ELI LILLY AND COMPANY

We are a worldwide research-based pharmaceutical company. We were incorporated in 1901 in Indiana to succeed to the drug manufacturing business founded in Indianapolis, Indiana, in 1876 by Colonel Eli Lilly. We discover, develop, manufacture and market products in a single business segment—human pharmaceutical products. Our purpose is to unite caring with discovery to create medicines that make life better for people around the world. Most of the products that we sell today were discovered or developed by our own scientists, and our long-term success depends on our ability to continually discover or acquire, develop and commercialize innovative medicines. We manufacture and distribute our products through facilities in the United States, including Puerto Rico, and in Europe and Asia. Our products are sold in approximately 105 countries.

Our corporate offices are located at Lilly Corporate Center, Indianapolis, Indiana 46285, our telephone number is (317) 276-2000 and our website is www.lilly.com. We have included our website address in this prospectus supplement solely as an inactive textual reference and the information contained in, or that can be accessed through, our website is not a part of, or incorporated by reference in, this prospectus supplement.

RISK FACTORS

Your investment in the notes involves risks. You should consider carefully the risks discussed under “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 and our other filings with the SEC that are incorporated by reference into this prospectus supplement and the accompanying prospectus. It is possible that our business, financial condition, liquidity, cash flows, results of operations, reputation and prospects could be materially adversely affected by any of these risks or additional risks and uncertainties not presently known to us or that we currently believe to be immaterial.

This prospectus supplement and the documents incorporated by reference herein also contain forward-looking statements and estimates that involve risks and uncertainties. Our actual results could differ materially from those anticipated in the forward-looking statements as a result of specific factors, including those described in our filings with the SEC that are incorporated by reference herein. See “Special Note Regarding Forward-Looking Statements” in this prospectus supplement and the accompanying prospectus, “Forward-Looking Statements” in our Annual Report on Form 10-K and similar sections in other filings with the SEC that are incorporated by reference herein.

S-5

USE OF PROCEEDS

We estimate that the net proceeds from the sale of the notes will be approximately $    after deduction of the underwriting discount and before deduction of the estimated expenses of the offering.

We expect to use a portion of the net proceeds from the sale of the notes to fund the consideration payable in connection with the pending acquisition of Morphic Holding, Inc. (“Morphic”) and the fees and expenses in connection therewith. We expect to use any remaining net proceeds from the sale of the notes for general corporate purposes, which may include the repayment of outstanding commercial paper. As of August 12, 2024, the weighted average interest rate of our outstanding commercial paper borrowings was approximately 5.34% per annum and the weighted average maturity was approximately 24 days from issuance. Prior to such uses, we may temporarily invest the net proceeds in marketable securities and short-term investments.

This prospectus supplement is not an offer to purchase or a solicitation of an offer to sell any shares of Morphic common stock, nor is it a substitute for the tender offer materials that have been filed with the SEC in connection with the pending acquisition of Morphic.

S-6

DESCRIPTION OF THE NOTES

The following summary describes certain terms of the    % notes due 20  (the “  % notes”), the   % notes due 20  (the “  % notes”), the   % notes due 20  (the “  % notes”), the   % notes due 20  (the “  % notes”) and the   % notes due 20  (the “  % notes” and, unless the context otherwise requires, collectively with the   % notes, the   % notes, the   % notes and the   % notes, the “notes,” respectively, and supplements, and to the extent inconsistent replaces, the description of the general terms of the debt securities included in the accompanying prospectus. Each series of notes will be a single series of debt securities issued under an indenture, dated as of February 1, 1991 (the “Indenture”), between us and Deutsche Bank Trust Company Americas (as successor to Citibank, N.A.), as trustee. The following summary of the notes does not purport to be complete and is subject to, and is qualified in its entirety by reference to, the actual provisions of the notes and the Indenture. As used in this section, unless otherwise indicated, all references to “we,” “us,” “our” and “Eli Lilly” refer only to Eli Lilly and Company and not to any of our subsidiaries.

General

The notes will be our unsecured and unsubordinated obligations and will rank equally with all of our other unsecured and unsubordinated indebtedness. The notes will be issued in fully registered form only, in minimum denominations of $2,000 and integral multiples of $1,000 in excess of that amount.

We will issue $    in aggregate principal amount of   % notes, $    in aggregate principal amount of   % notes, $    in aggregate principal amount of   % notes, $    in aggregate principal amount of   % notes and $    in aggregate principal amount of   % notes and, except as contemplated below under “—Optional Redemption,” the   % notes will mature on      , 20 , the   % notes will mature on      , 20 , the   % notes will mature on      , 20 , the   % notes will mature on      , 20  and the   % notes will mature on      , 20 .

However, we may, without the consent of the holders of notes, issue additional debt securities having the same ranking, interest rate, maturity, redemption provisions and other terms as the notes of a particular series. Any additional debt securities having such similar terms, together with the notes of such series, will constitute a single series of debt securities under the Indenture. If, however, such additional debt securities are not fungible with the notes for U.S. federal income tax purposes, such additional debt securities will have one or more separate CUSIP numbers.

We will pay interest on the notes at the rates stated in the table below, semi-annually in arrears, on     and     of each year, commencing on      , 2025, to the persons in whose names such notes are registered at the close of business on     or    , respectively, as the case may be (whether or not a business day), immediately preceding the relevant interest payment date.

Interest payments for the notes will include accrued interest from, and including, the date of issuance or from, and including, the last date in respect of which interest has been paid or duly provided for, as the case may be, to, but excluding, the applicable interest payment date or the stated maturity date or the date of earlier redemption, as the case may be. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

S-7

If any interest payment date falls on a day that is not a business day, we will make the required interest payment on the next business day, and no interest on such payment will accrue for the period from and after such interest payment date. Similarly, if the stated maturity date or the date of earlier redemption, as the case may be (a “maturity date”), of the notes falls on a day that is not a business day, we will make the required payment of principal, premium, if any, and interest, if any, on the next succeeding business day, and no interest on such payment will accrue for the period from and after such maturity date.

As used in this prospectus supplement, “business day” means any day, other than a Saturday or a Sunday, that is neither a legal holiday nor a day on which banking institutions are authorized or required by law or regulation to close in the City of New York, New York.

Optional Redemption

Prior to the applicable Par Call Date, we may redeem the notes of any series at our option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(1) (a) the sum of the present values of the remaining scheduled payments of principal and interest on the notes being redeemed discounted to the redemption date (assuming the notes being redeemed matured on the applicable Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate, plus     basis points in the case of the   % notes,     basis points in the case of the    % notes,     basis points in the case of the   % notes,     basis points in the case of the    % notes or     basis points in the case of the   % notes, less (b) interest accrued to the redemption date, and

(2) 100% of the principal amount of the notes being redeemed on such redemption date,

plus, in each case, accrued and unpaid interest thereon to, but excluding, the redemption date.

In addition, on or after the applicable Par Call Date, we may redeem the applicable series of notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of such series of notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the redemption date.

“Par Call Date” means, with respect to the   % notes,   , 20  (   months prior to the maturity date of the   % notes), with respect to the   % notes,   , 20  (   months prior to the maturity date of the  % notes), with respect to the   % notes,   , 20  (   months prior to the maturity date of the  % notes), with respect to the   % notes,   , 20  (   months prior to the maturity date of the   % notes), and with respect to the   % notes,   , 20  (   months prior to the maturity date of the   % notes).

“Treasury Rate” means, with respect to any redemption date for any series of notes prior to the applicable Par Call Date, the yield determined by us in accordance with the following two paragraphs.

The Treasury Rate shall be determined by us after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities—Treasury constant maturities—Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, we shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the applicable Par Call Date (the “Remaining Life”); or (2) if there is no such

S-8

Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to the applicable Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 TCM is no longer published, we shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the applicable Par Call Date. If there is no United States Treasury security maturing on the applicable Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the applicable Par Call Date, one with a maturity date preceding the applicable Par Call Date and one with a maturity date following the applicable Par Call Date, we shall select the United States Treasury security with a maturity date preceding the applicable Par Call Date. If there are two or more United States Treasury securities maturing on the applicable Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, we shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

Our actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

Notwithstanding the foregoing, installments of interest on notes that are due and payable on an interest payment date falling on or prior to a redemption date will be payable on such interest payment date to the registered holders as of the close of business on the relevant record date immediately preceding such interest payment date.

Notice of any redemption will be mailed (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each registered holder of notes being redeemed. Subject to any delay in the redemption date or rescission of the notice of redemption described below, once notice of redemption is mailed, the notes called for redemption will become due and payable on the applicable redemption date. Any notice of redemption may, at our discretion, be subject to one or more conditions precedent, including completion of a corporate transaction. In such event, the related notice of redemption will describe each such condition and, if applicable, will state that, at our discretion, the redemption date may be delayed until such time (including more than 60 days after the notice of redemption was given) as any or all such conditions are satisfied (or waived by us in our sole discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions have not been satisfied (or waived by us in our sole discretion) by the redemption date, or by the redemption date as so delayed. If any such redemption has been rescinded or delayed, we will provide written notice to the trustee prior to the close of business two business days before the redemption date and, upon receipt, the trustee will provide such notice to each registered holder.

If fewer than all of the notes of a particular series are being redeemed, selection of the notes being redeemed will be made pro rata, by lot or by such other method as the trustee in its sole discretion deems appropriate and

S-9

fair. No notes of a principal amount of $2,000 or less will be redeemed in part. If any note is being redeemed in part only, the notice of redemption that relates to the note will state the portion of the principal amount of the note being redeemed. Except in the case of global notes, 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. Notwithstanding the foregoing, for so long as the notes are held by The Depository Trust Company (“DTC”) (or another depositary), the redemption of the notes shall be done in accordance with the policies and procedures of the depositary. Before any redemption date, we will deposit with a paying agent (or the trustee) money sufficient to pay the redemption price of the notes of the particular series being redeemed on that date.

Unless we default in payment of the redemption price therefor, on and after the redemption date, interest will cease to accrue on the notes or any portions of the notes called for redemption. In addition, we may at any time purchase the notes by tender, in the open market or by private agreement, subject to applicable laws.

The notes will not be entitled to the benefit of any mandatory redemption or sinking fund provisions.

Book-Entry Notes

The information in “Book-Entry Notes” concerning DTC and DTC’s book-entry system, as well as information regarding Euroclear and Clearstream (each as defined below), has been obtained from sources that we believe to be reliable, but we take no responsibility for its accuracy or completeness. This information is not intended to serve as a representation, warranty or contract modification of any kind. We assume no responsibility for the performance by DTC, Euroclear, Clearstream or their respective participants of their respective obligations, including obligations that they have under the rules and procedures that govern their operations.

The Depository Trust Company

Except under the limited circumstances described below, all notes will be book-entry notes. This means that the actual purchasers of the notes will not be entitled to have the notes registered in their names and will not be entitled to receive physical delivery of the notes in definitive (paper) form. Instead, upon issuance, each series of notes will be represented by one or more fully registered global notes.

