If this Agreement is required to be filed by either Party with the Securities and Exchange Commission or another applicable securities regulatory authority, to the extent reasonable, such party shall request confidential treatment for any provisions of this Agreement that the other party believes would disclose trade secrets, confidential commercial or financial information that would impair the value of the contractual rights represented by this Agreement or provide detailed commercial and financial information to competitors or third parties.

9.2. Confidentiality

It is contemplated that in the course of the performance of this Agreement each party may, from time to time, disclose Confidential Information to the other. Each party agrees that any Confidential Information disclosed by either party in accordance with this Agreement shall be maintained in secrecy and each will use all reasonable diligence to prevent disclosure except to personnel and consultants, provided that disclosure to such personnel or consultants is necessary in order to accomplish the purposes for which the Information was disclosed to the receiving party and provided further that such personnel and consultants agree to be bound by the Confidentiality provision of the Agreement. Each party agrees that it will protect and maintain the confidentiality of the Confidential Information that it receives from the other with at least the same degree of care as it uses to protect its own confidential information. Each party hereby further agrees that it will not use the Information for any purpose other than as contemplated by this Agreement.

Any and all Confidential Information received by either party from the other, upon request shall be promptly returned, [*].

It is understood that no patent right or license is hereby granted by this Agreement and that the disclosure of Confidential Information does not result in any obligation to grant either party any right in and to such Information.

Title to the Cubist Technology, Process, and Product (and the intellectual property rights embodied in the Product) shall at all times remain vested in Cubist.

(b) ACSD will implement and conduct the Process but will not research, modify or enhance the Process without authorization from Cubist; provided that in the event Process improvements are realized in implementing and running the Process then ACSD will take all necessary steps to assign, free of charge, ownership of the improvements specific to the Product in Cubist.

(ii) upon written notice to the other party in the event that any bankruptcy, insolvency or receivership proceeding or the like (including out-of-court arrangements involving a party that cannot pay its debts as they mature) is commenced by or against the other party unless, in the case of an involuntary proceeding, it is dismissed within sixty (60) days;

(b) Cubist may terminate this Agreement with notice to ACSD

*Confidential Treatment Requested. Omitted portions filed with the Commission.

Prior to Cubist terminating this Agreement under this Paragraph 12.2(b), but no later than one hundred and eighty days from the applicable Target Date, ACSD will be given reasonable opportunity to present to Cubist a plan of corrective action.

(c) Cubist may terminate this Agreement upon one hundred and eighty (180) days notice to ACSD if Cubist or an affiliate or sublicensee terminates the manufacture or sale of the Product;

(d) Cubist may terminate this Agreement in the event that the FDA does not approve the Product within a commercially reasonable timeframe;

(e) The parties may also terminate this Agreement at any time with one hundred and eighty (180) days notice upon mutual written agreement between Cubist and ACSD.

(a) Upon any termination (including expiration) of this Agreement:

(i) ACSD and Cubist will terminate all tasks being performed pursuant to Section 3 in an orderly manner, as soon as practical and in accordance with a written schedule agreed to by Cubist and ACSD to minimize disruption to customers for the Product;

(ii) All licenses from Cubist to ACSD shall terminate with the exception of those necessary to fulfill ACSD’s obligations to Cubist in accordance with this Section 12.3;

(iii) Each party will return to the other party or certify in writing to the other party that it has destroyed all documents and other tangible items it or its employees or agents have received or created pursuant to this Agreement pertaining, referring or relating to the Confidential Information of the other party, except that each party may retain one (1) complete copy of Confidential Information for use in accordance with Section 8.3(a)(i) for archival purposes to assure compliance with this Agreement; and

(iv) ACSD shall promptly notify Cubist of the quantity of Product in inventory and in production and Cubist shall have the right but not the obligation to purchase such inventory of Product in accordance with the provisions of Sections 5 & 6 or, in the alternative, to direct such other disposition of Product as Cubist specifies. In addition, ACSD will accept orders from Cubist on a C.O.D. basis for additional Product that Cubist is, as of the date of termination notice, contractually obligated to furnish to its customers, if Cubist does not have sufficient Product in its inventory to fulfill such obligations, provided Cubist notifies ACSD of any and all such transactions in writing within 30 (thirty) days of the termination date;

(b) If this Agreement is terminated by Cubist pursuant to Section 12.2(a) or Section 12.2(b), ACSD shall reimburse Cubist for the Premium within thirty (30) days following termination. In all other cases, if termination occurs after the receipt of Product Approvals and Cubist has not recovered the Premium as of the date of termination, Cubist will forfeit the balance of the un-recovered Premium, which shall be considered liquidated damages for Cubist’s early termination of the Agreement;

(c) Termination of this Agreement shall not affect rights and obligations of either party that may have accrued prior to the effective date of termination or any obligation specifically stated to survive termination. The provisions of Sections 1,7,8.5,9,10,11,12,13 and 14 shall survive any expiration or termination of this Agreement.
