| “Management’s Discussion and Analysis of Financial Condition and Results of     Operations” and all other statements contained in this report that are not     statements of historical fact, including without limitation, statements     containing the words “believes,” “expects,” “projections” and words of     similar meaning, constitute forward-looking statements that involve a number     of risks and uncertainties that are difficult to predict | 
    
      | Forward-looking     statements regarding financial performance in future periods, including the     statements under “Outlook for 2006”, do not reflect potential impacts of     mergers or acquisitions or other significant transactions or events that     have not been announced as of the time the statements are made | 
    
      | Actual     outcomes  and  results may differ materially from what is expressed or     forecast in forward-looking statements | 
    
      | We disclaim any obligation to update     forward-looking statements to reflect future events or revised expectations | 
    
      | The following discussion highlights factors that could cause actual results     to  differ  materially  from  the  results expressed or implied by our     forward-looking statements | 
    
      | Forward-looking statements should be considered     in light of these factors | 
    
      | Weakness in the United States and international economies may materially     adversely impact us | 
    
      | The  United States and international economies can experience economic     downturns,  which may have a material adverse affect on our results of     operations | 
    
      | Weakness in these economies may materially adversely impact the     timing and receipt of orders for our products and our results of operations | 
    
      | Revenue levels are dependent on the level of technology capital spending,     which  includes  worldwide expenditures for EDA software, hardware and     consulting services | 
    
      | In addition, mergers and company restructurings in the     worldwide electronics industry may materially adversely impact demand for     our products and services resulting in decreased or delayed capital spending     patterns | 
    
      | We  are  subject  to the cyclical nature of the integrated circuit and     electronics systems industries and any future downturns may materially     adversely impact us | 
    
      | Purchases of our products and services are highly dependent upon new design     projects  initiated  by  customers  in the integrated circuit (IC) and     electronics systems industries | 
    
      | These industries are highly cyclical and are     subject  to  constant  and  rapid  technological change, rapid product     obsolescence, price erosion, evolving standards, short product life cycles     and wide fluctuations in product supply and demand | 
    
      | The IC and electronics     systems  industries  regularly experience significant downturns, often     connected with, or in anticipation of, maturing product cycles within such     companies and/or a decline in general economic conditions | 
    
      | These downturns     cause diminished product demand, production overcapacity, high inventory     levels  and accelerated erosion of average selling prices | 
    
      | During such     downturns, the number of new design projects generally decreases, which can     materially adversely impact demand for our products and services | 
    
      | Our forecasts of our revenues and earnings outlook may be inaccurate and     could materially adversely impact our business or our planned results of     operations | 
    
      | Our revenues, particularly new software license revenues, are difficult to     forecast | 
    
      | We  use a “pipeline” system, a common industry practice, to     forecast revenues and trends in our business | 
    
      | Sales personnel monitor the     status  of potential business and estimate when a customer will make a     purchase  decision,  the dollar amount of the sale and the products or     services to be sold | 
    
      | These estimates are aggregated periodically to generate     a sales pipeline | 
    
      | Our pipeline estimates may prove to be unreliable either     in a particular quarter or over a longer period of time, in part because the     “conversion rate” of the pipeline into contracts can be very difficult to     estimate and requires management judgment | 
    
      | A variation in the conversion     rate could cause us to plan or budget incorrectly and materially adversely     impact our business or our planned results of operations | 
    
      | In particular, a     slowdown in customer spending or weak economic conditions generally can     reduce the conversion rate in a particular quarter as purchasing decisions     are delayed, reduced in amount or cancelled | 
    
      | The conversion rate can also be     affected by the tendency of some of our customers to wait until the end of a     quarter in the hope of obtaining more favorable terms | 
    
      | Fluctuations in quarterly results of operations due to customer seasonal     purchasing  patterns,  the timing of significant orders and the mix of     licenses used to sell our products could materially adversely impact our     business and the market price of our common stock | 
    
      | We  have experienced, and may continue to experience, varied quarterly     operating results | 
    
      | Various factors affect our quarterly operating results     and some of these are not within our control, including customer demand and     the timing of significant orders | 
    
      | We experience seasonality in demand for     our products, due to the purchasing cycles of our customers, with revenues     in the fourth quarter generally being the highest | 
    
      | We receive a majority of     our software product revenues from current quarter order performance, of     which a substantial amount is usually booked in the last few weeks of each     quarter | 
    
      | A significant portion of our revenues come from multi-million     dollar contracts, the timing of the completion of and the terms of delivery     of which can have a material impact on revenue for a given quarter | 
    
