Section 2.3 Rules for Determining from which Business a Tax Item Arises. For purposes of Article II, the following rules shall apply to determine from which Business a Tax Item arises:

(a) General Rule. Except to the extent otherwise provided in this Section 2.3, Tax Items shall be deemed to arise from the operation or ownership of the Business to which such items are most closely related.

(b) Brazil. Tax Items related to Taxes imposed by a Tax Authority in Brazil for a Tax Year shall be deemed to arise from the operation or ownership of the Noble Business and the Paragon Business in the same proportion as the number of Brazilian High Specification Rig Days bears to the number of Brazilian Standard Specification Rig Days, respectively, for such Tax Year.

(c) Mexico. Tax Items related to Taxes imposed on any member of the Noble Group or the Paragon Group (other than Paragon Offshore Contracting GmbH or Noble Mexico Limited) by any Governmental Authority in Mexico with respect to a Pre-Spin Period shall be deemed to arise from the operation or ownership of the Paragon Business; provided, however, that any Taxes resulting from the restructuring or dissolution of any Person listed on Schedule 2.3(c) shall be deemed to arise from the operation or ownership of the Noble Business.

(f) Standard Specification Jurisdictions.

(g) High Specification Jurisdictions. Tax Items related to Taxes imposed by any Governmental Authority in Argentina, Australia, China, Cyprus, Egypt, Israel, Libya, New Zealand, or Saudi Arabia with respect to a Pre-Spin Period shall be deemed to arise from the operation or ownership of the Noble Business.

(h) Overhead Costs. Tax Items related to overhead costs and expenses that do not directly relate to either Business shall be allocated between the Noble Business and the Paragon Business in a manner that is consistent with the practice of the Groups before the Spin-off Date.

(i) Tax Benefits Arising from Equity Awards. Tax Benefits arising from the vesting or payment of an equity award shall be deemed to arise from the operation or ownership of the Business that received the benefit of the services to which such equity award relates, regardless of whether such equity award is paid in the form of Noble stock, Paragon stock, or other consideration. Schedule 2.3(i) sets forth the allocation of specific equity awards in a manner that the Parties agree is consistent with this Section 2.3(i).

Section 2.4 Special Rules.

(a) Pro Forma Stand-Alone Basis. For purposes of computing Noble Taxes and Paragon Taxes on a pro forma stand-alone basis, Tax Items shall be taken into account:

(ii) by using all applicable elections, accounting methods, and conventions used on the Tax Return on which such Tax Items are actually reported,

(iii) by applying the average Tax rate on such Tax Return, provided, however, if any category of Tax Items is subject to a different rate of Tax than other categories of Tax Items on such Tax Return, the average Tax rate applicable to such category of Tax Items reported on the Tax Return shall apply with respect to such Tax Items, and

(iv) by treating Tax Benefits as used in the order specified under applicable Tax Law or, to the extent that such Tax Law does not specify the order of use, used pro rata.

(b) Allocation in Straddle Periods. For purposes of Section 2.1(b) and Section 2.2(b), Tax Benefits arising during any Tax Year that begins on or before and ends after the Spin-off Date shall be treated as arising during the Pre-Spin Period or the Post-Spin Period based on an interim closing of the books as of and including the day of the Spin-off Date. Notwithstanding the foregoing, Tax Items attributable to any such Tax Year that are calculated on an annualized basis (including depreciation, amortization and depletion deductions) shall be apportioned between the Pre-Spin Period and the Post-Spin Period on a daily pro rata basis.

(c) Differences between Taxes Shown on Joint Return and Taxes Computed on a Pro Forma Stand-Alone Basis. If, without regard to this Section 2.4(c), the sum of Noble Taxes and Paragon Taxes relating to a Joint Return is different from the amount of Tax shown on such Joint Return, then the Tax shown on such Joint Return shall be allocated between the Parties in the same proportion as the amount of Noble Taxes or Paragon Taxes, as appropriate, bears to the sum of Noble Taxes and Paragon Taxes relating to such Joint Return.

If the Preparer agrees, in its sole discretion, to amend such Tax Return, the Preparer shall be entitled to reimbursement from the Non-Preparer for any reasonable third-party costs that are attributable to the Non-Preparer’s request, to the extent those costs exceed $50,000.

