ITEM 1. BUSINESS

Introduction

  We design, manufacture, market, install and support communication and
information systems, using wireless and internet technology and proprietary
software to allow access to health information, including patient vital signs
and other diagnostic data, using wireless technology and proprietary software.
Our systems provide for information retrieval from remote sources, both inside
and outside the hospital environment, and are integrated and coordinated
through either a wireless network utilizing our interactive device, a personal
computer or the internet. Our focus within health care is on the hospital,
physician and at-home consumer markets.

Industry Background

  Recent technological advances in digital wireless communications and the
demands of an increasingly mobile workforce have resulted in the proliferation
of wireless hand-held information communication devices. The capabilities of
these sophisticated devices, which include personal digital assistants,
wireless receivers and smart phones, often with access to the internet, are
fostering the development of information-intensive applications than can
result in greater caregiver productivity and efficiency. At the same time,
healthcare facilities, including hospitals and extended care facilities, are
focused on reducing costs and enhancing workforce productivity. These
facilities are seeking to improve the response time, decision-making quality
and overall efficiency of caregivers, including physicians and nurses, who
treat patients in life-critical situations.

 Dynamics of Healthcare Industry

  Large Market with Need for Reduced Costs. According to the Health Care
Financing Administration (HCFA), healthcare is estimated to be the largest
single sector of the U.S. economy in 1999, representing approximately $1.2
trillion, or 14% of the U.S. gross domestic product. According to data from
the American Hospital Association, in 1997 there were 6,097 hospitals and
1,035,890 hospital beds in the United States. Inefficiencies within the
healthcare system consume significant time, resources and capital. During
1998, an estimated $250 billion, or 25% of every healthcare dollar, was spent
on excessive administrative costs, the delivery of unnecessary care and
performance of redundant tests and procedures. One responsive measure taken by
the government and managed care companies has been to impose restrictions on
hospital admittance and

                                       3
<PAGE>

reimbursement. This has resulted in higher levels of acuity and a lower number
of patients being treated in an inpatient environment, each requiring closer
monitoring in order to maintain an appropriate level of care.

  Aging of the Population. Rapid growth in the aged population is expected as
the baby boomers move into the elderly population group. According to the U.S.
Census Bureau, the 75+ age group is expected to grow from 13.2 million in 1990
to over 16.6 million by the year 2000. The population of seniors age 85+ is
expected to increase from 3.1 million in 1990 to 4.3 million by the year 2000.
As the proportion of the population which is elderly increases, the average
age of hospital patients increases as well. Since the elderly are more
susceptible to complications while hospitalized, monitoring of their vital
signs is critical to ensure against unforeseeable adverse events.

  Migration of Patients to Less Costly Care Environments. In response to
escalating healthcare costs, government and private pay sources have
implemented cost-containment measures designed, when appropriate, to migrate
post-acute patients more quickly from higher intensity care, high cost units
such as intensive care units to lower intensity care, lower cost units such as
step-down units. These patients continue to require monitoring even though
they have been moved to a lower cost setting which has a much lower nurse-to-
patient ratio. Hospitals spend significant capital to upgrade their monitoring
equipment to accommodate the level of care required by these patients. Due to
this trend of moving patients out of critical areas of the hospital sooner,
hospitals are converting more of their general medical/surgical beds to step-
down or patient-monitoring units.

  Underdeveloped Communications Technology in Hospitals. Underdeveloped
information systems and communications procedures within hospitals,
specifically relating to critical care patient information, contribute to
inefficiencies and high cost in the healthcare industry. Caregivers must
attend to several patients in various locations while simultaneously accessing
time-critical patient medical information that is monitored and collected by
medical equipment. Within hospitals, patients are monitored by medical
equipment that either is centrally connected or operates on a stand-alone
basis. According to Frost and Sullivan, the worldwide hospital monitoring
equipment market, which includes cardiac, respiratory, blood gas, and
neurological monitoring equipment, is estimated to be approximately $6.4
billion in 1999. The large number of medical monitoring devices in each
hospital and the fact that these devices are manufactured by numerous medical
equipment suppliers has hampered the ability of many hospitals to create
integrated critical care patient communications networks. While most hospitals
operate in a decentralized nurse mode, the information from medical equipment
is available only at a central location. Consequently, most hospitals employ
monitoring technicians to centrally monitor critical care patient data
captured by medical equipment and inform caregivers when problems arise. This
method of communicating critical care information is time-consuming, costly
and can adversely impact the care of patients requiring immediate attention.
Due to these conditions, neither monitoring technicians nor caregivers within
hospitals are able to attend to other vital stand-alone medical equipment on a
regular basis.

  Growth of Wireless Communications. In recent years, the proliferation of
wireless communications solutions has extended the reach and connectivity of
mobile professionals. For example, in voice communications, cellular
telephones have enabled mobile users to place phone calls from virtually any
location. Similarly, advances in wireless data communications, including
wireless local area networks (LANs) and radio modems, have enabled the
extension of enterprise networks to the notebook computers and handheld
information communication devices of mobile users. The projected growth of
wireless data communications systems, driven by increasing connectivity
options for mobile users, will result in increased accuracy, timeliness and
convenience of information access, thereby reducing costs and improving
productivity. Frost & Sullivan expects revenue from wireless data services to
triple to more than $9 billion in 2000 from an estimated $3 billion in 1997.

  The Internet as a Critical Healthcare Information Tool. The internet, with
its open architecture and broadening availability at home, in the workplace
and at the point of care, makes it possible for physicians to document
physician-patient encounters and manage clinical information. In addition,
consumers are seeking more information in order to actively manage their
personal health and wellness. As a result, many consumers are turning to the
internet to obtain health information. According to Cyber Dialogue, an
industry research firm, during 1998, approximately 22 million adults in the
United States searched online for health and medical

                                       4
<PAGE>

information. In addition, Cyber Dialogue estimates that in the year 2000, the
number of adults in the United States searching for online health and medical
information will grow to approximately 33 million, and they will spend
approximately $150 billion for all types of health-related products and
services. Cyber Dialogue also estimates that approximately 70% of the persons
searching for health and medical information online believe the internet
empowers them by providing them with resourceful information to make better
informed health decisions. Over the past decade, the healthcare industry has
changed radically as employers seeking to reduce their healthcare costs have
turned from indemnity insurance to managed health plans. Approximately 180
million people, or 90% of the insured U.S. population, have some form of
managed care. We believe that consumers increasingly question the motivations
of their caregivers and are more inclined to take an active role in the
decisions that affect their health and wellness as well as that of their
families.

The Data Critical Solution

  Data Critical's systems extend the power of wireless technology to the
healthcare industry by employing a suite of hardware and software systems that
transmit complex time-critical data over wireless networks and through the
internet. Our systems improve communications and decision-making for
physicians and nurses both in the hospital and in remote locations, thereby
improving the delivery of patient care and reducing healthcare costs.

  Our solution provides the following key benefits:

  Increased Work Efficiency. Our hospital systems extend a hospital's existing
patient-monitoring capability by allowing caregivers to remotely monitor
critically-ill patients and communicate on a near-immediate basis. By
gathering data from a broad array of patient-monitoring and other medical
equipment and distributing that data to a wireless communications device,
caregivers can monitor patient conditions while continuing to perform tasks
elsewhere. When there are adverse changes in a particular patient's condition,
caregivers are immediately alerted. Alarms can then be automatically and
simultaneously transmitted to individual nurses, physicians or other
caregivers. Our physician systems enhance work efficiency for physicians by
offering health record products and services for use at the point of care to
create and access vital patient data.

  Improved Quality of Care. Our systems are designed to provide critical
patient information on a near-immediate basis directly to caregivers in and
out of the hospital. This near immediate delivery of information allows for
more rapid response times with better information. Our products allow
hospitals and physicians to maintain or improve quality of care, especially in
light of the current trend of declining caregiver-to-patient ratios.

  Reduced Costs. Most hospitals employ technicians with the responsibility to
monitor patient data from central locations. Those hospitals that use
monitoring technicians generally employ one to two full time equivalents per
nursing station. Our systems reduce the need for hospitals to maintain large
staffs of monitoring technicians. We believe that in many situations hospitals
can realize full return on their investment within 12 months of purchasing our
systems simply through the redeployment of these hospital personnel.

  Ease of Use. We have designed our receivers based on feedback from
healthcare professionals that dictated operational simplicity and hand-held
form factors. Device operation is rapidly learned. We believe that our design
features allow our customers to quickly and easily deploy our systems without
requiring extensive or technical training.

  Open Architecture. Our systems are designed to interface with numerous hand-
held devices and with medical equipment manufactured by numerous medical
equipment suppliers. By providing a standard, scalable system we can interface
with the medical equipment that is already deployed in hospitals. In addition,
the ability of our systems to operate with other similar medical equipment
allows us to partner with various manufacturers.

  Security and Confidentiality. Certain of our systems include strict
authentication methods and data encryption technology. These security features
allow for the exchange of confidential patient information without

                                       5
<PAGE>

that information being compromised. In addition, our Wireless Telemedicine
(WT) Server software provides access to the proprietary network software of
our strategic partners' patient monitoring systems.

Our Strategy

  Our objective is to be the leader in providing wireless health information
communications systems to mobile caregivers who depend upon the interactive
transmission of complex and time-critical data. The principal elements of our
strategy include the following:

  Increase Hospital-Based Penetration and Generate Follow-On Sales
Opportunities. The initial target market for our hospital systems includes
approximately 5,000 hospitals, and 18,000 cardiology-related departments in
the U.S. for our StatView, AlarmView and FlexView systems. We have multiple
placement opportunities in various areas throughout the hospital, including
critical care units, step-down units, emergency rooms, telemetry units and
obstetrics. Since commencing distribution of our systems in late 1997, we have
installed our systems in over 130 U.S. hospitals. We intend to increase our
market penetration in major U.S. hospitals by building upon the existing
installed base of products manufactured by our strategic alliance partners.
Once we have introduced our systems to a hospital and have demonstrated the
benefits of these systems to healthcare professionals, we plan to sell our
systems to other areas of practice within that hospital. In addition, we plan
to integrate our AlarmView technology into stand-alone monitoring equipment
such as pulse oximeters, multi-parameter monitors, ventilators, IV pumps and
defibrillators. We estimate that there are over 1 million stand alone monitors
in the U.S.

  Pursue Additional Strategic Alliances and Acquisitions. We are continuing to
pursue additional strategic alliances and acquisitions that will augment or
expand our distribution channels and system offerings. A major emphasis will
be to broaden the physician-based side of our business through both
partnerships and acquisitions. Additionally, we are pursuing additional
partners for our AlarmView system. We distribute our systems through our
direct sales force and our relationships with leading vendors of complementary
medical equipment. We expect to build upon the expertise we gain through our
strategic alliances to facilitate additional alliances and move into new
markets. We will continue to review mutually beneficial opportunities to share
new technologies, including cross-licensing opportunities. We also intend to
enter into strategic relationships with one or more internet portals and other
web-based healthcare companies to promote the use of our Internet ECG system
and DataView system.

  Pursue Physician-Based Strategy of Wireless Internet-Based Connectivity for
Healthcare. We plan to deliver a set of applications including patient
charting, billing, prescription filling and laboratory ordering and results
reporting for our physicians using handheld wireless devices. We will continue
to add functionality and architect our systems to take advantage of our core
wireless and internet capabilities. Our delivery will allow physicians to
effectively manage their patients in hospitals and clinics wherever they may
be using the latest generation of wireless and computing devices. This added
functionality will allow both reduction of costly errors as well as the
ability for physicians to expand their practices and improve their revenues.

  International Expansion. We intend to expand sales of our systems into
international markets, including Europe and Japan. The international
healthcare market makes use of similar networked and stand-alone monitoring
devices and has similar scope to that of the U.S. healthcare market. We
believe that there may be significant demand for our systems in international
markets because hospitals outside the U.S. are even less equipped with remote
monitoring and interconnectivity systems than U.S. hospitals. We intend to
build upon our existing strategic alliances through their dealer and
distributor organizations to further our international expansion strategy.

  Expand Use of the Internet to Link Physicians and At-home Consumers. Through
our physician-based toolset, we expect to expand our ability to rapidly
provide complex data to these users. We believe that many of our existing
technologies for the efficient transmission of data, as well as technology
acquired from Physix, Inc.

                                       6
<PAGE>

and Elixis, Inc., may have broad applications for hospitals, physicians and
patients seeking to access and deliver information from and to remote
locations through either wireless or wired devices linked to the internet. We
have developed core technology, including Internet ECG, to address the need to
transmit medical information from homes through the internet.

  Maintain and Build on Technology Leadership. We are a technology leader in
providing for the communication of complex healthcare data through wireless
systems and networks. To strengthen and extend our communications solutions,
we plan to continue investing in research and development to expand the
features and functionality of our systems. For example, future systems may
extend the remote communications network to other types of medical equipment,
like infusion pumps, ventilators, incubators, medical information systems,
smart beds, nurse call devices and home care devices. In addition, we may
apply our technology to other industries where the rapid communication of
detailed information is critical and where the mobility of end users is key,
including law enforcement or other government services.

Our Systems

  We design our systems to address the needs of the healthcare industry.
Caregivers are highly dependent on access to complex and time-critical data
and benefit greatly from the rapid transmission of data.

 StatView

  The StatView system is a local wireless system that alerts nurses when
alarms from patient-monitoring systems are triggered. The StatView system
connects to an existing patient-monitoring network, collects alarm

                                       7
<PAGE>

data from these monitors and transmits ECGs, vital signs and other patient
information as graphic representations in the shape of waves through a
dedicated wireless transmitter to a StatView receiver unit worn by the nurse.
Alarm events can be transmitted automatically to individuals or groups and
periodic updates can be transmitted to the appropriate caregivers. Nurses
using the StatView system carry a compact graphic wireless receiver that
sounds alarm tones or vibrates whenever a patient monitor generates an alarm.
The receiver then displays bed number, patient name, diagnosis (i.e.
ventricular tachycardia), heart rate, and, with one button click, a six second
ECG graphic. By looking at the ECG, nurses can determine the urgency of the
alarm and be informed prior to reaching a patient's bedside.

 MobileView ECG Stat

  MobileView ECG Stat transmits data that is collected by the StatView system
from individual patient monitors to physicians or other caregivers at remote
locations usually outside of the hospital. The MobileView ECG Stat System uses
digital wireless technology on a wide area network to provide caregivers with
immediate remote access to critical patient information, including multiple
ECGs, vital signs parameters and graphics and nurse notes. Physicians can
access this information through a portable, wireless hand-held device or
through a website that uses our DataView system. MobileView ECG Stat is
designed to be easily integrated into a wide variety of monitoring equipment
and is compatible with our StatView system.

  The MobileView ECG Stat system has the following key features and benefits:

  .  delivers quality graphics and other patient data to remote locations;

  .  enables faster clinical consultation and decision making;

  .  transmits data securely;

  .  integrates with StatView; and

  .  provides a dial-up, wireless connection to the patient-monitoring
     network.

 DataView

  Our DataView system allows physicians to review data collected by StatView
systems through a website.

 AlarmView

  AlarmView is a wireless system that is designed to connect to stand-alone
devices to create a virtual monitoring network. AlarmView attaches to the back
of non-networked patient monitors, infusion pumps and other intelligent
devices and can deliver near immediate alarms and other information to
wireless receivers in less than ten seconds. The information from AlarmView
transmitters can be sent to the same StatView receivers already worn by
caregivers. As the volume of patient admissions changes, the AlarmView
transmitter can be easily transferred to devices manufactured by multiple
vendors without requiring costly and time-consuming setup since AlarmView is
designed to automatically interface upon connection. Our AlarmView system
received approval by the FDA in November 1999, and we expect to begin
commercial sales of AlarmView systems in the second quarter of 2000.

 FlexView

  The FlexView system integrates disparate information from stand-alone
patient devices into a single patient view at the nurses' station facilitating
the monitoring of patient data and trends, alarms and device operational
status. With simple mouse clicks, the display provides nurses with a
department-wide overview, as well as individual patient or device status
views. The system can link up to ten devices per patient for as many as 40
patients.

  We plan to deliver a set of applications including patient charting,
billing, prescription filling, and laboratory ordering and results reporting
for our physicians using wireless web-based handheld devices. In December 1999
we acquired the assets of Physix Inc., which was selling Compendia and
PocketChart. Compendia serves the small to large physician group market by
providing a networked charting and clinical information system that is
designed to scale from a single group practice to a multiple site enterprise
and automating patient data collection services for emergency medical
technicians in the field. PocketChart serves the academic medical training
programs and medical student market by providing a stand-alone, mobile point-
of-care electronic medical record as the first step to the network Compendia
system.

  We intend to use the core Compendia technology to develop our wireless web-
based physician tools in conjunction with the technology and products that
will be acquired through our acquisition of Elixis, Inc.

Consumer System

 Internet ECG

  We have completed development of the initial release of our Internet ECG
system, which is designed for consumers to view their own ECGs and review them
through an application downloaded via the internet. Through a proprietary
hand-held device, the consumer would be able to relay heart rate and ECG
graphic information via a personal computer's microphone to a website running
our software. The website would then relay additional biofeedback, exercise
training data and personal educational information back to the consumer almost
simultaneously. Our Internet ECG system is not yet commercially available. We
intend to pursue agreements with internet portals and other web-based
healthcare companies for distribution of this system.

 The Wireless Telemedicine (WT) Server

  Our StatView and MobileView ECG Stat systems depend on our WT Server, which
is designed to collect, compress and encrypt critical patient data for
transmission to individual handheld devices through wireless networks. The WT
Server combines an Intel server running Microsoft NT with our proprietary
technology, which is designed to ensure secure and rapid transmission of
confidential patient information.

  The WT Server has the following key features and benefits:

  .  compatible with the leading patient monitoring systems;

  .  internet browser-based system administration;

  .  allows multiple concurrent wireless connections;

  .  radio frequency transmitter provides unit coverage area; and

  .  modem interface with digital wireless networks.

Strategic Alliances

  We have entered into strategic alliances with manufacturers of medical

the performance of any material provision.

Customers and Markets

  Data Critical currently focuses on the healthcare industry because of the
critical need of healthcare professionals to have immediate access to time-
critical patient data. Our target customers include hospitals and physicians
primarily across the U.S., and to a lesser extent in Canada and Europe. We
believe that these groups would benefit from using our systems by reducing
costs and increasing productivity. Our target markets also include aggregators
of individual physicians including large medical groups, independent practice
associations, physician practice management companies and other large
organized physician entities. We also target physicians who practice outreach
telemedicine. Additionally, we believe that specialist physicians with
patients who require immediate medical attention upon sudden change in medical
status, such as cardiologists, nephrologists, obstetricians and gynecologists,
would benefit from using our products. Although currently our products are
only being used by hospitals and physicians, we are targeting our Internet ECG
product to the at-home consumer market. Below is a summary of our target
domestic markets and end users:

Sales, Marketing and Customer Support

  We market and sell our systems both through direct marketing and sales
programs and through OEM relationships with our strategic partners. We
currently have 15 sales territories in two regions supported by four telephone
direct sales account managers. In addition, our strategic partners provide
field sales people who actively sell and market our StatView and MobileView
ECG Stat systems to their respective accounts. We carefully select our
strategic partners and work closely with them throughout their sales process
to increase our revenue potential. We maintain direct co-marketing
relationships with several of our partners, which allow us more control and
flexibility over the sales and marketing process of our systems.

  We also directly target physicians and large medical groups for our
physician handheld tools and nurses and nursing professional associations for
StatView. We maintain an extensive, online database of all U.S. hospitals that
is updated quarterly. This database is a key source of sales information
covering capital equipment purchase cycles, key decision makers and the status
of all contacts made at the account.

  We attend and showcase our systems at major trade shows, including those
sponsored by the American Heart Association, the Association of Nurse
Executives, the Healthcare Information Management Systems Society and the
Society of Critical Care Medicine. At many of these trade shows, we co-promote
our products in our strategic partners' booths. We also send direct mailings
to potential customers promoting our systems, and support the external
research efforts of institutions that are reviewing technology uses within the
healthcare industry.

  We believe that a high level of customer support is necessary to achieve
wide acceptance of our systems. We provide customer support services twenty-
four hours a day, seven days a week. We employ technical support personnel who
work directly with our direct sales force, strategic partners and customers.
We also provide training programs for our customers.

Manufacturing

  Our manufacturing operations consist primarily of final assembly and
testing, quality assurance, packaging and shipping. Our current manufacturing
facility is located in Bothell, Washington. Our Bothell facility is regulated
by the FDA and must undergo periodic audits for compliance with the FDA's
quality system regulations. In September 1999, we were certified for ISO 9001
and EN46001 Certification to the U.S. Registrar Accreditation Board. ISO 9001
is the highest level of certification for quality manufacturing in the U.S.
and EN46001 Certification requires meeting additional quality standards in
order to manufacture medical devices sold in Europe.

  We currently rely on outside contract manufacturers for certain components
of our systems. We purchase standard server hardware directly from third party
manufacturers and install our proprietary software on these servers. We have
developed a supplier selection procedure and approved vendor list to maintain
quality. In addition, we monitor our suppliers' performance to ensure
consistent quality, reliability and yield.

Research and Development

  The emerging market for the use of wireless communications and the internet
in the healthcare industry is characterized by rapid technological
developments, frequent new product introductions and evolving industry
standards. Advances in operating systems, radio frequency systems and hardware
are enabling the rapid proliferation of new solutions.

  Through our research and development efforts, we strive to use the most
current technology to ensure that we provide systems that meet the needs of an
ever-changing marketplace. We believe that our future success will depend in
large part on our ability to continue to maintain and enhance our software
applications, wireless technologies and other proprietary technology while
simultaneously improving the performance, features and reliability of our
systems.

                                      12
<PAGE>

  The success of our new system introductions will be dependent on several
factors, including:

  .  identification of a realizable market opportunity;

  .  definition of new systems;

  .  timely completion and introduction of new systems; and

  .  market acceptance of our systems.

  To enable us to develop new systems more rapidly, we intend to leverage the
modular nature of our system architecture. In addition, we intend to rely on
our alliances with strategic partners for additional research and development
resources to create solutions that interface with their products.

  For the twelve months ended December 31, 1999, 1998, and 1997, expenses
attributable to research and development totaled $2.5 million, $2.2 million,
and $1.7 million, respectively. We believe that the timely development of new
and enhanced systems and technologies is necessary to remain competitive in
the marketplace. Accordingly, we intend to continue recruiting and hiring
experienced development personnel, as well as making other investments in
research and development.

Competition

  Our hospital systems compete primarily with traditional methods of patient
monitoring, including direct patient oversight, monitoring through wired
systems and voice communications. If we are successful in establishing a need
for our systems, we expect that additional entrants will be drawn into our
market. In addition, there is the possibility that one or more of our
strategic partners or other medical equipment manufacturers may decide to
develop products that directly compete with our systems. For example, in
January 2000, Spacelabs Medical, Inc. announced that it received notification
of FDA 510(k) clearance to market its new Ultraview Clinical Messenger(TM), a
multi-parameter waveform wireless paging system. Spacelabs has stated its
plans to sell the product to hospitals that have Spacelabs patient monitors.
We may have difficulty competing with these potential competitors because many
of them may have longer operating histories, significantly greater resources,
better name recognition and a larger installed base of products and
technologies.

  Our physician systems are subject to competition from both traditional
healthcare information system vendors and internet healthcare companies. The
internet healthcare industry is intensely competitive and subject to
fragmentation, high growth and rapid technological change. Many of these
companies have significantly greater financial resources, well-established
brand names and large installed customer bases. We may be unable to compete
unsuccessfully against these organizations.

  Our systems compete on the basis of cost-efficiency, enhanced mobility,
features, functionality and price. We believe we compete favorably with regard
to each of these factors.

  To maintain and improve our competitive position, we must:

  .  continue to prove the benefits of our systems;

  .  develop new and improved technologies;

  .  market to hospitals, healthcare professionals and consumers; and

  .  maintain and continue to create alliances with key manufacturers of
     complementary medical equipment.

Patents and Intellectual Property Rights

  We rely on a combination of patent, copyright, trademark and trade secret
laws and other agreements with employees and third parties to establish and
protect our proprietary rights. Currently, we own three patents, two of which
were filed with the U.S. Patent and Trademark Office (PTO) in 1993 and one of
which was filed with the PTO in 1996. We also have one pending patent
application that was filed with the PTO in 1996. We license two patents, filed
with the PTO in 1991 and 1995, and certain trade secrets and other
intellectual property rights

                                      13
<PAGE>

from third parties. The duration of patents filed with the PTO is 20 years
from the date of filing. Our patents cover specific technology related to the
wireless transmission of graphics. Our strategic partners have also disclosed
and/or licensed to us source code or output protocols, which are proprietary
to their medical equipment and monitoring systems. We believe that no other
company in our industry currently has the access to the breadth of medical
monitoring equipment and source/output code that we do.

  We require each of our officers, employees and consultants to enter into
standard agreements containing provisions requiring confidentiality of
proprietary information and assignment to us of all inventions made during the
course of their employment. We also enter into nondisclosure agreements and
limit access to and distribution of our software, documentation and other
proprietary information.

  Despite our efforts to protect our proprietary rights, unauthorized parties
may attempt to copy aspects of our systems or may independently develop
technologies that are substantially equivalent to ours. We cannot be certain
that our patent application will be allowed or that our existing patents will
be held valid and enforceable by a court if we desire to enforce them. In
addition, employees or other parties may breach confidentiality agreements or
other contracts we have entered, and we may not be able to effectively enforce
our rights in the event of breaches.

Government Regulation

  Federal Communications Commission. In the U.S., we are regulated by the FCC.
The FCC requires that wireless access devices meet various standards,
including safety standards regarding human exposure to electromagnetic
radiation and basic signal leakage. The FCC has approved our radio frequency
system components. In addition, we currently hold an FCC license on 26
frequencies in the UHF spectrum. We are also regulated under the
Telecommunications Act of 1996 and other federal, state and international laws
and regulations. Additional laws and regulations may also be adopted
concerning wireless communications networks covering issues like user privacy
and quality of products and services. The adoption of any additional laws or
regulations, or our failure to comply with existing laws and regulations, may
impede the growth of wireless communications networks, decrease the demand for
our systems and have a material adverse effect on our revenue and sales.

