Binding Letter of Intent for License of Intellectual Property

Napo has entered into a binding letter of intent for the license of a use patent and regulatory and other information regarding NP-500, a clinical stage product which Napo has identified and which in pre-clinical animal studies has been shown to benefit symptoms of diabetes and cardiovascular risk factors known as metabolic disease, and to mitigate risk of stroke. NP-500 is a known compound with a novel mechanism of action relative to agents currently approved and in clinical testing. The compound has progressed through multi- dose Phase 1 testing.

The license will allow Napo to have access to the regulatory package filed with the United States Federal Drug Administration, and to access technology protected by a use patent in the United States. The license to the regulatory package provides the data to allow NP-500 to progress into Phase 2 proof of concept testing. Napo hopes to work with a partner to generate related proprietary compounds.

The consideration for the license consists of initial payments of $1,500,000 ($500,000 of which is payable on signature of the Letter of Intent), plus milestone payments and royalties.

Use of Placing Proceeds

Proceeds from the financing will be used to progress NP-500 toward Phase 2 studies for the indications of insulin-resistant diseases of Type II diabetes and metabolic syndrome.

Napo also intends to expand the Company’s operations including the testing, subject to FDA approval, of a lower dose of crofelemer in the final Phase 3 clinical trial of crofelemer for HIV/AIDS related diarrhea (CRO-HIV) prior to commercialization. Based on recent data, the Company feels lower dose investigation could potentially benefit the commercial development of all crofelemer clinical indications. Finally, Napo will also evaluate the opportunity for EU approval for CRO-HIV.CRO-HIV has fast-track designation from the FDA.

Commenting on this announcement, Lisa A. Conte, Napo’s Chief Executive Officer, said: “This financing demonstrates continued investor interest in the Napo business plan. Based on recent data and to optimize the commercial value of crofelemer upon launch, it is important that the Company have the financial resources to potentially test lower doses of crofelemer in our upcoming Phase 3 trial for HIV/AIDS related diarrhea. Pricing and reimbursement will be based on tested doses. We are also pleased with the diversification to an additional clinical stage product the NP-500 program allows. Diabetes and insulin-resistance syndromes are epidemic throughout the world, afflicting up to 30 per cent of the population. Napo is looking forward to progressing NP- 500 through the clinic to commercialization in conjunction with global partnerships.”

Dr. Gerald Reaven, Professor Emeritus at Stanford and a leading expert on insulin-resistant diseases, and Medical Advisor to Napo’s Board of Directors, commented: “The therapeutic benefits of NP-500 observed in relevant pre- clinical models of type 2 diabetes, dyslipidemia, and essential hypertension raises the possibility that this compound may address the clustering of metabolic abnormalities present in these diverse clinical syndromes that distinguishes it from any of the pharmacological approaches that are now available. This benefit gives this compound an advantage, compared to the currently approved products, which affect only one of these disease targets.”
