Dear Stockholder:
 
     I am pleased to forward the enclosed Proxy Statement/Prospectus for the
Special Meeting (the "Cardiometrics Meeting") of the Stockholders of
Cardiometrics, Inc. ("Cardiometrics") to be held July 23, 1997 at 10:00 a.m.
local time, at Cardiometrics' facilities located at 645 Clyde Avenue, Mountain
View, California. The purpose of the Cardiometrics Meeting is to consider and
vote upon the combination of Cardiometrics with Endosonics Corporation
("EndoSonics") through the merger (the "Merger") of River Acquisition
Corporation ("Merger Sub"), a wholly-owned subsidiary of EndoSonics, with and
into Cardiometrics.
 
     The Merger is subject to the terms and conditions of an Agreement and Plan
of Reorganization, dated as of January 26, 1997, as subsequently amended (the
"Reorganization Agreement"), by and among EndoSonics, Merger Sub and
Cardiometrics. In the Merger, Merger Sub will be merged with and into
Cardiometrics; Cardiometrics will be the surviving corporation and will become a
wholly-owned subsidiary of EndoSonics. Pursuant to the Merger, each outstanding
share of the 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 the following (the "Merger Consideration"): (i) .35 shares of
EndoSonics Common Stock (the "EndoSonics Exchange Ratio"); (ii) $3.00 in cash
(the "Cash Consideration"); and (iii) at least .1364 but no more than .19 shares
of CardioVascular Dynamics, Inc. ("CVD") Common Stock (adjusted as set forth in
the following sentence, the "CVD Exchange Ratio"). If, based on the average
closing prices of EndoSonics Common Stock and CVD Common Stock for the ten
trading days immediately preceding (and including) the third trading day prior
to the Cardiometrics Meeting and using a CVD Exchange Ratio of .1364, the Merger
Consideration would be less than $8.00, the CVD Exchange Ratio will be increased
from .1364 such that the Merger Consideration shall equal $8.00, but in no event
shall the CVD Exchange Ratio exceed .19. As a result, because the Reorganization
Agreement does not contain a minimum value for the Merger Consideration or allow
Cardiometrics to terminate the Merger if the Merger Consideration falls below a
specified value, the value of the Merger Consideration may be lower than $8.00
per share at the time of closing.
 
     For current information on the value of the Merger Consideration and the
CVD Exchange Ratio, you are encouraged to call Cardiometrics at (800) 440-2356.
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 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. Each outstanding warrant to purchase shares of Cardiometrics Common
Stock, pursuant to its terms, will be assumed by EndoSonics upon the
consummation of the Merger and upon payment of the same aggregate exercise price
for such warrant prior to the Merger be exercisable for the Merger Consideration
multiplied by the number of shares of
<PAGE>   3
 
Cardiometrics Common Stock subject to such warrant immediately prior to the
Merger. Cardiometrics stockholders will receive cash in lieu of fractional
shares of EndoSonics Common Stock and CVD Common Stock. The shares of EndoSonics
Common Stock held by EndoSonics stockholders prior to the Merger will remain
unchanged by the Merger, except for dilution resulting from the Merger. Based on
the capitalization of Cardiometrics and EndoSonics as of May 30, 1997, it is
expected that, as a result of the Merger, EndoSonics will issue approximately
2,339,000 shares by virtue of the Merger, which would represent approximately
14.7% of EndoSonics' outstanding Common Stock.
 
     The accompanying Notice of Special Meeting and Proxy Statement/Prospectus
provides a detailed description of the Reorganization Agreement, certain
business and financial information of EndoSonics, CVD and Cardiometrics and
other important information, which you are urged to read carefully. A copy of
the Reorganization Agreement is attached to the Proxy Statement/Prospectus as
Appendix A.
 
     THE CARDIOMETRICS BOARD OF DIRECTORS (THE "CARDIOMETRICS BOARD") HAS
CAREFULLY REVIEWED AND CONSIDERED THE TERMS AND CONDITIONS OF THE REORGANIZATION
AGREEMENT AND THE PROPOSED MERGER. THE CARDIOMETRICS BOARD BELIEVES THE TERMS
AND CONDITIONS OF THE REORGANIZATION AGREEMENT AND THE PROPOSED MERGER ARE FAIR
TO, AND IN THE BEST INTERESTS OF, THE CARDIOMETRICS STOCKHOLDERS. THE
CARDIOMETRICS BOARD HAS APPROVED THE TERMS AND CONDITIONS OF THE REORGANIZATION
AGREEMENT AND THE MERGER, AND RECOMMENDS THAT THE CARDIOMETRICS STOCKHOLDERS
VOTE "FOR" APPROVAL OF THE REORGANIZATION AGREEMENT AND THE CONSUMMATION OF THE
MERGER.
 
     The Cardiometrics Board received a written opinion dated as of January 26,
1997 (the "Dillon Read Opinion") from Dillon, Read & Co. Inc. ("Dillon Read"),
Cardiometrics' financial advisor, that, as of such date, and based upon and
subject to the factors and assumptions set forth in such written opinion the
consideration to have been received by the holders of Cardiometrics Common Stock
pursuant to the Merger before an amendment to the Reorganization Agreement,
which original merger consideration was modified in certain respects by said
amendment, was fair to such holders, from a financial point of view. A copy of
the Dillon Read Opinion is attached to the Proxy Statement/Prospectus as
Appendix C. Cardiometrics stockholders are urged to read the Dillon Read Opinion
in its entirety. Accordingly, the Dillon Read Opinion does not speak to the
Merger Consideration, which the Cardiometrics Board considered to be more
favorable to Cardiometrics stockholders than the original merger consideration.
 
     The Reorganization Agreement and the consummation of the Merger must be
approved by the holders of Cardiometrics Common Stock representing a majority of
the outstanding shares of Cardiometrics Common Stock entitled to vote. Your vote
on this matter is very important. We urge you to review carefully the enclosed
material and to return your proxy promptly.
 
     Whether or not you plan to attend the Cardiometrics Meeting, please mark,
sign, date and promptly return your proxy card in the enclosed postage-paid
envelope. If you attend the meeting, you may vote in person if you wish, even
though you have previously returned your proxy. You should not send in the stock
certificate(s) for your Cardiometrics Common Stock at this time.
 
     On behalf of the Cardiometrics Board, I thank you for your support and urge
you to vote FOR approval of the Reorganization Agreement and the consummation of
the Merger.
 
                                          Sincerely,

                   NOTICE OF SPECIAL MEETING OF STOCKHOLDERS
                            TO BE HELD JULY 23, 1997
 
To the Stockholders of Cardiometrics, Inc.:
 
     NOTICE IS HEREBY GIVEN that a Special Meeting (the "Cardiometrics Meeting")
of Stockholders of Cardiometrics, Inc., a Delaware corporation
("Cardiometrics"), will be held at 10:00 a.m., local time, on July 23, 1997 at
Cardiometrics' facilities located at 645 Clyde Avenue, Mountain View, California
for the following purposes:
 
          1. To consider and vote upon a proposal to approve (a) the Agreement
     and Plan of Reorganization, dated as of January 26, 1997, as subsequently
     amended (the "Reorganization Agreement"), by and among Endosonics
     Corporation, a Delaware corporation ("EndoSonics"), River Acquisition
     Corporation, a Delaware corporation and a newly formed, wholly-owned
     subsidiary of EndoSonics ("Merger Sub"), and Cardiometrics, and (b) the
     merger of Merger Sub with and into Cardiometrics (the "Merger") whereby,
     among other things, Cardiometrics will survive the Merger and become a
     wholly-owned subsidiary of EndoSonics, each outstanding share of
     Cardiometrics Common Stock, $.01 par value per share ("Cardiometrics Common
     Stock"), will be converted into the right to receive the following (the
     "Merger Consideration"): (i) .35 shares of EndoSonics Common Stock (the
     "EndoSonics Exchange Ratio"); (ii) $3.00 in cash (the "Cash
     Consideration"); and (iii) at least .1364 but no more than .19 shares of
     CardioVascular Dynamics, Inc. ("CVD") Common Stock (adjusted as set forth
     in the following sentence, the "CVD Exchange Ratio"). If, based on the
     average closing prices of EndoSonics Common Stock and CVD Common Stock for
     the ten trading days immediately preceding (and including) the third
     trading day prior to the Cardiometrics Meeting and using a CVD Exchange
     Ratio of .1364, the Merger Consideration would be less than $8.00, the CVD
     Exchange Ratio will be increased from .1364 such that the Merger
     Consideration shall equal $8.00, but in no event shall the CVD Exchange
     Ratio exceed .19. As a result, because the Reorganization Agreement does
     not contain a minimum value for the Merger Consideration or allow
     Cardiometrics to terminate the Merger if the Merger Consideration falls
     below a specified value, the value of the Merger Consideration may be lower
     than $8.00 per share at the time of closing.
 
          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 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. Each outstanding warrant to purchase shares of
     Cardiometrics Common Stock, pursuant to its terms, will be assumed by
     EndoSonics upon the consummation of the Merger and upon payment of the same
     aggregate exercise price for such warrant prior to the Merger be
     exercisable for the Merger Consideration multiplied by the number of shares
     of Cardiometrics
<PAGE>   5
 
     Common Stock subject to such warrant immediately prior to the Merger.
     Cardiometrics stockholders will receive cash in lieu of fractional shares
     of EndoSonics Common Stock and CVD Common Stock.
 
          2. To transact such other business as may properly come before the
     Cardiometrics Meeting or any adjournment or postponement thereof.
 
     The foregoing items of business are more fully described in the Proxy
Statement/Prospectus, a copy of which is attached hereto and made a part hereof
and which you are urged to read carefully.
 
     The Board of Directors has fixed the close of business on May 30, 1997 as
the record date for determining stockholders entitled to notice of and to vote
at the Cardiometrics Meeting and any adjournment or postponement thereof.
Approval of the Reorganization Agreement and the Merger will require the
affirmative vote of the holders of Cardiometrics Common Stock representing a
majority of the outstanding shares of Cardiometrics Common Stock entitled to
vote.
 
     A summary of certain provisions of Section 262 of the Delaware General
Corporation Law (the "DGCL") pertaining to the rights of dissenting stockholders
in connection with the Merger is included in the Proxy Statement/Prospectus in
the section entitled "The Merger and Related Transactions -- Appraisal Rights."
The complete text of Section 262 of the DGCL is set forth as Appendix B to the
Proxy Statement/Prospectus.
 
     TO ASSURE THAT YOUR SHARES ARE REPRESENTED AT THE CARDIOMETRICS MEETING,
YOU ARE URGED TO COMPLETE, DATE AND SIGN THE ENCLOSED PROXY AND MAIL IT PROMPTLY
IN THE POSTAGE-PAID ENVELOPE PROVIDED, WHETHER OR NOT YOU PLAN TO ATTEND THE
CARDIOMETRICS MEETING IN PERSON. YOU MAY REVOKE YOUR PROXY IN THE MANNER
DESCRIBED IN THE ACCOMPANYING PROXY STATEMENT/PROSPECTUS AT ANY TIME BEFORE IT
HAS BEEN VOTED AT THE CARDIOMETRICS MEETING. ANY STOCKHOLDER ATTENDING THE
CARDIOMETRICS MEETING MAY VOTE IN PERSON EVEN IF SUCH STOCKHOLDER HAS RETURNED A
PROXY.
 
                                          BY ORDER OF THE BOARD OF DIRECTORS

                      CARDIOMETRICS, INC. PROXY STATEMENT
                            ------------------------
 
                       ENDOSONICS CORPORATION PROSPECTUS
 
    This Proxy Statement/Prospectus is being furnished to the stockholders of
Cardiometrics, Inc., a Delaware corporation ("Cardiometrics"), in connection
with the solicitation of proxies by the Cardiometrics Board of Directors for use
at the Special Meeting of Cardiometrics stockholders (the "Cardiometrics
Meeting") to be held at 10:00 a.m., local time, on July 23, 1997, at
Cardiometrics' facilities located at 645 Clyde Avenue, Mountain View, California
and at any adjournments or postponements of the Cardiometrics Meeting.
 
    This Proxy Statement/Prospectus constitutes the Prospectus of Endosonics
Corporation, a Delaware corporation ("EndoSonics"), for use in connection with
the offer and issuance of shares of Common Stock of EndoSonics, par value $.001
per share ("EndoSonics Common Stock"), pursuant to the merger (the "Merger") of
River Acquisition Corporation, a Delaware corporation and a newly-formed,
wholly-owned subsidiary of EndoSonics ("Merger Sub"), with and into
Cardiometrics under the terms of the Agreement and Plan of Reorganization, dated
as of January 26, 1997, as subsequently amended, by and among EndoSonics, Merger
Sub and Cardiometrics (the "Reorganization Agreement"). A prospectus with
respect to the shares of CardioVascular Dynamics, Inc. Common Stock to be
transferred in the Merger is attached as Appendix G to the Proxy Statement. In
the Merger, Merger Sub will be merged with and into Cardiometrics; Cardiometrics
will be the surviving corporation and will become a wholly-owned subsidiary of
EndoSonics (such resulting wholly-owned subsidiary sometimes referred to herein
as the "Surviving Corporation").
 
    Pursuant to the Merger, each outstanding share of the 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 the
following (the "Merger Consideration"): (i) .35 shares of EndoSonics Common
Stock (the "EndoSonics Exchange Ratio"); (ii) $3.00 in cash (the "Cash
Consideration"); and (iii) at least .1364 but no more than .19 shares of
CardioVascular Dynamics, Inc. ("CVD") Common Stock (adjusted as set forth in the
following sentence, the "CVD Exchange Ratio"). If, based on the average closing
prices of EndoSonics Common Stock and CVD Common Stock for the ten trading days
immediately preceding (and including) the third trading day prior to the
Cardiometrics Meeting and using a CVD Ratio of .1364, the Merger Consideration
would be less than $8.00, the CVD Exchange Ratio will be increased from .1364
such that the Merger Consideration shall equal $8.00, but in no event shall the
CVD Exchange Ratio exceed .19. As an example of the consideration to be provided
to stockholders of Cardiometrics in connection with the Merger, based upon the
average of the closing prices of EndoSonics Common Stock and CVD Common Stock
for the ten trading days immediately preceding (and including) June 11, 1997 of
$11.36875 and $8.15, respectively, each share of Cardiometrics Common Stock
would be converted into the right to receive 0.35 shares of EndoSonics Common
Stock, .1364 shares of CVD Common Stock and $3.00 of cash, which, based on the
closing prices of EndoSonics Common Stock and CVD Common Stock on June 11, 1997
of $11.125 and $8.50, respectively, was equal to a per share consideration
valued at $8.05. Shares of Cardiometrics Common Stock held by EndoSonics will be
cancelled and extinguished without any conversion thereof. 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 at the EndoSonics Exchange Ratio, with the balance converted into the
right to receive a payment from EndoSonics, to be made in cash and shares of CVD
Common Stock. Within five days following the effectiveness of the Merger,
EndoSonics will file a Registration Statement on Form S-8 with the Securities
and Exchange Commission with respect to the shares of EndoSonics Common Stock
issuable upon exercise of the assumed Cardiometrics Options. Each outstanding
warrant to purchase shares of Cardiometrics Common Stock, pursuant to its terms,
will be assumed by EndoSonics upon the consummation of the Merger and become
exercisable for the Merger Consideration multiplied by the number of shares of
Cardiometrics Common Stock subject to such warrant immediately prior to the
Merger. Cardiometrics stockholders will receive cash in lieu of fractional
shares of EndoSonics Common Stock and CVD Common Stock. The shares of EndoSonics
Common Stock held by EndoSonics stockholders prior to the Merger will remain
unchanged by the Merger, except for dilution resulting from the Merger. Based on
6,982,541 shares of Cardiometrics Common Stock outstanding at June 11, 1997, and
giving effect to the cancellation of 300,000 shares of Cardiometrics Common
Stock owned by EndoSonics, an aggregate of approximately 2,339,000 shares of
EndoSonics Common Stock will be issued by EndoSonics in the Merger, an aggregate
of approximately 911,000 shares of CVD Common Stock previously held be
EndoSonics and approximately $20,048,000 in cash will be transferred to
Cardiometrics stockholders in connection with the Merger; and, based on 816,658
shares of Cardiometrics Common Stock subject to outstanding Cardiometrics
Options at June 11, 1997, options to purchase an aggregate of approximately
286,000 additional shares of EndoSonics Common Stock will be assumed by
EndoSonics in the Merger, with a payment of an aggregate of approximately 71,000
shares of CVD Common Stock and approximately $1,568,000 in cash made to holders
of such Cardiometrics Options.
 
    On June 11, 1997, the closing sales prices on the Nasdaq National Market of
EndoSonics Common Stock, CVD Common Stock and Cardiometrics Common Stock were
$11.125, $8.50 and $7.00, respectively. The recent stock prices of each of
EndoSonics and CVD have been highly volatile. Such volatility could affect the
value of the Merger Consideration and the CVD Exchange Ratio. For current
information on the value of the Merger Consideration and the CVD Exchange Ratio,
stockholders are encouraged to call Cardiometrics at (800) 440-2356.

     The following is a brief summary of certain information contained elsewhere
in this Proxy Statement/Prospectus, the Appendices hereto and documents
incorporated by reference herein. The summary does not contain a complete
statement of material information relating to the Reorganization Agreement, the
Merger or the other matters discussed herein and is subject to, and qualified in

Statement/Prospectus and the Appendices in their entirety.
 
     This Proxy Statement/Prospectus contains forward-looking statements about
future results which are subject to risks and uncertainties. Cardiometrics' and
EndoSonics' actual results may differ significantly from the results discussed
in the forward-looking statements. Factors that might cause such a difference
include, but are not limited to, those discussed in "Risk Factors."
 
THE COMPANIES
 
  EndoSonics
 
     EndoSonics develops, manufactures and markets intravascular ultrasound
("IVUS") imaging systems and percutaneous transluminal coronary angioplasty
("balloon angioplasty") catheters to assist in the diagnosis and treatment of
cardiovascular and peripheral vascular disease. EndoSonics' IVUS imaging
products enhance the effectiveness of the diagnosis and treatment of coronary
artery and other vascular diseases by providing important diagnostic information
not available from conventional x-ray angiography. This information includes the
location, amount and composition of atherosclerotic plaque and enables
physicians to identify lesion characteristics, select an optimum course of
treatment, position therapeutic devices, treat disease sites with drugs or other
therapies and promptly assess the results of treatment.
 
     EndoSonics' products are based on two core proprietary technologies:
digital, all-electronic IVUS imaging and specialized balloon catheter material
technology. EndoSonics' IVUS imaging system and catheters use high-speed,
computer-based electronics and proprietary integrated circuit technologies to
produce ultrasound images. Unless otherwise indicated, "EndoSonics" refers to
Endosonics Corporation, a Delaware corporation, and its subsidiaries. EndoSonics
was incorporated in California in 1984 and reincorporated in Delaware in 1992.
EndoSonics' principal executive offices are located at 2870 Kilgore Road, Rancho
Cordova, California 95670. Its telephone number is (916) 638-8008.
 
  Cardiometrics
 
     Cardiometrics 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. 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 FDA and many corresponding European and Pacific Rim
regulatory agencies.
 
     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" refers to Cardiometrics, Inc., a Delaware corporation.
Cardiometrics was incorporated in California in 1985 and reincorporated in
Delaware in 1995. Cardiometrics' principal executive offices are located at 645
Clyde Avenue, Mountain View, California 94043. Its telephone number is (415)
961-6993.
<PAGE>   13
 
  CVD
 
     CVD designs, develops, manufactures and markets catheters used to treat
certain vascular diseases. The Company's catheters are used in conjunction with
angioplasty and other interventional procedures such as vascular stenting and
drug delivery. CVD's proprietary Focus and Multiple Microporous Membrane
technologies enable physicians to deliver therapeutic radial force, stents,
drugs or contrast media accurately and effectively to the treatment site, and
also allow the perfusion of blood during an interventional procedure. CVD
believes that the combination of these technologies on a multiple-purpose
catheter enables physicians to effectively perform challenging interventional
procedures, resulting in improved treatment outcomes and lower costs.
 
     The shares of CVD Common Stock to be transferred to the Cardiometrics
stockholders in connection with the Merger (as defined below) are currently
outstanding shares held by EndoSonics. No new shares of CVD Common Stock will be
issued by CVD in connection with the Merger.
 
     Cardiometrics stockholders are urged to read carefully the CVD Prospectus
attached to this Proxy Statement/Prospectus as Appendix G for further
information regarding CVD Common Stock to be transferred to them upon
consummation of the Merger. "CVD" refers to CardioVascular Dynamics, Inc., a
Delaware corporation. CVD was incorporated in California in 1992 and
reincorporated in Delaware in 1993. CVD's principal executive offices are
located at 13900 Alton Parkway, Suite 122, Irvine, California 92718. Its
telephone number is (714) 457-9546.
 
  Merger Sub
 
     "Merger Sub" refers to River Acquisition Corporation, a Delaware
corporation and wholly-owned subsidiary of EndoSonics, formed solely for the
purpose of the Merger. Merger Sub's principal executive offices are located at
2870 Kilgore Road, Rancho Cordova, California 95670. Its telephone number is
(916) 638-8008.
 
THE MERGER
 
     EndoSonics, Merger Sub and Cardiometrics have entered into an Agreement and
Plan of Reorganization, dated as of January 26, 1997, as subsequently amended
(the "Reorganization Agreement"), a copy of which is attached hereto as Appendix
A, whereby Merger Sub will be merged with and into Cardiometrics (the "Merger"),
resulting in Cardiometrics becoming a wholly-owned subsidiary of EndoSonics. See
"The Merger and Related Transactions."
 
     The Merger Consideration
 
     Upon consummation of the Merger, each outstanding share of Cardiometrics
Common Stock will be converted, without any action on the part of the holder
thereof, into the right to receive the following (the "Merger Consideration"):
(i) .35 shares of EndoSonics Common Stock (the "EndoSonics Exchange Ratio");
(ii) $3.00 in cash (the "Cash Consideration"); and (iii) at least .1364 but no
more than .19 shares of CVD Common Stock (adjusted as set forth in the following
sentence, the "CVD Exchange Ratio"). If, based on the average closing prices of
EndoSonics Common Stock and CVD Common Stock for the ten trading days
immediately preceding (and including) the third trading day prior to the
Cardiometrics Meeting and using a CVD Exchange Ratio of .1364, the Merger
Consideration would be less than $8.00, the CVD Exchange Ratio will be increased
from .1364 such that the Merger Consideration shall equal $8.00, but in no event
shall the CVD Exchange Ratio exceed .19. As a result, because the Reorganization
Agreement does not contain a minimum value for the Merger Consideration or allow
Cardiometrics to terminate the Merger if the Merger Consideration falls below a
specified value, the value of the Merger Consideration may be lower than $8.00
per share at the time of closing. Shares of Cardiometrics Common Stock held by
EndoSonics will be cancelled and extinguished without any conversion thereof.
The recent stock prices of each of EndoSonics and CVD have been highly volatile.
Such volatility could affect the value of the Merger Consideration and the CVD
Exchange Ratio. For current information on the value of the Merger Consideration
and the CVD Exchange Ratio, stockholders are encouraged to call Cardiometrics at
(800) 440-2356. Cash will be
 
                                        2

paid in lieu of fractional shares. Based upon the capitalization of
Cardiometrics and EndoSonics as of May 30, 1997, including the cancellation of
the 300,000 shares of Cardiometrics Common Stock held by EndoSonics, the
stockholders of Cardiometrics will own EndoSonics Common Stock representing
approximately 14.7% of the EndoSonics Common Stock outstanding immediately after
consummation of the Merger. See "The Merger and Related Transactions -- The
Merger Consideration -- Conversion of Shares."
 
     Also, each outstanding stock option (a "Cardiometrics Option") under the
Cardiometrics 1985 Stock Option Plan, 1995 Stock Option Plan and 1995 Stock
Incentive Plan (collectively, the "Cardiometrics Option Plans") 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
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. Within five days following the effectiveness of the
Merger, EndoSonics will file a Registration Statement on Form S-8 with the
Commission with respect to the shares of EndoSonics Common Stock issuable upon
exercise of assumed Cardiometrics Options originally issued under the
Cardiometrics Option Plans. See "The Merger and Related Transactions -- The
Merger Consideration -- Treatment of Options."
 
     Each outstanding warrant to purchase shares of Cardiometrics Common Stock,
pursuant to its terms, will be assumed by EndoSonics upon the consummation of
the Merger and upon payment of the same aggregate exercise price for such
warrant prior to the Merger be exercisable for the Merger Consideration
multiplied by the number of shares of Cardiometrics Common Stock subject to such
warrant immediately prior to the Merger. See "The Merger and Related
Transactions -- The Merger Consideration -- Treatment of Warrants."
 
     The shares of EndoSonics Common Stock outstanding prior to the Merger will
remain unchanged by the Merger, except for dilution resulting from the Merger.
The shares of CVD Common Stock outstanding prior to the Merger will remain
unchanged by the Merger, except for the increased number of shares of CVD Common
Stock available for immediate public sale as a result of the transfer of shares
from EndoSonics to Cardiometrics stockholders as a result of the Merger. See the
CVD Prospectus attached hereto as Appendix G.
 
THE AGREEMENT AND PLAN OF REORGANIZATION
 
  Representations and Covenants
 
     Under the Reorganization Agreement, EndoSonics and Cardiometrics made a
number of representations regarding their respective capital structures,
operations, financial conditions and other matters and also made certain
covenants regarding their respective conduct prior to the consummation of the
Merger or the termination of the Reorganization Agreement. In addition,
EndoSonics has covenanted that it will use reasonable efforts to prevent CVD
from taking certain actions without the prior written consent of Cardiometrics.
See "The Merger and Related Transactions -- The Agreement and Plan of
Reorganization -- Representations, Warranties and Covenants."
 
                                        3
<PAGE>   15
 
  No Solicitation of Transactions
 
     Cardiometrics has agreed not to, directly or indirectly, solicit or
initiate discussions with, encourage or engage in negotiations with, or disclose
any nonpublic information relating to Cardiometrics to any person relating to a
possible acquisition of Cardiometrics, except that, if the Board of Directors of
Cardiometrics (the "Cardiometrics Board") receives an unsolicited proposal that
is financially more favorable to its stockholders than the Merger (a "Superior
Proposal"), and the Cardiometrics Board determines in good faith after
consultation with outside legal counsel that it is necessary for the
Cardiometrics Board to comply with its fiduciary duties to stockholders under
applicable law, then the Cardiometrics Board will not be prevented from taking
such other actions as are consistent with its fiduciary obligations. However,
should the Cardiometrics Board accept, approve or recommend to the Cardiometrics
stockholders such an offer, Cardiometrics must promptly pay to EndoSonics a
$3,500,000 termination fee (the "Termination Fee"). See "The Merger and Related
Transactions -- The Agreement and Plan of Reorganization -- No Solicitation of
Transactions."
 
  Conditions to the Merger
 
     In addition to the requirement that the requisite approval of the
Cardiometrics stockholders be received, consummation of the Merger is subject to
a number of other conditions that, if not satisfied or waived, may cause the
Merger not to be consummated and the Reorganization Agreement to be terminated.
Each party's obligation to consummate the Merger is conditioned on, among other
things, continued effectiveness of the Registration Statement, the accuracy of
the other party's representations, the other party's performance of its
covenants, the absence of a material adverse change with respect to the other
party, and the absence of legal action preventing the consummation of the
Merger. To the extent any material conditions are waived, Cardiometrics will
amend this Proxy Statement/Prospectus and resolicit stockholder approval prior
to consummation of the Merger. See "The Merger and Related Transactions -- The
Agreement and Plan of Reorganization -- Conditions to the Merger."
 
  Termination or Amendment
 
     At any time prior to the Effective Time, the Reorganization Agreement may
be terminated (a) by mutual agreement of EndoSonics and Cardiometrics or (b) by
either EndoSonics or Cardiometrics if (i) without fault of the terminating
party, the closing of the Merger has not occurred on or before September 30,
1997, (ii) there is a breach by the other party of a representation, warranty or
obligation set forth in the Reorganization Agreement in any material respect and
such breach is not cured within ten (10) business days after written notice from
the other, (iii) a Trigger Event or Takeover Proposal (each, as defined in "The
Merger and Related Transactions -- The Agreement and Plan of
Reorganization -- Amendments, Termination and Waivers" and "-- No Solicitations
of Transactions," respectively) shall have occurred and the Cardiometrics Board
in connection therewith withdraws or modifies its approval and recommendation of
the Reorganization Agreement after determining that to cause Cardiometrics to
proceed with the Merger would not be consistent with the Cardiometrics Board's
fiduciary duty to the stockholders of Cardiometrics, (iv) there is a final,
non-appealable order of a court or other competent authority in effect
preventing consummation of the Merger or (v) the required approval of the
stockholders of Cardiometrics is not obtained at the Cardiometrics Meeting.
 
     The Reorganization Agreement may be terminated by EndoSonics prior to the
Effective Time if (i) the Cardiometrics Board withdraws or modifies its
recommendation of the Reorganization Agreement or the Merger in a manner adverse
to EndoSonics or shall have resolved to do any of the foregoing or (ii) for any
reason, Cardiometrics fails to call and hold the Cardiometrics Meeting by
September 30, 1997.
 
     The Reorganization Agreement may be amended by EndoSonics and Cardiometrics
at any time before or after approval by the Cardiometrics stockholders, except
that, after such approval, no amendment may be made which (i) alters or changes
the amount or kind of consideration to be received on conversion of the
Cardiometrics Common Stock, (ii) alters or changes any term of the Certificate
of Incorporation of the surviving corporation to be effected by the Merger, or
(iii) alters or changes any of the terms and conditions of the Reorganization
Agreement if such alteration or change
 
                                        4
<PAGE>   16
 
would adversely affect the holders of Cardiometrics Common Stock or Merger Sub
Common Stock. See "The Merger and Related Transactions -- The Agreement and Plan
of Reorganization -- Amendments, Termination and Waivers."
 
  Fees and Expenses; Termination Fee
 
     Whether or not the Merger is consummated, all costs and expenses incurred
in connection with the Reorganization Agreement and the Merger will be paid by
the party incurring the expense, except that certain printing and registration
fees will be shared equally. Notwithstanding the foregoing, in certain events,
if Cardiometrics terminates the Reorganization Agreement, Cardiometrics must
promptly pay to EndoSonics $1,500,000 for the out-of-pocket costs and expenses
incurred by EndoSonics or in certain other cases, the cash sum of $3,500,000.
See "The Merger and Related Transactions -- The Agreement and Plan of
Reorganization -- Fees and Expenses; Termination Fee."
 
VOTING AGREEMENTS
 
     In connection with the Merger, certain stockholders of Cardiometrics have
entered into voting agreements, as subsequently amended, with EndoSonics, the
forms of which are attached as Appendix D hereto (the "Voting Agreements"). The
terms of the Voting Agreements provide that each of such stockholders will vote
certain shares of Cardiometrics Common Stock beneficially owned by such
stockholders in favor of the approval of the Reorganization Agreement and
consummation of the Merger and against any competing proposals. The Voting
Agreements are accompanied by irrevocable proxies (the "Proxies") whereby
certain stockholders of Cardiometrics provide to EndoSonics the right to vote
certain of the shares beneficially owned by them on the proposals relating to
the Reorganization Agreement and the Merger at the Cardiometrics Meeting and any
competing proposal at a Cardiometrics stockholder meeting. As of the Record
Date, holders of approximately 5.7% of the shares of Cardiometrics Common Stock
entitled to vote at the Cardiometrics Meeting have entered into the Voting
Agreements and Proxies. See "The Merger and Related Transactions -- Related
Agreements -- Voting Agreements."
 
STOCK OPTION AGREEMENT
 
     EndoSonics and Cardiometrics have entered into a Stock Option Agreement,
dated as of January 26, 1997 (the "Stock Option Agreement"), a copy of which is
attached as Appendix F hereto, pursuant to which EndoSonics has the right, under
certain circumstances, to acquire up to 1,379,717 shares of authorized and
unissued Cardiometrics Common Stock (or approximately 19.9% of the outstanding
Cardiometrics Common Stock prior to such issuance) at a price per share of $9.00
(the "Stock Option"). 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. See "The Merger and
Related Transactions -- Related Agreements -- Stock Option Agreement."
 
REASONS FOR THE MERGER
 
     The Boards of Directors of each of EndoSonics and Cardiometrics have
identified several potential benefits of the Merger that they believe will
contribute to the success of EndoSonics and Cardiometrics (together, the
"Combined Company"). The Combined Company is expected to, among other things,
enhance its competitiveness by offering a broader range of products and devices
for assessing and treating coronary artery and other vascular disease and to
benefit from operating cost reductions through consolidation and integration of
certain manufacturing, distribution, sales and administrative operations and
functions. However, each Board has also recognized that the potential benefits
of the Merger may not be realized and that there are a number of other risks
related to the Merger. See "Risk Factors," "The Merger and Related
Transactions -- Background of the Merger and "-- Reasons for the Merger."

OPINION OF CARDIOMETRICS' FINANCIAL ADVISOR
 
     Dillon, Read & Co. Inc. ("Dillon Read") delivered to the Cardiometrics
Board a written opinion, dated January 26, 1997 (the "Dillon Read Opinion"),
that, as of such date, the consideration to have been received by the holders of
Cardiometrics Common Stock pursuant to the terms of the Agreement and Plan of
Reorganization, as it existed prior to its amendment, was fair, from a financial
point of view, to such stockholders. The full text of the opinion of Dillon
Read, dated January 26, 1997, is attached as Appendix C to this Proxy
Statement/Prospectus. Cardiometrics stockholders are urged to read the January
26, 1997 opinion in its entirety. The opinion of Dillon Read was delivered
before the Reorganization Agreement was amended on May 20, 1997 to modify in
certain respects the consideration to be received by holders of Cardiometrics
Common Stock in the Merger. Cardiometrics stockholders are advised that the
Dillon Read Opinion does not speak to the Merger Consideration, which the
Cardiometrics Board considered to be more favorable than the original merger
consideration. See "The Merger and Related Transactions -- Background of the
Merger" and " -- Fairness Opinion of Dillon Read" for additional information
regarding Dillon Read's fairness opinion and the factors considered by the
Cardiometrics Board in not requesting an updated fairness opinion from Dillon
Read in connection with the May 20, 1997 amendment of the Reorganization
Agreement.
 
RECOMMENDATION OF CARDIOMETRICS' BOARD OF DIRECTORS
 
     THE CARDIOMETRICS BOARD OF DIRECTORS (I) BELIEVES THE TERMS AND CONDITIONS
OF THE REORGANIZATION AGREEMENT AND THE PROPOSED MERGER ARE FAIR TO, AND IN THE
BEST INTERESTS OF, CARDIOMETRICS STOCKHOLDERS, (II) HAS APPROVED THE TERMS OF
THE REORGANIZATION AGREEMENT AND THE MERGER AND (III) RECOMMENDS THAT
CARDIOMETRICS STOCKHOLDERS VOTE FOR THE APPROVAL OF THE REORGANIZATION AGREEMENT
AND CONSUMMATION OF THE MERGER. THE PRIMARY FACTORS CONSIDERED AND RELIED UPON
BY THE CARDIOMETRICS BOARD OF DIRECTORS IN REACHING ITS RECOMMENDATION ARE
REFERRED TO IN "THE MERGER AND RELATED TRANSACTIONS -- BACKGROUND OF THE MERGER"
AND "-- REASONS FOR THE MERGER."
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     In considering the recommendation of the Cardiometrics Board with respect
to the Reorganization Agreement and the Merger, the Cardiometrics stockholders
should be aware that certain directors and officers of Cardiometrics have
interests in the Merger that may present them with potential conflicts of
interest. See "The Merger and Related Transactions -- Interests of Certain
Persons in the Merger."
 
RISK FACTORS
 
     In considering whether to approve the Reorganization Agreement and the
consummation of the Merger, Cardiometrics stockholders should carefully review
and consider the information contained below under the caption "Risk Factors,"
as well as the factors set forth under the heading "Risk Factors" in EndoSonics'
Annual Report on Form 10-K, as amended, for the year ended December 31, 1996
incorporated by reference into this Proxy Statement/Prospectus, and the factors
set forth in "Risk Factors" in the CVD Prospectus, a copy of which is attached
hereto as Appendix G.
 
THE CARDIOMETRICS MEETING
 
  Date, Time, Place and Purpose of the Cardiometrics Meeting
 
     The Cardiometrics Meeting will be held on July 23, 1997, at 10:00 a.m.,
local time, at Cardiometrics' Mountain View facilities located at 645 Clyde
Avenue, Mountain View, California. At the Cardiometrics Meeting, stockholders of
record of Cardiometrics will be asked to consider and vote upon a proposal to
approve the Reorganization Agreement and the consummation of the Merger and upon
any other matter that may properly come before the Cardiometrics Meeting.

  Record Date; Shares Entitled to Vote
 
     Only holders of record of Cardiometrics Common Stock on May 30, 1997 (the
"Record Date") are entitled to notice of and to vote at the Cardiometrics
Meeting. At the close of business on the Record Date, there were outstanding and
entitled to vote 6,982,173 shares of Cardiometrics Common Stock, each of which
will be entitled to one vote on each matter to be acted upon.
 
  Vote Required
 
     Approval of the Reorganization Agreement and the consummation of the Merger
will require the affirmative vote of the holders of a majority of the
outstanding shares of Cardiometrics Common Stock entitled to vote. As of the
Record Date, Cardiometrics' directors and executive officers (and their
affiliates), as a group, beneficially owned 401,332 shares (exclusive of any
shares issuable upon the exercise of options or warrants unexercised as of such
date), or approximately 5.7% of the 6,982,173 shares of Cardiometrics Common
Stock that were issued and outstanding as of such date. Certain stockholders of
Cardiometrics have entered into Voting Agreements and have delivered irrevocable
proxies obligating them to vote certain shares beneficially owned by them in
favor of the Reorganization Agreement and the consummation of the Merger. As of
the Record Date, such stockholders, constituting all executive officers and
certain directors of Cardiometrics and their affiliates, as a group beneficially
owned 401,332 shares (exclusive of any shares issuable upon the exercise of
options unexercised as of such date) of Cardiometrics Common Stock (constituting
approximately 5.7% of the 6,982,173 shares of Cardiometrics Common Stock then
outstanding). See "The Merger and Related Transactions -- Related
Agreements -- Voting Agreements."
 
  Quorum; Abstentions and Broker Non-Votes
 
     The required quorum for the transaction of business at the Cardiometrics
Meeting is a majority of the shares of Cardiometrics Common Stock issued and
outstanding as of the Record Date. Abstentions and broker non-votes each will be
included in determining the number of shares present and voting at the meeting
for the purpose of determining the presence of a quorum, but will have the same
effect as votes against the Reorganization Agreement and the consummation of the
Merger. THE ACTIONS PROPOSED IN THIS PROXY STATEMENT/PROSPECTUS ARE NOT MATTERS
THAT CAN BE VOTED ON BY BROKERS HOLDING SHARES FOR BENEFICIAL OWNERS WITHOUT THE
OWNERS' SPECIFIC INSTRUCTIONS. ACCORDINGLY, ALL BENEFICIAL OWNERS OF
CARDIOMETRICS COMMON STOCK ARE URGED TO RETURN THE ENCLOSED PROXY CARD MARKED TO
INDICATE THEIR VOTES.
 
  Appraisal Rights
 
     In connection with the Merger, a holder of shares of Cardiometrics Common
Stock will be entitled to demand appraisal rights in respect of such shares of
Cardiometrics Common Stock subject to satisfaction by such stockholder of the
conditions for appraisal rights established by Section 262 of the Delaware
General Corporation Law (the "DGCL"). Section 262 of the DGCL is set forth in
full in Appendix B hereto. See "The Merger and Related Transactions -- Appraisal
Rights."
 
CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
  Tax Consequences to Cardiometrics Stockholders
 
     The Merger will constitute a fully taxable transaction rather than a
tax-free reorganization. Each Cardiometrics stockholder will recognize gain or
loss upon the Merger based on the difference between (i) the sum of the cash,
the fair market value of the EndoSonics Common Stock and the fair market value
of the CVD Common Stock received by the Cardiometrics stockholder in the Merger,
and (ii) such stockholder's tax basis in his or her shares of Cardiometrics
Common Stock exchanged in the Merger. Except in the case of certain stockholders
who have acquired their shares of Cardiometrics Common Stock through the
exercise of incentive stock options (as discussed in "The Merger and Related
Transactions -- Certain Federal Income Tax Considerations -- Tax Consequences to
Holders of Cardiometrics Options"), such gain or loss will be a capital gain or
loss if the exchanged
 
                                        7
<PAGE>   19
 
Cardiometrics Common Stock is a capital asset in the hands of the Cardiometrics
stockholder and will be long-term capital gain or loss if such stockholder has
held his or her shares of Cardiometrics Common Stock for more than one year.
 
  Tax Consequences to Holders of Cardiometrics Options
 
     Upon the conversion in part of each outstanding Cardiometrics Option into
the right to receive cash and CVD Common Stock in the Merger, each holder of
Cardiometrics Options will recognize ordinary income in the amount of the cash
and the fair market value of the CVD Common Stock received with respect to that
option. Such income will constitute wages subject to EndoSonics' collection of
applicable federal and state income and employment withholding taxes.
 
     No income will be recognized for federal income tax purposes upon the
assumption of the Cardiometrics Options by EndoSonics.
 
     CARDIOMETRICS STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS
TO THE SPECIFIC TAX CONSEQUENCES OF THE MERGER, INCLUDING THE APPLICABLE
FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO THEM OF THE MERGER. See
"The Merger and Related Transactions -- Certain Federal Income Tax
Considerations."
 
ACCOUNTING TREATMENT
 
     The Merger will be accounted for under the purchase method of accounting in
accordance with generally accepted accounting principles, whereby the purchase
price will be allocated based on the fair value of the assets acquired and
liabilities assumed. Such allocation will be made based upon valuations that
have not been finalized. It is anticipated that a significant portion of the
purchase price will be allocated to in-process research and development which
will result in a charge to EndoSonics' consolidated statement of operations of
approximately $41.1 million in the fiscal quarter in which the Merger closes.
The amount of the estimated charge is based on a preliminary valuation and the
actual amount could vary significantly upon completion of the final valuation.

(1) Represents the equivalent of one share of Cardiometrics Common Stock
    calculated by adding
     (i) the product of multiplying the sale price per share of EndoSonics
    Common Stock by the EndoSonics Exchange Ratio, (ii) the product of
    multiplying the sale price per share of CVD Common Stock by the CVD Exchange
    Ratio and (iii) $3.00.
 
     Although the EndoSonics Exchange Ratio is fixed at 0.35, because the CVD
Exchange Ratio, initially fixed at 0.1364, is adjustable (but with such
adjustment limited such that the CVD Exchange Ratio shall not exceed 0.19), and
because the market prices of EndoSonics Common Stock and CVD Common Stock are
subject to fluctuation, the number of shares of CVD Common Stock that holders of
Cardiometrics Common Stock will receive in the Merger may change prior to the
Merger and the market value of the shares of EndoSonics Common Stock and CVD
Common Stock that holders of Cardiometrics Common Stock will receive in the
Merger may increase or decrease prior to and following the Merger. Stockholders
are urged to obtain current market quotations for EndoSonics Common Stock, CVD
Common Stock and Cardiometrics Common Stock. For current information on the
value of the Merger Consideration and the CVD Exchange Ratio, stockholders are
encouraged to call Cardiometrics at (800) 440-2356. No assurance can be given as
to the future prices or markets for EndoSonics Common Stock, CVD Common Stock or
Cardiometrics Common Stock. Cardiometrics stockholders should obtain and
consider recent trading prices of EndoSonics Common Stock and CVD Common Stock
in determining whether to vote in favor of the Reorganization Agreement and the
consummation of the Merger.
 
NUMBER OF STOCKHOLDERS
 
     As of the Record Date, there were 99 stockholders of record who held shares
of Cardiometrics Common Stock (although Cardiometrics has been informed that
there are approximately 1,700 beneficial owners), as shown on the records of
Cardiometrics' transfer agent for such shares.

                                  RISK FACTORS
 
     The following risk factors should be considered by holders of Cardiometrics
Common Stock in evaluating whether to approve the Reorganization Agreement and
the consummation of the Merger and thereby become holders of EndoSonics Common
Stock and CVD Common Stock. These risks should be read in conjunction with the
other information included and incorporated by reference in this Proxy
Statement/Prospectus, including, without limitation, the factors set forth under
the heading "Risk Factors" in EndoSonics' Annual Report on Form 10-K, as
amended, for the year ended December 31, 1996 incorporated by reference into
this Proxy Statement/Prospectus, and the factors set forth in "Risk Factors" in
the CVD Prospectus, a copy of which is attached hereto as Appendix G.
 
RISKS ASSOCIATED WITH THE MERGER
 
  Uncertainties Relating to Integration of Operations
 
     EndoSonics and Cardiometrics have entered into the Reorganization Agreement
with the expectation that the Merger will result in operating and strategic
benefits, including operating cost reductions and product development, marketing
and sales synergies. The anticipated benefits of the Merger may not be achieved
unless the operations of Cardiometrics are successfully combined with those of
EndoSonics in a coordinated, timely and efficient manner, and there can be no
assurance this will occur. The transition to a combined company will require
substantial attention from management. The diversion of the attention of
management and any difficulties encountered in the transition process could have
an adverse impact on the revenues and operating results of the Combined Company.
The combination of the two companies will also require integration of the
companies' product offerings and the coordination of their research and
development and sales and marketing efforts. The difficulties of assimilation
may be increased by the necessity of integrating personnel with disparate
business backgrounds and combining two different corporate cultures. In
addition, the process of combining the two organizations could cause the
interruption of, or a loss of momentum in, the activities of either or both of
the companies' businesses, which could have an adverse effect on their combined
operations. There can be no assurance that either company will retain its key
management, technical, sales and marketing personnel or that the Combined
Company will realize any of the other anticipated benefits of the Merger.
Failure to achieve the anticipated benefits of the Merger or to successfully
integrate the operations of the companies could have a material adverse effect
upon the business, operating results and financial condition of the Combined
Company. Even if the benefits of the Merger are achieved and the two companies'
operations are successfully integrated, there can be no assurance that future
the operating results and financial condition of the Combined Company will not
be adversely affected by any number of economic, market or other factors that
are not related to the Merger.
 
  Effect of the Merger on Customers
 
     The announcement and consummation of the Merger could cause customers and
potential customers of Cardiometrics or EndoSonics to delay or cancel orders for
products as a result of customer concerns and uncertainty over product
evolution, integration and support of the Combined Company's products. Such a
delay or cancellation of orders could have a material adverse effect on the
business, results of operations and financial condition of either or both of
Cardiometrics or EndoSonics.
 
  Transaction Expenses; Costs of Integration
 
     EndoSonics and Cardiometrics estimate they will together incur direct
transaction costs (including investment banking, legal, accounting, registration
and printing fees) of approximately $3.0 million associated with the Merger. In
addition, following the Merger, EndoSonics expects to incur a significant
additional charge to operations of approximately $6,500,000 to reflect the costs
associated with integrating the two companies, including, without limitation,
severance and relocation costs. These estimates are preliminary and subject to
change. These costs are expected to be charged against income of EndoSonics in
the fiscal quarter ending September 30, 1997. The Merger will have a short-term
adverse effect on the net income of EndoSonics due to the aforementioned
expenses. There can be
 
                                       15
<PAGE>   27
 
no assurance that EndoSonics will not incur additional material charges in
subsequent quarters to reflect additional costs associated with the Merger.
 
  Shares Eligible for Future Sale
 
     EndoSonics will issue approximately 2,339,000 shares of EndoSonics Common
Stock in the Merger. In general, such shares will be freely tradeable following
the Merger. The sale of any of these shares may cause substantial fluctuations
in the price of EndoSonics Common Stock over short time periods.
 
     Also, in the Merger, assuming a CVD Exchange Ratio of .1364, EndoSonics
will transfer approximately 911,000 shares of CVD Common Stock currently held by
EndoSonics to the current Cardiometrics stockholders and optionholders. Such
shares are not currently freely tradeable by EndoSonics, but will become freely
tradeable by the former Cardiometrics stockholders following the Merger. In
addition, EndoSonics has announced its intention to declare, following the
Merger, a dividend of .04 shares of CVD Common Stock held by it for each share
of EndoSonics Common Stock. The sale or anticipation of the sale of any of these
shares of CVD Common Stock currently held by EndoSonics and which are not
currently freely tradeable by EndoSonics may cause substantial fluctuations in
the price of CVD Common Stock.
 
  Volatility of Stock Prices; Value of Consideration Depends on Price of
EndoSonics and CVD Common Stock
 
     The recent prices of each of EndoSonics Common Stock, CVD Common Stock and
Cardiometrics Common Stock have been highly volatile. Such stock prices can be
expected to continue to experience substantial volatility in response to actual
or anticipated quarterly variations in operating results, announcements of
technological innovations or new products by EndoSonics, CVD or Cardiometrics
(as applicable) or their respective competitors, developments related to patents
or other intellectual property rights, developments in EndoSonics', CVD's or
Cardiometrics' (as applicable) relationships with their respective customers,
distributors or suppliers, acquisitions or divestitures of other companies in
the health care industry, and other events or factors. In addition, any
shortfall or changes in revenue, gross margins, earnings, or other financial
results from analysts' expectations could cause the price of EndoSonics', CVD's
or Cardiometrics' (as applicable) Common Stock to fluctuate significantly. In
recent years, the stock market in general has experienced extreme price and
volume fluctuations, which have particularly affected the market price of many
technology and health care companies and which have often been unrelated to the
operating performance of those companies. These broad market fluctuations may
adversely affect the market price of EndoSonics', CVD's or Cardiometrics' (as
applicable) Common Stock. In addition, the distribution of CVD's Common Stock by
EndoSonics in connection with the Merger could adversely affect the market price
of CVD's Common Stock.
 
     Fluctuations in the prices of EndoSonics Common Stock and CVD Common Stock
could affect the value of the Merger Consideration and the CVD Exchange Ratio.
Under the terms of the Reorganization Agreement, the shares of Cardiometrics
Common Stock issued and outstanding at the Effective Time will be converted into
the right to receive shares of EndoSonics Common Stock, CVD Common Stock and
cash. While the CVD Exchange Ratio will be adjusted under certain circumstances
based on the closing sale prices of EndoSonics Common Stock and CVD Common Stock
during the ten trading days immediately preceding (and including) the third
trading day prior to the Cardiometrics Meeting, the value of the consideration
to be received by holders of Cardiometrics Common Stock upon the Merger will
depend on the values of EndoSonics Common Stock and CVD Common Stock. See "The
Merger and Related Transactions -- The Merger Consideration -- Conversion of
Shares." There can be no assurance that the market price of EndoSonics Common
Stock and CVD Common Stock on and after the Effective Time will not be higher or
lower than their respective prices on the last trading day prior to the public
announcement of the Merger, the third trading day prior to the Cardiometrics
Meeting, when the CVD Exchange Ratio will be fixed, or any other date.
Cardiometrics stockholders should obtain and consider recent trading prices of
EndoSonics Common Stock and CVD Common
 
                                       16

Stock in determining whether to vote in favor of the Reorganization Agreement
and the consummation of the Merger. For current information on the value of the
Merger Consideration and the CVD Exchange Ratio, stockholders are encouraged to
call Cardiometrics at (800) 440-2356.
 
  Uncertain Outcomes of Pending Litigation
 
     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. There can be no
assurance that such litigation will not delay or enjoin the consummation of the
Merger, result in rescission of the Merger or require the payment of damages.
 
  Potential Conflicts of Interest
 
     In considering the recommendation of the Cardiometrics Board with respect
to the Merger, stockholders of Cardiometrics should be aware that certain
officers and directors of Cardiometrics have interests in the Merger that are in
addition to the interests of Cardiometrics' stockholders generally.
Cardiometrics Change in Control Severance Plan provides severance benefits for
eligible employees of Cardiometrics, including the officers of the Company, one
of whom, Dr. Nassi, is also a member of the Cardiometrics Board, upon an
Involuntary Termination (as defined in such plan) of employment within the 12
month period following a Change in Control of Cardiometrics, which as defined in
the Severance Plan, includes the Merger. Also, pursuant to the terms of the
Cardiometrics Option Plans, all of Cardiometrics' outstanding stock options and
shares purchased under options, including outstanding options and shares held by
Cardiometrics' officers and directors, will vest in full upon the Merger.
Furthermore, Cardiometrics and Dr. Nassi have entered into an Employment
Agreement which provides for continuation of Dr. Nassi's salary and benefits for
a 12-month period in the event that his employment is terminated without cause,
provided that Dr. Nassi provides certain consulting services to the Company and
provided, further, that the severance payments will cease after six months if
Dr. Nassi obtains full-time employment. Also, prior to the execution of the
Reorganization Agreement, certain officers and directors of EndoSonics held
discussions with Dr. Nassi regarding his joining the Board of Directors of
EndoSonics following the Effective Time. Immediately following the execution of
the Reorganization Agreement, EndoSonics publicly announced that it expected
that Dr. Nassi would join the EndoSonics Board of Directors. On March 10, 1997,
Dr. Nassi and EndoSonics agreed to the terms of a consulting relationship to be
effective upon the consummation of the Merger. Furthermore, the Reorganization
Agreement provides that, after the Effective Time, the surviving corporation
shall, to the fullest extent permitted under the laws of the State of Delaware
or the Certificate of Incorporation or Bylaws of the surviving corporation,
indemnify and hold harmless each director of the surviving corporation made, or
threatened to be made, a party to an action or proceeding, whether criminal,
civil, administrative or investigative, by reason of being a director of the
corporation or a predecessor corporation. See "The Merger and Related
Transactions -- Interests of Certain Persons in the Merger." In addition, the
Reorganization Agreement provides that after the Effective Time, EndoSonics
will, and will cause Cardiometrics to, indemnify, defend and hold harmless the
present and former officers, directors, employees and agents of Cardiometrics
(the "Indemnified Parties") in respect of acts or omissions occurring on or
prior to the Effective Time. Also, for four years after the Effective Time,
EndoSonics will either (i) maintain at least $100,000,000 in cash, marketable
 
                                       17
<PAGE>   29
 
securities and unrestricted lines of credit to be available to indemnify the
Indemnified Parties or (ii) cause Cardiometrics to use its best efforts to
provide directors' liability insurance for acts or omissions occurring on or
prior to the Effective Time. See "The Merger and Related Transactions -- The
Agreement and Plan of Reorganization -- Indemnification and Insurance." The
Cardiometrics Board was aware of these interests and considered them, among
other matters, in approving the Merger Agreement.
 
RISK FACTORS THAT MAY AFFECT FUTURE RESULTS OF ENDOSONICS
 
     EndoSonics operates in a highly competitive environment that involves a
number of risks, some of which are beyond EndoSonics' control. The following
discussion highlights some of these risks.
 
     History of Operating Losses; Anticipated Future Losses.  EndoSonics was
founded in 1984 and has experienced annual operating losses since its inception.
EndoSonics' accumulated deficit at March 31, 1997 was approximately $57.5
million. EndoSonics expects to continue to incur operating losses through 1997
and there can be no assurance that EndoSonics will ever be able to achieve or
sustain profitability in the future. Although EndoSonics believes that its
existing cash, cash equivalents and short-term investments will be sufficient to
meet its liquidity requirements through 1998, there can be no assurance that
EndoSonics will not require additional financing or that such financing, if
required, will be available on satisfactory terms, if at all.
 
     Acquisitions.  EndoSonics' business strategy includes acquiring related
businesses, products or technologies. In January 1997, EndoSonics entered into
an agreement to acquire Cardiometrics through the merger of a wholly-owned
subsidiary of EndoSonics with and into Cardiometrics, with Cardiometrics
surviving as a wholly-owned subsidiary of EndoSonics. EndoSonics expects to
incur an approximate $40 million dollar in-process research and development
charge as a result of the such acquisition. EndoSonics expects that it may
pursue additional acquisitions in the future. Any future acquisitions may result
in potentially dilutive issuances of equity securities, the write-off of in
process research and development, the incurrence of debt and contingent
liabilities and amortization expenses related to intangible assets acquired, any
of which could materially adversely affect EndoSonics' business, financial
condition and results of operations. In particular, if EndoSonics is unable to
use the "pooling of interests" method of accounting, EndoSonics will be required
to amortize any intangible assets acquired in connection with any additional
acquisitions and the amortization periods for such costs will be over the useful
lives of such assets, which range from two years to eight years. Additionally,
unanticipated expenses may be incurred relating to the integration of
technologies and research and development and administrative functions. Any
acquisition will involve numerous risks, including difficulties in the
assimilation of the acquired company's employees, operations and products,
uncertainties associated with operating in new markets and working with new
customers, the potential loss of the acquired company's key employees as well as
the costs associated with completing the acquisition and integrating the
acquired company.
 
     Uncertainty of Market Acceptance.  Although external ultrasound imaging and
balloon angioplasty are widely used technologies, the use of IVUS imaging in
connection with interventional cardiology is relatively new. The commercial
success of EndoSonics' products will depend upon their acceptance by the medical
community as a useful, cost-effective component of interventional cardiovascular
and peripheral vascular procedures. IVUS imaging is used in conjunction with
angioplasty and other intravascular procedures such as vascular stenting.
Accordingly, the medical community must determine that the information obtained
from the use of EndoSonics' ultrasound products will increase the safety or
effectiveness or lower the overall cost of the care being provided and that the
value of such information justifies the incremental expense of obtaining IVUS
imaging. In addition, market acceptance of EndoSonics' combination balloon
angioplasty/IVUS imaging catheters will depend, among other things, on a
determination by the medical community that the efficacy of the therapeutic
component of EndoSonics' combination catheters is at least comparable to that of
competing non-imaging angioplasty catheters and other types of therapy. Although
IVUS imaging devices have been available for over ten years, the market for such
products has remained relatively small. Although
 
                                       18
<PAGE>   30
 
EndoSonics believes the benefits of IVUS imaging can be demonstrated, there can
be no assurance that the benefits will be considered sufficient by the medical
community to enable EndoSonics' products to achieve widespread market
acceptance. Failure of EndoSonics' products to achieve market acceptance would
have a material adverse effect on EndoSonics' business, financial condition and
results of operations.
 
     Dependence on Strategic Relationships; Reliance on Cordis.  In February
1996, EndoSonics and Cordis Corporation ("Cordis"), a subsidiary of Johnson &
Johnson, entered into an agreement pursuant to which Cordis was granted the
exclusive right to distribute EndoSonics' IVUS imaging products for coronary
applications in North America, Europe, Africa and the Middle East (the
"Exclusive Distribution Agreement"). The Exclusive Distribution Agreement
supersedes and replaces a prior distribution agreement between Cordis and
EndoSonics and a prior distribution agreement between Endosonics Nederland B.V.,
a wholly owned subsidiary of EndoSonics, and Cordis S.A. Cordis is obligated
during each year of the Exclusive Distribution Agreement to use reasonable
efforts to purchase certain minimum annual amounts of products from EndoSonics.
Subject to certain exceptions, Cordis' failure to meet the minimum annual
purchase amount during any year of the Exclusive Distribution Agreement shall
constitute a material breach of such agreement. Cordis is also obligated during
the term of the Exclusive Distribution Agreement to undertake certain efforts to
market, promote, distribute and sell EndoSonics' IVUS imaging products,
including the provision of adequate personnel and facilities, the maintenance of
sufficient inventory for demonstration purposes and the appointment of a United
States and European intracoronary ultrasound marketing manager to interface with
EndoSonics' United States and European clinical and support staff. The Exclusive
Distribution Agreement also contains standard representations and warranties of
each party and standard provisions regarding indemnification, service and
maintenance and confidentiality. Under the terms of the Exclusive Distribution
Agreement, Cordis shall purchase IVUS imaging products from EndoSonics at agreed
upon prices set forth in such agreement, which prices shall be jointly reviewed
by EndoSonics and Cordis every six months. The Exclusive Distribution Agreement
initially expires on December 31, 1998, but may be extended by the parties for
successive one year periods. The Company and Cordis are currently in discussions
with regard to amending the Exclusive Distribution Agreement to cover both South
America and Japan.
 
     In light of EndoSonics' exclusive distribution relationship with Cordis,
EndoSonics' revenue from sales of IVUS imaging products will depend
substantially on the distribution capabilities of Cordis. Further, in recent
years there has been significant consolidation among medical device suppliers as
the major suppliers have attempted to broaden their product lines in order to
focus on product configurations that address a given procedure or treatment and
in order to respond to cost pressures from health care providers. This
consolidation has made it increasingly difficult for smaller suppliers, such as
EndoSonics, to effectively distribute their products without a major
relationship with one of the major suppliers. There can be no assurance that
EndoSonics will be able to maintain its relationship with Cordis or replace
Cordis in the event EndoSonics' relationship with Cordis would be terminated. In
the event of such a termination, EndoSonics' ability to distribute its IVUS
imaging products would be materially adversely affected, which would have a
material adverse effect on EndoSonics' business, financial condition and results
of operations.
 
     Dependence on New Products; Rapid Technological Change.  The medical device
industry generally, and the IVUS imaging device market in particular, are
characterized by rapid technological change, changing customer needs, and
frequent new product introductions. EndoSonics' future success will depend upon
its ability to develop and introduce new products that address the increasingly
sophisticated needs of its customers. There can be no assurance that EndoSonics
will be successful in developing and marketing new products that achieve market
acceptance or that EndoSonics will not experience difficulties that could delay
or prevent the successful development, introduction and marketing of new
products.
 
     In October 1995, EndoSonics announced the receipt of approval from the FDA
to market its Five-64 diagnostic catheters, which are designed to enhance image
quality and reduce manufacturing cost
 
                                       19
<PAGE>   31
 
relative to EndoSonics' Oracle-Micro(TM) catheter line. EndoSonics introduced
the Five-64 diagnostic catheters in November 1995 and commenced commercial
shipments of these catheters in the first quarter of 1996. There can be no
assurance that EndoSonics' competitors will not succeed in developing or
marketing technologies and products that are more effective or commercially
attractive than any that are being developed by EndoSonics, or that such
competitors will not succeed in obtaining regulatory approval for introducing or
commercializing any such products prior to EndoSonics. Furthermore, there can be
no assurance that EndoSonics' products will not be rendered obsolete as a result
of future innovations.
 
     Dependence on International Sales.  EndoSonics derives, and expects to
continue to derive, a significant portion of its revenue from international
sales. In 1994, 1995 and 1996, EndoSonics' international sales were $5.4
million, $9.9 million and $16.9 million, respectively, or 67%, 58% and 69% of
total revenue. Therefore, a significant portion of EndoSonics' revenues will
continue to be subject to the risks associated with international sales,
including economic or political instability, shipping delays, changes in
applicable regulatory policies, fluctuations in foreign currency exchange rates
and various trade restrictions, all of which could have a significant impact on
EndoSonics' ability to deliver products on a competitive and timely basis.
Future imposition of, or significant increases in the level of, customs duties,
import quotas or other trade restrictions, could have an adverse effect on
EndoSonics' business, financial condition and results of operation. The
regulation of medical devices, particularly in the European Community, continues
to expand and there can be no assurance that new laws or regulations will not
have an adverse effect on EndoSonics.
 
     Limited Manufacturing Experience.  EndoSonics' success will depend in part
on its ability to manufacture its products in compliance with the FDA's Good
Manufacturing Practices ("GMP") regulations, ISO 9001 and other regulatory
requirements, in sufficient quantities and on a timely basis, while maintaining
product quality and acceptable manufacturing cost. In addition, EndoSonics
intends to establish an automated manufacturing process for its Five-64 catheter
line in Rancho Cordova, California. Manufacturers often encounter difficulties
in scaling up production of new products an intergrating automation equipment,
including problems involving production yields, quality control and assurance,
component supply and shortages of qualified personnel. EndoSonics' failure to
fully integrate automation into the manufacturing process for the Five-64
catheter line in a timely manner, or to timely increase production volumes of
the Five-64 catheter line, would materially adversely affect EndoSonics'
business, financial condition and results of operations. EndoSonics instituted
two voluntary product recalls in 1994 due to manufacturing defects in its
Visions(TM) IVUS imaging catheter line. There can be no assurance that defects
will not occur in EndoSonics' products in the future. Failure to increase
production volumes in a timely or cost-effective manner or to maintain
compliance with GMP, ISO 9001 or other regulatory requirements could have a
material adverse effect on EndoSonics' business, financial condition and results
of operations.
 
     EndoSonics purchases many standard and custom built components from
independent suppliers, and contracts with third parties for certain specialized
electronic component manufacturing processes. Most of these purchased components
and processes are available from more than one vendor. However, the
manufacturing of the connection points on the integrated circuit microchips is
currently performed by a single vendor. Although EndoSonics is in the process of
identifying alternative vendors, the qualification of additional or replacement
vendors for certain components or services is a lengthy process. Any supply
interruption from this single source vendor would have a material adverse effect
on EndoSonics' ability to manufacture its products until a new source of supply
was qualified and, as a result, could have an adverse effect on EndoSonics'
business, financial condition and results of operations.
 
     Limitations on Third-Party Reimbursement.  In the United States,
EndoSonics' products are purchased primarily by medical institutions, which then
bill various third-party payors, such as Medicare, Medicaid, and other
government programs and private insurance plans, for the health care services
provided to patients. Government agencies, private insurers and other payors
determine whether to provide coverage for a particular procedure and reimburse
hospitals for medical treatment at a fixed
 
                                       20
<PAGE>   32
 
rate based on the diagnosis-related group ("DRG") established by the U.S. Health
Care Financing Administration ("HCFA"). The fixed rate of reimbursement is based
on the procedure performed, and is unrelated to the specific devices used in
that procedure. If a procedure is not covered by a DRG, payors may deny
reimbursement. In addition, some payors may deny reimbursement if they determine
that the device used in a treatment was unnecessary, inappropriate or not
cost-effective, experimental or used for a non-approved indication. Currently,
there are no established DRGs covering diagnostic IVUS imaging procedures.
Reimbursement of balloon angioplasty procedures is covered under a DRG, but
because the amount of reimbursement is fixed, the amount of potential profit
relating to the procedure is reduced to the extent the physician performs
additional procedures such as IVUS imaging or uses a more expensive product
which combines IVUS imaging with therapeutic capabilities. Accordingly,
physicians must determine that the clinical benefits of IVUS imaging justify the
additional cost. Although EndoSonics believes that less invasive procedures
generally provide less costly overall therapies as compared to alternative
surgical procedures, there can be no assurance that reimbursement for such less
invasive procedures will continue to be available, or that future reimbursement
policies of payors will not adversely affect EndoSonics' ability to sell its
products on a profitable basis. Failure by hospitals and other users of
EndoSonics' products to obtain reimbursement from third-party payors, or changes
in government and private third-party payors' policies toward reimbursement for
procedures employing EndoSonics' products, would have a material adverse effect
on EndoSonics' business, financial condition and results of operations.
 
     The market for EndoSonics' products could be adversely affected by changes
in governmental and private third-party payors' policies. Capital costs for
medical equipment purchased by hospitals are currently reimbursed separately
from DRG payments. Recent federal legislation reduced capital cost reimbursement
under the Medicare capital cost pass-through system. The legislation requires
that the aggregate amount of reimbursements in fiscal years 1992 through 1995 be
reduced by approximately 10% per year. Such reductions have had an adverse
impact on reimbursements to hospitals for the capital cost of equipment such as
the Oracle Imaging System. Moreover, EndoSonics is unable to predict what
additional legislation or regulation, if any, relating to the health care
industry or third-party coverage and reimbursement may be enacted in the future,
or what effect such legislation or regulation would have on EndoSonics.
 
     Competition.  Competition in the market for devices used in the diagnosis
and treatment of cardiovascular and peripheral vascular disease is intense, and
is expected to increase. The interventional cardiology market is characterized
by rapid technological innovation and change, and EndoSonics' products could be
rendered obsolete as a result of future innovations. EndoSonics' digital,
all-electronic IVUS imaging catheters compete with mechanical ultrasound devices
manufactured by CVIS and Hewlett-Packard. Both CVIS and Hewlett-Packard are
significantly larger than EndoSonics, have significantly greater financial,
sales and marketing and technical resources available and have significantly
larger installed bases of imaging systems. These competitors have also developed
IVUS imaging products with high quality images and EndoSonics believes that its
competitive position is dependent upon its ability to establish its reputation
as a producer of high quality IVUS imaging products. There can be no assurance
that these companies are not currently developing, or will not attempt to
develop, combination balloon angioplasty/IVUS imaging catheters that would
compete with EndoSonics' combination balloon angioplasty/IVUS imaging products.
Moreover, companies currently engaged in the manufacture and marketing of
non-imaging angioplasty catheters could attempt to expand their product lines to
include combination balloon angioplasty/IVUS imaging products.
 
     EndoSonics' combination balloon angioplasty/IVUS imaging catheters compete
or will compete with therapeutic catheters marketed by a number of manufacturers
including Advanced Cardiovascular Systems, Inc., a subsidiary of Guidant
Corporation ("ACS"), SCIMED Life Systems, Inc., a subsidiary of Boston
Scientific Corporation ("SCIMED"), Cordis, Medtronic, Inc. ("Medtronic"), and
Schneider USA, a subsidiary of Pfizer, Inc. ("Schneider"). Such companies have
substantial resources, established market positions, and significantly larger
sales and marketing organizations. In addition,
 
                                       21
<PAGE>   33
 
EndoSonics faces competition from manufacturers of atherectomy devices, vascular
stents and pharmaceutical products intended to treat cardiovascular disease.
 
     Reliance on Patents and Proprietary Technology; Risk of Patent
Infringement.  EndoSonics holds six issued United States patents and has other
United States and several foreign patent applications pending covering various
aspects of its IVUS imaging technology. No assurance can be given, however, that
EndoSonics' patent applications will issue as patents or that any issued patents
will provide competitive advantages for EndoSonics' products or will not be
successfully challenged or circumvented by its competitors. Although EndoSonics
attempts to ensure that its products do not infringe other party's patents and
proprietary rights, there can be no assurance that its products do not infringe
such patents or rights. The interventional cardiovascular market has been
characterized by substantial litigation regarding patent and other intellectual
property rights. In the event that any relevant claims of third-party patents
are upheld as valid and enforceable, EndoSonics could be prevented from
practicing the subject matter claimed in such patents, or would be required to
obtain licenses from the owners of any such patents or redesign its products or
processes to avoid infringement. There can be no assurance that such licenses
would be available or, if available, would be so on terms acceptable to
EndoSonics or that EndoSonics would be successful in any attempt to redesign its
products or processes to avoid infringement. EndoSonics also relies on trade
secrets and proprietary technology and enters into confidentiality and
non-disclosure agreements with its employees and consultants. There can be no
assurance that the confidentiality of such trade secrets or proprietary
information will be maintained by employees, consultants, advisors or others, or
that EndoSonics' trade secrets or proprietary technology will not otherwise
become known or be independently developed by competitors in such a manner that
EndoSonics has no practical recourse. Litigation may be necessary to defend
against claims of infringement or invalidity, to enforce patents issued to
EndoSonics or to protect trade secrets and could result in substantial cost to,
and diversion of effort by, EndoSonics.
 
     Government Regulation.  The manufacturing and marketing of EndoSonics'
products are subject to extensive and rigorous government regulation in the
United States and in other countries. EndoSonics believes that its success will
be significantly dependent upon commercial sales of improved versions of its
imaging systems and catheter products. EndoSonics will not be able to market
these new products in the United States unless and until it obtains approval
from the FDA.
 