Each global note will be deposited with, or on behalf of, DTC, a securities depositary, and will be registered in the name of Cede & Co., as DTC’s nominee, or such other name as may be requested by an authorized representative of DTC. No global note representing book-entry notes may be transferred except as a whole by DTC to a nominee of DTC or by a nominee of DTC to DTC or another nominee of DTC. DTC will be the only owner and sole registered holder of the notes for purposes of the Indenture. Purchasers may elect to hold interests in the global notes through either DTC (in the United States) or through Clearstream Banking, société anonyme (“Clearstream”), or the Euroclear System (“Euroclear”) (outside the United States) if they are participants in such systems, or indirectly through organizations that are participants in such systems.

Purchases of the notes under the DTC system must be made by or through direct participants, which will receive a credit for the notes in DTC’s records. The ownership interest of each actual purchaser of notes, which we refer to as the “beneficial owner,” will in turn be recorded in the direct and indirect participants’ records. The deposit of the global notes with DTC and their registration in the name of DTC’s nominee will not affect beneficial ownership and is performed merely to facilitate subsequent transfers of the notes. The book-entry system eliminates the need for physical movement of securities certificates. The laws of some jurisdictions, however, may require some purchasers to take physical delivery of notes in definitive form. These laws may impair the ability of holders to transfer book-entry notes.

DTC has advised us that it 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

S-10

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 deposit with it. DTC also facilitates the post-trade settlement among its participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in its participants’ accounts. DTC’s participants include underwriters, including the underwriters in this offering, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Clearstream and Euroclear, which are discussed in more detail below, are indirect participants in the DTC system. The rules applicable to DTC and its participants are on file with the SEC.

Because DTC or its nominee will be the only registered holder of the global notes, Clearstream and Euroclear will hold positions through their respective U.S. depositaries, which in turn will hold positions in the records of DTC. For information on how accounts of ownership of notes held through DTC are recorded, please refer to “Description of Securities—Description of Debt Securities—Global Securities” in the accompanying prospectus.

In this prospectus supplement, unless and until notes in definitive form are issued to the beneficial owners as described below, all references to “holders” of notes shall mean DTC or its nominee. We, the trustee and any paying agent, transfer agent or registrar may treat DTC or its nominee as the only owner and sole registered holder of the notes for all purposes.

We will make all payments of principal of and premium, if any, and interest on our notes to DTC or its nominee by wire transfer. We will send all required reports and notices solely to DTC or its nominee as long as DTC or its nominee is the sole registered holder of the notes. DTC and its participants are generally required by law to receive and transmit all payments, notices and directions from us and the trustee to beneficial owners of book-entry notes through a chain of intermediaries. Beneficial owners of book-entry notes will not receive written confirmation from DTC of their purchases. However, they are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the participants or indirect participants through which they entered into the transaction.

Similarly, we and the trustee will accept notices and directions solely from DTC or its nominee. Therefore, in order to exercise any rights as a holder of notes under the Indenture, each person owning a beneficial interest in the notes must rely on the procedures of DTC and, in some cases, Clearstream or Euroclear. If the beneficial owner is not a participant in the applicable system, then it must rely on the procedures of the participant through which that person owns its interest. DTC has advised us that it will take actions under the Indenture only at the direction of its participants, which in turn will act only at the direction of the beneficial owners. Some of these actions, however, may conflict with actions DTC takes at the direction of other participants and beneficial owners.

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

Beneficial owners may experience delays in receiving payments in respect of their notes since such payments will initially be made to DTC and must then be transferred through the chain of intermediaries to each beneficial owner’s account. None of us, the trustee or any of our or their agents will be liable for the accuracy of, or responsible for maintaining, supervising or reviewing, the records of Clearstream or Euroclear or any participant’s records relating to book-entry notes. In addition, none of us, the trustee or any of our or their agents will be responsible or liable for payments made on account of the book-entry notes.

Clearstream

Clearstream is incorporated under the laws of Luxembourg as a professional depositary. Clearstream holds securities for its participating organizations (“Clearstream participants”) and facilitates the clearance and

S-11

settlement of securities transactions between Clearstream participants through electronic book-entry changes in accounts of Clearstream participants, thereby eliminating the need for physical movement of certificates. Clearstream provides to its participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in several countries. Clearstream has also established an electronic bridge with Euroclear to facilitate settlement of trades between Clearstream and Euroclear.

As a licensed credit institution in Luxembourg and a securities settlement system in which the Luxembourg Central Bank participates, Clearstream is supervised by the Luxembourg Commission for the Supervision of the Financial Sector (Commission de Surveillance du Secteur Financier). Clearstream participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations and may include the underwriters in this offering. Other institutions that clear through or that maintain a custodial relationship with a Clearstream participant may obtain indirect access to Clearstream.

Euroclear

Euroclear was created in 1968 to hold securities for its participating organizations (“Euroclear participants”) and to clear and settle transactions between Euroclear participants and participants of certain other securities intermediaries through simultaneous electronic book-entry delivery against payment, thus eliminating the need for physical movement of certificates and the risk from lack of simultaneous transfers of securities and cash. Euroclear provides various other services, including securities lending and borrowing, and interfaces with domestic markets in several countries.

Euroclear provides various other services, including securities lending and borrowing, and interfaces with domestic markets in several countries.

Euroclear is operated by Euroclear Bank S.A./N.V. (the “Euroclear Operator”). All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator.

Euroclear participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the underwriters in this offering. In addition, indirect access to Euroclear is available to other firms that clear through or maintain a custodial relationship with a Euroclear participant, either directly or indirectly.

Securities clearance accounts and cash accounts with the Euroclear Operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System and applicable Belgian law (collectively, the “Terms and Conditions”). The Terms and Conditions govern securities clearance accounts and cash accounts with Euroclear. Specifically, the Terms and Conditions govern:

All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. Euroclear acts under the Terms and Conditions only on behalf of Euroclear participants and has no record of or relationship with persons holding securities through Euroclear participants.

Global Clearance and Settlement Procedures

Initial settlement for the notes will be made in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way, in accordance with DTC’s rules, and will be settled in

S-12

immediately available funds using DTC’s same-day funds settlement system. Secondary market trading between Clearstream participants and Euroclear participants will occur in the ordinary way, in accordance with the applicable rules and operating procedures of Clearstream and Euroclear, and will be settled using the procedures applicable to conventional eurobonds in immediately available funds.

Cross-market transfers between persons holding directly or indirectly through DTC, on the one hand, and directly or indirectly through Clearstream or Euroclear participants, on the other, will be effected through DTC, in accordance with DTC’s rules, on behalf of the relevant European international clearing system by the U.S. depositaries. However, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in this system in accordance with its rules and procedures and within its established deadlines in European time zones. The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to its U.S. depositary to take action to effect final settlement on its behalf by delivering or receiving notes in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream participants and Euroclear participants may not deliver instructions directly to DTC.

Because of time zone differences, credits of notes received in Clearstream or Euroclear as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and will be credited the business day following the DTC settlement date. These credits or any transactions in such notes settled during such processing will be reported to the relevant Euroclear or Clearstream participants on that business day. Cash received in Clearstream or Euroclear as a result of sales of notes by or through a Clearstream participant or a Euroclear participant to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or Euroclear cash account only as of the business day following settlement in DTC.

Although we expect that DTC, Clearstream and Euroclear have agreed to the foregoing procedures to facilitate transfers of notes among participants of DTC, Clearstream and Euroclear, the information set forth in this section is subject to any changes or reinterpretations of the rules, regulations and procedures of DTC, Clearstream and Euroclear that are currently in effect. Investors wishing to use the facilities of any of DTC, Clearstream or Euroclear are advised to confirm the continued applicability of the rules, regulations and procedures of DTC, Clearstream or Euroclear.

Payments

We will make all payments of principal of and premium, if any, and interest on book-entry notes to DTC or its nominee. Upon receipt of any such payment, DTC will immediately credit the accounts of its participants on its book-entry registration and transfer system. DTC will credit those accounts in proportion to the participants’ respective beneficial interests in the principal amount of the global note as shown in the records of DTC. Payments by participants to beneficial owners of book-entry notes will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of those participants.

Payments on book-entry notes held beneficially through Clearstream or Euroclear will be credited to their respective participants in accordance with their respective rules and procedures, to the extent received by their respective U.S. depositaries.

Definitive Notes and Paying Agents

Under the circumstances described in the last paragraph under “Description of Securities—Description of Debt Securities—Global Securities” of the accompanying prospectus, beneficial owners of the notes will be notified through the chain of intermediaries that definitive notes are available. Beneficial owners of book-entry notes will then be entitled (1) to receive physical delivery of notes in definitive form equal in principal amount to

S-13

their beneficial interest and (2) to have notes in definitive form registered in their names. The notes in definitive form will be issued in minimum denominations of $2,000 and integral multiples of $1,000 in excess of that amount.

Notes in definitive form will be registered in the name or names of the person or persons DTC specifies in a written instruction to the registrar of the notes. DTC may base its written instruction upon directions it receives from its participants. Thereafter, the holders of the notes in definitive form will be recognized as the “holders” of the notes under the Indenture. The Indenture provides for the replacement of a mutilated, lost, stolen or destroyed definitive note, so long as the applicant furnishes to us and the trustee such securities or indemnity and such evidence of ownership as we and the trustee may require.

In the event that notes in definitive form are issued, the holders of such notes will be able to receive payments of principal of and premium, if any, and interest on their notes at the office of our paying agent. Our paying agent will initially be Deutsche Bank Trust Company Americas, currently located at 1 Columbus Circle, 17th Floor, New York, New York 10019, and Deutsche Bank Trust Company Americas will initially act as registrar for the notes. We may, at any time, designate additional paying agents or rescind the designations or approve a change in the offices where they act. Payments due on the maturity date of a note in definitive form may be made only against presentation and surrender of such note to one of our paying agents. We may make payments due on an interest payment date for a note in definitive form by mailing a check to the address of the holder of such note appearing in the register of note holders maintained by the registrar.

In the event that notes in definitive form are issued, the holders of such notes will be able to transfer their notes, in whole or in part, by surrendering such notes for registration of transfer at the office of Deutsche Bank Trust Company Americas, duly endorsed by or accompanied by a written instrument of transfer in form satisfactory to us and the registrar. A form of such instrument of transfer will be obtainable at the offices of Deutsche Bank Trust Company Americas. Upon surrender, we will execute, and the trustee will authenticate and deliver, new notes of the same series and like tenor and terms to the designated transferee in the principal amount being transferred, and a new note of the same series and like tenor and terms for any principal amount not being transferred will be issued to the transferor. We will not charge any fee for the registration of transfer or exchange, except that we may require the payment of a sum sufficient to cover any applicable tax or other governmental charge payable in connection with the transfer.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following describes the material U.S. federal income tax consequences of acquiring, owning and disposing of our notes. This discussion is based on the Internal Revenue Code of 1986, as amended (the “Code”), Treasury regulations thereunder, and administrative and judicial interpretations thereof, in each case as in effect on the date hereof. These authorities may change or be subject to differing interpretations, possibly on a retroactive basis, so as to result in U.S. federal income tax consequences different from those discussed below. This discussion does not address any other U.S. federal tax considerations (such as gift or estate tax) or any state, local or non-U.S. tax considerations.

