Alvogen Licensing Agreement
Alvogen Licensing Agreement	6. Alvogen Licensing Agreement On June 2, 2023, the Company entered into the License Agreement with Alvogen. The Company and Alvogen are referred to below individually as a “Party” and collectively as the “Parties.” License Grant Under the License Agreement, the Company granted Alvogen an exclusive (even as to the Company and its affiliates) worldwide, transferable and sublicensable license under certain intellectual property (including patents, know-how and trademarks) owned or controlled by the Company to develop (with certain limitations), manufacture, and commercialize the Company’s candidate therapeutic product, NRX-101, for the treatment of bipolar depression with suicidality. The term of the license is, on a country-by-country basis, 20 years from the first commercial sale of NRX-101 in such country, extendable by Alvogen for a two-year period upon its request made prior to the expiration of such 20-year period. During the term of the License Agreement, the Parties agree (on behalf of themselves and their affiliates) not to research, develop, seek or obtain any regulatory approval for the manufacturing, marketing, sale, or other commercialization of any product containing a fixed dose combination of D-cycloserine and lurasidone in the treatment of bipolar depression with suicidality, nor to authorize or assist (including by investing in or otherwise providing funding to) any third party to do so. During the term, the Company is permitted to develop additional products containing D-cycloserine in combination with one or more other active antidepressant or antipsychotic ingredients for use outside of the field of treatment of bipolar depression with suicidality, such as in post-traumatic stress disorder (PTSD) or chronic pain in depression, in which case, if the Company wishes to license rights to develop or commercialize such additional products or indications, Alvogen has a right of first negotiation to obtain such a license. Term and Termination The License Agreement will remain in force until the earlier to occur of (i) 20 years following the first commercial sale of NRX-101 on a country-by-country basis (which may be extended for a two-year period at Alvogen’s request), and (ii) the date that the agreement is terminated under its early termination provisions. Early termination grounds include, subject to applicable cure periods, a material breach of agreement by the other Party, the bankruptcy or insolvency of the other Party, or a party’s reasonable belief that there is an unacceptable risk for harm in humans based upon preclinical safety data or the observation of serious adverse effects in humans. In addition, Alvogen has the right to early termination if (i) the phase 2 study relating to NRX-101 is not completed and/or a successful read out from the study does not occur by March 31, 2024, or (ii) there is no completion of a Type B meeting with the FDA by March 31, 2024. Alvogen may also terminate upon sixty (60) days’ prior written notice to the Company at any time after the First Milestone Payment (as defined below) has been made. The Company also has the right to terminate the License Agreement if the current phase 2 study successfully concludes prior to March 31, 2024 and the Type B meeting with the FDA is completed by March 31, 2024 and Alvogen does not notify the Company within 60 days that it wishes to proceed with the development of NRX-101 or has not paid the First Milestone Payment. Upon expiration or termination of the License Agreement, the intellectual property rights licensed to Alvogen under the License Agreement will revert to the Company, and all other rights and obligations of each of the parties will immediately cease, except for outstanding amounts owed as of the time of such expiration or termination. Upon termination, Alvogen will grant to the Company an exclusive irrevocable, perpetual, worldwide, royalty-bearing, sublicensable, transferrable license under the NDA rights to develop, manufacture, have manufactured, or commercialize the product in the field of bipolar depression with suicidality. Such reversion license would be granted by Alvogen to the Company in exchange for an equitable royalty payable by the Company to Alvogen that would be negotiated and agreed in good faith by the parties within 30 business days of such matter being presented to them. Milestone Payments In exchange for the license grant and the participation of the Company in the development, regulatory and commercial activities described below, Alvogen was obligated to pay the Company an initial $9 million cash payment upon the later of a positive data read-out from the Company’s ongoing Phase 2b/3 clinical trial and completion of the Type B meeting with the U.S. FDA (the “First Milestone Payment”). In February 2024, the parties executed an amendment accelerating payment of $5 million related to the First Milestone Payment, with the remaining $4 million due upon the original agreement’s terms. Refer to Note 14 for more information regarding the amendment. A second milestone payment of $5 million (the “Approval Payment”) is due upon Alvogen’s receipt of a copy of the FDA’s notice of NDA Approval for Product with the label indication for the treatment of bipolar depression with sub-acute or acute suicidality. Additional bonus milestone payments of increasing