FORM 10-K FOR THE FISCAL YEAR ENDED MARCH 31, 2007

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

LIQUIDITY AND CAPITAL RESOURCES, PAGE 37

1.   WE NOTE THAT YOU PROVIDE LITTLE OR NO DISCUSSION OF CASH FLOWS FROM
     OPERATING ACTIVITIES. IN THIS REGARD, WE NOTE THAT THERE WERE MATERIAL
     CHANGES IN SEVERAL WORKING CAPITAL LINE ITEMS HOWEVER YOU HAVE NOT
     DISCLOSED WHY THESE CHANGES OCCURRED AND HOW THEY IMPACTED OPERATING CASH
     FLOW. WHEN PREPARING THE DISCUSSION AND ANALYSIS OF OPERATING CASH FLOWS,
     YOU SHOULD ADDRESS MATERIAL CHANGES IN THE UNDERLYING DRIVERS THAT AFFECT
     THESE CASH FLOWS. THESE DISCLOSURES SHOULD ALSO INCLUDE A DISCUSSION OF THE
     UNDERLYING REASONS FOR CHANGES IN WORKING CAPITAL ITEMS THAT AFFECT
     OPERATING CASH FLOWS. IN THIS REGARD, PLEASE TELL US HOW YOU CONSIDERED THE
     GUIDANCE IN SECTION IV.B.1. OF SEC RELEASE 33-8350.

     Section IV.B.1. of SEC Release 33-8350 states, in relevant part:

          When preparing the discussion and analysis of operating cash flows,
          companies should address material changes in the underlying drivers
          (e.g. cash receipts from



          the sale of goods and services and cash payments to acquire materials
          for manufacture or goods for resale), rather than merely describe
          items identified on the face of the statement of cash flows such as
          the reconciling items used in the indirect method of presenting cash
          flows.

     We acknowledge that our discussion of cash flows from operating activities
     should have been more robust. The following is a revised operating section
     for the Liquidity and Capital Resources discussion to meet the criteria of
     SEC Release 33-8350. We propose to modify future filings to provide
     enhanced disclosure of material changes in underlying drivers that affect
     operating cash flows.

     LIQUIDITY AND CAPITAL RESOURCES:

     As of March 31, 2007, cash and cash equivalents and investments totaled
     approximately $439.1 million.

     We believe cash flow from operations will be sufficient to meet operating
     cash needs for the foreseeable future. We anticipate borrowing up to $300.0
     million in order to fund the planned expansion of the stock repurchase
     program. We also continue to evaluate business acquisition opportunities
     that fit our strategic plans.

     Net cash provided by operating activities:

     For the three years presented, we have been profitable and net income has
     been a primary source of cash from operating activities. During fiscal
     2007, 2006, and 2005 cash flow from operations was $204.7 million, $229.7
     million and $242.3 million, respectively. Depreciation and amortization
     added to net income, $55.0, $50.2 million and $56.4 million in fiscal 2007,
     2006 and 2005, respectively, to provide cash from operating activities.

     Our cash provided by operations is also impacted by changes in working
     capital accounts. Changes in accounts receivable and deferred revenue have
     typically had the largest impact on our cash flows. The Company allows for
     deferred payment terms on multi-year products contracts.

     Net cash from operating activities decreased $25.0 million during fiscal
     2007 as compared to fiscal 2006. The increase in net income in fiscal 2007
     was offset by the following items: in fiscal 2007 and 2006 the net change
     in accounts receivable contributed to cash flows. Prepaid expenses and
     other current assets increased primarily due to the fiscal 2007 IBM unused
     commitment balance of $10.7 million (see Note 14 of the Consolidated
     Financial Statements) not being received as of March 31, 2007. The change
     in accounts payable and accrued expenses significantly declined in fiscal
     2007. The decline was primarily the result of the reversal of income tax
     reserves of $26.6 million (see Note 12 of the Consolidated Financial
     Statements), reduction in deferred rent and bonus and commission accruals
     of $6.6 million, the



     decline in account payable of $5.4 million and a decline in the
     restructuring accrual of $3.5 million.