  Food and Drug Administration. The FDA is responsible for assuring the safety
and effectiveness of medical devices under the Federal Food, Drug and Cosmetic
Act. Our StatView, MobileView ECG Stat, AlarmView and FlexView systems are
regulated by the FDA because they have been defined as medical devices used in
the diagnosis and treatment of disease. Under FDA regulations, medical devices
are classified into one of three classes on the basis of the controls deemed
by the FDA to be necessary to reasonably ensure their safety and
effectiveness: Class I, Class II and Class III. Class I requires only general
controls including labeling, pre-market notification and adherence to good
manufacturing practices. Class II requires general and specific controls
including performance standards and post-market surveillance. Class III
requires pre-market approval by the FDA. The FDA has classified our StatView
system as a Class III product.

  MobileView ECG Stat is currently classified as a Class II product,
grandfathered under the Agilent Technologies PalmVue classification. Our
AlarmView system received FDA approval as a Class III product during November
1999. Before we can market systems that are classified as Class III products,
we must obtain pre-market notification clearance under Section 510(k) of the
Federal Food, Drug, and Cosmetic Act. In addition, material changes to our
systems may also require FDA review and clearance prior to marketing or sale
in the U.S. The FDA will typically grant 510(k) clearance if we can establish
that our device is "substantially equivalent" to a legally marketed Class I or
II medical device or to a Class III device for which the FDA has not yet
required the submission of a pre-market approval application.

  The process of obtaining 510(k) clearance can be expensive and time-
consuming, and may require the submission of extensive supporting data. If we
fail to obtain 510(k) clearance for any of our new or modified systems, or if
the 510(k) process is extended for a considerable length of time, the
commencement of commercial sales of these systems will be delayed
substantially or indefinitely.

                                      14
<PAGE>

  Healthcare Regulations. Because we are a provider of healthcare related
systems, extensive and frequently changing federal regulations also govern the
licensing, conduct of operations and other aspects of our business. Federal
certification and licensing programs establish standards for day-to-day
operation of our research and manufacturing facilities. Regulatory agencies
verify our compliance with standards through periodic inspections and required
participation in proficiency testing programs. Although we have been found to
be in compliance with all these standards to date, our facilities may not pass
future inspections conducted to ensure compliance with federal or any other
applicable licenses or certification laws.

  Patient Medical Record Confidentiality Laws. The confidentiality of patient
records and the circumstances under which records may be released for
transmission through our systems are substantially regulated by state
governments. These state laws and regulations govern both the disclosure and
the use of confidential patient medical record information. Although
compliance with these laws and regulations is at present principally the
responsibility of the hospital, physician or other healthcare provider,
regulations governing patient confidentiality rights are evolving rapidly.
Additional legislation governing the dissemination of medical record
information has been proposed at both the state and federal level. This
legislation may require holders of confidential patient information to
implement security measures that could require substantial expenditures.
Changes to state or federal laws could materially restrict the ability of
healthcare providers to transmit information from patient records using our
systems.

  Health Insurance Portability and Accountability Act of 1996. The Health
Insurance Portability and Accountability Act of 1996 mandates the use of
standard transactions and identifiers, prescribed security measures and other
provisions within two years after the adoption of final regulations by the
Department of Health and Human Services. It will be necessary for our products
and services to be in compliance with the proposed regulations. Congress is
also likely to consider legislation that would establish rules about
individuals' rights to access their own or someone else's medical information
within legislation known as a patient bill of rights. This legislation, if
enacted, would likely define what is to be considered protected health
information and outline steps to ensure the confidentiality of this
information.

  In October 1999, the Department of Health and Human Services proposed new
rules under the Health Insurance Portability and Accountability Act of 1996.
The proposed rules would require the formulation of policies and systems that
give individuals access to their health information. In addition, these rules
would require that safeguards be constructed to protect this health
information against unauthorized access. The proposed rules include new
penalties for violations of an individual's right to keep her health
information private. These proposed rules are expected to become final in
2000.

  Laws and Regulation of the Internet. There are currently few laws or
regulations that specifically regulate communications or commerce on the
Internet. However, laws and regulations may be adopted that address issues
such as online content, user privacy, pricing and characteristics and quality
of applications and services. For example, although two key provisions of the
act were held unconstitutional, the Communications Decency Act of 1996
prohibited the transmission over the Internet of some types of information and
content.

  Internet user privacy has become an issue in the United States. Current
United States privacy law consists of a few disparate statutes directed at
specific industries that collect personal data, none of which specifically
covers the collection of personal information online. The United States or any
state may adopt legislation to attempt to protect this privacy. Any
legislation addressing these issues could affect the way in which we are
allowed to conduct our business, especially those aspects that involve the
collection or use of personal information, and could have a material adverse
effect on our business, financial condition and results of operations.
Moreover, it may take years to determine the extent to which existing laws
governing issues such as property ownership, libel, negligence and personal
privacy are applicable to the Internet.

  International regulations concerning the Internet, privacy and transborder
data flows are considerably more developed than regulations in the United
States. We intend to develop applications and services to be used on a
worldwide basis and, consequently, will be required to comply with
international regulations concerning the

                                      15
<PAGE>

Internet and e-commerce, as well as with U.S. regulations. We have not
evaluated the effect that these regulations would have on our business. These
regulations also may have an adverse effect on our ability to compete
internationally.

Recent Acquisitions

  Physix, Inc. In December 1999 we acquired substantially all of the business,
assets and rights of Physix subject to some of its debts in exchange for
200,000 shares of our common stock and approximately $1.5 million in cash. We
believe the transaction will enable us to combine the wireless technology of
our StatView, AlarmView and MobileView products with Physix's workflow
applications to create an internet-based application that can further improve
productivity and reduce caregiver expenses.

  Elixis, Inc. In March 2000 we signed a definitive agreement to acquire all
of the outstanding shares of stock of Elixis through a merger with our wholly
owned subsidiary. The transaction is expected to close in April 2000, subject
to approval by Elixis' shareholders and the satisfaction of other conditions.
We believe that Elixis' technology, when combined with the technology we
acquired from Physix, will accelerate our ability to create wireless,
internet-based clinical systems. We also plan to take advantage of Elixis'
distribution partnerships with leading healthcare companies, such as Baxter
Healthcare Corporation and Boston Scientific, its strategic alliances with
drugstore.com, CVS.com, Physicians Online, HealthStream and MD Consult and its
hospital customers, such as the University of Washington Medical Center and
the University of Pennsylvania Health System.

Employees

  As of December 31, 1999, we had 86 employees, including 8 in manufacturing,
28 in sales and marketing, 14 in services and support, 19 in research and
development, 3 in regulatory affairs and 14 in general and administrative
functions. None of our employees is a member of a labor union or is covered by
a collective bargaining agreement and we have never experienced a work
stoppage. We believe we have good relations with our employees.

ITEM 2. PROPERTIES

  Our principal executive offices and final assembly and testing facilities
are located in Bothell, Washington where we lease approximately 17,000 square
feet under a lease that expires in June 2004. We also maintain a facility used
primarily as an advanced development laboratory in approximately 4,700 square
feet of space in Oklahoma City, Oklahoma under a lease that expires in
December 2000. We also occupy approximately 10,600 square feet of office space
in Houston, Texas under a lease that expires in March 2004.

  We own substantially all of the equipment used in our facilities, except
equipment held under capitalized lease arrangements.

  We believe that our existing facilities are adequate to meet our immediate
needs and that suitable additional space will be available in the future on
commercially reasonable terms as needed.

ITEM 3. LEGAL PROCEEDINGS

  As of the date hereof, we are not party to any material pending legal
proceedings. No such proceedings were terminated during the fourth quarter of
the 1999 fiscal year.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

ITEM 5.  MARKET FOR REGISTRANT'S COMMON STOCK AND RELATED STOCKHOLDER MATTERS

Market for Our Common Stock

  Our common stock has been traded on the Nasdaq National Market under the
symbol "DCCA" since November 9, 1999, the date of our initial public offering.
Prior to that time, there was no public market for our common stock. The
following table sets forth, for the periods indicated, the high and low sales
prices for our common stock as reported by the Nasdaq National Market.

</TABLE>

  According to the our transfer agent, we had approximately 121 stockholders
of record as of December 31, 1999. Because many of such shares are held by
brokers and other institutions on behalf of stockholders, we are unable to
estimate the total number of stockholders represented by these record holders.

  We have never declared or paid any cash dividends on our capital stock. We
currently intend to retain any future earnings and therefore do not anticipate
paying any cash dividends in the foreseeable future.

Recent Sales of Unregistered Securities During 1999

  During 1999, we granted and issued options to purchase an aggregate of
765,962 shares of common stock with a weighted average exercise price of $8.54
to a number of our employees, directors and consultants pursuant to our 1994
stock option plan and our 1999 stock option plan.

  During 1999, we issued 19,760 an aggregate shares of common stock pursuant
to the exercise of stock options at a weighted average exercise price of $1.67
per share. All of these stock options were granted under our 1994 stock option
plan.

  In April 1999, we issued a warrant to purchase 12,500 shares of Series D
preferred stock with an exercise price of $4.00 per share to one holder in
partial consideration for financing an equipment lease to Data Critical. This
warrant became exercisable for 12,500 shares of common stock upon completion
of our initial public offering.

  In August 1999, we issued 7,500 shares of common stock to Michael Singer in
connection with his employment agreement.

  In October 1999, we issued to a commercial lender 105,000 shares of Series D
preferred stock at an exercise price of $5.00 per share upon exercise of a
purchase option for cancellation of indebtedness, which converted into 105,000
shares of common stock upon completion of our initial public offering.

  In December 1999, we issued 200,000 shares of common stock into escrow in
connection with our acquisition of substantially all of Physix's business,
assets and rights.

  The issuances of the above securities were deemed to be exempt from
registration under the Securities Act in reliance on Section 4(2) of
Regulation D, or other applicable exemption of the Securities Act as
transactions by an issuer not involving any public offering. In addition,
certain issuances described in Item 4 were deemed exempt from registration
under the Securities Act in reliance upon Rule 701 promulgated under the
Securities Act. The recipients of securities in each transaction represented
their intentions to acquire the securities for investment only and not with a
view to or for sale in connection with any distribution thereof and
appropriate

                                      17
<PAGE>

legends were affixed to the share certificates and warrants issued in the
transactions. All recipients had adequate access through their relationships
with Data Critical to information about Data Critical.

Report of Offering of Securities and Use of Proceeds Therefrom

  In November 1999, we completed a firm commitment underwritten initial public
offering of 4,025,000 shares of our common stock, including 525,000 shares
related to the underwriter's over-allotment option, at a price of $10.00 per
share. These shares were registered with the Securities and Exchange
Commission pursuant to a Registration Statement on Form S-1 (No. 333-78059),
which was declared effective on November 8, 1999. The public offering was
underwritten by a syndicate of underwriters led by Donaldson Lufkin &
Jenrette, U.S. Bancorp Piper Jaffray, Warburg Dillon Read LLC and DLJ Direct,
Inc. After deducting underwriting discounts and commissions of $2,817,500 and
expenses of approximately $932,500, we received net proceeds of approximately
$36,500,000 from the offering.

  As of March 1, 2000 we have invested the net proceeds from our initial
public offering in short and long-term investments in order to meet
anticipated cash needs for future working capital. We invested our available
cash principally in high-quality corporate issuers and in debt instruments of
the U.S. Government and its agencies. The use of proceeds from the offering
does not represent a material change in the use of proceeds described in the
Registration Statement. None of the net proceeds of the offering were paid
directly or indirectly to any director, officer, general partner of Data
Critical or their associates, persons owning 10 percent or more of any class
of equity securities of Data Critical, or an affiliate of Data Critical.

Overview

  Data Critical commenced operations in April 1993 to develop communications
solutions for individuals who have a need for notification of data that
requires an immediate response, also known as time-critical data. From 1993
through 1996, we primarily focused on expanding our research and development
efforts, refining our business plan, developing industry and strategic
relationships, building a management team and financing these activities.
Since inception, we have funded our operations primarily through debt and
equity financing from stockholders, cash receipts from sales and commercial
credit facilities.

  From inception through 1997, revenue was derived primarily from fees and
royalties paid under product engineering and development contracts, and to a
lesser extent from the sale of wireless communications systems developed for
both medical and non-medical applications. In late 1996, we focused our
development and marketing efforts on specific medical applications.
Accordingly, in 1997 we hired management and other key employees experienced
in sales, manufacturing and regulatory matters in the healthcare industry. As
a result of this new focus, our results of operations since the end of 1997
are not directly comparable to those of prior periods.

  We commercially launched our StatView system late in the third quarter of
1997. The StatView system was our primary source of revenue for 1998 and 1999,
and will continue to represent a substantial portion of our revenue for at
least the next 24 months. StatView system revenue includes the net sales price
of the system, installation and training services and software maintenance. In
future periods, we expect to receive additional revenue from the sale of newly
developed systems, like AlarmView, which we expect to launch for commercial
service in mid- 2000, and MobileView ECG Stat.

  We sell our systems through a national direct field sales force, alliances
with strategic partners and OEM arrangements. Our direct sales force regularly
works together with the sales teams of our strategic partners, in particular
Agilent Technologies, Inc., Siemens Medical Systems, Inc. and Protocol
Systems, Inc. We also sell our systems through OEM relationships with GE
Marquette Medical Systems, Inc. Due to revenue variability between direct and
OEM sales channels, future variations in mix of sales between these channels
could have a significant impact on revenue. We intend to increase the
proportion of our revenues generated by direct sales versus OEM sales.

  Data Critical receives revenues from direct sales of systems and is
generally recognized upon installation; revenue from OEM sales of systems is
generally recognized upon shipment; revenue generated from installation and
training fees is recognized upon completion of the related services; and
revenue from annual software maintenance fees is deferred and recognized over
the term of the applicable agreement. These revenue recognition principles are
consistent with Statement of Position 97-2, Software Revenue Recognition, as
amended by Statement of Position 98-4 and 98-9.

  Deferred revenue was $442,000 and $1.3 million at December 31, 1998 and
1999, respectively. This deferred revenue resulted primarily from the
recognition of systems shipped but not installed and software maintenance
fees. We recognize revenue that had been deferred upon shipment when the
system is installed and recognize revenue from software maintenance agreements
generally over one year terms. We expect that deferred revenue from software
maintenance agreements will represent a decreasing percentage of revenue in
future periods. We expect deferred revenue from these types of contracts to
vary as a percentage of revenue from quarter to quarter.

                                      19
<PAGE>

  Although a number of the components used in our systems are readily
available, some of these components are specifically manufactured for us. Due
to the significant investment in capital equipment that would be necessary to
manufacture these items in-house and the relatively low volumes we require, we
have chosen to utilize contract manufacturing firms to manufacture these
components. We generally purchase these components under contracts that
provide for fixed unit costs with incentives for process and design
improvements that result in future manufacturing cost savings.

Technology from the Physix Acquisition

  In December 1999, we acquired substantially all the assets of Physix, Inc.,
including Physix's developmental technologies and the hiring of approximately
fifteen employees. In the fourth quarter of 1999, we wrote off approximately
$1.8 million of in-process research and development acquired in connection
with the Physix acquisition.

  In connection with the acquisition, we conducted a valuation of the assets
acquired from Physix, including core technology, assembled workforce and in-
process research and development, utilizing the following major assumptions:
the revenue and margin contribution of each technology (in-process and future
yet-to-be defined); the percentage of carryover of technology from products
under development and products scheduled for development in the future; the
expected life of the technology; anticipated module development and module
introduction schedules; revenue forecasts, including expected aggregate growth
rates for the business as a whole and expected growth rates for the internet
content provider industry; forecasted operating expenses, including selling,
general and administrative expenses, as a percentage of revenues; and a rate
of return of 50% utilized to discount to present value the cash flows
associated with the in-process technologies.

  As of the acquisition date, Physix's significant ongoing research and
development projects included development of new wireless Internet product
technologies, including subscription-based eCommerce functionality. At the
time of the acquisition, these projects had an estimated aggregate completion
percentage of approximately 38%. Anticipated completion dates ranged from 6 to
12 months, at which times the Company expects to begin selling the developed
products.

  As a part of the valuation discussed above management estimates and
assumptions were made. While we believe that the assumptions were made in good
faith and were reasonable when made, such assumptions remain largely untested,
as the technology is yet in service and the other products have been in
service for a limited period of time. Accordingly, our assumptions may prove
to be inaccurate, and we may not realize the revenues, gross profit, growth
rates, expense levels or other variables set forth in such assumptions. See
"Factors Affecting Future Results."

  Significant technology development efforts are necessary before any one of
these products can successfully be completed and integrated into our wireless
communication products. The wireless web-based physician tool technology must
be developed in a manner compatible with the changing protocols and standards
that are emerging in the wireless industry, and will be greatly influenced by
emerging trends, protocols and standards.

  In January 2000, shortly after completion of the Physix acquisition, we
estimated the cost to complete initial development and integration of this
technology to be approximately $883,000. The magnitude of development efforts
needed to complete these initial developments is periodically reviewed by us.
See "Factors Affecting Future Results."

  The direct impact of the wireless web-based physician tool technology on
current and future results of operations, liquidity and capital resources is
not known. While we are positioning ourselves for, and are expending
considerable resources in anticipation of, internet/wireless medical
transaction revenues, we may not be able to timely or successfully develop
Web-based physician tool technology, which could harm our business.

  We anticipated receiving a number of synergies as a result of the Physix
acquisition, including gaining knowledgeable staff and acquiring products and
services at least partially developed, which together may reduce

                                      20
<PAGE>

time-to-market for subsequent wireless-internet product development and
implementation. We anticipate that any successful wireless-internet products
or services will, when generating material revenues, yield economies of scale
in company-wide selling, general and administrative expenses. However, there
can be no assurance that we will realize any of such benefits. See "Factors
Affecting Future Results."

Recent Developments

  On March 13, 2000, we entered into an agreement to merge Elixis, Inc. with a
wholly owned subsidiary of Data Critical. Elixis shareholders will receive
shares of Data Critical common stock in exchange for their shares of Elixis
stock. The combined company will be known initially as datacritical.com inc.
This transaction will be accounted for as a purchase and will become effective
upon approval by the shareholders of Elixis and the satisfaction of other
conditions.

 1999 Compared to 1998

  Revenue. Revenue increased $5.4 million or 130.6% to $9.5 million in 1999
compared to $4.1 million for the comparable period in 1998. While our average
selling price remained relatively constant, the increase in revenue was
primarily due to increased unit sales volumes of StatView systems from our OEM
arrangement with GE Marquette Medical Systems, Inc. combined with sales
generated by our direct sales force and co-marketing activities with our
strategic partners.

  Gross margin. Gross margin consists of revenue less cost of revenue. Cost of
revenue associated with our systems consists of purchased components, cost of
contract manufacturing, labor for assembly and installation, and overhead.
Gross margin increased $3.6 million or 158.1%, in 1999 from 1998. Gross margin
as a percentage of revenue increased to 62.1% in 1999 from 55.5% in 1998.
Gross margin increased in absolute dollars primarily as a result of increased
revenue generated by additional sales of StatView systems. The improvement in
the gross margin percentage resulted from cost reductions on components for
our StatView receivers purchased during 1999 and from decreased costs in 1999
on a per system basis due to inefficiencies related to production start-up
costs, changing contract manufacturers and very low production volumes that
occurred in 1998.

  Research and development. Research and development expenses consist
primarily of personnel and related costs, travel and contract engineering
services. Research and development expenses increased $0.3 million or 13.9% to
$2.5 million in 1999 compared to $2.2 million in 1998. Research and
development costs represented 26.2% of total revenues for 1999 and 53.0% in
1998. The decrease in research and development expenses as a percentage of
total revenues primarily reflects the increase in revenues relative to the
increase in research and development staff to develop and enhance our
products. We believe that research and development costs will continue to
increase as it expands our product offerings.

  Sales and marketing. Sales and marketing expenses consist primarily of
personnel and related expenses, sales commissions, trade show and advertising
expenses, telecommunications costs and consulting fees. Sales and marketing
expenses increased $0.8 million or 23.8% to $4.3 million compared to $3.5
million for the comparable period in 1998. This increase was primarily due to
additional sales personnel increasing associated expenses, such as sales
commissions, trade shows and public relations. Sales and marketing expenses
represented 84.9% of total revenues in 1998 and 45.6% in 1999. The decrease in
marketing and sales expenses as a percentage of total revenues from 1998 to
1999 reflects the more rapid growth in revenues compared to the growth of
marketing and sales expenses due to early investment in marketing activities
to create product awareness. We believe that we will need to continue to
increase our sales and marketing efforts to expand market penetration and
increase acceptance of our products and services.

  General and administrative. General and administrative expenses consist
primarily of personnel and related expenses, travel, communication and
professional fees. General and administrative expenses increased $1.6 million
or 62.7% to $4.2 million in 1999 compared to $2.6 million in 1998. General and
administrative expenses represented approximately 43.7% of total revenues in
1999 and 62.0% in 1998. This increase was primarily due to increases in salary
and bonus for existing personnel and the addition of regulatory and office
support staff to support the growth of our business. We believe that general
and administrative expenses will continue to increase as we expand
administrative staff and incur expenses associated with being a public
company, including annual and other public reporting costs, director and
officer liability insurance, investor relations programs and professional
services fees.

  Operating expenses. Operating expenses increased $4.5 million or 54.5% to
$12.8 million in 1999 compared to $8.3 million in 1998 primarily due to an
increase in the number of employees performing sales and marketing, general
and administrative, and research and development functions. Operating expenses
as a percentage of revenue decreased to 134.0% in the twelve months ended
December 31, 1999 from 199.9% in the comparable period of 1998.

  Other income (expense), net. Other income (expense), net, decreased $117,000
or 77.0% to a net other income of $35,000 in the twelve months ended December
31, 1999 from a net other income of $152,000 in the

                                      22
<PAGE>

comparable period of 1998. This resulted primarily from an increase in
borrowings during 1999. Data Critical expects other income to increase
substantially in 2000 primarily due to the increase in cash and cash
equivalents
and short-term investments. However, the amount of the increase will be
effected by changes in interest rates, and the rate at which we use the funds
to support our growth.

 1998 Compared to 1997.

  Revenue. Revenue increased to $3.7 million in 1998 from $471,000 in 1997, an
increase of 778.3%. This increase resulted primarily from increased sales of
our StatView system, which was launched in the second half of 1997. This
increase in StatView sales was primarily due to: the hiring and training of a
direct sales force in late 1997; increased StatView system sales to GE
Marquette Medical Systems, Inc.; and direct sales of StatView systems for
Agilent Technologies monitoring devices beginning in July 1998.

  Gross margin. Gross margin increased to $2.3 million in 1998 from $123,000
in 1997. Gross margin as a percentage of revenue increased to 55.5% in 1998
from 26.1% in 1997. Gross margin increased in absolute dollars primarily as a
result of increased revenue generated by additional sales of StatView systems.
The margin percentage increase resulted primarily from our write off of
$197,000 in inventory related to a discontinued product, which hurt our 1997
gross margin. In addition, 1998 gross margins were reduced by inefficiencies
related to production start-up costs, changing contract manufacturers and
minimal production volumes.

  Research and development. Research and development expenses increased to
$2.2 million in 1998 from $1.7 million in 1997, an increase of 28.9%. This
increase was primarily due to incurring a full year of salary and benefits for
a Director of Engineering hired in May 1997, additional personnel hired during
1998, an increase in travel expenditures to support an increasing number of
alliances with strategic partners and an increase in contract engineering
services.

  Sales and marketing. Sales and marketing expenses increased to $3.5 million
in 1998 from $1.2 million in 1997, an increase of 192.7%. This increase was
primarily due to a full year of costs associated with our direct sales force,
of which hiring began in August 1997, and includes an increase in salaries,
benefits and related costs and increased sales commissions.

  General and administrative. General and administrative expenses increased to
$2.6 million in 1998 from $1.3 million in 1997, an increase of 102.2%. This
increase was primarily due to incurring a full year of salary, benefits and
related costs for the addition, from June through November 1997, of several
senior management positions, and their related support staff.

  Operating expenses. Operating expenses increased to $8.3 million in 1998
from $4.2 million in 1997, an increase of 98.3%, primarily due to an increase
in the number of employees performing sales and marketing, general and
administrative, and research and development functions.

  Other income (expense), net. Other income (expense), net, increased to a net
other income of $152,000 in 1998 from a net other income of $45,000 in 1997.
The increase in 1998 resulted from an increase in interest income from the
investment of net proceeds received from our Series D preferred stock offering
completed in the first half of 1998. This increase was partially offset by an
increase in interest expense from bridge loans outstanding from November 1997
until March 1998, increases in term loans used for equipment purchases and the
use of our revolving line of credit.

Provision for Income Taxes

  Due to our history of net operating losses, we currently pay no federal or
state income tax. As of December 31, 1999, we had approximately $20.0 million
of net operating loss carry forwards for federal income tax purposes, which
expire beginning in 2008. Federal and state law restrictions, including those
related to ownership changes in our voting stock, as defined in the Internal
Revenue Code, will limit our ability to use these net operating losses to
offset future income tax obligations in any one year.

                                      23

Liquidity and Capital Resources

  As of December 31, 1999, we had $34.0 million of cash and cash equivalents
up from $3.1 million at December 31, 1998. As of December 31, 1999 our
principal commitments consisted of obligations outstanding under operating
leases and commercial bank loans. Since inception, we have satisfied our
liquidity needs primarily from the net proceeds of approximately $54.3 million
generated through private and public sales of common and preferred stock and,
to a lesser extent, from bank borrowings and advance deposits received from
customers on open orders.

  Net cash used in operating activities was $4.3 million in the twelve months
ended December 31, 1999, $5.3 million in 1998 and $3.7 million in 1997. Net
cash used in operating activities for each of these periods primarily
consisted of net losses as well as increases in accounts receivable, prepaid
expenses and inventories partially offset by increases in accounts payable and
other current liabilities, net deferred revenue and depreciation and
amortization. Working capital increased to $33.1 million at December 31, 1999
from $2.3 million at December 31, 1998, primarily due to net proceeds of $36.5
million received from the sale of our common stock offset by net losses from
operating activities. Working capital increased to $2.3 million at December
31, 1998 from $717,000 at December 31, 1997, primarily due to the issuance of
$539,000 of convertible notes and net proceeds of $7.0 million received from
the private sale of our Series D preferred stock.

  Investing activities used net cash of $2.2 million in the twelve months
ended December 31, 1999 and $394,000 in 1998 and provided net cash of $1.6
million in 1997. Net cash used in investing activities in the twelve months
ended December 31, 1999 consisted of $1.5 million used for the acquisition of
Physix, Inc. and $584,000 for purchases of equipment and systems while 1998
primarily consisted of purchases of equipment and systems, including computer
equipment. Net cash provided by investing activities in 1997 primarily
consisted of sales of marketable securities, which were partially offset by
purchases of computer and office equipment.

