                                  Center Photo

  Description: Arthrocare System 2000 - This photo shows our radio frequency
controller unit in front of a three-control foot pedal which the surgeon uses
to select power level and functionality. Attached to the front of the
controller is a cable that supplies power to the disposable device, which is
affixed to the other end of the cable. The device lies on top of the coiled
cable. It consists of a plastic handle, shaft and the housing for the
electrodes.

  Caption: Our Coblation(TM)-based soft-tissue surgical system consists of an
assortment of disposable devices and a controller that supplies radio frequency
energy to the disposable devices.

                                 Device Photos

  Fanned beneath the center photo are three disposable devices. From left to
right they are the TurboVac, the Rejuvenation Stylet and the ENTec Plasma
Scalpel.

TurboVac(TM)

  Description: The TurboVac shows the tip of the wand at a 90 degree angle to
the shaft. The tip displays four pins which hold a five-hole screen through
which loose tissue is suctioned.

  Caption: The TurboVac combines suction with ablation for rapid removal of
soft tissue in arthroscopic surgery. Suction draws free floating tissue to the
electrodes for disintegration and removal from the surgical area.

Cosmetic Surgery Stylet

  Description: A wide curved handle with a channel on the underside. The
electrode array on the tip is a vertical array that protrudes about 1/8 inch
from the tip. Above the electrode array is a small hole for saline delivery
which is pumped through the channel in the handle.

  Caption: The cosmetic surgery stylet for dermatologic use is optimized for
performing in a dry field surgical environment. Saline is delivered to the
surface of the electrodes by way of a small tube in the handle of the device to
a point above the electrode array.

ENTec(TM) Plasma Scalpel(TM)

  Description: A thin handle with a vertical array of electrodes at the tip.
The tip curves about 35 degrees from the handle. There are channels both above
and below the tip for saline delivery and suction.

  Caption: The ENTec Plasma Scalpel offers complete fluid management. The
Plasma Scalpel provides both saline delivery and suction capability in
conjunction with tissue removal and the sealing of bleeding vessels.

                                    SUMMARY

   This summary highlights information contained elsewhere in this prospectus.
You should read the entire prospectus, including "Risk Factors" and the
consolidated financial statements and related notes, carefully before making an
investment decision.

                                   ArthroCare

   We are a medical device company that develops, manufactures and markets
products based on our patented Coblation(TM) technology. Our products allow
surgeons to operate with increased precision and accuracy, limiting damage to
surrounding tissue thereby reducing pain and speeding recovery for the patient.
Our products operate at lower temperatures than traditional electrosurgical or
laser surgery tools and enable surgeons to ablate or shrink soft tissue and to
simultaneously seal bleeding vessels. Ablation is the disintegration or removal
of tissue. Our soft-tissue surgery systems consist of a controller unit and an
assortment of disposable devices that are specialized for specific types of
surgery. We believe our Coblation technology can replace the multiple surgical
tools traditionally used in soft-tissue surgery procedures with one multi-
purpose surgical system.

   Coblation technology is applicable across many soft-tissue surgical markets.
Our systems are used to perform many types of arthroscopic surgery. Our
strategy includes applying our patented Coblation technology to a broad range
of other soft-tissue surgical markets, including cosmetic surgery, ear, nose
and throat, or ENT, surgery, spinal surgery and various cardiology
applications. We have formed the following business units for commercialization
of our technology in non-orthopedic markets: Visage(R), to commercialize our
cosmetic surgery products for use in various cosmetic surgery procedures;
ENTecTM, to commercialize our ENT surgery products for use in head and neck
surgical procedures; and AngioCareTM, to commercialize our technology in the
cardiac surgery and interventional cardiology markets.

   We have received 510(k) clearance from the Food and Drug Administration, the
FDA, to market our Arthroscopic System for use in arthroscopic surgery of the
knee, shoulder, ankle, elbow, wrist and hip, and our Arthroscopic System is CE
marked for use in arthroscopic surgery. The CE Mark is a requirement to sell
our products in most of Western Europe. Our Cosmetic Surgery System is CE
marked for general dermatologic, skin resurfacing and wrinkle reduction
procedures, and we have received 510(k) clearance for use of our Cosmetic
Surgery System in general dermatologic procedures in the United States. We are
pursuing additional clearances that will allow our cosmetic surgery products to
be marketed in the United States specifically for skin resurfacing and wrinkle
reduction. Our ENT surgery system is CE marked, and we have received 510(k)
clearances for use of our ENT surgery system in general head, neck, oral and
sinus surgery procedures in the United States. Our Spinal Surgery System is CE
marked, and we have applied for 510(k) clearance in the United States to market
this system for spinal surgery. We have received 510(k) clearance to market
products based on Coblation technology for general surgery.

   We commercially introduced our Arthroscopic System in December 1995 and have
derived substantially all of our sales from this system. As of July 3, 1999, we
had shipped more than 5,000 controller units and more than 450,000 disposable
devices for a variety of indications. We are marketing and selling our
arthroscopic and ENT surgery products in the United States through a network of
independent distributors supported by regional managers. We have more than 35
distributors representing more than 225 field sales representatives in the
United States. We have also established distribution capability in Europe,
Australia, New Zealand, Korea, Japan, Taiwan, Canada, Mexico, the Caribbean,
Russia, South Africa, the Middle East, Northern Africa and South and Central
America. In addition, we are marketing and selling our Spinal Surgery System
internationally and are building our domestic distribution capabilities in this
area in anticipation of 510(k) clearance. In order to market our spinal surgery
products, we plan to utilize existing distributors, add new distributors that
specialize in spinal surgery products and add additional regional managers both
domestically and internationally. We have signed an exclusive worldwide
distribution agreement with Collagen Aesthetics, Inc., which was recently
acquired by Inamed Corporation, for our cosmetic surgery products. In addition,
we have entered into a license agreement under which the SciMed division of
Boston Scientific Corporation will develop, obtain regulatory approval for and
market products based on Coblation technology for a specific application within
cardiology.

                                  RISK FACTORS

   Any investment in shares of our common stock involves a high degree of risk.
You should consider carefully the following information about these risks,
together with the other information contained in this prospectus, before you
decide to buy our common stock. If any of the following risks actually occur,
our business, financial condition, results of operations and future growth
prospects would likely be materially adversely affected. In these
circumstances, the market price of our common stock could decline, and you may
lose all or part of the money you paid to buy our common stock.

We Are Dependent Upon Our Arthroscopic System

   We commercially introduced our Arthroscopic System in December 1995. Since
our Arthroscopic System accounts for substantially all of our product sales, we
are highly dependent on its sales. Our spinal surgery, cosmetic surgery, and
ENT surgery products have only recently become available, and to date, we have
sold only a small number of units. We cannot assure you that we will be able to
continue to manufacture arthroscopy products in commercial quantities at
acceptable costs, or that we will be able to continue to market such products
successfully.

   To achieve increasing disposable device sales over time, we believe we must
continue to penetrate the market in knee procedures, expand physicians'
education with respect to Coblation technology and continue working on new
product development efforts specifically for knee applications. Furthermore, in
order to maintain and increase current market penetration we must be aggressive
in increasing our installed base of controllers to generate increased
disposable device revenue. To date, we have placed our arthroscopic controllers
at substantial discounts in order to stimulate demand for our disposable
devices.

   We believe that surgeons will not use our products unless they determine,
based on experience, clinical data and other factors, that these systems are an
attractive alternative to conventional means of tissue ablation. There are only
a few independently published clinical reports and limited long-term clinical
follow-up to support the marketing efforts for our Arthroscopic System. We
believe that continued recommendations and endorsements by influential
arthroscopic surgeons are essential for market acceptance of our Arthroscopic
System. If our Coblation technology does not continue to receive endorsement by
influential surgeons or our long-term data does not support our current claims
of efficacy, our business, financial condition, results of operations and
future growth prospects could be materially adversely affected.

Commercial Success of Our Non-Arthroscopic Products Is Uncertain

   We have developed several new applications for our Coblation technology in
spinal surgery, cosmetic surgery and ENT surgery. Additionally we have
established a program to explore the application of our Coblation technology in
various areas within cardiology. Our products for these non-arthroscopic
indications are in various stages of commercialization and development, and we
may be required to undertake time-consuming and costly commercialization,
development and additional regulatory approval activities. We are awaiting
510(k) clearance in the United States to market our Spinal Surgery System
specifically for use in spinal surgery and to market our Cosmetic Surgery
System specifically for skin resurfacing and wrinkle reduction. If we do not
receive these clearances we will be unable to market these products for these
specific indications and our business, financial condition, results of
operations and future growth prospects could be materially adversely affected.
We cannot assure you that product development will ever be successfully
completed, that regulatory clearances or approvals, if applied for, will be
granted by the FDA or foreign regulatory authorities on a timely basis, if at
all, or that the products will ever achieve commercial acceptance.

   We may have to make a significant investment in additional preclinical and
clinical testing, regulatory, physician training and sales and marketing
activities to further develop and commercialize the spinal surgery, cosmetic
surgery, ENT surgery and cardiology product lines. Although we believe that
these products offer

                                       7
<PAGE>

certain advantages, we cannot assure you that these advantages will be
realized, or if realized, that these products will result in any meaningful
benefits to physicians or patients.

   Development and commercialization of our current and future non-arthroscopic
products are subject to the risks of failure inherent in the development of new
medical devices. These risks include the following:

  . that such products will not be easy to use, will require extensive
    training or will not be cost-effective;

  . that we will experience delays in testing or marketing;

  . that such testing or marketing will result in unplanned expenditures or
    in expenditures above those anticipated by us;

  . that our products will not be proven safe or effective;

  . that third parties will develop and market superior or equivalent
    products;

  . that such products will fail to receive necessary regulatory clearances
    or approvals;

  . that such products will be difficult or uneconomical to manufacture on a
    commercial scale; and

  . that proprietary rights of third parties will preclude us and our
    collaborative partners from marketing such products.

   In addition, the success of our non-arthroscopic products will depend on
their adoption as alternatives to conventional means of tissue ablation.
Clinical experience and follow-up data for our non-arthroscopic indications are
limited, and we have sold only a small number of units to date. We believe that
recommendations and endorsement of influential physicians are essential for
market acceptance of our products.

   For information regarding the status of our regulatory approvals for our
products, see the information under the heading "Government Regulation" in the
section entitled "Business."

We Have Limited Marketing and Sales Experience

   We currently have limited experience in marketing and selling our products.
To the extent that we have established or will enter into distribution
arrangements for the sale of our products, we are and will be dependent upon
the efforts of third parties. We are marketing and selling our arthroscopic
surgery and ENT surgery product lines in the United States through a network of
independent distributors supported by regional sales managers and a small
direct sales force. These distributors sell arthroscopy and ENT surgery devices
for a number of other manufacturers. In addition, we are marketing and selling
our Spinal Surgery System internationally and are building our domestic
distribution capabilities in this area in anticipation of 510(k) clearance. In
order to market our spinal surgery products, we plan to utilize existing
distributors, add new distributors that specialize in spinal surgery products
and add additional regional managers, both domestically and internationally. We
cannot assure you that these distributors will commit the necessary resources
to effectively market and sell our arthroscopic surgery, spinal surgery or ENT
surgery product lines, or that they will be successful in selling our products.

   We have recently established a marketing presence in various countries and
we cannot assure you that these newly established operations will be
successful. In order to successfully market our products internationally, we
will need to address many issues with which we have little or no experience,
including the securing of necessary regulatory approvals in international
markets and the potential reuse of our disposable devices by our customers.
Even if we are able to successfully deal with these issues, we cannot assure
you that we will be able to establish successful distribution capabilities
internationally or receive favorable pricing for our products. In addition, we
may face currency exchange risks as part of our international expansion. To the
extent our marketing and sales efforts are unsuccessful, our business,
financial condition, results of operations and future growth prospects may be
materially adversely affected.

                                       8
<PAGE>

We Have Limited Manufacturing Experience

   To be successful, we must manufacture our products in commercial quantities
in compliance with regulatory requirements at acceptable costs. At the present
time, we have limited manufacturing experience. Our manufacturing operations
consist of an in-house assembly operation for the manufacture of disposable
devices and controllers. We currently produce 32 models of disposable devices
utilizing different functionalities,
including suction and fluid management. As we increase the number of product
designs for our disposable devices, the complexity of our manufacturing
processes will increase. We manufacture three different controller models.
Although the manufacturing processes for the controllers designed to date are
substantially the same, we cannot be certain that we will be able to continue
to manufacture these controllers without additional expense and capabilities.
We could also encounter difficulties in manufacturing our current or future
products which could reduce yields, result in supply disruptions and adversely
affect our gross margins. If we have delays in manufacturing, we will not have
adequate finished inventory to meet our needs. If our quality assurance
programs do not continue to meet the demands of the complexity and capacity of
the products we manufacture, we may experience product returns.

We Are Dependent on Key Suppliers

   We depend on several sole source suppliers for some of our product
components, including one component that we include in substantially all of our
disposable devices. If the supply of materials from a sole source supplier were
interrupted, replacement or alternative sources might not be readily obtainable
due to the regulatory requirements applicable to our manufacturing operations.
In addition, a new or supplemental filing with applicable regulatory
authorities may require clearance prior to our marketing a product containing
new material. This clearance process may take a substantial period of time and
we cannot assure you that we would be able to obtain the necessary regulatory
approval for the new material to be used in our products on a timely basis, if
at all. This could create supply disruptions that would materially adversely
affect our business, financial condition, results of operations and future
growth prospects.

   In addition, we use a single subcontractor to sterilize the disposable
devices. We cannot assure you that we can identify and qualify an alternate
sterilizer. Our inability to secure an alternative sterilizer, if required,
would limit our ability to manufacture disposable devices and could have a
material adverse effect on our business, financial condition, results of
operations and future growth prospects.

Our Operating Results Will Fluctuate

   We have experienced significant operating losses since inception and, as of
July 3, 1999, we had an accumulated deficit of $25.9 million. Results of
operations may fluctuate significantly from quarter to quarter due to many
factors, including the following:

  . the introduction of new product lines;

  . increased penetration in existing applications;

  . product returns;

  . achievement of research and development milestones;

  . the amount and timing of receipt and recognition of license fees;

  . manufacturing or supply disruptions;

  . timing of expenditures;

  . absence of a backlog of orders;

  . receipt of necessary regulatory approvals;

  . the level of market acceptance for our products;

                                       9
<PAGE>


  . timing of the receipt of orders and product shipments; and

  . promotional programs for our products.

   We cannot assure you that future quarterly fluctuations will not adversely
affect our business, financial condition, results of operations or future
growth prospects. Our revenues and profitability will be critically dependent
on whether or not we can successfully continue to market our Coblation-based
technology product lines. We cannot assure you that we will maintain or
increase our revenues or level of profitability.

We Face Intense Competition

   The markets for our current and potential products are intensely
competitive. These markets include arthroscopy, spinal surgery, ENT surgery,
cosmetic surgery, and cardiology. We cannot assure you that other companies
will not succeed in developing technologies and products that are more
effective than ours or that would render our technology or products obsolete or
uncompetitive in these markets.

   In arthroscopy, we compete against companies such as Johnson & Johnson,
Smith & Nephew, Inc., Conmed Corporation, Stryker Corp. and Oratec
Interventions, Inc. which market products to remove or shrink tissue.
Specifically, Johnson & Johnson is currently marketing worldwide a bipolar
electrosurgical system for tissue ablation. We are also aware of additional
competitors that may commercialize products using technology similar to ours.
In spinal surgery, we compete against companies which market products to remove
tissue and treat spinal disorders. In ENT surgery, we compete against companies
that offer manual instruments, such as Smith & Nephew, Inc., Stryker Corp.,
Conmed Corporation, and Xomed Surgical Products, Inc., which was recently
acquired by Medtronic, Inc. In addition, we compete with companies that develop
and market lasers for various ENT surgery applications, including ESC Medical
Systems Ltd. Smaller companies, including Somnus Medical Technologies Inc.,
Elmed Inc. and Ellman International, Inc. also sell medical devices for the
treatment of various ENT disorders including snoring and obstructive sleep
apnea. In cosmetic surgery, we compete against companies such as Coherent
Medical Group, and ESC Medical Systems Ltd. which market lasers for use in this
field. In addition, other large companies manufacture and sell medical devices
that use radio frequency energy for certain applications in dermatology and
cosmetic surgery. In cardiology, we may compete with companies which use lasers
to treat cardiovascular disease. Other approaches to alleviating cardiovascular
disease, including drugs or other surgical approaches, may also be competitive.

   Many of our competitors have significantly greater financial, manufacturing,
marketing, distribution and technical resources than we do. Some of these
companies offer broad product lines that they may offer as a single package and
frequently offer significant discounts as a competitive tactic. For example, in
order to compete successfully, we anticipate that we may have to continue to
offer substantial discounts on our controllers in order to increase demand for
our disposable devices, and that this competition could have a material adverse
effect on our business, financial condition, results of operations and future
growth prospects. Furthermore, some of our competitors utilize purchasing
contracts that link discounts on the purchase of one product to purchases of
other products in their broad product lines. Many of the hospitals in the
United States have purchasing contracts with our competitors. Accordingly,
customers may be dissuaded from purchasing our products rather than the
products of these competitors to the extent the purchase would cause them to
lose discounts on products.

We Face Uncertainty Over Reimbursement

   Failure by physicians, hospitals and other users of our products to obtain
sufficient reimbursement from health care payors for procedures in which our
products are used or adverse changes in governmental and private third-party
payors' policies toward reimbursement for such procedures would have a material
adverse effect on our business, financial condition, results of operations and
future growth prospects. Reimbursement for arthroscopic, spinal surgery and ENT
surgery procedures performed using devices that have received FDA approval has
generally been available in the United States. Typically, cosmetic surgery
procedures are not reimbursed.

                                       10
<PAGE>

   We are unable to predict what changes will be made in the reimbursement
methods used by third-party health care payors. In addition, some health care
providers are moving toward a managed care system in which providers contract
to provide comprehensive health care for a fixed cost per person. Managed care
providers are attempting to control the cost of health care by authorizing
fewer elective surgical procedures. We anticipate that in a prospective payment
system, such as the diagnosis related group system utilized by Medicare, and in
many managed care systems used by private health care payors, the cost of our
products will be incorporated into the overall cost of the procedure and that
there will be no separate, additional reimbursement for our products. We
anticipate that hospital administrators and physicians will justify the use of
our products by the apparent cost savings and clinical benefits that we believe
will be derived from the use of our products. However, we cannot assure you
that this will be the case.

   If we obtain the necessary international regulatory approvals, market
acceptance of our 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. We intend to seek international
reimbursement approvals, although we cannot assure you that any such approvals
will be obtained in a timely manner, if at all.

Our Business Depends on Attracting and Retaining Collaborators and Licensors

   In order to successfully develop and commercialize certain products, we may
enter into collaborative or licensing arrangements with medical device
companies and other entities to fund and complete our research and development
activities, pre-clinical and clinical testing, manufacturing, regulatory
approval activities and to achieve successful commercialization of future
products. We have signed an exclusive, worldwide distribution agreement with
Collagen Aesthetics, Inc. for our cosmetic surgery products. We have also
entered into a license agreement under which Boston Scientific Corporation will
help develop, obtain regulatory approval for and market products based on our
Coblation technology for myocardial revascularization procedures. See the
information under the heading "Collaborative Arrangements" in the section
entitled "Business" for a discussion of these arrangements.

   Our participation in collaborative and licensing arrangements with third
parties subjects us to a number of risks. Collaborative partners typically have
significant discretion in electing whether to pursue any of the planned
activities. We cannot control the amount and timing of resources our
collaborative partners may devote to our products, and we cannot assure you
that our partners will perform their obligations as expected. Business
combinations or significant changes in a corporate partner's business strategy
may adversely affect that partner's ability to meet its obligations under the
arrangements. For example, Collagen Aesthetics, Inc. was recently acquired by
Inamed Corporation. If a collaborative partner were to terminate or breach its
agreement with us, or otherwise fail to complete its obligations in a timely
manner, our business, financial condition, results of operations and prospects
would be materially adversely affected. To the extent that we are not able to
establish further collaborative arrangements or that any or all of our existing
collaborative arrangements are terminated, we would be required to seek new
collaborative arrangements or to undertake commercialization at our own
expense, which could significantly increase our capital requirements, place
additional strain on our human resource requirements and limit the number of
products which we would be able to develop and commercialize. In addition, we
cannot assure you that our existing and future collaborative partners will not
pursue alternative technologies or develop alternative products either on their
own or in collaboration with others, including our competitors.

   We cannot assure you that disputes will not arise in the future with respect
to the ownership of rights to any technology or products developed with any
collaborative partner. Lengthy negotiations with potential new collaborative
partners or disagreements between established collaborative partners and us
could lead to delays in or termination of the research, development or
commercialization of certain products or result in litigation or arbitration
that would be time consuming and expensive. Failure by any collaborative
partner to commercialize successfully any product candidate to which it has
obtained rights from us, or the decision by a collaborative

                                       11
<PAGE>

partner to pursue alternative technologies or commercialize or develop
alternative products, either on its own or in collaboration with others, could
have a material adverse effect on our business, financial condition, results of
operations and future growth prospects.

We May Be Unable to Effectively Protect Our Intellectual Property

   Our ability to compete effectively depends in part on developing and
maintaining the proprietary aspects of our Coblation technology. We believe
that our issued patents are directed at, among other things, the core
technology used in our soft-tissue surgery systems, including both multi-
electrode and single electrode configurations of our disposable devices, as
well as the use of Coblation technology in specific surgical procedures.

   We cannot assure you that the patents we have obtained, or any patents we
may obtain as a result of our pending U.S. or international patent
applications, will provide any competitive advantages for our products. We also
cannot assure you that those patents will not be successfully challenged,
invalidated or circumvented in the future. In addition, we cannot assure you
that competitors, many of which have substantial resources and have made
substantial investments in competing technologies, have not already applied for
or obtained, or will not seek to apply for and obtain, patents that will
prevent, limit or interfere with our ability to make, use and sell our products
either in the United States or in international markets. Patent applications
are maintained in secrecy for a period after filing. We may not be aware of all
of the patents and patent applications potentially adverse to our interests.

   A number of medical device and other companies and universities and research
institutions have filed patent applications or have issued patents relating to
monopolar and/or bipolar electrosurgical methods and apparatus. We have
received, and we may receive in the future, notifications of potential
conflicts of existing patents, pending patent applications or challenges to the
validity of existing patents. In addition, we have become aware of, and may
become aware of in the future, patent applications and issued patents that
relate to our products and/or the surgical applications and issued patents and,
in some cases, have obtained internal and/or external opinions of counsel
regarding the relevance of certain issued patents to our products. We do not
believe that our products currently infringe any valid and enforceable claims
of the issued patents that we have reviewed. However, if third-party patents or
patent applications contain claims infringed by our technology and such claims
are ultimately determined to be valid, we may not be able to obtain licenses to
those patents at a reasonable cost, if at all, or be able to develop or obtain
alternative technology. Our inability to do either would have a material
adverse effect on our business, financial condition, results of operations and
prospects. We cannot assure you that we will not have to defend ourselves in
court against allegations of infringement of third-party patents, or that such
defense would be successful.

   In addition to patents, we rely on trade secrets and proprietary know-how,
which we seek to protect, in part, through confidentiality and proprietary
information agreements. We require our key employees and consultants to execute
confidentiality agreements upon the commencement of an employment or consulting
relationship with us. These agreements generally provide that all confidential
information, developed or made known to the individual during the course of the
individual's relationship with us, is to be kept confidential and not disclosed
to third parties. These agreements also generally provide that inventions
conceived by the individual in the course of rendering services to us shall be
our exclusive property. We cannot assure you that employees will not breach
such agreements, that we would have adequate remedies for any breach or that
our trade secrets will not otherwise become known to or be independently
developed by competitors.

We May Become Subject to Patent Litigation

   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. We cannot assure you that we will not become subject
to patent infringement claims or litigation or interference proceedings
declared by the United States Patent and

                                       12
<PAGE>

Trademark Office, the USPTO, to determine the priority of inventions. On
February 13, 1998, we filed a lawsuit against Ethicon, Inc., Mitek Surgical
Products, a division of Ethicon, Inc., and GyneCare, Inc. alleging, among other
things, infringement of several of our patents. The parties subsequently
settled this lawsuit. Under the terms of the settlement, Ethicon, Inc. has
licensed our U.S. patents for current products in the arthroscopy and
gynecology markets. The settlement agreement also established a procedure for
resolution of certain potential intellectual property disputes in these two
markets without litigation.

   Defending and prosecuting intellectual property suits, USPTO interference
proceedings and related legal and administrative proceedings are costly and
time-consuming. Further litigation may be necessary to enforce our patents, to
protect our trade secrets or know-how or to determine the enforceability, scope
and validity of the proprietary rights of others. Any litigation or
interference proceedings will be costly and will result in significant
diversion of effort by technical and management personnel. An adverse
determination in any of the litigation or interference proceedings to which we
may become a party could subject us to significant liabilities to third
parties, require us to license disputed rights from third parties or require us
to cease using such technology, which would have a material adverse effect on
our business, financial condition, results of operations and future growth
prospects. Patent and intellectual property disputes in the medical device area
have often been settled through licensing or similar arrangements, and could
include ongoing royalties. We cannot assure you that we can obtain the
necessary licenses on satisfactory terms, if at all.

The Market Price of Our Stock May Be Highly Volatile

   Within the last 12 months our common stock has traded between a range of
$11.25 and $69.25 per share. The market price of our common stock could
continue to fluctuate substantially due to a variety of factors, including:

  . quarterly fluctuations in results of our operations;

  . our ability to successfully commercialize our products;

  . announcements regarding results of regulatory approval filings, clinical
    studies or other testing, technological innovations or new commercial
    products by us or our competitors;

  . developments concerning government regulations, proprietary rights or
    public concern as to the safety of technology;

  . the execution of new collaborative agreements and material changes in our
    relationships with our business partners;

  . market reaction to acquisitions and trends in sales, marketing, and
    research and development;

  . changes in earnings estimates by analysts;

  . sales of common stock by existing stockholders; and

  . economic and political conditions.

   The market price for our common stock may also be affected by our ability to
meet analysts' expectations. Any failure to meet such expectations, even
slightly, could have an adverse effect on the market price of our common stock.
In addition, the stock market is subject to extreme price and volume
fluctuations. This volatility has had a significant effect on the market prices
of securities issued by many companies for reasons unrelated to the operating
performance of these companies. In the past, following periods of volatility in
the market price of a company's securities, securities class action litigation
has often been instituted against the company. If similar litigation were
instituted against us, it could result in substantial costs and a diversion of
our management's attention and resources, which could have an adverse effect on
our business, results of operations and financial condition. See "Price Range
of Common Stock" and "Dividend Policy."

We Are Involved In A Number Of Legal Proceedings

   We are currently involved in ongoing litigation. In June 1998, we announced
that we had entered into an exclusive worldwide marketing and distribution
agreement with Xomed Surgical Products for our products in the ENT surgery
market. On February 4, 1999, Xomed filed a complaint against us alleging breach
of contract. On February 5, 1999, we terminated this agreement. In a separate
action, California Medical, Inc. filed a complaint in California state court
against us on February 4, 1999 alleging breach of contract, interference with
contractual and economic relations, trade libel, misappropriation of trade
secrets, misrepresentation and unfair competition. California Medical is a
former distributor of our products in Northern California. As a result of a
hearing on our motion to dismiss, California Medical, Inc. filed an amended
complaint on August 9, 1999, in which they dropped the causes of action
alleging misrepresentation. In another action, on March 24, 1999, one of our
former employees filed a complaint of action for sexual harassment. If these
legal proceedings are adversely adjudicated or settled, they could have a
material adverse effect on our financial condition, results of operations and
future growth prospects. The defense of these actions is expensive and may
divert management's attention from our core business.

We Must Obtain Governmental Clearances Or Approvals Before We Can Sell Our
Products; We Must Continue To Comply With Applicable Laws and Regulations

 United States

   Our products are considered medical devices and are subject to extensive
regulation in the United States. We must obtain premarket clearance or approval
by the FDA for each of our products and indications before they can be
commercialized. FDA regulations are wide ranging and govern, among other
things:

  . product design and development;

  . product testing;

  . product labeling;

  . product storage;

  . premarket clearance or approval;

  . advertising and promotion; and

  . product sales and distribution.

   Noncompliance with applicable regulatory requirements can result in
enforcement action, which may include:

  . warning letters;

  . fines, injunctions and civil penalties against us;

  . recall or seizure of our products;

  . operating restrictions, partial suspension or total shutdown of our
    production;

  . refusing our requests for premarket clearance or approval of new
    products;

  . withdrawing product approvals already granted; and

  . criminal prosecution.

