2.1.1 Third Party Supply. The above notwithstanding, in the event Biocon has (i) supplied Par with [] kg lots of API; and (ii) developed capacity to provide at least [] kg per year of API to Par, Biocon may sell API to Optimer Pharmaceuticals or its respective designees for sale outside the Territory. In the event Biocon is unable to meet its supply requirements for API to Par and Optimer Pharmaceuticals or its respective designees Biocon shall first and preferentially supply Par with all if its API requirements before supplying any API to Optimer Pharmaceuticals or its respective designees. Furthermore, any supply agreement for API entered into between Optimer Pharmaceuticals or its respective designees and Biocon shall clearly state that Biocon’s supply obligations to such party is secondary and inferior to Biocon’s obligations to supply Par with API.

2.2 Exclusive Purchase Requirements.

API DEVELOPMENT AND DEVELOPMENT COMMITTEE

5.1 Development. Biocon shall use Commercially Reasonable Efforts to develop a commercially viable method of producing API. At a minimum, Biocon shall, as of the Commercial Launch in the USA, have developed the capacity to produce not less than [] kg per year of API (“Commercial Supply of API”). In the event Par determines that its API requirements per year will be in excess of [] kg per year, the Parties may, at their discretion, negotiate in good faith to raise Biocon’s production capacity above [***] kg per year of API.

5.3 Development Costs. With the exception of Section 5.3.1 below, all costs of developing a Commercial Supply of API shall be borne entirely by Biocon.

5.3.1 If during development of the Commercial Supply of API Biocon discovers that there is a need for a substantial capital investment for installing a down-streaming and recovery

facility for meeting Par’s supply requirements for this molecule (the “Facility”), then in this event, Biocon may request from Par an amount, not to exceed [] dollars ($[]), for the out-of-pocket expenses it actually incurs for this capital investment. Such a request may only be made before January 1, 2007 and shall include a good faith list and budget of possible out-of-pocket expenditures that may be incurred in completing the Facility. In the event Biocon makes such a request, Par shall have the right to inspect the Facility and receive copies of all invoices regarding the cost of the Facility.

(a) conform in all respects to the API Specifications and Quality Agreement (defined below);

(b) be manufactured in conformity with cGMP;

(d) conform with all applicable material requirements of any and all Product Approvals granted for the Products within the Territory; and

(e) meet any other material current pharmacopoeia or regulatory requirements of all relevant Regulatory Authorities in the Territory.

6.1.1 Packaging. Biocon shall ensure that each batch of API is labeled and each of the batch numbers is applied to each batch, as required by the applicable Regulatory Authorities. Biocon shall use Commercially Reasonable Efforts to provide Par with API with a minimum shelf life, before any retest, of [] ([]) months from the date of delivery to Par. Due to the current the lack of stability data for the API, the Parties agree to negotiate in good faith more definite stability parameters to be included in the Quality Agreement (defined below). In the event such provision in the Quality Agreement regarding API stability conflicts with or is inconsistent with this Agreement, that provision in the Quality Agreement shall govern and control. Biocon shall ensure that a copy of the Certificate of Analysis (as defined in the Quality Agreement) with respect to each batch of API supplied to Par accompanies each batch. Biocon will also ensure that all documentation reasonably required by Par shall be made available to Par upon request.

6.1.2 Shipment and Storage. Biocon shall provide and maintain suitable storage and transport conditions for each batch of API and shall provide Par with complete written instructions with respect to proper conditions for the transport and storage of API. Upon receipt of any batch of API by Par from Biocon, Par shall provide and maintain suitable storage conditions therefore and shall comply with any written instructions provided by Suppler that are required by the DMF in respect of the transport and storage of API.

Biocon agrees to provide access to its facilities during and otherwise facilitate this audit process. Par shall also have the right, upon reasonable prior notice, to have a Par employee or qualified external consultant present at Biocon’s manufacturing facility as an observer during the production of the API. Biocon also agrees to allow any relevant Regulatory Authority to inspect any of its facilities used in fulfilling its obligations under this Agreement with respect to the Product.

6.4 Nonconforming API. Par may reject any shipment of API as defective if the API does not conform to Biocon’s obligations under Section 6.1 and/or the Biocon’s product warranties set forth Section 9.2 or which is adulterated or misbranded within the meaning of the Act. In order to reject a shipment, Par must: (i) give notice to Biocon of Par’s intent to reject such shipment together with a written indication of the reasons for such possible rejection within forty five (45) days after delivery of the API to Par, or in the case of latent defects, within forty-five (45) days after the date that Par discovers the defect and (ii) as promptly as reasonably possible thereafter, provide Biocon with notice of final rejection (a “Rejection Notice”) and the full basis therefore.

The results of such evaluation shall be binding upon the Parties. The Party that is determined to have been incorrect in its determination of whether the API should be rejected shall pay the costs of any such evaluation. If the fees of the independent laboratory or consultant are due in advance, then Biocon shall pay such fees; provided, however, that promptly after the independent laboratory or consultant completes its evaluation, Par shall the reimburse the Biocon such fees if Par was incorrect in its determination.

6.4.2 If any shipment is rejected by Par, Par’s duty to pay all amounts payable to Biocon in respect to the rejected API shall be suspended unless and until there is a determination by an independent laboratory or consultant in support of Biocon’s Objection Notice in accordance with Section 6.2.1.

6.4.3 Whether or not Biocon accepts Par’s basis for its notice of rejection, Biocon shall use reasonable efforts, at Par’s request, to provide replacement API, which shall be purchased by Par as provided in this Agreement.

Biocon shall give notice and supply copies to Par of all communications between Biocon and any Regulatory Authority relevant to the production of API.

6.6 API Specifications. Changes to the API Specifications may only be made in accordance with the procedure delineated in the Quality Agreement, that notwithstanding, in no case may a change to the API Specifications be made upon less than eighteen (18) months prior written notice to Par and without Par’s written consent, which shall not be unreasonably withheld, unless such change is of the nature that does not require a filing with, approval by or notification to, any Regulatory Authority. Biocon agrees that it will promptly notify Par of any and all changes to the API Specifications and/or manufacturing process.

6.7 DMF. Par may, at it discretion, request that Biocon file a DMF related to production of API. If, and only if, Par makes such a request, Biocon shall properly file a DMF related to the API with the FDA. Prior to the filing of a DMF related to the production of API, Biocon shall submit such filing for Par’s review and approval. Biocon shall maintain all applicable DMFs during the Term of this Agreement. In the event Biocon does file a DMF, Biocon agrees to promptly provide Par and/or Par’s designee with a letter of access to such applicable DMFs for the API. Biocon agrees that it shall not file a DMF related to production of API unless specifically asked by Par, in writing, to file such a DMF. If a DMF is filed, changes to the DMF may only be made in accordance with the procedure delineated in the Quality Agreement, that notwithstanding, in no case may a change to the DMF be made upon less than eighteen (18) months prior written notice to Par and without Par’s written consent, which shall not be unreasonably withheld, unless such change is of the nature that does not require a filing with any Regulatory Authority.
