(c) Notwithstanding Section 2.03(a) or (b), if a Transaction Tax would otherwise be allocated under both Section 2.03(a) and (b), then such Transaction Tax shall be allocated between the Parties in proportion to the relative degrees of fault of the members of the Alcon Group (and such members’ Affiliates and, if applicable, counterparties) and the members of the Novartis Group (and such members’ Affiliates and, if applicable, counterparties).

(d) If a Transaction Tax is not otherwise allocated under this Section 2.03, then such Transaction Tax shall be allocated to Novartis.

(e) Notwithstanding any other provision of this Agreement, if Transaction Taxes are incurred and, as a result of such Transaction Taxes, any member of the Novartis Group or the Alcon Group actually realizes a Tax Benefit, then the Parties shall make appropriate payments to share the Tax Benefit in the same manner as the

Taxes were allocated pursuant to this Agreement (provided that no Tax shall be considered to be allocated to a Party for purposes of computing a payment under this Section 2.03(e) to the extent such other Party owes but has not yet paid any amount in respect of such Tax).

SECTION 2.04. Allocation of Transfer Taxes. Transfer Taxes that are value-added Taxes: (a) of the Alcon Group shall be allocated to Alcon and (b) of the Novartis Group shall be allocated to Novartis. All Transfer Taxes other than value-added Taxes shall be allocated to Novartis.

Novartis and Alcon shall use Commercially Reasonable Efforts to cooperate in determining whether Ordinary Taxes of the Novartis Group and Alcon Group are attributable to the Alcon Business.

(b) Notwithstanding the foregoing:

(i) Ordinary Taxes of the Novartis Group and Alcon Group for Post-Separation Periods that are attributable to any Wrong Pocket Asset or Delayed Interest shall be allocated in accordance with Section 2.06(a)(i) until such time that such asset or interest is transferred to its ultimate owner in accordance with the Separation Agreement, and such Taxes shall be determined on a “with and without” basis; and

(ii) Ordinary Taxes arising as a result of any action by Alcon or its Affiliates described in Section 4.08 shall be allocated to Alcon.

(c) With respect to each Alcon Transferring Entity in a Global Share Transfer Jurisdiction, Novartis shall cause the applicable Alcon Share Transferor to indemnify the applicable Alcon Share Transferee for any Ordinary Taxes allocated to Novartis with respect to such Alcon Transferring Entity under this Section 2.06 that Novartis would be required to indemnify pursuant to Section 2.02 (subject to the limitations in Section 2.07).

SECTION 2.07. Limitation on Indemnification of Ordinary Taxes. Notwithstanding any other provision in this Agreement to the contrary:

(a) Neither Novartis nor Alcon shall be required to indemnify or hold harmless Alcon and its Affiliates or Novartis and its Affiliates for any Ordinary Taxes pursuant to Section 2.01 or Section 2.02, respectively, in each case for any individual item of Ordinary Taxes that does not exceed $10,000.

(b) The provisions of Section 2.07(a) shall not apply to: (i) Ordinary Taxes attributable to any Wrong Pocket Asset or Delayed Interest or (ii) Ordinary Taxes which are not yet due and payable (taking into account any extensions) as of the Separation Date.

SECTION 2.08. Refunds and Credits. Subject to and in accordance with Schedule A, if Novartis, Alcon or any of their respective Affiliates receives a refund of a Tax for which the other Party is liable (in whole or in part) under this Agreement (a “Refund Recipient”), such Refund Recipient shall pay to the other Party, within 30 days of receipt of such refund, an amount equal to the product of (a) such refund, net of any Taxes and reasonable out-of-pocket expenses incurred in connection with the receipt of such refund, multiplied by (b) the percentage of such Tax for which the other Party is liable under this Agreement (reduced to the extent such other Party owes but has not yet paid any amount in respect of such Tax under this Agreement). If a Party would be a Refund Recipient but for the fact that it elected to apply a refund to which it would

otherwise have been entitled against a Tax liability arising in a subsequent taxable period, then for purposes of the immediately preceding sentence, such Party shall be treated as a Refund Recipient and the economic benefit of so applying the refund shall be treated as a refund, and such Party shall be treated as receiving such refund on the due date of the Tax Return to which such refund is applied to reduce the subsequent Tax liability. If a Refund Recipient pays an amount to the other Party in respect of a refund under this Section 2.08 and such refund is subsequently disallowed or reduced by the relevant Taxing Authority, then such other Party shall repay such amount (or the relevant portion thereof, determined in accordance with the principles of this Section 2.08) to the Refund Recipient, net of any Taxes and reasonable out-of-pocket expenses incurred in connection with the receipt and repayment of such amount.