   Unless an exemption applies, before we can introduce a new medical device
into the United States market, we must obtain FDA clearance of a 510(k)
premarket notification or approval of a premarket approval application, or PMA
application. If we can establish that our device is "substantially equivalent"
to a "predicate device," i.e., a legally marketed Class I or Class II device or
a preamendment Class III device (i.e., one that was in commercial distribution
before May 28, 1976) for which the FDA has not called for PMAs, we

                                       14
<PAGE>

may seek clearance from the FDA to market the device by submitting a 510(k)
premarket notification. The 510(k) premarket notification will need to be
supported by appropriate data, including, in some cases, clinical data,
establishing the claim of substantial equivalence to the satisfaction of the
FDA.

   We have received 510(k) clearance to market our Arthroscopic System for
surgery of the knee, shoulder, elbow, wrist, hip and ankle joints. We have
submitted requests for 510(k) clearance in the United States to market our
Spinal Surgery System. In addition, we have received 510(k) clearance to market
our Cosmetic Surgery System in general dermatology procedures. We are also
pursuing additional clearances that will allow us to market our cosmetic
surgery products for skin resurfacing and wrinkle reduction. We have received
510(k) clearance to market the ENT surgery system in general head and neck
surgical procedures, as well as minimally-invasive sinus surgery. We cannot
assure you that we will be able to obtain necessary clearances or approvals to
market any other products, or existing products for new intended uses, on a
timely basis, if at all. Delays in receipt or failure to receive clearances or
approvals, the loss of previously received clearances or approvals, or failure
to comply with existing or future regulatory requirements could have a material
adverse effect on our business, financial condition, results of operations and
future growth prospects.

   After a device receives 510(k) clearance, any modification that could
significantly affect its safety or effectiveness, or that would constitute a
major change in the intended use of the device, requires a new 510(k)
clearance. The FDA requires each manufacturer to make this determination in the
first instance, but the FDA can review any such decision. If the FDA disagrees
with a manufacturer's decision not to seek a new 510(k) clearance, the agency
may retroactively require the manufacturer to submit a premarket notification
requesting 510(k) clearance. The FDA also can require the manufacturer to cease
marketing and/or recall the modified device until 510(k) clearance is obtained.
We have modified some of our marketed devices, but have determined that, in our
view, new 510(k) clearances are not required. No assurance can be given that
the FDA would agree with any of our decisions not to seek 510(k) clearance. If
the FDA requires us to seek 510(k) clearance for any modification, the FDA also
may require us to cease marketing and/or recall the modified device until we
obtain a new 510(k) clearance.

   If we cannot establish that a proposed device is substantially equivalent to
a legally marketed device, we must seek premarket approval through submission
of a PMA application. A PMA application must be supported by extensive data,
including, in many instances, preclinical and clinical trial data, as well as
extensive literature to prove the safety and effectiveness of the device. If
necessary, we will file a PMA application for approval to sell our potential
products. The PMA process can be expensive, uncertain and lengthy. We cannot
assure you that we will be able to obtain PMA approvals on a timely basis, if
at all, and delays in receipt or failure to receive approvals, could have a
material adverse effect on our business, financial condition, results of
operations and future growth prospects.

   We are also required to demonstrate and maintain compliance with the Quality
System Regulation, or QSR. The QSR incorporates the requirements of Good
Manufacturing Practice and relates to product design, testing, and
manufacturing quality assurance, as well as the maintenance of records and
documentation. The FDA enforces the QSR through inspections. We cannot assure
you that we or our key component suppliers are or will continue to be in
compliance, will not encounter any manufacturing difficulties, or that we or
any of our subcontractors or key component suppliers will be able to maintain
compliance with regulatory requirements. Failure to do so will have a material
adverse effect on our business, financial condition, results of operations and
future growth prospects.

   We may not promote or advertise our products for uses not within the scope
of our clearances or approvals or make unsupported safety and effectiveness
claims. These determinations can be subjective. We cannot assure you that the
FDA would agree that all of our promotional claims are permissible or that the
FDA will not require us to revise our promotional claims or take enforcement
action against us based upon our labeling and promotional materials.


                                       15

 International

   International sales of our products are subject to strict regulatory
requirements. The regulatory review process varies from country to country. We
have obtained regulatory clearance to market the Arthroscopic System in Europe,
Japan, Australia, Taiwan, Korea, Canada and Mexico, to market our cosmetic
surgery products in Europe and Canada and to market our ENT surgery products
and our spinal surgery products in Europe, but we have not obtained any other
international regulatory approvals in other international markets. We cannot
assure you that we will obtain such clearances and approvals on a timely basis,
or at all.

   For European distribution, we have received ISO 9001/EN46001 certification
and the EC Certificate pursuant to the European Union Medical Device Directive
93/42/EEC, allowing us to CE mark our products after assembling appropriate
documentation. ISO 9001/EN46001 certification standards for quality operations
have been developed to ensure that companies know the standards of quality on a
worldwide basis. Failure to maintain the CE Mark will preclude us from selling
our products in Europe. We cannot assure you that we will be successful in
maintaining certification requirements.

We Face Product Liability Risks and May Not Be Able to Obtain Adequate
Insurance

   The development, manufacture and sale of medical products involves
significant risk of product liability claims. Our current product liability
insurance coverage limits are $7.0 million per occurrence and $7.0 million in
the aggregate. We cannot assure you that such coverage limits are adequate to
protect us from any liabilities we might incur in connection with the
development, manufacture and sale of our products. In addition, we may require
increased product liability coverage as potential products are successfully
commercialized. Product liability insurance is expensive and may not be
available to us in the future on acceptable terms, if at all. We have not
received any product liability claims to date. However, a successful product
liability claim or series of claims brought against us in excess of our
insurance coverage could have a material adverse effect on our business,
financial condition, results of operations and future growth prospects.

We May Be Unable to Attract and Retain Personnel

   We are dependent upon a number of key management and technical personnel.
The loss of the services of one or more key employees or consultants could have
a material adverse effect on our business, financial condition, results of
operations and future growth prospects. Our success will also depend on our
ability to attract and retain additional highly qualified management and
technical personnel. We face intense competition for qualified personnel, many
of whom are often subject to competing employment offers, and we cannot assure
you we will be able to attract and retain such personnel. Furthermore, our
scientific advisory board members are all otherwise employed on a full-time
basis. As a result, the scientific advisory board members are not available to
devote their full time or attention to our business.

Delaware Law, Provisions in Our Charter and Our Stockholder Rights Plan Could
Make the Acquisition of Our Company By Another Company More Difficult

   Our stockholder rights plan and certain provisions of our certificate of
incorporation and bylaws may have the effect of making it more difficult for a
third party to acquire, or of discouraging a third party from attempting to
acquire, control of our company. This could limit the price that certain
investors might be willing to pay in the future for shares of our common stock.
Some provisions of our certificate of incorporation and bylaws allow us to
issue preferred stock without any vote or further action by the stockholders,
to eliminate the right of stockholders to act by written consent without a
meeting, to specify procedures for director nominations by stockholders and
submission of other proposals for consideration at stockholder meetings, and to
eliminate cumulative voting in the election of directors. Some provisions of
Delaware law applicable to us could also delay or make more difficult a merger,
tender offer or proxy contest involving us, including Section 203, which
prohibits a Delaware corporation from engaging in any business combination with
any interested stockholder for a period of three years unless certain
conditions are met. Our stockholder rights plan, the

                                       16
<PAGE>

possible issuance of preferred stock, the procedures required for director
nominations and stockholder proposals and Delaware law could have the effect of
delaying, deferring or preventing a change in control of ArthroCare, including
without limitation, discouraging a proxy contest or making more difficult the
acquisition of a substantial block of our common stock. For a description of
our certificate of incorporation, bylaws and stockholder rights plan, see
"Description of Capital Stock."

Future Sales By Current Stockholders Could Cause Our Common Stock Price to
Decline

   The market price of our common stock could decline as a result of sales of a
large number of shares in the market after this offering or the perception that
such sales could occur. These sales could also make it more difficult for us to
sell equity securities in the future at a time and at a price that we deem
appropriate to raise funds through future offerings of common stock.

We Face Uncertainty With Year 2000 Compliance

   We rely on computers and computer software to run our business, as do our
vendors, suppliers and customers. These computers and this computer software
may not be able to properly recognize the dates commencing in the Year 2000. We
have assigned a task force to handle the significant uncertainty that exists
concerning the potential effects associated with Year 2000 compliance. The task
force has formulated and begun to implement a plan to address Year 2000
compliance including the formulation of contingency plans. To date, we have not
found a material impact that may result from the failure of our computers and
computer software or that of our vendors, suppliers, and customers to recognize
dates. We have completed an upgrade of our information technology system
including our financial system, order processing, manufacturing and inventory
system which included Year 2000 compliance. We have not yet completed the steps
to quantify the effects of noncompliance of our customers, suppliers and/or our
service providers. Our goal is to complete all phases of our review and be Year
2000 compliant by December 1999.

   Any Year 2000 compliance problem affecting us, our suppliers, our service
providers or our customers could result in a material adverse effect on our
financial condition, results of operations and future growth prospects. We
cannot assure you that further assessment of our suppliers, data processing
systems or contingency plans will address all issues of Year 2000 compliance.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

   Some statements contained in this prospectus including, without limitation,
statements containing the words "believes," "anticipates," "expects" and words
of similar meaning, constitute "forward-looking statements" within the meaning
of the Private Securities Litigation Reform Act of 1995, or the Reform Act.
These forward-looking statements involve known and unknown risks, uncertainties
and other factors which may cause our actual results, performance or
achievements, or industry results, to be materially different from any future
results, performance or achievements expressed or implied by these forward-
looking statements. These factors include, among others:

  . our inability to manage our growth and successfully launch our products
    and expand in new and existing markets;

  . market acceptance of, and the level of demand for, our products;

  . compliance with government standards and the obtaining of necessary
    approvals;

  . changes in general economic and business conditions;

  . changes in our business strategies; and

  . other factors referenced in this prospectus.

   Some of these factors are discussed in more detail elsewhere in this
prospectus, including, without limitation, under the captions "Summary," "Risk
Factors," "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and "Business." Given these uncertainties, you should

                                USE OF PROCEEDS

   The net proceeds to us from the sale of the 1,000,000 shares of common stock
offered in this sale at an assumed public offering price of $53.00 per share
are estimated to be approximately $49.3 million ($56.8 million assuming the
underwriter's over-allotment option is exercised in full), after deducting the
underwriting discounts and commissions and estimated offering expenses payable
by us.

   We anticipate using the net proceeds from this offering as follows:
approximately $15.0 million for sales, marketing and development efforts
associated with the commercialization of our spinal surgery product line and
the balance to fund the development, commercialization and associated working
capital requirements of applying our Coblation technology to a broad range of
other soft-tissue markets and for corporate and other general purposes.

   Although we expect to incur expenditures for the above-mentioned activities,
we have not made specific allocations of the offering proceeds. Further, we
cannot assure you that commercial introduction of the spinal surgery products
will be successfully completed or that we will not exceed current spending
expectations. Although we may use a portion of the net proceeds to acquire new
products or technologies from others as well as to continue enforcing our
patent position, we currently do not have specific plans or commitments in this
regard. The amount and timing of our expenditures may vary depending upon
numerous factors, including market acceptance of our current and future
products, the timing of regulatory actions on our products and results of
clinical trials. Pending uses such as these, we intend to invest the net
proceeds in short-term, investment-grade, interest-bearing securities.

                                DIVIDEND POLICY

   We have never declared nor paid cash dividends on our capital stock. We
currently expect to retain our future earnings, if any, for use in the
operation and expansion of our business and do not anticipate paying any cash
dividends in the foreseeable future. Our loan and security agreement prohibits
the payment of dividends without the consent of the lender.

                                    DILUTION

   Purchasers of the common stock offered hereby will experience immediate and
substantial dilution in the net tangible book value per share of their common
stock. At July 3, 1999, our net tangible book value was approximately $24.6
million, or $2.72 per share of common stock. The net tangible book value per
share is equal to our total tangible assets less total liabilities, divided by
the number of shares of common stock outstanding at July 3, 1999. After giving
effect to the sale of 1,000,000 shares at an assumed public offering price of
$53.00 per share and after deducting underwriting discounts and commissions,
our net tangible book value at July 3, 1999 would have been approximately $73.9
million, or $7.36 per share. This represents the immediate increase in pro
forma net tangible book value of $4.64 per share to existing stockholders and
an immediate dilution of $45.64 per share to new investors purchasing shares of
common stock in this offering. Dilution to new investors is determined by
subtracting pro forma net tangible book value per share of common stock after
giving effect to this offering, from the price to be paid by new investors in
this offering for a share of common stock. The following table illustrates the
per share dilution to investors in this offering:

</TABLE>

   The discussion and table above assumes no exercise of any stock options and
warrants after July 3, 1999. As of July 3, 1999 there were 1,611,283 shares of
common stock issuable upon exercise of options outstanding at a weighted
average exercise price of $11.89 per share, and warrants to purchase 80,000 and
40,000 shares of our common stock at purchase prices of $12.00 per share and
$14.00 per share, respectively. To the extent that any of these options or
warrants are exercised, there will be further dilution to new investors.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITIONS AND RESULTS OF OPERATIONS

   The following discussion should be read in conjunction with the consolidated
financial statements and notes thereto appearing elsewhere in this prospectus.
Statements in this Management's Discussion and Analysis of Financial Condition
and Results of Operations which express that we "believe," "anticipate,"
"expect" or "plan to" as well as other statements which are not historical
fact, are forward-looking statements within the meaning of the Private
Securities Litigation Reform Act of 1995. Actual events or results may differ
materially as a result of the risks and uncertainties described herein and
elsewhere including, but not limited to, those factors discussed in "Risk
Factors" and elsewhere in the prospectus.

Overview

   We are a medical device company that develops, manufactures and markets
products based on our patented Coblation technology. Our products allow
surgeons to operate with increased precision and accuracy, limiting damage to
surrounding tissue thereby reducing pain and speeding recovery for the patient.
Our products operate at lower temperatures than traditional electrosurgical or
laser surgery tools and enable surgeons to ablate or shrink soft tissue and to
simultaneously seal bleeding vessels. Our soft-tissue surgery systems consist
of a controller unit and an assortment of disposable devices that are
specialized for specific types of surgery. We believe our Coblation technology
can replace the multiple surgical tools traditionally used in soft-tissue
surgery procedures with one multi-purpose surgical system.

   Coblation technology is applicable across many soft-tissue surgical markets.
Our systems are used to perform many types of arthroscopic surgery. Our
strategy includes applying our patented Coblation technology to a broad range
of other soft-tissue markets, including cosmetic surgery, ENT surgery, spinal
surgery and various cardiology applications.

   In April 1998, we announced that we had entered the cosmetic surgery market
and formed a business unit called Visage to commercialize Coblation technology
in this field. In early 1999, we entered into a license and distribution
agreement with Collagen Aesthetics, Inc. Under this agreement, Collagen
Aesthetics, Inc. acquired exclusive, worldwide, marketing rights for our
cosmetic surgery line of products for the dermatology and cosmetic surgery
markets.

   In May 1998, we announced that we had entered the ear, nose and throat
market and had formed a business unit called ENTec to commercialize Coblation
technology in this field. In June 1998, we entered into a license agreement
with Xomed Surgical Products, Inc. to market Coblation products in the ear,
nose and throat market. In February 1999, Xomed filed a suit against us
alleging breach of contract and seeking monetary damages. We then terminated
this agreement and have been marketing and selling the ENT surgery product line
through a network of distributors supported by regional sales managers.

   In September 1999, we announced the introduction of a new product line using
Coblation technology for spinal surgery.

   In early 1998, we formed a business unit, AngioCare, for the purpose of
further developing and for commercializing our technology in specific
applications in the field of cardiology. As part of those efforts, in February
1998, we entered into a license agreement under which Boston Scientific
Corporation will help develop, obtain regulatory approval for and market
products based on Coblation technology for myocardial revascularization
procedures.

   We have received 510(k) clearance to market our Arthroscopic System for use
in arthroscopic surgery of the knee, shoulder, ankle, elbow, wrist and hip, and
our Arthroscopic System is CE marked for use in arthroscopic surgery. Our
Cosmetic Surgery System is CE marked for general dermatology, skin resurfacing
and wrinkle reduction procedures and we have received 510(k) clearance for use
of our Cosmetic Surgery System in general dermatology procedures in the United
States. We are pursuing additional clearances that will

                                       24
<PAGE>

allow our Cosmetic Surgery System to be marketed in the United States
specifically for skin resurfacing and wrinkle reduction. Our ENT surgery system
is CE marked, and we have received 510(k) clearances for use of our ENT surgery
system in general head, neck, oral and sinus surgery procedures in the United
States. Our Spinal Surgery System is CE marked and we have applied for 510(k)
clearance in the United States to market this system for spinal surgery. We
have received 510(k) clearance to market Coblation technology for general
surgery.

   In December 1995, we introduced our Arthroscopic System commercially in the
United States. Our strategy includes placing controller units, at substantial
discounts, to generate future disposable revenue. Our strategy also includes
applying our patented Coblation technology to a range of other soft-tissue
surgical markets including the products we have introduced in the fields of
spinal surgery, cosmetic surgery and ear, nose and throat surgery. We have
received 510(k) clearance for use of our technology in several fields. We
cannot be sure that any of our clinical studies in other fields will lead to
510(k) applications or that the applications will be cleared by the FDA on a
timely basis, if at all. In addition, we cannot be sure that the products, if
cleared for marketing, will ever achieve commercial acceptance.

</TABLE>

Six Months Ended July 3, 1999 and July 4, 1998

 Revenues

   Product sales for the six months ended July 3, 1999 were $19.2 million,
representing an 82% increase, from $10.5 million for the same period of the
prior year. The increase in product sales resulted primarily from an increase
in the sales of both controllers and disposable devices. The higher unit volume
of sales resulted primarily from increased activity for newly introduced models
of disposable devices for arthroscopy and sales of disposable devices of new
product lines.

   International product sales for the six months ended July 3, 1999 increased
to 11% compared to 9% of product sales for the same period in 1998. The
increase in international sales is primarily attributable to increased sales in
the Pacific Rim, as we received regulatory approval to market arthroscopic
products in Japan, and to increased sales in Europe.

   Our strategy in arthroscopy has been, and continues to be, to increase
future disposable device sales by increasing the installed base of controllers
through promotional programs. Disposable devices are consistently sold at or
near list price, except for sales to international distributors and marketing
partners, which are currently sold at discounted prices. We expect these
discounts to continue in the future. Based on the estimated number of
procedures performed each year, we believe that knee procedures represent the
largest segment of the arthroscopic market. To achieve increasing disposable
device sales in arthroscopy over time, we believe we must continue to penetrate
the market in knee procedures, expand physicians' education with respect to
Coblation technology and continue to work on new product development efforts
specifically for knee

applications. During the second half of fiscal year 1998, we introduced new
disposable devices, including the Saber and CoVac, which are designed primarily
to be used in arthroscopic knee procedures. We expect disposable device sales
to remain the primary component of product sales in the future.

   License fees and royalties increased to $2.8 million for the six months
ended July 3, 1999 from $2.6 million for the six months ended July 4, 1998. The
increase is primarily due to the timing of license fees received as the result
of settlement of a patent infringement suit initiated by us against Ethicon,
Inc. partially offset by the timing of license fees received from our business
partners in the prior year. In February 1998, we entered into a license
agreement under which Boston Scientific Corporation was granted an exclusive
right to develop and market products based on Coblation technology for
myocardial revascularization procedures. Boston Scientific Corporation pays
license fees (a portion of which will be classified as prepaid royalties) to us
upon achievement of designated milestones and royalties on sales of resulting
products, if any. During the six-month period ending July 3, 1999 we recognized
$0.3 million of such payments as license fees and royalties. We received a
license payment from Boston Scientific Corporation of $3.0 million in February
1998 of which $2.3 million was recognized as revenue during the six-month
period ended July 4, 1998. In January 1999, we entered into a license and
distribution agreement with Collagen Aesthetics, Inc., which was expanded in
February 1999, whereby Collagen Aesthetics, Inc. acquired exclusive, worldwide,
marketing rights for our patented Coblation technology in the cosmetic surgery
market. Under the terms of the agreement, Collagen Aesthetics, Inc. pays us
license fees based upon the achievement of certain milestones and royalties on
sales of product to end-users. During the six-month period ended July 3, 1999,
we recognized $1.0 million of these payments as license fees and royalties.

 Cost of Product Sales

   Cost of product sales for the six months ended July 3, 1999 was $8.2 million
or 43% of product sales, as compared with $6.0 million or 57% of product sales
for the same period of the prior year. The increase in cost of product sales in
absolute dollars is attributable to increasing unit sales of both controllers
and disposable devices. The decrease in cost of product sales as a percentage
of product sales is attributable to increased manufacturing efficiency and
increased production volume. In addition, we continued controller placements
under a program whereby we maintain ownership of the controller, which resulted
in the cost being capitalized and amortized over future periods rather than
expensing the entire cost at the time of placement.

   We cannot be sure that cost of product sales as a percentage of product
sales will remain at current levels or show improvement in the future due to
the distribution channels used, product mix, and fluctuation in manufacturing
production levels as new products are introduced. We believe our gross margin
will depend upon the mix of disposable device sales versus controller sales
and/or placements and the various distribution channels utilized to sell our
products in all commercialized fields. There can be no assurance that we will
be successful in maintaining the mix of disposable devices to controllers or in
increasing demand for our disposable devices. In addition, production of future
products, inefficiencies in manufacturing new products and the distribution
channels utilized to sell those products may adversely impact gross margin.

 Operating Expenses

   Research and development expense for the six months ended July 3, 1999, and
July 4, 1998, was $2.2 million and $2.1 million, respectively. In general,
overall spending in research and development increased slightly as we continued
to develop new products. Increases in research and development expense have
been partially offset by funding received from business partners for continued
product development. We believe that investment in our Coblation technology is
essential for us to maintain our competitive position. We expect to increase
the dollar amount of research and development spending through continued
expenditures on new product development, regulatory affairs, clinical studies
and patents, but anticipate expenses to continue to decrease as a percentage of
product sales.

   Sales and marketing expense for the six months ended July 3, 1999, increased
to $7.1 million or 37% of product sales from $4.5 million or 43% of product
sales for the same period of the prior year. The increase in

                                       26
<PAGE>

spending in absolute dollars resulted primarily from higher dealer commissions
resulting from increased sales, increased staffing and increased trade-show
related expense. We also incurred additional sales and marketing expenses
during the current-year period as we expanded operations in Europe.

   We anticipate that sales and marketing spending will continue to increase in
absolute dollars due to expansion of our distribution capabilities to address
the spinal surgery market, higher dealer commissions from increased sales, the
additional cost of penetrating international markets, higher promotional,
demonstration and sample expenses, and additional investments in the sales,
marketing and support staff necessary to market our current products and to
commercialize future products.

   For the six months ended July 3, 1999, and July 4, 1998, general and
administrative expense increased to $3.0 million, or 16% of product sales, from
$1.9 million or 18% of product sales, respectively. Overall, the most
significant increase was attributable to legal expenses related to the patent
infringement claims we brought against Ethicon. We expect that general and
administrative expenses will decrease as a result of the recent settlement of
this litigation, offset partially by an increase in additional business
development activities.

 Interest and Other Income, net

   Interest and other income, net decreased to $0.2 million in the current-year
period from $0.6 million in the comparable prior year period. The decrease
resulted primarily from a decrease in interest income from investments due to
the declining balance of cash and investments.

 Income Tax Provision

   The provision for income taxes was $65,000 for the six-month period ended
July 3, 1999, and was zero in the prior year period. Because we use net
operating loss carryforwards generated in prior years, our tax rate is below
the statutory rate. We have federal net operating loss carryforwards which
expire in the years 2004 through 2018, and state net operating loss
carryforwards which expire in the years 2000 through 2003. We are subject to
certain alternative minimum tax requirements in the current year for which an
estimate is made based on the anticipated effective tax rate at the end of the
fiscal year.

 Net Income (Loss)

   For the six months ended July 3, 1999, net income increased to $1.5 million
from a net loss of $0.8 million for the same period of the prior year. Net
income for the current period reflects an increase in product sales, license
fees and gross margin partially offset by increased spending in sales and
marketing and legal expenses. Although we have experienced substantial revenue
growth since inception and have been profitable on a quarterly basis since the
quarter ended April 3, 1999, due to our short operating history and numerous
other factors, we cannot be sure that we can sustain revenue growth or
profitability.

Years Ended January 2, 1999, January 3, 1998 and December 28, 1996

 Revenues

   Total revenue for the year ended January 2, 1999 was $27.9 million compared
to $12.8 million for the year ended January 3,1998 and $6.0 million for the
year ended December 28, 1996. Increases year-over-year were due to higher unit
volume sales of disposable devices resulting from continued controller
placement programs and a larger installed base of controllers along with
revenues received from licensing arrangements with corporate partners.

   Substantially all revenue was derived domestically and from the sale of
disposable devices during these periods. We attribute increased disposable
device sales to our strategic plan to build market share in arthroscopy through
continued promotional programs of controllers.

                                       27
<PAGE>

   We received a nonrefundable license fee payment of $3.0 million from Boston
Scientific Corporation during the first quarter of 1998 of which $2.6 million
was recognized as license fee revenue during the year. During this period we
also recognized $0.4 million of license fees from Xomed and $0.3 million of
license fees from Collagen Aesthetics, Inc.

 Cost of Product Sales

   Cost of product sales for the year ended January 2, 1999 was $12.4 million
or 50% of product sales, as compared to $8.5 million, or 66% of product sales
for the year ended January 3, 1998. During the year ended December 28, 1996,
cost of product sales was $5.2 million, or 87% of product sales. The $3.9
million increase in cost of product sales for the year ended January 2, 1999
over the year ended January 3, 1998 and the $7.2 million increase over the year
ended December 28, 1996 were due to increased shipments of both disposable
devices and controllers.

   Cost of product sales as a percentage of product sales decreased 16
percentage points during the year ended January 2, 1999 as compared to the
previous year and 37 percentage points as compared to the year ended December
28, 1996. The overall decrease in cost of product sales as a percentage of
product sales resulted from fixed and semi-fixed costs being spread over higher
manufacturing volumes, improvements to the manufacturing process and various
controller promotional programs.

   In 1997 we began manufacturing our controllers in-house. We believe that
manufacturing our controllers in-house provided a positive impact to gross
margins during the year ended January 2, 1999.

 Operating Expenses

   Research and development expense increased 8% to $4.4 million in 1998, from
$4.0 million in 1997, and increased 7% in 1997, from $3.8 million in 1996. The
$0.4 million and $0.2 million increases in spending between 1998 and 1997 and
between 1997 and 1996, respectively, are attributed primarily to the
development and introduction of new disposable devices, the development of
products for additional markets, patent filings and increased clinical
expenses. The increases were partially offset by a reduction of quality
assurance expenses related to research and development during the year ended
January 2, 1999, as quality assurance activities now primarily relate to
manufacturing efforts rather than research and development efforts, and to
reimbursement of expenses by our business partners for some research and
development activities.

   Sales and marketing expense increased to $10.5 million or 68% in 1998, from
$6.3 million in 1997, and increased 72% in 1997 from $3.6 million in 1996. The
$4.2 million and $2.6 million increases between 1998 and 1997, and 1997 and
1996, were primarily due to higher dealer commissions resulting from increased
sales, higher staffing expenses including the establishment of a European
headquarters, and promotional and trade show expenses reflecting an increased
level of sales and marketing activity.

   General and administrative expense increased to $3.8 million or 21% in 1998,
from $3.1 million during 1997, and increased 21% in 1997, as compared to $2.6
million in 1996. The $0.7 million increase for the year ended January 2, 1999
over the year ended January 3, 1998 is primarily due to expenses we incurred in
association with the patent litigation we brought against Ethicon, Inc. and
increased staffing, partially offset by the expense, in the prior year, of
attracting, recruiting and relocating our chief executive officer. The $0.5
million increase in 1997, over 1996 resulted primarily from the increased cost
of general legal service, business development activities, increased staffing,
insurance and expenses necessary to expand the corporate infrastructure.

 Interest and Other Income, net

   Interest income and other, net decreased for the year ended January 2, 1999
to $0.9 million from $1.4 million for the year ended January 3, 1998 and from
$1.5 million for the year ended December 28, 1996. The $0.5 million decrease in
the most recently completed period was attributable to the conversion of
investments to

                                       28
<PAGE>

cash for use in business operations during the year resulting in a lower
balance of investment on which to earn interest income. At the end of fiscal
1998, we had $8.1 million in cash, cash equivalents, and available-for-sale
securities as compared to $19.9 million at the end of fiscal 1997 and $29.3
million at the end of fiscal 1996.

