(b) Notwithstanding anything in Section 2.08(a) to the contrary, no payments shall be required pursuant to Section 2.08(a) for overpayments shown on any originally filed Income Tax Return for a Pre-Distribution Tax Period (but not including any amended Income Tax Return or claim for refund), unless the overpayment exceeds the amount set forth on Exhibit A, in which case: (A) Baxalta shall be a Refund Recipient to the extent such overpayment is shown on a Baxalta Separate Return but is attributable to the Baxter Business and (B) Baxter shall be a Refund Recipient to the extent such overpayment is shown on a Joint Return or Baxter Separate Return but is attributable to the Baxalta Business, in each case, as determined pursuant to Section 2.06. For the avoidance of doubt, any refund of Income Taxes for a Pre-Distribution Tax Period received pursuant to a Final Determination or other adjustment by a Tax Authority, or pursuant to an amended Tax Return or claim for refund (but not an originally filed Income Tax Return), shall be governed by Section 2.02(b) and Section 2.08(a).

Section 2.09 Carrybacks and Claims for Refund

(a) Baxalta hereby agrees that if a Tax Return of a member of the Baxalta Group for Post-Distribution Tax Period reflects any Tax Attribute, then the applicable member of the Baxalta Group shall elect to to relinquish, waive or otherwise forgo the right to carry back any such Tax Attribute to a Pre-Distribution Tax Period to the extent permissible under applicable Law. Such elections shall include, but not be limited to, the election described in

Treasury Regulation Section 1.1502-21(b)(3)(ii)(B), and any analogous election under state, local, or foreign Income Tax Laws, to waive the carryback of net operating losses or other Tax Attribute for U.S. federal Income Tax purposes.

(b) If, notwithstanding the provisions of Section 2.09(a), Baxalta is required to carryback a Tax Attribute, Baxter shall promptly remit to Baxalta any Tax Benefit that the Baxter Group actually realizes with respect to any such carryback on an “as and when” realized basis.

(c) If Baxalta has a Tax Attribute that must be carried back to any Pre-Distribution Tax Period, Baxalta shall notify Baxter in writing that such Tax Attribute must be carried back. Such notification shall include a description in reasonable detail of the basis for any Tax Benefit and the amount thereof, and a certification by an appropriate officer of Baxalta setting forth Baxalta’s belief (together with supporting analysis) that the Tax treatment of such Tax Attribute is more likely than not correct.

(d) If Baxter pays any amount to Baxalta under Section 2.09(b) and, as a result of a subsequent Final Determination, a Tax Benefit that gave rise to such payment is subsequently disallowed, Baxter shall notify Baxalta of the amount to be repaid to Baxter, and Baxalta shall then repay such amount to Baxter, together with any interest, fines, additions to Tax, penalties or any additional amounts imposed by a Taxing Authority relating thereto.

(e) For purposes of this Agreement, a Tax Benefit shall be deemed to have been realized at the time any actual refund of Taxes is received or applied against other cash Taxes due, or at the time of filing a Tax Return (including a Tax Return relating to estimated Taxes) on which a Tax Item is applied in reduction of cash Taxes that would otherwise be payable.

Section 2.10 Allocation of Earnings and Profits and Tax Attributes.

(a) The allocation of earnings and profits between the Baxter Group and the Baxalta Group, and the Tax basis of the assets and liabilities transferred to Baxalta in connection with the Transactions, shall be determined in accordance with Exhibit C hereof.

(b) All Tax Attributes determined on a consolidated or combined basis for Pre-Distribution Tax Periods shall be allocated to the Baxter Group and Baxalta Group in accordance with the Code and the Treasury Regulations (and any applicable state, local, or non-U.S. law or regulation). Except as provided in Section 2.10(a), Baxter shall reasonably determine the amounts and proper allocation of such Tax Attributes as of the Distribution Date; provided that Baxalta shall be entitled to participate in such determination. Baxter and Baxalta agree to compute their Tax liabilities for Post-Distribution Tax Periods consistent with that determination and allocation and consistent with Exhibit C.

(c) The allocations made under this Section 2.10 shall be revised by Baxter to reflect each subsequent Final Determination that affects such allocations; provided that Baxalta shall be entitled to participate in such determination.

OTHER ADMINISTRATIVE MATTERS

Section 3.01 Responsibility of Preparing Tax Returns.

