(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; (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 aggregate, represent a fundamental change in the information set forth in the 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 the undertakings set forth in paragraphs (i) and (ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act, 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, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in this 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 may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions described under Item 6 above, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities 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 Securities Act and will be governed by the final adjudication of such issue. II-4 SIGNATURES Pursuant to the requirements of the Securities Act, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing this Post-Effective Amendment on Form S-8 to Form S-4 Registration Statement and has duly caused this Amendment to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Houston, the State of Texas, on May 26, 1999.

                (As Amended and Restated Effective July 1, 1995)


                                Sixth Amendment


     The Benefits Committee of Houston Industries Incorporated, having reserved
the right under Section 10.3 of the Houston Industries Incorporated Savings
Plan, as amended and restated effective July 1, 1995, and thereafter amended
(the "Plan"), to amend the Plan, does hereby amend the Plan as follows:

     1.  Effective as of April 1, 1999, or such later date as prescribed by
paragraph 2 hereof, Section 8.2 of the Plan is hereby amended in its entirety as
follows:

     "8.2  Diversification Election:

          (a) Each Participant who has (i) completed at least ten years of
     participation in the Plan and the Prior Plan and (ii) attained age 55
     (hereinafter, a "Qualified Participant") may elect within 90 days after the
     close of each Plan Year in the initial election period (as defined herein),
     to direct the investment of up to 25% of the sum of the balances in such
     Participant's ESOP Account and Employer Matching Account (to the extent
     such portion exceeds the amount to which a prior election to diversify
     under this Section 8.2(a) applies) into any or all Investment Funds with
     the exception of the HI Common Stock Fund, and such election shall be
     effective as of the last Valuation Date in March.  In each Plan Year after
     the initial election period, the percentage shall be 50% instead of 25%.
     The initial election period means the five Plan Year period beginning with
     the first Plan Year in which the Participant first became a Qualified
     Participant.

          (b) Each Participant may elect, once each calendar year in the manner
     and subject to such rules, procedures and overriding Plan limits as
     specified by the Committee, to direct the investment of up to 50% of the
     sum of the balances in the Participant's ESOP Account and Employer Matching
     Account which are attributable to Employer Contributions made with respect
     to periods on or after April 1, 1999 into any or all Investment Funds with
     the exception of the HI Common Stock Fund; provided, however, that at least
     50% of the aggregate sum of the balances in the ESOP Accounts and Employer
     Matching Accounts of all Participants must be invested in Company Stock.
     Such election shall be effective as soon as reasonably practicable
     following receipt of the election to diversify, but in no event


     shall the election be effective earlier than the close of business on the
     Valuation Date on which the election is received. Any amounts so
     diversified and reinvested may subsequently be directed by the Participant
     in the same manner as amounts in the Participant's After-Tax and Pre-Tax
     Contribution Accounts as described in Section 8.1, except that none of the
     amounts so diversified may be invested in the HI Common Stock Fund."

     2.  This Amendment shall not become effective unless and until (i) the
Internal Revenue Service issues a favorable determination letter indicating that
the Amendment will not adversely affect the Plan's qualification under Section
401(a) of the Internal Revenue Code of 1986 (the "Code") or the Plan's
classification as an "Employee Stock Ownership Plan," as defined in Section
4975(e)(7) of the Code, and (ii) the Benefits Committee (by formal written
resolution) elects to implement the terms of the Amendment on or after April 1,
1999.

     IN WITNESS WHEREOF, the Company has caused these presents to be executed by
its duly authorized officer in a number of copies, all of which shall constitute
one and the same instrument, which may be sufficiently evidenced by any executed
copy hereof, this 29th day of April, 1999, but effective as of the date
specified herein.

        "(c)  In addition and with respect to only those Participants who
     previously had an account established under the STP Savings Plan (as
     defined in Section 8.4) as of October 1, 1997, prior to their employment
     after such date by an Employer covered by this Plan, the period of
     employment of such Participant by STP shall be deemed to be employment by
     an Affiliate hereunder for purposes of eligibility and vesting and shall be
     calculated as provided in Section 3.10(a) above."

