Notes to Unaudited Condensed Consolidated Financial Statements

All numerical references in thousands, except percentages, per share data, and number of employees



|(1) | GeneralThe accompanying unaudited condensed consolidated financial statements have been prepared in conformity with United States (U.S.) generally accepted
accounting principles and reflect all material normal recurring adjustments. However, certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. generally accepted accounting
principles have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). In the opinion of management, the condensed consolidated financial statements include adjustments necessary for a fair
presentation of the results of the interim periods presented. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K
for the fiscal year ended January 31, 2009.

The preparation of condensed consolidated financial statements in conformity
with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and contingencies as of the date of the financial statements, and the reported amounts
of revenue and expenses during the reporting periods. As future events and their effects cannot be determined with precision, actual results could differ from these estimates. Changes in estimates resulting from continuing changes in the economic
environment will be reflected in the financial statements in future periods.



|(2) | Summary of Significant Accounting Policies
|--- | ------------------------------------------

Principles of Consolidation

The condensed consolidated financial statements include the financial statements of us and our
wholly-owned subsidiaries. All intercompany accounts and transactions were eliminated in consolidation.

We do not have off-balance sheet
arrangements, financings, or other similar relationships with unconsolidated entities or other persons, also known as special purpose entities. In the ordinary course of business, we lease certain real properties, primarily field sales offices,
research and development facilities, and equipment, as described in Note 10. Commitments and Contingencies.

Revenue
Recognition

We report revenue in two categories based upon how the revenue is generated: (i) system and software and
(ii) service and support.

System and software revenues  We derive system and software revenues from the sale of licenses
of software products, emulation hardware systems, and finance fee revenues from our long-term installment receivables resulting from product sales. We primarily license our products using two different license types:

1. Term licenses  We use this license type primarily for software sales. This license type provides the customer with the right to use a fixed list
of software products for a specified time period, typically three years, with payments spread over the license term, and does not provide the customer with the right to use the products after the end of the term. Term license arrangements may allow
the customer to share products between multiple locations and remix product usage from the fixed list of products at regular intervals during the license term. We generally recognize product revenue from term license arrangements upon product
delivery and start of the license term. In a term license agreement where we provide the customer with rights to unspecified or unreleased future products, we recognize revenue ratably over the license term. Revenue from emulation product sales
where the software is incidental to the hardware is generally recognized upon delivery.

2. Perpetual licenses  We use this license
type for software and emulation hardware system sales. This license type provides the customer with the right to use the product in perpetuity and typically does not provide for extended payment terms. We generally recognize product revenue from
perpetual license arrangements upon product delivery assuming all other criteria for revenue recognition have been met.

We include finance
fee revenues from the accretion on the discount of long-term installment receivables in System and software revenues. Finance fee revenues were $4,022 for the three months ended April 30, 2009 and $4,671 for the three months ended
April 30, 2008.

Service and support revenues  We derive service and support revenues from software and hardware
post-contract maintenance or support services and professional services, which include consulting, training, and other services. We recognize revenue ratably over the support services term. We record professional service revenue as the services are
provided to the customer.

We apply the provisions of Statement of Position (SOP) 97-2, Software Revenue Recognition, as
amended by SOP 98-9, Modification of SOP 97-2, Software Revenue Recognition, With Respect to Certain Transactions, to all software and hardware product revenue transactions where the software is not incidental. We determine whether
product revenue recognition is appropriate based upon the evaluation of whether the following four criteria have been met:

1. Persuasive
evidence of an arrangement exists  Generally, we use either a customer signed contract or qualified customer purchase order as evidence of an arrangement for both term and perpetual licenses. For professional service engagements, we generally
use a signed professional services agreement and a statement of work to evidence an arrangement. Sales through our distributors are evidenced by an agreement governing the relationship, together with binding purchase orders from the distributor on a
transaction-by-transaction basis.

2. Delivery has occurred  We generally deliver software and the corresponding access keys to
customers electronically. Electronic delivery occurs when we provide the customer access to the software. We may also deliver the software on a compact disc. Our software license agreements generally do not contain conditions for acceptance. With
respect to emulation hardware, we transfer title to the customer upon shipment. We offer non-essential installation services for emulation hardware sales or the customer may elect to perform the installation without assistance from us. Our emulation
hardware system agreements generally do not contain conditions for acceptance.

3. Fee is fixed or determinable  We assess whether a
fee is fixed or determinable at the outset of the arrangement, primarily based on the payment terms associated with the transaction. We have established a history of collecting under the original contract with installment terms without providing
concessions on payments, products, or services. Additionally, for installment contracts, we determine that the fee is fixed or determinable if the arrangement has a payment schedule that is within the term of the licenses and the payments are
collected in equal or nearly equal installments, when evaluated on a cumulative basis. If the fee is not deemed to be fixed or determinable, we recognize revenue as payments become due and payable.

Significant judgment is involved in assessing whether a fee is fixed or determinable. We must also make these judgments when assessing whether a contract
amendment to a term arrangement (primarily in the context of a license extension or renewal) constitutes a concession. Our experience has been that we are able to determine whether a fee is fixed or determinable for term licenses. While we do not
expect that experience to change, if we no longer were to have a history of collecting under the original contract without providing concessions on term licenses, revenue from term licenses would be required to be recognized when payments under the
installment contract become due and payable. Such a change could have a material impact on our results of operations.

4. Collectability is
probable  To recognize revenue, we must judge collectability of the arrangement fees on a customer-by-customer basis pursuant to our credit review process. We typically sell to customers with whom there is a history of successful collection.
We evaluate the financial position and a customers ability to pay whenever an existing customer purchases new products, renews an existing arrangement, or requests an increase in credit terms. For certain industries for which our products are
not considered core to the industry or the industry is generally considered troubled, we impose higher credit standards. If we determine that collectability is not probable based upon our credit review process or the customers payment history,
we recognize revenue as payments are received.

Multiple element arrangements  For multiple element arrangements, vendor-specific
objective evidence of fair value (VSOE) must exist to allocate the total fee among all delivered and non-essential undelivered elements of the arrangement. If undelivered elements of the arrangement are essential to the functionality of the product,
we defer revenue until the essential elements are delivered. If VSOE does not exist for one or more non-essential undelivered elements, we defer revenue until such evidence does exist for the undelivered elements, or until all elements are
delivered, whichever is earlier. If VSOE of all non-essential undelivered elements exists but VSOE does not exist for one or more delivered elements, we recognize revenue using the residual method. Under the residual method, we defer revenue related
to the undelivered elements based upon VSOE and we recognize the remaining portion of the arrangement fee as revenue for the delivered elements, assuming all other criteria for revenue recognition have been met. If we could no longer establish VSOE
for non-essential undelivered elements of multiple element arrangements, we would defer revenue until all elements are delivered or VSOE is established for the undelivered elements, whichever is earlier.

We base our VSOE for certain product elements of an arrangement upon the pricing in comparable transactions when the element is sold separately. We
primarily base our VSOE for term and perpetual support services upon customer renewal history where the services are sold separately. We also base VSOE for professional services and installation services for emulation hardware systems upon the price
charged when the services are sold separately.

Other General Expense (Income), Net

The gain or loss on the sale of qualifying receivables to certain financing institutions on a non-recourse basis is recorded in Other general expense
(income), net, a component of Operating expenses. The gain or loss on the sale of long-term receivables consists of two components: (i) the difference between the gross balance of the receivables and the net proceeds received from the financing
institution, referred to as the discount on sold receivables, and (ii) interest income representing the unaccreted discount on the receivables, which is recognized once the receivables are sold.



|(3) | Changes in AccountingIn this 10-Q, we have included adjustments to the prior period Condensed Consolidated Statements of Operations and Cash Flows and Condensed
Consolidated Balance Sheet as of January 31, 2009 due to changes in the accounting for research and development credits and due to the adoption of Financial Accounting Standards Board (FASB) Staff Position (FSP) Accounting Principles Board
(APB) 14-1, Accounting for Convertible Debt Instruments That May be Settled in Cash upon Conversion (Including Partial Cash Settlement) (FSP APB 14-1).

Change in Accounting for Research and Development Credits

The French Finance Act for 2008 (the FFA) was created to increase foreign investment and improve the business environment in France. The FFA included several changes to the research credit program, two of which were
changes to the method used to calculate the research credit and the amounts available for credit. The research credit is for certain research costs incurred in France and can be applied against current income tax liabilities due in France for a
period of three years. Alternatively, the credit can be refunded by the tax authority three years after being filed in a tax declaration if the company is in a tax loss situation.

Prior to the second quarter of fiscal 2009, we accounted for the research and development credits as an income tax credit which resulted in the treatment
of the credit as reduction of income tax expense. For our interim tax calculations this resulted in the credit impacting our overall annual effective tax rate applied to the quarterly periods. However, the research credit can be recovered
irrespective of whether we pay income taxes in France and can be predictably determined as research expenditures are incurred. Effective in the second quarter of fiscal 2009, we changed the accounting treatment of the research credit to account for
it as a subsidy from the government versus an income tax credit and recorded the credits as a reduction of research and development costs. We have determined that the credits are earned as the qualifying research expenditures are made.

In accordance with Statement of Financial Accounting Standards (SFAS) No. 154, Accounting Changes and Error Corrections, the change in
accounting principle is reported through retrospective application to all prior periods. Due to the methodology used to allocate intra-period income tax expense to each quarter, there are changes to Research and development expense, Total operating
expense, Operating loss, Loss before income tax, Income tax benefit, Net loss, and Net loss per share for the three months ended April 30, 2008 as illustrated in the table below. However, there was no impact to the previously reported annual
amounts of net loss, net loss per share, or accumulated deficit.

Adoption of FSP APB 14-1

During the three months ended April 30, 2009, we adopted the provisions of FSP APB 14-1, which requires that issuers of convertible debt instruments
that may be settled in cash upon conversion (including partial cash settlement) separately account for the implied liability and equity components of the convertible debt in a manner that reflects the entitys nonconvertible debt borrowing rate
when interest cost is recognized in subsequent periods. FSP APB 14-1 applies to the 6.25% Convertible Subordinated Debentures (6.25% Debentures) due 2026. Prior to the adoption of FSP APB 14-1, we carried the liability of the 6.25% Debentures at its
principal value and only the contractual interest expense was recognized in our Condensed Consolidated Statements of Operations. FSP APB 14-1 requires retrospective application to all prior periods for which the 6.25% Debentures were outstanding
prior to the date of adoption.

Upon adoption of FSP APB 14-1 and effective as of the issuance date of the 6.25% Debentures, we recorded
$23,976 of the principal amount to equity, representing a debt discount for the difference between our estimated nonconvertible debt borrowing rate of 8.6% at the time of issuance and the coupon rate of the 6.25% Debentures. This debt discount is
amortized as interest expense over the expected term using the effective interest method. In addition, we allocated $764 of the issuance costs to the equity component of the 6.25% Debentures and the remaining $5,606 of the issuance costs to the
liability component of the 6.25% Debentures. The issuance costs were allocated pro rata based on their initial carrying amounts.

