Ladies and Gentlemen:
I am the Secretary and Deputy General Counsel of Eli Lilly and Company, an Indiana corporation
(the Company). I am rendering this opinion in connection with the proposed issuance, by
the Company, of $1,000,000,000 aggregate principal amount of the Companys 5.20% Notes due 2017,
$700,000,000 aggregate principal amount of the Companys 5.50% Notes due 2027 and $800,000,000
aggregate principal amount of the Companys 5.55% Notes due 2037 (collectively, the Debt
Securities) pursuant to a prospectus supplement (the Prospectus Supplement) to the
prospectus contained in the Companys Registration Statement (the Registration Statement)
on Form S-3 (File No. 333-141075) filed with the U.S. Securities and Exchange Commission (the
Commission) on March 5, 2007 under the Securities Act of 1933, as amended (the
Securities Act), and pursuant to an Indenture, dated February 1, 1991, between the
Company and Citibank, N.A., as Trustee (the Indenture) and an Underwriting Agreement (the
Underwriting Agreement), dated March 7, 2007, between the Company and, as representatives
of the several underwriters named therein, Credit Suisse Securities (USA) LLC, Deutsche Bank
Securities Inc., J.P. Morgan Securities Inc. and Goldman, Sachs & Co.
I have examined and am familiar with originals, or copies certified or otherwise identified to my
satisfaction, of such documents, corporate records, certificates of officers of the Company and of
public officials and such other instruments as I have deemed necessary or appropriate as a basis
for the opinions expressed below, including the Registration Statement, the Companys Amended
Articles of Incorporation, the Companys By-Laws, the Indenture, the Debt Securities and the
Underwriting Agreement.
For purposes of the opinions expressed below, I have assumed, without independent investigation,
that (i) the Indenture and the Underwriting Agreement have been duly authorized, executed and
delivered by the parties thereto other than the Company and constitute valid and binding
obligations of the parties thereto other than the Company, enforceable against each of them in
accordance with their respective terms; and (ii) the certificates representing the Debt Securities
will conform as to form to the form of global notes examined by me. I have also assumed, without
independent investigation, the genuineness and authenticity of all documents submitted to me as
originals, the conformity to originals of all documents submitted to me as copies thereof and the
due execution and delivery of all documents where due execution and delivery are prerequisites to
the effectiveness thereof.
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:
| 1. | The Company is a corporation duly organized and validly existing under the laws of the State of Indiana. |
| 2. | Each of the Indenture and the Underwriting Agreement has been duly and validly authorized, executed and delivered by the Company. |
| 3. | The Company has duly authorized the issuance of the Debt Securities, and the Company has full corporate power and authority to issue the Debt Securities and to perform its obligations under the Debt Securities, the Indenture and the Underwriting Agreement. |
I am a member of the bar of the State of Indiana and express no opinion as to the laws of any other
jurisdiction.
I hereby consent that Dewey Ballantine LLP may rely upon this opinion as if it were addressed to
them.
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.
I hereby consent to the incorporation by reference of this opinion into the Registration Statement
and to the reference to my name under the heading Legal Matters in the prospectus included in the
Registration Statement. In giving such consent, I do not admit that I come within the category of
persons whose consent is required under Section 7 of the Securities Act or the rules and
regulations of the Commission.
Yours truly,
James B. Lootens
