Its Houston Lighting & Power Company division is an electric utility serving approximately 1.6 million customers in the City of Houston, Texas, and surrounding areas on the Texas Gulf Coast. NorAm, the Company's largest subsidiary, is a natural gas utility serving over 2.8 million customers in Arkansas, Louisiana, Minnesota, Mississippi, Oklahoma and Texas. NorAm, through its subsidiaries, is also a major interstate natural gas pipeline company and a provider of energy marketing services. The Company's other principal subsidiaries include Houston Industries Energy, Inc., which participates in the privatization of foreign generating and distribution facilities and the development and acquisition of foreign independent power projects, and Houston Industries Power Generation, Inc., which participates in the acquisition, development and operation of domestic non-rate regulated power generation facilities. The Company acquired NorAm in August 1997 in a transaction involving the merger (the "Company Merger") of the Company's former parent corporation, Houston Industries Incorporated ("Former HI"), into the Company, and the merger (the "NorAm Merger" and, collectively with the Company Merger, the "Mergers") of NorAm's predecessor corporation ("Former NorAm") into a newly formed subsidiary of Former HI. As a result of the Mergers, NorAm became a wholly owned subsidiary of the Company. The Company, subject to certain limited exceptions, is exempt from regulation as a public utility holding company pursuant to Section 3(a)(2) of the Public Utility Holding Company Act of 1935, as amended. The executive offices of the Company and NorAm are located at Houston Industries Plaza, 1111 Louisiana, Houston, Texas 77002 (telephone number: 713- 207-3000). USE OF PROCEEDS Because the shares of Common Stock offered hereby will be issued upon conversion of the Convertible Debentures, the Company will not receive any proceeds upon such issuance. PLAN OF DISTRIBUTION ISSUANCE OF COMMON STOCK UPON CONVERSION OF CONVERTIBLE DEBENTURES The Mergers were effected pursuant to the Agreement and Plan of Merger, dated as of August 11, 1996, as amended (the "Merger Agreement"), by and among Former HI, the Company, Former NorAm, and HI Merger, Inc., a Delaware corporation and a wholly owned subsidiary of Former HI. As a result of the Mergers, NorAm became a wholly owned subsidiary of the Company. Pursuant to the terms and conditions of the Merger Agreement, the Company agreed to be bound by the conversion provisions of the Convertible Debentures. Under the terms of the Indenture, dated as of June 15, 1996, as amended and supplemented (the "Indenture"), between NorAm, as successor in interest to Former NorAm, and The Bank of New York, as trustee, the holder of a Convertible Debenture has the right to convert such Convertible Debenture at any time on or prior to June 30, 2026 (unless such maturity date is extended by NorAm to a date not later than June 30, 2045 upon satisfaction of certain requirements and conditions) into the amount, subject to the adjustments provided for in the Indenture, of Stock Consideration (as defined below) and Cash Consideration (as defined below) which the holder thereof would have had the right to receive after the effective time of the NorAm Merger if such Convertible Debenture had been converted immediately prior to the effective time of the NorAm Merger and the holder thereof had made the election to receive Stock Consideration with respect to 50% of the shares of NorAm Common Stock (as defined below) and Cash Consideration with respect to the remaining 50% of the shares of NorAm Common Stock. At the effective time of the NorAm Merger, the Convertible Debentures were convertible into NorAm Common Stock at a conversion price of $12.125 per share. 3 "NorAm Common Stock" means the common stock, par value $.625 per share, of Former NorAm that a holder of a Convertible Debenture would have had the right to receive under the terms of the Indenture if such holder had exercised the conversion privilege of the Convertible Debentures immediately prior to the effective time of the NorAm Merger. "Cash Consideration" means the cash amount of $16.3051 per share of NorAm Common Stock. "Stock Consideration" means 0.74963 shares of Common Stock per share of NorAm Common Stock. Pursuant to the terms of the Indenture and the Merger Agreement, Common Stock may be issued to holders of Convertible Debentures from time to time upon the exercise of the conversion privilege of the Convertible Debentures by a holder thereof in accordance with the terms of the Indenture. DESCRIPTION OF COMMON STOCK The authorized capital stock of the Company consists of 700,000,000 shares of Common Stock, 10,000,000 shares of Preferred Stock, without par value, and 10,000,000 shares of Preference Stock, without par value ("Preference Stock"), of which (i) 700,000 shares have been designated by the Board of Directors of the Company as Series A Preference Stock ("Series A Preference Stock"), (ii) 27,000 shares have been designated by the Board of Directors of the Company as Series B Preference Stock ("Series B Preference Stock") and (iii) 1,575 shares have been designated by the Board of Directors of the Company as Series C Preference Stock ("Series C Preference Stock"). Each share of Common Stock offered hereby includes an associated preference stock purchase right (a "Right"). The shares of Series A Preference Stock have been initially reserved for issuance upon exercise of the Rights. The descriptions of each of the Common Stock and the Rights are incorporated by reference into this Prospectus. See "Incorporation of Certain Documents by Reference" for information on how to obtain a copy of these descriptions.

