TAX RETURNS AND TAXES



     Section 2.1 Tax Returns and Payments.



     (a) Consolidated Returns and Combined Returns.



     Williams shall prepare and file all Consolidated Returns and Combined Returns that are
required to be filed by or with respect to any member of the WPX Group that is part of the Williams
Group, and shall pay any Taxes payable with respect to such Tax Returns. Williams shall prepare
all such Tax Returns in good faith and in accordance with the Tax Law. Williams shall, in its
discretion, make all determinations regarding the preparation of such Tax Returns, including
without limitation, determinations regarding the entities to be included in any Tax Return, the
making, modification or revocation of any election, the adoption or change of any Tax accounting
methods, and any other position to be taken on or in respect of such Tax Returns, including the
carryback of losses.



     (b) Other Tax Returns.



     WPX shall prepare and file all Tax Returns that are required to be filed by or with respect to
WPX or any of its direct or indirect subsidiaries, other than those Tax Returns described in
Section 2.1(a) above, and shall pay any Taxes payable with respect to such Tax Returns. At the
discretion of Williams, Williams may assist in the preparation of such Tax Returns as may be
requested by WPX, but shall have no obligation to pay any related Taxes.



     Section 2.2 Consents, Elections, Information.



     At the request of Williams, each member of the WPX Group shall (i) file any and all Tax
consents, Tax elections or other documents, (ii) take all actions necessary to effect or allow the
preparation and filing of all Tax Returns by Williams, and (iii) prepare and submit all
information in such form that Williams reasonably requests to enable Williams to prepare any
Tax Returns required by this Agreement. Each member of the WPX Group shall be bound by all of the
determinations made by Williams in preparing any such Tax Returns and no member of



-4-









 




the WPX Group shall take any position on a Tax Return with respect to an item of income, deduction, gain, loss,
or credit that is inconsistent with the reporting of such item on the Tax Returns prepared by Williams.




     Section 2.3 WPX Pro Forma Returns.



     (a) For each Tax period from the IPO until the WPX Group ceases to be part of a Consolidated
Return, Williams shall prepare a pro forma federal income Tax Return for the WPX Group (a “WPX Pro
Forma Consolidated Return”), based on the assumption that WPX is the common parent of the WPX
Group. For each Tax period from the IPO until the WPX Group ceases to be a part of any Combined
Returns, Williams shall prepare pro forma combined Tax Returns for the WPX Group for each
jurisdiction in which a Combined Return is filed (the “WPX Pro Forma Combined Returns”) based on
the assumption that WPX is not a subsidiary of Williams. The methods and processes described in
Sections 2.3(b), 2.3(c), and 2.3(d) below shall be followed in the preparation of the WPX Pro Forma
Returns. In addition, Williams may from time to time establish any other special procedures that
Williams may in its sole discretion deem necessary or appropriate to carry out the purposes of this Agreement.



     (b) Each WPX Pro Forma Return shall take into account solely the current income, deduction,
gain, loss, and credit items of the WPX Group, without regard to any carryovers or carrybacks from
prior or subsequent periods, and without regard to the AMT. Notwithstanding the foregoing, (i) any
employee compensation deduction resulting from the vesting of restricted stock, the exercise of
Williams stock options or similar equity-based compensation shall be reflected as a deduction to
Williams and not as a deduction on any WPX Pro Forma Returns, and (ii) the WPX Pro Forma Returns
shall not reflect any deduction under Section 199 of the Code computed on a separate company basis,
but shall reflect the amount that the WPX Group has contributed to the Williams Group consolidated
deduction under Section 199 of the Code, as determined by Williams in its sole discretion.



     (c) Each WPX Pro Forma Return shall reflect all elections and methods of accounting reflected
on the related Consolidated Returns or Combined Returns.



     (d) The relevant WPX Pro Forma Returns shall be prepared based on an actual or hypothetical
closing of the books of the WPX Group as of the IPO and as of such other time as the WPX Group may
cease to be part of a Consolidated Return or any Combined Returns, respectively, as the case may be.



     Section 2.4 Payments for WPX Pro Forma Returns.