amounts up to $315 million will be payable upon the achievement of net sales targets measured over the trailing four quarters. Alvogen also will pay royalties (as described below) to the Company based on the net sales of NRX-101, with a reduction in royalties on a country-by-country basis upon expiration or termination of the Company’s patent protection on the NRX-101 composition. Royalties Subject to certain adjustments for sublicensing and other deductions, commencing on the first commercial sale of NRX-101, Alvogen has agreed to pay to the Company tiered royalties calculated on the basis of a percentage, ranging from the low to mid-teens, of annual net sales of NRX-101 measured over the trailing four quarters. In addition, if Alvogen sublicenses NRX-101 in any country other than the U.S. (in which the royalty rates described above will apply), Alvogen will pay the Company a percentage of any and all consideration received by Alvogen or its affiliates from sublicensing any of the rights granted. Development and Regulatory Activities Prior to payment of the First Milestone Payment by Alvogen to the Company, each Party has agreed to perform, at its own cost, certain development activities using diligent efforts and in accordance with applicable then-current good manufacturing and other applicable practices, laws and regulations, with the goal of supporting the preparation and filing of an NDA and obtaining regulatory approval for NRX-101. Until the payment of the First Milestone Payment, the Company has the sole right to control and responsibility for all regulatory matters relating to NRX-101, at its sole cost and expense, and the Company shall own all regulatory materials and own all worldwide regulatory approvals for NRX-101. After the payment of the First Milestone Payment, Alvogen has the sole right and responsibility, at its cost and expense, for all regulatory matters relating to NRX-101, and Alvogen will own all regulatory materials and all regulatory approvals for the product in the licensed territory (and the Company will assign all of its rights in any regulatory materials to Alvogen). Each party has committed to reasonably cooperate with the other in carrying out the development and regulatory activities outlined in the development plan. In addition, Alvogen has agreed to fund the next registrational study of NRX-101 in the field of treatment of bipolar depression with suicidality. Upon NDA approval of the product in the U.S., Alvogen has agreed to use diligent efforts to commercialize NRX-101 in the U.S., and, for 24 months following such approval, in other countries in the territory upon regulatory approval in each such country. If Alvogen does not commercialize NRX-101 in a country outside of the U.S. in the foregoing 24-month period, then the license may revert back to the Company with respect to such country and the Company would pay Alvogen tiered royalties in the low to mid-teens based on net sales of NRX-101 in such country. The Parties will also enter into a pharmacovigilance agreement to ensure compliance with safety reporting requirements of all applicable regulatory agencies globally with respect to the commercialization of NRX-101. Commercial Activities Under the License Agreement, the Company is responsible for and will control the manufacturing of the NRX-101 commercial product and for qualification and regulatory-related activities necessary for the manufacture of the product. The Parties intend to enter into a clinical supply agreement (and a related quality agreement) on reasonable and customary terms, in which the Company will supply Alvogen raw materials and/or finished product without any markup to the future supply price from the Company’s current contract manufacturer. Similarly, prior to initiation of the first Phase 3 study for the commercial product, the Parties will enter into a commercial supply agreement (and a related quality agreement) on reasonable and customary terms, in which the Company will supply Alvogen raw materials and/or finished product without any markup to the future supply price from NRx’s current contract manufacturer. At any time after NDA approval, Alvogen may elect to manufacture, fill and package the product itself or through a third-party supplier subject to the prior approval of the Company. In such case, the parties may also work together to establish a written manufacturing technology transfer plan to transfer manufacturing technology from the Company or the Company’s contract manufacturer to Alvogen or Alvogen’s designated third party supplier. The Company has agreed, as a part of its manufacturing commitments, to make available its qualified technical personnel to consult with Alvogen to complete transfer of the manufacturing technology if required under the License Agreement. Following NDA approval, Alvogen will control and be responsible for advertising, marketing, promotion and marketing, pricing, and terms of sale for the product, all at Alvogen’s sole expense. Alvogen has committed to not shift, allocate, price or discount sales of the product for the purpose of reducing or disadvantaging the net sales of the product in order to reduce the payments owed by Alvogen to the Company under the License Agreement. As of December 31, 2023, the Company has not achieved any milestones nor recognized any revenue associated with the License Agreement (see Note 14).

