Align Technology Announces Supplementary Plan For Its Pakistani Operations

Operating Efficiencies Allow Company to Trim Staff

Santa Clara, Calif. - November 14, 2001 -- Align Technology, Inc. (Nasdaq: ALGN) the inventor of the Invisalign^® System, a proprietary method of straightening teeth without unsightly wires and brackets, announced today in a conference call two initiatives which further support the company's core strategies.

As a precautionary measure to ensure uninterrupted business given the current political climate, the company has initiated the backbone of a supplemental plan for its Pakistani facility in two separate locations. A new operation to perform computer tooth modeling work now done in Pakistan is being developed in Dubai, one of the United Arab Emirates. The new facility is expected to be operational by the end of the quarter. The second site, located in Costa Rica, is expected to be operational during the first quarter of next year.

In addition, Align announced today that largely as a result of continued improvements in its manufacturing efficiencies and its goal to bring manufacturing overcapacity down to the 15 to 25 percent level, the company decreased its workforce by approximately 50 people, or less than five percent of its worldwide employee base. The company believes this action will realign its business model to be consistent with current business conditions. In addition, the reduced overcapacity will contribute to improved margins over time. Align remains confident that it is prepared to accommodate any potential spikes in product demand.

"The actions being announced today reinforce our strategy to narrow the gap between capacity and demand, and enhance our ability to continue to meet the needs of our customers," said Zia Chishti, Chief Executive Officer of Align.

About Align Technology, Inc.

Align Technology designs, manufactures and markets the Invisalign System, a proprietary new method for treating malocclusion, or the misalignment of teeth. The Invisalign System corrects malocclusion using a series of clear, nearly invisible, 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, the Invisalign System significantly reduces the 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 the Invisalign System in 1998.
