Share Purchase Agreement

On May 11, 2013, KVH Industries UK Limited (“KVH UK”), a newly formed, wholly owned subsidiary of KVH Industries, Inc. (the “Company”), entered into a Share Purchase Agreement with Oakley Capital Private Equity L.P., Mark Woodhead, Andrew Michael Galvin and the Trustees of the Headland Media Limited Employee Benefit Trust to acquire all of the issued share capital of Headland Media Limited (“Headland”), a media and entertainment service company based in the United Kingdom that distributes premium news, sports, movies and music content for commercial and leisure customers in the maritime, hotel, and retail markets, for an aggregate purchase price of approximately $24 million. The acquisition was consummated on the same day. The purchase price was determined as a result of arms-length negotiation and is subject to a potential post-closing adjustment based on the value of the net assets delivered at the closing.

The Share Purchase Agreement contains certain representations, warranties, covenants and indemnification provisions. The Share Purchase Agreement provides that 10% of the purchase price shall be held in escrow for a period of at least 18 months after the closing in order to satisfy valid indemnification claims that the Company may assert for specified breaches of representations, warranties and covenants.

Credit Agreement Amendment and Note

On May 9, 2013, the Company and Bank of America, N.A. (the “Lender”) entered into the Eighth Amendment (the “Amendment”) to the Amended and Restated Credit and Security Agreement, dated July 17, 2003 (as amended to date, the “Credit Agreement”), which, among other modifications, increased the Company’s line of credit from $15.0 million to $30.0 million (the “Line”). As further evidence of the Line, the Company executed and delivered to the Lender an Amended and Restated Revolving Credit Note dated May 9, 2013 in the amount of up to $30.0 million (the “Note”). The Note matures on December 31, 2014. As additional security for the obligations of the Company to the Lender under the Credit Agreement and the Note, the Company pledged to the Lender 65% of the Company’s equity interest in KVH UK.

As amended, the Credit Agreement no longer permits the Company to convert revolving loans into term loans.

In connection with the acquisition of the outstanding shares of Headland pursuant to the Share Purchase Agreement, on May 9, 2013, the Company borrowed approximately $23 million to pay substantially all of the purchase price for the acquired shares. The entire principal balance of the loan is due and payable on December 31, 2014 and, based on rates in effect on the date hereof, the Company expects to make monthly interest payments of approximately $28,000 with respect to the loan, which interest payments will be subject to adjustment in accordance with the terms of the Credit Agreement. The Company’s obligation to repay the loan could be accelerated upon a default or event of default under the terms of the Credit Agreement, including certain failures to pay principal or interest when due, certain breaches of representations and warranties, the failure to comply with the Company’s affirmative and negative covenants under the Credit Agreement, a change of control of the Company, certain defaults in payment relating to other indebtedness, the acceleration of payment of certain other indebtedness, certain events relating to the liquidation, dissolution, bankruptcy, insolvency or receivership of the Company, the entry of certain judgments against the Company, certain events relating to the impairment of collateral or the Lender’s security interest therein, and any other material adverse change with respect to the Company.