The impact
of FSP APB 14-1 to Interest expense, Loss before income tax, Net loss, and Basic and diluted loss per share for the three months ended April 30, 2008 represent the amortization of the debt discount and adjustment of the previously recorded
amortization of the issuance costs. The adjustments to the Condensed Consolidated Balance Sheet as of January 31, 2009 reflect adjustments of:



| |  |  | Other assets and Prepaid expenses and other for the impact of the allocation of a portion of the issuance costs to equity;
| | - |  | --------------------------------------------------------------------------------------------------------------------------



| |  |  | Notes payable for the unamortized debt discount on the 6.25% Debentures;
| | - |  | ------------------------------------------------------------------------



| |  |  | Common stock for the recognition of the equity component of the 6.25% Debentures, net of a portion of the equity component that was retired upon repurchase of a
portion of the 6.25% Debentures; and

|(4) | Fair Value MeasurementOn a quarterly basis, we measure derivatives at fair value. SFAS No. 157, Fair Value Measurements (SFAS
157) established a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from

| | independent sources. Unobservable inputs reflect our market assumptions. SFAS 157 classifies these two types of inputs into the following fair-value
hierarchy:
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 1Quoted prices for identical instruments in active markets;
| | - |  | ------------------------------------------------------------------



| |  |  | Level 2Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and
model-derived valuations whose significant inputs are observable; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 3One or more significant inputs to the valuation model are unobservable.
| | - |  | -------------------------------------------------------------------------------

The following table presents information about financial assets required to be carried at fair value on a recurring basis as of April 30, 2009:



|                                              |  |                                |       |         |   |         |  |         |       |  |   |

We use an income approach to determine the fair value of our foreign currency forward and option
contracts. For foreign currency forward and option contracts designated as cash flow hedges, which are linked to a specific transaction, we report the net gains and losses in Accumulated other comprehensive income in Stockholders equity until
the forecasted transaction occurs or the hedge is no longer effective. Once the forecasted transaction occurs or the hedge is no longer effective, we reclassify the gains or losses attributable to the foreign currency forward and option contracts to
our Condensed Consolidated Statement of Operations. For foreign currency forward and option contracts entered into to offset the variability in exchange rates on certain short-term monetary assets and liabilities, we recognize changes in fair value
currently in Other income, net, in our Condensed Consolidated Statement of Operations. See further discussion in Note 7. Derivative Instruments and Hedging Activities.



|(5) | Business CombinationsFor many of our acquisitions, payment of a portion of the purchase price is contingent upon the acquired business achievement of
certain revenue and product performance goals. For business combinations completed prior to our adoption of SFAS 141(R) Business Combinations on February 1, 2009, these contingent payments, or earn-outs, are accrued when the
performance goals are met and the contingent consideration is issued or issuable. During the three months ended April 30, 2009, we recorded earn-outs of $810 based on related revenues derived from products and technologies acquired in prior
acquisitions compared to $571 during the three months ended April 30, 2008. During the three months ended April 30, 2009, we made earn-out payments of $2,043 compared to $1,909 during the three months ended April 30, 2008.

|(6) | Long-Term InvestmentsAs of April 30, 2009, we controlled 28.4% of the voting stock of Calypto Design Systems, Inc. (Calypto), an electronic design
automation (EDA) company, and 20% of the participating membership of the board of directors as a result of our investment in $2,000 of Series D Preferred Stock of Calypto. We have determined our investment in Calypto to be in-substance common
stock as described in Emerging Issues Task Force Issue No. 02-14, Whether an Investor Should Apply the Equity Method of Accounting to Investments Other Than Common Stock. Accordingly, we have accounted for our investment in
Calypto pursuant to the equity method of accounting in accordance with APB Opinion No. 18, The Equity Method of Accounting for Certain Investments in Debt and Equity Securities. We record our interest in the equity method gains or
losses of Calypto in the subsequent quarter following incurrence because it is not practical to obtain Calyptos financial statements prior to the issuance of our consolidated financial statements. During the three months ended April 30,
2009, we recorded a loss of $324 for our equity in the losses of Calypto for the three months ended January 31, 2009. During the three months ended April 30, 2008, we recorded a loss of $168 for our equity in the losses of Calypto for the
one month period ended January 31, 2008.

|(7) | Derivative Instruments and Hedging ActivitiesWe are exposed to fluctuations in foreign currency exchange rates. To manage the volatility, we aggregate exposures
on a consolidated basis to take advantage of natural offsets. The primary exposures that do not currently have natural offsets are the Japanese yen, where we are in a long position, and the euro and the British pound, where we are in a short
position. Most large European revenue contracts are denominated and paid to us in the U.S. dollar while our European expenses, including substantial research and development operations, are paid in local currencies causing a short position in the
euro and the British pound. In addition, we experience greater inflows than outflows of Japanese yen as almost all Japanese-based customers contract and pay us in Japanese yen. While these exposures are aggregated on a consolidated basis to take
advantage of natural offsets, substantial exposure remains.

##### Table of Contents

We generated nearly two-thirds of our revenues and approximately one-third of our expenses outside of the
U.S. for the three months ended April 30, 2009 and 2008. For the three months ended April 30, 2009, approximately one-third of European and all Japanese revenues were subject to exchange rate fluctuations as they were booked in local
currencies. For the three months ended April 30, 2008, approximately one-fourth of European and two-thirds of Japanese revenues were subject to exchange rate fluctuations.

For exposures that are not offset, we enter into short-term, not more than a year, foreign currency forward and option contracts to partially offset these
anticipated exposures. During the three months ended April 30, 2009, we entered into fifteen new foreign currency option contracts, with a total gross notional value of $81,492 and forty-one new foreign currency forward contracts, with a total gross
notional value of $178,126.

We formally document all relationships between foreign currency forward and option contracts and hedged items
as well as our risk management objectives and strategies for undertaking various hedge transactions. All hedges designated as cash flow hedges are linked to forecasted transactions and we assess, both at inception of the hedge and on an ongoing
basis, the effectiveness of the foreign currency forward and option contracts in offsetting changes in the cash flows of the hedged items. We report the effective portions of the net gains or losses on foreign currency forward and option contracts
as a component of Accumulated other comprehensive income in Stockholders equity. Accumulated other comprehensive income associated with hedges of forecasted transactions is reclassified to the Condensed Consolidated Statement of Operations in
the same period the forecasted transaction occurs. We discontinue hedge accounting prospectively when we determine that a foreign currency forward or option contract is not highly effective as a hedge under the requirements of SFAS No. 133,
Accounting for Derivative Instruments and Hedging Activities (SFAS 133). To the extent a forecasted transaction is no longer deemed probable of occurring, we prospectively discontinue hedge accounting treatment and we reclassify deferred
amounts to Other income, net in the Condensed Consolidated Statement of Operations. We noted no such instance in the three months ended April 30, 2009 or 2008.

Effective February 1, 2009, we adopted the disclosure requirement of SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities  an amendment to Statement No. 133
(SFAS 161). In accordance with SFAS 161, the fair values and balance sheet presentation of our derivatives instruments as of April 30, 2009 are summarized as follows:

We had foreign currency forward and option contracts outstanding with a gross notional value of
$392,445 as of April 30, 2009. Notional amounts do not quantify risk or represent our assets or liabilities but are used in the calculation of cash settlements under the contracts.

By using derivative instruments, we subject ourselves to credit risk. If a counterparty fails to fulfill its performance obligations under a derivative
contract, our credit risk will equal the fair value of the derivative instrument. Generally, when the fair value of our derivative contracts is in a net asset position, the counterparty owes us, thus creating a receivable risk for us. We minimize
counterparty credit risk by entering into derivative transactions with major financial institutions, as such we do not expect material losses as a result of default by our counterparties.

Included in the gain of $97 recognized in Other income, net of cash flow forwards, a gain of $94
was related to the time value exclusion of foreign currency forward contracts from our assessment of hedge effectiveness.

The hedge balance
in Accumulated other comprehensive income as of April 30, 2009 of $92, after tax effect, represents a net unrealized gain on foreign currency forward and option contracts related to hedges of forecasted revenues and expenses expected to occur
during fiscal 2010. We will transfer these amounts to the Condensed Consolidated Statement of Operations upon recognition of the related revenues and recording of the respective expenses. We expect substantially all of the hedge balance in
Accumulated other comprehensive income to be reclassified to the Condensed Consolidated Statement of Operations within the next twelve months.

We enter into foreign currency contracts to offset the earnings impact relating to the variability in exchange rates on certain short-term monetary assets and liabilities denominated in non-functional currencies. We do not designate these
foreign currency contracts as hedges. In accordance with SFAS 161, the effect of derivative instruments not designated as hedging instruments on income for the three months ended April 30, 2009 is as follows:

|(8) | Short-Term BorrowingsIn June 2005, we entered into a syndicated, senior, unsecured, four-year revolving credit facility that replaced an existing three-year
revolving credit facility. In April 2008, we extended this revolving credit facility by two years until June 1, 2011. In May 2008, we increased the maximum borrowing capacity from $120,000 to $140,000 and retained an option to increase it by an
additional $10,000 in the future. In March 2009, we amended the revolving credit facility to reduce the minimum tangible net worth calculated as of January 31, 2009, which is used as the starting point for future calculations, by $15,000, and
to make certain other changes reflected in the discussion below. Under this revolving credit facility, we have the option to pay interest based on: (i) London Interbank Offered Rate (LIBOR) with varying maturities which are commensurate with
the borrowing period we select, plus a spread of between 1.0% and 1.6%, or (ii) a base rate plus a spread of between 0.0% and 0.6%, based on a pricing grid tied to a financial covenant. The base rate is defined as the higher of: (i) the
federal funds rate, as defined, plus 0.5%, (ii) the prime rate of the lead bank, or (iii) one-month LIBOR plus 1.0%. As a result, our interest expense associated with borrowings under this revolving credit facility will vary with market
interest rates. In addition, commitment fees are payable on the unused portion of the revolving credit facility at rates between 0.25% and 0.35% based on a pricing grid tied to a financial covenant. We paid commitment fees of $77 for the three
months ended April 30, 2009 compared to $75 for the three months ended April 30, 2008. This revolving credit facility contains certain financial and other covenants, including the following:

be less than 0.85;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our tangible net worth (stockholders equity less goodwill and other intangible assets) must exceed the calculated required tangible net worth as defined in
the credit agreement, which establishes a fixed level of required tangible net worth, and then increases that required level each quarter by 70% of any positive net income in the quarter (but in the aggregate no more than 70% of positive net income
for any full fiscal year), 100% of the amortization of intangible assets in the quarter, and 100% of certain stock issuance proceeds, which increases are offset by certain amounts of acquired intangible assets;

The revolving credit facility prevents us from
paying dividends.

We were in compliance with all financial covenants as of April 30, 2009. If we were to fail to comply with the
financial covenants and did not obtain a waiver from our lenders, we would be in default under the revolving credit facility and our lenders could terminate the facility and demand immediate repayment of all outstanding loans under the revolving
credit facility.

We did not borrow any amounts under the revolving credit facility during the three months ended April 30, 2009 or
April 30, 2008. As of April 30, 2009 and January 31, 2009, we had an outstanding balance under the facility of $20,000. The interest rate was 3.85% as of April 30, 2009 and 3.25% as of January 31, 2009.

Short-term borrowings of $5,614 as of April 30, 2009 and $12,550 as of January 31, 2009 represent amounts collected from customers on accounts
receivable previously sold on a non-recourse basis to financial institutions. These amounts are remitted to the financial institutions during the quarter following the period end.

We generally have other short-term borrowings, including multi-currency lines of credit and other borrowings. Interest rates are generally based on the
applicable countrys prime lending rate, depending on the currency borrowed. Other short-term borrowings outstanding under these facilities were $4,124 as of April 30, 2009 and $4,448 as of January 31, 2009.

6.25% Debentures due 2026: In March 2006, we issued $200,000 of 6.25% Debentures in a
private offering pursuant to SEC Rule 144A under the Securities Act of 1933. Interest on the 6.25% Debentures is payable semi-annually in March and September. The 6.25% Debentures are convertible, under certain circumstances, into our common stock
at a conversion price of $17.968 per share for a total of 9,183 shares as of April 30, 2009. These circumstances generally include:



| |  |  | The market price of our common stock exceeding 120% of the conversion price;
| | - |  | ----------------------------------------------------------------------------



| |  |  | The market price of the 6.25% Debentures declining to less than 98% of the value of the common stock into which the 6.25% Debentures are convertible;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A call for the redemption of the 6.25% Debentures;
| | - |  | --------------------------------------------------



| |  |  | Specified distributions to holders of our common stock;
| | - |  | -------------------------------------------------------



| |  |  | If a fundamental change, such as a change of control, occurs; or
| | - |  | ----------------------------------------------------------------



| |  |  | During the ten trading days prior to, but not on, the maturity date.
| | - |  | --------------------------------------------------------------------

Upon conversion, in lieu of shares of our common stock, for each $1 principal amount of the 6.25% Debentures a holder will receive an amount of cash equal to the lesser of: (i) $1 or (ii) the conversion
value of the number of shares of our common stock equal to the conversion rate. If such conversion value exceeds $1, we will also deliver, at our election, cash or common stock, or a combination of cash and common stock with a value equal to the
excess. If a holder elects to convert their 6.25% Debentures in connection with a fundamental change in the company that occurs prior to March 6, 2011, the holder will also be entitled to receive a make whole premium upon conversion in some
circumstances. The 6.25% Debentures rank pari passu with the Floating Rate Convertible Subordinated Debentures (Floating Rate Debentures) due 2023. We may redeem some or all of the 6.25% Debentures for cash on or after March 6, 2011. The
holders, at their option, may redeem some or all of the 6.25% Debentures for cash on March 1, 2013, 2016, or 2021. During the three months ended April 30, 2009, we did not repurchase any 6.25% Debentures and the principal amount of
$165,000 remains outstanding.

During the three months ended April 30, 2009, we adopted FSP APB 14-1, which specifies that issuers
of convertible debt that may be settled in cash upon conversion (including partial cash settlement) separately account for the implied liability and equity components of the convertible debt in a manner that reflects the issuers nonconvertible
debt borrowing rate when interest cost is recognized in subsequent periods. FSP APB 14-1 applies to our 6.25% Debentures. FSP APB 14-1 requires retrospective application to all periods. The impact of adopting FSP APB 14-1 is further described in
Note 3. Changes in Accounting.

