Align Technology Files Counter-Claim Against Discus Dental

Company Seeks Minimum of $40 Million in Damages from Discus

Santa Clara, Calif., June 17, 2002 - Align Technology, Inc. (Nasdaq: ALGN), the inventor of Invisalign®, an orthodontic appliance used to straighten teeth without wires and brackets, today filed a $40 million counter-claim against Discus Dental with the American Arbitration Association. Discus is a provider of aesthetic and clinical dental products with whom Align had an exclusive Invisalign marketing agreement until April 2002. Align seeks damages in the counter-claim arising from Discus' misrepresentation of its capabilities, improper marketing of Invisalign to general dentists, breach of duties regarding confidentiality, and unfair and fraudulent business practices.

In April 2002 Align exercised its contractual right to terminate its exclusive marketing agreement with Discus, who later filed for arbitration against Align with the American Arbitration Association.

About Align Technology, Inc.

Align Technology designs, manufactures and markets Invisalign, a proprietary method for treating malocclusion, or the misalignment of teeth. Invisalign corrects malocclusion using a series of clear, comfortable and removable appliances that gently move teeth to a desired final position. Because it does not rely on the use of metal or ceramic brackets and wires, Invisalign significantly reduces aesthetic and other limitations associated with braces. Invisalign is appropriate for treating adults and older teens. Align Technology was founded in March 1997 and received FDA clearance to market Invisalign in 1998.
