All of the out-of-pocket expenses of any inspection or audit requested by the Buyer hereunder (including any audits of any Related Parties and the fees and expenses of such independent public accounting firm designated for such purpose) shall be borne solely by the Buyer, unless the independent public accounting firm determines that Royalty Payments previously paid during the period of the audit were underpaid by an amount greater than [***] of the Royalty Payments actually paid during such period, in which case such expenses shall be borne by the Seller. Any such accounting firm shall not disclose the confidential information of the Seller or any such Licensee relating to a Product to the Buyer, except to the extent such disclosure is necessary to determine the correctness of Royalty Payments or otherwise would be included in a Report or a Royalty Report. All information obtained by the Buyer as a result of any such inspection or audit shall be Confidential Information subject to ARTICLE 8. If any audit discloses any underpayments by the Seller to the Buyer, then such underpayment shall be paid by the Seller to the Buyer within [***] of it being so disclosed. If any audit discloses any overpayments by the Seller to the Buyer, then (i) the Seller shall have the right to credit the amount of the overpayment against each subsequent quarterly Royalty Payment due to the Buyer until the overpayment has been fully applied, or (ii) if requested by the Seller in writing, the Buyer shall refund an amount equal to any such remaining overpayment within [***] of receipt of the Seller’s written request.

(a) The Seller shall, at its sole expense, either directly or by causing any Licensee to do so, use Commercially Reasonable Efforts to take such actions (including taking legal action to specifically enforce the applicable terms of any In-License or Out-License), and prepare, execute, deliver and file any and all agreements, documents or instruments which are necessary to diligently prosecute and maintain, and avoid disclaimer or abandonment of, the Patent Rights in the Territory. The Seller shall use Commercially Reasonable Efforts to ensure that all patent applications corresponding to the Patent Rights are diligently prosecuted with the intent to protect all Products in the Territory. In the exercise of its reasonable business discretion, the Seller shall use Commercially Reasonable Efforts to diligently defend or assert the Patent Rights against infringement or interference by any other Persons, and against any claims of invalidity (including any reexamination, inter partes review, opposition, or like proceeding) or unenforceability, including, without limitation, by bringing any legal action for infringement or defending any counterclaim of invalidity or action of a Third Party for declaratory judgment of non-infringement or non-interference, in each case in the Territory. Notwithstanding any other obligation of Seller under this ‎Section 6.5(a), Seller shall (i) timely bring and prosecute infringement actions in response to certifications made under paragraph IV of 21 U.S.C. §355(j)(2)(A)(vii) or §355(b)(2)(A) with respect to any Orange Book Patent, (ii) defend the Orange Book Patents against any claim of invalidity or unenforceability, and (iii) not disclaim or abandon any Orange Book Patent.

(c) The Seller shall promptly inform the Buyer of any infringement by a Third Party of any Patent Right in the Territory of which any of the individuals named in the definition of “Knowledge of the Seller” (or the successors of such Person at the Seller) becomes aware. Without limiting the foregoing, the Seller shall provide to the Buyer a copy of any written notice of any suspected infringement of any Patent Rights in the Territory delivered or received by the Seller, as well as copies of material correspondence related thereto, as soon as practicable and in any event not more than [***] following such delivery or receipt.

(d) Within [***] of initiating, or permitting a Licensee to initiate, an enforcement action regarding any suspected infringement by a Third Party of any Patent Right in the Territory, the Seller shall provide the Buyer with written notice of such enforcement action.

(e) If the Seller recovers monetary damages from a Third Party in an action brought for such Third Party’s infringement of any Patent Rights in the Territory relating to a Product, where such damages, whether in the form of judgment or settlement, are awarded for such infringement of such Patent Rights, (i) such recovery will be allocated first to the reimbursement of any expenses incurred by the Seller (or any party to an In-License or Permitted Out-License of such Patent Rights entitled to such reimbursement under any such In-License or Permitted Out-License ) in bringing such action (including all reasonable attorney’s fees), (ii) any remaining amounts will be reduced, if applicable, to comply with allocation of recovered damages with licensors of such Patent Rights required under any In-Licenses or Licensees of such Patent Rights under any Permitted Out-Licenses, if any, and (iii) any residual amount of such damages after application of (i) and (ii) will be treated as Net Sales to the extent set forth therein with respect to the applicable Product for the purposes of this Agreement.

