(1) Equals the aggregate principal amount of the notes being registered.
    Estimated solely for purposes of calculating the registration fee pursuant
    to Rule 457(o) under the Securities Act.

(2) Represents the number of shares of common stock, including the associated

    of the notes. Pursuant to Rule 416 under the Securities Act, the registrant
    is also registering such indeterminate number of shares of common stock,
    including the associated preferred share purchase rights, as may be issued
    from time to time upon conversion of the notes as a result of the
    antidilution provisions relating to the notes. No additional consideration
    will be received for the common stock or the associated preferred share
    purchase rights, and therefore no registration fee is required pursuant to
    Rule 457(i).

PROSPECTUS

                                  $180,000,000

                                   RESMED INC.

                   4% CONVERTIBLE SUBORDINATED NOTES DUE 2006
          SHARES OF COMMON STOCK ISSUABLE UPON CONVERSION OF THE NOTES

     In June and July, 2000, we issued and sold $180,000,000 aggregate principal
amount of our 4% Convertible Subordinated Notes Due 2006 in a private offering.
This prospectus will be used by selling securityholders to resell the notes and
the common stock issuable upon conversion of the notes. Interest on the notes is
payable in arrears on June 20 and December 20 of each year, beginning on
December 20, 2001. The notes mature on June 20, 2006 unless earlier converted or
redeemed. The notes are general unsecured indebtedness and are subordinated to
all of our existing and future senior indebtedness. The indenture governing the
notes does not limit the incurrence by us or our subsidiaries of senior
indebtedness or other indebtedness.

     The notes are convertible, at the option of the holder, at any time on or
prior to maturity, into shares of common stock of ResMed Inc. The notes are
convertible at a conversion price of $60.60 per share, which is equal to a
conversion rate of 16.5017 shares per $1,000 principal amount of notes, subject
to adjustment. Our common stock is traded on the New York Stock Exchange under
the symbol "RMD." On September 27, 2001, the last reported sale price of the
common stock on the New York Stock Exchange was $52.10 per share.

     We may redeem some or all of the notes at any time before June 20, 2004 at
a redemption price of $1,000 per $1,000 principal amount of notes, plus accrued
and unpaid interest, if any, to the redemption date, if the closing price of our
common stock has exceeded 150% of the conversion price then in effect for at
least 20 trading days within a period of 30 consecutive trading days ending on
the trading day before the date of mailing of the provisional redemption notice.
Upon any such provisional redemption, we will make an additional payment in cash
equal to $166.67 per $1,000 principal amount of notes, less the amount of any
interest actually paid on the notes before the provisional redemption date.

     We may also redeem some or all of the notes at any time on or after June
22, 2004 at the redemption prices set forth in this prospectus, if the closing
price of our common stock has exceeded 130% of the conversion price then in
effect for at least 20 trading days within a period of 30 consecutive trading
days ending on the trading day before the date of mailing of the optional
redemption notice.

     We will not receive any proceeds from the sale by the selling
securityholders of the notes or the common stock issuable upon conversion of the
notes. Other than selling commissions and fees and stock transfer taxes, we will
pay all expenses of the registration of the notes and the common stock and
certain other expenses as set forth in the registration rights agreement.

     INVESTING IN THE NOTES AND THE COMMON STOCK ISSUABLE UPON CONVERSION OF THE
NOTES INVOLVES A HIGH DEGREE OF RISK. PLEASE CONSIDER THE "RISK FACTORS"
BEGINNING ON PAGE 5 OF THIS PROSPECTUS.

     NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES
COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

                                     SUMMARY

         The following summary is qualified in its entirety by the more detailed
information and financial statements, including the notes thereto, included or
incorporated by reference in this prospectus. For presentation purposes,
references made to any fiscal year relate to the fiscal year ending June 30 of
such year.

The Company

         We are a leading developer, manufacturer and distributor of medical
equipment for treating, diagnosing, and managing sleep disordered breathing, or
SDB. SDB includes obstructive sleep apnea, or OSA, and other related respiratory
disorders that occur during sleep. Nasal Continuous Positive Airway Pressure, or
CPAP, developed by Dr. Colin Sullivan, was the first successful noninvasive
treatment for OSA. CPAP systems deliver pressurized air, typically through a
nasal mask, to prevent collapse of the upper airway during sleep. CPAP is not a
cure, but a therapy for managing OSA, and therefore, must be used on a daily
basis as long as therapy is required.

         Since the development of nasal CPAP, we have developed a number of
innovative products for SDB, including flow generators, diagnostic products,
mask systems, headgear and other accessories. Our growth has been fueled by a
productive research and product development effort, geographic expansion and
increased awareness of SDB as a significant health concern among physicians and
patients. In February 2001, we acquired MAP Medizin-Technologie GmbH, or MAP.
MAP is a leading German designer, manufacturer and distributor of medical
devices for the diagnosis and treatment of SDB, with a particular focus on OSA.
This acquisition enhances our position in Europe, particularly in Germany, the
second largest market worldwide for OSA products.

         We employ over 950 people and sell our products in over 60 countries
through a combination of wholly owned subsidiaries and independent distributors.

The Offering


Notes offered ..............      $180,000,000 aggregate principal amount of 4%
                                  convertible subordinated notes due 2006.

Maturity ...................      June 20, 2006.

Interest ...................      4% per year on the principal amount, payable
                                  semiannually on June 20 and December 20,
                                  beginning on December 20, 2001.

Conversion rights ..........      The notes are convertible, at the option of
                                  the holder, at any time on or prior to
                                  maturity into shares of our common stock at a
                                  conversion price of $60.60 per share, which is
                                  equal to a conversion rate of 16.5017 shares
                                  per $1,000 principal amount of notes. The
                                  conversion price is subject to adjustment. See
                                  "Description of Notes -- Conversion Rights."

Ranking ....................      The notes will be unsecured and subordinated
                                  to all of our existing and future senior
                                  indebtedness (as defined) and effectively
                                  subordinated to all indebtedness and other
                                  liabilities of our subsidiaries. At August 31,
                                  2001, we had no senior indebtedness
                                  outstanding. Because the notes are
                                  subordinated, in the event of bankruptcy,
                                  liquidation, dissolution or acceleration of
                                  payment on the senior indebtedness, holders of
                                  the notes will not receive any payment until
                                  holders of the senior indebtedness have been
                                  paid in full. The indenture does not limit the
                                  incurrence by us or our subsidiaries of senior
                                  indebtedness or other obligations.

                                  We are structured as a holding company and we
                                  conduct all of our business operations through
                                  our subsidiaries. The notes are effectively
                                  subordinated to all existing and future
                                  indebtedness and other liabilities of our
                                  subsidiaries. At August 31, 2001, our
                                  subsidiaries had aggregate liabilities of
                                  approximately $42.6 million, excluding both
                                  the intercompany indebtedness and the debt
                                  related to the notes.

                                        3



Provisional redemption .....      We may redeem the notes, in whole or in part,
                                  at any time before June 20, 2004 at a
                                  redemption price equal to $1,000 per $1,000
                                  principal amount of notes to be redeemed, plus
                                  accrued and unpaid interest, if any, to the
                                  date of the provisional redemption if (i) the
                                  closing price of our common stock has exceeded
                                  150% of the conversion price then in effect
                                  for at least 20 trading days within a period
                                  of 30 consecutive trading days ending on the
                                  trading day before the date of mailing of the
                                  provisional redemption notice and (ii) the
                                  shelf registration statement covering resales
                                  of the notes and the common stock issuable
                                  upon conversion of the notes is effective and
                                  available for use and is expected to remain
                                  effective and available for use for the 30
                                  days following the provisional redemption
                                  date.

                                  Upon any provisional redemption, we will make
                                  an additional "make-whole" payment in cash
                                  with respect to the notes called for
                                  redemption in an amount equal to $166.67 per
                                  $1,000 principal amount of notes, less the
                                  amount of any interest actually paid on the
                                  notes before the provisional redemption date.
                                  We are obligated to make this additional
                                  payment on all notes called for provisional
                                  redemption, including any notes converted
                                  after the notice date and before the
                                  provisional redemption date. See "Description
                                  of Notes -- Provisional Redemption."

Optional redemption ........      We may redeem the notes, in whole or in part,
                                  on or after June 22, 2004 at the redemption
                                  prices listed in this prospectus, plus accrued
                                  and unpaid interest, if the closing price of
                                  our common stock has exceeded 130% of the
                                  conversion price then in effect for at least
                                  20 trading days within a period of 30
                                  consecutive trading days ending on the trading
                                  day before the date of mailing of the optional
                                  redemption notice. See "Description of Notes
                                  -- Optional Redemption by ResMed."

Change of control ..........      Upon a change of control, each holder of the
                                  notes may require us to repurchase some or all
                                  of its notes at a purchase price equal to 100%
                                  of the principal amount of the notes plus
                                  accrued and unpaid interest. We may, at our
                                  option, instead of paying the change of
                                  control purchase price in cash, pay it in
                                  shares of our common stock valued at 95% of
                                  the average of the closing sales prices of our
                                  common stock for the five trading days
                                  immediately preceding and including the third
                                  trading day prior to the date we are required
                                  to repurchase the notes. We cannot pay the
                                  change of control purchase price in common
                                  stock unless we satisfy the conditions
                                  described in the indenture under which the
                                  notes will be issued. See "Description of
                                  Notes-- Repurchase at Option of Holders Upon a
                                  Change of Control."

DTC eligibility ............      The notes were issued in fully registered
                                  form. The notes are represented by one or more
                                  global notes, deposited with a trustee as
                                  custodian for The Depository Trust Company and

                                  nominee. Beneficial interests in the global
                                  notes are effected only through records
                                  maintained by DTC and its participants. See
                                  "Description of Notes -- Global Notes,

                                  RISK FACTORS

         An investment in the securities offered by this prospectus involves a
high degree of risk. You should carefully consider the following factors and
other information in this prospectus before deciding to purchase the notes or
our common stock. These risks and uncertainties are not the only ones we face.
Others that we do not know about now, or that we do not now think are important,
may impair our business or the trading price of our notes and our common stock.

Our inability to compete successfully in our markets may harm our business.

         The markets for our SDB products are highly competitive and are
characterized by frequent product improvements and evolving technology. Our
ability to compete successfully depends, in part, on our ability to develop
innovative new products and to be the first to market with those products. The
development of innovative new products by our competitors or the discovery of
alternative treatments or potential cures for the conditions that our products
treat could result in our products becoming noncompetitive or obsolete.

         Additionally, some of our competitors have greater financial, research
and development, manufacturing and marketing resources than we do. The past
several years have seen a trend towards consolidation in the health care
industry and in the markets for our products. Industry consolidation could
result in greater competition if our competitors combine their resources or if
our competitors are acquired by other companies with greater resources than
ours. This competition could increase pressure on us to reduce the selling
prices of our products or could cause us to increase our spending on research
and development and sales and marketing. If we are unable to develop innovative
new products, maintain competitive pricing, and offer products that consumers
perceive to be as reliable as those of our competitors, our sales or gross
margins could decrease which would harm our business.

Our business depends on our ability to market effectively to dealers of home
health care products and sleep clinics.

         We market our products primarily to home health care dealers and to
sleep clinics that diagnose OSA and other sleep disorders. We believe that home
health care dealers and sleep clinics play a significant role in determining
which brand of CPAP product a patient will use. For example, in the United
States, when a physician at a sleep clinic prescribes the use of a CPAP product,
the patient typically purchases the product from a home health care dealer. The
physician may or may not prescribe a specific brand of CPAP product. If a
specific brand is prescribed, we believe the brand prescribed depends upon the
brand of CPAP product that is used in the sleep clinic. If a specific brand is
not prescribed, the home health care dealer may recommend a specific brand.
Occasionally, even if the physician prescribes a specific brand, a home health
care dealer may substitute a competitive CPAP product for the patient. We have
limited resources to market to the more than 2,000 U.S. sleep clinics and the
more than 4,000 home health care dealer branch locations, most of which use,
sell or recommend several brands of CPAP products. In addition, home health care
dealers have experienced price pressures as government and third-party
reimbursement have declined for home care products, and home health care dealers
are requiring price discounts and longer periods of time to pay for products
purchased from us. We cannot assure you that sleep clinic physicians will
continue to prescribe our products, or that home health care dealers or patients
will not substitute competing products when a prescription specifying our
products has been written. The success of our business depends on our ability to
market effectively to home health care dealers and sleep clinics and to ensure
that our products are properly marketed and sold by these third parties.

         We intend to expand our marketing activities to target the population
with a predisposition to SDB as well as primary care physicians and specialists.
We cannot assure you that these marketing efforts will be successful in
increasing awareness of our products.

If we are unable to support our continued growth, our business could suffer.

         We have experienced rapid and substantial growth. As we continue to
grow, the complexity of our operations increases, placing greater demands on our
management. Our ability to manage our growth effectively depends upon our
ability to implement and improve our financial and management information
systems on a timely basis and to effect other changes in our business.
Unexpected difficulties during expansion, the failure to attract and retain
qualified employees, the failure to successfully replace or upgrade our
management information systems, the failure to manage costs or our inability to
respond effectively to growth or plan for future expansion could cause our
growth to stop. If we fail to manage our growth, our business could suffer.

                                        5



If we fail to integrate our recent acquisition in Germany with our operations,
our business could suffer.

         On February 16, 2001, we acquired all of the outstanding shares of MAP
located near Munich, Germany. We are currently in the process of integrating our
operations with those of MAP. The integration requires significant efforts from
each company. We may find it difficult to integrate the operations of MAP. MAP
personnel may leave MAP because of the acquisition and MAP licensees,
distributors or suppliers may terminate their arrangements with MAP, or demand
amended terms to these arrangements. Additionally, our management may have their
attention diverted while trying to integrate the two companies. This diversion
or these difficulties in integration could have an adverse impact on us. If we
are not able to successfully integrate the operations of MAP, we may not realize
the anticipated benefits of the MAP acquisition.

We manufacture substantially all of our products outside the United States and
sell a significant portion of our products in non-U.S. markets, subjecting us to
various risks relating to international activities that could adversely affect
our overall profitability.

         Sales outside North and Latin America accounted for approximately 48%,
46%, and 43% of our net revenues in fiscal years 2001, 2000 and 1999,
respectively. As a result of the MAP acquisition, we expect that sales within
these areas will account for over 50% of our net revenues in the foreseeable
future. Our sales outside of North America and our operations in Europe,
Australia and Asia are subject to several difficulties and risks that are
separate and distinct from those we face in our domestic operations, including:

         .   fluctuations in currency exchange rates;

         .   tariffs and other trade barriers;

         .   compliance with foreign medical device manufacturing regulations;

         .   reduction in third party payor reimbursement for our products;

         .   inability to obtain import licenses;

         .   changes in trade policies and in domestic and foreign tax policies;

         .   possible changes in export or import restrictions; and

         .   the modification or introduction of other governmental policies
             with potentially adverse effects.

