To the extent any such lien and security interest is deemed to be granted pursuant to this Security Agreement in such Permitted Collateral hereunder notwithstanding the exclusion contemplated hereby, such lien and security interest shall ipso facto immediately and automatically terminate, without any further action by any Person, upon any such pledge, assignment, conveyance, transfer, grant of such right of set-off or grant of such Lien and security interest, provided, however, that any such Permitted Collateral shall cease to be excluded from this Section 2 at such time as (x) the Permitted Contract or Netting Agreement, as the case may be, related thereto is terminated and the setoff rights, Lien and security interest granted in such Permitted Collateral are terminated or (y) the applicable Grantor has obtained the consent of the applicable Counterparty to such Permitted Contracts or Netting Agreements to the assignment of, or creation of a lien and security interest in such Permitted Collateral hereunder (which consent such Grantor shall not be required to obtain hereunder, except upon a request of the Collateral Trustees after the occurrence and during the continuance of an Event of Default);

Dynegy Security Agreement

(v) as to each Grantor, (i) any outstanding voting stock of any entity that is a controlled foreign corporation under Section 957 of the Code (or any successor provision thereto), except for voting stock consisting of no more than 66% of the outstanding voting stock of such entity and (ii) any LS Operating Company Equity owned by such Grantor so long as (but only so long as) such LS Operating Company is an Unrestricted Subsidiary (any such stock being the “Excluded Equity”);

(vi) any property or accounts (including without limitation, coal, power, energy, other energy related products, natural gas, natural gas liquids, condensate, and sulfur, and including any other products resulting from generating, gas gathering, processing, fractionating and refining, marketed by any Grantor on behalf of third parties and the proceeds derived therefrom pursuant to processing agreements and/or marketing arrangements), to the extent (but only to the extent) that any Grantor manages, maintains or markets such property on behalf of a third party, including, without limitation, any Collateral maintained, managed or marketed by any Grantor for a joint venture in which third parties participate or on behalf of third parties;

(vii) any policy of insurance, provided, however, that proceeds of insurance shall be included as Collateral to the extent the security interest granted hereby in the goods covered by such insurance would continue in accordance with Section 9-315 of the UCC; and

(viii) the shares of stock or such other Equity Interests owned by and set forth opposite any relevant Grantor’s name on Schedule II-A hereto;

provided, however, that any proceeds received by any Grantor from the Disposition of Excluded Collateral, Excluded Authorizations, Excluded Equity and any other property excluded under clauses (i) through (viii) above shall constitute Collateral unless any assets or property constituting such proceeds are themselves subject to the exclusions set forth in clauses (i) through (viii) above.

Section 3. Security for Obligations. This Security Agreement secures, in the case of each Grantor, the payment of all Secured Obligations, whether direct or indirect, absolute or contingent, and whether for principal, reimbursement obligations, interest, fees, premiums, penalties, indemnifications, contract causes of action, costs, expenses or otherwise. Without limiting the generality of the foregoing, this Security Agreement secures, as to each Grantor, the payment of all amounts that constitute part of the Secured Obligations and would be owed by such Grantor to any Secured Party but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving a Loan Party.

Section 4. Grantors Remain Liable. Anything herein to the contrary notwithstanding, (a) each Grantor shall remain liable under the contracts and agreements included in such Grantor’s Collateral to the extent set forth therein to perform all of its duties and obligations thereunder to the same extent as if this Security Agreement had not been executed, (b) the exercise by the Collateral Trustees of any of the rights hereunder shall not release any Grantor from any of its duties or obligations under the contracts and agreements included in the

Dynegy Security Agreement

Collateral and (c) none of the Collateral Trustees, any Representative or any Secured Party shall have any obligation or liability under the contracts and agreements included in the Collateral by reason of this Security Agreement or any other Loan Document, nor shall any of the Collateral Trustees, any Representative or any Secured Party be obligated to perform any of the obligations or duties of any Grantor thereunder or to take any action to collect or enforce any claim for payment assigned hereunder or thereunder.

Section 5. Delivery and Control of Security Collateral. (a) With respect to any certificates or instruments representing or evidencing Security Collateral (other than instruments representing or evidencing Investments permitted by Section 7.02(b) of the Credit Agreement), to the extent that any relevant Grantor has Knowledge of the existence of such certificates and instruments, such certificates and instruments shall be delivered to and held by or on behalf of the Collateral Trustees pursuant to this Security Agreement and the Collateral Trust Agreement and shall be in suitable form for transfer by delivery, or shall be accompanied by duly executed instruments of transfer or assignment in blank, all in form and substance reasonably satisfactory to the Collateral Trustees. After the occurrence and during the continuance of an Event of Default, the Collateral Trustees shall have the right, at any time in their discretion and with notice to the Borrower, to transfer to or to register in the name of the Collateral Trustees or any of their nominees any or all of the Security Collateral, provided, however, that the failure to deliver any such notice to the Borrower shall not affect the validity of such actions of the Collateral Trustees. In addition, after the occurrence and during the continuance of an Event of Default, the Collateral Trustees shall have the right at any time to exchange certificates or instruments representing or evidencing Security Collateral for certificates or instruments of smaller or larger denominations.

(b) With respect to any Security Collateral in which any Grantor has any right, title or interest and that constitutes an uncertificated security, to the extent that such Grantor has Knowledge of the existence of such uncertificated securities, such Grantor will cause the issuer thereof either (at such Grantor’s election) (i) to register the Collateral Trustees as the registered owners of such security or (ii) to agree in an authenticated record with such Grantor and the Collateral Trustees that such issuer will comply with instructions with respect to such security originated by the Collateral Trustees without further consent of such Grantor, such authenticated record to be in form and substance reasonably satisfactory to the Collateral Trustees; provided, however, that the Collateral Trustees agree that they will not deliver any such instructions to such issuer except upon the occurrence and during the continuance of an Event of Default. With respect to any Security Collateral in which any Grantor has any right, title or interest and that is not an uncertificated security, upon the request of the Collateral Trustees after the occurrence and during the continuance of an Event of Default, such Grantor will notify each such issuer of Pledged Equity that such Pledged Equity is subject to the security interest granted hereunder.

(c) With respect to any Security Collateral in which any Grantor has any right, title or interest and that constitutes a security entitlement in which the Collateral Trustees are not the entitlement holder, to the extent that such Grantor has Knowledge of the existence of such security entitlements, such Grantor will cause the securities intermediary with respect to such security entitlement either (at such Grantor’s election) (i) to identify in its records the Collateral Trustees as the entitlement holders of such security entitlement against such securities intermediary or (ii) to agree in an authenticated record with such Grantor and the Collateral

Dynegy Security Agreement

Trustees that such securities intermediary will comply with entitlement orders (that is, notifications communicated to such securities intermediary directing transfer or redemption of the financial asset to which such Grantor has a security entitlement) originated by the Collateral Trustees without further consent of such Grantor, such authenticated record to be in substantially the form of Exhibit C hereto or otherwise in form and substance reasonably satisfactory to the Collateral Trustees (such agreement being a “Securities Account Control Agreement”).

