Collabrium Japan Acquisition Corporation (the “Company”) receiveda notification letter from the Listing Qualifications Department of The Nasdaq Stock Market LLC (“Nasdaq”) on October 3, 2013 indicating that the Company is not currently in compliance with Nasdaq’s Listing Rules (“Listing Rules”) for continued listing due to the Company’s failure to file with the Securities and Exchange Commission under Report of Foreign Private Issuer on Form 6-K (“Form 6-K”) an interim balance sheet and income statement as of the end of its most recently completed second quarter (March 31, 2013) as required by Listing Rule 5250(c)(2).

The Notice stated that no later than December 2, 2013, the Company is required to submit a plan to regain compliance with the Listing Rules.  If Nasdaq accepts the Company’s plan, Nasdaq may grant the Company an extension of up to 180 calendar days from the date of the Notice, or until March 31, 2014, to evidence compliance with the Listing Rules.  The Company intends to file the Form 6-K before December 2, 2013 and therefore the Company would regain compliance immediately at that time.
