ABOUT THIS PROSPECTUS SUPPLEMENT

        This document is in two parts. The first part is this prospectus supplement, which describes the terms of the notes that we are currently offering. The second part is the accompanying prospectus, which gives more general information, some of which may not apply to the notes that we are currently offering. Generally, the term "prospectus" refers to both parts combined.

        You should read this prospectus supplement along with the accompanying prospectus. You should rely only on the information contained in or incorporated by reference in this prospectus supplement and the accompanying prospectus. We have not, and the underwriters have not, authorized any other person to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. You should not assume that the information provided by this prospectus supplement or the accompanying prospectus is accurate as of any date other than the date on the front of these documents. Our business, financial condition, results of operations and prospects may have changed since those dates. The notes are being offered and sold only in jurisdictions where offers and sales are permitted.

        If the information varies between this prospectus supplement and the accompanying prospectus, the information in this prospectus supplement supersedes the information in the accompanying prospectus.

        References to "McCormick," "we," "us" and "our" in this prospectus supplement and the accompanying prospectus are to McCormick & Company, Incorporated and its consolidated subsidiaries or, as the context may require, McCormick & Company, Incorporated only.


CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

        This prospectus supplement and the information incorporated by reference in it include "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act") and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). We intend the forward-looking statements to be covered by the safe harbor provisions for forward-looking statements in these sections.

        All statements regarding our expected financial position and operating results, our business strategy, our financing plans, our future capital requirements, forecasted demographic and economic trends relating to our industry, our ability to complete acquisitions, to realize anticipated cost savings and other benefits from acquisitions and to recover acquisition-related costs, and similar matters are forward-looking statements.

        These statements are subject to known and unknown risks, uncertainties and other factors that could cause our actual results to differ materially from the statements. The forward-looking information is based on various factors and was derived using numerous assumptions.

        In some cases, you can identify these statements by our use of forward-looking words such as "may," "will," "would," "should," "anticipate," "estimate," "expect," "plan," "believe," "predict," "project," "potential" or "intend." You should be aware that these statements only reflect our predictions. Actual events or results may differ substantially.

PROSPECTUS SUPPLEMENT SUMMARY

        This summary may not contain all the information that may be important to you. You should read the entire prospectus supplement and the accompanying prospectus and the documents incorporated and deemed to be incorporated by reference herein and therein, including the financial statements and related notes, before making an investment decision.

The Offering

Issuer   McCormick & Company, Incorporated

Securities Offered
 
$        million aggregate principal amount of        % Notes due 2015.

Maturity
 
The notes will mature on                         , 2015.

Interest Rate
 
The notes will bear interest at a rate of        % per year, payable semiannually in arrears on and of each year, commencing on                         , 2006.

Ranking
 
The notes will be unsecured senior obligations of ours and will rank equally with all of our other unsecured and unsubordinated indebtedness from time to time outstanding. The notes will be effectively subordinated to:

 
 
•
any of our secured indebtedness to the extent of the value of the assets securing that debt; and

 
 
•
all indebtedness for money borrowed and other liabilities of our subsidiaries.

 
 
As of August 31, 2005, after giving effect to this offering and the application of the net proceeds as described under "Use of Proceeds" in this prospectus supplement, we would have had approximately $682.0 million of unsecured debt (including the notes) outstanding, $2.8 million of which was debt of our subsidiaries, and we would have had $14.5 million of secured debt outstanding.

Covenants
 
The indenture governing the notes contains covenants that will limit our ability to:

 
 
•
create specified liens securing debt;

 
 
•
engage in specified sale-leaseback transactions; and

 
 
•
merge, consolidate or transfer our property and assets substantially as an entirety.

 
 
These covenants apply to McCormick and, in the case of the limitations on liens and sale-leaseback transactions, to certain of our corporate subsidiaries that own principal properties, as defined in the indenture. As of August 31, 2005, less than one percent of McCormick's consolidated total assets were held through partnerships and other non-corporate entities.
       

S-4


Optional Redemption
 
The notes will be redeemable at our option, at any time in whole or from time to time in part, at a redemption price equal to the greater of (1) 100% of the principal amount of the notes to be redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest thereon (exclusive 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 Treasury Rate plus basis points, plus in either case accrued and unpaid interest thereon to the date of redemption. See "Description of Notes—Optional Redemption."

Sinking Fund
 
None.

Use of Proceeds
 
We intend to use the net proceeds from this offering for general corporate purposes, including refinancing existing indebtedness, future acquisitions, capital expenditures and working capital.

Risk Factors
 
See "Risk Factors" beginning on page S-6 of this prospectus supplement for a discussion of the factors you should consider carefully before deciding to invest in the notes.

S-5


RISK FACTORS

        Investing in our notes involves various risks. You should carefully consider the risks and uncertainties described below and the other information in this prospectus supplement, the accompanying prospectus and in the documents incorporated by reference before deciding whether to purchase our notes.

Fluctuations In The Foreign Currency Markets May Negatively Impact Us.

        We are exposed to fluctuations in foreign currency cash flows primarily related to raw material purchases. We are also exposed to fluctuations in the value of foreign currency investments in subsidiaries and unconsolidated affiliates and cash flows related to repatriation of these investments. Additionally, we are exposed to volatility in the translation of foreign currency earnings to U.S. dollars. Primary exposures include the U.S. dollar versus the functional currencies of our major markets (Euro, British pound sterling, Canadian dollar, Australian dollar, Mexican peso, Chinese renminbi and Japanese yen). On occasion, we may enter into forward and option contracts to manage these foreign currency risks. However, these contracts may not effectively limit or eliminate our exposure to a decline in operating results due to foreign currency translation. Therefore, we cannot assure you that future exchange rate fluctuations will not have a negative impact on our business, financial position or operating results.

Increases In Interest Rates May Negatively Impact Us.

