The information provided in Item 2.03 below is incorporated herein by reference.

The information provided in Item 2.03 below is incorporated herein by reference.

On November 26, 2013, ViaSat, Inc. (“ViaSat”) entered into a senior secured Credit Agreement (the “Credit Facility”) by and among ViaSat, Union Bank, N.A. (as administrative agent and collateral agent), and the other lenders party thereto. The Credit Facility refinances and replaces in its entirety ViaSat’s Fifth Amended and Restated Revolving Loan Agreement, dated as of May 9, 2012, by and among ViaSat, Union Bank, N.A. (as administrative agent and collateral agent), and the other lenders party thereto, as amended (the “Prior Facility”). The Prior Facility was terminated and discharged in connection with the entry into the Credit Facility.

The Credit Facility provides for a revolving line of credit of $500.0 million (including up to $150.0 million of letters of credit). Commitments under the revolving line of credit terminate on November 26, 2018. Borrowings under the Credit Facility bear interest, at ViaSat’s option, at either (1) the highest of (a) the Federal Funds rate plus 0.50%, (b) the Eurodollar rate plus 1.00% or (c) the administrative agent’s prime rate as announced from time to time, or (2) the Eurodollar rate plus, in the case of each of (1) and (2), an applicable margin that is based on ViaSat’s total leverage ratio. The Credit Facility is required to be guaranteed by certain significant domestic subsidiaries of ViaSat (as defined in the Credit Facility) and is secured by substantially all of ViaSat’s and any subsidiary guarantor’s assets. At the closing of the Credit Facility, none of ViaSat’s subsidiaries guaranteed the Credit Facility.

The Credit Facility contains financial covenants regarding a maximum total leverage ratio and a minimum interest coverage ratio. In addition, the Credit Facility contains covenants that restrict, among other things, ViaSat’s ability to sell assets, make investments and acquisitions, make capital expenditures, grant liens, pay dividends and make certain other restricted payments. The Credit Facility also contains customary events of default. Upon the occurrence and during the continuance of an event of default, the lenders may declare all outstanding amounts under the Credit Facility immediately due and payable, and may terminate commitments to make any additional advances thereunder.

Certain of the lenders under the Credit Facility and the Prior Facility, and their respective affiliates, have performed, and may in the future perform, for ViaSat and its affiliates various commercial banking, investment banking, financial advisory or other services, for which they have received and may in the future receive customary compensation and expense reimbursement.

The description of the Credit Facility contained herein does not purport to be complete and is qualified in its entirety by reference to the complete text of the Credit Facility, which is attached hereto as an exhibit to this report and is incorporated herein by reference.
