Seller has the corporate power and authority to own, operate and lease its properties and to carry on its business as presently conducted and is duly qualified or licensed to do business and is in good standing in each jurisdiction where the character of its properties owned or leased or the nature of its activities make such qualification or licensing necessary, except where the failure to be so qualified or licensed would not, individually or in the aggregate, reasonably be expected to adversely affect any of the Purchased Assets or Buyer’s ownership and rights with respect to, or use of, any of the Purchased Assets after the Closing. Seller is not in violation of its certificate of incorporation or bylaws, in each case as amended to date.

3.2 Due Authority. Seller has all requisite corporate power and authority to execute and deliver, perform its obligations under, and consummate the transactions contemplated by, this Agreement.

This Agreement, upon execution by the Parties, will constitute a valid and binding obligation of Seller enforceable against Seller in accordance with its terms, subject only to the effect, if any, of (a) applicable bankruptcy and other similar laws affecting the rights of creditors generally and (b) rules of law governing specific performance, injunctive relief and other equitable remedies.

3.3 No Contravention. The execution and delivery by Seller of this Agreement does not, and the consummation of the transactions contemplated hereby, including the transfer of title to, ownership in, and possession of the Purchased Assets, will not, (a) result in the creation of any Encumbrance on any of the Purchased Assets or (b) conflict with, or result in any violation of or default under (with or without notice or lapse of time, or both), or give rise to a right of termination, cancellation or acceleration of any obligation or loss of any benefit under, or require any consent, approval or waiver from any Person pursuant to, (i) any provision of the certificate of incorporation or bylaws or other organizational or governing documents of Seller, in each case as amended to date, (ii) any Contract to which Seller is a party or bound by or by which its assets or properties are bound or under which Seller has material rights or benefits or (iii) any Legal Requirements applicable to Seller or any of its assets or properties.

3.4 No Consents. Except for (a) any Antitrust Approvals required by the HSR Act or any other applicable Legal Requirements relating to competition, merger control or antitrust, and (b) the letters referenced in Section 2.4(b), no Consent of a Governmental Entity or any other Person, on the part of Seller is necessary or required in connection with the execution, delivery and performance by Seller of this Agreement, and the consummation by Seller of the transactions contemplated hereby.

3.5 Title to Purchased Assets. Seller is the sole and exclusive owner of the Purchased Assets and owns good and transferable title to the Purchased Assets free and clear of any Encumbrances. Seller has performed all actions necessary to perfect its ownership of, and its ability to transfer, the Purchased Assets.

3.6 Contracts. Except for this Agreement, there is no Contract to which Seller or any of its Affiliates is a party to or bound by that involves or affects (or may involve or affect) the issuance of, ownership of, transfer of, title to, or use of any of the Purchased Assets, or that otherwise assigned, transferred, licensed, conveyed or encumbered, or granted or allowed to exist any Encumbrance with respect to, any of its right, title or interest in, to or under the Purchased Assets.

3.7 Compliance With Legal Requirements. Seller and its Affiliates are, and at all times have been, in compliance with all Legal Requirements that are or were applicable to the Purchased Assets or such Person’s conduct, acts, or omissions with respect to the Purchased Assets. None of Seller or any of its Affiliates has received any written or, to Seller’s Knowledge, oral notice or other communication from any Person regarding any actual, alleged, possible or potential violation of, or failure to comply with, any such Legal Requirement.

3.8 Legal Proceedings. There is no pending, or to Seller’s Knowledge, threatened, Action involving Seller or any of its Affiliates, nor has there been an Action involving Seller or any of its Affiliates, and neither Seller nor any of its Affiliates are a party or subject to the provisions of any Judgment, (a) that involves or affects (or may involve or affect) the issuance of, ownership of, transfer of, title to, or use of any of the Purchased Assets, or (b) challenging the transactions contemplated by this Agreement. To the Knowledge of Seller, there is no fact or circumstance that would reasonably be expected to serve as a basis for any of the foregoing Actions.

3.9 Governmental Authorizations. Neither Seller nor any of its Affiliates is required to hold any license, registration, or permit issued by any Governmental Entity to own, use or transfer the Purchased Assets, other than such licenses, registrations or permits that have already been obtained.

The remaining assets of Seller after the Closing will not be unreasonably small in relation to the business in which Seller will engage after the Closing. Upon and immediately following the Closing Date, after giving effect to all of the transactions contemplated by and in this Agreement (including the payment of the Purchase Price), Seller will not be insolvent and will have sufficient capital to continue in business and pay its debts as they become due.