(d) With respect to any Security Collateral in which any Grantor has any right, title or interest and that constitutes a commodity contract, to the extent that such Grantor has Knowledge of the existence of such commodity contracts, such Grantor shall cause the commodity intermediary with respect to such commodity contract to agree in an authenticated record with such Grantor and the Collateral Trustees that such commodity intermediary will apply any value distributed on account of such commodity contract as directed by the Collateral Trustees without further consent of such Grantor, such authenticated record to be in substantially the form of Exhibit D hereto or otherwise in form and substance reasonably satisfactory to the Collateral Trustees (such agreement being a “Commodity Account Control Agreement”, and all such authenticated records, together with all Securities Account Control Agreements being, collectively, “Security Control Agreements”).

(e) No Grantor will change or add any securities intermediary or commodity intermediary that maintains any securities account or commodity account in which any of the Collateral is credited or carried, or change or add any such securities account or commodity account, in each case without first complying with the above provisions of this Section 5 in order to perfect the security interest granted hereunder in such Collateral. For the avoidance of doubt, the provisions of this Section 5(e) shall not apply to any securities account or commodity account that any Grantor manages or maintains on behalf of third parties, such as securities accounts and commodity accounts maintained or managed by any Grantor for a joint venture in which third parties participate.

(f) Upon the request of the Collateral Trustees upon the occurrence and during the continuance of an Event of Default, such Grantor will notify each such issuer of Pledged Debt that such Pledged Debt is subject to the security interest granted hereunder.

(g) To the extent that any of the Collateral constituting money or any of the Account Collateral or any Security Collateral is subject to a Permitted Lien and such Permitted Lien has been perfected through control (as such term is used in Sections 9-104 and 9-106 of the UCC) or possession, perfection through possession or control of the security interest created hereunder shall not be required.

Section 6. Maintaining the Account Collateral. So long as any Secured Obligations (other than indemnification obligations that are not yet due and payable) which are accrued and payable shall remain unpaid and unsatisfied, or any Letter of Credit (with respect to which any reimbursement obligation related thereto constitutes a Secured Obligation) shall remain outstanding:

(a) Each Grantor will maintain all Designated Accounts only with the Collateral Trustees or with banks (the “Pledged Account Banks”) that have agreed, in a record

Dynegy Security Agreement

authenticated by the relevant Grantor, the Collateral Trustees and the Pledged Account Banks, to (i) comply with instructions originated by the Collateral Trustees (as set forth in the Account Control Agreement) directing the disposition of funds in the Designated Accounts without the further consent of the Grantor and (ii) waive or subordinate (other than as agreed between any Pledged Account Bank and the Collateral Trustees) in favor of the Collateral Trustees all claims of the Pledged Account Banks (including, without limitation, claims by way of a security interest, lien or right of setoff or right of recoupment) to the Account Collateral, which authenticated record shall be substantially in the form of Exhibit B hereto, or shall otherwise be in form and substance reasonably satisfactory to the Collateral Trustees (the “Account Control Agreement”); provided, however, that this Section 6(a) shall not apply to Other Deposit Accounts listed in Schedule V hereto, as such Schedule may be updated from time to time.

(b) Subject in all respects to the provisions of Section 5(g), each Grantor agrees that it will not add any bank that maintains a deposit account for such Grantor or open any new deposit account with any then existing Pledged Account Bank unless (i) the Collateral Trustees shall have received at least 10 days’ prior written notice of such additional bank or such new deposit account and (ii) the Collateral Trustees shall have received, in the case of a bank or Pledged Account Bank that is not the Collateral Trustees, an Account Control Agreement authenticated by such new bank and such Grantor, or a supplement to an existing Account Control Agreement with such then existing Pledged Account Bank, covering such new deposit account (and, upon the receipt by the Collateral Trustees of such Account Control Agreement or supplement, Schedule IV hereto shall be automatically amended to include such Other Deposit Account). Each Grantor may terminate any bank as a Pledged Account Bank or terminate any Designated Account, if it gives the Collateral Trustees at least 10 days’ prior written notice of such termination (and, upon such termination, Schedule IV hereto shall be automatically amended to delete such Pledged Account Bank and Other Deposit Account without any additional formal actions or agreements). For the avoidance of doubt, the provisions of this Section 6(b) shall not apply to any deposit account that any Grantor manages or maintains on behalf of third parties, such as deposit accounts maintained or managed by any Grantor for a joint venture in which third parties participate.

(c) Subject in all respects to the provisions of Section 5(g), upon any termination by a Grantor of any Other Deposit Account by such Grantor, or any Pledged Account Bank with respect thereto, such Grantor will promptly (i) either (at such Grantor’s election), (A) comply with the provisions regarding the opening of new deposit accounts as set forth in the first sentence of Section 6(b) or (B) subject to the restrictions set forth in Section 6(f), transfer all funds and property held in such terminated Other Deposit Account to another Other Deposit Account listed in Schedule IV and (ii) notify all Obligors that were making payments to such Other Deposit Account to make all future payments to another Other Deposit Account listed in Schedule IV hereto, in each case so that the Collateral Trustees shall have a continuously perfected security interest in such Designated Accounts. Subject in all respects to the provisions of Section 5(g), after the occurrence and during the continuance of an Event of Default, each Grantor agrees to terminate any or all Account Collateral and Account Control Agreements upon request by the Collateral Trustees.

Dynegy Security Agreement

(d) Upon the occurrence and during the continuance of a Collateral Trust Agreement Default, the Collateral Trustees shall have sole right to direct the disposition of funds with respect to each of the Designated Accounts.

(e) The Collateral Trustees may, at any time after notice to the Borrower (provided, however, that the failure to give any such notice to the Borrower shall not affect the validity of any action taken by the Collateral Trustees pursuant to the provisions of this Section 6(e)), but without consent from the Grantor, (i) transfer, or direct the transfer of, funds from the Designated Accounts to satisfy the Grantor’s obligations under the Secured Agreements if (i) (A) a payment default in respect of principal under such Secured Agreements shall have occurred and be continuing for a period greater than or equal to three Business Days, or (B) a payment default in respect of any amount other than principle due under such Secured Agreement shall have occurred and be continuing for a period greater than or equal to five Business Days, or (ii) an acceleration of the Facilities shall have occurred and be continuing.