The principal amount, unamortized debt discount and net carrying amount of the liability
component as well as the carrying amount of the equity component of the 6.25% Debentures are as follows:

The remaining unamortized debt discount will be amortized to interest expense using the effective
interest method through March 2013.

We recognized the following amounts in interest expense in the Condensed Consolidated Statements of
Operations related to the 6.25% Debentures:



|                                                  |  |                              |       |      |   |

The effective interest rate on the 6.25% Debentures was 8.6% for both the three months ended
April 30, 2009 and 2008.

Floating Rate Debentures due 2023: In August 2003, we issued $110,000 of Floating Rate Debentures in a
private offering pursuant to SEC Rule 144A under the Securities Act of 1933. Interest on the Floating Rate Debentures is payable quarterly in February, May, August, and November at a variable interest rate equal to 3-month LIBOR plus 1.65%. The
effective interest rate was 2.97% for the three months ended April 30, 2009 and 4.89% for the three months ended April 30, 2008. The Floating Rate Debentures are convertible, under certain circumstances, into our common stock at a
conversion price of $23.40 per share for a total of 1,443 shares as of April 30, 2009. These circumstances generally include:



| |  |  | The market price of our common stock exceeding 120% of the conversion price;
| | - |  | ----------------------------------------------------------------------------



| |  |  | The market price of the Floating Rate Debentures declining to less than 98% of the value of the common stock into which the Floating Rate Debentures are
convertible; or
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A call for redemption of the Floating Rate Debentures or certain other corporate transactions.
| | - |  | ----------------------------------------------------------------------------------------------

The conversion price may also be adjusted based on certain future transactions, such as stock splits or stock dividends. Effective August 2008, we may
redeem some or all of the Floating Rate Debentures for cash at 101.61% of the face amount, with the premium reducing to 0.81% on August 6, 2009 and 0% on August 6, 2010. The holders, at their option, may redeem some or all of the Floating
Rate Debentures for cash on August 6, 2010, 2013, or 2018. During the three months ended April 30, 2009, we repurchased on the open market and retired Floating Rate Debentures with a principal balance of $2,330 for a total purchase price
of $2,066. As a result, a principal amount of $33,772 remains outstanding as of April 30, 2009. In connection with this purchase, during the three months ended April 30, 2009, we incurred a before tax net gain on the early extinguishment
of debt of $248, which included a $264 discount on the repurchased Floating Rate Debentures and a write-off of $16 of a portion of unamortized deferred debt issuance costs.

|(10) | Commitments and Contingencies
|---- | -----------------------------

Leases

We lease a majority of our field sales offices and research and development facilities under non-cancelable operating leases. In
addition, we lease certain equipment used in our research and development activities. This equipment is generally leased on a month-to-month basis after meeting a six-month lease minimum. There have been no significant changes to the future minimum
lease payments due under non-cancelable operating leases as disclosed in our Annual Report on Form 10-K for the fiscal year ended January 31, 2009.

Income Taxes

As of April 30, 2009, we had a liability of approximately $52,578 for income taxes
associated with uncertain income tax positions. All of these liabilities are classified as long-term liabilities in our Condensed Consolidated Balance Sheet, as we generally do not anticipate the settlement of the liabilities will require payment of
cash within the next twelve months. Further, certain liabilities may result in the reduction of deferred tax assets rather than settlement in cash. We are not able to reasonably estimate the timing of any cash payments required to settle these
liabilities and do not believe that the ultimate settlement of these obligations will materially affect our liquidity.

Contractual
Obligations

In conjunction with the acquisition of undeveloped 22 nanometer technology we acquired under a joint development agreement
entered into during the second quarter of fiscal 2009, we are required to make payments of $5,000 during fiscal 2010, and annual payments of $2,500 during each of fiscal 2011 through fiscal 2013. Of the $5,000 due in fiscal 2010, we paid $1,250
during the three months ended April 30, 2009.

Indemnifications

Our license and service agreements generally include a limited indemnification provision for claims from third parties relating to our intellectual
property. These indemnification provisions are accounted for in accordance with SFAS No. 5, Accounting for Contingencies (SFAS 5). The indemnification is generally limited to the amount paid by the customer or a set cap. As of
April 30, 2009, we were not aware of any material liabilities arising from these indemnifications.

Legal Proceedings

From time to time, we are involved in various disputes and litigation matters that arise from the ordinary course of business. These
include disputes and lawsuits relating to intellectual property rights, contracts, distributorships, and employee relations matters. Periodically, we review the status of various disputes and litigation matters and assess each potential exposure.
When we consider the potential loss from any dispute or legal matter probable and the amount or the range of loss can be estimated, we will accrue a liability for the estimated loss in accordance with SFAS 5. Legal proceedings are subject to
uncertainties and the outcomes are difficult to predict. Because of such uncertainties, we base accruals only on the best information available at the time. As additional information becomes available, we reassess the potential liability related to
pending claims and litigation matters and may revise estimates. We believe that the outcome of current litigation, individually and in the aggregate, will not have a material effect on our results of operations.



|(11) | Accounting for Stock-Based Compensation
|---- | ---------------------------------------

Stock Option Plans and Stock Plans

We have two common stock option plans which provide for the granting of incentive stock
options, nonqualified stock options (NQSOs), stock appreciation rights, restricted stock, restricted stock units, and performance-based awards. The two common stock option plans are administered by the Compensation Committee of our board of
directors and permit accelerated vesting of outstanding options upon the occurrence of certain changes in control of our company.

We also
have a stock plan that provides for the sale of common stock to our officers, key employees, and non-employee consultants. This plan allows for shares to be awarded at no purchase price as a stock bonus or with a purchase price as a NQSO.

Stock options under the above three plans generally expire ten years from the date of grant and become exercisable over four years from the
date of grant or from the commencement of employment, at prices generally not less than the fair market value at the date of grant.

The
1987 Non-Employee Directors Stock Plan provides for the annual grant to each non-employee director of either an option for 21 shares of common stock or 7 shares of restricted stock, each vesting over a period of five years but with accelerated
vesting upon any termination of service. During the three months ended April 30, 2009 and 2008, there were no restricted shares issued under this plan. Options granted under this plan are included in the table below.

##### Table of Contents

As of April 30, 2009, a total of 6,557 shares of common stock were available for future grant under
the above stock option and stock plans.

Stock options outstanding, the weighted average exercise price, and transactions involving the
stock option plans are summarized as follows:

Employee Stock Purchase Plans

We have an employee stock purchase plan (ESPP) for U.S. employees and an ESPP for certain foreign subsidiary employees. The ESPPs generally provide for
overlapping two-year offerings starting every six months on January 1 and July 1 of each year with purchases every six months during those offerings. Each eligible employee may purchase up to six thousand shares of stock on each purchase
date at prices no less than 85% of the lesser of the fair market value of the shares at the beginning of the two-year offering period or on the applicable purchase date. As of April 30, 2009, 5,537 shares remain available for future purchase
under the ESPPs.

Stock-Based Compensation Expense

We estimate the fair value of stock options and purchase rights under our ESPPs in accordance with SFAS No. 123 (revised 2004), Share-Based Payment, using a Black-Scholes option-pricing
model. The Black-Scholes option-pricing model incorporates several highly subjective assumptions including expected volatility, expected term, and interest rates. In reaching our determination of expected volatility for options, we include
the following elements:



| |  |  | Historical volatility of our shares of common stock;
| | - |  | ----------------------------------------------------



| |  |  | Historical volatility of shares of comparable companies;
| | - |  | --------------------------------------------------------



| |  |  | Implied volatility of the option features in our convertible subordinated debentures; and
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | Implied volatility of traded options of comparable companies.
| | - |  | -------------------------------------------------------------

In reaching our determination of expected volatility for purchase rights under our employee stock plan, we use the historical volatility of our shares of common stock.

We base the expected term of our stock options on historical experience. Using the Black-Scholes option-pricing model, the weighted average grant date
fair values are summarized as follows:



|                     |  |                              |      |      |   |

We issued 222 shares of common stock valued at $3,014 to the founders of a company we acquired in
June 2007. These shares are subject to forfeiture if their employment terminates prior to June 2009. The value of these shares is being amortized over a two year period.



|(12) | Net Loss Per ShareWe compute basic net loss per share using the weighted average number of common shares outstanding during the period. We compute diluted net
loss per share using the weighted average number of common shares and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares consist of common shares issuable upon exercise of employee stock options,
purchase rights from ESPPs, and warrants using the treasury stock method and common shares issuable upon conversion of the convertible subordinated debentures, if dilutive.

We excluded from the computation of diluted net loss per share options, warrants, and ESPP
purchase rights to purchase 21,777 shares of common stock for the three months ended April 30, 2009 and 19,572 for the three months ended April 30, 2008. The options, warrants, and ESPP purchase rights were anti-dilutive either because we
incurred a net loss for the period, the warrant price was greater than the average market price of the common stock during the period, or the option was determined to be anti-dilutive as a result of applying the treasury stock method in accordance
with SFAS No. 128, Earnings per Share (SFAS 128).

The effect of the conversion of the Floating Rate Debentures and the
6.25% Debentures was anti-dilutive and therefore excluded from the computation of diluted net loss per share. If the Floating Rate Debentures had been dilutive, our diluted net loss would have included additional earnings of $201 for the three
months ended April 30, 2009 and $304 for the three months ended April 30, 2008 and additional incremental common shares of 1,514 for the three months ended April 30, 2009 and 1,543 for the three months ended April 30, 2008. In
accordance with SFAS 128, we assume that the 6.25% Debentures will be settled in common stock for purposes of calculating the dilutive effect of the 6.25% Debentures. If the effect of the 6.25% Debentures had been dilutive, our diluted net loss
would have included additional earnings of $1,057 for the three months ended April 30, 2009 and 2008 and no additional incremental shares for the three months ended April 30, 2009 and 2008, as the stock price was below the conversion rate.
The conversion features of the 6.25% Debentures, which allow for settlement in cash, common stock, or a combination of cash and common stock, are further described in Note 9. Notes Payable.

Special charges primarily consisted of costs incurred for employee terminations and were due to
our reduction of personnel resources driven by modifications of business strategy or business emphasis.

We rebalanced our workforce by 150
employees during the three months ended April 30, 2009. The reduction impacted several employee groups. Employee severance costs of $4,028 included severance benefits, notice pay, and outplacement services. The total rebalance charge represents
the aggregate of numerous unrelated rebalance plans, none of which was individually material to our financial position or results of operations. We determined termination benefit amounts based on employee status, years of service, and local
statutory requirements. We communicated termination benefits to the affected employees prior to the end of the quarter in which we recorded the charge. Approximately 40% of these costs were paid during the three months ended April 30, 2009. We
expect to pay the remainder during fiscal 2010. There have been no significant modifications to the amount of these charges.

The reduction
of leased facility costs of $41 during the three months ended April 30, 2009 resulted from the buy out of a lease which had been previously abandoned.

Acquisition costs of $268 during the three months ended April, 30, 2009 represent legal and other costs related to a potential acquisition.

Other special charges for the three months ended April 30, 2009 included costs of $1,175 related to advisory fees and charges of $265 related to a casualty loss.

We rebalanced our workforce by 110 employees during the three months ended April 30, 2008. The reduction impacted several employee groups. Employee
severance costs of $8,114 included severance benefits, notice pay, and outplacement services. The total rebalance charge represents the aggregate of numerous unrelated rebalance plans, none of which was individually material to our financial
position or results of operations. We determined termination benefit amounts based on employee status, years of service, and local statutory requirements. We communicated termination benefits to the affected employees prior to the end of the quarter
in which we recorded the charge. The majority of these costs were paid during fiscal 2009. There have been no significant modifications to the amount of these charges.

Excess leased facility costs of $1,443 during the three months ended April 30, 2008 were primarily due to the abandonment of two additional leased facilities and a change in the estimate of sublease income of a
previously abandoned leased facility.

Other special charges for the three months ended April 30, 2008 included costs of $93 related to
the closure of a division.

|------- | -------------------------------------------------------------------------------------

All numerical references included in tables are in thousands, except percentages.

Overview

The following discussion should be read in conjunction with the condensed consolidated financial statements and notes included elsewhere in this
Form 10-Q. Certain of the statements below contain forward-looking statements. These statements are predictions based upon our current expectations about future trends and events. Actual results could vary materially as a result of certain factors,
including but not limited to, those expressed in these statements. In particular, we refer you to the risks discussed in Part II, Item 1A. Risk Factors and in our other Securities and Exchange Commission (SEC) filings, which
identify important risks and uncertainties that could cause our actual results to differ materially from those contained in the forward-looking statements.