SECTION 3.03. Method of Preparing Tax Returns. To the extent that the Tax Return Preparer is required to prepare a Tax Return that is described in Section 3.01(a)(i) or that directly relates to (i) Taxes or related amounts for which the other Party is responsible under this Agreement, (ii) any Tax Benefit to which such other Party is entitled under this Agreement or (iii) matters affecting a Tax Return that such other Party is required to prepare (or cause to be prepared) under Section 3.01 or Section 3.02:

(a) the Tax Return Preparer shall prepare (or cause to be prepared) such Tax Return or the relevant portions thereof on a basis consistent with past practice (except as required by Applicable Law or as determined in good faith by the Tax Return Preparer), and the Tax Return Preparer shall notify the other Party of any such portions not prepared on a basis consistent with past practice;

(b) the Tax Return Preparer shall, upon request, provide the other Party access to such Tax Return or relevant portions thereof, all related workpapers and such additional information as the other Party may reasonably request at least thirty (30) days prior to the due date (including any valid extensions) for filing such Tax Return and shall consider in good faith such other Party’s reasonable comments; and

Section 3.04. Information Packages.

with back-up calculations (including any applicable back-up calculations described on any of the Schedules that comprise Schedule A).

The Tax Return Preparer shall timely pay (or cause to be timely paid) to the relevant Taxing Authority any Taxes shown as due on any Tax Returns that it is required to prepare or cause to be prepared under Section 3.01, without regard to whether it has received the payment described in the immediately preceding sentence. The obligation to make payments to the relevant Taxing Authority or failure to give notice under this Section 3.05 shall not affect the Tax Return Preparer’s right, if any, to be indemnified or otherwise receive payments with respect to such Taxes under this Agreement, except to the extent that any such failure to give notice has actually prejudiced the other Party.

(a) all Representations made by it or its Affiliates are true, correct and complete; and

(b) it knows of no fact, and has no plan or intention to take or fail to take any action, if it knows or reasonably should expect, after consultation with a Tax Advisor, that such fact, action or failure to act (i) is inconsistent with the Representations given and other information provided by it or its Affiliates in connection with any

Transaction Ruling or Opinion, (ii) is inconsistent with the qualification of any applicable step of the Transactions for its Intended Tax Treatment or (iii) could adversely affect the issuance, effectiveness or validity of any Transaction Ruling or Opinion.

(b) Except as otherwise expressly required or permitted by the Transaction Documents, after the Effective Time neither Party shall take or fail to take, or cause or permit its respective Affiliates to take or fail to take, any action, if such action or failure to act (i) would be inconsistent with the Representations given and other information provided by it or its Affiliates in connection with any Transaction Ruling or Opinion, (ii) would be inconsistent with the qualification of any applicable step of the Transactions for its Intended Tax Treatment or (iii) could adversely affect the issuance, effectiveness or validity of any Transaction Ruling or Opinion.

(c) For purposes of this Agreement, “Unqualified Tax Opinion” means an unqualified “will” opinion of a Tax Advisor, reasonably acceptable to Novartis, that permits reliance by Novartis. The Tax Advisor, in issuing its opinion, shall be permitted to rely on the validity and correctness, as of the date given, of any previously issued Opinion, Unqualified Tax Opinions and Rulings, unless such reliance would be unreasonable under the circumstances, and shall assume that the applicable steps of the Transactions would have qualified for the Intended Tax Treatment if the action in question did not occur.