We have not sought, and will not seek, any ruling from the Internal Revenue Service (the “IRS”) with respect to the statements made and the conclusions reached in this summary. We cannot assure you that the IRS will agree with such statements and conclusions, or that the IRS will not assert, or that a court would not sustain, a challenge to one or more of the tax consequences described below.

This discussion applies only to beneficial owners that acquire our notes upon original issuance and at the initial offering price and that hold our notes as capital assets for U.S. federal income tax purposes. It assumes that the initial offering price is the “issue price” of our notes for U.S. federal income tax purposes. In addition, it does not address all U.S. federal income tax consequences that may be relevant to a particular holder subject to special rules, including, without limitation, banks, insurance companies and other financial institutions, real estate investment trusts, regulated investment companies, partnerships or other entities or arrangements treated as partnerships for U.S. federal income tax purposes, tax-exempt entities and governmental organizations, brokers, traders and dealers in securities that elect to use a mark-to-market method of tax accounting for their securities, U.S. expatriates, persons holding the notes as part of a hedging or conversion transaction or a straddle, tax-qualified retirement plans, persons subject to special tax accounting rules as a result of any item of gross income with respect to our notes being taken into account in an “applicable financial statement” (as defined in the Code), alternative minimum tax, or U.S. Holders (as defined below) that have a functional currency other than the U.S. dollar.

If a partnership, including any entity or arrangement 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. Such partnership and its partners should consult their tax advisors about the U.S. federal income tax consequences of acquiring, owning and disposing of our notes.

Prospective investors are urged to consult their own tax advisors as to the particular U.S. federal income and other tax consequences to them of the acquisition, ownership and disposition of the notes as well as any tax consequences under state, local and foreign tax laws, and the possible effects of changes in tax laws.

U.S. Federal Income Taxation of U.S. Holders

The following describes the material U.S. federal income tax consequences to a U.S. Holder of acquiring, owning and disposing of our notes. As used herein, a “U.S. Holder” is a beneficial owner of a note that is, for U.S. federal income tax purposes, (1) a citizen or resident of the United States, (2) a domestic corporation, (3) an estate the income of which is subject to U.S. federal income taxation regardless of its source or (4) a trust if (i) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control all substantial decisions of the trust or (ii) the trust has a valid election in effect under applicable Treasury regulations to be treated as a United States person. If you are not a U.S. Holder, this subsection does not apply to you and you should refer to the subsection “—U.S. Federal Income Taxation of Non-U.S. Holders” below.

Stated Interest

It is expected, and the following discussion assumes, that the notes will be issued without original issue discount for U.S. federal income tax purposes. Accordingly, interest on the notes offered hereby generally will be

S-15

taxable to a U.S. Holder as ordinary income at the time it accrues or is actually or constructively received in accordance with the U.S. Holder’s method of accounting for U.S. federal income tax purposes.

Taxable Disposition of a Note

Upon the sale, exchange, redemption, retirement at maturity or other taxable disposition of a note, a U.S. Holder generally will recognize gain or loss equal to the difference between (1) the sum of cash and the fair market value of other property received on such disposition (less such cash or property attributable to accrued but unpaid interest not previously included in income, which will be taxable as ordinary interest income), and (2) the U.S. Holder’s adjusted tax basis in the note. A U.S. Holder’s adjusted tax basis in a note generally will equal the U.S. Holder’s initial investment in the note. This gain or loss generally will be capital gain or loss, and will be long-term capital gain or loss if the U.S. Holder has a holding period of more than one year. Long-term capital gain of a non-corporate U.S. Holder generally is taxed at a lower maximum marginal tax rate than that applicable to ordinary income.

Backup Withholding and Information Reporting

U.S. Holders generally will be required to supply a social security number or other taxpayer identification number along with certain certifications under penalties of perjury in order to avoid backup withholding with respect to interest paid on a note and the proceeds of a sale or other disposition of a note. In addition, such payments generally will be subject to information reporting.

Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against such U.S. Holder’s federal income tax liability and may entitle such U.S. Holder to a refund, provided that the required information is timely furnished to the IRS.

Net Investment Income Tax

Additional net investment income tax (commonly referred to as “Medicare tax”) at a rate of 3.8% is imposed on the net investment income of certain individuals, estates and trusts. For these purposes, “net investment income” generally includes interest on and capital gains from the sale or other disposition of securities like the notes, subject to certain exceptions. A U.S. Holder that is an individual, estate or trust is urged to consult its tax advisor regarding the applicability of the net investment income tax to its income and gains in respect of the notes.

U.S. Federal Income Taxation of Non-U.S. Holders

The following describes the material U.S. federal income tax consequences to a Non-U.S. Holder of acquiring, owning and disposing of our notes. A “Non-U.S. Holder” is a beneficial owner of a note that is, for U.S. federal income tax purposes, a nonresident alien individual, a foreign corporation or a foreign trust or estate. If you are a U.S. Holder, this subsection does not apply to you, and you should refer to the subsection “—U.S. Federal Income Taxation of U.S. Holders” above.

Interest on the Notes

Except in the circumstances described below under “—Information Reporting and Backup Withholding” and “—FATCA Withholding,” a Non-U.S. Holder generally will not be subject to U.S. federal income tax or withholding tax on payments of interest on our notes, if the interest is not effectively connected with the Non-U.S. Holder’s conduct of a trade or business in the United States and the Non-U.S. Holder (1) does not own, actually or constructively, 10% or more of the total combined voting power of all classes of our stock entitled to vote, (2) is not, for U.S. federal income tax purposes, a controlled foreign corporation that is related to us through stock ownership, and (3) certifies under penalty of perjury (usually by providing an IRS Form W-8BEN or W-8BEN-E) that it is not a United States person.

S-16

If a Non-U.S. Holder does not satisfy the requirements described in the preceding paragraph, payments of interest on our notes will be subject to U.S. federal withholding tax at a rate of 30% (or, if appropriate certification is provided, a lower rate if so specified in an applicable tax treaty), unless the holder provides a properly executed IRS Form W-8ECI stating that interest paid on the note is not subject to withholding tax because it is effectively connected with the holder’s conduct of a trade or business in the United States (and, if an income tax treaty applies, is attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder in the United States).

If a Non-U.S. Holder is engaged in a trade or business in the United States, and if interest on the note is effectively connected with the conduct of this trade or business (and, if an income tax treaty applies, is attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder in the United States), the Non-U.S. Holder, although exempt from U.S. federal withholding tax, will generally be taxed on a net income basis in the same manner as a U.S. Holder. In addition, effectively connected interest of a corporate Non-U.S. Holder may also be subject to an additional branch profits tax at a rate of 30% (or a lower rate if so specified by an applicable tax treaty).

Non-U.S. Holders are urged to consult their own tax advisors with respect to the U.S. federal, state and local tax consequences of the acquisition, ownership and disposition of our notes.

Sale or Other Taxable Disposition of the Notes

Except in the circumstances described below under “—Information Reporting and Backup Withholding” and “—FATCA Withholding” and except with respect to accrued and unpaid interest, a Non-U.S. Holder generally will not be subject to U.S. federal income tax or withholding tax on any gain recognized on the sale, exchange, redemption, retirement or other taxable disposition of a note, unless:

A Non-U.S. Holder described in the first bullet point above will generally be required to pay U.S. federal income tax on a net income basis, and if the holder is a foreign corporation, it may also be required to pay a branch profits tax at a rate of 30% (or a lower rate if so specified by an applicable tax treaty). A Non-U.S. Holder that is subject to the 183-day rule described above generally will be subject to U.S. federal income tax at a flat rate of 30% (or a reduced rate under an applicable treaty) on the amount by which capital gains allocable to U.S. sources (including gains from the sale, exchange, retirement or other disposition of the note) exceed capital losses allocable to U.S. sources, even though the non-U.S. Holder is not considered a resident alien under the Code.

Information Reporting and Backup Withholding

Except as described below, payments of interest on notes owned by a Non-U.S. Holder, and gross proceeds from the sale or redemption of such notes within the United States or through certain U.S.-related financial intermediaries, generally are subject to information reporting and backup withholding unless the Non-U.S. Holder, as a beneficial owner, certifies under penalty of perjury that it is not a United States person (usually by providing an IRS Form W-8BEN or W-8BEN-E) or otherwise establishes an exemption and the applicable withholding agent does not have actual knowledge or reason to know that such holder is a “United States person”.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against such Non-U.S. Holder’s U.S. federal income tax liability provided the required information is timely furnished to the IRS.

S-17

Payments of interest on a note to a Non-U.S. Holder and the amount of any U.S. federal tax withheld from such payments generally must be reported annually to the IRS and to such Non-U.S. Holder, regardless of whether withholding is required. Copies of the information returns reporting such interest payments and any withholding may also be made available to the tax authorities in the country in which the Non-U.S. Holder resides under provisions of an applicable income tax treaty or other intergovernmental agreement.

FATCA Withholding

Sections 1471 through 1474 of the Code and applicable Treasury regulations thereunder (commonly referred to as “FATCA”) impose a 30% withholding tax on “withholdable payments” made to a foreign entity unless the foreign entity is:

Withholdable payments include interest paid with respect to the notes and the gross proceeds of the sale or other taxable disposition of the notes. However, proposed Treasury regulations have been issued that, if finalized, will eliminate the 30% withholding tax that would have applied to payments of gross proceeds from the sale, exchange or other disposition of the notes. According to the preamble to the proposed regulations, taxpayers may rely upon the relevant provisions of the proposed regulations until the issuance of final regulations. A withholding agent such as a broker, and not Eli Lilly, will generally determine whether or not to implement gross proceeds FATCA withholding.

Prospective investors are urged to consult with their own tax advisors regarding the consequences, including the certification requirements, of the FATCA provisions and any applicable intergovernmental agreement with respect to FATCA in light of their particular circumstances.

UNDERWRITING

BNP Paribas Securities Corp., Citigroup Global Markets Inc., Goldman Sachs & Co. LLC, J.P. Morgan Securities LLC and Morgan Stanley & Co. LLC are acting as representatives of the underwriters named below.

Subject to the terms and conditions stated in the underwriting agreement dated the date of this prospectus supplement, each underwriter named below has severally agreed to purchase, and we have agreed to sell to that underwriter, the principal amount of the notes of each series set forth opposite such underwriter’s name.

The underwriting agreement provides that the obligations of the underwriters to purchase the notes included in this offering are subject to approval of legal matters by counsel and to other conditions. The underwriters are obligated to purchase all of the notes if they purchase any of the notes. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders of notes in whole or in part.

The underwriters may offer some of the notes directly to the public at the respective public offering prices set forth on the cover page of this prospectus supplement and some of the notes to dealers at the respective public offering price less a concession not to exceed the rates (as a percentage of the principal amount) in the table immediately below. The underwriters may allow, and dealers may reallow, a concession not to exceed the rates (as a percentage of the principal amount) set forth in the table below, on sales to other dealers. After the initial offering of the notes of a particular series to the public, the representatives may change the related public offering price and concession.