     Net cash from operating activities decreased $12.6 million during fiscal
     2006 as compared to fiscal 2005. The increase to net income in fiscal 2006
     and the positive contribution of the net change in accounts receivable was
     offset by the timing of tax payments and the increase in the deferred
     revenue balance during fiscal 2005. The deferred revenue balance increased
     in fiscal 2005 as a result of a $20 million prepayment by IBM under the
     settlement agreement discussed in Note 14 to the Consolidated Financial
     Statements and deferred revenue associated with several large transactions
     that were recorded during the year.

FINANCIAL STATEMENTS

CONSOLIDATED STATEMENTS OF OPERATIONS, PAGE 44

2.   YOU DISCLOSE ON PAGE 47 THAT CERTAIN REVENUE IS RECOGNIZED RATABLY DUE TO
     THE LACK OF VSOE. PLEASE TELL US WHERE YOU INCLUDED THE REVENUE FOR THESE
     BUNDLED ARRANGEMENTS IN YOUR STATEMENT OF OPERATIONS. FOR INSTANCE, TELL US
     WHETHER THE REVENUE IS INCLUDED IN A SINGLE LINE ITEM (I.E. LICENSE FEES,
     MAINTENANCE FEES OR PROFESSIONAL SERVICES FEES) OR TELL US IF THE COMPANY
     ALLOCATES THE REVENUE FROM THESE ENGAGEMENTS AMONGST THE VARIOUS REVENUE
     LINE ITEMS BASED ON A CERTAIN METHODOLOGY AND IF SO, PLEASE DESCRIBE SUCH
     METHODOLOGY. WHERE THERE IS A LACK OF VSOE OF FAIR VALUE AMONG THE
     ARRANGEMENT ELEMENTS, SOP 97-2 PROHIBITS SEPARATION OF THE TOTAL
     ARRANGEMENT FEE FOR RECOGNITION PURPOSES. ABSENT A COMPELLING ARGUMENT
     UNDER GAAP AND RULE 5-03(B)(1) OF REGULATION S-X THAT SUPPORTS ALLOCATING
     THE ARRANGEMENT FEE IN THE INCOME STATEMENT, YOU SHOULD AMEND YOUR
     PRESENTATION TO INCLUDE SEPARATE REVENUE, AND RELATED COST OF REVENUE, LINE
     ITEMS FOR BUNDLED ARRANGEMENTS THAT ARE NOT SEPARABLE BECAUSE OF THE
     ABSENCE OF VSOE FOR THE UNDELIVERED PCS ELEMENT. YOU SHOULD ALSO INCLUDE A
     FOOTNOTE DESCRIPTION TO INFORM INVESTORS OF THE NATURE OF THE ADDITIONAL
     LINE ITEM. PLEASE ALSO DESCRIBE TO US OTHER POSSIBLE ALLOCATION
     METHODOLOGIES FOR INCOME STATEMENT PURPOSES THAT YOU CONSIDERED BUT
     REJECTED.

     We allocate revenues related to bundled revenue arrangements that are not
     separable for recognition purposes because there is a lack of VSOE to the
     relevant line items on our consolidated statement of operations for
     classification purposes. These line items are: software license revenues,
     maintenance revenues and professional services revenues. Our method for
     allocating these revenues between the various revenue line items for
     classification purposes is described in more detail below. In making the
     determination as to the presentation of this revenue in the consolidated
     statement of operations, we considered Rule 5-03(b) (1) of Regulation S-X,
     which states:

          "Net sales and gross revenues. State separately: (a) Net sales of
          tangible products (gross sales less discounts, returns and
          allowances), (b) operating revenues of



          public utilities or others; (c) income from rentals; (d) revenues from
          services; and (e) other revenues."

