The parties shall file all applicable Tax Returns in accordance with the foregoing sentence and shall not take any Tax position that is inconsistent with the foregoing sentence, in each case, unless

otherwise required by a final determination, within the meaning of Section 1313 of the Code (or similar provisions of state or local Tax Law).

SECTION 1.03 Royalty Payments. During the Royalty Term, royalty payments (the “Royalty Payments”) shall be paid by Purchaser to Holding in accordance with this Section 1.03.

(a) Royalty Rates. The amount of the Royalty Payments shall equal (i) [***] percent ([***]%) of annual worldwide Net Sales of Patented Products up to $[***], (ii) [***] percent ([***]%) of annual worldwide Net Sales of Patented Products above $[***] and up to $[***], (iii) [***] percent ([***]%) of annual worldwide Net Sales of Patented Products above $[***] and up to $[***], and (iv) [***] percent ([***]%) of annual worldwide Net Sales of Patented Products above $[***].

The Royalty Payments payable by Purchaser to Sellers shall be paid on a Product-by-Product and country-by-country basis from the date of the first commercial sale of such Product in such country until the expiration in such country of the last to expire Valid Claim of a Transferred Patent claiming such Product (the “Royalty Term”).

(c) Royalty Report and Payment. During the Royalty Term, no later than [***] after the end of each Calendar Quarter, Purchaser or its Affiliates shall pay to Holding the Royalty Payments payable for such Calendar Quarter and provide a royalty report (the “Royalty Report”) showing:

All payments to be made by Purchaser to Holding under Sections 1.02 and 1.03 shall be made in Dollars and shall be paid by wire transfer in immediately available funds to such bank account in the United States as is designated in writing by Holding from time to time. In computing the Dollar amount of Net Sales of a Patented Product outside the United States, after calculating the Net Sales in the currency of sale, the rate of exchange to be used in such computation shall be the average of the rate of exchange published by Bloomberg Business over the course of the Calendar Quarter in which such sales occurred.

(b) Tax Withholding. Purchaser acknowledges that, absent a change in Applicable Law (for the avoidance of doubt, including the Treaty), its interpretation or practice, after the date hereof, and provided that the Seller timely provides all required and properly completed required tax forms necessary to claim the benefits of a complete exemption from withholding tax, including with respect to Seller’s eligibility under the Convention between the United States and the Netherlands signed on December 18, 1992 (the “Treaty”), it will not deduct or withhold any United States federal income Taxes from the Milestone Payments and Royalty Payments. Purchaser (or any of its Affiliates or agents, as the case may be) shall be entitled to deduct and withhold any Taxes from any other amounts payable pursuant to this Agreement such amounts, if any, as are required under Applicable Law to be so withheld or deducted. To the extent such amounts are so withheld and remitted to the relevant Governmental Entity, such withheld amounts shall be treated for all purpose of this Agreement as having been paid to the Person in respect of whom such withholding was made, and in a timely manner and as promptly as reasonably practicable Purchaser (or any of its Affiliates) shall transmit to Sellers an official Tax certificate or other reasonable evidence of such Tax obligations and supporting calculations, together with proof of payment from the relevant Governmental Entity or other reasonable documentation in support thereof of all amounts deducted and withheld sufficient to enable Sellers to claim such payment of Taxes with the appropriate Governmental Entity. Purchaser and its Affiliates shall provide Sellers with prior written notice of Purchaser’s (or any of its Affiliate’s) intention to withhold, the legal basis therefor and a reasonable opportunity to furnish forms, certificates or other items that would reduce or eliminate such withholding Taxes. Each party agrees to use commercially reasonable efforts and to cooperate with the other party to minimize any anticipated withholding Tax required to be paid under any provision of federal, state, local, or foreign Tax law with respect to the payments made by Purchaser to Sellers or their Affiliates under this Agreement.

