Jaguar Health Enters Non-Binding Agreement of Terms to Issue a Secured Convertible Note to Iliad Research and Trading, L.P. (an Affiliate of Chicago Venture Partners, L.P.), as Jaguar Expands Commercial Efforts for Mytesi

November 8, 2017

SAN FRANCISCO--(BUSINESS WIRE)--Nov. 8, 2017-- Jaguar Health, Inc. (NASDAQ: JAGX) ("Jaguar"), a natural-products pharmaceuticals company focused on developing and commercializing novel, sustainably derived gastrointestinal products for both human prescription use and animals on a global basis, announced today that it has signed a non-binding term sheet to issue to Iliad Research and Trading, L.P. (the "Investor") a secured convertible promissory note (the "Note") in the aggregate principal amount of $1,375,000 for an aggregate purchase price of $1,100,000. The Note will bear interest at the rate of 8.0% per annum, with a fixed conversion price of $0.52/share, and will be due nine months after its issue date.

Funding of the Note is subject to, among other things, the approval by Jaguar shareholders of the aggregate number of shares issuable upon conversion of the Note and a secured convertible promissory note (the "Existing Note") issued by Jaguar to Chicago Venture Partners, L.P. ("CVP"), an affiliate of the Investor, in June 2017.

Jaguar plans to use the proceeds from the transaction primarily for inventory build-up of Mytesi®, an FDA-approved, first-in-class anti-secretory human prescription drug product of Jaguar's wholly-owned subsidiary, Napo Pharmaceuticals, Inc. (Napo), and for general corporate purposes.

"Jaguar's relationship with CVP dates back to June of this year, when, prior to the merger of Jaguar Animal Health and Napo, Jaguar entered into a separate securities purchase agreement with CVP," Lisa Conte, Jaguar's president and CEO, stated. "We are pleased to continue working with CVP as we have now entered and are expanding commercial efforts for Mytesi®. Build-up of Mytesi® inventory will help maximize support for 'all four legs of the stool'—our growing direct salesforce, the multiple initiatives we have underway nationally to expand awareness about Mytesi® among consumers, our medical education initiatives, and the expansion of our clinician-focused marketing and promotional activities beyond HIV physicians to the large number of gastroenterologists who see significant numbers of HIV patients—and all of these efforts are further supported by the broad reimbursement coverage available for Mytesi®."

Launched by Napo in October 2016, Mytesi® is the only antidiarrheal studied in and U.S. FDA-approved for the symptomatic relief of noninfectious diarrhea in adults living with HIV/AIDS on antiretroviral therapy (ART). Mytesi® is a prescription treatment for diarrhea that works differently, by acting locally in the GI tract to normalize the flow of water. Mytesi® does not have drug-drug interactions with ART, does not affect GI motility, and has side effects that are similar to placebo.

Jaguar estimates the potential U.S. market for Mytesi® to be approximately $100 million in gross annual sales, and anticipates that Mytesi® will generate approximately $7.0 million in revenue by April 2018 for its current, FDA-approved specialty indication.

Under the terms of the term sheet, the Note, similar to the Existing Note, will be secured by substantially all the veterinary assets of Jaguar upon the earlier to occur of (i) the repayment in full of Jaguar's existing indebtedness to Hercules Capital, Inc. ("Hercules"), related to the loan and security agreement, dated August 18, 2015, between Jaguar and Hercules, or (ii) the purchase by the Investor of Jaguar's existing indebtedness to Hercules, in either case, upon the same terms set forth in the security agreement dated as of June 29, 2017 between Jaguar and CVP.

About Mytesi®

Mytesi® (crofelemer) is an antidiarrheal indicated for the symptomatic relief of noninfectious diarrhea in adult patients with HIV/AIDS on antiretroviral therapy (ART). Mytesi® is not indicated for the treatment of infectious diarrhea. Rule out infectious etiologies of diarrhea before starting Mytesi®. If infectious etiologies are not considered, there is a risk that patients with infectious etiologies will not receive the appropriate therapy and their disease may worsen. In clinical studies, the most common adverse reactions occurring at a rate greater than placebo were upper respiratory tract infection (5.7%), bronchitis (3.9%), cough (3.5%), flatulence (3.1%), and increased bilirubin (3.1%).

More information and complete Prescribing Information are available at Mytesi.com. Crofelemer, the active ingredient in Mytesi®, is a botanical (plant-based) drug extracted and purified from the red bark sap of the medicinal Croton lechleri tree in the Amazon rainforest. Napo has established a sustainable harvesting program for crofelemer to ensure a high degree of quality and ecological integrity.
