Overview

We are the world leader in hand-carried ultrasound, or HCU, systems. We specialize in the development of HCU systems for use in a variety of medical
specialties in a range of clinical settings at the point-of-care. Our proprietary technologies have enabled us to design HCU systems that combine high resolution, all-digital, broadband imaging with advanced features and capabilities typically found
on cart-based ultrasound systems. We believe that the performance, size, durability, ease of use and cost-effectiveness of our products are expanding existing ultrasound markets, and are opening new markets by bringing ultrasound visualization out
of the imaging lab to the point-of-care such as the patients bedside or the physicians examining table for diagnosis and procedural guidance.

The large size, weight and complexity of traditional cart-based ultrasound systems typically require a physician or highly trained clinician to perform the examination in a centralized imaging department, such as a
hospitals radiology department. Our strategic intent is to enable clinicians to use ultrasound in a variety of clinical settings by developing each potential market based on three fundamental tenets: (i) the design of high performance
system hardware, software and transducers with application-specific settings and capabilities; (ii) the provision of educational training that ensures appropriate use of the equipment in the clinical setting; and

##### Table of Contents

(iii) the support of professional institutions and ultrasound thought leaders in the completion of use protocols and clinical research that accelerates
the adoption of HCU to improve patient outcomes. By providing ultrasound at the primary point-of-care, our systems expedite diagnosis and treatment in acute and critical care settings and provide visual guidance for interventional procedures. In
outpatient settings, our systems can eliminate delays associated with the outpatient referral process. This increased accessibility is changing clinical practice, improving patient care and safety and has the potential to reduce healthcare costs
through earlier diagnosis of diseases and conditions.

We design our products for applications where ultrasound has not typically been used
such as emergency medicine, surgery, critical care, internal medicine and vascular access procedures as well as for imaging in traditional applications, such as radiology, cardiology, vascular medicine and obstetrics and gynecology
(OB/Gyn). In addition, the U.S. military has successfully deployed our systems in traditional hospital settings, field hospitals and forward surgical teams in war zones and areas of conflict. We began shipping our first products in
September 1999 and today have an installed base of thousands of systems worldwide.

Our fourth generation product platform is the basis of
two product lines, the M-Turbo (TM) system and the S Series (TM) ultrasound tools, which we introduced in October 2007. These products together with the MicroMaxx (R) system, our third generation of hand-carried technology and introduced in
2005, offer a broad-based product portfolio for hospital and physician office markets. Based on our proprietary Application Specific Integrated Circuit (ASIC) technology for high-resolution ultrasound imaging these systems offer image
resolution comparable to costly, conventional cart-based ultrasound systems weighing over 200 pounds. A five-year warranty covering the system and most of the transducers, comes standard with these products.

Our second generation product, the TITAN (R) system, began shipping in 2003. This system addresses point-of-care and traditional ultrasound markets.
Our first generation of products includes the 180 (TM) and iLook (R) series. The SonoSite 180PLUS (TM) system is designed for general ultrasound imaging and the SonoHeart (R) ELITE is specifically configured for cardiovascular
applications. The iLook 25 imaging tool is designed to provide visual guidance for physicians and nurses while performing vascular access procedures and the iLook 15 imaging tool is designed to provide imaging of the chest and abdomen.

We commenced operations as a division of ATL Ultrasound, Inc., or ATL. On April 6, 1998, we became an independent, publicly owned company through
a distribution of one new share of our stock for every three shares of ATL stock held as of that date. ATL retained no ownership in SonoSite following the spin-off.

Medical Ultrasound Imaging

Ultrasound uses low power, high frequency sound waves to provide
noninvasive, real-time images of the bodys soft tissue, organs and blood flow. Ultrasound can be cost effective by eliminating the need for more time intensive, invasive and expensive procedures and allowing for earlier diagnosis of diseases
and conditions. Further, it does not expose the patient to ionizing radiation that is present in X-ray and computed tomography technology. To generate an ultrasound image, a clinician places the transducer on the skin or in a body cavity near or by
the targeted area of interest. Tissues and bodily fluids reflect the sound waves emitted by the transducer, which then receives these reflections. Based on these reflections, the ultrasound systems beamformer measures and organizes the sound
waves and produces an image for visual examination, using digital or analog signal processing, or a combination of the two. Broadband digital signal processing technology, such as that used by our products, allows an ultrasound system to obtain and
process greater amounts of information. Accordingly, digital ultrasound systems produce higher resolution images than analog and hybrid analog/digital ultrasound machines.

Standard ultrasound imaging produces a two-dimensional image, known as grayscale or 2D imaging, which physicians use to diagnose, stage and monitor
disease states and conditions. Color Doppler technology expands standard ultrasound imaging by generating a colorized image showing the presence and direction of blood flow.

Through the use of software algorithms in the ultrasound system, clinicians can provide a quantitative assessment of anatomical structures and physiological
functions such as blood flow velocity and cardiac ejection fraction.

Our Markets

According to estimates by Klein Biomedical Consultants, Inc. (Klein), the worldwide ultrasound market in 2006 was $3.9 billion (excluding
upgrades and service). Radiology or general imaging is the largest clinical segment and accounts for 36% of this market. Cardiology and OB/Gyn account for 25% and 23%, respectively. Vascular medicine and other applications account for the remaining
16%. The U.S. market represents 31% of the worldwide market. An important clinical segment within the international market is the shared services market, which is comprised of systems configured to perform both radiology and cardiology examinations.
Based on industry analyst reports, we estimate that this market accounts for 20% of the international market, or $540 million.

In 2003,
industry analysts began to separately track the market for HCU, which are products defined as laptop-sized systems weighing 12 pounds or less. Worldwide sales of HCU products have grown from $10 million in 1999, when SonoSite began shipping the
first HCU products, to estimated sales of $397 million in 2006 with sales approximately evenly divided between U.S. and international markets, according to Klein. Some of the market growth in HCU has and will come at the expense of cart-based
systems. Our market focus, and we believe the greatest growth opportunities, will come from new point-of-care clinical applications and new users of ultrasound due to clinical needs that are best addressed by the high performance, mobility,
durability, ease-of-use and other attributes of our HCU products.

Our markets can be classified by location and clinical application. From
a location perspective, we see our growth continuing to come from further penetration into the hospital market, the major source of our revenue today. Additionally, we see strong future growth opportunities from sales into the clinic or private
office, as well as into alternate care sites. On a clinical application basis, within the hospital, we see accelerating growth in non- traditional or point-of-care ultrasound markets such as acute and critical care. In the clinic or
private practice office setting, we believe that slower growth in the more competitive markets, such as radiology, cardiology and OB/Gyn, will be balanced by accelerating growth trends and interest in outpatient physician office settings. We
consider the use of HCU in the military and disaster settings as promising opportunities, as well as expanded use in mobile screening services and other non-clinical sites.

Our Strategy

Our goal is to lead in the design, development and commercialization of
high-performance, innovative ultrasound technology and HCU systems. We plan to increase our share in markets that we currently serve and also seek growth by entering new markets with significant opportunities. Our strategy to achieve our objectives
consists of the following key elements:



| |  |  | Continue to lead the HCU market by building upon and expanding product and technology leadership. We believe our products represent the most advanced and
innovative technology available in HCU systems. We are committed to continuing to expand this technological advantage by further enhancing our existing products and creating new ones. As of December 31, 2007, we employed approximately 110
people in research and development. Since our inception in 1998, we have introduced four generations of our hand-carried ASIC technology, which have improved performance and expanded clinical capabilities of our systems. The M-Turbo system and S
Series ultrasound tools based on our fourth generation ASIC technology, provide scalable technology platforms that will enable us to deliver products to specific clinical applications that vary by size, cost and performance.

| |  |  | Maximize the productivity of our direct sales force. As of December 31, 2007, we employed over 100 direct sales representatives in the U.S., the United
Kingdom, France, Germany, Spain, Italy, Japan, Australia and Canada. In January 2008, we mutually terminated our relationship with MarketBridge,
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | which had provided a contract sales force for the physician office market since mid 2006. As part of this termination we hired 18 direct sales
representatives, who were formerly with MarketBridge, to address the U.S. physician office market. To further enhance the productivity of our direct sales force, we will continue to:
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | invest in training and educating our sales force;
| | - |  | -------------------------------------------------



| |  |  | maximize sales to our installed base;
| | - |  | -------------------------------------



| |  |  | provide education to increase market awareness and generate new customer leads; and
| | - |  | -----------------------------------------------------------------------------------



| |  |  | expand our corporate account relationships.
| | - |  | -------------------------------------------



| |  |  | Broaden our sales distribution channels; enter into strategic relationships. We believe that other markets offer opportunity for growth, but will require
enhancements to our sales distribution channels. For example, we have strategic alliances with NAMIC/VA Inc., which purchased the vascular access business of Boston Scientific Corporation with whom we had a previous relationship, and Nippon Sherwood
Medical Industries Ltd. for distribution of our iLook product in the U.S. and Japan, respectively. We intend to enter into new third party distributor arrangements and explore strategic relationships to develop markets within ultrasound or with
ultrasound-dependent technologies. We believe that strategic relationships can accelerate market penetration to customers not served by our direct sales force.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Drive our technology across the clinical spectrum. We believe that the performance, mobility, durability and cost
effectiveness of our products are resulting in the creation of new clinical markets for us. We are expanding the use of ultrasound beyond the imaging center to the patient point-of-care, such as the emergency room, the physicians office and
other non-traditional ultrasound settings. With the addition of our SonoCalc® IMT software, which allows physicians to measure the wall thickness (known as the IMT) of the
carotid artery, we have taken initial steps to enter the market for cardiovascular disease management. We believe that new markets like these will offer us significant potential for additional growth.

and cardiac cath labsare the first ultrasound devices to offer the option of a zero footprint and can be mounted on a pole, fixed on a wall or ceiling or hand-carried to the point-of-care. Transducers are interchangeable between the M-Turbo
and S Series product lines. A 5-year warranty comes standard on the system and most of the transducers.

MicroMaxx
System. The MicroMaxx system, first shipped in June 2005, weighs 7.7 pounds (with battery) and is a high performance, hand-carried ultrasound system. It has 13 transducers and can be configured for use in anesthesia, cardiology, critical and
acute care, emergency medicine, OB/Gyn, preventive cardiology, radiology, surgery and vascular applications. A 5-year warranty comes standard on the system and most of the transducers. The MicroMaxx system may be upgraded with purchased software
features that can be added through a standard flashcard.

SonoSite TITAN. The TITAN system, first shipped in June
2003, weighs 7.5 pounds. Like the MicroMaxx system, the TITAN system features a larger display screen than the 180 or iLook products and has removable memory flashcards for enhanced image or study storage. The TITAN system may be upgraded with
purchased software features that can be added through a standard flashcard.

SonoSite 180 Series. The 180 Series
consist of the 180PLUS and SonoHeart Elite, each weighing approximately 5.4 pounds. The SonoSite 180PLUS system is a point-of-care ultrasound system for general diagnostic and procedural assistance imaging. It was our initial product that created
the hand-carried ultrasound category. The SonoHeart ELITE system is a point-of-care ultrasound system with expanded measurement tools and clinical analysis packages intended for use by cardiologists and other healthcare providers in the cardiology
or bedside assessment market. The SonoHeart ELITE has all the product features of the SonoSite 180PLUS.

iLook
Series. The iLook series consists of the iLook 15 and 25, each weighing approximately 3 pounds. The iLook 15 tool, with its fixed curved array transducer, provides imaging for focused abdominal and cardiac applications. The iLook 25 tool, with
its fixed linear transducer, enables the clinician to visualize a patients vessels to aid in vascular access applications.

We also
offer accessories and clinical education programs including:



| |  |  | Accessories. We offer a wide selection of accessories for our products. These include mobile docking stations, multiple transducer connections, image
transfer and management software, printers, video recorders, auxiliary monitors, storage devices, carrying cases and disposable supplies.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Specialized training and education. We develop education programs independently and in partnership with numerous medical societies and other recognized
experts in ultrasound education to provide courses for our customers through the SonoSite Institute for Training and Education. We have pioneered a unique online education site, which has been developed for the benefit of existing customers in the
traditional and emerging markets that are new to the routine use of ultrasound.

| | Additionally, with the introduction of the M-Turbo and S Series we developed the Education Key programa USB thumb drive that contains a
combination of system operation video tutorials, application-specific video refresher programs that provide peer-to-peer instruction on how to perform specific exams and procedures and an image reference library of application specific sonographic
anatomy for comparison purposes. As we develop new and emerging markets, we plan to continue to support the development of accredited and market-specific training materials, and expand the use of workshops in conjunction with recognized leaders in
ultrasound.

Sales and Marketing

We currently sell our products through sales channels comprised of direct sales representatives, clinical application specialists and their managers, independent third-party distributors managed by distribution
managers, and strategic alliances. As of December 31, 2007, we employed over 100 direct sales representatives in the U.S. and in our wholly-owned subsidiaries located in the United Kingdom, Germany, France, Spain, Italy, Japan, Australia and
Canada. In addition to our direct sales, we sell products in over 100 countries through a network of independent third-party distributors. In addition, we employ regional distribution managers responsible for Middle East and Africa, Europe, Latin
America, China, India and Asia.

In the U.S., we have complemented our direct sales efforts by entering into group purchasing agreements
with major healthcare group purchasing organizations (GPO). Currently, we have GPO supply agreements with various groups including Amerinet, Inc., Premier, Inc., Novation LLC, MedAssets HSCA, Inc., Consorta, Inc., and Broadlane, Inc.
(includes Kaiser Permanente, Tenet Healthcare and others). We also have two supply agreements with the U.S. government, specifically with the Defense Supply Center of Philadelphia and the General Services Administration. In the United Kingdom, we
have a supply agreement with the Purchasing and Supply Agency of the National Health Service, which contracts on a national basis for the purchase of products and services.

We derived 51% of our revenue from domestic sales in 2007 compared to 52% in 2006 and 54% in 2005. We attribute revenue to a foreign country based on the
location to which we ship our products. Products sold to the U.S. government but deployed in a foreign country are attributed to domestic revenue. Our quarterly revenue is affected by seasonality from year to year with the fourth quarter having the
highest revenue, and first quarter being typically the lowest. Quarterly revenue patterns may be affected somewhat by large government orders or shipment of product inventory to new distributors. We currently have one reporting segment. For
information regarding revenues and long-lived assets by geography, refer to Note 15 of our consolidated financial statements.

Patents and Intellectual
Property Rights

We rely on a combination of patent, copyright, trademark and trade secret laws and other agreements with employees and
third parties to establish and protect our proprietary rights. We require our officers, employees and consultants to enter into standard agreements containing provisions requiring confidentiality of proprietary information and assignment to us of
all inventions made during the course of their employment or consulting relationship. We also enter into nondisclosure agreements with our commercial counterparties and limit access to, and distribution of, our proprietary information.

We are committed to developing and protecting our intellectual property and, where appropriate, filing patent applications to protect our technology.
We hold 26 U.S. patents relating to various aspects of our products, including digital beamformers, beamforming capabilities, digital conversion circuitry, transceiver circuitry, designs and circuit integration. We hold 29 foreign patents relating
to our products, and we currently have 39 patent applications pending in the U.S. and 43 pending registrations abroad.

We license
ultrasound technology from ATL under a Technology Transfer and License Agreement executed at the time of our spin-off as a public company in 1998. Under that agreement, we took ownership of certain



8

##### Table of Contents

ultrasound technology developed as part of a government grant and also patent rights, which had been established or were being pursued for that technology.
As part of this agreement, we also entered into a cross-license whereby we had the exclusive right to use certain ATL technology existing on April 6, 1998 or developed by ATL during the three-year period following April 6, 1998 in
ultrasound systems weighing 15 pounds or less, and ATL had the exclusive right to use our technology existing on April 6, 1998 or developed by us during the same three-year period in ultrasound systems weighing more than 15 pounds. On
April 6, 2003, this cross-license became nonexclusive and, except for the patented technology of each party, now extends to all ultrasound systems regardless of weight.

We hold a number of registered and unregistered trademarks, service names and domain names that are used in our business in the U.S. and overseas.
Generally, federally registered trademarks offer protection for renewable terms of 10 years so long as the mark continues to be used in commerce.

In order to protect or enforce our patent rights, we may initiate patent litigation. For example, we filed a patent infringement suit against Zonare Medical Systems, Inc. (Zonare) in the federal district court in the Central
District of California alleging that Zonare infringed one of our key patents through sales of its z.one ultrasound system. On March 14, 2007, Zonare filed an answer to our claim which included a counterclaim against us alleging that our
products infringe its patent related to its portable docking station.

Others may initiate patent litigation against us. On May 15,
2007, GE Healthcare, (GE) a competitor of ours, filed a lawsuit against us in the federal district court in the Western District of Wisconsin. The lawsuit alleges that our MicroMaxx and/or TITAN products willfully infringe certain of
GEs U.S. patents relating to ultrasound technology. GE is seeking unspecified monetary damages and an injunction. On July 5, 2007, we filed a counterclaim against GE and certain of its affiliates. In parallel, we filed our answer to the
complaint denying all of GEs claims and alleging that the asserted patents are either invalid, not infringed, or both. Subsequent to these initial filings, both parties supplemented their claims with additional allegations of patent
infringement. Our complaint also seeks unspecified monetary damages and a court injunction against future infringement by GE and its affiliates.

Competition

We currently face competition from companies that manufacture cart-based and portable ultrasound systems. Many
of our competitors are larger and have greater resources than we do and offer a range of products broader than our products. The dominant competitors in this industry are GE Healthcare, a unit of General Electric Company (GE Healthcare),
Siemens Medical Solutions (Siemens) and Philips Medical Systems, a division of Koninklijke Philips Electronics, N.V. (Philips). In addition, as the market for high-performance, HCU systems develops, we expect competition to
increase as potential and existing competitors enter the portable market or modify their existing products to more closely approximate the combined portability, quality, performance and cost of our products. Our current competitors in the portable
market include Siemens, GE Healthcare, Philips, Biosound Esaote, Inc., Medison America Inc., a subsidiary of Medison Company, Ltd. (Medison America), Terason, a division of TeraTech Corporation (Terason), and Zonare Medical
Systems, Inc., a privately held company (Zonare).

Research and Development and Technology

We currently employ approximately 110 people in research and development. In 2007, 2006 and 2005, expenses attributable to research and development for
our business totaled $25.9 million, $20.2 million and $15.2 million. We believe our products represent the most advanced and innovative technology in high-performance, HCU systems. We believe our technology gives us a competitive advantage, and we
are committed to maintaining this advantage by continuing to enhance our existing products and create new ones.

Manufacturing

Final assembly and testing of all products is done in our facility in Bothell, Washington. We depend on suppliers, including some single-source suppliers, to provide highly specialized parts and subassemblies, such as custom-designed
integrated circuits, circuit boards, cable assemblies and transducer components. We also depend on single-source suppliers to provide other components, such as image displays, batteries, capacitors and cables. We maintain inventories of components
to meet near-term production requirements. While our suppliers have generally produced our components with acceptable quality, quantity and cost in the past, they have experienced periodic problems that have caused us delays in production. To date,
these problems have not resulted in lost sales or lower demand.

Governmental Regulation

The manufacture and sale of our products are subject to extensive regulation by numerous governmental authorities, principally the U.S. Food and Drug
Administration, (FDA), as well as several other state and foreign agencies. The FDA requires that we obtain a pre-market notification clearance under Section 510(k) of the Federal Food, Drug & Cosmetic Act prior to
introducing our products to the market. By granting 510(k) clearance, the FDA indicates agreement with an applicants determination that the product for which clearance has been sought is substantially equivalent to medical devices that were on
the market prior to 1976 or have subsequently received clearance. The process of obtaining 510(k) clearance typically takes approximately two to three months, but it can take significantly longer. To date, all of our products have received 510(k)
clearance.

Many of the regulations applicable to our products in foreign countries are similar to those of the FDA. Some foreign
regulatory agencies require similar pre-market clearance or registration before our products can be marketed or offered for sale in their countries. Such foreign regulatory approvals may be longer or shorter than that required for FDA clearance and
the requirements may differ significantly. The national health or social security organizations of certain countries may additionally require our products to be qualified before they can be marketed in those countries. We cannot be assured that such
clearances will be obtained.

We are subject to regulations in each of the foreign countries in which we sell products. Currently, our
products bear a CE Mark, which indicates that our products comply with the requirements of the applicable European Union Medical Device Directive. Medical devices properly bearing the CE marking may be commercially distributed throughout the
European Union. We have received certification from the British Standards Institute (BSI) for conformity with certain quality system standards allowing us to place the CE mark on our product lines. The quality system has been developed
by the International Organization for Standardization to ensure that companies are aware of the standards of quality to which their products will be held worldwide. While no additional pre-market approvals in individual European Union countries are
required prior to marketing a device bearing the CE marking, practical complications with respect to marketing introduction may occur. For example, differences among countries have arisen with regard to labeling requirements. We may not be
successful in maintaining certification requirements necessary for distribution of our products in the European Union and failure to maintain the CE marking will preclude us from selling our products there.

To ensure that manufacturers adhere to good manufacturing practices, medical device manufacturers are routinely subject to periodic inspections by the
FDA and may be inspected by foreign regulatory agencies from countries in which we do business. In addition, the BSI performs periodic assessments of our manufacturing processes.

Reimbursement

In the U.S., the Center for Medicare and Medicaid Services (CMS), establishes guidelines for the reimbursement of healthcare providers treating Medicare and Medicaid patients. Under current CMS guidelines, varying reimbursement
levels have been established for ultrasound imaging and diagnostic procedures performed by hospitals and physicians using our products. The actual reimbursement amounts are determined by individual state Medicare carriers and by private insurance
carriers for non-Medicare and Medicaid patients. Moreover, states as well as private insurance carriers may choose not to follow the CMS reimbursement guidelines. The use of our products outside the U.S. is similarly affected by reimbursement
policies adopted by foreign regulatory agencies and insurance carriers.

Service and Warranty

Our warranty period is five years for the MicroMaxx system, M-Turbo system and S Series ultrasound tools with certain exceptions. Our warranty period for
our other products is one year. The warranty is included with the original purchase. In addition to our standard warranty, we offer extended warranty agreements for maintenance beyond the standard warranty period or for coverage above what is
provided under the standard warranty. We repair equipment that is out of warranty on a time and materials basis. The warranty liability is summarized as follows (in thousands):



|                             |  |                            |       |                          |   |                     |  |   |                      |   |  |   |

Employees

As of December 31, 2007, we had approximately 600 employees, of which approximately 18% were engaged in product research and development, 22% in manufacturing, 45% in sales and marketing activities and the
remaining 15% in administrative capacities, including executive, finance, legal, human resources, regulatory and information services and technology. Of these, approximately 450 are U.S. employees. There has never been a work stoppage and no
employees are covered by collective bargaining agreements. We believe our employee relations are good.

|ITEM 1A. | RISK FACTORS.
|-------- | -------------

If we are unable to effectively develop new and
innovative products and product features that achieve market acceptance, our products will become technologically obsolete in the ultrasound market and our business will fail.

Because substantially all of our revenue comes from the sales of our existing HCU systems and related products, in order to remain competitive, our future
financial success will depend in large part upon our ability to successfully invent, deliver and market new and innovative products and product features. In October 2007, we released several new products, including the M-Turbo system and the S
Series ultrasound tools which are customized for different clinical applications. The development of new, technologically advanced products and product features is a complex and uncertain process requiring great innovation and the ability to
anticipate technological and market trends and needs. We may be unable to achieve or maintain market acceptance of any new products we develop, and we may be required to expend more costs than anticipated to successfully introduce these products.
Without successful product innovation and market introduction of new offerings and improvements, our products will become technologically obsolete and we will be unable to compete effectively in the ultrasound market. Even with successful innovation
and development, we cannot assure you that revenues from the sales of our HCU systems will continue to remain at or above current levels or that we will continue to be financially profitable.

Because technology innovation is complex, it can require long development and testing periods. If the launch of new products or product improvements is
delayed for any reason, our business may be adversely affected. Factors which could cause delays in our product development or release schedules or cancellation of our product development projects include:



| |  |  | research and development challenges;
| | - |  | ------------------------------------



| |  |  | defects or errors in newly developed products or software for those products;
| | - |  | -----------------------------------------------------------------------------



| |  |  | third-party intellectual property rights that preclude us from pursuing a new product design; and
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | the availability, cost and performance of supplies and components needed for new products.
| | - |  | ------------------------------------------------------------------------------------------

We may experience delays in our innovation cycle, and in the scheduled introduction of future new products. Any such delays could adversely affect our
ability to compete effectively in the ultrasound market and could adversely affect our operating results.

We may be unable to expand the market for our
products to new applications and new users, which will limit our ability to grow our business.

We seek to sell our products to current
users of ultrasound, as well as to physicians and other healthcare providers who do not currently use ultrasound. Our market focus, and we believe our greatest growth opportunities, will come from new point-of-care clinical applications and new
users of ultrasound. Any new users of ultrasound will not only require training and education to properly administer ultrasound examinations but also must develop an appreciation of the treatment value of our products so that our products will
become successfully integrated into their day-to-day practices. Although we have spent, and will continue to spend, considerable marketing resources educating potential customers about the value of HCU products in new applications, our efforts may
be unsuccessful. If these potential customers are unable or unwilling to be trained due to cost, time constraints, unavailability of courses or other reasons, or if they consider our products nonessential to their medical practices, our ability to
expand the market for our products and to increase our revenues could be limited.

##### Table of Contents

Our efforts to integrate the business and technology of any future acquisition may result in significant costs or
create significant disruptions that outweigh the benefits of any such acquisition.

We intend to explore the possible acquisition of one
or more medical device companies or medical device products in an effort to expand our product portfolio, expand our sales channels, create international operating leverage, improve marketing and other efficiencies and leverage manufacturing and
supply chain economics. In furtherance of this strategy, in July 2007, we raised $208.5 million in net proceeds from our senior convertible note transaction, net of issuance costs, a convertible note hedge transaction and a warrant transaction and
we may raise additional funds to position ourselves to pursue any desirable acquisition candidates that we may identify. If we are unable to identify suitable acquisition candidates or to successfully consummate and integrate acquisitions into our
business, our ability to grow our business may be limited. Also in July 2007, we acquired LumenVu, Inc. a private development stage company that has developed, in conjunction with a leading academic research institution, a patented technology to
improve the accuracy of catheter placement. We expect to introduce products based on this technology in early 2009.

Any acquisition we do
complete may be costly and difficult and we may experience:



| |  |  | difficulty in integrating operations, including combining teams and processes in various functional areas;
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | delays in realizing the benefits of the acquired company or technology;
| | - |  | -----------------------------------------------------------------------



| |  |  | limited market acceptance of acquired products or technology;
| | - |  | -------------------------------------------------------------



| |  |  | diversion of our managements time and attention from other business concerns;
| | - |  | ------------------------------------------------------------------------------



| |  |  | lack of or limited direct experience in new markets we may enter;
| | - |  | -----------------------------------------------------------------



| |  |  | difficulties in obtaining regulatory approvals or reimbursement codes for acquired technologies;
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | increased risk of product liability actions from acquired products or technologies;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | additional costs, including fees and expenses of professionals involved in completing the integration process; and
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | unexpected costs associated with existing liabilities of any acquired business.
| | - |  | -------------------------------------------------------------------------------

In addition, an acquisition could materially impair our operating results by causing us to incur additional debt or requiring us to incur one-time
charges or amortize acquisition expenses and related assets. If we fail in our attempts to integrate any acquired business or technology, or if the costs and burdens of such acquisition or integration outweigh the benefits of such acquisition, our
financial resources or financial results could be impaired.

If we are unable to compete effectively, we will fail to generate sufficient revenue to
maintain our business.

Competition in the cart-based and portable ultrasound systems market is very significant. Our main competitors
in this industry are GE Healthcare, Siemens, and Philips. These companies are very large global organizations that have the following competitive advantages over us:



| |  |  | significantly greater financial and infrastructure resources;
| | - |  | -------------------------------------------------------------



| |  |  | larger research and development staffs;
| | - |  | ---------------------------------------



| |  |  | greater experience in product manufacturing, marketing and distribution;
| | - |  | ------------------------------------------------------------------------



| |  |  | greater brand name recognition; and
| | - |  | -----------------------------------



| |  |  | long-standing relationships with many of our existing and potential customers.
| | - |  | ------------------------------------------------------------------------------



13

##### Table of Contents

These manufacturers of cart-based and portable ultrasound systems could use their greater resources to
further increase the level of competition in the market through various means, including:



| |  |  | price and payment terms that we are unable to match;
| | - |  | ----------------------------------------------------



| |  |  | marketing strategies that bundle the sale of portable systems with other medical products that we do not sell;
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | technological innovation;
| | - |  | -------------------------



| |  |  | market penetration and hospital systems integration that we cannot match;
| | - |  | -------------------------------------------------------------------------



| |  |  | employee compensation that we cannot match; and
| | - |  | -----------------------------------------------



| |  |  | complementary services such as warranty protection, maintenance and product training that are outside of the scope of our product offerings.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------

Existing product supply relationships between these competitors and our potential customers could adversely impact the
level or rate of adoption of our products due to brand loyalty or preferred customer discounts. Competing portable or traditional cart-based ultrasound devices may be more accepted or cost-effective than our products. Competition from these
companies for employees with experience in the primary point-of-care market could result in higher turnover of our employees. If we are unable to respond to competitive pressures within the cart-based and HCU markets, we could experience delayed or
reduced market acceptance of our products, higher expenses and lower revenue.

We expect the market for high-performance HCU products, and
the competition in the HCU market, to continue to increase as new and existing competitors enter the portable ultrasound market or modify their existing products to more closely approximate the combined portability, quality, performance and cost of
our products. If we are unable to compete effectively with current or new entrants to the high-performance HCU market, we will be unable to generate sufficient revenue to maintain our business.

If our relationships with our distributors are unsuccessful, our ability to sell our products will be limited.

We currently depend on distributors to help promote market acceptance and demand for our products in countries in which we do not have a direct sales
force. Distributors that are in the business of selling other medical products may not devote a sufficient level of resources and support required to generate awareness of our products and grow or maintain product sales. If our distributors are
unwilling or unable to market and sell our products, or if they do not perform to our expectations, we could experience delayed or reduced market acceptance and sales of our products.

In addition, disagreements with our distributors or non-performance by these third parties could lead to costly and time-consuming litigation or
arbitration and disrupt distribution channels for a period of time and require us to re-establish a distribution channel.

Existing or potential
intellectual property claims and litigation either initiated by or against us may divert our resources and subject us to significant liability for damages, substantial litigation expense and the loss of our proprietary rights.

In order to protect or enforce our patent rights, we may initiate patent litigation. For example, we filed a patent infringement suit against Zonare
Medical Systems, Inc. in the federal district court in the Central District of California alleging that Zonare infringed one of our key patents through sales of its z.one ultrasound system. On March 14, 2007, Zonare filed an answer to our claim
which included a counterclaim against us alleging that our products infringe its patent related to its portable docking station.

##### Table of Contents

Others may initiate patent litigation against us. On May 15, 2007, GE Healthcare, a competitor of
ours, filed a lawsuit against us in the federal district court in the Western District of Wisconsin. The lawsuit alleges that our MicroMaxx and/or TITAN products willfully infringe GEs U.S. patents Nos. 4,932,415, 5,584,294, 6,120,447,
6,210,327 and 6,418,225 relating to ultrasound technology. GE is seeking unspecified monetary damages and an injunction. On July 5, 2007, we filed a counterclaim against GE and certain of its affiliates. In parallel, we filed our answer to the
complaint denying all of GEs claims and alleging that the asserted patents are either invalid, not infringed, or both. In our counterclaim complaint, we assert that GE and its affiliated companies have infringed certain of our U.S. patents
through their sales of ultrasound products, including GEs compact ultrasound systems. Subsequent to these initial filings, GE added another patent to its claims in (U.S patent No. 6,102,859) and we added patents to our counterclaims
against GE so that we are now alleging infringement of four patents by GEs products (U.S. patent No. 6,569,101, 6,962,566, 6,364,839 and 6,471,651). Our complaint also seeks unspecified monetary damages and a court injunction against
future infringement by GE and its affiliates.

If we fail to successfully defend GEs claims or Zonares counterclaim, we may be
required to pay monetary damages (including treble damages) and, unless we are able to redesign our products to avoid infringing the asserted patents or to license proprietary rights from them, we may be prevented from continuing to market and sell
certain of our products, sales of which represent a substantial portion of our total revenue. If this outcome were to occur, we may be unable to redesign our products in a timely and cost effective manner, and licensing proprietary rights from GE or
Zonare may not be possible on commercially reasonable terms, if at all. Even if we are successful in defending these actions and in proving infringement by GE or Zonare, we will incur substantial costs that could adversely affect our financial
condition and the actions will be distracting to management.

We may become subject to interference proceedings conducted in patent and
trademark offices to determine the priority of inventions. There are numerous issued and pending patents in the ultrasound field. The validity and breadth of medical technology patents may involve complex legal and factual questions for which
important legal principles may remain unresolved.

We may be liable for infringing the intellectual property of others as there could be
existing patents of which we are unaware, or pending applications of which we are unaware which may later result in issued patents, that one or more of our products may infringe. Litigation may be necessary to:



| |  |  | assert or defend against claims of infringement;
| | - |  | ------------------------------------------------



| |  |  | enforce our issued and licensed patents;
| | - |  | ----------------------------------------



| |  |  | protect our trade secrets or know-how; or
| | - |  | -----------------------------------------



| |  |  | determine the enforceability, scope and validity of the proprietary rights of others.
| | - |  | -------------------------------------------------------------------------------------

We may also become involved in the defense and prosecution, if necessary, of intellectual property suits, patent interferences, opposition proceedings
and other administrative proceedings. For example, we successfully defended a patent infringement suit, Neutrino Development Corporation vs. SonoSite, in the U.S. District Court for the Southern District of Texas for more than five years, from 2001
through the end of 2006. Although we were successful, this litigation forced us to incur substantial costs.

Involvement in intellectual
property claims and litigation, including those described above, could have significant adverse consequences, including:



| |  |  | diversion of management, scientific and financial resources;
| | - |  | ------------------------------------------------------------



| |  |  | exposure to significant adverse judgments and financial liabilities;
| | - |  | --------------------------------------------------------------------



| |  |  | forcing us to incur substantial litigation costs;
| | - |  | -------------------------------------------------



| |  |  | causing product shipment delays and lost sales;
| | - |  | -----------------------------------------------

| |  |  | requiring us to enter into royalty or licensing agreements with third parties on terms that may not be acceptable to us; or

If we are unable to protect our patents and proprietary rights, we may be unable to compete effectively and we may lose sources of revenue.

Much of our value arises out of our proprietary technology and intellectual property for the design, manufacture and use of point-of-care ultrasound
imaging systems. We rely on patent, copyright, trade secret and trademark laws to protect our proprietary technology and limit the ability of others to compete with us using the same or similar technology. Third parties may infringe or
misappropriate our intellectual property, which could harm our business.

We currently hold 55 U.S and foreign patents relating to our
technology. A number of other patents are pending in the United States and in foreign jurisdictions. Although we enter into confidentiality agreements with our employees, consultants and strategic partners, and generally control access to and
distribution of our proprietary information, the steps we have taken to protect our intellectual property may not prevent misappropriation. In addition, we do not know whether we will be able to defend our proprietary rights since the validity,
enforceability and scope of protection of proprietary rights is still evolving.

