Ladies and Gentlemen:

Eli Lilly and Company, an Indiana corporation (the “Company”), proposes to issue and sell to the several Underwriters listed in Schedule 1 hereto (the “Underwriters”), for whom you are acting as representatives (the “Representatives”), $850,000,000 in aggregate principal amount of its 2.500% Notes due 2060 (the “2060 Notes”) and $250,000,000 in aggregate principal amount of its 2.250% Notes due 2050 (the “New 2050 Notes” and, together with the 2060 Notes, the “Securities”), in each case on the terms set forth in Schedule 2 hereto. The Securities will be issued pursuant to an Indenture, dated as of February 1, 1991 (as may be supplemented from time to time, the “Indenture”), between the Company and Deutsche Bank Trust Company Americas, a New York banking corporation (as successor to Citibank, N.A., the original trustee), as trustee (the “Trustee”).

On May 5, 2020, the Company issued $1,000,000,000 in aggregate principal amount of its 2.250% Notes due 2050 under the Indenture (the “Existing Securities”). The New 2050 Notes will constitute an issuance of additional Securities (as such term is used in the Indenture) under the Indenture. Except as otherwise described in the Prospectus, the New 2050 Notes will have the same terms (other than the issue date and initial offering price) to the Existing Securities and will be treated together with the Existing Securities as a single series of Securities (as such term is defined in the Indenture) for all purposes under the Indenture.

The Company agrees to issue and sell the Securities to the several Underwriters as provided in this Underwriting Agreement (this “Agreement”), and each Underwriter, on the basis of the accuracy of the representations and warranties as of the Time of Sale and as of the Closing Date (as defined below) and the agreements set forth herein and incorporated by reference herein, and subject to the conditions set forth herein and incorporated by reference herein, agrees, severally and not jointly, to purchase from the Company the respective principal amount of Securities set forth opposite such Underwriter’s name in Schedule 1 hereto at a price equal to (i) 97.207% of the principal amount of the 2060 Notes plus accrued interest, if any, from August 25, 2020 to the Closing Date, and (ii) 98.027% of the principal amount of the New 2050 Notes plus accrued interest from May 5, 2020 to the Closing Date. The Company will not be obligated to deliver any of the Securities except upon payment for all the Securities to be purchased as provided herein.

The Company understands that the Underwriters intend to make a public offering of the Securities as soon after the effectiveness of this Agreement as in the judgment of the Representatives is advisable, and initially to offer the Securities on the terms set forth in the Time of Sale Information and the Prospectus. Schedule 3 hereto sets forth the Time of Sale Information made available at the Time of Sale. The Company acknowledges and agrees that the Underwriters may offer and sell Securities to or through any affiliate of an Underwriter and that any such affiliate may offer and sell Securities purchased by it to or through any Underwriter.

In the event that any Underwriter that is a (i) “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b), (ii) a “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b), or (iii) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b) (each, a “Covered Entity”) becomes subject to a proceeding under (a) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (b) Title II of the Dodd-Frank Wall

Street Reform and Consumer Protection Act and the regulations promulgated thereunder (each, a “U.S. Special Resolution Regime”), the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate (as defined by the meaning assigned to the term “affiliate” in, and interpreted in accordance with, 12 U.S.C. § 1841(k)) of such Underwriter becomes subject to a proceeding under the U.S. Special Resolution Regime, Default Rights (as that term is defined in, and interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable) under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

Payment for and delivery of the Securities shall be made through the offices of Davis Polk & Wardwell LLP, 450 Lexington Avenue, New York, New York 10017 at 10:00 A.M., New York City time, on August 25, 2020, or at such other time or place on the same or such other date, not later than the seventh business day thereafter, as the Representatives and the Company may agree upon in writing (the “Closing Date”).

Payment for the Securities shall be made by wire transfer in immediately available funds to the account(s) specified by the Company to the Representatives against delivery to the nominee of The Depository Trust Company, for the account of the Underwriters, of one or more global notes representing each of the Securities (collectively, the “Global Note”), with any transfer taxes payable in connection with the sale of the Securities duly paid by the Company. The Global Note (or a true copy thereof) will be made available for inspection by the Representatives not later than 1:00 P.M., New York City time, on the business day prior to the Closing Date.

All provisions contained in the document entitled Eli Lilly and Company Underwriting Agreement Standard Provisions (Debt Securities), dated February 20, 2014 (the “Standard Provisions”), are incorporated by reference herein in their entirety and shall be deemed to be a part of this Agreement to the same extent as if such provisions had been set forth in full herein, except that if any term defined in such Standard Provisions is otherwise defined herein, the definition set forth herein shall control.

This Agreement may be signed in counterparts (which may include counterparts delivered by any standard form of telecommunication), each of which shall be an original and all of which together shall constitute one and the same instrument.

All statements, requests, notices and agreements shall be in writing (including transmissions by electronic mail or facsimile) and, if to the Underwriters, shall be sufficient in all respects if delivered or sent to the Representatives at the offices or facsimile numbers thereof specified in Schedule 2 hereto, as may be amended from time to time by written notice to the Company; and if to the Company, shall be sufficient in all respects if delivered or sent to the Company at the offices of the Company at Lilly Corporate Center, Indianapolis, Indiana 46285, email: paz_robert_l@lilly.com and Lilly_DCM@lists.lilly.com, Attention: Treasury team.

STANDARD PROVISIONS

(DEBT SECURITIES)

February 20, 2014

From time to time, Eli Lilly and Company, an Indiana corporation (the “Company”), may enter into one or more underwriting agreements in the form of Annex A hereto that provide for the sale of designated securities (the “Offered Securities”) to the several underwriters named therein (each an “Underwriter” and collectively, the “Underwriters”) for whom certain Underwriter(s) named therein shall act as representative(s) (the “Representative(s)”). The standard provisions set forth herein may be incorporated by reference in any such underwriting agreement (an “Underwriting Agreement”). The Underwriting Agreement, including the provisions incorporated therein by reference, is herein referred to as this Agreement. Terms defined in the Underwriting Agreement are used herein as therein defined.

The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), a registration statement on Form S–3 relating to, inter alia, the debt securities to be issued from time to time by the Company. The Company has also filed, or proposes to file, with the Commission pursuant to Rule 424 under the Securities Act a prospectus generally relating to the debt securities (the “Basic Prospectus”) and a prospectus supplement specifically relating to the Offered Securities (the “Prospectus Supplement”). The registration statement, as amended at the time it becomes effective, including the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement”; and as used herein, the term “Prospectus” means the Basic Prospectus as supplemented by the prospectus supplement specifically relating to the Offered Securities in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with confirmation of sales of the Offered Securities and the term “Preliminary Prospectus” means the preliminary prospectus supplement specifically relating to the Offered Securities together with the Basic Prospectus. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement and the Prospectus. References herein to the Registration Statement, the Basic Prospectus, the Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein. The terms “supplement,” “amendment” and “amend” as used herein with respect to the Registration

1

Statement, any Preliminary Prospectus or the Prospectus shall be deemed to include any documents filed by the Company under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (the “Exchange Act”) subsequent to the date of the Underwriting Agreement which are deemed to be incorporated by reference therein. For purposes of this Agreement, the term “Effective Time” means the effective date of the Registration Statement with respect to the offering of the Offered Securities, as determined for the Company pursuant to Section 11 of the Securities Act and Item 512 of Regulation S-K, as applicable.

