Pursuant to Item 4 of Form 11-K, the financial statements and schedules referred to above have been prepared in accordance with regulations of the Employee Retirement Income Security Act of 1974. 3 INDEPENDENT AUDITORS' REPORT MINNEGASCO DIVISION EMPLOYEES' RETIREMENT SAVINGS PLAN: We have audited, by fund and in total, the accompanying financial statements of the Minnegasco Division Employee Retirement Savings Plan ("Plan") as of December 31, 1997 and for the year then ended, listed in the Table of Contents. 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 audit. We conducted our audit 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 audit provide a reasonable basis for our opinion. In our opinion, such financial statements present fairly, by fund and in total, in all material respects, the net assets available for benefits of the Plan as of December 31, 1997, and the changes in net assets available for benefits for the year then ended in conformity with generally accepted accounting principles. Our audit was conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The accompanying supplemental schedules, listed in the Table of Contents, 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. These schedules are the responsibility of Plan's management. Such have been subjected to the auditing procedures applied in our audit of the basic 1997 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. DELOITTE & TOUCHE LLP Houston, Texas June 24, 1998 1 4 REPORT OF INDEPENDENT ACCOUNTANTS MINNEGASCO DIVISION EMPLOYEES' RETIREMENT SAVINGS PLAN: We have audited the accompanying statement of net assets available for benefits of the Minnegasco Division Employees' Retirement Savings Plan as of December 31, 1996, and the related statement of changes in net assets available for benefits for the year then ended. 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 audit. We conducted our audit 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 audit provides 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 benefits of the Minnegasco Division Employees' Retirement Savings Plan as of December 31, 1996, and the changes in net assets available for benefits for the year then ended, in conformity with generally accepted accounting principles. Our audit was performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The fund information in the statement of net assets available for benefits as of December 31,1996 and the statement of changes in net assets available for benefits for the year then ended 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 each fund. The fund information has been subjected to the auditing procedures applied in the audit of the basic 1996 financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

See notes to financial statements. 6 9 MINNEGASCO DIVISION EMPLOYEES' RETIREMENT SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS FOR THE YEARS ENDED DECEMBER 31, 1997 AND 1996 1. ACCOUNTING POLICIES In accordance with the provisions of the Minnegasco Division Employees' Retirement Savings Plan ("Plan"), of the Minnegasco Division (the "Company" or "Minnegasco") of NorAm Energy Corp. ("NorAm") (see Note 5), the financial records of the Plan are generally kept and the valuations of accounts of participating employees ("Participants") are determined on the accrual basis. Interest income is recorded as earned on the accrual basis. The Plan recognizes net appreciation or depreciation in the fair value of its investments. Investments are reflected at fair value in the financial statements. Fair value for securities listed on a national exchange is principally determined using the closing price on the New York Stock Exchange. Fair value for mutual funds is determined using net asset value. Investments in common stock are stated at quoted market prices of the stock on the last day of business of the year. Purchases and sales of investments are recorded on their trade date. The preparation of financial statements in conformity with generally accepted accounting principles requires estimates and assumptions that affect the reported amounts as well as certain disclosures. The Plan's financial statements include amounts that are based on management's best estimates and judgments. Actual results could differ from those estimates. Benefit payments are recorded when paid. 2. SUMMARY OF THE PLAN GENERAL The Plan is a defined contribution plan formed by the combination of two previously separate benefit programs. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"). The Plan is an eligible individual account plan as defined by ERISA Section 407((d)(3)) which is authorized to acquire and hold qualifying employee securities (as defined by ERISA Section 407((d)(3)) with a value in excess of ten percent of the fair market value of the assets of the Plan. The Retirement Savings Plan program was added to the Plan in 1983 to provide employees a pre-tax savings option. As of January 1, 1990, the Stock Purchase Plan is no longer available to employees as the collective bargaining groups who previously participated in the Stock Purchase Plan have elected to participate in the Retirement Savings Plan. Contributions are no longer made to the Stock Purchase Plan. The Benefits Committee ("Committee") appointed by the Board of Directors of Houston Industries Incorporated ("HII"), is responsible for directing American Express Bank & Trust ("Trustee"), in the day to day administration of the Plan. All administrative expenses not paid by Minnegasco are borne by the Plan. 7 10 INVESTMENT PROGRAMS Retirement Savings Plan participants direct the investment of contributions allocated to their accounts to one or more of the following investment funds held by the Trustee: HII COMMON STOCK FUND: Invested primarily in shares of common stock of HII (formerly NorAm Energy Corp. Pooled Common Stock Fund). See note 5 regarding the merger of HII and NorAm. IDS U.S. GOVERNMENT SECURITIES FUND: Invests in short-term bond or debt instruments guaranteed as to principal and interest by the U.S. Government or its agencies or instrumentalities. IDS SELECTIVE FUND INC.: Invests in a portfolio of primarily high-quality corporate bonds, government securities and money market securities. IDS MUTUAL FUND: Invests in a portfolio of common stocks, which offer capital appreciation, and in senior securities, such as bonds and preferred stocks, that offer fixed interest and dividend payments. IDS DIVERSIFIED EQUITY INCOME FUND: Invests in a portfolio of medium to large, well-established companies that offer long-term capital growth potential as well as reasonable income from dividends and interest. IDS EQUITY INDEX FUND I: Invests primarily in medium-to-large, well-established companies offering both long-term capital appreciation and income potential. IDS NEW DIMENSIONS FUND: Invests in a portfolio of primarily common stocks of U.S. and foreign companies in which powerful economic and technical changes may take place.

8 11 PARTICIPANT ACCOUNTS Each Participant's account is credited with the Participant's and Minnegasco's contributions, and an allocation of the Plan's earnings. Earnings allocations are based on Participant account balances as defined by the Plan. The allocation of the Participant's contributions to the investment funds is selected by the Participant and may be changed at any time. Allocation between funds is at the discretion of the Participant. Contributions for each calendar month shall be deemed to have been deposited as of the last day of such month for purposes of allocating investment earnings. PARTICIPATION Eligible employees may contribute up to 12% of their earnings to the Retirement Savings Plan as pre-tax savings contributions. Company's matching contributions are equal to 50% of the first 6% of employee pre-tax contributions. Participants of the Retirement Savings Plan can also designate that their portion of the Company contribution to the DEI Flexible Benefits Plan be contributed to the Retirement Savings Plan. The Company does not match these additional contributions. However, by Resolution of the Board of Directors of HII, HII has the discretion to determine the matching contribution from year to year and may specify a zero percentage. The Retirement Savings Plan is available to all full-time employees with at least 30 days of service, part-time employees scheduled to work more than 1,000 hours per year with at least 30 days of experience, and other part time employees with one year of service. The Plan is not available to employees covered by a collective bargaining agreement unless the bargaining agreement expressly provides that such employee will be eligible to participate. In addition the Plan is not available to non-resident aliens, interns, temporary employees, seasonal employees, and leased employees. DISTRIBUTIONS AND FORFEITURES A terminated Participant or the beneficiary of a deceased Participant is entitled to a distribution of the value of the Participant's entire account in case of death, disability, or retirement at or after the later of (i) the Participant's attainment of age 65 or (ii) the fifth anniversary of the Participant's commencement of participation in the Plan. In case of termination of service for other reasons, a Participant is entitled to a distribution of the entire value of his contribution account plus the vested portion of his Employer Contribution account. Vesting is determined by vesting service years in accordance with the following schedule:
Vesting Service Vested Years Percentage --------------- ---------- Less than three ............................ 0% Three but less than four ................... 50% Four but less than five .................... 75% Five or more ............................... 100%
