On March 11, 2011, Esterline Technologies Corporation (“Esterline”) entered into a Credit Agreement with certain of its subsidiaries, Wells Fargo Bank, National Association, as Administrative Agent, and the lenders party thereto (the “Credit Agreement”) to provide debt financing in the form of a revolving loan facility in an aggregate amount at any one time outstanding not to exceed $460,000,000 (including a letter of credit subfacility not to exceed $100,000,000 and swingline subfacility not to exceed $15,000,000) (the “Credit Facility”). The Credit Facility proceeds will be used to refinance certain existing indebtedness of Esterline, to pay related fees and expenses and for working capital and other general corporate purposes. Subject to the satisfaction of certain conditions in the Credit Agreement (including obtaining commitments of lenders), Esterline has the right at any time prior to the maturity date of the Credit Facility to incur additional indebtedness under this Credit Agreement in the form of (i) new term loan facilities under this Credit Agreement and/or (ii) an increase to the revolving loan facility by an aggregate principal amount for all such term loans and revolving loan facility increases of up to $250,000,000.