The following table shows the underwriting discount that we have agreed to pay to the underwriters in connection with this offering.

S-19

In connection with this offering, the representatives, on behalf of the underwriters, may purchase and sell notes in the open market. These transactions may include over-allotment, syndicate covering transactions and stabilizing transactions. Over-allotment involves syndicate sales of notes of a particular series in excess of the principal amount of notes of such series to be purchased by the underwriters in this offering, which creates a syndicate short position. Syndicate covering transactions involve purchases of notes of a particular series in the open market after the distribution of such notes has been completed in order to cover syndicate short positions. Stabilizing transactions consist of certain bids or purchases of notes of a particular series made for the purpose of preventing or retarding a decline in the market price of the notes of such series while this offering is in progress.

The underwriters also may impose a penalty bid. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the representatives, in covering syndicate short positions or making stabilizing purchases, repurchase notes originally sold by that syndicate member.

Any of these activities may have the effect of preventing or retarding a decline in the market prices of the notes. They may also cause the prices of the notes to be higher than the prices that otherwise would exist in the open market in the absence of these transactions. The underwriters may conduct these transactions in the over-the-counter market or otherwise. If the underwriters commence any of these transactions, they may discontinue them at any time.

We estimate that our total expenses for this offering (not including the underwriting discount) will be approximately $    million. In connection with this offering, the underwriters have agreed to reimburse us for certain expenses relating to this offering.

We have agreed to indemnify the underwriters and their controlling persons against certain liabilities, including liabilities under the Securities Act, or to contribute to payments they may be required to make because of any of those liabilities.

Relationships

Certain of the underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, and may in the future receive, customary fees and commissions for these transactions.

In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers.

Such investments and securities activities may involve securities or instruments of ours or our affiliates. Certain of the underwriters or their affiliates that have a lending relationship with us routinely hedge, and certain other of the underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby. The underwriters and their affiliates may also make investment recommendations and publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long or short positions in such securities and instruments.

Certain of the underwriters or their respective affiliates may be holders of our commercial paper. If any of the underwriters, together with their respective affiliates, receives at least 5% of the net proceeds from this offering, not including underwriting compensation, as a result of our intended use of the net proceeds from the sale of the notes as described in “Use of Proceeds,” such underwriters will be deemed to have a “conflict of

S-20

interest” within the meaning of Rule 5121 of the Financial Industry Regulation Authority, Inc. (“FINRA Rule 5121”). However, pursuant to FINRA Rule 5121, the appointment of a qualified independent underwriter is not necessary in connection with this offering because the notes are “investment grade rated” as defined by FINRA Rule 5121.

Selling Restrictions

The notes are being offered for sale in jurisdictions where it is lawful to make such offers and sales.

Each of the underwriters has represented and agreed that it has not and will not offer, sell or deliver any of the notes directly or indirectly, or distribute this prospectus supplement or the prospectus or any other offering material relating to the notes, in or from any jurisdiction except under circumstances that will result in compliance with the applicable laws and regulations thereof and that will not impose any obligations on us except as set forth in the underwriting agreement.

Canada

The notes may be sold only to purchasers purchasing, or deemed to be purchasing, as principal that are accredited investors, as defined in National Instrument 45-106 Prospectus Exemptions or subsection 73.3(1) of the Securities Act (Ontario), and are permitted clients, as defined in National Instrument 31-103 Registration Requirements, Exemptions and Ongoing Registrant Obligations. Any resale of the notes must be made in accordance with an exemption from, or in a transaction not subject to, the prospectus requirements of applicable securities laws.

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if this prospectus supplement and the accompanying prospectus (including any amendment thereto) contains a misrepresentation, provided that the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser’s province or territory. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for particulars of these rights or consult with a legal advisor.

Pursuant to section 3A.3 of National Instrument 33-105 Underwriting Conflicts (“NI 33-105”), the underwriters are not required to comply with the disclosure requirements of NI 33-105 regarding underwriter conflicts of interest in connection with this offering.

Prohibition of Sales to European Economic Area (“EEA”) Retail Investors

Each underwriter has represented and agreed that it has not offered, sold or otherwise made available and will not offer, sell or otherwise make available any notes to any retail investor in the EEA. For the purposes of this provision:

S-21

Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

Prohibition of Sales to United Kingdom (“U.K.”) Retail Investors

Each underwriter has represented and agreed that it has not offered, sold or otherwise made available and will not offer, sell or otherwise make available any notes to any retail investor in the U.K. For the purposes of this provision:

Consequently no key information document required by Regulation (EU) No 1286/2014 as it forms part of domestic law by virtue of the EUWA (the “U.K. PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the U.K. has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the U.K. may be unlawful under the U.K. PRIIPs Regulation.

Each underwriter has represented and agreed that:

This prospectus supplement is only for distribution to and directed at: (i) in the U.K., persons having professional experience in matters relating to investments falling within Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005 (as amended) (the “Order”) and high net worth entities falling within Article 49(2)(a) to (d) of the Order; (ii) persons who are outside the U.K.; and (iii) any other person to whom it can otherwise be lawfully distributed (all such persons together being referred to as “Relevant Persons”).

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the information included or incorporated by reference herein and therein include forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act, and are subject to the safe harbor created thereby under the Private Securities Litigation Reform Act of 1995. Forward-looking statements include all statements that do not relate solely to historical or current facts, and generally can be identified by the use of words such as “may,” “believe,” “will,” “expect,” “project,” “estimate,” “intend,” “anticipate,” “plan,” “continue,” or similar expressions or future or conditional verbs.

Forward-looking statements inherently involve many risks and uncertainties that could cause actual results to differ materially from those expressed in forward-looking statements. Where, in any forward-looking statement, we express an expectation or belief as to future results or events, it is based on management’s current plans and expectations, expressed in good faith and believed to have a reasonable basis. However, we can give no assurance that any such expectation or belief will result or will be achieved or accomplished. Investors therefore should not place undue reliance on forward-looking statements. The following include some but not all of the factors that could cause actual results or events to differ materially from those anticipated:

6

Investors should also carefully read the factors described under the section entitled “Risk Factors” and in other cautionary statements in this prospectus and in our Annual Report on Form 10-K for the year ended December 31, 2021 and our other filings with the SEC that are incorporated by reference into this prospectus for a description of certain risks that could, among other things, cause our actual results to differ from those expressed in forward-looking statements.

All forward-looking statements speak only as of the date of this prospectus and are expressly qualified in their entirety by the risk factors and other cautionary statements included in, or incorporated by reference into, this prospectus. Except as is required by law, we expressly disclaim any obligation to publicly release any revisions to forward-looking statements to reflect events after the date of this prospectus.

USE OF PROCEEDS

We intend to use the net proceeds from the sale of the securities for general corporate purposes, unless otherwise specified in the applicable prospectus supplement.

DESCRIPTION OF SECURITIES

This prospectus contains a summary of the common stock, preferred stock, depositary shares, debt securities, warrants, stock purchase contracts and stock purchase units that we may offer, from time to time, in future securities offerings. These summaries are not meant to be a complete description of each security. Certain specific terms of any security to be issued pursuant hereto will be set forth in a related prospectus supplement.

DESCRIPTION OF CAPITAL STOCK

As of the date hereof, our authorized capital stock consists of 3,205,000,000 shares, of which 3,200,000,000 shares are common stock, without par value, and 5,000,000 shares are preferred stock, without par value. As of February 22, 2022, there were 952,347,126 shares of our common stock outstanding. None of our preferred stock was issued and outstanding as of February 22, 2022. All of our issued and outstanding shares of common stock are fully paid and non-assessable.

Common Stock

Dividend Rights. Subject to the dividend rights of the holders of any outstanding shares of preferred stock, the holders of shares of common stock are entitled to receive ratably dividends as may be lawfully declared at any time by the board of directors.

Rights Upon Liquidation. Upon liquidation, dissolution or winding up of our affairs, after payment to the holders of any outstanding shares of preferred stock of the full amount to which they are entitled, the holders of shares of common stock are entitled, to the exclusion of any holders of preferred stock, to share ratably in our assets that are legally available for distribution after satisfaction of our liabilities.

No Conversion, Redemption or Preemptive Rights. Holders of our common stock have no conversion, redemption, preemptive or similar rights.

Voting Rights. Each outstanding share of common stock is entitled to one vote on all matters submitted to a vote of shareholders. Our amended articles of incorporation do not provide for cumulative voting in the election of directors.

Other Provisions. No shares of any class of our capital stock are subject to any sinking fund provisions or to calls, assessments by, or liabilities of our company.

Preferred Stock

Our amended articles of incorporation authorize our board of directors, without further shareholder action, to provide for the issuance of up to 5,000,000 shares of preferred stock, in one or more series, and to fix, by the adoption and filing in accordance with the Indiana Business Corporation Law, or the IBCL, of an amendment or amendments to the amended articles of incorporation, the designations, terms and relative rights and preferences, including the dividend rate, voting rights, conversion rights, redemption and sinking fund provisions and liquidation preferences, of each of these series. We may amend from time to time our amended articles of incorporation to increase the number of authorized shares of preferred stock. Any such amendment would be approved if the votes cast favoring the amendment exceed the votes cast opposing the amendment.

Certain specific terms of any preferred stock that we offer in the future will be described in the applicable prospectus supplement relating to that preferred stock. Investors are urged to carefully review the terms contained in such prospectus supplement, as well as the articles of amendment establishing such terms that we file with the Secretary of State of the State of Indiana and the SEC. Those terms may include:

9

Dividend Rights. The preferred stock will have a preference over the common stock as to the payment of dividends. Before any dividends or distributions (other than dividends or distributions payable in common stock or other stock ranking junior to that series of preferred stock as to dividends and upon liquidation) on the common stock or other stock ranking junior to that series of preferred stock as to dividends and upon liquidation shall be declared and set apart for payment or paid, the holders of shares of each series of preferred stock (unless otherwise set forth in the applicable prospectus supplement) will be entitled to receive dividends when, as and if declared by our board of directors or, if dividends are cumulative, full cumulative dividends for the current and all prior dividend periods. We will pay those dividends either in cash, shares of preferred stock, or otherwise, at the rate and on the date or dates set forth in the applicable prospectus supplement. With respect to each series of preferred stock that has cumulative dividends, the dividends on each share of the series will be cumulative from the date of issue of the share unless some other date is set forth in the prospectus supplement relating to the series. Accruals of dividends will not bear interest. The applicable prospectus supplement will indicate the relative ranking of the particular series of the preferred stock as to the payment of dividends, as compared with then-existing and future series of preferred stock.

