Spectrum Signal Processing and General Dynamics to Introduce
Upgraded Modem for U.S. Navy Digital Modular Radios (DMR)

COLUMBIA, MD — July 14, 2005 — Spectrum Signal Processing (USA) Inc. (NASDAQ:SSPI/TSX: SSY) and General Dynamics C4 Systems, a business unit of General Dynamics (NYSE: GD), announced today that the companies will introduce and market an upgraded wideband modem for the U.S. Navy’s AN/USC-61(C) Digital Modular Radio (DMR). The upgrade will allow the DMR, a software-defined radio, to host new wideband Joint Tactical Radio System (JTRS) waveforms, in addition to the existing range of waveforms supported.

The upgraded modem, which was demonstrated to the Navy in late 2004, will enable advanced communications capabilities consistent with JTRS requirements using cost-effective, commercial-off-the-shelf (COTS) technology. General Dynamics has shipped approximately 300 software-defined radios, each with four channels, to the Navy to be installed on ships, submarines, shore sites, and test facilities. The new modem capability will permit the hosting of high-speed networking waveforms to operate over multiple channels on the DMR platform.

“This wideband modem upgrade will now complete the picture by enabling true wideband networking capability,” said Chris Brady, Vice President of Assured Communication Systems for General Dynamics C4 Systems. “In fielding the software-defined Digital Modular Radio to the Navy, General Dynamics has already delivered many of the challenging capabilities required for certification by JTRS.”

Spectrum USA will supply advanced modem technology that General Dynamics will integrate on the DMR platform. Spectrum USA and General Dynamics have successfully collaborated on a number of projects for military communications and signals intelligence.

James P. Atkins, President of Spectrum USA, said, “By leveraging our combined expertise in software defined radios, the General Dynamics-Spectrum USA team will shorten the development cycle to quickly bring new and robust functionality to Navy communications.”

The DMR system is a National Security Agency-certified software defined radio that currently features some JTRS capabilities such as expanded frequency range, multiple software-defined waveforms, multiple independent level security, advanced software and has completed UHF SATCOM waveform conformance testing at Joint Interoperability Test Command (JITC). The system can be used to replace multiple existing radios with a single, easy-to-use system; on certain Navy platforms, it can reduce equipment space requirements by more than 50 percent.

Spectrum Signal Processing Reports Preliminary Second Quarter 2005 Results

Burnaby, B.C., Canada — July 14, 2005 — Spectrum Signal Processing Inc. today announced its preliminary second quarter results. This release is made to provide full disclosure to the market concurrent with the Company’s announcement of the introduction of a wideband modem upgrade for the US Navy’s AN/USC-61(C) Digital Modular Radio (DMR) with General Dynamics C4 Systems.

Revenues for the company’s second quarter of 2005 are expected to be $3.3 million to $3.5 million. Wireless product and service revenues are expected to be $3.1 million to $3.3 million and packet-voice product and service revenues are expected to be $0.2 million to $0.3 million. The company’s gross profit is expected to be between $2.0 million and $2.1 million representing a gross margin of approximately 59% — 61% of revenues. Operating expenses are expected to be in the $2.4 million to $2.6 million range. The company expects a net loss of between $0.3 million and $0.6 million, or $0.02 to $0.03 per share.

Spectrum anticipates its cash position, net of bank indebtedness, at June 30, 2005 to be approximately $3.4 million, compared to $3.9 million at March 31, 2005.

Spectrum anticipated a substantial decline in packet-voice revenues in 2005 following its decision in early 2004 to cease all new investment in its packet-voice product line. Second quarter and first half of 2005 packet-voice revenues have declined approximately $1.0 million and $2.1 million relative to the same periods in 2004. Conversely, the company’s core wireless product and service revenues have increased over $1.0 million relative to the first half of 2004.

As Spectrum continues to focus its product portfolio and sales activities on wireless C4ISR programs, its operations are becoming increasingly linked with U.S. government procurement cycles. As such, the company sees stronger initial design-in and revenue opportunities in the second half of 2005.

Spectrum will report its second quarter 2005 financial and operating results on July 27, 2005. The company will provide additional information, including a more detailed quarterly review during its regularly scheduled conference call on that date, the details of which will be announced shortly.
