WHEREAS, Defendants have denied, and continue to deny all allegations of wrongdoing, fault, liability or damage to any of the respective plaintiffs in any of the Actions or the Class (defined below), deny that they engaged in any wrongdoing, deny that they committed any violation of law, deny that the Preliminary Proxy Statement or Definitive Proxy Statement are in any way deficient, deny that they acted improperly in any way, believe that they acted properly at all times, believe the Actions have no merit, and maintain that they have committed no disclosure violations or any other breach of duty whatsoever in connection with the Proposed Transaction or any public disclosures, but wish to settle for the reasons set forth herein;

WHEREAS, Plaintiffs in the Actions brought their claims in good faith and continue to believe that their claims have legal merit, but believe that the Supplemental Disclosures (defined below) satisfy their concerns with respect to the Proposed Transaction;

WHEREAS, the entry by Plaintiffs in the Actions into this Memorandum of Understanding (the “MOU”) is not an admission as to the lack of any merit of any claims asserted in the Actions;

WHEREAS, the parties hereto (the “Parties”) recognize the time and expense that would be incurred by further litigation and the uncertainties inherent in such litigation;

-6-

WHEREAS, the Parties have reached an agreement in principle set forth in this MOU providing for settlement of the Actions on the terms and conditions set forth below, which would include, but not be limited to, a release of all claims which were or could have been asserted in the Actions; and

WHEREAS, Plaintiffs’ Counsel have concluded that the terms contained in this MOU are fair and adequate to Dynegy, its shareholders, and the members of the Class (as defined below), and the Parties believe that it is reasonable to pursue the settlement of the Actions before the Court based upon the procedures and terms outlined herein and the benefits and protections offered hereby, and the Parties wish to document their agreement in this MOU.

NOW THEREFORE, the Parties have reached the following agreement in principle which, when reduced to a settlement agreement (the “Settlement Agreement”), is intended to be a full and final resolution of the Released Claims (defined below) (the “Settlement”). The parties agree to use their best efforts to agree upon and execute the Settlement Agreement no later than 14 days after the date of the signing of this MOU. The Settlement through the Settlement Agreement shall provide for and encompass the following and other customary terms:

Supplemental Disclosures. In consideration for the full settlement and release of all Released Claims (defined below), Dynegy will make supplemental disclosures (the “Supplemental Disclosures”) in a supplement to the Definitive Proxy Statement to be filed with the SEC on Form 8-K and as Definitive Additional Materials on Schedule 14A and will disseminate them to shareholders through the filing of a Form 8-K and Definitive Additional Materials on Schedule 14A with the SEC. Defendants acknowledge that the filing and prosecution of the Delaware Action and the Texas Action, discussions with Plaintiffs’ Counsel, and litigation efforts were the cause of the Supplemental Disclosures. The Supplemental Disclosures shall contain substantially similar information to that reflected in Exhibit A hereto.

Certification of Class. The Settlement Agreement shall provide for the conditional certification in the Texas Action, for settlement purposes only, of a non-opt out class that includes any and all record and beneficial holders of Dynegy common stock, their respective successors in interest, successors, predecessors in interest, predecessors, representatives, trustees, executors, administrators, estates, heirs, assigns or transferees, immediate and remote, and any person or entity acting for or on behalf of, or claiming under, any of them, and each of them, together with their predecessors in interest, predecessors, successors in interest, successors, and assigns, who held any such Dynegy common stock at any time between and including August 13, 2010 and the date of consummation of the Merger, but excluding Defendants and any firm, trust, corporation or other entity controlled by any Defendant (the “Class”).