        We had total outstanding short-term borrowings of approximately $200 million at an average interest rate of approximately 3.7% on August 31, 2005. Our policy is to manage our interest costs using a mix of fixed and variable rate debt. We also use interest rate swaps to achieve a desired proportion of fixed and variable rate debt. We utilize derivative financial instruments to enhance our ability to manage risk, including foreign exchange and interest rate exposures that exist as part of our ongoing business operations. We do not enter into contracts for trading purposes, nor are we a party to any leveraged derivative instrument. Our use of derivative financial instruments is monitored through regular communication with senior management and the utilization of written guidelines. However, our use of these instruments may not effectively limit or eliminate our exposure to a decline in operating results due to changes in interest rates. Therefore, we cannot assure you that future interest rate increases will not have a negative impact on our business, financial position or operating results.

Price Fluctuations In The Commodity Markets May Negatively Impact Us.

        We purchase certain raw materials that are subject to price volatility caused by weather and other unpredictable factors. The most significant raw materials are vanilla, cheese, pepper, packaging supplies, garlic, onion and capsicums. While future movements of raw material costs are uncertain, a variety of programs, including strategic raw material purchases, purchases of raw material for future delivery and customer price adjustments, help us address this risk. Generally, we do not use derivatives to manage the volatility related to this risk. Even if we did use such instruments, however, their use might not effectively limit or eliminate our exposure to a decline in operating results due to changes in commodity prices. Therefore, we cannot assure you that future commodity price fluctuations will not have a negative impact on our business, financial position or operating results.

There May Not Be Any Trading Market For the Notes; Many Factors Affect The Trading And Market Value Of the Notes.

        Upon issuance, the notes will not have an established trading market. We cannot assure that a trading market for the notes will ever develop or be maintained if developed. In addition to our

S-6


creditworthiness, many factors affect the trading market for, and trading value of, the notes. These factors include:

        There may be a limited number of buyers when you decide to sell the notes. This may affect the price you receive for the notes or your ability to sell the notes at all. You should not purchase notes unless you understand and know you can bear all of the investment risks involving the notes.

Our Credit Ratings May Not Reflect All Risks Of An Investment In The Notes.

        Our credit ratings may not reflect the potential impact of all risks related to the market value of the notes. However, real or anticipated changes in our credit ratings will generally affect the market value of the notes.

S-7


RATIO OF EARNINGS TO FIXED CHARGES

        For the purpose of calculating the ratio of earnings to fixed charges, "earnings" consist of income from consolidated operations before income taxes, plus fixed charges (net of capitalized interest), amortization of capitalized interest and dividends from unconsolidated subsidiaries. "Fixed charges" consist of interest, whether expensed or capitalized (including amortization of debt discount), and that portion of rental expense that is representative of interest.

USE OF PROCEEDS

        Our net proceeds from this offering are estimated to be approximately $    million after deducting the underwriting discount and our estimated offering expenses. We intend to use the net proceeds from the sale of the notes for general corporate purposes, including refinancing existing indebtedness, future acquisitions, capital expenditures and working capital. Until we apply the net proceeds for specific purposes, we may reinvest such net proceeds in short-term or marketable securities.

S-8


DESCRIPTION OF NOTES

        The following description of the particular terms of the notes we are offering supplements and, to the extent inconsistent, supersedes the description of the general terms of the debt securities set forth under the section entitled "Description of Debt Securities" in the accompanying prospectus. You should read the accompanying prospectus in conjunction with this prospectus supplement. Because this is a summary, it does not contain all the information that may be important to you. You should also read the entire indenture, including the definitions of some terms, before you make any investment decision.

General

        The notes will be issued as a separate series of debt securities under the indenture dated as of December 5, 2000, between us and SunTrust Bank, as trustee, initially limited in aggregate principal amount to $200 million. The indenture does not limit the amount of debt securities that we may issue under the indenture, and we may, without the consent of the holders of the notes, reopen this series of notes and issue additional notes on the same terms and conditions and with the same CUSIP number as the notes being offered hereby.

        The notes will be unsecured senior obligations of ours and will rank equally with all of our other unsecured and unsubordinated indebtedness from time to time outstanding. The notes are not guaranteed by any of our subsidiaries. The notes will be effectively subordinated to all of our secured debt (to the extent of the value of the collateral pledged to secure that debt) and to all indebtedness and other liabilities of our subsidiaries. As of August 31, 2005, after giving effect to this offering and the application of the net proceeds as described under "Use of Proceeds" in this prospectus supplement, we would have had approximately $682.0 million of unsecured debt (including the notes) outstanding, $2.8 million of which was debt of our subsidiaries, and we would have had $14.5 million of secured debt outstanding. Except as described below under "—Certain Covenants", the indenture does not restrict the amount of secured or unsecured debt that we or our subsidiaries may incur.

        The notes will be issued only in fully registered form without coupons, in minimum denominations of $1,000 and integral multiples of $1,000. Notices or demands to or upon us with respect to the notes and the indenture may be served and, in the event that notes are issued in definitive certificated form, notes may be surrendered for payment, registration of transfer or exchange, at the office or agency maintained by us for this purpose in the Borough of Manhattan, The City of New York, currently the corporate trust office of the trustee, located at SunTrust Bank, c/o Depository Trust Company, 55 Water Street, New York, New York 10041.

Maturity and Interest

        The notes will mature on                        , 2015. The notes will not be subject to any sinking fund provision.

        The notes will bear interest at the rate of        % per year from                        , 2005, or from the most recent date to which interest has been paid or provided for, payable semiannually in arrears on        and        of each year, commencing on                        , 2006, to the persons in whose names the notes are registered at the close of business on the         or        , as the case may be, immediately prior to such interest payment dates, regardless of whether any such regular record date is a business day. Interest on the notes will be computed on the basis of a 360-day year consisting of twelve 30-day months.

        If any interest payment date, any redemption date, the maturity date or any other date on which the principal of or premium, if any, or interest on a note becomes due and payable falls on a day that is not a business day, the required payment shall be made on the next business day as if it were made

S-9


on the date the payment was due, and no interest shall accrue on the amount so payable for the period from and after the interest payment date, redemption date, maturity date or other date, as the case may be.

Optional Redemption

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

plus, in either case, accrued and unpaid interest thereon to the date of redemption.

        "Treasury Rate" means, with respect to any redemption date,

        "Comparable Treasury Issue" means the United States Treasury security selected by an Independent Investment Banker as having an actual or interpolated 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 a comparable maturity to the remaining term of such notes.

        "Independent Investment Banker" means Banc of America Securities LLC or Wachovia Capital Markets, LLC or either of their respective successors, or if both such firms are unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed 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" means (1) Banc of America Securities LLC or its affiliates which are primary U.S. Government securities dealers in The City of New York (a "Primary Treasury Dealer"),

S-10


and its successors, and (2) three other Primary Treasury Dealers selected by us; provided, however, that if any of the foregoing or their affiliates shall cease to be a Primary Treasury Dealer, we shall substitute therefor another Primary Treasury Dealer.

        "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 asked 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., New York time, on the third business day preceding such redemption date.

        Notice of any redemption will be mailed by first class mail at least 30 days but not more than 60 days before the redemption date to each holder of notes to be redeemed at its registered address.

        In the case of a partial redemption, selection of the notes for redemption will be made pro rata, by lot or by such other method as the trustee in its sole discretion deems appropriate and fair. No notes of a principal amount of $1,000 or less will be redeemed in part. If any note is to be redeemed in part only, the notice of redemption that relates to the note will state the portion of the principal amount of the note to be redeemed. A new note in a principal amount equal to the unredeemed portion of the note will be issued in the name of the holder of the note upon surrender for cancellation of the original note.

        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 thereof called for redemption.

        We will pay interest to a person other than the holder of record on the record date if we elect to redeem the notes on a date that is after a record date but on or prior to the corresponding interest payment date. In this instance, we will pay accrued interest on the notes being redeemed to, but not including, the redemption date to the same person to whom we will pay the principal of those notes.

Definitions

        "Attributable Debt" with respect to any sale leaseback transaction that is subject to the restrictions described under "Certain Covenants—Limitation On Sale and Leaseback" means the lesser of:

        "Consolidated Net Tangible Assets" means the total assets of McCormick and its consolidated subsidiaries, including the investment in (at equity) and the net amount of advances to and accounts receivable from corporations which are not consolidated subsidiaries less the following:

S-11

        "Funded Debt" means any indebtedness of McCormick or a Restricted Subsidiary for borrowed money having a maturity of more than 12 months from the date such indebtedness was incurred or having a maturity of less than 12 months but by its terms being renewable or extendable beyond 12 months from the date such indebtedness was incurred at the option of the obligor.

        "Principal Property" means any manufacturing or processing plant or warehouse, together with the land upon which it is erected and any fixtures and equipment comprising a part thereof, owned by us or any Restricted Subsidiary and located in the United States, the book value (net of depreciation) of which on the date as of which the determination is being made is an amount which exceeds 1% of Consolidated Net Tangible Assets, other than any such manufacturing or processing plant or warehouse or any portion thereof or any such fixture or equipment (together with the land upon which it is erected and any fixtures and equipment comprising a part thereof) (i) which is financed by Industrial Development Bonds or (ii) which, in the opinion of our board of directors, is not of material importance to the total business conducted by us and our Subsidiaries, taken as a whole.

        "Restricted Subsidiary" means any Subsidiary that owns, operates or leases one or more Principal Properties.

        "Subsidiary" means each corporation of which we, or we and one or more Subsidiaries, or any one or more Subsidiaries, directly or indirectly own securities entitling the holders thereof to elect a majority of the directors, either at all times or so long as there is no default or contingency that permits the holders of any other class or classes of securities to vote for the election of one or more directors.

Certain Covenants

        The following covenants apply to us and to certain of our corporate subsidiaries that own principal properties, as defined in the indenture. As of August 31, 2005, less then one percent of our consolidated total assets were held through partnerships and other non-corporate entities.

Limitations on Liens

        We will not, and will not permit any Restricted Subsidiary to create, assume or suffer to exist any mortgage, security interest, pledge or lien ("Lien") of or upon any Principal Property, or any shares of capital stock or evidences of indebtedness for borrowed money issued by any Restricted Subsidiary and owned by us or any Restricted Subsidiary, whether owned at the date of the Indenture or acquired after, without providing that the notes shall be secured by such Lien equally and ratably with any and all other indebtedness or obligations thereby secured, so long as such indebtedness or obligations shall be so secured.

S-12


        This restriction does not apply to:

Limitations on Sale and Leaseback

        Except as described below under "—Exempted Indebtedness," we will not, nor will we permit any Restricted Subsidiary to, enter into any arrangement with any Person providing for the leasing (as lessee) by us or any Restricted Subsidiary of any Principal Property (except for temporary leases for a term, including any renewal, of not more than three years and except for leases between us and a Restricted Subsidiary or between Restricted Subsidiaries) which property has been or is to be sold or transferred by us or a Restricted Subsidiary to such Person unless either:

S-13

Exempted Indebtedness

        Notwithstanding the limitations on Liens and sale and leaseback transactions outlined above, we or any Restricted Subsidiary may create, assume or suffer to exist Liens or enter into sale and leaseback transactions not otherwise permitted as described above provided that at the time of such event, and after giving effect thereto, the sum of outstanding indebtedness for borrowed money incurred after the date of the Indenture and secured by Liens not otherwise permitted as set forth above plus the Attributable Debt in respect of such sale and leaseback transactions entered into after the date of the Indenture not otherwise permitted as set forth above does not exceed 15% of Consolidated Net Tangible Assets properly appearing on a consolidated balance sheet of McCormick.

