THE COMPANY The Company (formerly IMCERA Group Inc.), a New York corporation, provides human and animal health care products and specialty chemicals worldwide by means of its three technology-based operating subsidiaries: Mallinckrodt Chemical, Inc. Mallinckrodt Chemical is a producer of high-quality specialty pharmaceutical chemicals and highly selected specialty industrial chemicals and catalysts. Mallinckrodt Chemical is also a joint venture partner with Hercules Incorporated in a worldwide flavors business, Tastemaker, which develops and sells products for the beverage, sweet goods, savory and confection markets. Mallinckrodt Medical, Inc. Mallinckrodt Medical provides technologically advanced products and services to five medical specialties: radiology; cardiology; nuclear medicine; anesthesiology; and critical care. Mallinckrodt Veterinary, Inc. Mallinckrodt Veterinary (formerly Pitman-Moore, Inc.) is one of the world's largest branded animal health and nutrition companies with approximately 1,000 products sold in more than 100 countries. The Company was founded in 1909 and was primarily a producer and manufacturer of fertilizers and other commodity chemicals. The Company undertook a major restructuring of its businesses beginning with the February 1986 acquisition of the Mallinckrodt Medical and Mallinckrodt Chemical businesses. In October 1986, the Company sold its industrial products and oil and gas divisions. Beginning in February 1988, the Company began reducing its interest in its fertilizer business, which is now an independent publicly-held company named IMC Global Inc. ("IMC Global") (formerly IMC Fertilizer Group, Inc.), and the Company completed the disposition of its remaining equity interest in IMC Global on July 2, 1991. Since 1986, the Company has expanded its animal health business through a series of acquisitions, including the acquisition of the Pitman-Moore business in 1987 and the acquisition of Coopers Animal Health Group in 1989. In June 1993, the Company announced the details of a restructuring program which resulted in a charge of $242 million after taxes, most of which was for actions taken at Mallinckrodt Veterinary. In June 1994, the Company announced the details of a further restructuring program which resulted in a charge of $59 million after taxes, most of which relates to Mallinckrodt Medical. In March 1994, the Company changed its name from IMCERA Group Inc. to Mallinckrodt Group Inc. and moved its headquarters from Northbrook, Illinois to St. Louis, Missouri. The Company's corporate headquarters is located at 7733 Forsyth Boulevard, St. Louis, MO 63105-1820, and its telephone number is: (314) 854-5200. USE OF PROCEEDS The net proceeds from the sale of the Offered Securities will be added to the general funds of the Company and will be used for general corporate purposes, except as otherwise noted in any Prospectus Supplement. Pending such a use, some portion of such funds may be invested in short-term marketable securities. RATIO OF EARNINGS TO FIXED CHARGES SIX MONTHS ENDED DECEMBER 31, YEARS ENDED JUNE 30, 1994 1993 1994 1993 1992 1991 1990 Ratio of earnings to fixed charges . . . . . 4.9 5.3 4.0 (1) 4.9 4.0 2.6 ___________ (1) Earnings were inadequate to cover fixed charges for the year ended June 30, 1993. The coverage deficiency was approximately $140 million. The ratio of earnings to fixed charges is based on earnings from continuing operations and has been computed on a total enterprise basis. Earnings represent income from continuing operations before income taxes and fixed charges, net of capitalized interest. Fixed charges consist of interest expense before reduction for capitalized interest, one-third of rental expense (net of rental income from subleased properties), which is considered to be representative of the interest factors in the leases, and the Company's proportionate share of interest expense of 50%-owned entities accounted for by the equity method before reduction for capitalized interest, and amortization of debt discount and expenses. DESCRIPTION OF THE SECURITIES The following description of the Debt Securities sets forth certain general terms and provisions of the Offered Securities to which any Prospectus Supplement may relate. The Debt Securities are to be issued under an Indenture dated as of March 15, 1985, as amended and restated as of February 15, 1995, and as may be further amended and supplemented (the "Indenture"), between the Company and First Trust of New York, National Association, as trustee (the "Trustee"), a copy of which is filed as an exhibit to the Registration Statement. The particular terms of the Offered Securities and the extent, if any, to which such general provisions may apply to the Offered Securities will be described in the Prospectus Supplement relating to such Offered Securities. The following summaries of certain provisions of the Indenture do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all the provisions of the Indenture, including the definition therein of certain terms. Wherever particular articles, sections or defined terms of the Indenture are referred to, it is intended that such articles, sections or defined terms shall be incorporated herein by reference. GENERAL The Indenture does not limit the aggregate principal amount of debentures, notes or other evidences of indebtedness which may be issued thereunder (such debentures, notes or other evidences of indebtedness issued under the Indenture being herein referred to as the "Securities"). The Indenture provides that Securities may be issued from time to time in one or more series. The Securities will be unsecured obligations ranking equally with each other and with other unsecured and unsubordinated indebtedness of the Company. The Prospectus Supplement relating to the particular Securities offered thereby will describe the following terms of the Offered Securities: (1) the title of the Offered Securities; (2) any limit on the aggregate principal amount of the Offered