Fluctuations in foreign currency exchange rates could result in declines in our
reported sales and earnings.

         Since our international sales and a significant portion of our
manufacturing costs are denominated in local currencies and not in U.S. dollars,
our reported sales and earnings are subject to fluctuations in foreign exchange
rates. We had foreign currency transaction losses in recent periods and may have
further losses in the future. We expect that international sales will continue
to be a significant portion of our business and that a significant portion of
our manufacturing costs will continue to be denominated in Australian dollars.

Government and private insurance plans may not reimburse patients for our
products, which could result in reductions in sales or selling prices for our
products.

         Our ability to sell our products depends in large part on the extent to
which reimbursement for the cost of our products will be available from
government health administration authorities, private health insurers and other
organizations. These third party payors are increasingly challenging the prices
charged for medical products and services. Therefore, even if a product is
approved for marketing, we cannot assure you that reimbursement will be allowed
for such product or that the reimbursement amount will be adequate or, if
adequate, will not subsequently be reduced. For example, in some markets, such
as Spain, France and Germany, government reimbursement is currently available
for purchase or rental of our products but is subject to constraints such as
price controls or unit sales limitations. In other markets, such as Australia
and the United Kingdom, there is currently limited or no reimbursement for
devices that treat sleep disordered breathing related respiratory conditions.
Additionally, future legislation or regulation concerning the health care
industry or third party or governmental coverage and reimbursement,
particularly, legislation or regulation limiting consumers' reimbursement rights
may harm our business. As we continue to develop new products, those products
will generally not qualify for reimbursement, if at all, until they are approved
for marketing.

                                        6



         In the United States, we sell our products primarily to home health
care dealers and to sleep clinics. We do not file claims and bill governmental
programs and other third party payors directly for reimbursement for our
products. However, we are still subject to laws and regulations relating to
governmental reimbursement programs, particularly Medicaid and Medicare.

         In particular, the federal Anti-Kickback Law prohibits persons from
knowingly and willfully soliciting, receiving, offering or providing
remuneration, directly or indirectly, to induce either the referral of an
individual, or the furnishing, recommending or arranging for a good or service,
for which payment may be made under a federal healthcare program such as the
Medicare and Medicaid programs. The government has interpreted this law broadly
to apply to the marketing and sales activities of manufacturers and distributors
like us. Many states have adopted laws similar to the federal Anti-Kickback Law.
We are also subject to other federal and state fraud laws applicable to payment
from any third party payor. These laws prohibit persons from knowingly and
willfully filing false claims or executing a scheme to defraud any healthcare
benefit program, including private third party payors. These laws may apply to
manufacturers and distributors who provide information on coverage, coding, and
reimbursement of their products to persons who do bill third party payors. Any
violation of these laws and regulations could result in civil and criminal
penalties, including fines.

Complying with FDA and other regulations is an expensive and time consuming
process, and any failure to comply could result in substantial penalties.

         We are subject to various federal, state, local and international
regulations regarding the testing, manufacture, distribution, marketing,
promotion, record keeping and reporting of our products. In particular, our
failure to comply with FDA regulations could result in, among other things,
recalls of our products, substantial fines and/or criminal charges against us
and our employees.

Product sales, introductions or modifications may be delayed or canceled as a
result of the FDA or similar foreign regulations, which could cause our sales to
decline.

         Before we can market or sell a new medical device in the United States,
we must obtain FDA clearance, which can be a lengthy and time consuming process.
We generally receive clearance from the FDA to market our products in the United
States under Section 510(k) of the Federal Food, Drug, and Cosmetic Act or our
products are exempt from the 510(k) clearance process. We have modified some of
our 510(k) approved products without submitting new 510(k) notices, which we do
not believe were required. However, if the FDA disagrees with us and requires us
to submit new 510(k) notifications for modifications to our existing products,
we may be required to stop marketing the products while the FDA reviews the
510(k) notification. Any new product introduction or existing product
modification could be subjected to a lengthier, more rigorous FDA examination
process. For example, in certain cases we may need to conduct clinical trials of
a new product prior to submitting a 510(k) notice. Additionally, we may be
required to obtain premarket approvals for our products. The requirements of
these more rigorous processes could delay product introductions and increase the
costs associated with FDA compliance. Marketing and sale of our products outside
the United States are also subject to regulatory clearances and approvals, and
if we fail to obtain these regulatory approvals, our sales could suffer. We
cannot assure you that any new products we develop will receive required
regulatory approvals from U.S. or foreign regulatory agencies.

Off label marketing of our products could result in substantial penalties.

         Clearance under Section 510(k) only permits us to market our products
for the uses indicated on the labeling cleared by the FDA. We may request
additional label indications for our current products, and the FDA may deny
those requests outright, require additional expensive clinical data to support
any additional indications or impose limitations on the intended use of any
cleared products as a condition of clearance. If the FDA determines that we have
marketed our products for off label use, we could be subject to fines,
injunctions or other penalties.

Disruptions in the supply of components from our single source suppliers could
result in a significant reduction in sales and profitability.

         We purchase uniquely configured components for our devices from
single-source suppliers. We cannot assure you that a replacement supplier would
be able to configure its components for our devices on a timely basis or, in the
alternative, that we would be able to reconfigure our devices to integrate the
replacement part. A reduction or stoppage in supply while a replacement supplier
reconfigures its components, or while we reconfigure our components for the
replacement part, would limit our ability to manufacture our devices, which
could result in a significant reduction in sales and profitability. We cannot
assure you that our inventories would be adequate to meet our production needs
during any prolonged interruption of supply.

Our intellectual property may not protect our products, and our products may
infringe on the intellectual property rights of third parties.

         We rely on a combination of patents, trade secrets and non-disclosure
agreements to protect our intellectual property. Our success depends, in part,
on our ability to obtain and maintain United States and foreign patent
protection for our products, their uses and our processes to preserve our trade
secrets and to operate without infringing on the proprietary rights of third
parties. We have a number of pending patent applications, and we do not know
whether any patents will issue from any of these applications. We do not know
whether any of the claims in our issued patents or pending applications will
provide us with any significant protection against competitive products or
otherwise be commercially valuable. Legal standards regarding the validity of
patents and the proper scope of their claims are still evolving, and there is no
consistent law or policy regarding the valid breadth of claims. Additionally,
there may be third party patents, patent applications and other intellectual
property relevant to our products and technology which are not known to us and
that block or compete with our products.

         We face the risks that:

         .   third parties will infringe our intellectual property rights;

         .   our non-disclosure agreements will be breached;

         .   we will not have adequate remedies for infringement;

         .   our trade secrets will become known to or independently developed
             by our competitors; or

         .   any third parties will be issued patents that may prevent the sale
             of our products or require us to license and pay fees or royalties
             in order for us to be able to market some of our products.

         We are currently engaged in litigation relating to the enforcement and
defense of five of our patents. Additional litigation may be necessary to
enforce patents issued to us, to protect our proprietary rights, or to defend
third party claims that we have infringed upon proprietary rights of others. The
defense and prosecution of patent claims, including these pending claims, as
well as participation in other inter-party proceedings, can be expensive and
time consuming, even in those instances in which the outcome is favorable to us.
If the outcome of any litigation or proceeding brought against us were adverse,
we could be subject to significant liabilities to third parties, could be
required to obtain licenses from third parties or could be required to cease
sales of the affected products. Additionally, the laws regarding the
enforceability of patents vary from country to country, and we cannot assure you
that any patent issues we face will be uniformly resolved, or that local laws
will provide us with consistent rights and benefits.

We are subject to product liability claims that may exceed the scope and amount
of our insurance coverage, which would expose us to liability for uninsured
claims.

         We are subject to potential product liability claims as a result of the
design, manufacture and marketing of medical devices. Any product liability
claim brought against us, with or without merit, could result in the increase of
our product liability insurance rates. In addition, we would have to pay any
amount awarded by a court in excess of our policy limits. Our insurance policies
have various exclusions, and thus we may be subject to a product liability claim
for which we have no insurance coverage, in which case, we may have to pay the
entire amount of any award. We cannot assure you that our insurance coverage
will be adequate or that all claims brought against us will be covered by our
insurance. Insurance varies in cost and can be difficult to obtain, and we
cannot assure you that we will be able to obtain insurance in the future on
terms acceptable to us or at all. A successful product liability claim brought
against us in excess of our insurance coverage, if any, may require us to pay
substantial amounts, which could harm our business.

Our business could suffer if we lose the services of key members of our
management.

         We are dependent upon the continued services of key members of our
senior management and a limited number of key employees and consultants. The
loss of the services of any one of these individuals could significantly disrupt
our operations. Additionally, our future success will depend, among other
factors, on our ability to continue to hire and retain the necessary qualified
scientific, technical and managerial personnel. We compete for such personnel
with numerous other companies, academic institutions and organizations.

Our quarterly operating results are subject to fluctuation for a variety of
reasons.

     Our operating results have, from time to time, fluctuated on a quarterly
basis and may be subject to similar fluctuations in the future. These
fluctuations may result from a number of factors, including:

     .    the introduction of new products by us or our competitors;

     .    the geographic mix of product sales;

     .    the success of our marketing efforts in new regions;

     .    changes in third party reimbursement;

     .    timing of regulatory clearances and approvals;

     .    timing of orders by distributors;

     .    expenditures incurred for research and development;

     .    competitive pricing in different regions;

     .    seasonality;

     .    the cost and effect of promotional and marketing programs; and

     .    the effect of foreign currency transaction gains or losses.

We are subject to an ongoing tax audit, the results of which may require
significant tax adjustments.

     We are subject to an ongoing audit of our tax returns for the years 1995
through 1998, which began in February 1998. The IRS may disagree with our tax
positions on such returns, and if challenged by the IRS, our tax positions may
not be sustained by the courts. As a result of these audits, we may be required
to make certain tax adjustments and pay additional taxes and fines that may be
significant and have a negative impact on our result of operations.

If a natural or man made disaster strikes our manufacturing facilities, we will
be unable to manufacture our products for a substantial amount of time and our
sales will decline.

     We manufacture a significant portion of our products in our facilities in
Australia. These facilities and the manufacturing equipment we use to produce
our products would be costly to replace and could require substantial lead time
to repair or replace. The facilities may be affected by natural or man made
disasters and in the event it was affected by a disaster, we would be forced to
rely on third party manufacturers. Although we believe we possess adequate
insurance for damage to our property and the disruption of our business from
casualties, such insurance may not be sufficient to cover all of our potential
losses and may not continue to be available to us on acceptable terms, or at
all.

Delaware law, provisions in our charter and our shareholder rights plan could
make the acquisition of our company by another company more difficult.

     Provisions of our certificate of incorporation may have the effect of
delaying or preventing changes in control or management which might be
beneficial to us or our securityholders. In particular, our board of directors
is divided into three classes, serving for staggered three year terms. Because
of this classification it will require at least two annual meetings to elect
directors constituting a majority of our board of directors.

     Additionally, our board of directors has the authority to issue up to
2,000,000 shares of preferred stock and to determine the price, rights,
preferences, privileges and restrictions, including voting rights, of those
shares without further vote or action by the stockholders. Under our
stockholders rights plan, we have also issued purchase rights to the holders of
our common stock that entitle those holders to purchase our Series A Junior
Participating Preferred Stock at a discount, under certain circumstances. The
rights of the holders of our common stock will be subject to, and may be
adversely affected by, the rights of the holders of any preferred stock that may
be issued in the future. The issuance of preferred stock may have the effect of
delaying, deferring or preventing a change in control, may discourage bids for
our common stock at a premium over the market price of our common stock and may
adversely affect the market price of our common stock and the voting and other
rights of the holders of our common stock.

You may not be able to enforce the judgments of U.S. courts against some of our
assets or officers and directors.

     A substantial portion of our assets are located outside the United States.
Additionally, two of our six directors and three of our eight officers reside
outside the United States, along with all or a substantial portion of the assets
of these persons. As a result, it may not be possible for investors to enforce
judgments of U.S. courts relating to any liabilities under this prospectus or
the U.S. securities laws against our assets, those persons or their assets. In
addition, we have been advised by our Australian counsel that some doubt exists
as the ability of investors to pursue claims based on the contents of this
prospectus or the U.S. securities laws against these assets or these persons in
Australian courts.

The notes are subordinated to any existing and future senior debt.

     The notes are contractually subordinated in right of payment to our
existing and future senior debt. As of August 31, 2001, we had no senior debt.
The indenture does not limit the creation of additional senior debt (or any
other indebtedness). Any significant additional senior debt incurred may harm
our ability to service our debt, including the notes. Because of the
subordination provisions, in the event of bankruptcy, insolvency, liquidation or
dissolution, funds which we would otherwise use to pay the holders of the notes
will be used to pay the holders of senior debt to the extent necessary to pay
the senior debt in full. As a result of these payments, our general creditors
may recover less, ratably, than the holders of our senior debt and such general
creditors may recover more, ratably, than the holders of our notes or our other
subordinated indebtedness. In addition, the holders of our senior debt may,
under certain circumstances, restrict or prohibit us from making payments on the
notes.

We are a holding company and we may not be able to meet our debt service
obligations under the notes.

     ResMed Inc. is a holding company and we conduct all of our operations
through our subsidiaries. Consequently ResMed Inc., the obligor under the notes,
does not have any income from operations and does not expect to generate income
from operations. As a result, our ability to meet our debt service obligations,
including our obligations under the notes, substantially depends upon our
subsidiaries' cash flow and payment of funds to us by our subsidiaries as
dividends, loans, advances or other payments. Our subsidiaries' payment of
dividends or making of loans, advances or other payments may be subject to
regulatory or contractual restrictions or other limitations.

Because the notes are effectively subordinated to the debt and other liabilities
of our subsidiaries, you may not receive a full payment on your notes.

     Because ResMed Inc. is a holding company, the notes will be effectively
subordinated to all existing and future indebtedness and other liabilities of
our subsidiaries. At August 31, 2001, our subsidiaries had aggregate liabilities
of approximately $42.6 million, excluding both the intercompany indebtedness and
the debt related to the notes. Any right we may have to receive assets of our
subsidiaries upon their liquidation or reorganization, and your resulting rights
to participate in those assets, would be effectively subordinated to the claims
of our subsidiaries' creditors. In addition, all of our intellectual property is
held by or licensed through our subsidiaries and all of our real property is
held by our subsidiaries.

