpretation defines the minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. We adopted FIN 48 as of January 1, 2007. See Note 10 to our Notes to Consolidate Financial Statements.

Recent Accounting Pronouncements

In September 2006, the FASB issued FAS No. 157, “Fair Value Measurements” (FAS 157). FAS 157 provides enhanced guidance for using fair value to measure assets and liabilities. It does not require any new fair value measurements, but does require expanded disclosures to provide information about the extent to which fair value is used to measure assets and liabilities, the methods and assumptions used to measure fair value, and the effect of fair value measures on earnings. FAS 157 is effective for financial assets and financial liabilities for fiscal years beginning after November 15, 2007. In February 2008, the FASB issued FASB Staff Position FAS 157-2, “Effective Date of FASB Statement No. 157” (FSP). The FSP delayed, for one year, the effective date of FAS 157 for all nonfinancial assets and liabilities, except those that are recognized or disclosed in the financial statements on at least an annual basis. The implementation of FAS 157 for financial assets and financial liabilities, effective January 1, 2008, did not have a material impact on our consolidated financial position and results of operations. We have disclosed the fair value of our debt in Note 11. We are currently assessing the impact of FAS 157 for nonfinancial assets and nonfinancial liabilities on our consolidated financial position and results of operations.

In October 2008, the FASB issued FAS 157-3,Determining the Fair Value of a Financial Asset When the Market for That Asset Is Not Active(FAS 157-3). FAS 157-3 clarifies the application of FASB Statement No. 157,Fair Value Measurements, in a market that is not active and provides an example to illustrate key considerations in determining the fair value of a financial asset when the market for that financial asset is not active. The FSP is effective upon issuance, including for prior periods for which financial statements have not been issued. Revisions resulting from a change in the valuation technique or its application should be accounted for as a change in accounting estimate following the guidance in FASB Statement No. 154,Accounting Changes and Error Corrections. However, the disclosure provisions in Statement 154 for a change in accounting estimate are not required for revisions resulting from a change in valuation technique or its application. We believe the impact of this pronouncement on our consolidated financial statements to be immaterial.

In February 2007, the FASB issued FAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities — Including an amendment of FASB Statement No. 115” (FAS 159). FAS 159 permits entities to choose to measure many financial assets and financial liabilities at fair value. Unrealized gains and losses on items for which the fair value option has been elected are reported in earnings. FAS 159 is effective for fiscal years beginning after November 15, 2007. The implementation of this standard did not have a material impact on our consolidated financial position and results of operations.

In December 2007, the FASB issued FAS No. 141 (Revised 2007), “Business Combinations”(FAS 141R) which replaces FAS No. 141, “Business Combinations” and FAS No. 160, “Noncontrolling Interests in Consolidated Financial Statements” (FAS 160). FAS 141R establishes principles and requirements for how an acquirer recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, any noncontrolling interest in the acquiree and the goodwill acquired. FAS 141R also establishes disclosure requirements that will enable users to evaluate the nature and financial effects of the business combination. FAS 160 clarifies the classification of noncontrolling interests in the financial statements and the accounting for and reporting of transactions between the reporting entity and holders of such noncontrolling interests. FAS 141R and FAS 160 are effective for our fiscal year 2009 and must be applied prospectively to all new acquisitions closing on or after January 1, 2009. Upon adoption, these standards will not have a material impact on our consolidated financial position and results of operations. However, if we enter into any business combinations after the adoption of FAS 141R, a transaction may significantly impact our consolidated financial position and results of operations as compared to our recent Tm Bioscience acquisition, accounted for under existing GAAP requirements, due to the changes described above.

47

In April 2008, the FASB issued FSP FAS No. 142-3, “Determination of the Useful Life of Intangible Assets” (FSP FAS 142-3). FSP FAS 142-3 amends the factors that should be considered in developing renewal or extension assumptions used to determine the useful life of a recognized intangible asset under FASB Statement No. 142, “Goodwill and Other Intangible Assets”. FSP FAS 142-3 is effective for financial statements issued for fiscal years beginning after December 15, 2008, and interim periods within those fiscal years. Early adoption is prohibited. Based on our current operations, we do not expect that the adoption of FSP FAS 142-3 will have a material impact on our consolidated financial position or results of operations.

In May 2008, the FASB issued FAS No. 162,The Hierarchy of Generally Accepted Accounting Principles(FAS 162). FAS 162 identifies the sources of accounting principles and the framework for selecting the principles used in the preparation of financial statements of nongovernmental entities that are presented in conformity with generally accepted accounting principles in the United States (the GAAP hierarchy). FAS 162 will become effective 60 days following the SEC’s approval of the Public Company Accounting Oversight Board amendments to AU Section 411,The Meaning of Present Fairly in Conformity With Generally Accepted Accounting Principles. Based on our current operations, we do not expect this standard will have a material impact on our financial position or results of operations.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk.Our interest income is sensitive to changes in the general level of domestic interest rates, particularly since our investments are in short-term and long-term instruments held to maturity. A 50 basis point fluctuation from average investment returns at December 31, 2008 would yield an approximate 4% variance in overall investment return. Due to our intention to hold our investments to maturity, we have concluded that there is no material market risk exposure.

Our revolving credit facility also would have been affected by fluctuations in interest rates as it is based on prime minus 1% or the Federal Funds Effective Rate in effect plus 0.50%. As of December 31, 2008, we had not drawn on this facility. We elected not to renew this credit facility on February 26, 2009.

Foreign Currency Risk.As of December 31, 2008, as a result of our foreign operations, we have costs, assets and liabilities that are denominated in foreign currencies, primarily Canadian dollars and to a lesser extent the Euro. For example, some fixed asset purchases, certain expenses, and the TPC debt of our Canadian subsidiary, LMD, are denominated in Canadian dollars while sales of products are primarily denominated in U.S. dollars. All transactions in our Netherlands subsidiary are denominated in Euros. As a consequence, movements in exchange rates could cause our foreign currency denominated expenses to fluctuate as a percentage of net revenue, affecting our profitability and cash flows. A significant majority of our revenues are denominated in U.S. dollars. The impact of foreign exchange on foreign denominated balances will vary in relation to changes between the U.S. and Canadian Dollar exchange rates. A 10% change in the Canadian Dollar in relation to the U.S. dollar could result in an immaterial foreign exchange impact. As a result of our efforts to expand globally, in the future we will be exposed to additional foreign currency risk in multiple currencies; however, at this time, our exposure to foreign currency fluctuations is not material.

