On January 21, 2015, Fleetmatics Group PLC and its subsidiaries Fleetmatics USA, LLC and Fleetmatics Development Limited, as borrowers (the “Company”) have entered into a Credit Agreement with Citibank, N.A., as administrative agent, and the lenders party thereto, for a senior, first-priority secured financing comprised of revolving loans, letters of credit and swing line loans in a total maximum amount of $125,000,000 (the “Credit Facility’).

The Credit Facility consists of a five-year multi-currency revolving credit facility in a dollar amount of up to $125,000,000 which includes a sublimit of $5,000,000 million for letters of credit and a $10,000,000 million swing line facility. The Credit Facility also includes an accordion feature that will allow the Company to increase the Credit Facility by a total of up to $75,000,000, subject to securing additional commitments from existing lenders or new lending institutions. The Company will use the net proceeds of borrowings under the Credit Facility to repay the $23,750,000 outstanding under the Company’s previously existing revolving credit facility with Wells Fargo Capital Finance, LLC and for working capital and other general corporate purposes.

At the Company’s election, loans made under the Credit Facility bear interest at either (1) a rate per annum equal to (a) the highest of the Administrative Agent’s prime rate, or 0.5% in excess of the Federal Funds Effective Rate or 2.0% in excess of one-month LIBOR (the “Base Rate”), plus an applicable margin, or (2) the one-, two-, three-, or six-month per annum LIBOR for deposits in U.S. dollars, plus an applicable margin. The applicable margin for the revolving loans depends on the Company leverage ratio and varies from 0.5% to 1.25%, in the case of Base Rate loans, and from 1.50% to 2.25%, in the case of LIBOR loans. Swing line loans bear interest at the Base Rate.

Commitment fees on the average daily unused portion of the Credit Facility (excluding swing line loans) are payable at rates per annum ranging from 0.2% to 0.3%, depending the Company’s leverage ratio.

Borrowings under the Credit Facility are secured by the capital stock or other equity interests of the borrowers, (other than Fleetmatics Group PLC) and substantially all of Fleetmatics Group PLC’s material foreign and domestic subsidiaries and are guaranteed by substantially all of the borrowers’ existing subsidiaries and future material subsidiaries.

The Credit Facility contains certain customary financial, affirmative and negative covenants including a maximum leverage ratio and minimum interest coverage ratio and negative covenants that limit or restrict, among other things, dividends, secured indebtedness, mergers and fundamental changes, asset dispositions and sales, investments and acquisitions, liens and encumbrances, transactions with affiliates, and other matters customarily restricted in such agreements.

Amounts borrowed under the Credit Facility may be repaid and, subject to customary terms and conditions, reborrowed at any time during and up to the maturity date. Any outstanding balance under the Credit Facility is due and payable no later than January 21, 2020.

The foregoing description of the Credit Facility does not purport to be complete and is qualified in its entirety by reference to the credit agreement evidencing the Credit Facility, a copy of which is attached hereto as Exhibit 99.1 and is incorporated herein by this reference.
