NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
(Unaudited)

1.    Interim Condensed and Consolidated Financial Statements

        In the opinion of management, the accompanying unaudited interim consolidated condensed financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) for reporting on Form 10-Q. Accordingly, certain information and footnote disclosures required for complete financial statements are not included herein. It is suggested that these unaudited interim consolidated condensed financial statements be read in conjunction with the audited consolidated financial statements for the year ended June 30, 2002, which are contained in the Annual Report on 10-K of Aspen Technology, Inc. (the Company), as previously filed with the SEC. In the opinion of management, all adjustments (consisting of normal, recurring adjustments) considered necessary for a fair presentation of the financial position, results of operations, and cash flows at the dates and for the periods presented have been included. The consolidated condensed balance sheet presented as of June 30, 2002 has been derived from the consolidated financial statements that have been audited by the Company's independent public accountants. The results of operations for the three- and six-month periods ended December 31, 2002 are not necessarily indicative of the results to be expected for the full year.

        In November 2001, the Emerging Issues Task Force (EITF) released Issue No. 01-14, "Income Statement Characterization of Reimbursements Received for "Out-of-Pocket' Expenses Incurred". This requires that reimbursements received for out-of-pocket expenses be recorded as revenue and not as a reduction of expenses. Reimbursable out-of-pocket expenses totaling $4.9 million and $10.0 million in the three and six months ended December 31, 2002, and $5.1 million and $10.0 million in the three and six months ended December 31, 2001, respectively, have been classified as service and other revenue and cost of service and other.

        In August 2001, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets". This statement supersedes SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of", and the accounting and reporting provisions of Accounting Principles Board Opinion No. 30, "Reporting the Results of Operations—Reporting the Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions". Under this statement, one accounting model is required to be used for long-lived assets to be disposed of by sale, whether previously held and used or newly acquired. This statement broadens the presentation of discontinued operations to include more disposal transactions. Under the provisions of this statement, several long-lived assets were reviewed for impairment in association with the October 2002 restructuring plan, resulting in an impairment charge during the three months ended December 31, 2002.

2.    Short-term Investments

        Securities purchased to be held for indefinite periods of time, and not intended at the time of purchase to be held until maturity, are classified as available-for-sale securities. Securities classified as available-for-sale are required to be recorded at market value in the financial statements. Unrealized gains and losses have been accounted for as a separate component of stockholders' equity within accumulated other comprehensive loss. Realized investment gains and losses were not material in the three- or six- month periods ended December 31, 2002 and 2001. Investments held as of December 31, 2002 consisted of $3.1 million in U.S. corporate bonds. The Company does not use derivative financial instruments in its investment portfolio.

5



        Cash equivalents totaling $10.8 million were held by the bank as compensating balances for outstanding letters of credit as of December 31, 2002.

3.    Sale of Installments Receivable

        Installments receivable represent the present value of future payments related to the financing of noncancelable term and perpetual license agreements that provide for payment in installments over a one-to five-year period. A portion of each installment agreement is recognized as interest income in the accompanying consolidated condensed statements of operations. The interest rates utilized for the three and six months ended December 31, 2002 were 7.0% and 7.0% to 7.5%, respectively. In the three and six months ended December 31, 2001, the rates utilized were 7.0% and 7.0% to 8.0%, respectively.

        The Company has arrangements to sell its installments receivable to two financial institutions. These arrangements provide for the sale of up to a maximum of $160.0 million, subject to the approval by the institutions, to be outstanding at any one time. The Company sold, with limited recourse, certain of its installment contracts for aggregate proceeds of approximately $24.1 million and $32.6 million during the three and six months ended December 31, 2002, respectively. The financial institutions have certain recourse to the Company upon non-payment by the customer under the installments receivable. The amount of recourse is determined pursuant to the provisions of the Company's contracts with the financial institutions. Collections of these receivables reduce the Company's recourse obligations, as defined. Generally, no gain or loss is recognized on the sale of the receivables, due to the consistency of the discount rates used by the Company and the financial institutions.

        At December 31, 2002, the balance of the uncollected principal portion of all contracts sold was $138.5 million. The Company expects that there will be continued availability under the arrangements, as the collection of the sold receivables will reduce this outstanding balance and the maximum limits under the arrangements can be increased. The Company's potential recourse obligation related to these contracts is within the range of $6.8 million to $9.2 million. In addition, the Company is obligated to pay additional costs to the financial institutions in the event of default by the customer.

4.    Derivative Instruments and Hedging

        The Company follows the provisions of SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities." SFAS No. 133 requires that all derivatives, including foreign currency exchange contracts, be recognized on the balance sheet at fair value. Derivatives that are not hedges must be recorded at fair value through earnings. If a derivative is a hedge, depending on the nature of the hedge, changes in the fair value of the derivative are either offset against the change in fair value of assets, liabilities or firm commitments through earnings or recognized in other comprehensive income until the hedged item is recognized in earnings. The ineffective portion of a derivative's change in fair value is to be immediately recognized in earnings.

        Forward foreign exchange contracts are used primarily by the Company to hedge certain balance sheet exposures resulting from changes in foreign currency exchange rates. Such exposures primarily result from portions of the Company's assets that are denominated in currencies other than the U.S. dollar, primarily the British Pound, the Japanese Yen and the Euro. These foreign exchange contracts are entered into to hedge recorded installments receivable made in the normal course of business, and accordingly, are not speculative in nature. As part of its overall strategy to manage the level of exposure to the risk of foreign currency exchange rate fluctuations, the Company hedges the majority of its installments receivable denominated in foreign currencies.

        At December 31, 2002, the Company had effectively hedged $7.9 million of installments receivable denominated in foreign currency. The Company does not hold or transact in financial instruments for purposes other than risk management. The gross value of the long-term installments receivable that were denominated in foreign currency was $25.0 million at December 31, 2002. The December 2002

6



installments receivable mature through January 2007. There have been no material gains or losses recorded relating to hedge contracts for the periods presented.

        The Company records its foreign currency exchange contracts at fair value in its consolidated balance sheet and the related gains or losses on these hedge contracts are recognized in earnings. Gains and losses resulting from the impact of currency exchange rate movements on forward foreign exchange contracts are designated to offset certain accounts or installments receivable and are recognized as other income or expense in the period in which the exchange rates change and offset the foreign currency losses and gains on the underlying exposures being hedged. A small portion of the forward foreign currency exchange contract is designated to hedge the future interest income of the related receivables. The gains and losses resulting from the impact of currency rate movements on forward currency exchange contracts are recognized in other comprehensive income for this portion of the hedge.

        The following table provides information about the Company's foreign currency derivative financial instruments outstanding as of December 31, 2002. The information is provided in U.S. dollar amounts, as presented in the Company's consolidated condensed financial statements. The table presents the notional amount (at contract exchange rates), the estimated fair value and the weighted average contractual foreign currency rates (in thousands, except average contract rates):

 
  Notional
Amount

  Estimated
Fair value

  Average
Contract Rate

Euro   $ 3,289   $ 3,570   1.08
Japanese Yen     2,143     1,981   118.88
British Pound Sterling     1,981     2,132   0.67
Swiss Franc     456     493   1.50
   
 
   
    $ 7,869   $ 8,176    
   
 
   

*
The estimated fair value is based on the estimated amount at which the contracts could be settled based on the spot rates as of December 31, 2002. The market risk associated with these instruments resulting from currency exchange rate movements is expected to offset the market risk of the underlying installments being hedged. The credit risk is that the Company's banking counterparties may be unable to meet the terms of the agreements. The Company minimizes such risk by limiting its counterparties to major financial institutions. In addition, the potential risk of loss with any one party resulting from this type of credit risk is monitored. Management does not expect any loss as a result of default by other parties. However, there can be no assurances that the Company will be able to mitigate market and credit risks described above.

5.    Net Income (Loss) Per Common Share

        Basic income (loss) per common share is calculated by dividing net income (loss) applicable to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings (loss) per common share reflect the dilutive effect, if any, of potential common shares.

7.    Goodwill Adjustments and Impairment Charge

        During the three months ended December 31, 2002, the Company made adjustments to the purchase price allocation associated with the Hyprotech acquisition, which was completed in May 2002. These consisted of various adjustments to the opening balance sheet to accrue for certain obligations and contingencies and to write-off certain assets. These adjustments resulted in a $1.8 million increase to goodwill. The Company intends to make final adjustments to the purchase price, as required, through May 2003.

        The Company follows the provisions of SFAS No. 142, "Goodwill and Other Intangible Assets". In October 2002, management determined that the goodwill should be tested for impairment as a result of management's lowered revenue expectations and the overall decline in the Company's market value. An independent third party valued the Company's three reporting units, license, consulting services, and maintenance and training. The valuation was based on an income approach, using a five-year present value calculation of income, and a market approach, using comparable company valuations. Based on this analysis, it was determined that the full values of the goodwill associated with the license reporting unit and consulting services reporting unit were impaired. It was also determined that the fair value of the maintenance and training reporting unit exceeded its carrying value, resulting in no impairment of its goodwill. This amounted to a $74.7 million aggregate impairment charge.

8.    Restructuring and Other Charges

    (a) Q2 FY03

        The restructuring and other charges, totaling $60.5 million in the accompanying consolidated condensed statements of operations for the three and six months ended December 31, 2002, consist of $55.6 million of charges associated with the Company's October 2002 restructuring plan, and $4.9 million of accrued legal costs related to the ongoing FTC investigation as discussed in Note 10.

        In October 2002, the Company initiated a plan to further reduce operating expenses in response to first quarter revenue results that were below expectations and general economic uncertainties. In addition, the Company revised its revenue expectations for the remainder of the fiscal year and beyond, primarily related to the Company's manufacturing / supply chain product line, which has been effected the most by the current economic conditions. The plan to reduce operating expenses resulted in headcount reductions, consolidation of facilities, cancellation of certain internal capital projects and discontinuation of development and support for certain non-critical products. As a result of the discontinuation of development and support for certain products, coupled with the revised revenue expectations, certain long-lived assets were reviewed and determined to be impaired in accordance with SFAS No. 144. These actions resulted in an aggregate restructuring charge of $55.6 million. As of December 31, 2002, there was $12.0 million remaining in accrued expenses relating to the remaining severance obligations and lease payments. During the three months ended December 31, 2002, the following activity was recorded (in thousands):

The Company expects that the remaining obligations will be paid-out by December 2010.

Closedown/consolidation of facilities:    Approximately $8.7 million of the restructuring charge relates to the termination of facility leases and other lease related costs. The facility leases had remaining terms ranging from several months to eight years. The amount accrued is an estimate of the remaining obligation under the lease or actual costs to buy-out leases, reduced by expected income from the sublease of the underlying properties.

Employee severance, benefits and related costs:    Approximately $8.2 million of the restructuring charge relates to the reduction in headcount. Approximately 400 employees, or 20% of the workforce, were eliminated under the restructuring plan implemented by management. All geographic regions and business units were affected, including services, sales and marketing, research and development, and general and administrative.

Impairment/write-off of assets:    Approximately $38.7 million of the restructuring charge relates to charges associated with long-lived assets that were reviewed for impairment under the provisions of SFAS No. 144 and were either written-down to fair value or written-off due to the fact that they will no longer be utilized. The resulting charges include:

    A $23.6 million impairment charge related to the intellectual property purchased from Accenture in February 2002. The fair value of this asset was determined by forecasting the future net cash flows associated with the asset and then was compared to its carrying value. This intellectual property is used primarily in the development of manufacturing / supply chain software products, within the Company's license line of business. As noted above, the revenue expectations for the manufacturing / supply chain product line were significantly reduced by management, which prompted the review for impairment.

    $13.2 million in impairment charges related to acquired technology, computer software development costs and purchased software. These assets were considered to be impaired because they will either no longer be used or their carrying values were in excess of their fair values. The assets that will no longer be used were identified by management's decisions to either discontinue future development efforts associated with certain products or discontinue internal capital projects. The fair values of those assets that had carrying values in excess of their fair values, were determined by forecasting the future net cash flows associated with the products. All of these assets were part of the license line of business.

    A $1.9 million impairment charge related to assets and liabilities associated with certain products of which the Company is divesting itself. These assets have historically been considered to be part of the license line of business. As part of the cost reductions, management decided that the Company would no longer devote resources to the development or support of these products. The fair value of the related assets was determined from letters of intent to purchase the intellectual property.

    (b) Q4 FY02

        In the fourth quarter of fiscal 2002, the Company initiated a plan to reduce its operating expenses and to restructure operations around its two primary product lines, engineering software and manufacturing/supply chain software. The Company reduced worldwide headcount by approximately 10% or 200 employees, closed-down and consolidated facilities, and disposed of certain assets, resulting in an aggregate restructuring charge of $14.4 million. As of December 31, 2002, there was $7.6 million remaining in accrued expenses relating to the remaining severance obligations and lease payments. During the three months ended December 31, 2002, the following activity was recorded:

    (c) Q1 FY02

        During the first quarter of fiscal 2002, in light of further economic uncertainties, Company management made a decision to adjust its business plan by further reducing spending. This change in business plan consisted of a reduction in worldwide headcount of approximately 5% of the workforce and a reduction of certain future discretionary expenses. As a result of these measures, the Company recorded a restructuring charge of $2.6 million, primarily for severance, for the quarter ended September 30, 2001. As of December 31, 2002, all obligations had been paid-out. During the three months ended December 31, 2002, the following activity was recorded:

    (d) Q4 FY01

        In the third quarter of fiscal 2001, the revenues realized by the Company were below the Company's expectations as customers delayed spending in the widespread slowdown in information technology spending and the deferral of late-quarter purchasing decisions. At that time, the Company also reduced its revenue expectations for the fourth quarter of fiscal year 2001 and for the fiscal year 2002. Based on the reduced revenue expectations, Company management evaluated the business plan and made significant changes, resulting in a restructuring plan for the Company's operations. This restructuring plan included a reduction in headcount, a substantial decrease in discretionary spending and a sharpening of the Company's e-business focus to emphasize its marketplace solutions. The restructuring plan resulted in a pretax charge totaling $7.0 million. As of December 31, 2002, there was $0.9 million remaining in accrued expenses relating to the restructuring. During the three months ended December 31, 2002, the following activity was recorded:

 
  Closedown/

The Company expects that the remaining obligations will be paid-out by March 2008.

11



    (e) Q4 FY99

        In the fourth quarter of fiscal 1999, the Company undertook certain actions to restructure its business. The restructuring resulted from a lower than expected level of license revenues which adversely affected fiscal year 1999 operating results. The license revenue shortfall resulted primarily from delayed decision making driven by economic difficulties among customers in certain of the Company's core vertical markets. The restructuring plan resulted in a pre-tax restructuring charge totaling $17.9 million. As of December 31, 2002, there was $0.6 million remaining in the accrued expenses relating to the restructuring. During the three months ended December 31, 2002, the following activity was recorded:

 
  Closedown/
Consolidation
of Facilities

Accrued expenses, September 30, 2002   $ 274
Net sub-lease receipts (lease payments)     324
   
Accrued expenses, December 31, 2002   $ 598
   

The Company expects that the remaining obligations will be paid-out by December 2004.

9.    Strategic Alliance

        On February 8, 2002 the Company entered into a strategic alliance with Accenture, focused on creating solutions for manufacturing and supply chain execution by chemical and petroleum manufacturers. Under the alliance, the Company will pay $29.6 million for intellectual property and up to $7.4 million for services. The $29.6 million intellectual property obligation was partially settled with the payment of $18.5 million in common stock on June 9, 2002. In August 2002, the alliance agreements were amended to provide a payment schedule for the remaining $11.1 million. Under this revised payment schedule, the Company made cash payments totaling $3.1 million in the six months ended December 31, 2002 and will make the remaining payments in installments of cash, due through July 2003. In addition, the unpaid balance of this obligation accrues interest at a rate of 1.5% per month and, as of December 31, 2002, was secured by a pledge of the Company's patents and software. On January 30, 2003, the agreement was modified so that the unpaid balance of the obligation will be secured by a pledge of certain installments receivable not sold to financial institutions. As discussed in Note 8(a), during the three months ended December 31, 2002 it was determined that the intellectual property was impaired, which resulted in an impairment charge of $23.6 million.

        Beginning July 1, 2002, the Company is obligated to pay Accenture a royalty on sales of certain software products over a four-year period. During the three and six months ended December 31, 2002, the Company accrued $0.3 million and $0.5 million, respectively, associated with this royalty obligation.

10.  Commitments and Contingencies

    (a) FTC investigation

        By letter of June 7, 2002, the FTC informed the Company that it was conducting an investigation into the competitive effects of the Company's recent acquisition of Hyprotech. The Company completed production of all requested documents in January 2003, is currently complying with deposition requests and expects to conclude its presentation to the FTC of its market analysis and supporting arguments for the acquisition in February 2003. The FTC may determine to challenge the acquisition through an administrative civil complaint seeking to declare the acquisition in violation of Section 7 of the Clayton Act or Section 5 of the FTC Act. If the FTC were to prevail in that challenge, it could seek to impose a wide variety of remedies, some of which may have a material adverse effect on the Company's ability to continue to operate under its current business plans. These potential

12


remedies include divestiture of Hyprotech, as well as mandatory licensing of Hyprotech software products and the Company's other engineering software products to one or more of its competitors. The Company continues to cooperate fully with the FTC. During the quarter ended December 31, 2002, the Company provided $4.9 million for estimated legal fees associated with the FTC investigation.

    (b) Litigation

        On May 31, 2002, the Company acquired the capital stock of Hyprotech from AEA Technology plc. AEA Technology is engaged in arbitration proceedings in England over a contract dispute with KBC Advanced Technologies PLC, an English technology and consulting services company ("KBC"). The dispute remains in arbitration and concerns the characterization of certain technology for purposes of calculating royalties, plus other contractual rights, with respect to Hysys.Refinery. Hysys.Refinery was retained by AEA Technology with support for Hysys.Refinery to be provided by Hyprotech pursuant to a contract with AEA Technology. The Company indemnified AEA under the Sale and Purchase Agreement between AEA Technology plc and the Company dated May 10, 2002 against any costs, damages or expenses in respect of a claim brought by KBC alleging damages due to AEA's i) failure to comply with its contractual obligations after the acquisition, ii) breach of non-competition clauses with respect to activities occurring after the acquisition, iii) breach of certain obligations to KBC under its agreement by virtue of the acquisition, or iv) execution of the acquisition agreement.

        On September 11, 2002, the Company and Hyprotech were sued by KBC in state district court in Houston, Texas on issues related to the technology subject to review in the arbitration proceeding. KBC has requested actual and exemplary damages, costs and interest. The Company believes the causes of action to be without merit and will defend the case vigorously. The Company has filed a counterclaim against KBC requesting actual and punitive damages and attorney fees.

11.  Segment Information

        SFAS No. 131, "Disclosures about Segments of an Enterprise and Related Information", establishes standards for reporting information about operating segments in companies' financial statements. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. The Company's chief operating decision maker is the Chief Executive Officer of the Company.

        The Company is organized geographically and by line of business. The Company has three major lines of business operating segments: license, consulting services and maintenance and training. The Company also evaluates certain subsets of business segments by vertical industries as well as by product categories. While the Executive Management Committee evaluates results in a number of different ways, the line of business management structure is the primary basis for which it assesses financial performance and allocates resources.

        The accounting policies of the line of business operating segments are the same as those described in the Company's Annual Report on Form 10-K for the fiscal year ended June 30, 2002. The Company does not track assets or capital expenditures by operating segments. Consequently, it is not practical to

13



show assets, capital expenditures, depreciation or amortization by operating segments. The following table presents a summary of operating segments (in thousands):

12.  Accounting Policies and Recent Accounting Pronouncements

        During the three months ended December 31, 2002 the Company adopted a policy to accrue future legal fees associated with outstanding litigation. Previously, the Company had not encountered litigation that resulted in material defense costs, and thus the Company had no established policy. Liabilities for loss contingencies arising from claims, assessments, litigation and other sources are

14



recorded when it is probable that a liability has been incurred and the amount of the claim assessment or damages can be reasonably estimated.

        In April 2002, the FASB issued SFAS No. 145, "Rescission of FASB Statements SFAS Nos. 4, 44 and 64, Amendment of FASB Statement No. 13 and Technical Corrections". SFAS No. 145 rescinds Statement No. 4, "Reporting Gains and Losses from Extinguishments of Debt", and an amendment of that Statement, FASB Statement No. 64, "Extinguishments of Debt Made to Satisfy Sinking-Fund Requirements". SFAS No. 145 also rescinds FASB Statement No. 44, "Accounting for Intangible Assets of Motor Carriers". SFAS No. 145 amends FASB Statement No. 13, "Accounting for Leases", to eliminate an inconsistency between the required accounting for sale-leaseback transactions and the required accounting for certain lease modifications that have economic effects that are similar to sale leaseback transactions. SFAS No. 145 also amends other existing authoritative pronouncements to make various technical corrections, clarify meanings, or describe their applicability under changed conditions. The provision of SFAS No. 145 related to the rescission of Statement No. 4 shall be applied in fiscal years beginning after May 15, 2002. The provisions of SFAS No. 145 related to Statement No. 13 should be applied for transactions occurring after May 15, 2002. Early application of the provisions of this Statement is encouraged. The adoption of SFAS No. 145 did not have a significant impact on consolidated results of operations, financial position or cash flows.

