Credit Agreement

The Company’s existing Credit Agreement with Sovereign Bank (the “Credit Agreement”) includes a term loan feature and a revolving loan feature, and also allows for the issuance of letters of credit and other promissory notes. The Company can borrow up to a maximum of $20.0 million pursuant to the Credit Agreement, subject to the terms and limitations discussed below.

The Company has one outstanding note payable at June 30, 2016 under the term loan feature of the Credit Agreement with a principal amount of $1,714,000 (the “Term Loan”). In addition, the Company has two outstanding notes payable under the Credit Agreement that are not under the term loan feature (and therefore, do not count towards the maximum amounts that we may borrow) which were incurred to purchase (and are secured by) equipment, representing a remaining aggregate principal amount of $3,439,000 as of June 30, 2016. In addition, the Credit Agreement permits the Company to borrow, repay and re-borrow, from time to time until June 30, 2017, up to the lesser of $20.0 million or 80% of the Company’s eligible accounts receivable less the then-outstanding principal balance of the Term Loan (the “Line of Credit”). The Company has not utilized the Line of Credit during the current year. Because the Company’s ability to borrow funds under the Line of Credit is tied to the amount of the Company’s eligible accounts receivable, if the Company’s accounts receivable decrease materially for any reason, including delays, reductions or cancellations by clients or decreased demand for our services, our ability to borrow to fund operations or other obligations may be limited.

Sovereign Bank has also issued a letter of credit under the Credit Agreement in the principal amount of $1,767,000 in favor of AIG Assurance Company in order to support payment of certain insurance premiums of the Company. The principal amount of this letter of credit counts as funds borrowed under our Line of Credit.

The Company’s obligations under the Line of Credit are secured by a security interest in the Company’s accounts receivable, and the term notes are secured by certain of the Company’s core equipment. Interest on amounts outstanding under the Credit Agreement accrues at the lesser of 4.5% or the prime rate (as quoted in the Wall Street Journal), subject to an interest rate floor of 2.5%. The Credit Agreement contains customary covenants for credit facilities of this type, including limitations on disposition of assets, mergers and other fundamental changes. The Company is also obligated to meet certain financial covenants, including (i) a ratio of (x) total liabilities minus subordinated debt to (y) tangible net worth plus subordinated debt not to exceed 1.00:1.00, (ii) a ratio of current assets to current liabilities of at least 1.50:1.00 and (iii) required tangible net worth of not less than $150,000,000. The Company was in compliance with all covenants under the Credit Agreement, including specified ratios, as of June 30, 2016.
