	•	our ability to meet our projected cash needs over the next twelve months, to maintain borrowing flexibility and to refinance our borrowings beyond the next twelve months;

	•	risks associated with international operations including compliance with local legal and regulatory requirements;

	•	the potential effect of foreign currency fluctuations on revenues, expenses and resulting margins;

SUMMARY

This summary description of our business may not contain all the information that may be important to you. You should read this entire prospectus supplement and the accompanying prospectus, including the financial data and related notes included or incorporated by reference herein, before making an investment decision. The terms “Boston Scientific,” “our company” and “we” as used in this prospectus supplement refer to “Boston Scientific Corporation” and its subsidiaries and predecessors as a combined entity, except where it is made clear that such term means only the parent company.

Boston Scientific Corporation

Business

We are a worldwide developer, manufacturer and marketer of medical devices whose products are used in a broad range of interventional medical specialties, including interventional cardiology, peripheral interventions, neurovascular intervention, electrophysiology, vascular surgery, endoscopy, oncology, urology and gynecology. Since we were formed in 1979, we have advanced the practice of less-invasive medicine by providing a broad portfolio of innovative products, technologies and services across a wide range of medical specialties. Our products are generally inserted into the human body through natural openings or small incisions in the skin and can be guided to most areas of the anatomy to diagnose and treat a wide range of medical problems. These products help physicians and other medical professionals improve their patients’ quality of life by providing alternatives to surgery. We recorded net sales of $3.5 billion in 2003 and $1.1 billion in the first quarter of 2004.

Since 1995, we have undertaken a strategic acquisition program to assemble the lines of business necessary to achieve the critical mass that allows us to continue to be a leader in the medical industry. In 2003, we invested more than $350 million in approximately 25 strategic initiatives. These initiatives are each intended to further expand our product offerings by adding new or complementary technologies to our already diverse technology portfolio. As the health care environment continues to undergo rapid change, we expect that we will continue to focus on strategic acquisitions and alliances in order to provide new products and technology platforms to our customers. In addition, we expect to make additional investments in several of our existing relationships.

We operate through four business segments divided among the geographic regions of the United States, Europe, Japan and Inter-Continental. Maintaining and expanding our international presence is an important component of our long-term growth plan. Through our international presence, we seek to increase net sales and market share, leverage relationships with leading physicians and their clinical research programs, accelerate the time within which new products can be brought to market and gain access to worldwide technological developments that may be implemented across our product lines. Sales outside of the United States accounted for approximately 45 percent of our net sales in 2003 and in the first quarter of 2004.

Products

Our products are offered for sale by two dedicated business groups: Cardiovascular and Endosurgery. The Cardiovascular organization focuses on products and technologies for use in interventional cardiology, peripheral interventions, vascular surgery, electrophysiology, and neurovascular procedures. The Endosurgery organization focuses on products and technologies for use in oncology, endoscopy, urology and gynecology procedures. During 2003, approximately 72 percent of our net sales were derived from the Cardiovascular business and approximately 28 percent from the Endosurgery business. For the three months ended

S-6

March 31, 2004, approximately 76 percent of our net sales were derived from the Cardiovascular business and approximately 24 percent from the Endosurgery business.

Cardiovascular. Our principal Cardiovascular products are offered in the following medical areas:


• Coronary Stents		• Peripheral Interventions
• Coronary Revascularization		• Caval Interruption Systems
• Embolic Protection		• Electrophysiology
• Intraluminal Ultrasound Imaging		• Neurovascular Intervention
• Fluid Management		• Vascular Surgery

Endosurgery. Our principal Endosurgery products are offered in the following medical areas:


• Esophageal, Gastric and Duodenal (Small Intestine) Intervention		• Prostate Intervention
• Colorectal Intervention		• Urinary Incontinence
• Pancreatico-Biliary Intervention		• Gynecology
• Pulmonary Intervention		• Oncology Intervention
• Urinary Tract Intervention and Bladder Disease		• Central Venous Access

Strategy

Our mission is to improve the quality of patient care and the productivity of health care delivery through the development and advocacy of less-invasive medical devices and procedures. This is accomplished through the continuing refinement of existing products and procedures and the investigation and development of new technologies that can reduce risk, trauma, cost, procedure time and the need for aftercare. Our approach to innovation combines internally developed products and technologies with those obtained externally through strategic acquisitions and alliances. Building relationships with development companies and inventors helps us enrich our current franchises as well as expand into complementary businesses.

Key elements of our overall business strategy include the following:

Innovation. We are committed to harnessing technological innovation and our approach to technology innovation includes a mixture of tactical and strategic initiatives that are designed to offer sustainable growth in the near and long term. Combining internally developed products and technologies with those obtained through acquisition and alliances allows us to focus on and deliver products currently in our pipeline as well as strengthen our technology portfolio by accessing third party technologies.

Clinical Excellence. Our commitment to innovation is further demonstrated by our rapidly expanding clinical capabilities. Our clinical teams are organized by therapeutic specialty to better support our research and development pipeline and marketing and sales efforts.

Product Diversity. We offer products in numerous product categories, which are used by physicians throughout the world in a broad range of diagnostic and therapeutic procedures. The breadth and diversity of our product lines permit medical specialists and purchasing organizations to satisfy many of their less-invasive medical device requirements from a single source.

Operational Excellence. We are focused on continuously improving our supply chain effectiveness, strengthening our manufacturing processes and optimizing our plant network in

S-7

order to increase operational efficiencies within the organization. By centralizing operations at the corporate level and shifting global manufacturing along product lines, we believe we are able to leverage our existing resources and concentrate on new product development, including enhancement of existing products, and their commercial launch.

Focused Marketing. Each of our business groups maintain dedicated sales forces and marketing teams focusing on physicians who specialize in the diagnosis and treatment of different medical conditions. We believe that this focused disease state management enables us to develop highly knowledgeable and dedicated sales representatives and to foster close professional relationships with physicians.

Active Participation In The Medical Community. We believe that we have excellent working relationships with physicians and others in the medical industry, which enable us to gain a detailed understanding of new therapeutic and diagnostic alternatives, and to respond quickly to the changing needs of physicians and patients. Active participation in the medical community contributes to physician understanding and adoption of less-invasive techniques and the expansion of these techniques into new therapeutic and diagnostic areas.

Corporate Culture. Our management believes that success and leadership evolve from a motivating corporate culture which rewards achievement, respects and values individual employees and customers, and focuses on quality, technology, integrity and service. We believe that our success is attributable in large part to the high caliber of our employees and our commitment to respecting the values on which our success has been based.

Recent Developments

On June 1, 2004, we acquired 100 percent of the fully diluted equity of Advanced Bionics Corporation, a privately-held company located in Valencia, California, for an initial payment of approximately $740 million in cash, plus earn out payments tied to future performance milestones. The initial purchase price was funded by the issuance of commercial paper.

The acquisition will expand our technology portfolio into the rapidly growing implantable microelectronic device market. Advanced Bionics has developed implantable microelectronics for treating numerous neurological disorders. Its neuromodulation technology includes a range of neurostimulators (or implantable pulse generators), programmable drug pumps and cochlear implants.

The acquisition has been structured to include a substantial earnout mechanism. Performance milestones are primarily based on the achievement of net sales, with certain milestone payments also tied to profitability. The milestones are segmented by the four principal technology platforms (cochlear implants, implantable pulse generators, drug pumps and bion microstimulators), each with a 72-month earnout horizon. Base earnout payments on these performance milestones approximate two and a quarter times incremental sales for each annual period. There are also bonus earnout payments available based on the attainment of certain aggregate sales performance targets and a certain gross margin level.

Our best estimate of future contingent consideration (undiscounted) that we would be required to make associated with our acquisition of Advanced Bionics is approximately $2.0 billion. The estimated cumulative specified revenue level associated with our best estimate is approximately $4.5 billion during the period from 2004 through 2013.

Our principal executives offices are located at One Boston Scientific Place, Natick, MA 01760-1537. Our telephone number is (508) 650-8000. Our website is located at www.bostonscientific.com.

USE OF PROCEEDS

We estimate that the net proceeds to us from this notes offering will be approximately $ million after deducting estimated underwriting discounts and commissions, and estimated expenses. A significant portion of the net proceeds from this notes offering will be used to repay commercial paper borrowings. The amount outstanding under our commercial paper program as of March 31, 2004 was approximately $946 million, at a weighted average interest rate of 1.13 percent per year, which rate is subject to change over time. Our commercial paper borrowings financed strategic alliances and acquisitions, facility expansions, common stock repurchases and other general corporate purposes. Approximately $740 million of commercial paper borrowings were incurred after March 31, 2004 to finance our recent acquisition of Advanced Bionics Corporation. See “Summary — Recent Developments.” We expect to use the remainder of the net proceeds of this offering, if any, principally for general corporate purposes.

To the extent that the net proceeds are not used immediately for the above purposes, these funds will be invested in short- and/or medium-term investment grade securities.

DESCRIPTION OF THE NOTES

The following description of the particular terms of the notes offered hereby (referred to in the accompanying prospectus as the “Debt Securities”) supplements, and to the extent inconsistent therewith replaces, the description of the general terms and provisions of the Debt Securities set forth in the accompanying prospectus under the caption “Description of Debt Securities”, to which description reference is hereby made. Capitalized terms not defined in this section have the meanings assigned to such terms in the accompanying prospectus.

General

The notes offered hereby will be limited initially to $500 million aggregate principal amount and will mature on , 2014. The notes will not be entitled to a sinking fund. Interest at the applicable annual rate set forth on the cover page of this prospectus supplement will be payable semiannually on and , commencing , 2004, to the persons in whose names the notes are registered at the close of business on or , as the case may be, preceding such interest payment date. Interest on the notes will accrue from , 2004 or from the most recent interest payment date to which interest has been paid or provided for to, but excluding, the next interest payment date. The notes constitute a separate series of Debt Securities under the Indenture to be dated on or about June , 2004, between us and the trustee (the “Indenture”), and will be issued in denominations of $1,000 and integral multiples thereof.

The notes will be unsecured and will rank on a parity with each other and with all other of our unsecured and unsubordinated indebtedness from time to time outstanding. The notes will rank senior to any future unsecured and subordinated debt, effectively junior to our secured debt and effectively junior to liabilities of our subsidiaries, in each case as may be outstanding from time to time.

The provisions described in the accompanying prospectus under “Description of Debt Securities” will be applicable to the notes, except to the extent such provisions are inconsistent with this Description of the Notes. In particular, the Limitation on Liens covenant described below replaces the Limitation on Liens covenant found in the accompanying prospectus under the caption “Description of Debt Securities” in its entirety.

We may create and issue further notes ranking equally and ratably with the notes in all respects, so that such further notes will be consolidated and form a single series with the notes and will have the same terms as to status, redemption or otherwise as the notes.

