For purposes of this Section 3, “Cause” shall include: (i) a breach of the terms of this Agreement which is not cured within thirty (30) days of written notice of such default or (ii) the commission of any act of fraud, embezzlement or deliberate disregard of a rule or policy of the Company.

Time Commitment. Danforth will devote such time to perform the Services under this Agreement as may reasonably be required.

Place of Performance. Danforth will perform the Services at such locations upon which the Company and Danforth may mutually agree. Danforth will not, without the prior written consent of the Company, perform any of the Services at any facility or in any manner that might give anyone other than the Company any rights to or allow for disclosure of any Confidential Information (as defined below).

Compliance with Policies and Guidelines. Danforth will perform the Services in accordance with all rules or policies adopted by the Company that the Company discloses in writing to Danforth.

Confidential Information. Danforth acknowledges and agrees that during the course of performing the Services, the Company may furnish, disclose or make available to Danforth information, including, but not limited to, material, compilations, data, formulae, models, patent disclosures, procedures, processes, business plans, projections,

Intellectual Property. Danforth agrees that all ideas, inventions, discoveries, creations, manuscripts, properties, innovations, improvements, know-how, inventions, designs, developments, apparatus, techniques, methods, and formulae that Danforth conceives, makes, develops or improves as a result of performing the Services, whether or not reduced to practice and whether or not patentable, alone or in conjunction with any other party and whether or not at the request or upon the suggestion of the Company (all of the foregoing being hereinafter collectively referred to as the “Inventions”), shall be the sole and exclusive property of the Company. Danforth hereby agrees in consideration of the Company’s agreement to engage Danforth and pay compensation for the Services rendered to the Company and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged that Danforth shall not, without the prior written consent of the Company, directly or indirectly, consult for, or become an employee of, any company which conducts business in the Field of Interest anywhere in the world. As used herein, the term “Field of Interest” shall mean the research, development, manufacture and/or sale of the products resulting from the Company’s technology. The limitations on competition contained in this Section 8 shall continue during the time that Danforth performs any Services for the Company, and for a period of six (6) months following the termination of any such Services that Danforth performs for the Company. If any part of this section should be determined by a court of competent jurisdiction to be unreasonable in duration, geographic area, or scope, then this Section 8 is intended to and shall extend only for such period of time, in such area and with respect to such activity as is determined to be reasonable. Except as expressly provided herein, nothing in this Agreement shall preclude Danforth from consulting for or being employed by any other person or entity.

Non Solicitation. All personnel representing Danforth are employees or contracted agents of Danforth. As such, they are obligated to provide the Services to the Company and are obligated to Danforth under confidentiality, non-compete, and non-solicitation agreements. Accordingly, they are not retainable as employees or contractors by the Company and the Company hereby agrees not to solicit, hire or retain their services for so long as they are employees or contracted agents of Danforth and for one (1) year thereafter. Should the Company violate this restriction, it agrees to pay Danforth

Placement Services. In the event that Danforth refers a potential employee to the Company and that individual is hired, Danforth shall receive a fee equal to fifteen percent (15%) of the employee’s starting annual base salary and target annual bonus. This fee is due and owing whether an individual is hired, directly or indirectly on a permanent basis or on a contract or consulting basis by the Company, as a result of Danforth’s efforts within one (1) year of the date applicant(s) are submitted to the Company. Such payment is due within ninety (90) days of the employee’s start date; provided that hired individual is currently employed at the end of said ninety (90) day period.

No Implied Warranty. Except for any express warranties stated herein, the Services are provided on an “as is” basis, and the Company disclaims any and all other warranties, conditions, or representations (express, implied, oral or written), relating to the Services or any part thereof. Further, in performing the Services Danforth is not engaged to disclose illegal acts, including fraud or defalcations, which may have taken place. The foregoing notwithstanding, Danforth will promptly notify the Company if Danforth becomes aware of any such illegal acts during the performance of the Services. Because the Services do not constitute an examination in accordance with standards established by the American Institute of Certified Public Accountants (the “AICPA”), Danforth is precluded from expressing an opinion as to whether financial statements provided by the Company are in conformity with generally accepted accounting principles or any other standards or guidelines promulgated by the AICPA, or whether the underlying financial and other data provide a reasonable basis for the statements.

Indemnification. Each Party hereto agrees to indemnify and hold the other Party hereto, its directors, officers, agents and employees harmless against any claim based upon circumstances alleged to be inconsistent with such representations and/or warranties contained in this Agreement. Further, the Company shall indemnify and hold harmless Danforth and any of its subcontractors against any claims, losses, damages or liabilities (or actions in respect thereof) that arise out of or are based on the Services performed hereunder, except for any such claims, losses, damages or liabilities arising out of the gross negligence or willful misconduct of Danforth or any of its subcontractors. The Company will endeavor to add Consultant and any applicable subcontractor to its insurance policies as additional insureds. Furthermore, during the Term of this Agreement, Company shall maintain a Crime and Cyber Insurance Policy that includes coverage for “Social Engineering” claims and extends coverage to Danforth.

Independent Contractor. Danforth is not, nor shall Danforth be deemed to be at any time during the term of this Agreement, an employee of the Company, and therefore Danforth shall not be entitled to any benefits provided by the Company to its employees, if applicable. Danforth’s status and relationship with the Company shall be that of an independent contractor and consultant. Danforth shall not state or imply, directly or