(d) Allocation of Tax Items Between Joint Return and Related Separate Return. Notwithstanding Section 3.3(a), if Tax Items are allocated between a Joint Return and any related Separate Return, then the Preparer of such Separate Return shall (and shall cause the members of its Group to) file the related Separate Return in a manner that is consistent with the reporting of such Tax Items on the Joint Return.

For purposes of Section 4.2, (i) the portion of Taxes paid by the Noble Group to a Tax Authority for which Paragon is wholly or partially liable and (ii) the portion of Taxes paid by the Paragon Group to a Tax Authority for which Noble is wholly or partially liable will be determined by assuming that Paragon and Noble, as appropriate, previously paid the amounts specified in Schedule 4.2(c) with respect to Taxes.

(i) If a member of the Noble Group uses a Tax Benefit for which Paragon is entitled to reimbursement pursuant to Section 2.1(b), Noble shall pay to Paragon, within 30 Business Days following the use of such Tax Benefit, an amount equal to the deemed value of such Tax Benefit, as determined in Section 4.2(d)(iv).

Section 4.4 Special Rule for 2013 Brazilian Taxes and Refunds. Notwithstanding any other provision of this Agreement, any additional Tax due to any Tax Authority in Brazil with respect to the 2013 Tax Year shall be the responsibility of Paragon, and Paragon shall reimburse Noble for any such Taxes paid by the Noble Group to any Tax Authority in Brazil.

Section 4.7 Initial Determinations and Subsequent Adjustments. The initial determination of the amount of any payment that one Party is required to make to another under this Agreement shall be made on the basis of the Tax Return as filed, or, if the Tax to which the payment relates is not reported in a Tax Return, on the basis of the amount of Tax initially paid to the Tax Authority. The amounts paid under this Agreement will be redetermined, and additional payments relating to such redetermination will be made, as appropriate, if as a result of an audit by a Tax Authority, an amended Tax Return, an actual or deemed payment under Section 4.2 in excess of the amounts owed thereunder, or for any other reason (i) additional Taxes to which such redetermination relates are subsequently paid, (ii) a refund of such Taxes is received, (iii) the Group to which a Tax Item is allocated changes or (iv) the amount or character of any Tax Item is adjusted or redetermined. Each payment required by the immediately preceding sentence (i) as a result of a payment of additional Taxes will be due 30 Business Days after the date on which the additional Taxes were paid, (ii) as a result of the receipt of a refund will be due 30 Business Days after the refund was received, (iii) as a result of a change in the allocation of a Tax Item will be due 30 Business Days after the date on which the final action resulting in such change is taken by a Tax Authority or either Party or any member of its Group or (iv) as a result of an adjustment or redetermination of the amount or character of a Tax Item will be due 30 Business Days after the date on which the final action resulting in such adjustment or redetermination is taken by a Tax Authority or either Party or any member of its Group.

Section 4.8 Interest on Late Payments. Payments pursuant to this Agreement that are not made by the date prescribed in this Agreement or, if no such date is prescribed, within 30 Business Days after written demand for payment is made (the “Due Date”) shall bear interest for the period from and including the date immediately following the Due Date through and including the date of payment at a per annum rate fixed at the Prime Rate plus 2% per annum, subject to any maximum amount permitted by applicable Law, on the Due Date (or, if the Due Date is not a business day, as of 11:00 a.m. New York, NY time on the first business day following the Due Date). Such rate shall be redetermined at the beginning of each calendar quarter following such Due Date. Such interest will be payable at the same time as the payment to which it relates and shall be calculated on the basis of a year of 365 days and the actual number of days for which due.

Section 4.9 Payments by or to Other Group Members. When appropriate under the circumstances to reflect the underlying liability for a Tax or entitlement to a Tax refund or Tax Benefit, a payment which is required to be made by or to Noble or Paragon may be made by or to another member of the Noble Group or the Paragon Group, as appropriate, but nothing in this Section 4.9 shall relieve Noble or Paragon of its obligations under this Agreement.

