Section 3.3 Objection. The Partnership may object to any amounts for any Service at any time before, at the time of or after payment is made, provided such objection is made in writing to CNP within 30 days following the date of the disputed invoice. The Partnership shall timely pay the disputed items in full pending resolution of the dispute in accordance with Section 3.4. Payment of any amount shall not constitute approval thereof.

The Accounting Referee shall deliver to the Parties as promptly as practicable (but in any event no later than 30 days from the date of engagement of the Accounting Referee), a report setting forth the Accounting Referee’s determination of the appropriate resolution of the dispute. Such determination shall be final and binding upon the Parties. The cost of such review and report shall be borne equally by each Party involved in the dispute.

Section 3.5 Error Correction. CNP shall make adjustments to charges as required to reflect the discovery of errors or omissions in charges; provided, however, that any errors or omissions the correction of which would result in additional or increased charges or fees for Services must be corrected within two years after the date of the related invoice.

Section 3.6 Taxes. All transfer taxes, excises, fees or other charges (including value added, sales, use or receipts taxes, but not including a tax on or measured by the income, net or gross revenues, business activity or capital of CNP), or any increase therein, now or hereafter imposed directly or indirectly by Law upon any fees paid hereunder for Services, which CNP is required to pay or incur in connection with the provision of Services hereunder (“Tax”), shall be passed on to the Partnership as an explicit surcharge and shall be paid by the Partnership in addition to any payment of fees for Services, whether included in the applicable payment of fees for Services, or added retroactively. If the Partnership submits to CNP a timely and valid resale or other exemption certificate reasonably acceptable to CNP and sufficient to support the exemption from Tax, then such Tax will not be added to the fee for Services payable pursuant to Section 3.1; provided, however, that if CNP is ever required to pay such Tax, the Partnership will promptly reimburse CNP for such Tax, including any interest, penalties and attorney’s fees related thereto.

(b) The Indemnifying Party will have the right to control all aspects of the defense of (and any counterclaims with respect to) any claims brought against the Indemnified Party that are covered by the indemnification set forth in this Agreement, including the selection of counsel, determination of whether to appeal any decision of any court or similar authority, and the settling of any such matter or any issues relating thereto; provided, however, that no such settlement will be entered into without the consent of the Indemnified Party unless it includes a full release of the Indemnified Party for such matter or issues, as the case may be.

(c) The Indemnified Party agrees to cooperate fully with the Indemnifying Party with respect to all aspects of the defense of any claims covered by the indemnification set forth in this Agreement, including the prompt furnishing to the Indemnifying Party of any correspondence or other notice relating thereto that the Indemnified Party may receive, permitting the names of the Indemnified Party to be utilized in connection with such defense, the making available to the Indemnifying Party of any files, records, or other information of the Indemnified Party that the Indemnifying Party considers relevant to such defense and the making available to the Indemnifying Party of any employees of the Indemnified Party; provided, however, that in connection therewith the Indemnifying Party agrees to use reasonable efforts to minimize the impact thereof 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.

Miscellaneous

Section 13.2 Amendment. No amendment to this Agreement will be effective unless made in writing and signed by both Parties.

Section 13.3 Severability. If any provision of this Agreement is invalid, illegal, or incapable of being enforced by any rule of applicable Law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated by this Agreement are not affected in any manner materially adverse to any Party. Upon such determination that any term or other provision is invalid, illegal, or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated by this Agreement are consummated as originally contemplated to the fullest extent possible.

Neither Party may assign, transfer or otherwise alienate this Agreement or any of its rights, interests or obligations under this Agreement (whether by operation of Law or otherwise) without the consent of the other Party.

Section 13.6 Counterparts. This Agreement may be executed in one or more counterparts (including by facsimile or other electronic transmission), each of which shall be deemed an original, but all of which together shall constitute one instrument.

Section 13.7 Construction.

(a) The division of this Agreement into articles, sections and other portions and the insertion of headings are for convenience of reference only and shall not affect the construction or interpretation hereof. Unless otherwise indicated, all references to an “Article” or “Section” followed by a number or a letter refer to the specified Article or Section of this Agreement. The Schedule attached to this Agreement is hereby incorporated by reference into this Agreement and form part hereof. Unless otherwise indicated, all references to a “Schedule” followed by a letter refer to the specified Schedule to this Agreement. The terms “this Agreement,” “hereof,” “herein” and “hereunder” and similar expressions refer to this Agreement and not to any particular Article, Section or other portion hereof.

Reference to any Party hereto is also a reference to such Party’s permitted successors and assigns.

(c) The Parties hereto have participated jointly in the negotiation and drafting of this Agreement. No provision of this Agreement will be interpreted in favor of, or against, any of the Parties to this Agreement by reason of the extent to which any such Party or its counsel participated in the drafting thereof or by reason of the extent to which any such provision is inconsistent with any prior draft of this Agreement, and no rule of strict construction will be applied against any Party hereto. This Agreement will not be interpreted or construed to require any Person to take any action, or fail to take any action, if to do so would violate any applicable Law.