  Net cash provided by financing activities was $37.5 million for the twelve
months ended December 31, 1999, $7.9 million in 1998 and $2.3 million in 1997.
Net cash provided by financing activities during 1999 consisted of proceeds
from the net proceeds of $36.5 million from the sale of our common stock, net
proceeds of $2.2 million issuance of notes payable and line of credit
partially offset by $1.2 million in notes payable and line of credit
repayments. Net cash provided by financing activities during 1998 primarily
due to the issuance of $539,000 of convertible notes, net proceeds of $7.0
million from the issuance of preferred stock, and proceeds from the issuance
of $450,000 of debt obligations. Net cash provided by financing activities in
1997 primarily consisted of net proceeds of $650,000 from the issuance of
common stock on the exercise of warrants and the issuance of bridge notes
payable of $1.6 million.

  From January 1, 1997 through December 31, 1999, we have invested a total of
approximately $1.2 million in fixed assets, consisting primarily of computer
equipment, related software and office furniture. We expect to spend an
additional $500,000 over the next 12 months for additional fixed assets,
principally leasehold improvements and furnishings for our new offices,
computer systems, demonstration equipment and additional production test
equipment. Approximately $200,000 of this amount will be invested in an
integrated management information system, which comprises all sales,
accounting, inventory and manufacturing control systems, the implementation of
which began in April 1999 and is expected to conclude in the first quarter of
2000. We had no material commitments for capital expenditures at December 31,
1999.

  We have a working capital line of credit that allows us to borrow up to 60%
to 75% of eligible accounts receivable to a maximum of $1.5 million. The line
is collateralized by substantially all of our assets and incurs interest at
the bank's prime rate plus 0.75%. This line of credit expires in April 2000
and requires us to comply with various financial covenants including tangible
net worth, liquidity ratios and maximum quarterly operating losses. As of
December 31, 1999, no borrowings were outstanding and $340,000 in letters of
credit issued to provide collateral for our new facility lease were drawn
under this line of credit.

  In April 1999, we established a subordinated debt facility totaling $1.5
million that was required to be drawn upon by October 1999. Loans made under
this facility are secured by substantially all of our assets, subordinated

                                      24
<PAGE>

to the commercial bank loans referenced above. Advances under the subordinated
debt agreement are limited to $500,000 or more per advance and are payable at
interest only for the first twelve months at an 11% rate and in equal monthly
principal and interest payments for the following 24 months. As of December
31, 1999, $987,000 million was outstanding under this debt facility. In
connection with this debt facility, we also granted the lender an option to
purchase up to 105,000 shares of our Series D preferred stock at a purchase
price of $5.00 per share. The lender exercised this option in full on October
25, 1999. In January 2000 this obligation was paid in full.

  The same lender has also provided a lease line of credit for up to $1.0
million, comprised of $800,000 to finance equipment and $200,000 to finance
equipment, leasehold improvements and software. Advances made under the lease
line are payable over 36 equal monthly installments. As of December 31, 1999,
$161,000 was outstanding under this lease line. As part of this lease line,
the lender received a warrant to purchase 12,500 shares of Series D preferred
stock at an exercise price of $4.00 per share. This warrant, which became
exercisable for 12,500 shares of our common stock upon completion of our
initial public offering, expires upon the earlier of April 27, 2006 or five
years after our initial public offering.

  Although it is difficult for us to predict future liquidity requirements
with certainty, we believe that the net proceeds from our initial public
offering, together with our existing liquidity sources and anticipated funds
from operations, will satisfy our cash requirements for at least the next 12
months. Thereafter, we may require additional funds to support our working
capital requirements or for other purposes and may seek additional funds
through public or private equity or debt financings or from other sources.
There can be no assurance that additional financing will be available to us or
that, if available, the financing will be available on terms favorable to us
and our stockholders.

Year 2000 Compliance

  In 1999 we began working to address the possible effects of the potential
inability of computer programs to adequately process date information after
December 31, 1999 (Year 2000). We conducted a review of our products,
information technology and facilities computer systems to identify all
software that could be affected by the Year 2000 issue and developed and
executed plans to address it. These actions were completed in the fourth
quarter of 1999. With the passing of January 1, 2000, we report that no
significant Year 2000 problems arose. These costs were expensed as incurred.
No further significant expenditures related to the Year 2000 issue are
expected.

Recent Accounting Pronouncements

  In March 1998, the Accounting Standards Board issued Statement of Position
98-1, Accounting for the Costs of Computer Software Developed or Obtained for
Internal Use, which is effective for fiscal years beginning after December 15,
1998. The SOP will require the capitalization of certain costs incurred after
the date of adoption in connection with developing or obtaining software for
internal use. We currently expense such costs as incurred. Management has not
yet determined what the effect of SOP 98-1 will be on our consolidated
financial position or results of operations.

  In April 1998, the Accounting Standards Board issued Statement of Position
98-5, Reporting on the Costs of Start-Up Activities. SOP 98-5, which is
effective for fiscal years beginning after December 15, 1998, provides
guidance on the financial reporting of start-up costs and organization costs.
It requires costs of start-up activities and organization costs to be expensed
as incurred. As we have expensed these costs historically, the adoption of
this standard is not expected to have a significant impact on our results of
operations, financial position or cash flows.

  In June 1998, the Financial Accounting Standards Board, or FASB, issued
Statement of Financial Accounting Standards, or SFAS, No. 133, Accounting for
Derivative Instruments and Hedging Activities. SFAS No. 133 establishes
methods of accounting for derivative financial instruments and hedging
activities related to those instruments as well as other hedging activities.
In June 1999, the FASB issued Statement

                                      25
<PAGE>

No. 137, Accounting for Derivative Instruments and Hedging Activities--
Deferral of the Effective Date of FASB Statement No. 133. Statement No. 137
defers the effective date of Statement No. 133 for one year. Statement No. 133
is now effective for all fiscal quarters of all fiscal years beginning after
June 15, 2000. Because we currently hold no derivative financial instruments
and do not currently engage in hedging activities, adoption of SFAS No. 133 is
expected to have no material impact on our financial condition or results of
operations.

Factors Affecting Future Results

  You should carefully consider the risks described below, together with all
of the other information included in this annual report on Form 10-K and the
information incorporated by reference herein. If we do not effectively address
the risks we face, our business will suffer and we may never achieve or
sustain profitability. See "Selected Financial Data" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

  This annual report on Form 10-K also contains forward-looking statements
that involve risks and uncertainties. Our actual results could differ
materially from those anticipated in the forward looking statements as a
result of factors that are described below and elsewhere in this annual report
on Form 10-K.

 If our potential customers in the healthcare industry are not willing to
 adopt our communications systems, our growth and revenue will be limited.

  Our business model depends on our ability both to sell our systems to
hospitals, physicians and other healthcare providers and to generate usage by
a large number of these customers. Healthcare industry participants may not
accept the transmission of critical data through networked medical monitoring
equipment and the internet as readily as we anticipate. We believe that the
complex nature of time-critical data transmission has and may continue to
hinder the development and acceptance of communications solutions similar to
ours by the healthcare industry. Conversion from traditional methods of
communication may not occur as rapidly as we expect. Even if acceptance or
conversion does occur, healthcare industry participants may use alternative
products and services offered by others.

  We believe that we must gain significant market share in the healthcare
industry with our systems before competitors introduce alternative products or
systems with features and benefits similar to ours. Our business model is
based on our belief that the value and market appeal of our solution will grow
as the number of participants and scope of data transmitted increase. We may
not achieve the critical mass of users that is necessary to become successful.
Any significant shortfall in the number of users of our systems would reduce
our growth and revenue.

  Failure to achieve broad acceptance of our products and services by
physicians and other healthcare stakeholders would also severely limit our
ability to implement our internet-based business model. Achieving market
acceptance for our products and services will require substantial marketing
efforts and the expenditure of significant financial and other resources to
create awareness and demand by physicians and healthcare consumers. Use of our
products and services requires physicians to integrate our products and
services into their office work flow and to adopt different behavior patterns
and new methods of conducting business and exchanging information. Physicians
may not choose to use our products and services.

 We cannot assure you we will achieve profitability.

  We have not achieved profitability and, although our revenue has grown in
recent quarters, we cannot be certain that we will realize sufficient revenue
to achieve profitability. We have incurred net losses of $8.6 million from
inception through December 31, 1997, $5.8 million in 1998 and $6.8 in 1999. As
of December 31, 1999, we had an accumulated deficit of $25.0 million. We
expect to continue to incur net losses for at least the next nine to twelve
months, although this timeframe could be longer. We anticipate continuing to
incur significant sales and marketing, product development and general and
administrative expenses and, as a result, we will need to generate
significantly higher revenue to achieve and sustain profitability.

                                      26
<PAGE>

 Our success is highly dependent on sales, marketing and development alliances
 with a small number of strategic partners; if these strategic partners
 terminate their relationships with us, our competitive position and revenue
 would suffer.

  We depend on our alliances with strategic partners to generate increased
acceptance of our systems. To date, we have established only a limited number
of strategic alliances, and these alliances are in the early stages of
development. We currently maintain co-marketing partnerships with Agilent
Technologies, Inc., (formerly a division of Hewlett-Packard Company), Protocol
Systems, Inc., Siemens Medical Systems, Inc., Medical Data Electronics, Inc.,
Zymed, Inc. and Datascope Corp., whose larger sales forces sell our systems on
a commission basis. In addition, we have original equipment manufacturing and
distribution partnerships with GE Marquette Medical Systems, Inc. and Nellcor
Puritan Bennett, a subsidiary of Mallinckrodt Inc. A substantial portion of
our revenue during 1998 and 1999 was derived from the sale of systems marketed
or distributed through Agilent Technologies, Inc. and GE Marquette Medical
Systems, Inc. Either of these companies may decide to discontinue their
distribution, marketing or original equipment manufacturing relationships with
us, including as a result of proposed corporate reorganizations. Our
agreements with these companies may be cancelled on short-term notice. If
either company limits or discontinues marketing or selling our systems, our
revenue would fall short of our expectations.

  If any of these strategic alliances are terminated or if we fail to
establish additional alliances, we would not be able to execute our business
model and the growth of our business would be hurt significantly. We may not
experience increased use of our systems even if we establish and maintain
these strategic alliances.

 We expect to commit substantial resources to marketing, development and
 operations expenses; if we are unable to generate increasing revenue in
 excess of these commitments, we will not be able to achieve profitability.

  We anticipate that our expenses will increase substantially for at least the
next 12 months as we increase our sales and marketing activities, further
develop our technology, broaden our system offerings, expand our distribution
channels and potentially pursue acquisitions. If we fail to significantly
increase our revenue as we implement our system development and distribution
strategies, we will not be able to achieve profitability. In addition, we may
not experience any revenue growth in the future, and our revenue could
decrease. Our efforts to expand our sales and marketing activities, system
offerings, and direct and indirect distribution channels and our efforts to
pursue strategic alliances may not succeed or may prove more expensive than we
currently anticipate. As a result, we cannot predict our future profitability
with any degree of certainty.

 Our quarterly financial statements are likely to fluctuate and are not a good
 indication of our future performance because our revenue is heavily dependent
 on the timing of customer installations of our systems and our sales mix by
 distribution channel.

  Our revenue in any quarter depends significantly on the timing of systems
shipped and installations completed. Any unexpected delays or cancellations of
shipments or installations at the end of a quarter could substantially reduce
revenue in that quarter, hurt our revenue and impair our business in future
periods. Because we do not know when, or if, our potential customers will
place orders, finalize contracts and permit installation, we cannot accurately
predict revenue and profitability for future quarters. In addition, the mix of
sales between distribution channels will have a significant impact on
quarterly and annual revenue and profitability because we receive higher
revenue and gross margin on direct sales, including those made through our
alliances with strategic partners, than we do on original equipment
manufacturer sales.

  In addition, because Data Critical only began operations in March 1996, and
because the market for our hospital and physician based systems is new and
evolving, it is very difficult to predict future financial results. We plan to
significantly increase our sales and marketing, research and development and
general and administrative expenses in 2000. Our expenses are partially based
on our expectations regarding future revenues,

                                      27
<PAGE>

and are largely fixed in nature, particularly in the short term. As a result,
if our revenues in a period do not meet our expectations, our financial
results will likely suffer.

  We believe that quarter-to-quarter comparisons of our financial statements
are not a good indication of our future performance. It is likely that in
future quarters our revenue and earnings may be below the expectations of
securities analysts and investors and, as a result, the price of our common
stock may fall. Our revenue and earnings have varied in the past, and we
expect that they will continue to vary significantly from quarter to quarter.

 We are dependent on sales of StatView for a large portion of our revenue;
 failure to maintain and continue to grow sales of StatView systems would
 likely reduce our revenue.

  During 1998 and 1999, substantially all of our revenue was derived from
sales of our StatView system. Although we expect that our MobileView ECG Stat
and AlarmView systems will account for an increasing portion of revenue in the
future, it is likely that sales of our StatView system will continue to
represent a substantial portion of our revenue for at least the next 24
months. Any factors that reduce the pricing of, demand for or market
acceptance of our StatView system, including competition or technological
change, could significantly reduce our revenue.

 Our internet-based business model may not be successfully implemented and is
 difficult to evaluate because it is new and unproven.

  We have only recently implemented our internet-based business model, and we
do not have an operating history with this model upon which you can evaluate
our prospects. In attempting to implement our internet-based business model,
we are significantly changing our business operations, sales and
implementation practices, customer service and support operations and
management focus. Developing and marketing our internet systems to the
physician and to the at-home consumer healthcare industry will also be costly
and time-consuming. Our internet systems require that hospitals, physicians
and consumers manage information in a new and different way. In order to
maximize the benefits of our internet systems, at-home healthcare consumers
must be willing to allow sensitive personal information to be stored on our
internet databases. We have not yet fully determined how to commercialize our
internet systems, and we cannot assure you that hospitals, physicians and the
at-home consumer healthcare industry will accept these systems.

  We are also facing new risks and challenges, including a lack of meaningful
historical financial data upon which to plan future budgets, the need to
develop strategic relationships and other risks described below. For each of
the last three fiscal years, all of our revenue was generated from the sale of
hospital communication systems and services and no revenue was derived from
our internet-based products and services. Our operating history is not
indicative of our future performance under our internet-based business model,
and you should not rely upon our past performance to predict our future
performance. If we fail to develop or market our internet systems, or if
hospitals, physicians and the at-home consumer healthcare industry fails to
accept our internet systems, the future growth of our business would likely
suffer.

 We have recently made acquisitions and may make additional acquisitions in
 the future and we may not successfully assimilate the acquired operations or
 products.

  We have recently acquired the businesses of Physix and Elixis and may make
additional acquisitions in the future, although there can be no assurance that
suitable companies, products or technologies will be available for
acquisition. Acquisitions entail numerous risks, including assimilation of the
operations and products, retention of key employees, diversion of our
management's attention, and uncertainties in our ability to maintain key
business relationships the acquired entities have established. In addition, if
we undertake future acquisitions, we may issue dilutive securities, assume or
incur additional debt obligations, incur large one-time expenses, and acquire
intangible assets that would result in significant future expense. Also,
recently the Financial Accounting Standards Board ("FASB") voted to eliminate
pooling of interests accounting for acquisitions and voted to

                                      28
<PAGE>

eliminate the immediate write-off of acquired in-process research and
development. The effect of these changes would be to increase the portion of
the purchase price for any future acquisitions that must be charged to our
cost of revenues and operating expenses in the periods following any such
acquisitions. Any of these events could have a material adverse effect upon
our business, operating results and financial condition.

 If we are unable to keep pace with technological innovation in our industry,
 our ability to continue the rapid growth of our business will be impaired.

  The industries in which we operate are characterized by rapid technological
change, changes in end user preferences and the emergence of new industry
standards and practices that could render our existing systems and proprietary
technology obsolete. Our success depends, in part, on our ability to continue
to enhance our existing systems and to develop new systems that meet the
changing needs of our customers. If we are unable to develop and introduce in
a timely manner new and enhanced systems that incorporate the latest
developments in medical equipment and wireless communications technologies,
our sales will be harmed. The pace of change in information-dependent markets,
such as the healthcare industry, is rapid and there are frequent new product
introductions and evolving industry standards. We may be unsuccessful in
responding to technological developments and changing customer needs. In
addition, our systems may become obsolete due to the adoption of new
technologies or standards by our customers or competitors. We have experienced
development delays in the past and may experience similar or more significant
delays in the future. Difficulties in system development could delay or
prevent the successful introduction or marketing of new or enhanced systems.

 Our infrastructure may be unable to keep pace with, and as a result, hinder
 our growth.

  We have rapidly and significantly expanded our operations and expect this
expansion to continue. Our revenue grew from $471,000 in 1997 to $4.1 million
in 1998 to $9.5 million in 1999. During 1999, we moved our Redmond, Washington
headquarters and assembly plant into new facilities in Bothell, Washington. In
addition, we expect to hire a significant number of new employees to implement
and expand our operational, sales, marketing and customer support activities.
In the fourth quarter of 1999, we completed the implementation an integrated
management information system, which includes all sales, accounting, inventory
and manufacturing control functions. We expect to face increasing daily
operational challenges as our business continues to grow, and we may fail to
properly manage our growth, and as a result, could face reduced revenue and
earnings.

 We may not be able to effectively compete in the market for hospital-based
 wireless data communications and may be forced to reduce prices, leading to
 decreased revenue.

  Many companies selling products using traditional methods of patient
monitoring, including direct patient oversight and monitoring through wired
systems and voice communications, are well positioned to compete with us in
our hospital-based systems business. If these companies are drawn into our
market, we may be unable to effectively compete. To maintain and improve our
competitive position, we must continue to:

  .  successfully demonstrate the benefits of our systems to current and
     potential customers;

  .  market to hospitals and healthcare professionals;

  .  maintain stable and constructive alliances with key manufacturers of
     complementary medical equipment; and

  .  develop new and improved technologies.

  Many of our potential competitors have longer operating histories,
significantly greater financial, technical, marketing and other resources,
better name recognition and a larger installed base of customers. Many of our
potential competitors may also have well-established relationships with our
existing and prospective customers. Due to these and other advantages, our
potential competitors may develop products comparable or superior to our
systems or adapt more quickly to new technologies, evolving industry
standards, new product introductions or changing customer requirements. In
addition, there is the possibility that one or more of our strategic partners

                                      29
<PAGE>

or other medical equipment manufacturers may decide to develop products that
directly compete with our systems. We also expect that competition will
increase as a result of medical equipment, wireless and software industry
consolidation. Increased competition is likely to result in price reductions,
reduced gross margins and loss of market share, any one of which could cause
our sales to decline.

 If our customers experience system defects, delays in transmission or
 security breaches with our systems, we could face damage to our business
 reputation and potential legal liability.

  Our customer satisfaction and our reputation could be harmed if we or our
customers experience any system defects, delays, failures or loss of data. We
depend on the efficient operation of wireless networks and the internet for
communication. A major catastrophic event or other event beyond our control,
including a major security breach in the transmission of data on our systems
or a well-publicized compromise of internet security, could cause loss of
revenue and market share, damage our reputation and result in liability to us.
In addition, our systems may be vulnerable to computer viruses, programming
errors, attacks by third parties or similar disruptive problems. Furthermore,
patient care could suffer and we could be liable if our systems fail to
deliver correct information in a timely manner. Our contracts attempt to limit
our liability arising from our errors; however, these provisions may not be
enforceable and may not protect us from future liability. While we have
general liability and product liability insurance, including coverage for
errors and omissions, we may not be able to maintain this insurance on
reasonable terms in the future. In addition, our insurance may not be
sufficient to cover large claims, and our insurer could disclaim coverage on
claims. If we are liable for an uninsured or underinsured claim, or if our
premiums increase significantly, our growth and earnings could be harmed.

 Our failure to successfully enhance current products and services could
 adversely affect the implementation of our internet-based business model.

  Failure to enhance our product and service offerings to add functionality in
areas such as interfacing with the products of our strategic partners could
make it more difficult for us to implement our internet-based business model.
Developing, integrating, enhancing and customizing our products and services
will be expensive and time consuming.

 Intense competition in the internet healthcare industry may hinder sales of
 our internet systems.

  The internet healthcare industry is intensely competitive and subject to
fragmentation, high growth and rapid technological change. We may face
significant competition from traditional healthcare information system vendors
and internet healthcare companies as they expand their product offerings. Many
of these companies have significantly greater financial resources, well-
established brand names and large installed customer bases. We may be unable
to compete unsuccessfully against these organizations.

 Failure to continue to expand and adapt our network infrastructure to
 accommodate increased use by our customers could make it difficult to
 successfully implement our internet-based business model.

  To successfully implement our internet-based business model, we must
continue to expand and adapt our network infrastructure to accommodate
additional users, increased transaction volumes and changing customer
requirements. Our infrastructure may not accommodate increased use while
maintaining acceptable overall performance. To date, we have processed a
limited number and variety of internet-based transactions. In addition, our
internet products and services have only been used by a limited number of
physicians and healthcare consumers. An unexpectedly large increase in the
volume or pace of traffic on our web site, the number of physicians using our
internet products or our other internet-based products and services, or orders
placed by customers may require us to expand and further upgrade our
technology. This expansion and adaptation would be expensive and will divert
our attention from other activities.

                                      30

 Our sales are dependent on third party single-source and limited-source
 suppliers; this dependency reduces our control over the manufacturing process
 of our systems, which could reduce our revenue and earnings.

  We use third party manufacturers to purchase necessary components and to
manufacture and test key parts of our systems, including the StatView receiver
and the AlarmView transmitter. Certain components, including the bitmap
display, are presently only available from a single source. Other parts and
components that we rely on are available from limited sources. Our reliance
upon these single or limited-source suppliers and third party manufacturers
involves risks and uncertainties, including the possibility of a shortage or
discontinuation of key components and reduced control over delivery schedules,
manufacturing capability, quality and cost. Any reduced availability of these
components or key parts, when needed, could delay the delivery of complete
systems, result in the delayed payment or cancellation of orders by our
customers and cause our revenue and earnings to decline.

 If we lose members of our senior management team, we may not be able to
 successfully manage our business or achieve our objectives and our
 competitive position and growth would suffer.

  Our success will depend significantly on the continued contributions of our
senior management team, many of whom would be difficult to replace. In
particular, we believe that our future success depends on Dr. David Albert,
Chief Scientist and Chairman of the Board; Jeffrey Brown, President and Chief
Executive Officer; Michael Singer, Chief Financial Officer. We maintain key
person life insurance on the life of Jeffrey Brown in the amount of $1.0
million.

 We may not be able to hire and retain the personnel necessary to support our
 expanding business, which could threaten our future growth.

  We believe our future success will depend in large part on our ability to
identify, attract and retain engineering, sales and marketing, and customer
service and support personnel. Because of the complexity of our
systems and technologies, we are substantially dependent upon the continued
service of our existing engineering personnel as well as future hiring of
engineers with high levels of experience in designing complex systems like
ours. In addition, although we have recently expanded our direct sales force
and plan to hire additional sales personnel, we need to substantially expand
our sales operations and marketing efforts, both domestically and
internationally, in order to increase market awareness and sales of our
systems. Our systems require a sophisticated sales effort targeted at several
people within the information technology departments of our prospective
customers.

  Furthermore, we currently have a small customer service and support
organization and will need to increase our staff to support new customers and
the expanding needs of existing customers. Hiring personnel is highly
competitive in our industry due to the limited number of people available with
the necessary technical skills. We face intense competition for this
personnel, and we cannot assure you that we will be able to hire and retain
them in sufficient numbers.

 Federal and state legislation and regulation affecting the healthcare
 industry could severely restrict our ability to operate our business.

  We are subject to federal and state legislation and regulation affecting the
healthcare industry. Existing and new laws and regulations applicable to the
healthcare industry could have a material adverse effect on our ability to
operate our business. The federal and state governments extensively regulate
the confidentiality and release of patient records. Additional legislation
governing the distribution of medical records and health information has been
proposed at both the federal and state level. It may be expensive to implement
security or other measures designed to comply with any new legislation.
Moreover, we may be restricted or prevented from delivering patient records or
health information electronically.

                                      31
<PAGE>

  Other legislation currently being considered at the federal level could also
negatively affect our business. For example, the Health Insurance Portability
and Accountability Act of 1996 mandates the use of standard transactions and
identifiers, prescribed security measures and other provisions within two
years after the adoption of final regulations by the Department of Health and
Human Services. Because we intend to market some of our services as meeting
these regulatory requirements, our success will also depend on other
healthcare participants complying with these regulations.

  A federal law commonly known as the Medicare/Medicaid anti-kickback law, and
several similar state laws, prohibit payments that are intended to induce
physicians or others to acquire, arrange for or recommend the acquisition of
healthcare products or services. Another federal law, commonly known as the
Stark law, prohibits physicians from referring Medicare and Medicaid patients
for designated health services to entities with which they have a financial
relationship, unless that relationship qualifies for an explicit exception to
the referral ban. The application and interpretation of these laws are complex
and difficult to predict and could constrain our financial and marketing
relationships or our ability to obtain pharmaceutical company sponsorship for
our products.

 State restrictions on the practice of medicine may negatively affect our
 activities.

  Any finding in a state that we are not in compliance with its laws could
require us to restructure our services, which could adversely affect our
revenues or share price. The laws in some states prohibit some business
entities, such as Data Critical, from practicing medicine. This is commonly
referred to as the prohibition against the "corporate practice of medicine."
These laws generally prohibit us from employing physicians to practice
medicine or from directly furnishing medical care to patients. Each state
requires licensure for the practice of medicine within that state, and some
states consider the receipt of an electronic transmission of selected
healthcare information in that state to be the practice of medicine. Some
states have similar prohibitions on corporate practice and licensure
requirements for other regulated health care professions (for example, nurse
practitioners or pharmacists). These laws restrict our activities and the
extent to which we can provide medical advice to consumers, physicians and
others. If challenged, our activities may not be found to be in compliance
with these laws. We are also expanding internationally, and may face similar
restrictions on our activities outside the United States.

 The internet is subject to many legal uncertainties and potential government
 regulations that may decrease demand for our systems, increase our cost of
 doing business or otherwise have a material adverse effect on our financial
 results or prospects.

  Our internet business model is subject to evolving government regulation of
the internet. Existing as well as new laws and regulations could severely
restrict our ability to operate our business. Any new law or regulation
pertaining to the internet, or the application or interpretation of existing
laws, could decrease demand for our internet systems, increase our cost of
doing business or otherwise have a material adverse effect on our financial
results and prospects.