     If a medical device manufacturer can establish that a newly developed
device is "substantially equivalent" to a device that was legally marketed prior
to May 1976, or to a device that the FDA has found to be substantially
equivalent to a legally marketed pre-1976 device, the manufacturer may seek
clearance from the FDA to market the device by filing a premarket notification
with the FDA under Section 510(k) of the Federal Food, Drug, and Cosmetic Act
("510(k)"). There can be no assurance that 510(k) clearance for any future
product or modification of an existing product will be granted or that the
process will not be unduly lengthy. All of the 510(k) clearances received for
EndoSonics' catheters were based on substantial equivalence to legally marketed
pre-1976 devices. Review of the substantially equivalent pre-1976 devices on
which the 510(k) clearances for EndoSonics' catheters were based and any
resulting restrictions on EndoSonics or requirements imposed to present
additional data could have a material adverse effect on EndoSonics' business,
financial condition and results of operations.
 
     If substantial equivalence cannot be established, or if the FDA determines
that the device or the particular application for the device requires a more
rigorous review, the FDA will require that the manufacturer submit a PMA
application that must be reviewed and approved by the FDA prior to sales and
marketing of the device in the United States. The PMA process is significantly
more complex, expensive and time consuming than the 510(k) clearance process and
frequently requires the submission of clinical data. It is expected that certain
of EndoSonics' combination angioplasty/IVUS imaging products under development
will be subject to this PMA process. Failure to comply with applicable
regulatory requirements can, among other consequences, result in fines,
injunctions, civil penalties, suspensions or loss of regulatory approvals,
product recalls, seizure of products, operating restrictions and criminal
prosecution. In addition, governmental regulations may be established that
 
                                       22
<PAGE>   34
 
could prevent or delay regulatory approval of EndoSonics' products. Delays in
receipt of approvals, failure to receive approvals or the loss of previously
received approvals would have a material adverse effect on EndoSonics' business,
financial condition and results of operations.
 
     EndoSonics is also required to register as a medical device manufacturer
with the FDA and certain state agencies, such as the Food and Drug Branch of the
California Department of Health Services ("CDHS"). As such, EndoSonics is
inspected on a routine basis by both the FDA and the CDHS for compliance with
the GMP regulations. These regulations require that EndoSonics manufacture its
products and maintain related documentation in a prescribed manner with respect
to manufacturing, testing and control activities. Further, EndoSonics is
required to comply with various FDA requirements for labeling. The Medical
Device Reporting regulation requires that EndoSonics provide information to the
FDA on deaths or serious injuries alleged to have been associated with the use
of its devices, as well as product malfunctions that would likely cause or
contribute to death or serious injury if the malfunction were to recur. In
addition, the FDA prohibits an approved device from being marketed for
unapproved applications. Specifically, EndoSonics' FOCAL balloon catheters are
approved in certain European countries. EndoSonics believes that these catheters
are being used in those countries principally for deployment of coronary stents
and balloon angioplasty. In October 1995, Endosonics received FDA approval to
market CVD's line of FACT catheters, which utilize the FOCAL technology, for
coronary balloon angioplasty. Without specific FDA approval for use in stent
deployment, these catheters may not be marketed by EndoSonics in the United
States for such use. If the FDA believes that a company is not in compliance
with applicable laws and regulations, it can institute proceedings to detain or
seize products, issue a recall, prohibit marketing and sales of the company's
products and assess civil and criminal penalties against the company, its
officers or its employees.
 
     EndoSonics is also subject to other federal, state and local laws,
regulations and recommendations relating to safe working conditions, laboratory
and manufacturing practices. The extent of government regulation that might
result from any future legislation or administrative action cannot be accurately
predicted. Failure to comply with regulatory requirements could have a material
adverse effect on EndoSonics' business, financial condition and results of
operations.
 
     International sales of EndoSonics' products are subject to the regulatory
agency product registration requirements of each country. The regulatory review
process varies from country to country and may in some cases require the
submission of clinical data. EndoSonics typically relies on its distributors in
such foreign countries to obtain the requisite regulatory approvals. There can
be no assurance, however, that such approvals will be obtained on a timely basis
or at all.
 
     EndoSonics is in the process of implementing policies and procedures which
are intended to allow it to receive ISO 9001 qualification of its processes. The
ISO 9000 series of standards for quality operations has been developed to ensure
that companies know the standards of quality to which they must adhere to
receive certification. The European Union has promulgated rules which require
that medical products receive by mid-1998 the right to affix the CE mark, an
international symbol of adherence to quality assurance standards and compliance
with applicable European medical device directives. ISO 9001 certification is
one of the CE mark certification requirements. Failure to receive the right to
affix the CE mark will prohibit EndoSonics from selling its products in member
countries of the European Union. In Europe, EndoSonics has obtained ISO 9002 as
of January 1997. There can be no assurance that EndoSonics will be successful in
meeting certification requirements.
 
     Potential Product Liability; Limited Insurance.  EndoSonics faces the risk
of financial exposure to product liability claims. EndoSonics' products are
often used in situations in which 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.
EndoSonics maintains product liability insurance with coverage limits of $1.0
million per occurrence and $5.0 million per year in the aggregate. There can be
no assurance that EndoSonics' product liability insurance is adequate or that
such insurance coverage will remain available at acceptable costs. There can be
no assurance that EndoSonics will not incur significant product liability claims
in the future. A successful claim brought
 
                                       23
<PAGE>   35
 
against EndoSonics in excess of its insurance coverage could have a material
adverse effect on EndoSonics' business, financial condition and results of
operations. Additionally, adverse product liability actions could negatively
affect the reputation and sales of EndoSonics' products as well as EndoSonics'
ability to obtain and maintain regulatory approval for its products.
 
RISK FACTORS THAT MAY AFFECT FUTURE RESULTS OF CARDIOMETRICS
 
     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.
 
  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.
 
  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 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.
 
  History of Losses; Likelihood of Additional Losses; Limited Operating History
 
     Cardiometrics has incurred net losses since its incorporation in October
1985. As of March 31, 1997, Cardiometrics' accumulated deficit was $35.5
million, $25.7 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.
 
                                       24
<PAGE>   36
 
  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, the inability of such
vendor to supply such component would have an adverse effect on Cardiometrics'
business, financial condition and results of operations.
 
  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.
 
  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
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.
 
  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
 
                                       25
<PAGE>   37
 
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 market successfully the
WaveWire/WaveMap system or other new or enhanced products would have a material
adverse effect on the business, operating results and financial condition of
Cardiometrics.
 
  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.
 
  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, 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.
 
  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
 
                                       26
<PAGE>   38
 
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.
 
  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 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.
 
                                       27
<PAGE>   39
 
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.
 
  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
 
                                       28
<PAGE>   40
 
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 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 WaveWire XT, and subsequently received a letter from
the FDA dated March 21, 1997 requesting additional information to be submitted
to the FDA to support the determination of whether the WaveWire/WaveMap system
is substantially equivalent to a legally marketed predicate device with regard
to its safety and effectiveness. On April 9, 1997, Cardiometrics requested a 90
day extension to submit the requested data. The FDA, on April 15, 1997, granted
the extension until July 21, 1997. Cardiometrics submitted the requested data on
June 9, 1997. Cardiometrics 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 vasodilation (the point when the medial (middle) layer of a blood vessel
is completely relaxed, allowing a natural expansion of the inner lumen to allow
for 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.
 
                                       29
<PAGE>   41
 
     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 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.
 
  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.
 
  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
 
                                       30
<PAGE>   42
 
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.
 
  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.
 
RISK FACTORS THAT MAY AFFECT FUTURE RESULTS OF CVD
 
     CVD operates in a highly competitive environment that involves a number of
risks, some of which are beyond CVD's control. The following discussion
highlights some of these risks.
 
     History of Operating Losses; Anticipated Future Losses; Future Capital
Requirements.  CVD operates in a highly competitive environment that involves a
number of risks, some of which are beyond CVD's control. The following
discussion highlights some of these risks. CVD was founded in 1992 and has
experienced annual operating losses since its inception. Its net loss was $1.0
million, $2.9 million and $4.6 million in 1994, 1995 and 1996, respectively.
CVD's accumulated deficit at March 31, 1997 was approximately $11.6 million. CVD
expects to continue to incur operating losses through at least 1997 and there
can be no assurance that CVD will ever be able to achieve or sustain
profitability in the future. CVD expects to incur substantially increased costs
related to, among other things, clinical testing, product development,
manufacturing scale-up and sales and marketing activities. CVD anticipates that
its existing capital resources will be sufficient to fund its operations through
1997. CVD's future capital requirements will depend on many factors, including
its research and development programs, the scope and results of clinical trials,
the time and costs involved in obtaining regulatory approvals, the costs
involved in obtaining and enforcing patents or any litigation by third parties
regarding intellectual property, the status of competitive products, the
establishment and scale-up of manufacturing capacity, the establishment of sales
and marketing capabilities, the establishment of collaborative relationships
with other parties and costs related to the acquisition of new technologies and
product development. CVD may require additional funds to finance these
activities and for working capital requirements. CVD may seek such funds through
financings, including private or public equity or debt offerings and
collaborative arrangements with corporate partners. There can be no assurance
that funds will be raised on favorable terms, if at all. If adequate funds are
not available, CVD may be required to delay, scale back or eliminate one or more
of its development programs or obtain funds through arrangements with
collaborative partners or others that may require CVD to relinquish rights to
certain technologies, product candidates or products that CVD would not
otherwise relinquish.
 
     Dependence Upon New Products; Rapid Technological Change; Risk of
Obsolescence.  The medical device industry generally, and the interventional
catheter market in particular, are characterized by rapid technological change,
changing customer needs, and frequent new product introductions. As a result,
the useful lives of both the technology and products for the treatment of
cardiovascular and peripheral vascular diseases are limited, in some instances
to as little as twelve months. CVD's future success will depend upon its ability
to develop, manufacture and introduce new products that address the needs of its
customers. There can be no assurance that CVD will be successful in developing
and marketing new products that achieve market acceptance or that CVD will not
experience difficulties that could delay or prevent the successful development,
introduction and marketing of new products. In addition, there can
 
                                       31
<PAGE>   43
 
be no assurance that CVD's existing products will not be rendered obsolete as a
result of technological developments or that the products that CVD has under
development will not be rendered obsolete prior to the introduction of such
products.
 
     Limited Sales to Date; Uncertainty of Market Acceptance.  CVD's catheters
are used in conjunction with angioplasty and other intravascular procedures such
as vascular stenting and drug delivery. Although CVD has received regulatory
clearance for a total of fifty-two products, only twenty-nine of such products
have been marketed. Of those products which have been marketed, many have been
marketed only in limited quantities or in certain markets, or are allowed to be
marketed only in certain countries. In addition, while interventional catheters
are widely used technologies, CVD's catheter designs are relatively new. The
commercial success of CVD's products will depend upon their acceptance by the
medical community as useful, cost-effective components of interventional
cardiovascular and peripheral vascular procedures, including the acceptance by
the medical community of stents and the availability and acceptance of
therapeutic drugs for use in interventional procedures. CVD currently relies
upon relationships with certain prominent doctors and researchers in the medical
community to promote the uses and acceptance of its approved products. There can
be no assurance that CVD will be able to maintain such relationships or
establish additional relationships in the future. The erosion or loss of any
such relationship could detrimentally affect the market acceptance of CVD's
products. Failure of CVD's products to achieve such market acceptance would have
a material adverse effect on CVD's business, financial condition and results of
operations.
 
     Fluctuations in Quarterly Operating Results.  CVD's results of operations
have varied significantly from quarter to quarter. CVD has experienced an
operating loss for each of the last five years. Quarterly operating results will
depend upon several factors, including the timing and amount of expenses
associated with expanding CVD's operations, the conduct of clinical trials and
the timing of regulatory approvals, new product introductions both in the United
States and internationally, the mix between pilot production of new products and
full-scale manufacturing of existing products, the mix between domestic and
export sales, variations in foreign exchange rates, changes in third-party
payors' reimbursement policies and healthcare reform. CVD does not operate with
a significant backlog of customer orders, and therefore revenues in any quarter
are significantly dependent on orders received within that quarter. In addition,
CVD cannot predict ordering rates by distributors, some of whom place infrequent
stocking orders. CVD's expenses are relatively fixed and difficult to adjust in
response to fluctuating revenues. As a result of these and other factors, CVD
expects to continue to experience significant fluctuations in quarterly
operating results, and there can be no assurance that CVD will be able to
achieve or maintain profitability in the future.
 
     Reliance on Patents and Proprietary Technology; Risk of Patent
Infringement.  While CVD owns certain issued and allowed U.S. patents and has
additional U.S. and foreign patent applications pending, there can be no
assurance that CVD's patent applications will issue as patents or that any
issued patents will provide competitive advantages for CVD's products or will
not be successfully challenged or circumvented by its competitors. The
interventional cardiovascular and peripheral vascular markets in general and the
market for balloon angioplasty catheters (including the type of catheters
offered by CVD) in particular have been characterized by substantial litigation
regarding patent and other intellectual property rights. There can be no
assurance that CVD's products do not infringe such patents or rights. During
1996, CVD received a notice of potential trademark infringement regarding CVD's
use of the term "focal" in connection with CVD's balloon angioplasty technology
and entered into an agreement which prohibits CVD from using this term. CVD has
since ceased any use thereof. In the event that any parties assert claims
against CVD for patent infringement and such patents are upheld as valid and
enforceable, CVD could be prevented from utilizing the subject matter claimed in
such patents, or would be required to obtain licenses from the owners of any
such patents or redesign its products or processes to avoid infringement. There
can be no assurance that such licenses would be available or, if available,
would be so on terms acceptable to CVD or that CVD would be successful in any
attempt to redesign its products or processes to avoid infringement. In
addition, foreign intellectual property laws may not provide protection
commensurate with that
 
                                       32
<PAGE>   44
 
provided by U.S. intellectual property laws, and there can be no assurance that
foreign intellectual property laws will adequately protect CVD's intellectual
property rights abroad. CVD also relies on trade secrets and proprietary
technology and enters into confidentiality and non-disclosure agreements with
its employees, consultants and advisors. There can be no assurance that the
confidentiality of such trade secrets or proprietary information will be
maintained by employees, consultants, advisors or others, or that CVD's trade
secrets or proprietary technology will not otherwise become known or be
independently developed by competitors in such a manner that CVD has no
practical recourse. Litigation may be necessary to defend against claims of
infringement or invalidity, to enforce patents issued to CVD or to protect trade
secrets, and there can be no assurance that any such litigation would be
successful. Any litigation could result in substantial costs to, and diversion
of resources by, CVD and its officers, which could have a material adverse
effect on the Company's business, financial condition and results of operations.
 
     Significant Competition.  Competition in the market for devices used in the
treatment of cardiovascular and peripheral vascular disease is intense, and is
expected to increase. The interventional cardiology market is characterized by
rapid technological innovation and change, and CVD's products could be rendered
obsolete as a result of future innovations. CVD's catheters and other products
under development compete or will compete with products marketed by a number of
manufacturers, including ACS, SCIMED, Johnson & Johnson Interventional Systems
("JJIS") and Cordis, Medtronic and Schneider. Such companies have significantly
greater financial, management and other resources, established market positions,
and significantly larger sales and marketing organizations than does CVD. CVD
also faces competition from manufacturers of other catheter-based devices,
vascular stents and pharmaceutical products intended to treat vascular disease.
In addition, CVD believes that many of the customers and potential customers of
CVD's products prefer to purchase catheter products from a single source.
Accordingly, many of CVD's competitors, because of their size and range of
product offerings, have a competitive advantage over CVD. There can be no
assurance that CVD's competitors will not succeed in developing or marketing
technologies or products that are more clinically effective or cost effective
than any that are being marketed or developed by CVD, or that such competitors
will not succeed in obtaining regulatory approval for introducing or
commercializing any such products prior to CVD.
 
     Limited Manufacturing Experience.  CVD's success will depend in part on its
ability to manufacture its products in compliance with ISO 9001, the FDA's GMP
regulations, CDHS licensing and other regulatory requirements, in sufficient
quantities and on a timely basis, while maintaining product quality and
acceptable manufacturing costs. CVD began manufacturing certain of its products
at its facilities in July 1995. CVD also introduced a significant number of new
products in 1996. Accordingly, CVD has very limited experience in manufacturing
its products. In addition, on July 15, 1996, CVD entered into co-distribution
agreements with Medtronic which granted Medtronic certain non-exclusive rights
to distribute CVD's FACT, CAT and ARC catheters. Under the terms of these
agreements, if CVD is unable to meet its delivery obligations with respect to
the purchased catheters, up to 60% of CVD's manufacturing capacity will be
devoted to manufacturing such catheters for Medtronic. CVD has undergone and
expects to continue to undergo regular GMP inspections in connection with the
manufacture of its products at CVD's facilities. CVD's success will depend,
among other things, on its ability to efficiently manage the simultaneous
manufacture of different products and to integrate the manufacture of new
products with existing products. There can be no assurance that CVD will not
encounter difficulties in scaling up production of new products, including
problems involving production yields, quality control and assurance, component
supply and shortages of qualified personnel. CVD's failure to successfully
commence the manufacturing of these new products, or to increase production
volumes of new or existing products in a timely manner, would materially
adversely affect CVD's business, financial condition and results of operations.
Failure to increase production volumes in a timely or cost-effective manner or
to achieve or maintain compliance with ISO 9001, GMP regulations, CDHS licensing
or other regulatory requirements could have a material adverse effect on CVD's
business, financial condition and results of operations.
 
                                       33
<PAGE>   45
 
     CVD purchases many standard and custom built components from independent
suppliers and subcontracts certain manufacturing processes from independent
vendors. Most of these components and processes are available from more than one
vendor. However, certain manufacturing processes are currently performed by
single vendors. An interruption of performance by any of these vendors could
have a material adverse effect on CVD's ability to manufacture its products
until a new source of supply was qualified and, as a result, could have an
adverse effect on CVD's business, financial condition and results of operations.
 
     Potential Inability to Manage Growth.  Prior to June 1996, CVD relied on
EndoSonics to perform certain activities on its behalf, including manufacturing,
financial, regulatory and administrative functions. Since July 1995, CVD has
conducted its manufacturing operations at its facilities in Irvine and also
currently performs the financial, regulatory and administrative functions
previously performed by EndoSonics. Accordingly, CVD has experienced a period of
significant expansion of its operations that has placed a significant strain
upon its management systems and resources. CVD has recently implemented a number
of new financial and management controls, reporting systems and procedures. In
addition, CVD has recently hired a significant number of employees and plans to
further increase its total head count. CVD also plans to expand the geographic
scope of its customer base and operations. This expansion has resulted and will
continue to result in substantial demands on CVD's management resources. CVD's
ability to manage future expansion of its operations will require CVD to
continue to improve its financial and management controls, reporting systems and
procedures on a timely basis and to expand, train and manage its employee work
force. There can be no assurance that CVD will be able to do so successfully.
The failure to do so would have a material adverse effect on CVD's business,
financial condition and results of operations.
 
     Government Regulation.  The manufacturing and marketing of CVD's products
are subject to extensive and rigorous government regulation in the United States
and in other countries. CVD believes that its success will be significantly
dependent upon commercial sales of improved versions of its catheter products.
CVD will not be able to market these new products in the United States unless
and until CVD obtains approval or clearance from the FDA. Foreign and domestic
regulatory approvals, if granted, may include significant limitations on the
indicated uses for which a product may be marketed.
 
     If a medical device manufacturer can establish that a newly developed
device is "substantially equivalent" to a legally marketed Class I or Class II
device, or to a Class III device that the FDA has not called for a premarket
approval ("PMA"), the manufacturer may seek clearance from the FDA to market the
device by filing a premarket notification with the FDA under Section 510(k) of
the Federal Food, Drug, and Cosmetic Act ("510(k)"). All of the 510(k)
clearances received for CVD's catheters were based on substantial equivalence to
legally marketed devices. There can be no assurance that 510(k) clearance for
any future product or significant modification of an existing product will be
granted or that the process will not be unduly lengthy. In addition, if the FDA
has concerns about the safety or effectiveness of any of CVD's products, it
could act to withdraw approval or clearances of those products or request that
CVD present additional data. Any such actions would have a material adverse
effect on CVD's business, financial condition and results of operations.
 
     If substantial equivalence cannot be established, or if the FDA determines
that the device or the particular application for the device requires a more
rigorous review to assure safety and effectiveness, the FDA will require that
the manufacturer submit a PMA application that must be reviewed and approved by
the FDA prior to sales and marketing of the device in the United States. The PMA
process is significantly more complex, expensive and time consuming than the
510(k) clearance process and always requires the submission of clinical data. It
is expected that certain of CVD's products under development will be subject to
this PMA process. CVD currently has a non-exclusive, royalty-free right to
submit PMA supplement applications utilizing an EndoSonics PMA as a reference
and to manufacture and distribute CVD products as a supplement to the EndoSonics
PMA. This agreement may be terminated in the event of breach upon 60 days notice
by the non-breaching party, subject to the breaching party's right to cure. In
the event of termination, CVD would be prohibited from submitting
 
                                       34
<PAGE>   46
 
new PMA supplements referencing the EndoSonics PMA and would be required to seek
independent FDA approval for any such products, which would have a material
adverse effect on CVD's business, financial condition and results of operations.
 
     CVD is also required to register as a medical device manufacturer with the
FDA and maintain a license with certain state agencies, such as the CDHS. As
such, CVD is inspected on a routine basis by both the FDA and the CDHS for
compliance with GMP regulations. These regulations require that CVD manufacture
its products and maintain related documentation in a prescribed manner with
respect to manufacturing, testing and control activities. CVD has also undergone
and expects to continue to undergo regular GMP inspections in connection with
the manufacture of its products at
CVD's facilities. Further, CVD is required to comply with various FDA
requirements for labeling. The Medical Device Reporting laws and regulations
require that CVD provide information to the FDA on deaths or serious injuries
alleged to have been associated with the use of its devices, as well as product
malfunctions that would likely cause or contribute to death or serious injury if
the malfunction were to recur. In addition, the FDA prohibits an approved device
from being marketed for unapproved applications. CVD has received FDA approval
to market the FACT and ARC catheters, which utilize the Focus technology, for
coronary balloon angioplasty. These catheters are marketed outside the United
States for use in stent deployment. However, without specific FDA approval for
stent deployment, these catheters may not be marketed by CVD in the United
States for such use.
 
     Failure to comply with applicable regulatory requirements can, among other
consequences, result in fines, injunctions, civil penalties, suspensions or loss
of regulatory approvals, product recalls, seizure of products, operating
restrictions and criminal prosecution. In addition, government regulations may
be established in the future that could prevent or delay regulatory clearance or
approval of CVD's products. Delays in receipt of clearances or approvals,
failure to receive clearances or approvals or the loss of previously received
clearances or approvals would have a material adverse effect on CVD's business,
financial condition and results of operations.
 
     CVD is also subject to other federal, state and local laws, regulations and
recommendations relating to safe working conditions, laboratory and
manufacturing practices. The extent of government regulation that might result
from any future legislation or administrative action cannot be accurately
predicted. Failure to comply with regulatory requirements could have a material
adverse effect on CVD's business, financial condition and results of operations.
 
     International sales of CVD's products are subject to the registration
requirements of each country. The regulatory review process varies from country
to country and may in some cases require the submission of clinical data. CVD
typically relies on its distributors in such foreign countries to obtain the
requisite regulatory approvals. There can be no assurance, however, that such
approvals will be obtained on a timely basis or at all. In addition, the FDA
must approve the export to certain countries of devices that require a PMA but
are not yet approved domestically. The European Union has promulgated rules
which require that medical products receive by mid-1998 the right to affix the
CE mark, an international symbol of adherence to quality assurance standards and
compliance with applicable European medical device directives. Failure to
receive the right to affix the CE mark will prevent CVD from selling its
products in member countries of the European Union which would have a material
adverse effect on CVD's business, financial condition and results of operations.
 
     Limited Marketing and Sales Resources; Dependence Upon Strategic
Relationships.  CVD intends to rely primarily on certain strategic
relationships, medical device distributors and its direct sales organization to
distribute its products. CVD's ability to distribute its products successfully
depends in part on the marketing capabilities of its strategic partners. In
recent years there has been significant consolidation among medical device
suppliers as the major suppliers have attempted to broaden their product lines
in order to respond to cost pressures from health care providers. This
consolidation has made it increasingly difficult for smaller suppliers, such as
CVD, to effectively distribute their products without a relationship with one or
more of the major suppliers. CVD is currently marketing certain of its products
through licensing agreements with SCIMED and ACS and through co-distribution
agree-
 
                                       35

ments with Medtronic. In addition, Fukuda Denshi Company, Ltd. ("Fukuda") is
currently CVD's exclusive distributor in Japan for certain of CVD's products.
Fukuda is also responsible for obtaining regulatory approval for CVD's products
in Japan. CVD recently informed Fukuda of its decision to terminate the existing
Fukuda agreement and does not expect that any obligations will arise as a result
of such termination. CVD expects that Fukuda will continue to distribute its
products at least through 1997. CVD is currently negotiating with several
distributors, including Fukuda, regarding a new distribution agreement for the
Japanese market. CVD's revenue from its distributor relationships is dependent
upon the efforts made by such parties and there can be no assurance that such
efforts will be successful. There can be no assurance that CVD will be able to
maintain or expand its relationships with its strategic partners or to replace
its strategic partners in the event any such relationship were terminated. In
the event of such a termination, CVD's ability to distribute its products would
be materially adversely affected, which would have a material adverse effect on
CVD's business, financial condition and results of operations.
 
     CVD currently has a limited marketing and sales staff. CVD intends to
expand its direct sales force to market CVD's products expansion. However, there
can be no assurance that CVD will successfully expand its direct sales and
marketing organization, or that if expanded, such organization will be able to
effectively distribute CVD's products. If CVD is unable to achieve distribution
of its products through its direct sales organization, CVD's business, financial
condition and results of operations would be materially adversely affected.
 
     CVD also has product development relationships with SCIMED and ACS. SCIMED
currently funds certain research and development efforts undertaken by CVD in
the area of combined drug delivery and coronary angioplasty. ACS conducts
development work on CVD's perfusion technology. If CVD is unable to maintain its
relationships with these or future strategic partners its product development
efforts could be materially adversely affected, which would materially adversely
affect CVD's business, financial condition and results of operations.
 
     Dependence Upon International Sales.  CVD derives, and expects to continue
to derive, a significant portion of its revenue from international sales. In
1994, 1995 and 1996, CVD's international sales were $1.0 million, $2.1 million
and $3.5 million, respectively, or 83%, 59% and 42%, respectively, of product
sales. CVD expects to continue to derive significant revenue from international
sales and therefore a significant portion of its revenues will continue to be
subject to the risks associated with international sales, including economic or
political instability, shipping delays, changes in applicable regulatory
policies, inadequate protection of intellectual property, fluctuations in
foreign currency exchange rates and various trade restrictions, all of which
could have a significant impact on CVD's ability to deliver products on a
competitive and timely basis. Future imposition of, or significant increases in
the level of, customs duties, import quotas or other trade restrictions, could
have an adverse effect on CVD's business, financial condition and results of
operations. In foreign countries, CVD's products are subject to governmental
review and certification. The regulation of medical devices, particularly in the
European Union, continues to expand and there can be no assurance that new laws
or regulations will not have an adverse effect on CVD's business, financial
condition and results of operations.
 
     Limitations on Third-Party Reimbursement.  In the United States, CVD's
products are purchased primarily by medical institutions, which then bill
various third-party payors, such as Medicare, Medicaid, and other government
programs and private insurance plans, for the health care services provided to
patients. Government agencies, private insurers and other payors determine
whether to provide coverage for a particular procedure and reimburse hospitals
for medical treatment at a fixed rate based on the DRG established by the U.S.
HCFA. The fixed rate of reimbursement is based on the procedure performed, and
is unrelated to the specific devices used in that procedure. If a procedure is
not covered by a DRG, payors may deny reimbursement. In addition, some payors
may deny reimbursement if they determine that the device used in a treatment was
unnecessary, inappropriate or not cost-effective, experimental or used for a
non-approved indication. Reimbursement of interventional procedures utilizing
CVD's products is currently covered under a DRG. There can be no assurance that
reimbursement for such procedures will continue to be available, or that future
 
                                       36
<PAGE>   48
 
reimbursement policies of payors will not adversely affect CVD's ability to sell
its products on a profitable basis. In addition, reimbursement may be denied if
the product use is not in accordance with approved FDA labeling. Failure by
hospitals and other users of CVD's products to obtain reimbursement from
third-party payors, or changes in government and private third-party payors'
policies toward reimbursement for procedures employing CVD's products, would
have a material adverse effect on CVD's business, financial condition and
results of operations.
 
     Control by Existing Stockholder; Limitations on Pooling-of-Interests
Accounting in Merger Transactions. Immediately prior to the distribution of the
shares of CVD Common Stock by EndoSonics pursuant to the CVD Prospectus,
EndoSonics owned approximately 44% of CVD's outstanding Common Stock. After such
distribution, EndoSonics is expected to own approximately 28.7% of CVD's
outstanding Common Stock. As a result, EndoSonics is able to elect at least one
member to CVD's five person board of directors and has the ability to influence
CVD and influence its affairs and the conduct of its business. Such
concentration of ownership may have the effect of delaying, deferring or
preventing a change in control of CVD. In accordance with applicable accounting
standards, CVD is prohibited from accounting for a merger transaction, of or by
CVD, as a pooling-of-interests for a period of two years following June 25,
1996, the date on which EndoSonics ceased to control 50% of the outstanding
voting Common Stock of CVD. As a result, any business combination consummated
prior to the expiration of such period would have to be accounted for using the
purchase method. Under the purchase method, the excess of the purchase price
over the net book value of the assets acquired would be amortized to expense,
which could result in a significant negative impact on the acquiror's results of
operations and, therefore, reduce the attractiveness of, or the price paid in, a
particular acquisition transaction.
 
     On January 27, 1997, EndoSonics announced that the EndoSonics Board of
Directors had approved a dividend distribution of one CVD share for every 25
EndoSonics shares. The distribution is expected to take place in the second half
of 1997 to EndoSonics stockholders then of record. The exact record date and
date of distribution have not yet been determined.
 
     Dependence Upon Key Personnel.  CVD depends to a significant extent upon
key management and technical personnel. CVD's growth and future success will
depend in large part upon its ability to hire, motivate and retain highly
qualified personnel. Competition for such personnel is intense and there can be
no assurance that CVD will be successful in hiring, motivating or retaining such
qualified personnel. The loss of key personnel or the inability to hire or
retain qualified personnel could have a material adverse effect on CVD's
business, financial condition and results of operations.
 
     Potential Product Liability; Limited Insurance.  CVD faces the risk of
financial exposure to product liability claims. CVD's products are often used in
situations in which 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. CVD is currently
covered under a product liability insurance policy with coverage limits of $2.0
million per occurrence and $2.0 million per year in the aggregate. There can be
no assurance that CVD's product liability insurance is adequate or that such
insurance coverage will remain available at acceptable costs. There can be no
assurance that CVD will not incur significant product liability claims in the
future. A successful claim brought against CVD in excess of its insurance
coverage could have a material adverse effect on CVD's business, financial
condition and results of operations. Additionally, adverse product liability
actions could negatively affect the reputation and sales of CVD's products and
CVD's ability to obtain and maintain regulatory approval for its products and
substantially divert the time and effort of management away from CVD's
operations.
 
     Shares Eligible for Future Sale; Potential Adverse Effect on Market
Price.  Sales of Common Stock in the public market during and after this
offering could adversely affect the market price of the Common Stock. As of
April 15, 1997, CVD had 9,103,459 shares outstanding. Including all of the
shares of CVD Common Stock registered for sale under the CVD Registration
Statement, 5,610,054 of CVD's outstanding shares are freely tradable without
restriction. Approximately 2,531,768 additional shares are eligible for sale,
including 1,809,768 shares held by EndoSonics, not registered for sale
hereunder,
 
                                       37
<PAGE>   49
 
and 646,000 shares held by SCIMED. Sales of any such shares in the public market
could adversely affect the market price of the Common Stock. CVD has also
registered 1,200,000 shares of Common Stock reserved for issuance under CVD's
1996 Stock Option/Stock Issuance Plan and 200,000 shares under CVD's Employee
Stock Purchase Plan. As of April 15, 1997, there were outstanding options under
CVD's stock option plans to acquire approximately 1,188,000 shares. SCIMED is
entitled to certain demand piggyback registration rights with respect to its
shares. If SCIMED, by exercising its demand registration rights, causes a large
number of shares to be registered and sold in the public market, such sales
could have an adverse effect on the market price for the Common Stock. If CVD
were required to include in a CVD-initiated registration shares held by SCIMED
pursuant to the exercise of its piggyback registration rights, such sales may
have an adverse effect on CVD's ability to raise needed capital.
 
     Effect of Certain Charter Provisions; Anti-takeover Effects of Certificate
of Incorporation, Bylaws and Delaware Law.  CVD's Board of Directors has the
authority to issue up to 5,000,000 shares of Preferred Stock and to determine
the price, rights, preferences, privileges and restrictions, including voting
rights, of those shares without any further vote or action by the stockholders.
The rights of the holders of Common Stock will be subject to, and may be
adversely affected by, the rights of the holders of any Preferred Stock that may
be issued in the future. The issuance of Preferred Stock could have the effect
of making it more difficult for a third party to acquire a majority of the
outstanding voting stock of CVD. In addition, CVD is subject to the
anti-takeover provisions of Section 203 of the Delaware General Corporation Law,
which will prohibit CVD from engaging in a "business combination" with an
"interested stockholder" for a period of three years after the date of the
transaction in which the person became an interested stockholder, unless the
business combination is approved in a prescribed manner. The application of
Section 203 also could have the effect of delaying or preventing a change of
control of CVD. Further, certain provisions of CVD's Certificate of
Incorporation and Bylaws and of Delaware law could delay or make more difficult
a merger, tender offer or proxy contest involving CVD, which could adversely
affect the market price of CVD's Common Stock.
 
     Absence of Dividends.  CVD has never paid any cash dividends on the Common
Stock and does not anticipate paying any cash dividends on the Common Stock in
the foreseeable future.

                           THE CARDIOMETRICS MEETING
 
DATE, TIME AND PLACE OF THE CARDIOMETRICS MEETING
 
     The Cardiometrics Meeting will be held on July 23, 1997 at 10:00 a.m.,
local time, at Cardiometrics' facilities located at 645 Clyde Avenue, Mountain
View, California 94043.
 
MATTERS TO BE CONSIDERED AT THE CARDIOMETRICS MEETING
 
     At the Cardiometrics Meeting, stockholders of Cardiometrics will be asked
to consider and vote upon proposals (i) to approve and adopt the Reorganization
Agreement and to approve the consummation of the Merger and (ii) to transact
such other business as may properly come before the Cardiometrics Meeting or any
postponements or adjournments thereof.
 
BOARD RECOMMENDATION
 
     THE CARDIOMETRICS BOARD OF DIRECTORS HAS APPROVED THE REORGANIZATION
AGREEMENT AND THE MERGER AND BELIEVES THAT THE TERMS OF THE REORGANIZATION
AGREEMENT ARE FAIR TO, AND THAT THE MERGER IS IN THE BEST INTERESTS OF,
CARDIOMETRICS AND ITS STOCKHOLDERS AND THEREFORE RECOMMENDS THAT THE HOLDERS OF
CARDIOMETRICS COMMON STOCK VOTE FOR APPROVAL AND ADOPTION OF THE REORGANIZATION
AGREEMENT AND THE CONSUMMATION OF THE MERGER. In considering such
recommendation, Cardiometrics stockholders should be aware that certain
directors and officers of Cardiometrics have interests in the Merger that may
present them with potential conflicts of interest. See "The Merger and Related
Transactions -- The Agreement and Plan of Reorganization -- Indemnification and
Insurance" and "-- Interests of Certain Persons in the Merger."
 
RECORD DATE AND SHARES ENTITLED TO VOTE
 
     The Cardiometrics Board of Directors has fixed the close of business on May
30, 1997 as the record date for determining holders entitled to notice of and to
vote at the Cardiometrics Meeting (the "Record Date"). Only holders of record of
Cardiometrics Common Stock at the close of business on the Record Date are
entitled to notice of and to vote at the Cardiometrics Meeting. As of the close
of business on the Record Date, there were 6,982,173 shares of Cardiometrics
Common Stock outstanding and entitled to vote, held of record by 99 stockholders
(although Cardiometrics has been informed that there are approximately 1700
beneficial owners). A majority, or 3,491,087 of these shares, present in person
or represented by proxy, will constitute a quorum for the transaction of
business. Each Cardiometrics stockholder is entitled to one vote for each share
of Cardiometrics Common Stock held as of the Record Date.
 
VOTING OF PROXIES
 
     The Cardiometrics proxy accompanying this Proxy Statement/Prospectus is
solicited on behalf of the Cardiometrics Board for use at the Cardiometrics
Meeting. Stockholders are requested to complete, date and sign the accompanying
proxy and promptly return it in the accompanying envelope or otherwise mail it
to Cardiometrics. All properly executed proxies received by Cardiometrics prior
to the vote at the Cardiometrics Meeting, and that are not revoked, will be
voted at the Cardiometrics Meeting in accordance with the instructions indicated
on the proxies. The Cardiometrics Board does not presently intend to bring any
other business before the Cardiometrics Meeting and, so far as is known to the
Cardiometrics Board, no other matters are to be brought before the Cardiometrics
Meeting. As to any business that may properly come before the Cardiometrics
Meeting, however, it is intended that proxies, in the form enclosed, will be
voted in respect thereof in accordance with the judgment of the persons voting
such proxies. A Cardiometrics stockholder who has given a proxy (other than an
irrevocable proxy, such as those delivered pursuant to a Voting Agreement
referred to in "The Merger and Related Transactions -- Related
Agreements -- Voting Agreements") may revoke it at any time before it is
exercised at the Cardiometrics Meeting by (i) delivering to the Secretary of
Cardiometrics a written notice, bearing a date later than the date of the proxy,
stating that
 
                                       39
<PAGE>   51
 
the proxy is revoked, (ii) signing and so delivering a proxy relating to the
same shares and bearing a later date than the date of the previous proxy prior
to the vote at the Cardiometrics Meeting or (iii) attending the Cardiometrics
Meeting and voting in person (however, mere attendance at the meeting will not
in and of itself have the effect of revoking the proxy).
 
VOTE REQUIRED
 
     Approval of the Reorganization Agreement and the consummation of the Merger
by Cardiometrics' stockholders is required by the Delaware General Corporation
Law. Such approval requires the affirmative vote of the holders of a majority of
the shares of Cardiometrics Common Stock outstanding and entitled to vote.
Certain stockholders of Cardiometrics have entered into Voting Agreements and
have delivered irrevocable proxies obligating them to vote in favor of the
Reorganization Agreement and the consummation of the Merger. As of the Record
Date, such stockholders, constituting all executive officers and certain
directors of Cardiometrics and their affiliates, as a group beneficially owned
401,332 shares (exclusive of any shares issuable upon the exercise of options)
of Cardiometrics Common Stock (constituting approximately 5.7% of the shares of
Cardiometrics Common Stock then outstanding). As of the Record Date, EndoSonics
owned 300,000 shares of Cardiometrics Common Stock. See "The Merger and Related
Transactions -- Related Agreements -- Voting Agreements."
 
     Votes cast by proxy or in person at the Cardiometrics Meeting will be
tabulated by the Inspector of Elections appointed for the meeting. The Inspector
of Elections will also determine whether or not a quorum is present.
 
QUORUM; ABSTENTIONS AND BROKER NON-VOTES
 
     The required quorum for the transaction of business at the Cardiometrics
Meeting is a majority of the shares of Cardiometrics Common Stock issued and
outstanding on the Record Date. Abstentions and broker non-votes each will be
included in determining the number of shares present and voting at the meeting
for the purpose of determining the presence of a quorum. Because approval of the
Reorganization Agreement and the consummation of the Merger requires the
affirmative vote of a majority of the outstanding shares of Cardiometrics Common
Stock entitled to vote thereon, abstentions and broker non-votes will have the
same effect as votes against the Reorganization Agreement and the consummation
of the Merger. The actions proposed in this Proxy Statement/Prospectus are not
matters that can be voted on by brokers holding shares for beneficial owners
without the owners' specific instructions. Accordingly, all beneficial owners of
Cardiometrics Common Stock are urged to return the enclosed proxy card marked to
indicate their votes.
 
SOLICITATION OF PROXIES AND EXPENSES
 
     Cardiometrics will bear the cost of solicitation of proxies from its
stockholders estimated to be $5,000. In addition to solicitation by mail, the
directors, officers, employees and agents of Cardiometrics may solicit proxies
from stockholders by telephone, facsimile or in person. Following the original
mailing of the proxies and other soliciting materials, Cardiometrics will
request brokers, custodians, nominees and other record holders to forward copies
of the proxy and other soliciting materials to persons for whom they hold shares
of Cardiometrics Common Stock and to request authority for the exercise of
proxies. In such cases, Cardiometrics, upon the request of the record holders,
will reimburse such holders for their reasonable expenses.
 
     THE MATTERS TO BE CONSIDERED AT THE CARDIOMETRICS MEETING ARE OF GREAT
IMPORTANCE TO THE STOCKHOLDERS OF CARDIOMETRICS. ACCORDINGLY, CARDIOMETRICS
STOCKHOLDERS ARE URGED TO READ AND CAREFULLY CONSIDER THE INFORMATION PRESENTED
IN THIS PROXY STATEMENT/PROSPECTUS, AND TO COMPLETE, DATE, SIGN AND PROMPTLY
RETURN THE ENCLOSED PROXY IN THE ENCLOSED POSTAGE-PAID ENVELOPE.
 
                     STOCKHOLDERS SHOULD NOT SEND ANY STOCK
                      CERTIFICATES WITH THEIR PROXY CARDS

                      THE MERGER AND RELATED TRANSACTIONS
 
THE MERGER CONSIDERATION
 
     The Reorganization Agreement provides for the merger of a newly formed,
wholly-owned subsidiary of EndoSonics with and into Cardiometrics, with
Cardiometrics to be the surviving corporation of the Merger and thus to become a
wholly-owned subsidiary of EndoSonics. The discussion in this Proxy
Statement/Prospectus of the Merger and the description of the principal terms
and conditions of the Reorganization Agreement are subject to and qualified in
their entirety by reference to the Reorganization Agreement, a copy of which is
attached to this Proxy Statement/Prospectus as Appendix A and is incorporated
herein by reference. You are urged to read the Reorganization Agreement in its
entirety.
 
  Conversion of Shares
 
     Upon consummation of the Merger, each outstanding share of Cardiometrics
Common Stock will be converted, without any action on the part of the holder
thereof, into the right to receive the following (the "Merger Consideration"):
(i) .35 shares of EndoSonics Common Stock (the "EndoSonics Exchange Ratio");
(ii) $3.00 in cash (the "Cash Consideration"); and (iii) at least .1364 but no
more than .19 shares of CVD Common Stock (adjusted as set forth in the following
sentence, the "CVD Exchange Ratio"). If, based on the average closing prices of
EndoSonics Common Stock and CVD Common Stock for the ten trading days
immediately preceding (and including) the third trading day prior to the
Cardiometrics Meeting and using a CVD Exchange Ratio of .1364, the Merger
Consideration would be less than $8.00, the CVD Exchange Ratio will be increased
from .1364 such that the Merger Consideration shall equal $8.00, but in no event
shall the CVD Exchange Ratio exceed .19. Accordingly, because the Reorganization
Agreement does not contain a minimum value for the Merger Consideration or allow
Cardiometrics to terminate the Merger if the Merger Consideration falls below a
specified value, the value of the Merger Consideration may be lower than $8.00
per share at the time of closing. See "Summary of Merger Consideration."
 
     Shares of Cardiometrics Common Stock held by EndoSonics will be cancelled
and extinguished without any conversion thereof. Cash will be paid in lieu of
fractional shares. Based upon the capitalization of Cardiometrics and EndoSonics
as of May 30, 1997, including the cancellation of the 300,000 shares of
Cardiometrics Common Stock held by EndoSonics, the stockholders of Cardiometrics
will own EndoSonics Common Stock representing approximately 14.7% of the
EndoSonics Common Stock outstanding immediately after consummation of the
Merger.
 
  Treatment of Options
 
     Immediately prior to the consummation of the Merger, each outstanding
option under the Cardiometrics 1985 Stock Option Plan, 1995 Stock Option Plan
and 1995 Stock Incentive Plan (collectively, the "Cardiometrics Option Plans")
will, pursuant to its terms, vest in full and become exercisable for all of the
shares of Cardiometrics Common Stock at the time subject to that option, with
such accelerated vesting to be conditioned, however, upon the actual
consummation of the Merger. Each share of Cardiometrics Common Stock acquired
under the Cardiometrics Option Plans through the exercise of an outstanding
option effected immediately prior to the Merger will be canceled and
extinguished upon the consummation of the Merger and converted automatically
into the right to receive the Merger Consideration payable per share of
Cardiometrics Common Stock. However, if the Merger is not consummated, the
option exercise price paid for any shares of Cardiometrics Common Stock
purchased under the Cardiometrics Option Plans on the basis of such conditional
exercise and acceleration will be refunded by Cardiometrics, and the vesting
schedule for those shares will revert to the schedule in effect immediately
prior to such exercise and acceleration.

<PAGE>   55
 
     Upon the consummation of the Merger, each outstanding option under the
Cardiometrics Option Plans (a "Cardiometrics Option") will be assumed in part
and converted in part into the right to receive a payment from EndoSonics as
follows:
 
          Option Assumption: Each Cardiometrics Option will be assumed in part
     by EndoSonics and converted into an option to purchase that number of
     shares of EndoSonics Common Stock equal to the product of the number of
     shares of Cardiometrics Common Stock subject to that option immediately
     prior to the consummation of the Merger multiplied by 0.35 (the "EndoSonics
     Exchange Ratio") and rounded down to the nearest whole number of shares of
     EndoSonics Common Stock, and the per share exercise price for the shares of
     EndoSonics Common Stock subject to the assumed option will be equal to the
     product of (i) the quotient determined by dividing (x) the exercise price
     per share of Cardiometrics Common Stock for which such option was
     exercisable immediately prior to the consummation of the Merger by (y)
     EndoSonics Exchange Ratio and (ii) the Conversion Ratio (as defined below),
     rounded up to the nearest whole cent. Each assumed option will be fully and
     immediately exercisable for all the covered shares of EndoSonics Common
     Stock as fully-vested shares. Except for the foregoing changes effected in
     connection with the partial assumption of the outstanding options under the
     Cardiometrics Option Plans, all the terms and conditions of those options
     as in effect immediately prior to the consummation of the Merger will
     continue in full force and effect. For purposes of converting the assumed
     options into options to purchase EndoSonics Common Stock at an adjusted
     exercise price per share, the Conversion Ratio will be that fraction, the
     numerator of which is the value of the portion of the Merger Consideration
     paid in shares of EndoSonics Common Stock and the denominator of which is
     the total value of the Merger Consideration. Such valuation will be
     determined on the basis of the average of the closing prices of EndoSonics
     Common Stock and CVD Common Stock for the ten trading days ending with the
     third trading day immediately prior to the Cardiometrics Stockholders
     Meeting. EndoSonics will file a Registration Statement on Form S-8 with the
     Commission with respect to the shares of EndoSonics Common Stock issuable
     under the assumed Cardiometrics Options within five days of the Effective
     Time.
 
          Option Conversion: Upon the consummation of the Merger, the balance of
     each Cardiometrics Option will be converted into the right to receive a
     payment from EndoSonics. Such payment per option share will be equal to (i)
     the value of that portion of the Merger Consideration paid in cash and
     shares of CVD Common Stock per 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 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 assumption by EndoSonics. Such consideration
     per option share will be paid proportionately in cash and in shares of CVD
     Common Stock, in the same ratio as the value of each of those elements of
     consideration bears to the total value of the portion of the Merger
     Consideration paid in cash and CVD Common Stock per outstanding share of
     Cardiometrics Common Stock.
 
  Treatment of Warrants
 
     Each outstanding warrant to purchase shares of Cardiometrics Common Stock
(a "Cardiometrics Warrant"), pursuant to its terms, will be assumed by
EndoSonics upon the consummation of the Merger and upon payment of the same
aggregate exercise price for such warrant prior to the Merger be exerciseable
for the Merger Consideration multiplied by the number of shares of Cardiometrics
Common Stock subject to such warrant immediately prior to the Merger.
 
  Summary of Merger Consideration
 
     As described above, the number of shares of EndoSonics Common Stock into
which each outstanding share of Cardiometrics Common Stock will be converted
upon consummation of the Merger is fixed at 0.35 shares. Accordingly, based on
the capitalization of Cardiometrics on May 30, 1997, including the cancellation
of the 300,000 shares of Cardiometrics Common Stock held by EndoSonics,
EndoSonics will issue approximately 2,339,000 shares of EndoSonics Common Stock
to the former Cardiometrics stock-
 
                                       44
<PAGE>   56
 
holders, or approximately 14.7% of EndoSonics Common Stock outstanding
immediately after the Merger. The amount of cash exchanged for each share of
Cardiometrics Common Stock is fixed at $3.00. The CVD Exchange Ratio and the
value of the Merger Consideration are subject to fluctuation based upon the
market prices of EndoSonics Common Stock and CVD Common Stock. The following
tables set forth, at different market prices for EndoSonics Common Stock and CVD
Common Stock, the value of the Merger Consideration, the resulting CVD Exchange
Ratio, the total number of shares of CVD Common Stock to be distributed in
connection with the Merger and the percentage of outstanding shares of CVD
Common Stock to be held by Cardiometrics stockholders and optionholders
immediately after the Merger.
 
     The following table sets forth, at different market prices for EndoSonics
Common Stock and CVD Common Stock, the value of the Merger Consideration. This
table assumes that the average per share prices for the EndoSonics Common Stock
and CVD Common Stock for the ten trading days immediately preceding (and
including) the third trading day prior to the Cardiometrics Meeting are the same
as the per share prices for the EndoSonics Common Stock and CVD Common Stock on
the day the Merger Consideration is being valued. Note, however, that the ten
day average prices used for calculating the CVD Exchange Ratio, may be different
than closing prices on the day of the Cardiometrics Meeting. The calculation of
the CVD Exchange Ratio is described on the following page. For example, if the
ten-day average EndoSonics Common Stock price were $10.00 per share and the
ten-day average CVD Common Stock price were $8.00, the CVD Exchange Ratio will
adjust up to .1875 as described on the following page. With such adjusted CVD
Exchange Ratio, the value of the Merger Consideration, assuming a $10.00 per
share EndoSonics Common Stock price and an $8.00 per share CVD Common Stock
price, would consist of $3.50 of EndoSonics Common Stock (the $10.00 assumed
EndoSonics Common Stock price multiplied by the 0.35 EndoSonics Exchange Ratio)
plus $1.50 of CVD Common Stock (the $8.00 assumed CVD Common Stock price
multiplied by the adjusted .1875 CVD Exchange Ratio) plus $3.00 (the Cash
Consideration) which sum equals $8.00. This amount can be seen on the table
below by finding the intersection of the row showing Merger Consideration values
assuming an EndoSonics Common Stock price of $10.00 per share and the column
showing Merger Consideration values assuming CVD Common Stock prices of $8.00
per share. The actual value of the Merger Consideration may differ from the
above example. As indicated by the table, because the Reorganization Agreement
does not contain a minimum value for the Merger Consideration or allow
Cardiometrics to terminate the Merger if the Merger Consideration falls below a
specified value, the value of the Merger Consideration may be lower than $8.00
per share at the time of closing.

     The following table sets forth, at different market prices for EndoSonics
Common Stock and CVD Common Stock, the resulting CVD Exchange Ratio. The CVD
Exchange Ratio is at least .1364 but no more than .19 shares of CVD Common
Stock. If, based on the average of closing prices of EndoSonics Common Stock and
CVD Common Stock for the ten trading days immediately preceding (and including)
the third trading day prior to the Cardiometrics Meeting and using a CVD
Exchange Ratio of .1364, the Merger Consideration would be less than $8.00, the
CVD Exchange Ratio will be increased from .1364 such that the Merger
Consideration shall equal $8.00, but in no event will the CVD Exchange Ratio
exceed .19. For example, if the average per share prices for the EndoSonics
Common Stock and CVD Common Stock for the ten trading days immediately preceding
(and including) the third trading day prior to the Cardiometrics Meeting were
$10.00 and $8.00, respectively, the unadjusted value of the Merger Consideration
per share would consist of $3.50 of EndoSonics Common Stock (the $10.00 assumed
average EndoSonics Common Stock price multiplied by the 0.35 EndoSonics Exchange
Ratio) plus $1.09 of CVD Common Stock (the $8.00 assumed average CVD Common
Stock price multiplied by the unadjusted .1364 CVD Exchange Ratio) plus $3.00
(the Cash Consideration), which sum equals $7.59. Because such amount is less
than $8.00, the CVD Exchange Ratio will adjust up to .1875. With such adjusted
CVD Exchange Ratio, the value of the Merger Consideration, assuming a $10.00 per
share average EndoSonics Common Stock price and an $8.00 per share average CVD
Common Stock price, would consist of $3.50 of EndoSonics Exchange Common Stock
(the $10.00 assumed average EndoSonics Common Stock price multiplied by the 0.35
Endosonics Exchange Ratio) plus $1.50 of CVD Common Stock (the $8.00 assumed
average CVD Common Stock price multiplied by the adjusted .1875 CVD Exchange
Ratio) plus $3.00 (the Cash Consideration) which sum equals $8.00. This amount
can be seen on the table below by finding the intersection of the row showing
CVD Exchange Ratios assuming an average EndoSonics Common Stock price of $10.00
per share and the column showing CVD Exchange Ratios assuming an average CVD
Common Stock prices of $8.00 per share. The actual value of the CVD Exchange
Ratio may differ from the above example.

     As an example of the consideration to be provided to stockholders of
Cardiometrics in connection with the Merger, based upon the average of the
closing prices of EndoSonics Common Stock and CVD Common Stock for the ten
trading days immediately preceding (and including) June 11, 1997 of $11.36875
and $8.15, respectively, each share of Cardiometrics Common Stock would be
converted into the right to receive 0.35 shares of EndoSonics Common Stock,
 .1364 shares of CVD Common Stock and $3.00 of cash, which, based on the closing
prices of EndoSonics Common Stock and CVD Common Stock on June 11, 1997 of
$11.125 and $8.50, respectively, was equal to a per share consideration valued
at $8.05.

     The number of shares of stock to be issued and the actual value of the
Merger Consideration may differ from the above example since the number of
shares to be issued will not be determined until three trading days prior to the
Cardiometrics Meeting and since the actual value of the Merger Consideration is
dependent upon the market prices of EndoSonics Common Stock and CVD Common
Stock, which are subject to fluctuation.
 
TREATMENT OF EMPLOYEE STOCK PURCHASE PLAN
 
     Outstanding purchase rights under the Cardiometrics Employee Stock Purchase
Plan (the "ESPP") will be exercised upon the earlier of (i) the next scheduled
purchase date under the ESPP (October 31, 1997) or (ii) immediately prior to the
consummation of the Merger, and each participant in the ESPP will accordingly be
issued shares of Cardiometrics Common Stock at that time, and each share of
Cardiometrics Common Stock so issued will be canceled and extinguished upon the
consummation of the Merger and converted automatically into the right to receive
the Merger Consideration payable per share of Cardiometrics Common Stock. The
ESPP will terminate with such exercise date, and no purchase rights will
subsequently be granted or exercised under the ESPP; provided that if the Merger
is not consummated then the ESPP will not be terminated and purchase rights will
be granted.
 
EXCHANGE OF CERTIFICATES
 
     Within five business days after the Effective Time, a letter of transmittal
with instructions will be mailed to each Cardiometrics stockholder for use in
exchanging Cardiometrics Common Stock certificates for the Merger Consideration.
Upon surrender of a Cardiometrics Common Stock certificate for cancellation to
the exchange agent in connection with the Merger, Chase Mellon Shareholder
Services, together with such letter of transmittal, duly completed and validly
executed in accordance with the instructions thereto, the holder of such
certificate will be entitled to receive in exchange therefor a certificate
representing the number of whole shares of EndoSonics Common Stock equal to 0.35
multiplied by the number of shares subject to the Cardiometrics Common Stock
certificate being exchanged, a certificate representing the number of whole
shares of CVD Common Stock equal to the CVD Exchange Ratio (initially set at
0.1364, but subject to adjustment as set forth above in "-- The Merger
Consideration -- Conversion of Shares") multiplied by the number of shares
subject to the Cardiometrics Common Stock certificate being exchanged and cash
in the amount of the number of shares subject to the Cardiometrics Common Stock
certificate being exchanged multiplied by $3.00. No fraction of a share of
EndoSonics Common Stock or CVD Common Stock will be issued, but in lieu thereof
each holder of shares of Cardiometrics Common Stock who would otherwise be
entitled to a fraction of a share of EndoSonics Common Stock or CVD Common Stock
(after aggregating all fractional shares of EndoSonics Common Stock or CVD
Common Stock to be received by such holder) will receive from EndoSonics an
amount of cash, rounded up to the nearest whole cent, equal to the product of
(i) such fraction, multiplied by (ii) the average closing price of a share of
EndoSonics Common Stock or CVD Common Stock, as applicable, for the ten most
recent days that EndoSonics Common Stock or CVD Common Stock, as applicable, has
traded ending on the trading day immediately prior to the Effective Time, as
reported on the Nasdaq National Market.
 
     Immediately after the Effective Time, each outstanding Cardiometrics Common
Stock certificate will be deemed for all corporate purposes, other than the
payment of dividends, to evidence the ownership of the number of full shares of
EndoSonics Common Stock and CVD Common Stock into which such shares of
Cardiometrics Common Stock shall have been so converted as a result of the
Merger and the right to receive an amount in cash in lieu of the issuance of any
fractional shares. No dividends or other distributions with respect to
EndoSonics Common Stock or CVD Common Stock with a record date after the
Effective Time will be paid to the holder of any unsurrendered Cardiometrics
Common Stock certificate with respect to the shares of EndoSonics Common Stock
or CVD Common Stock represented thereby until the holder of record of such
certificate surrenders such certificate. Subject to applicable law, following
surrender of any such certificate, there will be paid to the record holder of
the certificates representing whole shares of EndoSonics Common Stock or CVD
Common Stock issued in exchange therefor, without interest, at the time of such
surrender, the amount of any such dividends or other distributions with a record
date after the Effective Time theretofore payable with respect to such shares of
EndoSonics Common Stock or CVD Common Stock.
 
                                       48

     If any certificate for shares of EndoSonics Common Stock or CVD Common
Stock is to be issued in a name other than that in which the Cardiometrics
Common Stock certificate surrendered in exchange therefor is registered, it will
be a condition of the issuance thereof that the Cardiometrics Common Stock
certificate so surrendered be properly endorsed and otherwise in proper form for
transfer and that the person requesting such exchange have paid to EndoSonics or
any agent designated by it any transfer or other taxes required by reason of the
issuance of a certificate for shares of EndoSonics Common Stock or CVD Common
Stock in any name other than that of the registered holder of the Cardiometrics
Common Stock certificate surrendered, or established to the satisfaction of
EndoSonics or any agent designated by it that such tax has been paid or is not
payable.
 
         HOLDERS OF CARDIOMETRICS COMMON STOCK CERTIFICATES SHOULD NOT
        SUBMIT THEIR CERTIFICATES FOR EXCHANGE UNTIL THEY HAVE RECEIVED
         THE LETTER OF TRANSMITTAL AND INSTRUCTIONS REFERRED TO ABOVE.
 
NOTIFICATION REGARDING OPTIONS AND WARRANTS
 
     Within 10 business days following the Effective Time, EndoSonics will issue
to each person who, immediately prior thereto was a holder of an outstanding
Cardiometrics Option or Cardiometrics Warrant a document evidencing the
assumption of such option or warrant by EndoSonics. Such assumption will be
automatic and no action will be required on the part of the option holder or
warrant holder to convert such holder's Cardiometrics Option or Cardiometrics
Warrant into an option or warrant to purchase shares of EndoSonics Common Stock.
 
BACKGROUND OF THE MERGER
 
     In the spring of 1994 EndoSonics approached Cardiometrics to discuss a
possible business combination between Cardiometrics and EndoSonics. In response
to EndoSonics' inquiry, Cardiometrics' Board of Directors (the "Cardiometrics
Board") retained Goldman, Sachs & Co., an investment banking firm ("Goldman"),
to review and pursue opportunities for the sale of Cardiometrics, including an
evaluation of the EndoSonics inquiry. Beginning in June 1994, Cardiometrics and
Goldman prepared a confidential offering memorandum and contacted more than
fifty potential buyers, including companies in the fields of cardiology,
interventional cardiology, medical devices and catheterization laboratory
capital equipment. After Cardiometrics' engagement of Goldman, EndoSonics ceased
serious discussions with Cardiometrics regarding a potential business
combination stating, among other reasons, that it had no intention of
participating in an auction or competitive bidding process. In September 1994,
in response to the ongoing effort to sell Cardiometrics, Goodman Co. Ltd.
("Goodman"), Cardiometrics' Japanese distributor, negotiated an extension of the
term of its distribution rights until 1999 and committed to make a $5 million
equity investment in Cardiometrics. Following the failure to generate any
meaningful offers to purchase Cardiometrics and Goodman's funding of the first
installment of its commitment to purchase equity, Cardiometrics terminated the
Goldman engagement in October 1994 and ceased actively marketing the company for
sale.
 
     In November 1995, Cardiometrics consummated its initial public offering,
selling 2,200,000 shares of its common stock at $9.00 per share with Dillon Read
as lead manager and Needham & Company, Inc. ("Needham") as co-manager. During
the process leading up to Cardiometrics' initial public offering, no potential
buyers approached Cardiometrics regarding a possible purchase of Cardiometrics
prior to its initial public offering. Since Cardiometrics' initial public
offering, Cardiometrics had informal discussions with various companies to
consider potential opportunities for cooperation in the development, marketing,
sales and distribution of Cardiometrics' products or the potential acquisition
of Cardiometrics.
 
     In early July 1996, Mr. Jeffrey Barnes of Needham called Mr. Reinhard
Warnking, President and Chief Executive Officer of EndoSonics, to discuss the
merits of a possible business combination between EndoSonics and Cardiometrics.
 
     On July 29, 1996, Mr. Bernard Lirola of Needham called Dr. Menahem Nassi,
President and Chief Executive Officer of Cardiometrics, inquiring whether
Cardiometrics would be interested in discussing a strategic relationship with
EndoSonics, including a possible merger between EndoSonics and Cardiometrics.
During early August 1996 there were several additional telephone conversations
 
                                       49
<PAGE>   61
 
between Mr. Lirola and Dr. Nassi and Robert Y. Newell, IV, Chief Financial
Officer and Vice President, Finance and Administration, of Cardiometrics,
regarding a possible business combination.
 
     On August 5, 1996, the EndoSonics Board of Directors (the "EndoSonics
Board") held a regular meeting, at which, among other matters, the EndoSonics
Board discussed the merits of a possible business combination between EndoSonics
and Cardiometrics.
 
     On August 20, 1996, Dr. Nassi and Mr. Warnking met in Oakland, California
to discuss the business position of each company, the complementary nature of
anatomical and physiologic measurements in the cardiac catheterization
laboratory and the potential benefits of a business combination between the
companies, including the potential market for devices combining anatomical and
physiologic measurements. These discussions did not include any discussion of
financial terms.
 
     On September 24, 1996, the Cardiometrics Board held a regular meeting at
which, among other matters, Dr. Nassi advised the Board concerning the
discussions with EndoSonics and its financial advisor.
 
     On October 1, 1996, Dr. Nassi, Mr. Newell, Mr. Warnking and Donald Huffman,
Chief Financial Officer of EndoSonics, met in Rancho Cordova, California to
discuss the issues and opportunities facing both companies and the benefits and
obstacles of a business combination of the two companies. These discussions
included a review of manufacturing, staffing and distribution capabilities of
the two companies, but did not include any discussion of financial terms.
 
     On October 7, 1996, Dr. Nassi, Mr. Newell and Michael Sorna, Vice President
of International Sales and Operations of Cardiometrics, met, in Huntington
Beach, California, with Mr. Masahiko Kaneko of Kaneko Enterprises, the U.S.
representative for Goodman. Mr. Kaneko was informed of the possibility of an
acquisition of Cardiometrics by a third-party with products that are competitive
with products distributed by Goodman in Japan and with different distribution
relationships in Japan. Following this meeting, Mr. Kaneko helped arrange for
management of Cardiometrics to meet with Goodman executives.
 
     On October 10, 1996, the Cardiometrics Board held a special telephonic
meeting to discuss the status of the discussions with EndoSonics and the
possibility of other business combinations.
 
     In a series of meetings on October 12, 1996 through October 14, 1996, Dr.
Nassi, Mr. Newell and Mr. Sorna met in Nagoya, Japan with Mr. Akira Yamamoto,
President of Goodman, Mr. Tsurumoto, Director, Marketing and Sales of Goodman
and Mr. Kimura, Director, General Administration of Goodman to discuss a
possible business combination between Cardiometrics and Goodman. At the
conclusion of the meetings, Goodman, which was preparing for a December 1996
initial public offering in Japan, indicated that it could not presently proceed
with any type of transaction with Cardiometrics, and the earliest it could
possibly consider any possible transaction was after its initial public offering
was completed.
 
     From October 17, 1996 through October 20, 1996, Dr. Nassi and Mr. Warnking
attended the Phoenix 1996 CEO Forum for Medical Device Companies. During the
course of this conference, Dr. Nassi and Mr. Warnking had several informal
discussions regarding the potential for a business combination of EndoSonics and
Cardiometrics. These discussions included an overview of products, distribution
channels and new product opportunities, but did not include any discussion of
financial terms.
 
     In advance of the scheduled October 22, 1996 meeting of the parties,
EndoSonics proposed that each party sign a confidentiality agreement. However,
among other terms of the proposed confidentiality agreement, Cardiometrics
objected to a provision requiring Cardiometrics to cease all discussions
regarding a possible sale of Cardiometrics to anyone other than EndoSonics and
to not enter into such discussions. Since the confidentiality agreements were
not signed, the parties continued their discussions based on publicly available
information.
 
     On October 22, 1996. Mr. Warnking, Michael Henson, then the Chairman of the
Board of Directors of EndoSonics and currently a member of the EndoSonics Board,
and Mr. Huffman met with Dr. Nassi and Mr. Newell to discuss the possibility of
a business combination. At this meeting the strategy and operating objectives of
each company was discussed. The parties also discussed the 1994
 
                                       50
<PAGE>   62
 
effort by EndoSonics to acquire Cardiometrics, and in particular both parties'
dissatisfaction with that process. In this regard, Dr. Nassi described the
substantial disruption to Cardiometrics' relationships with employees,
customers, distributors and researchers which followed EndoSonics' 1994 inquiry
regarding the acquisition of Cardiometrics, including difficulty recruiting,
retaining and motivating employees and researchers, concerns of current and
potential customers regarding the support for Cardiometrics' products, and
diminished efforts by distributors fearing they would lose distribution rights
following an acquisition, and Dr. Nassi insisted that EndoSonics make a
meaningful and substantial financial offer if EndoSonics desired to currently
pursue a merger.
 
     On November 5, 1996, the EndoSonics Board held a regular meeting, at which,
among other matters, the EndoSonics Board again discussed the merits of a
possible business combination between EndoSonics and Cardiometrics. At this
meeting, representatives of Needham gave a presentation regarding the cardiology
industry in general and the benefits and risks of a possible merger with
Cardiometrics, as well as possible financial terms for an acquisition, including
alternative mixes of cash and securities to constitute the merger consideration.
At the conclusion of this meeting, the EndoSonics Board authorized EndoSonics'
senior management to continue negotiating with Cardiometrics.
 
     On November 21, 1996, the Cardiometrics Board held a regular meeting, at
which, among other matters, the Cardiometrics Board discussed Cardiometrics'
current business, its prospects, and its alternatives for various strategic
relationships involving third parties, including the status of discussions with
EndoSonics and Goodman regarding a possible acquisition of Cardiometrics and the
fact that Cardiometrics had been unable, after several months of effort, to
obtain a U.S. distribution partner despite inquiries to or discussions with the
following major interventional cardiology companies: Advanced Cardiovascular
Systems, Inc., a subsidiary of Guidant Corporation ("ACS/Guidant"), Medtronic,
Inc. ("Medtronic"), Boston Scientific Corporation and Cordis/Johnson & Johnson.
ACS/Guidant was then conducting due diligence on Cardiometrics and its products
but had not yet begun negotiating any terms for a distribution arrangement.
Medtronic had completed a due diligence review and declined to discuss
distribution arrangements. Inquiries to Boston Scientific Corporation and
Cordis/Johnson & Johnson regarding their interest in pursuing a distribution
arrangement with Cardiometrics had been declined or not responded to. (Following
the public announcement of the Reorganization Agreement, Cardiometrics,
EndoSonics and Cordis/Johnson & Johnson reached an agreement for Cordis/Johnson
& Johnson to co-distribute Cardiometrics' products in the United States. See
"Cardiometrics Business -- Sales and Marketing.") The Cardiometrics Board also
discussed the possibility of implementing a shareholder rights plan and amending
its bylaws to protect Cardiometrics' stockholders from any coercive or abusive
takeovers. This discussion included a review by Cardiometrics' legal counsel of
directors' duties and responsibilities in considering the adoption of a
shareholder rights plan and in considering proposals for business combinations.
 
     On November 26, 1996, the EndoSonics Board held a special telephonic
meeting to discuss the status of discussions with Cardiometrics, including
discussions regarding mix of consideration and integration issues.
 
     On December 3, 1996, the Cardiometrics Board held a special telephonic
meeting at which, among other matters, the Cardiometrics Board further
considered whether to adopt a shareholder rights plan and amend its bylaws.
Following discussion, the Cardiometrics Board adopted a shareholder rights plan
and amended its bylaws.
 
     On December 7, 1996, Mr. Warnking and Mr. Roger Salquist, the recently
elected Chairman of the Board of Directors of EndoSonics, met with Dr. Nassi and
Mr. Newell in Burlingame, California to discuss possible financial terms for a
business combination. The meeting concluded without any agreement on financial
or other terms of a merger.
 
     On December 9, 1996, the Cardiometrics Board held a special telephonic
meeting at which, among other matters, Dr. Nassi and Mr. Newell briefed the
Cardiometrics Board on the December 7, 1996 meeting with EndoSonics. Dr. Nassi
also reported that Medtronic had not responded to further inquiries regarding a
U.S. distribution arrangement and that ACS/Guidant had yet to propose any terms
for such an arrangement. The Cardiometrics Board, among other matters, discussed
the substantial disruption to its relationships with employees, customers,
distributors and researchers
 
                                       51
<PAGE>   63
 
following Goldman's 1994 failed auction of Cardiometrics, the risks to
Cardiometrics' efforts to secure a U.S. distribution partner which would be
created by again attempting a public or active auction of Cardiometrics, and
EndoSonics' insistence that it would again cease negotiations with Cardiometrics
if the company decided to actively auction itself. The Cardiometrics Board also
discussed the benefits of retaining an investment banking firm to assist the
Cardiometrics Board in evaluating the potential financial terms discussed by
EndoSonics and to otherwise act as the Cardiometrics Board's financial advisor.
After further discussion, the Board authorized the engagement of Dillon Read as
Cardiometrics' financial advisor.
 
