(b) After successfully completing formulation, bioavailability and delivery work for the first indication of Pharmaceutical Uses, DAS shall use commercially reasonable efforts to develop two (2) additional indications of Pharmaceutical Uses. DAS shall be obligated to commence development of the second such indication within two (2) years of commencing development of the first indication. Subject to DAS's reasonable determination of the commercial viability of a third indication and Abbott's rights under SECTION 4.3(c) below, DAS shall be obligated to commence development of the third such indication within two (2) years of commencing development of the second indication. For purposes of this SECTION 4.3(b), development of an indication shall be deemed to have commenced upon enrollment of the first subject in the first clinical study for an indication using the formulation selected for clinical development. (c) In the event DAS breaches a material obligation under this Agreement or under a Work Plan, Abbott may then advise DAS that Abbott believes that DAS has breached such material obligation and that Abbott is adversely impacted thereby. Upon so advising DAS, Abbott may initiate an alternative dispute resolution procedure ("ADR") as set forth in EXHIBIT C, and request the ADR to rule upon whether DAS has breached any such material obligation. In the event that the neutral party to such ADR renders a ruling that DAS has breached such material obligation and that Abbott was adversely impacted thereby, and DAS fails to comply with the terms of the neutral's ruling within the time specified therein for compliance, or if such compliance cannot be fully achieved by such date, DAS has failed to commence compliance and/or has failed to use diligent efforts to achieve full compliance as soon thereafter as is reasonably possible, then Abbott's sole remedy shall be (i) the right to terminate this Agreement and the licenses granted hereunder, and to obtain from DAS a license to Improvements under SECTION 4.8; or (ii) if, at the time Abbott initiates the ADR, the ADR only alleges DAS's failure to develop the Product for some, but not all of those indications, then Abbott shall only be entitled to a partial termination of this Agreement and the licenses granted hereunder as to those Product indications for which failure to develop is alleged and determined by the ADR, and shall obtain from DAS a license to Improvements under SECTION 4.8 as to Improvements only with respect to such Product indications, with no effect on DAS's rights hereunder for those Product indications and Improvements that the [******] Confidential Treatment Requested.

In the event that DAS elects not to market in a particular country(ies), either directly or through third parties, Abbott shall have the right, upon notice to DAS, to market, either directly or through third parties, the Product in each such country, by paying to DAS the same royalty to which Abbott would otherwise be entitled if DAS was marketing the Product in such country. DAS agrees to provide Product to Abbott for sale in each such country at the same cost (as evidenced by DAS's internal records) incurred by DAS in procuring or manufacturing Product for its own sales. If there is any material disagreement between the parties concerning whether commercially reasonable efforts towards commercialization have been made with respect to a particular indication after Regulatory Approval in a country, then the matter may be submitted to ADR where remedies for failure to expend such efforts could include a requirement to expend additional efforts to make up for any failures, damages and/or termination of the license rights in the applicable country, unless DAS chooses to undertake such activities and expenses as needed to correct the failure. 4.5 MARKETING: DAS shall have sole responsibility for marketing Product, including entering into any co-marketing and/or co-promotion arrangements. DAS shall distribute all Product samples in the United States in accordance with the Prescription Drug Marketing Act. 4.6 MANUFACTURING: DAS and its Affiliates shall have sole responsibility for manufacturing Product or having Product manufactured for it by a third party manufacturer.