Securities; (3) the record date for determining the persons to whom any interest on any Offered Securities of the series will be payable; (4) the date or dates on which the principal of the Offered Securities will be payable; (5) the rate or rates (or formula for determining such rates) at which the Offered Securities of the series will bear interest, if any, the date or dates from which such interest will accrue, the interest payment dates on which such interest will be payable and the record dates for the determination of Holders to whom interest is payable; (6) whether the interest rate or interest rate formula for Offered Securities of the series may be reset at the option of the Company or otherwise, and the date or dates on which such interest rate or interest rate formula may be reset; (7) the place or places where the principal and interest on the Offered Securities of the series will be payable and the place or places where the Offered Securities may be surrendered for registration or transfer or exchange; (8) the date, if any, after which the Offered Securities may, pursuant to any optional or mandatory redemption provisions, be redeemed, in whole or in part, and the other detailed terms and provisions of any such optional or mandatory redemption provisions; (9) any mandatory or optional sinking fund or analogous provisions; (10) the currency or the composite currency in which the Offered Securities are denominated (the "Specified Currency"); (11) the currency or currencies of payment of principal of and any premium and interest on the Offered Securities if other than the Specified Currency; (12) any index used to determine the amount of payments of principal of and any premium and interest on the Offered Securities; (13) any additional covenants applicable to the Offered Securities; and (14) any other terms of the Offered Securities (which terms will not be inconsistent with the provisions of the Indenture). Unless otherwise indicated in the Prospectus Supplement, principal of (and premium, if any) and interest, if any, on the Offered Securities will be payable, and transfers of the Offered Securities will be registrable, at the Corporate Trust Office of the Trustee (currently located at 100 Wall Street, Suite 1600, New York, New York 10005), provided that at the option of the Company payment of interest may be made by check mailed to the address of the person entitled thereto as it appears in the Security Register. (Sections 3.01, 3.03, 3.06 and 5.02) Unless otherwise indicated in the Prospectus Supplement, the Offered Securities will be issued only in fully registered form without coupons in denominations of 1,000 units of the Specified Currency or any integral multiple thereof. (Section 3.02) No service charge will be made for any registration of transfer or exchange of Offered Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. (Section 3.06) If any of the Offered Securities are denominated in a Specified Currency other than U.S. dollars or if the principal, premium and/or interest with respect to any series of Offered Securities is payable in a Specified Currency other than U.S. Dollars, the restrictions, elections, general tax considerations, specific terms and other information with respect to such issue of Offered Securities related to such Specified Currency will be set forth in the applicable Prospectus Supplement. The Company shall not be required to (i) issue, register the transfer of, or exchange Securities of any series during the period from 15 days prior to the mailing of notice of redemption of Securities of that series to the date of such mailing or (ii) register the transfer of or exchange any Security so selected for redemption, except the unredeemed portion of any Security being redeemed in part. (Section 3.06) Securities may be issued under the Indenture as Original Issue Discount Securities to be sold at a substantial discount below their principal amount. Federal income tax and other considerations applicable to any Security that is issued with "original issue discount" for Federal income tax purposes (which may include an Original Issue Discount Security) will be described in the Prospectus Supplement relating thereto. The Prospectus Supplement may indicate terms for redemption at the option of a Holder. Unless otherwise indicated in the Prospectus Supplement, the covenants contained in the Indenture and the Offered Securities would not provide for redemption at the option of a Holder nor afford Holders protection in the event of a highly leveraged or other transaction that may adversely affect Holders. CERTAIN DEFINITIONS The following terms are defined substantially as follows in Section 1.01 of the Indenture and are used herein as so defined. Consolidated Net Tangible Assets. (a) The total amount of assets (less applicable reserves and other properly deductible items) after deducting therefrom (i) all liabilities and liability items, except for indebtedness payable by its terms more than one year from the date of incurrence thereof (or renewable or extendible at the option of the obligor for a period ending more than one year after such date of incurrence), capitalized rent, capital stock and surplus, surplus reserves and deferred income taxes and credits and other non-current liabilities, and (ii) all goodwill, trade names, trademarks, patents, unamortized debt discount, unamortized expense incurred in the issuance of debt, and other like intangibles (except prepaid royalties), which, in each case, under generally accepted accounting principles would be included on a consolidated balance sheet of the Company and its Restricted Subsidiaries, less (b) loans, advances, equity investments and contingent liabilities of every nature (other than accounts receivable arising from the sale of merchandise in the ordinary course of business) at the time outstanding which were made or incurred by the Company and its Restricted Subsidiaries to, in or for Unrestricted Subsidiaries or to, in or for corporations