     On December 18, 1996, Cardiometrics Board held a special telephonic meeting
to discuss the status of discussion with EndoSonics. At this meeting, after
reports from Cardiometrics' senior management and a review by Cardiometrics'
legal counsel of directors' duties and responsibilities in considering proposals
for business combinations, the Cardiometrics Board heard a presentation from
representatives of Dillon Read. This presentation covered the cardiology
industry in general and interventional cardiology markets in particular and
analyzed recent merger and acquisition activity in the medical device industry.
Dillon Read also presented a general overview of Cardiometrics, EndoSonics and
CVD, outlined various methods of determining the intrinsic value of
Cardiometrics, and analyzed EndoSonics' initial proposal of financial terms for
a transaction. The Cardiometrics directors then had a lengthy and detailed
discussion of these issues, focusing on the various strategic options and
alternatives available to Cardiometrics, including the benefits and detriments
of remaining independent and the risks and benefits of shopping the company or
conducting an auction. At the conclusion of the meeting, the Cardiometrics Board
directed Cardiometrics' senior management and Dillon Read to continue
negotiating with EndoSonics.
 
     On December 19, 1996, a meeting was held in Rancho Cordova, California
between Messrs. Salquist, Warnking, and Huffman of EndoSonics, Dr. Nassi and Mr.
Newell of Cardiometrics and representatives of Needham and Dillon Read. The
underlying basis and principles for the proposed merger, including the strategic
rationales for combining the two companies, were reviewed and alternative
financial terms for structuring the transaction were discussed, including
alternative mixes of cash and securities to constitute the merger consideration,
as well as the size and timing of payment of the break-up fee. The parties could
not agree on basic financial terms and completed the meeting with no plans to
pursue an agreement.
 
     Between December 20, 1996 and December 24, 1996, there were numerous
telephone conferences between the companies and their respective financial
advisors regarding potential financial terms of a transaction, including
alternative mixes of cash and securities to constitute the merger consideration,
as well as the size and timing of payment of the break-up fee.
 
     On December 27, 1996, the EndoSonics Board held a special telephonic
meeting to discuss the status of discussions with Cardiometrics. EndoSonics'
management, together with its financial advisors, updated the EndoSonics Board
regarding possible financial terms for the transaction and potential synergies
between the two companies.
 
     Also on December 27, 1996, Cardiometrics Board held a special telephonic
meeting to discuss the status of the discussions with EndoSonics. The
Cardiometrics Board authorized Cardiometrics' management to continue negotiating
with EndoSonics, including negotiation of a definitive agreement, and to pursue
due diligence reviews of EndoSonics and CVD.
 
     On January 2, 1997, the EndoSonics Board held a special telephonic meeting
to discuss the status of discussions with Cardiometrics. The EndoSonics Board
authorized EndoSonics' management to continue negotiating with Cardiometrics,
including negotiation of a definitive agreement and due diligence review of
Cardiometrics.
 
     On January 3, 1997, EndoSonics and Cardiometrics executed a Mutual
Confidentiality Agreement. An initial draft of the Reorganization Agreement was
distributed to both companies and their legal and financial advisors on January
6, 1997.
 
     On January 8, 1997, January 9, 1997 and January 10, 1997, representatives
of the management of EndoSonics and Cardiometrics and their respective financial
and legal advisors met to conduct due diligence reviews of each other and of CVD
and to negotiate terms of the Reorganization Agreement.
 
                                       52
<PAGE>   64
 
The parties ceased negotiations on January 10, 1997 as a result of their failure
to agree on the numerous material terms in the draft of the Reorganization
Agreement, including price, the mix of securities and cash constituting the
merger consideration, size and timing of payment of the break-up fee and terms
of the Stock Option Agreement, including the number of shares subject to the
option and the extent of EndoSonics' economic interest in the underlying shares,
if any.
 
     On January 13, 1997, the Cardiometrics Board held a special telephonic
meeting to discuss the status of discussions with EndoSonics and Goodman.
 
     In response to a January 14, 1997 letter from Mr. Yamamoto to Dr. Nassi
expressing Goodman's desire to negotiate an acquisition of Cardiometrics, on
January 16, 1997 through January 18, 1997, Dr. Nassi, Mr. Newell and
representatives of Dillon Read met in Osaka, Japan with management of Goodman
and representatives of Nikko Securities, Goodman's financial advisor. On January
18, 1997, the management of Cardiometrics and Goodman reached agreement on a
one-page, non-binding term sheet for a proposed acquisition of Cardiometrics by
Goodman.
 
     On January 20, 1997, Dr. Nassi informed Mr. Warnking of the possibility of
another acquiror of Cardiometrics. After this discussion, EndoSonics, directly
and through its financial advisors, insisted that Cardiometrics immediately
either negotiate a definitive agreement with EndoSonics or else EndoSonics would
not resume negotiations. To induce Cardiometrics to join EndoSonics in
immediately negotiating a definitive agreement, EndoSonics agreed to delete from
the draft Reorganization Agreement any reduction in stock exchange ratios in the
event the total value of the Merger Consideration increased after the execution
of the Reorganization Agreement. In return, EndoSonics agreed to continue
negotiating only if Cardiometrics agreed to pay EndoSonics an expense
reimbursement of $1 million in the event Cardiometrics signed a definitive
acquisition agreement with the other party which had expressed interest in
acquiring Cardiometrics.
 
     Later on January 20, 1997, Dr. Nassi received a facsimile letter from Mr.
Yamamoto indicating that the terms of the January 18, 1997 term sheet were not
approved by Goodman's Board of Directors and would need to be renegotiated
through a representative of Goodman in the United States. On January 23, 1997,
without having received any specific proposals to renegotiate the term sheet,
Dr. Nassi received another facsimile letter from Mr. Yamamoto indicating that,
due to factors unrelated to Cardiometrics, Goodman was no longer interested or
able to pursue an acquisition of Cardiometrics.
 
     On January 22, 1997, management representatives of EndoSonics and
Cardiometrics together with their respective financial and legal advisors met in
San Francisco, California to negotiate the key financial terms of a definitive
agreement. Negotiation of the Reorganization Agreement continued on January 23,
1997 and January 24, 1997 via telephone conference calls and at the Palo Alto,
California offices of EndoSonics' legal counsel.
 
     On January 25, 1997, the EndoSonics Board held a special telephonic
meeting, at which, following presentations by its financial and legal advisors,
the EndoSonics Board, with one director abstaining, among other things (i)
determined that it would be in the best interests of the EndoSonics stockholders
to consummate the Merger, (ii) approved the form and terms of the Reorganization
Agreement, and (iii) authorized EndoSonics' officers to undertake all acts
necessary or desirable to effectuate the Merger.
 
     On the morning of January 25, 1997, the Cardiometrics Board held a special
telephonic meeting to consider the proposed transaction with EndoSonics.
Cardiometrics' management and its legal and financial advisors discussed with
the Cardiometrics Board the course of negotiations and the changes to the terms
of the Merger since the last Cardiometrics Board meeting and reviewed the
detailed terms of the Reorganization Agreement. Dr. Nassi also reported on the
status of recent negotiations with ACS/Guidant regarding a non-binding term
sheet for U.S. distribution of Cardiometrics' products. After extensive
discussion, including discussion of the potential risks and benefits of the
proposed Merger, the Cardiometrics Board adjourned and agreed to meet again on
January 26, 1997.
 
     On January 26, 1997, the Cardiometrics Board held a special telephonic
meeting to discuss the proposed merger. A representative from Dillon Read
delivered its oral opinion (which was subsequently confirmed in writing) that,
as of such date, the consideration to be received by the holders of
Cardiometrics Common Stock pursuant to the terms of the Agreement and Plan of
Reorganization, as
 
                                       53
<PAGE>   65
 
it existed prior to its amendment (including the Amendment referred to below),
was fair to such holders from a financial point of view. See "-- Fairness
Opinion of Dillon Read." Cardiometrics' financial advisor and legal counsel
reviewed the final draft of the Reorganization Agreement and the resolution of
previously outstanding issues relating thereto and explained a new request by
EndoSonics that Cardiometrics covenant to reduce the number of Cardiometrics'
stock options assumed in the Merger to reduce the number of EndoSonics shares
issuable in the Merger, with the effect that EndoSonics would not be required to
obtain its stockholders' approval in order to consummate the Merger. After
consideration and discussion of the presentations of its financial and legal
advisors, and on the express condition that Cardiometrics not covenant to reduce
the number of options assumed in the Merger, the Cardiometrics Board unanimously
(i) determined that the terms of the Merger were fair to, and in the best
interests of, the holders of the Cardiometrics Common Stock from a financial
point of view, (ii) approved the terms of the Reorganization Agreement, (iii)
authorized Cardiometrics' officers to undertake all acts necessary or desirable
to effectuate the Merger, (iv) ratified and approved all actions taken
previously by any officer or director of Cardiometrics in connection with the
Merger and (v) recommended approval of the Reorganization Agreement by the
holders of the Cardiometrics Common Stock.
 
     Immediately following the Cardiometrics Board meeting, Dr. Nassi informed
Mr. Warnking of the Cardiometrics Board's approval of the Merger provided that
Cardiometrics not covenant to reduce the number of EndoSonics shares issued or
issuable upon consummation of the Merger. A number of telephone conferences
among Mr. Warnking and Dr. Nassi and the respective financial and legal advisors
of EndoSonics and Cardiometrics ensued concerning this issue. During these
conferences, Mr. Warnking further stated that EndoSonics' offer to enter into
the Reorganization Agreement would only remain open through January 26, 1997.
 
     Later on January 26, 1997, the Cardiometrics Board held another special
telephonic meeting to consider the Reorganization Agreement with the additional
covenants regarding encouraging stock option exercises. After further
consideration and discussion, the Cardiometrics Board, with one Director
abstaining, (i) determined that the terms of the Merger were fair to, and in the
best interests of, the holders of the Cardiometrics Common Stock from a
financial point of view, (ii) approved the terms of the Reorganization Agreement
(including mutual covenants of EndoSonics and Cardiometrics regarding
encouraging stock option exercises prior to the Effective Time of the Merger),
(iii) authorized Cardiometrics' officers to undertake all acts necessary or
desirable to effectuate the Merger, (iv) ratified and approved all actions taken
previously by any officer or director of Cardiometrics in connection with the
Merger and (v) recommended approval of the Reorganization Agreement by the
holders of the Cardiometrics common stock.
 
     Following this Cardiometrics Board meeting, the Reorganization Agreement
was signed.
 
     On May 15, 1997, a meeting was held in San Francisco, California between
representatives of EndoSonics and Cardiometrics. Messrs. Salquist, Warnking,
Huffman and Edward M. Leonard, an EndoSonics director and a member of Brobeck,
Phleger & Harrison LLP, EndoSonics' counsel, represented EndoSonics and Dr.
Nassi, Mr. Newell, H. Raymond Wallace, Chairman of the Board of Cardiometrics
and a representative of Cardiometrics' counsel represented Cardiometrics. The
parties discussed the advisability of amending the Reorganization Agreement to
simplify the transaction, to eliminate the provision enabling Cardiometrics to
terminate the Reorganization Agreement if the total merger consideration was
below $8.00 per share (the "Termination Right") and to alter the consideration
to be paid by EndoSonics. EndoSonics proposed that the mix of the merger
consideration be changed to include more cash and fewer shares of CVD Common
Stock, but that the total value of the merger consideration not change. No
agreement was reached.
 
     On May 16, 1997, the Cardiometrics Board held a special telephonic meeting
to consider EndoSonics' proposal for amending the Reorganization Agreement.
After considering the matter, the Cardiometrics Board authorized its management
to meet with representatives of EndoSonics to propose an amendment to the
Reorganization Agreement to (i) increase the total value of the merger
consideration based on the then prevailing prices of EndoSonics and CVD Common
Stock, (ii) modify
 
                                       54

the merger consideration by increasing the cash component and decreasing the
component attributable to CVD Common Stock and (iii) eliminate the Termination
Right.
 
     On May 16, 1997, Messrs. Salquist, Warnking, Huffman, Newell and Dr. Nassi
met again in San Francisco, California. Cardiometrics proposed that if
EndoSonics would increase the cash portion of the consideration, increase the
total value of the merger consideration (as currently valued) and modify the
merger consideration by increasing the cash component and decreasing the
component attributable to CVD Common Stock, Cardiometrics would agree to
eliminate the Termination Right.
 
     Various telephone calls were held among EndoSonics Board members and Mr.
Warnking on May 17 and 18, and on May 19, 1997, the EndoSonics Board held a
special telephonic meeting at which, following presentations by its financial
and legal advisors, the EndoSonics Board unanimously, among other things, (i)
determined that it would be in the best interests of the EndoSonics stockholders
to approve an amendment to the Reorganization Agreement, (ii) approved the form
and terms of Amendment No. 2 to the Reorganization Agreement (the "Amendment"),
and (iii) authorized EndoSonics' officers to undertake all acts necessary or
desirable to effectuate the Merger. The Amendment modified the original merger
consideration and eliminated the Termination Right.
 
     Various telephone calls were held among members of the Cardiometrics Board
and Cardiometrics' financial and legal advisors between May 16, 1997 and May 20,
1997 to discuss an amendment to the Reorganization Agreement. In the afternoon
on May 20, 1997, the Cardiometrics Board held a special telephonic meeting to
consider amending the Reorganization Agreement which was attended by the
Cardiometrics Board, Mr. Newell and Cardiometrics' financial and legal advisors.
After presentations by Cardiometrics' management and its legal advisors, but not
its financial advisor, the Cardiometrics Board unanimously (i) determined that
the Merger Consideration provided for by the Amendment was more favorable to
Cardiometrics Stockholders than the original merger consideration, (ii)
determined that it was fair to and in the best interests of holders of
Cardiometrics Common Stock from a financial point of view to modify the terms of
the Reorganization Agreement as set forth in the Amendment and (iii) authorized
Cardiometrics officers to undertake all acts necessary or desirable to
effectuate the Merger, including entering into the Amendment. See "Reasons for
the Merger -- Cardiometrics' Reasons for the Merger; Recommendation of
Cardiometrics' Board of Directors -- Terms of the Reorganization
Agreement -- Merger Consideration" for factors considered by the Cardiometrics
Board in determining that the Merger Consolidation was more favorable to
Cardiometrics stockholders than the original merger consideration. The
Cardiometrics Board did not request or obtain an updated fairness opinion from
Dillon Read that the Merger Consideration was fair to Cardiometrics stockholders
from a financial point of view. Among the factors considered by the
Cardiometrics Board in not requesting an updated fairness opinion were (i) that
the value of the Merger Consideration was higher than the original consideration
on January 24, 1997, the last trading day before the Board approved the
Agreement and Plan of Reorganization, on May 20, 1997, the day the Board
approved the Amendment and on average between such dates, (ii) that cash
represented a larger portion and CVD Common Stock a smaller portion of the
Merger Consideration than the original merger consideration, which the Board
felt tended to make the Merger Consideration less complicated to understand and
which reduced fluctuations in the value of the Merger Consideration compared to
the original merger consideration, particularly, as a result of declines in the
value of EndoSonics and CVD Common Stock, and (iii) that an updated fairness
opinion would increase the time and cost of completing the Merger.
 
     In eliminating the Termination Right, the Cardiometrics Board determined
that it would be impractical to resolicit approval of Cardiometrics stockholders
to waive the Termination Right if the value of the Merger Consideration was less
than $8.00 per share at the time of the Closing. Accordingly, the Board
determined to eliminate the Termination Right and seek the approval of
Cardiometrics stockholders at the present time to approve the Merger even if the
value of the Merger Consideration is less than $8.00 at the time of the Closing.
 
     Following this Cardiometrics Board meeting, Amendment No. 2 to the
Reorganization Agreement was signed.

REASONS FOR THE MERGER
 
  EndoSonics' Reasons for the Merger.
 
     The EndoSonics Board has identified several potential benefits of the
Merger that it believes will contribute to its success. EndoSonics has been
seeking to leverage its medical device development, manufacturing and
distribution expertise to expand, through acquisition or strategic alliances,
into complementary markets such as other diagnostic, therapeutic or imaging
markets. EndoSonics believes that the business of Cardiometrics meets this
criteria for complementary expansion. Among other things, the EndoSonics Board
and management considered the following factors: (i) Cardiometrics products are
based on complementary ultrasound technology, and together with EndoSonics
products, will provide the capability to offer interventional cardiologists both
anatomical (imaging) and physiological (functional) tools for assessment and
treatment of coronary artery disease; (ii) the combined organization is expected
to have increased presence in the cardiac catheterization laboratory by offering
both integrated intracoronary ultrasound imaging and Doppler flow technology;
(iii) both companies manufacture highly miniaturized products in a similar clean
room environment allowing for consolidation of certain manufacturing activities
and resulting cost reductions; (iv) Cardiometrics products address, pre- and
post-interventional cardiology, a market that EndoSonics believes offers
attractive future growth potential; (v) Cardiometrics has established effective
international sales channels to address its market which EndoSonics believes
will be complementary to EndoSonics' existing international sales channels, in
particular the combined organization hopes to leverage both companies' existing
relationships with Cordis as a U.S. and European distributor; (vi) EndoSonics
believes that its domestic sales and marketing structure could be used to
accelerate the expansion of the sale of Cardiometrics' products in domestic
markets and (vii) EndoSonics believes that its greater resources, including
research and development personnel and working capital, should be able to
further assist Cardiometrics in maintaining and enhancing its market position.
 
     In approving the Reorganization Agreement, as part of the due diligence
process, the EndoSonics Board considered the information about Cardiometrics
available to it from Cardiometrics management and interviews with Cardiometrics
customers, an assessment of Cardiometrics' technology, resources, distribution
network, and financial condition, and information contained in Cardiometrics'
filings with the Commission. In doing so, the EndoSonics Board not only
considered the benefits that could arise from the Merger, but also considered
certain adverse effects relating to the Merger, including the dilution to
EndoSonics Stockholders resulting from the issuance of the shares of EndoSonics
Common Stock pursuant to the Merger, certain nonrecurring costs that would
result from the Merger, and the risks inherent in any merger, including the risk
that the businesses of EndoSonics and Cardiometrics will not be able to be
successfully integrated, and other risks and uncertainties relating to the
business of EndoSonics and Cardiometrics, including without limitation those
described herein under "Risk Factors".
 
     In view of the wide variety of factors considered by the EndoSonics Board,
the EndoSonics Board did not find it practicable to quantify or otherwise assign
relative weights to the specific factors considered in approving the Merger.
However, after taking into account all of the factors set forth above, the
EndoSonics Board determined that the Merger was in the best interests of
EndoSonics and its stockholders and that EndoSonics should proceed with the
Merger.
 
  Cardiometrics' Reasons for the Merger; Recommendation of Cardiometrics' Board
of Directors
 
     The Cardiometrics Board has determined that the terms of the Reorganization
Agreement and the transactions contemplated thereby are fair to, and in the best
interests of, Cardiometrics and its stockholders. Accordingly, the Cardiometrics
Board has approved the Reorganization Agreement and recommends that the
stockholders of Cardiometrics vote FOR approval and adoption of the
Reorganization Agreement and the consummation of the Merger. In reaching its
determination, the Cardiometrics Board consulted with Cardiometrics' management,
as well as its legal counsel and financial advisor, and considered a number of
factors, including the potential benefits arising from the Merger, the terms of
the Reorganization Agreement, the results of its due diligence analyses and
potentially negative factors arising from the Reorganization Agreement and
Merger.
 
                                       56
<PAGE>   68
 
     Potential Benefits. The Cardiometrics Board believes the Merger may be
beneficial in several respects:
 
          Industry Consolidation. The Cardiometrics Board believes that the
     consolidation taking place among suppliers of medical devices and equipment
     suggests that large companies will be better able to compete in these
     industries and that it is an attractive time for smaller companies to
     consider strategic alternatives. For example, the Cardiometrics Board
     believes it would be beneficial for Cardiometrics to be part of a larger
     organization with greater market strength and market recognition and offer
     its products as part of a broader range of products and devices for
     assessing and treating coronary artery and other vascular disease.
 
          Complementary Technologies. The Cardiometrics Board believes the
     respective technology platforms of Cardiometrics and EndoSonics are
     complementary in nature, as demonstrated by other medical applications
     combining anatomical and functional testing, such as echocardiography (the
     use of ultrasound energy to image the heart and assess its blood flow
     dynamics) and vascular stroke screening, and that the resulting
     opportunities to offer integrated cardiac catherization laboratory products
     combining anatomical imaging and functional flow and pressure measurements
     would be attractive.
 
          Incremental Sales Opportunities. The Merger provides the opportunity
     to achieve potential revenue synergies, including the ability to market
     Cardiometrics' products through EndoSonics' worldwide sales and marketing
     partnership with Cordis/Johnson & Johnson and to sell Cardiometrics
     products together with EndoSonics products on a bundled basis.
 
          Potential Expense Efficiencies. The Merger provides the opportunity
     for the combined entity to achieve potential cost synergies, through
     consolidation and integration of certain manufacturing, distribution, sales
     and administrative operations and functions.
 
          Product Diversification. The Cardiometrics Board believes the Merger
     affords Cardiometrics' stockholders an opportunity to reduce their exposure
     to the risks inherent in Cardiometrics' reliance on a limited number of
     products. In addition, the Merger affords Cardiometrics the opportunity to
     utilize the resources of the Combined Company to develop additional
     products for customers and to develop those products more rapidly.
 
          Increased Trading Liquidity. The Cardiometrics Board believes that the
     larger market capitalizations of EndoSonics and CVD compared to
     Cardiometrics and the corresponding increase in trading liquidity of the
     EndoSonics Common Stock compared to the Cardiometrics Common Stock should
     benefit the former Cardiometrics stockholders.
 
     Terms of the Reorganization Agreement. In the course of its deliberations
regarding the Merger, the Cardiometrics Board reviewed and considered the terms
and conditions of the Reorganization Agreement, including the following.
 
          Merger Consideration.  The Cardiometrics Board reviewed and considered
     each component of the Merger Consideration and the provisions for
     adjustments to the Merger Consideration. Because the Merger Consideration
     consists of the fixed EndoSonics Exchange Ratio and a fixed range of CVD
     Exchange Ratios, the Board reviewed and considered that the value of the
     Merger Consideration could have a range of values at the Effective Time
     based on the values of the EndoSonics Common Stock and CVD Common Stock at
     such time. The Cardiometrics Board determined that the Merger Consideration
     is fair to Cardiometrics' stockholders, even though the value of the Merger
     Consideration at the Effective Time could fluctuate above and below the
     value of the Merger Consideration on the date it approved the
     Reorganization Agreement, because it determined, among other reasons, that
     (i) there are a range of values at which the Merger Consideration is fair
     to Cardiometrics' stockholders and (ii) many of the factors that would tend
     to cause the value of the Merger Consideration to fluctuate (by causing the
     value of the Endosonics Common Stock and CVD Common Stock to fluctuate)
     would also cause the value of the Cardiometrics Common Stock to fluctuate.
     In determining that the Merger Consideration, consisting of the EndoSonics
     Exchange Ratio, the CVD Exchange Ratio and the Cash Consideration, was fair
     to Cardiometrics stockholders, the Cardiometrics Board relied, among other
     things, on (i) the
 
                                       57
<PAGE>   69
 
     opinion of Dillon Read rendered on January 26, 1997 that, as of such date,
     the merger consideration to have been received by holders of Cardiometrics
     Common Stock pursuant to the Merger before the Amendment, which original
     merger consideration was modified in certain respects by the Amendment, was
     fair, from a financial point of view, to the holders of Cardiometrics
     Common Stock (See "-- Fairness Opinion") and (ii) its determination that
     the Merger Consideration was more favorable to Cardiometrics stockholders
     than the original merger consideration. A key reason for this determination
     is that the value of the Merger Consideration was higher than the original
     merger consideration on January 24, 1997, the last trading day before
     announcement of the proposed Merger, on May 20, 1997, the date the
     Amendment was approved, and on average during the twenty trading day period
     immediately prior to the approval of the Amendment (April 23 through May
     20, 1997). The following table illustrates this increase in value:
 
<TABLE>
<CAPTION>
                   DATE            ORIGINAL MERGER CONSIDERATION     AMENDED MERGER CONSIDERATION
        -------------------------- -----------------------------     ----------------------------
        <S>                        <C>                               <C>
        January 24, 1997..........             $8.99                            $ 9.23
        May 20, 1997..............             $7.59                            $ 7.98
        Average April 23 through
          May 20, 1997............             $7.42                            $ 7.84
        Average January 24,
          through June 11, 1997...             $8.15                            $ 8.21
</TABLE>
 
          The Board also considered that cash represented a larger portion and
     CVD Common Stock represented a smaller portion of the Merger Consideration
     than of the original merger consideration. The Board believed that
     inclusion of CVD Common Stock as part of the Merger Consideration has
     tended to complicate the Merger, (i) because the value of the Merger
     Consideration fluctuates as a value of two separate securities, (ii)
     because CVD's business is less complementary to Cardiometrics' business
     than EndoSonics' business and therefore more difficult for Cardiometrics
     stockholders to assess and (iii) because CVD will not be part of the
     combined entity after the Merger and therefore will be unaffected by the
     contribution of Cardiometrics' business, personnel and technology to
     EndoSonics. The Board believed these concerns were decreased by reducing
     the portion of the Merger Consideration attributable to CVD Common Stock.
     In addition, the Board considered that increasing the cash portion of the
     Merger Consideration reduced fluctuations in the value of the Merger
     Consideration compared to the original merger consideration as a result of
     fluctuations in the value of EndoSonics and CVD Common Stock. In
     particular, the Board noted that the value of the Merger Consideration
     declined less in value below $8.00 per share than the original merger
     consideration as a result of declines in the value of EndoSonics or CVD
     Common Stock.
 
          Absence of a Termination Right.  The Cardiometrics Board considered
     that, as a result of the Amendment, Cardiometrics would have no right to
     terminate the Reorganization Agreement based on the value of the Merger
     Consideration (as determined based on the values of the EndoSonics Common
     Stock and CVD Common Stock included as part of the Merger Consideration).
 
          Cardiometrics Stockholder Vote. The Cardiometrics Board considered the
     opportunity of the Stockholders of Cardiometrics to vote on whether to
     approve the Merger.
 
          Provision for Alternative Proposals.  The Cardiometrics Board reviewed
     and considered the lack of any substantial impediments to the ability of
     the Cardiometrics Board to entertain alternative proposals for a business
     combination transaction, negotiate and give information to third parties
     and terminate the Reorganization Agreement in the event of an alternative
     proposal, if required by the Cardiometrics Board's fiduciary duties to
     Cardiometrics' stockholders (see "-- The Agreement and Plan of
     Reorganization -- Fees and Expenses; Termination Fee" and "-- Related
     Agreements -- Stock Option Agreement").
 
          Limited Closing Conditions.  The Cardiometrics Board reviewed and
     considered the limited conditions to the consummation of the Merger and the
     resulting likelihood of consummation of the Merger.
 
     Results of Due Diligence Analyses. As part of its evaluation of the Merger,
the Cardiometrics Board also reviewed and considered the following information.
 
                                       58
<PAGE>   70
 
          Companies' Performance and Prospects.  The Cardiometrics Board
     reviewed and considered the financial performance and condition, business
     operations and prospects of each of EndoSonics, CVD and Cardiometrics.
 
          Historical Trading Prices.  The Cardiometrics Board reviewed and
     considered the historical trading prices for Cardiometrics Common Stock,
     EndoSonics Common Stock and CVD Common Stock.
 
          Stock Price Premium.  The Cardiometrics Board reviewed and considered
     the fact that the consideration per share of Cardiometrics Common Stock
     that may be received under the Reorganization Agreement represented a
     substantial premium over historical trading prices of Cardiometrics Common
     Stock. For example, the value of the Merger Consideration, based on closing
     prices of EndoSonics Common Stock and CVD Common Stock on the last trading
     day prior to announcement of the Reorganization Agreement (January 24,
     1997), represented a 41.0% premium to the closing price of Cardiometrics
     Common Stock on January 24, 1997, a 63.5% premium to the 30-day average
     closing price for Cardiometrics Common Stock ending on January 24, 1997 and
     an 84.8% premium to the six-month average closing price for Cardiometrics
     Common Stock ending on January 24, 1997.
 
          Strategic Alternatives.  The Cardiometrics Board reviewed and
     considered Cardiometrics' management's assessment of possible strategic
     alternatives, including remaining a separate company, entering joint
     ventures or distribution arrangements, and merging with a third party,
     including as part of its exploration of strategic alternatives, extensive
     discussions with Cardiometrics' Japanese distributor concerning a possible
     acquisition.
 
          Assessment of Alternative Acquisition Prospects.  The Cardiometrics
     Board reviewed and considered the fact that, although Cardiometrics did not
     currently conduct a formal auction, the Cardiometrics Board believed that a
     more attractive offer would not be available based on past attempts to sell
     Cardiometrics and difficulties in obtaining a U.S. distribution partner for
     Cardiometrics and that pursuing such an offer would significantly increase
     risks to Cardiometrics' ongoing business operations and may have caused
     EndoSonics to cease negotiations or withdraw its offer.
 
          Dillon Read Fairness Opinion.  The Cardiometrics Board reviewed and
     considered the oral opinion of Dillon Read delivered on January 26, 1997
     (which was subsequently confirmed in writing) that, as of such date, the
     consideration to have been received by holders of Cardiometrics Common
     Stock pursuant to the Merger before the Amendment, which was modified in
     certain respects by the Amendment, was fair to the holders of Cardiometrics
     Common Stock from a financial point of view (see "-- Fairness Opinion of
     Dillon Read").
 
     Potential Negative Factors. In addition to the risks described above in
"Risk Factors -- Risks Associated with the Merger," the Cardiometrics Board also
reviewed and considered the following potentially negative material factors in
its deliberations concerning the Merger.
 
          Loss of Control.  The Cardiometrics Board reviewed and considered its
     loss of control over the future operations of Cardiometrics following the
     Merger and the resulting potential for disruption in operations arising
     from the change in control of Cardiometrics.
 
          Failure to Achieve Potential Benefits.  The Cardiometrics Board
     reviewed and considered the risk that the benefits sought to be achieved in
     the Merger may be delayed or may not be achieved.
 
          Employee Uncertainty.  The Cardiometrics Board reviewed and considered
     the potential disruption of Cardiometrics' business that might result from
     employee uncertainty and lack of focus following announcement of the Merger
     and during the combination of operations.
 
          Failure to Consummate Merger.  The Cardiometrics Board reviewed and
     considered the possibility that the Merger would not be consummated and the
     effect of public announcement of the Merger on Cardiometrics' sales and
     operating results and its ability to attract and retain employees and the
     effects on the Company, its operations and its public stock price from the
     public announcement of a termination of the Reorganization Agreement.
 
                                       59
<PAGE>   71
 
          Merger Expenses.  The Cardiometrics Board reviewed and considered the
     substantial expenses to be incurred in connection with the Merger.
 
          Departure of Key Personnel.  The Cardiometrics Board reviewed and
     considered the risk that key personnel may not remain employed by the
     Combined Company.
 
          Absence of a Termination Right.  The Cardiometrics Board considered
     that, as a result of the Amendment, Cardiometrics would have no right to
     terminate the Reorganization Agreement regardless of the value of the
     Merger Consideration (as determined based on the value of the Endosonics
     and Cardiometrics Common Stock included as part of the Merger
     Consideration).
 
     In view of the wide variety of factors considered by the Cardiometrics
Board, it did not find it practicable to quantify, or otherwise attempt to
assign relative weights to the specific factors considered in making its
determination. However, after taking into account all factors set forth above,
the Cardiometrics Board determined that the Merger was fair to, and in the best
interests of, Cardiometrics and its stockholders. THE CARDIOMETRICS BOARD
RECOMMENDS THAT CARDIOMETRICS STOCKHOLDERS VOTE FOR ADOPTION OF THE
REORGANIZATION AGREEMENT.
 
OPERATIONS FOLLOWING THE MERGER
 
     Following the Merger, Cardiometrics will continue its operations as a
wholly-owned subsidiary of EndoSonics. Upon consummation of the Merger, the
members of Cardiometrics' Board of Directors will be Reinhard J. Warnking and
Donald D. Huffman. The membership of the Board of Directors of EndoSonics will
remain unchanged as a result of the Merger, except that EndoSonics expects that
Dr. Nassi will join the EndoSonics Board of Directors. The stockholders of
Cardiometrics will become stockholders of EndoSonics and stockholders of CVD,
and their rights as stockholders will be governed by EndoSonics' and CVD's
respective Certificates of Incorporation and Bylaws and the laws of the State of
Delaware. See "Comparison of Rights of Stockholders of EndoSonics, CVD and
Cardiometrics."
 
FAIRNESS OPINION OF DILLON READ
 
     On January 26, 1997, the Board of Directors of Cardiometrics received
Dillon Read's opinion dated January 26, 1997 which provided that, as of such
date, the consideration to have been received by holders of Cardiometrics Common
Stock pursuant to the terms of the Agreement and Plan of Reorganization, as it
existed prior to the Amendment, was fair to Cardiometrics' common stockholders
from a financial point of view. A copy of Dillon Read's written opinion is
attached as Appendix C hereto and should be read in its entirety for a
description of the procedures followed, matters considered, assumptions made and
methods employed by Dillon Read. Cardiometrics stockholders are advised that the
Dillon Read Opinion does not speak to the Merger Consideration, which the
Cardiometrics Board considered to be more favorable than the original merger
consideration.
 
     In arriving at its opinion, Dillon Read, among other things:
 
          (i) reviewed certain publicly available business and historical
     financial information relating to Cardiometrics, EndoSonics and CVD;
 
          (ii) reviewed certain management estimates and company financial
     forecasts prepared by the managements of Cardiometrics and EndoSonics;
 
          (iii) reviewed certain publicly available analyst financial forecasts
     relating to Cardiometrics, EndoSonics and CVD;
 
          (iv) reviewed certain financial information and other data provided to
     Dillon Read by Cardiometrics that was not publicly available relating to
     the business and prospects of Cardiometrics;
 
          (v) reviewed certain financial information and other data provided to
     Dillon Read by EndoSonics that was not publicly available relating to the
     business and prospects of EndoSonics;
 
          (vi) conducted discussions with members of the senior managements of
     Cardiometrics, EndoSonics and CVD with respect to the operations, financial
     condition, history and prospects of each company, including a review of
     publicly available analyst financial forecasts;
 
                                       60
<PAGE>   72
 
          (vii) reviewed publicly available financial and stock market data with
     respect to certain other companies in lines of business Dillon Read
     believed to be generally comparable to those of Cardiometrics, EndoSonics
     and CVD;
 
          (viii) considered the pro forma effects of the Merger (as it was then
     proposed) on EndoSonics' financial statements and reviewed certain
     estimates of synergies prepared by the management of Cardiometrics;
 
          (ix) reviewed the historical market prices and trading volumes of the
     Cardiometrics Common Stock, the EndoSonics Common Stock and the CVD Common
     Stock;
 
          (x) compared the financial terms of the Merger (as it was then
     proposed) with the financial terms of certain other transactions which
     Dillon Read believed to be generally comparable to the Merger (as it was
     then proposed);
 
          (xi) reviewed the Agreement and Plan of Reorganization, as it existed
     prior to the Amendment; and
 
          (xii) conducted such other financial studies, analyses and
     investigations, and considered such other information as Dillon Read deemed
     necessary or appropriate.
 
     In connection with its review, Dillon Read did not assume any
responsibility for independent verification of any of the foregoing information
and, with Cardiometrics' consent, relied on such information as being complete
and accurate in all material respects. In addition, Dillon Read has not made any
evaluation or appraisal of any of the assets or liabilities (contingent or
otherwise) of Cardiometrics, EndoSonics and CVD. With respect to the financial
forecasts referred to above, Dillon Read assumed, with Cardiometrics' consent,
that the Cardiometrics and EndoSonics company financial forecasts and the then
most recent publicly available CVD analyst financial forecast were prepared
reasonably on a basis reflecting the best currently available estimates and
judgments of the respective managements as to the future financial performance
of their respective companies. Dillon Read also understood that Cardiometrics,
from time to time, conducted discussions relating to a potential transaction
with parties other than EndoSonics, however, Dillon Read was not authorized to,
nor did it, solicit other third party offers for either all or a portion of
Cardiometrics. Dillon Read's opinion is based on economic, monetary, and market
conditions existing on January 26, 1997. No other limits were placed on Dillon
Read with respect to the investigations made or procedures followed by Dillon
Read in rendering its opinion. In rendering its opinion, Dillon Read was not
asked to, and did not determine, a range of values for the Merger Consideration
at which it was fair to stockholders of Cardiometrics. In arriving at its
opinion, Dillon Read reviewed, among other things, the Reorganization Agreement,
including the EndoSonics Exchange Ratio and CVD Exchange Ratio (as they were
then proposed).
 
     In arriving at its opinion, Dillon Read did not assign any particular
weight to any analysis or factor considered by it, but rather made qualitative
judgments based on its experience in rendering such opinions and on then
existing economic, monetary and market conditions as to the significance and
relevance of each analysis and factor. Accordingly, Dillon Read believes that
its analyses must be considered as a whole and that selecting portions of its
analyses and the factors considered, without considering all analyses and
factors, could create a misleading or incomplete view of the processes
underlying such analyses and its opinion. In its analyses, Dillon Read made
numerous assumptions with respect to industry performance, general business and
economic conditions and other matters, many of which are beyond Cardiometrics',
EndoSonics' or CVD's control. Any estimates contained in Dillon Read's analyses
are not necessarily indicative of actual values or predictive of future results
or values, which may be significantly more or less favorable than as set forth
therein. In addition, analyses relating to the value of a business or securities
do not purport to be appraisals or to reflect the actual prices at which
businesses or securities might be sold.
 
     The following summarizes the material quantitative analyses relating to
Cardiometrics, EndoSonics and CVD performed by Dillon Read in arriving at the
opinion dated January 26, 1997 presented to the Cardiometrics Board of
Directors. As used in the following discussion, the Original Merger
Consideration refers to the merger consideration as it existed prior to the
Amendment and as set forth under "Cardiometrics Valuation Review -- Summary of
Comparable Companies Analysis."

  Cardiometrics Valuation Review
 
     Summary of Stock Price Performance and Market Expectations Since Initial
Public Offering.  Using publicly available information, Dillon Read reviewed the
stock price performance of a group of six interventional cardiology device
companies in addition to Cardiometrics, which completed initial public offerings
since the beginning of 1995, from the date of their respective initial public
offerings through January 24, 1997. The companies included InStent, Inc.,
Perclose Inc., Endovascular Technologies Inc., Arterial Vascular Engineering
Inc., Novoste Corporation, and Cardiovascular Dynamics, Inc. The group of
companies including Cardiometrics, and excluding InStent, Inc. because of its
sale to Medtronic Inc. effective July 1, 1996, had an average stock price
appreciation from their respective initial public offering dates through January
24, 1997 of 7.5%, whereas the Standard & Poor's 500 Index appreciated 21.4% on
average, and the Standard & Poor's Medical Device Index appreciated 17.4% on
average. From the date of Cardiometrics' initial public offering on November 11,
1995 through January 26, 1997, Cardiometrics' Common Stock price per share
declined 29.2%, whereas the Standard & Poor's 500 Index appreciated 30.5%, and
the Standard & Poor's Medical Device Index appreciated 23.0%.
 
     Dillon Read also noted that there had been a significant change in the
financial forecasts for Cardiometrics from the time of Cardiometrics' initial
public offering in November 1995 to January 1997. From the November 1995
publicly available analyst financial forecasts to the January 22, 1997
Cardiometrics company financial forecasts, projected net sales and earnings per
share for fiscal 1997 declined significantly, primarily as a result of
Cardiometrics' decision to accelerate spending on major clinical outcome studies
and the failure of its AccuTrac guide wire to obtain market acceptance.
 
     Historical Trading Analysis.  Dillon Read reviewed the recent stock market
performance of Cardiometrics Common Stock. The analysis indicated that between
July 24, 1996 and January 24, 1997 the average price of a share of Cardiometrics
Common Stock was $4.89 based on the average of the closing prices for the six
months ended January 24, 1997. Dillon Read also noted that between December 12,
1996 and January 24, 1997 the average price of a share of Cardiometrics Common
Stock was $5.49 based on the average of the closing prices for the 30 trading
days ended January 24, 1997. Between January 20, 1997 and January 24, 1997 the
average price of a share of Cardiometrics Common Stock was $6.43 based on the
average of the closing prices for the week ended January 24, 1997.
 
     Summary of Comparable Companies Analysis.  Using publicly available
information, Dillon Read reviewed the stock prices and market multiples of
common stocks of the following companies in the interventional cardiology
business: Arrow International, Arterial Vascular Engineering, Boston Scientific
Corporation, CardioVascular Dynamics, Inc., C.R. Bard, Inc., EndoSonics
Corporation, Merit Medical, and Spectranetics. Dillon Read believes these
companies are engaged in lines of business that are generally comparable to
those of Cardiometrics.
 
     Dillon Read considered the one-year and three-year historical compounded
annual net sales growth rates for these comparable companies and calculated a
range of values. One-year historical net sales growth was 39.6% at the median,
and ranged from 6.9% to 222.2%. Three-year historical compounded annual net
sales growth was 37.9% at the median, and ranged from 6.2% to 336.6%. Dillon
Read noted that for Cardiometrics, one-year historical net sales growth was
23.4% and three-year historical compounded annual net sales growth was 14.3%.
 
     Dillon Read determined the equity market value and derived an "enterprise
value" (defined as equity market value adjusted by adding total debt and
subtracting cash and cash equivalents) for each of these comparable companies,
and calculated a range of such enterprise values as a multiple of the latest 12
months net sales, gross profit, and earnings before interest and taxes, and as a
multiple of calendar year 1996, 1997, 1998 and 1999 net sales using publicly
available analyst financial forecasts. Enterprise value as a multiple of the
latest 12 months net sales at the median was 4.9x and ranged from 1.6x to 9.2x
for these comparable companies. Enterprise value as a multiple of the latest 12
months gross profit at the median was 7.9x and ranged from 3.3x to 20.7x.
Enterprise value as a multiple of the latest 12 months earnings before interest
and taxes at the median was 14.7x and ranged from 9.0x to 29.8x. Enterprise
value as a multiple of calendar year 1996 net sales at the median was 3.9x and
ranged from 1.6x to 8.4x. Enterprise value as a multiple of calendar year 1997
net sales at the median was 3.0x
 
                                       62
<PAGE>   74
 
and ranged from 1.3x to 6.8x. Enterprise value as a multiple of calendar year
1998 net sales at the median was 2.2x and ranged from 1.3x to 5.6x. Enterprise
value as a multiple of calendar year 1999 net sales at the median was 1.2x and
ranged from 0.8x to 2.3x.
 
     Dillon Read also considered the equity value for each of these comparable
companies, and calculated a range of equity values as a multiple of projected
1997 and 1998 earnings per share estimates based on publicly available analyst
financial forecasts. Equity value to 1997 earnings per share estimates for these
comparable companies at the median was 19.6x, and ranged from 13.4x to 65.6x.
Equity value to 1998 earnings per share estimates at the median was 25.0x, and
ranged from 12.1x to 42.7x. Dillon Read determined the projected five-year
compounded annual earnings per share growth rate and the 1997 and 1998 projected
price-earnings ratios to the projected five-year earnings per share growth
estimates for these comparable companies using publicly available analyst
financial forecasts. Projected five-year compounded annual earnings per share
growth was 25.0% at the median, and ranged from 11.5% to 50.0%. The projected
price-earnings ratio to the projected five-year earnings per share growth
estimate in 1997 was 1.22x at the median, and ranged from 0.79x to 2.19x for
these comparable companies, and in 1998 was 1.00x at the median, and ranged from
0.51x to 1.05x.
 
     Based on (i) the closing price of EndoSonics Common Stock on January 24,
1997 of $13.125 and an Exchange Ratio of 0.35, (ii) the closing price of CVD
Common Stock on January 24, 1997 of $12.00 and an Exchange Ratio of 0.20, and
(iii) $2.00 in cash, the per share Merger Consideration (the "Original Merger
Consideration") of $8.99 per share of Cardiometrics Common Stock, Dillon Read
noted that the Original Merger Consideration was 4.1x latest 12 months net
sales, 6.8x latest 12 months gross profit, and not meaningful for latest 12
months earnings before interest and taxes because Cardiometrics' earnings before
interest and taxes was negative. The Original Merger Consideration was 3.9x
calendar year 1996 net sales, 2.7x calendar year 1997 net sales, 1.9x calendar
year 1998 net sales, and 1.3x calendar year 1999 net sales. The Original Merger
Consideration per share of Cardiometrics Common Stock as a multiple of 1997
earnings per share was not meaningful as Cardiometrics' earnings per share were
projected to be zero, and was 18.0x 1998 earnings per share. Cardiometrics'
projected five-year compounded annual earnings per share growth was 15.0%.
Cardiometrics' projected price-earnings ratio to its projected five-year
earnings per share growth estimate was not meaningful in 1997 as Cardiometrics
earnings are projected to be zero, and was 1.20x in 1998. Dillon Read believes
that the calculated multiples supported Dillon Read's view that the Original
Merger Consideration to have been received by Cardiometrics stockholders was
fair, from a financial point of view, to such stockholders, because the ratios
described above were within the range of selected public comparable multiples.
 
     Summary of Comparable Mergers and Acquisitions Analysis.  Using publicly
available information, Dillon Read reviewed the purchase prices and multiples
paid in selected mergers and acquisitions involving cardiology related companies
which Dillon Read deemed relevant in evaluating the Merger. Dillon Read reviewed
the acquisition of Corvita by Pfizer, Inc.; the acquisition of InStent, Inc. by
Medtronic, Inc.; the acquisition of Daig Corporation by St. Jude Medical, Inc.;
the acquisition of Cordis Corporation by Johnson & Johnson; the acquisition of
EP Technologies by Boston Scientific Corporation; the acquisition of Heart
Technology, Inc. by Boston Scientific Corporation; the acquisition of Medrad,
Inc. by Schering AG; the acquisition of MedChem Products by C.R. Bard, Inc.; the
acquisition of SciMed Life Systems, Inc. by Boston Scientific Corporation; the
acquisition of NAMIC USA Corporation by Pfizer, Inc.; the acquisition of
Cardiovascular Imaging Systems, Inc. by Boston Scientific; and the acquisition
of Webster Laboratories, Inc. by Cordis Corporation.
 
     Dillon Read considered multiples of the enterprise value of the
transactions (consideration offered for the equity plus the debt assumed less
the cash and equivalents of the acquired company) to the net sales and the
earnings before interest and taxes of the acquired businesses for the 12 months
preceding the acquisition announcement, to the net sales of the acquired
businesses in the first fiscal year following the announcement, to the net sales
of the acquired businesses in the second fiscal year following the announcement,
and to the net sales of the acquired businesses in the third fiscal year
following the announcement. The multiples of net sales for the 12 months
preceding the acquisition announcement at the median were 5.1x and ranged from
2.1x to 11.1x. The multiples of earnings before
 
                                       63
<PAGE>   75
 
interest and taxes for the 12 months preceding the acquisition announcement at
the median were 21.9x and ranged from 13.2x to 40.6x. The multiples of net sales
for the first fiscal year following the announcement at the median were 6.2x and
ranged from 1.9x to 80.9x. The multiples of net sales for the second fiscal year
following the announcement at the median were 3.8x and ranged from 1.7x to
17.0x. The multiples of net sales for the third fiscal year following the
announcement at the median were 2.8x and ranged from 1.0x to 7.6x. Dillon Read
also considered multiples of equity value of the transaction to net income for
the first fiscal year following the announcement at the median which was 26.8x
and ranged from 16.8x to 49.1x, and multiples of equity value of the transaction
to net income for the second fiscal year following the announcement at the
median which was 28.5x and ranged from 13.2x to 37.7x.
 
     The Original Merger Consideration per share of Cardiometrics Common Stock
represented 4.1x net sales for the 12 months preceding the acquisition
announcement, an earnings before interest and taxes for the 12 months preceding
the acquisition announcement multiple that was not meaningful because
Cardiometrics' earnings before interest and taxes was negative, 3.9x fiscal year
1996 net sales, 2.7x fiscal year 1997 net sales, and 1.9x fiscal year 1998 net
sales. Dillon Read also noted that the Original Merger Consideration resulted in
an equity value to net income for the 1997 fiscal year multiple that was not
meaningful because Cardiometrics' net income is projected to be zero in 1997,
and resulted in an equity value to net income for the 1998 fiscal year multiple
that was 18.0x. Dillon Read believes that the calculated multiples supported
Dillon Read's view that the Original Merger Consideration to have been received
by Cardiometrics stockholders was fair, from a financial point of view, to such
stockholders, because the ratios described above were within the range of
selected public comparable multiples.
 
     Dillon Read also considered the premiums paid for the acquired businesses
to their respective market closing prices per share one day and thirty days
prior to acquisition announcement relative to the premium of the Original Merger
Consideration of $8.99 per share of Cardiometrics Common Stock to the market
closing prices per share of Cardiometrics Common Stock prior to the announcement
of the transaction. The premium paid for the acquired businesses compared to the
market closing price one day prior to announcement at the median was 18.9%, and
ranged from (1.9%) to 45.1%, and compared to the market closing price thirty
days prior to announcement at the median was 37.2%, and ranged from 2.2% to
76.2%. The premium offered in the Original Merger Consideration for
Cardiometrics Common Stock compared to the market closing price one day prior to
the announcement of the transaction was 41.1%, and compared to the market
closing price thirty days prior to the announcement of the transaction was
71.3%.
 
     Discounted Cash Flow Analysis for Cardiometrics.  Dillon Read performed a
discounted cash flow analysis of Cardiometrics using a set of underlying
operating assumptions which were based upon the company financial forecast
provided by Cardiometrics management. Utilizing the Cardiometrics financial
forecast, Dillon Read calculated the theoretical discounted present value of
equity for Cardiometrics by adding together the present value of (i) the future
stream of unlevered free cash flow through the year 2000, (ii) the future value
of Cardiometrics at the end of the year 2000 (the "Terminal Value"), (iii) the
cash at year-end 1996 less total debt and (iv) the exercise proceeds from
outstanding stock options. The Terminal Value was calculated based on multiples
of earnings before interest and taxes for 2000 ranging from 8.0x to 12.0x. The
cash flow streams and terminal values were then discounted to present values
using a range of discount rates from 30.0% to 40.0%. The terminal multiples and
discount rates were chosen based on several assumptions regarding factors such
as inflation rates, interest rates, the inherent risk in Cardiometrics'
business, products and technology as well as the medical technology industry as
a whole, and the cost of capital of Cardiometrics.
 
     The theoretical equity value of Cardiometrics based on the set of
projections produced a range of value per share of Cardiometrics Common Stock of
$6.96 to $11.35, with a median value of $8.89. Dillon Read believes that the
discounted cash flow analysis supported Dillon Read's view that the Original
Merger Consideration to have been received by Cardiometrics stockholders was
fair, from a financial point of view, to such stockholders, because the
consideration valued at the time of Dillon Read's opinion was within the range
of present values of Cardiometrics' future cash flows.

  EndoSonics Valuation Review
 
     Historical Trading Analysis.  Dillon Read reviewed the recent stock market
performance of EndoSonics Common Stock. The analysis indicated that between July
24, 1996 and January 24, 1997 the average price of a share of EndoSonics Common
Stock was $13.33 based on the average of the closing prices for the six months
ended January 24, 1997. Dillon Read also noted that between December 12, 1996
and January 24, 1997 the average price of a share of EndoSonics Common Stock was
$13.92 based on the average of the closing prices for the 30 trading days ended
January 24, 1997. Between January 20, 1997 and January 24, 1997 the average
price of a share of EndoSonics Common Stock was $13.90 based on the average of
the closing prices for the week ended January 24, 1997.
 
     Summary of Comparable Companies Analysis.  Using publicly available
information, Dillon Read reviewed stock prices and market multiples of common
stocks of the following companies: Arrow International Inc., Arterial Vascular
Engineering Inc., Boston Scientific Corporation, Cardiovascular Dynamics, Inc.,
C.R. Bard, Inc., Merit Medical Systems Inc., and Spectranetics Corporation which
Dillon Read believes are engaged in lines of business that are generally
comparable to those of Endosonics Corporation.
 
     Dillon Read considered the one-year and three-year historical compounded
annual net sales growth rates, and the closing stock price on January 24, 1997
as a percent of the 52-week high for these comparable companies and calculated a
range of values. One-year historical net sales growth was 27.8% at the median,
and ranged from 6.9% to 222.2%. Three-year historical compounded annual net
sales growth was 29.4% at the median, and ranged from 6.2% to 336.6%. The
closing stock price on January 24, 1997 as a percent of the 52-week high was
68.3% at the median, and ranged from 27.0% to 96.2%. Dillon Read noted that for
EndoSonics, one-year historical net sales growth was 131.6%, three-year
historical compounded annual net sales growth was 69.5%, and the closing stock
price on January 24, 1997 as a percent of the 52-week high was 67.3%.
 
     Dillon Read determined the equity market value and derived an "enterprise
value" (defined as equity market value adjusted by adding total debt and
subtracting cash and cash equivalents) for each of these comparable companies,
and calculated a range of such enterprise values as a multiple of the latest 12
months net sales, gross profit, and earnings before interest and taxes, and as a
multiple of calendar year 1996, 1997, 1998 and 1999 net sales. Enterprise value
as a multiple of the latest 12 months net sales at the median was 4.4x and
ranged from 1.6x to 9.2x for these comparable companies. Enterprise value as a
multiple of the latest 12 months gross profit at the median was 6.6x and ranged
from 3.3x to 17.1x. Enterprise value as a multiple of the latest 12 months
earnings before interest and taxes at the median was 14.7x and ranged from 9.0x
to 29.8x. Enterprise value as a multiple of calendar year 1996 net sales at the
median was 4.1x and ranged from 1.6x to 8.4x. Enterprise value as a multiple of
calendar year 1997 net sales at the median was 3.0x and ranged from 1.3x to
6.8x. Enterprise value as a multiple of calendar year 1998 net sales at the
median was 2.6x and ranged from 1.3x to 5.6x. Enterprise value as a multiple of
calendar year 1999 net sales at the median was 1.3x and ranged from 0.8x to
2.3x.
 
     Dillon Read also considered the equity value for each of these comparable
companies, and calculated a range of equity values as a multiple of projected
1997 and 1998 earnings per share estimates based on publicly available analyst
financial forecasts. Equity value to 1997 earnings per share estimates for these
comparable companies at the median was 19.5x, and ranged from 13.4x to 31.6x.
Equity value to 1998 earnings per share estimates at the median was 20.1x, and
ranged from 12.3x to 42.7x. Dillon Read reviewed the projected five-year
compounded annual earnings per share growth rate, and the 1997 and 1998
projected price-earnings ratios to the projected five-year earnings per share
growth estimates for these comparable companies using publicly available analyst
financial forecasts. Projected five-year compounded annual earnings per share
growth was 24.5% at the median, and ranged from 11.5% to 50.0%. The projected
price-earnings ratio to the projected five-year earnings per share growth
estimate in 1997 was 1.00x at the median, and ranged from 0.79x to 1.27x for
these comparable companies, and in 1998 was 1.00x at the median, and ranged from
0.51x to 1.05x.
 
     Dillon Read noted that the closing price of EndoSonics Common Stock on
January 24, 1997 of $13.125 was 5.4x latest 12 months net sales, 20.7x latest 12
months gross profit, and not meaningful for
 
                                       65
<PAGE>   77
 
latest 12 months earnings before interest and taxes because EndoSonics' earnings
before interest and taxes was negative. The closing price of EndoSonics Common
Stock was 3.7x calendar year 1996 net sales, 2.7x calendar year 1997 net sales,
1.9x calendar year 1998 net sales, and 1.2x calendar year 1999 net sales.
EndoSonics' equity value as a multiple of 1997 earnings per share was 65.6x, and
equity value to 1998 earnings per share was 25.2x. EndoSonics' projected
five-year compounded annual earnings per share growth was 30.0%, projected
price-earnings ratio to its projected five-year earnings per share growth
estimate was 2.19x in 1997, and was 0.84x in 1998. Dillon Read believes that the
calculated multiples supported Dillon Read's view that the Original Merger
Consideration to have been received by Cardiometrics stockholders was fair, from
a financial point of view, to such stockholders, because taken as a whole, the
EndoSonics ratios described above were within the range of selected public
comparable multiples.
 
     Discounted Cash Flow Analysis for EndoSonics.  Dillon Read performed a
discounted cash flow analysis of EndoSonics using a set of underlying operating
assumptions which were based upon the company financial forecast provided by
EndoSonics management. Utilizing the EndoSonics financial forecast, Dillon Read
calculated the theoretical discounted present value of equity for EndoSonics by
adding together the present value of (i) the future stream of unlevered free
cash flow through the year 2000, (ii) the future value of EndoSonics at the end
of the year 2000 (the "Terminal Value"), (iii) the cash at year-end 1996 less
total debt, and (iv) the equity market value of the CVD Common Stock owned by
EndoSonics. The Terminal Value was calculated based on multiples of earnings
before interest and taxes for 2000 ranging from 11.0x to 15.0x. The cash flow
streams and terminal values were then discounted to present values using a range
of discount rates from 20.0% to 30.0%. The terminal multiples and discount rates
were chosen based on several assumptions regarding factors such as inflation
rates, interest rates, the inherent risk in EndoSonics' business, products and
technology as well as the medical technology industry as a whole, and the cost
of capital of EndoSonics.
 
     The theoretical equity value of EndoSonics based on the set of projections
produced a range of value per share of EndoSonics Common Stock of $12.08 to
$17.90, with a median value of $14.55. Dillon Read believes that the discounted
cash flow analysis supported Dillon Read's view that the Original Merger
Consideration to have been received by Cardiometrics stockholders was fair, from
a financial point of view, to such stockholders, because the EndoSonics Common
Stock value at the time of Dillon Read's opinion was within the range of present
values of EndoSonics' future cash flows.
 
     Pro Forma Merger Analysis.  Dillon Read considered the pro forma financial
impact of the Merger on EndoSonics' 1997, 1998 and 1999 earnings per share
estimates utilizing the company financial forecasts for EndoSonics and
Cardiometrics. Dillon Read calculated a range of values, expressed as the
percentage accretion or dilution in EndoSonics' earnings per share, that
incorporated Cardiometrics' management estimates of the potential synergies in
the combination of EndoSonics and Cardiometrics, and EndoSonics' management
estimates of goodwill amortization due to the potential write down of acquired
in-process research and development. The calculated range of values assumed
potential annual synergies from $0.0 to $1.5 million in 1997, $0.0 to $5.3
million in 1998, and $0.0 to $11.6 million in 1999, and a potential writedown of
acquired in-process research and development from 0% to 75% of total goodwill or
$0 to $34 million. Given this range of factors, the impact on EndoSonics' pro
forma earnings per share was dilutive in 1997, accretive in 1998 and accretive
in 1999.
 
  CVD Valuation Review
 
     Historical Trading Analysis.  Dillon Read reviewed the recent stock market
performance of CVD Common Stock. The analysis indicated that between July 24,
1996 and January 24, 1997 the average price of a share of CVD Common Stock was
$13.61 based on the average of the closing prices for the six months ended
January 24, 1997. Dillon Read also noted that between December 12, 1996 and
January 24, 1997 the average price of a share of EndoSonics Common Stock was
$12.11 based on the average of the closing prices for the 30 trading days ended
January 24, 1997. Between January 20, 1997 and January 24, 1997 the average
price of a share of CVD Common Stock was $10.30 based on the average of the
closing prices for the week ended January 24, 1997.

     Dillon Read considered the one-year and three-year historical compounded
annual net sales growth rates, and the closing stock price on January 24, 1997
as a percent of the 52-week high for these comparable companies and calculated a
range of values. One-year historical net sales growth was 27.8% at the median,
and ranged from 6.9% to 222.2%. Three-year historical compounded annual net
sales growth was 29.4% at the median, and ranged from 6.2% to 336.6%. The
closing stock price on January 24, 1997 as a percent of the 52-week high was
69.3% at the median, and ranged from 28.8% to 95.1%. Dillon Read noted that for
CVD, one-year historical net sales growth was 71.7%, three-year historical
compounded annual net sales growth was 470.6%, and the closing stock price on
January 24, 1997 as a percent of the 52-week high was 68.6%.
 
     Dillon Read determined the equity market value and derived an "enterprise
value" (defined as equity market value adjusted by adding total debt and
subtracting cash and cash equivalents) for each of these comparable companies,
and calculated a range of such enterprise values as a multiple of the latest 12
months net sales, gross profit, and earnings before interest and taxes, and as a
multiple of calendar year 1996, 1997, 1998 and 1999 net sales. Enterprise value
as a multiple of the latest 12 months net sales at the median was 4.4x and
ranged from 1.6x to 9.2x for these comparable companies. Enterprise value as a
multiple of the latest 12 months gross profit at the median was 6.6x and ranged
from 3.3x to 20.7x. Enterprise value as a multiple of the latest 12 months
earnings before interest and taxes at the median was 14.7x and ranged from 9.0x
to 29.8x. Enterprise value as a multiple of calendar year 1996 net sales at the
median was 3.7x and ranged from 1.6x to 8.4x. Enterprise value as a multiple of
calendar year 1997 net sales at the median was 2.9x and ranged from 1.3x to
6.8x. Enterprise value as a multiple of calendar year 1998 net sales at the
median was 2.6x and ranged from 1.4x to 5.6x. Enterprise value as a multiple of
calendar year 1999 net sales at the median was 1.3x and ranged from 1.2x to
2.3x.
 
     Dillon Read also considered the equity value for each of these comparable
companies, and calculated a range of equity values as a multiple of projected
1997 and 1998 earnings per share estimates based on publicly available analyst
financial forecasts. Equity value to 1997 earnings per share estimates for these
comparable companies at the median was 19.6x, and ranged from 13.4x to 65.6x.
Equity value to 1998 earnings per share estimates at the median was 20.1x, and
ranged from 12.1x to 42.7x. Dillon Read reviewed the projected five-year
compounded annual earnings per share growth rate, and the 1997 and 1998
projected price-earnings ratios to the projected five-year earnings per share
growth estimates for those comparable companies using publicly available analyst
financial forecasts. Projected five-year compounded annual earnings per share
growth was 24.5% at the median, and ranged from 11.5% to 30.0%. The projected
price-earnings ratio to the projected five-year earnings per share growth
estimate in 1997 was 1.09x at the median, and ranged from 0.79x to 2.19x for
these comparable companies, and in 1998 was 0.91x at the median, and ranged from
0.51x to 1.05x.
 
     Dillon Read noted that the closing price of CVD Common Stock on January 24,
1997 of $12.00 was 7.9x latest 12 months net sales, 17.1x latest 12 months gross
profit, and not meaningful for latest 12 months earnings before interest and
taxes because CVD's earnings before interest and taxes was negative. The closing
price of CVD Common Stock was 6.7x calendar year 1996 net sales, 3.0x calendar
year 1997 net sales, 1.3x calendar year 1998 net sales, and 0.8x calendar year
1999 net sales. Dillon Read also noted that CVD's equity value as a multiple of
1997 earnings per share was not meaningful because CVD's earnings per share were
negative, and equity value to 1998 earnings per share was 26.7x. CVD's projected
five-year compounded annual earnings per share growth was 50.0%, projected
price-earnings ratio to its projected five-year earnings per share growth
estimate was not meaningful in 1997 because CVD earnings per share were
negative, and was 0.53x in 1998. Dillon Read believes that the calculated
multiples supported Dillon Read's view that the Original Merger Consideration to
have
 
                                       67
<PAGE>   79
 
been received by Cardiometrics stockholders was fair, from a financial point of
view, to such stockholders, because taken as a whole, the CVD ratios described
above were within the range of selected public comparable multiples.
 
     Discounted Cash Flow Analysis for CVD.  Dillon Read performed a discounted
cash flow analysis of CVD using a set of underlying operating assumptions which
were based upon the most recent publicly available analyst financial forecast.
Utilizing the analyst financial forecast for CVD, Dillon Read calculated the
theoretical discounted present value of equity for CVD by adding together the
present value of (i) the future stream of unlevered free cash flow through the
year 1999, (ii) the future value of CVD at the end of the year 1999 (the
"Terminal Value") and, (iii) the cash at year-end 1996 less total debt. The
Terminal Value was calculated based on multiples of earnings before interest,
taxes for 1999 ranging from 11.0x to 15.0x. The cash flow streams and terminal
values were then discounted to present values using a range of discount rates
from 25.0% to 35.0%. The terminal multiples and discount rates were chosen based
on several assumptions regarding factors such as inflation rates, interest
rates, the inherent risk in CVD's business, products and technology as well as
the medical technology industry as a whole, and the cost of capital of CVD.
 
     The theoretical equity value of CVD based on the set of projections
produced a range of value per share of CVD Common Stock of $9.98 to $14.38, with
a median value of $11.96. Dillon Read believes that the discounted cash flow
analysis supported Dillon Read's view that the Original Merger Consideration to
have been received by Cardiometrics stockholders was fair, from a financial
point of view, to such stockholders, because the CVD Common Stock value at the
time of Dillon Read's opinion was within the range of present values of CVD's
future cash flows.
 
     Dillon Read believes that its analyses must be considered as a whole and
that selecting portions of its analyses and other factors considered by it,
without considering all factors and analyses, could create a misleading view of
the processes underlying its opinion. Dillon Read did not quantify the effect of
each factor upon its opinion. Dillon Read made numerous assumptions with respect
to industry performance, general business and economic conditions and other
matters, many of which are beyond Cardiometrics' and Dillon Read's control. Any
estimates contained in Dillon Read's analyses are not necessarily indicative of
actual values, which may be significantly more or less favorable than as set
forth therein. Estimates of the financial value of companies do not purport to
be appraisals or necessarily reflect the prices at which companies actually may
be sold. Because such estimates inherently are subject to uncertainty, neither
Cardiometrics, EndoSonics, Dillon Read nor any other person assumes
responsibility for their accuracy. In rendering its opinion, Dillon Read
expressed no view as to the range of values at which the EndoSonics Common
Stock, or the CVD Common Stock, may trade following the consummation of the
Merger, nor did Dillon Read make any recommendations to the Cardiometrics
stockholders with respect to how such holders should vote on the Merger, or to
the advisability of disposing of or retaining such EndoSonics Common Stock and
CVD Common Stock following the Merger.
 
     Dillon Read is an internationally recognized investment banking firm which,
as a part of its investment banking business, regularly is engaged in the
evaluation of businesses and their securities in connection with mergers and
acquisitions, negotiated underwritings, competitive bids, secondary
distributions of listed and unlisted securities, private placements and
valuations for estate, corporate and other purposes. Dillon Read was the lead
manager for the initial public offering of Cardiometrics Common Stock on
November 11, 1995 prior to its engagement in connection with the Merger. In the
ordinary course of its business, Dillon Read has traded Cardiometrics Common
Stock for its own account and for the accounts of customers and has traded
EndoSonics Common Stock for the accounts of customers and, accordingly, may at
any time hold a long or short position in such securities.
 
     Pursuant to an engagement letter, dated December 9, 1996, between
Cardiometrics and Dillon Read, Cardiometrics has paid Dillon Read (i) $50,000
upon execution of the December 9, 1996 engagement letter and (ii) $300,000 for
services rendered in connection with the preparation of its fairness opinion and
has further agreed to pay Dillon Read 1.4% of the aggregate merger consideration
upon the consummation of the Merger, less the fees previously paid pursuant to
the December 9, 1996 engagement letter. Cardiometrics has also agreed to
reimburse Dillon Read for the expenses reasonably
 
                                       68
<PAGE>   80
 
incurred by it in connection with its engagement (including reasonable counsel
fees) and to indemnify Dillon Read and its officers, directors, employees,
agents and controlling persons against certain expenses, losses, claims, damages
or liabilities in connection with its services, including those arising under
the federal securities laws.
 
RELATED AGREEMENTS
 
  Voting Agreements
 
     In connection with the Merger, certain stockholders of Cardiometrics have
entered into voting agreements, as subsequently amended, forms of which are
attached as Appendix D hereto (the "Voting Agreements"). The terms of the Voting
Agreements provide (i) that such stockholders will not transfer (except as may
be specifically required by court order), sell, exchange, pledge (except in
connection with a bona fide loan transaction) or otherwise dispose of or
encumber their shares of Cardiometrics Common Stock beneficially owned by them,
or certain new shares of such stock they may acquire, at any time prior to the
Expiration Date (as defined below), and (ii) that such stockholders will vote
certain shares of Cardiometrics Common Stock beneficially owned by them in favor
of the approval of the Reorganization Agreement and approval of the Merger and
against any proposal for any recapitalization, merger, sale of assets or other
business combination (other than the Merger) between Cardiometrics and any
person or entity other than EndoSonics or any other action or agreement that
would result in a breach of any covenant, representation or warranty or any
other obligation or agreement of Cardiometrics under the Reorganization
Agreement or which could result in any of the conditions to Cardiometrics'
obligations under the Reorganization Agreement not being fulfilled. The Voting
Agreements are accompanied by irrevocable proxies (the "Proxies") whereby such
stockholders provide to the members of the Board of Directors of EndoSonics the
right to vote certain of the shares beneficially owned by them on the proposals
relating to the Reorganization Agreement and the Merger at the Cardiometrics
Meeting and any competing proposal at a Cardiometrics stockholder meeting.
Holders of approximately 5.7% of the shares of Cardiometrics Common Stock
entitled to vote at the Cardiometrics Meeting have entered into the Voting
Agreements and Proxies. The Voting Agreements and Proxies shall terminate on the
Expiration Date. As used herein, the term "Expiration Date" shall mean the
earlier to occur of (i) such date and time as the Merger shall become effective
in accordance with the terms and provisions of the Reorganization Agreement and
(ii) six months after the date of termination of the Reorganization Agreement.
 
  Non-Competition Agreements
 
     EndoSonics and Merger Sub have entered into non-competition agreements with
Menahem Nassi and Robert Y. Newell, IV (each, an "Employee", and collectively,
the "Employees"), a form of which is attached as Appendix E hereto. During the
period commencing on the Closing Date and ending on the earlier of Employee's
cessation of employment with EndoSonics and 12 months after the Closing Date,
the Employee will not (i) participate or engage in the design, development,
manufacture, production, marketing, sale or servicing of any product, or the
provision of any service, that directly relates to the functional testing in the
cardiac catheterization laboratory utilizing flow and/or pressure sensor based
angioplasty guide wires and corresponding instrumentation (the "Business") in
the United States or in Canada, (ii) induce or attempt to induce any person who
at the time of such inducement is an employee of Cardiometrics or EndoSonics to
perform work or services for any other person or entity other than Cardiometrics
or EndoSonics or (iii) permit Employee's name to be used in connection with a
business or endeavor that competes with the Business, either in whole or in
part, anywhere in the United States or Canada; provided that the non-competition
clause will not apply if Employee's employment is terminated by EndoSonics or
Cardiometrics other than as a result of Employee's voluntary resignation or for
"Cause." There can be no assurance that such non-competition and
non-solicitation provisions will be enforceable under California law.
 
