WHEREAS, MannKind and AFP entered into the Agreement pursuant to which AFP is to manufacture and supply the Product to MannKind, and MannKind is to purchase certain minimum quantities of the Product;

WHEREAS MannKind and AFP, together with Amphastar, the parent company of AFP, have determined it to be mutually beneficial to amend the Agreement as set forth herein.

NOW, THEREFORE, for good and valuable consideration, MannKind and AFP, together with Amphastar, hereby agree to amend the Agreement as follows:

2.2 For avoidance of doubt, Amphastar shall assume all of AFP’s rights and obligations under the Agreement.

2.3 With respect to Amphastar’s obligations under the Agreement, Amphastar either shall perform, or shall cause AFP to perform, all such obligations under the Agreement.

2.4 Section 4.4 of the Agreement is amended and replaced in its entirety with the following:
