SANTA CLARA, Calif., Sept 28, 2006 /PRNewswire-FirstCall via COMTEX News Network/ -- Align Technology, Inc. (Nasdaq: ALGN), the inventor of Invisalign(R), a proprietary method of straightening teeth without wires or brackets, announced today that it has signed a Binding Settlement Term Sheet with OrthoClear, Inc., OrthoClear Holdings, Inc., and OrthoClear Pakistan Pvt. Ltd. ("OrthoClear") to end all pending litigation between the parties and execute a formal settlement agreement within fifteen days. Effective immediately, OrthoClear will no longer accept new patient cases for treatment. Upon the earlier of the Closing of the formal settlement agreement or October 12, 2006, OrthoClear will consent to the entry of an Exclusion Order by the International Trade Commission (ITC), prohibiting importation of OrthoClear aligners into the United States, and will assign and transfer to Align all intellectual property rights with application to the correction of malocclusion.

    The Binding Settlement Term Sheet includes the following terms:

    -- Effective immediately, OrthoClear will stop accepting new patient cases
       for treatment;
    -- OrthoClear will consent to the entry of an exclusion order by the
       United States International Trade Commission (ITC), enforced by the
       United States Customs Service, which prevents OrthoClear from importing
       its dental aligner products into the U.S., either directly or through a
       third party;
    -- OrthoClear and Zia Chishti, its CEO, and Charlie Wen, its President,
       will transfer and assign to Align all intellectual property rights with
       application to the treatment of malocclusion;
    -- OrthoClear principals Zia Chishti, Charlie Wen, Peter Riepenhausen, and
       Christopher Kawaja will sign 5-year, global non-compete agreements in
       the field of removable aligner therapy products and related software
       market;
    -- OrthoClear employees Joe Breeland and Jeff Tunnell will sign 5-year
       U.S. non-compete agreements prohibiting their personal participation in
       the removable aligner therapy product and related software market;
    -- Align will make Invisalign treatment available to OrthoClear patients
       in the United States, Canada and Hong Kong at no charge from Align;
    -- The Parties will dismiss all pending litigation against each other and
       release all related claims;
    -- Align will make a one-time cash payment of $10 million to OrthoClear
       Holdings, Inc.

"This resolution achieves all of Align's litigation objectives and allows us to fully focus the Company's energies and resources on providing innovative products and excellent service to Invisalign customers," said Thomas M. Prescott, Align President and Chief Executive Officer. "We are particularly committed to helping OrthoClear patients and their doctors minimize disruptions in their treatment by getting started with Invisalign."

Align will pay OrthoClear an additional $10 million if, at or prior to the Closing of the formal settlement agreement, OrthoClear obtains requisite approval from its shareholders to discontinue all design, manufacture, marketing and sales of removable dental aligners worldwide. If at the Closing OrthoClear does not have the requisite shareholder approval, Align will place $10 million in escrow for a period of 30 days. If OrthoClear obtains and certifies the requisite shareholder approval on or prior to the 30th day, the escrowed amount plus accrued interest will be released to OrthoClear. If OrthoClear does not certify that it has shareholder approval by the 30th day, all escrowed funds will be returned to Align and Align shall have no further payment obligation.

The Binding Settlement Term Sheet is the result of a settlement conference mandated and supervised by an administrative law judge as part of pre-trial proceedings in the ITC action against OrthoClear. There has been no finding of wrongdoing by any Party or by Joe Breeland, Zia Chishti, Christopher Kawaja, Ross Miller, Peter Riepenhausen, Jeff Tunnell or Charlie Wen.

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.
