(d) Notwithstanding that the Seller and the Purchaser expressly intend for the sale, assignment, transfer, conveyance and granting of the Purchased Royalties to be a true, complete, absolute and irrevocable sale and assignment, and for the purposes of providing additional assurance to the Purchaser, the Seller hereby assigns, conveys, grants and pledges to the Purchaser, from and after the Closing, subject to the terms and conditions of this Purchase and Sale Agreement, as security for its obligations created hereunder in the event that the transfer contemplated by this Purchase and Sale Agreement is held not to be a sale, a first priority security interest in and to all of the Seller’s right, title and interest in, to and under the Purchased Royalties and, in such event, this Purchase and Sale Agreement shall constitute a security agreement

Section 2.2 Purchase Price. In full consideration for the sale, assignment, transfer, conveyance and granting of the Purchased Royalties, and subject to the terms and conditions set forth herein, the Purchaser shall pay (or cause to be paid) to the Seller, the sum of $31,000,000 in cash (the “Purchase Price”), without any deduction or withholding on account of any Taxes, within 15 Business Days after Purchaser receives notice from Seller in accordance with ‎Section 5.1(f) of this Agreement of grant of centralized Marketing Authorization in the European Union by the European Commission of the Product

Section 2.3 No Assumed Obligations. Notwithstanding any provision in this Purchase and Sale Agreement or any other writing to the contrary, the Purchaser is purchasing, acquiring and accepting only the Purchased Royalties and is not assuming any liability or obligation of the Seller or any of the Seller’s Affiliates of whatever nature, whether presently in existence or arising or asserted hereafter, including any liability or obligation of the Seller under the Commercialization Agreement or any Related Agreement. All such liabilities and obligations shall be retained by, and remain liabilities and obligations of, the Seller or the Seller’s Affiliates, as the case may be (the “Excluded Liabilities and Obligations”).

Section 2.4 Excluded Assets. The Purchaser does not, by purchase, acquisition or acceptance of the right, title or interest granted hereunder or otherwise pursuant to any of the Transaction Documents, purchase, acquire or accept any assets or contract rights of the Seller under the Commercialization Agreement, other than the Purchased Royalties, or any other assets of the Seller.

Section 2.5 Buyout Option. The Seller may, at its option, make a payment at any time, upon providing [[***]] Business Days prior written notice to the Purchaser, equal to the difference between (a) the applicable Royalty Cap at such time and (b) the aggregate amount of payments paid to the Purchaser under this Purchase and Sale Agreement at such time. If the Seller makes such payment to the Purchaser then the Royalty Termination Date shall be deemed to have occurred, and this Purchase and Sale Agreement shall terminate pursuant to ‎Section 9.1.

Section 2.6 Special Payment. If [[***]] has not been achieved on or prior to [[***]], then within [[***]] (i.e. no later than [[***]]) (or within [[***]] of the date (if earlier than [[***]]) any Party receives notice that [[***]] will not be achieved prior to [[***]]) Seller shall make a one-time cash payment to Purchaser in the amount of $9,000,000 (the “Special Payment”). If the Special Payment is made, in consideration for the Special Payment the Purchaser shall transfer all of its right, title and interest in the [[***]] to Seller, and shall take such actions as Seller reasonably requests (at Purchaser’s sole expense) to evidence such transfer, including entering into a bill of sale.

The Seller shall, upon the reasonable request of the Purchaser and at the Purchaser’s expense, reasonably cooperate with the Purchaser and use its commercially reasonable efforts to make such filings and take such other actions as may be reasonably necessary and specified by the Purchaser in order to allow an exemption from or reduction of any Permitted Tax Withholding; provided that Seller shall have no obligation under this sentence in respect of any withholding Tax resulting from Purchaser’s failure to provide any Purchaser Tax Forms at least ten Business Days prior to the due date of the applicable payment of the Purchased Royalties by the Licensee.

