Dear Stockholder:

      You are cordially invited to attend a Special Meeting of Stockholders of Ionics, Incorporated. The meeting is scheduled for February 22, 2005 at 1:00 P.M., EST, and will be held at Ionics’ principal offices, 65 Grove Street, Watertown, Massachusetts 02472-2882.

      At the meeting, you will be asked to approve the Merger Agreement that we entered into on November 24, 2004 with General Electric Company and Triton Acquisition Corp., an indirect wholly-owned subsidiary of GE. As a result of the Merger, Ionics will become an indirect wholly-owned subsidiary of GE. At the meeting you will also be asked to grant the persons named as proxies discretionary authority to vote to adjourn the Special Meeting, if necessary, to satisfy the conditions to completing the Merger as set forth in the Merger Agreement, including for the purpose of soliciting proxies to vote in favor of approving the Merger Agreement.

      If the Merger is completed, you will be entitled to receive $44.00 in cash, without interest, for each share of Ionics common stock that you own and you will have no ongoing ownership interest in the continuing business of Ionics. We cannot complete the Merger unless all of the conditions to closing are satisfied or waived, including the approval of the Merger Agreement by holders of at least two-thirds of the outstanding shares of Ionics common stock.

      Our board of directors carefully reviewed and considered the terms and conditions of the proposed Merger. Based on its review, the board of directors has determined that the terms of the Merger Agreement and the Merger are advisable and are in the best interests of Ionics and its stockholders.

      IONICS’ BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR THE PROPOSAL TO APPROVE THE MERGER AGREEMENT.

      The notice of Special Meeting of stockholders and Proxy Statement follow. Please give this material your careful attention. Please sign and return your proxy promptly, whether or not you plan to attend the Special Meeting. Your vote is very important to Ionics.

      On behalf of Ionics’ directors and officers, I wish to thank you for your interest in Ionics and urge you to vote FOR the approval of the Merger Agreement.

	Sincerely,
	DOUGLAS R. BROWN
	President and Chief Executive Officer

YOUR VOTE IS IMPORTANT

QUESTIONS AND ANSWERS

Q.	When and where will the Special Meeting be held?
A.	The Special Meeting will be held on February 22, 2005 at 1:00 P.M., EST, at Ionics’ principal offices, 65 Grove Street, Watertown, Massachusetts 02472-2882.
Q:	What do I need to do now? (See page 16)
A:	Ionics urges you to read carefully and consider the information contained in this Proxy Statement. In addition, you should complete, sign and date the attached proxy card and return it to Ionics, Incorporated, Proxy Services, c/o EquiServe Trust Company, N.A., P.O. Box 8078, Edison, NJ 08818-9350 in the enclosed postage-prepaid return envelope as soon as possible so that your shares of Ionics common stock may be represented at the Special Meeting.
Q:	What happens if I do not return a proxy card? (See page 17)
A:	The failure to return your proxy card, an abstention from voting or a broker non-vote will have the same effect as a vote against the proposal to approve the Merger Agreement.
Q:	May I vote in person? (See page 16)
A:	Yes. You may vote in person at the meeting, rather than signing and returning your proxy card, if you own shares in your own name. However, Ionics encourages you to return your signed proxy card to ensure that your shares are voted. You may also vote in person at the Special Meeting if your shares are held in “street name” through a broker or bank provided that you bring a legal proxy from your broker or bank and present it at the Special Meeting. You may also be asked to present photo identification for admittance.
Q:	Can I change my vote after I have voted by proxy? (See page 16)
A:	Yes. A stockholder giving a proxy has the power to revoke it at any time prior to its exercise by:

	•	Delivering a written notice of revocation bearing a later date than the proxy to the Secretary of Ionics at or before the taking of the vote at the Special Meeting;
	•	Delivering a duly executed proxy relating to the same shares and bearing a later date to the Secretary of Ionics before the taking of the vote at the Special Meeting; or
	•	Attending the Special Meeting and voting such shares in person. Stockholders should note, however, that merely attending the Special Meeting in person without casting a vote at the meeting will not alone constitute a revocation of a proxy.

Q:	If my shares are held in “street name” by my broker, will my broker vote my shares for me? (See page 16)
A:	Your broker will not vote your shares without instructions from you. You should instruct your broker to vote your shares, following the procedure provided by your broker. Without instructions, your shares will not be voted, which will have the same effect as voting against approval of the Merger Agreement.
Q:	What vote of the stockholders is required to approve the Merger Agreement? (See page 16)
A:	To approve the Merger Agreement, stockholders of record as of January 3, 2005 holding at least two-thirds of the outstanding shares of Ionics common stock must vote FOR the approval of the Merger Agreement. There are 22,974,248 shares of Ionics common stock entitled to be voted at the Special Meeting. Stockholders holding approximately 19.2% of the outstanding shares of Ionics common stock have entered into a Voting Agreement with GE whereby, among other things, such stockholders agreed to vote their shares of Ionics common stock held by them in favor of the Merger Agreement and appointed GE and its designees as their proxy and attorney-in-fact to vote the shares of Ionics common stock held by them in favor of the Merger Agreement.

Table of Contents

Q:	Does Ionics’ board of directors recommend approval of the Merger Agreement? (See page 22)
A:	Yes. Ionics’ board of directors unanimously recommends that its stockholders approve the Merger Agreement. Ionics’ board of directors considered many factors in deciding to recommend the approval of the Merger Agreement. These factors are described below in this Proxy Statement.
Q:	Is the Merger contingent upon approval at the Special Meeting of any of the proposals to be voted upon at the Special Meeting other than the proposal to approve the Merger Agreement?
A:	No.
Q:	What will happen to Ionics as a result of the Merger?
A:	If the Merger is completed, Ionics will become an indirect wholly-owned subsidiary of GE.
Q:	What will happen to my shares of Ionics common stock after the Merger? (See page 42)
A:	Upon completion of the Merger, each outstanding share of Ionics common stock will automatically be canceled and will be converted into the right to receive $44.00 in cash, without interest, subject to any applicable withholding taxes.
Q:	Will I own any shares of Ionics common stock after the Merger or will I receive any shares of GE common stock as a result of the Merger? (See page 42)
A:	No. You will be paid cash for your shares of Ionics common stock. Ionics’ stockholders will not have the option to receive GE common stock in exchange for their shares instead of cash.
Q:	What happens to Ionics stock options in the Merger? (See page 43)
A:	Holders of Ionics stock options will be entitled to receive a cash payment equal to the excess, if any, of $44.00 over the exercise price of such stock option multiplied by the number of shares of common stock subject to such stock option, without interest and subject to any applicable withholding taxes, whether or not then vested or exercisable. GE will not assume any Ionics stock options as a result of the Merger.
Q:	What happens if I sell my shares before the Special Meeting?
A:	The record date for the Special Meeting is earlier than the expected completion date of the Merger. If you held your shares of Ionics common stock on the record date but have transferred those shares after the record date and before the Merger, you may retain your right to vote at the Special Meeting but not the right to receive the merger consideration. This right to receive the merger consideration will pass to the person to whom you transferred your shares of Ionics common stock.
Q:	Will the Merger be taxable to me?
A:	Generally, yes. For U.S. federal income tax purposes, generally you will recognize a taxable gain or loss as a result of the Merger measured by the difference, if any, between $44.00 per share and your adjusted tax basis in that share. This gain or loss will be long-term capital gain or loss if you have held your Ionics shares for more than one year prior to the effective time of the Merger. You should read “The Merger — U.S. Federal Income Tax Treatment” beginning on page 38 for a more complete discussion of the federal income tax consequences of the Merger.
Q:	Am I entitled to dissenter’s or appraisal rights? (See page 36)
A:	Yes, Ionics has concluded that you are entitled under Massachusetts law to appraisal rights in connection with the Merger. To exercise appraisal rights, you must:

	•	Before the vote on the proposal to approve the Merger Agreement is taken, deliver to Ionics written notice of your intent to demand payment for your shares of common stock;
	•	NOT vote in favor of the proposal to approve the Merger Agreement; and

Table of Contents

	•	Comply with other procedures as are required by Part 13 of the Massachusetts Business Corporations Act.

	A copy of the relevant sections of Part 13 of the Massachusetts Business Corporations Act is attached to this Proxy Statement as Annex D.
Q:	Should I send in my stock certificates now? (See page 42)
A:	No. After the Merger is completed, you will receive written instructions for exchanging your shares of Ionics common stock for the merger consideration of $44.00 in cash, without interest and subject to any applicable withholding taxes, for each share of Ionics common stock.
Q:	When do you expect the Merger to be completed?
A:	Ionics is working toward completing the Merger as quickly as possible. In addition to obtaining stockholder approval, Ionics must obtain applicable regulatory approvals and satisfy all other closing conditions. However, Ionics cannot assure you that all conditions to the Merger will be satisfied or, if satisfied, the date by which they will be satisfied.
Q:	When will I receive the cash consideration for my shares of Ionics common stock? (See page 42)
A:	After the Merger is completed, you will receive written instructions, including a letter of transmittal, that explain how to exchange your shares for the cash consideration paid in the Merger. When you properly return and complete the required documentation described in the written instructions, you will promptly receive from the paying agent a payment of the cash consideration for your shares.
Q:	Whom should I contact if I have additional questions?
A:	For more information, you should contact Stephen Korn, Secretary, Ionics, Incorporated, 65 Grove Street, Watertown, Massachusetts 02472-2882, (617) 926-2500 or Georgeson Shareholder toll free at (877) 868-5008.

VOTING AND PROXIES

Who May Vote at the Special Meeting

      Only stockholders of record as of the close of business on January 3, 2005 (the “Record Date”) are entitled to notice of and to vote at the Special Meeting and any adjournments thereof. As of the close of business on the Record Date, the outstanding stock of Ionics entitled to vote consisted of 22,974,248 shares of common stock. The holders of the outstanding shares of Ionics common stock are entitled to one vote per share with respect to each matter submitted to stockholders at the Special Meeting.

How to Vote

      Stockholders may vote in person or by proxy. Execution of a proxy will not affect a stockholder’s right to attend the meeting and vote in person. All shares represented by valid proxies received by the Secretary of Ionics prior to the meeting will be voted as specified in the proxy. If no specification is made and if discretionary authority is conferred by the stockholder, the shares will be voted FOR each of the proposals. Shares of Ionics common stock represented at the Special Meeting but not voted, including shares of Ionics common stock for which proxies have been received but for which stockholders have abstained, will be treated as present at the Special Meeting for purposes of determining the presence or absence of a quorum for the transaction of all business.

      Ionics’ stockholders are requested to complete, date and sign the enclosed proxy card and promptly return it in the accompanying postage-paid envelope. Ionics’ stockholders may vote in person at the Special Meeting by delivering the completed proxy card at the meeting or by using written ballots that will be available to any Ionics’ stockholder who desires to vote in person at the Special Meeting. Ionics’ stockholders who are beneficial owners of shares held in “street name” by a broker, trustee, bank or other nominee holder on behalf of such stockholder may vote in person at the meeting by obtaining a proxy from the nominee holding the Ionics shares. In addition, such Ionics stockholders may vote by proxy by completing and signing a voting instruction card provided to them by the nominee holding the Ionics shares.

How to Change Your Vote

      A stockholder giving a proxy has the power to revoke it at any time prior to its exercise by:

	•	Delivering a written notice of revocation bearing a later date than the proxy to the Secretary of Ionics at or before the taking of the vote at the Special Meeting;
	•	Delivering a duly executed proxy relating to the same shares and bearing a later date to the Secretary of Ionics before the taking of the vote at the Special Meeting; or
	•	Attending the Special Meeting and voting such shares in person. Stockholders should note, however, that merely attending the Special Meeting in person without casting a vote at the meeting will not alone constitute a revocation of a proxy.

Quorum and Vote Required

      The presence, in person or by properly executed proxy, of the holders of at least a majority of the issued and outstanding shares of Ionics common stock entitled to vote at the Special Meeting will constitute a quorum. If a quorum is not present, it is expected that the meeting will be adjourned or postponed to enable Ionics to solicit additional proxies. If a new record date is set for the adjourned meeting, then a new quorum will have to be established. Approval of the Merger Agreement requires the affirmative vote of the holders of at least two-thirds of the outstanding shares of Ionics common stock on the Record Date. Votes cast by proxy or in person at the Special Meeting will be tabulated by the election inspectors appointed for the meeting and will determine whether or not a quorum is present.

16

Table of Contents

      The proposals to be considered at the Special Meeting are of great importance to Ionics. Accordingly, you are urged to read and carefully consider the information presented in this Proxy Statement and to complete, date, sign and promptly return the enclosed proxy in the enclosed postage-paid envelope.

Abstentions and Broker Non-Votes

      Only shares affirmatively voted for the approval of the Merger Agreement, including properly executed proxies that do not contain voting instructions, will be counted as voting for that proposal. If you abstain from voting, it will have the same effect as a vote against the approval of the Merger Agreement and as a vote against the proposal to grant authority to vote to adjourn the Special Meeting. If you do not execute a proxy card, it will have the same effect as a vote against the approval of the Merger Agreement and will have no effect on the proposal to grant authority to vote to adjourn the Special Meeting. Brokers who hold shares in street name for customers have the authority to vote on “routine” proposals when they have not received instructions from beneficial owners. However, brokers are precluded from exercising their voting discretion with respect to approval of non-routine matters, such as the approval of the Merger Agreement and, as a result, absent specific instructions from the beneficial owner of such shares, brokers are not empowered to vote those shares, referred to generally as “broker non-votes.” Broker non-votes will be treated as shares that are present and entitled to vote at the Special Meeting for purposes of determining whether a quorum exists and will have the same effect as votes “against” the approval of the Merger Agreement. Broker non-votes will have no effect on the proposal to grant the persons named as proxies the authority to vote to adjourn the Special Meeting.

Other Meeting Matters and Adjournment

      The Ionics board of directors does not know of any matters other than those described in the notice of the Special Meeting that are to come before the Special Meeting. If any other matters are properly brought before the Special Meeting, including, among other things, a motion to adjourn or postpone the Special Meeting to another time and/or place for the purpose of soliciting additional proxies in favor of the proposal to approve the Merger Agreement or to permit the dissemination of information regarding material developments relating to the proposal to approve the Merger Agreement or otherwise germane to the Special Meeting, one or more persons named in the Ionics form of proxy will vote the shares represented by such proxy upon such matter as determined in their discretion. If it is necessary to adjourn the Special Meeting, no notice of the time and place of the adjourned meeting is required to be given to Ionics’ stockholders other than the announcement of such time and place at the Special Meeting. At any subsequent reconvening of the Special Meeting, all proxies will be voted in the same manner as such proxies would have been voted at the original convening of the meeting (except for any proxies which theretofore have been effectively revoked or withdrawn). The affirmative vote of at least a majority of the shares of common stock entitled to vote present, in person or by proxy, and voting at the Special Meeting although less than a quorum, is required to approve such adjournment.

