Environmental and Right-of-Way Indemnification Procedures

6.1 (a) Buyer agrees that within a reasonable period of time after any Partnership Entity becomes aware of facts giving rise to a claim for indemnification pursuant to Sections 4.1, 5.1 or 5.2, Buyer will use its reasonable best efforts to cause such Partnership Entity to provide notice thereof in writing to Williams, specifying the nature of and specific basis for such claim.

(b) Except as provided in this Section 6.1(b), Williams shall have the right to control all aspects of the defense of (and any counterclaims with respect to) any claims brought against the Partnership Entities that are covered by the indemnification set forth in Sections 4.1, 5.1 or 5.2, including, without limitation, the selection of counsel, determination of whether to appeal any decision of any court 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 of the Partnership Entities unless it includes a full and unconditional release of the Partnership Entities from all liability with respect to such matter or issues, as the case may be, the sole relief provided is monetary damages that are paid in full by the Williams Parties, and there is no admission or statement of fault or culpability on the part of any Partnership Entity.

(c) Buyer agrees to use its reasonable best efforts to cause the Partnership Entities, at their own cost and expense, to cooperate fully with Williams with respect to all aspects of the defense of any claims covered by the indemnification set forth in Sections 4.1, 5.1 or 5.2, including, without limitation, the prompt furnishing to Williams of any correspondence or other notice relating thereto that the Partnership Entities may receive, permitting the names of the Partnership Entities to be utilized in connection with such defense, the making available to Williams of any files, records or other information of the Partnership Entities that Williams reasonably considers relevant to such defense and the making reasonably available to Williams, during normal business hours, of any employees of the Partnership Entities; provided, however, that in connection therewith Williams agrees to use reasonable best efforts to minimize the impact thereof on the operations of such Partnership Entities. In no event shall the obligation of Buyer to use its reasonable best efforts to cause the Partnership Entities to cooperate with Williams as set forth in the immediately preceding sentence be construed as imposing upon the Buyer or the Partnership Entities 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 VI, it being agreed

12

that the Williams Parties, jointly and severally, shall pay the fees and expenses of such counsel; provided, further, that Buyer or the Partnership Entities may hire and pay for separate counsel in connection with any such defense, at the Buyers or the MLP’s own option, cost and expense, as the case may be; provided, further, that the Williams Parties, jointly and severally, shall pay the fees and expenses of separate counsel for the Buyer or the Partnership Entities if (i) the Williams Parties have agreed to pay such fees and expenses or (ii) counsel for the Williams Parties reasonably determines that representation of both the Williams Parties, on the one hand, and the Partnership Entities, on the other hand, by the same counsel would create a conflict of interest.  Williams agrees to keep any counsel hired by the Partnership Entities reasonably informed as to the status of any such defense, but Williams shall have the right to retain sole control over such defense except as provided above.

(d) In determining the amount of any loss, cost, damage or expense for which any of the Partnership Entities are to be indemnified under Sections 4.1, 5.1 or 5.2, the gross amount of the indemnification will be reduced by (i) any insurance proceeds realized or to be realized by the Partnership Entities, and such correlative insurance benefit shall be net of any incremental insurance premium that becomes due and payable by the Partnership Entities as a result of such claim and (ii) all amounts recovered or recoverable by any Partnership Entity under contractual indemnities from third Persons as described in Section 4.1.

(B)   For purposes of calculating the initial increase in the G&A Cap Amount for the MLP fiscal year ending on December 31, 2004, the G&A Cap Amount for the 2003 fiscal year shall be $37.9 million (as may be adjusted pursuant to Section 7.1(b)(iii) for acquisitions, construction, capital improvements, replacements or expansions occurring in 2003).

