Dear                                         :

GE is announcing today its intention to integrate three separate entities into a single customer-focused business that will better serve GE's water and industrial process customers. This step is a great move for us all because it provides GE with enhanced opportunities to create increasingly greater value for our customers, and it represents the next logical step in the evolution and growth of our water and process technology business. And, in fact, this move took into account the feedback many of you have given me over the past few months.

Pending the closing of the Osmonics, Inc. acquisition, which assuming satisfaction of the closing conditions is expected to close in the first quarter of 2003, we plan to combine GE Betz, Osmonics, and GE Water Technologies (GEWT), presently a unit within GE Power Systems, into a single, integrated, customer-focused global business. I will have the privilege of leading this newly formed business, which will be a unit within GE Specialty Materials.

We are announcing this prospective action today so that we can begin immediately to formulate plans for the smooth integration of the three businesses. We want the new business to continue to provide the superior level of service our customers have come to expect, and we are committed to making sure the integration process is a seamless one for everyone we serve.

The newly-created business would make the most of synergy opportunities to broaden our portfolio of products and services for customers worldwide, so for our customers, the benefits of this planned integration are tremendous. You can anticipate access to more innovative technologies, more specialists, more field services, and to an even greater arsenal of water and process solutions to help you succeed.

We will update you on our progress as the new business comes together in 2003. In the meantime, thank you for your support as a valued customer, and be assured that our commitment to your success is stronger than ever.

George R. Oliver
Vice President & General Manager
GE Betz

On December 20, 2002, General Electric Company distributed the following letter to certain personnel of GE Betz:

Dear GE Betz Colleague:

It is a great day for GE Betz! GE Betz will soon be joined by GE Water Technologies and Osmonics, a planned acquisition, to form an integrated GE water and industrial process platform.

The blending of these three businesses creates an incredible mix of service, quality and products to serve thousands of water and industrial process customers across the globe.

We intend to combine GE Betz, GE Water Technologies, presently a unit within GE Power Systems, and Osmonics, Inc. a planned acquisition, which assuming satisfaction of the closing conditions is expected to close in the first quarter of 2003, into a single, integrated, customer-focused global business. I will have the privilege of leading this newly formed business, which will be a unit within GE Specialty Materials. The combined business will become official after the closing of the Osmonics acquisition.

GE Specialty Materials CEO Bill Woodburn and I wanted to be the first to share this exciting news with you. We will now begin to formulate plans for the smooth integration of the three businesses. We want the new business to present a single face to our water and process customers from the moment Osmonics joins GE, and we need to initiate a rigorous planning process now to make that happen.

There are many open issues and questions to be addressed in the integration process, but some aspects our new business should be self-evident. At the outset, we will be a powerful provider of products and solutions to a wide range of customers, with some 5,400 employees and approximately $1.4 billion in annual revenues. And we intend to grow this business rapidly, taking full advantage of the solid market positions, complementary capabilities, and technological strengths GE Betz, Osmonics, and GEWT all bring to this enterprise. We will make the most of synergy opportunities to broaden our portfolio of products and services for customers worldwide.

Our vision for the business structure will be focused upon product organizations that provide the highest quality products to an integrated commercial force that, in turn, delivers them efficiently to the marketplace. We fully expect that existing sales forces and distribution networks of the three businesses will be the keys to providing these products and services to current and new customers. As usual, we will continue to leverage technology, expertise and best practices from other parts of GE for the benefit of our water and process business customers.

I am committed to keeping you informed of our progress as we plan for this new business entity, and I am excited by the prospect of a great future for the business. I'm counting on the energy and effort of the entire GE Betz team to help us secure that future.

Sincerely,

/s/ George R. Oliver

On December 20, 2002, General Electric Company distributed the following e-mail to certain personnel of GE Specialty Materials:

December 20, 2002

Dear GESM Colleague:

As we get ready to wrap up 2002, I have some exciting news to share with all of you. GE Chairman, Jeff Immelt has approved the creation of an integrated GE water and industrial process platform within GE Specialty Materials. The business will combine GE Betz, GE Water Technologies (currently a part of the GE Power Systems portfolio) and Osmonics, a recently announced acquisition which, assuming satisfaction of the closing conditions, is expected to close in the first quarter of 2003. George Oliver will lead this combined business that will remain a part of the GE Specialty Materials portfolio.

The move further validates the strategic direction of GE Specialty Materials as a growth platform. The global industrial water and process market is a $110 billion global opportunity with boundless service and technology possibilities. The combination of GE Betz, GE Water Technologies and the planned Osmonics acquisition is something customers have been asking for—- an integrated commercial approach to their water and process needs.

George and his new combined team will now begin the process of meshing their organizations and working toward the successful closing and integration of Osmonics.

As in any integration, there are still many unanswered questions. We are working on the details of this strategic move and will communicate more when appropriate. I hope you are as energized by this news as I am.

        I would also like to take this opportunity to wish you and your families a joyous holiday season and a happy and healthy new year. Thanks for your continued support of our strategy and for all you do to keep GE Specialty Materials growing.

Bill