Solicitation of Proxies

      The cost of solicitation of proxies will be borne by Ionics. In addition to soliciting stockholders by mail, certain of Ionics’ directors, officers and employees, without additional remuneration, may solicit proxies in person or by telephone or other means of electronic communication. Ionics will not pay these individuals for their solicitation activity but will reimburse them for their reasonable out-of-pocket expenses. Brokers and other custodians, nominees and fiduciaries will be requested to forward proxy-soliciting material to the owners of stock held in their names, and Ionics will reimburse such brokers and other custodians, nominees and fiduciaries for their reasonable out-of-pocket costs. Solicitation by directors, officers and employees of Ionics may also be made of some stockholders in person or by mail, telephone or other means of electronic communication following the original solicitation. Ionics has retained an independent proxy solicitation firm, Georgeson Shareholder Communications, Inc. (“Georgeson Shareholder”), to assist in soliciting proxies. Ionics has agreed to pay Georgeson Shareholder fees for proxy solicitation services in the amount of $15,000 in fixed fees plus additional fees based on the

      The SEC has adopted rules that permit companies and intermediaries (for example, brokers) to satisfy the delivery requirements for proxy statements with respect to two or more stockholders sharing the same address if Ionics believes the stockholders are members of the same family by delivering a single proxy statement addressed to those stockholders. Each stockholder will continue to receive a separate proxy card or voting instruction card. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies by reducing the volume of duplicate information.

      A number of brokers with account holders who are Ionics’ stockholders will be “householding” Ionics’ proxy materials. A single proxy statement will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker or Ionics that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. If your household received a single proxy statement, but you would prefer to receive your own copy, please notify your broker and direct your written request to Ionics, Incorporated, Attention: Director, Investor Relations, 65 Grove Street, Watertown, Massachusetts 02472-2882, or contact Ionics’ Investor Relations Department at (617) 926-2500. If your household received multiple proxy statements, but you would like to receive one set of Ionics’ proxy materials in the future:

	•	If your Ionics shares are registered in your own name, please contact Ionics’ transfer agent, EquiServe LP, by phone at (781) 575-3120, or by mail to 150 Royall Street, Canton, Massachusetts 02021; or
	•	If a broker or other nominee holds your Ionics shares, please contact your broker and Ionics, Incorporated, Investor Relations and inform them of your request. Be sure to include your name, the name of your brokerage firm and your account number.

THE MERGER

      This section describes material aspects of the Merger, including the Merger Agreement. While Ionics believes that the description covers the material terms of the Merger and the Merger Agreement, this summary may not contain all of the information that is important to you. You should read carefully this entire document and the other documents referred to in this Proxy Statement for a more complete understanding of the Merger and the Merger Agreement.

      Ionics’ stockholders are being asked to consider and act upon a proposal to approve the Merger Agreement. The Merger Agreement provides for the acquisition of all the outstanding shares of common stock of Ionics for $44.00 in cash per share of common stock. The Merger will not be completed unless the Merger Agreement is approved.

Background of the Proposed Merger

      On April 15, 2004, Douglas R. Brown (Ionics’ President and Chief Executive Officer) and Lyman B. Dickerson (Ionics’ Vice President, Water Systems Division) met with George R. Oliver (Vice President and General Manager of Water and Process Technologies, GE Infrastructure) to discuss potential business relationships between Ionics and GE.

      On June 10, 2004, Mr. Brown and Theodore G. Papastavros (Ionics’ retired Executive Vice President who is serving as a consultant to Ionics) met at GE Water’s offices in Minnesota with Mr. Oliver, Robert Jeffe (former Senior Vice President, Business Development of GE) and Phil Rolchigo (Technology Leader of GE Infrastructure). At this meeting, Ionics and GE presented information regarding their respective process technologies.

      On June 18, 2004, Stephen Korn (Ionics’ Vice President and General Counsel) delivered to Scott Seeley (General Counsel of GE Infrastructure) a draft confidentiality agreement. Between June 18, 2004 and July 2, 2004, Mr. Korn and representatives of Testa, Hurwitz & Thibeault, LLP (Ionics’ legal counsel) and Mr. Seeley and James R. Billingsley, Jr. (Senior Counsel — Transactions of GE Infrastructure) negotiated a reciprocal confidentiality agreement. On July 2, 2004, Ionics and GE, acting through its GE Infrastructure business unit, entered into a reciprocal confidentiality agreement.

      On July 7, 2004, Messrs. Brown and Papastavros met with William A. Woodburn (President and Chief Executive Officer of GE Infrastructure), and Mr. Oliver at Ionics. At this meeting, a range of business relationships were discussed ranging from cooperation on mobile demineralization to a merger.

      On July 22, 2004, Messrs. Brown and Woodburn met in Cambridge, Massachusetts to discuss a possible business combination between Ionics and GE.

      On August 22, 2004, Messrs. Dickerson and Oliver met in Virginia Beach, Virginia to discuss potential opportunities to work together in providing services.

      On September 23, 2004, Mr. Brown met with Messrs. Woodburn and Oliver to discuss further a possible business combination between Ionics and GE, including the structure of a possible combination and the valuation of Ionics.

      On October 7, 2004, Mr. Brown met with Messrs. Woodburn and Oliver at GE Infrastructure’s offices in Wilton, Connecticut to discuss further a possible business combination between Ionics and GE, including the structure of a possible combination, the form of the consideration and the valuation of Ionics.

      On November 1, 2004, Messrs. Brown and Dickerson met with Jeffrey Immelt (GE’s Chairman and Chief Executive Officer) and Mr. Woodburn to discuss a possible business combination between Ionics and GE, including the strategic fit of the businesses, the potential synergies resulting from such a combination and the structure and valuation of a possible combination. Messrs. Brown, Dickerson, Woodburn and Derek Feng (General Manager — Business Development of GE Infrastructure) also met to discuss diligence requirements, transaction timing and the form of consideration.

      From November 3, 2004 through November 23, 2004, representatives from GE and Weil, Gotshal & Manges LLP (GE’s legal counsel) conducted due diligence reviews of Ionics. On November 4, 2004 at the offices of Testa, Hurwitz & Thibeault, LLP in Boston, Massachusetts, Messrs. Brown, Dickerson, Papastavros and Korn, John F. Curtis (Ionics’ Vice President, Strategy & Operations) and Daniel M. Kuzmak (Ionics’ Vice President and Chief Financial Officer) made presentations to Messrs. Woodburn, Oliver, Feng, Seeley and other representatives from GE regarding Ionics’ business, operations, strategic plans, historical and projected financial performance, and potential synergies realizable from a business combination. Also in attendance at that meeting were representatives from Goldman Sachs and UBS (Ionics’ financial advisors) and Testa, Hurwitz & Thibeault, LLP.

      On November 11, 2004, Weil, Gotshal & Manges LLP delivered to Testa, Hurwitz & Thibeault, LLP first drafts of the Merger Agreement and the Voting Agreement. From November 15, 2004 to November 24, 2004, representatives of Ionics and GE and their respective legal counsel negotiated the terms and conditions of the proposed business combination, including the Merger Agreement. These negotiations covered all aspects of the proposed transaction. The terms of the Merger Agreement, including the consideration to be paid in the Merger to Ionics’ stockholders, were the result of arm’s-length negotiations between Ionics and GE. The consideration to be paid in the Merger to Ionics’ stockholders resulted from arm’s-length negotiations principally between Mr. Brown and representatives of GE, principally Mr. Woodburn. In negotiating the consideration to be paid in the Merger, Mr. Brown considered the form of the consideration, the premium the proposed consideration represented to the then current market price for Ionics shares, the enterprise value of Ionics based on the proposed consideration as a multiple of various estimated operating statistics, and information regarding the valuation multiples paid in other transactions, among other things. Also, from November 22, 2004 to November 24, 2004, Mr. Dickerson and GE and their respective legal counsel negotiated the terms and conditions of the Voting Agreement. GE required a voting agreement from the Ecolochem Holders as a condition to entering into the Merger Agreement. As consideration for entering into the Voting Agreement, Mr. Dickerson and the other Ecolochem Holders principally sought to have all cash and Ionics common stock held in escrow to secure a portion of their indemnification obligations to Ionics released upon completion of the Merger. For a description of the Voting Agreement, see “Voting Agreement” beginning on page 52.

      On November 24, 2004, Ionics and GE entered into the Merger Agreement. On November 24, 2004, GE, and the Ecolochem Holders entered into the Voting Agreement. Before the opening of the market on November 24, 2004, Ionics and GE jointly announced their entry into the Merger Agreement.

Reasons for the Merger

      The Ionics board of directors has unanimously determined that the Merger Agreement and the transactions contemplated thereby (including the Merger) are advisable and in the best interests of Ionics and its stockholders, has unanimously adopted and approved the Merger Agreement, and has unanimously approved the transactions contemplated thereby. The Ionics board of directors unanimously recommends that holders of Ionics common stock vote FOR the proposal to approve the Merger Agreement and the transactions contemplated thereby (including the Merger).

      In evaluating, adopting and approving the Merger Agreement and the Merger and recommending that the holders of Ionics common stock vote to approve the Merger Agreement and the transactions contemplated thereby (including the Merger), the Ionics board of directors retained Goldman Sachs and

Table of Contents

	•	The premium that the merger consideration of $44.00 per share represented in comparison to the closing price per share of the Ionics common stock on November 22, 2004 (the last trading day prior to the date the Ionics board of directors acted on the matter) ($30.21), and the average share price of the Ionics common stock for the previous four weeks ($30.14), previous three months ($27.91), previous six months ($27.01), and previous twelve months ($27.62);
	•	That the merger consideration is all cash, which provides certainty of value to Ionics’ stockholders;
	•	The likelihood that the Merger will be consummated, in light of the experience, reputation and financial capability of GE and the absence of any financing condition to GE’s obligation to complete the Merger;
	•	The business, financial, market and execution risks associated with remaining independent and successfully implementing Ionics’ business strategies;
	•	The financial analyses of Goldman Sachs and UBS presented to the Ionics board of directors on November  23, 2004, and the opinions of Goldman Sachs and UBS delivered to the Ionics board of directors that, as of November 24, 2004, and based upon and subject to the various factors, assumptions, limitations and qualifications set forth in their respective opinions, the $44.00 in cash per share of Ionics common stock to be received by holders of shares of Ionics common stock pursuant to the Merger Agreement was fair, from a financial point of view, to those holders (the full text of the opinions setting forth the assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with the opinions, are attached as Annexes B-1 and B-2 to this Proxy Statement);
	•	The terms and conditions of the Merger Agreement, including:

	•	The scope of the representations, warranties and covenants being made by Ionics;
	•	The conditions to the consummation of the Merger, including the requirement that the Merger Agreement be approved by Ionics’ stockholders;
	•	The ability of the Ionics board of directors, in the exercise of its fiduciary duties in accordance with the Merger Agreement, to provide information to, engage in negotiations with, change its recommendation to stockholders to approve the Merger Agreement and potentially enter into a transaction with another party in connection with any unsolicited, bona fide written proposal that the Ionics board of directors determines in good faith constitutes, or is reasonably likely to result in, a superior proposal in the manner provided in the Merger Agreement, subject to specified conditions, including if the Ionics board of directors accepts or recommends such a superior proposal, paying a $33,000,000 termination fee to GE, which is approximately 3% of the total merger consideration;

	•	The terms and conditions of the Voting Agreement (to which Ionics is not a party), including the support under the Voting Agreement for the adoption of the Merger Agreement by the holders of approximately 19.2% of the outstanding shares of Ionics common stock and the automatic termination of the Voting Agreement upon the termination of the Merger Agreement, which would be important if the Ionics board of directors terminated the Merger Agreement to accept a superior proposal as permitted under the Merger Agreement; and
	•	The business reputation and the substantial, liquid financial resources of GE which the Ionics board of directors believes will provide Ionics’ business with significant resources to grow and execute its growth strategy more rapidly than as a stand-alone company and the potential to penetrate existing and new markets.

Table of Contents

      The Ionics board of directors also considered a number of potentially countervailing factors in its deliberations concerning the Merger, including the following:

	•	That Ionics will no longer exist as an independent company and its stockholders will no longer participate in Ionics’ growth or from any future increase in the value of Ionics or from any synergies that may be created by the Merger;
	•	That, under the terms of the Merger Agreement, Ionics cannot solicit other acquisition proposals and must pay or cause to be paid to GE a termination fee of $33,000,000 in cash if the Merger Agreement is terminated under certain circumstances specified in the Merger Agreement, including if the Ionics board of directors exercises its right to terminate the Merger Agreement and enter into an alternative superior transaction, which may deter others from proposing an alternative transaction that may be more advantageous to Ionics’ stockholders;
	•	That gains from this all-cash transaction will be taxable to Ionics’ stockholders for U.S. federal income tax purposes; and
	•	That if the Merger does not close, Ionics’ officers and other employees will have expended extensive efforts attempting to complete the transaction and will have experienced significant distractions from their work during the pendency of the transaction and Ionics will have incurred substantial transaction costs in connection with the transaction and such costs will negatively impact Ionics’ operating results.

      The Ionics board of directors considered all of the above in light of Ionics’ historical and projected business, operations, assets, financial condition, operating results and cash flows and prospects.

      The Ionics board of directors also considered the interests of its directors and executive officers in the transactions contemplated by the Merger Agreement and the Voting Agreement, which are described below under “The Merger — Interests of Certain Persons in the Merger.”

      The Ionics board of directors concluded that, on balance, the potential benefits to Ionics and its stockholders of the transactions contemplated by the Merger Agreement and the Voting Agreement outweighed the potential disadvantages and risks associated with those transactions. The foregoing discussion of the information and factors considered by the Ionics board of directors is not intended to be exhaustive. In view of the variety of factors considered in connection with its evaluations, the Ionics board of directors did not find it practicable to, and did not quantify or otherwise assign relative weight to, the specific factors considered in reaching its determination. Instead, the Ionics board of directors conducted an overall analysis of the factors described above, including summaries of discussions of Ionics’ management with Ionics’ legal, financial, accounting, tax and other advisors. In considering the factors described above, individual directors may have given different weights to different factors.

Recommendation of the Ionics Board of Directors

      The Ionics board of directors unanimously recommends that you vote FOR the proposal to approve the Merger Agreement. The Ionics board of directors has unanimously determined that the Merger is advisable and in the best interests of Ionics and its stockholders.

Opinions of Ionics’ Financial Advisors

      The Ionics board of directors selected both Goldman Sachs and UBS as its financial advisors because it believed that using the two firms would assist it in obtaining the highest value for Ionics stockholders. Both firms are internationally recognized investment banking firms that have substantial experience in transactions similar to the transaction contemplated by the Merger Agreement, have significant knowledge of and prior relationships with Ionics, and have significant knowledge of the industries in which Ionics conducts business. Both firms were engaged to act as Ionics’ financial advisors at approximately the same time. Throughout the period of their engagements, both firms provided financial advice and assistance to Ionics in connection with the Merger, including assisting Ionics in analyzing the transaction; advising

The Ionics board of directors received assurances from each of Goldman Sachs and UBS that it had not been engaged by GE with respect to a potential transaction with Ionics. The Ionics board of directors did not consider the amount of fees for investment banking and other services paid by GE to either Goldman Sachs or UBS.

