Likewise, all correspondence, reports, records, charts, advertising materials and other similar data and documents pertaining to the business, customers, activities or future plans of the Company or its affiliates which is in the Employee’s possession, custody or control, whether prepared by the Employee or others, shall be delivered promptly to the Company (within 24 hours) without request by the Company upon termination of Employee's employment.

5.Indemnification. In the event Employee would incur any expense or liability in connection with any threatened, pending, contemplated or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by the Company or its affiliates against Employee) (“Proceeding”), any appeal to such a Proceeding, any inquiry or investigation that could lead to a Proceeding, by reason of the fact that Employee is or was performing services under this Agreement or by reason of the fact that Employee is an officer of the Company, then the Company shall indemnify Employee against all expenses (including reasonable attorneys' fees and costs), judgments, fines, and amounts paid in settlement, as actually and reasonably incurred by Employee in connection therewith. In the event that both Employee and the Company are made a party to the same third-party action, complaint, suit or Proceeding, the Company agrees to engage counsel, and Employee agrees to use the same counsel, provided that if counsel selected by the Company shall have a conflict of interest that prevents such counsel from representing Employee, Employee may engage separate counsel and the Company shall pay all reasonable attorneys' fees of such separate counsel. The Company shall not be required to pay the fees of more than one law firm except as described in the preceding sentence and shall not be required to pay the fees of more than two law firms under any circumstances. Further, while Employee is expected at all times to use Employee's best efforts to faithfully discharge Employee's duties under this Agreement, Employee cannot be held liable to the Company for errors or omissions made in good faith, and Employee will be indemnified as described above, except where Employee has exhibited gross, willful and wanton negligence and misconduct or performed criminal and fraudulent acts which materially damage the business of the Company. The indemnification provided under this Section 5 is non-exclusive and shall in no way limit any indemnification provided by applicable law or any indemnification provision of the Company’s, Genesis’ or Genesis Marine’s charter or organizational documents.

6.No Prior Agreements. Employee represents and warrants that to Employee’s knowledge Employee has no obligations, legal, in contract, or otherwise, inconsistent with the terms of this Agreement or with Employee’s undertaking employment with the Company to perform the duties described herein. Employee will not disclose to the Company or any of its affiliates, or use, or induce the Company or any of its affiliates to use, any confidential, proprietary, or trade secret information of others. Employee represents and warrants that to Employee’s knowledge, Employee has returned all property and confidential information belonging to all prior employers, if Employee is obligated to do so. Employee agrees to indemnify the Company

for any Proceeding, including, but not limited to, all expenses (including reasonable attorneys' fees and costs), judgments, fines, and amounts paid in settlement, as actually and reasonably incurred by the Company in connection therewith, including any investigation of the same, by any such third party that such third party may now have or may hereafter come to have against the Company based upon or arising out of any non-competition agreement, invention or confidential information, trade secret or secrecy agreement or like agreement between Employee and such third party which was in existence as of the date of this Agreement, should the third party prevail in such proceeding against the Company.

7.Entire Agreement.    This agreement constitutes the entire agreement between the parties and supersedes any prior understandings, agreement or representations by or between the parties (other than those contained in any confidentiality or non-compete agreement dated as of the date hereof between Employee and the Company or one of its affiliates), written or oral, to the extent they have related in any way to the subject matter hereof.

8.Assignment; Binding Effect. Employee understands that Employee has been selected for employment by the Company on the basis of Employee's personal qualifications, experience and skills.