(c) Records and Audit. Purchaser shall keep, and shall contractually require that its Affiliates and its Commercial Licensees keep, books and records prepared in accordance with their respective standard accounting procedures and in accordance with GAAP, in each case consistently applied, for the purpose of determining and validating (i) the amount of Royalty Payments due to Holding hereunder, including, without limitation, the calculation of Net Sales in each country where Patented Products are sold, and (ii) whether or not the Milestone Event has occurred. Such books and records will be kept at the principal place of business of Purchaser (or its Affiliates or its licenses, as applicable) and maintained for no less than [***] following the end of the Calendar Year to which they pertain. At the request of Sellers, Purchaser and its Affiliates and its Commercial Licensees shall permit an independent certified public accountant appointed by Sellers and reasonably acceptable to Purchaser (or its Affiliates or Commercial Licensees, as applicable), at reasonable times and upon reasonable notice, to examine those records as may be

necessary to determine, with respect to any Calendar Year ending not more than [***] prior to Sellers’ request, the correctness or completeness of any report or payment pursuant to Sections 1.02 or 1.03. The foregoing right of review may be exercised only [***] per Calendar Year and only once with respect to each such periodic report and payment. Results of any such examination shall be (A) limited to information relating to Patented Products, (B) made available to both Purchaser and Sellers and (C) subject to the confidentiality provisions set forth below. Prior to commencing any examination, the independent certified public accountant shall have agreed in writing to maintain all information learned in confidence, except as necessary to disclose to Purchaser and Sellers the results of such examination, and shall have executed all customary release letters reasonably requested by Purchaser’s independent auditors. Sellers shall bear the full cost of the performance of any such audit, unless such audit discloses a variance to the detriment of Sellers of more than [***] percent ([***]%) from the amount of the original report or Royalty Payment calculation. In such case, Purchaser shall bear the full cost of the performance of such audit. Any underpayments of Royalty Payments or the Milestone Payment shall be paid by Purchaser within [***] of notification of the results of such audit, together with interest at a rate of [***] percent ([***]%) [***] period since the payment due date. Any overpayments of Royalty Payments or Milestone Payment shall be fully creditable by Purchaser against any amounts subsequently payable by Purchaser pursuant to this Agreement or, if no such amounts become payable within [***] after notification of such results, shall be refunded by Sellers to Purchaser or its designee. Purchaser shall contractually require that its Affiliates and their respective Commercial Licensees submit to the exercise of Sellers’ right of audit hereunder.

SECTION 6.05 Procedures Relating to Indemnification for Third Party Claims.

Such notice by the indemnified party shall describe the Third Party Claim in reasonable detail, shall include copies of all material written evidence thereof and shall include the estimated amount (if it is reasonably possible to calculate such amount) of the Losses that have been or may be sustained by the indemnified party. Thereafter, the indemnified party shall deliver to the indemnifying party, promptly after the indemnified party’s receipt thereof, copies of all notices and documents (including court papers) received by the indemnified party relating to the Third Party Claim.

(b) If a Third Party Claim is made against an indemnified party, the indemnifying party shall be entitled to participate in the defense thereof and, if it so chooses, to assume the defense thereof with counsel selected by the indemnifying party (not reasonably objected to by the indemnified party) and the indemnified party shall cooperate in good faith in such defense; provided, however, that the indemnifying party shall not be entitled to assume the defense of any Third Party Claim that (A) involves criminal liability or any admission of wrongdoing, (B) seeks equitable relief or any other non-monetary remedy against the indemnified party or (C) involves any Governmental Entity as a party thereto. If the indemnifying party elects to assume the defense of a Third Party Claim in accordance with this Section 6.05(b), the indemnifying party shall not be liable to the indemnified party for legal expenses subsequently incurred by the indemnified party in connection with the defense thereof; provided, however, that if in the reasonable opinion of outside counsel to the indemnified party (1) a conflict or potential conflict exists between the indemnified party and the indemnifying party that would make separate representation advisable or (2) the indemnified party has legal defenses available to it which are different from or in addition to the defenses available to the indemnifying party, then the indemnified party may retain its own counsel at the expense of the indemnifying party; provided, further, that that indemnifying party shall not be required to pay for more than one such counsel for all indemnified parties in connection with any such Third Party Claim. If the indemnifying party elects to assume the defense of a Third Party Claim in accordance with this Section 6.05(b), the indemnified party shall have the right to participate in the defense thereof and, without limiting the preceding sentence, to employ counsel, at its own cost and expense, separate from the counsel employed by the indemnifying party. The indemnifying party shall be liable for the fees and expenses of counsel employed by the indemnified party for any period during which the indemnifying party has failed to assume the defense thereof in accordance with this Section 6.05(b).