In addition, the indirect effect of fluctuations in interest rates and foreign currency exchange rates could have a material adverse effect on our business financial condition and results of operations. For example, currency exchange rate fluctuations could affect international demand for our products. In addition, interest rates fluctuations could affect our customers’ buying patterns. Furthermore, interest rate and currency exchange rate fluctuations may broadly influence the United States and foreign economies resulting in a material adverse effect on our business, financial condition and results of operations. As a result, we cannot give any assurance as to the effect that future changes in foreign currency rates will have on our consolidated financial position, results of operations or cash flows. Our aggregate foreign currency transaction loss of $465,000 was included in determining our consolidated results for the year ended December 31, 2008.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders
of Luminex Corporation

We have audited Luminex Corporation’s internal control over financial reporting as of December 31, 2008, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Luminex Corporation’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 included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

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, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, 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, Luminex Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2008, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Luminex Corporation as of December 31, 2008 and 2007, and the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2008 of Luminex Corporation and our report dated February 24, 2009 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders of
Luminex Corporation

We have audited the accompanying consolidated balance sheets of Luminex Corporation (the Company) as of December 31, 2008 and 2007, and the related consolidated statements of operations, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2008. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with 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 Luminex Corporation at December 31, 2008 and 2007 and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2008, in conformity with U.S. generally accepted accounting principles.

As discussed in Note 1 to the financial statements, in 2007 the Company changed its method of accounting for income tax uncertainties.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company’s internal control over financial reporting as of December 31, 2008, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 24, 2009 expressed an unqualified opinion thereon.

LUMINEX CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 — DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Business

Luminex Corporation (the “Company” or “Luminex”) develops, manufactures and sells proprietary biological testing technologies and products with applications throughout the life sciences and diagnostic industries. The Company’s xMAP^® technology, an open architecture, multiplexing technology, allows the Luminex systems to simultaneously perform up to 100 bioassays on a single drop of fluid by reading biological tests on the surface of microscopic polystyrene beads called microspheres. xMAP technology combines this miniaturized liquid array bioassay capability with small lasers, digital signal processors and proprietary software to create a system offering advantages in speed, precision, flexibility and cost. The Company’s xMAP technology is currently being used within various segments of the life sciences industry which includes the fields of drug discovery and development, clinical diagnostics, genetic analysis, bio-defense, protein analysis and biomedical research.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany transactions and balances have been eliminated upon consolidation.

The acquisition of Tm Bioscience Corporation, or Tm, now known as Luminex Molecular Diagnostics, Inc., or LMD, was completed on March 1, 2007; therefore, the results of operations of LMD in our consolidated financial statements only include LMD results since that date.

Use of Estimates

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 amounts reported in the financial statements and accompanying notes. Actual amounts and results could differ from those estimates, and such differences could be material to the financial statements.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash deposits and investments with original maturities of three months or less when purchased.

Investments

The Company’s investments are classified as held-to-maturity since the Company has the intent and ability to hold the securities to maturity. Held-to-maturity securities are stated at cost, adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization is included in other income. Interest on securities classified as held-to-maturity is also included in other income.

Fair Value of Financial Instruments

The fair values of financial instruments are determined based on quoted market prices and market interest rates as of the end of the reporting period. Our financial instruments include cash and cash equivalents, short-term investments, accounts receivable, long-term investments, accounts payable, accrued liabilities, and long-term debt. Except for the fair value of our long-term debt, the fair values of these financial instruments were not materially different from their carrying or contract values at December 31, 2008 and 2007. See Note 11 for further details concerning the fair value of our long-term debt.

57

Concentration of Credit Risk

Financial instruments which potentially subject the Company to concentrations of credit risk consist of short-term investments and trade receivables. The Company’s short-term investments consist of investments in high credit quality financial institutions and corporate issuers.

The Company provides credit, in the normal course of business, to a number of its customers geographically dispersed primarily throughout the U.S. The Company attempts to limit its credit risk by performing ongoing credit evaluations of its customers and maintaining adequate allowances for potential credit losses and does not require collateral.

In 2008, two customers each accounted for more than 10% of our total revenues. One Lambda, Inc. accounted for 19%, 15% and 15% of our total revenues in 2008, 2007 and 2006, respectively. Bio-Rad Laboratories, Inc. accounted for 17%, 20% and 19% of our total revenues in 2008, 2007 and 2006, respectively. No other customer accounted for more than 10% of total revenues in 2008, 2007 or 2006.

Inventories

Inventories, consisting primarily of raw materials and purchased components, are stated at the lower of cost or market. The Company routinely assesses its on-hand inventory for timely identification and measurement of obsolete, slow-moving or otherwise impaired inventory.

Property and Equipment

Property and equipment are carried at cost less accumulated amounts for amortization and depreciation. Property and equipment are generally amortized or depreciated on a straight-line basis over the useful lives of the assets, which range from two to seven years. Leasehold improvements and equipment under capital lease are amortized on a straight-line basis over the shorter of the remaining term of the lease or the estimated useful life of the improvements and equipment. The Company classifies the carrying value of Luminex xMAP™ Instruments placed within the reagent rental program and the instruments on loan to customers in Property and equipment as “Assets on loan/rental”.

Intangible Assets

Goodwill represents the excess of the cost over the fair value of the assets of the acquired business. Goodwill is reviewed for impairment at least annually at the beginning of the fourth quarter. No goodwill impairments were recorded in 2008 or 2007. Intangible assets are amortized on a straight line basis over their respective estimated useful lives ranging from 2 to 15 years. The useful lives of the assets acquired as part of the Tm acquisition were established as a result of the allocation of fair values at March 1, 2007. We have no intangible assets with indefinite useful lives.

Impairment of Long-Lived Assets

Long-lived assets held and used by the Company are reviewed for impairment whenever events or changes in circumstances indicate that their net book value may not be recoverable. When such factors and circumstances exist, the Company compares the projected undiscounted future cash flows associated with the related asset or group of assets over their estimated useful lives against their respective carrying amounts. Impairment, if any, is based on the excess of the carrying amount over the fair value of those assets and is recorded in the period in which the determination was made.

58

Revenue Recognition and Allowance For Doubtful Accounts

Revenue from sales of the Company’s products is recognized when persuasive evidence of an agreement exists, delivery of the product has occurred, the fee is fixed and determinable and collectability is probable. Generally, these criteria are met at the time the product is shipped. If the criteria for revenue recognition are not met at the time of shipment, the revenue is deferred until all criteria are met. Revenues from royalties related to agreements with strategic partners are recognized when such amounts are reported to the Company; therefore, the underlying end-user sales may be related to prior periods. Revenue from extended service agreements is deferred and recognized ratably over the term of the agreement. Revenues from contracts with multiple elements are recognized as each element is earned based on the relative fair value of each element when there are no undelivered elements that are essential to the functionality of the delivered elements and when the amount is not contingent upon delivery of the undelivered elements. Amounts billed or collected in excess of revenue recognized are recorded as deferred revenue.

