Item 1.01 Entry into a Material Definitive Agreement.

On July 13, 2016, Radius Health, Inc. (the “Company,” “we,” and “our”) entered into a Manufacturing Services Agreement (the “Manufacturing Agreement”) with Lonza Sales Ltd (“Lonza”), effective as of June 28, 2016. Pursuant to the Manufacturing Agreement, Lonza has agreed to manufacture the commercial supply of the active pharmaceutical ingredient for abaloparatide (the “API”), the Company’s lead drug product candidate. The Company and Lonza previously entered into a Development and Manufacturing Services Agreement, dated October 16, 2007, as amended, under which Lonza provided the API for clinical development.

Under the Manufacturing Agreement, Lonza has agreed to manufacture the API pursuant to purchase orders and in accordance with the forecasts provided by the Company and the manufacturing specifications agreed upon between the Company and Lonza. The Company has agreed to purchase the API in batches at a price per gram in euros, subject to an annual increase by Lonza. The Company is also required to purchase a minimum number of batches annually. The Company may be obligated to pay certain fees upon cancellation of purchase orders, for additional storage of the API, or for failure to timely deliver to Lonza any materials that may be supplied by the Company.

The Manufacturing Agreement has an initial term of six years, beginning on June 28, 2016, and will automatically renew for successive three-year terms unless either party provides notice of non-renewal 24 months before the end of the then-current term. Lonza may terminate the Manufacturing Agreement for any reason upon 30-months’ notice. The Company may terminate the Manufacturing Agreement for any reason upon 24-months’ notice, if the Company fails to obtain regulatory marketing approval for abaloparatide upon 12-months’ notice to Lonza, or if abaloparatide is withdrawn from the market upon 12-months’ notice to Lonza. Either party may terminate the Manufacturing Agreement for breach of the agreement, subject to a period in which the breach may be cured, due to a party’s bankruptcy, insolvency, or dissolution, or due to a force majeure event that continues for three months or more.

The Manufacturing Agreement also includes customary provisions relating to, among others, insurance and indemnification, delivery and acceptance procedures, intellectual property, warranties, and confidentiality. Each party’s aggregate liability under the Manufacturing Agreement is limited to the greater of the total amount paid by the Company in the twelve months preceding the last claim or $2.0 million. This limit does not apply to liability arising from fraud, gross negligence, or intentional misconduct, a breach of confidentiality, indemnification by the Company for third-party claims or the Company’s payment obligations.
