[1] On February 6, 2013, the Company refinanced its credit facilities and entered into (i) a credit agreement (the "Term Loan Agreement") with various lenders and Guggenheim Corporate Funding, LLC, as agent (the "Agent") that provides for a $165,000 term loan facility and (ii) a credit agreement with various lenders and Wells Fargo Bank, National Association (the "Revolving Loan Agreement") that provides for a $50,000 asset-based revolving borrowing base credit facility, with a $10,000 subfacility (or the Sterling equivalent) for certain of our United Kingdom subsidiaries, a $10,000 subfacility for letters of credit and a $5,000 subfacility for swingline loans. On February 6, 2013, in connection with entering into the Term Loan Agreement and the Revolving Loan Agreement, the Amended and Restated Credit Agreement, dated as of June 27, 2011 and amended on January 6, 2012 and March 22, 2012, by and among the lenders from time to time party thereto and Morgan Stanley Senior Funding, Inc., as administrative agent, lead arranger and sole book-runner, which had an outstanding balance of $183,400 was paid off and terminated, which resulted in the write-off of approximately $10,300 of deferred financing costs and note discounts. On December 31, 2013, the Company repaid $14,200 of its term loans from the proceeds of the Sale/Leaseback, (see (c) below) of the Company's facility located in State College, Pennsylvania. On July 5, 2013 and April 17, 2013, the Company sold Data Bus and Sensors and repaid approximately $28,780 and $44,919, respectively, of its term loans from the proceeds of these sales, in accordance with the Term Loan Agreement. In addition, the Company repaid a portion of its term loans using the net proceeds of $739 from the March 14, 2013, sale of certain land and a building in Palm Bay, Florida. On May 22, 2013, the Company entered into a First Amendment to the Revolving Loan Agreement that amends certain cash management and reporting requirements. On October 10, 2013, the Company entered into an Amendment No. 1 to the Credit Agreement (the "Amendment No. 1") by and among the Company, as borrower, the lenders party thereto and the Agent. Amendment No. 1, among other things, amends the Term Loan Agreement to reduce the minimum interest coverage ratio, increase the maximum leverage ratio, reduce the interest rate on the term loans and modify the terms of the prepayment premium, which the Company is required to pay upon voluntary prepayments or certain mandatory prepayments of the term loans. On March 21, 2014, the Company entered into Amendment No. 2 to the Credit Agreement (the "Amendment No. 2"), by and among the Company, as borrower, the lenders party thereto and the Agent. Amendment No. 2 amends the Term Loan Agreement to provide for an incremental term loan facility in an aggregate principal amount equal to $55,000 (the "Incremental Term Loan Facility"), which Incremental Term Loan Facility is subject to substantially the same terms and conditions, including the applicable interest rate and the maturity date of February 6, 2018, as the $165,000 term loan facility provided upon the initial closing of the Term Loan Agreement. In addition, Amendment No. 2 amends the Term Loan Agreement to reduce the minimum interest coverage ratio and increase the maximum leverage ratio, among other things. The proceeds of the Incremental Term Loan Facility were used (i) to pay in full and terminate the Company's Revolving Loan Agreement; (ii) to redeem all 26,000 shares of the Company's Series A Preferred Stock that were outstanding (as defined and described in Note 10); (iii) to pay fees, costs and expenses associated with the Incremental Term Loan Facility and related transactions; and (iv) for general corporate purposes. This resulted in the write-off of approximately $10,212 of deferred financing costs and note discounts in the quarter ended May 31, 2014. Term Loan Agreement The term loans incurred pursuant to the Term Loan Agreement, as amended, bear interest, at the Company's option, at the base rate plus 6.50% or an adjusted LIBOR rate (based on one, two or three-month interest periods) plus 7.50% for the first year and at the base rate plus 7.50% or an adjusted LIBOR rate (based on one, two or three-month interest periods) plus 10.75% thereafter, with a LIBOR floor of 1.50%. For purposes of the Term Loan Agreement, the "base rate" means the highest of Wells Fargo Bank, National Association's prime rate, the federal funds rate plus a margin equal to 0.50% and the adjusted LIBOR rate for a 3-month interest period plus a margin equal to 1.00%. Interest is due and payable in arrears monthly for term loans bearing interest at the base rate and at the end of an interest period (or at each three month interval in the case of term loans