ITEM 1.  BUSINESS

OVERVIEW

     CardioThoracic Systems Inc. ("CTS" or the "Company") develops, 
manufactures, and markets  proprietary, disposable instruments and systems 
for performing minimally invasive cardiothoracic surgery. The Company's 
products are designed to enable the majority of cardiothoracic surgeons, 
using their existing skills coupled with Company sponsored training, to 
perform Minimally Invasive Direct Coronary Artery Bypass ("MIDCAB-TM-") 
surgery, an emerging minimally invasive revascularization procedure performed 
on a beating heart. The MIDCAB procedure eliminates the need for a heart-lung 
machine and recent studies indicate that the MIDCAB procedure reduces the 
trauma, procedural costs and post-surgical complications associated with 
coronary artery bypass graft ("CABG") surgery while providing long-term 
procedural success rates comparable to CABG surgery. 
     
     The main components of the CTS MIDCAB-TM- System  include: the ACCESS 
PLATFORM, which is designed to maximize access to the chest cavity through a 
mini-thoracotomy; the STABILIZER, which is designed to isolate and minimize 
the motion of the diseased artery; the LIMA LIFT, which is designed to offset 
the ribs to provide a window into the chest cavity so the surgeon can harvest 
the internal mammary artery (IMA); and the LIMA-LOOP, which is designed to 
enable the surgeon to reach into the chest cavity through the 
mini-thoracotomy and help isolate the IMA for harvest.
     
BACKGROUND

     Heart disease is the leading cause of death in America, with the 
American Heart Association reporting in 1995 that an estimated 11.2 million 
Americans have a history of coronary artery or other heart disease. Each 
year, approximately 1.4 million patients undergo a revascularization 
procedure to treat coronary artery disease. Coronary artery disease 
(atherosclerosis) is caused by cholesterol and other fatty materials becoming 
deposited on the walls of blood vessels, which form a build-up known as 
plaque. The heart needs a constant supply of oxygen and nutrients, which are 
carried by the blood in the coronary arteries. The accumulation of plaque 
narrows the interior of the blood vessels, thereby reducing blood flow to the 
heart muscle (the myocardium). When blood flow to the heart muscle becomes 
insufficient, an injury occurs, which may result in a heart attack 
(myocardial infarction) and often death.
     
     The heart has three main branches of coronary arteries: the left 
anterior descending artery ("LAD"), which descends from the left across the 
heart; the right coronary artery ("RCA"), which extends from the right of the 
heart around to the back of the heart; and the left circumflex artery, which 
extends from the left of the heart around to the back of the heart. The LAD 
is the primary blood supply to the heart and supplies blood to a large amount 
of the myocardium. Studies indicate that restoring blood flow to the LAD is 
the single most important determinant of long-term, event-free survival. 
Traditional treatments for coronary artery disease include drug therapy, 
coronary artery bypass graft ("CABG") surgery and catheter-based treatments, 
including balloon angioplasty, atherectomy and coronary stenting. CABG bypass 
surgery is highly invasive and traumatic to the patient, but is considered 
the most effective and long-lasting treatment for severe coronary artery 
disease. While catheter-based treatments are less invasive, the procedures 
are limited by high rates of restenosis, a renarrowing of the treated 
coronary artery, which generally requires reintervention. Catheter-based


                                       3
<PAGE>

treatments have been increasingly adopted because they are a less invasive 
treatment alternative. There are approximately 800,000 catheter-based 
procedures performed annually worldwide. Notwithstanding the introduction of 
less invasive catheter-based treatments, the Company believes that the number 
of patients treated by CABG surgery has continued to grow each year and that 
more than 600,000 CABG procedures are performed annually worldwide. The 
Company believes that many of the patients currently undergoing CABG surgery 
or catheter-based treatments are candidates for the MIDCAB procedure.
     
     DRUG THERAPY

     Drug therapy is a non-invasive treatment to improve blood flow and 
alleviate some of the symptoms associated with angina (chest pain). However, 
while some drug therapies may inhibit continued plaque build-up in the 
arteries, drug therapy is not a cure for heart disease. The various drugs 
utilized include nitroglycerin, beta blockers, calcium channel blockers and 
cholesterol lowering drugs. Although drug therapy is the least invasive 
treatment currently available, it is typically expensive because it must be 
chronically administered. Some patients suffer from side effects as well as 
require future interventional procedures.
     
     CORONARY ARTERY BYPASS GRAFT SURGERY

     CABG surgery is a treatment for severe cases of coronary artery disease 
in which blood vessel grafts are used to bypass the site of the blocked 
artery. This procedure restores blood flow by routing around a blockage using 
a healthy blood vessel from another part of the body. Although CABG surgery 
is highly effective in treating coronary artery disease, it is a highly 
invasive, traumatic and expensive procedure. In the United States the cost of 
undergoing CABG is approximately $36,000. The average post-operative hospital 
stay for a person undergoing a CABG procedure in the United States in 1994 
was five to seven days, and the average recuperation period following 
discharge from the hospital was approximately eight to ten weeks.
     
     The CABG procedure involves sawing the patient's sternum or breast bone 
in half, creating a twelve inch incision (sternotomy) for the purpose of 
exposing the patient's heart. The two halves are spread approximately six 
inches apart with a steel sternal retractor, and the heart is exposed. With a 
sternotomy, the heart is not directly under the incision and must be stopped 
prior to being moved into position for the procedure. Cannulae (plastic 
tubes) are inserted into the aorta and right atrium of the heart, a clamp is 
placed on the aorta to stop blood flow, and the heart is connected to a 
heart-lung machine to be slowly cooled and eventually stopped before the 
grafting can occur. The heart-lung machine is a series of interconnected 
specialty medical devices that together function as the patient's heart and 
lungs by temporarily circulating and oxygenating blood while the patient's 
own heart and lungs are rendered inactive. The patient's blood is circulated 
through plastic tubes to reservoirs in the heart-lung machine where carbon 
dioxide is removed, oxygen is replaced, and temperature is controlled. The 
patient's circulation is maintained on the external equipment throughout much 
of the CABG procedure, which averages three to six hours, depending on the 
patient's condition and number of grafts that must be created. Often patients 
undergo multiple vessel procedures, which may involve harvesting a saphenous 
vein from the leg and bypassing several blockages to achieve 
revascularization. When a saphenous vein is used as a graft, a continuous 
incision is often made from the ankle to the thigh of a patient's leg, the 
saphenous vein is dissected and removed, and the wound is sutured closed. A 
study involving over 1,000 patients indicates that the open harvesting of the 
saphenous vein (saphenectomy) results in wound healing impairment in 
approximately 24% of patients. As an


                                       4
<PAGE>

alternative to bypassing the blockage with a saphenous vein graft, an 
internal mammary artery ("IMA"), can be grafted directly on the coronary 
artery, bypassing the blocked section. At the conclusion of the CABG 
procedure, cannulae and the heart-lung machine are removed, the sternal 
halves are tied together with steel wire, and the skin is closed with suture 
material.
     
     Despite the invasiveness and trauma of the procedure, CABG is considered 
the most effective and long lasting treatment for severe coronary artery 
disease. Over 85% of bypass grafts formed from saphenous veins are patent 
(open) one year after surgery and over 60% are patent ten years after 
surgery. Grafts using the internal mammary arteries have patency rates of 
over 85% ten years after surgery and are well documented as being highly 
resistant to atherosclerosis.
     
     While every effort is made to minimize potential adverse effects from a 
procedure as traumatic as CABG surgery, published studies have shown that 
approximately 68% of all CABG surgeries have some complications. Some of the 
most severe complications can be attributed to the heart-lung machine 
including strokes, multiple organ dysfunction, inflammatory complications, 
respiratory failure and post-operative internal bleeding complications. It is 
estimated that stroke, which can have devastating functional consequences, 
occurs in approximately 5% of all CABG procedures. Another common 
complication of the use of the heart-lung machine is cognitive dysfunction, 
with patients experiencing significant loss of memory, attention span, verbal 
fluency, and psychomotor speed, even as long as six months after CABG 
surgery, regardless of attempts to mitigate or decrease the heart-lung 
machine time and trauma.
     
     Severe complications related to CABG procedures can also result from the 
sternotomy. Significant post-operative sternal infection usually requires 
reoperation and excision of the sternum and muscle flap. The rate of wound 
complications after sternotomy in a major study was 1.1% overall (72 patients 
out of 6,504), with 10 of those 72 dying before being discharged from the 
hospital. The patients with wound complications had a median length of 
hospital stay of 43 days, and triple the hospital costs of patients without 
such complications.
     
     CATHETER-BASED THERAPIES

     Catheter-based therapies, such as balloon angioplasty, atherectomy and 
coronary stenting, have become increasingly popular and effective over the 
last ten years. Balloon angioplasty is a procedure in which a balloon-tipped 
intravascular catheter is inserted into the femoral artery through a small 
incision in the upper thigh, is guided to the lesion (site of plaque) and 
then inflated and deflated several times to reshape the plaque and increase 
blood flow. Additional interventional devices for coronary artery disease 
include atherectomy devices (devices that cut or ablate and remove plaque 
from the arterial wall), laser catheter devices (devices that use laser 
energy to reduce plaque in arteries) and coronary stents (expandable metal 
frames that are positioned within the diseased area in the coronary artery to 
maintain the vessel opening). These treatments occur in a catheterization 
laboratory and are performed on a beating heart so they do not require a 
heart-lung machine. As a result, the length of stay and recuperation period 
are substantially less than those required with CABG. Currently, a common 
form of catheter-based treatment involves the use of balloon angioplasty 
followed by the placement of a coronary stent in the diseased artery. As a 
result of these minimally invasive approaches, patients are typically 
discharged within 24 to 48 hours and can return to a normal lifestyle within 
several days.
     
     While less invasive and traumatic than CABG, catheter-based therapies 
may not offer prolonged efficacy. Studies have indicated that within three to 
six months after a balloon angioplasty,


                                       5
<PAGE>

between 25% and 45% of patients experience restenosis (a renarrowing of the 
treated coronary artery). In addition, 5% to 7% of coronary balloon 
angioplasty patients experience abrupt reclosure of the treated vessel, which 
may be caused in part by flaps or tears of plaque that occur in the course of 
such treatment. In patients with multi-vessel coronary artery disease, a 
randomized study has shown that within three years of receiving treatment, 
only 7% of patients receiving CABG surgery required reintervention while 40% 
of patients receiving balloon angioplasty required reintervention. Additional 
studies have confirmed that approximately 20% of balloon angioplasty patients 
with multi-vessel disease will undergo CABG surgery within one year of 
receiving balloon angioplasty. However, the efficacy of catheter-based 
treatments may be improving. Recent multi-center studies indicated that 
restenosis rates after treatment with stents can be reduced by approximately 
30% as compared to balloon angioplasty alone. Future advancements in stents 
or other catheter-based treatments may further reduce restenosis rates.
     
     The average cost of a balloon angioplasty procedure in the United States 
is approximately $15,000 or less than one-half of the average cost of CABG 
surgery. In a recent study, the cost of balloon angioplasty was equivalent to 
that of CABG three years after the procedure, primarily due to the expense of 
reintervention for the balloon angioplasty patient. In addition, the use of 
stenting greatly increases the cost of a catheter-based procedure. One study 
indicated that the average cost per procedure for elective stenting was 
approximately twice the cost of balloon angioplasty treatment without 
stenting (or nearly equal to the cost of CABG surgery).
     
THE MIDCAB PROCEDURE

     Recently, a new procedure known as Minimally Invasive Direct Coronary 
Artery Bypass ("MIDCAB") has been developed that applies the techniques of 
minimally invasive intervention to CABG surgery. The Company believes that 
this procedure will provide patients with minimally invasive advantages 
similar to those of catheter-based procedures and clinical benefits 
comparable to those of CABG procedures. The Company believes the MIDCAB 
procedure offers the following benefits:
     
     ELIMINATES HEART-LUNG MACHINE.  Surgery is performed upon the beating 
heart, eliminating the need for a heart-lung machine. The heart-lung machine 
is a major contributing factor to the post-operative complications of CABG, 
which include stroke, bleeding and respiratory complications.
     
     MINIMALLY INVASIVE.  Access to the heart is provided through a small 
incision called a mini-thoracotomy, eliminating the need for a sternotomy, in 
which a twelve inch incision is made by sawing through the sternum or 
breastbone and spreading the ribcage apart to expose the heart. The healing 
of the sternum adds significantly to the recovery time for a CABG procedure, 
even in procedures without complications.

     PROVIDES DIRECT ACCESS.  Placement of the mini-thoracotomy provides 
access to the heart and the internal mammary arteries, permitting grafts to 
be performed under the surgeon's direct vision without the need for 
endoscopic equipment.

     REDUCES COSTS.  Studies indicate that fewer complications result in 
shorter hospital stays (approximately two days), less recuperation time 
(approximately two weeks) and reduced patient trauma relative to CABG 
surgery. The Company believes that the MIDCAB procedure represents a 


                                       6
<PAGE>

significant advancement in the delivery of coronary revascularization and 
will provide patients, payors and providers with a cost-effective alternative 
to existing interventional procedures.
     
     In the CTS MIDCAB procedure, the patient is placed under general 
anesthesia and a mini-thoracotomy is made just below the patient's breast, 
between the ribs. The procedure takes advantage of the fact that the heart 
and the arteries are located directly under the incision, unlike a 
conventional CABG procedure where the heart must be moved into position 
during the procedure. The LIMA Lift is inserted into the mini-thoracotomy and 
expanded to create an opening and offset the ribs. Under direct vision, 
without the need for endoscopic equipment, the surgeon then dissects the IMA 
from the chest wall. The IMA branches are gently exposed and are then clipped 
and cauterized. After the IMA is harvested to a satisfactory length the LIMA 
Lift is removed and the Access Platform is inserted into the chest opening. A 
small incision is then made in the pericardium (a fibrous, fluid filled sac 
that holds the heart in place in the chest cavity) and the coronary artery is 
exposed. The CTS MIDCAB procedure requires only a small pericardial incision, 
which allows the pericardium to continue to provide some support to the 
heart. The surgeon positions the Stabilizer at the grafting site isolating it 
and rendering it motionless. A small incision is made in coronary artery at 
the site of the grafting, and the IMA artery is grafted, under the surgeon's 
direct vision, onto the beating heart. After the grafting is complete, the 
pericardium and the chest are sewn shut and the procedure is complete. 
     
     Despite the potential benefits of the MIDCAB procedure for the treatment 
of coronary heart disease, it is currently performed by only a small number 
of cardiothoracic surgeons. The Company believes that most cardiothoracic 
surgeons have been reluctant to attempt the MIDCAB procedure because of, 
among other things, the difficulties of performing surgery on the beating 
heart. Of the procedures performed to date, the vast majority have been 
performed on a single artery, typically the LAD or, in substantially fewer 
instances, the RCA, and an extremely limited number have been performed on 
the circumflex artery. The LAD is the primary blood supply to the heart and 
supplies a large amount of the myocardium. Studies indicate that restoring 
blood flow to the LAD is the single most important factor in predicting 
long-term, event-free survival. As a result, the Company believes that many 
of the patients currently undergoing CABG surgery or catheter-based 
treatments are candidates for the MIDCAB procedure. A significant percentage 
of CABG procedures are performed on multiple vessels. To date, multiple 
vessel MIDCAB procedures have only been performed on an extremely limited 
basis, and there can be no assurance that the MIDCAB procedure will be 
effectively utilized for multiple bypasses on a more frequent basis. The 
Company is unable to predict how quickly, if at all, the MIDCAB procedure 
will be adopted by the medical community or, if it is adopted, the number of 
MIDCAB procedures that will be performed.
     
     Although the Company believes that the CTS MIDCAB procedure has 
significant advantages over competing procedures, broad-based clinical 
adoption of the procedure will not occur until physicians determine that the 
procedure is an attractive alternative to current treatments for coronary 
artery disease. The Company believes that physician endorsements will be 
essential for clinical adoption of this procedure, and there can be no 
assurance that any such endorsements will be obtained in a timely manner, if 
at all. Clinical adoption will also depend upon the Company's ability to 
facilitate training of cardiothoracic surgeons to perform minimally invasive 
bypass surgery on a beating heart, and the willingness of such surgeons to 
perform such a procedure. Patient acceptance of the procedure will depend in 
part upon physician recommendations as well as other factors, including the 
degree of invasiveness, the effectiveness of the procedure and rate and 
severity of complications associated with the procedure as compared to other 
treatments. Even if the clinical efficacy of the MIDCAB procedure is 
established, physicians may elect not to recommend the procedure unless 
acceptable reimbursement 

                                       7
<PAGE>

from health care payors is available. Health care payor acceptance may 
require evidence of the cost effectiveness of the MIDCAB procedure as 
compared to other currently available treatments. There can be no assurance 
that the MIDCAB procedure will gain clinical adoption. Failure of the MIDCAB 
procedure to achieve significant clinical adoption would have a material 
adverse effect on the Company's business, financial condition and results of 
operations.
     
THE CTS MIDCAB SYSTEM

     The Company's MIDCAB System is comprised of proprietary disposable 
surgical instruments designed to facilitate the MIDCAB procedure. The Company 
expects to accelerate the adoption of the MIDCAB procedure by marketing the 
CTS MIDCAB System that enables the majority of cardiothoracic surgeons, using 
their existing skills coupled with Company sponsored training, to perform the 
MIDCAB procedure. The CTS MIDCAB System is designed to provide the necessary 
access to the chest cavity, simplify the harvesting of the internal mammary 
artery, and optimize the conditions necessary for a quality graft to be 
performed on a beating heart. Key components of the CTS MIDCAB System include:

     THE ACCESS PLATFORM is designed to maximize access to the chest cavity 
through a mini-thoracotomy. The Access Platform creates an operating window 
into the chest cavity by smoothly retracting tissue and spreading the ribs 
for optimal exposure of the heart and arteries with minimal patient trauma.

     THE STABILIZER incorporates feet that are attached by a radial arm to 
the Access Platform. The Stabilizer is designed to apply slight pressure to 
the myocardium and thereby isolate the diseased artery, minimize the motion 
of the beating heart and permit the surgeon to complete the graft.
     
     THE LIMA-LIFT is a unique spreading system that offsets the ribs to 
provide a window into the chest cavity so the surgeon can harvest the IMA 
without using an endoscope.
     
     THE LIMA-LOOP enables a surgeon to reach into the chest to help isolate 
the IMA for harvest.
     
     The CTS MIDCAB System  is expected to account for the great majority of 
the Company's revenue for the foreseeable future. The Company has sold very 
little product in 1996, and there can be no assurance that the Company is 
capable of manufacturing the CTS MIDCAB System in commercial quantities at 
acceptable costs.  Nor can there be any assurance that demand for the CTS 
MIDCAB System will be sufficient to allow profitable operations. Failure of 
the CTS MIDCAB System to be successfully commercialized would have a material 
adverse effect on the Company's business, financial condition and results of 
operations.
     
SALES, MARKETING AND DISTRIBUTION

     The Company markets its products principally to cardiac surgeons.  The
Company's initial marketing strategy is to generate broad based market
acceptance of the MIDCAB procedure and the CTS MIDCAB System by sponsoring
educational programs, surgeon training programs and cultivating relationships
with opinion leaders in cardiac surgery. The Company has established a
Scientific Advisory Board comprised of cardiothoracic surgery opinion leaders,
prominent surgeons and leading interventional cardiologists. The members of the
Scientific Advisory Board participates in


                                       8
<PAGE>

Company-sponsored educational and training sessions, thereby encouraging 
acceptance of the MIDCAB procedure among cardiothoracic surgeons and the 
integration of the MIDCAB procedure into their hospital and surgical 
practices.
     
     The Company currently has a direct sales force of eight people in the 
United States which are supported by 6 clinical specialists. In December 1996 
the Company established CardioThoracic Systems, GmBH, a wholly owned 
subsidiary, in Dusseldorf Germany in order to build a direct sales and 
marketing organization for Germany.  In other markets, the Company will be 
selling its products primarily through distributors. 

CUSTOMER TRAINING 

     The Company believes that its Comprehensive Optimal Revascularization 
(COR) training and education program plays a important role in the adoption 
of the CTS MIDCAB procedure.  The Company has entered into agreements with 
three cardiac surgical centers in the United States and three in Europe to 
become COR Institutes.  The COR Institutes host a two-day, hands-on training 
workshop presented by recognized authorities in minimally invasive cardiac 
surgery.  The COR program teaches surgical teams key aspects of how to 
perform a MIDCAB procedure using the CTS MIDCAB System.  When the surgical 
team returns to their own hospital the Company's clinical specialist will 
provide additional training as required.  In 1997 the Company plans on 
establishing regional  COR  training programs in major metropolitan areas 
throughout the United States at non-hospital sites in order to increase the 
Company's ability to train surgeons.

RESEARCH AND DEVELOPMENT

     The Company is directing its research efforts toward development of 
proprietary surgical instruments and systems for cardiothoracic minimally 
invasive procedures, including coronary bypass, saphenous vein harvesting and 
valve repair and reconstruction. In addition, the Company is researching 
other methods of vessel attachment and stabilization of the beating heart. 
Most of the products under development will require regulatory clearance or 
approval prior to commercialization.  As of December 31, 1996, the Company's 
research and development staff consisted of 28 full-time engineers and 
technicians who have substantial experience in the development of medical 
devices, including expertise in the application of mechanical and electrical 
design principles to devices for cardiovascular applications. In addition, 
several of the Company's scientific advisors have prominent roles in 
directing the technical and medical research and development efforts at the 
Company.  Research and development expenses for the year ended December 31, 
1996 was $11.5 million.
     
MANUFACTURING

     To date, the Company's manufacturing activities have consisted only of 
building small quantities of the CTS MIDCAB System. As a result, the Company 
has no experience manufacturing the CTS MIDCAB System in the volumes that 
would be necessary for the Company to achieve significant commercial sales. 
There can be no assurance that reliable, high-volume manufacturing can be 
established or maintained at commercially reasonable costs.
     
     The Company's manufacturing facilities will be subject to GMP regulations,
international quality standards and other regulatory requirements. Difficulties
encountered by the Company in


                                       9
<PAGE>

manufacturing scale-up or failure by the Company to implement and maintain 
its facilities in accordance with GMP regulations, international quality 
standards or other regulatory requirements could entail a delay or 
termination of production, which could have a material adverse effect on the 
Company's business, financial condition and results of operations.
     
     The Company purchases most of the components for the CTS MIDCAB System 
from various independent suppliers that are either standard components or are 
built or molded to the Company's proprietary specifications.  In addition, 
the Company contracts with third parties for the performance of certain 
processes involved in the manufacturing cycle such as painting and finished 
product sterilization. Some of these components and processes may only be 
available from single-source vendors. Any prolonged supply interruption or 
yield problems experienced by the Company due to a single-source vendor could 
have a material adverse effect on the Company's ability to manufacture its 
products under development until a new source of supply is qualified. As the 
Company increases production, it may from time to time experience lower than 
anticipated yields or production constraints, resulting in delayed product 
shipments, which could adversely affect the Company's business, financial 
condition and results of operations.

PATENTS AND PROPRIETARY RIGHTS

     The Company's ability to compete effectively will depend in part on its 
ability to develop and maintain proprietary aspects of its technology. The 
Company owns two issued United States patents. The issued patents do not 
contain any claims that protect the CTS MIDCAB System. The Company is the 
licensee of a United States patent application for bipolar electrosurgical 
scissors that may be used in the IMA Harvester and the Saphenous Vein 
Harvesting System. The Company has filed twenty-one U.S. patent applications 
and various corresponding foreign patent applications. There can be no 
assurance that any issued patents or any patents which may be issued as a 
result of the Company's licensed patent application or United States and 
international patent applications will provide any competitive advantages for 
the Company's products or that they will not be successfully challenged, 
invalidated or circumvented in the future. In addition, there can be no 
assurance that competitors, many of which have substantial resources and have 
made substantial investments in competing technologies, will not seek to 
apply for and obtain patents that will prevent, limit or interfere with the 
Company's ability to make, use and sell its products either in the United 
States or in international markets.
     
     The medical device industry has been characterized by extensive 
litigation regarding patents and other intellectual property rights, and 
companies in the medical device industry have employed intellectual property 
litigation to gain a competitive advantage. There can be no assurance that 
the Company will not become subject to patent infringement claims or 
litigation or subject to interference proceedings declared by the United 
States Patent and Trademark Office ("USPTO") to determine the priority of 
inventions. The defense and prosecution of intellectual property suits, USPTO 
interference proceedings and related legal and administrative proceedings are 
both costly and time-consuming. Litigation may be necessary to enforce 
patents issued to the Company, to protect trade secrets or know-how owned by 
the Company or to determine the enforceability, scope and validity of the 
proprietary rights of others. Any litigation or interference proceedings will 
result in substantial expense to the Company and significant diversion of 
effort by the Company's technical and management personnel. An adverse 
determination in litigation or interference proceedings to which the Company 
may become a party, including any litigation that may arise against the 
Company as described in "Legal Proceedings" below, could subject the Company 
to significant liabilities to third parties or require the Company to seek 
licenses from third parties or prevent the Company from selling its products in


                                       10
<PAGE>

certain markets, or at all. Although patent and intellectual property 
disputes regarding medical devices have often been settled through licensing 
or similar arrangements, costs associated with such arrangements may be 
substantial and could include ongoing royalties. Furthermore, there can be no 
assurance that the necessary licenses would be available to the Company on 
satisfactory terms, if at all. Adverse determinations in a judicial or 
administrative proceeding or failure to obtain necessary licenses could 
prevent the Company from manufacturing and selling its products, which would 
have a material adverse effect on the Company's business, financial condition 
and results of operations.
     