At or prior to the time when sales of the Offered Securities will be first made (the “Time of Sale”), the Company will prepare certain information (collectively, the “Time of Sale Information”) which information will be identified in Schedule 3 to the Underwriting Agreement, or such other schedule as specified therein, for such offering as constituting part of the Time of Sale Information.

No order suspending the effectiveness of the Registration Statement has been issued by the Commission and no proceeding for that purpose or pursuant to Section 8A of the Securities Act against the Company or related to the offering has been initiated or, to the best of the knowledge of the Company, threatened by the Commission; as of the Effective Time, the Registration Statement complied in all material respects with the Securities Act and the Trust Indenture Act of 1939, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Trust Indenture Act”), and did not or will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading; and as of the date of the Prospectus Supplement and any amendment or supplement thereto and as of the Closing Date, the Prospectus did not and will not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that the Company makes no representation and warranty with respect to (i) that part of the Registration Statement that constitutes the Statement of Eligibility (Form T-1) of the Trustee under the Trust Indenture Act or (ii) any statements or omissions in the Registration

(u) The Company is not an “ineligible issuer” and is a “well-known seasoned issuer,” in each case as defined under the Securities Act, in each case at the times specified in the Securities Act in connection with the offering of the Offered Securities.

The Company is advised by the Representative(s) that the Underwriters propose to make a public offering of their respective portions of the Offered Securities as soon after this Agreement has been entered into as in the Representative(s)’ judgment is advisable. The terms of the public offering of the Offered Securities are set forth in the Time of Sale Information and the Prospectus.

3. Purchase and Delivery. Payment for the Offered Securities shall be made in the funds and manner specified and at the time and place set forth in the Underwriting Agreement, upon delivery to the Representative(s) for the respective accounts of the several Underwriters of the Offered Securities, registered in such names and in such denominations as the Representative(s) shall request in writing not less than two full business days prior to the date of delivery. The Company shall not be obligated to deliver any Offered Securities except upon payment for all the Offered Securities to be purchased as herein provided.

The Company acknowledges and agrees that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to any offering of securities contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company or any other person. Additionally, no such Underwriter is advising the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any

8

jurisdiction. The Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and such Underwriters shall have no responsibility or liability to the Company with respect thereto. Any review by such Underwriters named in the Underwriting Agreement of the Company, the transactions contemplated thereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Company.

4. Conditions to Closing. The several obligations of the Underwriters hereunder are subject to the following conditions:

(a) Subsequent to the earlier of (x) the Time of Sale and (y) the execution and delivery of the Underwriting Agreement and prior to the Closing Date, there shall not have been any downgrading, nor any notice given of any intended or potential downgrading in the rating accorded any of the Company’s securities by Standard & Poor’s, a Division of The McGraw-Hill Companies, Inc. or Moody’s Investors Service;

(b) there shall not have occurred any change in the condition, financial or otherwise, or in the earnings, business or operations, of the Company and its subsidiaries, taken as a whole, from that set forth in the Time of Sale Information (excluding any amendment or supplement thereto) and the Prospectus, that is material and adverse and that makes it impracticable or inadvisable to market or deliver the Offered Securities on the terms and in the manner contemplated in the Prospectus; and

(c) the Representative(s) shall have received on the Closing Date a certificate, dated the Closing Date and signed by an executive officer of the Company, to the effect set forth in clause (b) above and to the effect that the representations and warranties of the Company contained in this Agreement are true and correct as of the Closing Date and that the Company has complied with all of the agreements and satisfied all of the conditions on its part to be performed or satisfied on or before the Closing Date.

The officer signing and delivering such certificate may rely upon the best of his knowledge as to proceedings threatened.

5. Covenants of the Company. In further consideration of the agreements of the Underwriters contained herein, the Company covenants as follows:

(a) The Company will file the final Prospectus with the Commission within the time periods specified by Rule 424(b) and Rule 430A, 430B or 430C under the Securities Act, as applicable, will file any Issuer Free Writing Prospectus (including the Term Sheet in the form of Schedule 4 hereto) to the extent required by Rule 433 under the Securities Act; and will file promptly all reports and any definitive proxy or information statements required to be filed by the Company with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act subsequent to the date of the Prospectus and for so long as the delivery of a prospectus (or, in lieu thereof, the notice referred to in Rule 173(a) under the Securities Act) is required in connection with the offering or sale of the Offered Securities; and the Company will furnish copies of the Prospectus and each Issuer Free Writing Prospectus (to the extent not previously delivered) to the Underwriters in New York City prior to 10:00 A.M., New York City time, on the business day next succeeding the date of this Agreement in such quantities as the Representative(s) may reasonably request. The Company will pay the registration fees for this offering within the time period required by Rule 456(b)(1)(i) under the Securities Act and in any event prior to the Closing Date.

(b) To furnish the Representative(s), without charge, a copy of the Registration Statement (including exhibits thereto) and for delivery to each other Underwriter a copy of the Registration Statement (without exhibits thereto) and, during the Prospectus Delivery Period (as defined below), as many copies of the Prospectus, any documents incorporated by reference therein and any supplements and amendments thereto or to the Registration Statement and each Issuer Free Writing Prospectus (if applicable) as the Representative(s) may reasonably request.

10

(c) During the Prospectus Delivery Period, before making, preparing, using, authorizing, approving, referring to or filing any Issuer Free Writing Prospectus, and before amending or supplementing the Registration Statement (other than an amendment relating exclusively to securities other than the Offered Securities) or the Prospectus with respect to the Offered Securities, to furnish to the Representative(s) a copy of each such proposed Issuer Free Writing Prospectus, amendment or supplement and, with respect to any such filing on or after the date hereof and prior to the Closing Date, not to make, prepare, use, authorize, approve, refer to or file any such Issuer Free Writing Prospectus or to file any such proposed amendment or supplement to which the Representative(s) reasonably object; provided, however, that the foregoing shall not apply to filings required to be made with the Commission in order to comply with the Exchange Act so long as any such filing is provided to the Representatives a reasonable amount of time in advance of such filing.

(d) If, during such period after the first date of the public offering of the Offered Securities as in the opinion of counsel for the Underwriters the Prospectus (or, in lieu thereof, the notice referred to in Rule 173(a) under the Securities Act) is required by law to be delivered in connection with sales by an Underwriter or dealer (the “Prospectus Delivery Period”), any event shall occur or condition exists as a result of which it is necessary to amend or supplement the Prospectus, the Time of Sale Information or any Issuer Free Writing Prospectus in order that the same not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus, the Time of Sale Information or any Issuer Free Writing Prospectus is delivered to a purchaser, not misleading, or if, in the opinion of the Company, it is necessary at any time to amend or supplement the Prospectus, the Time of Sale Information or any Issuer Free Writing Prospectus, as then amended or supplemented to comply with applicable law, forthwith to prepare and furnish, at its own expense, to the Underwriters either amendments or supplements to the Prospectus, the Time of Sale Information or any Issuer Free Writing Prospectus that will correct such untrue statement or omission or will effect such compliance.

