SAN DIEGO--Tri-National Development Corp. (OTC Bulletin Board: TNAV) has unveiled its new updated web site, www.tri-national.com. The site provides visitors with an overview of the Company's operations, management and history, and allows them direct access to Company stock quotes, financial information, press releases, SEC filings, and other stock information. The site also provides detailed descriptions and photos of the Company's growing number of projects in Arizona, California and Northern Baja, Mexico.

Michael Sunstein, President and Chief Executive Officer, said, "This new web site showcases Tri-National's assets, value and growth potential to present and future shareholders and to the investment community at large virtually anywhere in the world. As the Company's development projects move into the selling phase, we will continue to enhance the web site to incorporate the latest interactive, 3-D and virtual reality technologies in support of our sales efforts. We anticipate that the web and these multimedia technologies will dramatically increase our exposure and effectiveness in selling the Company's condos, timeshares, single family homes and residential lots, as well significantly reducing our overall sales and marketing costs."
