 (b) Upon the occurrence of an
Event of Default specified in Sections 4(b) and 4(c), the unpaid principal balance of, and all other sums payable with regard to, this Note shall automatically and immediately become due and payable, in all cases without any action on the part of

number of Warrants of Maker issuable upon the conversion of this Note.

respect to the payment or other provisions of this Note, and agree that additional makers, endorsers, guarantors, or sureties may become parties hereto without notice to them or affecting their liability hereunder.
