ITEM 1.  BUSINESS
 
GENERAL
 
     Cardiometrics, Inc. ("Cardiometrics" or the "Company") develops,
manufactures and markets intravascular medical devices to measure blood flow
impairment caused by coronary artery disease. Cardiometrics' principal products,
the FloWire(R) Doppler guide wire and FloMap(R) ultrasound instrument, represent
an advance in functional testing of blood flow impairment, enabling
cardiologists to evaluate the appropriateness of angioplasty interventions and
assess post-procedural results directly in the cardiac catheterization
laboratory ("cath lab"). Clinical experience demonstrates that the measurement
of blood flow impairment downstream from (distal to) an obstruction, which
Cardiometrics calls functional angiometry, provides information to improve the
quality of patient care and procedure outcomes in the diagnosis and treatment of
cardiovascular disease. The FloWire/FloMap system has received clearance from
the U.S. Food and Drug Administration ("FDA") and many corresponding European
and Pacific Rim regulatory agencies. As of December 1996, more than 65,000
FloWire guide wires have been sold and cumulative FloMap shipments were
approximately 490.
 
     Cardiometrics has also developed the WaveWire(TM)/WaveMap(TM) intracoronary
blood pressure measurement system, which was first used in a clinical case in
Europe in December 1996. Cardiometrics submitted a 510(k) application for the
WaveWire/WaveMap system in December 1996 and expects the product will be
available for sale in international markets as early as the second half of 1997.
 
     Cardiometrics' goal is to improve the quality of care and patient outcomes
by enhancing cost-effective diagnostic and interventional decision making for
patients with intravascular diseases. Key elements of Cardiometrics' business
strategy are to: (i) establish functional angiometry as a new "gold standard" in
the diagnosis of coronary artery disease to be used in conjunction with
angiography; (ii) establish functional angiometry as a primary tool for
assessing the results of interventions and the need for stent placement; (iii)
increase the reimbursement of functional angiometry; (iv) increase the rate of
FloWire usage with the installed base of FloMap instruments; and (v) utilize
Cardiometrics' core technologies to develop devices for other markets and
applications.
 
POTENTIAL MERGER
 
     On January 26, 1997, Cardiometrics, EndoSonics Corporation, a Delaware
Corporation ("EndoSonics"), and River Acquisition Corporation, a Delaware
Corporation and a wholly owned subsidiary of Endosonics ("Merger Sub"), entered
into an Agreement and Plan of Reorganization (the "Reorganization Agreement"),
pursuant to which Merger Sub will be merged with and into Cardiometrics (the
"Merger"), with Cardiometrics surviving the Merger and becoming a wholly owned
subsidiary of EndoSonics. The consummation of the Merger is subject, among other
things, to the approval of the Merger by the stockholders of Cardiometrics, at a
stockholders meeting currently expected to be held in May 1997, and the
satisfaction of certain other closing conditions.
 
     Pursuant to the Merger, each outstanding share of Common Stock of
Cardiometrics ("Cardiometrics Common Stock") will be converted, without any
action on the part of the holder thereof, into the right to receive 0.35
newly-issued shares of EndoSonics Common Stock, 0.20 shares of CardioVascular
Dynamics, Inc. ("CVD") Common Stock held by Endosonics (subject to adjustment as
described below, the "CVD Exchange Ratio"), and $2.00 in cash (subject to
adjustment as described below, the "Cash Consideration," and together with such
shares of EndoSonics Common Stock and CVD Common Stock, the "Merger
Consideration"); with the CVD Exchange Ratio subject to increase, such that
based on the average of the closing prices of EndoSonics Common Stock and CVD
Common Stock to the ten trading days immediately preceding (and including) the
third trading day prior to the Cardiometrics Meeting, the Merger Consideration
shall equal $9.00; provided that, if the CVD Exchange Ratio obtained thereby
would exceed 0.2636, the CVD Exchange Ratio shall be 0.2636; provided further,
that EndoSonics has the right to substitute additional cash instead of
increasing the
 
                                        2
<PAGE>   3
 
CVD Exchange Ratio; and provided further, that the CVD Exchange Ratio shall not
be less than 0.20 and the Cash Consideration shall not be less than $2.00. If,
after such increase of the CVD Exchange Ratio or Cash Consideration, the Merger
Consideration is valued (based on the ten day averages described above) at less
than $8.00, then Cardiometrics may terminate the Reorganization Agreement. Each
outstanding option to purchase shares of Cardiometrics Common Stock (a
"Cardiometrics Option") will, pursuant to its terms, accelerate immediately
prior to the consummation of the Merger and become fully exercisable for all the
shares of Cardiometrics Common Stock at the time subject to that option. Upon
the consummation of the Merger, each Cardiometrics Option will be assumed in
part by EndoSonics and converted into an option to purchase 0.35 shares of
EndoSonics Common Stock for each share of Cardiometrics Common Stock subject to
that option immediately prior to the Merger, and the exercise price per share
payable under the assumed option will be appropriately adjusted to reflect such
conversion ratio. The balance of each Cardiometrics Option will be converted
into the right to receive a payment from EndoSonics, to be made in cash and
shares of CVD Common Stock, equal in value to (i) the portion of the Merger
Consideration paid in cash and shares of CVD Common Stock per outstanding share
of Cardiometrics Common Stock multiplied by the number of shares of
Cardiometrics Common Stock subject to the option immediately prior to the
Merger, less (ii) the difference between the aggregate option exercise price in
effect for that option immediately prior to the Merger and the aggregate
exercise price in effect for that option immediately after the partial
assumption by EndoSonics. Cardiometrics stockholders will receive cash in lieu
of fractional shares of EndoSonics Common Stock and CVD Common Stock. See the
Company's Current Report on Form 8-K filed with the Securities and Exchange
Commission on February 10, 1997 for further information regarding the Merger.
 
BACKGROUND
 
     Heart disease is the leading cause of death and disability in the United
States. Atherosclerosis, a principal form of heart disease, is a progressive and
degenerative process in which cholesterol and other fatty materials are
deposited on the walls of arteries, forming a build-up of plaque known as a
lesion. The accumulation of plaque, in turn, narrows the interior passage, or
lumen, of the blood vessels and in many cases impairs blood flow beyond the
blockage. Atherosclerosis in the coronary arteries, which carry oxygenated blood
to the heart, results in chest pain, known as angina, and can ultimately lead to
heart attack and death. In peripheral arteries atherosclerosis can lead to
decreased mobility, chronic pain and amputation. In the cerebrovasculature
atherosclerosis can lead to stroke.
 
  Treatment
 
     The primary treatment options for atherosclerosis are drug therapy,
Coronary Artery Bypass Grafting ("CABG") and Percutaneous Transluminal Coronary
Angioplasty ("PTCA" or "balloon angioplasty"). In addition, a variety of new
catheter based treatments have been developed to augment or replace balloon
angioplasty, including atherectomy, laser angioplasty and, most predominantly,
stent placement. Some drug therapies act directly to reduce the accumulation of
plaque or prevent additional plaque from forming, while others merely relieve
angina without eradicating the plaque itself. CABG surgery redirects blood flow
around one to four arterial blockages. Conduit vessels taken from elsewhere in
the body are grafted to the blocked vessels so blood can bypass the occlusion.
PTCA is a procedure in which a balloon tipped catheter is guided to the lesion
and then inflated and deflated several times to compress the plaque against the
vessel wall. The blockage is reduced by rupturing the plaque and stretching it
against the vessel wall.
 
     Although angioplasty is generally successful in initially opening the
blockage, between 30% and 40% of angioplasty patients suffer a significant
renarrowing of the treated blood vessel within six months after the procedure, a
process known as restenosis. Coronary blockages can also be treated with
atherectomy, which uses a mechanical device at the tip of a catheter to cut or
grind away plaque, and laser angioplasty, which delivers laser energy to break
down or ablate plaque. These devices are also associated with a high rate of
restenosis. The most significant recent development in the treatment of
 
                                        3
<PAGE>   4
 
coronary artery disease is the placement of stents. Stents are small metal
frames delivered to the lesion using a catheter and a guide wire, deployed
(i.e., expanded) and permanently left in the artery as an implant to maintain
the open lumen and improve blood flow. Because stents have been shown to reduce
the rate of restenosis from approximately 30-40% down to 20% or less, they are
rapidly gaining acceptance among and are increasingly being used by
cardiologists. However, due to the high cost of stenting and the difficulty of
reopening an area of restenosis which has already been stented, Cardiometrics
believes a new practice pattern of provisional or conditional stenting is
developing. Provisional stenting is the technique of identifying only those
lesions in which stents would provide optimum results given the increased cost
and improved clinical outcomes, rather than a blanket strategy of stenting each
lesion. Under provisional or conditional stenting, if aggressive balloon
angioplasty does not achieve satisfactory results, then stenting is performed.
 
  Diagnosis
 
     Coronary angiography is considered the "gold standard" in the diagnosis of
coronary artery disease. Coronary angiography is performed in the cath lab to
evaluate the location, size and shape of atherosclerotic lesions by injecting a
radiopaque dye via a catheter into the coronary arteries so that the relative
degree of narrowing of the vessels causing obstruction of blood flow may be
observed on an x-ray monitor. Based on a visual observation of the distribution
of the dye throughout the arteries, the cardiologist locates the lesion and
estimates the extent to which the obstructed artery is narrowed. The number and
distribution of lesions and the degree of narrowing of the affected arteries are
used to determine the course of treatment.
 
     While angiography is a vital tool in the diagnosis of coronary artery
disease, it requires subjective analysis and provides only limited information
about the affected vessels. Angiography provides no objective functional
information about the actual extent to which a lesion, regardless of its size,
interrupts blood flow to the myocardium. It is the disruption of blood
flow -- not the lesion itself -- that causes angina, heart attacks and
potentially death. In patients with lesions in more than one vessel, angiography
may not indicate which lesion is causing the patient's symptoms (the "culprit"
lesion). While some patients with multi-vessel disease need all of their lesions
treated, others have only one or more culprit lesions in need of treatment.
 
     Intravascular ultrasound imaging ("IVUS") is designed to augment
angiography. IVUS uses high frequency ultrasound to determine the position,
distribution, amount and composition of cardiovascular lesions. IVUS provides a
highly detailed anatomical view of a lesion and assists interventional
cardiologists in selecting which treatment option has the greatest chance of
success, in positioning therapeutic devices, especially stents, and in assessing
post-procedural results. However, like angiography, IVUS is an anatomical tool
that does not directly measure a lesion's effect on blood flow.
 
     Recognizing the limitations of angiography and other anatomical testing
such as IVUS, a joint committee of the American College of Cardiology ("ACC")
and American Heart Association ("AHA") published guidelines in 1993 that call,
in nearly all cases, for objective evidence of ischemia, or blood flow
impairment, as a justification for angioplasty. In addition, Medicare, in its
Coverage Issues Manual, specifies that Medicare covers balloon angioplasty only
if objective evidence of myocardial ischemia has been demonstrated.
 
     The traditional forms of functional testing, stress electrocardiography
("stress ECG"), stress echocardiography and stress perfusion imaging are each
performed outside of the cath lab. Functional angiometry with the FloWire/FloMap
system, however, is performed in the cath lab and, unlike the more traditional
functional tests, is a vessel specific test and thus can accurately determine
which blocked vessel impairs blood flow to the heart. The most common functional
test is stress electrocardiography, in which the electrical impulses of the
heart are recorded, usually while the patient exercises on a stationary bike or
treadmill. The ECG directly identifies the location of any electrical
disturbances, which is indirect evidence of impairment of blood flow to the
myocardium. Stress ECGs are often unreliable, especially in patients with single
vessel disease, among whom a large percentage falsely test
 
                                        4
<PAGE>   5
 
negative. Additionally, stress ECG may not identify the culprit lesion in
patients with multi-vessel disease. Stress echocardiography uses ultrasound to
create a visual representation of the heart. Since muscle motion or
contractility are affected by insufficient blood flow, areas with poor motion or
contractility provide indirect evidence of blood flow impairment. While the
results are more reliable than with stress ECG, stress echocardiography results
may vary from one institution to another and are susceptible to false negatives.
In addition, stress echocardiography is not appropriate for certain individuals
due to their body size or fat content. Stress perfusion imaging is a functional
test that measures impairment of blood flow to the myocardium, also known as a
perfusion defect. A radioactive substance, usually radionuclide thallium, is
injected intravenously. The heart is then scanned radiographically to determine
which areas of the myocardium the radionuclide reaches. If a particular region
of the myocardium shows little or no uptake of the radionuclide, there is
probably a flow limiting lesion in the artery that supplies that region with
blood.
 
     In addition to their individual limitations, each of these three stress
tests share a common limitation in that they must be performed outside of the
cath lab, often by a physician other than the interventional cardiologist. The
ability to perform functional testing of blood flow impairment in the cath lab
is significant because it enables the cardiologist to perform the test during
angiography. The blockage (a "lesion") within a diseased vessel can then be
appropriately treated without delay based on the results of functional
angiometry.

  FloWire
 
     The FloWire Doppler guide wire functions as an angioplasty guide wire for
crossing lesions and does not add to the number of devices required for
interventional applications. Previously developed catheter-based systems were so
large that once the lesion was crossed, the device itself interfered with blood
flow. Although these catheter-based systems can measure blood flow velocity
proximal to a lesion, such measurements are inadequate because they are
typically affected by flow through other branches of the vessel upstream from
the blockage.
 
     The FloWire uses Doppler ultrasound to perform blood flow velocity
measurements within blood vessels. An ultrasonic Doppler transducer mounted at
the tip of the FloWire transmits a signal that is reflected back by the red
blood cells flowing past the FloWire. The change in frequency between the
transmitted and reflected signals, the Doppler shift, is directly proportional
to the velocity of the moving red blood cells. The accuracy of FloWire
measurements is enhanced by a patented miniaturized sensor designed to provide a
wide ultrasound beam, which allows for a large sample volume encompassing the
central axis of small or medium size arteries. In addition, the Doppler sample
volume is positioned to ensure that the measurement is not affected by the wake
from the blood flowing around the wire.
 
     Under normal circumstances, blood flow increases during exertion to meet
the increased myocardial oxygen demand and coronary flow reserve is high. In the
presence of a flow limiting lesion, however, blood flow cannot increase to meet
the increased oxygen demand and coronary flow reserve is low. Low coronary flow
reserve provides objective, quantitative evidence that a coronary artery lesion
impairs blood flow and thus requires intervention.
 
     The patented electrical connection on the FloWire is designed to allow
complete compatibility with other devices, such as balloon catheters. This
design helps make use of the FloWire in the cath lab quick, convenient and easy
to integrate with other therapeutic devices. Use of the FloWire typically adds
no more than 5-10 minutes to the procedure.
 
     The electrical interface between the FloWire and the instrumentation is
accomplished using the disposable rotary connector cable. In 1994, after
receiving 510(k) clearance, Cardiometrics released a new cable which makes it
easier to insert the FloWire or SmartWire into the electrical connection. It
also improves the electrical continuity of the interface during handling.
 
  FloMap
 
     The FloMap ultrasound instrument transmits pulsed ultrasound signals to the
transducer at the tip of the FloWire, receives the returning Doppler signals and
processes the information using Doppler electronics. The FloMap analyzes the
frequency spectrum of the signals and converts the information to a velocity
measurement expressed in centimeters per second. The information is delivered
both graphically and numerically and is easily understood by physicians and
other trained personnel. The key functional measures obtained are average peak
velocity, diastolic-to-systolic flow velocity ratio, Doppler blood flow velocity
trend monitoring and distal coronary flow reserve, which is the ratio of
myocardial blood flow upon exertion to that at rest, measured distal to coronary
artery blockages. The continuous graphic display using a scrolling spectral
display on the monitor screen provides more valuable information regarding
signal reliability and accuracy than a simple mean or peak velocity trace. The
display is especially beneficial during interventions so that blood flow trends
may be continuously monitored.
 
     The FloMap was originally developed as a freestanding, portable unit with
its own monitor. The newly developed FloMap II, a smaller unit about the size of
a video cassette recorder, is attached to existing cath lab equipment and
transmits the display information and video to the existing cath lab monitors.
Once installed, the FloMap II becomes an integral part of the cath lab with its
own printer for documentation.
 
                                        6
<PAGE>   7
 
     The FloMap and FloMap II can be and usually are operated via a hand held
remote control unit, called the FloMote(TM). Cardiometrics released in 1996 a
modified remote control in which the keys have been reconfigured for improved
ease of use. In particular, alphanumeric keys have been added for faster patient
data entry prior to a procedure. The new FloMote is also more ergonomic, with
the most important keys being larger and ideally placed for simple, one handed
operation.
 
  SmartWire
 
     The SmartWire uses the same ultrasound technology as the FloWire to assess
blood flow abnormalities in the cerebrovasculature. The physical design
characteristics of the SmartWire guide wire, such as the longer flexible distal
coil segment relative to the FloWire, make it suitable for use in the
cerebrovasculature.
 
  SmartMap
 
     The SmartMap ultrasound instrument is a portable, freestanding unit similar
to the FloMap ultrasound instrument with minor modifications for the
cerebrovascular application. The SmartMap software has been specifically
configured to include parameters of interest to the interventional
neuroradiologist during cerebrovascular diagnostic procedures and interventions.

MARKETS
 
     The worldwide market potential for the FloWire/FloMap system is estimated
to be approximately 1,200,000 procedures annually for diagnostic and
interventional applications (assuming the same FloWire guide wire would be used
in the estimated 30% of balloon angioplasty procedures which are performed in
connection with diagnostic angiography outside of the United States). The
WaveWire/WaveMap system, when commercially introduced, will address these same
markets.
 
  Diagnostic Applications in the U.S. Market
 
     There were approximately 1,560,000 coronary angiographies performed in the
U.S. in 1994 according to MDI. The results of a published study indicate that
approximately 53% of all angiography patients have intermediate lesions.
Accordingly, Cardiometrics estimates that in 1994 approximately 825,000
angiography patients in the U.S. had intermediate lesions. Cardiometrics further
estimates that approximately one-half, or 410,000, of the patients were not
functionally tested prior to a treatment decision. Many of these patients who
are not functionally tested either receive angioplasty without the justification
called for in published professional guidelines or do not receive angioplasty
even though a functional test might have demonstrated intervention was
clinically appropriate.
 
  Diagnostic Application in the International Market
 
     There were approximately 1,200,000 coronary angiographies performed outside
the U.S. in 1994 according to MDI. Of these angiographies, there were
approximately 435,000 multi-vessel disease patients with at least one
intermediate lesion based on Cardiometrics' analysis of published studies and
MDI market data. While these patients typically undergo stress ECG testing prior
to angiography, the FloWire/FloMap system enables the cardiologist to determine
in the cath lab the functional severity of each individual vessel involved to
identify the culprit lesion for intervention.
 
  Interventional Applications in the Worldwide Market
 
     There were approximately 947,000 percutaneous coronary interventions
worldwide in 1996, with 565,000 in the U.S. and an additional 382,000 such
procedures internationally according to Cowen & Company. The FloWire can be
integrated into angioplasty procedures by replacing the conventional
 
                                        7
<PAGE>   8
 
angioplasty guide wire. Since approximately 60% of percutaneous coronary
interventions involve balloon angioplasty, according to Cowen & Company, there
are an estimated 568,000 worldwide balloon angioplasty procedures. In these
procedures, FloWire measures of coronary flow reserve (CFR), combined with
angiography, can potentially be used to predict the recurrence of coronary
artery blockages, called restenosis, requiring a repeat angioplasty and may be
used to determine the need for further balloon angioplasty and stent placement
to optimize clinical outcomes.
 
  Applications for Patients with Normal Coronary Angiography
 
     A potential application of the FloWire is in diagnosing patients with
classic symptoms of angina, yet have no angiographic evidence of coronary artery
disease. Cardiometrics estimates that approximately 15%, or approximately
300,000 patients per year in the U.S., who undergo angiography fall into this
category. The symptoms in these patients are often caused by atherosclerosis of
the microvasculature or spasms of one or more coronary arteries, neither of
which can be detected with angiography. Either condition may be detected with
the FloWire. This diagnostic procedure has been adopted as a standardized
clinical protocol at the Mayo Clinic; however, Cardiometrics believes that
future publication of the Mayo Clinic's clinical outcomes and a simpler, faster
protocol will need to be developed prior to widespread adoption of the FloWire
for this application.
 
SALES AND MARKETING
 
     Cardiometrics directs its marketing efforts to interventional cardiologists
who diagnose and treat coronary artery disease. Cardiometrics also markets to
hospital and cath lab administrators in light of their expanding roles in
purchase decisions.
 
  Domestic Sales and Marketing
 
     A cumulative total of 139 FloMap instruments have been shipped within the
United States. Cardiometrics offers the option of providing the FloMap
instrument to institutions that agree to minimum FloWire purchase commitments at
non-discounted prices, thereby assuring consistent usage. The sales effort
focuses on routine clinical usage and the support of new clinical protocols
designed to expand markets and usage.
 
     Domestic sales are handled by a direct sales force headed by management
with extensive background and experience in the interventional cardiology
market. Cardiometrics currently has six regional field representatives who have
previous experience with interventional cardiology companies. The sales force
also includes one national training specialist dedicated to creating and
servicing educational sites. Cardiometrics is also exploring possible
distribution arrangements with major U.S. medical device companies.
 
     Cardiometrics has training centers at clinical sites with the most
experience with the FloWire/FloMap system. National training programs have been
held at Allegheny General Hospital and St. Louis University Hospital.
Experienced physicians often visit new installation sites to provide educational
support. Cardiometrics conducts training courses for cath lab personnel at its
home offices in California.
 
  International Sales and Marketing
 
     More than 300 FloMap instruments have been shipped to sites in more than 20
countries outside the U.S. International sales accounted for 75% of
Cardiometrics' 1996 revenues. Japan alone accounted for 41% of 1996 revenues.
Europe accounted for 29% and the rest of the world accounted for 5% of revenues
in 1996. Cardiometrics' success in Japan is due in part to the official
reimbursement status granted to the FloWire/FloMap system by the Ministry of
Health in 1992. The FloMap is installed in more than 100 cath labs in Japan.
 
                                        8

     Cardiometrics' international sales are managed by an international sales
and marketing group with extensive background and experience in the
interventional cardiology market. Cardiometrics also utilizes a network of 20
international distributors with experience in cardiology products, most of whom
represent other cardiology products. Cardiometrics' internal sales and marketing
staff manage these distributor relationships to coordinate overall sales efforts
and direct end user marketing. Cardiometrics also sponsors international
clinical studies and major European and Japanese symposiums to market its
products internationally. Three regional clinical managers, one in Paris, one in
Amsterdam and one in Seoul, train distributors and key customers overseas in the
clinical use of Cardiometrics' products.
 
     Cardiometrics typically enters into distribution agreements with its
international distributors, many of which are cancelable upon 90 days notice.
Most of Cardiometrics' international sales are made pursuant to individual
purchase orders placed by distributors.
 
     In Japan, Cardiometrics distributes its products through Goodman Co., Ltd.
("Goodman") and Kaneko Enterprises, Inc. ("Kaneko") pursuant to a distribution
agreement appointing Goodman and Kaneko as Cardiometrics' exclusive distributors
for its products in Japan through September 1999. In Germany, Cardiometrics
distributes FloWire devices and FloMap instruments through A.D. Krauth pursuant
to a distribution agreement which will expire at the end of 1997.
 
     In September 1995, Cardiometrics entered into an exclusive distribution
agreement with Cordis Europa, N.V., a subsidiary of Cordis, which was
subsequently acquired by Johnson & Johnson ("Cordis/Johnson & Johnson"), to
distribute the FloMap and SmartMap instruments and FloWire and SmartWire guide
wires in the United Kingdom, France, Spain, Scandinavia, South Africa and
certain Middle Eastern countries. Cordis/Johnson & Johnson is required to make
certain minimum purchases of these products during the term of the distribution
agreement in order to maintain its exclusive distribution rights. In 1996, the
Cordis/Johnson & Johnson agreement was extended through 1997 and Beneluex was
added to the Cordis/Johnson & Johnson's distribution territory. The distribution
agreement also provides that either party may immediately terminate the
agreement in the event that one of the parties is acquired by a third party.
Cardiometrics has entered into the Reorganization Agreement with EndoSonics and
upon the consummation of the Merger there can be no assurance that
Cardiometrics' distribution agreement with Cordis/Johnson & Johnson will not be
terminated. However, in light of EndoSonics' worldwide distribution
relationships with Johnson & Johnson, Cardiometrics believes the risk of
termination due to the Merger is very low. Also, Cordis/Johnson & Johnson is
Cardiometrics' exclusive distributor of the FloWire/FloMap system in Canada.
 
MANUFACTURING
 
     Cardiometrics purchases from outside vendors certain of the components
utilized in the manufacture of its products. These items are generally produced
to Cardiometrics' specifications and in many instances to Cardiometrics'
designs. Cardiometrics performs inspections and product tests at various steps
in its vendors' manufacturing process to ensure compliance with Cardiometrics'
specifications.
 
     Currently Cardiometrics produces transducer sensor fabrications and certain
mechanical parts in-house and maintains its in-house capability for all
fabrication and assembly processes. Many of the fabrication processes are
performed on specialized equipment which was designed and built specifically to
manufacture Cardiometrics' products. Guide wire assembly, testing, packaging and
final inspection occurs in a 2,300 square foot clean room. Packaged and
inspected guide wires are moved into a boxing area outside the clean room where
the product is boxed, labeled and prepared for shipment to Cardiometrics'
contract sterilizer. The product is ethylene oxide sterilized.
 
     Cardiometrics maintains rigorous quality control standards. All
manufacturing and testing is performed in accordance with FDA-issued Good
Manufacturing Practices ("GMP"), and Cardiometrics completed a successful GMP
inspection in January 1995. All materials are lot controlled and each FloWire
guide wire is serialized for full traceability. To date, Cardiometrics has not
needed to perform a voluntary or involuntary product recall. Cardiometrics has
made modifications to its
 
                                        9
<PAGE>   10
 
operations to comply with the ISO 9000 standards (European standards analogous
to GMP) and obtained the CE mark (European clearance analogous to FDA clearance)
under the European Medical Device Directive (93/42/EEC) and ISO 9000 standards
in January 1996.
 
     Most of the electrical assembly processes for the FloMap and SmartMap
instruments have been outsourced to allow Cardiometrics to focus on final
product assembly and testing. Cardiometrics configures instruments to the
customer's power and video requirements and functionally tests them at the
system level prior to shipment. The instruments are designed and manufactured to
meet or exceed required industry design and performance standards.
 
RESEARCH AND DEVELOPMENT
 
     Cardiometrics' research and development projects include enhancements to
existing products, the development of new products and clinical outcome studies
to support existing products, such as those discussed below.
 
  Product Enhancements and Development
 
     Cardiometrics has developed the WaveWire(TM)/WaveMap(TM) intracoronary
blood pressure measurement system to permit analysis of mean intracoronary
pressures as well as diastolic, systolic and other hemodynamic parameters. First
used in a clinical case in Europe in December 1996, the WaveWire is a 0.014 inch
clinical angioplasty guide wire with an electronic pressure sensor mounted 3
centimeters from the tip. The WaveMap is an instrument for processing and
displaying blood pressure information received from the WaveWire. Cardiometrics
submitted a 510(k) application for the WaveWire/WaveMap system in December 1996.
The WaveWire guide wire is undergoing manufacturing process improvements to
achieve production yields required to prepare for commercial-scale
manufacturing. Cardiometrics expects the product will be available for sale in
international markets as early as the second half of 1997. In addition,
Cardiometrics is developing a combination blood pressure sensing and blood flow
velocity device for enhanced functional testing capabilities. Like the FloWire
and the WaveWire, the combination device will be capable of replacing
conventional angioplasty guide wires with similar mechanical characteristics as
the FloWire.
 
     Cardiometrics is developing a 300 cm FloWire guide wire, an additional
version of the FloWire, in order to better support coronary stent placement
procedures. The longer version of the FloWire guide wire will allow the guide
wire to function as a guide for removing the initial balloon catheter and
introducing the stent catheter to complete the procedure, a so-called "over the
wire" exchange, without the need to extend the guide wire's length during the
procedure. The 300 cm FloWire is currently undergoing final design and
development and will then be submitted to the FDA for 510(k) review.
 
     The FloWire proprietary transducer design distinguishes itself from other
intravascular Doppler technologies in that it has a divergent beam pattern,
making it easier to sample the flow in the center of the vessel. Modifications
to this transducer design, increasing ease of signal acquisition and signal
stability and improving the product's manufacturability, received 510(k)
clearance in October 1996 and will replace the current tranducer sometime during
1997.
 
     Based on the same technology as the FloWire and FloMap, Cardiometrics has
developed products, the SmartWire Doppler guide wire and SmartMap ultrasound
instrument, which assess blood flow abnormalities in the cerebrovasculature for
the interventional neuroradiology market. Cardiometrics believes that this
information will assist in the diagnosis and treatment of cerebrovascular
blockages and the management of strokes, brain aneurysms, arteriovenous
malformations and other blood flow abnormalities. To date, only approximately
670 SmartWire guide wires have been sold for clinical research. Cardiometrics
expects that substantial clinical outcome studies demonstrating the efficacy of
the SmartWire/SmartMap system will likely be required to create significant for
Cardiometrics to significantly access this market and currently such studies are
not planned.
 
                                       10
<PAGE>   11
 
     In 1995 Cardiometrics introduced a primary 0.014" angioplasty guide wire
then market under the name AccuTrac. Based on customer response, Cardiometrics
no longer actively markets this product and is examining improvements in the
lubricious coating for the product. Cardiometrics expects that any such coating
improvements would also be utilized on Cardiometrics' other guide wire products.
 
  Clinical Outcome Studies
 
     Cardiometrics' research and development efforts include the sponsorship of
clinical outcome studies regarding Cardiometrics' products, such as the recently
completed Doppler Endpoints Balloon Angioplasty Trial Europe ("DEBATE") clinical
study. The DEBATE study, whose principal investigator was Professor Patrick
Serruys, M.D., Ph.D., of Erasmus University, Rotterdam, the Netherlands,
demonstrated that use of the FloWire guide wire (in conjunction with
quantitative coronary angiography) after balloon angioplasty can help identify
patients who are at high risk of restenosis. Based on the findings of the DEBATE
study, Cardiometrics initiated in 1996, among other studies, two major
clinical/economical outcome studies, DESTNI-CFR and DEBATE II, to validate the
findings of the DEBATE study in broader and larger patient populations. These
new studies are designed to demonstrate the benefits of physiologically guided
interventions using the FloWire, and to support the use of the FloWire in the
growing practice pattern of provisional stenting. Both studies feature clinical
and economic endpoints, and are being performed in many of the largest
interventional cardiology centers around the world. As is typical in medical
research, Cardiometrics funds the study costs of independent researchers and
clinicians.
 
COMPETITION
 
     Competition from products which help to diagnose and treat cardiovascular
disease is intense and may increase. In addition to functional stress testing,
competition currently comes from three sources: pressure devices, intravascular
ultrasound imaging and catheter based Doppler systems. As with stress testing
performed outside the cath lab, Cardiometrics does not view any of these other
three technologies as fulfilling the need for functional testing in the cath
lab, but they do compete for limited capital budgets and reimbursement funds and
for physician endorsement and adoption.
 
     When balloon angioplasty was first performed, the procedure was often
evaluated by the measurement of pressure drops across the lesion. However, the
measurements were often inaccurate due to the reduced diameter of the
angioplasty catheters. Furthermore, the physical presence of the catheter across
the lesion obstructed blood flow, thereby affecting the measurements.
Cardiometrics believes that although pressure devices can provide a valid
functional assessment of the degree of stenosis, when combined with the FloWire
derived information it can provide a more clinically useful functional
assessment of blood flow impairment.
 
     Cardiometrics is aware that other companies have developed or may be
developing pressure sensor-based guide wire systems, and Cardiometrics itself is
researching the possible application of its own technology to create a
combination pressure/flow assessment system. Radi Medical Systems, located in
Sweden, has been marketing a fiber optic version of a pressure guide wire
outside the U.S., but the product does not have the mechanical properties of a
primary guide wire for use in angioplasty and therefore is used mainly as a
research rather than clinical guide wire. Cardiometrics believes the
capabilities of this particular product are limited and does not consider it a
competing factor in the market. Cardiometrics believes that Scimed/Boston
Scientific and Schneider are developing and preparing to market guide wires with
pressure measurement capabilities. To the Company's knowledge, details regarding
these potential new product offerings are not yet publicly available.
 
     Intravascular ultrasound imaging ("IVUS"), like angiography, is an anatomic
tool. Therefore, from a clinical standpoint IVUS is complementary to, rather
than competitive with, functional angiometry. However, from a business
standpoint, IVUS is competitive with Cardiometrics' products since some
cardiologists may perform angioplasty without a functional test based only on
anatomical results and since both technologies could be competing for limited
hospital budgets, payor reimburse-
 
                                       11

ment funds and physician endorsement and adoption. The primary competitors in
this market include Cardiovascular Imaging Systems, Inc. ("CVIS"), a subsidiary
of Boston Scientific Corporation, EndoSonics Corporation and a joint marketing
relationship between Hewlett-Packard Co. and ACS/Guidant.
 
     Schneider, NuMed Inc. and Millar Instruments Inc. market or have marketed
catheters with distally-mounted Doppler ultrasound sensors. These larger
diameter products are limited to measuring coronary flow reserve proximal to the
lesion, because they are too large to cross the lesion without the device itself
interfering with flow. According to clinical data obtained using the FloWire
device, proximal measurements often do not show the flow limiting effects of a
lesion. Cardiometrics believes that distal measurements, which may be obtained
with the significantly smaller FloWire device, are necessary to accurately
assess impairment of flow. Cardiometrics believes its FloWire/FloMap system
competes favorably against these catheter based Doppler systems because of the
catheters' comparatively large size and less advanced hardware and software used
to obtain and interpret the signal.
 
PATENTS AND PROPRIETARY TECHNOLOGY
 
     Cardiometrics holds 17 issued patents in the United States associated with
the FloWire/FloMap and WaveWire/WaveMap systems and has eight U.S. patents
pending. Associated with the U.S. patents, there are a number of patents pending
in the major foreign markets. In addition to its patent positions, Cardiometrics
seeks to protect its proprietary information, especially manufacturing
processes, under applicable laws that protect trade secrets.
 
     The field of devices for the diagnosis and treatment of cardiovascular
disease is covered by a large and increasing number of patents and patent
applications, and there has been substantial litigation regarding patent and
intellectual property rights among medical device companies.
 
GOVERNMENT REGULATION
 
     Clinical testing, manufacture and sale of Cardiometrics' products are
subject to regulation by numerous governmental authorities, principally the FDA
and corresponding state and foreign regulatory agencies. Pursuant to the Federal
Food, Drug, and Cosmetic Act, and the regulations promulgated thereunder (the
"Act"), the FDA regulates the clinical testing, manufacture, labeling,
distribution and promotion of medical devices. Noncompliance with applicable
requirements can result in, among other things, fines, injunctions, civil
penalties, recall or seizure of products, total or partial suspension of
production, failure of the government to grant premarket clearance or premarket
approval for devices, withdrawal of marketing approvals and criminal
prosecution.
 
     In the U.S., medical devices are classified into one of three classes
(i.e., Class I, II, or III) on the basis of the controls deemed necessary by the
FDA to reasonably ensure their safety and effectiveness. Class I devices are
subject to general controls (e.g., labeling, premarket notification and
adherence to GMPs) and Class II devices are subject to general and special
controls (e.g., performance standards, postmarket surveillance, patient
registries and FDA guidelines). Generally, Class III devices are those which
must receive premarket approval by the FDA to ensure their safety and
effectiveness (e.g., life-sustaining, life-supporting and implantable devices,
or new devices which have been found not to be substantially equivalent to
legally marketed devices).
 
     Before a new device can be introduced to the market, the manufacturer
generally must obtain FDA clearance through either a 510(k) premarket
notification or a premarket approval application ("PMA"). A 510(k) clearance
will be granted if the submitted information establishes that the proposed
device is "substantially equivalent" to a legally marketed Class I or Class II
medical device, or to a preamendment Class III medical device for which the FDA
has not called for PMAs. The FDA has recently been requiring a more rigorous
demonstration of substantial equivalence than in the past, including requiring
clinical data more frequently. It generally takes from four to 12 months from
submission to obtain 510(k) clearance, but it may take longer. The FDA may
determine that a proposed device is not substantially equivalent to a legally
marketed device, or that additional data are
 
                                       12
<PAGE>   13
 
needed before a substantial equivalence determination can be made. A "not
substantially equivalent" determination, or a request for additional data, could
delay the market introduction of new products that fall into this category and
could have a material adverse effect on Cardiometrics' business, financial
condition and results of operations. For any of Cardiometrics' devices that are
cleared through the 510(k) process, modifications or enhancements that could
significantly affect the safety or effectiveness of the device or that
constitute a major change to the intended use of the device will require a new
510(k) submission. There can be no assurance that Cardiometrics will obtain
510(k) premarket clearance within the above time frames, if at all, for any of
the devices for which it may file a 510(k).
 
     If human clinical trials of a device are required, and the device presents
a "significant risk," the sponsor of the trial (usually the manufacturer or the
distributor of the device) will have to file an IDE application prior to
commencing human clinical trials. The IDE application must be supported by data,
typically including the results of animal and laboratory testing. If the IDE
application is approved, human clinical trials may begin at a specific number of
investigational sites with a specific number of patients, as approved by the
FDA. A PMA application must be filed if a proposed device is not eligible for
510(k) clearance. A PMA application must be supported by extensive data,
including preclinical and clinical trial data, to demonstrate the safety and
effectiveness of the device, as well as extensive manufacturing information.
Upon receipt of a PMA application, the FDA makes a threshold determination as to
whether the application is sufficiently fileable, and that it is complete to
permit a substantive review. If the FDA determines that the PMA application is
sufficiently complete to permit a substantive review, the FDA will accept the
application for filing.
 
     The FDA review of a PMA application can be expensive, lengthy and
uncertain. It generally takes one to two years from the date the PMA is accepted
for filing, but may take significantly longer. The FDA can ask for additional
information and generally will conduct a GMP inspection. Modifications to a
device that is the subject of an approved PMA, its labeling, or manufacturing
process may require approval by the FDA of PMA supplements or new PMAs.
Supplements to a PMA often require the submission of the same type of
information required for an initial PMA, except that the supplement is generally
limited to that information needed to support the proposed change from the
product covered by the original PMA.
 
     There can be no assurance that Cardiometrics will be able to obtain
necessary regulatory approvals or clearances on a timely basis or at all, and
delays in receipt of or failure to receive such approvals, the loss of
previously received approvals, or failure to comply with existing or future
regulatory requirements would have a material adverse effect on Cardiometrics'
business, financial condition and results of operations.
 
     Intravascular guide wires generally have been regulated as Class II devices
eligible for 510(k) clearance. The Company's current FloWire, Accutrac and
SmartWire product lines have all been cleared through the 510(k) process. In
December 1996, the Company submitted a 510(k) notification for the
WaveWire/WaveMap System and Wave Wire XT, which remains pending. The Company
believes that this submission adequately established that this product is
eligible for 510(k) clearance without clinical data. The Company believes the
300 cm FloWire also will be eligible for 510(k) clearance and plans to submit a
510(k) notification for the 300 cm FloWire once final design and development of
the product has been completed. However, there can be no assurance that FDA will
not require the Company to conduct a clinical study to support the Wave
Wire/Wave Map submission, or submissions regarding future products, which could
delay the market introduction of this product or future products, assuming
510(k) clearance can be obtained at all. There also can be no assurance that FDA
will not require that this product or future products undergo the more costly,
lengthy and uncertain PMA approval process.
 
     Labeling and promotion activities are subject to scrutiny by the FDA and,
in certain instances, by the Federal Trade Commission. The FDA actively enforces
regulations prohibiting marketing of products for unapproved uses. Cardiometrics
has recommended the use of its FloWire/FloMap system with drugs that induce
maximum hyperemia, such as adenosine, to measure the functional significance of
coronary artery lesions. Cardiometrics believes that its original 510(k)
clearance for the FloWire/FloMap system and subsequent clinical studies support
the use of the FloWire/FloMap system with these types of drugs in lieu of
conducting stress perfusion imaging, which involves the
 
                                       13
<PAGE>   14
 
injection of a radioactive substance such as radionuclide thallium, to measure
the impairment of blood flow to the myocardium. Adenosine has been approved by
the FDA as a coronary vasodilator for use as a pharmacological agent for stress
testing but not specifically with the FloWire/FloMap system. There can be no
assurance that the FDA will not require Cardiometrics to submit a new 510(k) or
PMA application for the FloWire/FloMap system for use with these drugs to
measure the functional significance of coronary artery lesions. If the FDA
requires such a submission, Cardiometrics could be prohibited from making claims
regarding the use of these drugs with the FloWire/FloMap system until such
submission were approved by the FDA. Such a prohibition could have a material
adverse effect upon Cardiometrics' business, financial condition or results of
operations. Cardiometrics has also made other modifications to its cleared
devices which Cardiometrics believes do not require the submission of new 510(k)
notices. There can be no assurance, however, that the FDA would agree with any
of Cardiometrics' determinations not to submit a new 510(k) notice for any of
these changes or would not require Cardiometrics to submit a new 510(k) notice
for any of the changes made to these devices. If the FDA requires Cardiometrics
to submit a new 510(k) notice for any device modification, Cardiometrics may be
prohibited from marketing the modified device until the 510(k) is cleared by the
FDA.
 
     Any products manufactured or distributed by Cardiometrics pursuant to the
FDA clearances or approvals are subject to pervasive and continuing regulation
by the FDA including record keeping requirements and reporting of adverse
experiences with the use of the device. Cardiometrics is subject to inspection
on a routine basis for compliance with the FDA's GMP regulations. These
regulations impose certain procedural and documentation requirements upon
Cardiometrics with respect to manufacturing and quality assurance activities.
The FDA has recently finalized changes to GMP requirements that, among other
thing, add requirements for purchasing and pre-production design controls and
maintenance of service records, and may therefore increase the cost of
compliance. Cardiometrics is also subject to FDA's radiological health
requirements which impose record keeping, reporting and safety requirements on
manufacturers of ultrasound products. A GMP inspection of Cardiometrics'
manufacturing facility was last completed in January 1995.
 
     Changes in existing requirements or adoption of new requirements could have
a material adverse effect on Cardiometrics' business, financial condition and
results of operations. Cardiometrics also is subject to numerous federal, state
and local laws relating to such matters as safe working conditions,
manufacturing practices, environmental protection, fire hazard control and
disposal of hazardous or potentially hazardous substances. There can be no
assurance that Cardiometrics will not be required to incur significant costs to
comply with such laws and regulations in the future or that such laws or
regulations will not have a material adverse effect upon Cardiometrics' ability
to do business.
 
     International sales are subject to foreign government regulation, the
requirements of which vary substantially from country to country. The time
required to obtain approval by a foreign country may be longer or shorter than
that required for FDA approval, and the requirements may differ. The
FloWire/FloMap system is approved in 17 countries in addition to the U.S.,
including all major European countries, Canada, Australia, New Zealand, and
Japan. The SmartWire/SmartMap system has been registered in Germany and France.
The WaveWire/WaveMap system is undergoing registration in Japan and Europe.
 
     In the European Community ("EC"), a device approval process is being
implemented to facilitate regulation. By June 1998, all devices will be required
to have a Conformite Europeene "CE" mark to be sold in the EC. To receive a CE
mark, a device must be evaluated by a Notified Body for conformity with the
European Medical Device Directive (93/42/EEC). Cardiometrics received the CE
mark approval for its intravascular medical devices (FloWire and SmartWire) in
January 1996 after successfully undergoing an ISO 9002 quality system assessment
by T.U.V. Product Service, a Munich, Germany-based Notified Body. Cardiometrics'
FloMap, FloMap II, and SmartMap instruments received the CE mark approval in May
1996 and its FloWire XT guide wire received the CE mark approval in October
1996. Cardiometrics has applied for CE marks for the WaveWire guide wire and
WaveMap instrument. As is the case with GMP inspections in the U.S.,
surveillance audits by Cardiometrics' notified body will continue in the EC on a
periodic basis after receipt of CE marks.
 
                                       14

     There can be no assurance that the necessary approvals for the use of
existing and new generations of Cardiometrics' products will be granted by the
FDA or other authorities on a timely basis or at all, and delays in receipt of
or failure to receive such approvals, or the loss of previously received
approvals, could result in the cessation of operations relating to a product or
group of products and could have a material adverse effect on the business,
financial condition and results of operations of Cardiometrics.
 
     In addition, in the U.S. there are federal and state laws which regulate
the financial relationships between manufacturers of medical devices, such as
Cardiometrics, and hospitals, physicians and other potential purchasers of
medical devices or sources of referral related to the purchase of medical
devices. The federal Medicare and Medicaid antikickback statute prohibits
financial relationships designed to induce the purchase, or arranging for or
recommending of the purchase, of items or services for which payment may be made
under Medicare, Medicaid, or other federally funded state health care programs.
Under current law, courts and the Office of Inspector General of the United
States Department of Health and Human Services have stated that the statute is
violated where even one purpose, as opposed to a primary or sole purpose, of the
arrangement is to induce purchases. The antikickback statute contains exceptions
for, among other things, properly reported discounts and compensation for bona
fide employees. In addition, federal regulations establish certain "safe
harbors" from liability under the antikickback statute, including further
refinements of the exceptions for discounts and employee compensation.
Cardiometrics' practices may not in all cases meet all of the criteria for a
safe harbor from antikickback law liability. Other provisions of state and
federal law provide civil and/or criminal penalties for presenting or causing to
be presented for payment claims that are false or fraudulent or for items or
services that were not provided as claimed. Because of the breadth of the
statutory provisions described above, it is possible that some of Cardiometrics'
business practices could be subject to scrutiny and challenge under one or more
such laws. Such a challenge could have a material adverse effect on the
business, financial condition and results of operations of Cardiometrics.
 
PRODUCT LIABILITY INSURANCE
 
     Medical device companies are subject to the risk of product liability and
other claims in the event that the use of their products results in personal
injury claims. Although Cardiometrics has not experienced any product liability
claims to date, any such claims could have an adverse effect on Cardiometrics.
Cardiometrics maintains liability insurance with per occurrence and an annual
aggregate maximum coverage of $5,000,000. There can be no assurance that product
liability or other claims will not exceed such insurance coverage limits or that
insurance will continue to be available on commercially acceptable terms, or at
all.
 
THIRD-PARTY REIMBURSEMENT
 
     Cardiometrics assists physicians and hospitals in seeking to obtain third
party reimbursement for professional fees and hospital costs in connection with
the use of the FloWire. In addition, Cardiometrics is working with managed care
organizations and capitated providers to have the FloWire incorporated into
practice guidelines. To date, use of the FloWire has received only limited
reimbursement from Medicare and other third party payors. In general, when
reimbursement has been denied, it has been denied because the payor has
considered functional angiometry to still be investigational or has concluded
that payment for the service is already bundled into payment that already has
been made to the physician for other cardiac procedures.
 
  Professional Fees
 
     In the U.S., physician payment for medical services is generally based on
the CPT coding system developed and maintained by the AMA. Because use of the
FloWire does not currently have its own CPT code, most physicians code
functional angiometry under a nonspecific cardiovascular code, which does not
assure reimbursement.
 
                                       15
<PAGE>   16
 
     Cardiometrics is also pursuing the creation of a separate CPT code for the
use of the FloWire. The AMA, which updates the CPT coding system annually, will
typically request input from the ACC on coding issues related to cardiology. In
past years, the ACC/AHA has advised the AMA that use of the FloWire was still
considered experimental. However, Cardiometrics believes that published data of
clinical outcomes involving the FloWire guide wire and the wider usage of the
FloWire guide wire should result in an ACC/AHA recommendation to the AMA
regarding a CPT code for functional angiometry; however, even with such ACC
recommendation there can be no assurance of the AMA's adoption of a CPT code.
Cardiometrics has undertaken a prospective, randomized clinical study comparing
the cost of using the FloWire to the cost of performing stress perfusion imaging
with thallium to determine the significance of intermediate coronary lesions
identified by angiography. Preliminary presentations of the results of the
Physiological Evaluation After Coronary Hyeremia ("PEACH") study indicate a
significant cost advantage for the FloWire. In the event a CPT code is assigned
by the AMA, the PEACH study should provide helpful guidance regarding the level
of payment to be made by third party payors under such a CPT code.
 
     However, even if the Company is successful in obtaining a new CPT code,
payees may still deny payment for use of the FloWire. With respect to Medicare,
in the absence of a national coverage determination by the Health Care Financing
Administration ("HCFA"), decisions concerning whether a particular item or
service is "reasonable and necessary," and therefore covered, is left to the
discretion of the various local Medicare carriers and fiscal intermediaries
("FIs") which administer the Medicare program. HCFA has not made a national
coverage determination concerning functional angiometry. Cardiometrics believes
that approximately 10 local carriers have thus far assessed the procedure. All
but two have denied coverage for the procedure on the basis that the device is
experimental or that the physician should not receive a separate fee for the use
of the device in addition to the fee received by the physician for the
angiography or angioplasty procedure. Other third-party payors have payment
policies that are similar to Medicare which may result in the denial of payment
for items or services that the payors determine are not medically necessary or
which preclude a separate payment for the angiography procedure with the FloWire
device. The scope of such payment policies and how they are applied varies
across payors.
 
     In 1995, Aetna Life Insurance Company ("Aetna"), the country's third
largest healthcare insurer, adopted a policy to provide coverage when the
FloWire is used consistent with published studies to determine the significance
of intermediate coronary lesions. Aetna joins General American Life Insurance
Co., a Medicare Carrier in Missouri, which had earlier adopted a formal policy
to cover this use of the FloWire. One other Medicare carrier will honor
professional claims for the FloWire pending a formal technology assessment which
is underway. Several other regional and national insurers are currently
conducting formal technology assessments of the FloWire.
 
  Hospital Claims
 
     In the United States, approximately 80% of angiography procedures, and
virtually all angioplasty procedures, are performed on an inpatient basis.
Medicare and many private insurers reimburse hospitals for inpatient services
under a prospective payment system based on DRGs. Under PPS, a hospital is paid
a fixed amount for each inpatient admission based on the DRG to which the
patient is assigned, which is in turn based on such factors as the patient's
diagnoses and surgical procedures. There is no established separate DRG for
functional angiometry. Accordingly, inpatient use of the FloWire will generally
fall under the DRGs for angiography or angioplasty, and there will be no
separate reimbursement for the cost of the FloWire. Similarly, Medicare and most
private insurers offer no separate hospital reimbursement for other stress
tests, such as stress perfusion imaging with thallium or stress
echocardiography, when they are performed during the same hospital stay as
angiography or angioplasty.
 
     At some centers, outpatient angiograms represent a significant portion of
all angiograms. Unlike with inpatient procedures, Medicare currently reimburses
covered hospital outpatient diagnostic procedures using a blended payment
methodology that is based in part on a fee schedule amount and in
 
                                       16
<PAGE>   17
 
part based on the hospital's reasonable costs of the procedure. Under this
payment methodology, assuming that the procedure is considered to be reasonable
and necessary, hospitals can be reimbursed by Medicare separately for the costs
associated with the FloWire on the same basis as they are reimbursed for other
diagnostic cardiac procedures performed on an outpatient basis. Private third-
party payors vary in their methodologies for reimbursing hospital outpatient
costs, but many payors employ methodologies that would allow for separate
reimbursement of the costs associated with functional angiometry. Cardiometrics
is working with hospital outpatient departments to assist them in obtaining
reimbursement from Medicare and other third-party payors. In addition, the
President's Budget Request for fiscal year 1998 calls for Congress to pass a
prospective payment system for hospital outpatient services. If Congress were to
enact such a provision, it might have an adverse impact on reimbursement for
this segment of the Company's market.
 
     Cardiometrics is unaware of whether Medicare or any third party payors
reimbursing hospitals for the costs of the FloWire have done so on the basis of
a formal coverage determination. Prudential Insurance Company informed
Cardiometrics in 1995 that, based on a formal technology assessment, they will
provide coverage for the FloWire in these situations.
 
  International Reimbursement
 
     In international markets, Cardiometrics works with its local distributors
to obtain necessary regulatory and reimbursement approvals. Cardiometrics
engages local investigators to perform regionally tailored clinical outcome
studies with a goal of obtaining positive review from local reimbursement
agencies. In Japan, the FloWire guide wire has been approved for reimbursement
by Japan's Ministry of Health since 1992.
 
EMPLOYEES
 
     As of February 15, 1997, Cardiometrics had 109 full-time employees, of whom
19 were involved in research and development, 55 in manufacturing, 22 in sales
and marketing and 13 in regulatory affairs, finance and administration.
Cardiometrics' employees are not covered by a collective bargaining agreement.
Cardiometrics believes its relationship with its employees is good.
 
RISK FACTORS THAT MAY AFFECT FUTURE RESULTS
 
     Cardiometrics operates in a highly competitive environment that involves a
number of risks, some of which are beyond Cardiometrics' control. The following
discussion highlights some of these risks. These risks should be read in
conjunction with the "Risk Factors" section included in the Company's
Registration Statement on Form S-1 as declared effective by the Securities and
Exchange Commission on November 1, 1995 (Registration No. 33-96690).
 
  Limited Market Acceptance; User Training
 
     The clinical use of Cardiometrics' FloWire/FloMap system in cardiovascular
applications is relatively new. The commercial success of the FloWire/FloMap
system will depend, in part, upon functional angiometry achieving broader
acceptance within the medical community as a clinically useful and
cost-effective procedure. There can be no assurance that functional angiometry
and the FloWire/FloMap system will achieve broader acceptance within the medical
community. Failure of functional angiometry and the FloWire/FloMap system to
achieve broader market acceptance would have a material adverse effect on
Cardiometrics' business, financial condition and results of operations.
 
     The FloWire/FloMap, WaveWire/WaveMap and SmartWire/SmartMap systems
introduce new technologies to intravascular diagnostic and interventional
procedures, and new users of these products must be trained in their proper use.
Accordingly, broader acceptance of Cardiometrics' principal products will
depend, in part, on the number of interventional cardiologists who become
trained in the use of the FloWire/FloMap system. However, there can be no
assurance of the ultimate number of such persons who will become trained or the
rate at which such training will occur, and the failure to train
 
                                       17
<PAGE>   18
 
sufficient numbers of users could have a material adverse effect on
Cardiometrics' business, financial condition and results of operations.
Cardiometrics' WaveWire/WaveMap system has yet to be commercially introduced and
currently there is only limited use of Cardiometrics' SmartWire/SmartMap system
for cerebrovascular applications. Accordingly, market acceptance of the
WaveWire/WaveMap and SmartWire/SmartMap systems and related user training
present the same and perhaps greater risks as those associated with the
FloWire/FloMap system.
 
  Acceptance of Cardiometrics' Products Depends Upon Results of Clinical Studies
  and Acceptance by Medical Community
 
     Clinical studies of the FloWire are in various stages of completion, and
further clinical studies of the FloWire and Cardiometrics' other products are
expected to be conducted in the future. Clinical studies of Cardiometrics'
products which result in unfavorable or inconclusive findings could have a
material adverse effect on Cardiometrics' business, financial condition and
results of operations. In addition, there can be no assurance that favorable
results derived from clinical studies will be conclusive enough for the medical
community and payors to react positively to such findings and change practice
patterns and reimbursement decisions based on such findings.
 
  History of Losses; Likelihood of Additional Losses; Limited Operating History
 
     Cardiometrics has incurred net losses since its incorporation in October
1985. As of December 31, 1996, Cardiometrics' accumulated deficit was $34.0
million, $24.2 million of which has been incurred since Cardiometrics
restructured its operations in 1990. Cardiometrics expects to incur additional
losses until sufficient sales of its FloWire guide wires are achieved.
Cardiometrics did not begin shipping products in volume until 1991.
Cardiometrics' limited operating history makes the prediction of future
operating results difficult or impossible to make. There can be no assurance
that Cardiometrics will be able to achieve significant growth in sales or
generate profits in the future and failure to do so would have a material
adverse effect on Cardiometrics' business, financial condition and results of
operations.
 
  Uncertainties Relating to Merger
 
     There can be no assurance that the pending Merger will be consummated or
that if consummated that it will result in any operating or strategic benefits.
In addition, in connection with the Reorganization Agreement entered into with
EndoSonics and the pending Merger, Cardiometrics has incurred and expects to
incur substantial direct transaction costs, including investment banking, legal,
accounting, registration and printing fees. These transaction costs will have a
short-term adverse effect upon the financial results of Cardiometrics.
 
  Dependence on Third Party Reimbursement
 
     In the U.S., demand for Cardiometrics' products is dependent in part on the
reimbursement policies of various public and private third-party payors.
Physicians generally are paid for medical services based upon the Current
Procedural Terminology ("CPT") coding system developed and maintained by the
American Medical Association ("AMA"). Currently, there is no CPT code
specifically for functional angiometry, and physicians using the FloWire are not
assured payment from third party payors for their professional services in
connection with the FloWire.
 
     Under the Medicare statute, Medicare generally will not cover items or
services that are "not reasonable or necessary" for the diagnosis or treatment
of illness or injury. The Health Care Financing Administration ("HCFA"), has not
made a national coverage determination concerning functional angiometry. All but
two local Medicare carriers and fiscal intermediaries ("FIs") which have
assessed the procedure have denied coverage for the procedure on the basis that
the device is experimental or that the physician should not receive a separate
fee for the use of the device in addition to the fee received by the physician
for the angiography or angioplasty procedure. There is no assurance that the
 
                                       18
<PAGE>   19
 
Medicare carriers and FIs will conclude that functional angiometry should be
covered by Medicare and that separate reimbursement should be made to physicians
for functional angiometry in addition to the reimbursement they receive for
other cardiac procedures. Other third-party payors have payment policies that
are similar to Medicare which may result in the denial of payment for the
FloWire or services related to the FloWire.
 
     Medicare and many private insurers reimburse hospital inpatient services
through a prospective payment system ("PPS") based on Diagnostic Related Groups
("DRGs"). Under PPS, a hospital is paid a fixed amount for each inpatient
admission based on the DRG to which the patient is assigned, which is based on
such factors as the patient's diagnoses and surgical procedures. There is no
established separate DRG for functional angiometry; accordingly, performance of
functional angiometry on an inpatient basis during angiography and angioplasty
typically will be reimbursed under the DRGs for such procedures, but would not
result in separate reimbursement for the cost of the FloWire guide wire.
 
     Internationally, there are various national and regional reimbursement
systems and policies which influence demand for Cardiometrics' products.
Accordingly, broader international demand for Cardiometrics' products will
depend, in part, on Cardiometrics' ability to develop and implement specific
reimbursement strategies for each nation or region where a potential market for
Cardiometrics' products exists.
 
     There can be no assurance that separate reimbursement for the FloWire will
ever be available under an existing or newly established DRG or CPT code, or
that future reimbursement policies of payors will not adversely affect
Cardiometrics' ability to sell the FloWire on a profitable basis in the U.S. or
abroad. The failure of hospitals and other users of Cardiometrics' products to
obtain sufficient reimbursement from third party payors or adverse changes in
the reimbursement policies of government and private third party payors toward
procedures employing Cardiometrics' products could have a material adverse
effect on Cardiometrics' business, financial condition and results of
operations.
 
  Uncertainty of Health Care Cost Constraints
 
     There are widespread efforts to control health care costs in the U.S. and
worldwide. Cardiometrics believes that government and private efforts to contain
or reduce health care costs are likely to continue. These trends may lead
third-party payors to decline or limit reimbursement for Cardiometrics'
products, which could negatively impact the pricing and profitability of, or
demand for, Cardiometrics' products. There can be no assurance that legislative
or regulatory health care reform, if enacted, would not result in a material
adverse impact on the business, financial condition or results of operations on
Cardiometrics.
 
  Reliance on Patents and Proprietary Technology; Risk of Patent Infringement
  and Litigation
 
     Cardiometrics holds 17 issued U.S. patents associated with its principal
products and has eight pending U.S. patent applications. Cardiometrics has also
filed a number of counterpart patent applications internationally. There can be
no assurance, however, that Cardiometrics' patent applications will issue as
patents or that any issued patents will provide competitive advantages for
Cardiometrics' products or will not be successfully challenged or circumvented
by competitors. The field of devices for the diagnosis and treatment of
cardiovascular disease is covered by a large and increasing number of patents
and patent applications. There can be no assurance that Cardiometrics' products
do not infringe upon the patent rights and other intellectual property rights of
others. Since patent applications in the U.S. are maintained in secrecy until
patents issue, and since publications of discoveries in the scientific or patent
literature tend to lag behind actual discoveries by several months,
Cardiometrics cannot be certain that it was the first creator of inventions
covered by pending patent applications or that it was the first to file patent
applications for such inventions.
 
     There has been substantial litigation regarding the infringement of patent,
trademark and other intellectual property rights among medical device companies.
In the future, Cardiometrics may find
 
                                       19
<PAGE>   20
 
such litigation necessary to enforce patents issued to Cardiometrics, to protect
trade secrets, trademarks and other intellectual property rights held by
Cardiometrics, to defend Cardiometrics against claims of infringement of the
rights of others or to determine the scope and validity of the proprietary
rights of others. Any such litigation could involve significant expense to
Cardiometrics and could divert the attention of Cardiometrics' technical and
management personnel. Moreover, agreements with a number of its distributors
require that Cardiometrics indemnify such distributors against costs, expenses
and liabilities relating to such litigation and, despite these obligations of
Cardiometrics, distributors may decide to reduce or end their selling efforts
until an infringement dispute is resolved or settled. Cardiometrics may be
required to participate in interference proceedings declared by the U.S. Patent
and Trademark Office to determine the priority of inventions, which could also
result in substantial cost to Cardiometrics. Adverse determinations in
connection with such litigation or proceedings could subject Cardiometrics to
significant liabilities, prevent Cardiometrics from manufacturing or selling its
products or result in distributors becoming unwilling to distribute
Cardiometrics' products. In such events, Cardiometrics may seek licenses from
third parties or attempt to redesign its products or processes to avoid
infringement; however, there can be no assurance that such licenses would be
available or, if available, would be on terms acceptable to Cardiometrics or
that Cardiometrics would be successful in any attempt to redesign its products
or processes to avoid infringement.
 