  Laws and regulations may be adopted in the future that address internet-
related issues, including online content, user privacy, pricing and quality of
products and services. For example, although it was held unconstitutional, in
part, the Communications Decency Act of 1996 prohibited the transmission over
the internet of various types of information and content. In addition, several
telecommunications carriers are seeking to have telecommunications over the
internet regulated by the Federal Communications Commission in the same manner
as other telecommunications services. Because the growing popularity and use
of the internet has burdened the existing telecommunications infrastructure in
many areas, local exchange carriers have petitioned the FCC to regulate
internet service providers in a manner similar to long distance telephone
carriers and to impose access fees on the internet service providers.

  The United States or foreign nations may adopt legislation aimed at
protecting internet users' privacy. This legislation could increase our cost
of doing business and negatively affect our financial results. For example,
the Federal Trade Commission will start enforcing requirements under the
Children's Online Privacy Protection Act

                                      32
<PAGE>

in April 2000. The act applies to the online collection of personal
information from children under 13, and imposes significant compliance burdens
and potential penalties on operators of web sites that collect covered
information. Moreover, it may take years to determine the extent to which
existing laws governing issues like property ownership, libel, negligence and
personal privacy are applicable to the internet. Currently, U.S. privacy law
consists of disparate state and federal statutes regulating specific
industries that collect personal data. Most of them predate and therefore do
not specifically address online activities. However, European nations are now
implementing a European Union Data Privacy Directive regulating the
transmission and storage of personal information and data. In addition, a
number of comprehensive legislative and regulatory privacy proposals are now
under consideration by federal, state and local governments in the United
States. In some cases, such as the European Directive, these comprehensive
privacy proposals include special rules that provide added protections for
sensitive information, including information about health and medical
conditions.

  The applicability to the internet of existing laws in various jurisdictions
governing issues such as property ownership, sales and other taxes, libel and
personal privacy is also uncertain and may take years to resolve. Demand for
our internet-based systems may be affected by additional regulation of the
internet in these areas.

 State and federal laws that protect individual health information may limit
 our plans to collect, use and disclose that information.

  If we fail to comply with current or future laws or regulations governing
the collection, dissemination, use and confidentiality of patient health
information, this failure could have a material adverse effect on our
business, operating results and financial condition.

  Consumers sometimes enter private health information about themselves or
their family members when using our services. Physicians or other health care
professionals who use our products will directly enter health information
about their patients, including information that constitutes a medical record
under applicable law, that we will store on our computer systems. Also, our
systems record use patterns when consumers access our databases that may
reveal health-related information or other private information about the user.
Numerous federal and state laws and regulations, the common law, and
contractual obligations govern collection, dissemination, use and
confidentiality of patient-identifiable health information, including:

  .  state privacy and confidentiality laws;

  .  our contracts with customers and partners;

  .  state laws regulating health care professionals, such as physicians,
     pharmacists and nurse practitioners;

  .  Medicaid laws;

  .  the Health Insurance Portability and Accountability Act of 1996 and
     related rules proposed by the Health Care Financing Administration; and

  .  Health Care Financing Administration standards for internet transmission
     of health data.

  The U.S. Congress has been considering proposed legislation that would
establish a new federal standard for protection and use of health information.
In addition, the laws of other countries also govern the use of and disclosure
of health information. Any failure by us or our personnel or partners to
comply with any of these legal and other requirements could result in material
liability. Although we have systems in place for safeguarding patient health
information from unauthorized disclosure, these systems may not preclude
successful claims against us for violation of applicable law or other
requirements. Other third-party sites or links that consumers access through
our web sites also may not maintain systems to safeguard this health
information, or may circumvent systems we put in place to protect the
information from disclosure. In some cases, we may place our content on
computers that are under the physical control of others, which may increase
the risk of an inappropriate disclosure of health information. For example, we
currently contract out the hosting of our websites to third parties. In
addition, future laws or changes in current laws may necessitate costly
adaptations to our systems.

                                      33
<PAGE>

  In 2000, the Department of Health and Human Service expects to finalize
proposed regulations at the federal level authorized under the Health
Insurance Portability and Accountability Act of 1996. These proposed
regulations will establish a new federal standard for privacy of health
information. We believe that these regulations, which will not be effective
until two years from finalization, will directly regulate some aspects of our
business. Achieving compliance with these regulations could cost us
significant amounts or delay or prevent implementation of our business model,
and any noncompliance by us could result in civil and criminal penalties. In
addition, development of related federal and state regulations and policies on
confidentiality of health information could negatively affect our business.

  We intend to develop medical information systems and market research
services that we will use to collect, analyze and report aggregate medical
care, medical research, outcomes and financial data pertaining to items such
as prescribing patterns and usage habits. Some states have enacted legislation
regulating the aggregation of health information and the manipulation, use and
ownership of that aggregated data, even when this data does not reveal the
patient's identity. Because this area of the law is rapidly changing, our
collection, analysis and reporting of aggregate healthcare data maintained in
our database may not at all times and in all respects comply with laws or
regulations governing the ownership, collection and use of this data. Future
laws or changes in current laws governing the ownership, collection and use of
aggregate healthcare data may necessitate costly adaptations to our systems or
limit our ability to use this data.

 We may experience substantial delays or difficulties in obtaining required
 governmental approvals; failure to obtain governmental approvals would hinder
 our ability to provide our existing systems or introduce future systems and
 could reduce our sales.

  As a manufacturer of wireless telecommunications systems, we are regulated
under the Communications Act of 1934, as amended, the Telecommunications Act
of 1996 and Federal Communications Commission regulations, as well as the
applicable laws and regulations of the various states administered by state
public service commissions. Regulatory requirements affecting our operations
may change. Any changes may hurt our business by hindering our ability to
compete with other wireless telecommunications product manufacturers, to
continue providing our existing systems or to introduce future systems or
system enhancements. Our systems are also considered medical devices and are
regulated by the FDA. Before we can market our systems, we must obtain pre-
market notification clearance under Section 510(k) of the Federal Food, Drug,
and Cosmetic Act. In addition, material changes to our systems may also
require FDA review and clearance prior to marketing or sale in the U.S. The
process of obtaining 510(k) clearance can be expensive and time-consuming, and
may require the submission of extensive supporting data. If the 510(k) process
is extended for a considerable length of time for any of our new systems, the
commencement of commercial sales of our new systems will be delayed
substantially or indefinitely.

  Because we are a provider of healthcare related systems, extensive and
frequently changing federal regulations govern the licensing, conduct of
operations, and other aspects of our business. Federal certification and
licensing programs establish standards for day-to-day operation of our
research and manufacturing facilities. Regulatory agencies verify our
compliance with these standards through periodic inspections. Although we have
been found to be in compliance with all these standards to date, our
facilities may not pass future inspections conducted to ensure compliance with
federal or any other applicable licensing or certification laws.

  We must also comply with extensive federal and state regulation relating to
the confidentiality and release of patient medical records. New legislation
governing the distribution of medical records has been proposed at both the
federal and state levels. It may be costly to implement security or other
measures designed to comply with any new legislation. Moreover, we may be
restricted or prevented from delivering patient records electronically. We
cannot assure you that we will not be required to incur significant costs to
comply with current or future laws or that we will not be materially hurt by
the cost of the compliance.

  Furthermore, we may expand sales of our systems to international markets. An
expansion would require us to comply with a wide variety of foreign laws and
practices, tariffs and other trade barriers. If we fail to obtain the
necessary regulatory approvals in foreign markets on a timely basis, our
revenue could be materially reduced.

                                      34

 FDA and FTC regulations on advertising and promotional activities may be
 burdensome and may negatively affect our ability to provide some applications
 or services, which could lead to higher than anticipated costs or lower than
 anticipated revenue.

  Complying with Food and Drug Administration and Federal Trade Commission
regulations may be time consuming, burdensome and expensive and could
negatively affect our ability to continue providing some of our internet
systems, or to introduce new internet systems in a timely manner. This may
result in higher than anticipated costs or lower than anticipated revenues.

  Any current or future regulatory requirements that the FDA or the FTC impose
on us or our advertisers and sponsors could harm us by:

  .  making it harder to persuade pharmaceutical, biotechnology and medical
     device companies to advertise or promote their products on our web
     sites, or to sponsor programs that we offer to healthcare professionals
     and the public;

  .  restricting our ability to continue to provide some of our services or
     content, or to introduce new services or content in a timely manner; or

  .  making it more expensive and time-consuming to comply with new
     requirements.

  As a consequence of these harms, we might lose advertising or sponsorship
revenue, spend significant amounts of our limited resources on regulatory
experts in the area of FDA or FTC compliance, or receive adverse publicity
that negatively affects share value. In addition to existing FDA and FTC
regulation of advertising and promotion by pharmaceutical, biotechnology and
medical device companies, our business faces a potential risk of increased FDA
and FTC regulation of these activities in an online context.

 Changes in existing FDA regulatory requirements or policies, or our failure
 to comply with current or future requirements or adoption of new requirements
 could increase the cost of our internet-based business model and cause our
 revenue to decline.

  We face potential FDA regulation of software that we develop for use on our
website. Some computer applications and software are considered medical
devices and are subject to regulation by the FDA. If FDA regulations were
applicable to any of our products and services, complying with those
regulations would be time consuming, burdensome and expensive and could delay
or prevent introduction of new products or services.

  While the FDA's policies regarding the regulation of software are evolving,
based on the FDA's informal policy statements regarding the scope of its
regulation of stand-alone software, we do not believe that our current
internet systems are subject to FDA regulation as medical devices because they
do not meet the statutory definition of a device. However, the FDA may take
the view that some of our current or future internet systems do in fact meet
the definition of a medical device and, therefore, are subject to regulation,
or the FDA may change its policies or regulations with respect to regulation
of software or internet technologies. Also, we may expand our internet system
offerings into areas that subject us to FDA regulation. If the FDA finds that
our software is subject to regulation as a medical device, the applicable
regulatory controls could include both premarket and postmarket requirements
and the FDA might require us to:

  .  obtain premarket clearance or approval of the medical device software
     from the FDA, which might include the conduct of supporting clinical
     trials or other studies;

  .  register ourselves as a medical device manufacturer and to list our
     devices with the FDA;

  .  create our software in compliance with the FDA design and manufacturing
     standards;

  .  permit the FDA to inspect our facilities and records; and

  .  make periodic reports to the FDA.

                                      35
<PAGE>

 Political, economic and regulatory changes and consolidation in the
 healthcare industry could force us to make costly modifications to how we
 price and sell our systems.

  The healthcare industry is highly regulated and is influenced by changing
political, economic and regulatory factors. These factors affect the
purchasing practices and operation of healthcare organizations. Changes in
current healthcare financing and reimbursement systems could cause us to make
unplanned modifications to our systems or result in delays or cancellations of
orders. Federal and state legislatures have periodically considered programs
to reform or amend the U.S. healthcare system at both the federal and state
level. These programs may contain proposals to increase governmental
involvement in healthcare, lower reimbursement rates or otherwise change the
environment in which healthcare industry participants operate. Healthcare
industry participants may respond by reducing or postponing investment
decisions, including investments in our systems. We do not know what effect
these proposals would have on our business. Many healthcare providers are
consolidating to create integrated healthcare delivery systems with greater
market power. These providers may try to use their market power to negotiate
price reductions for our systems. If we are forced to reduce our prices, our
revenue and earnings would be harmed. As the healthcare industry consolidates,
competition for customers will become more intense.

 Our activities may expose us to malpractice and other liability inherent in
 healthcare delivery.

  We may be exposed to malpractice or other liability against which we may not
be adequately insured, resulting in a decline in our financial results. Our
systems provide data for use by physicians, consumers and other healthcare
participants. This data may be obtained from our physician customers,
strategic partners, other third parties or, with patient consent, from the
aggregation of patient health records. Claims for injuries relating to the use
of this data may be made in the future. Also, patients who file lawsuits
against doctors often name as defendants all persons or companies with any
relationship to the doctors. As a result, patients may file lawsuits against
us based on treatment provided by physicians who use our systems. In addition,
a court or government agency may take the position that our delivery of health
information directly, including through licensed physicians, or delivery of
information by a third-party site that a consumer accesses through our web
sites, exposes us to malpractice or other personal injury liability for
wrongful delivery of healthcare services or erroneous health information. The
amount of insurance we maintain with insurance carriers may not be sufficient
to cover all of the losses we might incur from these claims and legal actions.
In addition, insurance for some risks is difficult, impossible or too costly
to obtain and, as a result, we may not be able to purchase insurance for some
types of risks.

 We may fail to protect our proprietary technology and to maintain access to
 the proprietary information of third parties that support our competitive
 position; as a result, our growth may be hurt.

  Our owned and licensed intellectual property is important to our business.
We could have intellectual property infringement claims asserted against us as
the number of our competitors grows and the functionality of our systems
overlaps with competitive offerings. These claims, even if not meritorious,
could be expensive and divert our attention from our core business operations.
If we become liable to third parties for infringement of their intellectual
property rights, we could be required to pay substantial damages and to
develop alternative non-infringing technology, obtain a license or cease
selling the systems that contain the infringing intellectual property. We may
be unable to develop non-infringing technology or obtain a license on
commercially reasonable terms, if at all. In addition, we may not be able to
protect against misappropriation or infringement of our intellectual property
by third parties. If misappropriation or infringement occurs, we may not be
able to detect it or to effectively enforce our rights.

 Our international expansion plans involve risks.

  A key component of our strategy is expanding our operations into
international markets. To date, we have limited experience in developing and
distribution channels for our systems and we may not be able to successfully
execute our business model in these markets. Our success in these markets will
be directly linked to

                                      36
<PAGE>

the success of our business partners in such activities. If our business
partners fail to successfully establish operations and sales and marketing
efforts in these markets, our business could suffer.

  In addition, we face a number of risks inherent in doing business in
international markets, including, among others:

  .  unexpected changes in regulatory requirements;

  .  potentially adverse tax consequences;

  .  export controls relating to encryption technology;

  .  tariffs and other trade barriers;

  .  difficulties in staffing and managing foreign operations;

  .  changing economic conditions;

  .  exposures to different legal standards (particularly with respect to
     intellectual property and distribution of information over the
     internet);

  .  burdens of complying with a variety of foreign laws;

  .  fluctuations in currency exchange rates; and

  .  seasonal reductions in business activity during the summer months in
     Europe and certain other parts of the world.

If any of these risks occur, our business could suffer.

 Our existing capital resources may not be sufficient to fund our system
 development efforts and marketing plans; if we are required to raise
 additional capital, your investment may be diluted.

  We expect that the proceeds generated from our initial public offering,
combined with our current cash resources and credit facilities, will be
sufficient to meet our capital requirements for at least the next 12 months.
However, we may need to raise additional capital at an earlier time to support
expansion, develop new or enhanced systems, respond to competitive pressures,
acquire complementary businesses or technologies or take advantage of other
unanticipated opportunities. In addition, we have from time to time failed to
comply with covenants required by our working capital line of credit and
subordinated debt facility agreements. Both of our lenders have granted us
waivers for this noncompliance, but if we are unable to comply with these
covenants in the future, and if our lenders do not waive our noncompliance, we
may need to raise additional capital sooner than anticipated through the sale
of debt or equity securities or by entering into strategic alliances or other
arrangements. If we are unable to raise additional capital on reasonable terms
and in a timely fashion, our financial position will decline. Furthermore, any
additional issuance of equity securities will dilute your investment.

 Trading in our shares may be affected by extreme price fluctuations, and you
 could experience difficulties selling your shares.

  The trading price of our common stock may be volatile. The stock market in
general, and the market for technology companies in particular, has
experienced extreme volatility that often has been unrelated to the operating
performance of particular companies. These broad market and industry
fluctuations may decrease the trading price of our common stock, regardless of
our actual operating performance, and may make it difficult for you to resell
your shares at or above the initial offering price.

                                      37
<PAGE>

 Significant fluctuations in the market price of our common stock could result
 in securities class action claims against us, which could seriously harm our
 cash position.

  Securities class action claims have been brought against companies in the
past where volatility of the market price of that company's securities has
taken place. This kind of litigation could be very costly and could divert our
management's attention and resources. Any negative determination in this
litigation could also subject us to significant liabilities, any or all of
which could seriously harm our cash position.

 Substantial sales of our common stock after the expiration of the lock-up
 agreements associated with the initial public offering could result in a
 lower market price of our common stock

  Sales of substantial amounts of our common stock in the public market after
expiration of the lock up agreements associated with the initial public
offering, or the perception that these sales will occur, could adversely
affect the market price of our common stock. At expiration of the lock-up
agreements, 6,141,773 shares will be eligible for sale in the public market as
follows:

<TABLE>
<CAPTION>

                  volume limitations.
</TABLE>

  In addition, a substantial number of outstanding shares of common stock and
shares issuable upon exercise of outstanding options will become available for
resale in the public market at prescribed times.

 State laws and our certificate of incorporation may inhibit potential
 acquisition bids that could be beneficial for stockholders.

  Delaware law and Washington law may inhibit potential acquisition proposals.
We are restricted by the anti-takeover provisions of the Delaware General
Corporation Law, which regulates corporate acquisitions. Delaware law prevents
us from engaging in a business combination with any interested stockholder for
three years following the date that the stockholder became an interested
stockholder.

  For purposes of Delaware law, a business combination includes a merger or
consolidation or the sale of more than 10% of our assets. In general, Delaware
law defines an interested stockholder as any entity or person beneficially
owning 15% or more of the outstanding voting stock of a corporation and any
entity or person affiliated with or controlling or controlled by the entity or
person. Under Delaware law, a Delaware corporation may opt out of the
antitakeover provisions. We do not intend to opt out of these antitakeover
provisions of Delaware law. The laws of Washington, where our principal
executive offices are located, also impose restrictions on some transactions
between foreign corporations and significant stockholders. Chapter 23B.19 of
the Washington Business Corporation Act prohibits a target corporation, with
exceptions, from engaging in significant business transactions with an
acquiring person for a period of five years after the acquisition, unless the
transaction or acquisition of the shares is approved by a majority of the
members of the target corporation's board of directors prior to the time of
acquisition. A corporation may not "opt out" of this statute and, therefore,
we anticipate this statute will apply to us. Depending upon whether we meet
the definition of a target corporation, Chapter 23B.19 of the WBCA may have
the effect of delaying, deferring or preventing a change in control of us.

  In addition, we have adopted provisions in our certificate of incorporation
that may discourage potential acquisition proposals and delay or prevent a
change in control of our company. These provisions include the following:

  .  our board of directors may issue up to three million shares of preferred
     stock and determine the applicable powers, preferences and rights and
     the qualifications, limitations or restrictions of the stock, including
     voting rights, without any vote or further action by stockholders;

                                      38
<PAGE>

  .  our directors are elected to staggered three-year terms;

  .  stockholders cannot call special meetings;

  .  the nomination of a director or the taking of certain actions requires
     advance notice; and

  .  stockholders cannot take action by written consent.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

  Our exposure to market risk for changes in interest rates relates primarily
to the increase or decrease in the amount of interest income we can earn on
our investment portfolio and on the increase or decrease in the amount of any
interest expense we must pay with respect to outstanding debt instruments. The
risk associated with fluctuating interest expense is limited, however, to the
exposure related to those debt instruments and credit facilities which are
tied to market rates. We do not plan to use derivative financial instruments
in our investment portfolio. We plan to ensure the safety and preservation of
its invested principal funds by limiting default risk, market risk and
investment risk. We plan to mitigate default risk by investing in low-risk
securities. At December 31, 1999, we had an investment portfolio of money
market funds, commercial securities and U.S. Government securities of $1.4
million. We had notes payable and capital leases outstanding of $34.0 million
at December 31, 1999. If market interest rates were to increase immediately
and uniformly by 10% from levels as of December 31, 1999, the decline of the
fair market value of the fixed income portfolio and loans outstanding would
not be material.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors and Stockholders of
Data Critical Corporation:

  We have audited the accompanying balance sheets of Data Critical Corporation
(a Delaware corporation) as of December 31, 1998 and 1999, and the related
statements of operations, stockholders' equity (deficit) and cash flows for
each of the three years in the period ended December 31, 1999. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

  We conducted our audits in accordance with 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, the financial statements referred to above present fairly,
in all material respects, the financial position of Data Critical Corporation
as of December 31, 1998 and 1999, and the results of its operations and its
cash flows for each of the three years in the period ended December 31, 1999,
in conformity with generally accepted accounting principles.

1. Nature of Business and Summary of Significant Accounting Policies:

 Nature of Business

  We design, manufacture, market, install and support communication and
information systems, using wireless and internet technology and proprietary
software to allow access to health information, including patient vital signs
and other diagnostic data, using wireless technology and proprietary software.
Our systems provide for information retrieval from remote sources, both inside
and outside the hospital environment, and are integrated and coordinated
through either a wireless network utilizing our interactive device, a personal
computer or the internet. Our focus within health care is on the hospital,
physician and at-home consumer markets. To date, the Company has directed a
significant portion of its efforts to research and development, development of
markets for its products, application for patents, raising capital and
planning. The Company performed selected contract development services during
this period as well as commenced sales of related products during 1995. During
1997, the Company focused on addressing its technology to specific medical
applications. The resulting products are regulated by the U.S. Food and Drug
Administration and therefore require pre-market approval from the FDA prior to
making sales. The first of these approvals was granted in November 1997.

  The Company commenced sales of its current products and services late in the
third quarter of 1997. The Company continues to face a number of risks similar
to other companies in a comparable stage of development including: reliance on
key personnel; successful marketing of its products; competition from other
companies with greater technical, financial, management and marketing
resources; successful development of new products and the enhancement of
existing products; and the ability to secure adequate financing to support
future growth, if and when required.

 Cash and Cash Equivalents

  The Company considers all highly liquid investments with a maturity when
purchased of 90 days or less to be cash equivalents. Cash and cash equivalents
consist of cash on deposit with banks and money market investments.

 Inventories

  The Company's initial medical product is made up of the Company's
proprietary software applications which it integrates with hardware that is
acquired from third parties as well as hardware made by third parties to the
Company's specifications. Inventories consist primarily of the Company's
hardware product, components to make the product and other third-party
equipment, all of which is stated at the lower of cost or market, using the
first-in, first-out method.

 Property, Equipment and Software

Property, equipment and software are stated at historical cost less
accumulated depreciation. Depreciation is computed using the straight-line
method over the estimated useful lives of the assets, generally three to five
years. Ordinary repairs and maintenance and purchases of less than $500 are
expensed as incurred. Leasehold improvements are amortized over the lesser of
the term of the lease or the estimated useful life of the asset.

 Investment In and Advances To Unconsolidated Affiliate

  The Company accounts for its investments in entities in which it owns less
than a 20% interest under the cost method.

                  NOTES TO FINANCIAL STATEMENTS--(Continued)


 Other Assets

  Other assets include licensed intellectual property rights and other
intangible assets which are stated at historical cost less accumulated
amortization provided on a straight-line basis over the estimated useful lives
of the asset, generally seven years. Other assets also includes technology
purchased in the Physix acquisition (see Note 10), which are stated at their
fair market values at the acquisition date less accumulated amortization
provided on a straight-line basis over three years. Other assets also include
capitalized legal expenses associated with patent applications. These costs
will be amortized over their estimated useful lives upon patent issuance by
the U.S. Patent Office. Amortization expense on other assets was $15,000,
$19,000 and $34,000 in 1997, 1998 and 1999, respectively. Accumulated
amortization was $27,000, $47,000 and $81,000 at December 31, 1997, 1998 and
1999, respectively.

 Revenue Recognition

  The Company's revenue recognition policies are in conformity with Statement
of Position 97-2 "Software Revenue Recognition" as amended, of the American
Institute of Certified Public Accountants. License revenue is earned when
delivery has occurred, the fee is fixed and determinable, evidence of an
arrangement exists, collection of the receivable is probable and no
significant post-delivery obligations remain. For sales to end users, revenue
is recognized upon installation. For sales to distributors, revenue is
recognized upon delivery. Maintenance and support revenue is recognized over
the term of the agreement.

  The Company recognizes revenue from software development contracts involving
significant production, modification or customization of software, based on
performance milestones specified in the contract where these milestones fairly
reflect progress toward contract completion.

 Major Customers

  In January 1997, Data Critical signed a distribution and license agreement
with GE Marquette Medical Systems, Inc. for the non-exclusive licensing and
distribution of a medical wireless data product. Approximately 38.3%, 54.5%
and 18.5% of the Company's revenues for the years ended December 31, 1997,
1998 and 1999, respectively, is attributable to GE Marquette Medical Systems,
Inc. Approximately 20.3%, 44.7% and 72.1% of the Company's revenue for the
years ended December 31, 1997, 1998 and 1999, respectively, is attributable to
Agilent Technologies, Inc. (Agilent) pursuant to a 1994 license agreement
which provided Agilent exclusive distribution rights to a specific
implementation of the Company's medical wireless data technology. In September
1997, the 1994 license agreement between the Company and Agilent was
terminated by mutual agreement thus allowing the Company to sell directly to
Agilent customers. Approximately 22.1% of the Company's revenue for the years
ended December 31, 1997, is attributable to federal and state governmental
agencies. The Company had no sales to federal and state governmental agencies
in 1998 or 1999.

 Warranty Obligations

  The Company generally provides product warranties for 12 months after date
of purchase. Estimated warranty obligations are provided at the time of the
sale of the Company's products.

 Royalty Expense

  During 1997 and 1998, the Company entered into two nonexclusive licenses to
sell products using patented technology. In exchange for the licenses the
Company is required to make quarterly royalty payments based on the number of
products invoiced. Amounts charged to expense for the two nonexclusive
licenses were $14,000, $142,000 and $144,000 in 1997, 1998 and 1999,
respectively.

                  NOTES TO FINANCIAL STATEMENTS--(Continued)


 Research and Development Costs

  The Company's accounting policy is to capitalize eligible computer software
development costs upon the establishment of technological feasibility, which
the Company has defined as completion of a working model. The amount of
eligible costs to be capitalized has not been material and accordingly, the
Company has charged all software development costs to research and development
in the accompanying statements of operations.

 Advertising Costs

  Costs related to advertising the Company's products are expensed in the
period incurred. Advertising costs incurred during the years ended December
31, 1997, 1998 and 1999 were $31,600, $67,000 and $49,000, respectively.

 Income Taxes

  Deferred income taxes are accounted for using the asset and liability
method. Under the asset and liability method, deferred income taxes are
recognized for the tax consequences of temporary differences by applying
enacted statutory tax rates applicable to future years to differences between
the financial statement carrying amounts and the tax bases of existing assets
and liabilities. The effect on deferred taxes for a change in tax rates is
recognized in income in the period that includes the enactment date. To date,
the Company has fully reserved for its net deferred tax assets.

