Aptose Biosciences Appoints Dr. Bradley Thompson to the Audit Committee

SAN DIEGO and TORONTO, Jan. 20, 2015 /CNW/ - Aptose Biosciences Inc. (NASDAQ: APTO, TSX: APS), a clinical-stage company developing new therapeutics and molecular diagnostics that target the underlying mechanisms of cancer, announced today that Dr. Bradley Thompson has been appointed to the Audit Committee, and that the NASDAQ Stock Market ("NASDAQ") has notified the Company it has regained compliance with Listing Rule 5605 to maintain three independent members on the Audit Committee.

On December 15, 2014, Dr. Brian Underdown, a member of the Board of Directors and Audit Committee, resigned from the Aptose Board of Directors in conjunction with the appointment of Dr. Erich Platzer to the Board. This left the Audit Committee with only two independent members until Dr. Bradley Thompson was formally appointed to the committee. As previously reported on January 15, 2015 in the Company's 6K filing with the Securities and Exchange Commission, on January 13, 2015 the Company received, as expected, a notification letter from NASDAQ stating that the Company no longer complied with NASDAQ's audit committee requirements of maintaining committee membership by at least three independent directors as set forth in Listing Rule 5605 due to the resignation of Dr. Brian Underdown,  which was previously reported on December 15, 2014, in its Form 6-K filing with the Securities and Exchange Commission. The NASDAQ letter was issued in accordance with standard NASDAQ procedures.

Consistent with Listing Rule 5605(c)(4), NASDAQ provided the Company a cure period in order to regain compliance as follows:

• until the earlier of the Company's next annual shareholders' meeting or December 15, 2015; or
• if the next annual shareholders' meeting is held before June 15, 2015, then the Company must evidence compliance no later than June 15, 2015.

On January 16, 2015 the Company appointed Dr. Bradley Thompson to the Audit Committee and was notified by NASDAQ today that the Company has regained compliance with Listing Rule 5605.
