[1] The Company entered into a Credit Agreement on June 22, 2011. On November 6, 2012, the Company entered into a second amendment to the Credit Agreement to add an additional term loan of $250 million and increase the borrowing limit on the revolving line of credit from $600 million to $850 million. The Company also revised the option to increase the facility from an additional $150 million to an additional $250 million. As amended, the Credit Agreement provides for a $550 million term loan facility and a $850 million revolving credit facility. The interest rates on the amended Credit Agreement did not change. The revolving line of credit contains a $20 million sublimit for letters of credit, a $20 million sublimit for swing line loans and a sublimit for multicurrency borrowings in Euros, Sterling and Japanese Yen. Proceeds from this new credit facility were used to retire the Company's indebtedness under its 2005 Credit Facility and CCS Credit Facility, as described below. On March 13, 2012, the Company entered into the first amendment to the Credit Agreement. This Amendment added two United Kingdom entities as designated borrowers and added a $110 million foreign currency swing line of credit sub facility under the existing revolver, which allows for alternate currency borrowing on the swing line. Interest ranges from the sum of the Base Rate plus 0.25% to 1.25% or the Eurodollar Rate plus 1.25% to 2.25%. The term note is payable in quarterly installments and is due on the last business day of each March, June, September, and December with the final principal payment due in June 2016. Borrowings on the revolving line of credit are repayable at our option of one, two, three or six months after borrowing, depending on the term of the borrowing on the facility. Borrowings on the foreign swing line of credit are due no later than ten business days after such loan is made. This facility is referred to as the Credit Facility. Principal payments of $11.3 million were made on the term loan during the nine months ended September 30, 2012.

[2] In connection with the Company's acquisition of a Russian fuel card company, there is a final payment of $11.3 million due on December 15, 2013. The Company also is party to another acquisition agreement that includes contingent earn-out payments of $5.1 million, which is payable in three installments in December 2012, November 2013 and May 2016.

[3] The Company is party to a receivables purchase agreement (Securitization Facility) that was amended and restated for the fourth time as of October 29, 2007 and which has been amended seven times since then to add or remove purchasers, extend the facility termination date and remove all financial covenants. The current purchase limit under the Securitization Facility is $500 million. The Securitization Facility was amended for the seventh time on February 6, 2012 to add a new purchaser and extend the facility termination date to February 4, 2013. There is a program fee equal to the Commercial Paper Rate of 0.27%, plus 0.75% as of September 30, 2012. The unused facility fee is payable at a rate of 0.35% per annum as of September 30, 2012. The Securitization Facility provides for certain termination events, which includes nonpayment, upon the occurrence of which the administrator may declare the facility termination date to have occurred, may exercise certain enforcement rights with respect to the receivables, and may appoint a successor servicer, among other things.
