SUMMARY

        This summary highlights information from this prospectus. Because this is a summary, it may not contain all the information you should consider before investing in the securities we are offering. You should read this entire prospectus and any supplement carefully. You should also read the documents listed below in "Where You Can Find More Information" for information about us and our financial statements.

ALARIS Medical

        We develop and provide practical solutions for medication safety. We design, manufacture and market intravenous (IV) medication delivery and infusion therapy devices, needle-free disposables and related monitoring equipment in the United States and internationally. Our proprietary Guardrails Safety Software, our other "smart" technologies and our "smart" services help to reduce the risks and costs of medication errors, help to safeguard patients and clinicians and also gather and record clinical information for review, analysis and transcription. Our intravenous infusion systems are used to deliver to patients one or more fluids, primarily pharmaceuticals or nutritionals, and consist of medication safety systems, single and multi-channel large volume infusion pumps, syringe pumps and dedicated and non-dedicated disposable administration sets.

        ALARIS Medical was organized as a Delaware corporation on September 28, 1988. ALARIS Medical is a holding company for our operating subsidiary, ALARIS Medical Systems, Inc., which was formed by the merger of two pioneers in infusion systems, IMED Corporation (then an ALARIS Medical subsidiary) and IVAC Medical Systems, Inc., on November 26, 1996. Our headquarters are located at 10221 Wateridge Circle, San Diego, California 92121. Our telephone number is (858) 458-7000.

About this Prospectus

        This prospectus is part of a registration statement that we filed with the SEC using a "shelf" registration process. Under this shelf process, we may offer, from time to time, in one or more offerings:

        The total offering price of the securities that we may offer will not exceed $550,000,000. This prospectus provides you with a general description of the securities we may offer. Each time we offer securities, we will provide you with a prospectus supplement that will describe the specific amounts, prices and terms of the securities we offer. The prospectus supplement also may add, update or change information contained in this prospectus.

        We may sell securities to or through underwriters, dealers or agents or directly to purchasers. We reserve the sole right to accept and to reject in whole or in part any proposed purchase of securities. The prospectus supplement, which we will provide to you each time we offer securities, will provide the names of any underwriters, dealers or agents involved in the sale of securities, and any applicable fee, commission or discount arrangements with them. See "Plan of Distribution."

        Under the shelf registration process, the selling stockholders listed herein may sell up to a total of 450,000 shares of common stock under this prospectus. All of the selling stockholders are our executive officers, and the shares they may sell include shares currently owned by them and shares issuable upon exercise of vested stock options. Such sales by the selling stockholders would be made only through underwriters and only in connection with the exercise of any over-allotment option which may be granted to the underwriters. The number of shares of common stock to be offered by each of the selling stockholders is set forth in the section of this prospectus titled "Selling Stockholders." The aggregate number of shares to be offered by the selling stockholders represents 14% of the number of shares beneficially owned by the selling stockholders in the aggregate, as of March 8, 2003. Beneficial ownership includes shares which a selling stockholder may acquire upon exercise of stock options within 60 days after March 8, 2003. The aggregate number of shares to be offered by the selling stockholders also represents less than 10% of the aggregate number of shares they beneficially own plus shares issuable pursuant to stock options which first become exercisable after 60 days from March 8, 2003. We will not receive any of the proceeds from the sale of any shares of common stock by the selling stockholders other than proceeds we receive from the selling stockholders upon exercise of their stock options the underlying shares of which are covered by this prospectus.

Debt Securities

        We may offer both secured and unsecured general obligations of our company, which may be senior debt securities or subordinated debt securities. The senior debt securities will have the same rank as all our other unsubordinated debt. The subordinated debt securities will be entitled to payment only if all payments due under our senior indebtedness, including any outstanding senior debt securities, have been made.

        The debt securities will be issued under base indentures between us and The Bank of New York, as trustee, and supplemental indentures between us and the trustee or trustees we name in the prospectus supplement with respect to a particular series of debt securities. We have summarized certain general features of the debt securities from the indentures, which are or will be exhibits to the registration statement of which this prospectus is a part. We encourage you to read the base indentures and any supplemental indentures which would be filed as a part of a periodic or current report with the SEC. We provide directions on how to obtain copies of these reports under "Where You Can Find More Information."

Common Stock

        We may issue additional shares of our common stock, $.01 par value per share. Holders of common stock are entitled to one vote per share on all matters submitted to a vote of stockholders, except that such holders are entitled to vote their shares of common stock cumulatively in the election of directors. Holders of common stock are entitled to receive such dividends, if any, as may be declared by our board of directors, subject to the rights of preferred stockholders.

Preferred Stock and Depositary Shares

        We may issue our preferred stock, $.01 par value per share, in one or more series. Our board of directors will determine the dividend, voting, conversion and other rights of the series being offered and the terms and conditions of its offering and sale. We may also issue fractional shares of preferred stock that will be represented by depositary shares and depositary receipts.

Stock Purchase Units and Stock Purchase Contracts

        We may issue stock purchase units and stock purchase contracts, including contracts obligating holders to purchase from us, and obligating us to sell to those holders, a specified number of shares of common stock or preferred stock in the future. We may determine the price of shares of common stock or preferred stock at the time we issue the stock purchase contracts or the price may be determined by referring to a specific formula described in the stock purchase contracts. We may issue stock purchase contracts separately or as a part of stock purchase units consisting of a stock purchase contract and debt securities, preferred stock or debt obligations of third parties, including U.S. Treasury securities, which secure the holders' obligations to purchase the common stock or preferred stock under stock purchase contracts. Stock purchase contracts may require us to make periodic payments to the holders of the stock purchase units or vice versa. These payments may be unsecured or prefunded on some basis. Stock purchase contracts may require holders to secure their obligations in a specified manner.

Warrants

        We may issue warrants to purchase our debt securities, common stock or preferred stock. The applicable prospectus supplement will describe the details of the warrants.

RATIO OF EARNINGS TO FIXED CHARGES
(dollars in thousands)

        The following table sets forth our ratio of earnings to fixed charges for each of the last five years ended December 31 and the three months ended March 31, 2003. For purposes of computing the ratio of earnings to fixed charges, earnings represent earnings from continuing operations before income taxes adjusted for fixed charges. Fixed charges include interest on all indebtedness (including interest expense from discontinued operations), estimated interest component of rental expense, capitalized interest for the period and amortization of deferred financing costs.

USE OF PROCEEDS

        We expect to use the net proceeds from our sale of the securities to reduce, repurchase or refinance some or all of the following indebtedness:

        and to pay the expenses we incur in connection with such transactions. We will use any proceeds which we do not use for the reduction, repurchase or refinancing of this indebtedness for general corporate purposes. We will not receive any of the proceeds from the sale of any shares of common stock by the selling stockholders other than proceeds we receive from the selling stockholders upon exercise of their stock options the underlying shares of which are covered by this prospectus.

RISK FACTORS

        Investing in our securities will be subject to risks, including risks inherent in our business. The value of your investment may decline and could result in a loss. You should carefully consider the following risk factors and the other information contained and incorporated by reference in this prospectus and any prospectus supplement before investing in our securities.

        Our substantial level of indebtedness could have a material adverse effect on our financial condition.