     We believe Rule 5-03 (b) (1) of Regulation S-X has a requirement to
     separately disclose products (software license fees) and services revenue
     (maintenance fees and professional services fees). In addition, we
     considered the guidance in "Software Revenue Recognition, An Analysis of
     SOP 97-2 and Related Guidance, Second Edition" published by KPMG LLP,
     Paragraph 8.038 (please note the last sentence):

          KPMG - 8.038 Consistent with our views described above with respect to
          contract accounting arrangements, if the vendor does not have VSOE of
          fair value for PCS, we believe that the vendor generally would not
          separate the license revenue from the PCS revenue and, accordingly,
          the revenue would be included within one line on the face of the
          income statement (e.g., license and service revenue or service
          revenue). If material, it may be appropriate for a software vendor to
          present such revenues as a separate line item on the income statement
          (e.g., license and service revenue from short-term time-based
          licensing arrangements) or to separately disclose such revenues in the
          notes to the financial statements. However, in some situations it may
          be acceptable for the vendor to apply an appropriate systematic and
          rational method to separate the license and PCS revenue on the face of
          the income statement, provided that the method used is consistently
          applied and clearly disclosed.

     We believe we have the ability to make reasonable estimates of the fair
     value of the individual elements in our bundled arrangements and we have a
     systematic and rational method to allocate such revenues to the appropriate
     line items for the purpose of income statement presentation. In addition,
     we believe separation provides the users of our financials statements
     important information to interpret our financial results.

     We follow the revenue recognition guidance in SOP 97-2 (as amended by SOP
     98-9) and other interpretative guidance (e.g. TPAs referenced in this
     document) for our software arrangements. Once we have determined when and
     how revenue should be recognized for our software arrangements, we consider
     the income statement presentation guidance of Rule 5-03(b) (1) of
     Regulation S-X. To comply with this rule, we separate the total arrangement
     fee based upon a systematic and rational method. We separate the total
     arrangement fee among the deliverables within the arrangement based upon
     our best estimate of fair value of the undelivered elements using the
     residual method where we allocate revenue to professional services,
     maintenance (PCS) and the remaining portion of the fee is classified as
     license revenues. We determined fair value by using VSOE of fair value for
     similar elements.

     Following are three groups of bundled revenue arrangements that are not
     separable because there is a lack of VSOE of fair value among the
     arrangement elements.



     -    The majority of the arrangements that are not separable because there
          is a lack of VSOE involve term licenses (either stand alone or
          combined with perpetual licenses). This is because we lack VSOE of
          fair value for post-contract customer support ("PCS") services in term
          licenses. While we have VSOE of fair value for PCS services in
          perpetual licenses, we cannot use such evidence to establish VSOE of
          fair value for PCS services in term licenses (per TPA 5100.68). We
          recognize revenue for these arrangements ratably over the term of the
          arrangement. For presentation purposes, we consider our VSOE of fair
          value of PCS for perpetual licenses (PCS renewals based on a fixed
          percentage of the sales price) as our best estimate of the fair value
          of PCS associated with term licenses. We use this estimate for
          allocating revenue between PCS and license revenues, where the
          remaining portion of the fee is classified as license revenue.

     To a lesser extent:

     -    We have arrangements that include a product that has a different VSOE
          of fair value for PCS than all of our other products. VSOE of fair
          value of PCS is a fixed percentage of net license fee for all of our
          products except one particular product for which VSOE of fair value of
          PCS is a higher percentage of the net license fee. If this product is
          bundled with other products, we are not able to establish VSOE of fair
          value of the PCS because we do not have VSOE of fair value of software
          license fees. We recognize these arrangements ratably over the PCS
          term. For presentation purposes, we allocate the arrangement
          consideration between the products with different PCS rates by
          allocating any discount percentage proportionately. Then, we apply our
          VSOE of fair value PCS rates to such allocation of the arrangement to
          calculate our best estimate of fair value for allocating revenue
          between PCS fees and license fees, where the remaining portion of the
          fee is recognized as license revenue. Following is an example of the
          allocation for presentation purposes:



                                                       Product A   Product B
                                                       ---------   ---------
                                                             
Net Price, after allocating discount proportionately       30          70
PCS VSOE %                                                 25%         18%
                                                         ----        ----
Allocated to PCS Fees                                     7.5        12.6
Allocated to License Fees                                22.5        57.4


