Hi Harry,

Sorry to have let this slip through the cracks at the end of last week…

Yes, please use this email as confirmation that I agree to extend the Term until May 5th, 2017, unless this Agreement is terminated as provided in Section 8…

You’ve done a fantastic job in the acting CFO role – let’s keep it going!

Thanks,

Subject:Consulting Agreement- Palmin- A2

Hi Chris,

My Consulting Agreement is expiring on November 5th. The First Amendment (attached) states that: “The Company and Consultant may subsequently extend the term in six month increments by mutual written agreement via email.” I would be happy to do so.

Please confirm via return email that you agree to extend the Term until May 5, 2017, unless this Agreement is terminated as provided in Section 8 (see attached Agreement). Then, this email will serve as the Second Amendment to the Agreement.

Let me know if you would like to discuss. Thank you,

Harry