(e) To endeavor to qualify, and to cooperate with the Underwriters in an endeavor to qualify, the Offered Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Representative(s) shall reasonably request and to pay all expenses (including reasonable fees and disbursements of one counsel for the Underwriters not to exceed $5,000) in connection with such qualification

11

and in connection with (i) the determination of the eligibility of the Offered Securities for investment under the laws of such jurisdictions as the Representative(s) may designate and (ii) any review of the offering of the Offered Securities by the Financial Industry Regulatory Authority, Inc.; provided, however that the Company need not qualify the Offered Securities for offer and sale in any jurisdiction where such qualification would, in the reasonable opinion of the Company, be unduly burdensome to the Company.

(f) To make generally available to the Company’s security holders and to the Representative(s) as soon as reasonably practicable an earnings statement covering a twelve month period beginning on the first day of the first full fiscal quarter after the date of this Agreement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act.

(g) During the period beginning on the date of the Underwriting Agreement and continuing to and including the later of (1) the Closing Date and (2) the termination of this Underwriting Agreement, not to offer, sell, contract to sell or otherwise dispose of any debt securities of the Company or warrants to purchase debt securities of the Company substantially similar to the Offered Securities (other than (i) the Offered Securities and (ii) medium-term notes and commercial paper issued in the ordinary course of business), without the prior written consent of the Representative(s).

(h) To pay all costs, expenses, fees and taxes incident to the preparation, printing, authorization, issuance, sale and delivery of the Offered Securities; the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, any Time of Sale Information and the Prospectus, including any amendments, supplements and exhibits thereto; the costs incident to the preparation, printing and filing of any document and any amendments and exhibits thereto required to be filed by the Company under the Exchange Act; the costs of distributing the Registration Statement as originally filed and each amendment and post-effective amendment thereof (including exhibits), any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus, any Time of Sale Information and any documents incorporated by reference in any of the foregoing documents; the costs of any filings with the Financial Industry Regulatory Authority, Inc. in connection with the Offered Securities; fees paid to rating agencies in connection with the rating of any debt securities; the fees and expenses of qualifying the Offered Securities under the securities laws of the jurisdictions as provided in this Section and of preparing and printing a Blue Sky Memorandum, and a memorandum concerning the legality of Offered

12

Securities as an investment (including fees and expenses of one counsel to the Underwriters in connection therewith); and all other costs and expenses incident to the performance of the Company’s obligations set forth herein; provided that, except as provided in this Section and in Section 10 hereof, the Underwriters shall pay their own costs and expenses, including the fees and expenses of their counsel and the expenses of advertising any offering of the Offered Securities made by the Underwriters.

(i) Record Retention. The Company will, pursuant to reasonable procedures developed in good faith, retain copies of each Issuer Free Writing Prospectus that is not filed with the Commission in accordance with Rule 433 under the Securities Act.

6. Certain Agreements of the Underwriters. Each Underwriter hereby represents and agrees that

(a) It has not and will not use, authorize use of, refer to, or participate in the planning for use of, any “free writing prospectus,” as defined in Rule 405 under the Securities Act (which term includes use of any written information furnished to the Commission by the Company and not incorporated by reference into the Registration Statement and any press release issued by the Company) other than (i) a free writing prospectus that, solely a result of use by such underwriter, would not trigger an obligation to file such free writing prospectus with the Commission pursuant to Rule 433 under the Securities Act, (ii) any Issuer Free Writing Prospectus listed on Schedule 3 to the Underwriting Agreement or prepared pursuant to Section 1(c) or Section 5(c) above (including any electronic road show), or (iii) any free writing prospectus prepared by such underwriter and approved by the Company in advance in writing (each such free writing prospectus referred to in clauses (i) or (iii), an “Underwriter Free Writing Prospectus.”) Notwithstanding the foregoing the Underwriters may use a term sheet substantially in the form of Schedule 4 to the Underwriting Agreement without the consent of the Company.

(b) It is not subject to any pending proceeding under Section 8A of the Securities Act with respect to the offering of the Offered Securities (and will promptly notify the Company if any such proceeding against it is initiated during the Prospectus Delivery Period).

7. Indemnification and Contribution. The Company agrees to indemnify and hold harmless each Underwriter and the directors, officers, employees and agents of each Underwriter and each person, if any, who controls such Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims,

13

damages and liabilities caused by (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representative(s) expressly for use therein.

Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to information relating to such Underwriter furnished to the Company by such Underwriter in writing through the Representative(s) expressly for use in the Registration Statement, the Prospectus or any amendments or supplements thereto, any Issuer Free Writing Prospectus or any Time of Sale Information.

In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to either of the two preceding paragraphs, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others entitled to indemnification pursuant to this Section 7 that the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel reasonably incurred related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees

14

and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Representative(s), in the case of parties indemnified pursuant to the second preceding paragraph, and by the Company, in the case of parties indemnified pursuant to the first preceding paragraph. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

If the indemnification provided for in the first or second paragraph in this Section 7 is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein in connection with any offering of Offered Securities, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Underwriters from the offering of the Offered Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and of the Underwriters in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Underwriters in connection with the offering of the Offered Securities shall be deemed to be in the same respective proportions as the total net proceeds from the offering of such Offered Securities (before deducting expenses) received by the Company bear to the total discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus Supplement, in respect thereof. The relative fault of the Company and of the Underwriters shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

15

The Company and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Offered Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or allegedly untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the respective principal amounts of the aggregate principal amount of Offered Securities purchased by each of such Underwriters under the Underwriting Agreement, and not joint. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

The indemnity and contribution provisions contained in this Section 7 and the representations and warranties of the Company contained herein shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter or by or on behalf of the Company, its directors or officers or any person controlling the Company and (iii) acceptance of and payment for any of the Offered Securities.

8. Termination. This Agreement shall be subject to termination in the Representative(s)’ absolute discretion, by notice given to the Company, if, after the earlier of the Time of Sale and the execution and delivery of the Underwriting Agreement and prior to the Closing Date, any of the following shall have occurred: (i) a suspension or material limitation in trading in securities generally on the New York Stock Exchange or on NYSE Alternext US; (ii) a suspension or material limitation in trading in the Company’s securities on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities declared by either Federal or New York State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States; (iv) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or

16

war or (v) the occurrence of any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (iv) or (v) in the judgment of the Representative(s) makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Offered Securities on the terms and in the manner contemplated in the Time of Sale Information and the Prospectus.