     -    We also have software arrangements combined with professional services
          where it is not possible to reasonably estimate the hours to complete
          the professional services portion of the arrangement. While the
          contracts governing these arrangements typically provide for time and
          materials billing, we have a history of only charging the estimated
          fee provided to the customer (i.e. in substance, these are fixed fee
          arrangements). The professional services included in these
          arrangements do not involve significant production, modification, or
          customization of the software and are not considered essential to the
          functionality of the software. We have established VSOE of fair value
          for professional services based on the hourly and daily prices charged
          when such services are sold



          separately. Therefore, we generally determine the VSOE of fair value
          of professional services by multiplying these hourly rates by the
          estimated number of hours required to complete the professional
          services. In situations where we can not reasonably estimate the
          number of hours we have concluded that VSOE of fair value of the
          professional services does not exist. Accordingly, we recognize
          revenue for these arrangements over the period in which the
          professional services are expected to be performed, on a straight-line
          basis, in accordance with paragraph 67 of SOP 97-2. For presentation
          purposes, we use our VSOE of fair value for professional services
          (hourly or daily rates when sold separately) multiplied by the actual
          hours incurred to date as our best estimate of fair value for
          allocating revenue in these arrangements between professional services
          revenues and the remaining portion of the fee is classified as license
          revenue.

     We believe, based upon Rule 5-03 (b) (1) of Regulation S-X, it is required
     to allocate revenues between product and services revenues. Accordingly, we
     believe it is acceptable to make such allocation based on our best estimate
     of the fair value of the undelivered elements in the arrangement using the
     residual method for income statement presentation purposes. This
     classification provides the users of our financials statements important
     information to interpret our financial results. We did not consider
     alternative allocation methodologies.

     We will expand our disclosures in future filings to discuss our policy and
     methodology regarding the income statement presentation of bundled revenue
     arrangements that are not separable for recognition purposes because there
     is a lack of VSOE of fair value among the arrangement elements. The
     following is an example of our expanded disclosure.

          Software license fees - The Company's software license agreements
          provide its customers with a right to use its software perpetually
          (perpetual licenses) or during a defined term (term licenses).
          Perpetual license fee revenue is recognized using the residual method,
          under which the fair value, based on vendor specific objective
          evidence ("VSOE"), of all undelivered elements of the agreement (e.g.,
          maintenance and professional services) is deferred. VSOE is based on
          rates charged for maintenance and professional services when sold
          separately. The remaining portion of the fee, net of discretionary
          discounts (the residual), is recognized as license fee revenue upon
          delivery of the products, provided that no significant obligations
          remain and collection of the related receivable is deemed probable.

          For revenue arrangements that are not separable because there is a
          lack of VSOE of fair value into the various arrangement elements, the
          Company recognizes the license fee revenue on a ratable basis over the
          maintenance term or over the period in which the services are expected
          to be performed. However, for income statement presentation purposes,
          we allocate revenue between professional



          services fees, maintenance fees and licenses fees based on our best
          estimate of the fair value of the undelivered elements using the
          residual method.

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

REVENUE RECOGNITION, PAGE 47

3.   YOU DISCLOSE THAT REVENUE FROM TERM LICENSE ARRANGEMENTS AND ARRANGEMENTS
     IN WHICH YOU DO NOT HAVE VSOE OF UNDELIVERED ELEMENTS IS RECOGNIZED
     RATABLY. WE ALSO NOTE YOUR DISCLOSURE ON PAGE 35 AND IN YOUR FORM 8-K FILED
     ON APRIL 23, 2007 INDICATING THAT, DUE TO CHANGING AND MORE COMPLEX
     CONTRACTUAL TERMS, YOU EXPECT AN INCREASING PERCENTAGE OF ARRANGEMENTS
     WHERE RATABLE RECOGNITION WILL BE REQUIRED. PLEASE TELL US MORE ABOUT THESE
     ARRANGEMENTS THAT RESULT IN RATABLE RECOGNITION BY DESCRIBING THE LICENSING
     TRENDS AND SPECIFIC CONTRACTUAL TERMS THAT RESULT IN THE DEFERRAL OF
     REVENUE. AS PART OF YOUR RESPONSE, REFER TO THE AUTHORITATIVE GUIDANCE YOU
     RELIED UPON WHEN DETERMINING YOUR ACCOUNTING.

