Dear Sirs:

Organon, a Dutch company (“Organon”) with its principal office and place of business at Xxxxxxxxxxxxxx 0, 0000 XX XXX, Xxx Xxxxxxxxxxx (each of MannKind and Organon, a “Party” and together, the “Parties”).

A dispute has arisen between the Parties relating to the Supply Agreement (the “Dispute”). The Parties have settled their differences and have agreed terms for the full and final settlement of the Dispute. They wish to record those terms of settlement (including the termination of the Supply Agreement), on a binding basis, in this letter agreement (“Letter Agreement”).

Agreed terms

1.		Interpretation
		Capitalised terms used but not defined in this Letter Agreement shall have the meaning given to them in the Supply Agreement.
2.		Effect of this Letter Agreement
		The Parties hereby agree that this Letter Agreement shall immediately be fully and effectively binding on them.
3.		Payment, Delivery and Acceptance
3.1		The Supply Agreement is terminated. Notwithstanding such termination, the provisions of the Supply Agreement explicitly referred to herein, as well as all provisions designated to survive termination pursuant to Section 11.5 of the Supply Agreement, shall survive this termination and remain in effect.
3.2		MannKind shall pay to Organon the total sum of US$16 million, divided into two installments payable by way of bank transfer as follows:
		(a) the amount of US$8 million to be paid within two days of MannKind’s receipt of the First Shipment (as defined in Section 3.3(a) below); And
		(b) the amount of US$8 million to be paid within two days of MannKind’s receipt of the Second Shipment (as defined in Section 3.3(b) below).

3.3		Organon shall manufacture and supply to MannKind’s Danbury, Connecticut facility a total of [...***...] of Product manufactured in accordance with the shelf life requirements of the Supply Agreement and divided into two shipments deliverable as follows:
		(a) A shipment of approximately [...***...] of Product to arrive at MannKind’s Danbury, Connecticut Facility on 28 June 2011 (the “First Shipment”); and
		(b) A shipment of the balance of the total of [...***...] of Product to be shipped from Organon’s facility in France as soon as practicable following Organon’s receipt of the payment from MannKind pursuant to Section 3.2(a) above (the “Second Shipment”). Organon shall deliver the Second Shipment to MannKind’s Danbury, Connecticut facility as soon as practicable following such Second Shipment’s having received all regulatory, customs, or FDA clearances required for shipment into and within the United States, provided, however, that Organon shall provide MannKind reasonable notice in advance of the planned delivery date and provided further that such delivery date shall be extended as necessary to ensure that delivery does not occur on any statutory holiday, a weekend, a Monday or a Friday. To facilitate Organon’s delivery obligations under this Section 3.3(b), MannKind hereby agrees to provide Organon with a Letter of Intended Use in the form attached hereto as Schedule A and revised by MannKind as may be necessary in order to meet government/regulatory requirements. For the avoidance of doubt, it shall be MannKind’s obligation to provide a Letter of Intended Use that satisfies all government/regulatory requirements.

3.6		The provisions of clause 6.4 (“Inspection, Acceptance and Rejection”) and clause 6.5 (“Expert”) of the Supply Agreement shall apply to each delivery of Product under this Letter Agreement.
3.7		Product supplied by Organon hereunder shall conform to the Specification set forth in Exhibit A to the Supply Agreement and the warranty set forth in clause 3.8 of this Letter Agreement. Organon shall perform quality control testing and quality oversight on the Product to be delivered to MannKind hereunder.
3.8		Organon represents and expressly warrants that the Product provided under this Letter Agreement shall conform to the Specifications, including the Quality/Technical Agreement, shall be in compliance with all applicable laws and regulations, and free from defect, claim, encumbrance or lien. If and to the extent the corresponding event is not governed by clause 3.6 of this Letter Agreement, upon any breach of the warranty Organon shall at Organon’s sole expense promptly (and in no event longer than ninety (90) calendar days) correct, at no cost to MannKind, and at MannKind’s request, any such breach by replacement of the Product that did not conform to such warranty and shall provide technical assistance to MannKind to address the Product non-conformity issues. Any replacement shall be considered a new Product for purposes of this clause 3.8.
		Organon represents and warrants that it has and shall at all times throughout the term of this Agreement have, whether by right, title, interest, including by license or otherwise, the Intellectual Property Rights that are required to use, manufacture, market, offer to sell, sell, import and export the Product in accordance with the terms of this Letter Agreement and that this Letter Agreement shall not infringe third party rights.