Our efforts may not adequately protect our rights to the
extent necessary to sustain any competitive advantage we may have. Despite our efforts to protect our intellectual property, we may experience:



| |  |  | unauthorized use of our technology by competitors;
| | - |  | --------------------------------------------------



| |  |  | independent development of the same or similar technology by a competitor, coupled with a lack of enforceable patents on our part;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------



| |  |  | failure of our pending patent applications to result in issued patents;
| | - |  | -----------------------------------------------------------------------



| |  |  | successful interference actions to our patents, successful patent infringement lawsuits or successful oppositions to our patents and patent applications;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | unauthorized disclosure or use of our proprietary information by former employees or affiliates; and
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | failure by our commercial partners to comply with their obligations to share technology or use our technology in a limited manner.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------

Policing unauthorized use of our intellectual property is difficult, costly and time-intensive. We may fail to prevent misappropriation of our
technology, particularly in countries where the laws may not protect our proprietary rights to the same extent as do the laws of the United States. If we cannot prevent other companies from using our proprietary technology or if our patents are
found invalid or otherwise unenforceable, we may be unable to compete effectively against other manufacturers of ultrasound systems, which could decrease our market share.

Changes in the healthcare industry could result in a reduction in the size of the market for our products or may
require us to decrease the selling price for our products, either of which could have a negative impact on our financial performance.

Trends toward managed care, healthcare cost containment, and other changes in government and private sector initiatives in the United States and other countries in which we do business are placing increased emphasis on lowering the cost of
medical therapies, which could adversely affect the demand for or the prices of our products. For example:



| |  |  | major third-party payers of hospital and non-hospital based healthcare services, including Medicare, Medicaid and private healthcare insurers, are considering
revising their payment methodologies which may result in stricter standards for reimbursement of imaging charges and/or lower or more bundled payment;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | numerous legislative proposals have been considered that would result in major reforms in the U.S. and foreign healthcare systems that could harm our business;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | there has been a consolidation among healthcare facilities and purchasers of medical devices in the United States and foreign countries who prefer to limit the
number of suppliers from whom they purchase medical products, and these entities may decide to stop purchasing our products or demand discounts on our prices;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | there is economic pressure to contain healthcare costs in worldwide markets; and
| | - |  | --------------------------------------------------------------------------------



| |  |  | there are proposed and existing laws and regulations in domestic and international markets regulating pricing and profitability of companies in the healthcare
industry.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------

These trends could lead to pressure to reduce prices for our products and could cause a decrease in the size
of the market that could adversely affect our revenue and profitability, which could harm our business.

If healthcare reimbursement policies place
limits on which providers may receive payment for imaging services or substantially reduce reimbursement amounts or coverage for specific procedures, market acceptance of our products may be reduced.

Continued demand for our products depends in part on the extent to which our customers receive reimbursement for the use of our products from third-party
payers such as Medicare, Medicaid and private health insurers (and equivalent third-party payers in foreign countries). Presently, reimbursement policies for physician-performed diagnostic imaging services are fairly unrestricted in the United
States and payment levels are sufficient to enable providers to recoup the costs of purchasing ultrasound systems. The continuing efforts of governmental authorities, private health insurers and other third-party payers to contain or reduce the
costs of healthcare could, however, result in reduced payment for imaging services or more restrictive payment policies for diagnostic imaging.

As an example, a Medicare payment policy arising from the Deficit Reduction Act of 2005, caps payments to physician offices and freestanding imaging centers for the technical component of most imaging services. Although reimbursement
amounts for most ultrasound procedures were not lowered by this payment policy, vascular ultrasound examinations are now being paid at a lower rate than they were previously. In markets in which the use of ultrasound continues to be an emerging
standard of care, additional payment rate cuts such as this one could dampen market demand for ultrasound equipment.

Some private insurers
have implemented imaging privileging programs as a means of controlling utilization of imaging services. For example, Highmark Blue Cross Blue Shield, a private insurer operating in Pennsylvania, requires that providers meet specific criteria in
order to receive payment for imaging services provided to its subscribers. These criteria, in some instances, exclude some providers by virtue of their clinical specialty. Other criteria require providers to obtain specific credentials from
third-party accreditation organizations. Policies such



17



---

##### Table of Contents

as these, if they were to be more widely adopted by third party payers, could have a negative impact on the ability of customers to receive reimbursement for
ultrasound services they provide their patients and, in turn, could dampen demand for our products.

In addition, future congressional
legislation related to the Medicare program may include the requirement that non-physician sonographers obtain a credential from third-party credentialing organizations in order to provide ultrasound service under the program. Such legislation may
also include the requirement that physician offices which provide imaging services be accredited through a third-party accreditation organization. These policies, which would increase the regulation of providers, could restrict the potential new
users for our products and, in turn, limit our ability to grow our business.

Finally, both governmental and private third-party payers are
calling for increasing levels of evidence of beneficial clinical outcomes and cost effectiveness in addition to proof of clinical efficacy as a prerequisite to granting coverage for new technologies and devices and new applications for existing
technologies. To the extent that services performed with current or future products that we may bring to market are not described by existing Current Procedural Terminology codes or are not covered under existing coverage policies, there is a risk
that reimbursement for these applications may not be attained at all or within a reasonable timeframe. For example, carotid intima media thickness measurement, which is an application of ultrasound performed by our SonoCalc IMT software, is not
currently reimbursed by Medicare and is not a part of third-party payers standard benefits packages.

We may be unable to predict our sales and
plan manufacturing requirements with accuracy, which may adversely affect our operating results.

Our customers typically order products
on a purchase order basis. In some circumstances, customer orders may be cancelled, changed or delayed on short notice. Lack of significant order backlog makes it difficult for us to forecast future sales with certainty and could result in over or
under production, which could lead to higher expense, lower than anticipated revenue, and reduced gross margin. Varying quarterly demands from our customers, particularly as we introduce new products, also make it difficult to accurately forecast
component and product requirements, exposing us to the following risks:



| |  |  | If we overestimate our requirements, we may be obligated to purchase more components or third-party products than we need; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------



| |  |  | If we underestimate our requirements or experience shortages of product components from time to time, we could experience an interruption in revenue, because our
third-party manufacturers and suppliers may have an inadequate product or product component inventory to satisfy our requirements.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The final assembly and testing of our products is done at our Bothell, Washington factory where we integrate different components manufactured by various suppliers. If we encounter supplier, regulatory, engineering or
technical difficulties in manufacturing on account of events at our factory or our suppliers factories, we may incur delays in delivery of these products to customers and that could adversely affect our revenues.

If our suppliers, including our single-source suppliers, fail to supply us with the components that we need to manufacture our products on a timely basis, we could
experience production delays, cost increases and lost sales.

We depend on suppliers, including some single-source suppliers, to provide
highly specialized parts, such as custom-designed integrated circuits, cable assemblies and transducer components. We also depend on single-source suppliers to provide other components, such as image displays, batteries, capacitors and cables. We do
not maintain significant inventories of certain components, and may experience an interruption of supply if a supplier



18



---

##### Table of Contents

is unable or unwilling to meet our time, quantity and quality requirements. There are relatively few alternative sources of supply for some of these
components. An increase in demand for some parts by other companies could also interrupt our supply of components. We have in the past experienced supply problems in timeliness and quality, but to date these problems have not resulted in lost sales
or lower demand. Nevertheless, if we experience an interruption of supply or are required to switch suppliers, the manufacture and delivery of our products could be interrupted, our manufacturing costs could substantially increase and we could lose
substantial amounts of product sales.

In addition, our circuit boards are produced in Thailand by one of the worlds largest
electronic manufacturing services suppliers. These circuit boards are highly customized and securing a different source of supply for this critical component of our product would be particularly difficult. If we experience delays in the receipt or
deterioration in product yields of these critical components, we may experience delays in manufacturing or an increase in costs resulting in lost sales or a deterioration in gross margin.

If we are unable to overcome the risks inherent in international business activities, the growth of our business will be limited and our profitability will decline.

We have ten wholly owned subsidiaries located in the United Kingdom, France, Germany, Italy, India, Spain, Japan, Canada, Australia and
China. The percentage of our total revenue originating outside the United States equaled 49%, 48% and 46% for the years ended December 31, 2007, 2006 and 2005, respectively. Successful maintenance of these international operations requires us
to:



| |  |  | maintain an efficient and self-reliant local infrastructure;
| | - |  | ------------------------------------------------------------



| |  |  | continue to attract, hire, train, manage and retain qualified local sales and administrative personnel;
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | continue to identify new non-U.S. distributors and maintain our relationship with our existing distributor;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | comply with diverse and potentially burdensome local regulatory requirements and export laws, including license requirements, trade restrictions and tariff
increases; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | maintain complex information, financial, distribution and control systems.
| | - |  | --------------------------------------------------------------------------

Our presence in international markets has required, and will continue to require, substantial financial and managerial resources. The costs of
maintaining our presence in international markets are unpredictable, difficult to control and may exceed budgeted amounts. In addition, we may be subject to the following conditions in countries where we conduct our operations:



| |  |  | adverse regional political or economic conditions;
| | - |  | --------------------------------------------------



| |  |  | currency exchange rate fluctuations;
| | - |  | ------------------------------------



| |  |  | difficulty in enforcing any judgment against non-U.S. distributors or other third parties upon which our business is heavily dependent; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | reduced protection for our intellectual property rights.
| | - |  | --------------------------------------------------------

Despite our expenditures and efforts internationally to mitigate the challenges above, we may not continue to generate a proportional substantial increase in international revenue, and such a deficiency would impair
our operating results.

Currency exchange rate fluctuations in various currencies in which we do business and longer receivables collection
periods outside of the United States could adversely affect our business.

Total sales denominated in a currency other than USD were
$62.8 million, or 31% of our total consolidated revenues for the year ended December 31, 2007. As a result, our results of operations could be adversely affected by certain movements in exchange rates. Although we take steps to hedge a
substantial portion of our foreign currency exposures, there is no assurance that our hedging strategy will be successful or that the hedging markets will have sufficient liquidity or depth for us to implement our strategy in a cost effective
manner.

Additionally, as of December 31, 2007, 60% of our accounts receivable balance was from international customers, of which 58%,
or $21.4 million, was denominated in a currency other than USD. Although we regularly review our receivable positions in foreign countries for any indication that collection may be at risk, our revenue from international sales may be adversely
affected by longer receivables collection periods and greater difficulty in receivables collection.

If we, or our suppliers, fail to comply with U.S.
and foreign governmental regulations applicable to our products and manufacturing practices, we could experience product introduction delays, production delays, cost increases and lost sales and our future revenues may be adversely affected.

Our products, our manufacturing and marketing activities, and the manufacturing activities of our third-party medical device manufacturers
are subject to extensive regulation by a number of governmental agencies, including the FDA, and comparable international agencies. We and our third-party manufacturers are or may be required to:



| |  |  | obtain prior clearance or approval from these agencies before we can market and sell our products;
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | undergo rigorous inspections by domestic and international agencies; and
| | - |  | ------------------------------------------------------------------------



| |  |  | satisfy content requirements for all of our sales and promotional materials.
| | - |  | ----------------------------------------------------------------------------

The process for obtaining regulatory approval can be lengthy and expensive, and the results are unpredictable. If we are unable to obtain clearances or
approvals needed to market existing or new products, or obtain such clearances or approvals in a timely manner, our revenues and profitability could be adversely affected. Moreover, clearances and approvals, if granted, may limit the uses for which
a product may be marketed, which could reduce or eliminate the commercial benefit of manufacturing any such product.

To ensure that
manufacturers adhere to good manufacturing practices, medical device manufacturers are routinely subject to periodic inspections by the FDA and may be inspected by foreign regulatory agencies from countries in which we do business. In addition, BSI
performs periodic assessments of our manufacturing processes and quality system. Compliance with the regulations of various agencies, including the Environmental Protection Agency and the Occupational Safety and Health Administration, may require us
to incur substantial costs and may delay or prevent the introduction of new or improved products. Although to date these actions by regulatory bodies have not required us to incur substantial costs or delay product shipments, we expect to experience
further inspections and incur additional costs as a result of governmental regulation.

Failure to comply with applicable regulatory
requirements can result in enforcement action, including product recall, the issuance of fines, injunctions, civil and criminal penalties, detaining or banning our products, and operating restrictions. Our third-party medical device manufacturers
may also be subject to the same sanctions if they fail to comply with the laws and regulations and, as a result, may fail to supply us with components required to manufacture our products.

A failure to manage our growth could impair our ability to achieve our business objectives.

We have experienced rapid and substantial growth in recent years. Our revenue increased to $205.1 million in 2007 from $171.1 million in 2006 and $147.5
million in 2005. Our growth could strain our existing management, operational and financial resources and, if we are unable to manage this growth successfully, our business and financial performance will be adversely affected. In order to manage our
growth effectively, we will need to expand our sales, manufacturing and quality assurance staff, and improve the productivity and efficiency of our existing operational, financial, international support staff and our management and information
systems. We may be unable to hire and retain the personnel necessary to operate and expand our business. We also may be unable to increase the productivity and efficiency of our existing resources.

Our reliance on a single manufacturing facility may expose us to enhanced risk from natural disasters or other unforeseen catastrophic events.

Our manufacturing facilities are located in two buildings in Bothell, Washington, in close proximity to each other. Despite precautions taken by us, a
natural disaster such as an earthquake or other unanticipated catastrophic events at this location could significantly impair our ability to manufacture our products and operate our business. Our facilities and certain manufacturing equipment would
be difficult to replace and could require substantial replacement lead-time. Such catastrophic events may also destroy any inventory of product or components. While we carry insurance for natural disasters and business interruption for our Bothell
facilities, the occurrence of such an event could result in losses that exceed the amount of our insurance coverage, which would impair our financial results.

We may incur greater than expected warranty expense.

We expect our warranty liability and expense to continue to increase
significantly due to the five-year warranty offered with the MicroMaxx system, M-Turbo system, and S Series ultrasound tools. Should actual failure rates and repair or replacement costs differ from our estimates, additional warranty expense may be
incurred and our financial results may be materially affected.

The loss of key employees or management personnel could impair our ability to achieve
our business objectives and negatively affect our financial results.

Our success depends heavily on our ability to retain the services
of certain key employees or certain technical expertise. Competition among medical device companies for qualified employees is intense. We may fail to retain these key employees, and we may fail to attract qualified replacements if they do leave. We
do not maintain key-person insurance on any of our employees. We do not have employment agreements with any of our employees except for employees in certain countries outside the United States and change in control agreements with certain members of
senior management. The loss of any of our key employees could significantly delay or prevent the achievement of our product development or business objectives.

In addition, our future success will depend, to a significant extent, on the ability of our management to operate effectively, both individually and as a group. We must successfully manage transition and replacement
issues that may result from the departure or retirement of members of our senior management. Transitions of management personnel may cause disruption to our operations or customer relationships, or a decline in our financial results.

Our results of operations are subject to significant quarterly variation.

Our quarterly operating results may vary significantly due to a combination of factors, many of which are beyond our control. These factors include:



| |  |  | the timing of new product introductions by us or our competitors;
| | - |  | -----------------------------------------------------------------



21



---

##### Table of Contents

| |  |  | the timing of regulatory approvals;
| | - |  | -----------------------------------



| |  |  | the timing of orders from major customers and distributors, including bulk orders from governmental entities and demo orders from new distributors;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | seasonal buying patterns of our customers;
| | - |  | ------------------------------------------



| |  |  | development and promotional expenses relating to new product introductions;
| | - |  | ---------------------------------------------------------------------------



| |  |  | the revenue mix by product and geography;
| | - |  | -----------------------------------------



| |  |  | changes in pricing policies by us or our competitors;
| | - |  | -----------------------------------------------------



| |  |  | fluctuations in foreign exchange rates;
| | - |  | ---------------------------------------



| |  |  | writeoffs resulting from obsolete inventory;
| | - |  | --------------------------------------------



| |  |  | fluctuations in our effective tax rates;
| | - |  | ----------------------------------------



| |  |  | our ability to meet demand for our products;
| | - |  | --------------------------------------------



| |  |  | the market acceptance of our products;
| | - |  | --------------------------------------



| |  |  | legal costs and the results of litigation;
| | - |  | ------------------------------------------



| |  |  | changes in distribution channels; and
| | - |  | -------------------------------------



| |  |  | the ability of our sales force to effectively market and sell our products.
| | - |  | ---------------------------------------------------------------------------

Accordingly, our quarterly sales and operating results may vary significantly in the future, and period-to-period comparisons of our results of
operations may not be meaningful and should not be relied upon as indicators of future performance.

Seasonality and concentration of revenues at the
end of the quarter could cause our revenues to fall below the expectations of securities analysts and investors, resulting in a decrease in our stock price.

As a result of customer buying patterns and the efforts of our sales force to meet or exceed quarterly and year-end quotas, historically we have earned a substantial portion of each years revenues during the
last quarter and a substantial portion of each quarters revenues during its last month. If expected revenues at the end of any quarter are delayed, our revenues for that quarter could fall below the expectations of securities analysts and
investors, resulting in a decrease in our stock price.

Product liability and other claims and product field actions initiated against us could increase
our costs, delay or reduce our sales and damage our reputation, adversely affecting our financial condition.

Our business exposes us to
the risk of product liability, malpractice or warranty claims inherent in the sale and support of medical device products, including those based on claims that the use or failure of one of our products resulted in a misdiagnosis or harm to a
patient. Such claims may cause financial loss, damage our reputation by raising questions about our products safety and efficacy, and could interfere with our efforts to market our products. Although to date we have not been involved in any
medical malpractice or product liability litigation, we may incur significant liability if such litigation were to occur. We may also face adverse publicity resulting from product field actions or regulatory proceedings brought against us. Although
we currently maintain liability insurance in amounts we believe are commercially reasonable, any product liability we incur may exceed our insurance coverage. Liability insurance is expensive and may cease to be available on acceptable terms, if at
all. A product liability or other claim or product field action not covered by our insurance or exceeding our coverage could significantly impair our financial condition. In addition, a product field action or a liability claim against us could
significantly harm our reputation and make it more difficult to obtain the funding and commercial relationships necessary to maintain our business.

We may be unable to sustain or increase our profitability.

