(i) KMC Group Tax Liability. As reasonably determined by PKS, the KMC Group's allocable share of the Consolidated Group federal Income Tax liability shall equal the federal Income Tax computed by taking into account Tax Items of the KMC Group as if the KMC Group filed its own stand-alone consolidated federal Income Tax Return. (ii) PKS Group Tax Liability. The PKS Group's allocable share of the Consolidated Group federal Income Tax liability shall equal the excess of the Consolidated Group federal Income Tax liability over the sum of (A) the KMC Group allocable share of such liability, as determined under Section 3.2(a)(i) above, plus (B) any such federal Income Tax liability allocable to the Level 3 Group or any other entity that is not a member of the PKS Group or the KMC Group pursuant to the PKS/Level 3 Tax Sharing Agreement. (iii) Prior Allocation. If a deficiency or refund in the Consolidated Group's federal Income Tax liability is subsequently proposed or determined, for purposes of this Section 3.2, it shall be assumed for tax years prior to Taxable Year 1999 that (A) any allocation of the Consolidated Group's federal Income Tax liability made prior to the date of this Agreement between the Parties was consistent with this Section 3.2 and (B) any obligations between the Parties in respect of such allocation have been fully satisfied. (b) Except as otherwise provided herein, for each taxable period ending on or before (or each taxable period including) the Distribution Date, KMC and the members of the KMC Group shall pay and be solely responsible for any federal Income Taxes (including estimated Taxes) that are allocable under this Agreement to KMC and the members of the KMC Group. KMC shall indemnify PKS and the PKS Affiliates for and hold them harmless from any such Taxes.