     (a) For each WPX Pro Forma Consolidated Return, WPX shall pay to Williams the amount of the
Tax, if any, shown thereon. If the WPX Pro Forma Consolidated Return shows a credit or loss,
Williams shall pay to WPX an amount equal to (i) any such credits plus (ii) any such losses
multiplied by the highest marginal federal income tax rate applicable to corporations for the
relevant Tax year.



     (b) For each WPX Combined Pro Forma Return, WPX shall pay to Williams the amount of the Tax,
if any, shown thereon. If the WPX Pro Forma Combined Return shows a credit or loss, Williams shall
pay to WPX an amount equal to (i) any such credits plus (ii) any such losses multiplied by the
highest marginal Tax rate applicable thereto.



-5-









 





     (c) All payments required under this Section 2.4 shall be due no later than thirty days before
the Payment Date of the related Tax Return, and shall include any interest, penalties and additions
to Tax that would be due if such payments were made directly to the applicable Tax Authorities.



     Section 2.5 Carrybacks.



     If any member of the WPX Group realizes any losses, credits or other Tax Attributes that may
be carried back to a Consolidated Return or Combined Return, neither such member nor the WPX Group
shall be entitled to any payment or reimbursement from Williams or any member of the Williams Group
by reason of such carrybacks.



     Section 2.6 Carryovers.



     If Williams is required under the Code to allocate to the WPX Group or any of its members any
carryovers of any losses, credits or other Tax Attributes to periods following the External Spin,
Williams shall not be entitled to reimbursement from WPX by reason of such carryover.



ARTICLE III




REDETERMINATIONS AND ADJUSTMENTS



     Section 3.1 Redeterminations of Consolidated Returns.



     In the event of any adjustments in a Final Determination for a Consolidated Return, Williams
shall make corresponding adjustments to the related WPX Pro Forma Consolidated Return and WPX Pro
Forma Combined Returns consistent with the procedures described in Article II of this Agreement.
Within thirty days after such adjustment, Williams or WPX, as appropriate, shall make additional
payments to the other party reflecting such adjustment.



     Section 3.2 Redeterminations of Combined Returns



     In the event of any adjustments in a Final Determination other than those described in Section
3.1 above, WPX Pro Forma Returns shall not be adjusted and no additional payments shall be required
between Williams and WPX.



ARTICLE IV




SPIN



     Section 4.1 No Obligation to Effect External Spin.



     Although Williams intends to effect the External Spin, the parties agree that Williams is
under no obligation to effect the External Spin at any time.



     Section 4.2 Spin Representations and Warranties.



-6-









 





     (a) Each of WPX and Williams represents and warrants that it has examined the Private Ruling
Application and any Tax Opinion issued on or prior to the date hereof and that the facts presented
and the representations made therein are true, correct and complete; provided that in the event
that a Private Ruling is not obtained with respect to the Spin, neither WPX nor Williams shall be
deemed to make any representations regarding the Private Ruling Application.



     (b) Each of WPX and Williams represents and warrants that it has not taken and has no plan or
intention of taking any action or failing to take any action nor knows of any circumstance that
could reasonably be expected to cause any representation or factual statement made in this
Agreement, the Separation Agreement, the Private Ruling Application or any Tax Opinion issued on or
prior to the date hereof to be untrue; provided that, in the event that a Private Ruling is not
obtained with respect to the Spin, neither WPX nor Williams shall be deemed to make any
representations regarding the Private Ruling Application.



     (c) Each of Williams and WPX represents and warrants that, during the two-year period ending
on the date hereof, there was no “agreement, understanding, arrangement, or substantial
negotiations” (as such terms are defined in Regulation Section 1.355-7(h)(1), and hereinafter
referred to as the “Section 355(e) Agreements”) (other than with respect to the IPO) that related
to a plan pursuant to which one or more persons would acquire directly or indirectly stock
representing a 50% or greater interest (within the meaning of Section 355(e) and the Regulations
thereunder) in Williams, WPX or Apco (any such plan hereinafter referred to as a “Section 355(e) Plan”).



     (d) Each of Williams and WPX represents and warrants that it has no current plan or intention
to enter into any Section 355(e) Agreements that relate to a Section 355(e) Plan.



     Section 4.3 Spin Covenants.