We continuously monitor collections and payments from our customers and maintain allowances for doubtful accounts based upon our historical experience and any specific customer collection issues that have been identified. While such credit losses have historically been within our expectations, there can be no assurance that we will continue to experience the same level of credit losses that we have in the past. A significant change in the liquidity or financial position of any one of our significant customers, or a deterioration in the economic environment, in general, could have a material adverse impact on the collectability of our accounts receivable and our future operating results, including a reduction in future revenues and additional allowances for doubtful accounts.

Product-Related Expenses

We provide for the estimated cost of initial product warranties at the time revenue is recognized. While we engage in product quality programs and processes, our warranty obligation is affected by product failure rates, material usage and service delivery costs incurred in correcting a product failure. Should actual product failure rates, material usage or service delivery costs differ from our estimates, revisions to the estimated warranty liability would be required. Shipping and handling costs associated with product sales are included in cost of sales. The Company expenses advertising costs as incurred. Advertising expenses were not significant for any of the years presented.

Research and Development Costs

Research and development costs are generally expensed in the period incurred; however, the Company capitalizes certain internally developed products, used for evaluation during development projects that also have alternative future uses as defined by SFAS 2, “Accounting for Research and Development Costs”. These assets are generally depreciated on a straight-line basis over the useful life of the assets which range from two months to one year. The Company did not capitalize any material research and development costs in 2008 or 2007.

Incentive Compensation

Management incentive plans are tied to various financial and non-financial performance metrics. Bonus accruals made throughout the year related to the various incentive plans are based on management’s best estimate of the achievement of the specific metrics. Adjustments to the accruals are made on a quarterly basis as forecasts of performance are updated. At year-end, the accruals are adjusted to reflect the actual results achieved.

Income Taxes

The Company accounts for income taxes in accordance with SFAS No. 109, Accounting for Income Taxes, under the asset and liability method.  Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases.  Deferred tax balances are adjusted to reflect tax rates based on currently enacted tax laws, which will be in effect in the years in which the temporary differences are expected to reverse.  The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the results of operations in the period of the enactment date. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets unless it is more likely than not that such assets will be realized.

59

Effective January 1, 2007, the Company adopted FASB Interpretation (FIN) No. 48, “Accounting for Uncertainty in Income Taxes — an interpretation of FASB Statement No. 109”, which clarifies the accounting for uncertainty in tax positions. FIN No. 48 requires recognition of the impact of a tax position in the Company’s financial statements only if that position is more likely than not of being sustained upon examination by taxing authorities, based on the technical merits of the position. Any interest and penalties related to uncertain tax positions will be reflected in income tax expense.

Earnings Per Share

Basic net income (loss) per share is computed by dividing the net income (loss) for the period by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed by dividing the net income (loss) for the period by the weighted average number of common and common equivalent shares outstanding during the period. Potentially dilutive securities composed of incremental common shares issuable upon the exercise of stock options and warrants, and common shares issuable on conversion of preferred stock, were excluded from historical diluted loss per share because of their anti-dilutive effect.

Stock-Based Compensation

The Company accounts for stock-based employee compensation plans under the fair value recognition and measurement provisions of SFAS No. 123(R). SFAS No. 123(R) requires the recognition of compensation expense, using a fair-value based method, for costs related to all share-based payments including stock options. Pursuant to SFAS No. 123(R), stock-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as expense over the requisite service period.

Segment Reporting

Historically the Company had operated as a single segment. Subsequent to the acquisition of LMD, management determined that we have two segments for financial reporting purposes: the Technology Segment and the Assay Segment. See Note 17 — Segment and Geographic Information.

60

NOTE 2 — BUSINESS COMBINATIONS

Acquisition

On March 1, 2007, the Company completed the acquisition of Tm, a DNA-based research and diagnostics company headquartered in Toronto, Canada. Prior to the acquisition, Tm was one of our strategic partners. All intercompany balances were eliminated upon acquisition. We believe this acquisition is a logical extension of our strategy and that the combined Company will be in a position to take advantage of the complementary strengths of both companies in molecular diagnostics. The acquired company is referred to as LMD and is included in our Assay Segment for financial reporting purposes. The focus of LMD is to design, develop, manufacture and commercialize nucleic-acid based testing products for use in the genetic testing, personalized medicine and infectious disease markets.

Upon the closing of the acquisition, we exchanged 0.06 shares of Luminex common stock for each outstanding Tm share, which resulted in the issuance of approximately 3.2 million shares of Luminex common stock. The value of the approximately 3.2 million common shares issued was determined based on the average market price of our common stock over the period including five days before and after the terms of the acquisition were agreed to and announced in accordance with SFAS No. 141, “Business Combinations” (“SFAS 141”). We also agreed to assume the outstanding Tm options according to the applicable Tm plan provisions and the outstanding warrants. At the date of acquisition, these options and warrants were potentially exercisable for approximately 694,000 additional shares of Luminex common stock on an as-converted basis. The estimated fair value of Luminex’ replacement options and warrants was calculated using the Black-Scholes model. In accordance with SFAS 123R, the portion of the estimated fair value of unvested Tm options related to future service (approximately $242,000) was deducted from the purchase price consideration and will be recognized as compensation expense over those awards’ remaining vesting period. As of December 31, 2008, there were replacement options outstanding for the purchase of 68,414 shares of Luminex common stock with exercise prices ranging from $11.12 to $44.88 and replacement warrants outstanding for the purchase of approximately 288,000 shares of Luminex common stock with exercise prices ranging from $10.12 to $37.18. All of the warrants are exercisable as of December 31, 2008.

Immediately subsequent to the acquisition, we retired approximately $13.2 million of Tm debt, including an approximately $1.0 million contractual penalty, by using existing cash reserves. Under the terms of one of the retired debt instruments, the balance of the note became callable upon the acquisition and was subject to a contractual penalty if either called by the debt holder or prepaid by Tm. The penalty was triggered when the Tm shareholders ratified the acquisition of Tm by Luminex on February 21, 2007. The penalty was recorded by Tm prior to Luminex’ acquisition based on the penalty amount agreed by the debt holder, and was reflected in the opening balance of “Other current liabilities assumed.”