        We have a substantial amount of indebtedness. At March 31, 2003, we had $508.2 million combined outstanding indebtedness composed of obligations of ALARIS Medical and ALARIS Medical Systems. ALARIS Medical's indebtedness consisted of $158.2 million of senior discount notes. ALARIS Medical Systems' indebtedness consisted of $170.0 million of senior secured notes and $180.0 million of senior subordinated notes. Although we intend to use some or all of the net proceeds of the offering of the securities covered by this prospectus and any prospectus supplements to reduce, repurchase or refinance some or all of such outstanding indebtedness, we expect that we will continue to have substantial indebtedness even after any such refinancing.

        Our high level of indebtedness could have important consequences, including the following:

        We expect to continue to meet our short-term liquidity needs, including capital expenditure requirements, with cash flow from operations of ALARIS Medical Systems and cash on hand. We will continue to use our funds primarily for operating expenses, including planned expenditures for new research and development programs, capital expenditures and scheduled interest payments on outstanding indebtedness. Additionally, we may use a portion of our funds to purchase some of our long-term debt from time to time in open market or privately negotiated transactions to the extent that the indentures covering such indebtedness permit us to do so. If we do not refinance all, or a substantial portion, of our existing indebtedness with the proceeds of this offering, we will be required to refinance some of that indebtedness prior to December 2006 since management believes that it is unlikely that ALARIS Medical Systems will generate sufficient cash flow from operations to repay the remaining senior secured notes and senior subordinated notes at maturity in 2006 and to permit it to make distributions to ALARIS Medical to enable it to repay the senior discount notes at maturity in 2008. Such refinancing may involve an offering of debt securities of ALARIS Medical Systems or ALARIS Medical (or both), an offering of equity securities of ALARIS Medical to reduce the level of indebtedness of ALARIS Medical Systems or ALARIS Medical (or both), or a combination of any of the foregoing. Such offering may include an offering of the securities covered by this prospectus and any prospectus supplement. The ability of ALARIS Medical Systems or ALARIS Medical, or both, to obtain such debt or equity financing will be dependent upon many factors, including overall financial market and economic conditions and our operating performance and expectations at such time.

        Should ALARIS Medical Systems not repay its indebtedness at maturity in 2006, should ALARIS Medical not repay the senior discount notes in 2008, or should ALARIS Medical Systems not be able to continue to make distributions to ALARIS Medical in order to permit ALARIS Medical to make cash interest payments on the senior discount notes, these events could have a material adverse effect

6



on our business, financial condition and results of operations and could result in a default by ALARIS Medical, ALARIS Medical Systems or both, and possible acceleration of all or a portion of such indebtedness, unless ALARIS Medical, ALARIS Medical Systems or both could refinance such indebtedness or obtain the required funds from other sources.

        Debt securities will be our obligations exclusively, and so long as we conduct our operations exclusively through subsidiaries, our cash flow and our ability to service debt will be primarily dependent upon the earnings of our subsidiaries.

        We currently conduct all of our operations through our wholly-owned subsidiary, ALARIS Medical Systems, and its subsidiaries. So long as we do so, our cash flow and our ability to service debt, including the debt securities offered by the applicable prospectus supplement, will be primarily dependent upon the earnings of those subsidiaries and the distribution of those earnings to us, or upon loans or other payments of funds by those subsidiaries to us. Our subsidiaries are separate and distinct legal entities and have no obligation to pay any amounts due pursuant to the debt securities or to make any funds available to us to repay our obligations, whether by dividends, loans or other payments. None of our subsidiaries will guaranty any of our obligations under the debt securities. In addition, the payment of dividends and the making of loans and advances to us by our subsidiaries may be subject to statutory or contractual restrictions, are contingent upon the earnings of those subsidiaries and are subject to various business considerations.

        The success of our business strategy depends in part upon market acceptance of our newest product and service offerings, which focus on delivering practical solutions for medication safety, and our ability to maintain our technological leadership position in the medication safety area through the development of new products and services.

        In response to the recent emergence of patient safety as an important health care issue, and as a result of the maturation and increasing competitiveness of the markets for traditional infusion pumps and patient monitoring devices, we have increasingly focused our business strategy on developing products and services which are designed to reduce medication errors. In the fourth quarter of 2001, we introduced our Medley Medication Safety System with our Guardrails Safety Software and, in third quarter of 2002, we introduced our Guardrails Safety Software for our Signature Edition large volume pump and our Guardrails Continuous Quality Improvement (CQI) Event Tracker System. We have made and will continue to make significant investments in the development of our products and services, but we cannot assure you that the demand for our new products and services will justify such investments or that they will achieve widespread market acceptance. We may also be required to devote substantial resources to upgrading and enhancing our existing products and services after market introduction. We cannot assure you that in the future we will successfully complete or market new products or services, or enhancements to existing ones.

        Although our Medley Medication Safety System was the first infusion system of its kind approved for use in the United States, and we know of no other systems currently being marketed which provides as comprehensive a solution to the problem of medication safety as our Medley and Guardrails Safety Systems, we cannot assure you that we can maintain our technological leadership in the area of medication safety. Maintaining our technological leadership will be important to the success of our products and services, as will our ability to be responsive to pricing pressures and changing business models. If competitors introduce products, services or technologies that are better than ours or that gain greater market acceptance, or if new industry standards emerge, our business, results of operations and financial condition could be materially and adversely affected. Our competitors may succeed in developing medication safety products and services which may achieve equal or greater market acceptance than ours, which would create pricing pressure on our medication safety products and services. Additionally, if we do not successfully reposition our older products for sale to different markets, our introduction of new products and services will reduce sales of such older products.

7



        Furthermore, a hospital's decision to purchase our Medley Medication Safety System is a significant business decision which is made with great care. The costs and time commitments involved in negotiating purchasing contracts for our Medley Medication Safety System and its component products and services may adversely affect our ability to consummate these sales or to consummate them in a timely manner. Failure to complete these sales could adversely affect our business, results of operations or financial condition. In addition, delays in completing such contracts could create variability in our operating results from period to period, which could cause fluctuations in the trading prices of our shares.

        We face substantial competition in all of our markets.

        Our major competitors are Baxter International, Inc., Abbott Laboratories, Inc. and B. Braun Medical, Inc. in the United States market and Graseby Medical Limited, Fresenius Medical Care AG and B. Braun Melsungen AG in the international market. These companies have greater financial, research and development and marketing resources than we have. Our U.S. competitors are able to offer volume discounts based on bundled purchases of a broader range of medical equipment, pharmaceuticals and supplies than we sell, including infusion systems and intravenous solutions used with such systems. We cannot assure you that such competition will not have a material adverse effect on our business, financial condition, results of operations or cash flows.

        The primary markets for many of our current products are relatively mature and highly competitive. We believe our success is dependent on the development of new infusion technologies and products, new product categories and the development of other markets for our products. Our older infusion therapy product lines have experienced flat or declining sales and market share in some geographic areas recently, primarily due to competitors who offer volume discounts based on bundled purchases of a broader range of medical equipment and supplies, as well as to the aging of these products. We intend to continue to introduce new products in order to offset future declines in sales and market share of the mature segment of our current product line. We cannot assure you that new products will be successfully completed or marketed for sale, will not necessitate upgrades or technical adjustments after market introduction, can be manufactured in sufficient volumes to satisfy demand, or will fully offset declines in sales and market share experienced with respect to existing products.

        There is a concentration of buying power among our U.S. customers, which may increase competition for sales and put downward pressure on pricing.

