These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit 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 financial condition of the Ionics Section 401(k) Stock Savings Plan at December 31, 1993 and 1992 and the income and changes in plan equity for each of the three years in the period ended December 31, 1993, in conformity with generally accepted accounting principles.

Matching Company contributions under the Plan are invested solely in common stock of the Company. A brief description of each investment fund follows: a. Ionics, Incorporated Common Stock Fund - This fund invests directed contributions solely in common stock of the Company. There were 438 active participants in this fund at December 31, 1993. b. Fidelity Equity Income Fund - This mutual fund maintains a broadly-based diversified investment portfolio of stocks, bonds and convertible securities with its primary objective of producing current income and capital appreciation. There were 168 active participants in this fund at December 31, 1993. c. Fidelity Cash Reserves - This mutual fund is essentially a money market fund which invests principally in prime commercial paper, high-grade corporate obligations, U.S. Government obligations and Certificates of Deposit issued by major banks. There were 82 active participants in this fund at December 31, 1993. d. 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. There were 147 active participants in this fund at December 31, 1993. Note 2: Investments Investment of the Plan in Ionics, Incorporated common stock is stated at market, market being the last sale price on December 31, 1993 of Ionics, Incorporated common stock as reported on the New York Stock Exchange.

Note 3: Taxes The United States Treasury Department issued a letter on April 15, 1987 indicating that the Plan met the requirements of Section 401(a) and Section 401(k), and accordingly the Plan is considered to be exempt from federal income taxes under provisions of Section 501(a). Elective contributions made to a plan under a qualified cash-or- deferred arrangement are not includible in the employee's gross income. Income taxes are postponed until the employee receives a distribution from the plan. In addition, earnings on elective contributions are accumulated tax-free until distributed. -9- Note 4: Subsequent Events Effective May 1, 1994, the Plan was amended to comply with regulation 404(c) by providing multiple investment selections for plan participants and the opportunity to change investment elections on a quarterly basis. The cash reserve and equity-income investment options were eliminated and replaced by a guaranteed investment contract (GIC), asset allocation and growth fund options. Also, the Plan was amended to include loan provisions for the participants based on certain rules including a minimum amount of $1,000 and a maximum not to exceed the lesser of 50% of the participant's total vested account balance or $50,000. -10- SIGNATURES Ionics Section 401(k) Stock Savings Plan.