Subject to Section 4.05(e), if Alcon notifies Novartis that it desires to take a Restricted Action and seeks Satisfactory Guidance for purposes of Section 4.04, Novartis, at the request of Alcon, shall use Commercially Reasonable Efforts to expeditiously obtain, or assist Alcon in obtaining, such Satisfactory Guidance.

Alcon, at the request of Novartis, shall use Commercially Reasonable Efforts to expeditiously obtain, or assist Novartis in obtaining, any such Ruling, other guidance or opinion; provided, however, that Alcon shall not be required to make any representation or covenant that it does not reasonably believe is (and will continue to be) true, accurate and consistent with historical facts. Novartis shall reimburse Alcon for all reasonable out-of-pocket costs and expenses incurred by Alcon or any of its Affiliates in obtaining any such Ruling, other guidance or opinion requested by Novartis within twenty (20) days after receiving an invoice from Alcon therefor.

(d) Pre-Separation Rulings. Novartis and Alcon shall, and shall cause the applicable members of the Novartis Group and Alcon Group, respectively, to, cooperate on a basis consistent with past practice with respect to any request for a ruling from a Tax Authority or advance agreement or other similar proceeding with a Tax Authority that remains pending at the time of the Distribution and the resolution of which is reasonably expected to affect Taxes, or otherwise require the cooperation, of both Novartis (or any other member of the Novartis Group), on the one hand, and Alcon (or any other member of the Alcon Group), on the other hand.

(e) Limitations on Seeking Rulings. Notwithstanding anything herein to the contrary, Alcon shall not seek a ruling from any Tax Authority with respect to a Pre-Separation Period (whether or not relating to the Transactions), and Novartis shall not be required to obtain or assist in obtaining any such ruling, if Novartis determines that there is a reasonable possibility that such action could have an adverse impact on Novartis or any of its Affiliates.

Procedural Matters

SECTION 6.01. Tax Contests. (a) Novartis or Alcon, as applicable, shall, within thirty (30) 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 (or refund entitlement) under this Agreement, notify such other Party of such Tax Contest and thereafter promptly forward or make available to such other Party copies of notices and communications relating to the relevant portions of such Tax Contest (the Party so required to notify such other Party, the “Notifying Party”). Notwithstanding the preceding sentence, if the applicable Tax Authority requests a response, or other action is required, with respect to such Tax Contest within thirty (30) days of the Notifying Party becoming aware of such Tax Contest, the Notifying Party shall notify the other Party of such Tax Contest as soon as possible following the Notifying Party becoming aware of such Tax Contest. A failure by a Party to give notice as provided in this Section 6.01(a) (or to promptly forward any such notices or communications) shall not relieve the other Party’s indemnification obligations under this Agreement, except to the extent that such other Party shall have been actually prejudiced by such failure.

(b) With respect to any Tax Contest Novartis and Alcon are aware of as of the date of this Agreement, which Tax Contests are identified on Exhibit 2 hereto, Novartis shall have the right to control the conduct and settlement of such Tax Contest. With respect to any other Tax Contest other than a Transaction Tax Contest, (i) Novartis

shall have the exclusive right to control the conduct and settlement of any Tax Contest of (A) any member of the Novartis Group and (B) to the extent such Tax Contest relates to a Novartis Consolidated Return, any member of the Alcon Group, and (ii) Alcon shall have the exclusive right to control the conduct and settlement of any other Tax Contest of any member of the Alcon Group. Notwithstanding the foregoing, if the conduct or settlement of any portion or aspect of any such Tax Contest could reasonably be expected to cause the other Party to have an indemnification obligation (or refund entitlement) under this Agreement, then (i) such other Party shall have the right to share joint control over the conduct and settlement of such portion or aspect and (ii) whether or not such other Party exercises that right, Novartis or Alcon, as applicable, shall not accept or enter into any settlement without the prior written consent of such other Party (not to be unreasonably withheld, conditioned or delayed).