(iii) Adjustment for Acquisitions and Other Events.  If, after the Closing Date, the Partnership Group (A) makes an acquisition, (B) constructs or causes to be constructed any assets to be owned, leased or operated by any member of the Partnership Group or (C) makes or causes to be made any capital improvements, replacements or expansions of any assets owned, leased or operated by any member of the Partnership Group, the amount of general and administrative expenses reimbursed by the Partnership Group to the Buyer Entities will be increased by the Buyer’s good faith reasonable estimate of the additional amount of annual general and administrative expenses to be incurred by or on behalf of the Partnership Group with respect to such acquisition, construction, capital improvement, replacement or expansion.  The pro rata portion of the additional general and administrative expenses shall be added to the G&A Cap Amount and the Upper Cap Amount in the year in which such acquisition, construction, capital

14

improvement, replacement or expansion occurs for the portion of the year occurring thereafter and the full amount of such general and administrative expenses shall be added to the G&A Cap Amount and the Upper Cap Amount thereafter.

7.2 Certain Limitations.  The provisions of Section 7.1 shall be subject to the following limitations:

(a) Expiration of G&A Cap.  The amount of general and administrative expenses reimbursed by the Partnership Group to the Buyer Entities shall not be limited under this Agreement with respect to any fiscal year ending after December 31, 2010.

(b) Certain Expenses Not Included.  General and administrative expenses with respect to the following matters shall be excluded in determining limitations herein on the amount of general and administrative expenses that are required to be reimbursed by the Partnership Group or the Williams Parties to the Buyer Entities:

(i) expenses associated with equity-based incentive compensation plans;

(ii) general and administrative expenses incurred by Buyer that are covered under Section 4.15 to the Purchase Agreement, regardless of whether in excess of the Expense Limit (as defined in Section 4.15 to the Purchase Agreement), it being understood that to the extent the Williams Parties reimburse Buyer for general and administrative expenses in excess of the Expense Limit, Buyer shall promptly pay any such reimbursements to the MLP by wire transfer of immediately available funds to an account or accounts designated in writing by the MLP; or

(iii) general and administrative expenses incurred in connection with providing Services (as defined by the Services Agreement) under the Services Agreement.

(c) Upper Cap Amount.

(i) Notwithstanding the limitations in Section 7.1 on the Partnership Group’s reimbursement obligations for general and administrative expenses in excess of the G&A Cap Amount, the Partnership Group (or in the case of Section 7.2(c)(iii), the Williams Parties) shall be required to reimburse the Buyer Entities for general and administrative expenses incurred on behalf of the Partnership Group in any MLP fiscal year in excess of the Upper Cap Amount as calculated below (the “Upper Cap Amount”).

(ii) The Upper Cap Amount shall be calculated as follows:

(A)   For the 2003 Post-Closing Stub Period, the Upper Cap Amount shall be equal to the product of $49.3 million (as may be adjusted pursuant to Section 7.1(b)(iii)) times a fraction, (X) the numerator of which is the number of successive whole months beginning with the month following the month in which the Closing occurs and ending with month of

15

December 2003 and (Y) the denominator of which is twelve (12) (the “2003 Post-Closing Upper Cap Amount”).

(B)   For each succeeding MLP fiscal year beginning with the MLP fiscal year ending December 31, 2004, the Upper Cap Amount shall be calculated as follows:

(1) The Upper Cap Amount from the preceding fiscal year (as may be adjusted pursuant to Section 7.1(b)(iii)) shall be increased annually by the lesser of (A) 2.5% per year and (B) the percentage increase in the Consumer Price Index — All Urban Consumers, U.S. City Average, Not Seasonally Adjusted.

(2) For purposes of calculating the initial increase in the Upper Cap Amount for the MLP fiscal year ending on December 31, 2004, the Upper Cap Amount for the 2003 fiscal year shall be $49.3 million (as may be adjusted pursuant to Section 7.1(b)(iii) for acquisitions, construction, capital improvements, replacements and expansions occurring in 2003).

(iii) For the twelve months immediately following the Closing Date, the Williams Parties shall be required to reimburse the Buyer Entities for any and all general and administrative expenses incurred by or on behalf of the Partnership Group in excess of the Upper Cap Amount, as follows:

(A)   If, for the 2003 Post-Closing Stub Period, the general and administrative expenses incurred by or on behalf of the Partnership Group are in an amount in excess of 2003 Post-Closing Upper Cap Amount, the Williams Parties, jointly and severally, shall be required to reimburse the Buyer Entities in full for the amount of such excess and shall make such payment no later than thirty (30) days after the last day of the 2003 Post-Closing Stub Period by wire transfer of immediately available funds to an account or accounts designated in writing by the Buyer Entities.