Prior to 2004, we had incurred losses in each year since our inception in 1998. As of December 31, 2007, we had an accumulated deficit of $44.9
million. We achieved profitability in 2004 and were profitable in 2005, 2006 and 2007, but we may be unable to sustain or increase future profitability on a quarterly or annual basis. We may incur losses if we cannot increase or sustain our revenue.
We expect that our operating expenses will increase in the foreseeable future as we expand our product development activities, our sales and marketing infrastructure, our administrative support and our product offerings. Additionally, we expect
operating expenses would increase as we pursue the acquisition of companies or technologies to further our growth. Our expansion and acquisition efforts, to be successful, may require more funding than we currently anticipate.

Accordingly, we will need to generate significant additional revenue in the future in order to be able to sustain or increase profitability. If we cannot
generate sufficient revenue to sustain or increase our profitability, then our business will be adversely affected.

Our investment securities may be
adversely impacted by economic factors beyond our control and we may incur additional impairment charges to our investment portfolio.

As of December 31, 2007, we had $12.6 million in Columbia Strategic Cash Portfolio, which is in the process of liquidation. In our judgment this investment, which is classified as a money market account, has a decline in fair value
that is other than temporary, accordingly we have recognized an impairment loss of $0.2 million. Distributions from this portfolio are solely at the discretion of the portfolio manager. We anticipate that $11.3 million will be distributed from this
portfolio during 2008, which is recorded as a short-term investment, and $1.3 million will be distributed after 2008, which is recorded as a long-term investment.

The credit and capital markets deteriorated in 2007 and may continue to deteriorate in 2008. These markets may deteriorate further and we may incur additional impairments to our investment portfolio, which could
negatively affect our financial condition, cash flow and reported earnings.

Conversion of our convertible senior notes will dilute the ownership
interest of shareholders at the time of conversion.

Upon conversion of some or all of our senior notes the ownership interests of
shareholders may be diluted. Any sales in the public market of the common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock. In addition, the existence of the senior notes may encourage short
selling by market participants because the conversion of the notes could be used to satisfy short positions, or anticipated conversion of the notes into shares of our common stock could depress the price of our common stock.

In addition, if a fundamental change occurs, under certain circumstances we will adjust the conversion rate by a number of shares of our common stock for
notes converted in connection with such fundamental change. The adjustment to the conversion rate will be determined based on the date on which the fundamental change becomes effective and the price paid per share of our common stock in such
transaction, as described under the terms of the senior notes.

As more fully defined in the indenture applicable to the notes, a
fundamental change will be deemed to have occurred upon the consummation of certain significant corporate transactions, including for example, the acquisition by one party or group of more than 50% of the voting power of our common equity, the
consummation of certain recapitalizations, consolidations or mergers, the sale of all or substantially all of our assets, shareholder approval of our liquidation or dissolution, the failure of our common stock to be listed on any U.S. national
securities exchange or a change in the composition of our board of directors as a result of which our incumbent directors, or directors appointed by our incumbent directors, do not constitute a majority of our board.

Sales of a significant number of shares of our common stock in the public markets, or the perception of such sales,
could depress the market price of our common stock.

Sales of a substantial number of shares of our common stock or other
equity-related securities in the public markets could depress the market price of our common stock, and impair our ability to raise capital through the sale of additional equity securities. We cannot predict the effect that future sales of our
common stock or other equity-related securities would have on the market price of our common stock. The price of our common stock could be affected by possible sales of our common stock by investors who view the notes as a more attractive means of
equity participation in our company and by hedging or arbitrage trading activity, which we expect to occur involving our common stock. This hedging or arbitrage could, in turn, affect the market price of our common stock.

The convertible note hedge and warrant transactions associated with our convertible senior notes may affect the value of our common stock.

The convertible note hedge and warrant transactions associated with our convertible senior notes may affect the value of our common stock. In connection
with the pricing of our convertible senior notes, we entered into a convertible note hedge transaction with an option counterparty. We also entered into a warrant transaction with this option counterparty. The convertible note hedge transaction
covers approximately 42% of any converted notes, and is expected to reduce potential dilution to our common stock upon any such conversion. However, the warrant transaction could separately have a dilutive effect on our earnings per share to the
extent that the market value per share of our common stock exceeds the applicable strike price of the warrants.

In connection with
establishing its initial hedge of these transactions, the option counterparty or its affiliates:



| |  |  | entered into various derivative transactions with respect to our common stock concurrently with or shortly after the pricing of the notes; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | may enter into or unwind various derivative transactions with respect to our common stock and/or purchase or sell our common stock in secondary market transactions
following the pricing of the notes (and would likely do so during any observation period related to the conversion of the notes).
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

These activities could have the effect of increasing or preventing a decline in the price of our common stock concurrently with or shortly after the pricing of the notes and during any observation period related to a conversion of the
notes.

In addition, the option counterparty or its affiliates will likely modify its hedge position from time to time prior to conversion
or maturity of the notes by purchasing and selling our common stock, other of our securities or other instruments it may wish to use in connection with such hedging. In particular, such hedging activity would likely occur during any observation
period for a conversion of notes, which may have a negative effect on the value of the consideration received in relation to the conversion of those notes.

We intend to exercise options we hold under the convertible note hedge transaction whenever notes are converted. In order to unwind its hedge position with respect to those exercised options, the option counterparty
or its affiliates would expect to sell shares of our common stock in secondary market transactions or unwind various derivative transactions with respect to our common stock during the observation period for the converted notes. We have also agreed
to indemnify the option counterparties for losses incurred in connection with a potential unwinding of its hedge positions under certain circumstances.

The potential effect, if any, of any of these transactions and activities on the market price of our common stock will depend in part on market conditions and cannot be ascertained as of the date of this annual
report. Any of these activities could adversely affect the price of our common stock and, as a result, the value of the consideration and the number of shares of our common stock, if any, that the noteholders would receive upon the conversion of the
notes.

If we, or our independent registered public accounting firm, determine that we have material weaknesses in our
internal control over financial reporting, current and potential shareholders could lose confidence in our financial reporting, which could harm our business and the trading price of our stock.

We dedicated a significant amount of time and resources in an effort to ensure that we have appropriate internal controls over financial reporting for the
year ended December 31, 2007 and will continue to do so for future fiscal periods. We may encounter problems or delays in completing the review and evaluation, the implementation of improvements and the receipt of a positive attestation, or any
attestation at all, by our independent auditors. Additionally, managements assessment of our internal control over financial reporting may identify additional deficiencies that need to be addressed in our internal control over financial
reporting or other matters that may raise concerns for investors.

We may be unable to utilize our deferred tax assets, which could adversely affect our
future operating results.

In 2004, we recognized deferred tax assets relating to our U.S. operations on our balance sheet as a
non-recurring income tax benefit. In addition, in 2006, we recognized deferred tax assets relating to our international operations on our balance sheet as a non-recurring income tax benefit. The deferred tax assets primarily represent the income tax
benefit of the net operating losses we have incurred from our operations since inception. We will continue to evaluate our ability to utilize our deferred tax assets in future periods and record any resulting adjustments that may be required to
deferred income tax expense.

Our consolidated income tax rate may fluctuate as U.S. and international operations become more or less
profitable. We may be subject to higher tax in future periods.

If we fail to comply with our obligations in our license with ATL, we could lose license
rights that are important to our business.

We license certain technology from ATL that is incorporated into our single technology
platform, and we use this ATL technology in all of our HCU systems. A substantial majority of our revenue is attributable to products incorporating this ATL technology.

ATL may terminate our license in the event of an uncured material default by us in our obligations under the license agreement. The termination or other loss of our license to use ATL technology would significantly
impair our ability to manufacture, market and sell our products. If this license is terminated, we may be unable to generate sufficient revenue to maintain our business.

If we incur a tax liability in connection with our spin-off from ATL, we would be required to pay a potentially significant expense, which would diminish our financial resources.

Our spin-off was treated by ATL as a tax-free spin-off under Section 355 of the Internal Revenue Code of 1986, or the Code. If ATL were to recognize
taxable gain from the spin-off, the Internal Revenue Service, or IRS, could impose that liability on any member of the ATL consolidated group as constituted prior to the spin-off, including us. Generally, the IRS may assert that our spin-off from
ATL is a taxable transaction until the expiration of the statute of limitations applicable to ATL with respect to the spin-off transaction. The expiration of the statute of limitations with respect to the spin-off transaction depends upon the
actions and tax filings of ATL and the special rules applicable to spin-offs in general, which special rules could result in the extension of the general statute of limitations for an indefinite period of time. In the event of a tax liability, ATL
has agreed to cover 85% of any such liability, unless the tax is imposed due to our actions solely or by ATL solely, in which case, we have agreed with ATL that the party who is solely at fault shall bear all of the tax liability. We are unaware of
any actions that would result in a tax liability to us under the indemnity agreement regarding the spin-off transaction. We are aware that ATL was acquired in a transaction subsequent to the spin-off transaction,

which could potentially result in the spin-off being treated as a taxable transaction, but which resulting tax liability in our view would be the sole
responsibility of ATL pursuant to our agreement with ATL. ATL may refuse, however, to indemnify us for a tax liability arising out of the spin-off transaction or may argue that it did not cause the tax liability to be imposed. In such event, we may
incur a significant expense for all or a portion of the taxes related to the spin-off.

Our articles of incorporation, bylaws, rights plan and
Washington law contain provisions that could discourage a change in control.

Certain provisions of our restated articles of
incorporation and bylaws, our shareholder rights plan and Washington law would make it more difficult for a third party to acquire us, even if doing so would be beneficial for our shareholders. This could limit the price that certain investors might
be willing to pay in the future for shares of our common stock. For example, certain provisions of our articles of incorporation or bylaws:



| |  |  | allow our board to issue preferred stock without any vote or further action by the shareholders;
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | limit the right of shareholders to act by written consent without a meeting;
| | - |  | ----------------------------------------------------------------------------



| |  |  | eliminate cumulative voting in the election of directors by holders of our common stock; and
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | specify a minimum threshold for shareholders to call a special meeting.
| | - |  | -----------------------------------------------------------------------

We have adopted a shareholder rights plan, which is triggered upon commencement or announcement of a hostile tender offer or when any one person or group
acquires 20% or more of our common stock. Once triggered, the rights plan would result in the issuance of preferred stock to the holders of our common stock other than the acquirer. In November 2007, we renewed this plan until April 5, 2013.

We are also subject to certain provisions of Washington law that could delay or make more difficult a merger, tender offer or proxy
contest involving us. In particular, Chapter 23B.19 of the Washington Business Corporation Act prohibits corporations incorporated in Washington from engaging in certain business combinations with any interested shareholder for a period of five
years unless specific conditions are met.

These provisions of our restated articles of incorporation, bylaws and rights plan and
Washington law could have the effect of delaying, deferring or preventing a change in control of us, including, without limitation, discouraging a proxy contest or making more difficult the acquisition of a substantial block of our common stock. The
provisions could also limit the price that investors might be willing to pay in the future for shares of our common stock.

None.



|ITEM 2. | PROPERTIES
|------- | ----------

Our principal offices are located in
Bothell, Washington, where we lease two buildings totaling approximately 125,000 square feet. These facilities include approximately 78,000 square feet of office space and 47,000 square feet of manufacturing and warehouse space. The leases run
through 2014. Additionally, we lease smaller office facilities at foreign locations in which we have operations.



|ITEM 3. | LEGAL PROCEEDINGS
|------- | -----------------

We filed a patent infringement
suit against Zonare Medical Systems, Inc. in the federal district court of the Central District of California alleging that Zonare infringed one of our key patents through sales of its z.one ultrasound system. On March 14, 2007, Zonare filed an
answer to our claim which included a counterclaim against us alleging that our products infringe its patent related to its portable docking station.

On May 15, 2007, GE Healthcare, a competitor of ours, filed a lawsuit against us in the federal
district court in the Western District of Wisconsin. The lawsuit alleges that our MicroMaxx and/or TITAN products willfully infringe certain of GEs U.S. patents relating to ultrasound technology. GE is seeking unspecified monetary damages and
an injunction. On July 5, 2007, we filed a counterclaim against GE and certain of its affiliates. In parallel, we filed our answer to the complaint denying all of GEs claims and alleging that the asserted patents are either invalid, not
infringed, or both. Subsequent to these initial filings, both parties supplemented their claims with additional allegations of patent infringement. Our complaint also seeks unspecified monetary damages and a court injunction against future
infringement by GE and its affiliates.

|ITEM 7. | MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
|------- | -------------------------------------------------------------------------------------

Overview

We are the world leader in hand-carried ultrasound, or HCU, systems. We specialize in the
development of HCU systems for use in a variety of medical specialties in a range of clinical settings at the point-of-care. Our proprietary technologies have enabled us to design HCU systems that combine high resolution, all-digital, broadband
imaging with advanced features and capabilities typically found on cart-based ultrasound systems. We believe that the performance, size, durability, ease of use and cost-effectiveness of our products are expanding existing ultrasound markets, and
are opening new markets by bringing ultrasound visualization out of the imaging lab to the point-of-care such as the patients bedside or the physicians examining table for diagnosis and procedural guidance.

The large size, weight and complexity of traditional cart-based ultrasound systems typically require a physician or highly trained clinician to perform
the examination in a centralized imaging department, such as a hospitals radiology department. Our strategic intent is to enable clinicians to use ultrasound in a variety of clinical settings by developing each potential market based on three
fundamental tenets: (i) the design of high performance system hardware, software and transducers with application-specific settings and capabilities; (ii) the provision of educational training that ensures appropriate use of the equipment
in the clinical setting; and (iii) the support of professional institutions and ultrasound thought leaders in the completion of use protocols and clinical research that accelerates the adoption of HCU to improve patient outcomes. By providing
ultrasound at the primary point-of-care, our systems expedite diagnosis and treatment in acute and critical care settings and provide visual guidance for interventional procedures. In outpatient settings, our systems can eliminate delays associated
with the outpatient referral process. This increased accessibility is changing clinical practice, improving patient care and safety and has the potential to reduce healthcare costs through earlier diagnosis of diseases and conditions.

We design our products for applications where ultrasound has not typically been used such as emergency medicine, surgery, critical care, internal
medicine and vascular access procedures as well as for imaging in traditional applications, such as radiology, cardiology, vascular medicine and obstetrics and gynecology (OB/Gyn). In addition, the U.S. military has successfully deployed
our systems in traditional hospital settings, field hospitals and forward surgical teams in war zones and areas of conflict. We began shipping our first products in September 1999 and today have an installed base of thousands of systems worldwide.

Our fourth generation product platform is the basis of two product lines, the M-Turbo (TM) system and the S Series (TM) ultrasound tools,
which we introduced in October 2007. These products together with the MicroMaxx (R) system, our third generation of hand-carried technology and introduced in 2005, offer a broad-based product portfolio for hospital and physician office markets.
Based on our proprietary Application Specific Integrated Circuit (ASIC) technology for high-resolution ultrasound imaging these systems offer image resolution comparable to costly, conventional cart-based ultrasound systems weighing over
200 pounds. A five-year warranty covering the system and most of the transducers, comes standard with these products.

Our second
generation product, the TITAN (R) system, began shipping in 2003. This system addresses point-of-care and traditional ultrasound markets. Our first generation of products includes the 180 (TM) and iLook (R) series. The SonoSite 180PLUS
(TM) system is designed for general ultrasound imaging and the SonoHeart (R) ELITE is specifically configured for cardiovascular applications. The iLook 25 imaging tool is designed to provide visual guidance for physicians and nurses while
performing vascular access procedures and the iLook 15 imaging tool is designed to provide imaging of the chest and abdomen.

We currently
face competition from companies that manufacture cart-based and portable ultrasound systems. Many of our competitors are larger and have greater resources than we do and offer a range of products

broader than our products. The dominant competitors in this industry are GE Healthcare, a unit of General Electric Company, Siemens Medical Solutions, or
Siemens, and Philips Medical Systems, a division of Koninklijke Philips Electronics, N.V., or Philips. In addition, as the market for high-performance, HCU systems develops, we expect competition to increase as potential and existing competitors
enter the portable market or modify their existing products to more closely approximate the combined portability, quality, performance and cost of our products. Our current competitors in the portable market include GE Healthcare, Siemens, Philips,
Biosound Esaote, Inc., Medison America Inc., a subsidiary of Medison Company, Ltd., or Medison America, Terason, a division of TeraTech Corporation, or Terason, and Zonare Medical Systems, Inc., a privately held company, or Zonare.

We commenced operations as a division of ATL Ultrasound, Inc., or ATL. On April 6, 1998, we became an independent, publicly owned company through a
distribution of one new share of our stock for every three shares of ATL stock held as of that date. ATL retained no ownership in SonoSite following the spin-off.

Critical Accounting Policies and Estimates

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 U.S. generally accepted accounting principles. The preparation of these consolidated financial statements requires us to make estimates and judgments
that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to product returns, bad debts,
inventories, investments, warranty obligations, service contracts, contingencies and litigation. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances. The results form
the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Our critical accounting policies and estimates include accounts receivable, revenue recognition, valuation of investments and inventories, goodwill,
intangible assets, warranty expense, income taxes, stock-based compensation, our convertible note and hedge transaction and acquisitions.

Accounts receivable. We maintain an allowance for estimated losses resulting from the inability of our customers to make required payments. We determine the adequacy of this allowance by regularly reviewing the aging of our accounts
receivable and evaluating individual customer receivables, considering customers financial condition, historical experience, credit history and current economic condition. Losses can be difficult to anticipate. An increase in losses beyond
those expected by management would reduce earnings when they become probable or as the estimated loss increases.

Revenue
recognition. We recognize revenue on products and accessories when goods are shipped under an agreement with a customer, risk of loss and title have passed to the customer, sales returns are estimable and collection of any resulting receivable
is reasonably assured. For service contracts, revenue is recognized as services are provided or over the term of the contract. Revenue is recorded net of estimated returns. We estimate returns by reviewing our historical returns, considering
customer reaction to new product introductions and current economic conditions. Sales discounts are recorded as a reduction in revenue. We separately price and sell product upgrades to our customers.

