4. Borrowing Arrangements

On July 3, 2012, in connection with the Company’s acquisition of AIT and the refinancing of its prior credit facility, the Company entered into a credit agreement (the “Credit Agreement”) by and among the Company, certain of its subsidiaries, Silicon Valley Bank, U.S. Bank National Association and HSBC Bank (collectively, the “Lenders”). The Credit Agreement provides for a term loan in an aggregate principal amount of $40.0 million (the “Term Loan”) and a revolving credit facility in an aggregate principal amount of $40.0 million (the “Revolving Credit Facility”), a letter of credit facility in the aggregate availability amount of $15.0 million (as a sublimit of such Revolving Credit Facility) (the “L/C Facility”) and a swing line sub-facility in the aggregate availability amount of $4.0 million (as a sublimit of the Revolving Credit Facility) (together with the Term Loan, the Revolving Credit Facility and the L/C Facility, the “Credit Facility”). On July 3, 2012, the Company borrowed an aggregate of $40.0 million under the Term Loan and approximately $39.8 million under the Revolving Credit Facility. The borrowed funds were used at the closing of the Company’s acquisition of AIT to finance the acquisition and repay the outstanding balance of $3.7 million to Silicon Valley Bank as lender under the Company’s prior credit facility. The prior credit facility was terminated in connection with this transaction.

The Credit Facility must be repaid in consecutive quarterly installments of $2.5 million, with the first payment made on September 30, 2012, and with the balance of the then-outstanding principal amount due at the final maturity, which is July 3, 2016. The Revolving Credit Facility is available for the four-year period beginning on July 3, 2012. The Credit Agreement includes customary representations, warranties, covenants and events of default. The Company and certain of its subsidiaries have agreed to secure all of their obligations under the Credit Agreement by granting a first priority lien in substantially all of their respective personal property assets of these entities (subject to certain exceptions and limitations).

At the Company’s option, borrowings under the Term Loan and Revolving Credit Facility (subject to certain limitations) bear interest at either a base rate or at the London Interbank Offered Rate (“LIBOR”) (with the LIBOR being adjusted for certain Eurocurrency reserve requirements, if any, as described in the Credit Agreement), plus, in each case, an applicable margin based on the Company’s consolidated leverage ratio. All loans described above made on July 3, 2012 were initially base rate loans, carrying interest of 3.75%. As of March 28, 2014, the interest rates on the Term Loan and Revolving Credit Facility were 3.67% and 3.75%, respectively. The effective interest rates will be slightly higher due to the incurrence of certain loan-related costs of approximately $1.9 million that are treated as deferred interest and amortized over the life of the loan.

The Credit Agreement requires the Company to maintain certain financial covenants including a minimum consolidated fixed charge coverage ratio, a maximum consolidated leverage ratio and minimum domestic cash balances. On February 15, 2013, the Company and the Lenders amended the Credit Agreement in order to modify the financial covenants contained in the Credit Agreement, effective January 30, 2013. The Credit Agreement, as amended, requires the Company to comply with the following financial covenants:

•

a minimum consolidated fixed charge coverage ratio (as defined in the Credit Agreement, as amended), measured over the preceding four fiscal quarters, beginning as of the end of the third quarter of fiscal 2014, of 1.10 to 1.00, stepping up to 1.25 to 1.00 as of the end of each fiscal quarter beginning with the first quarter of fiscal 2015 and thereafter;

•

a maximum consolidated leverage ratio (as defined in the Credit Agreement, as amended) measured over the preceding four fiscal quarters, beginning, as of the end of the third quarter of fiscal 2014, of 4.00 to 1.00, stepping down to 3.75 to 1.00 as of the end of the fourth quarter of fiscal 2014 and thereafter to and including the third quarter of 2015, and 3.25 to 1.00 as of the end of each fiscal quarter beginning with the fourth quarter of 2015 and thereafter;

•

minimum domestic cash of $15.0 million as of the last day of any fiscal quarter and $10.0 million as of the last day of any other fiscal month from January 25, 2013 and thereafter;

•

a minimum consolidated quick ratio (as defined in the Credit Agreement, as amended) of 1.10 to 1.00 as of the end of each fiscal month from January 25, 2013 and thereafter;

•

minimum consolidated adjusted EBITDA (as defined in the Credit Agreement, as amended), measured over the preceding two quarters, of $6.0 million as of the end of the fourth quarter of 2013, $7.0 million as of the end of the first quarter of 2014 and $8.0 million as of the end of the second quarter of 2014 and each quarter thereafter.

The Company was in compliance with all covenants for the quarter ended March 28, 2014.

The Credit Agreement contains provisions requiring the following mandatory prepayments (subject to certain exceptions and limitations): (i) prepayments equal to 50% of the net cash proceeds from the issuance of capital stock by the Company’s primary operating subsidiary (or any of its subsidiaries); (ii) prepayments equal to 100% of the net cash proceeds from the incurrence of any indebtedness by the Company’s primary operating subsidiary over $250,000; (iii) prepayments equal to the net cash proceeds from certain asset sales or insurance or condemnation recoveries; and (iv) annual prepayments in an amount equal to (a) 33% of excess cash flow (as defined in the Credit Agreement, as amended) if the aggregate outstanding principal amount of the Term Loan equals or exceeds $20.0 million and (b) 25% of excess cash flow if the aggregate outstanding principal amount of the Term Loan equals or exceeds $10.0 million but is less than $20.0 million.

The Credit Agreement also restricts the Company from declaring or paying any cash dividends.

As of March 28, 2014, the outstanding amounts under the Company’s Term Loan and Revolving Credit Facility were $25.0 million and $39.8 million, respectively, which are net of unamortized debt issuance costs of $1.1 million for a total debt balance of $63.7 million. The Company analyzed the Credit Agreement and determined that the outstanding balance of Revolving Credit Facility debt should be classified as short-term due to acceleration clauses in the agreement.
