1. Engagement Of Services. Consultant, pursuant to the provisions of this Agreement, is hereby engaged by Cerus to perform services (the “Services”) for Cerus described in Exhibit A attached hereto.

Consultant shall perform Services as requested by Cerus from time to time to the best of Consultant’s ability, such Services to be performed at such place or places and at such times as shall be mutually agreeable to Cerus and Consultant.

In addition to such compensation, Cerus will reimburse the Consultant for travel and other out-of-pocket costs reasonably incurred in the course of performing Services under this Agreement pursuant to Cerus’ current travel and expense reimbursement policies; provided however, that Cerus shall not be obligated hereunder unless: (a) Cerus has agreed in advance to reimburse such costs; and (b) Consultant provides Cerus with appropriate receipts or other relevant documentation for all such costs as part of any submission by Consultant for reimbursement.

3. Independent Contractor. It is understood and agreed that Consultant is an independent contractor and not an employee, agent, joint venturer or partner of Cerus. Consultant agrees not to act as, or give any person any reason to believe that Consultant is, an employee, agent, joint venturer or partner of Cerus.

Consultant is liable for any and all damages incurred by Cerus if and to the extent, such damage is caused by the willful misconduct (opzet) or gross negligence (grove schuld) of Consultant.

Consultant must for its own benefit take out adequate insurances with reputable insurance companies to cover the risk of any damages which may result of its performance of its obligations under this Agreement.

Consultant shall be responsible for the payment of all income tax and any other form of taxation or social security cost in respect of his remuneration or benefits. Consultant shall indemnify the company and hold the company fully harmless in respect of any liability relating to income taxes in relation to the Consultant’s remuneration or benefits.