(b) As promptly as practicable after the Closing Date (and from time to time thereafter upon the reasonable request of the Seller or the Licensee), the Purchaser shall deliver properly executed and duly completed versions of the applicable French tax forms number 5000 and 5003, as such forms may be amended from time to time, or such other appropriate documentation evidencing the Purchaser’s exemption from French withholding tax on royalty payments (as mutually agreed by the Parties) (collectively, the “Purchaser Tax Forms”). Any amounts payable to Purchaser under this Agreement shall be net of any applicable withholding Taxes, including, for the avoidance of doubt, any applicable withholding Taxes due to a failure of the Purchaser to timely provide any Purchaser Tax Forms (and any amounts so withheld shall be treated as having been paid to Purchaser). If, as a result of any failure by Purchaser to provide any Purchaser Tax Forms within the time frame set forth in Section 5.10(a), except for any such failure resulting from a change in law after the date on which the Purchaser provides its initial Purchaser Tax Forms, (i) the amount of funds that would have been distributed to Seller from the Escrow Account had Purchaser timely provided the Purchaser Tax Forms is greater than (ii) the amount of funds in the Escrow Account to be distributed to Seller (such excess, the “Shortfall”), Purchaser shall indemnify and hold harmless Seller for the Shortfall and any other Losses incurred by Seller as a result of Purchaser’s failure to timely provide the Purchaser Tax Forms.

Section 5.11 Escrow Agreement. The Parties agree to negotiate and enter into an Escrow Agreement within 60 days of the Closing Date.

Section 7.3 Procedures for Third-Party Claims.

(a) If any Third-Party Claim shall be brought or alleged against an indemnified party in respect of which indemnity is to be sought against an indemnifying party pursuant to ‎Section 7.1 or ‎Section 7.2, the indemnified party shall, promptly after receipt of notice of the commencement of such Third-Party Claim, notify the indemnifying party in writing of the commencement thereof, enclosing a copy of all papers served, if any; provided that the omission to so notify such indemnifying party will not relieve the indemnifying party from any liability that it may have to any indemnified party under ‎Section 7.1 or ‎Section 7.2 unless, and only to the extent that, the indemnifying party is actually prejudiced by such omission.

(b) In the event that any Third-Party Claim is brought against an indemnified party and it notifies the indemnifying party of the commencement thereof in accordance with this ‎Section 7.3, the indemnifying party will be entitled, at the indemnifying party’s sole cost and expense, to participate therein and, to the extent that it may wish, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnifying party, be counsel to the indemnified party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, subject to clause (c), the indemnifying party will not be liable to such indemnified party under this ‎ARTICLE VII for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof.

(c) In any such Third-Party Claim, an indemnified party shall have the right to retain its own counsel, but the reasonable fees and expenses of such counsel shall be at the sole cost and expense of such indemnified party unless (a) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (b) 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 (c) the named parties to any such Third-Party Claim (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 counsel to the indemnified party. It is agreed that the indemnifying party shall not, in connection with any Third-Party Claim or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate law firm (in addition to local counsel where necessary) for all such indemnified parties.

(d) The indemnifying party shall not be liable for any settlement of any Third-Party Claim effected without its written consent, but, if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any Loss by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or discharge of any pending or threatened Third-Party Claim in respect of which any indemnified party is or could have been a party and indemnity could be sought hereunder by such indemnified party, unless such settlement, compromise or discharge, as the case may be, (i) includes an unconditional, full written release of such indemnified party, in form and substance reasonably satisfactory to the indemnified party, from all liability on claims that are the subject matter of such claim or proceeding, (ii) does not include any statement as to an admission of fault, culpability or failure to act by or on behalf of any indemnified party and (iii) does not impose any continuing obligations or restrictions other than customary and reasonable confidentiality obligations relating to such claim, settlement or compromise.