     Congress enacted legislation, which became effective October 1, 1996, 
that places certain restrictions on the ability of medical device 
manufacturers to enforce certain patent claims, relating to surgical and 
medical methods, against medical practitioners. Such limitation in the 
enforceability of patent claims, relating to medical and surgical methods, 
against medical practitioners could have a material adverse effect on the 
Company's ability to protect its proprietary methods and procedures against 
medical practitioners.
     
     In addition to patents, the Company relies on trade secrets and 
proprietary know-how, which it seeks to protect, in part, through 
confidentiality and proprietary information agreements. There can be no 
assurance that such confidentiality or proprietary information agreements 
will not be breached, that the Company would have adequate remedies for any 
breach, or that the Company's trade secrets will not otherwise become known 
to or be independently developed by competitors.
     
COMPETITION

     The Company believes that the principal competitive factors in the 
market for treatment of cardiovascular disease are safety, efficacy, ease of 
use, reliability and cost effectiveness. The Company believes that the MIDCAB 
procedure performed with the CTS MIDCAB System will be substantially less 
costly than highly-invasive, traditional surgical procedures and may 
ultimately replace these procedures in some applications. The Company 
believes that the CTS MIDCAB System will enable surgeons to perform coronary 
bypass surgery less invasively, in a shorter period of time and with reduced 
patient trauma, resulting in reduced recuperation time in the ICU, shorter 
hospital stays and faster recovery, as well as lower complication rates. As a 
result, the Company believes that the CTS MIDCAB System will compete 
favorably with respect to each of these factors, although no assurance can be 
given that it will compete favorably.
     
     The medical device industry and the market for treatment of 
cardiovascular disease, in particular, are characterized by rapidly evolving 
technology and intense competition. A number of competitors including Johnson 
& Johnson, Boston Scientific Corporation, Cordis Corporation, Guidant 
Corporation and Medtronic, Inc. are currently marketing stents, catheters, 
lasers, drugs and other less invasive means of treating cardiovascular 
disease. Many of these less invasive treatments and CABG surgery are widely 
accepted in the medical community and have a long history of safe and 
effective use. Many of the Company's competitors have substantially greater 
capital resources, name recognition and expertise in and resources devoted to 
research and development, manufacturing and marketing and obtaining 
regulatory clearances or approvals. Furthermore, competition in the emerging 
market for minimally invasive cardiothoracic surgery is expected to be 
intense and to increase. Heartport, Inc., Medtronic, Inc., Research Medical 
Inc. and United States Surgical Corp. are marketing or have announced that 
they are developing products to be used in minimally invasive coronary 
procedures. There can be no assurance that the MIDCAB procedure will replace 
any current treatments. Additionally, even if it is widely adopted, there can 
be no assurance that the Company's competitors


                                       11
<PAGE>

will not succeed in developing alternative procedures and technologies, 
competing devices to perform the same procedure or therapeutic drugs that are 
more effective than the Company's products or that render the Company's 
products or technologies obsolete or not competitive. In addition, there can 
be no assurance that existing products for other surgical uses will not be 
used in MIDCAB procedures. Such competition could have a material adverse 
effect on the Company's business, financial condition and results of 
operations.
     
GOVERNMENT REGULATION

     The medical devices to be marketed and manufactured by the Company are 
subject to extensive regulation by the FDA, and, in some instances, by 
foreign governments. Pursuant to the Federal Food, Drug, and Cosmetic Act of 
1976, as amended, and the regulations promulgated thereunder (the "FDC 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. The 
FDA also has the authority to request repair, replacement or refund of the 
cost of any device manufactured or distributed by the Company.
     
     In the United States, medical devices are classified into three classes 
(Class I, II or III), on the basis of the controls deemed necessary by the 
FDA to reasonably assure their safety and effectiveness. Under FDA 
regulations, Class I devices are subject to general controls (for example, 
labeling, premarket notification and adherence to good manufacturing 
practices ("GMPs")) and Class II devices are subject to general and special 
controls (for example, 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 (for example, life-sustaining, life-supporting and 
implantable devices, or new devices which have not been found substantially 
equivalent to legally marketed devices).
     
     Before a new device can be introduced into the United States market, the 
manufacturer must generally obtain marketing clearance through either a 
510(k) premarket notification or a premarket approval ("PMA") application. 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 II medical device, or to a Class III medical device for which the 
FDA has not called for a PMA. The FDA may determine that a proposed device is 
not substantially equivalent to a legally marketed device, or that additional 
information or data are needed before a substantial equivalence determination 
can be made. A request for additional data may require that clinical studies 
of the device's safety and efficacy be performed. 
     
     Commercial distribution of a device for which a 510(k) premarket 
notification is required can begin only after the FDA issues an order finding 
the device to be "substantially equivalent" to a predicate device. The FDA 
has recently been requiring a more rigorous demonstration of substantial 
equivalence than in the past. It generally takes from four to twelve months 
from the date of submission to obtain a 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 information is 
needed before a substantial equivalence determination can be made.


                                       12
<PAGE>

     A "not substantially equivalent" determination, or a request for 
additional information, could delay the market introduction of new products 
that fall into this category and could have a materially adverse effect on 
the Company's business, financial condition and results of operations. For 
any of the Company's products that were cleared through the 510(k) process, 
modifications or enhancements that could significantly affect the safety or 
efficacy of the device or that constitute a major change to the intended use 
of the device will require new 510(k) submissions.
     
     A PMA application must be filed if a proposed device is not 
substantially equivalent to a legally marketed Class I or Class II device, or 
if it is a Class III device for which the FDA has called for PMAs. A PMA 
application must be supported by valid scientific evidence which typically 
includes extensive data, including human clinical trial data to demonstrate 
the safety and effectiveness of the device. The PMA application must also 
contain the results of all relevant bench tests, laboratory and animal 
studies, a complete description of the device and its components, and a 
detailed description of the methods, facilities and controls used to 
manufacture the device. In addition, the submission must include the proposed 
labeling, advertising literature and training methods (if required).
     
     Upon receipt of a PMA application, the FDA makes a threshold 
determination as to whether the application is sufficiently 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. Once the submission is accepted for filing, the 
FDA begins an in-depth review of the PMA. An FDA review of a PMA application 
generally takes one to two years from the date the PMA application is 
accepted for filing, but may take significantly longer. The review time is 
often significantly extended by the FDA asking for more information or 
clarification of information already provided in the submission. During the 
review period, an advisory committee, typically a panel of clinicians, will 
likely be convened to review and evaluate the application and provide 
recommendations to the FDA as to whether the device should be approved. The 
FDA is not bound by the recommendations of the advisory panel. Toward the end 
of the PMA review process, the FDA generally will conduct an inspection of 
the manufacturer's facilities to ensure that the facilities are in compliance 
with applicable GMP requirements.
     
     If the FDA's evaluations of both the PMA application and the 
manufacturing facilities are favorable, the FDA will either issue an approval 
letter or an approvable letter, which usually contains a number of conditions 
that must be met in order to secure final approval of the PMA. When and if 
those conditions have been fulfilled to the satisfaction of the FDA, the 
agency will issue a PMA approval letter, authorizing commercial marketing of 
the device for certain indications. If the FDA's evaluation of the PMA 
application or manufacturing facilities are not favorable, the FDA will delay 
approval of the PMA application or issue a "not approvable letter." The FDA 
may also determine that additional clinical trials are necessary, in which 
case PMA approval may be delayed for several years while additional clinical 
trials are conducted and submitted in an amendment to the PMA. The PMA 
process is expensive, uncertain and lengthy and a number of devices for which 
FDA approval has been sought by other companies have never been approved for 
marketing. 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.
     
     If human clinical trials of a device are required in connection with either
a 510(k) premarket notification or a PMA, and the device presents a "significant
risk," the sponsor of the trial (usually the


                                       13
<PAGE>

manufacturer or the distributor of the device) is required to file an 
investigational device exemption ("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 reviewed and approved by the FDA and one or more appropriate 
Institutional Review Boards ("IRBs"), human clinical trials may begin at a 
specific number of investigational sites with a specific number of patients, 
as approved by the FDA. If the device presents a "nonsignificant risk" to the 
patient, a sponsor may begin the clinical trial after obtaining approval for 
the study by one or more appropriate IRBs, but not the FDA. Sponsors of 
clinical trials are permitted to sell those devices distributed in the course 
of the study provided such compensation does not exceed recovery of the costs 
of manufacture, research, development and handling. An IDE supplement must be 
submitted to and approved by the FDA before a sponsor or an investigator may 
make a change to the investigational plan that may affect its scientific 
soundness or the rights, safety or welfare of human subjects.
     
     Any products manufactured or distributed by the Company 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. Device manufacturers are 
required to register their establishments and list their devices with the FDA 
and certain state agencies, and are subject to periodic inspections by the 
FDA and certain state agencies. The FDC Act requires devices to be 
manufactured in accordance with GMP regulations which impose certain 
procedural and documentation requirements upon the Company with respect to 
manufacturing and quality assurance activities. The FDA has recently 
finalized changes to the GMP regulations which will likely increase the cost 
of complying with GMP requirements.
     
     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. 
The Company and its products  are also subject to a variety of state laws and 
regulations in those states or localities where its products will be 
marketed. Any applicable state or local regulations may hinder the Company's 
ability to market its products in those states or localities. Manufacturers 
are also 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 the Company will not be 
required to incur significant costs to comply with such laws and regulations 
now or in the future or that such laws or regulations will not have a 
material adverse effect upon the Company's ability to do business.
     
     Exports of products that have market clearance from the FDA do not 
require export approval. However, some foreign countries require 
manufacturers to provide an FDA certificate for products for export ("CPE") 
which requires the device manufacturer to certify to the FDA that the product 
has been granted premarket clearance in the United States and that the 
manufacturing facilities appeared to be in compliance with GMPs at the time 
of the last GMP inspection. The FDA will refuse to issue a CPE if significant 
outstanding GMP violations exist.
     
     Exports of products subject to the 510(k) notification requirements, but 
not yet cleared to market, are permitted without FDA export approval provided 
certain requirements are met. Unapproved products subject to the PMA 
requirements must be approved by FDA for export. To obtain FDA export 
approval certain requirements must be met and information must be provided to 
the FDA, including documentation demonstrating that the product is approved 
for import into the country to which it is to be exported and, in some 
instances, safety data from animal or human studies. There


                                       14
<PAGE>

can be no assurance that the FDA will grant export approval when such 
approval is necessary, or that countries to which the devices are to be 
exported will approve the devices for import. Failure of the Company to 
obtain CPEs, meet the FDA's export requirements, or obtain FDA export 
approval when required to do so, could have a material adverse effect on the 
Company's business, financial condition and results of operations.
     
     The introduction of the Company's products in foreign markets will also 
subject the Company to foreign regulatory clearances, registrations or 
approvals which may impose additional substantial costs and burdens. 
International sales of medical devices are subject to the regulatory 
requirements of each country. The regulatory review process varies from 
country to country. Many countries also impose product standards, packaging 
requirements, labeling requirements and import restrictions on devices. In 
addition, each country has its own tariff regulations, duties and tax 
requirements. The approval by the FDA and foreign government authorities is 
unpredictable and uncertain, and no assurance can be given that the necessary 
clearances, registrations or approvals will be granted on a timely basis or 
at all. Delays in receipt of, or a failure to receive, such clearances, 
registrations or approvals, or the loss of any previously received, 
clearances, registrations or approvals, could have a material adverse effect 
on the business, financial condition and results of operations of the Company.
     
     The European Union has promulgated rules that require that medical 
products receive the right to affix the CE mark by mid-1998. The CE mark is 
an international symbol of adherence to quality assurance standards and 
compliance with applicable European medical device directives. In order to 
obtain the right to affix the CE mark to its current and future products, the 
Company will need to obtain certification that its processes meet ISO 9000 
quality standards. Failure to receive the right to affix the CE mark will 
prohibit the Company from selling its current or future products in member 
countries of the European Union after mid-1998. In January 1997 the Company 
received ISO 9001 certification and CE Mark approval for the CTS MIDCAB 
System.
     
     In May 1996 the Company was notified by the FDA that it is exempted from 
filing a premarket notification for the CTS Access Platform and the 
Stabilizer. In September 1996 the Company filed 510(k) premarket 
notifications for clearance to market additional components of the CTS MIDCAB 
System and the bipolar electrosurgical scissors.  In January 1997 the Company 
received clearance to market the bipolar electrosurgical scissors.  The 
Company intends to seek clearance to market additional components of the 
Saphenous Vein Harvesting System through 510(k) premarket notifications. 
There can be no assurance that the FDA will act favorably or quickly on the 
Company's 510(k) submissions, and significant difficulties and costs may be 
encountered by the Company in its efforts to obtain FDA clearance that could 
delay or preclude the Company from selling its potential products in the 
United States. Failure to receive, or delays in the receipt of FDA clearances 
or approvals could have a material adverse effect on the Company's business, 
financial condition and results of operations.
      
      The Company's products are subject to continued and pervasive 
regulation by the FDA and other foreign and domestic regulatory authorities. 
Changes in existing requirements or adoption of new requirements or policies 
could adversely affect the ability of the Company to comply with regulatory 
requirements. Failure to comply with regulatory requirements could have a 
material adverse effect on the Company's business, financial condition and 
results of operations. There can be no assurance that the Company will not be 
required to incur significant costs to comply with laws and regulations in 
the future or that laws or regulations will not have a material adverse 
effect upon the Company's business, financial condition or results of 
operations.


                                       15

THIRD-PARTY REIMBURSEMENT

     In the United States, health care providers, such as hospitals and 
physicians, that purchase medical devices, such as the Company's products 
under development, generally rely on third-party payors, principally 
Medicare, Medicaid and private health insurance plans, to reimburse all or 
part of the cost of the procedure in which the medical device is being used. 
Reimbursement for cardiovascular surgery, including CABG surgery, using 
devices that have received FDA approval has generally been available in the 
United States. In addition, certain health care providers are moving toward a 
managed care system in which such providers contract to provide comprehensive 
health care for a fixed cost per person. Although the Company believes that 
the cost of a MIDCAB procedure performed with the CTS MIDCAB System will be 
reimbursable under the current diagnosis-related group ("DRG") system, the 
Company is unable to predict what changes will be made in the reimbursement 
methods utilized by third-party health care payors. The Company anticipates 
that in a prospective payment system, such as the DRG system utilized by 
Medicare, and in many managed care systems used by private health care 
payors, the cost of the Company's products would be incorporated into the 
overall cost of the procedure and that there would be no separate, additional 
reimbursement for the Company's products. The Company anticipates that 
hospital administrators and physicians would justify the use of the Company's 
products by the attendant cost savings and clinical benefits that the Company 
believes would be derived from the use of its products. However, there can be 
no assurance that this will be the case. Furthermore, the Company could be 
adversely affected by changes in reimbursement policies of government or 
private health care payors, particularly to the extent any such changes 
affect reimbursement for the procedure in which the Company's products are 
intended to be used. Failure by physicians, hospitals and other potential 
users of the Company's products to obtain sufficient reimbursement from 
health care payors for the procedure in which the Company's products are 
intended to be used or adverse changes in government and private third-party 
payors' policies toward reimbursement for such procedures could have a 
material adverse effect on the Company's business, financial condition and 
results of operations.
     
     If the Company obtains the necessary foreign regulatory registrations or 
approvals, market acceptance of the Company's products in international 
markets would be dependent, in part, upon the availability of reimbursement 
within prevailing health care payment systems. Reimbursement and health care 
payment systems in international markets vary significantly by country, and 
include both government sponsored health care and private insurance. The 
Company intends to seek international reimbursement approvals, although there 
can be no assurance that any such approvals will be obtained in a timely 
manner, if at all, and failure to receive international reimbursement 
approvals could have a material adverse effect on market acceptance of the 
Company's products in the international markets in which such approvals are 
sought.
     
PRODUCT LIABILITY AND INSURANCE

     The development, manufacture and sale of medical products entail 
significant risk of product liability claims and product recalls. The 
Company's current product liability insurance coverage limits are $3,000,000 
per occurrence and $3,000,000 in the aggregate, and there can be no assurance 
that such coverage limits are adequate to protect the Company from any 
liabilities it might incur in connection with the development, manufacture 
and sale of its products. In addition, the Company may require increased 
product liability coverage as product sales increase.   Product liability 
insurance is expensive and in the future may not be available to the Company 
on acceptable terms, if at all. A successful


                                       16
<PAGE>

product liability claim or series of claims brought against the Company in 
excess of its insurance coverage or a product recall could have a material 
adverse effect on the Company's business, financial condition and results of 
operations.
     
EMPLOYEES

     As of December 31, 1996, the Company had 71 full-time employees. 
Twenty-eight persons are engaged in research and development and regulatory 
affairs activities, Nineteen persons are engaged in sales and marketing 
activities, fourteen persons are engaged in manufacturing and quality 
assurance and ten persons are engaged in finance and administration. No 
employees are covered by collective bargaining agreements, and the Company 
believes it maintains good relations with its employees.
     
OTHER FACTORS 

     This annual report on Form 10-K contains forward-looking statements 
within the meaning of Section 27A of the Securities Act of 1933 and Section 
21E of the Securities and Exchange Act of 1934.  The Company's future results 
could differ materially from those anticipated by such forward-looking 
statements as a result of certain factors including those set forth in the 
following factors and elsewhere in this annual report on Form 10-K.
     
     LIMITED OPERATING HISTORY; HISTORY OF LOSSES AND EXPECTATION OF FUTURE 
LOSSES.  The Company has a limited operating history upon which evaluation of 
its prospects can be made. Such prospects must be considered in light of the 
substantial risks, expenses and difficulties encountered by entrants into the 
medical device industry, which is characterized by an increasing number of 
participants, intense competition and a high failure rate. To date, the 
Company has engaged primarily in organizational and research and product 
development efforts, and a number of the Company's key management and 
technical personnel have only recently joined the Company.  The Company has 
only recently generated revenues and has very limited experience in 
manufacturing, marketing or selling the CTS MIDCAB System. The Company has 
experienced operating losses since its inception, and, as of December 31, 
1996, the Company had an accumulated deficit of approximately $17,075,000. 
The development and commercialization of the Company's products will require 
substantial development, regulatory, sales and marketing, manufacturing and 
other expenditures. The Company expects its operating losses to continue at 
least through 1997 as it continues to expend substantial resources to 
continue development of the Company's products, obtain additional regulatory 
clearances or approvals, build its marketing, sales, manufacturing and 
finance organizations and conduct further research and development. There can 
be no assurance that the Company's products will ever gain commercial 
acceptance or that the Company will ever generate revenues or achieve 
profitability.

     UNCERTAINTY OF CLINICAL ADOPTION OF MIDCAB PROCEDURE.  The Company's CTS 
MIDCAB System is designed to enable the majority of cardiothoracic surgeons, 
using their existing skills coupled with Company sponsored training, to 
perform the Minimally Invasive Direct Coronary Artery Bypass ("MIDCAB") 
procedure. Accordingly, the Company's success is dependent upon acceptance of 
the MIDCAB procedure by the medical community as a reliable, safe and cost 
effective alternative to existing treatments for revascularizing blocked 
coronary arteries. To date, the MIDCAB procedure has only been performed on a 
limited basis by a small number of highly skilled cardiothoracic surgeons. Of 
the procedures performed to date, the vast majority have been performed on a 
single artery, typically the left anterior descending artery ("LAD") or, in 
substantially fewer instances, the right coronary artery ("RCA"), and an 
extremely limited number have been performed on the circumflex artery. A 


                                       17
<PAGE>

significant percentage of coronary artery bypass graft ("CABG") procedures 
are performed on multiple vessels. To date, multiple vessel MIDCAB procedures 
have only been performed on an extremely limited basis, and there can be no 
assurance that the MIDCAB procedure will be effectively utilized for multiple 
bypasses on a more frequent basis. The Company is unable to predict how 
quickly, if at all, the MIDCAB procedure will be adopted by the medical 
community or, if it is adopted, the number of MIDCAB procedures that will be 
performed. The medical conditions that can be treated with the MIDCAB 
procedure can also be treated by widely accepted surgical procedures such as 
CABG surgery and catheter-based treatments, including balloon angioplasty, 
atherectomy and coronary stenting. Broad-based clinical adoption of the 
MIDCAB procedure will not occur until physicians determine that the procedure 
is an attractive alternative to current treatments for coronary artery 
disease. The Company believes that physician endorsements will be essential 
for clinical adoption of this procedure, and there can be no assurance that 
any such endorsements will be obtained in a timely manner, if at all. 
Clinical adoption will also depend upon the Company's ability to facilitate 
training of cardiothoracic surgeons to perform minimally invasive bypass 
surgery on a beating heart, and the willingness of such surgeons to perform 
such a procedure. Patient acceptance of the procedure will depend in part 
upon physician recommendations as well as other factors, including the degree 
of invasiveness, the effectiveness of the procedure and rate and severity of 
complications associated with the procedure as compared to other treatments. 
Even if the clinical efficacy of the MIDCAB procedure is established, 
physicians may elect not to recommend the procedure unless acceptable 
reimbursement from health care payors is available. Health care payor 
acceptance may require evidence of the cost effectiveness of the MIDCAB 
procedure as compared to other currently available treatments. There can be 
no assurance that the MIDCAB procedure will gain clinical adoption. Failure 
of the MIDCAB procedure to achieve significant clinical adoption would have a 
material adverse effect on the Company's business, financial condition and 
results of operations.
     
     DEPENDENCE ON THE MIDCAB SYSTEM; UNCERTAINTY OF MARKET ACCEPTANCE OF THE 
MIDCAB SYSTEM.  The CTS MIDCAB System is expected to account for the great 
majority of the Company's revenues for the foreseeable future. The Company 
has only recently commenced sales of  the CTS MIDCAB System, and there can be 
no assurance that market acceptance and demand for the CTS MIDCAB System will 
be sufficient to allow profitable operations. Failure of the CTS MIDCAB 
System to be successfully commercialized would have a material adverse effect 
on the Company's business, financial condition and results of operations.
     
     LACK OF REGULATORY APPROVALS.  The design, manufacturing, labeling, 
distribution and marketing of certain components of the CTS MIDCAB System and 
the Saphenous Vein Harvesting System will be subject to extensive and 
rigorous government regulation in the United States and certain other 
countries where the process of obtaining and maintaining required regulatory 
clearance or approvals is lengthy, expensive and uncertain. In order for the 
Company to market certain of its products under development in the United 
States, the Company must obtain clearance or approval from the United States 
Food and Drug Administration ("FDA"). The Company intends to seek clearance 
to market additional components of the CTS MIDCAB System and the bipolar 
electrosurgical scissors through a 510(k) premarket notification. The Company 
has been notified by the FDA that it is exempted from filing a premarket 
notification for the CTS Access Platform and the Stabilizer and is allowed to 
market these products in the United States. In September 1996 the Company 
filed 510(k) premarket notifications for clearance to market additional 
components of the CTS MIDCAB System and the bipolar scissors. In January 1997 
the Company received clearance from the FDA to market the bipolar 
electrosurgical scissors. There can be no assurance that the FDA will act 
favorably or quickly on the Company's remaining or future 510(k) submissions, 
or that significant difficulties and costs will not be


                                       18
<PAGE>

encountered by the Company in its efforts to obtain FDA clearance or 
approval. Any such difficulties could delay or preclude obtaining regulatory 
clearance or approval. In addition, there can be no assurance that the FDA 
will not impose strict labeling or other requirements as a condition of its 
510(k) clearance, any of which could limit the Company's ability to market 
its products. Further, if the Company wishes to modify a product after FDA 
clearance of a 510(k) premarket notification or approval of a PMA, including 
changes in indications or other modifications that could affect safety and 
efficacy, additional clearances or approvals will be required from the FDA. 
Failure to receive, or delays in receipt of, FDA clearances or approvals, 
including delays resulting from an FDA request for clinical trials or 
additional data as a prerequisite to clearance or approval, or any FDA 
conditions that limit the ability of the Company to market its products under 
development, could have a material adverse effect on the Company's business, 
financial condition and results of operations.
     