 Net Loss

   Net loss decreased significantly to $2.1 million for the year ended January
2, 1999, from $7.7 million for each of the years ended January 3, 1998 and
December 28, 1996. The overall decrease in net loss was primarily due to an
overall improvement in our operating position. Specifically, we experienced a
significant increase in sales with an improvement in gross margin and reduced
costs associated with research and development, sales and marketing, and
general and administrative expenses as a percentage of revenues. License
payments received from our business partners also contributed to the reduced
net loss.

Liquidity and Capital Resources

   On July 3, 1999, we had $17.6 million in working capital. The principal
source of liquidity consisted of $7.1 million in cash, cash equivalents and
available-for-sale securities. The cash and cash equivalents are highly liquid
with original maturities of 90 days or less. In addition, we have a $7.0
million line of credit. Available borrowings under this line of credit are
contingent upon and collateralized by some of our asset balances and are
subject to covenants related to financial ratios and profits. Borrowings under
the line of credit bear interest at the bank's prime rate plus one-quarter of
one percentage point. At July 3, 1999, we were in compliance with these
covenants and had no outstanding borrowings.

   Net cash provided by operating activities for the six months ended July 3,
1999 was $1.2 million. Cash used in operating activities for the six months
ended July 4, 1998 was $1.8 million. The increase in cash provided by operating
activities year-over-year was primarily due to the net income of $1.5 million
for 1999 compared to a net loss in 1998 of $0.8 million, and an increase in the
depreciation amounts year-over-year.

   Net accounts receivable increased to $7.4 million as of July 3, 1999 from
$6.0 million as of January 2, 1999. The increase in accounts receivable is
mainly attributable to the corresponding increase in product sales offset in
part by a decrease in the overall number of days sales outstanding.

   Inventories increased slightly to $7.6 million as of July 3, 1999 from $7.1
million at January 2, 1999, due to the need to support higher anticipated
product sales activity. We expect future inventory levels to grow to support
sales volume increases, as a result of our expansion into the markets of spinal
surgery, ear, nose and throat surgery and cosmetic surgery.

   Net property and equipment increased to $5.7 million as of July 3, 1999 from
$4.6 million on January 2, 1999. The increase is primarily attributable to the
capitalization of controllers placed under various promotional programs along
with an increase of computer software and equipment.

   Our proceeds from the sale of the 1,000,000 shares of common stock we are
offering are estimated to be $49.3 million ($56.8 million if the underwriters'
over-allotment option is exercised in full) after deducting the underwriting
discounts and commissions and our estimated offering expenses. We believe that
the proceeds from this offering, together with our current cash balances, cash
equivalents, short-term investments and cash generated from our collaborative
arrangements will be sufficient to meet our operating and capital requirements
through the end of 2000. As of July 3, 1999, we had committed to capital
expenditures of approximately $0.3 million. Our future liquidity and capital
requirements will depend on numerous factors, including our success in
commercializing our products, development and commercialization of products in
fields other than arthroscopy, the ability of our suppliers to continue to meet
our demands at current prices, obtaining and enforcing patents important to our
business, the status of regulatory approvals and competition.

   As of July 3, 1999, we had federal net operating loss carryforwards of
approximately $15.0 million. The net operating loss carryforwards will expire
in the years 2004 through 2018, if not utilized.

Recent Operating Results

   On October 7, 1999, we announced operating results for the quarter ended
October 2, 1999. A summary of such announcement is set forth in the paragraph
below containing certain preliminary unaudited financial data for the quarter
ended October 2, 1999. Our operating results for any one quarter are not
necessarily indicative of future results of operations and should be read in
conjunction with the audited consolidated financial statements and the notes
thereto included elsewhere in this prospectus.

   Total revenue for the third quarter of 1999 was $12.3 million, an increase
of 78% over total revenue of $6.9 million reported for the comparable period of
1998. In addition, we reported net income of $1.2 million for the third quarter
of 1999, compared to a net loss of $1.1 million for the comparable period in
1998. For the nine-month period ended October 2, 1999, we reported product
sales of $30.7 million and total revenue of $34.2 million. In the comparable
period of 1998, product sales and total revenue were $17.3 million and $20.1
million, respectively. Net income was $2.7 million for the first nine months of
1999 compared with a net loss of $1.9 million in the first nine months of 1998.


Year 2000

   We rely on computers and computer software to run our business, as do our
vendors, suppliers and customers. These computers and computer software may not
be able to properly recognize the dates commencing in the Year 2000. We have
assigned a task force to handle the significant uncertainty that exists
concerning the potential effects associated with Year 2000 compliance. The task
force has formulated and begun to implement a plan to address Year 2000
compliance, including the formulation of contingency plans. To date, we have
not found a material impact that may result from the failure of our computers
and computer software, or that of our vendors, suppliers, and customers, to
recognize dates. We have completed an upgrade of our information technology
system, including our financial, order processing, manufacturing and inventory
systems, which included Year 2000 compliance. To date we have spent
approximately $900,000 upgrading our computer system and related technology. We
have not yet completed the steps to quantify the effects of noncompliance of
our customers, suppliers and/or our service providers. Our goal is to complete
all phases of our review and be Year 2000 compliant by December 1999.

   Any Year 2000 compliance problems affecting us, our suppliers, our service
providers or our customers could result in a material adverse effect on our
financial condition and operating results. We cannot be sure that further
assessment of our suppliers, data processing systems or contingency plans will
address all issues of Year 2000 compliance.

Recent Accounting Pronouncements

   In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities." SFAS No. 133 establishes accounting and reporting
standards for derivative instruments, including certain derivative instruments
embedded in other contracts, and for hedging activities. It requires that an
entity recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those instruments at fair value. We
must adopt this standard no later than fiscal year 2001. To date, we do not
engage in hedging activities.

Market Risk

   We have an investment portfolio of fixed income securities that are
classified as "available-for-sale securities." These securities, like all fixed
income instruments, are subject to interest rate risk and will fall in value if
market interest rates increase. We attempt to limit this exposure by investing
primarily in short-term securities.

                                    BUSINESS

Overview

   We are a medical device company that develops, manufactures and markets
products based on our patented Coblation technology. Our products allow
surgeons to operate with increased precision and accuracy, limiting damage to
surrounding tissue thereby reducing pain and speeding recovery for the patient.
Our products operate at lower temperatures than traditional electrosurgical or
laser surgery tools and enable surgeons to ablate or shrink soft tissue and to
simultaneously seal bleeding vessels. Our soft-tissue surgery systems consist
of a controller unit and an assortment of disposable devices that are
specialized for specific types of surgery. We believe our Coblation technology
can replace the multiple surgical tools traditionally used in soft-tissue
surgery procedures with one multi-purpose surgical system.

   Coblation technology is applicable across many soft-tissue surgical markets.
Our systems are used to perform many types of arthroscopic surgery. Our
strategy includes applying our patented Coblation technology to a broad range
of other soft-tissue markets, including cosmetic surgery, ENT surgery, spinal
surgery and various cardiology applications.

ArthroCare Strategy

   Our objective is to use our patented Coblation technology to design,
develop, manufacture and sell innovative, clinically superior surgical devices
for the arthroscopic surgical treatment of joint injuries and for the surgical
treatment of other soft-tissue conditions throughout the body. The key elements
of our strategy include:

  . EXPANDING OUR PRODUCT OFFERING TO ADDRESS A LARGER NUMBER OF ARTHROSCOPIC
    PROCEDURES. We are continuously expanding our portfolio of products in
    arthroscopy by enhancing our existing products to serve the needs of
    physicians. For example, we have increased our penetration of arthroscopy
    procedures in the knee through the addition of disposable devices with
    suction capability.

  . EXPANDING INTO ADDITIONAL SURGICAL MARKETS. Our systems are being used to
    perform many types of arthroscopic surgery and also have been cleared for
    use in certain types of cosmetic surgery and ENT surgery. In addition, we
    have introduced our systems for use in the spinal surgery market and
    anticipate FDA clearance by the end of 1999. We are developing our
    Coblation technology for use in myocardial revascularization, a
    cardiology procedure, with our partner, Boston Scientific Corporation.

  . EXPANDING INTERNATIONAL PRESENCE. We have established an extensive
    distributor network, supported by our regional managers, in selected
    international markets. We have signed agreements with several marketing
    partners to assist with regulatory requirements and to market and
    distribute our products internationally.

  . STRUCTURING FLEXIBLE STRATEGIES TO COMMERCIALIZE OUR COBLATION
    TECHNOLOGY. We have chosen to adopt a customized distribution strategy to
    optimize our commercialization efforts in each of our target markets. In
    arthroscopy and ENT surgery, we utilize distributor relationships
    supported by focused regional managers and a small direct sales force. In
    the spinal surgery market, we will leverage our existing distributors,
    add new distributors focused on spinal products, and increase the number
    of our direct sales managers to support these distributors. In cosmetic
    surgery, we have chosen to partner with a leading cosmetic surgery
    company, Collagen Aesthetics, Inc. We have chosen to partner with Boston
    Scientific Corporation to further develop and to commercialize our
    technology in the myocardial revascularization application of cardiology.

Coblation Technology

   Our products are based on our patented soft-tissue surgical controlled
ablation technology, which we call Coblation. Coblation technology involves an
innovative use of radio frequency energy characterized by precision, accuracy,
ease of use and the capability of performing at a temperature lower than
current traditional electrosurgical tools.

   Traditional electrosurgical tools rely upon heat to burn away targeted
tissue, which often results in thermal damage to tissue surrounding the
surgical area. Additionally, the lack of tactile feedback with these devices
makes it difficult for surgeons to control the depth of tissue penetration.
Coblation technology employs a lower temperature process that minimizes the
risk of thermal burn of tissue while increasing the surgeon's control and
precision.

   Coblation technology uses an electrically conductive fluid typically
employed in surgeries, in the gap between the electrode and tissue. When
electrical current is applied to this fluid, it creates a charged layer of
particles. As the layer of charged particles comes into contact with the
targeted tissue, the molecular bonds within the cells of the targeted tissue
are broken. This process causes the cells to disintegrate molecule by molecule,
so that tissue is volumetrically removed. Because this effect is confined to
the surface layer of the targeted tissue, minimal damage occurs to surrounding
tissue, potentially resulting in reduced pain and faster recovery for the
patient. An additional advantage is that Coblation can be performed in a
continuous mode, resulting in efficient tissue ablation thereby reducing the
overall procedure time as compared to conventional methods. In addition to
achieving more precise tissue ablation or shrinkage and less damage to
surrounding tissue, surgical devices based on Coblation technology can achieve
simultaneous sealing of bleeding vessels near the surgical site.

   We believe Coblation technology is applicable to soft-tissue surgery
throughout the body, and we have expanded its use into several non-arthroscopic
indications. In addition, we are continually exploring possibilities for the
use of Coblation technology in other markets.

The Arthroscopy Market

   In 1998, approximately 2.3 million arthroscopic procedures were performed in
the United States. Due to patient demand for less invasive procedures, we
believe the number of arthroscopic procedures is growing. In addition, a
greater emphasis on physical fitness and an aging population is increasing the
incidence of joint injuries. Joints are susceptible to injuries from blows,
falls or twisting, as well as from natural deterioration and stiffening
associated with aging.

   Historically, joint injuries have been treated using open surgery involving
large incisions, a hospital stay and a prolonged recovery period. In contrast,
arthroscopic surgery, which was introduced in the early 1980s, is performed
through several small incisions called portals and can be performed on an
outpatient basis. We believe that arthroscopic surgery has gained wide market
acceptance because it offers shorter hospital stays and reduced recovery time,
resulting in reduced costs and improved medical outcomes.

   To perform arthroscopic surgery, a surgeon uses a tool to visualize the site
and other tools to perform the surgery. The tool used to visualize the site,
called an arthroscope, is a small fiber-optic viewing instrument made up of a
small lens, a light source and a video camera, which allows the surgeon to view
the surgical procedure on a video monitor. During the arthroscopic procedure,
an irrigant such as saline is flushed through the joint to permit clear
visualization through the arthroscope and to create the space within the joint
for the surgical procedure. The surgeon inserts the arthroscope into the joint
through a portal measuring approximately six millimeters, or 1/4 of an inch, in
length. Other portals are used for the insertion of surgical instruments to
perform the surgery and to facilitate the flow of irrigants. With small
incision sites and direct access to most areas of the joint, a surgeon can
diagnose and correct an array of joint problems such as cartilage tears,
ligament tears and removal of loose and degenerative tissue.

                                       32
<PAGE>

   The advantages of arthroscopic surgery over open surgery are often
significant. Due to the smaller incisions and reduced surgical trauma, the
patient might experience several benefits including reduced pain; treatment on
an outpatient basis; reduced or eliminated hospitalization times; immediate
joint mobility and less muscle atrophy; less surrounding tissue damage; lower
rate of complications; and generally quicker rehabilitation. In addition,
treatment on an outpatient basis and reduced operating time can significantly
lower hospital costs.

 Knee

   The knee is the most commonly injured joint. In 1998, knee injuries
accounted for approximately 1.5 million arthroscopic procedures in the United
States. Damage to a meniscus, a pad of cartilage that helps cushion the knee
joint, is a common form of knee injury. A meniscus can be torn by a twist of
the leg when the knee is flexed, displaced either inward toward the center of
the shin bone or outward beyond the surface of the thighbone, or worn down by
normal aging. The knee is also susceptible to partial or complete tears of the
ligaments and degeneration of the cartilage on the underside of the kneecap. In
addition, the cartilage covering the bony surfaces of the knee can become rough
or tear loose from the bone as a result of age or injury, causing pain and
interfering with smooth joint movement.

 Shoulder

   The shoulder joint, because of its range of motion, is susceptible to a
number of injuries. In 1998, approximately 600,000 arthroscopic procedures in
the shoulder were performed in the United States. We believe that shoulder
arthroscopy is the fastest-growing portion of the arthroscopy market. With
repetitive motion and lifting of the arm, such as that which occurs during a
tennis serve, a bone formation of the upper arm may pinch one of the shoulder
muscles and cause persistent pain, known as a rotator cuff injury.
Strengthening exercises and physiotherapy can treat this condition; however,
many rotator cuff injuries require surgical intervention. We believe that a
significant percentage of the population is born with a susceptibility to
rotator cuff injuries.

 Elbow, Ankle, Wrist and Hip

   The elbow, ankle, wrist and hip joints are also susceptible to certain
stress-related injuries and deterioration due to aging. In 1998, approximately
200,000 arthroscopic procedures were performed in the elbow, ankle, wrist and
hip in the United States. We believe that the current number of surgical
procedures in the elbow, ankle, wrist and hip is relatively small due to the
limitations of conventional arthroscopic surgical equipment.

Conventional Treatment Methodologies for Arthroscopic Procedures

   Most arthroscopic procedures require the surgeon to probe, cut, sculpt and
shape tissue and seal bleeding vessels to achieve satisfactory results.
Surgeons frequently use a combination of instruments when performing an
arthroscopic procedure because each instrument is designed to perform a
specific function. Use of an assortment of tools requires the surgeon to insert
and remove each of the tools from the portals several times during the same
procedure.

   Surgical procedures can employ one or more of four groups of surgical
instruments: (1) power or motorized instruments, such as cartilage and bone
shavers; (2) mechanical instruments, such as basket punches, graspers and
scissors; (3) electrosurgical systems; or (4) laser systems.

   Power instruments are generally used to smooth tissue and cartilage defects
on the surface of the bones of the joint. The damaged tissue is removed from
the joint using suction through a tube surrounding the shaft of the tool, which
can become obstructed by bits of tissue and bone. Power shavers have rotating
cutters inside a tube and are available in a number of tip angles or sizes for
the precise shaving of tissue. Mechanical tools must be resharpened at regular
intervals and sterilized after each procedure.


                                       33

   Conventional electrosurgical systems are used to seal blood vessels, which
is necessary to minimize bleeding and maximize the arthroscopic surgeon's
visibility of the procedure through the arthroscope. Conventional
electrosurgical systems contain two electrodes: the electrode tip held by the
surgeon and a dispersive pad that rests under the patient's body. The metal
electrode tip of the instrument, which resembles a pencil point, is placed on
or near the bleeding vessel to be sealed. A generator connected to the
electrode delivers high-frequency voltage that arcs between the electrode and
the target tissue, sealing blood vessels in its vicinity. After arcing, the
current travels through the remaining tissue of the patient's body, through the
skin to the dispersive electrode pad, before being directed back to the
generator.

   Laser systems are used to remove tissue while simultaneously sealing
bleeding vessels. Because laser systems are not tactile tools, the surgeon
cannot feel how much tissue is being ablated. The surgeon must be extensively
trained to precisely position the laser to control the depth of tissue
penetration to minimize unintended tissue damage. In addition, the temperature
of the laser instrument is high and, as a result, can cause damage to
surrounding tissue and vascular areas. We believe that laser tools have not
received wide acceptance because of high capital cost and significant ongoing
maintenance and operating expenses, lack of tactile feedback for the surgeon,
required training and certification, and the concern about damage that may be
caused by the significant heat generated by these devices.

The ArthroCare Arthroscopic System

   Our Arthroscopic System is a radio frequency surgical device intended to
perform tissue ablation or shrinkage while simultaneously sealing bleeding
vessels. Our Arthroscopic System is comprised of an assortment of disposable
bipolar multi-electrode and single electrode devices, a connecting cable, foot
pedal or switch and a radio frequency controller. We sell our Arthroscopic
System for use in all six major joints: knee, shoulder, elbow, ankle, wrist and
hip. Many types of tissue, including cartilage and ligaments, can be ablated
using our Arthroscopic System.

   Our controller delivers radio frequency energy to the disposable device.
Surgeons can use the disposable device to ablate or shrink tissue or seal
bleeding vessels. The surgeon can control the mode of operation and power
setting with the foot pedal or keys on the front panel of the controller.

   Accordingly, a surgeon using the Arthroscopic System does not need to remove
and insert a variety of instruments to perform different tasks as is required
when using conventional arthroscopic instruments. Our disposable devices are
approved for sale in tip sizes ranging from 1.5 mm to 4.5 mm, and in tip angles
ranging from zero to 90 degrees. We currently sell 21 models for arthroscopy in
various tip sizes, angles and shapes, enabling the surgeon to ablate different
volumes of tissue and to reach treatment sites not readily accessible by
existing mechanical instruments and motorized cutting tools. In addition, we
also produce disposable devices which provide other functionalities, including
suction and fluid management.

   We commercially introduced the Arthroscopic System in December 1995. The
list price of the controller, including the cable, is approximately $7,500. The
disposable devices have list prices ranging from approximately $115 to $195,
and typically one disposable device is used per procedure.

The Spinal Market

   Chronic back pain afflicts approximately nine million people in the U.S.
Approximately one-half of those afflicted suffer from disabling pain; chronic
back pain is the most common reason for disability for persons under age 50 and
is the second leading cause of workers' absenteeism. The major causes of
persistent, often disabling, back pain are disruption of a portion of the disc,
chronic inflammation of the disc, also known as herniation, or relative
instability of the vertebral bodies surrounding a given disc, such as the
instability that often occurs due to a degenerative disease. Intervertebral
discs mainly function to cushion and tether the vertebrae, providing
flexibility and stability to the patient's spine. As discs degenerate, they
lose their water

                                       34
<PAGE>

content and height, bringing the adjoining vertebrae closer together. This
results in a weakening of the shock absorption properties of the disc and a
narrowing of the nerve openings in the sides of the spine which may pinch these
nerves. This disc degeneration can eventually cause back and leg pain.

   Often, inflammation from disc herniation can be treated successfully by non-
surgical means, such as rest, therapeutic exercise, or through the use of anti-
inflammatory medications. In some cases, the disc tissue is irreparably
damaged, thereby necessitating a discectomy, the removal of a portion of the
disc or the entire disc to eliminate the source of inflammation and pressure.
In more severe cases, the adjacent vertebral bodies must be stabilized
following excision of the disc material to avoid recurrence of the disabling
back pain. One approach to stabilizing the vertebrae, termed spinal fusion, is
to insert an interbody graft or implant into the space vacated by the
degenerative disc. In this procedure, a small amount of bone may be grafted
from other portions of the body, such as the hip, and packed into the implants.
This allows the bone to grow through and around the implant, fusing the
vertebral bodies and alleviating the pain.

   Another surgical treatment for degenerative disc disease, termed
laminectomy, involves cutting away the lamina, the bony plate that connects the
bony ridges of the spine, known as pedicles. This allows the nerve tissue to
shift position to release pressure.

   Until recently, spinal discectomy, laminectomy and fusion procedures
resulted in major operations and traumatic dissection of muscle and bone
removal or bone fusion. The open surgical procedures are invasive and typically
require a team of surgeons due to the length and complexity of the procedure.
Recovery time is also lengthy. To overcome the disadvantages of traditional
traumatic spinal surgery, minimally-invasive spinal surgery was developed. In
minimally-invasive spinal procedures, the spinal canal is not penetrated and
therefore bleeding with ensuing scarring is minimized or completely avoided. In
addition, the risk of instability from ligament and bone removal is generally
lower in minimally-invasive procedures than with open discectomy. Further, less
trauma during surgery often results in rapid rehabilitation and fast recovery.

   We believe that approximately 1.9 million spine procedures are performed
annually worldwide. We also believe that spinal surgery is the most rapidly
growing segment of orthopedic surgery.

Conventional Treatment Methodologies for Treatment of Spine Diseases and
Disorders

   Techniques for the treatment of spinal diseases or disorders include laser
and mechanical techniques. These procedures can be "open" or minimally invasive
depending on the complexity, and generally require the surgeon to form a
passage or operating corridor from the external surface of the patient to the
spinal disc(s) for passage of surgical instruments and implants. Typically, the
formation of this operating corridor requires the removal of soft tissue,
muscle or other types of tissue. This tissue is usually removed with mechanical
or powered instruments, such as, graspers, cutters and drills. Multiple
mechanical and powered instruments must be used and are time-intensive. In
addition, these instruments sever blood vessels within this tissue, usually
causing profuse bleeding that obstructs the surgeon's view of the target site.

   Once the operating corridor is established, the nerve root is retracted and
a portion or all of the disc is removed with mechanical or powered instruments.
These instruments are typically slow and tedious, and can require up to 40
minutes to remove a single disc. In addition, these instruments, particularly
powered instruments, are not extremely precise, and it is often difficult
during the procedure to differentiate between the target disc tissue and other
structures within the spine, such as bone, cartilage, ligaments, nerves and
surrounding tissue. Thus, the surgeon must be extremely careful to minimize
damage to the cartilage and bone within the spine, and to avoid damaging
nerves.

   Both lasers and monopolar radio frequency devices have been used in spinal
surgery. We believe both have significant drawbacks. Lasers are expensive and
tedious to use. Another disadvantage with lasers is the difficulty in judging
the depth of tissue ablation. Because healthy tissue, bones, ligaments and
nerves often lie within close proximity of the spinal disc, it is essential to
maintain a minimum depth of tissue penetration.

                                       35
<PAGE>

Monopolar radio frequency devices increase the risk of unwanted electrical
stimulation to portions of the patient's body by utilizing electric current
that disperses into the patient's body.

The ArthroCare Spinal Surgery System

   In September 1999, we announced our expansion into the spinal surgery
market. Our Spinal Surgery System is CE marked, and we have applied for 510(k)
clearance for use of the system in spinal surgery procedures in the United
States. We anticipate receiving this 510(k) clearance by the end of 1999, but
we cannot assure you that this will occur. Our spinal surgery products, based
on our Coblation technology, include multi-functional disposable devices
optimized for spinal surgery. The disposable products are compatible with the
controller that is used for arthroscopic and ENT surgery procedures.

   Our controller is used to deliver radio frequency energy to the disposable
devices. The disposable devices are intended for single use and utilize
multiple or single electrodes to ablate tissue while simultaneously sealing
bleeding vessels. In some cases, our disposable devices may also include one or
more tubes for the delivery of electrically conductive fluid to the target site
and/or for suction capability. The incorporation of ablation, suction and fluid
management into a single disposable device potentially reduces operative time
and expense. Although we have had limited clinical experience with these
products in spinal surgery procedures, we believe physician and patient
benefits experienced in arthroscopic surgery, such as more rapid recovery time,
reduced thermal injury to tissue and reduced post-operative pain when compared
to existing techniques, could apply to spinal surgery procedures.

   Our disposable devices consist of the ACCESS SpineWand and the DisCoblator.
The ACCESS SpineWand is a bipolar electrosurgical device designed for
controlled ablation of soft tissue. We believe that the ACCESS SpineWand will
be an effective tool for creating precise incisions through connective tissue
to provide access to the disc in discectomy, laminectomy and fusion procedures.
In addition, we believe that the ACCESS SpineWand may be effectively used to
remove soft tissue from bones in preparation for fusion procedures.

   The DisCoblator is a bipolar electrosurgical device designed for aggressive
ablation and removal of large tissue volumes. The DisCoblator includes fluid
delivery and suction capabilities and incorporates an active screen electrode
design to inhibit clogging. We plan to initially market the DisCoblator to
volumetrically remove a portion or all of the disc during discectomy and fusion
procedures. Although there has been limited clinical experience with this
product, we believe that the DisCoblator is capable of removing a disc in
substantially less time than mechanical instruments, such as graspers or
cutters.

The Ear, Nose and Throat (ENT) Market

   We believe that in 1998, approximately 1.4 million ENT procedures were
performed worldwide. Surgical procedures are commonly used to treat ear, nose
and throat disorders, including obstructive sleep apnea, snoring and other
obstructions of the sinus and nasal passages. For example, surgical approaches
for the treatment of obstructive sleep apnea include the removal of excess
tissue from the upper airway or moving the lower jaw forward to widen the
patient's airway. These procedures are performed by highly specialized
surgeons, are expensive, are extremely painful for the patient and involve
lengthy recovery periods. Non-invasive treatment approaches include continuous
positive airway pressure, or CPAP, which requires the patient to wear a nasal
mask connected to an airflow generator that forces air through the nasal
passages during sleep.

   Conventional treatment methodologies for ENT surgical procedures have been
performed by lasers, endoscopes and microsurgical tools. We believe our
Coblation technology can be used in numerous types of ENT procedures.

The ArthroCare ENT Surgery System

   Our ENT surgery system uses the same technology as the Arthroscopic System,
which ablates tissue through a more precise and significantly cooler process
than that of traditional electrosurgery devices. Our ENT

                                       36
<PAGE>

surgery system is a radio frequency, electrosurgical device intended to bring
improved control and functionality to ENT surgeons. The ENT surgery system
incorporates a disposable bipolar device, a connecting cable and radio
frequency controller. The controller is used to deliver radio frequency energy
to the disposable device. The disposable device is intended for single use and
utilizes multiple or single electrodes to ablate tissue while simultaneously
sealing bleeding vessels. We believe that our products will produce improved
surgical results, reduce pain and speed recovery for the patient.

   Our ENT surgery system is CE marked, and we have received 510(k) clearances
for use of the system in general head, neck and oral surgical procedures and
minimally-invasive sinus surgery in the United States. We have been marketing
the ENT surgery products through a network of distributors and regional sales
managers in the United States and internationally since February 1999.

The Cosmetic Surgery Market

   The cosmetic surgery market is primarily comprised of procedures to
rejuvenate, remove or reduce wrinkles of the skin, remove scarring or lesions
and perform traditional techniques such as face lifts or brow lifts. Of the
approximately 1.6 million cosmetic surgery procedures performed annually
worldwide, approximately 325,000 were laser resurfacing procedures performed in
the United States to reduce the wrinkled appearance of skin.

Conventional Treatment Methodologies for Cosmetic Surgery

   Conventional methods of skin resurfacing include chemical peels,
dermabrasions and laser resurfacing. In chemical peels, an acid-based chemical
solution is used to improve the texture of the skin by removing its damaged
outer layers. In dermabrasion, surgical scraping is used to remove the skin's
top layers. Chemical peels and dermabrasions have minimal effect on wrinkles,
and can cause scarring and pigmentary changes. Lasers are often used to achieve
wrinkle reduction and removal. The conventional continuous wave carbon dioxide,
or CO\\2\\, laser has been used successfully to resurface skin. However, the
excessive heat diffusion into surrounding skin during the use of this laser
results in unwanted cell death and unacceptable rates of scarring and impaired
wound healing. The new generation of pulsed lasers has proven to be an
effective method for the treatment of surface imperfections and irregularities,
including wrinkles, pigmented spots, and acne scars. These lasers permit
precise ablation of tissue with minimal accumulation and dispersion of heat
resulting in minimal thermal damage and char.