9. Defaulting Underwriters. If on the Closing Date any one or more of the Underwriters shall fail or refuse to purchase Offered Securities that it has or they have agreed to purchase on such date, and the aggregate amount of Offered Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate amount of the Offered Securities to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the amount of Offered Securities set forth opposite their respective names above bears to the aggregate amount of Offered Securities set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Representative(s) may specify, to purchase the Offered Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the amount of Offered Securities that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 9 by an amount in excess of one-ninth of such amount of Offered Securities without the written consent of such Underwriter. If on the Closing Date any Underwriter or Underwriters shall fail or refuse to purchase Offered Securities and the aggregate amount of Offered Securities with respect to which such default occurs is more than one-tenth of the aggregate amount of Offered Securities to be purchased on such date, and arrangements satisfactory to the Representative(s) and the Company for the purchase of such Offered Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company. In any such case either the Representative(s) or the Company shall have the right to postpone the Closing Date but in no event for longer then seven days, in order that the required changes, if any, in the Registration Statement and in the Prospectus or in any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

10. Payment of Expenses Upon Termination. If this Agreement shall be terminated by the Representative(s) because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, the Company will reimburse the Underwriters for all out-of-pocket expenses (including the reasonable fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with the Offered Securities, and upon demand, the Company shall pay the full amount to

17

the Representative(s). If this Agreement is terminated pursuant to Section 8 hereof or pursuant to Section 9 hereof, the Company shall not be obligated to reimburse the Underwriters for such expenses.

11. Miscellaneous. The Underwriting Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

12. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

FORM OF OPINION OF

COVINGTON & BURLING LLP

[Closing Date]

[Name[s] of Managing Underwriters]

As Representatives of the Underwriters

set forth on Schedule [        ] of the Underwriting Agreement

[c/o][name of lead manager]

[address of lead manager]

Ladies and Gentlemen:

We have acted as special counsel to Eli Lilly and Company, an Indiana corporation (the “Company”), in connection with the issuance and sale on the date hereof by the Company of $[amount] aggregate principal amount of its [designation of security] (the “Notes”) under the Indenture, dated as of February 1, 1991 (the “Indenture”), between the Company and Deutsche Bank Trust Company Americas (as successor to Citibank, N.A.), as trustee (the “Trustee”), and the purchase of the Notes by the several underwriters (the “Underwriters”) set forth on Schedule 1 of the Underwriting Agreement, dated             , 20         (the “Underwriting Agreement”), among the Company and                 ,                  and                 , as representatives of the Underwriters (the “Representatives”). This letter is delivered to you pursuant to Section 4(d) of the Standard Provisions (Debt Securities) attached to, and incorporated in, the Underwriting Agreement. Unless otherwise defined herein, capitalized terms used herein have the meanings provided in the Underwriting Agreement.

We have reviewed:

We also have reviewed such corporate records, certificates and other documents, and such questions of law, as we have deemed necessary or appropriate for the purposes of this opinion. The Underwriting Agreement, the Notes and the Indenture are collectively referred to as the “Documents.”

We have assumed that all signatures are genuine, that all documents submitted to us as originals are authentic and that all copies of documents submitted to us conform to the originals. We have assumed further that (i) the Company is a corporation duly organized, validly existing and in good standing under the laws of the State of Indiana and has all legal right, power and authority and, except as set forth in our opinion in paragraph 10 below, has obtained all authorizations and approvals of governmental authorities necessary (A) to issue and sell the Notes and (B) to execute, deliver and perform its obligations under the Documents, (ii) the issuance and sale of the Notes and the execution, delivery and performance by the Company of its obligations under the Documents have been duly authorized by the Company, (iii) the Notes have been duly executed and delivered by the Company (except to the extent that the execution and delivery thereof is governed by the laws of the State of New York), (iv) the Underwriting Agreement has been duly executed and delivered by the Company (except to the extent that the execution and delivery thereof is governed by the laws of the State of New York), and (v) the Indenture has been duly executed and delivered by the Company. We have assumed further that the Trustee and the Representatives have duly authorized, executed and delivered the Documents to which each is a party.

2

We have made no investigation for the purpose of verifying the assumptions set forth herein.

We have relied as to certain matters on information obtained from public officials, officers of the Company and other sources believed by us to be responsible, and on information regarding the Company contained in the Registration Statement and the Prospectus.

Our statement in paragraph 5 below as to stop orders and related proceedings is based solely on a review of the list of stop orders on the Commission’s website at http://www.sec.gov/litigation/stoporders.shtml at          a.m.(New York City time) on the date hereof.

As used in this opinion, all references to the “Registration Statement,” the “Preliminary Prospectus” and the “Prospectus” include all documents incorporated by reference therein, to the extent not modified or superseded by statements or other information in the Registration Statement, Preliminary Prospectus or Prospectus or in later filed material so incorporated. In addition, the qualification in paragraphs 5 and 9 of this letter “to the best of our knowledge” and “known to us” mean the actual knowledge, but not constructive or imputed knowledge, of the attorneys in our firm who have rendered legal services on behalf of our firm for the Company, without any representation or implication that any inquiry has been made with respect to such statements.

Based upon the foregoing, and subject to the qualifications set forth below, we are of the opinion that:

1. The Indenture is the valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other laws of general applicability relating to or affecting creditors’ rights and to general equity principles. The Indenture has been qualified under the Trust Indenture Act of 1939, as amended.

2. The Company has duly executed and delivered the Notes (insofar as the validity of such execution and delivery is governed by the law of the State of New York).

3. The Company has duly executed and delivered the Underwriting Agreement (insofar as the validity of such execution and delivery is governed by the law of the State of New York).

4. When the Notes have been (a) duly authenticated and delivered by the Trustee in accordance with the Indenture and (b) issued and delivered by the Company against payment of the purchase price therefor in accordance with the Underwriting Agreement, the Notes will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other laws of general applicability relating to or affecting creditors’ rights and to general equity principles and will be entitled to the benefits of the Indenture.

3

5. The Registration Statement is effective under the Securities Act, and, to the best of our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued under the Securities Act and no proceedings for that purpose have been instituted or are pending or threatened by the Commission.

6. The statements in the General Disclosure Package and the Prospectus under the captions “Description of the Notes” and “Description of Debt Securities,” insofar as such statements constitute summaries of the documents referred to therein, are accurate in all material respects and fairly summarize such documents.

7. The statements in the General Disclosure Package and the Prospectus under the caption “Material U.S. Federal Tax Considerations,” insofar as such statements constitute summaries of the laws, regulations, legal matters, or legal documents referred to therein, are accurate in all material respects and fairly summarize the matters referred to therein.

8. The Registration Statement, on the date of the effectiveness of the Registration Statement as provided in Rule 430B(f)(2) under the Securities Act, and the Prospectus, as of the date thereof (excluding (i) the financial statements, including the notes thereto, and the other financial data included therein and (ii) the Statement of Eligibility on Form T-1 filed as Exhibit 25.1 to the Registration Statement, as to which we express no opinion) complied as to form in all material respects with the requirements of the Securities Act and the rules and regulations of the Commission thereunder.

9. The issuance of the Notes and the execution and delivery of the Underwriting Agreement by the Company and the consummation by the Company of the transactions contemplated thereby in accordance with the terms thereof do not violate any New York or federal statute, law, rule or regulation known to us to which the Company is subject.

10. No consent, approval, authorization or other action by or filing with any governmental agency or instrumentality of the State of New York or the United States of America is required on the part of the Company for the issuance of the Notes or the execution and delivery of the Underwriting Agreement or the consummation of the transactions contemplated thereby in accordance with the terms thereof, except (i) those already obtained or made and (ii) those required under federal and state securities laws.