We urge you to consider these factors carefully in evaluating the forward-looking statements contained in this Form 10-Q. All subsequent written or spoken forward-looking statements attributable to our company or persons acting on our
behalf are expressly qualified in their entirety by these cautionary statements. The forward-looking statements included in this Form 10-Q are made only as of the date of this Form 10-Q. We do not intend, and undertake no obligation, to update these
forward-looking statements.

The Company

We are
a supplier of electronic design automation (EDA) systems  advanced computer software and emulation systems used to automate the design, analysis, and testing of electronic hardware and embedded systems software in electronic systems and
components. We market our products and services worldwide, primarily to large companies in the military/aerospace, communications, computer, consumer electronics, semiconductor, networking, multimedia, and transportation industries. Through the
diversification of our customer base among these various customer markets, we attempt to reduce our exposure to fluctuations within each market. We sell and license our products through our direct sales force and a channel of distributors and sales
representatives. In addition to our corporate offices in Wilsonville, Oregon, we have sales, support, software development, and professional service offices worldwide.

We focus on products and design platforms where we have leading market share, thus enabling us to spend more effort to cause adoption of our technology in new applications, especially for new markets in which EDA
companies have not participated. We believe this strategy leads to a more diversified product and customer mix than many of our competitors, can help and reduce volatility of business, credit risk, and competition, while increasing the potential for
growth. System customers make up a much larger percentage of our business than that of most of our EDA competitors.

We derive system and software revenues
primarily from the sale of term software license contracts, which are typically three to four years in length. We generally recognize revenue for these arrangements upon product delivery at the beginning of the license term. Larger enterprise-wide
customer contracts, which in the aggregate can represent as much or more than 50% of our system and software revenue, drive the majority of our period-to-period revenue variances. Some of these contracts include unlimited or nearly unlimited access
to a fixed group of products. For these reasons, the timing, size, and success of contract renewals is the primary driver of revenue changes from period to period and to a lesser extent new contracts or an increase in the capacity of existing
contracts.

The EDA industry is highly competitive and is characterized by very strong leadership positions in specific segments of the EDA market. These
strong leadership positions can be maintained for significant periods of time as the software can be 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 leader. We will continue our strategy of developing high quality tools with number one market share potential,
rather than being a broad-line supplier with undifferentiated product offerings. This strategy allows us to focus investment in areas where customer needs are greatest and we have the opportunity to build significant market share.

Our products and services are dependent to a large degree on new design projects initiated by customers in the integrated circuit and electronics system industries.
These industries can be 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. Furthermore,
extended economic downturns can result in reduced funding for development due to downsizing and other business restructurings. These pressures are offset by the need for the development and introduction of next generation products once an economic
recovery occurs.

Our revenue has historically fluctuated quarterly and has generally been the highest in the fourth quarter of our fiscal year due to our
customers corporate calendar year-end spending trends and the timing of contract renewals.

Known Trends and Uncertainties Impacting Future Results of Operations

Business Trends

In the United States (U.S.) and abroad, recent market
and economic conditions have been unprecedented in the recent past and challenging, with tighter credit conditions, increased market volatility, diminished expectations for the U.S. and global economies, and increased market uncertainty and
instability in both U.S. and international capital and credit markets. These conditions, combined with generally declining business and consumer confidence and increased unemployment, have contributed to volatility of unprecedented levels.

As a result of these market conditions, the cost and availability of credit has been and may continue to be adversely affected by illiquid credit markets
and wider credit spreads. Many lenders and institutional investors reduced, and in some cases, ceased to provide, funding to borrowers due to the absence of a securitization market and concerns about the stability of the markets generally and the
strength of the counterparties specifically. Continued turbulence in the U.S. and international markets and economies may adversely affect our liquidity and financial condition, and the liquidity and financial condition of our customers. If these
market conditions continue, they may limit our ability, and the ability of our customers, to access the capital markets to meet liquidity needs and timely refinance maturing liabilities, resulting in an adverse effect on our financial condition and
results of operations.

The semiconductor industry experienced a bounce back from the major reductions in supply chain inventories in the fourth quarter of
fiscal 2009, with foundries reporting a recovery in loadings. However, bankruptcies and credit problems are increasingly evident and had an effect on our revenues during the first quarter of fiscal 2010.

The semiconductor industry is particularly vulnerable in this economy as several of the largest companies lack the balance sheet strength that they historically carried
into recessions. Consistent with our revenue recognition policy, when individual customer credit worthiness declines to a level where we do not consider collectability probable, we convert new transactions from up-front revenue recognition to
cash-based revenue recognition and we may be required to modify the payment terms to meet the customers ability to pay. Our top ten accounts make up approximately 40% of our receivables, including both short and long term balances, and we have
not experienced and do not presently expect collection issues with these customers. Net of reserves, we have no receivables greater than 60 days past due, and continue to experience no difficulty in factoring our receivables.

Bad debt expense recorded for the first quarter of fiscal 2010 was not material. However, we do have exposures within our receivables portfolio to some of the larger
semiconductor companies with weak credit ratings. These receivables balances do not represent a material portion of our portfolio but could have a material effect on earnings in any given quarter, should additional allowances for doubtful accounts
be necessary.

We rely on smaller dollar contracts for a material portion of our business. During fiscal 2009 we experienced a decline in these
transactions, which we believe contributed to a decline in our revenue for fiscal 2009. For the first quarter of fiscal 2010 we continued to see a reduced contribution from these accounts and the timing of recovery is not known.

We noted a decline in service and support revenues in the first quarter of fiscal 2010. A multi-quarter increase or decrease in service and support revenue can be an
early indicator that our business is either strengthening or weakening. Our experience is that customers will scale back on the purchase of outsourcing services in times of economic decline or weakness.

Bookings during the first three months of fiscal 2010 improved by 25% compared to the first three months of fiscal 2009. Bookings are the value of executed orders during
a period for which revenue has been or will be recognized within six months for products and within twelve months for professional services and training. The ten largest transactions for the three months ended April 30, 2009 accounted for
approximately 60% of total system and software bookings compared to 45% for the three months ended April 30, 2008. The number of new customers during the three months ended April 30, 2009, excluding PADS (our ready to use printed circuit
board design tools) and new customer relationships arising out of our acquisition of Flomerics Group Plc. (Flomerics) was down 55% from the levels experienced during the three months ended April 30, 2008.

Product Developments

During the three months ended
April 30, 2009, we continued to execute our strategy of focusing on challenges encountered by customers, as well as building upon our well-established product families. We believe that customers, faced with leading-edge design challenges in
creating new products, generally choose the best EDA products in each category to build their design environment. Through both internal development and strategic acquisitions, we have focused on areas where we believe we can build a leading market
position or extend an existing leading market position.

##### Table of Contents

We believe that the development and commercialization of EDA software tools is generally a three to five year process
with limited customer adoption and sales in the first years of tool availability. Once tools are adopted, however, their life spans tend to be long. We introduced new products and upgrades to existing products in the first quarter of 2010 that we
believe have the potential for widespread customer adoption and may have a favorable impact on future periods. During the three months ended April 30, 2009, we did not have any significant products reaching the end of their useful economic
life.

Critical Accounting Policies

We base our
discussion and analysis of our financial condition and results of operations upon our condensed consolidated financial statements which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these
financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, and contingencies as of the date of the financial statements and the reported amounts of revenues and expenses during the
reporting periods. We evaluate our estimates on an on-going basis. We base our estimates on historical experience, current facts, and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form
the basis for making judgments about the carrying values of assets and liabilities and the recording of revenue, costs, and expenses that are not readily apparent from other sources. As future events and their effects cannot be determined with
precision, actual results could differ from those estimates.

We believe that the accounting for revenue recognition, valuation of trade accounts
receivable, valuation of deferred tax assets, income tax reserves, goodwill, intangible assets and long-lived assets, special charges, and accounting for stock-based compensation are the critical accounting estimates and judgments used in the
preparation of our condensed consolidated financial statements. For a discussion of our critical accounting policies, see Item 7. Managements Discussion and Analysis of Financial Condition and Results of Operations  Critical
Accounting Policies in our Annual Report on Form 10-K for the year ended January 31, 2009.

We derive system and software revenues from the sale of licenses of software products, emulation hardware systems,
and finance fee revenues from our long-term installment receivables resulting from product sales. Upfront license revenues are comprised of perpetual licenses and term licenses for which we recognize revenue upon product delivery at the start of the
license term. Ratable license revenues are comprised of term licenses where we provide the customer with rights to unspecified or unreleased future products and as a result, recognize revenue ratably over the license term. Finance fee revenues are
from the accretion on the discount of long-term installment receivables.

For the three months ended April 30, 2009, our top ten customers accounted for approximately $77.0 million, or 67%,
of total System and software revenues compared to approximately $52.0 million, or 54%, for the three months ended April 30, 2008. For the three months ended April 30, 2009, one customer accounted for 13% and another customer accounted for
12% of our total revenues. No single customer accounted for 10% or more of total revenues for the three months ended April 30, 2008. Sales of product associated with our acquisition of Flomerics Group, PLC (Flomerics) in the second quarter of
fiscal 2009 resulted in an increase of approximately $4.0 million in System and software revenues during the three months ended April 30, 2009 compared to the three months ended April 30, 2008. Foreign currency had a slightly negative
impact on revenues for the first quarter of fiscal 2010 compared to the first quarter of fiscal 2009 as a result of a weakening of the euro and British pound against the U.S. dollar for the comparative periods of $2.0 million.

System and software gross margin percentage increased for the three months ended April 30, 2009 compared to the three months ended April 30, 2008 primarily due
to increased System and software revenues of $18.6 million.

Amortization of purchased technology to System and software cost of revenues was $2.9 million
for the three months ended April 30, 2009 compared to $3.2 million for the three months ended April 30, 2008. We amortize purchased technology costs over two to five years. The decrease in amortization for the three months ended
April 30, 2009 was primarily due to the accelerated full amortization of certain purchased technology of $1.4 million due to the closure of our intellectual property division in the three months ended April 30, 2008, offset by an increase
in amortization of $1.5 million resulting from technology acquired in the Flomerics acquisition in the second quarter of fiscal 2009.

Service and
Support

We derive service and support revenues from software and hardware post-contract maintenance or support services and professional services,
which include consulting, training, and other services. Service and support revenues decreased for the three months ended April 30, 2009 compared to the three months ended April 30, 2008 primarily due to declines in support revenues of
approximately $4.0 million and professional service revenues of approximately $3.0 million. The decrease in revenues is primarily the result of the softening of the global economy as our customers scale back on purchases of outsourced services.
These decreases were offset in part by approximately $3.0 million in Service and support revenues associated with our acquisition of Flomerics in the second quarter of fiscal 2009.

Service and support gross margin percentage increased for the three months ended April 30, 2009 compared to the three months ended April 30, 2008 primarily because of favorable foreign currency movements on
costs of $1.2 million, reductions in headcount related costs of $1.4 million, and reductions in outside service costs of $0.9 million. These improvements to costs were offset by the impact of lower revenues of $4.0 million.

Revenues increased in North America for the three months ended April 30, 2009 compared to the three months
ended April 30, 2008 primarily due to increased software product revenues of approximately $6.7 million, partially offset by a decrease in support and professional service revenues of approximately $3.0 million. The Flomerics acquisition
accounted for approximately $3.0 million of the North America revenue increase.

Revenues outside of North America represented 62% of total revenues for
the three months ended April 30, 2009 compared to 60% for the three months ended April 30, 2008. For the three months ended April 30, 2009, approximately one-third of European revenues were booked in local currencies and subject to
exchange rate fluctuations compared to approximately one-fourth of European revenues for the three months ended April 30, 2008. All other European revenue contracts are denominated and paid to us in U.S. dollars. Decreased European revenues for
the three months ended April 30, 2009 compared to the three months ended April 30, 2008 were primarily due to decreased software product revenues of approximately $8.0 million and unfavorable currency effects of approximately $2.0 million.
The Flomerics acquisition reduced the overall European revenue decline by approximately $3.0 million.

##### Table of Contents

All of our Japan revenues were recorded in Japanese yen during the three months ended April 30, 2009 compared to
approximately two-thirds of our Japan revenues during the three months ended April 30, 2008. The effects of exchange rate differences from the Japanese yen to the U.S. dollar favorably impacted Japanese revenues by approximately 6% for the
three months ended April 30, 2009 compared to the three months ended April 30, 2008. Exclusive of currency effects, lower revenues in Japan for the three months ended April 30, 2009 compared to the three months ended April 30,
2008 were primarily due to decreased support, training, and consulting revenues of approximately $1.2 million.