Limitation on Liens

We will not, and will not permit any of our Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien upon any of our property, assets or revenues, whether now owned or hereafter acquired, except for: (i) Liens for taxes not yet due or which are being contested in good faith by appropriate proceedings; provided that adequate reserves with respect thereto are maintained on our or our Subsidiaries’ books, as the case may be, in conformity with GAAP; (ii) carriers’, warehousemen’s, mechanics’, materialmen’s, repairmen’s or other like Liens arising in the ordinary course of business that are not overdue for a period of more than 60 days or which are being contested in good faith by appropriate proceedings; (iii) pledges or deposits in connection with workers’ compensation, unemployment insurance and other social security legislation and deposits securing liability to insurance carriers under insurance or self-insurance arrangements; (iv) deposits to secure the performance of bids, trade contracts (other than for borrowed money), leases, statutory obligations, surety and appeal bonds, performance bonds and other obligations of a like nature incurred in the ordinary course of business; (v) easements, rights-of-way, restrictions and other similar encumbrances incurred in the ordinary course of business which, in the aggregate, are not substantial in

S-15

amount and which do not in any case materially detract from the value of the property subject thereto or materially interfere with the ordinary conduct of our business or that of such Subsidiary; (vi) Liens in existence on the date of the first issuance by us of Senior Debt Securities issued pursuant to the Indenture; provided that no such Lien is spread to cover any additional property after such date and that the amount of Debt secured thereby is not increased; (vii) Liens securing our and our Subsidiaries’ Debt incurred to finance the acquisition of fixed or capital assets; provided that (A) such Liens will be created substantially simultaneously with the acquisition of such fixed or capital assets, (B) such Liens do not at any time encumber any property other than the property financed by such Debt and (C) the amount of Debt secured thereby is not increased; (viii) Liens on the property or assets of a corporation that becomes a Subsidiary after the date hereof; provided that (A) such Liens existed at the time such corporation became a Subsidiary and were not created in anticipation thereof, (B) any such Lien is not spread to cover any property or assets or such corporation after the time such corporation becomes a Subsidiary, and (C) the amount of Debt secured thereby is not increased; (ix) Liens pursuant to any Receivables Transactions in an aggregate principal amount not exceeding 20% of Consolidated Tangible Assets, and (x) Liens (not otherwise permitted hereunder) (A) which secure obligations not exceeding the greater of (X) $100.0 million or (Y) 20% of Consolidated Net Worth, in each case in aggregate amount at any time outstanding, or (B) with respect to which we effectively provide that the Senior Debt Securities outstanding under the Indenture are secured equally and ratably with (or, at our option prior to) the Debt secured by such Liens.

Optional Redemption

We may redeem the notes, in whole or in part, at our option, at any time at a redemption price equal to the greater of:


	•	100% of the principal amount of the notes to be redeemed or

	•	as determined by a Quotation Agent (as defined below), the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest accrued to the date of redemption) discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate (as defined below) plus basis points

plus, in each case, accrued and unpaid interest on the notes to the redemption date.

“Adjusted Treasury Rate” means, with respect to any redemption date, the rate per year equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.

“Comparable Treasury Issue” means the United States Treasury security selected by a Quotation Agent as having maturity comparable to the remaining term of the notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such notes.

“Quotation Agent” means the Reference Treasury Dealer appointed by the trustee after consultation with us.

“Reference Treasury Dealer” means (1) Banc of America Securities LLC, Deutsche Bank Securities Inc. and J.P. Morgan Securities Inc. and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary United States Government securities dealer in New York City (a “Primary Treasury Dealer”), we shall substitute therefore another

S-16

Primary Treasury Dealer; and (2) any other Primary Treasury Dealers selected by the trustee after consultation with us.

“Comparable Treasury Price” means, with respect to any redemption date, (1) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (2) if the trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the trustee, of the bid and ask prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the trustee by such Reference Treasury Dealer at 5:00 p.m. on the third business day preceding such redemption date.

We will give notice to The Depository Trust Company (“DTC”) of any redemption we propose to make at least 30 days, but not more than 60 days, before the redemption date. If we redeem only some of the notes, it is the practice of DTC to determine by lot the amount of notes to be redeemed of each of its participating institutions. Notice by DTC to these participants and by participants to “street name” holders of indirect interests in the notes will be made according to arrangements among them and may be subject to statutory or regulatory requirements.

Unless we default in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the notes or portions of the notes called for redemption.

Sinking Fund

The notes will not be entitled to the benefit of a sinking fund.

Defeasance

The notes are subject to the company’s defeasance option. See “Description of Debt Securities — Defeasance” in the accompanying prospectus.

Book-Entry Procedures

The notes will be issued in the form of one or more fully registered Global Securities (the “Global Securities”), which will be deposited with, or on behalf of, DTC (the “Depositary”), and registered in the name of the Depositary’s nominee. Except as set forth below, the Global Securities may be transferred, in whole or in part, only to another nominee of the Depositary or to a successor of the Depositary or its nominee.

The Depositary has advised us and the underwriters as follows: The Depositary is a limited-purpose trust company that was created to hold securities for its participating organizations (the “Participants”) and to facilitate the clearance and settlement of securities transactions between Participants in such securities through electronic book-entry changes in accounts of its Participants. Participants include securities brokers and dealers (including certain of the underwriters), banks (including the trustee) and trust companies, clearing corporations and certain other organizations. Access to the Depositary’s system is also 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 (“indirect participants”). Persons who are not Participants may beneficially own securities held by the Depositary only through Participants or indirect participants.

Pursuant to procedures established by the Depositary, (i) upon issuance of the notes by us, the Depositary will credit the accounts of Participants designated by the underwriters with the principal amounts of the notes purchased by the underwriters, and (ii) ownership of beneficial

S-17

interests in the Global Securities will be shown on, and the transfer of that ownership will be effected only through, records maintained by the Depositary (with respect to the Participants’ interests), the Participants and the indirect participants. The laws of some states require that certain persons take physical delivery in definitive form of securities that they own. Consequently, the ability to transfer beneficial interests in the Global Securities is limited to such extent.

So long as a nominee of the Depositary is the registered owner of the Global Securities, such nominee for all purposes will be considered the sole owner or holder of the corresponding notes under the Indenture. Except as provided below, owners of beneficial interests in the Global Securities will not be entitled to have notes registered in their names, will not receive or be entitled to receive physical delivery of notes in definitive form, and will not be considered the owners or holders thereof under the Indenture.

The trustee, any Paying Agent and the Security Registrar will not have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the Global Securities, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

Principal and interest payments on the notes registered in the name of the Depositary’s nominee will be made by the trustee to the Depositary’s nominee as the registered owner of the Global Securities. Under the terms of the Indenture, we and the trustee will treat the persons in whose names the notes are registered as the owners of such notes for the purpose of receiving payment of principal and interest on the notes and for all other purposes whatsoever. Therefore, neither we, the trustee nor any Paying Agent has any direct responsibility or liability for the payment of principal or interest on the notes to owners of beneficial interests in the Global Securities. The Depositary has advised the trustee and us that its present practice is, upon receipt of any payment of principal or interest, to immediately credit the accounts of the Participants with such payment in amounts proportionate to their respective holdings in principal amount of beneficial interests in the Global Securities as shown on the records of the Depositary. Payments by Participants and indirect participants to owners of beneficial interests in the Global Securities will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in “street name” and will be the responsibility of the Participants or indirect participants.

If the Depositary 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 issue notes in definitive form in exchange for the Global Securities. In addition, we may at any time determine not to have the notes represented by Global Securities and, in such event, will issue notes in definitive form in exchange for the Global Securities. In either instance, an owner of a beneficial interest in the Global Securities will be entitled to have notes equal in principal amount to such beneficial interest registered in its name and will be entitled to physical delivery of such notes in definitive form. Notes so issued in the definitive form will be issued in denominations of $1,000 and integral multiples thereof and will be issued in registered form only, without coupon.

S-18

UNDERWRITING

Subject to the terms and conditions set forth in the underwriting agreement and a terms agreement each dated , 2004, each of the underwriters has severally agreed to purchase, and we have agreed to sell to each underwriter, the principal amount of notes set forth opposite the name of each underwriter:




		Principal Amount
Underwriters		of Notes


Banc of America Securities LLC		$
Deutsche Bank Securities Inc.
J.P. Morgan Securities Inc.

	Total	$	500,000,000

Under the terms and conditions of the underwriting agreement, if the underwriters take any of the notes, then they are obligated to take and pay for all the notes.

The notes are a new issue of securities with no established trading market and will not be listed on any national securities exchange. The underwriters have advised us that they intend to make a market for the notes, but they have no obligation to do so and may discontinue market-making at any time without providing any notice. No assurance can be given as to the liquidity of any trading market for the notes.

The underwriters initially propose to offer part of the notes directly to the public at the offering price described on the cover page of this prospectus supplement and part of the notes to certain dealers at a price that represents a concession not in excess of % of the principal amount of the notes. The underwriters may allow, and any such dealer may reallow, a concession not in excess of % of the principal amount of the notes to certain other dealers. After the initial offering of the notes, the underwriters may from time to time vary the offering price and other selling terms.

We have also agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments which the underwriters may be required to make in respect of any such liabilities.

In connection with the offering of the notes, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the notes. Specifically, the underwriters may overallot in connection with the offering of the notes, creating a short position. In addition, the underwriters may bid for, and purchase, notes in the open market to cover short positions or to stabilize the price of the notes. Any of these activities may stabilize or maintain the market price of the notes above independent market levels. The underwriters are not required to engage in any of these activities, and may end any of them at any time.

Our expenses associated with this offering, to be paid by us, are estimated to be $925,000.

Certain of the underwriters will make the notes available for distribution on the internet through a proprietary web site and/or a third-party system operated by Market Axess Corporation, an internet-based communications technology provider. Market Axess Corporation is providing the system as a conduit for communications between those underwriters and their respective customers and is not a party to any transactions. Market Axess Corporation, a registered broker-dealer, will receive compensation from those underwriters based on transactions they conduct through the system. Those underwriters will make the notes available to their respective customers through the Internet distributions, whether made through a proprietary or third-party system, on the same terms as distributions made through other channels.

S-19

In the ordinary course of their respective businesses, certain of the underwriters or their affiliates have engaged, and may in the future engage, in commercial banking and/or investment banking transactions with us and our affiliates. In particular, certain of the underwriters or their affiliates, are lenders under our revolving credit facilities.

LEGAL MATTERS

Certain legal matters in connection with the notes will be passed upon for us by Shearman & Sterling LLP, New York, New York, and for underwriters by Simpson Thacher & Bartlett LLP, New York, New York.

The Company and the Trusts do not consider that such financial statements would be material to holders of Trust Preferred Securities because (i) all of the voting securities of each Trust are owned, directly or indirectly, by the Company, a reporting company under the Exchange Act, (ii) each of the Trusts has and will have no independent operations, but exists for the sole purpose of issuing securities representing undivided beneficial interests in its assets and investing the proceeds thereof in Subordinated Debt Securities issued by the Company, and (iii) the Company’s obligations, which are described herein and in any accompanying Prospectus Supplement, pursuant to each Declaration (as defined herein) (including the obligation to pay the expenses of each Trust), the Indenture and any supplemental indentures thereto, the Subordinated Debt Securities issued to any of the Trusts and the Trust Guarantees, taken together, constitute a full and unconditional guarantee, on a subordinated basis, by the Company of payments due on the Trust Preferred Securities. See “The Trusts,” “Description of Trust Preferred Securities” and “Description of Trust Guarantee.”

None of the Trusts are currently subject to the information reporting requirements of the Exchange Act. Upon the effectiveness of the Registration Statement, each Trust will become subject to such requirements; however, each of the Trusts intends to seek and expects to receive exemption therefrom. Each of the Trusts is a newly formed special purpose entity, has no operating history or independent operations and is not engaged in and does not propose to engage in any activity other than its holding as trust assets the Subordinated Debt Securities and the issuance of the Trust Securities.

THE COMPANY

The Company is a worldwide developer, manufacturer and marketer of minimally invasive medical devices. Medical professionals use the Company’s products in a broad range of interventional medical specialties, including cardiology, gastroenterology, neuro-endovascular therapy, pulmonary medicine, radiology, urology and vascular surgery. The Company’s products are generally inserted into the human body through natural openings or small incisions in the skin and can be guided to most areas of the anatomy to diagnose and treat a wide range of medical problems. These products provide effective alternatives to traditional surgery by reducing procedural trauma, complexity, risk to the patient, cost and recovery time. In recent years, the Company has bolstered its growth through several strategic acquisitions and alliances. Most recently, on September 10, 1998, the Company acquired Schneider Worldwide, formerly a member of the Medical Technology Group of Pfizer Inc. (“Pfizer”), for approximately $2.1 billion in cash. The purchase price was funded by the issuance of commercial paper.