                                       1


          4. The second paragraph of Section 4.1 of the Plan is hereby amended,
effective as of January 1, 1999, to read as follows:

        "The Employer shall also make an Employer Matching Contribution (subject
     to adjustments for forfeitures and limitations on annual additions as
     elsewhere specified in the Plan) in the amount, if any, necessary to result
     in a total allocation under Article V to each Participant's Prior Plan and
     ESOP Accounts of not less than 75% of the total of his Pre-Tax Basic
     Contribution and After-Tax Basic Contribution for the Plan Year in the case
     of HII Participants. Further, the Employer shall make an additional ESOP
     Contribution and/or Employer Matching Contribution, if necessary, to make
     the allocation required under Section 5.3(d)(ii) with respect to dividends
     used to repay an Exempt Loan. In addition, in its discretion, the Employer
     may make an additional Employer Matching Contribution in an amount
     determined by the Board of Directors of the Employer and communicated to
     the Participants within 90 days following the close of the applicable Plan
     Year."

          5. The fourth sentence of Section 4.2 of the Plan is hereby amended,
effective as of January 1, 1998, to read as follows:

     "A Participant's Pre-Tax Contributions under this Plan and all other plans,
     contracts or arrangements of the Employer shall not exceed a maximum
     contribution of $10,000 (as adjusted by the Secretary of the Treasury) for
     each calendar year."

          6. The definition of "Highly Compensated Employee" in Section 4.5(b)
of the Plan is hereby amended, effective as of January 1, 1997, by inserting the
following as new paragraphs following the fourth paragraph thereto:

        "Effective January 1, 1997, 'Highly Compensated Employee' shall mean any
     Employee and any employee of an Affiliate who is a highly compensated
     employee under Section 414(q) of the Code, including any Employee and any
     employee of an Affiliate who:

             (i) was a 5% owner during the current Plan year or prior Plan Year;
     or

             (ii) received Compensation during the Plan Year (as defined in
     Section 5.5(d)(6) in excess of $80,000 or such other dollar amount as may
     be prescribed by the Secretary of the Treasury or his delegate and, if
     elected by the Employer, was in the 'top-paid group' (the top 20% of
     payroll) for the Plan Year, excluding Employees described in Code Section
     414(p)(8).

                                       2


          In determining an Employee's status as a Highly Compensated Employee
     within the meaning of Section 414(q), the entities set forth in Treasury
     Regulation Section 1.414(q)-1T Q&A-6(a)(1) through (4) must be taken into
     account as a single employer.

          A former Employee shall be treated as a Highly Compensated Employee if
     (1) such former Employee was a Highly Compensated Employee when he
     separated from Service, or (2) such former Employee was a Highly
     Compensated Employee in Service at any time after attaining age 55."

          7. The sixth paragraph of Section 4.5 of the Plan is hereby deleted,
effective as of January 1, 1997.

          8. Section 4.8 of the Plan is hereby amended in its entirety,
effective as of January 1, 1997, to read as follows:

          "4.8 Excess Pre-Tax Contributions: As soon as possible following the
     end of the Plan Year, the Committee shall determine whether either of the
     tests contained in Section 4.5 were satisfied as of the end of the Plan
     Year, and any excess Pre-Tax Contributions, plus any income and minus any
     loss attributable thereto, of those Participants who are among the Highly
     Compensated Employees shall be distributed to such Participants in the
     manner provided below based on the amount of Pre-Tax Contributions. In
     addition, the Employer Contribution made with respect to such excess Pre-
     Tax Contributions shall be forfeited and applied to reduce future Employer
     Contributions otherwise required under Section 4.1. Such income shall
     include the allocable gain or loss for the Plan Year only.