Rights Upon Liquidation. The preferred stock of each series will be preferred over the common stock and other stock ranking junior to that series of preferred stock as to assets, so that the holders of that series of preferred stock (unless otherwise set forth in the applicable prospectus supplement) will be entitled to be paid, upon our voluntary or involuntary liquidation, dissolution or winding up, and before any distribution is made to the holders of common stock and other stock ranking junior to that series of preferred stock, the amount set forth in the applicable prospectus supplement. However, in this case the holders of preferred stock of that series will not be entitled to any other or further payment. If upon any liquidation, dissolution or winding up, our net assets are insufficient to permit the payment in full of the respective amounts to which the holders of all outstanding preferred stock are entitled, our entire remaining net assets will be distributed among the holders of each series of preferred stock in amounts proportional to the full amounts to which the holders of each series are entitled, subject to any provisions of any series of preferred stock that rank it junior or senior to other series of preferred stock upon liquidation. The applicable prospectus supplement will indicate the relative ranking of the particular series of the preferred stock upon liquidation, as compared with then-existing and future series of preferred stock.

Conversion, Redemption or Exchange Rights. The shares of a series of preferred stock will be convertible at the option of the holder of the preferred stock, redeemable at our option or the option of the holder, as applicable, or exchangeable at our option, into another security, in each case, to the extent set forth in the applicable prospectus supplement.

Voting Rights. Except as indicated in the applicable prospectus supplement or as otherwise from time to time required by law, the holders of preferred stock will have no voting rights other than those fixed by the board of directors pursuant to Article 7 of our amended articles of incorporation.

Anti-Takeover Effects of Provisions of our Amended Articles of Incorporation and our Bylaws

Our amended articles of incorporation and our bylaws, as currently in effect, contain certain provisions that may be deemed to have an anti-takeover effect and may delay, deter or prevent a tender offer or takeover attempt that a shareholder might consider in its best interest, including those attempts that might result in a premium over the market price for the shares held by shareholders.

Our bylaws provide that special meetings of holders of common stock may be called only by our board of directors or the Chair of the board of directors. Holders of our common stock are not permitted to call a special meeting or to require that our board of directors call a special meeting of shareholders.

Our bylaws establish an advance notice procedure for the nomination, other than by or at the direction of our board of directors, of candidates for election as directors as well as for other shareholder proposals to be considered at annual meetings of shareholders. In general, notice of intent to nominate a director or raise business at such meetings must be received by us not less than 120 days nor more than 180 days prior to the date on which our proxy statement is released to shareholders in connection with the previous year’s annual meeting and must contain certain specified information concerning the person to be nominated or the matters to be brought before the meeting and concerning the shareholder submitting the proposal.

Our amended articles of incorporation provide for our board of directors to be divided into three classes of directors, as nearly equal in number as possible, serving staggered terms of office. Approximately one-third of our board of directors is elected each year to three-year terms of office. In addition, our directors (other than directors appointed by holders of preferred stock) may be removed only for cause and only upon the affirmative vote of holders of at least 80% of our outstanding voting stock.

Our amended articles of incorporation provide that, in addition to any affirmative vote required by law, the affirmative vote of holders of at least 80% of our outstanding voting stock shall be necessary to approve certain major business transactions (such as mergers or asset sales with an interested shareholder or our liquidation), unless approved by our board of directors in the manner prescribed in such articles.

Under Section 23-1-39-1 of the IBCL and our amended articles of incorporation and bylaws, only our board of directors can amend our bylaws, and shareholders do not have the right to amend our bylaws.

The foregoing summary is qualified in its entirety by the provisions of our amended articles of incorporation and our bylaws, as currently in effect, copies of which have been filed with the SEC.

Certain Provisions of the IBCL

As an Indiana corporation, we are governed by the IBCL. Under specified circumstances, the following provisions of the IBCL may delay, prevent or make more difficult certain unsolicited acquisitions or changes in control of us. These provisions also may have the effect of preventing changes in our management. It is possible that these provisions could make it more difficult to accomplish transactions which shareholders may otherwise deem to be in their best interest.

Unanimous Written Consent of Shareholders. Under Chapter 29 of the IBCL, any action required or permitted to be taken by the holders of common stock may be effected only at an annual meeting or special meeting of such holders, and shareholders may act in lieu of such meetings only by unanimous written consent.

Control Share Acquisitions. Under Chapter 42 of the IBCL, an acquiring person or group who makes a “control share acquisition” in an “issuing public corporation” may not exercise voting rights on any “control shares” unless these voting rights are conferred by a majority vote of the disinterested shareholders of the issuing

11

public corporation at a special meeting of those shareholders held upon the request and at the expense of the acquiring person. If control shares acquired in a control share acquisition are accorded full voting rights and the acquiring person has acquired control shares with a majority or more of all voting power, all shareholders of the issuing public corporation have dissenters’ rights to receive the fair value of their shares pursuant to Chapter 44 of the IBCL.

Under the IBCL, “control shares” means shares acquired by a person that, when added to all other shares of the issuing public corporation owned by that person or in respect to which that person may exercise or direct the exercise of voting power, would otherwise entitle that person (directly or indirectly, alone or as part of a group) to exercise or direct the exercise of the voting power of the issuing public corporation in the election of directors within any of the following ranges:

“Control share acquisition” means, subject to specified exceptions, the acquisition, directly or indirectly, by any person of ownership of, or the power to direct the exercise of voting power with respect to, issued and outstanding control shares. For the purposes of determining whether an acquisition constitutes a control share acquisition, shares acquired within 90 days or under a plan to make a control share acquisition are considered to have been acquired in the same acquisition. “Issuing public corporation” means a corporation which has (i) 100 or more shareholders, (ii) its principal place of business or its principal office in Indiana, or that owns or controls assets within Indiana having a fair market value of greater than $1,000,000, and (iii) (A) more than 10% of its shareholders resident in Indiana, (B) more than 10% of its shares owned of record or owned beneficially by Indiana residents or (C) 1,000 shareholders resident in Indiana.

The above provisions do not apply if, before a control share acquisition is made, the corporation’s articles of incorporation or bylaws, including a bylaw adopted by the corporation’s board of directors, provide that they do not apply. Our amended articles of incorporation and our bylaws do not currently exclude us from Chapter 42.

Certain Business Combinations. Chapter 43 of the IBCL restricts the ability of a “resident domestic corporation” to engage in any business combinations with an “interested shareholder” for five years after the date the interested shareholder became such, unless the business combination or the purchase of shares by the interested shareholder on the interested shareholder’s date of acquiring shares is approved by the board of directors of the resident domestic corporation before that date. If the business combination was not previously approved, the interested shareholder may effect a business combination after the five-year period only if that shareholder receives approval from a majority of the disinterested shareholders or the offer meets specified fair price criteria. For purposes of the above provisions, “resident domestic corporation” means an Indiana corporation that has 100 or more shareholders. “Interested shareholder” means any person, other than the resident domestic corporation or its subsidiaries, who is (1) the beneficial owner, directly or indirectly, of 10% or more of the voting power of the outstanding voting shares of the resident domestic corporation or (2) an affiliate or associate of the resident domestic corporation, which at any time within the five-year period immediately before the date in question, was the beneficial owner, directly or indirectly, of 10% or more of the voting power of the then outstanding shares of the resident domestic corporation.

The definition of “beneficial owner” for purposes of Chapter 43, means a person who individually or with or through any of its affiliates or associates, directly or indirectly, owns or has the right to acquire or vote the subject shares (excluding voting rights under revocable proxies made in accordance with federal law), has any agreement, arrangement or understanding for the purpose of acquiring, holding or voting or disposing of the subject shares, or holds any “derivative instrument” that includes the opportunity to profit or share in any profit derived from any increase in the value of the subject shares.

12

The above provisions do not apply to corporations that elect not to be subject to Chapter 43 in an amendment to their articles of incorporation approved by a majority of the disinterested shareholders. That amendment, however, cannot become effective until 18 months after its passage and would apply only to share acquisitions occurring after its effective date. Our amended articles of incorporation do not exclude us from Chapter 43.

Directors’ Duties and Liability. Under Chapter 35 of the IBCL, directors are required to discharge their duties:

However, the IBCL also provides that a director is not liable for any action taken as a director, or any failure to act, regardless of the nature of the alleged breach of duty (including breaches of the duty of care, the duty of loyalty, and the duty of good faith) unless the director has breached or failed to perform the duties of the director’s office and the action or failure to act constitutes willful misconduct or recklessness.

This exoneration from liability under the IBCL does not affect the liability of directors for violations of the federal securities laws.

Chapter 35 of the IBCL also provides that a board of directors, in discharging its duties, may consider, in its discretion, both the long-term and short-term best interests of the corporation, taking into account, and weighing as the directors deem appropriate, the effects of an action on the corporation’s shareholders, employees, suppliers and customers and the communities in which offices or other facilities of the corporation are located and any other factors the directors consider pertinent. Directors are not required to consider the effects of a proposed corporate action on any particular corporate constituent group or interest as a dominant or controlling factor. If a determination is made with the approval of a majority of the disinterested directors of the board, that determination is conclusively presumed to be valid unless it can be demonstrated that the determination was not made in good faith after reasonable investigation. Chapter 35 specifically provides that specified judicial decisions in Delaware and other jurisdictions, which might otherwise be looked upon for guidance in interpreting Indiana corporate law, including decisions that impose a higher or different degree of scrutiny on actions taken by directors in response to a proposed acquisition of control of the corporation, are inconsistent with the proper application of the business judgment rule under that section.

Mandatory Classified Board of Directors. Under Chapter 33 of the IBCL, a corporation with a class of voting shares registered with the SEC under Section 12 of the Exchange Act must have a classified board of directors unless the corporation adopts a bylaw expressly electing not to be governed by this provision by the later of July 31, 2009 or 30 days after the corporation’s voting shares are registered under Section 12 of the Exchange Act. Although our amended articles of incorporation provide for a classified board of directors (and that provision can only be amended upon the affirmative vote of holders of at least 80% of our outstanding voting stock), we adopted an amendment to our bylaws electing not to be subject to this mandatory requirement effective July 13, 2009; however, the IBCL permits this election to be rescinded by subsequent action of our board of directors.

Certain Effects of Authorized But Unissued Stock

Our authorized but unissued shares of common stock and preferred stock may be issued without additional shareholder approval and may be utilized for a variety of corporate purposes, including future offerings to raise additional capital or to facilitate corporate acquisitions.

13

The issuance of preferred stock could have the effect of delaying or preventing a change in control of our company. The issuance of preferred stock could decrease the amount available for distribution to holders of our common stock or could adversely affect the rights and powers, including voting rights, of such holders. In certain circumstances, such issuance could have the effect of decreasing the market price of our common stock.

One of the effects of the existence of unissued and unreserved common stock or preferred stock may be to enable our board of directors to issue shares to persons friendly to current management, which could render more difficult or discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise, and thereby protect the continuity of management. Such additional shares also could be used to dilute the stock ownership of persons seeking to obtain control of us.

We plan to issue additional shares of common stock in connection with our employee benefit plans.

Transfer Agent and Registrar

EQ Shareowner Services acts as transfer agent and registrar of our common stock.

Listing

Our common stock is listed on the New York Stock Exchange under the symbol “LLY”.