        In addition, subject to the limitations set forth above, we may, in the future, enter into certain transactions such as the sale of our properties and assets substantially as an entirety or a merger or consolidation with another entity that could increase the amount of our indebtedness or otherwise adversely affect our financial condition or results of operations, which may have an adverse effect on our ability to service our indebtedness, including the notes. We have no present intention of engaging in a highly leveraged or similar transaction involving us.

Events of Default

        The notes are subject to the events of default described under the section entitled "Description of Debt Securities—Events of Default" in the accompanying prospectus.

S-14

Covenant Defeasance

Modification and Waiver

        The notes are subject to provisions allowing, under some conditions, the modification or amendment of the indenture or waiver of our compliance with some provisions of the indenture, as described under the section entitled "Description of Debt Securities—Modification and Waiver" in the accompanying prospectus.

S-15


Book-Entry System

        The Depository Trust Company, New York, NY, or DTC, will act as securities depository for the notes. The notes will be represented by one or more registered global securities (referred to as the registered global security) registered in the name of Cede & Co. (the nominee of DTC), or such other name as may be requested by an authorized representative of DTC. Accordingly, beneficial interests in the notes will be shown on, and transfers of the notes will be effected only through, records maintained by DTC and its participants. Except in the limited circumstances described in the indenture, owners of beneficial interests in the registered global security representing the notes will not be entitled to receive notes in definitive form and will not be considered holders of notes under the indenture.

        DTC has advised us and the underwriters as follows: The Depository Trust Company is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code and a "clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities that its participants (referred to as direct participants) deposit with DTC. DTC also facilitates the settlement among direct participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in direct participants' accounts, thereby eliminating the need for physical movement of securities certificates. Direct participants include securities brokers and dealers (including certain of the underwriters), banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation ("DTCC"). DTCC, in turn, is owned by a number of direct participants of DTC and Members of the National Securities Clearing Corporation, Fixed Income Clearing Corporation and Emerging Markets Clearing Corporation (NSCC, FICC and EMCC, also subsidiaries of DTCC), as well as by the New York Stock Exchange, Inc., the American Stock Exchange LLC and the National Association of Securities Dealers, Inc. Access to DTC's book-entry system is also available to others, such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly (referred to as indirect participants). The rules applicable to DTC and its direct and indirect participants are on file with the SEC.

        Purchases of notes under DTC's system must be made by or through direct participants, which will receive a credit for such notes on DTC's records. The ownership interest of each actual purchaser of notes represented by the registered global security (referred to as the beneficial owner) is in turn to be recorded on the direct and indirect participants' records. Beneficial owners will not receive written confirmation from DTC of their purchase, but beneficial owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct or indirect participants through which such beneficial owners entered into the transaction. Transfers of ownership interests in the registered global security representing notes are to be accomplished by entries made on the books of direct and indirect participants acting on behalf of beneficial owners. Beneficial owners will not receive notes in definitive form, except in the event that use of the book-entry system for such notes is discontinued or upon the occurrence of certain other events described in the accompanying prospectus and in this prospectus supplement.

        To facilitate subsequent transfers, the registered global security representing notes that are deposited by direct participants is registered in the name of DTC's partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of the registered global security with DTC and its registration in the name of Cede & Co. or such other nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the registered global security representing the notes; DTC's records reflect only the identity of the direct participants to whose accounts such notes are credited, which may or may not

S-16


be the beneficial owners. The direct or indirect participants will remain responsible for keeping account of their holdings on behalf of their customers.

        Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants, and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

        Neither DTC nor Cede & Co. (or any other DTC nominee) will consent or vote with respect to the registered global security representing the notes unless authorized by a direct participant in accordance with DTC's procedures. Under its usual procedures, DTC mails an omnibus proxy (referred to as an omnibus proxy) to us as soon as possible after the applicable record date. The omnibus proxy assigns Cede & Co.'s consenting or voting rights to those direct participants to whose accounts the notes are credited on the applicable record date (identified in a listing attached to the omnibus proxy).

        Principal, premium, if any, and interest payments on the registered global security representing the notes will be made to Cede & Co., or such nominee as may be requested by an authorized representative of DTC. DTC's practice is to credit direct participants' accounts upon DTC's receipt of funds and corresponding detail information from us or the trustee on the payment date in accordance with their respective holdings shown on DTC's records. Payments by direct and indirect participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in "street name," and will be the responsibility of those direct and indirect participants and not of DTC, the trustee or McCormick, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of principal, premium, if any, and interest to Cede & Co. (or such other nominee) is the responsibility of McCormick or the trustee, disbursement of those payments to direct participants is the responsibility of DTC, and disbursement of those payments to the beneficial owners is the responsibility of the direct and indirect participants. Neither we nor the trustee will have any responsibility or liability for the disbursements of payments in respect of ownership interests in the notes by DTC or the direct or indirect participants or for maintaining or reviewing any records of DTC or the direct or indirect participants relating to ownership interests in the notes or the disbursement of payments in respect of the notes.

        DTC may discontinue providing its services as securities depository with respect to the notes at any time by giving reasonable notice to us or the trustee. Under such circumstances, and in the event that a successor securities depository is not obtained, notes in definitive form are required to be printed and delivered to each holder.

        We may decide to discontinue use of the system of book-entry transfers through DTC (or a successor securities depository). In that event, notes in definitive form will be printed and delivered.

        The information in this section concerning DTC and DTC's book-entry system has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy of this information.

Same-Day Funds Settlement System and Payment

        We will make all payments of principal and interest in immediately available funds.