        In June 2002, the FASB issued SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities." This statement supersedes EITF No. 94-3, "Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity." Under this statement, a liability or a cost associated with a disposal or exit activity is recognized at fair value when the liability is incurred rather than at the date of an entity's commitment to an exit plan as required under EITF 94-3. The provisions of this statement are effective for exit or disposal activities that are initiated after December 31, 2002, with early adoption permitted. As the Company's October 2002 restructuring plan was undertaken prior to December 31, 2002, the previous guidance as set forth in EITF 94-3 was followed.

        In November 2002, the FASB issued FASB Interpretation No. 45, "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others" (FIN 45). This interpretation elaborates on the disclosures to be made by a guarantor in its interim and annual financial statements about its obligations under certain guarantees that it has issued. It also clarifies that a guarantor is required to recognize, at the inception of a guarantee, a liability for the fair value of the obligation undertaken in issuing the guarantee. The initial recognition and initial measurement provisions of FIN 45 are applicable on a prospective basis to guarantees issued or modified after December 31, 2002. The disclosure requirements of FIN 45 are effective for financial statements of interim or annual periods ending after December 15, 2002. The Company is currently evaluating the impact that the adoption of the recognition provisions of FIN 45 will have on its financial statements.

13.  Subsequent events

        In January 2003, the Company executed a Loan Arrangement with Silicon Valley Bank. This arrangement provides a line of credit of up to the lesser of (i) $15.0 million or (ii) 70% of eligible domestic receivables, and a line of credit of up to the lesser of (i) $10.0 million or (ii) 80% of eligible foreign receivables. The lines of credit bear interest at the bank's prime rate (4.25% at December 31, 2002) plus 1/2%, which may be reduced to the bank's prime rate upon the achievement of two consecutive quarters of net income. The Company is required to maintain a $4.0 million compensating cash balance with the bank, or be subject to an unused line fee and collateral handling fees. The lines of credit will initially be collateralized by nearly all of the assets of the Company, and upon achieving certain net income targets, the collateral will be reduced to a lien on the accounts receivable. The

15



Company is required to meet certain financial covenants, including minimum tangible net worth, minimum cash balances and an adjusted quick ratio. The Loan Arrangement expires in January 2005.

        On January 31, 2003, the Company completed the sale of the assets and liabilities associated with the Aspen Metals products. These products were originally acquired in the December 2000 acquisition of Broner Systems. The Company will receive an aggregate of £300,000 ($494,000 as of January 31, 2003), to be paid in four semi-annual installments from June 2003 to January 2005.

Item 2.    Management's Discussion and Analysis of Financial Condition and Results of Operations

        THE FOLLOWING DISCUSSION AND ANALYSIS OF OUR FINANCIAL CONDITION AND RESULTS OF OPERATIONS SHOULD BE READ IN CONJUNCTION WITH OUR CONSOLIDATED FINANCIAL STATEMENTS AND THE RELATED NOTES APPEARING ELSEWHERE IN THIS QUARTERLY REPORT ON FORM 10-Q AND IN OUR ANNUAL REPORT ON FORM 10-K FOR THE FISCAL YEAR ENDED JUNE 30, 2002. THIS DISCUSSION AND ANALYSIS CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS, UNCERTAINTIES AND ASSUMPTIONS. OUR ACTUAL RESULTS MAY DIFFER MATERIALLY FROM THOSE ANTICIPATED IN THESE FORWARD-LOOKING STATEMENTS AS A RESULT OF A NUMBER OF FACTORS, INCLUDING THOSE SET FORTH UNDER "FACTORS THAT MAY AFFECT FUTURE RESULTS AND THE TRADING PRICE OF OUR COMMON STOCK" AND ELSEWHERE IN THIS QUARTERLY REPORT.

Overview

        Since our founding in 1981, we have developed and marketed software and services to companies in the process industries. In addition to internally generated growth, we have acquired a number of businesses, including Hyprotech in the fourth quarter of fiscal 2002.

        We acquired Hyprotech in a transaction accounted for as a purchase. Our operating results include the operating results of these acquisitions only for periods subsequent to their respective dates of acquisition.

        We typically license our engineering solutions for terms of three to five years and license our manufacturing/supply chain solutions for terms of 99 years.

        Software license revenues, including license renewals, consists principally of revenues earned under fixed-term and perpetual software license agreements and is generally recognized upon shipment of the software if collection of the resulting receivable is probable, the fee is fixed or determinable, and vendor-specific objective evidence, or VSOE, of fair value exists for all undelivered elements. We determine VSOE based upon the price charged when the same element is sold separately. Maintenance and support VSOE represents a consistent percentage of the license fees charged to customers. Consulting services VSOE represents standard rates, which we charge our customers when we sell our consulting services separately. For an element not yet being sold separately, VSOE represents the price established by management having the relevant authority when it is probable that the price, once established, will not change before the separate introduction of the element into the marketplace. Revenues under license arrangements, which may include several different software products and services sold together, are allocated to each element based on the residual method in accordance with SOP 98-9, "Software Revenue Recognition, with Respect to Certain Transactions." Under the residual method, the fair value of the undelivered elements is deferred and subsequently recognized when earned. We have established sufficient VSOE for professional services, training and maintenance and support services. Accordingly, software license revenues are recognized under the residual method in arrangements in which software is licensed with professional services, training and maintenance and support services. We use installment contracts 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.

        Maintenance and support services revenues are recognized ratably over the life of the maintenance and support contract period. Maintenance and support services include telephone support and unspecified rights to product upgrades and enhancements. These services are typically sold for a one-year term and are sold either as part of a multiple element arrangement with software licenses or are sold independently at time of renewal. We do not provide specified upgrades to our customers in connection with the licensing of our software products.

17



        Service revenues from fixed-price contracts are recognized using the percentage-of-completion method, measured by the percentage of costs (primarily labor) incurred to date as compared to the estimated total costs (primarily labor) for each contract. When a loss is anticipated on a contract, the full amount thereof is provided currently. Service revenues from time-and-expense contracts and consulting and training revenues are recognized as the related services are performed. Services that have been performed but for which billings have not been made are recorded as unbilled services, and billings that have been recorded before the services have been performed are recorded as unearned revenue in the accompanying consolidated balance sheets.

        We license our software in U.S. dollars and several foreign currencies. We hedge material foreign currency-denominated installments receivable with specific hedge contracts in amounts equal to those installments receivable. Historically, we experience minor foreign currency exchange gains or losses due to foreign exchange rate fluctuations, the impact of which have not been material in periods prior to the fourth quarter of fiscal 2002. During the fourth quarter of fiscal 2002, the U.S. Dollar weakened against European currencies, and we experienced foreign currency exchange losses primarily due to ineffective hedging of accounts receivable of our foreign subsidiaries, in particular Hyprotech and its subsidiaries, that were denominated in currencies other than the local functional currencies. We do not expect fluctuations in foreign currencies to have a significant impact on either our revenues or our expenses in the foreseeable future.

    Reclassification of Prior Period Amounts

        We adopted EITF Issue No. 01-14, "Income Statement Characterization of Reimbursements Received for "Out-of-Pocket' Expenses Incurred", in the three months ended March 31, 2002. This requires that reimbursements received for out-of-pocket expenses be recorded as revenue and not as a reduction of expenses. Reimbursable out-of-pocket expenses totaling $4.9 million and $10.0 million in the three and six months ended December 31, 2002 and $5.1 million and $10.0 million in the three and six months ended December 31, 2001, have been classified as service and other revenue and cost of service and other.

    Significant Events—Quarter Ended December 31, 2002

        In October 2002, we determined that the goodwill should be tested for impairment as a result of lowered revenue expectations and the overall decline in our market value. An independent third party valued our three business operating units, license, consulting services, and maintenance and training. The valuation was based on an income approach, using a five-year present value calculation of income, and a market approach, using comparable company valuations. Based on this analysis, it was determined that the full values of the goodwill associated with the license unit and consulting services unit were impaired. It was also determined that the fair value of the maintenance and training reporting unit exceeded its carrying value, resulting in no impairment of its goodwill. This amounted to a $74.7 million aggregate impairment charge, recorded in the accompanying consolidated condensed statements of operations.

        The restructuring and other charges, totaling $60.5 million in the accompanying consolidated condensed statements of operations for the three and six months ended December 31, 2002, consist of $55.6 million of charges associated with our October 2002 restructuring plan, and $4.9 million of accrued legal costs, related to the FTC investigation into our acquisition of Hyprotech.

        In October 2002, we initiated a plan to further reduce operating expenses in response to first quarter revenue results that were below our expectations and to general economic uncertainties. In addition, we revised our revenue expectations for the remainder of the fiscal year and beyond, primarily related to our manufacturing / supply chain product line, which has been effected the most by the current economic conditions. The plan to reduce operating expenses resulted in headcount reductions,

18



consolidation of facilities, cancellation of certain internal capital projects and discontinuation of development and support for certain non-critical products. As a result of the discontinuation of development and support for certain products, coupled with the revised revenue expectations, certain long-lived assets were reviewed and determined to be impaired in accordance with SFAS No. 144. These actions resulted in an aggregate restructuring charge of $55.6 million. As of December 31, 2002, there was $12.0 million remaining in accrued expenses relating to the remaining severance obligations and lease payments. During the three months ended December 31, 2002, the following activity was recorded (in thousands):

Closedown/consolidation of facilities:    Approximately $8.7 million of the restructuring charge relates to the termination of facility leases and other lease related costs. The facility leases had remaining terms ranging from several months to eight years. The amount accrued is an estimate of the remaining obligation under the lease or actual costs to buy-out leases, reduced by expected income from the sublease of the underlying properties.

Employee severance, benefits and related costs:    Approximately $8.2 million of the restructuring charge relates to the reduction in headcount. Approximately 400 employees, or 20% of the workforce, were eliminated under the restructuring plan. All geographic regions and business units were affected, including services, sales and marketing, research and development, and general and administrative.

Impairment/write-off of assets:    Approximately $38.7 million of the restructuring charge relates to charges associated with long-lived assets that were reviewed for impairment under the provisions of SFAS No. 144 and were either written-down to fair value or written-off due to the fact that they will no longer be utilized. The resulting charges include:

    A $23.6 million impairment charge related to the intellectual property purchased from Accenture in March 2002. The fair value of this asset was determined by forecasting the future net cash flows associated with the asset and was then compared to its carrying value. This intellectual property is used primarily in the development of manufacturing / supply chain software products, within our license line of business. As noted above, the revenue expectations for the manufacturing / supply chain product line were significantly reduced, which prompted the review for impairment.

    $13.2 million in impairment charges related to acquired technology, computer software development costs and purchased software. These assets were considered to be impaired because they will either no longer be used or their carrying values were in excess of their fair values. The assets that will no longer be used were identified by decisions to either discontinue future development efforts associated with certain products or discontinue internal capital projects. The fair values of those assets that had carrying values in excess of their fair values, were determined by forecasting the future net cash flows associated with the products. All of these assets were part of the license line of business.

19


    A $1.9 million impairment charge related to assets and liabilities associated with certain products of which we are divesting ourselves. These assets have historically been considered to be part of our license line of business. As part of the cost reductions, we decided that we would no longer devote resources to the development or support of these products. The fair value of the related assets was determined from letters of intent to purchase the intellectual property.

    Summary of Restructuring Accruals

        In the fourth quarter of fiscal 2002, we initiated a plan to reduce operating expenses and to restructure operations around our two primary product lines, engineering software and manufacturing/supply chain software. We reduced worldwide headcount by approximately 10% or 200 employees, closed-down and consolidated facilities, and disposed of certain assets, resulting in an aggregate restructuring charge of $14.4 million. As of December 31, 2002, there was $7.6 million remaining in accrued expenses relating to the remaining severance obligations and lease payments. During the three months ended December 31, 2002, the following activity was recorded:

 
  Closedown/
Consolidation
of Facilities

  Employee
Severance,
Benefits, and
Related Costs

  Total
 
Accrued expenses, September 30, 2002   $ 4,838   $ 4,088   $ 8,926  
Payments     (70 )   (1,290 )   (1,360 )
   
 
 
 
Accrued expenses, December 31, 2002   $ 4,768   $ 2,798   $ 7,566  
   
 
 
 

We expect that the remaining obligations will be paid-out by December 2010.

        During the first quarter of fiscal 2002, in light of further economic uncertainties, our management made a decision to adjust our business plan by further reducing spending. This change in business plan consisted of a reduction in worldwide headcount of approximately 5% of the workforce and a reduction of certain future discretionary expenses. As a result of these measures, we recorded a restructuring charge of $2.6 million, primarily for severance, for the quarter ended September 30, 2001. As of December 31, 2002, all obligations had been paid-out. During the three months ended December 31, 2002, the following activity was recorded:

 
  Employee
Severance,
Benefits, and
Related Costs

        In the third quarter of fiscal 2001, the revenues realized were below expectations as customers delayed spending in the widespread slowdown in information technology spending and the deferral of late-quarter purchasing decisions. At that time, we also reduced our revenue expectations for the fourth quarter of fiscal year 2001 and for the fiscal year 2002. Based on the reduced revenue expectations, management evaluated the business plan and made significant changes, resulting in a restructuring plan for our operations. This restructuring plan included a reduction in headcount, a substantial decrease in discretionary spending and a sharpening of our e-business focus to emphasize our marketplace solutions. The restructuring plan resulted in a pretax charge totaling $7.0 million. As of December 31,

2002, there was $0.9 million remaining in accrued expenses relating to the restructuring. During the three months ended December 31, 2002, the following activity was recorded:

 
  Closedown/
Consolidation
of Facilities

  Total
 
Accrued expenses, September 30, 2002   $ 1,105   $ 1,105  
Payments     (190 )   (190 )
   
 
 
Accrued expenses, December 31, 2002   $ 915   $ 915  
   
 
 

We expect that the remaining obligations will be paid-out by March 2008.

        In the fourth quarter of fiscal 1999, we undertook certain actions to restructure our business. The restructuring resulted from a lower than expected level of license revenues which adversely affected fiscal year 1999 operating results. The license revenue shortfall resulted primarily from delayed decision making driven by economic difficulties among customers in certain of our core vertical markets. The restructuring plan resulted in a pre-tax restructuring charge totaling $17.9 million. As of December 31, 2002, there was $0.6 million remaining in the accrued expenses relating to the restructuring. During the three months ended December 31, 2002, the following activity was recorded:

 
  Closedown/
Consolidation
of Facilities

Accrued expenses, September 30, 2002   $ 274
Net sub-lease receipts (lease payments)     324
   
Accrued expenses, December 31, 2002   $ 598
   

We expect that the remaining obligations will be paid-out by December 2004.

Critical Accounting Estimates and Judgments

        Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of our financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures. We base our estimates on historical experience and 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 that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. The significant accounting policies that we believe are the most critical to aid in fully understanding and evaluating our reported financial results include the following:

    Revenue recognition for both software licenses and fixed-fee consulting services,

    Impairment of long-lived assets, goodwill and intangible assets,

    Accounting for income taxes, and

    Allowance for doubtful accounts.

Revenue Recognition—Software Licenses

        We recognize software license revenue in accordance with American Institute of Certified Public Accountants (AICPA) Statement of Position, or SOP, No. 97-2, "Software Revenue Recognition", as amended by SOP No. 98-4 and SOP No. 98-9, as well as the various interpretations and clarifications

21



of those statements. These statements require that four basic criteria must be satisfied before software license revenue can be recognized:

    persuasive evidence of an arrangement between ourselves and a third party exists;

    delivery of our product has occurred;

    the sales price for the product is fixed or determinable; and

    collection of the sales price is probable.

Our management uses its judgment concerning the satisfaction of these criteria, particularly the criteria relating to the determination of whether the fee is fixed and determinable and the criteria relating to the collectibility of the receivables relating to such sales. Should changes and conditions cause management to determine that these criteria are not met for certain future transactions, all or substantially all of the software license revenue recognized for such transactions could be deferred.

Revenue Recognition—Consulting Services

        We recognize revenue associated with fixed-fee service contracts in accordance with AICPA SOP No. 81-1, "Accounting for Performance of Construction-Type and Certain Production-Type Contracts", using the percentage-of-completion method, measured by the percentage of costs (primarily labor) incurred to date as compared to the estimated total costs (primarily labor) for each contract. When a loss is anticipated on a contract, the full amount of the anticipated loss is provided currently. Our management uses its judgment concerning the estimation of the total costs to complete the contract, considering a number of factors, including the experience of the personnel that are performing the services and the overall complexity of the project. Should changes and conditions cause actual results to differ significantly from management's estimates, revenue recognized in future periods could be adversely affected.

Impairment of Long-lived Assets, Goodwill and Intangible Assets

        In accordance with SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets", we review the carrying value of long-lived assets periodically, based upon the expected future operating cash flows of our business. These future cash flow estimates are based on historical results, adjusted to reflect our best estimate of future markets and operating conditions, and are continuously reviewed based on actual operating trends. Actual results may differ materially from these estimates.

        In accordance with SFAS No. 142, "Goodwill and Other Intangible Assets", we conduct at least an annual assessment of the carrying value of our goodwill assets. We obtain a third-party valuation of the reporting units associated with the goodwill assets, which is based on either estimates of future income from the reporting units or estimates of the market value of the units, based on comparable recent transactions. These estimates of future income are based upon historical results, adjusted to reflect our best estimate of future markets and operating conditions, and are continuously reviewed based on actual operating trends. Actual results may differ materially from these estimates. In addition, the relevancy of recent transactions used to establish market value for our reporting units is based on management's judgment.

        During the three months ended December 31, 2002, we recorded charges related to the impairment of certain long-lived assets and intangible assets and a portion of our goodwill. The timing and size of future impairment charges involves the application of management's judgment and estimates and could result in the write-off of all or substantially all of our long-lived assets, intangible assets and goodwill.

22



Accounting for Income Taxes

        As part of the process of preparing our consolidated financial statements we are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves us estimating our actual current tax liabilities together with assessing temporary differences resulting from differing treatment of items, such as deferred revenue, for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within our consolidated balance sheet. Tax assets also result from net operating losses, research and development tax credits and foreign tax credits. We must then assess the likelihood that our deferred tax assets will be recovered from future taxable income and to the extent we believe that recovery is not likely, we must establish a valuation allowance. To the extent we establish a valuation allowance or increase this allowance in a period, the impact will be included in the tax provision in the statement of operations.

        Significant management judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities and any valuation allowance recorded against our deferred tax assets. The valuation allowance is based on our estimates of taxable income by jurisdiction in which we operate and the period over which our deferred tax assets will be recoverable. In the event that actual results differ from these estimates or we adjust these estimates in future periods we may need to establish an additional valuation allowance which could result in a tax provision equal to the carrying value of our deferred tax assets.

    Allowance for Doubtful Accounts

        We make judgments as to our ability to collect outstanding receivables and provide allowances for the portion of receivables when collection becomes doubtful. Provisions are made based upon a specific review of all significant outstanding invoices. For those invoices not specifically reviewed, provisions are provided at differing rates, based upon the age of the receivable. In determining these percentages, we analyze our historical collection experience and current economic trends. If the historical data we use to calculate the allowance provided for doubtful accounts do not reflect the future ability to collect outstanding receivables, additional provisions for doubtful accounts may be required for all or substantially all of certain receivable balances.

Comparison of the Three and Six Months Ended December 31, 2002 and 2001

Total Revenues

        Revenues are derived from software licenses and maintenance and other services. Total revenues for the three months ended December 31, 2002 decreased 4.6% to $83.0 million from $87.0 million in the three months ended December 31, 2001. Total revenues for the six months ended December 31, 2002 increased 4.6% to $160.2 million from $153.2 million in the six months ended December 31, 2001.

        Total revenues from customers outside the United States were $41.7 million and $82.3 million, or 50.3% and 51.4% of total revenues, for the three and six months ended December 31, 2002 respectively, as compared to $31.5 million and $65.3 million, or 36.2% and 42.6% of total revenues, for the three and six months ended December 31, 2001. The geographical mix of license revenues can vary from quarter to quarter; however, for fiscal 2003, the overall geographical mix of revenues from customers outside the United States is expected to be relatively consistent with the prior fiscal year.

24



Software License Revenues

        Software license revenues represented 44.3% of total revenues for the three months ended December 31, 2002, as compared to 45.9% in the three months ended December 31, 2001. Revenues from software licenses for the three months ended December 31, 2002 decreased 7.9% to $36.8 million from $39.9 million in the three months ended December 31, 2001. This decrease primarily was due to the overall decline in demand for our manufacturing/supply chain products, in addition to the inclusion in the three months ended December 31, 2001 of software license revenue from a significant purchase by The Dow Chemical Company, offset by the inclusion of software license revenue associated with Hyprotech, which we acquired in May 2002.