Our stock price has been and may continue to be volatile.

     The trading price of our common stock has been and may continue to be
subject to large fluctuations. Our stock price may increase or decrease in
response to a number of events and factors, including.

     .    quarterly variations in operating results;

     .    changes in financial estimates and recommendations by securities
          analysts;

     .    changes in government regulation;

     .    developments with respect to patents, proprietary rights or
          litigation;

     .    the operating and stock price performance of other companies that
          investors may deem comparable to our company;

     .    news reports relating to trends in our industry and the markets in
          which we operate;

     .    acquisitions and financings; and

     .    sales of blocks of stock by insiders.

                                       10



     The majority of this volatility, however, is attributable to the current
state of the stock market, in which wide price swings are common. This
volatility may adversely affect the price of our common stock, regardless of our
operating performance.

Our ability to repurchase notes, if required, may be limited.

     In certain circumstances, including a change of control, the holders of the
notes may require us to repurchase some or all of the holder's notes. We cannot
assure you that we will have sufficient financial resources at such time or
would be able to arrange financing to pay the repurchase price of the notes. Our
ability to repurchase the notes in such event may be limited by law, the
indenture, or the terms of other agreements relating to our senior debt. We may
be required to refinance our senior debt in order to make such payments.

An active trading market for the notes may not develop.

     The notes are a new issue of securities for which there is currently no
trading market. Although the notes that were sold to qualified institutional
buyers pursuant to Rule 144A are eligible for trading in the PORTAL market, the
notes resold pursuant to this prospectus will no longer trade on the PORTAL
market. As a result, there may be a limited market for the notes. We do not
intend to list the notes on any national securities exchange or on the Nasdaq
National Market. Accordingly, we cannot predict whether an active trading market
for the notes will develop or be sustained. If an active market for the notes
fails to develop or be sustained, the trading price of the notes could fall. If
an active trading market were to develop, the notes could trade at prices that
may be lower than the initial offering price of the notes.

Any rating of the notes may cause their trading price to fall.

     In the future, one or more rating agencies may rate the notes. If the
rating agencies rate the notes, they may assign a lower rating than expected by
investors. Rating agencies may also lower ratings on the notes in the future. If
the rating agencies assign a lower than expected rating or reduce their ratings
in the future, the trading price of the notes could decline.

                                 DIVIDEND POLICY

     We have not paid any cash dividends on our common stock since prior to the
initial public offering of our common stock and we do not currently intend to
pay cash dividends in the foreseeable future. Management anticipates that all of
our earnings and other cash resources, if any, will be retained for the
operation and expansion of our business and for general corporate purposes.

                              DESCRIPTION OF NOTES

     The notes are issued under an indenture between us and American Stock
Transfer & Trust Company, as trustee. The terms of the notes include those
provided in the indenture and the registration rights agreement, which we
entered into with the initial purchasers. A copy of the form of indenture and
the registration rights agreement are available upon request. This section
summarizes certain provisions of the notes, the indenture and the registration
rights agreement. This summary is not complete. We urge you to read the
indenture because it defines your rights as a holder of the notes. Terms not
defined in this description have the meanings given to them in the indenture.
Whenever particular portions of the indenture or the registration rights
agreement are referred to, such provisions are incorporated herein by reference.
In this section, the words "we," "us," "our" or "ResMed" do not include any
current or future subsidiary of ResMed Inc.

General

     The notes represent general unsecured obligations of ResMed Inc. and are
subordinated in right of payment to certain of our other obligations as
described under "-- Subordination of Notes" below and convertible into our
common stock as described under "-- Conversion Rights" below. The notes will be
limited to $180,000,000 aggregate principal amount and will mature on June 20,
2006.

     The notes bear interest at the rate of 4% per year from June 20, 2001, or
from the most recent date to which interest had been paid or provided for,
subject to adjustment, upon the occurrence of a Reset Transaction. See "--
Interest Rate Adjustments" below. Interest will be payable semi-annually on June
20 and December 20, of each year, commencing December 20, 2001, to holders of
record at the close of business on the preceding June 5 and December 5,
respectively. Interest will be computed on the basis of a 360-day year comprised
of twelve 30-day months. In the event of the maturity, conversion, purchase by
us at the option of the holder or redemption of a note, interest will cease to
accrue on the note under the terms of and subject to the conditions of the
indenture.

     Principal will be payable, and the notes may be presented for conversion,
registration of transfer and exchange, without service charge, at our office or
agency in New York City, which shall initially be the office or agency of the
trustee in New York, New York. See "-- Form, Denomination and Registration."

     The indenture does not contain any financial covenants or any restrictions
on the payment of dividends, the repurchase of our securities or the incurrence
of Senior Indebtedness (as defined below under "-- Subordination of Notes") or
any other indebtedness. The indenture also does not contain any covenants or
other provisions to afford protection to holders of the notes in the event of a
highly leveraged transaction or a change in control of ResMed except to the
extent described under "-- Interest Rate Adjustments" and under "-- Change of
Control Permits Purchase of Notes at the Option of the Holder" below.

Interest Rate Adjustments

     If a Reset Transaction occurs, the interest rate will be adjusted to equal
the Adjusted Interest Rate from the effective date of such Reset Transaction to,
but not including, the effective date of any succeeding Reset Transaction.

     A "Reset Transaction" means:

     .    a merger, consolidation or statutory share exchange to which the
          entity that is the issuer of the common stock into which the notes are
          then convertible into is a party;

     .    a sale of all or substantially all the assets of that entity;

     .    a recapitalization of that common stock; or

     .    a distribution described in clause (4) of the fourth paragraph under
          "--Conversion Rights" below,

after the effective date of which transaction or distribution the notes would be
convertible into:

     .    shares of an entity the common stock of which had a dividend yield for
          the four fiscal quarters of such entity immediately preceding the
          public announcement of the transaction or distribution that was more
          than 2.5% higher than the dividend yield on our common stock (or other
          common stock then issuable upon conversion of the notes) for the four
          fiscal quarters preceding the public announcement of the transaction
          or distribution; or

                                       14



     .    shares of an entity that announces a dividend policy prior to the
          effective date of the transaction or distribution which policy, if
          implemented, would result in a dividend yield on that entity's common
          stock for the next four fiscal quarters that would result in such a
          2.5% increase.

     The "Adjusted Interest Rate" with respect to any Reset Transaction will be
the rate per year that is the arithmetic average of the rates quoted by two
dealers engaged in the trading of convertible securities selected by us or our
successor as the rate at which interest should accrue so that the fair market
value, expressed in dollars, of a note immediately after the later of:

     .    the public announcement of the Reset Transaction; or

     .    the public announcement of a change in dividend policy in connection
          with the Reset Transaction,

will equal the average Trading Price of a note for the 20 trading days preceding
the date of public announcement of the Reset Transaction. However, the Adjusted
Interest Rate will not be less than 4% per year.

     For purposes of the definition of Reset Transaction, the dividend yield on
any security for any period means the dividends paid or proposed to be paid
pursuant to an announced dividend policy on the security for that period divided
by, if with respect to dividends paid on that security, the average Closing
Price (as defined in the indenture) of the security during that period and, if
with respect to dividends proposed to be paid on the security, the Closing Price
of such security on the effective date of the related Reset Transaction.

     The "Trading Price" of a security on any date of determination means:

     .    the closing sale price (or, if no closing sale price is reported, the
          last reported sale price) of a security (regular way) on the New York
          Stock Exchange ("NYSE") on that date;

     .    if that security is not listed on the NYSE on that date, the closing
          sale price as reported in the composite transactions for the principal
          U.S. securities exchange on which that security is listed;

     .    if that security is not so listed on a U.S. national or regional
          securities exchange, the closing sale price as reported by the Nasdaq
          National Market;

     .    if that security is not so reported, the last price quoted by
          Interactive Data Corporation for that security or, if Interactive Data
          Corporation is not quoting such price, a similar quotation service
          selected by us;

     .    if that security is not so quoted, the average of the mid-point of the
          last bid and ask prices for that security from at least two dealers
          recognized as market-makers for that security; or

     .    if that security is not so quoted, the average of the last bid and ask
          prices for that security from a dealer engaged in the trading of
          convertible securities.

Conversion Rights

     The holders of the notes may, at any time on or prior to the close of
business on the final maturity date of the notes, convert any outstanding notes
(or portions thereof) into our common stock, initially at the conversion price
of $60.60 per share, subject to adjustment as described below. Holders may
convert the notes only in denominations of $1,000 and whole multiples of $1,000.
Except as described below, no payment or other adjustment will be made on
conversion of any notes for interest accrued thereon or for dividends on any
common stock.

     If notes are converted after a record date for an interest payment but
prior to the next interest payment date, those notes must be accompanied by
funds equal to the interest payable to the record holder on the next interest
payment date on the principal amount so converted. No payment will be required
from a holder if we exercise our right to redeem such notes. We are not required
to issue fractional shares of common stock upon conversion of notes and instead
will pay a cash adjustment based upon the market price of our common stock on
the last business day before the date of conversion. In the case of notes called
for redemption, conversion rights will expire at the close of business on the
business day preceding the day fixed for redemption, unless we default in the
payment of the redemption price.

     A holder may exercise the right of conversion by delivering the note to be
converted to the specified office of a conversion agent, with a completed notice
of conversion, together with any funds that may be required as described in the
preceding paragraph. The conversion date will be the date on which the notes,
the notice of conversion and any required funds have been so delivered. A holder
delivering a note for conversion will not be required to pay any taxes or duties
relating to the issuance or delivery of the

                                       15



common stock for such conversion, but will be required to pay any tax or duty
which may be payable relating to any transfer involved in the issuance or
delivery of the common stock in a name other than the holder of the note.
Certificates representing shares of common stock will be issued or delivered
only after all applicable taxes and duties, if any, payable by the holder have
been paid. If any note is converted within two years after its original
issuance, the common stock issuable upon conversion will not be issued or
delivered in a name other than that of the holder of the note unless the
applicable restrictions on transfer have been satisfied. See "Notice to
Investors."

         The initial conversion price will be adjusted for certain events,
including:

         1. the issuance of our common stock as a dividend or distribution
on our common stock;

         2. certain subdivisions and combinations of our common stock;

         3. the issuance to all holders of our common stock of certain rights or
warrants to purchase our common stock (or securities convertible into our common
stock) at less than (or having a conversion price per share less than) the
current market price of our common stock;

         4. the dividend or other distribution to all holders of our common
stock of shares of our capital stock (other than common stock) or evidences of
our indebtedness or our assets (including securities, but excluding those rights
and warrants referred to in clause (3) above and dividends and distributions in
connection with a reclassification, change, consolidation, merger, combination,
sale or conveyance resulting in a change in the conversion consideration
pursuant to the second succeeding paragraph below and dividends or distributions
paid exclusively in cash);

         5. dividends or other distributions consisting exclusively of cash to
all holders of our common stock (excluding any cash that is distributed upon a
reclassification or change of our common stock, merger, consolidation, statutory
share exchange, combination, sale or conveyance as described in the second
succeeding paragraph hereof or as part of a distribution referred to in clause
(4) above) to the extent that such distributions, combined together with (A) all
other such all-cash distributions made within the preceding 12 months for which
no adjustment has been made plus (B) any cash and the fair market value of other
consideration paid for any tender or exchange offers by us or any of our
subsidiaries for our common stock concluded within the preceding 12 months for
which no adjustment has been made, exceeds 10% of our market capitalization on
the record date for such distribution; market capitalization is the product of
the then current market price of our common stock and the number of shares of
our common stock then outstanding; and

         6. the purchase of our common stock pursuant to a tender offer or
exchange offer made by us or any of our subsidiaries which involves an aggregate
consideration that, together with (A) any cash and the fair market value of any
other consideration paid in any other tender offer or exchange offer by us or
any of our subsidiaries for our common stock expiring within the 12 months
preceding such tender offer or exchange offer for which no adjustment has been
made plus (B) the aggregate amount of any all-cash distributions referred to in
clause (5) above to all holders of our common stock within 12 months preceding
the expiration of that tender offer or exchange offer for which no adjustment
have been made, exceeds 10% of our market capitalization on the expiration of
such tender offer or exchange offer.

         In the event that we pay a dividend or make a distribution on shares of
our common stock consisting of capital stock of, or similar equity interests in,
a subsidiary or other business unit of ours, the conversion rate will be
adjusted based on the market value of the securities so distributed relative to
the market value of our common stock, in each case based on the average closing
prices of those securities for the 10 trading days commencing on and including
the fifth trading day after the date on which "ex-dividend trading" commences
for such dividend or distribution on the principal United States securities
exchange or market on which the securities are then listed or quoted.

         No adjustment in the conversion price will be required unless such
adjustment would require a change of at least 1% in the conversion price then in
effect at such time. Any adjustment that would otherwise be required to be made
shall be carried forward and taken into account in any subsequent adjustment.
Except as stated above, the conversion price will not be adjusted for the
issuance of common stock or any securities convertible into or exchangeable for
our common stock or carrying the right to purchase any of the foregoing.

         In the case of:

         .    any reclassification or change of our common stock (other than
              changes resulting from a subdivision or combination);

                                       16



         .    a consolidation, merger or combination involving us;

         .    a sale or conveyance to another corporation of all or
              substantially all of our property and assets; or

         .    any statutory share exchange,

in each case as a result of which holders of our common stock are entitled to
receive stock, other securities, other property or assets (including cash or any
combination thereof) with respect to or in exchange for our common stock, the
holders of the notes then outstanding will be entitled thereafter to convert
such notes into the kind and amount of shares of stock, other securities or
other property or assets (including cash or any combination thereof) which they
would have owned or been entitled to receive upon such reclassification or
change of our common stock, consolidation, merger, combination, sale, conveyance
or statutory share exchange had such notes been converted into our common stock
immediately prior to such reclassification, change, consolidation, merger,
combination, sale, conveyance or statutory share exchange. We may not become a
party to any such transaction unless its terms are consistent with the
foregoing.

         If a taxable distribution to holders of our common stock or transaction
occurs which results in any adjustment of the conversion price, the holders of
notes may, in certain circumstances, be deemed to have received a distribution
subject to United States income tax as a dividend. In certain other
circumstances, the absence of such an adjustment may result in a taxable
dividend to the holders of common stock. See "United States Federal Income Tax
Considerations."