The foregoing opinions are subject to the following qualifications:

4

(b) We express no opinion as to any state securities or blue sky laws, rules or regulations or as to any federal or state anti-fraud statute, rule or regulation. To the extent we are passing upon the compliance of the Documents and the transactions contemplated thereby with federal securities laws, we have necessarily assumed the accuracy, completeness and fairness of the statements made or included in the General Disclosure Package and the Prospectus, except as set forth in our opinions in paragraphs 6 and 7 above.

(c) We express no opinion as to any legal requirements or restrictions applicable to the Underwriters or any investor.

(d) Our opinions in paragraphs 9 and 10 above are limited to laws and regulations that in our experience are normally applicable to transactions of the type contemplated by the Documents and do not extend to laws or regulations relating to, or to licenses, permits, approvals and filings necessary for, the conduct of the Company’s business or to any environmental laws or regulations.

(e) Except as specifically set forth in paragraph 7 above, we express no opinion as to any tax laws or the Employee Retirement Income Security Act of 1974, as amended, or any comparable state law.

In addition, in accordance with our understanding with the Company as to the scope of our services in connection with the offering of the Notes, as special counsel to the Company, we reviewed the Registration Statement, the General Disclosure Package and the Prospectus and participated in discussions with your representatives and those of the Company, your counsel and the Company’s accountants. On the basis of the information which was reviewed by us in the course of the performance of the services referred to above, considered in the light of our understanding of the applicable law and the experience we have gained through our practice

5

under the federal securities laws, we confirm to you that nothing which came to our attention in the course of such review has caused us to believe that: (a) the Registration Statement, on the date of effectiveness of the Registration Statement as provided in Rule 430B(f)(2) of the Securities Act, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not misleading, (b) the General Disclosure Package, as of the Time of Sale, contained any untrue statement of a material fact or omitted to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; or (c) the Prospectus, as of its date or as of the date hereof, contained or contains any untrue statement of a material fact or omitted or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

The limitations inherent in the independent verification of factual matters and the character of determinations involved in the registration process are such, however, that we do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, General Disclosure Package or the Prospectus, except as specified in paragraphs 6 and 7 above. Also, we do not express any opinion or belief as to the financial statements, including the notes thereto, and the other financial data included or deemed incorporated by reference in the Registration Statement, the General Disclosure Package or the Prospectus or with respect to the Statement of Eligibility on Form T-1 filed as Exhibit 25.1 to the Registration Statement.

We are members of the bar of the District of Columbia and the State of New York. We do not express any opinion herein on any law other than the law of the State of New York and, to the extent expressly referred to herein, the federal law of the United States of America.

This letter is given to you as Representatives of the several Underwriters and is solely for the benefit of the Underwriters. It may not be disclosed to or relied upon any other person without our written consent.

DEPUTY GENERAL COUNSEL OF COMPANY

[Closing Date]

[Name[s] of Managing Underwriters]

As Representatives of the Underwriters

set forth on Schedule [    ] of the Underwriting Agreement

[c/o][name of lead manager]

[address of lead manager]

Ladies and Gentlemen:

This opinion is being rendered to the Underwriters (as defined below) pursuant to the Underwriting Agreement (the “Underwriting Agreement”), dated             , 20        , between Eli Lilly and Company (the “Company”) and the underwriters named therein (the “Underwriters”), pursuant to which the Underwriters severally agreed to purchase, and the Company agreed to sell to the Underwriters, $[amount] aggregate principal amount of the Company’s [designation of security] (the “Notes”). I am the Secretary and Deputy General Counsel of the Company. This opinion is being rendered to the Underwriters and the Trustee (as defined below) at the request of the Company.

I have examined the corporate proceedings of the Company with respect to:

(a) the organization of the Company pursuant to its Amended Articles of Incorporation;

(b) the authorization of the execution by the Company of (1) the Indenture (the “Indenture”), dated as of February 1, 1991, between the Company and Deutsche Bank Trust Company Americas, as successor trustee (the “Trustee”) to Citibank, N.A., the original trustee and (2) the Underwriting Agreement;

(c) the authorization of the issuance of the Notes under the Indenture;

(d) the authorization of the sale of the Notes in accordance with the provisions of the Underwriting Agreement;

(e) the Company’s Registration Statement on Form S-3 (File No. 333-            ) relating to the registration under the Securities Act of 1933, as amended (the “Act”), of the offer and sale of certain debt securities (including the Notes) of the Company, as filed by the Company with the Securities and Exchange Commission (the “Commission”) on             , 20        , including the exhibits thereto and the Incorporated Documents (as defined below) (such Registration Statement, at the time it became effective on             , 20        , being hereinafter called the “Registration Statement”);

(f) the Company’s prospectus, dated             , 20        , as filed by the Company with the Commission pursuant to Rule 424(b) under the Act on             , 20         (such prospectus, including the Incorporated Documents, being hereinafter called the “Base Prospectus”);

(g) the Company’s preliminary prospectus supplement, dated             , 20        , as filed by the Company with the Commission pursuant to Rule 424(b) under the Act on             , 20         (such preliminary prospectus supplement, including the Base Prospectus attached thereto and the Incorporated Documents, being hereinafter called the “Preliminary Prospectus”); and

(h) the Company’s final prospectus supplement, dated             , 20        , as filed by the Company with the Commission pursuant to Rule 424(b) under the Act on             , 20         (such final prospectus supplement, including the Base Prospectus attached thereto and the Incorporated Documents, being hereinafter called the “Prospectus”).

As used herein, the term “Incorporated Documents,” when used with respect to the Registration Statement, the Base Prospectus, the Preliminary Prospectus or the Prospectus, as the case may be, means the documents filed by the Company with the Commission subsequent to December 31, 20         and incorporated or deemed to be incorporated by reference in the Registration Statement, the Base Prospectus, the Preliminary Prospectus or the Prospectus, as the case may be, as of such date pursuant to Item 12 of Form S-3.

In preparing this opinion, I have examined and relied upon, among other things, such certificates of public officials and of officers and employees of the Company and such originals or copies, certified or otherwise identified to my satisfaction, of corporate documents and records of the Company as I deemed necessary or appropriate for the purposes hereof.

2

On the basis of, and in reliance on, the foregoing and subject to the assumptions, exceptions, qualifications and limitations contained herein, I am of the opinion that:

3

I am a member of the bar of the State of Indiana, and I express no opinion as to matters governed by the laws of any other jurisdiction (other than the federal laws of the United States of America), except that I express no opinion with respect to federal securities laws or state securities or blue sky laws.

I hereby consent that Covington & Burling LLP and Davis Polk & Wardwell LLP may rely upon this opinion as if it were addressed to them.

4

The foregoing opinion is rendered as of the date hereof, and I assume no obligation to update such opinion to reflect any facts or circumstances which may hereafter come to my attention or any changes in the law which may hereafter occur.

The opinions expressed in this letter are solely for your benefit in connection with the issuance of the Notes and may not be used, disseminated or relied upon in any manner by you for any other purpose, or by any other person or entity for any purpose, without my prior written consent.

