           EPOCH BIOSCIENCES ANNOUNCES THIRD QUARTER FINANCIAL RESULTS

        BOTHELL, WA, NOVEMBER 4, 2003 -- Epoch Biosciences, Inc. (Nasdaq: EBIO),
a provider of proprietary products that accelerate genomic analysis, today
reported revenues for the third quarter of $2.0 million compared to $2.7 million
in the like period in 2002, which included $686,000 of revenue from the San
Diego-based oligonucleotide business that was sold in May 2003. Excluding those
revenues, total revenues increased 2% from the third quarter of 2002. The net
loss during the current quarter was $332,000, or $0.01 per share, compared with
a net loss of $861,000, or $0.03 per share, in the third quarter of 2002.

William G. Gerber, M.D., chief executive officer, said, "We continued to make
progress on our financial goals during the quarter, while achieving important
strategic milestones that open new markets to us. During the quarter, we
recognized increased revenues from direct sales of Assay Validated Probes, MGB
Eclipse(TM) assays that we design, manufacture and validate for customers to
targets that they specify, with performance guaranteed by Epoch. We announced a
supply agreement with our first key corporate account, Millennium
Pharmaceuticals, and other prospective accounts are in the late stages of
evaluating the product."

"We believe that the Assay Validated Probe business and QIAGEN's launch of the
QuantiTect(TM) Custom Gene Expression Assays incorporating our MGB Eclipse
technology this quarter are part of a trend in the research reagents business
towards meeting the needs of the performance-driven customer."

"This also was the quarter where our robust technology took us into markets
beyond the research sector," Gerber said. "Through licensing agreements, Epoch
expanded its reach into the environmental testing and food safety markets. We
made initial shipments to Applied Biosystems of our Eclipse Dark Quencher
product for use in microbial detection in the environmental testing field. We
signed a license and supply agreement with BioControl for incorporation of our
MGB Eclipse Probe System technology in their food testing products. We also made
progress in developing reagents as part of our initial entry into the
diagnostics business."

"The new markets and resulting new revenue streams realized this quarter
complement our established businesses and move us closer to profitability."

THIRD QUARTER FINANCIAL PERFORMANCE:

Total revenues for the quarter ended September 30, 2003 decreased 24% compared
to the third quarter of 2002 to $2,010,000. Excluding revenues from the San
Diego-based oligonucleotide business the Company sold in May 2003 from the prior
year's quarter, total revenues increased 2% from the third quarter of 2002.
Product sales decreased from $2.0 million to $690,000 due to a $686,000 decline
in oligonucleotide revenues from the San Diego operations, a decrease in initial
MGB Eclipse catalog orders from Amersham Biosciences recognized in 2002, and the


                                       1


reclassification of product revenues as royalties, offset by higher sales of MGB
Eclipse Probe Systems to end users. License fees and royalties increased to $1.2
million from $277,000 a year ago due to payment of higher minimum royalties from
Applied Biosystems and Third Wave Technologies. Contract research revenues
decreased to $101,000 from $407,000 last year due to termination of contracts in
place a year ago.

Total operating expenses for the third quarter were $2.3 million. Cost of
product sales decreased to $463,000 from $1.1 million in the third quarter of
2002 due to decreased product sales and elimination of San Diego's manufacturing
costs. Research and development expenses decreased to $952,000 from $1,051,000
in the comparable quarter of 2002 due primarily to lower personnel costs and
higher allocations to cost of goods sold. Selling, general, and administrative
expenses decreased to $932,000 from $1.4 million in last year's third quarter
due to reduced sales and product marketing expenses and the absence of costs
from the San Diego operation.

For the nine months ended September 30, 2003, Epoch reported revenues of $6.9
million compared to $7.4 million in the first three quarters of 2002. Excluding
revenues from the divested oligonucleotide business in both nine-month periods,
total revenues increased 13% from $5.7 million in 2002 to $6.4 million in 2003.
The net loss for the first nine months of 2003 was $4.3 million, or $0.16 per
share, compared to $3.3 million, or $0.13 per share, for the same period in
2002. Excluding the loss on the sale of San Diego operations of $2.8 million
recognized in the second quarter of 2003, the net loss was $1.5 million, or
$0.05 per share, for the nine months ended September 30, 2003.

As previously announced, Epoch sold the assets and customer base of its non-core
oligonucleotide operations located in San Diego, California to Eurogentec in a
transaction that closed in May 2003 in order to focus on its proprietary
products and preparations to enter the diagnostics business.

At September 30, 2003, the Company had unrestricted cash and cash equivalents of
$4.6 million. Based on results of operations and cash flows during the current
quarter, we anticipate that existing cash balances, projected cash from
operations and unused borrowing capacity under existing bank loans will be
sufficient to meet our anticipated working capital and capital expenditure needs
into at least 2005.

THIRD QUARTER AND EARLY FOURTH QUARTER HIGHLIGHTS:

o  Epoch established a significant supply agreement with Millennium
   Pharmaceuticals, Inc. to provide multiplexed MGB Eclipse assays to gene
   targets specified by Millennium. This was the first key account announcement
   under Epoch's Assay Validated Probe program, an initiative that offers custom
   assays for customer-defined targets with guaranteed assay performance
   following functional testing at Epoch. During the third quarter, Epoch also
   delivered trial orders to several other prospective key accounts in the
   pharmaceutical and biotechnology industries. Assay Validated Probes are sold
   directly to large customers by Epoch professionals.

o  The Company's partner, QIAGEN N.V. (Nasdaq:QGENF) launched the QuantiTect
   Custom Gene Expression Assays, probe and primer sets for quantitative
   real-time PCR based on MGB Eclipse technology. The assays enable customers to
   design and order assays to measure the


                                       2


   expression of any gene from any organism in minutes using software developed
   by Epoch. QIAGEN launched the catalog version of the product in the previous
   quarter.

o  Epoch granted a global, non-exclusive license to BioControl Systems, Inc., a
   food testing company, to incorporate MGB Eclipse Probe System technology into
   BioControl's detection products for specified food contamination testing
   systems in return for technology fees and royalties. The agreement
   represented Epoch's first participation in the food testing business.

o  Epoch granted a global, non-exclusive license to Applied Biosystems Group
   (NYSE:ABI) for Eclipse Dark Quencher technology. Epoch will supply the
   quencher for incorporation into Taqman(R) probes for use in 5' nuclease
   assays. The agreement covers use of quencher technology for detection of
   microorganisms in the environment, and expands Epoch's reach into the
   environmental testing market.

o  Epoch terminated a 2002 distribution and licensing agreement with Amersham
   Biosciences, the life sciences unit of Amersham plc (NYSE:AHM), for the
   co-exclusive marketing of MGB Eclipse Probe Systems. Epoch is in discussions
   with other prospective distributors.

o  Company researchers completed the development and listing with the FDA of
   the sixteenth of a targeted twenty Analyte Specific Reagents (ASRs). ASRs are
   test components used by clinical laboratories in diagnosing infectious
   diseases, cancer, genetic diseases, and various other conditions.

o  The Company, one of two finalists for Block 1 of the Joint Biological Agent
   Identification and Diagnostic Systems (JBAIDS) Program of the department of
   Defense, was notified it had not been awarded the contract.

o  The Company renewed a financing arrangement with Silicon Valley Bank. The
   equipment lending facility provides up to $1.0 million in financing through
   June 2004.
