Subject: Robbins & Myers to Merge with National Oilwell Varco

Earlier today we issued the attached press release detailing a merger agreement between Robbins & Myers and National Oilwell Varco (NOV). Under the terms of the agreement NOV will acquire all shares of Robbins & Myers. There are closing conditions, including regulatory approval, so we anticipate the final closing will take place sometime in the last quarter of this calendar year.

Those of you in the Energy Services Group will know National Oilwell Varco as an industry leader with a complete suite of products for oil and gas drilling and production operations. Our power sections, downhole pumps, pressure control products, and valve systems will complement NOV’s current product offering serving upstream oil and gas markets.

In addition to being a major player in the energy sector, National Oilwell Varco has a number of products and solutions serving industrial markets. Some of these products include multi-purpose pumps, solids shakers, motors, protective lining products and piping. There should be opportunities to leverage our Process and Flow Control product lines with the NOV offering to offer a more complete solution to certain customers in both industrial and energy markets.

Over the last number of years we have made tremendous strides in our business. Our success is due to each of you who come to work every day with a sense of purpose and a passion for your work, always putting the customers top of mind. Our plans to profitably grow the enterprise will take place quicker as we merge with National Oilwell Varco. I think you will find that Robbins & Myers and National Oilwell Varco share a common goal of working closely with customers in demanding applications to improve productivity, and ultimately their profitability.

National Oilwell Varco is headquartered in Houston, Texas. With annual sales approaching $20 billion, and a market cap in excess of $32 billion, we will be joining forces with a very strong company. NOV has cash on hand and a very small amount of debt, so they are capable of continuing to grow organically and through acquisition.

I am sure many of you will have questions as to how this merger may impact you. Between now and closing we will hold a number of meetings to address your questions. For the time being nothing changes; —our focus continues to be serving our customers.

Best regards,

Peter Wallace