FORM OF OPINION OF

DAVIS POLK & WARDWELL LLP

[Closing Date]

[Name[s] of Managing Underwriters]

as Representative[s] of the several Underwriters named in

[Schedule 1 to] the Underwriting Agreement referred to below

[c/o][name of lead manager]

[address of lead manager]

Ladies and Gentlemen:

We have acted as counsel for you and the other several Underwriters named in Schedule 1 (the “Underwriters”) to the Underwriting Agreement dated             , 20         (the “Underwriting Agreement”), including the Standard Provisions (Debt Securities) incorporated by reference therein dated             , 20        , with Eli Lilly and Company, an Indiana corporation (the “Company”), under which you and such other Underwriters have severally agreed to purchase from the Company $[amount] aggregate principal amount of its [designation of security] (the “Notes”). The Notes are to be issued pursuant to the provisions of the Indenture dated as of February 1, 1991 (the “Indenture”) between the Company and Deutsche Bank Trust Company Americas, as successor trustee (the “Trustee”) to Citibank N.A. This opinion is being rendered to you pursuant to Section 4(f) of the Underwriting Agreement.

We have examined originals or copies of such documents, corporate records, certificates of public officials and other instruments as we have deemed necessary or advisable for the purpose of rendering this opinion.

We have also reviewed the Company’s registration statement on Form S-3 (Registration No. 333-            ) [and Amendment(s) No.      thereto] (including the documents incorporated by reference therein (the “Incorporated Documents”)) filed with the Securities and Exchange Commission (the “Commission”) pursuant to the provisions of the Securities Act of 1933, as amended (the “Act”), relating to the registration of securities (the “Shelf Securities”) to be issued from time to time by the Company and have participated in the preparation of the preliminary prospectus supplement dated             , 20         (the “Preliminary Prospectus Supplement”) relating to the Securities, [list free writing prospectuses, if any, that form part of the Disclosure Package to be covered by the opinion] [and] the prospectus supplement dated             , 20         relating to the Securities (the “Prospectus Supplement”). The registration statement became effective under the Act and the Indenture qualified under the Trust Indenture Act of 1939, as

amended (the “Trust Indenture Act”), upon the filing of the registration statement with the Commission on date of filing pursuant to Rule 462(e). The registration statement [as amended] at the date of the Underwriting Agreement, including the Incorporated Documents and the information deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430B under the Act, is hereinafter referred to as the “Registration Statement,” and the related prospectus (including the Incorporated Documents) dated             , 20         relating to the Shelf Securities is hereinafter referred to as the “Basic Prospectus.” The Basic Prospectus, as supplemented by [the Preliminary Prospectus Supplement], together with the free writing prospectus[es] set forth in Schedule 3 to the Underwriting Agreement for the Securities are hereinafter called the “Disclosure Package.” The Basic Prospectus, as supplemented by the Prospectus Supplement, in the form first used to confirm sales of the Securities (or in the form first made available by the Company to the Underwriters to meet requests of purchasers of the Securities under Rule 173 under the Act), is hereinafter referred to as the “Prospectus.”

In rendering the opinions expressed herein, we have, without independent inquiry or investigation, assumed that (i) all documents submitted to us as originals are authentic and complete, (ii) all documents submitted to us as copies conform to authentic, complete originals, (iii) all documents filed with or submitted to the Commission through its Electronic Data Gathering, Analysis and Retrieval (“EDGAR”) system (except for required EDGAR formatting changes) conform to the versions of such documents reviewed by us prior to such formatting, (iv) all signatures on all documents that we reviewed are genuine, (v) all natural persons executing documents had and have the legal capacity to do so, (vi) all statements in certificates of public officials and officers of the Company that we reviewed were and are accurate and (vii) all representations made by the Company as to matters of fact in the documents that we reviewed were and are accurate.

Capitalized terms used but not defined herein are used as defined in the Underwriting Agreement.

Based upon the foregoing, and subject to the additional assumptions and qualifications set forth below, we are of the opinion that:

(1) Assuming the due authorization, execution and delivery by the Company, the Indenture is a valid and binding agreement of the Company, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights

2

generally, concepts of reasonableness and equitable principles of general applicability, provided that we express no opinion as to [(x)] the enforceability of any waiver of rights under any usury or stay law [or (y) the validity, legally binding effect or enforceability of any provision that permits holders to collect any portion of stated principal amount upon acceleration of the Notes to the extent determined to constitute unearned interest].

(2) Assuming the due authorization of the Notes by the Company, the Notes, when executed and authenticated in accordance with the provisions of the Indenture and delivered to and paid for by the Underwriters pursuant to the Underwriting Agreement, will be valid and binding obligations of the Company, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability, and will be entitled to the benefits of the Indenture, provided that we express no opinion as to [(x)] the enforceability of any waiver of rights under any usury or stay law or [(y) the validity, legally binding effect or enforceability of any provision that permits holders to collect any portion of stated principal amount upon acceleration of the Notes to the extent determined to constitute unearned interest].

We have considered the statements included in the Disclosure Package under the captions “[Description of the Notes,]” “[Underwriting,]” “[Description of Debt Securities]” and “[Plan of Distribution]” and in the Prospectus under the captions “[Description of the Notes,]” “[Underwriting,]” “[Description of Debt Securities]” and “[Plan of Distribution]” insofar as they summarize provisions of the Indenture, the Notes and the Underwriting Agreement. In our opinion, such statements fairly summarize these provisions in all material respects.

In rendering the opinions in paragraphs (1) and (2) above, we have assumed that each party to the Indenture, the Underwriting Agreement and the Notes (the “Documents”) has been duly incorporated and is validly existing and in good standing under the laws of the jurisdiction of its organization. In addition, we have assumed that (i) the execution, delivery and performance by each party thereto of each Document to which it is a party, (a) are within its corporate powers, (b) do not contravene, or constitute a default under, the certificate of incorporation or bylaws or other constitutive documents of such party, (c) require no action by or in respect of, or filing with, any governmental body, agency or official and (d) do not contravene, or constitute a default under, any provision of applicable law or regulation or any judgment, injunction, order or decree or any

3

agreement or other instrument binding upon such party and (ii) each Document (other than the Underwriting Agreement) is a valid, binding and enforceable agreement of each party thereto, (other than as expressly covered above in respect of the Company).

We are members of the Bar of the State of New York and the foregoing opinion is limited to the laws of the State of New York and the federal laws of the United States of America. [Insofar as the foregoing opinion involves matters governed by the laws of Indiana, we have relied, without independent investigation, on the opinion of [name of counsel for the Company], counsel for the Company, delivered to you today pursuant to the Underwriting Agreement.]

This opinion is rendered solely to you and the other several Underwriters in connection with the Underwriting Agreement. This opinion may not be relied upon by you for any other purpose or relied upon by any other person (including any person acquiring Securities from the several Underwriters) or furnished to any other person without our prior written consent.

