3.1Exclusive Right to Manufacture. SDS, on and subject to the terms and conditions contained herein and in the 3-Way Agreement, hereby grants to Chembio, and Chembio hereby accepts from SDS, without acknowledging or agreeing to its necessity with respect to the HIV Barrel Product, a worldwide exclusive license to manufacture the HIV Barrel Products for resale by Inverness under the 3-Way Agreement or, in the event of termination of the 3-Way Agreement, as otherwise set forth herein.

3.2Technology. Subject to Article 4, the Parties will give each other access to their respective know-how and Technology relevant to the HIV Barrel Product and any New HIV Barrel Products in order to optimize manufacturing processes and quality and reduce manufacturing costs.

3.3Patent Validity. Chembio, having investigated and analyzed the SDS Patents, hereby acknowledges that each of the SDS Patents is valid and enforceable.

(a) Chembio agrees not to (and to cause its Affiliates not to) Challenge Patent Rights in the SDS Patents, or to assist any Third Party in doing so.

(b) SDS agrees not to (and to cause its Affiliates not to) Challenge any Patent Rights included in the Chembio IP or to assist any party in doing so, unless such Patent Rights are enforced or threatened to be enforced against SDS or an SDS customer or partner for infringement resulting from an SDS product or service other than a product in the Barrel Field that diagnoses or detects HIV or HIV infection which SDS product or service is sold in violation of this Agreement or the 3-Way Agreement. SDS further agrees not to challenge Chembio’s right to continued use for manufacture of the HIV Barrel Product of the Confidential Information or Technology utilized by Chembio in the manufacture of the HIV Barrel Product.

(c) Neither Party has investigated the Confidential Information or Technology utilized by the other party in connection with the manufacture of the HIV Barrel Product, and nothing contained herein shall be construed as an admission by either Party that such Confidential Information or Technology is or is not covered by the SDS Patents or the Chembio IP.

(i) terminate this Agreement or terminate any or all rights and licenses granted to the Challenging Party hereunder, and

Without limiting the generality of the foregoing, the Parties will consider (through the JOC) use of a Third Party manufacturer if significant cost savings can be achieved, as long as such Third Party manufacture is in compliance with applicable regulations, will not impair quality obligations or cause a material change in registrations or product approvals.

5.3Manufacturing Failures Under the 3-Way Agreement.
