Agreement, at the Closing, the Seller agrees to sell, convey, assign, transfer and deliver to the

Subject to the terms and conditions of this Agreement, in exchange for the Company Interests and
the REST and RETR Interest, the Purchaser agrees to deliver to the Seller, and the Seller agrees to
accept, the Purchase Price, in cash, without deduction or setoff of any kind, which delivery will

tax purposes, shall be allocated among the assets of the Company, the Retail Subsidiaries, REST and
RETR in accordance with a schedule to be prepared by the Purchaser using the allocation method
provided by Section 1060 of the Code and the regulations thereunder and consistent with any fair

of Section 1060 of the Code. In that regard, the Purchaser shall provide the Seller with the
Purchaser’s proposed allocation as soon as practicable after, and in no event later than 90 days

days following delivery of the Proposed Allocation Schedule during which to notify the Purchaser in
writing (an “Allocation Notice of Objection”) of any objections to the Proposed Allocation
Schedule, setting forth in reasonable detail the basis of its objections. If the Seller fails to

(i) for sixty (60) days after the date the Purchaser receives the Allocation Notice of Objection,
the Seller and the Purchaser will use their commercially reasonable efforts to agree on the
allocations and (ii) failing such agreement within sixty (60) days of such notice, the matter will

               (b) Any amounts remaining in dispute at the conclusion of such 60 day period that were
properly included in the Allocation Notice of Objection (the “Unresolved Allocation
Changes”) shall be submitted to KPMG LLP or such other international accounting or

Expert shall be instructed to determine its best estimate of the allocation schedule based on its
determination of the Unresolved Allocation Changes and provide a written description of the basis
for its determination of the allocations therein within 45 days after the matter has been submitted
to the Expert, which written determination shall be final, binding and conclusive on the Parties
and shall be included in the Final Allocation Schedule. Each of the Parties shall furnish, at its
own expense, the Expert and the other Party with such documents and other written information as
the Expert may request. The fees and expenses of the Expert shall be borne 50 percent by the
Seller and 50 percent by the Purchaser. Each Party will bear the costs of its own counsel,
witnesses (if any) and employees.

               (c) The Parties agree (i) to be bound by the Final Allocation Schedule for purposes of
determining any Taxes, (ii) to prepare and file their Tax Returns on a basis consistent with the
Final Allocation Schedule, and (iii) not to take any position inconsistent with the Final
Allocation Schedule on any applicable Tax Return or in any proceeding before any Tax Authority.
The Parties will revise the Final Allocation Schedule to the extent necessary to reflect any
payment made pursuant to Section 7.7 or Section 10.2. In the case of any such
payment, the Purchaser shall prepare and deliver to the Seller a revised Final Allocation Schedule,
and the Parties hereto shall follow the procedures outlined above with respect to review, dispute
and resolution in respect of such revision.

               (e) Each of the Subject Companies, REST and RETR is treated as a partnership or an entity that

was part of the Seller’s consolidated tax filings, in each case for United States federal income

thereof) ending after the Closing Date as a result of any: (A) change in method of accounting for a

          Section 4.9 Employee Benefits; ERISA. 

               (a) Section 4.9(a) of the Seller Disclosure Letter sets forth a true, correct and
complete list, as of the date hereof, of all Seller Affiliate Plans (as defined below). No
Business Employee is entitled to, or may become eligible to receive, any benefit from a Plan (as
defined below) other than a Seller Affiliate Plan. Seller has made available to the Purchaser
copies (including amendments) in the Seller data room of (i) each of the Seller Affiliate Plans,
including any plan documents, trust agreements, annuity contracts, insurance contracts or other
funding documents related to a Seller Affiliate Plan, (ii) the latest determination letter obtained
from the Internal Revenue Services (“IRS”) with respect to any Seller Affiliate Plan
intended to be qualified or exempt under Section 401 or 501 of the Code, (iii) the most recent
annual report (Form 5500, with all applicable attachments), (iv) the most recent actuarial report,
and (v) census data for the Business Employees for each Seller Affiliate Plan. As used in this
Agreement, “Seller Affiliate Plan” shall mean any Plan (as defined below) sponsored by the
Seller or any other trade or business (an “ERISA Affiliate”) that, together with the Seller
would be treated as a single employer under Section 4001(b) of the Employee Retirement Income
Security Act of 1974, as amended (“ERISA”), in any case that are currently in effect for
the benefit of any Business Employee or any other Plan to which the Subject Companies have any
liability. In addition, Section 4.9(a) of the Seller Disclosure Letter identifies each
Seller Affiliate Plan that is sponsored or maintained solely for the benefit of the Business
Employees or in respect of which Purchaser or the Subject Companies shall maintain or assume any
liability on or after the Closing Date (collectively, the “Assumed Benefit Plans”).
“Plans” shall mean all material “employee benefit plans” as defined by Section 3(3) of
ERISA, all material specified fringe benefit plans as defined in Section 6039D of the Code, and all
other material bonus, incentive compensation, deferred compensation, profit sharing, stock option,

leave, fringe benefit, or welfare plan, and any other material employee compensation or benefit
plan, agreement or policy.

               (b) Neither the Seller nor its ERISA Affiliates contribute to, have an obligation to
contribute to, or have ever contributed to, or ever had an obligation to contribute to, any
multiemployer plan (within the meaning of Section 3(37) of ERISA). No Assumed Benefit

25

 

Plan is a “defined benefit plan” as defined in Section 3(35) of ERISA or any other plan
subject to the funding requirements of Section 412 of the Code or Section 302 of Title IV of ERISA.

               (c) All Seller Affiliate Plans and related trust agreements are and have been maintained in
compliance both as to form and operation with all Laws, including the Code and ERISA, except where
such non-compliance would not reasonably be expected to result in a Subject Company liability that
is material to the Subject Companies, taken as a whole. A favorable determination letter as to
qualification under Section 401 of the Code has been issued with respect to any Seller Affiliate
Plan intended to be qualified under Section 401 of the Code, and the related trust has been
determined to be exempt from taxation under Section 501 of the Code. To the Seller’s Knowledge, no
events or circumstances have occurred that would adversely affect the qualified status of any such
plans or trusts.

               (d) No assets of the Subject Companies are or reasonably could be expected to be subject to a
lien arising under the Code or ERISA associated with any Plan and the Subject Companies do not have
any liability and do not reasonably expect to have any potential liability to the Pension Benefit
Guaranty Corporation or otherwise under Title IV of ERISA.

               (e) With respect to each Assumed Benefit Plan, (i) there have been no non-exempt “prohibited
transactions” (as defined in Section 406 of ERISA or Section 4975 of the Code), (ii) no “fiduciary”
(as defined in Section 3(21) of ERISA) has any liability for breach of fiduciary duty or any other
failure to act or comply in connection with the administration or investment of the assets of such
Assumed Benefit Plan, (iii) no action, investigation, suit, proceeding, hearing or claim with
respect to the assets thereof (other than routine claims for benefits) is pending or threatened,
and neither the Subject Companies nor the Seller have any knowledge of any facts that would give
rise to or could reasonably be expected to give rise to any such action, suit or claim, and (iv)
all contributions (including all employer contributions and employee salary reduction
contributions) that are due have been made within the time periods prescribed by ERISA and the
Code, and all contributions for any period ending on or before the Closing Date that are not yet
due have been made or properly accrued. No Assumed Benefit Plan has any material unfunded
liability not accurately reflected on the Retail Financial Statements in accordance with GAAP.

               (f) No Continuing Employee has received or is entitled to receive employer-subsidized health
care or any other non-pension benefits with respect to employment by any Subject Company for more
than 31 days after his or her employment is terminated (other than as required by COBRA) and has
never been promised such employer-subsidized post-termination benefits with respect to employment
at any Subject Company.

               (g) None of the Assumed Benefit Plans provides any separation, severance, termination or
similar benefit or accelerates any vesting schedule or alters any benefit structure solely as a
result of a change in control of ownership within the meaning of any Assumed Benefit Plans or
Section 280G of the Code.

               (h) Except as would not individually or in the aggregate reasonably be expected to result in a
material liability to the Purchaser or the Subject Companies, taken as a

26

 

whole, no agreement,
program, contract, or other similar arrangement entered into by any of the Subject Companies that
is a “nonqualified deferred compensation plan” within the meaning of Code Section 409A(d)(1) and
any regulations promulgated thereunder provides for any payment or benefit that is subject to the
income acceleration, interest, or additional tax provisions of Code Section 409A.

          Section 4.10 Labor and Employment.

               (a) With respect to each Business Employee, none of the Subject Companies is a party to, nor
is bound by, the terms of any collective bargaining agreement or any other contract or bargaining
relationship with any labor organization or representative of employees. To the Seller’s
Knowledge, there are no union organization or decertification activities underway or threatened
involving employees of any Subject Company and no such activities have occurred within the past
three (3) years. To the Seller’s Knowledge, there are presently, and for the past two (2) years
there have been, no strikes, lockouts, organized work slowdowns, material unfair labor practice
charges, or other material labor disputes at any of the Subject Companies.

               (b) The Subject Companies are, and for the past twenty-four (24) months have remained, in
compliance with all Laws relating to labor relations and employment with respect to the Business
Employees, except where such non-compliance would not reasonably be expected to result in a Subject
Company liability that is material to the Subject Companies, taken as a whole.

               (c) To the Seller’s Knowledge, no Business Employee is in material violation of any term or
provision of any employment contract, confidentiality or other proprietary information disclosure
agreement or other contract relating to the right of any such Person to be employed or engaged by
any Subject Company.

               (d) To the Seller’s Knowledge, none of the employment policies or practices applicable to the
Business Employees are currently being audited or investigated by any Governmental Authority which
would reasonably be expected to result in a Subject Company liability that is material to the
Subject Companies, taken as a whole. To the Seller’s Knowledge there are no current charges,
claims, or demands filed with any Governmental Authority from any current or former Business
Employees regarding their employment or former employment at any of the Subject Companies which
would reasonably be expected to result in a Subject Company liability that is material to the
Subject Companies, taken as a whole.

               (e) Neither the execution and delivery of this Agreement or the documents contemplated hereby
by the Seller, the performance by the Seller of its obligations hereunder and thereunder, nor the
consummation of the transactions contemplated hereby and thereby will (i) materially increase or
enhance any benefits payable to a Business Employee under any Assumed Benefit Plan or (ii)
materially accelerate the time of payment or vesting, or increase the amount, of any compensation
due to any Business Employee under a Assumed Benefit Plan.

27

 

               (f) With respect to this transaction, any notice required of the Seller or its Affiliates
under any labor law or collective bargaining agreement has been or prior to Closing will be given,
and all bargaining obligations with any employee representative have been or prior to Closing will
be satisfied; provided, however, that the foregoing obligations apply only to employment actions
taken by the Seller or its Affiliates prior to Closing and do not apply to employment actions taken

          Section 5.2 Authority; Non-Contravention; Statutory Approvals; Compliance.

               (a) Authority. The Purchaser has all requisite limited liability company power and

the execution and delivery by the Purchaser of this Agreement or the consummation by it of the
transactions contemplated hereby. This Agreement has been duly executed and delivered by the
Purchaser and, assuming the due authorization, execution and delivery hereof by the Seller,
constitutes the valid and binding obligation of the Purchaser enforceable against it in accordance
with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium
and similar Laws of general applicability relating to or affecting creditors’ rights and to general
equity principles.

               (b) Non-Contravention. The execution and delivery of this Agreement by the Purchaser

notice to or authorization, consent or approval of, any Governmental Authority is necessary for the

right to terminate the Commitment Letter (other than as set forth therein). As of the date of this

other ML Arrangement Document by Guarantor or the Purchaser or any of their Affiliates. The
Purchaser has no Knowledge of any facts or circumstances (other than facts and circumstances
relating to any default by the Seller or its Subsidiaries under agreements with Merrill Lynch)that

any other ML Arrangement Document not being satisfied or (ii) the transaction contemplated in the
Merrill Lynch New Agreement not being consummated on a timely basis.

hereto as Exhibit R (“Advance Integration Agreement”).

Notwithstanding anything in this Agreement to the contrary, nothing in this Agreement shall be
deemed to restrict the ability of the Seller or any of its Subsidiaries (other than the Subject
Companies) to solicit any offer, bid or indication of interest with respect to, or to initiate or
engage in negotiations or enter into any agreement with any Person with respect to, or to take any
action to facilitate or effectuate, any merger, consolidation or sale or disposition of all or any

ARTICLE VII

ADDITIONAL AGREEMENTS

          Section 7.1 Access to Subject Companies Information. Upon reasonable notice, the Seller shall,
and shall cause the Subject Companies to, afford to the officers, directors, employees,
accountants, counsel, investment bankers, financial advisors and other representatives
(collectively, “Representatives”) of the Purchaser reasonable access, during normal
business hours throughout the period prior to and including the Closing Date, to all of the Subject
Companies’, REST’s and RETR’s properties, books, contracts, commitments and records and, during
such period, the Seller shall, and shall cause the Subject Companies to furnish to the Purchaser
and its Representatives, access to all information concerning the Subject Companies and their
respective directors and officers and such other matters as may be reasonably requested by the
Purchaser or its Representatives in connection with any filings, applications or approvals required
or contemplated by this Agreement and attend and cause the Subject Companies to attend periodic
meetings with the Purchaser as reasonably requested by the Purchaser. Notwithstanding the
foregoing, neither the Seller nor any of the Subject Companies shall be required to afford such
access if it would unreasonably disrupt the operations of such party or any of its Subsidiaries,
would cause a violation of any agreement to which such party or any of its Subsidiaries is a party
(provided that the Seller has used its reasonable best efforts to find an alternative way to
provide the access or information contemplated by this Section 7.1), cause a risk of a loss
of privilege to such party or any of its Subsidiaries or would constitute a violation of any
applicable Law. The Purchaser agrees to indemnify and hold the Seller and the Subject Companies
harmless from any and all claims and liabilities, including costs and expenses for loss, injury to
or death of any Representative of the Purchaser, and any loss, damage to or destruction of any
property owned by the Seller, any Subject Company or others (including claims or liabilities for
loss of use of any property) resulting directly or indirectly from the action or inaction of any of
the Representatives of the Purchaser during any visit to the business or property sites of the
Seller or any Subject Company prior to or including the Closing Date, whether pursuant to this
Section 7.1 or otherwise, INCLUDING ON ACCOUNT OF THE SOLE OR CONCURRENT NEGLIGENCE OF THE
SELLER, ITS AFFILIATES, OR ITS OFFICERS, DIRECTORS, EMPLOYEES OR AGENTS.

