Item 1.01. Entry into a Material Definitive Agreement.

On May 2, 2021, Sonnet BioTherapeutics, Inc. (the “Company”) entered into a License Agreement (the “Agreement”) with New Life Therapeutics PTE, LTD., a company organized under the laws of Singapore (“New Life”). Pursuant to the Agreement, Sonnet granted New Life an exclusive license (with the right to sublicense) to develop and commercialize pharmaceutical preparations containing a specific recombinant human interleukin-6 (or any derivatives, fragments or conjugates thereof) (the “Compound”) (such preparations, the “Products”) for the prevention, treatment or palliation of diabetic peripheral neuropathy in humans (the “DPN Field”) in Malaysia, Singapore, Indonesia, Thailand, Philippines, Vietnam, and Brunei (the “Exclusive Territory”). New Life may exercise the option to expand (1) the field of the exclusive license to include the prevention, treatment or palliation of chemotherapy-induced peripheral neuropathy in humans (the “CIPN Field”), which option is non-exclusive and will expire on December 31, 2021; and/or (2) the territorial scope of the license to include the People’s Republic of China, Hong Kong and/or India, which option is exclusive and will also expire on December 31, 2021. Sonnet is excluded from developing, using, selling or otherwise commercializing any Compounds or Products for use in the DPN Field in the Exclusive Territory during the term of the Agreement.

The Company retains all rights to manufacture Compounds and Products anywhere in the world. The Company and New Life shall enter into a follow-on supply agreement pursuant to which the Company shall supply to New Life Productsfor development and commercialization thereof in the DPN Field (and the CIPN Field, if applicable) in the Exclusive Territory on terms to be negotiated by the parties..

Pursuant to the terms of the Agreement, New Life will bear the cost of, and be responsible for, among other things, conducting clinical studies and additional non-clinical studies (if any, subject to both parties’ approval), preparing and filing applications for regulatory approval and undertaking other developmental and regulatory activities for and commercializing Products in the DPN Field (and the CIPN Field, if applicable) in the Exclusive Territory. New Life will own and maintain all regulatory filings and approvals for Products in the Exclusive Territory.

In consideration of the license and other rights granted by the Company, New Life will pay the Company, within 30 days of the date of the Agreement, a $500,000 upfront cash payment and is obligated to pay a deferred license fee of an additional $1,000,000 at the time of the satisfaction of certain milestones as well as potential additional milestone payments to the Company totaling up to $19,000,000 subject to the achievement of certain development and commercialization milestones. In addition, during the Royalty Term (as defined below), New Life is obligated to pay the Company tiered double digit royalties ranging from 12% to 30% based on annual net sales of Products in the Territory. The “Royalty Term” means, on a Product-by-Product and a country-by-country basis in the Exclusive Territory, the period commencing on the date of the first commercial sale (subject to certain conditions) of such Product in such country in the Exclusive Territory and continuing until New Life ceases commercialization of such Product in the DIPN Field (or CIPN Field, if applicable). In the event New Life (i) files for an initial public offering or (ii) is subject to a Change of Control, the royalty obligations may be converted to equity subject to mutual agreement of the parties.

In addition, New Life shall pay to the Company a percentage, in the double digits, of all revenue received through sub-licensing of each Product, subject to certain exclusions.

Sonnet retains the sole responsibility to pay its third party licensors to the extent such obligations are applicable to the rights granted to New Life with respect to the Products and shall remain liable for all obligations under the license related to the Compounds and Products between Sonnet and ARES Trading SA.

The Agreement will remain in effect on a Product-by-Product, country-by-country basis and will expire upon the expiration of the Royalty Term for the last-to-expire Product in the last-to-expire country, subject to (i) each party’s early termination rights including for material breach or insolvency or bankruptcy of the other party and (ii) the Company’s Buy Back Right and New Life’s Give Back Right (as defined below).

In addition, New Life granted to the Company an exclusive option to buy back the rights granted by the Company to New Life and the Company granted New Life the right to give back the rights with respect to Products in the DPN Field and/or the CIPN Field (if applicable) in one or more countries in the Exclusive Territory on terms to be agreed upon, which options will expire upon the initiation of a Phase III Trial for the applicable Product.

Pursuant to the Agreement, the parties agreed to develop a joint development committee to provide strategic oversight of the parties’ collaboration activities under the Agreement, including to coordinate the development of Licensed Products in the Territory.

The Agreement also contains customary representations, warranties and covenants by both parties, as well as customary provisions relating to indemnification, confidentiality and other matters.

The foregoing description of the terms of the Agreement is qualified in its entirety by reference to the full text of the Agreement, which will be filed as an exhibit to the Company’s Quarterly Report on Form 10-Q for the quarterly period ending March 31, 2021.