DESCRIPTION OF DEPOSITARY SHARES

The following description of depositary shares does not purport to be complete and is subject to, and qualified in its entirety by, (i) the deposit agreement to be entered into between us and a bank or trust company selected by us and (ii) the depositary receipt relating to the preferred stock that is attached to such deposit agreement. You should read these documents as they, and not this description, define your rights as a holder of depositary shares. Forms of these documents will be deemed filed with the SEC as exhibits to the registration statement of which this prospectus forms a part.

If we elect to offer fractional interests in shares of preferred stock, we will provide for the issuance by a depositary of depositary receipts for depositary shares. Each depositary share will represent fractional interests of preferred stock. We will deposit the shares of preferred stock underlying the depositary shares under the deposit agreement. The bank or trust company must have its principal office in the United States. and a combined capital and surplus of at least $50 million. The depositary receipts will evidence the depositary shares issued under the deposit agreement.

The deposit agreement will contain terms applicable to the holders of depositary shares in addition to the terms stated in the depositary receipts. Each holder of depositary shares will be entitled to all the rights and preferences of the preferred stock underlying the depositary shares in proportion to the applicable fractional interest in the underlying shares of preferred stock. The depositary will issue depositary receipts to individuals purchasing the fractional interests in shares of the related preferred stock according to the terms of the offering described in the applicable prospectus supplement.

Dividends and Other Distributions

The depositary will distribute all cash dividends or other cash distributions received for the preferred stock to the holders of depositary shares in proportion to the number of depositary shares that they own on the relevant record date. The depositary will distribute only an amount that can be distributed without attributing to any holder of depositary shares a fraction of one cent. The depositary will add any undistributed balance to, and treat it as part of, the next sum received by the depositary for distribution to holders of depositary shares.

If there is a non-cash distribution, the depositary will distribute property received by it to the holders of depositary shares in proportion, insofar as possible, to the number of depositary shares owned by them, unless the depositary determines, after consultation with us, that it is not feasible to make such distribution. If this occurs,

14

the depositary may, with our approval, sell such property and distribute the net proceeds from the sale to the holders. The deposit agreement also will contain provisions relating to how any subscription or similar rights that we may offer to holders of the preferred stock will be available to the holders of the depositary shares.

Conversion, Exchange and Redemption

If the preferred stock underlying the depositary shares may be converted or exchanged, each holder of depositary receipts will have the right or obligation, as applicable, to convert or exchange the depositary shares represented by the depositary receipts.

Whenever we redeem shares of preferred stock held by the depositary, the depositary will redeem, at the same time, the number of depositary shares representing the preferred stock. The depositary will redeem the depositary shares from the proceeds it receives from the corresponding redemption, in whole or in part, of the underlying preferred stock. The depositary will send notice of redemption to the holders of the depositary shares that are to be redeemed between 30 and 60 days before the date fixed for redemption. The redemption price per depositary share will be equal to the applicable fraction of the redemption price per share on the underlying preferred stock. If less than all the depositary shares are to be redeemed, the depositary will select which shares to be redeemed by lot, proportionate allocation or any other method.

After the date fixed for redemption, the depositary shares called for redemption will no longer be outstanding. When the depositary shares are no longer outstanding, all rights of the holders will end, except the right to receive money, securities or other property payable upon redemption.

Voting

When the depositary receives notice of a meeting at which the holders of the preferred stock are entitled to vote, the depositary will send the particulars of the meeting to the holders of the depositary shares. Each holder of depositary shares on the record date may instruct the depositary on how to vote the shares of preferred stock underlying the holder’s depositary shares. The depositary will try, if practical, to vote the number of shares of preferred stock underlying the depositary shares according to the instructions. The depositary will abstain from voting shares of the preferred stock to the extent it does not receive specific instructions from the holders of depositary shares representing such preferred stock. We will agree to take all reasonable action requested by the depositary to enable it to vote as instructed.

Record Date

Whenever (1) any cash dividend or other cash distribution shall become payable, any distribution other than cash shall be made, or any rights, preferences or privileges shall be offered with respect to the underlying preferred stock, or (2) the depositary shall receive notice of any meeting at which holders of the underlying preferred stock are entitled to vote or of which holders of the underlying preferred stock are entitled to notice, or of the mandatory conversion of or any election on our part to call for the redemption of any of the underlying preferred stock, the depositary shall in each such instance fix a record date (which shall be the same as the record date for the underlying preferred stock) for the determination of the holders (x) who shall be entitled to receive such dividend, distribution, rights, preferences or privileges or the net proceeds of the sale thereof or (y) who shall be entitled to give instructions for the exercise of voting rights at any such meeting or to receive notice of such meeting or of such redemption or conversion, subject to the provisions of the deposit agreement.

Amendments

We and the depositary may agree to amend the deposit agreement and the depositary receipt evidencing the depositary shares. Any amendment that (a) imposes or increases certain fees, taxes or other charges payable by the holders of the depositary shares as described in the deposit agreement or (b) otherwise prejudices any substantial existing right of holders of depositary shares, will not take effect until 30 days after the depositary has sent notice of the amendment to the record holders of depositary shares. Any holder of depositary shares that continues to hold its shares at the end of the 30-day period will be deemed to have agreed to the amendment.

15

Termination

We may, at our option, direct the depositary to terminate the deposit agreement by sending a notice of termination to holders of depositary shares at least 30 days prior to termination. In addition, a deposit agreement will automatically terminate if:

The depositary may likewise terminate the deposit agreement if at any time 60 days shall have expired after the depositary shall have delivered to us a written notice of its election to resign and a successor depositary shall not have been appointed and accepted its appointment. If any depositary receipts remain outstanding after the date of termination, the depositary thereafter will discontinue the transfer of depositary receipts, will suspend the distribution of dividends to the holders thereof, and will not give any further notices (other than notice of such termination) or perform any further acts under the deposit agreement except that the depositary will continue (1) to collect dividends on the underlying preferred stock and any other distributions with respect thereto and (2) to deliver the underlying preferred stock together with such dividends and distributions and the net proceeds of any sales of rights, preferences, privileges or other property, without liability for interest thereon, in exchange for depositary receipts surrendered. At any time after the expiration of two years from the date of termination, the depositary may sell any underlying preferred stock then held by it at public or private sales, at such place or places and upon such terms as it deems proper and may thereafter hold the net proceeds of any such sale, together with any money and other property then held by it, without liability for interest thereon, for the pro rata benefit of the holders of depositary receipts which have not been surrendered.

We will pay all fees, charges and expenses of the depositary, including the initial deposit of the preferred stock and any redemption of the preferred stock. Holders of depositary shares will pay transfer and other taxes and governmental charges and any other charges as are stated in the deposit agreement for their accounts.

The deposit agreement limits our obligations and the depositary’s obligations to performance in good faith of the duties stated in the deposit agreement. The depositary will not be obligated to prosecute or defend any legal proceeding connected with any depositary shares or preferred stock unless the holders of depositary shares requesting the depositary to do so furnish it with satisfactory indemnity. In performing our obligations, we and the depositary may rely upon the written advice of our counsel or accountants, on any information that competent people provide to us and on documents that we believe are genuine.

DESCRIPTION OF DEBT SECURITIES

We may offer and issue our debt securities from time to time in one or more series. The debt securities are to be issued under an indenture, dated as of February 1, 1991, between us and Deutsche Bank Trust Company Americas (as successor to Citibank, N.A.), as trustee. The indenture does not limit the aggregate principal amount of the debt securities that may be issued thereunder. The indenture, which incorporates our standard multiple-series indenture provisions as Annex A thereto, is an exhibit to the registration statement of which this prospectus is a part. The following information summarizes certain general terms of the debt securities as described in the indenture. The indenture is subject to and governed by the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act.

We will summarize in the applicable prospectus supplement certain specific terms of the debt securities, any modifications of or additions to the general terms of the debt securities described herein and any applicable material federal income tax considerations. Accordingly, please read both this prospectus and the applicable prospectus supplement for a summary of the terms of the debt securities of any particular series. Any such summary does not purport to be complete and is subject to, and is qualified in its entirety by reference to, the actual provisions of the indenture and the debt securities.

For purposes of this summary, the terms the “company,” “we,” “our” and “us” refer only to Eli Lilly and Company and not to any of its subsidiaries, unless we specify otherwise.

General

The debt securities will be our unsecured general obligations. The indebtedness represented by the debt securities will rank equally with all other unsecured and unsubordinated indebtedness of our company. The debt securities may be issued in one or more series, and unless otherwise provided, a series may be reopened for the issuance of additional debt securities of such series. Also, a single series may be issued at various times with different maturity dates, different interest rates and different dates from which interest accrues. One or more series of debt securities may be issued with the same or various maturities at par or at a discount. Debt securities bearing no interest or interest at a rate which at the time of issuance is below the market rate (“original issue discount securities”) will be sold at a discount below their stated principal amount. This discount may be substantial. We will provide information regarding material federal income tax consequences and other special considerations applicable to any original issue discount securities in the applicable prospectus supplement.

If we denominate the purchase price of any of the debt securities in a foreign currency or currencies, or if the principal of or premium, if any, or interest on any series of debt securities is payable in a foreign currency or currencies, we will include in the applicable prospectus supplement information on the restrictions, elections, material federal income tax considerations, specific terms and other information with respect to that issue of debt securities and the foreign currency or currencies.

A prospectus supplement relating to a series of debt securities will include certain specific terms, including some or all of the following:

17

18

We may authorize the issuance and provide for the terms of a series of debt securities pursuant to a resolution of our board of directors or any duly authorized committee of our board of directors or pursuant to a supplemental indenture.

We may issue the debt securities as registered securities, bearer securities or both. We may issue the debt securities in whole or in part in the form of one or more global securities. One or more global securities will be issued in a denomination or aggregate denominations equal to the aggregate principal amount of outstanding debt securities of the series to be represented by such global security or global securities.

If we issue bearer securities, we will describe the limitations on the issuance of the bearer securities as well as certain material federal income tax consequences and other special considerations applicable to bearer securities in an applicable prospectus supplement.

Exchange, Registration and Transfer

A holder of debt securities in bearer form may, upon written request in accordance with the terms of the indenture, exchange the bearer securities for (1) registered securities (with all unmatured coupons, except as provided below) of the same series, with the same interest rate and maturity date (if the debt securities of such series are to be issued as registered securities) or (2) bearer securities (if bearer securities of such series are to be issued in more than one denomination) of the same series with the same interest rate and maturity date. However, no bearer security will be delivered in or to the United States, and registered securities of any series (other than a global security, except as set forth below) will be exchangeable into an equal aggregate principal amount of registered securities of the same series (with the same interest rate and maturity date) of different authorized denominations. If a holder surrenders bearer securities between a record date and the relevant interest payment date, such holder will not be required to surrender the coupon relating to such interest payment date. Registered securities may not be exchanged for bearer securities.

Bearer or registered securities may be presented for exchange, and registered securities, other than a global security, may be presented for transfer, at the office of any transfer agent or at the office of the security registrar, without service charge and upon payment of any taxes and other governmental charges as provided in the indenture. The transfer or exchange will be completed upon the transfer agent or the security registrar’s satisfaction with the documents of title and identity of the person making the request. Bearer securities, and the coupons, if any, relating to the bearer securities, shall be transferred by delivery of the bearer securities.

