F. On or about June 6, 2002, a shareholder derivative suit styled Richard Derusha v. Charles L.

H. The Settling Defendants (as defined below) deny any
wrongdoing, fault, liability or damage to Class Representative or the Class, deny that they engaged in any wrongdoing, deny that they committed any violation of law, and deny that they acted improperly in any way. The Settling Defendants further
believe that (i) they acted properly at all times, and (ii) the Consolidated Securities Litigation, the Federal Derivative Suit and the Texas Derivative Litigation are all without merit.



I. In view of the uncertainty and risk of the outcome of any litigation (especially complex securities litigation), the
difficulties and substantial distractions, burdens, expense and length of time necessary to defend the proceeding, possibly through conclusion of discovery,



4



---

possible summary judgment motions, a possible trial, possible post-trial motions and possible appeals, and to eliminate the distractions, burdens and
expenses of further litigation, the Parties signed the Memorandum of Understanding (as defined below) to settle the Consolidated Securities Litigation and put the Released Claims to rest, finally and forever;



J. This Stipulation shall not be construed or deemed to be a concession by
Class Representative of any infirmity in the claims asserted in the Consolidated Securities Litigation or as a concession by any or all of the Settling Defendants of any wrongdoing, fault, liability or damage to Class Representative, any Class
member, or any other person or entity, or any infirmity in any defense any or all Settling Defendants asserted or could have asserted. The Parties have voluntarily agreed to settle the Consolidated Securities Litigation after consultation with
competent legal counsel;



K. Lead Counsel states that it has
conducted and completed extensive research, discovery and investigation relating to the claims and the underlying events and transactions alleged in the Complaints, including (i) interviews and depositions of current and former Dynegy officers and
employees and other witnesses, (ii) review and analysis of over 1,000,000 pages of documents produced by the Settling Defendants (as defined below) and others, (iii) review and analysis of various public statements and filings made by Dynegy and its
senior officers with the SEC, securities analysts reports, press releases, news articles, and other media reports regarding Dynegy, and (iv) consultation with accounting and damages experts.



L. The Parties, through their respective counsel, have engaged in substantial
arms-length discussions and negotiations to attempt to settle the Consolidated Securities Litigation (including numerous meetings and telephone conferences at which the Settlements terms and conditions were extensively debated and
negotiated) and achieve the best relief possible consistent with the interests of the Class; and



5



---

M. Lead Counsel have carefully researched, considered and evaluated, among other things, the relevant
legal authorities and evidence to support the claims asserted against the Settling Defendants, the likelihood of prevailing on those claims, the attendant risks of further litigation (including likely appeals and subsequent proceedings), the
substantial financial benefits that the Class will receive from the Settlement, the existence and settlement of the Texas Derivative Litigation, and the Insurers (as defined below) contribution of one-hundred fifty million dollars
($150,000,000) toward the Settlement, and have concluded that the Settlement set forth in this Stipulation is fair, reasonable, and adequate to the Class, and in its best interests.



NOW, THEREFORE, without any admission or concession on the part of Class Representative of any lack of merit of the
Consolidated Securities Litigation whatsoever, and without any admission or concession of any liability or wrongdoing or lack of merit in defenses whatsoever by any or all of the Settling Defendants, it is hereby STIPULATED AND AGREED, by and among
the Parties to this Stipulation, through their respective attorneys, subject to Court approval under Federal Rule of Civil Procedure 23(e), in consideration of the benefits flowing to the Parties from the Settlement, that all Released Claims (as

Claims Administrator for alleged damages arising from violations of Section 11 and 15 of the 1933 Act shall be paid from the Insurer Payment.



21



---

14. All claims of the Settlement Class, all fees and expenses of Plaintiffs Counsel, experts,
consultants, and agents, and all administrative or other approval expenses of the Settlement, including Taxes, if any, shall be paid from the Settlement Fund. Settlement Class members shall look solely to the Settlement Fund for settlement and
satisfaction of any and all Released Claims against any and all of the Released Parties. Except as expressly provided in this Stipulation or by Court order, no Settlement Class member shall have any interest in the Settlement Fund or any portion
thereof.



