Ecolab Inc. announced it has agreed to purchase Microtek Medical Holdings Inc. (Nasdaq:MTMD), an Alpharetta, Georgia-based manufacturer and marketer of infection control products for healthcare and acute care facilities. Microtek’s specialized product lines include infection barrier equipment drapes, patient drapes, fluid control products and operating room cleanup systems. Microtek’s 2006 sales were $142 million.

Ecolab has agreed to pay $6.30 per share in cash for Microtek’s shares; Microtek had 43.5 million shares outstanding at June 30, 2007. The agreement has been approved by the boards of directors of both companies, and is subject to the approval of Microtek’s shareholders and other customary closing conditions, including regulatory approvals. Materials will be mailed to Microtek shareholders after required filings have been made with the Securities and Exchange Commission. Closing is expected to occur in the fourth quarter.

Douglas M. Baker, Jr., Ecolab’s Chairman, President and Chief Executive Officer commented on the announcement, saying, “This represents another strong step to significantly expand Ecolab’s growing presence in healthcare cleaning and infection prevention. As the global leader in premium cleaning and sanitation, we have a long-standing record of bringing new, innovative and effective solutions to the foodservice, lodging, food and beverage processing and healthcare industries, helping them to deliver cleaner, safer and healthier products, experiences and outcomes. We are continuing to build on our capabilities, particularly in the healthcare market, as we focus on improving cleaning and sanitizing solutions for patients and staff, and simultaneously reduce healthcare associated infections (HAIs).

“Microtek will combine with our existing hand hygiene, medical instrument, and surface and environmental cleaning and disinfection offerings to comprise a critical part of our strategy to offer broad and complete product solutions for the healthcare market, and especially HAIs,” Baker continued. “Further, Microtek’s strong team and excellent customer relationships will provide us new avenues to pursue future growth with our existing products.

“We expect dilution from the transaction to be approximately $0.01 per share in the fourth quarter 2007, but we believe our current business momentum will enable us to offset that; as a result, we continue to look for 2007 earnings per share to be in the $1.64 to $1.66 range. We expect dilution from Microtek to represent approximately $0.02 per share in 2008, and show accretion building thereafter.

Baker concluded by saying, “We see exciting potential for the combined operations of our companies and for the improved solutions we will bring to our customers and patients, as well as additional opportunities for both companies’ employees. We look forward to completing the transaction and joining our two great companies together in developing new and complete solutions for critical healthcare needs.”