Revenues increased in the Pacific Rim for
the three months ended April 30, 2009 compared to the three months ended April 30, 2008 primarily due to increased software product revenues of approximately $21.0 million primarily due to a large term license transaction which shipped in
the first quarter of fiscal 2010.

Revenues associated with our acquisition of Flomerics in the second quarter of fiscal 2009 were not material in Japan
and the Pacific Rim.

We generate more than half of our revenues outside of North America and expect this to continue in the future. Revenue results will
continue to be impacted by future foreign currency fluctuations.

We incur a substantial portion of our operating expenses outside the United States in various foreign currencies.
When these currencies weaken against the U.S. dollar, our operating expense performance improves and when these currencies strengthen our operating expense performance is adversely affected.

Research and Development

For the three months ended
April 30, 2009 compared to the three months ended April 30, 2008 we recorded approximately $2.0 million in expenses resulting from our acquisitions of Flomerics and Ponte Solutions, Inc. (Ponte) which occurred in the second quarter of
fiscal 2009. This increase in expenses was more than offset by favorable currency movements of approximately $4.1 million.

Marketing and Selling

For the three months ended April 30, 2009 compared to the three months ended April 30, 2008 we recorded approximately $4.5 million in
expenses resulting from our acquisition of Flomerics in the second quarter of fiscal 2009. This increase in expense was offset by favorable currency movements of approximately $4.4 million.

General and Administration

For the three months ended
April 30, 2009 compared to the three months ended April 30, 2008, general and administration costs were flat. Currency movements had a minimal impact on general and administration costs. General and administration costs decreased as a
percentage of revenue from 13% for the three months ended April 30, 2008 to 12% for the three months ended April 30, 2009. We were able to leverage our administrative costs over a larger revenue base in the current fiscal year, which
included the Flomerics operations.

Other General Expense (Income), Net

Other general expense (income), net represents the expense (loss) or income (gain) on the sale of qualifying receivables to certain financing institutions on a non-recourse basis. The increase in expense from the
three months ended April 30, 2008 to the three months ended April 30, 2009 was primarily due to a decrease in the amount of receivables sold.

Amortization of Intangible Assets

For the three months ended April 30, 2009 compared to the three months ended April 30, 2008, the increase in amortization of intangible assets was primarily due to amortization of certain intangible assets
acquired in the Flomerics acquisition during the second quarter of fiscal 2009 of approximately $0.5 million.

Exclusive of future acquisitions,
amortization of intangible assets will decrease in fiscal 2010 primarily due to the complete amortization of intangible assets related to prior technology acquisitions partially offset by a full year of amortization related to intangible assets
acquired during fiscal 2009.

|                                     |  |      |       |   |      |   |      
|Total special charges                |  | $    | 5,695 |   |      | $ | 9,650

Special charges primarily consisted of costs incurred for employee terminations and were due to our reduction of
personnel resources driven by modifications of business strategy or business emphasis. Special charges may also include expenses incurred related to potential acquisitions, excess facility costs, and asset-related charges.

We rebalanced our workforce by 150 employees during the three months ended April 30, 2009. The reduction impacted several employee groups. Employee severance costs
of $4.0 million included severance benefits, notice pay, and outplacement services. The total rebalance charge represents the aggregate of numerous unrelated rebalance plans, none of which was individually material to our financial position or
results of operations. We determined termination benefit amounts based on employee status, years of service, and local statutory requirements. We communicated termination benefits to the affected employees prior to the end of the quarter in which we
recorded the charge. Approximately 40% of these costs were paid during the three months ended April 30, 2009. We expect to pay the remainder during fiscal 2010. There have been no significant modifications to the amount of these charges.

Other special charges for the three months ended April 30, 2009 included costs of $1.2 million related to advisory fees and charges of $0.2 million
related to a casualty loss.

We rebalanced our workforce by 110 employees during the three months ended April 30, 2008. The reduction impacted several
employee groups. Employee severance costs of $8.1 million included severance benefits, notice pay, and outplacement services. The total rebalance charge represents the aggregate of numerous unrelated rebalance plans, none of which was individually
material to our financial position or results of operations. We determined termination benefit amounts based on employee status, years of service, and local statutory requirements. We communicated termination benefits to the affected employees prior
to the end of the quarter in which we recorded the charge. The majority of these costs were paid during fiscal 2009. There have been no significant modifications to the amount of these charges.

Excess leased facility costs of $1.4 million during the three months ended April 30, 2008 were primarily due to the abandonment of two additional leased facilities
and a change in the estimate of sublease income of a previously abandoned leased facility.

Targeted Reductions for Fiscal 2010

For fiscal 2010, as part of our planning process, we targeted $35.0 million of reductions (inclusive of beneficial foreign currency movements) to our prior year base
operating expenses in Research and development, Marketing and selling, and General and administration. We identified and put in action a series of programs to reduce costs. Travel has been sharply restricted. We have frozen wages, curtailed hiring,
and selectively reduced employee compensation and benefits. We reduced headcount in the first quarter of fiscal 2010.

Overall operating expenses (before
Special Charges) were down approximately 1% as benefits from our cost reduction programs and favorable foreign currency movements of approximately $8.9 million were offset by costs associated with the operations of Flomerics and prior year annual
salary increases, which were not in effect in the first half of fiscal 2009. We expect trended cost savings to be more apparent in the second half of fiscal 2010 as costs associated with Flomerics operations and salary increases become
comparative on a quarterly basis.

We have operations in foreign jurisdictions where the U.S. dollar has strengthened relative to the prior year. Our
planned cost savings assume continued strength of the U.S. dollar relative to those currencies in most foreign jurisdictions compared to fiscal 2009 levels.

##### Table of Contents

We did not recognize meaningful savings from actions taken in the first quarter of fiscal 2010 associated with Special
charges due to the timing of employee rebalances. The benefit from actions taken this quarter is expected to occur in the remainder of fiscal 2010 in the form of employee expense reductions.

Our targeted cost reductions for fiscal 2010 do not contemplate an increase in costs resulting from potential acquisitions which we may or may not successfully complete
in fiscal 2010.

The decline in interest income for the three months ended April 30, 2009 compared to the three months ended
April 30, 2008 was primarily due to the decrease of interest earned on our cash, cash equivalents, and short-term investments of approximately $0.7 million resulting from a decline in our cash held in interest bearing accounts and a decline in
the interest rates received on interest bearing accounts.

The decrease in foreign currency exchange gain (loss) for the three months ended April 30,
2009 compared to the three months ended April 30, 2008 was primarily due to favorable movements of exchange rates on foreign exchange contracts relating to certain short-term balance sheet positions in Europe during the three months ended
April 30, 2008.

Interest Expense

|Interest expense             |  | $    | 4,151 |        | (13 | %) |      | $ | 4,755

The decrease in interest expense for the three months ended April 30, 2009 compared to the three months ended
April 30, 2008 was primarily due to the decrease in interest expense for the time value of foreign currency contracts of approximately $0.4 million as a result of declines in foreign exchange contract rates.

The results for both periods presented reflect the application of FSP APB 14-1 to our convertible debt.

Provision for Income Taxes

|---------------------------- |  | ---- | ----- | ------ | --- | - | ---- | - | ------ | -
|Three months ended April 30, |  | 2009 |       | Change |     |   | 2008 |  
|Income tax expense (benefit) |  | $    | 2,757 |        | 137 | % |      | $ | (7,549 | )

We recorded income tax expense of $2.8 million for the three months ended April 30, 2009 and income tax
benefit of $7.5 million for the three months ended April 30, 2008. Generally, the provision for income taxes is the result of the mix of profit and loss earned by us and our subsidiaries in tax jurisdictions with a broad range of income tax
rates, withholding taxes (primarily in certain foreign jurisdictions), changes in tax reserves, and the application of valuation allowances. On a quarterly basis, we evaluate our provision for income tax expense (benefit) based on our projected
results of operations for the full year and record an adjustment in the current quarter.

We expect to incur tax expense for the year ending January, 31,
2010, even though we project a loss on our income statement for the full fiscal year. This is primarily because we expect to record a net profit from international operations, thereby incurring expense while we anticipate losses in the U.S. Any tax
benefit in the U.S. will generally be offset by an increase in the valuation allowance on U.S. deferred tax assets. This inability to utilize the benefit of our U.S. losses is the primary reason for our expected negative tax rate for fiscal 2010.
For the three months ended April 30, 2009, our effective tax rate was (27)% after considering discrete items totaling $2.0 million of tax benefit. Our effective tax rate for the three months ended April 30, 2009 without discrete items was
(47)%. For fiscal 2010, we project a (48)% effective tax rate, with the inclusion of discrete items. This differs from tax computed at the U.S. federal statutory rate primarily due to:



| |  |  | Projected U.S. losses for which no tax benefit will be recognized;
| | - |  | ------------------------------------------------------------------



| |  |  | Withholding taxes in certain foreign jurisdictions;
| | - |  | ---------------------------------------------------

| |  |  | Increases in foreign tax reserves; and

| |  |  | Non-deductible employee stock purchase plan compensation expense.
| | - |  | -----------------------------------------------------------------

These differences are partially offset by:



| |  |  | The benefit of lower tax rates on earnings of foreign subsidiaries; and
| | - |  | -----------------------------------------------------------------------



| |  |  | The application of tax incentives for research and development in certain jurisdictions.
| | - |  | ----------------------------------------------------------------------------------------

Our current projected tax rate for fiscal 2010 could change significantly if actual results differ from our current outlook-based projections.

We have not provided for U.S. income taxes on the undistributed earnings of foreign subsidiaries because they are considered permanently re-invested outside of the U.S.
If repatriated, some of these earnings would generate foreign tax credits, which may reduce the federal tax liability associated with any future foreign dividend.

Under SFAS No. 109, Accounting for Income Taxes (SFAS 109), we determined deferred tax assets and liabilities based on differences between the financial reporting and tax basis of assets and liabilities. We calculated the
deferred tax assets and liabilities using the enacted tax rates and laws that will be in effect when we expect the differences to reverse. SFAS 109 provides for the recognition of deferred tax assets without a valuation allowance if realization of
such assets is more likely than not. Since 2004, we have determined it is uncertain whether our U.S. entity will generate sufficient taxable income and foreign source income to utilize foreign tax credit carryforwards, research and experimentation
credit carryforwards, and net operating loss carryforwards before expiration. Consistent with prior years, we recorded valuation allowances in fiscal 2009 and expect to continue to record valuation allowances in fiscal 2010 against the portion of
those net deferred tax assets for which realization is uncertain. Valuation allowances relating to non-U.S. taxing jurisdictions were based on historical earnings patterns, which indicated uncertainty that we will have sufficient income in the
appropriate jurisdictions to realize the full value of the assets. We will continue to evaluate the realizability of the deferred tax assets on a periodic basis.

We are subject to income taxes in the U.S. and in numerous foreign jurisdictions, and in the ordinary course of business there are many transactions and calculations where the ultimate tax determination is uncertain. The statute of
limitations for adjustments to our historic tax obligations will vary from jurisdiction to jurisdiction. In some cases it may be extended or be unlimited. Further, attribute carryforwards may be subject to adjustment after the expiration of the
statute of limitations of the year such attribute was originated. Our larger jurisdictions generally provide for a statute of limitations from three to five years. In the U.S., the statute of limitations remains open for fiscal years 2002 and
forward. We are currently under examination in various jurisdictions, including the U.S. The examinations are in different stages and timing of their resolution is difficult to predict. The examination in the U.S. by the Internal Revenue Service
(IRS) pertains to our 2002, 2003, and 2004 tax years. In March 2007, the IRS issued a Revenue Agents Report for 2002 through 2004 in which adjustments were asserted totaling $146.6 million of additional taxable income. The adjustments
primarily concern transfer-pricing arrangements related to intellectual property rights acquired in acquisitions that were transferred to a foreign subsidiary. Although we continue to contest the adjustments with the Appeals Office of the IRS, we
have reached a tentative settlement. The settlement is generally consistent with our reserve posture, and due to our valuation allowance position in the U.S., we do not expect any significant financial statement impact once this matter is
effectively settled. The statute of limitations remains open for years on and after 2004 in Ireland and Japan.