Section 3.3. State Income Taxes. (a) For each taxable period ending on or before (or each taxable period including) the Distribution Date for which the liability of the members of the PKS Group and the KMC Group (and, if applicable, the Level 3 Group) is determined on a Combined Return, the Combined State Income Tax Liability including estimated Taxes and subsequently determined deficiencies in such Taxes, shall be allocated between the Parties as set forth below: (i) PKS Group: The PKS Group's allocable share of the Combined State Income Tax Liability in each Combined Jurisdiction shall be equal to the excess of the Combined State Income Tax Liability over the sum of (A) KMC Group Pro-Forma Liability as determined in Section 3.3 (a) (ii), plus (B) any Combined State Income Tax Liability allocable to the Level 3 Group and any other entity that is not a member of the PKS Group or the KMC Group pursuant to the PKS/Level 3 Tax Sharing Agreement. (ii) KMC Group: The KMC Group's allocable share of the Combined State Income Tax Liability in each applicable state shall be equal to the "KMC Group Pro-Forma Liability". The "KMC Group Pro-Forma Liability" shall equal the pro-forma liability of the KMC Affiliates included in the Combined Return computed utilizing the Combined Return apportionment factor (e.g., in the case where a member of the Level 3 Group is included in the Combined Return, the "Combined State Income Tax Return" apportionment factor as provided in the PKS/Level 3 Tax Sharing Agreement) and all applicable Tax Items on a pro-forma basis (as reasonably determined by PKS); provided, however, to the extent Tax Items included in the KMC Group Pro-Forma Liability are not utilized in the Combined Return (or if applicable the "Combined State Income Tax Return" as defined in the PKS/Level 3 Agreement), these Tax Items shall be excluded from the KMC Group Pro-Forma Liability computation. If such pro-forma computation results in a negative KMC Group Pro-Forma Liability, PKS shall pay KMC only to the extent PKS realizes a Tax Benefit from the Combined Jurisdiction or receives payment from the Level 3 Group (in each case relating to the Tax Items causing the negative KMC Group Pro-Forma Liability). If such pro-forma computation results in a KMC Group Pro-Forma Liability greater than the Combined State Income Tax Liability (reduced by any such liability allocable to the Level 3 Group and any other entity that is not a member of the PKS Group or the KMC Group pursuant to the PKS/Level 3 Tax Sharing Agreement), the KMC Group's allocable share of the Combined State Income Tax Liability shall be 100% and any excess of such KMC Group Pro-forma Liability over the Combined State Income Tax Liability (reduced by any such liability allocable to the Level 3 Group and any other entity that is not a member of the PKS Group or the KMC Group pursuant to the PKS/Level 3 Tax Sharing Agreement) shall be paid by the KMC Group to the PKS Group. (b) Except as otherwise provided herein, for each taxable period ending on or before (or each taxable period including) the Distribution Date, KMC and the members of the KMC Group shall be solely responsible for any State Income Taxes that are allocable under Section 3.3(a) to KMC or any of the members of the KMC Group. KMC and the members of the KMC Group shall indemnify PKS and the PKS Affiliates for and hold them harmless from any 10 11 such Taxes. Except as otherwise provided herein, for each taxable period ending on or before (or each taxable period including) the Distribution Date, PKS and the members of the PKS Group shall be solely responsible for any State Income Taxes that are allocable under Section 3.3(a) to PKS or any of the members of the PKS Group. Except as otherwise provided herein, PKS and the members of the PKS Group shall indemnify KMC and all members of the KMC Group for and hold them harmless from any such Taxes. (c) Except as otherwise provided herein, for each taxable period ending on or before (or each taxable period including) the Distribution Date, KMC and the members of the KMC Group shall be solely responsible for the payment of all State Income Taxes imposed upon or attributable to KMC or any of its Affiliates (other than State Income Taxes owing to Combined Jurisdictions). KMC and the members of the KMC Group shall indemnify PKS and all PKS Affiliates for any such Taxes. (d) Except as otherwise provided herein, for each taxable period (or portion thereof) ending on or before (or each taxable period including) the Distribution Date, PKS shall be solely responsible for the payment of all State Income Taxes imposed upon or attributable to PKS or any of its Affiliates (other than State Income Taxes owing to Combined Jurisdictions). PKS and the members of the PKS Group shall indemnify all members of the KMC Group for any such Taxes. (e) If a deficiency or refund in a Combined State Income Tax Liability is subsequently proposed or determined, for purposes of this Section 3.3, it shall be assumed for tax years prior to Taxable Year 1999 that (A) any allocation of the Combined State Income Tax Liability made prior to the date of this Agreement between the Parties was consistent with this Section 3.3 and (B) any obligations between the Parties in respect of such allocation have been fully satisfied. Any increase or decrease in Combined State Income Tax Liability, to the extent that it reflects a percentage settlement of multiple proposed deficiencies or overpayments, shall be allocated between the groups in proportion to the manner in which the settled deficiencies or overpayments would have been allocated if settled for the full amount of such deficiencies or overpayments. (f) Notwithstanding anything contained in this Article III to the contrary, in the event that a state Final Determination results in a Combined Group where a Combined State Income Tax Return was not filed as the original Tax Return, and if such combination of entities results in a greater State Income Tax liability than if such entities had not been combined, then neither the PKS Group nor the KMC Group shall be allocated any lesser amount of the Combined State Income Tax Liability resulting from such state Final Determination than such group's "Non-Combined Liability". Each group's "Non-Combined Liability" shall equal the aggregate amount of State Income Tax that all members of such group would have paid to such state for such year had such members not been combined but taking into account all other adjustments to Tax Items reflected in the state Final Determination as if included in the original Tax Returns filed in such state for such year. (g) If a Tax Return or Final Determination consists of or involves a member of the Level 3 Group and a member of the KMC Group (not including members of the PKS Group), all Taxes allocated to the "Kiewit Group" as defined in the PKS/Level 3 Tax Sharing Agreement shall be allocated to the KMC Group pursuant to this Agreement. 11 12 Section 3.4.

(a) Except as provided in Section 3.4(b), for each taxable period ending on or before (or each taxable period including) the Distribution Date, PKS and its Affiliates shall be solely responsible for the payment of (and shall indemnify and hold KMC and its Affiliates harmless from) all Transfer Taxes or Other Taxes imposed on PKS or any PKS Affiliate.

(b) In the event that a Transfer Tax or Other Tax arises from a transaction between PKS or any PKS Affiliate on the one hand, and KMC or any KMC Affiliate, on the other hand, the recipient of property or service in such transaction shall be liable for payment of (and shall indemnify and hold the other Party and its Affiliates harmless from) all such Transfer Taxes or Other Taxes. Section 3.5. Split-Off Taxes.

KMC shall make such payment no later than 10 business days after written notice from PKS of a Final Determination with respect to any PKS Shareholder Tax Indemnity Payment, which notice shall be accompanied by a computation of the amounts due. PKS shall return to KMC any amounts paid to PKS for Taxes and related costs and expenses under this Section 4.2 in connection with a judicial decision (that is not a Final Determination) to the extent such amounts, pursuant to a subsequent Final Determination, are returned by a Taxing Authority to PKS.

