On August 3, 2012, Jabil Circuit, Inc. (the “Company”) completed its offering (the “Offering”) of an aggregate principal amount of $500.0 million 4.700% senior unsecured notes due 2022 (the “Notes”) pursuant to the Company’s registration statement on Form S-3 (Registration Statement No. 333-177559), which was automatically effective when filed with the Securities and Exchange Commission on October 27, 2011 (the “Registration Statement”).

The Notes were issued pursuant to an Indenture dated as of January 16, 2008, by and between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Indenture”), as supplemented by the Officers’ Certificate dated August 3, 2012, that was delivered by certain of the Company’s officers pursuant to Sections 1.2, 3.1 and 3.3 of the Indenture (the “Officers’ Certificate”).

The Notes will mature on September 15, 2022. Interest on the Notes will be payable on March 15 and September 15 of each year, beginning on March 15, 2013. The Notes are senior unsecured obligations of the Company and rank equally with all other existing and future senior unsecured debt obligations.

The Company may redeem all or any part of the Notes at its option at any time prior to their maturity by paying a redemption price equal to the greater of (plus, in each case, accrued and unpaid interest thereon to, but not including, the redemption date): (i) 100% of the aggregate principal amount of the Notes to be redeemed or (ii) the sum of the present values of the remaining scheduled payments on the Notes discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the treasury rate plus 50 basis points.

The Indenture contains certain covenants, including, but not limited to, covenants limiting the Company’s ability and/or its subsidiaries’ ability to: create certain liens; enter into sale and leaseback transactions; create, incur, issue, assume or guarantee any funded debt (applicable only to the Company’s “restricted subsidiaries”); guarantee any of the Company’s indebtedness (applicable only to the Company’s subsidiaries); and consolidate or merge with, or convey, transfer or lease all or substantially all of its assets to another person. The Indenture also contains a covenant regarding the repurchase by the Company of the Notes upon a “change of control repurchase event.”

The Company used the Offering’s net proceeds (i) to repay outstanding borrowings under its five-year unsecured revolving credit facility and (ii) for general corporate purposes.