Representations of the Parties & Counsel. Defendants deny and continue to deny that they have committed or aided or abetted in the commission of any unlawful or wrongful act alleged in any of the Actions, and maintain that they diligently and scrupulously complied with their fiduciary duties (to the extent such duties exist), and are entering into this MOU solely because the proposed settlement will eliminate the burden of litigation. Plaintiffs’ Counsel believe that Plaintiffs’ claims have merit but that Defendants would

-7-

assert legal and factual defenses to Plaintiffs’ claims such that, as a result, the terms of this MOU and the terms of the Settlement are fair, reasonable, adequate, and in the best interest of all members of the Class. Plaintiffs’ Counsel further represent that Plaintiffs have been continuous shareholders of Dynegy throughout the period referenced in paragraph 2 and that they have not assigned, encumbered, or otherwise transferred, in whole or in part, the claims in the Actions. Each of the undersigned attorneys affirms that he or she has been duly empowered and authorized to enter into this MOU and, for the purposes of this MOU, the Plaintiff in the Delaware Action authorizes Interim Class Counsel in the Texas Action to execute this MOU on its behalf.

Stay Pending Court Approval. Pending negotiation, execution and Final Approval of the Settlement Agreement and Settlement by the Court, Plaintiffs agree to stay the proceedings in the Texas Action and the Delaware Action and not to initiate any other proceedings other than those incident to the Settlement itself. The Parties’ respective deadlines to respond to any filed or served pleadings or discovery requests are extended pending completion of the settlement proceedings. As used in this MOU, the term “Final Approval” of the Settlement means that the Court has entered a final order and judgment approving the Settlement, dismissing the Texas Action with prejudice on the merits and with each party to bear its own costs (except those costs set forth in paragraphs 6 and 7 below) and providing for such release language as set forth in paragraph 5 below, and that such final order and judgment is final and no longer subject to further appeal or review by the Texas Supreme Court, whether by affirmance on or exhaustion of any possible appeal or review, lapse of time or otherwise; provided, however, and notwithstanding any provision to the contrary in this MOU, Final Approval shall not include (and the Settlement is expressly not conditioned on) the approval of attorneys’ fees and the reimbursement of expenses to Plaintiffs’ Counsel as provided in paragraph 7 below, and any appeal related thereto. The Parties also agree to use their best efforts to prevent, stay or seek dismissal of or oppose entry of any interim or final relief in favor of any member of the Class in any other litigation against any of the Parties to this MOU that challenges the Settlement, the Proposed Transaction, including any transactions contemplated thereby, or otherwise involves, directly or indirectly, a Released Claim (defined below).

Dismissal With Prejudice, Waiver & General Release. The Settlement Agreement shall provide, among other things:

a) for the full and complete discharge, dismissal with prejudice on the merits, settlement and release of, and a permanent injunction barring, any and all manner of claims, demands, rights, liabilities, losses, obligations, duties, damages, costs, debts, expenses, interest, penalties, sanctions, fees, attorneys’ fees, actions, potential actions, causes of action, suits, agreements, judgments, decrees, matters, issues and controversies of any kind, nature or description whatsoever, whether known or unknown, disclosed or undisclosed, accrued or unaccrued, apparent or not apparent, foreseen or unforeseen, matured or not matured, suspected or unsuspected, liquidated or not liquidated, fixed or contingent, including Unknown Claims (defined below), that Plaintiffs or any or all other members of the Class ever had, now have, or may have, whether direct, derivative, individual, class, representative, legal, equitable or of any other type, or in any other