while they were Unrestricted Subsidiaries and which at the time of computation are not Subsidiaries. Principal Facility. Any manufacturing plant, warehouse, office building or parcel of real property (including fixtures but excluding leases and other contract rights which might otherwise be deemed real property) owned by the Company or any Restricted Subsidiary, provided each such plant, warehouse, office building or parcel of real property has a gross book value (without deduction for any depreciation reserves) of in excess of two percent of the Consolidated Net Tangible Assets of the Company and the Restricted Subsidiaries, other than any such plant, warehouse, office building or parcel of real property or portion thereof which, in the opinion of the Board of Directors of the Company, is not of material importance to the business conducted by the Company and its Subsidiaries taken as a whole. Restricted Subsidiary. Any corporation in which the Company directly or indirectly owns voting securities entitling it to elect a majority of the directors and (a) which (i) existed as such on the date of the Indenture or is the successor, directly or indirectly, to, or owns, directly or indirectly, any equity interest in, a corporation which so existed, (ii) has its principal place of business and the principal location of its assets in the United States (including its territories and possessions) or Canada or both, (iii) has as its principal business a business other than the financing of the acquisition or disposition of real, personal or intangible property or the owning, leasing, dealing in or developing of real property for residential or office building purposes, and (iv) does not have assets substantially all of which consist of the securities of one or more corporations which are not Restricted Subsidiaries, or (b) which, pursuant to the terms of the Indenture, is designated a Restricted Subsidiary by the Company after the date of the Indenture; provided, however, the Company may not designate a Subsidiary to be a Restricted Subsidiary if the Company would thereby breach any covenant or agreement contained in the Indenture (on the assumption that any transaction to which such Subsidiary was a party at the time of such designation and which would have given rise to Secured Debt or constituted a Sale and Leaseback Transaction at the time it was entered into had such Subsidiary then been a Restricted Subsidiary was entered into at the time of such designation). None of the existing principal operating subsidiaries of the Company are Restricted Subsidiaries under the Indenture. Sale and Leaseback Transaction. Any sale or transfer made by the Company or one or more Restricted Subsidiaries (except a sale or transfer made to the Company or one or more Restricted Subsidiaries) of any Principal Facility which (in the case of a Principal Facility which is a manufacturing plant, warehouse, office building or developed mining property) has been in operation, use or commercial production (exclusive of test and start-up periods) by the Company or any Restricted Subsidiary for more than 120 days prior to such sale or transfer, or which (in the case of a Principal Facility which is a parcel of real property other than a manufacturing plant, warehouse, office building or developed mining property) has been owned by the Company or any Restricted Subsidiary for more than 120 days prior to such sale or transfer, if such sale or transfer is made with the intention of leasing, or as part of an arrangement involving the lease, of such Principal Facility to the Company or a Restricted Subsidiary (except a lease for a period not exceeding 36 months, made with the intention that the use of the leased Principal Facility by the Company or such Restricted Subsidiary will be discontinued on or before the expiration of such period). Any Secured Debt otherwise permitted pursuant to the Indenture will not be deemed to create or be defined to be a Sale and Leaseback Transaction. Secured Debt. Any indebtedness for money borrowed by, or evidenced by a note or other similar instrument of, the Company or a Restricted Subsidiary, and any other indebtedness of the Company or a Restricted Subsidiary on which by the terms of such indebtedness interest is paid or payable, including obligations evidenced or secured by leases, installment sales agreements or other instruments in connection with industrial development bonds as defined in Section 103(c)(2) of the Internal Revenue Code of 1954 (other than indebtedness owed by a Restricted Subsidiary to the Company, by a Restricted Subsidiary to another Restricted Subsidiary or by the Company to a Restricted Subsidiary), which in any such case is secured by (a) a Security Interest in any Principal Facility, or (b) a Security Interest in any shares of stock owned directly or indirectly by the Company in a Restricted Subsidiary or in indebtedness for money borrowed by a Restricted Subsidiary from the Company or another Restricted Subsidiary. The securing in the foregoing manner of any previously unsecured debt shall be deemed to be the creation of Secured Debt at the time such security is given. The amount of Secured Debt at any time outstanding shall be the maximum aggregate amount then owing thereon by the Company and its Restricted Subsidiaries. Security Interest. Any mortgage, pledge, lien, encumbrance or other security interest which secures payment or performance of an obligation. Senior Funded Debt.