	Goldman Sachs

	•	certain internal financial analyses and forecasts for Ionics prepared by its management.

In addition, Goldman Sachs reviewed the reported price and trading activity for the shares of Ionics common stock, compared certain financial and stock market information for Ionics with similar information for certain other companies the securities of which are publicly traded, reviewed the financial terms of certain recent business combinations in the water technology industry specifically and in other

	UBS

      UBS rendered its opinion to the Ionics board of directors that, as of November 24, 2004 and based upon and subject to the assumptions, limitations and qualifications set forth in such opinion, the $44.00 in cash per share of Ionics common stock to be received by the holders of shares of Ionics common stock in the Merger was fair, from a financial point of view, to such holders.

UBS assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the transactions contemplated by the Merger Agreement would be obtained without any material adverse effect on Ionics or the Merger. UBS’ opinion was necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to UBS as of, November 24, 2004.

      UBS’ opinion did not address the relative merits of the Merger as compared to other business strategies or transactions that might be available to Ionics or its underlying business decision to effect the Merger, nor did it constitute a recommendation to any shareholder as to how such shareholder should vote with respect to the Merger Agreement. UBS was neither asked to, nor did it, offer any opinion as to any terms of the Merger Agreement or related documents and the obligations thereunder, or the form of the Merger.

The following summary, however, does not purport to be a complete description of the financial analyses performed by Goldman Sachs and UBS. The order of analyses described does not represent relative importance or weight given to those analyses by Goldman Sachs and UBS. Some of the summaries of the financial analyses include information presented in tabular format.

      Selected Companies Analysis. Goldman Sachs and UBS reviewed and compared certain financial information for Ionics to corresponding financial information, ratios and public market multiples for the following selected publicly traded companies in the water technology industry:

	•	BWT AG
	•	Calgon Carbon Corporation
	•	CUNO Incorporated
	•	ESCO Technologies Inc.
	•	Kurita Water Industries Ltd
	•	Millipore Corporation
	•	Pall Corporation
	•	Severn Trent Plc
	•	Zenon Environmental Inc.

      Although none of the selected companies was directly comparable to Ionics, the companies included were chosen because they are publicly traded companies with business, end markets and operations that, for purposes of analysis, could be considered similar to certain business, end markets and operations of Ionics.

      Goldman Sachs and UBS calculated and compared various public market multiples and ratios of the selected companies based on information it obtained from SEC filings and median estimates provided by the Institutional Brokerage Estimate System, or IBES (a data service that compiles estimates issued by securities analysts). The multiples and ratios of Ionics were based on IBES median estimates and Ionics management’s estimates. The multiples and ratios of Ionics and of the selected companies were calculated using public trading market closing prices on November 22, 2004 and using the $44.00 per share to be received by holders of Ionics common stock. With respect to Ionics and the selected companies, Goldman Sachs and UBS calculated:

	•	the enterprise value, which is the value of common equity, calculated using the per share price and fully diluted shares outstanding based on each company’s latest publicly available information, plus book value of net debt, which is total debt less cash and cash equivalents, plus book value of minority interest, as a multiple of last twelve months, or LTM, sales;
	•	the enterprise value as a multiple of LTM and estimated 2004 and 2005 EBITDA (earnings before interest, taxes, depreciation and amortization);
	•	the enterprise value as a multiple of LTM EBIT (earnings before interest and taxes);

Table of Contents

	•	the ratio of the price per share to the estimated 2004 and 2005 EPS (earnings per share), or P/ E multiple;
	•	the ratio of the estimated 2005 P/ E multiple to the five-year EPS estimated compound annual growth rate, or CAGR;
	•	LTM EBITDA and EBIT margins, calculated by dividing each company’s LTM EBITDA and EBIT by its LTM sales; and
	•	the dividend yield as of November 22, 2004.

      Historical financial results utilized by Goldman Sachs and UBS for purposes of this analysis were based upon information contained in the applicable company’s latest publicly available financial statements prior to November 22, 2004. The LTM period for this analysis refers to the latest twelve-month period from the most recent publicly available information for Ionics and the selected companies as of November 22, 2004. Ionics’ financial results for the LTM period were calculated, as provided by Ionics management, on a pro forma basis to consolidate the financial performance of the Desalination Company of Trinidad and Tobago Ltd. (which we refer to as Desalcott), which Ionics began consolidating on January 1, 2004, and to account for the purchase of Ecolochem, Inc., which was completed on February 13, 2004. Ionics’ net debt utilized in this analysis, as provided by Ionics management, included debt of Desalcott which is non-recourse to Ionics. Ionics’ LTM EBITDA and EBIT, estimated 2004 and 2005 EBITDA and estimated EPS included adjustments by Ionics management for certain one-time charges. Ionics management calculated Ionics’ estimated 2004 and 2005 EPS based on average diluted shares outstanding.

      Estimates of future results used by Goldman Sachs and UBS in this analysis, for the selected companies, were based on median estimates provided by IBES and calendarized to year-end December 31, and for Ionics, were based on median estimates provided by IBES calendarized to year-end December 31 and estimates by Ionics management.

      Implied Transaction Multiples. Goldman Sachs and UBS calculated the $44.00 per share purchase price to be received by holders of shares of Ionics common stock pursuant to the Merger Agreement as a multiple of EPS, the fully diluted equity consideration as a multiple of Ionics’ estimated 2004 year-end book value and the enterprise value amount as a multiple of other historical and estimated financial results for Ionics as follows:

	•	Sales, EBITDA and EBIT provided by Ionics management, for the LTM period ended September 30, 2004;
	•	Ionics management’s estimates of sales, EBITDA, EBIT and EPS for 2004 and 2005, and estimated run-rate 2004 EBITDA calculated by Ionics management by annualizing the EBITDA for the second and third quarters of 2004; and
	•	median sales, EBITDA, operating income and EPS estimates for 2004 and 2005 provided by IBES, as of November 22, 2004.

      LTM sales, EBITDA and EBIT were calculated, as provided by Ionics management, on a pro forma basis to account for the purchase of Ecolochem, Inc., which was completed on February 13, 2004, and to consolidate Desalcott’s financial performance, which Ionics began consolidating on January 1, 2004. Ionics management’s estimates and LTM figures for EBITDA, run-rate EBITDA, EBIT and EPS included adjustments by Ionics management for certain one-time charges.

March 1999		Vivendi		U.S. Filter Corp.

      None of the selected transactions nor the companies involved in them is directly comparable to the Merger or Ionics.

      For each of the selected transactions and for the transaction contemplated by the Merger Agreement, Goldman Sachs and UBS calculated and compared the resulting:

	•	enterprise value;
	•	enterprise value as a multiple of LTM sales, LTM EBITDA and LTM EBIT; and
	•	implied equity value per share premium to the four-weeks prior stock price.

      For purposes of this analysis, enterprise value was calculated by determining each target company’s implied equity value and then adding the book value of each target company’s net debt and minority interest, or was obtained from other publicly disclosed information as of the respective announcement dates. LTM sales, EBITDA, EBIT, net debt and minority interest were calculated using each target

      Discounted Cash Flow Analysis. Goldman Sachs and UBS performed a discounted cash flow analysis on Ionics using Ionics management’s estimates for fiscal years 2005-2010. Goldman Sachs and UBS calculated implied present values of free cash flows for Ionics for the fiscal years 2005 through 2010 using discount rates ranging from 10% to 12%. Goldman Sachs and UBS calculated the implied terminal value for Ionics using multiples ranging from 8.0x to 11.0x 2010 terminal year estimated EBITDA, which was adjusted to include cash dividends from affiliates. The implied terminal values were then discounted back to December 31, 2004 using discount rates ranging from 10% to 12%. The calculations of the implied present values of free cash flows plus the implied present value of the implied terminal value was summed by Goldman Sachs and UBS to arrive at implied enterprise values. Implied equity values were calculated by Goldman Sachs and UBS as the implied enterprise values less estimated book value of net debt (which consists of estimated total debt as of December 31, 2004, less estimated Desalcott debt that is non-recourse to Ionics, estimated cash and cash equivalents) and estimated book value of minority interest, as provided by Ionics management. Implied prices per share of Ionics common stock were calculated based on the fully diluted shares of Ionics common stock outstanding as of September 30, 2004 provided by Ionics’ management and assumes that 4.5 million options were outstanding with a weighted average strike price of $25.30 per share. For purposes of this analysis, the Ionics financial results did not consolidate Desalcott financial performance and were adjusted for certain one-time charges. Estimates of Ionics’ financial results utilized in this analysis, as well as the adjustments for certain one-time charges, were provided to Goldman Sachs and UBS by Ionics management. This analysis resulted in implied enterprise values ranging from $774 million to $1,105 million and implied per share of Ionics common stock values ranging from $28.54 to $40.95.

      The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary set forth herein, without considering the analyses as a whole, could create an incomplete view of the processes underlying the opinions of Goldman Sachs and UBS. In arriving at their respective fairness determinations, Goldman Sachs and UBS each separately considered the results of all of their analyses and did not attribute any particular weight to any factor or analysis considered by them. Rather, Goldman Sachs and UBS each separately made their respective determinations as to fairness on the basis of their experience and professional judgment after considering the results of all of their analyses. No company or transaction used in the analyses described herein as a comparison is directly comparable to Ionics or the contemplated transaction.

      Goldman Sachs and UBS prepared the analyses described herein for purposes of providing their respective opinions to the Ionics board of directors as to the fairness from a financial point of view to the holders of shares of Ionics common stock of the consideration to be received by such holders in the Merger contemplated by the Merger Agreement. These analyses do not purport to be appraisals or necessarily reflect the prices at which businesses or securities actually may be sold. Analyses based upon forecasts of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by these analyses. Because these analyses are inherently subject to

      As described above, the respective opinions of Goldman Sachs and UBS to the Ionics board of directors were one of many factors taken into consideration by the Ionics board of directors in making its determination to approve the transaction contemplated by the Merger Agreement. Goldman Sachs and UBS were not asked to, and did not, recommend the specific consideration payable in the Merger, which consideration was determined through negotiations between GE and Ionics. The summary contained herein does not purport to be a complete description of the analyses performed by Goldman Sachs and UBS in connection with their respective fairness opinions and is qualified in its entirety by reference to the opinion of Goldman Sachs and the opinion of UBS, attached as Annex B-1 and Annex B-2, respectively.

Interests of Certain Persons in the Merger

      In considering the recommendation of Ionics’ board of directors in favor of the Merger, you should be aware that there are provisions of the Merger Agreement, the Voting Agreement and other existing agreements that will result in certain benefits to Ionics’ directors and executive officers that are not available to stockholders generally. Ionics’ board of directors was aware of, and considered the interests of, its directors and executive officers and the potential conflicts arising from such interests in its deliberations of the merits of the Merger and in adopting and approving the Merger Agreement and the Merger. Other than the provisions of the Merger Agreement and the Voting Agreement described below, and the bonuses described below that were not contractually required, the arrangements described below were in existence before the discussions about the Merger began. Stockholders should take these benefits into account in deciding whether to vote for approval of the Merger Agreement.

      Stock Options. In connection with the Merger, the Ionics board of directors authorized the acceleration of the vesting of options to purchase shares of Ionics common stock held by certain executive officers of Ionics and gave the chief executive officer the authority to accelerate such options. As of January 26, 2005, no such options have been accelerated.

      In addition, upon the completion of the Merger, all Ionics stock options will immediately vest and become exercisable. All outstanding stock options will be converted at the effective time into the right to receive a cash payment equal to the excess, if any, of $44.00 over the exercise price of such stock option multiplied by the number of shares subject to such stock option. The following table sets forth as of January 26, 2005, the number of shares of Ionics common stock subject to options held by Ionics’ executive officers and directors, the number of shares of Ionics common stock subject to options held by such persons that will vest as a result of the Merger and the estimated cash payment such persons will receive pursuant to the conversion of their options.

Note:	The table does not include stock options with an exercise price exceeding $44.00 per share of Ionics common stock.

      Stock Ownership. Many of Ionics’ officers and directors also beneficially own shares of Ionics common stock. For a further description of these stock holdings, see “Security Ownership of Certain Beneficial Owners and Management” beginning on page 53.

      Severance Arrangements under Existing Employment Agreements. Ionics has entered into employment agreements with each of Douglas R. Brown, John F. Curtis and Lyman B. Dickerson that provide for salary and other employment terms. Each agreement also provides that if, among other events, (i) the employee terminates his employment for good cause (as defined in each employment agreement) within 24 months of a change in control or (ii) Ionics terminates the employee’s employment without cause (as defined in each employment agreement), then the employee shall receive a severance benefit equal to 18 months of his then-current base salary plus an amount equal to 1.5 times the employee’s target bonus for the fiscal year in which such termination occurs, in addition to any benefits required to be paid by law and the customary post-termination benefits in accordance with Ionics’ retirement, insurance and other benefit plans and arrangements, including any earned but unpaid bonus. On November 23, 2004, the Ionics board of directors established target bonuses for the fiscal year ending December 31, 2005 for Messrs. Brown, Curtis and Dickerson of $600,000, $300,000 and $250,000, respectively. The severance benefits payable to Messrs. Brown, Curtis and Dickerson under these employment agreements if their employment were terminated under such circumstances would be $1,500,000, $975,000 and $750,000, respectively. As of the date of this Proxy Statement, GE has not indicated to Ionics on what basis the employment of Messrs. Brown, Curtis and Dickerson will be continued, or if it will be continued, after the completion of the Merger. As a result, Ionics is not aware of whether such severance benefits will be paid.

      Severance Arrangements under Existing Employee Retention Agreements. Ionics has entered into employee retention agreements with each of the following executive officers: Edward Cichon, Alan Crosby, Anthony DiPaola, Stephen Korn and Daniel Kuzmak. Pursuant to each such retention agreement, if within 24 months of a change in control, a successor to Ionics terminates the employee other than for cause (as defined in each retention agreement) or the employee terminates his employment for good

      Executive Bonus Payments. On November 23, 2004, the Ionics board of directors approved the payment of an aggregate of $870,000 in cash bonuses to 11 management employees with respect to the fiscal year ended December 31, 2004. These bonuses, which were paid during December 2004, included bonuses of $100,000 to each of Messrs. Brown, Curtis and Kuzmak and bonuses of $75,000 to each of Messrs. Cichon and Korn. These bonuses were in addition to the contractually required cash bonuses of $400,000 and $150,000 to Messrs. Brown and Curtis, respectively, which were also paid during December 2004.

      In addition, the Ionics board of directors approved the payment of an aggregate of up to another $630,000 in cash bonuses to Ionics’ employees (other than Messrs. Brown and Dickerson) with respect to the fiscal year ended December 31, 2004. These bonuses will be paid to employees (which may include certain executive officers), in the amounts and at the times determined by Ionics’ Chief Executive Officer. To date, Mr. Korn is the only named executive officer to receive such a bonus, which was for $25,000.

