(i) If at any time there is no currently effective Shelf Registration Statement on file with the Commission, any Holder that holds any Registrable Securities shall have the option and right, exercisable by delivering a written notice to Dynegy (a “Demand Notice,” and the Holder that delivers such a Demand Notice, the “Initiating Holder”), to require Dynegy to, pursuant to the terms of and subject to the limitations contained in this Agreement, prepare and file with the Commission a Registration Statement registering the offering and sale of the number and type of Registrable Securities on the terms and conditions specified in the Demand Notice (or, to the extent permitted under the Commission’s rules and regulations, a prospectus supplement in respect of an existing Registration Statement) in accordance with the intended timing and method or methods of distribution thereof specified in the Demand Notice, which may include sales on a delayed or continuous basis pursuant to Rule 415 (a “Demand Registration”). The Demand Notice must set forth the number of Registrable Securities that the Initiating Holder intends to include in such Demand Registration. Notwithstanding anything to the contrary herein, in no event shall Dynegy be required to effectuate a Demand Registration for Registrable Securities having an aggregate value of less than $25 million based on the VWAP of such Registrable Securities as of the date of the Demand Notice.

(ii) Within ten (10) Business Days of the receipt of the Demand Notice, Dynegy shall give written notice of such Demand Notice to all Holders and, as soon as reasonably practicable thereafter, shall, subject to the limitations of this Section 2(b) and subject to the compliance by the applicable Holders of their obligations under this Agreement, file a Registration Statement (or, to the extent permitted under the Commission’s rules and regulations, a prospectus supplement in respect of an existing Registration Statement) covering all of the Registrable Securities that the Holders shall in writing request (such request to be given to Dynegy within five (5) days of receipt of such notice of the Demand Notice given by Dynegy pursuant to this Section 2(b)(ii)) to be included in such Demand Registration as promptly as reasonably practicable as directed by the Initiating Holder in accordance with the terms and conditions of the Demand Notice and use reasonable best efforts to cause such Registration Statement to become effective under the Securities Act and remain effective under the Securities Act until the earlier of (i) the date that all Registrable Securities covered by such Registration Statement have been sold or (ii) the date that is three (3) years after the original filing date of such Registration Statement (the “Effectiveness Period”).

(iv) Notwithstanding any other provision of this Section 2, Dynegy shall not be required to effect a registration or file a Registration Statement (or any amendment thereto) or maintain the effectiveness of a Registration Statement for a period of up to sixty (60) days, if (A) the Board determines that a postponement is in the best interest of Dynegy and its stockholders relating to a pending transaction involving Dynegy, (B) the Board determines such registration would render Dynegy unable to comply with applicable securities Laws or (C) the Board determines such registration would require disclosure of material information that Dynegy has a bona fide business purpose for preserving as confidential (any such period, a “Blackout Period”); provided, however, that (1) in no event shall any Blackout Period together with any Suspension Period collectively exceed an aggregate of ninety (90) days in any twelve (12) month period, (2) during any Blackout Period contemplated by Section 2(b)(iv)(B) or any Suspension Period, any Holder that has submitted a Demand Notice may withdraw such Demand Notice by written notice to Dynegy, and (3) during any Blackout Period contemplated by Section 2(b)(iv)(B) or any Suspension Period, Dynegy shall not file a registration statement (or any amendment or supplement thereto) with respect to any Dynegy Security for any other holder of registration rights.

(vi) Subject to the limitations contained in this Agreement, Dynegy shall effect any Demand Registration on Form S-3 (except if Dynegy is not then eligible to register for resale the Registrable Securities on Form S-3, in which case such Demand Registration shall be effected on another appropriate form for such purpose pursuant to the Securities Act) and, so long as Dynegy is a WKSI, the Demand Registration for any offering and selling of Registrable Securities shall be effected pursuant to a Shelf Registration Statement, which shall be on Form S-3 or any equivalent or successor form under the Securities Act (if

available to Dynegy); provided, however, that if at any time a Registration Statement on Form S-3 is effective and a Holder provides written notice to Dynegy that it intends to effect an offering of all or part of the Registrable Securities included on such Registration Statement, Dynegy will amend or supplement such Registration Statement as may be necessary in order to enable such offering to take place.

(vii) Without limiting Section 3, in connection with any Demand Registration pursuant to and in accordance with this Section 2(b), Dynegy shall, (A) promptly prepare and file or cause to be prepared and filed (1) such additional forms, amendments, supplements, prospectuses, certificates, letters, opinions and other documents, as may be necessary or advisable to register or qualify the securities subject to such Demand Registration, including under the securities Laws of such states as the Holders shall reasonably request; provided, however, that no such qualification shall be required in any jurisdiction where, as a result thereof, Dynegy would become subject to general service of process or to taxation or qualification to do business in such jurisdiction solely as a result of registration and (2) such forms, amendments, supplements, prospectuses, certificates, letters, opinions and other documents as may be necessary to apply for listing or to list the Registrable Securities subject to such Demand Registration on the Trading Market and (B) do any and all other acts and things that may be reasonably necessary or appropriate or reasonably requested by the Holders to enable the Holders to consummate a public sale of such Registrable Securities in accordance with the intended timing and method or methods of distribution thereof.

(viii) In the event a Holder transfers Registrable Securities to another Holder included on a Registration Statement and such Registrable Securities remain Registrable Securities following such transfer, at the reasonable request of such Holder, Dynegy shall amend or supplement such Registration Statement as may be necessary in order to enable such transferee to offer and sell such Registrable Securities pursuant to such Registration Statement; provided that in no event shall Dynegy be required to file a post-effective amendment to the Registration Statement unless (A) such Registration Statement includes only Registrable Securities held by such Holder or another Holder or (B) Dynegy has received written consent therefor from whom Registrable Securities have been registered on (but not yet sold under) such Registration Statement, other than such Holder or another Holder.

(i) If Dynegy shall at any time propose to conduct, other than pursuant to any Demand Registration, a public offering of Common Stock for cash (whether in connection with a public offering of Common Stock by Dynegy, a public offering of Common Stock by stockholders, or both, but excluding an offering relating solely to an employee benefit plan, an offering relating to a transaction on Form S-4 or S-8 or an offering on any registration statement form that does not permit secondary sales), Dynegy shall promptly notify all Holders of such proposal reasonably in advance of (and in any event at least two (2) Business Days prior for a block trade and five (5) Business Days prior for any other public offering) the commencement of the offering (the “Piggyback Notice”). The Piggyback Notice shall offer the Holders the opportunity to include for registration in such Registration Statement the number of Registrable Securities as they may request (a “Piggyback Registration”). Dynegy shall use reasonable best efforts to include in each such Piggyback Registration such Registrable Securities for which

Dynegy has received a written request from a Holder within three (3) Business Days (or one (1) Business Day for a block trade) after delivery of the Piggyback Notice to such Holder (“Piggyback Request”) for inclusion therein. If a Holder decides not to include all of its Registrable Securities in any Registration Statement thereafter filed by Dynegy, such Holder shall nevertheless continue to have the right to include any Registrable Securities in any subsequent registration statement or registration statements as may be filed by Dynegy with respect to offerings of Common Stock, all upon the terms and conditions set forth herein.

(ii) If the Registration Statement under which Dynegy gives notice under this Section 2(c) is for an underwritten offering, Dynegy shall so advise the Holders of Registrable Securities. In such event, the right of any such Holder to be included in a registration pursuant to this Section 2(c) shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by Dynegy. If the managing underwriter or managing underwriters of such offering advise Dynegy and the Holders in writing that in their reasonable opinion the inclusion of all of the Holders’ Registrable Securities in the subject Registration Statement (or any other Common Stock proposed to be included in such offering) would likely have an adverse effect in any material respect on the price, timing or distribution of Common Stock proposed to be included in such offering, Dynegy shall include in such offering only that number of shares of Common Stock proposed to be included in such offering that, in the reasonable opinion of the managing underwriter or managing underwriters, will not have such effect, with such number to be allocated as follows: (A) first, to Dynegy and/or any holder exercising demand registration rights pursuant to which the offering is being proposed, (B) if there remains availability for additional shares of Common Stock to be included in such registration, second pro rata among all Holders desiring to register Registrable Securities and other holders of Common Stock exercising piggyback rights under other registration rights agreements with Dynegy, based on the number of Registrable Securities held by all such Holders and other holders of Common Stock, and (C) if there remains availability for additional shares of Common Stock to be included in such registration, third pro rata among all other holders of Common Stock who may be seeking to register such Common Stock based on the number of shares of Common Stock such holder is entitled to include in such registration. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice to Dynegy and the managing underwriter(s) delivered on or prior to the time of the commencement of such offering. Any Registrable Securities withdrawn from such underwriting shall be excluded and withdrawn from the registration.