15. The Settlement Fund, net of any Taxes, shall be
used to pay (i) the costs of providing Notice to the Class, (ii) the remaining administrative expenses in connection with the Settlement (including the Claims Administrators costs and expenses), and (iii) the attorneys fees and expenses
award described in paragraph 21. The Net Settlement Fund shall be distributed to the Authorized Claimants as provided in paragraphs 2840. Except as expressly stated in this Stipulation, the Settling Defendants, the Released Parties, and the

expenses awarded by the Court, and amounts due and payable to Settlement Class members. Any sums required to be held hereunder shall be held in escrow by Lead Counsel, as Escrow Agent, shall be deemed to be in the custody, and shall remain subject
to the jurisdiction, of the Court until the funds are distributed pursuant to this Stipulation and/or further Court order.



22

16. The Parties agree that the Settlement Fund is intended to be a Qualified Settlement Fund within the
meaning of Treasury Regulation § 1.468B-1. The Parties further agree to treat the Settlement Fund as coming into existence on the earliest date allowed under Treasury Regulation § 1.468B-1(j)(2). The Escrow Agent, as custodian of the funds
and administrator of the Settlement Fund within the meaning of Treasury Regulation § 1.468B-2(k)(3), shall (i) take all actions necessary for the Settlement Funds treatment as a Qualified Settlement Fund to relate back to the earliest
possible date under Treasury Regulation § 1.468B-1(j)(2)(ii), (ii) file the Settlement Funds tax returns, and (iii) pay from the Settlement Fund any Taxes owed with respect to the Settlement Fund.



17. All Taxes shall be paid out of the Settlement Fund, shall be considered
to be a cost of the Settlements administration and shall be timely paid by the Escrow Agent without prior Court order. None of the Settling Defendants, the Released Parties, or the Insurers shall have any liability with respect to any Taxes,
expenses and/or costs incurred in connection with the taxation of the Settlement Fund or the payment or withholding of Taxes, or the preparation or filing of any returns.



18. The Settlement will be non-recapture, i.e. it is not a claims-made settlement. If all Settlement conditions are
satisfied, the Settling Defendants and Insurers will have no right to a refund of any of the settlement consideration provided in paragraphs 810.



19. Class Representative expressly represents and warrants that, in entering into the Settlement, it relied upon its own knowledge and investigation
(including the knowledge of and investigation performed by Lead Counsel), and not upon any promise, representation, warranty or other statement made by or on behalf of any Settling Defendant not expressly contained in this Stipulation.

CORPORATE GOVERNANCE



20. Within ninety (90) days after the motion for preliminary approval of the Settlement is filed with the Court, Class
Representative will provide a slate of not fewer than five prospective directors to be evaluated by an external search firm of national standing to compare skills, backgrounds and experience with that of Dynegy Inc.s current directors to
confirm fit and complement to Dynegy Inc.s board of directors. By the later of (i) ninety (90) days following the Effective Date, or (ii) ninety (90) days following Class Representatives providing its slate of director candidates to
Dynegy Inc., the Dynegy Inc. Board of Directors will review and confirm the qualifications of said proposed directors. If so confirmed, (a) the Dynegy Inc. Board of Directors will, as promptly as practicable, cause two existing Dynegy Inc. directors
constituting Officer/Director Defendants to resign and will fill such vacancies with two new director nominees selected from the list of five or more proposed by the Class Representative, and (b) Dynegy Inc. management will include in Dynegy
Inc.s proxy statement, as part of managements slate, and will recommend for election to the Dynegy Inc. Board of Directors by its shareholders at its next annual meeting at which directors are elected, the two new director nominees
selected under subparagraph (a) above. If the Dynegy Inc. Board of Directors is unable to confirm the qualifications of two proposed directors from the original slate of five, Class Representative shall provide an additional slate of five
prospective directors. Class Representative shall continue to propose prospective directors in slates of five until such time as the Dynegy Inc. Board has confirmed the qualifications of two such prospective directors and



24



---

named them to the Dynegy Inc. Board of Directors. The qualifications for prospective directors and the specifics of the selection process are set forth in
the Dynegy Inc. Corporate Governance Guidelines, a copy of which is attached as Appendix A.