Very truly yours,

DAVIS POLK & WARDWELL LLP

[Closing Date]

[Name[s] of Managing Underwriters]

as Representative[s] of the several Underwriters named in

[Schedule 1 to] the Underwriting Agreement referred to below

[c/o][name of lead manager]

[address of lead manager]

Ladies and Gentlemen:

We have acted as counsel for you and the other several Underwriters named in Schedule 1 (the “Underwriters”) to the Underwriting Agreement dated             , 20         (the “Underwriting Agreement”), including the Standard Provisions (Debt Securities) incorporated by reference therein dated             , 20        , with Eli Lilly and Company, an Indiana corporation (the “Company”), under which you and such other Underwriters have severally agreed to purchase from the Company $[amount] aggregate principal amount of its [designation of security] (the “Notes”). This opinion is being rendered to you pursuant to Section 4(f) of the Underwriting Agreement.

We have reviewed the Company’s registration statement on Form S-3 (Registration No. 333-            ) [and Amendment Nos.      thereto] (including the documents incorporated by reference therein (the “Incorporated Documents”)) filed with the Securities and Exchange Commission (the “Commission”) pursuant to the provisions of the Securities Act of 1933, as amended (the “Act”), relating to the registration of securities (the “Shelf Securities”) to be issued from time to time by the Company and have participated in the preparation of [the preliminary prospectus supplement dated             , 20         (the “Preliminary Prospectus Supplement”) relating to the Securities,] [list free writing prospectuses, if any, that form part of the Disclosure Package to be covered by the opinion] [and] the prospectus supplement dated             , 20         relating to the Securities (the “Prospectus Supplement”). The registration statement [as amended] at the date of the Underwriting Agreement, including the Incorporated Documents and the information deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430B under the Act, is hereinafter referred to as the “Registration Statement,” and the related prospectus (including the Incorporated Documents) dated             , 20         relating to the Shelf Securities is hereinafter referred to as the “Basic Prospectus.” The Basic Prospectus, as supplemented by [the Preliminary Prospectus Supplement], together with the free writing prospectus[es] set forth in Schedule 3 to the Underwriting Agreement for the Securities are hereinafter called the “Disclosure Package.” The Basic Prospectus, as supplemented by the Prospectus Supplement, in the form first used to confirm sales of the Securities (or in the form first made available by the Company to the Underwriters to meet requests of purchasers of the Securities under Rule 173 under the Act), is hereinafter referred to as the “Prospectus.”

We have, without independent inquiry or investigation, assumed that all documents filed with or submitted to the Commission through its Electronic Data Gathering, Analysis and Retrieval (“EDGAR”) system (except for required EDGAR formatting changes) conform to the versions of such documents reviewed by us prior to such formatting.

The primary purpose of our professional engagement was not to establish or confirm factual matters or financial, accounting or quantitative information. Furthermore, many determinations involved in the preparation of the Registration Statement, the Disclosure Package and the Prospectus are of a wholly or partially non-legal character or relate to legal matters outside the scope of our opinion separately delivered to you today in respect of certain matters under the laws of the State of New York and the federal laws of the United States of America. As a result, we are not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Disclosure Package or the Prospectus, and we have not ourselves checked the accuracy, completeness or fairness of, or otherwise verified, the information furnished in such documents (except to the extent expressly set forth in our opinion letter separately delivered to you today as to statements included in the Disclosure Package under the captions “[Description of the Notes,]” “[Underwriting,]” “[Description of Debt Securities]” and “[Plan of Distribution]” and in the Prospectus under the captions “[Description of the Notes,]” “[Underwriting,]” “[Description of Debt Securities]” and “[Plan of Distribution]”). However, in the course of our acting as counsel to you in connection with the review of the Registration Statement, the Disclosure Package and the Prospectus, we have generally reviewed and discussed with your representatives and with certain officers and employees of, and counsel and independent public accountants for, the Company the information furnished, whether or not subject to our check and verification. We have also reviewed and relied upon certain corporate records and documents, letters from counsel and accountants and oral and written statements of officers and other representatives of the Company and others as to the existence and consequence of certain factual and other matters.

On the basis of the information gained in the course of the performance of the services rendered above, but without independent check or verification, except as stated above:

(i) the Registration Statement and the Prospectus appear on their face to be appropriately responsive in all material respects to the requirements of the Act and the applicable rules and regulations of the Commission thereunder and

(ii) nothing has come to our attention that causes us to believe that, insofar as relevant to the offering of the Securities:

(a) on the date of the Underwriting Agreement, the Registration Statement contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading,

(b) at the Time of Sale, [[            ] [a.m.][p.m.] (New York City time)], the Disclosure Package contained any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or

(c) the Prospectus as of the date of the Underwriting Agreement or as of the date hereof contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

In providing this letter to you and the other several Underwriters, we have not been called to pass upon, and we express no view regarding the financial statements or financial schedules or other financial or accounting data included in the Registration Statement, the Disclosure Package or the Prospectus or the Statement of Eligibility of the Trustee on Form T-1. In addition, we express no view as to the conveyance of the Disclosure Package or the information contained therein to investors.

This letter is delivered solely to you and the other several Underwriters in connection with the Underwriting Agreement. This letter may not be relied upon by you or the other several Underwriters for any other purpose or relied upon by any other person (including any person acquiring Securities from the several Underwriters) or furnished to any other person without our prior written consent.

Very truly yours,

Exhibit 4.4

[SEAL]

This is one of the Securities of the series designated therein issued under the within-mentioned Indenture.

[REVERSE OF NOTE]

This Note is one of a duly authorized issue of a series of debt securities (the “Securities”) of the Company, designated as its 2.500% Notes due 2060 (the “Notes”). The Securities, including the Notes, are all issued or to be issued under and pursuant to the Indenture, to which Indenture, and all Board Resolutions and Officers’ Certificates as provided therein, reference is hereby made for a description of the rights, limitation of rights, obligations, duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes, and the terms upon which the Notes are, and are to be, authenticated and delivered. The Notes are initially limited to eight hundred and fifty million Dollars ($850,000,000) in aggregate principal amount; provided, however, that the Company may at any time issue additional Securities under the Indenture in unlimited amounts having the same terms as the Notes other than the date of original issuance and the first Interest Payment Date applicable thereto, and such Securities shall be treated as a single series with the Notes for all purposes under the Indenture.

This Note shall constitute part of the Company’s unsecured and unsubordinated obligations and shall rank equally in right of payment with all of the Company’s other existing and future unsecured and unsubordinated indebtedness. This Note shall be issuable in fully registered form only, in minimum denominations of two thousand Dollars ($2,000) and any integral multiples of one thousand Dollars ($1,000) in excess of that amount.

In case an Event of Default shall have occurred and be continuing with respect to this Note, the principal hereof may be declared due and payable, and upon such declaration shall become due and payable, in the manner, with the effect, and subject to the conditions provided in the Indenture. The Indenture permits the Holders of at least a majority in aggregate principal amount of the Notes at the time outstanding to, on behalf of the Holders of all of the Notes and in the manner and subject to the provisions of the Indenture, waive certain past defaults and rescind and annul such past declarations and their consequences under the Indenture.