(iii) Dynegy shall have the right to terminate or withdraw any registration initiated by it under this Section 2(c) at any time in its sole discretion whether or not any Holder has elected to include Registrable Securities in such Registration Statement. The registration expenses of such withdrawn registration shall be borne by Dynegy in accordance with Section 4.

(iv) The rights of the Holders under this Section 2(c) shall terminate if the number of Registrable Securities outstanding is less than 5% of the number of outstanding shares of Common Stock.

3. Registration Procedures. The procedures to be followed by Dynegy and each Holder electing to sell Registrable Securities in a Registration Statement (for the avoidance of doubt, including in a Shelf Registration Statement) pursuant to this Agreement, and the respective rights and obligations of Dynegy and such Holders, with respect to the preparation, filing and effectiveness of such Registration Statement, are as follows:

(a) In connection with a Demand Registration or a Shelf Registration, Dynegy will, to the extent reasonably practicable, at least five (5) Business Days prior to the anticipated filing of the Registration Statement and any related Prospectus or any amendment or supplement thereto (other than any filing made under the Exchange Act that is incorporated by reference into the Registration Statement), (i) furnish to such Holders a copy of all such documents prior to filing and (ii) use reasonable efforts to address in each such document when so filed with the Commission such comments as such Holders reasonably shall propose prior to the filing thereof.

(b) In connection with a Piggyback Registration, Dynegy will at least two (2) Business Days prior to the anticipated filing of the initial Registration Statement that identifies the Holders and any related Prospectus or any amendment or supplement thereto (other than amendments and supplements that do not materially alter the previous disclosure or do nothing more than name Holders and provide information with respect thereto), (i) furnish to such Holders copies of all Registration Statements that identify the Holders and any related Prospectus or any amendment or supplement thereto (other than amendments and supplements that do not materially alter the previous disclosure or do nothing more than name Holders and provide information with respect thereto) prior to filing and (ii) use reasonable best efforts to address in each such document when so filed with the Commission such comments as such Holders reasonably shall propose prior to the filing thereof.

(c) Dynegy will use reasonable best efforts to as promptly as reasonably practicable (i) prepare and file with the Commission such amendments, including post-effective amendments, and supplements to each Registration Statement and the Prospectus used in connection therewith as may be necessary under applicable Law to keep such Registration Statement continuously effective with respect to the Disposition of all Registrable Securities covered thereby for its Effectiveness Period (or, with respect to a Shelf Registration, the Shelf Period) and, subject to the limitations contained in this Agreement, prepare and file with the Commission such additional Registration Statements in order to register for resale under the Securities Act all of the Registrable Securities held by the Holders; (ii) cause the related Prospectus to be amended or supplemented by any required prospectus supplement, and as so supplemented or amended to be filed pursuant to Rule 424; and (iii) respond to any comments received from the Commission with respect to each Registration Statement or any amendment thereto and, as promptly as reasonably practicable provide such Holders true and complete copies of all correspondence from and to the Commission relating to such Registration Statement that pertains to such Holders as selling Holders but not any comments that would result in the disclosure to such Holders of material and non-public information concerning Dynegy.

(d) Dynegy will comply in all material respects with the provisions of the Securities Act and the Exchange Act with respect to the Registration Statements and the Disposition of all Registrable Securities covered by each Registration Statement.

(e) Dynegy will notify such Holders who are included in a Registration Statement as promptly as reasonably practicable: (i)(A) when a Prospectus or any prospectus supplement or post-effective amendment to a Registration Statement in which such Holder is included has been filed; (B) when the Commission notifies Dynegy whether there will be a “review” of such Registration Statement and whenever the Commission comments in writing on such Registration Statement (in which case Dynegy shall provide true and complete copies thereof and all written responses thereto to each of such Holders that pertain to such Holders as selling Holders); and (C) with respect to each such Registration Statement or any post-effective amendment thereto, when the same has been declared effective; (ii) of any request by the Commission or any other federal or state governmental authority for amendments or supplements to such Registration Statement or Prospectus or for additional information that pertains to such Holders as sellers of Registrable Securities; (iii) of the issuance by the Commission of any stop order suspending the effectiveness of such Registration Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose; (iv) of the receipt by Dynegy of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction, or the initiation or threatening of any Proceeding for such purpose; and (v) of the occurrence of any event or passage of time that makes any statement made in such Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions to such Registration Statement, Prospectus or other documents so that, in the case of such Registration Statement or the Prospectus, as the case may be, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading (provided, however, that no notice by Dynegy shall be required pursuant to this clause (v) in the event that Dynegy either promptly files a prospectus supplement to update the Prospectus or a Form 8-K or other appropriate Exchange Act report that is incorporated by reference into the Registration Statement, which in either case, contains the requisite information that results in such Registration Statement no longer containing any untrue statement of material fact or omitting to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading).

(f) Dynegy will use reasonable best efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any order suspending the effectiveness of a Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, as promptly as reasonably practicable, or if any such order or suspension is made effective during any Blackout Period or Suspension Period, as promptly as reasonably practicable after such Blackout Period or Suspension Period is over.

(g) During the Effectiveness Period Dynegy will furnish to each such Holder, without charge, at least one conformed copy of each Registration Statement and each amendment thereto and all exhibits to the extent requested by such Holder (including those incorporated by reference) promptly after the filing of such documents with the Commission; provided that Dynegy will not have any obligation to provide any document pursuant to this clause that is available on the Commission’s XXXXX system.

(h) Dynegy will promptly deliver to each Holder, without charge, as many copies of each Prospectus (including each form of prospectus) authorized by Dynegy for use and each amendment or supplement thereto as such Holder may reasonably request during the Effectiveness Period. Subject to the terms of this Agreement, Dynegy consents to the use of such Prospectus and each amendment or supplement thereto by each of the selling Holders in connection with the offering and sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto.

(i) Dynegy will cooperate with such Holders to facilitate the timely preparation and delivery of book-entry interests representing Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which book-entry interests shall be free of all restrictive legends indicating that the Registrable Securities are unregistered or unqualified for resale under the Securities Act, Exchange Act or other applicable securities Laws, and to enable such Registrable Securities to be in such denominations and registered in such names as any such Holder may request in writing. In connection therewith, if required by Dynegy’s transfer agent, Dynegy will promptly, after the Effective Date of the Registration Statement, cause an opinion of counsel as to the effectiveness of the Registration Statement to be delivered to and maintained with its transfer agent, together with any other authorizations, certificates and directions required by the transfer agent which authorize and direct the transfer agent to issue such Registrable Securities without any such legend upon sale by the Holder of such Registrable Securities under the Registration Statement.

