ITEM 1.  BUSINESS
 
                                    BUSINESS
 
GENERAL
 
     VitalCom provides facility-wide computer networks that acquire, interpret
and distribute real time patient monitoring information. The Company's networks
acquire physiologic data generated by proprietary ambulatory ECG monitors and
other manufacturers' bedside equipment located throughout a healthcare facility.
The Company's products are sold directly to acute care hospitals and integrated
healthcare delivery networks ("IHDNs") and on an OEM basis to patient monitoring
equipment manufacturers.
 
     The Company's facility-wide networks utilize proprietary wireless
technology and display and networking software to provide networked personal
computer-based central station surveillance of physiologic data from patients
located throughout a healthcare facility. Technicians at the central
surveillance station evaluate information acquired from ambulatory and
point-of-care monitors and, in the case of a patient emergency or other
significant event, respond by initiating immediate contact with the appropriate
caregiver through standard pager technology. Because the networks continuously
distribute real-time patient information to remote displays located throughout
the healthcare facility, the caregivers can gain immediate access to critical
patient status information. The Company believes that its networks enable
hospitals to shorten patient stays in costly intensive care units, increase
medical staff productivity, reduce costly patient transfers and improve facility
utilization.
 
     Since their introduction in 1991, the Company's facility-wide networks for
ECG data have been installed in more than 90 acute care facilities, with the
largest network providing central surveillance of up to 192 patients located in
three adjacent buildings. During the first half of 1996, the Company introduced
OpenNet, a technology designed to expand the Company's facility-wide networks by
enabling the central surveillance of additional physiologic parameters,
including blood/oxygen saturation and blood pressure, generated by third-party
patient monitoring devices. In addition to its facility-wide networks, the
Company sells central monitoring systems, clinical analysis and display software
and wireless communication components to OEM customers for use in their
departmental monitoring products.
 
INDUSTRY BACKGROUND
 
     Market-driven and governmental reform initiatives have produced significant
pressures on healthcare providers to control costs, resulting in managed care
and provider capitation arrangements that shift the economic risk of healthcare
delivery from payors to providers. In order to manage this risk, healthcare
providers are changing the way in which they operate and are increasingly
focusing on controlling the cost of delivering care.
 
     These cost control pressures are forcing hospitals to find ways to deliver
care with fewer resources and are encouraging provider consolidation and the
emergence of IHDNs. Additionally, as an increasing number of patients receive
care in lower-cost, outpatient settings, the overall acuity level of the
remaining hospital patients increases. Consequently, acute care hospitals and
IHDNs are faced with delivering quality care to more acutely ill patients using
fewer resources. In response, hospitals have increasingly turned to
technological innovation for assistance.
 
     Historically, specific technological solutions have included patient
bedside monitors and life support equipment to assist in caring for acutely ill
patients. In high-acuity departments such as intensive care units ("ICUs"),
coronary care units ("CCUs") or "step-down" units, this equipment is typically
hard-wired to a central monitoring station. This departmental approach can be
very costly to establish and maintain, and dedicating equipment to individual
departments necessitates that patients be transferred in and out of monitored
beds, creating additional transfer costs and disrupting the continuity of
patient care.
 
                                        1
<PAGE>   3
 
     Outside of these specialty departments, remote bedside equipment is used to
monitor and support patients. In this setting, a patient's physiologic
information is only available at the patient bedside, rather than where that
information can be readily available to caregivers. Additionally, caregivers in
these areas are subject to high patient/caregiver ratios, have limited time to
observe patient monitors and are often required to respond to false alarms that
result in the unproductive and costly use of the medical staff's time. The
Company believes that these existing patient monitoring solutions do not
sufficiently address the needs of hospitals to manage their increasing patient
acuity in a cost-effective manner.
 
THE VITALCOM SOLUTION
 
     The Company's facility-wide communication networks enable acute care
hospitals and IHDNs to respond to cost control pressures in the healthcare
industry by reengineering labor-intensive care delivery processes to reduce
costs. Principal benefits of the Company's solution include:
 
     - reducing patient stays in costly ICU and CCU departments through central
       surveillance of patients in less labor-intensive settings.
 
     - increasing productivity of medical staff through centralized surveillance
       of up to 48 patients by one technician, who can notify caregivers when
       patients experience a medically significant event, through standard
       paging technology.
 
     - distributing patient physiologic information to remote displays
       throughout the facility for convenient and immediate access by
       caregivers.
 
     - reducing costly patient transfers and improving overall facility
       utilization by allowing flexible bed configurations using wireless
       technology.
 
     - improving asset utilization with the Company's OpenNet application
       interfacing to third-party products through programmable interfaces. The
       Company's OpenNet application includes interfaces with monitoring devices
       from Protocol Systems, Inc., Datascope Corporation ("Datascope") and
       Johnson & Johnson Medical, Inc.
 
PRODUCTS
 
  Facility-Wide Computer Networks
 
     The Company's facility-wide computer network provides the basic
architecture for current and future product offerings. In 1991, the Company
introduced its initial facility-wide computer network for ECG data providing
acquisition, interpretation and distribution of patient ECG information. The
OpenNet application introduced in the first half of 1996 expands the Company's
network capability to multi-parameter applications by using other manufacturer's
patient monitoring and life support equipment.
 
     The Company's facility-wide computer network utilizes the following key
components: wireless communications technology; personal computer-based central
station and proprietary display software; proprietary clinical analysis
software; and a proprietary network including real-time remote display and
paging. The Company's wireless communications technology collects patient
physiologic data from the Company's proprietary ECG ambulatory transmitters and
other manufacturer's multi-parameter bedside monitoring equipment and transmits
that data in real-time to the central surveillance station for interpretation
and distribution. A central surveillance station consists of multiple, networked
personal computers and color touch-screens. The central surveillance station is
capable of simultaneously displaying up to 200 patients' physiologic data. One
trained technician is capable of monitoring up to six personal computers, each
of which receives, interprets and displays real-time physiologic patient data,
alarm settings and equipment status for up to eight patients using the Company's
proprietary software. In the event that the Company's proprietary software
detects a medically significant event, it responds with an audio or visual alarm
and prompts the technician to issue a pager call to the responsible caregiver.
The Company's proprietary software also stores up to 24 hours of real-time
physiologic patient information for subsequent review.
 
                                        2
<PAGE>   4
 
     The Company's facility-wide computer network provides for the simultaneous
distribution of real-time physiologic patient information to multiple remote
color touch-screen displays located throughout the facility by employing
proprietary real-time distribution software and industry-standard Ethernet
protocols. Remote viewing stations are located throughout the hospital, allowing
caregivers to view patient physiologic data, alarm settings and equipment status
for any patient connected to the network.
 
     ECG Applications.  The Company's facility-wide networks for ECG data
interpret and distribute patient information acquired from an ambulatory digital
telemetry transmitter, approximately the size of a television remote control,
that collects the information through sensors attached to the patient's chest.
The Company's proprietary analysis software displays patient ECG information,
including heartrate and waveform, alarm settings and equipment status for
interpretation by a trained technician. In addition, the Company's proprietary
clinical analysis software includes algorithms to analyze patient cardiac
arrhythmias, such as asystole and ventricular fibrillation. The most recent
version of the Company's analysis software received FDA approval in January
1995.
 
     Multi-Parameter OpenNet Applications.  The Company's OpenNet application
uses programmable interfaces and wireless technology to acquire, interpret and
distribute multi-parameter physiologic patient information, such as blood/oxygen
saturation, respiration, temperature, end-tidal CO2 and blood pressure from
patient monitoring and life support equipment of other vendors. The software and
wireless component of the OpenNet technology have been available since March
1996. The Company's OpenNet application includes interfaces with bedside
monitoring devices from Protocol Systems, Inc., Datascope Corporation and
Johnson & Johnson Medical, Inc. The Company intends to expand its OpenNet
technology to interface with additional patient monitoring devices in the
future, most of which will not require further FDA clearance. In addition, the
Company applied for FDA clearance in June 1996 of technology which, upon
approval, will enable the OpenNet network to connect with life support
equipment. The Company anticipates receiving FDA approval in the first half of
1997.
 
  Departmental Products
 
     The Company's departmental products are sold on a private-label basis to
equipment manufacturers and integrators, all of which manufacture patient
monitoring or medical devices and have multi-year working relationships with the
Company. Departmental products are typically used in emergency room,
post-surgical, cardiac rehabilitation and other discrete care units within a
hospital. These departmental products are custom programmed to provide
specialized analysis or display formats required by a particular patient profile
or hospital and allow equipment manufacturers and integrators to deliver a
product that satisfies the patient monitoring and reporting requirements of
their customers. The departmental product line uses many of the same components
that are used in its facility-wide networks, allowing for economies of scale in
development, manufacturing and inventory management.
 
     The departmental product line includes central workstations, proprietary
analysis software and wireless communications products, but does not include
hardware or software for real-time distribution on a facility-wide basis, nor
can it accept multiparameter information from other vendors' systems. The
Company believes that its work with departmental product resellers helps it
better understand the clinical procedures and technical protocols used to create
the OpenNet connections with its OEM customers and other vendors.
 
