PART III - NARRATIVE State below in reasonable detail the reasons why the Form 10-K, 11-K, 10-Q, N-SAR, or the transition report or portion thereof, could not be filed within the prescribed time period. Calypte Biomedical Corporation (the "Registrant") is still awaiting documentation in order to properly prepare a complete and accurate Form 10-Q. The Registrant has been unable to receive this data in a timely manner without unreasonable effort and expense. For the foregoing reasons, the Registrant requires additional time in order to prepare and file its quarterly report on Form 10-Q for the quarter ended March 31, 2003. The Registrant anticipates that it will have all necessary information required to complete and file its Form 10-Q within five (5) calendar days of the date hereof. PART IV - OTHER INFORMATION (1) Name and telephone number of person to contact in regard to this notification Joseph A. Baratta 212 750-9700 ------------------- --- -------- (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 answer is no, identify report(s). [X] Yes [ ] 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. Revenues for the first quarter of 2003 totaled $784,000, compared with $1,159,000 for the comparable period in 2002. The net loss attributable to common stockholders for the first quarter of 2003 was $6,374,000, or $0.04 per common share, compared with a net loss attributable to common stockholders of $678,000, or $0.02 per common share, for the three months ended March 31, 2002. The net loss for the first quarter of 2003 included $3,587,000 in non-cash charges that were related to the grants of common stock and options and warrants as compensation for services and non-cash interest expense related primarily to the accounting for Registrant's convertible debt financing instruments. During the quarter ended March 31, 2002, non-cash charges and credits were a net credit of $1,292,000, related primarily to the gain on settlement of debt. The change in revenue from the quarter ended March 31, 2002 as compared to the quarter ended March 31, 2003 can be attributed in part to the announcement made by the Registrant last fiscal year of its intention to wind down its operations. In anticipation of the wind down last year, many of the Registrant's customers in turn increased their order rates as a contingency in the event of a cessation of Registrant's operations and non-availability of Registrant's products. The Company subsequently restarted its operations and the Registrant's post-restart revenue for quarter ended March 31, 2003 did not reflect the uncharacteristically higher order rate reflected in the March 31, 2002 revenues.