Any portion of the value of the Company's contributions not vested will be forfeited. The amount forfeited by a Participant is applied to reduce the respective Company's subsequent contribution to the Plan. A terminated Participant may elect a lump sum distribution or installment payments of the vested amount accumulated in each participant's account. Immediate lump sum distributions are made for accounts which do not exceed $3,500. 9 12 PARTICIPANT LOANS A Participant may borrow up to 50% of their vested account balance, up to a maximum of $50,000, reduced by the excess, if any, of the highest outstanding loan balance during the previous 12 months of loans issued to the Participant from all plans maintained by Minnegasco or an affiliated entity during the one-year period ending on the day before the date on which such loan is made over the outstanding balance of loan from the Plan on the date on which such loan is made ($1,000 minimum). A Participant may have only one loan outstanding at any one time. Interest rates are fixed for the term of the loan at the time of loan origination and ranged from 9.25% to 9.5% on loans originated during 1997 and ranged from 8.25% to 10% for loans outstanding as of December 31, 1997. Principal and interest payments are paid ratably through monthly payroll deductions over a term not to exceed sixty months. Participants' account balances are used as collateral for the loans. TERMINATION OF THE PLAN Although it has not expressed any intent to do so, HII has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, Participants will become 100% vested in their accounts and the Plan assets will be distributed by the trustee only after the occurrence of death, disability, retirement or other termination of employment or pursuant to the Plan's withdrawal provisions. 3. FEDERAL INCOME TAXES No provision for federal income taxes has been made in the financial statements of the Plan. The Internal Revenue Service determined and informed Minnegasco, by letter dated October 10, 1995 that the Plan, as amended, qualifies under Section 401(a) and 401(k) of the Internal Revenue Code ("Code") and is exempt from federal taxes under the provisions of Section 501 (a). Although the Plan was amended, the Committee and the Minnegasco's counsel believe that the Plan was designed and operated in compliance with the requirements of the Code. As a result, the Participant's Pre-tax Contributions, up to a specified maximum amount each calendar year, and the Employer Contributions to the Trust on behalf of a Participant are not currently taxable to a Participant when made, and income from any source accruing to a Participant's account is not taxable when realized by the Trust. The After-tax Contributions made by a Participant will not be deductible by the Participant. However, Participant withdrawals of After-tax Contributions made to the Plan prior to May 3, 1994, are excludable from the Participant's gross income for federal income tax purposes. The continued status of the Trust as a tax-exempt trust and the Plan as a qualified plan are contingent upon the continuing operation of the Trust and the Plan in accordance with applicable provisions of the Code. 4. RELATED PARTY TRANSACTIONS The Trustee is authorized under contract provisions and by ERISA regulations providing administrative and statutory exemptions, to invest in funds under its control and in securities of HII. During 1997 and 1996, the Trustee purchased and sold units of HII and NorAm Common Stock and IDS Trust Funds as temporary investments, which are shown below (in thousands):
1997 1996 ------------ ------------ Purchases (HII) $ 3,524,761 Purchases (NorAm) $ 2,444,166 (Trustee) 33,691,803 (Trustee) 14,825,298 Sales (HII) $ 32,300,714 Sales (NorAm) $ 4,844,911 (Trustee) 17,711,722 (Trustee) 11,255,745
10 13 5. MERGER WITH HOUSTON INDUSTRIES INCORPORATED On August 6, 1997, Minnegasco's parent NorAm merged with and into a subsidiary of HII and became a wholly owned subsidiary of HII. Consideration for the purchase of NorAm's Common Stock was a combination of cash and HII Common Stock. As a result of the merger, the Plan Participants received cash and HII Common Stock as merger consideration in exchange for their NorAm common stock. The cash portion of merger consideration received was automatically invested based upon Participant investment elections. The Merger Agreement stipulates that HII, for a period of one year subsequent to the consummation of the Merger will continue or cause to be continued, without adverse change to any employee or former employee, all NorAm benefit plans. 11 14 Item 27a-Schedule of Assets Held for Investment Purposes MINNEGASCO DIVISION EMPLOYEES' RETIREMENT SAVINGS PLAN SUPPLEMENTAL SCHEDULE OF INVESTMENTS ASSETS HELD FOR INVESTMENT PURPOSES DECEMBER 31, 1997
