December 26, 2002

Dear Osmonics Colleague:

GE announced on Friday, December 20, its intention to combine Osmonics, GE Water Technologies (GEWT) and GE Betz into a single, fully integrated business to serve water and industrial fluid process customers around the world, pending the closing of the GE/Osmonics merger which, assuming satisfaction of the closing conditions, is expected to close in the first quarter of 2003. I had an opportunity to meet with the leadership of GE Betz and GEWT last week to begin the integration planning process, and I believe that this move will be a great one for Osmonics employees and its customers.

As we said last month when we announced the merger of Osmonics with GE Power Systems, our business is destined to play a central role in the evolution and growth of GE's water and industrial fluid process technology enterprise, and that outlook hasn't changed. As a leader in our chosen markets and in advanced technologies associated with water purification and fluid filtration and handling, Osmonics brings significant complementary strengths to GE's emerging water business.

GE's decision to combine the three businesses into a single entity enhances our opportunity to make a contribution to the success of this growth platform, enables us to generate even greater value for our current customers, and positions us favorably to attract new customers. And it will enable GE to leverage technologies, expertise and best practices across its pursuits in water and industrial fluid processes in ways that reap big rewards for both the business and its customers.

The new integrated business will be led by George Oliver, currently vice president and general manager of GE Betz, and will be a unit within GE Specialty Materials, led by Bill Woodburn. Both George and Bill have great respect for the heritage and capabilities of Osmonics and are excited by the prospect of bringing together these three excellent businesses. Additionally, they are committed to having leaders from Osmonics, GEWT and GE Betz all play significant roles in the planning and execution of the integration activity.

You'll hear more about this important and very positive development as the closing of the merger nears. In the meantime, your support and effort continue to be very much appreciated.

Thank you and best regards,

Dean