          Section 7.2 Confidentiality. Each Party shall, and shall cause its Affiliates and Representatives
to, hold in strict confidence all documents and information concerning the other furnished to it in
connection with the transactions contemplated by this Agreement in accordance with the
Confidentiality Agreement, dated November 3, 2008, entered into by and between the Seller and NRG
Energy, Inc. (the “Confidentiality Agreement”); provided, however, that either Party shall
be entitled to disclose the terms of this Agreement to any prospective purchaser of such Party (or,
in the case of the Seller, all or substantially all of the Seller’s wholesale business) that has
agreed to maintain the confidentiality of such information. From and after the Closing, for
purposes of the Confidentiality Agreement the Seller shall treat information regarding the Retail
Business that it considered to be confidential prior to the Closing as if it were confidential
information disclosed to the Seller by NRG Energy, Inc.

               (a) HSR Filings. The Parties shall, as soon as practicable, and, in any case, no
later than 10 Business Days after the date hereof, file or cause to be filed with the Federal Trade
Commission and the Department of Justice any notifications required to be filed under the HSR Act
and the rules and regulations promulgated thereunder with respect to the transactions contemplated
hereby. Neither Party shall make a filing without the consent of the other Party, not to be
unreasonably withheld. Each Party will use all reasonable best efforts to respond on a timely
basis to any requests for additional information made by either of such agencies.

               (b) FERC Filing. The Seller shall cause RE Supply to file with FERC an application to
withdraw its market-based rate authority within ten (10) days after the date hereof.

               (c) Other Regulatory Approvals. Each Party shall cooperate and use its reasonable
best efforts to prepare and file as soon as practicable all necessary documentation, to effect all
necessary applications, notices, petitions, filings and other documents, and to use reasonable best
efforts to obtain all necessary permits, consents, approvals and authorizations of all Governmental
Authorities necessary or advisable to obtain the Seller Required Statutory Approvals and the
Purchaser Required Statutory Approvals. The Parties further agree to use reasonable best efforts
to take any act, make any undertaking or receive any clearance or approval required by any
Governmental Authority or Law. Each of the Parties shall (i) respond as promptly as practicable to
any inquiries or requests received from any Governmental Authority for additional information or
documentation and (ii) not enter into any agreement with any Governmental Authority not to
consummate the transactions contemplated by this Agreement, except with the prior consent of the
other Party (which shall not be unreasonably withheld or delayed). Each of the Parties shall use
reasonable best efforts to avoid or eliminate each and every impediment under any antitrust,
competition, or trade or energy regulation Law that may be asserted by any Governmental Authority
with respect to the transactions contemplated hereby so as to enable the Closing Date to occur as
soon as reasonably possible. The steps involved in the preceding sentence (i) shall not include
proposing, negotiating or committing to affect, by consent decree, agreeing to a hold separate
order or otherwise, the sale, divestiture or disposition of any material assets or businesses of
the Purchaser and its Affiliates (including their respective Subsidiaries), taken as a whole, but
(ii) may include agreeing to limitations on its or their conduct or actions, other than as
described in clause (i) of this sentence or that would have a material impact on the business of
the Purchaser and its Affiliates, taken as a whole, as may be required in order to obtain the
Seller Required Statutory Approvals and the Purchaser Required Statutory Approvals as soon as
reasonably possible, to avoid the entry of, or to effect the dissolution of, any injunction,
temporary restraining order or other order in any suit or proceeding required in order to obtain
the Seller Required Statutory Approvals or the Purchaser Required Statutory Approvals, which would
otherwise have the effect of preventing or delaying the Closing Date beyond the Termination Date,
and defending through litigation on the merits, including appeals, any claim asserted in any court
by any party as required in order to obtain the Seller Required Statutory Approvals or the
Purchaser Required Statutory Approvals.

               (d) Notice of Actions. Each of the Parties shall (i) give the other Party prompt
notice of the commencement or threat of commencement of any Action by or before any Governmental
Authority with respect to this Agreement or any of the transactions contemplated

48

 

by this Agreement,
(ii) keep the other Party informed as to the status of any such Action or threat thereof, and (iii)
promptly inform the other Party of any communication to or from any Governmental Authority
regarding this Agreement or any of the transactions contemplated by this Agreement.

          Section 7.4 Consents. The Seller and the Purchaser agree to use reasonable best efforts to obtain
the Seller Required Consents and the Purchaser Required Consents, respectively, and any other third
party consents necessary to transfer the Company Interests or to transfer any contracts from the
Seller or its Affiliates to the Purchaser or the Subject Companies as contemplated hereby, and to
cooperate with each other in connection with the foregoing (it being understood and agreed that,
except as set forth in Section 7.15(b), neither the Seller nor the Purchaser shall be
required to expend any amounts or incur any liabilities in connection with obtaining any
third-party waivers, consents or approvals).

          Section 7.5 Public Announcements. The initial press release relating to this Agreement shall be a
joint press release and thereafter the Purchaser and the Seller shall consult with each other and
shall agree upon the text of any press release or public statement before issuing any press release
or otherwise making any public statements with respect to the transactions contemplated hereunder
and shall not issue any such press release or make any such public statement prior to such
consultation and agreement, except as may be required by Law or any listing agreement with, or the
rules of the NYSE, in which case commercially reasonable efforts to consult with the other Party
shall be made prior to such release or public statement. The Purchaser shall cause each of its
Affiliates to not issue any press release or make any public statement with respect to the
transactions contemplated hereunder unless the Purchaser has first consulted with the Seller and
obtained the Seller’s agreement with the text thereof, except as may be required by Law or any
listing agreement with, or the rules of the NYSE, in which case the Purchaser shall use
commercially reasonable efforts to consult with the Seller prior to such release or public
statement.

          Section 7.6 Employee Matters.

               (a) Effective on or prior to the last payroll period prior to the Closing Date, the Seller
shall cause the employment of each individual listed on Section 7.6(a) of the Seller
Disclosure Letter (to the extent still then employed by the Seller or any of its Subsidiaries other
than the Subject Companies) to be transferred to a Subject Company, provided, however, that the
Parties may mutually agree, upon prior written consent, to transfer any other employee to the
Subject Companies from the Seller or from the Subject Companies to the Seller during the period
beginning on the date hereof and ending on the Closing Date (each such individual and each Business
Employee who as of the Closing Date are employed by a Subject Company, collectively, the
“Continuing Employees”). For a period beginning immediately after the Closing Date and
ending on March 31, 2010, and subject to the
remaining paragraphs of this Section 7.6 and the individual’s continued

49

 

employment
with Purchaser or its Affiliates, Purchaser shall cause each Continuing Employee to be provided
with base salary or base wages and target annual cash bonus opportunity no less than the base
salary or base wages and target annual cash bonus opportunity applicable to the Continuing Employee
as of the Closing Date. In addition, for a period beginning immediately after the Closing Date and
ending on December 31, 2009, and subject to the remaining paragraphs of this Section 7.6
and the individual’s continued employment with the Purchaser or its Affiliates, Purchaser shall
cause each Continuing Employee to be provided with other employee benefits (but specifically
excluding defined benefit plan benefits, retiree medical benefits, equity based compensation, or
benefits under the Power of One Incentive Plan (or “Power Bucks” benefits) substantially
similar in the aggregate to those employee benefits currently provided to a Continuing Employee
immediately prior to the Closing.

               (b) Except as specifically set forth in the Transition Services Agreement, on or before the
Closing, the Seller shall take, or shall cause to be taken, all actions necessary to cause the
Continuing Employees to cease to accrue any additional benefits after the Closing Date under all
Seller Affiliate Plans that are not Assumed Benefit Plans.

               (c) As of the Closing Date, (i) Seller’s flexible spending account plan (“Seller’s Flex
Plan”) shall transfer and a plan under Section 125 of the Code established or maintained by
Purchaser or one or more of its Affiliates (“Purchaser’s Flex Plan”) shall accept the
transfer of all of the account balances (whether positive or negative) (the “Transferred
Account Balances”) under Seller’s Flex Plan of the Continuing Employees, (ii) the elections,
contribution levels and coverage levels of the Continuing Employees shall apply under Purchaser’s
Flex Plan in the same manner as under Seller’s Flex Plan; and (iii) the Continuing Employees shall
be reimbursed from Purchasers’ Flex Plan for claims incurred at any time during the plan year of
Seller’s Flex Plan in which the Closing Date occurs and submitted to Purchaser’s Flex Plan from
and after the Closing Date on the same basis and the same terms and conditions as under Seller’s
Flex Plan. As soon as practicable after the Closing Date, and in any event within 10 Business Days
after the amount of the Transferred Account Balances is determined, Seller shall pay Purchaser or
one or more of its Designated Affiliates the net aggregate amount of the Transferred Account
Balances, if such amount is positive, and Purchaser shall, or shall cause one or more of its
Designated Affiliates to, pay Seller the net aggregate amount of the Transferred Account Balances,
if such amount is negative.

               (d) Effective as of the Closing, the Seller shall assign (to the extent they can be assigned)
to the Purchaser, and the Purchaser shall assume, all rights and obligations of the Seller or its
Affiliates under the agreements or arrangements listed on Section 7.6(d) of the Seller
Disclosure Letter.

               (e) The Purchaser shall cause each Continuing Employee and his or her eligible dependents
(including all such Continuing Employee’s dependents covered on the Closing Date by a Seller
Affiliate Plan (other than any Assumed Benefit Plan) that is a group health plan) to be covered
under a group health plan maintained by the Purchaser or an Affiliate of the Purchaser or the
Subject Companies that (i) provides medical and dental benefits to the Continuing Employee and such
eligible dependents effective immediately after the Closing Date and (ii) credits such Continuing
Employee, for the year during which such coverage under such
group health plan begins, with any deductibles and co-payments already incurred during such
year under a Seller Affiliate Plan (other than any Assumed Benefit Plan) that is a group health
plan.

               (f) The Purchaser shall cause the employee benefit plans and programs maintained after the
Closing by the Purchaser and the Affiliates of the Purchaser or to

50

 

which a Continuing Employee may
be eligible to participate in after the Closing Date, to recognize each Continuing Employee’s years
of service and level of seniority as of the Closing Date with the Seller and its Affiliates
(including service and seniority with any other employer that was recognized by the Seller or its
Affiliates) for purposes of terms of employment and eligibility, vesting and, with respect to sick
pay, paid time off, vacation and severance only, benefit determination, under such plans and
programs to the same extent such service was recognized under a similar Seller Affiliate Plan as of
the Closing Date. The Purchaser shall cause each employee welfare benefit plan or program
sponsored by the Purchaser or one of its Affiliates that a Continuing Employee may be eligible to
participate in after the Closing Date to waive any preexisting condition exclusion with respect to
participation and coverage requirements applicable to such Continuing Employee to the same extent
such pre-existing conditions exclusions were not in effect under any Seller Affiliate Plan as of
the Closing Date.

               (g) Provided that on or before the Closing Date the Seller has supplied the Purchaser with a
list of employee layoffs, by date and location, implemented by each of the Subject Companies during
the 90-day period preceding and including the Closing Date, the Purchaser expressly agrees that it
assumes all obligations to provide any required notice under the WARN Act, and to pay all severance
payments, damages for wrongful dismissal and related costs, with respect to the termination of any
Continuing Employee that occurs after the Closing Date. The Seller expressly agrees that it will
retain all obligations to provide any required notice under the WARN Act and to pay all severance
payments, damages for wrongful dismissal and related costs, arising solely as a result of
employment actions of the Subject Companies that occur prior to the Closing Date.

               (h) The Purchaser shall cause each Continuing Employee to be permitted to elect after the
Closing Date (or as soon thereafter as reasonably practicable) a direct rollover of his/her account
balance under a Seller Affiliate Savings Plan (as defined below) to a defined contribution plan
designated by the Purchaser (the “Purchaser Savings Plan”), and the Seller shall cause the
applicable Seller Affiliate Savings Plan to deliver to the Purchaser Savings Plan as soon as
reasonably practicable after such date the promissory notes and other loan documentation, if any,
of each Continuing Employee who has elected such a direct rollover in accordance with the
procedures as determined by the Seller and the Purchaser. The Purchaser and the Seller shall
cooperate and take such reasonable actions, if any, as are necessary to permit the continuation of
loan repayments by Continuing Employees; provided, however, that if a Continuing Employee makes a
direct rollover election as described in this Section 7.6 within such 90 day period, then
the applicable Seller Affiliate Savings Plan shall continue to accept loan repayments from such
Continuing Employee until the date of such direct rollover. The Purchaser shall cause the
Purchaser Savings Plan to accept the direct rollover of electing Continuing Employees’ benefits in
cash and, if applicable, promissory notes that are not accelerated from the Seller Affiliate
Savings Plans. The Seller represents, warrants and agrees with respect to the Seller Affiliate
Savings Plans, and the Purchaser
represents, warrants and agrees with respect to the Purchaser Savings Plan, that, as of each
date of a rollover described in this Section 7.6(h), such plan (i) is intended to satisfy
the requirements of Sections 401(a), (k) and (m) of the Code and (ii) will have received, or the
Purchaser shall cause to be filed within the time period prescribed by the Code an application for
a favorable determination letter from the IRS regarding such qualified status and covering
amendments required to have been adopted prior to the expiration of the applicable remedial
amendment period. Except as required by Law,

51

 

the Purchaser or its designee shall not be required
to provide any particular benefit under the Purchaser Savings Plan. “Seller Affiliate Savings
Plan” means the Reliant Energy, Inc. Savings Plan.