(a) Except as described in Section 3.01(b), Baxter shall timely prepare (i) any Joint Returns or Separate Returns that are required or permitted to be filed for any Tax Period beginning on or before the Distribution Date (including Straddle Periods), (ii) any Joint Returns or Baxter Separate Returns that are required or permitted to be filed for any Tax Period beginning after the Distribution Date and (iii) any Tax Returns that are set forth on Schedule 3.01(a). If Baxalta is responsible for filing any such Tax Return under Section 3.03(a), Baxter shall, subject to Section 3.01(c), promptly deliver such prepared Tax Return to Baxalta reasonably in advance of the applicable filing deadline.

(b) Baxalta shall timely prepare (i) any Baxalta Separate Returns relating to Non-Income Taxes or Property Taxes that are required or permitted to be filed for any Tax Period beginning on or before the Distribution Date (including Straddle Periods), (ii) any Baxalta Separate Returns that are required or permitted to be filed for any Tax Period beginning after the Distribution Date and (iii) any Tax Returns that are set forth on Schedule 3.01(b). If Baxter is responsible for filing any such Tax Return under Section 3.03(a), Baxalta shall, subject to Section 3.01(c), promptly deliver such prepared Tax Return to Baxter reasonably in advance of the applicable filing deadline.

(c) To the extent that any Tax Return described in Section 3.01(a) or 3.01(b) directly relates to matters for which another Party may have an indemnification obligation to the Tax Return Preparer, or that may give rise to a refund to which that other Party would be entitled under this Agreement, the Tax Return Preparer shall (i) prepare the relevant portions of the Tax Return on a basis consistent with past practice, except (A) as required by applicable Law or to correct any clear error, (B) as a result of changes or elections made on any Joint Return that do not relate primarily to the Baxalta Group or (C) as mutually agreed by the Parties; (ii) notify the other Party of any such portions not prepared on a basis consistent with past practice; (iii) provide the other Party a reasonable opportunity to review the relevant portions of the Tax Return; (iv) consider in good faith any reasonable comments made by the other Party; and (v) use commercially reasonable efforts to incorporate, in the portion of such Tax Return related to the other Party’s potential indemnification obligation (or refund entitlement), any reasonable comments made by the other Party relating to the Tax Return Preparer’s compliance with clause (i). The Parties shall attempt in good faith to resolve any issues arising out of the review of any such Tax Return.

Section 3.02 Information Packages. Each Party (i) shall provide to the other Party (in the format reasonably determined by the other Party) all information and assistance requested by the other Party as reasonably necessary to prepare any Tax Return described in Section 3.01(a) or Section 3.01(b) on a timely basis consistent with the current practices of the Xxxxxx Group in preparing Tax Returns and (ii) in so providing such information and assistance, shall use any systems and third party service providers as are consistent with the current practices of the Xxxxxx Group in preparing Tax Returns.

Section 3.03 Filing of Tax Returns and Payment of Taxes.

(a) Each Party shall execute and timely file each Tax Return that it is responsible for filing under applicable Law and shall timely pay to the relevant Taxing Authority any amount shown as due on each such Tax Return; provided, that (i) no member of the Baxalta Group shall file any Adjustment Request with respect to a Joint Return, or otherwise alter any Joint Return, without the prior written consent of Baxter, which shall not be unreasonably withheld or delayed. The obligation to make payments pursuant to this Section 3.03(a) shall not affect a Party’s right, if any, to receive payments under Section 3.03(b) or otherwise be indemnified with respect to that Tax liability.

(b) In addition to its obligations under Section 3.01(c), the relevant Tax Return Preparer shall, no later than 5 business days before the due date (including extensions) of any Tax Return described in Section 3.01(a) or (b), notify the other Party of any amount (or any portion of any such amount) shown as due on that Tax Return for which the other Party must indemnify the Tax Return Preparer under this Agreement. The other Party shall pay such amount to the Tax Return Preparer no later than the due date (including extensions) of the relevant Tax Return. A failure by an Indemnitee to give notice as provided in this Section 3.03(b) shall not relieve the Indemnifying Party’s indemnification obligations under this Agreement, except to the extent that the Indemnifying Party shall have been actually prejudiced by such failure.