The Indenture contains provisions permitting the Company and the Trustee, with consent of the Holders of not less than a majority of the aggregate principal amount of the Notes at the time outstanding, evidenced as provided in the Indenture, to execute supplemental indentures for the purpose of 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 Notes or of modifying in any manner the rights of the Holders of the Notes; provided, however, that no such supplemental indenture shall (i) extend the fixed maturity, or the earlier optional date of maturity, if any, of any Note, or reduce the principal amount thereof or the premium thereon, if any, or reduce the rate or extend the time of payment of interest, if any, thereon or make the principal thereof or premium, if any, or interest, if any, thereon payable in any currency other than as provided pursuant to the Indenture or this Note, without the consent of the Holders of each Note so affected; or (ii) reduce the aforesaid percentage of the Notes, the Holders of which are required to consent to any such supplemental indenture, without the consent of the Holders of all Notes then outstanding.

The Notes shall not be entitled to the benefit of any mandatory redemption, sinking fund or analogous provisions.

Upon such notice as specified below and in accordance with the Indenture and the terms of this Note, the Notes are subject to redemption, in whole or in part, at the election of the Company at any time or from time to time, on a date fixed for redemption (a “Redemption Date”) prior to the Par Call Date and at a “redemption price” equal to the greater of the following amounts:

plus, in each case, unpaid interest accrued on such Notes to, but excluding, such Redemption Date. If the Company redeems all or any part of the Notes on or after the Par Call Date, it shall pay a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest hereon.

Notwithstanding the foregoing, installments of interest on the Notes that are due and payable on each Interest Payment Date falling on or prior to a Redemption Date shall be payable on such Interest Payment Date to the Holder(s) as of the close of business on the Regular Record Date immediately preceding such Interest Payment Date.

The Company shall mail notice of each redemption at least 10 days but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed. Each notice of redemption shall (i) specify the Redemption Date and the redemption price at which the Notes are to be redeemed, (ii) state the applicable conditions precedent to such redemption, if any, as described below, and (iii) state that payment of the redemption price of the Notes to be redeemed, together with interest accrued thereon to the Redemption Date (except that if such Redemption Date is an Interest Payment Date, such interest due on such date shall be payable to the Holder on the Regular Record Date for such Interest Payment Date), will be made at the office or agency to be maintained by the Company in accordance with Section 5.02 of the Indenture (or, if desired by the Company, at the principal office of the Trustee) upon presentation and surrender of such Notes and that from and after said date any interest thereon will cease to accrue.

Any notice of redemption may, at the Company’s discretion, be subject to one or more conditions precedent, including completion of a corporate transaction. In such event, the related notice of redemption shall describe each such condition and, if applicable, shall state that, at the Company’s 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 shall be satisfied (or waived by the Company in its sole discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been

satisfied or waived by the Redemption Date, or by the Redemption Date so delayed. If any such redemption has been rescinded or delayed, the Company shall provide written notice to the Trustee prior to the close of business two Business Days prior to the Redemption Date and shall deliver a written request to the Trustee to promptly provide such notice to each Holder, and upon receipt the Trustee shall provide such notice to each Holder. Subject to any delay in the Redemption Date or rescission of the notice of redemption as described above, once notice of redemption is mailed, the Notes called for redemption shall become due and payable on the applicable Redemption Date at the applicable redemption price.

“Comparable Treasury Issue” means, for the Notes, the United States Treasury security selected by the Reference Treasury Dealer as having a maturity comparable to the remaining term of such Notes to be redeemed (assuming for this purpose that the Notes matured on the Par Call Date) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such Notes.

“Comparable Treasury Price” means, with respect to any Redemption Date prior to the Par Call Date, (A) if the Company obtains five or more Reference Treasury Dealer Quotations for such Redemption Date, the average of such Reference Treasury Dealer Quotations after excluding the highest and lowest of such Reference Treasury Dealer Quotations, (B) if the Company obtains fewer than five but more than one Reference Treasury Dealer Quotations, the average of such Reference Treasury Dealer Quotations, or (C) if the Company obtains only one Reference Treasury Dealer Quotation, such Reference Treasury Dealer Quotation.

“Par Call Date” means March 15, 2060.

“Reference Treasury Dealer” means (A) each of BNP Paribas Securities Corp., Citigroup Global Markets Inc., J.P. Morgan Securities LLC and Morgan Stanley & Co. LLC (or their respective affiliates that are Primary Treasury Dealers), and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in the United States (a “Primary Treasury Dealer”), the Company shall substitute therefor another Primary Treasury Dealer, and (B) any other Primary Treasury Dealer(s) selected by the Company.

“Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any Redemption Date prior to the Par Call Date, the average, as determined by the Company, of the bid and ask prices for the Comparable Treasury Issue for such Notes (expressed in each case as a percentage of the principal amount of the Notes) quoted in writing to the Company by such Reference Treasury Dealer at 5:00 p.m. (New York City time) on the third Business Day preceding such Redemption Date.

“Treasury Rate” means, with respect to any Redemption Date prior to the Par Call Date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of the principal amount of the Notes to be redeemed) equal to the Comparable Treasury Price for such Redemption Date.

On and after any Redemption Date, interest shall cease to accrue on the Notes or any portion of the Notes called for redemption (unless the Company defaults in the payment of the redemption price therefor). Before any Redemption Date, the Company shall deposit with a Paying Agent (or the Trustee) money sufficient to pay the redemption price of the Notes to be redeemed on such date. If fewer than all of the Notes are to be redeemed, then the Notes to be redeemed shall be selected by lot by the Depositary, in the case of Notes represented by a Global Security, or by the Trustee by a method the Trustee deems to be fair and appropriate, in the case of Notes that are not represented by a Global Security. The Notes are subject to the defeasance provisions set forth in Section 12.02 of the Indenture.

The Company shall not pay any additional amounts on any of the Notes to any person, including any Holder who is not a United States person in respect of any tax, assessment or governmental charge withheld or deducted.

No reference herein to the Indenture and no provision of this Note or of the Indenture or of any Board Resolution shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and premium, if any, and interest on this Note at the times and places and at the rate and in the coin and currency herein prescribed.

This Note is transferable by the Holder hereof in person or by his or her attorney duly authorized in writing on the books of the Company at the office or agency to be maintained by the Company for that purpose in The City of New York, but only in the manner, subject to the limitations and upon payment of any tax or governmental charge for which the Company may require reimbursement as provided in the Indenture, and upon surrender and cancellation of this Note. Upon any registration of transfer, a new registered Note or Notes, of authorized denomination or authorized denominations and like tenor and terms, and in the same aggregate principal amount, shall be issued to the transferee in exchange therefor.

The Company, the Trustee, any Paying Agent and any Security Registrar may deem and treat the Holder hereof as the absolute owner of this Note (whether or not this Note shall be overdue and notwithstanding any notations of ownership or other writing hereon made by anyone other than the Security Registrar) for the purpose of receiving payment of or on account of the principal hereof and premium, if any, and interest due hereon as herein provided and for all other purposes, and none of the Company, the Trustee, any Paying Agent or any Security Registrar shall be affected by any notice to the contrary.

No recourse shall be had for the payment of the principal of or premium, if any, or interest on this Note, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture or any supplemental indenture thereto or any Board Resolution, against any Person other than the Company or against any incorporator, stockholder, officer or director, past, present or future, as such, of the Company or any other Person, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issuance of this Note, expressly waived and released.

This Note shall be governed by and construed in accordance with the laws of the State of New York.
