SAN FRANCISCO, CA / ACCESSWIRE / October 4, 2019 / Jaguar Health, Inc. (NASDAQ:JAGX) ("Jaguar" or the "Company"), today announced that a License Termination and Settlement agreement ("LTSA") related to SP-303, a component of Mytesi^® (crofelemer), has been entered between Michael Tempesta, Ph.D. ("Tempesta"), Jaguar, and Jaguar's wholly-owned subsidiary, Napo Pharmaceuticals, Inc. ("Napo"), as well as their predecessors (collectively, "Jaguar"), regarding the license agreement Napo and Tempesta entered in 2002 (the "2002 License"). SP-303 is extracted and purified from the bark latex of the medicinal Croton lechleri tree in the Amazon rainforest.

"We're very pleased to have entered into the LTSA," Lisa Conte, Jaguar's president and CEO commented. "Jaguar entered into the LTSA with Dr. Tempesta to end the uncertainty as to the enforceability of the 2002 License and avoid potentially costly litigation. This reduction of COGS also enhances the value of our business development and potential licensing collaborations. As a result of the settlement, Dr. Tempesta will participate in future sales of Mytesi through the stock ownership that he received as a part of the consideration in the LTSA."

Tempesta originally entered into a license agreement in 1990 (the "1990 License") with Shaman Pharmaceuticals ("Shaman") related to SP-303, and Napo is a successor-in-interest to Shaman. In 2002, Napo and Tempesta entered into a modified license agreement, the 2002 License, thereby terminating the 1990 License. Per the terms of the LTSA, the 2002 License, subject to specified provisions regarding an event of default, shall be deemed terminated as of September 30, 2018.

Per the terms of the LTSA, Jaguar paid $50,000 to Tempesta and issued him an unsecured promissory note for the amount of $550,000 (the "Note"). The Note bears simple interest at 2 1/2% per year and specifies semi-annual payments of $50,000 plus accrued interest, beginning on March 1, 2020 and continuing until the Note is paid in full. Jaguar will also deliver to Tempesta 40,000 shares of Jaguar common stock (the "Shares"). The Shares shall be "locked-up" and not tradeable by Tempesta prior to October 1, 2020.