(c) Novartis and Alcon shall have the right to control jointly the conduct and settlement of any Transaction Tax Contest. Notwithstanding the foregoing, Novartis shall be entitled to control exclusively the conduct and settlement of any Transaction Tax Contest if Novartis notifies Alcon that (notwithstanding the rights and obligations of the Parties under this Agreement) Novartis agrees to pay (and indemnify Alcon 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 prior written consent of the other Party (not to be unreasonably withheld, conditioned or delayed), (ii) both Parties shall have a right to review and consent to (not to be unreasonably withheld, conditioned or delayed) any correspondence or filings to be submitted to any Tax Authority with respect to such Tax Contest (or the relevant portion or aspect thereof), (iii) both Parties shall have the right to attend any formally scheduled meetings with any Tax Authority or hearings or proceedings before any judicial authority, in each case with respect to such Tax Contest (or the relevant portion or aspect thereof) and (iv) in the event the Tax Contest relates to a Tax Return for which Novartis is the Tax Return Preparer, Alcon shall not consult or otherwise retain any Tax counsel, accountant or other advisor in connection with such Tax Contest unless such Person is a Tax Advisor reasonably acceptable to Novartis.

(e) All reasonable costs, expenses and fees (including legal, accounting and other advisory and court fees) incurred after the Distribution in the course of conducting any Tax Contest, shall be borne by the Parties in the same manner as the Taxes that are the subject of such Tax Contest are allocated between the Parties pursuant to this Agreement.

SECTION 6.02. Cooperation. Novartis and Alcon shall, and shall cause their respective Affiliates to, cooperate fully with all reasonable requests from the other Party in connection with matters covered by this Agreement, including the preparation and filing of Tax Returns, the calculation of Taxes, the determination of the proper financial accounting treatment of Tax items and the conduct and settlement of Tax Contests. Such cooperation shall include (a) the execution of any document that may be necessary or reasonably helpful in connection with the preparation and filing of Tax Returns, the conduct and settlement of Tax Contests or obtaining any Satisfactory Guidance in accordance with this Agreement and (b) compliance with Clause 17 of the Separation Agreement (provided, however, that Books and Records relating to Taxes shall be retained by the relevant Group until the expiration of the relevant statute of limitations (including extensions)).

SECTION 6.03. Indemnification Claims and Payments. (a) A Party shall be entitled to make a claim for indemnification with respect to Taxes under this Agreement when such Party determines that it or one of its Affiliates is entitled to such payment and is able to calculate with reasonable accuracy the amount of such payment. Except as otherwise provided in Section 3.05, such Party shall provide to the other Party notice of such claim within sixty (60) Business Days after the first date on which it so becomes entitled to make such claim. Such notice shall include a description of such claim and a detailed calculation of the amount claimed. Such notified Party shall make the claimed payment to the notifying Party within sixty (60) days after receiving such notice, unless such notified Party reasonably disputes its liability for, or the amount of, such payment.

(b) Notwithstanding Section 6.03(a), with respect to any claim for payment with respect to Taxes that are the subject of a Tax Contest, the Party seeking indemnification (the “Indemnified Party”) shall not be entitled to make a claim for payment until there has been a Determination with respect to such Taxes, provided, however, that if the Indemnified Party is able to pay a reasonable estimate or agreed amount of such Taxes or other commercially reasonable amount (such amount, the “Deposit Amount”) to the applicable Tax Authority and the payment of such Deposit Amount would suspend or avoid the imposition or accrual of interest or penalties with respect to such Taxes, unless both Parties agree otherwise, the other Party (the “Indemnifying Party”) shall pay the Deposit Amount to the Indemnified Party promptly after the Indemnified Party is able to determine the Deposit Amount with reasonable accuracy, and, upon receipt of payment from the Indemnifying Party, the Indemnified Party shall promptly remit the Deposit Amount to the applicable Tax Authority.

(c) A failure by a Party to give notice as provided in Section 6.03(a) shall not relieve the other Party’s indemnification or other payment obligations under this

Agreement, if any, except to the extent that such other Party shall have been actually prejudiced by such failure. Nothing in this Section 6.03 shall prejudice a Party’s right to receive payments pursuant to Section 3.05.

(d) The Parties shall cooperate in good faith to determine the manner in which any payments required to be made under this Agreement shall be made, including by providing for any such payments to be made directly between the Parties’ respective subsidiaries.