(B)   If, for the period beginning on January 1, 2004 and ending on the last day of the month in which the first anniversary of the Closing Date occurs (the “2004 Stub Period”), the general and administrative expenses incurred by or on behalf of the Partnership Group exceed the Upper Cap Amount for the MLP fiscal year ended December 31, 2004 multiplied by a fraction, (X) the numerator of which is the number of successive months beginning with January 2004 and ending with the month in which the 2004 Stub Period ends and (Y) the denominator of which is twelve (12) (the “2004 Stub Period Upper Cap Amount”), the Williams Parties, jointly and severally, shall be required to reimburse the Buyer Entities in full for the amount of such excess and shall make such payment no later than thirty (30) days after the last day of the 2004 Stub Period by wire transfer of immediately available funds to an account or accounts designated in

16

writing by the Buyer Entities.  If Buyer becomes obligated to pay the 5% premium for transition services pursuant to the final proviso in Section 4(a) of the Transition Services Agreement, then for purposes of the immediately preceding sentence, the 2004 Stub Period Upper Cap Amount shall be increased by the portion of such premium constituting general and administrative expenses of the Partnership Group attributable to the 2004 Stub Period.

(C)   Buyer shall, and shall cause each of the other Buyer Entities to, use good faith efforts to minimize the amount of general and administrative expenses incurred by any of the Buyer Entities and for which the Williams Parties would be required to reimburse the Buyer Entities under this Section 7.2(c)(iii).

(D)   Notwithstanding any other provision of this Article VII, the Williams Entities will not have any obligations to reimburse the Buyer Entities for general and administrative expenses incurred on behalf of the Partnership Group or otherwise, except as specifically provided in this Section 7.2(c)(iii).

(iv) Except as provided in Section 7.2(c)(iii), the Partnership Group shall be required to reimburse the Buyer Entities for any and all general and administrative expenses in excess of the Upper Cap Amount incurred by or on behalf of the Partnership Group in any MLP fiscal year.

7.3 No Affect on Section 7.4 of the MLP Agreement.  Nothing in this Article VII is intended or shall be construed to affect or modify the terms and conditions of Section 7.4 of the MLP Agreement.

ARTICLE VIII

ARTICLE IX
Miscellaneous

9.1 Payments; Disputed Amounts; Audit Rights.

(a) Except as otherwise provided herein, any payments to be made by the Williams Entities to Buyer or the Partnership Entities under this Agreement shall be made by the Williams Entities within sixty (60) days of receipt of a written request for such payment from

17

Buyer (which request shall contain a description in reasonable detail of the individual costs and expenses that comprise the aggregate amount of the payment requested) (a “Payment Request”). In the event of a good faith dispute as to the amount of such payment, the applicable Williams Entity shall give written notice of such dispute on or before the due date with respect to all or any portion of  the Payment Request, with the particulars of such dispute. Upon receipt of such notice, Buyer shall, or shall use its reasonable best efforts to cause the Partnership Entities to, furnish to the applicable Williams Entity additional supporting documentation to reasonably substantiate the amount of the Payment Request.  Upon delivery of such additional documentation, the applicable Williams Entity and the Buyer Entities shall cooperate and use their reasonable best efforts to resolve such dispute.  If they are unable to resolve their dispute within twenty (20) business days of the delivery of such additional supporting documentation to the applicable Williams Entity, then the dispute shall be referred for resolution by a firm of independent accountants of nationally recognized standing reasonably satisfactory to each of Buyer and the applicable Williams Entity (the “Accounting Referee”), which shall determine the disputed amounts within thirty (30) days of the referral of such dispute to such Accounting Referee.  The determination of the Accounting Referee shall not require the applicable Williams Entity to pay more than the amount in dispute nor require Buyer or any Partnership Entity to return any amount previously paid by the applicable Williams Entity.  The fees and expenses of the Accounting Referee shall be borne equally by the applicable Williams Entity, on the one hand, and Buyer or a member of the Partnership Entities, on the other hand.  The determination of the Accounting Referee shall be finally binding.  If any dispute is resolved in favor of Buyer or any Partnership Entity, the applicable Williams Entity shall make payment to Buyer or the applicable Partnership Entity within thirty (30) days of resolution of the dispute.  Notwithstanding the foregoing, in no event shall the Williams Entities be entitled to withhold any amounts other than those portions of the applicable payment that are in dispute.

