Capitalized terms used but not defined in this letter agreement ("Letter") have the respective meanings set forth in the Note. The Company, the Parent and the Holder hereby agree as follows: 1. Amendment. Subject to the execution by the Company, the Parent and the --------- holders of the Other Notes of letters in identical form and substance to this Letter, the Note is hereby amended by adding the following subsections (f) and (g) at the end of Section 3 thereof: "(f) Payment in Lieu of Conversion Above Number of Common Shares Available --------------------------------------------------------------------- for Resale under the Registration Statement. If at any time while this ------------------------------------------- Note is outstanding, the Holder delivers a Conversion Notice and, on the date of receipt of such Conversion Notice by Vasogen (the "Conversion Notice Date"), following the application of, when applicable, Section 3(e) hereof, the number of Common Shares that Vasogen would otherwise be required to issue pursuant to the foregoing provisions of this Section 3 to satisfy such conversion in full (the "Required Conversion Shares") exceeds the number of Common Shares that are available for resale under the Registration Statement (as defined in the Registration Rights Agreement) (such excess, the "Unregistered Shares" and the difference between the Required Conversion Shares minus the Unregistered 2 Shares, the "Available Shares"), then (A) the Company shall direct Vasogen to, and upon such direction Vasogen shall or shall cause the Transfer Agent to, issue to the Holder the Available Shares by the third (3rd) Trading Day following receipt of the applicable Conversion Notice and (B) the Company shall pay to the Holder, in lieu of Vasogen issuing Unregistered Shares and in addition to any Conversion Make-Whole amount required to be paid pursuant to Section 3(e), within twelve (12) Trading Days following the Conversion Notice Date in cash an amount equal to the product of (x) the Unregistered Shares multiplied by (y) (1) in the event the Holder has not received an Unavailability Notice (as defined below) prior to the delivery of its Conversion Notice, 105% of the arithmetic average of the Weighted Average Price of the Common Shares during the period beginning on, and including, the day the Holder delivers its Conversion Notice and ending on, and including, the third (3rd) Trading Day following receipt of such Conversion Notice or (2) in the event the Holder has received an Unavailability Notice prior to delivery of such Conversion Notice, 105% of the Weighted Average Price of the Common Shares on the applicable Conversion Date (the "Unregistered Shares Redemption Payment"); provided, however, that if at any time the arithmetic average of the Weighted Average Price of the Common Shares calculated for the applicable period or day in accordance with clause (1) or (2) is less than $1.00, then for purposes of clause (y) such arithmetic average shall be multiplied by 110% instead of 105% to determine the Unregistered Shares Redemption Payment. In the event that the Company and Vasogen receive a Conversion Notice from more than one holder of Notes for the same Conversion Date and the Available Shares can cover some, but not all, of such portions of the Notes submitted for conversion, Vasogen shall allocate the Available Shares amongst the converting holders in accordance with Section 3(c)(iv). Provided that Vasogen delivers the Common Shares and makes the Unregistered Shares Redemption Payment in the time periods set forth in clauses (A) and (B) of the foregoing sentence, the obligations of the Company and Vasogen with respect to such Conversion Notice shall be deemed to be fully satisfied and the Holder shall have no right to pursue any remedies set forth in Section 3(c)(ii) hereof with respect to such Conversion Notice. (g) Notice of Unavailability of Common Shares Under the Registration ---------------------------------------------------------------- Statement. The Company or Vasogen shall deliver to the Holder a written --------- notice (an "Unavailability Notice") that there are no additional Common Shares available for resale under the 3 Registration Statement (the "Unavailability Date") at the earlier of (i) no more than one (1) Trading Day after such Unavailability Date or (ii) no more than one (1) Trading Day after the delivery of any Conversion Notice by a Holder requiring a conversion of a number of Required Conversion Shares in excess of the amount of any Available Shares." 2.