Section 6.6 In-Licenses.

(a) The Seller shall promptly (and in any event within [***]) provide the Buyer with (i) executed copies of any In-License entered into by the Seller or its Affiliates, and (ii) executed copies of each amendment, supplement, modification or written waiver of any provision of any In-License.

(b) The Seller shall use Commercially Reasonable Efforts to comply in all material respects with its obligations under any In-Licenses it enters into and shall not take any action or forego any action that would reasonably be expected to result in a material breach thereof. Promptly, and in any event within [***], after receipt of any (written or oral) notice from a counterparty to any In-License or its Affiliates of an alleged material breach under any In-License, the Seller shall provide the Buyer a copy thereof (or if restricted by applicable confidentiality obligations under such In-License, notification thereof and a reasonably detailed summary of such material breach). The Seller shall use its Commercially Reasonable Efforts to cure any such material breaches by it under any In-License and shall give written notice to the Buyer upon curing any such breach. The Seller shall provide the Buyer with written notice following becoming aware of a counterparty’s material breach of its obligations under any In-License. The Seller shall not terminate any In-License without providing the Buyer prior written notice. Promptly, and in any event within [***] following the Seller’s notice to a counterparty to any In-License of an alleged breach by such counterparty under any such In-License, the Seller shall provide the Buyer a copy thereof.

(d) The Seller shall provide the Buyer prompt (and in any event within [***]) written notice of a material breach by a Licensee or of any of its obligations under any Permitted Out-License, of which any of the individuals named in the definition of “Knowledge of the Seller” (or the successors of such Person at the Seller) becomes aware.

(b) The Buyer and the Seller shall cooperate and provide assistance as reasonably requested by the other party, at the expense of such other party (other than expenses that are Losses subject to indemnification in accordance with Article 7), in connection with any Third Party litigation, arbitration or other Third Party proceeding with respect to the Revenue Participation Right, or the Product Collateral (whether threatened, existing, initiated, or contemplated prior to, on or after the date hereof) to which any party hereto or any of its officers, directors, shareholders, agents or employees is or may become a party or is or may become otherwise directly or indirectly affected or as to which any such Persons have a direct or indirect interests, in each case relating to this Agreement, any other Transaction Document, the Revenue Participation Right or any other Product Collateral, or the transactions described herein or therein.

Section 6.12 Non-Impairment; Back-Up Security Interest(a) . The Seller shall not, and shall not permit any Subsidiary to, as may be applicable, (a) enter into any contracts or arrangement or otherwise knowingly take any action or knowingly fail to act in a manner that would, individually or in the aggregate, reasonably be expected to materially and adversely affect the Buyer’s rights to the Revenue Participation Right or the Back-Up Security Interest, or (b) take any action or engage in any transaction (or series of actions or transactions), whether by reorganization, transfer of assets, merger, dissolution, amendment of organizational documents or otherwise, the primary purpose of which is to evade, avoid or seek to avoid the performance or observance of the covenants, agreements or obligations of the Seller under the Transaction Documents; provided, however, that such clauses (a) and (b) shall not restrict the incurrence of Indebtedness or Liens or the entry into Out-Licenses, in each case to the extent not otherwise prohibited under this Agreement or otherwise be deemed to expand or modify any affirmative or negative covenants in this ‎ARTICLE 6. At the Closing Date, the Seller shall grant in favor of Buyer, and take such additional actions as reasonably requested by Xxxxx to ensure that thereafter, prior to the occurrence of a Release Event, Buyer has a valid, continuing, first priority security interest in and to all right, title and interest in, to and under the Revenue Participation Right and the Royalty Payments and a security interest in and to all right, title and interest in, to and under the Product Collateral in accordance with the terms set forth in ‎Section 2.1.

Section 6.13 Certain Tax Matters.