Section 3.04 Tax Contests

(a) Baxter or Baxalta, as applicable, shall, within 10 business days of becoming aware of any Tax Contest (including a Transaction Tax Contest) that could reasonably be expected to cause the other Party to have an indemnification obligation under this Agreement, notify the other Party of such Tax Contest and thereafter promptly forward or make available to the Indemnifying Party copies of notices and communications relating to the relevant portions of such Tax Contest. A failure by an Indemnitee to give notice as provided in this Section 3.04(a) (or to promptly forward any such notices or communications) shall not relieve the Indemnifying Party’s indemnification obligations under this Agreement, except to the extent that the Indemnifying Party shall have been actually prejudiced by such failure.

(b) Baxter and Baxalta each shall have the exclusive right to control the conduct and settlement of any Tax Contest, other than a Transaction Tax Contest, relating to any Tax Return that it is responsible for preparing pursuant to Section 3.01. Notwithstanding the foregoing, if the conduct or settlement of any portion or aspect of any such Tax Contest could reasonably be expected to cause a Party to have an indemnification obligation under this Agreement, then (i) the Indemnifying Party shall have the right to share joint control over the conduct and settlement of that portion or aspect and (ii) whether or not the Indemnifying Party exercises that right, the Indemnitee shall not accept or enter into any settlement without the consent of the Indemnifying Party, which shall not be unreasonably withheld or delayed.

(c) Baxter and Baxalta shall have the right to control jointly the conduct and settlement of any Transaction Tax Contest. Notwithstanding the foregoing, Baxter shall be entitled to control exclusively the conduct and settlement of any Transaction Tax Contest if Baxter notifies Baxalta that (notwithstanding the rights and obligations of the Parties under this Agreement) Baxter agrees to pay (and indemnify Baxalta against) any Transaction Taxes resulting from such Transaction Tax Contest.

(d) In any case where the Parties control jointly the conduct and settlement of any Tax Contest (or portion or aspect thereof): (i) neither Party shall accept or enter into any settlement of such Tax Contest (or the relevant portion or aspect thereof) without the consent of the other Party, which shall not be unreasonably withheld or delayed, (ii) both Parties shall have a right to review and consent to, which consent shall not be unreasonably withheld or delayed, any correspondence or filings to be submitted to any Taxing Authority with respect to such Tax Contest (or the relevant portion or aspect thereof) and (iii) both Parties shall have the right to attend any formally scheduled meetings with any Tax Authority or hearings.

Section 4.02 Restrictions on Baxalta.

(a) Baxalta agrees that it will not take or fail to take, or permit any member of the Baxalta Group to take or fail to take, any action where such action or failure to act would be inconsistent with or cause to be untrue any material, information, covenant or representation in any Representation Letters or Tax Opinions/Rulings. Baxalta agrees that it will not take or fail to take, or permit any member of the Baxalta Group to take or fail to take, any action which prevents or could reasonably be expected to prevent (i) the Tax-Free Status, or (ii) any transaction contemplated by the Distribution Agreement which is intended by the parties to be tax-free (including, but not limited to, those transactions which the IRS has ruled qualify for tax-free treatment in the IRS Ruling) from so qualifying, including, in the case of Baxalta, issuing any Baxalta Capital Stock that would prevent the Distribution from qualifying as a tax-free distribution within the meaning of Section 355 of the Code.

(b) Baxalta agrees that, from the date hereof until the first day after the two-year anniversary of the Distribution Date, it will (i) maintain its status as a company engaged in the Active Trade or Business for purposes of Section 355(b)(2) of the Code, (ii) not engage in any transaction that would result in it ceasing to be a company engaged in the Active Trade or Business for purposes of Section 355(b)(2) of the Code, (iii) cause each Baxalta Affiliate whose Active Trade or Business is relied upon in the Tax Opinions/Rulings for purposes of qualifying a transaction as tax-free pursuant to Section 355 of the Code or other Tax Law to maintain its status as a company engaged in such Active Trade or Business for purposes of Code Section 355(b)(2) of the Code and any such other applicable Tax Law, and (iv) not engage in any transaction or permit any Baxalta Affiliate to engage in any transaction that would result in a Baxalta Affiliate described in clause (iii) hereof ceasing to be a company engaged in the relevant Active Trade or Business for purposes of Section 355(b)(2) or such other applicable Tax Law, in each case, taking into account Section 355(b)(3) of the Code for purposes of clauses (i) through (iv) hereof

(v) amend its certificate of incorporation (or other organizational documents), or take any other action, whether through a stockholder vote or otherwise, affecting the voting rights of Baxalta Capital Stock (including, without limitation, through the conversion of one class of Baxalta Capital Stock into another class of Baxalta Capital Stock); or

