On November 24, 2004, the Registrant issued the following press release:

                                  PRESS RELEASE

                    GENERAL ELECTRIC AGREES TO ACQUIRE IONICS

          Growing GE's World-Class Water & Process Treatment Platform;
    Expands Desalination, Water Reuse and Industrial Ultrapure Water Services

WILTON, CONNECTICUT (NOVEMBER 24, 2004) - GE Infrastructure, a unit of General
Electric Company (NYSE: GE), and Ionics, Inc. (NYSE: ION) announced today that
they have signed a definitive agreement to merge Ionics into GE in an all-cash
transaction. GE is offering to purchase Ionics for $44 per share, valuing the
transaction at approximately $1.1 billion plus the assumption of existing debt.
Ionics is a global leader in desalination, water reuse & recycling, and
industrial ultrapure water services. Ionics will join GE Infrastructure's Water
& Process Technologies business unit upon completion of the transaction.

"Water is the lifeblood of industries and communities around the world, and
scarcity, increasing demand and rising costs are driving the need to conserve,
reuse and identify new supplies of this essential resource," said Bill Woodburn,
President and CEO of GE Infrastructure. "The combination of Ionics' technology,
project experience, and services network with GE's operating and project finance
expertise will accelerate the development of technology solutions for the global
water purification segment. We see significant revenue and cost synergies that
will enable us to focus our resources on developing technologies that increase
access to safe drinking water and provide industrial customers with greater
access to ultrapure water sources."



Doug Brown, CEO of Ionics said, "Through this merger we create the opportunity
to serve our industrial and municipal customers in new and exciting ways. Both
GE and Ionics are focused on building the water services business. By combining
our technology with GE's and by accessing GE's financial strength and world
class international organization, we substantially enhance our ability to
deliver our water purification services globally."

George Oliver, GE Infrastructure's President of Water & Process Technologies
said, "This acquisition strengthens GE's commitment to people, technology and
solutions. There are great synergies between the two companies - GE currently
has more than 2,000 scientists and engineers focused on improving water quality
for industrial and commercial use, and the addition of Ionics expands our
ability to provide solutions to our customers' most pressing water needs. Ionics
has established technologies, engineering resources and global desalination
management capabilities that gives GE a significant presence in the potable
water segment.

"Because Ionics utilizes multiple technologies for its emergency mobile fleet,
we will be able to offer expanded services for our industrial customers who need
immediate assistance treating their water supply," Oliver said. "The acquisition
of Ionics reinforces our commitment to our customers by providing the services
they need to remain productive and profitable."

Additional Information about the Proposed Merger
- ------------------------------------------------
The merger is subject to the approval of the holders of at least two-thirds of
Ionics outstanding common shares, usual government approvals and other customary
conditions. It is expected to close in the first half of 2005. Certain Ionics
stockholders, representing approximately 20% of the outstanding Ionics common
stock, have agreed to vote their shares in favor of the transaction.

Ionics' stockholders will be able to obtain copies of these documents when they
become available together with other documents filed with the SEC, free of
charge, through the web site maintained by the SEC at http://www.sec.gov.
Stockholders can also obtain, free of charge, copies of the proxy statement when
it becomes available, together with any other documents Ionics has filed with
the SEC, by directing a request to Ionics Incorporated, 65 Grove Street,
Watertown, MA 02472, attention Investor Relations, telephone: (617) 926-2500

Ionics and its directors and executive officers may be deemed to be participants
in the solicitation of proxies from Ionics' stockholders in favor of the
adoption and approval of the merger agreement and approval of the transactions
contemplated thereby, including the merger. Investors and stockholders may
obtain additional information regarding the interest of the participants from
the proxy statement, which may be obtained as and when set forth above.

ATTACHED MEMORANDUM:

24 November 2004

To Ionics worldwide staff:

I am pleased to announce that Ionics has entered into an agreement to be
acquired by General Electric and to become part of GE Infrastructure's Water &
Process Technologies business unit. Under the terms of the proposed acquisition,
which is expected to close in the first quarter of 2005, Ionics shares will be
purchased by GE for $44.00 per share in cash. Additional details are supplied in
the attached press release.



Both Ionics and GE Water are leading companies in the water purification
industry. There should be significant opportunities to both grow revenue and
reduce costs by combining our two organizations. Ionics brings capabilities in
seawater desalination, plant operations, and mobile services which GE Water
would like to develop. GE Water brings significant strength with their membrane
manufacturing, international distribution and financial structuring capabilities
which will help us expand our business. Together, there are real opportunities
for synergies which will improve the products and services we can offer our
customers. Overall, the proposed transaction with GE will substantially enhance
our ability to deliver our water purification services globally.