CUSTOMERS
 
     The Company sells its facility-wide networks to acute care hospitals and
IHDNs throughout the United States. The Company estimates that its potential
customer base includes more than 5,200 acute care hospitals in the United
States. As of December 31, 1996, the Company had direct sale installations of
its facility-wide ECG networks in more than 90 such hospitals and IHDNs,
representing more than 3,500 patient connections. In addition, the Company sells
its departmental products to leading patient monitoring device companies. In
1995, Quinton Instrument Company and Datascope accounted for approximately 14.3%
and 9.7%, respectively, of the Company's total revenues and in 1996 Quinton and
Datascope accounted for approximately 18.4% and 17.7%, respectively, of the
Company's total revenues. The loss of, or a significant reduction in sales
 
                                        3
<PAGE>   5
 
to, any such customer would have a material adverse effect on the Company's
business, operating results and financial condition.
 
SALES AND MARKETING
 
     The Company sells its facility-wide networks to acute care hospitals and
IHDNs through its direct sales force. The Company's sales force is organized by
region and targets key hospitals and IHDNs within each region. The sales cycle
for facility-wide networks has typically been nine to 18 months from initial
contact to receipt of a purchase order and generally involves multiple sales
calls on hospital purchasing, administrative and clinical personnel, product
demonstrations at select reference sites and on-site evaluations for the design
of the prospective customer's facility-wide networks. The Company markets its
facility-wide networks through direct sales calls, product demonstrations at
select reference sites, multi-day, on-site product evaluations, participation in
trade shows and advertising in trade publications.
 
     The Company sells its departmental products to leading patient monitoring
device companies, many of whom have had long-term working relationships with the
Company. The Company's departmental sales team consists of three individuals,
each of whom has significant experience in the healthcare industry. The Company
markets its departmental products to OEM customers through expansion of existing
product offerings, sales calls and participation in trade shows.
 
     The Company's focus on direct sales of facility-wide networks represents a
shift from the Company's historic dependence on indirect sales of departmental
products that were resold by OEM customers to end-user hospitals on a private
label basis. Due to fixed costs related to increased direct sales expenses, a
failure of such direct sales efforts to create an offsetting increase in
revenues and earnings would have a material adverse effect on the Company's
business, operating results and financial condition. In addition, during the
Company's long sales cycle for facility-wide networks, it may expend substantial
time, effort and funds preparing a contract proposal or negotiating a purchase
order without any guarantee that it will complete the transaction. Any
significant or ongoing failure to reach definitive agreements with direct sales
customers could have a material adverse effect on the Company's business,
operating results and financial condition. See Management's Discussion and
Analysis of Financial Condition and Results of Operations -- General.
 
CUSTOMER SUPPORT
 
     The Company provides a wide range of support services to purchasers of its
facility-wide networks. The Company's support program includes pre-installation
assistance in network design and planning; a training and maintenance program
for clinical and other hospital staff prior to installation and follow-up
on-site training after installation; 24-hour telephone technical support; and a
consignment program during the product warranty period for systems of 24
channels or more providing for the consignment of one central station, including
one spare transmitter per eight beds, at no charge. The Company provides a
one-year warranty on the equipment and software components of its facility-wide
networks. The Company will repair or replace at no charge any device or software
which it finds to be defective during the warranty period. The Company offers an
extended warranty program to its customers for an annual fee. The Company also
offers a software upgrade program with hardware upgrades, if required by the
software upgrade, for an annual fee with a four year minimum commitment.
 
TECHNOLOGY
 
     The Company believes that it has developed significant expertise in the
following core technologies: wireless communication products, real-time
application software, clinical software algorithms and networking software. The
Company benefits from the expertise of its research and development staff and
its investment in these core technologies. These core technologies allow the
Company's facility-wide networks to acquire, interpret and distribute
physiologic patient information throughout the facility in real-time. The term
"real-time" refers to the ability to deliver data with minimal latency on a
deterministic basis. "Latency" refers to the interval of time between the actual
event and the arrival of the data. "Deterministic" refers to the ability to
 
                                        4
<PAGE>   6
 
accurately predict the period of latency. Patient physiologic information is
typically shown on remote displays less than one-half second after the actual
event.
 
     Wireless Communication Products.  The Company's proprietary wireless
communication products transmit real-time physiologic information from the
patient to the central surveillance station. These communication products
operate in both VHF and UHF frequencies reserved for biomedical applications and
the 900 MHz radio band. The Company has developed over-sampling, interleaving
and digital packet algorithms providing a deterministic method for reliable
radio frequency transmissions.
 
     Real-time Application Software.  The Company has a substantial investment
in real-time application software. This includes modules for displaying
physiologic patient information such as real-time patient wave forms, the
continuous storage of patient information, trending of physiologic parameters,
event storage and reporting, a pager interface and alarm handling.
 
     Clinical Software Algorithms.  The Company has invested substantial efforts
in developing clinical analysis software to evaluate ECG information received
from the Company's transmitter and other patient monitors and report clinically
significant events. The heart beat detector uses three types of sophisticated
analysis techniques to differentiate the patient's heart beat from various
sources of noise. These include linear digital filtering, nonlinear transforms
and decision rule algorithms. These algorithms detect and classify each heart
beat for every patient on the system and detect cardiac arrhythmia events such
as asystole or ventricular fibrillation. The Company's clinical software has
received all required FDA approvals.
 
     Real-time Networking Software.  The Company has invested in developing
proprietary network algorithms that enable simultaneous viewing of real-time
physiologic patient information on multiple remote viewing stations. These
algorithms provide a deterministic method of handling network data collisions as
well as providing the minimal latency required for real-time physiologic patient
information. The Company's implementation allows for the use of industry
standard network interface controllers, hubs and routers.
 
PRODUCT DEVELOPMENT
 
     The Company's research and development strategy is to focus on expanding
the capabilities of existing products and developing new products.
 
     The Company introduced its first OpenNet applications in 1996, permitting
information from other manufacturers' multi-parameter patient monitoring to be
displayed and distributed on the Company's facility-wide computer network.
Interfaces with bedside monitoring devices from Protocol Systems, Inc.,
Datascope Corporation and Johnson & Johnson Medical, Inc. were introduced in
1996. The Company continues to expand its OpenNet applications with interfaces
to additional patient monitoring devices, many of which require no additional
FDA clearance. In addition, the Company applied for FDA clearance in June 1996
of technology which will enable the OpenNet network to connect with life support
equipment.
 
     The Company has applied for FDA clearance for a product application,
SiteLink(TM), which would enable the Company's facility-wide computer networks
to distribute real-time physiologic patient information on an interfacility
basis. The Company has under development another application that permits
caregivers access to static patient monitoring information on the Company's
facility-wide network from any remote Windows 95(TM) or NT workstation. The
Company also has under development technology that would enable the Company's
facility-wide networks to connect with HCIS products and computerized patient
records.
 
     The Company continues to evaluate emerging technologies in the
communications industry for possible use in its future facility-wide networks.
In addition, the Company continually evaluates trends in the healthcare industry
and, based on its perceptions of market requirements, may accelerate development
of certain products while deferring or canceling development of others. The
completion of the development of new or enhanced products will involve
significant expenditures without knowing whether such products will achieve the
intended benefits of cost reductions and productivity gains or whether such
products will receive market acceptance.
 
                                        5
<PAGE>   7
 
     For the years ended December 31, 1996, 1995 and 1994, total research and
development expenditures were approximately $5.4 million , $2.7 million and $1.9
million, respectively, and represented 29.6%, 11.2% and 10.8% of revenues,
respectively. The Company expects to continue to allocate significant resources
to these efforts. There can be no assurance, however, that such research and
development efforts will be successful. Any failure of the Company's OpenNet
technology or other products under development, including HCIS connectivity
products, SiteLink and the remote access monitoring information application to
achieve their intended benefits or market acceptance would have a material
adverse effect on the Company's business, operating results and financial
condition.
 
BACKLOG
 
     The Company's backlog as of December 31, 1996, 1995 and 1994 was $2.0
million, $4.1 million and $3.2 million, respectively. Backlog consists of
purchase orders for products deliverable within twelve months and primarily
represents orders for departmental products from continuing OEM customers.
Purchase orders from the Company's OEM customers are generally cancelable at any
time without penalty. The Company's backlog is not large enough to assure that
its revenue targets for a particular quarter will be met. Therefore, the Company
does not consider backlog to be a significant indication of future performance,
and sales in any quarter are dependent on orders booked and shipped during that
quarter and are not predictable with any degree of certainty.
 
MANUFACTURING
 
     The Company's manufacturing operations consist primarily of final assembly
and test and quality control of materials, components, subassemblies and
systems. The Company relies on subcontractors for printed circuit board and
component assembly. The Company obtained and maintains ISO 9001/EN 29001
certification and operates under the Good Manufacturing Practices and Medical
Device Reporting regulations of the Food and Drug Administration. Some of the
Company's products utilize components available in the short term from only a
single or limited number of sources. Certain of these components, such as some
semiconductor devices manufactured by Motorola Semiconductor Products, Inc. and
Maxim Integrated Products, Inc., have been available only on an allocation basis
in the past and could be in scarce supply again in the future. While such
allocation restrictions have not had a significant adverse effect on the Company
to date, any inability to obtain such components on a timely basis or at
commercially reasonable prices in the future could have a material adverse
effect on the Company's business, operating results and financial condition
until alternative sources could be developed or design and manufacturing changes
could be completed. The Company does not have long-term supply agreements with
its component suppliers or subcontractors. The Company's manufacturing facility
is located at its headquarters in Tustin, California.
 
