in the courts or before the administrative agencies of the Territory or otherwise, and to make promptly available to Airspan, its Distributors, and attorneys all of Distributor's files, records, and other information pertaining to the advertising, promotion, and sale of the Airspan Products. All assistance requested by Distributor in this paragraph shall be at AIRSPAN's expense. This Expense includes costs, attorneys' and consultants' fees, and reimbursement of time spent by officers, agents and employees of Distributor. 9.7 Distributor agrees and undertakes that it will not at any time, whether during the term of this Agreement or after its expiration or termination, adopt, use, or register without Airspan's prior, written consent any work or symbol or combination thereof which is similar to any of the Trademarks. 9.8 In the advertising and sale of Airspan Products, Distributor may use the Trademarks in relation to those Airspan Products. Distributor will not make or permit the alteration or removal of any tags, labels, or other identifying marks placed by Airspan on Airspan Products. Distributor will not use or give any third party permission to use the Trademarks. Distributor will not use, or give any third party permission to use, the names "Airspan Communications Ltd.", "Airspan Networks Incorporated", "ACL", "ANI" or abbreviations or derivations thereof in Distributor's corporate titles, or in any way which might result in confusion as to Airspan and Distributor being separate and distinct entities. Distributor admits Airspan's exclusive ownership of the name "Airspan Networks Incorporated", "Airspan Communications Ltd.", "ANI", "ACL", and any abbreviations or derivations thereof and all of Airspan's Trademarks (whether registered or not). Distributor shall not take any action inconsistent with Airspan's ownership of such Trademarks; therefore, Distributor shall treat all of Airspan's items distinctively (as to typography) and shall only use exact reproductions of all Airspan's symbols (including Airspan's logo). Distributor shall not adopt or use any Trademark or product name which may be confusingly similar to any Airspan Trademark. Distributor may use the Airspan logo as it appears on Airspan's letterhead. 10.

Without limitation, Confidential Information includes: (1) Airspan's software products, materials, data reports, programs, documentation, diagrams, and all related technical information; (2) all information relating to Airspan's business and products which is critical to Airspan's position in the marketplace, including future plans of Airspan relating to the fields of endeavor in which Distributor performs services for Airspan, the nature of certain work projects to which Distributor is exposed, and the identity of persons working on those projects; and (3) any improvements, enhancements, or modifications to the above made by or on behalf of Airspan during the performance under this Agreement which are provided, made available, or disclosed by or on behalf of Airspan to Distributor, or used by Airspan or any of Airspan's other Distributors in connection with their own sales activities. 10.2 Trade secrets are confidential information that includes ideas, concepts, techniques, processes, inventions, knowledge, and know-how developed by Airspan which: (1) derives independent economic value, actual or potential, from not being generally known to, and not being readily ascertainable by proper means by, other persons who can obtain economic value from its disclosure or use; and (2) is subject to the efforts of Airspan that are reasonable under the circumstances to maintain its secrecy. (This "trade secret" language comes from the Uniform Trade Secrets Act.) 10.3 Distributor covenants and agrees that it will use the Confidential Information solely for the performance of services under this Agreement, and shall not disclose such Confidential Information to any other person (including Airspan employees in any other division, group, or entity), firm, or corporation. 10.4 Distributor shall use the same degree of care in safeguarding the Confidential Information as it uses for its own confidential information of like importance, but no less than reasonable care. Upon discovery of any disclosure or misuse of Confidential Information, Distributor shall endeavor to prevent any further disclosure or misuse. 10.5 All Confidential Information shall remain the property of Airspan, and such Confidential Information and all copies thereof shall promptly be returned to Airspan upon
