(Attach extra sheets if needed.) The CFO resigned as of May 15, 2005 and more time is required to complete the necessary work. Part IV -- Other Information (1) Name and telephone number of person to contact in regard to this notification: William J. Driscoll ( 720 ) 488-1711 - ------------------------------------------------------------------------------- (Name) (Area Code) (Telephone Number) (2) Have all other periodic reports required under section 13 or 15(d) of the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of 1940 during the preceding 12 months or for such shorter period that the Registrant was required to file such report(s) been filed? If the answer is no, identify report(s). [ X ] Yes [ ] No No (3) Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof? [ X ] Yes [ ] No

If so: attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made. We expect losses significantly in excess of prior periods due to several factors including 1) commencement of commercial operations; 2) the addition of personnel to support the operations of the company; and 3) the impairment of goodwill in relation to the purchase of the 19% minority interest of the subsidiary; and 4) other expenditures relating to settlement of the minority shareholder. We estimated that the loss for the nine months ended March 31, 2005 will be approximately $(12,600,000) as compared to $(183,681) for the same period of 2004. The significant expenditures include a $9,000,000 charge for impairment of goodwill generated as a result of the March 2005 settlement with the former minority shareholder of the subsidiary, interest expense of $1,324,733 because of a greater amount of indebtedness outstanding during the period, $650,000 for the contribution of 200,000 shares of LTI's Series A common stock to Lifeline Orphan Foundation and expenses relating to the substantially greater activities in which LTI engaged during the period since the completion of the October 2004 reorganization. Lifeline Therapeutics, Inc. has caused this notification to be signed on its behalf by the undersigned thereunto duly authorized. Dated this 16th day of May, 2005 By: /s/ William J.