CERTAIN COVENANTS OF THE COMPANY Restriction on Creation of Secured Debt. The Indenture provides that so long as the Securities of any series are outstanding, the Company will not, and will not cause or permit a Restricted Subsidiary to, create, incur, assume or guarantee any Secured Debt or create any Security Interest securing any indebtedness existing on the date of the Indenture which would constitute Secured Debt if it were secured by a Security Interest in a Principal Facility unless the Securities will be secured equally and ratably (subject to applicable priorities of payment) by the Security Interest securing such Secured Debt or indebtedness, except that the Company and its Restricted Subsidiaries may incur certain Secured Debt without so securing the Securities. Among such permitted Secured Debt is indebtedness secured by (i) certain Security Interests to secure payment of the cost of acquisition, construction, development or improvement of property, (ii) Security Interests on property at the time of acquisition assumed by the Company or a Restricted Subsidiary, or on the property or on the outstanding shares or indebtedness of a corporation or firm at the time it becomes a Restricted Subsidiary or is merged into or consolidated with the Company or a Restricted Subsidiary or the Company or a Restricted Subsidiary acquires the properties of such corporation or firm as an entirety or substantially as an entirety, (iii) Security Interests arising from conditional sales agreements or title retention agreements with respect to property acquired by the Company or any Restricted Subsidiary, (iv) certain Security Interests to secure progress or advance payments, (v) Security Interests securing indebtedness of a Restricted Subsidiary owing to the Company or to another Restricted Subsidiary, (vi) mechanics' and other statutory liens arising in the ordinary course of business (including construction of facilities) in respect of obligations which are not due or which are being contested in good faith, (vii) liens for taxes, assessments or governmental charges not yet due or for taxes, assessments or governmental charges which are being contested in good faith, (viii) Security Interests (including judgment liens) arising in connection with legal proceedings so long as such proceedings are being contested in good faith and, in case of judgment liens, execution thereon is stayed, (ix) certain landlords' liens on fixtures, (x) Security Interests to secure partial, progress, advance or other payments or indebtedness incurred for the purpose of financing construction on or improvement of property subject to such Security Interests and (xi) certain Security Interests in favor, or made at the request, of governmental bodies. Additionally, such permitted Secured Debt includes (with certain limitations) any extension, renewal or refunding, in whole or in part, of any Secured Debt permitted at the time of the original incurrence thereof. In addition to the foregoing, the Company and its Restricted Subsidiaries may have Secured Debt, without equally and ratably securing the Securities, if the sum of (a) the amount of Secured Debt entered into after the date of the Indenture and otherwise prohibited by the Indenture plus (b) the aggregate value of Sale and Leaseback Transactions entered into after the date of the Indenture and otherwise prohibited by the Indenture does not exceed ten percent of Consolidated Net Tangible Assets. (Section 5.05) Restriction on Sale and Leaseback Transactions. The Indenture provides that so long as the Securities of any series are outstanding, the Company will not, and will not permit any Restricted Subsidiary to, enter into any Sale and Leaseback Transaction unless (a) the Company or such Restricted Subsidiary would be entitled to incur Secured Debt permitted by the Indenture only by reason of the provision described in the last sentence of the preceding paragraph equal in amount to the net proceeds of the property sold or transferred or to be sold or transferred pursuant to such Sale and Leaseback Transaction and secured by a Security Interest on the property to be leased without equally and ratably securing the Securities, or (b) the Company or a Restricted Subsidiary shall apply within one year after the effective date of such Sale and Leaseback Transaction, or shall have committed within one year after the effective date of such Sale and Leaseback Transaction to apply, an amount equal to such net proceeds (x) to the acquisition, construction, development or improvement of properties, facilities, or equipment used for operating purposes which are, or upon such acquisition, construction, development, or improvement will be, a Principal Facility or Facilities or a part thereof or (y) to the redemption of Securities or (z) to the repayment of Senior Funded Debt of the Company or of any Restricted Subsidiary (other than Senior Funded Debt owed to any Restricted Subsidiary), or in part to such acquisition, construction, development or improvement and in part to such redemption and/or repayment. In lieu of applying an amount equal to such net proceeds to such redemption the Company may, within one year after such sale or transfer, deliver to the Trustee Securities (other than Securities made the basis of a reduction in a mandatory sinking fund payment) for cancellation and thereby reduce the amount to be applied to the redemption of Securities by an amount equivalent to the aggregate principal amount of the Securities so delivered. (Section 5.06) Restrictions on Transfer of Principal Facility to Certain Subsidiaries. The Indenture provides that, so long as the Securities of any series are outstanding, the Company will not, and will not cause or permit any Restricted Subsidiary to, transfer any Principal Facility to any Subsidiary which was not a Restricted Subsidiary at the time of such transfer unless it shall apply within one year of the effective date of such transaction, or shall have committed within one year of such effective date to apply, an amount equal to the fair value of such Principal Facility at the time of such transfer (i) to the acquisition, construction, development or improvement of properties, facilities or equipment which are, or upon such acquisition, construction, development or improvement will be, a Principal Facility or Facilities or a part thereof or (ii) to the redemption of Securities or (iii) to the repayment of Senior Funded Debt of the Company or any Restricted Subsidiary (other than Senior Funded Debt owed