     Cardiometrics is dependent upon its proprietary technology and seeks to
protect such technology through a combination of confidentiality agreements and
trade secrets, in addition to patents and patent applications covering various
aspects of its existing and future technology. In connection with Cardiometrics'
trade secrets and confidentiality agreements, there can be no assurance that the
obligation to maintain the confidentiality of trade secrets or other proprietary
information of Cardiometrics will not be breached by employees or consultants or
that Cardiometrics' trade secrets or proprietary technology will not otherwise
become known or be independently developed by competitors in such a manner that
Cardiometrics has no practical recourse.
 
  International Sales; Currency Fluctuations
 
     Cardiometrics sells its products outside of the U.S. through 20
international distributors. International sales represented approximately 72%,
76% and 75% of Cardiometrics' total sales in 1994, 1995 and 1996, respectively.
Cardiometrics believes that international sales will continue to represent a
significant portion of its sales and play a significant role in its future
growth and success. Accordingly, if a significant number of its international
distributors were to experience financial difficulties, or otherwise become
unable or unwilling to promote, sell or pay for Cardiometrics' products,
Cardiometrics' business, financial condition, and results of operations could be
adversely affected. Although Cardiometrics' sales to international distributors
are denominated in U.S. dollars, its international business may be affected by
changes in demand resulting from fluctuations in currency exchange rates.
Additional risks inherent in Cardiometrics' international business activities
include the burdens of monitoring and complying with a wide variety of foreign
laws, regulatory requirements and reimbursement practices, costs of localizing
products for foreign countries, lack of acceptance of localized products in
foreign countries, longer accounts receivable payment cycles, difficulties in
collecting payment, difficulties in managing international operations and
potentially reduced protection for intellectual property. There can be no
assurance that such factors will not have a material adverse effect on
Cardiometrics' future international sales and, consequently, Cardiometrics'
business, financial condition or results of operations.
 
  Concentration of Sales in Japan
 
     Sales to its distributor for Japan represented approximately 34%, 37% and
41% of Cardiometrics' total sales in 1994, 1995 and 1996, respectively.
Cardiometrics expects that sales in Japan will continue to represent a
significant portion of its sales. Cardiometrics believes that its sales in Japan
are due, in part, to the official reimbursement status granted to the
FloWire/FloMap system by Japan's Ministry of Health in 1992. Regulatory
approvals for the FloWire/FloMap system were obtained in the name of
 
                                       20
<PAGE>   21
 
Cardiometrics' distributor for Japan, who has agreed to assign the approvals to
Cardiometrics upon termination of the distribution agreement, which under its
current terms will expire in 1999, and upon reimbursement by Cardiometrics of
reasonable expenses incurred by the distributor in obtaining the official
reimbursement status and other government approvals in connection with the
FloWire/FloMap system. Cardiometrics' sales in Japan could decline materially as
a result of a change in the official reimbursement status of the FloWire/FloMap
system or difficulties in obtaining the assignment of regulatory approvals upon
termination of the existing exclusive distribution agreement for Japan, as well
as by factors generally influencing international sales. There can be no
assurances that such developments will not occur. A material decline in
Cardiometrics' sales in Japan would have a material adverse effect on
Cardiometrics' business, financial condition and results of operations.
 
  Risk of Technological Obsolescence
 
     The interventional cardiology market is characterized by rapid
technological innovation and change. Many companies are engaged in research and
development of new devices and alternative methods to diagnose and treat
coronary artery disease, including new or improved medical devices and
pharmaceutical products. Cardiometrics' products could be rendered obsolete as a
result of future innovations.
 
  Dependence on Limited Number of Products; Risk of New Product Development
 
     Virtually all of Cardiometrics' sales have been derived from sales of the
FloWire/FloMap system. Although additional products are being developed, such as
the WaveWire/WaveMap system, such development efforts are subject to significant
risks, including the risks of obtaining regulatory approvals and manufacturing
new products in commercial volumes. There can be no assurance that
Cardiometrics' development efforts will be successful or, even if successful,
that resulting products would receive market acceptance, generate significant
sales or result in gross profits. Accordingly, Cardiometrics believes that the
FloWire/FloMap system will continue to account for a significant portion of
Cardiometrics' total revenue for at least the foreseeable future. Cardiometrics'
future operating results, particularly in the near term, are significantly
dependent upon market acceptance of the FloWire/FloMap system and the successful
introduction of the WaveWire/WaveMap system. Because virtually all of
Cardiometrics' sales are derived from the FloWire/FloMap system, failure to
achieve broader market acceptance of the FloWire/FloMap system as a result of
competition, technological change or other factors and the failure to
successfully market any new or enhanced products would have a material adverse
effect on the business, operating results and financial condition of
Cardiometrics.
 
  Competition
 
     Competition from products which help to diagnose and treat cardiovascular
disease is intense and may increase. Stress testing systems, intravascular
pressure devices, intravascular ultrasound imaging devices and catheter based
Doppler systems are currently being used in diagnosing and assessing
cardiovascular disease and compete directly or indirectly with the
FloWire/FloMap system and the WaveWire/WaveMap system under development. Many of
the companies selling products which employ such technologies have developed an
installed base significantly larger than Cardiometrics' installed base. The high
purchase prices paid for equipment associated with these technologies may make
current users of products employing such technologies reluctant to abandon
investments in such equipment to use the FloWire/FloMap system. Moreover, there
can be no assurance that existing and future competitors of Cardiometrics will
not modify existing products or develop new products that compete with
Cardiometrics' FloWire/FloMap system and the WaveWire/WaveMap system.
 
     Companies whose products employ competing technologies or who may develop
products which could directly compete with Cardiometrics' products may
ultimately offer products that are more effective or less costly than those
developed and marketed by Cardiometrics. Many of Cardiometrics' competitors and
potential competitors have substantially greater financial, manufacturing,
marketing,
 
                                       21
<PAGE>   22
 
distribution and technical resources than Cardiometrics and are engaged in
research and development of new devices and alternative methods to diagnose,
treat and prevent cardiovascular disease, including new or improved angioplasty,
atherectomy and other devices and pharmaceutical agents. Introduction of such
devices and alternative methods could hinder Cardiometrics' ability to compete
effectively and could have a material adverse effect on its business, financial
condition and results of operations.
 
  Quarterly Fluctuations in Operating Results
 
     Results of operations have varied and may continue to fluctuate
significantly from quarter to quarter and will depend upon numerous factors,
including (i) timing of regulatory approvals, (ii) new product introductions,
(iii) competition, (iv) sales under distributor agreements, (v) Cardiometrics'
ability to manufacture its products efficiently, (vi) timing of research and
development expenses, including clinical outcome studies, and (vii) seasonal
factors in markets, particularly Europe. Since typically there are fewer
elective interventional procedures during the summer months due to vacation
schedules of patients and health care providers, especially in Europe, sales of
Cardiometrics' products frequently slow during July and August. Cardiometrics
expects that its quarterly operating results will fluctuate in the future as a
result of these and other factors. Due to such past and future quarterly
fluctuations in operating results, quarter-to-quarter comparisons of
Cardiometrics' operating results are not necessarily meaningful and should not
be relied upon as indicators of likely future performance or annual operating
results.
 
  FDA and Other Government Regulation
 
     The manufacturing and marketing of Cardiometrics' products are subject to
extensive and rigorous regulation by numerous governmental authorities,
principally the U.S. Food and Drug Administration (the "FDA") and corresponding
state and foreign agencies. The regulatory process is lengthy, expensive and
uncertain. Prior to commercial sale in the U.S., most medical devices, including
Cardiometrics' products under development, must be cleared or approved by the
FDA. Product clearances and approvals can be withdrawn for failure to comply
with regulatory standards or the occurrence of unforeseen problems following
initial marketing. Foreign governments also have review processes for new
products which present many of the same risks. There can be no assurance that
Cardiometrics will be able to obtain necessary regulatory clearances or
approvals on a timely basis, if at all, for any of its products under
development, and delays in receipt of or failure to receive such clearances or
approvals, the loss of previously received clearances or approvals, or failure
to comply with existing or future regulatory requirements could have a material
adverse effect on Cardiometrics' business, financial condition and results of
operations. Cardiometrics also is subject to routine inspection by the FDA and
certain foreign and state agencies, such as the Food and Drug Branch of the
California Department of Health Services, for compliance with Good Manufacturing
Practices ("GMP") requirements and other applicable regulations. Noncompliance
with applicable regulatory requirements can result in, among other things,
fines, injunctions, civil penalties, recall or seizure of products, total or
partial suspension of production, failure of the government to grant premarket
clearance or premarket approval for devices, withdrawal of marketing approvals,
and criminal prosecution.
 
     Cardiometrics believes that its success will be significantly dependent
upon commercial sales of improved versions and new applications of its guide
wires. Cardiometrics will not be able to market these new products in the U.S.
unless and until Cardiometrics obtains 510(k) premarket clearance or premarket
approval ("PMA") from the FDA. In general, it takes from four to 12 months from
submission to obtain 510(k) premarket clearance, but it may take longer. The FDA
review of a PMA application generally takes one to two years from the date the
PMA application is accepted for filing, but also may take significantly longer.
The review time is often significantly extended by the FDA asking for more
information, including additional clinical trials, or clarification of
information already provided. A number of devices for which FDA approval has
been sought by other companies have never been approved for marketing. The time
required to obtain approval from a foreign country may be
 
                                       22
<PAGE>   23
 
longer or shorter than that required for FDA approval, and the requirements may
differ. In the near future, all devices will be required to have a "CE Mark" to
be sold in the European Community ("EC"). Cardiometrics recently obtained the CE
Mark for its FloWire and SmartWire products, but there can be no assurance that
CE Marks will be obtained for Cardiometrics' other or future products.
 
     Intravascular guide wires generally have been regulated as Class II devices
eligible for 510(k) clearance. Cardiometrics' current FloWire, AccuTrac and
SmartWire product lines have all been cleared through the 510(k) process. In
December 1996, the Cardiometrics submitted a 510(k) notification for the
WaveWire/WaveMap System and Wave Wire XT, which remains pending. Cardiometrics
believes that this submission adequately establishes that this product is
eligible for 510(k) clearance without clinical data. The Company believes the
300 cm FloWire also will be eligible for 510(k) clearance and plans to submit a
510(k) notification for the 300 cm FloWire once final design and development of
the product has been completed. However, there can be no assurance that FDA will
not require Cardiometrics to conduct a clinical study to support the
WaveWire/WaveMap submission, or submissions regarding future products, which
could delay the market introduction of this product or future products, assuming
510(k) clearance can be obtained at all. There also can be no assurance that FDA
will not require that this product or future products undergo the more costly,
lengthy and uncertain PMA approval process.
 
     Labeling and promotion activities are subject to scrutiny by the FDA and,
in certain instances, by the Federal Trade Commission. The FDA actively enforces
regulations prohibiting marketing of products for unapproved uses. Cardiometrics
has recommended the use of its FloWire/FloMap system with drugs that induce
maximum hyperemia (maximum blood flow), such as adenosine and papaverine, to
measure the functional significance of coronary artery lesions. There can be no
assurance that the FDA will not require Cardiometrics to submit a new 510(k) or
PMA application for the FloWire/FloMap system for use with these drugs to
measure the functional significance of coronary artery lesions. If the FDA
requires such a submission, Cardiometrics could be prohibited from making claims
regarding the use of these drugs with the FloWire/FloMap system until such
submission were approved by the FDA. Such a prohibition could have a material
adverse effect upon Cardiometrics' business, financial condition and results of
operations. Cardiometrics has also made other modifications to its cleared
devices which Cardiometrics believes do not require the submission of new 510(k)
notices. There can be no assurance, however, that the FDA would agree with any
of Cardiometrics' determinations and not require Cardiometrics to submit a new
510(k) notice for any of the changes made to these devices. If the FDA requires
Cardiometrics to submit a new 510(k) notice for any device modification,
Cardiometrics may be prohibited from marketing the modified device until the
510(k) is cleared by the FDA.
 
     In addition, in the U.S. there are federal and state antikickback laws
which regulate the financial relationships between manufacturers of medical
devices, such as Cardiometrics, and hospitals, physicians and other potential
purchasers of medical devices or sources of referral related to the purchase of
medical devices. Cardiometrics' practices may not in all cases meet all of the
criteria that have been established for a safe harbor from antikickback law
liability. Other provisions of state and federal law provide civil and/or
criminal penalties for presenting or causing to be presented for payment claims
that are false or fraudulent, or for items or services that were not provided as
claimed. Because of the breadth of such statutory provisions, it is possible
that some of Cardiometrics' business practices could be subject to scrutiny and
challenge under one or more such laws. Such a challenge could have a material
adverse effect on the business, financial condition and results of operations of
Cardiometrics.
 
  Dependence on Key Personnel
 
     Cardiometrics is dependent upon a limited number of key management, sales
and technical personnel. Cardiometrics' future success will depend in part upon
its ability to attract and retain highly qualified personnel. Cardiometrics
faces competition for such personnel from other companies, academic
institutions, government entities and other organizations. As a result, there
can be no assurance that Cardiometrics will be successful in hiring or retaining
qualified personnel. Cardiometrics carries key man insurance on each of its
officers. The employment agreements Cardiometrics has with its officers do not
provide for a specific term of employment. Therefore, officers and other key
personnel could leave the employ of Cardiometrics with little or no prior
notice. Loss of key personnel, especially
 
                                       23
<PAGE>   24
 
if such loss is without advance notice, or the inability to hire or retain
qualified personnel could have a material adverse effect on Cardiometrics'
business, financial condition and results of operations.
 
  Financial Exposure to Product Liability Claims
 
     Cardiometrics faces the risk of financial exposure to product liability
claims alleging that the use of Cardiometrics' products resulted in adverse
effects. Cardiometrics' products are often used in life-threatening situations
and are used in the brain, where there is a high risk of serious injury or
death. Such risks will exist even with respect to those products that have
received, or in the future may receive, regulatory approval for commercial sale.
Cardiometrics has taken and will continue to take what it believes are
appropriate precautions, including obtaining product liability insurance, to
minimize its exposure to liability. However, there can be no assurance that
Cardiometrics will avoid significant product liability claims and attendant
adverse publicity. Furthermore, there can be no assurance that Cardiometrics'
product liability insurance is adequate or that such insurance coverage will
remain available at acceptable costs. A successful claim brought against
Cardiometrics in excess of its insurance coverage could have a material adverse
effect on Cardiometrics' business, financial condition and results of
operations. Additionally, adverse product liability actions could negatively
affect market acceptance of Cardiometrics' products, third-party payors'
willingness to reimburse Cardiometrics' customers for use of Cardiometrics'
products, and Cardiometrics' ability to obtain and maintain regulatory approval
for its products.
 
  Limited Manufacturing Experience
 
     To date, Cardiometrics' manufacturing activities have consisted primarily
of manufacturing and assembling components of the FloWire/FloMap system and has
not yet manufactured the WaveWire/WaveMap system in commercial quantities. In
the event that sales of the FloWire/FloMap system increases substantially,
Cardiometrics would be required to increase its current production volumes and
in the event the WaveWire/WaveMap system achieves regulatory approval,
Cardiometrics plans to establish commercial scale manufacturing of such product.
There can be no assurance that current FloWire/FloMap manufacturing yields and
efficiencies will be maintained at increased production volumes or that adequate
WaveWire/WaveMap manufacturing yields and efficiencies will be achieved. Failure
to increase or establish production volumes in a timely or cost-effective manner
could have a material adverse effect on sales of Cardiometrics' products and on
Cardiometrics' business, financial condition and results of operations.
 
  Single Source Components and Processes
 
     Cardiometrics purchases certain components and processes from single-source
vendors, with whom Cardiometrics does not have long-term supply agreements. Any
supply interruption from these vendors would have a material adverse effect on
Cardiometrics' ability to manufacture its products until a new qualified source
of supply is obtained and, as a result, could have a material adverse effect on
Cardiometrics' business, financial condition and results of operations. While
Cardiometrics has a long-term contract with a single-source vendor of a critical
component of Cardiometrics' WaveWire guide wire; Cardiometrics is not aware of
an alternative source for such component. Accordingly, a disruption in the
operations of such vendor could have an adverse effect on Cardiometrics'
business, financial condition and results of operations.

ITEM 2.  PROPERTIES
 
     Cardiometrics leases two facilities in Mountain View, California with a
combined total of 20,000 square feet. The larger facility, encompassing 16,000
square feet, includes a 2,300 square foot Class 100,000 clean room as well as
guide wire manufacturing, inventory storage, laboratory and office space. The
smaller 4,000 square foot facility includes space for instrument manufacturing
and research and development. Cardiometrics' lease for the smaller facility
expires in March 1997, upon which Cardiometrics will occupy such facility
pursuant to a month-to-month tenancy. Cardiometrics believes its facilities will
be adequate through 1997.
 
ITEM 3.  LEGAL PROCEEDINGS
 
     On or about January 28, 1997, an alleged class action complaint was filed
by a Cardiometrics stockholder in the New Castle County Delaware Court of
Chancery. The complaint names Cardiometrics, EndoSonics, the directors of
Cardiometrics, two officers of Cardiometrics (one of whom is a director), and a
former director of Cardiometrics as defendants, and alleges, among other things,
that the individual defendants breached and are breaching their fiduciary and
other duties to plaintiff and other members of the purported class and that
EndoSonics knowingly aided and abetted such breaches. Plaintiff seeks (i)
injunctive relief to prevent the consummation of the Merger, (ii) if the Merger
is consummated, rescission of the Merger or payment of rescissory damages, (iii)
an accounting by the defendants, individually and severally, to members of the
class for their damages and defendants' profits by reason of the allegations
contained in the complaint, (iv) payment to the plaintiff of the costs and
expenses of the action, including reasonable counsel and expert fees, and (v)
any other and further relief as the Court deems just and proper. Cardiometrics
believes the complaint is without merit and intends to vigorously defend itself
and the named individual defendants against the allegations in the complaint.

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

GENERAL
 
     Cardiometrics was founded in 1985 to develop a catheter based system for
the continuous measurement of cardiac output utilizing Doppler ultrasound
techniques. In 1990, Cardiometrics discontinued development of its continuous
cardiac output measurement device due to Cardiometrics' assessment of the
product's inability to meet the performance expectations of the market. At this
time, Cardiometrics restructured its operations under new management to focus on
a new business strategy: the development and commercialization of the
FloWire/FloMap system.
 
     In 1991, Cardiometrics received FDA 510(k) clearance for its 0.018" FloWire
and began marketing and selling the FloWire primarily to clinical research sites
in the U.S., Europe and Japan. During 1992, the Japanese Ministry of Health
granted the FloWire/FloMap system official reimbursement status, resulting in
significant sales growth in Japan and in the U.S., and Cardiometrics received
FDA clearance for its 0.014" FloWire. In 1993, Cardiometrics substantially
increased its manufacturing capacity, including adding a second shift, to meet
significant back orders for the 0.014" FloWire product in Japan. After supplying
the FloWire devices to meet the back orders, Cardiometrics adjusted its
manufacturing capacity to one shift and reduced its manufacturing headcount.
 
     During 1993, increasing uncertainty concerning health care reform slowed
capital expenditures on medical equipment in the United States. In response,
Cardiometrics changed its U.S. marketing approach in 1994, from a capital
equipment focus to an emphasis on routine clinical usage of the FloWire and
resulting sales of disposable devices. In the U.S. market, Cardiometrics began
offering hospitals the option to obtain the use of the FloMap in exchange for a
commitment to purchase a minimum number of FloWire devices per month for a
period of one to two years. This change was accompanied by a reduction and
reorganization of the U.S. sales force and resulted in a decrease in FloMap
sales.
 
     In 1994 Cardiometrics continued to invest in clinical outcome studies and
to develop its sales and marketing capabilities. In August 1995, Cardiometrics
introduced its FloMap II product, a compact version of the FloMap, for
installation in each cath lab room, at a lower price point than the portable but
freestanding FloMap.
 
     In November 1995, Cardiometrics completed an initial public offering of
2,200,000 shares of common stock with net proceeds of $17.6 million.
 
     Based on the outcome of the DEBATE clinical study presented in early 1996,
Cardiometrics began to focus its sales and marketing efforts on the use of the
FloWire to assess post-procedural results of angioplasty. To support this new
focus, two new clinical studies, DESTINI-CFR and DEBATE II, were started in the
second half of 1996. In December 1996, Cardiometrics filed a FDA 510(k)
premarket notification for the WaveWire/WaveMap pressure system, and its first
clinical use was demonstrated in Europe during the same month.
 
     On January 26, 1997, Cardiometrics, EndoSonics Corporation, a Delaware
Corporation ("EndoSonics"), and River Acquisition Corporation, a Delaware
Corporation and a wholly owned subsidiary of EndoSonics ("Merger Sub"), entered
into an Agreement and Plan of Reorganization (the "Reorganization Agreement"),
pursuant to which Merger Sub will be merged with and into Cardiometrics (the
"Merger"), with Cardiometrics surviving the Merger and becoming a wholly owned
subsidiary of EndoSonics. The consummation of the Merger is subject, among other
things, to the
 
                                       29
<PAGE>   30
 
approval of the Merger by the stockholders of Cardiometrics, at a stockholders
meeting currently expected to be held in May 1997 and the satisfaction of
certain other closing conditions.
 
     Cardiometrics has not been profitable since inception and, as of December
31, 1996, had an accumulated deficit of $34.0 million, $24.2 million of which
has been incurred since Cardiometrics restructured its operations in 1990.
Further growth in the sales volume of Cardiometrics' products and the resulting
gross profit will be needed to offset future investments in research and
development, principally clinical outcome studies, and selling, general and
administrative expenses.

</TABLE>
 
  Year Ended December 31, 1996 Compared to Year Ended December 31, 1995
 
     Sales.  Sales increased 26% during the period ended December 31, 1996 over
the period ended December 31, 1995 to $14,003,000 from $11,112,000. This
increase was primarily the result of an increase in sales of FloWire units,
primarily in Japan and the U.S., and, to a lesser extent, an increase in the
average realized selling price of FloWire units. These increases were partially
offset by decreases in sales of AccuTrac, SmartMap and SmartWire units.
 
     Cost of sales.  Cost of sales increased 10% during the period ended
December 31, 1996 over the period ended December 31, 1995 to $5,214,000 from
$4,730,000. Cost of sales as a percentage of sales decreased to 37% in the
period ended December 31, 1996 from 43% in the period ended December 31, 1995.
This decrease was the result of a greater percentage of FloWire sales, which
carry higher gross margins than instrument sales. The decrease was also the
result of unit manufacturing cost reductions for FloWire devices. These cost
reductions were achieved through lower manufacturing overhead cost per unit due
to increased volumes.
 
     Research and development.  Research and development expenses increased 45%
for the period ended December 31, 1996 over the period ended December 31, 1995
to $3,279,000 from $2,259,000. As a percentage of sales, research and
development expenses increased to 24% in the period ending December 31, 1996
from 20% in the period ended December 31, 1995. The increase was primarily the
result of increased spending on clinical studies, which Cardiometrics includes
in research and development expenses. These studies include DESTINI-CFR and
DEBATE II, which were new studies commenced in 1996 and which will continue in
1997 and 1998. The increase in research and development was also the result of
and increased spending for personnel and outside services related to new product
development. Cardiometrics plans to continue its expenditures in research and
development, including additional clinical studies.

     Selling, general and administrative.  Selling, general and administrative
expenses increased 33% in the period ended December 31, 1996 over the period
ended December 31, 1995 to $8,682,000 from $6,549,000. As a percentage of sales,
selling, general and administrative expenses increased to 62% in the period
ending December 31, 1996 from 59% in the period ended December 31, 1995. This
increase relates primarily to expenses associated with increased sales volumes,
marketing programs, external corporate reporting and increased staffing and
associated expenses.
 
  Year Ended December 31, 1995 Compared to Year Ended December 31, 1994
 
     Sales.  Sales increased 23% during the period ended December 31, 1995 over
the period ended December 31, 1994 to $11,112,000 from $9,006,000. This was
primarily the result of an increase in the average realized selling price for
the FloWire units and, to a lesser extent, an increase in sales volume of
FloWire units and to the introduction of the AccuTrac angioplasty guide wire.
 
     Cost of sales.  Cost of sales increased 12% during the period ended
December 31, 1995 over the period ended December 31, 1994 to $4,730,000 from
$4,213,000. Cost of sales as a percentage of sales decreased to 43% in the
period ended December 31, 1995 from 47% in the period ended December 31, 1994.
This decrease is principally the result of unit manufacturing cost reductions
for FloWire devices. These cost reductions were achieved through lower
manufacturing overhead cost per unit due to increased volumes and manufacturing
efficiencies, such as Just In Time techniques to reduce throughput time,
improved yields, reduced scrap costs and out-sourcing of non-proprietary
fabrication and assembly processes.
 
     Research and development.  Research and development expenses decreased 24%
for the period ended December 31, 1995 over the period ended December 31, 1994
to $2,259,000 from $2,960,000. As a percentage of sales, research and
development expenses decreased to 20% in the period ending December 31, 1995
from 33% in the period ended December 31, 1994. The decrease was primarily due
to a temporary reduction in spending on clinical studies, which Cardiometrics
includes in research and development expenses, as a result of the completion of
patient recruitment for major studies started in 1993 and 1994.
 
     Selling, general and administrative.  Selling, general and administrative
expenses increased 22% in the period ended December 31, 1995 over the period
ended December 31, 1994 to $6,549,000 from $5,375,000. As a percentage of sales,
selling, general and administrative expenses increased 1%. The increase in
selling and marketing expenses relates primarily to increased sales volume and
additional sales and marketing programs commenced in late 1994 and early 1995.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Since inception, Cardiometrics has financed its operations primarily
through the private sales of equity securities, raising approximately $38.5
million, and through an initial public offering in November 1995 with net
proceeds of approximately $17.6 million. In addition, Cardiometrics has financed
a substantial portion of its capital equipment requirements to date through
notes payable issued under a $1.5 million equipment loan and security agreement.
 
     In 1996, 1995 and 1994, Cardiometrics' cash used in operations was
$2,761,000, $2,717,000 and $3,134,000, respectively. The decrease in cash used
in operations from 1994 to 1996 was primarily due to increases in product sales
and gross margin improvements which were partially offset by increases in net
inventory and accounts receivable.
 
     At December 31, 1996, Cardiometrics' principal sources of liquidity
included an aggregate of $17,439,000 in cash, cash equivalents and short term
investments. Cardiometrics expects to incur substantial additional costs,
including costs related to sales and marketing and research and development,
including additional clinical outcome studies and the purchase of capital
equipment. Cardiometrics believes that the remaining net proceeds of the
November 1995 initial public offering will provide sufficient funds for
Cardiometrics' anticipated funding requirements through at least 1997 and for
the foreseeable future. However, there can be no assurance that Cardiometrics
will not require additional financing, or that if required, such financing will
be available on terms acceptable to Cardiometrics.

                         NOTES TO FINANCIAL STATEMENTS
 
1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Description of Business and Basis of Presentation
 
     Cardiometrics, Inc. (the "Company"), a Delaware corporation, develops,
manufactures and markets intravascular medical devices to measure blood flow
impairment caused by coronary artery and vascular disease.
 
     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. Certain
prior period amounts may have been adjusted for consistency and presentation
purposes.
 
  Reincorporation
 
     In August 1995, the board of directors of the Company authorized the
reincorporation of the Company in the State of Delaware and a 1-for-3.2 reverse
stock split, in which 3.2 shares of common stock were exchanged for one share of
common stock. Following stockholder approval, the reincorporation was completed
on October 25, 1995.
 
     Upon the reincorporation, the Company became authorized to issue 5,000,000
shares of $0.01 par value preferred stock and 15,000,000 shares of $0.01 par
value common stock. All par value, share and per share amounts, as well as the
dividend and liquidation preferences for preferred stock, included in the
accompanying financial statements, have been retroactively adjusted to reflect
the reverse stock split and the Company's reincorporation in Delaware.
 
  Cash, Cash Equivalents and Short Term Investments
 
     The Company invests its excess cash in investment grade, short term,
interest bearing investments. Cash equivalents and short term investments
consist of investment grade corporate obligations and money market funds. The
Company considers highly liquid investments with original maturities of less
than three months to be cash equivalents.
 
     The Company's marketable securities are sold if cash is needed and,
therefore, are considered "available-for-sale." At December 31, 1996 and 1995,
the amortized cost of marketable securities approximated market value. Realized
gains and losses on marketable securities were insignificant during 1994, 1995
and 1996. The weighted average maturity on the short-term investments held as of
December 31, 1996 does not exceed twelve months. The following table details the
estimated fair market value of available-for-sale securities (in thousands).

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     The Company also held $2,504,000 and $1,000,000 in certificates of deposit
as of December 31, 1996 and 1995 respectively. The estimated fair market value
amounts have been determined by the Company using available market information.
 
  Inventories
 
     Inventories are stated at the lower of cost or market. Cost is based on the
first-in, first-out method and is determined using standard costs which
approximate actual cost.
 
  Property and Equipment
 
     Equipment, including leasehold improvements, is recorded at cost. Equipment
is depreciated using the straight-line method over the estimated useful lives of
the assets, generally three to five years. Leasehold improvements are amortized
using the straight-line method over the shorter of the life of the related asset
or the term of the lease.
 
  Concentration of Credit Risk
 
     The Company sells its products primarily to members of the health services
industry and distributors and generally requires no collateral. The Company
maintains reserves for potential credit losses, and to date such losses have
been within management's expectations.
 
  Revenue Recognition
 
     The Company recognizes revenue from the sale of its products when the
products are shipped to its customers.
 
  Net Loss Per Share
 
     Except as noted below, historical net loss per share is computed using the
weighted average number of shares of common stock outstanding. Common equivalent
shares from stock options and warrants are excluded from the computation as
their effect is antidilutive, except that, pursuant to the Securities and
Exchange Commission Staff Accounting Bulletins, common and common equivalent
shares issued at prices substantially below the public offering price during the
12-month period prior to the initial filing of the initial public offering have
been included in the calculation as if they were outstanding for all periods
through November 3, 1995 (using the treasury stock method). The historical net
loss per share information is calculated below:

  Stock Based Compensation
 
     In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards ("SFAS") No. 123, "Accounting for Stock-Based
Compensation," which encourages, but does not require, companies to record
compensation expense for stock-based employee

compensation plans at fair value. The Company has chosen to continue to apply
Accounting Principles Board ("APB") No. 25, "Accounting for Stock Issued to
Employees," and related interpretations in accounting for its stock based plans
and, accordingly, does not recognize compensation expense related to employees
under its stock option plans for options granted to employees with an exercise
price equal to the fair value of the underlying stock on the grant date or under
its stock purchase plan. Note 5 contains a summary of the pro forma effects to
reported net loss and loss per share for 1996 and 1995 if the Company had
elected to recognize compensation expense based on the fair value of the options
granted as described by SFAS 123.

  1985 and 1995 Employee Stock Option Plans
 
     In October 1985, the Company adopted an Employee Stock Option and Purchase
Plan (the "1985 Plan"). In August 1995, the Company adopted a 1995 Stock Option
Plan (the "1995 Plan"). Under the 1985 Plan and 1995 Plan (collectively the
"Predecessor Plans"), employees, directors or consultants could be granted, at
the discretion of the board of directors, options (incentive stock and/or
nonqualified stock options) to purchase common stock at the then current fair
market value or discounts to their current fair market value, respectively. All
outstanding options and shares available for grant under the Predecessor Plans
were transferred to the 1995 Stock Incentive Plan (see below).
 
  1995 Stock Incentive Plan
 
     The Company's 1995 Stock Incentive Plan (the "Plan") succeeded the
Predecessor Plans. The Plan was adopted by the Board of Directors on September
5, 1995 and approved by the stockholders in October 1995. There are 1,399,914
shares of common stock authorized for issuance under the Plan.

This share reserve is comprised of the shares which remained available for
issuance under the Predecessor Plans, including the shares subject to
outstanding options thereunder. Outstanding options under the Predecessor Plans
were incorporated into the Plan and no further option grants will be made under
the Predecessor Plans. Options granted before October 15, 1995 were immediately
exercisable upon grant, and, options granted after October 15, 1995 were
exercisable upon vesting, which is generally ratable over a four year period.
 
     The Plan is divided into four separate components: (i) the Discretionary
Option Grant Program under which employees and consultants are granted options
to purchase shares of common stock at an exercise price per share not less than
85% of fair market value on the grant date, (ii) the Stock Issuance Program
under which such individuals may be issued shares of common stock directly,
through the purchase of such shares at a price per share not less than 85% fair
market value per share at the time of issuance or as a fully-paid bonus for
services rendered the Company; (iii) the Salary Investment Option Grant Program
under which the Company's officers may elect to have a portion of their base
salary applied each year to the acquisition of special below-market option
grants; and (iv) the Automatic Option Grant Program under which option grants
will automatically be made at periodic intervals to eligible non-employee board
members to purchase shares of Common Stock at an exercise price equal to 100% of
the fair market value of the option shares on the grant date.

     In January 1994, the Company authorized an exchange of stock options for a
like number of stock options at the then-fair value. The exchange was voluntary
and open to all employees holding options granted subsequent to certain dates.
All stock options received in exchange remain under the same vesting terms as
the previous options. In 1994, 235,081 options at an average option price of
$3.52 were exchanged for a like number of options at an option price of $1.60
per share.
 
     The Company recorded deferred compensation for the difference between the
grant price and the deemed fair value for financial statement presentation
purposes of the Company's common stock for certain options granted in July and
August 1995. Amortization of the deferred compensation was $212,000 and $89,000
in the years ended December 31, 1996 and 1995, respectively. The deferred
compensation amount is amortized over a four-year period, the vesting period of
the related stock options.
 
  Employee Stock Purchase Plan
 
     The Company's Employee Stock Purchase Plan (the "Purchase Plan") was
approved by the stockholders in October 1995. The Purchase Plan is designed to
allow eligible employees of the Company and participating subsidiaries to
purchase shares of common stock, at semi-annual intervals, through their
periodic payroll deductions under the Purchase Plan, and 100,000 shares of
common stock have been reserved for this purpose. The Company has issued 31,643
shares under this plan through December 31, 1996.
 
  Pro Forma Information -- Stock Based Compensation
 
     As of December 31, 1996, the Company has two stock based compensation
plans, which are described above. The Company has elected to follow APB 25 and
related interpretations in accounting for its employee stock options because, as
discussed below, the alternative fair value accounting provided for under SFAS
123 requires use of option valuation models that were not developed for use in
valuing employee stock options and employee stock purchase plans. Under APB 25,
when the exercise price of the Company's employee stock option equals the market
price of the underlying stock on the date of the grant, no compensation expense
is recognized.
 
     Pro forma information regarding net loss and net loss per share is required
by SFAS 123, and has been determined as if the Company had accounted for its
employee stock purchase plan and employee stock options granted subsequent to
December 31, 1994 under the fair value method of SFAS 123. The fair value for
these options was estimated at the date of grant using the minimum value method
for the options granted from January 1, 1995 through November 2, 1995 and the
Black-Scholes option pricing model for the options granted from November 3, 1995
to December 31, 1996. The following are the weighted-average assumptions for
1995 and 1996, respectively: risk free interest rate of 6.22% and 6.16%;
volatility factor of the expected market price of the Company's common stock of
 .70 for the

period from November 3, 1995 to December 31, 1996 and a weighted-average
expected life of the options of 5.74 and 4.87 years.
 
     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because the Company's employee stock option and stock purchase plans
have characteristics significantly different from those of traded options, and
because changes in the subjective input assumptions can materially affect the
fair value estimate, in management's opinion, the existing models do not
necessarily provide a reliable single measure of the fair value of the Company's
employee stock options and the employee stock purchase plan.
 
     For the purposes of pro forma disclosures, the estimated fair value of the
options is amortized to pro forma net loss over the options' vesting period. The
Company's historical and pro forma information follows (in thousands, except for
net loss per share information):

     Because SFAS 123 is applicable only to options granted subsequent to
December 31, 1994, its pro forma effect will not be fully realized until 1997.
 
  Shareholder Rights Plan
 
     On December 3, 1996, the Board of Directors adopted a Shareholder Rights
Plan (the Rights Plan). Under the Rights Plan one preferred share purchase right
(a "Right") is attached to each share of common stock of the Company. The Rights
Plan is designed to assist the Company's stockholders in realizing fair value
and equal treatment in the event of any attempted takeover of the Company and to
protect the Company and its stockholders against coercive takeover tactics. In
the event of certain changes in the Company's ownership, the Rights Plan allows
stockholders to purchase the Company's or the potential acquiror's common stock
with a market value of twice the Rights' then-current exercise price.
 
6.  401(K) SAVINGS AND RETIREMENT PLAN
 
     The Company has adopted a 401(k) Savings and Retirement Plan (the "Savings
Plan") to provide for voluntary salary deferral contributions on a pretax basis
in accordance with Section 401(k) of the Internal Revenue Code of 1986, as
amended. The Company has the option of matching a certain percentage of each
participant's contribution to the Savings Plan. As of December 31, 1996, the
Company has not made any matching contributions.
 
7.  INCOME TAXES
 
     Due to the Company's loss position, there was no provision or benefit for
income taxes for the years ended December 31, 1996, 1995 and 1994.

10.  SUBSEQUENT EVENTS
 
  Reorganization Agreement
 
     On January 26, 1997, Cardiometrics, EndoSonics Corporation, a Delaware
Corporation ("EndoSonics"), and River Acquisition Corporation, a Delaware
Corporation and a wholly owned subsidiary of EndoSonics ("Merger Sub"), entered
into an Agreement and Plan of Reorganization (the "Reorganization Agreement"),
pursuant to which Merger Sub will be merged with and into Cardiometrics (the
"Merger"), with Cardiometrics surviving the Merger and becoming a wholly owned
subsidiary of EndoSonics. The consummation of the Merger is subject, among other
things, to the approval of the Merger by the stockholders of Cardiometrics, at a
stockholders' meeting currently expected to be held in May 1997 and the
satisfaction of certain other closing conditions. Pursuant to the Reorganization
Agreement, shareholders of Cardiometrics will receive shares in EndoSonics,
shares in CardioVascular Dynamics, Inc. and cash, which, based on closing prices
on the last trading day prior to the execution of the Reorganization Agreement
(which values are subject to change), approximated $9.00 per share of
Cardiometrics common stock held by them. In the event Cardiometrics terminates
the Merger, under certain circumstances, Cardiometrics is obligated to pay up to
$3,500,000 in cash as a termination fee.
 
     On January 26, 1997, EndoSonics and Cardiometrics entered into a Stock
Option Agreement, pursuant to which, under limited circumstances, EndoSonics has
the right to acquire up to 1,379,717 shares of authorized, unissued shares of
Cardiometrics common stock at $9.00 per share. Under the terms of the Stock
Option Agreement, EndoSonics will remit to Cardiometrics any proceeds otherwise
payable to EndoSonics from any disposition of the Stock Option or the shares of
Cardiometrics Common Stock issued upon exercise of the Stock Option which are in
excess of the exercise price paid by EndoSonics to exercise the Stock Option.
 
  Litigation
 
     On January 28, 1997, an alleged class action complaint was filed in the New
Castle County Delaware Court of Chancery against the Company and other parties
seeking injunctive relief to prevent the consummation of the acquisition of the
Company by EndoSonics, or if the Merger is consummated, seeking rescission of
the Merger and payment of damages. The complaint, among other allegations,
alleges that the directors of the Company, two officers of the Company (one of
whom is a director), and a former director of the Company breached their
fiduciary and other duties to the Company's stockholders and that EndoSonics
knowingly aided and abetted such breaches. Cardiometrics believes the complaint
is without merit and intends to vigorously defend itself and the named
individual defendants against the allegations in the complaint.

(1) Each of the options listed in the table becomes exercisable as to 25% of the
    option shares upon completion of one year of service from the vesting date
    and the balance in a series of equal monthly installments over the next 36
    months of service thereafter. The option shares will vest upon an
    acquisition of Cardiometrics by merger, consolidation or asset sale. Each
    option has a maximum term of ten (10) years, subject to earlier termination
    in the event of the optionee's cessation of employment with Cardiometrics.
 
(2) The exercise price may be paid in cash, in shares of Cardiometrics' Common
    Stock valued at fair market value on the exercise date or through a cashless
    exercise procedure involving a same-day sale of the purchased shares.
    Cardiometrics may also finance the option exercise by loaning the optionee
    sufficient funds to pay the exercise price for the purchased shares,
    together with any federal and state income tax liability incurred by the
    optionee in connection with such exercise.
 
(3) The 5% and 10% assumed annual rates of compounded stock price appreciation
    are mandated by rules of the Securities and Exchange Commission. There can
    be no assurance provided to any executive officer or any other holder of
    Cardiometrics' securities that the actual stock price appreciation over the
    10-year option term will be at the assumed 5% and 10% levels or at any other
    defined level. Unless the market price of the Common Stock appreciates over
    the option term, no value will be realized from the option grants made to
    the executive officers.

option holdings for the fiscal year ended December 31, 1996 with respect to each

EMPLOYMENT AGREEMENTS AND CHANGE IN CONTROL ARRANGEMENTS
 
     The Company and Menaham Nassi, the Company's President and Chief Executive
Officer, have entered into an Employment Agreement dated December 13, 1990,
which was subsequently amended and restated on numerous occasions (the "Nassi
Employment Agreement"). Under the Nassi Employment Agreement, certain options
granted to Mr. Nassi will vest in full if Mr. Nassi is terminated without cause
(as defined in the Nassi Employment Agreement) or if the Company is acquired
before such options are fully vested. As of December 31, 1996, Mr. Nassi held
unvested options for a total of 33,985 shares, all of which will accelerate if
Mr. Nassi is terminated without cause (as defined in the
 
                                       49
<PAGE>   50
 
Nassi Employment Agreement) or if the Company is acquired and, accordingly, will
become fully vested upon consummation of the Merger.
 
