Newborn Hearing Screening

Overview

Hearing impairment is the most common treatable chronic disorder in newborns, affecting as many as five babies out of every 1,000
newborns.  It  is  estimated  that  20,000  hearing-impaired  babies  are  born  in  the  United  States  (“U.S.”)  every  year,  and  as  many  as  60,000
more in the rest of the developed world. Until the introduction of universal newborn hearing screening programs, screening was generally
performed only on those newborns that had identifiable risk factors for hearing impairment. However, screening only those newborns with
risk factors for hearing impairment overlooks approximately half of newborns with some level of hearing impairment.

Early  identification  of  hearing  impairment  and  early  intervention  has  been  shown  to  improve  language  development  significantly.
Undetected  hearing  impairment  often  results  in  the  failure  to  learn,  process  spoken  language,  and  speak.  If  hearing  impairment  is  not
detected prior to discharge from the hospital it is often not detected until the child is 18 months of age or older. A 1997 study conducted at
the University of Colorado, Boulder evaluated the impact of hearing impairment on language and speech. All of the children evaluated in
the study were born with a hearing impairment but differed by the age at which the hearing impairment was detected. The study concluded
that those children whose hearing loss was detected early and who received appropriate treatment had significantly better language skills
and vocabularies than those children whose hearing loss was detected later.

Newborn Hearing Screening in the United States

We  estimate  that  today  approximately  95%  of  the  children  born  in  the  U.S.  are  being  screened  for  hearing  impairment  prior  to
discharge  from  the  hospital.  In  1999,  the American Academy  of  Pediatrics  Task  Force  on  Newborn  and  Infant  Hearing  first  published
specific guidelines for universal newborn hearing screening programs. In 2000 and 2007, the Joint Committee on Infant Hearing (“JCIH”)
Position Statements outlined principles, guidelines, and benchmarks for early hearing detection and intervention programs. These principles
and  guidelines  are  considered  the  standard  of  care  today.  Because  “positive”  results  are  referred  to  an  audiologist  or  an  Ear,  Nose  and
Throat  physician  (“ENT”)  for  additional  testing  and  evaluation,  limiting  the  number  of  “refers”  stemming  from  false  positive  results
reduces the cost of a newborn screening program. In addition, false positive results can cause unnecessary emotional distress for parents.

The 2007 JCIH Position Statement updated and expanded the definition of targeted hearing loss and recommended a specific protocol
for babies admitted to the Neonatal Intensive Care Unit (“NICU”) for more than 5 days. Additionally, the document expressed increased
awareness, not only of the need for diagnostic audiology evaluation for children diagnosed with hearing impairment at birth, but also for
surveillance and hearing screening for children at risk of delayed onset and progressive hearing impairment during the first three years of
life.

Newborn Hearing Screening Techniques

The  two  traditional  technologies  used  to  screen  newborns  and  infants  for  hearing  impairment  are  auditory  brainstem  response  and

otoacoustic emissions.

Auditory  brainstem  response  (“ABR”).        ABR  technology  is  the  most  accurate  and  comprehensive  method  for  screening  and
diagnosing  hearing  impairment. ABR  technology  is  based  on  detecting  the  brain’s  electric  impulses  resulting  from  a  specific  auditory
stimulus. ABR screening devices, used for newborn hearing screening, detect and analyze the brainwave response resulting from audible
click stimuli presented to the

3

 
Table of Contents

infant’s ears. Automated Auditory Brainstem Response (“AABR”) devices were developed to automatically analyze the ABR waveform
resulting from the auditory stimuli with computerized detection algorithms and statistical analysis. These devices can be used by any level
of hospital personnel with a minimal amount of training and will deliver a clinically valid and accurate screen. The detection algorithms
indicate  a  PASS  or  REFER  result  that  requires  no  interpretation,  thereby  reducing  staffing  requirements,  test  times,  and  total  hearing
screening program costs. A REFER test result indicates that the patient should be referred to an Audiologist or ENT for further diagnostic
evaluation.

Otoacoustic emission (“OAE”).        OAEs  are  sounds  created  by  the  active  biomechanical  processes  within  the  sensory  cells  of  the
cochlea. They occur both spontaneously and in response to acoustic stimuli. OAE screening uses a probe placed in the ear canal to deliver
auditory stimuli and to measure the response of the sensory cells with a sensitive microphone. OAE screening devices have technology that
allows  them  to  discriminate  between  randomly  occurring  OAEs,  OAEs  created  by  interfering  room  noise  present  in  the
test environment, and the OAEs that are a response to specific test stimuli. Automated OAE screening devices are capable of filtering non-
specific OAEs in order to detect and analyze the OAEs that lead to an accurate screen of the infant’s hearing. While a PASS test result
indicates a proper functioning cochlea, a REFER test result indicates that the OAEs are absent or small compared to normal data. A REFER
test  result  indicates  that  the  patient  should  be  referred  to  an Audiologist  or  ENT  for  further  diagnostic  evaluation.  OAE  technology  is
unable to detect hearing disorders affecting the neural pathways, such as auditory neuropathy. Estimates of the incidence rate of auditory
neuropathy among hearing impaired newborns vary widely, but are thought to be in the range of 5% to 15%.

Newborn Hearing Screening Product Lines

Our  newborn  hearing  screening  product  lines  consist  of  the ALGO, ABaer, AuDX,  and  Echo-Screen  newborn  hearing  screeners.
These hearing screening products utilize proprietary signal detection technologies to provide accurate and non-invasive hearing screening
for  newborns  and  are  designed  to  detect  hearing  loss  at  35  dB  nHL  or  higher.  Each  of  these  devices  is  designed  to  generate  a  PASS  or
REFER result.

•

•

•

  ALGO 5 and 3i Newborn Hearing Screeners.     These AABR devices deliver thousands of soft audible clicks to the newborn’s
ears  through  sound  cables  and  disposable  earphones  connected  to  the  instrument.  Each  click  elicits  an  identifiable  brain  wave,
which is detected by disposable electrodes placed on the head of the child and analyzed by the screening device. These devices
use our proprietary AABR signal detection algorithm.

  ABaer Newborn Hearing Screener.     The ABaer, which is a PC-based newborn hearing screening device, offers a combination
of AABR,  OAE,  and  diagnostic ABR  technologies  in  one  system.  The  automatic ABR  technology  utilizes  our  patented  Point
Optimized Variance Ratio (“POVR”) signal detection algorithm developed by the House Ear Institute. Like our ALGO newborn
hearing screeners, this device delivers thousands of soft audible clicks to the newborn’s ears through sound cables and disposable
earphones. Each click elicits an identifiable brain wave, which is detected by disposable electrodes placed on the head of the child
and  analyzed  by  the  screening  device.  The ABaer  OAE  software  is  the  same  technology  used  in  our AuDX  product  and  the
diagnostic ABR software is the same technology used in our Navigator diagnostic hearing assessment product.

  AuDX  and  Echo-Screen.     Our AuDX  product  is  a  hand-held  OAE  screening  device  that  can  be  used  for  newborn  hearing
screening, as well as for patients of all ages, from children through adults. Our Echo-Screen product is a hand-held combination
AABR and OAE device for newborn screening that can also used for children through adults in OAE-only mode. These devices
record and analyze OAEs generated by the cochlea through sound cables and disposable ear probes inserted into the patient’s ear
canal. OAE technology is unable to detect hearing disorders affecting the neural pathways, such as auditory neuropathy.

Diagnostic Hearing Assessment

Overview

We design and manufacture a variety of products used to screen for or diagnose hearing loss, or to identify abnormalities affecting the
peripheral  and  central  auditory  nervous  systems  in  patients  of  all  ages.  The  technology  used  in  most  of  these  systems  is  either
electrodiagnostic in nature or measures a response from the cochlea known as an OAE.

Electrodiagnostic  systems  record  electrical  activity  generated  in  the  central  nervous  system.  An  electrodiagnostic  testing  device
delivers acoustic stimuli to the ears while electrodes placed on the scalp record the brain’s electrical response. The most common auditory
test performed with electrodiagnostic equipment is the ABR test. This test, which records brainwaves that correspond to responses from the
inner ear and brainstem, is used to screen for and define hearing loss characteristics, particularly for patients who cannot reliably respond to
standard  behavioral  tests  of  hearing,  either  verbally  or  through  motor  response.  A  technician  with  minimal  training  can  operate  an
instrument  that  performs  an  automated ABR  screening  test.  More  advanced ABR  testing  techniques  that  either  define  the  nature  of  the
hearing loss or that screen for other auditory abnormalities such as an acoustic tumor, require the expertise of a trained clinician, usually an
audiologist  or  an  ENT  physician,  an  understanding  of  the  technology  being  used,  and  the  ability  to  interpret  complex  waveforms  that
represent the brain’s electrical activity.

In  the  follow  up  evaluation  of  newborns  diagnosed  with  hearing  impairment,  the  clinician  can  distinguish  between  hearing
impairments caused by mechanical or sensory dysfunction of the ear versus auditory neuropathy. Recent studies confirm the importance of
making this distinction, as appropriate treatments for these impairments differ. One study showed that for patients diagnosed with auditory
neuropathy,  approximately  15%  reported  some  benefit  from  hearing  aids  for  language  learning,  while  improvement  in  speech
comprehension and language acquisition was reported in 85% of patients who received cochlear implants.

Diagnostic Hearing Assessment Product Lines

Our diagnostic hearing assessment products consist of the Navigator Pro system, the Scout Sport portable diagnostic device and the

AuDX PRO.

•

  Navigator PRO.     Our Navigator PRO for hearing assessment consists of a base system that is augmented by discrete software

utilizes  evoked  potentials,  which  are  electrical  signals  recorded  from  the  central  nervous  system  that  appear  in  response  to
repetitive  stimuli,  such  as  a  clicking  noise.  The  evoked  potentials  are  used  to  record  and  display  human  physiological  data
associated  with  auditory  and  hearing-related  disorders.  The  Navigator  Pro  System  can  be  used  for  patients  of  all  ages,  from
children  to  adults,  including  infants  and  geriatric  patients.  The  device  can  be  configured  with  additional  proprietary  software

  Electromyography or “EMG”—Equipment that measures electrical activity in nerves, muscles, and the spinal cord.

  Intra-operative Monitoring or “IOM”—Products that assist surgeons in preserving the functional integrity of a patient’s nervous
system during and after complex surgical procedures.

  Polysomnography  or  “PSG”—Equipment  that  measures  a  variety  of  respiratory  and  neurological  functions  to  assist  in  the
diagnosis and monitoring of sleep disorders, such as snoring and obstructive sleep apnea, a condition that causes a person to stop
breathing intermittently during sleep.

  Balance  and  Mobility—Systems  to  diagnose  and  assist  in  treating  balance  disorders  in  an  evidence-based,  multidisciplinary
approach.

Diagnostic EEG Monitoring

Overview

We design, manufacture, and market a full line of computerized instruments used to help diagnose the presence of seizure disorders
and epilepsy, look for causes of confusion, evaluate head injuries, tumors, infections, degenerative diseases, and metabolic disturbances that
affect the brain, and assist in surgical planning. This type of testing is also done to diagnose brain death in comatose patients. These systems
and instruments work by detecting, amplifying, and recording the brain’s electrical impulses (EEGs). Routine EEG recording is done by
placing electrodes on a patient’s scalp over various areas of the brain to record and detect patterns of activity and specific types of electrical
events. EEG technologists perform the tests, and neurologists review and interpret the results.

Routine outpatient EEG testing is performed in both hospital neurology laboratories and physician offices, providing physicians with
a clinical assessment of a patient’s condition. For patients with seizures that do not respond to conventional therapeutic approaches, long-
term inpatient testing of EEGs and behavior is used to determine if surgical solutions are appropriate.

Diagnostic Electromyography Monitoring

Overview

Electromyography (“EMG”) involves the measurement of electrical activity of muscles both at rest and during contraction. Measuring
the electrical activity in muscles and nerves can help diagnose diseases that damage muscle tissue or nerves. An electromyogram is done to
determine if there is any disease present that damages muscle tissue, nerves, or the junctions between nerve and muscle (neuromuscular
junctions). An electromyogram can also be used to diagnose the cause of weakness, paralysis, and muscle twitching and is also used as a
primary diagnosis for carpal tunnel syndrome, which is the most frequently encountered peripheral compressive neuropathy.

Intra Operative Monitoring

Overview

Intra-operative  monitoring  (“IOM”)  is  the  use  of  electrophysiological  methods  such  as  EMG  and  EEG  to  monitor  the  functional
integrity of neural structures (i.e. brain, nerves, spinal cord) during surgery. The most common applications are in neurosurgery such as
spinal surgery, some brain surgeries, ENT procedures, and peripheral nerve surgery. IOM is used to localize neural structures and test the
function of these structures for early detection of intra-operative injury, allowing for immediate corrective measures.

Diagnostic Polysomnography Monitoring

Overview

Increasing  public  awareness  of  sleep  disorders  has  made  sleep  medicine  a  rapidly  growing  specialty.  Polysomnography  (“PSG”),
which  involves  the  analysis  of  respiratory  patterns,  brain  electrical  activity  and  other  physiological  data,  has  proven  critical  for  the
diagnosis and treatment of sleep-related diseases such as apnea, insomnia, and narcolepsy. A sleep study entails whole-night recordings of
brain  electrical  activity,  muscle  movement,  airflow,  respiratory  effort,  oxygen  levels,  electrical  activity  of  the  heart  (ECG  or  EKG),  and
other parameters. These recordings typically result in over 1,000 pages of data that are reviewed, analyzed, and scored by a technician, and
summarized in a report for the physician. We market configured laboratory systems, portable systems, and ambulatory recorders for home
monitoring.

Diagnostic PSG Monitoring Product Lines

Our  diagnostic  PSG  monitoring  products  can  be  used  individually  or  as  part  of  a  networked  system  for  overnight  sleep  studies  to

patient’s bedside or from the monitoring room.

We also market a broad line of disposable products and accessories for the PSG laboratory. The Airflow Pressure Transducer uses
pressure changes as an indicator of patient airflow levels, as contrasted to other monitoring devices that use temperature to indicate these
levels. This product detects shallow breathing in situations where temperature related transducers might remain substantially unchanged.
This method has been documented in industry publications to produce the signature waveform used in identifying a respiratory disorder
known as Upper Airway Resistance Syndrome.

Balance and Mobility

Overview

Balance disorders impact a large percentage of the population in all age ranges from children to adults. Common complaints include
dizziness, vertigo, or an inability to walk or drive a vehicle, which can all lead to the curtailment of daily life activities. These symptoms
are exacerbated in elderly patients and can result in falls, orthopedic injuries, and sometimes death.

Balance  problems  are  difficult  to  diagnose  and  treat  because  they  can  be  caused  by  a  combination  of  diseases  or  movement
dysfunctions.  Healthcare  professionals  who  take  a  traditional  clinical  approach  to  the  examination  and  treatment  of  balance  problems
typically  explore  one  component  of  the  balance  system  at  a  time.  This  approach  often  requires  patients  to  consult  multiple  specialists,
leading to patient dissatisfaction and increased health care costs, frequently without achieving an optimal outcome.

We believe the most effective strategy for diagnosing and treating balance disorders is an evidence-based, multidisciplinary approach
applying a broad range of patient information. Our Balance Manager systems are designed to facilitate the assessment and management of
complex balance problems in the context of the total patient to support this process. These systems are used in a broad spectrum of medical
disciplines including otolaryngology, neurology, physiatry, orthopedics/sports medicine, geriatrics, and physical rehabilitation.

Balance and Mobility Products

Our principal balance and mobility products are sold under the Neurocom brand:

•

  EquiTest.    Proprietary protocols in the EquiTest family of devices objectively quantify and differentiate among sensory, motor,
and  central  adaptive  impairments  to  balance  control.  This  approach  is  commonly  referred  to  as  computerized  dynamic
posturography (“CDP”). CDP is complementary to clinical tests designed to localize and categorize pathological mechanisms of
balance disorders in that it can identify and differentiate the functional impairments associated with the identified disorders.

  Balance Master.    A family of devices providing objective assessment and retraining of the sensory and voluntary motor control
of balance. With visual biofeedback on either a stable or dynamic support surface and in a stable or dynamic visual environment,
the clinician can both assess and retrain patients performing tasks ranging from essential daily living activities through high-level
athletic  skills.  The  objective  data  captured  by  the  device  supports  the  design  of  effective  treatment  and/or  training  programs
focused on the specific sensory and motor components underlying a patient’s functional limitations.

ability to live and move safely in a dynamic world and to participate in daily-life functions such as driving, walking through a
grocery store, or actively engaging in family activities.

Newborn Care

Newborn Care Products

We manufacture a wide variety of products used in the medical care of newborns. These product lines include products to diagnose
and treat newborn brain injury, as well as phototherapy lights to treat newborn jaundice. We also sell a variety of newborn care products to
meet the needs of clinicians in the nursery and NICU. With our recent acquisition of Medix, we now offer a full range of thermoregulation
devices use for the care of newborns.

Newborn Brain Injury

Overview

For many years, newborn infants admitted to the NICU of a hospital have routinely been monitored for heart activity, temperature,
respiration,  oxygen  saturation,  and  blood  pressure.  Only  recently  has  it  also  been  considered  important  to  monitor  brain  activity  using
continuous  EEG. A  cerebral  function  monitor,  utilizing  amplitude-integrated  EEGs  (“aEEGs”),  is  a  device  for  monitoring  background
neurological activity.

Neurological Assessment and Treatment Options

Early diagnosis of brain injury in newborns, when combined with early intervention, has been shown to reduce the severity of these
brain  injuries  and  in  some  cases,  save  the  patient’s  life.  These  brain  injuries,  which  can  occur  in  as  many  as  three  out  of  every  1,000
newborns,  are  caused  by  conditions  such  as  hypoxic  ischemic  encephalopathy  (“HIE”),  subclinical  seizures,  or  neurological  disorders.
Diagnosing these conditions shortly after birth is imperative, as patients who undergo therapy within six hours after birth show a greater
potential for improved outcomes. We believe that diagnoses utilizing aEEG technology can have a marked and positive impact upon the
outcomes of some newborns suffering from brain injury.

Newborn Brain Injury Diagnostic Products

Our  newborn  brain  injury  diagnostic  products  record  and  display  parameters  that  the  neonatologist  uses  to  diagnose  neurological
disorders  or  brain  injury  in  the  newborn.  These  devices  continuously  monitor  and  record  brain  activity,  aiding  in  the  detection  and
treatment of HIE and seizures. The devices also monitor the effects of drugs and other therapies on brain activity and improve the accuracy
of newborn neurological assessments. They are used with electrodes attached to the head of the newborn to acquire an EEG signal that is
then  filtered,  compressed,  and  displayed  graphically  on  the  device  or  as  a  hardcopy  printout.  The  monitors  have  touch  screens  for  easy
navigation and onscreen keyboards for data entry at the bedside.

  Olympic Brainz Monitor.    The Olympic Brainz Monitor (“OBM”) is our latest generation Cerebral Function Monitor (“CFM”).
The  device  can  be  used  as  a  single  channel,  two-channel  or  three-channel  device  to  continuously  monitor  and  record  brain
activity. The OBM displays up to three channels of both aEEG and EEG data. Sophisticated networking, archiving and viewing
functions  facilitate  consultation  among  medical  professionals.  Continuous  impedance  and  corresponding  EEG  signals  are  also
displayed, aiding better clinical management of the newborn.

  Brainz BRM3.    The Brainz BRM3 is a bedside monitor that collects and measures electrical activity from both the right and left
hemispheres of the brain. The monitor presents a simplified 2-channel EEG display, along with the option to view three channels
of time-compressed amplified EEG’s (“aEEG”), providing practitioners with the ability to monitor infants with a wider variety of
neurological concerns

transport to a tertiary-care center.

Newborn Brain Injury Treatment

•

  Olympic  Cool-Cap  System.        The  Olympic  Cool-Cap  is  the  only  FDA-approved  device  for  the  treatment  of  moderate  to
moderately-severe HIE. A four-year clinical trial for the Cool-Cap was completed in 2003, and the FDA approved the product in
December 2006. The clinical trial validated the benefit of selective head cooling as a means of reducing the temperature of the
brain to diminish the severity of brain injury resulting from HIE in newborns. The device conforms to the clinical trial protocol
and is designed to assist the clinician in safely administering treatment, thereby preventing or significantly reducing the severity
of neurological injury associated with HIE. The Olympic Cool-Cap brain cooling system uses a single-patient, disposable, cooling
“cap” to continuously circulate sterile water to the patient during the 72-hour treatment period.

Thermoregulation Products

Overview

Incubators  offer  a  controlled,  consistent  microenvironment  for  thermoregulation  and  humidification  within  a  closed  system  to
maintain  skin  integrity  and  body  temperature.  This  controlled  microenvironment  reduces  noise  and  light,  supporting  developmental  care
while still providing access for clinical staff and family. Closed incubators are used for premature or sick babies who need a thermal and
developmental environment to thrive and grow in the NICU. Transport incubators are designed to offer a controlled environment during
transport  either  intra-hospital  from  one  care  area  to  another  within  a  hospital  building  or  inter-hospital  between  hospitals.  Open  infant
warmers are the preferred device for labor and delivery rooms and NICU admission.

We currently offer the following thermoregulation products:

Jaundice Management

Overview

The American Academy of Pediatrics estimates that each year 60% of the approximately four million newborns in the U.S. become
jaundiced.  According  to  the  Journal  of  the  American  Medical  Association,  neonatal  jaundice  is  the  single  largest  cause  for  hospital
readmission of newborns in the U.S., and accounts for 50% of readmissions. Because of the serious consequences of hyperbilirubinemia,
the American Academy of Pediatrics recommends that all newborns be closely monitored for jaundice and has called for the physician to
determine the presence or absence of an abnormal rate of hemolysis to establish the appropriate treatment for the newborn.

11

 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

In  2004,  the American Academy  of  Pediatrics  issued  new  guidelines  for  the  treatment  of  jaundice  in  newborns.  The  guidelines
recommend phototherapy as the standard of care for the treatment of hyperbilirubinemia in infants born at 35 weeks or more of gestation.
The  guidelines  further  highlight  the  need  for  “intense”  phototherapy,  and  specifically  recommend  the  use  of  the  “blue”  light  treatment
incorporated into our neoBLUE products.

Jaundice Management Products

  neoBLUE Product Family.    This product line consists of our neoBLUE, neoBLUE Mini, and neoBLUE Cozy devices, which
utilize light emitting diodes (“LEDs”) to generate a high-intensity, narrow spectrum of blue light that is clinically proven to be
most effective in the treatment of newborn jaundice. The neoBLUE phototherapy devices emit significantly less ultraviolet light
and  heat  than  conventional  phototherapy  devices,  reducing  the  risk  of  skin  damage  and  dehydration  for  infants  undergoing
treatment. Because of the high intensity of these lights, the treatment time associated with phototherapy is reduced.

  Bili-Lite  Product  Family.        These  devices  utilize  fluorescent  light  bulbs  for  the  treatment  of  hyperbilirubinemia.  The  Bili-
Bassinet provides intensive phototherapy from both under and over the baby for maximum surface area coverage. The Bili-Lite
pad is a product designed for both hospital and home-based phototherapy.

  MediLED Product Family.    This product line from Medix includes a full-size, free-standing LED phototherapy system and a
MediLED mini light to be used on top of an incubator or attached to the Medix radiant warmer. The MediLED incorporates an
array of blue and white LEDs, while the mini system utilizes blue “super LEDs” that provide high intensity phototherapy.

  Newborn Screening Data Management Product Line.    Our suite of newborn screening data management products consists of
proprietary software that collects, tracks, manages and reports newborn screening data to regional government health laboratories
and  national  disease  control  centers.  While  all  states  have  laws  and/or  regulations  requiring  newborn  screening  for  metabolic
disorders, the laws and regulations vary widely in the extent of screening required. Some states use tandem mass spectrometry in
their  newborn  metabolic  screening  programs,  which  increases  the  number  of  treatable  disorders  that  can  be  detected.  Revenue
from installation and upgrades of our newborn screening data management systems is classified as devices and systems revenue,
and revenue from maintenance contracts on the systems is classified as supplies and services revenue.

  Print and direct mail advertising campaigns; and

  Sponsorship of and participation in clinical education seminars and workshops.

Educational efforts directed at government agencies, physicians, and clinicians about the benefits of universal screening in terms of

patient outcomes and long-term treatment costs are a key element of our marketing strategy.

Domestic Direct and Distributor Sales

We  sell  our  products  in  the  United  States  primarily  through  a  direct  sales  organization.  We  believe  this  direct  sales  organization
allows us to maintain a higher level of customer service and satisfaction than would otherwise be possible by other distribution methods.
We also sell certain products under private label and distribution arrangements.

Domestic revenue as a percent of total revenue was 58%, 66%, and 69% in 2010, 2009 and 2008, respectively.

As a percent of total revenue, domestic sales through our direct and other sales channels, respectively, was 52% and 6% in 2010, 59%

and 7% in 2009, and 62% and 7% in 2008.

International Direct and Distributor Sales

We sell some of our products outside the U.S. through direct sales channels in Canada and in the French and German speaking regions
of  Europe,  in  Denmark,  and  in  parts  of  Latin America;  we  sell  other  products  in  those  regions  and  into  more  than  100  other  countries
through a distributor sales channel.

International revenue as a percent of total revenue was 42%, 34%, and 31% in 2010, 2009 and 2008, respectively.

As a percent of total revenue, international sales through our direct and other sales channels, respectively, was 17% and 25% in 2010,

11% and 23% in 2009, and 16% and 15% in 2008.

We sell products to our distributors under substantially the same terms as sales through our direct sales channels. Terms of sales to
international distributors are generally EXW, reflecting that goods are shipped “ex works,” in which title and risk of loss are assumed by
the distributor at the shipping point. Distributors are generally given exclusive rights in their territories to purchase products from Natus
and  resell  to  end  users  or  subdistributors.  Our  distributors  typically  perform  marketing,  sales,  and  technical  support  functions  in  their
respective  markets.  Each  distributor  may  sell  Natus  products  to  their  customer  directly,  via  other  distributors  or  resellers,  or  both.  We
actively train our distributors in product marketing, selling, and technical service techniques.

Seasonality in Revenue

We experience seasonality in our revenue. Our revenue typically drops from our fourth quarter to our first quarter. This seasonality
results from the purchasing habits of our hospital-based customers, whose purchases are often governed by calendar year budgets, and the
manner in which our direct sales force is compensated, as their compensation is based on annual sales plans that are tied to our December
year end.

Group Purchasing Organizations

More  than  90%  of  the  hospitals  in  the  U.S.  are  members  of  group  purchasing  organizations  (“GPO”s),  which  negotiate  volume

purchase agreements for member hospitals, group practices, and other clinics. Direct

14

 
 
 
 
 
 
Table of Contents

purchases by GPO members accounted for approximately 18%, 24% and 31% of our revenue in 2010, 2009 and 2008, respectively. Direct
purchases  by  members  of  one  GPO,  Novation,  accounted  for  approximately  6%,  8%  and  10%  of  our  revenue  in  2010,  2009  and  2008,
respectively.

Third-Party Reimbursement

In the U.S., health care providers generally rely on third-party payors, including private health insurance plans, federal Medicare, state
Medicaid,  and  managed  care  organizations,  to  reimburse  all  or  part  of  the  cost  of  the  procedures  they  perform.  Third-party  payors  can
affect the pricing or the relative attractiveness of our products by regulating the maximum amount of reimbursement these payors provide
for services utilizing our products. For this reason, we are not able to measure a reimbursement success rate for our products.

Customer Service and Support

We  provide  a  one-year  warranty  on  all  medical  device  products.  We  also  sell  extended  service  agreements  on  our  medical  device
products.  Service,  repair,  and  calibration  services  for  our  domestic  customers  are  provided  by  Company-owned  service  centers  and  our
field service specialists. Service for our international customers is provided by a combination of our Company-owned authorized service
centers and third-party vendors on a contract basis.

Manufacturing

Other  companies  manufacture  a  significant  portion  of  the  components  used  in  our  products;  however,  we  perform  final  assembly,
testing, and packaging of most of the devices ourselves to control quality and manufacturing efficiency. We also use contract vendors to
manufacture some of our disposable supply and medical device products. We perform regular quality audits of these vendors.