The ArthroCare Cosmetic Surgery System

   Our Cosmetic Surgery System utilizes the same technology as the Arthroscopic
System, which removes tissue through a more precise and significantly cooler
process than traditional electrosurgery systems or dermatologic lasers. Our
Cosmetic Surgery System is a radio frequency, electrosurgical device for use in
skin resurfacing and other dermatologic and cosmetic procedures. Our Cosmetic
Surgery System incorporates a disposable bipolar device, a connecting
resterilizable handpiece with cable and a radio frequency controller. This
controller design differs from the controllers used in arthroscopy, ENT surgery
and spinal surgery. The controller delivers radio frequency energy to the
multi-electrode or single electrode disposable device. Clinical trials indicate
that our Cosmetic Surgery System may enable the physician to reduce wrinkles
and improve cosmetic appearance.

   Our Cosmetic Surgery System is CE marked for skin resurfacing procedures,
and we have received 510(k) clearance for use of the system in general
dermatologic procedures in the United States. We are pursuing additional
clearances, which are anticipated by the end of 1999, that will allow the
system to be marketed in the United States specifically for skin resurfacing
and wrinkle reduction. We have been conducting clinical studies for use of the
Cosmetic Surgery System for skin resurfacing and wrinkle reduction since June
1998 and included the resulting data in our application for 510(k) clearance.

   In January 1999, we entered into an exclusive distribution agreement with
Collagen Aesthetics, Inc. to license, market and distribute our Coblation-based
products for cosmetic surgical procedures, typically

                                       37
<PAGE>

performed by cosmetic surgeons, dematologists and facial plastic surgeons,
including some ENT physicians. Under the terms of the agreement, Collagen
Aesthetics, Inc. is the exclusive worldwide distributor of our Cosmetic Surgery
System. Collagen Aesthetics, Inc. was recently acquired by Inamed Corporation.

ArthroCare's Cardiology Program

   We have established a program to explore the application of our Coblation
technology in various areas within cardiology. One of our programs is in
myocardial revascularization, a newly-introduced procedure for treatment of
heart disease. Lasers have been recently introduced for use in myocardial
revascularization. However, we believe that the high capital cost associated
with lasers may impede the widespread adoption of this technology.

   We believe that Coblation technology could be used to perform myocardial
revascularization. We have an agreement with Boston Scientific Corporation
under which they will further develop, seek regulatory approvals for and market
our Coblation technology for use in this application.

Benefits of Our Coblation Technology

   Our patented Coblation technology, delivered in the form of multi-electrode
and single electrode, bipolar disposable devices, offers a number of benefits
that we believe may provide advantages over competing surgical methods and
devices. The principal benefits include:

  . EASE OF USE.  Our Coblation-based soft-tissue surgery systems perform
    many of the functions of mechanical tools, power tools and electrosurgery
    instruments, allowing the surgeon to use a single instrument. The
    lightweight device is simple to use and complements the surgeon's
    existing tactile skills without the need for extensive training.

  . PRECISION. In contrast to conventional tools, our Coblation-based soft-
    tissue surgery systems permit surgeons to perform more precise tissue
    ablation and sculpting. We believe this may result in more rapid patient
    rehabilitation.

  . BENEFITS TO PATIENTS. Coblation technology operates at cooler
    temperatures than traditional electrosurgical tools. This can lead to
    significant benefits for patients treated with Coblation-based disposable
    devices due to the minimal amount of thermal injury to surrounding
    tissue. As a result, we believe that patients are likely to experience
    less trauma and pain following surgery and may recover more quickly.

  . SIMULTANEOUS ABLATION AND SEALING OF BLEEDING VESSELS. Our Coblation-
    based soft-tissue surgery systems allow for the efficient sealing of
    bleeding vessels without changing tools.

  . COST REDUCTION. Our Coblation soft-tissue surgery systems eliminate the
    need to introduce multiple instruments to remove and sculpt tissue and
    seal bleeding vessels. We believe this may reduce operating time and
    thereby produce cost savings for health care providers.

Collaborative Arrangements

   Collagen Aesthetics, Inc. In early 1999, we entered into a license and
distribution agreement with Collagen Aesthetics, Inc. Under this agreement,
Collagen Aesthetics, Inc. acquired exclusive, worldwide marketing rights for
our cosmetic surgery products. Collagen Aesthetics, Inc. was recently acquired
by Inamed Corporation. We will continue to perform product development,
manufacturing, and clinical and regulatory functions for our Cosmetic Surgery
System.

   Boston Scientific Corporation. In February 1998, we entered into a license
and distribution agreement under which Boston Scientific Corporation will help
to develop, obtain regulatory approval for and market products based on our
Coblation technology for myocardial revascularization procedures. Under the
agreement, Boston Scientific Corporation acquired exclusive licensing rights to
our intellectual property in this field.

                                       38
<PAGE>

Boston Scientific Corporation will pay licensing fees to us upon achievement of
designated clinical and regulatory milestones, and royalties on sales of
resulting products. Boston Scientific Corporation will perform clinical and
regulatory functions, product development and sales and marketing. We will also
focus on product development and will manufacture devices for Boston Scientific
Corporation.

Research And Development

   We have focused our research and development efforts in two areas. First, in
response to physician feedback, we are continually working on enhancements to
designs of our products to provide greater versatility in existing features and
functions. In addition, we continue to design new disposable devices that
incorporate added functionalities. Second, we are exploring new applications of
our Coblation technology in other soft-tissue surgical markets. We have
undertaken preliminary studies and development for the use of our technology in
several fields.

Marketing And Sales

   The company estimates that of the 18,500 orthopedic surgeons in the United
States, approximately 80% perform arthroscopy and approximately 40% consider
arthroscopy to be their major practice area. We shipped more than 5,000
controller units and approximately 450,000 disposable devices as of July 3,
1999. We use a combination of distributors supported by regional sales
managers, a small direct sales force and corporate partners to sell our
products both domestically and internationally.

   We are marketing and selling our arthroscopic and ENT surgery products in
the United States through a network of independent distributors supported by
regional sales managers and a small direct sales force. We have more than 35
distributors representing more than 225 field sales representatives in the
United States. Collagen Aesthetics, Inc. is the exclusive, worldwide
distributor for our Cosmetic Surgery System.

   We are marketing and selling our Spinal Surgery System internationally and
are building our domestic distribution capabilities in this area in
anticipation of 510(k) clearance. We will utilize some of our existing
distributors, add new specialized spinal surgery product distributors, and
increase the number of our regional managers to facilitate the introduction of
this new product line.

   We have established distribution capability in certain countries by means of
exclusive and non-exclusive distribution agreements with corporations,
including with Arthrex for the distribution of our arthroscopy products in
Europe, South Africa, South and Central America and Russia; Kobayashi
Pharmaceutical for the distribution of our arthroscopy products in Japan; and
Smith & Nephew, Inc. for the distribution of our arthroscopy and ENT surgery
products in New Zealand and Australia. We have also established distribution
capability through relationships with distributors in Korea, Taiwan, Canada,
Mexico, the Caribbean, the Middle East and Northern Africa.

   We believe the use of our products is generally intuitive to surgeons and
does not require extensive training. We frequently conduct training seminars
and demonstrations at regional training centers and trade shows. Our partners
also conduct training activities in their areas of responsibility.

   At hospitals and surgical centers where several procedures can be performed
simultaneously, the procurement of multiple controllers is required. We have
offered our controllers at substantial discounts in the past and may be
required to continue to offer such discounts to generate demand for our
disposable devices. In addition, motorized and mechanical instruments, lasers
and electrosurgery systems currently used by hospitals, surgical centers and
private physicians have become widely accepted. If physicians do not determine
that our soft-tissue surgery systems are an attractive alternative to
conventional means, our business would be materially adversely affected.

                                       39

Manufacturing and Single Source Suppliers

   Our disposable devices and controllers are currently manufactured in our
10,000 square foot manufacturing facility in Sunnyvale, California. Our
products are manufactured from several components, some of which are supplied
to us by third parties.

   Most of the components we use in the manufacture of our products are
available from more than one supplier. For some components, however, there are
relatively few alternate sources of supply and the establishment of additional
or replacement suppliers for such components may not be accomplished quickly.
With respect to a few components, we rely upon single source suppliers. For
example, one single source supplier provides us with a component used in
substantially all of our disposable devices. In addition, we use a single
subcontractor to sterilize our disposable devices. If the services of this
subcontractor were interrupted, we cannot be sure that we would be able to
identify and qualify an alternate sterilizer prior to the occurrence of any
disruption in our manufacturing process. We do not believe any such disruption
is likely since this subcontractor has several facilities from which it is able
to provide sterilization services to us. We are dependent upon these third
parties for the manufacture of our products, and our profit margins and our
ability to develop and deliver such products on a timely basis may be adversely
affected by the lack of alternative sources of supply. See "Risk Factors--We
Have Limited Manufacturing Experience" for a description of the potential
disruption in supply of our products and risks to our operations resulting from
our reliance upon single source suppliers.

   Manufacture of the controllers was brought in-house in late 1997 for
purposes of maintaining process control, ensuring adequate supply, and
leveraging fixed costs. We manufacture three different controller models for
which the manufacturing process is substantially the same.

   We currently manufacture 32 different versions of our disposable devices.
Due to the various attributes of our disposable devices, which include, among
other functions, fluid management and suction, the manufacturing process is
varied. In order to improve yields, we have recently converted from batch
processing of our disposable devices to a continuous manufacturing process.

   We have established quality assurance systems in conformance with the FDA's
Quality System Regulation, or QSR. Our facility has received ISO 9001/EN46001
certification and is in conformance with the Medical Device Directive, or MDD,
for sale of products in Europe.

Patents And Proprietary Rights

   Our ability to compete effectively depends in part on developing and
maintaining the proprietary aspects of our Coblation technology. We own 19
issued U.S. patents and 10 issued international patents. In addition, we have
more than 60 pending U.S. patent applications and over 40 international patent
applications corresponding to 20 of the U.S. filings. The initial U.S. patent
is currently set to expire in 2008, three issued patents are currently expected
to expire between 2008 and 2012 and the other 15 U.S. patents are expected to
expire between 2014 and 2016. We believe that the issued patents are directed
at, among other things, both the core technology used in our soft-tissue
surgery systems, including both multi-electrode and single electrode
configurations of our disposable devices, as well as the use of Coblation
technology in specific surgical procedures.

   The issued patents are directed at, among other things, the following:

   . systems and methods for applying radio frequency energy to tissue in
     the presence of electrically conductive fluid such as isotonic saline;

   . disposable devices having an electrode array and a system designed to
     supply current independently to individual electrodes; and

   . systems and methods for employing radio frequency energy in urology,
     gynecology, ENT, cosmetic surgery and cardiac procedures.

                                       40
<PAGE>

   The pending patent applications include coverage for the fundamental tissue
ablation and cutting technology as well as methods and apparatus for specific
procedures.

   We cannot assure you that the patents we have obtained, or any patents that
we may obtain as a result of our U.S. or international patent applications,
will provide any competitive advantages for our products or that they will not
be successfully challenged, invalidated or circumvented in the future. In
addition, we cannot assure you that competitors, many of whom 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 our ability to make, use and sell our products either in the United States
or in international markets.

   A number of other companies and universities and research institutions have
filed patent applications or have issued patents relating to monopolar and/or
bipolar electrosurgical methods and apparatus. In addition, we have become
aware of, and may become aware of in the future, patent applications and issued
patents that relate to our products and/or the surgical applications and issued
patents and, in some cases, have obtained internal and/or external opinions of
counsel regarding the relevance of certain issued patents to our products. We
do not believe that our products currently infringe any valid and enforceable
claims of the issued patents that we have reviewed. However, if third-party
patents or patent applications contain claims infringed by our technology and
such claims are ultimately determined to be valid, we cannot assure you that we
would be able to obtain licenses to those patents at a reasonable cost, if at
all, or be able to develop or obtain alternative technology. The inability to
do either would have a material adverse effect on our business, financial
condition, results of operations and future growth prospects. We cannot assure
you that we will not have to defend ourself in court against allegations of
infringement of third-party patents.

   In addition to patents, we rely on trade secrets and proprietary know-how,
which we seek to protect, in part, through confidentiality and proprietary
information agreements. We require our key employees and consultants to execute
confidentiality agreements upon the commencement of an employment or consulting
relationship with us. These agreements generally provide that all confidential
information developed or made known to the individual by us during the course
of the individual's relationship with us, is to be kept confidential and not
disclosed to third parties. These agreements also generally provide that
inventions conceived by the individual in the course of rendering services to
us shall be our exclusive property. We cannot assure you that employees will
not breach the agreements, that we would have adequate remedies for any breach
or that our trade secrets will not otherwise become known to or be
independently developed by competitors.

   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. We cannot assure you that we will not become subject
to patent infringement claims or litigation or interference proceedings
declared by the United States Patent and Trademark Office, or USPTO, to
determine the priority of inventions. On February 13, 1998 we filed a lawsuit
against Ethicon, Inc., Mitek Surgical Products, a division of Ethicon, Inc.,
and GyneCare, Inc. alleging among other things, infringement of several of our
patents. The lawsuit has been settled. The defense and prosecution of this
lawsuit and intellectual property suits generally, USPTO interference
proceedings and related legal and administrative proceedings are both costly
and time-consuming. We believe that the lawsuit was necessary, and if others
violate our proprietary rights, further litigation may be necessary to enforce
our patents, to protect trade secrets or know-how owned by us or to determine
the enforceability, scope and validity of the proprietary rights of others. Any
litigation or interference proceedings will be costly and cause significant
diversion of effort by our technical and management personnel. An adverse
determination, other litigation or interference proceedings to which we may
become a party could subject us to significant liabilities to third parties,
require disputed rights to be licensed from third parties or require us to
cease using such technology. Although patent and intellectual property disputes
in the medical device area have often been settled through licensing or similar
arrangements, costs associated with such arrangements may be substantial and
could include ongoing royalties. Furthermore, we cannot be sure that we could
obtain necessary licenses on satisfactory terms, if at all. Adverse
determinations in a judicial or administrative proceeding or failure to obtain
necessary licenses could prevent us

                                       41
<PAGE>

from manufacturing and selling our products, which would have a material
adverse effect on our business, financial condition, results of operations, and
future growth prospects.

Competition

   We believe that the principal competitive factors in the soft-tissue surgery
markets include:

  . acceptance by leading physicians;

  . improved patient outcomes;

  . superior product quality;

  . the publication of peer-reviewed clinical studies;

  . product innovation;

  . sales and marketing capability; and

  . strong intellectual property.

 Arthroscopy

   We compete directly with the providers of tissue removal systems including
conventional electrosurgical systems, manual instruments, power shavers and
laser systems, in arthroscopic procedures. Smith & Nephew Endoscopy, which owns
Acufex Microsurgical, Inc. and Dyonics, Inc.; Conmed Corporation, including its
Linvatec unit; Medtronic, Inc., which owns Sofamor Danek; and Stryker Corp.
each have large shares of the market for manual instruments, power shavers and
arthroscopes.

   Johnson & Johnson, including Mitek, a division of its Ethicon, Inc. unit, is
marketing a bipolar electrosurgical system developed by Gyrus Medical Ltd., a
company based in the United Kingdom. The bipolar electrosurgical system
marketed by Mitek competes directly with our tissue ablation and shrinkage
technology in arthroscopy. In addition, the Linvatec unit of Conmed Corporation
is marketing a monopolar electrosurgical tool for tissue ablation in
arthroscopy. Oratec Interventions Inc. manufactures and sells a monopolar
tissue shrinkage system that competes directly with our arthroscopic products.
The tissue shrinkage market represents a small portion of the overall market in
arthroscopy for our products.

   We believe that the Arthroscopic System, comprising the controller unit and
disposable devices, presents a competitive pricing structure compared to
alternative tools being used in arthroscopic procedures. While our disposable
devices perform many functions in one tool, most competitive disposable devices
only perform a single function. In such cases, multiple disposable or reusable
devices would be required. Laser systems have a significantly higher capital
cost than our controller and require significant ongoing maintenance and
operating expenses. We are also aware of additional competitors that may
commercialize products using technology similar to ours.

 Spinal Surgery

   We believe that Coblation technology will compete effectively against
conventional tissue removal technology used in spinal procedures, such as
mechanical instruments and powered instruments. We will compete with large
companies in the spinal surgery market, and are aware of several small
companies offering alternative treatments for back pain that may indirectly
compete with our products.

 Ear, Nose and Throat Surgery

   There are large companies, such as Smith & Nephew, Inc., Stryker Corp.,
Xomed Surgical Products, Inc., which was recently acquired by Medtronic, Inc.,
and Conmed Corporation, which have shares of the market for manual and powered
instruments for minimally-invasive sinus surgery. In addition, we face
competition from

                                       42
<PAGE>

laser companies, such as ESC Medical Systems Ltd., which develops and markets
lasers for various ENT surgery applications. We expect that competition from
these and other well-established competitors will increase as will competition
from smaller medical device companies, such as Somnus Medical Technologies,
Inc., Elmed Inc. and Ellman International, Inc. Somnus Medical Technologies,
Inc. manufactures and sells medical devices that utilize radio frequency energy
for the treatment of upper airway disorders, such as snoring and obstructive
sleep apnea. Elmed Inc. and Ellman International, Inc. both manufacture and
sell a variety of medical devices that use conventional radio frequency energy
for tissue removal, cutting and/or coagulation for the treatment of snoring and
other ENT surgery procedures.

 Cosmetic Surgery

   The cosmetic surgery industry includes a number of large and well
established companies that provide devices for rejuvenating skin, hair removal,
scar removal, the treatment of vascular and pigmented lesions and other
applications, including companies that manufacture and sell dermabrasion
equipment or chemical peels, and companies that manufacture and sell lasers. In
skin resurfacing, we will directly compete with much larger companies that
manufacture lasers for medical use, such as Coherent Medical Group and ESC
Medical Systems Ltd. ESC recently merged with Laser Industries, Ltd. The
combined company develops and markets lasers for a broad range of cosmetic
applications including the non-invasive treatment of varicose veins and other
benign vascular lesions, hair removal, skin rejuvenation and others. In
addition, other large companies manufacture and sell medical devices that use
radio frequency energy for certain applications in dermatology and cosmetic
surgery.

   We cannot assure you that we can effectively convince surgeons and
physicians to adopt our Coblation technology in the face of competition. In
addition, we cannot be sure that these or other companies will not succeed in
developing technologies and products that are more effective than ours or that
would render our technology or products obsolete or uncompetitive. Many of
these competitors have significantly greater financial, manufacturing,
marketing, distribution and technical resources than us. We have received
510(k) clearances to market tissue ablation products to treat disorders in
other surgical fields that we may enter. These fields are intensely competitive
and we cannot assure you that these potential products would be successfully
marketed.

Third-Party Reimbursement

   In the United States, health care providers, such as hospitals and
physicians, that purchase medical devices, such as our products, generally rely
on third-party payors, principally federal Medicare, state 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 arthroscopic, ENT
surgery and spinal surgery procedures performed using devices that have
received FDA approval has generally been available in the United States.
Generally, cosmetic procedures are not reimbursed. In addition, some health
care providers are moving toward a managed care system in which providers
contract to provide comprehensive health care for a fixed cost per person.
Managed care providers are attempting to control the cost of health care by
authorizing fewer elective surgical procedures.

Legal Proceedings

   On February 13, 1998, we filed a lawsuit against Ethicon, Inc., Mitek
Surgical Products, a division of Ethicon, Inc. and GyneCare, Inc. in the United
States District Court for the Northern District of California. We settled this
patent litigation on June 24, 1999. Under the terms of the settlement, Ethicon,
Inc. has licensed our U.S. patents in the arthroscopy and gynecology markets
and we have dismissed the legal action. Ethicon, Inc. has paid us a license fee
and will pay us ongoing royalties on sales in the United States of certain
arthroscopy and gynecology products. The settlement agreement also established
a procedure for resolution of certain potential intellectual property disputes
in these two markets without litigation.

                                       43

   On February 4, 1999, Xomed Surgical Products, Inc. filed a complaint against
us in the Fourth Judicial Circuit, Duval County, Florida, alleging breach of
contract by us. In the complaint, Xomed has demanded a full refund of the
amounts paid for certain products Xomed bought from us, and for a portion of an
exclusive license fee Xomed paid pursuant to an exclusive license and
distribution agreement between Xomed and us. We terminated this license and
distribution agreement on February 5, 1999. We believe the suit is without
merit, and filed a Motion to Dismiss and Answer to the Complaint on May 3,
1999. In addition, we filed two counterclaims against Xomed for damages caused
by Xomed's failure to perform under the contract and for a certain milestone
payment owed to us by Xomed.

   On February 4, 1999, California Medical, Inc. filed a complaint in
California state court against us alleging breach of contract, interference
with contractual and economic relations, trade libel, misappropriation of trade
secrets, misrepresentation and unfair competition. California Medical is a
former distributor of our products in Northern California. We terminated our
distribution agreement with California Medical at the end of 1997. We believe
the suit is without merit and filed a motion to dismiss on May 31, 1999. As a
result of the hearing on our motion to dismiss, California Medical filed an
amended complaint on August 9, 1999, in which they dropped the causes of action
alleging misrepresentation. The parties' attempt to resolve the dispute through
mediation on September 17, 1999 was unsuccessful.

   On March 24, 1999, one of our former employees filed a complaint of action
for sexual harassment in violation of the Fair Employment and Housing Act and
retaliation in violation of the Fair Employment and Housing Act. We filed a
response to the complaint on June 23, 1999. At the case management conference
on July 27, 1999 the parties stipulated mediation. According to the complaint,
the demand exceeds $25,000.

Government Regulation

 United States

   Our products are regulated in the United States as medical devices by the
FDA under the Federal Food, Drug, and Cosmetic Act, or the FDC Act, and require
premarket clearance or approval by the FDA prior to commercialization. Pursuant
to the FDC Act, the FDA regulates the research, testing, manufacture, safety,
labeling, storage, record keeping, advertising, distribution and production of
medical devices in the United States. Noncompliance with applicable
requirements can result in warning letters, 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, and criminal prosecution. Failure to comply with the
regulatory requirements could have a material adverse effect on our business,
financial condition, results of operations and future growth prospects.

   Unless an exemption applies, before a new device can be introduced into the
market in the United States, the manufacturer or distributor must obtain FDA
clearance of a 510(k) notification or approval of a PMA application. If a
medical device manufacturer or distributor can establish that a device is
"substantially equivalent" to a "predicate device," i.e. a legally marketed
Class I or Class II device or a preamendment Class III device (i.e. one that
was in commercial distribution before May 28, 1976) for which the FDA has not
called for PMAs, the manufacturer or distributor may seek clearance from the
FDA to market the device by submitting a 510(k) notification. The 510(k)
notification will need to be supported by appropriate data establishing the
claim of substantial equivalence to the satisfaction of the FDA.

   Following submission of the 510(k) notification, the manufacturer or
distributor may not place the device into commercial distribution until an
order is issued by the FDA. Currently, the FDA typically responds to the
submission of a 510(k) notification within 90 to 120 days, but it may take
significantly longer. An FDA order may declare that the device is substantially
equivalent to another legally marketed device and allow the proposed device to
be marketed in the United States. The FDA, however, may determine that the
proposed device is not substantially equivalent or require further information,
including clinical data, to make a determination regarding substantial
equivalence. Such determination or request for additional information could

                                       44
<PAGE>

delay market introduction of the products that are the subject of the 510(k)
notification. After a device receives 510(k) clearance, any modification that
could significantly affect its safety or effectiveness, or that would
constitute a major change in the intended use of the device, requires a new
510(k) clearance.

   We have received 510(k) clearance to market our Arthroscopic System for
surgery of the knee, shoulder, elbow, wrist, hip and ankle joints. In addition,
we have received 510(k) clearance to market our Cosmetic Surgery System in
general dermatology procedures and are pursuing additional clearances that will
allow our Cosmetic Surgery System to be marketed in the United States
specifically for skin resurfacing and wrinkle reduction. With respect to our
ENT surgery system, we have received 510(k) clearances to market our ENT
surgery system in general head, neck, oral and sinus surgical procedures. We
have applied for, but not yet received, 510(k) clearance to market our Spinal
Surgery System. We cannot assure you that we will be able to obtain necessary
clearances or approvals to market our products on a timely basis, if at all.
Delays in receipt or failure to receive such clearances or approvals, the loss
of previously received clearances or approvals, or failure to comply with
existing or future regulatory requirements could have a material adverse effect
on our business, financial condition, results of operations and future growth
prospects.

   After a device receives 510(k) clearance, any modification that could
significantly affect its safety or effectiveness, or that would constitute a
major change in the intended use of the device, requires a new 510(k)
clearance. The FDA requires each manufacturer to make this determination in the
first instance, but the FDA can review any such decision. If the FDA disagrees
with a manufacturer's decision not to seek a new 510(k) clearance, the agency
may retroactively require the manufacturer to submit a premarket notification
requiring 510(k) clearance. The FDA also can require the manufacturer to cease
marketing and/or recall the modified device until 510(k) clearance is obtained.
We have modified some of our marketed devices, but have determined that, in our
view, new 510(k) clearances are not required. No assurance can be given that
the FDA would agree with any of our decisions not to seek 510(k) clearance. If
the FDA requires us to seek 510(k) clearance for any modification, the FDA also
may require us to cease marketing and/or recall the modified device until we
obtain a new 510(k) clearance.

   If a manufacturer or distributor of medical devices cannot establish that a
proposed device is substantially equivalent to a legally marketed predicate
device, the device is placed in Class III and the manufacturer or distributor
must seek premarket approval of the proposed device through submission of a PMA
application. A PMA application must be supported by extensive data, including,
in many instances, preclinical and clinical trial data, as well as extensive
literature, to prove the safety and effectiveness of the device to the FDA's
satisfaction. Following receipt of a PMA application, if the FDA determines
that the application is sufficiently complete to permit a substantive review,
the FDA will "file" the application. Under the FDC Act, the FDA has 180 days to
review a PMA application, although the review of such an application more often
occurs over a protracted time period, and generally takes approximately two
years or more from the date of filing to complete.

   The PMA application approval process can be expensive, uncertain and
lengthy. A number of devices for which premarket approval has been sought by
other companies have never been approved for marketing. The review time is
often significantly extended by the FDA, which may require more information or
clarification of information already provided in the submission. In addition,
the FDA will inspect the manufacturing facility to ensure compliance with QSR
requirements prior to approval of an application. If granted, the approval of
the PMA application may include significant limitations on the indicated uses
for which a product may be marketed.

   If necessary, we will file a PMA application with the FDA for approval to
sell our potential products commercially in the United States when we have
developed such products. We cannot assure you that we will be able to obtain
necessary PMA application approvals to market these products on a timely basis,
if at all, and delays in receipt or failure to receive these approvals, the
loss of previously received approvals, or failure to comply with existing or
future regulatory requirements could have a material adverse effect on our
business, financial condition, results of operations and future growth
prospects.

                                       45
<PAGE>


   If human clinical trials of a device are required and if the device presents
a "significant risk," the manufacturer or the distributor of the device is
required to file an Investigational Device Exemption, or IDE, application prior
to commencing human clinical trials. The IDE application must be supported by
data, typically including the results of animal and, possibly, mechanical
testing. Sponsors of clinical trials are permitted to sell investigational
devices distributed in the course of the study, provided such costs do not
exceed recovery of the costs of manufacture, research, development and
handling. The clinical trials must be conducted under the auspices of an
independent Institutional Review Board, or IRB, established pursuant to FDA
regulations, and with appropriate informed consent of the patient.

   We are also required to register as a medical device manufacturer with the
FDA and state agencies, such as the California Department of Health Services,
or CDHS, and to list our products with the FDA. As such, we are subject to
inspections by both the FDA and the CDHS for compliance with the FDA's QSR
requirements and other applicable regulations. These regulations require that
we maintain our documents in a prescribed manner and follow quality assurance
procedures with respect to manufacturing, testing and control activities.
Further, we and third party manufacturers of our products are required to
comply with various FDA requirements for design, safety, advertising and
labeling. We cannot assure you that we and our component suppliers can avoid
problems involving regulatory compliance, product recalls or quality control
and assurance.

   Regulations regarding the manufacture and sale of our products are subject
to change. We cannot predict the effect, if any, that such changes might have
on our business, financial condition, results of operations and future growth
prospects.

   We must comply with numerous federal, state and local laws relating to such
matters as safe working conditions, manufacturing practices, environmental
protection, fire hazard control and hazardous substance disposal. No assurance
can be given that we will not be required to incur significant costs to comply
with such laws and regulations in the future or that such laws or regulations
will not have a material adverse effect on our business, financial condition,
results of operations and future growth prospects.

 International

   International sales of our products are subject to strict regulatory
requirements. The regulatory review process varies from country to country. We
have obtained regulatory clearance to market the Arthroscopic System in
Australia, Europe, Japan, Canada and Mexico, to market our Cosmetic Surgery
System in Europe and Canada, to market our ENT surgery system in Europe and to
market our Spinal Surgery Systems in Europe, but have not obtained any other
international regulatory approvals permitting sales of our products outside of
the United States. We are seeking and we intend to seek regulatory approvals in
other international markets. We cannot assure you, however, that we can obtain
such approvals on a timely basis or at all.

