On May 24, 2011, Bruker Corporation (the “Company”) and certain of its foreign subsidiaries as borrowers entered into an amendment and restatement of the Credit Agreement, dated as of February 26, 2008, with JPMorgan Chase Bank, N.A., as Administrative Agent, and the other lenders parties thereto (the “Amended and Restated Credit Agreement”), to, among other things, extend the maturity date of and increase the amount available for borrowing under the revolving credit facility, release all collateral pledged to the lenders and modify certain covenants.

Pursuant to the Amended and Restated Credit Agreement, the maturity date of the revolving credit facility has been extended to May 24, 2016 and the available capacity under the revolving credit facility has been expanded to $250.0 million.  The Amended and Restated Credit Agreement also contains revised pricing terms for the revolving credit facility.  The Amended and Restated Credit Agreement continues the term loan facility which matures on February 26, 2013.  As of May 24, 2011, outstanding borrowings under the revolving credit facility totaled approximately $185.5 million and the outstanding principal amount under the term loan facility totaled $105.0 million. The obligations under the Amended and Restated Credit Agreement are unsecured and are fully and unconditionally guaranteed by the Company and each of its direct and indirect material subsidiaries.

The Amended and Restated Credit Agreement contains affirmative, negative and financial covenants customary for financings of this type. The negative covenants include, among others, restrictions on liens, indebtedness of the Company and its subsidiaries, asset sales, dividends, and transactions with affiliates. The financial covenants include total leverage and minimum interest coverage ratios of the Company.

The Amended and Restated Credit Agreement specifies customary events of default including, without limitation, payment defaults, defaults in the performance of affirmative and negative covenants, the inaccuracy of representations and warranties, bankruptcy and insolvency related events, certain ERISA events, material judgments, and a change of control default. The obligations of the Company and any additional subsidiary borrowers under the Amended and Restated Credit Agreement may be accelerated upon the occurrence of an event of default.

From time to time in the ordinary course of business, certain of the lenders or their affiliates have provided, and may in the future provide, investment banking, financial advisory, lending and/or commercial banking services for the Company and certain of its subsidiaries and affiliates.

The foregoing description of the Amended and Restated Credit Agreement is only a summary and is qualified in its entirety by reference to the full text of the Amended and Restated Credit Agreement, which is attached hereto as Exhibit 10.1.

The information set forth in Item 1.01 is incorporated by reference herein.

See Exhibit Index.