Section 7.4 Other Claims. A claim by an indemnified party under this ‎ARTICLE VII for any matter not involving a Third-Party Claim and in respect of which such indemnified party would be entitled to indemnification hereunder may be made by delivering, in good faith, a written notice of

33


 

demand to the indemnifying party, which notice shall contain (a) a description and the amount of any Losses incurred or suffered or reasonably expected to be incurred or suffered by the indemnified party, (b) a statement that the indemnified party is entitled to indemnification under this ‎ARTICLE VII for such Losses and a reasonable explanation of the basis therefor, and (c) a demand for payment in the amount of such Losses; provided, that the failure to so notify such indemnifying party will not relieve the indemnifying party from any liability that it may have to any indemnified party under ‎Section 7.1 or ‎Section 7.2 unless, and only to the extent that, the indemnifying party is actually prejudiced by such failure. For all purposes of this ‎Section 7.4, the Seller shall be entitled to deliver such notice of demand to the Purchaser on behalf of the Seller Indemnified Parties, and the Purchaser shall be entitled to deliver such notice of demand to the Seller on behalf of the Purchaser Indemnified Parties.

Section 7.5 Time Limitations.

(a) The Seller shall have liability under ‎Section 7.1 with respect to any breach of any representation or warranty made by the Seller in any of the Transaction Documents or certificates delivered by the Seller to the Purchaser in writing pursuant to this Purchase and Sale Agreement only if, on or prior to the date that is [[***]] after the Closing date (other than (i) ‎Section 3.1 (Organization), ‎Section 3.2 (Authorization), ‎Section 3.7 (No Brokers’ Fees), ‎Section 3.11 (UCC Matters) (such representations and warranties, the “Fundamental Representations”), as to which a claim may be made on or prior to the date that is six months after the termination of this Purchase and Sale agreement, and (ii) ‎Section 3.3 (No Conflicts), ‎Section 3.4 (Ownership), ‎‎‎Section 3.5 (Governmental and Third Party Authorizations), ‎Section 3.9(a) (Intellectual Property Matters), ‎Section 3.9(d) (Intellectual Property Matters), ‎Section 3.10(a) (Counterparty Agreements), ‎Section 3.10(b) (Counterparty Agreements), ‎Section 3.10(c) (Counterparty Agreements) (solely with respect to the first sentence thereof), ‎Section 3.10(e) (Counterparty Agreements) (solely with respect to the second, third, and sixth sentences thereof), and ‎Section 3.16 (Tax Matters), as to which a claim may be made on or prior to the date that is [[***]] after the Closing Date), the Purchaser notifies the Seller of a claim, specifying the factual basis of such claim in reasonable detail.

(b) The Purchaser shall have liability under ‎Section 7.2 with respect to any breach of any representation or warranty made by the Purchaser in any of the Transaction Documents or any certificate delivered by the Purchaser to the Seller in writing pursuant to this Purchase and Sale Agreement only if, on or prior to the date that is [[***]] after the Closing Date (other than ‎Section 4.1 (Organization), ‎Section 4.2 (Authorization), ‎Section 4.3 (No Conflicts), as to which a claim may be made on or prior to the date that is [[***]] after the termination of this Purchase and Sale Agreement), the Seller notifies the Purchaser of a claim, specifying the factual basis of such claim in reasonable detail.

Section 7.6 Exclusive Remedy. Except in the case of fraud or intentional misrepresentation, and except as set forth in ‎Section 10.1, the indemnification afforded by this ‎ARTICLE VII shall be the sole and exclusive remedy for any and all Losses awarded against or incurred or suffered by a Party in connection with the transactions contemplated by the Transaction Documents, including with respect to any breach of any representation or warranty made by a Party in any of the Transaction Documents or any certificate delivered by a Party to the other Party in writing pursuant to this Purchase and Sale Agreement or any breach of or default under any covenant or agreement by a Party pursuant to any Transaction Document.