        Most sales in the U.S. hospital market are made to individual hospitals through long-term contracts with group purchasing organizations, or GPOs, which aggregate the buying power of their member hospitals and monitor compliance with purchase commitments and, generally, charge an administrative fee to product providers for such services. GPOs often enter into exclusive purchase commitments with as few as one or two providers of infusion systems and/or patient monitoring products for a period of several years. If we are not one of the selected providers, we may be precluded from making sales to members of a GPO for several years and, in certain situations, the GPO may require removal of our existing installed infusion pumps, which would result in a loss of the related disposable administration set sales. Even if we are one of the selected providers, we may be at a disadvantage relative to other selected providers which are able to offer volume discounts based on bundled purchases of a broader range of medical equipment and supplies. Further, we may be required to commit to pricing which has an adverse impact on our profit margins.

        Our inability to protect our intellectual property positions could have a material adverse effect on our performance.

        We rely heavily on patents and other proprietary technology. Our inability to protect these positions could have a material adverse effect on our business, financial condition, results of operations

8



or prospects. We cannot assure you that patent applications we submit will result in patents being issued or that, if issued, such patents will afford protection against competitors with similar technology.

        Legal standards relating to the scope of claims are still evolving in the courts and we cannot guarantee that our patents will be upheld as valid and enforceable. The U.S. Patent and Trademark Office may later modify or revoke our issued patents. This may create an extended period of uncertainty until the matter is resolved, which could take several years or more. In addition, foreign patents may be more difficult to obtain, more difficult to protect and the remedies that are available against infringers may be less extensive than in the United States.

        Because U.S. patent applications are maintained in secrecy for at least the first eighteen months after filing and because publication of discoveries in the scientific or patent literature tends to lag behind actual discoveries, we cannot be certain that we were the first creator of the inventions covered by pending patent applications or the first to file patent applications on such inventions. We cannot assure you that any of our pending patent applications will be allowed, or if allowed, that the scope of the claims allowed will be sufficient to protect our products. Without establishing this priority, we will be unable to patent our inventions and, in fact, a patent on the invention may be awarded to another party. Interference or opposition proceedings instituted against us may increase the costs associated with the patent application process, delay the issuance of patents, or both.

        In addition, we cannot assure you that any of our patents or licensed patents will not be infringed or designed around by others, that others will not obtain patents that we will need to license or design around, that our products will not inadvertently infringe the patents of others, or that others will not manufacture and distribute similar products upon expiration of such patents. We cannot assure you that our patents will not be invalidated or that we or our licensors will have adequate funds to finance the high cost of prosecuting or defending patent validity or infringement issues.

        We sell our products under a variety of trademarks, some of which we consider to be of sufficient importance to register in the United States and various foreign countries in which we do business. We also rely on trade secrets, unpatented know-how and continuing technological advancement to maintain our competitive position. It is our practice to enter into confidentiality agreements with certain technical employees and consultants.

        The legal protections afforded by trade secret, patent, copyright and trademark laws, nondisclosure and other contractual provisions and technical measures provide only limited protection for our products and services. Monitoring unauthorized use of our products and services is difficult and we cannot assure you that these measures will prevent the unauthorized disclosure or use of our trade secrets and know-how or that others may not independently develop similar trade secrets or know-how or obtain access to our trade secrets, know-how or proprietary technology, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States.

        Non-compliance with government regulation could seriously harm our business.

        We are subject to extensive governmental regulation, and our failure to comply with these regulations can have serious consequences upon our business. Government regulation is a significant factor in the research, development, testing, production and marketing of our products. If we do not comply with applicable regulatory requirements, we may need to recall products or suspend production of them. In addition, government regulators may refuse to allow the clinical testing or commercial distribution of our products and we could face civil sanctions or criminal prosecution. We cannot assure you that our existing products will consistently comply with such regulations or that any new products we develop will receive any necessary government approvals.

        Our products are regulated as medical devices. Medical devices are regulated by a variety of governmental agencies, including those of the United States, the individual states and those of other countries. In the United States, the Federal Food, Drug, and Cosmetic Act, or FDC Act, authorizes the

9


U.S. Food and Drug Administration, or FDA, to regulate the introduction of medical devices into commerce. FDA requires us to register with it and to list our devices. FDA has the authority to regulate the manufacturing, labeling, adverse event reporting, exporting and promotion, as well as related record keeping, for such products. FDA's enforcement of the FDC Act depends to a great extent on the agency's interpretation of the FDC Act and regulations promulgated thereunder. We cannot assure you that FDA's interpretations will not have a material adverse effect on our business, financial condition, results of operations or prospects.

        Obtaining necessary new product clearances or approvals from FDA is important to our business and can be a time consuming and expensive process. We cannot assure you that such clearances or approvals will be granted or that FDA's review of submissions or applications for the same will not involve delays adversely affecting the marketing and sale of our products. We face comparable regulatory risks in the various countries in which we sell our products.

        Certain states require licensing of medical device manufacturing facilities. Our manufacturing facility located in the State of California has such a requirement. We currently have a California Medical Device Manufacturing license for our facility in California. This license must be renewed annually. In order to retain this license, our facility in California must be in compliance with the FDC Act and the applicable state laws.

        We also have manufacturing facilities in the United Kingdom and Mexico which must meet the regulatory requirements imposed by those countries. Countries in the European Union, and other countries, are in the process of developing new approaches for regulating medical products which may result in lengthening the time required or changing the requirements to obtain permission to market new devices. These changes could have a material adverse effect on our ability to market our devices in such countries and could hinder or delay the successful implementation of our planned international expansion.

        Recent and future federal and state regulations in the U.S. relating to patient privacy could impose burdens on us.

        Federal and state laws regulate the confidentiality of certain patient health information, including patient records, and the use and disclosure of that "protected health information." In particular, in December 2000, the U.S. Department of Health and Human Services (HHS) published patient privacy rules under the Health Insurance Portability and Accountability Act of 1996 (HIPAA privacy rule) and, in August 2002, published final modifications to the HIPAA privacy rule. The HIPAA privacy rule applies only to health plans, health care clearinghouses and certain health care providers. However, the HIPAA privacy rule also conditions the disclosure of protected health information from health care providers to third parties, or "business associates," who perform services for the health care provider involving the use of protected health information.

        The patient data that we access, collect and analyze in the future may include protected health information. If so, we would then need to comply with certain regulations under the HIPAA privacy rule as a "business associate" of those healthcare providers and would face increased obligations regarding any protected health information we would receive on behalf of those providers. Those obligations would include agreeing, typically by contract, to use that protected health information only for certain purposes, to safeguard that information from misuse and to help those providers comply with their duties to provide patients with access to their health information.

        In addition, many states also regulate the privacy of health information and it is unclear how the HIPAA privacy rule will interact with existing or emerging state law. Further, in February 2003, HHS issued regulations governing the security of protected health information, which imposes detailed requirements on business associates relating to the storage, use and transmission of health information (HIPAA security rule). We are evaluating the applicability of the HIPAA privacy rule and the HIPAA

10



security rule to our existing and new products and services and our compliance obligations. If we need to comply with the HIPAA privacy rule, the HIPAA security rule, or both, in the future, additional compliance resources may be required.

        Governmental initiatives to contain healthcare costs could adversely affect our profit margins.

