Horizon Technology Announces
Pacific Oil & Grease Disk Exchange

Salem, NH, June 23, 2008 — Horizon Technology's mission is to help analytical labs meet their business objectives, including lowering operating costs, decreasing sample turnaround times, and improving the quality and consistency of results. This mission embraces the provision of a product line that ensures top performance of Horizon Technology equipment.

The absolute commitment to providing a total solution, with products that meet SPE needs, results in a recommendation of the use of the Horizon Technology complete line of supplies, including a number of select major brands. SPE Disks that Horizon Technology supplies and supports include:

• Horizon Technology, Pacific O&G SPE Disks *
• Horizon Technology, Pacific Fast-Flow Pre Filters *
• Horizon Technology, Atlantic SPE Disks *
• J.T. Baker Speedisk
• 3M Empore
• Whatman

SPE disks and supplies purchased from a vendor or distributor other than Horizon Technology, cannot be guaranteed by Horizon Technology, in regards to the quality, accuracy or performance, and therefore Horizon Technology is unable to provide technical support for these products.

In Horizon Technology's continued commitment to providing a total SPE solution, with high quality, supported products that meet all SPE needs, the following deal was announced. Send all your non-supported oil & grease SPE disks to our head office in Salem, NH, and Horizon Technology will exchange them, one-for-one, with 'Certified for Automation' Horizon Technology, Pacific SPE Disks. Horizon Technology laboratory tests and certifies all Pacific disks and pre filters, ensuring compatibility with our automated products, and guaranteeing high quality results. And there's more! The receipt of an invoice outlining what is currently paid oil & grease disks will be matched.