      Indemnification of Directors and Executive Officers and Insurance. The Merger Agreement provides that GE will cause Ionics, as the surviving corporation in the Merger, to indemnify the individuals who were at or prior to the Closing Date directors or officers of Ionics with respect to actions or omissions by them as such at any time prior to the Closing Date to the fullest extent permitted by (i) Ionics’ certificate of incorporation or bylaws in effect as of November 24, 2004, (ii) any applicable contract in effect as of November 24, 2004 and (iii) applicable law; provided that such persons shall not be indemnified for any criminal conduct, fraud or breach of the Merger Agreement. The Merger Agreement further provides that, after the Merger, GE will, or will cause Ionics as the surviving corporation to provide, for a period not less than six years, directors’ and officers’ liability insurance covering those persons who were, as of the date of the Merger Agreement, covered by Ionics’ directors’ and officers’ liability insurance policy, on terms no less favorable than those in effect on the date of the Merger Agreement. GE will not be required to pay an annual premium for such insurance that exceeds 150% of the annual premium that Ionics currently pays for such insurance.

      Ecolochem Escrow Agreement. In connection with Ionics’ acquisition of the Ecolochem Group on February 13, 2004, the Ecolochem Holders agreed to indemnify Ionics for losses arising from certain breaches of representations, warranties, covenants and agreements made by them in the definitive acquisition agreement. To secure a portion of the Ecolochem Holders’ indemnification obligations, $20,000,000 in cash and 490,566 shares of Ionics common stock (which constitutes only a portion of the cash and shares received by the Ecolochem Holders in the acquisition) were escrowed pursuant to the Escrow Agreement dated as of February 13, 2004 by and among Ionics and the Ecolochem Holders (the “Ecolochem Escrow Agreement”). Subject to certain limitations, on February 13, 2005, the escrow agent is required to distribute to the Ecolochem Holders any amounts held in escrow in excess of 50% of the escrowed cash and shares of Ionics common stock, less the amount of any pending claims for indemnification. Subject to certain limitations, on February 13, 2006, the escrow agent is required to distribute to the Ecolochem Holders any remaining amounts held in escrow, less the amount of any

Table of Contents

      As consideration for the Ecolochem Holders’ agreement to enter into the Voting Agreement and to vote their shares of Ionics common stock in favor of the Merger Agreement, GE agreed that, after the completion of the Merger, any remaining amounts then held in escrow (less the amount of any pending claims for indemnification) will be distributed to the Ecolochem Holders. While the Ecolochem Holders will still be liable for indemnification claims, the escrowed amounts will be distributed to them earlier than contemplated by the Ecolochem Escrow Agreement. Lyman Dickerson, a director and executive officer of Ionics, and persons related to him beneficially own all of the cash and shares of Ionics common stock held in escrow and may be deemed to benefit from shortening the deadline for recovery of indemnification claims from the escrowed amounts and the resulting release of the cash and Ionics common stock from escrow.

Appraisal Rights

      The Massachusetts legislature adopted a new Massachusetts Business Corporation Act (the “MBCA”) in July 2004, which repealed and replaced the Massachusetts Business Corporation Law, including the provisions related to appraisal rights.

      General. Section 13.02(a) of the MBCA provides generally that stockholders of Massachusetts corporations are entitled to appraisal rights in the event of a merger. Although an exemption set forth in Section 13.02(a)(1) of the MBCA provides that stockholders are not entitled to appraisal rights in transactions similar to the Merger where cash is the sole consideration received by the stockholders, Ionics believes that certain persons or entities may have a direct or indirect material financial interest in the Merger, as described in the section entitled “The Merger — Interests of Certain Persons in the Merger” on page 33, which renders this exemption inapplicable with respect to the Merger. Accordingly, Ionics believes its stockholders are entitled to appraisal rights under Massachusetts law.

      Any stockholder who wishes to exercise appraisal rights or who wishes to preserve that right should review carefully the following discussion and Sections 13.01 through 13.31 of Part 13 of the MBCA, attached as Annex D to this Proxy Statement. Failure to strictly comply with the procedures specified in Part 13 of the MBCA will result in the loss of appraisal rights.

      Notice of Intent and Demand for Payment. Any holder of Ionics common stock wishing to exercise the right to demand appraisal under Part 13 of the MBCA must satisfy each of the following conditions:

	•	Before the vote to approve the Merger Agreement is taken, an Ionics stockholder electing to exercise his or her appraisal rights must deliver to Ionics written notice of such stockholder’s intent to demand payment for his or her shares if the Merger is completed. The written notice should be delivered to Stephen Korn, Secretary, Ionics, Incorporated, 65 Grove Street, Watertown, Massachusetts 02472-2882. Ionics recommends you send your notice by registered or certified mail, return receipt requested; and
	•	An Ionics stockholder electing to exercise his or her appraisal rights must NOT vote in favor of the proposal to approve the Merger Agreement. If a stockholder returns a signed proxy but does not specify a vote against the proposal to approve the Merger Agreement or a direction to abstain, the proxy will be voted FOR the Merger Agreement, which will have the effect of waiving that stockholder’s appraisal rights.

      Generally, a stockholder may assert appraisal rights only if the stockholder seeks them with respect to all of the holder’s shares of common stock. Stockholders of record for more than one beneficial stockholder may assert appraisal rights with respect to fewer than all the shares registered in such stockholder’s name as holder of record, provided that such stockholder notifies Ionics in writing of the name and address of each beneficial stockholder on whose behalf such stockholder is asserting appraisal rights. For a beneficial stockholder to assert appraisal rights, such beneficial stockholder must submit to Ionics such record stockholder’s written consent to the assertion of such rights not fewer than 40 nor more than 60 days after Ionics sends out written notice to the stockholder of appraisal rights, as described

36

      Appraisal Notice and Form. If the Merger Agreement is approved, within 10 days after the effective date of the Merger, Ionics will deliver a written appraisal notice and a form containing certain information to all stockholders who have properly demanded appraisal rights. The appraisal notice will include a copy of Part 13 of the MBCA and a form that specifies the date of the first announcement to stockholders of the principal terms of the Merger. The form will require the stockholder asserting appraisal rights to certify (i) whether or not beneficial ownership of the shares for which appraisal rights are asserted were acquired before the date of the first announcement of the proposed Merger and (ii) that the stockholder did not vote for proposal to approve the Merger Agreement. The form provided with the appraisal notice will state:

	•	where the form must be returned, where certificates for shares must be deposited, and the date by which such certificates must be deposited;
	•	the date on which the form is due, which will not be fewer than 40 nor more than 60 days after the date the appraisal notice and form are sent, and notice that the stockholder shall have waived the right to demand appraisal with respect to such shares unless the form is received by the specified date;
	•	Ionics’ estimate of the fair value of the shares;
	•	that, if requested in writing, Ionics will provide within 10 days after the date on which all forms are due, the number of stockholders who have returned the forms and the total number of shares owned by such stockholders; and
	•	the date by which the stockholder may withdraw his or her notice of intent to demand appraisal rights, which date will be within 20 days after the date on which all forms are due.

      Perfection of Rights. A stockholder who wishes to exercise appraisal rights shall execute and return the form provided, with all certifications completed, and deposit such stockholder’s share certificates in accordance with the terms of the notice. Once a stockholder deposits his or her share certificates, such stockholder loses all rights as a stockholder unless the stockholder withdraws his or her election in accordance with the withdrawal procedures, which are summarized below. If a stockholder fails to make the certification on the form that such stockholder acquired the shares before the date of the first announcement of the proposed Merger, Ionics may elect to treat those shares as “after-acquired shares,” as described below.

      Withdrawal of Appraisal Rights. A stockholder who has otherwise properly perfected his or her appraisal rights may decline to exercise his or her appraisal rights and withdraw from the appraisal process by notifying Ionics in writing within 20 days after the date on which all forms were due. If the stockholder fails to withdraw from the appraisal process before the expiration of the withdrawal period, such stockholder may not thereafter withdraw without Ionics’ written consent.

      Payment. Within 30 days after the date on which the form described above is due, Ionics will pay in cash to each stockholder who has properly perfected his or her appraisal rights the amount it estimates to be the fair value of their shares, plus interest but subject to any applicable withholding taxes. The payment to each stockholder will be accompanied by:

	•	Ionics’ financial statements;
	•	a statement of Ionics’ estimate of the fair value of the shares, which estimate will equal or exceed the estimate given with the appraisal notice; and
	•	a statement that stockholders may demand further payment if the stockholder is dissatisfied with the payment or offer in accordance with the procedures set forth in Section 13.26 of the MBCA (as described below).

37

Table of Contents

      Notwithstanding the foregoing, in the event that the stockholder is demanding payment for “after-acquired shares,” Ionics may elect to withhold payment from such stockholder. If Ionics elects to withhold payment, it must, within 30 days after the date on which the form described above is due, notify all stockholders who have “after-acquired shares”:

	•	of the information in Ionics’ financial statements;
	•	of Ionics’ estimate of the fair value of the shares, which estimate will equal or exceed the estimate given with the appraisal notice;
	•	that the stockholders may accept the estimate of fair value, plus interest, in full satisfaction of their demands or demand appraisal under Section 13.26 of the MBCA (described below);
	•	that those stockholders who wish to accept Ionics’ offer shall notify Ionics of their acceptance within 30 days after receiving such offer; and
	•	that those stockholders who do not satisfy the requirements for demanding appraisal under Section 13.26 shall be deemed to have accepted Ionics’ offer.

      Within 10 days after receiving the stockholder’s acceptance of the offer, Ionics will pay in cash the amount offered to each stockholder who agreed to accept Ionics’ offer for his or her “after-acquired shares.” Within 40 days after sending the notice to holders of “after-acquired shares”, Ionics must pay in cash the amount offered to each stockholder who does not satisfy the requirements for demanding appraisal under Section 13.26.

      Procedure if Stockholder is Dissatisfied with Payment or Offer. Pursuant to Section 13.26, within 30 days after receipt of payment for a stockholder’s shares, a stockholder who is dissatisfied with the amount of the payment to be received shall notify Ionics in writing of that stockholder’s estimate of the fair value of the shares and demand payment of that estimate plus interest, less any payment previously paid. In addition, within 30 days after receiving Ionics’ offer to pay for a stockholder’s “after-acquired shares”, a stockholder holding “after-acquired shares” who was offered payment (as described above) and who is dissatisfied with that offer shall reject the offer and demand payment of the stockholder’s stated estimate of the fair value of the shares plus interest. A stockholder’s failure to notify Ionics within such 30 day period waives the right to demand payment and shall be entitled only to the payment made or offered as described above.

      Court Proceedings. If a stockholder makes a proper and timely demand for payment that remains unsettled, Ionics will commence an equitable proceeding within 60 days after receiving the payment demand and petition the court to determine the fair value of the shares and accrued interest. If Ionics does not commence the proceeding within the 60-day period, it will pay in cash to each stockholder the amount the stockholder demanded, plus interest.

      Any stockholder wishing to exercise appraisal rights is urged to consult legal counsel before attempting to exercise appraisal rights. Failure to strictly comply with all of the procedures set forth in Part 13 of the MBCA may result in the loss of a stockholder’s statutory appraisal rights.

Delisting and Deregistration of Ionics Common Stock

      If the Merger is completed, Ionics common stock will be delisted from the New York Stock Exchange and will be deregistered under the Securities Exchange Act of 1934.

U.S. Federal Income Tax Treatment

      The following is a discussion of the material federal income tax consequences of the Merger to holders of Ionics common stock. The discussion is based upon the Internal Revenue Code, Treasury regulations, IRS rulings and judicial and administrative decisions in effect as of the date of this Proxy Statement, all of which are subject to change (possibly with retroactive effect) or to different interpretations. The following discussion is limited to the material federal income tax aspects of the

38

Table of Contents

      The following discussion does not address potential foreign, state, local and other tax consequences of the Merger. All stockholders are urged to consult their own tax advisors regarding the federal income tax consequences, as well as the foreign, state and local tax consequences, of the disposition of their shares in the Merger.

      For federal income tax purposes, the Merger will be treated as a taxable sale or exchange of Ionics common stock for cash by each Ionics stockholder. Accordingly, the federal income tax consequences to the Ionics stockholders receiving cash will generally be as follows:

	•	The stockholder will recognize a capital gain or loss upon the disposition of the stockholder’s shares of Ionics common stock pursuant to the Merger.
	•	The capital gain or loss, if any, will be long-term with respect to shares of Ionics common stock that have a holding period for tax purposes in excess of twelve months at the time such Ionics common stock is disposed of.
	•	The amount of capital gain or loss recognized by each stockholder will be measured by the difference between the amount of cash received by the stockholder in connection with the Merger and the stockholder’s adjusted tax basis in the shares of Ionics common stock at the effective time of the Merger.

      Cash payments made pursuant to the Merger will be reported to Ionics stockholders and the Internal Revenue Service to the extent required by the Internal Revenue Code and applicable regulations. These amounts will ordinarily not be subject to withholding of U.S. federal income tax. However, backup withholding of the tax at applicable rates may apply to a stockholder who fails to supply Ionics or the paying agent selected by GE with the stockholder’s taxpayer identification number or has received notice from the Internal Revenue Service of a failure to report all interest and dividends required to be shown on the stockholder’s federal income tax returns, or in certain other cases. Accordingly, each Ionics stockholder will be asked to provide a correct taxpayer identification number on a Substitute Form W-9 which is to be included in the appropriate letter of transmittal for the shares of Ionics common stock. Certain Ionics stockholders will be asked to provide additional tax information in the appropriate letter of transmittal for the shares of Ionics common stock.

      THE FOREGOING DISCUSSION OF CERTAIN MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES IS INCLUDED FOR GENERAL INFORMATIONAL PURPOSES ONLY AND IS NOT INTENDED TO BE, AND SHOULD NOT BE CONSTRUED AS, LEGAL OR TAX ADVICE TO ANY HOLDER OF SHARES OF IONICS COMMON STOCK. IONICS URGES YOU TO CONSULT YOUR OWN TAX ADVISOR TO DETERMINE THE PARTICULAR TAX CONSEQUENCES TO YOU (INCLUDING THE APPLICATION AND EFFECT OF ANY STATE, LOCAL OR FOREIGN INCOME AND OTHER TAX LAWS) OF THE RECEIPT OF CASH IN EXCHANGE FOR SHARES OF IONICS COMMON STOCK PURSUANT TO THE MERGER.

Federal or State Regulatory Filings Required in Connection with the Merger

      United States Antitrust. Under the HSR Act, the Merger may not be completed until notifications have been given and certain information and materials have been furnished to the Antitrust Division of the United States Department of Justice and the Federal Trade Commission and the required waiting period

      Other Jurisdictions. Ionics and GE each conducts operations in a number of foreign countries or jurisdictions where other regulatory approvals may be required or advisable in connection with the consummation of the Merger. Ionics and GE believe that additional filings will be required to be made in Austria, Brazil, Germany, Hungary, Ireland, Italy and South Korea. Under the regulations in Austria, Germany and Ireland, the Merger cannot be completed until the applicable approvals or expiration or termination of any applicable waiting periods have been made or expired or terminated. To date, Ionics and GE have made filings in the following jurisdictions:

Country		Date Filed
Austria			December 17, 2004
Brazil			December 15, 2004
Germany			December 23, 2004
Hungary			December 22, 2004

      Other. Other than those described above and (i) the requirement that Ionics file this Proxy Statement with the SEC and (ii) certain other filings required to be made under the Exchange Act, Ionics is not aware of any federal or state regulatory requirements or approvals that must be complied with or obtained in connection with the Merger.

