 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.

 (a) Subject to Section 7.2, the amount of general and administrative expenses reimbursed by the Partnership Group to the Buyer Entities (or, in the case of
Section 7.1(b)(i)(A) below, to the Williams Entities) for any MLP fiscal year shall not exceed the amounts calculated pursuant to Section 7.1(b) (for any MLP fiscal year, the “G&A Cap Amount”). 
  
 (b) (i) 2003 Fiscal Year. For the MLP fiscal year ending on December 31, 2003, the
G&A Cap Amount shall be calculated as follows: 
  
 (A) For the period
beginning on January 1, 2003 and ending on the day immediately preceding the Closing Date (the “2003 Pre-Closing Stub Period”), the amount of general and administrative expenses reimbursed by the Partnership Group to the Williams
Entities shall not exceed $37.9 million times a fraction, (X) the numerator of which is the number of successive whole months beginning with January 2003 and ending with the month in which the Closing occurs and (Y) the denominator of
which is twelve (12) (the “2003 Pre-Closing Cap”). To the extent that the Partnership Group reimbursed the Williams Entities for general and administrative expenses incurred in 2003 in excess of the 2003 Pre-Closing Cap, the Williams
Parties shall reimburse the MLP for any such excess amounts and shall make such payment no later than thirty (30) days following the Closing Date. To the extent that the Williams Entities paid unreimbursed general and administrative expenses up
to the 2003 Pre- 
  

 13 







 Closing Cap, Buyer shall use commercially reasonable efforts to cause the MLP to, make payment to the appropriate
Williams Entity of such unreimbursed amount no later than thirty (30) days following the Closing Date. 
  
 (B) For the period beginning with the Closing Date and ending on December 31, 2003 (the “2003 Post-Closing Stub Period”), the amount of general and administrative expenses reimbursed by the Partnership
Group to the Buyer Entities shall not exceed the sum of (1) the product of $37.9 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 December 2003 and (Y) the denominator of which is twelve (12) (the “2003 Post-Closing Cap”), plus (2) the amount of general and
administrative expenses incurred by or on behalf of the Partnership Group in excess of the 2003 Post-Closing Upper Cap Amount less any amounts duly reimbursed by the Williams Parties to the Buyer Entities pursuant to Section 7.2(c)(iii)(A).

  
 (ii) Succeeding Fiscal Years. For each succeeding MLP fiscal year beginning
with the MLP fiscal year ending December 31, 2004, the G&A Cap Amount shall be calculated as follows: 
  
 (A) The G&A Cap Amount from the preceding fiscal year (as may be adjusted pursuant to Section 7.1(b)(iii)) shall be increased by the greater of
(A) 7% per year and (B) the percentage increase in the Consumer Price Index — All Urban Consumers, U.S. City Average, Not Seasonally Adjusted. 
  
 (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 December 2003 and (Y) the
denominator of which is twelve (12) (the “2003 Post-Closing Upper Cap Amount”). 
  

 15 







 (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 
 Capital Expenditures 
  
 8.1 Williams Reimbursement of Partnership Group
Maintenance Capital Expenditures. The Williams Entities will reimburse the Partnership Group in each of the MLP’s 2003 and 2004 fiscal years for any reasonable and customary maintenance capital expenditures made by the Partnership Group, in
accordance with past practices, to maintain the assets of WPL, in either year, in excess of $19 million; provided, that the Williams Entities shall not be required to reimburse the Partnership Group in excess of an aggregate amount of $15 million
under this Section 8.1. 
  
 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

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

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. 
  
 9.3 Choice of Law; Submission to Jurisdiction. This Agreement shall be governed and construed in accordance with the internal and substantive laws of New York, and without regard to any conflicts of laws concepts that
would apply the substantive law of some other jurisdiction. Each party hereby submits to the jurisdiction of the state and federal courts in the State of New York and to venue in the Borough of Manhattan in the City of New York, New York.

 9.7 Effect of Waiver or Consent. No waiver of any provision of this Agreement shall be
effective unless set forth in writing by the party to be bound thereby. Except as otherwise expressly provided therein, no waiver or consent, express or implied, by any party to or of any breach or default by any Person in the performance by such
Person of its obligations hereunder shall be deemed or construed to be a consent or waiver to or of any other breach or default in the performance by such Person of the same or any other obligations of such Person hereunder. 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.

Section 9.2(a), this Agreement may be amended or modified from time to time only by the written agreement of all the parties hereto. Each such instrument shall be reduced to writing and shall be designated on its face an “Amendment”