   For European distribution, we have received ISO 9001/EN46001 certification,
and the EC Certificate pursuant to the European Union Medical Device Directive
93/42/EEC, allowing us to CE Mark our products after assembling appropriate
documentation. ISO 9001/EN46001 certification standards for quality operations
have been developed to ensure that companies know, on a worldwide basis, the
standards of quality to which they will be held. The European Union has
promulgated rules requiring medical products to receive the CE Mark, an
international symbol of quality and compliance with applicable European medical
device directives. Failure to maintain the CE Mark will preclude us from
selling our products in Europe. ISO 9001/EN46001 certification in conjunction
with demonstrated performance to the medical device directive is one of the
alternatives available to meet the CE Mark requirements. We cannot assure you
that we will be successful in maintaining certification requirements.

Product Liability Risk and Insurance Coverage

   The development, manufacture and sale of medical products entail significant
risk of product liability claims. Our current product liability insurance
coverage limits are $7,000,000 per occurrence and $7,000,000 in the aggregate.
We cannot assure you that such coverage limits are adequate to protect us from
any liabilities we might incur in connection with the development, manufacture
and sale of our products. In addition, we may require increased product
liability coverage as products are successfully commercialized in additional
applications. Product liability insurance is expensive and in the future may
not be available to us on acceptable terms, if at all. We have not received any
product liability claims to date. However, a successful product liability claim
or series of claims brought against us in excess of our insurance coverage
could have a material adverse effect on our business, financial condition,
results of operations and prospects.

Employees

   As of July 3, 1999, we had 229 employees of whom 143 were engaged in
manufacturing activities, 23 were engaged in research and development
activities, 30 were engaged in sales and marketing activities, 17 were engaged
in regulatory affairs and quality assurance and 16 were engaged in general and
administrative functions. No employees are covered by collective bargaining
agreements, and we believe we maintain good relations with our employees.

   We are dependent upon a number of key management and technical personnel.
The loss of the services of one or more key employees or consultants could have
a material adverse effect on us. Our success will also depend on our ability to
attract and retain additional highly qualified management and technical
personnel. We face intense competition for qualified personnel, many of whom
often receive competing employment offers. We cannot assure you that we will be
able to attract and retain such personnel. Furthermore, our scientific advisory
board members are all otherwise employed on a full-time basis. As a result, the
scientific advisory board members are not available to devote their full time
or attention to our affairs.

Facilities

   We lease approximately 32,000 square feet in two neighboring buildings in
Sunnyvale, California for administrative offices, general and administrative
purposes, manufacturing facilities and warehousing space. Our two leases for
these facilities will expire in February 2002. We believe that our existing
facilities are adequate for our immediate needs through 1999.

                             PRINCIPAL STOCKHOLDERS

   We have described the "beneficial ownership" of our common stock in the
following tables according to the Securities and Exchange Commission's rules.
Those rules treat a stockholder as owning any shares covered by a stock option,
warrant or other convertible security that the stockholder could exercise
within 60 days after the date of this prospectus, even if they have not
actually been exercised. Such shares, however, are not deemed outstanding for
the purposes of computing the percentage ownership of each other person. Except
as described below, the stockholder listed is the only person who has the
authority to decide how to vote the shares they own, and if and when to sell
those shares, subject to community property laws where applicable.

Common Stock

   The following table sets forth the beneficial ownership of our common stock
as of July 3, 1999:

  . each person who is known by us to beneficially own more than five percent
    of our common stock;

  . each of our current directors and executive officers;

  . all directors and executive officers as a group.

                          DESCRIPTION OF CAPITAL STOCK

   The following description of the material terms of our capital stock is
qualified by reference to our amended and restated certificate of incorporation
and our preferred shares rights agreement, dated as of November 14, 1996, as
amended October 2, 1998. See "Where You Can Find More Information."

   Our authorized capital stock currently consists of 20,000,000 shares of
common stock, par value $0.001 per share, and 5,000,000 shares of preferred
stock, par value $0.001 per share. Each share of our common stock trades with
rights. See "--Rights Plan." As of July 3, 1999, there were outstanding
9,035,886 shares of our common stock and no shares of our Series A preferred
stock.

Common Stock

   Holders of our common stock are entitled to receive dividends or
distributions that are lawfully declared by our board of directors, to have
notice of any authorized meeting of stockholders, and to one vote for each
share of our common stock on all matters which are properly submitted to a vote
of our stockholders. As a Delaware corporation, we are subject to statutory
limitations on the declaration and payment of dividends. In the event of our
liquidation or other dissolution, holders of our common stock will have the
right to a ratable portion of the assets that remain after the full payment of
amounts owed to our creditors, the payment of all our liabilities and the
aggregate liquidation preferences of any outstanding shares of our preferred
stock. The holders of our common stock have no conversion, redemption,
preemptive or cumulative voting rights. All outstanding shares of our common
stock are, and the shares of our common stock to be issued in this offering
will be, validly issued, fully paid and non-assessable.

Preferred Stock

   Our charter authorizes our board of directors to issue preferred stock in
one or more series, to establish the number of shares in any series and to set
the designation and preferences of any series of preferred stock. Our board of
directors is also authorized to set the rights, qualifications, and
restrictions on each series of preferred stock.

   In connection with the adoption of our stockholder rights plan, our board of
directors has designated     shares of preferred stock as Series A
participating preferred stock. The Series A preferred shares purchasable upon
exercise of the rights issuable under the stockholder rights plan will not be
redeemable. Each share of Series A preferred stock will be entitled to an
aggregate dividend of 1,000 times the dividend declared per common share. If we
are liquidated, the holders of the Series A preferred shares will be entitled
to a preferential liquidation payment equal to accrued but unpaid dividends
plus 1,000 times the aggregate per share amount to be distributed with respect
to each share of our common stock. Each Series A preferred share will have
1,000 votes, voting together with the holders of our common stock, except as
required by law or the certificate of designation relating to the Series A
preferred stock. In a merger, consolidation or other transaction in which our
common stock is changed or exchanged, each Series A preferred share will be
entitled to receive 1,000 times the amount received per share of common stock.
These rights are protected by customary anti-dilution provisions. Because of
the nature of the dividend, liquidation and voting rights of the Series A
preferred shares, the value of the one one-thousandth interest in a share of
Series A preferred stock purchasable upon exercise of each Right should
approximate the value of one share of common stock.

Certain Anti-Takeover, Limited Liability and Indemnification Provisions

   Delaware Anti-Takeover Law. We are a Delaware corporation subject to Section
203 of the Delaware General Corporation Law or DGCL. Under Section 203, certain
"business combinations" between a Delaware corporation whose stock generally is
publicly traded or held of record by more than 2,000 stockholders and an
"interested stockholder" are prohibited for a three-year period following the
date that such stockholder became an interested stockholder, unless (i) the
corporation has elected in its certificate of incorporation not to be governed
by Section 203 (we have not made such an election), (ii) the business
combination or the transaction

                                       52
<PAGE>

which resulted in the stockholder becoming an interested stockholder was
approved by the board of directors of the corporation before such stockholder
became an interested stockholder, (iii) upon consummation of the transaction
that made such stockholder an interested stockholder, the interested
stockholder owned at least 85% of the voting stock of the corporation
outstanding at the commencement of the transaction (excluding voting stock
owned by directors who are also officers or held in employee benefit plans in
which the employees do not have a confidential right to tender stock held by
the plan in a tender or exchange offer) or (iv) the business combination is
approved by the board of directors of the corporation and authorized at a
meeting by two-thirds of the voting stock which the interested stockholder did
not own. The three-year prohibition also does not apply to certain business
combinations proposed by an interested stockholder following the announcement
or notification of certain extraordinary transactions involving the corporation
and a person who had not been an interested stockholder during the previous
three years or who became an interested stockholder with the approval of a
majority of the corporation's directors. The term "business combination" is
defined generally to include mergers or consolidations between a Delaware
corporation and an interested stockholder, transactions with an interested
stockholder involving the assets or stock of the corporation or its majority-
owned subsidiaries, and transactions which increase an interested stockholder's
percentage ownership of stock. The term "interested stockholder" is defined
generally as those stockholders who become beneficial owners of 15% or more of
a Delaware corporation's voting stock, together with the affiliates or
associates of that stockholder.

   Limitation of Officer and Director Liability and Indemnification
Arrangements. Our certificate of incorporation provides that an officer or
director of ours will not be personally liable to us or our stockholders for
monetary damages for any breach of his or her fiduciary duty as an officer or
director, except in certain cases where liability is mandated by the DGCL. The
provision has no effect on any non-monetary remedies that may be available to
us or our stockholders, nor does it relieve us or our officers or directors
from compliance with federal or state securities laws. The certificate of
incorporation also generally provides that we shall indemnify, to the fullest
extent permitted by law, any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action, suit,
investigation, administrative hearing or any other proceeding by reason of the
fact that he or she is or was a director or officer of ours, or is or was
serving at our request as a director, officer, employee or agent of another
entity, against expenses incurred by him in connection with such proceeding. An
officer or director shall not be entitled to indemnification by us if (i) the
officer or director did not act in good faith and in a manner reasonably
believed to be in, or not opposed to, our best interests, or (ii) with respect
to any criminal action or proceeding, the officer or director had reasonable
cause to believe his conduct was unlawful.

Transfer Agent and Registrar

   The transfer agent and registrar for our common stock is Norwest Bank
Minnesota, N.A.

Stockholder Rights Plan

   Our board of directors has adopted a stockholder rights plan. The
stockholder rights plan provides for a dividend distribution of one right on
each outstanding share of common stock. Each right entitles stockholders to buy
1/1000th of a share of our Series A participating preferred stock at an
exercise price of $50.00. The rights will become exercisable following the
tenth day after a person or group announces acquisition of 15 percent or more
of our common stock, or announces commencement of a tender offer, the
consummation of which would result in ownership by the person or group of 15
percent or more of our common stock. We will be entitled to redeem the rights
at $0.01 per right at any time on or before the tenth day following acquisition
by a person or group of 15 percent or more of our common stock.

   The stockholder rights plan is designed to assure that our stockholders
receive fair and equal treatment in the event of any proposed takeover of
ArthroCare and to guard against partial tender offers and other abusive tactics
to gain control of ArthroCare without paying all stockholders the fair value of
their shares, including a control premium. We believe that the stockholder
rights plan will permit us to develop our business and foster our long-term
growth without disruptions caused by the threat of a takeover not deemed by our
board to be in

                                       53
<PAGE>

our stockholder's best interests. Generally, the stockholder rights plan will
encourage any potential acquirer to negotiate directly with our board. As a
result, the stockholder rights plan may have the effect of deterring third
parties from making proposals involving an acquisition or change of control of
ArthroCare, although such proposals, if made, might be considered desirable and
beneficial by a majority of our stockholders. The stockholders rights plan
could have the further anti-takeover effect of making it more difficult for
third parties to acquire a majority of our common stock or to cause the
replacement of our board of directors.

</TABLE>

   The representatives have advised us that the underwriters propose to offer
the shares of common stock to the public at the public offering price set forth
on the cover page of this prospectus and to certain dealers at that price less
a concession of not in excess of $     per share, of which $     may be
reallowed to other dealers. After this offering, the public offering price,
concession and reallowance to dealers may be reduced by the representatives. No
such reduction shall change the amount of proceeds to be received by us as set
forth on the cover page of this prospectus. The common stock is offered by the
underwriters as stated herein, subject to receipt and acceptance by them and
subject to their right to reject any order in whole or in part.

   The underwriters have advised us that they do not expect sales to
discretionary accounts to exceed five percent of the total number of shares
offered.

 Over-Allotment Option

   We have granted to the underwriters an option, exercisable during the 30-day
period after the date of this prospectus, to purchase up to 150,000 shares of
common stock at the same price per share as will be paid for the 1,000,000
shares that the underwriters have agreed to purchase. If the underwriters
exercise their over-allotment option to purchase any of the additional 150,000
shares of common stock, the underwriters have severally agreed, subject to
certain conditions, to purchase approximately the same percentage thereof as
the number of shares to be purchased by each of them bears to the total number
of shares of common stock offered in this offering. If purchased, these
additional shares will be sold by the underwriters on the same terms as those
on which the shares offered hereby are being sold. We will be obligated,
pursuant to the over-allotment option, to sell shares to the underwriters to
the extent the over-allotment option is exercised. The underwriters may
exercise the over-allotment option only to cover over-allotments made in
connection with the sale of the shares of common stock offered in this
offering.

   The following table summarizes the compensation to be paid to the
underwriters by us:

 Lock-Up Agreements

   Each of our executive officers and directors have agreed, during the period
of 90 days after the effective date of this prospectus, subject to specified
exceptions, not to offer to sell, contract to sell, or otherwise sell, dispose
of, loan, pledge or grant any rights with respect to any shares of common
stock, any options or warrants to purchase any shares of common stock, or any
securities convertible into or exchangeable for shares of common stock now
owned as of the date of this prospectus or thereafter acquired directly by
those holders or with respect to which they have or thereafter acquire the
power of disposition, without the prior written consent of BancBoston Robertson
Stephens Inc. However, BancBoston Robertson Stephens Inc. may, in its sole
discretion and at any time or from time to time, without notice, release all or
any portion of the securities subject to lock-up agreements.

   In addition, we have agreed that during the lock-up period we will not,
without the prior written consent of BancBoston Robertson Stephens Inc.,
subject to certain exceptions, consent to the disposition of any shares held by
stockholders subject to lock-up agreements prior to the expiration of the lock-
up period, or issue, sell, or otherwise dispose of, any shares of common stock,
any options or warrants to purchase any shares of common stock or any
securities convertible into, exercisable for or exchangeable for shares of
common stock other than our sale of shares in this offering, the issuance of
our common stock upon the exercise of outstanding options or warrants, and the
issuance of options under existing stock option and incentive plans provided
that those options do not vest prior to the expiration of the lock-up period.

 Stabilization

   The representatives have advised us that, pursuant to Regulation M under the
Securities Act of 1933, some persons participating in the offering may engage
in transactions, including stabilizing bids, syndicate covering transactions or
the imposition of penalty bids, that may have the effect of stabilizing or
maintaining the market price of the shares of common stock at a level above
that which might otherwise prevail in the open market. A "stabilizing bid" is a
bid for or the purchase of shares of common stock on behalf of the underwriters
for the purpose of fixing or maintaining the price of the common stock. A
"syndicate covering transaction" is the bid for or purchase of common stock on
behalf of the underwriters to reduce a short position incurred by the
underwriters in connection with the offering. A "penalty bid" is an arrangement
permitting the representatives to reclaim the selling concession otherwise
accruing to an underwriter or syndicate member in connection with the offering
if the common stock originally sold by such underwriter or syndicate member
purchased by the representatives in a syndicate covering transaction and has
therefore not been effectively placed by such underwriter or syndicate member.
The representatives have advised us that such transactions may be effected on
the Nasdaq National Market or otherwise and, if commenced, may be discontinued
at any time.

 Passive Market Making

   In connection with this offering and before the commencement of offers or
sales of the common stock, certain underwriters who are qualified market makers
on the Nasdaq National Market may engage in passive market making transactions
in the common stock on the Nasdaq National Market in accordance with Rule 103
of Regulation M under the Exchange Act, during the business day prior to the
pricing of the offering. Passive market makers must comply with applicable
volume and price limitations and must be identified as such. In general, a
passive market maker must display its bid at a price not in excess of the
highest independent bid for such security; if all independent bids are lowered
below the passive market maker's bid, however, such bid must then be lowered
when certain purchase limits are exceeded.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders
ArthroCare Corporation:

   In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, of stockholders' equity and of cash
flows present fairly, in all material respects, the financial position of
ArthroCare Corporation and its subsidiaries (the "company") at January 3, 1998,
and January 2, 1999, and the results of their operations and their cash flows
for each of the three years in the period ended January 2, 1999, in conformity
with generally accepted accounting principles. These consolidated financial
statements are the responsibility of the company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards, which 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, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for the
opinion expressed above.

                             ARTHROCARE CORPORATION

                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

1. Formation and Business of the Company:

   ArthroCare Corporation (the "company") was incorporated on April 29, 1993.
The company designs, develops, manufactures and markets medical devices for use
in soft-tissue surgery. The company's principal operations commenced in August
1995, at which time it emerged from the development stage.

   On November 22, 1995, 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 2,530,000 shares of common stock (including 330,000 shares
from the exercise of the underwriter's over-allotment option) at $14.00 per
share through an initial public offering in February 1996. Net proceeds (after
underwriter's commissions and fees along with other costs associated with the
offering) totaled $31,857,000. Upon completion of the offering, all outstanding
shares of preferred stock (a total of 8,678,000 shares) were converted into
shares of common stock on a two-for-one basis.

   The company intends to finance its operations primarily through its cash,
cash equivalents and available-for-sale securities, together with future
product sales and licensing fees. There can be no assurance that the company
will not require additional funding or that such funding will be available on
acceptable terms, if at all.

2. Summary of Significant Accounting Policies:

   Basis of Presentation. The company maintains a fifty-two/fifty-three week
fiscal year cycle ending on a Saturday. To conform the company's fiscal year
ends, the company must add a fifty-third week to every fifth or sixth fiscal
year. Accordingly, fiscal 1998 and 1996 were fifty-two week years and fiscal
1997 was a fifty-three week year.

   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 in the financial statements
and accompanying notes. Actual results could differ from those estimates.

   Principles of Consolidation. The consolidated financial statements include
the accounts of ArthroCare and all of its wholly owned subsidiaries. All
significant inter-company transactions and accounts have been eliminated.

   Cash and Cash Equivalents and Available-for-Sale Securities. The company
considers all highly liquid investments purchased with original maturities of
ninety days 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 the
associated premium or discount amortized to "interest income".

   Inventories. Inventories are stated at the lower-of-cost-or-market, with
cost determined on a first-in, first-out basis.

   Property and Equipment. Property and equipment, including equipment under
capital leases, is stated at cost and is depreciated on a straight-line basis
over the estimated useful lives of three to five years. The company places
controllers with customers in order to facilitate the sale of disposables.
Controllers placed with

                             ARTHROCARE CORPORATION

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

customers are capitalized at cost and amortized over a three-year period.
Leasehold improvements are amortized over the shorter of the estimated useful
lives or the lease term. Maintenance and repair costs are charged to operations
as incurred.

   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. Revenue is reported net of a
provision for estimated product returns. The company recognizes revenue from
its business partners upon the completion of certain milestones. The company
recognized license fees of $3.2 million which were received from business
partners during 1998.

   Reclassification. Certain amounts in the prior financial statements have
been reclassified to conform to the current year presentation. These
reclassifications did not impact previously reported total assets, liabilities,
stockholders' equity or net loss.

   Research and Development. Research and development costs are charged to
operations as incurred.

   Foreign Currency Translation. The functional currency of each foreign
subsidiary is its local currency. Essentially all foreign assets and
liabilities are translated into U.S. dollars at year-end exchange rates, while
elements of the income statement are translated at average exchange rates in
effect during the year. Foreign currency transaction gains and losses are
included in the consolidated statement of operations. Adjustments arising from
the translation of net assets located outside the United States (gains and
losses) are recorded as a component of shareholders' equity.

   Concentration of Risks and Uncertainties. Substantially all of the company's
cash and cash equivalents are maintained at financial institutions in the
United States. Deposits at these institutions may exceed the amount of
insurance provided on such deposits. The company has not experienced any losses
on its deposits of cash and cash equivalents.

   The company's Sunnyvale facility currently accounts for all of its product
manufacturing. Disruption of operations at the company's production facility
could cause delays in, or an interruption of, production and shipment of
products which could have a material adverse impact on the company's business,
operating results and financial condition.

   The company purchases certain key components of its products, from sole,
single or limited source suppliers. For some of these components there are few
alternative sources. A reduction or stoppage in supply of sole-source
components would limit the company's ability to manufacture certain products.
There can be no assurance that an alternate supplier could be established if
necessary or that available inventories would be adequate to meet the company's
production needs during any prolonged interruption of supply.

   The company's products require approval from the United States Food and Drug
Administration (FDA) and international regulatory agencies prior to the
commencement of commercial 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 if such approvals were delayed, it would have a
material adverse impact on the company's business.

   Sales to both international and domestic customers are generally made on
open credit terms. Management performs ongoing credit evaluations of the
company's customers and maintains an allowance for potential credit losses when
needed but historically has not experienced any significant losses related to
individual customers or a group of customers in any particular geographic area.

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)


   Fair Value of Financial Instruments. The carrying value of the company's
financial instruments approximate fair value.

   Income Taxes. The company accounts for income taxes under 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.

   Computation of Net Loss per Common Share. Basic and diluted net loss per
common share are computed using the weighted average number of shares of common
stock outstanding. Common equivalent shares from stock options, warrants and
preferred stock of 535,000 shares have been excluded from the computation of
net loss per common share-assuming dilution as their effect is antidilutive. No
additional shares are considered to be outstanding for either computation under
the provisions of SAB No. 98.

   Comprehensive Income (Loss). The company adopted the provision of the
Financial Accounting Standards Board (FASB) SFAS No. 130, "Reporting
Comprehensive Income" in 1998. This statement establishes requirements for
disclosure of comprehensive income with reclassification of earlier financial
statements for comparative purposes. Comprehensive income generally represents
all changes in stockholders' equity except those resulting from investments or
contributions by stockholders.

   Segment Information. In 1998, the company adopted Statement of Financial
Accounting Standard (SFAS) No. 131, "Disclosures about Segments of an
Enterprise and Related Information". SFAS No. 131 supersedes SFAS No. 14,
"Financial Reporting for Segments of a Business Enterprise" replacing the
"industry segment" approach with the "management" approach. The management
approach designates the internal organization that is used by management for
making operating decisions and assessing performance as the source of the
company's reportable segments. SFAS No. 131 also requires disclosures about
products and services, geographic areas, major customers. See Note 11 to the
consolidated financial statements.

   Recent Accounting Pronouncements. In June 1998, the Financial Accounting
Standards Board issued SFAS No. 133, "Accounting for Derivative Instruments and
Hedging Activities". SFAS No. 133 establishes accounting and reporting
standards for derivative instruments, including certain derivative instruments
embedded in other contracts, and for hedging activities. It requires that an
entity recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those instruments at fair value.
The company must adopt this standard no later than fiscal year 2001. To date,
the company does not engage in hedging activities.

3. Available-for-Sale Securities:

   The company's investments consist primarily of corporate notes and bonds
with contractual maturities of less than one year. Gains and losses were
immaterial for all periods presented. At January 2, 1999, the amortized cost of
the investment approximates fair value.

   At January 3, 1998 and January 2, 1999, there were 314,000 and 469,000
options, respectively, exercisable under the 1993 Plan.

   In December 1995, the company adopted the Director Option Plan (Director
Plan) and reserved 100,000 shares of common stock for issuance to directors
under this plan. The plan allows for an initial grant and automatic annual
grants of options to outside directors of the company. As of January 3, 1998
and January 2, 1999 outstanding options under the Director Plan were 24,000 and
33,000, respectively, with 25,875 options exercisable as of January 2, 1999. In
February 1995, pursuant to a restricted stock purchase agreement, 100,000
shares of common stock were purchased by an officer of the company at $0.32 per
share. The restricted stock purchase agreement contains provisions for the
repurchase of common stock by the company in the event of termination of
employment during the four years following the date of the agreement. At
January 2, 1999, 1,667 shares were subject to repurchase under this restricted
stock purchase agreement. Those shares were released from the purchase
restriction in January 1999.

   In August 1995, 90,000 shares of common stock were purchased by an officer
of the company at $0.80 per share pursuant to a restricted stock purchase
agreement. The restricted stock purchase agreement contains provisions for the
repurchase of common stock by the company in the event of termination of
employment during the four years following the date of the agreement. At
January 2, 1999, 10,938 shares were subject to repurchase under this restricted
stock purchase agreement. These shares will continue to be released ratably
over the remaining period.

   Employee Stock Purchase Plan. In December 1995, the company approved the
Employee Stock Purchase Plan and reserved 150,000 shares of common stock for
issuance under this plan. For the years ended January 3, 1998 and January 2,
1999, 16,865 shares and 13,545 shares of common stock were sold under the
Employee Stock Purchase Plan, respectively.

   Warrants. In January 1998, the company issued a warrant to purchase 80,000
shares of common stock at a purchase price of $12.00 per share to certain
foreign employees. The warrant becomes exercisable over a four-year period.

   Stockholders Rights Plan. In November 1996, the Board of Directors approved
a Stockholders Rights Plan declaring a dividend distribution of one Preferred
Share Purchase Right for each outstanding share of the company's Common Stock.
Each right will entitle stockholders to buy one-thousandth of one share of the
company's Series A Participating Preferred Stock at an exercise price of
$50.00. This Plan was designed to assure that the company's stockholders
receive fair and equal treatment in the event of any proposed takeover of the
company and to guard against partial tender offers and other abusive tactics to
gain control of the company without paying all stockholders the fair value of
their shares, including a "control premium".

   Stock-Based Compensation. The company has adopted the disclosure-only
provisions of SFAS No. 123 "Accounting for Stock-Based Compensation" and
continues to account for options granted to employees under APB Opinion No. 25,
"Accounting for Stock Issued to Employees." Had compensation cost for the 1993
Plan, the Director Plan and the Employee Stock Purchase Plan been determined
based on the fair value at the grant date for awards in fiscal year 1996, 1997
and 1998 consistent with the provisions of SFAS No. 123, the company's net loss
per common share and per common share-assuming dilution for the years ended
December 28, 1996, January 3, 1998 and January 2, 1999 would have been
increased to the pro forma amounts indicated below:

   The effects of the pro forma disclosure of applying SFAS No. 123 are not
likely to be representative of the effects of the pro forma disclosures of
future years. Because SFAS No. 123 reflects only options granted after January
1, 1995, the pro forma effect will not be fully reflected until 1999.

   The fair value of each option grant is estimated on the date of grant using
the Black Scholes model with the following weighted average assumptions:

8. Related Parties:

   In connection with the formation of the company, several of the founders and
a partnership of the founders entered into a licensing agreement to facilitate
patent transfers. As a result, the company acquired an exclusive worldwide
perpetual royalty-free license, with right of sublicense, to make, use and sell
products and use patent methods covered by the patent rights limited to
surgical orthopedic and arthroscopic applications.

   Also in connection with its incorporation, the company entered into a
consulting agreement with a consulting and research firm, which is headed by
one of the company's founders. This consulting and research firm was contracted
to perform research related to the development of hand-held instruments used in
arthroscopic procedures. Research and development costs incurred on this
contract in fiscal 1996, 1997 and 1998 were approximately $456,000, $457,000
and $392,000, respectively.

   In January 1995, the company loaned to an officer $120,000 pursuant to a
provision in the officer's employment agreement. The resulting promissory note
bears interest at 6% per annum and is due on the earlier of January 31, 1999 or
termination of employment. In December 1998, the officer paid the note in full.
In February 1995, the company agreed to loan this officer up to an additional
$144,000 in monthly increments of $3,000 at 6% per annum. In December 1997, the
company amended this officer's employment agreement to terminate the increments
effective January 31, 1998 and forgive 10% of the principal and interest at the
end of each fiscal year in which the officer is employed by the company and in
which the company meets certain performance targets. During fiscal year 1997,
$11,000 of principal and interest was forgiven. At January 2, 1999, $99,000 of
principal and interest was outstanding on this note. Both aforementioned notes
are secured by shares of the company's common stock and a mortgage on the
officer's residence and as of February 1999 have been paid in full.

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)


   In December 1995, the company loaned an employee $62,000 pursuant to a
provision in the employee's employment agreement. The resulting promissory note
bears interest at the rate of 6% per annum and is due on the earlier of July
24, 2000 or the termination of employment. The note also permits the company to
loan this employee up to an additional $34,000 in $2,000 monthly increments.
The aforementioned notes are secured by a pledge of this employee's option for
50,000 shares of the company's common stock and any shares issued upon exercise
of such options. In May 1997, all principal and interest were repaid in full.

   In June 1997, the company loaned an officer $500,000 pursuant to a provision
in the officer's employment agreement. The promissory note, which bears no
interest, is secured by a mortgage on the officer's residence and is due and
payable upon either the officer's termination of employment or the sale of the
officer's residence. If the officer is terminated by the company or the company
is acquired, the loan is due and payable within 12 months thereafter. As of
January 2, 1999, $500,000 of principal was outstanding on this note.

   In November 1997, the company issued a relocation loan of $130,000 to an
employee. This loan is secured by the employee's residence and is due and
payable upon either the sale or transfer of the property or the termination of
the officer's employment with the company. As of January 2, 1999, $130,000 of
principal was outstanding on this loan.

