CombiMatrix and Pathology, Inc. Form Partnership to Market and Distribute
Prenatal Tests

Pathology, Inc. Will Market Chromosomal Microarray for Products of Conception
Testing Market in Nevada, California, Key Midwest Metropolitan Areas

IRVINE, Calif., Nov. 6, 2012 (GLOBE NEWSWIRE) -- CombiMatrix Corporation
(Nasdaq:CBMX), a molecular diagnostics company performing DNA-based testing
services for cancer and developmental disorders, today announced that it has
entered into a strategic partnership with Pathology, Inc. whereby Pathology,
Inc. will market and distribute CombiMatrix chromosomal microarray tests for
the Products of Conception (POC) testing market in designated geographic
areas. The POC testing market is a subset of the overall prenatal testing

The two-year agreement gives Pathology, Inc. the exclusive right to market or
distribute the microarray tests on behalf of CombiMatrix in the states of
California and Nevada and the St. Louis and Chicago metropolitan areas.
Pathology, Inc. is a full-service, independent Women's Health laboratory based
in Torrance, California.

POC testing allows OB/GYN physicians and other women's health clinicians to
better determine if there is a genetic cause behind a miscarriage or multiple
events. As in other areas of prenatal genetic analysis, microarray testing is
believed by many to be the coming standard of care as it identifies a greater
number of possible genetic abnormalities more accurately than traditional

"This agreement allows us to better serve the POC market, a very important
area of specialty for our physician customers and their patients," said Vicki
DiFrancesco, President and CEO of Pathology, Inc. "Our commercial team, along
with operational and analytical support of CombiMatrix, will result in
broadening the use and acceptance of chromosomal microarray testing as a
better solution. We believe this partnership will prove to be a beneficial
expansion of services and customer access for both of our companies."

CombiMatrix President and CEO R. Judd Jessup noted that the agreement with
Pathology, Inc. enables CombiMatrix to broaden its geographic reach and expand
its access to the Women's Health market.

"Working closely with Pathology, Inc. allows us to immediately expand our
marketing efforts in the prenatal market for POC testing throughout important
areas like California and Nevada and densely populated metropolitan areas like
St. Louis and Chicago," Jessup said. "Furthermore, this will improve our speed
of access to Pathology, Inc.'s established customer base of OB/GYNs. Finally,
we believe this agreement offers CombiMatrix and Pathology, Inc. the
opportunity to educate the pathologists in their network about the advantages
of using the POC test compared to the historic, traditional standard of
karyotyping in the prenatal market."

The agreement calls for both companies to participate in sales force training
and market development activities and indicates that Pathology, Inc. will
generate a minimum amount of tests each quarter in order to maintain the
exclusive arrangement.