Section 7.7 Limitations. Notwithstanding anything in this Purchase and Sale Agreement to the contrary, (a) in no event shall any Party have any liability for special, punitive, exemplary, indirect, incidental, or consequential (including lost profits) damages, whether in contract or tort, regardless of whether the other Party shall be advised, shall have reason to know, or in fact shall know of the possibility of such damages suffered or incurred by any such Seller Indemnified Party or Purchaser

34


 

Indemnified Party in connection with this Purchase and Sale Agreement, any of the other Transaction Documents, or any of the transactions contemplated hereby or thereby, except to the extent any such damages are actually paid to a Third Party in accordance with Section 8.3 and (b) the Seller shall not have any liability (i) under ‎Section 7.1(a) (other than with respect to the Fundamental Representations) in excess of an amount [[***]], (ii) under ‎Section 7.1 in excess of an amount equal to [[***]], and (iii) under ‎Section 7.1 unless and until the aggregate amount of all Losses incurred by the Purchaser Indemnified Party equals or exceeds [[***]], in which event the Seller shall be liable for Losses including such amount. Notwithstanding the foregoing, the limitations set forth in this ‎Section 7.7 shall not apply to any claim for indemnification hereunder in the case of fraud, intentional misrepresentation, or willful misconduct. The Parties acknowledge and agree that (a) the Purchaser’s Losses, if any, for any indemnifiable events under this Purchase and Sale Agreement will typically include Losses for Purchased Royalties that the Purchaser was entitled to receive in respect of its ownership of the Purchased Royalties but did not receive timely or at all due to such indemnifiable event and (b) subject to this ‎Section 7.7, the Purchaser shall be entitled to make indemnification claims for all such missing or delayed Purchased Royalties that the Purchaser was entitled to receive in respect of its ownership of the Purchased Royalties as Losses hereunder (which claims shall be reviewed and assessed by the Parties in accordance with the procedures set forth in this ‎ARTICLE VII), and such missing or delayed Purchased Royalties shall not be deemed special, punitive, exemplary, indirect, incidental, consequential, or lost profits for any purpose of this Purchase and Sale Agreement. For the avoidance of doubt, the Seller shall have no liability to the Purchaser or any Purchaser Indemnified Party for any Permitted Reduction or Credit Event.

ARTICLE VIII

Section 8.1 Confidentiality. Except as provided in this ‎ARTICLE VIII or otherwise agreed in writing by the Parties, the Parties agree that, during the term of this Purchase and Sale Agreement and until the [[***]] anniversary of the date of termination of this Purchase and Sale Agreement, each Party (the “Receiving Party”) shall keep confidential, and shall not publish or otherwise disclose and shall not use for any purpose other than as provided for in this Purchase and Sale Agreement (which includes the exercise of any rights or the performance of any obligations hereunder), any information (whether written or oral, or in electronic or other form) furnished to it by or on behalf of the other Party (the “Disclosing Party”) pursuant to the Existing Confidentiality Agreement or this Purchase and Sale Agreement, including the terms of this Purchase and Sale Agreement (such information, “Confidential Information” of the Disclosing Party), except for that portion of such information that:

(a) was already in the Receiving Party’s possession on a non-confidential basis prior to its disclosure to it by the Disclosing Party, or becomes known to the Receiving Party from a source other than the Disclosing Party and its representatives without any breach of this Purchase and Sale Agreement, in each case as evidenced by written records (provided, if such information was disclosed to the Receiving Party on a non-confidential basis by a source that is not the Disclosing Party, such source to the knowledge of the Receiving Party had the right to disclose such information to the Receiving Party without any legal, contractual or fiduciary obligation to any person with respect to such information);

(b) is or becomes generally available to the public other than as a result of an act or omission by the Receiving Party or its Affiliates in breach of this Purchase and Sale Agreement; or

Section 8.2 Termination of Confidentiality Agreement. Effective upon the date hereof, the Existing Confidentiality Agreement shall terminate and be of no further force or effect, and shall be superseded by the provisions of this ‎ARTICLE VIII.