Sales to distributors are generally made pursuant to standard distributor agreements. We recognize revenue when title and risk of loss have transferred
to the distributor. Our only significant post-shipment obligation to distributors is our product warranty covering materials and workmanship (see Warranty expense below). The distributor can only reject products for an obvious defect or
shipping error, generally within 30 days of receipt, and in such cases, replacement products would be sent. Since the distributors remedy is the replacement of the product and not a refund or credit, we do not defer revenue associated with
these sales. Costs associated with the



32



---

##### Table of Contents

repair of returned, defective products are captured in our warranty accrual. Our standard distributor arrangements do not have any other return provisions.

Our sales arrangements may contain multiple elements, which include hardware and software products. Revenue from the sale of software,
software-related elements, and hardware when the software elements are more than incidental to the product as a whole, is recognized in accordance with software revenue recognition rules. We have vendor specific objective evidence (VSOE)
of fair value for our products. Accordingly, for transactions that have undelivered elements for which we have VSOE of the elements, revenue equal to the total fair value of the undelivered elements is deferred and is not recognized until the
element is delivered to the customer. When the undelivered element represents services under extended service contracts, revenue equal to the stated price is deferred and recognized evenly over the contract term as those services are provided.

Investments. Our investment securities primarily consist of high-grade U.S. government or corporate debt and high-grade
asset-backed securities. We have the ability to hold our securities until maturity, however, we classify all securities as available-for-sale, as the sale of such securities may be required prior to maturity to implement management strategies. These
securities are carried at fair value, with the unrealized gains and losses generally reported as a component of other comprehensive income (loss) until realized. Realized gains and losses from the sale of available-for-sale securities, if any, are
determined on a specific identification basis.

A decline in market value of any available-for-sale security below cost that is determined
to be other than temporary results in a revaluation of its carrying amount to fair value. The impairment is charged to earnings and a new cost basis for the security is established. Premiums and discounts are amortized or accreted over the life of
the related security as an adjustment to yield using the effective interest method. Interest income is recognized when earned. We may incur unrealized losses due to changes in market value attributable to changes in interest rates. Generally we have
the ability and intent to hold our investments until a recovery of cost, which may be maturity.

Valuation of inventories.
Inventories are stated at the lower of cost or market on a first-in, first-out method. Included in our inventories balance are demonstration products used by our sales representatives and marketing department. Adjustments to reduce carrying costs to
their net realizable values are recorded for obsolete material, shrinkage, earlier generation products and used or refurbished products held either as saleable inventory or as demonstration product.

We make judgments regarding the carrying value of our inventories based on current market conditions. Market conditions may change depending upon
competitive product introductions, consumer demand and reimbursement criteria in the medical community. If market conditions change or if the introduction of new products by us impacts the market for our previously released products, we may be
required to further write down the carrying cost of our inventories.

Goodwill. Goodwill represents the excess of cost of businesses
acquired over the estimated fair value of net assets acquired. We test goodwill for impairment on an annual basis, or more frequently if circumstances dictate. Application of the goodwill impairment test requires judgment, including the
identification of reporting units, assigning assets and liabilities to reporting units, assigning goodwill to reporting units, and determining the fair value of each reporting unit. Changes in these estimates and assumptions could potentially result
in recognition of an impairment of goodwill, which would be reflected as a loss on our consolidated statement of operations and as a reduction in the carrying value of goodwill.

Intangible Assets. Our intangible assets are comprised primarily of acquired technologies, non-compete agreements and reacquired distribution
rights. We use our judgment to estimate the fair value of each of these intangible assets. Our judgment about fair value is based on our expectation of future cash flows and an appropriate discount rate. We also use our judgment to estimate the
useful lives of each intangible asset. With



33



---

##### Table of Contents

respect to definite lived intangible assets, we evaluate the remaining useful lives and whether there are any indicators of impairment as circumstances
dictate. Indefinite-lived intangible assets are tested for impairment annually, or more frequently if circumstances dictate. If we conclude that any intangible asset is impaired, we would record this as a loss on our consolidated statement of
operations and as a reduction to the intangible asset.

Warranty expense. We accrue estimated warranty expense at the time of sale
for costs expected to be incurred under our product warranties. This provision for warranty expense is made based upon our historical product failure rates and service repair costs using managements judgment. We have limited history with some
of our products. We provide, with certain exceptions, a five-year warranty with the MicroMaxx system, M-Turbo system and S Series ultrasound tools. Given the length of the warranty period, the warranty liability for these systems is more difficult
to estimate than it has been for our other products that have a one-year warranty. However, given the similarity of the components used in the M-Turbo system and S Series ultrasound tools compared with our MicroMaxx system and the historical product
failure rate and service repair costs of the MicroMaxx and the other systems, we believe that we can reasonably estimate the amount of the warranty liability for these products. We expect our warranty liability and expense to continue to increase
significantly due to the five-year warranty offered with these products. Should actual failure rates or repair or replacement costs for any of our products differ from estimates, revisions to the estimated warranty liability may be required and our
results may be materially affected.

Income taxes. The process of accounting for income taxes involves calculating our current tax
obligation or refund and assessing the nature and measurements of temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences, and our net operating loss (NOL) and credit
carryforwards, result in deferred tax assets and liabilities. In each period, we assess the likelihood that our deferred tax assets will be recovered from existing deferred tax liabilities or future taxable income in each jurisdiction. To the extent
we believe that we would not meet the test that recovery is more likely than not, we would establish a valuation allowance. To the extent that we establish a valuation allowance or change this allowance in a period, we would adjust our
tax provision or tax benefit in the consolidated statement of operations. We use our judgment to determine our provision or benefit for income taxes, including estimates associated with uncertain tax positions and any valuation allowance recorded
against our deferred tax assets based on the weight of all positive and negative factors, including cumulative trends in profitability.

We
have accumulated U.S. federal and state income tax NOL carryforwards, foreign NOL carryforwards, research and experimentation tax credit carryforwards and alternative minimum tax credit carryforwards. In the fourth quarter of 2006, we reversed the
valuation allowance on a deferred tax asset on our balance sheet primarily representing NOLs from our international operations. Previously, we had recorded a valutation allowance against deferred tax assets on our balance sheet until it was
more likely than not that the tax assets related to either our U.S. or international operations would be realized. We assess our ability to utilize our NOL and tax credit carryforwards in future periods and record any resulting
adjustments that may be required to deferred income tax expense. In addition, we reduce the deferred income tax asset for the benefits of NOL and tax credit carryforwards utilized currently. The future impact on net income may therefore be positive
or negative, depending on the net result of such adjustments and charges.

Based upon a review of historical operating performance through
2007, and our expectation that we will generate profits in the U.S. and our international operations in the foreseeable future, we continue to believe it is more likely than not that the U.S. and international deferred tax assets will be fully
realized.

Stock-Based Compensation. On January 1, 2006, we adopted SFAS No. 123R, Share-Based Payment
(SFAS 123R), using the modified prospective transition method. SFAS 123R requires entities to recognize compensation expense for awards of equity instruments to employees based on the grant-date fair value of those awards (with limited
exceptions). For stock options, we utilize the Black-Scholes option pricing model to estimate the fair value of employee stock-based compensation at the date of grant, which requires the input of subjective assumptions, including expected
volatility, expected life and expected forfeitures. We estimate



34



---

##### Table of Contents

volatility by considering our historical stock volatility. We estimate expected term based on historical trends. Further, we estimate future forfeitures for
both stock options and RSUs granted, which are not expected to vest. We estimate forfeitures using historical employee turn-over rates as well as our judgment of future forfeitures. Our estimates of forfeitures will be adjusted over the requisite
service period based on the extent to which actual forfeitures differ, or are expected to differ, from our estimate.

Changes in these
inputs and assumptions can materially affect the measure of estimated fair value of our stock-based compensation. These assumptions are subjective and generally require significant analysis and judgment to develop. When estimating fair value, some
of the assumptions will be based on, or determined from, external data and other assumptions may be derived from our historical experience with stock-based payment arrangements. The appropriate weight to place on historical experience is a matter of
judgment, based on relevant facts and circumstances. In addition, future grants of equity awards will result in additional compensation expense in future periods.

Convertible debt and hedge transaction.We have recorded our senior convertible note as debt. The conversion option met the criteria, in our judgment, to preclude recognition as a debt discount. If the
conversion option had been recognized as a debt discount, it would have been recognized as additional interest expense over the term of the notes. Accordingly, our interest expense is based upon the stated rate. Additionally, we recorded the call
option and warrant transactions as equity instruments since our judgment is that they met the existing criteria. If the call option and warrant transactions had not met the criteria, then the instruments would have been recorded as assets or
liabilities and any changes in the fair values would be recognized in the consolidated income statement.

Acquisitions. The process
of accounting for an acquisition involves determining whether a business or assets were acquired, then assigning the cost to the fair value of the assets acquired. In our judgment we acquired assets when we purchased LumenVu, Inc. in July 2007,
rather than a business. Additionally, we determined that the acquired technology did not represent in-process research and development, which would have been expensed upon acquisition rather than capitalized as an intangible asset.

Results of Operations

Revenue

Revenue increased to $205.1 million in 2007, compared to $171.1 million in 2006 and $147.5 million in 2005. The increase in 2007 compared to 2006 was
attributable to the introduction of new products in Q4 and increased sales of MicroMaxx systems offset by a reduction in sales of earlier products. The increase in 2006 compared to 2005 was due to a full year of sales of the MicroMaxx system, which
has a higher average selling price than the Titan system, expanded international operations, and increased direct sales to hospitals. Changes in exchange rates had a 2% positive impact on revenue in 2007 and had a minimal impact on revenue in 2006.

United States

U.S. revenue increased to $104.1 million in 2007, compared to $89.7 million in 2006 and $79.8 million in 2005. The increase in 2007 compared to 2006 was attributable to increased sales in both hospital and office channels. The increase in
2006 compared to 2005 was primarily attributable to increased direct sales to hospitals, offset by a decrease in U.S. government sales due to a large order in the first quarter of 2005 and a decrease during the integration of our sales channel
partner addressing the physician office market.

International

Revenue from Europe, Africa and the Middle East increased to $59.0 million in 2007, compared to $48.9 million in 2006 and $41.2 million in 2005. The
increase in 2007 compared to 2006 was primarily due to an increase in revenue from direct sales in the UK, France and Spain offset by decreases in direct sales to Italy,



35

##### Table of Contents

which became a direct sales subsidiary in September 2007, and in Germany. The increase in 2006 compared to 2005 was primarily due to increased sales in our
direct subsidiaries in Europe, offset by decreased sales to our distributor in Italy.

Revenue from Latin America and Canada increased to
$17.8 million in 2007 compared to $12.3 million in 2006 and $9.6 million in 2005. The increase in 2007 compared to 2006 was due to a significant increase in Canada due to the sales force expansion and expansion of the dealer network in Latin
America. The increase in 2006 compared to 2005 was due to increased direct sales in Canada and increased sales to our distributors in Latin America.

Revenue from Asia Pacific increased to $24.2 million in 2007 compared to $20.2 million in 2006 and $16.9 million in 2005. The increase in 2007 compared to 2006 was due the expansion of the sales force. The increase in
2006 compared to 2005 was primarily due to distribution sales through our new distributor, Fukuda Denshi in Japan.

We anticipate that
revenue will increase in 2008 compared to 2007 due to the continued expansion of our selling efforts worldwide. We expect growth from the introduction of new products and features, from the U.S. physicians office market as we continue to
develop this channel, from the continued expansion of international operations such as India and Italy, and the overall expansion of market awareness and acceptance of our products. The expansion of new sales operations, as well as the integration
of the U.S. physician office market sales force, after the termination of our relationship with MarketBridge in January 2008, may not be as successful as anticipated and we may encounter regulatory and other issues in selling our products. Our
revenue may also be impacted by fluctuations in foreign exchange rates in the countries in which we sell our products in currencies other than the USD. Increased competition may also impact our anticipated growth in revenue. We currently face
competition from larger companies that manufacture cart-based and portable ultrasound systems and have greater financial and other resources.

Gross
margin

Gross margin decreased to 70% in 2007 compared to 71% in 2006 and 70% in 2005. The decrease in 2007 compared to 2006 was
impacted negatively from the increased sales to our distributor network and transitioning of sales from MicroMaxx to the new products, offset by the reduction in royalties to ATL, which expired in September 2007 and the positive impact of foreign
exchange rates. The increase in 2006 compared to 2005 was a result of increased sales of MicroMaxx systems which generate a higher margin than our earlier generation products.

We expect our gross margin percentage in 2008 to remain consistent with 2007. Nevertheless, increased competition from existing and new competitors could
result in lower average realized prices and could lower our gross margin. Our gross margin can be expected to fluctuate in future periods based on the mix of business between direct, government and distributor sales; mix of U.S. and international
sales; and our product and accessories sales mixes. Changes in our cost of inventory also may impact our gross margin. Adjustments to reduce carrying costs are recorded for obsolete material, earlier generation products and used or refurbished
products held either as saleable inventory or as demonstration product. If market conditions change or the introduction of new products by us impacts the market for our previously released products, we may be required to further write down the
carrying value of our inventory, resulting in a negative impact on gross margins. We rely on our sales forecasts by product to determine production volume. To the extent our sales forecasts or product mix estimates are inaccurate, we may produce
excess inventory or experience inventory shortages, which may result in an increase in our costs of revenue, a decrease in our gross margin or lost sales. Our gross margin may also be impacted by fluctuations in foreign exchange rates in the
countries in which we sell our products in currencies other than the USD.

Operating expenses

Research and development expenses increased to $25.9 million in 2007 compared to $20.2 million in 2006 and $15.2 million in 2005. The increase in 2007 compared to 2006 was due to increased headcount for development of
the M-Turbo system and S Series ultrasound tools, which were released in 2007, and for future new products and features. The increase in 2006 compared to 2005 was primarily due to increased stock-based compensation and increased headcount to support
further development of our ASIC technology and the MicroMaxx system.

We anticipate that research and development expenses will increase in
2008 compared to 2007 due to continued development of new products and features, as well as further development related to the M-Turbo system and S Series ultrasound tools. However, should our competitors develop products with features that equal or
exceed the features that exist in our products, we may incur higher than anticipated research and development costs in order to accelerate existing programs and compete more effectively.

Sales and marketing expenses increased to $91.1 million in 2007 compared to $81.6 million in 2006 and $68.1 million in 2005. The increase in 2007
compared to 2006 was attributable to the expansion of international sales operations, continued growth in the office by our sales channel partner, and increased efforts in education and training. The increase in 2006 compared to 2005 was
attributable to increased stock-based compensation, expansion of our sales channel partner into the physicians office market and our international sales operations, increased education and training efforts and commissions related to the
increase in revenue.

We anticipate that sales and marketing expenses will increase modestly in 2008 compared to 2007 due to increased
compensation for commissions related to the anticipated increase in revenues and expansion of operations in India and Italy.

General and
administrative expenses increased to $21.2 million in 2007 compared to $15.8 million in 2006 and $13.7 million in 2005. The increase in 2007 compared to 2006 was primarily due to increased legal costs related to our patent litigation. The increase
in 2006 compared to 2005 was attributable to increased stock-based compensation and increased headcount to support business growth, offset by a reduction in legal expenses.

We anticipate that general and administrative expenses will remain consistent in 2008 compared to 2007. However, we may incur increased legal expenses
regarding our ongoing litigation or unanticipated legal expenses if we become involved in any new litigation.

Total other income was $6.6 million in 2007, compared to $4.0 million in 2006 and $1.0 million in 2005. The increase in 2007 compared to 2006 was due to
increased interest income, resulting from higher cash and investment balances, and higher foreign currency gains, offset by interest expense from our convertible senior notes. The increase in 2006 compared to 2005 was primarily due to an increase in
interest income, which was attributable to our increased cash and investment balances.

Income tax expense

Income tax expense was $4.1 million in 2007, $0.6 million in 2006, and $2.4 million in 2005. Due to our profitable operations in 2007, 2006 and 2005, we
recorded income tax expense for financial reporting purposes and accordingly reflected changes in our deferred tax assets. During the fourth quarter of 2006, we reversed the valuation allowance on deferred tax assets primarily representing net
operating losses from our international operations, resulting in a reduction of $1.9 million to our income tax provision. We did not reverse the valuation allowance until it was more likely than not that the tax asset would be realized.
The income tax expense is based on a blended federal and state rate applied to U.S. income and the applicable foreign rates applied to

foreign income. While this tax expense reduced net income, no cash will be paid for income taxes, other than required alternative minimum tax and foreign and
state tax payments, until the NOL and tax credits have been fully utilized. Foreign NOLs will be utilized in jurisdictions where they are available and cash will be paid in jurisdictions that do not have foreign NOLs.

We assess our ability to realize our NOL and tax credit carryforwards in future periods and record any resulting adjustments that may be required to
deferred income tax expense. In addition, we reduce the deferred income tax asset for the benefits of NOL carryforwards utilized currently as well as the reversing effect of temporary differences. The future impact on net income may therefore be
positive or negative, depending on the net result of such adjustments and charges.

Liquidity and Capital Resources

Our cash and cash equivalents balance was $188.7 million as of December 31, 2007, compared to $45.7 million as of December 31, 2006. Cash and
cash equivalents are primarily invested in money market accounts. Our short-term and long-term investment securities totaled $121.1 million as of December 31, 2007, compared to $41.4 million as of December 31, 2006. Investment securities
generally consist of high-grade U.S. government or corporate debt and high-grade asset-backed securities. We have the ability to hold our securities until maturity, however, we classify all securities as available-for-sale, as the sale of such
securities may be required prior to maturity to implement management strategies.

As of December 31, 2007, we had $12.6 million in
Columbia Strategic Cash Portfolio, which is in the process of liquidation. In our judgment this investment, which is classified as a money market account, has a decline in fair value that is other than temporary, accordingly we have recognized an
impairment loss of $0.2 million. Distributions from this portfolio are solely at the discretion of the portfolio manager. We anticipate that $11.3 million will be distributed from this portfolio during 2008, which is recorded as a short-term
investment, and $1.3 million will be distributed after 2008, which is recorded as a long-term investment.