to any Restricted Subsidiary), or in part to such acquisition, construction, development or improvement and in part to such redemption and/or repayment. In lieu of applying all or any part of such amount to such redemption the Company may, within one year of such transfer, deliver to the Trustee Securities of any series (other than Securities made the basis of a reduction in a mandatory sinking fund payment) for cancellation and thereby reduce the amount to be applied to the redemption of Securities by an amount equivalent to the aggregate principal amount of the Securities so delivered. (Section 5.07) MERGER The Indenture provides that the Company may consolidate with, or sell or convey all or substantially all of its assets to, or merge into any other corporation, provided that in any such case, (i) the successor corporation shall be a corporation organized and existing under the laws of the United States of America or a State thereof and such corporation shall expressly assume the due and punctual payment of the principal of (and premium, if any) and interest on all the Securities, according to their tenor, and the due and punctual performance and observance of all the covenants and conditions of the Indenture to be performed by the Company by supplemental indenture satisfactory to the Trustee, executed and delivered to the Trustee by such corporation; and (ii) immediately after giving effect to such transaction, no default shall have occurred and be continuing. Notwithstanding the foregoing, if, upon any such consolidation or merger of the Company with or into any other corporation, or upon any sale or conveyance of the property of the Company as an entirety or substantially as an entirety to any other corporation, or upon any acquisition by the Company by purchase or otherwise of all or any part of the properties of another corporation, any Principal Facility would thereupon become subject to any Security Interest securing indebtedness not permitted by the Indenture to be Secured Debt, the Company, prior to such consolidation, merger, sale, conveyance or acquisition, will secure the Securities outstanding, equally and ratably (subject to applicable priorities of payment) with the debt secured by such Security Interest. (Article Twelve) MODIFICATION OF THE INDENTURE With the consent of the Holders of more than 50% in aggregate principal amount of any series of Securities then outstanding, waivers, modifications and alterations of the terms of the Indenture may be made which affect the rights of the Holders of such series of Securities, except that no such modification or alteration may be made which will (a) extend the time of payment of the principal at maturity of, or the interest on, any such series of Securities, or reduce principal or premium or the rate of interest, without the consent of the Holder thereof, or (b) without the consent of all of the Holders of any series of Securities then outstanding, reduce the percentage of Securities of any such series, the Holders of which are required to consent (i) to any such supplemental Indenture, (ii) to rescind and annul a declaration that the Securities of any series are due and payable as a result of the occurrence of an Event of Default, (iii) to waive any past default under the Indenture and its consequences and (iv) to waive compliance with certain other provisions contained in the Indenture. (Sections 5.09 and 11.02) In addition, as indicated under "Events of Default" below, Holders of a majority in aggregate principal amount of the Securities of any series then outstanding may waive past defaults in certain circumstances and may direct the Trustee in enforcement of remedies. The Company and the Trustee may, without the consent of any Holders, modify and supplement the Indenture (i) to evidence the succession of another corporation to the Company under the Indenture; (ii) to evidence and provide for the replacement of the Trustee; (iii) with the Company's concurrence, to add to the covenants of the Company for the benefit of the Holders; (iv) to modify the Indenture to permit the qualification of any supplemental indenture under the Trust Indenture Act of 1939 (the "Trust Indenture Act"); and for certain other purposes. (Section 11.01) DEFEASANCE, SATISFACTION AND DISCHARGE PRIOR TO MATURITY OR REDEMPTION Defeasance of any Series. If the Company shall deposit with the Trustee, in trust, at or before maturity or redemption, lawful money or direct obligations of the United States of America or obligations the principal of and interest on which are guaranteed by the United States of America in such amounts and maturing at such times that the proceeds of such obligations to be received upon the respective maturities and interest payment dates of such obligations will provide funds sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay when due the principal (and premium, if any) and interest to maturity or to the redemption date, as the case may be, with respect to any series of Outstanding Securities, then the Company may cease to comply with the terms of the Indenture, including the restrictive covenants described above and the Events of Default described in clauses (d) and (e) under "Events of Default" below, except for (1) the Company's obligation to duly and punctually pay the principal of (and premium, if any) and interest on such series of Securities if the Securities are not paid from the money or securities held by the Trustee, (2) the Events of Default described in clauses (a), (b), (c), (f) and (g) under "Events of Default" below, and (3) certain other provisions of the Indenture including, among others, those relating to registration, transfer and exchange, lost or stolen securities, maintenance of place of payment and, to the extent applicable to such series, the redemption and sinking fund provisions of the Indenture. Defeasance of Securities of any series is subject to the satisfaction of certain specified conditions, including, among others, (i) the absence