INTELLECTUAL PROPERTY
 
     The Company relies on a combination of copyright, trade secret and
trademark laws, confidentiality procedures and contractual provisions to protect
its proprietary rights. The Company seeks to protect its software, circuitry
documentation and other written materials under trade secret and copyright laws,
which afford only limited protection. The Company has one patent on certain
aspects of the transmitter technology used in its products. Accucore, AccuLink,
AccuNet, OpenNet, SiteLink, Networked Monitoring and VitalCom are trademarks of
the Company. The Company cannot assure that any of its proprietary products or
technologies can be patented, that any issued patent will provide the Company
with any competitive advantages or will not be challenged by third parties, or
that the patents of others will not have an adverse effect on the Company's
ability to do business. Certain of the Company's departmental products include
900 MHz transmission technology licensed pursuant to a fully paid, five-year
agreement with a third-party. Despite the Company's efforts to protect its
proprietary rights, unauthorized parties might attempt to copy aspects of the
Company's products or to obtain and use information that the Company regards as
proprietary. Restricting unauthorized use of the Company's products is
difficult, and although the Company is unable to determine the extent to which
unauthorized copying of its software products exists, such copying could be a
potential problem. The Company believes, however, that it leads its competitors
in certain technological
 
                                        6
<PAGE>   8
 
developments, and that this lead affords it protection due in part to regulatory
requirements related to technological advances. Nevertheless, the Company cannot
assure that its protective measures for proprietary rights will be adequate or
that the Company's competitors will not independently develop similar or
superior technology, duplicate the Company's products or otherwise circumvent
its intellectual property rights.
 
COMPETITION
 
     The Company's facility-wide ECG networks compete with the departmental
systems offered by a number of competitors, including Hewlett-Packard Company,
SpaceLabs, Inc. and Marquette Medical Systems, most of which have significantly
greater financial, technical, research and development and marketing resources
than the Company. In addition, many of these competitors have long-standing
relationships with acute care hospitals and IHDNs. Furthermore, consolidation in
the healthcare industry and the emergence of IHDNs has resulted in larger
healthcare providers that consolidate their purchasing with a small number of
preferred vendors with whom they have had long-standing relationships. There can
be no assurance that the Company will be able to sell to such hospitals or IHDNs
or that the Company will be able to compete successfully with such vendors, and
any inability to do so could have a material adverse effect on the Company's
business, operating results and financial condition.
 
     The Company's OpenNet networks may face significant competition in the
future from HCIS providers, patient monitoring companies, life support device
companies and general purpose data network providers. Such potential competitors
may elect to enter this market and compete with the Company using significantly
greater financial, technical, research and development and marketing resources
than are available to the Company. In addition, the Company's success in selling
its multi-parameter OpenNet networks to hospitals and IHDNs will depend to a
large extent on its ability to interface with patient monitoring and life
support devices of other vendors. Any action on the part of such other vendors
to make such interfacing more difficult or impossible could have a material
adverse effect on the Company's business, operating results and financial
condition.
 
     The market for the Company's departmental products is also intensely
competitive. The Company competes in this market principally as an OEM supplier
to a range of patient monitoring and life support device companies, many of
which have significantly greater financial, technical, research and development
and marketing resources than the Company. There can be no assurance that current
OEM customers will not elect to design and manufacture patient monitoring and
system components currently supplied by the Company or elect to contract with
other OEM suppliers. Any such election by one or more of such companies could
have a material adverse effect on the Company's business, operating results and
financial condition.
 
     The Company believes that the principal competitive factors in its markets
are system features, product reliability, customer service and support, FDA
regulatory compliance expertise, existing relationships with hospitals and
IHDNs, company reputation, price and effectiveness of sales and marketing
efforts. In addition, the Company believes that the ability to identify the
evolving needs of the healthcare industry, and the ability to develop innovative
products to meet such needs, are important competitive factors. The Company
believes that it competes favorably with respect to these factors but there can
be no assurance that the Company will continue to compete favorably.
 
GOVERNMENT REGULATION
 
     Certain of the Company's products are regulated in the United States as
medical devices by the Food and Drug Administration under the Federal Food,
Drug, and Cosmetic Act ("FDC Act") and require pre-market clearance or approval
by the FDA prior to commercialization. In addition, certain material changes or
modifications to cleared or approved medical devices are also subject to FDA
review and clearance or approval. Pursuant to the FDC Act, the FDA regulates the
research, testing, manufacture, safety, labeling, storage, record keeping,
advertising, distribution and production of medical devices in the United
States. Non-compliance with applicable requirements can result in civil or
criminal penalties, recall or seizure of products, or total or partial
suspension of production.

     Generally, before a new device can be introduced into the market in the
United States, the manufacturer or distributor must obtain FDA clearance by
filing a 510(k) notification or obtaining approval of a premarket approval
("PMA") application. If a medical device manufacturer or distributor can
establish that a device is "substantially equivalent" to a legally marketed
device for which the FDA has not called for PMAs, the manufacturer or
distributor may seek clearance from the FDA to market the device by filing a
510(k) notification. The 510(k) notification may need to be supported by
appropriate data establishing the claim of substantial equivalence to the
satisfaction of the FDA. The FDA recently has been requiring a more rigorous
demonstration of substantial equivalence.
 
     If a manufacturer or distributor of a medical device cannot establish
substantial equivalence, the proposed device must be approved through a PMA
application supported by extensive data. The PMA application approval process
can be expensive, uncertain and lengthy. To date the Company has received
clearance on all of its products under a 510(k) process and has not been
required to file a PMA application. The FDA has published a proposed rule that
would require over forty devices, including those using arrhythmia software
produced by the Company and its competitors, following a notice period, to
receive PMA approvals or be discontinued for sale. A petition has been filed by
some industry participants, including the Company, in response to the notice, to
formally request that the FDA reclassify arrhythmia software devices from Class
III devices to Class II devices with Special Controls required. This petition is
currently under FDA review. If the FDA reclassifies arrhythmia software devices
to Class II with Special Controls, the Company's products will not require any
additional approvals. However, if the FDA does not reclassify the arrhythmia
software devices and publishes its final rule, such software devices would be
subject to the lengthy and expensive PMA process, which could interrupt or
terminate the sales of the Company's or its competitors' arrhythmia software
devices. Any such interruption or termination could have a material adverse
effect on the Company's business, financial condition and results of operations.
The Company will be required to adhere to applicable FDA regulations regarding
Good Manufacturing Practices, which include testing, control, and documentation
requirements. Failure to receive or delays in receipt of FDA clearance or
approvals, including the need for extensive clinical trials or additional data
as a prerequisite to clearance or approval, would have a material adverse effect
on the Company's business, operating results and financial condition. Changes in
existing regulations or adoption of new governmental regulations or policies
could prevent or delay required regulatory approvals of the Company's products.
 
     The Company's radio frequency transmitter devices are subject to regulation
by the FCC, and applicable approvals must be obtained before shipment of such
products. Any delay or failure to obtain required FCC approvals in the future,
if any, could cause the delay or loss of sales of the Company's products and
therefor have a material adverse effect on the Company's business, financial
condition and result of operations.
 
     The Company believes that all of its products designated for sale in the
United States meet applicable Federal Communications Commission regulations,
including US FCC Part 15 for electromagnetic emissions. The FCC approval process
starts with the collection of test data that demonstrates that a product meets
the requirements stated in Part 15 of the FCC regulations. This data is then
included as part of a report and application that is submitted to the FCC
requesting approval. The FCC may grant or withhold approval or request
additional information. Any failure of the Company's products to conform to
governmental regulations could delay the introduction of new products and
otherwise adversely affect the Company.
 
     If the Company were to attempt to market its products and components in
Europe and certain other foreign jurisdictions, the Company and its distributors
and agents would have to obtain required regulatory approvals and clearances and
otherwise comply with extensive regulations regarding safety and manufacturing
processes and quality. These regulations, including the requirements for
approvals or clearance to market, and the time required for regulatory review
vary from country to country.

GENERAL
 
     The Company provides facility-wide computer networks that acquire,
interpret and distribute real time patient monitoring information. The Company's
networks acquire physiologic data generated by proprietary ambulatory ECG
monitors and other manufacturers' bedside equipment located throughout a
healthcare facility. The Company's products are sold directly to acute care
hospitals and integrated healthcare delivery networks ("IHDNs") and on an OEM
basis to patient monitoring equipment manufacturers.
 
     During the year ended December 31, 1996 direct sales of the Company's
facility-wide computer networks of $8,163,959 were 37.9% lower than the
$13,139,844 achieved in the year ending December 31, 1995. The Company believes
that the reduction in sales resulted from a mid-1996 restructuring of the sales
force and implementation of a new selling method focused on quantifying the
financial benefits and re-engineering opportunities enabled by its facility-wide
network. These changes shifted the Company's sales strategy from a clinical to a
financial and information systems focus. This new strategy lengthened the sales
cycle and disrupted focus on the Company's selling its core competency in
clinical applications. Although the Company believes that sales force
productivity will increase in 1997, there can be no assurance that the Company's
sales efforts will result in increased sales levels in future periods.
 
     In November 1996 the Company restructured operations, which included both
expense and employee reductions, to bring expenses more closely in line with
revenues. As a result, the Company incurred a restructuring charge of $480,996
and a $415,000 charge to operating expenses for employee severance, termination
costs, and other restructuring accruals.
 