The principal executive offices of the Company are located at One Boston Scientific Place, Natick, Massachusetts 01760-1537. Its telephone number is (508) 650-8000.

TRUSTS

Each Trust is a statutory business trust formed under Delaware law pursuant to (i) a separate declaration of trust (each, as amended and restated, a “Declaration”) executed by the Company as sponsor for such trust (the “Sponsor”), the Regular Trustees (as defined herein) and the Delaware Trustee (as defined herein) of such trust and (ii) the filing of a certificate of trust with the Secretary of State of the State of Delaware on September 25, 1998, with respect to BSC Capital Trust, and on September 29, 1998, with respect to the other Trusts. The Company and each Institutional Trustee (as defined herein) will qualify the applicable Declaration as an indenture under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). Each Trust exists for the exclusive purposes of (i) issuing and selling Trust Securities, (ii) investing the gross proceeds from the sale of such Trust Securities in Subordinated Debt Securities and (iii) engaging in only those other activities necessary or incidental thereto.

The Company will own directly or indirectly all of the Trust Common Securities of each Trust. The Trust Common Securities of each Trust will rank pari passu, and the applicable Trust will make payments thereon pro rata, with the Trust Preferred Securities of such Trust except that, if any event of default has occurred and is continuing under its Declaration, the rights of holders of the Trust Common Securities to payment in respect of distributions and payments upon liquidation, redemption or otherwise will be subordinated to the rights of holders of the Trust Preferred Securities of such Trust. The Company will acquire Trust Common Securities of each of the Trusts in an aggregate liquidation amount equal to at least 3% of the total capital of each such Trust.

The term of each Trust is approximately 45 years, but each Trust may be dissolved earlier as provided in its Declaration. The business and affairs of each of the Trusts will be conducted by the trustees (the “Capital Trustees”) appointed by the Company as the direct or indirect holder of all of the Trust Common Securities of each such Trust. As holder of the Trust Common Securities, the Company will be entitled to appoint, remove or replace any of, or increase or reduce the number of Capital Trustees of each of the Trusts. The applicable Declaration governs the duties and obligations of the Capital Trustees. A majority of the Capital Trustees (the “Regular Trustees”) of each of the Trusts will be persons who are employees or officers of, or who are affiliated with, the Company. One Capital Trustee of each Trust will be a financial institution that is unaffiliated with the Company and has minimum capital and surplus of not less than $50.0 million. That institution acts as property trustee and as indenture trustee (the “Institutional Trustee”) for the purpose of compliance with the provisions of the Trust

Indenture Act pursuant to terms set forth in the applicable Prospectus Supplement. In addition, unless the Institutional Trustee for a Trust maintains a principal place of business in the State of Delaware and otherwise meets the requirements of applicable law, one Capital Trustee of such Trust will be an entity having a principal place of business in, or a natural person resident of, the State of Delaware (the “Delaware Trustee”). The Company will pay all fees and expenses related to the Trusts and any offering of Trust Securities.

The rights of the holders of the Trust Preferred Securities, including economic rights, rights to information and voting rights, are set forth in Declaration, the Delaware Business Trust Act, as amended (the “Trust Act”), and the Trust Indenture Act. See “Description of Trust Preferred Securities.”

Unless otherwise specified in the applicable Prospectus Supplement, the Institutional Trustee for each of the Trusts is The Chase Manhattan Bank; Attention: Corporate Trust Administration. Unless otherwise specified in the applicable Prospectus Supplement, The Chase Manhattan Bank Delaware will serve as the Delaware Trustee for each of the Trusts, and its address in the State of Delaware is 1201 North Market Street, Wilmington, New Castle County, Delaware 19801, Attention: Corporate Trust Administration. The principal place of business of each of the Trusts is c/o Boston Scientific Corporation, One Boston Scientific Place, Natick, Massachusetts 01760-1537, telephone number (508) 650-8000.

USE OF PROCEEDS

The Company intends to use the net proceeds from the sale of the Securities (including Subordinated Debt Securities issued to any of the Trusts in connection with the investment by any such Trust of all of the proceeds from the sale of Trust Preferred Securities) for general corporate purposes, including, without limitation, repurchases or redemptions of the Company’s outstanding debt securities or other reductions of the Company’s outstanding borrowings, working capital, business acquisitions, investments in or loans to subsidiaries, capital expenditures or for such other purposes as may be specified in the applicable Prospectus Supplement.

RATIO OF EARNINGS TO FIXED CHARGES

The ratios of earnings to fixed charges of the Company on a consolidated basis for the periods indicated were as follows (unaudited):



	Three Months
	Ended March 31,				Year Ended December 31,

	1999		1998		1998			1997		1996		1995		1994

Ratio of earnings to fixed charges		4.99		8.44					7.24		15.76		5.07		16.98
Coverage deficiency (in thousands)					$	(279,774	)

For purposes of calculating the ratio of earnings to fixed charges, “earnings” consist of income (loss) before income taxes and the cumulative effect of a change in accounting plus net distributed equity in earnings of equity investees and fixed charges less capitalized interest. “Fixed charges” consist of interest expense, capitalized interest, amortization of debt issuance expenses and discount and an appropriate portion of rental expense that represents a reasonable approximation of the interest factor. “Coverage deficiency” consists of earnings, as defined above, less fixed charges.

The ratios of earnings to fixed charges for all periods presented are not necessarily indicative of the results that may be expected for any future periods, and reflect merger-related and special charges recorded in conjunction with the Company’s acquisitions and strategic alliances consummated through March 31, 1999. The Company had a coverage deficiency in 1998 as a result of noncash special charges of $646 million recorded in connection with the acquisition of Schneider Worldwide and other merger-related initiatives. These ratios should be read in conjunction with the Company’s consolidated financial statements (including notes thereto) included in the 1998 Form 10-K and the Company’s condensed consolidated financial statements (including notes thereto) included in the March 1999 Form 10-Q.

	(xxvi) any other terms, conditions, rights and preferences relating to such Debt Securities.

With respect to Debt Securities of any series denominated in U.S. dollars, the Registered Securities of such series, other than Registered Securities issued in global form (which may be of any denomination), will be issuable in denominations of $1,000 and any integral multiple thereof and the Bearer Securities of such series, other than Bearer Securities issued in global form (which may be of any denomination), will be issuable in a denomination of $5,000, unless otherwise provided in the applicable Prospectus Supplement. The Prospectus Supplement relating to a series of Debt Securities denominated in any currency other than U.S. dollars or a composite currency will specify the denominations thereof.

One or more series of Debt Securities may be sold at a substantial discount below their stated principal amount, bearing no interest or interest at a rate which is below market rates at the time of issuance. One or more series of Debt Securities may be floating rate debt securities which are exchangeable for fixed rate debt securities. The Company will describe certain federal income tax consequences and special considerations, if any, applicable to each series of Debt Securities in the Prospectus Supplement relating thereto.

Unless otherwise indicated in the applicable Prospectus Supplement, interest, if any, on any Registered Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date will be paid to the Person in whose name such Security is registered at the close of business on the Regular Record Date for such interest at the office or agency of the Company maintained for such purpose as set forth in the Indenture; provided, however, that the Company may, at its option, pay each installment of interest, if any, on any Registered Security by (i) mailing a check for such interest installment, payable to or upon the written order of the Person entitled thereto as set forth in the Indenture, to the address of such Person as it appears on the Security Register or (ii) transferring an amount equal to such interest installment to an account located in the United States maintained by the payee.

Holders may present Debt Securities for exchange and may present registered Debt Securities for transfer, in the manner, at the places and subject to the restrictions set forth in the Indenture and the Debt Securities and described in the applicable Prospectus Supplement. The Company will charge no service fees for any transfer or exchange of the Debt Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Global Securities

The Debt Securities of a series may be issued in whole or in part in the form of one or more fully registered Global Securities that will be deposited with, or on behalf of, a depositary (the “Depositary”) identified in the Prospectus Supplement relating to such series. Unless and until it is exchanged in whole or in part for Debt Securities in definitive registered form, a Global Security may not be transferred except as a whole by the Depositary for such Global Security to a nominee of such Depositary or by a nominee of such Depositary to such Depositary or another nominee of such Depositary or by such Depositary or any such nominee to a successor of such Depositary or a nominee of such successor.

The specific terms of the Depositary arrangement with respect to any Debt Securities of a series will be described in the Prospectus Supplement relating to such series. The Company anticipates that the following provisions will apply to all Depositary arrangements.

Upon the issuance of a Global Security, the Depositary for such Global Security will credit, on its book-entry registration and transfer system, the respective principal amounts of the Debt Securities represented by such Global Security to the accounts of persons that have accounts with such Depositary (“participants”). The accounts to be credited shall be designated by the

underwriters or agents with respect to such Debt Securities or by the Company if such Debt Securities are offered and sold directly by the Company. Ownership of beneficial interests in a Global Security will be limited to participants or persons that may hold interests through participants. Ownership of participant’s interests in a Global Security will be shown on, and the transfer of that ownership will be effected only through, records maintained by the Depositary for such Global Security. Ownership of beneficial interests in a Global Security will be shown on, and the transfer of that ownership will be effected only through, records maintained by participants or persons that hold through participants. The laws of some states require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limits and such laws may impair the ability to transfer beneficial interests in a Global Security.

So long as the Depositary for a Global Security, or its nominee, is the registered owner of such Global Security, such Depositary or such nominee, as the case may be, will be considered the sole owner or holder of the Debt Securities represented by such Global Security for all purposes under the Indenture. Except as set forth below, owners of beneficial interests in a Global Security will not be entitled to have Debt Securities of the series represented by such Global Security registered in their names, will not receive or be entitled to receive physical delivery of Debt Securities of such series in definitive form and will not be considered the owners or holders thereof under the Indenture.

Principal, premium, if any, and any interest payments on Debt Securities registered in the name of a Depositary or its nominee will be made to the Depositary or its nominee, as the case may be, as the registered owner of a Global Security representing such Debt Securities. None of the Company, the Trustee, any Paying Agent or the Security Registrar for such Debt Securities will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the Global Security or Securities for such Debt Securities or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

The Company expects that the Depositary for a series of Debt Securities, upon receipt of any payment of principal, premium or interest, will credit immediately participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the Global Security or Securities for such Debt Securities as shown on the records of such Depositary. The Company also expects that payments by participants to owners of beneficial interests in such Global Security or Securities held through such participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such participants.

Further, if the Company so specifies 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 the Company, receive Debt Securities of such series in definitive form. In any such instance, an owner of a beneficial interest in a Global Security will be entitled to have Debt Securities of the series represented by such Global Security equal in principal amount to such beneficial interest registered in its name and will be entitled to physical delivery of such Debt Securities in definitive form.

Events of Default

The Indenture provides that the following shall constitute Events of Default with respect to any series of Debt Securities thereunder:


	(i) default in the payment of any interest on any Debt Security of such series, when it becomes due and payable, and continuance of such default for a period of 30 days;


	(ii) default in the payment of the principal of or premium, if any, on any Debt Security of such series when due either at its Maturity, upon acceleration, redemption or otherwise;

	(iii) default in the deposit of any sinking fund payment, when and as due by the terms of the Debt Securities of such series and the Indenture;

	(iv) default in the performance, or breach, of any covenant or agreement of the Company in the Indenture which affects or is applicable to Debt Securities of such series (other than a default in the performance, or breach of a covenant or agreement which is specifically dealt with elsewhere in the Indenture), and continuance of such default or breach for a period of 60 days after there has been given to the Company by the Trustee, or to the Company and the Trustee by Holders of at least 25% in aggregate principal amount of all outstanding Securities of such series, a written notice thereof;

	(v) certain events in bankruptcy, insolvency or reorganization of the Company; and

	(vi) any other Event of Default provided with respect to Debt Securities of such series.

