Conditions and Trends in Our Industry
   Summary of Our Financial Performance in the First Quarter of Fiscal 2006
   
    
    In Japan, revenues decreased by 52% or $1.7 million, primarily due to competition from test products developed by
two of our Japanese OEM customers, both for their own internal use and for sale to our
major Japanese telecom operator customers. We expect this competitive factor to continue to
impact our Japanese revenues for at least the remainder of our current fiscal year.
Revenues in Japan were also impacted by a 10% decrease in the value of the yen, in which
all our revenues in Japan are denominated.
    
    In regions outside Japan, we were unable to recognize $2.5 million in revenue due to
engineering delays resulting from the length of time and level of resources required to
complete our common hardware platform.
    
    Our overall gross profit margin decreased by six percentage points due to increases in
hardware component costs and services demonstration equipment costs as a percentage of the
related revenues.
    
    In the first quarter of fiscal 2006, we recorded $0.6 million in pre-tax, non-cash,
stock-based compensation expense under the newly applicable accounting standard, SFAS
123(R), Share-Based Payment.Because
we elected to adopt this standard under the modified prospective transition method, we did not
restate prior periods to include stock-based compensation expense.
Refer to Stock-Based Compensation in the Critical
Accounting Policies and Estimates section below.

  Risks Related to Our Business
 Our quarterly operating results may fluctuate significantly, and this may result in volatility in
the market price of our common stock.
  
    
    the variable size and timing of individual purchases by our customers;
    
    absence of long-term customer purchase contracts;
    
    seasonal factors that may affect capital spending by customers, such as the varying
fiscal year ends of customers and the reduction in business during the summer months,
particularly in Europe;
    
    the relatively long sales cycles for our products;
    
    competitive conditions in our markets;
    
    exchange rate fluctuations;
    
    the timing of the introduction and market acceptance of new products or product
enhancements by us and by our customers, competitors and suppliers;
    
    costs associated with developing and introducing new products;
    
    product life cycles;
    
    changes in the level of operating expenses relative to revenues;
    
    product defects and other quality problems;
    
    customer order deferrals in anticipation of new products;
    
    supply interruptions;
    
    changes in global or regional economic conditions or in the telecommunications industry;
    
    delays in purchasing decisions or customer orders due to customer consolidation;
    
    the ability to hire sales and technical personnel;
    
    changes in the mix of products sold;
    
    variability in stock-based compensation expense and the associated impact on our effective tax rate; and
    
    changes in the regulatory environment.

##### Table of Contents



Historically, our revenues have been dependent upon a few significant customers, the loss of one
or more of which could significantly reduce our revenues.
  Our business is dependent on our customers outsourcing their telecommunications testing needs, and
our business could be harmed if the market for outsourced testing solutions declines or fails to
grow.
  If we do not effectively manage our growth, our business and operating results could be adversely
affected.
  We face foreign business, political and economic risks because a significant portion of our sales
is to customers outside the United States.
  
    
    longer customer payment cycles;
    
    greater difficulty in accounts receivable collection;
    
    difficulties in staffing and managing foreign operations;
    
    changes in regulatory requirements or in economic or trade policy;
    
    costs related to localizing products for foreign countries;
    
    potentially weaker protection for intellectual property in certain foreign countries;
    
    the burden of complying with a wide variety of foreign laws and practices, tariffs and
other trade barriers; and
    
    potentially adverse tax consequences, including restrictions on repatriation of
earnings.

We face intense competition in our markets from more established test solutions providers, and if
we are unable to compete successfully we may not be able to maintain or grow our business.
  Our success depends on the continued growth of the telecommunications industry and increased use
of our test solutions, and lack of growth in this industry could harm our business.
   Our business could be harmed if we were to lose the services of one or more members of our
senior management team, or if we are unable to attract and retain qualified personnel.

We may not be able to achieve the anticipated benefits of any acquisitions we may make of other
companies, products or technologies.
  
    
    difficulties associated with assimilating the personnel and operations of acquired companies;
    
    potential disruption of our ongoing business;
    
    distraction of management and other resources;
    
    integration of personnel and technology of an acquired company;
    
    difficulties in evaluating the technology of a potential target;
    
    inability to motivate and retain new personnel;
    
    maintenance of uniform standards, controls, procedures and policies; and
    
    impairment of relationships with employees and clients as a result of the integration
of new management personnel.
  Many of our suppliers are sole source or single source suppliers, and our inability to obtain
adequate amounts of components from these suppliers could harm our business.
  We depend on a limited number of independent manufacturers, which reduces our ability to control
our manufacturing process.

The high level of complexity and integration of our products increases the risk of latent defects,
which could damage customer relationships and increase our costs.
  We face exposure to product liability claims, which if successful could harm our business.
  Our success is dependent on our ability to protect our intellectual property, and our failure to
protect our intellectual property could have a significant adverse impact on our business.
  We could become subject to litigation regarding intellectual property, which could divert
management attention, be costly to defend and prevent us from using or selling the challenged
technology.

   Risks Related to Our Stock
 Our stock has been, and likely will continue to be, subject to substantial price and volume
fluctuations due to a number of factors, many of which will be beyond our control.
  
    
    quarterly variations in our operating results;
    
    changes in our revenue growth rates as a whole or for specific geographic areas or products;
    
    changes in earning estimates by market analysts;
    
    the announcements of new products or product enhancements by us or our competitors;
    
    speculation in the press or analyst community; and
    
    general market conditions or market conditions specific to particular industries.
  If we are unable to determine and demonstrate that we maintain effective internal control over
financial reporting, this may cause investors to lose confidence in our reported financial
information and the price of our stock could drop significantly.