        Software license revenues represented 41.5% of total revenues for the six months ended December 31, 2002, as compared to 38.6% in the six months ended December 31, 2001. Revenues from software licenses for the six months ended December 31, 2002 increased 12.3% to $66.4 million from $59.2 million in the six months ended December 31, 2001. This increase for the comparable six month periods was due a 54.2% increase in license revenue in the three months ended September 30, 2002, as compared to the three months ended September 30, 2001. This increase was due to the inclusion in the three months ended September 30, 2002 of software license revenue associated with Hyprotech, and the negative impact of the September 11, 2001 attacks on the closure rate of license agreements in the final weeks of the three months ended September 30, 2001.

Service and Other Revenues

        Revenues from service and other consist of consulting services, post contract support on software licenses, training and sales of documentation. Revenues from service and other for the three months ended December 31, 2002 decreased 1.8% to $46.2 million, from $47.1 million in the three months ended December 31, 2001. Revenues from service and other for the six months ended December 31, 2002 decreased 0.2% to $93.8 million, from $94.0 million in the six months ended December 31, 2001.

        These decreases reflect a decline in revenues from our consulting business, partially offset by the inclusion in the three and six months ended December 31, 2002 of service and other revenue associated with Hyprotech, which we acquired in May 2002. The decline in consulting revenue primarily was related to the decline in demand for our manufacturing/supply chain software products, along with which we typically sell consulting projects. The decline is also due to reductions in headcount, offset by the inclusion of service and other revenue from Hyprotech.

Cost of Software Licenses

        Cost of software licenses consists of royalties, amortization of previously capitalized software costs, costs related to the delivery of software, including disk duplication and third party software costs, printing of manuals and packaging. Cost of software licenses for the three months ended December 31, 2002 increased 15.0% to $3.5 million, from $3.1 million in the three months ended December 31, 2001. Cost of software licenses for the six months ended December 31, 2002 increased 24.5% to $6.8 million, from $5.5 million in the six months ended December 31, 2001. Cost of software licenses as a percentage of revenues from software licenses was 9.5% and 10.3% for the three and six months ended December 31, 2002, respectively, as compared to 7.6% and 9.3% for the three and six months ended December 31, 2001, respectively.

        The increases in software license costs, in both absolute dollars and as a percentage of revenues from software licenses, were due to the July 2002 inception of the Accenture royalty agreement and a general increase in the amortization of capitalized software costs.

25



Cost of Service and Other

        Cost of service and other consists of the cost of execution of application consulting services, technical support expenses and the cost of training services. Cost of service and other for the three months ended December 31, 2002 decreased 11.4% to $26.8 million from $30.3 million in the three months ended December 31, 2001. Cost of service and other for the six months ended December 31, 2002 decreased 9.2% to $54.8 million from $60.4 million in the six months ended December 31, 2001. Cost of service and other as a percentage of service and other revenues was 58.1% and 58.5% in the three and six months ended December 31, 2002, respectively, as compared to 64.3% and 64.2% in the three and six months ended December 31, 2001.

        This decrease in absolute dollars was due to the reductions in headcount that occurred in May 2002 and October 2002. The decrease as a percentage of service and other revenues was due to the headcount reductions, as well as the increase of revenues from software maintenance as a percentage of service and other revenue, a service that provides higher margins than consulting services.

Selling and Marketing Expenses

        Selling and marketing expenses for the three months ended December 31, 2002 decreased 5.0% to $27.0 million from $28.5 million in the three months ended December 31, 2001. Selling and marketing expenses for the six months ended December 31, 2002 increased 2.0% to $56.2 million from $55.1 million in the six months ended December 31, 2001. As a percentage of total revenues, selling and marketing expenses were 32.6% and 35.1% for the three and six months ended December 31, 2002, respectively, as compared to 32.7% and 36.0% for the three and six months ended December 31, 2001, respectively.

        The decrease in absolute dollars for the comparable three-month periods was attributable to the headcount reductions that took place in October 2002, offset by the amortization of costs associated with our October 2002 AspenWorld conference and by the inclusion of Hyprotech costs in the three months ended December 31, 2002. The increase in absolute dollars for the comparable six-month periods was primarily due to an increase in sales commissions related to higher license revenues in the three months ended September 30, 2002 as compared to the three months ended September 30, 2001 in addition to abovementioned AspenWorld and Hyprotech costs in the six months ended December 31, 2002.

Research and Development Expenses

        Research and development expenses consist primarily of personnel and outside consultancy costs required to conduct our product development efforts. Capitalized research and development costs are amortized over the estimated remaining economic life of the relevant product, not to exceed three years. Research and development expenses during the three months ended December 31, 2002 decreased 10.3% to $16.0 million from $17.8 million in the three months ended December 31, 2001. Research and development expenses during the six months ended December 31, 2002 decreased 5.8% to $33.7 million from $35.8 million in the six months ended December 31, 2001. As a percentage of revenues, research and development costs were 19.3% and 21.1% for the three and six months ended December 31, 2002, respectively, as compared to 20.5% and 23.4% for the three and six months ended December 31, 2001, respectively.

        The decrease in absolute dollars was attributable to the effect of reductions in headcount from the September 2001, May 2002 and October 2002 restructuring plans, partially offset by the inclusion in the three and six months ended December 31, 2002 of costs associated with Hyprotech. We capitalized 13.6% and 16.8% of our total research and development costs during the three and six months ended December 31, 2002, respectively. Of these amounts, 8.0% and 2.5%, respectively, related to

26



development costs incurred by Accenture and the amortization of the purchased intellectual property. The remaining 11.1% and 11.2%, respectively, related to our internal development costs, as compared to 8.0% and 7.9% in the three and six months ended December 31, 2001. This increase in capitalized costs was due to two large development projects that were nearing completion during the six months ended December 31, 2002, for which nearly all costs incurred were eligible for capitalization.

General and Administrative Expenses

        General and administrative expenses consist primarily of salaries of administrative, executive, financial and legal personnel, outside professional fees, and amortization of intangible assets. General and administrative expenses for the three months ended December 31, 2002 increased 18.7% to $8.9 million from $7.5 million for the three months ended December 31, 2001. General and administrative expenses for the six months ended December 31, 2002 increased 25.4% to $18.7 million from $14.9 million for the six months ended December 31, 2001.

        These increases were attributable primarily to a higher level of amortization relating to other intangible assets arising from our acquisition of Hyprotech in May 2002 and the inclusion of Hyprotech costs in fiscal 2003, both offset by the effect of reductions in headcount from the September 2001, May 2002 and October 2002 restructuring plans.

Interest Income

        Interest income is generated from the investment of excess cash in short-term and long-term investments and from the license of software pursuant to installment contracts. Under these installment contracts, we offer customers the option to make annual payments for its term licenses instead of a single license fee payment at the beginning of the license term. Historically, a substantial majority of the engineering software customers have elected to license our products through installment contracts, while significantly all of our manufacturing/supply chain customers have selected perpetual licenses for which payment is generally made up-front. Included in the annual payments of the installment contracts is an implicit interest charge based upon the interest rate established by us at the time of the license. If the mix of sales moves away from installment contracts, the interest income from these contracts in future periods will be reduced. We sell a portion of the installment contracts to unrelated financial institutions. The interest earned by us on the installment contract portfolio in any period is the result of the implicit interest established by us on installment contracts and the size of the contract portfolio. Interest income was $2.5 million and $4.6 million for the three and six months ended December 31, 2002, respectively, as compared to $1.5 and $3.6 for the three and six months ended December 31, 2001. These increases are due to the increase of installment contracts associated with Hyprotech, which we acquired in May 2002.

Interest Expense

        Interest expense is generated from interest charged on our 51/4% convertible debentures, notes payable and capital lease obligations. Interest expense was $2.3 million and $3.8 million for the three and six months ended December 31, 2002, respectively, as compared to $1.3 million and $2.6 million for the three and six months ended December 31, 2001. This increase was due to interest on the amounts owed to Accenture and a general increase in the amount of capital leases.

Tax Rate

        We did not record an income tax provision or benefit for the three or six months ended December 31, 2002, as we provided a full valuation against the tax loss carryforwards that were generated during the period. The effective tax rate for the three and six months ended December 31, 2001 was approximately 30.0% of pretax loss.

27



Liquidity and Capital Resources

        During the six months ended December 31, 2002, our cash and cash equivalents balance increased by $17.0 million. Net cash provided by operations was $11.1 million due primarily to the decrease in accounts receivable and unbilled services, offset by the net loss. Net cash provided by investing activities was $9.6 million due to the sale of investment securities of $15.5 million, partially offset by capital purchases of $2.9 million and an increase in computer software development of $4.1 million. Net cash used in financing activities was $4.0 million, consisting primarily of $3.2 million in payments on long-term debt and capital leases and $3.1 million in payments to Accenture, offset by $2.2 million in proceeds from the issuance of common stock under our employee stock purchase plan. During the six months ended December 31, 2002, we acquired $1.1 million of equipment and software by entering into capital lease arrangements.

        Historically, we have had arrangements to sell long-term contracts to two financial institutions, General Electric Capital Corporation and Fleet Business Credit Corporation. These contracts represent amounts due over the life of existing term licenses. During the six months ended December 31, 2002, installment contracts decreased by $3.0 million to $105.7 million, net of $32.6 million of installment contracts sold to General Electric Credit Corporation and Fleet Business Credit Corporation. Our arrangements with these two financial institutions provide for the sale of installment contracts up to a maximum of $160.0 million, subject to approval by the institutions, having certain recourse obligations. At December 31, 2002, the balance of the uncollected principal portion of the contracts sold to these two financial institutions was $138.5 million, for which we had a partial recourse obligation that was within the range of $6.8 million to $9.2 million. We expect that there will be continued availability under the arrangements, as the collection of the sold receivables will reduce this outstanding balance, and the maximum limits under the arrangements can be increased.

        In January 2003, we executed a Loan Arrangement with Silicon Valley Bank. This arrangement provides a line of credit of up to the lesser of (i) $15.0 million or (ii) 70% of eligible domestic receivables, and a line of credit of up to the lesser of (i) $10.0 million or (ii) 80% of eligible foreign receivables. The lines of credit bear interest at the bank's prime rate (4.25% at December 31, 2002) plus 1/2%, which may be reduced to the bank's prime rate upon the achievement of two consecutive quarters of net income. We are required to maintain a $4.0 million compensating cash balance with the bank, or be subject to an unused line fee and collateral handling fees. The lines of credit will initially be collateralized by nearly all of our assets, and upon achieving certain net income targets, the collateral will be reduced to a lien on our accounts receivable. We are required to meet certain financial covenants, including minimum tangible net worth, minimum cash balances and an adjusted quick ratio. The Loan Arrangement expires in January 2005.

        In February and March 2002, we issued and sold 40,000 shares of Series B-I convertible preferred stock and 20,000 shares of Series B-II convertible preferred stock, together with warrants to purchase 791,044 shares of common stock, for an aggregate purchase price of $60.0 million. The Series B preferred stock accrues dividends at an annual rate of 4% that is payable quarterly, commencing in June 30, 2002, in either cash or common stock, at our option (subject to our satisfaction of specified conditions set forth in our charter). On January 2, 2003, we issued 196,971 shares of common stock in satisfaction of this obligation for the three months ended December 31, 2002.

        As of December 31, 2002, we had cash and cash-equivalents totaling $50.6 million, as well as short-term investments totaling $3.1 million. Our commitments as of December 31, 2002, consisted primarily of amounts owed to Accenture, capital lease obligations and leases on our headquarters and other facilities. Other than these, there were no other material commitments for capital or other

28



expenditures. Our obligations related to these items as of December 31, 2002 are as follows (in thousands):

 
  2003
  2004
  2005
  2006
  2007
  Thereafter
Non-cancelable operating leases   $ 8,704   $ 12,932   $ 11,373   $ 11,480   $ 11,405   $ 45,888

        We believe our current cash balances, availability of sales of our installment contracts, availability under the Silicon Valley Bank line of credit and cash flows from our operations will be sufficient to meet our working capital and capital expenditure requirements for at least the next 12 months. However, we may need to obtain additional financing thereafter or earlier, if our current plans and projections prove to be inaccurate or our expected cash flows prove to be insufficient to fund our operations because of lower-than-expected revenues, unanticipated expenses or other unforeseen difficulties. In addition, we may seek to take advantage of favorable market conditions by raising additional funds from time to time through public or private security offerings, debt financings, strategic alliances or other financing sources. Our ability to obtain additional financing will depend on a number of factors, including market conditions, our operating performance and investor interest. These factors may make the timing, amount, terms and conditions of any financing unattractive. They may also result in our incurring additional indebtedness or accepting stockholder dilution. If adequate funds are not available or are not available on acceptable terms, we may have to forego strategic acquisitions or investments, reduce or defer our development activities, or delay our introduction of new products and services. Any of these actions may seriously harm our business and operating results.

Factors that may Affect Future Results and the Trading Price of Our Common Stock

        INVESTING IN OUR COMMON STOCK INVOLVES A HIGH DEGREE OF RISK. YOU SHOULD CAREFULLY CONSIDER THE RISKS AND UNCERTAINTIES DESCRIBED BELOW BEFORE PURCHASING OUR COMMON STOCK. THE RISKS AND UNCERTAINTIES DESCRIBED BELOW ARE NOT THE ONLY ONES FACING OUR COMPANY. ADDITIONAL RISKS AND UNCERTAINTIES MAY ALSO IMPAIR OUR BUSINESS OPERATIONS. IF ANY OF THE FOLLOWING RISKS ACTUALLY OCCUR, OUR BUSINESS, FINANCIAL CONDITION OR RESULTS OF OPERATIONS WOULD LIKELY SUFFER. IN THAT CASE, THE TRADING PRICE OF OUR COMMON STOCK COULD FALL, AND YOU MAY LOSE ALL OR PART OF THE MONEY YOU PAID TO BUY OUR COMMON STOCK.

        Our lengthy sales cycle makes it difficult to predict quarterly revenue levels and operating results.

        Because license fees for our software products are substantial and the decision to purchase our products typically involves members of our customers' senior management, the sales process for our solutions is lengthy and can exceed one year. Accordingly, the timing of our license revenues is difficult to predict, and the delay of an order could cause our quarterly revenues to fall substantially below expectations. Moreover, to the extent that we succeed in shifting customer purchases away from individual software products and toward more costly integrated suites of software and services, our sales cycle may lengthen, which could increase the likelihood of delays and cause the effect of a delay to become more pronounced. We have limited experience in forecasting the timing of sales of our integrated suites of software and services. Delays in sales could cause significant shortfalls in our revenues and operating results for any particular period.

        Fluctuations in our quarterly revenues, operating results and cash flow may cause the market price of our common stock to fall.

        Our revenues, operating results and cash flow have fluctuated in the past and may fluctuate significantly in the future as a result of a variety of factors, many of which are outside of our control, including:

    our customers' purchasing patterns;

    the length of our sales cycle;

    changes in the mix of our license revenues and service revenues;

30


    the timing of introductions of new solutions and enhancements by us and our competitors;

    seasonal weakness in the first quarter of each fiscal year, primarily caused by a slowdown in business in some of our international markets;

    the timing of our investments in new product development;

    changes in our operating expenses; and

    fluctuating economic conditions, particularly as they affect companies in the chemicals, petrochemicals and petroleum industries.

        We ship software products within a short period after receipt of an order and typically do not have a material backlog of unfilled orders for software products. Consequently, revenues from software licenses in any quarter are substantially dependent on orders booked and shipped in that quarter. Historically, a majority of each quarter's revenues from software licenses has come from license agreements that have been entered into in the final weeks of the quarter. Therefore, even a short delay in the consummation of an agreement may cause our revenues to fall below public expectations for that quarter.

        Since our expense levels are based in part on anticipated revenues, we may be unable to adjust spending quickly enough to compensate for any revenue shortfall and any revenue shortfall would likely have a disproportionately adverse effect on our operating results. We expect that these factors will continue to affect our operating results for the foreseeable future. Because of the foregoing factors, we believe that period-to-period comparisons of our operating results are not necessarily meaningful and should not be relied upon as indications of future performance.

        If, due to one or more of the foregoing factors or an unanticipated cause, our operating results fail to meet the expectations of public market analysts and investors in a future quarter, the market price of our common stock would likely decline. Since April 5, 2002, the date on which we preliminarily announced our estimated results for the three months ended March 31, 2002, through the close of business on February 10, 2003, the price per share of our common stock, as reported by the Nasdaq National Market, decreased from $17.37 to $2.95.

        The Federal Trade Commission may challenge our acquisition of Hyprotech.

        By letter of June 7, 2002, the Federal Trade Commission, or FTC, informed us that it was conducting an investigation into the competitive effects of our recent acquisition of Hyprotech. The FTC may determine to challenge the acquisition through an administrative civil complaint seeking to declare the acquisition in violation of Section 7 of the Clayton Act or Section 5 of the FTC Act. If the FTC were to prevail in that challenge, it could seek to impose a wide variety of remedies, some of which may have a material adverse effect on our ability to continue to operate under our current business plans. These potential remedies include divestiture of Hyprotech, as well as mandatory licensing of Hyprotech software products and our other engineering software products to one or more of our competitors.

        We can provide no assurance as to the outcome of the FTC's investigation. Any conclusion of this investigation in a manner adverse to us would have a material adverse effect on our business and results of operations. In addition, the cost to us of continuing to cooperate in the investigation or of defending any litigation or other proceeding that may result from the investigation, even if resolved in our favor, could be substantial. The continuance of the investigation or any commencement of litigation or any other proceeding would continue to divert the attention of our management. Uncertainties resulting from the continuation of this investigation or the initiation of litigation or other proceedings could harm our ability to compete in the marketplace.

31



        Because we derive a majority of our total revenues from customers in the cyclical chemicals, petrochemicals and petroleum industries, our operating results may suffer if these industries experience an economic downturn.

        We derive a majority of our total revenues from companies in the chemicals, petrochemicals and petroleum industries. Accordingly, our future success depends upon the continued demand for manufacturing optimization software and services by companies in these process manufacturing industries. The chemicals, petrochemicals and petroleum industries are highly cyclical and highly reactive to the price of oil, as well as general economic conditions. In the past, worldwide economic downturns and pricing pressures experienced by chemical, petrochemical and petroleum companies have led to consolidations and reorganizations. These downturns, pricing pressures and restructurings have caused delays and reductions in capital and operating expenditures by many of these companies. These delays and reductions have reduced demand for products and services like ours. A recurrence of these industry patterns, as well as general domestic and foreign economic conditions and other factors that reduce spending by companies in these industries, could harm our operating results in the future.

        If economic conditions and the markets for our products do not improve, sales of our product lines, particularly our manufacturing and supply chain product suites, will be adversely affected.

        Adverse changes in the economy and continuing global uncertainty have caused delays and reductions in information technology spending by our customers and a consequent deterioration of the markets for our products and services, particularly our manufacturing and supply chain product suites. If these adverse economic conditions continue or worsen, we will experience further reductions, delays, and postponements of customer purchases that will negatively impact our revenue and operating results. If economic and political conditions and the market for our products do not improve and our revenues decline, our business could be harmed, and we may not be able to further reduce our costs to align them with these decreased revenues.

        We may require additional capital.

        We may need to raise additional capital in order to fund the continued development and marketing of our solutions. We expect our current cash balances, cash-equivalents, short-term investments, availability of sales of our installment contracts, availability under the Silicon Valley Bank lines of credit and cash flows from operations will be sufficient to meet our working capital and capital expenditure requirements for at least the next twelve months. However, we may need to obtain additional financing thereafter or earlier, if our current plans and projections prove to be inaccurate or our expected cash flows prove to be insufficient to fund our operations because of lower-than-expected revenues, unanticipated expenses or other unforeseen difficulties. An important part of our cash management program is the sale of receivables. Historically, we have had arrangements to sell long-term contracts to two financial institutions, General Electric Capital Corporation and Fleet Business Credit Corporation. These contracts represent amounts due over the life of existing term licenses. During the six months ended December 31, 2002, installment contracts decreased by $3.0 million to $105.7 million, net of $32.6 million of installment contracts sold to General Electric Credit Corporation and Fleet Business Credit Corporation. Our ability to continue these arrangements or replace them with similar arrangements is important to maintaining adequate funding. In addition, in August 2002, we amended several of the terms of our strategic alliance with Accenture, which will require us to make monthly cash payments totaling $11.1 million, $8.0 million of which is outstanding as of December 31, 2002 and payable in installments through July 2003, instead of the originally agreed-to stock payment in August 2002. Our ability to obtain additional financing will depend on a number of factors, including market conditions, our operating performance and investor interest. These factors may make the timing, amount, terms and conditions of any financing unattractive. They may also result in our incurring additional indebtedness or accepting stockholder dilution. In 2002, we

32



issued convertible preferred stock and common stock warrants that contain anti-dilution provisions, rights of first refusal and other terms that may limit or impair our ability to raise additional funds through future financings. If adequate funds are not available or are not available on acceptable terms, we may have to forego strategic acquisitions or investments, reduce or defer our development activities, or delay our introduction of new products and services. Any of these actions may seriously harm our business and operating results.

        If we do not compete successfully, we may lose market share.