               (i) Claims of Continuing Employees and their eligible beneficiaries and dependents for
medical, dental, prescription drug, life insurance, and/or other welfare benefits (“Welfare
Benefits”) (other than long-term disability benefits) that are incurred on or before the
Closing Date shall be the sole responsibility of the Seller Affiliate Plans. Claims of Continuing
Employees and their eligible beneficiaries and dependents for Welfare Benefits (other than
long-term disability benefits) that are incurred after the Closing Date shall be the sole
responsibility of the Purchaser or its designee. Claims for workers compensation and unemployment
compensation incurred on or prior to Closing shall be the sole responsibility of the Seller and its
Affiliates. For purposes of the preceding provisions of this paragraph, a medical/dental claim
shall be considered incurred on the date when the medical/dental services are rendered or
medical/dental supplies are provided, and not when the condition arose or when the course of
treatment began. Claims for long-term disability benefits that are made under a Seller Affiliate
Plan on or prior to the Closing Date, or claims that are made following the Closing Date that are
associated with a disabling event incurred by a Continuing Employee prior to the Closing Date,
shall be the sole responsibility of the Seller Affiliate Plan. Except as provided in the preceding
sentence, claims of Continuing Employees and their eligible beneficiaries and dependents for
long-term disability and workers’ compensation benefits that are incurred after the Closing Date
shall be the sole responsibility of the Purchaser or its designee. For purposes of the preceding
provisions of this paragraph, claims for long-term disability benefits based on an injury or
illness occurring on or prior to the Closing Date will be deemed to have been incurred prior to the
Closing Date. In the case of any claim for benefits other than a medical/dental claim or a
long-term disability claim, a claim will be deemed to have been incurred upon the occurrence of the
event giving rise to such claim. For avoidance of doubt, Seller and its Affiliates shall retain
all liabilities for providing continuation coverage as required pursuant to COBRA with respect to
any individual and their dependents who were employees of the Subject Companies and whose
qualifying event occurred prior to or on the Closing Date (except to the extent coverage was
provided under an Assumed Benefit Plan, in which case such liability will be borne by Purchaser).

               (j) Except to the extent required by Law, the Seller shall not pay Continuing Employees their
accrued and unused vacation time (as reflected on Subject Company balance sheets or employment
records), and the Purchaser or an Affiliate of the Purchaser, as applicable, shall be required to
provide, without duplication of benefits, all such Continuing Employees all accrued and unused
vacation (to the extent reflected in Subject Company balance sheets or employment records) through
the Closing Date to the extent reflected on the Retail Financial Statements and settled pursuant to
Section 7.13.

               (k) If, within the period of twelve (12) months following the Closing Date, the employment of
a Continuing Employee is terminated by the Purchaser or an Affiliate of the Purchaser or the
Subject Companies for a reason other than cause (as that term is defined in the Severance Plan (as
defined below) as of the date hereof), then, in any such case, the Purchaser shall provide such
Continuing Employee with severance benefits at least equal to the severance benefits which such
Continuing Employee would have received under the Severance

52

 

Plan in which the Continuing Employee
participates as of the date hereof had the employment of such Continuing Employee been terminated
under circumstances entitling him or her to benefits under such plan. Such severance benefits
shall be determined based on the terms of the Severance Plan in effect on the date hereof, but the
Purchaser shall take into account such Continuing Employee’s aggregate service with the Purchaser
and its Affiliates and his or her pre-Closing Date service recognized pursuant to Section
7.6(f). As used in this Agreement, “Severance Plan” shall mean any of the Plans
identified on Section 7.6(k) of the Seller Disclosure Letter.

               (l) Nothing in this Section 7.6 shall represent a guarantee of employment to any of
the Continuing Employees, nor prohibit or restrict in any way the right of the Purchaser or its
Affiliates, as appropriate, to terminate the employment of any Continuing Employee consistent with
applicable Law.

               (m) Prior to or on the Closing Date, Seller shall take all actions necessary to fully vest
each Continuing Employee in their accrued benefit or account balance as of the Closing Date, in any
retirement plan (regardless of whether such retirement plan is intended to qualify under Section
401(a) of the Code) that is a Seller Affiliate Plan other than an Assumed Benefit Plan.

               (n) To the extent reflected on the Retail Financial Statements and settled pursuant to
Section 7.13, the Purchaser shall assume and pay all annual incentive amounts earned or
accrued under the Seller’s incentive and bonus plans set forth on Section 7.6(n) of the
Seller Disclosure Letter (the “Annual Incentive Plans”), and agrees to pay any such amounts
at a time and in a manner that are consistent with the terms of such Annual Incentive Plans and
historical past practices.

               (o) Except as specifically set forth herein, after Closing, the Seller and its Affiliates
(other than the Subject Companies) shall retain and indemnify, defend and hold harmless the
Purchaser, the Subject Companies and its and their Affiliates from and against any liabilities
arising under any Seller Affiliate Plan or any other employee benefit plan program or arrangements
to which the Seller or any ERISA Affiliate of the Seller has any liability, other than an Assumed
Benefit Plan. In addition, the Seller or its Affiliates (other than the Subject Companies) shall
indemnify, defend and hold harmless the Purchaser, the Subject Companies and its and their
Affiliates against any liabilities or obligations of any kind arising prior to the Closing to
provide any post employment health or life insurance benefits to any current or former employees of
the Subject Companies other than as specifically required pursuant to COBRA.

               (p) Prior to the Closing Date, the Seller shall take all actions necessary, if any, to
transfer the sponsorship and liability associated with the Power of One
Incentive Plan to the Seller or one of its Affiliates (other than the Subject Companies) and
shall pay any amounts accrued by any Continuing Employees in accordance with the terms of the Power
of One Incentive Plan as in effect as of the Closing Date. For the avoidance of doubt, neither the
Purchaser nor the Subject Companies shall assume any responsibility or liability with respect to
any benefit under the Power of One Incentive Plan.

53

 

               (q) Nothing contained herein, express or implied: (i) shall be construed to establish, amend,
or modify any benefit plan, program, agreement or arrangement, (ii) shall alter or limit the
Purchaser’s ability to amend, modify or terminate, consistent with this Agreement, any benefit
plan, program, agreement or arrangement at any time assumed, established, sponsored or maintained
by the Purchaser, (iii) is intended to confer upon any current or former employee any right to
employment or continued employment for any period of time by reason of this Agreement, or any right
to a particular term or condition of employment, or (iv) is intended to confer upon any individual
(including employees, retirees, or dependents or beneficiaries of employees or retirees) any right
as a third-party beneficiary of this Agreement.

          Section 7.7 Tax Matters. 

               (a) Transfer Taxes. Notwithstanding any other provision of this Agreement to the
contrary, the Purchaser shall pay all Transfer Taxes, if any, arising out of or in connection with
the transactions contemplated by this Agreement. The Purchaser shall prepare and file all
necessary documentation and Tax Returns with respect to such Transfer Taxes; provided, however,
that the Seller shall cooperate with the Purchaser and take any action reasonably requested by the
Purchaser which does not cause the Seller to incur any cost in order to minimize such Transfer
Taxes. “Transfer Taxes” shall mean any and all transfer Taxes (excluding Taxes measured in
whole or in part by net income or Taxes imposed under Texas Tax Code Section 171), including sales,
use, excise, stock, stamp, documentary, filing, recording, permit, license, authorization and
similar Taxes, fees, duties, levies, customs, tariffs, imposts, assessments, obligations and
charges of the same or of a similar nature to any of the foregoing.

               (b) Tax Returns. Except as otherwise provided in Section 7.7(a) above, the
Seller shall prepare and file or cause to be prepared and filed when due (i) all Tax Returns that
are required to be filed by or with respect to any of the Subject Companies for taxable years or
periods ending on or before the Closing Date and (ii) all Texas franchise Tax Returns in which the
Subject Companies would be included for pre-Closing activities, and the Seller shall remit or cause
to be remitted any Taxes due in respect of such Tax Returns. The Seller shall permit the Purchaser
to review and comment upon such Tax Returns described in clause (ii) of this Section 7.7(b)
prior to the filing thereof, such comments to be considered in good faith by the Seller. The
Purchaser shall prepare and file or cause to be prepared and filed when due all Tax Returns that
are required to be filed by or with respect to any of the Subject Companies for taxable years or
periods ending after the Closing Date (excluding any Texas franchise Tax Returns in which the
Subject Companies would be included for pre-Closing activities), and the Purchaser shall remit or
cause to be remitted any Taxes due in respect of such Tax Returns. All such Tax Returns shall be
prepared in a manner consistent with past practice. The Purchaser shall provide a written request
to the Seller setting forth in detail the computation of the amount owed by the Seller for taxable
periods that end on or before the Closing Date, and,
with respect to any Straddle Period, the portion of such Straddle Period deemed to end on and
include the Closing Date, at least 30 days prior to the due date for the applicable Tax Return.
The Seller shall pay to the Purchaser, no later than two days prior to the due date for the
applicable Tax Return, the Seller’s allocable share pursuant to this Section 7.7 of the
Taxes which are payable with any Tax Return to be filed by the Purchaser with respect to any
Straddle Period. The term “Straddle Period” means a taxable year or period beginning on or
before, and ending after, the Closing Date.

54

 

               (c) Computation of Tax Liabilities. To the extent permitted or required by applicable
Law or administrative practice, the taxable year of each of the Subject Companies which includes
the Closing Date shall be treated as closing on (and including) the Closing Date. For purposes of
apportioning between the Seller and the Purchaser the Taxes of any of the Subject Companies or with
respect to the assets of any of the Subject Companies for a Straddle Period (which is not treated
under the immediately preceding sentence as closing on the Closing Date), such liability shall be
apportioned between the period deemed to end at the close of the Closing Date, and the period
deemed to begin at the beginning of the day following the Closing Date on the basis of an interim
closing of the books, except that Taxes (such as real or personal property Taxes) imposed on a
periodic basis shall be allocated on a daily basis.

               (d) Assistance and Cooperation. Each of the Purchaser and the Seller shall provide the
other with such assistance as may reasonably be requested (including access to the assets,
properties, personnel and records of any of the Subject Companies) by the other Party in connection
with the preparation of any Tax Return, any audit or other examination by any Tax Authority, or any
judicial or administrative proceedings relating to liability for Taxes with respect to any of the
Subject Companies and each shall retain and provide the requesting Party with any records or
information which may be relevant to such return, audit or examination, proceedings or
determination. Any information obtained pursuant to this Section 7.7 or pursuant to any
other Section hereof providing for the sharing of information or review of any Tax Return or other
schedule relating to Taxes with respect to any of the Subject Companies shall be kept confidential
by the Parties hereto except to the extent that a Party is legally compelled to disclose such
information.

               (e) Contests.

               (i) Notice. After the Closing Date, the Purchaser and the Seller shall each
notify the other in writing within ten days of the commencement of any audit or
administrative or judicial proceeding affecting the Taxes or Tax attributes of any of the
Subject Companies, which, if determined adversely to the taxpayer or after the lapse of time
would be grounds for indemnification under this Section 7.7 by the other Party
(“Tax Indemnitor”). Such notice shall contain factual information describing any
asserted Tax liability in reasonable detail and shall include copies of any notice or other
document received from any Tax Authority in respect of any such asserted Tax liability. If
either the Purchaser or the Seller fails to give the other Party prompt notice of an
asserted Tax liability as required under this Agreement, then (A) if the Tax Indemnitor is
precluded by the failure to give prompt notice from contesting the asserted Tax liability in
any administrative or judicial forum, then such Party shall not have any obligation to
indemnify the other Party for any Losses arising
out of such asserted Tax liability and (B) if the Tax Indemnitor is not so precluded
from contesting, if such failure to give prompt notice results in a detriment to the Tax
Indemnitor, then any amount which the Tax Indemnitor is otherwise required to pay pursuant
to this Section 7.7 with respect to such liability shall be reduced by the amount of
such detriment.

               (ii) Control of Contests Involving Pre-Closing Periods or Straddle Periods. In
the case of an audit or administrative or judicial proceeding involving any Taxes or Tax
attributes relating to any taxable years or periods ending on

55

 

or before the Closing Date or
any Straddle Period of any of the Subject Companies, the Seller shall have the right, at its
expense, to control the conduct of such audit or proceeding; provided, however, that if such
audit or proceeding would be reasonably expected to result in a material increase in Tax
liability of any of the Subject Companies for which the Purchaser would be liable under this
Section 7.7, the Purchaser may participate in the conduct of such audit or
proceeding at its own expense and the Seller shall not settle any such audit or proceeding
without the consent of the Purchaser, which consent shall not be unreasonably withheld,
conditioned or delayed.

               (iii) Control of Contests Involving Post-Closing Periods. In the case of an
audit or administrative or judicial proceeding involving any Taxes or Tax attributes
relating to any taxable years or periods beginning on or after the Closing Date of any of
the Subject Companies, the Purchaser shall have the right, at its expense, to control the
conduct of such audit or proceeding; provided, however, that if such audit or proceeding
would be reasonably expected to result in a material increase in Tax liability of any of the
Subject Companies for which the Seller would be liable under this Section 7.7, the
Seller may participate in the conduct of such audit or proceeding at its own expense and the
Purchaser shall not settle any such audit or proceeding without the consent of the Seller,
which consent shall not be unreasonably withheld, conditioned or delayed.

               (f) Indemnification by the Seller. Notwithstanding any other provision of this
Agreement, the Seller shall indemnify the Purchaser and the Subject Companies, as applicable, from
and against and in respect of (i) any and all Losses incurred by the Purchaser or the Subject
Companies, as applicable, which may be imposed on, sustained, incurred, or suffered by or assessed
against the Purchaser or the Subject Companies, as applicable, directly or indirectly, to the
extent relating to or arising out of any liability for Taxes of any of the Subject Companies, for
any taxable year or period that ends on or before the Closing Date and, with respect to any
Straddle Period, the portion of such Straddle Period deemed to end on and include the Closing Date,
(ii) any and all Losses of any person (other than one of the Subject Companies) imposed on one of
the Subject Companies as a transferee or successor, by contract or pursuant to any law, rule or
regulations, which Taxes relate to an event or transaction occurring before the Closing, and (iii)
all Taxes of any member of an affiliated, consolidated, combined or unitary group of which the
Subject Companies is or was a member on or prior to the Closing Date, including pursuant to
Treasury Regulation Section 1.1502-6, Texas Tax Code section 171, or any analogous or similar
state, local, or non-U.S. law or regulation.

               (g) Indemnification by the Purchaser. Notwithstanding any other provision of this
Agreement, the Purchaser shall indemnify the Seller from and against and in respect of any and all
Losses incurred by the Seller, which may be imposed on, sustained, incurred, or suffered by or
assessed against the Seller, directly or indirectly, to the extent relating to or arising out of
(i) any liability for Taxes of any of the Subject Companies for any taxable year or period that
begins after the Closing Date and, with respect to any Straddle Period, the portion of such
Straddle Period beginning the day after the Closing Date or (ii) any liability for Transfer Taxes
arising out of or in connection with the transactions contemplated by this Agreement.

56

 

               (h) Refunds. Any Tax refund (including any interest in respect thereof) received by
the Purchaser or any of the Subject Companies, and any amounts credited against Tax to which the
Purchaser or any of the Subject Companies becomes entitled (including by way of any amended Tax
Returns) that relate to any taxable year or period that ends on or before the Closing Date and,
with respect to any Straddle Period, the portion of such Straddle Period deemed to end on and
include the Closing Date, shall be for the account of the Seller, and the Purchaser shall pay to
the Seller any such refund or the amount of any such credit (net of any Taxes imposed on, and fees
or expenses incurred by, the Purchaser and its Affiliates with respect to such refund or credit)
within fifteen (15) days after receipt or entitlement thereto.

               (i) Tax Sharing Agreements. All Tax allocation, Tax sharing, Tax indemnity or similar
agreements between the Seller or any of its Affiliates (other than any of the Subject Companies),
on the one hand, and any of the Subject Companies, on the other hand, shall be terminated with
respect to any of the Subject Companies on or prior to the Closing Date, and, after the Closing
Date, neither the Seller nor any of its Affiliates (other than any of the Subject Companies), on
the one hand, nor any of the Subject Companies, on the other hand, shall be bound thereby or have
any further liability or obligation thereunder to the other Party.

               (j) Tax Characterization. The Parties agree that, for U.S. federal income Tax
purposes (and, where applicable, state, local, and foreign Tax purposes) the purchase and sale of
the Company Interests constitutes a direct acquisition by the Purchaser from the Seller of all of
the assets of the Company and any entities owned by the Company that are disregarded for U.S.
Federal income tax purposes.

          Section 7.8 Financial Information. 

               (a) After the Closing, upon reasonable written notice, the Purchaser and the Seller shall
furnish or cause to be furnished to each other and their respective accountants, counsel and other
representatives, during normal business hours, such information (including records pertinent to the
Subject Companies) as is reasonably necessary for financial reporting and accounting matters.

               (b) The Purchaser shall retain all of the books and records of the Subject Companies for a
period of six (6) years after the Closing Date or such longer time as may be required by Law.
After the end of such period, before disposing of such books or records, the Purchaser shall give
notice to such effect to the Seller and give the Seller an opportunity to remove and retain all or
any part of such books or records as the Seller may select.

57

 

          Section 7.9 Termination of Affiliate Contracts. Except as set forth in Section 7.9 of the
Seller Disclosure Letter and except as agreed to in writing by the Seller and the Purchaser, all
Affiliate Contracts, including any agreements or understandings (written or oral) with respect
thereto, shall terminate simultaneously with the Closing without any further action or liability on
the part of the parties thereto. Notwithstanding the foregoing, in the absence of a written
agreement, the provision of any services (similar to those contemplated by the preceding sentence)
by the Seller to the Subject Companies from and after the Closing, which services may be provided
by the Seller in its sole discretion, shall be for the convenience, and at the expense, of the
Purchaser.

          Section 7.10 Intentionally Omitted.

          Section 7.11 Seller’s Name. At or prior to the Closing, the Seller shall cause the following
agreements to be terminated: (i) the Amended and Restated Trademark Trust Agreement, dated as of
December 1, 2006 among the Seller, RERH, and Wilmington Trust Company, (ii) the Trademark
Administrative Servicing Agreement between Seller and Trademark Trust, dated December 1, 2006,
(iii) the Trademark License Agreement between Trademark Trust and Seller, dated December 1, 2006,
and (iv) the Trademark License Agreement between Trademark Trust and RERH, dated December 1, 2006.
At the Closing, the Seller shall (and shall cause the Trademark Trust and its trustee and
Affiliates of the Seller to) transfer and deliver to the Purchaser or its designee all of the
right, title and interest in and to the Trademarks pursuant to the Trademark Assignment. Except as
set forth in this Section 7.11, after the Closing, Seller shall, and shall cause each of
its Affiliates (except for the Subject Companies) to, immediately cease the use of, and not use,
apply for, register or maintain, any names, trademarks, service marks or domain names consisting of
or incorporating any of the Trademarks or any names, trademarks, service marks or domain names
confusingly similar thereto, in any fashion. As soon as reasonably practicable after the Closing
but not later than 60 days after the Closing Date, the Seller shall, and shall cause each of its
Affiliates (except for the Subject Companies) to, (i) remove the name “Reliant” (or any variation,
derivation and translations thereof) and all other names incorporating any Trademarks (the
“Reliant Names”) from its email addresses, websites, price lists, invoices, literature,
brochures, manuals, stationery and business cards, and (ii) change its corporate name so that it
does not include any of the Trademarks. As soon as reasonably practicable after the Closing but
not later than 120 days after the Closing Date, the Seller shall, and shall cause each of its
Affiliates (except for the Subject Companies) to, remove the Reliant Names from all other
properties and assets (including facilities, real property signage, signs, flags, supplies and
other materials not set forth in the immediately foregoing sentence). Notwithstanding the
foregoing, immediately after the Closing, the Seller shall not, and shall cause each of its
Affiliates (except for the Subject Companies) not to, use any Reliant Names in any official
correspondence or advertising; provided, however, that, during the period of 120 days after the
Closing Date, the Seller and its Affiliates (except for the Subject Companies) may refer to their
respective corporate names used prior to the Closing immediately following or preceding (as
applicable) the phrase “formerly known as”, “previously doing business as”, “doing business as” or
other equivalent phrases, solely in connection with notifying third parties of the new corporate
names of the Seller or its Affiliates (other than the Subject Companies) or
as required by applicable Law. The Seller shall include in the proxy statement for its 2009
annual meeting of shareholders a proposal to amend the Seller’s Third Restated Certificate of
Incorporation to change the name of the Seller in accordance with this

58

 

Section 7.11 (it being understood and agreed that such proposal may be conditioned upon the Closing occurring).

          Section 7.12 Further Assurances. Each Party will, and will cause its Subsidiaries (or, in the case
of the Purchaser, its Affiliates) to, execute such further documents or instruments and take such
further actions as may reasonably be requested by the other Party in order to consummate the
transactions in accordance with the terms hereof. Each Party to this Agreement shall execute and
deliver such instruments and take such other actions as the other Party may reasonably request in
order to carry out the intent of this Agreement, including, without limitation, (i) the execution
of back-to-back agreements to effect the transfer from the Seller to the Purchaser of the benefits
and burdens to the Seller under any agreement identified in Section 7.12 of the Seller
Disclosure Letter, to the extent that the Seller is unable to transfer or assign such agreement to
the Purchaser or the Purchaser is unable to renegotiate such agreement prior to the Closing Date
and (ii) the delivery of copies of the Source Code to which the Purchaser is provided access, but
not a copy, at Closing. The Parties acknowledge that in connection with the separation of the
Subject Companies from the Seller the Parties may desire to transfer certain assets or contracts
not otherwise provided by this Agreement to the Purchaser or the Subject Companies, or from the
Purchaser or the Subject Companies to the Seller. The Parties agree to reasonably cooperate to
determine what, if any, such assets or contracts (or rights or benefits with respect to such assets
or contracts) should be transferred (or returned to the Seller) to effectuate the general
principles used to divide assets pursuant to this Agreement.

          Section 7.13 Payments in Respect of Closing Working Capital; Accounts Settlement; Excluded
Liabilities Waiver. 

               (a) For purposes of this Agreement, (i) “Designated Current Assets” shall mean all of
the current assets of the Subject Companies reflected in the accounts set forth on Exhibit
O as of the effective time of the Closing as determined in accordance with GAAP consistent with
the accounting principles, practices and methodologies used in the preparation of the December 31,
2008 consolidated balance sheet of the Company, including, but not limited to, the procedures
described in Exhibit O (collectively, the “Settlement Procedures”), (ii)
“Designated Current Liabilities” shall mean (x) all of the current liabilities of the
Subject Companies as of the effective time of the Closing and (y) all escheat deposits of the
Subject Companies as of the effective time of the Closing, in each case reflected in the accounts
set forth on Exhibit O as determined in accordance with the Settlement Procedures and (iii)
“Segregated Cash” shall mean any cash held by any Subject Company as of the effective time
of the Closing that (x) was received by any Subject Company from a customer and (y) under rules
promulgated by the PUCT after the date of this Agreement, is required to be maintained as of the
effective time of the Closing in a segregated account pending application.

               (b) At least three days before the Closing Date, the Seller shall provide the Purchaser with a
good faith estimate of the aggregate amount, if any, by which (x) the amount of accounts payable
included in the Designated Current Liabilities as of the effective
time of the Closing and accounts payable arising from any other accrued Designated Current
Liability as of the effective time of the Closing (collectively, the “Designated Payables”)
(other than Designated Payables that are payable to the Purchaser or any of its Affiliates) which
are due during the 20 days immediately following the Closing Date exceeds (y) the aggregate amount
of

59

 

“Retail Receipts” which are expected to be received during the 20 days immediately following the
Closing Date, based on the daily cash forecast prepared by the Seller’s treasury department in the
ordinary course of business consistent with past practice on the date of such estimate (the
“Estimated Day 20 Deficit”). Within 10 days following the Closing Date the Purchaser shall
provide the Seller with a good faith estimate of the aggregate amount of the Designated Current
Assets minus the aggregate amount of the Designated Current Liabilities of the Subject Companies as
of the effective time of the Closing (the “Adjusted Closing Working Capital”) determined in
accordance with the attached Exhibit N (the “NWC Estimate”) and the Settlement
Procedures using information from the month-end accounting closing. For the avoidance of doubt,
the Adjusted Closing Working Capital shall not include any cash paid to the Seller pursuant to
Section 7.13(c)(i), and the Adjusted Closing Working Capital shall include any cash of the
Subject Companies as of the effective time of the Closing, including any cash contributed by the
Seller to the Subject Companies pursuant to Section 7.13(c)(ii) and including any
Segregated Cash.

               (c) On the Closing Date,

               (i) The Seller shall be entitled to cause the Subject Companies to distribute and pay
to the Seller by wire transfer of immediately available funds an amount not to exceed (A)(1)
the cash and cash equivalents held by the Subject Companies less (2) an amount equal to the
Estimated Day 20 Deficit, plus (B) the amount of Segregated Cash, if any, and

               (ii) if the aggregate amount of any cash and cash equivalents held by the Subject
Companies is less than the Estimated Day 20 Deficit, the Seller shall contribute to the
Company an amount equal to the amount by which the Estimated Day 20 Deficit exceeds such
cash and cash equivalents. The aggregate amount of cash (other than Segregated Cash)
remaining in the Subject Companies as of the effective time of the Closing (after any
distribution pursuant to clause (i) and any contribution contemplated by this clause (ii),
if applicable, is referred to herein as the “Closing Date Cash Funding Amount”.

               (d) After the Closing Date, the Purchaser shall, and shall cause the Subject Companies to,
send invoices in respect of, and use commercially reasonable efforts consistent with the Subject
Companies’ past practices to collect, the accounts receivable included in the Designated Current
Assets as of the effective time of the Closing and the accounts receivable generated in respect of
any unbilled amounts included in the Designated Current Assets as of the effective time of the
Closing (collectively, the “ Designated Accounts Receivable”).

               (e) From and after the Closing, on or before the due date the Purchaser shall review and pay
or dispute, or shall cause the Subject Companies to review and pay or
dispute, consistent with the Subject Companies’ past practices, all Designated Payables and
other Designated Current Liabilities.

               (f) The Purchaser shall not, and shall cause each Subject Company not to, (i) release, waive
or compromise any right in respect of any Designated Account Receivable

60

 

or any other Designated
Current Asset, including any receivable that was written off prior to the effective time of the
Closing, or Designated Current Liability, or (ii) encourage or facilitate any failure or refusal to
pay any Designated Account Receivable or other such current asset.

               (g) The Purchaser shall make, or shall cause the Subject Companies to make, the payments to
the Seller required under Schedule 7.13. All payments pursuant to this Section
7.13(g) shall be made by wire transfer of immediately available funds to an account designated
by the Seller.

               (h) For purposes of determining the amounts payable under this Section 7.13 the
Purchaser shall, and shall cause the Subject Companies to, apply the Settlement Procedures.

               (i) Each Party shall provide the other Party and its representatives with copies of all
applicable records (including supporting documentation generated in connection with any
determination hereunder) necessary for any determination of net working capital or any amounts due
hereunder, as well as access to the employees and representatives of such Party to assist the other
Party in its review of such supporting records and information.

               (j) If the Seller has any objections to any calculation or determination made by the Purchaser
or any Subject Company pursuant to this Section 7.13 (including, for the avoidance of
doubt, Schedule 7.13), the Seller shall notify the Purchaser in writing (the “Notice of
Disagreement”) of such disagreement. The Notice of Disagreement shall set forth in reasonable
detail of the basis for the disagreement. Thereafter, the Seller and the Purchaser shall attempt
in good faith to resolve any such objection. If the Seller and the Purchaser are unable to resolve
in good faith the disagreement within 30 days after the delivery of the Notice of Disagreement,
such disagreement shall be referred to an independent accounting and auditing firm of nationally
recognized standing (who shall not be the regular outside accounting and auditing firm of either
Party) (the “Independent Expert”) mutually selected by the Seller and the Purchaser for a
resolution of such disagreement, in accordance with the requirements of this Section 7.13.
If the Parties do not promptly agree on the selection of an Independent Expert, each of them shall
appoint an independent public accounting firm (the fees, costs and expenses of such independent
public accounting firm shall be borne by the Party appointing such firm) and such two independent
public accounting firms shall jointly select the Independent Expert. Each Party shall submit its
calculation of the disputed components of the relevant item or amount to the Independent Expert,
along with such supporting information as it deems appropriate, on or before the end of the fifth
Business Day following the referral of the matter to the Independent Expert. In making its
determination, the Parties shall jointly instruct the Independent Expert to consider only those
items or amounts as to which the Seller has disagreed, to select which of the two items or amounts
is closer to the appropriate item or amount consistent with the requirements of this Section
7.13, and to notify the Parties as promptly as practicable as to which is so selected. The
Independent Expert’s selection shall be final and binding on the Parties, the
Parties shall use the item or amount selected, and the non-prevailing Party shall bear the
fees and expenses of the Independent Expert. The Parties may agree to any calculation at any time.