        There have been a number of governmental initiatives to reduce healthcare costs. In the U.S., for example, Congress and various state legislatures periodically propose changes in law and regulation that could have a major impact on the healthcare industry. Changes in governmental support of healthcare services, the prices for such services, mandates for particular features or functionalities or the regulations governing such services, as well as the growth of managed care organizations may all have a material adverse effect on our business, financial condition, results of operations or prospects. The costs of complying with possible new requirements may have a negative impact on our future earnings or on our customers' ability or willingness to purchase our products. In addition, we may find limited demand for new medical devices until reimbursement approval has been obtained from governmental and third-party payors.

        Other governmental initiatives to contain healthcare costs focus on improving patient safety through the use of technologically advanced products and services. The success of our business strategy depends in part upon a continued emphasis by the government, as well as insurance companies, the public and the media, on patient safety, reducing the incidence of adverse drug events, or ADEs, enhancing patient care and improving medical outcomes, through the kind of products and services we offer or will offer in the future. If these concerns become less of a priority, it could adversely affect our business strategy.

        We could face potential product liability claims relating to the use of our products.

        We face an inherent business risk of exposure to product liability claims in the event that the use of our products is alleged to have resulted in death, injury or other adverse effects. Products as complex as ours sometimes are alleged to contain errors, particularly in software components, that remain undetected, despite rigorous testing, until used in a variety of situations by many customers under varying circumstances. Such errors can result in expensive product recalls, product liability claims or warranty expenditures. There can be no assurance that we will not be subject to any such expenses or product liability claims, that such claims will not result in liability in excess of any applicable insurance coverage or that our insurance will cover any expenses or claims made. We currently maintain product liability insurance coverage but we cannot assure you that we will be able to obtain such insurance on acceptable terms in the future, if at all, or that any such insurance will provide adequate coverage against potential claims. Our insurance excludes coverage for punitive damages. Product liability claims can be expensive to defend and can divert management and other personnel for months or years regardless of the ultimate outcome. An unsuccessful product liability defense could have a material adverse effect on our business, financial condition, results of operations or prospects.

        Our software products could result in unforeseen liabilities.

        Our medication safety software is very complex. As with many complex software products, our systems may contain errors, especially when first introduced. Our recent product offerings, including our Medley Medication Safety System, our Guardrails Safety Software and our Guardrails CQI Event Tracker System, are intended to assist healthcare providers who are providing patient care. Therefore, users of our products likely have a greater sensitivity to system errors than users of software products generally. Failure of our software products to perform in accordance with our documentation could constitute a breach of warranty and could subject us to significant liability.

11



        We are controlled by our principal stockholder.

        One stockholder, Jeffry M. Picower, beneficially owns more than 50% of our common stock and has the power to determine the outcome of any action requiring the approval or consent of the holders of our common stock, including the election of our directors.

        We are subject to certain risks associated with our foreign operations.

        A substantial portion of our sales and earnings are attributable to international sales and manufacturing operations. During the years ended December 31, 2002 and 2001, $148.9 million and $140.1 million, respectively, of our sales were generated internationally, representing approximately 32% and 34% of our total sales during the respective periods. The value of our non-U.S. denominated sales and earnings is impacted by currency exchange rate fluctuations. Changes in currency exchange rates could have a material adverse effect on our business, financial condition, results of operations or prospects. Furthermore, international manufacturing and sales are subject to other inherent risks.

        We are subject to certain risks globally.

        Our operations are subject to special risks that can materially affect our sales, profits and cash flows, including, among other risks, the following:

        Supply risks and shortages could harm our business.

        We purchase a significant amount of the raw materials we need by purchase order, and have, on occasion, experienced temporary delays due to supplier shortages. In addition, we rely on a limited number of suppliers for circuit boards and other parts which are used in certain of our infusion systems. The loss of any of these suppliers would temporarily disrupt or interrupt our manufacturing process and could affect our ability to manufacture in sufficient volumes to satisfy demand. Such disruption could materially and adversely affect our business, results of operations and financial condition.

        We may be adversely affected by environmental and safety regulations to which we are subject.

        We must comply with environmental laws and regulations concerning emissions to air, waste water discharges and the generation, handling, storage, transportation and disposal of hazardous wastes in the United States and other countries in which we do business. We believe that we possess all material permits and licenses necessary for the continuing operation of our business and that our operations are in substantial compliance with the terms of all applicable environmental laws. We cannot assure you that we will operate at all times in complete compliance with all such requirements. We cannot assure

12



you that the applicable regulatory body's interpretation will not have a material adverse effect on our business, financial condition, results of operations or prospects. We could be subject to potentially significant civil or criminal fines and penalties for any noncompliance that may occur. It is impossible to predict accurately what effect these laws and regulations may have on us in the future.

        There are substantial risks associated with investing in our common stock.

        Our stock price has been and likely will continue to be volatile, and we cannot assure you that your initial investment in our common stock will not fluctuate significantly. This volatility depends upon many factors, many of which are beyond our control, including:

        Future sale of our common stock in the public market could lower the stock price.

        We may, in the future, sell additional shares of our common stock in subsequent public offerings. Additionally, a substantial number of shares of our common stock is available for future sale pursuant to stock options that we have granted to our employees and to our non-employee directors to purchase shares of our common stock. We cannot predict the effect, if any, that future sales of our common stock will have on the market price of our common stock. Future sales of substantial amounts of our common stock (including shares issued upon the exercise of stock options), or the perception that such sales could occur, may adversely affect prevailing market price for our common stock.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

        Some things in this prospectus or any prospectus supplement, or incorporated by reference in this prospectus or any prospectus supplement, are known as "forward-looking statements," as that term is used in Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Certain of these forward-looking statements can be identified by the use of forward-looking terminology such as "believes," "expects," "may," "will," "should," "seeks," "approximately," "intends," "plans," "estimates" or "anticipates" or the negative of these terms or other comparable terminology, or by discussions of strategy, plans or intentions. Statements contained in this prospectus or any prospectus supplement that are not historical facts are forward-looking statements. Without limiting the generality of the preceding statement, all statements in this prospectus or any prospectus supplement concerning or relating to estimated and projected earnings, margins, costs, expenditures, cash flows, growth rates and financial results are forward-looking statements. In addition, through our senior management, from time to time we make forward-looking statements concerning our expected future operations and performance and other developments. Such forward-looking statements are necessarily estimates reflecting our best judgment based upon current information and involve a number of risks and uncertainties. Other factors may affect the accuracy of these forward-looking statements and our actual results may differ materially from the results anticipated in these forward-looking statements. While it is impossible to identify all such factors, factors that could cause actual results to differ materially from those estimated by us include, but are not limited to, those factors or conditions described under "Risk Factors."


GENERAL DESCRIPTION OF SECURITIES

        We may offer debt securities, shares of common stock, shares of preferred stock, depositary shares, stock purchase units, stock purchase contracts or warrants to purchase debt securities, common stock or preferred stock, or any combination of the foregoing, either individually or as units consisting of one or more securities. We may offer up to $550,000,000 of securities under this prospectus. In addition, the selling stockholders may offer up to 450,000 shares of our common sock, as described under "Selling Stockholders." If securities are offered as units, we will describe the terms of the units in a prospectus supplement.


DESCRIPTION OF DEBT SECURITIES

        We may issue senior debt securities and subordinated debt securities from time to time in one or more series. The senior debt securities and subordinated debt securities will be issued under and controlled by separate indentures between us, as issuer, and The Bank of New York, as trustee, which we refer to as the indentures, and any applicable supplements to the indentures. A copy of each type of indenture is filed as an exhibit to the registration statement of which this prospectus is a part. If we enter into any indenture supplement, we will file a copy of that supplement with the SEC.

