Indemnification Agreements

ENLC has a practice of entering into indemnification agreements (the “Indemnification Agreements”) with each of the Manager’s directors and executive officers (collectively, the “Indemnitees”). In connection with the appointment of the New Directors to the Manager Board, ENLC entered into an Indemnification Agreement with each of the New Directors. Under the terms of the Indemnification Agreements, ENLC has agreed to indemnify and hold the Indemnitees harmless, subject to certain conditions, from and against any and all losses, claims, damages, liabilities, judgments, fines, taxes (including ERISA excise taxes), penalties (whether civil, criminal, or other), interest, assessments, amounts paid or payable in settlements, or other amounts and any and all “expenses” (as defined in the Indemnification Agreements) arising from any and all threatened, pending, or completed claims, demands, actions, suits, proceedings, or alternative dispute mechanisms, whether civil, criminal, administrative, arbitrative, investigative, or otherwise, whether made pursuant to federal, state, or local law, whether formal or informal, and including appeals (each, a “proceeding”), in each case, in which the Indemnitee may be involved, or is threatened to be involved, as a party, a witness, or otherwise, including any inquiries, hearings, or investigations that the Indemnitee determines might lead to the institution of any proceeding, related to the fact that the Indemnitee is or was a director, manager, or officer of ENLC or the Manager, or is or was serving at the request of ENLC or the Manager, each as applicable, as a manager, managing member, general partner, director, officer, fiduciary, trustee, or agent of any other entity, organization, or person of any nature. ENLC has also agreed to advance the expenses of an Indemnitee relating to the foregoing. To the extent that a change in the laws of the State of Delaware permits greater indemnification under any statute, agreement, organizational document, or governing document than would be afforded under the Indemnification Agreements as of the date of the Indemnification Agreements, the Indemnitee shall enjoy the greater benefits so afforded by such change.
