Re: Registration Statement on Form S-3

Ladies and Gentlemen:

We refer to the Registration Statement on Form S-3 (the “Registration Statement”) being filed by Jabil Inc., a Delaware corporation (the “Company”), with the Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended (the “Securities Act”), relating to the registration of an unlimited amount of:

(i) debt securities of the Company (the “Debt Securities”), which may be secured or unsecured, senior or subordinated and issued in one or more series;

(ii) shares of the Company’s preferred stock, par value $0.001 per share (the “Preferred Stock”), which may be represented by depositary shares (the “Depositary Shares”);

(iii) shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”);

(iv) warrants to purchase Debt Securities, Preferred Stock, Common Stock or Units (as defined below) (the “Warrants”); and

(v) units, each consisting of two or more types of the securities listed in clauses (i) through (iv) above (the “Units”).

The Debt Securities, the Preferred Stock, the Depositary Shares, the Common Stock, the Warrants and the Units are collectively referred to herein as the “Securities.”

Unless otherwise specified in the applicable prospectus supplement:

(1) the Debt Securities will be issued under the indenture, dated as of January 16, 2008 (the “Indenture”), between the Company (formerly known as Jabil Circuit, Inc.) and U.S. Bank National Association (successor in interest to The Bank of New York Mellon Trust Company, N.A. ), as trustee (the “Trustee”);

(2) the Preferred Stock will be issued in one or more series and the relative powers, designations, preferences, privileges, rights and qualifications, limitations or restrictions of each series of Preferred Stock will be set forth in a certificate of designation (each, a “Certificate of Designation”);

(3) the Depositary Shares will be issued under one or more deposit agreements (each, a “Deposit Agreement”) between the Company and a depositary agent (each, a “Depositary Agent”);

(4) the Warrants will be issued under one or more warrant agreements (each, a “Warrant Agreement”) to be entered into between the Company and a warrant agent (each, a “Warrant Agent”); and

(5) the Units will be issued pursuant to one or more unit agreements (each, a “Unit Agreement”), to be entered into by the Company and the other parties named therein;

in each case substantially in the form that has been or will be filed as an exhibit to the Registration Statement. We refer to the Indenture, any series of Debt Securities, any supplemental indenture or officers’ certificate establishing the form and terms of the Debt Securities of any series, any Deposit Agreement, any Warrant Agreement, any Unit Agreement and any issue of Depositary Shares, Warrants or Units collectively as the “Opinion Documents.”

This opinion letter is being delivered in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

We have examined the Registration Statement, the exhibits thereto, the certificate of incorporation of the Company, as amended to the date hereof (the “Charter”), the bylaws of the Company, as amended to the date hereof (the “Bylaws”), and the resolutions (the “Resolutions”) adopted by the board of directors of the Company (the “Board”) relating to the Registration Statement. We have also examined originals, or copies of originals certified to our satisfaction, of such agreements, documents, certificates and statements of the Company and others, and have examined such questions of law, as we have considered relevant and necessary as a basis for this opinion letter. We have assumed the authenticity of all documents submitted to us as originals, the genuineness of all signatures, the legal capacity of all persons and the conformity with the original documents of any copies thereof submitted to us for examination. As to facts relevant to the opinions expressed herein, we have relied without independent investigation or verification upon, and assumed the accuracy and completeness of, certificates, letters and oral and written statements and representations of public officials and officers and other representatives of the Company.

Based on and subject to the foregoing and the other limitations, qualifications and assumptions set forth herein, we are of the opinion that:
