Item 1.01. Entry into a Material Definitive Agreement.

On November 15, 2012, Ecolab Inc. (“Ecolab”) entered into a $900 million unsecured term loan credit agreement that matures three years after the loan funding date, among the lenders party thereto, Bank of America, N.A., as administrative agent and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as sole lead arranger (the “Term Loan Agreement”).

The Term Loan Agreement will be used to fund the previously announced merger between Permian Mud Service, Inc. (parent company of Champion Technologies, Inc. and Corsicana Technologies, Inc.) and OFC Technologies Corp., a wholly-owned subsidiary of Ecolab, which subject to standard closing conditions, including the receipt of required regulatory approvals, is expected to close prior to year end.

Borrowings under the Term Loan Agreement bear interest, at Ecolab’s option, at (i) the base rate (which is equal to the highest of (a) the Bank of America, N.A. prime rate, (b) the federal funds rate plus 0.50% and (c) one-month LIBOR plus 1.0%) plus an applicable margin or (ii) LIBOR plus an applicable margin.

In connection with the Term Loan Agreement, Ecolab must pay a commitment fee at a rate per annum which may range from 0.06% to 0.225% of the actual daily commitment of each lender from the date that the Term Loan Agreement is executed until the date that the term loan is funded or the commitment otherwise terminates.  The applicable rate for this fee will be determined based on Ecolab’s credit rating, as described in the Term Loan Agreement.

The Term Loan Agreement contains a financial covenant that requires Ecolab to maintain a minimum interest expense coverage ratio.  The Term Loan Agreement also contains customary conditions to funding, events of default, affirmative covenants and negative covenants, including restrictions on liens and subsidiary indebtedness.

In the ordinary course of their respective businesses, one or more of the lenders under the Term Loan Agreement, or their affiliates, have or may have various relationships with Ecolab and its subsidiaries involving the provision of financial services, including cash management, investment banking and trust services, for which they received, or will receive, customary fees and expenses.

The foregoing description is not intended to be complete and is qualified in its entirety by reference to the full text of the Term Loan Agreement, which is incorporated herein by reference and attached as Exhibit 10.1 hereto.