        The following is a summary of certain general terms and provisions of the indentures and is not complete. The particular terms of any series of debt securities we offer, including the extent to which the general terms and provisions may apply to that series of debt securities, may be described in a prospectus supplement relating to those debt securities. You should read the indentures and any supplements in their entirety.

General Terms

        The debt securities represent our direct, general secured or unsecured obligations and:

14


        The applicable prospectus supplement will describe the debt securities and the price or prices at which we will offer the debt securities. The description will include:

15


16



        The debt securities may be issued in whole or in part in the form of one or more global securities and as book-entry securities that will be deposited with, or on behalf of, a depositary named by us and identified in a prospectus supplement with respect to such series. The prospectus supplement will specify whether the offered debt securities will be in registered, bearer, global or book-entry form.

Global Securities

        We may issue debt securities of a series in whole or in part in the form of one or more global debt securities. A global security is a security, typically held by a depositary, which represents and is denominated in an amount equal to the aggregate principal amount of all outstanding debt securities of a series or any portion thereof, in either case having the same terms, including the same original issue date, date or dates on which principal and interest are due, and interest rate or method of determining interest and which bears a legend placed on all global securities issued under the indenture. Any global debt securities will be deposited with, or on behalf of, a depositary or its nominee, which will be identified in the applicable prospectus supplement. We may issue global securities in either registered or bearer form and in either temporary or definitive form.

        Unless and until a global security is exchanged in whole or in part for the individual debt securities represented thereby, a global security may not be transferred except as a whole:

        The prospectus supplement relating to a particular series of debt securities will describe the specific terms of the depositary arrangement with respect to such series of debt securities. We anticipate that the following provisions will generally apply to all depositary arrangements for debt securities:

17


        The laws of some states may require that specified purchasers of securities take physical delivery of the securities in definitive form. These laws may limit the ability of those persons to own, transfer or pledge beneficial interests in global securities.

        So long as the depositary for a global security, or its nominee, is the registered owner of the global security, the depositary or its nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by the global security for all purposes under the indenture. Except as stated below, owners of beneficial interests in a global security:

        Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for the registered global security and, if the person is not a participant, on the procedures of the participant through which the person owns its interests, to exercise any rights of a holder under the indenture applicable to the registered global security.

        We understand, however, that under existing industry practices, if we request any action of holders, or if an owner of a beneficial interest in a registered global security desires to give or take any action which a holder is entitled to give or take under the indenture, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take the action, and the participants would authorize beneficial owners owning through the participants to give or take the action or would otherwise act upon the instructions of beneficial owners holding through them.

        Subject to the restrictions applicable to bearer securities described in the applicable prospectus supplement, principal premium, if any, and interest payments on individual debt securities represented by a global security will be made to the depositary or its nominee, as the case may be, as the registered owner or holder of such global security. Neither we, the applicable trustee, nor any registrar or paying agent of the debt securities will be responsible or liable for any aspect of the records relating to, or payments made on account of, beneficial ownership interests in the global security for the series or for maintaining, supervising or reviewing any records relating to the beneficial ownership interests.

        We expect that the depositary for any such debt securities represented by a global security, upon receipt of any payment of principal, premium, if any, or interest in respect of the global security, will

18



immediately credit participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the global security as shown on the depositary's records. We also expect that payments by participants to owners of beneficial interests in a global security held through the participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers and registered in "street name." Such payments will be the responsibility of the participants. Receipt by owners of beneficial interests in a temporary global security of payments of principal, premium or interest with respect thereto will be subject to the restrictions described in an applicable prospectus supplement.

        If the depositary for any debt securities represented by a global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Securities Exchange Act of 1934, we will appoint an eligible successor depositary. If we fail to appoint an eligible successor depositary within 90 days, individual debt securities of such series will be issued in exchange for the global security. In addition, we may at any time and in our sole discretion determine not to have any debt securities of a series represented by one or more global securities. In that event, individual debt securities of such series will be issued in exchange for the global security representing such series debt securities. Furthermore, if we so specify with respect to the debt securities of a series, an owner of a beneficial interest in a global security representing debt securities of such series may, on terms acceptable to us, the trustee, and the depositary for such global security, receive individual debt securities of such series in exchange for such beneficial interests, subject to any limitations described in the prospectus supplement relating to such debt securities. In any such instance, an owner of a beneficial interest in a global security will be entitled to physical delivery of individual debt securities of the series represented by such global security equal in principal amount to such beneficial interest and to have such debt securities registered in its name (if the debt securities are issuable as registered securities). Individual debt securities of such series so issued will be issued (a) as registered securities in denominations, unless otherwise specified by us, of $1,000 and integral multiples thereof if the debt securities are issuable as registered securities, (b) as bearer securities in the denomination or denominations specified by us if the debt securities are issuable as bearer securities or (c) as either registered securities or bearer securities as described above if the debt securities are issuable in either form.

Limitations On Issuance Of Bearer Securities

        The debt securities of a series may be issued as registered securities (which will be registered as to principal and interest in the register maintained by the registrar for such debt securities) or bearer securities (which will be transferable only by delivery). If such debt securities are issuable as bearer securities, the applicable prospectus supplement will describe certain special limitations and considerations that will apply to such debt securities.

Covenants

        If debt securities are issued, the indenture, as supplemented for a particular series of debt securities, will contain certain covenants for the benefit of the holders of such series of debt securities, which will be applicable (unless waived or amended) so long as any of the debt securities of such series are outstanding, unless stated otherwise in the prospectus supplement. The specific terms of the covenants, and summaries thereof, will be set forth in the prospectus supplement relating to such series of debt securities.

Effective Subordination

        Any debt securities we issue will be our obligations exclusively. If we continue to conduct our operations through our subsidiaries, our cash flow and our ability to service debt, including the debt securities offered through the applicable prospectus supplement, will be primarily dependent upon the

19



earnings of our subsidiaries and the distribution of those earnings to us or upon loans or other payments of funds by those subsidiaries to us. Our subsidiaries are separate and distinct legal entities and have no obligation to pay any amounts due pursuant to any debt securities issued by us or to make any funds available to us to repay our obligations, 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 or contractual restrictions, are contingent upon the earnings of those subsidiaries and are subject to various business considerations.

        Any right of ours to receive assets of any of our subsidiaries upon their liquidation or reorganization and therefore the right of the holders of our debt securities to participate in those assets will be effectively subordinated to the claims of that subsidiary's creditors, including trade creditors.

Subordination of Subordinated Debt Securities

        Unless the prospectus supplement indicates otherwise, the following provisions will apply to the subordinated debt securities. In addition to the effective subordination described above in "—Effective Subordination," to the extent we issue subordinated debt securities, they will also be contractually subordinated to any senior debt securities or other senior indebtedness that we may issue. The indebtedness underlying the subordinated debt securities will be payable only if all payments due under our senior indebtedness, including any outstanding senior debt securities, have been made. If we distribute our assets to creditors upon any dissolution, winding-up, liquidation or reorganization or in bankruptcy, insolvency, receivership or similar proceedings, we must first pay all amounts due or to become due on all senior indebtedness before we pay the principal of, or any premium or interest on, the subordinated debt securities. In the event the subordinated debt securities are accelerated because of an event of default, we may not make any payment on the subordinated debt securities until either we have paid all senior indebtedness or the acceleration is rescinded.