Operating activities provided
cash of $16.2 million in 2007, compared to cash provided of $10.8 million in 2006 and cash used of $1.1 million in 2005. The comparison of cash provided in 2007 compared to 2006 was primarily due to increases in accrued expenses and deferred income
tax provision, offset by increases in accounts receivable and inventories. The cash provided in 2006 compared to the cash used in 2005 was primarily due to increased net income before non-cash stock-based compensation in our consolidated statements
of operations and increases in accounts payable and accrued expenses, reduced by increases in accounts receivable and inventories.

We
anticipate that cash provided by operations will increase in 2008 compared to 2007 primarily due to anticipated continued profitable operations. Our ability to provide cash from operations will depend on our ability to successfully sell our
products, collect our receivables, control our inventories and manage our expenses.

Investing activities used cash of $86.1 million in
2007, compared to $3.1 million in 2006 and $0.7 million in 2005. The increase in cash used in 2007 compared to 2006 was due to the net purchases of investment securities of $78.6 million and our acquisition of LumenVu of $3.5 million. The increase
in cash used in 2006 compared to 2005 was due to an increase in purchases of property and equipment. We anticipate using cash to invest in high quality investment instruments in 2008, the extent of which will depend on the interest rate environment
during the period and the timing of cash flows from our operations during the period.

Financing activities provided cash of $214.6 million
in 2007, $12.2 million in 2006 and $9.9 million in 2005. Cash provided by financing activities was primarily due to the net proceeds from the issuance of convertible debt of $217.6 million and the exercise of stock options and employee stock
purchase plan totaling $5.6 million, offset by the net purchase of the call option intended to partially hedge our convertible note for $28.6 million and issuance of warrants for $19.5 million in 2007. This compared to proceeds from the exercise of
stock options and our employee stock purchase plan totaling $10.2 million in 2006 and $9.9 million in 2005.

We believe that our existing cash and cash generated from operations will be sufficient to fund our
operations and planned capital expenditures in 2008. Nevertheless, we may experience an increased need for additional cash in order to complete future acquisitions.

Off-balance sheet arrangements

During the year ended and as of December 31, 2007, we had no
off-balance sheet arrangements, other than obligations under our operating leases reflected in the contractual obligations table below. We are not a party to any derivative transactions except for certain foreign exchange rate hedging transactions
that we enter into from time to time, discussed more fully under Foreign currency risk in Item 7A below and the call option and warrant instruments indexed to our common stock.

We provide (i) indemnifications of varying scope and size to our customers and distributors against claims of intellectual property infringement
made by third parties arising from the use of our products; (ii) indemnifications of varying scope and size to our customers against third party claims arising as a result of defects in our products; (iii) indemnifications of varying scope
and size to consultants against third party claims arising from the services they provide to us; and (iv) guarantees to support obligations of some of our subsidiaries such as lease payments. These indemnifications and guarantees require only
disclosure. To date, we have not incurred material costs as a result of these obligations and do not expect to incur material costs in the future. Accordingly, we have not accrued any liabilities in our consolidated financial statements related to
these indemnifications or guarantees.

Contractual obligations

We have the following contractual obligations as of December 31, 2007:



|                 |  |                        |        |                  |   |           |  |           |       |                   |   |       |  |   |

In addition to the amounts shown in the table above, $3.4 million of unrecognized tax benefits
have been reflected as either liabilities or as a reduction of deferred tax assets in accordance with Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes, and we are uncertain as to
if or when such amounts may be settled.

Other commitments

In 2005, we entered into an agreement to contribute up to $1.0 million to a research university. This pledge, which is to be paid over a four-year period, is conditioned upon our election to make a payment on an
annual basis. We contributed $0.3 million in 2007, $0.3 million in 2006 and $0.1 million in 2005.

As part of our agreements with our
suppliers, suppliers may procure resources and material expected to be used for the manufacture of our product in accordance with our production schedule provided to them. We may be responsible for compensating our suppliers for these procurements
in the event these items are not used in the quantities submitted as part of the production schedule or material becomes obsolete as a result of production timing, material changes or design changes.

At December 31, 2007 we maintained a deposit of $1.0 million with our bank in the United Kingdom as security for payment of customs and duties
charges. This amount is included in other long-term assets.

In the U.S., we have complemented our direct sales efforts by entering into group purchasing agreements
with major healthcare group purchasing organizations (GPO). Typically, a GPO negotiates with medical suppliers, such as us, on behalf of the GPOs member healthcare facilities, providing such members with uniform pricing and terms
and conditions. In exchange, the GPO identifies us as a preferred supplier for its members. Member facilities participating in the GPOs purchasing program can consist of hospitals, medical group practices, nursing homes, surgery centers,
managed care organizations, long term care facilities, clinics and integrated delivery networks. Currently, we have GPO supply agreements with various groups including AmeriNet, Inc., Premier, Inc., Novation LLC, MedAssets HSCA, Inc., Broadlane,
Inc. (includes Kaiser Permanente, Tenet Healthcare and others), Consorta, Inc. and ROI/Sisters of Mercy and First Choice. These agreements require us to pay fees based on the amount of sales generated from these agreements. We recorded fees related
to these agreements as sales and marketing expenses in the amounts of $1.8 million in 2007, $1.4 million in 2006 and $1.0 million in 2005.

Recent
Accounting Pronouncements

In September 2006, the Financial Accounting Standards Board, (FASB) issued Statement of Financial
Accounting Standards (SFAS) No. 157, Fair Value Measures (SFAS 157), which defines fair value, establishes a framework for measuring fair value and enhances disclosures about fair value measures required
under other accounting pronouncements, but does not change existing guidance as to whether or not an instrument is carried at fair value. SFAS 157 is effective for fiscal years beginning after November 15, 2007. We do not believe the adoption
of SFAS 157 will have a significant impact on our future consolidated financial statements.

In February 2007, the FASB issued SFAS
No. 159, The Fair Value Option for Financial Assets and Financial Liabilities (SFAS 159), including an amendment to FASB Statement No. 115. Under SFAS 159, entities may elect to measure specified financial
instruments and warranty and insurance contracts at fair value on a contract-by-contract basis, with changes in fair value recognized in earnings each reporting period. The election, called the fair value option, will enable entities to achieve an
offset accounting effect for changes in fair value of certain related assets and liabilities without having to apply complex hedge accounting provisions. SFAS 159 is expected to expand the use of fair value measurement consistent with the
Boards long-term objectives for financial instruments. SFAS 159 is effective as of the beginning of a companys first fiscal year that begins after November 15, 2007. We do not believe the adoption of SFAS 159 will have a significant
impact on our future consolidated financial statements.

In December 2007, the FASB issued SFAS No. 141(R), Business
Combinations, (SFAS 141(R)) and SFAS No. 160, Non-controlling Interest in Consolidated Financial Statements, an amendment of ARB No. 51, (SFAS 160). These new standards will significantly change
the accounting for and reporting of business combination transactions and non-controlling (minority) interests in consolidated financial statements. SFAS 141(R) and SFAS 160 are required to be adopted simultaneously and are effective as of the
beginning of a companys first fiscal year that begins after December 15, 2008. We are currently reviewing the provisions of SFAS 141 (R) and SFAS 160 to determine the impact on our future consolidated financial statements.



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

Interest rate risk

We are exposed to market risk relating to changes in interest rates, which could adversely affect the
value of our investments in marketable securities.

As of December 31, 2007, our investments consisted of $119.9 million of
interest-bearing debt securities with maturities or expected maturities of less than one year and $1.3 million of interest-bearing debt securities



40



---

##### Table of Contents

with expected maturities of more than one year. Generally we have the ability to hold these securities until maturity, however, we have classified them as
available-for-sale in the event of unanticipated cash needs. The interest bearing securities are subject to interest rate risk and will fall in value if market interest rates increase. We believe that the impact on the fair market value of our
securities and related earnings for 2008 from a hypothetical 10% increase or decrease in market interest rates would not have a material impact on the investment portfolio.

Foreign currency risk

Except for sales transacted by our wholly-owned foreign subsidiaries, we
transact all our sales in USDs; therefore, the obligations of many of our international customers are in USDs. Our exposure to risk from fluctuations in foreign currencies relates primarily to the strengthening of the USD against the local currency
of our international subsidiaries, which may result in foreign exchange losses on transactions with them, and our international customers, which may impact our ability to collect amounts owed by them.

As of December 31, 2007 60% of our outstanding accounts receivable balance was from international customers, of which 58%, or $21.4 million, was
denominated in a currency other than USDs. Total sales for the year ended December 31, 2007 denominated in a currency other than USDs were $62.8 million, or 31% of total consolidated revenues. The British pound, the European Union euro and the
Japanese yen represented the majority of financial transactions executed in a currency not denominated in USDs. We regularly review our receivable positions in foreign countries for any indication that collection may be at risk. In addition, we
utilize letters of credit where they are considered necessary in order to mitigate our collection risk.

We periodically enter into foreign
currency forward and participating forward contracts to reduce the impact of adverse fluctuations on earnings associated with foreign currency exchange rate changes. As of December 31, 2007, we had $40.0 million in notional amount of foreign
currency contracts that expire on March 31, 2008. They serve as hedges of a substantial portion of our intercompany balances denominated in a currency other than the USD. These foreign currencies primarily include the British pound, the Euro
and the Japanese yen. A sensitivity analysis of a change in the fair value of these contracts indicates that if the USD weakened by 10% against the applicable foreign currency, the fair value of these contracts would decrease by $2.4 million.
Conversely, if the USD strengthened by 10% against the applicable foreign currency, the fair value of these contracts would increase by $4.0 million. Gains and losses in the fair value of these contracts are intended to offset the losses and a
portion of the gains on the underlying intercompany balances. These offsetting gains and losses are not reflected in the sensitivity analysis above. The fair value of these contracts as of December 31, 2007 was not material to our results of
operations or our financial position.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders

SonoSite, Inc.:

We have audited the accompanying
consolidated balance sheets of SonoSite, Inc. and subsidiaries as of December 31, 2007 and 2006, and the related consolidated statements of operations, cash flows, and shareholders equity and comprehensive income for each of the years in
the three-year period ended December 31, 2007. In connection with our audits of the consolidated financial statements, we also have audited the financial statement schedule listed in Item 15(a). These consolidated financial statements and
the financial statement schedule are the responsibility of the Companys management. Our responsibility is to express an opinion on these consolidated financial statements and the financial statement schedule based on our audits.

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

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the
financial position of SonoSite, Inc. and subsidiaries as of December 31, 2007 and 2006, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2007, in conformity with
U.S. generally accepted accounting principles. Also in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the
information set forth therein.

As discussed in Note 2 in the consolidated financial statements, the Company adopted Statement of Financial
Accounting Standards No. 123 (revised 2004), Share-Based Payment, effective January 1, 2006.

We also have audited, in accordance
with the standards of the Public Company Accounting Oversight Board (United States), SonoSite Inc.s internal control over financial reporting as of December 31, 2007, based on criteria established in Internal ControlIntegrated
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated March 14, 2008 expressed an unqualified opinion on the effectiveness of the Companys internal control over financial
reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders

SonoSite, Inc.:

We have audited SonoSite Inc.s internal control over financial reporting as of December 31, 2007, based on criteria established in Internal
Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company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 (Item 9A(b)). 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, and testing and evaluating the design and operating effectiveness of internal control based on
the assessed risk. Our audit also included 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, SonoSite, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2007,
based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of SonoSite, Inc. as of December 31, 2007 and 2006, and the
related consolidated statements of operations, cash flows, and shareholders equity and comprehensive income for each of the years in the three-year period ended December 31, 2007, and our report dated March 14, 2008 expressed an
unqualified opinion on those consolidated financial statements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Business Overview

SonoSite develops, manufactures, and distributes hand-carried ultrasound systems for use across medical specialties and in a range of treatment settings.

We commenced operations as a division of ATL Ultrasound, Inc. (ATL). On April 6, 1998, we became an independent, publicly
owned company through a distribution of one new share of our stock for every three shares of ATL stock held as of that date. ATL retained no ownership in SonoSite following the spin-off.

2. Summary of Significant Accounting Policies

Basis of presentation and use of estimates

The consolidated financial statements are prepared in conformity with U.S. generally accepted accounting principles. The
consolidated financial statements include the accounts of SonoSite, Inc., and our wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. In preparing the financial statements,
management must make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

Reclassification of prior period balances

Certain amounts reported in previous periods have been reclassified to conform to current period presentation.

Cash and cash equivalents

Cash and cash equivalents primarily consist of money market accounts with major U.S. banks and highly liquid debt instruments with maturities at purchase of three months or less.

Investment securities

Investment securities primarily consist of high-grade U.S. government or corporate debt and high-grade asset-backed securities. We have the ability to hold our securities until maturity; however, we classify all securities as
available-for-sale, as the sale of such securities may be required prior to maturity to implement management strategies. These securities are carried at fair value, with the unrealized gains and losses reported as a component of other comprehensive
income (loss) until realized. Realized gains and losses from the sale of available-for-sale securities, if any, are determined on a specific identification basis.

A decline in market value of any available-for-sale security below cost that is determined to be other than temporary results in a revaluation of its carrying amount to fair value. The impairment is charged to
earnings and a new cost basis for the security is established. Premiums and discounts are amortized or accreted over the life of the related security as an adjustment to yield using the effective interest method. Interest income is recognized when
earned. We may incur unrealized losses due to changes in market value attributable to changes in interest rates. We have the ability and intent to hold our investments until a recovery of cost, which may be maturity.

Accounts receivable

In the
ordinary course of business, we grant credit to a broad customer base. Of the accounts receivable balance at December 31, 2007, 60% and 40% were receivable from international and domestic customers, prior

to any allowance for doubtful accounts. The same percentages as of December 31, 2006 were 56% and 44% prior to any allowance for doubtful accounts.

We maintain allowances for estimated losses resulting from the inability of our customers to make required payments. When we determine
that amounts owed from customers are uncollectible, such amounts are charged off against the allowances for doubtful accounts. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make
payments, additional allowances may be required.

Fair value of financial instruments

The carrying value of our financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and certain long-term other
assets, approximates fair value. Cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to their short-term nature. These financial instruments included in other long-term assets approximate fair value as
interest rates on these items approximate market. Our investment securities, which primarily consist of high-grade debt securities, are carried at fair value.

We utilize foreign currency forward and participating forward contracts to reduce our exposure to foreign currency risk due to fluctuations in exchange rates underlying the value of intercompany accounts receivable
denominated in foreign currencies. These contracts did not qualify for hedge accounting and accordingly are marked-to-market with changes in fair value recorded in income.

Inventories

Inventories are
stated at the lower of cost or market, on a first-in, first-out method. Included in our inventories balance are demonstration products used by our sales representatives and marketing department. Adjustments to reduce carrying costs are recorded for
obsolete material, shrinkage, earlier generation products and used or refurbished products held either as saleable inventory or as demonstration product. If market conditions change or if the introduction of new products by us impacts the market for
our previously released products, we may be required to further write down the carrying cost of our inventories.

Property and
equipment

Property and equipment are stated at historical cost, less accumulated depreciation and amortization. Maintenance and
repair costs are expensed as incurred, and additions and improvements to property and equipment are capitalized.

Depreciation and
amortization are calculated using the straight-line method over estimated useful lives as follows:



|                        |  |                                                        
|----------------------- |  | -------------------------------------------------------
|Asset                   |  | Estimated Useful Lives                                 
|Equipment and computers |  | 35 years                                              
|Software                |  | 3 years                                                
|Furniture and fixtures  |  | 5 years                                                
|Leasehold improvements  |  | Lesser of estimated useful life or remaining lease term

2. Summary of Significant Accounting Policies(Continued)



The carrying value of long-lived asset groups is evaluated for impairment when events or changes in
circumstances occur that may indicate the carrying amount of the asset group may not be recoverable. For depreciable property and equipment and amortizable intangible assets, we evaluate the carrying value of the asset group by comparing the
estimated future undiscounted cash flows generated from the use of the asset group and its eventual disposition with the asset groups net book value. If the estimated future undiscounted cash flows from an asset group are less than the net
book value of the asset group, we record an impairment loss equal to the excess of the net book value over the estimated fair market value of the asset group.



Goodwill and other intangible assets

We perform goodwill impairment tests annually in the fourth quarter of each year, and more frequently if facts and circumstances indicate reporting unit carrying values exceed estimated reporting unit fair values. Intangibles subject to
amortization, which consist mainly of acquired technology and non-compete agreements, are amortized using the straight-line method over their estimated useful lives of three to seven years. Indefinite-lived intangible assets are tested for
impairment annually, and more frequently if facts and circumstances indicate that the asset might be impaired.

Concentration of
credit and supply risk

Financial instruments that potentially subject us to concentrations of credit risk consist principally of
cash equivalents, investment securities and accounts receivable.

We depend on some single-source suppliers to provide highly specialized
parts and other components, and may experience an interruption of supply if a supplier is unable or unwilling to meet our time, quantity and quality requirements. There are relatively few alternative sources of supply for some of these items. A
change in demand for some parts by other companies in our industry could also interrupt our supply of components.

Our circuit boards are
produced by one of the worlds largest electronic manufacturing services suppliers who produce the boards in their Thailand manufacturing facility. If we experience delays in the receipt or a deterioration in product yields of these components,
we may experience delays in manufacturing or an increase in costs resulting in lost sales or a deterioration in gross margin.

Revenue recognition

We recognize revenue on products and accessories when goods are shipped under an agreement with
a customer, risk of loss and title have passed to the customer, sales returns are estimable and collection of any resulting receivable is reasonably assured. For service contracts, revenue is recognized as services are provided or over the term of
the contract. Revenue is recorded net of estimated returns. We estimate returns by reviewing our historical returns, considering customer reaction to new product introductions and current economic conditions. Sales discounts are recorded as a
reduction in revenue. We make product upgrades available for purchase to our customers.