The acquisition was accounted for as a purchase business combination in accordance with SFAS 141. LMD results of operations are included with the Company’s from the date of acquisition, March 1, 2007. The purchase price of the acquisition was approximately $49.4 million, including the issuance of common stock valued at $41.8 million and transaction costs of approximately $3.6 million. The purchase price has been allocated to the net assets acquired based on estimates of the fair values at the date of the acquisition.

In 2007, Luminex completed the process of allocating fair values for certain tangible and intangible assets and in-process research and development (IPR&D) identified during the acquisition. The acquired intangible assets were allocated to the Assay Segment. The excess purchase price over the fair values of the net tangible assets, identified intangible assets and liabilities was allocated to goodwill. Luminex recorded $39.6 million of goodwill related to the Tm acquisition in our Assay Segment. Goodwill is not expected to be deductible for tax purposes.

61

The following table summarizes the estimated fair values of net assets at the date of acquisition (in thousands). Certain tangible and intangible assets and liabilities were adjusted to their estimated fair market values upon the final analysis of these values during the fourth quarter. Based on SFAS 141, the following intangible assets evaluated were: trade name (Tag-It), customer list/contracts, technology/trade secrets, and in-process research and development. IPR&D has been recorded at its estimated fair market value and charged to expense in 2007.

Pro Forma Information

The financial information in the table below summarizes the combined results of operations of Luminex and LMD, on a pro forma basis, as though the companies had been combined at the beginning of 2006.

The pro forma financial information is presented for informational purposes only and is not indicative of the results of operation that would have been achieved if the acquisition of LMD had taken place at the beginning of fiscal 2006.

The following table summarizes the pro forma financial information for the years ended December 31, 2007 and 2006 (in thousands, except per share amounts):

	Year Ended
	December 31,
	2007			2006
Revenues	$	75,328		$	60,361
Net loss	$	(8,488	)	$	(17,792	)
Net loss per share, basic and diluted	$	(0.25	)	$	(0.51	)

In-process Research and Development (IPR&D)

In conjunction with the acquisition of LMD in 2007, the Company has recorded total IPR&D expense of $7.4 million for acquired IPR&D which was not technologically feasible as of the acquisition date and had no alternative future use.

62

NOTE 3 — INVESTMENTS

Held-to-maturity securities as of December 31, 2008 and 2007 consisted of $42.5 million and $6.9 million of federal agency debt securities, respectively. Amortized cost approximates fair value of these investments.

The amortized cost of held-to-maturity debt securities at December 31, 2008 and 2007, by contractual maturity, are shown below (in thousands). Expected maturities may differ from contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties.

	December 31,
	2008						2007
			Accrued		Amortized				Accrued		Amortized
	Cost		Interest		Cost		Cost		Interest		Cost
Due in one year or less	$	40,501	$	283	$	40,784	$	6,944	$	38	$	6,982

	$	42,501	$	303	$	42,804	$	6,944	$	38	$	6,982

SFAS 157 defines fair value, establishes a framework for measuring fair value under generally accepted accounting principles and enhances disclosures about fair value measurements. Fair value is defined under SFAS 157 as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value under SFAS 157 must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following:

Level 1—Quoted prices in active markets for identical assets or liabilities.

Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

63

In accordance with SFAS 157, the following table represents the Company’s fair value hierarchy for its financial assets (cash equivalents and investments) measured at fair value on a recurring basis as of December 31, 2008 (in thousands):

NOTE 9 — ACCRUED WARRANTY COSTS

Sales of certain of the Company’s systems are subject to a warranty. System warranties typically extend for a period of twelve months from the date of installation or no more than 15 months from the date of shipment. The Company estimates the amount of warranty claims on sold products that may be incurred based on current and historical data. The actual warranty expense could differ from the estimates made by the Company based on product performance. Warranty expenses are evaluated and adjusted periodically.

The following table summarizes the changes in the warranty accrual (in thousands):

As of December 31, 2008, the Company had U.S. federal net operating loss carryforwards of approximately $75.4 million and research and development credit carryforwards of approximately $2.9 million that will expire in fiscal years 2013 through 2028. We have net operating losses in various states that total $14.3 million. The state net operating loss carryforwards expire in fiscal years 2009 through 2021. In addition, the Company has Canadian non-capital income tax loss carryforwards of $28.0 million, a scientific research and experimental development pool in Canada of $25.3 million, and investment tax credits, accounting for under the deferred method, in Canada of $5.4 million that will begin to expire in 2009 if not utilized prior to that time. Utilization of the net operating losses and tax credits may be subject to substantial annual limitation due to the “change in ownership” provisions of the Internal Revenue Code of 1986. The annual limitation may result in the expiration of net operating losses and research and development credits before utilization.

The Company establishes valuation allowances when necessary to reduce deferred tax assets to amounts expected to be realized. As of December 31, 2008, 2007 and 2006, the Company recorded a valuation allowance of $58.6 million, $62 million, and $39.7 million, respectively. The decrease of $3.4 million in 2008 is due primarily to the earnings generated in the United States. The increase in 2007 of $22.3 million is due primarily to the acquisition of Tm Bioscience as discussed in Note 2. In the years ended December 31, 2008 and 2007, cash paid for taxes, net of cash received for tax refunds, was approximately $405,000 and $226,000, respectively.

68

Undistributed earnings of our foreign subsidiary of approximately $803,000 are considered permanently reinvested and, accordingly, no provision for U.S. federal or state income taxes has been provided thereon. It is not practical to determine the deferred tax liability on these undistributed earnings.

The Company’s provision (benefit) for income taxes attributable to continuing operations differs from the expected tax expense (benefit) amount computed by applying the statutory federal income tax rate to income before income taxes as a result of the following:

	Year Ended December 31,
	2008			2007			2006
Statutory tax rate		35.0	%		34.0	%		34.0	%

Luminex adopted FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes (“FIN 48”) on January 1, 2007. FIN 48 clarifies the accounting for and disclosure of uncertainty in tax positions and provides guidance on the recognition, measurement, derecognition, classification, and disclosure of tax positions and on the accounting for related interest and penalties. As a result of the adoption of FIN 48, we recognize accrued interest and penalties related to unrecognized tax benefits as a component of income tax expense. Although the adoption of this standard has not had a significant impact on the Company’s tax provision thus far, the recognition of tax uncertainties through earnings in the future could be materially impacted by this new accounting policy.

The adoption of FIN 48 resulted in no impact to either the Company’s reserves for uncertain tax positions or to retained earnings. At the adoption date, the Company had no gross unrecognized tax benefits. As of December 31, 2008, the Company had gross unrecognized tax benefits of $251,000. All of the unrecognized tax benefits, if recognized, would affect the effective tax rate. The Company does not expect or anticipate a significant increase or decrease over the next twelve months in the unrecognized tax benefits.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):

Balance at January 1, 2008	$	—
Additions based on tax positions related to the current year		—
Additions for tax positions of prior years		251

The Company or one of its subsidiaries files income tax returns in the U.S. federal jurisdiction, Canada and various states. Due to net operating losses, the statute of limitations in the US is open back to 1996. With respect to Canada, tax returns dating back to 2003 can still be reviewed by the authorities.