     Revenues from sales of facility-wide networks are recognized upon shipment.
The sales cycle for facility-wide networks has typically been from nine to 18
months. The Company has experienced seasonal variations in sales of its
facility-wide networks, with sales in the first quarter typically lower than the
preceding fourth quarter's sales due to customer budget cycles and sales
remaining relatively flat during the third quarter. Furthermore, a large
percentage of a particular quarter's shipments of facility-wide networks has
historically been booked in the last weeks of the quarter.
 
     Revenues from sales of departmental products are recognized upon shipment.
The selling cycle for departmental products varies depending upon product mix
and the extent to which the Company develops customized operating software for a
particular OEM customer. In addition, the Company has experienced seasonal
variations in sales of its departmental products, with third quarter sales of
departmental products generally being lower than other quarters.
 
                                       11
<PAGE>   13
 
     The Company's products are generally shipped as orders are received and,
accordingly, the Company typically operates with limited backlog. As a result,
sales in any quarter are dependent on orders booked and shipped in that quarter.
 
     To date the Company has not capitalized software development expenses.
However, the development of new products or the enhancement of existing products
may require capitalization of such expenses in the future. See Note 1 to the
Financial Statements.

COMPARISON OF THE YEARS ENDED 1996, 1995 AND 1994
 
     Total Revenues.  Total revenues consist of revenue from sales of
facility-wide networks and departmental products, together with fees for
installation and servicing of products. Total revenues decreased 23.3% to $18.4
million in 1996 from $24.0 million in 1995. Total revenues increased 40.2% to
$23.9 million in 1995 from $17.1 million in 1994. Revenues from facility-wide
computer network sales decreased 37.9% to $8.2 million from $13.1 million in
1995. Revenues from facility-wide network sales increased 55.2%, or $4.7
million, to $13.1 million in 1995 from $8.5 million in 1994. Revenues from
departmental product sales decreased 5.7% to $10.2 million from $10.8 million in
1995. Revenues from departmental product sales increased 25.5%, or $2.2 million,
to $10.8 million in 1995 from $8.6 million in 1994. The absolute increase in
facility-wide network sales in 1995 and was due to expansion of the Company's
sales and marketing efforts, greater market penetration and increasing customer
acceptance of the Company's products. The decrease in facility-wide network
sales in 1996 was due to a shift to a new selling method focused on selling the
financial benefits and re-engineering opportunities enabled by the Company's
products, changes made to the sales force to address these shifts and the
attendant disruption in sales to prospects with a clinical ECG focus. During
1995 departmental product sales increased as the Company's largest customer
experienced growth from an updated product release and a new customer increased
market penetration for their product. In 1996 departmental product sales
decreased slightly with the expected reduction of sales from an existing
customer which was not offset by increased revenues from new customers.
 
                                       12

     Gross Margins.  Cost of goods sold generally includes material, direct
labor, overhead and, for facility-wide networks, installation expenses. Cost of
sales decreased 6.0% to $9.7 million from $10.3 million in 1995, on a 23.3%
decrease in revenues in 1996. Cost of sales increased 29.5%, or $2.3 million, to
$10.3 million in 1995 from $8.0 million in 1994, on a 40.2% revenue increase in
1995. Gross margins were 47.3%, 57.0% and 53.5% in 1996, 1995 and 1994,
respectively. The increase in gross margin in 1995 as compared to 1994 was
attributable to product mix and a greater percentage of software content which
carries higher gross margins. The decrease in gross margin in 1996 as compared
to 1995 was due to lower revenues in 1996 with fixed costs in overhead a higher
percentage of revenues.
 
     Sales and Marketing Expenses.  Sales and marketing expenses include
payroll, commissions and related costs attributable to direct and OEM sales and
marketing personnel, travel and entertainment expenses, and other promotional
expenses. Sales and marketing expenses increased 47.7% or $3.1 million, to $9.5
million in 1996 from $6.4 million in 1995. Sales and marketing expenses
increased 76.8%, or $2.8 million, to $6.4 million in 1995 from $3.6 million in
1994. The increase in sales and marketing expenses in 1996 and 1995 was
primarily attributable to an increase in direct sales payroll and related
support, training, recruitment and travel and entertainment expenses associated
with an increased number of sales professionals. The Company spent $850,000 in
1996 to voluntarily upgrade selected facility-wide network customers to provide
a direct upgrade path for future expansion purchases.
 
     Research and Development Expenses.  Research and development expenses
include payroll and related costs attributable to research and development
personnel, prototyping expenses and other costs. Research and development
expenses increased 103.3% or $2.8 million, to $5.4 million in 1996 from $2.7
million in 1995. Research and development expenses increased 44.3%, or $820,000,
to $2.7 million in 1995 from $1.9 million in 1994. The absolute increase in
research and development expenses in 1996 and 1995 was due primarily to an
increase in the number of research and development personnel, increased
recruitment fees and an increasing number of projects.
 
     General and Administrative Expenses.  General and administrative expense
includes accounting, finance, MIS, human resources, general administration,
executive officers and professional fee expenses. General and administrative
expenses increased 52.5%, or $863,000, to $2.5 million in 1996 from $1.6 million
in 1995. General and administrative expenses increased 53.4%, or $572,000, to
$1.6 million in 1995 from $1.1 million in 1994. The increase in absolute
spending in 1996 and 1995 is attributable to the addition of an executive
officer in the third quarter of 1995, other headcount increases, related
recruiting and relocation expenses and during 1996, the legal, compliance and
investor relations expenses associated with being a public company.
 
     Restructuring Charge.  Restructuring charges resulted from the Company's
November 1996 restructuring of operations and an executive reorganization and
include severance and other employee termination costs. Included in accrued
liabilities at December 31, 1996 is approximately $325,000 which will be paid by
the end of the fourth quarter of 1997.
 
     Other Income (Expense), Net.  Other income (expense), net consists
primarily of interest income earned on proceeds from the Company's initial
public offering, net of payments made in respect of outstanding indebtedness.
Other income (expense), net in 1996 increased to $975,000 in income as compared
to expense of $130,000 in 1995. Other income (expense), net in 1995 decreased to
$130,000 from $174,000 in 1994. Other income, net in 1996 was derived from
interest earned on the proceeds from the Company's February 1996 initial public
offering, while interest payments on the Company's long term debt were
eliminated as the loan was paid off in February 1996. Interest (expense) in 1995
declined due to the absence of the amortization of loan fees and lower interest
payments due to reduced debt levels.
 
     Provision (Benefit) for Income Taxes.  The Company's 1996 effective tax
benefit was 23.0% as the Company only recognized a benefit for the amount of
refundable federal taxes of $2.7 million as a result of the carryback of its net
operating loss, offset by the establishment of a valuation allowance of $748,000
against previously deferred tax assets, for a net tax benefit of $1.9 million.
The Company's effective tax rate was 43.0% and 40.5% in 1995 and 1994,
respectively.

LIQUIDITY AND CAPITAL RESOURCES
 
     The Company has historically financed its operations (including capital
expenditures) through cash flow from operations, cash and cash equivalent
balances, a bank line of credit and long-term debt. During 1995, the Company
raised net proceeds of approximately $2.8 million from the issuance of Common
and Preferred Stock. During the year ended December 31, 1996 the Company issued
2,300,000 shares of common stock in its February 1996 initial public offering,
raising $25.6 million, net of expenses.
 
     In 1996, the Company generated approximately $23.0 million of cash from
financing and investing activities which consisted of $25.6 million, net, from
the sale of 2,300,000 shares of common stock in the Company's February 1996
initial public offering, approximately $153,000 from the issuance of 32,815
shares of the Company's common stock under its Employee Stock Purchase Plan and
approximately $28,000 from the issuance of 34,250 shares of the Company's common
stock for exercises of stock options under the Company's 1993 Stock Option Plan.
The Company used approximately $1.4 million of cash for purchases of property
and approximately $1.6 million for the repayment of long term debt in financing
and investing activities. The Company used cash from operating activities of
$5.0 million to fund a $6.4 million net loss, an increase in inventories and
income tax receivable and generated cash through a decrease in accounts
receivable and an increase in accrued liabilities and accrued warranty costs.
 
     In 1995, the Company generated approximately $1.7 million of cash from
financing activities which consisted of net proceeds from common stock and
preferred stock issuances of approximately $2.8 million offset in part by
dividends on preferred stock then outstanding, repayment of long-term debt and
the repurchase of common stock. The Company used cash from operating activities
to fund increases in accounts receivable and inventories and generated cash by
increasing accrued liabilities. The Company used approximately $752,000 of cash
in investing activities primarily for property purchases.
 
     In 1994 the Company generated cash from operating activities of
approximately $2.0 million which consisted primarily of net income and
depreciation and amortization, offset by increases in accounts receivable,
deferred taxes and inventories. Cash used in investing activities in 1994 of
$410,000 was primarily expended on property purchases. Net cash of approximately
$976,000 was used by financing activities in 1994 primarily for dividend
payments on preferred stock of $615,000 and long-term debt repayments.
 