        If we experience a bankruptcy, dissolution or reorganization, holders of senior indebtedness may receive more, ratably, and holders of subordinated debt securities may receive less, ratably, than our other creditors.

Payment and Paying Agents

        Unless the prospectus supplement indicates otherwise, we will pay principal and any premium or interest on a debt security to the person in whose name the debt security is registered at the close of business on the regular record date for such interest.

        Unless the prospectus supplement indicates otherwise, we will pay principal and any premium or interest on the debt securities at the office of our designated paying agent, except that we may pay interest by check mailed to the address of the person entitled to the payment. Unless the prospectus supplement indicates otherwise, the corporate trust office of the trustee will be the paying agent for the debt securities.

        Any other paying agents we designate for the debt securities of a particular series will be named in the prospectus supplement. We may designate additional paying agents, rescind the designation of any paying agent or approve a change in the office through which any paying agent acts, but we must maintain a paying agent in each place of payment for the debt securities.

        The paying agent will return to us all money we pay to it, in trust, for the payment of the principal of, premium, if any, or interest on any debt security that remains unclaimed for a specified period. Thereafter, the holder may look only to us for payment.

20



Consolidation, Merger and Sale of Assets

        The indentures provide that, unless the prospectus supplement indicates otherwise, we may not consolidate with or merge into any other person or convey, transfer or lease substantially all of our properties and assets to another person, unless, among other things:

        Notwithstanding the above conditions, the indentures do not prohibit a consolidation or merger between us and a wholly-owned subsidiary, the transfer of all or substantially all of our properties or assets to a wholly-owned subsidiary or the transfer of all or substantially all of the properties or assets of a wholly-owned subsidiary to us, provided that if we are not the surviving entity of such a transaction or we are not the person to which such transfer is made, then the surviving entity or the person to which such transfer is made must expressly assume, by supplemental indenture, all our obligations under the debt securities and the indentures.

Events of Default

        Each of the following constitutes an event of default under the forms of indenture with respect to any series of debt securities which may be issued:

21


A supplemental indenture may omit, modify or add to the foregoing events of default which will be described in the prospectus supplement.

        If an event of default (other than an event of default under the provisions described in the fifth clause above) occurs and continues, either the trustee or the holders of at least 25% in aggregate principal amount of the outstanding applicable series of debt securities may declare the unpaid principal of, premium, if any, and accrued but unpaid interest on all the applicable debt securities of that series to be due and payable. Upon such a declaration, such principal of (or, in the case of original issue discount debt securities, the portion thereby specified in the terms thereof), premium, if any, and accrued interest shall be due and payable immediately. If an event of default occurs under the provisions described in the fifth clause above, the principal of (or, in the case of original issue discount debt securities, the portion thereby specified in the terms thereof), premium, if any, and accrued interest on all the applicable debt securities will automatically become immediately due and payable without any declaration or other act on the part of the trustee or any holders of such debt securities.

        In case an event of default occurs and is continuing, the trustee is under no obligation to exercise any of the rights or powers of the trustee under the applicable indenture at the request or direction of any of the holders of the applicable debt securities, unless such holders have offered to the trustee reasonable security or indemnity, satisfactory to it, against any associated cost, expense or liability. Except to enforce the right to receive payment of principal, premium, if any, or interest when due, no holder of a debt security may pursue any remedy with respect to the applicable indenture or debt securities unless:

        The holders of a majority in principal amount of the outstanding debt securities of such series are given the right under the indentures to direct the time and method of, and the place of conducting, any proceeding for exercising any remedy available to the trustee or of exercising any trust or power conferred on the trustee with respect to that series. The trustee, however, may refuse to follow any direction that conflicts with law or the applicable indenture or, subject to the duties of the trustee as stated in the indenture, that the trustee determines may be prejudicial to the rights of any other holder of such series of debt securities or that may involve the trustee in personal liability.

        If a default with respect to a series of debt securities occurs, is continuing and is known to the trustee, such trustee must mail to each holder of such debt securities notice of the default within 90 days after it occurs. Except in the case of a default in the payment of principal, premium, if any, or interest on any debt security, the trustee may withhold notice if and for so long as a committee of its trust officers in good faith determines that withholding notice is in the interests of the holders of the debt securities. In addition, we are required to deliver to each trustee, within 120 days after the end of each fiscal year, an officers' certificate indicating whether the signers thereof know of any default under the related indenture that occurred during the previous year.

22



Modification of the Indentures

        We and the trustee may amend or supplement the indentures without the consent of any holder of debt securities for one or more of the following purposes:

23


        We and the trustee may amend or supplement the indenture or the debt securities of any series with the consent of the holders of at least a majority in principal amount of the debt securities of each series then outstanding voting as a single class, and any existing default or event of default or compliance with any provision of the indenture or debt securities of any series may be waived with the consent of the holders of a majority in principal amount of the then outstanding debt securities of each series voting as a single class. However, without the consent of all of the holders of the debt securities so affected, no such amendment, supplement or waiver shall:


Defeasance

        The indentures provide that we shall have, at our option:

24


        If we exercise our legal defeasance option with respect to a series of debt securities, payment of such debt securities may not be accelerated because of an event of default. If we exercise our covenant defeasance option with respect to a series of debt securities, payment of such debt securities may not be accelerated because of an event of default related to the specified covenants.

        The applicable prospectus supplement will describe the procedures we must follow in order to exercise our defeasance options.

Regarding The Trustee

        The forms of indenture provide that, except during the continuance of an event of default, the trustee will perform only such duties as are specifically set forth in the indenture. During the existence of an event of default, the trustee will exercise its rights and powers under the indenture and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs.

        We and the trustee may have had, and continue to have, other customary banking agreements and arrangements, including stock transfer agent, lending and depository relationships.

        The forms of indenture and provisions of the Trust Indenture Act of 1939 that are incorporated by reference therein contain limitations on the rights of the trustee, should it become one of our creditors, to obtain payment of claims in certain cases or to realize on certain property received by it in respect of any such claim as security or otherwise. The trustee is permitted to engage in other transactions with us or any of our affiliates; provided, however, that if it acquires any conflicting interest (as defined under the Trust Indenture Act), it must eliminate such conflict or resign.

Governing Law

        The indentures and the debt securities will be governed by and construed in accordance with the laws of the state of New York.

25



DESCRIPTION OF COMMON STOCK

General

        Under our restated certificate of incorporation, we may issue up to 85,000,000 shares of our common stock, $.01 par value per share. Our common stock is listed for trading on the American Stock Exchange under the trading symbol "AMI". As of April 11, 2003, there were 60,003,363 shares of common stock outstanding.

        Holders of our common stock are entitled to one vote per share on all matters submitted to a vote of stockholders, except that holders of our common stock are entitled to vote their shares cumulatively in the election of directors. Subject to the rights of the holders of outstanding shares of our preferred stock, if any, the holders of our common stock are entitled to such dividends, if any, as may be declared from time to time by our board of directors. If we are liquidated, dissolved or wound up, we must first pay all amounts we owe our creditors and then pay the full amounts required to be paid to holders of outstanding shares of our preferred stock, if any, before we may make any payments to holders of shares of our common stock. All holders of shares of our common stock are entitled to share ratably in any assets available for distribution to them, after all of our creditors have been satisfied and we have paid the liquidation preferences of any of our preferred stock. Holders of common stock have no preemptive rights or rights to convert their common stock into any other securities. Our common stock is neither redeemable nor subject to call. No sinking fund provisions apply to our common stock. All outstanding shares of common stock are fully paid and nonassessable.