     All of the Company's outstanding stock options and shares purchased under
options will vest in full upon a Corporate Transaction (as such term is defined
in the Company's 1995 Stock Incentive Plan) pursuant to resolutions adopted by
the Compensation Committee of the Company's Board of Directors on January 3,
1997. The acquisition of the Company by EndoSonics pursuant to the
Reorganization Agreement will constitute a Corporate Transaction and,
accordingly, all of the Company's outstanding stock options and shares purchased
under options will vest in full upon the closing of the Merger.
 
     SEVERANCE PLAN. On January 3, 1997, Cardiometrics adopted the Change in
Control Severance Plan ("Severance Plan"), which provides certain severance
benefits for eligible employees of Cardiometrics, including the Named Officers,
upon an Involuntary Termination (as defined in the Severance Plan) from
employment without cause within the 12 month period following a Change in
Control (as defined in the Severance Plan). The acquisition of the Company by
EndoSonics pursuant to the Reorganization Agreement will constitute a Change in
Control under the Severance Plan. The Severance Plan provides for the payment of
a cash severance benefit as a percentage of the eligible employee's annual base
pay at the time of termination and ranges from a low of 16 2/3% of annual base
pay to a high of 100% of annual base pay. If the employment of the Named
Officers were terminated in the 12-month period following the consummation of
the Merger, each would be entitled to a benefit (estimated as follows based on
the individual's current annual base pay): Dr. Nassi: $175,000, Mr. Sorna:
$65,000, Mr. Newell: $72,500, Mr. Frisbie: $66,000, and Mr. Rhatigan: $57,500.
The benefit payable under the Severance Plan is subject to reduction to avoid
imposition of excise taxes applicable to certain parachute payments under the
Federal tax laws.
 
ITEM 12.  SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT
 
     The following table sets forth certain information regarding the beneficial

ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
     In December 1996, the Company received a purchase order for approximately
$1 million from Goodman Co. Ltd. ("Goodman") for purchase of the Company's
WaveWire/WaveMap intracoronary blood pressure measurement system for delivery in
the second half of 1997 (the "Goodman Purchase Order"). Goodman owns more than
five percent of the Company's outstanding Common Stock. The Company believes
that the Goodman Purchase Order was made on terms no less favorable to the
Company than could have been obtained from unaffiliated third parties.
 
     In August 1996, the Company entered into an amendment to the employment
agreement with its President and Chief Executive Officer, Menahem Nassi ("Nassi
Employment Amendment"). The
 
                                       52
<PAGE>   53
 
Nassi Employment Amendment provides that commencing on February 1, 1996, Dr.
Nassi's gross salary shall be $13,958.33 per month. In addition, the Nassi
Employment Amendment also provides that Dr. Nassi is an at will employee,
however in the event that he is terminated without cause (as defined in the
Nassi Employment Agreement), Dr. Nassi shall be entitled to receive (i) salary
continuation for up to twelve (12) months (subject to discontinuation after six
(6) months should Dr. Nassi find another full-time job) and (ii) benefit
continuation for up to twelve (12) months (subject to discontinuation should Dr.
Nassi find another full-time job).

                              CARDIOMETRICS, INC.

                           1995 STOCK INCENTIVE PLAN

                                  ARTICLE ONE

                               GENERAL PROVISIONS



         I.      PURPOSE OF THE PLAN

                 This 1995 Stock Incentive Plan is intended to promote the
interests of Cardiometrics, Inc., a Delaware corporation, by providing eligible
persons with the opportunity to acquire a proprietary interest, or otherwise
increase their proprietary interest, in the Corporation as an incentive for
them to remain in the service of the Corporation.

                 Capitalized terms shall have the meanings assigned to such
terms in the attached Appendix.

         II.     STRUCTURE OF THE PLAN

                 A.       The Plan shall be divided into four separate equity
programs:

                          1.      the Discretionary Option Grant Program under
which eligible persons may, at the discretion of the Plan Administrator, be
granted options to purchase shares of Common Stock,

                          2.      the Salary Investment Option Grant Program
under which the Corporation's officers and other highly- compensated employees
may elect to have a portion of their base salary reduced each year in return
for options to purchase shares of Common Stock,

                          3.      the Stock Issuance Program under which
eligible persons may, at the discretion of the Plan Administrator, be issued
shares of Common Stock directly, either through the immediate purchase of such
shares or as a bonus for services rendered to the Corporation (or any Parent or
Subsidiary), and

                          4.      the Automatic Option Grant Program under
which Eligible Directors shall automatically receive option grants at periodic
intervals to purchase shares of Common Stock.

                 B.       The provisions of Articles One and Six shall apply to
all equity programs under the Plan and shall accordingly govern the interests
of all persons under the Plan.

         III.    ADMINISTRATION OF THE PLAN

                 A.       The Primary Committee shall have sole and exclusive
authority to administer the Discretionary Option Grant and Stock Issuance
Programs with respect to
<PAGE>   2

Section 16 Insiders.  No non-employee Board member shall be eligible to serve
on the Primary Committee if such individual has, during the twelve (12)-month
period immediately preceding the date of his or her appointment to the
Committee or (if shorter) the period commencing with the Section 12(g)
Registration Date and ending with the date of his or her appointment to the
Primary Committee, received an option grant or direct stock issuance under the
Plan or any other stock option, stock appreciation, stock bonus or other stock
plan of the Corporation (or any Parent or Subsidiary), other than pursuant to
the Automatic Option Grant Program.

                 B.       Administration of the Discretionary Option Grant and
Stock Issuance Programs with respect to all other persons eligible to
participate in those programs may, at the Board's discretion, be vested in the
Primary Committee or a Secondary Committee, or the Board may retain the power
to administer those programs with respect to all such persons.  The members of
the Secondary Committee may be Board members who are Employees eligible to
receive discretionary option grants or direct stock issuances under the Plan or
any other stock option, stock appreciation, stock bonus or other stock plan of
the Corporation (or any Parent or Subsidiary).

                 C.       Members of the Primary Committee or any Secondary
Committee shall serve for such period of time as the Board may determine and
shall be subject to removal by the Board at any time.  The Board may also at
any time terminate the functions of any Secondary Committee and reassume all
powers and authority previously delegated to such committee.

                 D.       Each Plan Administrator shall, within the scope of
its administrative functions under the Plan, have full power and authority to
establish such rules and regulations as it may deem appropriate for proper
administration of the Discretionary Option Grant and Stock Issuance Programs
and to make such determinations under, and issue such interpretations of, the
provisions of such programs and any outstanding options or stock issuances
thereunder as it may deem necessary or advisable.  Decisions of each Plan
Administrator within the scope of its administrative functions under the Plan
shall be final and binding on all parties who have an interest in the
Discretionary Option Grant or Stock Issuance Program under its jurisdiction or
any stock option or stock issuance outstanding thereunder.

                 E.       Service on the Primary Committee or the Secondary
Committee shall constitute service as a Board member, and members of each such
committee shall accordingly be entitled to full indemnification and
reimbursement as Board members for their service on such committee.  No member
of the Primary Committee or the Secondary Committee shall be liable for any act
or omission made in good faith with respect to the Plan or any option grants or
stock issuances under the Plan.

                 F.       Administration of the Automatic Option Grant Program
shall be self-executing in accordance with the terms of that program, and no
Plan Administrator shall exercise any discretionary functions with respect to
option grants made thereunder.

         IV.     ELIGIBILITY

                 A.       The persons eligible to participate in the
Discretionary Option Grant and Stock Issuance Programs are as follows:



                          1.      Employees,

                          2.      non-employee members of the Board (other than
those serving as members of the Primary Committee) or the board of directors of
any Parent or Subsidiary, and

                          3.      consultants or other independent advisors who
provide services to the Corporation (or any Parent or Subsidiary).

                 B.       Only the Corporation's officers and other
highly-compensated Employees shall be eligible to participate in the Salary
Investment Option Grant Program.

                 C.       The Plan Administrator shall, within the scope of its
administrative jurisdiction under the Plan, have full authority (subject to the
provisions of the Plan) to determine, (i) with respect to the option grants
under the Discretionary Option Grant Program, which eligible persons are to
receive option grants, the time or times when such option grants are to be
made, the number of shares to be covered by each such grant, the status of the
granted option as either an Incentive Option or a Non-Statutory Option, the
time or times at which each option is to become exercisable, the vesting
schedule (if any) applicable to the option shares and the maximum term for
which the option is to remain outstanding and (ii) with respect to stock
issuances under the Stock Issuance Program, which eligible persons are to
receive stock issuances, the time or times when such issuances are to be made,
the number of shares to be issued to each Participant, the vesting schedule (if
any) applicable to the issued shares and the consideration to be paid by the
Participant for such shares.   The Primary Committee shall have sole and
exclusive authority to select the individuals eligible to participate in the
Salary Investment Option Grant Program, but all options granted under such
program shall be made solely in accordance with the express terms and
conditions of Article Three of the Plan.

                 D.       The Plan Administrator shall have the absolute
discretion either to grant options in accordance with the Discretionary Option
Grant Program or to effect stock issuances in accordance with the Stock
Issuance Program.

                 E.       The individuals eligible to receive option grants
under the Automatic Option Grant Program shall be limited to (i) those
individuals who first become non-employee Board members on or after the Plan
Effective Date, whether through appointment by the Board or election by the
Corporation's stockholders, and (ii) those individuals who are re-elected to
serve as non-employee Board members at one or more Annual Stockholders Meetings
held after the Plan Effective Date.  A non-employee Board member who has
previously been in the employ of the Corporation (or any Parent or Subsidiary)
shall not be eligible to receive an initial option grant under the


                                       3
<PAGE>   4

Automatic Option Grant Program at the time he or she first becomes a
non-employee Board member, but shall be eligible to receive periodic option
grants under the Automatic Option Grant Program upon his or her subsequent
re-election to the Board at one or more Annual Stockholders Meetings.

         V.      STOCK SUBJECT TO THE PLAN

                 A.       The stock issuable under the Plan shall be shares of
authorized but unissued or reacquired Common Stock, including shares
repurchased by the Corporation on the open market.  The maximum number of
shares of Common Stock which may be issued over the term of the Plan shall not
exceed 1,399,914 shares.  Such authorized share reserve is comprised of the
number of shares which remained available for issuance, as of the Plan
Effective Date, under the Predecessor Plans as last approved by the
Corporation's stockholders, including the shares subject to the outstanding
options incorporated into the Plan, plus an increase of 225,000 shares approved
by the Board on April 3, 1996 and approved by the Corporation's stockholders on
May 16, 1996.

                 B.       No one person participating in the Plan may receive
options, separately exercisable stock appreciation rights and direct stock
issuances for more than 200,000 shares of Common Stock per calendar year,
except that for the calendar year in which such person first commences Service,
the limit shall be increased to 300,000 shares.

                 C.       Shares of Common Stock subject to outstanding options
shall be available for subsequent issuance under the Plan to the extent (i) the
options (including any options incorporated from the Predecessor Plans) expire
or terminate for any reason prior to exercise in full or (ii) the options are
canceled in accordance with the cancellation-regrant provisions of Article Two.
All shares issued under the Plan (including shares issued upon exercise of
options incorporated from the Predecessor Plans), whether or not those shares
are subsequently repurchased by the Corporation pursuant to its repurchase
rights under the Plan, shall reduce on a share-for-share basis the number of
shares of Common Stock available for subsequent issuance under the Plan.  In
addition, should the exercise price of an option under the Plan (including any
option incorporated from the Predecessor Plans) be paid with shares of Common
Stock or should shares of Common Stock otherwise issuable under the Plan be
withheld by the Corporation in satisfaction of the withholding taxes incurred
in connection with the exercise of an option or the vesting of a stock issuance
under the Plan, then the number of shares of Common Stock available for
issuance under the Plan shall be reduced by the gross number of shares for
which the option is exercised or which vest under the stock issuance, and not
by the net number of shares of Common Stock issued to the holder of such option
or stock issuance.

                 D.       Should any change be made to the Common Stock by
reason of any stock split, stock dividend, recapitalization, combination of
shares, exchange of shares or other change affecting the outstanding Common
Stock as a class without the Corporation's receipt of consideration,
appropriate adjustments shall be made to (i) the maximum number and/or class of
securities issuable under the Plan, (ii) the maximum number and/or class of
securities for which any one person may be granted options, separately
exercisable stock appreciation rights and direct stock issuances per calendar
year, (iii) the number and/or class of securities for which automatic option
grants are to be subsequently made per Eligible Director under the Automatic



                                        4
<PAGE>   5

Option Grant Program and (iv) the number and/or class of securities and the
exercise price per share in effect under each outstanding option (including any
option incorporated from the Predecessor Plans) in order to prevent the
dilution or enlargement of  benefits thereunder.  The adjustments determined by
the Plan Administrator shall be final, binding and conclusive.

                                  ARTICLE TWO

                       DISCRETIONARY OPTION GRANT PROGRAM



         I.      OPTION TERMS

                 Each option shall be evidenced by one or more documents in the
form approved by the Plan Administrator; provided, however, that each such
document shall comply with the terms specified below.  Each document evidencing
an Incentive Option shall, in addition, be subject to the provisions of the
Plan applicable to such options.

                 A.       EXERCISE PRICE.

                          1.      The exercise price per share shall be fixed
by the Plan Administrator but shall not be less than eighty-five percent (85%)
of the Fair Market Value per share of  Common Stock on the option grant date.

                          2.      The exercise price shall become immediately
due upon exercise of the option and shall, subject to the provisions of Section
I of Article Six and the documents evidencing the option, be payable in one or
more of the forms specified below:

                                  a)       cash or check made payable to the
Corporation,

                                  b)       shares of Common Stock held for the
requisite period necessary to avoid a charge to the Corporation's earnings for
financial reporting purposes and valued at Fair Market Value on the Exercise
Date, or

                                  c)       to the extent the option is
exercised for vested shares,  through a special sale and remittance procedure
pursuant to which the Optionee shall concurrently provide irrevocable written
instructions to (a) a Corporation-designated brokerage firm to effect the
immediate sale of the purchased shares and remit to the Corporation, out of the
sale proceeds available on the settlement date, sufficient funds to cover the
aggregate exercise price payable for the purchased shares plus all applicable
Federal, state and local income and employment taxes required to be withheld by
the Corporation by reason of such exercise and (b) the Corporation to deliver
the certificates for the purchased shares directly to such brokerage firm in
order to complete the sale transaction.

                 Except to the extent such sale and remittance procedure is
utilized, payment of the exercise price for the purchased shares must be made
on the Exercise Date.

                 B.       EXERCISE AND TERM OF OPTIONS.  Each option shall be
exercisable at such time or times, during such period and for such number of
shares as shall be determined by the Plan Administrator and set forth in the
documents evidencing the option.  However, no option shall have a term in
excess of ten (10) years measured from the option grant date.


                                       6
<PAGE>   7

                 C.       EFFECT OF TERMINATION OF SERVICE.

                          1.      The following provisions shall govern the
exercise of any options held by the Optionee at the time of cessation of
Service or death:

                                  a)       Any option outstanding at the time
of the Optionee's cessation of Service for any reason shall remain exercisable
for such period of time thereafter as shall be determined by the Plan
Administrator and set forth in the documents evidencing the option, but no such
option shall be exercisable after the expiration of the option term.

                                  b)       Any option exercisable in whole or
in part by the Optionee at the time of death may be subsequently exercised by
the personal representative of the Optionee's estate or by the person or
persons to whom the option is transferred pursuant to the Optionee's will or in
accordance with the laws of descent and distribution.

                                  c)       During the applicable post-Service
exercise period, the option may not be exercised in the aggregate for more than
the number of vested shares for which the option is exercisable on the date of
the Optionee's cessation of Service.  Upon the expiration of the applicable
exercise period or (if earlier) upon the expiration of the option term, the
option shall terminate and cease to be outstanding for any vested shares for
which the option has not been exercised.  However, the option shall,
immediately upon the Optionee's cessation of Service, terminate and cease to be
outstanding to the extent the option is not otherwise at that time exercisable
for vested shares.

                                  d)       Should the Optionee's Service be
terminated for Misconduct, then all outstanding options held by the Optionee
shall terminate immediately and cease to be outstanding.

                          2.      The Plan Administrator shall have complete
discretion, exercisable either at the time an option is granted or at any time
while the option remains outstanding, to:

                                  a)       extend the period of time for which
the option is to remain exercisable following the Optionee's cessation of
Service from the period otherwise in effect for that option to such greater
period of time as the Plan Administrator shall deem appropriate, but in no
event beyond the expiration of the option term, and/or

                                  b)       permit the option to be exercised,
during the applicable post-Service exercise period, not only with respect to
the number of vested shares of Common Stock for which such option is
exercisable at the time of the Optionee's cessation of Service but also with
respect to one or more additional installments in which the Optionee would have
vested had the Optionee continued in Service.

                 d.       STOCKHOLDER RIGHTS.  The holder of an option shall
have no stockholder rights with respect to the shares subject to the option
until such person shall have exercised the option, paid the exercise price and
become a holder of record of the purchased shares.


                                       7
<PAGE>   8



                 E.       REPURCHASE RIGHTS.  The Plan Administrator shall have
the discretion to grant options which are exercisable for unvested shares of
Common Stock.  Should the Optionee cease Service while holding such unvested
shares, the Corporation shall have the right to repurchase, at the exercise
price paid per share, any or all of those unvested shares.  The terms upon
which such repurchase right shall be exercisable (including the period and
procedure for exercise and the appropriate vesting schedule for the purchased
shares) shall be established by the Plan Administrator and set forth in the
document evidencing such repurchase right.

                 F.       LIMITED TRANSFERABILITY OF OPTIONS.  During the
lifetime of the Optionee, the option shall be exercisable only by the Optionee
and shall not be assignable or transferable other than by will or by the laws
of descent and distribution following the Optionee's death.  However, a
Non-Statutory Option may be assigned in whole or in part during Optionee's
lifetime in accordance with the terms of a Qualified Domestic Relations Order.
The assigned portion may only be exercised by the person or persons who acquire
a proprietary interest in the option pursuant to such Qualified Domestic
Relations Order.  The terms applicable to the assigned portion shall be the
same as those in effect for the option immediately prior to such assignment and
shall be set forth in such documents issued to the assignee as the Plan
Administrator may deem appropriate.

         II.     INCENTIVE OPTIONS

                 The terms specified below shall be applicable to all Incentive
Options.  Except as modified by the provisions of this Section II, all the
provisions of Articles One, Two and Six shall be applicable to Incentive
Options. Options which are specifically designated as Non- Statutory Options
when issued under the Plan shall not be subject to the terms of this Section
II.

                 A.       ELIGIBILITY.  Incentive Options may only be granted
to Employees.

                 B.       EXERCISE PRICE.  The exercise price per share shall
not be less than one hundred percent (100%) of the Fair Market Value per share
of Common Stock on the option grant date.

                 C.       DOLLAR LIMITATION.  The aggregate Fair Market Value
(determined as of the respective date or dates of grant) of the shares of
Common Stock for which one or more options granted to any Employee under the
Plan (or any other option plan of the Corporation or any Parent or Subsidiary)
may for the first time become exercisable as Incentive Options during any one
calendar year shall not exceed the sum of One Hundred Thousand Dollars
($100,000).  To the extent the Employee holds two (2) or more such options
which become exercisable for the first time in the same calendar year, the
foregoing limitation on the exercisability of such options as Incentive Options
shall be applied on the basis of the order in which such options are granted.

                 D.       10% STOCKHOLDER.  If any Employee to whom an
Incentive Option is granted is a 10% Stockholder, then the exercise price per
share shall not be less than one hundred ten percent (110%) of the Fair Market
Value per share of Common Stock on the option grant date, and the option term
shall not exceed five (5) years measured from the option grant date.


                                       8
<PAGE>   9

         III.    CORPORATE TRANSACTION/CHANGE IN CONTROL

                 A.       In the event of any Corporate Transaction, each
outstanding option shall automatically accelerate so that each such option
shall, immediately prior to the effective date of the Corporate Transaction,
become fully exercisable for all the shares of Common Stock at the time subject
to such option and may be exercised for any or all of those shares as
fully-vested shares of Common Stock.  However, an outstanding option shall not
so accelerate if and to the extent:  (i) such option is, in connection with the
Corporate Transaction, either to be assumed by the successor corporation (or
parent thereof) or to be replaced with a comparable option to purchase shares
of the capital stock of the successor corporation (or parent thereof), (ii)
such option is to be replaced with a cash incentive program of the successor
corporation which preserves the spread existing on the unvested option shares
at the time of the Corporate Transaction and provides for subsequent payout in
accordance with the same vesting schedule applicable to such option or (iii)
the acceleration of such option is subject to other limitations imposed by the
Plan Administrator at the time of the option grant.  The determination of
option comparability under clause (i) above shall be made by the Plan
Administrator, and its determination shall be final, binding and conclusive.

                 B.       All outstanding repurchase rights shall also
terminate automatically, and the shares of Common Stock subject to those
terminated rights shall immediately vest in full, in the event of any Corporate
Transaction, except to the extent: (i) those repurchase rights are to be
assigned to the successor corporation (or parent thereof) in connection with
such Corporate Transaction or (ii) such accelerated vesting is precluded by
other limitations imposed by the Plan Administrator at the time the repurchase
right is issued.