No Event of Default with respect to a particular series of Debt Securities issued under the Indenture necessarily constitutes an Event of Default with respect to any other series of Debt Securities issued thereunder.

The Indenture provides that if an Event of Default specified in clause (i), (ii), (iii), (iv) or (vi) above occurs and is continuing, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Outstanding Debt Securities of such series may declare the principal of all such Debt Securities (or, in the case of Original Issue Discount Securities or Indexed Securities, such portion of the principal amount thereof as may be specified in the terms thereof) to be due and payable immediately. If an Event of Default specified in clause (v) above occurs and is continuing, then the principal of all such Debt Securities (or, in the case of Original Issue Discount Securities or Indexed Securities, such portion of the principal amount thereof as may be specified in the terms thereof) will be due and payable immediately, without any declaration or other act on the part of the Trustee or any Holder. In certain cases, Holders of a majority in principal amount of the outstanding Debt Securities of any series may, on behalf of Holders of all such Debt Securities, rescind and annul a declaration of acceleration.

The Indenture provides that the Trustee will not be liable for any action taken, suffered or omitted by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by the Indenture. The Indenture provides that no Holder of Debt Securities of any series may institute any proceedings, judicial or otherwise, to enforce the Indenture except in the case of failure of the Trustee thereunder to act for 60 days after it has received a request to enforce the Indenture by Holders of at least 25% in aggregate principal amount of the then Outstanding Debt Securities of such series (in the case of an Event of Default specified in clause (i), (ii), (iii), (iv) or (vi) above) or a request to enforce the Indenture by Holders of at least 25% in aggregate principal amount of all of the Debt Securities then Outstanding (in the case of an Event of Default specified in clause (v) above), and an offer of reasonable indemnity. This provision will not prevent any Holder of Debt Securities from enforcing payment of principal thereof, and premium, if any, and interest, if any, thereon at the respective due dates thereof. Holders of a majority in aggregate principal amount of the Debt Securities of any series then outstanding 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 on it with respect to Debt Securities of such series. The Trustee may, however, refuse to follow any direction that it determines may not lawfully be taken or would be illegal or in conflict with such Indenture or involve it in personal liability or which would be unjustly prejudicial to Holders not joining therein.

The Indenture provides that the Trustee will, within 90 days after the occurrence of a default with respect to any series of Debt Securities thereunder, give to Holders of Debt Securities of such series notice of such default if such default has not been cured or waived. Except in the case of a default in the payment of principal of, or premium, if any, or interest on, or in the payment of any sinking fund installment in respect of, any Debt Securities of such series, the Trustee will be protected in withholding such notice if it determines in good faith that the withholding of such notice is in the interest of Holders of the Debt Securities of such series.

The Company will be required to file annually with the Trustee an Officers’ Certificate as to compliance with all conditions and covenants under the terms of the Indenture.

Modification and Waiver

Modifications of and amendments to the Indenture may be made by the Company and the Trustee thereunder with the consent of Holders of a majority in principal amount of the outstanding Debt Securities of each series issued under the Indenture that is affected by such modification or amendment; provided, however, that no such modification or amendment may, without the consent of the Holder of each Outstanding Debt Security affected thereby: (i) change the Stated Maturity of the principal of, or premium, if any, or any installment of interest on any Debt Security of such series, or reduce the principal amount thereof, or premium, if any, or the rate of interest, if any, thereon, or change any obligation of the Company to pay Additional Amounts (except as contemplated or permitted by the Indenture), or reduce the amount of principal of an Original Issue Discount Security of such series that would be due and payable upon a declaration of acceleration of the Maturity thereof or the amount thereof provable in bankruptcy, or adversely affect any right of repayment at the option of any Holder of any Debt Security of such series, or change any Place of Payment where, or the currency in which, any Debt Security of such series or premium, if any, or interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof (or, in the case of redemption or repayment at the option of the Holder, on or after the Redemption Date or Repayment Date, as the case may be), or adversely affect any right to convert or exchange any Debt Security; (ii) reduce the percentage in principal amount of the Outstanding Debt Securities of any series, the consent of whose Holders is required for any supplemental indenture, for any waiver of compliance with certain provisions of the Indenture or certain defaults applicable to such series thereunder and their consequences provided for in the Indenture, or reduce the quorum or voting with respect to Debt Securities of such series; or (iii) modify any of the provisions relating to supplemental indentures requiring the consent of Holders or relating to the waiver of past defaults or relating to the waiver of certain covenants, except to increase any such percentage or to provide that certain other provisions of the Indenture which affect such series cannot be modified or waived without the consent of the Holder of each Outstanding Debt Security affected thereby.

The Company may, with respect to any series of Debt Securities, omit in any particular instance to comply with certain restrictive provisions of the Indenture if Holders of at least a majority in principal amount of all Outstanding Debt Securities affected by such term, provision or condition, by Act of such Holders, waive such compliance in such instance with such term, provision or condition, but no such waiver will extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver will become effective, the obligations of the Company and the duties of the Trustee to Holders of Debt Securities of such series in respect of any such term, provision or condition will remain in full force and effect. Holders of a majority in principal amount of the outstanding Debt Securities of each series (in the case of an Event of Default specified in clause (i), (ii), (iii), (iv) or (vi) in “Events of Default,” above) or the Holders of a majority in principal amount of all of the Debt

Securities then Outstanding (in the case of an Event of Default specified in clause (v) in “Events of Default,” above) may, on behalf of all such Holders, waive any past default under the Indenture with respect to Debt Securities of that series except a default in the payment of the principal of, or premium, if any, or interest, if any, on any such Debt Security and except a default in respect of a covenant or provision the modification or amendment of which would require the consent of the Holder of each outstanding Debt Security affected thereby.

Merger, Consolidation, or Sale of Assets

The Company shall not consolidate with or merge with or into any other corporation or transfer all or substantially all of its property and assets as an entirety to any Person, unless (i) either the Company shall be the continuing Person, or the Person (if other than the Company) formed by such consolidation or into which the Company is merged or to which all or substantially all of the properties and assets of the Company as an entirety are transferred is a corporation organized and existing under the laws of the United States or any State thereof or the District of Columbia which expressly assumes all of the obligations of the Company under each series of Debt Securities and the Indenture with respect to each such series and (ii) immediately before and immediately after giving effect to such transaction, no Event of Default and no event which, after notice or passage of time or both, would become an Event of Default shall have occurred and be continuing. Notwithstanding the foregoing, any Subsidiary may consolidate with, merge with or into or transfer all or part of its properties and assets to the Company or any other Subsidiary or Subsidiaries.

Limitation on Liens

The Indenture will provide that with respect to each series of Senior Debt Securities, unless otherwise set forth in the related Prospectus Supplement, the Company will not, and will not permit any of its Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien upon any of its property, assets or revenues, whether now owned or hereafter acquired, except for: (i) Liens for taxes not yet due or which are being contested in good faith by appropriate proceedings; provided that adequate reserves with respect thereto are maintained on the books of the Company or its Subsidiaries, as the case may be, in conformity with GAAP; (ii) carriers’, warehousemen’s, mechanics’, materialmen’s, repairmen’s or other like Liens arising in the ordinary course of business that are not overdue for a period of more than 60 days or which are being contested in good faith by appropriate proceedings; (iii) pledges or deposits in connection with workers’ compensation, unemployment insurance and other social security legislation and deposits securing liability to insurance carriers under insurance or self-insurance arrangements; (iv) deposits to secure the performance of bids, trade contracts (other than for borrowed money), leases, statutory obligations, surety and appeal bonds, performance bonds and other obligations of a like nature incurred in the ordinary course of business; (v) easements, rights-of-way, restrictions and other similar encumbrances incurred in the ordinary course of business which, in the aggregate, are not substantial in amount and which do not in any case materially detract from the value of the property subject thereto or materially interfere with the ordinary conduct of the business of the Company or such Subsidiary; (vi) Liens in existence on the date of the first issuance by the Company of Senior Debt Securities issued pursuant to the Indenture; provided that no such Lien is spread to cover any additional property after such date and that the amount of Debt secured thereby is not increased; (vii) Liens securing Debt of the Company and its Subsidiaries incurred to finance the acquisition of fixed or capital assets; provided that (A) such Liens will be created substantially simultaneously with the acquisition of such fixed or capital assets, (B) such Liens do not at any time encumber any property other than the property financed by such Debt and (C) the amount of Debt secured thereby is not increased; (viii) Liens on the property or assets of a corporation that becomes a Subsidiary after the date hereof; provided that (A) such Liens existed at the time such corporation became a Subsidiary and were not created in anticipation

thereof, (B) any such Lien is not spread to cover any property or assets or such corporation after the time such corporation becomes a Subsidiary, and (C) the amount of Debt secured thereby is not increased; and (ix) Liens (not otherwise permitted hereunder) (A) which secure obligations not exceeding the greater of $100.0 million or 15% of Consolidated Net Worth of the Company, in each case in aggregate amount at any time outstanding, or (B) with respect to which the Company effectively provides that the Senior Debt Securities outstanding hereunder are secured equally and ratably with (or, at the option of the Company, prior to) the Debt secured by such Lien.

Defeasance

If so specified in the Prospectus Supplement with respect to Debt Securities of any series, the Company at its option, (i) will be discharged from any and all obligations in respect of the Debt Securities of such series (except for certain obligations to register the transfer or exchange of Debt Securities of such series, replace stolen, lost or mutilated Debt Securities of such series, maintain Paying Agencies, and hold money for payment in trust) or (ii) will not be subject to certain specified covenants with respect to the Debt Securities of such series as set forth in the related Prospectus Supplement, in each case if the Company deposits with the Trustee, in trust, money or Government Obligations which through the payment of interest thereon and principal thereof in accordance with their terms will provide money in an amount sufficient to pay all the principal (including any mandatory sinking fund payments) of, and interest on, the Outstanding Debt Securities of such series on the dates such payments are due in accordance with the terms of such Debt Securities. To exercise any such option, the Company is required to deliver to the Trustee an Opinion of Counsel to the effect that the deposit and related defeasance would not cause the Holders of the Debt Securities of such series to recognize income, gain or loss for federal income tax purposes and, in the case of a discharge pursuant to clause (i), either a ruling to such effect received from or published by the U.S. Internal Revenue Service or an opinion that there has been a change in applicable federal income tax law to such effect. The Company is required to deliver to the Trustee an Officer’s Certificate stating that no Event of Default with respect to the Debt Securities of such series has occurred and is continuing.

Conversion Rights and Exchange Rights

The terms and conditions, if any, upon which any of the Debt Securities are convertible into or exchangeable for Common Stock or other securities or property of the Company will be set forth in the related Prospectus Supplement. Such terms shall include the conversion or exchange price (or manner of calculation thereof), the exchange or conversion period, provisions as to whether conversion or exchange is mandatory at the option of the Holder or at the option of the Company, and may include provisions pursuant to which the number of shares, other securities or property of the Company to be received by the Holders of Debt Securities would be calculated. The conversion or exchange price of any Debt Securities of any series that is convertible into Common Stock, Preferred Stock or Depositary Shares of the Company may be adjusted for any stock dividends, stock splits, reclassification, combinations or similar transactions, as set forth in the applicable Prospectus Supplement.

