6. TERMINATION

6.1 A party (“Terminating Party”) may, by written notice of default to the other party (“Terminated Party”), (i) terminate this Agreement, in whole or in part, including any Order Forms or SOWs (a) if the Terminated Party materially breaches this Agreement, and the Terminated Party does not cure such material breach within thirty (30) calendar days after receipt of written notice of such breach; or (b) immediately following the failure to resolve the suspension of business, insolvency, institution of bankruptcy, liquidation proceedings by or against the Terminated Party, appointment of a trustee or receiver for the Terminated Party’s property or business, or any assignment, reorganization or arrangement by the Terminated Party for the benefit of its creditors; or (c) immediately upon a material breach of Section 2 (License) by the Terminated Party, or (ii) terminate any individual Order Form or SOW if the Terminated Party fails to perform any provision of such Order Form or SOW and does not cure the breach within thirty (30) calendar days after receipt of written notice thereof.

Notwithstanding anything to the contrary herein, Confidential Information shall be deemed to include the Ariba Products, the terms and conditions of this Agreement (including pricing), and either party’s technical and business information relating to inventions or software, research and development, future product specifications, implementation methodologies, engineering processes, costs, profit or margin information, and marketing and future business plans. The parties agree, unless required by law, not to use or make each other’s Confidential Information available to any third party for any purpose other than as necessary to perform under this Agreement. Recipient shall protect the Confidential Information of Discloser by using the same degree of care, but no less than a reasonable degree of care, that it uses to protect its own confidential information of a like nature to prevent its unauthorized use, dissemination or publication by its employees or agents. Both parties acknowledge that any breach of its obligations with respect to Confidential Information may cause the other irreparable injury for which there are inadequate remedies at law and that Discloser shall be entitled to seek equitable relief in addition to all other remedies available to it. Customer shall not disclose the results of any performance tests of the Ariba Products to any third party without Ariba’s prior written approval. A party’s Confidential Information shall not include information that: (i) is or becomes publicly available through no act or omission of Recipient; (ii) was in the Recipient’s lawful possession prior to the disclosure and was not obtained by Recipient either directly or indirectly from the Discloser; (iii) is lawfully disclosed to the Recipient by a third party without restriction on Recipient’s disclosure, and where Recipient was not aware that the information was the confidential information of Discloser; (iv) is independently developed by the Recipient without violation of this Agreement; or, (v) which is disclosed by Recipient

as needed to comply with a court order, subpoena, or other government demand (provided that Recipient first notifies Discloser and gives Discloser the opportunity to challenge such court order, subpoena, or government demand).

10. TRADEMARKS

Neither party grants the other party any rights to use its trademarks, service marks, or other proprietary symbols or designations (“Trademarks”) without the written consent of the other party, except as otherwise described herein. Neither party will combine the other’s Trademarks so as to effectively create a unitary composite mark, nor shall it use any product name or trademark in a manner that is confusingly similar to the other party’s Trademark.

11. INTENTIONALLY LEFT BLANK.

12. AUDIT

Customer agrees to allow a mutually acceptable independent certified public accountant to audit and analyze the Customer’s compliance with the terms of this Agreement. Any such audit shall be permitted by Customer within thirty (30) days of Ariba’s written request and shall be performed during normal business hours at times mutually agreed upon by Customer and Ariba. Audits shall be made no more frequently than once every twelve (12) months, and shall not unreasonably interfere with Customer’s business activities. If an audit should reveal a discrepancy between the Fees owed Ariba and the Fees actually paid by Customer, Customer will promptly pay the difference. In the event an audit should establish an underpayment of greater than ten percent (10%) of payments owed Ariba for any particular period, Customer shall be responsible for reimbursement of all reasonable, verifiable costs related to the performance of the subject audit (collectively, “Audit Costs”).

13. FORCE MAJEURE

Neither party shall be liable to the other for failure or delay in the performance of a required obligation if such failure or delay is caused by riot, fire, flood, earthquake, natural disaster, electronic virus, electronic attack or infiltration, internet disturbance, government act or other similar cause beyond such party’s (the “Affected Party”) control (collectively, a “Force Majeure Event”), provided that Affected Party gives prompt notice of such condition, uses reasonable efforts to resume its full performance as soon as possible, and provided further that the other party (the “Non-Affected Party”) may terminate the affected Order Form or SOW if such condition continues for a period of one hundred eighty (180) days. During the Force Majeure Event, the Non-Affected Party may similarly suspend its performance obligations, until such time as the Affected Party resumes its performance obligations.

14.2 The parties hereto are and shall remain independent contractors, and nothing herein shall be deemed to cause this Agreement to create an agency, partnership, or joint venture between the parties hereto.

14.12 This Agreement may be executed simultaneously in two or more counterparts, each of which will be considered an original, but all of which together will constitute one and the same instrument. For clarification purposes, the dates contained in the signature blocks of this Agreement

or any documents executed pursuant to this Agreement only indicate the date(s) upon which such document was signed, and shall have no effect on any other term of this Agreement.