-8-

capacity, against any of the Released Parties (defined below), whether based on state, local, foreign, federal, statutory, regulatory, common or other law or rule (including, but not limited to, any claims under federal securities laws, Sections 14(a) and 20(a) of the Exchange Act and the rules and regulations promulgated thereunder, or state disclosure law or any claims that could be asserted derivatively on behalf of Dynegy), which, now or hereafter, are based upon, arise out of, relate in any way to, or involve, directly or indirectly, any of the actions, transactions, occurrences, statements, representations, misrepresentations, omissions, allegations, facts, practices, events, claims or any other matters, things or causes whatsoever, or any series thereof, that were, could have been, or in the future can or might be alleged, asserted, set forth, claimed, embraced, involved, or referred to in, or related to, directly or indirectly, any of the Actions or the subject matter of any of the Actions (including the Federal Actions) in any court, tribunal, forum or proceeding, including, without limitation, any and all claims which are based upon, arise out of, relate in any way to, or involve, directly or indirectly, (i) the Proposed Transaction or the issuance of any securities in connection therewith, (ii) any deliberations or negotiations in connection with the Proposed Transaction, including the process of deliberation or negotiation by each of Dynegy, Blackstone, and NRG and any of their respective officers, directors or advisors, (iii) the consideration to be received by Class members in connection with the Proposed Transaction, (iv) the Preliminary Proxy Statement, the Definitive Proxy Statement, or any other disclosures, public filings, periodic reports, press releases, additional soliciting material, investor presentations, proxy statements or other statements issued, made available or filed relating, directly or indirectly, to the Proposed Transaction, including claims under the federal securities laws within the exclusive jurisdiction of the federal courts, Section 14(a) of the Exchange Act and the rules and regulations promulgated thereunder, (v) investments in (including, but not limited to, purchases, sales, exercises of rights with respect to and decisions to hold) securities issued by Dynegy, (vi) the fiduciary obligations of the Released Parties (defined below) in connection with the Proposed Transaction, (vii) the sale of certain Dynegy assets by Blackstone to NRG as contemplated by the Purchase and Sale Agreement dated August 13, 2010, or (viii) any of the allegations in any petition, complaint or amendment(s) thereto filed in any of the Actions (collectively, the “Released Claims”); provided, however, that the Released Claims shall not include the right to enforce this MOU or the Settlement or any claims for statutory appraisal in connection with the Proposed Transaction by Dynegy shareholders who properly perfect such appraisal claims and do not otherwise waive their appraisal rights;

b) whether or not each or all of the following persons or entities were named, served with process or appeared in any of the Actions, that “Released Parties” means (i) Dynegy Inc.; The Blackstone Group, L.P.; Blackstone Capital Partners V L.P.; Denali Parent Inc.; Denali Merger Sub Inc.; Xxxxx X. Xxxxxxx; the Estate of and Personal Representatives of the Estate of Xxxxxx X. Xxxxx, Xx.; Xxxxxx Xxxxxxxx; Xxxxxxxx X. Xxxxxxx; Xxxxx Xxxxxxx; Xxxxxx X. Xxxxxxxx; Xxxxxxx X. Xxxxxxx; Xxxxx X. Xxxxxxxxxx; and NRG Energy, Inc., (ii) any person or entity which is or was related to or affiliated with any or all of them or in which any or all of them has or had a controlling interest, and which is or was involved in the Proposed Transaction; and (iii) the respective past or present family members, spouses, heirs, trusts, trustees, executors, estates, administrators, beneficiaries, distributees, foundations, agents, employees,

-9-

fiduciaries, partners, partnerships, general or limited partners or partnerships, joint ventures, member firms, limited liability companies, corporations, parents, subsidiaries, divisions, affiliates, associated entities, shareholders, principals, officers, managers, directors, managing directors, members, managing members, managing agents, predecessors, predecessors-in-interest, successors, successors-in-interest, assigns, financial or investment advisors, advisors, consultants, investment bankers, entities providing any fairness opinion, underwriters, brokers, dealers, lenders, commercial bankers, attorneys, personal or legal representatives, accountants, insurers, co-insurers, reinsurers, and associates, of each and all of the foregoing;

c) that “Unknown Claims” means any claim that Plaintiffs or any other member of the Class does not know or suspect exists in his, her or its favor at the time of the release of the Released Claims as against the Released Parties, including without limitation those which, if known, might have affected the decision to enter into the Settlement. With respect to any of the Released Claims, the Parties stipulate and agree that upon Final Approval of the Settlement, Plaintiffs shall expressly and each member of the Class shall be deemed to have, and by operation of the final order and judgment by the Court shall have, expressly waived, relinquished and released any and all provisions, rights and benefits conferred by or under Cal. Civ. Code § 1542 or any law of the United States or any state of the United States or territory of the United States, or principle of common law, which governs or limits a person’s release of unknown claims and/or is similar, comparable or equivalent to Cal. Civ. Code § 1542, which provides:

“A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR.”

Plaintiffs acknowledge, and the members of the Class by operation of law shall be deemed to have acknowledged, that they may discover facts in addition to or different from those now known or believed to be true with respect to the Released Claims, but that it is the intention of Plaintiffs, and by operation of law the members of the Class, to completely, fully, finally and forever extinguish any and all Released Claims, known or unknown, suspected or unsuspected, which now exist, or heretofore existed, or may hereafter exist, and without regard to the subsequent discovery of additional or different facts. Plaintiffs acknowledge, and the members of the Class by operation of law shall be deemed to have acknowledged, that the inclusion of “Unknown Claims” in the definition of “Released Claims” was separately bargained for and was a material element of the Settlement and was relied upon by each and all of Defendants in entering into the Settlement Agreement;

d) that Defendants and their respective successors in interest, predecessors, representatives, trustees, executors, administrators, heirs, assigns, or transferees, immediate and remote, and any person or entity acting for or on behalf of or claiming under any of them, and each of them, shall fully, finally and forever release, settle and discharge Plaintiffs and Plaintiffs’ Counsel from any and all claims arising out of or relating to their filing and prosecution and settlement of the Actions (the “Release of Plaintiffs”); provided, however, that the Release of Plaintiffs shall not include Defendants’ rights to enforce the Settlement;

-10-

e) that all the Defendants have vigorously denied, and continue to vigorously deny, any wrongdoing or liability with respect to all claims asserted in the Actions, including that they have committed any violations of law, that they have acted improperly in any way, that they have any liability or owe any damages of any kind to Plaintiffs and/or the Class, and that any additional disclosures (including the additional disclosures made in the Supplemental Disclosures) are required under any applicable rule, regulation, statute, or law, but are entering into this MOU and will execute the Settlement Agreement solely because they consider it desirable that the Actions be settled and dismissed with prejudice in order to, among other things, (i) eliminate the burden, inconvenience, expense, risk and distraction of further litigation, (ii) finally put to rest and terminate all the claims that were or could have been asserted against Defendants in the Actions, and (iii) thereby permit the Proposed Transaction to proceed without risk of injunctive or other relief;

f) that Plaintiffs and their counsel believe that the claims they have asserted have legal merit, although they recognize that there are legal and factual defenses to the claims asserted in the Actions that Defendants have raised and might have raised throughout the pendency of the Actions, and that their claims were brought in good faith, but that they are entering into this MOU and will execute the Settlement Agreement because they believe the Settlement is fair, reasonable, adequate, and in the best interests of Plaintiffs, Dynegy, and the Class;

g) that all Defendants shall have the right to withdraw from the Settlement in the event that any court enjoins or otherwise precludes the Proposed Transaction. In the event that any claim related to the subject matter of any of the Actions, the Proposed Transaction, or the Released Claims is commenced or prosecuted against any of the Released Parties in any court prior to Final Approval of the Settlement, Plaintiffs shall cooperate with Defendants in Defendants’ efforts to secure the dismissal thereof (or a stay thereof in contemplation of dismissal following Final Approval of the Settlement);

h) for entry of a final and binding judgment (the “Judgment”) dismissing the Texas Action with prejudice (whether voluntary or involuntary) and, except as set forth in paragraphs 6 and 7 herein, without costs to any Party;

i) that, within five (5) business days of the entry of the Judgment and (1) the judgment has become final and unappealable, or (2) if the Judgment is appealed, all appeals and any subsequent proceedings on remand have been fully and finally resolved without any material effect on the terms of the Judgment, the Plaintiff in the Delaware Action shall file appropriate papers in the Delaware Action to dismiss the Delaware Action with prejudice (whether voluntary or involuntary), and without costs to any party therein; and

-11-

j) that the Settlement, including the payment of attorneys’ fees awarded by the Court is expressly conditioned upon the Proposed Transaction becoming effective under Delaware law.

Notice. Dynegy shall be responsible for providing notice of the proposed Settlement to the members of the Class and Dynegy or its successor(s) in interest shall pay all reasonable costs and expenses incurred in providing notice of the Settlement to the members of the Class. NRG shall not be responsible for any such costs or expenses.