of an Event of Default at the date of the deposit, (ii) the perfection of the Holders' security interest in such deposit, and (iii) the absence of any conflicting interest of the Trustee under the Trust Indenture Act. (Section 13.02) Satisfaction and Discharge of any Series. Upon the deposit of money or securities contemplated above and the satisfaction of certain conditions, the Company may also cease to comply with its obligation duly and punctually to pay the principal of (and premium, if any) and interest on a particular series of Securities, or with any Events of Default with respect thereto, and thereafter the Holders of such series of Securities shall be entitled only to payment out of the money or securities deposited with the Trustee. Such conditions include, among others, except in certain limited circumstances involving a deposit made within one year of maturity or redemption, (i) the absence of an Event of Default at the date of deposit or on the 91st day thereafter, (ii) the delivery to the Trustee by the Company of an opinion of nationally recognized tax counsel, or receipt by the Company from, or publication of a ruling by the United States Internal Revenue Service, to the effect that Holders of the Securities of such series will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and discharge and will be subject to Federal income tax on the same amounts and in the same manner and at the same times as would have been the case if such deposit and discharge had not occurred, and (iii) that such satisfaction and discharge will not result in the delisting of the Securities of that series from any nationally recognized exchange on which they are listed. (Section 13.01) Federal Income Tax Consequences. Under current Federal income tax law, the deposit and defeasance described above under "Defeasance of any Series" will not result in a taxable event to any Holder of Securities or otherwise affect the Federal income tax consequences of an investment in the Securities of any series. A deposit and discharge described above under "Satisfaction and Discharge of any Series" may be treated as a taxable exchange of such Securities for beneficial interests in the trust consisting of the deposited money or securities. In that event, a Holder of Securities may be required to recognize gain or loss equal to the difference between the Holder's adjusted basis for the Securities and the amount realized by such Holder with respect to such exchange (which generally will be the fair market value of the beneficial interest in such trust). Thereafter, such Holder may be required to include in income a share of the income, gain and loss of the trust. As described above, it is generally a condition to such a deposit and discharge to obtain an opinion of tax counsel, or receipt by the Company from, or publication of a ruling by the United States Internal Revenue Service, to the effect that such deposit and discharge will not alter the Holders' tax consequences that would have been applicable in the absence of the deposit and discharge. Purchasers of the Securities should consult their own advisors with respect to the tax consequences to them of such deposit and discharge, including the applicability and effect of tax laws other than Federal income tax law. EVENTS OF DEFAULT As to any series of Securities, an Event of Default is defined in the Indenture as being: (a) default for 30 days in payment of any interest on the Securities of such series; (b) failure to pay principal or premium with respect to the Securities of such series, if any, when due; (c) failure in the deposit of any sinking fund installment with respect to any series of Securities when due; (d) failure to observe or perform any other covenant in the Indenture or Securities of any series (other than a covenant or warranty, a default in whose performance or whose breach is specifically dealt with in the section of the Indenture governing Events of Default), if such failure continues for 60 days after written notice by the Trustee or the Holders of at least 25% in aggregate principal amount of the Outstanding Securities of such series; (e) uncured or unwaived failure to pay principal of or interest on any other obligation for borrowed money of the Company (including default under any other series of Securities and including default by the Company on any guaranty of an obligation for borrowed money of a Restricted Subsidiary) beyond any period of grace with respect thereto if (i) the aggregate principal amount of any such obligation is in excess of $10,000,000 and (ii) the default in such payment is not being contested by the Company in good faith and by appropriate proceedings; (f) certain events of bankruptcy, insolvency, receivership or reorganization; or (g) any other Event of Default provided with respect to Securities of that series. (Section 7.01) The Trustee or the Holders of 25% in aggregate principal amount of the outstanding Securities of any series may declare the Securities of such series immediately due and payable upon the occurrence of any Event of Default (after expiration of any applicable grace period); in certain cases, the Holders of a majority in principal amount of the Outstanding Securities of any series may waive any past default and its consequences, except a default in the payment of principal, premium, if any, or interest (including sinking fund payments). (Sections 7.01 and 7.07) The Indenture provides that the Trustee shall, within 90 days after the occurrence of a default with respect to any such series for which there are Securities outstanding which is continuing, give to the Holders of such Securities notice of all uncured defaults known to it (the term default to include the events specified above without grace periods); provided that, except in the case of default in the payment of principal (or premium, if any) or interest on any of the Securities of any series or the payment of any sinking fund installment on the Securities of any series, the