        Our markets are highly competitive. Our engineering software competes with products of businesses such as Simulation Sciences, a division of Invensys, Shell Global Solutions, ABB, MDC Technology, Cadcentre, WinSim, Inc. (formerly ChemShare) and Process Systems Enterprise Ltd. As we expand our engineering solutions into the collaborative Process asset Lifecycle Management (PLM) market we may see competition from companies that we have not typically competed against in the past, such as Agile, PTC, and EDS. Our manufacturing/supply chain software competes with products of companies such as Honeywell's Hi-Spec division, Invensys, ABB, Rockwell, i2 Technologies, Manugistics and certain components of SAP's supply chain offering. We also face competition in all three areas from large companies in the process industries that have developed their own proprietary software solutions.

        Some of our current competitors have significantly greater financial, marketing and other resources than we have. In addition, many of our current competitors have established, and may in the future continue to establish, cooperative relationships with third parties to improve their product offerings and to increase the availability of their products to the marketplace. The entry of new competitors or alliances into our market could reduce our market share, require us to lower our prices, or both. Many of these factors are outside our control, and we may not be able to maintain or enhance our competitive position against current and future competitors.

        If we fail to integrate the operations of the companies we acquire, we may not realize the anticipated benefits and our operating costs could increase.

        We intend to continue to pursue strategic acquisitions that will provide us with complementary products, services and technologies and with additional personnel. The identification and pursuit of these acquisition opportunities and the integration of acquired personnel, products, technologies and businesses require a significant amount of management time and skill. There can be no assurance that we will identify suitable acquisition candidates, consummate any acquisition on acceptable terms or successfully integrate any acquired business into our operations. Additionally, in light of the consolidation trend in our industry, we expect to face competition for acquisition opportunities, which may substantially increase the cost of any potential acquisition.

        We have experienced in the past, and may experience again in the future, problems integrating the operations of a newly acquired company with our own operations. Acquisitions also expose us to potential risks, including diversion of management's attention, failure to retain key acquired personnel, assumption of legal or other liabilities and contingencies, and the amortization of acquired intangible assets. Moreover, customer dissatisfaction with, or problems caused by, the performance of any acquired products or technologies could hurt our reputation.

        In particular, on May 31, 2002, we purchased the capital stock of Hyprotech Ltd. and related subsidiaries of AEA for £66.2 million (or $96.6 million, based on the exchange rate as of May 9, 2002, the date of the agreement) in cash. The Hyprotech business operates globally and is the second largest acquisition we have made. The integration of the personnel, products and technologies of Hyprotech will require significant management time and skill, and our inability to complete the acquisition effectively and efficiently could cause our operating results to suffer.

33



        We funded the Hyprotech acquisition substantially from the proceeds of convertible preferred stock and common stock financings effected in 2002. We may issue additional equity securities or incur long-term indebtedness to finance future acquisitions. The issuance of equity securities could result in dilution to existing stockholders, while the use of cash reserves or significant debt financing could reduce our liquidity and weaken our financial condition.

        Our operating results may be harmed if our restructuring plans and cost reduction measures do not achieve the anticipated results or cause undesirable consequences.

        Since the fourth quarter of fiscal 1999, we have implemented restructuring plans and cost reduction measures, which have included, among other things, significant workforce reductions. Because of the nature and extent of the restructuring actions we have taken to date, we may be unable to initiate additional, significant restructuring measures in future periods. If we fail to achieve the desired results of our restructuring plans and our cost reduction measures, we may suffer material harm to our business.

        Our recent cost reduction initiative may yield unintended consequences, such as attrition beyond our planned reduction in workforce and reduced employee morale. In addition, the recent trading levels of our stock have decreased the value of our stock options granted to employees under our stock option plans. As a result of these factors, our employees may seek alternate employment. Attrition beyond our planned reduction in workforce could have a material adverse effect on our financial performance.

        If we do not continue to make the technological advances required by the marketplace, our business could be seriously harmed.

        Enterprises are requiring their application software vendors to provide greater levels of functionality and broader product offerings. Moreover, competitors continue to make rapid technological advances in computer hardware and software technology and frequently introduce new products, services and enhancements. We must continue to enhance our current product line and develop and introduce new products and services that keep pace with the technological developments of our competitors. Our business and operating results could suffer if we cannot successfully respond to the technological advances of others or if our new products or product enhancements and services do not achieve market acceptance.

        We must also satisfy increasingly sophisticated customer requirements. Under our business plan, we are investing significantly in the development of new business process products that are intended to anticipate and meet the emerging needs of our target market. We are focusing significantly on development of these products, which means we will not invest as substantially in the continued enhancement of our current products. We cannot assure you that our new product development will result in products that will meet market needs and achieve market acceptance.

        Moreover, a portion of our product development for enterprise solutions in the foreseeable future is expected to be conducted through co-development arrangements with Accenture LLP that we entered into in February 2002. Our business and operating results will be harmed if this co-development arrangement does not result in our being able to deliver timely products sought by companies in the process industries.

        If we are unable to successfully market our products to senior executives of potential customers, our revenue growth may be limited.

        With the development of our integrated manufacturing/supply chain solutions and the new solutions we are developing with Accenture, we are increasingly focused on selling the strategic value of our technology to the highest executive levels of customer organizations, typically the chief executive

34



officer, chief financial officer or chief information officer. We have limited experience in selling and marketing at these levels. If we are not successful at selling and marketing to senior executives, our revenue growth and operating results could suffer.

        If we are unable to develop relationships with strategic partners, our revenue growth may be harmed.

        An element of our growth strategy is to strategically partner with a few select third-party implementation partners who market and integrate our products. The most significant of these partnerships is our joint marketing and development alliance with Accenture. If we do not adequately train a sufficient number of systems integrator partners, or if potential partners focus their efforts on integrating or co-selling competing products to the process industries, our future revenue growth could be limited and our operating results could be harmed. If our partners fail to implement our solutions for our customers properly, the reputations of our solutions and our company could be harmed and we might be subject to claims by our customers. We intend to continue to establish business relationships with technology companies to accelerate the development and marketing of our solutions. To the extent that we are unsuccessful in maintaining our existing relationships and developing new relationships, our revenue growth may be harmed.

        We may suffer losses on fixed-price engagements.

        We derive a substantial portion of our total revenues from service engagements and a significant percentage of these engagements have been undertaken on a fixed-price basis. We bear the risk of cost overruns and inflation in connection with fixed-price engagements, and as a result, any of these engagements may be unprofitable. In the past, we have had cost overruns on fixed-price service engagements. In addition, to the extent that we are successful in shifting customer purchases to our integrated suites of software and services and we price those engagements on a fixed-price basis, the size of our fixed-price engagements may increase, which could cause the impact of an unprofitable fixed-price engagement to have a more pronounced impact on our operating results.

        Our business may suffer if we fail to address the challenges associated with international operations.

        We derived approximately 50% of our total revenues from customers outside the United States in each of the past three fiscal years. We anticipate that revenues from customers outside the United States will continue to account for a significant portion of our total revenues for the foreseeable future. Our operations outside the United States are subject to additional risks, including:

    unexpected changes in regulatory requirements, exchange rates, tariffs and other barriers;

    political and economic instability;

    difficulties in managing distributors and representatives;

    difficulties in staffing and managing foreign subsidiary operations;

    difficulties and delays in translating products and product documentation into foreign languages;

    difficulties and delays in negotiating software licenses compliant with U.S. accounting revenue recognition requirements; and

    potentially adverse tax consequences.

        The impact of future exchange rate fluctuations on our operating results cannot be accurately predicted. In recent years, we have increased the extent to which we denominate arrangements with international customers in the currencies of the countries in which the software or services are provided. From time to time we have engaged in, and may continue to engage in, hedges of a significant portion of installment contracts denominated in foreign currencies. Any hedging policies

35



implemented by us may not be successful, and the cost of these hedging techniques may have a significant negative impact on our operating results.

        We may not be able to protect our intellectual property rights, which could make us less competitive and cause us to lose market share.

        We regard our software as proprietary and rely on a combination of copyright, patent, trademark and trade secret laws, license and confidentiality agreements, and software security measures to protect our proprietary rights. We have registered or have applied to register several of our significant trademarks in the United States and in certain other countries. We generally enter into non-disclosure agreements with our employees and customers, and historically have restricted access to our software products' source codes, which we regard as proprietary information. In a few cases, we have provided copies of the source code for some of our products to customers solely for the purpose of special product customization and have deposited copies of the source code for some of our products in third-party escrow accounts as security for ongoing service and license obligations. In these cases, we rely on non-disclosure and other contractual provisions to protect our proprietary rights.

        The steps we have taken to protect our proprietary rights may not be adequate to deter misappropriation of our technology or independent development by others of technologies that are substantially equivalent or superior to our technology. Any misappropriation of our technology or development of competitive technologies could harm our business, and could force us to incur substantial costs in protecting and enforcing our intellectual property rights. The laws of some countries in which our products are licensed do not protect our products and intellectual property rights to the same extent as the laws of the United States.

        We may have to defend against intellectual property infringement claims, which could be expensive and, if we are not successful, could disrupt our business.

        Third parties may assert patent, trademark, copyright and other intellectual property rights to technologies that are important to us. In such an event, we may be required to incur significant costs in litigating a resolution to the asserted claims. The outcome of any litigation could require us to pay damages or obtain a license to a third party's proprietary rights in order to continue licensing our products as currently offered. If such a license is required, it might not be available on terms acceptable to us, if at all.

        Our software is complex and may contain undetected errors.

        Like many other complex software products, our software has on occasion contained undetected errors or "bugs." Because new releases of our software products are initially installed only by a selected group of customers, any errors or "bugs" in those new releases may not be detected for a number of months after the delivery of the software. These errors could result in loss of customers, harm to our reputation, adverse publicity, loss of revenues, delay in market acceptance, diversion of development resources, increased insurance costs or claims against us by customers.

        We may be subject to significant expenses and damages because of liability claims.

        The sale and implementation of certain of our software products and services, particularly in the areas of advanced process control and optimization, may entail the risk of product liability claims. Our software products and services are used in the design, operation and management of manufacturing processes at large facilities, and any failure of our software could result in significant claims against us for damages or for violations of environmental, safety and other laws and regulations. Our agreements with our customers generally contain provisions designed to limit our exposure to potential product liability claims. It is possible, however, that the limitation of liability provisions in our agreements may

36



not be effective as a result of federal, state or local laws or ordinances or unfavorable judicial decisions. A substantial product liability claim against us could harm our operating results and financial condition.

        Implementation of our products can be difficult and time-consuming, and customers may be unable to implement our products successfully or otherwise achieve the benefits attributable to our products.

        Our products are intended to work with complex business processes. Some of our software, such as customized scheduling applications and integrated supply chain products, must integrate with the existing computer systems and software programs of our customers. This can be complex, time-consuming and expensive. As a result, some customers may have difficulty in implementing or be unable to implement these products successfully or otherwise achieve the benefits attributable to these products. Customers may also make claims against us relating to the functionality, performance or implementation of this software. Delayed or ineffective implementation of the software products or related services may limit our ability to expand our revenues and may result in customer dissatisfaction, harm to our reputation and may result in customer unwillingness to pay the fees associated with these products.

        If we are not successful in our management transition or in attracting and retaining management team members and other highly qualified individuals in our industry, we may not be able to successfully implement our business strategy.

        Our ability to establish and maintain a position of technology leadership in the highly competitive e-business software market depends in large part upon our ability to attract and retain highly qualified managerial, sales and technical personnel. We have historically relied on the services of Lawrence B. Evans, our principal founder and our Chairman, President and Chief Executive Officer. On October 1, 2002, David L. McQuillin, became our Chief Executive Officer. McQuillin had been serving as one of our co-chief operating officer and had not previously served as the chief executive officer of a publicly traded corporation. Most of our executive officers have not entered into an employment agreement with us. In the future, we may experience the departure of other senior executives due to competition for talent from start-ups and other companies. Our future success depends on a successful management transition and will also depend on our continuing to attract, retain and motivate highly skilled employees. Competition for employees in our industry is intense. We may be unable to retain our key employees or attract, assimilate or retain other highly qualified employees in the future. We have from time to time in the past experienced, and we expect to continue to experience in the future, difficulty in hiring and retaining highly skilled employees with appropriate qualifications.

        Our common stock may experience substantial price and volume fluctuations.

        The equity markets have from time to time experienced extreme price and volume fluctuations, particularly in the high technology sector, and those fluctuations have often been unrelated to the operating performance of particular companies. In addition, factors such as our financial performance, announcements of technological innovations or new products by us or our competitors, as well as market conditions in the computer software or hardware industries, may have a significant impact on the market price of our common stock. Since April 5, 2002, the date on which we preliminarily announced our estimated results for the three months ended March 31, 2002, the price per share of our common stock, as reported by the Nasdaq National Market, decreased from $17.90 to a low of $0.59 on October 11, 2002. On February 10, 2003, the last reported sale price of our common stock on the Nasdaq National Market was $2.95.

        In the past, following periods of volatility in the market price of a public companies securities, securities class action litigation has often been instituted against companies. This type of litigation could result in substantial costs and a diversion of management's attention and resources.

37



        Our common stockholders may experience further dilution and the price of our common stock may decline as a result of our convertible preferred stock and common stock financings.

        In 2002, we issued convertible preferred stock, together with warrants to purchase 791,044 shares of common stock. We currently have outstanding 40,000 shares of Series B-I convertible preferred stock and 20,000 shares of Series B-II convertible preferred stock.

        Each share of Series B-I and B-II convertible preferred stock is convertible into a number of shares of common stock equal to the stated value, which initially is $1,000, divided by a conversion price of $19.97 in the case of the Series B-1 convertible preferred stock and $17.66 in the case of the Series B-2 convertible preferred stock, subject to antidilution and other adjustments for events affecting our capital structure. If we issue additional shares of common stock, or instruments convertible or exchangeable for common stock, at an effective net price less than the lesser of (a) $17.75, in the case of the Series B-I convertible preferred stock, or $15.69 in the case of the Series B-II convertible preferred stock and (b) the then-applicable conversion price for such series, the conversion price for that series will be reduced to equal that effective net price. These adjustments do not apply to the issuance of common stock or such instruments in specified firm commitment underwritten public offerings, strategic arrangements, mergers or acquisitions, and grants and purchases of securities pursuant to equity incentive plans.

        The Series B-I and B-II convertible preferred stock accrues dividends at an annual rate of 4% that is payable quarterly, commencing June 30, 2002, in either cash or common stock, at our option (subject to our satisfaction of specified conditions set forth in our charter). From August 6, 2003 until February 6, 2004, for the Series B-I convertible preferred stock, and from August 28, 2003 until February 17, 2004, for the Series B-II convertible preferred stock, holders may require that we redeem up to a total of 20,000 shares of Series B-I convertible preferred stock and 10,000 shares of Series B-II convertible preferred stock if the average closing price of the common stock for the 20 consecutive trading days immediately preceding August 7, 2003 and August 28, 2003, respectively, or any date thereafter is below the then-applicable conversion price. Beginning on February 8, 2004 and February 28, 2004, holders of Series B-I convertible preferred stock and Series B-II convertible preferred stock, respectively, may require that we redeem any or all of their shares. We will be required to redeem all of the then-outstanding Series B-I and B-II convertible preferred stock on February 7, 2009 at a price equal to the stated value plus all accrued but unpaid dividends. In each instance, the redemption price may be paid in cash, stock or both, at our option. The stock payment will consist of either common stock or Series C preferred stock, subject to our satisfaction of specified conditions set forth in our charter.

        In May 2002, we sold 4,166,665 shares of common stock, together with five-year warrants to purchase up to 750,000 shares of common stock, in a private placement. If we issue additional shares of common stock, or instruments convertible or exchangeable for common stock, in specified transactions at an effective net price less than the exercise price of any of the five-year warrants, then the exercise price of the warrants will be adjusted pursuant to a weighted average anti-dilution formula. As the result of these and other provisions, these warrants may be exercised at a price per share that may be less than the then-current market price of the stock, which may cause dilution to our existing common stockholders.

        As a result of these and other provisions of the Series B-I and B-II convertible preferred stock and the warrants issued in the preferred and common stock financings, the Series B-I and B-II convertible preferred stock may be converted, and the warrants may be exercised, at a price per share that may be less than the then-current market price of the common stock, which may cause substantial dilution to our existing common stockholders. If the conversion price of the Series B-I and B-II convertible preferred stock or the exercise price of the warrants decreases as a result of antidilution

38



provisions, the number of shares of common stock issuable in connection with any dividends conversion or redemption could increase significantly.

        As part of our obligations under these financings, we registered for public resale by the holders of the Series B-I and B-II convertible preferred stock and common stock issued in the financings a total of 13,776,392 shares of common stock, including shares issuable upon conversion of the Series B-I and B-II convertible preferred stock and exercise of the warrants and shares that may become issuable as a result of antidilution provisions. If all of these registered shares were to be issued (disregarding limitations on the right of a holder to acquire shares of common stock upon the conversion of Series B-I or B-II convertible preferred stock or the exercise of warrants if the conversion or exercise would result in this holder beneficially owning more than 4.99% of our outstanding common stock without first providing us proper notice), these shares would represent 35.3% shares of our common stock issued and outstanding as of February 10, 2003. Any sale of these shares of common stock into the public market could cause a decline in the trading price of our common stock.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

        Information relating to quantitative and qualitative disclosure about market risk is set forth under the caption "Notes to Consolidated Condensed Financial Statements," [2., 3. and 4.] and below under the captions "Investment Portfolio" and "Foreign Exchange Hedging."

Investment Portfolio

        We do not use derivative financial instruments in our investment portfolio. We place our investments in instruments that meet high credit quality standards, as specified in our investment policy guidelines; the policy also limits the amount of credit exposure to any one issuer and the types of instruments approved for investment. We do not expect any material loss with respect to our investment portfolio. The following table provides information about our investment portfolio. For investment securities, the table presents principal cash flows and related weighted average interest rates by expected maturity dates.

Impact of Foreign Currency Rate Changes

        During the first six months of fiscal 2003, the U.S. dollar generally weakened against Asia/Pacific and European currencies. The translation of the parent company's intercompany receivables and foreign entities assets and liabilities did not have a material impact on our consolidated results. Foreign exchange forward contracts are only purchased to hedge certain customer accounts and installment receivable amounts denominated in a foreign currency.

Foreign Exchange Hedging

        We enter into foreign exchange forward contracts to reduce our exposure to currency fluctuations on customer accounts receivables denominated in foreign currency. The objective of these contracts is

39



to neutralize the impact of foreign currency exchange rate movements on our operating results. We do not use derivative financial instruments for speculative or trading purposes. We had $7.9 million of foreign exchange forward contracts denominated in British, Japanese, Swiss, Netherlands, and Euro currencies, which represented underlying customer accounts receivable transactions at December 31, 2002. At each balance sheet date, the foreign exchange forward contracts and the related installments receivable denominated in foreign currency are revalued based on the current market exchange rates. Resulting gains and losses are included in earnings or deferred as a component of other comprehensive income. These deferred gains and losses are recognized in income in the period in which the underlying anticipated transaction occurs. Gains and losses related to these instruments for the six months ended December 31, 2002 were not material to our financial position. We do not anticipate any material adverse effect on our consolidated financial position, results of operations, or cash flows resulting from the use of these instruments. However, we cannot assure you that these strategies will be effective or that transaction losses can be minimized or forecasted accurately.

        The following table provides information about our foreign exchange forward contracts at December 31, 2002. The table presents the value of the contracts in U.S. dollars at the contract exchange rate as of the contract maturity date. The average contract rate approximates the weighted average contractual foreign currency exchange rate and the forward position in U.S. dollars approximates the fair value of the contract at December 31, 2002.

Item 4.    Controls and Procedures

        (a) Evaluation of disclosure controls and procedures.    Based on their evaluation of our disclosure controls and procedures (as defined in Rules 13a-14(c) and 15d-14(c) under the Securities Exchange Act of 1934) as of a date within 90 days of the filing date of this quarterly report, our chief executive officer and chief financial officer have concluded that our disclosure controls and procedures are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and are operating in an effective manner.

PART II. OTHER INFORMATION

Item 1.    Legal Proceedings

        By letter of June 7, 2002, the FTC informed us that it was conducting an investigation into the competitive effects of our recent acquisition of Hyprotech. We completed production of all requested documents in January 2003, are currently complying with deposition requests and expect to conclude our presentation to the FTC of our market analysis and supporting arguments for the acquisition in February 2003. We continue to cooperate fully with the FTC.

        We cannot be certain whether the FTC might seek any relief from us or the nature of any such relief that might be sought. The FTC may determine to challenge the acquisition through an administrative civil complaint seeking to declare the acquisition in violation of Section 7 of the Clayton Act or Section 5 of the FTC Act. If the FTC were to prevail in that challenge, it could seek to impose a wide variety of remedies, some of which may have a material adverse effect on our ability to continue to operate under our current business plans. These potential remedies include divestiture of Hyprotech, as well as mandatory licensing of Hyprotech software products and our other engineering software products to one or more of our competitors.