                 C.       Immediately following the consummation of the
Corporate Transaction, all outstanding options shall terminate and cease to be
outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

                 D.       Each option which is assumed in connection with a
Corporate Transaction shall be appropriately adjusted, immediately after such
Corporate Transaction, to apply to the number and class of securities which
would have been issuable to the Optionee in consummation of such Corporate
Transaction had the option been exercised immediately prior to such Corporate
Transaction.  Appropriate adjustments shall also be made to (i) the number and
class of securities available for issuance under the Plan following the
consummation of such Corporate Transaction, (ii) the exercise price payable per
share under each outstanding option, provided the aggregate exercise price
payable for such securities shall remain the same, and (iii) the maximum number
of securities and/or class of securities for which any one person may be
granted stock options, separately exercisable stock appreciation rights and
direct stock issuances under the Plan per calendar year.

                 E.       Any options which are assumed or replaced in the
Corporate Transaction and do not otherwise accelerate at that time shall
automatically accelerate (and any of the Corporation's outstanding repurchase
rights which do not otherwise terminate at the time of the Corporate
Transaction shall automatically terminate and the shares of Common Stock
subject to


                     
                                       9
<PAGE>   10
those terminated rights shall immediately vest in full) in the event the
Optionee's Service should subsequently terminate by reason of an Involuntary
Termination within twelve (12) months following the effective date of such
Corporate Transaction.  Any options so accelerated shall remain exercisable for
fully-vested shares until the earlier of (i) the expiration of the option term
or (ii) the expiration of the one (1)-year period measured from the effective
date of the Involuntary Termination.

                 F.       The Plan Administrator shall have the discretion,
exercisable either at the time the option is granted or at any time while the
option remains outstanding, to (i) provide for the automatic acceleration of
one or more outstanding options (and the automatic termination of one or more
outstanding repurchase rights with the immediate vesting of the shares of
Common Stock subject to those rights) upon the occurrence of a Change in
Control or (ii) condition any such option acceleration (and the termination of
any outstanding repurchase rights) upon the subsequent Involuntary Termination
of the Optionee's Service within a specified period following the effective
date of such Change in Control.  Any options accelerated in connection with a
Change in Control shall remain fully exercisable until the expiration or sooner
termination of the option term.

                 G.       The portion of any Incentive Option accelerated in
connection with a Corporate Transaction or Change in Control shall remain
exercisable as an Incentive Option only to the extent the applicable One
Hundred Thousand Dollar limitation is not exceeded.  To the extent such dollar
limitation is exceeded, the accelerated portion of such option shall be
exercisable as a Non-Statutory Option under the Federal tax laws.

                 H.       The grant of options under the Discretionary Option
Grant Program shall in no way affect the right of the Corporation to adjust,
reclassify, reorganize or otherwise change its capital or business structure or
to merge, consolidate, dissolve, liquidate or sell or transfer all or any part
of its business or assets.

         IV.     CANCELLATION AND REGRANT OF OPTIONS

                 The Plan Administrator shall have the authority to effect, at
any time and from time to time, with the consent of the affected option
holders, the cancellation of any or all outstanding options under the
Discretionary Option Grant Program (including outstanding options incorporated
from the Predecessor Plans) and to grant in substitution new options covering
the same or different number of shares of Common Stock but with an exercise
price per share based on the Fair Market Value per share of Common Stock on the
new grant date.

         V.      STOCK APPRECIATION RIGHTS

                 A.       The Plan Administrator shall have full power and
authority to grant to selected Optionees tandem stock appreciation rights
and/or limited stock appreciation rights.

                 B.       The following terms shall govern the grant and
exercise of tandem stock appreciation rights:


                                       10

<PAGE>   11



                          1.      One or more Optionees may be granted the
right, exercisable upon such terms as the Plan Administrator may establish, to
elect between the exercise of the underlying option for shares of Common Stock
and the surrender of that option in exchange for a distribution from the
Corporation in an amount equal to the excess of (a) the Fair Market Value (on
the option surrender date) of the number of shares in which the Optionee is at
the time vested under the surrendered option (or surrendered portion thereof)
over (b) the aggregate exercise price payable for such shares.

                          2.      No such option surrender shall be effective
unless it is approved by the Plan Administrator.  If the surrender is so
approved, then the distribution to which the Optionee shall be entitled may be
made in shares of Common Stock valued at Fair Market Value on the option
surrender date, in cash, or partly in shares and partly in cash, as the Plan
Administrator shall in its sole discretion deem appropriate.

                          3.      If the surrender of an option is rejected by
the Plan Administrator, then the Optionee shall retain whatever rights the
Optionee had under the surrendered option (or surrendered portion thereof) on
the option surrender date and may exercise such rights at any time prior to the
later of (a) five (5) business days after the receipt of the rejection notice
or (b) the last day on which the option is otherwise exercisable in accordance
with the terms of the documents evidencing such option, but in no event may
such rights be exercised more than ten (10) years after the  option grant date.

                 C.       The following terms shall govern the grant and
exercise of limited stock appreciation rights:

                          1.      One or more Section 16 Insiders may be
granted limited stock appreciation rights with respect to their outstanding
options.

                          2.      Upon the occurrence of a Hostile Take-Over,
each individual holding one or more options with such a limited stock
appreciation right in effect for at least six (6) months shall have the
unconditional right (exercisable for a thirty (30)-day period following such
Hostile Take-Over) to surrender each such option to the Corporation, to the
extent the option is at the time exercisable for vested shares of Common Stock.
In return for the surrendered option, the Optionee shall receive a cash
distribution from the Corporation in an amount equal to the excess of (A) the
Take-Over Price of the shares of Common Stock which are at the time vested
under each surrendered option (or surrendered portion thereof) over (B) the
aggregate exercise price payable for such shares.  Such cash distribution shall
be paid within five (5) days following the option surrender date.

                          3.      Neither the approval of the Plan
Administrator nor the consent of the Board shall be required in connection with
such option surrender and cash distribution.

                          4.      The balance of the option (if any) shall
continue in full force and effect in accordance with the documents evidencing
such option.

                     SALARY INVESTMENT OPTION GRANT PROGRAM



         I.      OPTION GRANTS

                 The Primary Committee shall have the sole and exclusive
authority to determine the calendar year or years (if any) for which the Salary
Investment Option Grant Program is to be in effect and to select the
Corporation's officers and other highly compensated Employees who are to
participate in the Salary Investment Option Grant Program for those calendar
year or years.  Each selected individual who elects to participate in the
Salary Investment Option Grant Program must, prior to the start of each
calendar year of participation, file with the Primary Committee (or its
designate) an irrevocable authorization directing the Corporation to reduce his
or her base salary for that calendar year by a designated multiple of one
percent (1%).  However, the minimum amount of such salary reduction must be not
less than five percent (5%) of the individual's current rate of annual base
salary and must not be more than twenty five percent (25%) of such base salary.
Each selected individual who files a proper salary reduction authorization
shall automatically be granted an option under this Salary Investment Option
Grant Program on the first trading day in January of the calendar year for
which that salary reduction is to be in effect.

         II.     OPTION TERMS

                 Each option shall be a Non-Statutory Option evidenced by one
or more documents in the form approved by the Primary Committee; provided,
however, that each such document shall comply with the terms specified below.

                 A.       EXERCISE PRICE.

                          1.      The exercise price per share shall be
thirty-three and one-third percent (33-1/3%) of the Fair Market Value per share
of Common Stock on the option grant date.

                          2.      The exercise price shall become immediately
due upon exercise of the option and shall be payable in one or more of the
alternative forms authorized under the Discretionary Option Grant Program.
Except to the extent the sale and remittance procedure specified thereunder is
utilized, payment of the exercise price for the purchased shares must be made
on the Exercise Date.

                 B.       NUMBER OF OPTION SHARES.  The number of shares of
Common Stock subject to the option shall be determined pursuant to the
following formula (rounded down to the nearest whole number):

                          X = A / (B x 66-2/3%), where



                                       12
<PAGE>   13

                          X is the number of option shares,

A is the dollar amount by which the Optionee's base salary is to be reduced for
the calendar year, and B is the Fair Market Value per share of Common Stock on
the option grant date.

                 C.       EXERCISE AND TERM OF OPTIONS.  The option shall
become exercisable in a series of twelve (12) successive equal monthly
installments upon the Optionee's completion of each calendar month of Service
in the calendar year for which the salary reduction is in effect.  Each option
shall have a maximum term of ten (10) years measured from the option grant
date.

                 D.       EFFECT OF TERMINATION OF SERVICE.  Should the
Optionee cease Service for any reason while holding one or more options under
this Article Three, then each such option shall remain exercisable, for any or
all of the shares for which the option is exercisable at the time of such
cessation of Service, until the expiration of the ten (10)-year option term.
Should the Optionee die while holding one or more options under this Article
Three, then each such option may be exercised, for any or all of the shares for
which the option is exercisable at the time of the Optionee's cessation of
Service (less any shares subsequently purchased by Optionee prior to death), by
the personal representative of the Optionee's estate or by the person or
persons to whom the option is transferred pursuant to the Optionee's will or in
accordance with the laws of descent and distribution.  Such right of exercise
shall lapse, and the option shall terminate, upon the expiration of the ten
(10)-year option term.  However, the option shall, immediately upon the
Optionee's cessation of Service for any reason, terminate and cease to remain
outstanding with respect to any and all shares of Common Stock for which the
option is not otherwise at that time exercisable.

         III.    CORPORATE TRANSACTION/CHANGE IN CONTROL

                 A.       Should any Corporate Transaction be effected while
the Optionee remains in Service, then each outstanding option held by such
Optionee under the Salary Investment Option Grant Program shall automatically
accelerate so that each such option shall, immediately prior to the effective
date of the Corporate Transaction, become fully exercisable with respect to the
total number of shares of Common Stock at the time subject to such option and
may be exercised for any or all of those shares as fully-vested shares of
Common Stock.  Each such outstanding option shall be assumed by the successor
corporation (or parent thereof) in the Corporate Transaction and shall remain
exercisable for the fully-vested shares until the expiration of the ten
(10)-year option term.

                 B.       Should any Change in Control occur while the Optionee
remains in Service, then each outstanding option held by such Optionee under
the Salary Investment Option Grant Program shall automatically accelerate so
that each such option shall, immediately prior to the effective date of the
Change in Control, become fully exercisable with respect to the total number of
shares of Common Stock at the time subject to such option and may be exercised
for


                                       13
<PAGE>   14

any or all of those shares as fully-vested shares of Common Stock.  The option
shall remain so exercisable until the expiration of the ten (10)-year option
term.

                 C.       The grant of options under the Salary Investment
Option Grant Program shall in no way affect the right of the Corporation to
adjust, reclassify, reorganize or otherwise change its capital or business
structure or to merge, consolidate, dissolve, liquidate or sell or transfer all
or any part of its business or assets.

         IV.     REMAINING TERMS

                 The remaining terms of each option granted under the Salary
Investment Option Grant Program shall be the same as the terms in effect for
option grants made under the Discretionary Option Grant Program.

                             STOCK ISSUANCE PROGRAM



         I.      STOCK ISSUANCE TERMS

                 Shares of Common Stock may be issued under the Stock Issuance
Program through direct and immediate issuances without any intervening option
grants.  Each such stock issuance shall be evidenced by a Stock Issuance
Agreement which complies with the terms specified below.

                 A.       PURCHASE PRICE.

                          1.      The purchase price per share shall be fixed
by the Plan Administrator, but shall not be less than eighty-five percent (85%)
of the Fair Market Value per share of Common Stock on the issuance date.

                          2.      Subject to the provisions of Section I of
Article Six, shares of Common Stock may be issued under the Stock Issuance
Program for any of the following items of consideration which the Plan
Administrator may deem appropriate in each individual instance:

                      a)       cash or check made payable to the Corporation, or

                      b)       past services rendered to the Corporation (or any
Parent or Subsidiary).

                 B.       VESTING PROVISIONS.

                          1.      Shares of Common Stock issued under the Stock
Issuance Program may, in the discretion of the Plan Administrator, be fully and
immediately vested upon issuance or may vest in one or more installments over
the Participant's period of Service or upon attainment of specified performance
objectives.  The elements of the vesting schedule applicable to any unvested
shares of Common Stock issued under the Stock Issuance Program, namely:

                       a)       the Service period to be completed by the 
Participant or the performance objectives to be attained,

                       b)       the number of installments in which
the shares are to vest,

                       c)       the interval or intervals (if any) which 
are to lapse between installments, and

                       d)       the effect which death, Permanent
Disability or other event designated by the Plan Administrator is to have upon
the vesting schedule,

                                        15

<PAGE>   16
shall be determined by the Plan Administrator and incorporated into the Stock
Issuance Agreement.

                          2.      Any new, substituted or additional securities
or other property (including money paid other than as a regular cash dividend)
which the Participant may have the right to receive with respect to his or her
unvested shares by reason of any stock dividend, stock split, recapitalization,
combination of shares, exchange of shares or other change affecting the
outstanding Common Stock as a class without the Corporation's receipt of
consideration shall be issued subject to (i) the same vesting requirements
applicable to the Participant's unvested shares and (ii) such escrow
arrangements as the Plan Administrator shall deem appropriate.

                          3.      The Participant shall have full stockholder
rights with respect to any shares of Common Stock issued to him or her under
the Stock Issuance Program, whether or not his or her interest in those shares
is vested.  Accordingly, the Participant shall have the right to vote such
shares and to receive any regular cash dividends paid on such shares.

                          4.      Should the Participant cease to remain in
Service while holding one or more unvested shares of Common Stock issued under
the Stock Issuance Program or should the performance objectives not be attained
with respect to one or more such unvested shares of Common Stock, then those
shares shall be immediately surrendered to the Corporation for cancellation,
and the Participant shall have no further stockholder rights with respect to
those shares.  To the extent the surrendered shares were previously issued to
the Participant for consideration paid in cash or cash equivalent (including
the Participant's purchase-money indebtedness), the Corporation shall repay to
the Participant the cash consideration paid for the surrendered shares and
shall cancel the unpaid principal balance of any outstanding purchase-money
note of the Participant attributable to the surrendered shares.

                          5.      The Plan Administrator may in its discretion
waive the surrender and cancellation of one or more unvested shares of Common
Stock (or other assets attributable thereto) which would otherwise occur upon
cessation of Service or the non-attainment of the performance objectives
applicable to those shares.  Such waiver shall result in the immediate vesting
of the Participant's interest in the shares of Common Stock as to which the
waiver applies.  Such waiver may be effected at any time, whether before or
after the Participant's cessation of Service or the attainment or
non-attainment of the applicable performance objectives.

         II.     CORPORATE TRANSACTION/CHANGE IN CONTROL

                 All of the Corporation's outstanding repurchase/cancellation
rights under the Stock Issuance Program shall terminate automatically, and all
the shares of Common Stock subject to those terminated rights shall immediately
vest in full, in the event of any Corporate Transaction, except to the extent
(i) those repurchase/cancellation rights are assigned to the successor
corporation (or parent thereof) in connection with such Corporate Transaction
or (ii) such accelerated vesting is precluded by other limitations imposed in
the Stock Issuance Agreement.

                                       16

<PAGE>   17

                 To the extent any repurchase/cancellation rights applicable to
the Participant's outstanding shares under the Stock Issuance Program are
assigned in the Corporate Transaction, those rights shall automatically
terminate, and the shares subject to those terminated rights shall immediately
vest in full, in the event the Participant's Service should subsequently
terminate by reason of an Involuntary Termination within twelve (12) months
following the effective date of such Corporate Transaction.

                 The Plan Administrator shall have the discretion, exercisable
either at the time the unvested shares are issued or at any time while the
Corporation's repurchase/cancellation rights remain outstanding, to (i) provide
for the automatic termination of one or more outstanding
repurchase/cancellation rights and the immediate vesting of the shares subject
to those rights upon the occurrence of a Change in Control or (ii) condition
any such accelerated vesting upon the subsequent Involuntary Termination of the
Participant's Service within a specified period following the effective date of
such Change in Control.

         III.    SHARE ESCROW/LEGENDS

                 Unvested shares may, in the Plan Administrator's discretion,
be held in escrow by the Corporation until the Participant's interest in such
shares vests or may be issued directly to the Participant with restrictive
legends on the certificates evidencing those unvested shares.

                         AUTOMATIC OPTION GRANT PROGRAM

         I.      OPTION TERMS

                 A.       GRANT DATES.  Option grants shall be made on the dates
specified below:

                          1.      Each Eligible Director who is first elected
or appointed as a non-employee Board member on or after the Plan Effective Date
shall automatically be granted, on the date of such initial election or
appointment, a Non-Statutory Option to purchase 5,000 shares of Common Stock,
provided such individual has not previously been in the employ of the
Corporation (or any Parent or Subsidiary).

                          2.      On the date of each Annual Stockholders
Meeting held after the Plan Effective Date, each individual who is to continue
to serve as a non-employee Board member shall automatically be granted a
Non-Statutory Option to purchase an additional 2,500 shares of Common Stock,
provided such individual has served as a non-employee Board member for a period
of at least six (6) months.  There shall be no limit on the number of such
2,500-share option grants any one Eligible Director may receive over his or her
period of Board service.

                 B.       EXERCISE PRICE.

                          1.      The exercise price per share shall be equal
to one hundred percent (100%) of the Fair Market Value per share of Common
Stock on the option grant date.

                          2.      The exercise price shall be payable in one or
more of the alternative forms authorized under the Discretionary Option Grant
Program.  Except to the extent the sale and remittance procedure specified
thereunder is utilized, payment of the exercise price for the purchased shares
must be made on the Exercise Date.

                 C.       OPTION TERM.  Each option shall have a term of ten
(10) years measured from the option grant date.

                 D.       EXERCISE AND VESTING OF OPTIONS.  Each option shall
be immediately exercisable for any or all of the option shares.  However, any
shares purchased under the option shall be subject to repurchase by the
Corporation, at the exercise price paid per share, upon the Optionee's
cessation of Board service prior to vesting in those shares.  Each initial
5,000-share grant shall vest, and the Corporation's repurchase right shall
lapse, in a series of twenty-four (24) successive equal monthly installments
over the Optionee's period of continued service as a Board member, with the
first such installment to vest upon the Optionee's completion of one (1) month
of Board service measured from the option grant date.  Each annual 2,500-share
grant shall vest, and the Corporation's repurchase right shall lapse in a
series of twelve (12) successive equal monthly installments over the Optionee's
period of continued service as a Board member, measured from the option grant
date.

                                       18

<PAGE>   19

                 E.       EFFECT OF TERMINATION OF BOARD SERVICE.  The
following provisions shall govern the exercise of any options held by the
Optionee at the time the Optionee ceases to serve as a Board member:

                                  1.       The Optionee (or, in the event of
the Optionee's death, the personal representative of the Optionee's estate or
the person or persons to whom the option is transferred pursuant to the
Optionee's will or in accordance with the laws of descent and distribution)
shall have a twelve (12)-month period following the date of the Optionee's
cessation of Board service in which to exercise each such option.

                                  2.       During the twelve (12)-month
exercise period, the option may not be exercised in the aggregate for more than
the number of vested shares of Common Stock for which the option is exercisable
at the time of the Optionee's cessation of Board service.

                                  3.       Should the Optionee cease to serve
as a Board member by reason of death or Permanent Disability, then all shares
at the time subject to the option shall immediately vest so that such option
may, during the twelve (12)-month exercise period following such cessation of
Board service, be exercised for all or any portion of those shares as
fully-vested shares of Common Stock.

                                  4.       In no event shall the option remain
exercisable after the expiration of the option term.  Upon the expiration of
the twelve (12)-month exercise period or (if earlier) upon the expiration of
the option term, the option shall terminate and cease to be outstanding for any
vested shares for which the option has not been exercised.  However, the option
shall, immediately upon the Optionee's cessation of Board service for any
reason other than death or Permanent Disability, terminate and cease to be
outstanding to the extent the option is not otherwise at that time exercisable
for vested shares.

         II.     CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE-OVER

                 A.       In the event of any Corporate Transaction, the shares
of Common Stock at the time subject to each outstanding option but not
otherwise vested shall automatically vest in full so that each such option
shall, immediately prior to the effective date of the Corporate Transaction,
become fully exercisable for all of the shares of Common Stock at the time
subject to such option and may be exercised for all or any portion of those
shares as fully-vested shares of Common Stock.  Immediately following the
consummation of the Corporate Transaction, each automatic option grant shall
terminate and cease to be outstanding, except to the extent assumed by the
successor corporation (or parent thereof).

                 B.       In connection with any Change in Control, the shares
of Common Stock at the time subject to each outstanding option but not
otherwise vested shall automatically vest in full so that each such option
shall, immediately prior to the effective date of the Change in Control, become
fully exercisable for all of the shares of Common Stock at the time subject to
such option and may be exercised for all or any portion of those shares as
fully-vested shares of Common Stock.  Each such option shall remain exercisable
for such fully-vested option shares


 
                                       19
<PAGE>   20

until the expiration or sooner termination of the option term or the cash-out
of the option in connection with a Hostile Take-Over.