(j) Upon the occurrence of any event contemplated by Section 3(e)(v), subject to Section 2(a)(iv) and this Section 3(j), as promptly as reasonably practicable, Dynegy will prepare a supplement or amendment, including a post-effective amendment, if required by applicable Law, to the affected Registration Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, no Registration Statement nor any Prospectus will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(k) Such Holders may distribute the Registrable Securities by means of an underwritten offering; provided that (i) in the case of a Demand Registration or Shelf Registration, the Initiating Holder provides written notice to Dynegy of its intention to distribute Registrable Securities by means of an underwritten offering, which for the avoidance of doubt in the case of a Demand Registration, may be made at a date later than the original Demand Notice (the “Underwritten Offering Notice” and such underwritten offering being referred to herein as an “Underwritten Offering”), and, in the case of a Piggyback Registration, the electing Holders must include their Registrable Securities in an underwritten offering if the Piggyback Notice so requires, (ii) the right of any Holder to include such Holder’s Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein, (iii) the managing underwriter or managing underwriters thereof shall be designated by the Initiating Holder in the case of a Demand Registration and the Holders in the case of a Shelf Registration (provided, however, that such designated managing underwriter or managing underwriters shall be reasonably acceptable to Dynegy), by Dynegy in the case of a registration

initiated by Dynegy or by such other holder in the case of a registration initiated by another holder, (iv) each Holder participating in such underwritten offering agrees to enter into an underwriting agreement in customary form and sell such Holder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the Persons entitled to select the managing underwriter or managing underwriters hereunder and (v) each Holder participating in such underwritten offering completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements. Dynegy hereby agrees with each Holder that, in connection with any Underwritten Offering in accordance with the terms hereof, it will negotiate in good faith and execute all indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements. If, in the case of an Underwritten Offering, the managing underwriter advises Dynegy that the inclusion of all of the Holders’ Registrable Securities in the subject Underwritten Offering would likely have an adverse effect in any material respect on the price, timing or distribution of Registrable Securities proposed to be included in such Underwritten Offering, then Dynegy shall so advise all Holders of Registrable Securities that would otherwise be underwritten pursuant hereto, and the number of shares of Common Stock that may be included in the Underwritten Offering shall be allocated to the Holders on a pro rata basis based on the number of Registrable Securities held by all such Holders (including the Initiating Holders). Any Registrable Securities excluded from such Underwritten Offering shall be withdrawn from the Underwritten Offering. In the event that the managing underwriter limits the number of Registrable Securities to be included in the Underwritten Offering pursuant to this Section 3(k) such that at least one-half (1/2) of the aggregate Registrable Securities set forth in such Holders’ written requests pursuant to this Section 3(k) are included in the Underwritten Offering, such Underwritten Offering shall be considered to be a Demand Registration for purposes of the limitations set forth in Section 2(a)(iii) and an Underwritten Offering for purposes of the limitations set forth in this Section 3(k). In the case of an Underwritten Offering, the price, underwriting discount and other financial terms for the Registrable Securities shall be determined by the Holders. In addition, in the case of any Underwritten Offering, each of the Holders may withdraw all or part of their request to participate in the registration after being advised of such price, discount and other terms and shall not be required to enter into any agreements or documentation that would require otherwise. Dynegy shall not be obligated to take any action to effect any Underwritten Offering (i) if an Underwritten Offering (including an Underwritten Shelf Takedown) was consummated within the preceding forty-five (45) days (unless otherwise consented to by Dynegy and approved by Dynegy’s Board) or (ii) during a Blackout Period.

(l) In the case of an Underwritten Offering, upon the request of the applicable underwriter or underwriters, Dynegy will obtain for delivery to such underwriter or underwriters an opinion or opinions from counsel for Dynegy dated the date of the closing under the underwriting agreement, in customary form, scope and substance.

(m) In the case of an Underwritten Offering, upon the request of the applicable underwriter or underwriters, (a) Dynegy shall obtain for delivery to the managing underwriter or underwriters, with copies to the Holders, a cold comfort letter from Dynegy’s independent certified public accountants or independent auditors (and, if necessary, any other independent certified public accountants or independent auditors of any subsidiary of Dynegy or any business acquired by Dynegy for which financial statements and financial data are, or are required to be,

included in the Registration Statement) in customary form and covering such matters of the type customarily covered by cold comfort letters as the managing underwriter or underwriters reasonably request, dated the date of execution of the underwriting agreement and brought down to the closing under the underwriting agreement and (b) Dynegy shall obtain the required consents from Dynegy’s independent certified public accountants and, if applicable, independent auditors to include the accountants’ or auditors’ report, as applicable, relating to the specified financial statements in the Registration Statement and to be named as an expert in the Registration Statement.

(n) Dynegy shall reasonably cooperate with each Holder and each underwriter, if any, participating in the disposition of such Registrable Securities and their respective counsel in connection with any filings required to be made with FINRA.

(o) Dynegy shall use its reasonable best efforts to comply with all applicable securities laws and make available to its security holders, as soon as reasonably practicable, an earnings statement satisfying the provisions of Section 11(a) of the Securities Act and the rules and regulations promulgated thereunder.

(p) Dynegy shall provide and cause to be maintained a transfer agent and registrar for all Registrable Securities covered by the applicable Registration Statement from and after a date not later than the effective date of such Registration Statement.

(q) Dynegy shall use its best efforts to cause all Registrable Securities covered by the applicable Registration Statement to be listed on the securities exchange on which the Common Stock is then listed.

(r) In the event such Holders seek to complete an Underwritten Offering, for a reasonable period prior to the filing of any Registration Statement and throughout the Effectiveness Period, Dynegy will make available upon reasonable notice at Dynegy’s principal place of business or such other reasonable place for inspection during normal business hours by the managing underwriter or managing underwriters selected in accordance with Section 3(k) such financial and other information and books and records of Dynegy, and cause the officers, employees, counsel and independent certified public accountants of Dynegy to respond to such inquiries, as shall be reasonably necessary (and in the case of counsel, not violate an attorney-client privilege in such counsel’s reasonable belief) to conduct a reasonable investigation within the meaning of Section 11 of the Securities Act.

(s) In connection with any Demand Registration, Dynegy will use reasonable best efforts to cause appropriate officers and employees to be available, on a customary basis and upon reasonable notice, to meet with prospective investors in presentations, meetings and road shows.

(t) Dynegy may require such Holders to furnish to Dynegy any other information regarding the Holder and the distribution of such securities as Dynegy reasonably determines is required to be included in any Registration Statement.

4. Registration Expenses. All Registration Expenses incident to the Parties’ performance of or compliance with their respective obligations under this Agreement or otherwise in connection with any Shelf Registration (including any Shelf Takedown), Demand Registration or Piggyback Registration (in each case, excluding any Selling Expenses) shall be borne by Dynegy, whether or not any Registrable Securities are sold pursuant to a Registration Statement; provided that Dynegy shall not be required to bear any such Registration Expenses of Holders that have withdrawn their request for registration under this Agreement such that it no longer counts as an Underwritten Offering for purposes of Section 2(b)(iii). “Registration Expenses” shall include (i) all registration and filing fees (including fees and expenses (A) with respect to filings required to be made with the Trading Market and (B) in compliance with applicable state securities or “Blue Sky” Laws), (ii) printing expenses (including expenses of printing certificates for Dynegy Securities and of printing prospectuses if the printing of prospectuses is reasonably requested by a Holder of Registrable Securities included in the Registration Statement), (iii) messenger, telephone and delivery expenses, (iv) fees and disbursements of counsel, auditors and accountants for Dynegy, (v) Securities Act liability insurance, if Dynegy so desires such insurance, (vi) fees and expenses of all other Persons retained by Dynegy in connection with the consummation of the transactions contemplated by this Agreement and (vii) all expenses relating to marketing the sale of the Registrable Securities, including expenses related to conducting a “road show.” In addition, Dynegy shall be responsible for all of its expenses incurred in connection with the consummation of the transactions contemplated by this Agreement (including expenses payable to third parties and including all salaries and expenses of their officers and employees performing legal or accounting duties), the expense of any annual audit and the fees and expenses incurred in connection with the listing of the Registrable Securities on the Trading Market.

