EXHIBIT 10(u)(12) RELIANT ENERGY, INCORPORATED RETIREMENT PLAN (As Amended and Restated Effective January 1, 1999) Second Amendment The Benefits Committee of Reliant Energy, Incorporated, having reserved the right under Section 15.1 of the Reliant Energy, Incorporated Retirement Plan, as amended and restated effective January 1, 1999 (the "Plan"), to amend the Plan, does hereby amend the Plan, as follows: 1. Effective as of January 1, 1999, the first sentence of Section 1.21 is hereby amended to read as follows: "Any person employed by an Employer, and including (i) any individual on Disability Leave of Absence and (ii) any Leased Employee performing services for an Employer." 2. Effective as of January 1, 1999, the following new definition of "Hour of Service" is hereby added as Section 1.25 of the Plan, and all subsequent definitions shall be redesignated and all affected references are hereby amended accordingly: "1.25 Hour of Service: For purposes of Section 11.7: (a) An Hour of Service shall be credited to an Employee for each hour for which an Employee is directly paid, or entitled to payment, by the Employer or an Affiliate for the performance of duties during the applicable computation period. Such hours shall be credited to the Employee for the computation period or periods in which the duties were performed. (b) An Hour of Service shall be credited to an Employee for each hour for which back pay, irrespective of mitigation of damages, has been either awarded or agreed to by the Employer or an Affiliate. These hours shall be credited to the Employee for the computation period or periods to which the award or agreement pertains rather than the computation period in which the award, agreement, or payment is made. Hours of Service shall not be credited to an Employee under both paragraphs (a) and (b) of this Section. (c) In addition to Hours of Service credited in paragraphs (a) and (b) of this Section, an Hour of Service shall be credited to an Employee for each hour for which such Employee is directly or indirectly paid, or entitled to such payment by the Employer or an Affiliate for reasons (such as vacation or sickness) other than for the performance of duties during the applicable computation period. For purposes of this paragraph (c), irrespective of whether such hours have accrued in other computation periods, such hours shall be counted in the computation period in which either payment is actually made or amounts payable to the Employee come due. For purposes of this paragraph (c), Hours of Service shall be determined by dividing the payments received or due for reasons other than the performance of duties by the lesser of (i) the Employee's most recent hourly rate of compensation for the performance of duties or (ii) the Employee's average hourly rate of compensation for the performance of duties for the most recent computation period in which the Employee completed more than 500 Hours of Service. (d) The number of Hours of Service to be credited to an Employee shall be determined in accordance with Department of Labor Regulation Sections 2530.200b-2(b) and (c) (Title 29 Code of Federal Regulations Part 2530). Hours of Service shall also include any hours required to be credited by federal law other than the ERISA or the Code, but only under the conditions and to the extent so required by such federal law. (e) Hours of Service will be credited for employment with other members of an affiliated service group (under Section 414(m)), a controlled group of corporations (under Section 414(b)), or a group of trades or businesses under common control (under Section 414(c)), of which the adopting Employer is a member." 3. Effective as of January 1, 1999, the following new definition of "Leased Employee" is hereby added as Section 1.28 (prior to the redesignation in Paragraph 2 herein) of the Plan, and all subsequent definitions shall be redesignated and all affected references are hereby amended accordingly: "1.28 Leased Employee: Each person who is not an employee of the Employer or an Affiliate but who performs services for the Employer or an Affiliate pursuant to a leasing agreement (oral or written) between the Employer or an Affiliate and any leasing organization, provided that such person has performed such services for the Employer or an Affiliate or for related persons (within the meaning of Section 144(a)(3) of the Code) on a substantially full-time basis for a period of at least one year and such services are performed under primary direction or control by the Employer or an Affiliate. The term 'Leased 2 Employee' shall also include any individual who is deemed to be an employee of the Employer under Section 414(o) of the Code. Notwithstanding the preceding sentences, if individuals described in the preceding sentences constitute less than 20% of the Employer's nonhighly compensated work force within the meaning of Section 414(n)(5)(C)(ii) of the Code, the Plan shall not treat an individual as a Leased Employee if the leasing organization covers the individual in a money purchase pension plan providing immediate participation, full and immediate vesting and a nonintegrated contribution formula equal to at least 10% of the individual's annual compensation as defined in Section 415(c)(3) of the Code, but including amounts contributed by the Employer pursuant to a salary reduction agreement which are excludable from the individual's gross income under Section 125, 402(a)(8), 402(h) or 403(b) of the Code. If any Leased Employee shall be treated as an Employee of the Employer, however, contributions or benefits provided by the leasing organization which are attributable to services of the Leased Employee performed for the Employer shall be treated as provided by the Employer." 4. Effective as of January 1, 1999, the first sentence of Section 5.1 of the Plan is hereby amended to read as follows: "A Member shall be fully vested in his Pension upon completion of five years of Vesting Service, or, if earlier, upon the later of (a) the attainment of age 65 or (b) the fifth anniversary of the date he commenced participation in the Plan." 5.

Effective as of January 1, 2000, Section 9.2(c) of the Plan is hereby amended to read as follows: "(c) Notwithstanding any provision herein to the contrary, if the Actuarial Equivalent value of a Death Benefit payable on behalf of a Member does not exceed Five Thousand Dollars ($5,000), then such Death Benefit shall be paid to the Spouse or other Beneficiary, as applicable, in a cash lump sum as soon as administratively practicable after the Member's death." 8.