                 C.       Upon the occurrence of a Hostile Take-Over, the
Optionee shall have a thirty (30)-day period in which to surrender to the
Corporation each automatic option held by him or her for a period of at least
six (6) months.  The Optionee shall in return be entitled to a cash
distribution from the Corporation in an amount equal to the excess of (i) the
Take-Over Price of the shares of Common Stock at the time subject to the
surrendered option (whether or not the Optionee is otherwise at the time vested
in those shares) over (ii) the aggregate exercise price payable for such
shares.  Such cash distribution shall be paid within five (5) days following

Board or any Plan Administrator shall be required in connection with such
option surrender and cash distribution.

would have been issuable to the Optionee in consummation of such Corporate
Transaction had the option been exercised immediately prior to such Corporate
Transaction.  Appropriate adjustments shall also be made to the exercise price
payable per share under each outstanding option, provided the aggregate
exercise price payable for such securities shall remain the same.

                 F.       The grant of options under the Automatic Option Grant
Program shall in no way affect the right of the Corporation to adjust,
reclassify, reorganize or otherwise change its capital or business structure or
to merge, consolidate, dissolve, liquidate or sell or transfer all or any part
of its business or assets.

         III.    AMENDMENT OF THE AUTOMATIC OPTION GRANT PROGRAM

                 The provisions of this Automatic Option Grant Program,
together with the option grants outstanding thereunder, may not be amended at
intervals more frequently than once every six (6) months, other than to the
extent necessary to comply with applicable Federal income tax laws and
regulations.

         IV.     REMAINING TERMS

                 The remaining terms of each option granted under the Automatic
Option Grant Program shall be the same as the terms in effect for option grants
made under the Discretionary Option Grant Program.

         I.      FINANCING

                 A.       The Plan Administrator may permit any Optionee or
Participant to pay the option exercise price under the Discretionary Option
Grant or Salary Investment Option Grant Program or the purchase price of shares
issued under the Stock Issuance Program by delivering a promissory note payable
in one or more installments.   The terms of any such promissory note (including
the interest rate and the terms of repayment) shall be established by the Plan
Administrator in its sole discretion.  Promissory notes may be authorized with
or without security or collateral.  In all events, the maximum credit available
to the Optionee or Participant may not exceed the sum of (i) the aggregate
option exercise price or purchase price payable for the purchased shares plus
(ii) any Federal, state and local income and employment tax liability incurred
by the Optionee or the Participant in connection with the option exercise or
share purchase.

                 B.       The Plan Administrator may, in its discretion,
determine that one or more such promissory notes shall be subject to
forgiveness by the Corporation in whole or in part upon such terms as the Plan
Administrator may deem appropriate.

         II.     TAX WITHHOLDING

                 A.       The Corporation's obligation to deliver shares of
Common Stock upon the exercise of stock options or stock appreciation rights or
upon the issuance or vesting of such shares under the Plan shall be subject to
the satisfaction of all applicable Federal, state and local income and
employment tax withholding requirements.

                 B.       The Plan Administrator may, in its discretion,
provide any or all holders of Non-Statutory Options or unvested shares of
Common Stock under the Plan (other than the options granted or the shares
issued under the Automatic Option Grant Program) with the right to use shares
of Common Stock in satisfaction of all or part of the Taxes incurred by such
holders in connection with the exercise of their options or the vesting of
their shares.  Such right may be provided to any such holder in either or both
of the following formats:

                          1.      STOCK WITHHOLDING:  The election to have the
Corporation withhold, from the shares of Common Stock otherwise issuable upon
the exercise of such Non-Statutory Option or the vesting of such shares, a
portion of those shares with an aggregate Fair Market Value equal to the
percentage of the Taxes (not to exceed one hundred percent (100%)) designated
by the holder.

                          2.      STOCK DELIVERY:  The election to deliver to
the Corporation, at the time the Non-Statutory Option is exercised or the
shares vest, one or more shares of Common Stock previously acquired by such

share vesting triggering the Taxes) with an aggregate Fair Market Value equal
to the percentage of the Taxes (not to exceed one hundred percent (100%))
designated by the holder.

         III.    EFFECTIVE DATE AND TERM OF THE PLAN

                 A.       The Plan shall become effective on the Plan Effective
Date, and the initial options under the Automatic Option Grant Program shall be
made to the Eligible Directors at that time.

                 B.       The Plan shall serve as the successor to the
Predecessor Plans, and no further option grants shall be made under the
Predecessor Plans after the Plan Effective Date.  All options outstanding under
the Predecessor Plans as of such date were incorporated into the Plan at that
time and shall be treated as outstanding options under the Plan.  However, each
outstanding option so incorporated shall continue to be governed solely by the
terms of the documents evidencing such option, and no provision of the Plan
shall be deemed to affect or otherwise modify the rights or obligations of the
holders of such incorporated options with respect to their acquisition of
shares of  Common Stock.

                 C.       One or more provisions of the Plan, including
(without limitation) the option/vesting acceleration provisions of Article Two
relating to Corporate Transactions and Changes in Control, may, in the Plan
Administrator's discretion, be extended to one or more options incorporated
from the Predecessor Plans which do not otherwise contain such provisions.

                 D.       On April 3, 1996, the Board approved an increase in
the number of shares issuable under the Plan by 225,000 shares to 1,399,914
shares, and the Corporation's stockholders approved such share increase at the
1996 Annual Stockholders Meeting.  No options may be exercised and no shares
may be issued on the basis of the 225,000 share increase prior to stockholder
approval of such increase.  Except as so limited, the Plan Administrator may
grant options at any time before expiration of the Plan.  The provisions in the
1996 restatement of the Plan shall apply only to options and stock awards
granted under the Plan from and after the effective date of such restatement.
All options and stock awards granted under the Plan immediately prior to the
effective date of such restatement shall continue to be governed by the terms
and conditions of the Plan (and the instrument evidencing each such option or
stock award) as in effect on the date each such option or stock award was
previously granted, and nothing in the 1996 restatement shall be deemed to
affect or otherwise modify the rights or obligations of the holders of such
options or stock awards with respect to the acquisition of shares of Common
Stock thereunder.

                 E.       The Plan shall terminate upon the earliest of (i)
September 30, 2005, (ii) the date on which all shares available for issuance
under the Plan shall have been issued pursuant to the exercise of the options
or the issuance of shares (whether vested or unvested) under the Plan or (iii)
the termination of all outstanding options in connection with a Corporate
Transaction.  Upon such Plan termination, all outstanding stock options and
unvested stock issuances shall continue to have force and effect in accordance
with the provisions of the documents evidencing such options or issuances.

         IV.     AMENDMENT OF THE PLAN

                 A.       The Board shall have complete and exclusive power and
authority to amend or modify the Plan in any or all respects.  However, (i) no
such amendment or modification shall adversely affect the rights and
obligations with respect to options, stock appreciation rights or unvested
stock issuances at the time outstanding under the Plan unless the Optionee or
the Participant consents to such amendment or modification, and (ii) any
amendment made to the Automatic Option Grant Program (or any options
outstanding thereunder) shall be in compliance with the limitations of that
program.  In addition, the Board shall not, without the approval of the
Corporation's stockholders, (i) materially increase the maximum number of
shares issuable under the Plan, the number of shares for which options may be
granted under the Automatic Option Grant Program or the maximum number of
shares for which any one person may be granted options, separately exercisable
stock appreciation rights and direct stock issuances in the aggregate per
calendar year, except for permissible adjustments in the event of certain
changes in the Corporation's capitalization, (ii) materially modify the
eligibility requirements for Plan participation or (iii) materially increase
the benefits accruing to Plan participants.

                 B.       Options to purchase shares of Common Stock may be
granted under the Discretionary Option Grant and Salary Investment Option Grant
Programs and shares of Common Stock may be issued under the Stock Issuance
Program that are in each instance in excess of the number of shares then
available for issuance under the Plan, provided any excess shares actually
issued under those programs are held in escrow until there is obtained
stockholder approval of an amendment sufficiently increasing the number of
shares of Common Stock available for issuance under the Plan.  If such
stockholder approval is not obtained within twelve (12) months after the date
the first such excess issuances are made, then (i) any unexercised options
granted on the basis of such excess shares shall terminate and cease to be
outstanding and (ii) the Corporation shall promptly refund to the Optionees and
the Participants the exercise or purchase price paid for any excess shares
issued under the Plan and held in escrow, together with interest (at the
applicable Short Term Federal Rate) for the period the shares were held in
escrow, and such shares shall thereupon be automatically canceled and cease to
be outstanding.

         V.      USE OF PROCEEDS

                 Any cash proceeds received by the Corporation from the sale of
shares of Common Stock under the Plan shall be used for general corporate
purposes.

         VI.     REGULATORY APPROVALS

                 A.       The implementation of the Plan, the granting of any
option or stock appreciation right under the Plan and the issuance of any
shares of Common Stock (i) upon the exercise of any option or stock
appreciation right or (ii) under the Stock Issuance Program shall be subject to
the Corporation's procurement of all approvals and permits required by
regulatory authorities having jurisdiction over the Plan, the options and stock
appreciation rights granted under it and the shares of Common Stock issued
pursuant to it.

<PAGE>   24

                 B.       No shares of Common Stock or other assets shall be
issued or delivered under the Plan unless and until there shall have been
compliance with all applicable requirements of Federal and state securities
laws, including the filing and effectiveness of the Form S-8 registration
statement for the shares of Common Stock issuable under the Plan, and all
applicable listing requirements of any stock exchange (or the Nasdaq National
Market, if applicable) on which Common Stock is then listed for trading.

         VII.    NO EMPLOYMENT/SERVICE RIGHTS

                 Nothing in the Plan shall confer upon the Optionee or the
Participant any right to continue in Service for any period of specific
duration or interfere with or otherwise restrict in any way the rights of the
Corporation (or any Parent or Subsidiary employing or retaining such person) or
of the Optionee or the Participant, which rights are hereby expressly reserved
by each, to terminate such person's Service at any time for any reason, with or
without cause.

                            SUMMARY PLAN DESCRIPTION



The Cardiometrics, Inc. Change in Control Severance Plan (the "Plan") is
primarily designed to provide eligible employees of Cardiometrics, Inc. (the
"Company") whose employment is terminated on or after January 3, 1997 with
separation pay in the event of an involuntary termination.

This Plan is designed to be an "employee welfare benefit plan," as defined in
Section 3(1) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA"). This Plan is governed by ERISA and, to the extent applicable, the
laws of the State of California. This document constitutes both the official
plan document and the required summary plan description under ERISA.

ELIGIBILITY

You will be an Eligible Employee for purposes of receiving severance benefits
under the Plan if:

       o      you are a regular, full-time employee of the Company;

       o      your active employment is Involuntarily Terminated within the
              twelve (12) month period following a Change in Control;

       o      you execute the General Release of All Claims (the "General
              Release"), a copy of which is attached as Exhibit A, within five
              (5) business days after your termination date or, if you are age
              forty (40) or over, you execute the General Release, a copy of
              which is attached as Exhibit B, within forty-five (45) business
              days after your termination; and

       o      you are not in one of the excluded categories listed below.

You are not eligible for severance benefits under this Plan if:

       o      you are a temporary employee, part-time employee working fewer
              than 32 hours per week, probationary employee or student employee;

       o      you voluntarily terminate employment;

       o      you are employed with a successor employer which directly or
              indirectly acquires (i) all or any portion of the assets or
              operations of the Company or any subsidiary, (ii) all or any
              portion of the outstanding capital stock of the Company, or (iii)
              fifty percent (50%) or more of the capital stock of any subsidiary
              of the Company. However, you would be eligible for severance
              benefits pursuant to the terms of the Plan upon a subsequent
              termination within 12 months following a Change in Control; or

                                        1


<PAGE>   3
      o       you are dismissed for Cause, whether or not you already received
              notice of a termination which would otherwise qualify you for
              severance benefits.

II.      HOW THE PLAN WORKS

If you are eligible for severance benefits under the Plan, the amount of your
severance pay will be determined in accordance with the guidelines set forth
below, subject to the Golden Parachute Tax limitation set forth below. You will
receive your severance pay in a lump-sum payment which will be made as soon as
administratively practicable after the occurrence of the following events:

              o      your Involuntary Termination within twelve months after a
                     Change in Control;

              o      the Company's receipt of your executed General Release; and

              o      the expiration of any rescission period applicable to your
                     executed General Release.

                              Severance Guidelines

If your employment is Involuntarily Terminated within twelve (12) months after a
Change in Control, you will be paid:

       o      100% of the Eligible Employee's Annual Base Pay, if the Eligible
              Employee was the President of the Company immediately before the
              Change in Control;

       o      50% of the Eligible Employee's Annual Base Pay, if the Eligible
              Employee was an officer (other than the President) of the Company
              immediately before the Change in Control;

       o      33-1/3% of the Eligible Employee's Annual Base Pay, if the
              Eligible Employee was a "director" or "manager" immediately before
              the Change in Control;

       o      25% of the Eligible Employee's Annual Base Pay, if the Eligible
              Employee was an exempt employee (other than an officer, director
              or manager) of the Company immediately before the Change in
              Control; or

       o      16 2/3% of the Eligible Employee's Annual Base Pay, if the
              Eligible Employee was a non-exempt employee of the Company
              immediately before the Change in Control.

Annual Base Pay generally means your base salary at the rate in effect during
the last regularly scheduled payroll period immediately preceding the occurrence
of the Change in Control and does not include, for example, bonuses, overtime
compensation, incentive pay, sales commissions or expense allowances.

                                       2

<PAGE>   4
Cause means (A) conduct on the part of the employee that (1) results or is
likely to result in material economic loss to the Company (or, if applicable, to
the successor entity) and (2) is continued by the employee following the
employee's receipt of a written request from the Company (or, if applicable,
from the successor entity) to cease engaging in such conduct, or (B) willful
misconduct or fraud on the part of the employee.

Change in Control shall be deemed to occur upon the consummation of any of the
following transactions:

       1.     a merger or consolidation in which the Company is not the
              surviving entity, except for a transaction the principal purpose
              of which is to change the state of the Company's incorporation; or

       2.     the sale, transfer or other disposition of all or substantially
              all of the assets of the Company; or

       3.     any reverse merger in which the Company is the surviving entity,
              but in which 50% or more of the Company's outstanding voting stock
              is transferred to holders different from those who held the stock
              immediately prior to such merger.

Involuntary Termination shall mean the termination of your employment with the
Company:

                     (A) involuntarily upon your discharge or dismissal other
              than for Cause, or

                     (B) voluntarily or involuntarily following (I) a reduction
              in your level of Annual Base Pay and any target bonus under
              non-discretionary and objective-standard incentive payment or
              bonus arrangement or (II) a change in your place of employment
              which is more than 50 miles from your place of employment prior to
              the change, provided and only if such change or reduction is
              effected without your written concurrence, or

                     (C) voluntarily or involuntarily in the case of an employee
              who was an officer, director or manager immediately before the
              applicable Change in Control, upon the employee's resignation
              following a change in the employee's position with the Company
              (or, if applicable, with the successor entity) that is effected
              without the employee's consent and materially reduces his or her
              level of responsibility or authority.

              Golden Parachute Tax Limitation

In the event that the cash severance payment you would receive under this Plan,
when added to any other payments or benefits received by you, would (i)
constitute "parachute payments" within the meaning of Section 280G of the
Internal Revenue Code ("Code") and (ii) be subject to the 20% excise tax imposed
by Section 4999 of the Code, then your cash severance payment hereunder shall be
limited to the lower of:

                                       3
<PAGE>   5

                  your cash severance amount under Section II, or

                  such amount which would, when added to your other parachute
                  payments, result in no portion of the compensation payable to
                  you being subject to excise tax under Section 4999 of the
                  Code.

No payments due you outside of this Plan shall be reduced by reason of this
paragraph. Any determination required to make this adjustment shall be made in
writing by the Company's independent public accountants or other outside
auditors selected by the Company immediately prior to the change of control
triggering the parachute payments, whose determination shall be binding upon you
and the Company. You and the Company are obligated to furnish to the accountants
such information and documents as the accountants may reasonably request. The
Company shall bear all costs of engaging the accountants in connection with
these calculations.

III.     OTHER IMPORTANT INFORMATION

Plan Administration. As the Plan Administrator, the Company has full
discretionary authority to administer and interpret the Plan, including
discretionary authority to determine eligibility for benefits under the Plan and
the amount of benefits (if any) payable per participant. Any determination by
the Plan Administrator will be final and conclusive upon all persons.

Benefits. When benefits are due, they will be paid from the general assets of
the Company. The Company is not required to establish a trust to fund the Plan.
The benefits provided under this Plan are not assignable and may be conditioned
upon your compliance with any confidentiality agreement you have entered into
with the Company or upon your compliance with any Company policy or program
communicated to you in writing.

Claims Procedure. If you believe you are incorrectly denied a benefit or are
entitled to a greater benefit than the benefit you receive under the Plan, you
may submit a signed, written application to the Plan Administrator within ninety
(90) days of your termination. You will be notified of the approval or denial of
this claim within ninety (90) days of the date that the Plan Administrator
receives the claim, unless special circumstances require an extension of time
for processing the claim. If your claim is denied, the notification will state
specific reasons for the denial and you will have sixty (60) days from receipt
of the written notification of the denial of your claim to file a signed,
written request for a review of the denial with the Plan Administrator. This
request should include the reasons you are requesting a review, facts supporting
your request and any other relevant comments. Pursuant to its discretionary
authority to administer and interpret the Plan and to determine eligibility for
benefits under the Plan, the Plan Administrator will generally make a final,
written determination of your eligibility for benefits within sixty (60) days of
receipt of your request for review.

Plan Terms. Except as otherwise set forth herein, this Plan supersedes any and
all prior separation, severance and salary continuation arrangements, programs
and plans which were previously offered by the Company for the purpose of paying
benefits upon a termination following a Change in Control, including pursuant to
employment agreement or offer letter. Nothing in this Plan shall affect an
employee's right to severance benefits under circumstances 




                                       4
<PAGE>   6
not involving a termination following a Change in Control. In no event, however,
shall any individual receive severance benefits under both this Plan and any
other separation, severance pay and salary continuation program, plan or other
arrangement with the Company.

Plan Amendment or Termination. The Company reserves the right to terminate or
amend the Plan at any time upon the vote of a two-thirds majority of the Board
of Directors; provided, however, that no amendment may be made after the
occurrence of a Change in Control. Any termination or amendment of the Plan may
be made effective immediately with respect to any benefits not yet paid, whether
or not prior notice of such amendment or termination has been given to affected
employees.

Taxes. The Company will withhold all applicable taxes and other payroll
deductions from any severance payment.

No Right To Employment. This Plan does not provide you with any right to
continue employment with the Company or affect the Company's right, which right
is hereby expressly reserved, to terminate the employment of any individual at
any time for any reason with or without cause.

STATEMENT OF ERISA RIGHTS

As a participant in the Plan, you are entitled to certain rights and protections
under the Employee Retirement Income Security Act of 1974, as amended ("ERISA").
ERISA provides that all Plan participants shall be entitled to:

       1.     Examine, without charge, at the Plan Administrator's office, all
              Plan documents, including all documents filed by the Plan with the
              U.S. Department of Labor.

       2.     Obtain copies of all Plan documents and other Plan information
              upon written request to the Plan Administrator. The Plan
              Administrator may make a reasonable charge for the copies.

       3.     File suit in a federal court, if you, as a participant, request
              materials and do not receive them within thirty (30) days of your
              request. In such a case, the court may require the Plan
              Administrator to provide the materials and to pay you a fine of up
              to $100 for each day's delay until the materials are received,
              unless the materials were not sent because of reasons beyond the
              control of the Plan Administrator.

In addition to creating rights for certain employees of the Company under the
Plan, ERISA imposes obligations upon the people who are responsible for the
operation of the Plan. The people who operate the Plan (called "fiduciaries")
have a duty to do so prudently and in the interest of the Company's employees
who are covered by the Plan.

No one, including your employer or any other person, may fire you or otherwise
discriminate against you in any way to prevent you from obtaining a benefit to
which you are entitled under the Plan or from exercising your rights under
ERISA.


                                       5
<PAGE>   7

If your claim for a severance benefit is denied or ignored, in whole or in part,
you have a right to file suit in a federal or a state court. If Plan fiduciaries
are misusing the Plan's assets (if any) or if you are discriminated against for
asserting your rights, you may seek assistance from the U.S. Department of Labor
or file suit in a federal court. The court will decide who will pay court costs
and legal fees. If you are successful in your lawsuit, the court may, if it so
decides, order the party you have sued to pay your legal costs, including
attorney fees. However, if you lose, the court may order you to pay these costs
and fees, for example, if it finds that your claim or suit is frivolous.

If you have any questions about the Plan, this statement or your rights under
ERISA, you should contact the Plan Administrator or the nearest Area Office of
the U.S. Labor-Management Services Administration, Department of Labor.