      | If we     fail to receive expected orders, particularly large orders, our revenues for     that quarter could be materially adversely impacted | 
    
      | In such an event, we     could fail to meet investors’ expectations, which could have a material     adverse impact on our stock price | 
    
      | 7     ______________________________________________________________________    [32]Table of Contents       Our revenues are also affected by the mix of licenses entered into where we     recognize software product revenues as payments become due and payable or     ratably over the license term as compared to revenues recognized at the     beginning  of the license term | 
    
      | We recognize revenues ratably over the     license term when the customer is provided with rights to unspecified or     unreleased future products | 
    
      | A shift in the license mix toward increased     ratable or due and payable revenue recognition would result in increased     deferral of software product revenues to future periods and would decrease     current revenues, resulting in not meeting near-term revenue expectations | 
    
      | The gross margin on our software products is greater than that for our     hardware products, software support and professional services | 
    
      | Therefore,     our gross margin may vary as a result of the mix of products and services     sold | 
    
      | Additionally, the gross margin on software products varies year to     year depending on the amount of royalties due to third parties for the mix     of products sold | 
    
      | We also have a significant amount of fixed or relatively     fixed costs, such as employee costs and purchased technology amortization,     and  costs  which  are  committed  in advance and can only be adjusted     periodically | 
    
      | As a result, a small failure to reach planned revenues would     likely have a relativity large negative effect on resulting earnings | 
    
      | If     anticipated revenues do not materialize as expected, our gross margins and     operating results would be materially adversely impacted | 
    
      | We use fixed-term license agreements as a standard business practice with     customers we believe are credit-worthy | 
    
      | These multi-year, multi-element term     license agreements are typically three years in length and have payments     spread over the license term | 
    
      | The complexity of these agreements tends to     increase the risk associated with collectibility from customers that can     arise  for  a  variety  of  reasons  including ability to pay, product     dissatisfaction, disagreements and disputes | 
    
      | If we are unable to collect     under  any  of  these  multi-million dollar agreements, our results of     operations could be materially adversely impacted | 
    
      | We use these fixed-term     license agreements as a standard business practice and has a history of     successfully collecting under the original payment terms without making     concessions on payments, products or services | 
    
      | If we no longer had a history     of collecting without providing concessions on term agreements, then revenue     would be required to be recognized as the payments become due and payable     over the license term | 
    
      | This change would have a material impact on our     results | 
    
      | Accounting rules governing revenue recognition may change | 
    
      | The  accounting rules governing software revenue recognition have been     subject to authoritative interpretations that have generally made it more     difficult to recognize software product revenues at the beginning of the     license period | 
    
      | If this trend continues, new and revised standards and     interpretations  could materially adversely impact our ability to meet     revenue expectations | 
    
      | Forecasting our tax rates is complex and subject to uncertainty | 
    
      | Forecasts of our income tax position and resultant effective tax rate are     complex and subject to uncertainty as our income tax position for each year     combines: (a) the effects of a mix of profits (losses) earned by us and our     subsidiaries in tax jurisdictions with a broad range of income tax rates,     (b) benefits from available deferred tax assets, (c) taxes, interest or     penalties resulting from tax audits and (d) changes in tax laws or the     interpretation of such tax laws | 
    
      | In order to forecast our global tax rate,     pre-tax profits and losses by jurisdiction are estimated and tax expense by     jurisdiction is calculated | 
    
      | If the mix of profits and losses or effective     tax rates by jurisdiction are different than those estimates, our actual tax     rate could be materially different than forecast | 
    
      | New accounting standard related to equity compensation will cause us to     recognize an additional expense, which will result in a reduction in our net     income | 
    
      | In December 2004, the FASB issued SFAS Nodtta 123R, “Share-Based Payment”,     which replaces SFAS Nodtta 123 and supercedes APB Opinion Nodtta 25, relating to     the accounting for equity-based compensation | 
    
      | This statement requires us to     record  a  charge  to compensation expense for stock option grants | 
    
      | We     currently account for stock options under SFAS Nodtta 123, “Accounting for     Stock-Based Compensation” | 
    
      | As permitted by SFAS Nodtta 123, we have elected to     use the intrinsic value method prescribed by Accounting Principles Board     Opinion (APB) Nodtta 25, “Accounting for Stock Issued to Employees,” to measure     compensation expense for stock-based awards granted to employees, under     which the granting of stock options is not considered compensation if the     option exercise price is not less than the fair market value of the common     stock at the grant date | 
    