3.11 Revocation; Use of Purchased Assets. The Priority Review Voucher has not been terminated, canceled or revoked and to Seller’s Knowledge there are no facts or circumstances that could reasonably be expected to (with or without notice or lapse of time, or both) give rise to a right of FDA to terminate, cancel or revoke the Priority Review Voucher or that could reasonably be expected to preclude (a) the sale of the Purchased Assets to Buyer, or (b) Buyer’s use of the Purchased Assets to obtain Priority Review or any other benefit associated with the Purchased Assets. Neither Seller nor any of its Affiliates has notified FDA of its own intent to use the Priority Review Voucher.

3.12 Marketed Product. Seller has initiated marketing in the United States of the rare pediatric disease product for which the Priority Review Voucher was awarded within the three hundred sixty five (365)-day period beginning on the date of the FDA approval of such rare pediatric disease product and has continuously marketed such product in the United States since Seller initiated marketing of such product.

3.13 Brokers. Except for Xxxxxxxxx LLC, the fees and expenses of which shall be paid by Seller, no broker, finder or investment banker is entitled to any brokerage or finder’s fee in connection with the purchase and sale of the Purchased Assets hereunder or any of the other transactions contemplated by this Agreement based upon arrangements made by or on behalf of Seller.

3.14 No Other Representations.

Each Party shall, and shall cause its Affiliates and its and their respective officers, directors, employees and agents to, keep confidential and not publish or otherwise disclose to a third party and not use, directly or indirectly, for any purpose, any Confidential Information furnished or otherwise made known to it, directly or indirectly, by the other Party, except to the extent such disclosure or use is expressly permitted by the terms of this Agreement. In addition, with respect to Confidential Information received from a Party, the other Party will (i) not use such Confidential Information for any reason other than to carry out the intent and purpose of this Agreement, and (ii) not disclose such Confidential Information to any Person, except in each case as otherwise expressly permitted by this Agreement or with the prior written consent of the disclosing Party. Notwithstanding the foregoing, to the extent the receiving Party can demonstrate by documentation or other competent proof, the confidentiality and non-use obligations under this Section 5.8 with respect to any Confidential Information shall not include any information that:

Further, any combination of Confidential Information shall not be considered in the public domain or in the possession of the receiving Party merely because individual elements of such Confidential Information are in the public domain or in the possession of the receiving Party unless the combination and its principles are in the public domain or in the possession of the receiving Party.

5.9 Permitted Disclosures. Each Party may disclose Confidential Information to the extent that such disclosure is:

(a) in the reasonable opinion of the receiving Party’s legal counsel, required to be disclosed pursuant to Law, regulation or a valid order of a court of competent jurisdiction or other Governmental Entity of competent jurisdiction (including by reason of filing with securities regulators, but subject to Section 5.10); provided, that the receiving Party shall first have given prompt written notice (and to the extent possible, at least five (5) Business Days’ notice) to the disclosing Party and given the disclosing Party a reasonable opportunity to take whatever action it deems necessary to protect its Confidential Information (for example, quash such order or to obtain a protective order or confidential treatment requiring that the Confidential Information and documents that are the subject of such order be held in confidence by such court or Governmental Entity or, if disclosed, be used only for the purposes for which the order was issued). In the event that no protective order or other remedy is obtained, or the disclosing Party waives compliance with the terms of this Agreement, the receiving Party shall furnish only that portion of Confidential Information which the receiving Party is advised by counsel is legally required to be disclosed;

(b) made to its or its Affiliates’ financial and legal advisors who have a need to know such disclosing Party’s Confidential Information and are either under professional codes of conduct giving rise to expectations of confidentiality and non-use or under written agreements of confidentiality and non-use, in each case, at least as restrictive as those set forth in this Agreement; provided, that the receiving Party shall remain responsible for any failure by such financial and legal advisors, to treat such Confidential Information as required under this Article;

(c) made by or on behalf of Buyer or its Affiliates to the FDA or other Governmental Entity as required in connection with any filing, application or request for regulatory approval in which Priority Review is sought; or

(d) made by Buyer or its Affiliates to its or their advisors, consultants, clinicians, vendors, service providers, contractors, existing or prospective collaboration partners, licensees, sublicensees, or other third parties as may be necessary or useful in connection with the transactions contemplated by this Agreement, including the use of the Purchased Assets to obtain Priority Review; provided, that such Persons shall be subject to obligations of confidentiality and non-use with respect to such Confidential Information substantially similar to (and at least as restrictive as those set forth in this Agreement) the obligations of confidentiality and non-use of the receiving Party pursuant to Section 5.8.