(f) Each of the Grantors agrees that at no time shall the aggregate amount on deposit in the Other Deposit Accounts listed in Schedule V hereto (other than any Other Deposit Account that is subject to a Permitted Lien) exceed $20,000,000.

Section 7. Maintaining Electronic Chattel Paper, Transferable Records and Letter-of-Credit Rights and Giving Notice of Commercial Tort Claims. So long as any Secured Obligations (other than indemnification obligations that are not yet due and payable) which are accrued and payable shall remain unsatisfied, or any Letter of Credit (with respect to which any reimbursement obligation related thereto constitutes a Secured Obligation) shall remain outstanding:

(a) Each Grantor will maintain all (i) electronic chattel paper (to the extent that such Grantor has Knowledge of the existence of such electronic chattel paper) so that the Collateral Trustees have control of the electronic chattel paper in the manner specified in Section 9-105 of the UCC and (ii) all transferable records (to the extent that such Grantor has Knowledge of the existence of such transferable records) so that the Collateral Trustees have control of the transferable records in the manner specified in Section 16 of the UETA; and

(b) Each Grantor will immediately give notice to the Collateral Trustees of any material commercial tort claim that may arise in the future and will immediately execute or otherwise authenticate a supplement to this Security Agreement, and otherwise take all necessary action, to subject such material commercial tort claim to the first priority security interest, as applicable, created under this Security Agreement; provided, however, that any commercial tort claim shall not be covered by the provisions of this Section 7(b) to the extent, but only to the extent, that the assignment thereof or grant of a security interest therein would violate any effective or enforceable provision of applicable law.

Dynegy Security Agreement

Within the five years preceding the execution of this Security Agreement, the information set forth in Schedule I hereto with respect to such Grantor is true and accurate in all respects, except to the extent that failure of such information to be true and accurate could not reasonably be expected to result in a Material Adverse Effect. To the Knowledge of such Grantor, such Grantor has not previously changed its name, the location of its chief executive office, type of organization, jurisdiction of organization or organizational identification number (if such Grantor, now or has been organized in a jurisdiction that requires the organizational number of a debtor to be identified on the relevant financing statement in order to create a perfected first priority security interest) from those set forth in Schedule I hereto except as disclosed in Schedule III hereto.

(b) All Security Collateral consisting of certificated securities and instruments (other than those representing or evidencing Investments permitted by Section 7.02(b) of the Credit Agreement) have to the Knowledge of the relevant Grantor been delivered to the Collateral Trustees. To the Knowledge of the relevant Grantor, none of the Receivables or Agreement Collateral is evidenced by a promissory note or other instrument that has not been delivered to the Collateral Trustees.

(c) Such Grantor is the legal and beneficial owner of the Collateral of such Grantor free and clear of any Lien, claim, option or right of others, except for Permitted Liens or the security interest created under this Security Agreement. No effective financing statement or other instrument similar in effect covering all or any part of such Collateral or listing such Grantor or any trade name of such Grantor as debtor is on file in any recording office, except such as may have been filed in favor of the Collateral Trustees relating to the Secured Agreements or as otherwise permitted under the Credit Agreement.

(d) With respect to the Pledged Equity that is an uncertificated security, to the extent that such Grantor has Knowledge of the existence of any such uncertificated securities, such Grantor has caused the issuer thereof either (at such Grantor’s election) (i) to register the Collateral Trustees as the registered owners of such security or (ii) to agree in an authenticated record with such Grantor and the Collateral Trustees that such issuer will comply with instructions with respect to such security originated by the Collateral Trustees without further consent of such Grantor; provided, however, that the Collateral Trustees agree that they will not deliver any such instructions to such issuer except upon the occurrence and during the continuance of an Event of Default. If such Grantor is an issuer of Pledged Equity, such Grantor confirms that it has received notice of such security interest. With respect to all Security Collateral consisting of certificated securities and instruments, to the extent that the relevant Grantor has Knowledge of the existence of such certificated securities and instruments, all such certificated securities and instruments have been delivered to the Collateral Trustees.

Dynegy Security Agreement

(e) The Initial Pledged Equity pledged by such Grantor constitutes the percentage of the issued and outstanding Equity Interests of the issuers thereof indicated on Schedule II hereto.

(f) Subject in all respects to the provisions of Section 5(g), to the Knowledge of the relevant Grantor, such Grantor has no deposit accounts, other than the Account Collateral listed on Schedule IV hereto, as such Schedule IV may be amended from time to time pursuant to Section 6(b), and to the Knowledge of the relevant Grantor, legal, binding and enforceable Account Control Agreements are in effect for each deposit account that constitutes Account Collateral (other than Account Collateral consisting of deposit accounts maintained with the Collateral Trustees), except to the extent such Account Control Agreements are not required by Sections 5(g) or 6(a). For the avoidance of doubt, the representations and warranties in this Section 8(f) do not apply with respect to any deposit account that any Grantor manages or maintains on behalf of third parties, such as deposit accounts maintained or managed by any Grantor for a joint venture in which third parties participate.

(g) Subject in all respects to the provisions of Section 5(g), to the Knowledge of the relevant Grantor, all filings and other actions (including without limitation, (A) actions necessary to obtain control of Collateral as provided in Sections 9-104, 9-105 and 9-106 of the UCC and Section 16 of UETA and (B) actions necessary to perfect the Collateral Trustee’s security interest with respect to Collateral constituting certificated securities or instruments) necessary to perfect the security interest in the Collateral of such Grantor created under this Security Agreement have been duly made or taken and are in full force and effect, and this Security Agreement creates in favor of the Collateral Trustees for the benefit of the Secured Parties a valid and, together with such filings and other actions, perfected security interest in the Collateral of such Grantor, securing the payment of the Secured Obligations except, in each case, (i) as is otherwise permitted pursuant to the express provisions of this Security Agreement and (ii) for Permitted Liens.

(h) To the Knowledge of the relevant Grantor, Schedule VI is a complete and correct list of all commercial tort claims of each Grantor with a value exceeding $5,000,000.