      | Starting in January 2006, the FASB’s statement     requires that stock-based awards be accounted for using a fair-value based     method, which will require us to measure the compensation expense for all     such awards, including stock options, at fair-value at the grant date | 
    
      | In     Note 2, “Summary of Significant Accounting Policies,” in Item 8, “Financial     Statements and Supplementary Data,” we calculate pro forma net income and     earnings per share as if we had used a fair value-based method similar to     the methods required under SFAS 123R to measure the compensation expense for     employee stock awards during the periods presented | 
    
      | 8     ______________________________________________________________________    [33]Table of Contents       Our  business  is  subject to evolving corporate governance and public     disclosure  regulations that have increased both costs and the risk of     noncompliance, which could have a material adverse impact on us | 
    
      | Because our common stock is publicly traded on the NASDAQ Stock Market, we     are subject to rules and regulations promulgated by a number of governmental     and self-regulated organizations, including the SEC, NASDAQ and the Public     Company Accounting Oversight Board, which monitors the accounting practices     of public companies | 
    
      | Many of these regulations continue to evolve, making     compliance  difficult  and  uncertain | 
    
      | In  particular, Section 404 of     Sarbanes-Oxley Act of 2002 and related regulations have required us to     include a management assessment of our internal controls over financial     reporting and auditor attestation of that assessment in our annual reports | 
    
      | This  effort has required, and continues to require, the commitment of     significant financial and managerial resources | 
    
      | A failure to complete a     favorable  assessment and obtain an auditors’ attestation could have a     material adverse impact on us | 
    
      | The  outcome  of  Internal  Revenue  Service and other tax authorities     examinations could have a material adverse affect on us | 
    
      | The Internal Revenue Service and other tax authorities regularly examine our     income tax returns | 
    
      | Significant judgment is required in determining the     provision for income taxes | 
    
      | In determining the adequacy of income taxes, we     assess  the likelihood of adverse outcomes resulting from the Internal     Revenue  Service and other tax authorities’ examinations | 
    
      | The ultimate     outcome of these examinations cannot be predicted with certainty | 
    
      | Should the     Internal Revenue Service or other tax authorities assess additional taxes as     a result of examinations, we may be required to record charges to operations     that could have a material impact on the results of operations, financial     position or cash flows | 
    
      | There are limitations on the effectiveness of controls | 
    
      | We do not expect that disclosure controls or internal control over financial     reporting will prevent all error and all fraud | 
    
      | A control system, no matter     how well designed and operated, can provide only reasonable, not absolute,     assurance that the control system’s objectives will be met | 
    
      | Further, the     design of a control system must reflect the fact that there are resource     constraints and the benefits of controls must be considered relative to     their costs | 
    
      | Because of the inherent limitations in all control systems, no     evaluation of controls can provide absolute assurance that all control     issues and instances of fraud, if any, have been detected | 
    
      | Failure of our     control systems to prevent error or fraud could materially adversely impact     us | 
    
      | The lengthy sales cycle for our products and services and delay in customer     consummation of projects, make the timing of our revenues difficult to     predict | 
    
      | We have a lengthy sales cycle that generally extends between three and six     months | 
    
      | A lengthy customer evaluation and approval process is generally     required due to the complexity and expense associated with our products and     services | 
    
      | Consequently,  we may incur substantial expenses and devote     significant management effort and expense to develop potential relationships     that  do  not result in agreements or revenues and may prevent us from     pursuing  other  opportunities | 
    
      | In addition, sales of our products and     services may be delayed if customers delay approval or commencement of     projects due to customers’ budgetary constraints, internal acceptance review     procedures, timing of budget cycles or timing of competitive evaluation     processes | 
    
      | Any loss of our leadership position in certain segments of the EDA market     could have a material adverse affect on us | 
    
      | The industry in which we compete is characterized by very strong leadership     positions in specific segments of the EDA market | 
    
      | For example, one company     may enjoy a large percentage of sales in the physical verification segment     of  the  market while another will have a similarly strong position in     mixed-signal simulation | 
    
      | These strong leadership positions can be maintained     for significant periods of time as the software is difficult to master and     customers are disinclined to make changes once their employees, as well as     others  in  the industry, have developed familiarity with a particular     software product | 
    
      | For these reasons, much of our profitability arises from     niche areas in which we are the strong leader | 
    
      | Conversely, it is difficult     for us to achieve significant profits in niche areas where other companies     are the leaders | 
    