 Stock Options

  The Company has adopted the provisions of Statement of Financial Accounting
Standards No. 123 (SFAS 123), "Accounting for Stock-Based Compensation." In
accordance with the provisions of SFAS 123, the Company has elected the
disclosure only provisions related to employee stock options and follows the
provisions of Accounting Principals Board Opinion No. 25 (APB 25) in
accounting for stock options issued to employees. Under APB 25, compensation
expense, if any, is recognized as the difference between the exercise price
and the fair value of the common stock on the measurement date, which is
typically the date of grant, and is recognized over the service period, which
is typically the vesting period.

  The Company discloses the pro forma effect on net income as if it had
accounted for option grants to employees under the "fair value" method
prescribed by SFAS 123. The fair-value based model values stock options using
an acceptable valuation model. Pro forma compensation cost is measured at the
grant date based upon the fair value of the award and is recognized over the
service period, which is typically the vesting period.

  Warrants and options granted to non-employees are accounted for under the
fair value provisions of SFAS 123.

 Concentrations of Credit Risk

  Financial instruments which subject the Company to concentrations of credit
risk consist principally of cash and trade receivables. The risk for cash and
cash equivalents is limited by the Company's policy of maintaining cash and
equivalents in multiple, highly rated, liquid investments. The Company has
credit risk regarding trade accounts receivables as most of these receivables
are with healthcare institutions or with distributors to healthcare
institutions. To mitigate this risk, the Company has a credit policy under
which it verifies the creditworthiness of its customers.

 Financial Instruments

  The Company enters into various types of financial instruments in the normal
course of business and in raising capital. Fair values of cash, trade
receivables, notes receivable and notes payable all approximate market

value. The fair value of mandatorily redeemable preferred stock at December
31, 1998, was estimated to be approximately $32,822,000. This estimate of fair
value was determined by management using recent sales of preferred stock,
consideration of significant milestones achieved by the Company and other
market considerations. The mandatorily redeemable preferred stock was
converted into common stock in November 1999.

Use of Estimates

  The preparation of financial statements in conformity with generally
accepted accounting principles 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 those estimates.

 Loss Per Share

  In accordance with Statement of Financial Accounting Standards No. 128,
"Computation of Earnings Per Share," basic loss per share is computed by
dividing net loss attributable to common stock (net loss less preferred stock
redemption obligation accretion and dividend requirements) by the weighted
average number of shares of common stock outstanding during the period.
Diluted loss per share is computed by dividing net loss by the weighted
average number of common and dilutive common equivalent shares outstanding
during the period. Common equivalent shares consist of the shares of common
stock issuable upon the conversion of the mandatorily redeemable preferred
stock (using the if-converted method) and shares issuable upon the exercise of
stock options and warrants (using the treasury stock method); common
equivalent shares are excluded from the calculation as their effect is
antidilutive. Accordingly, basic and diluted loss per share are equivalent.
The Company has not had any issuances or grants for nominal consideration as
defined under U.S. Securities and Exchange Commission Staff Accounting
Bulletin 98.

 Segment Reporting

  The Company adopted Statement of Financial Accounting Standards No. 131,
"Disclosures About Segments of an Enterprise and Related Information," (SFAS
131) during 1998. SFAS 131 requires companies to disclose certain information
about operating segments. Based on the criteria within SFAS 131, the Company
has determined that it has one reportable segment, wireless data products.

 Notes Payable

  The Company had notes payable to a bank, secured by certain equipment, with
a total outstanding balance of $249,000 and $0 at December 31, 1998 and 1999,
respectively. The loans bore interest at the bank's prime rate plus 1.0% to
2.5% (8.75% to 10.25% at December 31, 1998).

  During 1997 and 1998, the Company issued convertible notes totaling $2.1
million and bearing interest at 9.0%. With these notes, the Company also
issued warrants to purchase 198,792 shares of common stock for $1.60 per
share. In March 1998, all accrued interest was paid and the principal balances
were converted into approximately 530,119 shares of Series D mandatorily
redeemable preferred stock.

  In April 1999, the Company established a subordinated debt facility totaling
$1.5 million that expired in October 1999. Loans made under this facility are
secured by substantially all of the Company's assets, subordinated to the
commercial bank loans. Advances under the subordinated debt agreement were
limited to $500,000 or more per advance and are payable at 11.0% interest only
for the first 12 months and in equal monthly principal and interest payments
for the following 24 months. As of December 31, 1999, $987,000 was outstanding
under this debt facility. This entire outstanding balance was repaid in
January 2000. In connection with this debt facility, the lender received an
option to purchase up to 105,000 shares of Series D preferred stock at a
purchase price of $5.00 per share. The lender exercised this option in full on
October 25, 1999.

  The same lender has also provided a lease line of credit for up to $1.0
million, comprised of $800,000 to finance equipment and $200,000 to finance
equipment, leasehold improvements and software. Advances made under the lease
line are payable over 36 equal monthly installments. As of December 31, 1999,
$161,000 was outstanding under this lease line. As part of this lease line,
the lender received a warrant to purchase 12,500 shares of Series D preferred
stock at an exercise price of $4.00 per share. This warrant expires on
November 9, 2004.

  Issuance costs associated with the mandatorily redeemable preferred stock
offerings were recorded as a reduction to preferred stock. The preferred stock
is being accreted to its redemption amount over the period ending with the
mandatory redemption dates. Accretion of mandatory redemption costs is
computed using the straight-line method, which approximates the effective
interest rate method. The redemption price is equal to the liquidation
preference.

 1999 Employee Stock Purchase Plan

  Data Critical's 1999 Employee Stock Purchase Plan was adopted by the board
of directors and approved by the stockholders in May 1999. 100,000 shares plus
an annual increase in each of the next five years equal to the lesser of
150,000 shares or one percent of the outstanding shares of common stock on the
last day of the preceding fiscal year of common stock have been reserved for
issuance under the Purchase Plan. As of December 31, 1999, no rights to
purchase stock under this plan had been granted by Data Critical.

  The Purchase Plan, which is intended to qualify under Section 423 of the
Internal Revenue Code, will be implemented by a series of overlapping offering
periods of 24 months in duration, with new offering periods

                                      52

(other than the first offering period) commencing on March 1 and September 1
of each year. Each offering period will consist of four consecutive purchase
periods of six months in duration. The initial offering period is expected to
commence on March 1, 2000.

  The Purchase Plan permits eligible employees to purchase common stock
through payroll deductions, which may not be less than 1% and not more than
20% of an employee's compensation, at a price equal to the lower of 85% of the
fair market value of Data Critical's common stock at the beginning of each
offering period or at the end of each purchase period. Employees may end their
participation in the offering at any time during the offering period, and
participation ends automatically on termination of employment with Data
Critical. If not terminated earlier, the Purchase Plan will have a term of 20
years.

  These warrants generally expire within five years from grant (2000 to 2002).
The warrants were recorded as a component of additional paid-in capital at
their estimated fair value at the date of issuance.

7. Stock Option Plan:

  The Company has three stock option plans, the 1994 Stock Plan, the 1999
Stock Plan and the 1999 Directors Stock Plan (collectively, the "Plans"). The
1994 and 1999 Stock Plans provide for the grant of incentive and nonstatutory
stock options to employees, directors and consultants. The 1999 Directors
Stock Plan provides for the grant of nonstatutory stock options to non-
employee directors of the Company. Options generally terminate if unexercised
within 90 days after the employee leaves the company or, in the case of the
Directors Stock Plan, 90 days after the director ceases to be a director of
the Company.

  Under the 1994 and 1999 Stock Plans, options generally become exercisable at
the rate of 25% of the total number of shares underlying the options 12 months
after the vesting commencement date, and 25% every 12 months thereafter.
Options generally expire no later than seven years after grant, or five years
in the case of an incentive stock option granted to a 10% stockholder.

  Options granted under the Directors Stock Plan are fully vested at the date
of grant and expire 10 years after they are granted.

  Under the 1994 Plan, 950,000 shares of common stock were reserved for
issuance. No further options will be granted under the 1994 Stock Plan. Under
the 1999 Stock Plan, 1,000,000 shares plus an annual increase in each of the
next five years equal to the lesser of 250,000 shares or two percent of the
outstanding shares of common stock on the last day of the preceding fiscal
year of common stock have been reserved for issuance. Under the 1999 Directors
Stock Plan, 100,000 shares of common stock have been reserved for issuance.

  The Directors Plan provides that each person who is or becomes a nonemployee
director of Data Critical will be granted a nonstatutory stock option to
purchase 15,000 shares of common stock on the later of the date on which the
option holder first becomes a nonemployee director of Data Critical or the
date of the closing of this offering. Thereafter, on the date of our annual
stockholders' meeting each year, each nonemployee director of Data Critical
will be granted an additional option to purchase 5,000 shares of common stock
if, on that date, he or she has served on our board of directors for at least
six months.

  Incentive options are granted at not less than the fair value of common
stock on the date of grant, and nonqualified options are granted at not less
than 50% of fair value on the date of grant. All options expire no later than
seven years from the date of grant.

and 556,292 shares were exercisable, respectively.

  Under the Plans, options to purchase 416,737 shares of common stock were
available for future grant. As of December 31, 1999, the 1,523,999 options
outstanding under the 1994, 1999 and Director Stock Plan have exercise prices
between $0.80 and $12.00 and a weighted-average remaining contractual life of
6.74 years. During 1998 and 1999, the Company recorded $605,000 and
$1,316,000, respectively, of deferred compensation from the issuance of stock
options with exercise prices less than the fair value of common stock. This
deferred compensation is recognized as expense ratably over the vesting period
of the options. In 1998 and 1999, the Company recognized $53,000 and $541,000,
respectively, of expense related to this deferred compensation. Up to the
Company's initial public offering the fair value of common stock on the dates
of stock option grants was determined by management using recent sales of
preferred stock, consideration of significant milestones achieved

  For purposes of pro forma disclosure, the estimated fair value of each
option grant is estimated on the date of grant using the minimum value method,
which considers the time-value of money, with the following assumptions for
grants in 1997, 1998 and 1999: risk-free interest rates of 6.25% to 6.50%;
expected lives of five years; and no dividends. The weighted average fair
value of options granted in 1997, 1998 and 1999 were $0.27, $0.58 and $7.38,
respectively. The volatility number used for those options granted between
December 9, 1999 and December 31, 1999 was 1.018. The pro forma effect upon
net loss and net loss per share, taking into account only the additional
compensation expense that would be recognized using the fair value method, are
as follows (in thousands):

8. Income Taxes:

  At December 31, 1999, the Company had net operating loss carryforwards of
approximately $20,000,000. The Company may be limited in its ability to
utilize certain of its future carryforwards in any year due to previous sales
of its stock. Management believes that, based on a number of factors, the
available objective evidence creates significant uncertainty regarding the
realization of the net deferred tax assets. Accordingly, a valuation allowance
has been provided for the net deferred tax assets of the Company. This
valuation allowance increased in 1997, 1998 and 1999 by $1,417,000, $2,232,000
and $2,662,000 , respectively. These carryforwards, which may provide future
tax benefits, expire from 2008 to 2019.

  The difference between the statutory tax rate of approximately 35% (34%
federal and 1% state, net of federal benefits) and the tax benefit of zero
recorded by the Company is primarily due to the Company's full valuation
against its net deferred tax assets.

9. Related Party Transactions:

 Investment in and Advance to Unconsolidated Affiliate

  On July 10, 1996, the Company loaned Nomadics, Inc. $50,000 in exchange for
a promissory note, which matures on July 10, 2000. The note is convertible
into approximately a 3.6% equity interest in Nomadics, Inc., at the earlier of
July 10, 2000 or upon an initial public offering of the Company's stock.
Interest accrues at 8.0% per year. On November 7, 1996, the Company acquired
Nomadics, Inc. common stock representing a 10.8% interest for a cash payment
of $151,000.

 Note Receivable from Officer

  As a part of the employment contract with a senior executive, the Company
loaned $45,000 on July 18, 1997, in exchange for a promissory note, which
matures on July 17, 2001. Interest of 6.7% on the unpaid principal balance is
due annually.

10. Acquisitions:

  On December 17, 1999, the Company acquired substantially all of the
business, assets and rights of Physix, Inc. (Physix). Under the terms of the
agreement the Company issued 200,000 shares of common stock, all of which were
placed in escrow. Of these 200,000 shares, 100,000 shares will be released if
not required to satisfy Physix indemnification obligations, and the other
100,000 shares (the "contingency shares") will only be released upon the
achievement of certain milestone obligations. If these performance milestones
are not met within one year, the number of contingency shares to be released
to Physix will be reduced on a sliding scale, up to the total 100,000 shares,
and the unreleased shares will be returned to the Company for retirement. The
Company also paid approximately $1.5 million in cash to repay certain Physix
obligations and assumed certain other Physix liabilities amounting to
approximately $600,000.

  This acquisition was accounted for as a purchase and, accordingly, the
financial statements reflect valuation of all assets, including identifiable
intangibles, at their estimated fair market values. Physix's results of
operations are included in the accompanying statement of operations from the
date of the acquisition.

  Consideration that is held in escrow pending the outcome of a contingency is
disclosed but not recorded as a liability or shown as outstanding securities
unless the outcome of the contingency is determinable beyond reasonable doubt.
Accordingly, the Company reduced its total consideration by the value of the
contingency shares, resulting in negative goodwill in the amount of $673,000
which was allocated to reduce proportionately the values assigned to long-term
assets including identifiable intangibles and acquired in-process research and
development.

                           DATA CRITICAL CORPORATION

                       AMENDMENT TO EMPLOYMENT AGREEMENT
                       ---------------------------------

     This Amendment to Employment Agreement (the "Amendment") is made as of
February 24, 2000 (the "Effective Date") by and between Michael Singer
("Employee") and Data Critical Corporation, a Delaware corporation (the
"Company").

                                  WITNESSETH


     WHEREAS, Employee and the Company are parties to an Employment Agreement
dated as of June 14, 1999 (the "Employment Agreement").

     WHEREAS, Employee and the Company wish to amend the Employment Agreement as
set forth in this Amendment.

     NOW, THEREFORE, in consideration of the mutual consideration, promises,
representations, and covenants set forth herein, the receipt and sufficiency of
which are hereby acknowledged, Employee and the Company agree as follows:

                                   AGREEMENT

     1.   All capitalized terms used but not defined herein shall have the
meanings given them in the Employment Agreement.

     2.   Section 1 of the Employment Agreement shall be amended to read in its
entirety as follows:

          "1.  Term of Agreement.  This Agreement shall commence on the date
     hereof and shall have a term of five (5) years (the "Original Term"). Prior
     to January 1, 2001, the Company may only terminate this Agreement for Cause
     (as defined in Section 6 below). Thereafter, subject to Section 5, this
     Agreement may be terminated by either party, with or without cause, on
     thirty (30) days' written notice to the other party. This Agreement may be
     extended for an additional one (1) year term after the end of the Original
     Term if the parties mutually agree in writing to such extension."

     3.   A new Section 5(b)(vi) shall be added to the Employment Agreement to
read in its entirety as follows:

               "(vi) Termination After Resignation or Removal of Chief Executive
     Officer. If (A) Jeffrey S. Brown's employment with the Company is
     terminated for any reason or Jeffrey S. Brown no longer holds the position
     of Chief Executive Officer of the Company prior to the end of the Original
     Term and (B) within the 30-day period immediately following such
     termination or change of position Employee elects to
<PAGE>

     terminate his employment voluntarily, then Employee will be entitled to
     receive severance and benefits continuation in accordance with Section
     5(b)(ii) hereof as if an Involuntary Termination had occurred. In addition,
     in such case, Employee's stock options, including those described in
     Sections 4(c)(i), 4(c)(ii), and 4(c)(iii) hereof and all other options
     subsequently granted by the Company to Employee, will be accelerated
     completely on the date of such Constructive Termination so that one hundred
     (100%) of the number of shares of Common Stock covered by all of Employee's
     options are fully vested and exercisable."

     4.   All other provisions of the Employment Agreement shall remain
unchanged and in full force and effect.

     The parties have executed this Amendment as of the Effective Date.

2.  TERM

     The term of this Lease shall commence November 1, 1996 ("Commencement
Date"), and shall expire February 28, 2004 ("Expiration Date").  In the event
the Leased Premises should not be ready for occupancy by the Commencement Date
for any reason, Landlord shall not be liable or responsible for any claims,
damages or liabilities in connection therewith or by reason thereof; and the
term of this Lease shall commence at the time that the Leased Premises are ready
for occupancy by Tenant, Landlord and Tenant, at the request of either, will
execute a declaration specifying the square feet of Rentable Area contained
within the Leased Premises, the beginning date of the term of this Lease and
such beginning date will then constitute the Commencement Date.  In such event,
rental under this Lease shall commence, subject to a rental abatement period as
provided below, on said revised Commencement Date and the stated term in this
Lease shall thereupon commence, and the Expiration Date shall be extended to
effect a full eighty-eight (88) month term.  If the Leased Premises are not
"Substantially Completed" (as hereinafter defined) by February 1, 1997 (the
"Outside Completion Date") [subject to delays due to force majeure, Tenant
delays, or delays beyond the reasonable control of Landlord]; upon written to
Landlord, Tenant shall have the one time right to terminate this Lease within
ten (10) days following the Outside Completion Date.  If the Lease is
terminated, all deposits paid to Landlord by Tenant under this Lease shall be
promptly refunded by Landlord to Tenant and neither party shall have any further
obligations or liabilities under this Lease.  "Substantial Completion", as said
term is used herein, shall mean that date, as reasonably determined by Landlord
or Landlord's architect, when all of the improvements required to be performed
by Landlord have been completed excepting completion or correction of minor
items which do not significantly impair Tenant's ability to occupy and use the
Leased Premises for the purposes intended.

3.  RENT

     As "Base Rental" for the lease and use of the Leased Premises, Tenant will
pay Landlord or Landlord's assigns, at the Building office or post office

               Building.

          (4)  Building elevators for access to and egress from the Leased
               Premises twenty-four (24) hours a day, seven (7) days a week.

          (5)  Proper facilities to enable the appropriate utility company to
               furnish electricity for Building standard lighting, typewriters,
               dictating equipment, copiers, calculating machines, personal
               computers and other machines of similar low electrical
               consumption, but not including electricity required for
               electronic data processing equipment, special lighting in excess
               of Building standard, or any item of electrical equipment which
               single consumes more than 0.25 kilowatts per hour at rated
               capacity or requires a voltage other than 120 volts single phase,
               regardless of whether such special lighting or other equipment
               was paid for out of funds that Landlord may have supplied for the
               improvement of the Leased Premises, Tenant shall pay Landlord
               monthly [illegible words] separately-metered charges for any
               electricity in excess of that stated above (the cost of any such
               meter and its installation to be borne by Tenant), or if not
               separately metered, the charge for such excess electricity as
               Landlord's engineer may compute.  Upon approval by Landlord and
               Tenant of engineered drawings for the improvements to be made to
               the Leased Premises, Landlord shall give Tenant notice if any
               such separate meters are required.

               standard ceiling mounted fixtures installed by Landlord and
               incandescent bulb replacement in all public areas.

     B.   Subject to the provisions of Paragraph 5.C. below, no interruption or
          malfunction of these services (including, without limitation, acts of
          God, or the actions, regardless of the ultimate validity or
          enforceability thereof, of any governmental, quasi-governmental,
          regulatory or executive authority) shall constitute an eviction or
          disturbance of Tenant's use and possession of the Leased Premises or a
          breach of any of Landlord's obligations or render Landlord liable for
          damages or entitle Tenant to be relieved from any of its obligations
          (including the obligation to pay rent).  In the event of any
          interruption or malfunction, Landlord shall use reasonable diligence
          during Landlord's normal business hours to restore service when
          restoration is within its reasonable control.

     C.   Any Landlord's failure to provide the services specified in Paragraph
          5.(a)(1), (2) for restrooms only and provided Landlord cannot provide
          alternate facilities in the

                                      -4-
<PAGE>

          Building,] (4) and (5) which results in all or any part of the Leased
          Premises being rendered unsafe or in any way unsuitable for use by
          Tenant in the ordinary conduct of its business is herein referred to
          as a "Constructive Eviction". If a Constructive Eviction occurs and is
          not cured within five (5) working days after receipt by Landlord of
          written notice from Tenant of the existence of such Construction
          Eviction, Tenant shall have the following rights and remedies:

          (1)  For each day or portion thereof that the Constructive Eviction
               continues after the initial five (5) day period, and provided
               that Tenant is not using such space in a reasonably normal
               manner, specifically recognizing the number of employees
               utilizing such space is not a basis for using such space in a
               reasonably normal manner, Tenant will be entitled to an equitable
               abatement of rent commensurate with that portion of the Leased
               Premises to which such Landlord's services have been interrupted,
               calculated on a per square foot basis, beginning with the
               inception of the sixth (6th) working day and terminating at the
               time the Constructive Eviction is completely cured by Landlord
               having resumed furnishing the interrupted service or having
               rendered the Leased Premises again suitable for use by Tenant for
               its intended purposes.

          (2)  If the Constructive Eviction is caused by Landlord's fault and is
               not completely cured within thirty (30) days, or, if the
               Constructive Eviction is not caused by Landlord's fault and is
               not cured within sixty (60) days, then Tenant, at its option may
               terminate this Lease and all of its obligations for the remaining
               balances of the term.  If Tenant so elects to terminate this
               Lease, it shall so notify Landlord in writing at anytime prior to
               Landlord curing the Constructive Eviction.

          (3)  Tenant's remedies for failure to provide services as set out in
               this Paragraph 5.C. are limited to those so provided in this
               Paragraph 5.C.

     D.   Should Tenant desire any additional services beyond those described in
          subparagraph 5A or rendition of any of such service outside the normal
          times they are provided by Landlord, Landlord may (at Landlord's
          option), with reasonable prior request from Tenant, furnish such
          service; and Tenant agrees to pay Landlord charges as may be agreed on
          between Landlord and Tenant, but in no event a charge less than
          Landlord's actual cost plus overhead for the additional services
          provided.  It is agreed that the cost to Landlord of such additional
          services shall be excluded from the "Project Operating Cost," as
          defined in subparagraph 13B.

6.  REPAIR AND MAINTENANCE

                                      -5-
<PAGE>

     A.   Landlord will, at its own cost and expense, except as may be provided
          elsewhere herein, make necessary repairs or damage to the Building's
          corridors, lobby, structural members, and equipment used to provide
          the services referred to in subparagraph 5A unless the damage is
          caused by acts or omissions of Tenant, its agents, customers,
          employees or invitees, in which event Tenant will bear the cost of
          repairs.  Tenant will promptly give Landlord written notice of any
          damage requiring repair by Landlord.

     B.   Tenant will not injure the Leased Premises, Building or any other part
          of the Project and will maintain the Leased Premises in a clean,
          attractive condition and in good repair, except for damage to be
          repaired by Landlord, as provided above.  Upon expiration or
          termination of this Lease, Tenant will surrender the Leased Premises
          to Landlord in the same condition in which it existed at the
          Commencement Date, excepting only ordinary wear and tear, damage
          arising from any cause not required to be repaired by Tenant, and
          alterations or additions permitted to remain under subparagraph 10B.

     C.   This Paragraph 6 shall not apply in the case of damage or destruction
          by fire or other casualty which is covered by insurance maintained by
          Landlord on the Building (as to which Paragraph 7 shall apply), or
          damage resulting from an eminent domain taking (as to which Paragraph
          14 shall apply).

7.  FIRE OR OTHER CASUALTY

     A.   Tenant shall give prompt written notice to Landlord of any material
          damage caused to the Leased Premises by fire or other casualty as soon
          as reasonably possible after learning of the damage.  If the Leased
          Premises or twenty percent (20%) or more of the floor area of the
          Building are damaged or destroyed by fire or other casualty, then
          Landlord shall have the option to terminate this Lease by giving a
          notice of Lease termination to Tenant within sixty (60) days from the
          date of the damage or destruction.  In the event this Lease is
          terminated by Landlord, Landlord shall refund to Tenant the prepaid
          rend (unaccrued as of the date of damage or destruction), less any sum
          then owing Landlord by Tenant.

     B.   If Landlord has no exercised its option to terminate the Lease, the
          Lease shall continue in full force and effect, and repairs will be
          made by Landlord within a reasonable time thereafter, subject to
          delays arising from shortages of labor or material, acts of God, war
          or other conditions beyond Landlord's reasonable control.  Rent shall
          abate proportionately during Landlord's repair period to the extent
          the Leased Premises are unfit for use by Tenant in the ordinary
          conduct of its business and are not used by Tenant.  Landlord's repair
          obligation shall be limited to Fifteen & 00/100 Dollars ($15.00) per
          square foot of Rentable Area contained within the Leased Premises.
          Landlord shall not be liable to Tenant for

                                      -6-
<PAGE>

          any inconvenience or annoyance to Tenant, or injury to Tenant's
          business resulting from the damage or destruction or any subsequent
          repair work.

     C.   If Landlord does not exercise its option to terminate the Lease, as
          provided in Paragraph 7.A above, but fails to restore the Leased
          Premises to  Building standard condition within one hundred eighty
          (180) days of the date of the damage, subject to extensions for Tenant
          delays, shortages of labor or materials, force majeure or other
          conditions beyond Landlord's reasonable control, Tenant shall have the
          right to terminate the Lease effective immediately upon such written
          notice to Landlord.  If Tenant fails to give such notice within thirty
          (30) days after the expiration of the above-referenced one hundred
          eighty (180) day period (as it may be extended), Tenant shall be
          deemed to have elected not to terminate the Lease.

8.   COMPLIANCE WITH LAWS AND USAGE

     Tenant, at its own expense, will comply with all federal, state, municipal
and other laws, ordinances, rules and regulations applicable to the Leased
Premises (except with respect to pre-existing conditions caused by Landlord) and
the business conducted therein by Tenant (including, without limitation, any
temperature control restrictions); will comply with the Building rules and
regulations attached as Exhibit "C," as such rules and regulations may, from
time to time, be amended by Landlord; and will not commit or permit waste in the
Leased Premises or Building.  Landlord agrees to use diligent good faith efforts
to ensure that the Leased Premises are delivered to Tenant free of any
violations, orders or notices of violations of all public or quasi-public
authorities.  Tenant will not commit any act which is a nuisance or annoyance to
Landlord or to other tenants, or which might, in the exclusive judgment of
Landlord, appreciably damage Landlord's goodwill or reputation, or tend to
injure or depreciate the Project; will not engage in any activity which would
cause Landlord's fire and extended coverage insurance to be canceled or the rate
therefor to be increased (or, at Landlord's option, will pay any such increase);
and will not paint, erect or display any sign, advertisement, placard or
lettering which is visible in the corridors or lobby of the Building or from the
exterior of the Building without Landlord's prior written approval.