Section 9. Further Assurances. (a) Each Grantor agrees that from time to time, at the expense of such Grantor, such Grantor will promptly execute and deliver, or otherwise authenticate, all further instruments and documents, and take all further action that (to the Knowledge of such Grantor) may be necessary, or that the Collateral Trustees reasonably may request, in order to perfect and protect any pledge, assignment or security interest granted or purported to be granted by such Grantor hereunder or to enable the Collateral Trustees to exercise and enforce their rights and remedies hereunder with respect to any Collateral of such Grantor. Without limiting the generality of the foregoing, each Grantor will promptly with respect to Collateral of such Grantor: (i) if any such Collateral shall be evidenced by a

Dynegy Security Agreement

promissory note or other instrument or chattel paper and if such Grantor has Knowledge of the existence of any such promissory notes, instruments, or chattel paper, deliver and pledge to the Collateral Trustees hereunder such note or instrument or chattel paper duly indorsed and accompanied by duly executed instruments of transfer or assignment, all in form and substance reasonably satisfactory to the Collateral Trustees; (ii) execute or authenticate and file such financing or continuation statements, or amendments thereto, and such other instruments or notices, as may be necessary, or as the Collateral Trustees reasonably may request, in order to perfect and preserve the security interest granted or purported to be granted by such Grantor hereunder; (iii) with respect to any certificates representing Security Collateral that constitutes certificated securities, to the extent that the relevant Grantor has Knowledge of the existence of such certificates, deliver and pledge to the Collateral Trustees for ratable benefit of the Representatives and the Secured Parties certificates representing Security Collateral that constitutes certificated securities, accompanied by undated stock or bond powers executed in blank; (iv) subject in all respects to the provisions of Section 5(g), with respect to any Collateral consisting of deposit accounts, electronic chattel paper, investment property or transferable records, to the extent that the relevant Grantor has Knowledge of the existence of such deposit accounts, electronic chattel paper, investment property or transferable records, take all action necessary to ensure that the Collateral Trustees have control of Collateral consisting of deposit accounts, electronic chattel paper, investment property and transferable records as provided in Sections 9-104, 9-105 and 9-106 of the UCC and in Section 16 of UETA; (v) upon the occurrence and during the continuance of an Event of Default, at the request of the Collateral Trustees, take all action to ensure that the Collateral Trustees’ security interest is noted on any certificate of title related to any Collateral evidenced by a certificate of title; and (vi) deliver to the Collateral Trustees evidence that all other action that the Collateral Trustees may deem reasonably necessary in order to perfect and protect the security interest created by such Grantor under this Security Agreement has been taken.

(b) Each Grantor hereby authorizes the Collateral Trustees to file one or more financing and continuation statements, and amendments thereto, relating to all or any part of the Collateral of such Grantor without the signature of such Grantor where permitted by law, which shall be filed by the Collateral Trustees upon the receipt of an instruction letter from the Required Representative requesting the taking of such action and attaching the form of financing statement. A photocopy or other reproduction of this Security Agreement or any financing statement covering the Collateral or any part thereof shall be sufficient as a financing statement where permitted by law. Each Grantor ratifies its authorization for the Collateral Trustees to have filed such financing statements, continuation statements or amendments filed prior to the date hereof.

(c) Each Grantor will furnish to the Collateral Trustees from time to time statements and schedules further identifying and describing the Collateral of such Grantor and such other reports in connection with such Collateral as the Collateral Trustees may reasonably request, all in reasonable detail.

Section 10. Post-Closing Changes; Bailees; Collections on Receivables and Related Contracts. (a) No Grantor will change its name, type of organization, jurisdiction of organization, organizational identification number (if such Grantor is organized in a jurisdiction that requires the organizational number of a debtor to be identified on a financing statement in

Dynegy Security Agreement

order to create a perfected first priority security interest) or location of its chief executive office (in the case only of a Grantor that is not a “registered organization”, as such term is defined in Section 9-102 of the UCC) from those set forth in Section 8(a) without first giving at least 30 days’ prior written notice to the Collateral Trustees and taking all action required by the Collateral Trustees for the purpose of perfecting or protecting the security interest granted by this Security Agreement. Except with respect to security agreements related to Permitted Liens, no Grantor will become bound by a security agreement authenticated by another Person (determined as provided in Section 9-203(d) of the UCC) without giving the Collateral Trustees 30 days’ prior written notice thereof and taking all action required by the Collateral Trustees to ensure that the perfection and first priority nature of the Collateral Trustees’ security interest in the Collateral will be maintained. If any Grantor that is organized in a jurisdiction that requires the organizational number of a debtor to be identified on a relevant financing statement in order to create a perfected first priority security interest does not have an organizational identification number and later obtains one, it will forthwith notify the Collateral Trustees of such organizational identification number.

(b) If any Collateral constituting goods of any Grantor is, to the Knowledge of such Grantor, at any time in the possession or control of a warehouseman, bailee or agent, or if the Collateral Trustees so requests such Grantor will (i) notify such warehouseman, bailee or agent of the security interest created hereunder, (ii) instruct such warehouseman, bailee or agent to hold all such Collateral solely for the Collateral Trustees’ account subject only to the Collateral Trustees’ instructions (which shall permit such Collateral to be removed by such Grantor in the ordinary course of business until the Collateral Trustees notifies such warehouseman, bailee or agent that an Event of Default has occurred and is continuing), (iii) use commercially reasonable efforts, to cause such warehouseman, bailee or agent to authenticate a record acknowledging that it holds possession of such Collateral for the Collateral Trustees’ benefit and shall act solely on the instructions of the Collateral Trustees without the further consent of the Grantor or any other Person; provided, however, that the Collateral Trustees agree that they will not deliver any such instructions to such issuer except upon the occurrence and during the continuance of an Event of Default, and (iv) make such authenticated record available to the Collateral Trustees.

(c) Except as otherwise provided in this subsection (c), each Grantor will continue to collect, at its own expense, all amounts due or to become due such Grantor under the Assigned Agreements, Receivables and Related Contracts. In connection with such collections, such Grantor may take (and, at the Collateral Trustees’ direction given after the occurrence and during the continuance of an Event of Default, will take) such action as such Grantor or the Collateral Trustees may deem necessary to enforce collection of the Assigned Agreements, Receivables and Related Contracts; provided, however, that the Collateral Trustees shall have the right at any time, upon the occurrence and during the continuance of an Event of Default and upon written notice to such Grantor of its intention to do so, to notify the Obligors under any Receivables and Related Contracts of the assignment of such Receivables and Related Contracts to the Collateral Trustees and to direct such Obligors to make payment of all amounts due or to become due to such Grantor thereunder directly to the Collateral Trustees and, upon such notification and at the expense of such Grantor, to enforce collection of any such Receivables and Related Contracts, to adjust, settle or compromise the amount or payment thereof, in the same manner and to the same extent as such Grantor might have done, and to otherwise exercise

Dynegy Security Agreement

all rights with respect to such Receivables and Related Contracts, including, without limitation, those set forth set forth in Section 9-607 of the UCC. After receipt by any Grantor of the notice from the Collateral Trustees referred to in the proviso to the preceding sentence, (i) all amounts and proceeds (including, without limitation, instruments) received by such Grantor in respect of the Receivables and Related Contracts of such Grantor shall be received in trust for the benefit of the Collateral Trustees hereunder, shall be segregated from other funds of such Grantor and shall be forthwith paid over to the Collateral Trustees in the same form as so received (with any necessary indorsement) to be applied as provided in the Collateral Trust Agreement and (ii) such Grantor will not adjust, settle or compromise the amount or payment of any Receivable or amount due on any Related Contract, release wholly or partly any Obligor thereof, or allow any credit or discount thereon except in the ordinary course of such Grantor’s business. For the avoidance of doubt, none of the provisions of this Section 10(c) shall apply with respect to any Property that is excluded from the lien and security interest granted hereunder pursuant to the provisions of clauses (i), (ii), (iii), (iv), (v), (vi), (vii) or (viii) of the “notwithstanding” clause at the end of Section 2, including, but not limited to, Excluded Collateral, Excluded Authorizations, Permitted Collateral or Excluded Equity.

