(iv) any Refund of Mallinckrodt Separation Taxes received by any member of the Mallinckrodt Group or the Covidien Group to the extent that liability for such Taxes was actually borne by Mallinckrodt; provided, that, solely for purposes of this Article 2.05(a)(iv), any Refund in respect of a Separation Tax shall be treated first as a Refund of a Mallinckrodt Separation Tax if and only to the extent Mallinckrodt bore such Tax, taking into account the application of Article 2.03, and thereafter as a Refund of a Covidien Separation Tax.

(b) Covidien shall be entitled to all Refunds related to Specified Taxes received by any member of the Mallinckrodt Group or the Covidien Group other than those to which Mallinckrodt is entitled pursuant to Article 2.05(a).

(c) Each Party shall pay to the other Party any Refund received by such Party or any member of such Party’s Group that is allocable to the other Party

pursuant to this Article 2.05 no later than five (5) Business Days after the receipt of such Refund. For purposes of this Article 2.05(c), any Refund that arises as a result of an offset, credit, or other similar benefit in respect of Taxes other than a receipt of cash shall be deemed to be received on the earlier of (i) the date on which a Tax Return is filed claiming such offset, credit, or other similar benefit and (ii) the date on which payment of the Tax which would have otherwise been paid absent such offset, credit, or other similar benefit is due (determined without taking into account any applicable extensions).

2.06 PRIOR AGREEMENTS. Except as set forth in this Agreement and in consideration of the mutual indemnities and other obligations of this Agreement, any and all prior Tax sharing or allocation agreements or practices between any member of the Covidien Group and any member of the Mallinckrodt Group shall be terminated with respect to the Mallinckrodt Group and the Covidien Group as of the Distribution Date.

(c) To the extent that any Tax or Tax-Related Loss is subject to indemnity pursuant to both Articles 5.01(a) and 5.01(b), responsibility for such Tax or Tax-Related Loss shall be shared by Covidien and Mallinckrodt according to relative fault.

5.02 INDEMNIFICATION PAYMENTS.

(a) Except as otherwise provided in this Agreement, if either Party (the “Indemnified Party”) is required to pay to a Taxing Authority a Tax or to another Party an indemnification payment in respect of a Tax that another Party (the “Indemnifying Party”) is liable for under this Agreement, including as the result of a Final Determination, the Indemnified Party shall notify the Indemnifying Party, in writing, of its obligation to pay such Taxes and, in reasonably sufficient detail, its calculation of the amount due by such Indemnifying Party to the Indemnified Party, including any Tax-Related Losses attributable thereto. The Indemnifying Party shall pay such amount, including any Tax-Related Losses attributable thereto, to the Indemnified Party no later than the later of (i) five (5) Business Days prior to the date on which such payment is due to the applicable Taxing Authority or (ii) fifteen (15) Business Days after the receipt of notice from the other Party.

(b) If, as a result of any change or redetermination made with respect to Article 2.01 or 2.02, including, without limitation, pursuant to Article 2.03(b), any amount previously allocated to and borne by one Party pursuant to the provisions of Article II is thereafter allocated to the other Party, then, no later than five (5) Business Days after such change or redetermination, such other Party shall pay to such Party the amount previously borne by such Party which is allocated to such other Party as a result of such change or redetermination.

5.03 PAYMENTS NET OF TAX BENEFITS.

(a) All amounts required to be paid by one Party to another pursuant to this Agreement, the Distribution Agreement or any Ancillary Agreement shall be reduced by the Tax Benefit Amount, if any, with respect to the Indemnified Party or its Subsidiaries in respect of the indemnified liability.

(b) If and to the extent any Tax Benefit Amount arises in respect of an indemnified liability which has not already reduced any payment made to the Indemnified Party or its Subsidiaries pursuant to this Agreement or otherwise been paid to the Indemnifying Party then, no later than five (5) Business Days after the filing of a Tax Return with respect to the applicable taxable period in which such Tax Benefit

Amount arose, such Indemnified Party shall pay to the Indemnifying Party the amount of any such Tax Benefit Amount not previously taken into account. For the avoidance of doubt, in the event that a deduction, credit, loss or other Tax attribute, or any portion thereof, arising as a result of such payment results in a Tax Benefit Amount in a taxable period or portion thereof prior to or later than the taxable period during which such payment is considered to have been made for applicable Tax purposes, then this Article 5.03 shall continue to apply for all taxable periods included in the applicable Tax Benefit Period.

