1. Services as Corporate Secretary. Hillsberg hereby agrees to serve as the corporate Secretary of Duska and Duska Scientific. Hillsberg will work on a part-time basis for Duska and Duska Scientific (i.e., not greater than a total of 10 hours per month for both companies) and will report to the President or Chief Executive Officer of Duska and Duska Scientific, respectively. The services set forth in this Section 1 shall be rendered by Hillsberg in Los Angeles, California and at such times and, if required in particular circumstances, through business trips to such other locations as reasonably requested by the Board of Directors of Duska or Duska Scientific, respectively. The duties of Hillsberg will be those customarily performed by a corporate Secretary of an emerging bio-pharmaceutical public company.

2. Compensation and Benefits.

2.1 Fees. In consideration of the services to be rendered to Duska and Duska Scientific hereunder, Duska shall pay to Hillsberg $2,0833.33 per month, paid on the 15^th day of each month this Agreement is in effect.

2.2 Expenses. Duska and Duska Scientific shall reimburse Hillsberg for necessary and reasonable out-of-pocket business expenses incurred by Hillsberg in the performance of this Agreement in accordance with the reimbursement policies of Duska or

However, Hillsberg will be eligible for so long as he serves on the Board of Directors of Duska or Duska Scientific to receive all of the benefits made available by the respective companies to their directors for such service.

2.4 Withholding; Indemnification. Hillsberg shall have full responsibility for applicable withholding taxes for all compensation paid to him under this Agreement, and for compliance with all applicable labor and employment requirements with respect to his self-employment, sole proprietorship or other form of business organization. Hillsberg agrees to indemnify, defend and hold Duska and Duska Scientific harmless from any liability for, or assessment of, any claims or penalties with respect to such withholding taxes, labor or employment requirements, including any liability for, or assessment of, withholding taxes imposed on Duska or Duska Scientific by the relevant taxing authorities with respect to any compensation paid to Hillsberg.

3. Term and Termination.

In the event the Board of Directors of Duska determine to re-elect Hillsberg to serve as the corporate Secretary of Duska or Duska Scientific, respectively, at the first annual meeting of the stockholders of Duska after the Effective Date, then this Agreement shall be deemed to be extended until the next annual meeting thereafter of Duska’s shareholders. This Agreement and Hillsberg’s rights and obligations hereunder shall, under any of the following circumstances, terminate in advance of the time specified in this Section 3, and Hillsberg shall have the right to receive only its fees that shall be accrued hereunder or under any other agreement between Duska or Duska Scientific and Hillsberg through the effective date of such termination and shall have no right to receive any further compensation hereunder from and after the time of such termination:

3.1 Termination by Duska. In the event that Hillsberg shall become either physically or mentally incapacitated so as to be incapable of performing his duties as required hereunder, and if such incapacity shall continue for a period of 45 consecutive days, Duska may, at its option, terminate this Agreement and Hillsberg’s duties hereunder by written notice to Hillsberg at that time or at any time thereafter while such incapacity continues. Duska may terminate this Agreement for Cause (as hereinafter defined) at any time upon written notice to Hillsberg. “Cause” as used in this Agreement means that (i) Hillsberg has materially breached any of the terms or conditions of this Agreement and has failed to correct such breach within 15 days following written notice from Duska or Duska

2

Scientific, respectively, of such breach, or (ii) Hillsberg has been charged with a felony or has committed or participated in any intentionally fraudulent act that materially damages, or may materially damage, the business or reputation of Duska or Duska Scientific, respectively.

3.2 Termination by Hillsberg. Hillsberg may terminate this Agreement at any time upon 30 days prior written notice to Duska and Duska Scientific.

4. Independent Contractor. Hillsberg’s relationship with Duska and Duska Scientific will be that of an independent contractor and not that of an employee of Duska or Duska Scientific.

6. Indemnity. Hillsberg agrees to indemnify and hold Duska and Duska Scientific, respectively, harmless from and against any and all claims, demands, causes of action, losses, damages, liabilities, costs, and expenses, including attorneys’ fees, arising from a breach of any of Hillsberg’s representations and warranties herein or attributable to or resulting from his willful misconduct in fulfilling its duties pursuant to this Agreement. Hillsberg warrants and represents that he has full power and authority to enter into and perform this Agreement, and that his performance of this Agreement shall not violate any other agreement to which he is a party. Duska and Duska Scientific agree, jointly and severally, to indemnify and hold Hillsberg harmless from and against any and all claims, demands, causes of action, losses, damages, liability, costs and expenses, including attorneys’ fees arising out of Hillsberg’s fulfillment of his duties pursuant to this Agreement, other than those arising from Hillsberg’s breach of any of his representations and warranties hereunder or his willful misconduct.

All work performed and all materials developed or prepared for Duska or Duska Scientific by Hillsberg in rendering the services pursuant to this Agreement are the property of Duska or Duska Scientific, respectively, and all title and interest therein shall vest in Duska or Duska Scientific, respectively, and shall be deemed to be works made for hire and made in the course of the services rendered hereunder. To the extent that title to any such works may not, by operation of law, vest in Duska or Duska Scientific, respectively, or such works may not be considered works made for hire, all rights, title and interest therein are hereby irrevocably assigned to Duska or Duska Scientific, respectively. All such materials shall belong exclusively to Duska or Duska Scientific, respectively, and Duska or Duska Scientific, respectively, shall have the right to obtain and to hold in its own name copyrights, trademarks, patents, other registrations, or such other protection as may be appropriate to the subject matter, along with any extensions and renewals thereof.