Subordination

Certain provisions of the Indenture relating to the subordination of the Subordinated Debt Securities are summarized below. The extent to which a particular series of Subordinated Debt Securities is subordinated to other indebtedness of the Company will be set forth in the Prospectus Supplement for that series and the Indenture may be modified by a supplemental indenture to reflect such subordination provisions. The particular terms of subordination of an

issue of Subordinated Debt Securities may supersede the general provisions of the Indenture summarized below.

Upon any distribution to creditors of the Company in a liquidation, dissolution or reorganization, payment of the principal of, premium, if any, and interest, if any, on the Subordinated Debt Securities will be subordinated to the extent provided in the Indenture in right of payment to the prior payment in full of all Senior Indebtedness, but the obligation of the Company to make payment of the principal of and premium, if any, and interest, if any, on the Subordinated Debt Securities will not otherwise be affected. Except as provided in a Prospectus Supplement and the related supplemental indenture, if any, no payment of principal or interest may be made on the Subordinated Debt Securities at any time if a default on Senior Indebtedness exists that permits the holders of such Senior Indebtedness to accelerate its maturity and the default is the subject of judicial proceedings or the Company has received notice of such default. Such supplemental indenture may also provide that Subordinated Debt Securities issued thereunder are subordinated and junior in right of payment to the prior payment in full of future senior subordinated debt securities, if any. After all Senior Indebtedness is paid in full and until the Subordinated Debt Securities are paid in full, Holders of the Subordinated Debt Securities will be subrogated to the rights of holders of Senior Indebtedness to the extent that distributions otherwise payable to such Holders have been applied to the payment of Senior Indebtedness. By reason of such subordination, in the event of any distribution of assets upon insolvency, certain general creditors of the Company may recover more, ratably, than holders of Subordinated Debt Securities.

The Trustee

The Indenture provides 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 such rights and powers vested in it under the Indenture and use the same degree of care and skill in its exercise as a prudent person would exercise under the circumstances in the conduct of such person’s own affairs.

The Indenture and the provisions of the Trust Indenture Act incorporated by reference therein contain limitations on the rights of the Trustee, should it become a creditor of the Company, 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 the Company or any Affiliate; provided, however, that if such Trustee acquires any conflicting interest (as defined in the Indenture or in the Trust Indenture Act), it must eliminate such conflict or resign.

No Personal Liability of Officers, Directors, Employees or Stockholders

No director, officer, employee or stockholder, as such, of the Company or any of its affiliates will have any personal liability in respect of the obligations of the Company under the Indenture or the Debt Securities by reason of his, her or its status as such.

Applicable Law

The Indenture is, and the Debt Securities offered hereby will be, governed by and construed in accordance with the laws of the State of New York.

DESCRIPTION OF PREFERRED STOCK

The following description of the terms of the Preferred Stock sets forth certain general terms and provisions of any series of Preferred Stock to which any Prospectus Supplement may relate. Particular terms of the Preferred Stock offered by any Prospectus Supplement and the

extent, if any, to which such general provisions may apply to any series of Preferred Stock so offered will be described in the Prospectus Supplement relating to such Preferred Stock. This description does not purport to be complete and is subject to and qualified in its entirety by reference to the provisions of the Second Restated Certificate of Incorporation of the Company as amended (the “Charter”), and the Certificate of Designation (the “Certificate of Designation”) relating to a particular series of Preferred Stock which will be in the form filed or incorporated by reference in the Registration Statement of which this Prospectus is a part at or prior to the time of the issuance of such series of Preferred Stock.

General

Under the Charter and the Restated By-laws of the Company (the “By-laws”), which are filed as exhibits to the Registration Statement of which this Prospectus is a part, the board of directors of the Company (the “Board of Directors”) is authorized without further shareholder action to adopt resolutions providing for the issuance of up to 50,000,000 shares of Preferred Stock, in one or more series, and to fix by resolution any of the powers, designations, preferences and relative dividend participation, option or other rights thereof, including dividend rights, conversion rights, voting rights, redemption terms and liquidation preferences, and the number of shares constituting each such series. Preferred Stock, upon issuance against full payment of the purchase price therefor, will be fully paid and nonassessable. As of the date of this Prospectus, the Company had no shares of Preferred Stock outstanding.

The Prospectus Supplement relating to a particular series of Preferred Stock offered will describe the specific terms, including, where applicable: (i) the title, designation, number of shares and stated value of such Preferred Stock; (ii) the price at which such Preferred Stock will be issued; (iii) the dividend rates, if any (or method of calculation), whether such rate is fixed or variable or both, and the dates on which dividends will be payable, whether such dividends will be cumulative or noncumulative and, if cumulative, the dates from which dividends shall commence to cumulate; (iv) the dates on which the Preferred Stock will be subject to redemption and the applicable redemption prices; (v) any redemption or sinking fund provisions; (vi) the convertibility or exchangeability of such Preferred Stock; (vii) if other than United States dollars, the currency or currencies (including composite currencies) in which such Preferred Stock is denominated and/or in which payments will or may be payable; (viii) the method by which amounts in respect of such Preferred Stock may be calculated and any commodities, currencies or indices, or the value, rate or price relevant to such calculation; (ix) the place where dividends and other payments on the Preferred Stock are payable and the identity of the transfer agent, registrar and dividend disbursement agent for the Preferred Stock; (x) any listing of such Preferred Stock on any securities exchange; and (xi) any additional dividend, liquidation, redemption, sinking fund, voting and other rights, preferences, privileges, limitations and restrictions.

The federal income tax consequences and special considerations applicable to any such series of Preferred Stock will be generally described in the Prospectus Supplement related thereto.

Rank

Unless otherwise specified in the Prospectus Supplement relating to a particular series of Preferred Stock, each series of Preferred Stock will rank pari passu as to dividends and liquidation rights in all respects with each other series of Preferred Stock.

Dividends

Holders of Preferred Stock of each series will be entitled to receive cash dividends, when and as declared by the Board of Directors out of assets of the Company legally available for

payment, at such rates and on such dates as will be set forth in the Prospectus Supplement relating to such series of Preferred Stock. Each dividend will be payable to holders of record as they appear on the stock books of the Company on the record dates fixed by the Board of Directors or a duly authorized committee thereof. Different series of the Preferred Stock may be entitled to dividends at different rates or based upon different methods of determination. Such rates may be fixed or variable or both. Dividends on any series of the Preferred Stock may be cumulative or noncumulative as provided in the Prospectus Supplement relating thereto. Except as provided in the related Prospectus Supplement, no series of Preferred Stock will be entitled to participate in the Company’s earnings or assets.

Liquidation Rights

Unless otherwise stated in the related Prospectus Supplement, in the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company, holders of each series of Preferred Stock will be entitled to receive out of assets of the Company available for distribution to shareholders, before any distribution of assets is made to holders of the Common Stock or any other class of stock ranking junior to such series of Preferred Stock upon liquidation, liquidating distributions in an amount set forth in the Prospectus Supplement related to such series of Preferred Stock, plus an amount equal to all accrued and unpaid dividends up to the date fixed for distribution for the current dividend period and, if such series of the Preferred Stock is cumulative, for all dividend periods prior thereto, all as set forth in the Prospectus Supplement with respect to such series of Preferred Stock. If, upon any voluntary or involuntary liquidation, dissolution or winding up of the Company, amounts payable with respect to a series of Preferred Stock and any other shares of capital stock of the Company ranking pari passu as to any distribution with such series of Preferred Stock are not paid in full, holders of such series of Preferred Stock and of such other shares will share ratably in any such distribution of assets of the Company in proportion to the full respective preferential amounts to which they are entitled. After payment in full of the liquidating distribution to which they are entitled, holders of Preferred Stock will not be entitled to any further participation in any distribution of assets by the Company.

Neither the sale, conveyance, exchange or transfer of all or substantially all of the property and assets of the Company, the consolidation or merger of the Company with or into any other corporation, nor the merger or consolidation of any other corporation into or with the Company, will be deemed to be a liquidation, dissolution or winding up of the Company.

Redemption and Sinking Fund

The terms, if any, on which shares of a series of Preferred Stock may be subject to optional or mandatory redemption, in whole or in part, or may have the benefit of a sinking fund, will be set forth in the Prospectus Supplement relating to such series.

Voting Rights

Except as indicated below or in the applicable Prospectus Supplement, or except as expressly required by applicable law, holders of Preferred Stock issued pursuant to this Prospectus and any related Prospectus Supplement will not be entitled to vote.

Conversion and Exchange Rights

The terms, if any, on which shares of any series of Preferred Stock are convertible or exchangeable will be set forth in the Prospectus Supplement relating thereto. The Prospectus Supplement will describe the securities or rights into which such shares of Preferred Stock are convertible or exchangeable (which may include other Preferred Stock, Debt Securities, Depositary Shares, Common Stock or other securities or rights of the Company (including rights

to receive payment in cash or securities based on the value, rate or price of one or more specified commodities, currencies or indices) or securities of other issuers or a combination of the foregoing), and the terms and conditions upon which such conversions or exchanges will be effected including the initial conversion or exchange prices or rules, the conversion or exchange period and any other related provisions. Such terms may include provisions for conversion or exchange, either mandatory, at the option of the holder, or at the option of the Company, in which case the consideration to be received by holders of such series of Preferred Stock would be calculated as of a time and in the manner stated in such Prospectus Supplement.

Transfer Agent and Registrar

The transfer agent, registrar and dividend disbursement agent for each series of Preferred Stock will be designated in the related Prospectus Supplement.

DESCRIPTION OF DEPOSITARY SHARES

The following description of the terms of the Depository Shares sets forth certain general terms and provisions of Depositary Shares to which any Prospectus Supplement may relate. Particular terms of the Depositary Shares offered by any Prospectus Supplement, and the related Deposit Agreement and Depositary Receipt, and the extent, if any, to which such general provisions may apply to such Deposit Agreement, Depositary Shares and Depositary Receipt, will be described in the Prospectus Supplement relating to such Depositary Shares. This description does not purport to be complete and is subject to, and qualified in its entirety by reference to, the provisions of the applicable Deposit Agreement, which will be in the form filed or incorporated by reference in the Registration Statement of which this Prospectus is a part at or prior to the time of the issuance of such Depositary Shares, as well as the Charter or any Certificate of Designation describing the applicable series of Preferred Stock.

General

The Company may, at its option, elect to offer fractional interests in shares of a series of Preferred Stock as Depositary Shares, rather than full shares of Preferred Stock. In such event, receipts (“Depositary Receipts”) for such Depositary Shares will be issued by the Company, each of which will represent a fraction of a share of a particular class or series of Preferred Stock, as described in the related Prospectus Supplement.

Shares of any series of Preferred Stock represented by Depositary Shares will be deposited under a separate deposit agreement (a “Deposit Agreement”), between the Company and a bank or trust company selected by the Company having its principal office in the United States and having a combined capital and surplus of at least $50 million (a “Preferred Stock Depositary”). The Prospectus Supplement relating to a series of Depositary Shares will set forth the name and address of the Depositary with respect to such Depositary Shares. Subject to the terms of the Deposit Agreement, each owner of a Depositary Share will be entitled, in proportion to the applicable fraction of a share of Preferred Stock represented by such Depositary Share, to all of the rights, preferences and privileges of the Preferred Stock represented thereby (including dividend, voting, conversion, exchange, redemption, and liquidation rights, if any).

Depositary Shares will be evidenced by Depositary Receipts issued pursuant to the applicable Deposit Agreement. Depositary Receipts will be distributed to those persons purchasing the fractional interests in shares of Preferred Stock as described in the applicable Prospectus Supplement.

