Item 3.01.  Notice of Delisting or Failure to Satisfy a Continued Listing Rule
or Standard; Transfer of Listing.

(a) As previously reported, on May 16, 2007, MathStar, Inc. (the "Company") was
advised by the NASDAQ Listing Qualifications Department that The NASDAQ Stock
Market ("NASDAQ") was reviewing the Company's eligibility for continued listing
on The NASDAQ Global Market because the Company did not comply with the minimum
$10,000,000 stockholders' equity requirement for continued listing set forth in
Marketplace Rule 4450(a)(3). To facilitate the review, NASDAQ asked the Company
to provide to NASDAQ on or before May 31, 2007 a specific plan and time frame to
achieve and sustain compliance with all NASDAQ Global Market listing
requirements, including the minimum stockholders' equity standard.

On May 23, 2007, the Company submitted its plan to NASDAQ and stated that it
expected to gain compliance with the stockholders' equity requirement when it
completed its public offering of its common stock.

On June 18, 2007, the Company closed on its public offering and received net
proceeds from the sale of its shares, after the payment of underwriting
discounts and commissions and offering expenses, of approximately $32.4 million.
As a result of the closing in the Company's public offering, it now has
approximately $36.4 million in stockholders' equity based on its stockholders'
equity as of May 31, 2007. Therefore, as of the date of this Current Report on
Form 8-K, the Company believes it has regained compliance with the stockholders'
equity requirement of NASDAQ Rule 4450(a)(3).

NASDAQ will continue to monitor the Company's ongoing compliance with the
stockholders' equity requirement and, if at the time of the Company's next
periodic report the Company does not evidence compliance, it may be subject to
delisting.