We  purchase  materials  and  components  from  qualified  suppliers  that  are  subject  to  our  quality  specifications  and  inspections.  We
conduct  quality  audits  of  our  key  suppliers,  several  of  which  are  experienced  in  the  supply  of  components  to  manufacturers  of  finished
medical devices, or supplies for use with medical devices. Most of our purchased components are available from more than one supplier.

Our manufacturing, service, and repair facilities are subject to periodic inspection by federal, state, and foreign regulatory authorities.
Our  quality  assurance  system  is  subject  to  regulation  by  the  FDA  and  other  state  government  agencies.  We  are  required  to  conduct  our
product design, testing, manufacturing, and control activities in conformance with the FDA’s quality system regulations and to maintain our
documentation of these activities in a prescribed manner. In addition, our production facilities have received ISO 13485 certification. ISO
13485 certification standards for quality operations have been developed to ensure that medical device companies meet the standards of
quality  on  a  worldwide  basis.  We  have  also  received  the  EC  Certificate  pursuant  to  the  European  Union  Medical  Device  Directive
93/42/EEC, which allows us to place a CE mark on our products.

Research and Development

We  are  committed  to  introducing  new  products  and  supporting  current  product  offerings  in  our  markets  through  a  combination  of

internal as well as external efforts that are consistent with our corporate strategy.

Internal product development capabilities.    We believe that product development capabilities are essential to provide our customers
with  new  product  offerings.  We  plan  to  leverage  our  core  technologies  by  introducing  product  line  extensions  as  well  as  new  product
offerings.

Partnerships  that  complement  our  expertise.    We  continue  to  seek  strategic  partners  in  order  to  develop  products  that  may  not
otherwise be available to us. By taking advantage of our core competencies, we believe that we can bring products to market in an efficient
manner and leverage our distribution channels.

technologies into successful new products.

in 2009, and $15.5 million or 9.6% of total revenue in 2008.

Proprietary Rights

We  protect  our  intellectual  property  through  a  combination  of  patent,  copyright,  trade  secret,  and  trademark  laws.  We  attempt  to
protect our intellectual property rights by filing patent applications for new features and products we develop. We enter into confidentiality
or  license  agreements  with  our  employees,  consultants,  and  corporate  partners,  and  seek  to  control  access  to  our  intellectual  property,
distribution  channels,  documentation,  and  other  proprietary  information.  However,  we  believe  that  these  measures  afford  only  limited
protection.

The intellectual rights to some of the original patents for technology incorporated into our products are now in the public domain.
However, we do not consider these patents, or any currently viable patent or related group of patents, to be of such importance that their
expiration or termination would materially affect our business.

We capitalize the cost of purchased technology and intellectual property, as well as certain costs incurred in obtaining patent rights,

and amortize these costs over the estimated economic lives of the related assets.

Competition

We sell our products in competitive and rapidly evolving markets. We face competition from other companies in all of our product
lines. Our competitors range from small privately-held companies to multinational corporations and their product offerings vary in scope
and breadth. We do not believe that any single competitor is dominant in any of our product lines.

We  derive  a  significant  portion  of  our  revenue  from  the  sale  of  disposable  supplies  that  are  used  with  our  medical  devices.  In  the
U.S.,  we  sell  our  supply  products  in  a  mature  market.  Because  these  products  can  generate  high  margins,  we  expect  that  our  products,
particularly our hearing screening supply products, could face increasing competition, including competitors offering lower prices, which
could have an adverse affect on our revenue and margins.

We believe the principal factors that will draw clinicians and other buyers to our products, include:

•

•

•

•

•

•

•

•

•

  Level of specificity, sensitivity, and reliability of the product;

  Time required to obtain results with the product, such as to test for or treat a clinical condition;

  Relative ease of use of the product;

  Depth and breadth of the products features;

  Quality of customer support for the product;

  Frequency of product updates;

  Extent of third-party reimbursement of the cost of the product or procedure;

  Extent to which the products conform to standard of care guidelines; and

  Price of the product.

Table of Contents

We  believe  that  our  primary  competitive  strength  relates  to  the  functionality  and  reliability  of  our  products.  Different  competitors
may have competitive advantages in one or more of the categories listed above and they may be able to devote greater  resources  to  the
development, promotion, and sale of their products.

Government Regulation

FDA’s Premarket Clearance and Approval Requirements

Unless an exemption applies, the medical devices we sell in the United States, with the exception of some disposable products, must

first receive one of the following types of FDA premarket review authorizations under the Food, Drug, and Cosmetics Act, as amended:

•

•

  Clearance via Section 510(k); or

  Premarket approval via Section 515 if the FDA has determined that the medical device in question poses a greater risk of injury.

The FDA’s 510(k) clearance process usually takes from three to 12 months, but can take longer. The process of obtaining premarket
approval via Section 515 is much more costly, lengthy, and uncertain. Premarket approval generally takes from one to three years, but can
take longer. We cannot be sure that the FDA will ever grant either 510(k) clearance or premarket approval for any product we propose to
market in the United States.

The  FDA  decides  whether  a  device  must  undergo  either  the  510(k)  clearance  or  premarket  approval  process  based  upon  statutory
criteria. These criteria include the level of risk that the Agency perceives to be associated with the device and a determination of whether
the product is a type of device that is substantially equivalent to devices that are already legally marketed. The FDA places devices deemed
to pose relatively less risk in either Class I or Class II, which requires the manufacturer to submit a premarket notification requesting 510(k)
clearance,  unless  an  exemption  applies.  The  premarket  notification  under  Section  510(k)  must  demonstrate  that  the  proposed  device  is
substantially  equivalent  in  intended  use  and  in  safety  and  effectiveness  to  a  previously  cleared  510(k)  device  or  a  device  that  was  in
commercial distribution before May 28, 1976 for which the FDA has not yet called for the submission of premarket approval applications.

The FDA places devices deemed to pose the greatest risk, such as life-sustaining, life-supporting or implantable devices, or devices
deemed to be not substantially equivalent to a predicate device, in its Class III classification. The FDA requires these devices to undergo the
premarket approval process via Section 515 in which the manufacturer must prove the safety and effectiveness of the device. A premarket
approval application must provide extensive pre-clinical and clinical trial data.

The  FDA  may  require  results  of  clinical  trials  in  support  of  a  510(k)  submission  and  generally  requires  clinical  trial  results  for  a
premarket approval application. In order to conduct a clinical trial on a significant-risk device, the FDA requires manufacturers to apply for
and  obtain,  in  advance,  an  investigational-device  exemption.  The  investigational-device  exemption  application  must  be  supported  by
appropriate  data,  such  as  animal  and  laboratory  testing  results.  If  the  FDA  and  the  Institutional  Review  Boards  at  the  clinical  trial  sites
approve  the  investigational-device  exemption  application  for  a  significant-risk  device,  the  manufacturer  may  begin  the  clinical  trial. An
investigational-device exemption approval provides for a specified clinical protocol, including the number of patients and study sites. If the
manufacturer  deems  the  product  a  non-significant  risk  device,  the  product  will  be  eligible  for  more  abbreviated  investigational-device
exemption requirements. If the Institutional Review Boards at the clinical trial sites concur with the non-significant risk determination, the
manufacturer may begin the clinical trial.

We received approval for our Olympic Cool-Cap product as a Class III device from the FDA through the premarket approval process.
Most of our other products have been cleared by the FDA as Class II devices. Some of our disposable products and newborn care products,
such as our neonatal headshields and oxygen delivery systems, have received FDA clearance as Class I devices.

FDA Regulation

Numerous FDA regulatory requirements apply to our products. These requirements include:

•

•

•

  FDA  quality  system  regulations  which  require  manufacturers  to  create,  implement,  and  follow  design,  testing,  control,

documentation, and other quality assurance procedures;

  Medical  device  reporting  regulations,  which  require  that  manufacturers  report  to  the  FDA  certain  types  of  adverse  and  other

events involving their products; and

  FDA general prohibitions against promoting products for unapproved uses.

Class  II  and  III  devices  may  also  be  subject  to  special  controls  applied  to  them,  such  as  performance  standards,  post-market
surveillance, patient registries, and FDA guidelines that may not apply to Class I devices. We believe we are in compliance with applicable
FDA guidelines, but we could be required to change our compliance activities or be subject to other special controls if the FDA changes
existing regulations or adopts new requirements.

We are subject to inspection and market surveillance by the FDA to determine compliance with regulatory requirements. If the FDA

finds that we have failed to adequately comply, the Agency can institute a wide variety of enforcement actions, including:

•

•

•

•

•

•

•

•

  Issuance of a Form 483 citation;

  Fines, injunctions, and civil penalties;

  Recall or seizure of our products;

  Issuance of public notices or warnings;

  Imposition of operating restrictions, partial suspension, or total shutdown of production;

  Refusal of our requests for 510(k) clearance or pre-market approval of new products;

  Withdrawal of 510(k) clearance or pre-market approval already granted; or

  Criminal prosecution.

The FDA also has the authority to require us to repair, replace, or refund the cost of any medical device manufactured or distributed

by us.

Other Regulations

We  also  must  comply  with  numerous  additional  federal,  state,  and  local  laws  relating  to  matters  such  as  safe  working  conditions,
manufacturing practices, environmental protection, biohazards, fire hazard control, and hazardous substance disposal. We believe we are
currently in compliance with such regulations.

Countries outside of the U.S. regulate medical devices in a manner similar to that of the FDA. Our manufacturing facilities are subject
to audit and have been certified to be ISO 13485:2003, Medical Device Directive 93/42/EEC, and CMDCAS compliant, which allows us to
sell our products in Canada, Europe, and other territories around the world. Our manufacturing facilities in North America are subject to
ISO 13485 inspections by our notified body, British Standards Institution Management Systems, and by other notified bodies outside of
North America. We plan to seek approval to sell our products in additional countries, while maintaining our current approvals. The time
and cost of obtaining new, and maintaining existing, market authorizations from countries outside of North America, and the requirements
for licensing products in these countries may differ significantly from FDA requirements.

Employees

On December 31, 2010, we had approximately 750 full time employees worldwide. In Argentina, some of our production employees
are  represented  by  labor  unions;  none  of  our  other  employees  are  so  represented.  We  have  not  experienced  any  work  stoppages  and
consider our relations with our employees to be good.

ITEM 1A. Risk Factors

We  have  completed  a  number  of  acquisitions  and  expect  to  complete  additional  acquisitions  in  the  future.  There  are  numerous
risks associated with acquisitions and we may not achieve the expected benefit of any of our acquisitions

Our acquisitions of products, technology assets, or businesses may have a negative impact on our business if we fail to achieve the

anticipated financial, strategic, and other benefits of acquisitions or investments, and our operating results may suffer because of this.

Our significant acquisitions are as follows: Neometrics in 2003; Fischer-Zoth in 2004; Bio-logic, Deltamed, and Olympic in 2006;

Xltek in 2007; Sonamed, Schwarzer Neurology, and Neurocom in 2008; Hawaii Medical and Alpine Biomed in 2009, and Medix in 2010.

20

 
 
Table of Contents

We expect to continue to pursue opportunities to acquire other businesses in the future. The acquisitions that we have completed may
not result in improved operating results for us, or in our achieving a financial condition superior to that which we would have achieved had
we not completed them. Our results of operations may be adversely impacted by costs associated with our acquisitions, including one-time
charges associated with restructurings. Further, our acquisitions could fail to produce the benefits that we anticipate, or could have other
adverse effects that we currently do not foresee. In addition, some of the assumptions that we have relied upon, such as achievement of
operating  synergies,  may  not  be  realized.  In  this  event,  one  or  more  of  the  acquisitions  could  result  in  reduced  earnings  of  Natus  as
compared to the earnings that would have been achieved by Natus if the acquisition had not occurred.

We have assumed contingent obligations associated with earnout provisions in some of our acquisitions. We believe these provisions
help us to negotiate mutually agreeable purchase terms between us and the sellers. However, a disagreement between us and a seller about
the terms of an earnout provision could result in our paying more for an acquisition then we intended. For example, such a disagreement
arose  in  connection  with  our  acquisition  of  Alpine  Biomed,  which  we  have  subsequently  resolved.  The  stockholders  of  Schwarzer
Neurology have recently asserted claims relating to the earnout provision of our agreement with those stockholders that have not yet been
resolved.  Disputes  over  these  types  of  contingent  obligations  may  not  be  resolved  on  terms  that  are  favorable  to  us  and  the  payment  of
additional purchase consideration could impact our results of operations and financial position.

We have incurred indebtedness to fund some of our acquisitions. The use of debt to fund our acquisitions may have an adverse impact
on our liquidity and cause us to place more reliance on cash flow from operations for our liquidity. If our cash flow from operations is not
sufficient for our needs, our business could be adversely affected. If we are required to seek additional external financing to support our
need for cash to fund future acquisitions, we may not have access to financing on terms that are acceptable to us, or at all. Alternatively, we
may  feel  compelled  to  access  additional  financing  on  terms  that  are  dilutive  to  existing  holders  of  our  common  stock  or  that  include
covenants that restrict our business, or both. If the recent lack of liquidity in credit markets persists into the future, our ability to obtain debt
financing for future acquisitions may be impaired.

If  we  fail  to  successfully  manage  the  combined  operations  of  Natus  and  the  businesses  we  have  acquired,  we  may  not  realize  the
potential  benefits  of  our  acquisitions.  Our  corporate  headquarters  are  located  in  San  Carlos,  California.  We  also  have  the  following
operating divisions: Olympic in Washington; Neurocom in Oregon; Bio-logic in Illinois; Neometrics in New York; Xltek and Stellate in
Canada;  Medix  in Argentina; Alpine  Biomed  in  Denmark;  Fischer-Zoth,  Schwarzer  Neurology,  IT-Med,  and Alpine  Biomed  Germany
(collectively “Natus Europe”) in Germany; and Deltamed and Alpine Biomed France (collectively “Natus France”) in France. If we fail to
manage these disparate operations effectively, our results of operations could be harmed, employee morale could decline, key employees
could leave, and customers could cancel existing orders or choose not to place new ones. In addition, we may not achieve the synergies or
other  benefits  of  these  and  future  acquisitions  that  we  anticipate.  We  may  encounter  the  following  additional  difficulties  and  delays
involved in integrating and managing these operations, and the operations of companies we may acquire:

•

•

•

•

•

•

•

  Failure of customers to continue using the products and services of the combined company;

  Failure to successfully develop the acquired technology into the desired products or enhancements;

  Assumption of unknown liabilities;

  Failure to understand products or technologies with which we have limited previous experience;

  Failure to compete effectively in new markets;

  Decreased liquidity, restrictive bank covenants, and incremental financing costs associated with debt we may incur to complete
future acquisitions; and

  Diversion of the attention of management from other ongoing business concerns.

21

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

Our reported operating results may suffer because of impairment charges incurred to write down the carrying amount of intangible

assets, including goodwill, generated as a result of the acquisitions.

Our  growth  in  recent  years  has  depended  substantially  on  the  completion  of  acquisitions  and  we  may  not  be  able  to  complete
acquisitions of this nature or of a relative size in the future to support a similar level of growth

The  acquisitions  that  we  have  completed  have  been  the  primary  source  of  our  growth  in  revenue  in  recent  years.  We  expend
considerable effort in seeking to identify attractive acquisition candidates and, upon doing so, to convince the potential target to consider a
sale  to  us  and,  ultimately,  to  negotiate  mutually  agreeable  acquisition  terms.  If  we  are  not  successful  in  these  efforts  in  the  future,  our
growth rate will not increase at a rate corresponding to that which we have achieved in recent years. Further, as we grow larger it will be
necessary to complete the acquisition of larger companies and product lines to support a growth similar to that which we have achieved in
the  past.  The  market  for  attractive  acquisitions  is  competitive  and  others  with  greater  financial  resources  than  we  have  may  be  better
positioned than we are to acquire desirable targets. Further, we may not be able to negotiate acquisition terms with target companies that
will allow us to achieve positive financial returns from the transaction.

Adverse economic conditions in markets in which we operate may harm our business

Unfavorable  changes  in  U.S.  and  international  economic  environments  may  adversely  affect  our  business  and  financial  results.
Economic  conditions  in  the  countries  in  which  we  operate  and  sell  products  worsened  and  global  financial  markets  subsequently
experienced significant volatility and declines throughout much of 2009. Although these conditions improved in 2010, we are unable to
foresee  when,  or  if,  these  factors  might  return  to  historical  levels.  During  challenging  economic  times,  and  in  tight  credit  markets,  our
customers may delay or reduce capital expenditures. This could result in reductions in sales of our products, longer sales cycles, difficulties
in collection of accounts receivable, slower adoption of new technologies, and increased price competition, all of which could impact our
results of operations and financial condition. In addition, we expect these factors will cause us to be more cautious in evaluating potential
acquisition opportunities, which could hinder our ability to grow through acquisition while these conditions persist.

We have initiated changes to our information systems that could disrupt our business and our financial results.

We  plan  to  continuously  improve  our  enterprise  resource  planning,  customer  relationship  management,  and  document  lifecycle
management systems to support the form, functionality, and scale of our business. These types of transitions frequently prove disruptive to
the underlying business of an enterprise and may cause us to incur higher costs than we anticipate. Failure to manage a smooth transition to
the new systems and the ongoing operations and support of the new systems could materially harm our business operations.

For example, we are currently in the process of implementing the rollout of an enterprise resource planning application (“ERP”) in
our European operating divisions. Until we have completed this ERP implementation, we will be dependent on multiple platforms. We may
experience difficulties in implementing the ERP and we may fail to gain the efficiencies the implementation is designed to produce. The
implementation could also be disruptive to our operations, including the ability to timely ship and track product orders to customers, project
inventory requirements, manage our supply chain and otherwise adequately service our customers.

Future changes in technology or market conditions could result in adjustments to our recorded asset balance for intangible assets,
including goodwill, resulting in additional charges that could significantly impact our operating results

Our balance sheet includes significant intangible assets, including goodwill and other acquired intangible assets. The determination of
related estimated useful lives and whether these assets are impaired involves significant judgment. Our ability to accurately predict future
cash flows related to these intangible assets might

22

 
Table of Contents

be  hindered  by  events  over  which  we  have  no  control.  Due  to  the  highly  competitive  nature  of  the  medical  device  industry,  new
technologies could impair the value of our intangible assets if they create market conditions that adversely affect the competitiveness of our
products. Any  future  determination  that  these  assets  are  carried  at  greater  than  their  fair  value  could  result  in  substantial  impairment
charges, which could significantly impact our operating results.

We may not be able to preserve the value of our intellectual property because we may not be able to protect access to it or we may
lose our intellectual property rights due to expiration of our licenses or patents

If we fail to protect our intellectual property rights or if our intellectual property rights do not adequately cover the technology we
employ, other medical device companies could sell products with features similar to ours, and this could reduce demand for our products.
We  protect  our  intellectual  property  through  a  combination  of  patent,  copyright,  trade  secret  and  trademark  laws.  Despite  our  efforts  to
protect  our  proprietary  rights,  others  may  attempt  to  copy  or  otherwise  improperly  obtain  and  use  our  products  or  technology.  Policing
unauthorized  use  of  our  technology  is  difficult  and  expensive,  and  we  cannot  be  certain  that  the  steps  we  have  taken  will  prevent
misappropriation.  Our  means  of  protecting  our  proprietary  rights  may  be  inadequate.  Enforcing  our  intellectual  property  rights  could  be
costly  and  time  consuming  and  may  divert  our  management’s  attention  and  resources.  Failing  to  enforce  our  intellectual  property  rights
could also result in the loss of those rights.

If health care providers are not adequately reimbursed for procedures conducted with our devices or supplies, or if reimbursement
policies change adversely, we may not be successful marketing and selling our products or technologies

Clinicians,  hospitals,  and  government  agencies  are  unlikely  to  purchase  our  products  if  they  are  not  adequately  reimbursed  for  the
procedures conducted with our devices or supplies. Unless a sufficient amount of conclusive, peer-reviewed clinical data about our products
has  been  published,  third-party  payors,  including  insurance  companies  and  government  agencies,  may  refuse  to  provide  reimbursement.
Furthermore, even if reimbursement is provided, it may not be adequate to fully compensate the clinicians or hospitals. Some third-party
payors  may  impose  restrictions  on  the  procedures  for  which  they  will  provide  reimbursement.  If  health  care  providers  cannot  obtain
sufficient  reimbursement  from  third-party  payors  for  our  products  or  the  screenings  conducted  with  our  products,  we  may  not  achieve
significant  market  acceptance  of  our  products. Acceptance  of  our  products  in  international  markets  will  depend  upon  the  availability  of
adequate  reimbursement  or  funding  within  prevailing  healthcare  payment  systems.  Reimbursement,  funding,  and  healthcare  payment
systems vary significantly by country. We may not obtain approvals for reimbursement in a timely manner or at all.

Adverse  changes  in  reimbursement  policies  in  general  could  harm  our  business.  We  are  unable  to  predict  changes  in  the
reimbursement methods used by third-party health care payors, particularly those in countries and regions outside the U.S. For example,
some payors are moving toward a managed care system in which providers contract to provide comprehensive health care for a fixed cost
per person. In a managed care system, the cost of our products may not be incorporated into the overall payment for patient care or there
may not be adequate reimbursement for our products separate from reimbursement for other procedures.

Healthcare  reforms,  changes  in  healthcare  policies,  and  changes  to  third-party  reimbursements  for  our  products  may  affect
demand for our products

In  March  2010  the  U.  S.  government  signed  into  law  the Patient  Protection  and  Affordable  Care  Act  and  the Health  Care  &
Education  Reconciliation  Act.  These  laws  are  intended  to,  among  other  things,  curb  rising  healthcare  costs,  including  those  that  could
significantly affect reimbursement for our products. The policies supporting these laws include: basing reimbursement policies and rates on
clinical outcomes; the comparative effectiveness and costs of different treatment technologies and modalities; imposing price controls; and
other measures. Future significant changes in the healthcare systems in the United States or elsewhere could also have a negative impact on
the demand for our current and future products. These include changes that may reduce

23

 
Table of Contents

reimbursement  rates  for  our  products  and  changes  that  may  be  proposed  or  implemented  by  the  U.S.  Presidential  administration  or
Congress.

There are numerous steps required to implement these laws. Because of the unsettled nature of these reforms, we cannot predict what
additional healthcare reforms will be implemented at the federal or state level, or the effect that any future legislation or regulation will
have on our business. There is also considerable uncertainty of the impact of these reforms on the medical device market as a whole. If we
fail to effectively react to the implementation of health care reform, our business may be adversely affected. In addition, if the excise tax on
the sale of medical devices is imposed as enacted, this could increase our costs and have an adverse effect on our  results  of  operations,
financial position, and cash flows.

If  we  fail  in  our  efforts  to  educate  clinicians,  government  agency  personnel,  and  third-party  payors  on  the  effectiveness  of  our
products, we may not achieve future sales growth

It  is  critical  to  the  success  of  our  sales  efforts  that  we  educate  a  sufficient  number  of  clinicians,  hospital  administrators,  and
government  agencies  about  our  products  and  the  costs  and  benefits  of  their  use.  The  commercial  success  of  our  products  depends  upon
clinician, government agency, and other third-party payer confidence in the economic and clinical benefits of our products as well as their
comfort with the efficacy, reliability, sensitivity and specificity of our products. We believe that clinicians will not use our products unless
they determine, based on published peer-reviewed journal articles and experience, that our products provide an accurate and cost-effective
alternative to other means of testing or treatment. Our customers may choose to use competitive products, which may be less expensive or
may  provide  faster  results  than  our  devices.  Clinicians  are  traditionally  slow  to  adopt  new  products,  testing  practices  and  clinical
treatments, partly because of perceived liability risks and the uncertainty of third-party reimbursement. If clinicians, government agencies
and  hospital  administrators  do  not  adopt  our  products,  we  may  not  maintain  profitability.  Factors  that  may  adversely  affect  the  medical
community’s acceptance of our products include:

•

•

•

•

•

•

  Publication of clinical study results that demonstrate a lack of efficacy or cost-effectiveness of our products;

  Changing governmental and physician group guidelines;

  Actual  or  perceived  performance,  quality,  price,  and  total  cost  of  ownership  deficiencies  of  our  products  relative  to  other
competitive products;

  Our ability to maintain and enhance our existing relationships and to form new relationships with leading physicians, physician
organizations, hospitals, state laboratory personnel, and third-party payers;

  Changes in state and third-party payer reimbursement policies for our products; and

  Repeal of laws requiring universal newborn hearing screening and metabolic screening.

Sales through group purchasing organizations and sales to high volume purchasers may reduce our average selling prices, which
could reduce our operating margins

We have entered, and expect in the future to enter into agreements with customers who purchase high volumes of our products. Our
agreements  with  these  customers  may  contain  discounts  from  our  normal  selling  prices  and  other  special  pricing  considerations,  which
could cause our operating margins to decline. In addition, we have entered into agreements to sell our products to members of GPOs, which
negotiate volume purchase prices for medical devices and supplies for member hospitals, group practices and other clinics. While we make
sales directly to GPO members, the GPO members receive volume discounts from our normal selling price and may receive other special
pricing considerations from us. Sales to members of all GPOs accounted for approximately 18%, 24% and 31% of our total revenue during
2010, 2009 and 2008, respectively, and sales to members of one GPO, Novation, accounted for approximately 6%, 8% and 10% of our total
revenue in 2010, 2009 and 2008, respectively. Other of our existing customers may be members of GPOs with which we do not

24

 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

have  agreements.  Our  sales  efforts  through  GPOs  may  conflict  with  our  direct  sales  efforts  to  our  existing  customers.  If  we  enter  into
agreements with new GPOs and some of our existing customers begin purchasing our products through those GPOs, our operating margins
could decline.

Demand for some of our products depends on the capital spending policies of our customers, and changes in these policies could
harm our business

A majority of customers for our products are hospitals, physician offices, and clinics. Many factors, including public policy spending
provisions, available resources, and economic cycles have a significant effect on the capital spending policies of these entities and therefore
the amount that they can spend on our equipment products. If budget resources limit the capital spending of our customers, they will be
unlikely  to  either  purchase  any  new  equipment  from  us  or  upgrade  to  any  of  our  newer  equipment  products.  Lack  of  liquidity  in  credit
markets  and  uncertainty  about  future  economic  conditions  can  have  an  adverse  effect  on  the  spending  patterns  of  our  customers.  These
factors can have a significant adverse effect on the demand for our products.

Our markets are very competitive and in the United States we sell certain of our products in a mature market

We face competition from other companies in all of our product lines. Our competitors range from small privately held companies to
multinational corporations and their product offerings vary in scope and breadth. We do not believe that any single competitor is dominant
in any of our product lines.

The markets for certain of our products in the U.S., including the newborn hearing screening and EEG monitoring markets, are mature
and we are unlikely to see significant growth for such products in the U.S. In the U.S. we derive a significant portion of our revenue from
the  sale  of  disposable  supplies  that  are  used  with  our  hearing  screening  devices.  Because  these  disposable  supply  products  can  generate
high  margins,  we  expect  that  our  products,  particularly  our  hearing  screening  disposable  supply  products,  could  face  increasing
competition, including competitors offering lower prices, which could have an adverse affect on our revenue and margins.

Our competitors may have certain competitive advantages, which include the ability to devote greater resources to the development,
promotion,  and  sale  of  their  products.  Consequently,  we  may  need  to  increase  our  efforts,  and  related  expenses  for  research  and
development, marketing, and selling to maintain or improve our position.

We expect recurring sales to our existing customers to generate a majority of our revenue in the future, and if our existing customers

do not continue to purchase products from us, our revenue may decline.

Our operating results may decline if we do not succeed in developing, acquiring, and marketing additional products or improving
our existing products

We intend to develop additional products and technologies, including enhancements of existing products, for the screening, detection,
treatment, monitoring and tracking of common medical ailments. Developing new products and improving our existing products to meet the
needs  of  current  and  future  customers  requires  significant  investments  in  research  and  development.  If  we  fail  to  successfully  sell  new
products, update our existing products, or timely react to changes in technology, our operating results may decline as our existing products
reach the end of their commercial life cycles.