        Secondary trading in long-term notes of corporate issuers is generally settled in clearinghouse or next-day funds. In contrast, the notes will trade in DTC's Same-Day Funds Settlement System until maturity, and secondary market trading activity in the notes will therefore be required by DTC to settle in immediately available funds. No assurance can be given as to the effect, if any, of settlement in immediately available funds on trading activity in the notes.

CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES

        The following summary describes certain material U.S. federal income tax consequences of the acquisition, ownership and disposition of the notes by beneficial owners of the notes. This summary is based on the Internal Revenue Code of 1986, as amended (the "Code"), and Treasury regulations, rulings and judicial decisions as of the date hereof, all of which are subject to change, possibly on a retroactive basis. The discussion applies only to beneficial owners who acquire the notes in this offering at the initial offering price and who will hold the notes as capital assets within the meaning of Section 1221 of the Code. This summary does not address all aspects of U.S. federal income taxation that may be relevant to holders of the notes in light of their particular circumstances or to holders subject to special rules (such as broker-dealers, banks or other financial institutions, insurance companies, partnerships, tax-exempt organizations, persons that have a functional currency other than the U.S. dollar, certain U.S. expatriates and persons who hold the notes as part of a straddle, hedging or conversion transaction). This summary does not address the effects of any state, local or non-U.S. tax laws. Prospective holders should consult their tax advisors as to the particular tax consequences to them of acquiring, holding or disposing of the notes.

        For purposes of the following discussion, a "U.S. holder" is a beneficial owner of a note that is for U.S. federal income tax purposes:

        For purposes of the following discussion, a "non-U.S. holder" means a beneficial owner of a note (other than a partnership or other entity treated as a partnership for U.S. federal income tax purposes) that is not a U.S. holder.

        If a partnership (including for this purpose any entity treated as a partnership for U.S. federal income tax purposes) is a beneficial owner of a note, the treatment of a partner in the partnership generally will depend on the status of the partner and the activities of the partnership. Partnerships and partners in such partnerships should consult their tax advisors about the U.S. federal income tax consequences of owning and disposing of a note.

U.S. Holders

        Payments of Interest.    Interest paid with respect to the notes will generally be taxable to a U.S. holder as ordinary income at the time accrued or received, in accordance with such U.S. holder's regular method of accounting for U.S. federal income tax purposes.

        Disposition of Notes.    Upon the sale, exchange, redemption, retirement or other disposition of a note, a U.S. holder generally will recognize taxable gain or loss equal to the difference between the amount realized on the sale, exchange, redemption, retirement or other disposition (except to the extent of accrued but unpaid interest not previously included in income, which will be taxable as ordinary income) and such holder's adjusted tax basis in the note. A holder's adjusted tax basis in a note is generally equal to the cost of the note to such holder, reduced by any payments of principal on the note. Any such gain or loss will be capital gain or loss, and will be long-term capital gain or loss if

S-18


a U.S. holder has held the note for more than one year. Certain U.S. holders (including individuals) are eligible for a preferred rate of tax in respect to long term capital gain. The deductibility of capital losses by U.S. holders is subject to limitations.

        Satisfaction and Discharge.    If we were to obtain a discharge of the Indenture within one year of maturity or redemption date with respect to all of the notes then outstanding, as described in this prospectus supplement under "Description of Notes—Satisfaction and Discharge," such discharge would generally be deemed to constitute a taxable exchange of the notes outstanding for other property. In such case, a U.S. holder would be required to recognize capital gain or loss in connection with such deemed exchange. In addition, after such deemed exchange, a U.S. holder might also be required to recognize income from the property deemed to have been received in such exchange over the remaining life of the transaction in a manner or amount that is different than if the discharge had not occurred. U.S. holders should consult their tax advisors as to the specific consequences arising from a discharge in their particular situations.

Non-U.S. Holders

        Payments of Interest.    In general, U.S. federal income or withholding tax will not apply to any payment of interest on a note to a non-U.S. holder if the interest is not effectively connected with the non-U.S. holder's conduct if a trade or business within the U.S. and such interest qualifies for the "portfolio interest exemption." The portfolio interest exemption generally will be met if the holder:

        Special certification and other rules apply to certain non-U.S. holders that are pass-through entities rather than individuals or corporations, particularly entities treated as partnerships for U.S. federal income tax purposes, and to non-U.S. holders acting as (or holding notes through) intermediaries.

        If a non-U.S. holder cannot satisfy the requirements described above, payments of interest will be subject to the 30% U.S. federal withholding tax, unless the holder provides us with a properly executed (i) IRS Form W-8BEN, or successor form, claiming an exemption from or reduction in withholding under the benefit of a tax treaty or (ii) IRS Form W-8ECI, or successor form, stating that interest paid on the note is not subject to withholding tax because it is effectively connected with the non-U.S. holder's conduct of a trade or business in the U.S.

        If a non-U.S. holder is engaged in a trade or business in the U.S. and interest on a note is effectively connected with the conduct of that trade or business and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment or fixed base, then such holder (although exempt from the 30% withholding tax) will generally be subject to U.S. federal income tax on that interest on a net income basis in the same manner as if the holder were a U.S. person as defined under the Code. In addition, if the holder is a foreign corporation, it may be subject to a branch profits tax equal to 30% (or lower applicable treaty rate) of its earnings and profits for the taxable year,

S-19


subject to adjustments, that are effectively connected with its conduct of a trade or business in the U.S.. For this purpose, interest will be included in earnings and profits.

        Disposition of Notes.    Subject to the discussion of backup withholding below, the 30% U.S. federal income withholding tax will not apply to any gain that a non-U.S. holder realizes on the sale, exchange, redemption, retirement or other disposition of a note unless (i) that gain is effectively connected with the conduct of a trade or business in the U.S. by the holder or (ii) the holder is an individual who is present in the U.S. for a period or periods aggregating 183 days or more in the taxable year of that disposition and other conditions are met. If (i) applies, the non-U.S. holder will be subject to U.S. federal income tax on the net gain derived from the disposition in the same manner as if the holder were a U.S. person, and if the non-U.S. holder is a corporation, such holder may also be subject to a branch profits tax equal to 30% (or lower applicable treaty rate) as described above.

