Marriott International Deploys LetterMark® Email
Worldwide Operator and Franchiser of Hotels Uses LetterMark™ Email to Enhance Sales and Marketing Efforts

CARY, N.C. (June 21, 2005) - Research Triangle Software, a leading developer of secure and branded electronic commerce solutions, announced today that Marriott International (NYSE:MAR) is deploying LetterMark Email in offices and hotels throughout the United States. Marriott has made LetterMark Email available to its sales and event management associates with the Midwest and Southeast regions being the first to roll-out the product. Marriott is a worldwide hospitality leader with approximately 128,000 associates and more than 2,800 properties.

LetterMark Web-Enhanced Email converts traditional one-to-one plain text email into a powerful marketing, sales and business development tool. It drives Web traffic, strengthens brand awareness and increases the retention of customer contact information by leveraging emails employees send everyday. Marriott selected LetterMark Email because it offers significantly more capability than competing products, including dynamic republishing, downloadable contact information, deep linking into Marriott's corporate Website, tracking, reporting and an easy-to-use Web-based administration system.

LetterMark Web-Enhanced Email was introduced to Marriott International by the UPTONGROUP, a brand-strategy and communications management consulting firm headquartered in Richmond, VA.

"LetterMark Email supports Marriott's marketing initiatives by enabling all of our employees to strengthen our brand with every email they send," said Kirby Smith, Vice President Field Marketing with Marriott. "With LetterMark Email, we can use multiple LetterMark templates to professionally feature specific hotel brands, promote events, announce special offers and showcase recent news."

Marriott International has over 2,800 lodging properties in the United States and 69 other countries and territories. The company is headquartered in Washington, D.C. and reported sales of $9 billion in 2003. Marriott aggressively markets its numerous hotel, conference center, executive apartment and vacation ownership resort brands under the Marriott name. These brands include: Marriott, JW Marriott, The RitzCarlton, Renaissance, Residence Inn, Courtyard, TownePlace Suites, Fairfield Inn, SpringHill Suites, Ramada International and Bulgari.