(a) The Seller and the Buyer agree that for U.S. federal Tax purposes, the Seller and the Buyer shall treat the transactions contemplated by this Agreement as a sale of the Revenue Participation Right. The Seller shall not, by reason of its duties and functions hereunder, be deemed to be acting as a partner of or to be engaged in a joint venture, association or syndication with, the Buyer for tax purposes. The parties hereto agree not to take any position that is inconsistent with the provisions of this ‎Section 6.13(a) on any U.S. tax return or in any audit or other tax-related administrative or judicial proceeding in the U.S. unless the other party hereto has consented in writing (such consent not to be unreasonably withheld, conditioned or delayed) to such actions. If there is an inquiry by any Governmental Entity of the Buyer or the Seller related to the treatment described in this ‎Section 6.13(a), the parties hereto shall cooperate with each other in responding to such inquiry in a reasonable manner which is consistent with this ‎Section 6.13(a).

(b) The parties hereto acknowledge and agree that, as of the date hereof, all payments by the Seller (or, following any assignment in accordance with Section 10.3 to Milestone US) to the Buyer and by the Buyer to the Seller shall be made without deduction or withholding for any Taxes. If any change in applicable law requires the deduction or withholding of any Tax from any payment by the Seller, then the Seller shall be entitled to withhold and deduct (or cause to be withheld and deducted) from any amount payable under this Agreement to the Buyer any Tax that it is required to withhold and deduct under applicable law. The Seller shall timely pay the full amount deducted or withheld to the relevant governmental authority in accordance with applicable law. For the avoidance of doubt and notwithstanding anything to the contrary in this Agreement, any amount payable by the Seller to the Buyer shall be increased as necessary so that after deduction or withholding of any Tax has been made (including such deductions and withholdings applicable to additional sums payable under this ‎Section 6.13(b)) (whether as a result of a change in applicable law or otherwise), the Buyer receives an amount equal to the sum it would have received had no such deduction or withholding been made; provided, however, that if, as a result of a Withholding Action by the Buyer, the amount of any tax withheld or deducted exceeds the amount of such withholding or deduction that would have been required in the absence of such Withholding Action, the Seller shall be required to pay an additional amount only to the extent that the Seller would be required to pay any additional amount to the Buyer pursuant to this ‎Section 6.13(b) if the Buyer had not committed such Withholding Action (except to the extent such excess additional amounts results from a change in applicable law that occurs after the date of such Withholding Action).

Section 6.14 Use of Proceeds. The Seller shall use proceeds received from Buyer pursuant to this Agreement in support of Commercialization of the Products.

ARTICLE 7

INDEMNIFICATION

Section 7.1 General Indemnity. From and after the Closing:

(a) the Seller hereby agrees to indemnify, defend and hold harmless the Buyer and its Affiliates and its and their directors, managers, trustees, officers, agents and employees (the “Buyer Indemnified Parties”) from, against and in respect of all Losses suffered or incurred by the Buyer Indemnified Parties to the extent arising out of or resulting from (i) any breach of any of the representations or warranties of the Seller in this Agreement, (ii) any breach of any of the covenants or agreements of the Seller in this Agreement and (iii) any Indemnified Taxes; and

(b) the Buyer hereby agrees to indemnify, defend and hold harmless the Seller and its Affiliates and its and their directors, officers, agents and employees (the “Seller Indemnified Parties”) from, against and in respect of all Losses suffered or incurred by the Seller Indemnified Parties to the extent arising out of or resulting from (i) any breach of any of the representations or warranties of the Buyer in this Agreement and (ii) any breach of any of the covenants or agreements of the Buyer in this Agreement.

Section 7.2 Notice of Claims. If either a Buyer Indemnified Party, on the one hand, or a Seller Indemnified Party, on the other hand (such Buyer Indemnified Party on the one hand and such Seller Indemnified Party on the other hand being hereinafter referred to as an “Indemnified Party”), has suffered or incurred any Losses for which indemnification may be sought under this ‎ARTICLE 7, the Indemnified Party shall so notify the other party from whom indemnification is sought under this ‎ARTICLE 7 (the “Indemnifying Party”) promptly in writing describing such Loss, the amount or estimated amount thereof, if known or reasonably capable of estimation, and the method of computation of such Loss, all with reasonable particularity and containing a reference to the provisions of this Agreement in respect of which such Loss shall have occurred. If any claim, action, suit or proceeding is asserted or instituted by or against a Third Party with respect to which an Indemnified Party intends to claim any Loss under this ‎ARTICLE 7, such Indemnified Party shall promptly notify the Indemnifying Party of such claim, action, suit or proceeding and tender to the Indemnifying Party the defense of such claim, action, suit or proceeding. A failure by an Indemnified Party to give notice and to tender the defense of such claim, action, suit or proceeding in a timely manner pursuant to this ‎Section 7.2 shall not limit the obligation of the Indemnifying Party under this ‎ARTICLE 7, except to the extent such Indemnifying Party is actually prejudiced thereby.