Information Reporting and Backup Withholding

        U.S. Holders.    In general, information reporting requirements will apply to payments of principal and interest made on the notes to, and to the proceeds of the sale of the notes within the U.S. by certain non-corporate U.S. holders of notes and backup withholding at the applicable rate (currently 28%) will apply to these payments if the U.S. holder (i) fails to provide an accurate taxpayer identification number in the manner required or (ii) is notified by the Internal Revenue Service ("IRS") that it has failed to report all interest and dividends required to be shown on its U.S. federal income tax returns.

        Non-U.S. Holders.    Information returns will be filed with the IRS in connection with payments on the notes, and may be filed in connection with the receipt of proceeds from the sale or other disposition of the notes.

        In general, subject to the discussion above under "Non-U.S. Holders—Payments of Interest," a non-U.S. holder will not be subject to backup withholding with respect to payments that we make to the non-U.S. holder, provided that we do not have actual knowledge that the holder is a U.S. person and the holder has given us the statement or provided the certifications described above under "Non-U.S. Holders—Payments of Interest."

        In addition, subject to the discussion above under "Non-U.S. Holders—Disposition of Notes," a non-U.S. holder will not be subject to backup withholding with respect to the proceeds of the sale or other disposition of a note within the U.S. or conducted through certain U.S.-related financial intermediaries if the payor receives the statements or certifications described above and does not have actual knowledge that the holder is a U.S. person, as defined under the Code, or the holder otherwise establishes an exemption.

        Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a holder's U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

        Investors should consult their tax advisors concerning the applicability of the above tax consequences to their particular situations, including the necessity of satisfying various certification requirements, and concerning the applicability of other taxes, such as estate taxes and state and local taxes.

        The underwriting agreement provides that the obligations of the several underwriters to purchase the notes offered hereby are subject to certain conditions and that the underwriters are obligated to purchase all of the notes in the offering if any are purchased. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may be increased or the offering of the notes may be terminated.

        We have been advised by the representatives of the underwriters that the underwriters propose to offer the notes directly to the public at the public offering prices set forth on the cover page of this prospectus supplement and to certain dealers at such prices less a concession not in excess of            % of the principal amount of the notes. The underwriters may allow, and such dealers may re-allow, a concession not in excess of    % of the principal amount of the notes to certain other dealers. After the initial public offering, representatives of the underwriters may change the offering price and other selling terms.

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

        We estimate that our share of the total expenses of this offering, excluding underwriting discounts, will be approximately $150,000.

        The notes are a new issue of securities with no established trading market. The notes will not be listed on any securities exchange or included in any automated dealer quotation system. The underwriters may make a market in the notes after completion of the offering, but will not be obligated to do so and may discontinue any market-making activities at any time without notice. No assurance can be given as to the liquidity of the trading market for the notes or that an active public market for the notes will develop. If an active public trading market for the notes does not develop, the market price and liquidity of the notes may be adversely affected.

        In connection with the offering of the notes, certain of 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, creating a short position. In addition, the underwriters may bid for, and purchase, the 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, but no representation is made hereby of the magnitude of any effect that the transactions described above may have on the market price of the notes. The

S-21


underwriters will not be required to engage in these activities, and may engage in these activities, and may end any of these activities at any time without notice.

        Certain of the underwriters and their affiliates have provided from time to time, and may continue to provide, in the ordinary course of business, investment banking, commercial banking, financial and other services to us, for which we have paid and intend to pay customary fees. In particular, the affiliates of some of the underwriters are participants in our bank credit facility described in our filings with the Securities and Exchange Commission.

        The underwriters will make the notes available for distribution on the Internet through a proprietary website 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 the underwriters and their respective customers and is not a party to any transactions. Market Axess Corporation, a registered broker-dealer, will receive compensation from the underwriters based on transactions the underwriters conduct through the system. The 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.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

        This prospectus and the information incorporated by reference in it include "forward-looking statements" within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act. We intend the forward-looking statements to be covered by the safe harbor provisions for forward-looking statements in these sections.

        All statements regarding our expected financial position and operating results, our business strategy, our financing plans, our future capital requirements, forecasted demographic and economic trends relating to our industry, our ability to complete acquisitions, to realize anticipated cost savings and other benefits from acquisitions and to recover acquisition-related costs, and similar matters are forward-looking statements.

        These statements are subject to known and unknown risks, uncertainties and other factors that could cause our actual results to differ materially from the statements. The forward-looking information is based on various factors and was derived using numerous assumptions.

        In some cases, you can identify these statements by our use of forward-looking words such as "may," "will," "would," "should," "anticipate," "estimate," "expect," "plan," "believe," "predict," "project," "potential" or "intend." You should be aware that these statements only reflect our predictions. Actual events or results may differ substantially.

        Important factors that could cause our actual results to be materially different from our expectations include:

        We undertake no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise.

RISK FACTORS

        Prospective investors should consider carefully the following risk factors before investing in any of the securities offered hereby.

Fluctuations in the foreign currency markets may negatively impact us.

        We are exposed to fluctuations in foreign currency cash flows primarily related to raw material purchases. We are also exposed to fluctuations in the value of foreign currency investments in subsidiaries and unconsolidated affiliates and cash flows related to repatriation of these investments. Additionally, we are exposed to volatility in the translation of foreign currency earnings to U.S. dollars. Primary exposures include the U.S. dollar versus the functional currencies of our major markets (Euro, British pound sterling, Canadian dollar, Australian dollar, Mexican peso, Chinese renminbi and Japanese yen). On occasion, we may enter into forward and option contracts to manage these foreign currency risks. However, these contracts may not effectively limit or eliminate our exposure to a decline in operating results due to foreign currency translation. Therefore, we cannot assure you that future exchange rate fluctuations will not have a negative impact on our business, financial position or operating results.