         We may from time to time, to the extent permitted by law, reduce the
conversion price of the notes by any amount for any period of at least 20 days.
In that case, we will give at least 15 days' notice of such reduction. We may
make such reductions in the conversion price, in addition to those set forth
above, as our board of directors deems advisable to avoid or diminish any income
tax to holders of our common stock resulting from any dividend or distribution
of stock (or rights to acquire stock) or from any event treated as such for
income tax purposes. See "United States Federal Income Tax Considerations."

Provisional Redemption

         We may redeem the notes, in whole or in part, at any time prior to June
20, 2004, at a redemption price equal to $1,000 per $1,000 principal amount of
notes to be redeemed plus accrued and unpaid interest, if any, to, but
excluding, the provisional redemption date if:

         .     the closing price of our common stock has exceeded 150% of the
               conversion price then in effect for at least 20 trading days
               within a period of 30 consecutive trading days ending on the
               trading day prior to the date of mailing of the provisional
               redemption notice (which date shall be at least 20 but not more
               than 60 days prior to the provisional redemption date); and

         .     the shelf registration statement covering resales of the notes
               and the common stock issuable upon conversion of the notes is
               effective and available for use and is expected to remain
               effective for the 30 days following the provisional redemption
               date.

         Upon any provisional redemption, we will make an additional
"make-whole" payment in cash with respect to the notes called for redemption to
holders on the notice date in an amount equal to $166.67 per $1,000 principal
amount of notes, less the amount of any interest actually paid on the notes
prior to the provisional redemption date.

         WE WILL BE OBLIGATED TO MAKE THIS ADDITIONAL PAYMENT ON ALL NOTES
CALLED FOR PROVISIONAL REDEMPTION, INCLUDING ANY NOTES CONVERTED AFTER THE
NOTICE DATE AND BEFORE THE PROVISIONAL REDEMPTION DATE.

Optional Redemption by ResMed

         There is no sinking fund for the notes. On and after June 22, 2004, we
will be entitled to redeem some or all of the notes on at least 30 but not more
than 60 days' notice, at the redemption prices set out below, together with
accrued and unpaid interest to, but excluding, the date fixed for redemption, if
the closing price of our common stock has exceeded 130% of the conversion price
then in effect for at least 20 trading days within a period of 30 consecutive
trading days ending on the trading day prior to the date of mailing of the
optional redemption notice. However, if a redemption date is an interest payment
date, the semi-annual payment of interest becoming due on such date shall be
payable to the holder of record as of the relevant record date and the
redemption price shall not include such interest payment.

                                       17


         The table below shows redemption prices of a note per $1,000 principal
amount if redeemed during the periods described below.

                             Period                            Redemption Price
                             ------                            ----------------

             June 22, 2004 through June 19, 2005 ...............  101.6%
             Thereafter ........................................  100.8%

         If we do not redeem all of the notes, the trustee will select the notes
to be redeemed in principal amounts of $1,000 or whole multiples of $1,000 by
lot, on a pro rata basis or in accordance with any other method the trustee
considers fair and appropriate. If any notes are to be redeemed in part only, a
new note or notes in principal amount equal to the unredeemed principal portion
thereof will be issued. If a portion of a holder's notes is selected for partial
redemption and the holder converts a portion of its notes, the converted portion
will be deemed to be taken from the portion selected for redemption.

Repurchase at Option of Holders Upon a Change of Control

         If a change of control (as defined below) occurs, each holder of notes
will have the right to require us to repurchase all of such holder's notes not
previously called for redemption, or any portion of those notes that is equal to
$1,000 or a whole multiple of $1,000, on the date that is 45 days after the date
of we give notice at a repurchase price equal to 100% of the principal amount of
the notes to be repurchased, together with interest accrued and unpaid to, but
excluding, the repurchase date; provided that, if such repurchase date is an
interest payment date, then the interest payable on such date shall be paid to
the holder of record of the notes on the relevant record date.

         Instead of paying the repurchase price in cash, we may pay the
repurchase price in common stock if we so elect in the notice referred to below.
The number of shares of common stock a holder will receive will equal the
repurchase price divided by 95% of the average of the closing sales prices of
our common stock for the five trading days immediately preceding and including
the third trading day prior to the repurchase date. However, we may not pay in
common stock unless we satisfy certain conditions prior to the repurchase date
as provided in the indenture.

         Within 30 days after the occurrence of a change of control, we are
required to give notice to all holders of record of notes, as provided in the
indenture, of the occurrence of the change of control and of their resulting
repurchase right. We must also deliver a copy of our notice to the trustee. In
order to exercise the repurchase right, a holder of notes must deliver, on or
before the 30th day after the date of our notice of the change of control,
written notice to the trustee of the holder's exercise of its repurchase right,
together with the notes with respect to which the right is being exercised.

         Under the indenture, a "change of control" of ResMed will be deemed to
have occurred at such time after the original issuance of the notes when the
following has occurred:

         .     the acquisition by any person, including any syndicate or group
               deemed to be a "person" under Section 13(d)(3) of the Securities
               Exchange Act of 1934, as amended (the "Exchange Act"), of
               beneficial ownership, directly or indirectly, through a purchase,
               merger or other acquisition transaction or series of transactions
               of shares of our capital stock entitling that person to exercise
               50% or more of the total voting power of all shares of our
               capital stock entitled to vote generally in elections of
               directors, other than any acquisition by us, any of our
               subsidiaries or any of our employee benefit plans;

         .     our consolidation or merger with or into any other person, any
               merger of another person into us, or any conveyance, transfer,
               sale, lease or other disposition of all or substantially all of
               our properties and assets to another person, other than:

         1. any transaction (A) that does not result in any reclassification,
conversion, exchange or cancellation of outstanding shares of our capital stock
and (B) pursuant to which holders of our capital stock immediately prior to the
transaction are entitled to exercise, directly or indirectly, 50% or more of the
total voting power of all shares of our capital stock entitled to vote generally
in the election of directors of the continuing or surviving person immediately
after the transaction; or

         2. any merger solely for the purpose of changing our jurisdiction of
incorporation and resulting in a reclassification, conversion or exchange of
outstanding shares of common stock solely into shares of common stock of the
surviving entity;

         .     during any consecutive two-year period, individuals who at the
               beginning of that two-year period constituted our board of
               directors (together with any new directors whose election to our
               board of directors, or whose nomination for election

                                       18



               by our stockholders, was approved by a vote of a majority of the
               directors then still in office who were either directors at the
               beginning of such period or whose election or nomination for
               election was previously so approved) cease for any reason to
               constitute a majority of our board of directors then in office;
               or

         .     we are liquidated or dissolved or our stockholders pass a
               resolution approving a plan of liquidation or dissolution.

         The beneficial owner shall be determined in accordance with Rule 13d-3
promulgated by the Commission under the Exchange Act. The term "person" includes
any syndicate or group which would be deemed to be a "person" under Section
13(d)(3) of the Exchange Act.

         Rule 13e-4 under the Exchange Act, as amended, requires the
dissemination of information to security holders if an issuer tender offer
occurs and may apply if the repurchase option becomes available to holders of
the notes. We will comply with this rule to the extent applicable at that time.

         We may, to the extent permitted by applicable law, at any time purchase
the notes in the open market or by tender at any price or by private agreement.
Any note so purchased by us may, to the extent permitted by applicable law, be
reissued or resold or may be surrendered to the trustee for cancellation. Any
notes surrendered to the trustee may not be reissued or resold and will be
canceled promptly.

         The foregoing provisions would not necessarily protect holders of the
notes if highly leveraged or other transactions involving us occur that may
adversely affect holders.

         Our ability to repurchase notes upon the occurrence of a change of
control is subject to important limitations. The occurrence of a change in
control could cause an event of default under or be prohibited or limited by,
the terms of existing or future Senior Indebtedness. As a result, any repurchase
of the notes would, absent a waiver, be prohibited under the subordination
provisions of the indenture until the Senior Indebtedness is paid in full.
Further, we cannot assure you that we would have the financial resources, or
would be able to arrange financing, to pay the repurchase price for all the
notes that might be delivered by holders of notes seeking to exercise the
repurchase right. Any failure by us to repurchase the notes when required
following a change of control would result in an event of default under the
indenture, whether or not such repurchase is permitted by the subordination
provisions of the indenture. Any such default may, in turn, cause a default
under existing or future Senior Indebtedness. See "--Subordination of Notes"
below.

Subordination of Notes

         The payment of principal of, premium, if any, and interest on the notes
is subordinated in right of payment, as set forth in the indenture, to the prior
payment in full in cash or cash equivalents of all Senior Indebtedness whether
outstanding on the date of the indenture or thereafter incurred. The notes also
are effectively subordinated to all indebtedness and other liabilities,
including trade payables and lease obligations, if any, of our subsidiaries.

         In the event of any insolvency or bankruptcy case or proceeding, or any
receivership, liquidation, reorganization or other similar case or proceeding in
connection therewith, relating to ResMed or to its assets, or any liquidation,
dissolution or other winding-up of ResMed, whether voluntary or involuntary, or
any assignment for the benefit of creditors or other marshaling of assets or
liabilities of ResMed (except in connection with the consolidation or merger of
ResMed or its liquidation or dissolution following the conveyance, transfer or
lease of its properties and assets substantially as an entirely upon the terms
and conditions described under "-- Consolidation, Mergers and Sales of Assets"
below), the holders of Senior Indebtedness will be entitled to receive payment
in full in cash or cash equivalents of all Senior Indebtedness, or provision
shall be made for such payment in full, before the holders of notes will be
entitled to receive any payment or distribution of any kind or character (other
than any payment or distribution in the form of equity securities or
subordinated securities of ResMed or any successor obligor that, in the case of
any such subordinated securities, are subordinated in right of payment to all
Senior Indebtedness that may at the time be outstanding to at least the same
extent as the notes are so subordinated (such equity securities or subordinated
securities hereinafter being "Permitted Junior Securities")) on account of
principal of, or premium, if any, or interest on the notes; and any payment or
distribution of assets of ResMed of any kind or character, whether in cash,
property or securities (other than a payment or distribution in the form of
Permitted Junior Securities), by set-off or otherwise, to which the holders of
the notes or the trustee would be entitled but for the provisions of the
indenture relating to subordination shall be paid by the liquidating trustee or
agent or other person making such payment or distribution directly to the
holders of Senior Indebtedness or their representatives ratably according to the
aggregate amounts remaining unpaid on account

         of the Senior Indebtedness to the extent necessary to make payment in
full of all Senior Indebtedness remaining unpaid, after giving effect to any
current payment or distribution to the holders of such Senior Indebtedness.

                                       19



         No payment or distribution of any assets of ResMed of any kind or
character, whether in cash, property or securities (other than Permitted Junior
Securities), may be made by or on behalf of ResMed on account of principal of,
premium, if any, or interest on the notes or on account of the purchase,
redemption or other acquisition of notes upon the occurrence of any default in
payment (whether at scheduled maturity, upon scheduled installment, by
acceleration or otherwise) of principal of, premium, if any, or interest on
Designated Senior Indebtedness (as defined below) beyond any applicable grace
period (a "Payment Default") until such Payment Default shall have been cured or
waived in writing or shall have ceased to exist or such Designated Senior
Indebtedness shall have been discharged or paid in full in cash or cash
equivalents.

         No payment or distribution of any assets of ResMed of any kind or
character, whether in cash, property or securities (other than Permitted Junior
Securities), may be made by or on behalf of ResMed on account of principal of,
premium, if any, or interest on the notes or on account of the purchase,
redemption or other acquisition of notes for the period specified below (a
"Payment Blockage Period") upon the occurrence of any default or event of
default with respect to any Designated Senior Indebtedness other than any
Payment Default pursuant to which the maturity thereof may be accelerated (a
"Non-Payment Default") and receipt by the trustee of written notice thereof from
the trustee or other representative of holders of Designated Senior
Indebtedness.

         The Payment Blockage Period will commence upon the date of receipt by
the trustee of written notice from the trustee or such other representative of
the holders of the Designated Senior Indebtedness in respect of which the
Non-Payment Default exists and shall end on the earliest of:

         (1)   179 days thereafter (provided that any Designated Senior
               Indebtedness as to which notice was given shall not theretofore
               have been accelerated);

         (2)   the date on which such Non-Payment Default is cured, waived or
               ceases to exist;

         (3)   the date on which such Designated Senior Indebtedness is
               discharged or paid in full; or

         (4)   the date on which such Payment Blockage Period shall have been
               terminated by written notice to the trustee or ResMed from the
               trustee or such other representative initiating such Payment
               Blockage Period,

after which ResMed will resume making any and all required payments in respect
of the notes, including any missed payments. In any event, not more than one
Payment Blockage Period may be commenced during any period of 365 consecutive
days. No Non-Payment Default that existed or was continuing on the date of the
commencement of any Payment Blockage Period will be, or can be made, the basis
for the commencement of a subsequent Payment Blockage Period, unless such
Non-Payment Default has been cured or waived for a period of not less than 90
consecutive days subsequent to the commencement of such initial Payment Blockage
Period.

         In the event that, notwithstanding the provisions of the preceding four
paragraphs, any payment or distribution shall be received by the trustee or any
holder of the notes which is prohibited by such provisions, then and in such
event such payment shall be paid over and delivered by such trustee or holder to
the trustee or any other representatives of holders of Senior Indebtedness, as
their interest may appear, for application to Senior Indebtedness. After all
Senior Indebtedness is paid in full and until the notes are paid in full,
holders of the notes shall be subrogated (equally and ratably with all other
indebtedness that is equal in right of payment to the notes) to the rights of
holders of Senior Indebtedness to receive distributions applicable to Senior
Indebtedness to the extent that distributions otherwise payable to the holders
of the notes have been applied to the payment of Senior Indebtedness.

         Failure by ResMed to make any required payment in respect of the notes
when due or within any applicable grace period, whether or not occurring during
a Payment Blockage Period, will result in an Event of Default and, thereafter,
holders of the notes will have the right to accelerate the maturity thereof. See
"-- Events of Default."

         By reason of such subordination, in the event of liquidation,
receivership, reorganization or insolvency of ResMed, our general creditors may
recover less, ratably, than holders of senior debt and such general creditors
may recover more, ratably, than holders of notes. Moreover, the notes will be
structurally subordinated to the liabilities of subsidiaries of ResMed.

         "Designated Senior Indebtedness:" means:

         .     all Senior Indebtedness under our existing revolving credit
               facility, as amended from time to time; and

         .     any other Senior Indebtedness which, at the time of
               determination, has an aggregate principal amount outstanding of
               at least $20 million and that has been specifically designated in
               the instrument evidencing such Senior Indebtedness as "Designated
               Senior Indebtedness" of ResMed.