We have reserves for taxes to address
potential exposures involving tax positions that are being challenged or that could be challenged by taxing authorities even though we believe the positions we have taken are appropriate. We believe our tax reserves are adequate to cover potential
liabilities. We review the tax reserves as circumstances warrant and adjust the reserves as events occur that affect our potential liability for additional taxes. It is often difficult to predict the final outcome or timing of resolution of any
particular tax matter; and various events, some of which cannot be predicted, such as clarifications of tax law by administrative or judicial means, may occur and would require us to increase or decrease our reserves and effective tax rate. For the
three months ended April 30, 2009, we reflected a $6.5 million reduction in reserves for potential tax liabilities principally due to the expiration of the statute of limitations in certain jurisdictions, with $2.6 million of that reduction
included as a discrete item of tax benefit in the quarter. We expect to record additional reserves in future periods with respect to tax positions taken for the current year. It is reasonably possible that unrecognized tax positions may decrease by
up to $20.0 million due to settlements or expirations of the statute of limitations within the next twelve months. To the extent that uncertain tax positions resolve in our favor, it could have a positive impact on our effective tax rate. A
significant portion of reserves, which are expected to settle or expire within the next twelve months, may result in the booking of deferred tax assets subject to a valuation allowance for which no benefit would be recognized. Certain reductions in
our reserves may require cash payments. Income tax-related interest and penalties were $0.3 million for the three months ended April 30, 2009.

Effects of Foreign Currency Fluctuations

We generated nearly two-thirds of our revenues and approximately one-third of our expenses outside of the U.S. during the three months ended April 30, 2009 and 2008. For the three months ended April 30,
2009, approximately one-third of European revenues were subject to exchange rate fluctuations as they were booked in local currencies (euro and British pounds) compared to approximately one-fourth of European revenues for the three months ended
April 30, 2008. All other European revenue contracts are denominated and paid to us in the U.S. dollar while our European expenses, including substantial research and development operations, are paid in local currencies (euro and British
pounds) causing an overall short position in the euro and the British pound to the extent our expenses in those currencies exceed our revenues in those currencies. We therefore enter into foreign currency forward and option contracts to partially
offset these exposures. Any gain or loss on these contracts is classified as operating expense when the hedged transaction occurs. The strength of the U.S. dollar for the three months ended April 30, 2009 compared to the three months ended
April 30, 2008 resulted in approximately $4.1 million of operating expense savings associated with these currencies (euro and British pounds), net of hedge contract losses of approximately $2.0 million in the current period.

For the three months ended April 30, 2009, all Japanese revenues were subject to exchange rate fluctuations compared to approximately two-thirds of Japanese
revenues for the three months ended April 30, 2008. In addition, we experience greater inflows than outflows of Japanese yen as almost all Japanese-based customers contract and pay us in Japanese yen. We enter into foreign currency forward and
option contracts to partially offset this exposure. Any gain or loss on these contracts is classified as product revenue when the hedged transaction occurs. The strength of the U.S. dollar for the three months ended April 30, 2009 compared to
the three months ended April 30, 2008 resulted in approximately $0.3 million of incremental revenue associated with the Japanese yen, net of hedge contract losses of approximately $1.7 million in the current period. We experienced a favorable
currency movement in operating expenses in the Japanese yen of approximately $0.8 million for the three months ended April 30, 2009 compared to the three months ended April 30, 2008.

Exposures are aggregated on a consolidated basis to take advantage of natural offsets, however, substantial exposure remains. For balance sheet exposures we enter into short-term foreign currency forward contracts to
protect against currency exchange risk associated with existing assets and liabilities. For cash flow exposures, we enter into short-term foreign currency forward and option contracts to partially offset anticipated exposures. We generally enter
into option contracts at contract strike rates that are different than current market rates. As a result, any unfavorable currency movements below the strike rates will not be offset by the foreign currency option contract and could negatively
affect operating results. These contracts address anticipated future cash flows for periods up to one year and do not hedge 100% of the potential exposures related to these currencies. As a result, the effects of currency fluctuations could have a
substantial effect on our overall results of operations.

We incur operating expenses in foreign currencies other than the euro, British pound and Japanese
yen, for which natural revenue offsets are not available and the cash flows are not hedged. Expenses in these jurisdictions are exposed to foreign currency variances which affect our operating results. The strength of the U.S. dollar for the three
months ended April 30, 2009 compared to the three months ended April 30, 2008 resulted in approximately $5.6 million of operating expense savings associated with these non-hedged currencies in the current period.

Foreign currency translation adjustment, a component of Accumulated other comprehensive income reported in the Stockholders equity section of our Condensed
Consolidated Balance Sheets, was $18.7 million as of April 30, 2009 compared to $18.9 million as of January 31, 2009.

LIQUIDITY AND CAPITAL RESOURCES

Our primary ongoing cash requirements will be for product development, operating activities, capital expenditures, debt service, and acquisition opportunities that may arise. Our primary sources of liquidity are cash
generated from operations and borrowings under our revolving credit facility.

As of April 30, 2009, we had cash and cash equivalents of $78.8
million. The available cash and cash equivalents are held in accounts managed by third-party financial institutions and consist of invested cash and cash in our operating accounts.

The invested cash is invested in interest bearing funds managed by third-party financial institutions. To date, we have experienced no loss or lack of access to our invested cash; however, we can provide no assurances
that access to our cash and cash equivalents will not be impacted by adverse conditions in the financial markets.

At any point in time, we have
significant balances in operating accounts that are with individual third-party financial institutions, which may exceed the Federal Deposit Insurance Corporation insurance limits or other regulatory insurance program limits. While we monitor daily
the cash balances in our operating accounts and adjust the cash balances as appropriate, these cash balances could be impacted if the underlying financial institutions fail or are subject to other adverse conditions in the financial markets.

We anticipate that the following will be sufficient to meet our working capital needs on a short-term (twelve months or less) and long-term basis (more
than twelve months):



| |  |  | Current cash balances;
| | - |  | ----------------------



| |  |  | Anticipated cash flows from operating activities, including the effects of selling and financing customer term receivables;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | Amounts available under existing revolving credit facilities; and
| | - |  | -----------------------------------------------------------------



| |  |  | Other available financing sources, such as the issuance of debt or equity securities, although the capital markets have been volatile and we cannot assure you that
we will be able to raise debt or equity capital on acceptable terms.

Operating Activities

Cash flows from operating activities consist of net loss, adjusted for certain non-cash items and changes in operating assets and liabilities. Our cash flows from operating activities are significantly influenced by
the payment terms on our license agreements and by our sales of qualifying accounts receivable. As a result of the current global economic downturn, our customers may not be able to make future payments as scheduled or may seek to renegotiate
pre-existing contractual commitments due to adverse changes in their own businesses. Our customers inability to fulfill payment obligations could adversely affect our cash flow. Though we have not, to date, experienced a material level of
defaults, material payment defaults by our customers as a result of current economic conditions or otherwise could have a material adverse effect on our financial condition. To address these concerns, we are monitoring our accounts receivable
portfolio for customers with low or declining credit ratings and have increased our collection efforts over the last year.

|Average days sales outstanding in Trade accounts receivable, net |  |                | 51 days  |                  |   | 50 days 

The increase in the average days sales outstanding in Trade accounts receivable, net for the three months ended
April 30, 2009 compared to the three months ended January 31, 2009 was due to the decrease in revenue. The decrease in Trade accounts receivable, net for the three months ended April 30, 2009 compared to the three months ended
January 31, 2009 was due to decreased billings and improved collections.

##### Table of Contents

Excluding the current portion of term receivables of $142.6 million, average days sales outstanding were 51 as of
April 30, 2009. Excluding the current portion of term receivables of $139.1 million, average days sales outstanding were 50 as of January 31, 2009.

The current portion of term receivables is attributable to multi-year term license sales agreements. We include amounts for term agreements that are due within one year in Trade accounts receivable, net, and balances that are due in more
than one year in Term receivables, long-term. We use term agreements as a standard business practice and have a history of successfully collecting under the original payment terms without making concessions on payments, products, or services,
although the impact of current economic conditions on our customers could affect this performance. The increase in total term receivables from $285.8 million as of January 31, 2009 to $295.5 million as of April 30, 2009 was primarily due
to the timing of billings during the three months ended April 30, 2009 compared to the three months ended January 31, 2009.

We have entered into
agreements to sell qualifying accounts receivable from time to time to certain financing institutions on a non-recourse basis. For the three months ended April 30, 2009, we sold trade receivables of $4.9 million and term receivables of $9.5
million for net proceeds of $13.3 million. For the three months ended April 30, 2008, we sold trade receivables of $13.1 million and term receivables of $11.2 million for net proceeds of $23.3 million. We have not set a target for the sale of
accounts receivable for the remainder of fiscal 2010.

Accrued Payroll and Related Liabilities



|                                        |  |                |        |                  |   |       
|--------------------------------------- |  | -------------- | ------ | ---------------- | - | ------
|As of                                   |  | April 30, 2009 |        | January 31, 2009
|Accrued payroll and related liabilities |  | $              | 54,991 |                  | $ | 65,687

The decrease in Accrued payroll and related liabilities is primarily due to payments made during the first quarter
(as is typical) on year-end bonus accruals of approximately $8.0 million and commission accruals of approximately $4.0 million. We generally experience higher accrued payroll and related liability balances at year end primarily due to increased
commission accruals associated with an increase in revenues in the fourth quarter. Additionally, we generally experience an increase in bonus accruals at year end which result from a year-to-date true-up of amounts based on the full year achievement
of results.

Investing Activities

Excluding
short-term investments, cash used in investing activities for the three months ended April 30, 2009 primarily consisted of cash paid for capital expenditures.

Expenditures for property, plant, and equipment decreased to $4.6 million for the three months ended April 30, 2009 compared to $9.0 million for the three months ended April 30, 2008. The expenditures for property, plant, and
equipment for the three months ended April 30, 2009 were primarily a result of spending on information technology and infrastructure improvements within facilities. We expect total capital expenditures for property, plant, and equipment for
fiscal 2010 to be approximately $30.0 million.

We plan to finance our continued investments in business acquisitions and property, plant, and equipment
using cash on hand, cash generated from operating activities, and borrowings under the revolving credit facility.

Financing Activities

For the three months ended April 30, 2009, cash used in financing activities consisted primarily of:



| |  |  | $6.6 million primarily for the remittance of previously factored receivables to the appropriate financial institutions; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | $2.1 million for the repurchase of notes payable.
| | - |  | -------------------------------------------------

We may elect to purchase or otherwise retire some or all of our debentures with cash, stock, or other assets from time to time in the open market or privately negotiated transactions, either directly or through intermediaries, or by tender
offer when we believe that market conditions are favorable to do so. Such purchases may have a material effect on our liquidity, financial condition, and results of operations.

Other factors affecting liquidity and capital resources

6.25% Debentures due 2026

In March 2006, we issued $200.0 million of 6.25% Debentures in a private offering pursuant to SEC Rule 144A under the Securities Act of 1933. Interest on the 6.25%
Debentures is payable semi-annually in March and September. The 6.25%

##### Table of Contents

Debentures are convertible, under certain circumstances, into our common stock at a conversion price of $17.968 per share for a total of 9,183
thousand shares as of April 30, 2009.These circumstances generally include:



| |  |  | The market price of our common stock exceeding 120% of the conversion price;
| | - |  | ----------------------------------------------------------------------------



| |  |  | The market price of the 6.25% Debentures declining to less than 98% of the value of the common stock into which the 6.25% Debentures are convertible;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A call for the redemption of the 6.25% Debentures;
| | - |  | --------------------------------------------------



| |  |  | Specified distributions to holders of our common stock;
| | - |  | -------------------------------------------------------



| |  |  | If a fundamental change, such as a change of control, occurs; or
| | - |  | ----------------------------------------------------------------



| |  |  | During the ten trading days prior to, but not on, the maturity date.
| | - |  | --------------------------------------------------------------------

Upon conversion, in lieu of shares of our common stock, for each $1 thousand principal amount of the 6.25% Debentures a holder will receive an amount of cash equal to the lesser of: (i) $1 thousand or
(ii) the conversion value of the number of shares of our common stock equal to the conversion rate. If such conversion value exceeds $1 thousand, we will also deliver, at our election, cash or common stock, or a combination of cash and common
stock with a value equal to the excess. If a holder elects to convert their 6.25% Debentures in connection with a fundamental change in the company that occurs prior to March 6, 2011, the holder will also be entitled to receive a make whole
premium upon conversion in some circumstances. The 6.25% Debentures rank pari passu with the Floating Rate Debentures. We may redeem some or all of the 6.25% Debentures for cash on or after March 6, 2011. The holders, at their option, may
redeem some or all of the 6.25% Debentures for cash on March 1, 2013, 2016, or 2021. During the three months ended April 30, 2009, we did not repurchase any 6.25% Debentures and the principal amount of $165.0 million remains outstanding.