     At December 31, 1995, the Company had a secured promissory note in the
amount of $1,541,667 due to Silicon Valley Bank which bore interest at the
bank's prime rate plus 3.0% (11.75% at December 31, 1995) per annum, payable
monthly in arrears. In February 1996 the Company paid the loan off in full,
without pre-payment penalty. In August 1996, the Company entered into a secured
lending arrangement (the "Agreement") with Silicon Valley Bank, providing for a
$5.0 million revolving line of credit bearing interest at the bank's prime rate.
The bank does not have security interest in any of the Company's assets unless
the Company is borrowing under the line of credit and fails to comply with
certain financial covenants. The Agreement expires in August 1997 and has
certain financial and other covenants. At December 31, 1996, there were no
borrowings outstanding under the Agreement and the Company was in compliance
with all covenants. As such the bank held no security interest in any of the
Company's assets.
 
     The Company's principal commitment at December 31, 1996 consisted of a
lease on its office and manufacturing facility. The Company expects to spend
approximately $1.5 million for capital expenditures during 1997.
 
     The Company believes that existing cash resources, cash flows from
operations, if any, and line of credit facilities will be sufficient to fund the
Company's operations for at least the next twelve months.
 
FACTORS THAT MAY AFFECT FUTURE OPERATING RESULTS
 
     Dependence on Increased Market Acceptance of Facility-Wide Computer
Networks.  In 1996, sales of the Company's facility-wide networks decreased
37.9% to $8.2 million from $13.1 million in 1995. If the Company is not
successful in marketing and selling its facility-wide Networked Monitoring
solutions, or if commercial introduction of new applications and enhancements is
delayed, the Company's business, operating results and financial condition would
be materially adversely affected. In addition, although the Company's
 
                                       14
<PAGE>   16
 
Networked Monitoring products have been installed in over 95 hospitals, there is
no assurance that the Company's products will achieve the hospital penetration
which the Company anticipates.
 
     Fluctuations in Quarterly Results.  The Company's quarterly operating
results have fluctuated in the past and may fluctuate significantly from quarter
to quarter in the future as a result of a number of factors, including, but not
limited to the size and timing of orders; the length of the sales cycle; the
Company's success in expanding its sales and marketing programs and the effects
of changes in sales force alignment; the ability of the Company's customers to
obtain budget allocations for the purchase of the Company's products; changes in
pricing policies or price reductions by the Company or its competitors; mix of
sales between facility-wide networks and departmental products; the timing of
new product announcements and introductions by the Company or its competitors;
deferrals of customer orders in anticipation of new products or product
enhancements; the Company's ability to develop, introduce and market new
products and product enhancements; market acceptance of new products or product
enhancements; the Company's ability to control costs; the availability of
components; regulatory compliance and timing of regulatory approvals; and
general economic factors.
 
     The Company's products are generally shipped as orders are received and,
accordingly, the Company has historically operated with limited backlog. As a
result, sales in any quarter are dependent on orders booked and shipped in that
quarter and are not predictable with any degree of certainty. Further, a large
percentage of any quarter's shipments have historically been booked in the last
weeks of the quarter. In addition, a significant portion of the Company's
expenses are relatively fixed, and the amount and timing of increases in such
expenses are based in large part on the Company's expectations for future
revenues. If revenues are below expectations in any given quarter, the adverse
effect may be magnified by the Company's inability to maintain gross margins and
to decrease spending to compensate for the revenue shortfall. Further, the
Company has sometimes experienced seasonal variations in operating results, with
sales in the first quarter being lower than in the preceding fourth quarter's
sales due to customer budget cycles and sales remaining relatively flat during
the third quarter.
 
     Lengthy Sales Cycle; Increasing Size of Orders.  The decision by a
healthcare provider to replace or substantially upgrade its clinical information
systems typically involves a major commitment of capital and an extended review
and approval process, and this review and approval process is becoming more
complex, more financially oriented and increasingly subject to overall
integration into the hospital's information systems planning. The sales cycle
for the Company's facility-wide networks has typically been nine to 18 months
from initial contact to receipt of a purchase order. During this period,
VitalCom may expend substantial time, effort and funds preparing a contract
proposal and negotiating a purchase order without any guarantee that the Company
will complete the transaction. Any significant or ongoing failure to reach
definitive agreements with customers could have a material adverse effect on the
Company's business, operating results and financial condition.
 
     Competition.  The Company's facility-wide networks for ECG data compete
with the departmental systems offered by a number of competitors, including
Hewlett-Packard Company, SpaceLabs, Inc. and Marquette Electronics, Inc., most
of which have significantly greater financial, technical, research and
development and marketing resources than the Company. In addition, many of these
competitors have longstanding relationships with acute care hospitals and IHDNs.
There can be no assurance that the Company will be able to sell to such
hospitals or IHDNs or that the Company will be able to compete successfully with
such vendors, and any inability to do so could have a material adverse effect on
the Company's business, operating results and financial condition. While the
Company is not aware of any competitive multi-parameter facility-wide networks
currently available, the Company's OpenNet networks may face significant
competition in the future from HCIS providers, patient monitoring companies,
life support device companies and general purpose data network providers. Such
potential competitors may elect to enter this market and compete with the
Company using significantly greater financial, technical, research and
development and marketing resources than are available to the Company. In
addition, the Company's success in selling its multi-parameter OpenNet networks
to hospitals and IHDNs will depend to a large extent on its ability to interface
with patient monitoring and life support devices of other vendors. Any action on
the part of such other vendors to make such interfacing more difficult or
impossible could have a material adverse effect on the Company's business,
 
                                       15
<PAGE>   17
 
operating results and financial condition. The market for the Company's
departmental products is also intensely competitive. The Company competes in
this market principally as an OEM supplier to a range of patient monitoring and
life support device companies, many of which have significantly greater
financial, technical, research and development and marketing resources than the
Company. There can be no assurance that current OEM customers will not elect to
design and manufacture patient monitoring and system components currently
supplied by the Company or elect to contract with other OEM suppliers. Any such
election by one or more of such companies could have a material adverse effect
on the Company's business, operating results and financial condition.
 
     Customer Concentration; Dependence on Departmental Products.  The Company's
departmental product sales, which represented approximately 45.2% and 55.6% of
the Company's total net revenues in 1995 and 1996, respectively, have
historically been to a small number of OEM customers. In 1995, Quinton
Instrument Company ("Quinton") and Datascope Corporation ("Datascope") accounted
for approximately 14.3% and 9.7%, respectively, of the Company's total revenues
and in 1996 Quinton and Datascope accounted for approximately 18.4% and 17.7%,
respectively, of the Company's total revenues. The loss of, or a reduction in
sales to, any such OEM customer would have a material adverse effect on the
Company's business, operating results and financial condition.
 
     Technological Change; Need to Develop New Products.  Many aspects of the
medical equipment industry are undergoing rapid technological change, changing
customer needs, frequent new product introductions and evolving industry
standards. Historically, the Company derived substantially all of its revenue
from sales of its facility-wide networks for ECG data and departmental products.
The Company believes that as the market for these products matures, VitalCom's
future success will depend upon its ability to develop and introduce on a timely
basis new products and product enhancements that keep pace with technological
developments and that address the increasingly sophisticated needs of acute care
hospitals and IHDNs. In addition, the introduction of competing products
embodying new technologies and the emergence of new industry standards could
render the Company's existing products unmarketable or obsolete. If the Company
is unable to develop and introduce product enhancements and new products in a
timely and cost-effective manner in response to changing market conditions or
customer requirements, the Company's business, operating results and financial
condition will be materially adversely affected.
 
     Uncertainty and Consolidation in Healthcare Industry.  The healthcare
industry is subject to changing political, economic and regulatory influences
that may affect the procurement practices and operation of healthcare providers.
Many healthcare providers are consolidating to create larger hospitals and
IHDNs. This consolidation reduces the number of potential customers for the
Company's products, and the increased bargaining power of these organizations
could lead to reductions in the amounts paid for the Company's products. These
larger hospitals and IHDNs may concentrate their purchases on a small number of
preferred vendors with whom they have had longstanding relationships. There can
be no assurance that the Company will be able to sell to such hospitals or IHDNs
or that the Company will be able to compete successfully with such vendors. The
impact of these developments in the healthcare industry is difficult to predict
and could have a material adverse effect on the Company's business, operating
results and financial condition.
 
     Limited Intellectual Property Protection.  The Company relies on a
combination of copyright, trade secret and trademark laws, confidentiality
procedures and contractual provisions to protect its intellectual property. The
Company seeks to protect its software, circuitry documentation and other written
materials under trade secret and copyright laws, which afford only limited
protection. The Company cannot assure that its protective measures for
proprietary rights will be adequate or that the Company's competitors will not
independently develop similar or superior technology, duplicate the Company's
products or otherwise circumvent its intellectual property rights. Although the
Company has never received a claim that its products infringe a third party's
intellectual property rights, there can be no assurance that third parties will
not in the future claim infringement by the Company with respect to current or
future products or proprietary rights. Any such claims, regardless of their
merit, could be time consuming, result in costly litigation, delay or prevent
product shipments or require the Company to enter into costly royalty or
licensing agreements. The impact of any of these developments could have a
material adverse effect on the Company's business, operating results and
financial condition.
 