        On May 31, 2002, we acquired the capital stock of Hyprotech from AEA Technology plc. AEA is engaged in arbitration proceedings in England over a contract dispute with KBC Advanced Technologies PLC, an English technology and consulting services company. The dispute remains in arbitration and concerns the characterization of certain technology for purposes of calculating royalties, plus other contractual rights with respect to Hysys.Refinery. Hysys.Refinery was retained by AEA with support for Hysys.Refinery to be provided by Hyprotech pursuant to a contract with AEA. We indemnified AEA under the Sale and Purchase Agreement with AEA dated May 10, 2002 against any costs, damages or expenses in respect of a claim brought by KBC alleging damages due to AEA's (a) failure to comply with its contractual obligations after the acquisition, (b) breach of non-competition clauses with respect to activities occurring after the acquisition, (c) breach of certain obligations to KBC under its agreement by virtue of the acquisition, or (d) execution of the acquisition agreement.

        On September 11, 2002, we and Hyprotech were sued by KBC in state district court in Houston, Texas on issues related to the technology subject to review in the arbitration proceeding. KBC has requested actual and exemplary damages, costs and interest. We believe the causes of action to be without merit and will defend the case vigorously. We have filed a counterclaim against KBC requesting actual and punitive damages and attorney fees.

Item 2.    Changes in Securities and Use of Proceeds

        In accordance with the terms of our Series B preferred stock, on October 1, 2002 and January 2, 2003, we elected to issue to the holders of our Series B preferred stock a total of 189,468 and 196,971 shares of our common stock in payment of the dividends accrued in the amounts of $604,932 on our Series B preferred stock for the quarterly dividend periods ended September 30, 2002 and December 31, 2002, respectively.    The issuance of these dividend shares was made in reliance on Section 4(2) of the Securities Act of 1933, as amended, which provides an exemption from the registration provisions of the Securities Act for sales by an issuer not involving a public offering. We have registered these dividend shares for resale under the Securities Act on a shelf registration statement on Form S-3 (registration no. 333-90066).

Item 4.    Submission of Matters to a Vote of Security Holders

        We held our annual meeting of stockholders on December 10, 2002 to elect two directors to hold office until our 2005 annual meeting of stockholders. Proxies for the meeting were solicited in

41



accordance with Section 14(a) of the Securities Exchange Act pursuant to a proxy statement dated November 4, 2002. There was no solicitation in opposition to the persons nominated by the board of directors, and both of the board's nominees were elected. The votes cast by proxy or in person with respect to the election of directors, as determined by the final report of the inspectors, are set forth below. There were no broker non-votes with respect to either nominee.

SILICON VALLEY BANK LOAN AND SECURITY AGREEMENT BORROWER: ASPEN TECHNOLOGY, INC., A DELAWARE CORPORATION ADDRESS: TEN CANAL PARK CAMBRIDGE, MASSACHUSETTS 02141 BORROWER: ASPENTECH, INC., A TEXAS CORPORATION ADDRESS: TEN CANAL PARK CAMBRIDGE, MASSACHUSETTS 02141 BORROWER: HYPROTECH COMPANY, A CORPORATION ORGANIZED UNDER THE LAWS OF NOVA SCOTIA, CANADA ADDRESS: TEN CANAL PARK CAMBRIDGE, MASSACHUSETTS 02141 DATE: JANUARY 30, 2003 THIS LOAN AND SECURITY AGREEMENT is entered into on the above date between SILICON VALLEY BANK, a California-chartered bank, with its principal place of business at 3003 Tasman Drive, Santa Clara, California 95054 and with a loan production office located at One Newton Executive Park, Suite 200, 2221 Washington Street, Newton, Massachusetts 02462 ("Silicon") and the borrowers named above (jointly and severally, individually and collectively, "Borrower"), with offices located at the above address ("Borrower's Address"). The Schedule and Exhibits to this Agreement (the "Schedule" and the "Exhibits," respectively) shall for all purposes be deemed to be part of this Agreement, and the same are integral parts of this Agreement. (Definitions of certain terms used in this Agreement are set forth in Section 8 below.) 1. LOANS. 1.1 LOANS. Silicon will make loans to Borrower (the "Loans"), up to the amounts (the "Credit Limit") shown on the Schedule, provided no Default or Event of Default has occurred and is continuing, and subject to deduction of any Reserves for accrued interest and such other Reserves as Silicon (upon prior written notice to Borrower setting forth the basis of such deduction) deems proper from time to time. Amounts borrowed may be repaid and reborrowed during the term of this Agreement. 1.2 INTEREST. All Loans and all other monetary Obligations shall bear interest at the rate shown on the Schedule, except where expressly set forth to the contrary in this Agreement. Interest shall be payable monthly, on the last day of the month. Interest may, in Silicon's discretion, be charged to Borrower's loan account, and the same shall, after being due and payable, bear interest at the same rate as the other Loans. Silicon may, in its discretion, charge interest to Borrower's Deposit Accounts maintained with Silicon. 1.3 OVERADVANCES. If at any time or for any reason the total of all outstanding Loans and all other Obligations (other than pursuant to the Exim Agreement) exceeds the Credit Limit (an "Overadvance"), Borrower shall immediately pay the amount of the excess to Silicon, without notice or demand. Without limiting Borrower's obligation to repay to Silicon on demand the amount of any Overadvance, Borrower agrees to pay Silicon interest on the outstanding amount of any Overadvance, on demand, at a rate equal to the interest rate which would otherwise be applicable to the Overadvance, plus an additional two percent (2%) per annum. 1.4 FEES. Borrower shall pay Silicon the fees shown on the Schedule, which are in addition to all interest and other sums payable to Silicon and are not refundable.

SILICON VALLEY BANK LOAN AND SECURITY AGREEMENT - -------------------------------------------------------------------------------- 1.5 LETTERS OF CREDIT. In addition to Section 1.6 and Section 1.7, at the request of Borrower and provided no Default or Event of Default has occurred and is continuing, Silicon shall issue or arrange for the issuance of letters of credit for the account of Borrower, in each case in form and substance reasonably satisfactory to Silicon in its sole discretion (collectively, "Letters of Credit"). The aggregate undrawn amount of all outstanding Letters of Credit from time to time (plus all Silicon exposure under any foreign exchange contracts and Cash Management Services entered into under Sections 1.6 and 1.7 hereof) shall not exceed the amount shown on the Schedule (the "Letter of Credit Sublimit"), and shall be reserved against Loans which would otherwise be available hereunder. Each Letter of Credit may have an expiry date later than the Maturity Date provided, as further set forth in Section 6.2 hereof, Borrower's Letter of Credit reimbursement obligation shall be secured by cash (in such amounts as set forth in Section 6.2) on terms acceptable to Silicon on and after (i) the Maturity Date or (ii) the occurrence and continuance of an Event of Default hereunder. Borrower shall pay all customary bank charges (including charges of Silicon) for the issuance of Letters of Credit, including those charges described on the Schedule. Any payment by Silicon under or in connection with a draw on any Letter of Credit shall constitute a Loan hereunder on the date such payment is made. Borrower hereby agrees to indemnify, save, and hold Silicon harmless from any loss, cost, expense, or liability, including payments made by Silicon, reasonable expenses, and reasonable attorneys' fees incurred by Silicon arising out of or in connection with any Letters of Credit. Borrower agrees to be bound by the regulations and interpretations of the issuer of any Letters of Credit guarantied by Silicon and opened for Borrower's account or by Silicon's interpretations of any Letter of Credit issued by Silicon for Borrower's account, and Borrower understands and agrees that Silicon shall not be liable for any error, negligence, or mistake, whether of omission or commission, in following Borrower's instructions or those contained in the Letters of Credit or any modifications, amendments, or supplements thereto except any such arising out of the gross negligence or willful misconduct of Silicon or its agents. Borrower understands that Letters of Credit may require Silicon to indemnify the issuing bank for certain costs or liabilities arising out of claims by Borrower against such issuing bank. Borrower hereby agrees to indemnify and hold Silicon harmless with respect to any loss, cost, expense, or liability incurred by Silicon under any Letter of Credit as a result of Silicon's indemnification of any such issuing bank except any such arising out of the gross negligence or willful misconduct of Silicon or its agents. The provisions of this Loan Agreement, as it pertains to Letters of Credit, and any other present or future documents or agreements between Borrower and Silicon relating to Letters of Credit are cumulative. 1.6 FOREIGN EXCHANGE SUBLIMIT. In addition to Section 1.5 and Section 1.7, Borrower may use up to the amount set forth on the Schedule in connection with foreign exchange forward contracts with Silicon under which Borrower commits to purchase from or sell to Silicon a set amount of foreign currency more than one business day after the contract date (the "FX Contract"). Silicon shall subtract up to a maximum of 10% of the amount of each outstanding FX Contract from the foreign exchange sublimit (the "FX Reserve"). Silicon may terminate the FX Contracts if an Event of Default occurs. 1.7 CASH MANAGEMENT SERVICES SUBLIMIT. In addition to Section 1.5 and Section 1.6, Borrower may use up to the amount set forth on the Schedule for Cash Management Services. Such aggregate amounts utilized under the Cash Management Services Sublimit shall at all times reduce the amount otherwise available for Loans hereunder. Any amounts Silicon pays on behalf of Borrower or any amounts that are not paid by Borrower for any Cash Management Services will be treated as Loans hereunder and will accrue interest at the interest rate applicable to Loans. 1.8 DESIGNATION OF AGENT. Each Borrower hereby designates Aspen Technology, Inc. (the "Agent") as the agent of that Borrower to discharge the duties and responsibilities of the Agent as provided herein. 1.9 OPERATION OF AGREEMENT. (a) Except as otherwise permitted by Silicon or as directed by the Agent in writing, loans hereunder shall be requested solely by the Agent as agent for each Borrower. 2

SILICON VALLEY BANK LOAN AND SECURITY AGREEMENT - -------------------------------------------------------------------------------- (b) Any Loan which may be made by Silicon under this Agreement and which is directed to the Agent is received by the Agent in trust for the Borrowers. The Agent shall distribute the proceeds of any such Loan solely to, or for the benefit of, a Borrower in accordance with the terms of this Agreement. Each Borrower shall be directly indebted to Silicon for each Loan distributed to any Borrower by the Agent, together with all accrued interest thereon, as if that amount had been advanced directly by Silicon to a Borrower (whether or not the subject Loan was based upon the accounts and/or inventory or other assets of the Borrower which actually received such distribution), in addition to which each Borrower shall be liable to Silicon for all Obligations under this Agreement, whether or not the proceeds of the Loan are distributed to any particular Borrower. (c) Silicon shall have no responsibility to inquire as to the distribution of Loans made by Silicon through the Agent as described herein. 1.10 LOANS DIRECTLY TO BORROWER. (a) If, for any reason, and at any time during the term of this Agreement, (i) any Borrower, including the Agent, as agent for each Borrower, shall be unable to, or prohibited from carrying out the terms and conditions of this Agreement (as determined by Silicon in Silicon's reasonable discretion); or (ii) Silicon deems it inexpedient (in Silicon's reasonable discretion) to continue making Loans to or for the account of any particular Borrower, or to channel such loans and Loans through the Agent, then Silicon may make Loans directly to such Borrower as Silicon determines to be expedient. (b) Each Borrower shall remain liable to Silicon for the payment and performance of all Obligations (which payment and performance shall continue to be secured by all Collateral) notwithstanding any determination by Silicon to cease making Loans to or for the benefit of any Borrower. 1.11 CONTINUATION OF AUTHORITY OF AGENT. The authority of the Agent to request Loans on behalf of, and to bind, each Borrower, shall continue unless and until Silicon acts as provided in Section 1.10, above, or Silicon actually receives: (a) written notice of: (i) the termination of such authority, and (ii) the subsequent appointment of a successor Agent, which notice is executed by the respective Officers of each Borrower (other than the President of the Agent being replaced) then eligible for borrowing under this Agreement; and (b) written notice from the successor Agent (i) accepting such appointment; (ii) acknowledging that the removal and appointment has been effected by the respective Officers of each Borrower eligible for borrowing under the within Agreement; and (iii) acknowledging that from and after the date of appointment, the newly appointed Agent shall be bound by the terms hereof, and that as used herein, the term "Agent" shall mean and include the newly appointed Agent. 1.12 INDEMNIFICATION. The Agent and each Borrower respectively shall indemnify, defend, and save and hold Silicon harmless from and against any liabilities, claims, demands, reasonable expenses, or losses made against or suffered by Silicon on account of, or arising out of, this Agreement, Silicon's reliance upon Loan requests made by the Agent, or any other action taken by Silicon hereunder or under any of Silicon's various agreements with the Agent and/or any Borrower and/or any other person arising under this Agreement, except any such arising out of the gross negligence or willful misconduct of Silicon or its agents. 3

SILICON VALLEY BANK LOAN AND SECURITY AGREEMENT - -------------------------------------------------------------------------------- 2. SECURITY INTEREST. 2.1 SECURITY INTEREST. To secure the payment and performance of all of the Obligations when due, and the performance of each of the Borrower's duties under this Agreement and all documents executed in connection herewith, Borrower hereby grants to Silicon a continuing security interest in all of Borrower's interest in the following, whether now owned or hereafter acquired, and wherever located: All Inventory, Equipment, Payment Intangibles, Letter-of-Credit Rights, Supporting Obligations, Receivables, and General Intangibles, all of Borrower's Deposit Accounts, and all money, and all property now or at any time in the future in Silicon's possession (including claims and credit balances), and all proceeds (including proceeds of any insurance policies, proceeds of proceeds and claims against third parties), all products and all books and records related to any of the foregoing (all of the foregoing, together with all other property in which Silicon may now or in the future be granted a lien or security interest, is referred to herein, collectively, as the "Collateral"). Subject to this Section 2.1, Section 8 of the Schedule and the definition of Permitted Liens, the security interest granted herein shall be a first priority security interest in the Collateral. The Collateral may also be subject to Permitted Liens. Borrower may also maintain Deposit Accounts and securities accounts at other financial institutions in accordance with the Section 8 of the Schedule, Silicon may, while an Event of Default continues, place a "hold" on any Deposit Account pledged as collateral. Borrower is not a party to, nor is bound by, any material license or other material agreement with respect to which the Borrower is the licensee that prohibits or otherwise restricts Borrower from granting a security interest in Borrower's interest in such license or agreement or any other property. Without prior consent from Silicon, Borrower shall not enter into, or become bound by, any such license or agreement which is reasonably likely to have a material impact on Silicon's business or financial condition. Borrower shall take such steps as Silicon reasonably requests to obtain the consent of, or waiver by, any person whose consent or waiver is necessary for all such licenses or contract rights to be deemed "Collateral" and for Silicon to have a security interest in it that might otherwise be restricted or prohibited by law or by the terms of any such license or agreement, whether now existing or entered into in the future. Notwithstanding the foregoing, it is expressly acknowledged and agreed that the security interest created in this Agreement only with respect to Exim Eligible Foreign Accounts (as such terms are defined in the Exim Agreement) related thereto is subject to and subordinate to the security interest granted to Silicon in the Exim Agreement with respect to such Exim Eligible Foreign Accounts, but only to the extent any advances are actually made to the Borrower under the Exim Agreement based upon such Exim Eligible Foreign Accounts. If Borrower shall at any time, acquire a commercial tort claim in excess of $250,000, Borrower shall promptly notify Silicon in a writing signed by Borrower of the brief details thereof and grant to Silicon in such writing a security interest therein and in the proceeds thereof, all upon the terms of this Agreement, with such writing to be in form and substance satisfactory to Silicon. The Collateral, however, does not include Intellectual Property. Notwithstanding the foregoing, the Collateral shall include all accounts, license and royalty fees and other revenues, proceeds, or income arising out of or relating to any of the Intellectual Property. As used herein, (i) "Intellectual Property" means: any and all Copyrights, any and all trade secrets, and any and all intellectual property rights in computer software and computer software products now or hereafter existing, created, acquired or held, any and all design rights which may be available to Borrower now or hereafter existing, created, acquired or held, all Mask Works or similar rights available for the protection of semiconductor chips, all Patents; any Trademarks, all licenses or other rights to use any of the Copyrights, Patents, Trademarks, or Mask Works, and all amendments, extensions, renewals and extensions of any of the Copyrights, Trademarks, Patents, or Mask Works; (ii) "Copyrights" means any and all copyright rights, copyright applications, copyright registrations and like protections in each work of authorship and derivative work thereof, whether published or unpublished and whether or not the same also constitutes a trade secret, now or hereafter existing, created, acquired or held; (iii) "Mask Works" means all mask work or similar rights available for the protection of semiconductor chips, now owned or hereafter acquired; (iv) "Patents" means all patents, patent applications and like protections including without limitation improvements, divisions, continuations, renewals, reissues, extensions and continuations-in-part of the same and (v) "Trademarks" means any trademark and servicemark rights, whether registered or not, applications to register and registrations of the same and like protections, and the entire goodwill of the business of Borrower connected with and symbolized by such trademarks. Notwithstanding the foregoing, with respect to the shares of stock of Borrower's subsidiaries organized under a jurisdiction outside of the United States (each, a "Foreign Subsidiary"), the term Collateral shall include only 65% of the shares owned by Borrower in each such Foreign Subsidiary. Notwithstanding the foregoing, the Collateral shall not include the New Accenture Collateral. 4

SILICON VALLEY BANK LOAN AND SECURITY AGREEMENT - -------------------------------------------------------------------------------- 2.2. RELEASE OF CERTAIN COLLATERAL. Provided no Default then exists, Silicon agrees to enter into an amendment to this Agreement in form and substance reasonably satisfactory to Silicon and Borrower (the "Amendment") to modify the Collateral to a first priority security interest only on Borrower's Payment Intangibles, Receivables and proceeds thereof, upon Borrower's achievement of net income in excess of $2,500,000 per quarter for two (2) consecutive quarters. Any such modification of the Collateral shall only be effective upon execution of the Amendment by Silicon and Borrower. 2.3 ACCENTURE COLLATERAL Notwithstanding anything to the contrary contained in this Agreement, the Exim Agreement or the Negative Pledge Agreement, Silicon acknowledges that Accenture LLP ("Accenture") currently has a lien on certain of Borrower's personal property (the "Old Accenture Collateral") pursuant to the terms of the security agreement between Accenture and Borrower dated August 16, 2002, which lien secures not more than $8,000,000 (the "Accenture Debt"). Simultaneously with the execution of this Agreement, Borrower shall cause Accenture to release and terminate its lien on the Old Accenture Collateral and Borrower will grant to Accenture a lien on the New Accenture Collateral to secure the Accenture Debt. As used in this Agreement, "New Accenture Collateral" shall mean specific Receivables and the proceeds thereof with a face amount of not more than the lesser of (i) $13,415,000 or (ii) two (2) times the outstanding principal amount of the Accenture Debt, which Receivables (A) have been disclosed in writing to Silicon within five Business Days of giving such lien, (B) are not included for borrowing hereunder as an Eligible Receivable, and (C) do not, in any event, meet Minimum Eligibility Requirements hereunder. As further described in Section 2.1 hereof, the Collateral does not include the New Accenture Collateral; provided, however, after the Accenture Debt has been repaid, Borrower shall grant to Silicon a security interest in the New Accenture Collateral or such portion of the New Accenture Collateral that then exists. 3. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BORROWER. In order to induce Silicon to enter into this Agreement and to make Loans, Borrower represents and warrants to Silicon as follows, and Borrower covenants that the following representations will continue to be true, and that Borrower will at all times comply with all of the following covenants: 3.1 CORPORATE EXISTENCE AND AUTHORITY. Borrower, if a corporation, is and will continue to be, duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation. Borrower is and will continue to be qualified and licensed to do business in all jurisdictions in which any failure to do so would have a material adverse effect on Borrower taken as a whole. The execution, delivery and performance by Borrower of this Agreement, and all other documents contemplated hereby (i) have been duly and validly authorized, (ii) are enforceable against Borrower in accordance with their terms (except as enforcement may be limited by equitable principles and by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to creditors' rights generally), (iii) do not violate Borrower's articles or certificate of incorporation, Borrower's by-laws, or any law or any material agreement or instrument which is binding upon Borrower or its property, and (iv) do not constitute grounds for acceleration of any material indebtedness or obligation under any material agreement or instrument which is binding upon Borrower or its property. 3.2 NAME; TRADE NAMES AND STYLES. The name of Borrower set forth in the heading to this Agreement is its correct name. Listed on the Schedule are all prior names of Borrower and all of Borrower's present and prior trade names. Borrower shall give Silicon 30 days' prior written notice before changing its name or doing business under any other name. Borrower has complied, and will in the future comply, with all laws relating to the conduct of business under a fictitious business name. 3.3 PLACE OF BUSINESS; LOCATION OF COLLATERAL. The address set forth in the heading to this Agreement is Borrower's chief executive office. In addition, Borrower has places of business and Collateral is located only at the locations set forth on the Schedule except for Collateral in transit or Collateral which moves in the ordinary course of business. Borrower will give Silicon at least 30 days prior written notice before opening any additional place of business with assets with a value in excess of $500,000, changing its chief executive office, changing its state of formation or moving any of the Collateral in excess of $500,000 to a location other than Borrower's Address or one of the locations set forth on the Schedule, except for Collateral in transit or Collateral which moves in the ordinary course of business. 5