Dividends and Other Distributions

The Preferred Stock Depositary will distribute all cash dividends or other cash distributions received in respect of a series of Preferred Stock to the record holders of Depositary Receipts relating to such Preferred Stock in proportion, insofar as possible, to the number of such Depositary Receipts owned by such holders on the relevant record date (subject to certain obligations of holders to file proofs, certificates and other information and to pay certain charges and expenses to such Preferred Stock Depositary). The Preferred Stock Depositary will distribute only such amount, however, as can be distributed without attributing to any holder of Depositary Shares a fraction of one cent, and the balance not so distributed will be held by the Preferred Stock Depositary and added to and treated as part of the next sum received by such Preferred Stock Depositary for distribution to record holders of Depositary Shares then outstanding.

In the event of a distribution other than in cash, the Preferred Stock Depositary will distribute property received by it to the record holders of Depositary Shares entitled thereto, in proportion to the number of such Depositary Shares owned by such holders, unless the Preferred Stock Depositary determines that it is not feasible to make such distribution, in which case the Preferred Stock Depositary may, with the approval of the Company, adopt such method as it deems equitable and practicable to effect such distribution, including the public or private sale of such property and distribution of the net proceeds from such sale to such holders.

The amount so distributed to record holders of Depositary Receipts in any of the foregoing cases will be reduced by any amount required to be withheld by the Company or the Preferred Stock Depositary on account of taxes.

The Deposit Agreement will also contain provisions relating to the manner in which any subscription or similar rights offered by the Company to holders of the Preferred Stock will be made available to holders of Depositary Shares.

Redemption of Depositary Shares

If a series of Preferred Stock represented by Depositary Shares is subject to redemption, the Depositary Shares will be redeemed from the proceeds received by the Preferred Stock Depositary resulting from redemption, in whole or in part, of such class or series of Preferred Stock held by the Preferred Stock Depositary. The redemption price per Depositary Share will be equal to the applicable fraction of the redemption price and other amounts per share, if any, payable in respect of such class or series of Preferred Stock. Whenever the Company redeems Preferred Stock held by the Preferred Stock Depositary, the Preferred Stock Depositary will redeem as of the same redemption date the number of Depositary Shares representing shares of Preferred Stock so redeemed. If fewer than all of the Depositary Shares are to be redeemed, the Depositary Shares to be redeemed will be selected by lot or pro rata as may be determined to be equitable by the Preferred Stock Depositary.

After the date fixed for redemption, the Depositary Shares so called for redemption will no longer be deemed to be outstanding and all rights of the holders of the Depositary Shares will cease, except the right to receive the redemption price upon such redemption. Any funds deposited by the Company with the Preferred Stock Depositary for any Depositary Shares which the holders thereof fail to redeem shall be returned to the Company after a period of two years from the date such funds are so deposited.

Voting the Preferred Stock

Upon receipt of notice of any meeting at which the holders of a class or series of Preferred Stock are entitled to vote, the Preferred Stock Depositary will mail the information contained

in such notice of meeting to record holders of the Depositary Receipts evidencing the Depositary Shares of such class or series of Preferred Stock. Each record holder of such Depositary Receipts on the record date (which will be the same date as the record date for the related class or series of Preferred Stock) will be entitled to instruct the Preferred Stock Depositary as to the exercise of the voting rights pertaining to the amount of Preferred Stock represented by such holder’s Depositary Shares. The Preferred Stock Depositary will endeavor, insofar as practicable, to vote the number of shares of Preferred Stock represented by such Depositary Shares in accordance with such instructions, and the Company will agree to take all reasonable action which may be deemed necessary by the Preferred Stock Depositary in order to enable the Preferred Stock Depositary to do so. The Preferred Stock Depositary will abstain from voting the Preferred Stock to the extent it does not receive specific instructions from the holder of Depositary Shares representing such shares of Preferred Stock. The Preferred Stock Depositary will not be responsible for any failure to carry out any instruction to vote, or for the manner or effect of any such vote made, as long as any such action or non-action is taken in good faith and does not result from the negligence or willful misconduct of the Preferred Stock Depositary.

Liquidation Preference

In the event of the liquidation, dissolution or winding up of the Company, whether voluntary or involuntary, holders of each Depositary Receipt will be entitled to the fraction of the liquidation preference accorded each share of related Preferred Stock as set forth in the related Prospectus Supplement.

Conversion and Exchange of Preferred Stock

If any series of Preferred Stock underlying the Depositary Shares is subject to provisions relating to its conversion or exchange, as set forth in the applicable Prospectus Supplement relating thereto, each record holder of Depositary Receipts will have the right or obligation to convert or exchange the Depositary Shares represented by such Depositary Receipts pursuant to the terms thereof.

Amendment and Termination of the Deposit Agreement

The form of Depositary Receipt evidencing the Depositary Shares and any provision of the Deposit Agreement may be amended at any time by agreement between the Company and the Preferred Stock Depositary. However, amendments, if any, which materially and adversely alter the rights of holders of Depositary Receipts or that would be materially and adversely inconsistent with the rights of holders of the underlying Preferred Stock, will be ineffective unless such amendment has been approved by holders of at least a majority of the Depositary Shares then outstanding under such Deposit Agreement. Every holder of outstanding Depositary Receipts at the time such amendment, if any, becomes effective will be deemed, by continuing to hold such Depositary Receipt, to consent to such amendment and to be bound by the applicable Deposit Agreement as amended thereby.

A Deposit Agreement may be terminated by the Company upon not less than 30 days’ prior written notice to the Preferred Stock Depositary if a majority of each class or series of Preferred Stock subject to such Deposit Agreement consents to such termination, whereupon the Preferred Stock Depositary will deliver or make available to each holder of Depositary Receipts, upon surrender of the Depositary Receipts held by such holder, such number of whole or fractional shares of Preferred Stock as are represented by the Depositary Shares evidenced by such Depositary Receipts, together with any other property held by the Preferred Stock Depositary with respect to such Depositary Receipts. Additionally, a Deposit Agreement will automatically terminate if (i) all outstanding Depositary Shares related thereto have been redeemed, (ii) there has been a final distribution in respect of the Preferred Stock underlying

such Depositary Shares in connection with any liquidation, dissolution or winding up of the Company and such distribution has been distributed to the holders of the related Depositary Receipts or (iii) each share of related Preferred Stock has been converted into capital stock of the Company not so represented by Depositary Shares.

Charges of Depositary

The Company will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. The Company will pay the Preferred Stock Depositary’s fees and charges in connection with the initial deposit of the Preferred Stock and initial issuance of Depositary Receipts and any redemption or conversion of the Preferred Stock. Holders of Depositary Receipts will pay all other transfer and other taxes, governmental charges and fees and charges of the Preferred Stock Depositary that are not expressly provided for in the Deposit Agreement.

Resignation and Removal of Depositary

A Preferred Stock Depositary may resign at any time by delivering to the Company notice of its election to do so, and the Company may at any time remove any Preferred Stock Depositary. Any such resignation or removal will take effect upon the appointment of a successor Depositary and such successor Depositary’s acceptance of the appointment. Such successor Depositary must be appointed within 60 days after delivery of the notice of resignation or removal and must be a bank or trust company having its principal office in the United States and having a combined capital and surplus of at least $50.0 million.

Miscellaneous

The Preferred Stock Depositary will forward all reports and communications from the Company which are delivered to the Preferred Stock Depositary and which the Company is required or otherwise determines to furnish to holders of the Preferred Stock.

Neither any Preferred Stock Depositary nor the Company will be liable if it is prevented or delayed by law or any circumstance beyond its control in performing its obligations under a Deposit Agreement. The obligations of the Company and any Preferred Stock Depositary under a Deposit Agreement will be limited to performing in good faith their duties thereunder (in the case of any action or inaction in the voting of a class or series of Preferred Stock represented by the Depositary Shares), gross negligence or willful misconduct excepted. The Company and any Preferred Stock Depositary will not be obligated under the Deposit Agreement to prosecute or defend any legal proceeding in respect of any Depositary Shares, Depositary Receipts or shares of any Preferred Stock represented thereby unless satisfactory indemnity is furnished. The Company and the Preferred Stock Depositary may rely upon written advice of counsel or accountants, or information provided by persons presenting shares of Preferred Stock for deposit, holders of Depositary Receipts or other persons believed to be competent to give such information and on documents believed to be genuine and to have been signed and presented by the proper party or parties.

DESCRIPTION OF COMMON STOCK

The following description of the terms of the Common Stock sets forth certain general provisions of the Common Stock as contained in the Charter and By-laws and is qualified in its entirety by reference to the Charter and By-laws.

General

The Company is currently authorized to issue up to of 600,000,000 shares of Common Stock. As of March 31, 1999, there were approximately 395.7 million shares of Common Stock outstanding. All outstanding shares of Common Stock are fully paid and nonassessable. The Common Stock is listed on the NYSE under the symbol “BSX.”

Holders of Common Stock have no preemptive, subscription, redemption or conversion rights and the Common Stock is not subject to redemption. The rights, preferences and privileges of holders of Common Stock are subject to, and may be adversely affected by, the rights of holders of any series of Preferred Stock, whether currently outstanding or designated and issued in the future. See “Description of Preferred Stock.”

Dividends

Subject to the preferences of holders of Preferred Stock, holders of Common Stock are entitled to dividends and other distributions when, as and if declared by the Board of Directors out of funds legally available therefor and shall share equally on a per share basis in all such dividends and other distributions.

Voting Rights

Except as otherwise provided by law or by the designation of the preferences, limitations and relative rights of any series of Preferred Stock, the voting power of the Company is held by holders of the Common Stock. Each holder of Common Stock is entitled to one vote for each share held. Holders of Common Stock are not entitled to cumulative voting rights and, therefore, holders of a plurality of shares voting in the election of directors may elect the entire class of the Board of Directors standing for election at a shareholders’ meeting at which a quorum is present. In that event, holders of the remaining shares of Common Stock would not be able to elect any director to the Board of Directors. The Company’s Charter requires that the Board of Directors be staggered, consisting of three classes of directors which are as nearly equal in number as possible.

Liquidation and Dissolution

Except as otherwise provided by the designation of the preferences, limitations and relative rights of any series of Preferred Stock, in the event of any liquidation, dissolution, or winding up of the Company, whether voluntary or involuntary, after payment has been made to holders of each series of Preferred Stock of the full amount to which they are entitled, holders of shares of Common Stock will be entitled to share, ratably according to the number of shares of Common Stock held by them, in all remaining assets available for distribution to holders of the Common Stock.

Certain Provisions of Delaware Law, the Charter and the By-laws

The Company is subject to the provisions of the General Corporate Law of Delaware. Section 203 of the General Corporate Law of Delaware 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 combinations are approved in a prescribed manner. A “business combination” includes mergers, assets sales, and other transactions resulting in a financial benefit to the interested stockholder. Subject to certain exceptions, an “interested stockholder” is a person who, together with affiliates owns, or within three years did own, 15% or more of the corporation’s voting stock.

As permitted by the General Corporation Law of Delaware, the Company’s Charter provides that Directors of the Company will not be personally liable to the Company or its stockholders for monetary damages for breach of fiduciary duty as a Director, except in certain circumstances involving wrongful acts, such as the breach of a directors duty of loyalty or acts or omissions which involve intentional misconduct or a knowing violation of law. The Company’s Charter and By-laws also contain provisions requiring the Company to indemnify the Company Directors and officers to the fullest extent permitted by the General Corporate Law of Delaware. In addition, the Company has entered into indemnification agreements with each of its Directors and executive officers. These agreements provide rights of indemnification substantially similar to and in certain respects broader than those provided by the Charter and By-laws.

The Certificate and the By-laws provide that the Board of Directors be divided into three classes of Directors as nearly equal in size as possible, with staggered three year terms. The Charter provides that vacancies on the Board may only be filled by a majority of the Board then in office and further provides that Directors may only be removed by the affirmative vote of holders of at least 80% of the voting power of all the then outstanding shares of stock entitled to vote generally in the election of Directors.