     In order for the Company to market its products in Europe and certain 
other international jurisdictions, the Company and its distributors and 
agents must obtain required regulatory registrations or approvals and 
otherwise comply with extensive regulations regarding safety, efficacy and 
quality. These regulations, including the requirements for registrations or 
approvals and the time required for regulatory review, vary from country to 
country. There can be no assurance that the Company will obtain regulatory 
registrations or approvals in such countries or that it will not be required 
to incur significant costs in obtaining or maintaining its foreign regulatory 
registrations or approvals. Delays in receipt of registrations or approvals 
to market the Company's products, failure to receive these registrations or 
approvals, or future loss of previously received registrations or approvals 
could have a material adverse effect on the Company's business, financial 
condition and results of operations.
     
     The European Union has promulgated rules that 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. In order to obtain the right 
to affix the CE mark to its products under development, the Company will need 
to obtain certification that its processes meet ISO 9000 quality standards.  
In January 1997 the Company received ISO 9001 certification and CE Mark 
approval for the CTS MIDCAB System.
     
     CONTINUING GOVERNMENT REGULATION.  Regulatory clearances or approvals, 
if granted, may include significant limitations on the indicated uses for 
which the products may be marketed. FDA enforcement policy strictly prohibits 
the marketing of FDA cleared or approved medical devices for unapproved uses. 
In addition, the Company's manufacturing processes will be required to comply 
with the Good Manufacturing Practices ("GMP") regulations of the FDA. These 
regulations include design, testing, production, control, documentation and 
other requirements. Enforcement of GMP regulations has increased 
significantly in the last several years, and the FDA has publicly stated that 
compliance will be more strictly scrutinized. The Company's facilities and 
manufacturing processes, as well as those of any future third-party 
suppliers, will be subject to periodic inspection by the FDA, the California 
Department of Health Services and other agencies. To date, the Company has 
only undergone inspection for ISO 9001 certification. Failure to comply with 
these and other applicable regulatory requirements could result in, among 
other things, warning letters, fines, injunctions, civil penalties, recall or 
seizure of products, total or partial suspension of production, refusal of 
the government to grant premarket clearance or premarket approval for 
devices, withdrawal of clearances or approvals and criminal prosecution, 
which could have a material adverse effect on the Company's business, 
financial condition and results of operations.

     HIGHLY COMPETITIVE MARKET; RISK OF ALTERNATIVE THERAPIES; RISK OF REUSE. 
The medical device industry and the market for treatment of cardiovascular 
disease, in particular, are characterized by rapidly evolving technology and 
intense competition. A number of competitors, including Johnson & Johnson, 
Boston Scientific Corporation, Cordis Corporation, Guidant Corporation and 
Medtronic, Inc., are currently marketing stents, catheters, lasers, drugs and 
other less invasive means of treating cardiovascular disease. Many of these 
less invasive treatments and CABG surgery are widely accepted in the medical 
community and have a long history of safe and effective use. Many of the 
Company's competitors have substantially greater capital resources, name 
recognition and expertise in and resources devoted to research and 
development, manufacturing and marketing and obtaining regulatory clearances 
or approvals. Furthermore, competition in the emerging market for minimally 
invasive cardiothoracic surgery is expected to be intense and to increase. 
Heartport, Inc., Medtronic, Inc., Research Medical Inc. and United States 
Surgical Corp. are marketing or have announced that they are developing 
products to be used in minimally invasive coronary procedures. There can be 
no assurance that the MIDCAB procedure will replace any current treatments. 
Additionally, even if it is widely adopted, there can be no assurance that 
the Company's competitors will not succeed in developing or marketing 
alternative procedures and technologies or competing devices to perform the 
same procedure or therapeutic drugs that are more effective than the 
Company's products or that render the Company's products or technologies 
obsolete or not competitive. In addition, there can be no assurance that 
existing products for other surgical uses will not be used in MIDCAB 
procedures. Furthermore, sales of the CTS MIDCAB System could be adversely 
affected by reuse of the Company's products, notwithstanding the instructions 
in the Company's clinical protocols and product labeling indicating that each 
of the components of the CTS MIDCAB System is a single-use device. Such 
competition or reuse could have a material adverse effect on the Company's 
business, financial condition and results of operations.
     
     DEPENDENCE ON LICENSES, PATENTS AND PROPRIETARY TECHNOLOGY.  The 
Company's ability to compete effectively will depend in part on its ability 
to develop and maintain proprietary aspects of its technology. The Company 
owns two issued United States patents. The issued patents do not contain any 
claims that protect the Company's products that are currently under 
development. The Company is the licensee of a United States patent 
application for bipolar electrosurgical scissors that are used in the 
Saphenous Vein Harvesting System. The Company has filed twenty-one patent 
applications. There can be no assurance that any issued patents or any 
patents which may be issued as a result of the Company's licensed patent 
application or United States and international patent applications will 
provide any competitive advantages for the Company's products or that they 
will not be successfully challenged, invalidated or circumvented in the 
future. In addition, there can be no assurance that competitors, many of 
which have substantial resources and have made substantial investments in 
competing technologies, will not seek to apply for and obtain patents that 
will prevent, limit or interfere with the Company's ability to make, use and 
sell its products either in the United States or in international markets.
     
     The medical device industry has been characterized by extensive 
litigation regarding patents and other intellectual property rights, and 
companies in the medical device industry have employed intellectual property 
litigation to gain a competitive advantage. There can be no assurance that 
the Company will not become subject to patent infringement claims or 
litigation or interference proceedings declared by the United States Patent 
and Trademark Office ("USPTO") to determine the priority of inventions. The 
defense and prosecution of intellectual property suits, USPTO interference 
proceedings and related legal and administrative proceedings are both costly 
and time-consuming. Litigation may be necessary to enforce patents issued to 
the Company, to protect trade secrets or know-


                                       20
<PAGE>

how owned by the Company or to determine the enforceability, scope and 
validity of the proprietary rights of others. Any litigation or interference 
proceedings will result in substantial expense to the Company and significant 
diversion of effort by the Company's technical and management personnel. An 
adverse determination in litigation or interference proceedings to which the 
Company may become a party, including any litigation that may arise against 
the Company as described in "Potential Litigation" below, could subject the 
Company to significant liabilities to third parties or require the Company to 
seek licenses from third parties or prevent the Company from selling its 
products in certain markets, or at all. Costs associated with settlements, 
licensing and similar arrangements, may be substantial and could include 
ongoing royalties. Furthermore, there can be no assurance that the necessary 
licenses would be available to the Company on satisfactory terms, if at all. 
Adverse determinations in a judicial or administrative proceeding or failure 
to obtain necessary licenses could prevent the Company from manufacturing and 
selling its products, which would have a material adverse effect on the 
Company's business, financial condition and results of operations.

     Congress enacted legislation, which became effective October 1, 1996, 
that places certain restrictions on the ability of medical device 
manufacturers to enforce certain patent claims, relating to surgical and 
medical methods, against medical practitioners. Such limitation in the 
enforceability of patent claims, relating to medical and surgical methods, 
against medical practitioners could have a material adverse effect on the 
Company's ability to protect its proprietary methods and procedures against 
medical practitioners.

     In addition to patents, the Company relies on trade secrets and 
proprietary know-how, which it seeks to protect, in part, through 
confidentiality and proprietary information agreements. There can be no 
assurance that such confidentiality or proprietary information agreements 
will not be breached, that the Company would have adequate remedies for any 
breach, or that the Company's trade secrets will not otherwise become known 
to or be independently developed by competitors.
     
     POTENTIAL LITIGATION.  Heartport, Inc. (formerly Stanford Surgical 
Technologies, Inc.), the former employer of the Company's founder and Chief 
Technical Officer, Charles S. Taylor, has alleged in certain correspondence 
that Mr. Taylor and the Company may have misappropriated trade secrets of the 
former employer and breached confidentiality obligations to the former 
employer. The former employer also claims an ownership interest in certain 
developments and products of the Company. The Company has agreed to provide 
for the defense of Mr. Taylor in the event that litigation is commenced. 
Litigation is subject to inherent uncertainties, especially in cases where 
complex technical issues are decided by a lay jury. Accordingly, no assurance 
can be given that if a lawsuit is commenced it would not be decided against 
the Company. Such an adverse determination could have a material adverse 
effect upon the Company's business, financial condition and results of 
operations.
     
     EARLY STAGE OF DEVELOPMENT AND COMMERCIALIZATION; NO ASSURANCE OF 
ABILITY TO MANAGE GROWTH.  The Company believes that the CTS MIDCAB System 
could address a large potential market. There can be no assurance that the 
Company's marketing efforts will result in significant demand for the CTS 
MIDCAB System , or that the initial demand for the Company's products will 
grow. Even if demand for the Company's products does grow, there can be no 
assurance that the Company will be able to develop the necessary 
manufacturing capability; build and train the necessary manufacturing, sales 
and marketing teams; attract, retain and integrate the required key 
personnel; or implement the financial and management systems to meet growing 
demand for its products. Failure of the Company to successfully manage its 
growth would have a material adverse effect on the Company's business, 
financial condition and results of operations.


                                       21
<PAGE>
     
     DEPENDENCE UPON KEY PERSONNEL.  The Company's ability to operate 
successfully depends in significant part upon the continued service of 
certain key scientific, technical, managerial and finance personnel, and its 
continuing ability to attract and retain additional highly qualified 
scientific, technical, managerial and finance personnel. Competition for such 
personnel is intense, and there can be no assurance that the Company can 
retain such personnel or that it can attract or retain other highly qualified 
scientific, technical, managerial and finance personnel in the future, 
including key manufacturing, sales and marketing personnel. The loss of key 
personnel or the inability to hire or retain qualified personnel could have a 
material adverse effect upon the Company's business, financial condition and 
results of operations. In addition, many employees of the Company, including 
a number of its key scientific, technical and managerial personnel, are 
subject to the terms of confidentiality agreements with respect to 
proprietary information of their former employers. The failure of these 
employees to comply with the terms of their agreements with, or other 
obligations to, such former employers could result in assertion of claims 
against the Company and such employees, which, if successful, could restrict 
their role with the Company and have a material adverse effect on the 
Company's business, financial condition and results of operations.
     
     DEPENDENCE UPON SCIENTIFIC ADVISORS.  The Company has established a 
Scientific Advisory Board including cardiothoracic surgery opinion leaders, 
prominent surgeons and leading interventional cardiologists who the Company 
believes have performed the vast majority of MIDCAB procedures. Members of 
the Scientific Advisory Board consult with the Company regarding research and 
development efforts at the Company, but are employed elsewhere on a full-time 
basis. As a result, they can only spend a limited amount of time on the 
Company's affairs. Although the Company has entered into consulting 
agreements, with terms ranging from six months to four years, and 
confidentiality agreements with each of the members of its Scientific 
Advisory Board, there can be no assurance that the consulting and 
confidentiality agreements between the Company and each of the members of the 
Scientific Advisory Board will not be terminated or breached, and there can 
be no assurance that any of such agreements will be renewed upon expiration.

     LIMITED SALES, MARKETING AND DISTRIBUTION EXPERIENCE.  The Company 
currently has a small sales and marketing organization. The Company intends 
to sell the CTS MIDCAB System in the United States and certain European 
countries through a direct sales force. In other markets, the Company intends 
to sell its products primarily through distributors or by means of 
collaborative arrangements. There can be no assurance that the Company will 
be able to build a larger direct sales force or marketing organization, that 
maintaining a direct sales force or marketing organization will be cost 
effective, or that the Company's sales and marketing efforts will be 
successful. There can be no assurance that the Company will be able to 
maintain agreements with distributors or collaborative arrangements, or that 
such distributors or collaborators will devote adequate resources to selling 
the Company's products under development. The Company has entered into 
distribution agreements for the sale of its products in certain countries, 
therefore the Company will be dependent upon the efforts of these third 
parties, and there can be no assurance that such efforts will be successful. 
Failure to build an effective sales and marketing organization or to 
establish effective distribution or collaborative relationships could have a 
material adverse effect on the Company's business, financial condition and 
results of operations.
     
     NO MANUFACTURING EXPERIENCE; SCALE-UP RISK.  The Company has no 
experience manufacturing its products in the volumes that would be necessary 
for the Company to achieve significant commercial sales. There can be no 
assurance that reliable, high-volume manufacturing can be established or


                                       22
<PAGE>

maintained at commercially reasonable costs. Companies often encounter 
difficulties in scaling up production, including problems involving 
production yield, quality control and assurance, and shortages of qualified 
personnel. In addition, the Company's manufacturing facilities will be 
subject to GMP regulations, international quality standards and other 
regulatory requirements. Difficulties encountered by the Company in 
manufacturing scale-up or failure by the Company to implement and maintain 
its facilities in accordance with GMP regulations, international quality 
standards or other regulatory requirements could entail a delay or 
termination of production, which could have a material adverse effect on the 
Company's business, financial condition and results of operations.
     
     POTENTIAL COMPONENT SHORTAGES; DEPENDENCE ON SOLE SOURCES OF SUPPLY.  
The Company contracts with third parties for the manufacture of certain 
components or the performance of certain processes involved in the 
manufacturing cycle. Some of these components and processes may only be 
available from single-source vendors. Any prolonged supply interruption or 
yield problems experienced by the Company due to a single-source vendor could 
have a material adverse effect on the Company's ability to manufacture its 
products under development until a new source of supply is qualified. As the 
Company increases production, it may from time to time experience lower than 
anticipated yields or production constraints, resulting in delayed product 
shipments, which could have a material adverse effect on the Company's 
business, financial condition and results of operation.
     
     UNCERTAINTY RELATING TO THIRD-PARTY REIMBURSEMENT.  In the United 
States, health care providers, such as hospitals and physicians, that 
purchase medical devices, such as the Company's products, generally rely on 
third-party payors, principally Medicare, Medicaid and private health 
insurance plans, to reimburse all or part of the cost of the procedure in 
which the medical device is being used. Reimbursement for cardiovascular 
surgery, including CABG surgery, using devices that have received FDA 
approval has generally been available in the United States. In addition, 
certain health care providers are moving toward a managed care system in 
which such providers contract to provide comprehensive health care for a 
fixed cost per person. The Company is unable to predict what changes will be 
made in the reimbursement methods utilized by third-party health care payors. 
The Company could be adversely affected by changes in reimbursement policies 
of government or private health care payors, particularly to the extent any 
such changes affect reimbursement for the procedures in which the Company's 
products are intended to be used. Failure by physicians, hospitals and other 
potential users of the Company's products under development to obtain 
sufficient reimbursement from health care payors for the procedure in which 
the Company's products are intended to be used or adverse changes in 
government and private third-party payors' policies toward reimbursement for 
such procedures could have a material adverse effect on the Company's 
business, financial condition and results of operations.
     
     Market acceptance of the Company's products in international markets 
will be dependent, in part, upon the availability of reimbursement within 
prevailing health care payment systems. Reimbursement and health care payment 
systems in international markets vary significantly by country, and include 
both government sponsored health care and private insurance. The Company 
intends to seek international reimbursement approvals, although there can be 
no assurance that any such approvals will be obtained in a timely manner, if 
at all, and failure to receive international reimbursement approvals could 
have a material adverse effect on market acceptance of the Company's products 
in the international markets in which such approvals are sought.
     
     RISKS RELATING TO INTERNATIONAL OPERATIONS.  The Company plans to market 
its products in international markets. Changes in overseas economic 
conditions, currency exchange rates, foreign tax


                                       23
<PAGE>

laws, or tariffs or other trade regulations could have a material adverse 
effect on the Company's business, financial condition and results of 
operations. The anticipated international nature of the Company's business is 
also expected to subject it and its representatives, agents and distributors 
to laws and regulations of the foreign jurisdictions in which they operate or 
the Company's products are sold. The regulation of medical devices in a 
number of such jurisdictions, particularly in the European Union, continues 
to develop 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. In addition, the laws of certain foreign countries do 
not protect the Company's intellectual property rights to the same extent as 
do the laws of the United States.
     
     PRODUCT LIABILITY RISK; LIMITED INSURANCE COVERAGE.  The development, 
manufacture and sale of medical products entail significant risk of product 
liability claims and product recalls. The Company's current product liability 
insurance coverage limits are $3,000,000 per occurrence and $3,000,000 in the 
aggregate, and there can be no assurance that such coverage limits are 
adequate to protect the Company from any liabilities it might incur in 
connection with the development, manufacture and sale of its products. In 
addition, the Company may require increased product liability coverage as 
product sales increase. Product liability insurance is expensive and in the 
future may not be available to the Company on acceptable terms, if at all. A 
successful product liability claim or series of claims brought against the 
Company in excess of its insurance coverage or a product recall could have a 
material adverse effect on the Company's business, financial condition and 
results of operations.
     
     POSSIBLE FUTURE CAPITAL REQUIREMENTS.  The Company's capital 
requirements depend on numerous factors, including the progress of the 
Company's product development programs, the receipt of and the time required 
to obtain regulatory clearances or approvals, the resources the Company 
devotes to developing, manufacturing and marketing its products, the extent 
to which the Company's products generate market acceptance and demand, and 
other factors. The Company expects to devote substantial capital resources 
for research and development, to hire and develop a larger direct sales force 
in the United States and to expand manufacturing capacity and facilities. The 
timing and amount of such capital requirements cannot be accurately 
predicted. Consequently, the Company may be required to raise additional 
funds through public or private financing, collaborative relationships or 
other arrangements. There can be no assurance that the Company will not 
require additional funding or that such additional funding, if needed, will 
be available on terms attractive to the Company, or at all, which could have 
a material adverse effect on the Company's business, financial condition and 
results of operations. Any additional equity financing may be dilutive to 
stockholders, and debt financing, if available, may involve restrictive 
covenants.
     
     POTENTIAL VOLATILITY OF STOCK PRICE.  The stock markets have experienced 
price and volume fluctuations that have particularly affected medical 
technology companies, resulting in changes in the market prices of the stocks 
of many companies that may not have been directly related to the operating 
performance of those companies. Such broad market fluctuations may adversely 
affect the market price of the Company's Common Stock. In addition, the 
market price of the Common Stock may be highly volatile. Factors such as 
variations in the Company's financial results, comments by securities 
analysts, announcements of technological innovations or new products by the 
Company or its competitors, changing government regulations and developments 
with respect to FDA submissions, patents, proprietary rights or litigation 
may have a significant adverse effect on the market price of the Common Stock.
     
     SIGNIFICANT RESTRICTIONS ON CHANGE OF CONTROL.  The Company has adopted 
a number of anti-


                                       24
<PAGE>

takeover measures.  The Company has adopted a Preferred Shares Rights 
Agreement, sometimes referred to as a poison pill, designed to prevent 
hostile takeovers not approved by the Board of Directors.  In addition, the 
company is authorized to issue 5,100,000 shares of undesignated Preferred 
Stock. Such shares of Preferred Stock may be issued by the Company without 
stockholder approval upon such terms as the Company's Board of Directors may 
determine.  The issuance of Preferred Stock may have the effect of delaying, 
deferring or preventing a change in control of the Company, may discourage 
bids for the Company's Common Stock at a premium over the market price of the 
Common Stock and may adversely affect the market price of and the voting and 
other rights of, the holders of Common Stock,  At present, the Company has no 
plans to issue any of the Preferred Stock.

ITEM 2.  PROPERTIES

     The Company currently leases a 23,500 square foot facility in Cupertino, 
California.  It includes an environmentally controlled, Class 10,000 clean 
room for assembly together with laboratory, machine shop, warehouse and 
office space. The lease expires on June 1, 2001.  The Company estimates this 
space to be sufficient through 1997 and is currently evaluating its 
requirements for 1998 and beyond.
     
ITEM 3.  LEGAL PROCEEDINGS
     
     The Company is not currently party to any legal proceeding.

     Heartport, Inc. (formerly Stanford Surgical Technologies, Inc.), the 
former employer of the Company's founder and Chief Technical Officer, Charles 
S. Taylor, has alleged in certain correspondence that Mr. Taylor and the 
Company may have misappropriated trade secrets of the former employer and 
breached confidentiality obligations to the former employer. The former 
employer also claimed an ownership interest in certain developments and 
products of the Company. The Company has agreed to provide for the defense of 
Mr. Taylor, in the event that litigation is commenced. The Company has 
conducted a review of its technology in light of the claims of the former 
employer and, after consultation with intellectual property counsel and with 
Mr. Taylor, believes that Mr. Taylor and the Company should prevail if 
litigation is commenced. However, litigation is subject to inherent 
uncertainties, especially in cases where complex technical issues are decided 
by a lay jury. Accordingly, no assurance can be given that, if a lawsuit is 
commenced, it would not be decided against the Company. Such an adverse 
determination could have a material adverse effect upon the Company's 
business, financial condition and results of operations.

    The board of directors may at any time establish branch or subordinate

business.


                                      ARTICLE II

                               MEETINGS OF STOCKHOLDERS

    2.1    PLACE OF MEETINGS

    Meetings of stockholders shall be held at any place within or outside the
State of Delaware designated by the board of directors.  In the absence of any
such designation, stockholders' meetings shall be held at the principal
executive office of the corporation.

    2.2    ANNUAL MEETING

    The annual meeting of stockholders shall be held each year on a date and at
a time designated by the board of directors.  In the absence of such
designation, the annual meeting of stockholders shall be held on the third
Thursday of May in each year at 10:00 a.m.  However, if such day falls on a
legal holiday, then the meeting shall be held at the same time and place on the

and any other proper business may be transacted.


<PAGE>

    2.3    SPECIAL MEETING

    A special meeting of the stockholders may be called at any time by the
board of directors, or by the chairman of the board, or by the president.  No
other person or persons are permitted to call a special meeting.

    If a special meeting is called by any person or persons other than the
board of directors, then the request shall be in writing, specifying the time of
such meeting and the general nature of the business proposed to be transacted,
and shall be delivered personally or sent by registered mail or by telegraphic
or other facsimile transmission to the chairman of the board, the president, or
the secretary of the corporation.  The officer receiving the request shall cause
notice to be promptly given to the stockholders entitled to vote, in accordance
with the provisions of Sections 2.4 and 2.6 of these bylaws, that a meeting will
be held at the time requested by the person or persons calling the meeting, so
long as that time is not less than thirty-five (35) nor more than sixty (60)
days after the receipt of the request.  If the notice is not given within twenty
(20) days after receipt of the request, then the person or persons requesting
the meeting may give the notice.  Nothing contained in this paragraph of this
Section 2.3 shall be construed as limiting, fixing or affecting the time when a
meeting of stockholders called by action of the board of directors may be held.

    2.4    NOTICE OF STOCKHOLDERS' MEETINGS

    All notices of meetings of stockholders shall be sent or otherwise given in
accordance with Section 2.6 of these bylaws not less than ten (10) nor more than
sixty (60) days before the date of the meeting.  The notice shall specify the
place, date and hour of the meeting and (i) in the case of a special meeting,
the purpose or purposes for which the meeting is called (no business other than
that specified in the notice may be transacted) or (ii) in the case of the
annual meeting, those matters which the board of directors, at the time of
giving the notice, intends to present for action by the stockholders (but any
proper matter may be presented at the meeting for such action).  The notice of
any meeting at which directors are to be elected shall include the name of any
nominee or nominees who, at the time of the notice, the board intends to present
for election.

    2.5    ADVANCE NOTICE OF STOCKHOLDER NOMINEES AND STOCKHOLDER BUSINESS

    Subject to the rights of holders of any class or series of stock having a
preference over the Common Stock as to dividends or upon liquidation,

    (a)    nominations for the election of directors, and

    (b)    business proposed to be brought before any stockholder meeting

may be made by the board of directors or proxy committee appointed by the board
of directors or by any stockholder entitled to vote in the election of directors
generally if such nomination or business proposed is otherwise proper business
before such meeting.  However, any such stockholder may nominate one or


                                         -2-

<PAGE>

more persons for election as directors at a meeting or propose business to be
brought before a meeting, or both, only if such stockholder has given timely
notice in proper written form of their intent to make such nomination or
nominations or to propose such business.  To be timely, such stockholder's
notice must be delivered to or mailed and received at the principal executive
offices of the corporation not less than one hundred twenty (120) calendar days
in advance of the date specified in the corporation's proxy statement released
to stockholders in connection with the previous year's annual meeting of
stockholders; provided, however, that in the event that no annual meeting was
held in the previous year or the date of the annual meeting has been changed by
more than thirty (30) days from the date contemplated at the time of the
previous year's proxy statement, notice by the stockholder to be timely must be
so received a reasonable time before the solicitation is made.  To be in proper
form, a stockholder's notice to the secretary shall set forth:

    (i)    the name and address of the stockholder who intends to make the
    nominations or propose the business and, as the case may be, of the
    person or persons to be nominated or of the business to be proposed;

    (ii)   a representation that the stockholder is a holder of record of
    stock of the corporation entitled to vote at such meeting and, if
    applicable, intends to appear in person or by proxy at the meeting to
    nominate the person or persons specified in the notice;

    (iii)  if applicable, a description of all arrangements or
    understandings between the stockholder and each nominee and any other
    person or persons (naming such person or persons) pursuant to which
    the nomination or nominations are to be made by the stockholder;

    (iv)   such other information regarding each nominee or each matter of
    business to be proposed by such stockholder as would be required to be
    included in a proxy statement filed pursuant to the proxy rules of the
    Securities and Exchange Commission had the nominee been nominated, or
    intended to be nominated, or the matter been proposed, or intended to
    be proposed by the board of directors; and

    (v)    if applicable, the consent of each nominee to serve as director
    of the corporation if so elected.