     Our response to comment two provides a description of three types of
     arrangements where we cannot establish VSOE of fair value for certain
     elements in our multiple element arrangements.

     We anticipate seeing more transactions that combine both term and perpetual
     licenses as an increasing number of companies in the software industry are
     offering these types of licenses. We believe our customers may demand more
     of these types of licenses in the future.

4.   WE NOTE THAT VSOE FOR MAINTENANCE AND PROFESSIONAL SERVICES IS BASED ON THE
     PRICE CHARGED WHEN THESE SERVICES ARE SOLD SEPARATELY. DESCRIBE THE PROCESS
     YOU USE TO EVALUATE THE VARIOUS FACTORS THAT EFFECT YOUR VSOE INCLUDING
     CUSTOMER TYPE AND PRICING FACTORS. FURTHER ADDRESS THE ISSUE THAT IF YOUR
     VSOE VARIES FROM CUSTOMER TO CUSTOMER, HOW YOU CAN REASONABLY ESTIMATE FAIR
     VALUE. IN THIS REGARD, WE NOTE YOUR DISCLOSURES ON PAGE 34 WHERE YOU
     INDICATE THAT BASED ON MARKET CONDITIONS, THE COMPANY PERIODICALLY CHANGES
     PRICING METHODOLOGIES FOR MAINTENANCE AND PROFESSIONAL SERVICES. TELL US
     HOW YOU FACTOR THESE CHANGES INTO YOUR ANALYSIS OF VSOE. SEE PARAGRAPH 10
     OF SOP 97-2.

     We evaluate VSOE of fair value for PCS and professional services based on
     the prices charged when these elements are sold separately. Our evaluation
     is based on GAAP including the following guidance from SOP 97-2 (including
     paragraphs 10 and 57), SOP 98-9, TPA 5100.52 and TPA 5100.55.

     When we evaluate our separate sales of PCS for purposes of establishing
     VSOE of fair value, we consider the type of customer, the type of software,
     contract types, pricing methodology, and estimate of the costs to provide
     maintenance. Based on



     these considerations we believe our separate sales of PCS are one
     homogeneous group, except for one product. We price our annual maintenance
     renewals for all of our software products based on a fixed percentage of
     the net license fee. This fixed percentage is consistent across all of our
     software products except for one product which has a higher fixed
     percentage. We review actual customer renewals and have concluded that
     these are sufficiently clustered within an appropriate range to establish
     VSOE of fair value of PCS. We believe our VSOE of PCS is very accurate, as
     we have found over 90% of our maintenance renewals, renew at the VSOE fixed
     percentage of the net license fee. This evaluation is consistent with the
     bell shaped curve methodology outlined in the "Software Revenue
     Recognition, An Analysis of SOP 97-2 and Related Guidance, Second Edition"
     published by KPMG LLP paragraph 5.008.

     When we evaluate our separate sales of professional services for purposes
     of establishing VSOE of professional services, we consider the type of
     services, type of customer, contract type, pricing methodology and an
     estimate of the costs to provide such professional services. Based on these
     considerations we have stratified our separate sales of professional
     services into two categories, product related services and general
     services. Our professional services are priced on a fixed hourly rate or
     daily rate. We review actual separate customer sales and have concluded
     that these are sufficiently clustered within an appropriate range to
     establish VSOE of professional services. We believe this evaluation is
     consistent, by analogy, with the bell shaped curve methodology outlined in
     "Software Revenue Recognition, An Analysis of SOP 97-2 and Related
     Guidance, Second Edition" published by KPMG LLP paragraph 5.008.

