Trestle's Xcellerator Services Offering Selected by Harvard Medical School Continuing Medical Education for Dermatopathology Update Course

Course Attendees and Pathologists From All Over the World to Benefit From Pre-Event Examination of Digital Pathology Slides

IRVINE, CA -- (MARKET WIRE) -- June 30, 2005 -- Trestle Holdings Inc. (OTC BB: TLHO), a supplier of digital imaging systems and services for pathology, drug safety and discovery, today announced that its Xcellerator services offering has been selected for use at an upcoming Harvard Medical School Continuing Medical Education course. The event, "Dermatopathology Update with Mini-symposium on Mucosal Pathology and 'Hands on' Slide Seminar on Adnexal Tumors," will be attended by practicing pathologists, dermatopathologists and dermatologists from all over the world. It is to be held September 15-17, 2005, at the Fairmont Copley Plaza Hotel, Boston, MA. See:

Course organizers expect Trestle's web-based services to make it possible for onsite course attendees -- and even those who cannot attend the course in person -- to preview interesting pathology cases, originating from various countries, via the internet. The course faculty has selected each case.

Trestle's Xcellerator services offering complements the company's workflow software applications to provide a managed, online data-mining and virtual microscopy slide image acquisition and viewing service designed for pathology laboratories. It is targeted at pharmaceutical, biotechnology and healthcare organizations, as well as for use in research settings, and medical and veterinary schools. Xcellerator workflow software applications work in conjunction with Trestle's managed services to address a key challenge associated with hosting seminars of this type, and with pathology education in general: the risk and cost associated with providing physical access to glass slides of rare or irreplaceable tissue. Unlike high-resolution digital images, glass slides can easily be damaged during handling or transport, and can be viewed by only one person at the same time.

"Trestle's digital slide system will provide our students with unlimited time to preview dozens of high-resolution slides before the event has even begun -- from their office or home. This technology allows pathologists scattered all over the world to compare their diagnoses with those of world experts with just a few clicks," said Artur Zembowicz, M.D., Ph.D., a dermatopathologist at the Massachusetts General Hospital and assistant professor of pathology at the Harvard Medical School.

Xcellerator workflow applications and services are designed to address the efforts of clinical laboratories and drug-development organizations to reduce the time and cost associated with processing and analyzing tissue slides, normally viewed under a standard microscope. Additionally, the proprietary data-mining functions offered by the system's digital archival functions can enable workflow enhancements such as rapid side-by-side comparisons, access to digital archives, and support for computer-assisted analysis.

"We are seeing adoption of our remote microscopy systems across many healthcare, research and teaching establishments. It is very encouraging that a prestigious school such as the Harvard Medical School is taking advantage of the efficiencies offered by our service bureau," said Maurizio Vecchione, CEO of Trestle Holdings Inc. "Collaboration and peer review are key aspects of international seminars, and we expect the Trestle system to facilitate improved expert review and discussion."