5.10 Public Announcements. Seller and Buyer shall consult with each other before issuing, and provide each other the opportunity to review and comment upon, any press release or other public statement with respect to the transactions contemplated hereby, and shall not issue any such press release or make any such public statement prior to such consultation, except as may be required by applicable Law. Buyer and Seller each acknowledges that the other Party, as a publicly traded company is legally obligated to make timely disclosures of materials events relating to its business. The Parties acknowledge that either or both Parties may be obligated to file a copy of this Agreement with the United States Securities and Exchange Commission. Without limiting the foregoing, any Party so obligated shall provide the other Party with a reasonable opportunity to review, comment and request confidential treatment of this Agreement pursuant to applicable rules under the Securities Exchange Act of 1934, as amended, and the Freedom of Information Act and the rules promulgated thereunder to permit the filing of a redacted exhibit. Notwithstanding the foregoing, without prior submission to or approval of the other Party, either Party may issue press releases or public announcements which incorporate information concerning this Agreement which information was included in a press release or public disclosure which was previously disclosed under the terms of this Agreement.

5.11 Use of Name. Except as expressly provided herein, neither Party shall mention or otherwise use the name, logo, or trademark of the other Party or any of its Affiliates (or any abbreviation or adaptation thereof) in any publication, press release, marketing and promotional material, or other form of publicity without the prior written approval of such other Party in each instance. The restrictions imposed by this Section 5.11 shall not prohibit either Party from making any disclosure identifying the other Party that, in the opinion of the disclosing Party’s counsel, is required by applicable Law or the rules of a stock exchange on which the securities of the disclosing Party are listed; provided, that such Party shall submit the proposed disclosure identifying the other Party in writing to the other Party as far in advance as reasonably practicable (and in no event less than two (2) Business Days prior to the anticipated date of disclosure) so as to provide a reasonable opportunity to comment thereon.

Within one (1) Business Day following the Effective Date, Buyer and Seller will jointly submit the notification of Buyer’s intent to redeem the Priority Review Voucher, in substantially the form attached hereto as Exhibit 5.12 (the “Pending Transfer Notification”).

(a) A claim for indemnification for any matter not involving a Third Party Claim may be asserted by written notice to the Party from whom indemnification is sought. Such notice shall include the facts constituting the basis for such claim for indemnification, the Sections of this Agreement upon which such claim for indemnification is then based and an estimate, if possible, of the amount of Losses suffered or reasonably expected to be suffered by the Indemnified Party.

(b) In the event that any claim shall be instituted or asserted by any third party in respect of which payment may be sought under Section 8.1(a) or Section 8.1(b) hereof (each, a “Third Party Claim”), the Indemnified Party shall promptly cause written notice of the assertion of any Third Party Claim of which it has knowledge which is covered by the provisions of Section 8.1(a) or Section 8.1(b), as applicable, to be forwarded to the Indemnifying Party. The failure of the Indemnified Party to give reasonably prompt notice of any Third Party Claim shall not release, waive or otherwise affect the Indemnifying Party’s obligations with respect thereto except to the extent that the Indemnifying Party is actually prejudiced as a result of such failure. The Indemnifying Party shall have the right, at its sole option and expense, to be represented by counsel reasonably acceptable to the Indemnified Party and to defend against, negotiate, settle or otherwise deal with any Third Party Claim which relates to any Losses indemnified by it hereunder, subject to the provisions below; provided, however, that the Indemnifying Party may not assume control of defense to a Third Party Claim (i) in which equitable relief other than monetary damages is sought, or (ii) if the Indemnifying Party has not notified the Indemnified Party in writing that it will be liable to indemnify the Indemnified Party with respect to all Losses relating to such Third Party Claim.

If the Indemnifying Party shall assume the defense of any Third Party Claim pursuant to the terms of this Agreement, the Indemnified Party may participate, at his or its own expense, in the defense of such Third Party Claim; provided, however, that such Indemnified Party shall be entitled to participate in any such defense with separate counsel at the expense of the Indemnifying Party if (A) so requested by the Indemnifying Party to participate or (B) in the reasonable opinion of outside counsel to the Indemnified Party a conflict or potential conflict exists between the Indemnified Party and the Indemnifying Party that would make such separate representation advisable. The Parties hereto agree to reasonably cooperate with each other in connection with the defense, negotiation or settlement of any such Third Party Claim. Notwithstanding anything in this Section 8.2 to the contrary, the Indemnifying Party shall not, without the written consent of the Indemnified Party, settle or compromise any Third Party Claim or permit a default or consent to entry of any judgment unless (1) the claimant provides to the Indemnified Party an unqualified release of the Indemnified Parties from all liability in respect of such Third Party Claim, (2) such settlement does not involve any injunctive relief binding upon the Indemnified Party or any of its Affiliates, (3) such settlement does not encumber any of the material assets of any Indemnified Party or impose any restriction or condition that would apply to or materially affect any Indemnified Party or the conduct of any Indemnified Party’s business, and (4) such settlement does not involve any admission of liability or wrongdoing by any Indemnified Party or any of its Affiliates.

