These general and administrative services shall be

substantially identical in nature and quality to the services of such type previously provided by Targa in connection with their management and operation of the North Texas Assets prior to their acquisition by the Partnership. In the event that the Partnership Group makes any acquisitions of assets or businesses from Targa or its Affiliates during the first three years following the date of this Agreement, Targa will similarly provide general and administrative services that are substantially identical in nature and quality to the services of such type previously provided by Targa in connection with their management and operation of such assets or businesses prior to their acquisition by the Partnership.

           (b) Subject to the provisions of Section 2.3(c) below, the Partnership Group hereby agrees to reimburse Targa for all expenses and expenditures Targa or its Affiliates incur or payments they make on behalf of the Partnership Group for these general and administrative services.

In the event that the Partnership Group makes any acquisitions of assets or businesses or the business of the Partnership Group otherwise expands during the first three years following the date of this Agreement, then the G&A Expenses Limit shall be appropriately increased in order to account for adjustments in the nature and extent of the general and administrative services by Targa to the Partnership Group, with any such increase in the G&A Expenses Limit subject to the approval of the Conflicts Committee. After the third anniversary of the date of this Agreement, the G&A Expenses Limit will no longer apply and the General Partner will determine the amount of general and administrative expenses that will be properly allocated to the Partnership in accordance with the terms of the Partnership Agreement. The G&A Expenses Limit shall not apply to reimbursement for direct expenses of the Partnership as provided in Section 2.2.

     2.2 Reimbursement for Direct Expenses.

           (a) The Partnership Group hereby agrees to reimburse Targa and its Affiliates for all direct expenses and expenditures they incur or payments they make on behalf of the Partnership Group, including, but not limited to, (i) salaries of operational personnel performing services on the Partnership Group’s behalf, the cost of employee benefits for such personnel and general and administrative expense associated with such personnel, (ii) capital expenditures, (iii) maintenance and repair costs, (iv) taxes and (v) direct expenses, including operating expenses and certain allocated operating expenses, associated with the ownership and operation of the North Texas Assets.

           (a) Subject to the provisions of Section 3.3, Targa shall indemnify, defend and hold harmless the Partnership Group and the Partnership Indemnitees from and against any Losses suffered or incurred by the Partnership Group or any Partnership Indemnitee by reason of or arising out of:

     (i) the failure of the Partnership Group to be the owner of valid and indefeasible easement rights, leasehold and/or fee ownership interests in and to the lands on which are located any North Texas Assets, and such failure renders the Partnership Group liable or unable to use or operate the North Texas Assets in substantially the same manner that the North Texas Assets were used and operated by Targa and its Affiliates immediately prior to the Closing Date as described in the Registration Statement;

     (iv) all pending legal actions as of the Closing Date against one or more Partnership Group Members involving or otherwise relating to the North Texas Assets;

provided, however, that, in the case of clauses (i), (ii) and (iv) above, such indemnification obligations shall survive for three (3) years from the Closing Date; and that in the case of clause (iii) above, such indemnification obligations shall survive after the expiration of any applicable statute of limitations;

(b) In addition to and not in limitation of the indemnification provided under this Article III, the Partnership Group shall indemnify, defend, and hold harmless Targa and its Affiliates, other than any Partnership Group Member, from and against any Losses suffered or incurred by Targa and its Affiliates, other than any Partnership Group Member, by reason of or

arising out of events and conditions associated with the operation of the North Texas Assets that occurs on or after the Closing Date.

     3.3 Indemnification Procedures.

           (a) The Indemnified Party agrees that within a reasonable period of time after it becomes aware of facts giving rise to a claim for indemnification pursuant to this Article III, they will provide notice thereof in writing to the Indemnifying Party specifying the nature of and specific basis for such claim; provided, however, that the Indemnified Party shall not submit claims more frequently than once a calendar quarter (or twice in the case of the last calendar quarter prior to the expiration of the applicable indemnity coverage under this Agreement).

           (b) The Indemnifying Party shall 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 Article III, including, without limitation, 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 shall be entered into without the consent (which consent shall not be unreasonably withheld, conditioned or delayed) of the Indemnified Party unless it includes a full release of the Indemnified Party from 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 Article III, including, without limitation, 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 Section 3.3. In no event shall 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 III; 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 reasonably informed as to the status of any such defense, but the Indemnifying Party shall have the right to retain sole control over such defense.

           (d) In determining the amount of any loss, cost, damage or expense for which the Indemnified Party is entitled to indemnification under this Agreement, the gross amount of the indemnification will be reduced by (i) any insurance proceeds realized by the Indemnified Party, and such correlative insurance benefit shall be net of any incremental insurance premium

that becomes due and payable by the Indemnified Party as a result of such claim and (ii) all amounts recovered by the Indemnified Party under contractual indemnities from third Persons.