Rights Plan Amendment

      In December 1987, the Ionics board of directors adopted a Stockholder Rights Plan. On August 19, 1997, the Ionics board of directors renewed the Stockholder Rights Plan (“Renewed Rights Plan”). Under the Renewed Rights Plan, common stock purchase rights (collectively the “Rights” and individually a “Right”) were distributed as a Rights dividend on December 31, 1997 at the rate of one Right for each share of Ionics common stock held as of the close of business on that date. Neither the initial adoption of the Stockholder Rights Plan nor its renewal required stockholder approval.

      The Renewed Rights Plan is designed to prevent an acquirer from gaining control of Ionics without offering a fair price to all of Ionics’ stockholders. The Renewed Rights Plan was not adopted by the Ionics board of directors in response to any specific offer or threat, but rather is intended to protect the interests of stockholders in the event Ionics is confronted in the future with takeover tactics.

      Each Right will entitle holders of Ionics common stock to buy one share of Ionics common stock (or in certain circumstances to receive cash, property or other securities of Ionics) at an exercise price of $175, subject to adjustment. The Rights will be exercisable only after 10 business days following a public announcement that a person or group has acquired more than 15% of Ionics’ common stock (the “Stock Acquisition Date”), or 10 business days after such person or group announces a tender or exchange offer which would result in its ownership of 15% or more of Ionics’ common stock.

      If any person or group becomes the beneficial owner of 15% or more of Ionics’ common stock other than pursuant to a tender or exchange offer for all shares at a price that a majority of the independent directors determines to be fair and otherwise in the best interest of Ionics and its stockholders, then each Right not owned by such person or group will entitle its holder to purchase, at the then current exercise price of the Right, Ionics common stock (or, in certain circumstances as determined by Ionics’ board of directors, a combination of cash, property, common stock or other securities) having a value of twice the Right’s exercise price. In addition, if Ionics is involved in a merger or other business combination with another person in which its common stock is changed or exchanged, or sells or transfers more than 50% of its assets or earning power to another person, each Right that has not previously been exercised will entitle

Table of Contents

      In general, Ionics can redeem the Rights at $0.01 per Right at any time prior to ten days following the Stock Acquisition Date. The Rights will expire on August 19, 2007, unless earlier redeemed or exchanged.

      On November 17, 2003, following approval of such action by Ionics’ board of directors on November 2, 2003, the Renewed Rights Plan was amended to render the Renewed Rights Plan inapplicable to the acquisition by the Ecolochem Holders of shares of Ionics common stock in connection with the acquisition of the Ecolochem Group by Ionics and to certain post-closing transactions effected by the Ecolochem Holders with respect to such shares.

      In connection with the execution and delivery of the Merger Agreement, Ionics’ board of directors approved Amendment No. 2 (the “Rights Amendment”) to the Renewed Rights Plan on November 23, 2004. The Rights Amendment amends certain sections and definitions of the Renewed Rights Plan thereby rendering the Renewed Rights Plan inapplicable to the acquisition by GE or its affiliates of shares of Ionics common stock in connection with the Merger.

      A copy of the Renewed Rights Plan has been filed with the SEC as an exhibit to Ionics’ Current Report on Form 8-K dated August 27, 1997. A copy of Amendment No. 1 to the Renewed Rights Plan has been filed with the SEC as an exhibit to Ionics’ Current Report on Form 8-K filed with the SEC on November 26, 2003. A copy of the Rights Amendment has been filed with the SEC as an exhibit to Ionics’ Current Report on Form 8-K filed with the SEC on November 30, 2004. Copies of the Renewed Rights Plan and Amendments No. 1 and 2 to the Renewed Rights Plan are available free of charge from Ionics.

Anti-Takeover Considerations

      Ionics is subject to the provisions of Chapter 110C of the Massachusetts General Laws, entitled “Regulation of Take-Over Bids in the Acquisition of Corporations.” Under Chapter 110C, no offeror may make a “take-over bid” for the stock of a “target company” without publicly announcing the terms of the bid, filing certain information with the Secretary of the Commonwealth of Massachusetts and the target company and paying a fee to the Secretary of the Commonwealth. The Secretary of the Commonwealth may hold a hearing to determine if adequate disclosure has been made and if the take-over bid is fair. A “target company” is defined as any Massachusetts corporation, or any corporation with its principal place of business in Massachusetts, whose securities are or are to be the subject of a “take-over bid.” Ionics qualifies as a target company. A “take-over bid” is defined as any acquisition or offer to acquire stock of a target company where, after such acquisition, the offeror and its affiliates will be the beneficial owner directly or indirectly of more than 10% of a class of the target company’s stock. However, a “take-over bid” does not include any bid to which the target company’s board of directors consents, if the board of directors has recommended the acceptance of the bid and the terms thereof to the stockholders. For purposes of Chapter 110C, the Ionics board of directors specifically approved and consented to the Merger and recommended the acceptance of the terms thereof to Ionics’ stockholders. Therefore, the Merger is not a “take-over bid” under Chapter 110C.

      Ionics is also subject to the provisions of Chapter 110F of the Massachusetts General Laws, the so-called “Business Combination Statute”. Under Chapter 110F, a Massachusetts corporation with over 200 stockholders, such as Ionics, may not engage in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person becomes an interested stockholder, unless (i) the interested stockholder obtains the approval of the board of directors prior to becoming an interested stockholder, (ii) the interested stockholder acquires 90% of the outstanding voting stock of Ionics (excluding shares held by certain affiliates of Ionics) at the time it becomes an interested stockholder, or (iii) the business combination is approved by both the board of directors and at a meeting of the stockholders by the holders of at least two-thirds of the outstanding voting stock of Ionics (excluding shares held by the interested stockholder). An “interested stockholder” is a person who,

MERGER AGREEMENT AND OTHER RELATED AGREEMENTS

      This section of the Proxy Statement provides a summary of the Merger Agreement, which is the definitive agreement governing the Merger, and certain other agreements relating to the Merger. This summary, however, may not contain all of the information that is important to you. Ionics urges you to carefully read the Merger Agreement, which appears as Annex A to this Proxy Statement.

Merger Consideration

      Upon completion of the Merger, each outstanding share of Ionics common stock will be converted into the right to receive $44.00 in cash, without interest. The price of $44.00 per share was determined through arm’s-length negotiations between Ionics and GE. Upon completion of the Merger, no shares of Ionics common stock will remain outstanding and all shares will automatically be canceled and will cease to exist.

Conversion of Shares; Procedures for Exchange of Certificates

      Your right to receive $44.00 per share in cash, without interest, will arise automatically upon completion of the Merger. Prior to the effective time of the Merger, GE will enter into an agreement with a bank or trust company selected by GE to act as the paying agent under the Merger Agreement. GE will deposit with the paying agent cash amounts sufficient to enable the paying agent to pay the aggregate merger consideration to the holders of shares of Ionics common stock.

      Promptly after the effective time of the Merger, the paying agent will mail to each record holder of shares, a letter of transmittal and instructions for use in surrendering certificates in exchange for the merger consideration. No stockholder should surrender any certificates until the stockholder receives the letter of transmittal and other materials for such surrender. Upon surrender of a stock certificate for cancellation to the paying agent, together with a letter of transmittal, duly executed, the holder of such certificate will be entitled to receive the merger consideration into which the number of shares of common stock previously represented by such stock certificate(s) shall have been converted pursuant to the Merger Agreement, without any interest thereon. The certificates so surrendered will be canceled.

      In the event of a transfer of ownership of shares of common stock which is not registered in Ionics’ transfer records, payment may be made with respect to such shares to the transferee if the stock certificate representing such shares is presented to the paying agent, accompanied by all documents reasonably required by the paying agent to evidence such transfer and to evidence that any applicable stock transfer taxes relating to such transfer have been paid.

      If your stock certificate has been lost, stolen or destroyed, the paying agent will deliver to you the applicable merger consideration for the shares represented by that certificate:

	•	if you make an affidavit claiming such certificate has been lost, stolen or destroyed; and
	•	if requested by GE or the paying agent, you post a bond in a reasonable amount as indemnity against any claim that may be made with respect to that certificate against GE or the paying agent.

      Stockholders should not send their certificates now and should send them only pursuant to instructions set forth in the letter of transmittal to be mailed to stockholders promptly after the effective time of the Merger. In all cases, the merger consideration will be provided only in accordance with the procedures set forth in this Proxy Statement and such letter of transmittal.

Table of Contents

      One hundred and eighty days after the effective time of the Merger, the paying agent will deliver to the surviving corporation any funds made available to the paying agent which have not been disbursed to holders of Ionics stock certificates. Any holders of certificates who have not complied with the above-described procedures to receive payment of the merger consideration during such one hundred and eighty day period may thereafter look only to the surviving corporation for payment of the merger consideration to which they are entitled.

      The cash paid to you upon conversion of your shares of Ionics common stock will be issued in full satisfaction of all rights relating to the shares of Ionics common stock.

Effect on Ionics Stock Options

      The vesting of each stock option to acquire Ionics common stock outstanding at the effective time of the Merger will be accelerated, such that upon the completion of the Merger, all such options will be fully vested and exercisable. Each outstanding stock option to acquire Ionics common stock will be converted at the effective time of the Merger into the right to receive, as soon as practicable (but in no event later than five business days) after the effective time of the Merger, a cash payment equal to the product of (1) the excess of the merger consideration over the per share exercise price of such stock option, multiplied by (2) the aggregate number of shares of common stock then subject to such stock option, whether or not then vested or exercisable.

Effective Time of the Merger

      The Merger will become effective upon the filing of articles of merger with the Massachusetts Secretary of State or at such later time as is agreed upon by GE and Ionics and specified in the articles of merger. The filing of the articles of merger will occur on the closing date (the “Closing Date”). Subject to the terms and conditions of the Merger Agreement and in accordance with Massachusetts law, at the effective time of the Merger, Merger Sub, an indirect wholly-owned subsidiary of GE and a party to the Merger Agreement, will merge with and into Ionics. Ionics will survive the Merger as an indirect wholly-owned Massachusetts subsidiary of GE. If the Merger Agreement is approved by Ionics’ stockholders, the Merger will be completed as soon as all of the other conditions to the Merger set forth in the Merger Agreement have been satisfied or waived by GE or Ionics, as applicable. These conditions are described below under “Merger Agreement and Other Related Agreements — Conditions to Closing.”

Representations and Warranties

      The Merger Agreement contains representations and warranties of each party to the agreement. These representations and warranties will expire upon completion of the Merger.

      The Merger Agreement contains customary representations and warranties of Ionics as to, among other things:

	•	Ionics’ organization, good standing and corporate power;
	•	Ionics’ capitalization;
	•	authorization, noncontravention, voting requirements;
	•	governmental approvals;
	•	Ionics’ SEC documents; the absence of undisclosed liabilities;
	•	absence of certain changes or events;
	•	legal proceedings;
	•	compliance with laws; permits;

Covenants of the Parties

	Conduct of Ionics’ Business

      Ionics agreed in the Merger Agreement that, unless GE otherwise consents in writing, Ionics will carry on its business in the ordinary course, consistent with past practice, comply in all material respects with all applicable laws and the requirements of all material contracts and permits, make all voluntary disclosures deemed appropriate to governmental authorities and use commercially reasonable efforts to (i) maintain and preserve intact Ionics’ business organization and the goodwill of those having significant business relationships with Ionics, (ii) retain the services of its present officers and key employees and (iii) keep in full force and effect all material insurance policies maintained by Ionics and its subsidiaries, other than changes to such policies made in the ordinary course of business consistent with past practice.

No-Shop Provisions

      Ionics has agreed, prior to the Merger becoming effective, to certain limitations on Ionics’ ability to take action with respect to other potential acquisition transactions. Ionics has agreed to terminate any discussions or negotiations with any person with respect to a Takeover Proposal (as defined below). In addition, except as set forth below, Ionics has agreed to not directly or indirectly:

	•	solicit, initiate or knowingly facilitate or encourage (including by way of furnishing information) any inquiries or proposals that constitute, or may reasonably be expected to lead to, any Takeover Proposal;
	•	participate in any discussions or negotiations with any third party regarding any Takeover Proposal;
	•	enter into any agreement related to any Takeover Proposal;
	•	withdraw or modify, or propose publicly to withdraw or modify, in a manner adverse to GE, the board of directors’ recommendation that Ionics’ stockholders approve the Merger Agreement;
	•	approve or recommend, or propose publicly to approve or recommend, any Takeover Proposal; or
	•	approve or recommend or propose publicly to approve or recommend, or cause or authorize Ionics or any of its subsidiaries to enter into any letter of intent, agreement in principle, memorandum of understanding, merger, acquisition, purchase or joint venture agreement or other agreement related to any Takeover Proposal.

      Notwithstanding these Limitations:

	•	if after November 24, 2004, Ionics’ board of directors receives an unsolicited, bona fide written Takeover Proposal that was made after November 24, 2004 in circumstances not involving a breach of the Merger Agreement and the board of directors determines in good faith that such Takeover

Table of Contents

		Proposal is reasonably likely to result in a Superior Proposal (as defined below) and with respect to which the board determines in good faith, after considering applicable provisions of state law and after consulting with and receiving the advice of outside counsel, that the failure to take such action would be inconsistent with its fiduciary duties to Ionics’ stockholders under Massachusetts law, then Ionics may (but only prior to obtaining stockholder approval of the Merger), after providing GE not less than 24 hours written notice of Ionics’ intention to take such actions: (1) furnish information to the person making such Takeover Proposal, but only after such person enters into a customary confidentiality agreement with Ionics that is no less favorable in any material respect to Ionics than its confidentiality agreement with GE, (2) participate in discussions and negotiations with such person regarding such Takeover Proposal and (3) enter into the confidentiality agreement contemplated by (1) above;
	•	Ionics’ board of directors may withdraw or modify its recommendation that its stockholders approve the Merger Agreement, or recommend a Takeover Proposal, if the board determines in good faith, after reviewing applicable provisions of Massachusetts law and after consulting with and receiving advice from outside counsel, that the failure to make such withdrawal, modification or recommendation would be inconsistent with its fiduciary duties to Ionics’ stockholders under Massachusetts law; and
	•	if Ionics’ board of directors receives an unsolicited, bona fide written Takeover Proposal that was made in circumstances not involving a breach of the Merger Agreement and that the board determines in good faith constitutes a Superior Proposal, the board of directors may, in response to such Superior Proposal and within a set timeframe, cause Ionics to enter into a definitive agreement with respect to such Superior Proposal; however, in such circumstances, Ionics would be required to pay a $33,000,000 termination fee to GE as described below under “Merger Agreement and Other Related Agreements — Fees and Expenses.”

