On August 2, 2013, the Company entered into a $50.0 million, three-year revolving credit facility, as described below (the “Credit Agreement”). The Credit Agreement replaced a predecessor revolving credit facility with First Victoria National Bank. The Credit Agreement is a three-year, secured revolving facility in the maximum principal amount of $50.0 million, among the Company, as borrower, HSBC Bank USA, N.A., as administrative agent and several banks and other financial institutions from time to time as lenders thereunder (initially consisting of HSBC Bank USA, N.A. and First Victoria National Bank).

Amounts available for borrowing under the Credit Agreement are determined by a borrowing base. The borrowing base is determined primarily based upon the appraised value of the Company’s domestic lease pool equipment and certain accounts receivable. The Credit Agreement is collateralized by essentially all of the Company’s domestic assets (other than real estate) and 65% of the capital stock of Mitcham Holdings, Ltd., a foreign holding company that holds the capital stock of the Company’s foreign subsidiaries.

The Credit Agreement provides interest at a base rate, or for Eurodollar borrowings, in both cases plus an applicable margin. As of January 31, 2015, the base rate margin was 175 basis points and the Eurodollar margin was 275 basis points. The Company has agreed to pay a commitment fee on the unused portion of the Credit Agreement of 0.375% to 0.5%. Up to $10.0 million of available borrowings under the Credit Agreement may be utilized to secure letters of credit. The Credit Agreement contains certain financial covenants that require, among other things, that the Company maintain a leverage ratio, which is calculated at the end of each quarter, of no greater than 2.00 to 1.00 on a trailing four quarter basis and a fixed charge coverage ratio, which also is calculated at the end of each quarter, of no less than 1.25 to 1.00 on a trailing four quarter basis. In addition, should Adjusted EBITDA, as defined in the Credit Agreement, for any trailing four quarter period be less than $22.0 million, the ratio of capital expenditures to Adjusted EBITDA for that four quarter period may not be greater than 1.0 to 1.0. The Credit Agreement also includes restrictions on additional indebtedness in excess of $5.0 million. The Company was in compliance with each of these provisions as of and for the fiscal year ended January 31, 2015.

The Credit Agreement contains customary representations, warranties, conditions precedent to credit extensions, affirmative and negative covenants and events of default. The negative covenants include restrictions on liens, additional indebtedness in excess of $5.0 million, acquisitions, fundamental changes, dispositions of property, restricted payments, and transactions with affiliates and lines of business. The events of default include a change in control provision.

On August 22, 2014, Seamap Singapore, entered into a $15.0 million credit facility (the “Seamap Credit Facility”) with The Hongkong and Shanghai Banking Corporation Limited (“HSBC-Singapore”). The facility consists of a $10.0 million term loan, a $3.0 million revolving credit facility, and a $2.0 million banker’s guarantee facility.

The term loan portion of the Seamap Credit Facility provides for eleven quarterly principal payments of $800,000 and a final payment of the remaining $1.2 million on or before August 22, 2017. Interest on the term facility is payable quarterly at LIBOR plus 2.75%. Under the Seamap Credit Facility, Seamap Singapore may borrow up to $3.0 million for a period of one to three months to be utilized for working capital and other general corporate purposes. Borrowings under the revolving credit facility bear interest at LIBOR plus 3.00%. Borrowings under this arrangement are secured by essentially all of the assets of Seamap Pte Ltd. and the Company’s guarantee.

The Seamap Credit Facility contains financial covenants that require Seamap Singapore to maintain a minimum shareholder’s equity of S$15 million and a minimum ratio of debt to EBITDA of not less than 125% for each fiscal year. The Company was in compliance with each of these provisions as of and for the fiscal year ended January 31, 2015.

The Seamap Credit Facility contains customary representations and warranties, conditions precedent to credit extensions, affirmative and negative covenants and events of default. The negative covenants include restrictions on liens, additional indebtedness, acquisitions, fundamental changes, dispositions of property, restricted payments, and transactions with affiliates. The Seamap Credit Facility also requires the Company, as guarantor, to comply with financial covenants contained in the Credit Agreement.

The Company’s average borrowings under the Credit Agreement, the predecessor revolving credit facility and the Seamap Credit Facility for the fiscal year ended January 31, 2015 and 2014 were approximately $26.3 million and $5.0 million, respectively.

From time to time, certain subsidiaries have entered into notes payable to finance the purchase of certain equipment, which are pledged as security for the notes payable.