    The chairman of the meeting shall refuse to acknowledge the nomination of
any person or the proposal of any business not made in compliance with the
foregoing procedure.

    2.6    MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

    Written notice of any meeting of stockholders shall be given either
personally or by first-class mail or by telegraphic or other written
communication.  Notices not personally delivered shall be sent charges prepaid
and shall be addressed to the stockholder at the address of that stockholder
appearing on the books of the corporation or given by the stockholder to the
corporation for the purpose of notice.  Notice


                                         -3-

<PAGE>

shall be deemed to have been given at the time when delivered personally or
deposited in the mail or sent by telegram or other means of written
communication.

    An affidavit of the mailing or other means of giving any notice of any
stockholders' meeting, executed by the secretary, assistant secretary or any
transfer agent of the corporation giving the notice, shall be prima facie
evidence of the giving of such notice.

    2.7    QUORUM

    The holders of a majority in voting power of the stock issued and
outstanding and entitled to vote thereat, present in person or represented by
proxy, shall constitute a quorum at all meetings of the stockholders for the
transaction of business except as otherwise provided by statute or by the
certificate of incorporation.  If, however, such quorum is not present or
represented at any meeting of the stockholders, then either (i) the chairman of
the meeting or (ii) the stockholders entitled to vote thereat, present in person
or represented by proxy, shall have power to adjourn the meeting in accordance
with Section 2.7 of these bylaws.

    When a quorum is present at any meeting, the vote of the holders of a
majority of the stock having voting power present in person or represented by
proxy shall decide any question brought before such meeting, unless the question
is one upon which, by express provision of the laws of the State of Delaware or
of the certificate of incorporation or these bylaws, a different vote is
required, in which case such express provision shall govern and control the
decision of the question.

    If a quorum be initially present, the stockholders may continue to transact
business until adjournment, notwithstanding the withdrawal of enough
stockholders to leave less than a quorum, if any action taken is approved by a
majority of the stockholders initially constituting the quorum.

    2.8    ADJOURNED MEETING; NOTICE

    When a meeting is adjourned to another time and place, unless these bylaws
otherwise require, notice need not be given of the adjourned meeting if the time
and place thereof are announced at the meeting at which the adjournment is
taken.  At the adjourned meeting the corporation may transact any business that
might have been transacted at the original meeting.  If the adjournment is for
more than thirty (30) days, or if after the adjournment a new record date is
fixed for the adjourned meeting, a notice of the adjourned meeting shall be
given to each stockholder of record entitled to vote at the meeting.

    2.9    VOTING

    The stockholders entitled to vote at any meeting of stockholders shall be
determined in accordance with the provisions of Section 2.11 of these bylaws,

<PAGE>

    Except as may be otherwise provided in the certificate of incorporation or
these bylaws, each stockholder shall be entitled to one vote for each share of
capital stock held by such stockholder and stockholders shall not be entitled to
cumulate their votes in the election of directors or with respect to any matter
submitted to a vote of the stockholders.

    Notwithstanding the foregoing, if the stockholders of the corporation are
entitled, pursuant to Sections 2115 and 301.5 of the California Corporations
Code, to cumulate their votes in the election of directors, each such
stockholder shall be entitled to cumulate votes (i.e., cast for any candidate a
number of votes greater than the number of votes that such stockholder normally
is entitled to cast) only if the candidates' names have been properly placed in
nomination (in accordance with these bylaws) prior to commencement of the
voting, and the stockholder requesting cumulative voting has given notice prior
to commencement of the voting of the stockholder's intention to cumulate votes.
If cumulative voting is properly requested, each holder of stock, or of any
class or classes or of a series or series thereof, who elects to cumulate votes
shall be entitled to as many votes as equals the number of votes that (absent
this provision as to cumulative voting) he or she would be entitled to cast for
the election of directors with respect to his or her shares of stock multiplied
by the number of directors to be elected by him, and he or she may cast all of
such votes for a single director or may distribute them among the number to
be voted for, or for any two or more of them, as he or she may see fit.

    2.10   STOCKHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING

    Unless otherwise provided in the Certificate of Incorporation, any action
required or permitted to be taken at any annual or special meeting of
stockholders may be taken without a meeting, without prior notice and without a
vote, if a consent or consents in writing setting forth the action so taken,
shall be signed by the holders of outstanding stock having not less than the
minimum number of votes that would be necessary to authorize or take such action
at a meeting at which all shares entitled to vote thereon were present and
voted.  Such consents shall be delivered to the corporation by delivery to it
registered office in the state of Delaware, its principal place of business, or
an officer or agent of the corporation having custody of the book in which
proceedings of meetings of stockholders are recorded.  Delivery made to a
corporation's registered office shall be by hand or by certified or registered
mail, return receipt requested.

    2.11   RECORD DATE FOR STOCKHOLDER NOTICE; VOTING

    For purposes of determining the stockholders entitled to notice of any
meeting or to vote thereat, the board of directors may fix, in advance, a record
date, which shall not precede the date upon which the resolution fixing the
record date is adopted by the board of directors and which shall not be more
than sixty (60) days nor less than ten (10) days before the date of any such
meeting, and in such event only stockholders of record on the date so fixed are
entitled to notice and to vote, notwithstanding any transfer of any shares on
the books of the corporation after the record date.

    If the board of directors does not so fix a record date, the record date
for determining stockholders entitled to notice of or to vote at a meeting of
stockholders shall be at the close of business


                                         -5-

<PAGE>

on the business day next preceding the day on which notice is given, or, if
notice is waived, at the close of business on the business day next preceding
the day on which the meeting is held.

    A determination of stockholders of record entitled to notice of or to vote
at a meeting of stockholders shall apply to any adjournment of the meeting
unless the board of directors fixes a new record date for the adjourned meeting,
but the board of directors shall fix a new record date if the meeting is
adjourned for more than thirty (30) days from the date set for the original
meeting.

    The record date for any other purpose shall be as provided in Section 8.1
of these bylaws.

    2.12   PROXIES

    Every person entitled to vote for directors, or on any other matter, shall
have the right to do so either in person or by one or more agents authorized by
a written proxy signed by the person and filed with the secretary of the
corporation, but no such proxy shall be voted or acted upon after three (3)
years from its date, unless the proxy provides for a longer period.  A proxy
shall be deemed signed if the stockholder's name is placed on the proxy (whether
by manual signature, typewriting, telegraphic transmission, telefacsimile or
otherwise) by the stockholder or the stockholder's attorney-in-fact.  The
revocability of a proxy that states on its face that it is irrevocable shall be
governed by the provisions of Section 212(e) of the General Corporation Law of
Delaware.

    2.13   ORGANIZATION

    The president, or in the absence of the president, the chairman of the
board, or, in the absence of the president and the chairman of the board, one of
the corporation's vice presidents, shall call the meeting of the stockholders to
order, and shall act as chairman of the meeting.  In the absence of the
president, the chairman of the board, and all of the vice presidents, the
stockholders shall appoint a chairman for such meeting.  The chairman of any
meeting of stockholders shall determine the order of business and the procedures
at the meeting, including such matters as the regulation of the manner of voting
and the conduct of business.  The secretary of the corporation shall act as
secretary of all meetings of the stockholders, but in the absence of the
secretary at any meeting of the stockholders, the chairman of the meeting may
appoint any person to act as secretary of the meeting.

    2.14   LIST OF STOCKHOLDERS ENTITLED TO VOTE

    The officer who has charge of the stock ledger of the corporation shall
prepare and make, at least ten (10) days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder.  Such list shall be open
to the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten (10) days prior to
the meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held.  The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof, and may be inspected by any stockholder who is present.

    2.15   WAIVER OF NOTICE

    Whenever notice is required to be given under any provision of the General
Corporation Law of Delaware or of the certificate of incorporation or these
bylaws, a written waiver thereof, signed by the person entitled to notice,
whether before or after the time stated therein, shall be deemed equivalent to
notice.  Attendance of a person at a meeting shall constitute a waiver of notice
of such meeting, except when the person attends a meeting for the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened.  Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the stockholders need be specified in any written waiver of notice unless so
required by the certificate of incorporation or these bylaws.


                                     ARTICLE III

                                      DIRECTORS

    3.1    POWERS

    Subject to the provisions of the General Corporation Law of Delaware and to
any limitations in the certificate of incorporation or these bylaws relating to
action required to be approved by the stockholders or by the outstanding shares,
the business and affairs of the corporation shall be managed and all corporate
powers shall be exercised by or under the direction of the board of directors.


    3.2    NUMBER OF DIRECTORS

    The board of directors shall be not less than four (4) nor more than eight
(8) members.  The exact number of directors shall be eight (8) until changed,
within the limits specified above by a bylaw amending this Section 3.2 duly
adopted by the board of directors or by the stockholders.  The indefinite number
of directors may be changed, or a definite number may be fixed without provision
for an indefinite number, by an amendment to this bylaw, duly adopted by the
board of directors or by the stockholders, or by a duly adopted amendment to the
certificate of incorporation.

    No reduction of the authorized number of directors shall have the effect of
removing any director before that director's term of office expires.

    3.3    ELECTION AND TERM OF OFFICE OF DIRECTORS

    Except as provided in Section 3.4 of these bylaws, directors shall be
elected at each annual meeting of stockholders to hold office until the next
annual meeting. Each director, including a director elected or appointed to fill
a vacancy, shall hold office until the expiration of the term for which elected
and until a successor has been elected and qualified.


                                         -7-

<PAGE>

    3.4    RESIGNATION AND VACANCIES

    Any director may resign effective on giving written notice to the chairman
of the board, the president, the secretary or the board of directors, unless the
notice specifies a later time for that resignation to become effective.  If the
resignation of a director is effective at a future time, the board of directors
may elect a successor to take office when the resignation becomes effective.

    Vacancies in the board of directors may be filled by a majority of the
remaining directors, even if less than a quorum, or by a sole remaining
director; however, a vacancy created by the removal of a director by the vote of
the stockholders or by court order may be filled only by the affirmative vote of
a majority of the shares represented and voting at a duly held meeting at which
a quorum is present (which shares voting affirmatively also constitute a
majority of the required quorum).  Each director so elected shall hold office
until the next annual meeting of the stockholders and until a successor has been
elected and qualified.

    Unless otherwise provided in the certificate of incorporation or these
bylaws:

           (i)     Vacancies and newly created directorships resulting from any
increase in the authorized number of directors elected by all of the
stockholders having the right to vote as a single class may be filled by a
majority of the directors then in office, although less than a quorum, or by a
sole remaining director.

           (ii)    Whenever the holders of any class or classes of stock or
series thereof are entitled to elect one or more directors by the provisions of
the certificate of incorporation, vacancies and newly created directorships of
such class or classes or series may be filled by a majority of the directors
elected by such class or classes or series thereof then in office, or by a sole
remaining director so elected.

    If at any time, by reason of death or resignation or other cause, the
corporation should have no directors in office, then any officer or any
stockholder or an executor, administrator, trustee or guardian of a stockholder,
or other fiduciary entrusted with like responsibility for the person or estate
of a stockholder, may call a special meeting of stockholders in accordance with
the provisions of the certificate of incorporation or these bylaws, or may apply
to the Court of Chancery for a decree summarily ordering an election as provided
in Section 211 of the General Corporation Law of Delaware.

    If, at the time of filling any vacancy or any newly created directorship,
the directors then in office constitute less than a majority of the whole board
(as constituted immediately prior to any such increase), then the Court of
Chancery may, upon application of any stockholder or stockholders holding at
least ten (10) percent of the total number of the shares at the time outstanding
having the right to vote for such directors, summarily order an election to be
held to fill any such vacancies or newly created directorships, or to replace
the directors chosen by the directors then in office as aforesaid, which
election shall be governed by the provisions of Section 211 of the General
Corporation Law of Delaware as far as applicable.

    3.5    REMOVAL OF DIRECTORS

    Unless otherwise restricted by statute, by the certificate of incorporation
or by these bylaws, any director or the entire board of directors may be
removed, with or without cause, by the holders of a majority of the shares then
entitled to vote at an election of directors; provided, however, that, if and so
long as stockholders of the corporation are entitled to cumulative voting, if
less than the entire board is to be removed, no director may be removed without
cause if the votes cast against his removal would be sufficient to elect him if
then cumulatively voted at an election of the entire board of directors.

    3.6    PLACE OF MEETINGS; MEETINGS BY TELEPHONE

    Regular meetings of the board of directors may be held at any place within
or outside the State of Delaware that has been designated from time to time by

Delaware that has been designated in the notice of the meeting or, if not stated

the event such meeting is not held at the time and place so fixed by the
stockholders, the meeting may be held at such time and place as shall be
specified in a notice given as hereinafter provided for special meetings of the
board of directors, or as shall be specified in a written waiver signed by all
of the directors.

    3.8    REGULAR MEETINGS

    Regular meetings of the board of directors may be held without notice at
such time as shall from time to time be determined by the board of directors.

directors present at a duly held meeting at which a quorum is present shall be
regarded as the act of the board of directors, subject to the provisions of the
certificate of incorporation and applicable law.

business notwithstanding the withdrawal of directors, if any action taken is
approved by at least a majority of the quorum for that meeting.

meeting to the transaction of any business because the meeting is not lawfully
called or convened.  All such waivers shall be filed with the corporate records
or made part of the minutes of the meeting.  A waiver of notice need not specify
the purpose of any regular or special meeting of the board of directors.

board may designate one (1) or more directors as alternate members of any
committee, who may replace any absent or disqualified member at any meeting of
the committee.  The appointment of members or alternate members of a committee

of directors as provided in Section 151(a) of the General Corporation Law of
Delaware, fix the designations and any of the preferences or rights of such

assets of the corporation or the conversion into, or the exchange of such shares

the power or authority to declare a dividend, to authorize the issuance of
stock, or to adopt a certificate of ownership and merger pursuant to Section 253
of the General Corporation Law of Delaware.

    4.2    MEETINGS AND ACTION OF COMMITTEES

(notice of adjournment) and Section 3.14 (board action by written consent
without meeting), with such changes in the context of those bylaws as are

and its members; provided, however, that the time of regular meetings of
committees may be determined either by resolution of the board of directors or
by resolution of the committee, that special meetings of committees may also be
called by resolution of the board of directors, and that notice of special

                                   AND OTHER AGENTS

    6.1    INDEMNIFICATION OF DIRECTORS AND OFFICERS

    The corporation shall, to the maximum extent and in the manner permitted by
the General Corporation Law of Delaware as the same now exists or may hereafter
be amended, indemnify any person against expenses (including attorneys' fees),
judgments, fines, and amounts paid in settlement actually and reasonably
incurred in connection with any threatened, pending or completed action, suit,
or proceeding in which such person was or is a party or is threatened to be made
a party by reason of the fact that such person is or was a director or officer
of the corporation.  For purposes of this Section 6.1, a "director" or "officer"
of the corporation shall mean any person (i) who is or was a director or officer
of the corporation, (ii) who is or was serving at the request of the corporation
as a director or officer of another corporation, partnership, joint venture,
trust or other enterprise, or (iii) who was a director or officer of a

                                         -16-

<PAGE>

    The corporation shall be required to indemnify a director or officer in
connection with an action, suit, or proceeding (or part thereof) initiated by
such director or officer only if the initiation of such action, suit, or
proceeding (or part thereof) by the director or officer was authorized by the
Board of Directors of the corporation.

    The corporation shall pay the expenses (including attorney's fees) incurred
by a director or officer of the corporation entitled to indemnification
hereunder in defending any action, suit or proceeding referred to in this
Section 6.1 in advance of its final disposition; provided, however, that payment
of expenses incurred by a director or officer of the corporation in advance of
the final disposition of such action, suit or proceeding shall be made only upon
receipt of an undertaking by the director or officer to repay all amounts
advanced if it should ultimately be determined that the director of officer is
not entitled to be indemnified under this Section 6.1 or otherwise.

    The rights conferred on any person by this Article shall not be exclusive
of any other rights which such person may have or hereafter acquire under any
statute, provision of the corporation's Certificate of Incorporation, these
bylaws, agreement, vote of the stockholders or disinterested directors or
otherwise.

    Any repeal or modification of the foregoing provisions of this Article
shall not adversely affect any right or protection hereunder of any person in
respect of any act or omission occurring prior to the time of such repeal or
modification.

    6.2    INDEMNIFICATION OF OTHERS

    The corporation shall have the power, to the maximum extent and in the
manner permitted by the General Corporation Law of Delaware as the same now
exists or may hereafter be amended, to indemnify any person (other than
directors and officers) against expenses (including attorneys' fees), judgments,
fines, and amounts paid in settlement actually and reasonably incurred in
connection with any threatened, pending or completed action, suit, or
proceeding, in which such person was or is a party or is threatened to be made a
party by reason of the fact that such person is or was an employee or agent of
the corporation.  For purposes of this Section 6.2, an "employee" or "agent" of
the corporation (other than a director or officer) shall mean any person (i) who
is or was an employee or agent of the corporation, (ii) who is or was serving at
the request of the corporation as an employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, or (iii) who was an
employee or agent of a corporation which was a predecessor corporation of the
corporation or of another enterprise at the request of such predecessor
corporation.

    6.3    INSURANCE

    The corporation may purchase and maintain insurance on behalf of any person
who 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 any liability asserted against him or her and incurred
by him or her in any such capacity, or arising out of his or her status as such,
whether or not the corporation would have the power to indemnify him or her
against such liability under the provisions of the General Corporation Law of
Delaware.

    7.1    MAINTENANCE AND INSPECTION OF RECORDS

upon written demand under oath stating the purpose thereof, have the right
during the usual hours for business to inspect for any proper purpose the
corporation's stock ledger, a list of its stockholders, and its other books and
records and to make copies or extracts therefrom.  A proper purpose shall mean a
purpose reasonably related to such person's interest as a stockholder.  In every
instance where an attorney or other agent is the person who seeks the right to
inspection, the demand under oath shall be accompanied by a power of attorney or
such other writing that authorizes the attorney or other agent to so act on
behalf of the stockholder. The demand under oath shall be directed to the
corporation at its registered office in Delaware or at its principal place of
business.

records for a purpose reasonably related to his or her position as a director.

    7.3    ANNUAL STATEMENT TO STOCKHOLDERS

    The chairman of the board, if any, the president, any vice president, the
chief financial officer, the secretary or any assistant secretary of this
corporation, or any other person authorized by the board of directors or the
president or a vice president, is authorized to vote, represent and exercise on
behalf of this corporation all rights incident to any and all shares of the
stock of any other corporation or corporations standing in the name of this
corporation.  The authority herein granted may be exercised


                                         -18-

<PAGE>

either by such person directly or by any other person authorized to do so by
proxy or power of attorney duly executed by such person having the authority.

    The original or a copy of these bylaws, as amended or otherwise altered to
date, certified by the secretary, shall be kept at the corporation's principal

corporation, at all reasonable times during office hours.


                                     ARTICLE VIII

                                   GENERAL MATTERS

    8.1    RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING

    For purposes of determining the stockholders entitled to receive payment of
any dividend or other distribution or allotment of any rights or the
stockholders entitled to exercise any rights in respect of any change,
conversion or exchange of stock, or for the purpose of any other lawful action,
the board of directors may fix, in advance, a record date, which shall not
precede the date upon which the resolution fixing the record date is adopted and
which shall not be more than sixty (60) days before any such action.  In that
case, only stockholders of record at the close of business on the date so fixed
are entitled to receive the dividend, distribution or allotment of rights, or to
exercise such rights, as the case may be, notwithstanding any transfer of any
shares on the books of the corporation after the record date so fixed, except as
otherwise provided by law.

    If the board of directors does not so fix a record date, then the record
date for determining stockholders for any such purpose shall be at the close of
business on the day on which the board of directors adopts the applicable
resolution.

    8.2    CHECKS; DRAFTS; EVIDENCES OF INDEBTEDNESS

    From time to time, the board of directors shall determine by resolution
which person or persons may sign or endorse all checks, drafts, other orders for
payment of money, notes or other evidences of indebtedness that are issued in
the name of or payable to the corporation, and only the persons so authorized
shall sign or endorse those instruments.

    8.3    CORPORATE CONTRACTS AND INSTRUMENTS:  HOW EXECUTED

    The board of directors, except as otherwise provided in these bylaws, may
authorize and empower any officer or officers, or agent or agents, to enter into
any contract or execute any instrument in the name of and on behalf of the
corporation; such power and authority may be general or confined to specific
instances.  Unless so authorized or ratified by the board of directors or within
the agency power of an officer, no officer, agent or employee shall have any
power or authority to bind the corporation by


                                         -19-

<PAGE>

any contract or engagement or to pledge its credit or to render it liable for
any purpose or for any amount.

    8.4    STOCK CERTIFICATES; TRANSFER; PARTLY PAID SHARES

    The shares of the corporation shall be represented by certificates,
provided that the board of directors of the corporation may provide by
resolution or resolutions that some or all of any or all classes or series of
its stock shall be uncertificated shares.  Any such resolution shall not apply
to shares represented by a certificate until such certificate is surrendered to
the corporation.  Notwithstanding the adoption of such a resolution by the board
of directors, every holder of stock represented by certificates and, upon
request, every holder of uncertificated shares, shall be entitled to have a
certificate signed by, or in the name of the corporation by, the chairman or
vice-chairman of the board of directors, or the president or vice-president, and
by the treasurer or an assistant treasurer, or the secretary or an assistant
secretary of such corporation representing the number of shares registered in
certificate form.  Any or all of the signatures on the certificate may be a
facsimile.  In case any officer, transfer agent or registrar who has signed or
whose facsimile signature has been placed upon a certificate has ceased to be
such officer, transfer agent or registrar before such certificate is issued, it
may be issued by the corporation with the same effect as if he or she were such
officer, transfer agent or registrar at the date of issue.

    Certificates for shares shall be of such form and device as the board of
directors may designate and shall state the name of the record holder of the
shares represented thereby; its number; date of issuance; the number of shares
for which it is issued; a summary statement or reference to the powers,
designations, preferences or other special rights of such stock and the
qualifications, limitations or restrictions of such preferences and/or rights,
if any; a statement or summary of liens, if any; a conspicuous notice of
restrictions upon transfer or registration of transfer, if any; a statement as
to any applicable voting trust agreement; if the shares be assessable, or, if
assessments are collectible by personal action, a plain statement of such facts.

    Upon surrender to the secretary or transfer agent of the corporation of a
certificate for shares duly endorsed or accompanied by proper evidence of
succession, assignment or authority to transfer, it shall be the duty of the
corporation to issue a new certificate to the person entitled thereto, cancel
the old certificate and record the transaction upon its books.

    The corporation may issue the whole or any part of its shares as partly
paid and subject to call for the remainder of the consideration to be paid
therefor.  Upon the face or back of each stock certificate issued to represent
any such partly paid shares, or upon the books and records of the corporation in
the case of uncertificated partly paid shares, the total amount of the
consideration to be paid therefor and the amount paid thereon shall be stated.
Upon the declaration of any dividend on fully paid shares, the corporation shall
declare a dividend upon partly paid shares of the same class, but only upon the
basis of the percentage of the consideration actually paid thereon.


                                         -20-

<PAGE>

    8.5    SPECIAL DESIGNATION ON CERTIFICATES

    If the corporation is authorized to issue more than one class of stock or
more than one series of any class, then the powers, the designations, the
preferences and the relative, participating, optional or other special rights of
each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights shall be set forth in full or
summarized on the face or back of the certificate that the corporation shall
issue to represent such class or series of stock; provided, however, that,
except as otherwise provided in Section 202 of the General Corporation Law of
Delaware, in lieu of the foregoing requirements there may be set forth on the
face or back of the certificate that the corporation shall issue to represent
such class or series of stock a statement that the corporation will furnish
without charge to each stockholder who so requests the powers, the designations,
the preferences and the relative, participating, optional or other special
rights of each class of stock or series thereof and the qualifications,
limitations or restrictions of such preferences and/or rights.

    8.6    LOST CERTIFICATES

    Except as provided in this Section 8.6, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation and cancelled at the same time.  The board of
directors may, in case any share certificate or certificate for any other
security is lost, stolen or destroyed, authorize the issuance of replacement
certificates on such terms and conditions as the board may require; the board
may require indemnification of the corporation secured by a bond or other
adequate security sufficient to protect the corporation against any claim that
may be made against it, including any expense or liability, on account of the
alleged loss, theft or destruction of the certificate or the issuance of the
replacement certificate.

    8.7    TRANSFER AGENTS AND REGISTRARS

    The board of directors may appoint one or more transfer agents or transfer
clerks, and one or more registrars, each of which shall be an incorporated bank
or trust company -- either domestic or foreign, who shall be appointed at such
times and places as the requirements of the corporation may necessitate and the
board of directors may designate.