Our plan to expand our international operations will result in increased costs and is subject to numerous risks; if our efforts are
not successful, this could harm our business

We have expanded our international operations through acquisitions and plan to expand our international sales and marketing efforts

to increase sales of our products in foreign countries. We may not realize

25

 
Table of Contents

corresponding growth in revenue from growth in international unit sales, due to the lower average selling prices we receive on sales outside
of the U.S. Even if we are able to successfully expand our international selling efforts, we cannot be certain that we will be able to create or
increase demand for our products outside of the U.S. Our international operations are subject to other risks, which include:

•

•

•

•

•

•

•

•

•

•

  Impact of possible recessions in economies outside the U.S.;

  Political and economic instability, including instability related to war and terrorist attacks;

  Contractual provisions governed by foreign law, such as local law rights to sales commissions by terminated distributors;

  Decreased healthcare spending by foreign governments that would reduce international demand for our products;

  Continued strengthening of the U.S. dollar relative to foreign currencies that could make our products less competitive because

approximately half of our international sales are denominated in U.S. dollars;

  Greater difficulty in accounts receivable collection and longer collection periods;

  Difficulties of staffing and managing foreign operations;

  Reduced protection for intellectual property rights in some countries and potentially conflicting intellectual property rights of third

parties under the laws of various foreign jurisdictions;

  Difficulty in obtaining and maintaining foreign regulatory approval; and

  Attitudes by clinicians, and cost reimbursement policies, towards use of disposable supplies that are potentially unfavorable to our

business.

In  particular,  our  international  sales  could  be  adversely  affected  by  a  strengthening  of  the  U.S.  dollar  relative  to  other  foreign

currencies, which makes our products more costly to international customers for sales denominated in U.S. dollars.

Our operating results may suffer because of our exposure to foreign currency exchange rate fluctuations

Substantially all of our sales contracts with our U.S. based customers provide for payment in U.S. dollars. With the exception of our
Canadian  operations,  substantially  all  of  the  revenue  and  expenses  of  our  foreign  subsidiaries  are  denominated  in  the  applicable  foreign
currency. To date we have executed only limited foreign currency contracts to hedge these currency risks. Our future revenue and expenses
may be subject to volatility due to exchange rate fluctuations that could result in foreign exchange gains and losses associated with foreign
currency transactions and the translation of assets and liabilities denominated in foreign currencies.

Substantially  all  our  sales  from  our  U.S.  operations  to  our  international  distributors  provide  for  payment  in  U.S.  dollars.  A
strengthening  of  the  U.S.  dollar  relative  to  other  foreign  currencies  could  increase  the  effective  cost  of  our  products  to  our  international
distributors as their functional currency is typically not the U.S. dollar. This could have a potential adverse effect on our ability to increase
or maintain average selling prices of our products to our foreign-based customers.

If guidelines mandating universal newborn hearing screening do not continue to develop in foreign countries and governments do
not  mandate  testing  of  all  newborns  as  we  anticipate,  or  if  those  guidelines  have  a  long  phase-in  period,  our  sales  of  newborn
hearing screening products may not achieve the revenue growth we have achieved in the past

We  estimate  that  approximately  95%  of  the  children  born  in  the  U.S.  are  currently  being  tested  for  hearing  impairment  prior  to
discharge  from  the  hospital.  To  date,  there  has  been  only  limited  adoption  of  newborn  hearing  screening  prior  to  hospital  discharge  by
foreign governments, and when newborn hearing screening

26

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

programs are enacted by foreign governments there can be a phase-in period spanning several years. The widespread adoption of guidelines
depends,  in  part,  on  our  ability  to  educate  foreign  government  agencies,  neonatologists,  pediatricians,  third-party  payors,  and  hospital
administrators about the benefits of universal newborn hearing screening as well as the use of our products to perform the screening and
monitoring. Our revenue from our newborn hearing screening product lines may not grow if foreign governments do not require universal
newborn  hearing  screening  prior  to  hospital  discharge,  if  physicians  or  hospitals  are  slow  to  comply  with  those  guidelines,  or  if
governments provide for a lengthy phase-in period for compliance.

Because  we  rely  on  distributors  or  sub-distributors  to  sell  our  products  in  most  of  our  markets  outside  of  the  U.S.,  our  revenue
could  decline  if  our  existing  distributors  reduce  the  volume  of  purchases  from  us,  or  if  our  relationship  with  any  of  these
distributors is terminated

We currently rely on our distributors or sub-distributors for a majority of our sales outside the U.S. Some distributors also assist us
with regulatory approvals and education of clinicians and government agencies. We intend to continue our efforts to increase our sales in
Europe, Japan, and other developed countries. If we fail to sell our products through our international distributors, we would experience a
decline in revenues unless we begin to sell our products directly in those markets. We cannot be certain that we will be able to attract new
international distributors to market our products effectively or provide timely and cost-effective customer support and service. Even if we
are  successful  in  selling  our  products  through  new  distributors,  the  rate  of  growth  of  our  revenue  could  be  harmed  if  our  existing
distributors do not continue to sell a large dollar volume of our products. None of our existing distributors are obligated to continue selling
our products.

We may be subject to foreign laws governing our relationships with our international distributors. These laws may require us to make
payments  to  our  distributors  if  we  terminate  our  relationship  for  any  reason,  including  for  cause.  Some  countries  require  termination
payments under local law or legislation that may supersede our contractual relationship with the distributor. Any required payments would
adversely affect our operating results.

If  we  lose  our  relationship  with  any  supplier  of  key  product  components  or  our  relationship  with  a  supplier  deteriorates  or  key
components are not available in sufficient quantities, our manufacturing could be delayed and our business could suffer

We contract with third parties for the supply of some of the components used in our products and the production of our disposable
products.  Some  of  our  suppliers  are  not  obligated  to  continue  to  supply  us.  We  have  relatively  few  sources  of  supply  for  some  of  the
components  used  in  our  products  and  in  some  cases  we  rely  entirely  on  sole-source  suppliers.  In  addition,  the  lead-time  involved  in  the
manufacturing of some of these components can be lengthy and unpredictable. If our suppliers become unwilling or unable to supply us
with components meeting our requirements, it might be difficult to establish additional or replacement suppliers in a timely manner, or at
all. This would cause our product sales to be disrupted and our revenue and operating results to suffer.

Replacement or alternative sources might not be readily obtainable due to regulatory requirements and other factors applicable to our
manufacturing operations. Incorporation of components from a new supplier into our products may require a new or supplemental filing
with applicable regulatory authorities and clearance or approval of the filing before we could resume product sales. This process may take a
substantial  period  of  time,  and  we  may  not  be  able  to  obtain  the  necessary  regulatory  clearance  or  approval.  This  could  create  supply
disruptions that would harm our product sales and operating results.

We depend upon key employees in a competitive market for skilled personnel, and, without additional employees, we cannot grow
or maintain profitability

Our products and technologies are complex, and we depend substantially on the continued service of our senior management team.

The loss of any of our key employees could adversely affect our business and slow our

27

 
Table of Contents

product  development  process.  Our  future  success  also  will  depend,  in  part,  on  the  continued  service  of  our  key  management  personnel,
software  engineers,  and  other  research  and  development  employees,  and  our  ability  to  identify,  hire,  and  retain  additional  personnel,
including customer service, marketing, and sales staff. Demand for these skilled employees in our industry is very competitive due to the
limited number of people available with the necessary technical skills and understanding of our product technologies. We may be unable to
attract and retain personnel necessary for the development of our business.

Our  ability  to  market  and  sell  products  depends  upon  receipt  of  domestic  and  foreign  regulatory  approval  of  our  products  and
manufacturing  operations.  Our  failure  to  obtain  or  maintain  regulatory  approvals  and  compliance  could  negatively  affect  our
business

Our  products  and  manufacturing  operations  are  subject  to  extensive  regulation  in  the  United  States  by  the  FDA  and  by  similar
regulatory agencies in other countries. Our products are classified as medical devices. Medical devices are subject to extensive regulation
by  the  FDA  pursuant  to  regulations  that  are  wide  ranging  and  govern,  among  other  things:  design  and  development;  manufacturing  and
testing;  labeling;  storage  and  record  keeping;  advertising,  promotion,  marketing,  sales  distribution  and  export;  and  surveillance  and
reporting of deaths or serious injuries.

Unless an exemption applies, each medical device that we propose to market in the U.S. must first receive one of the following types

of FDA premarket review authorizations:

•

•

  Clearance via Section 510(k) of the Food, Drug, and Cosmetics Act of 1938, as amended; or

  Premarket approval via Section 515 of the Food, Drug, and Cosmetics Act if the FDA has determined that the medical device in

question poses a greater risk of injury.

The  FDA  will  clear  marketing  of  a  medical  device  through  the  510(k)  process  if  it  is  demonstrated  that  the  new  product  is
substantially  equivalent  to  other  510(k)-cleared  products.  The  premarket  approval  application  process  is  much  more  costly,  lengthy  and
uncertain than the 510(k) process, and must be supported by extensive data from preclinical studies and human clinical trials. The FDA
may not grant either 510(k) clearance or premarket approval for any product we propose to market. Further, any modification to a 510(k)-
cleared device that could significantly affect its safety or effectiveness, or that would constitute a major change in its intended use, design
or  manufacture,  requires  a  new  510(k)  clearance  or,  possibly,  approval  of  a  premarket  approval  application.  The  FDA  requires  every
manufacturer to make this determination in the first instance, but the FDA may review any manufacturer’s decision. If the FDA requires us
to  seek  510(k)  clearance  or  premarket  approval  for  modification  of  a  previously  cleared  product  for  which  we  have  concluded  that  new
clearances or approvals are unnecessary, we may be required to cease marketing or to recall the modified product until we obtain clearance
or approval, and we may be subject to significant regulatory fines or penalties. Further, our products could be subject to recall if the FDA
determines, for any reason, that our products are not safe or effective.

Delays  in  receipt  of,  or  failure  to  receive,  clearances  or  approvals,  the  loss  of  previously  received  clearances  or  approvals,  or  the
failure to comply with existing or future regulatory requirements could adversely impact our operating results. If the FDA finds that we
have  failed  to  comply  with  these  requirements,  the Agency  can  institute  a  wide  variety  of  enforcement  actions,  ranging  from  a  public
warning letter to more severe sanctions such as:

•

•

•

•

•

•

•

  Fines, injunctions and civil penalties;

  Recall or seizure of our products;

  Issuance of public notices or warnings;

  Imposition of operating restrictions, partial suspension, or total shutdown of production;

  Refusal of our requests for Section 510(k) clearance or premarket approval of new products;

  Withdrawal of Section 510(k) clearance or premarket approvals already granted; or

  Criminal prosecution.

28

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

Domestic regulation of our products and manufacturing operations, other than that which is administered by the FDA, includes the

Environmental Protection Act, the Occupational Safety and Health Act, and state and local counterparts to these Acts.

Our  business  would  be  harmed  if  the  FDA  determines  that  we  have  failed  to  comply  with  applicable  regulations  governing  the
manufacture of our products and/or we do not pass an inspection

We and our suppliers are required to demonstrate and maintain compliance with the FDA’s Quality System Regulation. The Quality
System Regulation sets forth the FDA’s requirements for good manufacturing practices of medical devices and includes requirements for,
among other things, the design, testing, production processes, controls, quality assurance, labeling, packaging, storage and shipping of such
products.  In  addition,  we  and  our  suppliers  must  engage  in  extensive  recordkeeping  and  reporting  and  must  make  available  our
manufacturing  facility  and  records  for  periodic  unscheduled  inspections  by  federal,  state  and  foreign  agencies,  including  the  FDA.  We
cannot assure you that we and our suppliers are or will continue to be in full compliance with the Quality System Regulation, and that we
will not encounter any manufacturing difficulties.

Failure  of  our  third  party  suppliers  and  manufacturers  or  us  to  comply  with  applicable  regulations  could  result  in  sanctions  being
imposed  on  us,  including,  among  other  things,  fines,  injunctions,  civil  penalties,  failure  of  regulatory  authorities  to  grant  marketing
approval of our products, delays, suspension or withdrawal of approvals, seizures or recalls of products and manufacturing restrictions, any
of which could harm our business.

Our Olympic Cool-Cap product is subject to greater products liability exposure and FDA regulation

The FDA classifies medical devices into one of three classes depending on the degree of risk associated with each medical device and
the extent of controls that are needed to ensure safety and effectiveness. Devices deemed to pose lower risk are placed in either Class I or
Class II. Devices deemed by the FDA to pose the greatest risk, such as life-sustaining, life supporting or implantable devices, or a device
deemed  to  not  be  substantially  equivalent  to  a  previously  cleared  510(k)  device  are  placed  in  class  III,  and  generally  require  premarket
approval from the FDA before they may be marketed.

Our  Olympic  Cool-Cap  is  a  Class  III  minimally  invasive  medical  device,  and  as  such  we  may  be  subject  to  an  increased  product
liability  risk  relative  to  our  other  Class  I  and  Class  II  non-invasive  products.  In  addition,  this  type  of  product  is  subject  to  greater  FDA
oversight  than  our  other  products  and  there  is  greater  risk  that  sales  of  the  product  could  be  interrupted  due  to  the  premarket  approval
processes of the FDA and other regulatory bodies.

Our business may suffer if we are required to revise our labeling or promotional materials, or if the FDA takes an enforcement
action against us for off-label uses

We  are  prohibited  by  the  FDA  from  promoting  or  advertising  our  medical  device  products  for  uses  not  within  the  scope  of  our
clearances or approvals, or from making unsupported promotional claims about the benefits of our products. If the FDA determines that our
claims are outside the scope of our clearances, or are unsupported, it could require us to revise our promotional claims or take enforcement
action  against  us.  If  we  were  subject  to  such  an  action  by  the  FDA,  our  sales  could  be  delayed,  our  revenue  could  decline,  and  our
reputation among clinicians could be harmed. Likewise, if we acquire new products, either through the purchase of products, technology
assets,  or  businesses,  that  are  subsequently  deemed  to  have  inadequate  supporting  data,  we  may  be  required  to  (i)  obtain  adequate  data,
which could be costly and impede our ability to market these products, or (ii) modify the labeling on these products, which could impair
their marketability, as described above.

If we deliver products with defects, we may incur costs to repair and, possibly, recall that product and market acceptance of our
products may decrease.

The manufacturing and marketing of our products involve an inherent risk of our delivering a defective product or products that do

not otherwise perform as we expect. We may incur substantial expense to repair any

29

 
Table of Contents

such products and may determine to recall such a product, even if not required to do so under applicable regulations. Any such recall would
be time consuming and expensive. Product defects or recalls may adversely affect our customers’ acceptance of the recalled and other of
our  products. As  an  example,  in  the  second  quarter  of  2010  we  discontinued  selling  the  Sonamed  Clarity  newborn  hearing  screening
product line and incurred costs associated with sales concessions awarded customers who traded in a Clarity device for one of our existing
newborn  hearing  screening  devices  and  the  write-down  of  inventory.  We  also  recorded  an  impairment  charge  to  write-off  the  carrying
value of the Sonamed and Clarity tradenames.

If  we  fail  to  comply  with  healthcare  regulations,  we  could  face  substantial  penalties  and  our  business,  operations  and  financial
condition could be adversely affected.

We do not provide healthcare services, control the referral of patients for healthcare services, nor bill Medicare, Medicaid or other
third-party payors; however, due to the breadth of many healthcare laws and regulations, we could be subject to healthcare fraud regulation
and enforcement by both the federal government and the states in which we conduct our business. The laws that may affect our ability to
operate include: (i) the federal healthcare programs Anti-Kickback Law, which prohibits, among other things, persons from knowingly and
willfully soliciting, receiving, offering or paying remuneration, directly or indirectly, in exchange for or to induce either the referral of an
individual for, or the purchase, order or recommendation of, any good or service for which payment may be made under federal healthcare
programs  such  as  Medicare  or  Medicaid,  (ii)  federal  false  claims  laws  which  prohibit,  among  other  things,  individuals  or  entities  from
knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid, or other third-party payors that are false or
fraudulent, and which may apply to entities like us which provide coding and billing advice to customers, and/or (iii) state law equivalents
of each of the above federal laws, such as anti-kickback and false claims laws which may apply to items or services reimbursed by any
third-party  payor,  including  commercial  insurers,  many  of  which  differ  from  their  federal  counterparts  in  significant  ways,  thus
complicating compliance efforts.

If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to
us,  we  may  be  subject  to  penalties,  including  civil  and  criminal  penalties,  damages,  fines  and  the  curtailment  or  restructuring  of  our
operations. Any penalties, damages, fines, curtailment or restructuring of our operations could adversely affect our ability to operate our
business and our financial results. The risk of our being found in violation of these laws is increased by the fact that their provisions are
open to a variety of interpretations. Any action against us for violation of these laws, even if we successfully defend against it, could cause
us to incur significant legal expenses and divert our management’s attention from the operation of our business.

Our operating results would suffer if we were subject to a protracted infringement claim

The  medical  technology  industry  is  characterized  by  a  substantial  amount  of  litigation  and  related  administrative  proceedings
regarding  patents  and  intellectual  property  rights.  We  expect  that  medical  screening  and  diagnostic  products  may  become  increasingly
subject to third-party infringement claims as the number of competitors in our industry grows and the functionality of products overlap.
Third parties such as individuals, educational institutions, or other medical device companies may claim that we infringe their intellectual
property rights. Any claims, with or without merit, could have any of the following negative consequences:

•

•

•

•

  Result in costly litigation and damage awards;

  Divert our management’s attention and resources;

  Cause product shipment delays or suspensions; or

  Require us to seek to enter into royalty or licensing agreements.

A successful claim of infringement against us could result in a substantial damage award and materially harm our financial condition.
Our failure or inability to license the infringed or similar technology, or design and build non-infringing products, could prevent us from
selling our products and adversely affect our business and financial results.

30

 
 
 
 
 
 
 
 
 
Table of Contents

We  may  also  find  it  necessary  to  bring  infringement  actions  against  third  parties  to  seek  to  protect  our  intellectual  property  rights.
Litigation of this nature, even if successful, is often expensive and disruptive of our management’s attention, and in any event may not lead
to a successful result relative to the resources dedicated to any such litigation.

We  license  intellectual  property  rights  from  third  parties  and  would  be  adversely  affected  if  our  licensors  do  not  appropriately
defend their proprietary rights or if we breach any of the agreements under which we license commercialization rights to products
or technology from others

We license rights from third parties for products and technology that are important to our business. If our licensors are unsuccessful in
asserting and defending their proprietary rights, including patent rights and trade secrets, we may lose the competitive advantages we have
through selling products that we license from third parties. Additionally, if it is found that our licensors infringe on the proprietary rights of
others,  we  may  be  prohibited  from  marketing  our  existing  products  that  incorporate  those  proprietary  rights.  Under  our  licenses,  we  are
subject to commercialization and development, sublicensing, royalty, insurance and other obligations. If we fail to comply with any of these
requirements, or otherwise breach a license agreement, the licensor may have the right to terminate the license in whole or to terminate the
exclusive nature of the license.

Product liability suits against us could result in expensive and time consuming litigation, payment of substantial damages, and an
increase in our insurance rates

The sale and use of our products could lead to the filing of a product liability claim by someone claiming to have been injured using
one of our products or claiming that one of our products failed to perform properly. A product liability claim could result in substantial
damages and be costly and time consuming to defend, either of which could materially harm our business reputation or financial condition.
Our  product  liability  insurance  may  not  protect  our  assets  from  the  financial  impact  of  defending  a  product  liability  claim. Any  product
liability claim brought against us, with or without merit, could increase our product liability insurance rates or prevent us from securing any
coverage in the future.

We have experienced seasonality in the sale of our products

We experience seasonality in our revenue. For example, our sales typically decline from our fourth fiscal quarter to our first fiscal
quarter, due to patterns in the capital budgeting and purchasing cycles of our customers, many of which are government agencies, and the
compensation  arrangements  of  our  direct  sales  employees,  as  those  arrangements  are  tied  to  calendar-year  sales  plans.  We  may  also
experience declining sales in the third fiscal quarter due to summer holiday and vacation schedules. We anticipate that we will continue to
experience these seasonal fluctuations, which may lead to fluctuations in our quarterly operating results. We believe that you should not
rely on our results of operations for interim periods as an indication of our expected results in any future period.

Business

Natus is a leading provider of healthcare products used for the screening, detection, treatment, monitoring and tracking of common
medical  ailments  in  newborn  care,  hearing  impairment,  neurological  dysfunction,  epilepsy,  sleep  disorders,  and  balance  and  mobility
disorders. Product offerings include computerized neurodiagnostic systems for audiology, neurology, polysomnography, and neonatalogy,
as well as newborn care products such as hearing screening systems, phototherapy devices for the treatment of newborn jaundice, head-
cooling products for the treatment of brain injury in newborns, incubators to control the newborn’s environment, and software systems for
managing and tracking disorders and diseases for public health laboratories.

We  have  completed  a  number  of  acquisitions  since  2003,  consisting  of  either  the  purchase  of  a  company,  substantially  all  of  the
assets of a company, or individual products or product lines. Our significant acquisitions are as follows: Neometrics in 2003, Fischer-Zoth
in  2004,  Bio-logic,  Deltamed,  and  Olympic  in  2006,  Xltek  in  2007,  Sonamed,  Schwarzer  Neurology,  and  Neurocom  in  2008,  Hawaii
Medical and Alpine Biomed in 2009, and Medix in 2010.

Year 2010 Overview

We faced an uncertain business in 2010 as the global economy continued its recovery from the recessionary economic conditions that
existed in many parts of the world during 2008 and 2009, particularly in North America and Europe where we conduct the majority of our
business.

Our consolidated revenue increased $52.2 million for the year ended December 31, 2010 compared to 2009, primarily as a result of
improved economic conditions. Revenue increased across all of our business units. Alpine Biomed and Hawaii Medical, that we acquired in
2009, contributed to $22.7 of incremental revenue in 2010, while Medix, that was acquired in 2010, contributed to $7.1 of revenue in 2010.

36

 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

During  the  second  fiscal  quarter  of  2010  we  substantially  completed  the  reorganization  plan  adopted  in  January  2010  that  was
designed to eliminate redundant costs resulting from our acquisition of Alpine Biomed and to improve efficiencies in operations. Under the
plan, Alpine operations in Montreal, Canada were transitioned to our existing Xltek facility in Oakville, Ontario, Canada. Alpine’s sales
organization was merged into the Company’s global sales organization during the first fiscal quarter of 2010.

Also in the second fiscal quarter of 2010 we discontinued the Sonamed Clarity hearing screening product line and began converting
users  to  our  other  newborn  hearing  screening  products.  This  action  resulted  in  a  non-recurring  charge  totaling  $1.4  million  that  reduced
reported  gross  profit  by  $1.1  million  or  0.8  percentage  points  and  increased  operating  expenses  by  $300,000.  The  conversion  was
substantially complete as of December 31, 2010.

During the third quarter of 2010 we received a purchase order from the Kingdom of Saudi Arabia for our newborn care products. The
order,  valued  at  over  $2.9  million,  was  for  our ALGO  newborn  hearing  screeners,  Cool-Cap  selective  head-cooling  devices,  Olympic
Cerebral Functions Monitors (CFM), and associated disposable supplies. We completed the shipment of this purchase order in the fourth
quarter.

We acquired Medix in October 2010 for $14.1 million in cash. Medix, based in Buenos Aires, Argentina, manufactures incubators for
use in hospital nurseries and NICU’s, transport incubators for use in ambulances and other emergency vehicles, infant warmers, and LED-
based phototherapy devices.

We do not believe that our markets have yet returned to the level of activity that prevailed prior to the commencement of the credit
crisis in the third quarter of 2008 that precipitated the global economic crisis. As a result of cost containment and other measures we have
implemented, and our recent acquisitions, we believe that we continue to be well-positioned to capitalize on improving market conditions
as, and to the extent, that such conditions develop.

Application of Critical Accounting Policies

We  prepare  our  financial  statements  in  accordance  with  accounting  principles  generally  accepted  in  the  United  States  of America
(“GAAP”).  In  so  doing,  we  must  often  make  estimates  and  use  assumptions  that  can  be  subjective  and,  consequently,  our  actual  results
could  differ  from  those  estimates.  For  any  given  individual  estimate  or  assumption  we  make,  there  may  also  be  other  estimates  or
assumptions that are reasonable.

We believe that the following critical accounting policies require the use of significant estimates, assumptions, and judgments. The
use of different estimates, assumptions, and judgments could have a material effect on the reported amounts of assets, liabilities, revenue,
expenses, and related disclosures as of the date of the financial statements and during the reporting period.

Revenue recognition

Revenue,  net  of  discounts,  is  recognized  from  sales  of  medical  devices  and  supplies,  including  sales  to  distributors,  when  the
following conditions have been met: a purchase order has been received, title has transferred, the selling price is fixed or determinable, and
collection of the resulting receivable is reasonably assured. Terms of sale for most domestic sales are FOB origin, reflecting that title and
risk  of  loss  are  assumed  by  the  purchaser  at  the  shipping  point;  however,  terms  of  sale  for  some  neurology,  sleep-diagnostic,  and  head
cooling systems are FOB destination, reflecting that title and risk of loss are assumed by the purchaser upon delivery. Terms of sales to
international distributors are generally EXW, reflecting that goods are shipped “ex works,” in which title and risk of loss are assumed by
the distributor at the shipping point.

We  have  historically  applied  the  software  revenue  recognition  rules  as  prescribed  by Accounting  Standards  Codification  (“ASC”)
Subtopic  985-605  to  sales  of  certain  of  our  diagnostic  neurology  and  hearing  systems  (“products  containing  embedded  software”).  In
October 2009, the Financial Accounting Standards Board

37

 
Table of Contents

(“FASB”)  issued Accounting  Standards  Update  No.  (“ASU”)  2009-14,  Certain Revenue Arrangements That Include Software Elements ,
which  amended ASC  Subtopic  985-605,  and  we  prospectively  adopted  the  provisions  of ASU  2009-14  on  January  1,  2010.  This ASU
removes  tangible  products  containing  software  components  and  non-software  components  that  function  together  to  deliver  the  product’s
essential  functionality  from  the  scope  of  the  software  revenue  recognition  rules.  In  the  case  of  the  Company’s  products  containing
embedded software, we have determined that the hardware and software components function together  to  deliver  the  products’  essential
functionality, and therefore, the revenue from the sale of these products no longer falls within the scope of the software revenue recognition
rules. Our revenue recognition policies for sales of these products are now substantially the same as for our other tangible products.

Revenue  from  sales  of  certain  of  our  products  that  remain  within  the  scope  of  the  software  revenue  recognition  rules  under ASC

Subtopic 985-605 is not significant.

We  previously  accounted  for  arrangements  with  multiple  deliverables  under ASC  Topic  605,  where  revenue  was  allocated  to  the
deliverables based on vendor specific objective evidence (“VSOE”). In October 2009 the FASB issued ASU 2009-13,  Multiple Deliverable
Revenue Arrangements, which amends ASC Topic 605, and we prospectively adopted the provisions of ASU 2009-13 on January 1, 2010.
Under the revenue recognition rules for tangible products as amended by ASU 2009-13, we now allocate revenue from arrangements with
multiple  deliverables  to  each  of  the  deliverables  based  upon  their  relative  selling  prices  as  determined  by  a  selling-price  hierarchy. A
deliverable in an arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a stand-alone
basis. The principal deliverables in our multiple deliverable arrangements that qualify as separate units of accounting consist of (i) sales of
medical devices and supplies, (ii) installation services, (iii) extended service and maintenance agreements, and (iv) upgrades to embedded
software.

The  new  rules  establish  a  hierarchy  to  determine  the  selling  price  to  be  used  for  allocating  revenue  to  deliverables  as  follows:
(i) vendor-specific objective evidence of fair value (“VSOE”), (ii) third-party evidence of selling price (“TPE”), and (iii) best estimate of
the selling price (“ESP”). VSOE of fair value is defined as the price charged when the same element is sold separately, or if the element
has not yet been sold separately, the price for the element established by management having the relevant authority when it is probable that
the  price  will  not  change  before  the  introduction  of  the  element  into  the  marketplace.  VSOE  generally  exists  only  when  we  sell  the
deliverable separately and is the price actually charged for that deliverable. We have previously established VSOE for substantially all of
the deliverables in our multiple element arrangements; however, in the future we may rely on ESPs, reflecting our best estimates of what
the selling prices of elements would be if they were sold regularly on a stand-alone basis, to establish the amount of revenue to allocate to
the deliverable. TPE generally does not exist for our products because of their uniqueness.

