Conversion Rate” means 60% of the lowest VWAP for the fifteen (15) consecutive Trading Days ending on the Trading Day

that the Holder fails to meet its funding requirements as set forth in the Purchase Agreement, within ten (10) calendar days (unless
waived by the Company).”

(f) in the definition of “Equity Conditions” in each of the Notes is hereby amended and restated in its entirety as
follows:


 


“(f) on any date that
the Company desires to make a payment of interest and/or principal, the conversion price for such payment will be the lower of
the Fixed Conversion Price or 60% of the lowest daily volume weighted average price (“VWAP”) in the fifteen (15) trading
days prior to such date of payment; provided, that the Fixed Conversion Price shall apply in the event that the Holder fails to
timely meet its funding requirements as set forth in the Purchase Agreement (unless waived by the Company).”


 


1.3The
first sentence of Section 2(e) of each of the Notes is hereby amended and restated in its entirety as follows:

six (6) month anniversary of the Closing Date or the Effective Date, the Company shall redeem this Note and any accrued but unpaid

1.4The
last sentence of Section 2(e) of each of the Notes is hereby amended and restated in its entirety as follows:


 


“For example, if the
Amortization Payments commence on the sixth (6th) month anniversary date from the Original Issue Date, the Company shall begin
to make equal bi-weekly amortization payments of 1/13th the total principal and interest due on this Note, in cash or, subject
to the Equity Conditions, Common Stock (at the Company’s option).”