     We do consider price changes in our VSOE analysis. Because we have reviewed
     PCS renewals over many years and found them to establish VSOE (using the
     bell shaped curve methodology), we believe we have basis for VSOE of PCS
     when we change the fixed percentage of net license fee our customers will
     be charged for PCS. For professional services we have made only minor
     pricing changes and these have not resulted in a change in VSOE.

5.   WE FURTHER NOTE THAT WHILE YOUR STANDARD PERPETUAL LICENSES INCLUDE ONE
     YEAR OF MAINTENANCE, THE COMPANY ALSO ENTERS INTO MULTI-YEAR CONTRACTS THAT
     INCLUDE MAINTENANCE PERIODS RANGING FROM TWO TO FIVE YEARS. TELL US WHETHER
     YOU HAVE ESTABLISHED VSOE FOR MAINTENANCE INCLUDED IN MULTI-YEAR
     ARRANGEMENTS AND PLEASE DESCRIBE THE PROCESS USED TO ESTABLISH VSOE IN
     ARRANGEMENTS THAT INCLUDE INITIAL MAINTENANCE PERIODS OF TWO TO FIVE YEARS.
     FURTHER, IF YOU HAVE DETERMINED THAT THE COMPANY IS ABLE TO ESTABLISH VSOE
     FOR MAINTENANCE IN YOUR MULTI-YEAR ARRANGEMENTS, PLEASE TELL US HOW YOU
     DETERMINED THAT VSOE OF FAIR VALUE FOR SUCH SUPPORT IS CONSIDERED
     SUBSTANTIVE. IN THIS REGARD, AT A MINIMUM, PLEASE ADDRESS EACH OF THE
     CRITERIA IDENTIFIED IN TPA 5100.54, BY ANALOGY, AS INDICATORS THAT THE PCS
     RENEWAL RATES MAY NOT BE SUBSTANTIVE.



     As noted in our response to comment four above, we establish VSOE of fair
     value for PCS and professional services based on the prices charged when
     these elements are sold separately. We do not rely on contractual renewal
     rates as VSOE of fair value of PCS. Therefore, we do not believe that TPA
     5100.54 is applicable. As described in the response to comment four above
     we have established VSOE of fair value for an annual period of PCS on our
     perpetual licenses as a fixed percentage of the net license fee. In
     accordance with TPA 5100.55, for perpetual arrangements with multiple years
     of PCS, the annual VSOE of PCS is multiplied by the number of years for
     which PCS is included in the arrangement.

6.   WE NOTE YOUR DISCLOSURES ON PAGE 29 WHERE YOU INDICATE THAT FOR CERTAIN
     TRANSACTIONS THAT INCLUDE AN OPTION TO EXCHANGE OR SELECT PRODUCTS IN THE
     FUTURE, REVENUE IS DEFERRED AND RECOGNIZED OVER THE TERM OF THE AGREEMENT
     OR WHEN ALL REVENUE RECOGNITION CRITERIA HAVE BEEN MET. PLEASE PROVIDE MORE
     DETAILS REGARDING THE TERMS OF THESE ARRANGEMENTS. FOR INSTANCE, IF THE
     CUSTOMER CHOOSES THE "SELECT PRODUCT" OPTION ARE THEY ENTITLED TO USE THE
     PREVIOUSLY DELIVERED PRODUCT IN ADDITION TO THE SELECTED PRODUCT OR ARE
     THEY OBLIGATED TO RETURN THE ORIGINAL PRODUCT? ALSO, IF THEY ELECT TO USE
     THE "EXCHANGE" OPTION DOES THE EXCHANGE INCLUDE PRODUCTS WITH NO MORE THAN
     MINIMAL DIFFERENCES IN PRICE, FUNCTIONALITY OR FEATURES? PLEASE EXPLAIN AND
     TELL US HOW YOU APPLIED THE GUIDANCE IN PARAGRAPHS 39-51 OF SOP 97-2 IN
     ACCOUNTING FOR THESE ARRANGEMENTS.