Fees. Plaintiffs and Plaintiffs’ Counsel in the Texas Action and the Delaware Action intend to petition the Court in the Texas Action for an award of fees and expenses in connection with the litigation of the Texas and Delaware Actions (the “Proposed Fee”). As set forth in this MOU, including Paragraph 1, Defendants will not object to the filing of such a petition; however, as of the signing of this MOU, the Parties have been unable to reach an agreement as to a Proposed Fee amount. The Parties will continue to negotiate, and in the event they are unable to agree to a non-objectionable Proposed Fee amount to include in Plaintiff’s petition, Defendants reserve the right to object to the amount sought in such fee application on any and all applicable grounds. In either case, the petition for the Proposed Fee shall be Plaintiffs’ and/or Plaintiffs’ Counsel’s sole application for an award of fees or expenses in connection with any litigation concerning the Proposed Transaction. Neither Plaintiffs nor Plaintiffs’ Counsel shall make any application for an award of fees or expenses in any other action, including the Delaware Action.

Final resolution by the Court of the Proposed Fee petition shall not be a precondition to the dismissal of the Actions in accordance with the Settlement Agreement, and the Settlement Agreement shall provide that the Fee may be considered separately from the proposed Settlement. The Parties acknowledge and agree that any fees and expenses awarded by the Court in the Texas Action to Plaintiffs’ Counsel shall be paid solely by Dynegy or its successor(s) in interest within ten (10) business days after the later of (a) the entry of an order by the Court approving the Settlement, (b) the entry of an order by the Court awarding attorneys’ fees and expenses, (c) the entry of an order by the Delaware Court dismissing the Delaware Action, or (d) the consummation of the Proposed Transaction, notwithstanding the existence of any timely-filed objections to the Settlement or to the fees and expenses awarded, or potential for appeal from such objections, or collateral attack on the Settlement or any part thereof, subject to the joint and several obligation of Plaintiffs’ Counsel to refund, within ten (10) business days, all amounts received, if and when, as a result of any appeal and/or further proceeding on remand, or successful collateral attack, the fee or expense award is reduced or reversed or if the award order does not become final, if the Settlement itself is voided by any Party as provided herein or in the Settlement Agreement, or if the Settlement is later reversed by any court. NRG shall not be responsible for paying any such award.

Approval. The Settlement Agreement, including the Proposed Fee, is subject to Court approval; provided, however, that the Court’s approval of the Settlement is not contingent on its approval of the Fee. The Parties will attempt in good faith and use their best efforts to negotiate and mutually agree promptly upon the content and form of all documentation as may be required to obtain Final Approval of the Settlement and dismissal of the Actions.

Binding Effect. The Settlement is subject to the following: (a) the drafting and execution of a definitive Settlement Agreement (and such other documentation as may be required to obtain final approval by the Court of the Settlement) by the Parties; (b) Final Approval of the Settlement by the Court; (c) dismissal with prejudice of the Actions as to all members of the Settlement Class (including Plaintiff) and entry by the Court of a final order and judgment containing such release language as is contained in the Settlement Agreement; and (d) the consummation of the Proposed Transaction. This MOU shall be rendered null and void and of no force and effect in the event that the Court fails to grant Final Approval of the Settlement, or the Proposed Transaction, including the Merger, is not consummated for any reason. In any event of nullification of this MOU, the Parties shall be deemed to be in the position they were in prior to the execution of this MOU and the statements made herein and in connection with the negotiation of the MOU or the Settlement shall not be deemed to prejudice in any way the positions of the Parties with respect to any of the Actions, or to constitute an admission of fact of wrongdoing by any Party, shall not be used or entitle any Party to recover any fees, costs or expenses incurred in connection with any of the Actions, and neither the existence of this MOU nor its contents nor any statements made in connection with the negotiation of this MOU or any settlement communications shall be admissible in evidence or shall be referred to for any purpose in any of the Actions, or in any other litigation or judicial proceeding.

The fact of and provisions contained in this MOU, and all negotiations, discussions, actions and proceedings leading up to the execution of this MOU, are confidential and intended for settlement discussions only. If the Settlement does not receive Final Approval, the Parties shall revert to their respective litigation positions as if this MOU never existed.