69

The Company recognizes accrued interest and penalties related to unrecognized tax benefits in its income tax expense. At the date of adoption, the Company had accrued no interest expense and penalties related to uncertain tax positions. During the years ended December 31, 2008 and 2007, the Company recognized approximately $23,000 and $1,000 in tax related interest and penalties, respectively.

NOTE 11 — LONG-TERM DEBT

On December 31, 2008, long-term debt consisted of a loan payable to Technology Partnership Canada (“TPC”) valued at $2.9 million and the related short term interest payable of $445,000.

On December 12, 2003, Tm entered into an agreement with the Ministry of Industry of the Government of Canada under which the Government agreed to invest up to Canadian (“Cdn”) $7.3 million relating to the development of several genetic tests. Funds were advanced from Technology Partnerships Canada (“TPC”), a special operating program. The actual payments received by the Company were predicated on eligible expenditures made during the project period which ended July 31, 2006. As of December 31, 2008, the Company had received $3.5 million from TPC ($4.3 million in Canadian dollars) which is expected to be repaid along with approximately $1.2 million of imputed interest for a total of approximately $4.7 million ($5.7 million in Canadian dollars). Approximately $208,000 ($255,000 in Canadian dollars) of the interest has been repaid as of December 31, 2008.

Tm agreed to repay the TPC funding through a royalty on revenues. This liability was assumed by the Company as part of the acquisition and the liability was recorded at fair value as of the date of acquisition. This liability is subject to adjustments for foreign currency translation effects as it is a foreign currency denominated balance. Royalty payments commenced in 2007 at a rate of 1% of total revenue and at a rate of 2.5% for 2008 and thereafter. Aggregate royalty repayment will continue until total advances plus imputed interest has been repaid or until April 30, 2015, whichever is earlier. The repayment obligation expires on April 30, 2015 and any unpaid balance will be cancelled and forgiven on that date. Should the term of repayment be shorter than we expect due to higher than expected assay revenue, the effective interest rate would increase as repayment is accelerated.

Estimated principal repayments on the debt for the next five years and thereafter are as follows (in thousands):

2009	$	445
2010		686
2011		931
2012		1,147

Discount	$	(155	)
Total long-term debt	$	3,359
Less: Current portion of long-term debt		(445	)
	$	2,914

In 2008 and 2007, the Company had imputed interest expense related to its long-term debt of $221,000 and $201,000, respectively. The effective interest rate was 4.88% and 6.65% as of December 31, 2008 and 2007, respectively. At December 31, 2008 and 2007, the fair value of our long-term debt was approximately $3.0 million and $2.9 million, respectively. Our long-term debt is classified as a Level 3 instrument and we have used a discounted cash flow (“DCF”) model to determine the estimated fair value as of December 31, 2008 and 2007. The assumptions used in preparing the DCF model include estimates for (i) the amount and timing of future interest and principal payments and (ii) the rate of return indicative of the investment risk in the ownership of the TPC debt. In making these assumptions, we considered relevant factors including the likely timing of principal repayments and the probability of full repayment considering the timing of royalty payments based upon total revenue.

Restricted stock awards (RSAs) and stock options to acquire 623,000, 1.1 million, and 658,000 shares for the years ended December 31, 2008, 2007 and 2006, respectively, were excluded from the computations of diluted earnings per share because the effect of including the RSAs and stock options would have been anti-dilutive.

NOTE 13 — STOCKHOLDERS’ EQUITY AND COMPREHENSIVE INCOME/ LOSS

Preferred Stock

The Company’s Board of Directors has the authority to issue up to 5,000,000 shares of preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof, including dividend rights, dividend rates, conversion rights, voting rights, terms of redemption, redemption prices, liquidation preferences and the number of shares constituting any series or the designation of such series, without further vote or action by the Company’s stockholders. At December 31, 2008 and 2007, there was no preferred stock issued and outstanding.

Stockholders’ Rights Plan

On June 20, 2001, the Company’s Board of Directors declared a dividend of one right for each outstanding share of the Company’s common stock to stockholders of record at the close of business on July 2, 2001. Each right entitles the registered holder to purchase from the Company a unit consisting of one one-hundredth of a share of Series A Junior Participating Preferred Stock, par value $0.001 per share, at a purchase price of $100 per fractional share, subject to adjustment. The rights are not currently exercisable and will become exercisable only in the event a person or group acquires beneficial ownership of 20 percent or more of common stock. The rights expire on June 20, 2011.

Comprehensive Income/Loss

The Company’s comprehensive income or loss is comprised of net income or loss and foreign currency translation. Comprehensive income for the year ended December 31, 2008 was approximately $3.0 million and comprehensive loss for the year ended December 31, 2007 was approximately $2.8 million.

NOTE 14 — EMPLOYEE BENEFIT PLANS AND STOCK-BASED COMPENSATION

Stock-Based Compensation

At December 31, 2008, the Company has two stock-based employee compensation plans pursuant to which grants may be made, the 2006 Equity Incentive Plan (the “Equity Incentive Plan”) and the 2006 Management Stock Purchase Plan (the “MSPP”) which were approved at our Annual Meeting on May 25, 2006. No further grants shall be made pursuant to the 1996 Stock Option Plan (the “1996 Plan”), the 2000 Long-Term Incentive Plan (the “2000 Plan”), the 2001 Broad-Based Stock Option Plan (the “2001 Plan”), or the Tm Bioscience Corporation Share Option Plan (the “Tm Plan”) that the Company assumed in connection with the Tm acquisition. The Tm Plan governs the former Tm options which were exchanged for options to purchase shares of Luminex common stock in connection with the acquisition.

Equity Incentive Plans

Under the Company’s Equity Incentive Plan, 1996 Plan, 2000 Plan, 2001 Plan, and the Tm Plan, certain employees, consultants and non-employee directors have been granted RSAs, restricted share units (RSUs) and options to purchase shares of common stock. The options, RSAs, and RSUs generally vest in installments over a four to five year period, and the options expire either five or ten years after the date of grant. Under the Equity Incentive Plan, certain employees, directors of, and consultants to the Company are eligible to be granted RSAs, RSUs, and options to purchase common stock. The MSPP provides for the granting of rights to defer an elected percentage of their bonus compensation through the purchase of restricted shares of the Company’s common stock, discounted by 20%, to certain officers of the Company. As of December 31, 2008, there were approximately 322,000 shares authorized for future issuance under the Company’s Equity Incentive Plan and 500,000 shares eligible for purchase, pursuant to the terms and conditions thereof, under the MSPP.