(vi) take any other action or actions (including any action or transaction that would be reasonably likely to be inconsistent with any representation made in the Representation Letters or the Tax Opinions/Rulings) which in the aggregate (and taking into account any other transactions described in this subparagraph (c)) would be reasonably likely to have the effect of causing or permitting one or more persons (whether or not acting in concert) to acquire directly or indirectly stock representing a Fifty-Percent or Greater Interest in Baxalta or otherwise jeopardize the Tax-Free Status;

unless, prior to taking any such action set forth in the foregoing clauses (i) through (vi), (A) Baxalta shall have requested that Baxter obtain a Ruling in accordance with Section 4.04(b) and (d) of this Agreement to the effect that such transaction will not affect the Tax-Free Status and Baxter shall have received such a Ruling in form and substance reasonably satisfactory to Baxter (and in determining whether a Ruling is reasonably satisfactory, Baxter may consider, among other factors, the appropriateness of any underlying assumptions and management’s representations made in connection with such Ruling), (B) Baxalta shall provide Baxter with an Unqualified Tax Opinion in form and substance reasonably satisfactory to Baxter (and in determining whether an opinion is reasonably satisfactory, Baxter may consider, among other factors, the appropriateness of any underlying assumptions and management’s representations if used as a basis for the opinion and Baxter may determine that no opinion would be acceptable to Baxter) or (C) Baxter shall have waived the requirement to obtain such Ruling or Unqualified Tax Opinion.

(d) Certain Issuances of Baxalta Capital Stock.

Section 4.03 Restrictions on Xxxxxx. Xxxxxx agrees that it will not take or fail to take, or permit any member of the Xxxxxx Group to take or fail to take, any action where such action or failure to act would be inconsistent with or cause to be untrue any material, information, covenant or representation in any Representation Letters or Tax Opinions/Rulings. Baxter agrees that it will not take or fail to take, or permit any member of the Xxxxxx Group to take or fail to take, any action which prevents or could reasonably be expected to prevent (i) the Tax-Free Status, or (ii) any transaction contemplated by the Distribution Agreement which is intended by the parties to be tax-free (including, but not limited to, those transactions which the IRS has ruled qualify for tax-free treatment in the IRS Ruling) from so qualifying, including, in the case of Baxter, issuing any Xxxxxx Capital Stock that would prevent the Distribution from qualifying as a tax-free distribution within the meaning of Section 355 of the Code.

Section 4.04 Procedures Regarding Opinions and Rulings.

(b) Baxter agrees that at the reasonable request of Baxalta pursuant to Section 4.02(c), Baxter shall cooperate with Baxalta and use its reasonable best efforts to seek to obtain, as expeditiously as possible, a Ruling from the IRS or other applicable Tax Authority or an Unqualified Tax Opinion for the purpose of permitting Baxalta to take the Notified Action. Further, in no event shall Baxter be required to file any Ruling Request under this Section 4.04(b) unless Baxalta represents that (i) it has read the Ruling Request, and (ii) all information and representations, if any, relating to any member of the Baxalta Group, contained in the Ruling Request documents are (subject to any qualifications therein) true, correct and complete. Baxalta shall reimburse Baxter for all reasonable costs and expenses incurred by the Baxter Group in obtaining a Ruling or Unqualified Tax Opinion requested by Baxalta within ten Business Days after receiving an invoice from Baxter therefor.

(c) Baxter shall have the right to obtain a Ruling or an Unqualified Tax Opinion at any time in its sole and absolute discretion. If Baxter determines to obtain a Ruling or an Unqualified Tax Opinion, Baxalta shall (and shall cause each Affiliate of Baxalta to) cooperate with Baxter and take any and all actions reasonably requested by Baxter in connection with obtaining the Ruling or Unqualified Tax Opinion (including, without limitation, by making any representation or covenant or providing any materials or information requested by the IRS or Tax Advisor; provided that Baxalta shall not be required to make (or cause any Affiliate of Baxalta to make) any representation or covenant that is inconsistent with historical facts or as to future matters or events over which it has no control). Baxter and Baxalta shall each bear its own costs and expenses in obtaining a Ruling or an Unqualified Tax Opinion requested by Baxter.

(b) Except as otherwise provided in Section 3.03(b), the Indemnifying Party shall make the claimed payment to the Indemnitee within 30 business days after receiving such notice, unless the Indemnifying Party reasonably disputes its liability for, or the amount of, such payment.