(c) If the indemnifying party so elects to assume the defense of a Third Party Claim in accordance with Section 6.05(b), the indemnified party shall cooperate with the indemnifying party in the defense or prosecution thereof. Such cooperation shall include the retention and (upon the indemnifying party’s request) the provision to the indemnifying party of records and information which are reasonably relevant to such Third Party Claim, and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. If the indemnified party is conducting the defense of any Third Party Claim, the indemnifying party shall cooperate with the indemnified party in the defense or prosecution thereof. Such cooperation shall include the retention and (upon the indemnified party’s request) the provision to the indemnified party of records and information which are reasonably relevant to such Third Party Claim, and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The indemnifying party shall not admit any liability with respect to, or settle, compromise or discharge, any Third Party Claim without the indemnified party’s prior written consent, unless (i) the proposed settlement or disposition involves only the payment of money damages by the indemnifying party for which the indemnified party shall have no liability, (ii) the proposed settlement or disposition does not impose an injunction or other equitable relief upon the indemnified party, (iii) the proposed settlement or disposition does not include any admission of wrongdoing or misconduct and (iv) the indemnified party is fully and unconditionally released from any liability relating to such Third Party Claim. The indemnified party shall not admit any liability with respect to, or settle, compromise or discharge, any Third Party Claim without the indemnifying party’s prior written consent. In the event that a settlement offer solely for monetary damages is made by the applicable Third Party claimant, and the indemnifying party notifies the indemnified party of its willingness to accepts the offer and, subject to the applicable limitations of Section 6.02, pay the amount called for by such offer, and the indemnified party declines to accept such offer, the indemnified party may continue to contest such Third Party claim, free of any participation from the indemnifying party, and the amount of any ultimate liability with respect to such Third Party Claim that the indemnifying party has an obligation to pay hereunder shall be limited to the lesser of (x) the amount of the settlement offer that the indemnified party declined to accept or (y) the aggregate Losses of the indemnified party with respect to such Third Party Claim.

SECTION 6.06 Procedures Related to Indemnification for Other Claims. In the event any indemnified party should have a claim against any indemnifying party under Section 6.01 or 6.02 that does not involve a Third Party Claim being asserted against or sought to be collected from such indemnified party, the indemnified party shall promptly deliver written notice of such claim, in reasonable detail, to the indemnifying party; provided, however, that failure by any indemnified party to so notify the indemnifying party shall not relieve the indemnifying party from any liability which it may have to such indemnified party under Section 6.01 or 6.02, except and only to the extent that the indemnifying party forfeits rights or defenses by reason of such failure or shall have been materially prejudiced as a result of such failure. If the indemnifying party disputes its liability with respect to such claim, the indemnifying party and the indemnified party shall proceed in good faith to negotiate a resolution of such dispute and, if not resolved through negotiations, such dispute shall be resolved by litigation in an appropriate court of competent jurisdiction.

SECTION 6.07 Tax Treatment of Indemnification Payments. For all United States Tax purposes, Purchaser, Sellers and each of their respective Affiliates agree to treat any indemnity payment under this Agreement as an adjustment to the Purchase Price received by Sellers for the transactions contemplated by this Agreement unless a final determination (as defined in Section 1313 of the Code) provides otherwise.

(e) In the event of any Third Party Claim where the Indemnifying Party does not assume the defense of such Third Party Claim, nothing in this Section 7.13 shall prevent the Indemnified Party from impleading the Indemnifying Party or otherwise joining the Indemnifying Party to any litigation relating to such Third Party Claim.