The Charter provides that stockholder action can only be taken at an annual or special meeting of stockholders and that the business permitted to be conducted at any meeting of stockholders is limited to the business brought before the meeting by the Chairman of the Board or the President of the Company or at the request of a majority of the members of the Board. The Charter and By-laws provide that special meetings of stockholders can be called only by the Chairman of the Board of the Company or pursuant to a resolution approved by a majority of the total number of Directors which the Company would have if there were no vacancies on the Board. Stockholders are not permitted to call a special meeting or to require that the Board call a special meeting of stockholders.

The Charter prohibits the Company, with certain exceptions, from purchasing any shares of the Company’s stock from any person, entity or group that beneficially owns 5% or more of the Company’s voting stock at an above-market price, unless a majority of the Company’s disinterested stockholders approve the transaction. In addition, the Charter empowers the Board, when considering a tender offer or merger or acquisition proposal, to take into account factors in addition to potential economic benefits to stockholders and to consider constituencies other than stockholders.

The General Corporation Law of Delaware provides generally that the vote of a majority of shares entitled to vote is required to act on most matters and to amend a corporation’s certificate of incorporation. The Certificate and the By-laws contain provisions requiring the affirmative vote of the holders of at least 80% of the voting stock, voting together as a single class, to amend certain provisions of the Charter and the By-laws, including certain of the foregoing provisions. Such a supermajority vote would be in addition to any separate class vote that might in the future be required with respect to shares of Preferred Stock then outstanding.

The foregoing and other provisions of Delaware law and the Company’s Charter and By-laws could make more difficult the acquisition of the Company by means of a tender offer, a proxy contest or otherwise. These provisions may have the effect of delaying, deferring or preventing a change in control of the Company, may discourage bids for the Common Stock at a premium over the market price of the Common Stock and may adversely affect the market price of the Common Stock.

Transfer Agent

The transfer agent and registrar for the Common Stock is Boston Equiserve.

Each series of Warrants will be issued under a separate warrant agreement (each, a “Warrant Agreement”) to be entered into between the Company and a warrant agent (“Warrant Agent”). The Warrant Agent will act solely as an agent of the Company in connection with the Warrants of such series and will not assume any obligation or relationship of agency for or with holders or beneficial owners of Warrants.

The Warrant Agreement for a series of Warrants may be amended or supplemented without the consent of the holders of the Warrants issued thereunder to effect changes that are not inconsistent with the provisions of the Warrants and that do not adversely affect the interests of the holders of the Warrants.

DESCRIPTION OF STOCK PURCHASE CONTRACTS

AND STOCK PURCHASE UNITS

The following description of the terms of the Stock Purchase Contracts and Stock Purchase Units sets forth certain general terms and provisions of the Stock Purchase Contracts and/or Stock Purchase Units to which any Prospectus Supplement may relate. Particular terms of the Stock Purchase Contracts and/or Stock Purchase Units offered by any Prospectus Supplement and the extent, if any, to which such general provisions may apply to the Stock Purchase Contracts and/or Stock Purchase Units so offered will be described in the Prospectus Supplement relating to such Stock Purchase Contracts and/or Stock Purchase Units.

The Company may issue Stock Purchase Contracts, including contracts obligating holders to purchase from the Company, and the Company to sell to holders, a specified number of shares of Common Stock, Preferred Stock or Depositary Shares at a future date. The consideration per share of Common Stock, Preferred Stock or Depositary Shares may be fixed at the time that the Stock Purchase Contracts are issued or may be determined by reference to a specific formula set forth in the Stock Purchase Contracts. Any such formula may include anti-dilution provisions to adjust the number of shares issuable pursuant to such Stock Purchase Contract upon the occurrence of certain events. The Stock Purchase Contracts may be issued separately or as a part of units (“Stock Purchase Units”), consisting of a Stock Purchase Contract and Debt Securities, Trust Preferred Securities or debt obligations of third parties, including U.S. Treasury securities, in each case securing holders’ obligations to purchase Common Stock, Preferred Stock or Depositary Shares under the Stock Purchase Contracts. The Stock Purchase Contracts may require the Company to make periodic payments to holders of the Stock Purchase Units, or vice versa, and such payments may be unsecured or prefunded. The Stock Purchase Contracts may require holders to secure their obligations thereunder in a specified manner.

Each applicable Prospectus Supplement will describe the terms of any Stock Purchase Contracts or Stock Purchase Units. The description in the Prospectus Supplement will not purport to be complete and will be qualified in its entirety by reference to the Stock Purchase Contracts, and, if applicable, collateral arrangements and depositary arrangements, relating to such Stock Purchase Contracts or Stock Purchase Units.

DESCRIPTION OF TRUST PREFERRED SECURITIES

The following description of the terms of the Trust Preferred Securities sets forth certain general terms and provisions of the Trust Preferred Securities to which any Prospectus Supplement may relate. Particular terms of the Trust Preferred Securities offered by any Prospectus Supplement and the extent, if any, to which such general terms and provisions may apply to the Trust Preferred Securities so offered will be described in the Prospectus Supplement relating to such Trust Preferred Securities.

Each Trust may issue, from time to time, one or more series of Trust Preferred Securities having terms described in the Prospectus Supplement relating thereto. The Declaration authorizes the Regular Trustees of each Trust to issue one or more series of Trust Preferred Securities on behalf of the respective Trust. Each Declaration will be qualified as an indenture under the Trust Indenture Act. The Institutional Trustee for each Trust, an independent trustee, will act as indenture trustee for the Trust Preferred Securities to be issued by such Trust for purposes of compliance with the Trust Indenture Act.

The Trust Preferred Securities will have such terms, including with respect to distributions, redemption, voting, liquidation rights and such other preferred, deferred or other special rights or such restrictions as shall established by the Regular Trustees of the applicable Trust in accordance with the Declaration of such Trust or as shall be set forth in such Declaration or made part of such Declaration by the Trust Indenture Act.

Reference is made to the Prospectus Supplement relating to the Trust Preferred Securities of the applicable Trust for specific terms of such Trust Preferred Securities, including (i) the distinctive designation of such Trust Preferred Securities; (ii) the aggregate number of Trust Preferred Securities to be issued by such Trust; (iii) the annual distribution rate (or method of determining such rate) for such Trust Preferred Securities and the date or dates upon which such distributions will be payable; provided, however, that distributions on the Trust Preferred Securities shall, subject to any deferral provisions, and any provisions for payment of defaulted distributions, be payable on a periodic basis to holders of Trust Preferred Securities as of a record date in each period during which Trust Preferred Securities are outstanding; (iv) any right of such Trust to defer periodic distributions on such Trust Preferred Securities as a result of any interest deferral right exercised by the Company on the Subordinated Debt Securities held by such Trust; (v) whether distributions on such Trust Preferred Securities will be cumulative, and, in the case of Trust Preferred Securities having such cumulative distribution rights, the date or dates or the method of determining the date or dates from which distributions on such Trust Preferred Securities will be cumulative; (vi) the amount or amounts which will be paid out of the assets of such Trust to holders of Trust Preferred Securities upon voluntary or involuntary dissolution, winding-up or termination of such Trust; (vii) the obligation or option, if any, of such Trust to purchase or redeem Trust Preferred Securities and the price or prices at which, the period or periods within which, and the terms and conditions upon which, such Trust Preferred Securities will be purchased or redeemed, in whole or in part, pursuant to such obligation or option; (viii) the voting rights, if any, of such Trust Preferred Securities in addition to those required by law, including the number of votes per Trust Preferred Security and any requirement for the approval by holders of such Trust Preferred Securities as a condition to specified action or amendments to the applicable Declaration; (ix) the terms and conditions, if any, upon which the Subordinated Debt Securities may be distributed to holders of Trust Preferred Securities; (x) if applicable, any securities exchange upon which such Trust Preferred Securities shall be listed; (xi) whether such Trust Preferred Securities are convertible or exchangeable, and if so, the securities or rights into which such Trust Preferred Securities are convertible or exchangeable, and the terms and conditions upon which such conversions or exchanges will be effected; (xii) the method by which amounts payable in respect of such Trust Preferred Securities may be calculated and any commodities, currencies, currency units or composite currencies, or indices, or value, rate or price, relevant to such calculation; and (xiii) any other relevant rights, preferences, privileges, limitations or restrictions of such Trust Preferred Securities not inconsistent with the applicable Declaration or with applicable law.

All Trust Preferred Securities offered will be guaranteed by the Company to the extent set forth below under “Description of Trust Guarantee.” The Trust Guarantees of the Company, when taken together with the Company’s obligations under the Subordinated Debt Securities and the relevant supplemental indenture, and its obligations under each Declaration, including the Company’s obligations to pay costs, expenses, debts and liabilities of each Trust (other than with respect to the Trust Securities), will provide a full and unconditional guarantee, on a subordinated basis, of amounts due on the Trust Preferred Securities. The payment terms of the Trust Preferred Securities issued by a Trust will be the same as the Subordinated Debt Securities issued to such Trust by the Company. The Prospectus Supplement relating to any offering of Trust Preferred Securities will describe certain U.S. federal income tax considerations applicable thereto.

Trust Common Securities

In connection with the issuance of Trust Preferred Securities, a Trust will issue Trust Common Securities. Each Declaration authorizes the Regular Trustees to issue on behalf of a Trust one or more series of Trust Common Securities having such terms, including with respect to distributions, redemption, voting, liquidation rights or other restrictions as shall be

established by such Regular Trustees in accordance with such Declaration or as shall otherwise be set forth therein. The terms of Trust Common Securities of a Trust will be substantially identical to the terms of the related Trust Preferred Securities of such Trust, and such Trust Common Securities will rank pari passu, and payments will be made thereon pro rata, with such Trust Preferred Securities except that, upon an event of default under its Declaration, the rights of holders of such Trust Common Securities to payment in respect of distributions and payments upon liquidation, redemption and otherwise will be subordinated to the rights of holders of such Trust Preferred Securities. Except in certain limited circumstances, Trust Common Securities will also carry the right to vote to appoint, remove or replace any of the Capital Trustees of the applicable Trust. The Company will own directly or indirectly all of the Trust Common Securities of each of the Trusts.

DESCRIPTION OF TRUST GUARANTEE

The following description of the terms of the Trust Guarantees which will be executed and delivered by the Company for the benefit of holders from time to time of Trust Preferred Securities sets forth certain general terms and provisions of the Trust Guarantees to which any Prospectus Supplement may relate. This description does not purport to be complete and is subject to, and qualified in its entirety by reference to all of the provisions in each Trust Guarantee, which will be in the form filed with or incorporated by reference in the Registration Statement of which this Prospectus is a part at or prior to the time of issuance of Trust Preferred Securities, and those made part of the Trust Guarantee by the Trust Indenture Act, as in effect on the date of such Trust Guarantee, and to such Trust Preferred Securities.