For products shipped under FOB origin or EXW terms, delivery is generally considered to have occurred when shipped. Undelivered
elements in our sales arrangements, which are not considered to be essential to the functionality of a product, generally include installation
or training services that are performed after the related products have been delivered. Revenue related to undelivered installation services is
deferred  until  such  time  as  installation  is  complete  at  the  customer’s  site.  Revenue  related  to  training  services  is  recognized  when  the
service is provided. Fair value for installation or training services is based on the price charged when the service is sold separately. The fair
value of installation and training services is based upon billable hourly rates and the estimated time to complete the service.

Revenue from extended service and maintenance agreements, for both medical devices and data management systems, is recognized
ratably over the service period. Freight charges billed to customers are included in revenue and freight-related expenses are charged to cost
of revenue. Advance payments from customers are recorded as deferred revenue and recognized as revenue as otherwise described above.
We generally do not provide rights of return on products. We accept trade-ins of our own and competitive medical devices. Trade-ins are
recorded  as  a  reduction  of  the  replacement  medical  device  sale.  Provisions  are  made  for  initial  standard  warranty  obligations  that  are
generally one year in length.

Inventory is carried at the lower of cost or market value

We may be exposed to a number of factors that could result in portions of our inventory becoming either obsolete or being held in
quantities that exceed anticipated usage. These factors include, but are not limited to: technological changes in our markets, competitive
pressures in products and prices, and our own introduction of new product lines.

We regularly evaluate our ability to realize the value of our inventory based on a combination of factors, including historical usage
rates, forecasted sales, product life cycles, and market acceptance of new products. When we identify inventory that is obsolete or in excess
of anticipated usage we write it down to realizable salvage value. The estimates we use in projecting future product demand may prove to
be incorrect. Any future determination that our inventory is overvalued could result in increases to our cost of sales and decreases to our
operating margins and results of operations.

Carrying value of intangible assets and goodwill

We amortize intangible assets with finite lives over their useful lives; any future changes that would limit their useful lives or any
determination that these assets are carried at amounts greater than their estimated fair value could result in additional charges. We carry
goodwill and any other intangible assets with indefinite lives at original cost but do not amortize them. Any future determination that these
assets are carried at amounts greater than their estimated fair value could result in additional charges, which could significantly impact our
operating results.

We test our definite-lived intangible assets for impairment whenever changes in circumstances indicate  the  carrying  value  of  these
assets  may  be  impaired.  Impairment  indicators  include,  but  are  not  limited  to,  net  book  value  as  compared  to  market  capitalization,
significant  negative  industry  and  economic  trends,  and  significant  underperformance  relative  to  historical  and  projected  future  operating
results. Impairment is considered to have occurred when the estimated undiscounted future cash flows related to the asset are less than its
carrying value. Estimates of future cash flows involve consideration of many factors including the marketability of new products, product
acceptance and lifecycle, competition, appropriate discount rates, and operating margins.

Goodwill and indefinite-lived intangible assets are tested for impairment at least annually as of October 1st; this assessment is also
performed  whenever  there  is  a  change  in  circumstances  that  indicates  the  carrying  value  of  these  assets  may  be  impaired.  The
determination of whether any potential impairment of goodwill exists is based upon a two step process. In the first analysis, the fair value
of the reporting unit is compared to the unit’s fair value, including goodwill, to determine if there is a potential impairment. If the fair value
exceeds the carrying amount, the goodwill of the reporting unit is considered not impaired and no further analysis or action is required. If
the  first  analysis  indicates  that  the  carrying  value  exceeds  the  fair  value,  a  second  analysis  is  performed  to  determine  the  amount  of  the
goodwill impairment loss, if any.

In step two of the impairment test, the implied fair value of a reporting unit’s goodwill is compared to the carrying amount of that
goodwill.  The  implied  fair  value  of  the  goodwill  shall  be  determined  in  the  same  manner  as  the  amount  of  goodwill  recognized  in  a
business combination is determined. That is, the entity shall allocate the fair value of a reporting unit to all the assets and liabilities of that
reporting unit, including unrecognized intangible assets as if the reporting unit had been acquired in a business combination and the fair
value  of  the  reporting  unit  was  the  price  paid  to  acquire  the  reporting  unit.  The  excess  of  the  fair  value  of  the  reporting  unit  over  the
amounts assigned to its assets and liabilities is the implied fair value of that goodwill.

To determine the estimated fair value of reporting units, three valuation methodologies are utilized: (i) discounted cash flow analyses,
(ii)  market  multiples,  and  (iii)  comparative  transactions.  The  valuations  indicated  by  these  three  methodologies  are  averaged,  with  the
greatest weight placed on discounted cash flow analyses. Discounted cash flow analyses are dependent upon a number of quantitative and
qualitative  factors  including  estimates  of  forecasted  revenue,  profitability,  earnings  before  interest,  taxes,  depreciation  and  amortization
(i.e. EBITDA) and terminal values. The discount rates applied in the discounted cash flow analyses also have an impact on the estimates of
fair value, as use of a higher rate will result in a lower estimate of fair value. The estimated total fair value of reporting units is reconciled
to the Company’s market capitalization.

Liability for product warranties

Our  medical  device  products  are  covered  by  standard  one-year  product  warranty  plans.  A  liability  has  been  established  for  the
expected cost of servicing our medical device products during these service periods. We base the liability on actual warranty costs incurred
to  service  those  products.  On  new  products,  additions  to  the  reserve  are  based  on  a  combination  of  factors  including  the  percentage  of
service department labor applied to warranty repairs, as well as actual service department costs and other judgments, such as the degree to
which the product incorporates new technology applied to the number of units sold. As warranty costs are incurred, the reserve is reduced.

The  estimates  we  use  in  projecting  future  product  warranty  costs  may  prove  to  be  incorrect. Any  future  determination  that  our
product warranty reserves are understated could result in increases to our cost of sales and reductions in our operating profits and results of
operations.

Share-based compensation

We  record  the  fair  value  of  share-based  compensation  awards  as  expenses  in  the  consolidated  statement  of  operations.  In  order  to
determine the fair value of stock options on the date of grant, we apply the Black-Scholes option-pricing model. Inherent in this model are
assumptions  related  to  expected  dividend  yield,  risk-free  interest  rate,  expected  stock-price  volatility,  expected  term,  and  forfeiture  rate.
While  the  risk-free  interest  rate  and  dividend  yield  are  less  subjective  assumptions,  typically  based  on  factual  data  derived  from  public
sources, expected stock-price volatility, expected life, and forfeiture rate assumptions require a greater level of judgment which makes them
critical accounting estimates. If we used different assumptions, we would have recorded different amounts of share-based compensation.

Acquisitions

We  completed  six  significant  acquisitions  during  2010,  2009  and  2008,  and  the  timing  of  these  acquisitions  had  an  impact  on  the

comparison of our results of operations for the years ended December 31, 2010, 2009 and 2008.

•

•

•

•

•

•

  Medix—Completed on October 12, 2010. Medix reported revenue of approximately $25.2 million during its last completed fiscal

year prior to the acquisition.

  Alpine  Biomed—Completed  on  September  14,  2009.  Alpine  Biomed  reported  revenue  from  its  neurology  business  of

approximately $38.1 million during its last completed fiscal year prior to the acquisition.

  Hawaii Medical—Completed  on  July  2,  2009.  Hawaii  Medical  reported  revenue  of  approximately  $3.2  million  during  its  last

completed fiscal year prior to the acquisition.

  Neurocom—Completed  on  October  2,  2008.  Neurocom  reported  revenue  of  approximately  $11.4  million  during  its  last

completed fiscal year prior to the acquisition.

  Schwarzer  Neurology—Completed  on  July  2,  2008.  Schwarzer  Neurology  reported  revenue  of  approximately  $7.1  million

during its last completed fiscal year prior to the acquisition.

  Sonamed—Completed  on  May  27,  2008.  Sonamed  reported  revenue  of  approximately  $3.5  million  during  its  last  completed

fiscal year prior to the acquisition.

The pre-acquisition revenue of our acquired companies may not be indicative of their contribution to revenue in the future.

Comparison of 2010 and 2009

Operating Results

Because our acquisitions have been significant, we measure the contribution to consolidated revenue  of  the  businesses  we  acquire.
We  also  analyze  our  revenue  as  coming  from  two  sources:  devices  and  systems,  and  supplies  and  services.  We  report  freight  revenue
separate from these two sources.

Our consolidated revenue increased $52.2 million for the year ended December 31, 2010 compared to 2009, primarily as a result of
improved  economic  conditions.  Revenue  increased  across  all  of  our  business  units.  The  companies  that  were  acquired  in  2009, Alpine
Biomed and Hawaii Medical, contributed to $22.7 of incremental revenue in 2010, while Medix, that was acquired in 2010, contributed to
$7.1 million of revenue in 2010. Revenue from our hearing products increased $3.4 million, while revenue from our existing neurology and
newborn care products increased by $19.0 million.

Revenue from devices and systems was $134.8 million in 2010, representing an increase of 40% or $38.6 million, from $96.2 million
reported  in  2009.  Alpine  Biomed  contributed  to  $13.0  million  of  incremental  devices  and  systems  revenue  in  2010,  while  Medix
contributed to $4.1 million of devices and systems revenue in 2010. Revenue from our hearing products increased $5.1 million, to $30.3
million,  while  revenue  from  our  existing  neurology  and  newborn  care  products  increased  by  $17.8  million  to  $62.1  million,  offset  by  a
$1.4 million decrease in balance monitoring products.

Revenue from supplies and services was $80.3 million in 2010, representing an increase of 20%, or $13.2 million from $67.1 million
in 2009. Alpine Biomed, Medix and Hawaii Medical contributed to $6.8 million, $3.0 million and $2.7 million, respectively, of incremental
revenue from supplies and services. Supplies and service revenue from our existing products increased by $700,000 to $67.8 million.

Revenue from devices and systems was 62% of consolidated revenue in 2010 compared to 58% of total revenue in 2009, and revenue
from supplies and services was 37% of total revenue in 2010 compared to 40% of revenue in 2009. Freight revenue of $3.6 million in 2010
and $3.2 million in 2009 represented 1% and 2% of total revenue in 2010 and 2009, respectively.

No customer accounted for more than 10% of our revenue in either 2010 or 2009. Revenue from domestic sales increased 15% to
$126.9 million in 2010, from $109.7 million in 2009. Revenue from international sales increased 62% to $91.8 million in 2010, compared
to $56.8 million in 2009. Revenue from domestic sales was 58% of total revenue in 2010, compared to 66% in 2009, and revenue from
international sales was 42% of total revenue in 2010 compared to 34% of revenue in 2009. The changes in the percentages from 2010 to
2009 resulted primarily from the contribution of Alpine Biomed and Medix, whose sales are primarily in Europe and South America and
related international markets, respectively.

Our cost of revenue increased $22.6 million, or 34%,  to  $88.7  million  in  2010,  from  $66.1  million  in  2009.  The  increase  was  due
mainly  to  our  increased  sales.  In  addition,  our  discontinuance  of  the  Sonamed  Clarity  hearing  screening  line  resulted  in  a  non-recurring
charge totaling $1.1 million or 1.2% to our cost of revenue. Gross profit increased $29.6 million, or 30%, to $130.0 million in 2010 from
$100.3 million in 2009. Gross profit as a percentage of revenue was 59% in 2010 compared with 60% in 2009.

Total  operating  costs  increased  $27.1  million,  or  32%,  to  $112.1  million  in  2010,  from  $85.0  million  in  2009.  The  operations  of
Alpine Biomed and Medix contributed to $11.7 million of the increase in operating costs. We also recorded a restructuring charge of $3.1
million and other severance related costs of $842,000 for which there was no comparable cost in 2009. The remainder of the increase in
operating costs was proportionate to our increased sales as our operating costs as a percentage of revenue was 51% in 2010 and 2009.

Our  marketing  and  selling  expenses  increased  $9.6  million,  or  21%,  to  $54.9  million  in  2010,  from  $45.3  million  in  2009.  The
operations of Alpine Biomed and Medix contributed to $5.0 million of the increase and the remainder of the increase was primarily related
to higher sales commission and sales related costs associated with the increase in our revenue. Marketing and selling expenses as a percent
of total revenue decreased to 25.1 % in 2010 from 27.2% in 2009.

Our research and development expenses increased $4.6 million, or 27%, to $21.3 million in 2010 from $16.7 million in 2009. The
operations  of Alpine  Biomed  and  Medix  contributed  to  $3.1  million  of  research  and  development  expense.  Research  and  development
expenses as a percent of total revenue decreased to 9.7% in 2010 from 10.0% in 2009.

Our  general  and  administrative  expenses  increased  $13.0  million,  or  57%,  to  $36.0  million  in  2009  from  $23.0  million  in  2009.
General and administrative expenses as a percent of revenue increased from 13.8% in 2009 to 16.5% in 2010. $3.5 million of the increase in
general and administrative expenses was attributable to the operations of Alpine Biomed and Medix. We recorded a restructuring charge of
$3.1 million and other severance related costs of $842,000 for which there were no comparable costs in 2009. Other expenses exclusive of
those associated with Alpine Biomed, Medix, restructuring and severance related costs were $5.6 million higher in 2010 compared to 2009,
which resulted primarily from increased payroll and related benefit costs, professional fees, travel and outside consulting costs.

Other  income  (expense),  net  consists  of  investment  income,  interest  expense,  net  currency  exchange  gains  and  losses,  and  other
miscellaneous  income  and  expense.  We  reported  other  income  (expense),  net  of  $(118,000)  in  2010,  compared  to  $1.7  million  in  2009.
Investment income of $36,000 in 2010 was $192,000 less than the amount reported for 2009 reflecting lower interest rates. We reported
$521,000 of foreign currency exchange losses in 2010 versus $520,000 of foreign exchange gains in 2009. Interest expense was marginally
lower in 2010 compared to 2009 due primarily to lower outstanding balances on our credit facilities.

We recorded income tax expense of $5.8 million in 2010, compared to $5.7 million recorded in 2009. Our effective tax rate for 2010
decreased to 32.7 % from 33.4% in 2009 because more of our income was taxed in foreign jurisdictions with tax rates lower than in the
U.S. At December 31, 2010, we had federal net operating loss carryforwards of approximately $4.6 million available to offset future taxable
income. Income tax expense related to our international operations is based on the statutory rates in those jurisdictions.

Comparison of 2009 and 2008

Operating Results

Our revenue increased 3%, or $4.6 million, to $166.4 million in 2009, from $161.8 million in 2008. Alpine Biomed, Neurocom and
Schwarzer Neurology contributed $17.4 million to this increase in our revenue in 2009. This was offset by a $12.2 million net decrease in
equipment sales across the Company’s other product lines, resulting from a weakness in demand that we believe was due to the economic
recession during 2009.

Revenue from devices and systems was $96.2 million in 2009, representing a decrease of 6% or $6.3 million, from $102.5 million
reported in 2008. The operations of Alpine Biomed, Neurocom and Schwarzer Neurology contributed to $12.1 million of the increase in
revenue from devices and systems offset by a $6.8 million decrease in hearing revenue, a $5.3 million decrease in neurology revenue, and a
$3.1 million decrease in newborn care revenue. Revenue from supplies and services was $67.1 million in 2009, representing an increase of
18%, or $10.4 million, from $56.7 million in 2008. The operations of Alpine Biomed, Neurocom and Schwarzer Neurology contributed to
$5.1 million of the increase. Hearing supplies increased by $1.3 million and newborn care supplies increased by $2.0 million.

Revenue from devices and systems was 58% of consolidated revenue in 2009 compared to 63% of total revenue in 2008, and revenue
from supplies and services was 40% of total revenue in 2009 compared to 35% of revenue in 2008. Freight revenue of $3.2 million in 2009
and $2.7 million in 2008 represented 2% of total revenue in both periods.

No  customer  accounted  for  more  than  10%  of  our  revenue  in  either  2009  or  2008.  Revenue  from  domestic  sales  decreased  3%  to
$109.7 million in 2009, from $112.6 million in 2008. Revenue from international sales increased 15% to $56.8 million in 2009, compared
to $49.2 million in 2008. Revenue from domestic sales was 66% of total revenue in 2009, compared to 70% in 2008, and revenue from
international sales was 34% of total revenue in 2009 compared to 30% of revenue in 2008. The changes in the percentages from 2009 to
2008 resulted primarily from the contribution of Alpine Biomed, whose sales are primarily in Europe.

Our cost of revenue increased $4.7 million, or 8%, to $66.1 million in 2009, from $61.3 million in 2008. The increase was primarily
due to our increased sales and higher materials costs. Gross profit decreased $151,000, or less than half a percent to $100.3 million in 2009
from $100.5 million in 2008. Gross profit as a percentage of revenue was 60% in 2009 compared to 62% in 2008. The decline in gross
profit as a percentage of sales was due in part to the Alpine Biomed products having a lower gross margin than our existing products. In
addition,  the  gross  profit  percentage  of  our  European  operations,  excluding  Alpine,  was  approximately  50%  for  2009  compared  to
approximately  59%  for  2008,  due  primarily  to  the  impact  that  a  lower  revenue  base  had  on  manufacturing  overhead  as  a  percentage  of
revenue, as this cost is largely fixed.

Total operating costs increased $9.7 million, or 13%, to $85.0 million in 2009, from $75.3 million in 2008. The operations of Alpine
Biomed,  Neurocom  and  Schwarzer  Neurology  contributed  to  $12.5  million  of  the  increase  in  operating  costs  partially  offset  by  a  $2.8
million decrease in operating costs in our North American divisions resulting from restructuring activities initiated in early 2008 that were
substantially completed in that year. Our operating costs increased as a percentage of revenue from 47% in 2008 to 51% in 2009.

Our  marketing  and  selling  expenses  increased  $5.3  million,  or  13%,  to  $45.3  million  in  2009,  from  $40.0  million  in  2008.  The
operations of Alpine Biomed, Neurocom, and Schwarzer Neurology contributed to $6.7 million of the increase offset by a decrease of $1.2
million in sales compensation costs resulting from decreased direct sales of devices. Marketing and selling expenses as a percent of total
revenue increased from 24.7% in 2008 to 27.2% in 2009.

Our  research  and  development  expenses  increased  $1.2  million,  or  8%,  to  $16.7  million  in  2008  from  $15.5  million  in  2008.  The

operations of Alpine Biomed, Neurocom, and Schwarzer Neurology contributed to

43

 
Table of Contents

$2.2 million of research and development expense, partially offset by reduced costs resulting from restructuring activities implemented in
February 2008 for which we did not receive a benefit until late in 2008 and continuing into 2009. Research and development expenses as a
percent of total revenue increased from 9.6% in 2008 to 10.0% in 2009.

Our general and administrative expenses increased $3.2 million, or 16%, to $23.0 million in 2009 from $19.8 million in 2008. General
and administrative expenses as a percent of revenue increased from 12.2% in 2008 to 13.8% in 2009. General and administrative expenses
of Alpine Biomed, Neurocom and Schwarzer Neurology represented $3.6 million of the increase. Direct costs of acquisitions completed in
2009 totaled $460,000 and were reported as a component of general and administrative expense; we had no similar costs in 2008 under prior
accounting  rules.  General  and  administrative  expenses  other  than  those  mentioned  above  were  approximately  $560,000  lower  in  2009
compared to 2008.

Other income, net consists of investment income, interest expense, net currency exchange gains and losses, and other miscellaneous
income  and  expense.  We  reported  other  income,  net  of  $1.7  million  in  2009,  compared  to  $2.1  million  in  2008.  Investment  income  of
$228,000 in 2009 was $801,000 less than the amount reported for 2008 reflecting lower interest rates and a lower investment portfolio due
to our recent acquisitions. Net foreign currency exchange gains reported in 2009 were $1.1 million less than the amount reported for 2008.
We  reported  $582,000  less  in  interest  expense  in  2009  compared  to  2008  due  primarily  to  lower  outstanding  balances  on  our  credit
facilities. In 2009 we also recorded a $650,000 adjustment to the value of a contingent liability associated with the acquisition of Alpine
Biomed that resulted in an increase to other income for which there was no similar item in 2008.

We recorded income tax expense of $5.7 million in 2009, compared to $10.0 million recorded in 2008. Our effective tax rate for 2009
decreased to 33.4% compared to 36.7% in 2008 because more of our income was taxed in foreign jurisdictions with tax rates lower than in
the U.S. At December 31, 2009, we had federal net operating loss carryforwards of approximately $8.2 million available to offset future
taxable income. Income tax expense related to our international operations is based on the statutory rates in those jurisdictions.

Liquidity and Capital Resources

Comparison of 2010 and 2009

Liquidity  is  our  ability  to  generate  sufficient  cash  flows  from  operating  activities  to  meet  our  obligations  and  commitments.  In
addition,  liquidity  includes  the  ability  to  obtain  appropriate  financing  and  to  raise  capital.  Therefore,  liquidity  cannot  be  considered
separately from capital resources that consist of our current funds and the potential to increase those funds in the future. We plan to use
these resources in meeting our commitments and in achieving our business objectives.

As of December 31, 2010, we had cash, cash equivalents, and short-term investments of $29.4 million, stockholders’ equity of $263.3
million, and working capital of $83.9 million, compared with cash and cash equivalents of $33.6 million, stockholders’ equity of $243.6
million, and working capital of $75.2 million as of December 31, 2009.

We believe that our current cash and cash equivalents and any cash generated from operations will be sufficient to meet our ongoing
operating and capital requirements for the foreseeable future. We completed the acquisition of Medix at the beginning of the fourth quarter
of 2010, two acquisitions in 2009, four acquisitions in 2008, one in 2007, and three in 2006. We intend to continue to acquire additional
technologies,  products,  or  businesses  and  these  acquisitions  could  be  significant.  These  actions  would  likely  affect  our  future  capital
requirements and the adequacy of our available funds. In order to finance future acquisitions, we may be required to raise additional funds
through public or private financings, strategic relationships or other arrangements. Any equity financing may be dilutive to stockholders
and debt financing, if available, may involve restrictive covenants and increase our cost of capital.

We have a $50 million revolving credit facility with Wells Fargo Bank, National Association (“Wells Fargo”). The revolving credit
facility contains covenants, including covenants relating to liquidity and other financial measurements, and provides for events of default,
including failure to pay any interest when due, failure to perform or observe covenants, bankruptcy or insolvency events and the occurrence
of  a  material  adverse  effect.  We  have  granted  Wells  Fargo  a  security  interest  in  substantially  all  of  our  assets.  We  did  not  draw  on  the
facility during 2010. We have no other significant credit facilities.

Global capital markets have been, and may continue to be, disrupted and volatile. The cost and availability of equity and debt funding
has been and may continue to be adversely affected by illiquid capital and credit markets. Some lenders have reduced or, in some cases,
ceased to provide funding to borrowers. We believe that we have adequate liquidity to meet our present needs. Continued turbulence in the
United States and international financial markets, however, could adversely affect the cost and availability of financing to us in the future
and limit our ability to acquire products, other assets, or businesses.

Cash provided by operations decreased by $15.0 million for the year ended December 31, 2010 to $11.5 million, compared to $26.6
million in 2009. The sum of our net income and certain non-cash expense items, such as reserves, depreciation and amortization, and share
based  compensation  was  approximately  $27.6  million  in  2010,  compared  to  $24.7  million  in  2009.  The  aggregate  impact  of  changes  in
certain operating assets and liabilities was a cash outflow of $16.1 million in 2010 compared to a cash inflow of $1.9 million in 2009, in
particular accounts receivable, inventories and accounts payable.

Cash used in investing activities was $17.9 million for the year ended December 31, 2010, compared to $51.8 million in 2009. We
used  $4.2  million  and  $2.6  million  of  cash  to  acquire  property  and  equipment,  during  the  years  ended  December  31,  2010  and  2009,
respectively. We used $13.4 million of cash to acquire businesses during the year ended December 31, 2010 compared with $47.2 million
during  the  year  ended  December  31,  2009.  During  the  year  ended  December  31,  2010  we  capitalized  $344,000  of  internal  use  software
development costs compared with $1.0 million in 2009. In addition, we purchased and sold $975,000 of marketable securities in 2010 and
purchased $965,000 of marketable securities during the year ended December 31, 2009.

Cash  provided  by  financing  activities  was  $1.7  million  in  the  year  ended  December  31,  2010,  compared  to  $489,000  in  2009.  We
received  cash  from  sales  of  our  stock  pursuant  to  our  stock  awards  plans  and  our  employee  stock  purchase  plan  in  the  amount  of  $2.5
million  and  $1.1  million  in  the  year  ended  December  31,  2010  and  2009,  respectively.  In  2010,  we  realized  an  excess  tax  benefit  of
$551,000 on the exercise of employee stock options that was recorded as an increase to stockholders’ equity. In 2009 our after-tax cost of
stock-based compensation was $159,000 more than the tax benefit we received from those arrangements which was recorded as a decrease
to stockholders’ equity. We repaid $1.4 million and $429,000 under term loan agreements in the years ended December 31, 2010 and 2009,
respectively.

Comparison of 2009 and 2008

As of December 31, 2009, we had cash, cash equivalents, and short-term investments of $33.5 million, stockholders’ equity of $243.6
million, and working capital of $75.2 million, compared with cash and cash equivalents of $56.9 million, stockholders’ equity of $226.4
million, and working capital of $97.6 million as of December 31, 2008.

We believe that our current cash and cash equivalents and any cash generated from operations will be sufficient to meet our ongoing
operating and capital requirements for the foreseeable future. We completed two acquisitions in 2009 including Alpine Biomed at the end
of the third quarter, four acquisitions in 2008, one in 2007, and three in 2006. We intend to continue to acquire additional technologies,
products, or businesses and these acquisitions could be significant. These actions would likely affect our future capital requirements and the
adequacy  of  our  available  funds.  In  order  to  finance  future  acquisitions,  we  may  be  required  to  raise  additional  funds  through  public  or
private financings, strategic relationships or other arrangements. Any equity financing

may be dilutive to stockholders and debt financing, if available, may involve restrictive covenants and increase our cost of capital.

We have a $25 million revolving credit facility with Wells Fargo Bank, National Association (“Wells Fargo”). The revolving credit
facility contains covenants, including covenants relating to liquidity and other financial measurements, and provides for events of default,
including failure to pay any interest when due, failure to perform or observe covenants, bankruptcy or insolvency events and the occurrence
of a material adverse effect. We have granted Wells Fargo a security interest in all of our assets. We did not draw on the facility during
2009. We have no other significant credit facilities.

United States and international financial markets, however, could adversely affect the cost and availability of financing to us in the future
and limit our ability to acquire products, other assets, or businesses.

Cash provided by operations increased by $14.7 million for the year ended December 31, 2009 to $26.6 million, compared to $11.8
million in 2008. The sum of our net income and certain non-cash expense items, such as reserves, depreciation and amortization, and share
based  compensation  was  approximately  $24.7  million  in  2009,  compared  to  $26.4  million  in  2008.  The  aggregate  impact  of  changes  in
certain operating assets and liabilities was a cash inflow of $1.9 million in 2009 compared to a cash outflow of $14.6 million in 2008. In
particular, while the carrying amounts of accounts receivable and inventory, exclusive of those items acquired in acquisitions, resulted in a
use of cash of $10.3 million in 2008, they resulted in a source of cash of $662,000 in 2009.

Cash used in investing activities was $51.8 million for the year ended December 31, 2009, compared to $34.0 million in 2008. We
used  $2.6  million  and  $3.6  million  of  cash  to  acquire  property  and  equipment,  during  the  years  ended  December  31,  2009  and  2008,
respectively. We used $47.2 million of cash to acquire businesses during the year ended December 31, 2009 compared with $29.0 million
during the year ended December 31, 2008. During the year ended December 31, 2009 we recorded $1.0 million of internal use software
development costs compared with $1.5 million in 2008. In addition, we purchased $965,000 of marketable securities in 2009 and purchased
and sold $12.1 million of marketable securities during the year ended December 31, 2008.