Section 11. As to Intellectual Property Collateral. (a) With respect to its material Intellectual Property Collateral, each Grantor agrees, upon the request of the Collateral Trustees, to execute or otherwise authenticate an agreement in substantially the form set forth in Exhibit E hereto or otherwise in form and substance reasonably satisfactory to the Collateral Trustees (an “Intellectual Property Security Agreement”), for recording the security interest granted hereunder to the Collateral Trustees in such Intellectual Property Collateral with the U.S. Patent and Trademark Office, the U.S. Copyright Office and any other governmental authorities necessary to perfect the security interest hereunder in such material Intellectual Property Collateral.

(b) Each Grantor agrees that should it obtain an ownership interest in any item of the type set forth in Section 2(g) that is not on the date hereof a part of the Intellectual Property Collateral (“After-Acquired Intellectual Property”) (i) the provisions of this Security Agreement shall automatically apply thereto, and (ii) any such After-Acquired Intellectual Property and, in the case of trademarks, the goodwill symbolized thereby, shall automatically become part of the Intellectual Property Collateral subject to the terms and conditions of this Security Agreement with respect thereto. At the end of each fiscal quarter of the Borrower, each Grantor shall give written notice to the Collateral Trustees identifying any material After-Acquired Intellectual Property acquired during such fiscal quarter, and upon the request of the Collateral Trustees, such Grantor shall execute and deliver to the Collateral Trustees with such written notice, or otherwise authenticate, an agreement substantially in the form of Exhibit F hereto or otherwise in form and substance reasonably satisfactory to the Collateral Trustees (an “IP Security Agreement Supplement”) covering such material After-Acquired Intellectual Property which IP Security Agreement Supplement shall be recorded with the U.S. Patent and Trademark Office, the U.S. Copyright Office and any other governmental authorities necessary to perfect the security interest hereunder in such material After-Acquired Intellectual Property.

(i) Each Grantor shall be entitled to exercise any and all voting and other consensual rights pertaining to the Security Collateral of such Grantor or any part thereof for any purpose; provided however, that such Grantor will not exercise or refrain from exercising any such right if such action could reasonably be expected to result in a Material Adverse Effect.

(ii) Each Grantor shall be entitled to receive and retain any and all dividends, interest and other distributions paid in respect of the Security Collateral of such Grantor if and to the extent that the payment thereof is not otherwise prohibited by the terms of the Secured Agreements; provided, however, that any and all dividends, interest and other distributions paid or payable other than in cash in respect of, and instruments and other property received, receivable or otherwise distributed in respect of, or in exchange for, any Security Collateral shall be, and shall be forthwith delivered to the Collateral Trustees to hold as, Security Collateral and shall, if received by such Grantor, be received in trust for the benefit of the Collateral Trustees, be segregated from the other property or funds of such Grantor and be forthwith delivered to the Collateral Trustees as Security Collateral in the same form as so received (with any necessary indorsement).

(iii) The Collateral Trustees will execute and deliver (or cause to be executed and delivered) to each Grantor all such proxies and other instruments as such Grantor may reasonably request for the purpose of enabling such Grantor to exercise the voting and other rights that it is entitled to exercise pursuant to paragraph (i) above and to receive the dividends or interest payments that it is authorized to receive and retain pursuant to paragraph (ii) above.

(b) Upon the occurrence and during the continuance of an Event of Default and notice to the Borrower (provided that the failure to give any such notice shall not affect the validity of any of the following actions taken by the Collateral Trustees):

(i) All rights of each Grantor (x) to exercise or refrain from exercising the voting and other consensual rights that it would otherwise be entitled to exercise pursuant to Section 12(a)(i) shall, upon notice to such Grantor by the Collateral Trustees, cease and (y) to receive the dividends, interest and other distributions that it would otherwise be authorized to receive and retain pursuant to Section 12(a)(ii) shall automatically cease, and all such rights shall thereupon become vested in the Collateral Trustees, who shall thereupon have the sole right to exercise or refrain from exercising such voting and other consensual rights and to receive and hold as Security Collateral such dividends, interest and other distributions.

(ii) All dividends, interest and other distributions that are received by any Grantor contrary to the provisions of paragraph (i) of this Section 12(b) shall be received in trust for the benefit of the Collateral Trustees, shall be segregated from other funds of such Grantor and shall be forthwith paid over to the Collateral Trustees as Security Collateral in the same form as so received (with any necessary indorsement).

(iii) The Collateral Trustees shall be authorized to send to each Securities Intermediary or Commodity Intermediary as defined in and under any Security Control Agreement a Notice of Exclusive Control as defined in and under such Security Control Agreement.

Section 13. As to Letter-of-Credit Rights. (a) Each Grantor, by granting a security interest in its Receivables consisting of letter-of-credit rights to the Collateral Trustees, intends to (and hereby does) assign to the Collateral Trustees its rights (including its contingent rights) to the proceeds of all Related Contracts consisting of letters of credit of which it is or hereafter becomes a beneficiary or assignee. Upon the request of the Collateral Trustees after the occurrence and during the continuance of an Event of Default, each Grantor will promptly use its commercially reasonable efforts to cause the issuer of each letter of credit and each nominated person (if any) with respect thereto to consent to such assignment of the proceeds thereof in a Consent to Assignment of Letter of Credit Rights.

(b) Upon the occurrence and during the continuance of an Event of Default, each Grantor will, promptly upon request by the Collateral Trustees, (i) notify (and such Grantor hereby authorizes the Collateral Trustees to notify) the issuer and each nominated person with respect to each of the Related Contracts consisting of letters of credit that the proceeds thereof have been assigned to the Collateral Trustees hereunder and any payments due or to become due in respect thereof are to be made directly to the Collateral Trustees or their designee.