      | If for any reason we lose our leadership position in a     niche, we could be materially adversely impacted | 
    
      | We may not realize revenues as a result of our investments in research and     development | 
    
      | We incur substantial expense to develop new software products | 
    
      | Research and     development activities are often performed over long periods of time | 
    
      | This     effort may not yield a successful product offering or the product may not     satisfy customer requirements | 
    
      | As a result, we would realize little or no     revenues related to our investment in research and development | 
    
      | Intense competition in the EDA industry could materially adversely impact     us | 
    
      | Competition in the EDA industry is intense, which can lead to, among other     things, price reductions, longer selling cycles, lower product margins, loss     of  market  share  and additional working capital requirements | 
    
      | If our     competitors offer significant discounts on certain products, we may need to     lower  our  prices  or offer other favorable terms in order to compete     successfully | 
    
      | Any  such changes would likely reduce margins and could     materially adversely impact our operating results | 
    
      | Any broad-based changes     to our prices and pricing policies could cause new software license and     service revenues to decline or be delayed as the sales force implements and     our customers adjust to the new pricing policies | 
    
      | Some of our competitors     may bundle software products for promotional purposes or as a long-term     pricing strategy | 
    
      | These practices could significantly constrain prices we     can charge for our products | 
    
      | Our success depends upon our ability to acquire     or  develop  and  market products and services that are innovative and     cost-competitive and that meet customer expectations | 
    
      | 9     ______________________________________________________________________    [34]Table of Contents       We currently compete primarily with two large companies: Cadence Design     Systems, Inc | 
    
      | and Synopsys, Inc | 
    
      | We compete with numerous smaller companies,     a number of which have combined with other EDA companies | 
    
      | We also compete     with manufacturers of electronic devices that have developed, or have the     capability to develop, their own EDA products internally | 
    
      | We may acquire other companies and may not successfully integrate them | 
    
      | The industry in which we compete has seen significant consolidation in     recent years | 
    
      | During this period, we have acquired numerous businesses and     have frequently been in discussions with potential acquisition candidates,     and  we may acquire other businesses in the future | 
    
      | While we expect to     carefully analyze all potential transactions before committing to them, we     cannot  assure  that  any transaction that is completed will result in     long-term benefits to us or our shareholders or that our management will be     able to manage the acquired businesses effectively | 
    
      | In addition, growth     through acquisition involves a number of risks | 
    
      | If any of the following     events  occurs  after we acquire another business, it could materially     adversely impact us:           •   difficulties in combining previously separate businesses into a single     unit;           •   the substantial diversion of management’s attention from day-to-day     business when integrating the acquired business;           •   the discovery after the acquisition has been completed of previously     unknown liabilities assumed with the acquired business;           •   the failure to realize anticipated benefits, such as cost savings and     increases in revenues;           •   the failure to retain key personnel of the acquired business;           •   difficulties related to assimilating the products of an acquired     business in, for example, distribution, engineering and customer support     areas;           •   unanticipated costs;           •   adverse impacts on existing relationships with suppliers and     customers; and           •   failure to understand and compete effectively in markets in which we     have limited experience | 
    
      | Acquired businesses may not perform as projected, which could result in     impairment of acquisition-related intangible assets | 
    
      | Additional challenges     include integration of sales channels, training and education of the sales     force for new product offerings, integration of product development efforts,     integration of systems of internal controls and integration of information     systems | 
    
      | Accordingly, in any acquisition there will be uncertainty as to the     achievement and timing of projected synergies, cost savings and sales levels     for  acquired products | 
    
      | All of these factors can impair our ability to     forecast, meet revenues and earnings targets and manage effectively our     business for long-term growth | 
    
      | We cannot assure that we can effectively meet     these challenges | 
    
      | Risks  of international operations and the effects of foreign currency     fluctuations can materially adversely impact our business and operating     results | 
    
      | We realize more than half of our revenues from customers outside the United     States and we generate approximately one-third of our expenses outside the     United States | 
    
      | Significant changes in exchange rates can have an adverse     impact  on us | 
    
      | For further discussion of foreign currency effects, see     “Effects  of  Foreign  Currency  Fluctuations”  discussion  in Item 7 | 
    
      | ” In addition, international operations subject us to other risks     including longer receivables collection periods, changes in a specific     country’s or region’s economic or political conditions, trade protection     measures, import or export licensing requirements, loss or modification of     exemptions for taxes and tariffs, limitations on repatriation of earnings     and difficulties with licensing and protecting our intellectual property     rights | 
    