(c) In the event that the Indemnified Party conducts the defense of the Third Party Claim pursuant to this Section 8.2, the Indemnifying Party will (i) advance the Indemnified Party promptly and periodically for the reasonable costs of defending against the Third Party Claim (including reasonable attorneys’ and experts’ fees and expenses) and (ii) remain responsible for any and all other Losses that the Indemnified Party may incur or suffer resulting from, arising out of, relating to, in the nature of or caused by the Third Party Claim to the fullest extent provided in this ARTICLE 8.

8.3 Direct Claims. A claim for indemnification for any matter not involving a Third Party Claim may be asserted by written notice to the Party from whom indemnification is sought. Such notice shall include the facts constituting the basis for such claim for indemnification, the Sections of this Agreement upon which such claim for indemnification is then based, and an estimate, if possible, of the amount of Damages suffered or reasonably expected to be suffered by the Indemnitee.

8.4 Adjustments. Any amount paid under this Article VIII shall be treated as an adjustment to the Purchase Price for all tax purposes unless otherwise required by applicable Legal Requirements.

8.5 Survival. All covenants, representations and warranties of the Parties under this Agreement shall survive the execution and delivery of this Agreement and the Closing, as applicable, and (except with respect to claims based on breach of covenant or breach of any of the representations and warranties set forth in Section 3.1, 3.2, 3.3, 3.4, 3.5, 3,10, 3.11, 3.12, 3.13, 4.1, 4.2, 4.3, 4.4 or 4.5, all of which shall survive until the expiration of the applicable statutes of limitations) claims based upon a breach of such representations and warranties will expire at 11:59 p.m. eastern time on the date that is two (2) years after the Closing Date.

Re: Transfer of Rare Pediatric Disease Priority Review Voucher No. PRV BLA 761171

Y-mAbs is the original recipient of the Voucher and has not previously transferred the Voucher.

Pursuant to the Agreement, Y-mAbs has sold, transferred, assigned, conveyed and delivered the Voucher to UT, and UT has acquired and accepted the Voucher from Y-mAbs, effective _________, 2021. This transfer is free and clear of all liens and provides UT will all of Y-mAbs’ rights, titles and interest in, to, and under, the Voucher.

This letter acknowledges that Y-mAbs has transferred, assigned, conveyed, and delivered the Voucher to UT. This letter will be presented to FDA as evidence that Y-mAbs acknowledges the sale and transfer of the Voucher from Y-mAbs to UT.

	Sincerely,

NDA 214324

Tyvaso^™ DPI (treprostinil) Inhalation Powder

Sequence No: 0001

Joint Notification of United Therapeutics Corp Intent to Submit a New Drug Application (NDA 214324) with a Rare Pediatric Disease Priority Review Voucher

Dear Xx. Xxxxxxxxxxx:

Pursuant to Section 529(b)(4)(B)(i) of the Federal Food, Drug, and Cosmetic Act, United Therapeutics Corporation (“UTC”) and Y-mAbs Therapeutics, Inc. (“Y-mAbs”) hereby submit notice of UTC’s intent to submit a 505(b)(1) New Drug Application (the NDA”) for a dry powder inhalation formulation of treprostinil (Tyvaso DPI™) no earlier than April 1, 2021, with the Rare Pediatric Disease Priority Review Voucher PRV BLA 761171 (the “Voucher”). The sponsor of the NDA will be UTC.

The Voucher was issued to Y-mAbs upon approval of BLA 761171 for DANYELZA^® (naxitamab-gqgk) injection, as evidenced in the Federal Register (85 Fed. Reg. 78859 (Dec. 7, 2020)). The Voucher has not been transferred since it was issued.

Y-mAbs and UTC have entered into an Asset Purchase Agreement (the “Agreement”), dated December 24, 2020, pursuant to which Y-mAbs will transfer the Voucher to UTC upon closing, following expiration or early termination of the waiting period under the Xxxx-Xxxxx-Xxxxxx Antitrust Improvement Act of 1976, as amended (“HSR”), and the satisfaction of certain other customary closing conditions. We anticipate closing will occur on or about January 29, 2021, but the precise closing date depends primarily on how quickly the HSR closing condition is satisfied.

Promptly following closing of the Agreement, both UTC and Y-mAbs will submit letters to FDA acknowledging the transfer of the Voucher from Y-mAbs to UTC. UTC discussed this process via e-mail with FDA’s PDUFA User Fee Staff (Xxxxx Xxxx, RPh, ExecJD) on December 9 and 10, 2020 and was given authorization to proceed with this notice.

Please do not hesitate to contact either of the undersigned with any questions, at the email addresses and telephone numbers noted below.

Sincerely,
