|Item 1.01 | Entry Into a Material Definitive Agreement.
|--------- | -------------------------------------------



On May 15, 2006, Dotronix, Inc. acquired a Stock Purchase Warrant from Grand Sierra Resort Corp., a Nevada Corporation (Grand Sierra) entitling Dotronix to purchase up to 5 million common shares of Grand Sierra at $0.40 per share until expiration of this warrant. The terms of the warrant require Dotronix to exercise and purchase 1,250,000 shares ($500,000) on or before May 26, 2006 and the remaining 3,750,000 common shares prior to the warrant expiration date of June 22, 2006. This warrant is included as an exhibit to this Form 8-K disclosure.



Grand Sierra has an agreement to purchase the Reno Hilton from Harrahs Entertainment, Inc., which purchase is anticipated to be completed in June 2006. The Reno Hilton is a hotel/casino entertainment complex in Reno, Nevada having approximately 2,000 hotel rooms and situated on approximately 145 acres. Assuming completion of the acquisition of this hotel/casino by Grand Sierra, which there is no assurance will happen, Grand Sierra intends to initiate and complete a comprehensive development plan to create one of the largest destination resort and entertainment centers in the western United States other than Las Vegas. Grand Sierra has advised Dotronix that it intends to revitalize and rebrand this hotel/casino complex into Grand Sierra Resort & Casino, including renovation of hotel rooms and common areas, converting a substantial portion of the hotel room areas, condominiums, development
of high class restaurants and retail shops, celebrity entertainment venues, and development of a premier large indoor water park and related facilities.
