Strong Market Positions, Broad Product Portfolio and Leading Brands.    We believe that we are a leading manufacturer of rotary positive displacement pumps, which include screw pumps, gear pumps and progressive cavity pumps. We offer a broad portfolio of fluid handling products that fulfill critical needs of customers across numerous industries. Our brands are among the oldest and most recognized in the markets in which we participate.

Strong Application Expertise.    We believe that our reputation for quality and technical expertise positions us as a premium supplier of fluid handling products. With over 140 years of experience, we have significant expertise in designing and manufacturing fluid handling products that are used in critical applications, such as lubricating power generation turbines, transporting crude oil through pipelines and transferring heavy fuel oil in commercial marine vessels.

Extensive Global Sales, Distribution and Manufacturing Network.    We sell our products through over 300 direct sales and marketing associates and more than 450 authorized distributors in 79 countries. We believe that our global reach within the highly fragmented, worldwide fluid handling industry provides us with an ability to better serve our customers. Our European, North American and Asian manufacturing capabilities provide us with the ability to optimize material sourcing, transportation and production costs and lower foreign currency risk.

We Use CBS to Continuously Improve Our Business.    CBS is our business system designed to encourage a culture of continuous improvement in all aspects of our operations and strategic planning. Modeled on the Danaher Business System, CBS focuses on conducting root-cause analysis, developing process improvements and implementing sustainable systems. Our approach addresses the entire business, not just manufacturing operations.

Large Installed Base Generating Aftermarket Sales and Service.    With a product history dating back to 1860, we have a significant installed base across numerous industries. Because of the critical applications in which our products are used and the high quality and reliability of our products, we believe there is a tendency for our customers to replace “like for like” products. This tendency leads to significant aftermarket demand for replacement products as well as spare parts and for repair and maintenance service. In the year ended December 31, 2007, we estimate that approximately 25% of our revenues were derived from aftermarket sales and services.

Broad and Diverse Customer Base.    Our customer base spans numerous industries and is geographically diverse. Approximately 66% of our sales in 2007 were derived from operations outside of the U.S. In addition, no single customer represented more than 3% of our sales during that period.

Management Team with Extensive Industry Experience and Focus on Strategic Development.    We are led by a senior management team with an average of over 20 years of experience in industrial manufacturing. John A. Young, our President and Chief Executive Officer, is one of our founders and played a key role in developing the acquisition strategy that formed our company. Since 1995, as part of this strategy, we have acquired 12 companies and divested businesses that do not fit within our long-term growth strategy.

Apply CBS to Drive Profitable Sales Growth and Increase Shareholder Value.    The core element of our management philosophy is CBS, which we implement in each of our businesses. CBS is a strategic planning and execution methodology designed to achieve world-class excellence in all aspects of our business. CBS focuses our organization on continuous improvement and performance goals by empowering our associates to develop innovative strategies to meet customer needs. Rather than a static process, CBS continues to evolve as we benchmark ourselves against best-in-class industrial companies.

Execute Market Focused Strategies.    We believe that our five strategic markets are attractive due to their ongoing capital expenditure requirements, growth rates and global nature.

Commercial Marine—We intend to continue to increase our installed base of products and grow our aftermarket sales and service revenues. We also intend to expand our capabilities in the Asia Pacific region by utilizing our Chinese and Indian facilities to offer locally manufactured products, reduce production costs and provide local customer service and support.

Oil and Gas—We intend to continue our strategy of offering oil and gas customers increased efficiency and lower total cost of ownership by replacing legacy products currently in use with our more efficient products. We also intend to capture the growing need for complex turnkey systems through the development of solutions that can undertake the difficult task of handling varying mixtures of heavy crude oil, natural gas and water at the same time. We intend to continue to target the fast growing oil and gas markets around the world, including Asia and developing nations.

Power Generation—We intend to use our extensive expertise in power generation applications to continue our growth as a provider of turnkey systems in this market. We also intend to use our global presence to strengthen relationships with large original equipment manufacturers.

Global Navy—We intend to continue to design, develop and manufacture high value fluid handling systems to meet the needs of evolving naval requirements worldwide. For example, we are currently working with the U.S. Navy to incorporate advanced electronics and controls into our products, and we are also focused on expanding our repair and service capabilities for naval customers.

General Industrial—We intend to continue to apply our application expertise to supply our customers in diverse industries such as chemicals, pulp and paper processing and commercial construction with a portfolio of products that can solve their most critical fluid handling needs. We also intend to grow our presence in the general industrial market by targeting new applications for our existing products, deploying regionally focused strategies and utilizing our global presence and sales channels to sell our solutions worldwide.

Target Fast Growing Regions by Leveraging Our Global Manufacturing, Sales and Distribution Network.    We intend to continue to utilize our strong global presence and worldwide network of distributors to capitalize on growth opportunities by selling regionally developed and marketed products and solutions throughout the world. As our customers have become increasingly global in scope, we have increased our global reach to serve our customers by maintaining a local presence in numerous markets and investing in sales and marketing capabilities worldwide. For example, we have recently expanded our manufacturing capabilities by establishing a plant in China and acquiring an Indian manufacturer of fluid handling products.

Develop New Products, Applications and Technologies.    We will continue to engineer our key products to meet the needs of new and existing customers and also to improve our existing product offerings to strengthen our market position. We intend to develop technological, or “SMART,” solutions, which incorporate advanced electronics, sensors and controls, through the use of our Voice of the Customer process to solve specific customer needs. We believe our SMART solutions will reduce our customers’ total cost of ownership by providing real-time diagnostic capabilities to minimize downtime, increase operational efficiency and avoid unnecessary costs.

Grow Our Offerings of Systems and Solutions.    We will continue to provide high value added fluid handling solutions by utilizing our engineering and application expertise and our brand recognition and sales channels to drive incremental revenue. We intend to establish regional system manufacturing capabilities to address our customers’ desire to purchase turnkey modules and their preference for outsourced assembly. Part of our strategy is to continue to seek a greater share of overall project value by providing complete systems and solutions, particularly where we control project design.

Continue to Pursue Strategic Acquisitions that Complement Our Platform.    We believe that the fragmented nature of the fluid handling industry presents substantial consolidation and growth opportunities for companies with access to capital and the management expertise to execute a disciplined acquisition and integration program. We believe that we can identify a number of attractive acquisition candidates in the future and that strategic acquisition growth will give us a competitive advantage over small competitors through greater purchasing power, a larger global sales and distribution network and a broader portfolio of products and services.