                                       16
<PAGE>   18
 
     Risk of Product Liability Claims.  Certain of the Company's products
provide applications that relate to patient physiologic status or other
clinically critical information. Any failure by the Company's products to
provide accurate and timely information could result in product liability and
warranty claims against the Company by its customers or their patients. The
Company maintains insurance against claims associated with the use of its
products, but there can be no assurance that its insurance coverage would
adequately cover any claim asserted against the Company. A successful claim
brought against the Company in excess of its insurance coverage or outside the
scope of the Company's insurance coverage could have a material adverse effect
on the Company's business, operating results and financial condition. Even
unsuccessful claims could result in the expenditure of funds in litigation and
diversion of management time and resources.
 
     Dependence on Sole Source Components.  Certain of the Company's products
utilize components that are available in the short term only from a single or a
limited number of sources, have been available only on an allocation basis in
the past and could be in scarce supply again in the future. Any inability to
obtain components in the amounts needed on a timely basis or at commercially
reasonable prices could result in delays in product introductions, interruption
in product shipments or increases in product costs, which could have a material
adverse effect on the Company's business, operating results and financial
condition until alternative sources could be developed or design and
manufacturing changes could be completed.
 
     Dependence on and Need to Recruit Key Personnel.  The Company's success
depends to a large extent on its ability to attract and retain key personnel.
Mr. Judson, President and Chief Executive Officer and Chairman of the Board has
experienced back related pain which has periodically prevented him from working
full time. In addition, Mr. Judson had a heart attack in 1989, took a one-week
leave in December 1995 for a balloon angioplasty procedure and returned to work
in January 1996. The loss of the services, either temporarily or permanently, of
any of the members of senior management or other key employees, particularly in
sales and marketing and research and development, could have a material adverse
effect on the Company's business, operating results and financial condition. In
addition, the Company's future success depends to a large extent on its ability
to attract and retain additional key management, sales and marketing and
research and development personnel. Competition for such personnel is intense.
There can be no assurance that the Company will be successful in attracting and
retaining such personnel, and the failure to do so could have a material adverse
effect on the Company's business, operating results and financial condition.
 
     Management of Growth.  The Company's ability to manage future growth, if
any, could place a significant strain on the Company' personnel and resources
and will depend on its ability to continue to implement and improve operational,
financial and management information and controls systems on a timely basis. Any
failure to do so could have a material adverse effect on the Company's business,
operating results and financial condition.
 
     Government Regulation.  The manufacture and sale of medical devices,
including the Company's products, is subject to extensive regulation by numerous
governmental authorities. In the United States, the Company's products are
regulated as medical devices and are subject to the Food and Drug
Administration's pre-clearance or approval requirements. The Company has
received clearance from the FDA to market its current products through the
510(k) premarket notification process. There can be no assurance that a similar
510(k) clearance for any future product or enhancement of an existing product
will be granted or that the process will not be lengthy. If the Company cannot
establish that a product is "substantially equivalent" to certain legally
marketed devices, or if FDA regulatory changes currently under consideration
with respect to arrhythmia software are adopted, the 510(k) clearance procedure
will be unavailable and Company will be required to utilize the longer and more
expensive premarket approval ("PMA") process. Failure to receive or delays in
receipt of FDA clearances or approvals, including the need for extensive
clinical trials or additional data as a prerequisite to clearance or approval,
could have a material adverse effect on the Company's business, operating
results and financial condition. Sales of medical devices and components outside
of the United States are subject to international regulatory requirements that
vary from country to country. There can be no assurance that the Company will be
able to obtain further clearance or approvals for its products or components on
a timely basis or at all, and delays in receipt of, loss of or failure to
receive such approvals or clearances could have a material adverse effect on the
Company's business, operating results and financial condition.

years in the period ended December 31, 1996. Our audits also included the
financial statement schedule listed in Item 8. These financial statements and
financial statement schedule are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements and
financial statement schedule based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. 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 financial statements present fairly, in all material
respects, the financial position of the Company at December 31, 1995 and 1996
and the results of its operations and its cash flows for each of the three years
in the period ended December 31, 1996 in conformity with generally accepted
accounting principles. Also, in our opinion, such financial statement schedule,
when considered in relation to the financial statements taken as a whole,
presents fairly, in all material respects, the information set forth therein.

                         NOTES TO FINANCIAL STATEMENTS
 
1.  GENERAL AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     General and Nature of Operations -- The Company provides communication
networks that acquire, interpret and distribute real-time physiologic data
generated by point-of-care patient monitors located throughout a healthcare
facility. The Company sells facility-wide networks to acute care hospitals and
integrated health delivery networks ("IHDNs") in the United States. In addition,
the Company sells certain components, monitoring systems, clinical analysis and
display software and wireless communications components to OEM customers for use
in their departmental monitoring products.
 
     During the 1994 year, New PCI, Inc. changed its name to ACCUCORE, Inc. and
in January 1996, changed its name to VitalCom Inc. (the "Company").
 
     Consolidation -- In December 1995, the Company and its wholly owned
subsidiary merged. The merger has been treated as a reorganization of entities
under common control and accounted for in a manner similar to that of a pooling
of interests. The Company's financial statements have been restated accordingly.
 
     Cash Equivalents -- Cash equivalents generally represent highly liquid
investments purchased with an original maturity date of three months or less.
 
     Inventories -- Inventories are stated at the lower of weighted average cost
or market.
 
     Property -- Property is stated at cost. Depreciation is provided using the
straight-line method and the double declining balance method over the estimated
useful lives of the related assets, generally three to eight years. Leasehold
improvements are amortized over the lesser of the estimated useful lives of the
related improvements or the related lease term.
 
     Goodwill -- Goodwill represents the excess purchase cost over the net
assets acquired and is amortized over 20 years using the straight-line method.
The Company periodically evaluates the recoverability of goodwill based on a
profitability analysis related to its product sales and has determined that
there was no impairment of goodwill at December 31, 1996.
 
     Intangible Assets -- Intangible assets represent the value of the Company's
developed technology as determined by an independent appraisal and has been
amortized over the estimated recovery period of three years on a straight-line
basis.
 
     Long Lived Assets -- The Company accounts for the impairment and
disposition of long-lived assets in accordance with SFAS No. 121, Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of.
In accordance with SFAS No. 121, long-lived assets to be held are reviewed for
events or changes in circumstances which indicate that their carrying value may
not be recoverable. The Company will periodically review the carrying value of
long-lived assets to determine whether or not an impairment to such value has
occurred.
 
     Revenue Recognition -- Revenues from both facility-wide networks and
departmental products, which consist of both hardware and software, are
recognized upon shipment if no significant vendor obligations remain and
collection of the related receivable is probable. The Company accounts for
insignificant vendor obligations and post-contract support at the time of
product delivery by accruing such costs and recognizing them ratably on
completion of performance. There is no right of return on sales. Revenues
related to service contracts with customers, which are insignificant, are
deferred and amortized over the terms of the contracts, generally one year.
 
     Software Development Costs -- Development costs incurred in the research
and development of new software products and enhancements to existing software
products are expensed as incurred until technological feasibility has been
established. After technological feasibility is established, any additional
costs would be capitalized in accordance with Statement of Financial Accounting
Standards No. 86, Accounting for the Costs of Computer Software to be Sold,
Leased or Otherwise Marketed. Because the Company believes that its
 
                                       23

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
current process for developing software is essentially completed concurrently
with the establishment of technological feasibility, no costs are capitalized as
of December 31, 1994, 1995 or 1996.
 
     Income Taxes -- The Company accounts for income taxes in accordance with
Statement of Financial Accounting Standard No. 109 (SFAS No. 109), Accounting
for Income Taxes. This statement requires the recognition of deferred tax assets
and liabilities for the future consequences of events that have been recognized
in the Company's financial statements or tax returns. Measurement of the
deferred items is based on enacted tax laws.
 
     Pro Forma Net Income Per Share -- Pro forma net income per share is
computed by dividing net income by the weighted average number of common and
common equivalent shares outstanding. Weighted average common and common
equivalent shares include common shares, stock options using the treasury stock
method and the assumed conversion of all outstanding shares of preferred stock
into shares of common stock.
 
     Pursuant to Securities and Exchange Commission Staff Accounting Bulletin
Topic 4D, stock options granted during the twelve months prior to the date of
the initial filing of the Company's Form SB-2 Registration Statement have been
included in the calculation of common equivalent shares using the treasury stock
method.
 
     Net Income to Common Stockholders -- Net income to common stockholders
represents net income less preferred dividends and accretion attributable to
preferred stock redemption value (See Note 6).
 
     Stock Split -- In connection with the June 1, 1995 transactions discussed
in Note 6, common stockholders received an additional 409,197 shares of common
stock due to a 1.612 for 1 common stock split. Pro forma per share amounts
reflect such stock split.
 
     New Accounting Pronouncement -- In October 1995, the Financial Accounting
Standards Board issued Statement of Financial Accounting Standards No. 123,
"Accounting for Stock Based Compensation." The Company has determined that it
will not change to the fair value method and will continue to use Accounting
Principle Board Opinion No. 25 for measurement and recognition of employee stock
based transactions. (See Note 8).
 
     Use of Estimates -- The preparation of financial statements in conformity
with generally accepted accounting principles necessarily requires management to
make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from these estimates.
 
     Reclassifications -- Certain reclassifications have been made to the 1994
and 1995 financial statements to conform to the 1996 presentation.
 
  Significant Concentrations.
 
