FORT WORTH, Texas--(BUSINESS WIRE)--Dec. 3, 2001

(OTCBB:TEXN) 21st Century Technologies, Inc. is pleased to announce the election of Richard H. Grob to the Board of Directors.

Along with the Board position, Mr. Grob has also been hired as Vice President of Sales and Marketing for Trident Technologies, Inc. Scott Sheppard, Chief Operating Officer for 21st Century Technologies, Inc. commented on Mr. Grob's acceptance of the positions with Trident and 21st by stating, "I welcome an individual of the caliber of Mr. Grob to the management team of Trident Technologies. His business background, especially his experience in sales management, will be a great asset for the team. Mr. Grob and Mr. Mydlach have know each other for a number of years and bring a synergy of experience and energy that should benefit all 21st Century stockholders."

Richard Grob, a resident of Las Vegas, brings 25 years of business experience. Mr. Grob spent over 10 years with Honeywell beginning as a sales representative for their Energy Management Division in Southern California. After 3 years, he was promoted to sales manager. While sales manager, his division was No.1 in sales for the country two years straight. As sales manager he developed the first co-generation plant in Southern California to operate on methane gas from a landfill, selling it to a Community College. He also developed a special environmental package for use by the United States Air Force at Vandenburg Air Force Base, securing secret satellites awaiting launch. Both projects provide an example of Mr. Grob's attitude regarding sales, "Listen to the customer, give him what he needs, not necessarily what he wants. Because sometimes the customer doesn't know what he really needs and you have to tell him."

After being promoted to a Branch Manager, he increased profits in the first year 115% by detail participative management and growth was 223% of plan by targeting sales properly. His branch developed several new product offerings that were adopted nationwide by Honeywell. While Branch Manager, Mr. Grob was responsible for additional product line including fire/life safety and environmental quality products. Responsibilities included all facets of the operation; sales, installation, personnel and budget management with supervision of over 100 employees. After 1 year as Branch Manager in Orange County, California, Honeywell transferred him to open a new branch in the Inland Empire area of California. One year later, after successful operations exceeding plan in both profit and sales, Honeywell transferred him to Las Vegas to assume responsibility for a new branch combining both service and systems/construction. In this position he was responsible for sales, service, installation/construction of energy management offerings, fire/life safety products and environmental control offerings. A few of the projects Mr. Grob worked on included: The Flamingo Hotel and Casino, Caesar's Palace Hotel and Casino, McCarran International Airport, Clark County School District and Clark County Library. He also worked with the government and DOE at the Nevada Nuclear Test Site providing specialized equipment to meet their needs. In addition to Honeywell, Mr. Grob's experience also includes tenures with Sylvania Lighting (subsequently bought by Siemens) and Director of Security for Elvis Presley Enterprises, Inc.

In addition to owning a mortgage company for six years, for the past 10 years, Mr. Grob has served as a consultant in the fire/life safety, environmental quality and security industries. Clients have included a Japanese auto plant, numerous commercial real estate developers and several construction companies that were bidding large projects.

Mr. Grob has also been active in community events and has helped establish several charities to benefit children. Additionally, he worked closely with the Make-A-Wish Foundation and Special Olympics.

Richard Grob commenting on the new positions said, "...responding to an inquiry by a potential customer, that customer is expressing a need. As time progresses, the need, or perceived need, lessens. It is vital to get to the customer as soon as possible with follow-up. Given the industry in which we exist, when an incident can bring a need to the forefront almost instantly, then immediate closure is vital. I am highly impressed with the product and look forward to spreading the good word.

"My past success has been predicated on making the customer part of the team. We need to talk with the customer, find out his true needs and, in some cases, develop a product that meets those requirements. People are not going to come pounding on our door---yet! We have to go to them until the word gets out that we have the best mousetrap in town. While all sales are important, a good sales structure includes all types of sales. It is important to shoot rabbits while you are hunting bear. The little sales keep you alive while the big one is coming."

Jim Mydlach, newly appointed President of Trident Technologies, Inc. referred to Mr. Grob by saying, "Dick and I have known each other for almost 30 years. Our backgrounds could not compliment each other better and (our) past experience of working together in management capacities on projects have all ended in success. I look forward to success--again."