                                       20


          "indebtedness" means, with respect to any person, without duplication:

          .    all liabilities of such person for borrowed money (including
               overdrafts) or for the deferred purchase price of property or
               services, excluding any trade payables and other accrued current
               liabilities incurred in the ordinary course of business, but
               including, without limitation, all obligations, contingent or
               otherwise, of such person in connection with any letters of
               credit and acceptances issued under letter of credit facilities,
               acceptance facilities or other similar facilities;

          .    all obligations of such person evidenced by bonds, notes, notes
               or other similar instruments;

          .    indebtedness of such person created or arising under any
               conditional sale or other title retention agreement with respect
               to property acquired by such person (even if the rights and
               remedies of the seller or lender under such agreement in the
               event of default are limited to repossession or sale of such
               property), but excluding trade payables arising in the ordinary
               course of business;

          .    all capitalized lease obligations of such person;

          .    all obligations of such person under or in respect of interest
               rate agreements or currency agreements;

          .    all indebtedness referred to in (but not excluded from) the
               preceding clauses of other persons and all dividends of other
               persons, the payment of which is secured by (or for which the
               holder of such indebtedness has an existing right, contingent or
               otherwise, to be secured by) any lien or with respect to property
               (including, without limitation, accounts and contract rights)
               owned by such person, even though such person has not assumed or
               become liable for the payment of such indebtedness (the amount of
               such obligation being deemed to be the lesser of the value of
               such property or asset or the amount of the obligation so
               secured);

          .    all guarantees by such person of indebtedness referred to in this
               definition or of any other person;

          .    all Redeemable Capital Stock of such person valued at the greater
               of its voluntary or involuntary maximum fixed repurchase price
               plus accrued and unpaid dividends; and

          .    the present value of the obligation of such person as lessee for
               net rental payments (excluding all amounts required to be paid on
               account of maintenance and repairs, insurance, taxes,
               assessments, water, utilities and similar charges to the extent
               included in such rental payments) during the remaining term of
               the lease included in such sale and leaseback transaction
               including any period for which such lease has been extended or
               may, at the option of the lessor, be extended. Such present value
               shall be calculated using a discount rate equal to the rate of
               interest implicit in such transaction, determined in accordance
               with accounting principles generally accepted in the United
               States.

          "Redeemable Capital Stock" means any class of our capital stock that,
either by its terms, by the terms of any securities into which it is convertible
or exchangeable or by contract or otherwise, is, or upon the happening of an
event or passage of time would be, required to be redeemed (whether by sinking
fund or otherwise) prior to the date that is 91 days after the final scheduled
maturity of the notes or is redeemable at the option of the holder thereof at
any time prior to such date, or is convertible into or exchangeable for debt
securities at any time prior to such date (unless it is convertible or
exchangeable solely at our option).

          "Senior Indebtedness" means:

          .    all obligations of ResMed, now or hereafter existing, under or in
               respect of our existing revolving credit facility, as amended
               from time to time, and the documents and instruments executed in
               connection therewith, whether for principal, premium, if any,
               interest (including interest accruing after the filing of, or
               which would have accrued but for the filing of, a petition by or
               against ResMed under bankruptcy law, whether or not such interest
               is allowed as a claim after such filing in any proceeding under
               such law) and other amounts due in connection therewith
               (including, without limitation, any fees, premiums, expenses,
               reimbursement obligations with respect to letters of credit and
               indemnities), whether outstanding on the date of the indenture or
               thereafter created, incurred or assumed; and

          .    the principal of, premium, if any, and interest on all other
               indebtedness of ResMed (other than the notes), whether
               outstanding on the date of the indenture or thereafter created,
               incurred or assumed, unless, in the case of any particular
               indebtedness, the instrument creating or evidencing the same or
               pursuant to which the same is outstanding expressly provides that
               such indebtedness shall not be senior in right of payment to the
               notes.

          Notwithstanding the foregoing, "Senior Indebtedness" shall not
          include:

          .    indebtedness evidenced by the notes;

                                       21



         .     indebtedness of ResMed that by operation of law is subordinate to
               any general unsecured obligations of ResMed;

         .     any liability for federal, state or local taxes or other taxes,
               owed or owing by ResMed;

         .     accounts payable or other liabilities owed or owing by ResMed to
               trade creditors (including guarantees thereof or instruments
               evidencing such liabilities);

         .     amounts owed by ResMed for compensation to employees or for
               services rendered to ResMed;

         .     indebtedness of ResMed to any subsidiary or any other affiliate
               of ResMed or any of such affiliate's subsidiaries;

         .     capital stock of ResMed;

         .     indebtedness evidenced by any guarantee of any indebtedness
               ranking equal or junior in right of payment to the notes; and

         .     indebtedness which, when incurred and without respect to any
               election under Section 1111(b) of Title 11 of the United States
               Code, is without recourse to ResMed.

         The notes will also be effectively subordinated to all liabilities,
including trade payables and lease obligations, if any, of our subsidiaries. Any
right by us to receive the assets of any of our subsidiaries upon the
liquidation or reorganization thereof (and the consequent right of the holders
of the notes to participate in these assets) will be effectively subordinated to
the claims of that subsidiary's creditors (including trade creditors), except to
the extent that we are recognized as a creditor of such subsidiary, in which
case our claims would still be subordinate to any security interests in the
assets of such subsidiary and any indebtedness of such subsidiary senior to that
held by us.

         Our subsidiaries are separate and distinct legal entities and have no
obligation, contingent or otherwise, to pay any amounts due pursuant to the
notes or to make any funds available therefor, whether by dividends, loans or
other payments. In addition, the payment of dividends and the making of loans
and advances to us by our subsidiaries may be subject to statutory, contractual
or other restrictions and are dependent upon the earnings or financial condition
of those subsidiaries and subject to various business considerations. As a
result, we may be unable to gain access to the cash flow or assets of our
subsidiaries.

         The indenture will not limit the amount of additional indebtedness,
including Senior Indebtedness, which we can create, incur, assume or guarantee,
nor will the indenture limit the amount of indebtedness or other liabilities
that our subsidiaries can create, incur, assume or guarantee. We are obligated
to pay reasonable compensation to the trustee and to indemnify the trustee
against certain losses, liabilities or expenses incurred by it in connection
with its duties relating to the notes. The trustee's claims for such payments
will generally be senior to those of the holders of the notes in respect of all
funds collected or held by the trustee.

Event of Default

         Each of the following constitutes an event of default under the
indenture:

         1.    our failure to pay when due the principal of or premium, if any,
               on any of the notes at maturity, upon redemption or exercise of a
               repurchase right or otherwise, whether or not such payment is
               prohibited by the subordination provisions of the indenture;

         2.    our failure to pay an installment of interest (including
               liquidated damages, if any) on any of the notes that continues
               for 30 days after the date when due, whether or not such payment
               is prohibited by the subordination provisions of the indenture;

         3.    our failure to deliver shares of common stock, together with cash
               instead of fractional shares, when those shares of common stock
               or cash instead of fractional shares are required to be delivered
               upon conversion of a note, and failure that continues for ten
               days after such delivery date;

         4.    our failure to perform or observe any other term, covenant or
               agreement contained in the notes or the indenture for a period of
               60 days after written notice of such failure, requiring us to
               remedy the same, shall have been given to us by the trustee or to
               us and the trustee by the holders of at least 25% in aggregate
               principal amount of the notes then outstanding;

         5.    our failure to make any payment by the end of the applicable
               grace period, if any, after the maturity of any indebtedness for
               borrowed money in an amount in excess of $5 million, or there is
               an acceleration of indebtedness for borrowed money in an amount
               in excess of $5 million because of a default with respect to such
               indebtedness without such

                                       22



               indebtedness having been discharged or such acceleration having
               been cured, waived, recorded or annulled, in either case, for a
               period of 30 days after written notice to us by the trustee or to
               us and the trustee by holders of at least 25% in aggregate
               principal amounts of the notes then outstanding;

         6.    certain events of our bankruptcy, insolvency or reorganization or
               that of any significant subsidiaries; and

         7.    our filing of a voluntary petition seeking liquidation,
               reorganization arrangement, readjustment of debts or for any
               other relief under the Federal bankruptcy code.

         The indenture provides that the trustee shall, within 90 days of the
occurrence of a default, give to the registered holders of the notes notice of
all uncured defaults known to it, but the trustee shall be protected in
withholding such notice if it, in good faith, determines that the withholding of
such notice is in the best interest of such registered holders, except in the
case of a default in the payment of the principal of, or premium, if any, or
interest on, any of the notes when due or in the payment of any redemption or
repurchase obligation.

         If an event of default specified in clause (6) or clause (7) above
occurs and is continuing, then automatically the principal of all the notes and
the interest thereon shall become immediately due and payable. If an event of
default shall occur and be continuing, other than with respect to clause (6) or
clause (7) above (the default not having been cured or waived as provided under
"-- Modifications and Waiver" below), the trustee or the holders of at least 25%
in aggregate principal amount of the notes then outstanding may declare the
notes due and payable at their principal amount together with accrued interest,
and thereupon the trustee may, at its discretion, proceed to protect and enforce
the rights of the holders of notes by appropriate judicial proceedings. Such
declaration may be rescinded or annulled with the written consent of the holders
of a majority in aggregate principal amount of the notes then outstanding upon
the conditions provided in the indenture.

         The indenture contains a provision entitling the trustee, subject to
the duty of the trustee during default to act with the required standard of
care, to be indemnified by the holders of notes before proceeding to exercise
any right or power under the indenture at the request of such holders. The
indenture provides that the holders of a majority in aggregate principal amount
of the notes then outstanding through their written consent may direct the time,
method and place of conducting any proceeding for any remedy available to the
trustee or exercising any trust or power conferred upon the trustee.

         We will be required to furnish annually to the trustee a statement as
to the fulfillment of our obligations under the indenture.

Consolidation, Mergers and Sales of Assets

         We may, without the consent of the holders of notes, consolidate with,
merge into or transfer all or substantially all of our assets to any
corporation, limited liability company, partnership or trust organized under the
laws of the United States or any of its political subdivisions provided that:

         .     the surviving corporation assumes all our obligations under the
               indenture and the notes;

         .     at the time of such transaction, no event of default, and no
               event which, after notice or lapse of time, would become an event
               of default, shall have happened and be continuing; and

         .     an officers' certificate and an opinion of counsel, each stating
               that the consolidation, merger or transfer complies with the
               provisions of the indenture, have been delivered to the trustee.

Modifications and Waiver

         The indenture (including the terms and conditions of the notes) may be
modified or amended by us and the trustee, without the consent of the holder of
any note, for the purposes of, among other things:

         .     adding to our covenants for the benefit of the holders of notes;

         .     surrendering any right or power conferred upon us;

         .     providing for conversion rights of holders of notes if any
               reclassification or change of our common stock or any
               consolidation, merger or sale of all or substantially all of our
               assets occurs;

         .     providing for the assumption of our obligations to the holders of
               notes in the case of a merger, consolidation, conveyance,
               transfer or lease;

                                       23


     .    reducing the conversion price, provided that the reduction will not
          adversely affect the interests of holders of notes in any material
          respect;

     .    complying with the requirements of the SEC in order to effect or
          maintain the qualification of the indenture under the Trust Indenture
          Act of 1939, as amended;

     .    making any changes or modifications to the indenture necessary in
          connection with the registration of the notes under the Securities Act
          as contemplated by the registration rights agreement, provided that
          this action does not adversely affect the interests of the holders of
          the notes in any material respect;

     .    curing any ambiguity or correcting or supplementing any defective
          provision contained in the indenture; provided that such modification
          or amendment does not, in the good faith opinion of our board of
          directors and the trustee, adversely affect the interests of the
          holders of the notes in any material respect; or

     .    adding or modifying any other provisions which we and the trustee may
          deem necessary or desirable and which will not adversely affect the
          interests of the holders of notes in any material respect.

     Modifications and amendments to the indenture or to the terms and
conditions of the notes may also be made, and noncompliance by us may be waived,
with the written consent of the holders of at least a majority in aggregate
principal amount of the notes at the time outstanding or by the adoption of a
resolution at a meeting of holders at which a quorum is present by at least a
majority in aggregate principal amount of the notes represented at the meeting.

     However, no such modification, amendment or waiver may, without the written
consent of the holder of each note affected:

     .    change the maturity of the principal of or any installment of interest
          on any note (including any payment of liquidated damages);

     .    reduce the principal amount of, or any premium, if any, or interest on
          (including the amount of liquidated damages), any note;

     .    reduce the interest rate or interest (including any liquidated
          damages) on any note;

     .    change the currency of payment of principle of, premium, if any, or
          interest in any note;

     .    impair the right to institute suit for the enforcement of any payment
          on or with respect to, or conversion of, any note;

     .    except as otherwise permitted or contemplated by provisions of the
          indenture concerning corporate reorganizations, adversely affect the
          repurchase option of holders upon a change of control or the
          conversion rights of holders of the notes;

     .    modify the subordination provisions of the notes in a manner adverse
          to the holders of notes; or

     .    reduce the percentage in aggregate principal amount of notes
          outstanding necessary to modify or amend the indenture or to waive any
          past default.

Satisfaction and Discharge

     We may discharge our obligations under the indenture while notes remain
outstanding, subject to certain conditions, if:

     .    all outstanding notes will become due and payable at their scheduled
          maturity within one year; or

     .    all outstanding notes are scheduled for redemption within one year;

and, in either case, we have deposited with the trustee an amount sufficient to
pay and discharge all outstanding notes on the date of their scheduled maturity
or the scheduled date of redemption; provided that we shall remain obligated to
issue shares upon conversion of the notes.

Global Notes, Book-Entry Form

     The notes were initially offered and sold solely to (i) "qualified
institutional buyers," as defined in Rule 144A under the Securities Act
("QIBs"), or (ii) investors ("Regulation S Investors") who are not "United
States persons" (as such term is defined under Regulation S under the Securities
Act) who acquire their notes in compliance with Regulation S. Except as noted
below, all

                                       24



notes are evidenced by one or more global notes (each, a "global note"). Each
global note is deposited with, or on behalf of, DTC and registered in the name
of Cede & Co. ("Cede") as DTC's nominee.

     QIBs may hold their interests in a global note directly through DTC if such
holder is a participant in DTC or indirectly through organizations which are
participants in DTC. QIBs who are not participants may beneficially own
interests in global notes held by DTC only through participants or certain
banks, brokers, dealers, trust companies and other parties that clear through or
maintain a custodial relationship with a participant, either directly or
indirectly.

