The Agreement will continue in effect on a product-by-product and country-by-country basis until the expiration of the obligation to make payments under the Agreement with respect to such product in each country, unless earlier terminated by either party pursuant to its terms. Either the Company or Hengrui Pharma may terminate the Agreement upon mutual agreement or for the other party’s insolvency or certain uncured material breaches. The Company may terminate the Agreement for any reason upon certain notice to Hengrui Pharma.
