Commenting on the results, Mike Gulett, Chief Executive Officer, said:

"Traditionally, the third quarter is seasonally a quieter quarter for the
semiconductor industry and we saw a continuation of the contract deferrals which
have affected our business. Although we introduced a number of important
products later in the quarter, we expect shipments of these new products to have
greater impact in the upcoming periods.

A growing number of our customers have gone into production with
ARCtangent-based products this year and as a result, we achieved a record
royalty quarter with a 40% increase over the preceding quarter. Although
customers continue to delay new designs in North America, we have focused our
efforts on expanding business in Asia. As a result, ARC grew its Asian business
93% over the previous quarter to a record level.

We continue to focus on optimising our cost structure each quarter. This week we
implemented a further cost reduction programme to reduce operating expenses and
cash burn. We are also taking steps to restructure the business into three
Business Unit organizations, to better focus and align our resources."

Chief Executive's Review

Overview

In the first 9 months of 2003, ARC reported flat turnover at constant exchange
rates to �7.8 million, down 8% with currency impact from �8.5 million over the
same period last year. Operating expenses before exceptionals, amortisation and
depreciation were reduced by 7% to �20.7 million. Pre-exceptional net loss
increased by 1% to �15.8 million.

We booked 33 new design licenses including 14 for the ARCtangent processor and
19 licenses for USB in the first nine months of the year. We also continue to
license more than 50 different software customers each quarter.

Both income from royalties and the Asian operations achieved record levels and
have grown sequentially throughout all three quarters this year.

Product Strategy and Customer Focus

Providing vertically integrated products continues to be a primary focus for
ARC. Many of our customers are developing innovative consumer electronics
applications. Products such as the audio codecs, provide them with the
technology that helps them get to market more quickly by reducing the number of
IP vendors necessary to complete designs. Applications that can use one or more
of our codecs include: digital still cameras, cell phones and personal video
recorders.

ARC has also made progress in reducing the number of IP vendors our networking
customers need to complete designs. In August, ARC introduced IPShield(TM) and
ARCProtect(TM) two new security software products for embedded networking
applications. With these two products, ARC provides designers with the ability
to incorporate Internet Security to their network connected devices.

Major semiconductor companies are continuing to adopt ARC's technology. In the
third quarter ARC expanded its business relationships in Asia with:

Kawasaki Microelectronics, with world-wide design centers, licensed the
ARCtangent(TM) processor, ARC's class leading audio codecs and the MetaWare(TM)
Tool Suite.

MSILICON Electronics, located in Hsin Chu, Taiwan, is the first Asian-based
company to license ARC's High-Speed USB 2.0 On-the-Go technology. They will
integrate ARC's USB 2.0 OTG into a development platform for multimedia storage
devices.

Sony Semiconductor Kyushu licensed the ARCtangent processor, for a variety of
projects, because it delivers more computational power, but draws less power
than other combined RISC/DSP implementations. The relationship with Sony
broadens ARC's presence in Japan's consumer electronics market.

ARC's technology has also been employed in some innovative digital media
applications this past quarter.

SandVideo, of Andover, MA, a recognized expert in motion video compression
semiconductor technology, plans to integrate multiple ARCtangent processors into
its next generation video compression codecs, because the flexibility of the
cores enables them to respond more rapidly to changing industry specifications

ViewAhead Technology, a long time ARC customer, introduced the
ViewFleX500(TM) the first USB Now(TM)-based product to reach the
market. ViewAhead integrated ARC's USB Now into its digital imaging
print controller for the personal document imaging market, because the
integration provided by USB Now allowed ViewAhead to spend its time
and silicon budget on application-specific innovation. The ViewFleX500
began shipping in the third quarter.

Sandisk Corporation, the world's largest supplier of flash memory data storage
card products, introduced a new family of compact flash controllers in August.
SanDisk selected the ARCtangent processor core for its Ultra II Compact Flash
and Ultra II SD card because it enables very high bandwidth data transfer from
the host bus to the NAND memory and reduces to a minimum the processing
overhead.