9. Income Taxes:

   At January 2, 1999, the company has approximately $18,700,000 and $6,100,000
in federal and state net operating loss carryforwards, respectively, which
expire in the years 2004 through 2018 and 2000 through 2003, respectively.

   The Tax Reform Act of 1986 substantially changed the rates relative to 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 thousands):

   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 since it is more likely than not that a benefit can not be realized
in the future due to the company's recurring operating losses.

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)


10. Employee Benefit Plan:

   The company maintains a Retirement Savings and Investment Plan (401(k) Plan)
which covers substantially all employees. Eligible employees may defer salary
(before tax) up to a specified maximum. The company, at its discretion, may
make matching contributions on behalf of the participants in the 401(k) Plan.
To date, the company has not made any contributions to the 401(k) Plan.

11. Segment Information:

   The company is organized into four segments on the basis of product markets,
Arthroscopy, ENTec(TM), Visage(R) and AngioCare(TM). To date, substantially all
the company's product revenue was related to the Arthroscopic segment. During
fiscal 1998, approximately $2.6 million of the company's license revenue was
attributable to the AngioCare segment, $0.4 million was attributable to the
ENTec segment and $0.3 million was attributable to the Visage segment. Export
sales were approximately $0.9 million during fiscal 1997 and $2.3 million for
fiscal 1998.

12. Business Collaborations:

   During the year ended January 2, 1999, the company formed a new business
division, AngioCare for the purpose of commercializing the company's technology
in the cardiac and interventional cardiology markets. As part of those efforts,
in February 1998, the company entered into a license and OEM agreement under
which Boston Scientific Corporation (BSC) will provide input into the
development of, obtain regulatory approval for and market products based on the
company's CoblationTM technology for myocardial revascularization procedures.
Under the agreement, BSC has paid license fees to the company based upon
achievement of designated milestones and royalties on sales of resulting
products. The first nonrefundable license payment of $3.0 million was received
during 1998 of which $2.6 million was recognized as license revenue.

   In May 1998, the company announced that it had entered the
otorhinolaryngology (ear, nose and throat) market, and that it has formed a new
business unit called ENTec to commercialize the technology in this field. In
June 1998, the company entered into a license and OEM agreement with Xomed
Surgical Products (Xomed) to market the Coblation products in the
otorhinolaryngology market. This agreement was terminated by the company in
February 1999.

13. Subsequent Event:

   In January 1999, the company entered into an exclusive worldwide license and
OEM agreement with Collagen to market and distribute ArthroCare's Coblation-
based product line for cosmetic, dermatologic and aesthetic surgical
applications. On February 8, 1999, the company announced that Collagen had
acquired expanded, exclusive, worldwide rights to market ArthroCare's Cosmetic
Surgery System to all physicians practicing dermatology, and cosmetic and
facial plastic surgery including ear, nose, and throat physicians who perform
such procedures.

14. Event Subsequent to the Date of the Independent Accountant's Report
(Unaudited)

   On February 4, 1999, Xomed Surgical Products of Jacksonville, Florida filed
a complaint against the company in the Fourth Judicial Circuit, Duval County
Florida, alleging breach of contract by the company. In the complaint, Xomed
has demanded a full refund of the amounts paid for certain products bought by
Xomed from the company, and for a portion of an exclusive license fee paid by
Xomed pursuant to an exclusive license and distribution agreement between
Conmed Corporation and the company. This license and distribution agreement was
terminated by the company on February 5, 1999. The company believes that the
suit is without merit, and filed a Motion to Dismiss on February 24, 1999.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (Unaudited)

1. Basis of Presentation:

   In the opinion of management, the accompanying unaudited condensed
consolidated financial statements contain all adjustments (all of which are
normal and recurring in nature) necessary to present fairly the financial
position, results of operations and cash flows of ArthroCare Corporation (the
"company"or "ArthroCare") for the periods indicated. Interim results of
operations are not necessarily indicative of the results to be expected for the
full year or any other interim periods. The notes to the financial statements
contained in the Form 10-K for the year ended January 2, 1999 should be read in
conjunction with these condensed consolidated financial statements. The balance
sheet at January 2, 1999 was derived from audited financial statements;
however, these interim financial statements do not include all disclosures
required by generally accepted accounting principles.

2. Computation of Net Income (Loss) Per Share:

   Basic net income (loss) per share is computed using the weighted average
number of shares of common stock. Diluted net income (loss) per share is
computed using the weighted average number of shares of common stock and common
equivalent shares outstanding during the period. Common equivalent shares
consist of stock options. Common equivalent shares are excluded from the
computation if their effect is anti-dilutive.

   The following is a reconciliation of the computation for basic and diluted
net income (loss) per share (in thousands, except per share data):

5. Line of Credit:

   In June 1999, the company entered into a $7.0 million revolving line of
credit that expires in June 2000. Borrowings under the line of credit bear
interest at the bank's prime rate plus one-quarter of one percentage point.
Borrowings under this line are secured by certain of the company's assets and
are subject to certain covenants related to financial ratios and profits. At
July 3, 1999 the company was in compliance with these covenants. No borrowings
were outstanding as of July 3, 1999.

6. Litigation:

   On February 13, 1998, the company filed a lawsuit against Ethicon, Inc.,
Mitek Surgical Products, a division of Ethicon, Inc., and GyneCare, Inc. ("the
Defendants") in the United States District Court for the Northern District of
California. The lawsuit alleged, among other things, that the Defendants have
been and are

currently infringing four patents issued to the company in December 1997.
Specifically, the Defendants use, market and sell two separate electrosurgical
systems under the names of "VAPR" and "VersaPoint" which the company believes
infringe these patents. The Company settled this patent litigation with the
Defendants on June 24, 1999. Under the terms of the settlement, Ethicon, Inc.
has licensed the company's United States patents in the arthroscopy and
gynecology markets and ArthroCare has dismissed the legal action. Both
companies will remain active in the marketplace. Ethicon, Inc. has paid
ArthroCare a license fee and will pay ongoing royalties on sales in the United
States of certain arthroscopy and gynecology products. The settlement agreement
also establishes a procedure for resolution of certain potential future
intellectual property disputes in these two markets without litigation.

   On February 4, 1999, Xomed Surgical Products ("Xomed") of Jacksonville,
Florida filed a complaint against the company in the Fourth Judicial Circuit,
Duval County, Florida, alleging breach of contract by the company. In the
complaint, Xomed has demanded a full refund of the amounts paid for certain
products bought by Xomed from the company, and for a portion of an exclusive
license fee paid by Xomed pursuant to an exclusive license and distribution
agreement between Xomed and the company. This license and distribution
agreement was terminated by the company on February 5, 1999. The company
believes the suit is without merit, and filed a Motion to Dismiss and Answer to
the Complaint on May 3, 1999. In addition, the company filed two counterclaims
against Xomed for damages caused by Xomed's failure to perform under the
contract and for a certain milestone payment owed to ArthroCare by Xomed.

   On March 24, 1999, a former employee of the Company filed a complaint
against the Company in Santa Clara County Superior Court alleging causes of
action for sexual harassment in violation of the Fair Employment and Housing
Act and retaliation in violation of the Fair Employment and Housing Act. The
Company filed a response to the complaint on June 23, 1999 and had a case
management conference July 27 at which the parties stipulated to mediation.
According to the complaint, the demand exceeds $25,000.

7. Recent Accounting Pronouncements:

   In June 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 133, "Accounting for
Derivative Instruments and Hedging Activities." SFAS No. 133 establishes
accounting and reporting standards for derivative instruments, including
certain derivative instruments embedded in other contracts, and for hedging
activities. It requires that an entity recognize all derivatives as either
assets or liabilities in the statement of financial position and measure those
instruments at fair value. The company must adopt this standard no later than
fiscal year 2001. To date, the company does not engage in hedging activities.

8. Segment Information:

   The company is organized into four business units based on product markets:
arthroscopy, ear nose and throat, cosmetic surgery and cardiology. To date,
substantially all the company's product sales were related to the Arthroscopy
segment. Licensing fees are primarily attributable to the Arthroscopy segment.
However, during the six-month period ended July 3, 1999, approximately $0.3
million of the company's license revenue was attributable to the AngioCare(TM)
segment and $1.0 million was attributable to the Visage(R) segment. During the
six-month period ended July 4, 1998, approximately $2.3 million of the
company's license revenue was attributable to the AngioCare segment.

   The representatives have advised us that the underwriters propose to offer
the shares of common stock to the public at the public offering price set forth
on the cover page of this prospectus and to certain dealers at that price less
a concession of not in excess of $     per share, of which $     may be
reallowed to other dealers. After this offering, the public offering price,
concession and reallowance to dealers may be reduced by the representatives. No
such reduction shall change the amount of proceeds to be received by us as set
forth on the cover page of this prospectus. The common stock is offered by the
underwriters as stated herein, subject to receipt and acceptance by them and
subject to their right to reject any order in whole or in part.

   The underwriters have advised us that they do not expect sales to
discretionary accounts to exceed five percent of the total number of shares
offered.

 Over-Allotment Option

   We have granted to the underwriters an option, exercisable during the 30-day
period after the date of this prospectus, to purchase up to 150,000 shares of
common stock at the same price per share as will be paid for the 1,000,000
shares that the underwriters have agreed to purchase. If the underwriters
exercise their over-allotment option to purchase any of the additional 150,000
shares of common stock, the underwriters have severally agreed, subject to
certain conditions, to purchase approximately the same percentage thereof as
the number of shares to be purchased by each of them bears to the total number
of shares of common stock offered in this offering. If purchased, these
additional shares will be sold by the underwriters on the same terms as those
on which the shares offered hereby are being sold. We will be obligated,
pursuant to the over-allotment option, to sell shares to the underwriters to
the extent the over-allotment option is exercised. The underwriters may
exercise the over-allotment option only to cover over-allotments made in
connection with the sale of the shares of common stock offered in this
offering.

   The following table summarizes the compensation to be paid to the
underwriters by us:

 Indemnity

   The underwriting agreement contains covenants of indemnity among the
underwriters and us against certain civil liabilities, including liabilities
under the Securities Act, and liabilities arising from breaches of
representations and warranties contained in the underwriting agreement.

 Lock-Up Agreements

   Each of our executive officers and directors have agreed, during the period
of 90 days after the effective date of this prospectus, subject to specified
exceptions, not to offer to sell, contract to sell, or otherwise sell, dispose
of, loan, pledge or grant any rights with respect to any shares of common
stock, any options or warrants to purchase any shares of common stock, or any
securities convertible into or exchangeable for shares of common stock now
owned as of the date of this prospectus or thereafter acquired directly by
those holders or with respect to which they have or thereafter acquire the
power of disposition, without the prior written consent of BancBoston Robertson
Stephens Inc. However, BancBoston Robertson Stephens Inc. may, in its sole
discretion and at any time or from time to time, without notice, release all or
any portion of the securities subject to lock-up agreements.

   In addition, we have agreed that during the lock-up period we will not,
without the prior written consent of BancBoston Robertson Stephens Inc.,
subject to certain exceptions, consent to the disposition of any shares held by
stockholders subject to lock-up agreements prior to the expiration of the lock-
up period, or issue, sell, or otherwise dispose of, any shares of common stock,
any options or warrants to purchase any shares of common stock or any
securities convertible into, exercisable for or exchangeable for shares of
common stock other than our sale of shares in this offering, the issuance of
our common stock upon the exercise of outstanding options or warrants, and the
issuance of options under existing stock option and incentive plans provided
that those options do not vest prior to the expiration of the lock-up period.

 Stabilization

   The representatives have advised us that, pursuant to Regulation M under the
Securities Act of 1933, some persons participating in the offering may engage
in transactions, including stabilizing bids, syndicate covering transactions or
the imposition of penalty bids, that may have the effect of stabilizing or
maintaining the market price of the shares of common stock at a level above
that which might otherwise prevail in the open market. A "stabilizing bid" is a
bid for or the purchase of shares of common stock on behalf of the underwriters
for the purpose of fixing or maintaining the price of the common stock. A
"syndicate covering transaction" is the bid for or purchase of common stock on
behalf of the underwriters to reduce a short position incurred by the
underwriters in connection with the offering. A "penalty bid" is an arrangement
permitting the representatives to reclaim the selling concession otherwise
accruing to an underwriter or syndicate member in connection with the offering
if the common stock originally sold by such underwriter or syndicate member
purchased by the representatives in a syndicate covering transaction and has
therefore not been effectively placed by such underwriter or syndicate member.
The representatives have advised us that such transactions may be effected on
the Nasdaq National Market or otherwise and, if commenced, may be discontinued
at any time.

 Passive Market Making

   In connection with this offering and before the commencement of offers or
sales of the common stock, certain underwriters who are qualified market makers
on the Nasdaq National Market may engage in passive market making transactions
in the common stock on the Nasdaq National Market in accordance with Rule 103
of Regulation M under the Exchange Act, during the business day prior to the
pricing of the offering. Passive market makers must comply with applicable
volume and price limitations and must be identified as such. In general, a
passive market maker must display its bid at a price not in excess of the

below the passive market maker's bid, however, such bid must then be lowered

Item 15. Indemnification of Directors and Officers

   Section 145 of the General Corporation Law of the State of Delaware
("Section 145") permits a Delaware corporation to indemnify any person who was
or is a party or is threatened to be made a party to any threatened, pending,
or completed action, suit, or proceeding, whether civil, criminal,
administrative, or investigative (other than an action by or in the right of
the corporation) by reason of the fact that such person is or was a director,
officer, employee, or agent of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee, or agent of
another corporation, partnership, joint venture, trust, or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts
paid in settlement actually and reasonably incurred by such person in
connection with such action, suit, or proceeding if such person acted in good
faith and in a manner such person reasonably believed to be in or not opposed
to the best interests of the corporation, and, with respect to any criminal
action or proceeding, had no reasonable cause to believe such person's conduct
was unlawful.

   In the case of an action by or in the right of the corporation, Section 145
permits the corporation to indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending, or completed action
or suit by or in the right of the corporation to procure a judgment in its
favor by reason of the fact that such person is or was a director, officer,
employee or agent of the corporation, or is or was serving at the request of
the corporation as director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise against
expenses (including attorneys' fees) actually and reasonably incurred by such
person in connection with the defense or settlement of such action or suit if
he acted in good faith and in a manner such person reasonably believed to be
in or not opposed to the best interest of the corporation. No indemnification
may be made in respect of any claim, issue, or matter as to which such person
shall have been adjudged to be liable to the corporation unless and only to
the extent that the Court of Chancery or the court in which such action or
suit was brought shall determine upon application that, despite the
adjudication of liability but in view of all the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses
which the Court of Chancery or such other court shall deem proper.

   To the extent that a present or former director or officer of a corporation
has been successful on the merits or otherwise in defense of any action, suit
or proceeding referred to in the preceding two paragraphs, Section 145
requires that such person be indemnified against expenses (including
attorneys' fees) actually and reasonably incurred by such person in connection
therewith; and that indemnification provided by, or granted pursuant to,

                                     II-1
<PAGE>

Section 145 shall not be deemed exclusive of any other rights to which those
seeking indemnification may be entitled.

   Section 145 provides that expenses (including attorneys' fees) incurred by
an officer or director in defending any civil, criminal, administrative, or
investigative action, suit or proceeding may be paid by the corporation in
advance of the final disposition of such action, suit or proceeding upon
receipt of any undertaking by or on behalf of such director or officer to
repay such amount if it shall ultimately be determined that such person is not
entitled to be indemnified by the corporation as authorized in Section 145.

   Section 145 further empowers the corporation to purchase and maintain
insurance on behalf of any person who 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 and incurred by him in any such capacity, or arising our
of his status as such, whether or not the corporation would have the power to
indemnify him against such liabilities under Section 145.

   Our certificate of incorporation limits the liability of directors for
monetary damages arising from breach of their fiduciary duty to the maximum
extent permitted by the Delaware General Corporate Law ("the Law") and
provides for the indemnification of directors, officers and employees of the
registrant to the fullest extent permitted by the Law.

   Our bylaws also provide we shall indemnify its directors and officers to
the fullest extent permitted by the Law, including circumstances in which
indemnification is otherwise discretionary under the Law.

   We have entered into indemnification agreements with its directors
containing provisions which are in some respects broader than the specific
indemnification provisions contained in the Law. The indemnification
agreements may require us to indemnify its directors against certain
liabilities that may arise by reason of their status or service as directors
(other than liabilities arising from willful misconduct of a culpable nature),
to advance their expenses incurred as a result of any proceeding against them
as to which they could be indemnified, and to obtain director's insurance if
available on reasonable terms.

   We believe that the limitation provision in our certificate of
incorporation and the indemnification provisions in our certificate of
incorporation, bylaws and indemnification agreements will facilitate our
ability to continue to attract and retain qualified individuals to serve as
directors. It is the opinion of the Securities and Exchange Commission that
indemnification provisions such as those contained in the certificate of
incorporation, the bylaws and these agreements have no effect on a directors'
or officers' ability under the federal securities laws. We have also obtained
directors' and officers' liability insurance covering, subject to exceptions,
actions taken by our directors and officers in their capacities as such.

Item 17. Undertakings

   A. Insofar as indemnification for liabilities arising under the Securities
Act of 1933, as amended, may be permitted to directors, officers and
controlling persons of the registrant pursuant to the foregoing provisions, or
otherwise, the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer,
or controlling person of the registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication
of such issue.

   B. The undersigned hereby undertakes that, for purposes of determining any
liability under the Securities Act of 1933, each filing of the registrant's

                               October ___, 1999

BancBoston Robertson Stephens Inc.
Bear Stearns & Co., Inc.
As Representatives of the several Underwriters
c/o BancBoston Robertson Stephens Inc.
555 California Street, Suite 2600
San Francisco, CA 94104

Ladies and Gentlemen:

          Introductory. ArthroCare Corporation, a Delaware corporation (the
"Company), proposes to issue and sell to the several underwriters named in
Schedule A (the "Underwriters") an aggregate of 1,000,000 shares (the "Firm
- ----------
Shares") of its Common Stock, par value $0.001 per share (the "Common Shares").
In addition, the Company has granted to the Underwriters an option to purchase
up to an additional 150,000 Common Shares (the "Option Shares") as provided in
Section 2. The Firm Shares and, if and to the extent such option is exercised,
the Option Shares are collectively called the "Shares". BancBoston Robertson
Stephens Inc. and Bear Stearns & Co., Inc. have agreed to act as representatives
of the several Underwriters (in such capacity, the "Representatives") in
connection with the offering and sale of the Shares.

          The Company has prepared and filed with the Securities and Exchange
Commission (the "Commission") a registration statement on Form S-3
(File No. 333-87187), which contains a form of prospectus to be used in
connection with the public offering and sale of the Shares. Such registration
statement, as amended, including the financial statements, exhibits and
schedules thereto, in the form in which it was declared effective by the
Commission under the Securities Act of 1933 and the rules and regulations
promulgated thereunder (collectively, the "Securities Act"), including all
documents incorporated or deemed to be incorporated by reference therein and any
information deemed to be a part thereof ("Incorporated Documents") at the time
of effectiveness pursuant to Rule 430A or Rule 434 or the Securities Exchange
Act of 1934 and the rules and regulations promulgated thereunder (collectively,
the "Exchange Act"), is called the "Registration Statement". Any registration
statement filed by the Company pursuant to Rule 462(b) under the Securities Act
is called the "Rule 462(b) Registration Statement", and from and after the date
and time of filing of the Rule 462(b) Registration Statement the term
"Registration Statement" shall include the Rule 462(b) Registration Statement.
Such prospectus, in the form first used
<PAGE>

by the Underwriters to confirm sales of the Shares, is called the "Prospectus";
provided, however, if the Company has, with the consent of BancBoston Robertson
Stephens Inc., elected to rely upon Rule 434 under the Securities Act, the term
"Prospectus" shall mean the Company's prospectus subject to completion (each, a
"preliminary prospectus") dated September 30, 1999 (such preliminary prospectus
is called the "Rule 434 preliminary prospectus"), together with the applicable
term sheet (the "Term Sheet") prepared and filed by the Company with the
Commission under Rules 434 and 424(b) under the Securities Act and all
references in this Agreement to the date of the Prospectus shall mean the date
of the Term Sheet. All references in this Agreement to the Registration
Statement, the Rule 462(b) Registration Statement, a preliminary prospectus, the
Prospectus or the Term Sheet, or any amendments or supplements to any of the
foregoing, shall include any copy thereof filed with the Commission pursuant to
its Electronic Data Gathering, Analysis and Retrieval System ("EDGAR"). All
references in this Agreement to financial statements and schedules and other
information which is "contained," "included" or "stated" in the Registration
Statement or the Prospectus (and all other references of like import) shall be
deemed to mean and include all such financial statements and schedules and other
information which is or is deemed to be incorporated by reference in the
Registration Statement or the Prospectus, as the case may be; and all references
in this Agreement to amendments or supplements to the Registration Statement or
the Prospectus shall be deemed to mean and include the filing of any document
under the Exchange Act which is or is deemed to be incorporated by reference in
the Registration Statement or the Prospectus, as the case may be.

                 The Company hereby confirms its agreements with the
Underwriters as follows:

     SECTION 1.  Representations and Warranties of the Company.  The Company
represents, warrants and covenants to each Underwriter as follows:

          (a)    Compliance with Registration Requirements. The Registration
Statement and any Rule 462(b) Registration Statement have been declared
effective by the Commission under the Securities Act. The Company has complied
to the Commission's satisfaction with all requests of the Commission for
additional or supplemental information. No stop order suspending the
effectiveness of the Registration Statement or any Rule 462(b) Registration
Statement is in effect and no proceedings for such purpose have been instituted
or are pending or, to the best knowledge of the Company, are contemplated or
threatened by the Commission.

          Each preliminary prospectus and the Prospectus when filed complied in
all material respects with the Securities Act and, if filed by electronic
transmission pursuant to EDGAR (except as may be permitted by Regulation S-T
under the Securities Act), was identical to the copy thereof delivered to the
Underwriters for use in connection with the offer and sale of the Shares. Each
of the Registration Statement, any Rule 462(b) Registration Statement and any
post-effective amendment thereto, at the time it became effective and at all
subsequent times, complied and will comply in all material respects with the
Securities Act and did not and will not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading. The Prospectus, as
amended or supplemented, as of its date and at all subsequent times, did not and
will not contain any untrue statement of a material fact or omit to state a
material fact necessary in order to make the statements therein, in the light of
the circumstances

                                      -2-
<PAGE>

under which they were made, not misleading. The representations and warranties
set forth in the two immediately preceding sentences do not apply to statements
in or omissions from the Registration Statement, any Rule 462(b) Registration
Statement, or any post-effective amendment thereto, or the Prospectus, or any
amendments or supplements thereto, made in reliance upon and in conformity with
information relating to any Underwriter furnished to the Company in writing by
the Representatives expressly for use therein. There are no contracts or other
documents required by the Securities Act to be described in the Prospectus or to
be filed as exhibits to the Registration Statement which have not been
accurately described in all material respects or filed as required.

          (b) Offering Materials Furnished to Underwriters. The Company has
delivered to the Representatives two complete conformed copy of the Registration
Statement and of each consent and certificate of experts filed as a part
thereof, and conformed copies of the Registration Statement (without exhibits)
and preliminary prospectuses and the Prospectus, as amended or supplemented, in
such quantities and at such places as the Representatives have reasonably
requested for each of the Underwriters.

          (c)    Distribution of Offering Material By the Company. The Company
has not distributed and will not distribute, prior to the later of the Second
Closing Date (as defined below) and the completion of the Underwriters'
distribution of the Shares, any offering material in connection with the
offering and sale of the Shares other than a preliminary prospectus, the
Prospectus or the Registration Statement.

          (d)    The Underwriting Agreement. This Agreement has been duly
authorized, executed and delivered by, and is a valid and binding agreement of,
the Company, enforceable in accordance with its terms, except as rights to
indemnification hereunder may be limited by applicable law and except as the
enforcement hereof may be limited by bankruptcy, insolvency, reorganization,
moratorium or other similar laws relating to or affecting the rights and
remedies of creditors or by general equitable principles.

          (e)    Authorization of the Shares To Be Sold by the Company. The
Shares to be purchased by the Underwriters from the Company have been duly
authorized for issuance and sale pursuant to this Agreement and, when issued and
delivered by the Company pursuant to this Agreement, will be validly issued,
fully paid and nonassessable.

          (f)    No Applicable Registration or Other Similar Rights. There are
no persons with registration or other similar rights to have any equity or debt
securities registered for sale under the Registration Statement or included in
the offering contemplated by this Agreement, except for such rights as have been
duly waived.

          (g)    No Material Adverse Change. Subsequent to the respective dates
as of which information is given in the Prospectus: (i) there has been no
material adverse change, in the condition, financial or otherwise, or in the
earnings, business, operations or prospects, whether or not arising from
transactions in the ordinary course of business, of the Company and its
subsidiaries, considered as one entity (any such change or effect, where the
context so requires, is called a "Material Adverse Change" or a "Material
Adverse Effect"); (ii) the Company and its subsidiaries, considered as one
entity, have not incurred any material liability or obligation, indirect, direct
or contingent,

                                      -3-
<PAGE>

not in the ordinary course of business nor entered into any material transaction
or agreement not in the ordinary course of business; and (iii) there has been no
dividend or distribution of any kind declared, paid or made by the Company or,
except for dividends paid to the Company or other subsidiaries, any of its
subsidiaries on any class of capital stock or repurchase or redemption by the
Company or any of its subsidiaries of any class of capital stock.

          (h)    Independent Accountants. PricewaterhouseCoopers L.L.P., who
have expressed their opinion with respect to the financial statements (which
term as used in this Agreement includes the related notes thereto) and
supporting schedules filed with the Commission as a part of the Registration
Statement and included in the Prospectus, are independent public or certified
public accountants as required by the Securities Act and the Exchange Act.

          (i)    Preparation of the Financial Statements. The financial
statements filed with the Commission as a part of the Registration Statement and
included in the Prospectus present fairly the consolidated financial position of
the Company and its subsidiaries as of and at the dates indicated and the
results of their operations and cash flows for the periods specified. The
supporting schedules included in the Registration Statement present fairly the
information required to be stated therein. Such financial statements and
supporting schedules have been prepared in conformity with generally accepted
accounting principles as applied in the United States applied on a consistent
basis throughout the periods involved, except as may be expressly stated in the
related notes thereto. No other financial statements or supporting schedules are
required to be included in the Registration Statement. The financial data set
forth in the Prospectus under the captions "Prospectus Summary--Summary Selected
Financial Data", "Selected Financial Data" and "Capitalization" fairly present
the information set forth therein on a basis consistent with that of the audited
financial statements contained in the Registration Statement.

          (j)    Company's Accounting System. The Company and each of its
subsidiaries maintain a system of accounting controls sufficient to provide
reasonable assurances that (i) transactions are executed in accordance with
management's general or specific authorizations; (ii) transactions are recorded
as necessary to permit preparation of financial statements in conformity with
generally accepted accounting principles as applied in the United States and to
maintain accountability for assets; (iii) access to assets is permitted only in
accordance with management's general or specific authorization; and (iv) the
recorded accountability for assets is compared with existing assets at
reasonable intervals and appropriate action is taken with respect to any
differences.

          (k)    Subsidiaries of the Company. The Company does not own or
control, directly or indirectly, (i) any corporation, association or other
entity other than the subsidiaries listed in Exhibit 21 to the Company's Annual
Report on Form 10-K for the fiscal year ended January 2, 1999 and (ii) none of
such corporations, associations or other entities identified in subsection (i)
above is a Significant Subsidiary (as that term is defined in Regulation S-X of
the Securities Act).

          (l)    Incorporation and Good Standing of the Company and its
Subsidiaries. Each of the Company and its subsidiaries has been duly organized
and is validly existing as a corporation or limited liability company, as the
case may be, in good

                                      -4-
<PAGE>

standing under the laws of the jurisdiction in which it is organized with full
corporate power and authority to own its properties and conduct its business as
described in the prospectus, and is duly qualified to do business as a foreign
corporation and is in good standing under the laws of each jurisdiction which
requires such qualification, except where the failure to be so qualified or be
in good standing would not have a Material Adverse Effect.

          (m)    Capitalization of the Subsidiaries. All the outstanding shares
of capital stock of each subsidiary have been duly and validly authorized and
issued and are fully paid and nonassessable, and, except as otherwise set forth
in the Prospectus, all outstanding shares of capital stock of the subsidiaries
are owned by the Company either directly or through wholly owned subsidiaries
free and clear of any security interests, claims, liens or encumbrances.