    8.8    CONSTRUCTION; DEFINITIONS

    Unless the context requires otherwise, the general provisions, rules of
construction and definitions in the General Corporation Law of Delaware shall
govern the construction of these bylaws.  Without limiting the generality of
this provision, as used in these bylaws, the singular number includes the
plural, the plural number includes the singular, and the term "person" includes
both an entity and a natural person.

                                      AMENDMENTS

    The original or other bylaws of the corporation may be adopted, amended or
repealed by the stockholders entitled to vote or by the board of directors of
the corporation.  The fact that such power has been so conferred upon the
directors shall not divest the stockholders of the power, nor limit their power
to adopt, amend or repeal bylaws.

    Whenever an amendment or new bylaw is adopted, it shall be copied in the
book of bylaws with the original bylaws, in the appropriate place.  If any bylaw
is repealed, the fact of repeal with the date of the meeting at which the repeal
was enacted or the filing of the operative written consent(s) shall be stated in
said book.

    4.   ADMINISTRATION OF THE PLAN.

         (a)  PROCEDURE.

                   (i)  MULTIPLE ADMINISTRATIVE BODIES.  The Plan may be
administered by different Committees with respect to different groups of Service
Providers.

                   (ii) SECTION 162(M). To the extent that the Administrator
determines it to be desirable to qualify Options granted hereunder as
"performance-based compensation" within the meaning of Section 162(m) of the
Code, the Plan shall be administered by a Committee of two or  more "outside
directors" within the meaning of Section 162(m) of the Code.

                                         -4-


<PAGE>

                   (iii) RULE 16B-3.  To the extent desirable to qualify 
transactions hereunder as exempt under Rule 16b-3, the transactions 
contemplated hereunder shall be structured to satisfy the requirements for 
exemption under Rule 16b-3.

                   (iv) OTHER ADMINISTRATION.  Other than as provided above,
the Plan shall be administered by (A) the Board or (B) a Committee, which
committee shall be constituted to satisfy Applicable Laws.  In addition, the
Board or Committee may authorize the Chief Executive Officer of the Company to
grant Options to newly-hired employees to purchase up to 15,000 Shares (subject
to adjustment as provided in Section 13) per Optionee and to fix the terms of
such Options within the limitations imposed by this Plan, the form of option
agreement approved by the Committee, and by the authorizing resolutions, and
subject to the following conditions:  (i) such Options must vest over four
years; and (ii) no such Options may be granted to an executive officer of the
Company or to an employee that reports directly to the Chief Executive Officer.

         (b)  POWERS OF THE ADMINISTRATOR.  Subject to the provisions of the
Plan, and in the case of a Committee, subject to the specific duties delegated
by the Board to such Committee, the Administrator shall have the authority, in
its discretion:

                   (i)  to determine the Fair Market Value;

                   (ii) to select the Service Providers to whom Options and
Stock Purchase Rights may be granted hereunder;

                   (iii) to determine the number of shares of Common Stock to 
be covered by each Option and Stock Purchase Right granted hereunder;

                   (iv) to approve forms of agreement for use under the Plan;

                   (v)  to determine the terms and conditions, not inconsistent
with the terms of the Plan, of any Option or Stock Purchase Right granted
hereunder.  Such terms and conditions include, but are not limited to, the
exercise price, the time or times when Options or Stock Purchase Rights may be
exercised (which may be based on performance criteria), any vesting acceleration
or waiver of forfeiture restrictions, and any restriction or limitation
regarding any Option or Stock Purchase Right or the shares of Common Stock
relating thereto, based in each case on such factors as the Administrator, in
its sole discretion, shall determine;

                   (vi) to reduce the exercise price of any Option or Stock
Purchase Right to the then current Fair Market Value if the Fair Market Value of
the Common Stock covered by such Option or Stock Purchase Right shall have
declined since the date the Option or Stock Purchase Right was granted;

                   (vii)     to institute an Option Exchange Program;

                                         -5-


<PAGE>

                   (viii) to construe and interpret the terms of the Plan and 
awards granted pursuant to the Plan;

                   (ix) to prescribe, amend and rescind rules and regulations
relating to the Plan, including rules and regulations relating to sub-plans
established for the purpose of qualifying for preferred tax treatment under
foreign tax laws;

                   (x)  to modify or amend each Option or Stock Purchase Right
(subject to Section 15(c) of the Plan), including the discretionary authority to
extend the post-termination exercisability  period of Options longer than is
otherwise provided for in the Plan;

                   (xi) to allow Optionees to satisfy withholding tax
obligations by electing to have the Company withhold from the Shares to be
issued upon exercise of an Option or Stock Purchase Right that number of Shares
having a Fair Market Value equal to the amount required to be withheld.  The
Fair Market Value of the Shares to be withheld shall be determined on the date
that the amount of tax to be withheld is to be determined.  All elections by an
Optionee to have Shares withheld for this purpose shall be made in such form and
under such conditions as the Administrator may deem necessary or advisable;

                   (xii)  to authorize any person to execute on behalf of the 
Company any instrument required to effect the grant of an Option or Stock 
Purchase Right previously granted by the Administrator;

                   (xiii)  to make all other determinations deemed necessary 
or advisable for administering the Plan.

         (c)  EFFECT OF ADMINISTRATOR'S DECISION.  The Administrator's
decisions, determinations and interpretations shall be final and binding on all
Optionees and any other holders of Options or Stock Purchase Rights.

    5.   ELIGIBILITY.  Nonstatutory Stock Options and Stock Purchase Rights may
be granted to Service Providers.  Incentive Stock Options may be granted only to
Employees.

    6.   LIMITATIONS.

         (a)  Each Option shall be designated in the Option Agreement as either
an Incentive Stock Option or a Nonstatutory Stock Option.  However,
notwithstanding such designation, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options.  For purposes of this
Section 6(a), Incentive Stock Options shall be taken into account in the order
in which they were granted.  The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.
              
                                         -6-


<PAGE>

         (b)  Neither the Plan nor any Option or Stock Purchase Right shall
confer upon an Optionee any right with respect to continuing the Optionee's
relationship as a Service Provider with the Company, nor shall they interfere in
any way with the Optionee's right or the Company's right to terminate such
relationship at any time, with or without cause.

         (c)  The following limitations shall apply to grants of Options:

                   (i)  No Service Provider shall be granted, in any fiscal
year of the Company, Options to purchase more than 500,000 Shares.

                   (ii) In connection with his or her initial service, a
Service Provider may be granted Options to purchase up to an additional 500,000
Shares which shall not count against the limit set forth in subsection (i)
above.

                   (iii)  The foregoing limitations shall be adjusted 
proportionately in connection with any change in the Company's capitalization 
as described in Section 13.

                   (iv) If an Option is cancelled in the same fiscal year of
the Company in which it was granted (other than in connection with a transaction
described in Section 13), the cancelled Option will be counted against the
limits set forth in subsections (i) and (ii) above.  For this  purpose, if the
exercise price of an Option is reduced, the transaction will be treated as a
cancellation of the Option and the grant of a new Option.

    7.   TERM OF PLAN.  Subject to Section 19 of the Plan, the Plan shall
become effective upon its adoption by the Board.  It shall continue in effect
for a term of ten (10) years unless terminated earlier under Section 15 of the
Plan.

    8.   TERM OF OPTION.  The term of each Option shall be stated in the Option
Agreement.  In the case of an Incentive Stock Option, the term shall be ten (10)
years from the date of grant or such shorter term as may be provided in the
Option Agreement.  Moreover, in the case of an Incentive Stock Option granted to
an Optionee who, at the time the Incentive Stock Option is granted, owns stock
representing more than ten percent (10%) of the voting power of all classes of
stock of the Company or any Parent or Subsidiary, the term of the Incentive
Stock Option shall be five (5) years from the date of grant or such shorter term
as may be provided in the Option Agreement.

    9.   OPTION EXERCISE PRICE AND CONSIDERATION.

         (a)  EXERCISE PRICE.  The per share exercise price for the Shares to
be issued pursuant to exercise of an Option shall be determined by the
Administrator, subject to the following:

                   (i)  In the case of an Incentive Stock Option

                                         -7-


<PAGE>

                        (A)  granted to an Employee who, at the time the
Incentive Stock Option is granted, owns stock representing more than ten percent
(10%) of the voting power of all classes of stock of the Company or any Parent
or Subsidiary, the per Share exercise price shall be no less than 110% of the
Fair Market Value per Share on the date of grant.

                        (B)  granted to any Employee other than an Employee
described in paragraph (A) immediately above, the per Share exercise price shall
be no less than 100% of the Fair Market Value per Share on the date of grant.

                   (ii) In the case of a Nonstatutory Stock Option, the per
Share exercise price shall be determined by the Administrator.  In the case of a
Nonstatutory Stock Option intended to qualify as "performance-based
compensation" within the meaning of Section 162(m) of the Code, the per Share
exercise price shall be no less than 100% of the Fair Market Value per Share on
the date of grant.

                   (iii) Notwithstanding the foregoing, Options may be 
granted with a per Share exercise price of less than 100% of the Fair Market 
Value per Share on the date of grant pursuant to a merger or other corporate 
transaction.

         (b)  WAITING PERIOD AND EXERCISE DATES.  At the time an Option is
granted, the Administrator shall fix the period within which the Option may be
exercised and shall determine any conditions which must be satisfied before the
Option may be exercised.

         (c)  FORM OF CONSIDERATION.  The Administrator shall determine the
acceptable form of consideration for exercising an Option, including the method
of payment.  In the case of an Incentive Stock Option, the Administrator shall
determine the acceptable form of consideration at the time of grant.  Such
consideration may consist entirely of:

                   (i)  cash;

                   (ii) check;

                   (iii) promissory note;

                   (iv) other Shares which (A) in the case of Shares acquired
upon exercise of an  option, have been owned by the Optionee for more than six
months on the date of surrender, and (B) have a Fair Market Value on the date of
surrender equal to the aggregate exercise price of the Shares as to which said
Option shall be exercised;

                   (v)  consideration received by the Company under a cashless
exercise program implemented by the Company in connection with the Plan;

                                         -8-


<PAGE>

                   (vi) a reduction in the amount of any Company liability to
the Optionee, including any liability attributable to the Optionee's
participation in any Company-sponsored deferred compensation program or
arrangement;

                   (vii) any combination of the foregoing methods of
payment; or

                   (viii) such other consideration and method of payment for
the issuance of Shares to the extent permitted by Applicable Laws.

    10.  EXERCISE OF OPTION.

         (a)  PROCEDURE FOR EXERCISE; RIGHTS AS A SHAREHOLDER. Any Option
granted hereunder shall be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the Administrator and set
forth in the Option Agreement.  Unless the Administrator provides otherwise,
vesting of Options granted hereunder shall be tolled during any unpaid leave of
absence.  An Option may not be exercised for a fraction of a Share.

              An Option shall be deemed exercised when the Company receives:
(i) written or electronic notice of exercise (in accordance with the Option
Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised.  Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan.  Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse. 
Until the Shares are issued (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company), no right
to vote or receive dividends or any other rights as a shareholder shall exist
with respect to the Optioned Stock, notwithstanding the exercise of the Option. 
The Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised.  No adjustment will be made for a dividend or other right
for which the record date is prior to the date the Shares are issued, except as
provided in Section 13 of the Plan.

              Exercising an Option in any manner shall decrease the number of
Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised.

         (b)  TERMINATION OF RELATIONSHIP AS A SERVICE PROVIDER.  If an
Optionee ceases to be a Service Provider, other than upon the Optionee's death
or Disability, the Optionee may exercise his or her Option within such period of
time as is specified in the Option Agreement to the extent that the Option is
vested on the date of termination (but in no event later than the expiration of
the term of such Option as set forth in the Option Agreement).  In the absence
of a specified time in the Option Agreement, the Option shall remain exercisable
for three (3) months following the Optionee's termination.  If, on the date of
termination, the Optionee is not vested as to his or her entire Option, the
Shares covered by the unvested portion of the Option shall revert to the Plan. 
If, after 

                                         -9-


<PAGE>

termination, the Optionee does not exercise his or her Option within the time
specified by the Administrator, the Option shall terminate, and the Shares
covered by such Option shall revert to the Plan.

         (c)  DISABILITY OF OPTIONEE.  If an Optionee ceases to be a Service
Provider as a result of  the Optionee's Disability, the Optionee may exercise
his or her Option within such period of time as is specified in the Option
Agreement to the extent the Option is vested on the date of termination (but in
no event later than the expiration of the term of such Option as set forth in
the Option Agreement).  In the absence of a specified time in the Option
Agreement, the Option shall remain exercisable for twelve (12) months following
the Optionee's termination.  If, on the date of termination, the Optionee is not
vested as to his or her entire Option, the Shares covered by the unvested
portion of the Option shall revert to the Plan.  If, after termination, the
Optionee does not exercise his or her Option within the time specified herein,
the Option shall terminate, and the Shares covered by such Option shall revert
to the Plan.

         (d)  DEATH OF OPTIONEE.  If an Optionee dies while a Service Provider,
the Option may be exercised within such period of time as is specified in the
Option Agreement (but in no event later than the expiration of the term of such
Option as set forth in the Notice of Grant), by the Optionee's estate or by a
person who acquires the right to exercise the Option by bequest or inheritance,
but only to the extent that the Option is vested on the date of death.  In the
absence of a specified time in the Option Agreement, the Option shall remain
exercisable for twelve (12) months following the Optionee's termination.  If, at
the time of death, the Optionee is not vested as to his or her entire Option,
the Shares covered by the unvested portion of the Option shall immediately
revert to the Plan.  The Option may be exercised by the executor or
administrator of the Optionee's estate or, if none, by the person(s) entitled to
exercise the Option under the Optionee's will or the laws of descent or
distribution.  If the Option is not so exercised within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

         (e)  BUYOUT PROVISIONS.  The Administrator may at any time offer to
buy out for a payment in cash or Shares, an Option previously granted based on
such terms and conditions as the Administrator shall establish and communicate
to the Optionee at the time that such offer is made.

    11.  STOCK PURCHASE RIGHTS.

         (a)  RIGHTS TO PURCHASE.  Stock Purchase Rights may be issued either
alone, in addition to, or in tandem with other awards granted under the Plan
and/or cash awards made outside of the Plan.  After the Administrator determines
that it will offer Stock Purchase Rights under the Plan, it shall advise the
offeree in writing or electronically, by means of a Notice of Grant, of the
terms, conditions and restrictions related to the offer, including the number of
Shares that the offeree shall be entitled to purchase, the price to be paid, and
the time within which the offeree must accept such offer.  The offer shall be
accepted by execution of a Restricted Stock Purchase Agreement in the form
determined by the Administrator.

                                         -10-


<PAGE>

         (b)  REPURCHASE OPTION.  Unless the Administrator determines
otherwise, the Restricted Stock Purchase Agreement shall grant the Company a
repurchase option exercisable upon the voluntary or involuntary termination of
the purchaser's service with the Company for any reason (including death or
Disability).  The purchase price for Shares repurchased pursuant to the
Restricted Stock purchase agreement shall be the original price paid by the
purchaser and may be paid by cancellation of any indebtedness of the purchaser
to the Company.  The repurchase option shall lapse at a rate determined by the
Administrator.

         (c)  OTHER PROVISIONS.  The Restricted Stock Purchase Agreement shall
contain such other terms, provisions and conditions not inconsistent with the
Plan as may be determined by the Administrator in its sole discretion.

         (d)  RIGHTS AS A SHAREHOLDER.  Once the Stock Purchase Right is
exercised, the purchaser shall have the rights equivalent to those of a
shareholder, and shall be a shareholder when his or her purchase is entered upon
the records of the duly authorized transfer agent of the  Company.  No
adjustment will be made for a dividend or other right for which the record date
is prior to the date the Stock Purchase Right is exercised, except as provided
in Section 13 of the Plan.

    12.  NON-TRANSFERABILITY OF OPTIONS AND STOCK PURCHASE RIGHTS.  Unless
determined otherwise by the Administrator, an Option or Stock Purchase Right may
not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any
manner other than by will or by the laws of descent or distribution and may be
exercised, during the lifetime of the Optionee, only by the Optionee.  If the
Administrator makes an Option or Stock Purchase Right transferable, such Option
or Stock Purchase Right shall contain such additional terms and conditions as
the Administrator deems appropriate.

    13.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, DISSOLUTION, MERGER OR
    ASSET SALE.

         (a)  CHANGES IN CAPITALIZATION.  Subject to any required action by the
shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option and Stock Purchase Right, and the number of shares of
Common Stock which have been authorized for issuance under the Plan but as to
which no Options or Stock Purchase Rights have yet been granted or which have
been returned to the Plan upon cancellation or expiration of an Option or Stock
Purchase Right, as well as the price per share of Common Stock covered by each
such outstanding Option or Stock Purchase Right, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration."  Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive. 
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall 

                                         -11-


<PAGE>

be made with respect to, the number or price of shares of Common Stock subject
to an Option or Stock Purchase Right.

         (b)  DISSOLUTION OR LIQUIDATION.  In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction.  The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option until ten (10) days prior to such
transaction as to all of the Optioned Stock covered thereby, including Shares as
to which the Option would not otherwise be exercisable.  In addition, the
Administrator may provide that any Company repurchase option applicable to any
Shares purchased upon exercise of an Option or Stock Purchase Right shall lapse
as to all such Shares, provided the proposed dissolution or liquidation takes
place at the time and in the manner contemplated.  To the extent it has not been
previously exercised, an Option or Stock Purchase Right will terminate
immediately prior to the consummation of such proposed action.

         (c)  MERGER OR ASSET SALE.  In the event of a merger of the Company
with or into another corporation, or the sale of substantially all of the assets
of the Company, each outstanding Option and Stock Purchase Right shall be
assumed or an equivalent option or right substituted by the successor
corporation or a Parent or Subsidiary of the successor corporation.  In the
event that the successor corporation refuses to assume or substitute for the
Option or Stock Purchase Right, the Optionee shall fully vest in and have the
right to exercise the Option or Stock Purchase Right as to all of the Optioned
Stock, including Shares as to which it would not otherwise be vested or
exercisable.  If an Option or Stock Purchase Right becomes fully vested and
exercisable in lieu of assumption or substitution in the event of a merger or
sale of assets, the Administrator shall notify the Optionee in writing or
electronically that the Option or Stock Purchase Right shall be fully  vested
and exercisable for a period of fifteen (15) days from the date of such notice,
and the Option or Stock Purchase Right shall terminate upon the expiration of
such period.  For the purposes of this paragraph, the Option or Stock Purchase
Right shall be considered assumed if, following the merger or sale of assets,
the option or right confers the right to purchase or receive, for each Share of
Optioned Stock subject to the Option or Stock Purchase Right immediately prior
to the merger or sale of assets, the consideration (whether stock, cash, or
other securities or property) received in the merger or sale of assets by
holders of Common Stock for each Share held on the effective date of the
transaction (and if holders were offered a choice of consideration, the type of
consideration chosen by the holders of a majority of the outstanding Shares);
provided, however, that if such consideration received in the merger or sale of
assets is not solely common stock of the successor corporation or its Parent,
the Administrator may, with the consent of the successor corporation, provide
for the consideration to be received upon the exercise of the Option or Stock
Purchase Right, for each Share of Optioned Stock subject to the Option or Stock
Purchase Right, to be solely common stock of the successor corporation or its
Parent equal in fair market value to the per share consideration received by
holders of Common Stock in the merger or sale of assets.

    14.  DATE OF GRANT.  The date of grant of an Option or Stock Purchase Right
shall be, for all purposes, the date on which the Administrator makes the
determination granting such Option or 

                                         -12-


<PAGE>

Stock Purchase Right, or such other later date as is determined by the
Administrator.  Notice of the determination shall be provided to each Optionee
within a reasonable time after the date of such grant.

    15.  AMENDMENT AND TERMINATION OF THE PLAN.

         (a)  AMENDMENT AND TERMINATION.  The Board may at any time amend,
alter, suspend or terminate the Plan. 

         (b)  SHAREHOLDER APPROVAL.  The Company shall obtain shareholder
approval of any Plan amendment to the extent necessary and desirable to comply
with Applicable Laws.

         (c)  EFFECT OF AMENDMENT OR TERMINATION.  No amendment, alteration,
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company. 
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers granted to it hereunder with respect to options granted under the
Plan prior to the date of such termination.

    16.  CONDITIONS UPON ISSUANCE OF SHARES. 

         (a)  LEGAL COMPLIANCE.  Shares shall not be issued pursuant to the
exercise of an Option or Stock Purchase Right unless the exercise of such Option
or Stock Purchase Right and the issuance and delivery of such Shares shall
comply with Applicable Laws and shall be further subject to the approval of
counsel for the Company with respect to such compliance.

         (b)  INVESTMENT REPRESENTATIONS.  As a condition to the exercise of an
Option or Stock Purchase Right, the Company may require the person exercising
such Option or Stock Purchase Right to represent and warrant at the time of any
such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required.

    17.  INABILITY TO OBTAIN AUTHORITY.  The inability of the Company to obtain
authority from any regulatory body having jurisdiction, which authority is
deemed by the Company's counsel to be necessary to the lawful issuance and sale
of any Shares hereunder, shall relieve the Company of any liability in respect
of the failure to issue or sell such Shares as to which such requisite authority
shall not have been obtained.

    18.  RESERVATION OF SHARES.  The Company, during the term of this Plan,
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

following schedule:

    [25% of the Shares subject to the Option shall vest twelve months after the

Date as provided above.

II.  AGREEMENT

    1.   GRANT OF OPTION.  The Plan Administrator of the Company hereby grants
to the Optionee named in the Notice of Grant attached as Part I of this
Agreement (the "Optionee") an option (the "Option") to purchase the number of
Shares, as set forth in the Notice of Grant, at the exercise price per share set
forth in the Notice of Grant (the "Exercise Price"), subject to the terms and
conditions of the Plan, which is incorporated herein by reference.  Subject to
Section 15(c) of the Plan, in the event of a conflict between the terms and
conditions of the Plan and the terms and conditions of this Option Agreement,
the terms and conditions of the Plan shall prevail.

         If designated in the Notice of Grant as an Incentive Stock Option
("ISO"), this Option is intended to qualify as an Incentive Stock Option under
Section 422 of the Code.  However, if this Option is intended to be an Incentive
Stock Option, to the extent that it exceeds the $100,000 rule of Code Section
422(d) it shall be treated as a Nonstatutory Stock Option ("NSO").

    2.   EXERCISE OF OPTION.

         (a)  RIGHT TO EXERCISE.  This Option is exercisable during its term in
accordance with the Vesting Schedule set out in the Notice of Grant and the
applicable provisions of the Plan and this Option Agreement.

         (b)  METHOD OF EXERCISE.  This Option is exercisable by delivery of an
exercise notice, in the form attached as Exhibit A (the "Exercise Notice"),
which shall state the election to exercise the Option, the number of Shares in
respect of which the Option is being exercised (the "Exercised Shares"), and
such other representations and agreements as may be required by the Company
pursuant to the provisions of the Plan.  The Exercise Notice shall be completed
by the Optionee and delivered to the Secretary of the Company.  The Exercise
Notice shall be accompanied by payment of the aggregate Exercise Price as to all
Exercised Shares.  This Option shall be deemed to be exercised upon receipt by
the Company of such fully executed Exercise Notice accompanied by such aggregate
Exercise Price.


<PAGE>

         No Shares shall be issued pursuant to the exercise of this Option
unless such issuance and exercise complies with Applicable Laws.  Assuming such
compliance, for income tax purposes the Exercised Shares shall be considered
transferred to the Optionee on the date the Option is exercised with respect to
such Exercised Shares.

    3.   METHOD OF PAYMENT.  Payment of the aggregate Exercise Price shall be
by any of the following, or a combination thereof, at the election of the
Optionee:

         (a)  cash;

         (b)  check;

         (c)  consideration received by the Company under a cashless exercise
program implemented  by the Company in connection with the Plan; or

         (d)  surrender of other Shares which (i) in the case of Shares
acquired upon exercise of an option, have been owned by the Optionee for more
than six (6) months on the date of surrender, AND (ii) have a Fair Market Value
on the date of surrender equal to the aggregate Exercise Price of the Exercised
Shares; or

         (e)  with the Administrator's consent, delivery of Optionee's
promissory note (the "Note") in the form attached hereto as Exhibit C, in the
amount of the aggregate Exercise Price of the Exercised Shares together with the
execution and delivery by the Optionee of the Security Agreement attached hereto
as Exhibit B.  The Note shall bear interest at the "applicable federal rate"
prescribed under the Code and its regulations at time of purchase, and shall be
secured by a pledge of the Shares purchased by the Note pursuant to the Security
Agreement.

    4.   NON-TRANSFERABILITY OF OPTION.  This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution and
may be exercised during the lifetime of Optionee only by the Optionee.  The
terms of the Plan and this Option Agreement shall be binding upon the executors,
administrators, heirs, successors and assigns of the Optionee.

    5.   TERM OF OPTION.  This Option may be exercised only within the term set
out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option Agreement.