  Stock Option Agreement
 
     Pursuant to the Stock Option Agreement, a copy of which is attached as
Appendix F to this Proxy Statement/Prospectus and is incorporated herein by
reference, EndoSonics has the right (the "Stock Option"), under certain
circumstances, to acquire up to 1,379,717 shares of authorized but unissued
 
                                       69
<PAGE>   81
 
shares of Cardiometrics Common Stock (the "Cardiometrics Shares") (constituting
approximately 19.9% of the outstanding shares of Cardiometrics Common Stock at a
price of $9.00 per share (the "Exercise Price"), payable in cash, or, at
EndoSonics' option, Cardiometrics will loan EndoSonics the Exercise Price (less
the par value of the shares issued upon exercise, such par value to be paid in
cash), pursuant to an interest-free one-year term loan. Pursuant to the terms of
the Stock Option Agreement, the type and number of securities subject to the
Stock Option, and the price per share, shall be adjusted in the event of any
change in Cardiometrics Common Stock by reason of certain events, including
stock dividends, splitups, mergers (other than the Merger), recapitalizations,
combinations, exchange of shares or the like.
 
     The Stock Option Agreement is exercisable by EndoSonics, in whole or in
part, at any time or from time to time after any event occurs which would permit
EndoSonics to terminate the Reorganization Agreement and recover the $3,500,000
termination fee described in "The Merger and Related Transactions -- Amendments,
Termination and Waivers." The Stock Option will terminate upon the earlier of:
(i) the Effective Time; (ii) the termination of the Reorganization Agreement
pursuant to its terms (other than a termination in connection with which
EndoSonics is entitled to the payment of the $3,500,000 termination fee); or
(iii) 180 days following any termination of the Reorganization Agreement in
connection with which EndoSonics is entitled to the payment of the $3,500,000
termination fee (or, if at the expiration of such 180-day period, the Stock
Option cannot be exercised by reason of any applicable judgment, decree, order,
law or regulation, ten (10) business days after such impediment to exercise
shall have been removed or shall have become final and not subject to appeal),
but in no event later than March 31, 1998. Notwithstanding the foregoing, (x)
the Stock Option may not be exercised if EndoSonics is in material breach of any
of its representations, warranties, covenants or agreements contained in the
Stock Option Agreement or in the Reorganization Agreement and (y) in the event
EndoSonics receives more than the Exercise Price multiplied by the number of
Cardiometrics Shares purchased by EndoSonics pursuant to the Stock Option, in
connection with sales or other dispositions of the Cardiometrics Shares, all
proceeds in excess of such amount shall be remitted to Cardiometrics.
 
     Under the terms of the Stock Option Agreement, at any time during which the
Stock Option is exercisable (the "Repurchase Period"), EndoSonics has the right
to require Cardiometrics (or any successor entity thereof) to repurchase from
EndoSonics all or any part of the Stock Option, and Cardiometrics (or any
successor entity thereof) has the right to require EndoSonics to sell to
Cardiometrics (or such successor entity) all or any part of the Stock Option;
however, upon any such sale by EndoSonics, EndoSonics will remit to
Cardiometrics any proceeds otherwise payable to EndoSonics from any such
disposition of the Stock Option. Also, at any time prior to March 31, 1998,
EndoSonics has the right to require Cardiometrics (or any successor entity
thereof) to repurchase from EndoSonics, and Cardiometrics (or any successor
entity thereof) has the right to require EndoSonics to sell to Cardiometrics (or
such successor entity), all or any part of the Cardiometrics Shares purchased by
EndoSonics pursuant to the Stock Option; however, any proceeds to EndoSonics
from such repurchase or sale of the Cardiometrics Shares which are in excess of
the exercise price paid by EndoSonics to exercise the Stock Option will be
remitted to Cardiometrics. Thus the Stock Option has no financial value, but
would allow EndoSonics to vote the Cardiometrics Shares if the Stock Option were
exercised.
 
     Notwithstanding the foregoing, the right of Cardiometrics or any successor
thereof to require EndoSonics to sell the Stock Option or the Cardiometrics
Shares shall not be exercisable unless Cardiometrics shall have consummated the
transaction provided by a Takeover Proposal or Cardiometrics' stockholders shall
have transferred their shares of Cardiometrics Common Stock pursuant to a tender
or exchange offer or other Takeover Proposal.

THE AGREEMENT AND PLAN OF REORGANIZATION
 
     The following is a summary of the material provisions of the Reorganization
Agreement not summarized elsewhere in this Proxy Statement/Prospectus. The
Reorganization Agreement is attached as Appendix A to this Proxy
Statement/Prospectus and is incorporated herein by reference. This summary is
qualified in its entirety by reference to the Reorganization Agreement.
 
  Representations and Warranties
 
     The Reorganization Agreement contains various representations and
warranties of the parties, including representations by EndoSonics,
Cardiometrics and Merger Sub as to their organization capitalization, and
corporate authority, the existence of certain liabilities and the absence of
certain material undisclosed liabilities and changes in their businesses. Such
representations and warranties will not survive consummation of the Merger.
 
  Covenants of EndoSonics and Cardiometrics; Conduct Prior to Merger
 
     Under the terms of the Reorganization Agreement, and for the period from
the date of the Reorganization Agreement and continuing until the earlier of the
termination of the Reorganization Agreement or the Effective Time, each of
Cardiometrics and EndoSonics has agreed to carry on its and its subsidiaries'
business in the ordinary course in substantially the same manner as conducted
prior to execution of the Reorganization Agreement, and to use all reasonable
efforts consistent with past practice to preserve its and its subsidiaries'
present business organizations. Each of Cardiometrics and EndoSonics has also
agreed to promptly notify the other of any event or occurrence not in the
ordinary course of its or its subsidiaries' business or which could have a
material adverse effect on it and its subsidiaries. In addition, each of
EndoSonics and Cardiometrics has agreed that it will not do, cause or permit any
of the following without the prior written consent of the other: (a) cause or
permit any amendments to its Certificate of Incorporation or Bylaws; (b) declare
or pay any dividends on or make any other distributions in respect of any of its
capital stock, or split, combine or reclassify any of its capital stock or issue
or authorize the issuance of any other securities in respect of, in lieu of or
in substitution for shares of its capital stock, or repurchase or otherwise
acquire any shares of its capital stock except from former employees, directors
and consultants in connection with any termination of service to it or its
subsidiaries; (c) accelerate, amend or change the period of exercisability or
vesting of options, warrants or other rights or authorize cash payments in
exchange for any options or other similar rights or (d) take any of the actions
described in (a) through (c) above. EndoSonics has also agreed to use reasonable
efforts to prevent CVD from doing any of the actions listed in (a) through (c)
of the preceding sentence.
 
  Conduct of Cardiometrics Business
 
     Moreover, under the terms of the Reorganization Agreement, Cardiometrics
has agreed that, during the period from the date of the Reorganization Agreement
and continuing until the earlier of the termination of the Reorganization
Agreement or the Effective Time, it will not, among other things, do, cause or
permit any of the following without the prior written consent of EndoSonics
which consent shall not be unreasonably withheld: (a) enter into any material
contract or material commitment, or violate, amend or otherwise modify or waive
any of the terms of any of contracts required to be filed as an exhibit to its
public filings other than in the ordinary course of business consistent with
past practice, but in no event shall such contract, commitment, amendment,
modification or waiver be in excess of $100,000; (b) issue, deliver or sell any
shares of its capital stock or securities convertible into, or subscriptions,
rights, warrants or options to acquire, or other agreements or commitments
obligating it to issue any such shares or other convertible securities, other
than the issuance of shares of its Common Stock pursuant to the exercise of
stock options or warrants outstanding as of the date of the Reorganization
Agreement with specific exceptions for stock option grants under its stock
option plans and repurchases; (c) transfer to any person or entity any rights to
its intellectual property other than in the ordinary course of business; (d)
enter into or amend any agreements pursuant to which any other party is granted
exclusive rights with respect to any of its products or technology; (e) sell,
lease, license or otherwise dispose of or encumber any of its properties or
assets which are material to its business except in the ordinary course of
business; (f) incur any indebtedness for borrowed money or guarantee
 
                                       71
<PAGE>   83
 
any such indebtedness or issue or sell any debt securities or guarantee any debt
securities of others; (g) enter into any operating lease in excess of an
aggregate of $50,000; (h) pay, discharge or satisfy in an amount in excess of
$25,000 in any one case or $100,000 in the aggregate, any claim, liability or
obligation other than the payment, discharge or satisfaction of liabilities
reflected or reserved against in Cardiometrics' financial statements or incurred
in the ordinary course of business; (i) make any material capital expenditures,
material capital additions or material capital improvements except in the
ordinary course of business; (j) materially reduce the amount of any material
insurance coverage; (k) adopt or amend any employee benefit or stock purchase or
option plan, or hire any new director level or officer level employee, pay any
special bonus or special remuneration to any employee or director, or increase
the salaries or wage rates of its employees except in the ordinary course of
business or for changes pursuant to pre-existing employment agreements or
changes in position; (l) grant any severance or termination pay to any director,
officer or other employee except for payments made pursuant to standard written
agreements or in the ordinary course of business; (m) commence a lawsuit other
than (x) for the routine collection of bills, (y) in such cases where it in good
faith determines that failure to commence suit would result in the material
impairment of a valuable aspect of its business, provided that it consults with
EndoSonics prior to the filing of such a suit, or (z) for a breach of the
Reorganization Agreement; (n) acquire or agree to acquire by merging or
consolidating with, or by purchasing a substantial portion of the assets of, any
business or other entity, or otherwise acquire or agree to acquire any assets
which are material to its business, or acquire or agree to acquire any equity
securities of any corporation or other entity; (o) other than in the ordinary
course of business, make or change any material election in respect of taxes,
adopt or change any accounting method in respect of taxes, file any material tax
return or any amendment to a material tax return, enter into any closing
agreement, settle any claim or assessment in respect of taxes, or consent to any
extension or waiver of the limitation period applicable to any claim or
assessment in respect of taxes; (p) revalue any of its assets other than in the
ordinary course of business; or (q) take any of the actions described in (a)
through (p) above.
 
  No Solicitation of Transactions
 
     Cardiometrics has further agreed that it will not, directly or indirectly,
(i) take any action to solicit, initiate or encourage any Takeover Proposal
(defined below) or (ii) subject to the terms of the immediately following
sentence, engage in negotiations with, or disclose any nonpublic information
relating to Cardiometrics to, or afford access to the properties, books or
records of Cardiometrics to, any person that has advised Cardiometrics that it
may be considering making, or that has made, a Takeover Proposal; provided,
nothing contained in the Reorganization Agreement shall prohibit Cardiometrics'
Board of Directors from taking and disclosing to Cardiometrics' stockholders a
position with respect to a tender offer pursuant to Rules 14d-9 and 14e-2
promulgated under the Exchange Act. Notwithstanding the immediately preceding
sentence, if an unsolicited Takeover Proposal, or an unsolicited written
expression of interest that can reasonably be expected to lead to a Takeover
Proposal, shall be received by the Cardiometrics Board, then, to the extent the
Cardiometrics Board believes in good faith (after consultation with its
financial advisor) that such Takeover Proposal would, if consummated, result in
a transaction more favorable to Cardiometrics' stockholders from a financial
point of view than the transaction contemplated by the Reorganization Agreement
(any such more favorable Takeover Proposal being referred to herein as a
"Superior Proposal") and the Cardiometrics Board determines in good faith after
consultation with outside legal counsel that it is necessary for the
Cardiometrics Board to comply with its fiduciary duties to stockholders under
applicable law, Cardiometrics and its officers, directors, employees, investment
bankers, financial advisors, attorneys, accountants and other representatives
retained by it may furnish in connection therewith information and take such
other actions as are consistent with the fiduciary obligations of the
Cardiometrics Board, and such actions shall not be considered a breach of the
Reorganization Agreement, provided that in each such event Cardiometrics
notifies EndoSonics of such determination by the Cardiometrics Board and
provides EndoSonics with a true and complete copy of the Superior Proposal
received from such third party, if the Superior Proposal is in writing, or a
complete written summary thereof, if it is not in writing, and provides
EndoSonics with all documents containing or referring to non-public information
 
                                       72
<PAGE>   84
 
of Cardiometrics that are supplied to such third party; provided, further, that
(A) the Cardiometrics Board has determined, with the advice of Cardiometrics'
investment bankers, that such third party is capable of making a Superior
Proposal upon satisfactory completion of such third party's review of the
information supplied by Cardiometrics, (B) the third party has made a written
expression of interest that can be reasonably be expected to lead to a Superior
Proposal, (C) Cardiometrics may not provide any non-public information to any
such third party if it has not prior to the date thereof provided such
information to EndoSonics or EndoSonics' representatives, and (D) Cardiometrics
provides such non-public information pursuant to a non-disclosure agreement at
least as restrictive as that certain non-disclosure agreement between EndoSonics
and Cardiometrics, dated January 3, 1997; provided, however, that Cardiometrics
shall not, and shall not permit any of its officers, directors, employees or
other representatives to agree to or endorse any Takeover Proposal unless
Cardiometrics shall have terminated the Reorganization Agreement pursuant to the
withdrawal or modification of the approval and recommendation of the
Reorganization Agreement by the Cardiometrics Board based on their fiduciary
duties to the Cardiometrics stockholders and paid to EndoSonics all amounts
payable to EndoSonics pursuant to the termination fees provision of the
Reorganization Agreement. As used herein, "Takeover Proposal" means any offer or
proposal for, or any indication of interest in, a merger or other business
combination involving Cardiometrics or the acquisition of any significant equity
interest in, or a significant portion of the assets of, Cardiometrics, other
than the transactions contemplated by the Reorganization Agreement.
 
  Conditions to the Merger
 
     Each party's respective obligation to effect the Merger is subject to,
among other things, the approval of the Reorganization Agreement and the Merger
by the requisite vote of the stockholders of Cardiometrics, the Commission
having declared the Proxy Statement/Prospectus and the CVD Registration
Statement effective, and the satisfaction at or prior to the Effective Time of
the additional following conditions: (a) the absence of any injunction, other
legal action or regulatory restraint preventing the consummation of the Merger
or rendering the consummation of the Merger illegal; (b) all approvals, waivers
and consents, if any, necessary for consummation of or in connection with the
Merger having been received; and (c) the filing with the Nasdaq National Market
of a Notification Form for Listing of Additional Shares with respect to the
shares of EndoSonics Common Stock issuable in connection with the Merger.
 
     The obligations of Cardiometrics to effect the Merger are subject to, among
other things, the satisfaction at or prior to the Effective Time of each of the
following conditions, unless waived in writing by Cardiometrics: (a) the
representations and warranties of EndoSonics and Merger Sub in the
Reorganization Agreement shall be true and correct in all material respects on
and as of the Effective Time; (b) EndoSonics and Merger Sub shall have performed
and complied in all material respects with all covenants, obligations and
conditions of the Reorganization Agreement required to be performed and complied
with by them as of the Effective Time; (c) Cardiometrics shall have received an
officer's certificate executed on behalf of EndoSonics;(d) there shall not have
occurred any material adverse change in the condition, properties, assets,
liabilities, business, operations or results of operations or prospects of
EndoSonics and its subsidiaries, taken as a whole; (e) Cardiometrics shall have
been furnished with evidence satisfactory to it of the consent or approval of
those persons whose consent or approval shall be required in connection with the
Merger under any material contract of EndoSonics or any of its subsidiaries or
otherwise; and (f) no temporary restraining order, preliminary or permanent
injunction or other legal or regulatory restraint provision limiting or
restricting EndoSonics' business following the Merger shall be in effect, nor
shall any proceeding brought by any governmental entity seeking the foregoing be
pending.
 
     The obligations of EndoSonics and Merger Sub to effect the Merger are
subject to, among other things, the satisfaction at or prior to the Effective
Time of each of the following conditions, unless waived in writing by
EndoSonics: (a) the representations and warranties of Cardiometrics in the
Reorganization Agreement shall be true and correct in all material respects on
and as of the Effective Time; (b) Cardiometrics shall have performed and
complied in all material respects with all covenants, obligations and conditions
of the Reorganization Agreement required to be performed and complied
 
                                       73
<PAGE>   85
 
with by it as of the Effective Time; (c) EndoSonics shall have received an
officer's certificate executed on behalf of Cardiometrics; (d) EndoSonics shall
have been furnished with evidence satisfactory to it of the consent or approval
of those persons whose consent or approval shall be required in connection with
the Merger under any material contract of Cardiometrics or otherwise; (e) no
temporary restraining order, preliminary or permanent injunction or other legal
or regulatory restraint provision limiting or restricting EndoSonics' conduct or
operation of the business of Cardiometrics following the Merger shall be in
effect, nor shall any proceeding brought by any governmental entity seeking the
foregoing be pending; and (f) there shall not have occurred any material adverse
change in the condition, properties, assets, liabilities, business, operations
or results of operations of Cardiometrics. To the extent any material conditions
are waived, Cardiometrics will resolicit stockholder approval prior to
consummation of the Merger.
 
  Closing
 
     As promptly as practicable after the satisfaction or waiver of the
conditions set forth in the Reorganization Agreement, Merger Sub and
Cardiometrics will file a certificate of merger with the Secretary of State of
Delaware. The Merger will become effective upon such filing. It is anticipated
that, assuming all conditions are met or waived, the Merger will occur and a
closing will be held on or before July 24, 1997.
 
  Amendments and Termination
 
     The Reorganization Agreement may be amended by the boards of directors of
the parties at any time by execution of an instrument in writing signed on
behalf of each of the parties thereto; provided that an amendment made
subsequent to adoption of the Reorganization Agreement by the stockholders of
Cardiometrics or Merger Sub shall not (i) alter or change the amount or kind of
consideration to be received on conversion of the Cardiometrics Common Stock,
(ii) alter or change any term of the Certificate of Incorporation of the
surviving corporation to be effected by the Merger, or (iii) alter or change any
of the terms and conditions of the Reorganization Agreement if such alteration
or change would adversely affect the holders of Cardiometrics Common Stock or
Merger Sub Common Stock.
 
     At any time prior to the Effective Time, the Reorganization Agreement may
be terminated (a) by mutual agreement of EndoSonics and Cardiometrics, (b) by
either EndoSonics or Cardiometrics if (i) without fault of the terminating
party, the closing of the Merger has not occurred on or before September 30,
1997, (ii) there is a breach by the other party of a representation, warranty or
obligation set forth in the Reorganization Agreement in any material respect and
such breach is not cured within ten (10) business days after receipt of written
notice from the other, (iii) a Trigger Event (as defined below) or Takeover
Proposal (as defined in "The Merger and Related Transactions -- The Agreement
and Plan of Reorganization -- No Solicitations of Transactions") shall have
occurred and the Cardiometrics Board of Directors in connection therewith
withdraws or modifies its approval and recommendation of the Reorganization
Agreement after determining that to cause Cardiometrics to proceed with the
Merger would not be consistent with the Cardiometrics Board's fiduciary duty to
the stockholders of Cardiometrics, (iv) there is a final, non-appealable order
of a court or other competent authority in effect preventing consummation of the
Merger or (v) the required approval of the stockholders of Cardiometrics is not
obtained at the Cardiometrics Meeting.
 
     The Reorganization Agreement may be terminated by EndoSonics prior to the
Effective Time if (i) Cardiometrics' Board of Directors withdraws or modifies
its recommendation of the Reorganization Agreement or the Merger in a manner
adverse to EndoSonics or shall have resolved to do any of the foregoing or (ii)
for any reason, Cardiometrics fails to call and hold the Cardiometrics Meeting
by September 30, 1997.
 
     For purposes of the Reorganization Agreement, a "Trigger Event" shall occur
if any person acquires securities representing 15% or more, or commences a
tender or exchange offer following the successful consummation of which the
offeror and its affiliates would beneficially own securities representing 20% or
more, of the voting power of Cardiometrics.

  Termination Fee
 
     In the event that (a) either EndoSonics or Cardiometrics terminates the
Reorganization Agreement following the occurrence of a Trigger Event or a
Takeover Proposal and the Cardiometrics Board has withdrawn or modified its
approval and recommendation of the Reorganization Agreement and the Merger after
determining that to cause Cardiometrics to proceed with the Merger would not be
consistent with their fiduciary duty to the stockholders of Cardiometrics, (b)
either EndoSonics or Cardiometrics terminates the Reorganization Agreement
following a failure of the stockholders of Cardiometrics to approve the
Reorganization Agreement at the Cardiometrics Meeting and, prior to the
Cardiometrics Meeting there shall have been (A) a Trigger Event with respect to
Cardiometrics or (B) a Takeover Proposal with respect to Cardiometrics which at
the time of the Cardiometrics Meeting shall not have been (x) rejected by
Cardiometrics or (y) withdrawn by the third party, (c) EndoSonics terminates the
Reorganization Agreement as a result of (i) a breach by Cardiometrics any of
Cardiometrics' representations, warranties or obligations under the
Reorganization Agreement in any material respects and such breach shall not have
been cured within ten business days of receipt by Cardiometrics of written
notice of such breach or (ii) Cardiometrics' failure to call and hold, for any
reason, the Cardiometrics Meeting by September 30, 1997, and prior thereto there
shall have been (A) a Trigger Event with respect to Cardiometrics or (B) a
Takeover Proposal with respect to Cardiometrics which shall not have been (x)
rejected by Cardiometrics and (y) withdrawn by the third party, or (d)
EndoSonics terminates the Reorganization Agreement as a result of the withdrawal
or modification by the Cardiometrics Board of its recommendation of the
Reorganization Agreement or the Merger in a manner adverse to EndoSonics or its
resolution to do any of the foregoing, then Cardiometrics shall promptly pay to
EndoSonics the sum of $3,500,000.
 
     In the event that EndoSonics terminates the Reorganization Agreement as a
result of (i) a breach by Cardiometrics any of Cardiometrics' representations,
warranties or obligations under the Reorganization Agreement in any material
respects and such breach shall not have been cured within ten business days of
receipt by Cardiometrics of written notice of such breach or (ii) Cardiometrics'
failure to call and hold, for any reason, the Cardiometrics Meeting by September
30, 1997, or (iii) a failure of the stockholders of Cardiometrics to approve the
Reorganization Agreement at the Cardiometrics Meeting, then, provided the Merger
Consideration at the time of the Cardiometrics Meeting is at least $9.00,
Cardiometrics shall promptly reimburse EndoSonics $1,500,000 for the
out-of-pocket costs and expenses incurred by EndoSonics in connection with the
Reorganization Agreement and the transactions contemplated thereby as
EndoSonics' sole remedy.
 
  Fees of Cardiometrics' Financial Advisor
 
     Pursuant to an engagement letter, dated December 9, 1996, between
Cardiometrics and Dillon Read, Cardiometrics has paid Dillon Read (i) $50,000
upon the execution of the December 9, 1996 engagement letter and (ii) $300,000
for services rendered in connection with the preparation of its fairness opinion
and has further agreed to pay Dillon Read 1.4% of the aggregate merger
consideration upon the consummation of the Merger, less the fees previously paid
pursuant to the December 9, 1996 engagement letter. Cardiometrics has also
agreed to reimburse Dillon Read for the expenses reasonably incurred by it in
connection with its engagement and to indemnify Dillon Read and its officers,
directors, employees, agents and controlling persons against certain liabilities
in connection with its services, including those arising under the federal
securities laws.
 
  Indemnification and Insurance
 
     The Reorganization Agreement provides that after the Effective Time,
EndoSonics will indemnify, defend and hold harmless the present and former
officers, directors, employees and agents of Cardiometrics (the "Indemnified
Parties") in respect of acts or omissions occurring on or prior to the Effective
Time to the full extent such corporation is permitted by law and the full extent
provided under Cardiometrics' Certificate of Incorporation and Bylaws or any
indemnification agreement with Cardiometrics officers and directors.
 
     The Reorganization Agreement also provides that, for four years after the
Effective Time, EndoSonics will either maintain at least $100,000,000 in cash,
marketable securities and unrestricted
 
                                       75
<PAGE>   87
 
lines of credit to be available to indemnify the Indemnified Parties or cause
Cardiometrics to use its best efforts to provide officers' and directors'
liability insurance in respect of acts or omissions occurring on or prior to the
Effective Time covering each such person covered on the date of the
Reorganization Agreement by Cardiometrics' officers' and directors' liability
insurance policy on terms substantially similar to those of such policy in
effect on the date of the Reorganization Agreement.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     In considering the recommendation of the Cardiometrics Board with respect
to the Merger, stockholders of Cardiometrics should be aware that certain
officers and directors of Cardiometrics have interests in the Merger, including
those referred to below, that are in addition to the interests of Cardiometrics'
stockholders generally. The Cardiometrics Board was aware of these interests and
considered them along with the other matters described in "The Cardiometrics
Meeting -- Board Recommendation" and "The Merger and Related
Transactions -- Reasons for the Merger."
 
     Cardiometrics Change in Control Severance Plan ("Severance Plan") provides
severance benefits for eligible employees of Cardiometrics, including the
officers of the Company, one of whom, Dr. Nassi, is also a member of the
Cardiometrics Board, upon an Involuntary Termination (as defined in the
Severance Plan) of employment within the 12-month period following a Change in
Control of Cardiometrics, which as defined in the Severance Plan includes the
Merger. Involuntary Termination is defined as either (i) dismissal without
cause, as further defined in the Severance Plan, (ii) resignation following
reduction in compensation, without employee consent, or relocation of employee's
place of employment, without employee consent, by more than 50 miles, or (iii)
in the case of officers, "directors" and managers immediately before the Change
in Control, resignation following a change in the employee's position that is
effected without the employee's consent and materially reduces his or her level
of responsibility or authority. The Severance Plan provides for cash severance
payments based on specified percentages of the involuntarily terminated
employee's annual base pay at the time of termination, with such percentages
ranging from 16 2/3% of annual base pay to 100% of annual base pay, payable in a
lump sum within 35 days of termination. If Dr. Nassi, Cardiometrics' President
and Chief Executive Officer, is involuntarily terminated, as defined in the
Severance Plan, during the 12-month period following the Effective Time, he
would receive 100% of his annual base pay. If any other executive officer of
Cardiometrics is involuntarily terminated, as defined in the Severance Plan,
during the 12-month period following the Effective Time, each such officer would
receive 50% of his or her annual base pay. 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.
 
     All of Cardiometrics' outstanding stock options and shares purchased under
options, including outstanding options and shares held by Cardiometrics'
officers and directors, will vest in full upon a Corporate Transaction (as such
term is defined in Cardiometrics' 1995 Incentive Plan). The Merger will
constitute a Corporate Transaction and, accordingly, all of Cardiometrics'
outstanding stock options and shares purchased under options, including those
held by Cardiometrics officers and directors, will vest in full at the Effective
Time.
 
     Cardiometrics and Dr. Nassi 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 Dr. Nassi will vest in full if Dr. Nassi
is terminated without cause (as defined in the Nassi Employment Agreement) or if
Cardiometrics is acquired before such options are fully vested. As of December
31, 1996, Dr. Nassi held unvested options for a total of 33,985 shares, all of
which will accelerate if Dr. Nassi is terminated without cause (as defined in
the Nassi Employment Agreement) or if Cardiometrics is acquired and,
accordingly, will become fully vested upon consummation of the Merger. The Nassi
Employment Agreement also provides for continuation of Dr. Nassi's salary and
benefits for a 12-month period in the event that his employment is terminated
without cause, provided that Dr. Nassi provides certain consulting services to
the Company and provided, further, that the severance payments will cease after
six months if Dr. Nassi obtains full-time employment. Under the terms of the
Severance Plan, Dr. Nassi cannot receive benefits under both his employment
agreement and the Severance Plan; instead, he
 
                                       76
<PAGE>   88
 
would receive benefits under the program that applied depending on the
circumstances of his employment termination or, if both apply, whichever would
provide greater benefits.
 
     EndoSonics and all officers and certain directors of Cardiometrics have
entered into a Voting Agreement and Irrevocable Proxy dated as January 26, 1997
(the "Voting Agreement") which provide, among other terms, that such officers
and directors will not transfer or otherwise dispose of any of the shares of
Cardiometrics Common Stock held by them. See "The Merger and Related
Transactions -- Related Agreements -- Voting Agreements." EndoSonics, Merger Sub
and Dr. Nassi entered into an Agreement dated as of January 26, 1997 pursuant to
which Dr. Nassi is authorized to sell a limited number of his shares
notwithstanding the Voting Agreement. Dr. Nassi is permitted to sell not more
than that number of shares which will generate proceeds sufficient to satisfy
Dr. Nassi's federal, state and local income tax liability and federal and state
alternative minimum tax liability incurred for the 1996 tax year in connection
with his exercise of a Cardiometrics stock option for 30,000 shares of
Cardiometrics Common Stock in 1996. As partial consideration for EndoSonics'
agreement to allow Dr. Nassi to sell a portion of his shares, Dr. Nassi has
agreed to exercise a portion of his outstanding Cardiometrics stock options
between January 26, 1997 and the date of the Cardiometrics Meeting to purchase
at least a number of shares of Cardiometrics Common Stock equal to the number of
shares he sells pursuant to the foregoing authorization. The Agreement further
provides that Dr. Nassi may sell an additional number of shares of Common Stock
sufficient to generate proceeds to satisfy any immediate tax liability arising
from the foregoing exercise. Dr. Nassi has not yet exercised his rights under
this Agreement and pursuant to Cardiometrics' Policy Against Insider Trading, as
an officer or director of Cardiometrics, Dr. Nassi is not permitted to sell
shares of Cardiometrics Common Stock between February 28 and three days
following Cardiometrics' public release of its earnings for the quarter ended
March 31.
 
     In order to facilitate the consummation of the Merger, the Cardiometrics
Board authorized the extension of loans to directors, officers and other
employees who agree to effect a net exercise of their outstanding Cardiometrics
Options prior to the Effective Time, in order to leave such persons in a tax
neutral position compared to having their Cardiometrics Options partially
assumed and partially converted pursuant to the Merger. Such net exercises would
facilitate the consummation of the Merger to the extent the resulting reduction
in the aggregate number of shares of Cardiometrics Common Stock issued or
issuable immediately prior to the Merger reduced the number of shares of
EndoSonics Common Stock issuable upon consummation of the Merger, therefore not
requiring the approval of EndoSonics' stockholders. However, as a result of
Endosonics' purchases of 300,000 shares of Cardiometrics Common Stock since the
execution of the Reorganization Agreement, EndoSonics does not require approval
of its stockholders to consummate the Merger. Therefore, with EndoSonics'
consent, Cardiometrics does not intend to grant loans or otherwise encourage net
exercises of Cardiometrics Options.
 
     Prior to the execution of the Reorganization Agreement, certain officers
and directors of EndoSonics held discussions with Dr. Nassi regarding his
joining the Board of Directors of EndoSonics following the Effective Time.
Immediately following the execution of the Reorganization Agreement, EndoSonics
publicly announced that Dr. Nassi is expected to join the EndoSonics Board.
Subsequently, EndoSonics entered into an agreement with Dr. Nassi dated as of
March 10, 1997, which is subject to the approval of the Merger by the
stockholders of Cardiometrics. This agreement provides that EndoSonics will make
a cash severance payment of $175,000 to Dr. Nassi and that Dr. Nassi may also
receive a discretionary bonus and stock option grant at the discretion of
Reinhard J. Warnking, President and Chief Executive Officer of EndoSonics, based
on the success of the Merger. Dr. Nassi has agreed to continue to serve as a
consultant to EndoSonics until approximately December 15, 1997 at the equivalent
of his current salary rate. The agreement also provides that Dr. Nassi will be
elected to the EndoSonics Board of Directors after the consummation of the
Merger.
 
     On March 14, 1997, EndoSonics entered into an employment agreement with
Michael J. Sorna, Cardiometrics' Vice President, International Sales and
Operations. The agreement provides that after the Merger closes Mr. Sorna will
become EndoSonics' Vice President, European Sales & Marketing based in The
Netherlands. EndoSonics has agreed to adjust Mr. Sorna's current base salary for
the
 
                                       77
<PAGE>   89
 
higher cost of living in the Netherlands, as well as reimburse him for
reasonable moving expenses. In addition, EndoSonics has agreed to provide Mr.
Sorna with a sign-on option package for 50,000 options subject to a four (4)
year vesting schedule. Mr. Sorna may also receive an additional 25,000 options
at the end of 1997 based on the achievement of certain milestones. Based on his
performance, Mr. Sorna may also receive a cash bonus of no less than $10,000, as
well as additional options. EndoSonics has also agreed to provide Mr. Sorna with
a benefits package and a company car.
 
     Several of Cardiometrics' other officers have also entered into agreements
with EndoSonics regarding their status after the consummation of the Merger.
Robert Y. Newell, IV entered into an agreement with EndoSonics pursuant to which
he has agreed to serve as a full time consultant to EndoSonics for the first
three months following the consummation of the Merger and as a half time
consultant for the three months after that. In addition, EndoSonics agreed to
pay $20,000 to Mr. Newell if certain goals are met and that Mr. Newell's
severance payment will be made within thirty-five days after the consummation of
the Merger. Stanley Levy, Jr. entered into an agreement with EndoSonics with the
following provisions: (i) EndoSonics will make Mr. Levy's severance payment on
July 21, 1997; (ii) Mr. Levy will be on vacation from July 21, 1997 to August 8,
1997; (iii) Mr. Levy will serve as a full time consultant to EndoSonics from
August 8, 1997 to December 31, 1997 and (iv) Mr. Levy will serve as a part time
consultant for all of 1998. Jeffery S. Frisbie has declined an offer to work for
EndoSonics after the consummation of the Merger. However, Mr. Frisbie has agreed
to continue working until the end of August 1997, at which time his severance
payment will be paid.
 
     The Reorganization Agreement provides that, after the Effective Time, the
surviving corporation shall, to the fullest extent permitted under the laws of
the State of Delaware or the Certificate of Incorporation or Bylaws of the
surviving corporation, indemnify and hold harmless each director of the
surviving corporation made, or threatened to be made, a party to an action or
proceeding, whether criminal, civil, administrative or investigative, by reason
of being a director of the corporation or a predecessor corporation. The Board
of Directors in its discretion shall have the power on behalf of the surviving
corporation to indemnify any person, other than a director, made a party to any
action, suit or proceeding by reason of the fact that he is or was an officer or
employee of the surviving corporation.
 
CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
     The following discussion summarizes the material federal income tax
consequences of (i) the exchange of shares of Cardiometrics Common Stock for
EndoSonics Common Stock, CVD Common Stock and cash pursuant to the Merger and
(ii) the assumption in part of Cardiometrics Options by EndoSonics and the
conversion of the balance into the right to receive CVD Common Stock and cash
pursuant to the Merger. This discussion is based on currently existing
provisions of the Internal Revenue Code of 1986, as amended (the "Code"),
existing and proposed Treasury Regulations thereunder and current administrative
rulings and court decisions, all of which are subject to change. Any such
change, which may or may not be retroactive, could alter the tax consequences to
EndoSonics, Cardiometrics or Cardiometrics' stockholders and optionholders, as
described herein.
 
     Cardiometrics stockholders and optionholders should be aware that this
discussion does not deal with all federal income tax considerations that may be
relevant to particular Cardiometrics stockholders or optionholders in light of
their particular circumstances, such as persons who are dealers in securities,
who are subject to the alternative minimum tax provisions of the Code, who are
foreign persons, who do not hold their Cardiometrics Common Stock as capital
assets, or who acquired their shares in connection with stock option or stock
purchase plans or in other compensatory transactions. In addition, the following
discussion does not address the tax consequences of the Merger under foreign,
state or local tax laws, the tax consequences of transactions effectuated prior
or subsequent to, or concurrently with, the Merger (whether or not any such
transactions are undertaken in connection with the Merger), including without
limitation any transaction in which shares of Cardiometrics Common Stock are
acquired or shares of EndoSonics Common Stock or CVD Common Stock are disposed
of. Accordingly, CARDIOMETRICS STOCKHOLDERS AND OPTIONHOLDERS ARE URGED TO
CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES OF THE
MERGER, INCLUDING THE APPLICABLE FEDERAL, STATE, LOCAL AND FOREIGN TAX
CONSEQUENCES TO THEM OF THE MERGER.
 
                                       78
<PAGE>   90
 
  Tax Consequences to Cardiometrics Stockholders
 
     The Merger will constitute a fully taxable transaction rather than a
tax-free reorganization. Each Cardiometrics stockholder will recognize gain or
loss upon the Merger based on the difference between (i) the sum of the cash,
the fair market value of the EndoSonics Common Stock and the fair market value
of the CVD Common Stock received by the Cardiometrics stockholder in the Merger
and (ii) such stockholder's tax basis in his or her shares of Cardiometrics
Common Stock exchanged in the Merger. Except in the case of certain stockholders
who have acquired their shares of Cardiometrics Common Stock through the
exercise of incentive stock options (as discussed below), such gain or loss will
be a capital gain or loss if the exchanged Cardiometrics Common Stock is a
capital asset in the hands of the Cardiometrics stockholder and will be
long-term capital gain or loss if such stockholder has held his or her shares of
Cardiometrics Common Stock for more than one year.
 
     Stockholders who acquired their shares of Cardiometrics Common Stock
through the exercise of incentive stock options under the federal tax laws will
trigger a disqualifying disposition of those shares when the shares are
exchanged for cash, CVD Common Stock and EndoSonics Common Stock in the Merger,
if the shares have not been held for more than two years from the grant date of
the incentive stock option and more than one year after the exercise date of the
incentive stock option for those shares. Upon such a disqualifying disposition,
the Cardiometrics stockholder will recognize ordinary income equal to the excess
of (i) the fair market value of the shares of Cardiometrics Common Stock at the
time the incentive stock option was exercised for those shares over (ii) the
aggregate exercise price paid for the shares. Any additional gain or any loss
recognized upon the exchange of those shares in the Merger will be a capital
gain or loss, which will be long-term if the shares of Cardiometrics Common
Stock have been held for more than one year. However, if the aggregate fair
market value of the EndoSonics Common Stock, CVD Common Stock and cash received
per share of Cardiometrics Common Stock in the Merger is less than the exercise
price paid per share of Cardiometrics Common Stock upon the exercise of the
incentive stock option, then the Cardiometrics stockholder will not recognize
any ordinary income upon the disqualifying disposition of those shares in the
Merger and will recognize a capital loss per share equal to the excess of such
exercise price per share over the Merger Consideration paid per share of
Cardiometrics Common Stock. The capital loss will be short-term unless the
shares of Cardiometrics Common Stock involved in the disqualifying disposition
have been held for more than one year.
 
  Tax Consequences to Holders of Cardiometrics Options
 
     Upon the conversion in part of each outstanding Cardiometrics Option into
the right to receive cash and CVD Common Stock in the Merger, the optionholder
will recognize ordinary income in the amount of the cash and the fair market
value of the CVD Common Stock received with respect to that option. Such income
will constitute wages subject to the Company's collection of applicable federal
and state income and employment withholding taxes.
 
     No income will be recognized for federal income tax purposes upon the
assumption of the Cardiometrics Options by EndoSonics. Each Cardiometrics Option
assumed by EndoSonics in the Merger will thereafter be subject to taxation in
accordance with the following provisions:
 
          INCENTIVE STOCK OPTION:  To the extent the assumed Cardiometrics
     Option continues as an incentive stock option after the Merger, the
     optionholder will not recognize any taxable income at the time that such
     option is exercised. However, the amount by which the fair market value (at
     the time of exercise) of the shares of EndoSonics Common Stock purchased
     under the assumed option exceeds the exercise price paid for those shares
     will constitute an adjustment to the optionholder's income for alternative
     minimum tax purposes. The optionholder will recognize taxable income in the
     year in which the purchased shares are sold or otherwise the subject of a
     taxable disposition. For federal income tax purposes, dispositions are
     divided into two categories: (i) qualifying and (ii) disqualifying. A
     qualifying disposition will occur if the sale or other disposition is made
     after the shares have been held for more than two years after the option
     grant date and more than one year after the option exercise date. Upon a
     qualifying disposition, the optionholder will recognize a long-term capital
     gain equal to the amount realized upon the sale or disposition of the
     shares less
 
                                       79
<PAGE>   91
 
     the exercise price paid for those shares. If either of the two holding
     periods is not satisfied, then a disqualifying disposition will result.
     Upon a disqualifying disposition of the purchased shares, the optionholder
     will recognize ordinary income in an amount equal to the excess of (i) the
     fair market value of those shares on the option exercise date over (ii) the
     exercise price paid for the shares. Any additional gain or any loss
     recognized upon the disqualifying disposition will be a capital gain or
     loss, which will be long-term if the shares are held for more than one year
     prior to such disposition.
 
          NON-STATUTORY STOCK OPTION:  To the extent the assumed Cardiometrics
     Option is a non-statutory option under the federal tax laws, the
     optionholder will, at the time such option is exercised, recognize ordinary
     income in an amount equal to the excess of (i) the fair market value of the
     purchased shares of EndoSonics Common Stock on the exercise date over (ii)
     the exercise price paid for those shares. Such income will constitute
     wages, and the optionholder will be required to satisfy the income and
     employment tax withholding liability attributable to those wages.
 
  Tax Consequences to EndoSonics and Cardiometrics
 
     Cardiometrics will not recognize taxable gain or loss as a result of the
Merger. EndoSonics will recognize taxable gain or loss upon the Merger based on
the difference between the fair market value of the CVD Common Stock transferred
in the Merger and EndoSonics' tax basis in such CVD Common Stock.
 
     Cardiometrics will be entitled to an income tax deduction with respect to
each disqualifying disposition of incentive stock option shares which occurs by
reason of the Merger. The amount of such deduction will be equal to the ordinary
income recognized by the optionholder in connection with the disqualifying
disposition.
 
     Cardiometrics will be entitled to an income tax deduction with respect to
the cash and the CVD Common Stock distributed with respect to each outstanding
Cardiometrics Option at the time of the Merger.
 
ACCOUNTING TREATMENT
 
     The Merger will be accounted for under the purchase method of accounting in
accordance with generally accepted accounting principles, whereby the purchase
price will be allocated based on the fair value of the assets acquired and
liabilities assumed. Such allocation will be made based upon valuations that
have not been finalized. It is anticipated that a significant portion of the
purchase price will be allocated to in-process research and development which
will result in a charge to EndoSonics' consolidated statement of operations of
approximately $41.1 million in the fiscal quarter in which the Merger closes.
The amount of the estimated charge is based on a preliminary valuation and the
actual amount could vary significantly upon completion of the final valuation.
 
     An effect of the purchase accounting will be to record developed technology
and other intangible assets which will result in amortization charges to the
operations of EndoSonics over the useful lives of such assets. The amount of
such charges are estimated at approximately $700,000 per fiscal year for
approximately eight years; however, actual charges could vary significantly in
the event the underlying assets are impaired or the related useful lives are
less than currently estimated. See "Unaudited Pro Forma Condensed Combined
Financial Data."
 
REGULATORY APPROVALS
 
     Neither Cardiometrics nor EndoSonics is aware of any regulatory approvals
necessary for the consummation of the Merger.
 
APPRAISAL RIGHTS
 
     Record holders of Cardiometrics Common Stock are entitled to appraisal
rights under Section 262 ("Section 262") of the Delaware General Corporations
Law (the "DGCL"). The following discussion represents a summary of the material
provisions of Section 262, and is qualified in its entirety by reference to the
full text of Section 262, which is reprinted in its entirety as Appendix B to
this Proxy Statement/Prospectus. A person having a beneficial interest in shares
of Cardiometrics Common Stock
 
                                       80

held of record in the name of another person, such as a broker or nominee, must
act promptly to cause the record holder to follow the steps summarized below
properly and in a timely manner to perfect the appraisal rights provided under
Section 262.
 
     Under Section 262, where a merger is to be submitted for approval at a
meeting of stockholders, as in the case of the Cardiometrics Meeting, not less
than 20 days prior to the meeting, a constituent corporation must notify each of
the holders of its stock for which appraisal rights are available that such
appraisal rights are available and include in each such notice a copy of Section
262. THIS PROXY STATEMENT/PROSPECTUS SHALL CONSTITUTE SUCH NOTICE TO THE RECORD
HOLDERS OF CARDIOMETRICS COMMON STOCK. ANY SUCH STOCKHOLDER WHO WISHES TO
EXERCISE SUCH APPRAISAL RIGHTS SHOULD REVIEW THE FOLLOWING DISCUSSION AND
APPENDIX B CAREFULLY, BECAUSE FAILURE TO TIMELY AND STRICTLY COMPLY WITH THE
PROCEDURES SPECIFIED MAY RESULT IN THE LOSS OF APPRAISAL RIGHTS UNDER THE DGCL.
 
     Under the DGCL, a record holder of shares of Cardiometrics Common Stock who
makes the demand described below with respect to such shares, who continuously
is the record holder of such shares through the Effective Time, who otherwise
complies with the statutory requirements set forth in Section 262 and who
neither votes in favor of approval of the Reorganization Agreement and the
Merger nor consents thereto in writing will be entitled to have their shares of
Cardiometrics Common Stock appraised by the Delaware Court of Chancery and to
receive payment of the "fair value" of such shares as described below. Such
holders are, in such circumstances, entitled to appraisal rights because they
hold stock of a constituent corporation to the Merger and are required by the
Reorganization Agreement to accept cash as a portion of the Merger
Consideration. Since holders of shares of Cardiometrics Common Stock wishing to
exercise appraisal rights must not vote in favor of approval of the
Reorganization Agreement and the Merger, such holders should not deliver
unmarked proxies (i.e., proxies without instructions) to Cardiometrics as such
proxies will be voted FOR such approval. See "The Cardiometrics
Meeting -- Voting of Proxies."
 
     A holder of share of Cardiometrics Common Stock wishing to exercise his
appraisal rights must deliver to the Secretary of Cardiometrics, before the vote
on the Reorganization Agreement at the Cardiometrics Meeting, a written demand
for appraisal of his shares of Cardiometrics Common Stock. Merely voting or
delivering a proxy directing a vote against approval of the Reorganization
Agreement and the Merger will not constitute a demand for appraisal. A written
demand is essential. Such written demand must reasonably inform Cardiometrics of
the identity of the holder and that such holder intends thereby to demand
appraisal of the holder's shares. All written demands for appraisal of
Cardiometrics Common Stock should be sent or delivered to Cardiometrics, Inc.,
645 Clyde Avenue, Mountain View, California 94043, Attn: Corporate Secretary. In
addition, a holder of shares of Cardiometrics Common Stock wishing to exercise
his appraisal rights must hold such shares of record on the date the written
demand for appraisal is made and must hold such shares continuously through the
Effective Time. Stockholders who hold their shares of Cardiometrics Common Stock
in brokerage accounts or other nominee forms and who wish to exercise appraisal
rights must take all necessary steps in order that a demand for appraisal is
made by the record holder of such shares and are urged to consult with their
brokers to determine the appropriate procedures for the making of a demand for
appraisal by the record holder.
 
     Within 10 days after the Effective Time, the Surviving Corporation must
send a notice as to the effectiveness of the Merger to each person who has
satisfied the appropriate provisions of Section 262 and who is entitled to
appraisal rights under Section 262. Within 120 days after the Effective Time,
any holder of record of shares of Cardiometrics Common Stock who has complied
with the requirements for exercise of appraisal rights will be entitled, upon
written request, to receive from the Surviving Corporation a statement setting
forth (i) the aggregate number of shares of Cardiometrics Common Stock not voted
in favor of the Reorganization Agreement and with respect to which demands for
appraisal have been received and (ii) the aggregate number of holders of such
shares. Any such statement must be mailed within 10 days after a written request
therefor has been received by the Surviving Corporation.
 
                                       81
<PAGE>   93
 
     Within 120 days after the Effective Time, but not thereafter, the Surviving
Corporation or any holder of shares of Cardiometrics Common Stock who has
complied with the foregoing procedures and who is entitled to appraisal rights
under Section 262 may file a petition in the Delaware Court of Chancery
demanding a determination of the "fair value" of such shares. The Surviving
Corporation is not under any obligation to file a petition with respect to the
appraisal of the "fair value" of the shares of Cardiometrics Common Stock and
neither EndoSonics nor Cardiometrics presently intends that the Surviving
Corporation file such a petition. Accordingly, it is the obligation of the
stockholders to initiate all necessary action to perfect their appraisal rights
within the time prescribed in Section 262. A holder of shares of Cardiometrics
Common Stock will fail to perfect, or effectively lose, his right to appraisal
if no petition for appraisal of shares of Cardiometrics Common Stock is filed
within 120 days after the Effective Time.
 
     If a petition for an appraisal is timely filed, after a hearing on such
petition, the Delaware Court of Chancery will determine the holders of shares of
Cardiometrics Common Stock entitled to appraisal rights and will appraise the
"fair value" of the shares of Cardiometrics Common Stock, exclusive of any
element of value arising from the accomplishment or expectation of the Merger.
Holders considering seeking appraisal should be aware that the "fair value" of
their shares of Cardiometrics Common Stock as determined under Section 262 could
be more than, the same as, or less than the value of the Merger Consideration
they would receive if they did not seek appraisal. The Delaware Supreme Court
has stated that "proof of value by any techniques or methods which are generally
considered acceptable in the financial community and otherwise admissible in
court" should be considered in the appraisal proceedings. In addition, Delaware
courts have decided that the statutory appraisal remedy, depending on factual
circumstances, may or may not be a dissenter's exclusive remedy.
 
     The Delaware Court of Chancery will determine the amount of interest, if
any, to be paid upon the amounts to be received by persons whose shares of
Cardiometrics Common Stock have been appraised. The costs of the action may be
determined by such court and taxed upon the parties as the court deems
equitable. The Delaware Court of Chancery may also order that all or a portion
of the expenses incurred by any holder of shares of Cardiometrics Common Stock
in connection with an appraisal, including, without limitation, reasonable
attorneys' fees and the fees and expenses of experts utilized in the appraisal
proceeding, be charged pro rata against the value of all of the shares of
Cardiometrics Common Stock entitled to appraisal.
 
     If any holder of shares of Cardiometrics Common Stock who demands appraisal
of his shares under Section 262 fails to perfect, or effectively withdraws or
loses, his right to appraisal, as provided in the DGCL, the shares of
Cardiometrics Common Stock of such stockholder will receive the Merger
Consideration in accordance with the Reorganization Agreement. A holder may
withdraw his demand for appraisal by delivering to the Surviving Corporation a
written withdrawal of his demand for appraisal and acceptance of the Merger,
except that any such attempt to withdraw made more than 60 days after the
Effective Time will require the written approval of the Surviving Corporation.
Failure to follow the steps required by Section 262 for perfecting appraisal
rights may result in the loss of such rights.
 
     Any holder of shares of Cardiometrics Common Stock who has duly demanded an
appraisal in compliance with Section 262 will not, after the Effective Time, be
entitled to vote the shares of Cardiometrics Common Stock subject to such demand
for any purpose or be entitled to the payment of dividends or other
distributions on those shares (except dividends or other distributions payable
to holders of record of shares of Cardiometrics Common Stock as of a date prior
to the Effective Time).

          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS
 
     The following unaudited pro forma condensed combined financial statements
give effect to the merger of EndoSonics and Cardiometrics pursuant to the
Reorganization Agreement. The unaudited pro forma condensed combined balance
sheet gives effect to the Merger as if it occurred on March 31, 1997. The
unaudited pro forma condensed combined statement of operations gives effect to
the Merger as if it occurred on January 1, 1996.
 
     The pro forma condensed combined financial statements are based on the
historical financial statements of EndoSonics and Cardiometrics, giving effect
to the Merger applying the purchase method of accounting and the assumptions and
adjustments as discussed in the accompanying notes to the pro forma condensed
consolidated financial statements. The pro forma condensed combined financial
statements for the year ended December 31, 1996 have been prepared by EndoSonics
management based upon the audited consolidated financial statements of
EndoSonics for the year then ended and the audited financial statements of
Cardiometrics for the year then ended. The pro forma condensed combined
financial statements as of and for the three months ended March 31, 1997 have
been prepared by EndoSonics management based upon the unaudited consolidated
financial statements of EndoSonics and the unaudited financial statements of
Cardiometrics as of March 31, 1997 and for the three months then ended.
 
     The Merger will be accounted for using the purchase method of accounting.
The unaudited pro forma condensed combined financial statements have been
prepared on the basis of assumptions described in the notes thereto and include
assumptions relating to the allocation of the consideration paid for the assets
and liabilities of Cardiometrics based on preliminary estimates of their fair
value. The actual allocation of such consideration may differ from that
reflected in the unaudited pro forma condensed combined financial statements
after independent valuations and other procedures are completed following the
closing of the Merger. EndoSonics does not expect that the final allocation of
the aggregate purchase price for the Merger will differ materially from the
preliminary allocations. In the opinion of EndoSonics, all adjustments necessary
to present fairly the unaudited pro forma condensed combined financial
statements have been made based on the proposed terms and structure of the
Merger.
 
     The pro forma information is presented for illustrative purposes only and
is not necessarily indicative of the operating results or financial position
that would have occurred if the Merger had been consummated on January 1, 1996
or March 31, 1997, respectively, nor is it necessarily indicative of future
operating results or financial position.
 
     These pro forma condensed combined financial statements should be read in
conjunction with the historical consolidated financial statements and the
related notes thereto of EndoSonics and Cardiometrics incorporated by reference
and included herein, respectively.

- ---------------
(A) Reflects the allocation of the purchase price, based on estimated fair
    values, to the historical Cardiometrics balance sheet. The adjustment
    includes $5.0 million of purchased developed technology, $0.7 million of
    other intangible assets and $0.9 million for write-up of the inventory. Also
    reflects the elimination of the Cardiometrics stockholders' equity accounts.
    The adjustment to cash gives effect to the $3.00 per share to be paid to
    Cardiometrics stockholders plus cash paid for outstanding options. The
    credit to common stock and additional paid-in-capital reflects the value of
    the shares to be issued by EndoSonics to Cardiometrics stockholders.
 
(B) Reflects the one-time write-off of purchased research and development
    identified in the purchase price allocation.
 
(C) Reflects estimated costs attributable to the transaction by both parties
    ($1.5 million each, less $761 in merger expenses incurred by Cardiometrics
    during the three months ended March 31, 1997) and provisions for employee
    termination benefits ($1.2 million). Such adjustments have not been included
    in the pro forma combined condensed statement of operations pursuant to
    Regulation S-X, due to their non-recurring nature. The employee termination
    benefits are accrued pursuant to a "Change in Control Severance Plan" which
    covers all regular, full-time employees of Cardiometrics who are
    involuntarily terminated within twelve months following a Change in Control.
 
(D) Reflects the transfer of CVD common stock with a fair market value of
    approximately $8.6 million to Cardiometrics stockholders and optionholders,
    the resulting gain and Alternative Minimum Tax of approximately $200,000.
    The tax on the gain on the transfer of CVD common stock differs from the
    statutory rate due to the utilization of available net operating losses.

                NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED
                              FINANCIAL STATEMENTS
NOTE 1
 
     The unaudited pro forma condensed combined balance sheet of EndoSonics and
Cardiometrics has been prepared as if the Merger, which is being accounted for
as a purchase, was completed as of March 31, 1997. Based on an average of
closing prices per share of EndoSonics common stock just prior and after January
27, 1997 (the announcement date of the merger) and a recent closing price per
share (May 19, 1997) of CVD common stock, which is held by EndoSonics as an
investment, ($12.75 and $8.375, respectively), such balance sheet reflects the
conversion of Cardiometrics common stock outstanding as of March 31, 1997
(6,960,000) into: (i) approximately 2,436,000 shares of EndoSonics Common Stock,
(ii) approximately 949,000 shares of CVD common stock (reflecting the minimum
exchange ratio of CVD shares proscribed in the Reorganization Agreement), and
(iii) $20.9 million in cash pursuant to the Merger. The calculation excludes
35,156 of warrants to acquire Cardiometrics common stock outstanding at March
31, 1997 which are expected to be net exercised prior to the consummation of the
merger as the effect of such exercise is not material. The pro forma calculation
also excludes the effect of open market purchases by EndoSonics of Cardiometrics
Common Stock. Certain options outstanding at March 31, 1997 to purchase
approximately 892,480 shares of Cardiometrics common stock will be assumed by
EndoSonics pursuant to the Merger and converted into options to purchase
approximately 312,368 shares of EndoSonics Common Stock. In addition, option
holders will receive an aggregate of approximately 78,000 shares of CVD common
stock and cash of $1,722,000 determined in accordance with the terms of the
Reorganization Agreement. The total cost of the proposed Merger is estimated to
be approximately $66.3 million, including transaction costs incurred by
EndoSonics of approximately $1.5 million, which include financial advisory,
legal and accounting fees.
 
     The estimated purchase price consists of the following:

                  transaction costs and termination benefits)......   (5,275)
                                                                     -------
                                                                     $66,337
                                                                     =======

     Pursuant to Regulation S-X, the in-process research and development has
been written-off against the combined accumulated deficit and has not been
reflected in the pro forma condensed combined statement of operations. The
developed technology will be amortized over the estimated related lives of the
related products of eight years. The other intangibles will be amortized over
lives ranging from 3 to 8 years.
 
     As part of the merger consideration, EndoSonics will transfer approximately
1,027,000 shares of CVD common stock with a fair market value of approximately
$8.6 million to the Cardiometrics stockholders and optionholders. Such shares
have a book value of approximately $4.9 million, and therefore EndoSonics will
recognize a gain of approximately $3.7 million upon the transfer. This gain,

and the resulting income tax expense (comprised of Alternative Minimum Tax),
have been reflected as an adjustment to stockholders equity in the unaudited pro
forma condensed combined balance sheet, but excluded from the unaudited pro
forma condensed combined statement of operations due to the non-recurring nature
of the transaction.
 
     The pro forma adjustments include accrued liabilities of $1.5 million (less
$0.8 million incurred by Cardiometrics in the three months ended March 31, 1997)
for costs estimated to be incurred by Cardiometrics in the Merger and $1.2
million of provisions for employee termination benefits.
 
NOTE 2
 
     The unaudited pro forma condensed combined statements of operations of
EndoSonics and Cardiometrics has been prepared as if the Merger was completed as
of January 1, 1996, and reflects the amortization of developed technology,
(other intangibles) and goodwill for the year ended December 31, 1996 and the
three months ended March 31, 1997. In addition, interest income has been reduced
as a result of the assumed payment of cash to effect the Merger on January 1,
1996.
 
     EndoSonics consolidated the operations of CVD through the date of CVD's
initial public offering in June 1996. Thereafter, CVD's results of operations
were reflected in the EndoSonics statement of operations on the equity method.
Had the transfer of the 1,027,000 shares of CVD common stock described in Note 1
above occurred on January 1, 1996, then EndoSonics would have still consolidated
the results of CVD's operations but would have had a reduction in the amount of
CVD's losses recognized on the equity method for the last six months of 1996 and
the first three months of 1997.
 
NOTE 3
 
     The shares used in computing the unaudited pro forma combined net loss per
share for the year ended December 31, 1996 and the three months ended March 31,
1997 are based upon the historical weighted average common shares outstanding
adjusted to reflect the issuance, as of January 1, 1996, of approximately
2,436,000 shares of EndoSonics Common Stock as described in Note 1. Options to
purchase approximately 892,480 shares of Cardiometrics common stock will be
assumed by EndoSonics pursuant to the Merger and converted into options to
purchase approximately 312,368 shares of EndoSonics common stock. The EndoSonics
common stock issuable upon exercise of these stock options have been excluded as
the effect would be anti-dilutive.

GENERAL
 
     Cardiometrics 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. 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 March 1997,
more than 71,000 FloWire guide wires have been sold and approximately 515 FloMap
instruments have been shipped.
 
     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.
 
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 (the
vascular system of the brain) 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 or
blockage within the lumen. PTCA is a procedure in which a balloon tipped
catheter is guided to the lesion and
 
                                       89
<PAGE>   101
 
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 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 cardiac
catheterization laboratory to evaluate the location, size and shape of
atherosclerotic lesions by injecting a radiopaque dye (an ingestible or
injectable viscous liquid that facilitates internal organ imaging via X-ray) 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 (the muscle portion of the heart). 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.

<PAGE>   102
 
     The traditional forms of functional testing, stress electrocardiography
("stress ECG"), stress echocardiography and stress perfusion imaging are each
performed outside of the cardiac catherization laboratory. Functional angiometry
with the FloWire/FloMap system, however, is performed in the cardiac
catherization laboratory 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 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
cardiac catheterization laboratory, often by a physician other than the
interventional cardiologist. The ability to perform functional testing of blood
flow impairment in the cardiac catheterization laboratory 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 cardiac catheterization laboratory
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
 
                                       92
<PAGE>   104
 
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.
 
     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 1,570,000 coronary angiographies performed in the
U.S. in 1994 according to Medical Data International, a market research and
consulting firm ("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 830,000
angiography patients in the U.S. had intermediate lesions. Cardiometrics further
estimates that approximately one-half, or 415,000, 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.
 
                                       93
<PAGE>   105
 
  Diagnostic Application in the International Market
 
     There were approximately 1,300,000 coronary angiographies performed outside
the U.S. in 1995, based on estimates of the Japanese market by MDI and estimates
of the European market by Biomedical Business International, a market research
firm. Of these angiographies, there were approximately 440,000 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 (accessing the internal
organs of the body via a direct puncture through the skin) 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 angioplasty guide wire. Since approximately 50% to 60% of
percutaneous coronary interventions involve balloon angioplasty, according to
Cowen & Company, there are an estimated 470,000 to 560,000 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% to 20%, or approximately
225,000 to 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 (the system of tiny vessels primarily
responsible for transferring oxygenized blood directly to the myocardium) 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 cardiac catheterization laboratory administrators in light of their
expanding roles in purchase decisions.
 
  Domestic Sales and Marketing
 
     A cumulative total of 148 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.
 
     Cardiometrics sells products in the U.S. through a co-distribution
arrangement with Cordis Corporation, a subsidiary of Johnson & Johnson
("Cordis/Johnson & Johnson"). Pursuant to this arrangement, Cordis/Johnson &
Johnson has committed to certain minimum purchases during 1997 and allows
Cardiometrics to continue selling its products on an exclusive basis to 40 key
accounts. These direct sales are handled by six field representatives who have
previous experience with
 
                                       94
<PAGE>   106
 
interventional cardiology companies. The sales force also includes one national
training specialist dedicated to creating and servicing educational sites.
Cardiometrics and Cordis/Johnson & Johnson have committed to negotiate a
transition of these exclusive direct sales accounts to Cordis/Johnson & Johnson
as soon as 1998.
 
     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 cardiac catheterization
laboratory 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 cardiac catheterization
laboratories in Japan.
 
     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. International clinical training centers
are located in and training programs have been held in Paris, France, Essen,
Germany and Milan, Italy.
 
     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/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 sterilized using the gas ethylene oxide.
 
     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 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
and subsequently received a letter from the FDA dated March 21, 1997 requesting
additional information to be submitted to the FDA to support the determination
of whether the WaveWire/WaveMap system is substantially equivalent to a legally
marketed predicate device with regard to its safety and effectiveness. On April
9, 1997, Cardiometrics requested a 90 day extension to submit the requested
data. The FDA, on April 15, 1997, granted the extension until July 21, 1997.
Cardiometrics submitted the requested data on June 9, 1997. 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.
 
                                       96
<PAGE>   108
 
     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.
 
     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 cardiac catheterization laboratory, Cardiometrics does not
view any of these other three technologies as fulfilling the need for functional
testing in the cardiac catheterization laboratory, but they do compete for
limited capital budgets and reimbursement funds and for physician endorsement
and adoption.
 
                                       97
<PAGE>   109
 
     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 narrowing of the lumen, 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 Radi Medical
Systems, Scimed/Boston Scientific and Schneider are developing and preparing to
market new guide wires with pressure measurement capabilities. To Cardiometrics'
knowledge details regarding the performance of 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 reimbursement 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 regula-
 
                                       98
<PAGE>   110
 
tory 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 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, and subsequently received a letter
from the FDA dated March 21, 1997 requesting additional information to be
submitted to the FDA to support the determination of whether the Wave Wire/Wave
Map system is substantially equivalent to a legally marketed predicate device
with regard to the safety and effectiveness. On April 9, 1997, Cardiometrics
requested a 90 day extension to submit the requested data. The FDA, on April 15,
1997, granted the extension until July 21, 1997. Cardiometrics submitted the
requested data on June 9, 1997. Cardiometrics 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 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 vasodilaton (the point when the medial (middle) layer of a blood vessel
is completely relaxed, allowing a natural expansion of the inner lumen to allow
for maximum blood flow), 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 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
 
                                       100
<PAGE>   112
 
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.
 
     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
 
                                       101
<PAGE>   113
 
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.
 
     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
 
                                       102
<PAGE>   114
 
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 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

by Japan's Ministry of Health since 1992.
 
FACILITIES
 
     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
expired in March 1997, upon which Cardiometrics began occupying such facility
pursuant to a month-to-month tenancy. Cardiometrics believes its facilities will
be adequate through 1997.
 
EMPLOYEES
 
     As of May 30, 1997, Cardiometrics had 99 full-time employees, of whom 17
were involved in research and development, 54 in manufacturing, 17 in sales and
marketing and 11 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.
 
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
and the individual defendants named in the complaint deny the material
allegations asserted against them. Cardiometrics intends to defend vigorously
itself and the named individual defendants against the allegations in the
complaint.

             CARDIOMETRICS 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 cardiac catheterization laboratory 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 approval of the Merger by the stockholders of Cardiometrics, at a
stockholders meeting currently expected to be held in July 1997 and the
satisfaction of certain other closing conditions.
 
     Cardiometrics has not been profitable since inception and, as of March 31,
1997, had an accumulated deficit of $35.5 million, $25.7 million of which has
been incurred since Cardiometrics restructured its operations in 1990. Further
growth in the sales volume of Cardiometrics' products and
 
                                       106
<PAGE>   118
 
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.

  Three Months Ended March 31, 1997 Compared to Three Months Ended March 31,
1996
 
     Sales.  Sales increased 10% during the three months ended March 31, 1997
compared to the three months ended March 31, 1996 to $3,467,000 from $3,166,000.
Sales for the first quarter of 1997 increased over the corresponding period of
1996 primarily as a result of an increase in sales volume of FloWire units. The
increase in FloWire unit shipments was due in part to a U.S. co-distribution
agreement that the Company entered into in March 1997 with Cordis Corporation, a
Johnson & Johnson Company. The increase in FloWire sales was partially offset by
no sales of AccuTrac guide wires during the three month period ended March 31,
1997 as compared to $420,000 of sales during the similar period in 1996.
 
     Cost of sales.  Cost of sales increased four percent during the three
months ended March 31, 1997 compared to the three months ended March 31, 1996 to
$1,391,000 from $1,332,000. As a percentage of sales, cost of sales decreased to
40% for the three months ended March 31, 1997 compared to 42% in the same three
month period of 1996. This decrease was primarily the result of a greater
proportion of FloWire sales as a percentage of total sales partially offset by a
lower gross margin realized on instrument sales.
 
     Research and development.  Research and development expenses increased 22%
during the three months ended March 31, 1997 over the three month period ended
March 31, 1996 to $862,000 from $709,000. As a percentage of sales, research and
development expenses increased to 25% in the first quarter of 1997 from 22% in
the same quarter of 1996. This increase was due to increased spending on
clinical studies, which the Company includes in research and development
expenses. The expenditures on clinical studies included both on-going studies
and studies initiated during the first three months of 1997. The Company plans
to continue its expenditures in research and development, including additional
expenditures on clinical studies.
 
     Selling, general and administrative.  Selling, general and administrative
expenses increased 22% during the three months ended March 31, 1997 over the
three months ended March 31, 1996 to
 
                                       107
<PAGE>   119
 
$2,189,000 from $1,792,000. Selling, general and administrative expenses as a
percentage of sales increased during the first quarter of 1997 to 63% as
compared to 57% during the first quarter of 1997. The increase in selling,
general and administrative expenses was principally the results of increased
staffing and associated expenses, additional sales and marketing programs and
expenses associated with increased sales volumes.
 
     Merger expenses.  The Company incurred $761,000 of expenses in the first
quarter of 1997 related to the proposed merger with EndoSonics. These expenses
consisted primarily of expenditures for professional legal services and
investment banking fees. The Company expects to incur additional expenses
related to the proposed merger with EndoSonics as least through the second
quarter of 1997.
 
  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.
 
                                       108
<PAGE>   120
 
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. For the three month period ended March 31,
1997 the Company's cash used in operations was $1,623,000.
 
     At March 31, 1997, Cardiometrics' principal sources of liquidity included
an aggregate of $15,596,000 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.

                      COMPARISON OF RIGHTS OF STOCKHOLDERS
                      OF ENDOSONICS, CVD AND CARDIOMETRICS
 
     Cardiometrics, EndoSonics and CVD are all Delaware corporations and
therefore Cardiometrics stockholders' rights will remain governed by the
Delaware General Corporation Law after the Merger. Cardiometrics stockholders'
rights will, however, be governed after the Merger by EndoSonics' and CVD's
respective Certificates of Incorporation and Bylaws.
 
     The following is a summary of the material differences between the rights
of holders of Cardiometrics Common Stock and the rights of holders of EndoSonics
Common Stock and the rights of holders of CVD Common Stock at the date hereof.
These differences arise from differences between Cardiometrics' Certificate of
Incorporation (the "Cardiometrics Certificate") and Cardiometrics' Bylaws (the
"Cardiometrics Bylaws") and EndoSonics' Certificate of Incorporation (the
"EndoSonics Certificate") and EndoSonics' Bylaws (the "EndoSonics Bylaws") and
CVD's Certificate of Incorporation (the "CVD Certificate") and CVD's Bylaws (the
"CVD Bylaws"), respectively.
 
STOCKHOLDER PROPOSALS; DIRECTOR NOMINATIONS
 
     The EndoSonics Bylaws provide that no stockholder proposals or nominations
for directors of EndoSonics by any person other than the EndoSonics Board of
Directors may be presented to any meeting of stockholders unless the person
making the proposal or nomination is a record stockholder and has delivered a
written notice to the secretary of EndoSonics no less than 60 days nor more than
90 days in advance of the stockholder meeting; provided, however, that in the
event that less than 70 days notice or prior public disclosure of the date of
the meeting is given or made to stockholders, notice by the stockholder to be
timely must be so received not later than the close of business on the 10th day
following the day on which such notice of the date of the meeting was mailed or
such public disclosure was made.
 
     The CVD Bylaws provide that no stockholder proposals or nominations for
directors of CVD by any person other than the CVD Board of Directors may be
presented to any meeting of stockholders unless the person making the proposal
or nomination is a record stockholder and has delivered a written notice to the
secretary of CVD no less than 90 days in advance of the stockholder meeting;
provided, however, that in the event that less than 100 days notice or prior
public disclosure of the date of the meeting is given or made to stockholders,
notice by the stockholder to be timely must be so received not later than the
close of business on the 10th day following the day on which such notice of the
date of the meeting was mailed or such public disclosure was made.
 
     The Cardiometrics Bylaws provide that no stockholder proposals or
nominations for directors of Cardiometrics by any person other than the
Cardiometrics Board of Directors may be presented to any meeting of stockholders
unless the person making the proposal or nomination is a record stockholder and
has delivered a written notice to the secretary of Cardiometrics no less than 30
days nor more than 60 days in advance of the stockholder meeting.
 
AMENDMENT TO GOVERNING DOCUMENTS
 
     The Delaware General Corporation Law (the "DGCL") requires a vote of the
corporation's board of directors followed by the affirmative vote of a majority
of the outstanding stock of each class entitled to vote for any amendment to the
certificate of incorporation, unless a greater level of approval is required by
the certificate of incorporation. If an amendment would alter the powers,
preferences or special rights of a particular class or series of stock so as to
affect them adversely, the class or series shall be given the power to vote as a
class notwithstanding the absence of any specifically enumerated power in the
certificate of incorporation. While neither the Cardiometrics Certificate nor
the CVD Certificate requires a greater level of approval for an amendment
thereto, the EndoSonics Certificate requires the affirmative vote of not less
than sixty-six and two-thirds percent (66 2/3%) of the total voting power of all
outstanding shares of stock entitled to vote thereon for the repeal or amendment
of certain provisions of the EndoSonics Certificate relating to (i) amendment of
the EndoSonics Bylaws
 
                                       112
<PAGE>   124
 
to increase or reduce the authorized number of directors, (ii) the number of
directors of EndoSonics, (iii) the ability of stockholders to take corporate
action, (iv) the liability of directors of EndoSonics for breach of fiduciary
duty and (v) the amendment of the EndoSonics Certificate.
 