               (k) Seller and its Affiliates, in addition to their indemnity obligations in Section
10.2(a)(iii), hereby waive enforcement, release, and fully discharge the Subject

61

 

Companies of
any obligations with respect to the Excluded Liabilities at and as of the effective time of the
Closing.

          Section 7.14 Transition Services Agreement. At or prior to the Closing, the Seller, the IT Trust
and RERH shall enter into the Transition Services Agreement.

          Section 7.15 Computer Systems. 

               (a) At the Closing, the Seller shall and shall cause its Affiliates (excluding the Subject
Companies but including the IT Trust) to:

               (i) transfer to RERH all right, title and interest in and to the computer software (and
accompanying Intellectual Property rights) listed as “Internal” in Section
7.15(a)(i) of the Seller Disclosure Letter;

               (ii) transfer to RERH all right, title and interest in and to any modifications owned
by Seller or any of its Affiliates to the computer software (and accompanying Intellectual
Property rights) listed as “Vendor SW” and in and to any modifications owned by Seller or
any of its Affiliates to any service (and accompanying Intellectual Property rights) listed
as a “service” in Section 7.15(a)(i) of the Seller Disclosure Letter;

               (iii) transfer to RERH the Seller’s entire contractual right to use the computer
software and services listed in Section 7.15(a)(iii) of the Seller Disclosure
Letter, provided that the transfer of applicable Contracts (other than those set forth on
Section 3.2(i) of the Seller Disclosure Letter) shall be subject to obtaining any
applicable Seller Required Consents;

               (iv) transfer to RERH that portion of the Seller’s contractual right to use the
computer software and services listed in Section 7.15(a)(iv) of the Seller

provided that the transfer of applicable Contracts (other than those set forth on
Section 3.2(i) of the Seller Disclosure Letter) shall be subject to obtaining any
applicable Seller Required Consents;

               (v) grant to the Subject Companies a license to computer software listed in Section
7.15(a)(v) of the Seller Disclosure Letter under the terms and conditions of the IP

Seller Disclosure Letter.

               (b) The Parties acknowledge and agree that any third-party consents required in connection
with the assignment or partitioning of any Contracts under Section 7.15(a)(iii) or Section
7.15(a)(iv) shall constitute Seller Required Consents. If obtaining any such Seller Required
Consent or any consent in connection with the satisfaction of the condition

62

 

set forth in
Section 8.2(i) will require the payment of consideration to a third party, each of the
Seller and the Purchaser shall pay fifty percent (50%) of all such consideration. Except as set
forth in the immediately preceding sentence, each of the Seller and the Purchase will be
responsible for on-going costs associated with the assigned or partitioned Contracts of such Party.

          Section 7.16 Insurance. Except as otherwise provided in this Section 7.16, the Purchaser
acknowledges that the Retained Policies will not continue to insure the assets or business of the
Subject Companies after the Closing Date. Except as otherwise provided in this Section
7.16, the Purchaser hereby further acknowledges that after the Closing Date, if a Subject
Company suffers any casualty or loss, including a product liability or workers’ compensation claim,
such loss shall be payable solely by the Purchaser, and shall not be payable by the Seller or under
the Retained Policies. The Seller shall keep in force the Retained Policies for at least six (6)
years after the Closing Date with respect to occurrences on or prior to the Closing Date related to
the Subject Companies or the Retail Business, and shall name the Purchaser and the Subject
Companies as additional named insureds upon the Closing (with the exception of worker’s
compensation insurance, on which Purchaser shall be named as an alternative Employer); provided
that the Seller may, in good faith and consistent with prudent industry practice, discontinue the
Retained Policies after the Closing Date, if the Seller obtains and maintains tail coverage
liability insurance with respect to the Subject Companies and the Retail Business, which shall
remain in effect for at least six (6) years after the Closing Date. The Seller shall provide
notice to its insurer of the Closing of the transactions described in this Agreement. The
Purchaser shall be responsible for any deductibles for claims made after the Closing Date under the
Retained Policies with respect to the Subject Companies and the Retail Business. To the extent the
Purchaser or any of its Affiliates has or obtains substitute policies to the Retained Policies,
such substitute policies shall include a waiver of any rights of subrogation that the insurance
carriers underwriting such policies may have against Seller or Seller’s Affiliates, or under the
Retained Policies.

          Section 7.17 Non-Solicitation. Subject to Section 7.18(g), the Seller agrees that from the
execution of this Agreement to two years after the Closing Date, none of the Seller or any of its
Affiliates will offer (provided that it shall not be deemed an “offer” to conduct a general
solicitation through the use of media advertisements, the internet or professional search firms not
targeted specifically at the Subject Companies (a “General Solicitation”)) to
hire, or otherwise employ any Continuing Employee, other than (i) any individual who initiated
contact with the Seller or any of its Affiliates in response to a General Solicitation, (ii) with
the prior consent of the Purchaser, or (iii) individuals who were terminated by the Purchaser prior
to any discussions of potential employment or terms of employment between any such individual and
the Seller or its Affiliates.

          Section 7.18 Non-Compete.

               (a) The Seller, for itself and on behalf of its wholly owned Subsidiaries (other than the
Subject Companies), agrees that for a period of forty-eight (48) calendar months beginning at the
Closing, neither the Seller nor its wholly owned Subsidiaries (other than the Subject Companies)
shall (i) offer, or participate through ownership, in the sale or marketing of electric energy to
retail customers as a power marketer, Retail Electric Provider, or

63

 

Provider of Last Resort in each
case within the ERCOT region (the “Restricted Business”), or (ii) license any Intellectual
Property owned by the Seller or such Subsidiaries (or use any such Intellectual Property to provide
any services) to any Person that engages in any Restricted Business; provided, however, that
notwithstanding the foregoing, nothing contained herein shall restrict Seller or any of its
Subsidiaries from owning all or any part of, or managing or otherwise participating in any manner
in, any cogeneration project all or a portion of the electric output of which is sold to the steam
host or hosts, or taking any action incidental thereto or holding any license in connection
therewith.

               (b) Effective upon the Closing, Seller shall, or shall cause its wholly owned Subsidiaries
(other than the Subject Companies, REST, or RETR) to, apply for the withdrawal or termination of
any authorizations by any Governmental Authority to supply competitive energy supply services to
retail customers in the ERCOT region; provided, however, that notwithstanding the foregoing,
nothing contained herein shall restrict Seller or any of its Subsidiaries from owning all or any
part of, or managing or otherwise participating in any manner in, any cogeneration project all or a
portion of the electric output of which is sold to the steam host or hosts, or taking any action
incidental thereto or holding any license in connection therewith.

               (c) Nothing contained in this Agreement shall prohibit the Seller or any Subsidiary or
Affiliate of the Seller from entering into an agreement providing for, or from consummating, (i)
any business combination transaction (including any merger, consolidation, stock or asset purchase
or sale or other similar transaction) with, or (ii) any acquisition (whether by merger,
consolidation, stock or asset purchase or other similar transaction) of all or substantially all of
the shares of capital stock of, or all or substantially all of the partnership or other equity
interest in, or all or substantially all of the assets or business of, any Person that engages in
any Restricted Business; provided however, that if (x) such Restricted Business constitutes a
Significant Restricted Business and (y) such transaction does not constitute a Change of Control,
then the Seller shall use commercially reasonable efforts to sell to an unaffiliated third party as
soon as reasonably practicable after such acquisition such Restricted Business, and the conduct of
such Significant Restricted Business pending such sale shall not be prohibited by this Agreement.
In the event that any such Restricted Business does not constitute a Significant Restricted
Business, the conduct of such Restricted Business shall not be prohibited by this Agreement;
further provided that none of the Intellectual Property owned by the Seller
after the Closing, personnel employed by the Seller or any Subsidiary as of the Closing, or
information retained by the Seller concerning the assets, financial condition, results of
operations, customer lists and prospects of the Company and the Retail Business may be utilized in
the conduct of any such Restricted Business (or with respect to such Intellectual Property,
licensed or used to provide any services to any Person (other than the Purchaser or any Subject
Company) that engages in any Restricted Business) for a period of twenty-four (24) months after the
Closing Date (except from and after the occurrence of a Change in Control, in which case the
restrictions of this proviso on the conduct of such Restricted Business shall not apply). For the
avoidance of doubt, nothing contained in this Section 7.18(c) shall be deemed to permit the
Seller or any Subsidiary of the Seller to conduct any Restricted Business using any Reliant Name.

64

 

               (d) Nothing contained in this Agreement shall prohibit the Seller or any Subsidiary or
Affiliate of the Seller from acquiring or holding shares of capital stock or a partnership or other
equity interest in any Person that engages in any Restricted Business if such Restricted Business
constitutes a Significant Restricted Business, where such shares or interest represent no more than
(x) 15% of the outstanding voting power in such Person, if such Person does not have any class of
equity securities registered under the Exchange Act, or (y) 25% of the outstanding voting power in
such Person, if such Person has any class of equity securities registered under the Exchange Act;
provided, however, that in each such case, such shares or interests are purchased and/or held
solely for investment purposes and the Seller and its Affiliates abide by the proviso relating to
the use of Intellectual Property, personnel and information in Section 7.18(c).

               (e) The Seller, for itself and on behalf of its wholly owned Subsidiaries (other than the
Subject Companies), acknowledges and agrees that the restrictions set forth in this Section
7.18 are reasonably designed to protect the Purchaser’s substantial investment and are
reasonable with respect to duration, geographical area and scope and do not impose undue hardship
on the Seller or any of its Subsidiaries. If the final judgment of a court of competent
jurisdiction declares that any term or provision of this Section 7.18 is invalid or
unenforceable, the Parties agree that the court making the determination of invalidity or
enforceability shall have the power to reduce the duration, geographical area or scope of such term
or provision such that the term or provision is valid and enforceable and comes closest to
expressing the intention of the invalid or unenforceable term or provision.

               (f) Certain Definitions. For purposes of this Section 7.18, the following
terms have the following meanings:

               (i) “Change of Control” means any merger, consolidation, restructuring,
transfer of assets or other business combination, sale of shares of capital stock, tender
offer, exchange offer, recapitalization, stock repurchase program or other similar
transaction (x) that results in any Person or Persons beneficially owning 50% or more of any
class of equity securities of the Seller or (y) following which the voting securities of the
Seller outstanding immediately prior to such transaction do not represent (either by
remaining outstanding or by being converted into voting securities of the surviving entity
or any parent thereof) at least 60% of the combined
voting power of the securities of the Seller or such surviving entity or any parent
thereof outstanding immediately after such transaction.

               (ii) “Significant Restricted Business” shall mean, with respect to a particular
Person, the Restricted Business of such Person if more than 20% of such Person’s
consolidated total revenues during the most recently completed fiscal year were derived from
such Person’s Restricted Business.

               (g) Notwithstanding anything in this Agreement to the contrary, none of the restrictions set
forth in Section 7.17 or this Section 7.18 shall apply to (i) for the avoidance of
doubt, any Person that is not directly or indirectly wholly owned by the Seller (other than the
Seller or Persons controlled by the Seller or any of its Subsidiaries), (ii) any Person that, or
any Person who is a Subsidiary or Affiliate of any Person that, (x) acquires all or any portion of
the

65

 

assets of, or equity interests in, the Seller or any of its Subsidiaries (whether by merger,
consolidation, stock or asset purchase or other similar transaction), and (y) prior to such
acquisition was not a wholly owned Subsidiary of the Seller, (iii) any Person that has been a
Subsidiary of the Seller if it ceases to be an Affiliate of the Seller or (iv) the Seller or any of
its Subsidiaries or Affiliates (or any successor or assign of any of the foregoing) from and after
the occurrence of a Change of Control.

          Section 7.19 Transfer of the Seller’s Interest in RESE and Certain Assets Held by RE Supply. The
Seller and the Purchaser agree that on or prior to the Closing Date, the Seller shall (i) transfer
or distribute all of the membership interests in RESE to an Affiliate (other than a Subject
Company) of the Seller (the “RESE Transfer”); (ii) cause RE Supply to assign to Reliant
Energy Services, Inc. or to another Subsidiary of the Seller with market based rates and which is
not a Subject Company, and cause such assignee to assume all of the obligations of RE Supply under,
the contracts set forth in Section 7.19(ii) of the Seller Disclosure Letter (the “RE
Supply Transfer”); (iii) cause the contracts set forth on Section 7.19(iii) of the
Seller Disclosure Letter to be assigned to RESE; and (iv) cause RE Supply to either (x) terminate
and shutdown its membership and settlement account with PJM or (y) transfer to an Affiliate (other
than a Subject Company) of the Seller its membership and settlement account with PJM. Neither the
Seller nor any Subsidiary of the Seller shall have any obligation to pay or otherwise compensate
the Company, RE Supply or the Purchaser for the RESE Transfer or the RE Supply Transfer.

          Section 7.20 Transfer of Certain Assets to the Subject Companies. At or prior to the Closing, the
Seller shall or shall cause the IT Trust and its other Subsidiaries, where applicable, to assign to
the Subject Companies, and shall cause the Subject Companies to assume and agree to perform and
discharge, all contracts listed on Section 3.2(i) of the Seller Disclosure Letter and other
assets listed in Section 7.20 of the Seller Disclosure Letter. On the Closing Date, the
Seller and the Purchaser agree that the Seller shall cause Reliant Energy Services, Inc. to
transfer to the Purchaser, and the Purchaser shall accept and assume and agree to perform, the ICE
cleared swap contracts relating to the Upton Wind Contract held by Reliant Energy Services, Inc. as
of the Business Day prior to the Closing Date
(ICE Deal IDs 6495331, 6495387, 6495558/ Reliant Deal IDs 42286382, 42286383, 42286384). All
such ICE position transfers shall be at the original prices and provisions thereof, for the
remaining term thereof, and each Party shall pay its own broker’s fees and futures clearing member
(FCM) fees.