Floating Rate Debentures due 2023

In August 2003, we
issued $110.0 million of Floating Rate Debentures in a private offering pursuant to SEC Rule 144A under the Securities Act of 1933. Interest on the Floating Rate Debentures is payable quarterly in February, May, August, and November at a variable
interest rate equal to 3-month London Interbank Offered Rate (LIBOR) plus 1.65%. The effective interest rate was 2.97% for the three months ended April 30, 2009. The Floating Rate Debentures are convertible, under certain circumstances, into
our common stock at a conversion price of $23.40 per share for a total of 1,443 thousand shares as of April 30, 2009. These circumstances generally include:



| |  |  | The market price of our common stock exceeding 120% of the conversion price;
| | - |  | ----------------------------------------------------------------------------



| |  |  | The market price of the Floating Rate Debentures declining to less than 98% of the value of the common stock into which the Floating Rate Debentures are
convertible; or
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A call for redemption of the Floating Rate Debentures or certain other corporate transactions.
| | - |  | ----------------------------------------------------------------------------------------------

The conversion price may also be adjusted based on certain future transactions, such as stock splits or stock dividends. We may redeem some or all of the Floating Rate
Debentures for cash at 101.61% of the face amount, with the premium reducing to 0.81% on August 6, 2009 and 0% on August 6, 2010. The holders, at their option, may redeem some or all of the Floating Rate Debentures for cash on
August 6, 2010, 2013, or 2018. During the three months ended April 30, 2009, we repurchased, on the open market, and retired Floating Rate Debentures with a principal balance of $2.3 million at a discount. As a result, a principal amount
of $33.8 million is outstanding as of April 30, 2009.

Revolving Credit Facility

In June 2005, we entered into a syndicated, senior, unsecured, four-year revolving credit facility that replaced an existing three-year revolving credit facility. In April 2008, we extended this revolving credit
facility by two years to June 1, 2011. In May 2008, we increased the maximum borrowing capacity from $120.0 million to $140.0 million and retained an option to increase it by an additional $10.0 million in the future. In March 2009, we amended
the revolving credit facility to reduce the minimum tangible net worth calculated as of January 31, 2009, which is used as the starting point for future calculations, by $15.0 million, and to make certain other changes reflected in the
discussion below. Under this revolving credit facility, we have the option to pay interest based on: (i) LIBOR with varying maturities which are commensurate with the borrowing period we select, plus a spread of between 1.0% and 1.6% or
(ii) a base rate plus a spread of between 0.0% and 0.6%, based on a pricing grid tied to a financial covenant. The base rate is defined as: (i) the higher of the federal funds rate, as defined, plus 0.5%, (ii) the prime rate of the
lead bank, or (iii) one-month LIBOR plus 1.0%. As a result, our interest expense associated with borrowings under this revolving credit facility will vary with market interest rates. In addition, commitment fees are payable on the unused
portion of the revolving credit facility at rates between 0.25% and 0.35% based on a pricing grid tied to a financial covenant. We paid commitment fees of $77 thousand for the three months ended April 30, 2009

##### Table of Contents

compared to $75 thousand for the three months ended April 30, 2008. This revolving credit facility contains certain financial and other covenants,
including the following:



| |  |  | Our adjusted quick ratio (ratio of sum of cash and cash equivalents, short-term investment, and net current receivables to total current liabilities) shall not be
less than 0.85;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our tangible net worth (stockholders equity less goodwill and other intangible assets) must exceed the calculated required tangible net worth as defined in
the credit agreement, which establishes a fixed level of required tangible net worth, and then increases that required level each quarter by 70% of any positive net income in the quarter (but in the aggregate no more than 70% of positive net income
for any full fiscal year), 100% of the amortization of intangible assets in the quarter, and 100% of certain stock issuance proceeds, which increases are offset by certain amounts of acquired intangible assets;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our leverage ratio (ratio of total liabilities less subordinated debt to sum of subordinated debt and tangible net worth) shall not be greater than 2.20;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our senior leverage ratio (ratio of total debt less subordinated debt to sum of subordinated debt and tangible net worth) shall be less than 0.90; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our minimum cash and accounts receivable ratio (ratio of sum of cash and cash equivalents, short-term investments, and 47.5% of net current accounts receivable, to
outstanding credit agreement borrowings) shall not be less than 1.25.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The revolving credit facility prevents us from paying dividends.

We were in compliance with all financial covenants as of April 30, 2009. If we were to fail to comply with the financial covenants and did not obtain
a waiver from our lenders, we would be in default under the revolving credit facility and our lenders could terminate the facility and demand immediate repayment of all outstanding loans under the revolving credit facility. The declaration of an
event of default could have a material adverse effect on our financial condition. We could also find it difficult to obtain other bank lines or credit facilities on comparable terms.

We did not borrow any amounts under the revolving credit facility during the three months ended April 30, 2009. As of April 30, 2009, we had an outstanding balance borrowed under the facility of $20.0
million. The interest rate as of April 30, 2009 was 3.85%.

OFF-BALANCE SHEET ARRANGEMENTS

We do not have off-balance sheet arrangements, financings, or other similar relationships with unconsolidated entities or other persons, also known as special purpose
entities. In the ordinary course of business, we lease certain real properties, primarily field sales offices, research and development facilities, and equipment.

OUTLOOK FOR FISCAL 2010

We expect revenues for the second quarter of fiscal 2010 to be approximately $165.0 million, with a net loss
per share for the same period of approximately $(0.41).

We place our investments in instruments that meet high quality credit standards, as specified
in our investment policy. The policy also limits the amount of credit exposure to any one issuer and type of instrument. We do not expect any material loss with respect to our investment portfolio.

The table below presents the carrying amount and related weighted-average fixed interest rates for our investment portfolio. The carrying amount approximates fair value
as of April 30, 2009. In accordance with our investment policy, all short-term investments mature in twelve months or less.

We had convertible subordinated debentures with a principal balance of $165.0 million outstanding with a fixed
interest rate of 6.25% as of April 30, 2009. For fixed rate debt, interest rate changes affect the fair value of the debentures but do not affect earnings or cash flow.

We had floating rate convertible subordinated debentures with a principal balance of $33.8 million outstanding with a variable interest rate of 3-month London Interbank Offered Rate (LIBOR) plus 1.65% as of
April 30, 2009. For variable interest rate debt, interest rate changes generally do not affect the fair market value but do affect earnings and cash flow. If the interest rates on the variable rate borrowings were to increase or decrease by 1%
for the year and the level of borrowings outstanding remained constant, annual interest expense would increase or decrease by approximately $0.3 million.

As of April 30, 2009, we had a syndicated, senior, unsecured, revolving credit facility, which expires on June 1, 2011. Borrowings under the revolving credit facility are permitted to a maximum of $140.0 million. Under this
revolving credit facility, we have the option to pay interest based on: (i) LIBOR with varying maturities which are commensurate with the borrowing period we select, plus a spread of between 1.0% and 1.6%, or (ii) a base rate plus a spread
of between 0.0% and 0.6%, based on a pricing grid tied to a financial covenant. The base rate is defined as the higher of (i) the federal funds rate, as defined, plus 0.5%, (ii) the prime rate of the lead bank, or (iii) one-month
LIBOR plus 1.0%. As a result, our interest expense associated with borrowings under this revolving credit facility will vary with market interest rates. This revolving credit facility contains certain financial and other covenants, including
financial covenants requiring the maintenance of specified liquidity ratios, leverage ratios, and minimum tangible net worth as well as restrictions on the payment of cash dividends. As of April 30, 2009, we had an outstanding balance of $20.0
million. The interest rate as of April 30, 2009 was 3.85%.

Including the $20.0 million outstanding under the revolving credit facility, we had
short-term borrowings of $24.1 million outstanding as of April 30, 2009 with variable rates based on market indexes. For variable interest rate debt, interest rate changes generally do not affect the fair market value, but do affect future
earnings and cash flow. If the interest rates on the variable rate borrowings were to increase or decrease by 1% for the year and the level of borrowings outstanding remained constant, annual interest expense would increase or decrease by
approximately $0.2 million.

Foreign Currency Risk

We transact business in various foreign currencies and have established a foreign currency hedging program to hedge certain foreign currency forecasted transactions and exposures from existing assets and liabilities.
Our derivative instruments consist of short-term, foreign currency forward and option contracts of not more than a year. We enter into contracts with counterparties who are major financial institutions, as such we do not expect material losses as a
result of defaults by our counterparties. We do not hold or issue derivative financial instruments for speculative or trading purposes.

We enter into foreign currency forward contracts to protect against currency exchange risk associated with
expected future cash flows. Our practice is to hedge a majority of our existing material foreign currency transaction exposures, which generally represent the excess of expected euro and British pound expenses over expected euro and British pound
denominated revenues, and the excess of Japanese yen denominated revenue over expected Japanese yen expenses. We also enter into foreign currency forward contracts to protect against currency exchange risk associated with existing assets and
liabilities.

The following table provides volume information about our foreign currency forward program. The information provided is in U. S. dollar
equivalent amounts. The table presents the gross notional amounts, at contract exchange rates, and the weighted average contractual foreign currency exchange rates. These forward contracts mature within the next twelve months.

|Item 4. | Controls and Procedures
|------- | -----------------------

(1) Evaluation of Disclosure Controls
and Procedures

We maintain disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as
amended (Exchange Act), that are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange
Commissions rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate, to allow timely decisions regarding required
disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control
objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure
controls and procedures as of the end of the period covered by this report. Based on the foregoing, our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable
assurance level as of the end of the period covered by this report.

(2) Changes in Internal Controls Over Financial Reporting

There has been no change in our internal control over financial reporting that occurred during the last fiscal quarter that has materially affected, or is reasonably
likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION



|Item 1A. | Risk Factors
|-------- | ------------

The forward-looking statements contained under
Outlook for Fiscal 2010 in Part I, Item 2. 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. Moreover, from time to time, we may issue other forward-looking statements. Forward-looking statements regarding financial performance in future periods, including the statements under Outlook for
Fiscal 2010, 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. Our business faces many risks, and set forth below are some of the 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 (U.S.) and international economies may harm our business.

Our revenue levels are generally dependent on the level of technology capital spending, which includes worldwide expenditures for electronic design automation (EDA) software, hardware, and consulting services. The
global economy continues in recession, with extraordinary volatility, with uncertainty in the credit markets and banking systems, reduced corporate profits and capital spending, and significant job losses. A number of our customers are also
experiencing liquidity concerns, business insolvencies, and bankruptcies. For example, the semiconductor manufacturing sector has experienced a number of bankruptcies and a number of our competitors have reported significant revenue and profit
declines. This volatility and uncertainty about future economic conditions could adversely affect our customers and postpone decisions to license or purchase our products, decrease our customers spending, and jeopardize or delay our
customers ability or willingness to make payment obligations, any of which could adversely affect our business. Consulting spending, which tends to be more discretionary than software and services spending, could be particularly vulnerable to
continued economic weakness in our customers business. We cannot predict the duration of the global economic downturn or subsequent recovery.

Customer payment defaults or related issues could adversely affect our financial condition and results of operations.

We have
customer payment obligations not yet due that are attributable to software we have already delivered. These customer obligations are typically not cancelable, but will not yield the expected revenue and cash flow if the customer defaults or declares
bankruptcy and fails to pay amounts owed. In these cases, we may take legal action to recover amounts owed if warranted. Moreover, existing customers may seek to renegotiate pre-existing contractual commitments due to adverse changes in their own
businesses, particularly in the current troubled economic environment. Though we have not, to date, experienced a material level of defaults or renegotiated a material level of pre-existing contractual commitments, any material payment default by
our customers or significant reductions in existing contractual commitments could have a material adverse effect on our financial condition and results of operations. These risks may be exacerbated by the current global economic downturn because our
revenue forecasts assume: (i) customers whose payments are recognized as revenue only when paid will make future payments as scheduled and (ii) customers whose credit ratings and financial circumstances have deteriorated since we
originally booked contracts with them will make future payments as scheduled.

Our forecasts of our revenues and earnings outlook may be inaccurate.

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 fiscal quarter attempting to obtain more favorable transaction terms.

Our business could be impacted by fluctuations in quarterly results of operations due to customer seasonal purchasing patterns, the timing of significant orders, and the mix of licenses and products purchased by our customers.

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 typically 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. If our planned contract renewals are delayed or the average size of renewed contracts do not increase as we anticipate, we could fail to meet our and investors expectations,
which could have a material adverse impact on our stock price.

Our revenues are also affected by the mix of licenses entered into where we recognize
software revenues as payments become due and payable, on a cash basis, 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, for instance, when
the customer is provided with rights to unspecified or unreleased future products. A shift in the license mix toward increased ratable, due and payable, and/or cash-based revenue recognition could result in increased deferral of software revenues to
future periods and would decrease current revenues, which could result in us not meeting near-term revenue expectations.

