   Align Technology Announces Changes to Research & Development Department

    SANTA CLARA, Calif., Nov. 10 /PRNewswire-FirstCall/ -- Align Technology,
Inc. (Nasdaq: ALGN), the inventor of Invisalign(R), a proprietary method of
straightening teeth without wires and brackets, announced that Amir Abolfathi,
Vice President of Research & Development has resigned from Align to start his
own company. Mr. Abolfathi will continue to serve as a consultant and assist
in the search for a replacement.
    "Amir has made key contributions to the R&D effort at Align," stated
Thomas M. Prescott, President and CEO of Align Technology, Inc. "His
leadership and innovation over the last five years has helped Align become a
leader in the field of orthodontic techniques. We wish Amir well and thank him
for his many contributions."
    "I believe that Align Technology is well positioned to become a leader in
the treatment of malocclusion," said Abolfathi. "I wish the Company success
and look forward to following their progress going forward."

    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, 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,
Invisalign 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 Invisalign in 1998.
    To learn more about Invisalign or to find a certified Invisalign doctor in
your area, please visit www.invisalign.com or call 1-800-INVISIBLE.

    This news release states that Align is well positioned to become a leader
in the treatment of malocclusion, which is a forward-looking statement. This
statement relates to expectations about future events or results and is based
upon information available to Align as of the date hereof. Readers are
cautioned that forward-looking statements are only predictions and are subject
to risks, uncertainties and assumptions that are difficult to predict. As a
result, actual results may differ materially and adversely from those
expressed in any forward-looking statement. Factors that might cause such a
difference include, but are not limited to, risks relating to Align's ability
to manage growth, the loss of key personnel or the inability to attract and
retain key personnel, Align's limited operating history, customer demand for
Invisalign, acceptance of Invisalign by consumers and dental professionals,
competition from manufacturers of traditional braces, Align's ability to
protect its intellectual property rights and potential intellectual property
or product liability claims or litigation. These and other risks are detailed
from time to time in Align's periodic reports filed with the Securities and
Exchange Commission, including, but not limited to, its annual and quarterly
reports. Align undertakes no obligation to revise or update publicly any
