Applied DNA Sciences Expands Executive Sales Team

STONY BROOK, NY--(Marketwire - October 13, 2009) - Applied DNA Sciences, Inc. (OTCBB: APDN), a provider of DNA-based security solutions, announced that it has expanded its sales force to include a number of veteran industry and government consultants who will be responsible for driving sales and strategic business initiatives throughout the U.S. and abroad. The new additions include Joseph L. Magno, an expert in government relations, Warren M. Pearlson, a veteran in pharmaceuticals, and others with expertise in cash-in-transit, wine, textiles and B2B technology commercialization.

Mr. Magno brings extensive government experience and is working with APDN to initiate strategies to effectively penetrate State and Federal Government organizations. He successfully founded and led a number of technologically-driven companies, his last being acquired and sold to General Electric in 1996. Earlier in his career, Mr. Magno held positions in sales and management in a number of large multi-national technology companies. While serving in government, he advised both the New York State Governor and Legislative Leadership on economic development, research and education. Mr. Magno has served on a number of boards including NYSTAR, University at Albany Bioscience Development Center, NYS Software Network, NYS Institute for Entrepreneurship and currently serves on the Watervliet Arsenal Partnership Board and the Albany Science and Technology Law Center Board of Advisors.

"I am delighted to spearhead a number of initiatives to help protect products within government supply and logistic chains and ultimately ensure public safety. It's reassuring to know that DNA technology is available to provide the necessary forensic checks and balances not sufficiently addressed by other security measures," commented Mr. Magno.

Mr. Pearlson is a 25-year veteran in the pharmaceutical industry including positions of increasing responsibility at Astra Pharmaceuticals, Warner Lambert/Parke-Davis and most recently with Pfizer. His extensive industry network of contacts and strategic management skills will establish the client base most positively impacted by DNA technology.

"Companies have the ability and the obligation to put systems in place to protect the public. Not only do counterfeit drugs defraud consumers, they can cause great harm and even fatalities. DNA provides a forensic level of confidence which is why it is so appealing to providers and consumers," stated Mr. Pearlson.

Over the last year, APDN has evolved an integrated, global matrix of sales consultants and regional representatives compensated largely by sales commissions. In addition to four newly appointed sales consultants, the company recently began collaborating with a British Wine Master to help us sell our authentication technologies in Bordeaux and throughout Europe.

"We have demonstrated our ability to execute and provide first-category services across multiple sectors," said Dr. James Hayward, CEO of APDN. "With the expansion of our sales force, we expect our sales cycle to shorten and our penetration within sectors to increase."