5. Indemnification.

(a) Dynegy shall indemnify and hold harmless each Holder, its Affiliates and each of their respective officers and directors and any Person who controls any such Holder (within the meaning of the Securities Act) and any agent thereof (collectively, “Holder Indemnified Persons”), to the fullest extent permitted by applicable Law, from and against any and all losses, claims, damages, liabilities, joint or several, costs (including reasonable costs of preparation and reasonable attorneys’ fees) and expenses, judgments, fines, penalties, interest, settlements or other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any Holder Indemnified Person may be involved, or is threatened to be involved, as a party or otherwise, under the Securities Act or otherwise (collectively, “Losses”), as incurred, arising out of or relating to any untrue or alleged untrue statement of a material fact contained in any Registration Statement under which any Registrable Securities were registered, in any preliminary prospectus (if Dynegy authorized the use of such preliminary prospectus prior to the Effective Date), or in any summary or final prospectus or free writing prospectus (if such free writing prospectus was authorized for use by Dynegy) or in any amendment or supplement thereto (if used during the period Dynegy is required to keep the Registration Statement current), or arising out of, based upon or resulting from the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein (in the case of any preliminary prospectus, final prospectus or free writing prospectus, in the light of the circumstances in which they were made) not misleading; provided, however, that Dynegy shall

not be liable to any Holder Indemnified Person to the extent that any such claim arises out of, is based upon or results from (i) an untrue or alleged untrue statement or omission or alleged omission made in such Registration Statement, such preliminary, summary or final prospectus or free writing prospectus or such amendment or supplement, in reliance upon and in conformity with written information furnished to Dynegy by or on behalf of such Holder Indemnified Person or any underwriter specifically for use in the preparation thereof or (ii) any Disposition of Registrable Securities during a Blackout Period or a Suspension Period. Dynegy shall notify the Holders promptly of the institution, threat or assertion of any Proceeding of which Dynegy is aware in connection with the transactions contemplated by this Agreement.

(b) In connection with any Registration Statement in which a Holder participates, such Holder shall indemnify and hold harmless Dynegy, its Affiliates and each of their respective officers, directors and any Person who controls Dynegy (within the meaning of the Securities Act) and any agent thereof (collectively, the “Dynegy Indemnified Persons”), to the fullest extent permitted by applicable Law, from and against any and all Losses as incurred, arising out of or relating to any untrue or alleged untrue statement of a material fact contained in any such Registration Statement, in any preliminary prospectus (if used prior to the Effective Date of such Registration Statement), or in any summary or final prospectus or free writing prospectus or in any amendment or supplement thereto (if used during the period Dynegy is required to keep the Registration Statement current), or arising out of, based upon or resulting from the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein (in the case of any preliminary prospectus, final prospectus or free writing prospectus, in the light of the circumstances in which they were made) not misleading, but only to the extent that the same are made in reliance and in conformity with information relating to the Holder furnished in writing to Dynegy by such Holder for use therein.

(c) Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim or there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent will not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel (in addition to any local counsel) for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party there may be one or more legal or equitable defenses available to such indemnified party that are in addition to or may conflict with those available to another indemnified party with respect to such claim. Failure to give prompt written notice shall not release the indemnifying party from its obligations hereunder.

(d)

(i) If a claim for indemnification under Section 5(a) or 5(b) is unavailable to an indemnified party (by reason of public policy or otherwise), then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Losses, in such proportion as is appropriate to reflect the relative fault of the indemnifying party and indemnified party in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such indemnifying party or indemnified party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a party as a result of any Losses shall be deemed to include, subject to the limitations set forth in Section 5(d)(ii), any reasonable attorneys’ or other reasonable fees or expenses incurred by such party in connection with any Proceeding to the extent such party would have been indemnified for such fees or expenses if the indemnification provided for in this Section 5 was available to such party in accordance with its terms.

(ii) The Parties agree that it would not be just and equitable if contribution pursuant to this Section 5(d) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in Section 5(d)(i). Notwithstanding the provisions of this Section 5(d), no Holder shall be required to contribute, in the aggregate, any amount in excess of the amount by which the proceeds actually received by such Holder from the sale of the Registrable Securities subject to the Proceeding exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(e) Notwithstanding anything to the contrary herein, this Section 5 shall survive any termination or expiration of this Agreement indefinitely.

6. Facilitation of Sales Under Rule 144. Dynegy covenants that it will file the reports required to be filed by it under the Exchange Act and the Securities Act (or, if Dynegy is not required to file such reports, it will, upon the reasonable request a Holder, make publicly available such necessary information for so long as necessary to permit sales pursuant to Rules 144 under the Securities Act), and it will take such further action as any Holder may reasonably request, all to the extent required from time to time to enable the Holders to sell Registrable Securities without Registration under the Securities Act within the limitation of the exemptions provided by (i) Rule 144 under the Securities Act or (ii) any similar rule or regulation hereafter adopted by the Commission. Upon the reasonable request of a Holder, Dynegy will deliver to such Holder a written statement as to whether it has complied with such requirements and, if not, the specifics thereof.

7. Standstill; Lock-Up.

(a) For a period beginning on the date hereof and ending on the six (6) month anniversary of the first date that Purchaser and any Controlled Affiliates cease to Beneficially Own in the aggregate at least 10% of the then-outstanding Common Stock, without the prior written consent of Dynegy, Purchaser agrees that it shall not, and shall cause its Affiliates and its and their Representatives not to, in each case, individually, collectively or in concert with any other Persons, directly or indirectly:

(i) acquire or agree to acquire from any Person, directly or indirectly, by purchase or merger, through the acquisition of control of another Person, by joining a partnership, limited partnership or other “group” (within the meaning of Section 13(d)(3) of the Exchange Act) or otherwise, Beneficial Ownership of any Equity Securities or debt or hybrid securities of Dynegy, or direct or indirect rights (including convertible securities), options or warrants to acquire such Beneficial Ownership (collectively, the “Securities”); provided, however, that no such acquisition or agreement to acquire shall be deemed to occur solely due to (A) a stock split, reverse stock split, reclassification, reorganization or other transaction by Dynegy affecting any class of the outstanding Equity Securities generally, (B) a dividend of Securities or other pro rata distribution by Dynegy to holders of its outstanding Equity Securities or (C) a purchase by Purchaser or any Controlled Affiliate of Securities of Dynegy pursuant to Section 7(d) or Section 8;

(ii) except as provided in Section 9 and Section 11, make, or in any way participate in, directly or indirectly, any “solicitation” of “proxies” to vote (as such terms are used in the Regulation 14A promulgated under the Exchange Act), become a “participant” in, or encourage, support or aid any other Person to become a “participant,” in any “election contest” (as such terms are defined in Rule 14a-11 promulgated under the Exchange Act) or seek to advise or influence any Stockholders with respect to the voting of any voting Securities of Dynegy, in each case with respect to Dynegy;

(iii) form, join or in any way participate in the formation of, a “group” (within the meaning of Section 13(d)(3) of the Exchange Act) with respect to any voting securities of Dynegy other than a “group” that consists solely of the Controlled Affiliates;

(iv) deposit any Securities into a voting trust, or subject any Securities to any voting or pooling agreement or arrangement with respect to the voting of such Securities, or other agreement or arrangement having similar effect;

(v) participate in any tender offer, exchange offer, merger, acquisition, share exchange or other similar business combination or any Change of Control Transaction involving Dynegy or any of its Subsidiaries, or any recapitalization, restructuring, liquidation, Disposition or dissolution of, or other extraordinary transaction involving, Dynegy, any of its Subsidiaries or any material portion of their businesses (but excluding, in each case, any Disposition of any Securities of Dynegy held by Purchaser or any of its Affiliates otherwise permitted by the terms of this Agreement);

(vi) make any public disclosure, or take any action which would reasonably be expected to require Dynegy to make any public disclosure, with respect to the intention of Purchaser or its Affiliates to take any action that would be prohibited by this Section 7(a);

(vii) publicly disclose any intention, plan or arrangement inconsistent with any provision of this Section 7(a);

(viii) propose, or agree to, or enter into any discussions, negotiations or arrangements with, or provide any Confidential Information to, or act in concert with, any other Person (other than Representatives of Purchaser in compliance with Section 13) for the purpose of taking any action that would be prohibited by this Section 7(a); or

(ix) request that Dynegy (or any directors, officers, employees or agents of Dynegy), directly or indirectly, amend, waive or modify any provision of this Section 7(a), unless such request is made confidentially to the Board.

