Item 8.01 Other Events.

On August 03, 2012, we entered into a stipulation of settlement that will resolve (i) the state derivative lawsuits consolidated under the caption In re MannKind Corporation Derivative Shareholder Litigation, Case No. BC454931, pending in the Superior Court of California, County of Los Angeles (the “State Derivative Action”), and (ii) the federal derivative lawsuits consolidated under the caption In re MannKind Corp. Derivative Litigation, Case No. 11-cv-05003-GAF-SSx, pending in the United States District Court, Central District of California (the “Federal Derivative Action”). We refer to the State Derivative Action and the Federal Derivative Action collectively as the Derivative Actions. The current and former employees and directors named as individual defendants in the Derivative Actions have also entered into the stipulation of settlement. By entering into the stipulation of settlement, defendants do not in any way admit fault or liability, and continue to deny all allegations of wrongdoing arising out of the Derivative Actions. The stipulation of settlement, a copy of which is filed as Exhibit 99.1 hereto, remains subject to preliminary and final approval by the U.S. District Court.

If the settlement is approved preliminarily by the U.S District Court, our stockholders will be notified of the proposed settlement and the procedure by which they can object to the settlement. The settlement will then be subject to final approval by the U.S. District Court.

Subject to final approval of the settlement by the U.S. District Court, and in exchange for a release of all claims by the plaintiffs, among others, and a dismissal of the Derivative Actions, we have agreed (i) to adopt certain corporation governance measures, (ii) to cause our insurers to pay the plaintiffs’ attorneys a total of $800,000, and (iii) to issue plaintiffs’ attorneys 225,000 shares of our common stock. Following final approval of the settlement by the U.S. District Court, the shares will be issued pursuant to an exemption from registration provided by Section 3(a)(10) of the Securities Act of 1933, as amended.
