KENNESAW, Ga. -- Tectonic Network(TM), Inc. (OTCBB:TNWK), formerly Return On Investment Corporation today announced that Security Door Controls (SDC) was awarded the "Product Achievement Award" at the International Security Conference for their company web-site. A total of 83 new products and services were entered into the New Products Showcase program, which was established more than a decade ago to identify and display innovation in electronic security products and services. The SDC (www.sdcsecurity.com), web-site designed and developed by Tectonic Solutions, was recognized for its many innovative functions for its users at the International Security Conference, held in Las Vegas, April 7, 2005.

Rick Geringer, Vice President of Marketing at SDC stated, "We're proud to win top honors especially in the largest security industry convention in the US. Moreover, it's rare to see an equipment manufacturer win in the business services category."

Richard Rast, Executive Vice President and General Manager of Tectonic Network added, "This is a major success for SDC and we are excited to have had the opportunity to support SDC by developing this website application. They not only have achieved an important validation from their main industry association, but to be chosen as the top performer among all the applicants is an impressive feat, and we are pleased to be a part of that accomplishment."

The web-site, designed and developed by Tectonic Network, includes an SDC access control System Design Wizard and Project Manager toolset that enable product selection, specification, system design, and creation of project folders. When products are selected and saved into Project Manager, all datasheets, installation instructions, templates and pricing are automatically saved into organized Project Folders. From Project Folders, users may generate project document packets, structured reports, RFQs and project quotations that may be saved and exchanged with SDC distributors.

Tectonic Network designs, develops and deploys internet applications that help building product manufacturers serve the right information, in the right format, in the right place, at the right time. Custom built Tectonic Network Solutions allows architects and designers, specifiers, distributors, building owners, and contractors to search for products based on attributes, application, or project-type and to save the search results for future access. These tools enable the building product manufacturer's customers to more effectively choose, configure, visualize, and incorporate product information into design documents and specifications.