          (n)    No Prohibition on Subsidiaries from Paying Dividends or Making
Other Distributions. No subsidiary of the Company is currently prohibited,
directly or indirectly, from paying any dividends to the Company, from making
any other distribution on such subsidiary's capital stock, from repaying to the
Company any loans or advances to such subsidiary from the Company or from
transferring any of such subsidiary's property or assets to the Company or any
other subsidiary of the Company, except as described in or contemplated by the
Prospectus.

          (o)    Capitalization and Other Capital Stock Matters. The authorized,
issued and outstanding capital stock of the Company is as set forth in the
Prospectus under the caption "Capitalization" as of the date set forth therein
(other than for subsequent issuances, if any, pursuant to employee benefit plans
described in the Prospectus or upon exercise of outstanding options or warrants
described in the Prospectus). The Common Shares (including the Shares) conform
in all material respects to the description thereof contained in the Prospectus.
All of the issued and outstanding Common Shares have been duly authorized and
validly issued, are fully paid and nonassessable and have been issued in
compliance with federal and state securities laws. None of the outstanding
Common Shares were issued in violation of any preemptive rights, rights of first
refusal or other similar rights to subscribe for or purchase securities of the
Company. There are no authorized or outstanding options, warrants, preemptive
rights, rights of first refusal or other rights to purchase, or equity or debt
securities convertible into or exchangeable or exercisable for, any capital
stock of the Company or any of its subsidiaries other than those accurately
described in the Prospectus. The description of the Company's stock option,
stock bonus and other stock plans or arrangements, and the options or other
rights granted thereunder, set forth in the Prospectus accurately and fairly
presents the information required to be shown with respect to such plans,
arrangements, options and rights.

          (p)    Stock Exchange Listing. The Shares are registered pursuant to
[Section 12(b) or 12(g)] of the Securities Exchange Act of 1934 (the "Exchange
Act") and are listed on the Nasdaq National Market, and the Company has taken no
action designed to, or likely to have the effect of, terminating the
registration of the Common Shares under the Exchange Act or delisting the Common
Shares from the Nasdaq National Market, nor has the Company received any
notification that the Commission, the National Association of Securities
Dealers, LLC (the "NASD") or the Nasdaq National Market is contemplating
terminating such registration or listing.

                                      -5-
<PAGE>

          (q)    No Consents, Approvals or Authorizations Required. No consent,
approval, authorization, filing with or order of any court or governmental
agency or regulatory body is required in connection with the transactions
contemplated herein including, without limitation, the Food and Drug
Administration (the "FDA"), except such as have been obtained or made under the
Securities Act and such as may be required (i) under the blue sky laws of any
jurisdiction in connection with the purchase and distribution of the Shares by
the Underwriters in the manner contemplated here and in the Prospectus, (ii) by
the National Association of Securities Dealers, L.L.C. and (iii) by the federal
and provincial laws of Canada.

          (r)    Non-Contravention of Existing Instruments Agreements. Neither
the issue and sale of the Shares nor the consummation of any other of the
transactions herein contemplated nor the fulfillment of the terms hereof will
conflict with, result in a breach or violation or imposition of any lien, charge
or encumbrance upon any property or assets of the Company or any of its
subsidiaries pursuant to, (i) the charter or by-laws of the Company or any of
its subsidiaries, (ii) the terms of any material indenture, contract, lease,
mortgage, deed of trust, note agreement, loan agreement or other agreement,
obligation, condition, covenant or instrument to which the Company or any of its
subsidiaries is a party or bound or to which its or their property is subject or
(iii) any statute, law, rule, regulation, judgment, order or decree applicable
to the Company or any of its subsidiaries of any court, regulatory body,
administrative agency, governmental body, arbitrator or other authority having
jurisdiction over the Company or any of its subsidiaries or any of its or their
properties.

          (s)    No Defaults or Violations. Neither the Company nor any
subsidiary is in violation or default of (i) any provision of its charter or by-
laws, (ii) the terms of any indenture, contract, lease, mortgage, deed of trust,
note agreement, loan agreement or other agreement, obligation, condition,
covenant or instrument to which it is a party or bound or to which its property
is subject or (iii) any statute, law, rule, regulation, judgment, order or
decree of any court, regulatory body, administrative agency, governmental body,
arbitrator or other authority having jurisdiction over the Company or such
subsidiary or any of its properties, as applicable, except any such violation or
default which would not, singly or in the aggregate, result in a Material
Adverse Change except as otherwise disclosed in the Prospectus.

          (t)    No Actions, Suits or Proceedings. Except as otherwise disclosed
in the Prospectus, no action, suit or proceeding by or before any court or
governmental agency, authority or body or any arbitrator involving the Company
or any of its subsidiaries or its or their property is pending or, to the best
knowledge of the Company, threatened that (i) could reasonably be expected to
have a Material Adverse Effect on the performance of this Agreement or the
consummation of any of the transactions contemplated hereby or (ii) could
reasonably be expected to result in a Material Adverse Effect.

          (u)    All Necessary Permits, Etc. Except as otherwise disclosed in
the Prospectus, the Company and each subsidiary possess such valid and current
material certificates, authorizations or permits issued by the appropriate
state, federal or foreign regulatory agencies or bodies necessary to conduct
their respective businesses as currently conducted including, without
limitation, the FDA, and neither the Company nor any subsidiary has received any
notice of proceedings relating to the revocation or modification of, or non-
compliance with, any such certificate, authorization or permit

                                      -6-
<PAGE>

which, singly or in the aggregate, if the subject of an unfavorable decision,
ruling or finding, could result in a Material Adverse Change.

          (v)    Title to Properties. The Company and each of its subsidiaries
has good and marketable title to all the properties and assets reflected as
owned in the financial statements referred to in Section 1 (i) above (or
elsewhere in the Prospectus), in each case free and clear of any security
interests, mortgages, liens, encumbrances, equities, claims and other defects,
except such as do not materially and adversely affect the value of such property
and do not materially interfere with the use made or proposed to be made of such
property by the Company or such subsidiary. The real property, improvements,
equipment and personal property held under lease by the Company or any
subsidiary are held under valid and enforceable leases, except as rights to
indemnification thereunder may be limited by applicable law and except as the
enforcement thereof may be limited by bankruptcy, insolvency, reorganization,
moratorium or other similar laws relating to or affecting the rights and
remedies of creditors or by general equitable principles. With such exceptions
as are not material and do not materially interfere with the use made or
proposed to be made of such real property, improvements, equipment or personal
property by the Company or such subsidiary.

          (w)    Tax Law Compliance. The Company and its consolidated
subsidiaries have filed all necessary federal, state and foreign income and
franchise tax returns and have paid all taxes required to be paid by any of them
and, if due and payable, any related or similar assessment, fine or penalty
levied against any of them. The Company has made adequate charges, accruals and
reserves in the applicable financial statements referred to in Section 1(i)
above in respect of all federal, state and foreign income and franchise taxes
for all periods as to which the tax liability of the Company or any of its
consolidated subsidiaries has not been finally determined. The Company is not
aware of any tax deficiency that has been or might be asserted or threatened
against the Company that could result in a Material Adverse Change.

          (x) Intellectual Property Rights. Each of the Company and its
subsidiaries owns all patents, patent rights, inventions, trade secrets, know-
how, trademarks, service marks, trade names and copyrights or possesses adequate
rights to use all licenses which are necessary to conduct its businesses as now
or as proposed to be conducted by it as described in the Registration Statement
and Prospectus and any as now or as proposed to be conducted by it Incorporated
Document; the expiration of any patents, patent rights, trade secrets,
trademarks, service marks, trade names or copyrights would not result in a
Material Adverse Change that is not otherwise disclosed in the Prospectus; the
Company has not received any notice of, and has no knowledge of, any
infringement of or conflict with asserted rights of the Company by others with
respect to any patent, patent rights, inventions, trade secrets, know-how,
trademarks, service marks, trade names or copyrights; and the Company has not
received any notice of, and has no knowledge of, any infringement of or conflict
with asserted rights of others with respect to any patent, patent rights,
inventions, trade secrets, know-how, trademarks, service marks, trade names or
copyrights which, singly or in the aggregate, if the subject of an unfavorable
decision, ruling or finding, might have a Material Adverse Change. To the
Company's knowledge, none of the patent rights owned or licensed by the Company
are unenforceable or invalid. The Company has duly and properly filed or caused
to be filed with the United States Patent and Trademark Office (the "PTO") and
appropriate foreign and international patent authorities all patent applications
described or referred to in the Prospectus and as set forth on Schedule B, and
has complied with

the PTO's duty of candor and disclosure for each of the United States patent
applications set forth on Schedule B; the Company is unaware of any facts which
would preclude their grant of a patent from each of the patent applications set
forth on Schedule B; the Company has no knowledge of any facts which would
preclude it from having clear title to its patent applications referenced in the
Prospectus. The Company is not aware of the granting of any patent rights to
third parties or the filing of patent applications by third parties or any other
rights to any of the Company's Intellectual Property.

          (y)    Year 2000 Preparedness. There are no issues related to the
Company's, or any of its subsidiaries', preparedness for the Year 2000 that (i)
are of a character required to be described or referred to in the Registration
Statement or Prospectus or any Incorporated Document by the Securities Act or by
the Exchange Act or the rules and regulations of the Commission thereunder which
have not been accurately described in the Registration Statement or Prospectus
or any Incorporated Document or (ii) might reasonably be expected to result in
any Material Adverse Change or that might materially affect their properties,
assets or rights. Except as set forth in the Prospectus, all internal computer
systems and each Constituent Component (as defined below) of those systems and
all computer-related products and each Constituent Component (as defined below)
of those products of the Company and each of its subsidiaries fully comply with
Year 2000 Qualification Requirements. "Year 2000 Qualifications Requirements"
means that the internal computer systems and each Constituent Component (as
defined below) of those systems and all computer-related products and each
Constituent Component (as defined below) of those products of the Company and
each of its Subsidiaries (i) have been reviewed to confirm that they store,
process (including sorting and performing mathematical operations, calculations
and computations), input and output data containing date and information
correctly regardless of whether the date contains dates and times before, on or
after January 1, 2000, (ii) have been designated to ensure date and time entry
recognition and calculations, and date data interface values that reflect the
century, (iii) accurately manage and manipulate data involving dates and times,
including single century formulas and multi-century formulas, and will not cause
an abnormal ending scenario within the application or generate incorrect values
or invalid results involving such dates, (iv) accurately process any date
rollover, and (v) accept and respond to two-digit year date input in a manner
that resolves any ambiguities as to the century. "Constituent Component" means
all software (including operating systems, programs, packages and utilities),
firmware, hardware, networking components, and peripherals provided as part of
the configuration. Except as set forth in the Prospectus, the Company has
inquired of material vendors as to their preparedness for the Year 2000 and has
disclosed in the Registration Statement or Prospectus any issues that might
reasonably be expected to result in any Material Adverse Change .

          (z)    No Transfer Taxes or Other Fees. There are no transfer taxes or
other similar fees or charges under Federal law or the laws of any state, or any
political subdivision thereof, required to be paid in connection with the
issuance and sale by the Company of the shares.

          (aa)   Company Not an "Investment Company". The Company has been
advised of the rules and requirements under the Investment Company Act of 1940,
as amended (the "Investment Company Act"). The Company is not, and after receipt
of payment for the Shares will not be, an "investment company" or an entity
"controlled" by an "investment company" within the meaning of the Investment
Company Act and will

                                      -8-
<PAGE>

conduct its business in a manner so that it will not become subject to the
Investment Company Act.

          (bb)   Insurance. Each of the Company and its subsidiaries are insured
by recognized, financially sound and reputable institutions with policies in
such amounts and with such deductibles and covering such risks as are generally
deemed adequate and customary for their businesses including, but not limited
to, policies covering real and personal property owned or leased by the Company
and its subsidiaries against theft, damage, destruction, acts of vandalism and
earthquakes, general liability and Directors and Officers liability. The Company
has no reason to believe that it or any subsidiary will not be able (i) to renew
its existing insurance coverage as and when such policies expire or (ii) to
obtain comparable coverage from similar institutions as may be necessary or
appropriate to conduct its business as now conducted and at a cost that would
not result in a Material Adverse Change. Neither of the Company nor any
subsidiary has been denied any insurance coverage which it has sought or for
which it has applied.

          (cc)   Labor Matters. To the best of Company's knowledge, no labor
disturbance by the employees of the Company or any of its subsidiaries exists or
is imminent; and the Company is not aware of any existing or imminent labor
disturbance by the employees of any of its principal suppliers, value added
resellers, subcontractors, original equipment manufacturers, authorized dealers
or international distributors that might be expected to result in a Material
Adverse Change.

          (dd)   No Price Stabilization or Manipulation. The Company has not
taken and will not take, directly or indirectly, any action designed to or that
might be reasonably expected to cause or result in stabilization or manipulation
of the price of the Common Stock to facilitate the sale or resale of the Shares.

          (ee)   Lock-Up Agreements. Each officer and director of the company
has agreed to sign an agreement substantially in the form attached hereto as
Exhibit A (the "Lock-up Agreements").  The Company has provided to counsel for
- ---------
the Underwriters a complete and accurate list of all securityholders of the
Company and the number and type of securities held by each securityholder as of
June 30, 1999. The Company has provided to counsel for the Underwriters true,
accurate and complete copies of all of the Lock-up Agreements presently in
effect or effected hereby Except as contemplated by the letter agreement between
the Representatives and Hira Thapliyal dated September 15, 1999, the Company
represents and warrants that it will not release any of its officers, directors
or other stockholders from any Lock-up Agreements currently existing or
hereafter effected without the prior written consent of BancBoston Robertson
Stephens Inc.

          (ff)   Related Party Transactions. There are no business relationships
or related-party transactions involving the Company or any subsidiary or any
other person required to be described in the Prospectus which have not been
described as required.

          (gg)   No Unlawful Contributions or Other Payments. Except as
otherwise disclosed in the Prospectus, neither the Company nor any of its
subsidiaries nor, to the best of the Company's knowledge, any employee or agent
of the Company or any subsidiary, has made any contribution or other payment to
any official of, or candidate

                                      -9-
<PAGE>

for, any federal, state or foreign office in violation of any law or of the
character required to be disclosed in the Prospectus.

          (hh)   Environmental Laws. Except as otherwise disclosed in the
Prospectus, (i) the Company is in compliance with all rules, laws and
regulations relating to the use, treatment, storage and disposal of toxic
substances and protection of health or the environment ("Environmental Laws")
which are applicable to its business, except where the failure to comply would
not result in a Material Adverse Change, (ii) the Company has received no notice
from any governmental authority or third party of an asserted claim under
Environmental Laws, which claim is required to be disclosed in the Registration
Statement and the Prospectus and any Incorporated Document, (iii) the Company
will not be required to make future material capital expenditures to comply with
Environmental Laws and (iv) no property which is owned, leased or occupied by
the Company has been designated as a Superfund site pursuant to the
Comprehensive Response, Compensation, and Liability Act of 1980, as amended (42
U.S.C. (S) 9601, et seq.), or otherwise designated as a contaminated site under
                 -- ---
applicable state or local law.

          (ii)   Periodic Review of Costs of Environmental Compliance. In the
ordinary course of its business, the Company conducts a periodic review of the
effect of Environmental Laws on the business, operations and properties of the
Company and its subsidiaries, in the course of which it identifies and evaluates
associated costs and liabilities (including, without limitation, any capital or
operating expenditures required for clean-up, closure of properties or
compliance with Environmental Laws or any permit, license or approval, any
related constraints on operating activities and any potential liabilities to
third parties). On the basis of such review and the amount of its established
reserves, the Company has reasonably concluded that such associated costs and
liabilities would not, individually or in the aggregate, result in a Material
Adverse Change.

          (jj)   ERISA Compliance. Except as otherwise disclosed in the
Prospectus, the Company and its subsidiaries and any "employee benefit plan" (as
defined under the Employee Retirement Income Security Act of 1974, as amended,
and the regulations and published interpretations thereunder (collectively,
"ERISA")) established or maintained by the Company, its subsidiaries or their
"ERISA Affiliates" (as defined below) are in compliance in all material respects
with ERISA. "ERISA Affiliate" means, with respect to the Company or a
subsidiary, any member of any group of organizations described in Sections
414(b),(c),(m) or (o) of the Internal Revenue Code of 1986, as amended, and the
regulations and published interpretations thereunder (the "Code") of which the
Company or such subsidiary is a member. No "reportable event" (as defined under
ERISA) has occurred or is reasonably expected to occur with respect to any
"employee benefit plan" established or maintained by the Company, its
subsidiaries or any of their ERISA Affiliates. No "employee benefit plan"
established or maintained by the Company, its subsidiaries or any of their ERISA
Affiliates, if such "employee benefit plan" were terminated, would have any
"amount of unfounded benefit liabilities" (as defined under ERISA). Neither the
Company, its subsidiaries nor any of their ERISA Affiliates has incurred or
reasonably expects to incur any liability under (i) Title IV of ERISA with
respect to termination of, or withdrawal from, any "employee benefit plan" or
(ii) Sections 412, 4971, 4975 or 4980B of the Code. Each "employee benefit plan"
established or maintained by the Company, its subsidiaries or any of their ERISA
Affiliates that is intended to be qualified under Section 401(a) of the Code is
so

                                      -10-
<PAGE>

qualified and nothing has occurred, whether by action or failure to act, which
would cause the loss of such qualification.

          (kk)   Exchange Act Compliance. The documents incorporated or deemed
to be incorporated by reference in the Prospectus, at the time they were or
hereafter are filed with the Commission, complied and will comply in all
material respects with the requirements of the Exchange Act, and, when read
together with the other information in the Prospectus, at the time the
Registration Statement and any amendments thereto become effective and at the
First Closing Date and the Second Closing Date, as the case may be, will not
contain an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

          (ll)   Exchange Act Reports Filed. The Company has filed all reports
required to be filed pursuant to the Securities Act and the Exchange Act.

          (mm)   Conditions for Use of Form S-3. The Company has satisfied the
conditions for the use of Form S-3, as set forth in the general instructions
thereto, with respect to the Registration Statement.

     Any certificate signed by an officer of the Company and delivered to the
Representative or to counsel for the Underwriters shall be deemed to be a
representation and warranty by the Company to each Underwriter as to the matters
set forth therein.

     Section 2.  Purchase, Sale and Delivery of the Shares.

          (a)    The Firm Shares. The Company agrees to issue and sell to the
several Underwriters the Firm Shares upon the terms herein set forth. On the
basis of the representations, warranties and agreements herein contained, and
upon the terms but subject to the conditions herein set forth, the Underwriters
agree, severally and not jointly, to purchase from the Company the respective
number of Firm Shares set forth opposite their names on Schedule A. The purchase
                                                        ----------
price per Firm Share to be paid by the several Underwriters to the Company shall
be $[___] per share.

          (b)    The First Closing Date. Delivery of the Firm Shares to be
purchased by the Underwriters and payment therefor shall be made by the Company
and the Representative at 6:00 a.m. San Francisco time, at the offices of Latham
& Watkins (or at such other place as may be agreed upon among the
Representatives and the Company), (i) on the third (3/rd/) full business day
following the first day that Shares are traded, (ii) if this Agreement is
executed and delivered after 1:30 P.M., San Francisco time, the fourth (4/th/)
full business day following the day that this Agreement is executed and
delivered or (iii) at such other time and date not later that seven (7) full
business days following the first day that Shares are traded as the
Representative and the Company may determine (or at such time and date to which
payment and delivery shall have been postponed pursuant to Section 8 hereof),
such time and date of payment and delivery being herein called the "Closing
Date;" provided, however, that if the Company has not made available to the
Representatives copies of the Prospectus within the time provided in Section
4(d) hereof, the Representatives may, in their sole discretion, postpone the
Closing Date until no later that two (2) full business days following delivery
of copies of the Prospectus to the Representative.

                                      -11-
<PAGE>

          (c)    The Option Shares; the Second Closing Date. In addition, on the
basis of the representations, warranties and agreements herein contained, and
upon the terms but subject to the conditions herein set forth, the Company
hereby grants an option to the several Underwriters to purchase, severally and
not jointly, up to an aggregate of 150,000 Option Shares from the Company at the
purchase price per share to be paid by the Underwriters for the Firm Shares. The
option granted hereunder is for use by the Underwriters solely in covering any
over-allotments in connection with the sale and distribution of the Firm Shares.
The option granted hereunder may be exercised at any time upon notice by the
Representatives to the Company, which notice may be given at any time within 30
days from the date of this Agreement. The time and date of delivery of the
Option Shares, if subsequent to the First Closing Date, is called the "Second
Closing Date" and shall be determined by the Representatives and shall not be
earlier than three nor later than five full business days after delivery of such
notice of exercise. If any Option Shares are to be purchased, each Underwriter
agrees, severally and not jointly, to purchase the number of Option Shares
(subject to such adjustments to eliminate fractional shares as the
Representatives may determine) that bears the same proportion to the total
number of Option Shares to be purchased as the number of Firm Shares set forth
on Schedule A opposite the name of such Underwriter bears to the total number of
   ----------
Firm Shares. The Representatives may cancel the option at any time prior to its
expiration by giving written notice of such cancellation to the Company.

          (d)    Public Offering of the Shares. The Representatives hereby
advise the Company that the Underwriters intend to offer for sale to the public,
as described in the Prospectus, their respective portions of the Shares as soon
after this Agreement has been executed and the Registration Statement has been
declared effective as the Representatives, in their sole judgment, have
determined is advisable and practicable.

          (e)    Payment for the Shares. Payment for the Shares shall be made at
the First Closing Date (and, if applicable, at the Second Closing Date) by wire
transfer in immediately available-funds to the order of the Company.

          It is understood that the Representatives have been authorized, for
their own account and the accounts of the several Underwriters, to accept
delivery of and receipt for, and make payment of the purchase price for, the
Firm Shares and any Option Shares the Underwriters have agreed to purchase.
BancBoston Robertson Stephens Inc., individually and not as a Representative of
the Underwriters, may (but shall not be obligated to) make payment for any
Shares to be purchased by any Underwriter whose funds shall not have been
received by the Representatives by the First Closing Date or the Second Closing
Date, as the case may be, for the account of such Underwriter, but any such
payment shall not relieve such Underwriter from any of its obligations under
this Agreement.

          (f)    Delivery of the Shares. The Company shall deliver, or cause to
be delivered, a credit representing the Firm Shares to an account or accounts at
The Depository Trust Company, as designated by the Representatives for the
accounts of the Representatives and the several Underwriters at the First
Closing Date, against the irrevocable release of a wire transfer of immediately
available funds for the amount of the purchase price therefor. The Company shall
also deliver, or cause to be delivered a credit representing the Option Shares
the Underwriters have agreed to purchase at the First Closing Date (or the
Second Closing Date, as the case may be), to an account or accounts at The
Depository Trust Company as designated by the Representatives for

                                      -12-
<PAGE>

the accounts of the Representative and the several Underwriters, against the
irrevocable release of a wire transfer of immediately available funds for the
amount of the purchase price therefor. Time shall be of the essence, and
delivery at the time and place specified in this Agreement is a further
condition to the obligations of the Underwriters.

          (g)    Delivery of Prospectus to the Underwriters. Not later than
12:00 noon on the second business day following the date the Shares are released
by the Underwriters for sale to the public, the Company shall deliver or cause
to be delivered copies of the Prospectus in such quantities and at such places
as the Representatives shall request.

     SECTION 3.  Covenants of the Company. The Company further covenants and
agrees with each Underwriter as follows:

          (a)    Registration Statement Matters. The Company will (i) use its
best efforts to cause the Registration Statement to become effective or, if the
procedure in Rule 430A of the Securities Act is followed, to prepare and timely
file with the Commission under Rule 424(b) under the Securities Act a Prospectus
in a form approved by the Representatives containing information previously
omitted at the time of effectiveness of the Registration Statement in reliance
on Rule 430A of the Securities Act and (ii) not file any amendment to the
Registration Statement or supplement to the Prospectus of which the
Representatives shall not previously have been advised and furnished with a copy
or to which the Representatives shall have reasonably objected in writing, or
subject however, to compliance with the Securities Act. If the Company elects to
rely on Rule 462(b) under the Securities Act, the Company shall file a Rule
462(b) Registration Statement with the Commission in compliance with Rule 462(b)
under the Securities Act prior to the time confirmations are sent or given, as
specified by Rule 462(b)(2) under the Securities Act, and shall pay the
applicable fees in accordance with Rule 111 under the Securities Act.

          (b)    Securities Act Compliance. The Company will advise the
Representatives promptly (i) when the Registration Statement or any post-
effective amendment thereto shall have become effective, (ii) of receipt of any
comments from the Commission, (iii) of any request of the Commission for
amendment of the Registration Statement or for supplement to the Prospectus or
for any additional information and (iv) of the issuance by the Commission of any
stop order suspending the effectiveness of the Registration Statement or the use
of the Prospectus or of the institution of any proceedings for that purpose. The
Company will use its best efforts to prevent the issuance of any such stop order
preventing or suspending the use of the Prospectus and to obtain as soon as
possible the lifting thereof, if issued.

          (c)    Blue Sky Compliance. The Company will cooperate with the
Representatives and counsel for the Underwriters in endeavoring to qualify the
Shares for sale under the securities laws of such jurisdictions (both national
and foreign) as the Representative may reasonably have designated in writing and
will make such applications, file such documents, and furnish such information
as may be reasonably required for that purpose, provided the Company shall not
be required to qualify as a foreign corporation or to file a general consent to
service of process in any jurisdiction where it is not now so qualified or
required to file such a consent. The Company will, from time to time, prepare
and file such statements, reports and other documents, as are

                                      -13-
<PAGE>

or may be required to continue such qualifications in effect for so long a
period as the Representatives may reasonably request for distribution of the
Shares.

          (d)    Amendments and Supplements to the Prospectus and Other
Securities Act Matters. The Company will comply with the Securities Act and the
rules and regulations of the Commission thereunder, so as to permit the
completion of the distribution of the Shares as contemplated in this Agreement
and the Prospectus. If during the period in which a prospectus is required by
law to be delivered by an Underwriter or dealer, any event shall occur as a
result of which, in the judgment of the Company or in the reasonable opinion of
the Representatives or counsel for the Underwriters, it becomes necessary to
amend or supplement the Prospectus in order to make the statements therein, in
the light of the circumstances existing at the time the Prospectus is delivered
to a purchaser, not misleading, or, if it is necessary at any time to amend or
supplement the Prospectus to comply with any law, the Company promptly will
prepare and file with the Commission, and furnish at its own expense to the
Underwriters and to dealers, an appropriate amendment to the Registration
Statement or supplement to the Prospectus so that the Prospectus as so amended
or supplemented will not, in the light of the circumstances when it is so
delivered, be misleading, or so that the Prospectus will comply with the law.

          (e)    Copies of any Amendments and Supplements to the Prospectus. The
Company agrees to furnish the Representatives, without charge, during the period
beginning on the date hereof and ending on the later of the First Closing Date
or such date, as in the opinion of counsel for the Underwriters, the Prospectus
is no longer required by law to be delivered in connection with sales by an
Underwriter or dealer (the "Prospectus Delivery Period"), as many copies of the
Prospectus and any amendments and supplements thereto (including any documents
incorporated or deemed incorporated by reference therein) as the Representatives
may reasonably request.

          (f)    Insurance. The Company shall obtain Directors and Officers
liability insurance in the minimum amount of $10 million which shall apply to
the offering contemplated hereby.

          (g)    Notice of Subsequent Events. If at any time during the ninety
(90) day period after the Registration Statement becomes effective, any,
publication or event relating to or affecting the Company shall occur as a
result of which in your opinion the market price of the Company Shares has been
or is likely to be materially affected (regardless of whether such publication
or event necessitates a supplement to or amendment of the Prospectus), the
Company will, after written notice from you advising the Company to the effect
set forth above, forthwith prepare, consult with you concerning the substance of
and disseminate a press release or other public statement, reasonably
satisfactory to you, responding to or commenting on such publication or event.

          (h)    Use of Proceeds. The Company shall apply the net proceeds from
the sale of the Shares sold by it in the manner described under the caption "Use
of Proceeds" in the Prospectus.

                                      -14-
<PAGE>

          (i)    Transfer Agent. The Company shall engage and maintain, at its
expense, a registrar and transfer agent (which may be the same entity as the
registrar) for the Company Shares.

          (j)    Earnings Statement. As soon as practicable, the Company will
make generally available to its security holders and to the Representative an
earnings statement (which need not be audited) covering the twelve-month period
ending _____ that satisfies the provisions of Section 11(a) of the Securities
Act.

          (k)    Periodic Reporting Obligations. During the Prospectus Delivery
Period the Company shall file, on a timely basis, with the Commission and the
Nasdaq National Market all reports and documents required to be filed under the
Exchange Act.