Cash provided by financing activities was $489,000 in the year ended December 31, 2009, compared to $69.1 million in 2008. We
raised an aggregate of $99.3 million through underwritten registered public offerings of our common stock in April and May 2008 with no
similar transactions in 2009. We received cash from sales of our stock pursuant to our stock awards plans and our employee stock purchase
plan in the amount of $1.1 million and $2.9 million in the year ended December 31, 2009 and 2008, respectively. In 2009 our after-tax cost
of stock-based compensation was $159,000 more than the tax benefit we received from those arrangements, compared with an excess tax
benefit  of  $2.2  million  in  2008.  These  amounts  were  recorded  as  a  decrease  to  stockholders’  equity  in  2009  and  as  an  increase  to
stockholders’  equity  in  2008.  We  repaid  $429,000  under  term  loan  agreements  in  the  year  ended  December  31,  2009.  During  the  year
ended  December  31,  2008,  we  borrowed  $6.0  million  under  our  revolving  line  of  credit  and  we  repaid  $25.2  million  on  our  term  loan
agreements and $16.1 million on our revolving credit facility.

Future Liquidity

Our future liquidity and capital requirements will depend on numerous factors, including the:

•

•

  Amount and timing of revenue;

  Extent to which our existing and new products gain market acceptance;

Table of Contents

•

•

•

•

  Extent to which we make acquisitions;

  Cost and timing of product development efforts and the success of these development efforts;

  Cost and timing of marketing and selling activities; and

  Availability of borrowings under line of credit arrangements and the availability of other means of financing.

Contractual Obligations

In  the  normal  course  of  business,  we  enter  into  obligations  and  commitments  that  require  future  contractual  payments.  The
commitments  result  primarily  from  firm,  noncancellable  purchase  orders  placed  with  contract  vendors  that  manufacture  some  of  the
components used in our medical devices and related disposable supply products, as well as commitments for leased office equipment and
term  loans.  The  following  table  summarizes  our  contractual  obligations  and  commercial  commitments  as  of  December  31,  2010  (in
thousands):

Purchase obligations are defined as agreements to purchase goods or services that are enforceable and legally binding. Included in the
purchase  obligations  category  above  are  obligations  related  to  purchase  orders  for  inventory  purchases  under  our  standard  terms  and
conditions  and  under  negotiated  agreements  with  vendors.  We  expect  to  receive  consideration  (products  or  services)  for  these  purchase
obligations.  The  purchase  obligation  amounts  do  not  represent  all  anticipated  purchases  in  the  future,  but  represent  only  those  items  for
which we are contractually obligated. The table above does not include obligations under employment agreements for services rendered in
the ordinary course of business.

We are not able to reasonably estimate the timing of any potential payments for uncertain tax positions under ASC 740,  Accounting
for Uncertainty in Income Taxes – an interpretation of FASB Statement 109 . As a result, the preceding table excludes any potential future
payments  related  to  our ASC  740  liability  for  uncertain  tax  positions.  See  Note  14  of  our  consolidated  financial  statements  for  further
discussion on income taxes.

Quantitative and Qualitative Disclosures about Market Risk

We develop products in the U.S, Canada, Argentina, and Europe and sell those products into more than 100 countries throughout the
world. As a result, our financial results could be affected by factors such as changes in foreign currency exchange rates or weak economic
conditions in foreign markets. Most of our sales in Europe and Asia are denominated in U.S. Dollars and Euros and with the acquisitions of
Xltek in November 2007 and Medix in 2010, a small portion of our sales are now denominated in Canadian dollars and Argentine pesos. As
our sales in currencies other than the U.S. dollar increase, our exposure to foreign currency fluctuations may increase.

In  addition,  changes  in  exchange  rates  also  may  affect  the  end-user  prices  of  our  products  compared  to  those  of  our  foreign
competitors, who may be selling their products based on local currency pricing. These factors may make our products less competitive in
some countries.

If the U.S. Dollar uniformly increased or decreased in strength by 10% relative to the currencies in which our sales were denominated,
our net income would have correspondingly increased or decreased by an immaterial amount for the year ended December 31, 2010. Our
interest income is sensitive to changes in the general level of interest rates in the U.S. However, because current market conditions have
resulted in historically low rates of return on our investments, a hypothetical decrease of 10% in market interest rates would not result in a
material decrease in interest income earned on investments held at December 31, 2010.

When able, we invest excess cash in bank money-market funds or discrete short-term investments. The fair value of our short-term
investments and cash equivalents (“investments”) is sensitive to changes in the general level of interest rates in the U.S., and the fair value
of  these  investments  will  fall  if  market  interest  rates  increase.  However,  since  we  generally  have  the  ability  to  hold  the  investments  to
maturity, these declines in fair value may never be realized. If market interest rates were to increase by 10% from levels at December 31,
2010, the fair value of our investments would decline by an immaterial amount.

All of the potential changes noted above are based on sensitivity analyses performed on our financial position as of December 31,
2010. Actual results may differ as our analysis of the effects of changes in interest rates does not account for, among other things, sales of
securities prior to maturity and repurchase of replacement securities, the change in mix or quality of the investments in the portfolio, and
changes in the relationship between short-term and long-term interest rates.

Off-Balance Sheet Arrangements

Under our bylaws, we have agreed to indemnify our officers and directors for certain events or occurrences arising as a result of the
officer or director’s serving in such capacity. We have a directors and officers liability insurance policy that limits our exposure and enables
us to recover a portion of any future amounts paid resulting from the indemnification of our officers and directors. In addition, we enter
into indemnification agreements with other parties in the ordinary course of business. In some cases we have obtained liability insurance
providing coverage that limits our exposure for these other indemnified matters. We have not incurred material costs to defend lawsuits or
settle  claims  related  to  these  indemnification  agreements.  We  believe  the  estimated  fair  value  of  these  indemnification  agreements  is
minimal and have not recorded a liability for these agreements as of December 31, 2010. We had no other off-balance sheet arrangements
during any of fiscal 2010, 2009 or 2008 that had, or are reasonably likely to have, a material effect on our consolidated financial condition,
results of operations, or liquidity.

Selected Quarterly Financial Data (Unaudited)

The  following  table  presents  our  operating  results  for  each  of  the  eight  quarters  in  the  period  ending  December  31,  2010.  The
information for each of these quarters is unaudited and has been prepared on the same basis as our audited financial statements appearing
elsewhere  in  this  report.  As  discussed  in  Note  20, Immaterial  Corrections  to  Prior  Period  Financial  Statements  in  the Notes  to
Consolidated  Financial  Statements  of  our  Consolidated  Financial  Statements  contained  herein,  subsequent  to  the  issuance  of  our
consolidated financial statements for the fiscal year ended December 31, 2009 and our quarterly consolidated financial statements for the
quarter ended September 30, 2010, we discovered immaterial errors in previously issued financial statements. These errors were corrected
for all quarters and years that were affected. The quarterly information presented below reflects the correction of these errors. The impact
of the errors was immaterial to all of the period presented.

In  the  opinion  of  our  management,  all  necessary  adjustments,  consisting  only  of  normal  recurring  adjustments,  other  than  the
correction  discussed  in  the  preceding  paragraph,  have  been  included  to  present  fairly  the  unaudited  quarterly  results  when  read  in
conjunction  with  our  audited  consolidated  financial  statements  and  the  related  notes  appearing  elsewhere  in  this  report.  These  operating
results are not necessarily indicative of the results of any future period.

ITEM 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the rules of the Securities and Exchange Commission, “disclosure controls and procedures” are controls and other procedures
that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Securities Exchange Act
of  1934  is  recorded,  processed,  summarized  and  reported  within  the  time  periods  specified  in  the  rules  and  forms  of  the  Securities  and
Exchange Commission. Disclosure controls and procedures include, “without limitation, controls and procedures designed to ensure that
information required to be disclosed by us in our reports that we file or submit under the Securities Exchange Act of 1934 is accumulated
and  communicated  to  our  management,  including  our  chief  executive  officer  and  chief  financial  officer,  as  appropriate,  to  allow  timely
decisions regarding required disclosure.

Our management, with the participation of our chief executive officer and our chief financial officer, has evaluated the effectiveness
of our disclosure controls and procedures as of December 31, 2010. Our chief executive officer and chief financial officer determined that
as of December 31, 2010 our disclosure controls and procedures were effective for the purpose set forth above.

Internal Control Over Financial Reporting

(a) Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule
13a-15-(f) promulgated under the Securities Exchange Act of 1934. Under the supervision and with the participation of our management,
including  our  principal  executive  officer  and  our  principal  financial  officer,  we  assessed  the  effectiveness  of  our  internal  control  over
financial reporting as of December 31, 2010. In making this assessment, our management used the criteria set forth by the Committee of
Sponsoring  Organizations  of  the  Treadway  Commission  (COSO)  in  the Internal  Control-Integrated  Framework.  Our  management  has
concluded that, as of December 31, 2010, our internal control over financial reporting is effective based on these criteria.

We acquired Medix Industrial y Commercial S.A. (“Medix) in October 2010 and as permitted by SEC guidance, we excluded from
our  assessment  of  the  effectiveness  of  our  internal  control  over  financial  reporting  as  of  December  31,  2010,  the  internal  control  over
financial reporting of this entity. Total assets including goodwill and intangible assets related to Medix of $30.2 million as of December 31,
2010,  and  revenue  of  $7.1  million  for  the  period  from  the  date  of  acquisition  to  December  31,  2010,  were  included  in  our  consolidated
financial  statements  as  of  and  for  the  year  ended  December  31,  2010.  Our  assessment  of  our  internal  control  over  financial  reporting
excluded an evaluation of the internal control over financial reporting of this entity as of December 31, 2010.

Our independent registered public accounting firm, Deloitte & Touche LLP. have audited the consolidated financial statements and
financial  statement  schedule  included  in  this  annual  report.  They  also  audited  the  effectiveness  of  our  internal  control  over  financial
reporting as of December 31, 2010 as stated in their report included in this annual report.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Natus Medical Incorporated

San Carlos, California

We have audited the internal control over financial reporting of Natus Medical Incorporated and subsidiaries (the “Company”) as of
December  31,  2010,  based  on  criteria  established  in  Internal  Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring
Organizations  of  the  Treadway  Commission.  As  described  in  Management’s  Report  on  Internal  Control  Over  Financial  Reporting,
management excluded from its assessment the internal control over financial reporting of Medix I.C.S.A. (“Medix”) which was acquired on
October 12, 2010, whose financial statements constitute 10% of total assets, 5% of net assets, 3% of revenues, and 2% of net income of the
consolidated  financial  statement  amounts  as  of  and  for  the  year  ended  December  31,  2010. Accordingly,  our  audit  did  not  include  the
internal  control  over  financial  reporting  at  Medix.  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.  Our  responsibility  is  to  express  an  opinion  on  the
Company’s internal control over financial reporting based on our audit.

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

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the Company’s principal
executive  and  principal  financial  officers,  or  persons  performing  similar  functions,  and  effected  by  the  Company’s  board  of  directors,
management,  and  other  personnel  to  provide  reasonable  assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of
financial statements for external purposes in accordance with generally accepted accounting principles. 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  the  inherent  limitations  of  internal  control  over  financial  reporting,  including  the  possibility  of  collusion  or  improper
management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also,
projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that
the  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,  the  Company  maintained,  in  all  material  respects,  effective  internal  control  over  financial  reporting  as  of
December 31, 2010, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission.

We  have  also  audited,  in  accordance  with  the  standards  of  the  Public  Company Accounting  Oversight  Board  (United  States),  the
consolidated financial statements and the financial statement schedule at Item 15(a)(2) of this annual report as of and for the year ended
December 31, 2010 of the Company and our report dated March 14, 2011 expressed an unqualified opinion on those financial statements
and the financial statement schedule and included an explanatory paragraph relating to the adoption of Accounting Standards Codification
Topic 805, Business Combinations (formerly SFAS 141R).

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Natus Medical Incorporated

San Carlos, California

We have audited the accompanying consolidated balance sheets of Natus Medical Incorporated and subsidiaries (the “Company”) as
of December 31, 2010 and 2009, and the related consolidated statements of operations, stockholders’ equity and comprehensive income,
and cash flows for each of the three years in the period ended December 31, 2010. Our audits also included the financial statement schedule
listed in the Index at Item 15(a)(2). These financial statements and the financial statement schedule are the responsibility of the Company’s
management. Our responsibility is to express an opinion on these financial statements based on our audits.

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

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Natus Medical
Incorporated and subsidiaries at December 31, 2010 and 2009, and the results of their operations and their cash flows for each of the three
years in the period ended December 31, 2010, in conformity with accounting principles generally accepted in the United States of America.
Also, in our opinion such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a
whole, present fairly, in all material respects, the information set forth therein.

As  discussed  in  Note  1  to  the  consolidated  financial  statements,  effective  January  1,  2009,  the  Company  adopted  Accounting

Standards Codification 805, Business Combinations (formerly SFAS 141R).

We  have  also  audited,  in  accordance  with  the  standards  of  the  Public  Company Accounting  Oversight  Board  (United  States),  the
Company’s  internal  control  over  financial  reporting  as  of  December  31,  2010,  based  on  the  criteria  established  in  Internal  Control—
Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 14,
2011, expressed an unqualified opinion on the Company’s internal control over financial reporting.

NATUS MEDICAL INCORPORATED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Years Ended December 31, 2010, 2009 and 2008

1—ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

Organization

Natus Medical Incorporated (“Natus”, the “Company”, “we”, “our”) was incorporated in California in May 1987 and reincorporated
in Delaware in August 2000. Natus is a leading provider of healthcare products used for the screening, detection, treatment, monitoring and
tracking  of  common  medical  ailments  in  newborn  care,  hearing  impairment,  neurological  dysfunction,  epilepsy,  sleep  disorders,  and
include  computerized  neurodiagnostic  systems  for  audiology,  neurology,
balance  and  mobility  disorders.  Product  offerings 
polysomnography,  and  neonatology,  as  well  as  newborn  care  products  such  as  hearing  screening  systems,  phototherapy  devices  for  the
treatment of newborn jaundice, head-cooling products for the treatment of brain injury in newborns, incubators to control the newborn’s
environment,  and  software  systems  for  managing  and  tracking  disorders  and  diseases  for  public  health  laboratories.  The  Company’s
headquarters are in San Carlos, California.

We  have  completed  a  number  of  acquisitions  since  2003,  consisting  of  either  the  purchase  of  a  company,  substantially  all  of  the
assets of a company or individual products or product lines. Our significant acquisitions are as follows: Neometrics in 2003; Fischer-Zoth
in  2004;  Bio-logic,  Deltamed,  and  Olympic  in  2006;  Xltek  in  2007;  Sonamed,  Schwarzer  Neurology,  and  Neurocom  in  2008;  Hawaii
Medical and Alpine Biomed in 2009; and Medix in 2010.

Principles  of  Consolidation—  The  accompanying  consolidated  financial  statements  include  the  accounts  of  the  Company  and  its

wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates—The preparation of financial statements in conformity with accounting principles generally accepted in the United
States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities in the consolidated financial statements and the reported amount of revenue and
expenses  during  the  reporting  period.  Such  estimates  include  allowances  for  potentially  uncollectible  accounts  receivable,  valuation  of
inventory,  intangible  assets,  goodwill,  share-based  compensation,  deferred  income  taxes,  reserves  for  warranty  obligations,  and  the
provision for income taxes. Actual results could differ from those estimates.

Revenue  Recognition—Revenue,  net  of  discounts,  is  recognized  from  sales  of  medical  devices  and  supplies,  including  sales  to
distributors,  when  the  following  conditions  have  been  met:  a  purchase  order  has  been  received,  title  has  transferred,  the  selling  price  is
fixed  or  determinable,  and  collection  of  the  resulting  receivable  is  reasonably  assured.  Terms  of  sale  for  most  domestic  sales  are  FOB
origin, reflecting that title and risk of loss are assumed by the purchaser at the shipping point; however, terms of sale for some neurology,
sleep-diagnostic,  and  head  cooling  systems  are  FOB  destination,  reflecting  that  title  and  risk  of  loss  are  assumed  by  the  purchaser  upon
delivery. Terms of sales to international distributors are generally EXW, reflecting that goods are shipped “ex works,” in which title and
risk of loss are assumed by the distributor at the shipping point.

We  have  historically  applied  the  software  revenue  recognition  rules  as  prescribed  by Accounting  Standards  Codification  (“ASC”)
Subtopic  985-605  to  sales  of  certain  of  our  diagnostic  neurology  and  hearing  systems  (“products  containing  embedded  software”).  In
October 2009, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. (“ASU”) 2009-14,  Certain
Revenue  Arrangements  That  Include  Software  Elements,  which  amended ASC  Subtopic  985-605.  This ASU  removes  tangible  products
containing software components and non-software components that function together to deliver the product’s essential functionality from
the scope of the software revenue recognition rules. We adopted the provisions of ASU 2009-14 prospectively on January 1, 2010 for new
or significantly modified revenue arrangements. The

F-7

 
Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
Years Ended December 31, 2010, 2009 and 2008

adoption did not have a significant impact on our revenue or results of operations for the year ended December 31, 2010. In the case of the
Company’s products containing embedded software, we have determined that the hardware and software components function together to
deliver the products’ essential functionality, and therefore, the revenue from the sale of these products no longer falls within the scope of
the software revenue recognition rules. Our revenue recognition policies for sales of these products are now substantially the same as for
our other tangible products.

Revenue  from  sales  of  certain  of  our  products  that  remain  within  the  scope  of  the  software  revenue  recognition  rules  under ASC

Subtopic 985-605 is not significant.

We  previously  accounted  for  arrangements  with  multiple  deliverables  under ASC  Topic  605,  where  revenue  was  allocated  to  the
deliverables based on vendor specific objective evidence (“VSOE”). In October 2009 the FASB issued ASU 2009-13,  Multiple Deliverable
Revenue Arrangements, which amends ASC Topic 605. We adopted the provisions of ASU 2009-13 prospectively on January 1, 2010 for
new or significantly modified revenue arrangements. The adoption did not have a significant impact on our revenue or results of operations
for the year ended December 31, 2010. Under the revenue recognition rules for tangible products as amended by ASU 2009-13, we now
allocate  revenue  from  arrangements  with  multiple  deliverables  to  each  of  the  deliverables  based  upon  their  relative  selling  prices  as
determined by a selling-price hierarchy. A deliverable in an arrangement qualifies as a separate unit of accounting if the delivered item has
value to the customer on a stand-alone basis. The principal deliverables in our multiple deliverable arrangements that qualify as separate
units  of  accounting  consist  of  (i)  sales  of  medical  devices  and  supplies,  (ii)  installation  services,  (iii)  extended  service  and  maintenance
agreements, and (iv) upgrades to embedded software.

The  new  rules  establish  a  hierarchy  to  determine  the  selling  price  to  be  used  for  allocating  revenue  to  deliverables  as  follows:
(i) vendor-specific objective evidence of fair value (“VSOE”), (ii) third-party evidence of selling price (“TPE”), and (iii) best estimate of
the selling price (“ESP”). VSOE of fair value is defined as the price charged when the same element is sold separately, or if the element
has not yet been sold separately, the price for the element established by management having the relevant authority when it is probable that
the  price  will  not  change  before  the  introduction  of  the  element  into  the  marketplace.  VSOE  generally  exists  only  when  we  sell  the
deliverable separately and is the price actually charged for that deliverable. We have previously established VSOE for substantially all of
the deliverables in our multiple element arrangements; however, in the future we may rely on ESPs, reflecting our best estimates of what
the selling prices of elements would be if they were sold regularly on a stand-alone basis, to establish the amount of revenue to allocate to
the deliverable. TPE generally does not exist for our products because of their uniqueness.

For products shipped under FOB origin or EXW terms, delivery is generally considered to have occurred when shipped. Undelivered
elements in our sales arrangements, which are not considered to be essential to the functionality of a product, generally include installation
or training services that are performed after the related products have been delivered. Revenue related to undelivered installation services is
deferred  until  such  time  as  installation  is  complete  at  the  customer’s  site.  Revenue  related  to  training  services  is  recognized  when  the
service is provided. Fair value for installation or training services is based on the price charged when the service is sold separately. The fair
value of installation and training services is based upon billable hourly rates and the estimated time to complete the service.

Revenue from extended service and maintenance agreements, for both medical devices and data management systems, is recognized
ratably over the service period. Freight charges billed to customers are included in revenue and freight-related expenses are charged to cost
of revenue. Advance payments from customers are recorded as deferred revenue and recognized as revenue as otherwise described above.
We

generally  do  not  provide  rights  of  return  on  products.  We  accept  trade-ins  of  our  own  and  competitive  medical  devices.  Trade-ins  are
recorded  as  a  reduction  of  the  replacement  medical  device  sale.  Provisions  are  made  for  initial  standard  warranty  obligations  that  are
generally one year in length.

More  than  90%  of  the  hospitals  in  the  U.S.  are  members  of  Group  Purchasing  Organizations  (“GPO”s),  which  negotiate  volume
purchase prices for member hospitals, group practices, and other clinics. Our agreements with GPOs typically contain preferential terms for
the GPO and its members, including provisions for some, if not all, of the following:

•

•

•

•

•

  Negotiated pricing for all group members;

  Volume discounts and other preferential terms on their member’s direct purchases from us;

  Promotion of Natus’ products by the GPO to its members;

  Payment of marketing fees by Natus to the GPO, usually based on purchasing experience of group members; and

  Non-recourse cancellation provisions.

We do not sell products to GPOs. Hospitals, group practices, and other clinics that are members of a GPO purchase products directly
from the Company under the terms negotiated by the GPO. Negotiated pricing and discounts are recognized as a reduction of the selling
price of products at the time of the sale. Revenue from sales to members of GPOs is otherwise consistent with general revenue recognition
policies as previously described.

Cash  and  Cash  Equivalents—All  highly  liquid  debt  instruments  purchased  with  an  original  maturity  of  three  months  or  less  are

classified as cash equivalents.

Short-Term Investments—Fixed-rate guaranteed investment contracts with a commercial bank with a maturity of one year, valued

at cost plus accrued interest that approximates fair value are classified as short-term investments.

Allowance  for  Doubtful Accounts—We  assess  the  sufficiency  of  the  allowance  for  estimated  uncollectible  accounts  receivable.
Estimates are based on historical collection experience within the markets in which we operate and other customer-specific information,
such  as  bankruptcy  filings  or  liquidity  problems  of  customers.  When  it  is  determined  that  an  account  receivable  is  uncollectible,  it  is
written off and relieved from the reserve. Any future determination that the allowance for estimated uncollectible accounts receivable is not
properly stated could result in changes in operating expense and results of operations.

Fair Value of Financial Instruments —Financial  instruments  include  cash  and  cash  equivalents,  short-term  investments,  accounts
receivable,  and  accounts  payable.  Cash  and  cash  equivalents  are  reported  at  their  respective  fair  values  on  the  balance  sheet  dates.  The
recorded carrying amount of accounts receivable and accounts payable approximates their fair value due to their short-term maturities.

Inventories—Inventories  are  stated  at  the  lower  of  standard  cost,  which  approximates  actual  cost  on  a  first-in,  first-out  basis,  or
market. We may be exposed to a number of factors that could result in portions of our inventory becoming either obsolete or in excess of
anticipated usage. These factors include, but are not limited to, technological changes, competitive pressures in products and prices, and the
introduction of new product lines. We regularly evaluate our ability to realize the value of inventory based on a combination of factors,
including historical usage rates, forecasted sales, product life cycles, and market acceptance of new products.

Years Ended December 31, 2010, 2009 and 2008

When inventory that is obsolete or in excess of anticipated usage is identified, it is written down to realizable salvage value or an inventory
valuation reserve is established.

Property  and  Equipment—Property  and  equipment  are  stated  at  cost  less  accumulated  depreciation.  Depreciation  expense  is
computed  using  the  straight-line  method  over  estimated  useful  lives  of  the  respective  assets,  which  are  three  to  five  years  for  office
furniture  and  equipment,  three  to  five  years  for  computer  software  and  hardware,  three  to  six  years  for  demonstration  and  loaned
equipment, and 40 years for buildings. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful
life. Land is not depreciated. Costs associated with acquiring and installing software to be used for internal purposes are capitalized.

Long-Lived Assets and Goodwill—Intangible assets with finite lives are amortized over their useful lives; any future changes that
would  limit  their  useful  lives  or  any  determination  that  these  assets  are  carried  at  amounts  greater  than  their  estimated  fair  value  could
result  in  impairment  charges.  Goodwill  and  any  other  intangible  assets  with  indefinite  lives  are  recorded  at  original  cost  and  are  not
amortized.  Any  future  determination  that  these  assets  are  carried  at  amounts  greater  than  their  estimated  fair  value  could  result  in
additional charges, which could impact operating results.

Definite-lived  intangible  assets  are  tested  for  impairment  whenever  changes  in  circumstances  indicate  the  carrying  value  of  these
assets  may  be  impaired.  Impairment  indicators  include,  but  are  not  limited  to,  net  book  value  as  compared  to  market  capitalization,
significant  negative  industry  and  economic  trends,  and  significant  underperformance  relative  to  historical  and  projected  future  operating
results. Impairment is considered to have occurred when the estimated undiscounted future cash flows related to the asset are less than its
carrying value. Estimates of future cash flows involve consideration of many factors including the marketability of new products, product
acceptance and lifecycle, competition, appropriate discount rates, and operating margins.

Intangible assets with definite lives are amortizing using the straight-line and graded methods over periods ranging from seven to 20

years.

Goodwill and indefinite-lived intangible assets are tested for impairment at least annually as of October 1st; this assessment is also
performed  whenever  there  is  a  change  in  circumstances  that  indicates  the  carrying  value  of  these  assets  may  be  impaired.  The
determination of whether any potential impairment of goodwill exists is based upon a two step process. In the first analysis, the fair value
of the reporting unit is compared to the unit’s carrying value, including goodwill, to determine if there is a potential impairment. If the fair
value  exceeds  the  carrying  amount,  the  goodwill  of  the  reporting  unit  is  considered  not  impaired  and  no  further  analysis  or  action  is
required.  If  the  first  analysis  indicates  that  the  carrying  value  exceeds  the  fair  value,  a  second  analysis  is  performed  to  determine  the
amount of the goodwill impairment loss, if any.

In step two of the impairment test, the implied fair value of a reporting unit’s goodwill is compared to the carrying amount of that
goodwill.  The  implied  fair  value  of  the  goodwill  shall  be  determined  in  the  same  manner  as  the  amount  of  goodwill  recognized  in  a
business combination is determined. That is, the entity shall allocate the fair value of a reporting unit to all the assets and liabilities of that
reporting unit, including unrecognized intangible assets as if the reporting unit had been acquired in a business combination and the fair
value  of  the  reporting  unit  was  the  price  paid  to  acquire  the  reporting  unit.  The  excess  of  the  fair  value  of  the  reporting  unit  over  the
amounts assigned to its assets and liabilities is the implied fair value of that goodwill.

To determine the estimated fair value of reporting units, three valuation methodologies are utilized: (i) discounted cash flow analyses,

(ii) market multiples, and (iii) comparative transactions. The valuations

F-10

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
Years Ended December 31, 2010, 2009 and 2008

indicated by these three methodologies are averaged, with the greatest weight placed on discounted cash flow analyses. Discounted cash
flow analyses are dependent upon a number of quantitative and qualitative factors including estimates of forecasted revenue, profitability,
earnings before interest, taxes, depreciation and amortization (i.e. EBITDA) and exit values. The discount rates applied in the discounted
cash flow analyses also have an impact on the estimates of fair value, as use of a higher rate will result in a lower estimate of fair value.
The estimated total fair value of reporting units is reconciled to the Company’s market capitalization.

Our discontinuance in 2010 of the Sonamed Clarity hearing screening line resulted in a write-off of the Sonamed Clarity tradename in

the amount of $300,000.

Research & Development and Capitalized Software Development Costs—Costs incurred in research and development are charged
to operations as incurred. Some of our products include imbedded software which is essential to the product’s functionality. In accordance
with FASB ASC 985-20, Costs of Software to be Sold, Leased or Marketed, costs incurred in the research and development of new software
components  and  enhancements  to  existing  software  components  are  expensed  as  incurred  until  technological  feasibility  has  been
established. We capitalize software development costs when the project reaches technological feasibility and cease capitalization when the
project is ready for release. Software development costs are amortized on a straight-line basis over the estimated useful life of the product.
Amortization begins when the product is available for general release to the customer.

