(e) The Company has taken commercially reasonable precautions (i) to protect its rights in its Intellectual Property and (ii) to maintain the confidentiality of its trade secrets, know-how and other confidential Intellectual Property, and to the Company's knowledge, there have been no acts or omissions (other than those made based on reasonable, good faith business decisions) by the officers, directors, shareholders and employees of the Company the result of which would be to materially compromise the rights of the Company to apply for or enforce appropriate legal protection of the Company's Intellectual Property. (f) Except for matters which will not have a Company Material Adverse Effect, all of the Company's Intellectual Property has been created by employees of the Company within the scope of their employment by the Company or by independent contractors of the Company who have executed agreements expressly assigning all right, title and interest in such Intellectual Property to the Company, and no portion of the Company's Intellectual Property was otherwise jointly developed with any third party. 3.14.

Exhibit C sets forth a list of contracts described in clauses (a), (d), (e), (f), (g) and (h) above. The Company has delivered to the Purchasers copies of such of the foregoing agreements (or an accurate summary of any oral agreement) to the extent requested. All of such agreements and contracts are valid, binding and in full force and effect, in accordance with their respective terms as to the Company and, to the knowledge of the Company, as to each other party thereto. Neither the Company, nor, to the Company's knowledge, any other party to such agreements is in default of any of its obligations under any of the agreements or contracts listed on Exhibit C, in a manner which could have a Company Material Adverse Effect. 3.16. Compliance; Merger Discussions.

There is no term or provision of any mortgage, indenture, contract, agreement or instrument to which the Company is a party or by which it is bound, or, to the best of the Company's knowledge, of any provision of any state or federal judgment, decree, order, statute, rule or regulation applicable to or binding upon the Company, which materially adversely affects or, so far as the Company may now foresee, in the future is reasonably likely to result in or have a Company Material Adverse Effect. To the best of the Company's knowledge, none of the employees of the Company is in violation of any material term of any contract or covenant (either with the Company or with another entity) relating to employment, patents, assignment of inventions, proprietary information disclosure, non-competition or non-solicitation.

Absence of Changes. Since the Balance Sheet Date, there has been no material adverse change in the business, prospects, condition (financial or otherwise), or results of operations of the Company, other than changes occurring in the ordinary course of business (which ordinary course changes have not, individually or in the aggregate, had a Company Material Adverse Effect); provided, however, that the Purchasers acknowledge that the Company has continued to incur losses since the Balance Sheet Date. - 8 - 13 3.18.