    6.   TAX CONSEQUENCES.  Some of the federal tax consequences relating to
this Option, as of the date of this Option, are set forth below.  THIS SUMMARY
IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO
CHANGE.  THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION
OR DISPOSING OF THE SHARES.

         (a)  EXERCISING THE OPTION.

              (i)  NONSTATUTORY STOCK OPTION.  The Optionee may incur regular
federal income tax liability upon exercise of a NSO.  The Optionee will be
treated as having received compensation income (taxable at ordinary income tax
rates) equal to the excess, if any, of the Fair Market Value of the Exercised
Shares on the date of exercise over their aggregate Exercise Price.  If 

<PAGE>

the Optionee is an Employee or a former Employee, the Company will be required
to withhold from his or her compensation or collect from Optionee and pay to the
applicable taxing authorities an amount in cash equal to a percentage of this
compensation income at the time of exercise, and may refuse to honor the
exercise and refuse to deliver Shares if such withholding amounts are not
delivered at the time of exercise.

              (ii) INCENTIVE STOCK OPTION.  If this Option qualifies as an ISO,
the Optionee will have no regular federal income tax liability upon its
exercise, although the excess, if any, of the Fair Market Value of the Exercised
Shares on the date of exercise over their aggregate Exercise Price will be
treated as an adjustment to alternative minimum taxable income for federal tax
purposes and may subject the Optionee to alternative minimum tax in the year of
exercise.  In the event that the Optionee ceases to be an Employee but remains a
Service Provider, any Incentive Stock Option of the Optionee that remains
unexercised shall cease to qualify as an Incentive Stock Option and will be
treated for tax purposes as a Nonstatutory Stock Option on the date three (3)
months and one (1) day following such change of status.

              (b)  DISPOSITION OF SHARES. 

                   (i)  NSO.  If the Optionee holds NSO Shares for at least one
year, any gain realized on disposition of the Shares will be treated as long-
term capital gain for federal income tax purposes.

                   (ii) ISO.  If the Optionee holds ISO Shares for at least one
year after exercise  and two years after the grant date, any gain realized on
disposition of the Shares will be treated as long-term capital gain for federal
income tax purposes.  If the Optionee disposes of ISO Shares within one year
after exercise or two years after the grant date, any gain realized on such
disposition will be treated as compensation income (taxable at ordinary income
rates) to the extent of the excess, if any, of the lesser of (A) the difference
between the Fair Market Value of the Shares acquired on the date of exercise and
the aggregate Exercise Price, or (B) the difference between the sale price of
such Shares and the aggregate Exercise Price.  Any additional gain will be taxed
as capital gain, short-term or long-term depending on the period that the ISO
Shares were held.

              (c)  NOTICE OF DISQUALIFYING DISPOSITION OF ISO SHARES.  If the
Optionee sells or otherwise disposes of any of the Shares acquired pursuant to
an ISO on or before the later of (i) two years after the grant date, or (ii) one
year after the exercise date, the Optionee shall immediately notify the Company
in writing of such disposition.  The Optionee agrees that he or she may be
subject to income tax withholding by the Company on the compensation income
recognized from such early disposition of ISO Shares by payment in cash or out
of the current earnings paid to the Optionee.

    7.   ENTIRE AGREEMENT; GOVERNING LAW.  The Plan is incorporated herein by
reference.  The Plan and this Option Agreement constitute the entire agreement
of the parties with respect to the subject matter hereof and supersede in their
entirety all prior undertakings and agreements of the Company and Optionee with
respect to the subject matter hereof, and may not be modified adversely to the
Optionee's interest except by means of a writing signed by the Company and
Optionee.  This agreement is governed by the internal substantive laws, but not
the choice of law rules, of California.
    
<PAGE>

    8.   NO GUARANTEE OF CONTINUED SERVICE.  OPTIONEE ACKNOWLEDGES AND AGREES
THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED
ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (AND NOT
THROUGH THE ACT OF BEING HIRED, BEING GRANTED AN OPTION OR PURCHASING SHARES
HEREUNDER).  OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE
TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO
NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A
SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL
NOT INTERFERE WITH OPTIONEE'S RIGHT OR THE COMPANY'S RIGHT TO TERMINATE
OPTIONEE'S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT
CAUSE.

                                  SECURITY AGREEMENT



    This Security Agreement is made as of ______________, 19____ between
CardioThoracic Systems, Inc., a Delaware corporation ("Pledgee"), and
____________________________ ("Pledgor").


                                       RECITALS

    Pursuant to Pledgor's election to purchase Shares under the Option
Agreement dated _______________ (the "Option"), between Pledgor and Pledgee
under Pledgee's Incentive Stock Plan, and Pledgor's election under the terms of
the Option to pay for such shares with his promissory note (the "Note"), Pledgor
has purchased __________________ shares of Pledgee's Common Stock (the "Shares")
at a price of $ ____________ per share, for a total purchase price of $________.
The Note and the obligations thereunder are as set forth in Exhibit C to the
Option.

    NOW, THEREFORE, it is agreed as follows:

    1.   CREATION AND DESCRIPTION OF SECURITY INTEREST.  In consideration of
the transfer of the Shares to Pledgor under the Option Agreement, Pledgor,
pursuant to the California  Commercial Code, hereby pledges all of such Shares
(herein sometimes referred to as the "Collateral") represented by certificate
number ____________, duly endorsed in blank or with executed stock powers, and
herewith delivers said certificate to the Secretary of Pledgee ("Pledgeholder"),
who shall hold said certificate subject to the terms and conditions of this
Security Agreement.

    The pledged stock (together with an executed blank stock assignment for use
in transferring all or a portion of the Shares to Pledgee if, as and when
required pursuant to this Security Agreement) shall be held by the Pledgeholder
as security for the repayment of the Note, and any extensions or renewals
thereof, to be executed by Pledgor pursuant to the terms of the Option, and the
Pledgeholder shall not encumber or dispose of such Shares except in accordance
with the provisions of this Security Agreement.

    2.   PLEDGOR'S REPRESENTATIONS AND COVENANTS.  To induce Pledgee to enter
into this Security Agreement, Pledgor represents and covenants to Pledgee, its
successors and assigns, as follows:

         (a)  PAYMENT OF INDEBTEDNESS.  Pledgor will pay the principal sum of
the Note secured hereby, together with interest thereon, at the time and in the
manner provided in the Note.

         (b)  ENCUMBRANCES.  The Shares are free of all other encumbrances,
defenses and liens, and Pledgor will not further encumber the Shares without the
prior written consent of Pledgee.

         (c)  MARGIN REGULATIONS.  In the event that Pledgee's Common Stock is
now or later becomes margin-listed by the Federal Reserve Board and Pledgee is
classified as a "lender" within the meaning of the regulations under Part 207 of
Title 12 of the Code of Federal Regulations 


<PAGE>

("Regulation G"), Pledgor agrees to cooperate with Pledgee in making any
amendments to the Note or providing any additional collateral as may be
necessary to comply with such regulations.

    3.   VOTING RIGHTS.  During the term of this pledge and so long as all
payments of principal and interest are made as they become due under the terms
of the Note, Pledgor shall have the right to vote all of the Shares pledged
hereunder.

    4.   STOCK ADJUSTMENTS.  In the event that during the term of the pledge
any stock dividend, reclassification, readjustment or other changes are declared
or made in the capital structure of Pledgee, all new, substituted and additional
shares or other securities issued by reason of any such change shall be
delivered to and held by the Pledgee under the terms of this Security Agreement
in the same manner as the Shares originally pledged hereunder.  In the event of
substitution  of such securities, Pledgor, Pledgee and Pledgeholder shall
cooperate and execute such documents as are reasonable so as to provide for the
substitution of such Collateral and, upon such substitution, references to
"Shares" in this Security Agreement shall include the substituted shares of
capital stock of Pledgor as a result thereof.

    5.   OPTIONS AND RIGHTS.  In the event that, during the term of this
pledge, subscription Options or other rights or options shall be issued in
connection with the pledged Shares, such rights, Options and options shall be
the property of Pledgor and, if exercised by Pledgor, all new stock or other
securities so acquired by Pledgor as it relates to the pledged Shares then held
by Pledgeholder shall be immediately delivered to Pledgeholder, to be held under
the terms of this Security Agreement in the same manner as the Shares pledged.

    6.   DEFAULT.  Pledgor shall be deemed to be in default of the Note and of
this Security Agreement in the event:

         (a)  Payment of principal or interest on the Note shall be delinquent
for a period of 10 days or more; or

         (b)  Pledgor fails to perform any of the covenants set forth in the
Option or contained in this Security Agreement for a period of 10 days after
written notice thereof from Pledgee.

    In the case of an event of Default, as set forth above, Pledgee shall have
the right to accelerate payment of the Note upon notice to Pledgor, and Pledgee
shall thereafter be entitled to pursue its remedies under the California
Commercial Code.

    7.   RELEASE OF COLLATERAL.  Subject to any applicable contrary rules under
Regulation G, there shall be released from this pledge a portion of the pledged
Shares held by Pledgeholder hereunder upon payments of the principal of the
Note.  The number of the pledged Shares which shall be released shall be that
number of full Shares which bears the same proportion to the initial number of
Shares pledged hereunder as the payment of principal bears to the initial full
principal amount of the Note.

    8.   WITHDRAWAL OR SUBSTITUTION OF COLLATERAL.  Pledgor shall not sell,
withdraw, pledge, substitute or otherwise dispose of all or any part of the
Collateral without the prior written consent of Pledgee.

<PAGE>

    9.   TERM.  The within pledge of Shares shall continue until the payment of
all indebtedness secured hereby, at which time the remaining pledged stock shall
be promptly delivered to Pledgor, subject to the provisions for prior release of
a portion of the Collateral as provided in paragraph 7 above.

    10.  INSOLVENCY.  Pledgor agrees that if a bankruptcy or insolvency
proceeding is instituted by or against it, or if a receiver is appointed for the
property of Pledgor, or if Pledgor makes an assignment for the benefit of
creditors, the entire amount unpaid on the Note shall become immediately due and
payable, and Pledgee may proceed as provided in the case of default.

    11.  PLEDGEHOLDER LIABILITY.  In the absence of willful or gross
negligence, Pledgeholder shall not be liable to any party for any of his acts,
or omissions to act, as Pledgeholder.

    12.  INVALIDITY OF PARTICULAR PROVISIONS.  Pledgor and Pledgee agree that
the enforceability or invalidity of any provision or provisions of this Security
Agreement shall not render any other provision or provisions herein contained
unenforceable or invalid.

    13.  SUCCESSORS OR ASSIGNS.  Pledgor and Pledgee agree that all of the
terms of this Security Agreement shall be binding on their respective successors
and assigns, and that the term "Pledgor" and the term "Pledgee" as used herein
shall be deemed to include, for all purposes, the respective designees,
successors, assigns, heirs, executors and administrators.

    14.  GOVERNING LAW.  This Security Agreement shall be interpreted and
governed under  the internal substantive laws, but not the choice of law rules,
of California.

                                     EXHIBIT A-1

                                 INCENTIVE STOCK PLAN

                         RESTRICTED STOCK PURCHASE AGREEMENT

    Unless otherwise defined herein, the terms defined in the Plan shall have
the same defined meanings in this Restricted Stock Purchase Agreement.

    WHEREAS the Purchaser named in the Notice of Grant, (the "Purchaser") is a 
Service Provider, and the Purchaser's continued participation is considered by
the Company to be important for the Company's continued growth; and

    WHEREAS in order to give the Purchaser an opportunity to acquire an equity
interest in the Company as an incentive for the Purchaser to participate in the
affairs of the Company, the Administrator has granted to the Purchaser a Stock
Purchase Right subject to the terms and conditions of the Plan and the Notice of
Grant, which are incorporated herein by reference, and pursuant to this
Restricted Stock Purchase Agreement (the "Agreement").

    NOW THEREFORE, the parties agree as follows:

    1.   SALE OF STOCK.  The Company hereby agrees to sell to the Purchaser and
the Purchaser hereby agrees to purchase shares of the Company's Common Stock
(the "Shares"), at the per Share purchase price and as otherwise described in
the Notice of Grant.

    2.   PAYMENT OF PURCHASE PRICE.  The purchase price for the Shares may be
paid by delivery to the Company at the time of execution of this Agreement of
cash, a check, or some combination thereof.

    3.   REPURCHASE OPTION.

         (a)  In the event the Purchaser ceases to be a Service Provider for
any or no reason (including death or disability) before all of the Shares are
released from the Company's Repurchase Option (see Section 4), the Company
shall, upon the date of such termination (as reasonably fixed and determined by
the Company) have an irrevocable, exclusive option (the "Repurchase Option") for
a period of sixty (60) days from such date to repurchase up to that number of
shares which constitute the Unreleased Shares (as defined in Section 4) at the
original purchase price per share (the "Repurchase Price").  The Repurchase
Option shall be exercised by the Company by delivering written notice to the
Purchaser or the Purchaser's executor (with a copy to the Escrow Holder) AND, at
the Company's option, (i) by delivering to the Purchaser or the Purchaser's
executor a check in the amount of the aggregate Repurchase Price, or (ii) by
cancelling an amount of the Purchaser's indebtedness to the Company equal to the
aggregate Repurchase Price, or (iii) by a combination of (i) and (ii) so that
the combined payment and cancellation of indebtedness equals the aggregate
Repurchase Price.  Upon delivery of such notice and the payment of the aggregate
Repurchase Price, the Company shall become the legal and beneficial owner of the
Shares being repurchased and all rights and interests therein or relating
thereto, and the Company shall have the right to retain and transfer to its own
name the number of Shares being repurchased by the Company.

<PAGE>

         (b)  Whenever the Company shall have the right to repurchase Shares
hereunder, the Company may designate and assign one or more employees, officers,
directors or shareholders of the Company or other persons or organizations to
exercise all or a part of the Company's purchase rights under this Agreement and
purchase all or a part of such Shares.  If the Fair Market Value of the Shares
to be repurchased on the date of such designation or assignment (the "Repurchase
FMV") exceeds the aggregate Repurchase Price of such Shares, then each such
designee or assignee shall pay the Company cash equal to the difference between
the Repurchase FMV and the aggregate Repurchase Price of such Shares.

    4.   RELEASE OF SHARES FROM REPURCHASE OPTION.

         (a)  ___________________percent (_________%) of the Shares shall be
released from the  Company's Repurchase Option ___[ONE YEAR]___ after the Date
of Grant and ________________ percent (_______%) of the Shares [AT THE END OF
EACH MONTH THEREAFTER], provided that the Purchaser does not cease to be a
Service Provider prior to the date of any such release.

         (b)  Any of the Shares that have not yet been released from the
Repurchase Option are referred to herein as "Unreleased Shares."

         (c)  The Shares that have been released from the Repurchase Option
shall be delivered to the Purchaser at the Purchaser's request (see Section 6).

    5.   RESTRICTION ON TRANSFER.  Except for the escrow described in Section 6
or the transfer of the Shares to the Company or its assignees contemplated by
this Agreement, none of the Shares or any beneficial interest therein shall be
transferred, encumbered or otherwise disposed of in any way until such Shares
are released from the Company's Repurchase Option in accordance with the
provisions of this Agreement, other than by will or the laws of descent and
distribution.

    6.   ESCROW OF SHARES.

         (a)  To ensure the availability for delivery of the Purchaser's
Unreleased Shares upon repurchase by the Company pursuant to the Repurchase
Option, the Purchaser shall, upon execution of this Agreement, deliver and
deposit with an escrow holder designated by the Company (the "Escrow Holder")
the share certificates representing the Unreleased Shares, together with the
stock assignment duly endorsed in blank, attached hereto as Exhibit A-2.  The
Unreleased Shares and stock assignment shall be held by the Escrow Holder,
pursuant to the Joint Escrow Instructions of the Company and Purchaser attached
hereto as Exhibit A-3, until such time as the Company's Repurchase Option
expires.  As a further condition to the Company's obligations under this
Agreement, the Company may require the spouse of Purchaser, if any, to execute
and deliver to the Company the Consent of Spouse attached hereto as Exhibit A-4.
              
         (b)  The Escrow Holder shall not be liable for any act it may do or
omit to do with respect to holding the Unreleased Shares in escrow while acting
in good faith and in the exercise of its judgment.

         (c)  If the Company or any assignee exercises the Repurchase Option
hereunder, the Escrow Holder, upon receipt of written notice of such exercise
from the proposed transferee, shall take all steps necessary to accomplish such
transfer.

<PAGE>

         (d)  When the Repurchase Option has been exercised or expires
unexercised or a portion of the Shares has been released from the Repurchase
Option, upon request the Escrow Holder shall promptly cause a new certificate to
be issued for the released Shares and shall deliver the certificate to the
Company or the Purchaser, as the case may be.

         (e)  Subject to the terms hereof, the Purchaser shall have all the
rights of a shareholder with respect to the Shares while they are held in
escrow, including without limitation, the right to vote the Shares and to
receive any cash dividends declared thereon.  If, from time to time during the
term of the Repurchase Option, there is (i) any stock dividend, stock split or
other change in the Shares, or (ii) any merger or sale of all or substantially
all of the assets or other acquisition of the Company, any and all new,
substituted or additional securities to which the Purchaser is entitled by
reason of the Purchaser's ownership of the Shares shall be immediately subject
to this escrow, deposited with the Escrow Holder and included thereafter as
"Shares" for purposes of this Agreement and the Repurchase Option.

    7.   LEGENDS.  The share certificate evidencing the Shares, if any,  issued
hereunder shall be endorsed with the following legend (in addition to any legend
required under applicable state securities laws):

    THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
RESTRICTIONS UPON TRANSFER AND RIGHTS OF REPURCHASE AS SET FORTH IN AN AGREEMENT
BETWEEN THE COMPANY AND THE SHAREHOLDER, A COPY OF  WHICH IS ON FILE WITH THE
SECRETARY OF THE COMPANY.

    8.   ADJUSTMENT FOR STOCK SPLIT.  All references to the number of Shares
and the purchase price of the Shares in this Agreement shall be appropriately
adjusted to reflect any stock split, stock dividend or other change in the
Shares which may be made by the Company after the date of this Agreement.

    9.   TAX CONSEQUENCES.  The Purchaser has reviewed with the Purchaser's own
tax advisors the federal, state, local and foreign tax consequences of this
investment and the transactions contemplated by this Agreement.  The Purchaser
is relying solely on such advisors and not on any statements or representations
of the Company or any of its agents.  The Purchaser understands that the
Purchaser (and not the Company) shall be responsible for the Purchaser's own tax
liability that may arise as a result of the transactions contemplated by this
Agreement.  The Purchaser understands that Section 83 of the Internal Revenue
Code of 1986, as amended (the "Code"), taxes as ordinary income the difference
between the purchase price for the Shares and the Fair Market Value of the
Shares as of the date any restrictions on the Shares lapse.  In this context,
"restriction" includes the right of the Company to buy back the Shares pursuant
to the Repurchase Option.  The Purchaser understands that the Purchaser may
elect to be taxed at the time the Shares are purchased rather than when and as
the Repurchase Option expires by filing an election under Section 83(b) of the
Code with the IRS within 30 days from the date of purchase.  The form for making
this election is attached as Exhibit A-5 hereto.

         THE PURCHASER ACKNOWLEDGES THAT IT IS THE PURCHASER'S SOLE
RESPONSIBILITY AND NOT THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER

<PAGE>

SECTION 83(b), EVEN IF THE PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVES
TO MAKE THIS FILING ON THE PURCHASER'S BEHALF.

    10.  GENERAL PROVISIONS.

         (a)  This Agreement shall be governed by the internal substantive
laws, but not the choice of law rules of California.  This Agreement, subject to
the terms and conditions of the Plan and the Notice of Grant, represents the
entire agreement between the parties with respect to the purchase of the Shares
by the Purchaser.  Subject to Section 15(c) of the Plan, in the event of a
conflict between the terms and conditions of the Plan and the terms and
conditions of this Agreement, the terms and conditions of the Plan shall
prevail.  Unless otherwise defined herein, the terms defined in the Plan shall
have the same defined meanings in this Agreement.

         (b)  Any notice, demand or request required or permitted to be given
by either the Company or the Purchaser pursuant to the terms of this Agreement
shall be in writing and shall be deemed given when delivered personally or
deposited in the U.S. mail, First Class with postage prepaid, and addressed to
the parties at the addresses of the parties set forth at the end of this
Agreement or such other address as a party may request by notifying the other in
writing.

         Any notice to the Escrow Holder shall be sent to the Company's address
with a copy to the other party hereto.

         (c)  The rights of the Company under this Agreement shall be
transferable to any one or more persons or entities, and all covenants and
agreements hereunder shall inure to the benefit of, and be enforceable by the
Company's successors and assigns.  The rights and obligations of the Purchaser
under this Agreement may only be assigned with the prior written consent of the
Company.

         (d)  Either party's failure to enforce any provision of this Agreement
shall not in any way be construed as a waiver of any such provision, nor prevent
that party from thereafter enforcing any other provision of this Agreement.  The
rights granted both parties hereunder are cumulative and shall not constitute a
waiver of either party's right to assert any other legal remedy available to it.
              
         (e)  The Purchaser agrees upon request to execute any further
documents or instruments necessary or desirable to carry out the purposes or
intent of this Agreement.

         (f)  PURCHASER ACKNOWLEDGES AND AGREES THAT THE VESTING OF  SHARES
PURSUANT TO SECTION 4 HEREOF IS EARNED ONLY BY CONTINUING SERVICE AS A SERVICE
PROVIDER AT THE WILL OF THE COMPANY (AND NOT THROUGH THE ACT OF BEING HIRED OR
PURCHASING SHARES HEREUNDER).  PURCHASER FURTHER ACKNOWLEDGES AND AGREES THAT
THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE
SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED
ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT
ALL, AND SHALL NOT INTERFERE WITH PURCHASER'S RIGHT OR THE COMPANY'S RIGHT TO
TERMINATE PURCHASER'S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR
WITHOUT CAUSE.

documents delivered to you pursuant to the terms of that certain Restricted
Stock Purchase Agreement ("Agreement") between the Company and the undersigned,
in accordance with the following instructions:

    1.   In the event the Company and/or any assignee of the Company (referred

necessary for the transfer in question, (b) to fill in the number of shares

    3.   Purchaser irrevocably authorizes the Company to deposit with you any

Repurchase Option.

given by any of the parties hereto or by any other person or corporation,

not be liable to any of the parties hereto or to any other person, firm or
corporation by reason of such compliance, notwithstanding any such order,
judgment or decree being subsequently reversed, modified, annulled, set aside,
vacated or found to have been entered without jurisdiction.

authorities or rights of the parties executing or delivering or purporting to
execute or deliver the Agreement or any documents or papers deposited or called
for hereunder.

with these Joint Escrow Instructions or obligations in respect hereto, the

to the delivery and/or ownership or right of possession of the securities held
by you hereunder, you are authorized 

<PAGE>

and directed to retain in your possession without liability to anyone all or any
part of said securities until such disputes shall have been settled either by
mutual written agreement of the parties concerned or by a final order, decree or
judgment of a court of competent jurisdiction after the time for appeal has
expired and no appeal has been perfected, but you shall be under no duty
whatsoever to institute or defend any such proceedings.

SUCH SALE OR DISPOSITION MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION
STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY

(the "Company"), hereby grants to ____________________ (the "Optionee") an
Option to purchase a total of _____________ shares of Common Stock (the
"Shares") at _______ per share under the Company's Nonstatutory Option Plan.
This Option is intended by the Company and the Optionee to be a Nonstatutory
Stock Option, and does not qualify for any special tax benefits to the Optionee.

    2.   EXERCISE OF OPTION.  This Option shall be exercisable during its term
as follows:

         (i)  RIGHT TO EXERCISE

              (a)  Subject to subsections 3(i)(b), (c) and (d) below, ________.

              (b)  This Option may not be exercised for a fraction of a Share.

              (c)  In the event of Optionee's death, disability or other
termination of employment, the exercisability of the Option is governed by
Sections 6, 7 and 8 below, subject to the limitations contained in
subsection 2(i)(d).

              (d) In no event may this Option be exercised after the date of
expiration of the term of this Option as set forth in Section 10 below.

       (ii)   METHOD OF EXERCISE.  This Option shall be exercisable by written
notice which shall state the election to exercise the Option, the number of
Shares in respect of which the Option is being exercised, and such other
representations and agreements as to the holder's investment intent with respect
to such shares of Common Stock as may be required by the Company.  Such written
notice shall be signed by Optionee and shall be delivered in person or by
certified mail to the President, Secretary or Chief Financial Officer of the
Company.  The written notice shall be accompanied by payment of the exercise
price.  The Option shall be deemed exercised upon receipt by the Company of such
written notice accompanied by the exercise price.

         No shares will be issued pursuant to the exercise of an Option unless
such issuance and such exercise shall comply with all relevant provisions of law
and the requirements of any stock exchange upon which the Shares may then be
listed.  Assuming such compliance, for income tax


<PAGE>

purposes the Shares shall be considered transferred to the Optionee on the date
on which the Option is exercised with respect to such Shares.