SILICON VALLEY BANK LOAN AND SECURITY AGREEMENT - -------------------------------------------------------------------------------- 3.4 TITLE TO COLLATERAL; PERMITTED LIENS. Borrower is now, and will at all times in the future be, the sole owner of all the Collateral, except for items of Equipment which are leased by Borrower and except as otherwise permitted hereunder. The Collateral now is and will remain free and clear of any and all liens, charges, security interests, encumbrances and adverse claims, except for Permitted Liens. Silicon now has, and will continue to have, a first-priority perfected and enforceable security interest in all of the Collateral, subject only to the Permitted Liens and Deposit Accounts and securities accounts held at other financial institutions in accordance with Section 8 of the Schedule, and Borrower will at all times defend Silicon and the Collateral against all material claims of others. None of the Collateral now is or will be affixed to any real property in such a manner, or with such intent, as to become a fixture, other than trade fixtures. Borrower is not and will not become a lessee under any real property lease pursuant to which the lessor may obtain any rights in any of the Collateral and no such lease to which Borrower is a party as of the date hereof prohibits, restrains, impairs or will prohibit, restrain or impair Borrower's right to remove any Collateral from the leased premises. Whenever any Collateral is located upon premises in which any third party has an interest (whether as owner, mortgagee, beneficiary under a deed of trust, lien or otherwise), Borrower shall, whenever requested by Silicon, use its reasonable efforts to cause such third party to execute and deliver to Silicon, in form acceptable to Silicon, such waivers and subordinations as Silicon shall specify, so as to ensure that Silicon's rights in the Collateral are, and will continue to be, superior to the rights of any such third party. Borrower, subject to its reasonable commercial judgment, will keep in full force and effect, and will comply with all the material terms of, any lease of real property where any of the Collateral now or in the future may be located. All of Borrower's subsidiaries' assets are now and will hereafter remain free and clear of any and all liens, charges, security interests, encumbrances and adverse claims, other than Permitted Liens; provided, however, (i) AspenTech UK Limited may incur liens on substantially all of its assets, provided such liens shall secure not more than the principal amount of $5,000,000 and (ii) other non-Borrower subsidiaries may incur other liens which secure not more than $3,000,000 in the aggregate. 3.5 MAINTENANCE OF COLLATERAL. Borrower will maintain the Collateral in good working condition, and Borrower will not use the Collateral for any unlawful purpose. Borrower will immediately advise Silicon in writing of any material loss or damage to the Collateral. 3.6 BOOKS AND RECORDS. Borrower has maintained and will maintain at Borrower's Address complete and accurate books and records, comprising an accounting system in accordance with generally accepted accounting principles. Notwithstanding the foregoing, Borrower may move its books and records older than 1 year to an off-site storage facility. 3.7 FINANCIAL CONDITION, STATEMENTS AND REPORTS. All financial statements now or in the future delivered to Silicon have been, and will be, prepared in conformity with generally accepted accounting principles and now and in the future will completely and accurately reflect the financial condition of Borrower as required by GAAP, at the times and for the periods therein stated. Between the last date covered by any such statement provided to Silicon and the date hereof, there has been no material adverse change in the financial condition or business of Borrower taken as a whole. Borrower is solvent taken as a whole. 3.8 TAX RETURNS AND PAYMENTS; PENSION CONTRIBUTIONS. Borrower has timely filed (or timely filed extensions thereof), and will timely file, all material tax returns required by foreign, federal, state and local law, and Borrower has timely paid, and will timely pay, all foreign, federal, state and local taxes, assessments, deposits and contributions now or in the future owed by Borrower. Borrower may, however, defer payment of any contested taxes, provided that Borrower (i) in good faith contests Borrower's obligation to pay the taxes by appropriate proceedings promptly and diligently instituted and conducted, (ii) notifies Silicon in writing of the commencement of, and any material development in, the proceedings, and (iii) posts bonds or takes any other steps required to keep the contested taxes from becoming a lien upon any of the Collateral. Borrower is unaware of any claims or adjustments proposed for any of Borrower's prior tax years which could result in additional taxes in excess of 6

SILICON VALLEY BANK LOAN AND SECURITY AGREEMENT - -------------------------------------------------------------------------------- $750,000 becoming due and payable by Borrower. Borrower has paid, and shall continue to pay all amounts necessary to fund all present and future pension, profit sharing and deferred compensation plans in accordance with their terms or applicable law, and Borrower has not and will not withdraw from participation in, permit partial or complete termination of, or permit the occurrence of any other event with respect to, any such plan which could reasonably be expected to result in any liability of Borrower in excess of $500,000, including any liability to the Pension Benefit Guaranty Corporation or its successors or any other governmental agency. Borrower shall, at all times, utilize the services of an outside payroll service providing for the automatic deposit of all payroll taxes payable by Borrower. 3.9 COMPLIANCE WITH LAW. Except as disclosed in the Schedule, Borrower has complied, and will comply, in all material respects, with all provisions of all foreign, federal, state and local laws and regulations relating to Borrower, including, but not limited to, those relating to Borrower's ownership of real or personal property, the conduct and licensing of Borrower's business, and all environmental matters. 3.10 LITIGATION. Except as disclosed in the Schedule, there is no claim, suit, litigation, proceeding or investigation pending or (to best of Borrower's knowledge) threatened by or against or affecting Borrower in any court or before any governmental agency (or any basis therefor known to Borrower) which may result, either separately or in the aggregate, in any material adverse change in the financial condition or business of Borrower, or in any material impairment in the ability of Borrower to carry on its business in substantially the same manner as it is now being conducted. Borrower will promptly inform Silicon in writing of any claim, proceeding, litigation or investigation in the future threatened or instituted by or against Borrower involving any single claim of $250,000 or more, or involving $1,500,000 or more in the aggregate. 3.11 USE OF PROCEEDS. All proceeds of all Loans shall be used solely for working capital purposes of Borrower and its subsidiaries. Borrower is not purchasing or carrying any "margin stock" (as defined in Regulation U of the Board of Governors of the Federal Reserve System) and no part of the proceeds of any Loan will be used to purchase or carry any "margin stock" or to extend credit to others for the purpose of purchasing or carrying any "margin stock." 3.12 WITHHOLDING FOR HYPROTECH COMPANY. In the event any payments are received by Silicon from Hyprotech Company (the "Cdn Borrower") hereunder such payments will be made subject to applicable withholding for any taxes, levies, fees, deductions, withholding, restrictions or conditions of any nature whatsoever. Specifically, if at any time any governmental authority, applicable law, regulation or international agreement requires the Cdn Borrower to make any such withholding or deduction from any such payment or other sum payment hereunder to Silicon, the Cdn Borrower hereby covenants and agrees that the amount due from the Cdn Borrower with respect to such payment or other sum payable hereunder will be increased to the extent necessary to ensure that, after the making of such required withholding or deduction, Silicon receives a net sum equal to the sum which it would have received had no withholding or deduction been required and the Cdn Borrower shall pay the full amount withheld or deducted to the relevant governmental authority. The Cdn Borrower will, upon request, furnish Silicon with proof satisfactory to Silicon indicating that the Cdn Borrower has made such withholding payment provided, however, that the Cdn Borrower need not make any withholding payment if the amount or validity of such withholding payment is contested in good faith by appropriate and timely proceedings and as to which payment in full is bonded or reserved against by the Cdn Borrower. The agreements and obligations of the Cdn Borrower contained in this Section shall survive the Maturity Date. 4. RECEIVABLES. 4.1 REPRESENTATIONS RELATING TO RECEIVABLES. To the best of Borrower's knowledge after due inquiry, Borrower represents and warrants to Silicon as follows: Each Receivable with respect to which Loans are requested by Borrower shall, on the date each Loan is requested and made, (i) represents an undisputed (except to the extent that any disputed portion is excluded from such Receivable in determining Minimum Eligibility Requirements) bona fide existing unconditional obligation of the Account Debtor created by the sale, delivery, and acceptance of goods or the rendition of services in the ordinary course of Borrower's business, and (ii) meets the Minimum Eligibility Requirements set forth in Section 8 below. 7

SILICON VALLEY BANK LOAN AND SECURITY AGREEMENT - -------------------------------------------------------------------------------- 4.2 REPRESENTATIONS RELATING TO DOCUMENTS AND LEGAL COMPLIANCE. Borrower represents and warrants to Silicon as follows: All statements made and all unpaid balances appearing in all invoices, instruments and other documents evidencing the Receivables are and shall be true and correct in all material respects and all such invoices, instruments and other documents and all of Borrower's books and records are and shall be genuine and in all respects what they purport to be, and, to Borrower's knowledge, all signatories and endorsers have the capacity to contract. All sales and other transactions underlying or giving rise to each Receivable shall fully comply with all material applicable laws and governmental rules and regulations. All signatures and endorsements on all documents, instruments, and agreements relating to all Receivables are and shall, to the best of Borrower's knowledge, be genuine, and all such documents, instruments and agreements are and shall be legally enforceable in accordance with their terms (subject to the laws affecting creditors generally). 4.3 SCHEDULES AND DOCUMENTS RELATING TO RECEIVABLES. Borrower shall deliver to Silicon transaction reports and loan requests and schedules of all Receivables, and schedules of collections, all on Silicon's standard forms, in accordance with Section 5.3 and Section 6 of the Schedule; provided, however, that Borrower's failure to execute and deliver the same shall not affect or limit Silicon's security interest and other rights in all of Borrower's Receivables, nor shall Silicon's failure to advance or lend against a specific Receivable affect or limit Silicon's security interest and other rights therein. In the event Borrower has elected to be on "non-borrowing reporting status" (see Section 6 of the Schedule), Borrower shall furnish Silicon with a Loan request at least fifteen (15) days prior to the requested funding date. Otherwise, Loan requests received after 12:00 Noon will not be considered by Silicon until the next Business Day. Upon Silicon's request, together with each such schedule, or later if requested by Silicon, Borrower shall furnish Silicon with copies (or, at Silicon's request, originals) of all contracts, orders, invoices, and other similar documents, and all original shipping instructions, delivery receipts, bills of lading, and other evidence of delivery, for any goods the sale or disposition of which gave rise to such Receivables, and Borrower warrants the genuineness of all of the foregoing. Borrower shall also furnish to Silicon an aged accounts receivable trial balance in such form and at such intervals as Silicon shall reasonably request. In addition, upon Silicon's request, Borrower shall deliver to Silicon the originals of all instruments, chattel paper, security agreements, guarantees and other documents and property evidencing or securing any Receivables, immediately upon receipt thereof and in the same form as received, with all necessary indorsements, all of which shall be with recourse. Upon Silicon's request, Borrower shall also provide Silicon with copies of all credit memos. 4.4 COLLECTION OF RECEIVABLES. Borrower shall cause the Account Debtors to remit all Receivables owned by Borrower to Silicon and Silicon shall hold all payments on, and proceeds of, Receivables in a lockbox account, or such other "blocked account" as Silicon may specify, pursuant to a blocked account agreement in such form as Silicon may reasonably require. All such payments on, and proceeds of, Receivables shall be first applied to the Obligations in such order as Silicon shall determine, with the excess, if any, deposited on a daily basis into an operating account of Borrower with Silicon. Silicon or its designee may, at any time (i) after the occurrence and continuance of a Default or (ii) in connection with verifications as described in Section 4.8, notify Account Debtors that the Receivables are subject to the security interest of Silicon. Notwithstanding the foregoing, proceeds of Receivables owing to Hyprotech (the "Hyprotech Receivables"), at Borrower's option, shall not be subject to this Section 4.4 regarding a lockbox account or other "blocked account"; provided, however, if the Hyprotech Receivables are not remitted to Silicon in accordance with this Section 4.4, the Hyprotech Receivables shall not be deemed to meet Minimum Eligibility Requirements (as described in the definition of Eligible Receivable in Section 8 hereof). 4.5. REMITTANCE OF PROCEEDS. All proceeds arising from the disposition of any Collateral shall be delivered, in kind, by Borrower to Silicon in the original form in which received by Borrower not later than three (3)Business Days after receipt by Borrower, to be first applied to the Obligations in such order as Silicon shall determine, with the excess, if any, to be deposited on a daily basis into an operating account of Borrower with 8

SILICON VALLEY BANK LOAN AND SECURITY AGREEMENT - -------------------------------------------------------------------------------- Silicon; provided that, if no Default or Event of Default has occurred and is continuing, Borrower shall not be obligated to remit to Silicon the proceeds of the sale of worn out or obsolete equipment disposed of by Borrower in good faith in an arm's length transaction for an aggregate purchase price of $750,000 or less (for all such transactions in any fiscal year). Until forwarded to Silicon, Borrower agrees that it will hold the proceeds of the sale of Collateral received directly by Borrower separate and apart from such other funds and property and in an express trust for Silicon. Nothing in this Section 4.5 limits the restrictions on disposition of Collateral set forth elsewhere in this Agreement. 4.6 DISPUTES. Borrower shall notify Silicon promptly of all disputes or claims relating to Receivables owned by Borrower involving amounts in excess of $500,000. Borrower shall not forgive (completely or partially), compromise or settle any Receivable for less than payment in full, or agree to do any of the foregoing, except that Borrower may do so, provided that: (i) Borrower does so in good faith, in a commercially reasonable manner, in the ordinary course of business, and in arm's length transactions, which are reported to Silicon on the regular reports provided to Silicon; (ii) no Default or Event of Default has occurred and is continuing; and (iii) taking into account all such discounts settlements and forgiveness, the total outstanding Loans will not exceed the Credit Limit. Silicon may, at any time after the occurrence and continuance of an Event of Default, settle or adjust disputes or claims directly with Account Debtors for amounts and upon terms which Silicon considers advisable in its reasonable credit judgment and, in all cases, Silicon shall credit Borrower's Loan account with only the net amounts received by Silicon in payment of any Receivables. 4.7 RETURNS. Provided no Event of Default has occurred and is continuing, if any Account Debtor returns any Inventory to Borrower in the ordinary course of its business, Borrower shall promptly determine the reason for such return and promptly issue a credit memorandum to the Account Debtor in the appropriate amount (sending a copy to Silicon upon Silicon's request). In the event any attempted return occurs after the occurrence and continuance of any Event of Default, Borrower shall (i) hold the returned Inventory in trust for Silicon, (ii) segregate all returned Inventory from all of Borrower's other property, (iii) conspicuously label the returned Inventory as Silicon's property, and (iv) immediately notify Silicon of the return of any Inventory, specifying the reason for such return, the location and condition of the returned Inventory, and on Silicon's request deliver such returned Inventory to Silicon. 4.8 VERIFICATION. Silicon may, from time to time, verify directly with the respective Account Debtors the validity, amount and other matters relating to the Receivables, by means of mail, telephone or otherwise, either in the name of Borrower or Silicon or such other name as Silicon may choose. 4.9 NO LIABILITY. Silicon shall not under any circumstances be responsible or liable for any shortage or discrepancy in, damage to, or loss or destruction of, any goods, the sale or other disposition of which gives rise to a Receivable, or for any error, act, omission, or delay of any kind occurring in the settlement, failure to settle, collection or failure to collect any Receivable, or for settling any Receivable in good faith for less than the full amount thereof, nor shall Silicon be deemed to be responsible for any of Borrower's obligations under any contract or agreement giving rise to a Receivable. Nothing herein shall, however, relieve Silicon from liability for its own gross negligence or willful misconduct. 5. ADDITIONAL DUTIES OF THE BORROWER. 5.1 FINANCIAL AND OTHER COVENANTS. Borrower shall at all times comply with the financial and other covenants set forth in the Schedule. 5.2 INSURANCE. Borrower shall, at all times insure all of the tangible personal property Collateral and carry such other business insurance, with insurers reasonably acceptable to Silicon, in such form and amounts as Silicon may reasonably require having regard to comparable businesses, and Borrower shall provide evidence of such insurance to Silicon, so that Silicon is reasonably satisfied that such insurance is, at all times, in full force and effect. 9

SILICON VALLEY BANK LOAN AND SECURITY AGREEMENT - -------------------------------------------------------------------------------- All such insurance policies shall name Silicon as an additional loss payee, and shall contain a lenders loss payee endorsement in form reasonably acceptable to Silicon. Upon receipt of the proceeds of any such insurance, Silicon shall apply such proceeds in reduction of the Obligations as Silicon shall determine in its sole discretion, except that, provided no Default or Event of Default has occurred and is continuing, Silicon shall release to Borrower insurance proceeds totaling less than $500,000 in aggregate during the term of this Agreement, which shall be utilized by Borrower for the replacement or repair of the Collateral with respect to which the insurance proceeds were paid. Silicon may require reasonable assurance that the insurance proceeds so released will be so used. If Borrower fails to provide or pay for any insurance, Silicon may, but is not obligated to, obtain the same at Borrower's expense. Borrower shall promptly deliver to Silicon copies of all material reports made to insurance companies. 5.3 REPORTS. Borrower, at its expense, shall provide Silicon with the written reports set forth in the Schedule, and such other written reports with respect to Borrower (including budgets, sales projections, operating plans and other financial documentation), as Silicon shall from time to time reasonably specify. 5.4 ACCESS TO COLLATERAL, BOOKS AND RECORDS. At reasonable times, and on one Business Day's notice, Silicon, or its agents, shall have the right to inspect the Collateral, and the right to audit and copy Borrower's books and records. Silicon shall take reasonable steps to keep confidential all information obtained in any such inspection or audit, but Silicon shall have the right to disclose any such information to its auditors, regulatory agencies, and attorneys on a confidential basis, and pursuant to any subpoena or other legal process. The foregoing inspections and audits shall be at Borrower's expense (provided, however, Silicon shall conduct no more than four (4) such audits in any calendar year prior to the occurrence and during the continuance of an Event of Default) and the charge therefor shall be $750 per person per day (or such higher amount as shall represent Silicon's then current standard charge for the same), plus reasonable out of pocket expenses. Except as permitted pursuant to Section 3.6 hereof, Borrower will not enter into any agreement with any accounting firm, service bureau or third party to store Borrower's books or records at any location other than Borrower's Address, without first obtaining Silicon's written consent, which may be conditioned upon such accounting firm, service bureau or other third party agreeing to give Silicon the same rights with respect to access to books and records and related rights as Silicon has under this Loan Agreement. 5.5 NEGATIVE COVENANTS. Borrower shall not, without Silicon's prior written consent, do any of the following: (i) merge or consolidate with another corporation or entity; provided, however, upon prior notice to Silicon, any Borrower, or any subsidiary of any Borrower, may merge into, or consolidate with, a Borrower (provided a Borrower is the surviving legal entity); (ii) acquire any assets or stock of another Person valued in excess of $5,000,000 in the aggregate in any calendar year, except in the ordinary course of business; (iii) enter into any other transaction outside the ordinary course of business (other than with respect to Permitted Transfers or as otherwise permitted hereunder); (iv) sell or transfer any Collateral other than Permitted Transfers; (v) store any Inventory or other Collateral in excess of $500,000 with any warehouseman or other third party except as permitted pursuant to Sections 3.3 and 3.6 hereof); (vi) sell any Inventory on a sale-or-return, guaranteed sale, consignment, or other contingent basis; (vii) make any loans of any money or other assets other than loans and advances to or for the benefit of Borrower's subsidiaries in amounts not to exceed the lesser of (A) the usual and necessary operating expenses of its subsidiaries or (B) $10,000,000 per fiscal quarter of the Agent; provided, however, each Borrower may make unlimited intercompany loans or advances to, or for the benefit of, any other Borrower; (viii) incur any debts outside the ordinary course of business except as permitted hereunder; (ix) guarantee or otherwise become liable with respect to the obligations of another party or entity, provided, however, Borrower may guarantee the debts and performance obligations of its subsidiaries on an unsecured basis in amounts equal to or less than $8,000,000 in the aggregate amount outstanding at any time; (x) pay or declare any dividends on Borrower's stock (except for dividends payable solely in stock of Borrower), provided, however, Borrower may make cash dividends pursuant to the terms of Borrower's Series B Preferred Stock provided that at the time of such payment there is then no Event of Default continuing, or would be continuing after giving effect to such payment; (xi) redeem, retire, purchase or otherwise acquire, directly or indirectly, any of Borrower's stock, and/or any of Borrower's 5 1/4% Convertible Subordinated Debentures or other subordinated debt instruments; provided, however, Borrower may (A) make cash repurchases of Borrower's Series B Preferred Stock pursuant to the terms of Borrower's Series B 10

SILICON VALLEY BANK LOAN AND SECURITY AGREEMENT - -------------------------------------------------------------------------------- Preferred Stock and (B) redeem, retire, purchase or acquire, directly or indirectly, any of Borrower's 5 1/4% Convertible Subordinated Debentures pursuant to the terms of the Indenture, provided that at the time of such payment, redemption, retirement, acquisition or purchase there is then no Event of Default continuing, or would be continuing after giving effect to such payment, redemption, retirement, acquisition or purchase; (xii) make any change in Borrower's capital structure which would have a material adverse effect on Borrower or on the prospect of repayment of the Obligations; or (xiii) dissolve or elect to dissolve. Transactions permitted by the foregoing provisions of this Section 5.5 are only permitted if no Default or Event of Default would occur as a result of such transaction. 5.6 LITIGATION COOPERATION. Should any third-party suit or proceeding be instituted by or against Silicon with respect to any Collateral or in any manner relating to Borrower, Borrower shall, without expense to Silicon, make available Borrower and its officers, employees and agents and Borrower's books and records, to the extent that Silicon may deem them reasonably necessary in order to prosecute or defend any such suit or proceeding. Any confidential information shall be treated as such by Silicon pursuant to Section 9.20 hereof. 5.7 FURTHER ASSURANCES. Borrower agrees, at its expense, on request by Silicon, to execute all documents and take all actions, as Silicon may deem reasonably necessary or useful in order to perfect and maintain Silicon's perfected security interest in the Collateral, and in order to fully consummate the transactions contemplated by this Agreement. 6. TERM. 6.1 MATURITY DATE. This Agreement shall continue in effect until the maturity date set forth on the Schedule (the "Maturity Date"); provided that the Maturity Date may be extended upon written agreement of the parties hereto. Subject to the cancellation fees set forth in Section 3 of the Schedule, Borrower may terminate this Agreement at any time upon three (3) business days' notice to Silicon. 6.2 PAYMENT OF OBLIGATIONS. On the Maturity Date or on any earlier effective date of termination, Borrower shall pay and perform in full all Obligations, whether evidenced by installment notes or otherwise, and whether or not all or any part of such Obligations are otherwise then due and payable. Without limiting the generality of the foregoing, if on the Maturity Date, or on any earlier effective date of termination, there are any outstanding Letters of Credit issued by Silicon or issued by another institution based upon an application, guarantee, indemnity or similar agreement on the part of Silicon, then on such date Borrower shall provide to Silicon cash collateral in an amount equal to 100% of the undrawn amount of all such Letters of Credit plus all interest, fees and cost due or to become due in connection therewith, to secure all of the Obligations relating to said Letters of Credit, pursuant to Silicon's then standard form cash pledge agreement. Notwithstanding any termination of this Agreement, all of Silicon's security interests in all of the Collateral and all of the terms and provisions of this Agreement shall continue in full force and effect until all Obligations have been paid and performed in full; provided that, without limiting the fact that Loans are subject to the discretion of Silicon, Silicon may, in its sole discretion, refuse to make any further Loans after termination. No termination shall in any way affect or impair any right or remedy of Silicon, nor shall any such termination relieve Borrower of any Obligation to Silicon, until all of the Obligations have been paid and performed in full. Upon payment and performance in full of all the Obligations and the termination of Silicon's commitment to lend hereunder, Silicon shall promptly deliver to Borrower termination statements, requests for reconveyances and such other documents as may be required to fully terminate Silicon's security interests. 11

SILICON VALLEY BANK LOAN AND SECURITY AGREEMENT - -------------------------------------------------------------------------------- 7. EVENTS OF DEFAULT AND REMEDIES. 7.1 EVENTS OF DEFAULT.