(c) With respect to any Securities Account Control Agreement, Commodity Accounts Control Agreement, Account Control Agreement or Consent to Assignment of Letter of Credit Rights, the Collateral Trustees agree that they will not issue any entitlement orders or other directions, instructions or notifications thereunder with respect to the disposition or transfer of any Collateral therein addressed or blocking any Grantor’s ability to deal with any such Collateral, except upon the occurrence and during the continuance of a Collateral Trust Agreement Default. The Collateral Trustees further agree that, upon their issuance of any such entitlement orders, directions, instructions or notifications, they will promptly provide a copy thereof to the relevant Grantor.

Section 14. Transfers and Other Liens; Additional Shares. (a) Each Grantor agrees that it will not (i) sell, assign or otherwise dispose of, or grant any option with respect to, any of the Collateral, other than sales, assignments and other dispositions of Collateral, and options relating to Collateral, permitted under the terms of the Credit Agreement, or (ii) create or suffer to exist any Lien upon or with respect to any of the Collateral of such Grantor except for the pledge, assignment and security interest created under this Security Agreement and Liens permitted under the Credit Agreement.

(b) Each Grantor agrees that it will pledge hereunder, promptly upon its acquisition (directly or indirectly) thereof, any and all additional Equity Interests or other securities that are issued by any Grantor and are Pledged Equity.

Section 15. Collateral Trustees Appointed Attorneys-in-Fact. Each Grantor hereby irrevocably appoints the Collateral Trustees such Grantor’s attorneys-in-fact, with full authority in the place and stead of such Grantor and in the name of such Grantor or otherwise, from time to time, upon the occurrence and during the continuance of an Event of Default, in the Collateral Trustees’ discretion, to take any action and to execute any instrument that the Collateral Trustees may deem necessary or advisable to accomplish the purposes of this Security Agreement, including, without limitation:

Dynegy Security Agreement

(a) to obtain and adjust insurance required to be paid to the Collateral Trustees pursuant to the provisions of the Credit Agreement,

(b) to ask for, demand, collect, xxx for, recover, compromise, receive and give acquittance and receipts for moneys due and to become due under or in respect of any of the Collateral,

(c) to receive, indorse and collect any drafts or other instruments, documents and chattel paper, in connection with clause (a) or (b) above, and

(d) to file any claims or take any action or institute any proceedings that the Collateral Trustees may deem necessary or desirable for the collection of any of the Collateral or otherwise to enforce compliance with the terms and conditions of any Assigned Agreement or the rights of the Collateral Trustees with respect to any of the Collateral.

Section 16. Collateral Trustees May Perform. If any Grantor fails to perform any agreement contained herein, the Collateral Trustees may, but without any obligation to do so and without notice, themselves perform, or cause performance of, such agreement, and the expenses of the Collateral Trustees incurred in connection therewith shall be payable by such Grantor under Section 19.

Section 17. The Collateral Trustees’ Duties. (a) The powers conferred on the Collateral Trustees hereunder are solely to protect the Secured Parties’ interest in the Collateral and shall not impose any duty upon them to exercise any such powers. Except for the safe custody of any Collateral in their possession and the accounting for moneys actually received by them hereunder, the Collateral Trustees shall have no duty as to any Collateral, as to ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Collateral, whether or not any Secured Party has or is deemed to have knowledge of such matters, or as to the taking of any necessary steps to preserve rights against any parties or any other rights pertaining to any Collateral. The Collateral Trustees shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in their possession if such Collateral is accorded treatment substantially equal to that which they accord their own property.

(b) Anything contained herein to the contrary notwithstanding, the Collateral Trustees may from time to time, when the Collateral Trustees deem it to be necessary, appoint one or more subagents (each a “Subagent”) for the Collateral Trustees hereunder with respect to all or any part of the Collateral. Without limiting the foregoing, the Collateral Trustees hereby appoint JPMorgan Chase Bank, N.A., as Collateral Agent under the Credit Agreement, as Subagent with respect to the Term L/C Collateral Account and any Cash Collateral Account referred to in Section 2.03(g) of the Credit Agreement. In the event that the Collateral Trustees so appoint any Subagent with respect to any Collateral, (i) the assignment and pledge of such Collateral and the security interest granted in such Collateral by each Grantor hereunder shall be

Dynegy Security Agreement

deemed for purposes of this Security Agreement to have been made to such Subagent, in addition to the Collateral Trustees, for the ratable benefit of the Secured Parties, as security for the Secured Obligations of such Grantor, (ii) such Subagent shall automatically be vested, in addition to the Collateral Trustees, with all rights, powers, privileges, interests and remedies of the Collateral Trustees hereunder with respect to such Collateral, and (iii) the term “Collateral Trustees,” when used herein in relation to any rights, powers, privileges, interests and remedies of the Collateral Trustees with respect to such Collateral, shall include such Subagent; provided, however, that no such Subagent shall be authorized to take any action with respect to any such Collateral unless and except to the extent expressly authorized in the Credit Agreement or writing by the Collateral Trustees.

Section 18. Remedies. If any Event of Default shall have occurred and be continuing:

(a) The Collateral Trustees may with the consent of the Required Representative and shall at the request of the Required Representative exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party upon default under the UCC (whether or not the UCC applies to the affected Collateral) and also may: (i) require each Grantor to, and each Grantor hereby agrees that it will at its expense and upon request of the Collateral Trustees forthwith, assemble all or part of the Collateral as directed by the Collateral Trustees and make it available to the Collateral Trustees at a place and time to be designated by the Collateral Trustees that is reasonably convenient to all parties; (ii) without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any of the Collateral Trustees’ offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Collateral Trustees may deem commercially reasonable; (iii) to the fullest extent permitted by applicable law and by contracts with third parties, and subject to any applicable safety requirements at any such premises, occupy any premises owned or leased by any of the Grantors where the Collateral or any part thereof is assembled or located for a reasonable period in order to effectuate their rights and remedies hereunder or under law, without obligation to such Grantor in respect of such occupation; and (iv) exercise any and all rights and remedies of any of the Grantors under or in connection with the Collateral, or otherwise in respect of the Collateral, including, without limitation, (A) any and all rights of such Grantor to demand or otherwise require payment of any amount under, or performance of any provision of, the Assigned Agreements, the Receivables, the Related Contracts and the other Collateral, (B) withdraw, or cause or direct the withdrawal of all funds with respect to the Account Collateral and (C) exercise all other rights and remedies with respect to the Assigned Agreements, the Receivables, the Related Contracts and the other Collateral, including, without limitation, those set forth in Section 9-607 of the UCC. Each Grantor agrees that, to the extent notice of sale shall be required by law, at least ten days’ notice to such Grantor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Collateral Trustees shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Collateral Trustees may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned.