Section 8.3 Required Disclosure. In the event that the Receiving Party or its Affiliates or any of its or its Affiliates’ representatives are requested by a Governmental or Regulatory Authority or required by Applicable Law, regulation or legal process (including the regulations of a stock exchange or governmental or regulatory authority or the order or ruling of a court, administrative agency or other government or regulatory body of competent jurisdiction) to disclose any Confidential Information, the Receiving Party shall promptly, to the extent permitted by Applicable Law, notify the Disclosing Party in writing of such request or requirement so that the Disclosing Party may seek an appropriate protective order or other appropriate remedy (and if the Disclosing Party seeks such an order or other remedy, the Receiving Party will provide such cooperation, at the Receiving Party’s sole expense, as the Disclosing Party shall reasonably request). If no such protective order or other remedy is obtained and the Receiving Party or its Affiliates or its or its Affiliates’ representatives are, in the view of their respective counsel (which may include their respective internal counsel), legally required to disclose Confidential Information, the Receiving Party or its Affiliates or its or its Affiliates’ representatives, as the case may be, shall only disclose that portion of the Confidential Information that their respective counsel advises that the Receiving Party or its Affiliates or its or its Affiliates’ representatives, as the case may be, are required to disclose and will exercise commercially reasonable efforts, at the Disclosing Party’s sole expense, to obtain reliable assurance that confidential treatment will be accorded to that portion of the Confidential Information that is being disclosed. In any event, the Receiving Party will not oppose action by the Disclosing Party to obtain an appropriate protective order or other reliable assurance that confidential treatment will be accorded the Confidential Information. Notwithstanding the foregoing, notice to the Disclosing Party shall not be required where disclosure is made (i) in response to a request by a Governmental or Regulatory Authority having competent jurisdiction over the Receiving Party, its Affiliates or its or its Affiliates’ representatives, as the case may be, or (ii) in connection with a routine examination by a regulatory examiner, where in each case such request or examination does not expressly reference the Disclosing Party, its Affiliates, the Purchased Royalties or this Purchase and Sale Agreement.

Section 8.4 Permitted Disclosure. The Receiving Party may disclose Confidential Information to the extent such disclosure is reasonably necessary to its Affiliates, its and their employees, directors, officers, contractors, agents, and representatives, and to potential or actual acquirers, merger partners, permitted assignees, (sub)licensees, licensors, investment bankers, investors, limited partners, partners, lenders, or other financing sources (including, in the case of the Seller, any party evaluating the acquisition of any portion of the Royalties that are not included in the Purchased Royalties), and their respective directors, employees, contractors and agents, provided that each such person or entity agrees to confidentiality and non-use obligations with respect thereto at least as stringent as those specified for in this ‎ARTICLE VIII. Further, notwithstanding anything contained in this Agreement, including ‎ARTICLE VIII, to the contrary, the Seller may disclose Confidential Information to the extent such disclosure is reasonably necessary to comply with the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, or with any rule, regulation or legal process promulgated by the SEC or a stock exchange, subject to the Seller’s obligations set forth in ‎Section 5.2.

Section 8.5 Other Relevant Obligations. In addition to, and without limiting, the Purchaser’s obligations under this ‎ARTICLE VIII, the Purchaser shall fully comply with any confidentiality obligations of the Seller or any of its Affiliates under the Commercialization Agreement that are applicable to the Confidential Information.

(c) Each Party shall give written notice to the other Parties of any assignment permitted by this ‎Section 10.4 promptly (but in any event, within five Business Days) after the occurrence thereof. The Seller shall be under no obligation to reaffirm any representations, warranties or covenants made in this Purchase and Sale Agreement or any of the other Transaction Documents or take any other action in connection with any such assignment by any Purchaser or by the Purchaser. Any purported assignment of rights or delegation of obligations in violation of this ‎Section 10.4 will be void.