9.   LIABILITY AND INDEMNITY

     A.   Tenant shall defend, indemnify and hold Landlord and Landlord's
          designated property management firm and their respective agents,
          employees and affiliated entities (collectively, the "Indemnified
          Party" [or "Indemnified Parties"]) from all losses, claims, suits,
          actions, damages and liability, including costs and expenses of
          defending against the foregoing (collectively, the "Claims"), arising
          or allegedly arising from:  (i) any act or omission of Tenant or
          Tenant's agents, employees, assignees, sublessees, licensees,
          contractors, subcontractors, customers, invitees or other persons from
          time to time in the Leased Premises; (ii)

                                      -7-
<PAGE>

          Tenant's failure (or the failure of Tenant's agents, employees,
          contractors, subtenants, assignees, invitees or other occupants of the
          Leased Premises) to comply fully with all laws and regulations that
          apply to the Leased Premises) to comply fully with al laws and
          regulations that apply to the Leased Premises or the use or occupancy
          of the Leased Premises; (iii) Tenant's breach, violation or
          nonperformance of any covenant of Tenant under this Lease; and (iv)
          any injury to or death of any person or damage to or destruction of
          the property of any person occurring in the Leased Premises. Tenant's
          obligation stated in this subparagraph shall include, without
          limitation, the obligation to defend the Indemnified Parties against
          all Claims where it is asserted, alleged or determined that the acts
          or omissions of an Indemnified Party; but Tenant shall pay all other
          damages.

     B.   Landlord shall defend, indemnify and hold Tenant and Tenant's agents,
          employees and affiliated entities (collectively, the "Indemnified
          Party" [or "Indemnified Parties"]) from all losses, claims, suits,
          actions, damages and liability, including costs and expenses of
          defending against the foregoing (collectively, the "Claims"), arising
          or allegedly arising from any injury to or death of any person or
          damage to or destruction of the property of any person occurring in
          the Building (except for the Leased Premises).  Landlord's obligation
          stated in this subparagraph shall include, without limitation, the
          obligation to defend the Indemnified Parties against all Claims where
          it is asserted, alleged or determined that the acts or omissions of an
          Indemnified Party, whether or not negligent, may have been a cause
          (whether sole, joint or concurrent) of any of such Claims and to pay
          the full cost of any settlement reached by Landlord with respect to
          any such Claims.  Landlord's obligations under this subparagraph will
          not include, however, an obligation to pay that portion of any damages
          the responsibility for which is attributed by a court of competent
          jurisdiction, in a final, nonappealable judgment, to the negligent
          acts or omissions of an Indemnified Party; but Landlord shall pay all
          other damages.

     C.   Landlord and Tenant each hereby release and waive all claims, rights
          of recovery and causes of action that either party (or any party
          claiming by, through or under such party, directly or by subrogation,
          or otherwise) may now or hereafter have against the other party (or
          any of the other party's directors, officers, employees or agents or,
          with respect to Landlord, Landlord's designated property management
          firm) for any loss or damage that may occur to the Project, the Land,
          the Building, the Parking Garage, the Leased Premises, the leasehold
          improvements or any of the contents of any of the foregoing occurring
          by reason of fire or other casualty or resulting from the acts or
          omissions of any other tenant or occupant of the Project (or such
          party's agents, employees, contractors, customers or invitees) or
          resulting from any other cause (including, without limitation, the
          negligence of the waiving party or the negligence of the other party
          or the negligence of either party's directors, officers, employees or
          agents or, with respect to Landlord, Landlord's

                                      -8-
<PAGE>

          designated property management firm) that could have been insured
          against under the terms of (1) a standard fire and extended coverage
          insurance policy, with vandalism and malicious mischief endorsement
          and sprinkler leakage endorsement (where applicable) or all-risk
          insurance policy, or (2) any other loss that is covered by insurance
          of the party suffering the loss. The waiver and release of Landlord
          made by Tenant in this subparagraph will include Landlord's designated
          property management firm. The waiver set forth in this subparagraph
          shall preclude all rights of recovery of third parties by way of
          subrogation, and assignment or otherwise, but shall not apply to any
          deductibles on insurance policies carried by Landlord nor to any co-
          insurance penalty which Landlord might sustain.

     D.   Landlord will maintain in force and effect at all times while this
          Lease is in force and effect such insurance as is required to be
          maintained pursuant to the underlying deeds.

     E.   Tenant will maintain in force and effect at all times during the term
          of this Lease, all risk insurance covering its leasehold improvements
          in excess of Fifteen and 00/100 Dollars ($15.00) per square foot
          Rentable Area contained within the Leased Premises, furniture,
          furnishings and equipment located in the Leased Premises in amounts
          equal to at least eighty percent (80%) of insurable value and public
          liability and property damage insurance with limits of not less than
          One Million Dollars ($1,000,000) for personal injury (including death)
          to any number of persons in any one occurrence and Five Hundred
          Thousand and 00/100 Dollars ($500,000.00) for damage to or destruction
          or property for any one occurrence.  Tenant shall furnish reasonably
          satisfactory evidence to Landlord of maintenance of such insurance
          coverage at any time and from time to time upon request.

10.  ADDITIONS AND FIXTURES

     A.   Tenant shall make no alteration, improvement, repair or replacement to
          the Leased Premises (including, without limitation, any mechanical,
          electrical or plumbing systems located within or serving the Leased
          Premises) without the prior written consent of Landlord.  If
          Landlord's prior written consent is granted, the work shall be
          performed in a good and workmanlike manner at Tenant's expense but by
          workmen of Landlord or by workmen approved in advance in writing by
          Landlord, in accordance with plans and specifications which have been
          previously submitted to, and approved in advance in writing by
          Landlord and subject to the Building rules and regulations.  Landlord
          shall have the right to require certificates of insurance, copies of
          building permits, copies of the final certificate of occupancy,
          executed lien releases and reimbursement of the expenses incurred by
          Landlord in reviewing Tenant's proposed plans and specifications as
          conditions to granting its consent to the performance of such work.
          Landlord's

                                      -9-
<PAGE>

          consent shall also be conditioned upon those furnishing labor or
          materials for Tenant's job working in harmony and not interfering with
          any labor utilized by Landlord or its contractors or by any other
          tenant or other tenant's contractors. If those furnishing labor or
          materials for Tenant's work cause disharmony or interference,
          Landlord's consent may be withdrawn immediately upon notice to Tenant.
          Tenant will not permit any mechanic's or materialmen's lien to be
          placed on the Leased Premises, improvements or Building during the
          Lease term caused by or resulting from any work performed, materials
          furnished or obligation incurred by or at the request of Tenant. In
          the case of the filing of any lien, Tenant shall cause the same to be
          discharged (by bond or otherwise) within twenty (20) days of such
          filing. Any failure to do so within this period will give Landlord the
          right, but not the obligation (among other rights or remedies of
          Landlord), to discharge the same by paying the amount claimed due or
          obtaining the discharge of such lien by deposit in court or bonding.
          Any amounts paid by Landlord, and all reasonable legal fees and
          expenses in defending any such action or the discharge of such lien,
          plus interest thereon from the date of Landlord's written notice to
          Tenant of such payment until Tenant's reimbursement, at the lesser of
          15% per annum or the maximum legally permitted interest rate, shall be
          paid by Tenant to Landlord on demand.

     B.   Tenant may remove its trade fixtures, supplies, movable office
          furniture and equipment not attached to the Building provided: (1)
          removal is made prior to the expiration or termination of this Lease;
          (2) Tenant is not in default of any obligation or covenant under this
          Lease at the time of removal; and (3) Tenant promptly repairs all
          damage caused by removal.  All other property at the Leased Premises
          and any alteration or addition to the Leased Premises (including wall-
          to-wall carpeting, paneling or other wall covering) and any other
          article attached or affixed to the floor, wall or ceiling of the
          Leased Premises shall remain upon and be surrendered with the Leased
          Premises at the expiration or termination of this Lease, Tenant hereby
          waiving all rights to any payment or compensation therefor.  If
          however, Landlord so requests in writing, Tenant will, prior to
          expiration or termination of this Lease, remove any and all
          alterations, additions, fixtures, equipment and property placed or
          installed by it in the Leased Premises (other than the leasehold
          improvements installed prior to the Commencement Date and except to
          the extent Landlord requires such removal in connection with its
          approval of any subsequent alterations, additions or fixtures) and
          will repair any damage caused by such removal.

     C.   If any property not belonging to Landlord remains t the Leased
          Premises after the expiration or termination of the term of this
          Lease, Tenant hereby authorizes Landlord to dispose of the property as
          Landlord may desire without liability to Tenant if the property
          belongs to Tenant.  If the property does not belong to Tenant, Tenant
          agrees to indemnify and hold harmless from all suits, actions,

                                      -10-
<PAGE>

          liability, loss, damages and expenses in connection with any removal,
          exercise of dominion over and/or disposition of such property by
          Landlord.

     D.   Tenant may, at its expense, install additional locks or security
          systems in the Leased Premises provided that (1) such installation
          shall comply with applicable provisions of the Building Rules and
          Regulations attached hereto as Exhibit "C"; (2) Landlord shall be
          furnished with duplicate keys and entry codes to gain entrance where
          permitted under this Lease; and (3) Tenant removes such locks and
          security systems upon the expiration or earlier termination of the
          lease, and repairs all damages and otherwise restores the Leased
          Premises to their condition prior to such installation.

11.  ASSIGNMENT AND SUBLETTING

     A.   Neither Tenant nor Tenant's legal representatives or successors in
          interest by operation of law or otherwise shall assign this Lease or
          sublease the Leased Premises or any part thereof or mortgage, pledge
          or hypothecate its leasehold interest or grant any concession or
          license within the Leased Premises without the prior written
          permission of Landlord.  Provided that there is no Event of Default
          hereunder (or circumstances which, with the passage of time or giving
          of notice, or both, would constitute an Event of Default), Landlord's
          permission shall not be unreasonably withheld or delayed to an
          assignment of this Lease or to a sublease proposed by Tenant.
          However, it is agreed that a withholding or such permission by
          Landlord to a proposed assignment or sublease on the grounds that in
          Landlord's good faith judgment the usage permitted thereunder would
          constitute an "objectionable use" (as defined below), or on the
          grounds that the proposed assignee or sublessee does not have the
          financial net worth reasonably acceptable to Landlord, shall be deemed
          reasonable and shall not be deemed unreasonable.  For purposes hereof,
          the term "objectionable use" shall refer to any use which would (i)
          conflict with the exclusive usage rights granted to any other tenant
          in the Building; (ii) diminish the value or reputation or alter the
          first class character of the Building; (iii) be inconsistent with the
          general use of the Building by other tenants; (iv) be for any other
          use not customarily found in comparable Class A office buildings owned
          by Landlord in the Greenway Plaza area of Houston, Texas, including
          without limitation eleemosynary or governmental or quasi-government
          purposes, a medical or dental practice, an employment office, a school
          or training facility or a religious institution; or (v) materially
          increase the use of the elevators or common areas of the Project or
          the traffic flow of vehicles and/or people in and out of the Building
          or parking garages.  Any attempt to do any of the foregoing without
          the prior written permission of Landlord shall be void.  In the event
          Landlord's permission is requested for an assignment, sublease or
          other transaction, signed copies of all instruments relative thereto
          (executed by all parties except Landlord) shall be submitted to
          Landlord prior to or

                                      -11-
<PAGE>

          contemporaneously with the request for Landlord's written permission
          (it being understood that no such instrument shall be effective
          without the written permission of Landlord). Landlord shall then have
          the right (but no obligation), as of the effective date of the
          requested transaction, to terminate this Lease for the portion of the
          Leased Premises and for that portion of the term of this Lease as to
          which Landlord has been requested to permit such transaction. If
          Landlord elects to terminate this Lease for that portion of the Leased
          Premises and for the portion of the term of this Lease, then the rent
          and other charges payable shall be proportionately reduced. If Tenant
          attempts to permit anyone to occupy any portion of the Leased Premises
          without the prior written permission of Landlord, Landlord shall have
          the right to terminate this Lease effective upon fifteen (15) days
          notice to Tenant at any time thereafter for either the entire Leased
          Premises or only the portion which Tenant has attempted to permit some
          other party to occupy. Should Landlord elect to exercise its
          termination rights, then the rent shall be proportionately reduced. If
          Landlord's permission is granted and the rent payable by the other
          party (or a combination of the rent payable plus any bonus or other
          consideration) exceeds the rent payable under this Lease, then Tenant
          shall pay Landlord fifty percent (50%) of all excess within ten (10)
          days following receipt by Tenant (after deducting all reasonable costs
          directly incurred by Tenant in connection with such assignment or
          sublease, such as tenant improvement costs, moving allowance(s),
          architectural fees, and brokerage commissions, but excluding cash
          inducements or other consideration paid).

     B.   If Tenant is a corporation whose stock is not publicly traded, any
          change in ownership or power to vote a majority of the voting stock in
          Tenant shall constitute an assignment for the purposes of this Lease.
          If Tenant is a partnership having one or more corporations as partner,
          the provisions of the preceding sentence shall apply to each
          corporation as if it alone had been the Tenant.  If Tenant is a
          partnership (whether or not having any corporation as general
          partner), the transfer of a partnership interest constituting a
          majority shall constitute an assignment for the purposes of this
          Lease.

          Notwithstanding any other provision of this Lease to the contrary, the
          prohibition on assignments shall not be applicable (and no prior
          consent of or notice to Landlord shall be required) with respect to
          (i) a merger between Tenant and another entity or (ii a transfer of a
          controlling interest of stock in Tenant, provided the surviving entity
          (in the case of a merger) or Tenant (in the case of a transfer in
          control) has a net worth greater than or equal to the net worth of
          Tenant immediately prior to such merger or transfer of control  Upon
          written request from Landlord, Tenant shall furnish evidence that a
          particular assignment complies with the provisions of the preceding
          sentence.

                                      -12-
<PAGE>

     C.   If Landlord gives written permission to a particular assignment,
          sublease or other transaction, it shall not be deemed as permission to
          any other or subsequent transaction or a release of Tenant from its
          covenants, duties and obligations under this Lease.  If this Lease is
          assigned or if the Leased Premises are subleased (whether in whole or
          in part) or in the event of the mortgage, pledge or hypothecation of
          the leasehold interest or grant of any concession or license within
          the Leased Premises without the prior written permission of Landlord,
          or if the Leased Premises are occupied in whole or in part by anyone
          other than Tenant without the prior written permission of Landlord,
          Landlord may nevertheless collect rent from the occupant and apply the
          net amount collected to the rent payable hereunder, but no collection
          of rent by Landlord shall be deemed a waiver of these provisions or a
          release of Tenant from the further performance of its covenants,
          duties and obligations hereunder.

     D.   Notwithstanding the foregoing provisions of this Paragraph 11, Tenant
          shall have the right at any time and from time to time, as many times
          as may be convenient, to sublet or assign all or part of the Leased
          Premises to an "Affiliate" of Tenant (as defined below); provided,
          however, that (i) Tenant shall nonetheless give Landlord written
          notice of such transfer together with a fully-executed copy of the
          transfer instrument and such other supporting documentation as
          Landlord may reasonably request, (ii) the undersigned Tenant will
          nevertheless remain directly and primarily liable for the performance
          of all of the covenants, duties and obligations of Tenant hereunder
          (including, without limitation, the obligation to pay all rent and
          other sums herein provided to be paid); and (iii) Landlord shall be
          permitted to enforce the provision of this instrument against the
          undersigned Tenant and/or any assignee without demand upon or
          proceeding in any way against any other person.  As used herein, the
          term "Affiliate" shall mean any person or entity controlling,
          controlled by, or under common control with another such person or
          entity.  "Control" as used herein shall mean the possession, direct or
          indirect, of the power to direct or cause the direction of the
          management and policies of such controlled person or entity;
          ownership, directly or indirectly, of more than fifty percent (50%) of
          the voting securities of, or possession of the right to vote, in the
          ordinary direction of its affairs, more than fifty percent (50%) of
          the voting interest in any person or entity shall be presumed to
          constitute such control.

12.  SUBORDINATION

     Tenant accepts this Lease subject to all matters of record which affect the
Building and subject and subordinate to any mortgage or deed of trust, presently
existing or hereafter placed upon the Project, and to any renewals,
modifications and extensions thereof.  Tenant agrees that any such mortgagee
and/or beneficiary of any deed of trust ("Landlord's Mortgagee") shall have the
right at any time to subordinate such mortgage or deed of trust to this Lease,
on terms and conditions Landlord's Mortgagee may deem appropriate in its sole
discretion.  Tenant agrees to

                                      -13-
<PAGE>

execute such instruments subordinating this Lease as Landlord or Landlord's
Mortgagee may request, upon demand, provided such instruments are in form and
substance customary in the industry for comparable transactions.

13.  OPERATING COST

     A.   If, after the calendar year 1996 ("Base Year"), the Project Operating
          Cost (as defined below) increases, then Tenant agrees to pay to
          Landlord, as additional rent, its pro rata share of increases in the
          Project Operating Cost over and above the amount of the Project
          Operating Cost attributable to the Base Year.  Tenant's pro rata share
          of such increases shall be a fraction of the total increases, the
          numerator of which shall be the Rentable Area of the Leased Premises,
          and the denominator of which shall be the total Rentable Area of the
          Building.

     B.   "Project Operating Cost" shall consist of the operating expenses of
          the Project, reasonably allocable to the Building and Parking Garage,
          computed on the accrual basis and determined in accordance with
          generally accepted accounting principles which shall be consistently
          applied.  The term "operating expenses" shall mean all expenses, costs
          and disbursements (but not costs of replacement of capital investment
          items, nor specific costs especially billed to and paid by specific
          tenants, nor rental [line missing] to pay because of, or in connection
          with, the ownership, management, maintenance, repair and operation of
          the Project, including, but not limited to, the following:

          (1)  Wages and salaries of all workers and employees engaged in the
               direct operation and maintenance of the Project, including taxes,
               insurance and benefits relating thereto;

          (2)  Management fees relating to the direct operation and management
               of the Project;

          (3)  Costs of all supplies and materials used in direct operation,
               maintenance and repair of the Project;

          (4)  Cost of water and power, heating, lighting, air conditioning and
               ventilating for the Project;

          (5)  Cost of all maintenance and service agreements relating to the
               Project and all equipment therefor (including, without
               limitation, janitorial service, window cleaning and elevator
               maintenance);

          (6)  Cost of casualty and liability insurance applicable to the
               Project and Landlord's personal property used in connection
               therewith;

                                      -14-
<PAGE>

          (7)  All federal, state, county or municipal taxes, assessments and
               other governmental charges, whether by existing taxing
               authorities or by others subsequently created, and any other
               taxes and improvement assessments attributable to that portion of
               the Land allocated to the Building, the Building and the Parking
               Garage or their operation (excluding federal and state income
               taxes).  Tenant will be responsible for ad valorem taxes on its
               personal property and on the value of leasehold improvements to
               the extent they are separately assessed by any taxing authority;

          (8)  Cost of repairs and general maintenance (excluding costs of
               repairs paid by proceeds of insurance or by Tenant or other third
               parties, and alterations attributable solely to tenants of the
               Project other than Tenant), including the cost of inspections and
               renovations required by governmental authority;

          (9)  Amortization of the cost of capital investment items and their
               installation which are primarily for the purposes of safety,
               saving energy or reducing operating costs or which may be
               required by governmental authority.  All such costs shall be
               amortized over the reasonable life of the capital investment
               items, with the reasonable life and amortization schedule being
               determined in accordance with generally accepted accounting
               principles.

     C.   Tenant shall be obligated to discharge its payment obligation with
          respect to increases in the Project Operating Cost in accordance with
          the billing procedures used by Landlord.  Landlord shall have the
          right to invoice Tenant for such increases periodically, as Landlord
          may desire, but not less frequently than annually; and Landlord may
          alter its billing procedures at any time during the Lease term.
          Landlord may (but shall have no obligation to) submit a statement or
          invoice to Tenant for each month of the Lease term for one-twelfth
          (1/12th) of Tenant's pro rata share of Project Operating Cost
          increases, and Tenant shall pay the indicated amount contemporaneously
          with Base Rental.  The monthly one-twelfth (1/12th) amount stated in
          Landlord's monthly statement or invoice shall be Landlord's estimate
          of Tenant's monthly pro rata share of Project Operating Cost
          increases, and shall be based on the actual Project Operating Cost
          incurred during the prior calendar year and Landlord's good faith
          business judgment of the estimated Project Operating Cost for the then
          current year.  Landlord reserves the right to adjust the estimate of
          the Project Operating Cost at any time during the then current year if
          the actual Project Operating Cost then being incurred varies from
          Landlord's prior estimate.

          Each calendar year Landlord shall perform computations necessary to
          determine the amount of increases in the Project Operating Cost
          properly payable by Tenant.   If Tenant has overpaid pursuant to
          Landlord's periodic billing of such increases,

                                      -15-
<PAGE>

          then Landlord shall credit Tenant's account for the amount of the
          excess; but, if Tenant shall have underpaid pursuant to Landlord's
          periodic billing of such increases, then Landlord shall ill Tenant for
          the amount of the underpayment (which underpayment shall be due within
          thirty (30) days following such billing). Tenant's pro rata share of
          such increases in the Project Operating Cost for partial calendar
          years and for partial months of the Lease term occurring at the
          beginning or end of the Lease term shall be [line missing] as to
          reduce the monthly installments of Base Rental payable by Tenant
          hereunder below the amount set forth in Paragraph 3 of this Lease.

     D.   Notwithstanding the foregoing provisions of this Paragraph 13, the
          Project Operating Cost for the Base Year shall be equal to actual
          operating costs for that calendar year, with those Project Operating
          Costs that vary with occupancy being adjusted upward to reflect the
          costs of operating the Project at a Building occupancy level of 95%;
          however, if the occupancy level of the Building for the Base Year
          equals or exceeds 95%, there shall be no upward adjustment.  Likewise,
          the Project Operating Cost for subsequent calendar years shall be
          adjusted upward to reflect a 95% Building occupancy level; however, if
          the occupancy level of the Building for any calendar year after the
          Base Year equals or exceeds 95%, there shall be no such upward
          adjustment and actual costs shall be used to determine the Project
          Operating Cost for such year.

     E.   Within sixty (60) days from the rendition of any such statement,
          Tenant may question the amount and propriety of any item appearing or
          excluded therefrom.  Landlord agrees that, for a period of two (2)
          years following expiration of the applicable calendar year, it will
          maintain complete and accurate records of all costs and expenses which
          shall be paid or incurred by it in connection with the operation of
          the Project.  Tenant, at its expense, shall have the right at all
          reasonable times to audit Landlord's books and records relating to
          this Lease for any year for which additional rental payments become
          due, insofar as such books and records pertain to costs involved in
          rent escalation.  Any overpayment by Tenant shall be credited to its
          account.

14.  EMINENT DOMAIN

     A.   If any material part of the Project is taken by eminent domain or
          voluntarily conveyed to the condemning authorities in settlement of an
          eminent domain action, Landlord shall have the option to terminate
          this Lease by giving a notice of Lease termination to Tenant within
          sixty (60) days from the date of the taking.  It is further agreed
          that Tenant shall have the right to terminate this Lease if all or a
          portion of the Leased Premises is so taken and the remainder of the
          Leased Premises is insufficient for the conduct of Tenant's business.
          If Tenant so elects to terminate this Lease, it shall notify Landlord
          within thirty (30) days after the

                                      -16-
<PAGE>

          date of taking; otherwise, Tenant shall be deemed to have elected not
          to terminate this Lease. If this Lease should be terminated under this
          Paragraph 14, rental shall be payable up to the date that possession
          is taken by the condemning authority; and Landlord will refund to
          Tenant any prepaid unaccrued rent, less any sum then owing by Tenant
          to Landlord.

     B.   If the Lease is not terminated, and the taking involved a portion of
          the Leased Premises, rental shall be reduced in proportion to the area
          of the Leased Premises taken and Landlord shall repair any damage to
          the remainder of the Leased Premises resulting from such taking or any
          taking which impacts Tenant's use of the Parking Garage or the common
          areas of the Building.  Landlord's repair obligation in such
          circumstance swill be limited to the performance of construction work
          necessary to return the damaged portion of the remaining Leased
          Premises to the condition in which such portion was placed by
          Landlord, at Landlord's expense, on or before the Commencement Date.

     C.   All sums awarded or agreed upon between Landlord and the condemning
          authority for the taking of the interest of Landlord or Tenant,
          whether as damages or as compensation, will be the property of
          Landlord without prejudice, however, to claims of Tenant against the
          condemning authority for the unamortized cost of leasehold
          improvements which were paid for by Tenant and taken by the condemning
          authority.

15.  ACCESS BY LANDLORD

     Landlord, Landlord's Mortgagee, their agents and employees shall have
access to and the right to enter upon the Leased Premises at any reasonable time
after prior notice (except in an emergency) to examine its condition, to make
any repairs or alterations required to be made by Landlord, to show the Leased
Premises to prospective purchasers or tenants and for any other purpose deemed
reasonable by Landlord.

16.  LANDLORD'S LIEN

     Tenant, as debtor, hereby grants to Landlord, as secured party, a contract
lien and security interest on all fixtures, furniture, equipment, merchandise,
inventory and other property of Tenant (including Tenant's ownership interests,
interests as lessee and options to purchase any of such property) presently
situated at or hereafter placed in the Leased Premises, and upon all proceeds of
any insurance which may accrue to Tenant by reason of destruction or damage to
any such property, as [line missing] and the performance of all other
obligations of Tenant under this Lease. All exemption laws are hereby waived in
favor of such lien and security interest and in favor of Landlord's statutory
lien.  This contract lien and security interest may be foreclosed with or
without court proceedings by public or private sale or any other lawful method,
provided that Landlord gives Tenant at least ten (10) days notice of the time
and place of said sale; and

                                      -17-
<PAGE>

Landlord shall have the right to become the purchaser, upon being the highest
bidder at such sale. A carbon copy, photographic or other reproduction of this
Lease is sufficient as a financing statement. If any of the obligations of
Tenant under this Lease are guaranteed pursuant to a guaranty instrument, Tenant
hereby consents and agrees to al of the terms and provisions of such guaranty.
Landlord agrees to subordinate its lien rights to a third party providing
furniture, fixtures and/or equipment to Tenant or providing funds for the
acquisition of same, which subordination shall be in writing, signed by all
parties, and in a form reasonably acceptable to landlord.