Dynegy Security Agreement

(b) Any cash held by or on behalf of the Collateral Trustees and all cash proceeds received by or on behalf of the Collateral Trustees in respect of any sale of, collection from, or other realization upon all or any part of the Collateral may, in the discretion of the Collateral Trustees, be held by the Collateral Trustees as collateral for, and/or then or at any time thereafter applied (after payment of any amounts payable to the Collateral Trustees pursuant to Section 19) in whole or in part by the Collateral Trustees for the ratable benefit of the Representatives and the Secured Parties against, all or any part of the Secured Obligations, in accordance with the terms of the Collateral Trust Agreement.

(c) All payments received by any Grantor under or in connection with any Assigned Agreement or otherwise in respect of the Collateral shall be received in trust for the benefit of the Collateral Trustees, shall be segregated from other funds of such Grantor and shall be forthwith paid over to the Collateral Trustees in the same form as so received (with any necessary endorsement).

(d) The Collateral Trustees may, without notice to any Grantor except as required by law and at any time or from time to time, charge, set-off and otherwise apply all or any part of the Secured Obligations against any funds held with respect to the Account Collateral or in any other deposit account.

(e) In the event of any sale or other disposition of any of the Intellectual Property Collateral of any Grantor, the goodwill symbolized by any Trademarks subject to such sale or other disposition shall be included therein, and such Grantor shall supply to the Collateral Trustees or their designee such Grantor’s know-how and expertise, and documents and things relating to any Intellectual Property Collateral subject to such sale or other disposition, and such Grantor’s customer lists and other records and documents relating to such Intellectual Property Collateral and to the manufacture, distribution, advertising and sale of products and services of such Grantor.

Section 19. Indemnity and Expenses. (a) Each Grantor agrees to indemnify, defend and save and hold harmless the Collateral Trustees, each Representative and each Secured Party and each of their Affiliates and their respective officers, directors, employees, agents and advisors (each, an “Indemnified Party”) from and against, and shall pay on demand, any and all claims, damages, losses, liabilities and expenses (including, without limitation, reasonable fees and expenses of counsel) that may be incurred by or asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or resulting from this Security Agreement (including, without limitation, enforcement of this Security Agreement), except to the extent such claim, damage, loss, liability or expense is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Party’s gross negligence or willful misconduct. The provisions of this Section 19(a) shall survive the termination of this Security Agreement.

Dynegy Security Agreement

(b) Each Grantor will upon demand pay to the Collateral Trustees the amount of any and all reasonable expenses, including, without limitation, the reasonable fees and expenses of their counsel and of any experts and agents, that the Collateral Trustees may incur in connection with (i) the administration of this Security Agreement, (ii) the custody, preservation, use or operation of, or the sale of, collection from or other realization upon, any of the Collateral of such Grantor, (iii) the exercise or enforcement of any of the rights of the Collateral Trustees, the Representatives or the other Secured Parties hereunder or (iv) the failure by such Grantor to perform or observe any of the provisions hereof.

(c) EACH GRANTOR ACKNOWLEDGES THAT THIS SECURITY AGREEMENT AND OTHER TRANSACTION DOCUMENTS CONTAIN PROVISIONS RELEASING EACH INDEMNIFIED PARTY FROM LIABILITY AND/OR INDEMNIFYING AND HOLDING HARMLESS EACH INDEMNIFIED PARTY FOR, AMONG OTHER THINGS, SUCH INDEMNIFIED PARTY’S OWN NEGLIGENCE. EACH GRANTOR AGREES THAT THE RELEASE AND/OR INDEMNITY PROVISIONS CONTAINED IN THESE DOCUMENTS ARE CAPTIONED TO CLEARLY IDENTIFY THE RELEASE AND/OR INDEMNITY PROVISIONS AND, THEREFORE, ARE SO CONSPICUOUS THAT EACH GRANTOR HAS FAIR NOTICE OF THE EXISTENCE AND CONTENTS OF SUCH PROVISIONS. EACH GRANTOR HEREBY WAIVES ANY DEFENSES IT MIGHT ASSERT AGAINST EACH INDEMNIFIED PARTY BASED ON THE HOLDING OF THE TEXAS SUPREME COURT IN ETHYL CORP. x. XXXXXX CONST. CO., 725 S.W.2d 705 (Tex. 1987), PAGE PETROLEUM, INC., et al. V. DRESSER INDUSTRIES, INC., et al., 853 S.W.2d 505 (Tex. 1993), AND QUORUM HEALTH RESOURCES, L.L.C. v. MAVERICK COUNTY HOSPITAL DISTRICT et al., 308 F.3rd 451 (5th Cir. 2002) AND ANY RELATED CASE LAW HOLDINGS.

Section 20. Amendments; Waivers; Additional Grantors; Etc. (a) No amendment or waiver of any provision of this Security Agreement, and no consent to any departure by any Grantor herefrom, shall in any event be effective unless the same shall be in writing and signed by the Collateral Trustees and the Borrower and otherwise shall comply with the provisions of Section 9.01 of the Collateral Trust Agreement, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No failure on the part of the Collateral Trustees, the Representatives or any other Secured Party to exercise, and no delay in exercising any right hereunder, shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right.

(b) Upon the execution and delivery, or authentication, by any Person of a security agreement supplement in substantially the form of Exhibit A hereto (each a “Security Agreement Supplement”), (i) such Person shall be referred to as an “Additional Grantor” and shall be and become a Grantor hereunder, and each reference in this Security Agreement and the other Secured Agreements to “Grantor” shall also mean and be a reference to such Additional Grantor, and each reference in this Security Agreement and the other Secured Agreements to “Collateral” shall also mean and be a reference to the Collateral of such Additional Grantor, and (ii) the supplemental schedules I-VI attached to each Security Agreement Supplement shall be incorporated into and become a part of and supplement Schedules I-VI, respectively, hereto, and the Collateral Trustees may attach such supplemental schedules to such Schedules; and each reference to such Schedules shall mean and be a reference to such Schedules as supplemented pursuant to each Security Agreement Supplement.

Dynegy Security Agreement

In no event shall a voicemail message be effective as a notice, communication or confirmation hereunder.

(b) Any amendment or waiver of any provision of this Security Agreement or of any Security Agreement Supplement or Schedule hereto may be transmitted and/or signed by facsimile. The effectiveness of any such documents and signatures shall, subject to applicable Law, have the same force and effect as manually signed originals and shall be binding on all parties thereto. The Collateral Trustees may also require that any such documents and signatures be confirmed by a manually signed original thereof; provided, however, that the failure to request or deliver the same shall not limit the effectiveness of any facsimile document or signature.

(c) Electronic mail and Internet and intranet websites may be used only to distribute routine communications and to distribute Collateral Documents for execution by the parties thereto, and may not be used for any other purpose.