     Regulation S Investors may hold their interests in a global note directly
through Morgan Guaranty Trust Company of New York, Brussels office, as operator
of the Euroclear System, or Clear-stream Banking, if they are participants in
these systems, or indirectly through organizations that are participants in
these systems. Euroclear and/or Clearstream Banking will hold interests in
global notes on behalf of their participants through their respective
depositaries, which in turn will hold the interests in global notes in
customers' securities accounts in the depositaries' names on the books of DTC.
Citibank, N.A., is acting initially as depositary for Clearstream Banking, and
The Chase Manhattan Bank is acting initially as depositary for Euroclear.

     So long as Cede, as the nominee of DTC, is the registered owner of the
global notes, Cede for all purposes will be considered the sole holder of the
global notes. Except as provided below and except in certain limited
circumstances as provided in the indenture, owners of beneficial interests in
the global notes will not be entitled to have certificates registered in their
names, will not receive or be entitled to receive physical delivery of
certificates in definitive form, and will not be considered record holders
thereof.

     Payment of interest on and the redemption price or repurchase price of a
global note will be made to Cede, the nominee for DTC, as the registered owner
of such global note by wire transfer of immediately available funds on each
interest payment date or redemption date, as the case may be. Neither we, the
trustee nor any paying agent will have any responsibility or liability for any
aspect of the records relating to or payments made on account of beneficial
ownership interests in a global note or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

     We have been informed by DTC that, with respect to any payment of interest
on, or the redemption price of, a global note, DTC's practice is to credit
participants' accounts on the payment date therefor with payments in amounts
proportionate to their respective beneficial interests in the principal amount
represented by such global note as shown on the records of DTC, unless DTC has
reason to believe that it will not receive payment on such payment date.
Payments by participants to owners of beneficial interests in the principal
amount represented by a global note held through such participants will be the
responsibility of such participants, as is now the case with securities held for
the accounts of customers registered in "street name."

     Because DTC can only act on behalf of participants, who in turn act on
behalf of indirect participants and certain banks, the ability of a person
having a beneficial interest in the principal amount represented by a global
note to pledge such interest to persons or entities that do not participate in
the DTC system, or otherwise take actions in respect of such interest, may be
affected by the lack of a physical certificate evidencing such interest.

     Participants in DTC will effect transfers with other participants in the
ordinary way in accordance with DTC rules and will settle transfers in same-day
funds. Participants in Euroclear and Clearstream Banking will effect transfers
with other participants in the ordinary way in accordance with the rules and
operating procedures of Euroclear and Clearstream Banking, as applicable.

     Cross-market transfers between DTC, on the one hand, and directly or
indirectly through Euroclear or Clearstream Banking participants, on the other,
will be effected in DTC in accordance with DTC rules on behalf of Euroclear or
Clearstream Banking, as the case may be, by its respective depositary; however,
these cross-market transactions will require delivery of instructions to
Euroclear or Clearstream Banking, as the case may be, by the counterparty in the
system in accordance with its rules and procedures and within its established
deadlines (Brussels time). Euroclear or Clearstream Banking, as the case may be,
will, if the transaction meets its settlement requirements, deliver instruction
to its respective depositary to take action to effect final settlement on its
behalf by delivering or receiving interests in a global note in DTC, and making
or receiving payment in accordance with normal procedures for same-day funds
settlement applicable to DTC. Euroclear participants and Clearstream Banking
participants may not deliver instructions directly to the depositaries for
Euroclear or Clearstream Banking.

     Because of time zone differences, the securities account of Euroclear or
Clearstream Banking participant purchasing an interest in a global note from a
DTC participant will be credited during the securities settlement processing day
(which must be a business day for Euroclear or Clearstream Banking, as the case
may be) immediately following the DTC settlement date, and the credit of any
transactions interests in a global note settled during the processing day will
be reported to the relevant Euroclear or Clearstream Banking participant on that
day. Cash received in Euroclear or Clearstream Banking as a result of sales of
interests in a


                                       25



global note by or through a Euroclear or Clearstream Banking participant to a
DTC participant will be received with value on the DTC settlement date, but will
be available in the relevant Euroclear or Clearstream Banking cash account only
as of the business day following settlement in DTC.

     Neither we nor the trustee (or any registrar, paying agent or conversion
agent under the indenture) will have any responsibility for the performance by
DTC, Euroclear or Clearstream Banking or any of their respective participants or
indirect participants of their respective obligations under the rules and
procedures governing their operations. DTC has advised us that it will take any
action permitted to be taken by a holder of notes (including, without
limitation, the presentation of notes for exchange as described below), only at
the direction of one or more participants to whose account with DTC interests in
a global note are credited, and only in respect of the principal amount of the
notes represented by such global note as to which such participant or
participants has or have given such direction.

     DTC has advised us as follows: DTC is a limited purpose trust company
organized under the laws of the State of New York, a member of the Federal
Reserve System, a "clearing corporation" within the meaning of the Uniform
Commercial Code and a "clearing agency" registered pursuant to the provisions of
Section 17A of the Exchange Act. DTC was created to hold securities for its
participants and to facilitate the clearance and settlement of securities
transactions between participants through electronic book-entry changes to the
accounts of its participants, thereby eliminating the need for physical movement
of certificates. Participants include securities brokers and dealers, banks,
trust companies and clearing corporations and may include certain other
organizations such as the initial purchasers. Certain of such participants (or
their representatives), together with other entities, own DTC. Indirect access
to the DTC system is available to others such as banks, brokers, dealers and
trust companies that clear through, or maintain a custodial relationship with a
participant, either directly or indirectly.

     Certificated Notes. Although we expect that DTC, Euroclear and Clearstream
Banking will agree to the foregoing procedures in order to facilitate transfers
of interests in global notes among participants of DTC, Euroclear, and
Clearstream Banking, DTC, Euroclear and Clearstream Banking are under no
obligation to perform or continue to perform these procedures, and these
procedures may be discontinued at any time. If DTC is at any time unwilling or
unable to continue as depositary and a successor depositary is not appointed by
us within 90 days, we will cause notes to be issued in definitive registered
form in exchange for interests in the global notes.

     Certificated notes will also be issued in connection with transfers to us
and to our affiliates.

     Restrictions on Transfer; Legends. The notes will be subject to certain
transfer restrictions as described below under "Notice to Investors" and
certificates evidencing the notes will bear a legend to such effect.

Governing Law

     The indenture and the notes will be governed by, and construed in
accordance with, the law of the State of New York.

Information Concerning the Trustee

     American Stock Transfer & Trust Company, as trustee under the indenture,
has been appointed by us as paying agent, conversion agent, registrar and
custodian with regard to the notes. American Stock Transfer & Trust Company is
also the transfer agent and registrar for our common stock. The trustee or its
affiliates may from time to time in the future provided banking and other
services to us in the ordinary course of their business.

Registration Rights

     On June 20, 2001, we entered into a registration rights agreement with the
initial purchasers that required us to file a registration statement relating to
the notes and the common stock issuable upon conversion of the notes on or
before October 1, 2001. We have filed the registration statement containing this
prospectus to satisfy our obligations under the registration rights agreement. A
holder who sells notes or common stock pursuant to the registration statement
generally will be required to be named as a selling stockholder in this
prospectus or a related prospectus supplement, to deliver a prospectus to the
subsequent purchasers and will be bound by the provisions of the registration
rights agreement, which are applicable to that holder (including certain
indemnification provisions).

     We are required to keep the registration statement effective until the
earlier of (A) such date that is two years after the last date of original
issuance of any of the notes; (B) the date when the holders of the notes and the
common stock issuable upon


                                       26



conversion of the notes are able to sell all such securities immediately without
restriction pursuant to the volume limitation provisions of Rule 144 under the
U.S. Securities Act of 1933 or any successor rule thereto or otherwise; or (C)
the sale pursuant to the shelf registration statement of all securities
registered thereunder.

     We are permitted to suspend the use of this prospectus under certain
circumstances relating to pending corporate developments, public filings with
the SEC and similar events for a period not to exceed 45 days in any three-month
period and not to exceed an aggregate of 90 days in any 12-month period.

     The summary herein of provisions of registration rights agreement is
subject to, and is qualified in its entirety by reference to, all of the
provisions of the registration rights agreement, a copy of which is available
upon request to us.


                                       27



                          DESCRIPTION OF CAPITAL STOCK

     The following description of our capital stock, as amended or superseded by
any applicable prospectus supplement, includes a summary of certain provisions
of our restated certificate of incorporation and our restated by-laws. This
description is subject to the detailed provisions of, and is qualified by
reference to, our certificate of incorporation and our by-laws, copies of which
have been filed as exhibits to the registration statement and which this
prospectus is a part.

     Our authorized capital stock consists of 100,000,000 shares of common
stock, $0.004 par value, and 2,000,000 shares of Preferred Stock, $0.01 par
value and 250,000 shares of Series A Junior Participating Preferred Stock, $0.01
par value. At September 7, 2001, 31,870,060 shares of common stock only were
issued and outstanding.

Common Stock

     Holders of our common stock are entitled to one vote for each share held on
all matters submitted to a vote of stockholders and do not have cumulative
voting rights. Accordingly, holders of a majority of the shares of common stock
entitled to vote in any election of directors may elect all of the directors
standing for election. Holders of common stock are entitled to receive ratably
such dividends, if any, as may be declared by the board of directors out of
funds legally available therefor, subject to any preferential dividend rights of
outstanding preferred stock. Upon our liquidation, dissolution or winding up,
the holders of common stock are entitled to receive ratably our net assets
available after the payment of all debts and other liabilities and subject to
the prior rights of any outstanding preferred stock. Holders of our common stock
have no preemptive, subscription, redemption or conversion rights. The
outstanding shares of common stock are fully paid and nonassessable. The rights,
preferences and privileges of holders of common stock are subject to and may be
adversely affected by, the rights of the holders of shares of any series of
preferred stock which we have designated and issued or may designate and issue
in the future.

Preferred Stock

     Our board of directors is authorized, without stockholder approval, but
subject to any limitations prescribed by law, to issue up to 2,000,000 shares of
preferred stock, in one or more series. Each such series will have such rights,
preferences, privileges and restrictions, including voting rights, dividend
rights, conversion rights, redemption privileges and liquidation preferences, as
will be determined by the board of directors.

Rights Plan

     On April 15, 1997, our board of directors declared a dividend of one
preferred stock purchase right for each share of common stock, par value $0.004
per share, outstanding at the close of business on April 30, 1997, the record
date. As long as the rights are attached to our common stock, we will issue one
right (subject to adjustment) with each new share of common stock so that all
shares of common stock will have attached rights. When exercisable, each right
will entitle the registered holder to purchase from us one one-hundredth of a
share of Series A Junior Participating Preferred Stock at a price of $80.00 per
one one-hundredth of a share of Series A Junior Participating Preferred Stock,
subject to adjustment. The description and terms of the rights are set forth in
a rights agreement, dated as of April 23, 1997, as amended by a first amendment
to rights agreement, dated as of March 19, 1999 and a second amended rights
agreement dated as of January 23, 2001, as the same may be amended from time to
time, between us and American Stock Transfer & Trust Company, as Rights Agent.

Delaware Law and Certain Charter and By-Law Provisions

     We are subject to the provisions of Section 203 of the General Corporation
Law of Delaware. Section 203 prohibits a publicly held Delaware corporation from
engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person
became an interested stockholder, unless the business combination is approved in
a prescribed manner. A "business combination" includes mergers, asset sales and
other transactions resulting in a financial benefit to the interested
stockholders. Subject to certain exceptions an "interested stockholder" is a
person who, together with affiliates and associates, owns, or within three years
did own, 15% or more of the corporation's voting stock.

     Our restated certificate of incorporation and restated by-laws, as amended,
provide for the division of the board of directors into three classes as nearly
equal in size as possible with staggered three-year terms. Under the restated
by-laws, any vacancy on the board of directors, except for a vacancy occurring
as a result of the removal of directors without cause, may be filled by vote of
a majority of directors then in office or may be filled by the stockholders. Any
vacancy occurring as a result of the removal of a director by the stockholders
without cause shall be filled by the stockholders. The classification of the
board of directors and the limitation on


                                       28



the filling of vacancies could have the effect of making it more difficult for a
third party to acquire, or of discouraging a third party from acquiring, control
of us.

     Our restated certificate of incorporation contains certain provisions
permitted under the General Corporation Law of Delaware (the "Delaware
Corporation Law") relating to the liability of directors. The provisions
eliminate a director's liability for monetary damages for a breach of fiduciary
duty, except in certain circumstances involving wrongful acts, such as the
breach of a director's duty of loyalty or acts or omissions which involve
intentional misconduct or a knowing violation of law. Further, the restated
certificate of incorporation contains provisions to indemnify our directors and
officers to the fullest extent permitted by the Delaware Corporation Law. We
believe that these provisions will assist us in attracting or retaining
qualified individuals to serve as directors.

                 UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

     The following is a summary of certain United States federal income and
estate tax considerations relating to the purchase, ownership and disposition of
the notes and common stock into which notes may be converted, but does not
purport to be a complete analysis of all the potential tax considerations
relating thereto. This summary is based on laws, regulations, rulings and
decisions now in effect, all of which are subject to change or differing
interpretation possibly with retroactive effect. We have not sought any ruling
from the Internal Revenue Service or an opinion of counsel with respect to the
statements made and the conclusions reached in the following summary, and there
can be no assurance that the Internal Revenue Service will agree with such
statements and conclusions.

     This discussion is limited to holders who purchase notes upon their initial
issuance at their "issue price" within the meaning of Section 1273 of the
Internal Revenue Code of 1986, as amended, and who hold the notes and the common
stock into which such notes are convertible as capital assets. This discussion
also does not address the tax considerations arising under the laws of any
foreign, state or local jurisdiction. In addition, this discussion does not
address tax considerations applicable to an investor's particular circumstances
or to investors that may be subject to special tax rules, including, without
limitation:

     .    banks;

     .    holders subject to the alternative minimum tax;

     .    tax-exempt organizations;

     .    insurance companies;

     .    foreign persons or entities (except to the extent specifically set
          forth below);

     .    dealers in securities or currencies;

     .    persons that will hold notes as a position in a hedging transaction,
          "straddle" or "conversion transaction" for tax purposes; or

     .    persons deemed to sell notes or common stock under the constructive
          sale provisions of the Internal Revenue Code.