          (l)    Agreement Not to Offer or Sell Additional Securities. The
Company will not, without the prior written consent of BancBoston Robertson
Stephens Inc., for a period of 90 days following the date of the Prospectus,
offer, sell or contract to sell, or otherwise dispose of or enter into any
transaction which is designed to, or could be expected to, result in the
disposition (whether by actual disposition or effective economic disposition due
to cash settlement or otherwise by the Company or any affiliate of the Company
or any person in privity with the Company or any affiliate of the Company)
directly or indirectly, or announce the offering of, any other Common Shares or
any securities convertible into, or exchangeable for, Common Shares; provided,
however, that the Company may (i) issue and sell Common Shares pursuant to any
director or employee stock option plan, stock ownership plan or dividend
reinvestment plan of the Company in effect at the date of the Prospectus and
described in the Prospectus in the ordinary course of business so long as none
of those shares held by persons subject to lock-up agreements may be transferred
on during the period of 90 days from the date that the Registration Statement is
declared effective (the "Lock-Up Period") and the Company shall enter stop
transfer instructions with its transfer agent and registrar against the transfer
of any such Common Shares and (ii) the Company may issue Common Shares issuable
upon the conversion of securities or the exercise of warrants outstanding at the
date of the Prospectus and described in the Prospectus.

          (m)    Future Reports to the Representative. During the period of five
years hereafter the Company will furnish to the Representatives (i) as soon as
practicable after the end of each fiscal year, copies of the Annual Report of
the Company containing the balance sheet of the Company as of the close of such
fiscal year and statements of income, stockholders' equity and cash flows for
the year then ended and the opinion thereon of the Company's independent public
or certified public accountants; (ii) as soon as practicable after the filing
thereof, copies of each proxy statement, Annual Report on Form 10-K, Quarterly
Report on Form 10-Q, Current Report on Form 8-K or other report filed by the
Company with the Commission, the National Association of Securities Dealers, LLC
or any securities exchange; and (iii) as soon as available, copies of any report
or communication of the Company mailed generally to holders of its capital
stock.

          (n)    Exchange Act Compliance. During the Prospectus Delivery Period,
the Company will file all documents required to be filed with the Commission
pursuant to Section 13, 14 or 15 of the Exchange Act in the manner and within
the time periods required by the Exchange Act.

Closing Date and the Second Closing Date, as the case may be, a certificate of
the Company, dated the First Closing Date or the Second Closing Date, as the

information is given in the Registration Statement and Prospectus, there has not
been (a) any Material Adverse Change, (b) any transaction that is material to
the Company and its

                                      -18-

order to evidence the accuracy of any of the representations and warranties, or

terminated by the Representatives pursuant to Section 4, Section 8 or Section 9,
or if the sale to the Underwriters of the Shares on the First Closing Date is

the Company agrees to reimburse the Representatives and the other Underwriters
(or such Underwriters as have terminated this Agreement with respect to
themselves), severally, upon demand for all out-of-pocket expenses that shall
have been reasonably incurred by the Representatives and the Underwriters in
connection with the proposed purchase and the offering and sale of the Shares,
including but not limited to fees and disbursements of counsel, printing
expenses, travel expenses, postage, facsimile and telephone charges.

     SECTION 7.  Indemnification and Contribution.

          (a)    Indemnification of the Underwriters. The Company agrees to
indemnify and hold harmless each Underwriter, its officers and employees, and
each person, if any, who controls any Underwriter within the meaning of the
Securities Act and the Exchange Act against any loss, claim, damage, liability
or expense, as incurred, to which such Underwriter or such controlling person
may become subject, under the Securities Act, the Exchange Act or other federal
or state statutory law or regulation, or at common law or otherwise (including
in settlement of any litigation, if such settlement is effected with the written
consent of the Company, which consent shall not be unreasonably withheld),
insofar as such loss, claim, damage, liability or expense (or actions in respect
thereof as contemplated below) arises out of or is based (i) upon any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement, or any amendment thereto, including any information
deemed to be a part thereof pursuant to Rule 430A or Rule 434 under the
Securities Act, or the omission or alleged omission therefrom of a material fact
required to be stated therein or necessary to make the statements therein not
misleading; or (ii) upon any untrue statement or alleged untrue statement of a
material fact contained in any preliminary prospectus or the Prospectus (or any
amendment or supplement thereto), or the

                                      -20-
<PAGE>

omission or alleged omission therefrom of a material fact necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading; or (iii) in whole or in part upon any inaccuracy in
the representations and warranties of the Company contained herein; or (iv) in
whole or in part upon any failure of the Company to perform its obligations
hereunder or under law; or (v) any act or failure to act or any alleged act or
failure to act by any Underwriter in connection with, or relating in any manner
to, the Shares or the offering contemplated hereby, and which is included as
part of or referred to in any loss, claim, damage, liability or action arising
out of or based upon any matter covered by clause (i), (ii), (iii) or (iv)
above, provided that the Company shall not be liable under this clause (v) to
the extent that a court of competent jurisdiction shall have determined by a
final judgment that such loss, claim, damage, liability or action resulted
directly from any such acts or failures to act undertaken or omitted to be taken
by such Underwriter through its bad faith or willful misconduct; and to
reimburse each Underwriter and each such controlling person for any and all
expenses (including the fees and disbursements of counsel chosen by BancBoston
Robertson Stephens Inc.) as such expenses are reasonably incurred by such
Underwriter or such controlling person in connection with investigating,
defending, settling, compromising or paying any such loss, claim, damage,
liability, expense or action; provided, however, that the foregoing indemnity
agreement shall not apply to any loss, claim, damage, liability or expense to
the extent, but only to the extent, arising out of or based upon any untrue
statement or alleged untrue statement or omission or alleged omission made in
reliance upon and in conformity with written information furnished to the
Company by the Representatives expressly for use in the Registration Statement,
any preliminary prospectus or the Prospectus (or any amendment or supplement
thereto); and provided, further, that with respect to any preliminary
prospectus, the foregoing indemnity agreement shall not inure to the benefit of
any Underwriter from whom the person asserting any loss, claim, damage,
liability or expense purchased Shares, or any person controlling such
Underwriter, if copies of the Prospectus were timely delivered to the
Underwriter pursuant to Section 2 and a copy of the Prospectus (as then amended
or supplemented if the Company shall have furnished any amendments or
supplements thereto) was not sent or given by or on behalf of such Underwriter
to such person, if required by law so to have been delivered, at or prior to the
written confirmation of the sale of the Shares to such person, and if the
Prospectus (as so amended or supplemented) would have cured the defect giving
rise to such loss, claim, damage, liability or expense. The indemnity agreement
set forth in this Section 7(a) shall be in addition to any liabilities that the
Company may otherwise have.

          (b)    Indemnification of the Company, its Directors and Officers.
Each Underwriter agrees, severally and not jointly, to indemnify and hold
harmless the Company, each of its directors, each of its officers who signed the
Registration Statement and each person, if any, who controls the Company within
the meaning of the Securities Act or the Exchange Act, against any loss, claim,
damage, liability or expense, as incurred, to which the Company, or any such
director, officer or controlling person may become subject, under the Securities
Act, the Exchange Act, or other federal or state statutory law or regulation, or
at common law or otherwise (including in settlement of any litigation, if such
settlement is effected with the written consent of such Underwriter), insofar as
such loss, claim, damage, liability or expense (or actions in respect thereof as
contemplated below) arises out of or is based upon any untrue or alleged untrue
statement of a material fact contained in the Registration Statement, any
preliminary prospectus or the Prospectus (or any amendment or supplement
thereto), or arises out of or is based upon the omission or alleged omission to
state therein a material fact

                                      -21-
<PAGE>

required to be stated therein or necessary to make the statements therein not
misleading, in each case to the extent, but only to the extent, that such untrue
statement or alleged untrue statement or omission or alleged omission was made
in the Registration Statement, any preliminary prospectus, the Prospectus (or
any amendment or supplement thereto), in reliance upon and in conformity with
written information furnished to the Company by the Representatives expressly
for use therein; and to reimburse the Company, or any such director, officer or
controlling person for any legal and other expense reasonably incurred by the
Company, or any such director, officer or controlling person in connection with
investigating, defending, settling, compromising or paying any such loss, claim,
damage, liability, expense or action. The indemnity agreement set forth in this
Section 7(b) shall be in addition to any liabilities that each Underwriter may
otherwise have.

          (c)    Information Provided by the Underwriters. The Company hereby
acknowledges that the only information that the Underwriters have furnished to
the Company expressly for use in the Registration Statement, any preliminary
prospectus or the Prospectus (or any amendment or supplement thereto) are the
statements set forth in the table in the second paragraph and the third
paragraph under the caption "Underwriting" in the Prospectus; and the
Underwriters confirm that such statements are correct.

          (d)    Notifications and Other Indemnification Procedures. Promptly
after receipt by an indemnified party under this Section 7 of notice of the
commencement of any action, such indemnified party will, if a claim in respect
thereof is to be made against an indemnifying party under this Section 7, notify
the indemnifying party in writing of the commencement thereof, but the omission
so to notify the indemnifying party will not relieve it from any liability which
it may have to any indemnified party for contribution or otherwise than under
the indemnity agreement contained in this Section 7 or to the extent it is not
prejudiced as a proximate result of such failure. In case any such action is
brought against any indemnified party and such indemnified party seeks or
intends to seek indemnity from an indemnifying party, the indemnifying party
will be entitled to participate in, and, to the extent that it shall elect,
jointly with all other indemnifying parties similarly notified, by written
notice delivered to the indemnified party promptly after receiving the aforesaid
notice from such indemnified party, to assume the defense thereof with counsel
reasonably satisfactory to such indemnified party; provided, however, if the
defendants in any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that a conflict may arise between the positions of the indemnifying party and
the indemnified party in conducting the defense of any such action or that there
may be legal defenses available to it and/or other indemnified parties which are
different from or additional to those available to the indemnifying party, the
indemnified party or parties shall have the right to select separate counsel to
assume such legal defenses and to otherwise participate in the defense of such
action on behalf of such indemnified party or parties. Upon receipt of notice
from the indemnifying party to such indemnified party of such indemnifying
party's election so to assume the defense of such action and approval by the
indemnified party of counsel, the indemnifying party will not be liable to such
indemnified party under this Section 7 for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof unless (i) the indemnified party shall have employed separate counsel in
accordance with the proviso to the next preceding sentence (it being understood,
however, that the indemnifying party shall not be liable for the expenses of
more than one separate counsel (together

                                      -22-
<PAGE>

with local counsel), approved by the indemnifying party (BancBoston Robertson
Stephens Inc. in the case of Section 7(b) and Section 8), representing the
indemnified parties who are parties to such action), (ii) the indemnifying party
shall not have employed counsel satisfactory to the indemnified party to
represent the indemnified party within a reasonable time after notice of
commencement of the action, or (iii) the indemnifying party has authorized the
employment of counsel for the indemnified party at the expense of the
indemnifying party, in each of which cases the fees and expenses of counsel
shall be at the expense of the indemnifying party.

          (e)    Settlements. The indemnifying party under this Section 7 shall
not be liable for any settlement of any proceeding effected without its written
consent, which consent shall not be unreasonably withheld, but if settled with
such consent or if there be a final judgment for the plaintiff, the indemnifying
party agrees to indemnify the indemnified party against any loss, claim, damage,
liability or expense by reason of such settlement or judgment. Notwithstanding
the foregoing sentence, if at any time an indemnified party shall have requested
an indemnifying party to reimburse the indemnified party for fees and expenses
of counsel as contemplated by Section 7(d) hereof, the indemnifying party agrees
that it shall be liable for any settlement of any proceeding effected without
its written consent if (i) such settlement is entered into more than 30 days
after receipt by such indemnifying party of the aforesaid request and (ii) such
indemnifying party shall not have reimbursed the indemnified party in accordance
with such request prior to the date of such settlement. No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement, compromise or consent to the entry of judgment in any pending or
threatened action, suit or proceeding in respect of which any indemnified party
is or could have been a party and indemnity was or could have been sought
hereunder by such indemnified party, unless such settlement, compromise or
consent includes (i) an unconditional release of such indemnified party from all
liability on claims that are the subject matter of such action, suit or
proceeding and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act by or on behalf of any indemnified party.

          (f)    Contribution. If the indemnification provided for in this
Section 7 is unavailable to or insufficient to hold harmless an indemnified
party under Section 7(a) or (b) above in respect of any losses, claims, damages
or liabilities (or actions or proceedings in respect thereof) then each
indemnifying party shall contribute to the aggregate amount paid or payable by
such indemnified party in such proportion as is appropriate to reflect the
relative benefits received by the Company on the one hand and the Underwriters
on the other from the offering of the Shares. If, however, the allocation
provided by the immediately preceding sentence is not permitted by applicable
law then each indemnifying party shall contribute to such amount paid or payable
by such indemnified party in such proportion as is appropriate to reflect not
only such relative benefits but also the relative fault of the Company on the
one hand and the Underwriters on the other in connection with the statements or
omissions which resulted in such losses, claims, damages or liabilities, (or
actions or proceedings in respect thereof), as well as any other relevant
equitable considerations. The relative benefits received by the Company on the
one hand and the Underwriter on the other shall be deemed to be in the same
proportion as the total net proceeds from the offering (before deducting
expenses) received by the Company bears to the total underwriting discounts and
commissions received by the Underwriters, in each case as set forth in the table
on the cover page of the Prospectus. The relative fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or

                                      -23-
<PAGE>

the omission or alleged omission to state a material fact relates to information
supplied by the Company on the one hand or the Underwriters on the other and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

          The Company and Underwriters agree that it would not be just and
equitable if contributions pursuant to this Section 7(f) were determined by pro
rata allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to above in this Section 7(f). The amount paid
or payable by an indemnified party as a result of the losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) referred to above in
this Section 7(f) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
subsection (f), (i) no Underwriter shall be required to contribute any amount in
excess of the underwriting discounts and commissions applicable to the Shares
purchased by such Underwriter and (ii) no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Underwriters' obligations in this Section 7(f)
to contribute are several in proportion to their respective underwriting
obligations and not joint.

          (g) Timing of Any Payments of Indemnification. Any losses, claims,
damages, liabilities or expenses for which an indemnified party is entitled to
indemnification or contribution under this Section 7 shall be paid by the
indemnifying party to the indemnified party as such losses, claims, damages,
liabilities or expenses are incurred, but in all cases, no later than thirty
(30) days of invoice to the indemnifying party.

          (h) Survival. The indemnity and contribution agreements contained in
this Section 7 and the representation and warranties of the Company set forth in
this Agreement shall remain operative and in full force and effect, regardless
of (i) any investigation made by or on behalf of any Underwriter or any person
controlling any Underwriter, the Company, its directors or officers or any
persons controlling the Company, (ii) acceptance of any Shares and payment
therefor hereunder, and (iii) any termination of this Agreement. A successor to
any Underwriter, or to the Company, its directors or officers, or any person
controlling the Company, shall be entitled to the benefits of the indemnity,
contribution and reimbursement agreements contained in this Section 7.

          (i) Acknowledgements of Parties. The parties to this Agreement hereby
acknowledge that they are sophisticated business persons who were represented by
counsel during the negotiations regarding the provisions hereof including,
without limitation, the provisions of this Section 7, and are fully informed
regarding said provisions. They further acknowledge that the provisions of this
Section 7 fairly allocate the risks in light of the ability of the parties to
investigate the Company and its business in order to assure that adequate
disclosure is made in the Registration Statement and Prospectus as required by
the Securities Act and the Exchange Act.

     Section 8. Default of One or More of the Several Underwriters. If, on the
First Closing Date or the Second Closing Date, as the case may be, any one or
more of the several Underwriters shall fail or refuse to purchase Shares that it
or they have agreed to purchase hereunder on such date, and the aggregate number
of Common

                                      -24-
<PAGE>

Shares which such defaulting Underwriter or Underwriters agreed but failed or
refused to purchase does not exceed 10% of the aggregate number of the Shares to
be purchased on such date, the other Underwriters shall be obligated, severally,
in the proportions that the number of Firm Common Shares set forth opposite
their respective names on Schedule A bears to the aggregate number of Firm
                          ----------
Shares set forth opposite the names of all such non-defaulting Underwriters, or
in such other proportions as may be specified by the Representative with the
consent of the non-defaulting Underwriters, to purchase the Shares which such
defaulting Underwriter or Underwriters agreed but failed or refused to purchase
on such date. If, on the First Closing Date or the Second Closing Date, as the
case may be, any one or more of the Underwriters shall fail or refuse to
purchase Shares and the aggregate number of Shares with respect to which such
default occurs exceeds 10% of the aggregate number of Shares to be purchased on
such date, and arrangements satisfactory to the Representative and the Company
for the purchase of such Shares are not made within 48 hours after such default,
this Agreement shall terminate without liability of any party to any other party
except that the provisions of Sections 4, 5 and 7 shall at all times be
effective and shall survive such termination. In any such case either the
Representatives or the Company shall have the right to postpone the First
Closing Date or the Second Closing Date, as the case may be, but in no event for
longer than seven days in order that the required changes, if any, to the
Registration Statement and the Prospectus or any other documents or arrangements
may be effected.

          As used in this Agreement, the term "Underwriter" shall be deemed to
include any person substituted for a defaulting Underwriter under this Section
8. Any action taken under this Section 8 shall not relieve any defaulting
Underwriter from liability in respect of any default of such Underwriter under
this Agreement.

     Section 9. Termination of this Agreement. Prior to the First Closing Date,
this Agreement may be terminated by the Representatives by notice given to the
Company if at any time (i) trading or quotation in any of the Company's
securities shall have been suspended or limited by the Commission or by the
Nasdaq Stock Market, or trading in securities generally on either the Nasdaq
Stock Market or the New York Stock Exchange shall have been suspended or
limited, or minimum or maximum prices shall have been generally established on
any of such stock exchanges by the Commission or the National Association of
Securities Dealers, LLC; (ii) a general banking moratorium shall have been
declared by any of federal, New York or California authorities; (iii) there
shall have occurred any outbreak or escalation of national or international
hostilities or any crisis or calamity, or any change in the United States or
international financial markets, or any substantial change or development
involving a prospective change in United States' or international political,
financial or economic conditions, as in the judgment of the Representatives is
material and adverse and makes it impracticable or inadvisable to market the
Common Shares in the manner and on the terms described in the Prospectus or to
enforce contracts for the sale of securities; (iv) in the judgment of the
Representatives there shall have occurred any Material Adverse Change; or (v)
the Company shall have sustained a loss by strike, fire, flood, earthquake,
accident or other calamity of such character as in the judgment of the
Representatives may interfere materially with the conduct of the business and
operations of the Company regardless of whether or not such loss shall have been
insured. Any termination pursuant to this Section 9 shall be without liability
on the part of (a) the Company to any Underwriter, except that the Company shall
be obligated to reimburse the expenses of the Representative and the
Underwriters pursuant to Sections 5 and 6 hereof, (b) any

                                      -25-
<PAGE>

Underwriter to the Company, or (c) of any party hereto to any other party except
that the provisions of Section 7 shall at all times be effective and shall
survive such termination.

     Section 10. Representations and Indemnities to Survive Delivery. The
respective indemnities, agreements, representations, warranties and other
statements of the Company, of its officers and of the several Underwriters set
forth in or made pursuant to this Agreement will remain in full force and
effect, regardless of any investigation made by or on behalf of any Underwriter
or the Company or any of its or their partners, officers or directors or any
controlling person, as the case may be, and will survive delivery of and payment
for the Shares sold hereunder and any termination of this Agreement.

     Section 11. Notices. All communications hereunder shall be in writing and
shall be mailed, hand delivered or telecopied and confirmed to the parties
hereto as follows:

process or other legal summons for purposes of any such suit, action or
proceeding that may be instituted in any state or federal court in the City and

     RE: ArthroCare Corporation (the "Company")

Ladies & Gentlemen:

     The undersigned is an owner of record or beneficially of certain shares of
Common Stock of the Company ("Common Stock") or securities convertible into or
exchangeable or exercisable for Common Stock. The Company proposes to carry out
a public offering of Common Stock (the "Offering") for which you will act as the
representatives (the "Representatives") of the underwriters. The undersigned
recognizes that the Offering will be of benefit to the undersigned and will
benefit the Company by, among other things, raising additional capital for its
operations. The undersigned acknowledges that you and the other underwriters are
relying on the representations and agreements of the undersigned contained in
this letter in carrying out the Offering and in entering into underwriting
arrangements with the Company with respect to the Offering.

     In consideration of the foregoing, the undersigned hereby agrees that the
undersigned will not offer to sell, contract to sell, or otherwise sell, dispose
of, loan, pledge or grant any rights with respect to (collectively, a
"Disposition") any shares of Common Stock, any options or warrants to purchase
any shares of Common Stock or any securities convertible into or exchangeable
for shares of Common Stock (collectively, "Securities") now owned or hereafter
acquired directly by such person or with respect to which such person has or
hereafter acquires the power of disposition, otherwise than (i) as a bona fide
gift or gifts, provided the donee or donees thereof agree in writing to be bound
by this restriction, (ii) as a distribution to partners or shareholders of such
person, provided that the distributees thereof agree in writing to be bound by
the terms of this restriction, (iii) with respect to sales or purchases of
Common Stock acquired on the open market or (iv) with the prior written consent
of BancBoston Robertson Stephens Inc., for a period commencing on the date
hereof and continuing to a date 90 days after the Registration Statement is
declared effective by the Securities and Exchange Commission (the "Lock-up
Period"). The foregoing restriction has been expressly agreed to preclude the
holder of the Securities from engaging in any hedging or other transaction which
is designed to or reasonably expected to lead to or result in a Disposition of
Securities during the Lock-up Period, even if such Securities would be disposed
of by someone other than such holder. Such prohibited hedging or other
transactions would include, without limitation, any short sale (whether or not
against the box) or any purchase, sale or grant of any right (including, without
limitation, any put or call option) with respect to any Securities or with
respect to any security (other than a broad-

                                      A-1
<PAGE>

based market basket or index) that included, relates to or derives any
significant part of its value from Securities. The undersigned also agrees and
consents to the entry of stop transfer instructions with the Company's transfer
agent and registrar against the transfer of shares of Common Stock or Securities
held by the undersigned except in compliance with the foregoing restrictions.

     This agreement is irrevocable and will be binding on the undersigned and
the respective successors, heirs, personal representatives, and assigns of the
undersigned.

     In the event that the Registration Statement shall not have been declared
effective on or before December 31, 1999 this Lock-Up Agreement shall be of no
further force or effect.

authority to own, lease and operate its properties and to conduct its business

such counsel's knowledge, the Company does not own or control, directly or
indirectly, any corporation, association or other entity other than [list
subsidiaries];

(iv)   The authorized, issued and outstanding capital stock of the Company is as

subject to any preemptive right, co-sale right, registration right, right of
first refusal or other similar right;

(v)    All issued and outstanding shares of capital stock of each Significant
Subsidiary of the Company have been duly authorized and validly issued and are
fully paid and nonassessable, and, to such counsel's knowledge, have not been
issued in violation of or subject to any preemptive right, co-sale right,
registration right, right of first refusal or other similar right and are owned
by the Company free and clear of any pledge, lien, security interest,
encumbrance, claim or equitable interest;

and will not have been issued in violation of or subject to any preemptive
right, co-sale right, registration right, right of first refusal or other
similar right.

regulations of the Commission thereunder;

(xii)   The information in the Prospectus under the caption "Description of

securities of the Company and, except as set forth in the Registration Statement
and Prospectus, all holders of securities of the Company having rights known to
such counsel to registration of such shares of Company Shares or other
securities because of the filing of the Registration Statement by the Company
have, with respect to the offering contemplated thereby, waived such rights or
such rights have expired by reason of lapse of time following notification of
the Company's intent to file the Registration Statement or have included
securities in the Registration Statement pursuant to the exercise of and in full
satisfaction of such rights.

in conferences with officials and other representatives of the Company, the
Representatives, Underwriters' Counsel and the independent certified public
accountants of the Company, at which such conferences the contents of the
Registration Statement and Prospectus and related matters were discussed, and
although they have not verified the accuracy or completeness of the statements
contained in the Registration Statement or the Prospectus, nothing has come to
the attention of such counsel which leads them to believe that, at the time the
Registration Statement became effective and at all times subsequent thereto up
to and on the First Closing Date or Second Closing Date, as the case may be, the
Registration Statement and any amendment or supplement thereto and any
Incorporated Document, when such documents became effective or were filed with
the Commission (other than the financial statements including supporting
schedules and other financial and statistical information derived therefrom, as
to which such counsel need express no comment) contained any untrue statement of
a material fact or omitted to state a material fact required to be stated
therein or necessary to make the statements therein not misleading, or at the
First Closing Date or the Second Closing Date, as the case may be, the
Registration Statement, the Prospectus and any amendment or supplement thereto
and any Incorporated Document (except as aforesaid) contained any untrue
statement of a material fact or omitted to state a material fact necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading. Such counsel shall also state that the conditions for
the use of Form S-3 set forth in the General Instructions thereto have been
satisfied.

schedule to such opinion (the "Foreign Patents") and each of the applications
listed on a schedule to such opinion (the "Foreign Applications"). Such counsel
knows of no claims of third parties to any ownership interest or lien with
respect to the Foreign Patents or Foreign Applications. Such counsel is not
aware of any material defect of form in the preparation or filing of the Foreign
Applications on behalf of the Company. To the knowledge of such counsel, the
Foreign Applications are being pursued by the Company. To the knowledge of such
counsel, the Company owns as its sole property the Foreign Patents and pending
Foreign Applications;

               (iii) Such counsel knows of no reason why the Patents or Foreign
Patents are not valid as issued. Such counsel has no knowledge of any reason why
any patent to be issued as a result of any Application or Foreign Application
would not be valid or would not afford the Company useful patent protection with
respect thereto;

               (iv) As to the statements under the captions "Risk Factors --
Dependence on Patents and Proprietary Rights," and "Business -- Patents and
Proprietary Rights," nothing has come to the attention of such counsel which
caused them to believe that the above-mentioned sections of the Registration
Statement, at the time the Registration Statement became effective and at all
times subsequent thereto up to and on the Closing Date and on any later date on
which Option Stock are to be purchased the Registration Statement and any
amendment or supplement thereto made available and reviewed by such counsel
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated

Closing Date or any later date on which the Option Stock are to be purchased, as
the case may be, the above-mentioned sections of the Registration Statement,
Prospectus and any amendment or supplement thereto made available and reviewed
by such counsel contained any untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading; and

               (v)  Such counsel knows of no material action, suit, claim or
proceeding relating to patents, patent rights or licenses, trademarks or
trademark rights, copyrights, collaborative research, licenses or royalty
arrangements or agreements or trade secrets, know-how or proprietary techniques,
including processes and substances, owned by or affecting the business or

                          Regulatory Counsel Opinion

           Such counsel are familiar with the government regulations affecting
the Company in its business and have read the Registration Statement and the
Prospectus, including particularly the portions of the Registration Statement
and the Prospectus referring to government regulations and:

     (i)   Such counsel is of the opinion that the statements summarizing
applicable provisions of the Federal Food, Drug and Cosmetic Act (the "FDCA")
and implementing regulations included in the Prospectus under the captions "Risk
Factors--We must obtain government clearances or approvals before we can sell
our products; we must continue to comply with applicable laws and regulations,"
and "Business--Government Regulation" (the "Regulatory Information"), are
accurate in all material respects and do not omit to summarize applicable
provisions of the FDCA and implementing regulations necessary to make such
statements contained therein not misleading.

     (ii) In addition, such counsel shall state that such counsel has
participated in conferences with officials and other representatives of the
Company, at which such conferences the Regulatory Information and related
matters were discussed, and although they have not verified the accuracy or
completeness of the statements contained in the Registration Statement or the
Prospectus, nothing has come to the attention of such counsel which caused them
to believe that the Regulatory Information at the time the Registration
Statement became effective and at all times subsequent thereto up to and on the
Closing Date and on any later date on which Option Stock are to be purchased the
Registration Statement and any amendment or supplement thereto made available
and reviewed by counsel contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein in light of the circumstances under which they were
made, not misleading or at the Closing Date or any later date on which the
Option Stock are to be purchased, as the case may be, the above-mentioned
sections of the Registration Statement, Prospectus and any amendment or
supplement thereto made available and reviewed by such counsel contained any
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary to make the statements therein, in light of

     payment therefor in accordance with the terms of the Underwriting
     Agreement, will be validly issued, fully paid and non-assessable.

     (ii)   The Registration Statement complied as to form in all material
     respects with the requirements of the Act; the Registration Statement has

     order proceedings with respect thereto have been instituted or threatened
     or are pending under the Act.

     (iii)  The Underwriting Agreement has been duly authorized, executed and

Registration Statement and any amendment or supplement thereto and any
Incorporated Document, when such documents became effective or were filed with