Trustee shall be protected in withholding such notice if it in good faith determines that the withholding of notice is in the interest of the Securityholders. (Section 7.08) Subject to the provisions of the Indenture relating to the duties of the Trustee in case an Event of Default with respect to any series of such Securities shall occur and be continuing, the Indenture provides that the Trustee shall be under no obligation to exercise any of its rights or powers under the Indenture at the request, order or direction of any of the Holders of Securities outstanding of any series unless such Holders shall have offered to the Trustee reasonable indemnity. (Sections 8.01 and 8.02) The right of a Holder to institute a proceeding with respect to the Indenture is subject to certain conditions precedent including notice and indemnity to the Trustee, but the Holder has a right to receipt of principal, premium, if any, and interest (subject to certain limitations with respect to defaulted interest) on their due dates or to institute suit for the enforcement thereof. (Section 7.04) So long as the Securities of any series remain outstanding the Company will be required to furnish annually to the Trustee an Officers' Certificate stating whether, to the best of the knowledge of the signers, the Company is in default under any of the provisions of the Indenture, and specifying all such defaults, and the nature thereof, of which they have knowledge. (Section 5.08) The Company will also be required to furnish to the Trustee copies of certain reports filed by the Company with the Commission. (Section 6.03) The Holders of a majority in principal amount of the Securities outstanding of such series will have the right to direct the time, method and place for conducting any proceeding for any remedy available to the Trustee, or exercising any power or trust conferred on the Trustee, provided that such direction shall be in accordance with law and the provisions of the Indenture. (Section 7.07) The Trustee will be under no obligation to act in accordance with such direction unless such Holders shall have offered the Trustee reasonable security or indemnity against costs, expenses and liabilities which may be incurred thereby. (Section 8.02) INFORMATION CONCERNING THE TRUSTEE First Trust of New York, National Association, Trustee under the Indenture, is also the trustee for the Company's 9.875% Sinking Fund Debentures due March 15, 2011, the Company's 6% Notes due October 15, 2003 and the Company's 7% Debentures due December 15, 2013, all of which have been issued under the Indenture and are unsecured obligations of the Company ranking equally with the Debt Securities. PLAN OF DISTRIBUTION The Company may sell Debt Securities to or through underwriters or dealers, directly to one or more purchasers, through agents or through a combination of the foregoing. Unless otherwise set forth in the Prospectus Supplement, such underwriters will include either or both of Goldman, Sachs & Co. and J.P. Morgan Securities Inc., acting alone or as representatives of a group of underwriters. Either or both of Goldman, Sachs & Co. and J.P. Morgan Securities Inc. may also act as agents. The distribution of the Debt Securities may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices. In connection with the sale of Debt Securities, underwriters may receive compensation from the Company or from purchasers of Debt Securities for whom they may act as agents in the form of discounts, concessions or commissions. Underwriters may sell Debt Securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. Underwriters, dealers and agents that participate in the distribution of Debt Securities may be deemed to be underwriters, and any discounts or commissions received by them from the Company and any profit on the resale of Debt Securities by them may be deemed to be underwriting discounts and commissions, under the Securities Act. Any such underwriter or agent will be identified, and any such compensation received from the Company will be described in the Prospectus Supplement. Under agreements which may be entered into by the Company, underwriters and agents who participate in the distribution of Debt Securities may be entitled to indemnification by the Company against certain liabilities, including liabilities under the Securities Act. If so indicated in the Prospectus Supplement, the Company will authorize underwriters or other persons acting as the Company's agents to solicit offers by certain institutions to purchase Offered Securities from the Company pursuant to contracts providing for payment and delivery on a future date. Institutions with which such contracts may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and others, but in all cases such institutions must be approved by the Company. The obligations of any purchaser under any such contract will be subject to the condition that the purchase of the Offered Securities shall not at the time of delivery be prohibited under the laws of any jurisdiction to which such purchaser is subject. The underwriters and such other agents will not have any responsibility in respect of the validity or performance of such contracts. Unless otherwise indicated in the Prospectus Supplement, the Company does not intend to list any of the Debt Securities on a national securities exchange. In the event the Debt Securities are not listed on a national securities exchange, certain broker-dealers may make a market in the Debt Securities, but will not be obligated to do so and may discontinue any market making at any time without notice. No assurance can be given that any broker-dealer will make a market in the Debt Securities or as to the liquidity of the trading market for the Debt Securities, whether or not the Debt Securities are listed on a national securities exchange. The Prospectus Supplement with respect to any Offered Securities will state, if known, whether or not any broker-dealer intends to make a market in such Offered Securities. If no such determination has been made, the Prospectus Supplement will so state. LEGAL MATTERS The legality of the Debt Securities will be passed upon by White & Case, 1155 Avenue of the Americas, New York, New York 10036, as counsel for the Company, and by Mayer, Brown & Platt, 190 South LaSalle Street, Chicago, Illinois 60603, as counsel for any underwriters or agents.