17.  EVENTS OF DEFAULT

     A.   Each of the following acts or omissions of Tenant or occurrence shall
          constitute an "Event of Default":

          (1)  Failure or refusal by Tenant to timely pay rent within five (5)
               days of the due date;

          (2)  Failure to perform or observe any other covenant or condition of
               this Lease within thirty (30) days following written notice from
               Landlord of such failure or such longer period as is reasonably
               necessary to cure such failure, provided that Tenant shall
               commence the cure of said failure within such thirty (30) day
               period and shall continuously and diligently pursue the remedy of
               such failure; or

          (3)  Abandonment or vacating of the Leased Premises or any significant
               portion thereof while failing to pay Base Rental and other
               payments due hereunder when due.  Although Tenant continues to
               pay rent, if Tenant abandons or vacates fifty percent (50%) or
               more of the Leased Premises, Landlord shall have the right to
               recapture the Leased Premises, in which event, Tenant shall
               thereafter be relieved of its covenants, duties and obligations
               under this Lease.

     B.   Upon any Event of Default, Landlord may, at its option, in addition to
          all other rights and remedies given hereunder or by law or equity, do
          any one or more of the following:

          (1)  Terminate this Lease, in which event Tenant shall immediately
               surrender possession of the Leased Premises to Landlord;

          (2)  Enter upon and take possession of the Leased Premises,
               terminating Tenant's right to possession of the Leased Premises,
               and expel or remove Tenant and any other occupant therefrom, with
               or without having terminated the Lease;

          (3)  Alter locks and other security devices at the Leased Premises,
               remove Tenant's property and the property of other located within
               the Leased Premises, and cease providing services.  The
               provisions of this Paragraph 17 will override and control any
               conflicting provisions of Section 93.002 of the Texas Property
               Code, as well as any successor statute governing the right of a
               landlord to change the door locks of a tenant under a commercial
               lease.

     C.   Exercise by Landlord of any one or more remedies granted under this
          Lease or otherwise available shall not be deemed to constitute
          Landlord's acceptance of surrender of the Leased Premises by Tenant,
          whether by agreement or by operation of law.  Such surrender can be
          effected only by the written agreement of Landlord and Tenant
          hereafter entered into.  Tenant acknowledges that if Landlord has
          altered locks and other security devices at the Leased Premises after
          an Event of Default, Landlord may require full payment of all sums
          then due to Landlord under this Lease as a condition to Tenant's
          entitlement to a key to new or altered locks that Landlord may have
          placed on the Leased Premises after an Event of Default.  After any
          Event of Default, Landlord's alteration of locks and security devices
          and exercise of control over the property of Tenant or others at the
          Leased Premises shall not be deemed unauthorized or constitute a
          conversion.  All claims for damages by reason of reentry, repossession
          and/or alteration of locks or other security devices are hereby
          waived, as are all claims for damages by reason of any distress
          warrant, forcible detainer proceedings, sequestration proceedings or
          other legal process.  Tenant agrees that any reenty by Landlord may be
          pursuant to judgment obtained in forcible detainer proceedings or
          other legal proceedings or without the necessity for legal
          proceedings, as Landlord may elect, and Landlord shall not be liable
          in trespass or otherwise.

     D.   If Landlord elects to terminate the Lease for an Event of Default,
          then, despite such termination, Tenant shall be liable for and shall
          pay to Landlord the sum of (x) all rent and other indebtedness accrued
          to the date of termination, plus (y) as damages, an amount equal to
          the present value (computed as of the date of any such termination
          using a discount factor equal to 9% per annum) of the difference
          between the amount stated in clause (i), below, and the amount stated
          in clause (ii) below, as follows:

          (i)  the total Base Rental, plus Tenant's share of Project Operating
               Cost increases (using such sum for the year of such termination
               as the basis for determining the amount thereof which would have
               been due each year thereafter for the remainder of the Lease term
               had it not been terminated), for the remaining portion of the
               Lease term if such term had not been terminated by Landlord prior
               to the Expiration Date stated in Paragraph 2; and

                                      -19-
<PAGE>

          (ii) the fair market rental value of the Leased Premises, computed as
               of the date of such termination, for the remaining portion of the
               Lease term if such term had not been terminated by Landlord prior
               to the Expiration Date stated in Paragraph 2.

          If Landlord elects to terminate the Lease for an Event of Default, in
          lieu of exercising the rights of Landlord under the preceding portion
          of this subparagraph D, or if Landlord elects to terminate Tenant's
          right to possession of the Leased Premises without terminating the
          Lease, then Landlord may instead hold Tenant liable for (x) all rent
          and other indebtedness accrued to the date of Lease termination or the
          date on which Tenant's possession is terminated, as the case may be,
          plus (y) such Base Rental and Tenant's share of Project Operating Cost
          increases (using such sum for the year of such termination as the
          basis for determining the amount thereof which would have been due
          each year thereafter for the remainder of the Lease term) as would
          otherwise have been required to be paid by Tenant to Landlord during
          the period following the termination of the Lease or Tenant's right to
          possession of the Leased Premises to the date of expiration of the
          Lease term stated in Paragraph 2, diminished by any net sums
          thereafter received by Landlord through reletting the Leased Premises
          during said period (after deducting expenses incurred by Landlord as
          provided in subparagraph E).  Reentry by Landlord will not affect the
          obligations of Tenant for the unexpired Lease term.  Actions to
          collect amounts due by Tenant may be brought from time to time by
          Landlord during the aforesaid period, on one or more occasions,
          without the necessity of Landlord waiting until expiration of such
          period.  Tenant shall not be entitled to any sums obtained by
          reletting in excess of the Base Rental provided for in this Lease.

     E.   In case of an Event of Default, Tenant shall also be liable for and
          shall pay to Landlord: broker's fees incurred by Landlord in
          connection with reletting the whole or any part of the Leased
          Premises; the cost of removing and storing Tenant's or other
          occupant's property; the cost of repairing, altering, remodeling or
          otherwise putting the Leased Premises into condition acceptable to a
          new tenant or tenants; and all other reasonable expenses (including
          attorney's fees and court costs) incurred by Landlord in enforcing
          Landlord's remedies.  Actions to collect amounts due by Tenant may be
          brought from time to time by Landlord without the necessity of
          Landlord waiting until expiration of the Lease term.

     F.   Past-due rent and other past-due sums payable by Tenant under this
          Lease shall bear interest form the date due until paid at the lesser
          of fifteen percent (15%) per annum or the maximum nonusurious interest
          rate permitted by law.

     G.   In the event of termination of the Lease or termination of Tenant's
          right to possession of the Leased Premises or repossession of the
          Leased Premises for an

                                      -20-
<PAGE>

          Event of Default, Landlord shall make reasonable efforts to relet the
          Leased Premises, or portions thereof, and to collect rental after
          reletting; and in the event of reletting, Landlord may relet the whole
          or any portion of the Leased Premises for any period, to any tenant,
          and for any use and purpose; provided, however, that Landlord shall
          have no obligation to relet Tenant's space in preference to other
          space which Landlord has available for lease in the building. Tenant
          hereby waives and released Landlord from any obligation that may be
          otherwise imposed by law which would obligate Landlord to relet the
          Leased Premises or attempt to relet the Leased Premises after an Event
          of Default. If Landlord, in its sole discretion, elects to relet it,
          it can relet the whole or any portion of the Leased Premises for any
          period, to any tenant, and for any use.

     H.   If Tenant fails to make any payment, perform any obligation or cure
          any default hereunder within the time permitted, Landlord, without
          being under any obligation to do so and without thereby waiving such
          failure or default, may make the payment, [line missing] enter the
          Leased Premises for such purpose).  Tenant agrees to pay Landlord,
          upon demand, all costs, expenses and disbursements (including
          reasonable attorney's fees) incurred by Landlord in taking such
          remedial action.

     I.   In the event of any default by Landlord, Tenant's exclusive remedy
          shall be an action for damages (Tenant hereby waiving the benefit of
          any laws granting it a pre-judgment lien upon the property of Landlord
          and/or upon rent due Landlord)' but, prior to any such action, Tenant
          will give Landlord and Landlord's Mortgagee, as provided in Paragraph
          21 below, written notice specifying such default with particularity;
          and Landlord shall have a reasonable period (but not less than thirty
          (30) days, plus such additional period, as may be required in the
          exercise of reasonable diligence) in which to commence to cure any
          such default.  Unless and until Landlord fails to commence to cure any
          default after notice (or, having so commenced, thereafter fails to
          exercise reasonable diligence), Tenant shall not have any remedy or
          cause of action by reason thereof.  All obligations of Landlord
          hereunder will be construed as covenants, not conditions; and all
          obligations will be binding upon Landlord only during the period of
          its ownership of the Building and not thereafter.

     J.   In connection with either party instituting action seeking judicial
          relief at law or in equity in connection with this Lease, the
          prevailing party shall be entitled to reasonable attorney's fees and
          court costs.

18.  NONWAIVER

     Neither acceptance of rent by Landlord nor failure by Landlord to complain
of any default of Tenant shall constitute a waiver of any of Landlord's rights
hereunder.  Waiver by Landlord of

                                      -21-
<PAGE>

any right for any default of Tenant shall not constitute a waiver of any right
for either a subsequent default of the same obligation or any other default.

19.  HOLDING OVER

     If Tenant remains in possession of the Leased Premises after the expiration
of the term of this Lease without Landlord and Tenant executing a new lease,
then Tenant shall be deemed to be occupying the Leased Premises as a tenant-at-
sufferance, subject to all the covenants and obligations of this Lease
(including, without limitation, the provisions of Paragraph 13 relating to the
Project Operating Cost), but at a daily base rental rate equal to the greater of
(x) the prevailing Building base rental rate, as reflected in Landlord's
published rent schedule then in effect, or (y) 150% of the per diem Base Rental
provided hereunder, computed on the basis of a thirty (30)-day month.
Notwithstanding provisions to the contrary applicable during the original term
or any extension term of this Lease, Landlord shall have the right to terminate
the tenancy-at-sufferance immediately upon deliver of notice to Tenant.  The
provisions of this paragraph will not preclude Landlord from recovering from
Tenant all damages suffered by Landlord as a consequence of Tenant's holdover in
the Leased Premises.

20.  NOTICE

     Any notice which may or shall be given under the terms of this Lease shall
be in writing and shall be either delivered by hand or sent by United States
Certified Mail, Return Receipt Requested, postage prepaid, or by Federal Express
or other expedited courier service where proof of delivery can be obtained, as
follows:  if for Landlord, to the Building office; and if for Tenant, to the
Leased Premises.  Such addresses may be changed from time to time by either
party by giving notice as provided above.  Notice shall be deemed given when
delivered (if delivered by hand) or when postmarked (if sent by mail).  Despite
the foregoing, notice given to Tenant by hand will be effectively given wherever
the intended recipient is found and will be deemed received upon the date of
actual receipt.

21.  LANDLORD'S MORTGAGEE

     At any time the Building is subject to a mortgage and/or deed of trust, and
Tenant gives notice to Landlord alleging default by Landlord, Tenant will also
simultaneously give a coy of such notice to each Landlord's Mortgagee (provided
Landlord or Landlord's Mortgagee shall have advised Tenant in writing of the
name and address of Landlord's Mortgagee) and each Landlord's Mortgagee shall
have the right (but no obligation) to cure such default during the period that
is permitted to Landlord, plus an additional period of thirty (30) days.  Tenant
will accept curative action (if any) taken by Landlord's Mortgagee with the same
effect as if such action had been taken by Landlord.  Tenant will, at such time
or times as Landlord, may request, sign a certificate stating whether this Lease
is in full force and effect; whether any amendments or modifications exist;
whether, to Tenant'' knowledge, there are any defaults hereunder; and such other
information and agreements as may be reasonably requested.

22.  CONDITION OF PREMISES

          sum not to exceed Fifteen & 00/100 Dollars ($15.00) per square foot of
          Rentable Area (the "Construction Allowance") toward the cost of

          drawings for all leasehold improvements, including mechanical,
          electrical and plumbing (MEP) drawings to be prepared by Landlord's
          designated engineering firm.  Any costs in excess of the above amount
          shall be borne by Tenant.

23.  MOVING ALLOWANCE

     Landlord shall contribute up to One & 50/100 Dollars ($1.50) per square
foot of Rentable Area toward the moving costs incurred by Tenant, including,
without limitation, the costs of relocating Tenant's furniture, equipment and

days after occupancy and receipt of an invoice from Tenant.

24.  PARKING

     A.   For each 1,000 square feet of Rentable Area leased and occupied in the
          Leased Premises, Landlord shall make available to Tenant up to three
          and one-half (3.5) unreserved parking permits in the Parking Garage in
          areas designated by Landlord, which shall be equally prorated through
          the Parking Garage unless otherwise directed by Landlord.  Landlord
          shall use good faith, reasonable efforts (subject to availability), to
          provide up to an additional one-half (0.5) unreserved parking permit
          per each 1,000 square feet of Rentable Area ("Additional Permits")
          leased and occupied on a month-to-month basis with Landlord retaining
          the right to recapture said Additional Permits upon thirty (30) days
          prior written notice.  Such Additional Permits may, at Landlord's
          election, be located in the Parking Garage, the One Greenway Garage,
          the Greenway East Garage, the Houston City Club Garage, the North
          Richmond Garage or in other garages or parking areas (within one (1)
          mile of the Project) Landlord may contract for Tenant's use.  During
          the initial term of the Lease, the charge for said parking permits
          shall be $16.50 per permit per month, plus state and local taxes.
          During

                                      -23-
<PAGE>

          the Renewal Period, the charge for said parking permits shall be at
          the then prevailing "market" rate, plus state and local taxes.

     B.   Landlord shall provide for a Tenant validation system for visitor
          parking.  All charges incurred during the first two (2) hours per
          visitor shall be free.  Tenant shall be liable for any additional
          charges incurred.

     C.   The driver of each car shall have so-called "in-and-out" privileges.
          Landlord shall not be responsible for any loss or damage to any car or
          property therein or for personal injury or death occurring in the
          parking area or garage, except to the extent caused solely by its own
          negligence or that of its own agents or employees in the scope of
          their employment.

25.  EXPANSION OPTION

     A.   Provided no uncured Event of Default has occurred under this Lease,
          Tenant shall have the option (the "Expansion Option") to lease
          approximately 4,386 square feet of Rentable Area (+/- 20%), on the
          sixth (6th) floor of the Building, as outlined and hatched on Exhibit
          "B" attached (the "Expansion Space"), at the "Fair Market Rental Rate"
          (as hereinafter defined).  In order to exercise such Expansion Option,
          Tenant shall be required to give Landlord written notice thereof
          ("Expansion Notice") no earlier than September 1, 1997 nor later than
          October 31, 1997.  However, Landlord shall have the option to tender
          possession of the Expansion Space to Tenant on any date between
          January 1 and August 31, 1998.

     B.   In the event Tenant leases space under this Paragraph 25, Tenant's
          Cancellation Option(s) as provided in Paragraph 28.A and Paragraph
          28.B shall be adjusted to take into consideration the increased Base
          Rental and amortization of Contributions provided by Landlord, if any,
          for the Expansion Space.

26.  PREFERENTIAL RIGHT TO LEASE

     A.   First Preferential Right to Lease Space

          (1)  Tenant shall have a Preferential Right to Lease approximately
               2,482 square feet of Rentable Area (+/- 20%) contiguous to the
               Leased Premises on the sixth (6th) floor of the Building (the
               "First Preferential Space"), as outlined and hatched on Exhibit
               "B" attached, which becomes available for direct lease to a new
               tenant (whether or not a bona fide offer has been made) prior to
               November 1, 1988; provided that (i) no Event of Default has
               occurred and is continuing, and (ii) Tenant remains in occupancy
               of the entire Leased Premises.

                                      -24-
<PAGE>

          (2)  At any time after the First Preferential Space becomes available,
               as provided above, but prior to leasing such space to a new
               tenant, Landlord shall first offer such space in writing to
               Tenant. Such offer notice shall specify the amount and location
               of such space, the date of availability, and shall be leased
               pursuant to the following provisions:

               (a)  The rental rate for the First Preferential Space shall be
                    the rental rate then in effect for the Leased Premises
                    (subject to increased and at such times as provided in
                    Paragraph 3 herein); and

               (b)  Landlord shall contribute a construction and architectural
                    allowance based upon the number of months remaining in the
                    initial term of the Lease from the commencement date of the
                    First Preferential Space multiplied by eighteen cents
                    ($0.18).

          (3)  Any First Preferential Space shall be leased for the period
               commencing upon the earlier of Tenant's possession of the First
               Preferential Space or the date of availability specified in
               Landlord's offer and expiring upn the last day of the term of the
               Lease, including the Renewal Period, if exercised. Rent shall
               commence on the earlier of (i) occupancy of the First
               Preferential Space by Tenant; (ii) Substantial Completion of the
               First Preferential Space; or (iii) forty-five (45) days from
               tender of possession of the First Preferential Space. Tenant
               shall have five (5) working days from receipt within which to
               accept or reject such offer. If Tenant rejects such offer or
               fails to accept such offer within the foregoing five (5) working
               day period, this First Preferential Right to Lease shall be
               deemed waived by Tenant for ninety (90) days during which time
               Landlord may lease all or a portion of the First Preferential
               Space. If a lease with another tenant(s) is not executed within
               said ninety (90) days period following Tenant's rejection or
               failure to notify period as provided above, then Tenant's
               Preferential Right to Lease with respect to such space shall be
               reinstated in full force and effect.

          (4)  If Tenant accepts Landlord's offer, Tenant shall, no later than
               twenty (20) days after Landlord's submission of such offer,
               execute an amendment of the Lease adding the First Preferential
               Space to the Leased Premises on the terms specified in Paragraph
               26.A(2), above.

          (5)  In the event Tenant leases space under this Paragraph 26.A,
               Tenant's Cancellation Option(s) as provided in Paragraph 28.A and
               Paragraph 28.B shall be adjusted to take into consideration the
               increased Based Rental and amortization of Contributions provided
               by Landlord, if any, for the First Preferential Space.

                                      -25-

     B.   Second Preferential Right to Lease Space

          (1)  In the event Tenant has leased all space pursuant to its First
               Preferential Right to Lease Space hereinabove, Tenant shall have
               a Second Preferential Right to Lease approximately 5,616 square
               feet of Rentable Area (+/- 20%) contiguous to the Leased Premises
               on the sixth (6th) floor of the Building (the "Second
               Preferential Space"), as outlined and hatched on Exhibit "B"
               attached, which becomes available for direct lease to a new
               tenant (whether or not a bona fide offer has been made) prior to
               November 1, 1999; provided that (i) no Event of Default has
               occurred and is continuing; and (ii) Tenant remains in occupancy
               of the entire Leased Premises.

          (2)  At any time after the Second Preferential Space becomes
               available, as provided above, but prior to leasing such space to
               a new tenant, Landlord shall first offer such space in writing to
               Tenant.  Such offer notice shall specify the amount and location
               of such space, the date of availability and the Fair Market
               Rental Rate for such space.  Any Second Preferential Space shall
               be leased for the period commencing upon the earlier of Tenant's
               possession of the Second Preferential Space or the date of
               availability specified in Landlord's offer and shall be leased
               for a minimum of sixty (60) months from the commencement date of
               the Second Preferential Space.  Rent shall commence on the

               Tenant; (ii) Substantial Completion of the Second Preferential
               Space or (iii) forty-five (45) days from tender of possession of
               the Second Preferential Space.  Tenant shall have five (5)
               working days from receipt within which to accept or reject such
               offer.  If Tenant rejects such offer or fails to accept such
               offer within the foregoing five (5) working day period, this
               Second Preferential Right to Lease shall be deemed waived by
               Tenant for ninety (90) days during which time Landlord may lease
               all or a potion of the Second Preferential Space.  If a lease
               with another tenant(s) is not executed within said ninety (90)
               day period following Tenant's rejection or failure to notify
               period as provided above, then Tenant's Second Preferential Right
               to Lease with respect to such space shall be reinstated in full
               force and effect.

          (3)  If Tenant accepts Landlord's offer, Tenant shall, no later than
               twenty (20) days after Landlord's submission of such offer,
               execute an amendment of the Lease adding to the Second
               Preferential Space to the Leased Premises on the terms specified
               in Landlord's offer and extending the term (if necessary) of the
               Lease for the entire Leased Premises by the number of months to
               be coterminous with the Second Preferential Space term specified
               above.  The Base Rental for the Leased Premises shall continue

                                      -26-
<PAGE>

               during the remainder of the original term of the Lease at the
               rate(s) in effect under this Lease; thereafter, the rental rate
               for such space shall be at the Fair Market Rental Rate then in
               effect.

          (4)  In the event Tenant leases space under this Paragraph 26.B,
               Tenant's Cancellation Option(s) as provided in Paragraph 28.A and
               Paragraph 28.B shall be adjusted to take into consideration the
               increased Base Rental and amortization of Contributions provided
               by Landlord, if any, for the Second Preferential Space.

               Landlord given at anytime prior to the end of the forty-second
               (42nd) full calendar month following the commencement of Tenant's
               Lease and occupancy of the original Leased Premises, the
               Expansion Space, the First Preferential Space, and the Second
               Preferential Space, as applicable, Tenant shall have the right to
               cancel this Lease with respect to all or a portion of the Leased
               Premises located on the sixth (6th) floor of the Building,
               subject to Tenant's payment of Stipulated Damages calculated
               pursuant to Subparagraph 28.A(2) below and the conditions in
               Subparagraph 28.A(3).

               of this Paragraph 28.A or Tenant's cancellation rights shall be
               null and void.  If Tenant exercises its First Cancellation Option
               pursuant to this Paragraph 28.A, Tenant shall pay Landlord, as
               "Stipulated Damages", the sum of the following:

               (a)  The unamortized portion of Landlord's contributions, rental
                    abatement, moving allowance, and any other reimbursement
                    (collectively "Contributions") applicable to the Leased
                    Premises.  Any costs associated with asbestos abatement in
                    the Leased Premises shall not be included in Contributions.
                    For purposes of calculating Stipulated Damages,
                    Contributions shall be treated as if such were a loan, fully
                    amortized over the original term of the Lease at twelve
                    percent (12%) annual interest, compounded monthly.
                    Stipulated Damages as outlined herein are subject to
                    adjustment for any Expansion Space and/or Preferential Right
                    Space leased by Tenant pursuant to Paragraph 25 and

<PAGE>

                    Space shall begin upon the commencement date of the
                    respective additional space leased; plus

               (b)  An amount equal to three (3) month's Base Rental based on
                    the Base Rental being paid by Tenant at the time of said
                    cancellation.

          (3)  Tenant's First Cancellation Option shall be subject to the
               condition that (i) an Event of Default shall not have occurred
               and is continuing at the time of exercise, (ii) Tenant is in
               occupancy of the entire Leased Premises prior to Tenant's written
               notice, (iii) Landlord is unable to accommodate Tenant's growth
               by providing additional premises containing no less than fifty
               percent (50%) of the then current Rentable Area of the Leased
               Premises in one (1) contiguous space to be located in either One,
               Two, Eight or Twelve Greenway Plaza or 8800 Buffalo Speedway;
               (iv) Tenant has leased and occupied the original Leased Premises,
               the Expansion Space, the First Preferential Space and the Second
               Preferential Space, in accordance with this Lease; and (v) Tenant
               has leased and occupied that portion of the leased Premises being
               cancelled for a minimum of forty-two (42) months.  Therefore the
               Lease and/or any amendment(s) thereto may be terminated
               separately depending on the commencement date of the original
               Leased Premises, the Expansion Space, the First Preferential
               Space, and the Second Preferential Space, as the case may be,
               relative to the forty-two (42) month minimum term provided
               herein.  If Tenant exercises its First Cancellation Option with
               respect to any portion of the Leased Premise, Tenant at its sole
               cost and expense, shall be responsible for the installation of a
               demising partition separating that portion of the Leased Premises
               being canceled from any remaining portion of the Leased Premises
               not so canceled.  Moreover, at all times following the giving of
               such notice and prior to the effective date of cancellation of
               this Lease with respect to the applicable portion(s) of the
               Leased Premises, Tenant shall be bound by and obligated to comply
               with the covenants, duties and obligations of Tenant under this

          (4)  If Tenant exercises its First Cancellation Option with respect to
               any portion of the Leased Premises, any option(s) for additional
               space outstanding at the time of said cancellation shall become
               null and void.

     B.   Second Cancellation Option

               this Lease with respect to the entirety of the Leased Premises
               located on the sixth

               Stipulated Damages calculated pursuant to Subparagraph 28.B(2)
               below. Tenant must give Landlord written notice of its intent to
               exercise this option and on or before July 31, 1999.

          (2)  Stipulated Damages shall be due and payable simultaneous with
               Tenant's written notice of intent to cancel under the provisions
               of this Paragraph 28.B or Tenant's cancellation rights shall be
               null and void.  If Tenant exercises its Second Cancellation
               Option pursuant to this Paragraph 28.B, Tenant shall pay
               Landlord, as "Stipulated Damages", the sum of the following:

               (a)  The unamortized portion of Landlord's contributions, rental
                    abatement, moving allowance, and any other reimbursement
                    (collectively "Contributions") applicable to the Leased
                    Premises.  The costs of any asbestos abatement shall be
                    excluded from the calculation of the Contributions.  For
                    purposes of calculating Stipulated Damages, Contributions
                    shall be treated as if such were a loan, fully amortized
                    over the original term of the Lease at twelve percent (12%)
                    annual interest, compounded monthly.  Stipulated Damages as
                    outlined herein are subject to adjustment for any Expansion
                    Space and/or Preferential Right Space leased by Tenant
                    pursuant to Paragraph 25 and Paragraph 26.  Amortization of
                    Contributions attributable to the Expansion Space, the First

                    begin upon the commencement of the respective additional
                    space leased; plus

               (b)  An amount equal to one (1) month's Base Rental based on the
                    Base Rental being paid by Tenant at the time of said
                    cancellation.

