Retirement Plu$ Plan Lincoln, Nebraska We have audited the accompanying statements of net assets available for benefits of the Isco, Inc. Retirement Plu$ Plan as of July 31, 1996 and 1995 and the related statements of changes in net assets available for benefits for the years then ended. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on the 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 also 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, such financial statements present fairly, in all material respects, the net assets available for benefits of the Isco, Inc. Retirement Plu$ Plan as of July 31, 1996 and 1995, and the changes in net assets available for benefits for the years then ended, in conformity with generally accepted accounting principles. Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules of (1) assets held for investment purposes as of July 31, 1996, and (2) reportable transactions for the year ended July 31, 1996, are presented for the purpose of additional analysis and are not a required part of the basic financial statements, but are supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental information by fund in the statements of net assets available for benefits and the statements of changes in net assets available for benefits is presented for the purpose of additional analysis rather than to present the net assets available for benefits and changes in net assets available for benefits of the individual funds. The supplemental schedules and supplemental information by fund is the responsibility of the Plan's management. Such supplemental schedules and supplemental information by fund have been subjected to the auditing procedures applied in our audit of the basic 1996 financial statements and, in our opinion, are fairly stated in all material respects when considered in relation to the basic financial statements taken as a whole.

RETIREMENT PLU$ PLAN NOTES TO FINANCIAL STATEMENTS Years ended July 31, 1996 and 1995 (Columnar amounts in thousands, except share data) A. DESCRIPTION OF PLAN General - The following brief description of the Isco, Inc. Retirement Plu$ Plan (the Plan) is provided for general information purposes only. Participants should refer to the Plan document for more complete information. The Plan was established effective August 1, 1972 to provide retirement benefits for the employees of Isco, Inc. (the Company). The Plan was last amended effective August 1, 1995. Effective August 1, 1987, a 401(k) salary reduction option was incorporated into the Plan. Employees are eligible for participation after they have completed one year of service and are at least 21 years of age. A year of service is defined as the accumulation of 1,000 hours of credited service during a one-year period beginning on the employment date. Participant contributions, employer 401(k) matching contributions, and employer annual profit sharing contributions, are invested at Twentieth Century Investors under the direction of the plan participants. Funding - Contributions to the Plan are provided from the following sources: Employer Annual Profit Sharing Contribution (Participant Directed) - The Employer is required to contribute an amount equal to the lesser of 7% of the current net profit of the Company or the maximum amount allowed by the Internal Revenue Code. The contributed amount received by each participant is based on their percentage of total eligible compensation. Participant Contributions (Participant Directed) - Plan participants may elect to reduce their compensation by a maximum of 12%, subject to IRS limitations. The Employer then contributes the amount of reduction in compensation to the Plan on behalf of each participant. Employer 401(k) Matching Contribution (Participant Directed) - The Employer is required to match 20% of the contribution made on behalf of each participant electing salary reductions up to a maximum of 10% of the participant's eligible compensation. Participant Accounts - Each participant's account is credited with the participant's contribution, the Company's matching contribution and the allocated portion of: the Company's annual contribution, and the forfeited portion of terminated participants' non-vested accounts. Any 401(k) forfeitures are allocated, based on a participant's contributions to the 401(k) plan during the year. The Company's annual contribution and forfeitures are allocated to each participant's account based on the percentage of the participant's eligible compensation for the plan year to the total compensation of all eligible participants for the plan year. Earnings are credited directly to each investment option in which the participant had an investment on the record date of the dividend or interest distribution. 