(i) any liability for which Mallinckrodt or any member of the Mallinckrodt Group is required to indemnify Covidien or any member of the Covidien Group pursuant to this Agreement, the Distribution Agreement, or any Ancillary Agreement, or

(ii) any liability for a Tax for which Mallinckrodt or any member of the Mallinckrodt Group is liable pursuant to Articles 2.02(b), 2.02(c), or 2.02(d) of this Agreement (in each case, without regard to Article 2.03),

Mallinckrodt and each member of the Mallinckrodt Group shall, with respect to each Tax Return required to be filed, or actually filed, with respect to each such taxable period, provide to Covidien pro forma copies (the “Pro Forma Returns”) of each such Tax Return prepared in accordance with the principles set forth in the definition of Tax Benefit Amount. Such pro forma Tax Return shall determine the Tax Benefit Amount, if any, realized by Mallinckrodt or any member of the Mallinckrodt Group in respect of such liability or Tax. Mallinckrodt shall deliver such pro forma Tax Returns to Covidien no later than forty-five (45) calendar days following the earlier of the date on which such Tax Return was filed or required to be filed.

(d) If Mallinckrodt fails to provide to Covidien any Pro Forma Return with respect to a liability for which it is required to provide such a return pursuant to Article 5.03(c), then, notwithstanding anything else to the contrary in this Agreement, including the definition of Tax Benefit Amount, the Tax Benefit Amount in respect of such liability shall, if and to the extent such liability is or may potentially be deductible, creditable, or otherwise potentially available to offset or reduce any amount of Taxes in any jurisdiction (as determined in Covidien’s reasonable discretion), for all purposes of this Agreement and each Ancillary Agreement be equal to the product of (a) the absolute value of the amount of such liability and (b) the Mallinckrodt Assumed Tax Rate.

5.04 PAYMENT MECHANICS.

(a) Subject to Article 10.02, all payments under this Agreement shall be made by Covidien directly to Mallinckrodt and by Mallinckrodt directly to Covidien; provided, however, that if the Parties mutually agree with respect to any such

indemnification payment, any member of the Covidien Group, on the one hand, may make such indemnification payment to any member of the Mallinckrodt Group, on the other hand, and vice versa. All indemnification payments shall be treated in the manner described in Article 5.05.

(b) Any late payment made by one Party to another Party pursuant to this Agreement shall be subject to interest at a rate per annum equal to the then effective Prime Rate plus 5% (or the maximum legal rate, whichever is lower), calculated for the actual number of days elapsed, and accrued from the date on which such payment was due up to the date of the actual receipt of payment.

(c) In the case of any payment of Taxes made by a Responsible Party or Indemnified Party pursuant to this Agreement for which such Responsible Party or Indemnified Party, as the case may be, has received a payment from the other Party, such Responsible Party or Indemnified Party shall provide to the other Party a copy of any official government receipt received with respect to the payment of such Taxes to the applicable Taxing Authority (or, if no such official governmental receipts are available, executed bank payment forms or other reasonable evidence of payment).

5.05 TREATMENT OF PAYMENTS. The Parties agree that any payment made among the Parties pursuant to this Agreement shall be treated, to the extent permitted by law, for all United States federal income Tax purposes as either (i) a non-taxable contribution by Covidien to Mallinckrodt, or (ii) a distribution by Mallinckrodt to Covidien, in each case, made immediately prior to the Distribution.

ARTICLE VI

6.01 NOTICE. Each Party shall promptly notify the other Party in writing upon receipt by such Party or any member of its Group of a written communication from any Governmental Entity with respect to any pending or threatened audit, claim, dispute, suit, action, proposed assessment or other proceeding (a “Tax Contest”) concerning any Taxes for which the other Party may be liable pursuant to this Agreement.

