Sales decreased significantly for fiscal year 2013 compared to fiscal year 2012 primarily due to failures in production equipment, which are  now being closely monitored. Customer demand remained strong throughout the fiscal year and the order book at year-end and at present is at unprecedented levels.

The company's reputation for producing high quality, unique dextran products continues to grow throughout the world. New customer audits of the company's facilities and practices has led to a expanding client base, along with the return of customers who temporarily sourced less expensive but inconsistent dextran products from China. The company received a number of urgent requests for product and has responded to the best of its ability.

President and CEO George Usher is encouraged that the economy appears to be stabilizing, and more specifically that the global hog market appears to be rebounding, therefore increasing demand for iron dextran. "We are experiencing a dramatic increase in orders and customer audits of our facilities and manufacturing practices. These audits help assure our customers that they can rely on us for a consistent supply of the highest grade product available, reflected in the increased demand across our product portfolio, with interest in the liquid and the higher margin powdered products."

The Company shares are traded on the Over the Counter Bulletin Board (www.otcbb.com).