      Prior to responding to an unsolicited Takeover Proposal, Ionics must give GE notice of the Takeover Proposal. Ionics must also provide GE with copies of any written materials received from or on behalf of the person making the Takeover Proposal and shall keep GE fully informed of all material developments regarding the Takeover Proposal. Ionics must furnish GE with simultaneous copies of any non-public information that Ionics provides to the person that made such unsolicited Takeover Proposal.

      Under the Merger Agreement, “Takeover Proposal” means any inquiry, proposal or offer from anyone (other than GE and its subsidiaries) or any group relating to any:

	•	direct or indirect acquisition (whether in a single transaction or a series of related transactions) of Ionics’ assets and those of its subsidiaries equal to 15% or more of Ionics’ consolidated assets or to which 15% or more of Ionics’ consolidated revenues on a consolidated basis for the then preceding four completed and publicly reported calendar quarters are attributable;
	•	direct or indirect acquisition (whether in a single transaction or a series of related transactions) of 15% or more of any class of Ionics’ equity securities;
	•	tender offer or exchange offer that if completed would result in any person or group beneficially owning 15% or more of any class of Ionics’ equity securities; or
	•	merger, consolidation, share exchange, business combination, recapitalization, liquidation, or similar transaction involving Ionics or any of its subsidiaries.

      Under the Merger Agreement, “Superior Proposal” means a Takeover Proposal to acquire, directly or indirectly, for consideration consisting of cash and/or securities, all of Ionics’ equity securities or all or substantially all of Ionics’ assets and those of its subsidiaries on a consolidated basis, made by a third party, which is not subject to a financing contingency and which is otherwise on terms and conditions which Ionics’ board of directors determines in its good faith judgment (after consultation with a financial advisor of national reputation) to be more favorable to Ionics’ stockholders from a financial point of view than the Merger, taking into account at the time of determination any changes to the Merger Agreement

	•	by either Ionics or GE if:

	•	the Merger is not completed by August 1, 2005; provided a party may not so terminate the Merger Agreement if the Merger shall not have been completed primarily due to a party’s breach or failure to perform any of its representations, warranties, covenants or agreements under the Merger Agreement;

Voting Agreement

      In connection with the execution of the Merger Agreement and with the consent of Ionics’ board of directors (which was required pursuant to that certain Stockholders Agreement dated as of February 13, 2004 by and among Ionics and the Ecolochem Holders), GE and the Ecolochem Holders (who collectively own a total of 4,402,646 shares of Ionics common stock, or approximately 19.2% of the outstanding shares of Ionics common stock) entered into a Voting Agreement dated as of November 24, 2004 (the “Voting Agreement”) pursuant to which the Ecolochem Holders:

	•	agreed to vote their shares of Ionics common stock (a) in favor of the approval of the Merger Agreement and the transactions contemplated thereunder, (b) against any action or agreement that would result in a breach of any representation, warranty, covenant or other obligation of Ionics in the Merger Agreement, (c) against any other merger agreement or merger, consolidation, combination, sale of substantial assets, reorganization, recapitalization, dissolution, liquidation or winding up of Ionics or any other Takeover Proposal and (d) against any agreement, amendment of Ionics articles of organization or bylaws or other action that could be reasonably expected to prevent, impede, interfere with, delay, postpone or discourage the consummation of the Merger;
	•	appointed, to secure the performance by the Ecolochem Holders of the Voting Agreement, GE and its designees as the Ecolochem Holders’ proxy and attorney-in-fact to vote their shares of Ionics common stock (a) in favor of the approval of the Merger Agreement and the approval of the transactions contemplated thereunder, (b) against any action or agreement that would result in a breach of any representation, warranty, covenant, agreement or other obligation of Ionics under the Merger Agreement, (c) against any Takeover Proposal and (d) against any agreement, amendment of Ionics’ articles of organization or bylaws or other action that is intended or could reasonably be expected to prevent, impede, interfere with, delay, postpone or discourage the consummation of the Merger;
	•	agreed not to (a) other than pursuant to the Merger, sell, transfer (including by operation of law), give, pledge, encumber, assign or otherwise dispose of (collectively, “Transfer”), or enter into any contract, option or other arrangement (including any profit sharing arrangement) or understanding with respect to the Transfer of, any shares of Ionics common stock owned by any Ecolochem Holder (or any interest therein), (ii) deposit any shares of Ionics common stock owned by any Ecolochem Holder into a voting trust or grant any proxies or enter into a voting agreement, power of attorney or voting trust with respect to any shares of Ionics common stock owned by an Ecolochem Holder, (iii) commit to do any of the foregoing or (iv) take any action that would make any representation or warranty of an Ecolochem Holder set forth in the Voting Agreement untrue or incorrect in any material respect or have the effect of preventing, disabling or delaying an Ecolochem Holder from performing any of its obligations under the Voting Agreement, subject to certain exceptions;

Table of Contents

	•	made certain representations and warranties.

      In the Voting Agreement, GE:

	•	made certain representations and warranties; and
	•	agreed that after the completion of the Merger, it would amend the definition of the “Cut-Off Time” as used in the Escrow Agreement, such that the Cut-Off Time shall become the effective time of the completion of the Merger. While Ionics could still make indemnification claims against the Ecolochem Holders, the effect of this amendment would be to shorten the deadline for Ionics to recover for such claims from the Escrowed Funds from February 13, 2006 to the effective time of the completion of the Merger. Mr. Lyman Dickerson, a director and executive officer of Ionics, and persons related to him beneficially own the cash and shares of Ionics common stock held in escrow and may be deemed to benefit from shortening the deadline for recovery of indemnification claims from the escrowed amounts and the resulting release of the cash and Ionics common stock from escrow.

      A copy of the Voting Agreement is attached as Annex C to this Proxy Statement.

Stockholder Proposals

      Ionics’ 2005 Annual Meeting of Stockholders is presently scheduled to be held on May 3, 2005. The 2005 Annual Meeting of Stockholders will only be held if the Merger is not completed. Proposals of stockholders intended to be presented at the 2005 Annual Meeting of Stockholders were due by January 2, 2005, for inclusion in Ionics’ proxy statement and proxy for that meeting, except that if the date of the 2005 Annual Meeting of Stockholders is changed by more than 30 calendar days from the presently expected date, Ionics must receive such proposal within a reasonable time before the Ionics board of directors makes its proxy solicitation.

      Under Ionics’ By-laws, stockholder proposals submitted for action at the 2005 Annual Meeting of Stockholders but not proposed for inclusion in Ionics’ proxy statement must be given to the Secretary of Ionics not less than 80 nor more than 120 days prior to the anniversary date of the immediately preceding Annual Meeting. Therefore, stockholders who wish to make a proposal at the 2005 Annual Meeting of Stockholders (other than one that will be included in Ionics’ proxy materials) must notify Ionics no later than February 14, 2005 and no earlier than January 5, 2005. In the case of a Special Meeting of stockholders, or in the event the Annual Meeting is called for a date more than 60 days prior to the anniversary date, a stockholder must give such notice no later than 20 days following the date on which notice of the meeting date was mailed or publicly disclosed. Stockholder proposals for nomination of candidates to the Ionics board of directors are subject to similar time constraints. Articles V and VII of Ionics’ By-laws contain certain requirements for the content of such proposals.

EXPENSES AND SOLICITATION

      The cost of solicitation of proxies will be borne by Ionics. In addition to soliciting stockholders by mail, certain of Ionics’ directors, officers and employees, without additional remuneration, may solicit proxies in person or by telephone or other means of electronic communication. Ionics will not pay these individuals for their solicitation activity but will reimburse them for their reasonable out-of-pocket expenses. Brokers and other custodians, nominees and fiduciaries will be requested to forward proxy-soliciting material to the owners of stock held in their names, and Ionics will reimburse such brokers and other custodians, nominees and fiduciaries for their reasonable out-of-pocket costs. Solicitation by directors, officers and employees of Ionics may also be made of some stockholders in person or by mail, telephone or other means of electronic communication following the original solicitation. Ionics has retained an independent proxy solicitation firm, Georgeson Shareholder, to assist in soliciting proxies. Ionics has agreed to pay Georgeson Shareholder fees for proxy solicitation services in the amount of $15,000 in fixed fees plus additional fees based on the number of soliciting calls made to Ionics’ stockholders and the number of votes received as a result of such calls, plus its expenses incurred in performing such services.

      (b) Payment Procedures. Promptly (but in any event within five (5) Business Days) after the Effective Time, the Paying Agent shall mail to each holder of record of a Certificate (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Paying Agent, and which shall be in such form and shall have such other provisions as Parent may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration. Upon surrender of a Certificate for cancellation to the Paying Agent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions (and such other customary documents as may reasonably be required by the Paying Agent), the holder of such Certificate shall be entitled to receive in exchange therefor the amount of cash into which the shares of Company Common Stock formerly represented by such Certificate shall have been converted pursuant to Section 2.1(c), and the Certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of shares of Company Common Stock that is not registered in the transfer records of the Company, the proper amount of cash may be paid in exchange therefor to a Person other than the Person in whose name the Certificate so surrendered is registered if such Certificate shall be properly endorsed or shall otherwise be in proper form for transfer and the Person requesting such payment shall pay any transfer and other Taxes required by reason of the payment to a Person other than the registered holder of such Certificate or establish to the satisfaction of the Surviving Corporation that such Tax either has been paid or is not applicable. Until surrendered as contemplated by this Section 2.2(b), each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration. No interest will be paid or will accrue on the cash payable upon surrender of any Certificate.

      (c) Transfer Books; No Further Ownership Rights in Company Stock. All cash paid upon the surrender of Certificates in accordance with the terms of this Article II shall be deemed to have been paid in full satisfaction of all rights pertaining to the shares of Company Common Stock previously represented by such Certificates. At the close of business on the day on which the Effective Time occurs, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Company Common Stock that were outstanding immediately prior to the Effective Time. Subject to Section 2.2(e), if, at any time after the Effective Time, Certificates are presented to the Surviving Corporation or the Paying Agent for any reason, they shall be canceled and exchanged as provided in this Article II.

      (d) Lost, Stolen or Destroyed Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such Person of a bond, in such reasonable amount as Parent may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent will pay the Merger Consideration to such Person in exchange for such lost, stolen or destroyed Certificate.

      (e) Termination of Fund. Any portion of the Payment Fund (including the proceeds of any investments thereof) that remains undistributed to the holders of the Certificates for 180 days after the Effective Time shall be delivered by the Paying Agent to the Surviving Corporation upon demand. Any holders of Certificates who have not theretofore complied with this Article II shall thereafter look only to the Surviving Corporation for payment of the Merger Consideration.

      (f) No Liability. Notwithstanding any provision of this Agreement to the contrary, none of Parent, the Surviving Corporation or the Paying Agent shall be liable to any Person for any amount properly paid from the Payment Fund or delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

      (g) Investment of Payment Fund. The Paying Agent shall invest the Payment Fund as directed by Parent. Any interest and other income resulting from such investment shall be the property of, and shall be paid promptly to, Parent.

      SECTION 2.3     Company Stock Options.

      (a) To the extent not inconsistent with contractual rights, at the Effective Time, by virtue of the Merger and without any action on the part of the holder of any Option, each Option outstanding immediately prior to the Effective Time shall be cancelled and terminated or converted into the right to receive a cash amount equal to the Option Consideration for each share of Company Common Stock then subject to the Option. Prior to the Effective Time, the Company shall take all actions necessary to provide that each Option outstanding immediately prior to the Effective Time (whether or not then vested or exercisable) shall be cancelled and terminated and converted at the Effective Time into the right to receive a cash amount equal to the Option Consideration for each share of Company Common Stock then subject to the Option. Except as otherwise provided below, the Option Consideration shall be paid as soon (but in any event within five (5) business days) after the Closing Date as shall be practicable. Prior to the Effective Time, the Company shall make any amendments to the terms of the Company Stock Plans, and to the terms of any agreement or instrument evidencing the grant of any Options issued other than pursuant to the Company Stock Plans, and use its best efforts to obtain any consents from holders of Options that, in each case, are necessary to give effect to the transactions contemplated by this Section 2.3 and, notwithstanding anything to the contrary, payment may be withheld in respect of any Option until any necessary consents are obtained. Without limiting the foregoing, the Company shall take all actions necessary to ensure that the Company will not at the Effective Time be bound by any options, SARs, warrants or other rights or agreements which would entitle any Person, other than Parent and its Subsidiaries, to own any capital stock of the Surviving Corporation or to receive any payment in respect thereof (other than pursuant to this Section 2.3). Prior to the Effective Time, the Company shall take all actions necessary to terminate all its Company Stock Plans, such termination to be effective at or before the Effective Time. For purposes of this Agreement, “Option Consideration” means, with respect to any share of Company Common Stock issuable under a particular Option, an amount equal to the excess, if any, of (i) the Merger Consideration per share of Company Common Stock over (ii) the exercise price payable in respect of such share of Company Common Stock issuable under such Option.

      (b) The Company shall take such steps as may be reasonably requested by any party hereto to cause dispositions of Company equity securities (including derivative securities) pursuant to the transactions contemplated by this Agreement by each individual who is a director or officer of the Company to be exempt under Rule 16b-3 promulgated under the Exchange Act in accordance with that certain No-Action Letter dated January 12, 1999 issued by the Securities and Exchange Commission (the “SEC”) regarding such matters.

      SECTION 2.4     Withholding Taxes. Parent, the Surviving Corporation and the Paying Agent shall be entitled to deduct and withhold from the consideration otherwise payable to a holder of shares of Company Common Stock or Options pursuant to this Agreement such amounts as may be required to be deducted or withheld with respect to the making of such payment under the Code, or under any provision of state, local or foreign Tax Law. To the extent that amounts are so deducted and withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person in respect of which such deduction and withholding was made.

      SECTION 2.5     Adjustments. If during the period between the date of this Agreement and the Effective Time, any change in the outstanding shares of Company Common Stock, or securities convertible or exchangeable into or exercisable for shares of Company Common Stock, shall occur by reason of any reclassification, recapitalization, stock split or combination, exchange or readjustment of shares of Company Common Stock, or any similar transaction, or any stock dividend thereon with a record date during such period, the Merger Consideration shall be appropriately adjusted to reflect such change.

Neither the Company nor any of its Subsidiaries is in material breach or default, and neither the Company nor any of its Subsidiaries have taken any action or failed to take any action which, with notice or the lapse of time, would constitute such a breach or default, or permit termination or modification of any of the Policies. No notice of cancellation or termination has been received by the Company with respect to any such Policy. With respect to each of the legal proceedings set forth in the Company SEC Documents, no carrier of any Policy has asserted any denial of coverage other than the issuance of customary reservation of rights letters issued by such carriers in connection with the filing of any claims.

      SECTION 3.18     Opinion of Financial Advisor. The Board of Directors of the Company has received the opinions of Goldman, Sachs & Co. (“Goldman Sachs”) and UBS Securities LLC (“UBS”), each dated as of the date of this Agreement, to the effect that, as of such date, and subject to the various assumptions and qualifications set forth therein, the consideration to be received in the Merger by the stockholders of the Company is fair from a financial point of view to such stockholders (the “Fairness Opinions”).