(b) Williams shall have the right, at any time within six (6) months after the date of any payment by Williams to Buyer or the Partnership Entities pursuant to a Payment Request to audit those books and records of Buyer and/or any Partnership Entity that incurred costs or expenses attributable to such Payment Request or which books and records relate thereto, to verify the amount reflected on such Payment Request.  Any such audit shall be conducted during normal business hours by Williams or its designated auditor after ten (10) days prior written notice to Buyer, at Williams’ sole cost and expense, in the offices of Buyer and the relevant Partnership Entities or such other location as may be mutually agreed.  Buyer shall cooperate and shall use its reasonable best efforts to cause any relevant Partnership Entity to cooperate with and provide reasonable assistance to Williams and/or its auditor in connection with the performance of any such audit.  Williams shall assert any claim for refund of amounts reimbursed to Buyer or the Partnership Entities under the audited Payment Request within sixty (60) days after the completion of the audit.  Buyer shall have sixty (60) days from receipt of Williams’ claim for refund to respond.  If Buyer does not dispute Williams’ refund claim, Buyer or the applicable Partnership Entity shall pay such refund within such 60-day period.  Should Buyer dispute the claim and refuse to pay any refund claim by Williams resulting from the exercise of Williams’ audit rights, the parties will refer the dispute to an Accounting Referee in the manner described in Section 9.1(a) above.

18

9.2 Third-Party Beneficiary; Assignment; Enforcement.

(a) Each of Buyer and the Williams Parties specifically intends that each entity comprising the Partnership Entities or the Partnership Group, as applicable, shall be entitled to assert rights and remedies hereunder as third-party beneficiaries hereto with respect to those provisions of this Agreement affording a right, benefit or privilege to any such entity.  Notwithstanding anything else in this Agreement, pursuant to Section 4.25 of the Purchase Agreement, no provision of this Agreement with respect to which any of the entities comprising the Partnership Entities or the Partnership Group, as applicable, is a third-party beneficiary shall be amended, modified, waived or terminated by a party hereto without the express prior written approval of the MLP, and if the General Partner, in its capacity as general partner of the MLP, determines in its reasonable discretion that such an amendment, modification, waiver or termination is reasonably likely to adversely affect the holders of common units representing limited partner interests in the MLP, such amendment, modification, waiver of termination must also be approved by Special Approval (as such term is defined in the MLP Agreement).

(b) No party shall have the right to assign its rights or obligations under this Agreement without the consent of the other parties hereto.

(c) The parties hereto agree that irreparable damage would occur if any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached.  It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof, this being in addition to any other remedy to which they are entitled at law or in equity.  The third-party beneficiaries to whom certain rights and remedies under this Agreement extend as contemplated under Section 9.2(a) above shall also be entitled to enforce this Agreement in the manner provided in this Section 9.2(c).  Notwithstanding anything else in this Agreement, the provisions of this Agreement are enforceable solely by the parties to this Agreement and the third-party beneficiaries identified in Section 9.2(a) above, and no Limited Partner (other than Buyer), Assignee or other Person (other than a permitted assignee under Section 9.2(b)) may enforce any provision of this Agreement or compel any party to this Agreement to comply with the terms of this Agreement.

Failure on the part of a party to complain of any act of any Person or to declare any Person in default, irrespective of how long such failure continues, shall not constitute a waiver by such party of its rights hereunder until the applicable statute of limitations period has run.

9.8 Amendment or Modification.  Subject to the second sentence of Section 9.2(a), this Agreement may be amended or modified from time to time only by the written agreement of

20