The Equity Incentive Plan, the MSPP, the 1996 Plan, the 2000 Plan, the 2001 Plan, and the Tm Plan are administered by the Compensation Committee of the Board of Directors. The Compensation Committee has the authority to determine the terms and conditions under which awards will be granted from the Equity Incentive Plan, including the number of shares, vesting schedule and term, as applicable. Any option award exercise prices, as set forth in the Equity Incentive Plan, will be equal to the fair market value on the date of grant. Under certain circumstances, the Company may repurchase previously granted RSAs and RSUs.

On March 25, 2007, the Compensation Committee approved an amendment to the restricted stock agreement, dated May 17, 2004 (the “Restricted Stock Agreement”), of our CEO, Patrick J. Balthrop. The Company and Mr. Balthrop initially entered into the Restricted Stock Agreement in connection with the hiring of Mr. Balthrop as the President and Chief Executive Officer of the Company. The Restricted Stock Agreement provided for the grant of 200,000 restricted shares, which would vest in portions based on the attainment of certain performance goals related to Company revenue, earnings and stock price. If the goals provided for in the Restricted Stock Agreement were not achieved by the end of the fifth anniversary of the date of the Restricted Stock Agreement, all non-vested shares would be forfeited. The amendment provides for the automatic vesting of all unvested restricted shares immediately prior to the fifth anniversary of the date of the Restricted Stock Agreement, to the extent any or all of the performance measures have not been previously achieved. Mr. Balthrop’s 200,000 share restricted stock award, as amended, has market, service or performance criteria for vesting of all shares. We have assumed that vesting will occur at the end of the five years based on achievement of the service criteria so all expense is being amortized straight-line over the five-year period from May 17, 2004 through 2009. Pursuant to the amendment to this award, the award was revalued to the market price on the date of amendment of $14.39. This resulted in additional expense to the Company of approximately $356,000 of which approximately $70,000 and $257,000 was recognized in 2008 and 2007, respectively.

72

In connection with the hiring of our Chief Executive Officer, the Company issued Patrick J. Balthrop a non-qualified stock option grant for the purchase of 500,000 shares of the Company’s common stock dated May 15, 2004 at an exercise price of $9.36 per share (the “Balthrop Option”). The Balthrop Option vests 25% on the first anniversary of the date of grant and ratably on a monthly basis for the three years following the initial vesting date. This award was not pursuant to any of the Company’s existing equity incentive plans. As previously reported, at a meeting of the Compensation Committee of the Board of Directors on February 10, 2005, the committee approved resolutions to increase the exercise price of the Balthrop Option from $9.36 per share to $10.10 per share (the closing market price on the date immediately preceding the original grant date). This modification was made in order to eliminate the potential application of certain adverse tax implications in light of tax law changes created as a result of the American Jobs Creation Act of 2004. In connection therewith, the Compensation Committee approved a cash bonus payable to Mr. Balthrop to be paid consistent with the vesting period of the option grant, subject to Mr. Balthrop’s continued employment, equal to $370,000. According to the vesting schedule and assuming no acceleration event contemplated by the Balthrop Option, one quarter of the cash bonus was paid as of May 15, 2005 (the first vesting date and consistent with the equity vesting) and the balance of such payments was made in equal monthly installments over the 36 months thereafter.

On December 4, 2008 the Board adopted the Luminex Corporation 2008 Long Term Incentive Plan (the “LTIP”). Awards under the LTIP are to be granted by the Committee in the form of RSUs and are to be treated as Performance Awards under the Equity Incentive Plan. Grants of RSUs under the LTIP shall initially be unvested and represent the maximum amount of shares that participants may receive under the LTIP, assuming achievement of the maximum level of performance goals established for the grant, and subject to adjustment for certain transactions and other non-recurring events that may affect Luminex or its financial performance. On December 4, 2008, our Chief Executive Officer was granted an unvested RSU under the LTIP for 102,564 shares of Luminex Common Stock, and our Chief Operating Officer was granted an unvested RSU under the LTIP for 76,923 shares of Luminex Common Stock. Partial or complete vesting of the RSUs shall be dependent upon the continued employment and the achievement of certain performance goals during the performance period extending from the date of grant through December 31, 2010. Our Chief Operating Officer forfeited his entire grant upon his resignation on February 1, 2009. Performance goals under the grants are based on the following components, with the following weights given to each: 50% on the trading price of Luminex Common Stock at the end of the performance period and 50% on Luminex’s operating cash flows per diluted share at the end of the performance period as described below:

• Partial or complete achievement of the trading price goal is dependent upon the average closing price of Luminex’s Common Stock for the twenty consecutive trading days ending December 31, 2010, inclusive, subject to certain adjustments as described in the LTIP. There is a range of trading price targets as follows: a minimum threshold of $24.79 per share, a target of $28.17 per share, and a maximum goal of $44.73 per share.

• Partial or complete achievement of the operating cash flow goal is dependent upon the average quarterly “total operating cash flows” per diluted share for the four quarters ended December 31, 2010, as further described in the LTIP. “Total operating cash flows” means Luminex’s GAAP net cash provided by operating activities as shown on its financial statements for the 12 month period ended December 31, 2010, as further described in the LTIP. There is a range of targets as follows: a minimum threshold of $0.101 per share, a target of $0.111 per share, and a maximum goal of $0.157 per share.

In the event that a participant achieves less than the maximum level of the performance goals, the total number of shares represented by such RSU shall be reduced to reflect where actual performance lies in the range of performance goals and weighted aggregate corresponding payout opportunities established for the grant. Calculation of shares between threshold and maximum performance shall be determined based on straight-line interpolation.

73

Accounting for Stock Compensation

Stock-based compensation costs are generally based on the fair value calculated from the Black-Scholes option-pricing model on the date of grant for stock options and market value on the date of grant for RSAs. The fair values of stock are amortized as compensation expense on a straight-line basis over the vesting period of the grants.