Section 7.3 Claim Procedures. In case any such action is brought against an Indemnified Party and it notifies the Indemnifying Party of the commencement thereof, the Indemnifying Party will be entitled to participate therein and, to the extent that it may wish, jointly with any other Indemnifying Party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such Indemnified Party, and after notice from the Indemnifying Party to such Indemnified Party of its election so to assume the defense thereof, the Indemnifying Party will not be liable to such Indemnified Party under this ‎Section 7.3 for any legal or other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof other than reasonable costs of investigation. In any such proceeding, an Indemnified Party shall have the right to retain its own counsel reasonably satisfactory to the Indemnifying Party, but the reasonable fees and expenses of such counsel shall be at the expense of such Indemnified Party unless (a) the Indemnifying Party has assumed the defense of such proceeding and has failed within a reasonable time to retain counsel reasonably satisfactory to such Indemnified Party or (b) the named parties to any such proceeding (including any impleaded parties) include both the Indemnifying Party and the Indemnified Party and representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of interests between them based on the advice of such counsel. It is agreed that the Indemnifying Party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate law firm (in addition to local counsel where necessary) for all such Indemnified Parties. The Indemnifying Party shall not be liable for any settlement of any proceeding effected without its written consent. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, which shall not be unreasonably withheld, conditioned, or delayed, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such proceeding.

Section 7.4 Limitations on Liability.

(a) Except for claims arising from a breach of confidentiality obligations under ‎ARTICLE 8 or in cases of fraud, gross negligence, or willful misconduct, no party hereto shall be liable for any consequential, punitive, special or incidental damages under this ‎ARTICLE 7 (and no claim for indemnification hereunder shall be asserted) as a result of any breach or violation of any covenant or agreement of such party (including under this ‎ARTICLE 7) in or pursuant to this Agreement. In connection with the foregoing, the parties hereto acknowledge and agree that (a) the Buyer’s damages, if any, for any such action or claim will include Losses for Royalty Payments that the Buyer was entitled to receive in respect of its ownership of the Royalty Payments but did not receive timely or at all due to such indemnifiable event and (b) the Buyer shall be entitled to make claims for all such missing or delayed Royalty Payments as Losses hereunder, and such missing or Royalty Payments shall not be deemed consequential, punitive, special, indirect or incidental damages.

Section 7.5 Exclusive Remedy. Except as set forth in ‎Section 10.10, from and after Closing, the rights of the parties hereto pursuant to (and subject to the conditions of) this ‎ARTICLE 7 shall be the sole and exclusive remedy of the parties hereto and their respective Affiliates with respect to any Losses (whether based in contract, tort or otherwise) resulting from or relating to any breach of the representations, warranties covenants and agreements made under this Agreement or any certificate, document or instrument delivered hereunder, and each party hereto hereby waives, to the fullest extent permitted under applicable law, and agrees not to assert after Closing, any other claim or action in respect of any such breach. Notwithstanding the foregoing, claims for fraud, gross negligence, or willful misconduct shall not be waived or limited in any way by this ‎ARTICLE 7.

Section 7.6 Tax Treatment of Indemnification Payments. For all purposes hereunder, any indemnification payments made pursuant to this ‎ARTICLE 7 will be treated as an adjustment to the Purchase Price for Tax purposes, including U.S. federal income tax to the fullest extent permitted by applicable law.

Section 7.7 Survival. All representations and warranties made herein and in any other Transaction Document, any certificates or in any other writing delivered pursuant hereto or thereto shall survive the execution and delivery of this Agreement and shall continue to survive until the expiration or termination of this Agreement in accordance with ‎ARTICLE 9.

ARTICLE 8

In any event, the Buyer shall not file any patent application based upon or using the Confidential Information of the Seller provided hereunder.

(c) Notwithstanding any provision in in this Agreement to the contrary, materials and documentation relating to the Seller’s Intellectual Property Rights may be only disclosed to or accessed by the Buyer and its attorneys and auditors, without further disclosure to any other Representative of the Buyer.