Global Securities

We may issue debt securities of a series in whole or in part in the form of one or more global securities. The global securities will be deposited with, or on behalf of, the depositary named in the applicable prospectus supplement. Global securities may be issued in either registered or bearer form and in either temporary or permanent form. Unless and until the global security is exchanged in whole or in part for debt securities in definitive registered form, a global security may not be transferred except as a whole by the depositary (or its nominee) for such global security. If transferred in whole, the following are types of transfers which are allowed for global securities:

19

The specific terms of the depositary arrangement with respect to any debt securities of a series will be described in the applicable prospectus supplement. We anticipate that the following provisions will apply to all depositary arrangements.

Upon the issuance of a global security, the depositary for such global security will credit, on its book-entry registration and transfer system, the respective principal amounts of the debt securities represented by the global security to the accounts of participant institutions that have accounts with the depositary. We or the underwriters, if the debt securities were sold by underwriters, shall designate the accounts to be credited. We will limit ownership of beneficial interests in a global security to participants or persons that may hold interests through participants. Ownership of beneficial interests in the global security will be shown on records maintained by the depositary. The transfer of the ownership of the global security will be effected only through the records maintained by the depositary. The laws of some states require that certain purchasers of debt securities take physical delivery of such debt securities in definitive form. These laws may impair your ability to transfer beneficial interests in a global security.

So long as the depositary for a global security, or its nominee, is the owner of the global security, that depositary or nominee will be considered the sole owner or holder of the debt securities represented by such global security for all purposes under the indenture. Except as set forth below, owners of beneficial interests in a global security (1) will not be entitled to have debt securities of the series represented by the global security registered in their names, (2) will not receive or be entitled to receive physical delivery of debt securities of the series in definitive form, and (3) will not be considered the owners or holders thereof under the indenture governing the debt securities.

Subject to certain limitations on the issuance of bearer securities which will be described in the applicable prospectus supplement, payments of principal of, premium, if any, and interest, if any, on debt securities registered in the name of or held by a depositary or its nominee will be made to the depositary or its nominee, as the registered owner or the holder of the global security representing those debt securities. None of the company, the applicable trustee, any paying agent or the applicable security registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a global security for the debt securities or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

We expect that the depositary for debt securities of a series, upon receipt of any payment of principal, premium, if any, or interest, if any, in respect of a permanent global security, will credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the global security as shown on the records of the depositary. We also expect that payments by participants to owners of beneficial interests in the global security held through the participants will be governed by standing instructions and customary practices, as is now the case with debt securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of those participants. There may be restrictions on receipt by owners of beneficial interests in a temporary global security of payments in respect of such temporary global security. We will describe any such restrictions in the applicable prospectus supplement.

If a depositary for debt securities of a series is at any time unwilling or unable to continue as depositary, or is ineligible to act as depositary, and we do not appoint a successor depositary within 90 days, we will issue debt securities of that series in definitive form in exchange for the global security or securities representing the debt securities of that series. In addition, we may at any time and in our sole discretion determine not to have any debt securities of a series represented by one or more global securities. If we decide not to have any debt securities of a series represented by a global security, we will issue debt securities of that series in definitive form in exchange for the global security or securities representing such debt securities. Further, if we so provide with respect to the

20

debt securities of a series, each person specified by the depositary of the global security representing debt securities of such series may, on terms acceptable to us and the depositary for such global security, receive debt securities of such series in definitive form. In any such instance, each person so specified by the depositary of the global security will be entitled to physical delivery in definitive form of debt securities of the series represented by the global security equal in principal amount to the person’s beneficial interest in the global security. Debt securities of that series so issued in definitive form will be issued (1) as registered securities if the debt securities of that series are to be issued as registered securities, (2) as bearer securities if the debt securities of that series are to be issued as bearer securities or (3) as either registered securities or bearer securities, if the debt securities of that series are to be issued in either form. A description of certain restrictions on the issuance of a bearer security in definitive form in exchange for an interest in a global security will, if applicable, be contained in the applicable prospectus supplement.

Payment and Paying Agents

Bearer Securities

We will pay the principal, interest, if any, and premium, if any, on bearer securities in the currency or currency unit designated in the prospectus supplement, subject to any applicable laws and regulations, at such paying agencies outside the United States as we may appoint from time to time. At the option of a holder, we will make such payment by a check in the designated currency or currency unit or by transfer to an account in the designated currency or currency unit maintained by the payee with a bank located outside the United States. We will make no payment with respect to any bearer security:

However, we may pay principal, interest, if any, and premium, if any, on bearer securities in U.S. dollars at the principal corporate trust office of the trustee in the Borough of Manhattan, The City of New York, if payment of the full amount thereof at all paying agencies outside the United States is illegal or effectively precluded by exchange controls or other similar restrictions.

Registered Securities

Unless otherwise set forth in the applicable prospectus supplement,

We will name in the prospectus supplement the paying agents, if any, outside the United States initially appointed by us for a series of debt securities. We may terminate the appointment of any of the paying agents from time to time, except that we will maintain at least one paying agent in the Borough of Manhattan, The City of New York, for payments with respect to registered securities. We will also maintain at least one paying agent in a city in Europe so long as any bearer securities are outstanding where bearer securities may be presented for payment and may be surrendered for exchange. However, so long as any series of debt securities is listed on any stock exchange located outside the United States and such stock exchange shall so require, we will maintain a paying agent in any required city located outside the United States, for those series of debt securities.

21

All moneys we pay to the trustee or a paying agent for the payment of principal of or premium, if any, or interest, if any, on any debt security that remain unclaimed at the end of two years after such principal, premium or interest shall have become due and payable will be repaid to us, and the holder of such debt security entitled to receive such payment will thereafter look only to us for payment thereof.

Concerning the Trustee

Deutsche Bank Trust Company Americas is the current trustee under the indenture. The trustee shall, prior to the occurrence of any event of default with respect to the debt securities of any series and after the curing or waiving of all events of default with respect to such series which have occurred, perform only such duties as are specifically set forth in such indenture. During the existence of any event of default with respect to the debt securities of any series, the trustee shall exercise such of the rights and powers vested in it under the indenture with respect to such series and use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs.

The trustee may acquire and hold debt securities and, subject to certain conditions, otherwise deal with us as if it were not trustee under the indenture.

The trustee and its affiliates have in the past provided, and may from time to time in the future provide, trustee, commercial banking, investment banking and other services to us in the ordinary course of their respective businesses for which they have received, and will receive, customary compensation.

Modification of the Indenture

The indenture contains provisions permitting us and the trustee, without the consent of the holders of the debt securities, to establish, among other things, the form and terms of any series of debt securities issuable under the indenture by one or more supplemental indentures, to add covenants and to provide for security for the debt securities.

With the consent of the holders of not less than a majority of the aggregate principal amount of the debt securities of any series at the time outstanding, we and the trustee may execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the indenture or of any supplemental indenture with respect to the debt securities of such series or modifying in any manner the rights of the holders of the debt securities of such series. However, without the consent of the holders of each debt security so affected, we and the trustee may not (1) extend the fixed maturity, or the earlier optional date of maturity, if any, of any debt security of such series, (2) reduce the principal amount of any debt security of such series, (3) reduce the premium of any debt security of such series, if any, (4) reduce the rate or extend the time of payment of interest, if any, of any debt security of such series, or (5) make the principal thereof or premium, if any, or interest, if any, of any debt security of such series payable in any currency other than as provided therein or pursuant to the indenture. Also, without the consent of the holders of all debt securities of such series outstanding thereunder, we and the trustee may not reduce the percentage of debt securities of such series, the holders of which are required to consent to any such supplemental indenture.

Certain Covenants of Debt Securities

The indenture contains, among other things, the following covenants:

Limitation on Liens. We will not, and will not permit any of our subsidiaries to, create, assume or suffer to exist any lien on restricted property to secure any of our debt, any debt of any of our subsidiaries or any debt of any other person unless we also secure the debt securities of any series having the benefit of this covenant by a lien equally and ratably with such other debt for so long as such other debt shall be so secured. The indenture contains the following exceptions to the foregoing prohibition:

22

Limitation on Sale and Leaseback Transactions. We will not, and will not permit any of our subsidiaries owning restricted property to, enter into any sale and leaseback transaction unless:

Definitions of Certain Terms

The following are the meanings of terms that are important in understanding the covenants previously described:

23

Because the covenants described above cover only manufacturing facilities in the continental United States, our manufacturing facilities in Puerto Rico and elsewhere in the world are excluded from the operation of the covenants described above.

Except as described in “Merger or Consolidation” below, there are no other restrictive covenants contained in the indenture. The indenture does not contain any provision which restricts us from incurring, assuming or becoming liable with respect to any indebtedness or other obligations, whether secured or unsecured, or from paying dividends or making other distributions on our capital stock or purchasing or redeeming our capital stock. The indenture does not contain any financial ratios, or specified levels of net worth or liquidity to which we must adhere. In addition, the indenture does not contain any provision which would require that we repurchase or redeem or otherwise modify the terms of any of our debt securities upon a change in control or other events involving us which may adversely affect the creditworthiness of the debt securities.

24

Events of Default

The indenture provides that, with respect to any series of debt securities, an event of default consists of:

The indenture provides that if an event of default with respect to any series of debt securities at the time outstanding occurs and is continuing, either the trustee or the holders of 25% or more in aggregate principal amount (or, if the debt securities of that series are original issue discount securities, such portion of the principal amount as may be specified in the terms of that series) of debt securities of such series outstanding may declare the principal amount of all debt securities of such series to be due and payable immediately. At any time after a declaration of acceleration with respect to the debt securities of any series has been made and before there has been a sale of property under a judgment or decree for the payment of moneys due, the holders of a majority in aggregate principal amount of the debt securities of such series outstanding may waive the default and rescind the declaration and its consequences if:

The indenture provides that the holders of a majority in aggregate principal amount of the debt securities of any series outstanding under the indenture may, subject to certain exceptions, direct the trustee as to the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any power or trust conferred upon the trustee. The holders of a majority in aggregate principal amount of the debt securities of any series outstanding may on behalf of all holders of debt securities of such series waive any past default and its consequences with respect to debt securities of such series, except a default in the payment of the principal of, premium, if any, or interest, if any, on any of the debt securities of such series.

25

Holders of any debt securities of any series may not institute any proceeding to enforce the indenture or any remedy thereunder unless the trustee shall have failed to act for 60 days after a request and offer of reasonable indemnity by the holders of 25% or more in aggregate principal amount of the debt securities of such series outstanding. However, the right of any holder of any security of any series to enforce payment of the principal of or premium, if any, or interest, if any, on its debt securities when due shall not be impaired without the consent of such holder.