Section 4.10 Procedural Matters. Any written notice for indemnification delivered to the indemnifying Party in accordance with Section 8.4 shall state the amount due and owing together with a schedule calculating in reasonable detail such amount (and shall include any relevant Tax Records, statement, ▇▇▇▇ or invoice related to such Taxes, costs, expenses or other amounts due and owing). All payments required to be made by one Party to the other Party pursuant to this Article IV shall be made in U.S. Dollars by electronic, same day wire transfer. Payments shall be deemed made when received. If the indemnifying Party fails to make a payment to the indemnified Party within the time period set forth in this Article IV, the indemnifying Party shall pay to the indemnified Party, in addition to interest that accrues pursuant to Section 4.8, any costs or expenses incurred by the indemnified Party to secure such payment or to satisfy the indemnifying Party’s portion of the obligation giving rise to the indemnification payment.

Section 4.11 Tax Consequences of Payments. For all Tax purposes and to the extent permitted by applicable Tax Law, the Parties shall characterize any payment made pursuant to this Agreement in the same manner as if such payment were a capital contribution by Noble to Paragon or a distribution by Paragon to Noble, as the case may be, immediately prior to the Spin-off Date. If any such payment (or portion thereof) causes, directly or indirectly, an increase in the Taxes owed by the recipient (or any of the members of its Group) under one or more applicable Tax Laws through withholding or otherwise, the payor’s payment obligation (or portion thereof) under this Agreement shall be grossed up to take into account any additional Taxes that may be owed by the recipient (or any of the members of its Group) as a result of such payment. In the event that a Tax Authority asserts that Noble’s or Paragon’s treatment of a payment pursuant to this Agreement should be other than as required pursuant to this Section 4.11, Noble or Paragon, as appropriate, shall use its commercially reasonable efforts to contest such assertion.

ARTICLE V

TAX CONTESTS

Section 5.1 Notices. Each Party shall provide prompt notice to the other Party of any pending or threatened Tax Contest of which it becomes aware relating to (i) Taxes for which it may be indemnified by the other Party hereunder, (ii) the qualification of the Spin-off as a Tax-free transaction described under Sections 368(a)(1)(D) and 355 of the Code to Noble, its shareholders (except with respect to cash received in lieu of fractional shares), and Paragon, or (iii) any change in the Tax treatment of the Related Separation Transactions. Such notice shall contain factual information (to the extent known by the notifying Party or its agents or representatives) describing any asserted Tax liability in reasonable detail and shall be accompanied by copies of any notice and other documents received from any Tax Authority in

respect of any such matters. If (i) an indemnified Party has knowledge of an asserted Tax liability with respect to a matter for which it is to be indemnified hereunder, (ii) such Party fails to give the indemnifying Party prompt notice of such asserted Tax liability, and (iii) the indemnifying Party has the right, pursuant to Section 5.2, to control the Tax Contest relating to such Tax liability, then (A) if the indemnifying Party is precluded from contesting the asserted Tax liability as a result of the failure to give prompt notice, the indemnifying Party shall have no obligation to indemnify the indemnified Party for any Taxes arising out of such asserted Tax liability and (B) if the indemnifying Party is not precluded from contesting the asserted Tax liability, but such failure to give prompt notice results in a monetary detriment to the indemnifying Party, then any amount which the indemnifying Party is otherwise required to pay the indemnified Party pursuant to this Agreement shall be reduced by the amount of such detriment.

Section 5.2 Control of Tax Contests.

(a) General Rule. Except as otherwise provided in this Section 5.2, the Preparer of any Tax Return shall be the Controlling Party with respect to any Tax Contest involving a Tax reported on such Tax Return.

The Non-Preparer shall be the Controlling Party with respect to that portion of any Tax Contest involving a Tax or Tax Benefit reported on a Joint Return where the Non-Preparer is liable for such Tax or entitled to reimbursement for such Tax Benefit under this Agreement and such Tax or Tax Benefit is separable from all other Taxes or Tax Benefits reported on such Joint Return; provided, however, that Noble shall be the Controlling Party with respect to any Tax Contest involving Separation Tax Items.

(c) Tax Contests Involving Taxes Reported on Certain Brazilian Tax Returns. The Parties shall use all commercially reasonable means to mitigate the assessment of Taxes by any Tax Authority in Brazil and shall share all reasonable third-party costs that are attributable to such mitigation in the same proportion as the number of Brazilian High Specification Rig Days bears to the number of Brazilian Standard Specification Rig Days, respectively, for such Tax Year.

(d) Tax Contests Involving Mexican Tax Receivables. Noble shall be the Controlling Party with respect to any Tax Contest to the extent related to Mexican tax receivables described in Section 4.3. Noble shall reimburse Paragon for any reasonable third-party costs incurred by the Paragon Group in connection with such contest.