     Customer Concentrations -- The Company's departmental product sales, which
represented 45.2% and 55.6% of the Company's total revenues in 1995 and 1996
respectively, have historically been concentrated in a small number of OEM
customers. Approximately 34.0%, 30.4% and 41.7% of 1994, 1995 and 1996 sales,
respectively, were to three customers. The loss of, or a reduction in sales to,
any such OEM customers would have a material adverse effect on the Company's
business, operating results and financial condition. Further, sales of the
Company's departmental products are dependent to a large extent upon the
Company's OEM customers selling patient monitoring devices that include the
Company's departmental products as necessary components. Any inability of such
OEM customers to sell such systems, or any election by such OEM customers not to
include the Company's products as components therein, could have a material
adverse effect on the Company's business, operating results and financial
condition.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     Supplier Concentration -- Certain of the Company's products utilize
components that are available in the short term only from a single or a limited
number of sources. Certain of these components, such as semiconductor devices,
have been available only on an allocation basis in the past and could be in
scarce supply again in the future. Any inability to obtain components in the
amounts needed on a timely basis or at commercially reasonable prices could
result in delays in product introductions or interruption in product shipments
or increases in product costs, which could have a material adverse effect on the
Company's business, operating results and financial condition until alternative
sources could be developed or design and manufacturing changes could be
completed. Any such design or manufacturing changes or increased costs could
result in significant expenses in a particular quarter and therefore could
materially adversely affect operating results for any such quarter or other
period.

3.  REVOLVING LINE OF CREDIT
 
     In August 1996, the Company entered into a secured lending arrangement (the
"Agreement") with Silicon Valley Bank, providing for a $5.0 million revolving
line of credit bearing interest at the bank's prime rate. The bank does not have
security interest in any of the Company's assets unless the Company is borrowing
under the line of credit and fails to comply with certain financial covenants.
The Agreement expires in August 1997 and has certain financial and other
covenants. At December 31, 1996, there were no borrowings outstanding under the
Agreement and the Company was in compliance with all covenants. As such the bank
held no security interest in any of the Company's assets.
 
4.  LONG-TERM DEBT
 
     At December 31, 1995, the Company had a secured promissory note in the
amount of $1,541,667 due to Silicon Valley Bank which bore interest at the
bank's prime rate plus 3.0% (11.75% at December 31, 1995) per annum, payable
monthly, in arrears. In February 1996 the Company paid the loan off in full,
without pre-payment penalty.
 
5.  CAPITAL AND OPERATING LEASES
 
     The Company leases its facilities and certain equipment under a
noncancelable operating lease and a capital lease that expires at various dates
through 2001.

     The Company's rent expense was $104,836, $109,113 and $340,127 for the
years ended December 31, 1994, 1995 and 1996, respectively.
 
6.  STOCKHOLDERS' EQUITY
 
     In 1994 the Company had two classes of common stock: Series A common stock,
which entitled the holder to one vote for each share and Series B common stock,
which was non-voting stock, except under certain circumstances, and which was
convertible into Series A common stock under certain circumstances. In the 1995
transaction described below, all of the Series A and B common stock was either
repurchased, sold or exchanged for newly issued common or preferred stock.
 
     The Company had two classes of preferred stock designated Series A and
Series B. The Series A and B preferred shares issued and outstanding at December
31, 1994 were 6,425,000 and 1,193,392, respectively. There were no Series A and
B preferred shares issued and outstanding at December 31, 1995. The shares had a
liquidation-preference of $1.00 per share at December 31, 1994. The shares were
scheduled for redemption in equal installments on December 11, 1998 and December
11, 1999. The Series A and B preferred shares bore dividends of 8% per share,
payable on December 31, 1993 and quarterly thereafter commencing March 31, 1994,
as amended by the First Amendment to the Subordination and Intercreditor
Agreement (the "Agreement"). The Agreement provided that Series A preferred
dividends were due on the Modified Payment Date which was the sooner of 30 days
after the scheduled dividend date or five business days after the delivery of
pro forma financial statements by the Company to the Bank and a stockholder
showing that the Company remained within all financial covenants specified by
the loan agreement with the Bank after the payment of dividends. Series A
preferred stock had certain additional rights and preferences, including a
dividend rate of 9% under certain circumstances, the right to be paid dividends,
and liquidation and redemption rights before Series B preferred holders. The
Company accrued dividends payable of $615,151, $615,522 and $255,639 for the
years ended December 31, 1993, 1994 and 1995, respectively, on the Company's
Series A and B preferred stock and paid dividends of $522,043 in 1993 and
$612,665 in 1994. The remainder of dividends payable at December 31, 1994 was
accrued and paid in 1995 as well as the additional dividends in the amount of
$255,639.

     In November 1994, the Company issued 33,652 shares of its Series A common
stock and 34,340 shares of its Series B preferred stock to management of the
Company and three outside directors in exchange for $97,422, net of expenses of
$6,576.
 
     During the year ended December 31, 1995, the Company repurchased 1,233,136
shares of its Series B common stock for $123,314 and a stockholder contributed
15,544 shares of Series A common stock to the Company. Such shares of common
stock were subsequently retired by the Company.
 
     In a series of transactions on June 1, 1995, certain stockholders, who
owned approximately 73% of the Company, sold 3,143,097 shares of Series A and B
common stock and 7,618,392 shares of Series A and Series B preferred to new
investors who exchanged those shares for 3,982,568 shares of newly issued Series
C and Series D preferred stock. The Series C and D preferred shares issued and
outstanding at December 31, 1995 were 3,055,328 and 1,364,301, respectively. The
shares had a $.001 par value and a liquidation-preference of $5.72 per share at
December 31, 1995. Holders of the remaining shares of Series A common stock,
which represented approximately 27% of the Company's ownership including shares
received in the stock split described in Note 1, then exchanged their common
shares for newly issued shares of common stock. No change in accounting basis
was made as a result of this transaction. During the year ended December 31,
1995, $516,840 and $191,160 was accreted towards the Series C and Series D
liquidation preference using the effective interest method.
 
     In connection with these transactions, the Company, the new stockholders
and the other stockholders of the Company entered into a Stockholders Agreement
(the Stockholders Agreement) providing for, among other things, certain
restrictions on the transfer of shares of common stock or preferred stock,
rights of first refusal, and certain rights with respect to the repurchase of
such shares by the Company in the event of the death or total disability of the
holder thereof. Pursuant to the Stockholders Agreement, the new stockholders and
the other stockholders agree to vote their respective shares in a certain manner
in connection with the election of directors, including the directors elected
solely by the holders of the Series C convertible preferred stock. The
Stockholders Agreement terminated automatically upon the effective date of the
Company's initial public offering.
 
     The Series C preferred stockholders were entitled to receive dividends if
and when declared by the Board of Directors, were entitled to one vote for each
share of preferred stock subject to certain adjustments, had a liquidation
preference of $5.72 per share, and were convertible into shares of common stock
at the liquidation price per share subject to certain adjustments and were
mandatorily convertible upon an initial public offering of a certain size and
value. Such shares of preferred stock were mandatorily redeemable by the Company
at $5.72 per share in annual 25% increments beginning in 2001. Effective with
the Company's initial public offering in February 1996, each share of the Series
C preferred stock was converted to one share of common stock.
 
     The Series D preferred stockholders were entitled to the same rights and
privileges as the Series C stockholders except that they were not entitled to
vote, and they could convert their shares to Series C preferred shares under
certain circumstances. Such Series D shares were mandatorily convertible
ultimately into common stock upon the Company's initial public offering.
Effective with the Company's initial public offering in February 1996, each
share of the Series D preferred stock was converted to one share of common
stock.
 
     In October 1995, the Company sold 34,965 shares of common stock and 43,706
shares of Series C preferred stock to its President and raised net proceeds of
approximately $200,000 and $249,998, respectively, under an agreement entered
into in September 1995. Also during the year ended December 31, 1995, the
Company sold 43,707, 114,054 and 279,301 shares of its common stock, preferred C
and preferred D stock to a certain employee and a shareholder and raised net
proceeds of $230,799, $602,386 and $1,474,808, respectively.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     During the year ended December 31, 1996 the Company issued 2,300,000 shares
of common stock in its initial public offering, raising approximately
$25,633,607, net of expenses. Effective with the initial public offering all
3,055,328 shares of the Company's Series C preferred stock and all 1,364,301
shares of Series D preferred stock converted to one share each of the Company's
common stock. In addition, during the year ending December 31, 1996 the Company
issued 32,815 shares of its common stock under its Employee Stock Purchase Plan
and 34,250 shares of its common stock for exercises of stock options under the
1993 Stock Option Plan, for net proceeds of $153,410 and $27,690, respectively.
 
7.  401(K) AND PROFIT-SHARING PLAN
 
     The Company has a contributory profit-sharing plan which covers
substantially all of its employees. Effective July 1, 1993, the Company amended
its profit-sharing plan to include a 401(k) provision (the "401(k) Plan"). The
401(k) provisions in the 401(k) Plan allow eligible employees to contribute up
to 15% of their income on a tax-deferred basis, subject to IRS discrimination
and maximum dollar deferral rules. The Company, at its sole election, may make
matching contributions to the 401(k) Plan. The Board of Directors approved a
discretionary employer matching contribution of $.50 for each $1.00 the employee
contributes on the first 12% of compensation deposited as elective
contributions, subject to 401(k) Plan limitations and IRS regulations, for
calendar years 1994, 1995 and 1996. The Company's matching contributions vest to
employees at 25% per year for each full year of continuous service. The
Company's 401(k) matching expense was $158,441, $228,590 and $300,006 for the
years ended December 31, 1994, 1995 and 1996, respectively.
 
