Such replacement Note (resulting from the partial conversion) shall be delivered to the Holder prior to the close of the fifth (5^th) Business Day after the applicable Conversion Date.

(ii) The Borrower agrees to provide notice to the Holders of any event or issuance that would result in any adjustment to the Conversion Price pursuant to this Section 4(d) and such notice shall specify the new Note Conversion Price in effect.