(e) any change, restructuring or termination of the corporate structure or existence of any Loan Party or any of its Subsidiaries;

(f) any failure of any Secured Party to disclose to any Loan Party any information relating to the business, condition (financial or otherwise), operations, performance, assets, nature of assets, liabilities or prospects of any other Loan Party now or hereafter known to such Secured Party (each Grantor waiving any duty on the part of the Secured Parties to disclose such information);

(g) the failure of any other Person to execute this Security Agreement or any other Collateral Document, guaranty or agreement or the release or reduction of liability of any Grantor or other grantor or surety with respect to the Secured Obligations; or

To the fullest extent permitted under applicable law, this Security Agreement shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Secured Obligations is rescinded or must otherwise be returned by the Collateral Trustees, any Representative or any Secured Party or by any other Person upon the insolvency, bankruptcy or reorganization of any Loan Party or otherwise, all as though such payment had not been made.

Section 25. Execution in Counterparts. This Security Agreement may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Security Agreement by telecopier shall be effective as delivery of an original executed counterpart of this Security Agreement.

Section 26. The Mortgages.

Dynegy Security Agreement

Section 27. Collateral in the State of Louisiana. (a) As to all Collateral now or hereafter located in the State of Louisiana, or as to which the laws of the State of Louisiana may now be or hereafter become applicable, each Grantor hereby acknowledges the Secured Obligations, whether now existing or to arise hereafter, and confesses judgment thereon if the Secured Obligations are not paid at maturity, and does by these presents consent, agree and stipulate that if any portion of the Secured Obligations is not promptly and fully paid when due, the Secured Obligations shall, at the option of the Collateral Trustees, become immediately due and payable and it shall be lawful for the Collateral Trustees, without making a demand and without notice or putting in default, the same being hereby expressly waived, to cause all and singular the Collateral to be seized and sold by executory process, without appraisement (appraisement being hereby expressly waived), either in its entirety or in lots or parcels, as the Collateral Trustees may determine, to the highest bidder for cash, or on such terms as plaintiff in such proceedings may direct.

(c) Each Grantor acknowledges that the Collateral Trustees shall have all rights to appointment of a keeper in connection with any action to foreclose the lien hereof, all in accordance with La. R.S. 9:5136 et seq. The Court before which the proceedings are pending shall determine the keeper’s fees, and the payment of such fees shall constitute a portion of the Secured Obligations secured by the lien hereof.

(d) This Section 27 shall in no way affect or be deemed a waiver of the provisions of Section 28 or Section 29.

Section 28. Governing Law. This Security Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

Section 29. Submission to Jurisdiction and Waiver. (a) Each Grantor hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any New York State court or federal court of the United States sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Security Agreement and the other Loan Documents to which it is or is to be a party, or for recognition or enforcement of any judgment, and each Grantor hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in any such New York State court or, to the extent permitted by law, in such federal court. Each Grantor agrees that a final judgment in any such action or proceeding

Dynegy Security Agreement

shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Security Agreement shall affect any right that any party may otherwise have to bring any action or proceeding relating to this Security Agreement in the courts of any jurisdiction.

(b) Each Grantor irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Security Agreement to which it is or is to be a party in any New York State or federal court. Each Grantor hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such suit, action or proceeding in any such court.

(c) EACH GRANTOR HEREBY KNOWINGLY, INTENTIONALLY AND VOLUNTARILY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS SECURITY AGREEMENT, THE LOANS OR THE ACTIONS OF ANY BANKS IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT THEREOF.

Section 30. Certification. Pursuant to Section 9.01(b) of the Collateral Trust Agreement, each Representative (as defined in the Collateral Trust Agreement) hereby certifies to the Required Representative (as defined in the Collateral Trust Agreement) that this Security Agreement complies with the amendment provisions of the Existing Shared Security Agreement and the Existing Non-Shared Security Agreement.

SECTION 3. Grantor’s Rights in Accounts. (a) Except as otherwise provided in this Section 3, the Account Holder will comply with Account Directions and other directions concerning each Account originated by the Grantor without further consent by the Secured Party.

SECTION 5. Statements, Confirmations, and Notices of Adverse Claims. (a) The Account Holder will send copies of all statements and confirmations for each Account simultaneously to the Secured Party and the Grantor.

SECTION 6. The Account Holder’s Responsibility. (a) Except for permitting a withdrawal, delivery, or payment in violation of Section 3, the Account Holder will not be liable to the Secured Party for complying with Account Directions or other directions concerning any Account from the Grantor that are received by the Account Holder before the Account Holder receives and has a reasonable opportunity to act on a Notice of Exclusive Control.

(b) The Account Holder will not be liable to the Grantor or the Secured Party for complying with a Notice of Exclusive Control or with an Account Direction or other direction concerning any Account originated by the Secured Party, even if the Grantor notifies the Account Holder that the Secured Party is not legally entitled to issue the Notice of Exclusive Control or Account Direction or such other direction unless the Account Holder takes the action after it is served with an injunction, restraining order, or other legal process enjoining it from doing so, issued by a court of competent jurisdiction, and had a reasonable opportunity to act on the injunction, restraining order or other legal process.

Uniform Commercial Code and, in the case of any Account that is a deposit account, in Article 4 of the N.Y. Uniform Commercial Code. In particular, the Account Holder need not investigate whether the Secured Party is entitled under the Secured Party’s agreements with the Grantor to give an Account Direction or other direction concerning any Account or a Notice of Exclusive Control. The Account Holder may rely on notices and communications it believes given by the appropriate party.

The Grantor will indemnify the Account Holder, its officers, directors, employees and agents against claims, liabilities and expenses arising out of this Agreement (including, without limitation, reasonable attorney’s fees and disbursements), except to the extent the claims, liabilities or expenses are caused by the Account Holder’s gross negligence or willful misconduct as found by a court of competent jurisdiction in a final, non-appealable judgment.

(a) The Commodity Intermediary will not be liable to the Secured Party for complying with Entitlement Orders or other directions concerning the Account from the Grantor that are received by the Commodity Intermediary before the Commodity Intermediary receives and has a reasonable opportunity to act on a Notice of Exclusive Control.

(b) The Commodity Intermediary will not be liable to the Grantor for complying with a Notice of Exclusive Control or with an Entitlement Order or other direction concerning the Account originated by the Secured Party, even if the Grantor notifies the Commodity Intermediary that the Secured Party is not legally entitled to issue the Notice of Exclusive Control or Entitlement Order or such other direction unless the Commodity Intermediary takes the action after it is served with an injunction, restraining order, or other legal process enjoining it from doing so, issued by a court of competent jurisdiction, and had a reasonable opportunity to act on the injunction, restraining order or other legal process.