          Section 7.21 Performance of Obligations under Master Separation Agreement.

               (a) At or prior to the Closing, the Seller shall be entitled to cause each Subject Company to
execute and deliver to the Seller (i) a release by such Subject Company for itself and its
Affiliates (other than Seller and its Subsidiaries (other than the Subject Companies)), successors
and assigns, and all Persons who at any time prior to the “IPO Closing Date” (as defined in the
Master Separation Agreement) have been shareholders, directors, officers, agents or employees of
such Subject Company (in each case, in their respective capacities as such) to effectuate the
provisions of Section 3.1(a) of the Master Separation Agreement, (ii) an agreement not to make any
claim or demand or commence any “Action” (as defined in the Master Separation Agreement,
hereinafter referred to as an “MSA Action”) asserting any claim or demand prohibited by
Section 3.1(d) of the Master Separation Agreement, (iii) an agreement to comply with Section 3.1(e)
of the Master Separation Agreement, (iv) an

66

 

agreement to comply with Article IX of the Master
Separation Agreement (to the extent applicable), (v) an agreement to comply with the provisions of
Section 10.5 of the Master Separation Agreement applicable to a member of the “Resources Group” (as
defined in the Master Separation Agreement), (vi) an agreement to comply with the provisions of
Section 10.9 of the Master Separation Agreement applicable to a member of the “Resources Group” (as
defined in the Master Separation Agreement), (vii) an agreement to comply with the provisions of
Section 10.15 of the Master Separation Agreement and (viii) an agreement that it is bound by the
limitations of liability set forth in Section 11.1 of the Master Separation Agreement to the extent
applicable. The Purchaser shall have the right to review and approve each such document
contemplated herein, such approval not to be unreasonably withheld or delayed. From and after the
Closing, the Purchaser shall cause each Subject Company to comply with and perform its obligations
under the agreements referred to in clauses (ii), (iii), (iv), (v), (vi), and (vii) of this
Section 7.21(a).

               (b) Following the Closing Date, if the Seller receives written notice from any “REI
Indemnitee” (as defined in the Master Separation Agreement) seeking indemnification from any
Subject Company or alleging circumstances that the Seller believes would reasonably be expected to
lead to a claim for indemnification pursuant to Section 3.2 of the Master Separation Agreement, the
Seller shall deliver such written notice to the Purchaser as soon as reasonably practicable. At no
cost to the Purchaser, the Seller shall also provide to the Purchaser, in a timely manner, copies
of all agreements, exhibits, filings or other documentation in Seller’s possession which are
applicable to any such indemnification claim against a Subject Company (except where doing so would
violate any applicable confidentiality restrictions).

               (c) From and after the Closing, when requested by the Purchaser on behalf of any Subject
Company, the Seller shall use commercially reasonable efforts to enforce (i) the releases
contemplated by the Master Separation Agreement and (ii) the covenants and
agreements of the “REI Group” (as defined in the Master Separation Agreement) applicable to
such Subject Company. Enforcement at the request of the Purchaser shall be at cost of the
Purchaser, and unless specified elsewhere in this Agreement, the cost of any joint enforcement
activity shall be shared equally among the Seller and the Purchaser.

               (d) Without limiting the generality of Section 7.21(c), in prosecuting or defending
any claim on behalf of a Subject Company under the Master Separation Agreement, including any claim
for indemnification by or from a Subject Company (each a “Subject Company MSA Claim”), the
Seller shall, at the cost and expense of the Purchaser, (i) diligently, in good faith and on a
commercially reasonable basis, prosecute or defend, as applicable, using counsel selected by the
Purchaser, the Subject Company MSA Claim, and consult in good faith with the Company regarding such
prosecution or defense, (ii) provide the Company with copies of all notices, pleadings, subpoenas,
filings, correspondence or other documents received in connection with the Subject Company MSA
Claim, and (iii) give the Company adequate prior notice of, and the full opportunity to review and
comment on, all filings, motions or other pleadings with respect to the Subject Company MSA Claim.
In addition, the Seller shall not take any action to settle, terminate or cease litigation of any
Subject Company MSA Claim, or to appeal or to decline to appeal any finding, ruling, order or
judgment in connection with such prosecution or defense of such Subject Company MSA Claim, in any
case without the prior

67

 

written consent of the Company. The Seller shall not assert any Subject
Company MSA Claim unless requested to do so by the Purchaser.

               (e) If the Seller learns of any act or omission by any member of the REI Group that the Seller
believes is reasonably likely to constitute a breach of the Master Separation Agreement related to
the Retail Business, the Seller shall provide the Purchaser with notice thereof. If the Seller
receives any written notice from CenterPoint under the Master Services Agreement that the Seller
understands relates to the Retail Business, the Seller shall provide a copy of such notice to the
Purchaser as soon as reasonably practicable.

               (f) In connection with any matter covered by this Section 7.21, each Party shall
provide the other Party at the providing Party’s offices and, except as otherwise provided herein,
at no cost with reasonable access to any of its employees with relevant knowledge and to any
documents in its possession (except where doing so would violate any applicable confidentiality
restrictions).

               (g) The Seller shall indemnify, defend and hold harmless the Subject Companies from and
against any indemnification claim against any Subject Company by any “REI Indemnitee” (as defined
in the Master Separation Agreement) under Section 3.2 of the Master Separation Agreement, other
than any claim with respect to which any Subject Company is an “Appropriate Member of the Resources
Group” (as defined in the Master Separation Agreement). The procedures set forth in Section
10.5 shall apply to any claim for indemnification under this Section 7.21(g). For the
avoidance of doubt, the indemnity contemplated in this Section 7.21(g) shall include
corporate related claims against the Seller (as opposed to retail-related or wholesale-related
claims), even if Seller’s past practice was to allocate as an accounting matter the cost of such
claims to its Subsidiaries.

               (h) In addition, from and after the effective time of the Closing, the Purchaser shall
indemnify, defend and hold harmless each of the “REI Indemnitees” (as defined in the Master
Separation Agreement) from and against any and all “Losses” (as defined in the Master Separation
Agreement) of the REI Indemnitees relating to, arising out of or resulting from (without
duplication) any of the matters set forth in Section 3.2 of the Master Separation Agreement to the
extent that any Subject Company is an “Appropriate Member of the Resources Group” (as defined in
the Master Separation Agreement) with respect to such Loss; provided, however, that the obligations
of the Purchaser under this Section 7.21(h) shall be applicable only to “Losses” (as
defined in the Master Separation Agreement) to the extent arising out of the Retail Business. The
Purchasers obligations under this Section 7.21(h) shall be subject to, and performed in
compliance with, the other applicable provisions of Article III of the Master Separation Agreement
(determined as if the Purchaser were the “Appropriate Member of the Resources Group” for such
purposes).

               (i) Between the date of this Agreement and the Closing, the Seller and the Purchaser shall
jointly use commercially reasonable efforts to negotiate in good faith an agreement with
CenterPoint to novate the provisions of the Master Separation Agreement described in Section
7.21(a) and Section 7.21(h) from the Seller to the Subject Companies (but only the
obligations and agreements under such provisions contemplated by and to the extent of Section
7.21(a)) or, with respect to Section 7.21(h), to the Guarantor, in any such case, with
the

68

 

Seller released from such provisions insofar as such provisions relate to the Subject Companies
and CenterPoint having direct rights against the Subject Companies or, with respect to Section
7.21(h), the Guarantor, in respect of such provisions, and to provide the Subject Companies
with contractual rights directly against CenterPoint with respect to the releases, covenants and
agreements of the “REI Group” contemplated by Section 7.21(c) (a “CNP Novation
Agreement”). In the event that the Seller, the Guarantor, CenterPoint and the Subject
Companies enter into a CNP Novation Agreement, the provisions of Section 7.21(c),
Section 7.21(d) and Section 7.21(e) shall become null and void; provided, however,
that the Seller shall not permit the Subject Companies to enter into a CNP Novation Agreement
without the prior written consent of the Purchaser, such consent not to be unreasonably withheld.

               (j) Notwithstanding anything in this Section 7.21 to the contrary, this Section
7.21 shall not apply to any [*****].

          Section 7.22 REST and RETR.

               (a) Not less than 10 days prior to the Closing Date, the Seller will execute any notices
necessary to designate REST and RETR to a “QSE” identified by the Purchaser that is one of the
Subject Companies or an Affiliate of the Purchaser, such designation to be effective as of the
Closing.

 

			
	***	 	The confidential content of this Exhibit 10.1 has been omitted and filed separately with the
Securities and Exchange Commission. Confidential treatment has been requested with respect to the
omitted portions.

69

 

               (b) The Purchaser shall be responsible for obtaining, at its sole cost and expense, any consents,
authorizations, permits or approvals necessary for the transactions contemplated by this
Section 7.22 and for any other regulatory compliance matters associated therewith, and the
Seller’s obligations under this Section 7.22 are conditioned upon receipt of any such
consents, authorizations, permits or approvals. The Seller shall cooperate with the Purchaser in
the Purchaser’s filing of any required applications for consents, authorizations, permits or
approvals.

               (c) For the avoidance of doubt, REST and RETR are not Subject Companies, and shall not be
deemed to have conducted any Retail Business, for any purposes under this Agreement.

               (d) Prior to the transfer contemplated by Section 7.22(a), the Seller shall be
entitled to remove and retain any cash balance in any bank accounts owned by REST and RETR. The
Seller shall cooperate reasonably with the Purchaser regarding the timing of the removal of such
cash.

               (e) On the Closing Date (or, if acceptable to the PUCT, prior to the Closing Date), the
Purchaser and the Seller shall cause RERS to file with the PUCT for each of REST and RETR an
Amendment Application for Retail Electric Providers, in the form promulgated by the PUCT. Each
such amendment shall be effective on the Closing Date and shall be accompanied by (i) credit
support from the Guarantor or an Affiliate thereof effective the day after the Closing Date which
is in a form acceptable to the PUCT and which is sufficient to terminate the Applicable Guarantee
related to the Amendment, and (ii) a request to terminate the Applicable Guarantee related to the
amendment.

               (f) Notwithstanding anything in this Agreement to the contrary, from and after the Closing,
the Purchaser shall indemnify, defend and hold harmless the Seller Indemnified Parties from and
against any and all Losses actually incurred by any of the Seller Indemnified Parties under any
Applicable Guarantee after the Closing.

          Section 7.23
Merrill Lynch New Agreement.

               (a) The Purchaser (i) shall not, and shall cause its Affiliates not to, permit any
modifications or amendments to the terms and conditions of the ML Arrangement Documents that would
(x) be reasonably likely to materially increase the risk of failure of any condition to closing set
forth therein or would be reasonably likely to materially delay such closing or (y) add any
condition to closing the Commitment Letter, the Merrill Lynch New Agreement or any other ML
Arrangement Document that would be reasonably likely to materially increase the risk of failure of
the Merrill Lynch New Agreement to close or would be reasonably likely to materially delay such
closing, (ii) shall not, and shall cause its Affiliates not to, waive compliance by Merrill Lynch
or any of its Affiliates with any term or provision of the Commitment Letter, the Merrill Lynch New
Agreement or any other ML Arrangement Document which would be reasonably likely to (x) result in
the failure of the Merrill Lynch New Agreement to close or (y) adversely affect the rights of the
Seller, or the obligations of the Purchaser, under this Agreement, and (iii) shall use reasonable
best efforts to cause its conditions

70

 

to closing set forth in the Merrill Lynch New Agreement and the other ML Arrangement Documents
to be satisfied as soon as reasonably practicable.

               (b) The Purchaser shall, and shall cause its Affiliates to, use its commercially reasonable
efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things
necessary, proper or advisable to arrange and consummate the transactions described in the
Commitment Letter and the Merrill Lynch New Agreement, including (x) satisfy on a timely basis all
terms, covenants and conditions set forth in the Commitment Letter and, to the extent necessary for
the closing of the Merrill Lynch New Agreement, in the ML Arrangement Documents; (y) enter into the
Merrill Lynch New Agreement and other applicable definitive agreements with respect thereto on the
terms and conditions contemplated by the ML Arrangement Documents; and (z) consummate the
transaction contemplated by the Merrill Lynch New Agreement at or prior to Closing.

               (c) The Purchaser shall, and shall cause its Affiliates to, keep the Seller informed with
respect to any material adverse change with respect to the transaction contemplated by the
Commitment Letter. Without limiting the foregoing, the Purchaser agrees to notify the Seller
promptly, and in any event within two Business Days, if at any time (i) the Commitment Letter shall
expire or be terminated for any reason, (ii) Merrill Lynch notifies the Purchaser or any of its
Affiliates that Merrill Lynch no longer intends to consummate the transaction contemplated by the
Commitment Letter on the terms set forth therein, or (iii) for any reason the Purchaser no longer
believes in good faith that it will be able to consummate the transaction contemplated by the
Commitment Letter.

ARTICLE VIII

          Section 8.1 Conditions to Each Party’s Obligation to Effect the Closing. The respective
obligations of each Party to effect the Closing shall be subject to the satisfaction on or prior to
the Closing Date of the following conditions, except, to the extent permitted by Law, that such
conditions may be waived in writing pursuant to Section 11.2 by the joint action of the

injunction or other order by any federal or state court preventing consummation of the transactions
contemplated hereby shall have been issued and be continuing in effect, and the transactions
contemplated hereby shall not have been prohibited under any applicable federal or state Law
(collectively, “Restraints”); provided, however, that each of the Parties shall have used
all reasonable efforts to prevent the entry of any such Restraints and to appeal as promptly as
possible any such Restraints that may be entered.