I'm sure many of you have questions about how this transaction will affect you
and the company. I have attached a summary Q&A document to answer some of these
questions.

Since I joined the Company a year and a half ago, we have made tremendous
progress at transforming Ionics into a company which delivers profits
consistently. I appreciate everyone's commitment and effort as we restructured
our organization, acquired Ecolochem, implemented Oracle, developed standard
products and, in general, streamlined our activities. We have accomplished a lot
in a short period and should be proud of our efforts. I want to personally
express my appreciation for your support.

Sincerely,

Doug Brown
CEO

ATTACHED PROPOSED GE ACQUISITION OF IONICS FREQUENTLY ASKED QUESTIONS


                        PROPOSED GE ACQUISITION OF IONICS
                           FREQUENTLY ASKED QUESTIONS

1.   HOW WILL IONICS FIT INTO GE?

     Ionics will become part of GE Infrastructure's Water & Process Technologies
     business unit. GE Water is a $1.5 billion business built through
     acquisitions of Glegg, Betz-Dearborn and Osmonics. Including Ionics, GE
     Water becomes a $2+ billion business.

2.   HOW WILL THE TRANSACTION WORK?

     The merger agreement we signed with GE calls for Ionics to distribute a
     proxy statement to Ionics shareholders in which the transaction will be
     described in detail, following which Ionics will call a special meeting of
     shareholders to vote on the merger. This meeting is expected to occur in
     the first quarter of 2005. Provided all the conditions to the merger are
     met, including all required regulatory approvals and approval by
     shareholders who own at least two-thirds of our shares, Ionics will be
     acquired by GE, and each Ionics share will be purchased for $44.00 in cash
     promptly following the shareholder meeting.

     The exact date of the acquisition will depend on how quickly regulatory
     approvals can be obtained, all other conditions can be met, and how soon
     the shareholder meeting can take place.



3.   CAN I BUY IONICS OR GE STOCK?

     Certain identified executives who have been subject to trading restrictions
     historically will continue to be restricted. Other employees are free to
     trade in both GE and Ionics stock.

4.   HOW WILL MY OPTIONS BE TREATED?

     All options - both vested and unvested - will be cashed out at $44 per
     share less the option exercise price when the transaction closes.

5.   WHAT WILL HAPPEN TO MY SALARY AND BENEFITS?

     GE has committed to provide pay and benefits to Ionics employees
     substantially comparable in the aggregate to our current pay and benefits
     for at least one year following the closing of the transaction.

6.   HOW WILL THE DEAL AFFECT RETIREES?

     We do not expect any effect on retirees except for the appreciation of
     their Ionics shareholdings, should they have any.

7.   WHAT SYNERGY OPPORTUNITIES DOES GE SEE IN THE TRANSACTION?

     GE expects significant synergies between the two companies that will result
     in opportunities to increase revenues and reduce costs. No specific
     integration plan is currently in place. GE will be developing this plan
     with assistance from Ionics' management.

8.   WHAT SHOULD WE BE TELLING CUSTOMERS?

     We expect that by combining Ionics' and GE Water's capabilities we can
     substantially enhance the products and services we offer to our customers.
     With access to GE's financing capabilities and international distribution,
     we will be able to deliver more products more cost effectively to more
     customers around the world.

9.   WHEN WILL INTEGRATION START?

     There are provisions in the merger agreement concerning how we will operate
     the business until the transaction closes which we will communicate to you
     as appropriate. Overall, our plan is to conduct business as usual until the
     closing. The integration plan will start to be implemented after the
     acquisition is completed.

10.  WHY DID WE CHOOSE TO SELL TO GE?

     GE Water and Ionics are both strong players in the water treatment
     industry. Ionics brings strength in large projects, sea water desalination,
     zero/liquid discharge and build-own-and-operate projects. GE brings
     strength in financing and international reach. Working with GE Water
     represents the best opportunity to grow Ionics and create a strong future
     for the business and employees.



11.  WHAT DOES THIS MEAN FOR IONICS IN THE FUTURE?

     GE is the largest industrial company in the world. It is consistently rated
     as one of the best run companies in America. Being part of GE should be
     good for our employees, our customers and our future.
