Costs and Expenses:

    consultant costs of $1.1 million and $7.9 million, respectively.
--  Total operating expenses decreased to $4.9 million from $12.6 million,
    or a decrease of $7.7 million, primarily due to the reduction in accrual

--  The net loss for fiscal 2008 decreased by $6,501,935 from a year

    Amortization and Other Income/Expenses.
    

Key 2008 achievements include:

--  Four consecutive quarters of increased revenues, averaging 35% growth,
    quarter-over-quarter.
--  Expansion of diversified product lines including SigNature® DNA,
    BioMaterial™ Genotyping and BioActive™ Ingredients to enhance the
    Company's ability to capture a dominant position in the DNA authentication
    market.
--  Expansion of SigNature DNA markers in Cash-In-Transit industry with
    newly developed, forensically formulated products like AzSure™ Security
    Ink.
--  Training of UK police and other law enforcement teams on the detection
    and authentication of SigNature DNA markers in stolen cash.
--  Continued repeat orders of BioActive Ingredients that are being used
    by leading global brands in personal care.
--  Auditable process and controls throughout the company to support
    authentication.
--  Expanded patent and trademark portfolios which will form the basis for
    added value through future licensing revenue opportunities.
    

The Company has made significant inroads with its central SigNature DNA platform that uses botanically derived genomic DNA to mark and authenticate a range of security inks, packaging labels, and event tickets. This year, APDN has been able to develop more market-ready products, enabling faster price quotations and more concise product cycles which will provide a foundation for continued growth in 2009.

"Despite the challenges of today's economy, APDN continued to expand and grow in fiscal 2008. Our strategy remains focused on long-term sustainable growth and although the economic realities may impact us slightly in the short term, our long-term goals remain intact," stated Kurt Jensen, Chief Financial Officer.

APDN in Textiles:

One of the key highlights of the year for APDN was our launch into the world of textiles. In addition to marking fabrics with our SigNature DNA, we authenticate natural fibers by genotyping, analyzing the unique DNA content found naturally in these goods. Our newly launched services for textiles include:

--  Cotton authentication by FiberTyping™ and PimaTyping™. With
    FiberTyping, retailers or brand owners can verify that the garment that is
    labeled as Pima cotton does, in fact, contain Pima cotton. This test can be
    used to establish cotton provenance throughout the logistic chain and can
    be effectively used in commerce to ensure both fabric quality and brand
    integrity. Management believes this assay will have utility for governments
    wishing to enforce cotton trade agreements.
--  SigNature DNA marks to authenticate textiles at all points of the
    logistic chain. We expanded our collaborations to include Yorkshire
    Forward, the Textile Centre of Excellence and its consortium of companies
    throughout the Yorkshire region in the UK.
    

Dr. Benjamin Liang, Chief Technology Officer, commented, "Our FiberTyping test, which was developed to help the cotton industry, is ready for commercial use. We believe that the experience we bring to cotton will also be of great value to the wool industry. We are looking forward to our business collaborations with Supima and the Yorkshire companies in marking and authenticating textile and apparel in the new year."

"We are grateful for the strong support of our customers, strategic partners, employees and investors this year. We have made significant progress toward our goals and we believe our vision and strategy will take us there," continued Dr. Hayward.
