Sandvine Updates 2008 Revenue Outlook, Provides Estimated Q1 2008 Revenue

Waterloo, Canada; March 6, 2008 – Sandvine (TSX:SVC; AIM:SAND), a leading provider of intelligent broadband network solutions for DSL, FTTH, cable, and wireless carriers, has updated its annual revenue estimate, previously reported on December 20, 2007 and referenced in Sandvine’s press release of January 16, 2008. Sandvine now expects total revenue for fiscal 2008 to be in the range of $80 million and $85 million (compared to the previously announced range of $100 million to $110 million).

In arriving at this revenue estimate, Sandvine has relied upon the following material assumptions:

• Fifty percent of the revenue target will be earned from existing customers;
• The other fifty percent of the revenue target will be earned from new customers, which would include revenue from four to six new “tier one” service providers (service providers with over one million broadband/mobile data subscribers) from the DSL and wireless markets, combined;
• Sales through channel partners will account for approximately 15% to 20% of the revenue target; and
• The Canadian dollar will be at par with the US dollar for the year.

Preliminary results for the first quarter ended February 29, 2008 indicate revenue to be approximately $8.2 million.

The above estimates constitute forward-looking information. See “Caution Regarding Forward-Looking Information below.

“The Q1 opportunities we have been pursuing still exist, but customers are taking longer to make decisions and, although we do not evaluate the strength of our business on the results in any one particular quarter, we think it’s prudent to adjust our annual revenue estimate at this time,” said Dave Caputo, Sandvine’s President and Chief Executive Officer. “We believe that the delays have come about for a variety of reasons, ranging from unique customer-specific circumstances to economic conditions, making operators pause before executing on their approved budgets. We can’t dictate when customers make their decisions, just influence whether they choose Sandvine - and we remain as confident as ever in our ability to do that.”