In accordance with SFAS 123(R), the Company evaluates the assumptions used in the Black-Scholes model at each grant date using a consistent methodology for computing expected volatility, expected term and risk-free rate of return. Calculation of expected volatility is based on historical volatility. The expected term is calculated using the contractual term of the options as well as an analysis of the Company’s historical exercises of stock options. The estimate of the risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant. The Company has never paid cash dividends and does not currently intend to pay cash dividends, and thus has assumed a 0% dividend yield. The assumptions used are summarized in the following table:

	2008			2007			2006

As part of the requirements of SFAS 123(R), the Company is required to estimate potential forfeitures of stock grants and adjust compensation cost recorded accordingly. The estimate of forfeitures is based on historical forfeiture performance and will be adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from such estimates. Changes in estimated forfeitures will be recognized through a cumulative catch-up adjustment in the period of evaluation and will also impact the amount of stock compensation expense to be recognized in future periods.

Employee Savings Plans

Effective January 1, 2001, the Company began sponsoring a retirement plan authorized by section 401(k) of the Internal Revenue Code. In accordance with the 401(k) plan, all employees are eligible to participate in the plan on the first day of the month following the commencement of full time employment. For 2008, 2007, and 2006, each employee could contribute a percentage of compensation up to a maximum of $15,500, $15,500, and $15,000 per year, respectively, with the Company matching 50% of each employee’s contributions. The Company’s contributions for 2008, 2007 and 2006 were $536,000, $543,000, and $435,000, respectively.

NOTE 15 — COMMITMENTS AND CONTINGENCIES

Lease Arrangements

The Company has operating leases related primarily to its office and manufacturing facilities with original lease periods up to 10 years. Rental and lease expense for these operating leases for the years 2008, 2007 and 2006 totaled approximately $2.6 million, $1.2 million, and $995,000, respectively.

Minimum annual lease commitments as of December 31, 2008 under non-cancelable leases for each of the next five years and in the aggregate were as follows (in thousands):

2009	$	1,966
2010		1,733
2011		1,735
2012		1,768
2013		1,782
Thereafter		1,947
Total	$	10,931

These non-cancelable lease commitments related to facilities include certain rent escalation provisions which have been included in the minimum annual rental commitments shown above. These amounts are recorded to expense on a straight-line basis over the life of the lease. In addition, some of the Company’s leases contain options to renew the lease for five to ten years at the then prevailing market rental rate, right of first refusal to lease additional space that becomes available, or leasehold improvement incentives

Non-Cancelable Purchase Commitments

As of December 31, 2008 the Company had approximately $10.1 million in purchase commitments with several of its inventory suppliers. These commitments require delivery of minimum amounts of components throughout 2017.

Employment Contracts

The Company has entered into employment contracts with certain of its key executives. Generally, certain amounts may become payable in the event the Company terminates the executives’ employment without cause or the executive resigns for good reason.

Gain on Settlement of Liability

In 2007, the Company renegotiated a contract acquired as part of the acquisition of Tm Bioscience. As part of the contract renegotiation there was a settlement of a liability of $2.3 million which we have recorded as a gain on settlement of liability in 2007.

Legal Proceedings

On January 16, 2008, Luminex and LMD were served with a complaint, filed by SUNY in Federal District Court for the Northern District of New York, alleging, among other claims, that LMD breached its license agreement with SUNY by failing to pay royalties allegedly owed under the agreement. The complaint seeks an undetermined amount of damages as well as injunctive relief. On February 9, 2008, Luminex and LMD filed an answer to this complaint denying all claims brought by SUNY. The Court issued a new scheduling order on January 16, 2009 to establish deadlines for completion of discovery. A trial date has not been set. The parties are engaging in the discovery process. As the litigation process is inherently uncertain, the Company is unable to estimate the possible loss related to this matter.

78

Unfunded Credit Facility

On March 1, 2007, the Company entered into a senior revolving credit facility with JPMorgan Chase Bank, N.A., which provided borrowings of up to a maximum aggregate principal amount outstanding of $15.0 million based on availability under a borrowing base consisting of eligible accounts and inventory. The obligations under the senior revolving credit facility were guaranteed by the wholly-owned domestic subsidiaries of the Company and secured by all of the accounts, equipment inventory and general intangibles (excluding intellectual property) of the Company and the guarantors including the pledge of an intercompany note from LMD and payable to the Company. Loans under the senior credit facility accrued interest on the basis of either a base rate or a LIBOR rate. The base rate was calculated daily and was the greater of (i) prime minus 1.00% and (ii) federal funds rate plus .50%. Borrowings at the LIBOR rate were based on one, two or three month periods and interest was calculated by taking the sum of (i) the product of LIBOR for such period and statutory reserves plus (ii) 1.75%. We paid a fee of 0.125% per annum on the unfunded portion of the lender’s aggregate commitment under the facility. Approximately $10.4 million was available for borrowing at December 31, 2008. The Company elected not to renew this credit facility on February 26, 2009.

The senior credit facility contained conditions to making loans, representations, warranties and covenants, including financial covenants customary for a transaction of this type. Financial covenants included (i) a tangible net worth covenant of $35.0 million following the acquisition and (ii) a liquidity requirement of availability not less than the funded debt of the Company and its subsidiaries (including LMD) calculated using the unencumbered cash, cash equivalents and marketable securities of the Company and the guarantors. The senior credit facility also contained customary events of default as well as restrictions on undertaking certain specified corporate actions, including, among others, asset dispositions, acquisitions and other investments, dividends, fundamental corporate changes such as mergers and consolidations, incurrence of additional indebtedness, creation of liens and negative pledges, transactions with affiliates and agreements as to certain subsidiary restrictions and the creation of additional subsidiaries. If an event of default occurred that was not otherwise waived or cured, the lender may have terminated its obligations to make loans under the senior credit facility and may have declared the loans then outstanding under the senior credit facility to be due and payable. We believe we were in compliance with our financial and other covenants under the senior credit facility. As of December 31, 2008, no amounts were outstanding under the senior revolving credit facility.

NOTE 16 — GUARANTEES

The terms and conditions of the Company’s development and supply and license agreements with its strategic partners generally provide for a limited indemnification of such partners, arising from the sale of Luminex systems and consumables, against losses, expenses and liabilities resulting from third-party claims based on an alleged infringement on an intellectual property right of such third party. The terms of such indemnification provisions generally limit the scope of and remedies for such indemnification obligations. To date, the Company has not had to reimburse any of its strategic partners for any losses arising from such indemnification obligations.

NOTE 17 — SEGMENT AND GEOGRAPHIC INFORMATION

The Chief Operating Decision Maker (CODM), as defined by SFAS No. 131, is Luminex’s Chief Executive Officer. The CODM allocates resources to and assesses the performance of each operating segment using information about its revenue and projections. Our reporting segments reflect the nature of the products offered to customers and the markets served and are comprised of the following:

Technology Segment —represents our base business and consists of system sales to partners, raw bead sales, royalties, service and support of the technology, and other miscellaneous items.

