Line of Credit

On December 19, 2011, we and one of our subsidiaries entered into an Amended and Restated Credit Agreement (the "Amended Credit Agreement") that replaced our existing Credit Agreement. The Amended Credit Agreement matures on December 19, 2016 and provides for borrowings in an amount of up to $250.0 million with a sublimit for swing line loans of up to $10.0 million and standby letters of credit in a face amount of up to $50.0 million. TIBCO has an option to request that the lenders increase the available commitments by an amount of up to $100.0 million.

Revolving loans accrue interest at a per annum rate based on, at our option, either (i) the base rate plus a margin ranging from 0.25% to 1.00%, depending on TIBCO's consolidated leverage ratio or (ii) the LIBOR rate plus a margin ranging from 1.25% to 2.00%, depending on TIBCO's consolidated leverage ratio, for various interest periods. The base rate is defined as the highest of (i) the administrative agent's prime rate (ii) the federal funds rate plus a margin equal to 0.50%, and (iii) the LIBOR rate for a one month interest period plus a margin equal to 1.00%.

Loan origination fees and issuance costs of approximately $2.0 million were incurred upon consummation of the Amended Credit Agreement which will be amortized through interest expense over a period of five years.

Under the Amended Credit Agreement, we must maintain a minimum consolidated interest coverage ratio of 3.5:1.0 and a maximum consolidated leverage ratio of 2.5:1.0 in addition to other customary affirmative and negative covenants.