(e) Non-Controlling Party Participation Rights. With respect to any Tax Contest involving a Tax for which the Non-Controlling Party may be liable, or a Tax Benefit to which the Non-Controlling Party may be entitled to reimbursement under this Agreement, (i) the Non-Controlling Party shall, at its own cost and expense, be entitled to participate in such Tax Contest, (ii) the Controlling Party shall keep the Non-Controlling Party reasonably informed and consult in good faith with the Non-Controlling Party and its Tax advisors with respect to any issue relating to such Tax Contest, (iii) the Controlling Party shall provide the Non-Controlling Party with copies of all correspondence, notices and other written materials received from any

Tax Authority and shall otherwise keep the Non-Controlling Party and its Tax advisors advised of significant developments in the Tax Contest and of significant communications involving representatives of the Tax Authority, (iv) the Non-Controlling Party may request that the Controlling Party take a position in respect of such Tax Contest, and the Controlling Party shall do so provided that (A) there exists substantial authority for such position (within the meaning of the accuracy-related penalty provisions of Section 6662 of the Code), (B) the adoption of such position would not reasonably be expected to increase the Taxes for which the Controlling Party is liable, or decrease the Tax Benefit for which it is entitled to reimbursement, under this Agreement (unless the Non-Controlling Party agrees to indemnify and hold harmless the Controlling Party from such increase in Taxes or reduction in Tax Benefits), and (C) the Non-Controlling Party agrees to reimburse the Controlling Party for any reasonable third-party costs that are attributable to the Non-Controlling Party’s request, to the extent those costs exceed $50,000, (v) the Controlling Party shall provide the Non-Controlling Party with a copy of any written submission to be sent to a Taxing Authority prior to the submission thereof and shall give good faith consideration to any comments or suggested revisions that the Non-Controlling Party or its Tax advisors may have with respect thereto, and (vi) there will be no settlement, resolution or closing or other agreement with respect thereto without the consent of the Non-Controlling Party, which consent shall not be unreasonably withheld or delayed.

by the Preparer to permit the timely filing of a Joint Return, then, notwithstanding any other provision of this Agreement, the Preparer shall be liable for, and shall indemnify and hold harmless each member of the Non-Preparer’s Group from and against, any penalties, interest or additional amounts in respect of Taxes (but excluding any Taxes underlying such amounts) assessed against any member of either Group by reason of any delay in filing such return.

If the Non-Preparer fails to take, or cause to be taken, any such requested action, the indemnification principles of Section 6.1(a) shall apply with respect to any penalties, interest, or additional amounts in respect of Taxes (but excluding any Taxes underlying such amounts) assessed against any member of either Group by reason of a failure to take any such requested action, to the extent such penalties, interest, or additional amounts in respect of Taxes are directly attributable to the failure to take such action.

At the request of the Controlling Party, the Non-Controlling Party shall take (and shall cause its Subsidiaries to take) any action (e.g., executing a limited power of attorney) that is reasonably necessary in order for the Controlling Party’s Group to handle, settle or conduct the Tax Contest. Each Party shall assist the other Party in taking (or causing to be taken) any remedial actions that are necessary or desirable to minimize the effects of any adjustment made by a Tax Authority. The Controlling Party shall reimburse the Non-Controlling Party for any reasonable out-of-pocket costs and expenses incurred in complying with this Section 6.3(b). The Controlling Party shall have no obligation to indemnify the Non-Controlling Party for any additional Taxes resulting from the Tax Contest, if the Non-Controlling Party fails to provide assistance in accordance with this Section 6.3(b), to the extent such additional Taxes are directly attributable to the Non-Controlling Party’s failure to provide such assistance.

(c) Cooperation. In addition to the obligations enumerated elsewhere in this Article VI, Noble and Paragon shall cooperate (and shall cause their respective Subsidiaries to cooperate) with each other and with each other’s agents and representatives, including their respective accounting firms and legal counsel, in connection with Tax matters, including, making available to each other, as reasonably requested and available, personnel (including officers, employees and agents of the Parties or their Subsidiaries) responsible for preparing, maintaining, and interpreting information and documents relevant to Taxes, and personnel reasonably required as witnesses or for purposes of providing information or documents in connection with any Tax Contest.