Sales to distributors are generally made pursuant
to standard distributor agreements. We recognize revenue when risk of loss and title have transferred to the distributor and collection of any resulting receivable is reasonably assured. Our only significant post-shipment obligation to distributors
is our product warranty covering materials and workmanship. The distributor can only reject products for an obvious defect or shipping

error, generally within 30 days of receipt, and in such cases, replacement products would be sent. Since the distributors remedy is the replacement of
the product and not a refund or credit, we do not defer revenue associated with these sales. Costs associated with the repair of returned, defective products are captured in our warranty accrual. Our standard distributor arrangements do not have any
other return provisions.

Our sales arrangements may contain multiple elements, which include hardware and software products. Revenue from
the sale of software, software-related elements, and hardware when the software elements are more than incidental to the product as a whole, is recognized in accordance with software revenue recognition rules. We have vendor specific objective
evidence (VSOE) of fair value for our products. Accordingly, for transactions that have undelivered elements for which we have VSOE of the elements, revenue equal to the total fair value of the undelivered elements is deferred and is not
recognized until the element is delivered to the customer. When the undelivered element represents services under extended service contracts, revenue equal to the stated price is deferred and recognized evenly over the contract term as those
services are provided.

Warranty expense

We accrue estimated warranty expense at the time of sale for costs expected to be incurred under our product warranties. This provision for warranty expense is made based upon our historical product failure rates and
service repair costs using managements judgment. Our warranty period is five years for the MicroMaxx system, M-Turbo system and S Series ultrasound tools, with certain exceptions. Our warranty period for our other products is one year. The
warranty is included with the original purchase. In addition to a standard warranty, we offer extended warranty and service agreements for coverage beyond the standard warranty period or coverage above what is covered by a standard warranty.

Research and development

Research and development costs are expensed as incurred with the exception of equipment acquired for research and development activities that has alternative future uses. We have determined that technological
feasibility for our software-related products is reached shortly before the products are released to manufacturing. Costs incurred after technological feasibility is established are not material, and accordingly, we expense all software-related
research and development costs when incurred.

Advertising costs

We expense costs for advertising and promotional activities as incurred. Advertising and promotional expenses for the years ended December 31, 2007,
2006 and 2005 were $10.2 million, $11.7 million, and $11.2 million.

Income taxes

Deferred income taxes are provided based on the estimated future tax effects of temporary differences between financial statement carrying amounts of
existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards arising since our inception.

Deferred tax assets and liabilities are measured using enacted tax rates that are expected to apply to taxable income in the years in which those temporary differences and carryforwards are expected to be recovered or

settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A
valuation allowance is established when necessary to reduce deferred tax assets to the amount, if any, expected to be realized.

Stock-based compensation

On January 1, 2006, we adopted SFAS No. 123R, Share-Based Payment
(SFAS 123R), using the modified prospective transition method. SFAS 123R requires entities to recognize compensation expense for awards of equity instruments to employees based on the grant-date fair value of those awards (with limited
exceptions). The benefits of tax deductions in excess of recognized compensation expense are reported as cash provided by financing activities, rather than as an operating cash flow, and therefore reduces cash provided by operating activities and
increases cash provided by financing activities. This amount is shown as Excess tax benefit from exercise of stock options on our consolidated statement of cash flows. Total cash flows remain unchanged from what has been previously
reported. We have adopted the long-haul method to calculate the historical pool of windfall tax benefits, under which we calculate on a grant by grant basis the windfall or excess tax benefit that arose upon exercise of each award based
on a comparison of the total tax deduction to the as-if deferred tax asset that would have been recorded had we followed the recognition provisions of SFAS No. 123, Accounting for Stock-Based Compensation since its
effective date. We use a tax law ordering methodology for determining when tax benefits from stock option exercises are realized.

Prior to
adoption of SFAS 123R we accounted for stock option and restricted stock unit (RSU) grants under the intrinsic value method in accordance with the provisions of Accounting Principles Bulletin (APB) Opinion No. 25,
Accounting for Stock Issued to Employees. Accordingly, compensation cost related to stock option grants to employees had been recognized only to the extent that the fair market value of the stock exceeded the exercise price of the stock
option at the date of the grant. We recognized compensation expense for the fair value of RSU grants ratably over the applicable vesting period. The fair value was based on the market price of our stock on the date of grant. We recorded share-based
compensation related to stock options in accordance with the accelerated methodology described in Financial Accounting Standards Board Interpretation No. 28, Accounting for Stock Appreciation Rights and Other Variable Stock Option or
Award Plans. We presented all tax benefits resulting from the exercise of stock options as operating cash inflows in our consolidated statement of cash flows.

Net income per share

Basic net income per share is based on the weighted average number of
common shares outstanding during the period. Diluted net income per share is based on the weighted average number of common and dilutive common equivalent shares outstanding during the period. Potentially dilutive common equivalent shares consist of
common stock issuable upon exercise of stock options, restricted stock, and warrants using the treasury stock method. Diluted net income per share would also be impacted to reflect shares issuable upon conversion of our convertible senior notes if
our share price exceeds $38.20 per share. The call option we purchased is anti-dilutive and, therefore, excluded from the calculation of diluted net income per share.

|--- | ---------------------------------------------------------------------------------------------------------------------------------------

|(2) | As further detailed in note 9, Convertible senior notes, in July 2007 we issued warrants to purchase up to 2.5 million shares of our common stock with a strike price of $46.965,
which are anti-dilutive since the strike price of the warrants is greater than the market price of our common stock.

The
computation of diluted net income per share does not include any potential dilutive common shares associated with our convertible senior notes. The convertible senior notes would become dilutive and included in the calculation of diluted net income
per share, for the number of shares that would be required to satisfy the conversion spread, if the average market price of our common stock exceeds approximately $38.20 per share.

Accumulated other comprehensive income

Unrealized gains or losses on our available-for-sale securities and foreign currency translation adjustments are included in accumulated other comprehensive income.

Foreign currency translation

The functional currencies of our international subsidiaries, consisting primarily of the British pound, the European Union euro and the Japanese yen, are
the local currency of the country in which the subsidiary is located. Assets and liabilities denominated in foreign currencies are translated at the exchange rate on the balance sheet date. Revenues, costs and expenses and cash flows of
international operations are translated at average rates of exchange prevailing during the period.

Recent accounting pronouncements

In September 2006, the Financial Accounting Standards Board, (FASB) issued Statement of Financial Accounting Standards
(SFAS) No. 157, Fair Value Measures (SFAS 157), which defines fair value, establishes a framework for measuring fair value and enhances disclosures about fair value measures required under other accounting
pronouncements, but does not change existing guidance as to whether or not an instrument is carried at fair value. SFAS 157 is effective for fiscal years beginning after November 15, 2007. We do not believe the adoption of SFAS 157 will have a
significant impact on our future consolidated financial statements.

In February 2007, the FASB issued SFAS No. 159, The Fair
Value Option for Financial Assets and Financial Liabilities (SFAS 159), including an amendment to FASB Statement No. 115. Under SFAS 159, entities may elect to measure specified financial instruments and warranty and insurance
contracts at fair value on a contract-by-contract basis, with changes in fair value recognized in earnings each reporting period. The election, called the fair value option, will enable entities to achieve an offset accounting effect for changes in
fair value of certain related assets and liabilities without having to apply complex hedge accounting provisions. SFAS 159 is effective for fiscal years beginning after November 15, 2007. We do not believe the adoption of SFAS 159 will have a
significant impact on our future consolidated financial statements.

In December 2007, the FASB issued SFAS No. 141(R), Business
Combinations, (SFAS 141(R)) and SFAS No. 160, Non-controlling Interest in Consolidated Financial Statements, an amendment of ARB No. 51, (SFAS 160). These new standards will significantly change
the accounting for and reporting of business combination transactions and non-controlling (minority) interests in consolidated financial statements. SFAS 141(R) and SFAS 160 are required to be adopted simultaneously and are effective for fiscal
years beginning after December 15, 2008. We are currently reviewing the provisions of SFAS 141(R) and SFAS 160 to determine the impact on our future consolidated financial statements.

3. Technology Transfer and License Agreement with ATL

We license ultrasound technology from ATL under a Technology Transfer and License Agreement executed at the time of our spin-off as a public company in
1998. Under that agreement, we took ownership of certain ultrasound technology developed as part of a government grant and also patent rights, which had been established or were being pursued for that technology. As part of this agreement, we also
entered into a cross-license whereby we had the exclusive right to use certain ATL technology existing on April 6, 1998 or developed by ATL during the three-year period following April 6, 1998 in ultrasound systems weighing 15 pounds or
less, and ATL had the exclusive right to use our technology existing on April 6, 1998 or developed by us during the same three-year period in ultrasound systems weighing more than 15 pounds. On April 6, 2003, this cross-license became
nonexclusive and, except for the patented technology of each party, now extends to all ultrasound systems regardless of weight.

Our
license from ATL had a royalty equivalent to a percentage of the net sales of ultrasound products under fifteen pounds that use ATL technology, until the royalty payments expired on September 21, 2007. For the years ended December 31,
2007, 2006 and 2005, we incurred a royalty expense to ATL of $1.5 million, $2.2 million and $2.0 million, which is included in cost of revenue.

As of December 31, 2007, we had $12.6 million in Columbia Strategic Cash Portfolio, which is
in the process of liquidation. In our judgment this investment, which is classified as a money market account, has a decline in fair value that is other than temporary, accordingly we have recognized an impairment loss of $0.2 million. Distributions
from this portfolio are solely at the discretion of the portfolio manager. We anticipate that $11.3 million will be distributed from this portfolio during 2008, which is recorded as a short-term investment and $1.3 million will be distributed after
2008, which is recorded as a long-term investment.

6. Acquisitions

In July 2007, we acquired all of the outstanding stock of LumenVu, Inc. (LumenVu), a private development stage company that developed, in conjunction with a leading academic research institution, a
patented technology to improve the accuracy of catheter placement. The results of LumenVus operations have been included in our consolidated financial statements since that date. The acquisition, which was an asset purchase, had a purchase
price that consisted of cash consideration of $2.9 million, note receivable forgiveness of $0.1 million, assumed liabilities of $0.6 million, which were paid at closing, and future cash payments of $10.0 million, which had a present value of $4.0
million at the date of acquisition. The future cash payments are contingent upon the continued development of the product and revenues recognized from the sale of products incorporating this technology. The liability for contingent consideration
will be accreted to operating expenses over the expected payment period. During 2007, we recorded $0.3 million of accretion expense. Based on the fair value of assets acquired $11.8 million was allocated to an intangible technology asset, which will
be amortized over ten years commencing with sales of products incorporating this technology. No amortization expense has been recorded as of December 31, 2007. Since the amortization of this intangible technology asset is not deductible for tax
purposes we have recorded a deferred tax liability of $4.3 million. Additionally, we recorded a deferred tax asset associated with net operating losses of LumenVu of $0.2 million. We expect to introduce products based on this technology in early
2009.

In April 2005, we acquired the remaining 70% of SonoSite China Medical for $0.4 million. The results of SonoSite China Medical
operations have been included in our consolidated financial statements since that date. The estimated fair value of the assets acquired and liabilities assumed at the date of acquisition was $0.5 million primarily for indefinite-lived intangible
assets, including $0.1 million of deferred tax assets. The indefinite-lived intangible asset represents reacquired distribution rights. We have determined that they have indefinite lives because there are no legal, regulatory or contractual
provisions that may limit their useful lives.

In May 2004, we acquired 100% of the outstanding common shares of SonoMetric Health, Inc.
(SonoMetric). The results of SonoMetrics operations have been included in our consolidated financial statements since that date. We purchased all of SonoMetrics outstanding common shares for an immediate cash payment of $1.5
million, plus future cash payments of up to $4.5 million contingent upon the amount of revenue recognized from the sale of the purchased software over the five-year period following the closing date of the acquisition. We accrued contingent payments
of $1.0 million and $0.7 million as of December 31, 2007 and 2006, respectively, as a result of revenue recognized on the sale of the software. These contingent payments are recorded as additional goodwill.

7. Goodwill and other intangible assets

As of
December 31, 2007 and 2006, goodwill was $3.4 million and $2.5 million, respectively. As of December 31, 2007 intangible assets subject to amortization, which collectively had a remaining weighted average useful life of 10.4 years, were
$12.4 million, net of accumulated amortization of $1.4 million. As of December 31, 2006 intangible assets subject to amortization were $0.9 million, net of accumulated amortization of $1.1 million. Amortization expense of $0.3 million, $0.4
million and $0.4 million related to intangible assets was recorded for the years ended December 31, 2007, 2006 and 2005. Amortization expense of intangible assets is estimated to be $0.5 million in 2008, $1.4 million per year in 2009 and 2010
and $1.3 million in 2011. As of December 31, 2007 and 2006, indefinite-lived intangible assets were $0.5 million. During the fourth quarter of 2007, we completed our annual impairment assessment of our goodwill and indefinite-lived intangible
assets and determined that they were not impaired.

8. Hedging activities

During 2007 the currencies hedged were the British pound, the European Union euro, the Japanese yen, the Australian dollar and the Canadian dollar. As of December 31, 2007, we had $40.0 million in notional amount
of foreign currency forward and participating forward contracts. The fair value of these contracts as of December 31, 2007 was not material to our results of operations or financial position. These contracts expire on March 31, 2008 and
serve as economic hedges of a substantial portion of our intercompany balances denominated in a currency other than the USD. Recognized gains and losses from foreign currency contracts for the years ended December 31, 2007, 2006 and 2005 were
losses of $2.1 million, losses of $1.1 million and gains of $2.3 million, and are included in other income (loss) in the consolidated statements of operations. These gains and losses were substantially offset by foreign exchange gains and losses on
intercompany balances. Foreign exchange gains and losses on intercompany balances, net of foreign currency contracts, were gains of $1.4 million and $0.4 million for the years ended December 31, 2007 and 2006, and losses of $0.8 million the
year ended December 31, 2005.

9. Convertible senior notes

In July 2007, we completed the offering of $225.0 million aggregate principal amount of 3.75% convertible senior notes (Notes) due 2014. The Notes may be converted, under certain circumstances described
below, based on an initial conversion rate of 26.1792 shares of common stock per $1,000 principal amount of notes (which is equivalent to an initial conversion price of approximately $38.20 per share). The net proceeds from the issuance of the Notes
were $217.6 million, after deducting debt issuance costs.

Holders may convert their Notes based on an initial conversion rate of 26.1792
shares of our common stock per $1,000 principal amount of notes, subject to adjustment, at their option at any time prior to April 15, 2014 under the following circumstances: (1) during any fiscal quarter beginning after September 30,
2007 (and only during such fiscal quarter), if the last reported sale price of our common stock for at least 20 trading days during the 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter is greater
than or equal to 130% of the applicable conversion price on each applicable trading day of such preceding fiscal quarter; (2) during the five business day period after any ten consecutive trading day period in which the trading price per note
for each day of that ten consecutive trading day period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on such day; or (3) upon the occurrence of specified corporate transactions. On
or after April 15, 2014, holders may convert their Notes at any time prior to the close of business on the third scheduled trading day immediately preceding the maturity date.

Upon conversion, we will pay cash and shares of our common stock, if any, based on a daily conversion rate multiplied by a volume weighted average price
of our common stock during a specified period following the conversion date. Conversions will be settled in cash up to the principal amount of the Notes, with any conversion value above the principal amount settled in shares of our common stock.
Holders of the Notes may require us to repurchase the notes for cash equal to 100% of the principal amount to be repurchased plus accrued and unpaid interest upon the occurrence of a fundamental change. In addition, we will adjust the conversion
rate for holders who elect to convert notes in connection with a fundamental change. We may not redeem any of the Notes at our option prior to maturity.

We will pay cash interest at an annual rate of 3.75%, payable semi-annually on January 15 and July 15 of each year, beginning January 15, 2008. Debt issuance costs of approximately $7.1 million are
being amortized to interest expense over the term of the Notes and have been included in other assets in our consolidated balance sheet.

9. Convertible senior notes(Continued)



In connection with the offering, we used a portion of the offering proceeds to enter into a
convertible note hedge transaction whereby we purchased a call option for up to 2.5 million shares of our common stock at a price of $38.1982 per share. These options, which hedge approximately 42% of the risk of additional share issuance,
expire on July 15, 2014 and must be settled in net shares. The cost of the call option was $28.6 million and has been recorded as a reduction to stockholders equity. The tax benefit from the deduction related to the purchase of the call
option as part of the convertible note hedge transaction will be recorded to additional paid in capital over the term of the hedge transaction.

Additionally, to partially offset the cost of the convertible note hedge transaction, we sold
warrants to purchase up to 2.5 million shares of our common stock at a price of $46.965 per share. The warrants expire on various dates from October 15, 2014 through the 60thscheduled trading day following October 15, 2014 and must be settled in net shares. We received approximately $19.5 million in cash proceeds from the sales of these warrants
and they have been recorded as an increase to stockholders equity.

The net proceeds from the issuance of the Notes, net of issuance costs,
the convertible note hedge transaction, and the warrant transaction were $208.5 million.

The fair value of our convertible senior notes,
which have a carrying value of $225.0 million, was $249.1 million at December 31, 2007.

10. Shareholders equity

Stock compensation plans

At
December 31, 2007, we had seven stock-based employee compensation plans: the 1998 Nonofficer Employee Stock Option Plan (1998 NOE Plan), the 1998 Stock Option Plan (1998 Plan), the Nonemployee Director Stock Option Plan
(Director Plan), the Management Incentive Compensation Plan (MIC Plan), the Adjustment Plan, the 2005 Stock Incentive Plan (2005 Plan) and the 2005 Employee Stock Purchase Plan (2005 ESPP Plan).

Total stock-based compensation expense recognized in our consolidated statements of operations for the years ended December 31, 2007,
2006 and 2005 were $6.8 million, $7.3 million and $0.3 million, respectively, before income taxes. Stock-based compensation expense relates to stock options of $3.0 million, RSU awards of $3.3 million and the employee stock purchase plan of $0.5
million in 2007, stock options of $4.0 million, RSU awards of $2.7 million and the employee stock purchase plan of $0.6 million in 2006 and RSU awards of $0.4 million net of the reversal of stock options of $0.1 million in 2005. The related deferred
tax benefit was $2.3 million, $2.2 million and $0.1 million for the years ended December 31, 2007, 2006 and 2005. The amount of stock-based compensation capitalized to inventory was not material as of December 31, 2007 or 2006.

Under the 1998 NOE Plan, 1998 Plan, MIC Plan, 2005 Plan and option grants outside our stock option plans, as of December 31, 2007, 2,565,452
total shares of common stock were authorized primarily for issuance upon exercise of stock options at prices equal to the fair market value of our common shares at the date of grant. As of December 31, 2007, 312,428 shares were available for
grant under these stock option plans. In most cases, stock options issued prior to October 22, 2002 are exercisable at 25% each year over a four-year vesting period and have a ten-year term from the grant date. Employee option grants made after
October 2002 to new employees vest 25% after one year of employment and then monthly over the next three years, and grants made to employees after their first year of employment vest monthly over four years.

Under the Director Plan, as of December 31, 2004, 125,000 shares of common stock were authorized
for issuance of stock options at prices equal to the fair market value of our common shares at the date of grant. At December 31, 2005, there were no longer shares available for grant under this Plan. Stock options are exercisable and vest in
full one year following their grant date provided the optionee has continued to serve as our director. Each option expires on the earlier of ten years from the grant date or 90 days following the termination of a directors service as our
director.

The 2005 ESPP Plan, which qualifies under Section 423 of the Internal Revenue Code, permits all U.S. based employees to
purchase shares of our common stock. Participating employees may purchase common stock through payroll deductions at the end of each participation period at a purchase price equal to 85% of the lower of the fair market value of the common stock at
the beginning or the end of the participation period. As of December 31, 2007 1,000,000 shares of common stock were authorized for issuance under the 2005 ESPP Plan. During the years ended December 31, 2007, 2006 and 2005, 74,501, 76,907
and 28,251 shares of common stock were issued under this plan, respectively.

Prior to the spin-off from ATL, we had no stock option plans
specifically identified as our plans. All stock options granted through that date were part of ATL option plans.

In 2003, we granted
10,000 options to a non-employee. For the year ended December 31, 2005, we recorded stock-based compensation expense related to these options of $0.1 million. During the year ended December 31, 2006, we determined that the vesting
requirements of the 10,000 options would not be met. Accordingly, we reversed $0.1 million in previously recorded stock-based compensation expense.

Through 2004, we granted a total of 165,000 options outside of all plans to corporate officers, of which 85,000 options are outstanding. These options are included within the information presented herein and contain similar provisions to
our 1998 Plan.

The following table illustrates the effect on net income and net income per share if we had applied the fair value
recognition provisions of SFAS 123 to stock-based employee compensation (in thousands, except per share data):

The fair value for stock option awards was estimated at the date of grant using the Black-Scholes
option pricing model with the following weighted average assumptions for the years ended December 31, 2007, 2006 and 2005:

The expected term of the options represents the estimated period of time until exercise and is
based on historical experience of similar awards, giving consideration to the contractual terms, vesting schedules and expectations of future employee behavior. Expected stock price volatility is based on historical volatility of our stock over the
historical period commensurate with the expected term assumptions. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant with an equivalent remaining term. The Company has not paid dividends in the past
and does not plan to pay any dividends in the near future.

The assumptions used to calculate the fair value of options granted are
evaluated and revised, as necessary, to reflect market conditions and our experience. In conjunction with the adoption of SFAS 123R, we changed our method of attributing the value of stock-based compensation expense from the accelerated
multiple-option method to the straight-line single-option method. Compensation expense for all stock-based awards granted on or prior to December 31, 2006 will continue to be recognized using the accelerated multiple-option method, while
compensation expense for all stock-based awards granted subsequent to December 31, 2006 will be recognized using the straight-line single-option method. Compensation expense is recognized only for those options expected to vest, with
forfeitures estimated at the date of grant based on the Companys historical experience and future expectations. Prior to the adoption of SFAS 123R, the effect of forfeitures on the pro forma expense amounts was recognized as the forfeitures
occurred.

The aggregate intrinsic value in the table above is based on our average stock price of $33.41 on
December 31, 2007, which would have been received by the optionees, excluding applicable income taxes, had all options been exercised on that date. As of December 31, 2007, total unrecognized stock-based compensation expense related to
nonvested stock options was $2.3 million, which is expected to be recognized over a weighted average period of approximately 1.3 years. During the years ended December 31, 2007, 2006 and 2005, the total intrinsic value of stock options
exercised was $3.6 million, $11.1 million and $10.5 million, respectively.

The Company issues new shares of common stock upon exercise of
stock options.

Restricted stock units

We have granted RSU awards to employees under the 1998 Plan and the 2005 Plan. Generally, the vesting period for our RSU awards is three years from the
date of grant. As of December 31, 2007, total unrecognized stock-based compensation expense related to nonvested RSU awards was $6.2 million, which is expected to be recognized over a weighted average period of approximately 1.5 years.

Stock purchase rights

In April 1998, we and First Chicago Trust Company of New York (First Chicago) entered into a Rights Agreement. The Rights Agreement was
subsequently amended in October 2001 to reflect that EquiServe Trust Company, N.A. had succeeded First Chicago as the rights agent, and in August 2003, and again in November 2007, to reflect that Computershare Trust Company N.A. had succeeded
EquiServe and to adopt certain changes approved by our Board of Directors. The Rights Agreement has certain anti-takeover provisions, which will cause substantial dilution to a person or group that attempts to acquire us. Under the Rights Agreement,
each of our shareholders has one share purchase right for each share of common stock held, with each right having an exercise price approximating our board of directors estimate of the long-term value of one share of our common stock. The
rights are triggered if an acquiror acquires, or successfully makes a tender offer for, 20% or more of our outstanding common stock. In such event, each shareholder other than the acquiror would have the right to purchase, at the exercise price, a
number of newly issued shares of our capital stock at a 50% discount. If the acquiror were to acquire 50% or more of our assets or earning power, each shareholder would have the right to purchase, at the exercise price, a number of shares of
acquirors stock at a 50% discount. Our board of directors may redeem the rights at a nominal cost at any time before a person acquires 20% or more of our outstanding common stock, which allows board-approved transactions to proceed. In
addition, our board of directors may exchange all or part of the rights (other than rights held by the acquiror) for such number of shares of our common stock equal in value to the exercise price. Such an exchange produces the desired dilution
without actually requiring our shareholders to purchase shares. The Rights Agreement expires on April 5, 2013.

11. Income taxes(Continued)



The provision for income taxes differs from the amount computed by applying the federal statutory
income tax rate to the net income or loss. The sources and tax effects of the differences for the years ended December 31 are as follows:

The tax effects of temporary differences and carryforwards that give rise to significant portions
of deferred tax assets and deferred tax liabilities at December 31 are as follows (in thousands):

The valuation allowance on deferred taxes decreased by $4.0 million and $1.0 million in 2006 and
2005, respectively. The allowance was zero as of December 31, 2007 and 2006. The valuation allowance on foreign deferred tax assets was eliminated in 2006 because consideration of all relevant factors, including current operations and recent
earnings history indicate that realization of the related deferred tax assets are now more likely than not to occur.

For income tax
purposes, our results through the spin-off from ATL were included in the consolidated federal income tax return of ATL and, accordingly, the net operating loss (NOL) generated prior to the spin-off from ATL is not available to us for use
in periods subsequent to that date. During the period from the spin-off from ATL through December 31, 2007, we accumulated U.S. federal income tax NOL carryforwards, net of amounts utilized, of $29.3 million that expire between 2020 and 2026
and foreign NOL carryforwards, net of

amounts utilized, of $8.7 million, of which $8.6 million are perpetual in nature and $0.1 million expire in 2014. Additionally, we accumulated research and
experimentation tax credit carryforwards of $2.9 million that expire between 2018 and 2027 and alternative minimum tax credits of $0.9 million that are perpetual in nature.

We have not provided for U.S. deferred taxes on earnings of non-U.S. subsidiaries as such earnings, which are immaterial, are deemed permanently
reinvested. Determination of unrecorded deferred taxes on earnings of non-U.S. subsidiaries is not practicable.

Under certain provisions
of the Internal Revenue Code of 1986, as amended, the availability and utilization of our NOL and tax credit carryforwards may be subject to limitation if it should be determined that there has been a change in ownership of more than 50%.

On January 1, 2007, we adopted FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes (FIN
48). The adoption of FIN 48 did not have a material effect on our consolidated financial position or results of operations. Our unrecognized tax benefits at December 31, 2007 related to various foreign jurisdictions and U.S. tax credits.
A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):



|                                                  |  |   |       |

|Balance at December 31, 2007                      |  | $ | 3,418 |  
|                                                  |  |   |       |  

The entire $3.4 million of unrecognized tax benefits at December 31, 2007 would reduce income
tax expense if ultimately recognized. We do not expect any significant increases or decreases to our unrecognized tax benefits within 12 months of this reporting date.

Subsequent to adoption, interest and penalties incurred associated with unresolved income tax positions will be included in income tax expense. Accrued interest and penalties are insignificant.

We conduct business globally and, as a result, file numerous consolidated and separate income tax returns in the U.S. federal jurisdiction and various
state and foreign jurisdictions. In the normal course of business, we are subject to examination by tax authorities throughout the world, including such major jurisdictions as the U.S., United Kingdom, France and Japan. We are subject to U.S.
federal, state and local, or non-U.S. income tax examinations for years after 2003. However, carryforward attributes that were generated prior to 2003 may still be adjusted by a taxing authority upon examination if the attributes have been or will
be used in a future period.

12. Employee Benefit Plan

401(k) Retirement Savings Plan

All our employees in the U.S. are eligible to participate in our 401(k) Plan. Terms of the
401(k) Plan permit an employee to contribute up to a maximum of 16% of an employees annual compensation on a post-tax or pre-tax basis, up to the maximum permissible by the Internal Revenue Service during any plan year. We match

each employees contribution in increments equivalent to 100% for the first 3% and 50% for the second 3% of the employees contribution percentage.
In 2007, 2006 and 2005 we contributed $1.2 million, $1.3 million and $1.0 million in matching contributions to the 401(k) Plan in accordance with the plans terms. Employees immediately vest in the contributions the employee makes. Vesting in
our contribution on behalf of the employee occurs at equal increments at the end of each year of the first five years of an employees service with us.

13. Commitments and contingencies

Indemnification Obligations and Guarantees (excluding product warranty)

We provide (i) indemnifications of varying scope and size to our customers and distributors against claims of intellectual property infringement made
by third parties arising from the use of our products; (ii) indemnifications of varying scope and size to our customers against third party claims arising as a result of defects in our products; (iii) indemnifications of varying scope and
size to consultants against third party claims arising from the services they provide to us; and (iv) guarantees to support obligations of some of our subsidiaries such as lease payments. These indemnifications and guarantees require only
disclosure. To date, we have not incurred material costs as a result of these obligations and do not expect to incur material costs in the future. Accordingly, we have not accrued any liabilities in our consolidated financial statements related to
these indemnifications or guarantees.

Operating leases

We currently lease office and manufacturing space, automobiles and office equipment under operating leases. As of December 31, 2007, future minimum lease payments are as follows (in thousands):



|           |  |   |       
|---------- |  | - | ------
|2008       |  | $ | 3,320 
|2009       |  |   | 3,013 
|2010       |  |   | 2,502 
|2011       |  |   | 2,359 
|2012       |  |   | 2,247 
|Thereafter |  |   | 2,703 
|           |  |   |       
|Total      |  | $ | 16,144
|           |  |   |       

Rent expense for the years ended December 31, 2007, 2006 and 2005 was $3.2 million, $2.8
million and $2.7 million.

Other commitments

In 2005, we entered into an agreement to contribute up to $1.0 million to a research university. This pledge, which is to be paid over a four-year period, is conditioned upon our election to make a payment on an annual basis. We contributed
$0.3 million in 2007, $0.3 million in 2006 and $0.1 million in 2005.

As part of our agreements with our suppliers, suppliers may procure
resources and material expected to be used for the manufacture of our product in accordance with our production schedule provided to them. In the event these items are not used in the quantities submitted as part of the production schedule or
material becomes obsolete as a result of production timing, material changes or design changes, we may be responsible for compensating our suppliers for these procurements. As of December 31, 2007, these commitments were not significant.

13. Commitments and contingencies(Continued)



At December 31, 2007 we maintained a deposit of $1.0 million with our bank in the United Kingdom
as security for payment of customs and duties charges. At December 31, 2006 this amount was $0.6 million. These amounts are included in other long-term assets.

In the U.S., we have complemented our direct sales efforts by entering into group purchasing agreements with major healthcare group purchasing organizations (GPO). Typically, a GPO negotiates with medical
suppliers, such as us, on behalf of the GPOs member healthcare facilities, providing such members with uniform pricing and terms and conditions. In exchange, the GPO identifies us as a preferred supplier for its members. Member facilities
participating in the GPOs purchasing program can consist of hospitals, medical group practices, nursing homes, surgery centers, managed care organizations, long term care facilities, clinics and integrated delivery networks. Currently, we have
GPO supply agreements with various groups including AmeriNet, Inc., Premier, Inc., Novation LLC, MedAssets HSCA, Inc., Broadlane, Inc. (includes Kaiser Permanente, Tenet Healthcare and others) Consorta, Inc. and ROI/Sisters of Mercy and First
Choice. These agreements require us to pay fees based on the amount of sales generated from these agreements. For the years ended December 31, 2007, 2006 and 2005, we recorded fees related to these agreements as sales and marketing expenses in
the amounts of $1.8 million, $1.4 million and $1.0 million, respectively.

Contingencies

We filed a patent infringement suit against Zonare Medical Systems, Inc. in the federal district court of the Central District of California alleging that
Zonare infringed one of our key patents through sales of its z.one ultrasound system. On March 14, 2007, Zonare filed an answer to our claim which included a counterclaim against us alleging that our products infringe its patent related to its
portable docking station.

On May 15, 2007, GE Healthcare, a competitor of ours, filed a lawsuit against us in the federal district
court in the Western District of Wisconsin. The lawsuit alleges that our MicroMaxx and/or TITAN products willfully infringe certain of GEs U.S. patents relating to ultrasound technology. GE is seeking unspecified monetary damages and an
injunction. On July 5, 2007, we filed a counterclaim against GE and certain of its affiliates. In parallel, we filed our answer to the complaint denying all of GEs claims and alleging that the asserted patents are either invalid, not
infringed, or both. Subsequent to these initial filings, both parties supplemented their claims with additional allegations of patent infringement. Our complaint also seeks unspecified monetary damages and a court injunction against future
infringement by GE and its affiliates.

We have not accrued any amounts for potential losses related to these matters. Because of
uncertainties related to the potential outcome and any range of loss on the pending litigation, management is unable to make a reasonable estimate of the liability that could result from an unfavorable outcome. As additional information becomes
available, we will assess the potential liability related to these matters. If and when we determine that a negative outcome of such matters is probable and reasonably estimable we will record accruals for losses. Our estimates regarding such losses
could differ from actual results. Revisions in our estimates of the potential liability could materially impact our results of operations, financial position and cash flow. We expense legal costs as incurred.

14. Related party transaction

In January 2007, we
accepted 4,560 shares of common stock valued at approximately $133,000 along with cash from our President and Chief Executive Officer as payment of the exercise price for 19,218 options, pursuant to the terms of the 1998 plan. The shares were valued
at the closing stock price on the date of the transaction.

15. Segment reporting

We currently have one reportable segment. We market our products in the United States and internationally through our direct sales force and our indirect distribution channels. Our chief operating decision maker
evaluates resource allocation decisions and our performance based upon revenue recorded in geographic regions and does not receive financial information about expense allocation on a disaggregated basis. Geographic regions are determined by the
shipping destination. Revenue by geographic location for the years ended December 31 is as follows (in thousands):

for the interim period presented.

As of December 31, 2007, our chief executive officer and our chief financial officer have evaluated the
effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934 (the Exchange Act), and they have concluded that our disclosure controls and procedures were effective to
ensure that the information required to be disclosed by us in reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange
Commission.

(b) Managements report on internal control over financial reporting

Our management is responsible for establishing and maintaining adequate internal controls over financial reporting as defined in Rules 13a-15(f) and
15d-15(f) under the Exchange Act. 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, 2007 as required by the Exchange Act Rule 13a-15(c). Our managements evaluation and assessment of our internal control over financial reporting concluded that, as of December 31, 2007, our
internal controls over financial reporting were effective. In making this assessment, our management used the criteria issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal ControlIntegrated
Framework.

KPMG LLP, an independent registered public accounting firm, has issued an audit report on the effectiveness of our internal
control over financial reporting. Their report is included in Item 8. in the section titled Reports of Independent Registered Public Accounting Firm.

(c) Changes in internal control over financial reporting

During 2007, we have made various
improvements to our system of internal control. We continue to review, revise and improve the effectiveness of our internal controls including strengthening our income tax provision review control procedure noted below. We have made no changes,
other than the items noted below, in the Companys internal controls over financial reporting in connection with our fourth quarter evaluation that would materially affect, or are reasonably likely to materially affect, our internal control
over financial reporting.

During our second quarter of 2007, we hired an employee dedicated solely to the area of taxes, who has the
background and expertise to strengthen our tax provision preparation process. In addition, we continued to use a third party tax firm to provide additional expertise related to accounting and reporting for income taxes.



|ITEM 9B. | OTHER INFORMATION
|-------- | -----------------

For each of the executive
officers named in the 2008 proxy statement under the heading Executive Officers, we have entered into change-in-control agreements. These agreements are substantially similar to each other. We will file the proxy statement within 120
days of December 31, 2007.