          The amount of any excess Pre-Tax Contributions to be distributed to a
     Participant shall be reduced by Excess Deferrals previously distributed to
     him pursuant to Section 4.2 for the taxable year ending in the same Plan
     Year.  All excess Pre-Tax Contributions shall be returned to the
     Participants no later than the last day of the following Plan Year.  The
     excess Pre-Tax Contributions, if any, of each Participant who is among the
     Highly Compensated Employees shall be determined by computing the maximum
     Actual Deferral Percentage which each such Participant may defer under (a)
     or (b) of Section 4.5 and then reducing the Actual Deferral Percentage of
     some or all of such Participants through the distribution of such excess
     Pre-Tax Contributions, on the basis of the amount of Pre-Tax Contributions
     of such Participants, as necessary to reduce the overall Actual Deferral
     Percentage for eligible Participants who are among the Highly Compensated
     Employees to a level which satisfies either (a) or (b) of Section 4.5,
     according to the following procedures:

                                       3


               (a) the Pre-Tax Contributions of the Highly Compensated Employee
          or Employees with the highest dollar amount of Pre-Tax Contributions
          shall be reduced to equal the dollar amount of the Pre-Tax
          Contributions of the Highly Compensated Employee or Employees with the
          next highest dollar amount of Pre-Tax Contributions;

               (b) the reduction amount determined in clause (a) shall be
          distributed to the Highly Compensated Employee or Employees who had
          the highest dollar amount of Pre-Tax Contributions prior to such
          reduction; and

               (c) the procedures in clause (a) and (b) shall be repeated until
          the total excess Pre-Tax Contributions are distributed and compliance
          is achieved with (a) or (b) of Section 4.5.

     If these distributions are made, the Actual Deferral Percentage is treated
     as meeting the nondiscrimination test of Section 401(k)(3) of the Code
     regardless of whether the Actual Deferral Percentage, if recalculated after
     distributions, would satisfy Section 401(k)(3) of the Code.  The above
     procedures are used for purposes of recharacterizing excess Pre-Tax
     Contributions under Section 401(k)(8)(A)(ii) of the Code.  For purposes of
     Section 401(m)(9) of the Code, if a corrective distribution of excess Pre-
     Tax Contributions has been made, or a recharacterization has occurred, the
     Actual Deferral Percentage for Highly Compensated Employees is deemed to be
     the largest amount permitted under Section 401(k)(3) of the Code.

          The income or loss attributable to the Participant's excess Pre-Tax
     Contributions for the Plan Year shall be determined by multiplying the
     income or loss attributable to the Participant's Pre-Tax Contribution
     Account balance for the Plan Year by a fraction, the numerator of which is
     the excess Pre-Tax Contribution and the denominator of which is the
     Participant's total Pre-Tax Contribution Account balance.  Excess Pre-Tax
     Contributions shall be treated as Annual Additions under Section 5.5 of the
     Plan."

          9. Section 4.9 of the Plan is hereby deleted and the following
Sections renumbered accordingly, effective as of January 1, 1997, along with all
current references in the Plan affected by such deletion.

          10. The second paragraph of Section 4.11 (prior to renumbering) of the
Plan is hereby deleted, effective as of January 1, 1997.

                                       4


          11. Section 4.12 (prior to renumbering) of the Plan is hereby amended
in its entirety, effective as of January 1, 1997, to read as follows:

          "4.12 Treatment of Excess Aggregate Contributions or ESOP
     Contributions: If neither of the tests described above in Section 4.11 are
     satisfied with respect to either Aggregate Contributions or ESOP
     Contributions, the excess Aggregate Contributions or ESOP Contributions (as
     applicable), plus any income and minus any loss attributable thereto, shall
     be forfeited or, if not forfeitable, shall be distributed no later than the
     last day of the Plan Year following the Plan Year in which such excess
     Aggregate Contributions or ESOP Contributions (as applicable) were made.
     Such income shall include the allocable gain or loss for the Plan Year
     only. The income or loss attributable to the Participant's excess Aggregate
     Contributions or ESOP Contributions (as applicable) for the Plan Year shall
     be determined by multiplying the income or loss attributable to the
     Participant's Account for the Plan Year by a fraction, the numerator of
     which is the excess Aggregate Contribution or ESOP Contributions (as
     applicable), and the denominator of which is the Participant's total
     Account balance. Excess Aggregate Contributions or ESOP Contributions shall
     be treated as Annual Additions under Section 5.5 of the Plan.

