Whereas, until the Effective Date of this Agreement, Consultant was an employee of Company and served as its Executive Chairman; and

Whereas, Company and Consultant have agreed that Consultant will resign from, and terminate his employment with, the Company on the Effective Date pursuant to the terms and conditions of a separation agreement (the “Separation Agreement”) and will transition immediately into a consulting role in accordance with the terms of this Agreement;

Wherefore, Consultant and Company agree as follows:

1. Services and Payment. Consultant agrees to undertake and complete the Services, and abide by the terms, set forth in Exhibit A in accordance with and on the schedule specified in Exhibit A. As the only consideration due Consultant regarding the subject matter of this agreement (“Agreement”), Company will pay Consultant in accordance with Exhibit A.

2. Ownership Rights; Proprietary Information; Publicity.

a. Company shall own all right, title and interest (including patent rights, copyrights, trade secret rights, mask work rights, trademark rights and all other intellectual and industrial property rights of any sort throughout the world) relating to any and all inventions (whether or not patentable), works of authorship, mask works, designations, designs, know-how, ideas and information made or conceived or reduced to practice, in whole or in part, by Consultant during the term of this Agreement that relate to the subject matter of, or arise out of, the Services or any Proprietary Information (as defined below) (collectively, “Inventions”) and Consultant will promptly disclose and provide all Inventions to Company. Consultant hereby makes all assignments necessary to accomplish the foregoing ownership. Consultant shall further assist Company, at Company’s expense, to further evidence, record and perfect such assignments, and to perfect, obtain, maintain, enforce, and defend any rights assigned. Consultant hereby irrevocably designates and appoints Company as its agents and attorneys-in-fact, coupled with an interest, to act for and on Consultant’s behalf to execute and file any document and to do all other lawfully permitted acts to further the foregoing with the same legal force and effect as if executed by Consultant.

b. Consultant agrees that all Inventions and all other business, technical and financial information (including, without limitation, the identity of and information relating to customers or employees) Consultant develops, learns or obtains in connection with Services or that are received by or for Company in confidence, constitute “Proprietary Information.” Consultant will hold in confidence and not disclose or, except in performing the Services, use any Proprietary Information. However, Consultant shall not be obligated under this paragraph with respect to information Consultant can document is or becomes readily publicly available without restriction through no fault of Consultant. Upon termination and as otherwise requested by Company, Consultant will promptly return to Company all items and copies containing or embodying Proprietary Information, except that Consultant may keep its personal copies of its compensation records and this Agreement. Consultant also recognizes and agrees that Consultant has no expectation of privacy with respect to Company’s telecommunications, networking or information processing systems (including, without limitation, stored computer files, email messages and voice messages) and that Consultant’s activity, and any files or messages, on or using any of those systems may be monitored at any time without notice.

c. As additional protection for Proprietary Information, Consultant agrees that (i) until one year after the Effective Date of this Agreement, Consultant will not directly solicit any employee or consultant of Company to leave Company for any reason, and (ii) during the period that he is providing Services to the Company, (A) Consultant shall not engage in any activity with any organization in the field of robotically controlled flexible catheters for Electrophysiology or Vascular medical procedures and Consultant will not assist any other person or organization in competing or in preparing to compete in the field of robotically controlled flexible catheters for Electrophysiology or Vascular medical procedures and (B) Consultant will not accept employment with or directly or indirectly provide any type of services for Intuitive Surgical, Inc., Corindus Inc., or Catheter Robotics, Inc. to the extent such employment or services would compete with Hansen’s present or anticipated business. Consultant will notify Company within five (5) business days if and when Consultant accepts full time employment, and shall provide the identity of the full-time employer and the time employment with that company commenced.

d. To the extent allowed by law, Section 2.a and any license to Company hereunder includes all rights of paternity, integrity, disclosure and withdrawal and any other rights that may be known as or referred to as “moral rights,” “artist’s rights,” “droit moral,” or the like. To the extent any of the foregoing is ineffective under applicable law, Consultant hereby provides any and all ratifications and consents necessary to accomplish the purposes of the foregoing to the extent possible. Consultant will confirm any such ratifications and consents from time to time as requested by Company. If any other person provides any Services, Consultant will obtain the foregoing ratifications, consents and authorizations from such person for Company’s exclusive benefit.

e. If any part of the Services or Inventions is based on, incorporates, or is an improvement or derivative of, or cannot be reasonably and fully made, used, reproduced, distributed and otherwise exploited without using or violating technology or intellectual property rights owned or licensed by Consultant and not assigned hereunder, Consultant hereby grants Company and its successors a perpetual, irrevocable, worldwide royalty-free, non-exclusive, sublicensable right and license to exploit and exercise all such technology and intellectual property rights in support of Company’s exercise or exploitation of the Services, Inventions, other work performed hereunder, or any assigned rights (including any modifications, improvements and derivatives of any of them).

4. Former or Conflicting Obligations. Consultant represents and warrants to the Company that Consultant will not disclose to the Company, or use, or induce the Company to use, any proprietary information or trade secrets of others. Consultant represents that Consultant’s performance of services under this Agreement will not breach any agreement not to compete with others or any agreement to keep in confidence proprietary information acquired by Consultant in confidence or in trust prior to the effective date of this Agreement. Consultant certifies that Consultant has no outstanding agreement or obligation that is in conflict with any of the provisions of this Agreement, or that would preclude Consultant from complying with the provisions hereof.

9. Miscellaneous. Any breach of Section 2 or 3 will cause irreparable harm to Company for which damages would not be an adequate remedy, and therefore, Company will be entitled to injunctive relief with respect thereto in addition to any other remedies.