    3. INVESTMENT REPRESENTATIONS; RESTRICTIONS ON TRANSFER.

         (i)  By receipt of this Option, by its execution and by its exercise
in whole or in part, Optionee represents to the Company the following:

              (a)  Optionee understands that this Option and any Shares
purchased upon its exercise are securities, the issuance of which requires
compliance with federal and state securities laws.

              (b)  Optionee is aware of the Company's business affairs and
financial condition and has acquired sufficient information about the Company to
reach an informed and knowledgeable decision to acquire the securities.
Optionee is acquiring these securities for investment only and not with a view
to, or for resale in connection with, any "distribution" thereof within the
meaning of the Securities Act of 1933, as amended (the "Securities Act").

              (c)  Optionee acknowledges and understands that the securities
constitute "restricted securities" under the Securities Act and must be held
indefinitely unless they are subsequently registered under the Securities Act or
an exemption from such registration is available.  Optionee further acknowledges
and understands that the Company is under no obligation to register the
securities.  Optionee understands that the certificate evidencing the securities
will be imprinted with a legend which prohibits the transfer of the securities
unless they are registered or such registration is not required in the opinion
of counsel satisfactory to the Company any other legend required under
applicable state securities laws.

              (d)  Optionee is familiar with the provisions of Rule 701 and
Rule 144, each promulgated under the Securities Act, which, in substance, permit
limited public resale of "restricted securities" acquired, directly or
indirectly, from the issuer thereof, in a non-public offering subject to the
satisfaction of certain conditions.  Rule 701 provides that if the issuer
qualifies under Rule 701 at the time of exercise of the Option by the Optionee,
such exercise will be exempt from registration under the Securities Act.  In the
event the Company later becomes subject to the reporting requirements of
Section 13 or 15(d) of the Securities Exchange Act of 1934, ninety (90) days
thereafter the securities exempt under Rule 701 may be resold, subject to the
satisfaction of certain of the conditions specified by Rule 144, including among
other things:  (1) the sale being made through a broker in an unsolicited
"broker's transaction" or in transactions directly with a market maker (as said
term is defined under the Securities Exchange Act of 1934); and, in the case of
an affiliate, (2) the availability of certain public information about the
Company, and the amount of securities being sold during any three month period
not exceeding the limitations specified in Rule 144(e), if applicable.
Notwithstanding this paragraph 4(i)(d), the Optionee acknowledges and agrees to
the restrictions set forth in paragraph 4(ii).


                                         -2-

<PAGE>

         In the event that the Company does not qualify under Rule 701 at the
time of exercise of the Option, then the securities may be resold in certain
limited circumstances subject to the provisions of Rule 144, which requires
among other things:  (1) the availability of certain public information about
the Company:  (2) the resale occurring not less than two years after the party
has purchased, and made full payment for, within the meaning of Rule 144, the
securities to be sold; and (3) in the case of an affiliate, or of a
non-affiliate who has held the securities less than three years, the sale being
made through a broker in an unsolicited "broker's transaction" or in
transactions directly with a market maker (as that term is defined under the
Securities Exchange Act of 1934) and the amount of securities being sold during
any three month period not exceeding the specified limitations stated therein,
if applicable.

       (ii)   Optionee agrees, in connection with the initial underwritten
public offering of the Company's securities, (1) not to sell, make short sale
of, loan, grant any options for the purchase of, or otherwise dispose of any
shares of Common Stock of the Company held by Optionee (other than those shares
included in the registration) without the prior written consent of the Company
or the underwriters managing such initial underwritten public offering of the
Company's securities for one hundred eighty (180) days from the effective date
of such registration, and (2) further agrees to execute any agreement reflecting
(1) above as may be requested by the underwriters at the time of the public
offering.

    4.   METHOD OF PAYMENT.  Payment of the purchase price shall be made by
cash or check.

    5.   RESTRICTIONS ON EXERCISE.  This Option may not be exercised if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations (Regulation G) as
promulgated by the Federal Reserve Board.  As a condition to the exercise of
this Option, the Company may require Optionee to make any representation and
warranty to the Company as may be required by any applicable law or regulation.

    6.   TERMINATION OF EMPLOYMENT RELATIONSHIP.  In the event of termination
of Optionee's employment with or services to the Company, Optionee may, but only
within thirty (30) days after the date of such termination (but in no event
later than the date of expiration of the term of this Option as set forth in
Section 10 below), exercise this Option to the extent that Optionee was entitled
to exercise it at the date of such termination.  To the extent that Optionee was
not entitled to exercise this Option at the date of such termination, or if
Optionee does not exercise this Option within the time specified herein, this
Option shall terminate.

    7.   DISABILITY OF OPTIONEE.  Notwithstanding the provisions of Section 6
above, in the event of termination of Optionee's employment with or services to
as a result of Optionee's permanent and total disability (as defined in
Section 22(e)(3) of the Internal Revenue Code of 1986, as amended), Optionee
may, but only within six (6) months from the date of such termination (but in no
event later than the date of expiration of the term of this Option as set forth
in Section 10 below),


                                         -3-

<PAGE>

exercise this Option to the extent Optionee was entitled to exercise it at the
date of such termination.  To the extent that Optionee was not entitled to
exercise this Option at the date of termination, or if Optionee does not
exercise such Option (which Optionee was entitled to exercise) within the time
specified herein, this Option shall terminate.

    8.   DEATH OF OPTIONEE.  In the event of the death of Optionee:

         (i)  during the term of this Option while employed by or providing
services to the Company, this Option may be exercised, at any time within six
(6) months following the date of death (but in no event later than the date of
expiration of the term of this Option as set forth in Section 10 below), by
Optionee's estate or by a person who acquired the right to exercise the Option
by bequest or inheritance, but only to the extent that Optionee was entitled to
exercise this Option at the date of death; or

       (ii)   within thirty (30) days after the termination of Optionee's
employment with or services to the Company, this Option may be exercised, at any
time within six (6) months following the date of death (but in no event later
than the date of expiration of the term of this Option as set forth in
Section 10 below), by Optionee's estate or by a person who acquired the right to
exercise this Option by bequest or inheritance, but only to the extent of the
right to exercise that had accrued at the date of termination.

    9.   NON-TRANSFERABILITY OF OPTION.  This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution and
may be exercised during the lifetime of Optionee only by Optionee.  The terms of
this Option shall be binding upon the executors, administrators, heirs,
successors and assigns of Optionee.

    10.  TERM OF OPTION.  This Option will expire on ____________ and
accordingly may not be exercised after such date.

    11.  TAX CONSEQUENCES.  Optionee has reviewed with Optionee's own tax
advisors the federal, state, local and foreign tax consequences of the
transactions contemplated by this Agreement.  Optionee is relying solely on such
advisors and not on any statements or representations of the Company or any of
its agents.  Optionee understands that Optionee (and not the Company) shall be


                                         -4-

<PAGE>

responsible for Optionee's own tax liability that may arise as a result of the

                      MANAGEMENT'S DISCUSSION AND ANALYSIS OF 
                   FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                           CardioThoracic Systems, Inc.

The following discussion of the financial condition and results of operations 
of CardioThoracic Systems, Inc. ("CTS" or the "Company") should be read in 
conjunction with the Consolidated Financial Statements and the related Notes 
thereto included herein.
     This report contains forward looking statements within the meaning of 
Section 27A of the Securities Act of 1933 and Section 21E of the Securities 
and Exchange Act of 1934. The Company's future results of operations could 
vary significantly from those anticipated by such statements as a result of 
factors described in the Management's Discussion and Analysis of Financial 
Condition and Results of Operations and under "Factors Affecting Results of 
Operations".

OVERVIEW 
     The business of the Company was commenced in November 1993 as a sole 
proprietorship, Informed Creation, and to date the business has been engaged 
primarily in organizational, research, product development and 
commercialization efforts. In June 1995, the business was incorporated and as 
part of the Company's initial financing in September 1995, the Company 
acquired all intellectual property assets of Informed Creation. The Company 
has a limited operating history upon which evaluation of its prospects can be 
made. Such prospects must be considered in light of the substantial risks, 
expenses and difficulties encountered by entrants into the medical device 
industry, which is characterized by an increasing number of participants, 
intense competition and a high failure rate. The Company has only recently 
generated revenues and has very limited experience in manufacturing, 
marketing or selling the CTS MIDCAB-TM- System. The Company has experienced 
operating losses since its inception, and, as of December 31, 1996, the 
Company had an accumulated deficit of approximately $17,075,000. The 
development and commercialization of the Company's products will require 
substantial development, regulatory, sales and marketing, manufacturing and 
other expenditures. The Company expects its operating losses to continue at 
least through 1997 as it expends substantial resources to continue 
development of the Company's products, obtain additional regulatory 
clearances or approvals, build its marketing, sales, manufacturing and 
finance organizations and conduct further research and development. There can 
be no assurance that the Company's products will ever gain wide spread 
commercial acceptance or that the Company will ever generate enough revenues 
to achieve profitability.
     The CTS MIDCAB System is designed to enable the majority of 
cardiothoracic surgeons to perform the MIDCAB procedure. Accordingly, the 
Company's success is dependent upon acceptance of the MIDCAB procedure by the 
medical community as a reliable, safe and cost effective alternative to 
existing treatments for revascularizing blocked coronary arteries. To date, 
the MIDCAB procedure has only been performed on a limited basis by a small 
number of highly skilled cardiothoracic surgeons. Of the procedures performed 
to date, the vast majority have been performed on a single artery, typically 
the left anterior descending artery ("LAD") or, in substantially fewer 
instances, the right coronary artery ("RCA"), and an extremely limited number 
have been performed on the circumflex artery. Currently, a significant 
percentage of CABG procedures are performed on multiple vessels. To date, 
multiple vessel MIDCAB procedures have only been performed on an extremely 
limited basis, and there can be no assurance that the MIDCAB procedure will 
be effectively utilized for multiple bypasses on a more frequent basis. The 
Company is unable to predict how quickly, if at all, the MIDCAB procedure 
will be adopted by the medical community or, if it is adopted, the number of 
MIDCAB procedures that will be performed. The medical conditions that can be 
treated with the MIDCAB procedure can also be treated by widely accepted 
surgical procedures such as CABG surgery and catheter-based treatments, 
including balloon angioplasty, atherectomy and coronary stenting. Although 
the Company believes that the MIDCAB procedure has significant advantages 
over competing procedures, broad-based clinical adoption of the MIDCAB 
procedure will not occur until physicians determine that the procedure is an 
attractive alternative to current treatments for coronary artery disease. The 
Company believes that physician endorsements will be essential for clinical 
adoption of this procedure, and there can be no assurance that any such 
endorsements will be obtained in a timely manner, if at all. Clinical 
adoption will also depend upon the Company's ability to facilitate training 
of cardiothoracic surgeons to perform minimally invasive bypass surgery on a 
beating heart, and the willingness of such surgeons to perform such a 
procedure. Patient acceptance of the procedure will depend in part upon 
physician recommendations as well as other factors, including the degree of 
invasiveness, the effectiveness of the procedure and rate and severity of 
complications associated with the procedure as compared to other treatments. 
Even if the clinical efficacy of the MIDCAB procedure is established, 
physicians may elect not to recommend the procedure unless acceptable 
reimbursement from health care payors is available. Health care payor 
acceptance may require evidence of the cost effectiveness of the MIDCAB 
procedure as compared to other currently available treatments. There can be 
no assurance that the MIDCAB procedure will gain clinical adoption. Failure 
of the MIDCAB procedure to achieve significant clinical adoption would have a 
material adverse effect on the Company's business, financial condition and 
results of operations.
     The CTS MIDCAB System is the Company's primary near-term product focus 
and is expected to account for the great majority of the Company's revenues 
for the foreseeable future. The CTS MIDCAB System is in the early stage of 
commercialization. The Company has manufactured and sold a very small number 
of systems, and there can be no assurance that the Company is capable of 
manufacturing the CTS MIDCAB System in commercial quantities at acceptable 
costs. Nor can there be any assurance that demand for the CTS MIDCAB System 
will be sufficient to allow profitable operations. Failure of the CTS MIDCAB 
System to be successfully commercialized would have a material adverse effect 
on the Company's business, financial condition and results of operations. 
     Before the Company can market additional products in the United States, 
the Company must obtain clearance or approval from the FDA. The Company has 
filed a 510(k) premarket 

<PAGE>

notification with the FDA for clearance to market additional components of 
the CTS MIDCAB System and Saphenous Vein Harvesting System. There can be no 
assurance that the FDA will act favorably or quickly on the Company's 510(k) 
submissions, or that significant difficulties and costs will not be 
encountered by the Company in its efforts to obtain FDA clearance. Any such 
difficulties could delay or preclude obtaining regulatory clearance or 
approval. In addition, there can be no assurance that the FDA will not impose 
strict labeling or other requirements as a condition of its 510(k) clearance, 
any of which could limit the Company's ability to market additional products. 
Further, if the Company wishes to modify a product after FDA clearance of a 
510(k) premarket notification or approval of a PMA, including changes in 
indications or other modifications that could affect safety and efficacy, 
additional clearances or approvals will be required from the FDA. Failure to 
receive, or delays in receipt of, FDA clearances or approvals, including 
delays resulting from an FDA request for clinical trials or additional data 
as a prerequisite to clearance or approval, or any FDA conditions that limit 
the ability of the Company to market its products under development, could 
have a material adverse effect on the Company's business, financial condition 
and results of operations. 
     In order for the Company to market its products under development in 
Europe and certain other international jurisdictions, the Company and its 
distributors and agents must obtain required regulatory registrations or 
approvals and otherwise comply with extensive regulations regarding safety, 
efficacy and quality. These regulations, including the requirements for 
registrations or approvals and the time required for regulatory review, vary 
from country to country. The Company has received ISO 9001 and the CE Mark 
approval for use of its CTS MIDCAB System. The CE Mark provides the 
regulatory approval necessary for commercialization in European Union 
countries and eliminates having to obtain individual country approvals. There 
can be no assurance that the Company will obtain future regulatory 
registrations or approvals in other such countries or that it will not be 
required to incur significant costs in obtaining or maintaining its foreign 
regulatory registrations or approvals. Delays in receipt of these 
registrations or approvals to market its products under development, failure 
to receive these clearances or approvals, or future loss of previously 
received registrations or approvals could have a material adverse effect on 
the Company's business, financial condition and results of operations.

RESULTS OF OPERATIONS

CARDIOTHORACIC SYSTEMS, INC. FOR THE YEAR ENDED DECEMBER 31, 1996 COMPARED TO 
THE COMBINED YEAR ENDED DECEMBER 31, 1995.
Revenues were $141,000 in the year ended December 31, 1996 compared to no 
revenues in the year ended December 31, 1995. The Company held its first COR 
training and commenced shipments of the CTS MIDCAB System in December 1996.
     The research and development expenses for the year ended December 31, 
1996 were $11,475,000 compared to $491,000 for the year ended December 31, 
1995. This increase was due in part to a $5,322,000 charge for amortization 
of deferred compensation in the year ended December 31, 1996, compared with a 
$132,000 charge in 1995. The remaining increase was due to an increase in 
research and development staff and increased expenditures related to the 
continuing development of the instruments associated with the CTS MIDCAB 
System and Saphenous Vein Harvesting System. The Company 


                                      15
<PAGE>

expects that research and development expenses will continue to increase in 
1997 as the Company expands its research and development activities related 
to the CTS MIDCAB System, Saphenous Vein Harvesting System, valve repair and 
replacement and other research efforts. This increase in costs will be offset 
somewhat by a significant decrease in amortization of deferred compensation 
in 1997.
     Sales, marketing, general and administrative expenses increased to 
$6,977,000 for the year ended December 31, 1996 compared to $561,000 for the 
year ended December 31, 1995. This increase was due in part to a $1,410,000 
charge for amortization of deferred compensation in the year ended December 
31, 1996, compared with a $128,000 charge in 1995. The remaining increase was 
due primarily to the hiring of marketing and administrative personnel and 
consultants, the Company's promotional efforts to increase market awareness 
of the Company and the CTS MIDCAB procedure and establishing the Company's 
administrative infrastructure. The Company expects that sales and marketing 
and administrative expenses will continue to increase substantially in 1997 
as the Company builds its sales and marketing and administrative 
organizations, establishes a direct sales force in Germany, sponsors CTS COR 
surgeon training programs, puts in place financial and management information 
and control systems, and makes expenditures to increase market awareness of 
the CTS MIDCAB procedure and the CTS MIDCAB System.
     The Company has recorded deferred compensation of $12,734,000 for the 
difference between the option exercise price or restricted stock purchase 
price and the deemed fair value of the Company's Common Stock for options 
granted and restricted stock sold in 1995 and early 1996. The deferred 
compensation is being amortized to operating expenses over the related 
vesting period of the shares (one to four years) and will, therefore, 
continue to have an adverse effect on the Company's results of operations. 
Amortization of deferred compensation charged to operating expenses in the 
year ended December 31, 1996 totaled $6,732,000.
     Interest income increased to $3,103,000 for the year ended December 31, 
1996 compared to $47,000 for the year ended December 31, 1995. The increase 
was primarily due to the interest received on higher average cash balances 
resulting from the completion of the Company's initial public offering in 
April 1996 as described in note 1 of the CardioThoracic Systems, Inc. Notes 
to Consolidated Financial Statements.
     Interest expense increased to $27,000 for 1996 compared to no expense in 
1995. This increase is due to debt acquired during 1996 under an equipment 
loan credit facility and a bank line of credit.

COMBINED YEAR ENDED DECEMBER 31, 1995 COMPARED TO INFORMED CREATION FOR THE YEAR
ENDED DECEMBER 31, 1994.
The combined research and development expenses for the year ended December 
31, 1995 were $491,000 compared to $20,000 for the year ended December 31, 
1994. This increase was due to an increase in research and development staff, 
increased expenditures related to the continuing development of the 
instruments associated with the CTS MIDCAB System and amortization of 
deferred compensation incurred in 1995.
     Sales, marketing, general and administration expenses increased to 
$561,000 for the combined year ended December 31, 1995 from $22,000 for the 
year ended December 31, 1994. This increase was due primarily to the hiring 
of marketing and administration personnel and consultants, establishing the 
Company's administration infrastructure, the Company's promotional efforts to 
increase market awareness of the Company and the MIDCAB procedure and 
amortization of deferred compensation incurred in 1995.
     Interest income increased to $47,000 for the combined year ended 
December 31, 1995 from $63 for the year ended December 31, 1994. The increase 
was primarily due to the interest received on higher average cash balances 
resulting from a private equity financing that closed in September 1995.

LIQUIDITY AND CAPITAL RESOURCES
Since inception, the Company has financed operations primarily from the sale 
of equity securities. As of December 31, 1996, the Company had raised 
approximately $89,319,000 (net of stock issuance costs) from the sale of 
equity securities. As of December 31, 1996, cash, cash equivalents and 
available-for-sale securities totaled $78,457,000. The Company's cash used in 
operations was $7,444,000 for the year ended December 31, 1996, reflecting 
expenditures made primarily to increase research and development, to commence 
marketing and sales activities and to support its administrative 
infrastructure. The Company also spent $2,681,000 for the purchases of 
property and equipment, the majority of which was related to leasehold 
improvements and equipment required for the new facility the Company occupied 
in August 1996. The Company also provided loans to certain officers totaling 
$1,340,000 of which $68,333 has been amortized in 1996 (as described in note 
10 of the Company's Notes to the Consolidated Financial Statements).
     The Company sold 5,117,500 shares of common stock (including 667,500 
shares from the exercise of the underwriter's over-allotment option) at 
$18.00 per share through an initial public offering in April 1996. Net 
proceeds (after underwriter's commissions and fees along with other costs 
associated with the offering) totaled approximately $84,223,000.
     The Company plans to finance its operations principally from existing 
cash, cash equivalents and available-for-sale securities and interest 
thereon, product revenues and, to the extent available, lines of credit. The 
Company currently has an agreement with a bank for a $3,500,000 million line 
of credit, fully secured by cash, cash equivalents and available-for-sale 
securities, of which $3,075,000 is available at December 31, 1996. The 
Company also has a $2,500,000 equipment loan credit facility available to 
finance the purchase of certain equipment, of which $1,662,000 is available 
at December 31, 1996. The Company believes that the Company's existing cash 
balances and available-for-sale securities and the interest thereon, credit 
lines and product revenues will be sufficient to fund its operations through 
1998. The Company's capital requirements depend on numerous factors, 
including the progress of the Company's product 


                                      16
<PAGE>

development programs, the receipt of and the time required to obtain 
regulatory clearances or approvals, the resources the Company devotes to 
developing, manufacturing and marketing its products, the extent to which the 
Company's products receive market acceptance, and other factors. The Company 
expects to devote substantial capital resources to research and development, 
to hire and develop a direct sales force in the United States and Germany and 
to expand manufacturing capacity and facilities. The timing and amount of 
such capital requirements cannot be accurately predicted. Consequently, the 
Company may be required to raise additional funds through public or private 
financing, collaborative relationships or other arrangements. There can be no 
assurance that the Company will not require additional funding or that such 
additional funding, if needed, will be available on terms attractive to the 
Company, or at all, which could have a material adverse effect on the 
Company's business, financial condition and results of operations. Any 
additional equity financing may be dilutive to stockholders, and debt 
financing, if available, may involve restrictive covenants.
     At December 31, 1996, the Company had approximately $7,260,000 in 
federal and state net operating loss carryforwards, which expire in the years 
2011 and 2001, respectively. Utilization of federal income tax carryforwards 
is subject to certain limitations under Section 382 of the Internal Revenue 
Code of 1986. These annual limitations may result in expiration of net 
operating losses and research and development credits before they can be 
fully utilized.

FACTORS AFFECTING RESULTS OF OPERATIONS

CONTINUING GOVERNMENT REGULATION.
Regulatory clearances or approvals, if granted, may include significant 
limitations on the indicated uses for which the products may be marketed. FDA 
enforcement policy strictly prohibits the marketing of FDA cleared or 
approved medical devices for unapproved uses. In addition, the Company's 
manufacturing processes will be required to comply with the Good 
Manufacturing Practices ("GMP") regulations of the FDA. These regulations 
include design, testing, production, control, documentation and other 
requirements. Enforcement of GMP regulations has increased significantly in 
the last several years, and the FDA has publicly stated that compliance will 
be more strictly scrutinized. The Company's facilities and manufacturing 
processes, as well as those of any future third-party suppliers, will be 
subject to periodic inspection by the FDA, the California Department of 
Health Services and other agencies. To date, the Company has only undergone 
inspection for ISO 9001 certification. Failure to comply with these and other 
applicable regulatory requirements could result in, among other things, 
warning letters, fines, injunctions, civil penalties, recall or seizure of 
products, total or partial suspension of production, refusal of the 
government to grant premarket clearance or premarket approval for devices, 
withdrawal of clearances or approvals and criminal prosecution, which could 
have a material adverse effect on the Company's business, financial condition 
and results of operations.

HIGHLY COMPETITIVE MARKET; RISK OF ALTERNATIVE THERAPIES; RISK OF REUSE. 
The medical device industry and the market for treatment of cardiovascular 
disease, in particular, are characterized by rapidly evolving technology and 
intense competition. A number of competitors, including Johnson & Johnson, 
Boston Scientific Corporation, Cordis Corporation, Guidant Corporation and 
Medtronic, Inc., are currently marketing stents, catheters, lasers, drugs and 
other less invasive means of treating cardiovascular disease. Many of these 
less invasive treatments and CABG surgery are widely accepted in the medical 
community and have a long history of safe and effective use. Many of the 
Company's competitors have substantially greater capital resources, name 
recognition and expertise in and resources devoted to research and 
development, manufacturing and marketing and obtaining regulatory clearances 
or approvals. Furthermore, competition in the emerging market for minimally 
invasive cardiothoracic surgery is expected to be intense and to increase. 
Heartport, Inc., Medtronic, Inc., Research Medical Inc. and United States 
Surgical Corp. are marketing or have announced that they are developing 
products to be used in minimally invasive coronary procedures. There can be 
no assurance that the MIDCAB procedure will replace any current treatments. 
Additionally, even if it is widely adopted, there can be no assurance that 
the Company's competitors will not succeed in developing or marketing 
alternative procedures and technologies or competing devices to perform the 
same procedure or therapeutic drugs that are more effective than the 
Company's products or that render the Company's products or technologies 
obsolete or not competitive. In addition, there can be no assurance that 
existing products for other surgical uses will not be used in MIDCAB 
procedures. Furthermore, sales of the CTS MIDCAB System could be adversely 
affected by reuse of the Company's products, notwithstanding the instructions 
in the Company's clinical protocols and product labeling indicating that each 
of the components of the CTS MIDCAB System is a single-use device. Such 
competition or reuse could have a material adverse effect on the Company's 
business, financial condition and results of operations.