Limitation of Liability and Indemnification

        Our restated certificate of incorporation contains a provision eliminating the liability of our directors for monetary damages for breach of fiduciary duty as a director, except if required by the Delaware General Corporation Law, or DGCL, in effect at the time the breach giving rise to the claim of liability was committed or omitted, as the case may be, for liability:

        In addition, our bylaws provide for indemnity, to the fullest extent permitted by the DGCL, for any expense, liability and loss reasonably incurred by any of our past or present directors or officers (or any past or present director, officer, employee or agent of any of our subsidiaries) as a result of service in such capacity. This right to indemnification includes the right to be paid the expenses incurred in defending any action, suit or proceeding in advance of its final disposition.

        As a result of these provisions, we may be unable to obtain damages from a director for breach of fiduciary duty.

Certain Bylaw Provisions

        Special Meetings.    Our bylaws provide that special meetings of our stockholders may only be called by a majority of our board, the chairman of our board, our president or holders of a majority of our outstanding voting stock. These provisions may make it more difficult for stockholders, other than a majority stockholder, to take an action that our board opposes.

26


        Advance Notice Provisions.    Our bylaws establish an advance written notice procedure for stockholders seeking:

        Our bylaws provide that only persons who are nominated by our board or by a stockholder who has given timely written notice to our secretary before the meeting to elect directors will be eligible for election as our directors. Our bylaws also provide that any matter to be presented at any meeting of stockholders must be presented either by our board or by a stockholder in compliance with the procedures in our bylaws. A stockholder must give timely written notice to our secretary of its, his or her intention to present a matter before an annual meeting of stockholders. Our board then will consider whether the matter is one that is appropriate for consideration by our stockholders under Delaware corporate law and the SEC's rules.

        To be timely, we must receive any stockholder notice at least 60 days before the meeting. A stockholder's notice must also contain the information specified in the bylaws. These provisions may prevent or deter some stockholders from bringing matters before a stockholders' meeting or from making nominations for directors at an annual meeting.

Transfer Agent and Registrar

        American Stock Transfer & Trust Company is the transfer agent and registrar for our common stock.

27



DESCRIPTION OF PREFERRED STOCK

        We may issue preferred stock from time to time in one or more classes or series, with the exact terms of each class or series established by our board. Without seeking stockholder approval, our board may issue preferred stock with voting and other rights that could adversely affect the voting power of the holders of our common stock.

        The rights, preferences, privileges and restrictions of the preferred stock of each series will be fixed by the certificate of designation relating to each series. A prospectus supplement relating to each series will specify the terms of the preferred stock, including:

        The issuance of preferred stock may delay, deter or prevent a change in control.

        We will describe the specific terms of a particular series of preferred stock in the prospectus supplement relating to that series. The description of preferred stock above and the description of the terms of a particular series of preferred stock in the prospectus supplement are not complete. You should refer to the applicable certificate of designation for complete information. The prospectus supplement will contain a description of U.S. federal income tax consequences relating to the preferred stock.

28



DESCRIPTION OF DEPOSITARY SHARES

        The description below and in the prospectus supplement is not complete. You should read the forms of deposit agreement and depositary receipts filed with the SEC in connection with the offering of each series of the preferred stock described below.

General

        We may, at our option, elect to offer fractional interests in shares of preferred stock, rather than shares of preferred stock. If we exercise that option, we will provide for a depositary to issue receipts for depositary shares, each of which will represent a fractional interest in a share of preferred stock.

        The shares of preferred stock underlying the depositary shares will be deposited under a separate deposit agreement between us and a bank or trust company depositary that has its principal office in the U.S. The prospectus supplement will include the name and address of the depositary. Subject to the terms of the deposit agreement, each owner of a depositary share will be entitled, in proportion to the applicable fractional interest in a share of preferred stock, to all the rights and preferences of the underlying preferred stock, including dividend, voting, redemption, conversion and liquidation rights. Depositary receipts will be issued for depositary shares.

        The depositary may issue temporary depositary receipts substantially identical to, and entitling the holders to all the rights pertaining to, the definitive depositary receipts. Definitive depositary receipts will then be prepared thereafter and temporary depositary receipts may be exchanged for definitive depositary receipts at our expense.

        Upon surrender of depositary receipts and payment of the charges provided in the deposit agreement, the depositary will deliver the whole shares of preferred stock underlying the depositary shares.

Dividends and Other Distributions

        The depositary will distribute all cash dividends or other cash distributions on the preferred stock, rounded to the nearest cent, to the record holders of depositary shares in proportion to the numbers of such depositary shares owned by them on the relevant record date. Fractions of one cent not so distributed will be added to the next sum received by the depositary for distribution to record holders of depositary shares.

        In the event of a non-cash distribution, the depositary will, if feasible, distribute property received by it to the record holders of depositary shares entitled to them. If the distribution is not feasible, the depositary may sell the property and distribute the net proceeds to such holders.

Redemption of Depositary Shares

        If we redeem the preferred stock underlying the depositary shares, the depositary will redeem the depositary shares from the proceeds of the redemption of the preferred stock held by the depositary. The depositary will mail notice of redemption not less than 30 or more than 60 days prior to the date fixed for redemption to the record holders of the depositary shares. The redemption price per depositary share will be equal to the applicable fraction of the redemption price per share payable with respect to the preferred stock. Whenever we redeem shares of preferred stock held by the depositary, the depositary will redeem the corresponding depositary shares as of the same redemption date. If less than all the depositary shares are to be redeemed, the depositary will select by lot or pro rata which depositary shares will be redeemed.

        After the redemption, the depositary shares called for redemption will no longer be deemed to be outstanding. All rights of the holders of the depositary shares will cease, except the right to receive the

29



money or other property to which the holders are entitled upon redemption and surrender of the depositary receipts for their depositary shares.

Voting the Preferred Stock

        The depositary will mail to the holders of depositary shares the information contained in any notice of meeting at which the holders of preferred stock are entitled to vote. Each record holder of depositary shares on the record date for the preferred stock may instruct the depositary to exercise its voting rights with respect to the depositary shares. The depositary will attempt to vote the number of shares of preferred stock underlying such depositary shares in accordance with these instructions. We will agree to take any action required to enable the depositary to vote the depositary shares. The depositary will abstain from voting shares of preferred stock to the extent it does not receive instructions from the holders of depositary shares relating to that preferred stock.

Amendment and Termination of the Deposit Agreement

        We and the depositary may amend the form of depositary receipt and any provision of the deposit agreement at any time. However, neither of us can make any amendment that would materially and adversely alter the rights of the existing holders of depositary shares without approval by the record holders of at least a majority of the outstanding depositary shares. We or the depositary may terminate a deposit agreement only if:

Charges of Depositary

        We will pay all transfer and other taxes and governmental charges arising solely from the depositary arrangements. We will pay charges of the depositary in connection with the initial deposit of the preferred stock and any redemption of the preferred stock. Holders of depositary shares will pay transfer and other taxes and governmental charges and any other charges listed in the deposit agreement as holders' charges.

Miscellaneous

        The depositary will forward to the holders of depositary shares all reports and communications that we are required to furnish to the holders of the preferred stock.

