on the operations of the Indemnified Party and further agrees to maintain the confidentiality of all files, records and other information furnished by the Indemnified Party pursuant to this Section 2.6. In no event will the obligation of the Indemnified Party to cooperate with the Indemnifying Party as set forth in the immediately preceding sentence be construed as imposing upon the Indemnified Party an obligation to hire and pay for counsel in connection with the defense of any claims covered by the indemnification set forth in this Article II; provided, however, that the Indemnified Party may, at its own option, cost and expense, hire and pay for counsel in connection with any such defense. The Indemnifying Party agrees to keep any such counsel hired by the Indemnified Party informed as to the status of any such defense, but the Indemnifying Party will have the right to retain sole control over such defense.

With respect to any such consolidated, combined or unitary income, franchise or similar tax return, the amount of the Partnership Group’s reimbursement to CEG will be equal to the tax that those Partnership Group Members included with CEG on such tax return would have paid had such Partnership Group Members not been included on such return. Any reimbursement payment required under this provision will be due within 45 days after CEG makes the tax payment giving rise to such reimbursement.

Section 3.4 Limitation of Duties and Liability. The relationship of CEG to the Partnership Entities pursuant to this Article III is as an independent contractor and nothing in this Agreement will be construed to impose on CEG, or on any of its Affiliates, or on any of its respective successor and permitted assigns, or on its respective employees, officers, members, managers, directors, agents and representatives, any express or implied fiduciary duty. CEG and its Affiliates and its respective successor and permitted assigns, together with their respective employees, officers, members, managers, directors, agents and representatives, will not be liable for, and the Partnership Entities will not take, or permit to be taken, any action against any of such Persons to hold such Persons liable for (a) any error of judgment or mistake of law by such Persons or for any Loss suffered by such Persons in connection with the performance of any Services under this Agreement, except for a liability or loss resulting from gross negligence, willful misconduct, bad faith or reckless disregard in the performance by such Persons of the Services, or (b) any fraudulent or dishonest acts by the Partnership Entities. In no event, whether based on contract, indemnity, warranty, tort (including negligence), strict liability or otherwise, will CEG or its Affiliates, its respective successor and permitted assigns, or its respective employees, officers, members, managers, directors, agents and representatives, be liable for loss of profits or revenue or special, incidental, exemplary, punitive or consequential damages.

ARTICLE IV

RIGHT OF FIRST OFFER

Section 4.1 Right of First Offer to Purchase Certain Interest.

(a) CEG hereby grants to the MLP a right of first offer on any proposed Transfer of equity interests in OpCo specifying the fundamental terms of the proposed Transfer, other than the sale price. The Parties acknowledge that the MLP is not obligated to purchase any additional interest in OpCo from CEG.

(b) The Parties acknowledge that all potential Transfers of equity interest pursuant to this Section 4.1 are subject to obtaining any and all required written consents of Governmental Authorities and other non-affiliated third parties (including, without limitation, Lenders and other providers of financing) and to the terms of all agreements (including, without limitation, debt and other financing arrangements) in respect of such equity interest in OpCo.

Section 4.2 Procedures.

(a) If CEG proposes to Transfer any equity interests in CPG OpCo LP, a Delaware limited partnership (“OpCo”), with respect to which a right of first offer has been granted pursuant to this Article IV to any Person pursuant to a bona fide third-party offer (an “Acquisition Proposal”), then CEG, bound by such right of first offer, will promptly give written notice (a “Disposition Notice”) thereof to the Partnership Group. The Disposition Notice will set forth the following information in respect of the proposed Transfer: the name and address of the prospective acquiror (the “Proposed Transferee”), the equity interest subject to the Acquisition Proposal (the “OpCo Interest”), the purchase price offered by such Proposed Transferee (the “Offer Price”), reasonable detail concerning any non-cash portion of the proposed consideration, if any, to allow the MLP to reasonably determine the fair market value of such non-cash consideration, CEG’s estimate of the fair market value of any non-cash consideration and all other material terms and conditions of the Acquisition Proposal that are then known to CEG. To the extent the Proposed Transferee’s offer consists of consideration other than cash (or in addition to cash), the Offer Price will be deemed equal to the amount of any such cash plus the fair market value of such non-cash consideration. In the event CEG and the MLP agree as to the fair market value of any non-cash consideration, the Conflicts Committee will provide written notice of its decision regarding the exercise of its right of first offer to purchase the OpCo Interest within 45 days of its receipt of the Disposition Notice. Thereafter, the Conflicts Committee and CEG will enter into good faith negotiations for a 45-day period to reach an agreement to purchase the OpCo Interest. If the Conflicts Committee and CEG are unable to agree on the terms of purchase for the OpCo Interest after negotiating in good faith for the 45-day period, CEG may provide notice that it rejects the Conflicts Committee’s offer and will seek an alternative bona fide third-party offer. In the event CEG is able to obtain a good faith, binding offer to pay at least 105% of the highest purchase price (on a present value basis) proposed or as contained in any greater written offer made by the Conflicts Committee during the 45-day negotiation period, then CEG may sell the OpCo Interest at such greater price to a third party. If an alternative transaction complying with the provisions set out immediately above has not been consummated by CEG within 270 days after the end of the 45-day negotiation period, the right of first offer will be reinstated and will apply to any future sale or future offer by CEG to sell all or a portion of the OpCo Interest.

CONFIDENTIAL INFORMATION

Section 7.1 Information. Each of the Partnership Entities and CEG (the “Recipient”) agrees that it will utilize any Confidential Information received from the other solely in connection with the performance of its obligations hereunder and the exercise by the Recipient of its rights and remedies hereunder and under Applicable Law, and all such Confidential Information will be subject to and bound by the provisions set forth in this Article VII. Upon termination of this Agreement, the Recipient will return or destroy all such Confidential Information (and cease all further use and disclosure of such Confidential Information) that has been provided to it, together with all reproductions thereof in the Recipient’s possession; provided that the Recipient will have the right to retain copies of any such information and records that relate to its performance of any services and the exercise of its rights and remedies hereunder and under Applicable Law, and all such copies and the information reflected thereon will be subject to the first sentence of this Section 7.1 and to Section 7.2.

Section 7.2 Definition. “Confidential Information” means any proprietary or confidential information that is competitively sensitive material or otherwise of value to a Party or its Affiliates and not generally known to the public, including trade secrets, scientific or technical information, design, invention, process, procedure, formula, improvements, product planning information, marketing strategies, financial information, information regarding operations, consumer and/or customer relationships, consumer and/or customer identities and profiles, sales estimates, business plans, and internal performance results relating to the past, present or future business activities of a Party or its Affiliates and the consumers, customers, clients and suppliers of any of the foregoing. Confidential Information includes such information as may be contained in or embodied by documents, substances, engineering and laboratory notebooks, reports, data, specifications, computer source code and object code, flow charts, databases, drawings, pilot

plants or demonstration or operating facilities, diagrams, specifications, bills of material, equipment, prototypes and models, and any other tangible manifestation (including data in computer or other digital format) of the foregoing; provided, however, that Confidential Information does not include information that a receiving Party can show (i) has been published or has otherwise become available to the general public as part of the public domain without breach of this Agreement, (ii) has been furnished or made known to the Recipient without any obligation to keep it confidential by a third party under circumstances which are not known to the Recipient to involve a breach of the third party’s obligations to a Party or (iii) was developed independently of information furnished or made available to the Recipient as contemplated under this Agreement.
