On February 8, 2017, Microchip Technology Incorporated, a Delaware corporation (the “Company”), entered into Amendment No. 2 to Amended and Restated Credit Agreement (the “Amendment”) with the lenders party thereto and JPMorgan Chase Bank, N.A., as Administrative Agent (the “Administrative Agent”), which amends that certain Amended and Restated Credit Agreement, dated as of June 27, 2013, as amended and restated as of February 4, 2015, by and among the Company, the lenders from time to time party thereto and the Administrative Agent (as amended, restated, supplemented or otherwise modified from time to time, the “Credit Agreement”).

The Amendment, among other things, provides for the grant of a security interest by the Company and the subsidiary guarantors in substantially all of their personal property pursuant to a Pledge and Security Agreement, dated as of February 8, 2017 (the Security Agreement”), by and among the Company, the subsidiary guarantors party thereto and the Administrative Agent, to secure the obligations under the Credit Agreement. The Amendment also increases the maximum total leverage ratio from 4.50 to 1.00 to 5.00 to1.00 and permits the Company, at its option in connection with certain acquisitions and subject to the terms and conditions provided in the Amendment, to increase the maximum ratio permitted thereunder to 5.50 to 1.00 for a period of four consecutive fiscal quarters, with a step down to 5.25 to 1.00 for a period of three consecutive fiscal quarters. The Company may utilize this increase option only one time during the term of the Credit Agreement. In addition, the maximum senior leverage ratio was increased from 3.00 to 1.00 to 3.50 to 1.00.

The Amendment amends the existing increase option, permitting the Company, subject to certain requirements, to arrange with existing lenders and/or new lenders for them to provide additional commitments (which commitments may be for revolving loans or term loans) up to an amount such that, after giving effect to any such increase, the senior leverage ratio is equal to or less than 2.50 to 1.00. The Amendment also permits the prepayment or repurchase of a portion of the Company’s 2.125% Junior Subordinated Convertible Debentures due 2037 with proceeds from the issuance of convertible junior subordinated notes due 2037, subject to certain conditions.

Certain of the lenders under the Credit Agreement and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with the Company or the Company’s affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions.

Additional details of the Credit Agreement were previously disclosed in the Company’s Current Reports on Form 8-K filed with the Securities and Exchange Commission on February 4, 2015 and December 7, 2015, and are incorporated herein by reference.

The foregoing description of the Amendment and the Security Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Amendment and the Security Agreement, copies of which are filed as Exhibit 10.1 and Exhibit 10.2, respectively, hereto and incorporated herein by reference.
