Mississauga, Ontario (December 4, 2007) – Certicom Corp. (TSX: CIC) (“Certicom” or the “Company”) today reported results for the second quarter of fiscal 2008 ended October 31, 2007. All figures are in U.S. dollars and in accordance with Canadian Generally Accepted Accounting Principles (GAAP) except where otherwise noted.

Revenue for the quarter was $3.8 million compared to $5.9 million for the second quarter of fiscal 2007. For the first six months of fiscal 2008, revenue was $7.0 million, compared to $10.6 million in the first six months of fiscal 2007.

“While we are disappointed with the revenue for the first half of the year, I will reiterate that we have not lost any prospective deals for this time period,” said Bernard Crotty, Certicom’s President and Chief Executive Officer. “Our pipeline of opportunities continues to grow by quantity and quality. As the Texas Instruments and Bally Technologies agreements demonstrate, leading technology companies are embracing Certicom’s complete security solutions.”

Mr. Crotty continued, “As we stated in our pre-release last month, our second quarter revenue fell short of expectations due to a combination of factors. These included the complex nature of the strategic deals we focus on and our product development shift towards total security solutions. I will point out again that we may encounter revenue variability, including upside variability, over the next few quarters as we adapt to changing market dynamics, progress through the Sony patent litigation case, and proceed with executing our growth strategy.”

SECOND QUARTER FINANCIAL REVIEW

Operating expenses1 for the quarter were $5.0 million, compared to $4.6 million in the second quarter of fiscal 2007. The increase in year-over-year operating expenses was mainly due to legal expenses related to the Sony litigation. However, the operating expenses were lower than the guidance given in the previous quarter due to lower than expected litigation expenses, which totaled $0.4 million for the quarter. The Company posted a net loss on a GAAP basis of $2.8 million, or $0.06 per basic and diluted share for the quarter, compared to net earnings of $0.6 million, or $0.01 per basic and diluted share in the second quarter of fiscal 2007.

The Company reports that recurring revenue for the second quarter was $2.0 million, consistent with $2.1 million in the second quarter of fiscal 2007.

Certicom had $40.4 million in cash2 at quarter-end compared to $43.2 million at year-end fiscal 2007 and $44.4 million at October 31, 2006. The Company has no debt.

SIX MONTH FINANCIAL REVIEW

Operating expenses1 for the first six months of fiscal 2008 were $10.7 million compared to $9.0 million for the same period last year. The increase in year-over-year operating expenses was mainly due to legal expenses related to the Sony litigation and a planned increase in product development resources specifically related to new product initiatives.

For the first six months of fiscal 2008, the Company posted a net loss on a GAAP basis of $6.2 million or $0.14 per basic and diluted share, compared to a net loss of $0.7 million, or $0.02 per basic and diluted share for the same period last year.

The Company reports that recurring revenue for the six-month period was $4.0 million, consistent with $4.1 million for the same period in fiscal 2007.

UPDATE ON SONY PATENT INFRINGEMENT LITIGATION

Sony answered Certicom's patent infringement complaint on August 31, 2007, denying infringement and asserting invalidity. Certicom remains confident in its legal position and in its ability to successfully pursue this litigation.

In pursuing the Sony litigation, Certicom management expects to receive a reasonable royalty on the sales of Sony products that Certicom alleges use its ECC technology in content protection technologies, such as Advanced Access Control System (AACS) and Digital Transmission Content Protection (DTCP).

Certicom is currently progressing through the broad discovery phase in which both parties are required to provide certain documentation.

CEO SEARCH

The Company expects to make an announcement regarding the appointment of Certicom’s new CEO by December 31, 2007.

OUTLOOK

Management intends to continue its focus on leveraging Certicom's global leadership position in ECC to build recurring revenue and sustainable profits. The Company is committed to five key strategies for maximizing market share: partnering for continued ECC adoption, expanding its global sales presence, investing in new product development, pursuing acquisitions, and defending its patent portfolio.

Operating expenses1 for the second quarter of fiscal 2008, excluding cost of revenues, depreciation and amortization, and stock-based compensation, are expected to range from $6.1 to $6.5 million, including estimated legal expenses ranging from $0.6 to $1.0 million associated with intellectual property protection. Management continues to aggressively manage expenses to achieve a cost structure that is in line with revenue, which is key to Certicom's goal of achieving sustainable, profitable growth.