Increases in interest rates may negatively impact us.

        We had total outstanding short-term borrowings of approximately $140 million at an average interest rate of approximately 2.1% on November 30, 2004. Our policy is to manage our interest costs using a mix of fixed and variable rate debt. We also use interest rate swaps to achieve a desired proportion of fixed and variable rate debt. We utilize derivative financial instruments to enhance our ability to manage risk, including foreign exchange and interest rate exposures that exist as part of our ongoing business operations. We do not enter into contracts for trading purposes, nor are we a party to any leveraged derivative instrument. Our use of derivative financial instruments is monitored through regular communication with senior management and the utilization of written guidelines. However, our use of these instruments may not effectively limit or eliminate our exposure to a decline in operating results due to changes in interest rates. Therefore, we cannot assure you that future interest rate increases will not have a negative impact on our business, financial position or operating results.

Price Fluctuations In The Commodity Markets May Negatively Impact Us.

        We purchase certain raw materials that are subject to price volatility caused by weather and other unpredictable factors. The most significant raw materials are vanilla, cheese, pepper, packaging supplies, garlic, onion and capsicums. While future movements of raw material costs are uncertain, a variety of programs, including strategic raw material purchases, purchases of raw material for future delivery and customer price adjustments, help us address this risk. Generally, we do not use derivatives to manage the volatility related to this risk. Even if we did use such instruments, however, their use might not effectively limit or eliminate our exposure to a decline in operating results due to changes in commodity prices. Therefore, we cannot assure you that future commodity price fluctuations will not have a negative impact on our business, financial position or operating results.

OUR COMPANY

        McCormick & Company, Incorporated is a global leader in the manufacture, marketing and distribution of spices, herbs, seasonings and flavors to the entire food industry.

        We operate in two segments, consumer and industrial, which serve two distinct customer bases. Customers for the consumer segment span a variety of retail outlets and include grocery, drug, dollar and mass merchandise stores. These customers are serviced either through direct shipments or through the food wholesale channel. Products for the consumer segment include spices, herbs, extracts, seasoning blends, sauces, marinades and specialty food products.

        Customers for the industrial segment include food processors and the restaurant industry, supplied both directly and through distributors and warehouse clubs. Products for the industrial segment include spices, blended seasonings, condiments, coatings and compound flavors.

        We have a worldwide workforce of approximately 8,000 employees and our principal executive offices are located at 18 Loveton Circle, Sparks, Maryland 21152 (telephone: 410-771-7301).


RATIO OF EARNINGS TO FIXED CHARGES

        Our ratios of earnings to fixed charges were 6.86, 6.89, 5.94, 4.58 and 5.16 for the years ended November 30, 2004, 2003, 2002, 2001 and 2000, respectively. For the purpose of this ratio, "earnings" consist of income from consolidated operations before income taxes, plus fixed charges (net of capitalized interest), amortization of capitalized interest and dividends from unconsolidated subsidiaries. "Fixed charges" consist of interest, whether expensed or capitalized (including amortization of debt discount), and that portion of rental expense that is representative of interest.


USE OF PROCEEDS

        Except as may be described otherwise in a prospectus supplement, we expect to use the net proceeds from the sale of the Debt Securities under this prospectus for general corporate purposes, including refinancing existing indebtedness, future acquisitions, capital expenditures and working capital. Until we apply the net proceeds for specific purposes, we may invest such net proceeds in short-term or marketable securities.

DESCRIPTION OF DEBT SECURITIES

        The following description of the terms of the Debt Securities sets forth certain general terms and provisions of the Debt Securities to which any prospectus supplement may relate. The Debt Securities are to be issued under an Indenture, dated as of December 5, 2000 (the "Indenture"), between McCormick and SunTrust Bank, a banking corporation organized and existing under the laws of the state of Georgia, as Trustee (the "Trustee"), a copy of which has been filed with the SEC as an exhibit to the registration statement and is incorporated by reference herein. 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 provisions of the Indenture. Capitalized terms are defined in the Indenture unless otherwise defined herein. Wherever particular provisions or defined terms of the Indenture are referred to, such provisions or defined terms are incorporated herein by reference.

General

        The Indenture does not limit the amount of Debt Securities which can be issued thereunder and provides that Debt Securities may be issued thereunder up to the aggregate principal amount which may be authorized from time to time by us. The Debt Securities will be unsecured and will rank on a parity with all other unsecured and unsubordinated indebtedness of McCormick.

        Reference is hereby made to the prospectus supplement relating to the applicable series of Debt Securities for the terms of such Debt Securities, including where applicable:

7

        The Debt Securities may be issued in one or more series with the same or various maturities and will be issued only in full registered form without coupons.

        The terms of the Debt Securities do not afford holders of the Debt Securities protection in the event of a highly leveraged transaction involving McCormick that may adversely affect holders of the Debt Securities.

Transfer and Exchange

        The Debt Securities of a series may be issued in either registered form ("Registered Securities") or global form. See "Book-Entry Securities." Registered Securities may be separated into smaller denominations or combined into larger denominations, as long as the total principal amount is not changed. (Section 3.5 of the Indenture). This is called an "exchange."

        You may transfer Registered Securities of a series and you may exchange Debt Securities of a series at the office of the Trustee. The Trustee will act as our agent for registering Registered Securities in the names of holders and transferring Debt Securities. We may designate someone else to perform this function. Whoever maintains the list of registered holders is called the "Security Registrar." The Security Registrar also will perform transfers. (Section 3.5 of the Indenture)

        You will not be required to pay a service charge to transfer or exchange Debt Securities, but you may be required to pay for any tax or other governmental charge associated with the exchange or transfer. The transfer or exchange will be made only if the Security Registrar is satisfied with your proof of ownership. (Section 3.5 of the Indenture)

        If we designate additional transfer agents, we will name them in the accompanying prospectus supplement. We may cancel the designation of any particular transfer agent. We may also approve a change in the office through which any transfer agent acts.

