ANNEX 2

COMMERCIAL TERMS GOVERNING LICENSE

COMMERCIAL SALE, within 2 (two) months of occurrence of such FIRST COMMERCIAL SALE.

2. Where PRODUCT is sold in a currency other then US Dollars, the rate
of exchange to be used for converting such currency into US Dollars shall be the exchange rate, as published in the Financial Times, at the end of the relevant accounting period. From the second year after FIRST COMMERCIAL SALE of each PRODUCT these
installments must reach at least the annual minimum. These installments will be payable on country by country basis.

3. The payments shall be made within
60 days of the end of calendar quarter, and shall be accompanied by a statement which shall show on a country by country basis for the previous quarter all monies due to the RESEARCHERS. Said sales report shall include the sales figures used to
calculate the royalties due to the RESEARCHERS, as well as the quantities sold, the unit price of any quantity of the PRODUCTS both by SENETEK and its AFFILIATES or SUB-LICENSEES.

4. The royalty properly due to the RESEARCHERS shall in no event be refundable to SENETEK.

5. In the event that SENETEK
shall be required to pay a tax on any payment to the RESEARCHERS, it shall deduct the amount of said tax from the payment due to the RESEARCHERS and shall provide the RESEARCHERS with a copy of the Certificate of the tax having been paid pursuant to
an Agreement on Avoidance of Double Taxation or for other reasons.

6. SENETEK shall prepare accounts, which shall include all the elements necessary to
precisely calculate the NET SALES and NET ROYALTY within the framework of the AGREEMENT. If necessary these accounts shall be made available once a year with 30 days notice to the RESEARCHERS or an accredited designee of the RESEARCHERS during the
term of the AGREEMENT and for one year thereafter. These accounts shall be prepared annually within 90 (ninety) days of the closing date of September 30 of each year which represents the end of SENETEKs fiscal year.

7. Any sums which remain unpaid within the periods set out hereunder shall be subject to interest of 3% (three percent) over above LIBOR as published in the Financial
Times at the end of the relevant accounting period, without prejudice to the RESEARCHERS, right to terminate the contract in accordance with Article 10 of the present AGREEMENT.

8. The RESEARCHERS shall have the right once a year with 30 days notice to audit or have audited the sales accounts kept by SENETEK. Should there be an audit, an expert accountant shall be appointed by mutual
agreement of both PARTIES at the expense of the RESEARCHERS, except that if the amount of installments shown by such audit to be due to the RESEARCHERS exceed the amount actually paid by SENETEK by 5% (five percent), then such expenses shall be paid
by SENETEK and any back payments shall be reimbursed with per the Agreement.
