Amended and Restated Credit Agreement (Credit Agreement)

In June 2010, Bio-Rad entered into a $200.0 million Credit Agreement.

We had no outstanding borrowings under the Credit Agreement as of December 31, 2011. The Credit Agreement expires on June 21, 2014.

The Credit Agreement is secured by substantially all of our personal property assets, the assets of our domestic subsidiaries and 65% of the capital stock of certain of our foreign subsidiaries. It is guaranteed by all of our existing and future material domestic subsidiaries. The Credit Agreement and the 8.0% Notes require Bio-Rad to comply with certain financial ratios and covenants, among other things. These ratios and covenants include a leverage ratio test and an interest coverage test, as well as restrictions on our ability to declare or pay dividends, incur debt, guarantee debt, enter into transactions with affiliates, merge or consolidate, sell assets, make investments, create liens and prepay subordinated debt. We were in compliance with all of these ratios and covenants as of December 31, 2011.
