Champion Thread, Applied DNA Sciences Enter Anti-Counterfeiting Agreement

Champion Thread Co. (CTC), an industrial sewing thread supplier based in Gastonia, N.C., has
entered into an agreement with Story Brook, N.Y.-based Applied DNA Sciences Inc. (APDN) a DNA-based
security solutions provider whereby CTC will become the exclusive reseller of APDNs SigNature DNA
Markers in CTC’s global markets. The companies will work together to develop, market and distribute
Signature DNA-marked products to the textile industry.

Signature DNA technology involves using DNA segments from botanical sources, rearranging them
into unique encrypted sequences and then implementing one or more layers of anti-counterfeiting
techniques. Signature DNA marker detection devices and polymerase chain reaction kits enable
customers to quickly complete on-site verification of branded textile products.


Champion Thread will exclusively resell Applied DNA
Sciences SigNature™ DNA markers in the company’s global markets.

Signature DNA thread will aid retailers, accessory and clothing manufacturers and governments
authenticate thread, yarn and fabric at any stage in the supply chain, according to APDN. The
effectiveness of the markers in authenticating sewing thread has been independently verified by
Idaho National Laboratories.

“With this OEM relationship in place, we are now better able to service the
anti-counterfeiting needs of textile and luxury brand owners,” said James A. Hayward, Ph.D., CEO,
APDN. “This is one more indication of the many ways in which Signature DNA can be utilized to