               (b) Statutory Approvals. The Seller Required Statutory Approvals and the Purchaser

material respects its agreements and covenants contained in or contemplated by this Agreement which
are required to be performed by it at or prior to the Closing; provided that for purposes of this

Seller set forth in Section 4.1, Section 4.2 or Section 4.3(a) of this

representations and warranties of the Seller set forth in this Agreement (other than the
representations and warranties of the Seller set forth in Section 4.1, Section 4.2
or Section 4.3(a)) shall be true and correct (without giving effect to any limitation as to
“materiality” or “Material Adverse Effect” set forth therein) both at and as of the date of this
Agreement and at and as of the Closing Date, as if made at and as of such time (except to the
extent expressly made as of an earlier date, in which case as of such date), except, in the case of
clause (ii), where the failure of such representations and warranties to be so true and correct
individually or in the aggregate would not have a Retail Material Adverse Effect.

               (c) Seller Required Consents. The Seller Required Consents set forth in Section
8.2(c) of the Seller Disclosure Letter shall have been obtained.

               (d) Material Adverse Change. Since the date of this Agreement, there has been no

this Section 8.2(d).

               (e) Merrill Lynch New Agreement Closing. The transaction described in the Merrill

ARTICLE IX

TERMINATION

          Section 9.1 Termination. This Agreement may be terminated at any time prior to the Closing Date:

               (a) by mutual written consent of the Seller and the Purchaser;

               (b) by the Purchaser or the Seller, if any state or federal Law is adopted or issued, which
has the effect, as supported by the written opinion of outside counsel for such Party, of
prohibiting the Closing, or by any Party if any court of competent jurisdiction in the United
States or any state shall have issued an order, judgment or decree permanently restraining,
enjoining or otherwise prohibiting the Closing, and such order, judgment or decree shall have
become final and nonappealable;

               (c) by the Purchaser or the Seller, by written notice to the other Party, if the Closing Date
shall not have occurred on or before July 31, 2009 (the “Termination Date”); provided,
however, that the right to terminate the Agreement under this Section 9.1(c) shall not be
available to any Party whose failure to fulfill any obligation under this Agreement shall have
proximately contributed to the failure of the Closing Date to occur on or before such date; and
provided, further, that if on the Termination Date the conditions to the Closing
set forth in Section 8.1(b), Section 8.1(c), Section 8.2(c) and/or
Section 8.3(c) shall not have been fulfilled but all other conditions to the Closing shall
be fulfilled or shall be capable of being fulfilled, then the Termination Date shall be extended
for a 60-day period;

               (d) by the Purchaser, by written notice to the Seller, if there shall have been a material
breach by the Seller of any representation, warranty or covenant contained in this Agreement which
has prevented the satisfaction of any condition to the obligations of the Purchaser at the Closing
and, such breach shall not have been remedied within 30 days after receipt by the Seller of notice
in writing from the Purchaser, specifying the nature of such breach and requesting that it be
remedied or the Purchaser shall not have received adequate assurance of a cure of such breach
within such 30-day period;

               (e) by the Seller, by written notice to the Purchaser, if there shall have been a material
breach by the Purchaser of any representation, warranty or covenant contained in this Agreement
which has prevented the satisfaction of any condition to the obligations of the Seller at the
Closing and such breach shall not have been remedied within 30 days after receipt by the Purchaser
of notice in writing from the Seller, specifying the nature of such breach and requesting that it
be remedied or the Seller shall not have received adequate assurance of a cure of such breach
within such 30 day period; or

               (f) by the Purchaser, by written notice to the Seller, if (i) at any time prior to the Closing
Date, the Purchaser receives a Takeover Proposal, (ii) that Takeover Proposal is conditional on
termination of this Agreement, (iii) the board of directors of the Purchaser has determined in good
faith, after consultation with outside legal counsel, that the
failure to effect termination of this Agreement would be reasonably likely to result in a
breach of

74

 

its fiduciary duties under applicable Law, and (iv) the Purchaser enters into a
definitive agreement with respect to that Takeover Proposal contemporaneously with providing such
written notice to the Seller.

          Section 9.2 Effect of Termination.

               (a) In the event of termination of this Agreement by either the Seller or the Purchaser
pursuant to Section 9.1, there shall be no liability on the part of either the Seller or
the Purchaser or their respective officers or directors hereunder, except (i) that the termination
of this Agreement shall not relieve any Party from liability for any intentional or willful breach
of any representation, warranty, covenant or agreement of such Party contained in this Agreement;
(ii) that Section 1.1 (Defined Terms), Section 1.2 (Interpretation), Section
7.2 (Confidentiality), Section 7.5 (Public Announcements), Section 9.2 (Effect
of Termination), Section 11.1 (Amendment and Modification), Section 11.2
(Extension; Waiver), Section 11.3 (Expenses), Section 11.4 (Notices), Section
11.5 (Entire Agreement), Section 11.6 (Severability), Section 11.7 (Applicable
Law; Jurisdiction), Section 11.8 (Waiver of Jury Trial), Section 11.9 (Specific
Performance), and Section 11.10 (Assignment) shall survive the termination; and (iii) if
the Purchaser terminates this Agreement under Section 9.1(f), the Purchaser shall pay
$45,000,000 to the Seller prior to and as a condition to the effectiveness of such termination (the
“Purchaser Termination Fee”). Payment of the Purchaser Termination Fee, if due pursuant to
Section 9.2(a)(iii), shall be the sole and exclusive remedy of the Seller if the Purchaser
terminates this Agreement under Section 9.1(f), and notwithstanding Section 11.9,
the Parties agree that the Seller shall not be entitled to seek the remedy of specific performance
or other injunctive or equitable relief related to any such termination by the Purchaser.

               (b) In the event that the Purchaser shall fail to pay the Purchaser Termination Fee when due
pursuant to Section 9.2(a)(iii), the Purchaser Termination Fee shall accrue interest for
the period commencing on the date such amount became past due, at a rate equal to the prime rate as
reported in the Wall Street Journal on the date such Purchaser Termination Fee was required to be
paid. In addition, if the Purchaser shall fail to pay the Purchaser Termination Fee when due, the
Purchaser shall also pay to the Seller all of the other Seller’s out-of-pocket costs and expenses
(including reasonable attorneys’ fees) in connection with efforts to collect the Purchaser
Termination Fee. The Parties agree that the agreements contained in this Section 9.2 are
an integral part of this Agreement and the transactions contemplated hereby and that the Purchaser
Termination Fee constitutes liquidated damages and not a penalty.

ARTICLE X

INDEMNIFICATION

          Section 10.1 Survival.

               (a) All of the representations and warranties of the Parties set forth in this Agreement shall
survive the Closing and shall remain in full force and effect until April 30, 2010, other than (i)
the representations and warranties of the Seller set forth in Section 4.1,
Section 4.2, Section 4.3(a), Section 4.15 and Section 4.21,
which shall survive the Closing indefinitely, and the representations and warranties of the
Purchaser set forth in Section 5.7,

75

 

which shall survive the Closing indefinitely, and (ii)
any representations and warranties of the Seller with respect to Taxes or as otherwise set forth in
Section 4.8, which shall survive for the applicable statute of limitations period. No
claim may be made against any Party, and no Party shall have any liability to any Person, hereunder
after the applicable survival period for a representation or warranty specified herein shall have
expired, except that, if written notice of any claim for indemnification under Section
10.2(a)(i) or Section 10.2(b)(i) shall have been given in accordance with Section
11.4 within the applicable survival period, then such survival period shall be extended as it
relates to the matters and Losses specifically identified until such claim has been satisfied or
otherwise resolved as provided in this ARTICLE X.

               (b) All of the covenants of the Parties contained in this Agreement shall survive until fully
performed or fulfilled, unless and to the extent only that non-compliance with such covenants is
waived in writing by the Party entitled to such performance. No claim for a breach of a covenant
set forth in this Agreement that (i) by its nature is required to be performed by or prior to
Closing (the “Pre-Closing Covenants”) may be made or brought by any Party hereto after
April 30, 2010 and (ii) by its nature is required to be performed after Closing (the
“Post-Closing Covenants”) may be made or brought by any Person after twelve (12) months
past the last date on which each such Post-Closing Covenant was required to be performed (in each
case, a “Covenant Survival Period”); provided, however, that any obligation to indemnify
and hold harmless shall not terminate with respect to any Losses to which the Person to be
indemnified shall have given written notice in accordance with Section 11.4 setting forth
the specific claim and the basis therefor to the Indemnifying Party before the termination of the
applicable Covenant Survival Period.

               (c) The indemnification obligations of the Seller set forth in Section 10.2(a)(iii)
and Section 10.2(a)(iv) and the indemnification obligations of the Purchaser set forth in
Section 10.2(b)(iii) or Section 10.2(b)(iv) shall survive the Closing indefinitely.

          Section 10.2 Indemnification.

               (a) Indemnification by the Seller. From and after the Closing and subject to the
provisions of this ARTICLE X (including the limitations set forth in Section 10.3
and Section 10.4), the Seller agrees to indemnify, defend and hold harmless the Purchaser
Indemnified Parties from and against:

               (i) any and all Losses actually incurred by any of the Purchaser Indemnified Parties
that arise out of any inaccuracy or breach as of the date hereof or the Closing Date, unless
an earlier date is specified therein (in which case such representation or warranty need
only be true as of such date), of any representation or warranty of the Seller contained (A)
in this Agreement, or (B) in any certificate delivered by the Seller pursuant to Section
3.2(h) of this Agreement; provided that nothing in such certificate will be deemed to
cure any inaccuracy or breach of any representation or warranty of the Seller contained in
this Agreement;

               (ii) any and all Losses actually incurred by any of the Purchaser Indemnified Parties
that arise out of any breach of any covenant or agreement of the Seller contained in this
Agreement;

76

 

               (iii) any and all Losses actually incurred by any of the Purchaser Indemnified Parties
that arise out of any Excluded Liability; or

               (iv) any [*****].

               (b) Indemnification by the Purchaser. From and after the Closing and subject to the
provisions of this ARTICLE X (including the limitations set forth in Section 10.3
and Section 10.4), the Purchaser agrees to indemnify, defend and hold harmless the Seller
Indemnified Parties from and against:

               (i) any and all Losses actually incurred by any of the Seller Indemnified Parties that
arise out of any inaccuracy or breach as of the date hereof or the Closing Date, unless an
earlier date is specified therein (in which case such representation or warranty need only
be true as of such date), of any representation or warranty of the Purchaser contained in
(A) this Agreement, or (B) in any certificate delivered by the Purchaser pursuant to
Section 3.3(c) of this Agreement; provided that nothing in such certificate will be
deemed to cure any inaccuracy or breach of any representation or warranty of the Purchaser
contained in this Agreement;

               (ii) any and all Losses actually incurred by any of the Seller Indemnified Parties that
arise out of any breach of any covenant or agreement of the Purchaser contained in this
Agreement;

               (iii) any and all Losses actually incurred by any of the Seller Indemnified Parties
that arise out of the Actions set forth on Section 4.7 of the Seller Disclosure
Letter; or

               (iv) any [*****].

77

 

          Section 10.3 Limitations.

               (a) Except in the case of any claim arising from a breach of Section 4.1, Section
4.2, Section 4.3(a), Section 4.15 or Section 4.21 and except for claims
arising under Section 7.6 or Section 7.7, none of the Purchaser Indemnified Parties
shall be entitled to indemnification under Section 10.2(a)(i) or Section
10.2(a)(ii) until the aggregate amount of all the Losses actually suffered by the Purchaser
Indemnified Parties exceeds the Deductible Amount, and then only to the extent such Losses exceed,
in the aggregate, the Deductible Amount. Losses subject to indemnification by the Seller pursuant
to Section 10.2(a)(i) or Section 10.2(a)(ii) (other than in respect of any claim
with respect to Section 4.1, Section 4.2, Section 4.3(a), Section
4.15, Section 4.21, Section 7.6 or Section 7.7) relating to any single
breach or series of related breaches by the Seller shall not constitute Losses, and therefore shall
not be applied toward the Deductible Amount or be indemnifiable hereunder, unless such Losses
relating to any single breach or series of related breaches exceed $100,000.

               (b) The maximum aggregate amount of Losses against which the Purchaser Indemnified Parties
shall be entitled to be indemnified under Section 10.2(a)(i) with respect to all claims
thereunder (other than by reason of or resulting from breaches of any of the representations and
warranties contained in Section 4.1, Section 4.2, Section 4.3(a),
Section 4.15 or Section 4.21) shall be an amount equal to $75,000,000.

               (c) The maximum aggregate amount of Losses against which the Purchaser Indemnified Parties
shall be entitled to be indemnified under Section 10.2(a)(i) with respect to all claims
thereunder including by reason of or resulting from breaches of any of the representations and
warranties contained in Section 4.1, Section 4.2, Section 4.3(a),
Section 4.15 or Section 4.21 shall be an amount equal to the Purchase Price.

               (d) NO PARTY SHALL BE LIABLE UNDER THIS AGREEMENT FOR SPECIAL, PUNITIVE, EXEMPLARY,
INCIDENTAL, CONSEQUENTIAL OR INDIRECT DAMAGES OR LOST PROFITS WHETHER BASED ON CONTRACT, TORT,
STRICT LIABILITY, OTHER LAW OR OTHERWISE AND WHETHER OR NOT FROM ANY OTHER PARTY’S SOLE, JOINT OR
CONCURRENT NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT, EXCEPT SUCH DAMAGES THAT ARE PAYABLE TO A
THIRD PARTY WITH RESPECT TO A THIRD PARTY CLAIM FOR WHICH ANY PERSON IS SEEKING INDEMNIFICATION
HEREUNDER, AND EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW,
ANY RIGHT IT MAY HAVE TO RECEIVE SUCH DAMAGES UNDER THIS AGREEMENT.

          Section 10.4 Mitigation; Subrogation.

               (a) Each Indemnified Party shall use commercially reasonable efforts to mitigate any Loss
suffered, incurred or sustained by it arising out of any matter for which it is entitled to
indemnification herein, upon its having obtained actual knowledge of such matter giving rise to
such Loss. In the event that an Indemnified Party shall fail to make such

78

 

commercially reasonable efforts to mitigate such Loss, then notwithstanding anything else to
the contrary contained herein, the Indemnifying Party shall not be required to indemnify the
Indemnified Party for any Loss that could reasonably be expected to have been avoided had the
Indemnified Party made such efforts.

               (b) Upon making any payment to an Indemnified Party for any indemnification claim pursuant to
this ARTICLE X, the Indemnifying Party shall be subrogated, to the extent of such payment,
to any rights which the Indemnifying Party may have against any other parties with respect to the
subject matter underlying such indemnification claim, and such Indemnified Party shall, to the
extent reasonably requested by the Indemnifying Party, cooperate in the enforcement of such rights
against such third party.

               (c) In calculating the amount of any Loss for which any Indemnifying Party is liable under
this ARTICLE X, there shall be deducted the amount of any insurance recoveries, excluding
any amounts which are in effect self-insured whether through retention amounts or otherwise, the
Indemnified Party in fact receives as a direct consequence of the circumstances to which the Loss
related or from which the Loss resulted or arose. The Indemnified Party agrees to make a claim
against any applicable insurance coverage, including, if applicable, the insurance coverage for the
Company to seek recovery for any Loss, and the Indemnifying Party shall have the right to pursue
such recovery against any such insurance coverage in the name of the insured; provided, however,
that the foregoing shall not materially delay the Indemnified Party’s right to receive
indemnification hereunder.

               (d) Notwithstanding anything in this Agreement to the contrary, in the event that the
existence of an obligation for the payment of money to a third party causes any representation or
warranty of the Seller contained in ARTICLE IV to be untrue or incorrect, then, upon the
Seller’s payment in full and discharge of such obligation, the Seller’s indemnification obligations
in respect of any Losses resulting from, arising out of, based on or relating to any such untrue or
incorrect representation or warranty shall be deemed to have been terminated.

          Section 10.5 Indemnification Process. The Party or other Person making a claim for indemnification
under this ARTICLE X shall be, for the purposes of this Agreement, referred to as the
“Indemnified Party” and the Party against whom such claims are asserted under this
ARTICLE X shall be, for the purposes of this Agreement, referred to as the
“Indemnifying Party”. All claims by any Indemnified Party under this ARTICLE X
shall be asserted and resolved as follows:

               (a) An Indemnified Party shall give the Indemnifying Party notice of any matter that an
Indemnified Party has determined has given or could give rise to a right of indemnification under
this Agreement, within 20 days of such determination, stating the amount of the Loss, if known, and
method of computation thereof, and containing a reference to the provisions of this Agreement in
respect of which such right of indemnification is claimed or arises; provided, however, that the
failure to provide such notice shall not release the Indemnifying Party from any of its obligations
under this ARTICLE X except to the extent that
the Indemnifying Party is materially prejudiced by such failure or as contemplated in
Section 10.1.

79

 

               (b) If an Indemnified Party shall receive notice of any Action, audit, demand or assessment
(each, a “Third Party Claim”) against it or which may give rise to a claim for Loss under
this ARTICLE X, within 20 days of the receipt of such notice, the Indemnified Party shall
give the Indemnifying Party notice of such Third Party Claim; provided, however, that the failure
to provide such notice shall not release the Indemnifying Party from any of its obligations under
this ARTICLE X except to the extent that the Indemnifying Party is materially prejudiced by
such failure. Thereafter, the Indemnified Party shall promptly deliver to the Indemnifying Party,
at the Indemnifying Party’s expense, all witnesses, pertinent records, materials and information,
including all copies of all notices and documents (including court papers) received by the
Indemnified Party relating to the Third Party Claim in the Indemnified Party’s possession or under
the Indemnified Party’s control relating thereto as is reasonably required by the Indemnifying
Party. The Indemnifying Party will have the right to participate in the defense of such Third
Party Claim or, by giving notice to the Indemnified Party, to elect to assume and control the
defense of such Third Party Claim at its expense and through counsel of its choice if it gives
notice of its intention to do so to the Indemnified Party within 30 days of the receipt of notice
from the Indemnified Party of such Third Party Claim, and the Indemnifying Party shall not be
liable for any legal expenses of other counsel or any other expenses subsequently incurred by any
Indemnified Party in connection with the defense thereof; provided, however, that if counsel for
the Indemnified Parties advises that there are issues which raise conflicts of interest between the
Indemnifying Party and the Indemnified Party that would make it inappropriate in the judgment of
such counsel for the same counsel to represent both the Indemnified Party and the Indemnifying
Party, the Indemnified Parties may retain counsel reasonably satisfactory to them after
consultation with the Indemnifying Party, and the Indemnifying Party shall pay the reasonable fees
and expenses of such counsel for the Indemnified Parties. Until the Indemnified Party has received
notice of the Indemnifying Party’s election whether to defend any Third Party Claim, the
Indemnified Party shall take reasonable steps to defend (but may not settle) such Third Party
Claim.

               (c) If the Indemnifying Party exercises the right to undertake any such defense against any
such Third Party Claim as provided above, the Indemnified Party shall cooperate with the
Indemnifying Party in such defense and make available to the Indemnifying Party, at the
Indemnifying Party’s expense, all witnesses, pertinent records, materials and information in the
Indemnified Party’s possession or under the Indemnified Party’s control relating thereto as is
reasonably required by the Indemnifying Party. Similarly, in the event the Indemnified Party is,
directly or indirectly, conducting the defense against any such Third Party Claim, the Indemnifying
Party shall cooperate with the Indemnified Party in such defense and make available to the
Indemnified Party, at the Indemnifying Party’s expense, all such witnesses, records, materials and
information in the Indemnifying Party’s possession or under the Indemnifying Party’s control
relating thereto as is reasonably required by the Indemnified Party. The Indemnifying Party shall
be liable for the reasonable legal fees and expenses of counsel employed by the Indemnified Party
for any period after notice of such claim to the indemnifying Party pursuant to Section
10.5(b) during which the Indemnifying Party has not assumed the defense thereof.

               (d) Without the prior written consent of the Indemnified Party (which consent shall not be
unreasonably withheld), the Indemnifying Party shall not enter into any settlement of any Third
Party Claim that would lead to liability or create any financial or other

80

 

obligation on the part of
the Indemnified Party. Notwithstanding the foregoing, if a firm offer is made to settle a Third
Party Claim and fully release and discharge the Indemnified Party from any liability without
leading to any liability for which the Indemnified Party is not entitled to indemnification
hereunder or the creation of a financial obligation on the part of the Indemnified Party or which
does not create or impose any non-financial obligation on the Indemnified Party, and the
Indemnifying Party desires to accept and agree to such offer, the Indemnifying Party shall give
written notice to the Indemnified Party to that effect. If the Indemnified Party fails to consent
to such firm offer within ten days after its receipt of such notice, the Indemnifying Party shall
be relieved of its obligations to defend such Third Party Claim and the Indemnified Party may
contest or defend such Third Party Claim. In such event, the maximum liability of the Indemnifying
Party as to such Third Party Claim will be the amount of such settlement offer plus reasonable
costs and expenses paid or incurred by the Indemnified Party up to the date of said notice, at all
time subject to the additional limitations on the Indemnifying Party’s liability contained in this
Agreement.

          Section 10.6 Exclusive Remedy. The indemnification provisions of this ARTICLE X shall be
the sole and exclusive remedy of each Party (including the Purchaser Indemnified Parties, and the
Seller Indemnified Parties) after the Closing for any breach of the other Party’s representations,

ARTICLE XI

GENERAL PROVISIONS

          Section 11.1 Amendment and Modification. This Agreement may be amended, modified and supplemented
in any and all respects, but only by a written instrument signed by each of the Parties expressly
stating that such instrument is intended to amend, modify or supplement this Agreement.

          Section 11.2 Extension; Waiver. At any time prior to the Closing Date, a Party may (a) extend the
time for the performance of any of the obligations or other acts of the other Party, (b) waive any
inaccuracies in the representations and warranties contained herein or in any document delivered
pursuant hereto, and (c) waive compliance with any of the agreements or conditions contained
herein, to the extent permitted by Law. Any agreement on the part of a Party to any such extension
or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such
Party. The failure of any Party to assert any of its rights under this Agreement or otherwise
shall not constitute a waiver of such rights.

          Section 11.3 Expenses. Except as otherwise provided in this Agreement, all costs and expenses
incurred in connection with this Agreement and the transactions contemplated hereby shall be paid
by the Party incurring such expenses except that the Purchaser shall solely bear the fee payable in
connection with the filing required by the HSR Act. Notwithstanding the foregoing, in any action
or proceeding brought to enforce any provisions of this Agreement, or where any provision hereof is
validly asserted as a defense, the successful party shall be entitled to recover reasonable
attorneys’ fees and disbursements in addition to its costs and expenses and any other available
remedy provided for herein.

          Section 11.4 Notices. Any notice or other communication required or permitted to be delivered to
any Party under this Agreement shall be in writing and shall be deemed properly delivered, given

of receipt (or the first Business Day following such receipt if the transmission is after 5 p.m.
Central Time on such date or if the date is not a Business Day) of transmission by telecopy or

          Section 11.5 Entire Agreement; No Third Party Beneficiaries. This Agreement and the
Confidentiality Agreement (a) constitute the entire agreement and supersede all prior agreements
and understandings, both written and oral, among the Parties with respect to the subject matter
hereof and thereof and (b) are not intended to confer, and shall not confer, upon any Person other
than the Parties hereto any remedies, claims of liability or reimbursement, causes of action or any
other rights whatsoever; provided, however, that each Subject Company is expressly made a third
party beneficiary of Section 7.7(f), Section 7.21(g) and Section 10.2(a) of
this Agreement; provided, further, however, that such designation as a third party beneficiary
shall not in any way limit the ability of the Parties to waive, amend or terminate this Agreement
or any Section or provision hereof, in each case, without the consent of any Subject Company.

          Section 11.6 Severability. Any term or
provision of this Agreement that is held by a court of competent jurisdiction
or other authority to be invalid, void or unenforceable in any situation in any jurisdiction shall
not affect the validity or enforceability of the remaining terms and provisions hereof or the
validity or enforceability of the offending term or provision in any other situation or in any
other jurisdiction. If the final judgment of a court of competent jurisdiction or other authority
declares that any term or provision hereof is invalid, void or unenforceable, the Parties agree
that the court making such determination shall have the power to reduce the scope, duration, area
or applicability of the term or provision, to delete specific words or phrases, or to replace any
invalid, void or unenforceable term or provision with a term or

83

 

 provision that is valid and
enforceable and that comes closest to expressing the intention of the invalid or unenforceable term
or provision.

          Section 11.7 Applicable Law; Jurisdiction. This Agreement shall be governed by and construed in
accordance with the Laws of the State of New York, without regard to principles of conflict of
laws. The Parties hereby declare that it is their intention that this Agreement shall be regarded
as made under the Laws of the State of New York and that the Laws of said State shall be applied in
interpreting its provisions in all cases where legal interpretation shall be required. Each of the
Parties agrees that any action, suit or proceeding arising out of the transactions contemplated by
this Agreement (a “Proceeding”) shall be commenced and conducted exclusively in the federal
or state courts in the Southern District of the State of New York, and each of the Parties hereby
irrevocably and unconditionally: (i) consents to submit to the exclusive jurisdiction of the
federal and state courts in the Southern District of the State of New York for any Proceeding (and
each Party agrees not to commence any Proceeding, except in such courts); (ii) waives any objection
to the laying of venue of any Proceeding in the federal or state courts in the Southern District of
the State of New York; (iii) waives, and agrees not to plead or to make, any claim that any
Proceeding brought in any federal or state court in the Southern District of the State of New York
has been brought in an improper or otherwise inconvenient forum; and (iv) waives, and agrees not to
plead or to make, any claim that any Proceeding shall be transferred or removed to any other forum.
Each of the Parties hereby irrevocably and unconditionally agrees: (1) to the extent such Party is
not otherwise subject to service of process in the State of New York, to appoint and maintain an
agent in the State of New York as such Party’s agent for acceptance of legal process and (2) that
service of process may also be made on such Party by prepaid certified mail with a proof of mailing
receipt validated by the United States Postal Service constituting evidence of valid service, and
that service made pursuant to clause (1) or (2) above shall have the same legal force and effect as
if served upon such Party personally within the State of New York.

          Section 11.8 Waiver of Jury Trial. EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES ANY AND ALL RIGHT
TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE
TRANSACTIONS CONTEMPLATED HEREBY.

          Section 11.9 Specific Performance. The Parties agree that irreparable damage would occur in the event that any provision of
this Agreement is not performed in accordance with its specific terms or is otherwise breached.
The Parties agree that, except as provided in Section 9.2(a), in the event of any breach by
the other Party of any covenant or obligation contained in this Agreement, the other Party shall be
entitled (in addition to any other remedy that may be available to it, including monetary damages)
to seek (a) a decree or order of specific performance to enforce the observance and performance of
such covenant or obligation and (b) an injunction restraining such breach. The Parties further
agree that no Party to this Agreement shall be required to obtain, furnish or post any bond or
similar instrument in connection with or as a condition to obtaining any remedy referred to in this
Section 11.9 and each Party waives any objection to the imposition of such relief or any
right it may have to require the obtaining, furnishing or posting of any such bond or similar
instrument.

          Section 11.10 Assignment. Neither this Agreement nor any of the rights, interests or obligations
hereunder shall be assigned by any Party hereto (whether by operation of law or otherwise) without
the prior written consent of the other Party; provided, however, that (i) the Seller may transfer
the Company Interests to a wholly owned Subsidiary of the Seller, and (ii) the Purchaser may assign
this Agreement, in whole or in part, to an Affiliate in either case as long as such transferee or
assignee agrees in writing to be bound by the applicable terms of this Agreement and no such
transfer or assignment shall relieve the transferor or assignor from its obligations hereunder;
provided further, however, that the Purchaser may assign, transfer or pledge its rights hereunder
to any Person for financing purposes or in connection with the Merrill Lynch New Agreement.

          Section 11.11 Counterparts; Effect. This Agreement may be executed and delivered (including via
facsimile) in one or more counterparts, each of which shall be deemed to be an original, but all of
which shall constitute one and the same agreement.

          Section 11.12 Bulk Sales Waiver. Notwithstanding any provision in this Agreement to the contrary,
neither the Purchaser nor the Seller will comply with the provisions of the bulk sales Laws or
similar Laws (including those regarding Tax clearance certificates) of any jurisdiction in
connection with the transactions contemplated by this Agreement, and the Purchaser hereby
irrevocably waives compliance by the Seller with the provisions of the bulk sales Laws or similar
Laws of any jurisdiction in connection with the transactions contemplated by this Agreement.