INDEMNIFICATION OF DIRECTORS AND OFFICERS. The Company's By-Laws provide for indemnification, to the fullest extent permitted by applicable law, of any of its directors and officers who are, or have been, or are threatened to be, made a party to an action or proceeding, whether civil or criminal, by reason of the fact that such director or officer is a director or officer of the Company, against any judgments, fines, amounts paid in settlement and expenses, including attorneys' fees, or any appeal therein. The By-Laws also provide that additional indemnification may be provided by the Company to any other person to the extent permitted by applicable law. The Company's Certificate of Incorporation provides that a current or former director shall not be liable to the Company or its shareholders for damages for any breach of duty except to the extent New York State law prohibits elimination or limitation of such liability. The Company has insurance to indemnify its directors and officers, within the limits of the Company's insurance policies, for those liabilities in respect of which such indemnification insurance is permitted under the laws of the State of New York. Reference is made to Sections 721-726 of the New York Business Corporation Law ("B.C.L."), which are summarized below. Section 721 of the B.C.L. provides that indemnification pursuant to the B.C.L. shall not be deemed exclusive, provided that no indemnification may be made if a judgment or other final adjudication adverse to the director or officer establishes that (i) his acts were committed in bad faith or were the result of active and deliberate dishonesty, and, in either case, were material to the cause of action so adjudicated, or (ii) he personally gained in fact a financial profit or other advantage to which he was not legally entitled. Section 722 of the B.C.L. provides that a corporation may indemnify a director or officer made, or threatened to be made, a party to any action whether derivative or nonderivative, or whether civil or criminal, against judgments, fines, amounts paid in settlement and reasonable expenses actually and necessarily incurred as a result of such action, if such director or officer acted in good faith, for a purpose which he reasonably believed to be in the best interests of the corporation and, in criminal actions or proceedings, in addition, had no reasonable cause to believe that his conduct was unlawful. In derivative actions, the statute provides that no indemnification shall be made in respect of (1) a threatened action, or a pending action which is settled or otherwise disposed of, or (2) any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and to the extent an appropriate court determines that the person is fairly and reasonably entitled to indemnification. Section 723 of the B.C.L. specifies the manner in which payment of such indemnification may be authorized by the corporation. It provides that indemnification by a corporation is mandatory in any case in which the director or officer has been successful, whether on the merits or otherwise, in defending an action. In any other case, indemnification under Section 722 of the B.C.L. or as otherwise permitted under Section 721 of the B.C.L. may be made by the corporation only if authorized by the appropriate corporate action as set forth in such Section 723. Section 724 of the B.C.L. provides that upon proper application by a director or officer, indemnification shall be awarded by a court to the extent authorized under Sections 722 and 723 of the B.C.L. Section 725 of the B.C.L. contains certain other miscellaneous provisions affecting the indemnification of directors and officers, including provision for the return of amounts paid as indemnification if any such person is ultimately found not to be entitled thereto. Section 726 of the B.C.L. authorizes the purchase and maintenance of insurance to indemnify (1) a corporation for any obligation which it incurs as a result of the indemnification of directors and officers under the above sections, (2) directors and officers in instances in which they may be indemnified by a corporation under such sections, and (3) directors and officers in instances in which they may not otherwise be indemnified by a corporation under such sections, provided the contract of insurance covering such directors and officers provides, in a manner acceptable to the New York State Superintendent of Insurance, for a retention amount and for co-insurance. Such insurance may not provide for the indemnification, other than defense costs, of any director or officer whose deliberate and active dishonesty is held material to an adjudicated cause of action in a judgment adverse to the insured nor of any director or officer who personally gained in fact a financial profit or other advantage to which he was not legally entitled.

UNDERTAKINGS. The undersigned registrant hereby undertakes: (1) to file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement; (iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; Provided, however, that paragraphs (1) (i) and (1) (ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. (2) that, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at the time shall be deemed to be the initial bona fide offering thereof. (3) to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Insofar as indemnification for the liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions described under Item 15 above, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in such Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in St. Louis, Missouri, on the 15th day of February, 1995.
