Item 1.01:          Entry into a Material Definitive Agreement

On April 19, 2013, we amended our senior credit facility pursuant to that certain Second Amendment to Credit & Guaranty Agreement by and among Vicar Operating, Inc., VCA Antech, Inc., certain subsidiaries of Vicar Operating, Inc. as guarantors, various lenders from time to time party thereto, and Wells Fargo Bank, N.A., as Administrative Agent, Collateral Agent, Issuing Bank and Swing Line Lender.   In this report we refer to the Second Amendment to Credit & Guaranty Agreement as the Second Amendment.

The Second Amendment (i) removes limits on our ability to conduct a share repurchase program so long as we remain in compliance with certain existing financial covenants; (ii) increases the income we may receive from leases and subleases; (iii) increases the amount of debt we may assume in connection with acquisitions; and (iv) increases our ability to invest in Canada and the United Kingdom.

A copy of the Second Amendment is attached to this Form 8-K as Exhibit 10.1.

On April 25, 2013, we issued a press release which included earnings for the first quarter of fiscal year 2013. A copy of the press release is furnished as Exhibit 99.1 to this Form 8-K.

Item 8.01:          Other Events.  

On April 25, 2013, we announced that our Board of Directors approved a share repurchase program authorizing us to repurchase up to $125 million of our common stock.  The repurchases, which may be made in the open market, through privately-negotiated transactions, or as otherwise permitted by Securities Exchange Act Rule 10b-18, may occur from time-to-time in the future.  We have no obligation to repurchase any shares, and we may suspend or discontinue the repurchase program at any time.  We may finance repurchases from existing cash balance or borrowings pursuant to our revolving credit facility.

A copy of the press release announcing the share repurchase program is attached hereto as Exhibit 99.1 and incorporated herein by reference.