The action of the Company’s Board of Directors in adopting and approving this Agreement, the Merger and the other Transactions has rendered Sections 110C, 110D and 110F of the Massachusetts Corporation-Related Laws inapplicable to this Agreement, the Voting Agreement and the Transactions.

      SECTION 3.21     Company Rights Plan. The Company has taken all actions necessary to (a) render the Renewed Rights Agreement, dated as of August 19, 1997, between the Company and Equiserve Trust Company, as rights agent (as amended, the “Company Rights Agreement”), inapplicable to this Agreement, the Voting Agreement and the Transactions, (b) ensure that (i) none of Parent, Merger Sub or any other Subsidiary of Parent is an Acquiring Person (as defined in the Company Rights Agreement) pursuant to the Company Rights Agreement as a result of this Agreement, the Voting Agreement or the Transactions contemplated hereby and (ii) a Distribution Date, a Triggering Event or a Stock Acquisition Date (as such terms are defined in the Company Rights Agreement) does not occur, in the case of clauses (i) and (ii), solely by reason of the execution of this Agreement or the Voting Agreement or the consummation of the Transactions, and (c) provide that the Final Expiration Date (as defined in the Company Rights Agreement) shall occur immediately prior to the Effective Time.

      (c) Except as expressly permitted by this Section 5.3(c), neither the Board of Directors of the Company nor any committee thereof shall (i)(A) withdraw or modify, or propose publicly to withdraw or modify, in a manner adverse to Parent, the Company Board Recommendation or (B) approve or recommend, or propose publicly to approve or recommend, any Takeover Proposal or (ii) approve or recommend, or propose publicly to approve or recommend, or cause or authorize the Company or any of its Subsidiaries to enter into, any letter of intent, agreement in principle, memorandum of understanding, merger, acquisition, purchase or joint venture agreement or other agreement related to any Takeover Proposal (other than a confidentiality agreement in accordance with Section 5.3(a)) (each, a “Company Acquisition Agreement”). Notwithstanding the foregoing or any other provision of this Agreement, (x) the Board of Directors of the Company may withdraw or modify the Company Board Recommendation, or recommend a Takeover Proposal, if such Board determines in good faith, after reviewing applicable provisions of Massachusetts Law and after consulting with and receiving advice from outside counsel, that the failure to make such withdrawal, modification or recommendation would be inconsistent with its fiduciary duties to the Company’s stockholders under Massachusetts Law and (y) if the Board of Directors of the Company receives an unsolicited, bona fide written Takeover Proposal that was made in circumstances not involving a breach of this Agreement (other than immaterial breaches that have not directly or indirectly resulted in the making of a Takeover Proposal) and that such Board determines in good faith constitutes a Superior Proposal, the Board of Directors of the Company may, in response to such Superior Proposal and within 48 hours after the expiration of the three business day period described below, cause the Company to enter into a definitive agreement with respect to such Superior Proposal but only if the Company shall have concurrently with entering into such definitive agreement terminated this Agreement pursuant to Section 7.1(d)(ii) and prior thereto or concurrently therewith paid the

      (d) For purposes of this Agreement:

	“Takeover Proposal” means any inquiry, proposal or offer from any Person or “group” (as defined in Section 13(d) of the Exchange Act), other than Parent and its Subsidiaries, relating to any (A) direct or indirect acquisition (whether in a single transaction or a series of related transactions) of assets of the Company and its Subsidiaries (including securities of Subsidiaries) equal to 15% or more of the Company’s consolidated assets or to which 15% or more of the Company’s consolidated revenues on a consolidated basis for the then preceding four completed and publicly reported calendar quarters are attributable, (B) direct or indirect acquisition (whether in a single transaction or a series of related transactions) of 15% or more of any class of equity securities of the Company, (C) tender offer or exchange offer that if consummated would result in any Person or “group” (as defined in Section 13(d) of the Exchange Act) beneficially owning 15% or more of any class of equity securities of the Company or (D) merger, consolidation, share exchange, business combination, recapitalization, liquidation, dissolution or similar transaction involving the Company or any of its Subsidiaries; in each case, other than the Transactions.
	“Superior Proposal” means a Takeover Proposal to acquire, directly or indirectly, for consideration consisting of cash and/or securities, all of the equity securities of the Company or all or substantially all of the assets of the Company and its Subsidiaries on a consolidated basis, made by a third party, which is not subject to a financing contingency and which is otherwise on terms and conditions which the Board of Directors of the Company determines in its good faith judgment (after consultation with a financial advisor of national reputation) to be more favorable to the Company’s stockholders from a financial point of view than the Merger and the other Transactions, taking into account at the time of determination any changes to the terms of this Agreement that as of that time had been proposed by Parent in writing (and not withdrawn) and the ability of the Person making such proposal to consummate the transactions contemplated by such proposal (based upon, among other things, the availability of financing and the expectation of obtaining required approvals).

      (e) Nothing in this Section 5.3 shall prohibit the Board of Directors of the Company from taking and disclosing to the Company’s stockholders a position contemplated by Rule 14e-2(a), Rule 14d-9 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act if such Board of Directors determines in good faith, after consultation with outside counsel, that failure to so disclose such position would constitute a violation of applicable Law; provided, however, that if such disclosure has the effect of withdrawing or modifying the Company Board Recommendation in a manner adverse to Parent or the approval of this Agreement by the Board of Directors of the Company, Parent shall have the right to terminate this Agreement to the extent set forth in Section 7.1(c)(iii) of this Agreement; provided further, however, that in no event shall the Company or its Board of Directors or any committee thereof take, or agree or resolve to take, any action prohibited by Section 5.3(c).

November 24, 2004

Board of Directors

Madame and Gentlemen:

      You have requested our opinion as to the fairness from a financial point of view to the holders of the outstanding shares of common stock, par value $1.00 per share (the “Shares”), of Ionics, Incorporated (the “Company”) of the $44.00 per Share in cash to be received by such holders pursuant to the Agreement and Plan of Merger, dated as of November 24, 2004 (the “Agreement”), among General Electric Company (“GE”), Triton Acquisition Corp., a wholly-owned subsidiary of GE, and the Company.

      Goldman, Sachs & Co. and its affiliates, as part of their investment banking business, are continually engaged in performing financial analyses with respect to businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and other transactions as well as for estate, corporate and other purposes. We have acted as financial advisor to the Company in connection with, and have participated in certain of the negotiations leading to, the transaction contemplated by the Agreement (the “Transaction”). We expect to receive fees for our services in connection with the Transaction, all of which are contingent upon consummation of the Transaction, and the Company has agreed to reimburse our expenses and indemnify us against certain liabilities arising out of our engagement. In addition, we have provided certain investment banking and other services to the Company from time to time, including having acted as financial advisor to the Company in connection with its acquisition of Ecolochem, Inc. and its affiliates in February 2004. We have provided certain investment banking and other services to GE and its affiliates from time to time, including having acted as agent in connection with GE’s medium term note program; having acted as financial advisor to GE in connection with its acquisition of Kretztechnik AG in October 2001, its acquisition of Interlogix, Inc. in February 2002, its acquisition of Telemundo Communications Group, Inc. in April 2002, its acquisition of Bravo in December 2002, its acquisition of Instrumentarium Corporation in October 2003, its acquisition of Amersham plc in April 2004 and its acquisition of ChevronTexaco Worldwide Gasification Technology Inc. in June 2004; having acted as joint lead manager of the initial public offering of common stock of Genworth Financial, Inc., a subsidiary of GE, and related financings in May 2004; having acted as joint bookrunning manager of an offering of GE’s common stock in May 2004; having acted as financial advisor to GE Capital Corporation in connection with its acquisition of Mellon U.S. Leasing and Mellon Leasing-Manufacturer and Dealer Services in June 2001, its acquisition of Franchise Finance Corporation of America in August 2001 and its sale of Financial Guarantee Insurance Company in December 2003; and having acted as underwriter in connection with a number of other financing transactions for GE and its affiliates.

      In connection with this opinion, we have reviewed, among other things, the Agreement; annual reports to stockholders and Annual Reports on Form 10-K of the Company for the five fiscal years ended December 31, 2003; certain interim reports to stockholders and Quarterly Reports on Form 10-Q of the Company; certain other communications from the Company to its stockholders; and certain internal financial analyses and forecasts for the Company prepared by its management. We also have held discussions with members of the senior management of the Company regarding their assessment of the past and current business operations, financial condition and future prospects of the Company. In addition, we have reviewed the reported price and trading activity for the Shares, compared certain financial and stock market information for the Company with similar information for certain other companies the securities of which are publicly traded, reviewed the financial terms of certain recent business combinations in the water technology industry specifically and in other industries generally and performed such other studies and analyses, and considered such other factors, as we considered appropriate.

      We have relied upon the accuracy and completeness of all of the financial, accounting, legal, tax and other information discussed with or reviewed by us and have assumed such accuracy and completeness for purposes of rendering this opinion. In that regard, we have assumed with your consent that the internal financial forecasts prepared by the management of the Company have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the Company. In addition, we have not made an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or off-balance-sheet assets and liabilities) of the Company or any of its subsidiaries and we have not been furnished with any such evaluation or appraisal. We were not requested to solicit, and did not solicit, interest from other parties with respect to an acquisition of or other business combination with the Company. Our opinion does not address the underlying business decision of the Company to engage in the Transaction. Our advisory services and the opinion expressed herein are provided for the information and assistance of the Board of Directors of the Company in connection with its consideration of the Transaction and such opinion does not constitute a recommendation as to how any holder of Shares should vote with respect to the Transaction.

      Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the $44.00 per Share in cash to be received by the holders of Shares pursuant to the Agreement is fair from a financial point of view to such holders.

	Very truly yours,

ANNEX B-2

[Letterhead of UBS Securities LLC]

November 24, 2004

The Board of Directors

Dear Members of the Board:

      We understand that Ionics, Incorporated, a Massachusetts corporation (the “Company”), is considering a transaction whereby Triton Acquisition Corp., a Massachusetts corporation (“Merger Sub”) and a wholly owned subsidiary of General Electric Company, a New York corporation (“Parent”), will be merged with and into the Company (the “Merger”). Pursuant to the terms of the Agreement and Plan of Merger dated as of November 24, 2004 (the “Merger Agreement”), among Parent, Merger Sub and the Company, each issued and outstanding share of common stock, par value $1.00 per share (the “Shares”), of the Company will be converted into the right to receive $44.00 in cash (the “Consideration”). The terms and conditions of the Merger are more fully set forth in the Merger Agreement.

      You have requested our opinion as to the fairness from a financial point of view to the holders of the Shares of the Consideration to be received by such holders in the Merger.

      UBS Securities LLC (“UBS”) has acted as financial advisor to the Board of Directors of the Company in connection with the Merger and will receive a fee for its services which is contingent upon consummation of the Merger. In the past, UBS and its predecessors and affiliates have provided investment banking services to the Company and Parent and received customary compensation for the rendering of such services. UBS and its affiliates currently are lead arranger, administrative agent, collateral agent and swingline lender under the Company’s credit facility, dated February 13, 2004, and UBS entered into an interest rate swap transaction with the Company in March 2004. UBS and its predecessors and affiliates acted as joint and sole book-running manager, co-manager and agent for various securities offerings of Parent and GE Capital Corporation, a subsidiary of Parent, in the past two years; as senior co-manager for the initial public offering of common stock of Genworth Financial, Inc., a subsidiary of Parent, in May 2004; as senior co-manager for the public offering of convertible notes of Genworth Financial, Inc. in May 2004; as financial advisor to Parent in connection with the sale of Garrett Aviation Services to the Carlyle Group in July 2004; and currently provide extensions of credit to Parent and its affiliates in connection with certain credit facilities. In the ordinary course of business, UBS, its successors and affiliates have traded, and may in the future trade, securities of the Company or Parent and their respective affiliates for their own accounts and the accounts of their customers and, accordingly, may at any time hold a long or short position in such securities.

      Our opinion does not address the relative merits of the Merger as compared to other business strategies or transactions that might be available to the Company or the Company’s underlying business decision to effect the Merger, nor does our opinion constitute a recommendation to any shareholder of the Company as to how such shareholder should vote with respect to the Merger. We have not been asked to, nor do we, offer any opinion as to any terms of the Merger Agreement or related documents and the obligations thereunder, or the form of the Merger. In rendering this opinion, we have assumed, with your consent, that Parent, Merger Sub and the Company will comply with all the material terms of the Merger Agreement. We have not been authorized to solicit, and have not solicited, indications of interest in a business combination with the Company from any party.

      In arriving at our opinion, we have, among other things: (i) reviewed certain publicly available business and historical financial information and other data relating to the Company; (ii) reviewed current

      In connection with our review, with your consent, we have not assumed any responsibility for independent verification of any of the information reviewed by us for the purpose of this opinion and have, with your consent, relied on such information being complete and accurate in all material respects. In addition, at your direction, we have not made any independent evaluation or appraisal of any of the assets or liabilities (contingent or otherwise) of the Company, nor have we been furnished with any such evaluation or appraisal. With respect to the financial forecasts and estimates referred to above, we have assumed, at your direction, that they have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of the Company as to the future performance of the Company. We have also assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the Merger will be obtained without any material adverse effect on the Company or the Merger. Our opinion is necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to us as of, the date hereof.

      Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Consideration to be received by the holders of the Shares in the Merger is fair, from a financial point of view, to such holders.

	Very truly yours,

In furtherance of the foregoing, such Stockholder agrees that any Transfer in violation of this Agreement shall be void and of no force or effect.

      2. Representations and Warranties of Stockholders. Each Stockholder hereby represents and warrants to Parent, severally and not jointly, as follows:

      (a) Authority. Each Stockholder has all necessary power and authority to execute and deliver this Agreement and to consummate the transactions contemplated hereby. The execution, delivery and performance by such Stockholder of this Agreement, and the consummation of the transactions contemplated hereby, have been duly authorized and approved by all necessary action on the part of such Stockholder and no further action on the part of such Stockholder is necessary to authorize the execution, delivery and performance by such Stockholder of this Agreement and the consummation by such Stockholder of the transactions contemplated hereby. This Agreement has been duly executed and delivered by such Stockholder and, assuming due and valid authorization, execution and delivery hereof by Parent, constitutes a valid and binding obligation of such Stockholder, enforceable against such Stockholder in accordance with its terms, subject to the Bankruptcy and Equity Exception. Such Stockholder does not require the consent of any of its beneficiaries to the execution and delivery of this Agreement or to the consummation of the transactions contemplated hereby.

      (b) Consents and Approvals; No Violations. Except for filings under the Exchange Act, to such Stockholder’s knowledge, no consents or approvals of, or filings, declarations or registrations with, any Governmental Authority are necessary for the consummation by such Stockholder of the transactions contemplated by this Agreement, other than such other consents, approvals, filings, declarations or registrations that, if not obtained, made or given, would not, individually or in the aggregate, reasonably be expected to prevent or materially delay the performance by such Stockholder of any of its obligations under this Agreement. Neither the execution and delivery of this Agreement by such Stockholder, nor the consummation by such Stockholder of the transactions contemplated hereby, nor compliance by such Stockholder with any of the terms or provisions hereof, will, (A) conflict with or violate any provision of the trust agreement of such Stockholder or (B) assuming that the authorizations, consents, approvals and filings referred to in the preceding sentence are obtained and made, (x) violate any judgment or injunction of any Governmental Authority applicable to such Stockholder or any of its properties or assets or, to such

      (b) Authority; Noncontravention.