Assay Segment— consists of LBG and LMD and is primarily involved in the development and sale of assays on xMAP technology for use on Luminex’s installed base of systems.

79

Intersegment sales are recorded at fixed prices which approximate the prices charged to third party strategic partners and are not a measure of segment operating earnings.

Following is selected information for the years ended December 31, 2008 and 2007 or as of December 31, 2008 and 2007 (in thousands), with recognition that the LMD impact in 2007 is only for the period of March 1, 2007 through December 31, 2007:

NOTE 18 — SETTLEMENT OF LITIGATION

The Company settled its pending litigation with Rules Based Medicine, Inc. (“RBM”) on October 15, 2007. As part of the settlement, Luminex received a cash payment of $12.5 million in 2007. The cash payment was made by RBM in exchange for resolution of the dispute between the companies regarding Biophysical Corporation as well as the retirement of Luminex’s stock ownership in RBM and the grant of certain additional licensing rights from Luminex. All other terms of the agreement are confidential. The parties formally dismissed the lawsuit on October 24, 2007, as required by the settlement agreement. We recorded $11.5 million of the $12.5 million payment in the fourth quarter of 2007 as a gain on settlement of litigation. The remaining $1.0 million has been deferred related to the license agreement with RBM and will be recognized over the term of the license agreement.

NOTE 19 — RECENT ACCOUNTING PRONOUNCEMENTS

In September 2006, the FASB issued FAS No. 157, “Fair Value Measurements” (FAS 157). FAS 157 provides enhanced guidance for using fair value to measure assets and liabilities. It does not require any new fair value measurements, but does require expanded disclosures to provide information about the extent to which fair value is used to measure assets and liabilities, the methods and assumptions used to measure fair value, and the effect of fair value measures on earnings. FAS 157 is effective for financial assets and financial liabilities for fiscal years beginning after November 15, 2007. In February 2008, the FASB issued FASB Staff Position FAS 157-2, “Effective Date of FASB Statement No. 157” (the “FSP”). The FSP delayed, for one year, the effective date of FAS 157 for all nonfinancial assets and liabilities, except those that are recognized or disclosed in the financial statements on at least an annual basis. The implementation of FAS 157 for financial assets and financial liabilities, effective January 1, 2008, did not have a material impact on the Company’s consolidated financial position and results of operations. The Company is currently assessing the impact of FAS 157 for nonfinancial assets and nonfinancial liabilities on its consolidated financial position and results of operations.

In October 2008, the FASB issued FAS 157-3, “Determining the Fair Value of a Financial Asset When the Market for That Asset Is Not Active” (FAS 157-3). FAS 157-3 clarifies the application of FASB Statement No. 157,Fair Value Measurements, in a market that is not active and provides an example to illustrate key considerations in determining the fair value of a financial asset when the market for that financial asset is not active. The FSP is effective upon issuance, including for prior periods for which financial statements have not been issued. Revisions resulting from a change in the valuation technique or its application should be accounted for as a change in accounting estimate following the guidance in FASB Statement No. 154,Accounting Changes and Error Corrections. However, the disclosure provisions in Statement 154 for a change in accounting estimate are not required for revisions resulting from a change in valuation technique or its application. The Company believes the impact of this pronouncement on the Company’s consolidated financial statements to be immaterial.

In February 2007, the FASB issued FAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities — Including an amendment of FASB Statement No. 115” (FAS 159). FAS 159 permits entities to choose to measure many financial assets and financial liabilities at fair value. Unrealized gains and losses on items for which the fair value option has been elected are reported in earnings. FAS 159 is effective for fiscal years beginning after November 15, 2007. The implementation of this standard did not have a material impact on the Company’s consolidated financial position and results of operations.

In December 2007, the FASB issued FAS No. 141 (Revised 2007), “Business Combinations”(FAS 141R) which replaces FAS No. 141, “Business Combinations” and FAS No. 160, “Noncontrolling Interests in Consolidated Financial Statements” (FAS 160). FAS 141R establishes principles and requirements for how an acquirer recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, any noncontrolling interest in the acquiree and the goodwill acquired. FAS 141R also establishes disclosure requirements that will enable users to evaluate the nature and financial effects of the business combination. FAS 160 clarifies the classification of noncontrolling interests in the financial statements and the accounting for and reporting of transactions between the reporting entity and holders of such noncontrolling interests. FAS 141R and FAS 160 are effective for the Company’s fiscal year 2009 and must be applied prospectively to all new acquisitions closing on or after January 1, 2009. Upon adoption, these standards will not have a material impact on the Company’s consolidated financial position and result of operations. However, if the Company enters into any business combinations after the adoption of FAS 141R, a transaction may significantly impact its consolidated financial position and results of operations as compared to its recent acquisition, accounted for under existing GAAP requirements, due to the changes described above.

81

In April 2008, the FASB issued FASB Staff Position (FSP) FAS No. 142-3, “Determination of the Useful Life of Intangible Assets” (FSP FAS 142-3). FSP FAS 142-3 amends the factors that should be considered in developing renewal or extension assumptions used to determine the useful life of a recognized intangible asset under FASB Statement No. 142, “Goodwill and Other Intangible Assets”. FSP FAS 142-3 is effective for financial statements issued for fiscal years beginning after December 15, 2008, and interim periods within those fiscal years. Early adoption is prohibited. Based on its current operations, the Company does not expect that the adoption of FSP FAS 142-3 will have a material impact on its consolidated financial position or results of operations.

In May 2008, the FASB issued FAS No. 162, “The Hierarchy of Generally Accepted Accounting Principles” (FAS 162). FAS 162 identifies the sources of accounting principles and the framework for selecting the principles used in the preparation of financial statements of nongovernmental entities that are presented in conformity with generally accepted accounting principles in the United States (the GAAP hierarchy). FAS 162 will become effective 60 days following the SEC’s approval of the Public Company Accounting Oversight Board amendments to AU Section 411,The Meaning of Present Fairly in Conformity With Generally Accepted Accounting Principles. The Company does not expect this standard will have a material impact on its financial position or results of operations.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures, as defined in Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934 (Exchange Act), which are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act 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 timely decisions regarding required disclosure. 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 procedure as of the end of the period covered by this report. Based on the evaluation and criteria of these disclosure controls and procedures, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2008 based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on that evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 2008. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The Company’s independent registered public accounting firm, Ernst & Young LLP, has issued a report on their assessment of the effectiveness of the Company’s internal control over financial reporting, which is provided at Item 8, page 51.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting identified in connection with the evaluation required by Exchange Act Rule 13a-15(d) during the fourth quarter of 2008 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
