Consulting Agreement

This CONSULTING AGREEMENT is made this first day of April, 2005, by and
between Senetek PLC, a company organized under the laws of England with its principal place of business at 620 Airpark Road, Napa, California 94558 (Senetek and, together with its subsidiaries, the Company) and Wade H.
Nichols, an individual residing at 1390 St. James Court, St. Helena, California 94574 and 42 Crestview Lane, P.O. Box 751, Sagaponack, New York 11962 (Consultant).

The Consultant has served as a senior executive officer of the Company and in connection with the termination of the Consultants employment the
Company wishes to fix the terms upon which it may avail itself, if desired, of the Consultants future services.

Accordingly, in
consideration of the mutual promises set forth herein, Senetek and Consultant hereby agree as follows:

1. Consulting Services. Until
such time, if any, as the Consultant may commence full-time employment with another employer, and subject to the Consultants prior business or personal commitments, the Consultant agrees to provide services within the areas of his prior
involvement as a senior executive upon the Companys request (the Consulting Services). The Consulting Services shall be performed personally by Consultant, unless Senetek shall otherwise agree in any particular case, provided
however that Consultant may assign this Agreement to a wholly-owned company which will provide for Consultants personal services. The Consulting Services shall be performed at such place or places and at such time or times as Senetek may
reasonably request, subject to Consultants prior business and personal commitments.

2. Consulting Term. The term of this
Agreement (the Term) shall commence as of May 1, 2004 and shall continue until terminated by either party upon thirty (30) days written notice.

3. Consulting Fee; Expense Reimbursement. For legal and licensing-related Consulting Services performed from the Consultants home office,
the Company shall pay fees to Consultant at the rate of U.S.$200 per hour. For Consulting Services away from the Consultants residence, the Company shall pay a fixed fee of U.S.$1,000 per day. The Consultant shall submit invoices for
Consulting Services not more frequently than monthly, and the Company shall pay fees within thirty (30) days after invoice date. In addition, the Company shall reimburse Consultant for reasonable out-of-pocket expenses incurred with
Seneteks prior approval in rendering Consulting Services (including reasonable travel, hotel and meal expenses, temporary living expenses if approved by Senetek in advance and telecommunications, postage, photocopy and other like expenses).
The Company shall reimburse consulting expenses monthly within thirty (30) days of Consultant submitting an itemized statement of expense reimbursement due, with original receipts attached for expenses in excess of $25. All payments hereunder
shall be by direct deposit into the bank account in which the Consultants salary checks were deposited during the period of his employment, until such time as the Consultant



---

specifies a different bank account for such purpose. Consultant shall be solely responsible for payment of any and all
income taxes due with respect to Consultants receipt of all amounts paid hereunder. Consultant acknowledges that the Consulting fees and expense reimbursement provided for hereunder are the only compensation to which Consultant or any other
party shall be entitled, by contract or otherwise, in consideration of providing the Consulting Services.

4. Confidentiality. In
connection with furnishing Consulting Services, Consultant agrees to comply with all of the provisions of the form of Confidentiality and Non-Disclosure Agreement annexed hereto with respect to Confidential Information of Senetek to the same extent
as if he were a Recipient signatory thereto.

5. Status of Parties. Consultant acknowledges that Consultants
status, as respects the Company and any third parties with which Consultant may come in contact in connection with furnishing Consulting Services, is that of a consultant and independent contractor and not an officer, employee or agent of the
Company. Consultant agrees not to hold himself out as or represent himself as being, in performing Consulting Services or otherwise, authorized to make any representation or commitment on behalf of the Company or any statement to representatives of
the general, business or scientific press on behalf of or for attribution to the Company, whether or not for publication.

6. Governing
Law and Jurisdiction. This Agreement shall be governed by and construed and enforceable in accordance with the laws of the State of California, and the parties irrevocably submit to the exclusive jurisdiction of the courts of that State for the
resolution of any disputes hereunder.

IN WITNESS WHEREOF, the parties have caused this Agreement to be signed as of the day and year first
set forth above.
