Item 1.01 Entry into a Material Definitive Agreement

On May 14, 2008, CETCO Oilfield Services Company (“COSCO”), a Delaware corporation and wholly-owned subsidiary of AMCOL International Corporation (the “Company”) entered into, an Asset Purchase Agreement (the “Purchase Agreement”) with Premium Reeled Tubing, L.L.C., a Louisiana limited liability company (“PRT”), pursuant to which COSCO purchased substantially all the assets, and assumed certain liabilities, of PRT related to or used in the oilfield service and coil tubing industries (the “Acquisition”). The aggregate purchase price was $44.2 million in cash and stock of the Company, and the Acquisition was completed with entry into the Purchase Agreement on May 14, 2008, effective as of 10:00 a.m., Central Time, on May 15, 2008. The foregoing does not purport to be a complete description of the Purchase Agreement and is qualified in its entirety by reference to the Purchase Agreement, a copy of which is attached hereto as Exhibit 10.1 and which is incorporated herein by reference to provide information regarding its terms.

The Purchase Agreement contains representations and warranties that should not be relied upon by investors as statements of factual information. Except for its status as the contractual document between the parties with respect to the transactions described therein, the Purchase Agreement is not intended to provide factual information about the parties. The representation and warranties were made only for purposes of the Purchase Agreement, as of specific dates, and were solely for the benefit of the parties to the Purchase Agreement, which may be subject to limitations agreed to by the parties, including being qualified by disclosures between the parties. These representations and warranties may also have been made for purposes of allocating contractual risk between the parties to the Purchase Agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the parties that differ from those applicable to investors.

Item 8.01Other Events

On May 19, 2008, the Company issued a press release announcing the Acquisition, which press release is attached hereto as Exhibit 99.1 and incorporated herein by reference.