     YOU ARE URGED TO CONSULT YOUR TAX ADVISOR WITH RESPECT TO THE APPLICATION
OF THE UNITED STATES FEDERAL INCOME TAX LAWS TO YOUR PARTICULAR SITUATION AS
WELL AS ANY TAX CONSEQUENCES ARISING UNDER THE FEDERAL ESTATE OR GIFT TAX RULES
OR UNDER THE LAWS OF ANY STATE, LOCAL, FOREIGN OR OTHER TAXING JURISDICTION OR
UNDER ANY APPLICABLE TAX TREATY.

U.S. Holders

     For  purposes of this summary, a "U.S. holder" means:

     1.   an individual citizen or resident of the United States;

     2.   a corporation (or an entity treated as a corporation) created or
          organized in the United States or under the laws of the United States,
          any state thereof, or the District of Columbia;

     3.   an estate, the income of which is subject to United States federal
          income taxation regardless its source; or

     4.   a trust that (i) is subject to the primary supervision of a United
          States court and the control of one or more United States persons or
          (ii) has elected to be treated as a United States person under
          applicable Treasury Regulations.

In addition, if a holder is an entity treated as a partnership for United States
federal income tax purposes, the tax treatment of each partner of such
partnership will generally depend upon the status of the partner and upon the
activities of the partnership. Partners in partnerships which hold notes or
common stock should consult their tax advisors.

Taxation of Interest.

         You must include interest paid on the notes as ordinary income at the
time it is received or accrued, in accordance with your regular method of
accounting for United States federal income tax purposes.


                                       30



Sale, Exchange or Redemption of the Notes.

       Upon the sale, exchange (other than a conversion) or redemption of a
note, you generally will recognize capital gain or loss equal to the difference
between (i) the amount of cash proceeds and the fair market value of any
property received on the sale, exchange or redemption (except to the extent such
amount is attributable to accrued interest income not previously included in
income, which will be taxable as ordinary income, or is attributable to accrued
interest that was previously included in income, which amount may be received
without generating further income) and (ii) your adjusted tax basis in the note.
Your adjusted tax basis in a note generally will equal the cost of the note.
Such capital gain or loss will be long-term capital gain or loss if you have
held the note for more than one year at the time of sale, exchange or
redemption. Long-term capital gains recognized by certain noncorporate U.S.
holders, including individuals, will generally be subject to a maximum tax rate
of 20%. The deductibility of capital losses is subject to limitations.

Liquidated Damages.

       If we fail to register the notes with the SEC on a shelf registration
statement to permit you to resell your notes, we will be required to pay you
liquidated damages, as described above under "Description of Notes --
Registration Rights." We intend to take the position for United States federal
income tax purposes that any payments of liquidated damages should be taxable to
you as additional interest income when received or accrued, in accordance with
your method of tax accounting. This position is based in part on the assumption
that as of the date of issuance of the notes, the possibility that liquidated
damages will have to be paid is a "remote" or "incidental" contingency within
the meaning of applicable Treasury Regulations. Our determination that such
possibility is a remote or incidental contingency is binding on you, unless you
explicitly disclose that you are taking a different position to the Internal
Revenue Service on your tax return for the year during which you acquire the
note. However, the Internal Revenue Service may take a contrary position from
that described above, which could affect the timing and character of both your
income from the notes and our deduction with respect to the payments of
liquidated damages.

       If we do fail to file a registration statement, you should consult your
tax advisors concerning the appropriate tax treatment of the payment of
liquidated damages with respect to the notes.

Conversion of the Notes.

       You generally will not recognize any income, gain or loss upon conversion
of a note into common stock except with respect to cash received in lieu of a
fractional share of common stock. Your tax basis in the common stock received on
conversion of a note will be the same as your adjusted tax basis in the note at
the time of conversion (reduced by any basis allocable to a fractional share
interest), and the holding period for the common stock received on conversion
will generally include the holding period of the note converted. However, your
tax basis in shares of common stock considered attributable to accrued interest
generally will equal the amount of such accrued interest included in income, and
the holding period for such shares shall begin on the date of conversion.

       Cash received in lieu of a fractional share of our common stock upon
conversion will be treated as a payment in exchange for the fractional share of
common stock. Accordingly, you will generally recognize capital gain or loss
(measured by the difference between the cash received for the fractional share
and your adjusted tax basis in the fractional share) upon the receipt of cash in
lieu of a fractional share of common stock.

Dividends.

       Distributions, if any, made on our common stock after a conversion
generally will be included in your income as ordinary dividend income to the
extent of our current or accumulated earnings and profits. Distributions in
excess of our current and accumulated earnings and profits will be treated as a
return of capital to the extent of your basis in the common stock and thereafter
as capital gain.

       Holders of convertible debt instruments such as the notes may, in certain
circumstances, be deemed to have received distributions of stock if the
conversion price of such instruments is adjusted. However, adjustments to the
conversion price made pursuant to a bona fide reasonable adjustment formula
which has the effect of preventing the dilution of the interest of the holders
of the debt instruments will generally not be to result in a constructive
distribution of stock. Certain of the possible adjustments provided in the notes
(including, without limitation, adjustments in respect of taxable dividends to
our stockholders) will not qualify as being pursuant to a bona fide reasonable
adjustment formula. If such adjustments are made, you will be deemed to have
received constructive distributions taxable as dividends to the extent of our
current and accumulated earnings and profits even though you have

                                       31


not received any cash or property as a result of such adjustments. In certain
circumstances, the failure to provide for such an adjustment may result in
taxable dividend income to you.

Sale, Exchange or Redemption of Common Stock.

       Upon the sale, exchange or redemption of common stock you generally will
recognize capital gain or loss equal to the difference between (i) the amount of
cash and the fair market value of any property received upon the sale, exchange
or redemption and (ii) your adjusted tax basis in the common stock. Such capital
gain or loss will be long-term capital gain or loss if your holding period in
common stock is more than one year at the time of the sale, exchange or
redemption. Long-term capital gains recognized by certain non-corporate U.S.
holders, including individuals, will generally be subject to a maximum rate of
tax of 20%. Your basis and holding period in common stock received upon
conversion of a note are determined as discussed above under "Conversion of the
Notes." The deductibility of capital losses is subject to limitations.

Backup Withholding and Information Reporting.

       Backup withholding of United States federal income tax may apply to
payments pursuant to the terms of a note or common stock if you are a U.S.
holder and not an "exempt recipient" and if you fail to provide certain
identifying information (such as your TIN) in the manner required. Generally,
individuals are not exempt recipients. Corporations are exempt recipients,
whereas other entities may be exempt recipients. Payments made in respect of a
note or common stock must be reported to the Internal Revenue Service, unless
you are an exempt recipient or otherwise establish an exemption. Any amount
withheld from a payment to you under the backup withholding rules is allowable
as a refund or credit against your United States federal income tax, provided
that the required information is furnished to the Internal Revenue Service in a
timely manner.

Non-U.S. Holders

       For purposes of this discussion, a "non-U.S. holder" means a holder that
is not a U.S. holder. In general, subject to the discussion below concerning
backup withholding:

Taxation of Interest.

       If interest on the notes is not effectively connected with your conduct
of a trade or business in the United States, payments of principal or interest
on the notes by us or any paying agent to a beneficial owner of a note that is a
non-U.S. holder will not be subject to United States income or withholding tax,
provided that, in the case of interest:

       1.  you do not own, actually or constructively, 10% or more of the total
           combined voting power of all classes of our stock entitled to vote;

       2.  such non-U.S. holder is not a "controlled foreign corporation" with
           respect to which we are a "related person;"

       3.  you are not a bank receiving interest pursuant to a loan agreement
           entered into in the ordinary course of your trade or business; and

       4.  certain certification requirements are satisfied.

       To satisfy the certification requirements referred to in (4) above,
either (i) the beneficial owner of a note must certify, under penalties of
perjury, to us or our paying agent, as the case may be, that such owner is a
non-U.S. holder and must provide such owner's name and address, and United
States taxpayer identification number, if any, or (ii) a securities clearing
organization, bank or other financial institution that holds customer securities
in the ordinary course of its trade or business (a "Financial Institution") and
holds the note on behalf of the beneficial owner thereof must certify, under
penalties of perjury, to us or our paying agent, as the case may be, that such
certificate has been received from the beneficial owner and must furnish the
payor with a copy thereof. Such requirement will be fulfilled if the beneficial
owner of a note certifies on Internal Revenue Service Form W-8BEN or successor
form, under penalties of perjury, that it is a non-U.S. holder and provides its
name and address or any Financial Institution holding the note on behalf of the
beneficial owner files a statement with the withholding agent to the effect that
it has received such a statement from the beneficial owner (and furnishes the
withholding agent with a copy thereof). The applicable regulations generally
also require, in the case of a note held by a foreign partnership, that:

       1.  the certification described above be provided by the partners; and

       2.  the partnership provide certain information, including a United
           States taxpayer identification number.

                                       32




       Further, a look-through rule will apply in the case of tiered
partnerships. Prospective investors should consult their tax advisors regarding
the certification requirements for non-U.S. holders.

       Interest on notes not excluded from United States withholding tax as
described above generally will be subject to United States withholding tax at a
30% rate, except where an applicable United States income tax treaty provides
for the reduction or elimination of such withholding tax (and you provide the
appropriate certification) or if interest on the note is effectively connected
with your conduct of a trade or business in the United States, which is
described more fully below.

Sale, Exchange or Redemption of the Notes or Common Stock.

       You will not be required to pay United States federal income tax on gains
realized on the sale, exchange or redemption of such note or common stock
(except with respect to accrued and unpaid interest, which would be taxable as
described above) unless:

       1.  you are an individual who is present in the United States for 183
           days or more in the taxable year of sale, exchange or other
           disposition, and certain conditions are met;

       2.  such gain is effectively connected with your conduct of a trade or
           business in the United States and, if certain United States income
           tax treaties apply, is attributable to a United States permanent
           establishment maintained by you;

       3.  you are subject to provisions in the Internal Revenue Code applicable
           to certain United States expatriates; or

       4.  in the case of common stock held by you, we are or have been a
           "United States real property holding corporation" for United States
           federal income tax purposes at any time during the shorter of the
           five-year period ending on the date of disposition or period that you
           held our common stock. We do not believe that we are currently, and
           do not anticipate becoming, a United States real property
           corporation. Even if we were, or were to become, a United States real
           property holding corporation, no adverse tax consequences would apply
           to you if you hold, directly and indirectly, at all times during the
           applicable period, less than five percent of our common stock,
           provided that our common stock was regularly traded on an established
           securities market.

Conversion of the Notes.

       You generally should not be required to pay United States federal income
tax on the conversion of a note into common stock. To the extent you receive
cash in lieu of a fractional share of common stock upon conversion, you may be
subject to the rules described above with respect to the sale, exchange or
redemption of a note or common stock. See "Non-U.S. Holders -- Sale, Exchange or
Redemption of the Notes or Common Stock" above.

Dividends.

       Distributions on common stock after conversion will constitute a dividend
for United States federal income tax purposes to the extent of our current or
accumulated earnings and profits as determined under United States federal
income tax principles. Dividends generally will be subject to United States
withholding tax at a 30% rate, except where an applicable United States income
tax treaty provides for the reduction or elimination of such withholding tax or
where the dividends are effectively connected with the conduct of a trade or
business in the United States, which is more fully described below.

       The conversion price of the notes is subject to adjustment in certain
circumstances. Any such adjustment could, in certain circumstances, give rise to
a deemed distribution to you. See "U.S. Holders -- Dividends" above. In such
case, the deemed distribution would be subject to the rules described above
regarding United States withholding tax on dividends.

Income or Gains Effectively Connected With A United States Trade or Business.

       If you are engaged in a trade or business in the United States and if
interest on the note, dividends on the common stock, or gain realized on the
sale, exchange or other disposition of the note or common stock is effectively
connected with the conduct of such trade or business (and, if certain tax
treaties apply, is attributable to a United States permanent establishment
maintained by you in the United States), you, although exempt from United States
withholding tax (provided that the certification requirements discussed in the
next sentence are met), will generally be required to pay United States federal
income tax on such interest, dividends or gain on a net income basis in the same
manner as if you were a U.S. holder. In lieu of the certificate described above,
you would be required, under currently effective Treasury Regulations, to
provide us with a properly executed Internal Revenue Service Form W-8ECI or
successor form in order to claim an exemption from United States withholding
tax. In addition, if you are a foreign corporation, you may be

                                       33


subject to a branch profits tax equal to 30% (or such lower rate provided by an
applicable United States income tax treaty) of a portion of your effectively
connected earnings and profits for the taxable year.

United States Federal Estate Tax.

       A note held by an individual who at the time of death is not a citizen or
resident of the United States (as specially defined for United States federal
estate tax purposes) generally will not be subject to United States federal
estate tax if, at the time of the individual's death, the individual did not
actually or constructively own 10% or more of the total combined voting power of
all classes of our stock entitled to vote and payments with respect to such note
would not have been effectively connected with the conduct by such individual of
a trade or business in the United States. Common stock held by an individual who
at the time of death is not a citizen or resident of the United States (as
specially defined for United States federal estate tax purposes) will be
included in such individual's estate for United States federal estate tax
purposes, unless an applicable estate tax treaty otherwise applies.

Backup Withholding and Information Reporting.

       The amount of interest paid to you on the note and the amount of tax
withheld, if any, will generally be reported to you and the Internal Revenue
Service. You will generally not be subject to backup withholding with respect to
payments that we make to you provided that we do not have actual knowledge that
you are a United States person and you have made appropriate certifications as
to your foreign status, or you otherwise establish an exemption.

       You will generally not be subject to backup withholding or information
reporting with respect to any payment of the proceeds of the sale of a note
effected outside the United States by a foreign office of a foreign "broker" (as
defined in applicable Treasury Regulations), provided that such broker:

       .   derives less than 50% of its gross income for certain periods from
           the conduct of a trade or business in the United States,

       .   is not a controlled foreign corporation for United States federal
           income tax purposes, and

       .   is not a foreign partnership that, at any time during its taxable
           year, has 50% or more of its income or capital interests owned by
           United States persons or is engaged in the conduct of a United States
           trade or business.

       Subject to the discussion in the preceding paragraph, you will be subject
to information reporting, but not backup withholding, with respect to any
payment of the proceeds of a sale of a note effected outside the United States
by a foreign office of any other broker unless such broker has documentary
evidence in its records that you are not a United States person and certain
other conditions are met, or you otherwise establish an exemption. You will be
subject to backup withholding and information reporting with respect to any
payment of the proceeds of a sale of a note effected by the United States office
of a broker unless you properly certify under penalties of perjury as to your
foreign status and certain other conditions are met or you otherwise establish
an exemption.