All proceeds realized as the result of any sale of the Collateral shall be applied by Silicon first to the reasonable costs, expenses, liabilities, obligations and attorneys' fees incurred by Silicon in the exercise of its rights under this Agreement, second to the interest due upon any of the Obligations, and third to the principal of the Obligations, in such order as Silicon shall determine in its sole discretion. Any surplus shall be paid to Borrower or other persons legally entitled thereto; Borrower shall remain liable to Silicon for any deficiency. If, Silicon, in its sole discretion, directly or indirectly enters into a deferred payment or other credit transaction with any purchaser at any sale of Collateral, Silicon shall have the option, subject always to commercial reasonableness, exercisable at any time, in its sole discretion, of either reducing the Obligations by the principal amount of purchase price or deferring the reduction of the Obligations until the actual receipt by Silicon of the cash therefor. 7.6 REMEDIES CUMULATIVE. In addition to the rights and remedies set forth in this Agreement, Silicon shall have all the other rights and remedies accorded a secured party under the Massachusetts Uniform Commercial Code and under all other applicable laws, and under any other instrument or agreement now or in the future entered into between Silicon and Borrower, and all of such rights and remedies are cumulative and none is exclusive. Exercise or partial exercise by Silicon of one or more of its rights or remedies shall not be deemed an election, nor bar Silicon from subsequent exercise or partial exercise of any other rights or remedies.

Borrower waives demand, protest, notice of protest and notice of default or dishonor, notice of payment and nonpayment, release, compromise, settlement, extension or renewal of any commercial paper, instrument, account, General Intangible, document or guaranty at any time held by Silicon on which Borrower is or may in any way be liable, and notice of any action taken by Silicon, unless expressly required by this Agreement. 19

SILICON VALLEY BANK LOAN AND SECURITY AGREEMENT - -------------------------------------------------------------------------------- 9.9 NO LIABILITY FOR ORDINARY NEGLIGENCE. Neither Silicon, nor any of its directors, officers, employees, agents, attorneys or any other Person affiliated with or representing Silicon shall be liable for any claims, demands, losses or damages, of any kind whatsoever, made, claimed, incurred or suffered by Borrower or any other party through the ordinary negligence of Silicon, or any of its directors, officers, employees, agents, attorneys or any other Person affiliated with or representing Silicon, but nothing herein shall relieve Silicon from liability for its own gross negligence or willful misconduct. 9.10 AMENDMENT. The terms and provisions of this Agreement may not be waived or amended, except in a writing executed by Borrower and a duly authorized officer of Silicon. 9.11 TIME OF ESSENCE. Time is of the essence in the performance by Borrower of each and every obligation under this Agreement. 9.12 ATTORNEYS FEES AND COSTS. Borrower shall reimburse Silicon for all reasonable attorneys' fees and all filing, recording, search, title insurance, appraisal, audit, and other reasonable costs incurred by Silicon, pursuant to, or in connection with, or relating to this Agreement (whether or not a lawsuit is filed), including, but not limited to, any reasonable attorneys' fees and costs Silicon incurs in order to do the following: prepare and negotiate this Agreement and the documents relating to this Agreement; obtain legal advice in connection with this Agreement or Borrower; enforce, or seek to enforce, any of its rights; prosecute actions against, or defend actions by, Account Debtors; commence, intervene in, or defend any action or proceeding; initiate any complaint to be relieved of the automatic stay in bankruptcy; file or prosecute any probate claim, bankruptcy claim, third-party claim, or other claim; examine, audit, copy, and inspect any of the Collateral or any of Borrower's books and records; protect, obtain possession of, lease, dispose of, or otherwise enforce Silicon's security interest in, the Collateral; and otherwise represent Silicon in any litigation relating to Borrower. In satisfying Borrower's obligation hereunder to reimburse Silicon for such attorneys fees, Borrower may, for convenience, issue checks directly to Silicon's attorneys, Riemer & Braunstein, LLP, but Borrower acknowledges and agrees that Riemer & Braunstein, LLP is representing only Silicon and not Borrower in connection with this Agreement. If either Silicon or Borrower files any lawsuit against the other predicated on a breach of this Agreement, Silicon shall be entitled to recover its reasonable costs and attorneys' fees, including (but not LIMITED to) reasonable attorneys' fees and costs incurred in the enforcement of, execution upon or defense of any order, decree, award or judgment.

The provisions of this Agreement shall be binding upon and inure to the benefit of the respective successors, assigns, heirs, beneficiaries and representatives of Borrower and Silicon; provided, however, that Borrower may not assign or transfer any of its rights under this Agreement without the prior written consent of Silicon, and any prohibited assignment shall be void. No consent by Silicon to any assignment shall release Borrower from its liability for the Obligations. 9.14 JOINT AND SEVERAL LIABILITY. If Borrower consists of more than one Person, their liability shall be joint and several, and the compromise of any claim with, or the release of, any Borrower shall not constitute a compromise with, or a release of, any other Borrower. 9.15 LIMITATION OF ACTIONS. Any claim or cause of action by Borrower against Silicon, its directors, officers, employees, agents, accountants or attorneys, based upon, arising from, or relating to this Loan Agreement shall be barred unless asserted by Borrower by the commencement of an action or proceeding in a court of competent jurisdiction by the filing of a complaint within the earlier to occur of (i) one year after the discovery of the act, occurrence or omission upon which such claim or cause of action is based, and the service of a summons and complaint on an officer of Silicon, or on any other person authorized to accept service on behalf of Silicon, within thirty (30) days thereafter, or (ii) two years from the date of this Agreement, or if later, two years from the date of any amendment or modification of this Agreement which extends the Maturity Date.

The period provided herein shall not be waived, tolled, or extended except by the written consent of Silicon in its sole discretion. This provision shall survive any termination of this Loan Agreement or any other present or future agreement. 20

At any time after the occurrence and during the continuance of an Event of Default, without demand or notice, Silicon may set off the same or any part thereof and apply the same to any liability or obligation of Borrower and any guarantor then due and regardless of the adequacy of any other collateral securing the loan. ANY AND ALL RIGHTS TO REQUIRE SILICON TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURES THE LOAN, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS, OR OTHER PROPERTY OF THE BORROWER OR ANY GUARANTOR, ARE HEREBY KNOWINGLY, VOLUNTARILY, AND IRREVOCABLY WAIVED. 9.17 SECTION HEADINGS; CONSTRUCTION. Section headings are only used in this Agreement for convenience. Borrower and Silicon acknowledge that the headings may not describe completely the subject matter of the applicable section, and the headings shall not be used in any manner to construe, limit, define or interpret any term or provision of this Agreement. The term "including", whenever used in this Agreement, shall mean "including (but not limited to)". This Agreement has been fully reviewed and negotiated between the parties and no uncertainty or ambiguity in any term or provision of this Agreement shall be construed strictly against Silicon or Borrower under any rule of construction or otherwise. 9.18 GOVERNING LAW; JURISDICTION; VENUE. This Agreement and all acts and transactions hereunder and all rights and obligations of Silicon and Borrower shall be governed by the laws of the Commonwealth of Massachusetts.

In handling any confidential information, Silicon shall exercise the same degree of care that it exercises for its own proprietary information, but disclosure of information may be made: (i) to Silicon's subsidiaries or affiliates in connection with their present or prospective business relations with Borrower (provided such subsidiaries or affiliates shall comply with comparable confidentiality provisions); (ii) to prospective transferees or purchasers of any interest in the Loans (provided such transferees or purchasers shall comply with comparable confidentiality provisions); (iii) as required by law, regulation, subpoena, or other order; (iv) as required in connection with Silicon's examination or audit; and (v) as Silicon considers appropriate in exercising remedies under this Agreement.

Exhibit 10.2 EXPORT-IMPORT BANK LOAN AND SECURITY AGREEMENT THIS EXPORT-IMPORT BANK LOAN AND SECURITY AGREEMENT (this "Exim Agreement") dated as of January 30, 2003, between SILICON VALLEY BANK, a California chartered bank, with its principal place of business at 3003 Tasman Drive, Santa Clara, California 95054 and with a loan production office located at One Newton Executive Park, Suite 200, 2221 Washington Street, Newton, Massachusetts 02462, doing business under the name "Silicon Valley East" ("Bank") and (i) ASPEN TECHNOLOGY, INC., a Delaware corporation with offices at Ten Canal Park, Cambridge, Massachusetts 02141 and (ii) ASPENTECH, INC., a Texas corporation with offices at Ten Canal Park, Cambridge, Massachusetts 02141 (jointly and severally, individually and collectively, "Borrower"), provides the terms on which Bank shall lend to Borrower and Borrower shall repay Bank. The parties agree as follows: SECTION 1. RECITALS. A. Borrower and Bank are parties to that certain Loan and Security Agreement of even date, as may be amended from time to time (as may be amended, the "Domestic Agreement"), together with related documents executed in conjunction therewith. B. Borrower and Bank desire in this Exim Agreement to set forth their agreement with respect to a working capital facility to be guaranteed by the Export-Import Bank of the United States (the "Exim Bank"). SECTION 2. LOAN AND TERMS OF PAYMENT 2.1 PROMISE TO PAY. Borrower hereby unconditionally promises to pay Bank the unpaid principal amount of all Advances and interest on the unpaid principal amount of the Advances as and when due in accordance with this Exim Agreement. 2.2 REVOLVING ADVANCES. Subject to the terms and conditions of this Exim Agreement, Bank agrees to make Advances to Borrower in an amount not to exceed, at any time outstanding, the Exim Committed Line or the Borrowing Base, whichever is less, as determined by the Borrowing Base Certificate to be delivered to the Bank. To evidence the Advances, Borrower shall execute and deliver to Bank on the date hereof a promissory note (the "Note") in substantially the form attached hereto as EXHIBIT B. Whenever Borrower desires an Advance, Borrower will notify Bank by facsimile transmission or telephone no later than 3:00 p.m. Eastern time, on the Business Day that the Advance is to be made together with any additional documentation required under the Borrower Agreement, including without limitation, as set forth in Section 2.03 of the Borrower Agreement. In addition to the procedure set forth in the preceding sentence, Bank is authorized to make Advances under this Exim Agreement, based upon instructions received from a Responsible Officer or without instructions if in Bank's discretion such Advances are necessary to meet Obligations which have become due and remain unpaid. Bank shall be entitled to rely on any telephonic notice given by a person who Bank reasonably believes to be a Responsible Officer or a designee (as designated in writing by a Responsible Officer) thereof, and Borrower shall indemnify and hold Bank harmless for any damages or loss suffered by Bank as a result of such reliance. Bank will credit the amount of Advances made under this Section to Borrower's deposit account. Amounts borrowed pursuant to this Section may be repaid at any time and re-borrowed at any time during the term of this Exim Agreement so long as no Event of Default has occurred and is continuing. 2.3 FOREIGN EXCHANGE. If there is availability under the Exim Committed Line and the Borrowing Base, then Borrower may enter in foreign exchange forward contracts with the Bank under which Borrower commits to purchase from or sell to Bank a set amount of foreign currency more than one business day after the contract date (the "FX Contract"). Bank shall subtract up to 10% of each outstanding FX Contract from the L/C - FX Sublimit (the "FX Reserve"). The total FX Contracts at any one time may not exceed 10 times the amount of the FX Reserve. Bank may terminate the FX Contracts if an Event of Default occurs and is continuing. 1

2.4 LETTERS OF CREDIT. (a) If there is availability under the Exim Committed Line and the Borrowing Base and no Event of Default then exists, Bank shall issue or have issued Commercial Letters of Credit (as defined in the Borrower Agreement) or Standby Letters of Credit (as defined in the Borrower Agreement) for Borrower's account for the purposes set forth in the Borrower Agreement (collectively, the "Letters of Credit"). Each Letter of Credit may have an expiry date later than the Exim Maturity Date provided that Borrower's Letter of Credit reimbursement obligation shall be secured by cash on terms acceptable to Bank (consistent with the procedures set forth in Section 6.2 of the Domestic Agreement) on and after (i) the Exim Maturity Date or (ii) the occurrence and the continuation of an Event of Default hereunder. All Letters of Credit shall be, in form and substance, acceptable to Bank in its sole discretion and shall be subject to the terms and conditions of Bank's form of standard Application and Letter of Credit Agreement. Borrower agrees to execute any further documentation in connection with the Commercial Letters of Credit as Bank may reasonably request. (b) The obligation of Borrower to immediately reimburse Bank for drawings made under Letters of Credit shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Exim Agreement and such Letters of Credit, under all circumstances whatsoever. Borrower shall indemnify, defend, protect, and hold Bank harmless from any loss, cost, expense or liability, including, without limitation, reasonable attorneys' fees, arising out of or in connection with any Letters of Credit, other than those costs, expenses or liabilities directly caused by Bank's gross negligence or willful misconduct. Any payment by Bank under or in connection with a draw on any Letter of Credit shall constitute an Advance hereunder on the date such payment is made. (c) Borrower may request that Bank issue a Letter of Credit payable in a currency other than United States Dollars. If a demand for payment is made under any such Letter of Credit, Bank shall treat such demand as an Advance to Borrower of the equivalent of the amount thereof (plus cable charges) in United States currency at the then prevailing rate of exchange in San Francisco, California, for sales of that other currency for cable transfer to the country of which it is the currency. (d) Upon the issuance of any letter of credit payable in a currency other than United States Dollars, Bank shall create a reserve (the "Letter of Credit Reserve") hereunder for letters of credit against fluctuations in currency exchange rates, in an amount equal to ten percent (10%) of the face amount of such letter of credit. The amount of such reserve may be amended by Bank from time to time to account for fluctuations in the exchange rate as reasonably determined by Bank upon five (5) days' written notice to Borrower. The availability of funds hereunder shall be reduced by the amount of such reserve for so long as such letter of credit remains outstanding. 2.5 L/C - FX SUBLIMIT. Notwithstanding anything to the contrary contained herein, the face amount of outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit and any Letter of Credit Reserve) issued under this Exim Agreement plus the amount of the FX Reserve may not exceed $7,000,000 in the aggregate (the "L/C - FX Sublimit"). In addition, the aggregate amount of FX Reserve hereunder and the FX Reserve (as defined in the Domestic Agreement) under the Domestic Agreement shall not exceed $2,000,000. 2.6 OVERADVANCES. If, at any time or for any reason, the amount of Obligations under this Exim Agreement owed by Borrower to Bank is greater than the lesser of (i) the Borrowing Base or (ii) the Exim Committed Line, the Borrower shall immediately pay to Bank, in cash, the amount of such excess. 2.7 INTEREST RATE; PAYMENTS. (a) INTEREST RATE. Advances accrue interest on the outstanding principal balance at a per annum rate equal to the Prime Rate (as defined herein) plus one-half percent (0.50%). Notwithstanding the foregoing, upon Borrower's achievement of two consecutive quarters of positive net income (as determined by Bank), the interest rate hereunder shall be reduced to the Prime Rate in effect from time to time, plus 2

zero percent (0.0%) per annum. Such reduction in the interest rate shall be effective five (5) business days after Bank receives sufficient (in it reasonable discretion) evidence of such achievement of positive net income. The interest rate applicable to the Obligations shall change on each date there is a change in the Prime Rate. After an Event of Default, Obligations shall bear interest at three percent (3.0%) above the rate effective immediately before the Event of Default. The interest rate shall increase or decrease when the Prime Rate changes. Interest is computed on the basis of a 360 day year for the actual number of days elapsed. (b) PAYMENTS. Interest is payable on the Payment Date of each month. Bank may debit any of Borrower's deposit accounts including Account Number 3300388194 for principal and interest payments or any amounts Borrower owes Bank, including, without limitation, Bank Expenses. Bank shall promptly notify Borrower when it debits Borrower's accounts. These debits are not a set-off. Payments received after 12:00 noon Eastern time are considered received at the opening of business on the next Business Day. When a payment is due on a day that is not a Business Day, the payment is due the next Business Day and additional fees or interest, as applicable, shall continue to accrue. 2.8 FEES. Borrower shall pay to Bank: (i) INITIAL FEE. A fully earned, non-refundable Initial Loan Fee (as defined in, and without duplication of, the Domestic Agreement) due on the date hereof; (ii) SUPPLEMENTAL FEE. A fully earned as of the date hereof, non-refundable Supplemental Loan Fee (as defined in, and without duplication of, the Domestic Agreement) due on January 29, 2004; (iii) LETTER OF CREDIT FEES. Borrower shall pay Bank's customary fees and expenses for the issuance of Letters of Credit; and (iv) BANK EXPENSES. All Bank Expenses (including reasonable attorneys' fees and expenses incurred through and after the date of this Exim Agreement) when due. 2.9 USE OF PROCEEDS. Borrower will use the proceeds of Advances only for the purposes specified in the Borrower Agreement. Borrower shall not use the proceeds of the Advances for any purpose prohibited herein or by the Borrower Agreement. 2.10 TERM. This Exim Agreement shall become effective once duly executed and authorized by Borrower and Bank and shall continue in full force and effect for a term ending on the Exim Maturity Date, on which date all Obligations shall become immediately due and payable. Borrower may terminate this Exim Agreement at any time upon three (3) days prior written notice to Bank and upon full payment and performance of all Obligations outstanding hereunder, including, without limitation, the delivery of cash or cash equivalents as security for any outstanding, but undrawn, Letters of Credit consistent with Section 6.2 of the Domestic Agreement. SECTION 3. CONDITIONS OF LOANS 3.1 CONDITIONS PRECEDENT TO ALL ADVANCES. The obligation of Bank to make each Advance, including the initial Advance, is subject to the following conditions: (a) timely receipt by Bank of a Borrowing Base Certificate as defined in the Borrower Agreement; (b) the Exim Guarantee shall be in full force and effect; and 3

(c) except as otherwise disclosed to the Bank, the representations and warranties contained in Section 5 hereof shall be true and accurate in all material respects on and as of the date of such Advance as though made at and as of each such date (except to the extent they relate specifically to an earlier date, in which case such representations and warranties shall continue to have been true and accurate as of such date), and no potential Event of Default or Event of Default shall have occurred and be continuing, or would result from such Advance. The making of each Advance shall be deemed to be a representation and warranty by Borrower on the date of such Advance as to the accuracy of the facts referred to in this Section 3.1. SECTION 4. CREATION OF SECURITY INTEREST 4.1 GRANT OF SECURITY INTEREST. Borrower hereby grants Bank, to secure the payment and performance in full of all of the Obligations and the performance of each of Borrower's duties under the Loan Documents, a continuing security interest in, and pledges and assigns to the Bank, the Collateral, wherever located, whether now owned or hereafter acquired or arising, and all proceeds and products thereof. Subject to this Section 4.1, the terms of the Domestic Agreement and Permitted Liens, the security interest granted herein shall be a first priority security interest in the Collateral. Notwithstanding the foregoing, it is expressly acknowledged and agreed that the security interest created in this Exim Agreement in all of the Collateral (with the exception of Exim Eligible Foreign Accounts, but only to the extent any Advances are actually made by the Bank to the Borrower based upon such Exim Eligible Foreign Accounts), is subject to and subordinate to the security interest granted to the Bank in the Domestic Agreement with respect to the Collateral. The Collateral may also be subject to Permitted Liens. Bank may, while an Event of Default continues, place a "hold" on any Deposit Account pledged as collateral. Except as described on the Schedule, Borrower is not a party to, nor is bound by, any material license or other material agreement with respect to which the Borrower is the licensee that prohibits or otherwise restricts Borrower from granting a security interest in Borrower's interest in such license or agreement or any other property. Without prior consent from Bank, Borrower shall not enter into, or become bound by, any such license or agreement which is reasonably likely to have a material impact on Borrower's business or financial condition. Borrower shall take such steps as Bank reasonably requests to obtain the consent of, or waiver by, any person whose consent or waiver is necessary for all such licenses or contract rights to be deemed "Collateral" and for Bank to have a security interest in it that might otherwise be restricted or prohibited by law or by the terms of any such license or agreement, whether now existing or entered into in the future. If Borrower shall at any time, acquire a commercial tort claim in excess of $250,000 Borrower shall promptly notify Bank in a writing signed by Borrower of the brief details thereof and grant to Bank in such writing a security interest therein and in the proceeds thereof, all upon the terms of this Exim Agreement, with such writing to be in form and substance reasonably satisfactory to Bank. Borrower agrees that any disposition of the Collateral in violation of this Exim Agreement (unless permitted pursuant to the Domestic Agreement), by either the Borrower or any other Person, shall be deemed to violate the rights of the Bank under the Code. If this Exim Agreement is terminated, Bank's lien and security interest in the Collateral shall continue until Borrower fully satisfies its Obligations. 4.2 RELEASE OF CERTAIN COLLATERAL. If Bank releases certain Collateral from the Domestic Agreement pursuant to Section 2.2 or Section 2.3 thereof, Bank shall also enter into a substantially identical amendment to this Exim Agreement to modify the Collateral granted hereunder consistent with Section 2.2 and Section 2.3 of the Domestic Agreement. SECTION 5. REPRESENTATIONS AND WARRANTIES Borrower represents, warrants and covenants as follows: 5.1 DOMESTIC LOAN DOCUMENTS. The representations and warranties contained in the Domestic Loan Documents, which are incorporated by reference into this Exim Agreement, are true and correct. 4

SECTION 6. AFFIRMATIVE COVENANTS Borrower covenants and agrees that, until payment in full of all Obligations, it shall do all of the following: 6.1 DOMESTIC LOAN DOCUMENTS.