          (3)  Tenant's Second Cancellation Option under this Paragraph 28.B
               shall be subject to the condition that (i) an Event of Default
               shall not have occurred at the time of exercise and is
               continuing, (ii) Tenant relocates its corporate offices outside

               Space, the Second Preferential Space, or any expansion thereof
               each for a minimum of forty-two (42) months.  Therefore, the
               Lease and/or any amendment(s) thereto may be terminated
               separately depending on the commencement date of the original
               Leased Premises, the Expansion Space, the First Preferential
               Space, or the Second Preferential Space, as the case may be,
               relative to the forty-two (42) month minimum term provided
               herein.  If Tenant exercises its Second Cancellation Option with

                                      -29-
<PAGE>

               respect to any portion of the Leased Premises, Tenant, at its
               sole cost and expense, shall be responsible for the installation
               of a demising partition separating that portion of the Leased
               Premises being canceled from any remaining portion of the Leased
               Premises not so canceled.  Moreover, at all times following the
               giving f such notice and prior to the effective date of
               cancellation of this Lease with respect to the applicable
               portion(s) of the Leased Premises, Tenant shall be bound by and
               obligated to comply with the covenants, duties and obligations of
               Tenant under this Lease, including without limitation the payment
               of Base Rental and all other sums due and payable by Tenant
               hereunder.

          (4)  If Tenant exercises its Second Cancellation Option with respect
               to any portion of the Leased Premises, any option(s) for
               additional space outstanding at the time of said cancellation
               shall become null and void.

     Provided that Tenant (i) shall not at such time be in default of any of the
terms or provisions of the Lease; (ii) shall be in occupancy of the entire
Leased Premises; and (iii) subject to any existing preferential rights to lease,

Option") to renew the Lease for one (1) additional five (5) year period (the
"Renewal Period"), commencing on the first day following expiration of the
initial term of the Lease, except that the rental rate shall be at the Fair

information from Landlord, Tenant shall give Landlord written notice of the
exercise of its Renewal Option.  Failure of Tenant to give such notice within
such thirty (30) days period shall cause such Renewal Option to be void and of
no further force and effect.  If Tenant exercises this Renewal Option, the First
Cancellation Option provided in Paragraph 28.A above shall be null and void.

30.  HOUSTON CITY CLUB

     Landlord agrees to pay, out of the Base Rent payable for the first (1st)
month of the term of this Lease for which Base Rent is due, on behalf of Tenant,

31.  HAZARDOUS MATERIAL; INDEMNITY

                                      -30-
<PAGE>

     A.   Tenant shall not cause or permit any Hazardous Material (as
          hereinafter defined) to be brought upon, kept or used in or about the
          Leased Premises or the Project by Tenant or its agents, employees,
          contractors or invitees without the prior written consent of Landlord
          (which Landlord shall not unreasonably withhold as long as Tenant
          demonstrates to Landlord's reasonable satisfaction that such Hazardous
          Material is necessary or useful to Tenant's business and will be used,
          kept and stored in a manner that complies with all laws regulating any
          such Hazardous Material so brought upon or used or kept in or about
          the Leased Premises or the Project).  If Tenant breaches the
          obligations stated in the preceding sentence, or if the presence of
          Hazardous Material on the Leased Premises or the Project caused or
          permitted by Tenant results in contamination of the Leased Premises or
          the Project, or if contamination of the Leased Premises or the Project
          by Hazardous Material otherwise occurs for which Tenant is legally
          liable to Landlord for damage resulting therefrom, then Tenant shall
          indemnify, defend and hold Landlord harmless from any and all claims,
          judgments, damages, penalties, fines, costs, liabilities or losses,
          including, without limitation, diminution in value of the Leased
          Premises, damages, penalties, fines, costs, liabilities or losses
          (including, without limitation, restriction on use of rentable or
          usable space or of any amenity of the Leased Premises or the Project
          [line missing] damages arising from any adverse impact on marketing of
          space, and sums paid in settlement of claims, attorney's fees and
          expert fees) which arise during or after the term of the Lease as a
          result of such contamination.  This indemnification of Landlord by
          Tenant includes, without limitation, costs incurred in connection with
          any investigation of site conditions or any clean up, remedial,
          removal or restoration work required by any federal, state or local
          governmental agency or political subdivision because of Hazardous
          Material present in the soil or ground water on or under the Leased
          Premises or the Project.  Without limiting the foregoing, if the
          presence of any Hazardous Material on the Premises or the Project
          caused or permitted by Tenant results in any contamination of the
          Leased Premises or the Project, Tenant shall promptly take all actions
          at its sole expense as are necessary to return the Leased Premises and
          the Project to the condition existing prior to the introduction of any
          such Hazardous Material to the Leased Premises or the Project;
          provided that Landlord's approval of such actions shall first be
          obtained, which approval shall not be unreasonably withheld so long as
          such actions would not potentially have any material adverse long-term
          or short-term effect on the Leased Premises or the Project.  The
          indemnification of Landlord by Tenant contained in this Paragraph 30
          shall survive the expiration or earlier termination of this Lease.

     B.   As used herein, the term "Hazardous Material" means any hazardous or
          toxic substance, material or waste which is or becomes regulated by
          any local governmental authority, the State of Texas or the United
          States Government, including, but not limited to, any material or
          substance that is (i) petroleum, (ii) asbestos, (iii) designated as a
          "hazardous substance" pursuant to Section 311

                                      -31-
<PAGE>

          of the Water Pollution Control Act (33 U.S.C. Section 1321), (iv)
          designated as a "hazardous waste" pursuant to Section 1004 of the
          Resource Conversation and Recovery Act, 42 U.S.C. Section 6901, (v)
          defined as a "Hazardous substance" pursuant to Section 101 of the
          Comprehensive Environmental Response, Compensation and Liability Act,
          42 U.S.C. Section 9601, or (vi) defined as a "regulated substance"
          pursuant to Subchapter IX, Solid Waste Disposal Act, 42 U.S.C. Section
          6991.

     C.   Landlord advises Tenant that, per the building inspection performed by
          Law Engineers in 1985 and McClelland Management Services in 1990, the
          following materials in Two Greenway Plaza were found to contain
          asbestos in amounts greater than one percent (1%): (i) sprayed-on
          fireproofing applied to the concrete structure throughout most of the
          Building; (ii) cementitious white mud insulation on the heat exchanger
          tanks in the basement mechanical room; (iii) pipe fitting and pipe run
          insulation (thin white mud-mastic type) on hot and chilled water lines
          throughout the Building mechanical rooms; (iv) tar coated pipe fitting
          insulation and pipe run insulation (black tar) on the chilled and hot
          water lines through the Building mechanical rooms; (v) cementitious
          white mud insulation on the condensate drain line in the Building
          mechanical rooms; and (vi) tar coating n duct insulation in the
          basement mechanical room.  The materials noted in (i) through (vi)
          above have been removed from floors one through five, seven through
          eleven and a portion of six of the Building.  If Tenant leases
          additional space pursuant to any option or preferential right
          contained in this Lease and said additional space contains asbestos,
          Landlord, at its sole cost and expense, will cause to have said
          asbestos removed.

32.  MISCELLANEOUS

     A.   Provided Tenant complies with its covenants, duties and obligations
          hereunder, Tenant shall quietly have, hold and enjoy the Leased
          Premises subject to the terms and provisions of this Lease.

     B.   In any circumstance where Landlord or Landlord's Mortgagee (or their
          agents or employees) are permitted to enter the Leased Premises, no
          such entry shall constitute an eviction or disturbance of Tenant's use
          and possession of the Leased Premises; be a breach by Landlord of any
          of its obligations; render Landlord liable for damages; entitle Tenant
          to be relieved from any of its obligations; nor grant Tenant any right
          of setoff, recoupment or other remedy.  In connection with any such
          entry incident to performance of repairs, replacement, maintenance or
          construction, all of the aforesaid provisions shall be applicable
          notwithstanding that Landlord may elect to take building materials in,
          to or upon the Leased Premises.

                                      -32-

     C.   Tenant will not assert any claim or counterclaim against Landlord of
          whatever nature or description in any legal proceeding unless during
          the pendency of the proceeding Tenant pays to Landlord or into the
          registry of the court all rent as it becomes due under this Lease.

     D.   The remedies of Landlord shall be cumulative; whether exercised by
          Landlord or not shall be deemed to be in [line illegible] otherwise
          provided in this Lease, granting of consent is within the sole
          discretion of the party whose consent is required and withholding of
          such consent need not be reasonable or based on good cause.

     E.   Where Tenant is required to pay any sum or do any act at a particular
          time or within an indicated period, it is understood that time is of
          the essence.

     F.   The obligation of Tenants to pay all rent and other sums provided
          under this Lease to be paid by Tenant and the obligation of Tenant to
          perform Tenant's other covenants and duties under this Lease
          constitute independent, unconditional obligations to be performed at
          all times provided for under this Lease, save and except only when an
          abatement, reduction or offset right is expressly provided in this
          Lease, and not otherwise.  Tenant waives any right to assert, as
          either a claim or defense, that Landlord is obligated to perform or is
          liable for the nonperformance of any implied covenant or implied duty
          of Landlord not expressly set forth in this Lease.  Tenant waives any
          implied warranty by Landlord that the Leased Premises are suitable for
          their intended commercial purposes; provided that such waiver shall
          not relieve Landlord of its express obligations under this Lease,
          specifically including without limitation its obligations regarding
          construction and maintenance and repair of the Leased Premises.  Other
          than as expressly set forth in this Lease, Landlord makes no express
          warranty nor shall there be any implied warranty regarding the
          condition of the Leased Premises.  Tenant agrees to perform all of its
          obligations hereunder (including, without limitation, the obligation
          to pay rent), irrespective of any breach or alleged breach by Landlord
          of any such implied warranty; provided that Tenant shall have the
          right to bring an action for injunction or for damages caused by such
          breach.  Tenant agrees that Landlord shall incur no liability to
          Tenant by reason of any defect in the Leased Premises, whether
          apparent or latent.  Tenant waives and relinquishes all rights which
          Tenant might have to claim any nature of lien against any rent or
          other sums payable by Tenant under this Lease.  Notwithstanding the
          foregoing, Landlord's contractor will warrant the workmanship of the
          construction performed within the Leased Premises for a one (1) year
          period from Substantial Completion ("Contractor Warranty").  Landlord
          will use good faith efforts to enforce said Contractor Warranty.

                                      -33-
<PAGE>

     G.   Under no circumstances whatsoever shall Landlord or Tenant ever be
          liable for consequential damages or special damages.  Tenant waives
          and relinquishes all rights which Tenant may have to claim any kind of
          prejudgment lien against rent owed Landlord or against Landlord's
          property.

     H.   All monetary obligations of Landlord and Tenant (including, without
          limitation, any monetary obligation of Landlord or Tenant for damages
          for any breach of their respective covenants, duties or obligations)
          are performable exclusively in Houston, Harris County, Texas.

     I.   If any provision of this Lease shall ever be held to be invalid or
          unenforceable, such invalidity or unenforceability shall not affect
          any other provision of the Lease, but such other provisions shall
          continue in full force and effect.

     J.   The term "Landlord" shall mean only the owner, for the time being, of
          the Building.  Landlord reserves the right to transfer, assign or
          convey, in whole or in part, the building, the Land, the Project, any
          interest in any of the foregoing and its interest in this Lease.  In
          the event of the transfer by such owner of its interest in the
          Project, Building or this Lease, such owner shall thereupon be
          released and discharged from all covenants and obligations of the
          Landlord thereafter accruing; but such covenants and obligations shall
          be binding during the Lease term upon each new owner of the Project or
          Building (or assignee of the Landlord's interest under this Lease) for
          the duration of such owner's ownership.  All liability of Landlord for
          damages for breach of any covenant, duty or obligation of Landlord
          hereunder shall be satisfied only out of the interest of Landlord in
          the Building existing at the time any such liability is adjudicated in
          a proceeding as to which the judgment adjudicating such liability is
          nonappealable and not subject to further review.

     K.   Tenant represents and warrants that it has not been represented by any
          broker or agent in connection with the negotiation or execution of
          this Lease, except for Lewis Partners, Inc.  Tenant shall indemnify
          and hold harmless Landlord and Landlord's designated property
          management firm from and against all claims (including costs of
          defending against and investigating such claims) of any broker or
          agent or similar party claiming by, through or under Tenant in
          connection with this Lease.

     L.   Whenever either party is required to pay for attorneys' fees,
          realtors' commissions or other professional fees and expenses on
          behalf of the other party, such fees and commissions shall be
          commercially reasonable.

                                                                   Exhibit 10.10

     THIS FIRST AMENDMENT OF LEASE CONTRACT (the "First Amendment") is entered
into between CRESCENT REAL ESTATE FUNDING III, L.P., a Delaware limited
partnership ("Landlord"), and PHYSIX, INC., a Texas corporation ("Tenant"), with
reference to the following:

     A.   Greenway Plaza, Ltd. (predecessor-in-interest to Landlord) and Tenant
entered into a Lease Contract dated October 2, 1996 covering approximately 7,433
square feet of Rentable Area (the "Original Leased Premises") on the sixth (6th)
floor of Two Greenway Plaza, Houston, Texas (the "Building").

     B.   Landlord and Tenant now wish to amend the Commencement and Expiration
Dates set forth in Paragraph 2 of the Lease; further expand the Leased Premises
pursuant to Tenant's exercise of its First Preferential Right; and otherwise
amend the Lease as set forth more fully below.  Unless otherwise expressly
provided herein, capitalized terms used herein shall have the same meanings as
in the Lease.

     FOR GOOD AND VALUABLE CONSIDERATION, the receipt and sufficiency of which
are acknowledged, the parties agree as follows:

1.   First Preferential Space.

     (a)  Pursuant to Paragraph 26.A. of the Lease, Landlord leases to Tenant
and Tenant leases from Landlord approximately 3,144 square feet of additional
Rentable Area located on the sixth (6th) floor of the Building shown outlined
and hatched on Exhibit "B" attached hereto and made a part hereof (the "First
Preferential Space"). The term of the Lease with respect to the First
Preferential Space shall commence upon Substantial Completion (as defined in
Paragraph 5(c) of the Construction Agreement attached hereto as Exhibit "D') of
leasehold improvements therein and shall expire upon the expiration of the
initial term of the Lease.

     (b)  Landlord shall, at its expense, use reasonable good faith efforts to
achieve Substantial Completion in the First Preferential Space on or before July
1, 1997.  If Substantial Completion has not been achieved by such date for any
reason, Landlord shall not be liable to Tenant for any claims, damages, costs or
liabilities arising by reason of such delay.  However, in such event, Landlord
and Tenant shall, promptly upon request, execute an agreement specifying the
date of Substantial Completion in the First Preferential Space, with a
corresponding adjustment to the schedule of Base Rental set forth below.

     (c)  Upon Substantial Completion of the First Preferential Space, the term
"Leased Premises" as used in the Lease shall mean and include approximately
10,577 square feet of Rentable Area, being the sum of the Original Leased
Premises and the First Preferential Space.

2.   Commencement Date.  In Paragraph 2 of the Lease, the Commencement Date
shall be changed to "November 15, 1996" and the Expiration Date shall be changed
to "March 31, 2004."

3.   Base Rental.

     (a)  Tenant shall pay Landlord Base Rent for the First Preferential Space
in accordance with the following schedule:


          FROM                  TO                      MONTHLY BASE RENTAL

          July 1, 1997          September 14, 2000            $3,144.00
          September 15, 2000    March 31, 2004                $3,406.00

5.   Construction.

     (a)  The Work.  Subject to the terms of this Construction Agreement,
Landlord agrees to construct leasehold improvements (the "Work") in a good and
workmanlike manner in and upon the First Preferential Space in accordance with
the Approved Construction Documents.
<PAGE>

     (b)  General Construction Terms.  Landlord will employ an experienced,
licensed contractor to construct the Work and will require in the construction
contract that such contractor construct the Work in a good and workmanlike
manner and in compliance with all Applicable Laws, except as otherwise provided
herein or in the Lease.  The parties acknowledge that Landlord is not an
architect or engineer, and that the Work will be designed and performed by
independent architects, engineers and contractors.  Accordingly, Landlord does
not guarantee or warrant that the Approved Construction Documents will be free
from errors or omissions, nor that the Work will be free from defects, and
Landlord will have no liability therefor. In the event of such errors,
omissions, or defects, Landlord will use reasonable efforts to cooperate in any
action Tenant desires to bring against such parties.

     (c)  Substantial Completion.  All work shall be deemed "Substantially
Completed" when completed in accordance with this Exhibit and the Approved
Construction Documents, to the extent that Tenant would have access to the First
Preferential Space and be able to conduct its business in a reasonable manner
and Landlord has obtained final inspection approval from the City of Houston,
even though adjustments or corrections may be necessary and minor "punch-list"
items remain to be completed.

     (d)  ADA Compliance.  Landlord shall be responsible for costs and
implementation associated with compliance with the Americans with Disabilities
Act, including any state or local laws relating thereto ("ADA") for the Project
and all points of access into the Project ("the Landlord's ADA Work").  Tenant
shall be responsible for all costs and implementation associated with ADA
compliance within the First Preferential Space (including restrooms). Landlord
shall not be responsible for determining whether Tenant is a public
accommodation under ADA or whether the Approved Construction Documents comply
with such laws and the regulations thereunder.  Such determinations, if desired
by Tenant, shall be the sole responsibility of Tenant.

6.   Costs.

     (a)  Overruns.  Costs incurred by Landlord in excess of the Construction
Allowance shall be paid by Tenant to Landlord promptly within ten (10) calendar
days following delivery of Landlord's invoice. Change orders requested by Tenant
and approved by Landlord which increase the cost of construction shall be paid
by Tenant to Landlord promptly upon demand.

     (b)  Construction Management Fee.  Within ten (10) calendar days following
the date of invoice, Tenant shall pay Landlord a "Construction Management Fee"
equal to ten percent (10%) of the contract price for the Work in excess of the
Design and Construction Allowance for supervision and administration of the
construction and installation of the Work. Tenant agrees that in the event of
default of payment thereof, Landlord (in addition to all other remedies) shall
have the same rights as in the event of default of payment of rent under the
Lease.

7.   Delays. If Landlord is delayed in completing construction of the Work for
any reason other than Tenant Delays, the delay in commencement of Tenant's
obligation to pay rent under the Lease shall constitute full settlement of all
claims that Tenant may have against Landlord based on the delay. If Landlord is
delayed in completing the Work due to a delay caused by Tenant or for any other
cause related to Tenant's acts or omissions, Tenant's rental obligations under
the Lease shall begin on the date on which Landlord would have delivered
possession of the First Preferential Space to Tenant absent such delay, and such
date shall be the Commencement Date.

     C.   Amendment to Annex A to the Agreement.  Annex A to the Agreement is
          hereby deleted in its entirety and replaced by Annex A attached hereto
          and incorporated by reference herein.

     Section 2.  Additional Marquette Obligations -- Installed Base List.

     A.   Delivery.  Within 30 days of the execution of this Agreement,
          Marquette shall deliver to DCC a list of its customers located in the
          U.S. and Canada to whom it has sold any telemetry products or
          equipment manufactured by it that are compatible with the Products, as
          determined by Marquette (the "Installed Base List").

     B.   Limited Use and Confidentiality.  DCC acknowledges and agrees that the
          Installed Base List shall be considered Confidential Information of
          Marquette pursuant to the Agreement.  Notwithstanding anything to the
          contrary, the Installed Base List shall be used by DCC for the sole
          purpose of selling or leasing the Products to end users, and shall not
          be used for any other purpose without the prior written consent of
          Marquette.  The Installed Base List shall be disclosed only to those
          employees of DCC with a need to know, provided that any such persons
          are informed of and agree to abide by the confidentiality provisions
          of the Agreement and this Section 2.

     C.   No Warranty.  Marquette make no warranties under this Agreement with
          respect to the Installed Base List. The Installed Base List and all
          information contained therein are provided AS IS. NO WARRANTIES,
          INCLUDING BUT NOT LIMITED TO IMPLIED OR EXPRESS WARRANTIES OF
          MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, SHALL APPLY TO
          THE INSTALLED BASE LIST.

     D.   Equitable Relief.  DCC acknowledges and agrees that its failure to
          comply with the provisions of this Section 2 will cause irreparable
          harm to Marquette, the dollar amount of which will be difficult to
          determine.  Therefore, DCC agrees that Marquette may seek and obtain
          equitable relief, including without limitation any


                                      -2-

          temporary or permanent injunction, with respect to any breach of this
          Section 2 by DCC.

Section 3.  Additional DCC Obligations

          calendar quarter, beginning on the calendar quarter ending March 31,

          to Marquette, in form agreeable to Marquette, setting forth the
          following information:

          (i)   all Products installed by DCC or its affiliates in the

          (iv)  the total Net Revenue (as defined below) to DCC from the

                Section 3.B hereof;

          (vi)  a detailed review of Product performance and customer
                satisfaction for such quarter; and

          (vii) additional sales opportunities with respect to sales of Products
                by Marquette.

     B.   Royalty.

                any Person other than Marquette.

          (ii)  Payment of Royalties. Each Quarterly Report shall be accompanied
                by payment of the royalty amounts (the "Royalty Payment") due
                Marquette as calculated in the Quarterly Report. Payments due to
                Marquette hereunder shall be paid in U.S. Dollars by corporate

                account designated by Marquette or in such other reasonable form
                and at such other reasonable place as Marquette may hereafter
                designate by notice

          (iii) Net Revenue. As used herein, the term "Net Revenue" means the
                "Gross Revenue" received by DCC but excluding, if separately
                stated, sales taxes,

                warranty charges, freight, shipping insurance and shipping
                costs. "Gross Revenue" shall mean consideration of all types
                received by DCC from sales or leases of Products to any Person
                (other than Marquette) including, but not limited to, money,
                securities and in-kind contributions to research efforts, with
                any consideration other than money being valued at its fair
                market value on the date received by DCC.

     C.   Exclusivity.

          (i)   DCC covenants and agrees that it will not license or otherwise
                make commercially available the View on Demand Feature (as
                defined below) to or assist any other Person to develop a
                product competitive with the View on Demand Feature. The
                foregoing exclusivity shall expire as of any calendar quarter
                for which the Net Revenues derived from the sum of (1) each
                Product installed by DCC and (2) the value of all Products for
                new installations shipped by DCC to Marquette and their
                affiliates and agents, fall below the Targets set forth below or
                any Subsequent Targets (as defined herein) for the relevant
                period:

<TABLE>
<CAPTION>
     Period                                     Target
     ------                                     ------

     Second Quarter 2000                         $[*]
     Third Quarter 2000                          $[*]
     Fourth Quarter 2000                         $[*]
</TABLE>

                Solely for purposes of calculating the Net Revenue derived from
                each Product installed by DCC pursuant to clause (1) of this
                Section 3.C(i), the Net Revenue derived from each such Product
                shall be deemed to be $[*].

          (ii)  If the exclusivity granted hereunder has expired, the OEM Prices
                set forth in Annex A to the Agreement, as amended hereby, may be
                increased by no more than [*]% upon such expiration and annually
                thereafter on each anniversary of the expiration of the
                exclusivity.

          (iii) Solely for purposes of this Section 3.C, Net Revenue shall not
                include any Royalty Payments paid by DCC to Marquette hereunder.
                In addition, to the extent that Net Revenues for any calendar
                quarter exceed the applicable Target for such quarter, such
                excess Net Revenue shall carry over into the next calendar
                quarter and shall be added to the Net Revenue

                for such quarter solely for the purposes of calculating the
                Target for such quarter in accordance with this Section 3.C.

          (iv)  So long as the exclusivity granted hereunder remains applicable,
                the parties hereto agree to negotiate in good faith and come to
                mutual written agreement no later than December 1 of each year,
                with respect to revised quarterly Targets applicable to each
                calendar year during the Term of the Agreement (the "Subsequent
                Targets"); provided, however, that upon the failure of the
                parties to agree to such Subsequent Targets as of such December
                1, the parties shall submit their dispute to the arbitration
                provisions set forth in Section 20 of the Agreement, with any
                such arbitration occurring in Chicago, Illinois.

          (v)   So long as the exclusivity granted hereunder remains applicable,
                at least 25 days prior to (but no more than 30 days prior to)
                the end of each calendar quarter, DCC shall deliver to Marquette
                a written report (the "Exclusivity Report") setting forth (i)
                the total number of Products installed by it to Persons (other
                than Marquette) for the then current fiscal quarter as of the
                date of the Exclusivity Report; (ii) the Net Revenue derived
                from the Products so installed; (iii) DCC' s best estimate of
                the Net Revenue to be derived from the Products so installed for
                the remainder of the then current fiscal quarter.

          (vi)  DCC agrees to keep accurate and correct books and records
                appropriate to determine the amount of royalties due Marquette
                hereunder. Records with respect to each installation of Products
                shall be retained for a period of three (3) years. During the
                term of the Agreement, and for an additional period of three (3)
                years thereafter, DCC agrees that its books, records and other
                documents shall be available during normal business hours for
                inspection by an independent certified public accountant
                selected by Marquette and reasonably acceptable to DCC for the
                sole purpose of verifying reports and payments due hereunder and
                otherwise confirming DCC's performance of its obligations
                hereunder; provided that such accountant shall first agree in
                writing to maintain all information learned in such inspection
                in strict confidence except as reasonably necessary to explain
                to Marquette any breach by DCC hereunder. No such inspection
                shall unreasonably interfere with normal business activities
                conducted by DCC. If such review reveals an underpayment of
                royalties due hereunder of more than five percent (5%), DCC
                shall pay all of Marquette's costs associated with such review.

          (vii) For purposes of this Agreement, the "View on Demand Feature"
                shall mean the ability to use a button built into the patient's
                telemetry pack to cause a current sample ECG waveform page to be
                transmitted to the Product's assigned receiver(s).

     D.   Infringement.  DCC shall not use or incorporate into the Products or
          other technology or items furnished hereunder any copyrighted,
          patented or proprietary materials of any other Person without the
          written authorization of such Person. DCC shall defend, indemnify and
          hold Marquette, its affiliates or their customers harmless from any
          and all claims, suit, or other proceeding ("Claims") brought against
          Marquette, its affiliates or their customers that any Product or
          process resulting from its use infringes or misappropriates any
          patent, copyright or trade secret of any other Person. Marquette shall
          notify DCC promptly in writing of any such Claim and shall grant to
          DCC such authority, information and assistance at DCC's expense as may
          be reasonably necessary for DCC to defend any such Claim; provided,
          however, that any failure by Marquette to so promptly notify or
          provide such authority, information, or assistance shall reduce the
          indemnity hereunder solely to the extent that DCC is actually
          prejudiced by such failure. DCC shall pay all damages and costs
          awarded against Marquette, its affiliates or their customers with
          respect to any such Claim, including reasonable attorneys fees. If use
          of any Product or other item is enjoined, DCC shall, at its sole
          expense, procure the right to continue using the Product or item,
          replace the Product or item with a non-infringing equivalent, or with,
          Marquette's written approval, remove the Product or item and refund
          the purchase price and any transportation and installation cost.
