    Litigation settlement charges of $5.4 million were recognized in the three and six
months ended June 30, 2006, respectively, in connection with settlement agreements reached
separately, by Foundry with Lucent and AlcatelLucent. Litigation settlement charges
pertained primarily to the accrual of costs incurred and payable to Lucent and
AlcatelLucent related to past periods.
    
    For the three months ended June 30, 2007 and 2006, costs of $3.1 million and $0.3
million were incurred, respectively, for the independent review of our stock option
practices and for the six months ended June 30, 2007 and 2006, costs of $5.6 million and
$0.3 million were incurred, respectively, related to this review. The remaining costs
associated with the review should not be material going forward; however, we do expect to
record approximately $2.5 million in operating expenses in future periods related to the
assumption of employee 409A taxes associated with 2006 exercises of stock option grants
with revised measurement dates associated with our tender offer.

We must continue to introduce new products with superior performance and features in a timely
manner in order to sustain and increase our revenue, and if we fail to predict and respond to
emerging technological trends and customers changing needs, our operating results may suffer.
   We depend on large, recurring purchases from certain significant customers, and a loss,
cancellation or delay in purchases by these customers could negatively affect our revenue.
   
    
    our reseller agreements generally do not require minimum purchases;
    
    our customers can stop purchasing and our resellers can stop marketing our products at any time; and
    
    our reseller agreements generally are not exclusive and are for one-year terms, with no
obligation of the resellers to renew the agreements.

The United States government is a significant customer and has been one key to our financial
success. However, government demand is unpredictable and there is no guarantee of future contract
awards.
  The matters relating to our Special Committee investigation into our stock option granting
practices and the restatement of our financial statements have exposed us to civil litigation
claims, regulatory proceedings and government proceedings which could burden Foundry and have a
material adverse effect on us.
  We may be subject to litigation risks and intellectual property infringement claims that are costly
to defend and could limit our ability to use certain technologies in the future. Additionally, we
may be found to infringe on intellectual property rights of others.

If we fail to protect our intellectual property, our business and ability to compete could suffer.
   Our ability to increase our revenue depends on expanding our direct sales operations and reseller
distribution channels and providing excellent customer support.
   Because our financial results are difficult to predict and may fluctuate significantly, we may not
meet quarterly financial expectations, which could cause our stock price to decline.

As a result, our business may be harmed if we are unable to successfully address these risks.

   Due to the lengthy sales cycles of some of our products, the timing of our revenue is difficult to
predict and may cause us to fail to meet our revenue expectations.
  We are required to expense equity compensation given to our employees, which has reduced our
reported earnings, will significantly impact our operating results in future periods and may reduce
our stock price and our ability to effectively utilize equity compensation to attract and retain
employees.
  As a result of our delayed filing of our periodic SEC reports, our inability to maintain our Form
S-3 eligibility may adversely affect our ability to raise future capital or complete acquisitions.
  If we do not adequately manage and evolve our financial reporting and managerial systems and
processes, our ability to manage and grow our business may be harmed.

We had a material weakness in internal control over financial reporting in the past and cannot
assure you that additional material weaknesses will not be identified in the future. If our
internal control over financial reporting or disclosure controls and procedures are not effective,
there may be errors in our financial statements that could require a restatement or our filings may
not be timely and investors may lose confidence in our reported financial information, which could
lead to a decline in our stock price.