          The excess Aggregate Contributions or ESOP Contributions (as
     applicable), if any, of each Participant who is among the Highly
     Compensated Employees shall be determined by computing the maximum
     Contribution Percentage under (a) or (b) of Section 4.11 and then reducing
     the Contribution Percentage of some or all of such Participants whose
     Contribution Percentage exceeds the maximum through the distribution or
     forfeiture of the excess Aggregate Contributions or ESOP Contributions (as
     applicable), on the basis of the amount of such excess contributions
     attributable to such Participants, as necessary to reduce the overall
     Contribution Percentage for eligible Participants who are among the Highly
     Compensated Employees to a level which satisfies either (a) or (b) of
     Section 4.11, according to the following procedures:

               (a) the Aggregate Contributions or ESOP Contributions (as
          applicable) of the Highly Compensated Employee or Employees with the
          highest dollar amount of such contributions shall be reduced to equal
          the dollar amount of the Aggregate Contributions or ESOP Contributions
          (as applicable) of the Highly Compensated Employee or Employees with
          the next highest dollar amount of such contributions;

               (b) the reduction amount determined in clause (a) shall be
          forfeited by or, if not forfeitable, distributed to the Highly
          Compensated Employee or Employees who had the highest dollar

                                       5


          amount of Aggregate Contributions or ESOP Contributions (as
          applicable) prior to such reduction; and

               (c) the procedures in clause (a) and (b) shall be repeated until
          the total excess Aggregate Contributions or ESOP Contributions (as
          applicable) are forfeited and/or distributed and compliance is
          achieved with (a) or (b) of Section 4.11.

     If these forfeitures and/or distributions are made, the Contribution
     Percentage is treated as meeting the nondiscrimination test of Section
     401(m)(2) of the Code regardless of whether the Contribution Percentage, if
     recalculated after such forfeitures and/or distributions would satisfy
     Section 401(m)(2) of the Code.  For purposes of Section 401(m)(9) of the
     Code, if a corrective distribution of excess Aggregate Contributions or
     ESOP Contributions (as applicable) has been made, the Contribution
     Percentage for Highly Compensated Employees is deemed to be the largest
     amount under Section 401(m)(2) of the Code.

     For each Participant who is a Highly Compensated Employee, the amount of
     excess Aggregate Contributions or ESOP Contributions (as applicable) is
     equal to the total Employer Contributions and After-Tax Contributions on
     behalf of the Participant (determined prior to the application of this
     paragraph) minus the amount determined by multiplying the Participant's
     actual contribution ratio (determined after application of this paragraph)
     by his Compensation used in determining such ratio.  The individual ratios
     and Contribution Percentages shall be calculated to the nearest 1/100 of 1%
     of the Employee's Compensation, as such term is used in paragraph (b) of
     Section 4.11."

          12. Section 4.13 (prior to renumbering) of the Plan is hereby deleted,
effective as of January 1, 1997.

          13. Section 5.5(c) of the Plan is hereby amended, effective as of
January 1, 2000, by adding the following to the end thereof:

     "5.  Termination of Section 5.5(c)

          From and after January 1, 2000, the provisions of this Section 5.5(c)
          shall no longer apply."

                                       6


          14. Clause (A) of Section 5.5(d)(5) of the Plan is hereby amended,
effective as of January 1, 1995, to read as follows:

          "A. $30,000, as adjusted by the Secretary of the Treasury or his
     delegate; or"

          15. The last sentence of the last paragraph of Section 5.5(d)(6) of
the Plan is hereby amended, effective as of January 1, 1998, to read as follows:

     "Notwithstanding anything to the contrary in this definition, Compensation
     shall include any and all items which may be included in Compensation under
     Code Section 415(c)(3), including effective January 1, 1998, (i) any
     elective deferral (as defined in Code Section 402(g)(3) and (ii) any amount
     which is contributed or deferred by the Employer at the election of the
     Employee and which is not includible in the gross income of the Employee by
     reason of Code Section 125 or 457."