     The DGCL also states that the power to adopt, amend or repeal the by-laws
of a corporation shall be in the stockholders entitled to vote, provided that
the corporation in its certificate of incorporation may confer such power on the
board of directors in addition to the stockholders. Each of the Cardiometrics
Certificate, the EndoSonics Certificate and the CVD Certificate expressly
authorizes the respective boards of directors to make, repeal, alter, amend and
rescind the Cardiometrics Bylaws, EndoSonics Bylaws and CVD Bylaws,
respectively; provided, however, that the EndoSonics Certificate provides that
any amendment of the EndoSonics Bylaws relating to the increase or reduction of
the authorized number of directors shall require a resolution adopted by the
affirmative vote of not less than sixty-six and two-thirds percent (66 2/3%) of
the directors.
 
STOCKHOLDER CONSENT IN LIEU OF MEETING
 
     Under the DGCL, unless otherwise provided in the certificate of
incorporation, any action required to be taken or which may be taken at an
annual or special meeting of stockholders may be taken without a meeting if a
consent in writing is signed by the holders of outstanding stock having not less
than the minimum number of votes that would be necessary to authorize such
action at a meeting at which all shares entitled to vote were present and voted.
Each of the EndoSonics Certificate, CVD Certificate and Cardiometrics
Certificate each provide that stockholders may not take any action by written
consent in lieu of a meeting.
 
ANTI-TAKEOVER PROVISIONS
 
     The Cardiometrics Certificate provides that Cardiometrics' Board of
Directors is divided into two classes, with each class serving a staggered
two-year term. The classification system of electing directors may have the
effect of discouraging third parties from making a tender offer or otherwise
attempting to obtain control of the Company and may maintain the incumbency of
the Board of Directors by making it more difficult for stockholders to replace a
majority of the directors.
 
     The Cardiometrics Bylaws provide that special meetings of its stockholders
may only be called by the president or a majority of the Board of Directors. The
CVD Bylaws provide that special meetings of its stockholders may only be called
by the president, a majority of the Board of Directors, or stockholders owning
not less than 50% of the entire capital stock of the corporation issued and
outstanding and entitled to vote. The EndoSonics Certificate provides that
special meetings of its stockholders may only be called by the president or
Chairman of the Board or a majority of the Board of Directors; EndoSonics
stockholders may not call a special meeting of stockholders.
 
CUMULATIVE VOTING
 
     Neither the EndoSonics Certificate, the Cardiometrics Certificate nor the
CVD Certificate nor the EndoSonics Bylaws, the Cardiometrics Bylaws or the CVD
Bylaws provide for cumulative voting in elections of directors. Therefore, under
Delaware law, cumulative voting rights are not available to EndoSonics,
Cardiometrics or CVD stockholders.
 
     The foregoing discussion of certain similarities and material differences
between the rights of Cardiometrics stockholder, the rights of EndoSonics
stockholders and the rights of the CVD stockholders under the respective
Certificates of Incorporation and Bylaws is only a summary of certain provisions
and does not purport to be a complete description of such similarities and
differences, and is qualified in its entirety by reference to the General
Corporation Law of Delaware, the common law thereunder and the full text of the
Certificates of Incorporation and Bylaws of each of EndoSonics, CVD and
Cardiometrics.

Meeting of Stockholders, the deadline for stockholders to submit proposals to be
considered for inclusion in EndoSonics' proxy statement for the EndoSonics 1997
Annual Meeting of Stockholders was December 23, 1996.
 
     As described in Cardiometrics' proxy statement relating to its 1996 Annual
Meeting of Stockholders, stockholder proposals that are intended to be presented
at Cardiometrics' 1997 Annual Meeting of Stockholders (if the Merger is not
consummated) which are eligible for inclusion in Cardiometrics' proxy statement
for that meeting under the applicable rules of the Commission must have been
received by Cardiometrics no later than February 28, 1997 in order to be
included in the proxy statement and related proxy materials for that meeting.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
To the Board of Directors and Stockholders
Cardiometrics, Inc.
 
     We have audited the accompanying balance sheets of Cardiometrics, Inc., as
of December 31, 1996 and 1995, and the related statements of operations,
stockholders' equity and cash flows for each of the three years in the period
ended December 31, 1996. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on theses
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Cardiometrics, Inc. at
December 31, 1996 and 1995 and the results of its operations and its cash flows
for each of the three years in the period ended December 31, 1996, in conformity
with generally accepted accounting principles.

                         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).

  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. Deferred revenue relates to service
maintenance arrangements, whereby customers pay in advance of services being
performed. Such amounts are recognized over the contractual period or as
services are provided.
 
  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:

     Pro forma net loss per share for 1995 and 1994 has been computed as
described above and also gives effect to the conversion of convertible preferred
shares not included above that were automatically converted upon the completion
of the Company's initial public offering (using the if-converted method from the
original date of issuance).
 
  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

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

  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.

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.

     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, as subsequently amended (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 July 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 amendment to
the Agreement and Plan of Reorganization (which values are subject to change),
approximated $8.00 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 and the individual
defendants named in the complaint deny the material allegations asserted against
them. Cardiometrics intends to defend vigorously itself and the named individual
defendants against the allegations in the complaint.

                         NOTES TO FINANCIAL STATEMENTS
 
1.  BASIS OF PRESENTATION
 
     The accompanying unaudited financial statements for the three month periods
ended March 31, 1997 and 1996 include all adjustments (consisting of normal
recurring adjustments) which the Company considers necessary for a fair
presentation of the operating results and cash flows for those periods.
 
     Certain information and footnote disclosures required by generally accepted
accounting principles for complete financial statements have been omitted
pursuant to the rules and regulations of the Securities and Exchange Commission
("SEC"), although the Company believes that the disclosures included are
adequate to make the information presented not misleading. These financial
statements should be read in conjunction with the audited financial statements
and footnotes included elsewhere in this Proxy/Prospectus.
 
     Results for the interim period ended March 31, 1997 are not necessarily
indicative of the results for future interim periods or for the entire year
ending December 31, 1997.
 
2.  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, as subsequently amended (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, which is currently
expected to be held in July 1997, and the satisfaction of certain other closing
conditions. 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. Pursuant to the Reorganization Agreement, stockholders of
Cardiometrics will receive shares in EndoSonics, shares in CardioVascular
Dynamics, Inc. and cash, (the "Merger Consideration") which, based on closing
prices on the last trading day prior to the amendment to the Agreement and Plan
of Reorganization (which values are subject to change), approximated $8.00 per
share of Cardiometrics common stock. Since the date of the execution of the
agreement, the value of the Merger Consideration has fluctuated between $7.30
and $9.05 per share and as of June 11, 1997 was approximately $8.05 per share.
 
     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.
 
3.  NET LOSS PER SHARE
 
     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

computations for the three months ended March 31, 1997 and March 31, 1996, as
their effect is antidilutive.
 
     In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, Earnings per Share, which is required to be adopted on December 31,
1997. At that time, the Company will be required to change the method currently
used to compute loss per share and to restate all prior periods. Under the new
requirements for calculating primary earnings per share, the dilutive effect of
stock options will be excluded. As a result of the antidilutive effect of
equivalent shares from stock options and warrants stated above, the impact of
Statement 128 on the calculation of primary earnings per share for the quarter
ended March 31, 1997 and March 31, 1996 is not expected to be material.

5.  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 and the individual
defendants named in the complaint deny the material allegations asserted against
them. Cardiometrics intends to defend vigorously itself and the named individual
defendants against the allegations in the complaint.

                      AGREEMENT AND PLAN OF REORGANIZATION
 
     This AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is made and
entered into as of January 26, 1997, by and among EndoSonics Corporation, a
Delaware corporation ("Acquiror"), River Acquisition Corporation, a Delaware
corporation ("Merger Sub") and wholly-owned subsidiary of Acquiror, and
Cardiometrics, Inc., a Delaware corporation ("Target").
 
                                    RECITALS
 
     A. The Boards of Directors of Target, Acquiror and Merger Sub believe it is
in the best interests of their respective companies and the stockholders of
their respective companies that Target and Merger Sub combine into a single
company through the statutory merger of Merger Sub with and into Target (the
"Merger") and, in furtherance thereof, have approved the Merger.
 
     B. Pursuant to the Merger, among other things, the outstanding shares of
Target Common Stock, $.0.01 par value ("Target Common Stock"), shall be
converted into shares of Acquiror Common Stock, $0.001 par value ("Acquiror
Common Stock"), at the rate set forth herein, shares of Common Stock ("VC Common
Stock") of CardioVascular Dynamics, Inc., a Delaware corporation ("VC"), at the
rate set forth herein, and cash, at the rate set forth herein.
 
     C. Target, Acquiror and Merger Sub desire to make certain representations
and warranties and other agreements in connection with the Merger.
 
     D. Concurrent with the execution of this Agreement and as an inducement to
Acquiror and Merger Sub to enter into this Agreement, (a) Target and Acquiror
have entered into a stock option agreement dated the date hereof (the "Stock
Option Agreement") providing for the purchase by Acquiror of newly-issued shares
of Target's Common Stock, and (b) certain of the affiliates of Target who are
stockholders, officers or directors have on the date hereof entered into an
agreement to vote the shares of Target's Common Stock owned by such person to
approve the Merger and against any competing proposals.
 
     NOW, THEREFORE, in consideration of the covenants and representations set
forth herein, and for other good and valuable consideration, the parties agree
as follows:
 
                                   ARTICLE I
 
                                   THE MERGER
 
     1.1  The Merger.  At the Effective Time (as defined in Section 1.2) and
subject to and upon the terms and conditions of this Agreement, the Certificate
of Merger attached hereto as Exhibit A (the "Certificate of Merger") and the
applicable provisions of the Delaware General Corporation Law ("Delaware Law"),
Merger Sub shall be merged with and into Target, the separate corporate
existence of Merger Sub shall cease and Target shall continue as the surviving
corporation. Target as the surviving corporation after the Merger is hereinafter
sometimes referred to as the "Surviving Corporation."
 
     1.2  Closing; Effective Time.  The closing of the transactions contemplated
hereby (the "Closing") shall take place as soon as practicable after the
satisfaction or waiver of each of the conditions set forth in Article VI hereof
or at such other time as the parties hereto agree (the "Closing Date"). The
Closing shall take place at the offices of Acquiror's legal counsel, or at such
other location as the parties hereto agree. In connection with the Closing, the
parties hereto shall cause the Merger to be consummated by filing the
Certificate of Merger with the Secretary of State of the State of Delaware, in
accordance with the relevant provisions of Delaware Law (the time of such filing
or such later time as is set forth in the Certificate of Merger being the
"Effective Time").
 
     1.3  Effect of the Merger.  At the Effective Time, the effect of the Merger
shall be as provided in this Agreement, the Certificate of Merger and the
applicable provisions of Delaware Law. Without
 
                                      AA-1
<PAGE>   151
 
limiting the generality of the foregoing, and subject thereto, at the Effective
Time, all the property, rights, privileges, powers and franchises of Target and
Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities
and duties of Target and Merger Sub shall become the debts, liabilities and
duties of the Surviving Corporation.
 
     1.4  Certificate of Incorporation; Bylaws.
 
          (a) At the Effective Time, the Certificate of Incorporation of Merger
     Sub, as in effect immediately prior to the Effective Time, shall be the
     Certificate of Incorporation of the Surviving Corporation until thereafter
     amended as provided by Delaware Law and such Certificate of Incorporation;
     provided, however, that Article I of the Certificate of Incorporation of
     the Surviving Corporation shall be amended to read as follows: "The name of
     the corporation is Cardiometrics, Inc."
 
          (b) The Bylaws of Merger Sub, as in effect immediately prior to the
     Effective Time, shall be the Bylaws of the Surviving Corporation until
     thereafter amended.
 
     1.5  Directors and Officers.  At the Effective Time, the directors of the
Surviving Corporation shall be Reinhard J. Warnking and Donald D. Huffman. The
officers of the Surviving Corporation shall be the initial officers of Merger
Sub, until their respective successors are duly elected or appointed and
qualified.
 
     1.6  Effect on Capital Stock.  By virtue of the Merger and without any
action on the part of Merger Sub, Target or the holders of any of the following
securities:
 
          (a) Conversion of Target Common Stock.  At the Effective Time, each
     share of Target Common Stock issued and outstanding immediately prior to
     the Effective Time (other than any shares of Target Common Stock to be
     canceled pursuant to Section 1.6(b) and shares, if any held by persons who
     have not voted such shares for approval of the Merger and with respect to
     which such persons shall become entitled to appraisal rights in accordance
     with Section 262 of the Delaware Law ("Dissenting Shares")) will be
     canceled and extinguished and be converted automatically into the right to
     receive:
 
             (i) an amount in cash equal to $2.00 (the "Cash Consideration");
 
             (ii) 0.35 shares of Acquiror Common Stock (the "Stock
        Consideration" and the "Stock Consideration Exchange Ratio"); and
 
             (iii) 0.20 shares of VC Common Stock held of record by Acquiror as
        of the date hereof (the "VC Exchange Ratio"), subject to adjustment as
        set forth below (the "VC Consideration" and collectively with the Cash
        Consideration and Stock Consideration, the "Merger Consideration"). The
        VC Exchange Ratio shall be subject to increase such that based on the
        average of the closing prices of Acquiror Common Stock and the average
        of the closing prices of VC Common Stock for the ten trading days
        immediately preceding (and including) the third trading day prior to the
        Target Stockholders' Meeting, the Merger Consideration shall be equal to
        $9.00 (the "Price"); provided, however, that if based on such
        calculation the VC Exchange Ratio would be greater than .2636, the VC
        Exchange Ratio shall be .2636 (the "Floor"); provided further, that at
        Acquiror's option, in lieu of such increase of the VC Exchange Ratio,
        the Cash Consideration may be increased such that, based on the average
        of the closing prices of Acquiror Common Stock and the average of the
        closing prices of VC Common Stock for the ten trading days immediately
        preceding (and including) the third trading day prior to the Target
        Stockholders' Meeting, the Merger Consideration shall be equal to $9.00;
        and provided further that, notwithstanding the foregoing, the VC
        Exchange Ratio shall not be less than 0.20 and the Cash Consideration
        shall not be less than $2.00.
 
          (b) Cancellation of Target Common Stock Owned by Acquiror or
     Target.  At the Effective Time, all shares of Target Common Stock that are
     owned by Target as treasury stock and each share of Target Common Stock
     owned by Acquiror or any direct or indirect wholly-owned subsidiary of
 
                                      AA-2
<PAGE>   152
 
     Acquiror or of Target immediately prior to the Effective Time shall be
     canceled and extinguished without any conversion thereof.
 
          (c) Target Stock Option Plans.  Immediately prior to the Effective
     Time, each outstanding option under the Target 1985 Stock Option Plan, the
     Target 1995 Stock Option Plan and the Target 1995 Stock Incentive Plan
     (collectively, the "Target Stock Option Plans") shall vest in full and
     become exercisable for any or all of the shares of Target Common Stock at
     the time subject to that option, with such accelerated vesting to be
     conditioned, however, upon the actual consummation of the Merger. Each
     share of Target Common Stock acquired under the Target Option Plans through
     the exercise of an outstanding option effected immediately prior to the
     Effective Time shall be canceled and extinguished at the Effective Time and
     converted automatically into the right to receive the Merger Consideration
     payable per share of Target Common Stock. However, if the Merger is not
     consummated, the option exercise price paid for any shares of Target Common
     Stock purchased under the Target Option Plans on the basis of the
     acceleration provided under this Section 1.6(c) shall be refunded by
     Target, and the vesting schedule for those shares shall revert to the
     schedule in effect immediately prior to acceleration hereunder. Any options
     which remain outstanding under the Target Option Plans at the Effective
     Time shall be cancelled in accordance with the provisions of Section 5.10.
 
          (d) Capital Stock of Merger Sub.  At the Effective Time, each share of
     Common Stock, $.0001 par value, of Merger Sub ("Merger Sub Common Stock")
     issued and outstanding immediately prior to the Effective Time shall be
     converted into and exchanged for one validly issued, fully paid and
     nonassessable share of Common Stock, $.0001 par value, of the Surviving
     Corporation. Each stock certificate of Merger Sub evidencing ownership of
     any such shares shall continue to evidence ownership of such shares of
     capital stock of the Surviving Corporation.
 
          (e) Adjustments to Exchange Ratio.  The exchange ratio for the shares
     of Acquiror Common Stock, the VC Exchange Ratio, the Price, the Floor and
     the Cash Consideration shall be adjusted to reflect fully the effect of any
     stock split, reverse split, stock dividend (including any dividend or
     distribution of securities convertible into Acquiror Common Stock, Target
     Common Stock or VC Common Stock), reorganization, recapitalization or other
     like change with respect to Acquiror Common Stock, Target Common Stock or
     VC Common Stock occurring after the date hereof and prior to the Effective
     Time.
 
          (f) Fractional Shares.  No fraction of a share of Acquiror Common
     Stock or VC Common Stock shall be issued, but in lieu thereof each holder
     of shares of Target Common Stock who would otherwise be entitled to a
     fraction of a share of Acquiror Common Stock or VC Common Stock (after
     aggregating all fractional shares of Acquiror Common Stock or VC Common
     Stock to be received by such holder) shall receive from Acquiror an amount
     of cash (rounded to the nearest whole cent) equal to the product of (i)
     such fraction, multiplied by (ii) the average of the closing prices of a
     share of Acquiror Common Stock or VC Common Stock, as applicable, for the
     ten trading days immediately preceding (and including) the third trading
     day prior to the Target Stockholders' Meeting, as reported on the Nasdaq
     National Market.
 
          (h) Appraisal Rights.  Any Dissenting Shares shall not be converted
     into the right to receive the consideration set forth in Section 1.6(a) but
     shall instead be converted into the right to receive such consideration as
     may be determined to be due with respect to such Dissenting Shares pursuant
     to Delaware Law. Target agrees that, except with the prior written consent
     of Acquiror, or as required under Delaware Law, it will not voluntarily
     make any payment with respect to, or settle or offer to settle, any demand
     with respect to Dissenting Shares. Each holder of Dissenting Shares
     ("Dissenting Stockholder") who, pursuant to the provisions of Delaware Law,
     becomes entitled to payment of the fair value for shares of Target Common
     Stock shall receive payment therefor (but only after the value therefor
     shall have been agreed upon or finally determined pursuant to such
     provisions). If, after the Effective Time, any Dissenting Shares shall lose
     their status as Dissenting Shares, Acquiror shall issue and deliver, upon
     surrender by such shareholder
 
                                      AA-3
<PAGE>   153
 
     of certificate or certificates representing shares of Target Common Stock,
     the consideration to which such stockholder would otherwise be entitled
     under this Section 1.6 and the Certificate of Merger.
 
     1.7  Surrender of Certificates.
 
          (a) Exchange Agent.  Chase Mellon Shareholder Services shall act as
     exchange agent (the "Exchange Agent") in the Merger.
 
          (b) Acquiror to Provide Common Stock and Cash.  Promptly after the
     Effective Time (but in no event later than five (5) business days
     thereafter), Acquiror shall make available to the Exchange Agent for
     exchange in accordance with this Article I, through such reasonable
     procedures as Acquiror may adopt, (1) the shares of Acquiror Common Stock
     issuable pursuant to Section 1.6(a)(ii), (2) the shares of VC Common Stock
     issuable pursuant to Section 1.6(a)(iii), (3) the cash issuable pursuant to
     Section 1.6(a)(i), and (4) cash in an amount sufficient to permit payment
     of cash in lieu of fractional shares pursuant to Section 1.6(f).
 
          (c) Exchange Procedures.  Within five (5) business days after the
     Effective Time, the Surviving Corporation shall cause to be mailed to each
     holder of record of a certificate or certificates (the "Certificates")
     which immediately prior to the Effective Time represented outstanding
     shares of Target Common Stock, whose shares were converted into the right
     to receive the Merger Consideration pursuant to Section 1.6, (i) a letter
     of transmittal (which shall specify that delivery shall be effected, and
     risk of loss and title to the Certificates shall pass, only upon receipt of
     the Certificates by the Exchange Agent, and shall be in such form and have
     such other provisions as Acquiror may reasonably specify) and (ii)
     instructions for use in effecting the surrender of the Certificates in
     exchange for the Merger Consideration. Upon surrender of a Certificate for
     cancellation to the Exchange Agent, together with such letter of
     transmittal, duly completed and validly executed in accordance with the
     instructions thereto, the holder of such Certificate shall be entitled to
     receive in exchange therefor the Merger Consideration and the Certificate
     so surrendered shall forthwith be canceled. Until so surrendered, each
     outstanding Certificate that, prior to the Effective Time, represented
     shares of Target Common Stock shall be deemed from and after the Effective
     Time, for all corporate purposes, other than the payment of dividends, to
     evidence the right to receive the Merger Consideration. Promptly after the
     Effective Time, the Surviving Corporation shall cause to be mailed to each
     holder of an option under the Target Option Plans which is cancelled in
     accordance with Section 5.10 instructions for use in effecting the
     surrender of the documentation for that option in exchange for the
     consideration payable per option share under Section 5.10. Upon surrender
     of the option documentation for cancellation to the Exchange Agent or to
     such other agent or agents as may be appointed by Acquiror, the holder of
     such option shall be entitled to receive in exchange therefor the
     consideration payable per option share under Section 5.10, and the option
     shall be cancelled and the holder of that option shall have no further
     right to acquire any securities thereunder. Until so surrendered, each such
     outstanding option will be deemed from and after the Effective Time, for
     all corporate purposes, to evidence the ownership of the right to receive
     the consideration payable per option share under Section 5.10.
 
          (d) Distributions With Respect to Unexchanged Shares.  No dividends or
     other distributions with respect to Acquiror Common Stock with a record
     date after the Effective Time shall be paid to the holder of any
     unsurrendered Certificate with respect to the shares of Acquiror Common
     Stock represented thereby until the holder of record of such Certificate
     shall surrender such Certificate. Subject to applicable law, following
     surrender of any such Certificate, there shall be paid to the record holder
     of the certificates representing whole shares of Acquiror Common Stock
     issued in exchange therefor, without interest, at the time of such
     surrender, the amount of any such dividends or other distributions with a
     record date after the Effective Time theretofore payable (but for the
     provisions of this Section 1.7(d)) with respect to such shares of Acquiror
     Common Stock.
 
                                      AA-4
<PAGE>   154
 
          (e) Transfers of Ownership.  If any certificate for shares of Acquiror
     Common Stock or VC Common Stock is to be issued in a name other than that
     in which the Certificate surrendered in exchange therefor is registered, it
     will be a condition of the issuance thereof that the Certificate so
     surrendered will be properly endorsed and otherwise in proper form for
     transfer and that the person requesting such exchange will have paid to
     Acquiror or any agent designated by it any transfer or other taxes required
     by reason of the issuance of a certificate for shares of Acquiror Common
     Stock or VC Common Stock in any name other than that of the registered
     holder of the Certificate surrendered, or established to the satisfaction
     of Acquiror or any agent designated by it that such tax has been paid or is
     not payable.
 
          (f) No Liability.  Notwithstanding anything to the contrary in this
     Section 1.7, none of the Exchange Agent, the Surviving Corporation or any
     party hereto shall be liable to any person for any amount properly paid to
     a public official pursuant to any applicable abandoned property, escheat or
     similar law.
 
          (g) Dissenting Shares.  The provisions of this Section 1.7 shall also
     apply to Dissenting Shares that lose their status as such, except that the
     obligations of Acquiror under this Section 1.7 shall commence on the date
     of loss of such status and the holder of such shares shall be entitled to
     receive in exchange for such shares the consideration to which such holder
     is entitled pursuant to Section 1.6 hereof.
 
     1.8  No Further Ownership Rights in Target Common Stock.  The Merger
Consideration shall be deemed to have been issued in full satisfaction of all
rights pertaining to such shares of Target Common Stock, and there shall be no
further registration of transfers on the records of the Surviving Corporation of
shares of Target Common Stock which were outstanding immediately prior to the
Effective Time. If, after the Effective Time, Certificates are presented to the
Surviving Corporation for any reason, they shall be canceled and exchanged as
provided in this Article I. The consideration payable per option share under
Section 5.10 with respect to the options outstanding under the Target Option
Plans at the Effective Time shall be full satisfaction of all rights the holders
of those options would otherwise have to acquire shares of Target Common Stock
under those options, and those options shall accordingly be cancelled, together
with the Target Option Plans, and no further shares of Target Common Stock shall
be issuable under the cancelled options or Target Option Plans.
 
     1.9  Lost, Stolen or Destroyed Certificates.  In the event any Certificates
shall have been lost, stolen or destroyed, the Exchange Agent shall issue in
exchange for such lost, stolen or destroyed Certificates, upon the making of an
affidavit of that fact by the holder thereof, the Merger Consideration (and cash
in lieu of fractional shares) as may be required pursuant to Section 1.6;
provided, however, that Acquiror may, in its discretion and as a condition
precedent to the issuance thereof, require the owner of such lost, stolen or
destroyed Certificates to deliver a bond in such sum as it may reasonably direct
as indemnity against any claim that may be made against Acquiror, the Surviving
Corporation or the Exchange Agent with respect to the Certificates alleged to
have been lost, stolen or destroyed.
 
     1.10  Taking of Necessary Action; Further Action.  If, at any time after
the Effective Time, any further action is necessary or desirable to carry out
the purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of Target and Merger Sub, the officers and directors of Target
and Merger Sub are fully authorized in the name of their respective corporations
or otherwise to take, and will take, all such lawful and necessary action, so
long as such action is not inconsistent with this Agreement.
 
                                   ARTICLE II
 
                    REPRESENTATIONS AND WARRANTIES OF TARGET
 
     In this Agreement, any reference to any event, change, condition or effect
being "material" with respect to any entity or group of entities means any
material event, change, condition or effect related to the condition (financial
or otherwise), properties, assets (including intangible assets), liabilities,
 
                                      AA-5
<PAGE>   155
 
business, operations or results of operations as presently conducted of such
entity or group of entities. In this Agreement, any reference to a "Material
Adverse Effect" with respect to any entity or group of entities means any event,
change or effect that is materially adverse to the condition (financial or
otherwise), properties, assets, liabilities, business, operations or results of
operations as presently conducted of such entity and its subsidiaries, taken as
a whole;
 
     Except as disclosed in a document of even date herewith and delivered by
Target to Acquiror prior to the execution and delivery of this Agreement (the
"Target Disclosure Schedule"), Target represents and warrants to Acquiror and
Merger Sub as follows:
 
     2.1  Organization, Standing and Power.  Target is a corporation duly
organized, validly existing and in good standing under the laws of its
jurisdiction of organization. Target has the corporate power to own its
properties and to carry on its business as now being conducted and as proposed
to be conducted prior to the Effective Time and is duly qualified to do business
and is in good standing in each jurisdiction in which the failure to be so
qualified and in good standing would have a Material Adverse Effect on Target.
Target has delivered or made available a true and correct copy of the Restated
Certificate of Incorporation (the "Certificate of Incorporation") and Bylaws of
Target, each as amended to date, to Acquiror. Target is not in violation of any
of the provisions of its Certificate of Incorporation or Bylaws. Except as
disclosed in the Target SEC Documents (as defined in Section 2.4), Target does
not directly or indirectly own any equity or similar interest in, or any
interest convertible or exchangeable or exercisable for, any equity or similar
interest in, any corporation, partnership, joint venture or other business
association or entity.
 
     2.2  Capital Structure.  The authorized capital stock of Target consists of
15,000,000 shares of Common Stock, $0.01 par value, and 5,000,000 shares of
Preferred Stock, $0.01 par value (20,000 of which have been designated as Series
A Junior Participating Preferred Stock ("Series A Preferred Stock")), of which
there were issued and outstanding as of the close of business on January 23,
1997, 6,933,253 shares of Common Stock and no shares of Preferred Stock. As of
the date hereof, there are no other outstanding shares of capital stock or
voting securities and no other outstanding commitments to issue any shares of
capital stock or voting securities of Target other than pursuant to the Stock
Option Agreement, the exercise of options outstanding as of such date under the
Target Stock Option Plans, pursuant to the Target Employee Stock Purchase Plan
(the "Target ESPP"), pursuant to the Rights Agreement dated as of December 3,
1996, between Target and The First National Bank of Boston (the "Rights
Agreement"), or pursuant to any outstanding warrants. All outstanding shares of
Target Common Stock are duly authorized, validly issued, fully paid and
non-assessable and are free of any liens or encumbrances other than any liens or
encumbrances created by or imposed upon the holders thereof, and are not subject
to preemptive rights or rights of first refusal created by statute, the
Certificate of Incorporation or Bylaws of Target or any agreement to which
Target is a party or by which it is bound. As of the close of business on
January 23, 1997, Target has reserved (i) 1,399,914 shares of Common Stock for
issuance to employees, consultants and directors pursuant to the Target Stock
Option Plans, of which 338,576 shares have been issued pursuant to option
exercises or direct stock purchases, 931,255 shares are subject to outstanding,
unexercised options, and no shares are subject to outstanding stock purchase
rights, (ii) 100,000 shares of Common Stock for issuance to employees pursuant
to the Target ESPP, of which 31,643 shares have been issued, (iii) 20,000 shares
of Series A Preferred Stock for issuance under the Rights Agreement, none of
which are issued and outstanding and (iv) 35,156 shares of Common Stock for
issuance upon the exercise of warrants, which warrants have an exercise price of
$8.00 per share and which warrants will not be exercised prior to the Closing
and will only be net exercised at the Closing; provided, however, that such
warrants must be net exercised only to the extent that such net issuance is
required in order to avoid approval of Acquiror's stockholders. Except as
expressly permitted by the terms of this Agreement, since January 23, 1997,
Target has not (i) issued or granted additional options under the Target Stock
Option Plans, or (ii) accepted contributions to or enrollments in the Target
ESPP. Except for (i) the rights created pursuant to this Agreement, the Stock
Option Agreement, the Target Stock Option Plans, the Target ESPP and the Rights
Agreement and (ii) the Target's right to repurchase any unvested shares under
 
                                      AA-6
<PAGE>   156
 
the Target Stock Option Plans, there are no other options, warrants, calls,
rights, commitments or agreements of any character to which Target is a party or
by which it is bound obligating Target to issue, deliver, sell, repurchase or
redeem, or cause to be issued, delivered, sold, repurchased or redeemed, any
shares of capital stock of Target or obligating Target to grant, extend,
accelerate the vesting of, change the price of, or otherwise amend or enter into
any such option, warrant, call, right, commitment or agreement. There are no
contracts, commitments or agreements relating to voting, purchase or sale of
Target's capital stock (i) between or among Target and any of its stockholders
and (ii) to Target's knowledge, between or among any of Target's stockholders,
except for the stockholders named in Schedule 5.7 of this Agreement. The terms
of the Target Stock Option Plans permit the outstanding options under those
Plans to be assumed by Acquiror as provided in Section 5.10 hereof, without the
consent or approval of the holders of those options, the Target stockholders, or
otherwise. The current "Purchase Interval" (as defined in the Target ESPP)
commenced under the Target ESPP on November 1, 1996 and will, together with the
current offering period under the Target ESPP, end upon the earlier of April 30,
1997 or the Effective Time as provided in this Agreement, and except for the
outstanding purchase rights held by participants in the current Purchase
Interval, there are no other purchase rights or options outstanding under the
Target ESPP. True and complete copies of all agreements and instruments relating
to or issued under the Target Stock Option Plans or Target ESPP have been made
available to Acquiror and such agreements and instruments have not been amended,
modified or supplemented, and there are no agreements to amend, modify or
supplement such agreements or instruments in any case from the form made
available to Acquiror.
 
     2.3  Authority.  Target has all requisite corporate power and authority to
enter into this Agreement and the Stock Option Agreement and to consummate the
transactions contemplated hereby and thereby. The execution and delivery of this
Agreement and the Stock Option Agreement and the consummation of the
transactions contemplated hereby and thereby have been duly authorized by all
necessary corporate action on the part of Target, subject only to the approval
of the Merger by Target's stockholders as contemplated by Section 6.1(a). Each
of this Agreement and the Stock Option Agreement has been duly executed and
delivered by Target and constitutes the valid and binding obligation of Target

enforceability may be limited by bankruptcy and other laws affecting the rights
and remedies of creditors generally and general principles of equity. Subject to
satisfaction of the conditions set forth in Article VI hereof, the execution and
delivery of this Agreement and the Stock Option Agreement by Target does not,
and the consummation of the transactions contemplated hereby will not, conflict
with, or result in any violation of, or default under (with or without notice or
lapse of time, or both), or give rise to a right of termination, cancellation or
acceleration of any obligation or loss of any benefit under (i) any provision of
the Certificate of Incorporation or Bylaws of Target, as amended, or (ii) any
material mortgage, indenture, lease, contract or other agreement or instrument
required to be filed with the Target SEC Documents (as defined in Section 2.4
hereof), permit, concession, franchise, license, judgment, order, decree,
statute, law, ordinance, rule or regulation applicable to Target or any of its
properties or assets, except where such conflict, violation, default,
termination, cancellation or acceleration with respect to the foregoing
provisions of (ii) would not have had a Material Adverse Effect on Target. To
the knowledge of Target, no consent, approval, order or authorization of, or
registration, declaration or filing with, any court, administrative agency or
commission or other governmental authority or instrumentality ("Governmental
Entity") is required by or with respect to Target in connection with the
execution and delivery of this Agreement, the Stock Option Agreement, or the
consummation of the transactions contemplated hereby and thereby, except for (i)
the filing of the Certificate of Merger as provided in Section 1.2, (ii) the
filing with the Securities and Exchange Commission (the "SEC") and the National
Association of Securities Dealers, Inc. (the "NASD") of the Proxy Statement (as
defined in Section 2.21) relating to the Target Stockholders' Meeting (as
defined in Section 2.21), (iii) such consents, approvals, orders,
authorizations, registrations, declarations and filings as may be required under
applicable state securities laws and the securities laws of any foreign country;
(iv) such filings as may be required under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended ("HSR"); and (v) such other consents,
authorizations, filings, approvals and registrations which, if not
 
                                      AA-7
<PAGE>   157
 
obtained or made, would not have a Material Adverse Effect on Target and would
not prevent, or materially alter or delay any of the transactions contemplated
by this Agreement or the Stock Option Agreement.
 
     2.4  SEC Documents; Financial Statements.  Target has furnished or made
available to Acquiror a true and complete copy of each statement, report,
registration statement (with the prospectus in the form filed pursuant to Rule
424(b) of the Securities Act of 1933, as amended (the "Securities Act")),
definitive proxy statement and other filing filed with the SEC by Target since
November 1, 1995, and, prior to the Effective Time, Target will have furnished
Acquiror with true and complete copies of any additional documents filed with
the SEC by Target prior to the Effective Time (collectively, the "Target SEC
Documents"). In addition, Target has made available to Acquiror all exhibits to
the Target SEC Documents filed prior to the date hereof, and will promptly make
available to Acquiror all exhibits to any additional Target SEC Documents filed
prior to the Effective Time. All documents required to be filed as exhibits to
the Target SEC Documents have been so filed, and all material contracts so filed
as exhibits are in full force and effect, except those which have expired in
accordance with their terms, and Target is not in default thereunder, except
where any such default has not resulted in and is not expected to result in any
Material Adverse Effect on Target. As of their respective filing dates, the
Target SEC Documents complied in all material respects with the requirements of
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the
Securities Act, and none of the Target SEC Documents contained any untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary to make the statements made therein, in light of the
circumstances in which they were made, not misleading, except to the extent
corrected by a subsequently filed Target SEC Document. The financial statements
of Target, including the notes thereto, included in the Target SEC Documents
(the "Target Financial Statements") were complete and correct in all material
respects as of their respective dates, complied as to form in all material
respects with applicable accounting requirements and with the published rules
and regulations of the SEC with respect thereto as of their respective dates,
and have been prepared in accordance with generally accepted accounting
principles applied on a basis consistent throughout the periods indicated and
consistent with each other (except as may be indicated in the notes thereto or,
in the case of unaudited statements included in Quarterly Reports on Form 10-Q,
as permitted by Form 10-Q of the SEC). The Target Financial Statements fairly
present the financial condition and operating results of Target at the dates and
during the periods indicated therein (subject, in the case of unaudited
statements, to normal, recurring year-end adjustments) in all material respects.
There has been no material change in Target accounting policies except as
required to be described in the notes to the Target Financial Statements.
 
     2.5  Absence of Certain Changes.  Since December 31, 1996 (the "Target
Balance Sheet Date"), Target has conducted its business in the ordinary course
consistent with past practice and there has not occurred: (i) any change, event
or condition (whether or not covered by insurance) that has resulted in, or
might reasonably be expected to result in, a Material Adverse Effect to Target;
(ii) any acquisition, sale or transfer of any material asset of Target other
than in the ordinary course of business and consistent with past practice; (iii)

or payment of a dividend or other distribution with respect to the shares of
Target, or any direct or indirect redemption, purchase or other acquisition by
Target of any of its shares of capital stock other than the repurchase of any
shares of its capital stock from former employees, directors or consultants in
accordance with agreements providing for the repurchase of shares or (v) any
material contract entered into by Target, other than in the ordinary course of

amendment or termination of, or to Target's knowledge, default under, any
material contract to which Target is a party or by which it is bound which could
result in a Material Adverse Effect on Target.

     2.6  Absence of Undisclosed Liabilities.  Target has no material
obligations or liabilities (matured or unmatured, fixed or contingent) other
than (i) those set forth or adequately provided for in the Balance Sheet for the
period ended December 31, 1996 attached hereto as Schedule 2.6 (the "Target
Balance Sheet"), (ii) those not required to be set forth in the Target Balance
Sheet under generally accepted accounting principles, (iii) those incurred in
the ordinary course of business since the Target Balance Sheet Date and
consistent with past practice; and (iv) those incurred in connection with the
execution of this Agreement.
 
     2.7  Litigation.  There is no private or governmental action, suit,
proceeding, claim, arbitration or investigation pending before any agency, court
or tribunal, foreign or domestic, or, to the knowledge of Target, threatened
against Target or any of its properties or any of its officers or directors (in
their capacities as such) that, individually or in the aggregate, could
reasonably be expected to have a Material Adverse Effect on Target. There is no
judgment, decree or order against Target, or, to the knowledge of Target, any of
its directors or officers (in their capacities as such), that could prevent,
enjoin, materially alter or materially delay any of the transactions
contemplated by this Agreement, or that could reasonably be expected to have a
Material Adverse Effect on Target.
 
     2.8  Restrictions on Business Activities.  There is no material agreement,
judgment, injunction, order or decree binding upon Target which has the effect
of prohibiting or materially impairing any current or future business practice
of Target as presently contemplated, any acquisition of property by Target or
the conduct of business by Target as currently conducted or as proposed to be
conducted prior to the Effective Time by Target.
 
     2.9  Governmental Authorization.  Target has obtained each federal, state,
county, local or foreign governmental consent, license, permit, grant, or other
authorization of a Governmental Entity (i) pursuant to which Target currently
operates or holds any interest in any of its properties or (ii) that is required
for the operation of Target's business or the holding of any such interest ((i)
and (ii) herein collectively called "Target Authorizations"), and all of such
Target Authorizations are in full force and effect, except where the failure to
obtain or have any of such Target Authorizations could not reasonably be
expected to have a Material Adverse Effect on Target.
 
     2.10  Title to Property.  Target has good and valid title to all of its
properties, interests in properties and assets, real and personal, reflected in
the Target Balance Sheet or acquired after the Target Balance Sheet Date (except
properties, interests in properties and assets sold or otherwise disposed of
since the Target Balance Sheet Date in the ordinary course of business), or in
the case of leased properties and assets, valid leasehold interests in, free and
clear of all mortgages, liens, pledges, charges or encumbrances of any kind or
character, except (i) the lien of current taxes not yet due and payable, (ii)
such imperfections of title, liens and easements as do not and will not
materially detract from or interfere with the use of the properties subject
thereto or affected thereby, or otherwise materially impair business operations
involving such properties, (iii) liens securing debt which is reflected on the
Target Balance Sheet or in the Target SEC Documents or (iv) those which would
not have a Material Adverse Effect on Target. The property and equipment of
Target that are used in the operation of its business are adequate for the
conduct of the business of Target consistent with its past practice. All
properties used in the operations of Target are reflected in the Target Balance
Sheet to the extent generally accepted accounting principles require the same to
be reflected. Schedule 2.10 identifies each parcel of real property owned or
leased by Target.
 
     2.11  Intellectual Property.
 
          (a) Target owns, or is licensed or otherwise possesses legally
     enforceable rights to use all patents, trademarks, trade names, service
     marks, copyrights, and any applications therefor, schematics, technology,
     know-how, trade secrets, inventory, algorithms, processes, computer
     software programs or applications (in both source code and object code
     form), and tangible or intangible proprietary information or material
     ("Intellectual Property") that are used or proposed to be used in the
     business of Target as currently conducted or as proposed to be conducted
     prior to

<PAGE>   159
 
     the Effective Time by Target, except to the extent that the failure to have
     such rights have not had and would not reasonably be expected to have a
     Material Adverse Effect on Target.
 
          (b) Schedule 2.11 lists (i) all patents and patent applications and
     all registered and unregistered trademarks, trade names and service marks,
     and registered copyrights, which Target considers to be material to its
     business and included in the Intellectual Property, including the
     jurisdictions in which each such Intellectual Property right has been
     issued or registered or in which any application for such issuance and
     registration has been filed, (ii) all licenses, sublicenses and other
     agreements as to which Target is a party (except customer or end-user
     licenses entered into in the ordinary course of business) and which Target
     considers to be material to its business and pursuant to which any person
     is authorized to use any Intellectual Property, and (iii) all licenses,
     sublicenses and other agreements as to which Target is a party and pursuant
     to which Target is authorized to use any third party patents, trademarks or
     copyrights, including software ("Third Party Intellectual Property Rights")
     which are incorporated in, are, or form a part of any Target product that
     is material to its business.
 
          (c) To Target's knowledge, there is no unauthorized use, disclosure,
     infringement or misappropriation of any Intellectual Property rights of
     Target, any trade secret material to Target, or any Intellectual Property
     right of any third party to the extent licensed by or through Target, by
     any third party, including any employee or former employee of Target.
     Target has not entered into any agreement to indemnify any other person
     against any charge of infringement of any Intellectual Property, other than
     indemnification provisions contained in purchase orders or customer
     agreements arising in the ordinary course of business.
 
          (d) All patents, registered trademarks, registered service marks and
     registered copyrights held by Target and material to the business of Target
     as currently conducted and as proposed to be conducted prior to the
     Effective Time are valid and subsisting. Target (i) has not been sued in
     any suit, action or proceeding which involves a material claim of
     infringement of any patents, trademarks, service marks, copyrights or
     violation of any trade secret or other proprietary right of any third party
     and (ii) has not brought any action, suit or proceeding for infringement of
     Intellectual Property or breach of any license or agreement involving
     Intellectual Property against any third party. The manufacture, marketing,
     licensing or sale of Target's products does not infringe any patent,
     registered trademark, registered service mark, registered copyright, trade
     secret or other proprietary right of any third party, except where such
     infringement would not have a Material Adverse Effect on Target.
 
          (e) Target has taken reasonable steps to protect and preserve the
     confidentiality of all Intellectual Property not otherwise protected by
     patents, or patent applications or copyright and which constitutes a trade
     secret of Target ("Confidential Information").

     2.14  Employee Benefit Plans.
 
          (a) Schedule 2.14 lists, with respect to Target, any subsidiary of
     Target and any trade or business (whether or not incorporated) which is
     treated as a single employer with Target (an "ERISA Affiliate") within the
     meaning of Section 414(b), (c), (m) or (o) of the Code, (i) all material
     employee benefit plans (as defined in Section 3(3) of the Employee
     Retirement Income Security Act of 1974, as amended ("ERISA")) in excess of
     $50,000, (ii) each loan to a non-officer employee in excess of $50,000,
     loans to officers and directors and any stock option, stock purchase,
     phantom stock, stock appreciation right, supplemental retirement,
     severance, sabbatical, medical, dental, vision care, disability, employee
     relocation, cafeteria benefit (Code section 125) or dependent care (Code
     Section 129), life insurance or accident insurance plans, programs or
     arrangements, (iii) all bonus, pension, profit sharing, savings, deferred
     compensation or incentive plans, programs or arrangements, (iv) other
     fringe or employee benefit plans, programs or arrangements that apply to
     senior management of Target and that do not generally apply to all
     employees, and (v) any current or former employment or executive
     compensation or severance agreements, written or otherwise, as to which
     unsatisfied obligations of Target of greater than $50,000 remain for the
     benefit of, or relating to, any present or former employee, consultant or
     director of Target (together, the "Target Employee Plans").
 
          (b) Target has furnished to Acquiror a copy of each of the Target
     Employee Plans and related plan documents (including trust documents,
     insurance policies or contracts, employee booklets, summary plan
     descriptions and other authorizing documents, and, to the extent still in
     its possession, any material employee communications relating thereto) and
     has, with respect to each Target Employee Plan which is subject to ERISA
     reporting requirements, provided copies of the Form 5500 reports filed for
     the last three plan years. Any Target Employee Plan intended to be
     qualified under Section 401(a) of the Code has either obtained from the
     Internal Revenue Service a favorable determination letter as to its
     qualified status under the Code, including all amendments to the Code
     effected by the Tax Reform Act of 1986 and subsequent legislation, or has
     applied to the Internal Revenue Service for such a determination letter
     prior to the expiration of the requisite period under applicable Treasury
     Regulations or Internal Revenue Service pronouncements in which to apply
     for such determination letter and to make any amendments necessary to
     obtain a favorable determination. Target has also furnished Acquiror with
     the most recent Internal Revenue Service determination letter issued with
     respect to each such Target Employee Plan, and nothing has occurred since
     the issuance of each such letter which could reasonably be expected to
     cause the loss of the tax-qualified status of any Target Employee Plan
     subject to Code Section 401(a).
 
          (c) (i) None of the Target Employee Plans promises or provides retiree
     medical or other retiree welfare benefits to any person; (ii) there has
     been no "prohibited transaction," as such term is defined in Section 406 of
     ERISA and Section 4975 of the Code, with respect to any Target Employee
     Plan, which could reasonably be expected to have, in the aggregate, a
     Material Adverse Effect; (iii) each Target Employee Plan has been
     administered in accordance with its terms and in compliance with the
     requirements prescribed by any and all statutes, rules and regulations
     (including ERISA and the Code), except as would not have, in the aggregate,
     a Material Adverse Effect, and Target and each subsidiary or ERISA
     Affiliate have performed all obligations required to be performed by them
     under, are not in any respect in default under or violation of, and have no
     knowledge of any default or violation by any other party to, any of the
     Target Employee Plans, which default or violation could reasonably be
     expected to have a Material Adverse Effect on Target; (iv) neither Target
     nor any subsidiary or ERISA Affiliate is subject to any liability or
     penalty under Sections 4976 through 4980 of the Code or Title I of ERISA
     with respect to any of the Target Employee Plans; (v) all material
     contributions required to be made by Target or any subsidiary or ERISA
     Affiliate to any Target Employee Plan have been made on or before their due
     dates and a reasonable amount has been accrued for contributions to each
     Target Employee Plan for the current plan years; (vi) with respect to each
     Target Employee Plan, no "reportable event" within the meaning of Section
     4043 of ERISA (excluding any such event for which the thirty (30)
 
                                      AA-12
<PAGE>   162
 
     day notice requirement has been waived under the regulations to Section
     4043 of ERISA) nor any event described in Section 4062, 4063 or 4041 or
     ERISA has occurred; and (vii) no Target Employee Plan is covered by, and
     neither Target nor any subsidiary or ERISA Affiliate has incurred or
     expects to incur any liability under, Title IV of ERISA or Section 412 of
     the Code. With respect to each Target Employee Plan subject to ERISA as
     either an employee pension plan within the meaning of Section 3(2) of ERISA
     or an employee welfare benefit plan within the meaning of Section 3(1) of
     ERISA, Target has prepared in good faith and timely filed all requisite
     governmental reports (which were true and correct in all material respects
     as of the date filed) and has properly and timely filed and distributed or
     posted all notices and reports to employees required to be filed,
     distributed or posted with respect to each such Target Employee Plan,
     except where the failure to do so would not result in a Material Adverse
     Effect on Target. No suit, administrative proceeding, action or other
     litigation has been brought, or to the best knowledge of Target is
     threatened, against or with respect to any such Target Employee Plan,
     including any audit or inquiry by the IRS or United States Department of
     Labor. Neither Target nor any Target subsidiary or other ERISA Affiliate is
     a party to, or has made any contribution to or otherwise incurred any
     obligation under, any "multiemployer plan" as defined in Section 3(37) of
     ERISA.
 
     (d) With respect to each Target Employee Plan, Target and each of its
United States subsidiaries have complied with (i) the applicable health care
continuation and notice provisions of the Consolidated Omnibus Budget
Reconciliation Act of 1985 ("COBRA") and the proposed regulations thereunder and
(ii) the applicable requirements of the Family and Medical Leave Act of 1993 and
the regulations thereunder, except to the extent that such failure to comply
would not, in the aggregate, have a Material Adverse Effect.
 
     (e) The consummation of the transactions contemplated by this Agreement
will not (i) entitle any current or former employee or other service provider of
Target, any Target subsidiary or any other ERISA Affiliate to severance benefits
or any other payment, except as expressly provided in this Agreement, or (ii)
accelerate the time of payment or vesting, or increase the amount of
compensation due any such employee or service provider.
 
     (f) There has been no amendment to, written interpretation or announcement
(whether or not written) by Target, any Target subsidiary or other ERISA
Affiliate relating to, or change in participation or coverage under, any Target
Employee Plan which would materially increase the expense of maintaining such
Plan above the level of expense incurred with respect to that Plan for the most
recent fiscal year included in Target's financial statements.
 
     2.15  Certain Agreements Affected by the Merger.  Neither the execution and
delivery of this Agreement nor the consummation of the transaction contemplated
hereby will (i) result in any payment (including, without limitation, severance,
unemployment compensation, golden parachute, bonus or otherwise) becoming due to
any director or employee of Target, (ii) materially increase any benefits
otherwise payable by Target or (iii) result in the acceleration of the time of
payment or vesting of any such benefits.
 
     2.16  Employee Matters.  Target is in compliance in all respects with all
currently applicable laws and regulations respecting employment, discrimination
in employment, terms and conditions of employment, wages, hours and occupational
safety and health and employment practices, and is not engaged in any unfair
labor practice, except where the failure to be in compliance or the engagement
in such unfair labor practices would not have a Material Adverse Effect on
Target. There are no pending claims against Target under any workers
compensation plan or policy or for long term disability which would have a
Material Adverse Effect on Target. Target has no obligations under COBRA with
respect to any former employees or qualifying beneficiaries thereunder, except
for obligations that would not have a Material Adverse Effect on Target. There
are no controversies pending or, to the knowledge of Target, threatened, between
Target and any of its employees, which controversies would have a Material
Adverse Effect on Target. Target is not a party to any collective bargaining
agreement or other labor union contract nor does Target know of any activities
or proceedings of any labor union to organize any such employees.

violations or failures to comply as would not have a Material Adverse Effect on
Target.
 
     2.20  Brokers' and Finders' Fees.  Target has not incurred, nor will it

of the Delaware Law applicable to a "business combination" (as defined in
Section 203) will not apply to the execution, delivery or performance of this
Agreement or the Stock Option Agreement or the consummation of the Merger or the
other transactions contemplated by this Agreement or by the Stock Option
Agreement.
 
     2.26  Target Rights Agreement.  The Board of Directors of Target has taken
all necessary action to amend the Rights Agreement so that neither the execution
of this Agreement nor the consummation of the transactions contemplated
hereunder (including any exercise of the Target Option (as such term is defined
in the Stock Option Agreement)) will cause Acquiror or Merger Sub to become an
Acquiring Person (as such term is defined in the Rights Agreement) or the
occurrence of a Stock Acquisition Date or Distribution Date (as such terms are
defined in the Rights Agreement) and further to provide that, at the Effective
Time, the Rights issued pursuant to the Rights Agreement will expire.
 
     2.27  Foreign Corrupt Practices Act.  Target has not made, offered or
agreed to offer anything of value to any government official, political party or
candidate for government office nor has it otherwise taken any action which
would cause Target to be in violation of the Foreign Corrupt Practices Act of
1977.
 
     2.28  Government Regulation.  To Target's knowledge, each 510(k) premarket
notification ("510(k)") and premarket approval application ("PMA") filed with
the United States Food and Drug Administration (the "FDA") with respect to
Target's products complies in all material respects with the rules and
regulations of the FDA regarding the filing of a 510(k) or PMA, as applicable.
Each such 510(k) and PMA includes results of testing and no material adverse
comments with respect thereto have been received by Target from the FDA. Target
reasonably believes that the data submitted as part of each 510(k) and PMA is
sufficient to support FDA approval of such 510(k) or PMA; provided, however,
that notwithstanding the foregoing, Target makes no representation to the effect
that it will not file a supplement to such 510(k) or PMA or that such 510(k) or
PMA will be approved by the FDA or contains all of the information which the FDA
requires or will require in its consideration thereof.
 
     2.29  Representations Complete.  None of the representations or warranties
made by Target herein or in any Schedule hereto, including the Target Disclosure
Schedule, or certificate furnished by Target pursuant to this Agreement, or the
Target SEC Documents, when all such documents are read together in their
entirety, contains or will contain at the Effective Time any untrue statement of
a material fact, or omits or will omit at the Effective Time to state any
material fact necessary in order to make the statements contained herein or
therein, in the light of the circumstances under which made, not misleading.

of the Exchange Act and the Securities Act, and none of the Acquiror SEC
Documents contained any untrue statement of a material fact or omitted to state
a material fact required to be stated therein or necessary to make the
statements made therein, in light of the circumstances in which they were made,
not misleading, except to the extent corrected by a subsequently filed Acquiror
SEC Document. The financial statements of Acquiror, including the notes thereto,
included in the Acquiror SEC Documents (the "Acquiror Financial Statements")
were complete and correct in all material respects as of their respective dates,
complied as to form in all material respects with applicable accounting
requirements and with the published rules and regulations of the SEC with

consistent throughout the periods indicated and consistent with each other

of the SEC). The Acquiror Financial Statements fairly present the consolidated
financial condition and operating results of Acquiror and its subsidiaries at
the dates and during the periods indicated therein (subject, in the case of

respects. There has been no change in Acquiror accounting policies except as

or condition (whether or not covered by insurance) that has resulted in, or
might reasonably be expected to result in, a Material Adverse Effect to

Acquiror or any material revaluation by Acquiror of any of its assets; (iv) any
declaration, setting aside, or payment of a dividend or other distribution with
respect to the shares of Acquiror, or any direct or indirect redemption,
purchase or other acquisition by Acquiror of any of its shares of capital stock

employees, directors or consultants in accordance with agreements providing for
the repurchase of shares; or (v) any material contract entered into by Acquiror,

knowledge, default under, any material contract to which Acquiror is a party or
by which it is bound which could result in a Material Adverse Effect on
Acquiror.
 
     3.6  Absence of Undisclosed Liabilities.  Acquiror has no material
obligations or liabilities (matured or unmatured, fixed or contingent) other

or tribunal, foreign or domestic, or, to the knowledge of Acquiror or any of its
subsidiaries, threatened against Acquiror or any of its subsidiaries or any of
their respective properties or any of their respective officers or directors (in
their capacities as such) that, individually or in the aggregate, could
reasonably be expected to have a Material Adverse Effect on Acquiror. There is
no judgment, decree or order against Acquiror or any of its subsidiaries or, to
the knowledge of Acquiror or any of its subsidiaries, any of their respective

materially alter or materially delay any of the transactions contemplated by
this Agreement, or that could reasonably be expected to have a Material Adverse
Effect on Acquiror.

operation of Acquiror's or any of its subsidiaries' business or the holding of
any such interest ((i) and (ii) herein collectively called "Acquiror
Authorizations"), and all of such Acquiror Authorizations are in full force and
effect, except where the failure to obtain or have any of such Acquiror
Authorizations could not reasonably be expected to have a Material Adverse
Effect on Acquiror.
 
     3.10  Compliance With Laws.  Each of Acquiror and its subsidiaries has
complied with, are not in violation of, and have not received any notices of
violation with respect to, any federal, state, local or foreign statute, law or

operation of its business, except for such violations or failures to comply as
would not have a Material Adverse Effect on Acquiror.
 
     3.11  Broker's and Finders' Fees.  Acquiror has not incurred, nor will it
incur, directly or indirectly, any liability for brokerage or finders' fees or

     to perform its covenants hereunder.
 
     4.3  No Solicitation.  Target and the officers, directors, employees or
other agents of Target will not, directly or indirectly, (i) take any action to
solicit, initiate or encourage any Takeover Proposal (defined below) or (ii)
subject to the terms of the immediately following sentence, engage in
negotiations with, or disclose any nonpublic information relating to Target to,
or afford access to the properties, books or records of Target to, any person
that has advised Target that it may be considering making, or that has made, a
Takeover Proposal; provided, nothing herein shall prohibit Target's Board of
Directors from taking and disclosing to Target's stockholders a position with
respect to a tender offer pursuant to Rules 14d-9 and 14e-2 promulgated under
the Exchange Act. Notwithstanding the immediately preceding sentence, if an
unsolicited Takeover Proposal, or an unsolicited written expression of interest
that can reasonably be expected to lead to a Takeover Proposal, shall be
received by the Board of Directors of Target, then, to the extent the Board of
Directors of Target believes in good faith (after consultation with its
financial advisor) that such Takeover Proposal would, if consummated, result in
a transaction more favorable to Target's stockholders from a financial point of
view than the transaction contemplated by the Agreement (any such more favorable
Takeover Proposal being referred to in this Agreement as a "Superior Proposal")
and the Board of Directors of Target determines in good faith after consultation
with outside legal counsel that it is necessary for the Board of Directors of
Target to comply with its fiduciary duties to stockholders under applicable law,
Target and its officers, directors, employees, investment bankers, financial
advisors, attorneys, accountants and other representatives retained by it may
furnish in connection therewith information and take such other actions as are
consistent with the fiduciary obligations of Target's Board of Directors, and
such actions shall not be considered a breach of this Section 4.3 or any other
provisions of this Agreement, provided that in each such event Target notifies
Acquiror of such determination by the Target Board of Directors and provides
Acquiror with a true and complete copy of the Superior Proposal received from
such third party, if the Superior Proposal is in writing, or a complete written
summary thereof, if it is not in writing, and provides Acquiror with all
documents containing or referring to non-public information of Target that are
supplied to such third party; provided, further, that (A) the Board of Directors
of Target has determined, with the advice of Target's investment bankers, that
such third party is capable of making a Superior Proposal upon satisfactory
completion of such third party's review of the information supplied by Target,
(B) the third party has made a written expression of interest that can
reasonably be expected to lead to a Superior Proposal, (C) Target may not
provide any non-public information to any such third party if it has not prior
to the date thereof provided such information to Acquiror or Acquiror's
representatives, and (D) Target provides such non-public information pursuant to
a non-disclosure agreement at least as restrictive as the Confidentiality
Agreement (as defined in Section 5.4); provided, however, that Target shall not,
and shall not permit any of its officers, directors, employees or other
representatives to agree to or endorse any Takeover Proposal unless Target shall
have terminated this Agreement pursuant to Section 7.1(e) and paid Acquiror all
amounts payable to Acquiror pursuant to Section 7.3(b). Target will promptly
notify Acquiror after receipt of any Takeover Proposal or any notice that any
person is considering making a Takeover Proposal or any request for non-public
information relating to Target or for access to the properties, books or records
of Target by any person that has advised Target that it may be considering
making, or that has made, a Takeover Proposal and will keep Acquiror fully
informed of the status as well as the material details of any such Takeover
Proposal notice, request or any correspondence or communications related thereto
and shall provide Acquiror with a true and complete copy of such Takeover
Proposal notice or request or correspondence or communications related thereto,
if it is in writing, or a complete written summary thereof, if it is not in
writing. For purposes of this Agreement,

"Takeover Proposal" means any offer or proposal for, or any indication of
interest in, a merger or other business combination involving Target or the
acquisition of any significant equity interest in, or a significant portion of
the assets of, Target, other than the transactions contemplated by this
Agreement.

     5.1  Proxy Statement/Prospectus; Registration Statement.  As promptly as
practicable after the execution of this Agreement, Target and Acquiror shall

reasonable efforts to cause the Registration Statement to become effective as
soon thereafter as practicable. Subject to the provisions of Section 4.3, the
Proxy Statement shall include the recommendation of the Board of Directors of
Target in favor of the Merger; provided that such recommendation may not be
included or may be withdrawn if previously included if Target's Board of
Directors believes in good faith that a Superior Proposal has been made and
shall determine that to include such recommendation or not withdraw such
recommendation if previously included would constitute a breach of the Board's
fiduciary duty under applicable law.
 
     5.2  Meeting of Stockholders.  Target shall promptly after the date hereof
take all action necessary in accordance with Delaware Law and its Certificate of
Incorporation and Bylaws to convene the Target Stockholders' Meeting within 45
days of the Registration Statements being declared effective by the SEC. Target
shall consult with Acquiror regarding the date of the Target Stockholders'
Meeting and use all reasonable efforts and shall not postpone or adjourn (other
than for the absence of a quorum) the Target Stockholders' Meeting without the
consent of Acquiror. Subject to Section 5.1, Target shall use its best efforts
to solicit from stockholders of Target proxies in favor of the Merger and shall
take all other action necessary or advisable to secure the vote or consent of
stockholders required to effect the Merger.
 
     5.3  Access to Information.
 
          (a) Target shall afford Acquiror and its accountants, counsel and
     other representatives, reasonable access during normal business hours
     during the period prior to the Effective Time to (i) all of Target's
     properties, books, contracts, commitments and records, and (ii) all other
     information concerning the business, properties and personnel of Target as
     Acquiror may reasonably request. Target agrees to provide to Acquiror and
     its accountants, counsel and other representatives copies of regularly
     prepared internal financial statements promptly upon request. Acquiror
     shall afford Target and its accountants, counsel and other representatives,
     reasonable access during normal business hours during the period prior to

     properties, books, contracts, commitments and records, and (ii) all other
     information concerning the business, properties and personnel of Acquiror
     and its subsidiaries as Target may reasonably request. Acquiror agrees to
     provide to Target and its accountants, counsel and other representatives
     copies of regularly prepared internal financial statements promptly upon
     request.
 
          (b) Subject to compliance with applicable law, from the date hereof
     until the Effective Time, each of Acquiror and Target shall confer on a
     regular and frequent basis with one or more representatives of the other
     party to report operational matters of materiality and the general status
     of ongoing operations of Acquiror, Target and, to Acquiror's knowledge, VC.

<PAGE>   174
 
          (c) No information or knowledge obtained in any investigation pursuant
     to this Section 5.3 shall affect or be deemed to modify any representation
     or warranty contained herein or the conditions to the obligations of the
     parties to consummate the Merger.
 
     5.4  Confidentiality.  The parties acknowledge that each of Acquiror and
Target have previously executed a non-disclosure agreement dated January 3, 1997
(the "Confidentiality Agreement"), which Confidentiality Agreement shall
continue in full force and effect in accordance with its terms.
 
     5.5  Public Disclosure.  Unless otherwise permitted by this Agreement,
Acquiror and Target shall consult with each other before issuing any press
release or otherwise making any public statement or making any other public (or
non-confidential) disclosure (whether or not in response to an inquiry)
regarding the terms of this Agreement and the transactions contemplated hereby,
and neither shall issue any such press release or make any such statement or
disclosure without the prior approval of the other (which approval shall not be
unreasonably withheld), except as may be required by law, or in exercise of the
fiduciary duties of the Board of Directors, or by obligations pursuant to any
listing agreement with any national securities exchange or with the NASD.
 
     5.6  Consents; Cooperation.
 
          (a) Each of Acquiror and Target shall promptly apply for or otherwise
     seek, and use its best efforts to obtain, all consents and approvals
     required to be obtained by it for the consummation of the Merger, including
     those required under HSR, and shall use its reasonable efforts to obtain
     all necessary consents, waivers and approvals under any of its material
     contracts in connection with the Merger for the assignment thereof or
     otherwise. The parties hereto will consult and cooperate with one another,
     and consider in good faith the views of one another, in connection with any
     analyses, appearances, presentations, memoranda, briefs, arguments,
     opinions and proposals made or submitted by or on behalf of any party
     hereto in connection with proceedings under or relating to HSR or any other
     federal or state antitrust or fair trade law.
 
          (b) Each of Acquiror and Target shall use all reasonable efforts to
     resolve such objections, if any, as may be asserted by any Governmental
     Entity with respect to the transactions contemplated by this Agreement
     under HSR, the Sherman Act, as amended, the Clayton Act, as amended, the
     Federal Trade Commission Act, as amended, and any other Federal, state or
     foreign statutes, rules, regulations, orders or decrees that are designed
     to prohibit, restrict or regulate actions having the purpose or effect of
     monopolization or restraint of trade (collectively, "Antitrust Laws"). In
     connection therewith, if any administrative or judicial action or
     proceeding is instituted (or threatened to be instituted) challenging any
     transaction contemplated by this Agreement as violative of any Antitrust
     Law, each of Acquiror and Target shall cooperate and use all best efforts
     vigorously to contest and resist any such action or proceeding and to have
     vacated, lifted, reversed, or overturned any decree, judgment, injunction
     or other order, whether temporary, preliminary or permanent (each an
     "Order"), that is in effect and that prohibits, prevents, or restricts
     consummation of the Merger or any such other transactions, unless by mutual
     agreement Acquiror and Target decide that litigation is not in their
     respective best interests. Notwithstanding the provisions of the
     immediately preceding sentence, it is expressly understood and agreed that
     neither Acquiror nor Target shall have any obligation to litigate or
     contest any administrative or judicial action or proceeding or any Order
     beyond the earlier of (i) September 30, 1997, or (ii) the date of a ruling
     preliminary enjoining the Merger issued by a court of competent
     jurisdiction (the "Injunction Date"). Each of Acquiror and Target shall use
     all reasonable efforts to take such action as may be required to cause the
     expiration of the notice periods under the HSR or other Antitrust Laws with
     respect to such transactions as promptly as possible after the execution of
     this Agreement.
 
          (c) Notwithstanding anything to the contrary in Section 5.6(a) or (b),
     (i) neither Acquiror nor any of it subsidiaries shall be required to divest
     any of their respective businesses, product lines or assets, or to take or
     agree to take any other action or agree to any limitation that could
     reasonably be expected to have a Material Adverse Effect on Acquiror or of
     Acquiror combined
 
                                      AA-25
<PAGE>   175
 
     with the Surviving Corporation after the Effective Time and (ii) Target
     shall not be required to divest any of its business, product lines or
     assets, or to take or agree to take any other action or agree to any
     limitation that could reasonably be expected to have a Material Adverse
     Effect on Target.
 
     5.7  Voting Agreement.  Target shall use its best efforts, on behalf of
Acquiror and pursuant to the request of Acquiror, to cause each officer and
director of Target named in Schedule 5.7 to execute and deliver to Acquiror a
Voting Agreement substantially in the form of Exhibit B attached hereto
concurrent with the execution of this Agreement.
 
     5.8  Legal Requirements.  Each of Acquiror, Merger Sub and Target will, and
will cause their respective subsidiaries to, take all reasonable actions
necessary to comply promptly with all legal requirements which may be imposed on
them with respect to the consummation of the transactions contemplated by this
Agreement and will promptly cooperate with and furnish information to any party
hereto necessary in connection with any such requirements imposed upon such
other party in connection with the consummation of the transactions contemplated
by this Agreement and will take all reasonable actions necessary to obtain (and
will cooperate with the other parties hereto in obtaining) any consent,
approval, order or authorization of, or any registration, declaration or filing
with, any Governmental Entity or other person, required to be obtained or made
in connection with the taking of any action contemplated by this Agreement.
 
     5.9  Blue Sky Laws.  Acquiror shall take such steps as may be necessary to
comply with the securities and blue sky laws of all jurisdictions which are
applicable to the issuance of the Acquiror Common Stock in connection with the
Merger. Target shall use its best efforts to assist Acquiror as may be necessary
to comply with the securities and blue sky laws of all jurisdictions which are
applicable in connection with the issuance of Acquiror Common Stock in
connection with the Merger.
 
     5.10  Employee Benefit Plans.
 
          (a) Schedule 5.10 hereto sets forth a true and complete list as of the
     date hereof of all holders of outstanding options under the Target Stock
     Option Plans, including the number of shares of Target capital stock
     subject to each such option, the exercise price per share and the term of
     each such option. On the Closing Date, Target shall deliver to Acquiror an
     updated Schedule 5.10 hereto current as of such date. At the Effective
     Time, the Target Stock Option Plans and a portion of each outstanding
     option to purchase shares of Target Common Stock under the Target Stock
     Option Plans will be assumed and cashed out by Acquiror on the terms set
     forth in this paragraph (a) and paragraph (b) below. Each such option so
     assumed by Acquiror under this Agreement shall continue to have, and be
     subject to, the same terms and conditions set forth in the Target Stock
     Option Plans, immediately prior to the Effective Time, except that (i) such
     option will be exercisable for that number of whole shares of Acquiror
     Common Stock equal to the product of the number of shares of Target Common
     Stock that were issuable upon exercise of such option immediately prior to
     the Effective Time multiplied by the Stock Consideration Exchange Ratio (as
     defined in Section 1.6(a)(ii) hereof) and rounded down to the nearest whole
     number of shares of Acquiror Common Stock, (ii) the per share exercise
     price for the shares of Acquiror Common Stock issuable upon exercise of
     such assumed option will be equal to the quotient determined by dividing
     the exercise price per share of Target Common Stock at which such option
     was exercisable immediately prior to the Effective Time by the Conversion
     Ratio, rounded up to the nearest whole cent, and (iii) the option shall be
     fully and immediately exercisable for vested shares of Acquiror Common
     Stock. While there can be no assurances that the assumed options will be
     incentive stock options, the parties will use their reasonable efforts to
     effect the assumption in a manner calculated to ensure preservation of
     incentive stock option status for the assumed options. Within ten (10)
     business days after the Effective Time, Acquiror will issue to each person
     who, immediately prior to the Effective Time, was a holder of an
     outstanding option under the Target Stock Option Plans a document in form
     and substance satisfactory to Target evidencing the foregoing assumption of
     such option by Acquiror. For purposes of this Section 5.10, the Conversion
     Ratio shall be that
 
                                      AA-26
<PAGE>   176
 
     fraction, the numerator of which is the value of the Stock Consideration as
     of the Effective Time and the denominator of which is the value of the
     Merger Consideration (as valued pursuant to Section 1.6(a)) as of the
     Effective Time.
 
          (b) At the Effective Time, a payment shall be made with respect to
     each option assumed by Acquiror pursuant to paragraph (a) above. Such
     payment per option share shall be equal to the Cash Consideration and the
     VC Consideration payable per share of Target Common Stock under Section
     1.6(a) multiplied by the number of shares of Target Common Stock subject to
     the assumed option less the excess of (i) the aggregate option exercise
     price in effect for the option immediately prior to the Effective Time less
     (ii) the aggregate exercise price of such assumed option as determined
     immediately after the Effective Time as set forth in paragraph (a) above.
     Such consideration per option share shall be paid proportionately in Cash
     Consideration and VC Consideration, with the cash amount to be in the same
     ratio as the Cash Consideration payable per share of Target Common Stock
     bears to the total of the Cash Consideration and the VC Consideration, and
     the VC portion to be in the same ratio as the VC Consideration payable per
     share of Target Common Stock bears to the total of the Cash Consideration
     and the VC Consideration.
 
          (c) Outstanding purchase rights under the Target ESPP shall be
     exercised upon the earlier of (i) the next scheduled purchase date under
     the Target ESPP or (ii) immediately prior to the Effective Time, and each
     participant in the Target ESPP shall accordingly be issued shares of Target
     Common Stock at that time, and each share of Target Common Stock so issued
     shall be canceled and extinguished at the Effective Time and converted
     automatically into the right to receive the Merger Consideration payable
     per share of Target Common Stock. The Target ESPP shall terminate with such
     exercise date, and no purchase rights shall be subsequently granted or
     exercised under the Target ESPP. Target employees who otherwise meet the
     eligibility requirements for participation in the Acquiror Employee Stock
     Purchase Plan shall be eligible to begin payroll deductions under that plan
     as of the first entry date thereunder following the Effective Time.
 
          5.11  Letter of Acquiror's and Target's Accountants.
 
          (a) Acquiror shall use all reasonable efforts to cause to be delivered
     to Target a Procedures Letter of Acquiror's independent auditors, dated a
     date within two business days before the date on which the Registration
     Statements shall become effective and addressed to Target, in form
     reasonably satisfactory to Target and customary in scope and substance for
     letters delivered by independent public accountants in connection with
     registration statements similar to the Registration Statements.
 
          (b) Target shall use all reasonable efforts to cause to be delivered
     to Acquiror a Procedures Letter of Target's independent auditors, dated a
     date within two business days before the date on which the Registration
     Statements shall become effective and addressed to Acquiror, in form
     reasonably satisfactory to Acquiror and customary in scope and substance
     for letters delivered by independent public accountants in connection with
     registration statements similar to the Registration Statements.
 
          5.12  Indemnification.
 
          (a) After the Effective Time, Acquiror will, and will cause the
     Surviving Corporation to, indemnify and hold harmless the present and
     former officers, directors, employees and agents of Target (the
     "Indemnified Parties") in respect of acts or omissions occurring on or
     prior to the Effective Time to the full extent permitted by law and to the
     full extent provided under Target's Certificate of Incorporation and Bylaws
     or any indemnification agreement with Target officers and directors to
     which Target is a party, in each case in effect on the date hereof. Without
     limitation of the foregoing, in the event any such Indemnified Party is or
     becomes involved in any capacity in any action, proceeding or investigation
     in connection with any matter relating to this Agreement
 
                                      AA-27
<PAGE>   177
 
     or the transactions contemplated hereby occurring on or prior to the
     Effective Time, Acquiror shall or shall cause the Surviving Corporation to
     pay as incurred such Indemnified Party's reasonable legal and other
     expenses (including the cost of any investigation and preparation) incurred
     in connection therewith.
 
          (b) For four (4) years after the Effective Time, Acquiror will either
     (i) at all times maintain at least $100,000,000 in cash, marketable
     securities and unrestricted lines of credit to be available to indemnify
     the Indemnified Parties in accordance with Section 5.12(a) above, or (ii)
     cause the Surviving Corporation to use its best efforts to provide

     state securities laws in connection with the Merger shall be shared equally
     by Target and Acquiror.
 
          (b) In the event that (i) either Acquiror or Target shall terminate

     party, (iii) Acquiror shall terminate this Agreement pursuant to Section

     7.3(b)(iii)(A), a Trigger Event shall not be deemed to include the
     acquisition by any Person of securities representing 15% or more of Target

     shares at any meeting to consider any merger, consolidation, sale of
     substantial assets or other business combination or extraordinary
     transaction involving Target, (ii) making, or in any way participating in,
     any "solicitation" of "proxies" (as such terms are defined or used in

     Target (including, without limitation, any such solicitation subject to
     Rule 14a-11 under the Exchange Act) or seeking to advise or influence any
     Person with respect to the voting of any voting securities of Target, (iii)
     forming, joining or in any way participating in any "group" within the

     securities of Target or (iv) otherwise acting, alone or in concert with
     others, to seek control of Target or to seek to control or influence the
     management or policies of Target. As used herein, a "Trigger Event" shall
     occur if any Person acquires securities representing 15% or more, or
     commences a tender or exchange offer following the successful consummation
     of which the offeror and its affiliate would beneficially own securities
     representing 20% or more, of the voting power of Target.

     counsel) as Acquiror's sole remedy.

            AMENDMENT NO. 1 TO AGREEMENT AND PLAN OF REORGANIZATION
 
     THIS AMENDMENT NO. 1 to the Agreement and Plan of Reorganization (the
"Original Reorganization Agreement") dated January 26, 1997, by and among
Endosonics Corporation, a Delaware corporation ("Acquiror"), Cardiometrics,
Inc., a Delaware corporation ("Target"), and River Acquisition Corporation, a
Delaware corporation and a wholly-owned subsidiary of Acquiror ("Merger Sub"),
is made this 1st day of May, 1997, by and among Acquiror, Target and Merger Sub.
 
     WHEREAS, the parties hereto desire to amend the Original Reorganization
Agreement to clarify the intentions of the parties with respect to (i) the
consideration to be received by Target stockholders and (ii) the consideration
to be received by holders of warrants to purchase outstanding shares of Target
Common Stock; and
 
     WHEREAS, the parties hereto desire to amend the Original Reorganization
Agreement to revise the period during which outstanding purchase rights under
the Target ESPP may be exercised.
 
     NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:
 
     1.  Section 1.6 of the Original Reorganization Agreement is hereby amended
and replaced in its entirety with the following:
 
     "1.6  Effect on Capital Stock.  By virtue of the Merger and without any
action on the part of Merger Sub, Target or the holders of any of the following
securities:
 
          (a)  Conversion of Target Common Stock.  At the Effective Time, each
     share of Target Common Stock issued and outstanding immediately prior to
     the Effective Time (other than any shares of Target Common Stock to be
     canceled pursuant to Section 1.6(b) and shares, if any held by persons who
     have not voted such shares for approval of the Merger and with respect to
     which such persons shall become entitled to appraisal rights in accordance
     with Section 262 of the Delaware Law ("Dissenting Shares")) will be
     canceled and extinguished and be converted automatically into the right to
     receive:
 
             (i)  an amount in cash equal to $2.00 (the "Cash Consideration");
 
             (ii)  0.35 shares of Acquiror Common Stock (the "Stock
        Consideration" and the "Stock Consideration Exchange Ratio"); and
 
             (iii)  0.20 shares of VC Common Stock held of record by Acquiror as
        of the date hereof (the "VC Exchange Ratio"), subject to adjustment as
        set forth below (the "VC Consideration" and collectively with the Cash
        Consideration and Stock Consideration, the "Merger Consideration"). The
        VC Exchange Ratio shall be subject to increase such that based on the
        average of the closing prices of Acquiror Common Stock and the average
        of the closing prices of VC Common Stock for the ten trading days
        immediately preceding (and including) the third trading day prior to the
        Target Stockholders' Meeting, the Merger Consideration shall be equal to
        $9.00 (the "Price"); provided, however, that if based on such
        calculation the VC Exchange Ratio would be greater than .2636, the VC
        Exchange Ratio shall be .2636 (the "Floor"); provided further, that at
        Acquiror's option, in lieu of such increase of the VC Exchange Ratio,
        the Cash Consideration may be increased such that, based on the average
        of the closing prices of Acquiror Common Stock and the average of the
        closing prices of VC Common Stock for the ten trading days immediately
        preceding (and including) the third trading day prior to the Target
        Stockholders' Meeting, the Merger Consideration shall be equal to $9.00;
        provided further, however, that if, as a result of such increase in the
        Cash Consideration in lieu of an increase of the VC Exchange Ratio, the
        Cash Consideration would be greater than the sum of (A) $2.00 and (B)
        the product obtained by multiplying (x) .0636 by (y) the average of the
        closing prices of VC Common Stock for the ten trading days immediately
        preceding (and including) the third trading day prior to the Target
        Stockholders' Meeting (such sum referred to herein as the "Cash
        Consideration Limit"), then the Cash Consideration shall equal the Cash
        Consideration Limit; and provided further that, notwith-
 
                                      AA-37
<PAGE>   187
 
        standing the foregoing, the VC Exchange Ratio shall not be less than
        0.20 and the Cash Consideration shall not be less than $2.00.
 
          (b)  Cancellation of Target Common Stock Owned by Acquiror or
     Target.  At the Effective Time, all shares of Target Common Stock that are
     owned by Target as treasury stock and each share of Target Common Stock
     owned by Acquiror or any direct or indirect wholly-owned subsidiary of
     Acquiror or of Target immediately prior to the Effective Time shall be
     canceled and extinguished without any conversion thereof.
 
          (c)  Target Stock Option Plans.  Immediately prior to the Effective
     Time, each outstanding option under the Target 1985 Stock Option Plan, the
     Target 1995 Stock Option Plan and the Target 1995 Stock Incentive Plan
     (collectively, the "Target Stock Option Plans") shall vest in full and
     become exercisable for any or all of the shares of Target Common Stock at
     the time subject to that option, with such accelerated vesting to be
     conditioned, however, upon the actual consummation of the Merger. Each
     share of Target Common Stock acquired under the Target Option Plans through
     the exercise of an outstanding option effected immediately prior to the
     Effective Time shall be canceled and extinguished at the Effective Time and
     converted automatically into the right to receive the Merger Consideration
     payable per share of Target Common Stock. However, if the Merger is not
     consummated, the option exercise price paid for any shares of Target Common
     Stock purchased under the Target Option Plans on the basis of the
     acceleration provided under this Section 1.6(c) shall be refunded by
     Target, and the vesting schedule for those shares shall revert to the
     schedule in effect immediately prior to acceleration hereunder. Any options
     which remain outstanding under the Target Option Plans at the Effective
     Time shall be cancelled in accordance with the provisions of Section 5.10.
 
          (d)  Target Warrants.  At the Effective Time, each outstanding warrant
     to purchase shares of Target Common Stock (a "Target Warrant"), pursuant to
     its terms, will be assumed by Acquiror and upon payment of the same
     aggregate exercise price for such warrant prior to the Effective Time be
     exercisable for
 
             (i)  an amount in cash equal to the Cash Consideration (as adjusted
        pursuant to Section 1.6(a)(iii)) multiplied by the number of shares of
        Target Common Stock subject to such warrant immediately prior to the
        Effective Time;
 
             (ii)  that number of shares of Acquiror Common Stock equal to the
        Stock Consideration Exchange Ratio multiplied by the number of shares of
        Target Common Stock subject to such warrant immediately prior to the
        Effective Time and
 
             (iii)  that number of shares of VC Common Stock equal to the VC
        Exchange Ratio (as adjusted pursuant to Section 1.6(a)(iii)) multiplied
        by the number of shares of Target Common Stock subject to such warrant
        immediately prior to the Effective Time.
 
          (e)  Capital Stock of Merger Sub.  At the Effective Time, each share
     of Common Stock, $.0001 par value, of Merger Sub ("Merger Sub Common
     Stock") issued and outstanding immediately prior to the Effective Time
     shall be converted into and exchanged for one validly issued, fully paid
     and nonassessable share of Common Stock, $.0001 par value, of the Surviving
     Corporation. Each stock certificate of Merger Sub evidencing ownership of
     any such shares shall continue to evidence ownership of such shares of
     capital stock of the Surviving Corporation.
 
          (f)  Adjustments to Exchange Ratio.  The Stock Consideration Exchange
     Ratio, the VC Exchange Ratio, the Price, the Floor, the Cash Consideration
     and the Cash Consideration Limit shall be adjusted to reflect fully the
     effect of any stock split, reverse split, stock dividend (including any
     dividend or distribution of securities convertible into Acquiror Common
     Stock, Target Common Stock or VC Common Stock), reorganization,
     recapitalization or other like change with respect to Acquiror Common
     Stock, Target Common Stock or VC Common Stock occurring after the date
     hereof and prior to the Effective Time.

<PAGE>   188
 
          (g)  Fractional Shares.  No fraction of a share of Acquiror Common
     Stock or VC Common Stock shall be issued, but in lieu thereof each holder
     of shares of Target Common Stock who would otherwise be entitled to a
     fraction of a share of Acquiror Common Stock or VC Common Stock (after
     aggregating all fractional shares of Acquiror Common Stock or VC Common
     Stock to be received by such holder) shall receive from Acquiror an amount
     of cash (rounded to the nearest whole cent) equal to the product of (i)
     such fraction, multiplied by (ii) the average of the closing prices of a
     share of Acquiror Common Stock or VC Common Stock, as applicable, for the
     ten trading days immediately preceding (and including) the third trading
     day prior to the Target Stockholders' Meeting, as reported on the Nasdaq
     National Market.
 
          (h)  Appraisal Rights.  Any Dissenting Shares shall not be converted
     into the right to receive the consideration set forth in Section 1.6(a) but
     shall instead be converted into the right to receive such consideration as
     may be determined to be due with respect to such Dissenting Shares pursuant
     to Delaware Law. Target agrees that, except with the prior written consent
     of Acquiror, or as required under Delaware Law, it will not voluntarily
     make any payment with respect to, or settle or offer to settle, any demand
     with respect to Dissenting Shares. Each holder of Dissenting Shares
     ("Dissenting Stockholder") who, pursuant to the provisions of Delaware Law,
     becomes entitled to payment of the fair value for shares of Target Common
     Stock shall receive payment therefor (but only after the value therefor
     shall have been agreed upon or finally determined pursuant to such
     provisions). If, after the Effective Time, any Dissenting Shares shall lose
     their status as Dissenting Shares, Acquiror shall issue and deliver, upon
     surrender by such shareholder of certificate or certificates representing
     shares of Target Common Stock, the consideration to which such stockholder
     would otherwise be entitled under this Section 1.6 and the Certificate of
     Merger."
 
     2.  The penultimate sentence of Section 2.2 of the Original Reorganization
Agreement is hereby amended and replaced in its entirety with the following:
 
     "The current "Purchase Interval" (as defined in the Target ESPP) commenced
under the Target ESPP on May 1, 1997 and will, together with the current
offering period under the Target ESPP, end upon the earlier of October 31, 1997
or the Effective Time as provided in this Agreement, and except for the
outstanding purchase rights held by participants in the current Purchase
Interval, there are no other purchase rights or options outstanding under the
Target ESPP."
 
     3.  The penultimate sentence of Section 5.10(c) is hereby amended and
replaced in its entirety with the following: "The Target ESPP shall terminate
upon the earlier of the October 31, 1997 scheduled purchase date or immediately
prior to the Effective Time."
 
     4.  Exhibit A of the Original Reorganization Agreement is hereby amended
such that all references to the Original Reorganization Agreement shall be to
the Original Reorganization Agreement, as amended by this Amendment.
 
     5.  This Amendment may be executed in two or more counterparts, each of
which shall be deemed an original, but all of which together shall constitute
one and the same instrument.
 
     6.  Capitalized terms not otherwise defined herein shall have the meaning
given to them in the Original Reorganization Agreement.

            AMENDMENT NO. 2 TO AGREEMENT AND PLAN OF REORGANIZATION
 
     THIS AMENDMENT NO. 2 to the Agreement and Plan of Reorganization dated
January 26, 1997, by and among Endosonics Corporation, a Delaware corporation
("Acquiror"), Cardiometrics, Inc., a Delaware corporation ("Target"), and River
Acquisition Corporation, a Delaware corporation and a wholly-owned subsidiary of
Acquiror ("Merger Sub"), as amended on May 1, 1997 (the "Amended Reorganization
Agreement"), is made this 20th day of May, 1997, by and among Acquiror, Target
and Merger Sub.
 
     WHEREAS, the parties hereto desire to amend the Amended Reorganization
Agreement to reflect a new agreement with respect to the consideration to be
received by securityholders of Target.
 
     NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:
 
     1. Section 1.6 of the Amended Reorganization Agreement is hereby amended
and replaced in its entirety with the following:
 
     "1.6 Effect on Capital Stock. By virtue of the Merger and without any
action on the part of Merger Sub, Target or the holders of any of the following
securities:
 
          (a) Conversion of Target Common Stock. At the Effective Time, each
     share of Target Common Stock issued and outstanding immediately prior to
     the Effective Time (other than any shares of Target Common Stock to be
     canceled pursuant to Section 1.6(b) and shares, if any, held by persons who
     have not voted such shares for approval of the Merger and with respect to
     which such persons shall become entitled to appraisal rights in accordance
     with Section 262 of the Delaware Law ("Dissenting Shares")) will be
     canceled and extinguished and be converted automatically into the right to
     receive:
 
             (i) an amount in cash equal to $3.00 (the "Cash Consideration");
 
             (ii) 0.35 shares of Acquiror Common Stock (the "Stock
        Consideration" and the "Stock Consideration Exchange Ratio"); and
 
             (iii) 0.1364 shares of VC Common Stock held of record by Acquiror
        as of the date hereof (the "VC Exchange Ratio"), subject to adjustment
        as set forth below (the "VC Consideration" and collectively with the
        Cash Consideration and Stock Consideration, the "Merger Consideration").
        The VC Exchange Ratio shall be subject to increase such that based on
        the average of the closing prices of Acquiror Common Stock and the
        average of the closing prices of VC Common Stock for the ten trading
        days immediately preceding (and including) the third trading day prior
        to the Target Stockholders' Meeting, the Merger Consideration shall be
        equal to $8.00 (the "Price"); provided, however, that if based on such
        calculation the VC Exchange Ratio would be greater than .19, the VC
        Exchange Ratio shall be .19 (the "Floor"); and provided further that,
        notwithstanding the foregoing, the VC Exchange Ratio shall not be less
        than 0.1364.
 
          (b)  Cancellation of Target Common Stock Owned by Acquiror or
     Target. At the Effective Time, all shares of Target Common Stock that are
     owned by Target as treasury stock and each share of Target Common Stock
     owned by Acquiror or any direct or indirect wholly-owned subsidiary of
     Acquiror or of Target immediately prior to the Effective Time shall be
     canceled and extinguished without any conversion thereof.
 
          (c)  Target Stock Option Plans. Immediately prior to the Effective
     Time, each outstanding option under the Target 1985 Stock Option Plan, the
     Target 1995 Stock Option Plan and the Target 1995 Stock Incentive Plan
     (collectively, the "Target Stock Option Plans") shall vest in full and
     become exercisable for any or all of the shares of Target Common Stock at
     the time subject to that option, with such accelerated vesting to be
     conditioned, however, upon the actual consummation of the Merger. Each
     share of Target Common Stock acquired under the Target Option Plans through
     the exercise of an outstanding option effected immediately prior to the
     Effective Time
 
                                      AA-41
<PAGE>   191
 
     shall be canceled and extinguished at the Effective Time and converted
     automatically into the right to receive the Merger Consideration payable
     per share of Target Common Stock. However, if the Merger is not
     consummated, the option exercise price paid for any shares of Target Common
     Stock purchased under the Target Option Plans on the basis of the
     acceleration provided under this Section 1.6(c) shall be refunded by
     Target, and the vesting schedule for those shares shall revert to the
     schedule in effect immediately prior to acceleration hereunder. Any options
     which remain outstanding under the Target Option Plans at the Effective
     Time shall be cancelled in accordance with the provisions of Section 5.10.
 
          (d)  Target Warrants. At the Effective Time, each outstanding warrant
     to purchase shares of Target Common Stock (a "Target Warrant"), pursuant to
     its terms, will be assumed by Acquiror and upon payment of the same
     aggregate exercise price for such warrant prior to the Effective Time be
     exercisable for
 
             (i) an amount in cash equal to the Cash Consideration multiplied by
        the number of shares of Target Common Stock subject to such warrant
        immediately prior to the Effective Time;
 
             (ii) that number of shares of Acquiror Common Stock equal to the
        Stock Consideration Exchange Ratio multiplied by the number of shares of
        Target Common Stock subject to such warrant immediately prior to the
        Effective Time and
 
             (iii) that number of shares of VC Common Stock equal to the VC
        Exchange Ratio (as adjusted pursuant to Section 1.6(a)(iii)) multiplied
        by the number of shares of Target Common Stock subject to such warrant
        immediately prior to the Effective Time.
 
          (e) Capital Stock of Merger Sub. At the Effective Time, each share of
     Common Stock, $.0001 par value, of Merger Sub ("Merger Sub Common Stock")
     issued and outstanding immediately prior to the Effective Time shall be
     converted into and exchanged for one validly issued, fully paid and
     nonassessable share of Common Stock, $.0001 par value, of the Surviving
     Corporation. Each stock certificate of Merger Sub evidencing ownership of
     any such shares shall continue to evidence ownership of such shares of
     capital stock of the Surviving Corporation.
 
          (f) Adjustments to Exchange Ratio. The Stock Consideration Exchange
     Ratio, the VC Exchange Ratio, the Price, the Floor and the Cash
     Consideration shall be adjusted to reflect fully the effect of any stock
     split, reverse split, stock dividend (including any dividend or
     distribution of securities convertible into Acquiror Common Stock, Target
     Common Stock or VC Common Stock), reorganization, recapitalization or other
     like change with respect to Acquiror Common Stock, Target Common Stock or
     VC Common Stock occurring after the date hereof and prior to the Effective
     Time.
 
          (g) Fractional Shares. No fraction of a share of Acquiror Common Stock
     or VC Common Stock shall be issued, but in lieu thereof each holder of
     shares of Target Common Stock who would otherwise be entitled to a fraction
     of a share of Acquiror Common Stock or VC Common Stock (after aggregating
     all fractional shares of Acquiror Common Stock or VC Common Stock to be
     received by such holder) shall receive from Acquiror an amount of cash
     (rounded to the nearest whole cent) equal to the product of (i) such
     fraction, multiplied by (ii) the average of the closing prices of a share
     of Acquiror Common Stock or VC Common Stock, as applicable, for the ten
     trading days immediately preceding (and including) the third trading day
     prior to the Target Stockholders' Meeting, as reported on the Nasdaq
     National Market.
 
          (h) Appraisal Rights. Any Dissenting Shares shall not be converted
     into the right to receive the consideration set forth in Section 1.6(a) but
     shall instead be converted into the right to receive such consideration as
     may be determined to be due with respect to such Dissenting Shares pursuant
     to Delaware Law. Target agrees that, except with the prior written consent
     of Acquiror, or as required under Delaware Law, it will not voluntarily
     make any payment with respect to, or settle or offer to settle, any demand
     with respect to Dissenting Shares. Each holder of Dissenting Shares
     ("Dissenting Stockholder") who, pursuant to the provisions of Delaware Law,
     becomes
 
                                      AA-42
<PAGE>   192
 
     entitled to payment of the fair value for shares of Target Common Stock
     shall receive payment therefor (but only after the value therefor shall
     have been agreed upon or finally determined pursuant to such provisions).
     If, after the Effective Time, any Dissenting Shares shall lose their status
     as Dissenting Shares, Acquiror shall issue and deliver, upon surrender by
     such shareholder of certificate or certificates representing shares of
     Target Common Stock, the consideration to which such stockholder would
     otherwise be entitled under this Section 1.6 and the Certificate of
     Merger."
 
     2. Section 7.1 of the Amended Registration Agreement is hereby amended and
replaced in its entirety with the following:
 
     "7.1 Termination. At any time prior to the Effective Time, whether before
or after approval of the matters presented in connection with the Merger by the
stockholders of Target, this Agreement may be terminated:
 
          (a) by mutual consent of Acquiror and Target;
 
          (b) by either Acquiror or Target if, without fault of the terminating
     party, the Closing shall not have occurred on or before September 30, 1997
     (or such later date as may be agreed upon in writing by the parties
     hereto);
 
          (c) by Acquiror, if (i) Target shall breach any of its
     representations, warranties or obligations hereunder in any material
     respects and such breach shall not have been cured within ten business days
     of receipt by Target of written notice of such breach, (ii) the Board of
     Directors of Target shall have withdrawn or modified its recommendation of
     this Agreement or the Merger in a manner adverse to Acquiror or shall have
     resolved to do any of the foregoing, or (iii) for any reason Target fails
     to call and hold the Target Stockholders' Meeting by September 30, 1997;
 
          (d) by Target, if Acquiror shall breach any of its representations,
     warranties or obligations hereunder in any material respects and such
     breach shall not have been cured within ten days following receipt by
     Acquiror of written notice of such breach;
 
          (e) by either Acquiror or Target if a Trigger Event (as defined in
     Section 7.3(b)) or Takeover Proposal shall have occurred and the Board of
     Directors of Target in connection therewith withdraws or modifies its
     approval and recommendation of this Agreement and the transactions
     contemplated hereby after determining that to cause Target to proceed with
     the transactions contemplated hereby would not be consistent with the Board
     of Directors' fiduciary duty to the stockholders of Target; or
 
          (f) by either Acquiror or Target if (i) any permanent injunction or
     other order of a court or other competent authority preventing the
     consummation of the Merger shall have become final and nonappealable or
     (ii) if any required approval of the stockholders of Target shall not have
     been obtained by reason of the failure to obtain the required vote upon a
     vote held at a duly held meeting of stockholders or at any adjournment
     thereof."
 
     3. Exhibit A of the Amended Reorganization Agreement is hereby amended such
that all references to the Amended Reorganization Agreement shall be to the
Amended Reorganization Agreement, as amended by this Amendment.
 
     4. This Amendment may be executed in two or more counterparts, each of
which shall be deemed an original, but all of which together shall constitute
one and the same instrument.
 
     5. Capitalized terms not otherwise defined herein shall have the meaning
given to them in the Amended Reorganization Agreement.

              SECTION 262 OF THE DELAWARE GENERAL CORPORATION LAW
 
  SEC. 262.  APPRAISAL RIGHTS.
 
     (a) Any stockholder of a corporation of this State who holds shares of
stock on the date of the making of a demand pursuant to subsection (d) of this
section with respect to such shares, who continuously holds such shares through
the effective date of the merger or consolidation, who has otherwise complied
with the provisions of subsection (d) of this Section and who has neither voted
in favor of the merger or consolidation nor consented thereto in writing
pursuant to sec. 228 of this Chapter shall be entitled to an appraisal by the
Court of Chancery of the fair value of his shares of stock under the
circumstances described in subsections (b) and (c) of this Section. As used in
this Section, the word "stockholder" means a holder of record of stock in a
stock corporation and also a member of record of a non-stock corporation; the
words "stock" and "share" mean and include what is ordinarily meant by those
words and also membership or membership interest of a member of a non-stock
corporation; and the words "depository receipt" mean a receipt or other
instrument issued by a depository representing an interest in one or more
shares, or fractions thereof, solely of stock of a corporation, which stock is
deposited with the depository.
 
     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to Sections 251, 252, 254, 257, 258, 263 or 264 of this
Chapter;
 
          (1) provided, however, that no appraisal rights under this Section
     shall be available for the shares of any class or series of stock, which
     stock, or depository receipts in respect thereof, at the record date fixed
     to determine the stockholders entitled to receive notice of and to vote at
     the meeting of stockholders to act upon the agreement of merger or
     consolidation, were either (i) listed on a national securities exchange or
     designated as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii) held
     of record by more than 2,000 holders; and further provided that no
     appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not require
     for its approval the vote of the stockholders of the surviving corporation
     as provided in subsection (f) of Section 251 of this Chapter.
 
          (2) Notwithstanding the provisions of subsection (b)(1) of this
     Section, appraisal rights under this section shall be available for the
     shares of any class or series of stock of a constituent corporation if the
     holders thereof are required by the terms of an agreement of merger or
     consolidation pursuant to Sections 251, 252, 254, 257, 258, 263 and 264 of
     this Chapter to accept for such stock anything except (i) shares of stock
     of the corporation surviving or resulting from such merger or
     consolidation, or depository receipts in respect thereof; (ii) shares of
     stock of any other corporation, or depository receipts in respect thereof,
     which shares of stock or depository receipts at the effective date of the
     merger or consolidation will be either listed on a national securities
     exchange or designated as a national market system security on an
     interdealer quotation system by the National Association of Securities
     Dealers, Inc. or held of record by more than 2,000 holders; (iii) cash in
     lieu of fractional shares or fractional depository receipts described in
     the foregoing clauses (i) and (ii); or (iv) any combination of the shares
     of stock, depository receipts and cash in lieu of fractional shares or
     fractional depository receipts described in the foregoing clauses (i), (ii)
     and (iii) of this subsection.
 
          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under Section 253 of this Chapter is not owned
     by the parent corporation immediately prior to the merger, appraisal rights
     shall be available for the shares of the subsidiary Delaware corporation.
 
                                      BB-1
<PAGE>   195
 
     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this
Section shall be available for the shares of any class or series of its stock as
a result of an amendment to its certificate of incorporation, any merger or
consolidation in which the corporation is a constituent corporation or the sale
of all or substantially all of the assets of the corporation. If the certificate
of incorporation contains such a provision, the procedures of this Section,
including those set forth in subsections (d) and (e), shall apply as nearly as
is practicable.
 
     (d) Appraisal rights shall be perfected as follows:
 
     (1) If a proposed merger or consolidation for which appraisal rights are
provided under this Section is to be submitted for approval at a meeting of
stockholders, the corporation, not less than 20 days prior to the meeting, shall
notify each of its stockholders who was such on the record date for such meeting
with respect to shares for which appraisal rights are available pursuant to
subsections (b) or (c) hereof that appraisal rights are available for any or all
of the shares of the constituent corporations, and shall include in such notice
a copy of this Section. Each stockholder electing to demand the appraisal of his
shares shall deliver to the corporation, before the taking of the vote on the
merger or consolidation, a written demand for appraisal of his shares. Such
demand will be sufficient if it reasonably informs the corporation of the
identity of the stockholder and that the stockholder intends thereby to demand
the appraisal of his shares. A proxy or vote against the merger or consolidation
shall not constitute such a demand. A stockholder electing to take such action
must do so by a separate written demand as herein provided. Within 10 days after
the effective date of such merger or consolidation, the surviving or resulting
corporation shall notify each stockholder of each constituent corporation who
has complied with the provisions of this subsection and has not voted in favor
of or consented to the merger or consolidation of the date that the merger or
consolidation has become effective; or
 
     (2) If the merger or consolidation was approved pursuant to Section 228 or
Section 253 of this Chapter, the surviving or resulting corporation, either
before the effective date of the merger or consolidation or within 10 days
thereafter, shall notify each of the stockholders entitled to appraisal rights
of the effective date of the merger or consolidation and that appraisal rights
are available for any or all of the shares of the constituent corporation, and
shall include in such notice a copy of this Section. The notice shall be sent by
certified or registered mail, return receipt requested, addressed to the
stockholder at his address as it appears on the records of the corporation. Any
stockholder entitled to appraisal rights may, within 20 days after the date of
mailing of the notice, demand in writing from the surviving or resulting
corporation the appraisal of his shares. Such demand will be sufficient if it
reasonably informs the corporation of the identity of the stockholder and that
the stockholder intends thereby to demand the appraisal of his shares.
 
     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with the provisions of subsections (a) and (d) hereof and who is
otherwise entitled to appraisal rights, may file a petition in the Court of
Chancery demanding a determination of the value of the stock of all such
stockholders. Notwithstanding the foregoing, at any time within 60 days after
the effective date of the merger or consolidation, any stockholder shall have
the right to withdraw his demand for appraisal and to accept the terms offered
upon the merger or consolidation. Within 120 days after the effective date of
the merger or consolidation, any stockholder who has complied with the
requirements of subsections (a) and (d) hereof, upon written request, shall be
entitled to receive from the corporation surviving the merger or resulting from
the consolidation a statement setting forth the aggregate number of shares not
voted in favor of the merger or consolidation and with respect to which demands
for appraisal have been received and the aggregate number of holders of such
shares. Such written statement shall be mailed to the stockholder within 10 days
after his written request for such a statement is received by the surviving or
resulting corporation or within 10 days after expiration of the period for
delivery of demands for appraisal under subsection (d) hereof, whichever is
later.
 
                                      BB-2
<PAGE>   196
 
     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by one or more publications at
least one week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.
 
     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with the provisions of this Section and who have
become entitled to appraisal rights. The Court may require the stockholders who
have demanded an appraisal for their shares and who hold stock represented by
certificates to submit their certificates of stock to the Register in Chancery
for notation thereon of the pendency of the appraisal proceedings; and if any
stockholder fails to comply with such direction, the Court may dismiss the
proceedings as to such stockholder.
 
     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholders entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this Section and who has submitted his
certificate of stock to the Register in Chancery, if such is required, may
participate fully in all proceedings until it is finally determined that he is
not entitled to appraisal rights under this Section.
 
     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and in the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any other state.
 
     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.
 
     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection (d)
of this Section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal
 
                                      BB-3
<PAGE>   197
 
shall be filed within the time provided in subsection (e) of this Section, or if
such stockholder shall deliver to the surviving or resulting corporation a
written withdrawal of his demand for an appraisal and an acceptance of the
merger or consolidation, either within 60 days after the effective date of the
merger or consolidation as provided in subsection (e) of this Section or
thereafter with the written approval of the corporation, then the right of such
stockholder to an appraisal shall cease. Notwithstanding the foregoing, no
appraisal proceeding in the Court of Chancery shall be dismissed as to any
stockholder without the approval of the Court, and such approval may be
conditioned upon such terms as the Court deems just.
 
     (l) The shares of the surviving or resulting corporation into which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.

Board of Directors
Cardiometrics, Inc.
645 Clyde Avenue
Mountain View, CA 94043
 
Gentlemen:
 
     We understand that Endosonics Corporation, a Delaware corporation
("Endosonics") is undertaking a transaction whereby a wholly-owned subsidiary of
Endosonics will be merged with and into Cardiometrics, Inc., a Delaware
corporation ("Cardiometrics"), pursuant to the terms of an Agreement and Plan of
Reorganization and the exhibits thereto, dated as of January 26, 1997 (the
"Merger Agreement"), such that Cardiometrics becomes a wholly-owned subsidiary
of Endosonics (the "Transaction"). Pursuant to the Transaction, each outstanding
share of Cardiometrics' Common Stock, $0.01 par value (the "Cardiometrics Common
Stock"), shall be converted into 0.35 shares of Endosonics Common Stock, $0.001
par value (the "Endosonics Common Stock"), 0.20 shares of Cardiovascular
Dynamics, Inc. ("Cardiovascular Dynamics") Common Stock, $0.001 par value (the
"Cardiovascular Dynamics Common Stock"), subject to adjustment as set forth in
the Merger Agreement, and $2.00 in cash (the "Consideration"). The terms and
conditions of the Transaction are more fully set forth in the Merger Agreement.
 
     You have requested our opinion as to whether the Consideration to be
received by the holders of Cardiometrics Common Stock (the "Holders") in the
Transaction is fair to such Holders, from a financial point of view.
 
     Dillon, Read & Co. Inc. has acted as financial advisor to the Board of
Directors of Cardiometrics in connection with the Merger and will receive a fee
upon the consummation thereof. In the ordinary course of business, we have
traded securities of Cardiometrics for our own account and for the accounts of
our customers and have traded securities of Endosonics for the accounts of our
customers and, accordingly, may at any time hold a long or short position in
such securities.
 
     In arriving at our opinion, we have, among other things: (i) reviewed
certain publicly available business and historical financial information
relating to Cardiometrics, Endosonics and Cardiovascular Dynamics, (ii) reviewed
certain management estimates and company financial forecasts prepared by the
managements of Cardiometrics and Endosonics, (iii) reviewed certain publicly
available analyst financial forecasts relating to Cardiometrics, Endosonics and
Cardiovascular Dynamics, (iv) reviewed certain financial information and other
data provided to us by Cardiometrics that is not publicly available relating to
the business and prospects of Cardiometrics, (v) reviewed certain financial
information and other data provided to us by Endosonics that is not publicly
available relating to the business and prospects of Endosonics (vi) conducted
discussions with members of the senior managements of Cardiometrics, Endosonics,
and Cardiovascular Dynamics with respect to the operations, financial condition,
history and prospects of each company including a review of publicly available

analyst financial forecasts, (vii) reviewed publicly available financial and
stock market data with respect to certain other companies in lines of business
we believe to be generally comparable to those of Cardiometrics, Endosonics and
Cardiovascular Dynamics, (viii) considered the pro forma effects of the
Transaction on Endosonics' financial statements and reviewed certain estimates
of synergies prepared by the management of Cardiometrics, (ix) reviewed the
historical market prices and trading volumes of the Cardiometrics Common Stock,
the Endosonics Common Stock and the Cardiovascular Dynamics Common Stock, (x)
compared the financial terms of the Transaction with the financial terms of
certain other transactions which we believe to be generally comparable to the
Transaction, (xi) reviewed the Merger Agreement, and (xii) conducted such other
financial studies, analyses, and investigations, and considered such other
information as we deemed necessary or appropriate.
 
     In connection with our review, we have not independently verified any of
the foregoing information and have, with your consent, relied on its being
complete and accurate in all material respects. In addition, we have not made
any evaluation or appraisal of any of the assets or liabilities (contingent or
otherwise) of Cardiometrics, Endosonics and Cardiovascular Dynamics. With
respect to the financial forecasts referred to above, we have assumed, with your
consent, that the Cardiometrics and Endosonics company financial forecasts and
the most recent publicly available Cardiovascular Dynamics analyst financial
forecast have been prepared reasonably on a basis reflecting the best currently
available estimates and judgments of the respective managements as to the future
financial performance of their respective companies. We understand that
Cardiometrics, from time to time, has conducted discussions relating to a
potential transaction with parties other than Endosonics, however, we were not
authorized, and did not, solicit other third party offers for either all or a
portion of Cardiometrics. Further, our opinion is based on economic, monetary,
and market conditions existing on the date hereof.
 
     Based upon and subject to the foregoing, it is our opinion that, as of the
date hereof, the Consideration to be received by the Holders in the Transaction
is fair to such Holders from a financial point of view.
 
                                          Very truly yours,

                                VOTING AGREEMENT
 
     This Voting Agreement (the "Agreement") is made and entered into as of
January 26, 1997, between EndoSonics Corporation, a Delaware corporation
("Acquiror"), and the undersigned stockholder ("Stockholder") of Cardiometrics,

(the "Merger") and Target, as the surviving corporation of the Merger, will

Target to execute and deliver to Acquiror Voting Agreements;
 
     C. The Stockholder is the beneficial owner (as defined in Rule 13d-3 under
the Securities Exchange Act of 1934, as amended (the "Exchange Act")) of such

Target as is indicated on the final page of this Agreement (the "Shares"); and
 
     D. In consideration of the execution of the Reorganization Agreement by
Acquiror, Stockholder agrees not to transfer or otherwise dispose of any of the
Shares, or any other shares of capital stock of Target acquired by Stockholder

     exchange, pledge or otherwise dispose of or encumber the Shares or any New
     Shares (as defined in Section 1.2) prior to the Expiration Date and to be
     subject to the Proxy (as defined in Section 3)) or otherwise dispose of or
     encumber the Shares or any New Shares, or to make any offer or agreement
     relating thereto, at any time prior to the Expiration Date. As used herein,
     the term "Expiration Date" shall mean the earlier to occur of (i) such date
     and time as the Merger shall become effective in accordance with the terms
     and provisions of the Reorganization Agreement and (ii) six months after
     the date of termination of the Reorganization Agreement.
 
          1.2  New Shares.  Stockholder agrees that any shares of capital stock
     of Target that Stockholder purchases or with respect to which Stockholder
     otherwise acquires beneficial ownership after the date of this Agreement
     and prior to the Expiration Date ("New Shares") shall be subject to the
     terms and conditions of this Agreement to the same extent as if they
     constituted Shares.
 
     2. Agreement to Vote Shares.  At every meeting of the stockholders of
Target called with respect to any of the following, and at every adjournment
thereof, and on every action or approval by written consent of the stockholders
of Target with respect to any of the following, Stockholder shall vote the

for any recapitalization, merger, sale of assets or other business combination
(other than the Merger) between Target and any person or entity other than
Acquiror or any other action or agreement that would result in a breach of any
covenant, representation or warranty or any other obligation or agreement of
Target under the Reorganization Agreement or which would result in any of the
conditions to Target's obligations under the Reorganization Agreement not being
fulfilled.
 
     3. Irrevocable Proxy.  Concurrently with the execution of this Agreement,
Stockholder agrees to deliver to Acquiror a proxy in the form attached hereto as
Exhibit A (the "Proxy"), which shall be irrevocable to the extent provided in
Section 212 of the Delaware General Corporation Law, covering the total number
of Shares and New Shares beneficially owned or as to which beneficial ownership
is acquired (as such term is defined in Rule 13d-3 under the Exchange Act) by
Stockholder set forth therein.
 
     4. Representations, Warranties and Covenants of Stockholder.  Stockholder
hereby represents, warrants and covenants to Acquiror that Stockholder (i) is

and intent of this Agreement.

herewith shall terminate and shall have no further force or effect as of the
Expiration Date.
 
     8. Miscellaneous.
 
          8.1  Severability.  If any term, provision, covenant or restriction of
     this Agreement is held by a court of competent jurisdiction to be invalid,
     void or unenforceable, then the remainder of the terms, provisions,
     covenants and restrictions of this Agreement shall remain in full force and
     effect and shall in no way be affected, impaired or invalidated.
 
          8.2  Binding Effect and Assignment.  This Agreement and all of the

     acknowledge that Acquiror will be irreparably harmed and that there will be

     in addition to any other remedies that may be available to Acquiror upon
     any such violation, Acquiror shall have the right to enforce such covenants
     and agreements by specific performance, injunctive relief or by any other
     means available to Acquiror at law or in equity.

     THIS AMENDMENT NO. 1 to the Voting Agreement (the "Original Voting

     of such number of shares of the outstanding Common Stock, $0.01 par value
     per share, of Target as is indicated on the final page of this Agreement
     (the "Total Shares," of which shares the number of issued and outstanding

          "1.2  New Shares. Stockholder agrees that any shares of capital stock

     an exercise price less than $8.00 ("New Shares") shall be subject to the
     terms and conditions of this Agreement to the same extent as if they
     constituted Shares."

     1.1  Non-Competition.
 
     (a) The parties understand and agree that this Agreement is entered into in
connection with the Merger. The parties further understand and agree that
Employee is a key and significant member of the Company and owns a significant
equity interest in the Company. In addition, the parties understand that prior
to the Merger, the Company was engaged in the Business (as defined below) in
each of the fifty states of the United States (together with its territories and
possessions and the District of Columbia) and Canada. (The United States and

following the Merger will continue conducting such business in all parts of the
Geographic Scope of the Business. The parties expressly acknowledge and agree
that the non-competition provisions contained in this Agreement are permissible
and enforceable pursuant to the provisions of applicable law.
 
          (b) During the period commencing on the Closing Date (as defined in
     the Merger Agreement) of the Merger and ending the earlier of six months
     after Employee's cessation of employment with EndoSonics and 12 months
     after the Closing Date (the "Restricted Period"), without the prior written
     consent of the Chief Executive Officer of EndoSonics, Employee shall not

     general partner, officer, director, shareholder or investor of any person,
     firm, corporation, partnership or other entity:
 
             (i) participate or engage in the design, development, manufacture,
        production, marketing, sale or servicing of any product, or the
        provision of any service, that directly relates to the functional
        testing in the cardiac catheter laboratory utilizing flow and/or
        pressure sensor based angioplasty guide wires and corresponding
        instrumentation (the "Business") in the United States or Canada;
 
             (ii) induce or attempt to induce any person who at the time of such
        inducement is an employee of Subsidiary or EndoSonics to perform work or
        services for any other person or entity other than Subsidiary or

     Notwithstanding the foregoing, Employee may own, directly or indirectly,
solely as an investment, up to 1% of any class of "publicly traded securities"
of any person or entity which owns a competitive Business, and up to 5% of the
outstanding securities that are not "publicly traded securities" of any person
or entity which owns a competitive Business. For the purposes of this Section
1.1, the term "publicly traded securities" shall mean securities that are traded
on a national securities exchange or listed on the National Association of
Securities Dealers Automated Quotation System.
 
     Notwithstanding the foregoing, Employee will not be prohibited from

of property belonging to, Acquiror; or (v) material breach of this agreement or
any confidentiality or proprietary information agreement between you and
Acquiror; provided, however, that if such "Cause is reasonably curable, Acquiror
shall not terminate your employment hereunder unless it first gives you notice
of its intention to terminate and the grounds of such termination and you have
not, within 30 days following the receipt of such notice, cured such "Cause."
Acquiror will provide written notice of the reason for termination in the case
of any termination for "Cause." A termination for any other reason shall be a
termination "Without Cause."
 
     1.2  Arbitration; Consent to Personal Jurisdiction.
 
     (a) Employee agrees that any dispute or controversy arising out of,
relating to, or in connection with this Agreement, or the interpretation,

accordance with the Commercial Arbitration Rules of the American Arbitration
Association, supplemented by the Large Complex Case Procedures of the American
Arbitration Association (the "Rules"). The arbitrator may grant injunctions or
other relief in such dispute or controversy. The decision of the arbitrator
shall be final, conclusive and binding on the parties to the arbitration.
Judgment may be entered on the arbitrator's decision in any court having
jurisdiction.
 
     (b) At the request of either party, the arbitration proceedings pursuant

     (c) The arbitrator(s) shall apply California law to the merits of any
dispute or claim, without reference to rules of conflicts of law. The

ARBITRATION. EMPLOYEE UNDERSTANDS THAT BY SIGNING THIS AGREEMENT, EMPLOYEE
AGREES TO SUBMIT ANY CLAIMS ARISING OUT OF, RELATING TO, OR IN CONNECTION WITH
THIS AGREEMENT, OR THE INTERPRETATION, VALIDITY, CONSTRUCTION, PERFORMANCE,
BREACH OR TERMINATION THEREOF TO BINDING ARBITRATION, AND THAT THIS ARBITRATION
CLAUSE CONSTITUTES A WAIVER OF EMPLOYEE'S RIGHT TO A JURY TRIAL AND RELATES TO
THE RESOLUTION OF ALL DISPUTES RELATING TO THIS AGREEMENT.
 
     1.3  Savings Clause.  If any restriction set forth in Section 1.1 above is
held to be unreasonable or unenforceable, then Employee agrees, and hereby

regard to conflicts of laws and principles. Each provision of this Agreement is
severable from the others, and if any provision hereof shall be to any extent

                             STOCK OPTION AGREEMENT
 
     STOCK OPTION AGREEMENT (the "Agreement"), dated as of January 26, 1997, by
and between EndoSonics Corporation, a Delaware corporation ("Acquiror"), and
Cardiometrics, Inc., a Delaware corporation ("Target").
 
     WHEREAS, concurrently with the execution and delivery of this Agreement,
Target, Acquiror and River Acquisition Corporation, a Delaware corporation
("Sub"), are entering into an Agreement and Plan of Reorganization, dated as of
the date hereof (the "Reorganization Agreement"), which provides that, among
other things, upon the terms and subject to the conditions thereof, Merger Sub
will be merged with and into Target (the "Merger"), with Target continuing as
the surviving corporation; and
 
     WHEREAS, as a condition and inducement to Acquiror's willingness to enter
into the Reorganization Agreement, Acquiror has required that Target agree, and
Target has so agreed, to grant to Acquiror an option with respect to certain
shares of Target's common stock on the terms and subject to the conditions set
forth herein.
 
     NOW, THEREFORE, in consideration of the foregoing and of the mutual
covenants and agreements set forth herein and in the Reorganization Agreement,
the parties hereto agree as follows:
 
     1. Grant of Option.  Target hereby grants Acquiror an irrevocable option
(the "Target Option") to purchase up to 1,379,717 shares (the "Target Shares")
of common stock, par value $0.01 per share, of Target (the "Target Common
Stock") in the manner set forth below at a price (the "Exercise Price") of $9.00
per Target Share, payable in cash, or at Acquiror's option, Target shall loan
Acquiror the Exercise Price (less the par value of the shares issued upon
exercise, such par value to be paid in cash), pursuant to an interest free
one-year term loan (the "Note"). Capitalized terms used herein but not defined
herein shall have the meanings set forth in the Reorganization Agreement.
 
     2. Exercise of Option.  The Target Option may be exercised by Acquiror, in
whole or in part at any time or from time to time after the occurrence of any of
the events described in Section 7.3(b) of the Reorganization Agreement or if a
Takeover Proposal or Trigger Event is consummated. In the event Acquiror wishes
to exercise the Target Option, Acquiror shall deliver to Target a written notice
(an "Exercise Notice") specifying the total number of Target Shares it wishes to
purchase. The closing of the purchase of Target Shares (the "Closing") shall
occur at a place, on a date and at a time designated by Acquiror in an Exercise
Notice delivered at least two business days prior to the date of the Closing.
The Target Option shall terminate upon the earlier of: (i) the Effective Time;
(ii) the termination of the Reorganization Agreement pursuant to Section 7.1
thereof (other than a termination in connection with which Acquiror is entitled
to any payments as specified in Sections 7.3(b)thereof); or (iii) 180 days
following any termination of the Reorganization Agreement in connection with
which Acquiror is entitled to a payment as specified in Section 7.3(b)thereof
(or if, at the expiration of such 180-day period, the Target Option cannot be
exercised by reason of any applicable judgment, decree, order, law or
regulation, ten business days after such impediment to exercise shall have been
removed or shall have become final and not subject to appeal), but in no event
under this clause (iii) later than March 31, 1998. Notwithstanding the
foregoing, (i) the Target Option may not be exercised if Acquiror is in material
breach of any of its representations, warranties, covenants or agreements
contained in this Agreement or in the Reorganization Agreement; and (ii) in the
event Acquiror receives more than the Exercise Price multiplied by the number of
Target Shares purchased by Acquiror pursuant to the Target Option, in connection
with sales or other dispositions of the Target Shares, all proceeds in excess of
such amount shall be remitted to Target.
 
     3. Conditions to Closing.  The obligation of Target to issue the Target
Shares to Acquiror hereunder is subject to the conditions that (i) all waiting
periods, if any, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
as amended, and the rules and regulations promulgated thereunder ("HSR Act"),
applicable to the issuance of the Target Shares hereunder shall have expired or
have been terminated; (ii) all consents, approvals, orders or authorizations of,
or registrations,
 
                                      FF-1

or commission or other Federal state or local governmental authority or
instrumentality, if any, required in connection with the issuance of the Target
Shares hereunder shall have been obtained or made, as the case may be; and (iii)
no preliminary or permanent injunction or other order by any court of competent
jurisdiction prohibiting or otherwise restraining such issuance shall be in
effect.
 
     4. Closing.  At the Closing, (a) Target will deliver to Acquiror a single
certificate in definitive form representing the number of Target Shares
designated by Acquiror in its Exercise Notice, such certificate to be registered
in the name of Acquiror and to bear the legend set forth in Section 13, and (b)

        event shall the proceeds payable to Acquiror pursuant to Section
        7(a)(ii) above exceed the Exercise Price multiplied by the number of

        Proposal during the Repurchase Period.

     Target the Target Option or the certificates evidencing the Target Shares

     owns such shares and that such shares are then free and clear of all liens,
     claims, charges and encumbrances of any kind or nature whatsoever.
 
          (c) Limitation on Call.  The Call shall not be exercisable by Target
     (or any successor entity thereof) unless substantially concurrently

     Takeover Proposal.

Date (as defined in Section 9 (b)hereof), Acquiror shall vote any shares of

     9. Restrictions on Certain Actions.
 
          (a) Restrictions.  Other than pursuant to the Reorganization

     Acquiror permit its affiliates to, directly or indirectly, alone or in
     concert or conjunction with any other Person or Group (as defined in
     Section 9(b)), (i) in any manner acquire, agree to acquire or make any

     property of, Target (other than pursuant to this Agreement or the

     Target, propose to enter into any merger or business combination involving
     Target or to purchase a material portion of the assets of Target, (iii)
     make or in any way participate in any "solicitation" of "proxies" (as such
     terms are used in Regulation 14A promulgated under the Exchange Act) to
     vote, or seek to advise or influence any Person with respect to the voting
     of, any voting securities of Target, (iv) form, join or in any way
     participate in a Group with respect to any voting securities of Target, (v)

     Section 9, or take any action which may require Target to make a public
     announcement regarding the possibility of a business combination or merger
     with such party. Target shall not adopt any Rights Agreement in any manner
     which would cause Acquiror, if Acquiror has complied with its obligations
     under this Agreement, to become an "Acquiring Person" under such Rights
     Agreement solely by reason of the beneficial ownership of the shares
     purchasable hereunder.
 
          (b) Certain Definitions.  For purposes of this Agreement, (i) the term
     "Person" shall mean any corporation, partnership, individual, trust,
     unincorporated association or other entity or Group (within the meaning of
     Section 13(d)(3) of the Exchange Act), (ii) the term "Expiration Date" with
     respect to any obligation or restriction imposed on one party shall mean
     the earlier to occur of (A) the third anniversary of the date hereof or (B)
     such time as the other party shall have suffered a Change of Control and
     (iii) a "Change of Control" with respect to one party shall be deemed to
     have occurred whenever (A) there shall be consummated (1) any consolidation
     or merger of such party in which such party is not the continuing or
     surviving corporation, or pursuant to which shares of such party's common
     stock would be converted in whole or in part into cash, other securities or
     other property, other than a merger of such person in which the holders of
     such party's common stock immediately prior to the merger have
     substantially the same proportionate ownership of common stock of the
     surviving corporation immediately after the merger, or (2) any

<PAGE>   215
 
     sale, lease, exchange or transfer (in one transaction or a series of
     related transactions) of all or substantially all the assets of such party,
     or (B) the stockholders of such party shall approve any plan or proposal
     for the liquidation or dissolution of such party, or (C) any party, other
     than such party or a subsidiary thereof or any employee benefit plan
     sponsored by such party or a subsidiary thereof or a corporation owned,
     directly or indirectly, by the stockholders of such party in substantially
     the same proportions as their ownership of stock of such party, shall
     become the beneficial owner of securities of such party representing 20% or
     more, or commences a tender or exchange offer following the successful
     consummation of which the offeror and its affiliates would beneficially own
     securities representing 20% or more, of the combined voting power of then
     outstanding securities ordinarily (and apart from rights accruing in
     special circumstances) having the right to vote in the election of
     directors, as a result of a tender or exchange offer, open market
     purchases, privately negotiated purchases or otherwise; provided, however,
     that a Change in Control shall not be deemed to include the acquisition by
     any party of securities representing 20% or more of Target if such party
     has acquired such securities not with the purpose nor with the effect of
     changing or influencing the control of Target, nor in connection with or as
     a participant in any transaction having such purpose or effect, including
     without limitation not in connection with such party (i) making any public
     announcement with respect to the voting of such shares at any meeting to
     consider any merger, consolidation, sale of substantial assets or other
     business combination or extraordinary transaction involving Target, (ii)
     making, or in any way participating in, any "solicitation" of "proxies" (as
     such terms are defined or used in Regulation 14A under the Exchange Act) to
     vote any voting securities of Target (including, without limitation, any
     such solicitation subject to Rule 14a-11 under the Exchange Act) or seeking
     to advise or influence any party with respect to the voting of any voting
     securities of Target, directly or indirectly, relating to a merger or other
     business combination involving Target or the sale or transfer of any

     ordinary course of business) of Target, (iii) forming, joining or in any
     way participating in any "group" within the meaning of Section 13(d)(3) of
     the Exchange Act with respect to any voting securities of Target, directly
     or indirectly, relating to a merger or other business combination involving
     Target or the sale or transfer of any material assets (excluding the sale
     or disposition of assets in the ordinary course of business) of Target, or
     (iv) otherwise acting, alone or in concert with others, to seek control of
     Target or to seek to control or influence the management or policies of
     Target, or (D) at any time during the period commencing on the date of this
     Agreement and ending on the Expiration Date, individuals who at the date
     hereof constituted the Board of Directors of such party shall cease for any
     reason to constitute at least a majority thereof, unless the election or
     the nomination for election by such party's stockholders of each new
     director during the period commencing on the date of this Agreement and
     ending on the Expiration Date was approved by a vote of at least two-thirds
     of the directors then still in office who were directors at the date
     hereof, or (E) any other event shall occur with respect to such party that
     would be required to be reported in response to Item 6(e) (or any successor
     provision) of Schedule 14A of Regulation 14A promulgated under the Exchange
     Act.
 
     10. Restrictions on Transfer.
 
          (a) Restrictions on Transfer.  Prior to the Expiration Date, Acquiror

     beneficially owned by Acquiror, other than (i) pursuant to Section 7, or
     (ii) in accordance with Section 10(b).
 
          (b) Permitted Sales.  Following the termination of the Reorganization
     Agreement, Acquiror shall be permitted to sell any Restricted Shares
     beneficially owned by it if such sale is made pursuant to a tender or
     exchange offer that has been approved or recommended, or otherwise
     determined to be fair and in the best interests of the stockholders of
     Target, by a majority of the members of the Board of Directors of Target
     (which majority shall include a majority of directors who were directors
     prior to the announcement of such tender or exchange offer).

     11. Adjustment Upon Changes in Capitalization.  In the event of any change
in Target Common Stock by reason of stock dividends, splitups, mergers (other
than the Merger), recapitalizations, combinations, exchange of shares or the
like, the type and number of shares or securities subject to the Target Option,
and the purchase price per share provided in Section 1, shall be adjusted
appropriately, and proper provision shall be made in the agreements governing
such transaction so that Acquiror shall receive, upon exercise of the Target
Option, the number and class of shares or other securities or property that
Acquiror would have received in respect of the Target Common Stock if the Target
Option had been exercised immediately prior to such event or the record date
therefor, as applicable.
 
     12. Restrictive Legends.  Each certificate representing shares of Target
Common Stock issued to Acquiror hereunder shall include a legend in
substantially the following form:
 
     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY BE REOFFERED OR SOLD ONLY
IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE. SUCH

BE OBTAINED FROM THE ISSUER.
 
     13. Binding Effect; No Assignment.  This Agreement shall be binding upon
and inure to the benefit of the parties hereto and their respective successors
and permitted assigns. Except as expressly provided for in this Agreement,
neither this agreement nor the rights or the obligations of either party hereto
are assignable or transferable, except by operation of law or with the written
consent of the other party. Nothing contained in this Agreement, express or
implied, is intended to confer upon any person other than the parties hereto and
their respective permitted assigns any rights or remedies of any nature
whatsoever by reason of this Agreement.
 
     14. Specific Performance.  The parties recognize and agree that if for any
reason any of the provisions of this Agreement are not performed in accordance
with their specific terms or are otherwise breached, immediate and irreparable
harm or injury would be caused for which money damages would not be an adequate
remedy. Accordingly, each party agrees that, in addition to other remedies, the
other party shall be entitled to an injunction restraining any violation or
threatened violation of the provisions of this Agreement. In the event that any
action should be brought in equity to enforce the provisions of this Agreement,
neither party will allege, and each party hereby waives the defense, that there
is adequate remedy at law.
 
     15. Entire Agreement.  This Agreement and the Reorganization Agreement
(including the Target Disclosure Schedule and the Acquiror Disclosure Schedule
relating thereto) constitute the entire agreement among the parties with respect
to the subject matter hereof and supersede all other prior agreements and
understandings, both written and oral, among the parties or any of them with
respect to the subject matter hereof.
 
     16. Further Assurance.  Each party will execute and deliver all such
further documents and instruments and take all such further action as may be
necessary in order to consummate the transactions contemplated hereby.
 
     17. Validity.  The invalidity or unenforceability of any provision of this
Agreement shall not affect the validity or enforceability of the other
provisions of this Agreement, which shall remain in full force and effect. In
the event any court or other competent authority holds any provision of this
Agreement to be null, void or unenforceable, the parties hereto shall negotiate
in good faith the execution and delivery of an amendment to this Agreement in
order, as nearly as possible, to effectuate, to the extent permitted by law, the
intent of the parties hereto with respect to such provision. Each party agrees
that, should any court or other competent authority hold any provision of this
Agreement or part hereof to be null, void or unenforceable, or order any party
to take any action inconsistent herewith, or not take any action required
herein, the other party shall not be entitled to specific performance of such
provision or

part hereof or to any other remedy, including but not limited to money damages,
for breach hereof or of any other provision of this Agreement or part hereof as
the result of such holding or order.

     This Prospectus relates to the public offering, which is not being
underwritten, of 1,488,528 shares of Common Stock, $.001 par value per share
(the "Shares"), of CardioVascular Dynamics, Inc. ("CVD," the "Company" or the

EndoSonics of all of the outstanding capital stock of the Company pursuant to an
Agreement and Plan of Reorganization between EndoSonics and the Company dated
June 9, 1993, and in connection with the acquisition by EndoSonics of 400,000
shares of the Company's Series B Preferred Stock on March 29, 1996, which
converted into 800,000 shares of Common Stock upon the consummation of the
Company's initial public offering. The Shares are being registered by the
Company pursuant to a registration rights agreement by and between the Company
and EndoSonics entered into in connection with the acquisition of Cardiometrics,
Inc. ("Cardiometrics") by EndoSonics pursuant to an Agreement and Plan of
Reorganization, dated as of January 26, 1997, as subsequently amended, among
EndoSonics, River Acquisition Corporation, a wholly-owned subsidiary of
EndoSonics, and Cardiometrics. All 1,488,528 of the Shares may be distributed by
Endosonics directly to the former stockholders, warrantholders and optionholders
of Cardiometrics in connection with the acquisition. The Shares were issued
pursuant to an exemption from the registration requirements of the Securities
Act of 1933, as amended (the "Securities Act"), provided by Section 4(2)
thereof. See "Prospectus Summary -- The Merger."
 
     After the distribution hereunder, EndoSonics is expected to own
approximately 28% of the Company's outstanding Common Stock.
 
     The Company will not receive any of the proceeds from the transfer or sale
of the Shares. The Company shall not bear any expenses in connection with the
registration of the Shares being distributed by EndoSonics; such expenses shall
be paid by EndoSonics.
 
     As of the date of this Prospectus, stockholders holding approximately
4,686,000 shares have certain registration rights with respect to such shares.

                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information and financial statements and notes thereto appearing elsewhere in
this Prospectus. This Prospectus contains forward-looking statements that
involve risks and uncertainties. The Company's actual results may differ
materially from those described in the forward-looking statements. Investors
should carefully consider the information under the heading "Risk Factors" in
addition to the other information contained in this Prospectus before purchasing
the Common Stock offered hereby.
 
                                  THE COMPANY
 
     CardioVascular Dynamics, Inc. ("CVD" or the "Company") designs, develops,
manufactures and markets catheters used to treat certain vascular diseases. The
Company's catheters are used in conjunction with angioplasty and other
interventional procedures such as vascular stenting and drug delivery. The
Company's proprietary Focus and Multiple Microporous Membrane ("M(3)")
technologies enable physicians to deliver therapeutic radial force, stents,
drugs or contrast media accurately and effectively to the treatment site, and
also allow the perfusion of blood during an interventional procedure. The
Company believes that the combination of these technologies on a
multiple-purpose catheter enables physicians to effectively perform challenging
interventional procedures, resulting in improved treatment outcomes and lower
costs. The Company has eleven issued U.S. patents covering certain aspects of
its catheter technologies.
 
     Cardiovascular disease, the leading cause of death in the United States, is
caused principally by atherosclerosis. Atherosclerosis is a progressive and
degenerative vascular disease in which cholesterol and other fatty materials are
deposited on the walls of blood vessels, forming a build-up known as plaque.
Treatments for atherosclerosis include drug therapy and open-heart bypass
surgery. In addition, cardiologists are increasingly utilizing minimally
invasive catheter-based treatments such as balloon angioplasty, atherectomy and
laser angioplasty to treat atherosclerosis.
 
     Although catheter-based interventional therapies are generally successful
in initially increasing blood flow, studies indicate that after a traditional
coronary balloon angioplasty up to 50% of treated patients experience restenosis
(generally defined as a 50% or greater reduction in the lumen, or interior,
diameter of the treated vessel at the lesion site). In addition, studies show
that 5% to 8% of elective coronary balloon angioplasty patients may experience
acute reclosure of the treated vessel. Acute reclosure is an increase in the
severity of the vessel closure accompanied by a reduction in blood flow within
the vessel as a consequence of the intervention which occurs within 24 hours of
the procedure. A study has also indicated that angioplasty of chronic total
occlusions represents 10% to 20% of all coronary angioplasty procedures. A
chronic total occlusion is a complete blockage of the vessel preventing blood
flow beyond the lesion site. The Company believes that these challenges are
inadequately addressed with existing, single function, uniform diameter
angioplasty balloons. However, while the Company believes that its products
address certain disadvantages of existing catheter technology, limitations
remain in the use of balloon angioplasty to treat atherosclerosis. The Company's
products may not be suitable for the treatment of all forms of atherosclerosis.
For example, in many cases the existence of a total occlusion limits treatment
options to bypass surgery.
 
     CVD has utilized its core proprietary technologies to develop catheters
that provide clinical and cost benefits in the treatment of vascular diseases.
The Company's catheters are designed to address three principal challenges
facing cardiologists: restenosis of a treated vessel, chronic total occlusions
and acute reclosure of a vessel during or soon after a procedure. The Company's
patented Focus technology combines compliant and non-compliant balloon materials
on a single catheter, creating an angioplasty balloon that has an adjustable,
larger center diameter with fixed, smaller diameters at each end. These
characteristics allow a single balloon to expand to multiple diameters, enabling
the physician to perform interventional procedures in vessels of varying
diameters and anatomical locations. The Company's proprietary M(3) technology
combines multiple membranes of polymeric balloon material to form a single
balloon that enables the accurate delivery of drugs or contrast agents to the
lesion or thrombus site. The M(3) technology can also be utilized to provide
perfusion of blood during an interventional procedure. The Company believes that
the Focus and M(3) technologies may enable physicians to cost-effectively treat
vascular diseases by reducing the cost of those procedures which require more
than one catheter.

                                   THE MERGER
 
     On January 26, 1997, EndoSonics and Cardiometrics entered into an agreement
which would result in the acquisition of Cardiometrics by EndoSonics through the
merger (the "Merger") of River Acquisition Corporation ("Merger Sub"), a
wholly-owned subsidiary of EndoSonics, with and into Cardiometrics.
 
     The Merger is subject to the terms and conditions of an Agreement and Plan
of Reorganization, dated as of January 26, 1997, as subsequently amended (the
"Reorganization Agreement"), among Endosonics, Merger Sub and Cardiometrics. In
the Merger, Merger Sub will be merged with and into Cardiometrics; Cardiometrics
will be the surviving corporation and will become a wholly-owned subsidiary of
EndoSonics. Pursuant to the Merger, each outstanding share of the 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 the
following (the "Merger Consideration"): (i) .35 shares of EndoSonics Common
Stock; (ii) $3.00 in cash; and (iii) at least .1364 but no more than .19 shares
of CVD Common Stock (adjusted as set forth in the following sentence, the "CVD
Exchange Ratio"). If, based on the average closing prices of EndoSonics Common
Stock and CVD Common Stock for the ten trading days immediately preceding (and
including) the third trading day prior to the special meeting of Cardiometrics'
stockholders to approve the Merger and using a CVD Exchange Ratio of .1364, the
Merger Consideration would be less than $8.00, the CVD Exchange Ratio will be
increased from .1364 such that the Merger Consideration shall equal $8.00, but
in no event shall the CVD Exchange Ratio exceed .19. 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 and each outstanding warrant to purchase shares of
Cardiometrics Common Stock (a "Cardiometrics Warrant") will be assumed in part
by EndoSonics and converted into an option or warrant, as applicable, to
purchase 0.35 shares of EndoSonics Common Stock for each share of Cardiometrics
Common Stock subject to that option or warrant, as applicable, immediately prior
to the Merger, and the exercise price per share payable under the assumed option
or warrant, as applicable, will be appropriately adjusted to reflect such
conversion ratio. The balance of each Cardiometrics Option and Cardiometrics
Warrant 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 or warrant, as
applicable, immediately prior to the Merger, less (ii) the difference between
the aggregate exercise price in effect for that option or warrant, as
applicable, immediately prior to the Merger and the aggregate exercise price in
effect for that option or warrant, as applicable, 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.
 
                                  RISK FACTORS
 
     An investment in the Common Stock offered hereby is subject to numerous
risks. The Company has a history of operating losses, expects to continue to
incur operating losses and may require additional funding. The Company is
dependent upon the development, manufacture and introduction of new products in
an industry characterized by rapid technological change, and its products are
subject to the risk of obsolescence. CVD has limited sales to date and there can
be no assurance that the Company's products will achieve market acceptance. In
addition, CVD has experienced and expects to continue to experience significant
fluctuations in quarterly operating results. CVD's stock price has been volatile
and the distribution of CVD Common Stock by EndoSonics in connection with the
Merger could adversely affect the market price of the CVD Common Stock. There
can be no assurance that the Company's intellectual property will provide
competitive advantages or that the Company's products do not infringe the
intellectual property rights of others. The Company's products compete with or
will compete with products marketed by a number of other manufacturers, many of
whom have established market positions and significantly greater resources than
the Company. The Company has very limited experience manufacturing its products
and may experience difficulties in manufacturing scale-up. CVD has experienced a
period of significant expansion of its operations, and there can be no assurance
that it will be able to manage current and future growth. Products offered by
the

Company are subject to approval by regulatory authorities and failure to obtain
or maintain such approvals may delay or prevent the introduction or marketing of
the Company's products. The Company also has limited marketing and sales
resources and depends upon the marketing capabilities of certain strategic
partners for the distribution of its products. Other factors to be considered
include: dependence upon international sales; limitations on third-party
reimbursement; control by existing stockholder and limitations on pooling-of-
interests accounting in merger transactions; dependence upon key personnel;
potential product liability and limited insurance; shares eligible for future
sale and potential adverse effect on market price; effect of certain charter
provisions and anti-takeover effects of Certificate of Incorporation, Bylaws and
Delaware Law; and absence of dividends. Cardiometrics stockholders should
carefully consider the information set forth under the heading "Risk Factors" in
addition to the other information contained in this Prospectus before acquiring
the Common Stock offered hereby.

                                  RISK FACTORS
 
     In evaluating the Company's business, prospective investors should consider
carefully the following risk factors in addition to the other information
presented in this Prospectus. This Prospectus contains forward looking
statements that involve risks and uncertainties. The Company's actual results
may differ materially from those described in the forward-looking statements.
Investors should carefully consider the following risk factors in addition to
the other information contained in this Prospectus before purchasing the Common
Stock offered hereby.
 