44 Vesting - Participant contributions (i.e. employee salary reduction amounts) and participant rollover contributions are immediately fully vested and nonforfeitable. Employer profit sharing contributions and the Employer 401(k) matching contributions vest 20% upon completion of three years of credited service, increasing 20% per year until fully vested upon completion of seven years of credited service. Plan participants are eligible for normal retirement at age 65 but may elect to retire at a later date. Upon attainment of 65 years of age, death, or determination of disability, a participant becomes 100% vested regardless of the number of credited years of service completed. Plan Expenses - As an additional benefit to the participants, the Employer, without reimbursement, pays for all costs required to administer the Plan. These costs are not reflected in the financial statements. B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Valuation of Investments - Investments are stated at fair value. Fair value of marketable securities is determined by reference to the closing quoted price by the exchange on which the security is listed or the closing net asset value as reported by the mutual fund. Participant loans are stated at their outstanding principal balance. The amounts shown in Note C for securities that do not have a quoted market price represent fair value estimated by an independent third party. Investment transactions are recognized on a settlement date basis. The net realized and unrealized appreciation (depreciation) of investments is recognized in the statements of changes in net assets available for benefits. The fair value at the beginning of the plan year, or the purchased cost if acquired during the year, is used in determining realized and unrealized gains and losses on the sale of each investment. Employer Directed - Employer directed funds are invested in the Restricted Fund, which is managed by the employer. Assets in the Restricted Fund at July 31, 1996 include: Balcor Pension Investors II and III, Bankers Trust Stable Value Government Trust, and Chase Manhattan Bank Pooled Investment. Transfers from the Restricted Fund to the Unrestricted Fund are directed by the Plan Committee. Participant Directed - Participant directed contributions may be invested in one or more of seven funds. A summary description of each investment alternative follows: Bankers Trust Stable Value Government Trust Fund - A fund which seeks to provide current income while maintaining a stable share price. It is managed by Bankers Trust Company Investment Management Group. Twentieth Century Premium Managed Bond Fund - A fund which seeks a high level of income from a portfolio of longer-term bonds and other debt obligations. The fund pays a reduced management fee. Twentieth Century Balanced Investors Fund - A fund which seeks capital growth and current income by investing in equity securities with prospects for growth and in investment grade bonds and other fixed income securities. 45 Twentieth Century Select Investors Fund - A fund comprised primarily of income-producing equity securities of larger companies possessing potential for appreciation. Twentieth Century Ultra Investors Fund - A fund comprised primarily of equity securities of medium and smaller companies with the potential for appreciation. Twentieth Century International Equity Fund - A fund which seeks capital growth by investing primarily in an internationally diversified portfolio of common stocks. Isco, Inc. Common Stock Fund - A fund invested primarily in Isco, Inc. common stock. Isco, Inc. is a related party and sponsor of the Plan. Benefits Payable - The Plan's policy is to record benefit payments upon distribution to the participants. Benefits payable to retired and terminated participants were $830,203 and $34,039 at July 31, 1996 and 1995, respectively. Contributions - Employer profit sharing contributions are computed as of the end of the Employer's fiscal year and are recorded by the Plan in the corresponding period, but allocated to participants' accounts in the plan quarter in which the profit sharing contribution is made to the Plan. Participant contributions are recorded in the period in which the bi- weekly payroll deductions are made. The Employer 401(k) matching contributions are also recorded in the period that the payroll deductions are made. 46 C. INVESTMENTS The following schedule presents the fair values of investments.

PLAN TERMINATION Although the Company has not expressed any intent to terminate the Plan, it may do so at any time by giving 30 days notice to the Plan Committee, the Plan Administrator, and the Trustee. In the event of such termination, Plan assets would be valued and participants' accounts would be adjusted to reflect the allocation of net gains and losses of the underlying investments. At that time, participants' accounts would become fully vested and nonforfeitable. E. FEDERAL INCOME TAX STATUS The Plan has received a determination letter from the Internal Revenue Service dated September 7, 1995, which states that the Plan, as amended June 17, 1994, meets the requirements of Section 401(a) of the Internal Revenue Code and is, therefore, exempt from Federal income tax under Section 501(a) of the Code. The Plan administrator believes that the Plan is in compliance with current regulations. Therefore, no provision for income taxes is provided in the financial statements of the Plan. Plan income, participant pretax contributions, and employer contributions represent taxable income to the participating employees at the time of distribution. 48 F.