          16. The first paragraph of Section 6.1 of the Plan is hereby amended,
effective January 1, 1999, to read as follows:

          "6.1 Termination of Service: In the event of a termination of Service
     on or after the Effective Date but prior to January 1, 1999, the provisions
     of Section 6.1 of the Plan as in effect immediately prior to this Amendment
     shall govern. In the event of a termination of Service on or after January
     1, 1999, any Participant for any reason other than disability, Retirement
     on or after Retirement Date or death, a Participant shall, subject to the
     further provisions of the Plan, be entitled to receive 100% of the values
     in his Pre-Tax Contribution Account and After-Tax Contribution Account,
     plus a portion of his Employer Matching Account and ESOP Account determined
     by reference to his number of years of Vesting Service and the following
     table:

                                  Vesting
     Years of Vesting Service    Percentage
     ------------------------    ----------
     Less than 2                     0%
     2 but less than 3              25%
     3 but less than 4              50%
     4 but less than 5              75%
     5 and more                    100%"

          17. The first paragraph of Section 6.6 of the Plan is hereby amended,
effective as of January 1, 1998, by replacing any reference to "$3,500" with
"$5,000."

                                       7


          18. Section 6.6(b) of the Plan is hereby amended in its entirety,
effective as of January 1, 1999, to read as follows:

          "(b) As a distribution in kind of the shares held for his Account in
     the HI Common Stock Fund and the ESOP Fund. If Company Stock acquired with
     the proceeds of an Exempt Loan and available for distribution consists of
     more than one class, a Participant shall receive substantially the same
     proportion of each such class to the extent the distribution is a
     distribution from the ESOP Fund. A Participant may elect to receive any
     percentage, up to 100%, of the vested portion of his Accounts in the HI
     Common Stock Fund and the ESOP Fund in whole shares of Company Stock, and
     the remaining HI Common Stock Fund balance, ESOP Fund balance and other
     Investment Fund balances in cash. If a Participant elects to receive the
     entire vested portion of his Accounts in the HI Common Stock Fund and the
     ESOP Fund in whole shares of Company Stock, such Participant shall be
     entitled to receive a number of whole shares of Company Stock plus the cash
     value of any partial shares of Company Stock necessary to equal the sum of
     (i) the value in the HI Common Stock Fund held in his Pre-Tax Contribution
     Account and/or his After-Tax Contribution Account as of the Valuation Date
     specified in Section 6.8, and (ii) the vested portion of the value in the
     HI Common Stock Fund held in his Employer Matching Account and the vested
     portion of the value in the ESOP Fund held in his ESOP Account as of such
     Valuation Date. If a Participant elects to receive a percentage which is
     less than 100% of the vested portion of his Accounts in the HI Common Stock
     Fund and the ESOP Fund in whole shares of Company Stock, then the result
     obtained from the preceding formula shall be multiplied by such percentage
     to obtain the number of whole shares of Company Stock and cash for partial
     shares of Company Stock to be distributed to such Participant."

          19. The third paragraph of Section 6.9 of the Plan is hereby amended,
effective as of January 1, 1999, by replacing any reference to "suspense" with
"separate."

          20. Section 6.10 of the Plan is hereby amended in its entirety,
effective as of January 1, 1999, to read as follows:

          "6.10 Required Minimum Distributions: Notwithstanding any provision of
     this Plan to the contrary, prior to January 1, 1999, for a Participant
     attaining age 70 1/2 prior to January 1, 1999, any benefits to which a
     Participant is entitled shall commence not later than the April 1 following
     the calendar year in which the Participant attains age 70 1/2, whether or
     not such Participant's employment had terminated in such year. Effective
     January 1, 1999, for a Participant attaining age 70 1/2 after December 31,
     1998, any benefits to which a Participant is entitled shall commence not
     later than the April 1 following the latter of (i) the calendar year in
     which the Participant attains age 70 1/2 or (ii) the calendar year in which
     the

                                       8


     Participant's employment terminates (provided, however, that clause (ii) of
     this sentence shall not apply in the case of a Participant who is a "five-
     percent owner" (as such term is defined in Section 416 of the Code) with
     respect to the Plan Year ending in the calendar year in which such
     Participant attains age 70 1/2). If a Participant is receiving
     distributions from his Accounts on January 1, 1999 pursuant to this Section
     6.10 as in effect prior to January 1, 1999, but would not be required to
     receive distributions under this Section 6.10 as in effect on January 1,
     1999, then the Participant may elect to cease distributions from his
     Accounts until the April 1 following the end of the calendar year in which
     such Participant terminates employment. Distributions under this Section
     6.10 shall be at least equal to the required minimum distributions under
     Section 401(a)(9) of the Code; provided, however, that any installment
     distributions pursuant to this Section 6.10 for Participants who have not
     terminated employment shall be made over a period not to exceed ten (10)
     years."