(c) A failure by an Indemnitee to give notice as provided in Section 3.03(b) or 5.03(a) shall not relieve the Indemnifying Party’s indemnification obligations under this Agreement, except to the extent that the Indemnifying Party shall have been actually prejudiced by such failure.

(d) Nothing in this Section 5.03 shall prejudice a Party’s right to receive payments pursuant to Section 3.03(b).

Section 5.04 Treatment of Indemnity Payments. In the absence of any change in Tax treatment under the Code or other applicable Tax Law and except as provided in Section 5.02, any payments made by a Company under this Agreement shall be reported for Tax purposes by the payor and the recipient as distributions or capital contributions, as appropriate, occurring immediately before the Distribution (but only to the extent that the payment does not relate to a Tax allocated to the payor in accordance with Section 1552 of the Code or the regulations thereunder or Treasury Regulation Section 1.1502-33(d) (or under corresponding principles of other applicable Tax Laws)) or as payments of an assumed or retained liability.

Section 5.05 Tax Gross-Up. If (i) notwithstanding the manner in which any payment under this Agreement is reported, there is a Final Determination with respect to the Tax liability of a Party as a result of its receipt of a payment pursuant to this Agreement or (ii) any deduction or withholding is required by Law to be made from any payment (other than an interest payment) under this Agreement, such payment shall be appropriately adjusted so that the amount of such payment, reduced by the amount of all Income Taxes payable with respect to the receipt thereof

or the amount of all deduction or withholding required by Law with respect to such payment, as applicable (in each case, taking into account all correlative Tax Benefits resulting from the payment of such Income Taxes), shall equal the amount of the payment which the Party receiving such payment would otherwise be entitled to receive pursuant to this Agreement.

Section 5.06 Dispute Resolution. Notwithstanding Section 6.06, but subject to Section 6.16, any and all disputes between Baxter and Baxalta arising out of any provision of this Agreement shall be resolved through the procedures provided in Article VII of the Distribution Agreement.

A party may change the address for receiving notices under this Agreement by providing written notice of the change of address to the other.

Section 6.13 Severability. If any provision of this Agreement or the application thereof to any Person or circumstance is determined by a court of competent jurisdiction to be invalid, void or unenforceable, the remaining provisions hereof, or the application of such provision to Persons or circumstances or in jurisdictions other than those as to which it has been held invalid or unenforceable, shall remain in full force and effect and shall in no way be affected, impaired or invalidated thereby, so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to either Party. Upon any such determination, any such provision, to the extent determined to be invalid, void or unenforceable, shall be deemed replaced by a provision that such court determines is valid and enforceable and that comes closest to expressing the intention of the invalid, void or unenforceable provision.

Section 6.14 Headings. The article, section and paragraph headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

Section 6.15 Waivers of Default. No failure or delay of either Party (or its Affiliates) in exercising any right or remedy under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such right or power, or any course of conduct, preclude any other or further exercise thereof or the exercise of any other right or power. Waiver by either Party of any default by the other Party of any provision of this Agreement shall not be deemed a waiver by the waiving Party of any subsequent or other default.

Section 6.16 Specific Performance. In the event of any actual or threatened default in, or breach of, any of the terms, conditions and provisions of this Agreement, Baxter shall have the right to specific performance and injunctive or other equitable relief of its rights under this Agreement, in addition to any and all other rights and remedies at law or in equity, and all such rights and remedies shall be cumulative. Baxalta shall not oppose the granting of such relief on the basis that money damages are an adequate remedy. The Parties agree that the remedies at law for any breach or threatened breach hereof, including monetary damages, are inadequate compensation for any loss and that any defense in any action for specific performance that a remedy at law would be adequate is waived. Any requirements for the securing or posting of any bond with such remedy are waived. The Parties acknowledge and agree that the right of specific enforcement is an integral part of this Agreement and without that right, neither Baxter nor Baxalta would have entered into this Agreement.

Section 6.17 Amendments. No provisions of this Agreement shall be deemed waived, amended, supplemented or modified by either Party, unless such waiver, amendment, supplement or modification is in writing and signed by the authorized representative of each Party.

Section 6.18 Compliance by Affiliates. The Parties shall cause their respective Affiliates to comply with this Agreement.

IN WITNESS WHEREOF, the Parties have executed and delivered this Agreement as of the day and year first written above.