6.04 2007 TCE TSA CONTEST INFORMATION UPDATE. Notwithstanding anything to the contrary in this Agreement, Covidien shall (i) provide to Mallinckrodt any factual information Covidien receives from the Audit Management Party regarding any 2007 TCE TSA Tax Contest relating to Taxes for which Mallinckrodt may be liable pursuant to Article 2.02, and (ii) provide notice to Mallinckrodt of any pending or threatened 2007 TCE TSA Tax Contest of which it becomes aware relating to Taxes for which Mallinckrodt may be liable pursuant to Article 2.02 reasonably promptly after receipt of notice pursuant to the 2007 TCE TSA. Such notice shall contain factual information (to the extent known) describing any asserted Tax liability in reasonable detail and shall be accompanied by copies of any notice and other documents received from any Taxing Authority in respect of any such matters. Mallinckrodt shall not have any right to any amount paid to Covidien or any member of the Covidien Group pursuant to the 2007 TCE TSA regardless of whether such payment relates to an amount for which Mallinckrodt is liable pursuant to the terms of this Agreement or any Ancillary Agreement. Mallinckrodt shall take or refrain from taking, and shall cause each member of the Mallinckrodt Group to take or refrain from taking, any and all actions reasonably requested by Covidien that would preserve, exercise, or contravene, as the case may be, Covidien’s rights and obligations under the 2007 TCE TSA.

6.05 OBLIGATION OF CONTINUED NOTICE. During the pendency of any Tax Contest or threatened Tax Contest, other than a 2007 TCE TSA Tax Contest, each of the Parties shall provide prompt notice to the other Party of any written communication received by it or a member of its respective Group from a Taxing Authority regarding any Tax Contest for which it is indemnified by the other Party hereunder or for which it may be required to indemnify the other Party hereunder. Such notice shall attach copies of the pertinent portion of any written communication from a Taxing Authority and contain factual information (to the extent known) describing any asserted Tax liability in reasonable detail and shall be accompanied by copies of any notice and other documents received from any Taxing Authority in respect of any such matters. Such notice shall be provided in a reasonably timely fashion; provided, however, that in the event that timely notice is not provided, a Party shall be relieved of its obligation to indemnify the other Party only to the extent that such delay results in actual increased costs or actual prejudice to such other Party.

6.06 SETTLEMENT RIGHTS. Unless waived by the Parties in writing, in connection with any potential adjustment in a Tax Contest, other than a 2007 TCE TSA Tax Contest, as a result of which adjustment the Non-Controlling Party may reasonably be expected to become liable to make any indemnification payment to the Controlling Party under this Agreement: (i) the Controlling Party shall keep the Non-Controlling Party informed in a timely manner of all actions taken or proposed to be taken by the Controlling Party with respect to such potential adjustment in such Tax Contest; (ii) the Controlling Party shall timely provide the Non-Controlling Party copies of any written materials relating to such potential adjustment in such Tax Contest received from any Tax Authority; (iii) the Controlling Party shall timely provide the Non-Controlling Party with copies of any correspondence or filings submitted to any Tax Authority or judicial authority in connection with such potential adjustment in such Tax Contest; and (iv) the Controlling Party shall defend such Tax Contest diligently and in good faith; provided, however, that nothing in this Article 6.06 shall affect Covidien’s right to control, resolve, settle, or agree to any deficiency, claim, or adjustment proposed, asserted, or assessed in connection with or as a result of any Covidien Controlled Tax Contest, or consent to the resolution, settlement or agreement of any deficiency, claim or adjustment proposed, asserted or assessed in connection with or as a result of any such Mallinckrodt Controlled Tax Contest, in Covidien’s sole and absolute discretion. The failure of the Controlling Party to take any action specified in the preceding sentence with respect to the Non-Controlling Party shall not relieve the Non-Controlling Party of any liability and/or obligation which it may have to the Controlling Party under this Agreement, and in no event shall such failure relieve the Non-Controlling Party from any other liability or obligation which it may have to the Controlling Party.

ARTICLE VII

All fees and expenses of the Preliminary Tax Advisor shall be borne by the Party that engaged such advisor and all of the fees and expenses of the Tax Advisor shall be shared equally by each of the Parties to the Dispute.