      | The delay in production of components or the ordering of excess components     for our emulation hardware products could materially adversely impact us | 
    
      | The success of our emulation product depends on our ability to procure     hardware components on a timely basis from a limited number of suppliers,     assemble  and  ship systems on a timely basis with appropriate quality     control, develop distribution and shipment processes, manage inventory and     related  obsolescence issues and develop processes to deliver customer     support for hardware | 
    
      | Our inability to be successful in any of the foregoing     could materially adversely impact us | 
    
      | We  commit  to  purchase component parts from suppliers based on sales     forecasts of our emulation products | 
    
      | If we cannot change or be released from     these non-cancelable purchase commitments, and if orders for our products do     not materialize, we could incur significant costs related to the purchase of     excess  components which could become obsolete before we can use them | 
    
      | Additionally, a delay in production of the components could materially     adversely impact our operating results | 
    
      | Our  failure to adequately protect our proprietary rights or to obtain     software or other intellectual property licenses could materially adversely     impact us | 
    
      | Our success depends, in large part, upon our proprietary technology | 
    
      | We     generally  rely on patents, copyrights, trademarks, trade secret laws,     licenses and restrictive agreements to establish and protect our proprietary     rights  in technology and products | 
    
      | Despite precautions we may take to     protect our intellectual property, we cannot assure that third parties will     not  try to challenge, invalidate or circumvent these protections | 
    
      | The     companies in the EDA industry, as well as entities and persons outside the                                           10     ______________________________________________________________________    [35]Table of Contents       industry, are obtaining patents at a rapid rate | 
    
      | Many of these entities have     substantially larger patent portfolios than we have | 
    
      | As a result, we may on     occasion be forced to engage in costly patent litigation to protect our     rights or defend our customers’ rights | 
    
      | We may also need to settle these     claims on terms that are unfavorable; such settlements could result in the     payment of significant damages or royalties, or force us to stop selling or     redesign one or more products | 
    
      | We cannot assure that the rights granted     under our patents will provide us with any competitive advantage, that     patents will be issued on any of our pending applications or that future     patents will be sufficiently broad to protect our technology | 
    
      | Furthermore,     the laws of foreign countries may not protect our proprietary rights in     those countries to the same extent as United States law protects these     rights in the United States | 
    
      | Some  of  our products include software or other intellectual property     licensed from third parties, and we may have to seek new licenses or renew     existing  licenses for software and other intellectual property in the     future | 
    
      | Our failure to obtain software or other intellectual property     licenses or rights on favorable terms could materially adversely impact us | 
    
      | Future litigation may materially adversely impact us | 
    
      | Any future litigation may result in injunctions against future product sales     and  substantial  unanticipated  legal costs and divert the efforts of     management personnel, any and all of which could materially adversely impact     us | 
    
      | We may become subject to unfair hiring claims, which could prevent us from     hiring needed employees, incur liability for damages or incur substantial     unanticipated legal costs | 
    
      | Companies whose employees accept positions with competitors frequently claim     that these competitors have engaged in unfair hiring practices or that the     employment  of  these  persons  would involve the disclosure or use of     confidential information or trade secrets | 
    
      | These claims could prevent us     from hiring needed employees | 
    
      | They may result in us incurring liability for     damages and/or substantial unanticipated legal costs | 
    
      | These claims also may     divert the efforts of management personnel from our operations | 
    
      | Errors or defects in our products and services could expose us to liability     and harm our reputation | 
    
      | Our customers use our products and services in designing and developing     products that involve a high degree of technological complexity and have     unique specifications | 
    
      | Due to the complexity of the systems and products     with which we work, some of our products and designs can be adequately     tested  only when put to full use in the marketplace | 
    
      | As a result, our     customers or their end users may discover errors or defects in our software     or the systems we design, or the products or systems incorporating our     designs and intellectual property may not operate as expected | 
    
      | Errors or     defects could result in:           •   loss of current customers and loss of, or delay in, revenue and loss     of market share;           •   failure to attract new customers or achieve market acceptance;           •   diversion of development resources to resolve the problems resulting     from errors or defects; and           •   increased service costs | 
    
      | Our failure to attract and retain key employees may harm us | 
    
      | We  depend  on the efforts and abilities of our senior management, our     research and development staff and a number of other key management, sales,     support, technical and services personnel | 
    
      | Competition for experienced,     high-quality personnel is intense, and we cannot assure that we can continue     to recruit and retain such personnel | 
    
      | The failure by us to hire and retain     such personnel would impair our ability to develop new products and manage     our business effectively | 
    