The gross margin on our software
is greater than that for our hardware emulation systems, software support, and professional services. Therefore, our gross margin may vary as a result of the mix of products and services 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 relatively large
negative effect on resulting earnings. If anticipated revenues do not materialize as expected, our gross margins and operating results could be materially adversely impacted.

We face intense competition in the EDA industry.

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 certain software products at low prices for promotional
purposes or as a long-term pricing strategy. These practices could significantly reduce demand for our products or constrain prices we can charge.

We
currently compete primarily with two large companies: Cadence Design Systems, Inc. (Cadence) and Synopsys, Inc. We also compete with numerous smaller companies and compete with manufacturers of electronic devices that have developed their own EDA
products internally.

Our international operations and the effects of foreign currency fluctuations expose us to additional risks.

We generate nearly two-thirds of our revenues from customers outside the U.S. and we generate approximately one-third of our expenses outside the
U.S. Significant changes in currency exchange rates could have an adverse impact on us. For further discussion of foreign currency effects, see Effects of Foreign Currency Fluctuations discussion in Part I, Item 2.
Managements Discussion and Analysis of Financial Condition and Results of Operations. 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, local labor laws, 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. Our cost savings efforts for fiscal 2010 depend on continued strength of the U.S. dollar compared to fiscal 2009 levels, particularly relative to the
currencies other than those we hedge (the euro, British pound, and Japanese yen).

We derive a substantial portion of our revenues from relatively
few product groups.

We derive a substantial portion of our revenues from sales of relatively few product groups and related support services. As
such, any factor adversely affecting sales of these products, including the product release cycles, market acceptance, product competition, performance and reliability, reputation, price competition, and economic and market conditions, could harm
our operating results.

We may be required to record impairment charges on our goodwill and other intangible assets.

We perform an analysis on our goodwill balances to test for impairment on an annual basis or whenever events occur that may indicate impairment possibly exists. Goodwill
is deemed to be impaired if the carrying value of a reporting unit exceeds its estimated fair value. Long-lived assets and amortizable intangible assets are tested for impairment when events or circumstances arise indicating that their carrying
value may not be recoverable. An impairment charge is only deemed to have occurred if the sum of the forecasted undiscounted net cash flows related to the asset is less than the carrying value of the intangible asset we are testing for impairment.
If the forecasted cash flows are less than the carrying value, then we must write down the carrying value to its estimated fair value. As of April 30, 2009, we had a goodwill balance of $442 million and intangible assets of $34 million. Going
forward, we will continue to review our goodwill and other intangible assets for



41

##### Table of Contents

possible impairment or events or circumstances that would require us to test for impairment. Any impairment charges could adversely affect our future
earnings. Goodwill impairment analysis and measurement is a process that requires significant judgment. A decline in our stock price and resulting market capitalization below the carrying value of our reporting units would result in the need for us
to test for impairment if we determine that the decline is sustained. We cannot be certain that a future downturn in our business, changes in market conditions or a longer-term decline in our share price and market capitalization will not
result in an impairment of goodwill and the recognition of a material impairment charge in future periods, which could have a material adverse effect on our financial condition and results of operations.

We are subject to the cyclical nature of the integrated circuit (IC) and electronics systems industries.

Purchases of our products and services are highly dependent upon new design projects initiated by customers in the 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 or decline in general economic conditions. These downturns could cause diminished product
demand, production overcapacity, high inventory levels, and accelerated erosion of average selling prices.

Customer payment defaults could adversely
affect our timing of revenue recognition.

We use fixed-term license agreements as standard business practices with customers we believe are
credit-worthy. These multi-year, multi-element term license agreements have payments spread over the license term and are typically about three years in length for semiconductor companies and about four years in length for military and aerospace
companies. 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 these agreements, our results of operations could be materially adversely impacted. We use these fixed-term license agreements as a standard business practice and have 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 the terms of the agreements, then revenue would be required to be recognized as the payments
become due and payable over the license term. This change could have a material impact on our results.

As a result of the current global economic
downturn, our customers may not be able to make future payments as scheduled or may seek to renegotiate pre-existing contractual commitments due to adverse changes in their own businesses. Our customers inability to fulfill payment obligations
could adversely affect our cash flow. Though we have not, to date, experienced a material level of defaults, our favorable collection experience may not continue and material payment defaults by our customers as a result of current economic
conditions or otherwise could have a material adverse effect on our financial condition, results of operations, and cash flow.

During the quarter
ended April 30, 2009, two customers accounted for a significant portion of our revenues.

During the quarter ended April 30, 2009, two of our
customers accounted for approximately 25% of our total revenues. We expect that these two customers will continue to represent a significant portion of our revenue in the future. If either of these two customers defaults, declares bankruptcy, or
otherwise fails to pay amounts owed, it could have a material adverse effect on our financial condition and results of operations.

IC and printed
circuit board (PCB) technology evolves rapidly.

The complexity of ICs and PCBs continues to rapidly increase. In response to this increasing
complexity, new design tools and methodologies must be invented or acquired quickly to remain competitive. If we fail to quickly respond to new technological developments, our products could become obsolete or uncompetitive, which could materially
adversely impact our business.

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 support or service costs.
| | - |  | -----------------------------------

In addition, we
include third party technology in our products and we rely on those third parties to provide support services to us. Failure of those third parties to provide necessary support services could materially adversely impact our business.

Long sales cycles and delay in customer completion 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.

Disruptions of our indirect sales channel could affect our future operating results.

Our indirect sales channel is comprised primarily of independent distributors and sales representatives. Our relationships with these channel participants are important
elements of our marketing and sales efforts. Our financial results could be adversely affected if our contracts with channel participants were terminated, if our relationships with channel participants were to deteriorate, if any of our competitors
enter into strategic relationships with or acquire a significant channel participant, or if the financial condition of our channel participants were to weaken. In addition, we recently changed from a territory-based sales organization to an
account-based organization with an increased emphasis upon our distributors and sales representatives. If this transition takes longer than expected to fully implement, it could adversely affect our financial results in the short-term.

Any loss of our leadership position in certain segments of the EDA market could harm our business.

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 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.

Accounting rules governing revenue recognition are complex and may change.

The accounting rules governing software revenue recognition are complex and have been subject to authoritative interpretations that have generally made it more difficult
to recognize software 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 near-term revenue expectations.

We may have additional tax liabilities.

Significant
judgments and estimates are required in determining the provision for income taxes and other tax liabilities. Our tax expense may be impacted if our intercompany transactions, which are required to be computed on an arms-length basis, are
challenged and successfully disputed by the tax authorities. Also, our tax expense could be impacted depending on the applicability of withholding taxes on software licenses and related intercompany transactions in certain jurisdictions. In
determining the adequacy of income taxes, we assess the likelihood of adverse outcomes resulting from the Internal Revenue Service (IRS) and other tax authorities examinations. The IRS and tax authorities in countries where we do business
regularly examine our tax returns. The ultimate outcome of these examinations cannot be predicted with certainty. Should the IRS 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. We were issued a Revenue Agents Report in March 2007. See Provision for Income Taxes in Part I, Item 2.
Managements Discussion and Analysis of Financial Condition and Results of Operations for additional discussion.

Forecasting our
income tax rate is complex and subject to uncertainty.

The computation of income tax expense (benefit) is complex as it is based on the laws of
numerous taxing jurisdictions and requires significant judgment on the application of complicated rules governing accounting for tax provision under U.S. generally accepted accounting principles. Income tax expense (benefit) for interim quarters is
based on a forecast of our global tax rate for the year, which includes forward looking financial projections, including the expectations of profit and loss by jurisdiction, and contains numerous assumptions. Various items cannot be accurately
forecasted, and may be treated as discrete accounting. Examples of items which could cause variability in the rate include tax deductions for stock option expense, application of transfer pricing rules, and changes in our valuation allowance for
deferred tax assets. Future events, such as changes in our business and the tax law in the jurisdictions where we do business, could also affect our rate. For these reasons, our global tax rate may be materially different than our forecast.

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



43



---

##### Table of Contents

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.

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 could realize little or no revenues related to our investment in research and
development.

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 we 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 ongoing 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;
| | - |  | --------------------



| |  |  | Unanticipated litigation in connection with or as a result of an acquisition, including claims from terminated employees, customers, or third parties;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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 could 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.

We may not adequately protect our
proprietary rights or we may fail to obtain software or other intellectual property licenses.

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 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 U.S. law protects these rights in the U.S.



44

##### Table of Contents

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. Failure to obtain software or other intellectual property licenses or rights from third parties on favorable terms could materially adversely impact
us.

Litigation may materially adversely impact us.

Litigation may result in monetary damages, 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.

Third parties may claim infringement or misuse of intellectual property rights.

We periodically receive notices from others claiming infringement, or other misuse of their intellectual property rights or breach of our agreements with them. We expect
the number of such claims will increase as the number of products and competitors in our industry segments grows, the functionality of products overlap, the use and support of third-party code (including open source code) becomes more prevalent in
the software industry, and the volume of issued software patents continues to increase. Responding to any such claim, regardless of its validity, could:



| |  |  | Be time-consuming, costly and/or result in litigation;
| | - |  | ------------------------------------------------------



| |  |  | Divert managements time and attention from developing our business;
| | - |  | --------------------------------------------------------------------



| |  |  | Require us to pay monetary damages or enter into royalty and licensing agreements that we would not normally find acceptable;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | Require us to stop selling or to redesign certain of our products;
| | - |  | ------------------------------------------------------------------



| |  |  | Require us to release source code to third parties, possibly under open source license terms;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | Require us to satisfy indemnification obligations to our customers; or
| | - |  | ----------------------------------------------------------------------



| |  |  | Otherwise adversely affect our business, results of operations, financial condition, or cash flows.
| | - |  | ---------------------------------------------------------------------------------------------------

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. Our failure to hire and retain such personnel could impair our ability to develop new products and manage our business effectively.

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 U.S. 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 in an armed conflict and could negatively impact our business. We currently have operations in Pakistan, Egypt, India, 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.

More generally, any of these events could cause consumer confidence and spending to decrease or result in increased volatility in the U.S. and worldwide financial markets and economy. They also could result in economic
recession in the U.S. or abroad. Any of these occurrences could have a significant impact on our operating results, revenues, and costs and could result in volatility of the market price for our common stock.

Our articles of incorporation and Oregon law may have anti-takeover effects.

Our board of directors has the authority, without action by the shareholders, to designate and issue up to 1,200,000 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 to acquire control of us through a proxy contest or the election of a majority of the board of directors. The potential issuance of incentive stock and the
provisions of the Oregon Control Share Act and the Business Combination Act could have the effect of delaying, deferring, or preventing a change of control of us, could discourage bids for our common stock at a premium over the market price of our
common stock and could materially adversely impact the market price of, and the voting and other rights of the holders of, our common stock.

We have a substantial level of indebtedness.

As of April 30, 2009, we had $216.2 million of outstanding indebtedness, which includes $33.8 million of Floating Rate Convertible Subordinated Debentures (Floating Rate Debentures) due 2023, $152.7 million of
6.25% Convertible Subordinated Debentures (6.25% Debentures) due 2026, and $29.7 million in short-term borrowings. 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 Floating Rate Debentures and
6.25% Debentures; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Place us at a competitive disadvantage relative to less leveraged competitors and competitors that have greater access to capital resources.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------

If we experience a decline in revenues, 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.

Our stock price could become more
volatile, and your investment could lose value.

All of the factors discussed in this section could affect our stock price. The timing of
announcements in the public market regarding new products, product enhancements, or technological advances by our competitors or us, and any announcements by us of acquisitions, major transactions, or management changes could also affect our stock
price. Our stock price is subject to speculation in the press and the analyst community, changes in recommendations or earnings estimates by financial analysts, changes in investors or analysts valuation measures for our stock, our
credit ratings, and market trends unrelated to our performance. A significant drop in our stock price could also expose us to the risk of securities class actions lawsuits, which could result in substantial costs and divert managements
attention and resources, which could adversely affect our business.

Our revolving credit facility has financial and non-financial covenants, and
default of any covenant could materially adversely impact us.

Our bank revolving credit facility imposes operating restrictions on us in the
form of financial and non-financial covenants. Financial covenants include adjusted quick ratio, minimum tangible net worth, leverage ratio, senior leverage ratio, and minimum cash and accounts receivable ratio. If we were to fail to comply with the
financial covenants and did not obtain a waiver from our lenders, we would be in default under the revolving credit facility and our lenders could terminate the facility and demand immediate repayment of all outstanding loans under
the revolving credit facility. The declaration of an event of default could have a material adverse effect on our financial condition. We could also find it difficult to obtain other bank lines or credit facilities on comparable
terms.
