Appendix A

Draw Reconciliation Plan

This Draw Reconciliation Plan applies to the first twelve (12) months following the Company’s commercial launch (the “Initial Commercial Year”). During the Initial Commercial Year, the first $100,000 you earn in commissions pursuant to a commission plan approved by Company management will not be subject to Draw reconciliation. All commissions earned in excess of $100,000, however, will be offset by the Draw you accrued prior to the Company’s commercial launch, in accordance with the following graduated schedule;

Draw reconciliation will begin once your year-to-date commissions in the Initial Commercial Year exceed $100,000. For example, and as illustrated by the schedule above, the first $10,000 in commissions earned in excess of $100,000 will be subject to the following split: 25% of it (i.e., $2,500) will go to you and 75% of it (i.e., $7,500) will go to the Company in repayment of your Draw. Once you have earned $50,000 in commissions over $100,000, your commissions will be subject to the following split until the Draw is fully repaid or the Initial Commercial Year comes to an end, whichever is sooner; 75% of the commissions will go to you and 25% of the commissions will go to the Company.

At the conclusion of the Initial Commercial Year, if you have not earned any commissions in excess of $100,000, then the Company will forgive the entire Draw. Otherwise, the Company will forgive whatever amount of the Draw remains outstanding at the end of the Initial Commercial Year.

Agreed and Accepted:
