(b) Payment Default. This Contract, and the parties’ duties and obligations hereunder, may be terminated by Seller upon Buyer’s failure to make payment under any undisputed portion of any invoice on the due date for such invoice and Buyer’s failure to cure such delinquency within ten (10) days following receipt of written notice thereof from Seller to Buyer. Seller may not withhold performance or term this Contract if Buyer disputes any invoice or portion of any invoice in good faith and fails to pay such invoice while the dispute is pending. Buyer may withhold payment in whole or part of any amount due or claimed by Seller to such extent as may be necessary to protect Buyer or its Affiliates from loss on account of defective Systems or Services, third party claims arising from Seller’s performance under this Contract, failure of Seller to make payments promptly to employees, suppliers and contractors, exceptions through audits or liabilities of Seller to Buyer under this Contract.

(c) Termination for Cause. Either party may terminate this Contract at any time during Term, upon forty-five (45) days prior written notice to the other party, if the other party materially breaches any term or condition of this Contract (other than a payment default under Section 9(b)) and fails to cure such breach within the forty-five (45) day cure period. As used in this Contract, a “material breach” shall mean a material misstatement or omission in any representation or warranty of a party, or a breach or default in the performance of any agreement, covenant or obligations of a party hereto which, in any such case, deprives the non-breaching party of a material right or benefits in any material respect.

(d) Termination for Patent Cause. If Seller’s U.S. Letters Patent Number 5,396,074 is determined to be invalid or unenforceable by a final non-appealable judgment of a court of competent jurisdiction, then Buyer shall have the right, but not the obligation, to terminate this Contract upon thirty (30) days’ written notice to Seller.

(e) Effect of Termination. In the event of termination, both parties shall be liable for all obligations that accrued prior to termination, including completion of deliveries under any open Statement of Work unless the non-breaching party elects not to have the open Statement of Work completed, and for all obligations that survives the termination or expiration of this Contract.

Seller shall be responsible for obtaining and maintaining all necessary plan inspection standards and plant licenses, registrations or permits to enable the manufacture and sale of the Systems. Each party will promptly notify the other party of any comments, responses or notices that a party receives from any governmental authorities which relate to the regulatory status of the Systems in any applications or fields other than the irradiation of food, flowers or animal hides.

(c) Buyer’s Inspections. Buyer and its designees and Affiliates shall have reasonable access to observe and inspect Seller’s manufacturing facilities and procedures, including manufacturing operations, at reasonable intervals and upon reasonable notice to Seller. Seller shall maintain proper and accurate records of all manufacturing steps, processes, quality assurance and quality control procedures and will provide reasonable access to Buyer from time to time at reasonable intervals and upon Buyer’s reasonable request.

11. Confidentiality

(a) Non-Disclosure. The parties anticipate that both Buyer and Seller may learn Confidential and Proprietary Information (as defined below) of the other as a consequence of the transactions contemplated by this Contract. The parties therefore agree, on behalf of themselves, their agents, employees, parents, subsidiaries, officers, directors, and all other persons acting on or for their behalf, (i) to keep all Confidential and Proprietary Information confidential and not to disclose such Confidential and Proprietary Information, either directly or indirectly, to any third party, and (ii) not to use any such Confidential and Proprietary Information for any purpose other than performance of this Contract or as otherwise authorized under the License Agreement without the prior written consent of the non-disclosing party.

(b) Exceptions. The obligations in this Section 11 shall not apply to any: (i) information that either party knows about the other prior to the execution of this Contract except any information which is the subject of unexpired confidentiality obligations; (ii) information that is publicly known, or becomes publicly known, through no breach by either party; (iii) information that is rightfully obtained by either party from any third party who has no duty of confidentiality under this Contract; (iv) information that is independently developed by or for a receiving party completely apart from the disclosures hereunder, (v) information that is released pursuant to a binding court order or government regulation, provided that the receiving party delivers a copy of such order or action to the other party and reasonably cooperates with the other party if it elects to contest such disclosure or seek an appropriate remedy such as a protective order or (vi) is otherwise necessary to disclose in order to file or prosecute patent applications, prosecute or defend litigation or comply with applicable law, including regulatory filings, or otherwise establish rights or enforce obligations under this Contract, but only to the extent that any such disclosure is reasonably necessary.

(c) Precautions. The parties mutually agree to take all reasonably necessary steps, and to prepare and execute all necessary documents, to protect and prohibit the disclosure of Proprietary and Confidential Information under this Section 11 using the higher of a reasonable standard of care or the care used by such party to protect its own confidential or proprietary information. Each party will immediately notify the other party of any information that comes to its attention which might indicate that there has been a loss of confidentiality with respect to such other party’s Confidential and Proprietary Information.

(d) Remedies. In the event of a breach or threatened breach by either party of such party’s confidentiality obligations in this Section 11, the parties acknowledge and agree that it would be difficult to measure the damage to the non-breaching party from such breach, that injury to such non-breaching party from such breach would be impossible to calculate and that money damages would therefore be an inadequate remedy for such breach. Accordingly, the non-breaching party, in addition to any and all other rights which may be available, shall have the right of injunctive relief and other appropriate equitable remedies to restrain any such breach or threatened breach.

(e) Return of Property. Upon request, each party shall immediately return to the other party the originals and all copies of any Confidential and Proprietary Infofll1ation of the other party.

If any Work does not meet the definition of “work made for hire,” Seller agrees to irrevocably assign, and hereby does irrevocable assign and transfer, to Buyer all of its Intellectual Property Rights therein, or if such assignment is not allowed, hereby grants to Buyer and its Affiliates a worldwide, exclusive, irrevocable, perpetual royalty-free, fully paid license, with right to sublicense through multiple tiers of sublicenses, to modify or use the Works for any and all purposes other than the irradiation or pasteurization of food, flowers or animal hides. All worldwide rights, title and interest in any and all trade secrets and know-how discovered or developed by any employee or consultant of Seller in the course of performing its obligations under a Statement of Work, excluding trade secrets relating to irradiation or pasteurization of food, flowers or animal hides, shall be held and owned exclusively by Buyer

(the “Trade Secrets”), and Seller hereby irrevocably assigns and transfers the Trade Secrets to Buyer. To the extent that any provision regarding Intellectual Property Right to the Systems delivered under this Contract is contrary in the License Agreement, the provision of the License Agreement shall control.

13. Remedies

The remedies of the parties contained in this Contract are cumulative with one another and with any other remedies which the parties may have at law, in equity, under any Contracts of any type or otherwise, and the exercise or failure to exercise any remedy shall not preclude the exercise of that remedy at another time or of any other remedy at any time. No waiver of a breach of any provision of this Contract shall constitute a waiver of any other breach or of such provision. The invalidity in whole or in part of any condition of this Contract shall not affect the validity of other conditions.