Internal Use Software Development Costs—We account for internal use software development costs in accordance with ASC 350-
40-15, Internal Use Software. In accordance with ASC 350-40-15, costs to develop internal use computer software during the application
development stage are capitalized and reported as a component of intangible assets and amortized on a straight-line basis over the estimated
useful lives of the related software applications.

Share-Based Compensation—We  amortize  share-based  compensation  expense  associated  with  employee  stock  options  under  the
single-option straight line method over the requisite service period, which is generally a four-year vesting period pursuant to ASC Topic
718, Compensation-Stock Compensation. See Note 11.

For employee stock options, the value of each option is estimated on the date of grant using the Black-Scholes option pricing model,
which was developed for use in estimating the value of freely traded options. Our employee stock options have characteristics significantly
different  from  those  of  traded  options.  Similar  to  other  option  pricing  models,  the  Black-Scholes  method  requires  the  input  of  highly
subjective assumptions, including stock price volatility. Changes in the subjective input assumptions can materially affect the estimated fair
value of our employee stock options.

Forfeitures  of  employee  stock  options  are  estimated  at  the  time  of  grant  and  revised,  if  necessary,  in  subsequent  periods  if  actual
forfeitures  differ  from  initial  estimates.  Share-based  compensation  expense  is  recorded  net  of  estimated  forfeitures,  such  that  expense  is
recorded only for those share-based awards that are expected to vest.

The cash flow resulting from the tax benefits resulting from tax deductions in excess of the compensation cost recognized for those
options  (excess  tax  benefits)  is  classified  as  a  cash  inflow  from  financing  activities  and  a  cash  outflow  from  operating  activities  in  our
Statements of Cash Flows. We treat tax deductions from certain stock option exercises as being realized when they reduce taxes payable in
accordance with relevant tax law.

We also recognize share-based compensation associated with Restricted Stock Awards and Restricted Stock Units in accordance with

ASC Topic 718, Compensation-Stock Compensation.

Years Ended December 31, 2010, 2009 and 2008

Uncertain  Tax  Positions—We  recognize  the  tax  benefit  of  uncertain  tax  positions  in  the  financial  statements  in  accordance  with
ASC Topic 740, Income Tax. When the tax position is deemed more likely than not of being sustained, we recognize the largest amount of
tax benefit that is greater than 50 percent likely of being ultimately realized upon settlement, in accordance with ASC 740-10-05.

Foreign Currency—The  functional  currency  of  our  foreign  subsidiaries  is  generally  the  local  currency  of  the  country  where  the
subsidiary  is  located.  Accordingly,  foreign  currency  translation  exchange  adjustments  relating  to  the  translation  of  foreign  subsidiary
financial statements are included as a component of accumulated other comprehensive income (loss). We recorded $(719,000), $685,000,
and $(14.3) million of foreign currency translation adjustments for the years ended December 31, 2010, 2009 and 2008, respectively. We
changed the functional currency of Xltek from the Canadian dollar to the U.S. Dollar on January 1, 2009.

Gains and losses from transactions denominated in currencies other than the functional currencies of the Company and its subsidiaries
are included in other income and expense. In 2010, 2009 and 2008, net foreign currency transactions gains and (losses) were $(521,000),
$520,000 and $1,620,000, respectively. Foreign currency gains and losses result primarily from fluctuations in the exchange rate between
the US Dollar, Canadian Dollar, Euro, Argentine Peso and Danish Kroner.

Comprehensive Income—We report by major components and as a single total the change in our net assets during the period from
non-owner  sources  in  accordance  with ASC  Topic  220,  Comprehensive Income.  The  consolidated  statement  of  comprehensive  income
(loss) has been included with the consolidated statement of stockholders’ equity. Accumulated other comprehensive income (loss) consists
of net unrealized gains and losses on available-for-sale securities and translation gains and losses on foreign subsidiary financial statements.

Basic and Diluted Net Income per Share—We  compute  net  income  per  share  in  accordance  with ASC  Topic  260,  Earnings  per
Share. Basic net income per share is based upon the weighted average number of common shares outstanding during the period. Diluted net
income  per  share  is  based  upon  the  weighted  average  number  of  common  shares  outstanding  and  dilutive  common  stock  equivalents
outstanding during the period. Common stock equivalents are options granted and shares of restricted stock issued under our stock awards
plans and are calculated under the treasury stock method. Common equivalent shares from unexercised stock options and restricted stock
are excluded from the computation when there is a loss as their effect is anti-dilutive, or if the exercise price of such options is greater than
the average market price of the stock for the period.

For  the  year  ended  December  31,  2010,  common  stock  equivalents  of  1,125,006  were  included  in  the  weighted  average  shares
outstanding used to calculate diluted income per share, while 1,090,401 shares were excluded from the calculation because of their anti-
dilutive effect. For the year ended December 31, 2009, common stock equivalents of 824,516 were included in the weighted average shares
outstanding used to calculate diluted income per share, while 1,168,704 shares were excluded from the calculation because of their anti-
dilutive  effect.  For  the  year  ended  December  31,  2008,  common  stock  equivalents  of  1,206,000  were  included  in  the  weighted  average
shares outstanding used to calculate diluted income per share, while 525,000 shares were excluded from the calculation because of their
anti-dilutive effect.

Certain Significant Risks and Uncertainties—Financial instruments that potentially subject us to credit risk consist principally of
cash and cash equivalents, short-term investments, and accounts receivable. Cash and cash equivalents consist primarily of cash in bank
accounts and investments in money market funds. To minimize our exposure to credit risk, our short-term investments consists exclusively
of highly liquid, investment-grade financial instruments.

We  sell  our  products  primarily  to  hospitals  and  medical  institutions.  Customers  are  generally  not  required  to  provide  collateral  or
other  security  to  support  accounts  receivable. Allowances  for  estimated  potential  bad  debt  losses  are  maintained.  No  single  customer  or
distributor accounted for more than 10% of accounts receivable at December 31, 2010, 2009 or 2008.

Recent Accounting Pronouncements

In December 2010, the FASB issued Accounting Standards Update (“ASU”) 2010-28,  Intangibles—Goodwill and Other (Topic 350):
When  to  Perform  Step  2  of  the  Goodwill  Impairment  Test  for  Reporting  Units  with  Zero  or  Negative  Carrying  Amounts. ASU  2010-28
modifies Step 1 of the goodwill impairment test so that for reporting units with zero or negative carrying amounts, an entity is required to
perform Step 2 of the goodwill impairment test if it is more likely than not based on an assessment of qualitative indicators that goodwill
impairment  exists.  In  determining  whether  it  is  more  likely  than  not  that  goodwill  impairment  exists,  an  entity  should  consider  whether
there  are  any  adverse  qualitative  factors  indicating  that  impairment  may  exist. ASU  2010-28  is  effective  for  fiscal  years,  and  interim
periods within those years, beginning after December 15, 2010. Early adoption is not permitted. We do not expect adoption of this standard
to have a material impact on our financial position, results of operations, or cash flows.

In February 2010, the FASB issued ASU 2010-09,  Subsequent Events (Topic 855) which updates the guidance in ASC Topic 855,
Subsequent Events, to no longer require companies that file with the SEC to indicate the date through which they have analyzed subsequent
events. This updated guidance became effective immediately upon issuance.

In January 2010, the FASB issued ASU 2010-06,  Improving  Disclosures  about  Fair  Value  Measurements  (Topic  820): Fair  Value
Measurement. ASU  2010-06  requires  new  disclosures  on  the  amount  of  and  reason  for  transfers  in  and  out  of  Level  1  and  2  fair  value
measurements, disclosure of activities, including purchases, sales, issuances, and settlements within Level 3 fair value measurements, and
clarifies existing disclosure requirements on levels of disaggregation and disclosures about inputs and valuation techniques. The Company
adopted ASU 2010-06 on January 1, 2010. The adoption of ASU 2010-06 did not impact our financial position, results of operations, and
cash flows.

In December 2007, the FASB issued ASC Topic 805, Business Combinations, which expands the definition of a business combination
and  requires  the  fair  value  of  the  purchase  price  of  an  acquisition,  including  the  issuance  of  equity  securities,  to  be  determined  on  the
acquisition date. ASC Topic 805 also requires that all assets, liabilities, contingent consideration and contingencies of an acquired business
be  recorded  at  fair  value  at  the  acquisition  date.  In  addition  acquisition  costs  are  generally  expensed  as  incurred  and  restructuring  costs
generally are expensed in periods subsequent to the acquisition date. Changes in accounting for deferred tax asset valuation allowances and
acquired income tax uncertainties resulting from new information obtained during the measurement period about facts and circumstances
that  existed  as  of  the  acquisition  date  will  result  in  an  adjustment  to  goodwill,  while  all  other  changes  in  these  items  are  recognized  as
adjustments to income tax expense. We adopted ASC Topic 805 on January 1, 2009.

2— BUSINESS COMBINATIONS

Medix—We acquired Medix Industrial y Commercial S.A. (“Medix”) on October 12, 2010 pursuant to an Agreement and Plan of
Merger. Medix is a leader in the development, manufacturing, and sales of devices for newborn care in Latin America. Medix, based in
Argentina,  manufactures  incubators  for  use  in  hospital  nurseries  and  NICU’s,  transport  incubators  for  use  in  ambulances  and  other
emergency vehicles, infant warmers, and LED based phototherapy devices.

NATUS MEDICAL INCORPORATED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
Years Ended December 31, 2010, 2009 and 2008

The Company acquired all of the capital stock of Medix for $14.1 million in cash, excluding direct costs of the acquisition, with the
potential  for  additional  purchase  consideration  if  certain  revenue  targets  are  met  in  2011  and  2012. A  total  of  $297,000  of  direct  costs
associated with the acquisition was expensed as incurred and reported as a component of general and administrative expenses.

In  accordance  with ASC  805-10,  the  acquisition  has  been  accounted  for  as  a  purchase  business  combination.  Under  the  purchase
method of accounting, the assets acquired and liabilities assumed from Medix at the date of acquisition are recorded in the consolidated
financial  statements  at  their  respective  fair  values  as  of  the  acquisition  date.  The  excess  of  the  purchase  price  over  the  fair  value  of  the
acquired  net  assets  has  been  recorded  as  goodwill  in  the  amount  of  $4.8  million.  Medix’s  results  of  operations  are  included  in  the
consolidated financial statements from the date of the acquisition.

The  determination  of  estimated  fair  value  of  acquired  assets  and  liabilities  requires  management  to  make  significant  estimates  and
assumptions. We determined the fair value by applying established valuation techniques, based on information that management believed
to be relevant to this determination. The Company also hired independent third parties to assist in the valuation of real estate, intangible
assets, goodwill, and additional purchase consideration.

The following table summarizes the purchase price allocation of the fair value of the assets acquired and liabilities assumed at the

date of acquisition, (in thousands):

Valuing certain components of the acquisition, including primarily accounts receivable, inventory, identifiable intangible assets, real
estate, deferred taxes, accrued warranty costs, accounts payable, other accrued expenses, and contingent earnout obligation required us to
make  estimates  that  may  be  adjusted  in  the  future;  consequently  the  purchase  price  allocation  is  considered  preliminary.  Final
determination of these estimates could result in an adjustment to the preliminary purchase price allocation, with an offsetting adjustment to
Goodwill.  In  addition,  the  purchase  consideration  paid  to  the  sellers  is  subject  to  adjustment  pursuant  to  a  minimum  working  capital
provision of the purchase agreement.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
Years Ended December 31, 2010, 2009 and 2008

Identifiable  intangible  assets.    Intangible assets included in the purchase price allocation consist of: (i) technology of $1.6 million
assigned an average economic life of 20 years being amortized on the straight line method, (ii) customer-related intangible assets of $2.3
million assigned an economic life of nine years being amortized on the straight line method, and (iii) tradenames of $1.0 million that have
an indefinite life and are not being amortized.

Goodwill.    Approximately $4.8 million has been allocated to goodwill. Goodwill represents the excess of the purchase price over the
fair  value  of  the  underlying  net  tangible  and  intangible  assets.  This  goodwill  is  expected  to  be  non-deductible  for  tax  purposes.  In
accordance with ASC 350-20, goodwill will not be amortized but instead will be tested for impairment at least annually (more frequently if
certain indicators are present). In the event that management determines that the value of goodwill has become impaired, we will incur an
accounting charge for the amount of impairment during the fiscal quarter in which the determination is made.

Deferred income tax.    A preliminary estimate of $152,000 has been allocated to non-current deferred tax assets and $2.4 million has
been allocated to non-current deferred tax liabilities, which results primarily from the fair market value assigned to various assets including
intangibles, land, and building.

Contingent Earnout Obligation.    The Company is obligated to pay additional purchase consideration to the former shareholder of
Medix  if  certain  revenue  targets  are  met  in  2011  and  2012.  We  have  recorded  an  estimate  of  the  fair  value  of  the  contingent  earnout
obligation  based  on  future  revenue  projections  of  the  Medix  business  under  various  potential  scenarios  applying  weighted  probability
assumptions of their outcomes. Actual amounts paid may differ from the obligation recorded.

Alpine Biomed Holdings Corp.—We acquired Alpine Biomed Holdings Corp. (“Alpine Biomed”) on September 14, 2009 for $43.2
million in cash pursuant to an Agreement and Plan of Merger. Alpine Biomed, with corporate headquarters in Fountain Valley, California
and manufacturing facilities in Montreal, Canada, and Copenhagen, Denmark, is a leader in the development, manufacturing, and sales of
devices for the diagnosis of neurological disorders. Alpine Biomed’s broad range of products includes advanced electromyography systems
for the diagnoses of peripheral nervous system dysfunctions as well as devices for routine EEG and long term epilepsy monitoring. The
acquisition broadened our product offerings, primarily in electromyography and allows us to further leverage our existing sales channels
both in the United States and internationally.

During  2010  we  substantially  completed  a  reorganization  plan  adopted  in  January  2010  that  was  designed  to  eliminate  redundant
costs  resulting  from  our  acquisition  of Alpine  Biomed  and  to  improve  efficiencies  in  operations.  Under  the  plan, Alpine  operations  in
Fountain  Valley  were  moved  to  our  corporate  headquarters  in  San  Carlos,  California, Alpine’s  sales  organization  was  merged  into  the
Company’s  global  sales  organization,  and  Alpine  operations  in  Montreal,  Canada  were  transitioned  to  our  existing  Xltek  facility  in
Oakville, Ontario, Canada,.

We  acquired  all  outstanding  shares  of Alpine  Biomed  capital  stock  for  $43.2  million  in  cash. A  total  of  $345,000  of  direct  costs

associated with the acquisition was expensed as incurred and reported as a component of general and administrative expenses.

In  accordance  with ASC  805-10,  the  acquisition  has  been  accounted  for  as  a  purchase  business  combination.  Under  the  purchase
method  of  accounting,  the  assets  acquired  and  liabilities  assumed  from Alpine  Biomed  at  the  date  of  acquisition  are  recorded  in  the
consolidated  financial  statements  at  their  respective  fair  values  as  of  the  acquisition  date.  The  excess  of  the  purchase  price  over  the  fair
value  of  the  acquired  net  assets  has  been  recorded  as  goodwill  in  the  amount  of  $28.8  million.  This  goodwill  is  expected  to  be  non-
deductible for tax purposes. Alpine Biomed’s results of operations are included in the consolidated financial statements from the date of
the acquisition.

The Agreement  and  Plan  of  Merger  also  included  an  earnout  provision  based  on  the  achievement  of  a  certain  revenue  target  as  of

December 31, 2009, however, the revenue target was not achieved and no additional cash consideration was paid.

In  finalizing  the  purchase  price  allocation  during  2010,  we  recorded  adjustments  to  the  original  estimate  of  the  purchase  price
allocation of the fair value of the assets acquired and liabilities assumed that decreased the carrying amount of goodwill by $34,000, due to
adjustments to inventories, accounts payable, deferred taxes, and accrued expenses.

The  following  unaudited  pro  forma  combined  results  of  operations  of  Natus  for  the  twelve  months  ended  December  31,  2010  and

December 31, 2009, which includes the results of Alpine from the date of the acquisition.

Hawaii Medical—We  acquired  Hawaii  Medical,  LLC  (“Hawaii  Medical”)  on  July  2,  2009  pursuant  to  an Agreement  and  Plan  of
Merger. Massachusetts based Hawaii Medical manufactures and markets single-use disposable products sold into the NICU and nursery in
hospitals.  During  the  third  quarter  2009  we  transitioned  substantially  all  of  the  operations  of  Hawaii  Medical  to  our  Olympic  facility  in
Seattle, Washington.

We acquired all outstanding units of Hawaii Medical for $2.9 million in cash. In addition to the purchase price paid at closing, an
earnout  provision  of  the  purchase  agreement  may  result  in  additional  cash  consideration  depending  upon  the  achievement  of  certain
revenue targets over a 36 month period. Although there is no limit to the additional consideration that will be paid if the revenue targets are
exceeded, no contingent obligation was

recorded as there is significant uncertainty that the revenue targets will be achieved. As of December 31, 2010, the revenue targets were not
achieved.  We  also  incurred  $115,000  of  direct  costs  associated  with  the  acquisition  that  were  expensed  as  a  component  of  general  and
administrative expense in the third quarter 2009.

The  acquisition  has  been  accounted  for  as  a  purchase  business  combination.  Under  the  purchase  method  of  accounting,  the  assets
acquired  and  liabilities  assumed  from  Hawaii  Medical  at  the  date  of  acquisition  are  recorded  in  the  consolidated  financial  statements  at
their respective fair values as of the acquisition date. The excess of the purchase price over the fair value of the acquired net assets has
been  recorded  as  goodwill  in  the  amount  of  $2.4  million.  This  goodwill  is  expected  to  be  non-deductible  for  tax  purposes.  Hawaii
Medical’s results of operations are included in the consolidated financial statements from the date of the acquisition.

Years Ended December 31, 2010, 2009 and 2008

9— RESERVE FOR PRODUCT WARRANTIES

We provide a warranty on all medical device products that is generally one year in length. We also sell extended service agreements
on our medical device products. Service for domestic customers is provided by Company-owned service centers that perform all service,
repair and calibration services. Service for international customers is provided by a combination of Company-owned facilities and third-
party vendors on a contract basis.

We have accrued a warranty reserve, included in accrued liabilities on the accompanying balance sheets, for the expected future costs
of servicing products during the initial warranty period. We base the liability on actual warranty costs incurred to service those products.
On  new  products,  additions  to  the  reserve  are  based  on  a  combination  of  factors  including  the  percentage  of  service  department  labor
applied  to  warranty  repairs,  as  well  as  actual  service  department  costs,  and  other  judgments,  such  as  the  degree  to  which  the  product
incorporates  new  technology.  The  reserve  is  reduced  as  costs  are  incurred  to  honor  existing  warranty  obligations  or  when  current  facts
indicate that the original estimates of expected future costs of servicing products were overstated.

Detail of activity in product warranty reserve is as follows, (in thousands):

The  estimates  we  use  in  projecting  future  product  warranty  costs  may  prove  to  be  incorrect. Any  future  determination  that  our
product warranty reserves are understated could result in increases to our cost of sales and reductions in our operating profits and results of
operations.

10— STOCKHOLDERS’ EQUITY

Common Stock—We have 120,000,000 shares of common stock authorized at a par value or $0.001 per share. We issued 885,500
shares of our common stock in a registered offering  in April  2008  at  an  offering  price  of  $18.27  per  share,  raising  approximately  $15.2
million, net of underwriting fees and other costs. In May 2008, we issued 4,600,000 shares of our common stock in a registered offering at
an offering price of $19.50 per share, raising approximately $84.1 million, net of underwriting fees and other costs of the offering.

Preferred Stock—We have 10,000,000 shares of preferred stock authorized at a par value of $0.001 per share. In accordance with
the terms of the amended and restated certificate of incorporation, the Board of Directors is authorized to provide for the issuance of one or
more  series  of  preferred  stock,  including  increases  or  decreases  to  the  series.  The  Board  of  Directors  has  the  authority  to  set  the  rights,
preferences, and terms of such shares. As of December 31, 2010, no shares of preferred stock were issued and outstanding.

Stockholder Rights Plan—We  adopted  a  Stockholder  Rights  Plan  in  September  2002  (the  “Rights  Plan”)  that  was  amended  most
recently  in  September  2006.  Pursuant  to  the  Rights  Plan,  we  declared  a  dividend  of  one  Preferred  Stock  Purchase  Right  per  share  of
common stock (the “Rights”) and each such Right has an exercise price of $23.00. The Rights become exercisable, unless redeemed by the
Company, upon the occurrence of certain events, including the announcement of a tender offer or exchange offer for our common stock or
the acquisition of a specified percentage of the our common stock by a third party.

As of December 31, 2010, unrecognized compensation related to the unvested portion of our stock options and other stock awards

was approximately $8.5 million, which is expected to be recognized over a weighted average period of 2.6 years.

Stock Awards Plans—Our Amended and Restated 2000 Stock Awards Plan (the “Plan”) provides for the granting of the following:

•

•

•

•

•

  Incentive stock options to employees;

  Non-statutory stock options to employees, directors and consultants;

  Restricted stock awards and restricted stock units;

  Stock bonuses; and

  Stock appreciation rights.

As of December 31, 2010, there were 2,857,888 shares available for future awards under the Restated Plan.

Under  the  Plan,  stock  options  may  be  issued  at  not  less  than  the  fair  market  value  of  the  common  stock  on  the  date  of  grant,  as
determined  by  the  Board  of  Directors.  Options  issued  under  the  Plan  become  exercisable  as  determined  by  the  Board  of  Directors  and
expire  no  more  than  six  years  after  the  date  of  grant.  Most  options  vest  ratably  over  four  years.  Since  2005,  our  option  awards  have
consisted  solely  of  non-statutory  stock  options.  Stock  awards  are  typically  granted  to  existing  employees  once  a  year  at  the  time  of  the
Company’s annual shareholder meeting.

We also provide for grants of options to our nonemployee directors from the 2000 Director Stock Option Plan (the “Director Plan”)
that  have  similar  terms  to  those  options  granted  from  the  Plan,  except  that  such  options  vest  ratably  over  a  twelve  month  period. As  of
December 31, 2010 there were 511,142 shares available for future awards under the Director Plan.

We also have the 1991 Stock Option Plan and the 2000 Supplemental Stock Option Plan (the “Inactive Plans”) that have been closed
to new grants since July 20, 2001. Options outstanding under the Inactive Plans were generally governed by the same terms as those under
the 2000 Plan, except that the options expired no more than ten years after the date of grant. Options still outstanding under the Inactive
Plans remain outstanding pursuant to their original terms.

Cash received from option exercises for the years ended December 31, 2010 and 2009 was $1.7 million and $348,000, respectively.

Black-Scholes  Inputs—The  fair  value  of  option  grants  was  estimated  using  the  Black-Scholes  option  pricing  model  with  the

following weighted average assumptions:

Expected life in years
Risk free interest rate
Expected volatility
Expected forfeiture rate
Dividend yield

Years Ended December 31,
2009

2008

  2.8% 
37% 
  13.4% 
 None  

We  have  no  history  or  expectation  of  paying  dividends  on  our  common  stock.  All  options  are  treated  as  a  single  group  in  the
determination of expected life, as we do not currently expect substantially different exercise or post-vesting termination behavior among
our employee population. Prior to June 2006 we granted options that had a contractual term of 10 years. Subsequent to June 15, 2006, all
options granted by the Company have a contractual life of six years. Through December 31, 2007 we used the simplified method allowed
under Staff Accounting Bulletin No. 107 in determining the expected life of options. Beginning January 1, 2008 we adopted a method of
determining  the  expected  life  of  options  based  exclusively  on  historical  share  option  exercise  experience  of  our  employees  for  options
granted by the Company after June 15, 2006.

The risk-free interest rate is based on the U.S. Treasury yield for a term consistent with the expected life of the awards in effect at the

time of grant. Expected volatility is based exclusively on historical volatility data of our common stock.

Share-based compensation expense associated with options is based on awards ultimately expected to vest. At the time of an option
grant,  we  estimate  the  expected  future  rate  of  forfeitures  based  on  historical  experience.  These  estimates  are  revised,  if  necessary,  in
subsequent periods if actual forfeiture rates differ from those estimates. If the actual forfeiture rate is lower than estimated we will record
additional expense and if the actual forfeiture is higher than estimated we will record a recovery of prior expense.

Years Ended December 31, 2010, 2009 and 2008

The  fair  market  value  of  outstanding  restricted  stock  awards  at  December  31,  2010  was  $8.5  million.  The  weighted  average

remaining recognition period for unvested restricted stock awards at December 31, 2010 was 2.6 years.

The  aggregate  intrinsic  value  of  outstanding  restricted  stock  units  at  December  31,  2010  was  $1.0  million.  The  weighted  average

remaining recognition period for unvested restricted stock units at December 31, 2010 was 2.9 years.

Employee Stock Purchase Plan—The 2000 Employee Stock Purchase Plan (the “ESPP”) was adopted effective upon the closing of
our initial public offering. Under the ESPP, eligible employees can elect to have salary withholdings of up to 15% of the sum of their W-2
cash compensation and 401(k) contributions to a maximum of $12,500 per offering period, to purchase shares of common stock on April 30
and October 31 of each year. The purchase price for shares acquired under the ESPP is 85% of the fair market value on the last day of the
offering period. As of December 31, 2010, there were 4,212,387 shares reserved for future issuance under the ESPP.

Because the ESPP does not have a “look back” feature, the compensation expense associated with the Plan is not measured by the use
of the Black-Scholes pricing model, but rather by measuring the difference between the fair market value of our common stock on the last
day of the offering period and the purchase price for the offering period, which is 85% of the fair market value. Compensation expense
associated with the ESPP for the years ended December 31, 2010, 2009 and 2008, respectively, was $133,000, $108,000 and $87,000.

Cash  received  from  purchases  under  the  ESPP  for  the  years  ended  December  31,  2010,  2009  and  2008,  respectively,  was

approximately $866,000, $729,000 and $548,000.

12— RESTRUCTURING RESERVE

In January 2010, we adopted a reorganization plan (the “Restructuring Plan”) that is designed to eliminate redundant costs resulting
from our acquisition of Alpine Biomed and to improve efficiencies in operations. Under the plan, which was substantially completed in the
first half of 2010, Alpine operations in Montreal, Canada were transitioned to our existing Xltek facility in Oakville, Ontario, Canada, and
Alpine’s sales organization was merged into our global sales organization.

The Restructuring Plan resulted in a staff reduction of approximately 70 employees for which we recorded a restructuring charge for
severance benefits of approximately $3.0 million during the first fiscal quarter of 2010, which was reduced by $268,000 during the second
fiscal  quarter.  In  addition,  during  the  second  fiscal  quarter  of  2010  we  recorded  a  $300,000  charge  for  a  lease  termination  fee.  We  also
recorded a $44,000 charge to write off property and equipment.

We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities
for  the  expected  future  tax  consequences  of  events  that  have  been  included  in  the  financial  statements.  Under  this  method,  deferred  tax
assets and liabilities are determined based on the differences between the financial statements and tax basis of assets and liabilities using
enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax
assets and liabilities is recognized in income in the period that includes the enactment date.

We  record  net  deferred  tax  assets  to  the  extent  we  believe  these  assets  will  more  likely  than  not  be  realized.  In  making  such
determination,  we  consider  all  available  positive  and  negative  evidence,  including  future  reversals  of  existing  taxable  temporary
differences, projected future taxable income, tax planning strategies and recent financial operations. In the event we were to determine that
we  would  be  able  to  realize  our  deferred  income  tax  assets  in  the  future  in  excess  of  their  net  recorded  amount,  we  would  make  an
adjustment to the valuation allowance which would reduce the provision for income taxes.

At  December  31,  2010  we  had  total  U.S.  federal  net  operating  loss  carryforwards  of  approximately  $4.6  million  and  state  net
operating loss carryforwards of approximately $2.0 million, available to reduce future taxable income. The federal and state net operating
loss carryforwards, if not utilized to offset taxable income in future periods, will expire in various amounts beginning in 2021 and 2015,
respectively.

At  December  31,  2010,  we  had  foreign  net  operating  losses  of  $3.7  million  and  $8.1  million  from  Deltamed  and Alpine  Biomed,
respectively. Alpine  Biomed’s  net  operating  loss  carryforwards,  if  not  utilized  to  offset  taxable  income  in  future  periods,  will  expire  in
various amounts beginning in 2028. In addition, Alpine has investment tax credits of approximately $147,000 which will expire in various
amounts  beginning  in  2022. At  December  31,  2010,  Xltek  has  investment  tax  credits  of  approximately  $549,000  which  will  expire  in
various amounts beginning in 2012.

The extent to which the federal operating loss and tax credit carryforwards can be used to offset future taxable income may be limited,
depending on the extent of ownership changes within any three-year period, as provided in the Tax Reform Act of 1986. Such a limitation
could result in the expiration of carryforwards before they are utilized.

A  valuation  allowance  is  provided  when  it  is  more  likely  than  not  that  some  portion  or  all  of  the  deferred  tax  assets  will  not  be
realized. Accordingly, valuation allowances of $5.7 million and $5.8 million were recorded during the years ended December 31, 2010 and
2009, respectively.

We receive tax deductions from the gains realized by employees on the exercise of certain non-qualified stock options for which the
benefit is recognized as a component of stockholders’ equity. In 2010 we recorded approximately $551,000 of additional paid in capital
related to exercises of non-qualified stock options by employees.

We have not provided for U.S. federal income and foreign withholding taxes on undistributed earnings from non-U.S. operations as of
December 31, 2010 because such earnings are intended to be reinvested indefinitely. As of December 31, 2010, the amount of undistributed
earnings from non-U.S. operations has not been estimated as the determination is not practicable.

Uncertain Tax Positions—We account for uncertain tax positions in accordance with ASC 740-10-05,  Accounting for Income Taxes
– an interpretation of FASB Statement 109 . This interpretation establishes the criteria that must be met prior to recognition of the financial
statement benefit of a position taken in a tax return

and is based on a benefit-recognition model. Provided that the tax position is deemed more likely than not of being sustained, we recognize
the  largest  amount  of  tax  benefit  that  is  greater  than  50  percent  likely  of  being  ultimately  realized  upon  settlement.  The  tax  position  is
derecognized when it is no longer more likely than not of being sustained.

A reconciliation of the beginning and ending amount of unrecognized tax benefits (excluding interest and penalties) is as follows (in

thousands):

Balance at January 1, 2008

Additions for tax positions related to the current year
Lapse of statutes of limitations

(145) 
$5,486  

The unrecognized tax benefits of $5.5 million include $2.5 million of uncertain tax positions that would impact our effective tax rate

if recognized.

At  December  31,  2010  and  2009,  we  had  cumulatively  accrued  approximately  $932,000  and  $647,000  for  estimated  interest  and
penalties related to uncertain tax positions. We record interest and penalties related to unrecognized tax positions as a component of income
tax expense, which totaled approximately $285,000 and $161,000 for the 12 months ended December 31, 2009 and 2008, respectively.

We  are  currently  unaware  of  any  uncertain  tax  positions  that  could  result  in  significant  additional  payments,  accruals,  or  other

material deviation in this estimate over the next 12 months.

Our tax returns remain open to examination as follows: U.S. federal, 2006 through 2010; U.S. states, generally 2005 through 2010;

significant foreign jurisdictions, generally 2007 through 2010.

15— EMPLOYEE BENEFIT PLAN

We have a 401(k) tax-deferred savings plan under which eligible U.S. employees may elect to have a portion of their salary deferred
and contributed to the plan. Employer matching contributions are determined by management and are discretionary. Employer matching
contributions were approximately $492,000, $455,000 and $467,000, respectively, in the years ended December 31, 2010, 2009, and 2008.
For new hires, employer contributions vest ratably over the first two years of employment.

16— SEGMENT, CUSTOMER, AND GEOGRAPHIC INFORMATION

We  operate  in  one  reportable  segment  in  which  we  provide  healthcare  products  used  for  the  screening,  detection,  treatment,
monitoring  and  tracking  of  common  medical  ailments  in  newborn  care,  hearing  impairment,  neurological  dysfunction,  epilepsy,  sleep
disorders, and balance and mobility disorders.

financial measurements, and provides for events of default, including failure to pay any interest when due, failure to perform or observe
covenants,  bankruptcy  or  insolvency  events  and  the  occurrence  of  a  material  adverse  effect.  We  have  granted  Wells  Fargo  a  security
interest in all of the assets of the Company. The credit facility contains covenants including minimum EBITDA, quick ratio, and a leverage
ratio. We did not draw on the facility during 2010. We have no other significant credit facilities.

18— COMMITMENTS AND CONTINGENCIES

Leases  –  We  have  entered  into  noncancelable  operating  leases  for  some  of  our  facilities  located  in  the  U.S.  and  Europe  through

October 2016. Minimum lease payments under noncancelable operating leases as of December 31, 2010 are as follows (in thousands):

Rent expense, which is recorded on the straight-line method from commencement over the period of the lease, totaled $1,971,000,

$2,140,000 and $1,805,000 in 2010, 2009 and 2008, respectively.

Purchase commitments—We had various firm purchase commitments for inventory totaling $15.7 million at December 31, 2010.

Indemnifications—Under  our  bylaws,  we  have  agreed  to  indemnify  our  officers  and  directors  for  certain  events  or  occurrences
arising as a result of the officer or director serving in such capacity. We have a director and officer liability insurance policy that limits our
exposure under these indemnifications and enables us to recover a portion of any future loss arising out of them. In addition, we enter into
indemnification agreements with other parties in the ordinary course of business. We have determined that these agreements fall within the
scope  of ASC  460,  Guarantees. In some cases we have obtained liability insurance providing coverage that limits its exposure for these
other  indemnified  matters.  We  have  not  incurred  material  costs  to  defend  lawsuits  or  settle  claims  related  to  these  indemnification
agreements. We believe the estimated fair value of these indemnification agreements is minimal and have not recorded a liability for these
agreements as of December 31, 2010.

Legal matters—We may from time to time become a party to various legal proceedings or claims that arise in the ordinary course of
business.  We  do  not  believe  that  any  current  legal  or  administrative  proceedings  are  likely  to  have  a  materially  adverse  effect  on  our
business, financial condition, or results of operations.

markets that are not active or for which all significant inputs are observable, either directly or indirectly. Bank money market accounts have
a net asset value of $1.00 per share and consist principally of commercial paper with a rating of A-1/A-1+. Level 3 valuations are based on
inputs that are not unobservable and significant to the overall fair value measurement.

20— IMMATERIAL CORRECTIONS TO PRIOR PERIOD FINANCIAL STATEMENTS

Subsequent  to  the  issuance  of  our  consolidated  financial  statements  for  the  year  ended  December  31,  2009  we  discovered  certain
errors relating primarily to the amount of manufacturing labor and overhead applied to inventory. As a result, certain previously reported
amounts  included  in  the  accompanying  consolidated  financial  statements  have  been  restated  to  reflect  the  correction  of  the  errors.  We
believe the effects of the errors are not material to our consolidated financial statements. In addition, certain other corrections previously
identified that are not material individually or in the aggregate have also been corrected related to accrued sales commissions, the amount
of revenue deferred under multiple deliverable revenue arrangements, and reclassification from accrued liabilities to accounts payable.

(iii) Thresholds  for  Company  Gross  Revenue.  The  threshold  amount  for  payment  of  the  Earnout  Amounts  (except  for  the
Supplemental  Earnout Amount)  based  on  Company  Gross  Revenue  shall  be  U.S.  $37,772,000  for  the  First  Earnout  Period  (the  “First
Company  Gross  Revenue  Threshold”)  and  U.S.  $38,976,000  for  the  Second  Earnout  Period  (the  “Second  Company  Gross  Revenue
Threshold”, and together with the First Company Gross Revenue Threshold, the “Company Gross Revenue Thresholds”).  The  threshold
amount  for  payment  of  the  Supplemental  Earnout Amount  based  on  Company  Gross  Revenue  shall  be  U.S.  $30,000,000  for  the  First
Earnout Period (the “Supplemental Earnout Threshold”).

(iv) (A) Earnout Amount for the First Earnout Period. Natus shall pay the First Earnout Amount to the Selling Shareholders in
accordance with their respective pro rata share if (i) the amount of Forecasted Sales for the First Earnout Period is equal to or greater than
the First Forecasted Sales Threshold or (ii) the amount of Company Gross Revenue for the First Earnout Period is equal to or

6

 
greater than the First Company Gross Revenue Threshold. Such payment shall be made on the First Earnout Payment Date, unless Natus
delivers  on  or  before  the  First  Earnout  Payment  Date  an  Earnout  Certificate  (as  defined  in  clause  (vi)  of  this Section  2.01(c))  to  the
Shareholders’ Agent containing amounts of Forecasted Sales and Company Gross Revenue that do not equal or exceed the thresholds set
forth in clauses (ii) or (iii) of this Section 2.01(c), as applicable, for the First Earnout Period, in which case payment shall be made within
three  Business  Days  of  the  parties’  resolution  of  any  objection  of  the  Shareholders’ Agent  to  the  amounts  of  Forecasted  Sales  and/or
Company Gross Revenue as set forth in the Earnout Certificate pursuant to the procedures set forth in Section 2.01(c)(vi) and (xii) below if
such resolution concludes that Forecasted Sales and/or Company Gross Revenue equals or exceeds the thresholds set forth in clauses (ii) or
(iii) of this Section 2.01(c), as applicable, for the First Earnout Period. For the avoidance of any doubt, if for whatever reason Natus fails to
deliver the Earnout Certificate for the First Earnout Period on or before December 20, 2011, the Shareholders’ Agent shall deliver to Natus
in  writing  a  default  notice,  providing  Natus  an  additional  15-day  term  to  deliver  the  Earnout  Certificate.  If  such  additional  15-day  term
expires without Natus delivering the Earnout Certificate, Natus shall forthwith pay the First Earnout Amount to the Selling Shareholders in
accordance with their respective pro rata share irrespective of the achievement or not of the thresholds set forth in clauses (ii) or (iii) of this
Section 2.01(c), as applicable, for the First Earnout Period. Any portion of the First Earnout Amount due to the Selling Shareholders under
this Agreement which is not paid when due shall bear the Default Interest.

(B) Payment  of  the  Supplemental  Earnout Amount .  Natus  shall  pay  the  Supplemental  Earnout Amount  to  the  Selling
Shareholders in accordance with their respective pro rata share if the amount of Company Gross Revenue for the First Earnout Period is
equal to or greater than the Supplemental Earnout Threshold. Such payment shall be made on the First Earnout Payment Date, unless Natus
delivers on or before the First Earnout Payment Date an Earnout Certificate to the Shareholders’ Agent containing amounts of Company
Gross  Revenues  that  do  not  equal  or  exceed  the  Supplemental  Earnout  Threshold,  in  which  case  payment  shall  be  made  within  three
Business  Days  of  the  parties’  resolution  of  any  objection  of  the  Shareholders’ Agent  to  the  amounts  of  Company  Gross  Revenue  as  set
forth  in  the  Earnout  Certificate  pursuant  to  the  procedures  set  forth  in  Section  2.01(c)(vi)  and  (xii)  if  such  resolution  concludes  that  the
Company Gross Revenue equals or exceeds the Supplemental Earnout Threshold. For the avoidance of any doubt, if for whatever reason
Natus fails to deliver the Earnout Certificate for the First Earnout Period on or before December 20, 2011, the Shareholders’ Agent shall
deliver to Natus in writing a default notice, providing Natus an additional 15-day term to deliver the Earnout Certificate. If such additional
15-day term expires without Natus delivering the Earnout Certificate, Natus shall forthwith pay the Supplemental Earnout Amount to the
Selling Shareholders in accordance with their respective pro rata share irrespective of the achievement or not of the Supplemental Earnout
Threshold. Any portion of the Supplemental Earnout Amount due to the Selling Shareholders under this Agreement which is not paid when
due shall bear the Default Interest.

(v) Earnout Amount for the Second Earnout Period. Natus shall pay the Second Earnout Amount to the Selling Shareholders in
accordance with their respective pro rata share if (i) the amount of Forecasted Sales for the Second Earnout Period is equal to or greater
than the Second Forecasted Sales Threshold or (ii) the amount of Company Gross Revenue for the Second Earnout Period is equal to or
greater than the Second Company Gross Revenue Threshold. Such payment shall be made on the Second Earnout Payment Date, unless
Natus delivers on or before the Second Earnout Payment Date an Earnout Certificate (as defined in clause (vi) of this Section 2.01(c)) to the
Shareholders’ Agent  containing  an  amount  of  either  Forecasted  Sales  or  Company  Gross  Revenue  that  does  not  equal  or  exceeds  the
thresholds set forth in clauses (ii) or (iii) of this Section 2.01(c), as applicable, for the Second Earnout Period, in which case payment shall
be made within three Business Days of the parties’ resolution of any objection of the Shareholders’ Agent to the amounts of Forecasted
Sales or Company Gross Revenue as set forth in the Earnout Certificate pursuant to the procedures set forth in Section

7

 
2.01(c)(vi)  and  (xii)  below  if  such  resolution  concludes  that  either  Forecasted  Sales  or  Company  Gross  Revenue  equals  or  exceeds  the
thresholds set forth in clauses (ii) or (iii) of this Section 2.01(c), as applicable, for the Second Earnout Period. For the avoidance of any
doubt, if for whatever reason Natus fails to deliver the Earnout Certificate for the Second Earnout Period on or before December 20, 2012,
the Shareholders’ Agent shall deliver to Natus in writing a default notice, providing Natus an additional 15-day term to deliver the Earnout
Certificate. If such additional 15-day term expires without Natus delivering the Earnout Certificate, Natus shall forthwith pay the Second
Earnout Amount to the Selling Shareholders in accordance with their respective pro rata share irrespective of the achievement or not of the
thresholds set forth in clauses (ii) or (iii) of this Section 2.01(c), as applicable, for the Second Earnout Period. Any portion of the Second
Earnout Amount due to the Selling Shareholders under this Agreement which is not paid when due shall bear the Default Interest.

(vi) Payments; Review of Books and Records. For any payments due to the Selling Shareholders pursuant to clauses (iv) and
(v) above, Natus shall pay each Selling Shareholder its pro rata share of the applicable Earnout Amount, if any, as indicated in  Schedule I –
Part B, by wire transfer of immediately available same day funds to the bank accounts with U.S. banks as indicated in Schedule I – Part C.
On or before the First Earnout Payment Date, with respect to the First Earnout Period, or on or before the Second Earnout Payment Date,
with respect to the Second Earnout Period, Natus shall deliver, or shall cause the Company to deliver, to the Shareholders’ Agent on behalf
of the Selling Shareholders a certificate of the Chief Financial Officer, Treasurer or Controller of Natus or a duly authorized officer of the
Company certifying in reasonable detail the amount of Forecasted Sales and Company Gross Revenue for the applicable Earnout Period
and,  if  applicable,  any  adjustments  to  the  thresholds  set  forth  in  clauses  (ii)  or  (iii)  of  this  Section  2.01(c)  as  per  clause  (xi)  of  this
Section 2.01(c) (the “Earnout Certificate”). The Earnout Certificate shall contain a description of the Forecasted Sales for each client of the
Company  detailing  the  amount  and  date  of  each  sale.  If  the  Earnout  Certificate  indicates  that  no  Earnout Amount  is  payable  for  the
applicable Earnout Period, then the Shareholders’ Agent shall have the right to review the relevant books and records of the Company to
verify  or  challenge  the  Forecasted  Sales  and  Company  Gross  Revenue  set  forth  in  the  applicable  Earnout  Certificate  for  the  applicable
Earnout Period and, if applicable, any adjustments to the thresholds set forth in clauses (ii) or (iii) of this Section 2.01(c) as per clause (xi) of
this Section 2.01(c), provided that the Shareholders’ Agent shall provide written notice to Natus of its intent to exercise such right within 30
days of the receipt of the Earnout Certificate for such applicable Earnout Period. If the Shareholders’ Agent provides such notice, Natus
shall, and shall cause the Company to, grant the Shareholders’ Agent (together with a reasonable number of its appointed advisors) access
to  the  Company’s  books  and  records  of  the  Company  during  normal  business  hours  and  with  3-day  advance  notice  as  requested  by  the
Shareholders’ Agent for the purpose of such review, and such review shall be completed within 60 days from the date of the Shareholders’
Agent’s notice of the intent to conduct such review. If following such review the Shareholders’ Agent disagrees with Natus on behalf of the
Selling Shareholders as to the amount of either Forecasted Sales or Company Gross Revenue

8

 
for the applicable Earnout Period and, if applicable, any adjustments to the thresholds set forth in clauses (ii) or (iii) of this Section 2.01(c)
as per clause (xi) of this Section 2.01(c), the Shareholders’ Agent shall provide written notice in reasonable detail to Natus of its objections
to the calculations of such amounts, which must be delivered not later than 65 days from the date of the Shareholders’ Agent’s notice to
Natus  of  the  intent  to  conduct  the  review  of  Forecasted  Sales  or  Company  Gross  Revenue  for  the  applicable  Earnout  Period  and,  if
applicable, any adjustments to the thresholds set forth in clauses (ii) or (iii) of this Section 2.01(c) as per clause (xi) of this Section 2.01(c)
(the “Earnout Objection Deadline Date”), then such disagreement or dispute shall be determined in accordance with Section 2.01(c)(xii) of
this Agreement. The parties intend, for tax purposes, that the payments set forth in clauses (iv) and (v) above qualify for installment sale
treatment under applicable Tax Law. Such payments shall be treated as imputed interest to the extent required by applicable Tax Law. If
upon resolution of objections of the Shareholders’ Agent in accordance with Section 2.01(c)(xii), Natus and Shareholders’ Agent agree, or
the  Earnout  Expert Accountant  determines,  that  the  amount  of  Forecasted  Sales  or  Company  Gross  Revenue  for  the  applicable  Earnout
Period  equals  or  exceeds  the  applicable  Forecasted  Sales  Threshold  or  Company  Gross  Revenue  Threshold  or  Supplemental  Earnout
Threshold (taking into consideration, if applicable, any adjustments to the thresholds set forth in clauses (ii) or (iii) of this Section 2.01(c) as
per  clause  (xi)  of  this  Section  2.01(c)),  then  within  three  (3)  Business  Days  of  such  agreement  or  determination  Natus  shall  pay  each
Selling Shareholder its pro rata share of the applicable Earnout Amount, as indicated in Schedule I – Part B, by wire transfer of immediately
available same day funds to the bank accounts with U.S. banks as indicated in Schedule I – Part C. Any portion of the applicable Earnout
Amount due to the Selling Shareholders under this Agreement which is not paid when due shall bear the Default Interest.

(vii) No  Carry-over.  Subject  to  Section  2.01(c)(xi),  if  no  Earnout Amount  is  paid  for  the  First  Earnout  Period  because  the
amount  of  Forecasted  Sales  for  such  Earnout  Period  did  not  equal  or  exceeded  the  First  Forecasted  Sales  Threshold  and  the  amount  of
Company  Gross  Revenue  for  such  Earnout  Period  did  not  equal  or  exceeded  the  First  Company  Gross  Revenue  Threshold  (taking  into
consideration,  if  applicable,  any  adjustments  to  such  thresholds  as  per  clause  (xi)  of  this  Section  2.01(c)),  then  the  Selling  Shareholders
shall have no right to carry-over and apply any amount of Forecasted Sales or Company Gross Revenue from the First Earnout Period to
the Second Earnout Period in order to earn payment of the Second Earnout Amount.

(viii) Forecasted  Sales.  For  purposes  of  this Agreement,  “Forecasted  Sales”  for  any  Earnout  Period  shall  be  the  aggregate
amount  of  sales  (including,  without  limitation,  Drawback  and  Fiscal  Bonus  applicable  (including  retroactively)  to  the  relevant  Earnout
Period), as determined in accordance with GAAP as consistently applied by the Company in its audited annual financial statements for the
fiscal years ended on October 31, 2008 and October 31, 2009, from sales of the Earnout Products and Services by the Company for the
Venezuelan market in the applicable Earnout Period. For purposes of calculating Forecasted Sales to be expressed in US$ in determining
whether  the  Forecasted  Sales  Thresholds  for  the  applicable  Earnout  Period  have  been  met,  any  amount  of  sales  which  is  not  already
recorded in US$ by the Company shall be converted and translated from the corresponding currency into US$ as follows: (A) using the
average of the closing spot exchange rates published by Banco de la Nación Argentina for the corresponding currency into US$ for each
Business  Day  of  each  particular  month,  calculate  the  average  exchange  rate  of  the  corresponding  currency  into  US$  in  effect  for  such
particular  month,  and  (B)  convert  monthly  revenue  in  the  corresponding  currency  into  US$  using  the  average  monthly  exchange  rate  in
effect for that month (hereinafter referred to as the “Exchange Rate Convention”). For the sake of clarity, the parties acknowledge that sales
of Earnout Products and Services by the Company do not include any royalties received by the Company from MASA under the MASA
Distribution Agreement (as defined in Section 2.03).

(ix) Company Gross Revenue. For purposes of this Agreement, “Company Gross Revenue” for any Earnout Period shall
be the aggregate amount of gross revenue (including, without limitation, Drawback and Fiscal Bonus applicable (including retroactively) to
the  relevant  Earnout  Period),  as  determined  in  accordance  with  GAAP  as  consistently  applied  by  the  Company  in  its  audited  annual
financial statements for the fiscal years ended on October 31, 2008 and October 31, 2009, from sales of the Earnout Products and Services
by  the  Company  in  the  applicable  Earnout  Period,  including,  without  limitation,  sales  to  the Argentine  market  and  any  and  all  foreign
markets. For purposes of calculating Company Gross Revenue to be expressed in US$ in determining whether the Company

9

 
Gross Revenue Thresholds for the applicable Earnout Period have been met, the amount of sales which is not already recorded in US$ by
the  Company  shall  be  converted  and  translated  into  US$  in  accordance  with  the  Exchange  Rate  Convention.  For  the  sake  of  clarity,  the
parties acknowledge that sales of Earnout Products and Services by the Company do not include any royalties received by the Company
from MASA under the MASA Distribution Agreement (as defined in Section 2.03).

(x) Earnout Products and Services. For purposes of this Agreement, “Earnout Product and Services” shall mean any of
the  products  and  services  at  any  time  produced,  manufactured,  marketed,  licensed,  sold,  distributed  or  otherwise  commercialized  by  the
Company (including, for the sake of clarification, from and after the Closing Date) (“Products and Services”).

(xi) Management of Business. Natus and each of the Selling Shareholders acknowledges and agrees that Natus shall have
sole  and  absolute  discretion  in  the  ordinary  course  of  its  business  and  consistent  with  its  past  practice  over  all  matters  relating  to  any
Earnout Product and Services from and after the Closing Date, including, but not limited to, any matter relating to the development, testing,
regulatory submission or regulatory approval, if applicable, manufacturing, marketing, sales, distribution, pricing, service or maintenance
thereof, and that Natus has no duty to take any action with regard to the sales of Earnout Product and Services from and after the Closing
Date; provided, however, that Natus acknowledges and agrees that (x) it shall not take any action or omit to take an action with the primary
purpose of seeking to avoid the payment of any Earnout Amount and (y) the thresholds set forth in clauses (ii) or (iii) of this Section 2.01(c)
shall be proportionally reduced to neutralize the negative impact, if any such actions of Natus affects the payment of any Earnout Amount.

(xii) Disagreements  over  Calculation  of  Earnout  Amount.  If  the  Shareholders’  Agent  on  behalf  of  the  Selling
Shareholders has provided notice to Natus on or before the Earnout Objection Deadline Date of its disagreement with the calculation of the
amount  of  Forecasted  Sales  or  Company  Gross  Revenue  for  an  Earnout  Period  as  set  forth  in  the  relevant  Earnout  Certificate,  such
disagreement shall be resolved as follows:

(A) Natus and the Shareholders’ Agent shall first use reasonable efforts to resolve the Shareholders Agent’s objections to

Natus’ calculations of the Forecasted Sales or Company Gross Revenue for the relevant period.

(B) If Natus and the Shareholders’ Agent do not reach a resolution of all objections set forth on the Shareholders’ Agent’s

statement of objections within 30 days after the delivery of such statement of objections as provided in clause (vi) of this
Section 2.01(c), the Shareholders’ Agent shall, within 30 days following the expiration of such 30-day period, submit the dispute to an
Earnout Expert Accountant (as defined below) to resolve any remaining objections set forth on the Shareholders’ Agent’s statement of
objections (the “Earnout Unresolved Objections”), and always in accordance with GAAP, as consistently applied by the Company in its
audited annual financial statements for the fiscal years ended on October 31, 2008 and October 31, 2009. “Earnout Expert Accountant”
shall mean an Argentine accounting firm designated by the Shareholders’ Agent among: Ernst & Young, PriceWaterhouse Coopers, or
KPMG, or if for any reason they are not able to act, the Earnout Expert Accountant shall be an Argentine accounting firm agreed
between the parties, in the understanding that any such accountant (and its affiliates) (other than Deloitte & Touche and the three
expressly named in this paragraph) so selected has not performed services for Natus, the Company, the Shareholders’ Agent or any of
the Selling Shareholders in the previous five years.

(C) Each of Natus and the Shareholders’ Agent shall submit to the Earnout Expert Accountant, within 15 days after the date

of the engagement of the Earnout Expert

10

 
Accountant (as evidenced by the date of the engagement agreement), a copy of the Earnout Certificate for the applicable Earnout
Period, a copy of the statement of objections delivered by the Shareholders’ Agent to Natus, and a statement setting forth the resolution
of any objections agreed to by Natus and the Shareholders’ Agent. Each of Natus and the Shareholders’ Agent shall submit to the
Earnout Expert Accountant (with a copy delivered to the other party on the same day), within 45 days after the date of the engagement
of the Earnout Expert Accountant, a memorandum (which may include supporting exhibits) setting forth their respective positions on
the Earnout Unresolved Objections. Each of Natus and the Shareholders’ Agent may (but shall not be required to) submit to the
Earnout Expert Accountant (with a copy delivered to the other party on the same day), within 60 days after the date of the engagement
of the Earnout Expert Accountant, a memorandum responding to the initial memorandum submitted to the Earnout Expert Accountant
by the other party. Unless expressly requested in writing by the Earnout Expert Accountant in a request made known to both Natus and
the Shareholders’ Agent, neither party may present any additional information or arguments to the Earnout Expert Accountant, either
orally or in writing.

(D) Within 90 days after the date of its engagement hereunder, the Earnout Expert Accountant shall issue an opinion which
shall include a determination of the Forecasted Sales and Company Gross Revenue for the applicable Earnout Period, giving effect to
any resolutions to objections agreed upon by Natus and the Shareholders’ Agent and to the Earnout Expert Accountant’s opinion on the
Earnout Unresolved Objections. Such determination of Forecasted Sales or Company Gross Revenue for such Earnout Period shall be
deemed to be final.

(E) The opinion by the Earnout Expert Accountant of the Earnout Unresolved Objections shall be conclusive and binding
upon Natus and the Shareholders’ Agent. Natus and the Shareholders’ Agent agree that the procedure set forth in this Section 2.01(c)
(xii) for resolving disputes with respect to the payout of any Earnout Amounts for the relevant Earnout Period shall be the sole and
exclusive method for resolving any such disputes; provided that this provision shall not prohibit either party from (i) instituting
litigation to enforce the opinion of the Earnout Expert Accountant or (ii) submitting the matter to arbitration as per Article IX of this
Agreement in case the Earnout Expert Accountant rejects to consider whether the thresholds set forth in clauses (ii) or (iii) of this
Section 2.01(c) have been reduced as per Section 2.01(c)(xi).

(F) The fees and expenses of the Earnout Expert Accountant shall be borne by the non prevailing party (and to the extent
that the Selling Shareholders are the non prevailing party, Natus and the Shareholders’ Agent at Natus request may cause the Escrow
Agent to deduct such fees and expenses of the Earnout Expert Accountant from the Escrow Cash and to pay such amount to Natus). For
such purpose, the written decision of the Earnout Expert Accountant shall set forth which was the prevailing party.