ATTORNEYS FEES AND EXPENSES



21. Lead Counsel may submit an application or applications (the Fee and Expense Application) for distributions to them from the Settlement Fund for an award of attorneys fees and reimbursement of
expenses incurred in connection with prosecuting the Consolidated Securities Litigation, plus any interest on such attorneys fees and expenses at the same rate and for the same periods as earned by the Settlement Fund (until paid). Lead
Counsel reserve the right to make additional applications for fees and expenses incurred. Class Representative may submit an application for reimbursement of its expenses (including lost wages) incurred in representing the Class in the Consolidated
Securities Litigation.



22. The cash portion, if any, of such
attorneys fees, expenses and interest award shall be paid exclusively from the Settlement Fund to Lead Counsel and/or Class Representative upon award and before the Settlement Funds distribution to Settlement Class members,
notwithstanding the existence of any timely filed objections thereto, or potential for appeal therefrom, or collateral attack on the Settlement or any part thereof. Lead Counsel unconditionally guarantees to refund or repay the Settlement Fund up to
the entire cash amount (if any) of such attorneys fees and expenses award, plus accrued interest at the same net rate earned by the Settlement Fund, within five (5) business days if and when the attorneys fees and expenses award is
reduced or reversed.



25



---

23. Lead Counsel may withdraw from the Settlement Fund the stock, if any, awarded to Lead Counsel as part
of their attorneys fees award, on the later of (i) the date of the stocks deposit into the Settlement Fund or (ii) the date of the Courts decision on the Fee and Expense Application. Any award of stock shall be paid exclusively
from the Settlement Fund upon award and before the Settlement Funds distribution to Settlement Class members, notwithstanding the existence of any timely filed objections thereto, or potential for appeal therefrom, or collateral attack on the
Settlement or any part thereof. If any attorneys fees and expenses award including stock is reduced or reversed, Lead Counsel unconditionally guarantees to return, refund or repay the Settlement Fund up to (i) the total number of such shares
awarded or (ii) if any such awarded shares were sold, the proceeds received from such sale(s).



24. Lead Counsel shall allocate the attorneys fees amongst other Plaintiffs Counsel in a manner in which they in good faith believe reflects the contributions of such counsel to the prosecution and
settlement of the Consolidated Securities Litigation. The Settling Defendants shall have no responsibility for or liability relating to the allocation of attorneys fees and/or the reimbursement of expenses among Plaintiffs Counsel. Any
decision by the Court or any other court concerning the amount of any fee award shall not affect the validity or finality of the Order and Final Judgment. Lead Counsel hereby agrees that it will be subject to the continuing jurisdiction of the Court
in connection with the award of any attorneys fees and/or the reimbursement of expenses.



25. The Courts granting any application by Lead Counsel for attorneys fees and reimbursement of expenses is not a condition of the Settlement. Lead Counsels request for attorneys fees and
reimbursement of expenses is to be considered separately from the Courts



26



---

consideration of whether the Settlement is fair, reasonable, adequate and in the Classs best interests. Any order or proceedings related to any request
for attorneys fees or reimbursement of expenses, or any appeal from any order or proceedings related thereto, shall not affect or delay the Effective Date or the finality of the Order and Final Judgment approving the Settlement.



ADMINISTRATION



26. Lead Counsel may request the Court to appoint a Claims Administrator for
the Settlement. The Settling Defendants, the Released Parties, and the Insurers shall have no responsibility or liability concerning the appointment of the Claims Administrator or any actions taken by the Claims Administrator. The Claims
Administrator shall be responsible for mailing and publishing the Notice and Publication Notice, respectively, and costs for such notice shall be paid from the Settlement Fund. Dynegy shall direct its transfer agent to provide to the Claims
Administrator Dynegys shareholder lists solely for purposes of providing notice to the Class. Class Representative agrees that Dynegys shareholder lists will not be used for any purposes other than providing notice to the Class as
provided in this paragraph and will otherwise not be disclosed to any other persons. All reasonable costs associated with obtaining the shareholder lists shall be paid from the Settlement Fund and Dynegy shall have no liability to the Class with
respect to the provision of such shareholder lists.



27. The
Courts approval of the Plan of Distribution (described in the Notice attached as Exhibit A-1) is not a condition of the Settlement. The Plan of Distribution and determinations made thereunder shall be considered separately from the
Courts consideration of whether the Settlement is fair, reasonable, adequate and in the Classs best interests. Any order or proceedings relating to the Plan of Distribution and determinations thereunder, or any appeal



27



---

from any order or proceedings relating to the Plan of Distribution or any determinations thereunder, shall not affect or delay the Effective Date and the
finality of the Order and Final Judgment.



DISTRIBUTION TO
AUTHORIZED CLAIMANTS



28. The Claims Administrator
shall determine each Authorized Claimants pro rata share of the Net Settlement Fund based upon each Authorized Claimants Claim (as defined in the Plan of Distribution described in the Notice attached as Exhibit A-1, or in such
other Plan of Distribution as the Court approves).



29. The
Plan of Distribution proposed in the Notice is not a necessary term of this Stipulation, and this Stipulation is not conditioned on its approval.



30. Each Authorized Claimant shall be allocated a pro rata share of the Net Settlement Fund based on his or her Claim compared to the total Claims
of all accepted claimants.



31. Any Settlement Class member who
does not submit a valid Proof of Claim will not be entitled to receive any proceeds from the Net Settlement Fund, but will otherwise be bound by all of the terms of this Stipulation, the Settlement, and the Order and Final Judgment, including the
releases and injunctions provided for herein and therein, and will be barred from bringing any action against any or all of the Released Parties concerning any or all of the Released Claims.



28



---

32. Except for the obligation of Dynegy, the Citigroup Entities, and the Insurers to pay into the
Settlement Fund, as described in paragraph 810 above, the Settling Defendants and the Insurers shall have no liability, obligation or responsibility for the administration of the Settlement or disbursement of the Net Settlement Fund. Lead
Counsel shall have the right, but not the obligation, to waive what they deem to be formal or technical defects in any Proof of Claim submitted in the interests of achieving substantial justice.



33. For purposes of determining the extent, if any, to which a Settlement
Class member shall be entitled to be treated as an Authorized Claimant, the following conditions shall apply:



a. Each Settlement Class member shall be required to submit a Proof of Claim (see attached Exhibit A-2), supported by such documents as are designated
therein, including proof of the Claimants loss, or such other documents or proof as Lead Counsel, in its discretion, may deem acceptable;



b. All Proofs of Claim must be submitted by the date specified in the Notice unless such period is extended by Order of the Court. Any Settlement Class
member who fails to submit a Proof of Claim by such date shall be forever barred from receiving any payment pursuant to the Settlement, but shall in all other respects be bound by all of the terms of this Stipulation and the Settlement, including
the terms of the Order and Final Judgment to be entered in the Consolidated Securities Litigation and the releases and injunctions provided for herein and therein, and will be barred from bringing any action against any or all of the Released
Parties concerning any or all of the Released Claims. Notwithstanding the foregoing, Lead Counsel may, in their discretion, accept for processing late-filed claims so long as the distribution of the



29



---

Net Settlement Fund to Authorized Claimants is not materially delayed. A Proof of Claim shall be deemed to have been submitted when posted, if received with
a postmark indicated on the envelope and if mailed by first-class mail and addressed in accordance with the instructions thereon. In all other cases, the Proof of Claim shall be deemed to have been submitted when actually received by the Claims
Administrator;



c. Each Proof of Claim shall be submitted to
and reviewed by the Claims Administrator, who shall determine in accordance with this Stipulation the extent, if any, to which each claim shall be allowed, subject to review by the Court pursuant to subparagraph (e) below;



d. Proofs of Claim that do not meet the submission requirements may be
rejected. Prior to rejection of a Proof of Claim, the Claims Administrator shall communicate with the Claimant in order to remedy the curable deficiencies in the Proof of Claim submitted. The Claims Administrator shall notify, in a timely fashion
and in writing, all Claimants whose Proofs of Claim they propose to reject in whole or in part, setting forth the reasons therefor, and shall indicate in such notice that the Claimant whose claim is to be rejected has the right to a review by the
Court if the Claimant so desires and complies with the requirements of subparagraph (e) below; and



e. If any Claimant whose claim has been rejected in whole or in part desires to contest such rejection, the Claimant must, within twenty (20) calendar
days after the date of mailing of the notice required in subparagraph (d) above, serve upon the Claims Administrator a notice and statement of reasons indicating the Claimants grounds for contesting the rejection along with any supporting
documentation, and requesting a review thereof by the Court. If a dispute concerning a claim cannot be otherwise resolved, Lead Counsel shall thereafter present the request for review to the Court.



30



---

34. Each Claimant shall be deemed to have submitted to the jurisdiction of the Court with respect to the
Claimants claim, and the claim will be subject to investigation and discovery under the Federal Rules of Civil Procedure, provided that such investigation and discovery shall be limited to that Claimants status as a Class member and the
validity and amount of the Claimants claim. No discovery shall be allowed of the Settling Defendants, the Insurers, or the Released Parties or on the merits of the Consolidated Securities Litigation or Settlement in connection with processing
of the Proofs of Claim, and the Settling Defendants shall not be required to provide any information or discovery in connection with processing Proofs of Claim, except as provided herein or ordered by the Court.



35. No person or entity shall have any claim against Class Representative,
Lead Counsel, the Claims Administrator or the Released Parties or their counsel based on the distributions made substantially in accordance with the Stipulation and the Settlement, the Plan of Distribution, or further order(s) of the Court.



36. If there is any balance remaining in the Net Settlement
Fund after six (6) months from the date of distribution of the Net Settlement Fund (whether by reason of tax refunds, uncashed checks or otherwise) Lead Plaintiff either shall reallocate such balance among Authorized Claimants in an equitable and
economic fashion or shall donate it to appropriate 501(c)(3) non-profit organizations.



37. Payment pursuant to this Stipulation shall be deemed final and conclusive against all Settlement Class members. All Settlement Class members whose claims are rejected by the



31



---

Court shall be barred from participating in distributions from the Net Settlement Fund, but otherwise shall be bound by all of the terms of this Stipulation,
the Settlement, and the Order and Final Judgment including the releases and injunctions provided for herein and therein, and will be barred from bringing any action against any or all of the Released Parties concerning any or all of the Released
Claims.



38. All proceedings with respect to the
administration, processing, and determination of claims described by paragraphs 2640 of this Stipulation and the determination of all controversies relating thereto, including disputed questions of law and fact with respect to the validity of
claims, shall be subject to the jurisdiction of the Court.



39.
The Net Settlement Fund shall be distributed to Authorized Claimants by the Claims Administrator only after the Effective Date and after: (i) all Claims have been processed, and all Claimants whose Claims have been rejected or disallowed, in whole
or in part, have been notified and provided the opportunity to be heard concerning such rejection or disallowance; (ii) all objections with respect to all rejected or disallowed claims have been resolved by the Court, and all appeals therefrom have
been resolved or the time therefor has expired; (iii) all matters with respect to attorneys fees, costs, and disbursements have been resolved by the Court and all appeals therefrom have been finally resolved or the time therefor has expired;
and (iv) all costs of administration have been paid.



40. None
of the Settling Defendants or their counsel shall have any responsibility for, interest in, or liability whatsoever with respect to:



a. any act, omission or determination of Lead Counsel, the Escrow Agent or the Claims Administrator, or any of their respective designees
or agents, in connection with the administration of the Settlement or otherwise;



32



---

b. the management, investment, or distribution of the Settlement Fund;



c. the determination, administration, calculation, or
payment of any claims asserted against the Settlement Fund;



d. the Plan of Distribution; or



e. any losses suffered by, or fluctuations in the value of, the Settlement Fund.



TERMS OF PRELIMINARY APPROVAL ORDER



41. Within five (5) business days of this Stipulations execution, the Parties shall jointly apply to the Court for entry of a Preliminary Approval
Order, substantially in the form attached as Exhibit A, and for the scheduling of the Settlement Hearing.

b. the Courts approval of the Settlement, following Notice to the Class and the Settlement Hearing, as prescribed by Federal Rule of Civil Procedure 23;



c. the Courts entry of an Order and Final Judgment, in all material respects in the form set forth in attached Exhibit

subject to review upon appeal or review by writ of certiorari, or, if the Court enters an order and final judgment in form other than that provided above (the Alternative Judgment) and none of the Parties hereto elect to terminate this
Settlement, the date that such Alternative Judgment becomes final and no longer subject to appeal or review; and



d. the settlement of the Texas Derivative Litigation and entry of an order and final, appealable judgment of the 164thDistrict Court for Harris County, Texas, which approves in all respects the dismissal of the claims that have been or could have been asserted in the
Texas Derivative Litigation.