The execution, delivery and performance by Parent of this Agreement, and the consummation by Parent of the transactions contemplated hereby, have been duly authorized and approved by its Board of Directors and no other corporate action on the part of Parent is necessary to authorize the execution, delivery and performance by Parent of this Agreement and the consummation by it of the transactions contemplated hereby. This Agreement has been duly executed and delivered by Parent and, assuming due authorization, execution and delivery hereof by each Stockholder, constitutes a legal, valid and binding obligation of Parent, enforceable against it in accordance with its terms, subject to the Bankruptcy and Equity Exception. (2) Neither the execution and delivery of this Agreement by Parent, nor the consummation by Parent of the transactions contemplated hereby, nor compliance by Parent with any of the terms or provisions hereof, will (i) conflict with or violate any provision of the certificate of incorporation or bylaws of Parent or (ii) assuming that the authorizations, consents and approvals referred to in Section 3(c) are obtained and the filings referred to in Section 3(c) are made, (x) violate any Law, judgment, writ or injunction of any Governmental Authority applicable to Parent or any of its Subsidiaries or any of their respective properties or assets, or (y) violate, conflict with, result in the loss of any benefit under, constitute a default (or an event which, with notice or lapse of time, or both, would constitute a default) under, result in the termination of or a right of termination or cancellation

Except for filings required under the Exchange Act, no filings, declarations or registrations with, any Governmental Authority are necessary for the execution and delivery of this Agreement by Parent, other than such other consents, approvals, filings, declarations or registrations that, if not obtained, made or given, would not, individually or in the aggregate, reasonably be expected to have a Parent Material Adverse Effect.

      4. Termination. This Agreement shall terminate on the first to occur of (a) the termination of the Merger Agreement in accordance with its terms and (b) the Effective Time. Notwithstanding the foregoing, (i) nothing herein shall relieve any party from liability for breach of this Agreement and (ii) the provisions of this Section 4, Section 6 and paragraphs (c) and (d) of Section 2 hereof shall survive any termination of this Agreement.

      5. Escrow Agreement. Parent hereby agrees that, immediately following the Effective Time and solely for purposes of the Escrow Agreement dated as of February 13, 2004 (the “Escrow Agreement”) among the Company, the other entities and persons listed on Annex A thereto and the Escrow Agent thereunder, Parent shall cause the Company to approve an amendment to the Escrow Agreement so that the “Cut-Off Time” referred to in Section 2(a)(x) of the Escrow Agreement shall be the Effective Time. Nothing in this Section 6 shall affect in any way the rights to indemnification of the Buyer Indemnified Parties under the Purchase Agreement (each as defined in the Escrow Agreement).

      6. Miscellaneous.

      (a) Action in Stockholder Capacity Only. The parties acknowledge that this Agreement is entered into by each Stockholder in its capacity as an owner of Stockholder Shares and that nothing in this Agreement shall in any way restrict or limit any trustee or other representative of a Stockholder that also is a director or officer of the Company from taking any action in his capacity as a director or officer of the Company that is necessary for him to comply with his fiduciary duties as a director or officer of the Company, including, without limitation, participating in his capacity as a director of the Company in any discussions, negotiations or votes in accordance with Section 5.3 of the Merger Agreement.

      (b) Expenses. Except as otherwise expressly provided in this Agreement, all costs and expenses incurred in connection with the transactions contemplated by this Agreement shall be paid by the party incurring such costs and expenses.

      (c) Additional Shares. Until any termination of this Agreement in accordance with its terms, each Stockholder shall promptly notify Parent of the number of shares of Company Common Stock, if any, as to which such Stockholder acquires record or beneficial ownership after the date hereof. Any shares of Company Common Stock as to which each Stockholder acquires record or beneficial ownership after the date hereof and prior to termination of this Agreement shall be Stockholder Shares for purposes of this Agreement. Without limiting the foregoing, in the event of any stock split, stock dividend or other change in the capital structure of the Company affecting the Company Common Stock, the number of shares of Company Common Stock constituting Stockholder Shares shall be adjusted appropriately and this Agreement and the obligations hereunder shall attach to any additional shares of Company Common Stock or other voting securities of the Company issued to a Stockholder in connection therewith.

      (d) Definition of “Beneficial Ownership”. For purposes of this Agreement, “beneficial ownership” with respect to (or to “own beneficially”) any securities shall mean having “beneficial ownership” of such securities (as determined pursuant to Rule 13d-3 under the Exchange Act), including pursuant to any agreement, arrangement or understanding, whether or not in writing.

This Agreement is not intended to and shall not confer upon any Person other than the parties hereto any rights hereunder.

      (f) Assignment; Binding Effect. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto (whether by operation of law or otherwise) without the prior written consent of the other parties.

Notwithstanding the foregoing, no failure or delay by Parent in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right hereunder. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party.

      (h) Severability.

If the corporation concludes that appraisal rights are or may be available, a copy of this chapter shall accompany the meeting notice sent to those record shareholders entitled to exercise appraisal rights.

      (b) In a merger pursuant to section 11.05, the parent corporation shall notify in writing all record shareholders of the subsidiary who are entitled to assert appraisal rights that the corporate action became effective. Such notice shall be sent within 10 days after the corporate action became effective and include the materials described in section 13.22.

      SECTION 13.21.     Notice of Intent to Demand Payment. — (a) If proposed corporate action requiring appraisal rights under section 13.02 is submitted to vote at a shareholders’ meeting, a shareholder who wishes to assert appraisal rights with respect to any class or series of shares:

	(1) shall deliver to the corporation before the vote is taken written notice of the shareholder’s intent to demand payment if the proposed action is effectuated; and
	(2) shall not vote, or cause or permit to be voted, any shares of such class or series in favor of the proposed action.

      (b) A shareholder who does not satisfy the requirements of subsection (a) is not entitled to payment under this chapter.

      SECTION 13.22.     Appraisal Notice and Form. — (a) If proposed corporate action requiring appraisal rights under subsection (a) of section 13.02 becomes effective, the corporation shall deliver a written appraisal notice and form required by clause (1) of subsection (b) to all shareholders who satisfied the requirements of section 13.21 or, if the action was taken by written consent, did not consent.

	(2) state:

	(i) where the form shall be sent and where certificates for certificated shares shall be deposited and the date by which those certificates shall be deposited, which date may not be earlier than the date for receiving the required form under subclause (ii);
	(ii) a date by which the corporation shall receive the form which date may not be fewer than 40 nor more than 60 days after the date the subsection (a) appraisal notice and form are sent, and state that the shareholder shall have waived the right to demand appraisal with respect to the shares unless the form is received by the corporation by such specified date;
	(iii) the corporation’s estimate of the fair value of the shares;
	(iv) that, if requested in writing, the corporation will provide, to the shareholder so requesting, within 10 days after the date specified in clause (ii) the number of shareholders who return the forms by the specified date and the total number of shares owned by them; and

      SECTION 13.23.     Perfection of Rights; Right to Withdraw. — (a) A shareholder who receives notice pursuant to section 13.22 and who wishes to exercise appraisal rights shall certify on the form sent by the corporation whether the beneficial owner of the shares acquired beneficial ownership of the shares before the date required to be set forth in the notice pursuant to clause (1) of subsection (b) of section 13.22. If a shareholder fails to make this certification, the corporation may elect to treat the shareholder’s shares as after-acquired shares under section 13.25. In addition, a shareholder who wishes to exercise appraisal rights shall execute and return the form and, in the case of certificated shares, deposit the shareholder’s certificates in accordance with the terms of the notice by the date referred to in the notice pursuant to subclause (ii) of clause (2) of subsection (b) of section 13.22. Once a shareholder deposits that shareholder’s certificates or, in the case of uncertificated shares, returns the executed forms, that shareholder loses all rights as a shareholder, unless the shareholder withdraws pursuant to said subsection (b).

      (b) A shareholder who has complied with subsection (a) may nevertheless decline to exercise appraisal rights and withdraw from the appraisal process by so notifying the corporation in writing by the date set forth in the appraisal notice pursuant to subclause (v) of clause (2) of subsection (b) of section 13.22. A shareholder who fails to so withdraw from the appraisal process may not thereafter withdraw without the corporation’s written consent.

      (c) A shareholder who does not execute and return the form and, in the case of certificated shares, deposit that shareholder’s share certificates where required, each by the date set forth in the notice described in subsection (b) of section 13.22, shall not be entitled to payment under this chapter.

      SECTION 13.24.     Payment. — (a) Except as provided in section 13.25, within 30 days after the form required by subclause (ii) of clause (2) of subsection (b) of section 13.22 is due, the corporation shall pay in cash to those shareholders who complied with subsection (a) of section 13.23 the amount the corporation estimates to be the fair value of their shares, plus interest.

      (b) The payment to each shareholder pursuant to subsection (a) shall be accompanied by:

	(1) financial statements of the corporation that issued the shares to be appraised, consisting of a balance sheet as of the end of a fiscal year ending not more than 16 months before the date of payment, an income statement for that year, a statement of changes in shareholders’ equity for that year, and the latest available interim financial statements, if any;

	(3) a statement that shareholders described in subsection (a) have the right to demand further payment under section 13.26 and that if any such shareholder does not do so within the time period specified therein, such shareholder shall be deemed to have accepted the payment in full satisfaction of the corporation’s obligations under this chapter.

      SECTION 13.25.     After-Acquired Shares. — (a) A corporation may elect to withhold payment required by section 13.24 from any shareholder who did not certify that beneficial ownership of all of the shareholder’s shares for which appraisal rights are asserted was acquired before the date set forth in the appraisal notice sent pursuant to clause (1) of subsection (b) of section 13.22.

      (b) If the corporation elected to withhold payment under subsection (a), it must, within 30 days after the form required by subclause (ii) of clause (2) of subsection (b) of section 13.22 is due, notify all shareholders who are described in subsection (a):

	(1) of the information required by clause (1) of subsection (b) of section 13.24;
	(2) of the corporation’s estimate of fair value pursuant to clause (2) of subsection (b) of said section 13.24;
	(3) that they may accept the corporation’s estimate of fair value, plus interest, in full satisfaction of their demands or demand appraisal under section 13.26;
	(4) that those shareholders who wish to accept the offer shall so notify the corporation of their acceptance of the corporation’s offer within 30 days after receiving the offer; and
	(5) that those shareholders who do not satisfy the requirements for demanding appraisal under section 13.26 shall be deemed to have accepted the corporation’s offer.

      (c) Within 10 days after receiving the shareholder’s acceptance pursuant to subsection(b), the corporation shall pay in cash the amount it offered under clause (2) of subsection (b) to each shareholder who agreed to accept the corporation’s offer in full satisfaction of the shareholder’s demand.

      (d) Within 40 days after sending the notice described in subsection (b), the corporation must pay in cash the amount if offered to pay under clause (2) of subsection (b) to each shareholder deserved in clause (5) of subsection (b).

      SECTION 13.26.     Procedure if Shareholder Dissatisfied with Payment or Offer. — (a) A shareholder paid pursuant to section 13.24 who is dissatisfied with the amount of the payment shall notify the corporation in writing of that shareholder’s estimate of the fair value of the shares and demand payment of that estimate plus interest, less any payment under section 13.24. A shareholder offered payment under section 13.25 who is dissatisfied with that offer shall reject the offer and demand payment of the shareholder’s stated estimate of the fair value of the shares plus interest.

      (b) A shareholder who fails to notify the corporation in writing of that shareholder’s demand to be paid the shareholder’s stated estimate of the fair value plus interest under subsection (a) within 30 days after receiving the corporation’s payment or offer of payment under section 13.24 or section 13.25, respectively, waives the right to demand payment under this section and shall be entitled only to the payment made or offered pursuant to those respective sections.

JUDICIAL APPRAISAL OF SHARES

      SECTION 13.30.     Court Action. — (a) If a shareholder makes demand for payment under section 13.26 which remains unsettled, the corporation shall commence an equitable proceeding within 60 days after receiving the payment demand and petition the court to determine the fair value of the

      (b) The corporation shall commence the proceeding in the appropriate court of the county where the corporation’s principal office, or, if none, its registered office, in the commonwealth is located. If the corporation is a foreign corporation without a registered office in the commonwealth, it shall commence the proceeding in the county in the commonwealth where the principal office or registered office of the domestic corporation merged with the foreign corporation was located at the time of the transaction.

      (c) The corporation shall make all shareholders, whether or not residents of the commonwealth, whose demands remain unsettled parties to the proceeding as an action against their shares, and all parties shall be served with a copy of the petition. Nonresidents may be served by registered or certified mail or by publication as provided by law or otherwise as ordered by the court.

      (d) The jurisdiction of the court in which the proceeding is commenced under subsection (b) is plenary and exclusive. The court may appoint 1 or more persons as appraisers to receive evidence and recommend a decision on the question of fair value. The appraisers shall have the powers described in the order appointing them, or in any amendment to it. The shareholders demanding appraisal rights are entitled to the same discovery rights as parties in other civil proceedings.

      (e) Each shareholder made a party to the proceeding is entitled to judgment (i) for the amount, if any, by which the court finds the fair value of the shareholder’s shares, plus interest, exceeds the amount paid by the corporation to the shareholder for such shares or (ii) for the fair value, plus interest, of the shareholder’s shares for which the corporation elected to withhold payment under section 13.25.

      SECTION 13.31.     Court Costs and Counsel Fees. — (a) The court in an appraisal proceeding commenced under section 13.30 shall determine all costs of the proceeding, including the reasonable compensation and expenses of appraisers appointed by the court. The court shall assess the costs against the corporation, except that the court may assess cost against all or some of the shareholders demanding appraisal, in amounts the court finds equitable, to the extent the court finds such shareholders acted arbitrarily, vexatiously, or not in good faith with respect to the rights provided by this chapter.

      (b) The court in an appraisal proceeding may also assess the fees and expenses of counsel and experts for the respective parties, in amounts the court finds equitable:

	(1) against the corporation and in favor of any or all shareholders demanding appraisal if the court finds the corporation did not substantially comply with the requirements of sections 13.20, 13.22, 13.24 or 13.25; or
	(2) against either the corporation or a shareholder demanding appraisal, in favor of any other party, if the court finds that the party against whom the fees and expenses are assessed acted arbitrarily, vexatiously, or not in good faith with respect to the rights provided by this chapter.

      (c) If the court in an appraisal proceeding finds that the services of counsel for any shareholder were of substantial benefit to other shareholders similarly situated, and that the fees for those services should not be assessed against the corporation, the court may award to such counsel reasonable fees to be paid out of the amounts awarded the shareholders who were benefited.

      (d) To the extent the corporation fails to make a required payment pursuant to sections 13.24, 13.25, or 13.26, the shareholder may sue directly for the amount owed and, to the extent successful, shall be entitled to recover from the corporation all costs and expenses of the suit, including counsel fees.
