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

On June 3, 2006 IWT Tesoro Corporation received an OTC Delinquency Notification from the NASD with respect to its shares of common stock that are quoted on the OTC Bulletin Board under the symbol IWTT.OB. The Notification Date on the Notice is May 30, 2006. At that time, the OTC Bulletin Board added an “E” to the end of the ticker symbol for Tesoro. An “E” is automatically added to the ticker symbol of any company that has failed to make its required periodic reports with the SEC.

The Company has been unable to file its 10-Q for the quarter ended March 31, 2006. Accordingly, unless the Company files its Form 10-Q on or prior to June 26, 2006 or is able to successfully appeal or stay any proposed delisting, the Company’s common stock will be subject to delisting from the OTC Bulletin Board beginning May 22, 2006. There can be no assurance that the Company will be able to file its quarterly report on Form 10-Q by June 26, 2006.