     The 401(k) Plan provides for an annual contribution to a self-directed
employee trust in an amount to be determined by the Board of Directors, but
limited to the amount allowable for income tax purposes. Employees may make
annual contributions to the 401(k) Plan of not more than 10% of their annual
compensation. The Company's contributions vest to the employees at 20% for the
first two years and 20% per year for years three through six for each full year
of continuous service, and are allocated based on employee compensation. The
Company had no profit-sharing expense for the years ended December 31, 1994,
1995 and 1996.
 
8.  STOCK BASED COMPENSATION PLANS
 
     At December 31, 1996 the Company had three stock options plans and an
employee stock purchase plan, which are described below. The Company accounts
for these plans in accordance with the provisions of Accounting Principles Board
Opinion No. 25, Accounting for Stock Issued to Employees, and related
Interpretations (APB 25). In October 1995, the Financial Accounting Standards
Board issued SFAS No. 123, Accounting for Stock-Based Compensation. As permitted
by SFAS No. 123, the Company has chosen to continue to account for its
stock-based compensation plans under APB 25 and provide the expanded disclosures
specified in SFAS No. 123. Accordingly, no compensation expense has been
recognized for its stock-based compensation plans.
 
     Had compensation cost been determined using the provisions of SFAS No. 123,
the Company's net income (loss) and income (loss) per share would have been
reduced to the pro forma amounts indicated below:

     For purposes of estimating the compensation cost of the Company's option
grants and employee stock purchase plan in accordance with SFAS 123, the fair
value of each option grant is estimated on the date of grant using the
Black-Scholes option-pricing model with the following assumptions used for
grants in the years

1996 and 1995, respectively: expected volatility of 67% and 0%; risk free
interest rate of 6%; and expected lives of 10 years for the 1993 Stock Option
Plan and the 1996 Stock Option Plan.
 
     Effective September 22, 1993, the Company adopted the 1993 Stock Option
Plan (the "Option Plan"), as amended, to permit executive personnel, key
employees and directors of the Company to participate in ownership of the
Company. The Option Plan is administered by a committee consisting of two or
more nonemployee directors of the Company. Each option agreement includes a
provision requiring the optionee to consent to the terms of the Agreement. The
Option Plan provides for the grant of incentive stock options under the
applicable provisions of the Internal Revenue Code or nonqualified options. In
October 1996 the Board of Directors approved non-officer employees holding
outstanding options to purchase 45,400 Common Shares of the Company at exercise
prices equal to or in excess of $12.87 to exchange such options for new options
at $6.00 per share, with the new options having a vesting schedule that
re-started on the date of the new option exchange grant. Up to 839,885 shares of
the Company's common stock were reserved for issuance under the Option Plan. The
following table summarizes activity under the Option Plan, as amended.

     The Company has reserved an aggregate of 150,000 shares of Common Stock for
issuance under its 1996 Employee Stock Purchase Plan (the "ESPP"). The ESPP was
adopted by the Board of Directors in January 1996 and approved by the Company's
stockholders prior to the consummation of the Company's initial public offering
in February 1996. The ESPP is intended to qualify under Section 423 of the
Internal Revenue Code of 1986, as amended, and permits eligible employees of the
Company to purchase Common Stock through payroll deductions of up to 10% of
their compensation provided that no employee may purchase more than $25,000
worth of stock in any calendar year. The ESPP was implemented by an offering
period commencing on February 14, 1996 and ending on the last business day in
the period ending October 31, 1996. Each subsequent offering period (an
"Offering Period") will commence on the day following the end of the prior
Offering Period and will have a duration of six months. The price of Common
Stock purchased under the ESPP will be 85% of the lower of the fair market value
of the Common Stock on the first or last day of each offering period. The ESPP
will expire in the year 2006. In the year ended December 31, 1996 the Company
issued 32,815 shares of Common Stock under the ESPP for $153,410. At December
31, 1996, $51,773 had been withheld from employee earnings for stock purchases
under the ESPP.
 
     For purposes of estimating the compensation cost of employees' rights under
the ESPP in accordance with SFAS 123, the fair value of the purchase rights has
been estimated using the Black-Scholes model with the following assumptions used
for 1996; expected volatility of 76%; risk free interest rate of 6%; expected
life of six months. The weighted-average fair value of those purchase rights
granted in 1996 was $4.68.
 
     The Company has reserved an aggregate of 60,000 shares of Common Stock for
issuance under its 1996 Director Option Plan (the "Director Plan"). The Director
Plan was adopted by the Board of Directors in February 1996. The Director Plan
provides for the grant of an option to purchase a number of shares of Common
Stock (the "First Option") to be determined by the incumbent Board of Directors
to each non-employee director who first becomes a non-employee director after
the effective date of the Director Plan. Annually, each outside director shall
automatically be granted an option to purchase 4,000 shares (a "Subsequent
Option"), provided he or she is then a non-employee director and, as of such
date, he or she shall have served on the Board for at least the preceding six
months. Each non-employee director will be eligible to receive a Subsequent
Option, regardless of whether such non-employee director was eligible to receive
a First Option. First Options and each Subsequent Option will have a term of ten
years. One-quarter of the shares subject to a First Option will vest one year
after their date of grant and an additional one-quarter will vest at the end of
each year thereafter, provided that the optionee continues to serve as a
director on such dates. Similarly, one-quarter of the shares subject to a
Subsequent Option will vest one year after the date of the option grant and an

the Borrower will comply with all of the following covenants:

3.1      Corporate Existence and Authority. The Borrower, if a corporation, is
and will continue to be, duly authorized, validly existing and in good standing
under the laws of the jurisdiction of its incorporation. The Borrower is and
will continue to be qualified and licensed to do business in all jurisdictions
in which any failure to do so would have a material adverse effect on the
Borrower. The execution, delivery and performance by the Borrower of this
Agreement, and all other documents contemplated hereby have been duly and
validly authorized, are enforceable against the Borrower in accordance with
their terms, and do not violate any law or any provision of and are not grounds
for acceleration under, any agreement or instrument which is binding upon the
Borrower.

3.2 Name; Trade Names and Styles. The name of the Borrower set forth in the
heading to this Agreement is its correct name. Listed on the Schedule hereto
are all prior names of the Borrower and all of Borrower's present and prior
trade names. The Borrower shall give Silicon 15 days' prior written notice
before changing its name or doing business under any other name. The Borrower
has complied, and will in the future comply, with all laws relating to the
conduct of business under a fictitious business name.

33 Place of Business; Location of Collateral The address set forth in the
heading to this Agreement is the Borrower's chief executive office.  In

executive office or locating the Collateral at any other location *.  *
, other than for certain office, computer and demonstration equipment
temporarily located outside of offices of the Borrower for use by employees or
customers of Borrower.

3.4      Title to Collateral; Permitted liens. The Borrower
is now, and will at all times in the future be, the sole owner of all the

security interests, encumbrances and adverse claims, except for the following
("Permitted Liens"):  (i) purchase money security interests in specific items
of equipment; (ii) leases of specific items of equipment; (iii) liens for taxes
not yet payable; (iv) additional security interests and liens consented to in
writing by Silicon in its sole discretion, which consent shall not be
unreasonably withheld; and (v) security interests being terminated
substantially concurrently with this Agreement. Silicon will have the right to
require, as a condition to its consent under subparagraph (iv) above, that the
holder of the additional security interest or lien sign an inter-creditor
agreement * acknowledge that the security interest is subordinate to the
security interest in favor of Silicon, and agree not to take any action to
enforce its subordinate security interest so long as any Obligations remain
outstanding, and that the Borrower agree that any uncured default in any
obligation secured by the subordinate security interest shall also



<PAGE>   4
constitute an Event of Default under this Agreement. Silicon now has, and will
continue to have, a perfected and enforceable security interest in all of the
Collateral, subject only to the Permitted Liens, and the Borrower will at all
times defend Silicon and the Collateral against all claims of others. None of
the Collateral now is or will be affixed to any real property in such a manner,
or with such intent, as to ** become a fixture *        that is acceptable to
Silicon in its discretion

**       , except for any leasehold improvements that Borrower has made to its
leasehold premises

3.5      Maintenance of CollateraL The Borrower will maintain the Collateral in
good working condition, and the Borrower will not use the Collateral for any
unlawful purpose. The Borrower will immediately advise Silicon in writing of

Borrower's obligation to pay the taxes by appropriate proceedings promptly and
diligently instituted and conducted, (ii) notifies Silicon in writing of the
commencement of, and any material development in, the proceedings, and (iii)
posts bonds or takes any other steps required to keep the contested taxes from
becoming a lien upon any of the Collateral. The Borrower is unaware of any
claims or adjustments proposed for any of the Borrower's prior tax years which
could result in additional taxes becoming due and payable by the Borrower. The
Borrower has paid, and shall continue to pay all amounts necessary to fund all
present and future pension, profit sharing and deferred compensation plans in
accordance with their terms, and the Borrower has not and will not withdraw
from participation in, permit partial or complete termination of, or permit the

liability to the Pension Benefit Guaranty Corporation or its successors or any
other governmental agency.  *        in all material respects

any material impairment in the ability of the Borrower to carry on its business
