Santa Clara, Calif. - December 20, 2001 -- Align Technology, Inc. (Nasdaq: ALGN), manufacturers of the Invisalign^® System, a proprietary method of straightening teeth without unsightly wires and brackets, announced today an agreement with HealthCapital Financial Group, LLC to provide low-cost financing for consumers who use their revolutionary Invisalign^® System.

In an effort to provide prospective Invisalign patients with convenient payment options for treatment, this arrangement will allow dental professionals to offer Invisalign to patients for as little as $129/month. It is intended to help patients take the financial burden out of dental health, and provides certified doctors with a valuable sales tool for discussing Invisalign with their patients.

"We are pleased to be partnering with HealthCapital Financial Group, a leader in elective medical procedure financing for over four years and to be able to make Invisalign^® more affordable for patients without adding unnecessary extra cost to doctors," said Zia Chishti, chief executive officer of Align Technology.

Jonathan Preiser, managing partner for HealthCapital, stated, "HealthCapital's PatientFinance.com is thrilled to work with Align Technology as they roll out the Invisalign System to certified doctors nationwide. Our patient finance program offers dental professionals and their patients alternative financing that is useful in a good economy and required in a weakening one."

About Align Technology

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 mental 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.