If it is determined that there are one or more representations, statements or facts contained in the Statement of Facts or the Ruling Request pertaining to both KMC or its Affiliates and PKS or its Affiliates and such representations, statements or facts are determined to be inaccurate or incomplete as to both, then each Party shall bear and be responsible for (and indemnify the other Party for) its share of Taxes, costs and liabilities or other payments caused by such inaccurate or incomplete facts, representations or statements. For purposes of this Section 4.4, a Party's share of such Taxes, costs and liabilities or other payments shall be determined under Article 6 and shall be based on such Party's relative fault in connection with the inaccurate or incomplete facts, representations or statements. Section 4.5. Breach.

In addition, each Party shall make its employees and facilities available on a mutually convenient basis to facilitate such cooperation. (b) Each Party shall provide prompt notice to the other Party of any pending or threatened Tax controversy, including, without limitation, any audit, any protest to any Taxing Authority or any litigation in Tax Court or any other court of competent jurisdiction (a "Tax Controversy"), that (i) relates to a Tax or Tax Attribute of the other Party or (ii) could give rise to the liability of the other Party to make a payment pursuant to this Agreement (both clauses (i) and (ii) of this Section 5.1(b) constituting a "Liability Issue" of the other Party). PKS and KMC shall promptly furnish each other copies of any inquiries or requests for information or other correspondence from any Taxing Authority or any other administrative, judicial, or other governmental authority concerning any such Liability Issue. Without limiting the generality of the foregoing, PKS and KMC, as the case may be, shall each promptly furnish to the other upon receipt of a copy of any RAR or similar report, notice of proposed adjustment, or notice of deficiency received by PKS or any PKS Affiliate or by KMC or any KMC Affiliate, as the case may be, and, if requested, all other documents relating to any Liability Issue of the other Party.

Upon request by PKS, KMC agrees to provide such documents or information to PKS. Neither Party shall be liable to the other Party (for amounts other than the Tax) for failing to maintain the documents described in this Section 5.1(c), to the extent such Party exercises the same care in maintaining its own similar documents. 18 19 Section 5.2. Contest Provisions. In addition to the provisions of Section 5.1: (a) PKS shall control the handling of and may settle any Tax Controversy (i) involving a Tax Return of the Consolidated Group or a Combined Return or (ii) potentially affecting PKS or any of its Affiliates; provided, however, KMC shall pay upon request reasonable fees to PKS for handling KMC Liability Issues. At its election, KMC may at its sole cost participate in any such proceedings to the extent the proceedings relate to a KMC Liability Issue. The participation rights described in the previous sentence shall include participation in all conferences, meetings or proceedings with any Taxing Authority, the subject matter of which includes the KMC Liability Issue and participation in the preparation of documentation, protests, memoranda of fact and law and briefs with respect to the KMC Liability Issue. (b) KMC shall control (and may settle) any Tax Controversy pertaining solely to KMC but only if such controversy does not involve or relate to a Consolidated Group or Combined Return. PKS shall control (and may settle) any Tax Controversy pertaining to PKS or its Affiliates. (c) In the event that any Taxing Authority proposes that members of one Party's group be included in a unitary, combined or consolidated return with members of the other Party's group with respect to a Tax Return that was not filed as a Combined Return, such Tax Return shall be treated as a Combined Return subject to the provisions of Section 5.2(a) for purposes of determining control of such Tax Controversy. (d) In the event of any Tax Controversy described in Section 5.2(a), PKS (or its Affiliates) in its sole and absolute discretion shall have the right to extend the applicable statue of limitations.

