These financial statements and the schedules referred to below are the responsibility of the plan administrator. Our responsibility is to express an opinion on these financial statements and schedules based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for plan benefits of the Plan as of December 31, 1998 and 1997 and the changes in its net assets available for plan benefits for the years then ended, in conformity with generally accepted accounting principles. Our audits were made for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules of assets held for investment purposes, reportable transactions and nonexempt transactions are presented for purposes of complying with the Department of Labor Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974 and are not a required part of the basic financial statements. Such schedules have been subjected to the auditing procedures applied in the audit of the basic financial statements and, in our opinion, are fairly stated, in all material respects, in relation to the basic financial statements taken as a whole. /s/BELANGER & COMPANY, P.C.

Effective May 1, 1994, the Plan was amended to provide a broader range of investment selections for Plan participants and the opportunity to change investment elections on a quarterly basis. Other amendments to the Plan were also adopted, including provisions to permit participants to borrow from their accounts. On August 25, 1997, the Plan was amended to increase the number of investment options, reduce the period for changing contribution rates from quarterly to monthly, and institute daily account valuation. In addition, the trustee was changed from PNC Bank to New York Life Trust Company. Participants should refer to the Summary Plan Description for a more complete description of the Plan's provisions. General The Plan is a defined contribution plan qualified under Section 401(k) of the U.S. Internal Revenue Code covering all permanent employees of Ionics, Incorporated and domestic subsidiaries (the "Company") working at least 20 hours per week who have completed one year of service. The Plan was established to provide benefits to participants upon retirement, termination of employment, death, permanent and total disability, or demonstration of financial hardship. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974. Investment Options The following investment options are available to participants: Ionics, Incorporated Common Stock Fund - This fund invests directed contributions solely in common stock of the Company. Fidelity Puritan Fund - This mutual fund maintains a broadly based conservatively managed diversified investment portfolio which is primarily income oriented with a secondary emphasis on growth. Its portfolio consists principally of high yielding common and preferred stocks and corporate bonds. Fidelity Contrafund - This mutual fund invests primarily in common stocks and securities convertible into common stocks, and has capital appreciation as its investment objective. -7- /19 MainStay Institutional Indexed Bond Fund - This income mutual fund invests in investment grade corporate and U.S. Government bonds, mortgage- backed securities and asset-backed securities. The fund measures itself by the Salomon Brothers Broad Investment Grade Bond Index. MainStay Institutional Multi-Asset Fund - This fund is an asset allocation mutual fund which varies the amount invested in each class of assets, based on anticipated risks and returns associated with each class. The fund invests in domestic and foreign common stocks, fixed income securities and money market instruments. Its objective is to maximize total return. MainStay Institutional Indexed Equity Fund - This fund is a growth and income mutual fund. The fund seeks to correspond with the Standard & Poor's Composite Index of 500 Stocks. Janus Worldwide Fund - This fund seeks long-term growth with preservation of capital. It invests mainly in common stocks of domestic and foreign issuers. It will normally invest in issuers from at least five different countries, including the United States. Foreign investing may be subject to greater risks than domestic investing. BT Pyramid GIC Fund - This fund, administered by The Bankers Trust Company, invests primarily in Guaranteed Investment Contracts and Bank Investment Contracts and Bankers Trust Commingled short-term investment funds, and has as its objectives safety of principal, stability, superior yields and a predictable annual return. The fund sets an estimated range of return on an annual basis, but because results can be affected by economic or market conditions, it does not guarantee the rate. All cash transactions, including contributions, fund purchases, fund liquidations, loans, distributions, etc. were made through a conduit account, which is an interest bearing cash account with the PNC Bank, New England. On August 25, 1997 this account was changed to the MainStay Institutional Money Market Fund. Participant Contributions Employees who meet certain length of service requirements may elect to become participants in the Plan and contribute, on a pre-tax basis, from 1% to 12% of their compensation as defined by the Plan. The annual amounts so contributed by employees are subject to certain federal income tax limitations. Contributions made by employees to the Plan may be used to purchase either common stock of the Company or may be directed to be invested in any of the available investment funds. Participant Accounts Each participant's account is credited with the participant's contribution and an allocation of Plan earnings. Allocations are based on total investment earnings and average participant investment balances, as defined. -8- /20 Company Contribution The terms and conditions of the Plan provide for the Company to contribute 50% of the first 6% an employee elects to invest in common stock of the Company (subject to certain limitations). The maximum annual amount that the Company may contribute on behalf of employees is currently $900,000, and that limit is set by the Board of Directors of the Company. Matching Company contributions under the Plan are invested solely in common stock of the Company. Non-vested Company contributions may, subject to certain restrictions, be forfeited upon withdrawal of the employee from the Plan and be used as a credit to reduce future Company contributions. Vesting All participant contributions are 100% vested when made. Company matching contributions are vested in increasing percentages based on the years of service of the individual employee, from 33 1/3% after two years to 100% after four years. Plan Expenses The Plan provides that all expenses of the Plan and its administration shall be paid by the Company. Withdrawals A participant can make a hardship withdrawal of his or her own contributions, subject to Internal Revenue Service restrictions. A participant may withdraw the entire vested amount due to his or her own contributions after attaining age 59 1/2. Loans A participant can borrow money from his or her vested account subject to certain rules including a minimum amount of $1,000 and a maximum amount not to exceed the lesser of 50% of the participant's total vested account balance or $50,000.
