On August 15, 2013, we and certain of our direct and indirect Domestic Subsidiaries, Smith & Wesson Corp., SWSS LLC, Fox Ridge Outfitters, Inc., Bear Lake Holdings, LLC, O.L. Development, Inc., Thompson/Center Arms Company, LLC, and Smith & Wesson Distributing, Inc., entered into an unsecured credit agreement (the “Credit Agreement”) with certain lenders, TD Bank, N.A., as administrative agent, and TD Securities (USA) LLC, as sole lead arranger and sole bookrunner. Capitalized terms not otherwise defined herein will have the meanings set forth in the Credit Agreement. The Credit Agreement is filed herewith as Exhibit 10.104. The Credit Agreement provides for the following:

1. A revolving line of credit in the amount of $75 million at any one time. Subject to the satisfaction of certain terms and conditions described in the Credit Agreement, we have an option to increase the revolving line of credit by an amount not exceeding $100 million. Each Loan under the revolving line of credit bears interest at either the Base Rate, plus the Applicable Rate or the LIBOR Rate for the Interest Period in effect for such borrowing, plus the Applicable Rate. The revolving line of credit matures on the earlier of December 15, 2016, or the date that is six months in advance of the maturity of any Permitted Notes under the Credit Agreement. The Notes evidencing the revolving line of credit are filed herewith as part of Exhibit 10.105.

2. A swingline facility in the maximum amount of $5 million at any one time (subject to availability under the revolving line of credit). Each Swingline Loan bears interest at the Base Rate, plus the Applicable Rate. The Note evidencing the Swingline Loan is filed herewith as part of Exhibit 10.105.

The Credit Agreement contains customary limitations, including, without limitation, limitations on indebtedness; limitations on liens; limitations on fundamental changes to business or organizational structure; limitations on investments, loans, advances, guarantees, and acquisitions; limitations on asset sales; limitations on dividends, stock repurchases, stock redemptions, and the redemption or prepayment of other debt; and limitations on transactions with affiliates. We and our Domestic Subsidiaries are also subject to financial covenants, including, without limitation, a minimum consolidated fixed charge coverage ratio and a maximum consolidated leverage ratio.

The Credit Agreement also contains customary events of default, including, without limitation, nonpayment of principal, interest, fees, or other amounts when due; violation of covenants; breaches of representations or warranties; cross defaults; change of control; insolvency; bankruptcy events; and material judgments. Some of these events of default allow for grace periods or are qualified by materiality concepts. Upon the occurrence of an event of default, the outstanding obligations under the Credit Agreement may be accelerated and become due and payable immediately.

The foregoing is a summary only and does not purport to be a complete description of all of the terms, provisions, covenants, and agreements contained in the Credit Agreement and the Notes, and is subject to and qualified in its entirety by reference to the full text of such documents, which are filed herewith as Exhibits 10.104 and 10.105, respectively, and are hereby incorporated by reference into this Item 2.03.