Provided, however, that (i) any award of
attorneys fees or costs, (ii) the approval of any Plan of Distribution, and/or (iii) entry of the Insurer Bar Order shall not be considered a material provision of the Order and Final Judgment and any appeal of any such award, Plan of



34



---

Distribution or decision with respect to the Insurer Bar Order shall not delay the Effective Date and any modification as
a result of such appeal shall not be considered a modification of a material term.



44. Dynegys Counsel or Lead Counsel shall have the right to terminate the Settlement and this Stipulation by providing written notice of such election to the Parties within thirty (30) calendar days of any of
the following events: (i) the Courts declining to enter the Preliminary Approval Order in any material respect; (ii) the Courts declining to approve this Stipulation or any material part of it; (iii) the Courts declining to enter

or reversed in any material respect by any court; or (v) the date on which an Alternative Judgment is modified or reversed in any material respect by any court.



45. Notwithstanding paragraph 44, the following events or occurrences shall not create in Lead Counsel a right to terminate the Settlement: (i) a
decision by the Court to award attorneys fees and expenses in an amount less than the amounts applied for by Lead Counsel; (ii) the approval or denial of any Plan of Distribution; or (iii) entry of the Insurer Bar Order.



46. Class Representative, Dynegy, and the Citigroup Entities, through their
counsel, have executed a Supplemental Agreement setting forth certain conditions under which this Stipulation may be withdrawn or terminated by Dynegy (as to all Parties other than the Citigroup Entities) or by the Citigroup Entities (as
to the Class and the Citigroup Entities only) if potential Class members who purchased in excess of a certain number of Dynegy Class A Common Stock shares during the Class Period exclude themselves from the Class. The Supplemental Agreement



35



---

shall not be filed with the Court unless a dispute arises about its terms or the Court so orders. In the event of a withdrawal from this Stipulation under
the Supplemental Agreement, this Stipulation shall become null and void and of no further force and effect, and the provisions of paragraph 47 shall apply. Notwithstanding the foregoing, the Stipulation shall not become null and void as a result of
Dynegys or the Citigroup Entities election to exercise its option to withdraw from the Stipulation until the conditions in the Supplemental Agreement have been satisfied.



47. Except as otherwise provided herein, if the Settlement is terminated or fails to become effective for any reason, then
(a) the Settlement shall be without force and effect upon the Parties rights, and none of its terms shall be effective or enforceable, except to the extent costs of Notice and administrative expenses or Taxes have been incurred or expended
under this Stipulation; (b) this Stipulation, the fact and terms of the Settlement, and all oral and written communications and other documents pertaining to the Settlement shall be null and void and without prejudice, and shall not be referred to

Settlement Fund, less any costs of Notice or administrative expenses incurred before such termination, and less any Taxes, shall be returned to Dynegy, the Citigroup Entities, and the Insurers on a pro rata basis within five (5) business days; and
(d) the Parties shall revert to their litigation positions as of April 14, 2005.

NO ADMISSION OF WRONGDOING



48. This Stipulation, whether or not consummated, and any act performed or document executed pursuant to or in furtherance
of the Stipulation or the Settlement or any negotiation, discussion or proceedings in connection with this Stipulation or the Settlement:



a. does not constitute and shall not be offered against any or all Released Parties for any reason including, without limitation, as evidence of or
construed as or deemed to be evidence of any presumption, concession, or admission by any or all Released Parties with respect to the truth of any fact alleged by Class Representative or the validity of any claim that had been or could have been
asserted in the Consolidated Securities Litigation or in any litigation, or the deficiency of any defense that has been or could have been asserted in the Consolidated Securities Litigation or in any litigation, or of any liability, negligence,
fault, or wrongdoing of any or all Released Parties;



b. does
not constitute and shall not be offered against any or all Released Parties as evidence of or construed as or deemed evidence of a presumption, concession or admission of any fault, misrepresentation or omission with respect to any statement or
written document approved or made by any or all Released Parties, or against Class Representative and the Class as evidence of any infirmity in the claims of Class Representative and the Class;



c. does not constitute and shall not be offered against any or all Released
Parties as evidence of or construed as or deemed evidence of a presumption, concession or admission with respect to any liability, negligence, fault or wrongdoing, or in any way referred to for any other reason as against any of the Parties to this
Stipulation, in any other civil, criminal or administrative action or proceeding (including, but not limited to, any formal or informal



37



---

investigation or inquiry by the SEC or any other state or federal governmental or regulatory agency), other than such proceedings as may be necessary to
effectuate the provisions of this Stipulation; provided, however, that if this Stipulation is approved by the Court, any or all Released Parties may refer to it to effectuate the liability protection granted them hereunder;



d. does not constitute and shall not be offered or construed against any or
all Released Parties as an admission or concession that the consideration to be given hereunder represents the amount which could be or would have been recovered after trial; and



e. does not constitute and shall not be offered or construed as an admission, concession or presumption against Class
Representative or the Class or any of them that any of their claims are without merit or that damages recoverable under the Complaints would not have exceeded the Settlement Fund. Any or all Released Parties may file the Stipulation and/or the Order
and Final Judgment in any other action or proceeding that may be brought against any or all of them in support of a defense or counterclaim based on principles of res judicata, collateral estoppel, release, good faith settlement, judgment, bar or
reduction, or any theory of claim preclusion or issue preclusion or similar defense or counterclaim. Class Representative understands, acknowledges and agrees that the Released Parties have denied and continue to deny each and all claims of alleged
wrongdoing.



49. The Parties to this Stipulation intend the
Settlement to be a final and complete resolution of all disputes asserted or that could be or could have been asserted by Class Representative, the Class or Plaintiffs Counsel against any or all Settling Defendants and/or Released Parties with
respect to the Released Claims. Accordingly, Class Representative, the Settlement Class, and the Settling Defendants agree not to assert in any forum that the



38

Consolidated Securities Litigation was brought by Class Representative or defended by Defendants in bad faith or without a reasonable basis. The Parties
shall assert no claims of any violation of Rule 11 of the Federal Rules of Civil Procedure relating to the prosecution, defense, or settlement of the Consolidated Securities Litigation. The Parties agree that the amount paid and the other Settlement
terms were negotiated at arms length in good faith by the Parties, and reflect a settlement that was reached voluntarily after consultation with experienced legal counsel.



PUBLIC ANNOUNCEMENTS OF SETTLEMENT



50. Dynegy, Lead Counsel and Class Representative agree to use their best efforts to coordinate, review and provide comments
to all public announcements, by press release or otherwise, regarding the Settlement, but will not have any right to edit, veto or otherwise control the content or form of such communications other than their own.



MISCELLANEOUS PROVISIONS



51. All of the exhibits attached hereto are hereby incorporated by reference
in this Stipulation as though fully set forth herein.



52.
Counsel for each Settling Defendant is authorized to warrant on behalf of such Settling Defendant, and hereby warrants on his, her or its behalf that, as to the payments made by or on behalf of him, her, or it, at the time of such payment that
Settling Defendant made or caused to be made pursuant to paragraphs 8 or 9 above, he, she, or it was not insolvent nor will the payment required to be made by or on behalf of him, her, or it render such Settling Defendant insolvent within the
meaning of and/or for the purposes of the United States Bankruptcy Code, including §§ 101 and 547 thereof. This warranty and all other representations, warranties or statements in this Stipulation, unless expressly indicated otherwise, are
made by the Parties and not by their counsel.

53. If a case is commenced in respect to any Settling Defendant under Title 11 of the United States Code
(Bankruptcy), or a trustee, receiver or conservator is appointed under any similar law, and in the event of the entry of a final order of a court of competent jurisdiction determining the transfer of the Settlement Fund, or any portion thereof, by
or on behalf of such Settling Defendant, to be a preference, voidable transfer, fraudulent transfer or similar transaction, then, as to such Settling Defendant, the releases given and Order and Final Judgment entered in favor of such Settling
Defendant under this Stipulation shall be null and void.



54.
This Stipulation may not be modified or amended, nor may any of its provisions be waived, except by a writing signed by all Parties or their respective successors-in-interest.



55. The headings herein are used for the purpose of convenience only and are not meant and shall not be construed to have
any legal effect.



56. The administration and consummation of
the Settlement embodied in this Stipulation shall be under the Courts authority, and the Court shall retain jurisdiction for the purpose of entering orders providing for awards of attorneys fees and expenses to Lead Counsel and enforcing
the terms of this Stipulation.



57. The waiver by one party of
any breach of this Stipulation by any other party shall not be deemed a waiver of any other prior or subsequent breach of this Stipulation.



58. This Stipulation and its exhibits, together with the Supplemental Agreement, constitute the entire agreement among the Parties concerning the
Settlement of the Consolidated Securities Litigation, and supersede any prior agreements or understandings between the Parties



40



---

with respect to the Settlement (including, without limitation, the Memorandum of Understanding). No representations, warranties, or inducements have been
made by any Party concerning this Stipulation, its exhibits or the Supplemental Agreement, other than those contained and memorialized in such documents.



59. This Stipulation may be executed in one or more counterparts. All executed counterparts and each of them shall be deemed to be one and the same
instrument provided that counsel for the parties to this Stipulation shall exchange among themselves original signed counterparts. Any signature to this Stipulation, to the extent signed and delivered by facsimile, shall be treated in all manners
and respects as an original signature and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. At the request of a Party, any other Party so executing and delivering this
Stipulation by facsimile shall reexecute original forms thereof and deliver them to the requesting party. No Party shall raise the use of facsimile to deliver or transmit a signature as a defense to the formation or enforceability of this
Stipulation, and each such Party forever waives any such defense.



60. This Stipulation shall be binding upon, and inure to the benefit of, the successors and assigns of the Parties and the Released Parties. There are no third-party beneficiaries to this Stipulation.



61. The construction, interpretation, operation, effect and validity of this
Stipulation, and all documents necessary to effectuate it, shall be governed by the internal laws of the State of Texas without regard to conflicts of laws, except to the extent that federal law requires that federal law governs.



41



---

62. This Stipulation shall not be construed more strictly against one Party than another merely by virtue
of the fact that it, or any part of it, may have been prepared by counsel for one of the Parties, it being recognized that it is the result of arms length negotiations between the Parties, and all Parties have contributed substantially and
materially to the preparation of this Stipulation.



63. All
counsel and any other person executing this Stipulation and any of its exhibits, or any related settlement documents, warrant and represent that they have the full authority to do so and that they have the authority to take appropriate action
required or permitted to be taken pursuant to the Stipulation to effectuate its terms.



64. Lead Counsel and the Settling Defendants counsel agree to cooperate fully with one another in seeking prompt Court approval of the Preliminary Approval Order, the Stipulation and the Settlement, and the
entry of the Order and Final Judgment, and to promptly agree upon and execute all such other documentation and to take all such other action as may be reasonably required to obtain the Courts final approval of the Settlement and the entry of
the Order and Final Judgment.



65. All agreements and orders
entered during the course of the Consolidated Securities Litigation relating to the confidentiality of information, including without limitation the Confidentiality Stipulation and Agreed Protective Order filed by the Court on February, 16, 2005,
shall survive this Stipulation and the Settlement.



66. Nothing
in this Stipulation, the Settlement, the negotiations relating thereto, the mediation, or the process and content of confirmatory discovery, is intended to or shall be deemed to constitute a waiver of any applicable privilege or immunity, including,
without limitation, the attorney-client privilege or work product immunity.



42



---

67. The Parties (i) acknowledge their intent to consummate the Settlement and (ii) agree to cooperate as
reasonably necessary to effectuate and implement this Stipulation, and to use their commercially reasonable efforts to accomplish this Stipulations terms and to consummate its contemplated transactions.



68. The Parties acknowledge, represent and warrant to each other that the
mutual releases and payments hereunder are adequate consideration for the consideration given.



69. Lead Counsel shall not assign any of its rights or obligations under this Stipulation (including any rights or obligations as Escrow Agent) without Dynegys prior written consent, and any attempted transfer
or assignment in violation of this provision shall be null and void.