     (a) Each of WPX and Williams covenants that it will not and will not allow any officers or
directors of any member of the WPX Group or the Williams Group, respectively, to take any action or
fail to take any action that (i) would create a risk that the Spin will fail to qualify as a
tax-free distribution pursuant to Section 355 and Section 368(a)(1)(D) of the Code, (ii) would be
inconsistent with any factual statement or any representation made hereunder or in the Separation
Agreement or in connection with the Private Ruling, the Private Ruling Application, or any Tax
Opinion, or any condition or restriction imposed thereby, or (iii) would create a risk for the Spin
to trigger gain under Section 355(d) or Section 355(e) of the Code.



     (b) Except as otherwise required by the Tax Law or as a result of a Final Determination, each
of WPX and Williams covenants that it will not and will not allow any officers or directors of any
member of the WPX Group or the Williams Group, respectively, to take any position with respect to
an item of income, deduction, gain, loss, or credit on a Tax
Return that is inconsistent with the treatment of the Spin under Section 355 and Section
368(a)(1)(D) of the Code (or analogous status under state, local or foreign law).



     (c) If during the period commencing on the date hereof and ending two (2) years after the Spin
Date any officers and directors of any member of the Williams Group or the WPX Group becomes aware
of a matter or transaction that could affect the status of the Spin under



-7-









 




Section 355 or Section 368(a)(1)(D) of the Code, Williams and WPX covenant to inform each other of
such matter or transaction. The parties shall attempt in good faith to take reasonable action or
reasonably refrain from taking action to ensure the continued qualification of the Spin under the
foregoing sections of the Code. If the parties are unable to agree on a course of action, WPX shall
be required to take any course of action consistent with Tax Law that Williams reasonably determines,
in good faith and taking into account the interests of WPX and Williams, in order to implement the
provisions of Section 4.3(a). This Section 4.3(c) shall not apply as to any matters or
transactions with respect to which the IRS has issued (i) a private letter ruling to Williams or
WPX or (ii) other guidance that can be relied upon conclusively to the effect that the transaction
or event at issue does not adversely affect the Spin under Section 355 or Section 368(a)(1)(D) of
the Code.




     (d) WPX covenants that its officers and directors will not discuss any acquisitions of the
Stock of WPX or any WPX Group member during the two-year period beginning on the Spin Date without
permission from Williams, such permission not to be unreasonably withheld.



ARTICLE V




INDEMNITIES



     Section 5.1 Spin Indemnities.



     (a) Williams shall be responsible for and shall indemnify and hold harmless each member of the
WPX Group from and against all Spin Taxes, except for those Spin Taxes for which the WPX Group is
responsible under Section 5.1(b) of this Agreement.



     (b) WPX shall be responsible for and shall indemnify, defend and hold harmless each member of
the Williams Group from and against all Spin Taxes that are incurred by any member of the Williams
Group by reason of the breach by any member of the WPX Group of any of its representations or
covenants hereunder or in the Separation Agreement, or made in connection with the Private Ruling,
Private Ruling Application or Tax Opinion.



     Section 5.2 Transfer Tax Indemnities.



     Williams shall indemnify and hold harmless each member of the WPX Group for any transfer Taxes
arising solely as a result of transferring any assets to any member of the WPX Group on or prior to

     Section 5.3 No Other Liability.



     Except as specifically provided in this Agreement, WPX and Williams shall have no liability to
each other with respect to Taxes.

     For all Tax purposes, and notwithstanding any other provision of this Agreement, to the extent
permitted by applicable law, the parties hereto shall treat any payment made pursuant to



-8-









 




this Agreement (other than interest thereon) as a capital contribution or dividend distribution, as the
case may be (except to the extent that the parties treat such payment as the settlement of an
intercompany liability), made immediately before WPX ceased to be an includible corporation in the
Williams Group under Section 1504 of the Code and, accordingly, as not includible in the taxable
income of the recipient. If any payment under this Agreement is not permitted to be so treated
(because, for example, the payment relates to an event occurring after such date) or as a result of
a Final Determination it is determined that the receipt or accrual of any payment made under this
Agreement is taxable to the recipient of such payment, the party making the payment shall pay to
the recipient an amount equal to any increase in the income Taxes of the recipient as a result of
receiving the payment (grossed up to take into account such payment, if applicable).

except that any settlement that will result in liability to WPX shall be subject to the consent
of WPX, which consent shall not be unreasonably delayed, denied or withheld.