The trustee is required to give the holders of any debt security of any series notice of default with respect to such series known to it within 90 days after the happening of the default, unless cured before the giving of such notice. However, except for defaults in payments of the principal of or premium, if any, or interest, if any, on the debt securities of such series, the trustee may withhold notice if and so long as it determines in good faith that the withholding of such notice is in the interests of the holders of the debt securities of such series.

We are required to deliver to the trustee each year an officers’ certificate stating whether such officers have obtained knowledge of any default by our company in the performance of all covenants and, if so, specifying the nature of such default.

Merger or Consolidation

The indenture provides that without the consent of the holders of any of the outstanding debt securities under the indenture, we may consolidate with or merge into, or transfer or lease substantially all of our assets to, any domestic corporation, association, company or business trust (as used in this subsection, a “corporation”), provided:

Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. As a result of this uncertainty:

Discharge, Legal Defeasance and Covenant Defeasance

We may discharge certain obligations to holders of any series of debt securities that have not already been delivered to the trustee for cancellation and that either have become due and payable or will become due and payable within one year (or are to be called for redemption within one year under arrangements satisfactory to the trustee for the giving of notice) by irrevocably depositing with the trustee, in trust, funds in the currency or currencies in which those debt securities are payable in an amount sufficient to pay the entire indebtedness on those debt securities in respect of principal, premium, if any, and interest, if any, to the date of that deposit (if those debt securities have become due and payable) or to the maturity date, as the case may be.

26

At our option, we may be discharged, subject to certain terms and conditions, from any and all obligations in respect of the debt securities of any series (except for certain obligations to register the transfer and exchange of debt securities, replace, stolen, lost or mutilated debt securities and coupons, maintain paying agencies and hold moneys for payment in trust) or need not comply with certain restrictive covenants of the indenture if:

(1) we have deposited with the trustee, in trust, money, and in the case of debt securities and coupons denominated in U.S. dollars, U.S. government obligations or, in the case of debt securities and coupons denominated in a foreign currency, foreign currency government securities, which through the payment of interest thereon and principal thereof in accordance with their terms will provide money or a combination of money, and either U.S. government securities or foreign currency government securities, as the case may be, in an amount sufficient to pay in the currency in which the debt securities are payable all the principal of and premium, if any, and interest, if any, on the debt securities on the date such payments are due in accordance with the debt securities;

(2) (i) no event of default or event which with notice or lapse of time would become an event of default shall have occurred and be continuing on the date of such deposit, (ii) no event of default relating to our bankruptcy, insolvency or reorganization, or event which with notice or lapse of time or both would become such an event of default, shall have occurred within 90 days after the date of such deposit, and (iii) such deposit and discharge will not result in any default or event of default under any material indenture, agreement or other instrument binding upon us or any of our properties;

(3) we have delivered to the trustee an opinion of counsel to the effect that such deposit and discharge will not cause the holders of the debt securities of such series to recognize income, gain or loss for federal income tax purposes and that such holders will be subject to federal income tax in the same amounts, manner and time had such deposit and discharge not occurred; and

(4) we have delivered to the trustee an officers’ certificate and an opinion from our counsel stating that we have complied with all conditions precedent set forth in the indenture or the applicable supplemental indenture relating to the satisfaction and discharge of the indebtedness of the series of debt securities.

Governing Law

The indenture and the debt securities for all purposes will be governed by and construed in accordance with the laws of the State of New York.

DESCRIPTION OF WARRANTS

We may issue debt warrants for the purchase of debt securities or stock warrants for the purchase of preferred stock or common stock.

The warrants will be issued under warrant agreements to be entered into between us and a bank or trust company, as warrant agent, all to be set forth in the applicable prospectus supplement relating to any or all warrants in respect of which this prospectus is being delivered. Copies of the form of agreement for each warrant, including the forms of certificates representing the warrants reflecting the provisions to be included in such agreements that will be entered into with respect to the particular offerings of each type of warrant, will be filed as exhibits to the registration statement of which this prospectus forms a part.

The following description sets forth certain general terms and provisions of the warrants to which any prospectus supplement may relate. The particular terms of the warrants to which any prospectus supplement may relate and the extent, if any, to which such general provisions may apply to the warrants so offered will be

27

described in the applicable prospectus supplement. The following summary of certain provisions of the warrants, warrant agreements and warrant certificates does not purport to be complete and is subject to, and is qualified in its entirety by reference to, all the provisions of the warrant agreements and warrant certificates, including the definitions therein of certain terms.

Debt Warrants

General. Reference is made to the applicable prospectus supplement for the terms of debt warrants in respect of which this prospectus is being delivered, the debt securities warrant agreement relating to such debt warrants and the debt warrant certificates representing such debt warrants, including the following:

The debt warrant certificates will be exchangeable for new debt warrant certificates of different denominations and debt warrants may be exercised at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement. Prior to the exercise of their debt warrants, holders of debt warrants will not have any of the rights of holders of the debt securities purchasable upon such exercise and will not be entitled to any payments of principal and premium, if any, and interest, if any, on the debt securities purchasable upon such exercise.

Exercise of Debt Warrants. Each debt warrant will entitle the holder to purchase for cash such principal amount of debt securities at such exercise price as shall in each case be set forth in, or be determinable as set forth in, the applicable prospectus supplement relating to the debt warrants offered thereby. Unless otherwise specified in the applicable prospectus supplement, debt warrants may be exercised at any time up to 5:00 p.m., New York City time, on the expiration date set forth in the applicable prospectus supplement. After 5:00 p.m., New York City time, on the expiration date, unexercised debt warrants will become void.

Upon receipt of payment and the debt warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement, we will, as soon as practicable, forward the debt securities purchasable upon such exercise. If less than all of the debt warrants represented by such debt warrant certificate are exercised, a new debt warrant certificate will be issued for the remaining amount of debt warrants.

Stock Warrants

General. Reference is made to the applicable prospectus supplement for the terms of stock warrants in respect of which this prospectus is being delivered, the stock warrant agreement relating to such stock warrants and the stock warrant certificates representing such stock warrants, including the following:

The stock warrant certificates will be exchangeable for new stock warrant certificates of different denominations and stock warrants may be exercised at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement. Prior to the exercise of their stock warrants, holders of stock warrants will not have any of the rights of holders of shares of capital stock purchasable upon such exercise and will not be entitled to any dividend or other distribution payments on such capital stock purchasable upon such exercise.

Exercise of Stock Warrants. Each stock warrant will entitle the holder to purchase for cash such number of shares of preferred stock or common stock, as the case may be, at such exercise price as shall in each case be set forth in, or be determinable as set forth in, the applicable prospectus supplement relating to the stock warrants offered thereby. Unless otherwise specified in the applicable prospectus supplement, stock warrants may be exercised at any time up to 5:00 p.m., New York City time, on the expiration date set forth in the applicable prospectus supplement.

Stock warrants may be exercised as set forth in the applicable prospectus supplement relating thereto. Upon receipt of payment and the stock warrant certificates properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement, we will, as soon

29

as practicable, forward a certificate representing the number of shares of capital stock purchasable upon such exercise. If less than all of the stock warrants represented by such stock warrant certificate are exercised, a new stock warrant certificate will be issued for the remaining amount of stock warrants.

DESCRIPTION OF STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS

We may issue stock purchase contracts, representing contracts obligating holders to purchase from us, and requiring us to sell to the holders, a specified number of shares of common stock at a future date or dates. The price per share of common stock may be fixed at the time the stock purchase contracts are issued or may be determined by reference to a specific formula set forth in the stock purchase contracts. The stock purchase contracts may be issued separately or as a part of units, or stock purchase units, consisting of a stock purchase contract and either (x) senior debt securities, senior subordinated debt securities, subordinated debt securities or junior subordinated debt securities, or (y) debt obligations of third parties, including U.S. Treasury securities, in each case, securing the holder’s obligations to purchase the common stock under the stock purchase contracts. The stock purchase contracts may require us to make periodic payments to the holders of the stock purchase contracts or vice versa, and such payments may be unsecured or prefunded on some basis. The stock purchase contracts may require holders to secure their obligations thereunder in a specified manner and in certain circumstances we may deliver newly issued prepaid stock purchase contracts, or prepaid securities, upon release to a holder of any collateral securing such holder’s obligations under the original stock purchase contract.

The applicable prospectus supplement will describe the terms of any stock purchase contracts or stock purchase units and, if applicable, prepaid securities. The description in the prospectus supplement will not purport to be complete and will be qualified in its entirety by reference to the stock purchase contracts, the collateral arrangements and depositary arrangements, if applicable, relating to such stock purchase contracts or stock purchase units and, if applicable, the prepaid securities and the document pursuant to which such prepaid securities will be issued.

PLAN OF DISTRIBUTION

We may sell the offered securities in five ways: (1) to or through underwriters; (2) to or through dealers; (3) through agents; (4) directly or through our subsidiaries to purchasers; and (5) through a combination of the foregoing methods.

We may distribute the offered securities from time to time in one or more transactions at (1) a fixed price or prices, which may be changed, (2) at market prices prevailing at the time of sale, (3) at prices related to such market prices, or (4) at negotiated prices.

If underwriters are used in the offering of the offered securities, the names of the managing underwriter or underwriters and any other underwriters and certain terms of the offering, including compensation of the underwriters and dealers, if any, will be set forth in the applicable prospectus supplement. Only underwriters named in the applicable prospectus supplement will be deemed to be underwriters in connection with the offered securities described in that prospectus supplement. Firms not so named will have no direct or indirect participation in the underwriting of such securities, although such a firm may participate in the distribution of those securities under circumstances entitling that firm to a dealer’s commission. It is anticipated that any underwriting agreement pertaining to any offered securities will (i) entitle the underwriters to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution for payments which the underwriters may be required to make in respect thereof, (ii) provide that the obligations of the underwriters will be subject to certain conditions precedent and (iii) provide that the underwriters generally will be obligated to purchase all of the offered securities if any are purchased.

We also may sell the offered securities to a dealer as principal. If we sell the offered securities to a dealer as a principal, then the dealer may resell those securities to the public at varying prices to be determined by such dealer at the time of resale. The name of the dealer and the terms of the transactions will be set forth in the applicable prospectus supplement.

The offered securities also may be offered through agents we may designate from time to time. The applicable prospectus supplement will contain the name of any such agent and the terms of its agency. Unless otherwise indicated in the prospectus supplement, any such agent will act on a best efforts basis for the period of its appointment.

As one of the means of direct issuance of the offered securities, we may utilize the services of any available electronic auction system to conduct an electronic “dutch auction” of the offered securities among potential purchasers who are eligible to participate in the auction of such securities, if so described in the prospectus supplement.

Dealers and agents named in a prospectus supplement may be deemed to be underwriters (within the meaning of the Securities Act) of the securities described in the prospectus supplement and, under agreements which may be entered into with us, may be entitled to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution for payments which they may be required to make in respect of those liabilities.

Underwriters, dealers and agents may engage in transactions with us, or perform services for us in the ordinary course of business.

Offers to purchase the offered securities may be solicited directly by us or through our subsidiaries and sales thereof may be made by us directly to institutional investors or others. The terms of any such sales will be described in the applicable prospectus supplement.