       Any amounts withheld under the backup withholding rules will generally be
allowed as a refund or a credit against your United States federal income tax
liability provided the required information is furnished to the Internal Revenue
Service.

         THE PRECEDING DISCUSSION OF CERTAIN UNITED STATES FEDERAL INCOME AND
ESTATE TAX CONSIDERATIONS IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE.
ACCORDINGLY, YOU ARE URGED TO CONSULT YOUR TAX ADVISORS AS TO THE PARTICULAR TAX
CONSIDERATIONS TO YOU OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF THE NOTES
AND THE COMMON STOCK INTO WHICH THE NOTES ARE CONVERTIBLE, INCLUDING THE EFFECT
AND APPLICABILITY OF STATE, LOCAL, FOREIGN OR OTHER TAX LAWS, AS WELL AS THE
CONSEQUENCES OF ANY PROPOSED CHANGE IN APPLICABLE LAWS.

                                       34



                             SELLING SECURITYHOLDERS

         The notes were originally issued by ResMed and sold by the initial
purchasers of the notes in a transaction exempt from the registration
requirements of the Securities Act to persons reasonably believed by the initial
purchasers to be qualified institutional buyers or to be non-U.S. persons
outside the United States. Selling securityholders, including their transferees,
pledgees or donees or their successors, may from time to time offer and sell
pursuant to this prospectus any or all of the notes and shares of common stock
into which the notes are convertible.

         The following table sets forth information, as of September 27, 2001,
with respect to the selling securityholders and the principal amounts of notes
beneficially owned by each selling securityholder that may be offered pursuant
to this prospectus. The information is based on information provided by or on
behalf of the selling securityholders. The selling securityholders may offer
all, some or none of the notes or the common stock into which the notes are
convertible. Because the selling securityholders may offer all or some portion
of the notes or the common stock, we cannot estimate the amount of the notes or
the common stock that will be held by the selling securityholders upon
termination of any of these sales. In addition, the selling securityholders
identified below may have sold, transferred or otherwise disposed of all or a
portion of their notes since the date on which they provided the information
regarding their notes in transactions exempt from the registration requirements
of the Securities Act. The percentage of notes outstanding beneficially owned by
each selling securityholder is based on $180,000,000 aggregate principal amount
of notes outstanding. The number of shares of common stock owned prior to the
offering includes shares of common stock into which the notes are convertible.
The number of shares of common stock offered hereby is based on a conversion
price of $60.60 per share of common stock and a cash payment in lieu of any
fractional share. No selling securityholder named in the table below
beneficially owns one percent or more of our common stock, based on 31,870,060
shares of common stock outstanding on September 7, 2001. Information concerning
other selling securityholders will be set forth in prospectus supplements from
time to time, if required. The number of shares of common stock owned by the
other selling securityholders or any future transferee from any such holder
assumes that they do not beneficially own any common stock other than common
stock into which the notes are convertible at a conversion price of $60.60 per
share.

         None of the selling securityholders nor any of their affiliates,
officers, directors or principal equity holders has held any position or office
or has had any material relationship with ResMed within the past three years.

         The initial purchasers purchased all of the notes from us in a private
transaction in June 2001. All of the notes were "restricted securities" under
the Securities Act prior to this registration. The selling securityholders have
represented to us that they

                                       35



purchased the shares for their own account for investment only and not with a
view toward selling or distributing them, except pursuant to sales registered
under the Securities Act or exempt from such registration.

         Information concerning other selling securityholders will be set forth
in prospectus supplements from time to time, if required. Information concerning
the securityholders may change from time to time and any changed information
will be set forth in supplements to this prospectus if and when necessary. In
addition, the conversion price, and therefore, the number of shares of common
stock issuable upon conversion of the notes, is subject to adjustment under
certain circumstances. Accordingly, the aggregate principal amount of notes and
the number of shares of common stock into which the notes are convertible may
increase or decrease.

                                       36



                              PLAN OF DISTRIBUTION

     The selling securityholders and their successors, which term includes their
transferees, pledgees or donees or their successors may sell the notes and the
underlying common stock directly to purchasers or through underwriters,
broker-dealers or agents, who may receive compensation in the form of discounts,
concessions or commissions from the selling securityholders or the purchasers.
These discounts, concessions or commissions as to any particular underwriter,
broker-dealer or agent may be in excess of those customary in the types of
transactions involved.

     The common stock may be sold in one or more transactions at:

     .  fixed prices,

     .  prevailing market prices at the time of sale,

     .  prices related to the prevailing market prices,

     .  varying prices determined at the time of sale, or

     .  negotiated prices.

     These sales may be effected in transactions:

     .  on any national securities exchange or quotation service on which our
        common stock may be listed or quoted at the time of sale, including the
        Nasdaq National Market,

     .  in the over-the-counter market,

     .  otherwise than on such exchanges or services or in the over-the-counter
        market,

     .  through the writing of options, whether the options are listed on an
        options exchange or otherwise, or

     .  through the settlement of short sales.

These transactions may include block transactions or crosses. Crosses are
transactions in which the same broker acts as agent on both sides of the trade.

     In connection with the sale of the notes and the underlying common stock or
otherwise, the selling securityholders may enter into hedging transactions with
broker-dealers or other financial institutions. These broker-dealers or
financial institutions may in turn engage in short sales of the common stock in
the course of hedging the positions they assume with selling securityholders.
The selling securityholders may also sell the notes and the underlying common
stock short and deliver these securities to close out such short positions, or
loan or pledge the notes or the underlying common stock to broker-dealers that
in turn may sell these securities.

     The aggregate proceeds to the selling securityholders from the sale of the
notes or the underlying common stock offered by them hereby will be the purchase
price of the common stock less discounts and commissions, if any. Each of the
selling securityholders reserves the right to accept and, together with their
agents from time to time, to reject, in whole or in part, any proposed purchase
of common stock to be made directly or through agents. We will not receive any
of the proceeds from this offering.

     Our outstanding common stock is listed for trading on the NYSE. We do not
intend to list the notes for trading on any national securities exchange or on
the Nasdaq National Market and can give no assurance about the development of
any trading market for the notes.

     In order to comply with the securities laws of some states, if applicable,
the notes and the underlying common stock may be sold in these jurisdictions
only through registered or licensed brokers or dealers. In addition, in some
states the notes may not be sold unless they have been registered or qualified
for sale or an exemption from registration or qualification requirements is
available and is complied with.

     The selling securityholders and any broker-dealers or agents that
participate in the sale of the notes and the underlying common stock may be
deemed to be "underwriters" within the meaning of Section 2(l1) of the
Securities Act. Profits on the sale of the notes and the underlying common stock
by selling securityholders and any discounts, commissions or concessions
received by any broker-dealers or agents might be deemed to be underwriting
discounts and commissions under the Securities Act. Selling securityholders who
are deemed to be "underwriters" within the meaning of Section 2(l1) of the
Securities Act will be subject to the

                                       37



prospectus delivery requirements of the Securities Act. To the extent the
selling securityholders may be deemed to be "underwriters," they may be subject
to statutory liabilities, including, but not limited to, Sections 11, 12 and 17
of the Securities Act.

     The selling securityholders and any other person participating in a
distribution will be subject to applicable provisions of the Exchange Act and
the rules and regulations thereunder. Regulation M of the Exchange Act may limit
the timing of purchases and sales of any of the securities by the selling
securityholders and any other person. In addition, Regulation M may restrict the
ability of any person engaged in the distribution of the securities to engage in
market-making activities with respect to the particular securities being
distributed for a period of up to five business days before the distribution.
The selling securityholders have acknowledged that they understand their
obligations to comply with the provisions of the Exchange Act and the rules
thereunder relating to stock manipulation, particularly Regulation M, and have
agreed that they will not engage in any transaction in violation of such
provisions.

     To our knowledge, there are currently no plans, arrangements or
understandings between any selling securityholder and any underwriter,
broker-dealer or agent regarding the sale of the common stock by the selling
securityholders.

     A selling securityholder may decide not to sell any notes or the underlying
common stock described in this prospectus. We cannot assure you that any selling
securityholder will use this prospectus to sell any or all of the notes or the
underlying common stock. Any securities covered by this prospectus which qualify
for sale pursuant to Rule 144 or Rule 144A of the Securities Act may be sold
under Rule 144 or Rule 144A rather than pursuant to this prospectus. In
addition, a selling securityholder may transfer, devise or gift the notes and
the underlying common stock by other means not described in this prospectus.

     With respect to a particular offering of the notes and the underlying
common stock, to the extent required, an accompanying prospectus supplement or,
if appropriate, a post-effective amendment to the registration statement of
which this prospectus is a part will be prepared and will set forth the
following information:

     .  the specific notes or common stock to be offered and sold,

     .  the names of the selling securityholders,

     .  the respective purchase prices and public offering prices and other
        material terms of the offering,

     .  the names of any participating agents, broker-dealers or underwriters,
        and

     .  any applicable commissions, discounts, concessions and other items
        constituting, compensation from the selling securityholders.

     We entered into the registration rights agreement for the benefit of
holders of the notes to register their notes and the underlying common stock
under applicable federal and state securities laws under certain circumstances
and at certain times. The registration rights agreement provides that the
selling securityholders and ResMed will indemnify each other and their
respective directors, officers and controlling persons against specific
liabilities in connection with the offer and sale of the notes and the
underlying common stock, including liabilities under the Securities Act, or will
be entitled to contribution in connection with those liabilities. We will pay
all of our expenses and specified expenses incurred by the selling
securityholders incidental to the registration, offering and sale of the notes
and the underlying common stock to the public, but each selling securityholder
will be responsible for payment of commissions, concessions, fees and discounts
of underwriters, broker-dealers and agents.

                                  LEGAL MATTERS

     The validity of the issuance of the notes and the common stock issuable
upon conversion of the notes will be passed upon for us by Latham & Watkins,
Costa Mesa, California.

meaning of the Securities Act of 1933 and we are not subject to the information
reporting requirements of the Securities Exchange Act of 1934, we will furnish

144A(d)(4) under the Securities Act of 1933 to permit compliance with Rule 144A
in connection with resales of the notes and such common stock.

     We have filed with the SEC a registration statement on Form S-3 under the
Securities Act. This prospectus does not contain all of the information in the
registration statement. We have omitted certain parts of the registration
statement, as permitted by the rules and regulations of the SEC. You may inspect
and copy the registration statement, including exhibits, at the SEC's public

ITEM 15.  LIABILITY AND INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Section 145 of the Delaware Corporation Law gives Delaware corporations
broad powers to indemnify their present and former directors and officers
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred in connection with threatened,
pending or completed actions, suits or proceedings to which they are parties or
are threatened to be made parties by reason of being or having been such
directors or officers, subject to specified conditions and exclusions; gives a
director or officer who successfully defends an action the right to be so
indemnified; and permits a corporation to buy directors' and officers' liability
insurance. Such indemnification is not exclusive of any other rights to which
those indemnified may be entitled under any by-law, agreement, vote of
stockholders or otherwise.

         As permitted by Section 145 of the Delaware Corporation Law, Article VI
of our restated By-laws provides for the indemnification by us of our directors
and officers, employees and agents against liabilities and expenses incurred in
connection with actions, suits or proceeds brought against them by a third party
or in the right of the corporation, by reason of the fact that they were or are
such directors or officers. Article Sixth of our restated certificate of
incorporation provides that to the fullest extent permitted by the Delaware
Corporation Law as the same exists or may hereafter be amended, a director shall
not be liable to us or our stockholders for monetary damages for breach of
fiduciary duty as a director.

         We have entered into, or intend to enter into, agreements to indemnify
our directors and executive officers in addition to the indemnification provided
for in the restated certificate of incorporation and restated by-laws. These
agreements, among other things, will indemnify our directors and executive
officers for certain expenses (including attorneys' fees), and all losses,
claims, liabilities, judgments, fines and settlement amounts incurred by such
person arising out of or in connection with such person's service as one of our
directors or officers to the fullest extent permitted by applicable law.

         Policies of insurance may be obtained and maintained by us under which
our directors and officers will be insured, within the limits and subject to the
limitations of the policies, against certain expenses in connection with the
defense of, and certain liabilities which might be imposed as a result of,
actions, suits or proceedings to which they are parties by reason of being or
having been such directors or officers.

ITEM 17.  UNDERTAKINGS.

    A. The Company hereby undertakes:

        (1) To file, during any period in which offers or sales are being made,
    a post-effective amendment to this Registration Statement:

             (i)   To include any prospectus required by Section 10(a)(3) of the
    Securities Act;

             (ii)  To reflect in the prospectus any facts or events arising
    after the effective date of the Registration Statement (or the most recent
    post-effective amendment thereof) which, individually or in the aggregate,
    represent a fundamental change in the information set forth in the
    Registration Statement. Notwithstanding the foregoing, any increase or
    decrease in volume of securities offered (if the total increase or decrease
    in volume of securities offered would not exceed that which was registered)
    and any deviation from the low or high of the estimated maximum offering
    range may be reflected in the form of prospectus filed with the SEC
    pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
    price represent no more than 20 percent change in the maximum aggregate
    offering price, set forth in the "Calculation of Registration Fee" table in
    the effective registration statement;

             (iii) To include any material information with respect to the plan
    of distribution not previously disclosed in the Registration Statement or
    any material change to such information in the Registration Statement;

provided, however, that clauses (i) and (ii) do not apply if the information
required to be included in a post-effective amendment by those clauses is
contained in periodic reports filed with or furnished to the Commission by the
Company pursuant to Section 13 or 15(d) of the Exchange Act that are
incorporated by reference in the Registration Statement.

        (2) That, for the purpose of determining any liability under the
    Securities Act, each such post-effective amendment shall be deemed to be a
    new registration statement relating to the securities offered therein, and
    the offering of such securities at that time shall be deemed to be the
    initial bona fide offering thereof.

        (3) To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering.

                                       II-2



        (4) That, for purposes of determining any liability under the Securities
    Act, each filing of the Company's annual report pursuant to Section 13(a) or
    15(d) of the Exchange Act (and, where applicable, each filing of an employee
    benefit plans annual report pursuant to Section 15(d) of the Exchange Act)
    that is incorporated by reference in the Registration Statement shall be
    deemed to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof.

    B. Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Company pursuant to the provisions described above, or otherwise, the Company
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. If a claim for indemnification against such liabilities (other
than the payment by the Company of expenses incurred or paid by a director,
officer or controlling person of the Company 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 Company will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

                                       II-3


                                   SIGNATURES

         Pursuant to the requirements of the Securities Act of 1933, the
registrant certifies that it has reasonable grounds to believe that it meets all