        Neither we nor the depositary will be liable if the law or any circumstance beyond the depositary's control prevents it from performing its obligations under the deposit agreement. We and the depositary will be required only to perform our and their respective duties in good faith. The depositary will not be obligated to prosecute or defend any legal proceeding regarding any depositary shares or preferred stock unless the holders of those securities provide it with satisfactory indemnity. The depositary may rely on written advice of counsel or accountants, or information provided by persons presenting preferred stock for deposit, holders of depositary shares or other persons believed to be competent and on documents believed to be genuine.

Resignation and Removal of Depositary

        The depositary may resign at any time by delivering notice to us, and we may at any time remove the depositary. Any such resignation or removal will take effect when a successor depositary is established.

30



DESCRIPTION OF STOCK PURCHASE UNITS AND STOCK PURCHASE CONTRACTS

        The following summarizes the general terms of stock purchase units and stock purchase contracts we may issue. The particular terms of any stock purchase units or stock purchase contracts we offer will be described in the prospectus supplement. This description is subject to the stock purchase contracts, and any collateral arrangements and depositary arrangements relating to the stock purchase or stock purchase contracts.

        We may issue stock purchase contracts, including contracts obligating holders to purchase from us, and us to sell to the holders, a specified number of shares of common stock or preferred stock at a future date or dates. We may fix the consideration per share of common stock or preferred stock at the time we issue the stock purchase contracts, or the consideration may be determined by referring to a specific formula stated in the stock purchase contracts. We may issue the stock purchase contracts separately or as a part of stock purchase units consisting of a stock purchase contract and debt securities, preferred securities or debt obligations of third parties, including U.S. Treasury securities, which secure the holders' obligations to purchase the common stock or preferred stock under the stock purchase contracts. The stock purchase contracts may require us to make periodic payments to the holders of the stock purchase units or vice versa. These payments may be unsecured or prefunded on some basis. The stock purchase contracts may require holders to secure their obligations in a specified manner.

31



DESCRIPTION OF WARRANTS TO PURCHASE DEBT SECURITIES

        The following summarizes the terms of the debt warrants we may offer. The debt warrants will be subject to the detailed provisions of a debt warrant agreement that we will enter into with a debt warrant agent we select at the time of issue.

General

        We may issue debt warrants evidenced by debt warrant certificates independently or together with any securities offered by any prospectus supplement. If we offer debt warrants, the prospectus supplement will describe the terms of the warrants, including:

        You may exchange debt warrant certificates for new debt warrant certificates of different denominations and may present debt warrant certificates for registration of transfer at the corporate trust office of the debt warrant agent, which will be listed in the prospectus supplement. Warrantholders do not have any of the rights of holders of debt securities, except to the extent that the consent of warrantholders may be required for certain modifications of the terms of an indenture or form of the debt security, as the case may be, and the series of debt securities issuable upon exercise of the debt warrants. In addition, warrantholders are not entitled to payments of principal of and interest, if any, on the debt securities.

Exercise of Debt Warrants

        You may exercise debt warrants by surrendering the debt warrant certificate at the corporate trust office of the debt warrant agent, with payment in full of the exercise price. Upon the exercise of debt warrants, the debt warrant agent will, as soon as practicable, deliver the debt securities in authorized denominations in accordance with your instructions and at your sole cost and risk. If less than all the debt warrants evidenced by the debt warrant certificate are exercised, the agent will issue a new debt warrant certificate for the remaining amount of debt warrants.

32



DESCRIPTION OF WARRANTS TO PURCHASE
COMMON STOCK OR PREFERRED STOCK

        The following summarizes the terms of common stock warrants and preferred stock warrants we may issue. This description is subject to the detailed provisions of a stock warrant agreement that we will enter into between us and a stock warrant agent we select at the time of issue.

General

        We may issue stock warrants evidenced by stock warrant certificates under a stock warrant agreement independently or together with any securities we offer by any prospectus supplement. If we offer stock warrants, the prospectus supplement will describe the terms of the stock warrants, including:


        The shares of common stock or preferred stock we issue upon exercise of the stock warrants will, when issued in accordance with the stock warrant agreement, be validly issued, fully paid and nonassessable.

Exercise of Stock Warrants

        You may exercise stock warrants by surrendering to the stock warrant agent the stock warrant certificate, which indicates your election to exercise all or a portion of the stock warrants evidenced by the certificate. Surrendered stock warrant certificates must be accompanied by payment of the exercise price in the form of cash, check or through a cashless exercise. The stock warrant agent will deliver certificates evidencing duly exercised stock warrants to the transfer agent. Upon receipt of the certificates, the transfer agent will deliver a certificate representing the number of shares of common stock or preferred stock purchased. If you exercise fewer than all the stock warrants evidenced by any certificate, the stock warrant agent will deliver a new stock warrant certificate representing the unexercised stock warrants.

No Rights as Stockholders

        Holders of stock warrants are not entitled to vote, to consent, to receive dividends or to receive notice as stockholders with respect to any meeting of stockholders or to exercise any rights whatsoever as our stockholders.

PLAN OF DISTRIBUTION

        We may sell the securities through underwriters or dealers, through agents, directly to one or more purchasers or through a combination of any such methods of sale. The applicable prospectus supplement will describe the terms of the offering of the securities, including:

        We may distribute the securities from time to time in one or more transactions:

        Only underwriters named in the prospectus supplement are underwriters of the securities offered by the prospectus supplement.

        If an underwriter is, or if underwriters are, used in the sale, they will acquire the securities for their own account and may resell them. We may offer the securities to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. Subject to certain conditions, the underwriters will be obligated to purchase all the securities of the series offered by the prospectus supplement. Any public offering price and any discounts or concessions allowed or reallowed or paid to dealers may change from time to time.

        We may sell securities directly or through agents we designate from time to time. We will name any agent involved in the offering and sale of securities and we will describe any commissions we will pay the agent in the prospectus supplement. Unless the prospectus supplement states otherwise, our agent will act on a best efforts basis for the period of its appointment.

        We may authorize agents or underwriters to solicit offers by certain types of institutional investors to purchase securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. We will describe the conditions to these contracts and the commissions we must pay for solicitation of these contracts in the prospectus supplement.

        We may provide agents and underwriters with indemnification against certain civil liabilities, including liabilities under the Securities Act, or contribution with respect to payments that the agents or underwriters may make with respect to such liabilities. Agents and underwriters may engage in transactions with, or perform services for, us in the ordinary course of business.

        In compliance with National Association of Securities Dealers, Inc. (NASD) guidelines, the maximum commission or discount to be received by any NASD member or independent broker-dealer will not exceed 8% of the aggregate amount of any sale of securities offered pursuant to this prospectus or any applicable prospectus supplement under Rule 415. All securities we offer other than common stock will be new issues of securities with no established trading market. Any underwriters may make a market in these securities, but will not be obligated to do so and may discontinue any

36



market making at any time without notice. We cannot guarantee the liquidity of the trading markets for any securities.

        The selling stockholders would only sell their shares of common stock through underwriters and only in connection with the exercise of any over-allotment option which may be granted to the underwriters. The selling stockholders may be deemed to be underwriters within the meaning of the Securities Act.


VALIDITY OF SECURITIES

        The validity of these securities will be passed upon for us by Piper Rudnick LLP, New York, New York, and for any underwriters, dealers or agents, if any, by counsel specified in a prospectus supplement.

Item 17. Undertakings.

        (a)   The undersigned registrant hereby undertakes:

II-2


        (b)   The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's 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.

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