        If we redeem less than all of the Debt Securities of a redeemable series, we may block the transfer or exchange of Registered Securities during the period beginning 15 days before the day of the

8


selection for redemption of such Registered Securities and ending on the day of the mailing of the relevant notice of redemption in order to freeze the list of holders to prepare the mailing. We may also decline to register transfers or exchanges of Debt Securities selected for redemption, except that we will continue to permit transfers and exchanges of the unredeemed portion of any Debt Security being partially redeemed. (Section 3.5 of the Indenture)

        If the offered Debt Securities are redeemable, we will describe the procedures for redemption in the accompanying prospectus supplement.

        In this "Transfer and Exchange" section of this prospectus, "you" means direct holders and not indirect holders of Debt Securities.

        The Debt Securities of a series may be issued in whole or in part in the form of one or more global securities (the "Global Securities") which will be deposited with, or on behalf of, The Depository Trust Company, New York, New York (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 and not in part, only to another nominee of the Depositary or to a successor of the Depositary or its nominee.

        The Depositary has advised us that it is a limited-purpose trust company organized under the laws of the State of New York, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code and a "clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act. The Depositary was created to hold securities for its participants and to facilitate the clearance and settlement of securities transactions among its participants in such securities through electronic book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates. The Depositary's participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, some of which (and/or their representatives) own the Depositary. Access to the Depositary's book-entry 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. Persons who are not participants may beneficially own securities held by the Depositary only through participants.

        Upon the issuance of Debt Securities by us represented by the Global Securities, the Depositary will credit, on its book-entry registration and transfer system, the respective principal amounts of the Debt Securities represented by such Global Securities to the accounts of participants. The accounts credited shall be initially designated by the underwriters or agents.

        If the Depositary is at any time unwilling or unable to continue as depositary, or if at any time there shall have occurred and be continuing an Event of Default under the Indenture with respect to the Debt Securities, we will issue Debt Securities in certificated form in exchange for the Global Securities. In addition, we may at any time determine not to have Debt Securities represented by the Global Securities, and, in such event will issue Debt Securities in certificated form in exchange for the Global Securities representing such Debt Securities. In any such instance, an owner of a beneficial interest in the Global Securities will be entitled to physical delivery in certificated form of Debt Securities equal in principal amount to such beneficial interest and to have such Debt Securities registered in its name.

Certain of Our Covenants

Limitations on Liens

        Except as described below under "—Exempted Indebtedness", we covenant that we will not, nor will we permit any Restricted Subsidiary to, create, assume or suffer to exist any mortgage, security interest, pledge or lien ("Lien") of or upon any Principal Property or any shares of capital stock or evidences of indebtedness for borrowed money issued by any Restricted Subsidiary and owned by us or any Restricted Subsidiary, without providing that the Debt Securities shall be secured equally and ratably by such Lien with any and all other indebtedness or obligations thereby secured, so long as such indebtedness or obligations shall be so secured.

Exempted Indebtedness

        Notwithstanding the limitations on Liens and sale and leaseback transactions outlined above, we or any Restricted Subsidiary may create, assume or suffer to exist Liens or enter into sale and leaseback transactions not otherwise permitted as described above provided that at the time of such event, and after giving effect thereto, the sum of outstanding indebtedness for borrowed money incurred after the date of the Indenture and secured by Liens not otherwise permitted as set forth above plus the Attributable Debt in respect of such sale and leaseback transactions entered into after the date of the Indenture not otherwise permitted as set forth above does not exceed 15% of Consolidated Net Tangible Assets properly appearing on a consolidated balance sheet of McCormick.

Events of Default

        An Event of Default with respect to the Debt Securities is defined in the Indenture as being:

        The Indenture provides that if an Event of Default under clause (i), (ii) or (iii) above shall have occurred and be continuing, either the Trustee or the holders of not less than 25% in principal amount of the Debt Securities may declare the principal of all the Debt Securities, together with any accrued interest, to be due and payable immediately. (Sections 5.2 and 5.13 of the Indenture).

        If an Event of Default under clause (iv) above shall have occurred and be continuing, then the principal of all the Debt Securities, together with any accrued interest, will be due and payable immediately without any declaration or other act on the part of the Trustee or any holder of a Debt Security. Upon certain conditions such declaration (including a declaration caused by a default in the payment of principal or interest, the payment for which has subsequently been provided) may be annulled by the holders of a majority in principal amount of the Debt Securities. (Sections 5.2 and 5.13 of the Indenture).

        In addition, prior to the declaration of the acceleration of the maturity of the Debt Securities, past defaults may be waived by the holders of a majority in principal amount of the Debt Securities, except a default in the payment of principal of or interest on any Debt Security or in respect of a covenant or provision of the Indenture which cannot be modified or amended without the approval of the holder of each Debt Security. (Sections 5.2 and 5.13 of the Indenture).

        The Indenture contains a provision entitling the Trustee, subject to the duty of the Trustee during default to act with the required standard of care, to be indemnified by the holders of Debt Securities issued thereunder before proceeding to exercise any right or power under the Indenture at the request of the holders of such Debt Securities. (Section 6.3 of the Indenture).

        The Indenture also provides that the holders of a majority in principal amount of the Outstanding Securities of a particular series issued thereunder and affected (each series voting as a separate class) 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 the Trustee, with respect to the Debt Securities of such series. (Section 5.12 of the Indenture).

        The Indenture contains a covenant that McCormick will file annually with the Trustee a certificate as to the absence of any default or specifying any default that exists. (Section 10.9 of the Indenture).

Covenant Defeasance