Notwithstanding the foregoing, nothing in this Section 7(a) shall (i) prohibit or restrict in any respect any Designated Director from participating as a member of the Board and committees thereof in his or her capacity as such to the extent permitted by Law and exercising his or her fiduciary duties in connection therewith, (ii) restrict the rights of Purchaser or its Affiliates or its or their respective Representatives under any of the other Delta Documents, (iii) prohibit the taking of any action that is otherwise expressly permitted pursuant to the terms of this Agreement (including Sections 7(d), 8, 9 and 11 of this Agreement) or (iv) prohibit the taking of any action that is approved by the Board. Furthermore, and without limiting Section 11, the provisions of this Section 7(a) shall automatically terminate and be inoperative and of no force or effect if any Person or its Affiliates (w) enters into a definitive and binding agreement with Dynegy providing for a Change of Control Transaction, (x) commences a tender offer or exchange offer with respect to Equity Securities representing 40% or more of the voting power of the Company and Dynegy does not recommend within ten (10) Business Days of the commencement of such tender offer or exchange offer that the Stockholders not tender their Equity Securities pursuant to such tender offer or exchange offer, or (y) enters into an agreement or commences a proxy solicitation in which such Person or its Affiliates would acquire the ability to elect a majority of the Board and Dynegy does not recommend against such agreement or proxy solicitation within ten (10) Business Days of the entry into such agreement or the commencement of such proxy solicitation.

(b) Notwithstanding anything to the contrary in this Agreement, except for any Disposition of Shares to a Controlled Affiliate pursuant to Section 7(d), for a period of six (6) months after the date hereof (the “Lock-Up Period”) without the prior written consent of Dynegy, Purchaser agrees not to offer, sell, contract to sell, pledge or otherwise Dispose of, or enter into any transaction which is designed to, or might reasonably be expected to, result in the Disposition of Shares (whether by actual Disposition or effective economic Disposition due to cash settlement or otherwise) by Purchaser or any of its Affiliates, directly or indirectly, including by establishing or increasing a put equivalent position or liquidating or decreasing a call equivalent position within the meaning of Section 16 of the Exchange Act with respect to, any Shares or any securities that are convertible into, or exercisable or exchangeable for, or that

represent the right to receive, the Shares, or publicly announce an intention to effect any such transaction; provided that nothing in this Section 7(b) shall restrict or otherwise modify the obligations of Dynegy set forth in Section 2(a)(i).

(c) Until the first date that Purchaser and any Controlled Affiliates cease to Beneficially Own in the aggregate at least 5% of the then-outstanding Common Stock, Purchaser shall not, and shall cause its Affiliates not to, enter into any Hedging Arrangements.

(d) Purchaser may Dispose of Shares to one or more Controlled Affiliates (and such Controlled Affiliates may then Dispose of Shares to one or more Controlled Affiliates), provided that such transferee Controlled Affiliate agrees in writing to be bound by the terms and conditions, including the restrictions with respect to Purchaser set forth in this Agreement.

(e) Notwithstanding anything to the contrary in this Agreement, until the first date that Purchaser and any Controlled Affiliates cease to Beneficially Own in the aggregate at least 10% of the then-outstanding Common Stock, Purchaser shall not Dispose of any Shares (other than to a Controlled Affiliate pursuant to Section 7(d)) except: (i) pursuant to a registered offering under the Securities Act; (ii) pursuant to Rule 144 (in accordance with the volume and procedural limitations set forth in Rule 144 to the extent legally applicable to Purchaser at the time of the sale); or (iii) to any Person or group that, after giving effect to such Disposition, will not be reasonably expected (after reasonable investigation by Purchaser) to Beneficially Own 9.9% or more of the then-outstanding Common Stock.

(f) For so long as any Holder and its Affiliates Beneficially Own in the aggregate at least 5% of the then-outstanding Common Stock, in connection with any underwritten offering of Common Stock, such Holder and its Affiliates will agree, upon the request of Dynegy, to enter into a customary lock-up agreement with the managing underwriters of such offering, provided, however, that the lock-up period under such agreement shall not exceed ninety (90) days and shall be no more restrictive than any lock-up arrangement entered into by the officers and directors of Dynegy or any other Stockholder that holds at least 5% of the then-outstanding Common Stock.

(g) Until the first date that Purchaser and any Controlled Affiliates cease to Beneficially Own in the aggregate 10% or more of the then-outstanding Common Stock, Purchaser shall not Dispose of any Shares to any Person pursuant to Section 7(d) or Section 7(e)(iii) and shall cause its Affiliates not to Dispose of Beneficial Ownership in any Shares (i) if such Disposition is reasonably likely to require the approval of Federal Energy Regulatory Commission (the “FERC”) under Section 203 of the Federal Power Act (the “FPA”), or the approval of or notification to any state utility agency under the applicable Laws of such state, and the FERC or the relevant state utility agency shall have not issued an order approving such proposed Disposition or accepting any such required notification (or otherwise indicating in writing that no further action will be taken with respect to any required notification), as applicable, (ii) if such Disposition is reasonably likely to result in the loss of market-based rate authority, or a requirement by the FERC to implement mitigation measures in order to retain such authority, by Dynegy, any of its Subsidiaries, or any “affiliate” of Dynegy as defined in 18 C.F.R. § 35.36 or otherwise for market-based rate purposes under Section 205 of the FPA, or (iii)

if, immediately following such Disposition, Dynegy or any member of its “holding company system” as defined in 18 C.F.R. § 366.1 that is, immediately prior to such Disposition, exempt from regulation pursuant to 18 C.F.R. § 366.3(a), would reasonably be likely to cease to be exempt from regulation pursuant to 18 C.F.R. § 366.3(a) immediately following such Disposition.

8. Right of First Refusal.

(a) Until the earlier of (i) first date that Purchaser and any Controlled Affiliates cease to Beneficially Own in the aggregate at least 7.5% of the then-outstanding Common Stock, and (ii) three (3) years after the date of this Agreement, Dynegy shall not issue any Equity Securities that would rank senior to the Common Stock with respect to dividends and distributions upon liquidation other than pursuant to an Excluded Issuance (such issuance, a “Proposed Covered Issuance”) unless Dynegy has first complied with the terms of this Section 8. Prior to any Proposed Covered Issuance, Dynegy shall provide written notice to Purchaser (the “ROFR Notice”) describing in reasonable detail the Proposed Covered Issuance, including the number and type of Equity Securities to be issued in the Proposed Covered Issuance (the “Proposed Securities”), the consideration to be paid for the Proposed Securities, whether the Proposed Covered Issuance will be registered under the Securities Act and, if not registered under the Securities Act, the parties, if known, to the Proposed Covered Issuance and any other material conditions or contingencies relating to the Proposed Covered Issuance. Purchaser shall have fifteen (15) days after the delivery of the ROFR Notice (the “ROFR Consideration Period”) to deliver written notice (such notice as such may be amended pursuant to Section 8(b), a “ROFR Election Notice”) to Dynegy stating that Purchaser intends to purchase up to its pro rata portion of the Proposed Securities based on the percentage of Dynegy’s then outstanding Common Stock Beneficially Owned by Purchaser or any Controlled Affiliate on the terms, conditions and contingencies set forth in the ROFR Notice, and Purchaser shall not have the right to purchase any such Proposed Securities in excess of such pro rata portion.

(b) Notwithstanding anything to the contrary contained in Section 8(a), in the event that Purchaser delivers a ROFR Election Notice electing to purchase an amount of Proposed Securities that would require the approval of the Stockholders pursuant to Section 312.03 of the NYSE Listed Company Manual (“ROFR Shareholder Approval”), Dynegy shall, within three (3) Business Days of receiving such ROFR Election Notice, provide written notice to Purchaser (the “ROFR Shareholder Approval Notice”) setting forth the amount of Proposed Securities that cannot be issued without such ROFR Shareholder Approval (the “Excess Proposed Securities”). In such case, Purchaser shall have the right, within five (5) Business Days of receiving such ROFR Shareholder Approval Notice, to deliver a written notice to Dynegy withdrawing its ROFR Election Notice or amending its ROFR Election Notice to alter the amount of Proposed Securities it is electing to purchase. To the extent that Purchaser does not withdraw its ROFR Election Notice, or otherwise amend its ROFR Election Notice to remove any Excess Proposed Securities, then Dynegy shall be required to issue to Purchaser in place of each Excess Proposed Security included in the ROFR Election Notice an Equity Security that is identical in all respects to such Excess Proposed Security except that such Equity Security shall be a non-voting Equity Security that will automatically convert into a voting Equity Security upon receipt of the requisite ROFR Shareholder Approval (such that upon receipt of ROFR

Shareholder Approval, such Equity Security will automatically convert and be identical in all respects to the Proposed Securities).

(c) If Purchaser delivers the ROFR Election Notice prior to the expiration of the ROFR Consideration Period, the Parties shall use reasonable best efforts for a period of forty-five (45) days (the “ROFR Negotiation Period”) after delivery of the ROFR Election Notice to negotiate in good faith a definitive agreement or agreements providing for the sale and issuance of the Proposed Securities Purchaser has determined to purchase in the ROFR Election Notice at the price and on the other terms, conditions and contingencies set forth in the ROFR Notice and as set forth in Section 8(b) as promptly as practicable. In the event that ROFR Shareholder Approval is required in connection with any such Proposed Covered Issuance, Dynegy will use reasonable best efforts to secure such ROFR Shareholder Approval as promptly as reasonably practicable; provided, however, that Dynegy shall not be required to submit any proposal to obtain the ROFR Shareholder Approval to the Stockholders until the next annual meeting of Stockholders occurring after the delivery of the ROFR Election Notice; provided, further, that if Purchaser delivers such ROFR Election Notice within seventy-five (75) days prior to the one year anniversary of the date of Dynegy’s prior annual meeting of Stockholders, Dynegy shall not be required to submit a proposal to obtain the ROFR Shareholder Approval until the annual meeting of Stockholders occurring in the calendar year after the calendar year in which Purchaser delivered such ROFR Election Notice.

(d) If (i) Purchaser does not deliver the ROFR Election Notice prior to the expiration of the ROFR Consideration Period, or withdraws its ROFR Election Notice pursuant to Section 8(b), or (ii) Purchaser delivers the ROFR Election Notice prior to the expiration of the ROFR Consideration Period but the Parties do not execute a definitive agreement providing for the Proposed Covered Issuance prior to the expiration of the ROFR Negotiation Period, then for a period of one hundred and twenty (120) days after the expiration of the ROFR Consideration Period, the date on which the ROFR Election Notice is withdrawn or the expiration of the ROFR Negotiation Period, as applicable, Dynegy may consummate the Proposed Covered Issuance with Persons other than Purchaser on terms, conditions and contingencies that no more favorable, in the aggregate, to such other Persons than the terms, conditions and contingencies set forth in the ROFR Notice. If Dynegy does not consummate such Proposed Covered Issuance within such one hundred and twenty (120) day period, then Dynegy shall not thereafter consummate such Proposed Covered Issuance without first offering the Proposed Securities to Purchaser in the manner described in this Section 8.

(e) Notwithstanding anything to the contrary set forth in this Section 8, Purchaser shall be permitted to assign any of its rights under this Section 8 (including its right to acquire any of the Proposed Securities) to one or more Controlled Affiliates that agree in writing to be bound by the terms and conditions of this Agreement.

(f) For purposes of this Section 8, “Excluded Issuance” means any of the following:

(i) the issuance of Equity Securities pursuant to any employee benefits or other compensation plan approved by the Board and the Stockholders;

(ii) the issuance of Equity Securities other than for cash consideration pursuant to a merger, consolidation, acquisition, Disposition or similar business combination approved by the Board;

(iii) the issuance of Equity Securities upon any stock dividend, stock split or other pro rata distribution, subdivision or combination of securities or other recapitalization of Dynegy;

(iv) the issuance of Equity Securities upon conversion of the Dynegy Preferred Stock outstanding as of the date hereof in accordance with its terms;

(v) the issuance of Equity Securities upon the exercise of the Dynegy Warrants outstanding as of the date hereof in accordance with their terms; or

(vi) the issuance of Equity Securities issued pursuant to the terms of a “poison pill” or other stockholder rights plan approved by the Board.

9. Director Designation Rights.

(a) Board Representation.

(i) On the date hereof, the Board shall adopt resolutions that (A) increase the number of natural persons that constitute the whole Board by one (1) person and (B) fill the vacancy created by virtue of such increase in the size of the Board with Xxxxx Xxxxxx (the “Initial Appointment”). For the avoidance of doubt, (1) Dynegy acknowledges and agrees that Xxxxx Xxxxxx meets all of the qualifications set forth in Section 9(a)(ii) and has provided all of the requisite information necessary to be admitted to the Board on the date hereof and (2) Xxxxx Xxxxxx shall be considered a Designated Director.

(ii) Until a Termination Event, Purchaser shall have the right to nominate an individual for election to the Board, in each case pursuant to the Dynegy Organizational Documents, who must in the reasonable, good faith judgment of the Corporate Governance and Nominating Committee of the Board, (1) have the requisite skill and experience to serve as a director of a publicly traded company, (2) not be prohibited or disqualified from serving as a director of Dynegy pursuant to the Dynegy Bylaws (as in effect as of the date hereof) or any rule or regulation of the Commission, the NYSE (or any other principal stock exchange or market upon which the Common Stock may be listed) or by applicable Law and (3) otherwise be reasonably acceptable to the Corporate Governance and Nominating Committee of the Board (the “Designated Director”). Purchaser shall, and shall cause the Designated Director to, timely provide Dynegy with accurate and complete information relating to Purchaser and the Designated Director that may be required to be disclosed by Dynegy under the Exchange Act. In addition, at Dynegy’s request, Purchaser shall cause the Designated Director to complete and execute Dynegy’s standard director and officer questionnaire and provide such other information as Dynegy may reasonably request prior to being admitted to the Board or standing for reelection at an annual meeting of Stockholders or at such other time as may be requested by Dynegy; provided that, in each case, all such information is generally required to be delivered to Dynegy by the other outside directors of Dynegy.

(iii) The Designated Director will hold office until his or her term expires and such Designated Director’s successor has been duly elected and qualified or until such Designated Director’s earlier death, resignation or removal.

(iv) Following the Initial Appointment, in order to designate an individual as the Designated Director, Purchaser must deliver to Dynegy a written notice in accordance with the notice provisions set forth in Section 14(d), which notice shall include (A) the name, age, business address and residence address of such designee, (B) a current resume and curriculum vitae of such designee and (C) a statement describing such designee’s qualifications.

(v) Prior to a Termination Event:

(A) in connection with each annual meeting of Stockholders, and subject to the conditions of Section 9(a)(ii) of this Agreement, Dynegy shall nominate the Designated Director for election or reelection, as applicable, to the Board and shall use its reasonable best efforts, and take all reasonable and lawful actions necessary or advisable, to cause the Board to recommend that the Stockholders vote “FOR” the election of the Designated Director;

(B) upon written notice from Dynegy to Purchaser that a Resignation Event has occurred, which notice shall set forth in reasonable detail the facts and circumstances constituting the Resignation Event, Purchaser will cause the Designated Director then serving as a member of the Board to resign as a member of the Board within five (5) Business Days of such written notice; and

(C) any vacancy caused by the death, disability, removal or resignation of the Designated Director shall be filled by the Board with an individual designated by Purchaser who, subject to the conditions of Section 9(a)(ii) of this Agreement, shall become the Designated Director.

(vi) Any action by Purchaser to designate or replace the Designated Director shall be evidenced in writing delivered to Dynegy and shall be signed by or on behalf of Purchaser.

(vii) Prior to designating a Designated Director, Purchaser shall, to the extent requested in writing by Dynegy, enter into a written agreement in a form reasonably satisfactory to Dynegy with the Designated Director whereby such Designated Director agrees to resign as a member of the Board upon a Resignation Event, a Termination Event or at Purchaser’s request, as applicable. Purchaser acknowledges and agrees that such an agreement is in the best interest of Dynegy and Purchaser, and that Dynegy shall be a third-party beneficiary of the terms and conditions of such an agreement, and Dynegy shall have the right to enforce such an agreement to the same extent as the parties thereto.

