Long-Term Obligations

Senior Credit Facility

On January 25, 2012, we executed an amendment (the "first amendment") to our Amended and Restated Credit and Guaranty Agreement entered into as of August 16, 2011 (our "senior credit facility"). On January 24, 2012, we issued new term loans in the aggregate principal amount of $50.0 million, which reduced the amount of uncommitted incremental facilities we could thereafter elect to request from $100.0 million in the aggregate to $50.0 million in the aggregate. The aforementioned amendment on January 25, 2012 replenished the aggregate principal amount of uncommitted incremental facilities by $50.0 million to permit us to request up to an aggregate principal amount of $100.0 million in uncommitted incremental facilities. The funds borrowed from the Incremental Facility were used to repay in full amounts borrowed to fund an additional investment in Associate Veterinary Clinics (1981) LTD ("AVC") on February 1, 2012. In connection with the first amendment we incurred $122,300 in financing costs, of which approximately $47,300 were recognized as part of income from continuing operations and $75,000 were capitalized as deferred financing costs.

The following table summarizes our long-term obligations at June 30, 2012 and December 31, 2011 (in thousands):

Interest Rate. In general, borrowings under the senior term notes and the revolving credit facility bear interest, at our option, on either:


•	the base rate (as defined below) plus the applicable margin. The applicable margin for a base rate loan is an amount equal to the applicable margin for Eurodollar rate (as defined below) minus 1.00%; or


•	the adjusted Eurodollar rate (as defined below), plus a margin of 1.75% (Level II, see table below) per annum until the date of delivery of the compliance certificate and the financial statements for the period ended June 30, 2012, at which time the applicable margin will be determined by reference to the leverage ratio in effect from time to time as set forth in the following table:



Level	Leverage Ratio	Applicable Margin for Eurodollar Rate Loans	Applicable Revolving Commitment Fee %
I	≥ 2.50:1.00	2.25%	0.50%
II	< 2.50:1.00 and ≥ 1.75:1.00	1.75%	0.375%
III	< 1.75:1.00 and ≥ 1.00:1.00	1.50%	0.25%
IV	< 1.00:1.00	1.25%	0.20%

The base rate for the senior term notes is a rate per annum equal to the greatest of Wells Fargo Bank, N.A. ("Wells Fargo") prime rate in effect on such day, the Federal funds effective rate in effect on such day plus 0.5% and the adjusted Eurodollar rate for a one-month interest period commencing on such day plus 1.0%. The adjusted Eurodollar rate is defined as the rate per annum obtained by dividing (1) the rate of interest offered to Wells Fargo on the London interbank market by (2) a percentage equal to 100% minus the stated maximum rate of all reserve requirements applicable to any member bank of the Federal Reserve System in respect of “Eurocurrency liabilities.”