Upon expiration or termination of the License Agreement, the intellectual property rights licensed to Alvogen under the License Agreement will revert to the Company, and all other rights and obligations of each of the parties will immediately cease, except for outstanding amounts owed as of the time of such expiration or termination. Upon termination, Alvogen will grant to the Company an exclusive irrevocable, perpetual, worldwide, royalty-bearing, sublicensable, transferrable license under the NDA rights to develop, manufacture, have manufactured, or commercialize the product in the field of bipolar depression with suicidality. Such reversion license would be granted by Alvogen to the Company in exchange for an equitable royalty payable by the Company to Alvogen that would be negotiated and agreed in good faith by the parties within 30 business days of such matter being presented to them.

Milestone Payments

In exchange for the license grant and the participation of the Company in the development, regulatory and commercial activities described below, Alvogen was obligated to pay the Company an initial $9 million cash payment upon the later of a positive data read-out from the Company’s ongoing Phase 2b/3 clinical trial and completion of the Type B meeting with the U.S. FDA (the “First Milestone Payment”). In February 2024, the parties executed an amendment accelerating payment of $5 million related to the First Milestone Payment, with the remaining $4 million due upon the original agreement’s terms. Refer to Note 14 for more information regarding the amendment. A second milestone payment of $5 million (the “Approval Payment”) is due upon Alvogen’s receipt of a copy of the FDA’s notice of NDA Approval for Product with the label indication for the treatment of bipolar depression with sub-acute or acute suicidality. Additional bonus milestone payments of increasing amounts up to $315 million will be payable upon the achievement of net sales targets measured over the trailing four quarters. Alvogen also will pay royalties (as described below) to the Company based on the net sales of NRX-101, with a reduction in royalties on a country-by-country basis upon expiration or termination of the Company’s patent protection on the NRX-101 composition.

Royalties

Subject to certain adjustments for sublicensing and other deductions, commencing on the first commercial sale of NRX-101, Alvogen has agreed to pay to the Company tiered royalties calculated on the basis of a percentage, ranging from the low to mid-teens, of annual net sales of NRX-101 measured over the trailing four quarters. In addition, if Alvogen sublicenses NRX-101 in any country other than the U.S. (in which the royalty rates described above will apply), Alvogen will pay the Company a percentage of any and all consideration received by Alvogen or its affiliates from sublicensing any of the rights granted.

Development and Regulatory Activities

Prior to payment of the First Milestone Payment by Alvogen to the Company, each Party has agreed to perform, at its own cost, certain development activities using diligent efforts and in accordance with applicable then-current good manufacturing and other applicable practices, laws and regulations, with the goal of supporting the preparation and filing of an NDA and obtaining regulatory approval for NRX-101. Until the payment of the First Milestone Payment, the Company has the sole right to control and responsibility for all regulatory matters relating to NRX-101, at its sole cost and expense, and the Company shall own all regulatory materials and own all worldwide regulatory approvals for NRX-101.

After the payment of the First Milestone Payment, Alvogen has the sole right and responsibility, at its cost and expense, for all regulatory matters relating to NRX-101, and Alvogen will own all regulatory materials and all regulatory approvals for the product in the licensed territory (and the Company will assign all of its rights in any regulatory materials to Alvogen). Each party has committed to reasonably cooperate with the other in carrying out the development and regulatory

activities outlined in the development plan. In addition, Alvogen has agreed to fund the next registrational study of NRX-101 in the field of treatment of bipolar depression with suicidality.

Upon NDA approval of the product in the U.S., Alvogen has agreed to use diligent efforts to commercialize NRX-101 in the U.S., and, for 24 months following such approval, in other countries in the territory upon regulatory approval in each such country. If Alvogen does not commercialize NRX-101 in a country outside of the U.S. in the foregoing 24-month period, then the license may revert back to the Company with respect to such country and the Company would pay Alvogen tiered royalties in the low to mid-teens based on net sales of NRX-101 in such country. The Parties will also enter into a pharmacovigilance agreement to ensure compliance with safety reporting requirements of all applicable regulatory agencies globally with respect to the commercialization of NRX-101.

Commercial Activities

Under the License Agreement, the Company is responsible for and will control the manufacturing of the NRX-101 commercial product and for qualification and regulatory-related activities necessary for the manufacture of the product. The Parties intend to enter into a clinical supply agreement (and a related quality agreement) on reasonable and customary terms, in which the Company will supply Alvogen raw materials and/or finished product without any markup to the future supply price from the Company’s current contract manufacturer. Similarly, prior to initiation of the first Phase 3 study for the commercial product, the Parties will enter into a commercial supply agreement (and a related quality agreement) on reasonable and customary terms, in which the Company will supply Alvogen raw materials and/or finished product without any markup to the future supply price from NRx’s current contract manufacturer. At any time after NDA approval, Alvogen may elect to manufacture, fill and package the product itself or through a third-party supplier subject to the prior approval of the Company. In such case, the parties may also work together to establish a written manufacturing technology transfer plan to transfer manufacturing technology from the Company or the Company’s contract manufacturer to Alvogen or Alvogen’s designated third party supplier. The Company has agreed, as a part of its manufacturing commitments, to make available its qualified technical personnel to consult with Alvogen to complete transfer of the manufacturing technology if required under the License Agreement.

Following NDA approval, Alvogen will control and be responsible for advertising, marketing, promotion and marketing, pricing, and terms of sale for the product, all at Alvogen’s sole expense. Alvogen has committed to not shift, allocate, price or discount sales of the product for the purpose of reducing or disadvantaging the net sales of the product in order to reduce the payments owed by Alvogen to the Company under the License Agreement.