     We have not entered into any of these types of arrangements for any year
     presented in the Statements of Operations. The most recent arrangements
     that may have been determined to fit this accounting description included
     extended payment terms that called into question whether or not the fee was
     fixed or determinable. Therefore, these arrangements were recognized as
     payments became due and payable. We will update future filings to remove
     this language unless we actually have transactions that require expanded
     descriptions.

NOTE 12. INCOME TAXES, PAGE 64

7.   WE NOTE THAT DURING THE QUARTER ENDED MARCH 31, 2007, THE COMPANY REDUCED
     ITS INCOME TAX PROVISION BY $26.6 MILLION FOR "CERTAIN ITEMS RELATED TO
     SETTLEMENTS OF PRIOR TAX MATTERS" WHICH INCLUDED AN AGREEMENT ON ISSUES
     THAT AFFECTED A "SPECIAL DEDUCTION AND CREDITS AFFORDED TO U.S. BASED
     TAXPAYERS THAT GENERATE INCOME FROM SALES TO FOREIGN CUSTOMERS." PLEASE
     EXPLAIN FURTHER WHAT YOU MEAN BY "SPECIAL DEDUCTION" AND DESCRIBE THE
     SETTLEMENT OF PRIOR YEAR TAX MATTERS THAT LEAD TO THE DECREASE IN THE
     CURRENT YEAR'S PROVISIONS. DOES PART OF THIS SETTLEMENT RELATE TO THE
     AMERICAN JOBS CREATION ACT OF 2004 OR TRANSFER PRICING ISSUES? WE FURTHER
     NOTE THAT THE COMPANY HAS RESERVES OF $11.6 MILLION AND $37.8 MILLION AT
     MARCH 31, 2007 AND MARCH 31, 2006, RESPECTIVELY FOR CERTAIN OPEN TAX
     MATTERS WITH VARIOUS SIGNIFICANT TAXING JURISDICTIONS FOR TAX YEARS 1996
     AND FORWARD.



     PLEASE EXPLAIN FURTHER THE ITEMS IMPACTING THESE RESERVES AND TELL US
     WHETHER THE SETTLEMENT OF CERTAIN ITEMS IN FISCAL 2007 AND THE
     CORRESPONDING REDUCTION IN THE RESERVE BALANCE IS RELATED TO THE $26.6
     MILLION REDUCTION IN YOUR TAX PROVISION.

     The "special deduction" refers to foreign sales commissions under the
     former foreign sales corporation (FSC) rules and the extraterritorial
     income exclusion (ETI), the replacement for the FSC. The Company received
     its Revenue Agent Report (RAR) on March 28, 2007 detailing particular items
     of adjustment by the IRS for tax years ended March 31, 2000 through March
     31, 2004. The Company accepted all but three of the adjustment items in
     this RAR; such items have been formally protested to the IRS appeals
     division. The Company considers these three items to have appropriate
     reserves under Statement of Financial Accounting Standards No. 5,
     "Accounting for Contingencies". The financial results of finalizing the IRS
     audit have been reflected as "settlement of prior year tax matters" during
     the quarter ended March 31, 2007 and amounted to $26.6 million. Items
     settled that specifically related to the FSC and ETI special deductions
     totaled $8.7 million. Items settled that specifically related to credits
     afforded to U.S. based taxpayers that generate income from sales to foreign
     customers totaled $10.2 million. Items settled regarding the proper
     character and timing of certain deductions amounted to $3.3 million. In
     addition, the aforementioned items settled had associated interest and
     state taxes totaling $4.4 million. None of this settlement relates to the
     American Jobs Creation Act of 2004 or transfer pricing issues.

     The Company's income tax reserves were $37.8 million at March 31, 2006.
     During fiscal 2007, the settlement of prior year tax matters comprised
     substantially all of the reserve reduction of $26.2 million to arrive at
     the income tax reserve balance of $11.6 million at March 31, 2007.
     Moreover, this reduction in the reserve balance is substantially all
     related to the $26.6 million reduction in the Company's income tax
     provision.

     The Company will modify future filings to describe the "special deductions"
     as FSC and ETI.