     History of Operating Losses; Anticipated Future Losses; Future Capital
Requirements.  The Company was founded in 1992 and has experienced annual
operating losses since its inception. Its net loss was $1.0 million, $2.9
million and $4.6 million in 1994, 1995 and 1996, respectively. The Company's
accumulated deficit at March 31, 1997 was approximately $11.6 million. The
Company expects to continue to incur operating losses through at least 1997 and
there can be no assurance that the Company will ever be able to achieve or
sustain profitability in the future. The Company expects to incur substantially
increased costs related to, among other things, clinical testing, product
development, manufacturing scale-up and sales and marketing activities. The
Company anticipates that its existing capital resources will be sufficient to
fund its operations through 1997. The Company's future capital requirements will
depend on many factors, including its research and development programs, the
scope and results of clinical trials, the time and costs involved in obtaining
regulatory approvals, the costs involved in obtaining and enforcing patents or
any litigation by third parties regarding intellectual property, the status of
competitive products, the establishment and scale-up of manufacturing capacity,
the establishment of sales and marketing capabilities, the establishment of
collaborative relationships with other parties and costs related to the
acquisition of new technologies and product development. The Company may require
additional funds to finance these activities and for working capital
requirements. The Company may seek such funds through financings, including
private or public equity or debt offerings and collaborative arrangements with
corporate partners. There can be no assurance that funds will be raised on
favorable terms, if at all. If adequate funds are not available, the Company may
be required to delay, scale back or eliminate one or more of its development
programs or obtain funds through arrangements with collaborative partners or
others that may require the Company to relinquish rights to certain
technologies, product candidates or products that the Company would not
otherwise relinquish. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
     Dependence Upon New Products; Rapid Technological Change; Risk of
Obsolescence.  The medical device industry generally, and the interventional
catheter market in particular, are characterized by rapid technological change,
changing customer needs, and frequent new product introductions. As a result,
the useful lives of both the technology and products for the treatment of
cardiovascular and peripheral vascular diseases are limited, in some instances
to as little as twelve months. The Company's future success will depend upon its
ability to develop, manufacture and introduce new products that address the
needs of its customers. There can be no assurance that the Company will be
successful in developing and marketing new products that achieve market
acceptance or that the Company will not experience difficulties that could delay
or prevent the successful development, introduction and marketing of new
products. In addition, there can be no assurance that the Company's existing
products will not be rendered obsolete as a result of technological developments
or that the products that the Company has under development will not be rendered
obsolete prior to the introduction of such products. See "Business -- Products."
 
     Limited Sales to Date; Uncertainty of Market Acceptance.  The Company's
catheters are used in conjunction with angioplasty and other intravascular
procedures such as vascular stenting and drug delivery. Although the Company has
received regulatory clearance for a total of fifty-two products, only
twenty-nine of such products have been marketed. Of those products which have
been marketed, many have been marketed only in limited quantities or in certain
markets, or are allowed to be marketed only in certain countries. In addition,
while interventional catheters are widely used technologies, the Company's
catheter designs are relatively new. The commercial success of the Company's
products will depend upon their acceptance by the medical community as useful,
cost-effective components of interventional cardiovascular and peripheral
vascular procedures, including the acceptance by the medical community of stents
and the availability and acceptance of therapeutic drugs for use in
interventional procedures. The Company currently relies upon
 
                                        7

                                     GG-7
<PAGE>   227
 
relationships with certain prominent doctors and researchers in the medical
community to promote the uses and acceptance of its approved products. There can
be no assurance that the Company will be able to maintain such relationships or
establish additional relationships in the future. The erosion or loss of any
such relationship could detrimentally affect the market acceptance of the
Company's products. Failure of the Company's products to achieve such market
acceptance would have a material adverse effect on the Company's business,
financial condition and results of operations. See "Business -- Products."
 
     Fluctuations in Quarterly Operating Results.  CVD's results of operations
have varied significantly from quarter to quarter. The Company has experienced
an operating loss for each of the last five years. Quarterly operating results
will depend upon several factors, including the timing and amount of expenses
associated with expanding the Company's operations, the conduct of clinical
trials and the timing of regulatory approvals, new product introductions both in
the United States and internationally, the mix between pilot production of new
products and full-scale manufacturing of existing products, the mix between
domestic and export sales, variations in foreign exchange rates, changes in
third-party payors' reimbursement policies and healthcare reform. The Company
does not operate with a significant backlog of customer orders, and therefore
revenues in any quarter are significantly dependent on orders received within
that quarter. In addition, the Company cannot predict ordering rates by
distributors, some of whom place infrequent stocking orders. The Company's
expenses are relatively fixed and difficult to adjust in response to fluctuating
revenues. As a result of these and other factors, the Company expects to
continue to experience significant fluctuations in quarterly operating results,
and there can be no assurance that the Company will be able to achieve or
maintain profitability in the future. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations."
 
     Volatility of Stock Price; Effect of Distribution by EndoSonics. The
distribution of the Company's Common Stock hereunder by EndoSonics could
adversely affect the market price of the Common Stock. Since the Company's
initial public offering in June 1996, the price of the Company's Common Stock
has fluctuated significantly. The Company believes that factors such as the
distribution by Endosonics of a large number of shares of Common Stock,
variations in quarterly results of operations, announcements of technological
innovations or new products by the Company or its competitors, governmental
regulatory action, any future litigation involving the Company, other
developments or disputes with respect to proprietary rights, general trends in
the industry and overall market conditions, and other factors, could cause the
price of the Company's Common Stock to fluctuate, perhaps substantially. In
addition, in recent years the stock market in general, and the market for small
capitalization stocks in particular, has experienced extreme price fluctuations
which have often been unrelated to the operating performance of affected
companies. Such fluctuations could adversely affect the market price of the
Company's Common Stock.
 
     Reliance on Patents and Proprietary Technology; Risk of Patent
Infringement.  While the Company owns certain issued and allowed U.S. patents
and has additional U.S. and foreign patent applications pending, there can be no
assurance that the Company's patent applications will issue as patents or that
any issued patents will provide competitive advantages for the Company's
products or will not be successfully challenged or circumvented by its
competitors. The interventional cardiovascular and peripheral vascular markets
in general and the market for balloon angioplasty catheters (including the type
of catheters offered by CVD) in particular has been characterized by substantial
litigation regarding patent and other intellectual property rights. There can be
no assurance that the Company's products do not infringe such patents or rights.
During 1996, the Company received a notice of potential trademark infringement
regarding the Company's use of the term "focal" in connection with the Company's
balloon angioplasty technology and entered into an agreement which prohibits the
Company from using this term. The Company has since ceased any use thereof. In
the event that any parties assert claims against the Company for patent
infringement and such patents are upheld as valid and enforceable, the Company
could be prevented from utilizing the subject matter claimed in such patents, or
would be required to obtain licenses from the owners of any such patents or
redesign its products or processes to avoid infringement. There can be no
assurance that such licenses would be available or, if available, would be so on
terms acceptable to the Company or that the Company would be successful in any
attempt to redesign its products or processes to avoid infringement. In
addition, foreign intellectual property laws may not provide protection
commensurate with that provided by U.S. intellectual property laws, and there
can be no assurance that foreign intellectual property laws will adequately
protect the Company's
 
                                        8

                                     GG-8
<PAGE>   228
 
intellectual property rights abroad. The Company also relies on trade secrets
and proprietary technology and enters into confidentiality and non-disclosure
agreements with its employees, consultants and advisors. There can be no
assurance that the confidentiality of such trade secrets or proprietary
information will be maintained by employees, consultants, advisors or others, or
that the Company's trade secrets or proprietary technology will not otherwise
become known or be independently developed by competitors in such a manner that
the Company has no practical recourse. Litigation may be necessary to defend
against claims of infringement or invalidity, to enforce patents issued to the
Company or to protect trade secrets, and there can be no assurance that any such
litigation would be successful. Any litigation could result in substantial costs
to, and diversion of resources by, the Company and its officers, which could
have a material adverse effect on the Company's business, financial condition
and results of operations. See "Business -- Patents and Proprietary
Information."
 
     Significant Competition.  Competition in the market for devices used in the
treatment of cardiovascular and peripheral vascular disease is intense, and is
expected to increase. The interventional cardiology market is characterized by
rapid technological innovation and change, and the Company's products could be
rendered obsolete as a result of future innovations. The Company's catheters and
other products under development compete or will compete with products marketed
by a number of manufacturers, including Advanced Cardiovascular Systems, Inc., a
subsidiary of Guidant Corporation ("ACS"), SCIMED Life Systems, Inc., a
subsidiary of Boston Scientific Corporation ("SCIMED"), Johnson & Johnson
Interventional Systems ("JJIS") and Cordis Corporation, subsidiaries of Johnson
& Johnson, Medtronic, Inc., C.R. Bard, Inc. and Schneider USA, a subsidiary of
Pfizer, Inc. Such companies have significantly greater financial, management and
other resources, established market positions, and significantly larger sales
and marketing organizations than does the Company. The Company also faces
competition from manufacturers of other catheter-based devices, vascular stents
and pharmaceutical products intended to treat vascular disease. In addition, the
Company believes that many of the customers and potential customers of the
Company's products prefer to purchase catheter products from a single source.
Accordingly, many of the Company's competitors, because of their size and range
of product offerings, have a competitive advantage over the Company. There can
be no assurance that the Company's competitors will not succeed in developing or
marketing technologies or products that are more clinically effective or cost
effective than any that are being marketed or developed by the Company, or that
such competitors will not succeed in obtaining regulatory approval for
introducing or commercializing any such products prior to the Company. See
"Business -- Competition."
 
     Limited Manufacturing Experience.  The Company's success will depend in
part on its ability to manufacture its products in compliance with ISO 9001, the
FDA's Good Manufacturing Practices ("GMP") regulations, California Department of
Health Services ("CDHS") licensing and other regulatory requirements, in
sufficient quantities and on a timely basis, while maintaining product quality
and acceptable manufacturing costs. The Company began manufacturing certain of
its products at its facilities in July 1995. The Company also introduced a
significant number of new products in 1996. Accordingly, the Company has very
limited experience in manufacturing its products. In addition, on July 15, 1996,
the Company entered into co-distribution agreements with Medtronic, Inc.
("Medtronic") which granted Medtronic certain non-exclusive rights to distribute
the Company's FACT, CAT and ARC catheters. Under the terms of these agreements,
if the Company is unable to meet its delivery obligations with respect to the
purchased catheters, up to 60% of the Company's manufacturing capacity will be
devoted to manufacturing such catheters for Medtronic. The Company has undergone
and expects to continue to undergo regular GMP inspections in connection with
the manufacture of its products at the Company's facilities. The Company's
success will depend, among other things, on its ability to efficiently manage
the simultaneous manufacture of different products and to integrate the
manufacture of new products with existing products. There can be no assurance
that the Company will not encounter difficulties in scaling up production of new
products, including problems involving production yields, quality control and
assurance, component supply and shortages of qualified personnel. The Company's
failure to successfully commence the manufacturing of these new products, or to
increase production volumes of new or existing products in a timely manner,
would materially adversely affect the Company's business, financial condition
and results of operations. Failure to increase production volumes in a timely or
cost-effective manner or to achieve or maintain compliance with ISO 9001, GMP
regulations, CDHS licensing or other regulatory requirements could have a
material adverse effect on the Company's business, financial condition and
results of operations.

     The Company purchases many standard and custom built components from
independent suppliers and subcontracts certain manufacturing processes from
independent vendors. Most of these components and processes are available from
more than one vendor. However, certain manufacturing processes are currently
performed by single vendors. An interruption of performance by any of these
vendors could have a material adverse effect on the Company's ability to
manufacture its products until a new source of supply was qualified and, as a
result, could have an adverse effect on the Company's business, financial
condition and results of operations. See "Business -- Manufacturing" and
"Business -- Government Regulation."
 
     Potential Inability to Manage Growth.  Prior to June 1996, the Company
relied on EndoSonics to perform certain activities on its behalf, including
manufacturing, financial, regulatory and administrative functions. Since July
1995, CVD has conducted its manufacturing operations at its facilities in Irvine
and also currently performs the financial, regulatory and administrative
functions previously performed by EndoSonics. Accordingly, the Company has
experienced a period of significant expansion of its operations that has placed
a significant strain upon its management systems and resources. The Company has
recently implemented a number of new financial and management controls,
reporting systems and procedures. In addition, the Company has recently hired a
significant number of employees and plans to further increase its total head
count. The Company also plans to expand the geographic scope of its customer
base and operations. This expansion has resulted and will continue to result in
substantial demands on the Company's management resources. The Company's ability
to manage future expansion of its operations will require the Company to
continue to improve its financial and management controls, reporting systems and
procedures on a timely basis and to expand, train and manage its employee work
force. There can be no assurance that the Company will be able to do so
successfully. The failure to do so would have a material adverse effect on the
Company's business, financial condition and results of operations.
 
     Government Regulation.  The manufacturing and marketing of the Company's
products are subject to extensive and rigorous government regulation in the
United States and in other countries. The Company believes that its success will
be significantly dependent upon commercial sales of improved versions of its
catheter products. The Company will not be able to market these new products in
the United States unless and until the Company obtains approval or clearance
from the FDA. Foreign and domestic regulatory approvals, if granted, may include
significant limitations on the indicated uses for which a product may be
marketed.
 
     If a medical device manufacturer can establish that a newly developed
device is "substantially equivalent" to a legally marketed Class I or Class II
device, or to a Class III device that the FDA has not called for a premarket
approval ("PMA"), the manufacturer may seek clearance from the FDA to market the
device by filing a premarket notification with the FDA under Section 510(k) of
the Federal Food, Drug, and Cosmetic Act ("510(k)"). All of the 510(k)
clearances received for the Company's catheters were based on substantial
equivalence to legally marketed devices. There can be no assurance that 510(k)
clearance for any future product or significant modification of an existing
product will be granted or that the process will not be unduly lengthy. In
addition, if the FDA has concerns about the safety or effectiveness of any of
the Company's products, it could act to withdraw approval or clearances of those
products or request that the Company present additional data. Any such actions
would have a material adverse effect on the Company's business, financial
condition and results of operations.
 
     If substantial equivalence cannot be established, or if the FDA determines
that the device or the particular application for the device requires a more
rigorous review to assure safety and effectiveness, the FDA will require that
the manufacturer submit a PMA application that must be reviewed and approved by
the FDA prior to sales and marketing of the device in the United States. The PMA
process is significantly more complex, expensive and time consuming than the
510(k) clearance process and always requires the submission of clinical data. It
is expected that certain of the Company's products under development will be
subject to this PMA process. The Company currently has a non-exclusive,
royalty-free right to submit PMA supplement applications utilizing an EndoSonics
PMA as a reference and to manufacture and distribute CVD products as a
supplement to the EndoSonics PMA. This agreement may be terminated in the event
of breach upon 60 days notice by the non-breaching party, subject to the
breaching party's right to cure. In the event of termination, the Company would
be prohibited from submitting new PMA supplements referencing the
 
                                       10

                                    GG-10
<PAGE>   230
 
EndoSonics PMA and would be required to seek independent FDA approval for any
such products, which would have a material adverse effect on the Company's
business, financial condition and results of operations.
 
     The Company is also required to register as a medical device manufacturer
with the FDA and maintain a license with certain state agencies, such as the
CDHS. As such, the Company is inspected on a routine basis by both the FDA and
the CDHS for compliance with GMP regulations. These regulations require that the
Company manufacture its products and maintain related documentation in a
prescribed manner with respect to manufacturing, testing and control activities.
The Company has also undergone and expects to continue to undergo regular GMP
inspections in connection with the manufacture of its products at the Company's
facilities. Further, the Company is required to comply with various FDA
requirements for labeling. The Medical Device Reporting laws and regulations
require that the Company provide information to the FDA on deaths or serious
injuries alleged to have been associated with the use of its devices, as well as
product malfunctions that would likely cause or contribute to death or serious
injury if the malfunction were to recur. In addition, the FDA prohibits an
approved device from being marketed for unapproved applications. CVD has
received FDA approval to market the FACT and ARC catheters, which utilize the
Focus technology, for coronary balloon angioplasty. These catheters are marketed
outside the United States for use in stent deployment. However, without specific
FDA approval for stent deployment, these catheters may not be marketed by the
Company in the United States for such use.
 
     Failure to comply with applicable regulatory requirements can, among other
consequences, result in fines, injunctions, civil penalties, suspensions or loss
of regulatory approvals, product recalls, seizure of products, operating
restrictions and criminal prosecution. In addition, government regulations may
be established in the future that could prevent or delay regulatory clearance or
approval of the Company's products. Delays in receipt of clearances or
approvals, failure to receive clearances or approvals or the loss of previously
received clearances or approvals would have a material adverse effect on the
Company's business, financial condition and results of operations.
 
     The Company is also subject to other federal, state and local laws,
regulations and recommendations relating to safe working conditions, laboratory
and manufacturing practices. The extent of government regulation that might
result from any future legislation or administrative action cannot be accurately
predicted. Failure to comply with regulatory requirements could have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Business -- Products" and "Business -- Government Regulation."
 
     International sales of the Company's products are subject to the
registration requirements of each country. The regulatory review process varies
from country to country and may in some cases require the submission of clinical
data. The Company typically relies on its distributors in such foreign countries
to obtain the requisite regulatory approvals. There can be no assurance,
however, that such approvals will be obtained on a timely basis or at all. In
addition, the FDA must approve the export to certain countries of devices that
require a PMA but are not yet approved domestically. The European Union has
promulgated rules which require that medical products receive by mid-1998 the
right to affix the CE mark, an international symbol of adherence to quality
assurance standards and compliance with applicable European medical device
directives. Failure to receive the right to affix the CE mark will prevent the
Company from selling its products in member countries of the European Union
which would have a material adverse effect on the Company's business, financial
condition and results of operations.
 
     Limited Marketing and Sales Resources; Dependence Upon Strategic
Relationships.  CVD intends to rely primarily on certain strategic
relationships, medical device distributors and its direct sales organization to
distribute its products. The Company's ability to distribute its products
successfully depends in part on the marketing capabilities of its strategic
partners. In recent years there has been significant consolidation among medical
device suppliers as the major suppliers have attempted to broaden their product
lines in order to respond to cost pressures from health care providers. This
consolidation has made it increasingly difficult for smaller suppliers, such as
the Company, to effectively distribute their products without a relationship
with one or more of the major suppliers. The Company is currently marketing
certain of its products through licensing agreements with SCIMED and ACS and
through co-distribution agreements with Medtronic. In addition,
 
                                       11

Fukuda Denshi Company, Ltd. ("Fukuda") is currently the Company's exclusive
distributor in Japan for certain of the Company's products. Fukuda is also
responsible for obtaining regulatory approval for the Company's products in
Japan. The Company recently informed Fukuda of its decision to terminate the
existing Fukuda agreement and does not expect that any obligations will arise as
a result of such termination. The Company expects that Fukuda will continue to
distribute its products at least through 1997. The Company is currently
negotiating with several distributors, including Fukuda, regarding a new
distribution agreement for the Japanese market. The Company's revenue from its
distributor relationships is dependent upon the efforts made by such parties and
there can be no assurance that such efforts will be successful. There can be no
assurance that the Company will be able to maintain or expand its relationships
with its strategic partners or to replace its strategic partners in the event
any such relationship were terminated. In the event of such a termination, the
Company's ability to distribute its products would be materially adversely
affected, which would have a material adverse effect on the Company's business,
financial condition and results of operations.
 
     CVD currently has a limited marketing and sales staff.The Company intends
to expand its direct sales force to market the Company's products expansion.
However, there can be no assurance that CVD will successfully expand its direct
sales and marketing organization, or that if expanded, such organization will be
able to effectively distribute CVD's products. If CVD is unable to achieve
distribution of its products through its direct sales organization, the
Company's business, financial condition and results of operations would be
materially adversely affected.
 
     The Company also has product development relationships with SCIMED and ACS.
SCIMED currently funds certain research and development efforts undertaken by
CVD in the area of combined drug delivery and coronary angioplasty. ACS conducts
development work on the Company's perfusion technology. If CVD is unable to
maintain its relationships with these or future strategic partners its product
development efforts could be materially adversely affected, which would
materially adversely affect the Company's business, financial condition and
results of operations. See "Business -- Marketing and Sales" and "Business --
Strategic Relationships."
 
     Dependence Upon International Sales.  The Company derives, and expects to
continue to derive, a significant portion of its revenue from international
sales. In 1994, 1995 and 1996, the Company's international sales were $1.0
million, $2.1 million and $3.5 million, respectively, or 83%, 59% and 42%,
respectively, of product sales. The Company expects to continue to derive
significant revenue from international sales and therefore a significant portion
of the Company's revenues will continue to be subject to the risks associated
with international sales, including economic or political instability, shipping
delays, changes in applicable regulatory policies, inadequate protection of
intellectual property, fluctuations in foreign currency exchange rates and
various trade restrictions, all of which could have a significant impact on the
Company's ability to deliver products on a competitive and timely basis. Future
imposition of, or significant increases in the level of, customs duties, import
quotas or other trade restrictions, could have an adverse effect on the
Company's business, financial condition and results of operation. In foreign
countries, the Company's products are subject to governmental review and
certification. The regulation of medical devices, particularly in the European
Union, continues to expand and there can be no assurance that new laws or
regulations will not have an adverse effect on the Company's business, financial
condition and results of operations. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations."
 
     Limitations on Third-Party Reimbursement.  In the United States, the
Company's products are purchased primarily by medical institutions, which then
bill various third-party payors, such as Medicare, Medicaid, and other
government programs and private insurance plans, for the health care services
provided to patients. Government agencies, private insurers and other payors
determine whether to provide coverage for a particular procedure and reimburse
hospitals for medical treatment at a fixed rate based on the diagnosis-related
group ("DRG") established by the U.S. Health Care Financing Administration
("HCFA"). The fixed rate of reimbursement is based on the procedure performed,
and is unrelated to the specific devices used in that procedure. If a procedure
is not covered by a DRG, payors may deny reimbursement. In addition, some payors
may deny reimbursement if they determine that the device used in a treatment was
unnecessary, inappropriate or not cost-effective, experimental or used for a
non-approved indication. Reimbursement of
 
                                       12

                                    GG-12
<PAGE>   232
 
interventional procedures utilizing the Company's products is currently covered
under a DRG. There can be no assurance that reimbursement for such procedures
will continue to be available, or that future reimbursement policies of payors
will not adversely affect the Company's ability to sell its products on a
profitable basis. In addition, reimbursement may be denied if the product use is
not in accordance with approved FDA labeling. Failure by hospitals and other
users of the Company's products to obtain reimbursement from third-party payors,
or changes in government and private third-party payors' policies toward
reimbursement for procedures employing the Company's products, would have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business -- Third-Party Reimbursement."
 
     Control by Existing Stockholder; Limitations on Pooling-of-Interests
Accounting in Merger Transactions. Immediately prior to the distribution of the
Shares by EndoSonics pursuant to this prospectus, EndoSonics owned approximately
44% of the Company's outstanding Common Stock. After such distribution,
EndoSonics is expected to own approximately 28.67% of the Company's outstanding
Common Stock. As a result, EndoSonics is able to elect at least one member to
the Company's five person board of directors and has the ability to influence
the Company and influence its affairs and the conduct of its business. Such
concentration of ownership may have the effect of delaying, deferring or
preventing a change in control of the Company. In accordance with applicable
accounting standards, the Company is prohibited from accounting for a merger
transaction, of or by the Company, as a pooling-of-interests for a period of two
years following June 25, 1996, the date on which EndoSonics ceased to control
50% of the outstanding voting Common Stock of the Company. As a result, any
business combination consummated prior to the expiration of such period would
have to be accounted for using the purchase method. Under the purchase method,
the excess of the purchase price over the net book value of the assets acquired
would be amortized to expense, which could result in a significant negative
impact on the acquiror's results of operations and, therefore, reduce the
attractiveness of, or the price paid in, a particular acquisition transaction.
 
     On January 27, 1997, EndoSonics announced that the EndoSonics Board of
Directors had approved a dividend distribution of one CVD share for every 25
EndoSonics shares. The distribution is expected to take place in the second half
of 1997 to EndoSonics stockholders then of record. The exact record date and
date of distribution have not yet been determined.
 
     Dependence Upon Key Personnel.  The Company depends to a significant extent
upon key management and technical personnel. The Company's growth and future
success will depend in large part upon its ability to hire, motivate and retain
highly qualified personnel. Competition for such personnel is intense and there
can be no assurance that the Company will be successful in hiring, motivating or
retaining such qualified personnel. The loss of key personnel or the inability
to hire or retain qualified personnel could have a material adverse effect on
the Company's business, financial condition and results of operations. See
"Business -- Marketing and Sales," "Business -- Employees" and "Management."
 
     Potential Product Liability; Limited Insurance.  The Company faces the risk
of financial exposure to product liability claims. The Company's products are
often used in situations in which 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.
The Company is currently covered under a product liability insurance policy with
coverage limits of $2.0 million per occurrence and $2.0 million per year in the
aggregate. There can be no assurance that the Company's product liability
insurance is adequate or that such insurance coverage will remain available at
acceptable costs. There can be no assurance that the Company will not incur
significant product liability claims in the future. A successful claim brought
against the Company in excess of its insurance coverage could have a material
adverse effect on the Company's business, financial condition and results of
operations. Additionally, adverse product liability actions could negatively
affect the reputation and sales of the Company's products and the Company's
ability to obtain and maintain regulatory approval for its products and
substantially divert the time and effort of management away from the Company's
operations.
 
     Shares Eligible for Future Sale; Potential Adverse Effect on Market
Price.  Sales of Common Stock in the public market during and after this
offering could adversely affect the market price of the Common Stock.

As of April 15, 1997, the Company had 9,103,459 shares outstanding. Including
all of the Shares registered for sale hereby, 5,610,054 of the Company's
outstanding shares are freely tradable without restriction. Approximately
2,531,768 additional shares are eligible for sale, including 1,809,768 shares
held by EndoSonics, not registered for sale hereunder, and 646,000 shares held
by SCIMED. Sales of any such shares in the public market could adversely affect
the market price of the Common Stock. The Company has also registered 1,200,000
shares of Common Stock reserved for issuance under the Company's 1996 Stock
Option/Stock Issuance Plan and 200,000 shares under the Company's Employee Stock
Purchase Plan. As of April 15, 1997, there were outstanding options under the
Company's stock option plans to acquire approximately 1,188,000 shares. SCIMED
is entitled to certain demand piggyback registration rights with respect to its
shares. If SCIMED, by exercising its demand registration rights, causes a large
number of shares to be registered and sold in the public market, such sales
could have an adverse effect on the market price for the Common Stock. If the
Company were required to include in a Company-initiated registration shares held
by SCIMED pursuant to the exercise of its piggyback registration rights, such
sales may have an adverse effect on the Company's ability to raise needed
capital. See "Shares Eligible for Future Sale."
 
     Effect of Certain Charter Provisions; Anti-takeover Effects of Certificate
of Incorporation, Bylaws and Delaware Law.  The Company's Board of Directors has
the authority to issue up to 5,000,000 shares of Preferred Stock and to
determine the price, rights, preferences, privileges and restrictions, including
voting rights, of those shares without any further vote or action by the
stockholders. The rights of the holders of Common Stock will be subject to, and
may be adversely affected by, the rights of the holders of any Preferred Stock
that may be issued in the future. The issuance of Preferred Stock could have the
effect of making it more difficult for a third party to acquire a majority of
the outstanding voting stock of the Company. In addition, the Company is subject
to the anti-takeover provisions of Section 203 of the Delaware General
Corporation Law, which will prohibit the Company from engaging in a "business
combination" with an "interested stockholder" for a period of three years after
the date of the transaction in which the person became an interested
stockholder, unless the business combination is approved in a prescribed manner.
The application of Section 203 also could have the effect of delaying or
preventing a change of control of the Company. Further, certain provisions of
the Company's Certificate of Incorporation and Bylaws and of Delaware law could
delay or make more difficult a merger, tender offer or proxy contest involving
the Company, which could adversely affect the market price of the Company's
Common Stock. See "Description of Capital Stock."
 
     Absence of Dividends.  The Company has never paid any cash dividends on the
Common Stock and does not anticipate paying any cash dividends on the Common
Stock in the foreseeable future. See "Dividend Policy."

EndoSonics, Merger Sub and Cardiometrics.
 
     All of the Shares were originally issued by the Company to EndoSonics in
connection with the acquisition by EndoSonics of all of the outstanding capital
stock of the Company pursuant to an Agreement and Plan of Reorganization between
EndoSonics and the Company dated June 9, 1993, and in connection with the
acquisition by EndoSonics of 400,000 shares of the Company's Series B Preferred
Stock on March 29, 1996, which converted into 800,000 shares of Common Stock
upon the consummation of the Company's initial public offering. The Shares were
issued pursuant to an exemption from the registration requirements of the
Securities Act, provided by Section 4(2) thereof. The Shares are being
registered by the Company pursuant to a registration rights agreement by and
between the Company and EndoSonics entered into in connection with the
acquisition of Cardiometrics by EndoSonics. EndoSonics has agreed to pay all
reasonable fees and expenses incident to the filing of this Registration
Statement.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     This Prospectus contains certain forward-looking statements. The Company's
actual results may differ materially from those described in the forward-looking
statements. Investors should carefully consider the information set forth under
the heading "Risk Factors" in addition to the other information contained in
this Prospectus before purchasing the Common Stock offered hereby.
 
OVERVIEW
 
     CVD designs, develops, manufactures and markets catheters used to treat
certain vascular diseases. The Company's patented catheters utilize its Focus
and M(3) technologies to deliver therapeutic radial pressure, stents, drugs or
contrast media and improved blood flow during angioplasty and stent placement
procedures. To date, the majority of the Company's revenue has been derived from
sales of its angioplasty and angioplasty-related catheters.
 
     From inception (March 16, 1992) through the first quarter of 1994, the
Company's operations were limited and consisted primarily of research and
development and other start-up activities. On June 15, 1992, EndoSonics acquired
a 40% interest in CVD in exchange for $0.5 million in cash. Pursuant to an
Agreement and Plan of Reorganization between EndoSonics and CVD signed on June
9, 1993, EndoSonics acquired all of the outstanding capital stock of CVD in
exchange for $0.3 million in cash and 250,000 shares of EndoSonics' Common Stock
with an aggregate market value of $1.6 million. The acquisition by EndoSonics
resulted in a new basis for CVD's assets and liabilities. Accordingly, the
purchase price paid by EndoSonics has been allocated to CVD's identifiable
assets and liabilities, including $2.0 million to acquired in-process research
and development, which was immediately expensed, as no CVD products had received
regulatory approval and the technology did not have alternative future uses.
Pursuant to the terms of the Agreement and Plan of Reorganization, in June 1995,
EndoSonics became obligated to issue 50,000 shares of its Common Stock with an
aggregate market value of $0.5 million, to the former shareholders of CVD
because the market price of EndoSonics' stock did not exceed a specified price
for a specified period during the two-year period following the acquisition. The
fair value of such shares was charged to acquired in-process technology. In
March 1996, EndoSonics purchased 400,000 shares of CVD's Series B Preferred
Stock for a purchase price of $8.0 million, which converted into 800,000 shares
of Common Stock upon the consummation of the initial public offering. See
"Certain Transactions -- Relationship with Endosonics Corporation."
 
     In September 1994, CVD and SCIMED entered into a Stock Purchase and
Technology License Agreement to develop and license CVD's patented combination
balloon angioplasty/site-specific drug delivery technology (the Transport
product line) for use in the coronary vessels. Through December 31, 1996 the
Company had received in the aggregate approximately $2.2 million in license
fees, research and development funding and technical assistance from SCIMED
under this agreement. SCIMED also purchased a 19% equity position in the Company
for a purchase price of $2.5 million. See "Business -- Strategic Relationships."
 
     In January 1995, the Company and ACS entered into an agreement pursuant to
which the Company acquired certain rights to ACS' SmartNeedle Technology,
subject to the payment of certain royalties. The parties subsequently confirmed
their understanding with respect to certain matters in a second agreement dated
March 4, 1996 (collectively, the "ACS Agreements"). Pursuant to the ACS
Agreements, ACS was granted the option to acquire the exclusive worldwide rights
to certain CVD perfusion technology, which ACS exercised on February 14, 1996.
In exchange for this perfusion technology, ACS is obligated to make milestone
and minimum annual royalty payments to CVD, and also has certain obligations to
develop and market the perfusion technology. Through December 31, 1996 the
Company had received approximately $0.35 million in milestone payments under the
ACS Agreements. See "Business -- Strategic Relationships."
 
     The Company currently sells its products through a combination of medical
device distributors and a limited number of direct sales personnel. The Company
is a party to three agreements for the U.S. distribution of products
incorporating its Focus and M(3) technologies. CVD currently distributes certain
products in Japan through an exclusive distribution agreement with Fukuda. The
Company recently informed Fukuda of its decision to terminate the existing
Fukuda agreement. The Company expects that Fukuda will continue to
 
                                       18

distribute its products at least through 1997. The Company is currently
negotiating with several distributors, including Fukuda, regarding a new
distribution agreement for the Japanese market. CVD also has distribution
agreements with 25 companies covering 41 countries outside the United States and
Japan. See "Business -- Strategic Relationships."
 
     On July 15, 1996, CVD and Medtronic, Inc. entered into agreements providing
for the co-distribution by Medtronic of the Company's balloon angioplasty
catheters. These catheters employ the Company's patented Focus Technology. Under
the agreements, Medtronic will purchase a minimum number of angioplasty
catheters manufactured by the Company for distribution worldwide for a period of
up to three years. If the Company is unable to meet its delivery obligations
with respect to the purchased catheters, up to 60% of the Company's
manufacturing capacity will be devoted to manufacturing such catheters for
Medtronic. Specific products to be distributed by Medtronic will differ in
individual country markets. The Company will continue to sell Focus Technology
products through its own direct and indirect sales force network. These products
are currently sold under the names, FACT, CAT and ARC. See
"Business -- Strategic Relationships."
 
RESULTS OF OPERATIONS
 
  YEARS ENDED DECEMBER 31, 1995 AND DECEMBER 31, 1996
 
     Sales Revenue. Sales revenue increased to $8.4 million in 1996 from $3.5
million in 1995, representing an increase of 140%. The increase resulted
primarily from increased sales volume of the Company's existing and new Focus
catheters (112%), and, to a lesser extent, the introduction of other new
products (13%). Sales of products through Medtronic under the Company's
co-exclusive distribution agreement and sales of products in Japan through the
Company's exclusive distribution relationship with Fukuda accounted for 22% and
15%, respectively, of total product sales in 1996.
 
     License Fee and Other Revenue. License fee and other revenue increased to
$0.2 million in 1996 from $0.0 million in 1995. This increase resulted from
revenues from a license agreement with ACS. See "Business -- Strategic
Relationships."
 
     Contract Revenue. Contract Revenue was $0.2 million in 1996 and $0.6
million in 1995. This decrease stemmed from reduced technology development and
other support from SCIMED. See "Business -- Strategic Relationships."
 
     Cost of Sales. Cost of sales increased to $4.1 million in 1996 from $2.1
million in 1995. This increase resulted primarily from increased manufacturing
volumes related to increased product sales. In July 1995, the Company
transferred its product manufacturing from EndoSonics' facility to the Company's
facility in Irvine, California.
 
     Charge for Acquired In-process Research and Development. The Company
incurred a charge of $2.1 million in 1996 in connection with the acquisition of
Intraluminal Devices, Inc. ("IDI"). The excess of the purchase price of IDI over
the fair market value of the net assets acquired was recorded as acquired in-
process research and development. The acquired in-process research and
development was immediately written off as IDI was in the development stage and
had not yet received regulatory approval for any of its products at the time of
the acquisition.
 
     Research and Development. Research and development increased to $3.6
million in 1996 compared to $1.7 million in 1995, representing an increase of
112%. This increase resulted primarily from expenditures on the development of
vascular access and Focus technology products. The Company believes it must
maintain a substantial commitment to research and development to remain
competitive and expects expenditures related to research and development to
increase.
 
     Marketing and Sales. Marketing and sales expenses increased to $3.4 million
in 1996 from $1.5 million in 1995, representing an increase of 127%. This
increase resulted mainly from the expansion of the Company's direct sales force
in the United States and marketing expenses related to the product launch of the
FACT and ARC catheters. The Company expects to expand and expects expenses
associated with these activities to increase in the future as it expands.

                                    GG-19
<PAGE>   239
 
     General and administrative. General and administrative expenses increased
to $1.5 million in 1996 from $1.3 million in 1995, representing an increase of
15%. The added costs were primarily due to additions in administrative staff and
the added costs of operating as a public company.
 
     Other Income. Other income, principally interest income, increased to $1.3
million in 1996 from $0.1 million in 1995. The increase resulted from the
investment of the net proceeds of the Company's initial public offering which
amounted to approximately $42.8 million.
 
  YEARS ENDED DECEMBER 31, 1994 AND DECEMBER 31, 1995
 
     Sales Revenue. Sales revenue increased to $3.5 million in 1995 from $1.2
million in 1994, representing an increase of 196%. Sales revenue in 1994
resulted primarily from sales of the Company's Transport products, which were
subsequently licensed to SCIMED in 1995. The Company no longer receives sales
revenue for the Transport. Sales revenue in 1995 was due to sales of the
Company's CAT catheter, which was introduced in the first quarter of 1995, and
sales of the SmartNeedle vascular access products beginning in the second
quarter of 1995. Sales of products in Japan through the Company's exclusive
distribution relationship with Fukuda accounted for 18% of the Company's revenue
in 1995. In addition, sales to JJIS accounted for 12% of the Company's revenue
in 1995.
 
     License Fee and Other Revenue. License fee and other revenue decreased to
$0.0 million in 1995 from $1.0 million in 1994. License fee and other revenue
represents amounts earned under the aforementioned agreement with SCIMED. Future
revenue under this agreement will be derived primarily from royalties earned on
SCIMED's sales of the Transport.
 
     Contract Revenue. Contract revenue was $0.6 million in 1995 and $0.2
million in 1994. Contract revenue was earned under the aforementioned agreement
with SCIMED.
 
     Cost of Sales. Cost of sales increased to $2.1 million in 1995 from $0.8
million in 1994, representing an increase of 142%. This increase resulted
primarily from increased manufacturing volumes related to increased product
sales. In July 1995, the Company transferred its product manufacturing from
EndoSonics' facility to the Company's facility in Irvine, California.
 
     Charge for Acquired In-process Research and Development. The Company
incurred a charge of $0.5 million in 1995 in connection with the 1995 payment by
EndoSonics of additional consideration related to the original acquisition by
EndoSonics of CVD stock. This portion of the excess of the purchase price of CVD
over the fair market value of the net assets acquired was recorded as in-process
research and development. The acquired in-process research and development was
immediately written off as CVD was in the development stage and had not yet
received regulatory approval for any of its products at the time of the
acquisition.
 
     Research and Development. Research and development expenses increased to
$1.7 million in 1995 compared to $1.2 million in 1994, representing an increase
of 37%. This increase was due primarily to increased expenditures related to
development of the Company's Focus and M(3) technology products. These expenses
also increased due to clinical trials and studies related to the Focus
technology products. The Company believes that it must maintain a substantial
commitment to research and development to remain competitive and expects
expenditures related to research and development to increase.
 
     Marketing and Sales. Marketing and sales expenses increased to $1.5 million
in 1995 from $0.7 million in 1994, representing an increase of 104%. This
increase resulted from the development and expansion of the Company's U.S. sales
organization and marketing expenses related to the product launch of the
SmartNeedle products. The Company expects to expand its marketing and sales
force and expects expenses associated with marketing and sales to increase in
the future.
 
     General and Administrative. General and administrative expenses increased
to $1.3 million in 1995 from $0.6 million in 1994, representing an increase of
127%. This increase resulted from expenses incurred as the Company commenced
operations as an independent entity, rather than as a division of EndoSonics,
and

                                    GG-20
<PAGE>   240
 
included the addition of a full-time Chief Executive Officer, increased legal
and accounting expenses, increased support staff and increased travel expenses.
 
     Other Income. Total other income remained relatively constant in 1995 from
1994.
 
  FIRST QUARTER OF 1997 COMPARED TO THE SAME PERIOD IN 1996
 
     Sales Revenues.  Revenue for the first quarter of 1997 increased 48% to
$3.0 million compared to $2.0 million for the first quarter of 1996. The
increase resulted primarily from increased sales volume of the Company's
existing and new Focus catheters (42%), and, to a lesser extent, the
introduction of other new products (22%).
 
     Gross Profit.  The gross profit percentage for the first quarter of 1997
decreased to 53% compared to 54% for the same period of 1996. In the first
quarter of 1996, total revenues included approximately $0.3 million of contract
revenues and license fee income that had no associated cost of sales. These
revenues and fees represented 12% of total revenues for that quarter. In the
first quarter of 1997, the Company had no contract revenues or licensing fee
income.
 
     Research and Development.  Research, development and clinical expenses
increased by 58% to $1.0 million in the quarter ended March 31, 1997 from $0.6
million in the quarter ended March 31, 1996. The primary reason for this
increase was additional spending on development of the Company's line of
coronary stent products and FOCUS technology angioplasty catheters.
 
     Marketing and Sales.  Marketing and sales expenses rose 134% to $1.4
million, up $0.8 million in the quarter ended March 31, 1997, compared to $0.6
million in the same period of 1996. This increase reflects the investment the
Company is making to build its sales and marketing infrastructure by adding
additional personnel and developing additional distributor relationships.
 
     General and Administrative.  General and administrative expenses increased
by 52% to $0.4 million for the quarter ended March 31, 1997 from $0.3 million
for the same quarter in 1996. The increase was due primarily to the addition of
additional administrative staff and the added costs of operating as a public
company.
 
     Other Income.  Interest income rose to $0.6 million in the first quarter of
1997 compared with $0.0 million in the same period of 1996. The increase was due
to the investment of funds received from the initial public offering in June
1996.
 
     The Company has experienced an operating loss for each of the last three
years and expects to continue to incur operating losses through at least 1997.
CVD's results of operations have varied significantly from quarter to quarter.
Quarterly operating results will depend upon several factors, including the
timing and amount of expenses associated with expanding the Company's
operations, the conduct of clinical trials and the timing of regulatory
approvals, new product introductions both in the United States and
internationally, the mix between pilot production of new products and fullscale
manufacturing of existing products, the mix between domestic and export sales,
variations in foreign exchange rates, changes in third-party payors'
reimbursement policies and healthcare reform. The Company does not operate with
a significant backlog of customer orders, and therefore revenues in any quarter
are significantly dependent on orders received within that quarter. In addition,
the Company cannot predict ordering rates by distributors, some of whom place
infrequent stocking orders. The Company's expenses are relatively fixed and
difficult to adjust in response to fluctuation revenues. As a result of these
and other factors, the Company expects to continue to experience significant
fluctuations in quarterly operating results, and there can be no assurance that
the Company will be able to achieve or maintain profitability in the future.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Since inception, the Company has financed its operations primarily from the
sale of its equity securities, advances from EndoSonics, licensing its
technologies and through international product distribution agreements. Prior to
the Company's initial public offering, the Company had raised an aggregate of
 
                                       21

                                    GG-21
<PAGE>   241
 
approximately $11.4 million from the private sales of preferred and common stock
and $2.7 million in working capital from EndoSonics, which was repaid to
EndoSonics during the third quarter of 1996. In the third quarter of 1996, the
Company closed its initial public offering of common stock, resulting in net
proceeds of $42.8 million after deducting underwriting discounts and commissions
and other expenses of the offering. For the years ended December 31, 1996, 1995
and 1994, and the three month periods ended March 31, 1997 and 1996, the
Company's net cash used in operating activities was $6.2 million, $2.1 million,
$1.5 million, $2.2 million and $0.8 million, respectively. These increases were
primarily due to funding of operating losses and the charges for acquired
in-process research and development.
 
     On March 31, 1997, CVD had cash, cash equivalents and marketable securities
available for sale of $40.8 million. The Company expects to incur substantial
costs related to, among other things, clinical testing, product development,
marketing and sales expenses, and to utilize increased levels of working capital
to finance its accounts receivable and inventories, prior to achieving positive
cash flow from operations. The Company anticipates that its existing capital
resources will be sufficient to fund its operations at least through June 30,
1998. CVD's future capital requirements will depend on many factors, including
its research and development programs, the scope and results of clinical trials,
the regulatory approval process, the costs involved in intellectual property
rights enforcement or litigation, competitive products, the establishment of
manufacturing capacity, the establishment of sales and marketing capabilities,
and the establishment of collaborative relationships with other parties. The
Company may need to raise funds through additional financings, including private
or public equity offerings and collaborative arrangements with existing or new
corporate partners. There can be no assurance that funds will be raised on
favorable terms, or at all. If adequate funds are not available, the Company may
be required to delay, scale back or eliminate one or more of its development
programs or obtain funds through arrangements with collaborative partners or
others that may require the Company to grant rights to certain technologies or
products that the Company would not otherwise grant.
 
     Trade accounts receivable, net, increased 21% to $2.7 million as of March
31, 1997, compared with $2.3 million at December 31, 1996. The increase stemmed
from an increase in the sales level compared to the prior quarter. Specifically,
sales for the first quarter of 1997 were $3.0 million, while sales for the
fourth quarter of 1996 were $2.5 million.
 
     Inventories rose 34% to $3.9 million as of March 31, 1997, compared with
$2.9 million at December 31, 1996, to meet current sales demand. Accounts
payable increased 21% to $0.9 million at March 31, 1997, compared with $0.8
million at the end of 1996, due to an increase in expenditures to support higher
sales.
 
     Property and equipment, net, increased 11% from $1.2 million at December
31, 1996 to $1.3 million at March 31, 1997. The Company increased its investment
in capital assets during the first three months of 1997 to support rising
production and research and development efforts.

OVERVIEW
 
     CardioVascular Dynamics, Inc. ("CVD" or the "Company") designs, develops,
manufactures and markets catheters used to treat certain vascular diseases. The
Company's catheters are used in conjunction with angioplasty and other
interventional procedures such as vascular stenting and drug delivery. The
Company's proprietary Focus and Multiple Microporous Membrane ("M(3)")
technologies enable physicians to deliver therapeutic radial force, stents,
drugs or contrast media accurately and effectively to the treatment site, and
also allow the perfusion of blood during an interventional procedure. The
Company believes that the combination of these technologies on a multiple
purpose catheter enables physicians to more effectively perform challenging
interventional procedures, which may result in improved treatment outcomes and
lower costs. The Company's catheters are designed to address three principal
challenges facing cardiologists: restenosis of a treated vessel, chronic total
occlusions and acute reclosure of a vessel during or soon after a procedure. The
Company has eleven issued U.S. patents covering certain aspects of its catheter
technologies.
 
INDUSTRY BACKGROUND
 
     Cardiovascular disease, the leading cause of death in the United States, is
caused principally by atherosclerosis. Atherosclerosis is a progressive and
degenerative vascular disease in which cholesterol and other fatty materials are
deposited on the walls of blood vessels, forming a build-up known as plaque. The
accumulation of plaque narrows the interior of the blood vessels, thereby
reducing blood flow. Atherosclerosis in the coronary arteries can lead to heart
attack and death. In peripheral vessels, atherosclerosis can lead to decreased
mobility, loss of function and other complications of the affected limb.
 
     Traditional treatments for atherosclerosis include drug therapy and
open-heart bypass surgery. Currently available drug therapies may alleviate some
of the symptoms of atherosclerosis but may be ineffective with severe disease
and may cause adverse side effects. Traditional open-heart bypass surgery
involves opening a patient's chest, cutting through the sternum, connecting the
patient to a heart/lung machine and grafting a blood vessel to redirect blood
flow around the occluded portion of an artery. Such a procedure is costly and
generally requires up to a week of hospitalization and an extensive recovery
period. In addition, certain companies are developing methods and devices for
performing bypass surgery using minimally invasive techniques.
 
     The need for less invasive and less costly treatments for atherosclerosis
has led to the development of minimally invasive catheter-based treatments such
as balloon angioplasty ("PTCA" in the coronary arteries and "PTA" in the
peripheral arteries), atherectomy and laser angioplasty. These treatments
involve making a small incision in a patient's leg to access an artery and
inserting a catheter. Balloon angioplasty is a procedure in which a
balloon-tipped catheter is guided to the lesion (the site of the plaque) and
then inflated and deflated several times, delivering therapeutic radial force,
which cracks or reshapes the plaque and increases blood flow. Balloons used to
perform such procedures are characterized by their response to pressure as
either compliant (balloon diameter increases with increased pressure) or
non-compliant (balloon diameter remains relatively constant with increasing
pressure). Conventional balloon technology only allows the balloon to expand to
a single, uniform diameter along the length of the balloon. Because of
variations in vessel diameters at the lesion site, multiple catheters are often
required to treat a single lesion. In addition, conventional catheter
technologies often are unable to limit the delivery of therapeutic radial force
specifically to the lesion site and may damage the adjacent vessel wall.
Conventional catheter technology also interrupts blood flow when the balloon is
inflated, which may cause tissue damage, heart attack or death, particularly if
the balloon inflation required is of significant duration. Existing catheters
that do not perfuse blood require cardiologists to inflate and deflate the
balloon multiple times which may reduce the clinical effectiveness of the
treatment. Other treatments include the use of atherectomy catheters, which cut
or grind away the plaque, and laser angioplasty catheters, which deliver laser
energy to break down the plaque.
 
     Although catheter-based interventional therapies are generally successful
in initially increasing blood flow, studies indicate that after a traditional
coronary balloon angioplasty up to 50% of treated patients
 
                                       23

                                    GG-23
<PAGE>   243
 
experience restenosis (generally defined as a 50% or greater reduction in the
lumen, or interior, diameter of the treated vessel at the lesion site). In
addition, studies show that 5% to 8% of elective coronary balloon angioplasty
patients may experience acute reclosure of the treated vessel. Acute reclosure
is an increase in the severity of the vessel closure accompanied by a reduction
in blood flow within the vessel as a consequence of the intervention which
occurs within 24 hours of the procedure. A study has also indicated that
angioplasty of chronic total occlusions represents 10% to 20% of all coronary
angioplasty procedures. A chronic total occlusion is a complete blockage of the
vessel preventing blood flow beyond the lesion site. The Company believes that
these challenges are inadequately addressed with existing, single function,
uniform diameter angioplasty balloons. However, while the Company believes that
its products address certain disadvantages of existing catheter technology,
limitations remain in the use of balloon angioplasty to treat atherosclerosis.
The Company's products may not be suitable for the treatment of all forms of
atherosclerosis. For example, in many cases the existence of a total occlusion
limits treatment options to bypass surgery.
 
     Coronary stents have recently emerged as an additional minimally invasive
device for the treatment of atherosclerosis. Stents were used initially for
treating failed angioplasty procedures and acute or threatened vessel closures.
However, improved techniques for the deployment and assessment of stents,
changes in accompanying drug therapy and advancements in stent technology have
led to the increased use of stents to treat restenosis. After an angioplasty,
atherectomy or other catheter-based treatment, a stent, which is a small metal
prostheses, is then advanced along a guidewire to the desired position, expanded
against the inside of the vessel wall and left in place. While certain stents
are self-expanding, most are deployed through the expansion of a compliant or
semi-compliant balloon. Following this deployment, physicians have increasingly
adopted the technique of using a second, high pressure non-compliant balloon to
further expand the stent. Despite advancements in stent technology, existing
compliant or semi-compliant balloons used for stent delivery are designed to
achieve a uniform diameter along the length of the balloon, and their use may
result in sub-optimal stent deployment or damage of the vessel adjacent to the
lesion.
 
     Although there continue to be significant technological and clinical
advances in the treatment of cardiovascular disease, challenges remain in
cost-effectively treating certain conditions, including restenosis of a treated
vessel, chronic total occlusions and acute reclosure of a vessel during or soon
after a procedure. The Company believes that these challenges are inadequately
addressed with existing, single function, uniform diameter angioplasty balloons.
 
THE CARDIOVASCULAR DYNAMICS SOLUTION
 
     CVD has utilized its core proprietary technologies to develop catheters
that provide clinical and cost benefits in the treatment of vascular disease.
The Company's proprietary Focus and M(3) technologies, which may be utilized
alone or in combinations on a single catheter, enable physicians to deliver
therapeutic radial force, stents, drugs or contrast media accurately to the
treatment site, and also allow the perfusion of blood during an interventional
procedure. The Company believes that the combination of these technologies on a
single catheter enables physicians to cost-effectively treat vascular diseases
by reducing the cost of those procedures that require more than one catheter.
 
     The Company's patented Focus technology combines compliant and
non-compliant balloon materials on a single catheter, creating a balloon that
has an adjustable, larger center diameter with fixed, smaller diameters at each
end. These characteristics allow a single balloon to expand to multiple
diameters, enabling the physician to perform interventional procedures in
vessels of varying diameters and anatomical locations. In particular, the Focus
technology enables cardiologists to incrementally increase the angioplasty
balloon's center diameter during a procedure to enhance the effectiveness of the
treatment in vessels that have uncertain or varying diameters or irregular
plaque deposits. Use of conventional catheter technology in these situations may
require multiple catheters to achieve a similar outcome. The Focus technology
may also reduce the incidental damage to the artery wall adjacent to the lesion,
as the therapeutic radial force is applied more accurately to the treatment
site.
 
     The Company's proprietary M(3) technology combines multiple membranes of
polymeric balloon material to form a single balloon that enables the accurate
delivery of drugs or contrast agents to the lesion or thrombus
 
                                       24

                                    GG-24

site. Drugs are utilized by cardiologists to reduce the occurrence of restenosis
and acute reclosure, and to dissolve blood clots. Typically, therapeutic drug
delivery is accomplished by means of an intravenous injection, a method that
requires larger amounts of drug than is clinically required because the drug is
diffused throughout the body. The accurate delivery of drugs to the treatment
site may enhance the effectiveness of these pharmacological agents, thereby
reducing the quantity of drug required to achieve an acceptable clinical outcome
and potentially reducing the incidence of acute reclosure and restenosis. In
addition, the Company has developed M(3) catheters with multiple inner lumens,
providing the cardiologist with flexibility in drug treatment regimens. The
multiple lumens of the catheter may also be used to deliver contrast media for
angiographic viewing when advancing a catheter along a totally occluded vessel.
Traditional catheters must be removed to inject contrast media into a total
occlusion. Finally, the M(3) technology can be utilized to provide perfusion of
blood during an interventional procedure. The interruption in blood flow caused
by a conventional angioplasty balloon may cause tissue damage, heart attack or
death, particularly if the balloon inflation required is of significant
duration. Existing catheters that do not perfuse blood require cardiologists to
inflate and deflate the balloon multiple times for shorter periods which may
reduce the clinical effectiveness of the treatment.
 
STRATEGY
 
     The Company's objective is to be a leader in the design, development and
commercialization of clinically effective solutions for certain vascular
diseases. While there can be no assurance that the Company will achieve this
objective, following are the key elements of CVD's strategy.
 
          Maintain Technological Leadership and Product Technology
     Advantages.  CVD's strategy is to be a technological leader in the
     treatment of vascular diseases through product innovation. The Company
     believes that its products have significant performance advantages over
     alternative catheter technologies. The Company intends to maintain and
     advance its position of technology leadership through aggressive research,
     development and clinical testing programs. The Company owns eleven issued
     U.S. patents related to key aspects of its catheter technologies and has
     applied for additional U.S. patents as well as foreign patent protection.
 
          Market Products through Independent Distributors and a Direct
     Salesforce.  The Company currently markets its products through a
     combination of independent distributors and a dedicated salesforce. The
     Company currently employs eighteen direct sales people, fourteen of whom
     operate in the United States, and four of whom operate internationally. The
     Company plans to significantly expand its direct sales force over the next
     eighteen months. CVD utilizes independent distributors internationally and
     in selected U.S. markets. In addition, the Company entered into
     co-distribution agreements with Medtronic, under which Medtronic will
     purchase a minimum number of the Company's angioplasty catheters for
     distribution worldwide for a period of up to three years.
 
          Establish Relationships with Clinical Opinion Leaders.  The Company
     believes that establishing relationships with clinical opinion leaders in
     the field of interventional cardiology may raise the awareness of the
     clinical and cost benefits of the Company's products. CVD is currently
     conducting or planning two post-marketing clinical studies with certain of
     such leaders. In addition, the Company consults with certain cardiologists
     who assist the Company in ongoing product and technology development.
 
          Target International Markets.  CVD seeks to commercialize its products
     in those international markets where regulatory approval can be obtained
     more quickly than in the United States. This enables CVD to generate
     revenue more quickly from its product development efforts, to fund its
     operations and increase awareness of its products within the international
     interventional cardiology community.
 
          Establish Strategic Partnerships.  The Company attempts to identify
     and evaluate potential strategic relationships where such relationships may
     complement and expand the Company's research, development, sales and
     marketing capabilities. The Company believes that such strategic
     relationships may facilitate the market acceptance of the Company's
     products.

(2) Not approved in the United States for stent delivery. The marketing of this
    product in the United States for such use will require the Company to obtain
    a PMA supplement approval. The Company is not currently seeking such
    approval.
 
     Focus Catheters.  The Company's Focus products have a catheter balloon that
has an adjustable, larger center diameter and smaller, fixed, distal and
proximal diameters. This characteristic provides increased utility in a variety
of therapeutic treatments and anatomical locations. Existing uniform diameter
catheters require cardiologists to use multiple balloons to treat vessels of
varying diameters, resulting in unnecessary costs. In
 
                                       26

                                    GG-26
<PAGE>   246
 
addition, the Focus catheters may deliver stents more effectively by focusing
the radial deployment force on the stented section, rather than along the entire
balloon, which may reduce the damage to the adjacent vessel.
 
     M(3) Catheters.  The Company's M(3) catheters offer cardiologists the
ability to deliver drugs or contrast media to the treatment site accurately and
enable the perfusion of blood during angioplasty procedures. These capabilities
may be combined on an interventional catheter to provide cardiologists the
functionality of multiple catheters, in a single, cost-effective device. The
accurate delivery of drugs to the treatment site may enhance the effectiveness
of these pharmacological agents and may reduce the quantity of drug required to
achieve an acceptable outcome. Drugs are utilized by cardiologists to reduce the
occurrence of restenosis and acute reclosure, and to dissolve blood clots.
Typically, therapeutic drug delivery is accomplished by means of an intravenous
injection, a method that requires larger amounts of drug than is clinically
required because the drug is diffused throughout the body. The Company's M(3)
technology enables cardiologists to deliver drugs directly to the treatment site
through a catheter's lumen, or interior channel. While CVD's M(3) site-specific
drug delivery catheters are currently marketed internationally, they can only be
used in the United States to administer drugs specifically approved by the FDA
for administration by such catheters. The multiple lumens of the catheter may
also be used to deliver contrast media for angiographic viewing when advancing
the catheter along a totally occluded vessel. Traditional catheters must be
removed to inject contrast media into a total occlusion. Finally, the M(3)
technology can be utilized to provide perfusion of blood during an
interventional procedure. This perfusion capability allows the balloon to be
inflated for longer durations and reduces the number of inflations and
deflations required in certain procedures, and may increase the clinical
effectiveness of the treatment.
 
  Vascular Access Products
 
     The Company's vascular access products utilize patented technology to
provide rapid, accurate access to the body's vascular system for guidewire and
catheter entry. The principal current product, called the SmartNeedle, was
acquired from ACS and is based on Doppler ultrasound technology. A miniaturized
ultrasound chip is placed at the tip of a disposable ultrasonic probe which is
then placed inside a conventional vascular access needle. The probe is then
connected to a separate reusable monitor. Once placed in the body as a part of
the access needle, the Doppler chip emits an audible signal which enables the
physician to more accurately determine whether or not the needle resides in the
proper location within the intended arterial or venous lumen. Once positioned
properly, the probe is removed, leaving the conventional access needle in place
within the artery or vein. Since introduction, the SmartNeedle's primary use has
been in interventional cardiology and radiology procedures.
 
NEW PRODUCT DEVELOPMENT
 
     The Company focuses its research and development efforts on utilizing the
Company's proprietary processes and patented technologies to develop
cost-effective products that address existing and emerging clinical demands. The
Company's strategy is to refine its existing technologies and to enhance the
performance of its existing product offerings, including efforts to make its
Focus and M(3) products lower profile, more flexible and trackable, and operable
at a broader range of inflation pressures. In addition, the Company is
developing additional products utilizing combinations of its technologies that
may provide cardiologists greater therapeutic applicability in a single device.
The Company is also in the process of developing unique catheter designs
intended to provide enhanced delivery of therapeutic radial force and
pharmacological agents. The Company will be required to seek FDA approval for
any new product and it is

expected that some of these products will be subject to the PMA process. The
Company's current new product development efforts are summarized in the table

     The M(3) technology is being utilized in various experimental clinical
programs to administer the site-specific delivery of therapeutic agents
following angioplasty or stent delivery for the purpose of reducing or
eliminating restenosis. The Company is also using M(3) technology in its
MicroMembrane Radiation Therapy development program for restenosis prevention.
This program is evaluating CVD's M(3) technology to more accurately deliver
radioactive substances specifically to the treatment site.
 
TECHNOLOGY
 
     The Company has developed proprietary material manufacturing processes that
it has utilized to develop patented interventional catheters. Traditional
balloon extrusion technology does not enable the combination of compliant and
non-compliant materials, resulting in a catheter that can be inflated only to a
uniform diameter. The Company's Focus technology bonds a membrane between
compliant and non-compliant materials, resulting in a balloon with a large
center diameter and smaller, fixed diameters at each end. The center compliant
section of the Focus catheter enlarges predictably at a rate of 0.1mm per
atmosphere of pressure when inflation pressures exceed six atmospheres. The ends
of the balloon remain at their nominal diameters and do not expand with
increased pressure. The Focus capability enables cardiologists to deliver stents
or therapeutic radial force accurately to the treatment site, while minimizing
the force applied to adjacent tissue. Conventional uniform diameter catheters
may damage healthy vessel sections, as these sections receive as much radial
force as do the diseased sites. It is widely believed that vessel wall damage
may lead to acute reclosure of the vessel or restenosis.
 
     The Company's M(3) technology creates a membrane by applying mechanical and
radiation treatment to standard polymeric balloon material during the extrusion
process. Microporous holes are then drilled in the resulting material by
proprietary mechanical or laser drilling processes. CVD's M(3) technology
enables blood to flow through a coil lumen or inner shaft of the catheter,
allowing perfusion to the distal vessels (those beyond the treatment site)
during angioplasty or drug delivery. Prior to inflation, the balloon acts as a
shaft for the distal portion of the catheter. Once the balloon is inflated, the
cardiologist advances a coil into and through the inner lumen of the inflated
balloon. The coil supports the balloon during balloon angioplasty or drug
delivery and facilitates the perfusion of the distal vessels. The M(3)
technology enables the Company to combine balloon angioplasty and perfusion
capabilities on a single catheter in a profile comparable to standard balloon

angioplasty catheters without perfusion capability. The Company believes that
the M(3) technology also enables it to combine PTCA and perfusion capabilities
on a single catheter with a lower profile than any currently marketed catheter
with similar capabilities.
 
     The Company's IDI subsidiary, which was acquired in October 1996, utilizes
patented technology in the development of medical stents for the treatment of
patients with vascular disease caused by aneurysms or atherosclerosis. IDI is
developing a compact, self-expanding metallic stent with a micro-porous surface
for use as either a stent or a stent graft. By selecting metal foil of the
proper thickness and tensile strength, and heat-treating it in the proper shape,
the Company believes it will be able to form devices with low profiles, high
expansion ratios and excellent hoop strength, which are factors critical for
successful device placement. There can be no assurance that IDI will
successfully complete the development of any products or that any such products
will receive any required regulatory approvals.
 
MANUFACTURING
 
     With the exception of certain final assembly and sterilization procedures
for those products designed to be sold only outside the United States, and the
manufacture of those products which the Company has licensed to third parties,
all of the Company's products are produced in its facilities in Irvine,
California. The Company fabricates certain proprietary components, then
assembles, inspects, tests and packages all components into finished products.
By designing and assembling its catheter products, the Company believes it is
better able to control quality and costs, limit third-party access to its
proprietary technology, and manage manufacturing process enhancements and new
product introductions. In addition, the Company purchases many standard and
custom-built components from independent suppliers and subcontracts certain
processes from independent vendors. Most of these components and processes are
available from more than one vendor. However, certain manufacturing processes
are currently performed by single vendors. While the Company believes that there
are other vendors available to perform these processes, an interruption of
performance by any of these vendors could have a material adverse effect on the
Company's ability to manufacture its products until a new source of supply were
qualified and, as a result, could have an adverse effect on the Company's
business, financial condition and results of operations.
 
     The Company's success will depend in part upon its ability to manufacture
its products in compliance with ISO 9001, the FDA's GMP regulations, CDHS
licensing and other regulatory requirements, in sufficient quantities and on a
timely basis, while maintaining product quality and acceptable manufacturing
costs. The Company began manufacturing certain of its products at its facilities
in July 1995. The Company also introduced a significant number of new products
in 1996. Accordingly, the Company has very limited experience in manufacturing
its products. In addition, on July 15, 1996, the Company entered into co-
distribution agreements with Medtronic which granted Medtronic certain
non-exclusive rights to distribute the Company's FACT, CAT and ARC catheters.
Under the terms of these agreements, if the Company is unable to meet its
delivery obligations with respect to the purchased catheters, up to 60% of the
Company's manufacturing capacity will be devoted to manufacturing such catheters
for Medtronic. The Company has undergone and expects to continue to undergo
regular GMP inspections in connection with the manufacture of its products at
the Company's facilities. The Company's success will depend, among other things,
upon its ability to efficiently manage the simultaneous manufacture of different
products and to integrate the manufacture of new products with existing
products. There can be no assurance that the Company will not encounter
difficulties in scaling up production of new products, including problems
involving production yields, quality control and assurance, component supply and
shortages of qualified personnel. The Company's failure to successfully commence
the manufacturing of these new products, or to increase production volumes of
new and existing products in a timely manner, would materially adversely affect
the Company's business, financial condition and results of operations. Failure
to increase production volumes in a timely or cost-effective manner or to
maintain compliance with ISO 9001, GMP regulations, CDHS or other regulatory
requirements could have a material adverse effect on the Company's business,
financial condition and results of operations. See "Risk Factors -- Limited
Manufacturing Experience."

MARKETING AND SALES
 
     The Company's products are sold in the United States and international
markets, principally Europe and Japan. However, certain of the Company's
products are not available in each market due to regulatory and intellectual
property restrictions. The Company currently sells its products through a
combination of strategic partners, medical device distributors and eighteen
direct sales personnel. The Company is a party to three agreements for the U.S.
distribution of products incorporating its Focus and M(3) technologies. CVD also
has distribution agreements with 25 companies covering 41 countries outside the
United States and Japan. CVD currently distributes certain products in Japan
through an exclusive distribution agreement with Fukuda. Sales of the Company's
products through Fukuda accounted for 18% and 15% of the Company's total product
sales in 1995 and 1996, respectively. The Company recently informed Fukuda of
its decision to terminate the existing Fukuda agreement and does not expect that
any obligations will arise as a result of such termination. The Company expects
that Fukuda will continue to distribute its products at least through 1997. The
Company is currently negotiating with several distributors, including Fukuda,
regarding a new distribution agreement for the Japanese market. In addition,
sales to JJIS accounted for 12% of total product sales in 1995 and sales to
Medtronics accounted for 22% of total product sales in 1996. The Company intends
to expand its sales and marketing capability and to distribute selected new
products through strategic partnerships. See "Risk Factors -- Limited Marketing
and Sales Resources; Dependence Upon Strategic Relationships."
 
     In 1994, 1995 and 1996, total export sales were $970,000, $2,054,000 and
$3,514,000, respectively, or approximately 83%, 59% and 42% respectively, of
total product sales. In 1994, 1995 and 1996 sales to Europe accounted for
$255,000, $1,179,000 and $1,614,000, respectively; sales to Japan represented
$715,000, $744,000 and $1,240,000, respectively; and sales to Latin America
represented $0, $131,000 and $243,000, respectively. The Company expects to
continue to derive significant revenue from international sales and therefore a
significant portion of the Company's revenues will continue to be subject to the
risks associated with international sales, including economic or political
instability, shipping delays, changes in applicable regulatory policies,
inadequate protection of intellectual property, fluctuations in foreign currency
exchange rates and various trade restrictions, all of which could have a
significant impact on the Company's ability to deliver products on a competitive
and timely basis. Future imposition of, or significant increases in the level
of, customs duties, export quotas or other trade restrictions, could have an
adverse effect on the Company's business, financial condition and results of
operations. In foreign countries, the Company's products are subject to a wide
variety of governmental review and certification. The regulation of medical
devices, particularly in the European Community, continues to expand and there
can be no assurance that new laws or regulations will not have an adverse effect
on the Company. See Note 1 of Notes to Consolidated Financial Statements. See
"Risk Factors -- Dependence Upon International Sales."
 
POST-MARKETING CLINICAL STUDIES
 
     The Company has completed the clinical trials required for FDA approval of
those products which are marketed in the United States. In addition to those
trials, the Company is also sponsoring a controlled, randomized, multicenter
clinical study in the United States to continue to evaluate the clinical and
economic value of its core technologies. Data from this study is being
accumulated and analyzed to support the marketing of the Company's current
products.
 
     In a Comparative Performance and Pathological Study conducted by the
Division of Cardiology at the University of Texas Department of Medicine, the
Company's FACT catheter was compared with conventional PTCA catheters from other
leading manufacturers in an animal study. The investigators concluded that the
use of the FACT catheter resulted in reduced arterial damage without reduction
in catheter performance as determined by catheter preparation, trackability,
pushability, inflation/deflation and angiographic visualization.
 
     A second study is comparing the Focus PTCA catheter with conventional PTCA
catheters. The Focus Lesion Expansion Optimizes Results Study ("FLEXOR Study")
will evaluate the efficacy of Focus technology in improving clinical results
following angioplasty procedures. Success will be measured based on the ability
of Focus technology to improve the minimal lumen diameter ("MLD") of the
arterial opening, to
 
                                       30

                                    GG-30
<PAGE>   250
 
increase safety and to reduce the number of catheters necessary for PTCA
procedures. Results will be interpreted in light of any procedure-related
vascular complications, restenosis and occurrences of other major clinical
adverse cardiac events. MLD is a commonly-used measurement of the ability of a
therapeutic tool to open a blocked artery and reestablish required blood flow.
The FLEXOR Study was commenced in the fourth quarter of 1996. Completion is
expected in 1997.
 
     Certain of the Company's products which utilize Focus technology have
received FDA approval for PTCA and PTA indications. However, none of these
products has received FDA approval for use in stent delivery. An
investigator-controlled study is currently testing the Company's Focus
technology with respect to stent implantation. The Optimal Stent Implantation
Study ("OSTI-2 Study") is evaluating the ability of stent delivery with Focus
technology compared with conventional delivery techniques to reduce acute
outcomes and restenosis rates. The study is being conducted using two patient
subgroups of approximately 100 patients each divided according to vessel size.
In the first group, stent delivery is being evaluated in vessels greater than
three millimeters in diameter; in the second group stent delivery is being
evaluated in vessels less than three millimeters in diameter. Each subgroup
presents different clinical issues related to stent delivery and the OSTI-2
Study protocol is evaluating the efficacy of Focus technology in each subgroup.
The OSTI-2 Study began in February 1996 and is expected to be completed in 1997.
 
     The Company also intends to sponsor additional studies from time to time to
assess the value of, and to expand clinical indications of, its existing and new
technologies. The Company is planning a clinical study to expand the clinical
uses of its Focus technology catheters to include balloon dilatation of
previously deployed stents in order to properly implant the stent in the
arterial wall of small coronary vessels. This study will include approximately
100 patients and is expected to be completed in 1997.
 
STRATEGIC RELATIONSHIPS
 
     The Company evaluates on an ongoing basis potential strategic relationships
with corporate and other partners where such relationships may complement and
expand CVD's research, development, sales and marketing capabilities. The
Company is currently a party to four such agreements, described below.
 