SECTION  2.02 Purchase  Price  Adjustment .  (a)  The  Purchase  Price  shall  be  subject  to  adjustment  on  the  following  terms  and

conditions:

Within 90 days after the Closing Date, Natus shall prepare and deliver to the Shareholders’ Agent the Draft Closing Balance Sheet,

which shall set forth the proposed Final Net Working Capital amount.

(ii) The Shareholders’ Agent shall deliver to Natus, within sixty (60) days after the date of delivery by Natus to the Shareholders’
Agent  of  the  Draft  Closing  Balance  Sheet  (the  “Objection  Deadline  Date”),  either  a  notice  indicating  that  the  Shareholders’ Agent
accepts  the  Draft  Closing  Balance  Sheet  or  a  statement  describing  in  reasonable  detail  its  objections  (if  any)  to  the  Draft  Closing
Balance Sheet. For the purpuses of allowing the Shareholders’ Agent to

11

 
prepare  such  detailed  statement,  Natus  shall  grant,  and  shall  cause  the  Company  to  grant,  at  the  Shareholders’ Agent  reasonably
request,  access  to  the  Company’s  accounting  books  and  records  by  the  Shareholders’ Agent  (together  with  a  reasonable  number  of
appointed  advisors).  If  the  Shareholders’  Agent  delivers  to  Natus  a  notice  accepting  the  Draft  Closing  Balance  Sheet,  or  the
Shareholders’ Agent  does  not  deliver  a  written  objection  to  the  Draft  Closing  Balance  Sheet  by  the  Objection  Deadline  Date,  then,
effective as of either the date of delivery of such notice of acceptance or as of the close of business (6 p.m. Buenos Aires time) on the
Objection Deadline Date, the Draft Closing Balance Sheet shall be deemed to be the Final Closing Balance Sheet. If the Shareholders’
Agent timely objects to the Draft Closing Balance Sheet, such objections shall be resolved as follows:

(A) Natus and the Shareholders’ Agent shall first use reasonable efforts to resolve such objections.

(B) If Natus and the Shareholders’ Agent do not reach a resolution of all objections set forth on the Shareholders’ Agent’s
statement of objections within 30 days after delivery of such statement of objections, the Shareholders’ Agent shall, within 30
days  following  the  expiration  of  such  30-day  period,  submit  the  dispute  to  an Arbitrating Accountant  (as  defined  below)  to
resolve any remaining objections set forth on the Shareholders’ Agent’s statement of objections (the “ Unresolved Objections”),
and always in accordance with GAAP, as consistently applied by the Company in its audited annual financial statements for the
fiscal years ended on October 31, 2008 and October 31, 2009. “Arbitrating Accountant” shall mean an Argentine accounting firm
designated by Natus among Ernst & Young, PriceWaterhouse Coopers, or KPMG, or if for any reason they are not able to act, the
Arbitrating Accountant shall be an Argentine accounting firm agreed between the parties, with the understanding that any such
accountant  (and  its  affiliates)  (other  than  Deloitte  &  Touche  the  three  expressly  named  in  this  paragraph)  so  selected  has  not
performed  services  for  Natus,  the  Company,  the  Shareholders’ Agent  or  any  of  the  Selling  Shareholders  in  the  previous  five
years.

(C) Each of Natus and the Shareholders’ Agent shall submit to the Arbitrating Accountant, within 10 days after the date of
the engagement of the Arbitrating Accountant (as evidenced by the date of the engagement agreement), a copy of the Preliminary
Balance Sheet and the Draft Closing Balance Sheet, a copy of the statement of objections delivered by the Shareholders’ Agent to
Natus,  and  a  statement  setting  forth  the  resolution  of  any  objections  agreed  to  by  Natus  and  the  Shareholders’ Agent.  Each  of
Natus and the Shareholders’ Agent shall submit to the Arbitrating Accountant (with a copy delivered to the other party on the
same day), within 45 days after the date of the engagement of the Arbitrating Accountant, a memorandum (which may include
supporting exhibits) setting forth their respective positions on the Unresolved Objections. Each of Natus and the Shareholders’
Agent may (but shall not be required to) submit to the Arbitrating Accountant (with a copy delivered to the other party on the
same day), within 15 days after the date of filing of the initial memorandum of the other party, a memorandum responding to the
initial  memorandum  submitted  to  the Arbitrating Accountant  by  the  other  party.  Unless  expressly  requested  in  writing  by  the
Arbitrating Accountant  in  a  request  made  known  to  both  Natus  and  the  Shareholders’ Agent,  neither  party  may  present  any
additional information or arguments to the Arbitrating Accountant, either orally or in writing.

(D) Within 90 days after the date of its engagement hereunder, the Arbitrating Accountant shall issue an opinion which shall

include a balance sheet,

12

 
comprised of the Draft Closing Balance Sheet as adjusted pursuant to any resolutions to objections agreed upon by Natus and the
Shareholders’ Agent  and  pursuant  to  the Arbitrating Accountant’s  opinion  on  the  Unresolved  Objections.  Such  balance  sheet
shall be deemed to be the Final Closing Balance Sheet.

(E) The opinion by the Arbitrating Accountant of the Unresolved Objections shall be conclusive and binding upon Natus
and  the  Shareholders’  Agent.  Natus  and  the  Shareholders’  Agent  agree  that  the  procedure  set  forth  in  this  Section  2.02  for
resolving disputes with respect to the Draft Closing Balance Sheet shall be the sole and exclusive method for resolving any such
disputes;  provided  that  this  provision  shall  not  prohibit  either  party  from  instituting  litigation  to  enforce  the  opinion  of  the
Arbitrating Accountant.

(F) The fees and expenses of the Arbitrating Accountant shall be borne by Natus or the Shareholders’ Agent depending on
which  party’s  calculation  of  Final  Net  Working  Capital  as  reflected  in  the  Unresolved  Objections  is  furthest  away  from  the
amount of Final Net Working Capital ultimately determined by the Arbitrating Accountant to be final pursuant to the provisions
of  this Section 2.02(a)(ii);  provided,  however,  that  if  the  amount  calculated  by  a  party  which  is  furthest  away  from  such  final
amount as determined by the Arbitrating Accountant is equal to or less than five percent (5%) of the final amount determined by
the Arbitrating Accountant, then Natus and the Shareholders’ Agent shall split such fees and expenses equally (and to the extent
that the Shareholders’ Agent’s calculation of such amount is furthest away from such amount, or for its one-half share of such
fees  and  expenses,  as  applicable,  Natus  and  the  Shareholders’ Agent  may  cause  the  Escrow Agent  to  deduct  such  fees  and
expenses  of  the  Arbitrating  Accountant  from  the  Escrow  Cash  and  to  pay  such  amount  to  Natus).  For  such  purpose,  the
Arbitraiting Accountant shall determine which party will be responsible for paying the fees in accordance with this paragraph. If
Natus recovers cash from Escrow Cash as provided in this paragraph, the Selling Shareholders shall replenish the Escrow Cash
being  held  by  the  Escrow Agent  with  cash  in  US$  equal  to  the  amount  of  the  fees  and  expenses,  in  the  same  way  indicated
hereinbelow.

(iii)  (A)  If  Final  Net  Working  Capital  as  shown  on  the  Final  Closing  Balance  Sheet  is  lower  than  US$  4,969,400,  and  that
deficiency exceeds the Deductible Amount (as defined in clause (B) of this Section 2.02(a)(iii)), then Natus may recover from Escrow
Cash,  within  three  Business  Days  after  the  date  on  which  the  Final  Closing  Balance  Sheet  is  finally  determined  pursuant  to  this
Section 2.02, an amount equal to the amoun in which such deficiency exceeds the Deductible Amount (such excess, the “Deficiency
Amount”).  If  the  Deficiency  Amount  is  greater  than  the  amount  of  Escrow  Cash  then  held  by  the  Escrow  Agent,  the  Selling
Shareholders  shall  pay  to  Natus,  within  seven  Business  Days  after  the  amount  of  Final  Net  Working  Capital  shall  have  been
determined, such excess amount by wire transfer in immediately available same day funds to an account designated by Natus in writing
to  the  Shareholders’ Agent.  If  Natus  recovers  cash  from  Escrow  Cash  as  provided  in  this  paragraph,  the  Selling  Shareholders  shall
replenish the Escrow Cash being held by the Escrow Agent with cash in US$ equal to the amount of the Deficiency Amount that has
been withdrawn from the Escrow Cash by Natus, and shall pay to the Escrow Agent, within seven Business Days after the amount of
Final  Net  Working  Capital  shall  have  been  determined,  such  amount  necessary  to  replenish  the  Escrow  Cash  by  wire  transfer  in
immediately available same day funds. No adjustment shall be made if the Final Net Working Capital as shown on the Final Closing

SECTION 5.02 Prohibited Activities. Each Selling Shareholder undertakes to Natus that the Prohibited Persons will not:

(a) engage in a business activity that is in competition with the Business or any material part of the Business;

(b)  solicit,  canvass,  approach  or  accept  an  approach  from  a  Person  who  was  at  any  time  during  the  twelve  months  ending  on  the

Closing a customer of the Company with a view to obtaining their customers in a business that is in competition with the Business;

(c) interfere with the relationship between the Company or the Business and its customers, employees or suppliers; and

(d) induce or help to induce an employee of the Company to leave their employment.

Notwithstanding the foregoing, and as only exemption to the non-compete obligation, the Selling Shareholders shall be entitled to engage
through  MASA  in  the  sale  of  neonatal  medical  devices  to  purchasers  in  Venezuela  who  acquire  such  devices  for  their  own  use  or  for
further  sale  or  distribution  exclusively  within  Venezuela.  This  exemption  will  only  be  valid  for  as  long  as  one  or  more  of  the  Selling
Shareholders owns a majority of the outstanding voting equity securities of MASA, all in the terms of the model of distribution agreement
attached hereto as Exhibit 2.03(VII).

SECTION 5.03 Duration of Prohibition. The undertakings in Section 5.02(a), (b), (c) and (d) shall begin on the Closing Date and end

of the third (3rd) anniversary of the Closing Date.

SECTION  5.04 Geographic Application  of  Prohibition .  The  undertakings  in  Section  5.02(a),  (b),  (c)  and  (d)  apply  if  the  activity

prohibited by Section 5.02 occurs anywhere on earth.

SECTION 5.05 Interpretation. Sections 5.02, 5.03 and 5.04 have effect together as if they consisted of separate provisions, each being
severable  from  the  other.  Each  separate  provision  results  from  combining  each  undertaking  in  Section  5.02,  with  each  period  in
Section  5.03,  and  combing  each  of  those  combinations  with  each  area  in  Section  5.04.  If  any  of  those  separate  provisions  is  invalid  or
unenforceable for any reason, the invalidity or unenforceability does not affect the validity or enforceability of any of the other separate
provisions or other combinations of the separate provisions of Sections 5.02, 5.03 and 5.04.

this Agreement shall survive the Closing Date and remain in full force and effect, regardless of any investigation or disclosure made by or
on  behalf  of  any  of  the  parties  to  this  Agreement,  until  the  one-year  anniversary  of  the  Closing  Date; provided,  however,  that  the
representations  and  warranties  contained  in  Sections  3.03,  3.04,  3.14  (with  respect  to  representations  and  warranties  in  Section  3.14
pertaining to matters of Argentinean income Taxes only), 3.15 and 3.21 shall, only with respect to Third-Party Claims, survive the Closing
Date and remain in full force and effect, regardless of any investigation or disclosure made by or on behalf of any of the parties to this

respect of any claim subject to indemnification as per Section 8.02 that is set forth in a Notice of Claim delivered prior to the applicable
expiration date of such representation or warranty shall be affected by the expiration of such representation or warranty. If the Transaction

such covenants provide that they are to be performed after the Closing Date; provided, however, that no right to indemnification pursuant to
Article VIII in respect of any claim based upon any breach of a covenant shall be affected by the expiration of such covenant.

SECTION  8.02 Agreement  to  Indemnify.  If  the  Transaction  is  consummated,  from  and  after  the  Closing,  each  of  the  Selling

incurred  and,  as  applicable,  paid  by  the  Natus  Indemnified  Persons,  calculated  net  of  actual  recoveries  under  existing  insurance  policies
(net  of  any  applicable  collection  costs  and  reserves,  deductibles,  premium  adjustments  and  retrospectively  rated  premiums)  (hereinafter
collectively referred to as “Damages”), arising out of, resulting from or in connection with: (a) any failure of any representation or warranty
of the Selling Shareholders made in this Agreement to be true and correct as of the date of this Agreement and as of the Closing Date (as
though such representation or warranty were made as of the Closing Date, except in the case of representations and warranties which by
their terms speak only as of a specific date or dates); (b) any breach of or default in connection with any of the covenants or agreements
made by the Selling Shareholders in this Agreement.

SECTION 8.03 Limitations.

(a) If the Transaction is consummated, recovery from the Escrow Cash shall be the sole and exclusive remedy under this Agreement
for the matters listed in Section 8.02 (a), except in the case of Damages resulting from Third Party Claims in connection with any failure of
any  of  the  representations  and  warranties  contained  in  Sections  3.03,  3.04,  3.14  (with  respect  to  representations  and  warranties  in
Section  3.14  pertaining  to  matters  of Argentinean  income  Taxes  only),  3.15  and  3.21  to  be  true  and  correct.  In  the  case  of  Damages
resulting from Third Party Claims in connection with any failure of any of the representations and warranties contained in Sections 3.03,
3.04, 3.14 (with respect to representations and warranties in Section 3.14 pertaining to matters of Argentinean income Taxes only), 3.15 and
3.21  to  be  true  and  correct,  or  in  the  case  of  Section  8.02  (b),  after  Natus  has  exhausted  all  amounts  of  Escrow  Cash  (after  taking  into
account all other claims for indemnification from the Escrow Cash made by Natus), the Selling Shareholders shall be liable, severally and
proportionally  to  their  pro  rata  share  as  indicated  in  Schedule  I  –  Part  B,  for  the  amount  of  any  Damages  resulting  therefrom; provided,
however, that such liability shall be limited to the aggregate amount actually paid to the Selling Shareholders pursuant to Section 2.01.

(b) If the Transaction is consummated, the Natus Indemnified Persons may not receive any Escrow Cash in respect of any claim for
indemnification under this Article VIII unless and until: (i) in case of Third-Party Claims, Damages in an aggregate amount greater than
U.S. $100,000 have been incurred and, as applicable, paid by Natus Indemnified Persons; or (ii) in case of any other claim other than a
Third-Party  Claim,  Damages  in  an  aggregate  amount  greater  than  U.S.  $500,000  have  been  incurred  and,  as  applicable,  paid  by  Natus
Indemnified  Persons.  Whenever  Damages  greater  than  the  above  mentioned  thresholds  have  been  incurred  and,  as  applicable,  paid,  the
Natus Indemnified Persons shall be entitled to receive Escrow Cash in indemnification therefore without regard to such thresholds.

SECTION 8.04 Notice of Claim.

As used herein, the term “Claim” means a claim for indemnification of Natus or any other Natus Indemnified Person for Damages
under this Article VIII. Natus may give notice of a Claim under this Agreement, whether for its own Damages or for Damages incurred by
any other Natus Indemnified Person, and Natus shall give written notice of a Claim executed by an officer of Natus (a “Notice of Claim”) to
the Shareholders’ Agent (with a copy to the Escrow Agent if the Claim involves recovery against the Escrow Cash) promptly after Natus
becomes aware of the existence of any potential claim by an Natus Indemnified Person for indemnification from Selling Shareholder under
this Article VIII, arising from or relating to:

(a) any matter specified in Section 8.02; or

(b) the assertion, whether orally or in writing, against Natus or any other Natus Indemnified Person of a claim, demand, suit, action,
arbitration,  investigation,  inquiry  or  proceeding  brought  by  a  third  party  against  Natus  or  such  other  Natus  Indemnified  Person  (in  each
such case, a “Third-Party Claim”) that is based on, arises out of or relates to any matter specified in Section 8.02.

Natus acknowledges and agrees that no direct Claim (i.e., a Claim that does not derive from a Third-Party Claim based on, arising out
or relationg to any matter specified in Section 8.02) shall be entitled to indemnification under this Agreement if such Claim is based on,
arises out or relates to Damages suffered or allegued to have been suffered by a Natus Indemnified Person derived from the adaptation or
reconciliation  of  the  Company’s  practices  and  policies  up  to  Closing  (including  without  limitation  business,  taxing,  employment,
accounting and auditing practices and policies), with different policies or practices applied by Natus after Closing, unless and to the extent
the  Company’s  practices  and  policies  up  to  Closing  violate  the  law  or  entail  a  breach  by  the  Selling  Shareholders  to  any  of  their
representations and warranties hereunder.

35

 
Except  as  provided  in  the  following  sentence,  the  period  during  which  claims  for  indemnification  under  this Article  VIII  may  be
initiated (the “Claims Period”) for indemnification from the Escrow Cash shall commence at the Closing Date and terminate at the one-year
anniversary of the Closing Date. Notwithstanding anything contained herein to the contrary, any claims for Damages for indemnification
from the Escrow Cash specified in any Notice of Claim delivered to the Shareholders’ Agent prior to expiration of the applicable Claims
Period with respect to facts and circumstances existing prior to expiration of the applicable Claims Period shall remain outstanding until
such claims for Damages have been resolved or satisfied, notwithstanding the expiration of such Claims Period. Until the expiration of the
applicable Claims Period, no delay on the part of Natus in giving the Shareholders’Agent a Notice of Claim shall relieve the Shareholders’
Agent  from  any  of  its  obligations  under  this Article VIII  unless  (and  then  only  to  the  extent  that)  Selling  Shareholders  are  materially
prejudiced thereby.

SECTION 8.05 Defense of Third-Party Claims.

(a) Natus, at its option and at any time, determine and conduct the defense or settlement of any Third-Party Claim. Natus’ counsel
with respect to any such Third-Party Claim shall be elected by the Shareholders’ Agent (in reasonable time so as not to affect the defense of
the  claim)  among  the  following  Argentine  law  firms:  (i)  Marval  O’Farrell  &  Mairal;  (ii)  Perez  Alati,  Grondona,  Benites,  Arntsen  &
Martinez  de  Hoz(H);  (iii)  Bruchou,  Fernández  Madero  &  Lombardi;  (iv)  Estudio Alegria,  Buey  Fernández,  Fissore  y  Montemerlo;  or
(v) Brons & Salas, provided that the elected law firm, prior to being confirmed as suitable to defend the Third-Party Claim, shall have to
deliver to Natus a written statement confirming that it has no conflict of interest to participate in that Third-Party Claim as counsel of Natus,
and to be elected to do so by the Selling Shareholders through the Sharheolders Agent (since that statement shall mention the names of the
Selling Shareholders, it will be kept confidential both by Natus and by the law firm).

If  Natus  is  entitled  to  indemnification  under  this Article  VIII,  the  reasonable  costs  and  expenses  reasonably  incurred  by  Natus  in
connection  with  such  defense  or  settlement  (including  reasonable  attorneys’  fees,  other  professionals’  and  experts’  fees  and  court  or
arbitration  costs  (other  than  judicial  fees  of  its  counsel,  professionals  and  experts  determined  by  the  court  on  top  of  the  reasonable  fees
agreed to be paid by Natus)) shall be included in the Damages for which Natus may seek indemnification pursuant to this Agreement.

(b)  The  Shareholders’ Agent  shall  have  the  right  to  receive  from  Natus  copies  of  all  pleadings,  notices  and  communications  with
respect to the Third-Party Claim, and shall be kept up-to-date with respect to the developments of the Third-Party Claim, to the extent that
receipt  of  such  documents  and  information  by  the  Shareholders’ Agent  does  not  affect  any  privilege  relating  to  the  Natus  Indemnified
Person.  The  Shareholders’ Agent  may  participate  in,  but  not  determine  or  conduct,  any  defense  of  the  Third-Party  Claim  or  settlement
negotiations  with  respect  to  the  Third-Party  Claim.  If  the  Shareholders’ Agent  decides  to  participate  in  the  defense,  the  Shareholders’
Agent shall employ separate counsel in any such action or claim and participate in the defense thereof, but the fees and expenses of such
counsel shall not be at the expense of Natus.

(c)  No  settlement,  acquiescence  (allanamiento),  waiver  of  defenses  or  rights  or  acknowledgement  of  debt  of  any  such  Third-Party
Claim with any third party claimant shall be made nor and shall be determinative of the existence of the Selling Shareholders’ obligation to
indemnify under this Article VIII, except the Shareholders’ Agent had consented in writing to such settlement, acquiescence (allanamiento),
waiver of defenses or rights or acknowledgement of debt, which consent shall not be unreasonably withheld, conditioned or delayed and
which shall be deemed to have been given unless the

36

 
Shareholders’  Agent  shall  have  objected  within  30  days  after  a  written  request  for  such  consent  by  Natus.  In  the  event  that  the
Shareholders’ Agent has consented to any such settlement, acquiescence ( allanamiento), waiver of defenses or rights or acknowledgement
of debt, the Selling Shareholders shall be deemed to have accepted to indemnify the Natus Indemnified Person for such Third-Party Claim,
but only to the extent of such consent.

SECTION  8.06 Contents  of  Notice  of  Claim.  Each  Notice  of  Claim  by  Natus  given  pursuant  to  Section  8.04  shall  contain  a
description, in reasonable detail (to the extent available to Natus), of the facts, circumstances or events giving rise to the Third-Party Claim,
including  the  identity  and  address  of  any  third-party  claimant  (to  the  extent  available  to  Natus)  and  copies  of  any  formal  demand  or
complaint, the amount of Damages, the basis for such anticipated liability, and the specific representation or warranty made in Article III of
this Agreement which was allegedly breached by the Selling Shareholders.

SECTION  8.07 Resolution  of  Notice  of  Claim.  Within  60  Business  Days  of  the  determination  of  the  amount  of  any  claims  for
Damages (for which Natus is entitled to receive indemnification under this Agreement), the validity and amount of which shall have been
the subject of a settlement or a final judicial determination as per Section 8.05, the Selling Shareholders, severally and propotionally to their
pro rata share as indicated in Schedule I – Part B, by so instructing in writing to the Escrow Agent, shall pay out of the Escrow Cash such
determined amount to Natus by wire transfer to the bank account designated in writing by Natus, which designation shall be provided to the
Shareholders’ Agent and the Escrow Agent not less than 10 Business Days prior to such payment.

SECTION 8.08 Release of Remaining Escrow Cash. Notwithstanding anything to the contrary in this Agreement, on the date of the
one-year anniversary of the Closing Date, the Escrow Agent shall deliver to the Selling Shareholders (proportionally to their pro-rata share
as  indicated  in Schedule  I  –  Part  B  and  C)  all  of  the  remaining  Escrow  Cash  ;  provided,  however,  that  if  any  claims  subject  to
indemnification  under  this  Article  VIII  are  unresolved,  unsatisfied  or  disputed  as  of  such  date,  then  the  Escrow  Agent  shall  retain
possession and custody of that amount of Escrow Cash that reasonably equals the amount of Damages being claimed as of such date in all
such unresolved, unsatisfied or disputed claims, and immediately upon any such claims are resolved, the Escrow Agent shall deliver to the
Shareholders’ Agent the proportional amount of Escrow Cash (if any) not required to satisfy such claims, until all Escrow Cash is entirely
released to the Selling Shareholders.

SECTION  8.09 Tax  Consequences  of  Indemnification  Payments .  All  payments  (if  any)  made  to  Natus  pursuant  to  any
indemnification obligations under this Article VIII will be treated as adjustments to the Purchase Price for tax purposes and such agreed
treatment will govern for purposes of this Agreement, unless otherwise required by law.

SECTION 8.10 Shareholders’ Agent.

(a) At the Closing, [REDACTED] shall be constituted and appointed as the Shareholders’ Agent. For purposes of this Agreement, the
term “Shareholders’ Agent” shall mean the agent for and on behalf of the Selling Shareholders to: (i) execute, as Shareholders’ Agent, this
Agreement and any agreement or instrument entered into or delivered in connection with the transactions contemplated hereby; (ii) give and
receive  notices,  instructions,  and  communications  permitted  or  required  under  this  Agreement,  the  Escrow  Agreement,  or  any  other
agreement, document or instrument entered into or executed in connection herewith, for and on behalf of any Selling Shareholder, to or

individually and not by the Shareholders’ Agent); (ii) review, negotiate and agree to and authorize Natus to reclaim cash from the Escrow
Cash in satisfaction

dispute  relating  hereto  or  to  the  transactions  contemplated  hereby  by  arbitration,  settlement  or  otherwise,  and  take  or  forego  any  or  all
actions permitted or required of any Selling Shareholder or necessary in the judgment of the Shareholders’ Agent for the accomplishment

provided herein; and (viii) take all actions necessary or appropriate in the judgment of the Shareholders’ Agent for the accomplishment of
the  foregoing,  in  each  case  without  having  to  seek  or  obtain  the  consent  of  any  Person  under  any  circumstance.  Natus  and  its  affiliates
(including without limitation, after the Closing Date, the Company) shall rely on the appointment of [REDACTED] as the Shareholders’
Agent and treat such Shareholders’ Agent as the duly appointed attorney-in-fact of each Selling Shareholder having the duties, power and
authority provided for in this Section 8.10. The Selling Shareholders shall be bound by all actions taken and documents executed by the
Shareholders’ Agent in connection with this Article VIII, and Natus shall rely on any action or decision of the Shareholders’ Agent.

authority under Section 8.10(a) shall constitute a notice or communication to or by, or a decision, action, failure to act within a designated
period  of  time,  agreement,  consent,  settlement,  resolution  or  instruction  of  all  the  Selling  Shareholders  and  shall  be  final,  binding  and

SECTION 9.02 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any
rule of law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long
as  the  economic  or  legal  substance  of  the  Transaction  is  not  affected  in  any  manner  materially  adverse  to  any  party.  Upon  such
determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good
faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in
order that the Transaction be consummated as originally contemplated to the fullest extent possible.

subject matter hereof and supersedes all prior agreements and undertakings, both written and oral, among the parties, or any of them, with
respect to the subject matter hereof, including, without limitation, the Medix I.C.S.A. Sale of Shares Summary Term Sheet entered into by
the parties. This Agreement shall not be assigned (whether pursuant to a merger, by operation of law or otherwise), except that Natus may
assign all or any of its rights and obligations hereunder to any affiliate of Natus, provided that no such assignment shall relieve Natus of its
obligations hereunder. All Annexes, Schedules (including the Disclosure Schedule) and Exhibits to this Agreement shall be considered an
integral part of the Agreement.

terms hereof, in addition to any other remedy at law or equity.

SECTION  9.06 Governing Law; Dispute Resolution.  This Agreement  shall  be  governed  by,  and  construed  in  accordance  with,  the
laws  of  the  Republic  of Argentina. Any  unresolved  disputes  between  the  parties  relating  to  the  interpretation,  performance  or  alleged
breach of this Agreement, whether before or after termination of this Agreement, shall be resolved by final and binding arbitration. If the
parties shall decide to decide to institute arbitration proceedings, it shall give written notice to that effect to the other party. The arbitration

right  it  may  have  to  a  trial  by  jury  with  respect  to  any  litigation  directly  or  indirectly  arising  out  of,  under  or  in  connection  with  this
Agreement  or  the  Transaction.  Each  of  the  parties  hereto  (a)  certifies  that  no  representative,  agent  or  attorney  of  any  other  party  has
represented, expressly or otherwise, that such other party would not, in the event of litigation, seek to enforce that foregoing waiver and
(b) acknowledges that it and the other hereto have been induced to enter into this Agreement and the Transaction, as applicable, by, among
other things, the mutual waivers and certifications in this paragraph.

SECTION 9.08 Headings. The descriptive headings contained in this Agreement are included for convenience of reference only and

SECTION  9.09 Counterparts.  This Agreement  is  executed  and  delivered  in  one  or  more  counterparts,  and  by  the  different  parties
hereto  in  separate  counterparts,  each  of  which  when  executed  shall  be  deemed  to  be  an  original  but  all  of  which  taken  together  shall
constitute one and the same agreement.

IN WITNESS WHEREOF, Natus and each of the Selling Shareholders have caused this Agreement to be executed as of the date first