INDEMNIFICATION OF DIRECTORS AND OFFICERS. Article 2.02.A.(16) and Article 2.02-1 of the Texas Business Corporation Act and Article V of the Company's Amended and Restated Bylaws provide the Company with broad powers and authority to indemnify its directors and officers and to purchase and maintain insurance for such purposes. Pursuant to such statutory and Bylaw provisions, the Company has purchased insurance against certain costs of indemnification that may be incurred by it and by its officers and directors. Additionally, Article IX of the Company's Restated Articles of Incorporation provides that a director of the Company is not liable to the Company or its shareholders for monetary damages for any act or omission in the director's capacity as director, except that Article IX does not eliminate or limit the liability of a director for (i) breaches of such director's duty of loyalty to the Company and its shareholders, (ii) acts or omissions not in good faith or which involve intentional misconduct or knowing violations of law, (iii) transactions from which a director receives an improper benefit, irrespective of whether the benefit resulted from an action taken within the scope of the director's office, (iv) acts or omissions for which liability is specifically provided by statute and (v) acts relating to unlawful stock repurchases or payments of dividends. Article IX also provides that any subsequent amendments to Texas statutes that further limit the liability of directors will inure to the benefit of the directors, without any further action by shareholders. Any repeal or modification of Article IX shall not adversely affect any right of protection of a director of the Company existing at the time of the repeal or modification. See "Item 17. Undertakings" for a description of the Commission's position regarding such indemnification provisions. ITEM 16. EXHIBITS. See Index to Exhibits at page II-4. ITEM 17. UNDERTAKINGS. (a) The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the II-1 aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

amended (the "Securities Act"), relating to the issuance from time to time of up
to 3,000 shares (the "Shares") of common stock, without par value, of the
Company (and associated rights to purchase Series A Preference Stock, without
par value, of the Company (the "Rights")) upon conversion of the 6 1/4%
Convertible Junior Subordinated Debentures (the "Debentures") of NorAm Energy
Corp. (formerly known as HI Merger, Inc.), a Delaware corporation ("New NorAm").
The Debentures are governed by an Indenture dated as of June 15, 1996, as
amended and supplemented (the "Indenture"), between New NorAm as successor in
interest to NorAm Energy Corp., a Delaware corporation ("Old NorAm"), and The
Bank of New York, as trustee.

     In our capacity as your counsel in the connection referred to above, we
have examined the Restated Articles of Incorporation and Amended and Restated
Bylaws of the Company, each as amended to date, the Agreement and Plan of Merger
dated as of August 11, 1996, as amended, by and among Houston Industries
Incorporated, a Texas corporation ("Old HII"), the Company (formerly a wholly
owned subsidiary of Old HII), New NorAm and Old NorAm, the Indenture, and the
Amended and Restated Rights Agreement dated as of August 6, 1997 between the
Company and Chase Bank of Texas, National Association (formerly known as Texas
Commerce Bank National Association) (the "Rights Agreement") and have examined
originals, or copies certified or otherwise identified, of corporate records of
the Company, including minute books of the Company as furnished to us by the
Company, certificates of public officials and of representatives of the Company,
statutes and other instruments or documents, as a basis for the opinions
hereinafter expressed. In giving such opinions, we have relied upon certificates
of officers of the Company with respect to the accuracy of the material factual
matters contained in such certificates. In making our examination, we have
assumed that all signatures on all documents examined by us are genuine, that
all documents submitted to us as originals are accurate and complete, that all
documents submitted to us as copies are true and correct copies of the originals
thereof and that all information submitted to us was accurate and complete.

 
Houston Industries Incorporated       -2-                           July 2, 1998


     On the basis of the foregoing, and subject to the assumptions, limitations
and qualifications set forth herein, we are of the opinion that:
 
     1.   The Company is a corporation duly organized and validly existing in
  good standing under the laws of the State of Texas.

     2.   The Shares, when duly issued upon conversion of the Debentures in
  accordance with the terms thereof and the terms and provisions of the
  Indenture, will be validly issued, fully paid and non-assessable.

     3.   The issuance of the Rights associated with the Shares has been duly
  authorized by all requisite corporate action on the part of the Company and,
  upon issuance from time to time in connection with the issuance of the
  associated Shares as provided above and in accordance with the terms of the
  Rights Agreement, the Rights associated with such Shares will be validly
  issued.

     The opinion set forth in paragraph 3 above is limited to the valid issuance
of the Rights under the Texas Business Corporation Act. In this connection, we
do not express any opinion herein on any other aspect of the Rights, the effect
of any equitable principles or fiduciary considerations relating to the adoption
of the Rights Agreement or the issuance of the Rights, the enforceability of any
particular provisions of the Rights Agreement, or the provisions of the Rights
Agreement which discriminate or create unequal voting power among shareholders.

     The opinions set forth above are limited in all respects to matters of
Texas law as in effect on the date hereof. At your request, this opinion is
being furnished to you for filing as Exhibit 5 to the Registration Statement.
Additionally, we hereby consent to the reference to our Firm under the caption
"Legal Opinions" in the Registration Statement. In giving such consent, we do
not thereby concede that we are within the category of persons whose consent is
required under Section 7 of the Securities Act or the rules and regulations of
the Commission promulgated thereunder.