DEPENDENCE ON LICENSES, PATENTS AND PROPRIETARY TECHNOLOGY. 
The Company's ability to compete effectively will depend in part on its 
ability to develop and maintain proprietary aspects of its technology. The 
Company owns two issued United States patents. The issued patents do not 
contain any claims that protect the CTS MIDCAB System. The Company is the 
licensee of a United States patent application for bipolar electrosurgical 
scissors that are used in the Saphenous Vein Harvesting System. The Company 
has filed twenty-one patent applications. There can be no assurance that any 
issued patents or any patents which may be issued as a result of the 
Company's licensed patent application or United States and international 
patent applications will provide any competitive advantages for the Company's 
products or that they will not be successfully challenged, invalidated or 
circumvented in the future. In addition, there can be no assurance that 
competitors, many of which have substantial resources and have made 
substantial investments in competing technologies, will not seek to apply for 
and 


                                      17
<PAGE>

obtain patents that will prevent, limit or interfere with the Company's 
ability to make, use and sell its products either in the United States or in 
international markets.
      The medical device industry has been characterized by extensive 
litigation regarding patents and other intellectual property rights, and 
companies in the medical device industry have employed intellectual property 
litigation to gain a competitive advantage. There can be no assurance that 
the Company will not become subject to patent infringement claims or 
litigation or interference proceedings declared by the United States Patent 
and Trademark Office ("USPTO") to determine the priority of inventions. The 
defense and prosecution of intellectual property suits, USPTO interference 
proceedings and related legal and administrative proceedings are both costly 
and time-consuming. Litigation may be necessary to enforce patents issued to 
the Company, to protect trade secrets or know-how owned by the Company or to 
determine the enforceability, scope and validity of the proprietary rights of 
others. Any litigation or interference proceedings will result in substantial 
expense to the Company and significant diversion of effort by the Company's 
technical and management personnel. An adverse determination in litigation or 
interference proceedings to which the Company may become a a party, including 
any litigation that may arise against the Company as described in "Potential 
Litigation" below, could subject the Company to significant liabilities to 
third parties or require the Company to seek licenses from third parties or 
prevent the Company from selling its products in certain markets, or at all. 
Costs associated with settlements, licensing and similar arrangements, may be 
substantial and could include ongoing royalties. Furthermore, there can be no 
assurance that the necessary licenses would be available to the Company on 
satisfactory terms, if at all. Adverse determinations in a judicial or 
administrative proceeding or failure to obtain necessary licenses could 
prevent the Company from manufacturing and selling its products, which would 
have a material adverse effect on the Company's business, financial condition 
and results of operations.
      Congress enacted legislation, which became effective October 1, 1996, 
that places certain restrictions on the ability of medical device 
manufacturers to enforce certain patent claims, relating to surgical and 
medical methods, against medical practitioners. Such limitation in the 
enforceability of patent claims, relating to medical and surgical methods, 
against medical practitioners could have a material adverse effect on the 
Company's ability to protect its proprietary methods and procedures against 
medical practitioners.
      In addition to patents, the Company relies on trade secrets and 
proprietary know-how, which it seeks to protect, in part, through 
confidentiality and proprietary information agreements. There can be no 
assurance that such confidentiality or proprietary information agreements 
will not be breached, that the Company would have adequate remedies for any 
breach, or that the Company's trade secrets will not otherwise become known 
to or be independently developed by competitors.

POTENTIAL LITIGATION. 
Heartport, Inc. (formerly Stanford Surgical Technologies, Inc.), the former 
employer of the Company's founder and Chief Technical Officer, Charles S. 
Taylor, has alleged in certain correspondence that Mr. Taylor and the Company 
may have misappropriated trade secrets of the former employer and breached 
confidentiality obligations to the former employer. The former employer also 
claims an ownership interest in certain developments and products of the 
Company. The Company has agreed to provide for the defense of Mr. Taylor in 
the event that litigation is commenced. Litigation is subject to inherent 
uncertainties, especially in cases where complex technical issues are decided 
by a lay jury. Accordingly, no assurance can be given that if a lawsuit is 
commenced it would not be decided against the Company. Such an adverse 
determination could have a material adverse effect upon the Company's 
business, financial condition and results of operations.

DEPENDENCE UPON KEY PERSONNEL. 
The Company's ability to operate successfully depends in significant part 
upon the continued service of certain key scientific, technical, managerial 
and finance personnel, and its continuing ability to attract and retain 
additional highly qualified scientific, technical, managerial and finance 
personnel. Competition for such personnel is intense, and there can be no 
assurance that the Company can retain such personnel or that it can attract 
or retain other highly qualified scientific, technical, managerial and 
finance personnel in the future, including key manufacturing, sales and 
marketing personnel. The loss of key personnel or the inability to hire or 
retain qualified personnel could have a material adverse effect upon the 
Company's business, financial condition and results of operations. In 
addition, many employees of the Company, including a number of its key 
scientific, technical and managerial personnel, are subject to the terms of 
confidentiality agreements with respect to proprietary information of their 
former employers. The failure of these employees to comply with the terms of 
their agreements with, or other obligations to, such former employers could 
result in assertion of claims against the Company and such employees, which, 
if successful, could restrict their role with the Company and have a material 
adverse effect on the Company's business, financial condition and results of 
operations.

DEPENDENCE UPON SCIENTIFIC ADVISORS. 
The Company has established a Scientific Advisory Board including 
cardiothoracic surgery opinion leaders, prominent surgeons and leading 
interventional cardiologists who the Company believes have performed the vast 
majority of MIDCAB procedures. Members of the Scientific Advisory Board 
consult with the Company regarding research and development efforts at the 
Company, but are employed elsewhere on a full-time basis. As a result, they 
can only spend a limited amount of time on the Company's affairs. Although 
the Company has entered into consulting agreements, with terms ranging from 
six months to four years, and confidentiality agreements with each of the 
members of its Scientific Advisory Board, there can be no assurance that the 
consulting and confidentiality agreements between the Company and each of the 
members of the Scientific Advisory Board will not be terminated or breached, 
and there can be no assurance that any such agreements will be renewed 
upon expiration.


                                      18

LIMITED SALES, MARKETING AND DISTRIBUTION EXPERIENCE. 
The Company currently has a small sales and marketing organization. The 
Company intends to sell the CTS MIDCAB System in the United States and 
certain European countries through a direct sales force. In other markets, 
the Company intends to sell its products primarily through distributors or by 
means of collaborative arrangements. There can be no assurance that the 
Company will be able to build a larger direct sales force or marketing 
organization, that maintaining a direct sales force or marketing organization 
will be cost effective, or that the Company's sales and marketing efforts 
will be successful. There can be no assurance that the Company will be able 
to maintain agreements with distributors or collaborative arrangements, or 
that such distributors or collaborators will devote adequate resources to 
selling the Company's products. The Company has entered into distribution 
agreements for the sale of its products in certain countries. Therefore, the 
Company will be dependent upon the efforts of these third parties, and there 
can be no assurance that such efforts will be successful. Failure to build an 
effective sales and marketing organization or to establish effective 
distribution or collaborative relationships could have a material adverse 
effect on the Company's business, financial condition and results of 
operations.

NO MANUFACTURING EXPERIENCE; SCALE-UP RISK. 
The Company has no experience manufacturing its products in the volumes that 
would be necessary for the Company to achieve significant commercial sales. 
There can be no assurance that reliable, high-volume manufacturing can be 
established or maintained at commercially reasonable costs. Companies often 
encounter difficulties in scaling up production, including problems involving 
production yield, quality control and assurance, and shortages of qualified 
personnel. In addition, the Company's manufacturing facilities will be 
subject to GMP regulations, international quality standards and other 
regulatory requirements. Difficulties encountered by the Company in 
manufacturing scale-up or failure by the Company to implement and maintain 
its facilities in accordance with GMP regulations, international quality 
standards or other regulatory requirements could entail a delay or 
termination of production, which could have a material adverse effect on the 
Company's business, financial condition and results of operations.

POTENTIAL COMPONENT SHORTAGES; DEPENDENCE ON SOLE SOURCES OF SUPPLY. 
The Company contracts with third parties for the manufacture of certain 
components or the performance of certain processes involved in the 
manufacturing cycle. Some of these components and processes may only be 
available from single-source vendors. Any prolonged supply interruption or 
yield problems experienced by the Company due to a single-source vendor could 
have a material adverse effect on the Company's ability to manufacture its 
products under development until a new source of supply is qualified. As the 
Company increases production, it may from time to time experience lower than 
anticipated yields or production constraints, resulting in delayed product 
shipments, which could have a material adverse effect on the Company's 
business, financial condition and results of operation.

UNCERTAINTY RELATING TO THIRD-PARTY REIMBURSEMENT. 
In the United States, health care providers, such as hospitals and 
physicians, that purchase medical devices, such as the Company's products, 
generally rely on third-party payors, principally Medicare, Medicaid and 
private health insurance plans, to reimburse all or part of the cost of the 
procedure in which the medical device is being used. Reimbursement for 
cardiovascular surgery, including CABG surgery, using devices that have 
received FDA approval has generally been available in the United States. In 
addition, certain health care providers are moving toward a managed care 
system in which such providers contract to provide comprehensive health care 
for a fixed cost per person. The Company is unable to predict what changes 
will be made in the reimbursement methods utilized by third-party health care 
payors. The Company could be adversely affected by changes in reimbursement 
policies of government or private health care payors, particularly to the 
extent any such changes affect reimbursement for the procedures in which the 
Company's products are intended to be used. Failure by physicians, hospitals 
and other potential users of the Company's products to obtain sufficient 
reimbursement from health care payors for the procedure in which the 
Company's products are intended to be used or adverse changes in government 
and private third-party payors' policies toward reimbursement for such 
procedures could have a material adverse effect on the Company's business, 
financial condition and results of operations.
     Market acceptance of the Company's products in international markets 
will be dependent, in part, upon the availability of reimbursement within 
prevailing health care payment systems. Reimbursement and health care payment 
systems in international markets vary significantly by country, and include 
both government sponsored health care and private insurance. The Company 
intends to seek international reimbursement approvals, although there can be 
no assurance that any such approvals will be obtained in a timely manner, if 
at all, and failure to receive international reimbursement approvals could 
have a material adverse effect on market acceptance of the Company's products 
in the international markets in which such approvals are sought.

PRODUCT LIABILITY RISK; LIMITED INSURANCE COVERAGE. 
The development, manufacture and sale of medical products entail significant 
risk of product liability claims and product recalls. The Company's current 
product liability insurance coverage limits are $3,000,000 per occurrence and 
$3,000,000 in the aggregate, and there can be no assurance that such coverage 
limits are adequate to protect the Company from any liabilities it might 
incur in connection with the development, manufacture and sale of its 
products. In addition, the Company may require increased product liability 
coverage as product sales increase. Product liability insurance is expensive 
and in the future may not be available to the Company on acceptable terms, if 
at all. A successful product liability claim or series of claims brought 
against the Company in excess of its insurance coverage or a product recall 
could have a material adverse effect on the Company's business, financial 
condition and results of operations.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
CardioThoracic Systems, Inc. and Subsidiary

NOTE ONE
FORMATION AND BUSINESS OF THE COMPANY:
CardioThoracic Systems, Inc. (the Company) was incorporated in the state of
California on June 15, 1995. The Company acquired all of the intellectual
property assets from its predecessor, Informed Creation, a sole proprietorship,
and expensed the purchase price to research and development as purchased in
process research and development technology. The Company designs, develops,
manufactures and markets surgical products and systems for minimally invasive
cardiothoracic surgery. The Company's principal operations commenced in December
1996, at which time it emerged from the development stage.
     On March 29, 1996, the Company was reincorporated in the state of 
Delaware with the associated exchange of shares of each class and series of 
stock of the predecessor company for one share of each identical class and 
series of stock of the Delaware successor company having a par value of 
$0.001 per share for both common stock and preferred stock.
     The Company sold 5,117,500 shares of common stock (including 667,500 
shares from the exercise of the underwriter's over-allotment option) at 
$18.00 per share through an initial public offering in April 1996. Net 
proceeds (after underwriter's commissions and fees along with other costs 
associated with the offering) totaled approximately $84,223,000. Upon 
completion of the offering, all outstanding shares of preferred stock (a 
total of 5,025,000 shares) were converted into shares of common stock on a 
one-for-one basis.
     In the course of its development activities, the Company has sustained 
operating losses and expects such losses to continue through 1997. The 
Company will finance its operations primarily through its cash, cash 
equivalents and available-for-sale securities, together with existing credit 
facilities and future revenues. There can be no assurance that the Company 
will not require additional funding and should this prove necessary, the 
Company may sell additional shares of its common or preferred stock through 
private placement or further public offerings.

NOTE TWO
SUMMARY OF SIGNIFICANT 
ACCOUNTING POLICIES:

BASIS OF CONSOLIDATION:
The Company has a wholly owned subsidiary in Germany, CardioThoracic Systems, 
GmbH. This entity was formed in December 1996 but as of December 31, 1996, 
had yet to commence operations. The consolidated financial statements include 
the accounts of this wholly owned subsidiary. All intercompany balances and 
transactions have been eliminated.

STOCK SPLIT:
On August 25, 1995, the Company effected a 1.0306-for-1 common stock split. 
All common stock data in the accompanying financial statements has been 
retroactively adjusted to reflect the stock split.

USE OF ESTIMATES:
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements 
and the reported amounts of revenues and expenses during 
the reporting period. Actual results could differ from those estimates.

CASH AND CASH EQUIVALENTS AND AVAILABLE-FOR-SALE SECURITIES:
The Company considers all highly liquid investments purchased with original 
maturities of three months or less to be cash equivalents. Cash and cash 
equivalents include money market funds and various deposit accounts.
     The Company has classified its investments as "available-for-sale." Such 
investments are recorded at fair value and unrealized gains and losses, if 
material, are recorded as a separate component of equity until realized. 
Interest income is recorded using an effective interest rate, with associated 
premium or discount amortized to "investment income." The cost of securities 
sold is based upon the specific identification method.

INVENTORIES:
Inventories are stated at the lower of cost (determined on a first-in 
first-out basis) or market value.

DEPRECIATION:
Property and equipment are stated at cost and are depreciated on a 
straight-line basis over their estimated useful lives of three to five years. 
Leasehold improvements are amortized over their estimated useful lives, or 
the lease term, if shorter.

REVENUE RECOGNITION:
The Company recognizes revenue upon shipment of product to the customer, upon 
fulfillment of acceptance terms, if any, and when no significant contractual 
obligations remain outstanding.

RESEARCH AND DEVELOPMENT:
Research and development costs are charged to operations as incurred.

CONCENTRATION OF CREDIT RISK:
The Company's cash and cash equivalents are maintained at four financial 
institutions. Deposits in these institutions may exceed the amount of 
insurance provided on such deposits.
     For accounts receivable, management of the Company performs ongoing 
credit evaluations of its customers. At December 31, 1996, one customer 
accounted for 14% of net accounts receivable and 13% of total revenues, 
respectively.

                                      25

<PAGE>

     The Company's products require approvals from the Food and Drug 
Administration (FDA) and international regulatory agencies prior to the 
commencement commercialized sales. There can be no assurance that the 
Company's products will receive any of these required approvals. If the 
Company was denied such approvals, or such approvals were delayed, it would 
have a materially adverse impact on the Company.

INCOME TAXES:
The Company accounts for income taxes under Statement of Financial Accounting 
Standard (SFAS) No. 109, "Accounting for Income Taxes," which prescribes the 
use of the liability method whereby deferred tax asset or liability account 
balances are calculated at the balance sheet date using current tax laws and 
rates in effect for the year in which the differences are expected to affect 
taxable income. Valuation allowances are established when necessary to reduce 
deferred tax assets to the amounts expected to be realized.

RECLASSIFICATION:
Certain amounts in the financial statements have been reclassified to conform 
with the current year's presentation. The reclassification had no impact on 
previously reported net loss.

NET LOSS PER SHARE:
The net loss per share is computed using the weighted average number of 
shares of common stock outstanding. Common equivalent shares from stock 
options and preferred stock are excluded from the computation as their effect 
is anti-dilutive, except that, pursuant to the Securities and Exchange 
Commission Staff Accounting Bulletin, common and common equivalent shares 
issued at prices below the public offering price during the 12 months 
immediately preceding the initial filing date have been included in the 
calculation as if they were outstanding during all periods prior to the 
initial filing date (using the treasury stock method and the initial public 
offering price).

shares are subject to repurchase under these stock purchase agreements.

NOTE TEN
RELATED PARTIES:
In June 1995, the Company entered into a consulting and assignment agreement 
with a surgeon who serves on the Company's Scientific Advisory Board. Under 
the agreement, the surgeon will develop prototype instruments, participate in 
developing any testing protocols, provide clinical input with respect to 
current surgical procedures, provide evaluations of prototype products and 
test prototype and production products. In consideration, the Company will 
pay this surgeon $5,000 per month, with such payments retroactive to July 1, 
1995. Payments under this agreement totaled $60,000 and $30,000 in 1996 and 
1995, respectively. The assignment agreement assigned to the Company all this 
surgeon's rights, title and interest in and to a U.S. patent application 
entitled "Method For Coronary Artery Bypass." Concurrent with this agreement, 
the Company sold 103,060 shares of common stock to the surgeon for cash at 
$0.001 per share and will pay a 3% royalty on the first $10 million of net 
sales, 2% on the next $15 million of net sales and 1.5% on net sales above 
$25 million of future products covered by future potential patents on which 
this surgeon is the sole inventor. No royalty payments were made in 1996 and 
1995.
     Also in June 1995, the Company entered into a consulting agreement with 
a consulting company which is also a stockholder of the Company. Under the 
agreement, the consulting company provides the Company with the appropriate 
contacts to cardiac surgeons and other medical professionals for developing a 
Scientific Advisory Board, planning clinical trials and for other business 
purposes. In consideration, the Company sold 61,836 shares of common stock to 
this consulting company at $0.001 per share.
     In September 1995, the Company entered into an assignment agreement with 
an officer and director, the sole proprietor of Informed Creation, whereby 
the employee assigned to the Company all his right, title and interest in and 
to any and all original work of authorship, concepts, copyrights, 
copyrightable works, designs, developments, discoveries, formulae, ideas, 
inventions, improvements, manufacturing techniques, patents, patent 
applications, processes, trademarks and trade 

                                      29

secrets, including all rights to obtain, register, perfect and enforce these 
proprietary interests, which are related to or potentially useful in coronary 
bypass procedures, including, without limitation, less-invasive direct 
coronary artery bypass graft (CABG) procedures. In consideration of the 
assignment, the Company paid this employee $1,000 and expensed the purchase 
price to research and development as purchased in-process research and 
development technology.
     In February 1996, the company entered into a consulting agreement with a 
board member. The agreement requires this board member to provide consulting 
services with respect to the conception, development and clinical evaluation 
of devices, instruments and techniques for minimally invasive coronary artery 
bypass graft surgery (MIDCAB) for four years. In consideration for these 
consulting services, the Company granted to partnerships of which this board 
member is a general partner, nonstatutory options to purchase a total of 
90,000 shares of common stock of the Company at an exercise price of $0.10 
per share. The options were exercisable immediately, but subject to 
repurchase at cost in the event that both the agreement is terminated in 
accordance with its terms and this board member is no longer a member of the 
Company's Board of Directors. The repurchase right will lapse at the rate of 
1/48 of the shares each month beginning in March 1996. The Company will also 
pay royalties of 4% on the aggregate net sales of certain products sold by 
the Company until a total of $25,000,000 has been paid. Thereafter, the 
Company will have no further royalty obligations under this agreement. The 
partnerships exercised the stock options to purchase a total of 90,000 shares 
in February 1996. No royalties were paid during 1996.
     Also in February 1996, the Company entered into a development program 
agreement with a medical device company. This company is currently developing 
several minimally invasive cardiothoracic surgical products. Under the 
development program agreement, the Company will issue a purchase order in the 
amount of $30,000 to this company for their current prototype products. The 
Company will make development payments totaling $500,000 and issued a 
nonstatutory option to purchase 450,000 shares of common stock of the Company 
at an exercise price of $0.001 per share. All of the shares subject to the 
option will become exercisable on December 31, 1998 unless the development 
program agreement is terminated in accordance with its terms. However, the 
vesting of the options will be accelerated upon completion of certain 
milestones. Also, the Company will pay certain royalties based on revenue 
from certain product sales and sublicenses. The Company may terminate the 
agreement without cause on 90 days notice by paying a termination fee to this 
company in addition to all payments owed through the notice date. No royalty 
payments were made during 1996.

NOTES RECEIVABLE FROM OFFICERS:
In April 1996, the Company loaned an officer $300,000 pursuant to a provision 
in the officer's employment agreement. The resulting promissory note bears 
interest at the rate of 5.88% per annum and is due and payable in 37 
installments, the first of which shall be $75,000 due on April 29, 1997, 
followed by 36 equal monthly installments of $6,250 beginning on May 29, 
1997. Also, in June 1996, the Company loaned this officer an additional 
$55,000. The resultant promissory note bears interest at the rate of 5.88% 
per annum and is payable in two equal installments on January 5, 1997 and 
January 5, 1998 or termination of employment, if earlier. Should the 
officer's association with the Company continue through the due date of any 
installment payment under these notes, then the Company agrees to forgive all 
principal and interest due by the terms of the note for such installment. The 
Company amortizes the loan over the term of the notes on a straight line 
basis. As of December 31, 1996, principal and interest of $286,667 is 
outstanding under these notes.
     In May 1996, the Company loaned an officer $35,000. The resultant 
promissory note bears interest at 6.36% per annum and is due on the earlier 
of May 20, 2000 or termination of employment. At December 31, 1996, $35,000 
of principal and interest is outstanding on this note. The loan is 
collateralized by the officer's option to purchase common stock.
     In August 1996, the Company loaned an officer $750,000 which is due and 
payable on the earlier of August 16, 2000 or termination of employment. The 
resultant promissory note does not bear interest and is collateralized by the 
officer's holding of 75,000 shares of the Company's common stock. At December 
31, 1996, principal of $750,000 is outstanding on this note.
     In December 1996, the Company loaned an officer $200,000 pursuant to a 
provision in the officer's employment agreement. The resultant promissory 
note bears interest at 6.31% per annum and is due on the earlier of December 
31, 2000 or termination of employment. At December 31, 1996, principal and 
interest of $200,000 is outstanding on this note.

NOTE ELEVEN
INCOME TAXES:
At December 31, 1996, the Company has approximately $7,260,000 in federal and 
state net operating loss carryforwards to reduce future taxable income. These 
carryforwards expire in the year 2011 for federal and 2001 for state, if not 
utilized.
     The Tax Reform Act of 1986 limits the use of net operating loss and tax 
credit carryforwards in the case of an "ownership change" of a corporation. 
Any ownership changes, as defined, may restrict utilization of carryforwards.
     Temporary differences and carryforwards which gave rise to significant 
portions of deferred tax assets and liabilities are as follows:

                                                ------------------------------

     In Accordance with generally accepted accounting principles, a valuation 
allowance must be established for a deferred tax asset if it is more likely 
than not that a tax benefit may not be realized from the asset in the future. 
The Company has established a valuation allowance to the extent of its 
deferred tax assets due to uncertainties that a benefit can be realized in 
the future.


NOTE TWELVE
SUBSEQUENT EVENTS:
On January 28, 1997, the Board of Directors increased the number of common 
shares authorized under the Articles of Incorporation to 60,000,000 and 
increased the number of shares reserved for issuance under the Incentive 
Stock Plan by 600,000; each of these increases is subject to shareholder 
approval. In addition, the Board of Directors approved a shareholders rights 
plan pursuant to which the Board of Directors declared a dividend 
distribution of one preferred share purchase right on each outstanding share 
of the Company's Common Stock. Each right will enable stockholders to buy one 
one-thousandth of one share of the Company's Series A Participating Preferred 
Stock, a designated series of Preferred Stock for which each one-thousandth 
of a share has economic attributes and voting rights equivalent to one share 
of the Company's Common Stock, at an exercise price of $150. The rights 
become exercisable only in certain limited circumstances involving 
acquisitions of, or tender offers for, 15% or more of the Company's capital 
stock. For a limited period of time after the announcement of any such 
acquisition or offer, the rights are redeemable at a price of $.01 per right. 
After becoming exercisable, in certain more limited circumstances, each right 
entitles its holder to purchase for $150 an amount of Common Stock of the 
Company, or in certain circumstances, securities of the acquiror, having a 
then current market value equal to $300. The rights expire on January 28, 
2007.

cumulative period from November 3, 1993 (date of inception) to June 14, 1995. 
These financial statements are the responsibility of the management of the 
sole proprietorship. Our responsibility is to express an opinion on these 
financial statements based on our audits.
     We conducted our audits in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement. An audit includes examining on a test basis, 
evidence supporting the amounts and disclosures in the financial statements. 
An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall 
financial statement presentation. We believe that our audits provide a 
reasonable basis for our opinion.
     In our opinion, the financial statements referred to above present 
fairly, in all material respects, the financial position of Informed Creation 
(a development stage entity) as of June 14, 1995 the statements of 
operations, sole proprietorship capital and cash flows for the period from