(viii) Dynegy shall notify the Designated Director of all regular and special meetings of the Board and of all regular and special meetings of any committee of the Board of which the Designated Director is a member. Dynegy shall provide the Designated

Director with copies of all notices, minutes, consents and other materials provided to all other members of the Board concurrently as such materials are provided to the other members.

(b) Termination of Director Designation Rights. Upon the occurrence of a Termination Event, Purchaser’s right to designate, and Dynegy’s obligation to nominate, the Designated Director shall automatically terminate, and Purchaser shall cause the Designated Director then serving as a member of the Board, promptly upon (and in any event within five (5) Business Days following) receipt of a written request from Dynegy, to resign as a member of the Board. In the event Dynegy does not request that the Designated Director be caused to resign upon occurrence of a Termination Event, such Designated Director will no longer be considered a designee of Purchaser and will be subject to election and reelection in accordance with the Dynegy Bylaws. Purchaser shall have the right at any time to cause the Designated Director to resign as a member of the Board and to waive its rights to designate a nominee for election to the Board.

(c) Director Indemnification. At all times while the Designated Director is serving as a member of the Board, and following any such Designated Director’s death, resignation, removal or other cessation as a director in such former Designated Director’s capacity as a former director, each Designated Director shall be entitled to all rights to indemnification and exculpation as are then made available to any other member (or former member) of the Board. In addition, for so long as Dynegy maintains directors and officers liability insurance, Dynegy shall include the Designated Director as an “insured” for all purposes under such insurance policy for so long as such Designated Director is a director of Dynegy and for the same period as other former directors of Dynegy when such Designated Director ceases to be a director of Dynegy. Each Designated Director is an express third-party beneficiary of the terms of this Section 9(c).

(d) Director Compensation. In the event that the Designated Director is an employee of ECP or any Affiliate of ECP that is a Fund Manager, Fund Advisor or Fund (but excluding, for the avoidance of doubt, any portfolio company of any Fund) (an “ECP Employee”), such Designated Director shall not be entitled to compensation and benefits but shall be entitled to receive at least the same reimbursement for fees and expenses as other outside directors and, in any event, shall be entitled to reimbursement for documented, reasonable out-of-pocket fees and expenses incurred in connection with such Designated Director’s service on the Board or any committee thereof (including in respect of travel, lodging, etc.). In the event that the Designated Director is not an ECP Employee, then such Designated Director shall, at such Designated Director’s election, be entitled to receive at least the same compensation and benefits as other outside directors of Dynegy. Each Designated Director is an express third-party beneficiary of the terms of this Section 9(d).

10. Corporate Opportunities. Dynegy, on behalf of itself and its Subsidiaries, (a) acknowledges and affirms that Purchaser, ECP and its and their respective Affiliates, employees, directors, partners and members, including any Designated Directors (the “ECP Group”) (i) have participated (directly or indirectly) and will continue to participate (directly or indirectly) in private equity, venture capital and other direct investments in corporations, joint ventures, limited liability companies and other entities (“Other Investments”), including Other Investments engaged in various aspects of the power generating business (and related services businesses)

that may, are or will be competitive with Dynegy’s business or that could be suitable for Dynegy’s interest, (ii) have interests in, participate with, aid and maintain seats on the boards of directors or similar governing bodies of, Other Investments, (iii) may develop or become aware of business opportunities for Other Investments and (iv) may or will, as a result of or arising from the matters referenced in this Section 10, the nature of the Affiliated Parties’ businesses and other factors, have conflicts of interest or potential conflicts of interest, (b) hereby renounces and disclaims any interest or expectancy in any business opportunity, including any Other Investments or any other opportunities that may arise in connection with the circumstances described in the foregoing clauses (i)—(iv) (collectively, the “Renounced Business Opportunities”), and (c) acknowledges and affirms that no member of the ECP Group, including any Designated Director, shall have any obligation to communicate or offer any Renounced Business Opportunity to Dynegy, and any member of the ECP Group may pursue a Renounced Business Opportunity. Notwithstanding the foregoing, Dynegy does not renounce its interest in any corporate opportunity if such corporate opportunity was offered to a Designated Director solely in his or her capacity as a director of Dynegy, provided that such opportunity (i) has not been separately presented to ECP or its Affiliates or is not otherwise being independently pursued by ECP or its Affiliates (in each case whether before or after such opportunity is presented to such Designated Director) or (ii) is not disclosed to the public, in each case of clauses (i) and (ii), other than as a result of a breach of such Designated Director’s confidentiality obligations to Dynegy or a breach of Purchaser’s or its Representatives’ obligations under Section 13. Notwithstanding anything to the contrary in this Section 10, Dynegy shall not be prohibited from pursuing any Renounced Business Opportunity as a result of this Section 10.

11. Voting Arrangements. Until the first date that Purchaser and any Controlled Affiliates cease to Beneficially Own at least 10% of the then-outstanding Common Stock, at any annual or special meeting (or adjournment thereof) of the Stockholders, Purchaser shall vote, or cause to be voted, the Shares (and any other shares of Common Stock that Purchaser or its Affiliates Beneficially Own after the date hereof) as recommended by the Board. This Section 11 shall terminate upon the consummation of a Change of Control Transaction.

12. Section 16 Filings. Purchaser shall be solely responsible for making, or causing to be made, any filings with the Commission required to made by the Designated Director, Purchaser or any of their respective Affiliates under Section 16 of the Exchange Act (including any filing on Form 3, Form 4 or Form 5) as a result of the Beneficial Ownership of any shares of Common Stock, or any securities that are convertible into, or exercisable or exchangeable for, or that represent the right to receive, shares of Common Stock, by Purchaser and any Controlled Affiliates; provided that Dynegy shall cooperate with Purchaser in connection therewith, including by providing such information as may be reasonably requested by Purchaser in connection with such filings.

13. Information Rights; Confidentiality.

(a) Until the first date that Purchaser and any Controlled Affiliate cease to Beneficially Own at least 5% of the then-outstanding Common Stock, Dynegy shall provide Purchaser with such information as Purchaser may reasonably request to the extent necessary to evaluate its investment in the Shares; provided that Dynegy may deny access to any information

and reports or portions thereof (i) if Dynegy reasonably determines that access to any such information or report could (A) result in a waiver of the attorney—client privilege (based on the advice of counsel), (B) cause Dynegy to violate obligations with respect to confidential or proprietary information of third parties (provided that Dynegy shall use reasonable efforts to make appropriate substitute arrangements under circumstances where the restrictions in clause (A) or (B) above apply) or (C) cause Dynegy to violate any applicable Laws (including antitrust Laws) or (ii) in respect of a matter in which Purchaser has a material interest (other than any such interest arising solely as a result of Purchaser’s status as a Stockholder).

(b) Purchaser agrees that Confidential Information has been and may be furnished to it. Purchaser agrees that it shall use, and shall instruct any Person to whom Confidential Information is disclosed pursuant to clause (i) below, to use such Confidential Information only in connection with Purchaser’s investment in the Shares or the other transactions contemplated by the Delta Documents and not for any other purpose. Purchaser further acknowledges and agrees that it shall not disclose any Confidential Information to any Person, except that Purchaser may disclose Confidential Information (i) to Purchaser’s Affiliates and its and their respective directors, officers, employees, members, agents, counsel, investment advisers or other representatives (collectively, “Representatives”), in each case, solely with respect to Purchaser’s investment in Dynegy and the transactions contemplated by the Delta Documents, including to the extent related to the tax treatment and tax structure of the transactions contemplated by this Agreement, the Purchase Agreement or any other Delta Document; provided that Purchaser advises any such Affiliates or Representatives of the confidential nature of the Confidential Information and causes its Affiliates, and uses its reasonable best efforts to cause its Representatives, to not disclose the Confidential Information to any Person except as permitted by this Section 13(b) or (ii) to the extent required by applicable Law (including complying with any oral or written questions, interrogatories, requests for information or documents, subpoena, civil investigative demand or similar process to which Purchaser is subject); provided that, prior to any such disclosure, Purchaser shall, to the extent legally permissible, give Dynegy reasonably prompt notice of such request(s) so that Dynegy may seek an appropriate protective order or similar relief (and Purchaser shall reasonably cooperate with such efforts by Dynegy, at Dynegy’s sole cost and expense, and shall in any event make only the minimum disclosure required by such Law); provided, further, that Purchaser, ECP and its and their respective Affiliates and Representatives shall be permitted to disclose such information regarding the direct or indirect investment in Dynegy by such Purchaser or Affiliates, the financial performance and operations of Dynegy and its Subsidiaries, and such other information relevant to such investment in Dynegy to the limited partners, investors or other direct or indirect equity owners of, or prospective investors of, Funds Affiliated with ECP or their Affiliates who are under customary duties or obligations of confidentiality. Purchaser shall be liable for any disclosure of Confidential Information by its Affiliates or Representatives in violation of this Section 13(b).

(c) Purchaser is aware, and shall advise its Representatives who are provided any Confidential Information, of the restrictions imposed by the United States securities laws on the purchase or sale of securities by any person who has received material, non-public information from the issuer of such securities and on the communication of such information to any other person when it is reasonably foreseeable that such other person is likely to purchase or sell such securities. Purchaser hereby confirms that it and its Affiliates shall, and shall instruct its

Representatives to, take any action necessary to prevent the use of any information about Dynegy in a way which violates any securities or antitrust or other applicable Law.

14. Miscellaneous.

(a) Remedies. The Parties acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached and that monetary damages, even if available, would not be an adequate remedy therefor. It is accordingly agreed the Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the performance of terms and provisions of this Agreement, without proof of actual damages (and each Party hereby waives any requirement for the securing or posting of any bond in connection with such remedy), this being in addition to any other remedy to which they are entitled at law or in equity. The Parties further agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to Law or inequitable for any reason, nor to assert that a remedy of monetary damages would provide an adequate remedy for any such breach.

(b) Discontinued Disposition. Each Holder agrees that, upon receipt of a notice from Dynegy of the occurrence of any event of the kind described in clauses (ii) through (v) of Section 3(e) (a “Suspension Notice”), such Holder will forthwith discontinue Disposition of such Registrable Securities under any Registration Statement until such Holder’s receipt of the copies of the supplemental Prospectus or amended Registration Statement as contemplated by Section 3(j) or until it is advised in writing by Dynegy that the use of the applicable Prospectus may be resumed, and, in either case, has received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such Prospectus or Registration Statement (a “Suspension Period”). Dynegy may provide appropriate stop orders to enforce the provisions of this Section 14(b).

(c) Amendments and Waivers. No provision of this Agreement may be waived or amended except in a written instrument signed by Dynegy and Purchaser. Dynegy shall provide prior notice to all Holders of any proposed waiver or amendment. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any Party to exercise any right hereunder in any manner impair the exercise of any such right.

(d) Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and shall be deemed given and effective on the earliest of (i) the date of transmission, if such notice or communication is delivered via facsimile or electronic mail as specified in this Section 14(d) prior to 5:00 p.m. (Houston, Texas time) on a Business Day, (ii) the Business Day after the date of transmission, if such notice or communication is delivered via facsimile or electronic mail as specified in this Agreement later than 5:00 p.m. (Houston, Texas time) on any date and earlier than 11:59 p.m. (Houston, Texas time) on such date, (iii) the Business Day following the date of mailing, if sent by nationally recognized overnight courier service or (iv) upon actual receipt by the Party to

In the event that any signature is delivered by facsimile or electronic mail transmission, such signature shall create a valid binding obligation of the Party executing (or on whose behalf such signature is executed) the same with the same force and effect as if such signature delivered by facsimile or electronic mail transmission were the original thereof.

(h) Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. This Agreement, and all claims or causes of action (whether in contract, tort or otherwise) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance of this Agreement (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Agreement), shall be governed by, and construed in accordance with, the internal Laws of the State of Delaware, without reference to the choice of law provisions thereof. All claims, causes of action, suits, actions or proceedings shall be raised to and exclusively determined by the Court of Chancery for the State of Delaware or, if such court disclaims jurisdiction, the U.S. District Court for the District of Delaware or, if such court disclaims jurisdiction, the courts of the State of Delaware, and in each case, any appellate court from any decision thereof, to whose exclusive jurisdiction and venue the Parties unconditionally consent and submit. Service of process in connection with any such claim, cause of action suit, action or proceeding may be served on each Party anywhere in the world by the same methods as are specified for the giving of notices under this Agreement. Each of the Parties irrevocably waives any objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. EACH OF THE PARTIES HEREBY WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS AGREEMENT AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER.

(i) Cumulative Remedies. The remedies provided herein are cumulative and not exclusive of any remedies provided by Law.

(j) Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the Parties shall use their reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the Parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

(k) Entire Agreement. This Agreement constitutes the entire agreement among the Parties with respect to the subject matter hereof and supersedes all prior contracts or agreements with respect to the subject matter hereof and the matters addressed or governed hereby, whether oral or written.

(l) Priority of Indemnification. Dynegy hereby acknowledges that each Holder Indemnified Person and Designated Director, and their respective heirs or representatives (each, an “ECP Indemnitee”), may have certain rights to indemnification, advancement of expenses and/or insurance provided by or on behalf of the Controlled Affiliates (collectively, the “Fund Indemnitors”) and that, notwithstanding anything to the contrary in this Agreement (including as set forth in Section 5 and Section 9(c)): (i) Dynegy is the indemnitor of first resort and the Fund Indemnitors are the indemnitors of last resort in connection with any claims for indemnification from the ECP Indemnitees, (ii) Dynegy will be required to advance the full amount of expenses incurred by each ECP Indemnitee and will be liable for the full amount of all losses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by Section 5 or Section 9(c), as applicable, without regard to any rights each ECP Indemnitee may have against the Fund Indemnitors, and (iii) the Parties irrevocably waive, relinquish and release the Fund Indemnitors from any and all claims against the Fund Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. Notwithstanding anything to the contrary in this Agreement, no advancement or payment by the Fund Indemnitors on behalf of an ECP Indemnitee with respect to any claim for which such ECP Indemnitee has sought indemnification or advancement of expenses from Dynegy will affect the foregoing and the Fund Indemnitors will have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of such ECP Indemnitee against Dynegy. The Fund Indemnitors are express third-party beneficiaries of the terms of this Section 14(l).

(m) No Recourse. Notwithstanding anything to the contrary that may be expressed or implied in this Agreement, any Delta Document or any other document or instrument delivered in connection herewith, and notwithstanding the fact that Purchaser or its Affiliates or any of its or their successors or permitted assignees may be a partnership or a limited liability company, Dynegy, by its acceptance of the benefits hereof, covenants, agrees and acknowledges that no Person other than Purchaser and, solely to the extent any Controlled Affiliate enters into a writing to be bound by the terms and conditions of this Agreement as contemplated by Section 7(d), such Controlled Affiliate, and its respective successors and permitted assignees shall have any obligation hereunder, and that it has no rights of recovery against, and no recourse hereunder, against, any former, current or future director, officer, agent,

advisor, attorney, Representative, Affiliate, manager or employee of Purchaser (or any of its successors or assignees), against any former, current or future general or limited partner, manager, member or stockholder of Purchaser, or any Affiliate thereof or against any former, current or future director, officer, agent, advisor, attorney, Representative, employee, Affiliate, assignee, general or limited partner, stockholder, manager or member of any of the foregoing (collectively, the “Non-Recourse Parties”), whether by or through attempted piercing of the corporate veil, by the enforcement of any judgment or assessment or by any legal or equitable Proceeding, or by virtue of any statute, regulation or other applicable Law, except that, notwithstanding the foregoing, nothing in this Section 14(m) shall limit Dynegy’s rights or remedies (i) under the Purchase Agreement, the Interim Sponsors Agreement or any Delta Document or (ii) under Section 14 to an injunction or injunctions against Purchaser, any Controlled Affiliate and any other Affiliate of Purchaser that is not an individual or limited partner to prevent breaches of this Agreement and to enforce specifically the performance of terms and provisions of this Agreement.