ARC 600(TM) and USB

ARC 600 Processor

ARC introduced a new configurable processor architecture for power-sensitive
embedded systems at the Microprocessor Forum on 15 October 2003. The ARC 600,
the industry's smallest and lowest power 32-bit RISC/DSP, targets
high-performance multimedia-intensive applications and lends itself to
multiprocessing designs. With the ARC 600 architecture's configurability and
extendibility, designers have the necessary tools to balance the processor's
speed, area and power to develop an optimal solution for their specific
application.

USB Host Controllers

ARC extended its leadership position within the USB IP market with the
introduction of a new family of host-specific USB products in September.
Host-only functionality is critical as a large number of USB applications are in
the process of migrating from exclusively USB full speed to a combination of
full- and high-speed ports. The new family of host controllers is targeted at
"PC-less" printing. They are optimized for set-top boxes, high-end video gaming
systems, residential gateway devices and printer applications.

Audio Codecs

In keeping with our platform approach to decreasing development risk for our
customers, ARC introduced a family of digital audio codecs this quarter. These
codecs are optimized for use on the ARCtangent(TM)-A5 processor. Like the
previously introduced VoIP codecs, these devices leverage the DSP extension
instructions of the A5 to deliver high performance audio decoding and encoding.
In a matter of minutes, designers can easily create a microprocessor tailored
for their voice or audio needs, dramatically reducing development time and cost.

Software and Development Tools

Security for Embedded Applications

Early in the third quarter, ARC introduced two products aimed at satisfying the
crucial requirements for transmitting sensitive information over the Internet.
IPShield(TM) software, is an Internet security solution providing embedded
designers with the ability to build security into their network-connected
systems. ARCProtect(TM) is a hardware-acceleration, within the ARCtangent, of
IPShield algorithms. These products are intended for applications such as small
office/home office routers, xDSL/cable modems and security equipment.

Strategic Alliances

Metrowerks, a division of Motorola(R), and ARC continue to strengthen
their strategic relationship. In August, the two companies joined
forces to announce support for Motorola(R) ColdFire(TM) MPC852T Power
QUICC I processor. The resulting product, the MPC852 Evaluation
System, which includes ARC's software suite, provides an easy-to-use,
cost-effective prototyping solution for embedded system engineers
developing MPC852T processor-based networking and communications
applications.

Partnering with Samsung, ARC has released a robust software support solution for
Samsung's high performance, cost-effective, ARM-based S3C25xx communications
processors. ARC is offering its MQX RTOS, RTCS TCP/IP networking stack, a
variety of networking protocols, security software and USB device stack for
engineers developing S3C25xx-based networking and communications applications
for the router, WLAN and firewall markets.

Organization Update

This week, we announced a re-organisation of the workforce to better focus our
resources and increase efficiencies. The business will be restructured into
three separate Business Units: the Processor Business Unit, Peripherals Business
Unit and Software Business Unit. In conjunction with these changes, we have
announced a 10% reduction in our workforce. This will impact approximately 20
jobs. To this end, we expect to take a nominal charge in the fourth quarter.

Outlook

We introduced a number of new products across the processor, peripheral and
software business units in Q3 and we expect shipments of these new products to
have greater impact in the upcoming periods.

Our cost reduction efforts implemented this week will further optimize our cost
structure. We are pleased with the increases in royalty and Asia income and
expect to maintain the momentum in these segments alongside any improvements in
the overall industry.

Three months ended 30 September 2003

Turnover

Total turnover for the third quarter was �2.5 million, up 5% from the second
quarter turnover of �2.4 million and down 9% year over year (Q3 2002: �2.8
million). Prior to currency translation, with virtually all sales in US$,
underlying turnover was up 3% sequentially and down 6% over Q3 2002. License
income was 2% lower than the previous quarter at �1.5 million (Q2 2003: �1.5
million). Maintenance and service income was 5% lower than the previous quarter
at �0.5 million (Q2 2003: �0.5 million). The number of designs being shipped by
our customers and contributing to royalties increased significantly resulting in
a 40% increase in royalties to �0.5 million (Q2 2003: �0.4million).