          21. The last sentence of Section 7.3 of the Plan is hereby amended,
effective as of January 1, 1999, to read as follows:

     "Except as provided in Section 7.4 and under Article VI, no withdrawals
     shall be permitted from a Participant's Pre-Tax Contribution Account,
     Employer Matching Account or ESOP Account."

          22. The last sentence of Section 7.4(b) of the Plan is hereby amended,
effective as of January 1, 1999, to read as follows:

     "A Borrower may repay an outstanding loan in full at any time."

          23. The first sentence of Section 12.4 of the Plan is hereby amended,
effective as of August 5, 1997, to read as follows:

     "Except as otherwise provided below and with respect to certain judgments
     and settlements pursuant to Section 401(a)(13) of the Code, no interest,
     right or claim in or to the part of the Trust Fund attributable to the Pre-
     Tax Contribution Account, the After-Tax Contribution Account, the Employer
     Matching Account or the ESOP Account of any Participant, or any
     distribution of benefits therefrom, shall be assignable, transferable or
     subject to sale, mortgage, pledge, hypothecation, commutation,
     anticipation, garnishment, attachment, execution, claim or levy of any
     kind, voluntary or involuntary (excluding a levy on an Account other than a
     Pre-Tax Contribution Account for taxes filed upon the Plan by the Internal
     Revenue Service), including without limitation any claim asserted by a
     spouse or former spouse of any Participant, and the Trustee shall not
     recognize any attempt to assign, transfer, sell, mortgage, pledge,
     hypothecate, commute or anticipate the same."

Reliant Energy, Incorporated

Houston, Texas  77002

Ladies and Gentlemen:

     As set forth in Post-Effective Amendment No. 3 on Form S-8 (the "Post-
Effective Amendment") to the Registration Statement on Form S-4 (No. 333-11329)
to be filed by Reliant Energy, Incorporated, a Texas corporation (formerly named
Houston Industries Incorporated and herein called the "Company"), with the
Securities and Exchange Commission under the Securities Act of 1933, as amended,
relating to up to 7,000,000 shares (the "Shares") of common stock, without par
value, of the Company (the "Common Stock") and associated rights to purchase
Series A Preference Stock, without par value, of the Company (the "Rights"),
which may be offered and sold from time to time pursuant to the Reliant Energy,
Incorporated Savings Plan (the "Savings Plan"), certain legal matters in
connection with the Shares subject to original issuance by the Company and the
Rights associated therewith are being passed upon for you by us.  At your
request, this opinion is being furnished to you for filing as Exhibit 5.1 to the
Post-Effective Amendment.

     In our capacity as your counsel in the connection referred to above, we
have examined the Company's Restated Articles of Incorporation and Amended and
Restated Bylaws, each as amended to date, and the Amended and Restated Rights
Agreement dated as of August 6, 1997 between the Company and Chase Bank of
Texas, National Association (the "Rights Agreement") and have examined
originals, or copies certified or otherwise identified, of corporate records of
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.

     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 incorporated and validly existing in
   good standing under the laws of the State of Texas.

     2.  When and to the extent originally issued by the Company to the Trustee
   under the Savings Plan from time to time upon purchase by the Trustee and
   payment therefor in accordance with the terms and provisions of the Savings
   Plan, such Shares will be duly authorized, validly issued, fully paid and
   nonassessable.

     3.  The issuance of the Rights associated with the Shares referred to in
   paragraph 2 above 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 in paragraph 2 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.

     This opinion is limited to the original issuance of Shares and Rights by
the Company and does not cover shares of Common Stock and related Rights
delivered by the Company out of shares and related Rights reacquired by it or
purchased other than from the Company by the Trustee under the Savings Plan.

     We are members of the Texas Bar and the opinions set forth above are
limited in all respects to matters of Texas law as in effect on the date hereof.

                                             Very truly yours,


                                             Baker & Botts, L.L.P.


                                                                    EXHIBIT 23.1