In the event of any dispute or disagreement relating to this Agreement, including, without limitation, any dispute or disagreement with respect to the calculation or allocation of liability for Taxes or Tax Attributes hereunder, the manner of preparing any Tax Return or the meaning of any provision in this Agreement, senior management of the Parties shall negotiate in good faith and attempt to resolve the dispute or disagreement. Section 6.2. Arbitration. In the event that senior management is unable to resolve any dispute or disagreement pursuant to Section 6.1, and such matter is not a matter that, under the terms of this Agreement, is to be determined in the sole and absolute discretion of a particular Party, the Parties shall submit the matter to an arbitration panel. The arbitration panel shall be composed of three members: PKS and KMC shall each appoint one member (who shall not be an employee, officer or director, professional consultant (including, without limitation, outside attorney or accountant) or otherwise related to the appointing party) within 15 days after the matter 19 20 has been submitted to arbitration. If either Party fails to appoint its arbitrator within such 15 day period, the other Party may apply to the American Arbitration Association (the "AAA") to appoint an arbitrator on behalf of the Party that has failed to appoint its arbitrator. The two arbitrators appointed by or on behalf of the Parties shall jointly appoint a third arbitrator who shall chair the arbitration panel. If the two arbitrators cannot agree on a third arbitrator, the third arbitrator shall be appointed by the AAA. The arbitration proceedings shall take place in Chicago, Illinois, and shall be conducted in accordance with the Commercial Arbitration Rules of the AAA. The decision of the arbitration panel with respect to such dispute or disagreement shall be final and binding on the Parties hereunder. All expenses of such arbitration proceedings shall be allocated between PKS and KMC in proportion to each Party's liability with respect to the issue submitted to arbitration. Section 6.3. Timing of Payments. All amounts determined pursuant to Sections 6.1 or 6.2 to be payable by one Party to the other shall be due and payable on or before the date that is 10 business days after the determination that such amount is payable.

Upon payment of any Taxes with respect to which a Party is entitled to receive indemnification hereunder, such receiving Party (the "Indemnified Party") shall send the other Party (the "Indemnifying Party") a notice accompanied by evidence of payment and a statement detailing the Taxes paid and describing in reasonable detail the particular facts relating thereto. Unless a different deadline is expressly provided herein, the Indemnifying Party shall (or shall cause one or more of its Affiliates to) remit payment for Taxes for which the Indemnifying Party is liable hereunder to the Indemnified Party (or one or more of its Affiliates) no later than 30 business days after such notice is sent to the Indemnifying Party. Unless otherwise provided herein, all other payments between the Parties shall be due and payable on or before the date that is 30 business days after notice requesting such payment is sent to the other Party. Section 7.2. Net of Tax Benefits and Detriments. If any Indemnified Party realizes a Tax Benefit or a Tax Detriment by reason of having incurred any Tax or other amount for which such Indemnified Party is entitled to receive indemnification hereunder (including a Tax Detriment realized by reason of having received an indemnity payment hereunder with respect to such Tax), then such Indemnified Party shall pay to the Indemnifying Party an amount equal to the Tax Benefit, or such Indemnifying Party shall pay to such Indemnified Party an additional amount equal to the Tax Detriment (taking into account any Tax Detriment resulting from the receipt of such additional amounts), as the case may be. In the event that, subsequent to such payment, any portion of such Tax Benefit is disallowed or any portion of such Tax Detriment is refunded, the amount paid by one Party to the other with respect to that portion of the Tax Benefit or Tax Detriment shall be repaid to the other Party. The principles of this Section 7.2 apply equally to nonindemnity payments made between the Parties. Section 7.3. Characterization of Payments. The Parties agree to treat, and to cause their respective Affiliates to treat, where appropriate (i) any payment (by one Party or its Affiliates to the other Party or its Affiliates) required by this Agreement (other than a payment described in Section 7.4 or reasonable fees described in Section 5.2(a)) as either a contribution by PKS to KMC 20 21 or a distribution by KMC to PKS, as the case may be, occurring immediately prior to the Split-Off and (ii) any payment of interest or Taxes (other than federal Income Taxes) by or to a Taxing Authority as taxable or deductible, as the case may be, to the Party entitled under this Agreement to retain such payment or required under this Agreement to make such payment, in either case, except as otherwise mandated by applicable law; provided, however, that in the event it is determined as a result of a Final Determination that any such treatment is not permissible, the payment between the Parties (including any indemnification payment described in Section 7.2) shall be adjusted to place the Parties in the same after-Tax position they would have been in had such Final Determination not occurred. To the extent the Parties cannot be placed in the same after-Tax position, the payment between the Parties shall be adjusted so that each Party bears 50% of any Tax Detriment resulting from such Final Determination. Section 7.4. Interest on Overdue Payments. Any payment that is required to be made pursuant to this Agreement (i) by KMC (or a KMC Affiliate) to PKS (or a PKS Affiliate) or (ii) by PKS (or a PKS Affiliate) to KMC (or a KMC Affiliate), that is not made on or prior to the date that such payment is required to be made pursuant to this Agreement shall thereafter bear interest at the rate established for underpayments pursuant to Section 6621(a)(2) of the Code plus three (3) percentage points, compounded daily.

Section 7.11. Legal Enforceability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of the prohibition or unenforceability without invalidating the remaining provisions.
