Quality Systems, Inc. and National Electronic Attachment, Inc. Announce an Agreement
TUSTIN, Calif. and ATLANTA — Jan. 23, 2001 — Quality Systems, Inc. (Nasdaq:QSII) of Tustin and National Electronic Attachment, Inc. (NEA) of Atlanta announced today that they have entered into an agreement to offer NEA's FastAttach(TM) electronic insurance claim attachment system to QSI's clients.

As a result of this partnership, QSI client dental offices will be able to transmit attachments (x-rays, perio charts, intra-oral pictures, narratives and EOB's) electronically for quicker, more efficient review by Insurance Payors. A further extension to QSI's e-business suite, this is a significant benefit for dental offices as claim processing is accelerated, and the need to duplicate film and mail attachments is eliminated.

The QSI Dental System offers a range of systems and services to cost-effectively meet the needs of any size practice. The Company's Clinical Product Suite features integrated restorative and perio-charting, intra-oral images, and digitized x-rays to allow for seamless movement of data throughout the system.

NEA offers systems designed to facilitate the process of insurance submissions and processing by allowing required claim attachments to be electronically transmitted. Visit www.Fast-Attach.com for additional information.