General

Each Trust Guarantee will be qualified as an indenture under the Trust Indenture Act. Chase Manhattan Bank, an independent trustee, will act as indenture trustee under each Trust Guarantee (the “Guarantee Trustee”) for the purposes of compliance with the provisions of the Trust Indenture Act. Pursuant to each Trust Guarantee, unless otherwise specified in the applicable Prospectus Supplement, the Company will agree, to the extent set forth therein, to pay in full, on a subordinated basis, to holders of Trust Preferred Securities, the Trust Guarantee Payments (as defined herein) (except to the extent paid by the applicable Trust), as and when due, regardless of any defense, right of set-off or counterclaim which such Trust may have or assert. The following payments or distributions with respect to Trust Preferred Securities, to the extent not paid by or on behalf of the applicable Trust (the “Guarantee Payments”), will be subject to a Trust Guarantee (without duplication): (i) any accrued and unpaid distributions which are required to be paid on Trust Preferred Securities, to the extent the applicable Trust has funds available therefor; (ii) with respect to any Trust Preferred Securities called for redemption by a Trust, the redemption price (the “Redemption Price”) and all accrued and unpaid distributions to the date of redemption, to the extent such Trust has funds available therefor and (iii) upon a voluntary or involuntary dissolution, winding-up or termination of a Trust (other than in connection with the distribution of Subordinated Debt Securities to holders of Trust Preferred Securities or the redemption of all of the Trust Preferred Securities), the lesser of (a) the aggregate of the liquidation amount and all accrued and unpaid distributions on the Trust Preferred Securities to the date of payment, to the extent such Trust has funds available therefor, and (b) the amount of assets of such Trust remaining available for distribution to holders of Trust Preferred Securities in liquidation of such Trust. The Company’s obligation to make a Guarantee Payment may be satisfied by direct payment of the required amounts by the Company to holders of Trust Preferred Securities or by causing the applicable Trust to pay such amounts to such holders.

The Trust Guarantees will not apply to any payment of distributions except to the extent a Trust has funds available therefor. If the Company does not make interest or principal

payments on the Subordinated Debt Securities purchased by a Trust, such Trust will not have funds available for, and will not pay, distributions on Trust Preferred Securities.

The Company has also agreed separately to guarantee the obligations of each Trust with respect to Trust Common Securities (the “Common Securities Guarantee”) to the same extent as a Trust Guarantee, except that upon an Event of Default under a Declaration, holders of Trust Preferred Securities shall have priority over holders of Trust Common Securities with respect to distributions and payments on liquidation, redemption or otherwise.

Certain Covenants of the Company

Unless otherwise specified in the applicable Prospectus Supplement, in the applicable Trust Guarantee, the Company will covenant that, so long as any applicable Trust Preferred Securities remain outstanding, if there shall have occurred any event that would constitute an event of default under such Trust Guarantee or Declaration, then (a) the Company will not declare or pay any dividend on, make any distributions with respect to, or redeem, purchase, acquire or make a liquidation payment with respect to, any of its capital stock (other than (i) purchases or acquisitions of capital stock of the Company in satisfaction of the Company’s obligations under any employee benefit plans, systematic stock repurchase program, or in satisfaction of its obligations pursuant to any contract or security outstanding on the date of such event requiring the Company to purchase its capital stock, (ii) as a result of a reclassification of the Company’s capital stock or the exchange or conversion of one class or series of the Company’s capital stock for another class or series of the Company’s capital stock, (iii) the purchase of fractional interests in shares of the Company’s capital stock pursuant to the conversion or exchange provisions of such capital stock or the security being so converted or exchanged, (iv) dividends or distributions in capital stock of the Company (or rights to acquire capital stock) or repurchases or redemptions of capital stock solely from the issuance or exchange of capital stock, and (v) redemptions or repurchases of any rights outstanding under a shareholder rights plan), (b) the Company will not make any payment of interest, principal or premium, if any, on or repay, repurchase or redeem any of its debt securities which rank junior to the Subordinated Debt Securities and (c) the Company will not make any guarantee payments with respect to the foregoing (other than payments pursuant to a Trust Guarantee or a Common Securities Guarantee).

Modification of the Trust Guarantee; Assignment

Except with respect to any changes that do not adversely affect the rights of holders of Trust Preferred Securities (in which case no consent will be required), a Trust Guarantee may be amended only with the prior approval of holders of not less than a majority in liquidation amount of the outstanding Trust Preferred Securities issued by the applicable Trust. The manner of obtaining any such approval of holders of the Trust Preferred Securities will be set forth in the accompanying Prospectus Supplement. All guarantees and agreements contained in the Trust Guarantee will bind the successors, assigns, receivers, trustees and representatives of the Company and will inure to the benefit of holders of the applicable Trust Preferred Securities then outstanding.

Termination

A Trust Guarantee will terminate (a) upon full payment of the Redemption Price of all applicable Trust Preferred Securities then outstanding, (b) upon distribution of the Subordinated Debt Securities held by such Trust to the applicable holders of Trust Preferred Securities or (c) upon full payment of the amounts payable in accordance with the Declaration upon liquidation of a Trust. A Trust Guarantee will continue to be effective or will be reinstated, as the case may be, if at any time any holder of Trust Preferred Securities must restore payment of any sums paid to it under Trust Preferred Securities or a Trust Guarantee.

Events of Default

An event of default under a Trust Guarantee will occur upon the failure of the Company to perform any of its payment or other obligations thereunder.

Holders of a majority in liquidation amount of the Trust Preferred Securities issued by a Trust will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the applicable Guarantee Trustee or to direct the exercise of any trust or power conferred upon such Guarantee Trustee. If a Guarantee Trustee fails to enforce a Trust Guarantee, any record holder of Trust Preferred Securities may institute a legal proceeding directly against the Company to enforce such holder’s rights under such Trust Guarantee without first instituting a legal proceeding against the applicable Trust, such Guarantee Trustee or any other person or entity. Notwithstanding the foregoing, if the Company has failed to make a payment required under a Trust Guarantee, a record holder of Trust Preferred Securities may directly institute a proceeding against the Company for enforcement of such Trust Guarantee for such payment to the record holder of Trust Preferred Securities of the principal of or interest on the applicable Debt Securities on or after the respective due dates specified in the Debt Securities, and the amount of the payment will be based on the holder’s pro rata share of the amount due and owing on all Trust Preferred Securities issued by the applicable Trust. The Company waives any right or remedy to require that any action be brought first against each Trust or any other person or entity before proceeding directly against the Company.

Status of the Trust Guarantees

Each of the Trust Guarantees will constitute an unsecured obligation of the Company and will rank (i) subordinate and junior in right of payment to all other liabilities of the Company, except those liabilities of the Company made pari passu or subordinate by their terms; (ii) pari passu with most senior preferred or preference stock now or hereafter issued by the Company and with any guarantee now or hereafter entered by the Company in respect of any preferred or preference stock of any affiliate of the Company; and (iii) senior to the Common Stock of the Company. The terms of the Trust Preferred Securities provide that each holder of Trust Preferred Securities, by acceptance thereof, agrees to the subordination provisions and other terms of the Trust Guarantee relating thereto.

Each Trust Guarantee will constitute a guarantee of payment and not of collection (that is, the guaranteed party may institute a legal proceeding directly against the Company to enforce its rights under the guarantee without instituting a legal proceeding against any other person or entity).

Information Concerning the Guarantee Trustee

The Guarantee Trustee, prior to the occurrence of a default with respect to a Trust Guarantee, undertakes to perform only such duties as are specifically set forth in the applicable Trust Guarantee and, after default, will exercise the same degree of care as a prudent individual would exercise in the conduct of his or her own affairs. Subject to such provisions, the Guarantee Trustee is under no obligation to exercise any of the powers vested in it by a Trust Guarantee at the request of any holder of Trust Preferred Securities, unless offered reasonable indemnity against the costs, expenses and liabilities which might be incurred thereby. The foregoing will not relieve the Guarantee Trustee, upon the occurrence of an event of default under a Trust Guarantee, from exercising the rights and powers vested in it by such Trust Guarantee.

Applicable Law

The Trust Guarantees will be governed by and construed in accordance with the laws of the State of New York.

PLAN OF DISTRIBUTION

The Company may sell the Securities and the Trusts may sell the Trust Preferred Securities being offered hereby may be sold in any one or more of the following ways from time to time: (i) through agents; (ii) to or through underwriters; (iii) through dealers; and/or (iv) directly by the Company or, in the case of Trust Preferred Securities, by the Trusts, to purchasers.

Any such agent involved in the offer or sale of the Securities in respect of which this Prospectus is delivered will be named, and any commissions payable by the Company or by any Trust to such agent will be set forth, in the applicable Prospectus Supplement. Unless otherwise indicated in such Prospectus Supplement, any such agent will be acting on a reasonable best efforts basis for the period of its appointment (ordinarily five business days or less).

If underwriters are utilized in the sale of any Securities in respect of which this Prospectus is being delivered, such Securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at fixed public offering prices or at varying prices determined by the underwriters at the time of sale. Securities may be offered to the public either through underwriting syndicates represented by managing underwriters or directly by one or more underwriters. If any underwriter or underwriters are utilized in the sale of Securities, unless otherwise indicated in the applicable Prospectus Supplement, the underwriting agreement will provide that the obligations of the underwriters are subject to certain conditions precedent and that the underwriters with respect to a sale of such Securities will be obligated to purchase all such Securities if any are purchased.

The Company or any of the Trusts, as applicable, may grant to the underwriters options to purchase additional Securities, to cover over-allotments, if any, at the initial public offering price (with additional underwriting commissions or discounts), as may be set forth in the Prospectus Supplement relating thereto. If the Company or any such Trust, as applicable, grants any over-allotment option, the terms of such over-allotment option will be set forth in the Prospectus Supplement for such Securities.

If a dealer is utilized in the sale of the Securities in respect of which this Prospectus is delivered, the Company or any of the Trusts, as applicable, will sell such Securities to the dealer, as principal. The dealer may then resell such Securities to the public at varying prices to be determined by such dealer at the time of resale. Any such dealer may be deemed to be an

underwriter, as such term is defined in the Securities Act, of the Securities so offered and sold. The name of the dealer and the terms of the transaction will be set forth in the Prospectus Supplement relating thereto.

Offers to purchase Securities may be solicited directly by the Company or any of the Trusts, as applicable, and the sale thereof may be made by the Company or any of the Trusts directly to institutional investors or others, who may be deemed to be underwriters within the meaning of the Securities Act with respect to any resale thereof. The terms of any such sales will be described in the Prospectus Supplement relating thereto.

Securities may also be offered and sold, if so indicated in the applicable Prospectus Supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment pursuant to their terms, or otherwise, by one or more firms (“remarketing firms”), acting as principals for their own accounts or as agents for the Company or any of the Trusts, as applicable. Any remarketing firm will be identified and the terms of its agreement, if any, with the Company or any such Trust and its compensation will be described in the applicable Prospectus Supplement. Remarketing firms may be deemed to be underwriters, as that term is defined in the Securities Act, in connection with the Securities remarketed thereby.

If so indicated in the applicable Prospectus Supplement, the Company or any of the Trusts, as applicable, may authorize agents and underwriters to solicit offers by certain institutions to purchase Securities from the Company or any such Trust at the public offering price set forth in the applicable Prospectus Supplement pursuant to delayed delivery contracts providing for payment and delivery on the date or dates stated in the applicable Prospectus Supplement. Such delayed delivery contracts will be subject only to those conditions set forth in the applicable Prospectus Supplement. A commission indicated in the applicable Prospectus Supplement will be paid to underwriters and agents soliciting purchases of Securities pursuant to delayed delivery contracts accepted by the Company or any of the Trusts, as applicable.

Agents, underwriters, dealers and remarketing firms may be entitled under relevant agreements with the Company or any of the Trusts, as applicable, to indemnification by the Company or any such Trust against certain liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which such agents, underwriters, dealers and remarketing firms may be required to make in respect thereof.

Each series of Securities will be a new issue and, other than the Common Stock, which is listed on the New York Stock Exchange, will have no established trading market. The Company may elect to list any series of Securities on an exchange, and in the case of the Common Stock, on any additional exchange, but, unless otherwise specified in the applicable Prospectus Supplement, the Company shall not be obligated to do so. No assurance can be given as to the liquidity of the trading market for any of the Securities.

Agents, underwriters, dealers and remarketing firms may, engage in transactions with, or perform services for, the Company and its subsidiaries in the ordinary course of business.

The place and time of delivery for Securities will be set forth in the accompanying Prospectus Supplement for such Securities.