     Advanced CardioVascular Systems, Inc.  In January 1995, the Company entered
into a license agreement with ACS. The parties subsequently confirmed their
understanding with respect to certain matters in a second agreement dated March
4, 1996 (collectively, the "ACS Agreements"). Under the ACS Agreements, the
Company acquired certain rights to ACS' SmartNeedle technology, subject to the
payment of certain royalties. ACS was granted the option to acquire the
exclusive worldwide rights to certain CVD perfusion technology, which ACS
exercised on February 14, 1996. As a result, ACS has an exclusive worldwide
right to develop, manufacture and market the Company's MAC I product line. In
exchange for this technology, ACS is obligated to make milestone and minimum
annual royalty payments to CVD, and also has certain obligations to develop and
market the technology. In addition, in the event that CVD develops a product
which combines coronary balloon angioplasty, perfusion and drug delivery
technology on the same catheter, ACS will have certain rights to license such
product. The ACS Agreements may be terminated upon 60 days notice in the event
of a breach by the other party, subject to the breaching party's right to cure,
or by ACS upon 30 days notice without cause.
 
     SCIMED Life Systems, Inc.  The Company has entered into a Stock Purchase
and Technology License Agreement, dated September 10, 1994, with SCIMED (the
"SCIMED Agreement"). Pursuant to the SCIMED Agreement, SCIMED purchased a 19%
equity position in the Company. SCIMED was also granted an exclusive worldwide
license to certain combined site-specific drug delivery and coronary angioplasty
technology, including the Company's Transport products, for use in the
cardiovascular field in exchange for license and royalty fees. The SCIMED
Agreement also requires CVD to provide certain technical assistance and to
perform additional research and development relating to the licensed technology
in exchange for fees and reimbursement of expenses. In the event that CVD's
SCIMED-funded research and development efforts result in improvements to the
licensed technology, SCIMED will have an exclusive worldwide license to the
technology in the cardiovascular field and a non-exclusive license outside the
cardiovascular field, both of which are subject to the payment of royalties. The
SCIMED Agreement may be
 
                                       31

                                    GG-31
<PAGE>   251
 
terminated in the event of breach on 90 days notice by the non-breaching party
(or on 30 days notice in certain limited circumstances) or by SCIMED upon 180
days notice.
 
     Fukuda Denshi Co., Ltd.  The Company entered into a Distribution Agreement,
dated May 28, 1993, with Fukuda Denshi Co., Ltd. (the "Fukuda Agreement"),
whereby Fukuda served as CVD's exclusive distributor for certain of the
Company's products in Japan. In exchange for this exclusive distributorship,
Fukuda paid a fee to CVD in addition to payments owing upon the purchase of the
products. Fukuda also agreed to undertake all necessary clinical trials to
obtain approval from Japanese regulatory authorities for the sale of the
products in Japan. Fukuda's purchases under the Fukuda Agreement are subject to
certain minimum requirements. The initial term of the Fukuda Agreement expires
on May 31, 1998, subject to a five-year extension. The Fukuda Agreement may also
be terminated in the event of breach upon 90 days notice by the non-breaching
party. In July 1995 and May 1996, the distribution agreement with Fukuda was
amended to grant Fukuda exclusive distribution rights to additional CVD
products. Under these amendments, the Company received $750,000 which converted
into the right to receive 62,500 shares of Common Stock upon the consummation of
the Company's initial public offering on June 19, 1996. Fukuda received these
shares on November 29, 1996. The Company recently informed Fukuda of its
decision to terminate the existing Fukuda Agreement and does not expect that any
obligations will arise as a result of such termination. The Company expects that
Fukuda will continue to distribute its products at least through 1997. The
Company is currently negotiating with several distributors, including Fukuda,
regarding a new distribution agreement for the Japanese market.
 
     EndoSonics Corporation.  The Company has entered into a license agreement
with EndoSonics, dated December 22, 1995 (the "EndoSonics Agreement"), pursuant
to which CVD granted EndoSonics the non-exclusive, royalty-free right to CVD's
Focus technology for the development and sale of a combined Focus/Ultrasound
product. In exchange, CVD received the non-exclusive, royalty-free right to
submit PMA supplement applications utilizing an EndoSonics PMA as a reference
and to manufacture and distribute CVD products as a supplement to the EndoSonics
PMA. The EndoSonics Agreement may be terminated in the event of breach upon 60
days notice by the nonbreaching party, subject to the breaching party's right to
cure. In the event of termination, the Company would be prohibited from
submitting new PMA supplements referencing the EndoSonics PMA and would be
required to seek independent FDA approval for such products, which would have a
material adverse effect on the Company's business, financial condition and
results of operations. In addition, in March of 1996, EndoSonics purchased
400,000 shares of CVD's Series B Preferred Stock for a purchase price of
$8,000,000, that converted into 800,000 shares of Common Stock upon the
consummation of the Company's initial public offering on June 19, 1996. See
"Certain Transactions -- Relationship with EndoSonics Corporation."
 
     Medtronic, Inc.  On July 15, 1996, the Company entered into co-distribution
agreements with Medtronic, providing for the co-distribution of the Company's
FACT, CAT and ARC balloon angioplasty catheters. Under the terms of these
agreements, Medtronic will purchase a minimum number of angioplasty catheters
manufactured by the Company for distribution worldwide for a period of up to
three years. If the Company is unable to meet its delivery obligations regarding
the purchased catheters, up to 60% of the Company's manufacturing capacity will
be devoted to manufacturing such catheters for Medtronic. Specific products to
be distributed by Medtronic will differ in individual country markets. The
initial term of the Medtronic agreements is for a period of three years from the
date of first delivery of a product. The agreements may be terminated in the
event of breach upon notice by the nonbreaching party, subject to the breaching
party's right to cure.
 
PATENTS AND PROPRIETARY INFORMATION
 
     The Company's policy is to protect its proprietary position by, among other
methods, filing U.S. and foreign patent applications to protect technology,
inventions and improvements that are important to the development of its
business. The Company has eleven issued U.S. patents covering certain aspects of
its catheter technology and licenses, and additional patents relating to the
vascular access and IDI stent technology. No assurance can be given that any
issued patents will provide competitive advantages for the Company's products,
or that they will not be challenged or circumvented by competitors.

                                    GG-32
<PAGE>   252
 
     The interventional cardiovascular market in general and the balloon
angioplasty catheter market (including the type of catheters offered by CVD) in
particular have been characterized by substantial litigation regarding patent
and other intellectual property rights. There can be no assurance that the
Company's products do not infringe such patents or rights. During 1996, the
Company received a notice of potential trademark infringement regarding the
Company's use of the term "focal" in connection with the Company's balloon
angioplasty catheter. CVD entered into an agreement which prohibits the Company
from using this term. The Company has since ceased any use thereof. In the event
that any such third-parties assert claims against the Company for patent
infringement and such patents are upheld as valid and enforceable, the Company
could be prevented from utilizing the subject matter claimed in such patents, or
would be required to obtain licenses from the owners of any such patents or
redesign its products or processes to avoid infringement. There can be no
assurance that such licenses would be available or, if available, would be so on
terms acceptable to the Company or that the Company would be successful in any
attempt to redesign its products or processes to avoid infringement. In
addition, foreign intellectual property laws may not provide protection
commensurate with that provided by U.S. intellectual property laws, and there
can be no assurance that foreign intellectual property laws will adequately
protect the Company's intellectual property rights abroad. The Company also
relies on trade secrets and proprietary technology and enters into
confidentiality and non-disclosure agreements with its employees, consultants
and advisors. There can be no assurance that the confidentiality of such trade
secrets or proprietary information will be maintained by employees, consultants,
advisors or others, or that the Company's trade secrets or proprietary
technology will not otherwise become known or be independently developed by
competitors in such a manner that the Company has no practical recourse.
Litigation may be necessary to defend against claims of infringement or
invalidity, to enforce patents issued to the Company or to protect trade
secrets. There can be no assurance that any such litigation would be successful.
Any litigation could result in substantial costs to, and diversion of resources
by, the Company and its officers, which would have a material adverse effect on
its business, financial condition and results of operations. See "Risk
Factors -- Reliance on Patents and Proprietary Technology; Risk of Patent
Infringement."
 
COMPETITION
 
     The Company believes that the primary competitive factors in the market for
interventional cardiology devices are: clinical effectiveness, product safety,
catheter size, flexibility and trackability, ease of use, reliability, price and
availability of third party reimbursement. In addition, a company's distribution
capability and the time in which products can be developed and receive
regulatory approval are important competitive factors. The Company believes it
competes favorably with respect to the foregoing factors. The Company also
believes that its competitive position is dependent upon its ability to continue
to develop innovative new catheter technologies and obtain rapid regulatory
approval.
 
     Competition in the market for devices used in the treatment of
cardiovascular and peripheral vascular disease is intense, and is expected to
increase. The interventional cardiology market is characterized by rapid
technological innovation and change, and the Company's products could be
rendered obsolete as a result of future innovations. The Company's catheters and
other products under development compete or will compete with catheters marketed
by a number of manufacturers, including ACS, SCIMED, JJIS and Cordis
Corporation, subsidiaries of Johnson & Johnson, Medtronic, Inc., C.R. Bard, Inc.
and Schneider USA, a subsidiary of Pfizer, Inc. Such companies have
significantly greater financial, management and other resources, established
market positions, and significantly larger sales and marketing organizations
than does the Company. The Company also faces competition from manufacturers of
other catheter-based atherectomy devices, vascular stents and pharmaceutical
products intended to treat vascular disease. In addition, the Company believes
that many of the purchasers and potential purchasers of the Company's products
prefer to purchase catheter products from a single source. Accordingly, many of
the Company's competitors, because of their size and range of product offerings,
have a competitive advantage over the Company. There can be no assurance that
the Company's competitors will not succeed in developing or marketing
technologies and products that are more clinically effective or cost effective
than any that are being marketed or developed by the Company, or that such
competitors will not succeed in obtaining regulatory approval for introducing or
commercializing any such products prior to the Company. See "Risk
Factors -- Significant Competition."

THIRD-PARTY REIMBURSEMENT
 
     In the United States, the Company's products are purchased primarily by
medical institutions, which then bill various third-party payors, such as
Medicare, Medicaid, and other government programs and private insurance plans,
for the health care services provided to patients. Government agencies, private
insurers and other payors determine whether to provide coverage for a particular
procedure and reimburse hospitals for medical treatment at a fixed rate based on
the diagnosis-related group ("DRG") established by the U.S. HCFA. The fixed rate
of reimbursement is based on the procedure performed, and is unrelated to the
specific devices used in that procedure. If a procedure is not covered by a DRG,
payors may deny reimbursement. In addition, some payors may deny reimbursement
if they determine that the device used in a treatment was unnecessary,
inappropriate or not cost-effective, experimental or used for a non-approved
indication. Reimbursement of interventional procedures utilizing the Company's
products is currently covered under a DRG. There can be no assurance that
reimbursement for such procedures will continue to be available, or that future
reimbursement policies of payors will not adversely affect the Company's ability
to sell its products on a profitable basis. Failure by hospitals and other users
of the Company's products to obtain reimbursement from third-party payors, or
changes in government and private third-party payors' policies toward
reimbursement for procedures employing the Company's products, would have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Risk Factors -- Limitations on Third-Party
Reimbursement."
 
GOVERNMENT REGULATION
 
     The manufacturing and marketing of the Company's products are subject to
extensive and rigorous government regulation in the United States and in other
countries. The Company believes that its success will be significantly dependent
upon commercial sales of improved versions of its catheter products. The Company
will not be able to market these new products in the United States unless and
until the Company obtains approval or clearance from the FDA. Foreign and
domestic regulatory approvals, if granted, may include significant limitations
on the indicated uses for which a product may be marketed.
 
     If a medical device manufacturer can establish that a newly developed
device is "substantially equivalent" to a legally marketed Class I or Class II
device, or to a Class III device that the FDA has not called for a PMA, the
manufacturer may seek clearance from the FDA to market the device by filing a
premarket notification with the FDA under Section 510(k) of the Federal Food,
Drug, and Cosmetic Act. All of the 510(k) clearances received for the Company's
catheters were based on substantial equivalence to legally marketed devices.
There can be no assurance that 510(k) clearance for any future product or
significant modification of an existing product will be granted or that the
process will not be unduly lengthy. In addition, if the FDA has concerns about
the safety or effectiveness of any of the Company's products, it could act to
withdraw approval or clearances of those products or request that the Company
present additional data. Any such actions would have a material adverse effect
on the Company's business, financial condition and results of operations.
 
     If substantial equivalence cannot be established, or if the FDA determines
that the device or the particular application for the device requires a more
rigorous review to assure safety and effectiveness, the FDA will require that
the manufacturer submit a PMA application that must be reviewed and approved by
the FDA prior to sales and marketing of the device in the United States. The PMA
process is significantly more complex, expensive and time consuming than the
510(k) clearance process and always requires the submission of clinical data. It
is expected that certain of the Company's products under development will be
subject to this PMA process. The Company currently has a non-exclusive,
royalty-free right to submit PMA supplement applications utilizing an EndoSonics
PMA as a reference and to manufacture and distribute CVD products as a
supplement to the EndoSonics PMA. This agreement may be terminated in the event
of breach upon 60 days notice by the non-breaching party, subject to the
breaching party's right to cure. In the event of termination, the Company would
be prohibited from submitting new PMA supplements referencing the EndoSonics PMA
and would be required to seek independent FDA approval for any such products,
which would have a material adverse effect on the Company's business, financial
condition and results of operations.

     The Company is also required to register as a medical device manufacturer
with the FDA and maintain a license with certain state agencies, such as the
CDHS. As such, the Company is inspected on a routine basis by both the FDA and
the CDHS for compliance with GMP regulations. These regulations require that the
Company manufacture its products and maintain related documentation in a
prescribed manner with respect to manufacturing, testing and control activities.
The Company has also undergone and expects to continue to undergo regular GMP
inspections in connection with the manufacture of its products at the Company's
facilities. Further, the Company is required to comply with various FDA
requirements for labeling. The Medical Device Reporting laws and regulations
require that the Company provide information to the FDA on deaths or serious
injuries alleged to have been associated with the use of its devices, as well as
product malfunctions that would likely cause or contribute to death or serious
injury if the malfunction were to recur. In addition, the FDA prohibits an
approved device from being marketed for unapproved applications. CVD has
received FDA approval to market the FACT and ARC catheters, which utilize the
FOCUS technology, for coronary balloon angioplasty. These catheters are marketed
outside the United States for use in stent deployment. However, without specific
FDA approval for stent deployment, these catheters may not be marketed by the
Company in the United States for such use.
 
     Failure to comply with applicable regulatory requirements can, among other
consequences, result in fines, injunctions, civil penalties, suspensions or loss
of regulatory approvals, product recalls, seizure of products, operating
restrictions and criminal prosecution. In addition, government regulations may
be established in the future that could prevent or delay regulatory clearance or
approval of the Company's products. Delays in receipt of clearances or
approvals, failure to receive clearances or approvals or the loss of previously
received clearances or approvals would have a material adverse effect on the
Company's business, financial condition and results of operations.
 
     The Company is also subject to other federal, state and local laws,
regulations and recommendations relating to safe working conditions, laboratory
and manufacturing practices. The extent of government regulation that might
result from any future legislation or administrative action cannot be accurately
predicted. Failure to comply with regulatory requirements could have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
     International sales of the Company's products are subject to the
registration requirements of each country. The regulatory review process varies
from country to country and may in some cases require the submission of clinical
data. The Company typically relies on its distributors in such foreign countries
to obtain the requisite regulatory approvals. There can be no assurance,
however, that such approvals will be obtained on a timely basis or at all. In
addition, the FDA must approve the export to certain countries of devices that
require a PMA but are not yet approved domestically. The European Union has
promulgated rules which require that medical products receive by mid-1998 the
right to affix the CE mark, an international symbol of adherence to quality
assurance standards and compliance with applicable European medical device
directives. Failure to receive the right to affix the CE mark will prevent the
Company from selling its products in member countries of the European Union,
which would have a material adverse effect on the Company's business, financial
condition and results of operations.
 
PRODUCT LIABILITY
 
     The Company faces the risk of financial exposure to product liability
claims. The Company's products are often used in situations in which 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. The Company is currently covered under a product
liability insurance policy with coverage limits of $2.0 million per occurrence
and $2.0 million per year in the aggregate. There can be no assurance that the
Company's product liability insurance is adequate or that such insurance
coverage will remain available at acceptable costs. There can be no assurance
that the Company will not incur significant product liability claims in the
future. A successful claim brought against the Company in excess of its
insurance coverage could have a material adverse effect on the Company's
business, financial condition and results of operations. Additionally, adverse
product liability actions could negatively affect the reputation and sales of
the

Company's products and the Company's ability to obtain and maintain regulatory
approval for its products and substantially divert the time and effort of
management away from the Company's operations.
 
EMPLOYEES
 
     As of April 15, 1997, the Company had 161 employees, including 94 in
manufacturing, 32 in research, development and regulatory affairs, 28 in sales
and marketing and 7 in administration. The Company believes that the success of
its business will depend, in part, on its ability to attract and retain
qualified personnel. The Company believes it has good relations with its
employees.
 
PROPERTIES
 
     Currently, the Company leases facilities aggregating approximately 33,000
square feet in Irvine, California under lease agreements which expire beginning
in 1998. The Company believes that its facilities are adequate to meet its
requirements through mid-1998.

(1) The option listed in the table was granted under the Company's 1996 Stock
    Option/Stock Issuance Plan. The option was granted on November 4, 1996, and
    has a maximum term of ten years measured from the grant date, subject to
    earlier termination upon the optionee's termination of service with the
    Company. Twenty-five percent (25%) of the options are exercisable upon the
    optionee's completion of one year of service measured from November 4, 1996,
    and as to the balance of the option shares in a series of successive equal
    monthly installments upon the optionee's completion of each additional month
    of service over the next 36 months thereafter.
 
(2) Based upon options granted for an aggregate of 319,000 shares to employees
    in 1996, including the Named Officers.
 
(3) The exercise price may be paid in cash, in shares of the Company's 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. The
    Company 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. The Compensation Committee of the
    Board of Directors, as the Plan Administrator of the Company's 1996 Stock
    Option/Stock Issuance Plan, has the discretionary authority to reprice the
    options through the cancellation of those options and the grant of
    replacement options with an exercise price based on the fair market value of
    the option shares on the grant date.
 
(4) 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 the
    Company's securities that the actual stock price appreciation over the
    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.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     The Compensation Committee of the Company's Board was formed in May 1996,
and the members of the Compensation Committee are Messrs. Davis and Dann.
Neither of these individuals was at any time during the fiscal year ended
December 31, 1996, or at any other time, an officer or employee of the Company.
No member of the Compensation Committee of the Company serves as a member of the
board of directors or compensation committee of any entity that has one or more
executive officers serving as a member of the Company's Board of Directors or
Compensation Committee.
 
1996 STOCK OPTION/STOCK ISSUANCE PLAN
 
     The Company's 1996 Stock Option/Stock Issuance Plan (the "1996 Plan")
serves as the successor equity incentive program to the Company's 1995 Stock
Option Plan (the "Predecessor Plan"). The 1996 Plan was adopted by the Board of
Directors and approved by the stockholders on May 1, 1996, (the "Effective
Date"). On April 8, 1997 the Board of Directors amended the 1996 Plan to (i)
increase the number of shares authorized for issuance thereunder, (ii) render
non-employee Board members eligible to participate in the Discretionary Option
Grant and Stock Issuance Programs and (iii) make certain other changes to take
advantage of amendments made in 1996 to Rule 16b-3 of the Securities and
Exchange Commission which exempts certain officer and director transactions
under the 1996 Plan from the short-swing profit liability provisions of the
Federal securities laws. The amendments to the 1996 Plan were approved by the
Company's stockholders at the 1997 Annual Meeting. Under the 1996 Plan,
1,900,000 shares of Common Stock have been authorized for issuance. This share
reserve is comprised of (i) the 1,200,000 shares which remained available for
issuance under the Predecessor Plan as of the Effective Date, including the
shares subject to outstanding options thereunder and (ii) the 700,000-share
increase adopted by the Board of Directors in April 1997 and approved by the
stockholders at the 1997 Annual Meeting. The outstanding options under the
Predecessor Plan were incorporated into the 1996 Plan on the Effective Date, and
no further option grants will be made under the Predecessor Plan after such
date. The incorporated options will continue to be governed by their original
terms, unless the Plan Administrator elects to extend one or more features of
the 1996 Plan to those options. However, except as otherwise noted below, the
outstanding options under the Predecessor Plan contain substantially the same
terms and conditions specified below for the Discretionary Option Grant Program
in effect under the 1996 Plan. In no event may any one participant in the 1996
Plan receive option grants or direct stock issuances for more than 800,000
shares in the aggregate over the term of the Plan.
 
     The 1996 Plan is divided into three separate components: (i) the
Discretionary Option Grant Program under which eligible individuals may, at the
discretion of the Plan Administrator, be granted options to purchase shares of
Common Stock at an exercise price not less than 85% of their fair market value
on the grant date, (ii) the Stock Issuance Program under which such individuals
may, in the Plan Administrator's discretion, be issued shares of Common Stock
directly, through the purchase of such shares at a price not less than 85% of
their fair market value at the time of issuance or as a bonus tied to the
performance of services and (iii) 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 their fair market value on the grant date.
 
     The Discretionary Option Grant and Stock Issuance Programs are administered
by the Compensation Committee. The Compensation Committee as Plan Administrator
has complete discretion to determine which eligible individuals are to receive
option grants or stock issuances, the time or times when such option grants or
stock issuances are to be made, the number of shares subject to each such grant
or issuance, the status of any granted option as either an incentive stock
option or a non-statutory stock option under the Federal tax laws, the vesting
schedule to be in effect for the option grant or stock issuance and the maximum
term for which any granted option is to remain outstanding.
 
     Under the 1996 Plan, upon an acquisition of the Company by merger or asset
sale or a hostile take-over of the Company, each outstanding option and unvested
stock issuance will be subject to accelerated vesting under certain
circumstances. The options granted under the Predecessor Plan will be assumed or
replaced in a merger
 
                                       41

                                    GG-41
<PAGE>   261
 
or asset sale but do not include any acceleration provisions in connection with
such a merger or asset sale or upon a hostile take-over, although such options
may be accelerated at the discretion of the Plan Administrator.
 
     Stock appreciation rights are authorized for issuance under the
Discretionary Option Grant Program which provide the holders with the election
to surrender their outstanding options for an appreciation distribution from the
Company equal to the excess of (i) the fair market value of the vested shares of
Common Stock subject to the surrendered option over (ii) the aggregate exercise
price payable for such shares. Such appreciation distribution may be made in
cash or in shares of Common Stock. No stock appreciation rights exist with
respect to options currently outstanding under the Predecessor Plan.
 
                                       42

                                    GG-42
<PAGE>   262
 
     The Plan Administrator has the authority to effect the cancellation of
outstanding options under the Discretionary Option Grant Program (including
options incorporated from the Predecessor Plan) in return for the grant of new
options for the same or different number of option shares with an exercise price
per share based upon the fair market value of the Common Stock on the new grant
date.
 
     Under the Automatic Option Grant Program, each non-employee Board member
serving on June 19, 1996, the date the Underwriting Agreement for the initial
public offering was executed, received an option grant on such date for 5,000
shares of Common Stock. Each individual who first becomes a non-employee Board
member thereafter will receive a 5,000-share option grant on the date such
individual joins the Board provided such individual has not been in the prior
employ of the Company. In addition, at each Annual Stockholders Meeting, each
individual who is to continue to serve as a non-employee Board after the meeting
will receive an additional option grant to purchase 5,000 shares of Common Stock
whether or not such individual has been in the prior employ of the Company.
 
     Each automatic grant will have a term of 10 years, subject to earlier
termination following the optionee's cessation of Board service. Each automatic
option will be immediately exercisable; however, any shares purchased upon
exercise of the option will be subject to repurchase should the optionee's
service as a non-employee Board member cease prior to vesting in the shares. The
initial 5,000-share grant will vest in four equal and successive annual
installments over the optionee's period of Board service. Each additional annual
5,000-share grant will vest upon the optionee's completion of one year of Board
service measured from the grant date. However, each outstanding option will
immediately vest upon (i) certain changes in the ownership or control of the
Company or (ii) the death or disability of the optionee while serving as a Board
member.
 
     The Board may amend or modify the 1996 Plan at any time. The 1996 Plan will
terminate on April 30, 2006, unless sooner terminated by the Board.
 
NON-EMPLOYEE BOARD MEMBER REMUNERATION
 
     The Company has adopted a policy under which each non-employee board member
receives a cash payment in the amount of $1,500 per quarter.
 
EMPLOYEE STOCK PURCHASE PLAN
 
     The Company's Employee Stock Purchase Plan (the "Purchase Plan") was
adopted by the Board of Directors and approved by the stockholders on May 1,
1996. 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 a reserve of 200,000 shares of Common Stock has been established for
this purpose.
 
     The Purchase Plan will be implemented in a series of successive offering
periods, each with a maximum duration of twenty-four months. The initial
offering period began on June 19, 1996, the day the Underwriting Agreement for
the initial public offering was executed, based on the initial public offering
price and will end on the last business day in July 1998. Each offering period
will be comprised of successive purchase intervals, each having a duration of
six months. However, the first purchase interval under the initial offering
period began on June 19, 1996 and ended in January 31, 1997. Shares of Common
Stock will be purchased for each participant at the end of each purchase
interval during the offering period. If the fair market value of the Common
Stock on any purchase date in the offering period is less than the fair market
value of the Common Stock at the start of the offering period, then that
offering period will terminate and a new offering period will automatically
commence on the next business day following that purchase date.
 
     Payroll deductions may not exceed 10% of base salary for each purchase
interval. The purchase price per share will be 85% of the lower of (i) the fair
market value of the Common Stock on the participant's entry date into the
offering period or (ii) the fair market value on the semi-annual purchase date.
In no event may any participant purchase more than 950 shares of Common Stock on
any purchase date.
 
     The Board may terminate the Purchase Plan at any time. The Purchase Plan
will terminate in all events on the last business day in July 2006.

LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
     The Company's Certificate of Incorporation limits the liability of
directors to the maximum extent permitted by Delaware law. Delaware law provides
that a director of a corporation will not be personally liable for monetary
damages for breach of such individual's fiduciary duties as a director except
for liability (i) for any breach of such director's duty of loyalty to the
corporation, (ii) for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law, (iii) for unlawful
payments of dividends or unlawful stock repurchases or redemptions as provided
in Section 174 of the Delaware General Corporation Law, or (iv) for any
transaction from which a director derives an improper personal benefit.
 
     The Company's Bylaws provide that the Company will indemnify its directors
and may indemnify its officers, employees and other agents to the fullest extent
permitted by law. The Company believes that indemnification under its Bylaws
covers at least negligence and gross negligence on the part of an indemnified
party and permits the Company to advance expenses incurred by an indemnified
party in connection with the defense of any action or proceeding arising out of
such party's status or service as a director, officer, employee or other agent
of the Company upon an undertaking by such party to repay such advances if it is
ultimately determined that such party is not entitled to indemnification.
 
     The Company has entered into separate indemnification agreements with each
of its directors. These agreements require the Company, among other things, to
indemnify such director against expenses (including attorneys' fees), judgments,
fines and settlements (collectively, "Liabilities") paid by such individual in
connection with any action, suit or proceeding arising out of such individual's
status or service as a director of the Company (other than Liabilities arising
from willful misconduct or conduct that is knowingly fraudulent or deliberately
dishonest) and to advance expenses incurred by such individual in connection
with any proceeding against such individual with respect to which such
individual may be entitled to indemnification by the Company.
 
     The Company believes that its Certificate of Incorporation and Bylaw
provisions and indemnification agreements are necessary to attract and retain
qualified persons as directors and officers. At present the Company is not aware
of any pending litigation or proceeding involving any director, officer,
employee or agent of the Company where indemnification will be required or
permitted. The Company is not aware of any threatened litigation or proceeding
that might result in a claim for such indemnification.
 
EMPLOYMENT CONTRACTS AND CHANGE OF CONTROL ARRANGEMENTS
 
     The Company does not presently have any employment contracts in effect with
any of its executive officers.
 
     The Compensation Committee as Plan Administrator of the 1996 Plan has the
authority to provide for the accelerated vesting of the shares of Common Stock
subject to outstanding options held by the Chief Executive Officer and any other
executive officers or the shares of Common Stock subject to direct issuances
held by such individual, in connection with certain changes in control of the
Company or the subsequent termination of the officer's employment following the
change in control event.
 
                              CERTAIN TRANSACTIONS
 
RELATIONSHIP WITH ENDOSONICS CORPORATION
 
     On June 15, 1992, EndoSonics acquired a 40% interest in CVD in exchange for
$568,000 in cash. Upon completion of this investment, EndoSonics' President and
Chief Executive Officer owned a 19% equity interest in CVD and served as
Chairman of the Board. Pursuant to an Agreement and Plan of Reorganization
between EndoSonics and CVD signed on June 9, 1993, EndoSonics acquired all of
the outstanding capital stock of CVD in exchange for $335,000 in cash and
250,000 shares of EndoSonics' Common Stock with an aggregate market value of
$1,563,000. Pursuant to the terms of the Agreement and Plan of Reorganization,
in June 1995, EndoSonics became obligated to issue 50,000 shares of its Common
Stock with an aggregate market value of $488,000, to the former shareholders of
CVD because the market price of EndoSonics' stock
 
                                       44

                                    GG-44
<PAGE>   264
 
did not exceed a specified price for a specified period during the two-year
period following the acquisition. On March 29, 1996, EndoSonics acquired 400,000
shares of Series B Preferred Stock for a purchase price of $8,000,000, which
converted into 800,000 shares of Common Stock upon the consummation of the
initial public offering.
 
     During 1994 and 1995, EndoSonics manufactured certain of the Company's
catheter products. Total purchases from EndoSonics during 1994 and 1995 amounted
to $0.8 million and $0.2 million, respectively. In addition, during 1994
EndoSonics performed certain billing and collection services for the Company in
return for a fee per invoice which amounted to $10,000. In addition, since
August 1993, certain of the Company's corporate expenses, including Mr. Henson's
salary, were paid by EndoSonics and accounting, cash management and other
administrative services were performed by EndoSonics. Pursuant to this
arrangement, the Company paid EndoSonics an aggregate of $227,000, $340,000 and
$156,000 for 1994, 1995 and 1996, respectively. In addition, EndoSonics paid Mr.
Henson's bonus for 1995. See "Management -- Executive Compensation."
 
     The Company entered into a license agreement with EndoSonics, dated
December 22, 1995 (the "EndoSonics Agreement"), pursuant to which CVD granted
EndoSonics the non-exclusive, royalty-free right to CVD's Focus technology for
the development and sale of a combined Focus/Ultrasound product. In exchange,
CVD received the non-exclusive, royalty-free right to submit PMA supplement
applications utilizing an EndoSonics PMA as a reference and to manufacture and
distribute CVD products as a supplement to the EndoSonics PMA. The EndoSonics
Agreement may be terminated in the event of breach upon 60 days notice by the
non-breaching party, subject to the breaching party's right to cure.
 
     CVD and EndoSonics have entered into certain agreements for the purpose of
defining the ongoing relationship between the two companies. EndoSonics owned
approximately 84% of the outstanding voting capital stock of CVD prior to the
initial public offering and currently owns approximately 44% of CVD's Common
Stock. Accordingly, these agreements are not the result of arm's-length
negotiations between independent parties.
 
     CVD and EndoSonics have entered into a Tax Allocation Agreement that
provides, among other things, for (i) the allocation of tax liabilities and
adjustments thereto as between the business of the Company and other businesses
conducted by EndoSonics and its affiliates related to periods in which the
Company is includable in consolidated federal income tax returns filed by
EndoSonics, (ii) the allocation of responsibility for filing tax returns and
(iii) the conduct of and responsibility for taxes owed in connection with tax
audits and various related matters, as described below.
 
     EndoSonics has agreed to indemnify CVD for any federal and state income tax
liability arising out of any audit with respect to periods ending prior to the
closing of the Company's initial public offering and for which CVD was included
in EndoSonics' consolidated federal income tax return or a state unitary or
combined return. In addition, with respect to periods for which CVD is included
in EndoSonics' federal consolidated or state unitary tax return, EndoSonics
shall control the filing of such returns and the conduct of any audits thereof.
With respect to periods following the closing of the initial public offering,
the Company will file its own federal income tax return and will not be included
in EndoSonics' federal return. The Company will initially be included in certain
unitary or combined returns for state tax purposes. To the extent this occurs,
this agreement generally treats the Company as a separate taxpayer and charges
the Company with its separate tax return liability.
 
     EndoSonics and CVD have entered into a Stockholder Agreement providing that
all transactions between the Company and EndoSonics or any affiliate of
EndoSonics must be approved by a special committee of CVD's Board of Directors
comprised of two directors who are not officers, directors, employees or
affiliates of EndoSonics. The members of this committee are Mitchell Dann and
Gerard von Hoffmann. No transactions between the Company and EndoSonics are
currently contemplated. During the effective term of the Agreement, EndoSonics
may not vote to eliminate from the Company's Certificate of Incorporation
provisions requiring cumulative voting for the election of directors. The
provisions of the Agreement became effective upon the consummation of the
initial public offering and terminate on the earlier of seven years from the
date of the Agreement or on the date EndoSonics beneficially owns less than 25%
of CVD's Common Stock.

<PAGE>   265
 
     On January 27, 1997, EndoSonics announced that the EndoSonics Board of
Directors had approved a dividend distribution of one CVD share for every 25
EndoSonics shares. The distribution is expected to take place in the second half
of 1997 to EndoSonics Stockholders then of record. The exact record date and
date of distribution have not yet been determined.
 
     EndoSonics and CVD have entered into a Registration Rights Agreement in
connection with the acquisition of Cardiometrics by EndoSonics which provides
that CVD will use its best efforts to register under the Securities Act, the CVD
shares held by EndoSonics for distribution to Cardiometrics' stockholders in the
Merger. EndoSonics has agreed to bear all expenses incurred in connection with
such registration.
 
OTHER TRANSACTIONS
 
     On September 10, 1994, the Company entered into a Stock Purchase and
Technology License Agreement with SCIMED (the "SCIMED Agreement"). Pursuant to
the SCIMED Agreement, SCIMED purchased a 19% equity position in the Company for
a purchase price of $2,500,000. SCIMED was also granted an exclusive worldwide
license to certain site-specific drug delivery/PTCA technology for use in the
cardiovascular field in exchange for license and royalty fees. The SCIMED
Agreement also requires CVD to provide certain technical assistance and to
perform additional research and development relating to the licensed technology
in exchange for fees and reimbursement of expenses, respectively. In the event
that CVD's SCIMED-funded research and development efforts result in improvements
to the licensed technology, SCIMED will have an exclusive worldwide license to
the technology in the cardiovascular field and a non-exclusive license outside
the cardiovascular field, both of which are subject to the payment of royalties.
The SCIMED Agreement may be terminated in the event of breach on 90 days notice
by the non-breaching party (or on 30 days notice in certain limited
circumstances) or by SCIMED upon 180 days notice.
 
     In connection with the adoption of the Predecessor Plan, the Company issued
a warrant to SCIMED in June 1995 to purchase 40,000 shares of Series A Preferred
Stock at an exercise price of $6.58 per share in exchange for a waiver of
SCIMED's anti-dilution rights under the SCIMED Agreement. The Company
subsequently issued a warrant for an additional 20,000 shares of Series A
Preferred at $6.58 per share in connection with an increase in the number of
shares reserved for issuance under the Predecessor Plan. Following the
consummation of the initial public offering, these warrants became exercisable
for 80,000 shares of Common Stock and 40,000 shares of Common Stock,
respectively, at an exercise price of $3.29 per share.
 
     On June 15, 1996, CVD extended a loan in the amount of $150,000, to Jeffrey
F. O'Donnell, the Company's Vice President of Sales and Marketing. The note was
secured by a second deed of trust on Mr. O'Donnell's home and has a five-year
term with interest compounding semi-annually at 6%. The principal and interest
will be due five years from the date of the note.
 
     On September 16, 1996, the Company extended an interest free loan to
Michael Henson in the amount of $175,000. The principal amount of the loan will
be due in full on September 19, 1998. The Company secured the note by a deed of
trust on certain real property owned by Mr. Henson.
 
     On January 24, 1997, the Company extended a loan in the amount of $100,000
to Jeffrey H. Thiel, the Company's Vice President of Operations. The note was
secured by a second deed of trust on Mr. Thiel's home and has a five-year term
with interest compounding semi-annually at 6%. The principal and interest will
be due five years from the date of the note.
 
     Edward M. Leonard and Gerard von Hoffmann, directors of the Company, are
members of the law firms of Brobeck, Phleger & Harrison LLP and Knobbe Martens,
Olson & Bear LLP, respectively. Both of these firms render legal services to the
Company.
 
     It is the Company's policy that all interested-party transactions,
including loans, between the Company and its officers, directors, principal
stockholders and their affiliates be approved by a majority of the Board of
Directors, including a majority of the independent and disinterested outside
directors on the Board of Directors.

                          DESCRIPTION OF CAPITAL STOCK
 
     The authorized capital stock of the Company consists of 30,000,000 shares
of Common Stock, $.001 par value, and 5,000,000 shares of Preferred Stock, $.001
par value.
 
COMMON STOCK
 
     As of April 15, 1997, there were 9,103,459 shares of Common Stock
outstanding that were held of record by 75 stockholders. The holders of Common
Stock are entitled to one vote per share on all matters to be voted upon by the
stockholders. Subject to preferences that may be applicable to any outstanding
Preferred Stock, the holders of Common Stock are entitled to receive ratably
such dividends, if any, as may be declared from time to time by the Board of
Directors out of funds legally available therefore. See "Dividend Policy." In
the event of the liquidation, dissolution or winding up of the Company, the
holders of Common Stock are entitled to share ratably in all assets remaining
after payment of liabilities, subject to prior distribution rights of Preferred
Stock, if any, then outstanding. The Common Stock has no preemptive or
conversion rights or other subscription rights. There are no redemption or
sinking fund provisions applicable to the Common Stock. All outstanding shares
of Common Stock are fully paid and nonassessable, and the shares of Common Stock
to be issued are fully paid and nonassessable.
 
PREFERRED STOCK
 
     The Company's Certificate of Incorporation authorizes 5,000,000 shares of
Preferred Stock. The Board of Directors has the authority to issue the Preferred
Stock in one or more series and to fix the rights, preferences, privileges and
restrictions thereof, including dividend rights, dividend rates, conversion
rights, voting rights, terms of redemption, redemption prices, liquidation
preferences and the number of shares constituting any series or the designation
of such series, without further vote or action by the stockholders. The issuance
of Preferred Stock may have the effect of delaying, deferring or preventing a
change in control of the Company without further action by the stockholders and
may adversely affect the voting and other rights of the holders of Common Stock.
The issuance of Preferred Stock with voting and conversion rights may adversely
affect the voting power of the holders of Common Stock, including the loss of
voting control to others. At present, the Company has no plans to issue any of
the Preferred Stock.
 
ANTITAKEOVER EFFECTS OF PROVISIONS OF THE CERTIFICATE OF INCORPORATION, BYLAWS
AND DELAWARE LAW
 
  Certificate of Incorporation and Bylaws
 
     The Certificate of Incorporation provides that all stockholder actions must
be effected at a duly called meeting and not by a consent in writing. The Bylaws
provide that the Company's stockholders may call a special meeting of
stockholders only upon a request of stockholders owning at least 50% of the
Company's capital stock. These provisions of the Certificate of Incorporation
and Bylaws could discourage potential acquisition proposals and could delay or
prevent a change in control of the Company. These provisions are intended to
enhance the likelihood of continuity and stability in the composition of the
Board of Directors and in the policies formulated by the Board of Directors and
to discourage certain types of transactions that may involve an actual or
threatened change of control of the Company. These provisions are designed to
reduce the vulnerability of the Company to an unsolicited acquisition proposal.
The provisions also are intended to discourage certain tactics that may be used
in proxy fights. However, such provisions could have the effect of discouraging
others from making tender offers for the Company's shares and, as a consequence,
they also may inhibit fluctuations in the market price of the Company's shares
that could result from actual or rumored takeover attempts. Such provisions also
may have the effect of preventing changes in the management of the Company. See
"Risk Factors -- Effect of Certain Charter Provisions; Antitakeover Effects of
Certificate of Incorporation, Bylaws and Delaware Law."
 
  Delaware Takeover Statute
 
     The Company is subject to Section 203 of the Delaware General Corporation
Law ("Section 203"), which, subject to certain exceptions, prohibits a Delaware
corporation from engaging in any business

combination with any interested stockholder for a period of three years
following the date that such stockholder became an interested stockholder,
unless: (i) prior to such date, the board of directors of the corporation
approved either the business combination or the transaction that resulted in the
stockholder becoming an interested stockholder; (ii) upon consummation of the
transaction that resulted in the stockholder becoming an interested stockholder,
the interested stockholder owned at least 85% of the voting stock of the
corporation outstanding at the time the transaction commenced, excluding for
purposes of determining the number of shares outstanding those shares owned (x)
by persons who are directors and also officers and (y) by employee stock plans
in which employee participants do not have the right to determine confidentially
whether shares held subject to the plan will be tendered in a tender or exchange
offer; or (iii) on or subsequent to such date, the business combination is
approved by the board of directors and authorized at an annual or special
meeting of stockholders, and not by written consent, by the affirmative vote of
at least 66 2/3% of the outstanding voting stock that is not owned by the
interested stockholder.
 
     Section 203 defines business combination to include: (i) any merger or
consolidation involving the corporation and the interested stockholder; (ii) any
sale, transfer, pledge or other disposition of 10% or more of the assets of the
corporation involving the interested stockholder; (iii) subject to certain
exceptions, any transaction that results in the issuance or transfer by the
corporation of any stock of the corporation to the interested stockholder; (iv)
any transaction involving the corporation that has the effect of increasing the
proportionate share of the stock of any class or series of the corporation
beneficially owned by the interested stockholder; or (v) the receipt by the
interested stockholder of the benefit of any loans, advances, guarantees,
pledges or other financial benefits provided by or through the corporation. In
general, Section 203 defines an interested stockholder as any entity or person
beneficially owning 15% or more of the outstanding voting stock of the
corporation and any entity or person affiliated with or controlling or
controlled by such entity or person.
 
TRANSFER AGENT AND REGISTRAR
 
     The Transfer Agent and Registrar for the Common Stock is ChaseMellon
Shareholder Services. Its address is 400 South Hope Street, Fourth Floor, Los
Angeles, CA 90071, and its telephone number is (213) 553-9700.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Sales of Common Stock in the public market during and after this offering
could adversely affect the market price of the Common Stock. As of April 15,
1997, the Company had 9,103,459 shares outstanding. Including all of the Shares
registered for sale hereby, 5,610,054 of the Company's outstanding shares are
freely tradable without restriction. Approximately 2,531,768 additional shares
are eligible for sale, including 1,809,768 shares held by EndoSonics, not
registered for sale hereunder, and 646,000 shares held by SCIMED. Sales of any
such shares in the public market could adversely affect the market price of the
Common Stock. The Company has also registered 1,200,000 shares of Common Stock
reserved for issuance under the Company's 1996 Stock Option/Stock Issuance Plan
and 200,000 shares under the Company's Employee Stock Purchase Plan. As of April
15, 1997, there were outstanding options under the Company's stock option plan
to acquire approximately 1,188,000 shares. SCIMED is entitled to certain demand
and piggyback registration rights with respect to its shares. If SCIMED, by
exercising its demand registration rights, causes a large number of shares to be
registered and sold in the public market, such sales could have an adverse
effect on the market price for the Common Stock. If the Company were required to
include in a Company-initiated registration shares held by SCIMED pursuant to
ffthe exercise of its piggyback registration rights, such sales may have an
adverse effect on the Company's ability to raise needed capital.
 
     In general, under Rule 144 of the Securities Act as currently in effect,
beginning 90 days after the consummation of the initial public offering, a
person (or persons whose shares are aggregated) who has beneficially owned
"restricted" shares for at least two years, including a person who may be deemed
an Affiliate of the Company, is entitled to sell within any three-month period a
number of shares of Common Stock that does not exceed the greater of 1% of the
then-outstanding shares of Common Stock of the Company and the average weekly
trading volume of the Common Stock on the Nasdaq National Market
 
                                       50

during the four calendar weeks preceding such sale. Sales under Rule 144 of the
Securities Act are subject to certain restrictions relating to manner of sale,
notice and the availability of current public information about the Company. A
person who is not an Affiliate of the Company at any time during the ninety days
preceding a sale, and who has beneficially owned shares for at least three
years, would be entitled to sell such shares immediately following the initial
public offering without regard to the volume limitations, manner of sale
provisions or notice or other requirements of Rule 144 of the Securities Act.
However, the transfer agent may require an opinion of counsel that a proposed
sale of shares comes within the terms of Rule 144 of the Securities Act prior to
effecting a transfer of such shares.
 
OPTIONS
 
     As of April 15, 1997, options to purchase a total of approximately 229,000
shares of Common Stock pursuant to the 1996 Stock Option Plan were outstanding
and exercisable and no additional shares of Common Stock were available for
future option grants or direct issuances under the 1996 Stock Option/Stock
Issuance Plan. See "Management -- 1996 Stock Option/Stock Issuance Plan," and
Notes 11 and 13 of Notes to Financial Statements.
 
     Rule 701 under the Securities Act provides that shares of Common Stock
acquired on the exercise of outstanding options may be resold by persons other
than Affiliates, beginning 90 days after the consummation of the initial public
offering, subject to the manner of sale provisions of Rule 144, and by
Affiliates, beginning 90 days after the date of this Prospectus, subject to all
provisions of Rule 144 except its two-year minimum holding period. On July 11,
1996, the Company filed a registration statement on Form S-8 under the
Securities Act to register all shares of Common Stock subject to outstanding
stock options and Common Stock issued or issuable pursuant to the Company's 1996
Stock Option/Stock Issuance Plan and Common Stock issuable pursuant to the
Company's Employee Stock Purchase Plan. Shares covered by this registration
statement are eligible for sale in the public markets, subject to the Lock-up
Agreements, if applicable.
 
REGISTRATION RIGHTS
 
     SCIMED, the holder of 646,000 shares of Common Stock is entitled to certain
rights with respect to the registration of such shares under the Securities Act.
Under the terms of the agreement between the Company and SCIMED, if the Company
proposes to register any of its securities under the Securities Act, either for
its own account or for the account of other security holders exercising
registration rights, SCIMED is entitled to notice of such registration and is
entitled to include shares of such Common Stock therein. SCIMED may also require
the Company to file a registration statement under the Securities Act at the
Company's expense with respect to its shares of Common Stock, and the Company is
required to use its diligent reasonable efforts to effect such registration.
Further, SCIMED may require the Company to file additional registration
statements on Form S-3 at the Company's expense. These rights are subject to
certain conditions and limitations, among them the right of the underwriters of
an offering to limit the number of shares included in such registration in
certain circumstances.
 
     EndoSonics and CVD have entered into a Registration Rights Agreement in
connection with the acquisition of Cardiometrics by EndoSonics which provides
that CVD will use its best efforts to register under the Securities Act, the CVD
shares held by EndoSonics for distribution to Cardiometrics' stockholders in the
Merger. EndoSonics has agreed to bear all expenses incurred in connection with
such registration.
 
                              PLAN OF DISTRIBUTION
 
     The Company will receive no proceeds from this offering. The Shares offered
hereby may be distributed by EndoSonics directly to the former stockholders,
warrantholders and optionholders of Cardiometrics in connection with the

     Under applicable rules and regulations under the Exchange Act, any person
engaged in the distribution of the Shares may not simultaneously engage in
market making activities with respect to the Common Stock of the Company for a

applicable provisions of the Exchange Act and the rules and regulations
thereunder, including, without limitation, Regulation M, which provisions may
limit the timing of purchases and sales of shares of the Company's Common Stock
by EndoSonics.
 
     All of the Shares were originally issued by the Company to EndoSonics in
connection with the acquisition by EndoSonics of all of the outstanding capital
stock of the Company pursuant to an Agreement and Plan of Reorganization between
EndoSonics and the Company dated June 9, 1993, and in connection with the
acquisition by EndoSonics of 400,000 shares of the Company's Series B Preferred
Stock on March 29, 1996, which converted into 800,000 shares of Common Stock

issued pursuant to an exemption from the registration requirements of the
Securities Act of 1933, as amended (the "Securities Act"), provided by Section
4(2) thereof. The Shares are being registered by the Company pursuant to a
registration rights agreement by and between the Company and Endosonics entered
into in connection with the acquisition of Cardiometrics by EndoSonics.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Directors and Shareholders
CardioVascular Dynamics, Inc.
 
     We have audited the accompanying consolidated balance sheets of
CardioVascular Dynamics, Inc. and subsidiary as of December 31, 1995 and 1996,
and the related consolidated statements of operations, stockholders' equity (net
capital deficiency) and cash flows for each of the three years in the period
ended December 31, 1996. Our audits also included the financial statement
schedule listed in the Index at Item 16(b). These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
CardioVascular Dynamics, Inc. and subsidiary at December 31, 1995 and 1996, and
the consolidated results of its operations and its cash flows for each of the
three years in the period ended December 31, 1996, in conformity with generally
accepted accounting principles. Also, in our opinion, the related financial
statement schedule, when considered in relation to the basic consolidated
financial statements taken as a whole, presents fairly in all material respects
the information set forth therein.

               (IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)
 
1. BUSINESS, BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING
POLICIES
 
  Business and Basis of Presentation
 
     CardioVascular Dynamics, Inc. (the "Predecessor") was incorporated on March
16, 1992 in the State of California. The Predecessor, and its successor
corporation discussed below, develops, manufactures and markets proprietary
therapeutic catheters used to treat certain vascular diseases.
 
     In June 1992, EndoSonics Corporation ("EndoSonics") acquired a 40%
preferred interest in the Predecessor. EndoSonics, a Delaware corporation,
develops, manufactures, and markets intravascular ultrasound imaging systems and
diagnostic, therapeutic and imaging catheters for the treatment of coronary and
peripheral vascular disease.
 
     In June 1993, EndoSonics acquired all of the remaining Preferred and Common
Stock of the Predecessor. The acquisition was accomplished through a merger
between the Predecessor and EndoSonics Acquisition Corp., a wholly owned
subsidiary of EndoSonics (which then changed its name to CardioVascular
Dynamics, Inc.) (hereinafter referred to as "CVD" or the "Company").
 
     The acquisition by EndoSonics resulted in a new basis for the CVD assets
and liabilities. Accordingly, the purchase price paid by EndoSonics has been
allocated to the identifiable assets and liabilities, including in-process
research and development, which was immediately expensed as no CVD products had
received regulatory approval and the technology did not have identifiable
alternative uses. The amount by which the purchase price exceeded the
Predecessor's net book value has been reflected as paid-in capital in the
accompanying financial statements. Pursuant to the terms of the original merger
agreement, in June 1995 EndoSonics issued an additional 50,000 shares of its
Common Stock to the former shareholders of the Predecessor. The fair market
value of such shares of $488 has been reflected in the accompanying financial
statements as an additional charge for acquired in-process technology.
 
     Subsequent to the acquisition, EndoSonics began performing certain services
for CVD (see Note 4), including general management, accounting, cash management,
and other administrative and engineering services. The amounts charged to CVD
for such services have been determined based on proportional cost allocations
and have been agreed to by the management of CVD and EndoSonics. In the opinion
of CVD's management, the allocation methods used are reasonable. Such
allocations, however, are not necessarily indicative of costs that would have
been incurred had CVD continued to operate independent of EndoSonics. No formal
agreement currently exists which specifies the nature of services to be provided
by EndoSonics to CVD, or the charges for such services. Therefore, amounts are
not necessarily indicative of the future charges to be incurred by CVD.
 
     In 1994 and 1996, the Board of Directors of CVD approved a 16,200-for-1 and
a 2-for-1 Common Stock split, respectively, which have been reflected
retroactively for all periods in the accompanying financial statements.
 
     On June 19, 1996, the Company closed its initial public offering (the
"Offering") which consisted of 3,400,000 shares of Common Stock at $12.00 per
share. On July 17, 1996, the Company's underwriters exercised their
overallotment option to purchase an additional 510,000 shares of Common Stock at
$12.00 per share. CVD received net offering proceeds from the sale of Common
Stock of approximately $42.8 million after deducting underwriting discounts and
commissions and other expenses of the Offering.
 
     In October 1996, CVD acquired 100% of the common stock of Intraluminal
Device, Inc. ("IDI") in exchange for CVD common stock valued at $1.4 million.
The acquisition was accomplished through the formation of IDI Acquisition, Inc.,
a wholly-owned subsidiary of CVD, and the merging of IDI into IDI Acquisition,
Inc. (See Note 2).

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The consolidated financial statements for December 31, 1996 include the
accounts of the Company and its subsidiary. Intercompany transactions have been
eliminated.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities 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.
 
  Cash and Cash Equivalents
 
     Cash and cash equivalents includes cash on hand, demand deposits, and
short-term investments with original maturities of three months or less.
 
  Marketable Securities Available-For-Sale
 
     The Company accounts for its investments pursuant to Statement of Financial
Accounting Standards No. 115, "Accounting for Certain Investments in Debt and
Equity Securities" ("SFAS 115").
 
     The Company has classified its entire investment portfolio as
available-for-sale. Available-for-sale securities are stated at fair value with
unrealized gains and losses included in shareholders' equity. The amortized cost
of debt securities is adjusted for amortization of premiums and accretions of
discounts to maturity. Such amortization is included in interest income.
Realized gains and losses are included in other income (expense). The cost of
securities sold is based on the specific identification method.
 
  Inventories
 
     Inventories are comprised of raw materials, work-in-process and finished
goods and are stated at the lower of cost, determined on an average cost basis,
or market value.
 
  Property and Equipment
 
     Property and equipment are stated at cost and depreciated or amortized on a
straight-line basis over the lesser of the estimated useful lives of the assets
or the lease term. The estimated useful lives range from three to seven years.
 
  Long-Lived Assets
 
     In March 1995, Statement of Financial Accounting Standards (SFAS) No. 121,
"Accounting for the Impairment of Long-Lived Assets to be Disposed of," was
issued. SFAS No. 121 requires that long-lived assets and certain identifiable
intangibles to be held and used or disposed of by an entity be reviewed for
impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. During 1996, the Company
adopted this statement and determined that no impairment loss need be recognized
for the applicable assets.
 
  Concentrations of Credit Risk and Significant Customers
 
     The Company maintains its cash and cash equivalents in deposit accounts and
in pooled investment accounts administered by a major financial institution.
 
     The Company sells its products primarily to medical institutions and
medical device distributors worldwide. The Company performs ongoing credit
evaluations of its customers' financial condition and

generally does not require collateral from customers. Management believes that
an adequate allowance for doubtful accounts has been provided.
 
     During 1994, 1995, and 1996 product sales to Fukuda Denshi Co., Ltd.,
("Fukuda"), the Company's Japanese distributor (see Note 5), comprised 61%, 18%
and 14% of total revenue. Accounts receivable from Fukuda represented 15% and 1%
of net accounts receivable at December 31, 1995 and 1996, respectively.
 
     Product sales to Medtronic, Inc. ("Medtronic") accounted for 21% of total
revenues during 1996. At December 31, 1996, 27% of accounts receivable were due
from Medtronic. One other customer comprised 12% of revenues for the year ended
December 31, 1995 and 14% of accounts receivable at December 31, 1995.
 
  Export Sales
 
     The Company had export sales by region as follows:

</TABLE>
 
  Revenue Recognition and Warranty
 
     The Company recognizes revenue from the sale of its products when the goods
are shipped to its customers. Reserves are provided for anticipated product
returns and warranty expenses at the time of shipment. License fees are
recognized on a contract with SCIMED Life Systems, Inc. ("SCIMED") when
distribution rights to certain markets are made available to SCIMED for the sale
of products based upon certain limited catheter technology. Contract revenues
are recognized on contracts with SCIMED and Advanced Cardiovascular Systems,
Inc. ("ACS") for transferring certain limited catheter technology based upon the
Company's completion of (1) technical assistance to aid SCIMED in manufacturing
the related products, and (2) research and development to develop the related
products for ACS and SCIMED (See Note 3).
 
  Accounting for Stock-Based Compensation
 
     The Company has elected to follow Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" (APB 25) and related
Interpretations in accounting for its employee stock options because, as
discussed below, the alternative fair value accounting provided for under FASB
Statement No. 123, "Accounting for Stock-Based Compensation," requires use of
option valuation models that were not developed for use in valuing employee
stock options. Under APB 25, because the exercise price of the Company's
employee stock options equals the market price of the underlying stock on the
date of grant, no compensation expense is recognized.
 
     Pro forma information regarding net income and earnings per share is
required by Statement 123, which also requires that the information be
determined as if the Company has accounted for its employee stock options
granted subsequent to December 31, 1994 under the fair value method of that
Statement. The fair value for these options was estimated at the date of grant
using the Black-Scholes option pricing model. The Black-Scholes 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
 
                                       F-9

                                      GG-61

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
subjective assumptions including the expected stock price volatility. Because
the Company's employee stock options 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 its employee stock options.
 
     In calculating pro forma information regarding net income and net income
per share the fair value was estimated at the date of grant using a
Black-Scholes option pricing model with the following weighted-average
assumptions for the options on the Company's common stock: risk-free interest
rate of 6.0%; a dividend yield of 0%; volatility of the expected market price of
the Company's common stock of 0.475; and a weighted-average expected life of the
options of 3.5 years.
 
     For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The Company's
pro forma information for the years ended December 31, 1995 and 1996 follows:
 
<TABLE>

                                                                        1995        1996
                                                                       -------     -------

</TABLE>
 
     Because Statement 123 is applicable only to options granted subsequent to
December 31, 1994, its pro forma effect will not be fully reflected until 1997.
 
  Income Taxes
 
     From June 1993 until June 1996, the Company's results of operations have
been included in consolidated tax returns filed by EndoSonics. There was no
income tax provision for the consolidated tax group during the periods covered
by these financial statements. All net operating loss and credit carryforwards
and deferred tax assets and liabilities have been disclosed herein on a separate
company basis for CVD.
 
  Net Loss Per Share
 
     Pro forma net loss per share is computed using the weighted average number
of shares of Common Stock, convertible Preferred Stock (using the
as-if-converted method) and Common Stock issuable upon conversion of the
Convertible Obligation, outstanding. Common equivalent shares from stock options
and warrants are not included as the effect is anti-dilutive, except that in
accordance with Securities and Exchange Commission Staff Accounting Bulletins,
common equivalents shares issued by the Company at prices substantially below
the anticipated initial public offering price during the period beginning one
year prior to the proposed public offering have been included in the calculation
as if they were outstanding for all periods presented (using the treasury stock
method and the estimated initial public offering price).
 
     For periods subsequent to the Company's initial public offering in June
1996, the Company's net loss per share has been calculated based on the weighted
average number of common and dilutive common equivalent shares outstanding.
Common Stock equivalents that are anti-dilutive are excluded from the
calculation.
 
  Reclassifications
 
     To conform with the 1996 financial statement presentation, certain
reclassifications have been made to the 1995 and 1994 financial statements.

2. ACQUISITION OF INTRALUMINAL DEVICES, INC.
 
     On October 16, 1996, the Company acquired all of the outstanding shares of
IDI in exchange for approximately 93,000 shares of CVD common stock valued at
$1.4 million. The acquisition was accounted for using the purchase method of
accounting. As the assets of IDI were patents for products still in their
development stage, the purchase price and the associated costs of acquisition
$0.7 million were expensed as acquired in-process research and development.
 
     The following table reflects unaudited pro forma combined results of
operations of the Company and IDI on the basis that the acquisition had taken
place and the related charge, noted above, was recorded at the beginning of 1996
as IDI operations were not material to the Company's operations prior to 1996:

     In management's opinion, the unaudited pro forma combined results of
operations are not indicative of the actual results that would have occurred had
the acquisition been consummated at the beginning of 1996 or of future
operations of the combined companies under the ownership and management of the
Company.
 
3. SCIMED LIFE SYSTEMS, INC.
 
     In September 1994, CVD and EndoSonics entered into a Stock Purchase and
Technology License Agreement with SCIMED. SCIMED acquired a 19% interest in CVD
in exchange for $2,500 in cash.
 
     CVD also granted SCIMED an exclusive license to certain patents in the
cardiovascular field of use, which allows SCIMED to manufacture the Transport
PTCA infusion catheter (the "Transport") developed by CVD in exchange for a
$1,000 license fee that was paid in 1994. SCIMED will pay royalties to CVD on
sales of the Transport and other products which use this patented technology.

     No options had been exercised and 125,000 options were exercisable at
December 31, 1995. As of December 31, 1996, 253,525 options were exercisable.
 
     The weighted-average grant-date fair value of options granted during 1995
and 1996, for options where the exercise price on the date of grant was equal to
the stock price on that date, was $0.40 and $5.12, respectively. The
weighted-average grant-date fair value of options granted during 1995 and 1996,
for options where the exercise price on the date of grant was less than the
stock price on that date, was $1.44 and $3.16, respectively.
 
     During 1995, the Company recorded deferred compensation of approximately
$345 for financial reporting purposes to reflect the difference between the
exercise price of certain options and the deemed fair value, for financial
statement presentation purposes, of the Company's shares of Common Stock. An
additional $150 of deferred compensation was recorded during the year ended
December 31, 1996. Deferred compensation is being amortized over the vesting
period of the related options. $119 of deferred compensation was amortized in
the year ended December 31, 1996.
 
  Stock Purchase Plan
 
     Under the terms of the Company's 1996 Employee Stock Purchase Plan (the
"Purchase Plan"), eligible employees can purchase Common Stock through payroll
deductions at a price equal to the lower of 85% of the fair market value of the
Company's Common Stock at the beginning or end of the applicable offering
period. A total of 200,000 shares of Common Stock are reserved for issuance
under the Purchase Plan.

     The valuation allowance increased by $1,569 and $1,072 in 1996 and 1995,
respectively.
 
     The Company's effective tax rate differs from the statutory rate of 35% due
to federal and state losses which were recorded without tax benefit.
 
     At December 31, 1996, the Company has net operating loss carryforwards for
federal and state income tax purposes of approximately $5,120,000 and $740,000,
respectively, which expire in the years 1997 through 2010. In addition, the
Company has research and development tax credits for federal and state income
tax purposes of approximately $256,000 and $144,000, respectively, which expire
in the years 2008 through 2010.
 
     Because of the "change of ownership" provision of the Tax Reform Act of
1986, utilization of the Company's net operating loss and research credit
carryforwards may be subject to an annual limitation against taxable income in
future periods. As a result of the annual limitation, a portion of these
carryforwards may expire before ultimately becoming available to reduce future
income tax liabilities.
 
13. EMPLOYEE BENEFIT PLAN
 
     The Company provides a 401(k) Plan for all employees 21 years of age or
older with over 3 months of service. Under the 401(k) Plan, eligible employees
voluntarily contribute to the Plan up to 15% of their salary through payroll
deductions. Employer contributions may be made by the Company at its discretion
based upon matching employee contributions, within limits, and profit sharing
provided for in the Plan. No employer contributions were made in 1996 and 1995.

                         CARDIOVASCULAR DYNAMICS, INC.
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
                                 MARCH 31, 1997
 
1. BASIS OF PRESENTATION
 
     Cardiovascular Dynamics, Inc. ("CVD" or the "Company") designs, develops,
manufactures and markets catheters used to treat certain vascular diseases. The
accompanying condensed consolidated financial statements have been prepared in
accordance with generally accepted accounting principles for interim financial
information and with the instructions to Form 10-Q and Article 10 of Regulation
S-X. Accordingly, they do not include all of the information and footnotes
required by generally accepted accounting principles for complete financial
statements. In the opinion of management, all adjustments (consisting of normal
recurring accruals) considered necessary for a fair presentation have been
included. Operating results for the three month period ended March 31, 1997 are
not necessarily indicative of results that may be expected for the year ending
December 31, 1997. For further information, refer to the consolidated financial
statements and footnotes thereto included in the Company's Annual Report on Form
10-K for the year ended December 31, 1996.
 
2. NET LOSS PER SHARE
 
     Pro forma net loss per share is computed using the weighted average number
of shares of Common Stock, Preferred Stock (using the as-if-converted method)
and Common Stock Issuable upon conversion of the Convertible Obligation,
outstanding. Common equivalent shares from stock options and warrants are not
included as the effect is anti-dilutive, except that in accordance with
Securities and Exchange Commission Staff Accounting Bulletins, common equivalent
shares issued by the Company at prices substantially below the anticipated
initial public offering price during the period beginning one year prior to the
offering have been included in the calculation as if they were outstanding for
all periods presented (using the treasury stock method and the initial public
offering price).
 
     For periods subsequent to the Company's initial public offering in June
1996, the Company's net loss per share has been calculated based on the weighted
average number of common and dilutive common equivalent shares outstanding.
Common stock equivalents that are anti-dilutive are excluded from the
calculation.
 
     In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, Earnings per Share, which is required to be adopted on December 31,
1997. At that time, the Company will be required to change the method currently
used to compute earnings per share and to restate all prior periods. Under the
new requirements for calculating primary earnings per share, the dilutive effect
of stock options will be excluded. The impact is not expected to result in a
change in earnings per share for the quarters ended March 31, 1997 and March 31,
1996 since the effect of stock options is anti-dilutive in the 1997 period and
the 1996 period includes the effect of stock options calculated pursuant to
requirements of the Securities and Exchange Commission for "cheap stock", which
are not changed as a result of the issuance of Statement No. 128. The impact of
Statement 128 on the calculation of fully diluted earnings per share for these
quarters is not expected to be material.
 
3. INVENTORIES
 
     Inventories are stated at the lower of cost, determined on an average cost
basis, or market value. Inventories consist of the following:

4. ACQUISITION OF INTRALUMINAL DEVICES, INC.
 
     On October 16, 1996, the Company acquired all of the outstanding shares of
Intraluminal Devices, Inc. (IDI) in a transaction accounted for as a purchase
for approximately 93,000 shares of the Company's common stock valued at $1.4
million. The entire purchase price was assigned to products in the development
stage and, together with acquisition costs of $0.7 million, were expensed as
acquired in-process research and development in the fourth quarter of 1996. Pro
forma combined results of the Company and IDI for the quarter ended March 31,
1996, on the basis that the acquisition had taken place at the beginning of
1996, would have reported a pro forma net loss of $463,000 and pro forma net
loss per share of $(0.10).

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 145 of the Delaware General Corporation Law, as amended (the
"DGCL"), provides that a corporation may indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal or investigative
(other than an action by or in the right of the corporation) by reason of the
fact that he is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding, if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful.
Section 145 further provides that a corporation similarly may indemnify any such
person serving in any such capacity who was or is a party or is threatened to be
made a party to any threatened, pending or completed action or suit by or in the
right of the corporation to procure a judgment in its favor, against expenses
actually and reasonably incurred in connection with the defense or settlement of
such action or suit if he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the corporation and
except that no indemnification shall be made in respect of any claim, issue or
matter as to which such person shall have been adjudged to be liable to the
corporation unless and only to the extent that the Delaware Court of Chancery or
such other court in which such action or suit was brought shall determine upon
application that, despite the adjudication of liability but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to
indemnify for such expenses which the Court of Chancery or such other court
shall deem proper.
 
     Section 102(b)(7) of the DGCL, permits a corporation to include in its
certificates of incorporation a provision eliminating or limiting the personal
liability of a director to the corporation or its stockholders for monetary
damages for breach of fiduciary duty as a director, provided that such provision
shall not eliminate or limit the liability of a director (i) for any breach of
the director's duty of loyalty to the corporation or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the DGCL (relating to
unlawful payment of dividends and unlawful stock purchases and redemption) or
(iv) for any transaction from which the director derived an improper personal
benefit.
 
     The Registrant's Certificate of Incorporation provides that the
Registrant's directors shall not be liable to the Registrant or its stockholders
for monetary damages for breach of fiduciary duty as a director, except to the
extent that exculpation from liabilities is not permitted under the DGCL as in
effect at the time such liability is determined. The Registrant has entered into
indemnification agreements with all of its officers and directors, as permitted
by the DGCL.

ITEM 22. UNDERTAKINGS.
 
     The undersigned registrant hereby undertakes:
 
     (1) to file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement: (i) to include any
prospectus required by Section 10(a)(3) of the Securities Act; (ii) to reflect
in the prospectus any facts or events arising after the effective date of this
Registration Statement (or the most recent post-effective amendment thereof)
which, individually or in the aggregate, represent a fundamental change in the
information set forth in this Registration Statement. Notwithstanding the
foregoing, any increase or decrease in volume of securities offered (if the
total dollar value of securities offered would not exceed that which was
registered) and any deviation from the low or high end of the estimated maximum
offering range may be reflected in the form of prospectus filed with the
Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume
and price represent no more than a 20 percent change in the maximum aggregate
offering price set forth in the "Calculation of Registration Fee" table in the
effective registration statement; and (iii) to include any material information
with respect to the plan of distribution not previously disclosed in this
Registration Statement or any material change to such information in this
Registration Statement;
 
     (2) that, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof;
 
     (3) to remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering;
 
                                      II-2
<PAGE>   296
 
     (4) that, for purposes of determining any liability under the Securities
Act, each filing of the Registrant's annual report pursuant to Section 13(a) or
Section 15(d) of the Exchange Act, that is incorporated by reference in this
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be a bona fide offering thereof;
 
     (5) that, prior to any public reoffering of the securities registered
hereunder through use of a prospectus which is a part of this Registration
Statement, by any person or party who is deemed to be an underwriter within the
meaning of Rule 145(c) of the Securities Act, such reoffering prospectus will
contain the information called for by the applicable registration form with
respect to reofferings by person who may be deemed underwriters, in addition to
the information called for by the other items of the applicable form;
 
     (6) that every prospectus (i) that is filed pursuant to paragraph (5)
immediately preceding, or (ii) that purports to meet the requirements of Section
10(a)(3) of the Securities Act and is used in connection with an offering of
securities subject to Rule 415 of the Securities Act, will be filed as a part of
an amendment to this Registration Statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act, each such post-effective amendment shall be deemed to
be a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof;
 
     (7) to respond to requests for information that is incorporated by
reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of Form S-4,
within one business day of receipt of such request, and to send the incorporated
documents by first class mail or other equally prompt means. This includes
information contained in documents filed subsequent to the effective date of
this Registration Statement through the date of responding to the request; and
 
     (8) to supply by means of a post-effective amendment all information
concerning a transaction, and the company being acquired involved therein, that
was not the subject of and included in this Registration Statement when it
became effective.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 20 above, or
otherwise, the Registrant has been informed that in the opinion of the
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

        Re:  Registration Statement on Form S-4

Ladies and Gentlemen:

        We have examined the Registration Statement on Form S-4 to be filed by
you with the Securities and Exchange Commission on or about the date hereof
(the "Registration Statement"), in connection with the registration under the
Securities Act of 1933, as amended, of 2,742,025 shares of Common Stock (the
"Shares") of Endosonics Corporation (the "Company") to be issued to the
stockholders of Cardiometrics, Inc. ("Cardiometrics") in connection with a
merger pursuant to which Cardiometrics would become a wholly-owned subsidiary
of the Company. As your counsel in connection with this transaction, we have
examined the proceedings taken and are familiar with the proceedings proposed
to be taken by you in connection with the issuance of the Shares.

        It is our opinion that, when issued in the manner referred to in the
Registration Statement and in accordance with the resolutions adopted by the
Board of Directors of the Company, such Shares will be legally and validly
issued, fully paid and nonassessable.

        We consent to the use of this Opinion as an exhibit to said
Registration Statement, and further consent to the use of our name wherever
appearing in said Registration Statement and in any amendment thereto.

                                       Very truly yours,



                                       BROBECK, PHLEGER & HARRISON LLP
