Page 8 (b) If Connetics gives [*], Miza may invoice Connetics for, and Connetics shall be required to pay to Miza an amount equal to [*] of the amount owed under the purchase order, calculated in accordance with EXHIBIT B; provided, however, that Miza must use Commercially Reasonable Efforts to reallocate the suite to manufacture another product on the originally scheduled date, and no charge shall be assessed to Connetics if such efforts are successful. (c) If Connetics gives [*] Miza may invoice Connetics for, and Connetics shall be required to pay to Miza an amount equal to [*] of the amount owed under the purchase order, calculated in accordance with EXHIBIT B; provided, however, that Miza must use Commercially Reasonable Efforts to reallocate the suite to manufacture another product on the originally scheduled date, and no charge shall be assessed to Connetics if such efforts are successful. (d) If Connetics gives [*] of cancellation, Miza may invoice Connetics for, and Connetics shall be required to pay, an amount equal to [*] of the amount owed under the purchase order, calculated in accordance with EXHIBIT B. 3.11 Shipment; Inspection; Rejection (a) Shipment of Product. Miza shall ship, or cause to be shipped at Connetics' expense, the Product to Connetics or such destination(s) as Connetics may designate in writing. Delivery of Product to a common carrier authorized by Connetics shall constitute delivery to Connetics, and risk of loss shall pass to Connetics at that time. Miza agrees to provide support to assist Connetics to pursue any Product related claims it may have against carriers, provided that Connetics shall reimburse Miza for any out-of-pocket expenses Miza may incur in providing such support. All invoices and other shipping documents shall be sent by first class mail or by fax to Connetics' address for notices under this Agreement, directed to the attention of Controller. (b) Non-Conforming Product. Connetics may reject any batch of Product that does not conform to the Manufacturing Standards, subject to the terms of this Section and the Quality Agreement. Within ten (10) business days after Miza's internal release of Product, Connetics shall inspect the Product and notify Miza whether it will accept or reject the Product. No inspection under this Section shall relieve Miza of its obligations and warranties under this Agreement. If Connetics rejects all or any part of any shipment of Product, the procedures to be followed are: (i) Connetics shall submit to Miza in writing any claim that Product does not conform with the Product Specifications or cGMPs, accompanied by a report of Connetics' analysis (which analysis - ------- * Certain information on this page has been omitted and filed separately with the Commission. Confidential treatment has been requested with respect to the omitted portions. Page 9 shall be conducted in good faith) and a sample of the Product at issue, explaining in reasonable detail the basis on which the allegedly nonconforming Product does not meet the Product Specifications. Once nonconformance is confirmed and fault is determined to belong with Miza pursuant to the provisions of this Section 3.11(b), Connetics shall not be obligated to pay for such nonconforming shipment of Product. Only those tests listed in the Product Specifications may be used to demonstrate nonconformance of Product. (ii) Miza shall conduct its own analysis of the sample in good faith within thirty (30) days after the receipt by Miza of the report and sample from Connetics, and provide the results to Connetics. (A) If after Miza's own analysis of the sample Miza agrees with the claim of nonconformity, Connetics shall promptly inform Miza if Connetics wishes to have Miza replace the nonconforming Product with conforming Product. If Connetics wishes to receive such replacement Product, Miza shall provide such replacement as soon as reasonably practicable thereafter, in which case Connetics shall be obligated to pay only for such replacement Product. Connetics shall not be obligated to pay for the nonconforming Product, and Miza shall: (1) credit Connetics for the amount paid by Connetics to Miza for the nonconforming Product if Connetics has already paid for such nonconforming Product or (2) cancel its invoice to Connetics for such nonconforming Product if Connetics has not yet paid for such nonconforming Product, and Connetics shall not be obligated to pay such canceled invoiced amount. (B) If, after its own analysis, Miza does not agree with the claim of nonconformity or determines that Connetics is responsible for the nonconformity, such Product shall be tested for conformance with the applicable Product Specifications by an independent third party testing laboratory mutually acceptable to both parties. The independent analysis shall be binding on both Parties solely for the purpose of determining whether such Product may be rightfully rejected. (iii) After a final determination that the Product shipment is nonconforming, and if Miza is responsible for the nonconformity, Connetics shall return or destroy it at Miza's request and cost in the most cost effective and environmentally safe and appropriate Page 10 manner available, consistent with federal, state and local laws and regulations. (iv) If conforming Product supplied under this Agreement becomes nonconforming or unsuitable at no fault of Miza, Connetics will remain obligated to pay Miza for such Product. At Miza's request, Connetics shall return such unsuitable Product to Miza. Otherwise, Connetics shall destroy it in the most environmentally safe and appropriate manner available, consistent with federal, state and local laws and regulations. (c) Notwithstanding the other provisions of this SECTION 3.11, Connetics shall have no right to reject any Product that fails to conform with the Manufacturing Standards if the nonconformance is attributable to (i) events outside of Miza's control that occurred after delivery to a common carrier, or (ii) processes, procedures or Product components specified or approved in writing by Connetics in the Product Specifications or otherwise, provided that Miza followed or used such processes, procedures and Product components materially in accordance with the Product Specifications. 3.12 Unique Materials. Connetics shall reimburse Miza for its actual costs expended for the purchase of "Unique Materials" (i.e., certain raw materials, artwork, printed cans, labels, cartons and special valves) purchased by Miza expressly to meet its performance obligations under this Agreement in reliance upon a firm Purchase Order pursuant to SECTION 3.4 and which later are made obsolete, or to the extent that such Unique Materials remain on hand at the expiration of this Agreement as provided under SECTION 10.1. For purposes of this Section, material is obsolete if it cannot be incorporated into the Product due to changes mandated by a Regulatory Authority, changes directed by Connetics, or Connetics-mandated cancellation or postponement. Once material becomes obsolete, Miza may invoice Connetics for the acquisition costs of such obsolete material from time to time, which invoices shall identify the material in question and shall be accompanied by a reasonably detailed statement of the cause of such obsolescence and a certification that Miza has disposed of such materials in accordance with the terms of this Agreement. 3.13 Risk of Loss. Risk of loss of Product shall be with Miza until delivery of Product to a common carrier pursuant to SECTION 3.11 of this Agreement. Notwithstanding the forgoing, Miza shall not be liable for loss of Product caused by an event of force majeure or Connetics' negligence or willful misconduct. 3.14 Insurance. Miza shall at its own expense obtain and maintain workers' compensation and comprehensive general liability insurance with respect to performance under this Agreement, in amounts reasonably determined by Miza, but in no event less than [*]. - ------- * Certain information on this page has been omitted and filed separately with the Commission.

Miza shall submit to Connetics an invoice five (5) days after Miza's internal release of Product. Connetics shall make payment of each invoice within 45 days after receipt by Connetics. If within thirty (30) days after the delivery of Product and the accompanying Certificate of Analysis to Connetics, Connetics demonstrates non-conformance under SECTION 3.11 and Miza agrees with such finding, Connetics shall not be obligated to pay for such non-conforming shipment. 4.3 Most Favored Vendor. Miza agrees that the price charged to Connetics at all times during the term of this Agreement shall be Miza's lowest price for equivalent quantities and lead times, to the extent offered to third parties in the same marketplace. 4.4 Currency. Amounts due to Miza under this Agreement are payable in U.S. Dollars. 4.5 Annual Performance and Price Reviews.