with interest periods greater than three months) in the case of term loans bearing interest at the adjusted LIBOR rate. Principal payments of the term loans are paid at the end of each of the Company's fiscal quarters, commencing for the fiscal quarter ending May 31, 2013, with the balance of any outstanding term loans due and payable in full on February 6, 2018. The quarterly principal payments will amortize at 1.25% for the fiscal quarters through the end of the Company's 2014 fiscal year, at 1.875% for the fiscal quarters through the end of the Company's 2015 fiscal year and at 2.50% for each of the fiscal quarters thereafter. Under certain circumstances, the Company is required to prepay the term loans upon the receipt of cash proceeds of certain asset sales, cash proceeds of certain extraordinary receipts and cash proceeds of certain debt or equity financings, and based on a calculation of annual excess cash flow. Mandatory prepayments resulting from assets sales or certain debt financings may require the payment of certain prepayment premiums. The term loans are secured by a first priority security interest in accounts receivable, inventory, machinery, equipment and certain other personal property relating to the foregoing, and any proceeds from any of the foregoing, subject to certain exceptions and liens, and a first priority security position on substantially all other real and personal property, in each case that are owned by the Company and the subsidiary guarantors. The Term Loan Agreement contains customary affirmative and negative covenants, including covenants that limit or restrict the Company and its subsidiaries' ability to, among other things, incur indebtedness, grant liens, dispose of assets and pay dividends or make distributions to stockholders, in each case subject to customary exceptions for a term loan of this size and type. Pursuant to the Term Loan Agreement, the Company is required to maintain compliance with an interest coverage ratio and a leverage ratio and to limit its annual capital expenditures to $4,000 per fiscal year (subject to carry-over rights). Revolving Loan Agreement On March 21, 2014, approximately $25,136 of the proceeds of the Incremental Term Loan Facility were used to pay in full and terminate the Company's Revolving Loan Agreement. The revolving loans incurred pursuant to the Revolving Loan Agreement bore interest, at the Company's option, at the base rate plus a margin between 1.50% and 2.00% or an adjusted LIBOR rate (based on one, two, three or six-month interest periods) plus a margin between 2.50% and 3.00%, in each case with such margin being determined based on the Company's average daily excess availability under the revolving credit facility for the preceding fiscal quarter. For purposes of the Revolving Loan Agreement, the "base rate" means the highest of Wells Fargo Bank, National Association's prime rate, the federal funds rate plus a margin equal to 0.50% and the adjusted LIBOR rate for a 3-month interest period plus a margin equal to 1.00%. Interest was due and payable in arrears monthly for revolving loans bearing interest at the base rate and at the end of an interest period (or at each three month interval in the case of loans with interest periods greater than three months) in the case of revolving loans bearing interest at the adjusted LIBOR rate. Principal, together with all accrued and unpaid interest, would have been due and payable on February 6, 2018. The Company was permitted to prepay the revolving loans and terminate the commitments, in whole or in part, at any time without premium or penalty. Under certain circumstances, the Company was required to prepay the revolving loans upon the receipt of cash proceeds of certain asset sales. All borrowings under the Revolving Loan Agreement were limited by amounts available pursuant to a borrowing base calculation, which was based on percentages of eligible accounts receivable, inventory, machinery and equipment, in each case subject to reductions for applicable reserves. The Revolving Loan Agreement contained customary affirmative and negative covenants, including covenants that limited or restricted the Company and its subsidiaries' ability to, among other things, incur indebtedness, grant liens, dispose of assets and pay dividends or make distributions to stockholders, in each case subject to customary exceptions for a credit facility of this size and type. Pursuant to the Revolving Loan Agreement, the Company was also required to maintain compliance with a fixed charge coverage ratio and to limit its annual capital expenditures to $4,000 per fiscal year (subject to carry-over rights) at such times that it failed to maintain excess availability under the revolving credit facility above a specified level.