      | Regulations adopted by the NASDAQ Stock Market require stockholder approval     for new stock option plans and significant amendments to existing plans,     including  increasing the number of options available for grant | 
    
      | These     regulations could make it more difficult for us to grant equity compensation     to employees in the future | 
    
      | To the extent that these regulations make it     more difficult or expensive to grant equity compensation to employees, we     may incur increased compensation costs or find it difficult to attract and     retain employees, which could materially adversely impact us | 
    
      | Terrorist attacks and other acts of violence or war may materially adversely     impact the markets on which our securities trade, the markets in which we     operate, our operations and our profitability | 
    
      | Terrorist attacks may negatively affect our operations and investment in our     business | 
    
      | These attacks or armed conflicts may directly impact our physical     facilities  or those of our suppliers or customers | 
    
      | Furthermore, these     attacks may make travel more difficult and expensive and ultimately affect     our revenues | 
    
      | Any armed conflict entered into by the United States could have an adverse     impact on our revenues and our ability to deliver products to our customers | 
    
      | Political and economic instability in some regions of the world may also     result from an armed conflict and could negatively impact our business | 
    
      | We     currently have operations in Pakistan, Egypt and Israel, countries that may     be particularly susceptible to this risk | 
    
      | The consequences of any armed     conflict are unpredictable, and we may not be able to foresee events that     could have an adverse impact on us | 
    
      | 11     ______________________________________________________________________    [36]Table of Contents       More generally, any of these events could cause consumer confidence and     spending to decrease or result in increased volatility in the United States     and worldwide financial markets and economy | 
    
      | They also could result in     economic recession in the United States or abroad | 
    
      | Any of these occurrences     could have a significant impact on our operating results, revenues and costs     and may result in volatility of the market price for our common stock | 
    
      | Our articles of incorporation, Oregon law and our shareholder rights plan     may have anti-takeover effects | 
    
      | Our  board  of  directors  has  the  authority,  without action by the     shareholders, to designate and issue up to 1cmam200cmam000 shares of incentive     stock in one or more series and to designate the rights, preferences and     privileges  of  each  series without any further vote or action by the     shareholders | 
    
      | Additionally, the Oregon Control Share Act and the Business     Combination Act limit the ability of parties who acquire a significant     amount of voting stock to exercise control over us | 
    
      | These provisions may     have the effect of lengthening the time required for a person to acquire     control of us through a proxy contest or the election of a majority of the     board of directors | 
    
      | In February 1999, we adopted a shareholder rights plan,     which has the effect of making it more difficult for a person to acquire     control of us in a transaction not approved by our board of directors | 
    
      | The     potential issuance of incentive stock, the provisions of the Oregon Control     Share Act and the Business Combination Act and our shareholder rights plan     may have the effect of delaying, deferring or preventing a change of control     of us, may discourage bids for our common stock at a premium over the market     price of our common stock and may materially adversely impact the market     price of, and the voting and other rights of the holders of, our common     stock | 
    
      | Our debt obligations expose us to risks that could materially adversely     impact our business, operating results and financial condition, and could     prevent us from fulfilling our obligations under such indebtedness | 
    
      | We have a substantial level of indebtedness | 
    
      | As of December 31, 2005, we had     dlra294dtta0 million of outstanding indebtedness, which includes dlra171dtta5 million of     6 7/8prca Convertible Subordinated Notes (Notes) due 2007 and dlra110dtta0 million of     Floating Rate Convertible Subordinated Debentures (Debentures) due 2023 | 
    
      | This level of indebtedness among other things, could:           •   make it difficult for us to satisfy our payment obligations on our     debt;           •   make it difficult for us to incur additional indebtedness or obtain     any necessary financing in the future for working capital, capital     expenditures, debt service, acquisitions or general corporate purposes;           •   limit our flexibility in planning for or reacting to changes in our     business;           •   reduce funds available for use in our operations;           •   make us more vulnerable in the event of a downturn in our business;           •   make us more vulnerable in the event of an increase in interest rates     if we must incur new debt to satisfy our obligations under the Notes and     Debentures; or           •   place us at a possible competitive disadvantage relative to less     leveraged competitors and competitors that have greater access to capital     resources | 
    
      | If we experience a decline in revenues due to any of the factors described     in Item 1A “Risk Factors,” we could have difficulty paying amounts due on     our indebtedness | 
    
      | Any default under our indebtedness could have a material     adverse impact on our business, operating results and financial condition |