Unless otherwise waived in writing by Exim Bank, Borrower shall comply with all of the terms of the Borrower Agreement, including without limitation, the delivery of any and all notices required pursuant to Sections 2.11 and/or 2.18 of the Borrower Agreement. In the event of any conflict or inconsistency between any provision contained in the Borrower Agreement with any provision contained in this Exim Agreement, the more strict provision, with respect to Borrower, shall control. 6.3 NOTICE IN EVENT OF FILING OF ACTION FOR DEBTOR'S RELIEF. Borrower shall notify Bank in writing within five (5) days of the occurrence of any of the following: (1) Borrower begins or consents in any manner to any proceeding or arrangement for its liquidation in whole or in part or to any other proceeding or arrangement whereby any of its assets are subject generally to the payment of its liabilities or whereby any receiver, trustee, liquidator or the like is appointed for it or any substantial part of its assets (including without limitation the filing by Borrower of a petition for appointment as debtor-in-possession under Title 11 of the U.S. Code); (2) Borrower fails to obtain the dismissal or stay on appeal within forty-five (45) calendar days of the commencement of any proceeding arrangement referred to in (1) above; (3) Borrower begins any other procedure for the relief of insolvent debtors, or such procedure has been commenced against it, whether voluntarily or involuntarily, and such procedure has not been effectively terminated, dismissed or stayed within thirty (30) calendar days after the commencement thereof, or (4) Borrower begins any procedure for its dissolution, or a procedure therefor has been commenced against it. 6.4 CURRENCY. Borrower shall require payment in United States Dollars or an Accpetable Foreign Currency for the products, unless the Exim Bank otherwise agrees in writing hereafter. 6.5 FURTHER ASSURANCES. At any time and from time to time Borrower shall (i) execute and deliver such further instruments, (ii) take such further action as may reasonably be requested by Bank, and (iii) deliver such additional information, reports, contracts, invoices and other data concerning the Collateral in each case as may reasonably be requested by Bank, all of the foregoing in furtherance of the purposes of this Exim Agreement. SECTION 7. NEGATIVE COVENANTS Prior to the (i) payment in full of outstanding Obligations, and (ii) termination of Bank's commitment to make any Advance, Borrower shall not do any of the following without the Bank's written consent: 7.1 DOMESTIC LOAN DOCUMENTS. Violate or otherwise fail to comply with any provisions of the Domestic Loan Documents, which provisions are incorporated into this Exim Agreement. 7.2 BORROWER AGREEMENT. Violate or otherwise fail to comply with any provision of the Borrower Agreement, including without limitation the negative covenants set forth in Section 2.15. 7.3 EXIM GUARANTEE. Take any action, or permit any action to be taken, that causes or, with the passage of time, could reasonably be expected to cause, the Exim Guarantee to cease to be in full force and effect. 5

SECTION 8. EVENTS OF DEFAULT Any one of the following is an Event of Default: 8.1 PAYMENT DEFAULT. If Borrower fails to pay when due, any of the monetary Obligations. 8.2 COVENANT DEFAULT; CROSS DEFAULT. If Borrower fails or neglects to perform, keep, or observe(i) any material non-monetary Obligations, term, provision, condition, covenant, or agreement contained in this Exim Agreement or the Borrower Agreement, which failure is not cured within twenty (20) Business Days after the earlier of (x) Borrower's knowledge of same or (y) Bank's notice to Borrower, or (ii) an Event of Default occurs under any of the Domestic Loan Documents past any applicable cure periods, which terms and provisions are incorporated into this Exim Agreement and shall survive the termination of the Domestic Agreement; or 8.3 EXIM GUARANTEE. If the Exim Guarantee ceases for any reason to be in full force and effect, or if the Exim Bank declares the Exim Guarantee void or revokes or purports to revoke any obligations under the Exim Guarantee. SECTION 9. BANK'S RIGHTS AND REMEDIES 9.1 RIGHTS AND REMEDIES. When an Event of Default occurs and continues beyond any applicable notice and cure period, Bank may, without notice or demand, do any or all of the following: (a) Declare all Obligations immediately due and payable (but if an Event of Default described in Section 7.1(i) of the Domestic Agreement occurs all Obligations are immediately due and payable without any action by Bank); (b) Stop advancing money or extending credit for Borrower's benefit under this Exim Agreement or under any other agreement between Borrower and Bank; (c) Settle or adjust disputes and claims directly with account debtors for amounts, on terms and in any order that Bank considers advisable; (d) Make any payments and do any acts it considers necessary or reasonable to protect its security interest in the Collateral. Borrower shall assemble the Collateral if Bank requests and make it available as Bank designates. Bank may, in accordance with applicable law and in a commercially reasonable manner, enter premises where the Collateral is located, take and maintain possession of any part of the Collateral, and pay, purchase, contest, or compromise any Lien which appears to be prior or superior to its security interest and pay all expenses incurred. Borrower grants Bank a license to enter and occupy any of its premises, without charge, to exercise any of Bank's rights or remedies; (e) Apply to the Obligations any (i) balances and deposits of Borrower it holds, or (ii) any amount held by Bank owing to or for the credit or the account of Borrower; (f) Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell the Collateral. (g) Dispose of the Collateral according to the Code. 9.2 EXIM DIRECTION. Upon the occurrence and during the continuance of an Event of Default, Exim Bank shall have a right to: (i) direct Bank to exercise the remedies specified in Section 9.1 and (ii) request that Bank accelerate the maturity of any other loans to Borrower as to which Bank has a right to accelerate. 9.3 EXIM NOTIFICATION. Bank shall have the right to immediately notify Exim Bank in writing if it has knowledge of the occurrence of any of the following events: (1) any failure to pay any amount due under this Exim Agreement or the Note; (2) the Borrowing Base is less than the sum of outstanding Advances hereunder; (3) any failure to pay when due any amount payable to Bank by the Borrower under any loan(s) extended by Bank to Borrower; (4) the filing of an action for debtor's relief by, against, or on behalf of Borrower; or (5) any threatened or pending material litigation against Borrower, or any material dispute involving Borrower. 6

In the event that it sends such a notification to Exim Bank, Bank shall have the right to thereafter send Exim Bank a written report on the status of the events covered by said notification on each Business Day which occurs every thirty (30) calendar days after the date of said notification, until such time as Bank files a claim with Exim Bank or said default or other events have been cured. Bank shall not have any obligation to make any Advances following said notification to Exim Bank, unless Exim Bank gives its written approval thereto. If directed to do so by Exim Bank, Bank shall have a right promptly to exercise any rights it may have against Borrower to demand the immediate repayment of all amounts outstanding under the Exim Loan Documents. 9.4 REMEDIES CUMULATIVE. Bank's rights and remedies under this Exim Agreement, the Exim Loan Documents, the Domestic Loan Documents and all other agreements shall be cumulative. Bank shall have all other rights and remedies not inconsistent herewith as provided under the Code, by law, or in equity. No exercise by Bank of one right or remedy shall be deemed an election, and no waiver by Bank of any Event of Default on Borrower's part shall be deemed a continuing waiver. No delay by Bank shall constitute a waiver, election, or acquiescence by it. No waiver by Bank shall be effective unless made in a written document signed on behalf of Bank and then shall be effective only in the specific instance and for the specific purpose for which it was given. 9.5 POWER OF ATTORNEY. Borrower hereby irrevocably appoints Bank as its lawful attorney-in-fact, to be effective upon the occurrence and during the continuance of an Event of Default, to: (i) endorse Borrower's name on any checks or other forms of payment or security; (ii) sign Borrower's name on any invoice or bill of lading for any Account or drafts against account debtors; (iii) settle and adjust disputes and claims about the Accounts directly with account debtors, for amounts and on terms Bank determines reasonable; (iv) make, settle, and adjust all claims under Borrower's insurance policies; and (v) transfer the Collateral into the name of Bank or a third party as the Code permits. Borrower hereby appoints Bank its power of attorney to sign Borrower's name on any documents necessary to perfect or continue the perfection of any security interest regardless of whether an Event of Default has occurred until all Obligations have been satisfied in full and Bank is under no further obligation to make Advances hereunder. Bank's foregoing appointment as Borrower's attorney in fact, and all of Bank's rights and powers, coupled with an interest, are irrevocable until all Obligations have been fully repaid and performed and Bank's obligation to provide Advances terminates. 9.6 ACCOUNTS COLLECTION. In the event that an Event of Default occurs and is continuing, Bank may notify any Person owing Borrower money of Bank's security interest in the funds and verify and/or collect the amount of the Account. Any amounts received by Borrower shall be held in trust by Borrower for Bank, and, if requested by Bank, Borrower shall immediately deliver such receipts to Bank in the form received from the account debtor, with proper endorsements for deposit. 9.7 BANK EXPENSES. Any amounts paid by Bank as provided herein are Bank Expenses and are immediately due and payable, and shall bear interest at the then applicable rate and be secured by the Collateral. No payments by Bank shall be deemed an agreement to make similar payments in the future or Bank's waiver of any Event of Default. 9.8 BANK'S LIABILITY FOR COLLATERAL. So long as the Bank complies with reasonable banking practices regarding the safekeeping of collateral, the Bank shall not be liable or responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral; (c) any diminution in the value of the Collateral; or (d) any act or default of any carrier, warehouseman, bailee, or other person. Subject to the foregoing, Borrower bears all risk of loss, damage or destruction of the Collateral. 9.9 DEMAND WAIVER. Borrower waives demand, notice of default or dishonor, notice of payment and nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees held by Bank on which Borrower is liable. 7

NOTICES Unless otherwise provided in this Exim Agreement, all notices or demands by any party relating to this Exim Agreement or any other agreement entered into in connection herewith shall be in writing and (except for financial statements and other informational documents which may be sent by first-class mail, postage prepaid) shall be personally delivered or sent by a recognized overnight delivery service, by certified mail, postage prepaid, return receipt requested, or by telefacsimile to Borrower or to Bank, as the case may be, at the address set forth in the Domestic Loan Documents. The parties hereto may change the address at which they are to receive notices hereunder, by notice in writing in the foregoing manner given to the other. SECTION 11. CHOICE OF LAW, VENUE AND JURY TRIAL WAIVER Massachusetts law governs the Loan Documents without regard to principles of conflicts of law. Borrower and Bank each submit to the non-exclusive jurisdiction of the State and Federal courts in Massachusetts; provided, however, that if for any reason Bank cannot avail itself of such courts in the Commonwealth of Massachusetts, Borrower accepts jurisdiction of the courts and venue in Santa Clara County, California. BORROWER AND BANK EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS EXIM AGREEMENT, THE LOAN DOCUMENTS OR ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS EXIM AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL. SECTION 12.

Borrower hereby indemnifies, defends and holds the Bank and its officers, employees and agents harmless against: (a) all obligations, demands, claims, and liabilities asserted by any other party in connection with the transactions contemplated by the Loan Documents; and (b) all losses or Bank Expenses incurred, or paid by Bank from, following, or consequential to transactions between Bank and Borrower (including reasonable attorneys' fees and expenses), except for losses caused by Bank's gross negligence or willful misconduct. 12.3 RIGHT OF SET-OFF. Borrower and any guarantor hereby grant to Bank, a lien, security interest and right of setoff as security for all Obligations to Bank, whether now existing or hereafter arising upon and against all deposits, credits, collateral and property, now or hereafter in the possession, custody, safekeeping or control of Bank or any entity under the control of the Bank or in transit to any of them. At any time after the occurrence and during the continuance of an Event of Default, without demand or notice, Bank may set off the same or any part thereof and apply the same to any liability or obligation of Borrower and any guarantor even though unmatured and regardless of the adequacy of any other collateral securing the loan. ANY AND ALL RIGHTS TO REQUIRE BANK TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURES THE LOAN, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF THE BORROWER OR ANY GUARANTOR, ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED. 12.4 TIME OF ESSENCE.

RECITALS Debtor has executed and delivered a certain instrument of Unconditional Guaranty to Bank of even date herewith (as may be amended from time to time, the "Guaranty"), pursuant to which the Debtor unconditionally guarantied the payment and performance of the obligations and liabilities (hereinafter, the "Liabilities") of ASPEN TECHNOLOGY, INC., a Delaware corporation, ASPENTECH, INC., a Texas corporation and HYPROTECH COMPANY, a company organized under the laws of Nova Scotia, Canada (collectively, "Borrower") to Bank (as may be amended from time to time, the "Guaranty"). Bank has agreed to lend money to Borrower, but only upon the condition that Debtor execute and deliver this Security Agreement to secure the payment and performance of the Guaranty. Capitalized terms used but not otherwise defined herein shall have the same meaning as in the Loan and Security Agreement by and between the Bank and Borrower of even date herewith, as amended from time to time (the "Loan Agreement") AGREEMENT The parties agree as follows: 1. CREATION OF SECURITY INTEREST 1.1 GRANT OF SECURITY INTEREST. Debtor grants to Bank a security interest in the property described in EXHIBIT A attached hereto (the "Collateral") to secure the Guaranty, and any and all liabilities and obligations of Debtor to Bank under the Guaranty and any other agreements entered into between Debtor and Bank in connection therewith (the "Loan Documents"). Such security interest constitutes a first priority security interest in the presently existing Collateral subject to Permitted Liens, and will constitute a first priority security interest in Collateral acquired after the date hereof subject to Permitted Liens. 1.2 FINANCING STATEMENTS. This Agreement constitutes an authenticated record which authorizes the Bank to file such financing statements as Bank reasonably determines appropriate. Without limiting the generality of the foregoing, Debtor hereby expressly authorizes Bank to file financing statements without notice to Debtor, with all appropriate jurisdictions, as Bank in its reasonable discretion deems appropriate from time to time, in order to further perfect, protect, or vest more securely Bank's interest in the Collateral. 1.3 DELIVERY OF ADDITIONAL DOCUMENTATION REQUIRED. Debtor shall from time to time execute and deliver to Bank, at the request of Bank, all financing statements and other documents that Bank may reasonably request, in form satisfactory to Bank, to perfect and continue perfected Bank's security interests in the Collateral and in order to fully consummate all of the transactions contemplated under the Loan Documents. 2. REPRESENTATIONS AND WARRANTIES Debtor represents and warrants as follows: 1

The execution, delivery, and performance of this Agreement are within Debtor's powers, have been duly authorized, and are not in conflict with nor constitute a breach of any provision contained in Debtor's organizational documents, nor will they constitute an event of default under any material agreement to which Debtor is a party or by which Debtor is bound. 2.3 NO PRIOR ENCUMBRANCES. Debtor has good and indefeasible title to the Collateral, free and clear of any liens, security interests, or other encumbrances (other than the Permitted Liens). 3.

Debtor shall also maintain insurance relating to Debtor's ownership and use of the Collateral in amounts and of a type that are customary to businesses similar to Debtor's. (b) All such policies of insurance shall be in such form, with such companies, and in such amounts as reasonably satisfactory to Bank. All such policies of property insurance shall contain a lender's loss payable endorsement, in a form satisfactory to Bank, showing Bank as an additional loss payee thereof and all liability insurance policies shall show the Bank as an additional insured, and shall specify that the insurer must give at least twenty (20) days notice to Bank before canceling its policy for any reason. 2

Debtor assumes the responsibility for being and keeping itself informed of the financial condition of Borrower and of all other circumstances bearing upon the risk of nonpayment of any indebtedness or nonperformance of any obligation of Borrower, warrants to Bank that it will keep so informed, and agrees that absent a request for particular information by Debtor, Bank shall have no duty to advise Debtor of information known to Bank regarding such condition or any such circumstances. 8.10 INSOLVENCY. If Borrower becomes insolvent or is adjudicated bankrupt or files a petition for reorganization, arrangement, composition or similar relief under any present or future provision of the United States Bankruptcy Code, or if such a petition is filed against Borrower, and in any such proceeding some or all of any indebtedness or obligations under the Loan Documents are terminated or rejected or any obligation of Borrower is modified or abrogated, or if Borrower's obligations are otherwise avoided for insolvency, bankruptcy or any similar reason, Debtor agrees that Debtor's liability hereunder shall not thereby be affected or modified and such liability shall continue in full force and effect as if no such action or proceeding had occurred. This Agreement shall continue to be effective or be reinstated, as the case may be, if any payment must be returned by Bank upon the insolvency, bankruptcy or reorganization of Borrower or Debtor, any other person, or otherwise, as though such payment had not been made. 7

Exhibit 10.7 UNCONDITIONAL GUARANTY For and in consideration of certain loans by SILICON VALLEY BANK, a California-chartered bank, with its principal place of business at 3003 Tasman Drive, Santa Clara, California 95054 and with a loan production office located at One Newton Executive Park, Suite 200, 2221 Washington Street, Newton, Massachusetts 02462, doing business under the name "Silicon Valley East" ("Bank") to ASPEN TECHNOLOGY, INC., a Delaware corporation, ASPENTECH, INC., a Texas corporation and HYPROTECH COMPANY, a company organized under the laws of Nova Scotia, Canada (collectively, "Borrower") , which loans were made pursuant to a certain Loan and Security Agreement and Export-Import Loan and Security Agreement between Borrower and Bank dated each of even date herewith as each may be amended from time to time (hereinafter, collectively, the "Agreement"), the undersigned guarantor, ASPENTECH SECURITIES CORP., a Massachusetts corporation with its chief executive office located at Ten Canal Park, Cambridge, Massachusetts 02141 ("Guarantor"), hereby unconditionally and irrevocably guarantees the prompt and complete payment of all amounts that Borrower owes to Bank and performance by Borrower of the Agreement and any other agreements now existing or hereafter arising between Borrower and Bank, as each may be amended from time to time (collectively referred to as the "Agreements"), in strict accordance with their respective terms. 1. If Borrower does not perform its obligations under the Agreements, Guarantor will, upon demand by Bank, immediately pay all amounts due (including, without limitation, all principal, interest, and fees) and satisfy all Borrower's obligations under the Agreements. 2. These obligations are independent of Borrower's obligations and separate actions that may be brought against Guarantor (whether action is brought against Borrower or whether Borrower is joined in the action). Guarantor's liability is not contingent on the genuineness or enforceability of the Agreements. 3. Bank may, without notice to Guarantor and without affecting Guarantor's obligations under this Guaranty: (a) renew, extend, or otherwise change the terms of the Agreements; (b) take security for the payment of this Guaranty or the Agreements; (c) exchange, enforce, waive and release any security; and (d) apply the security and direct its sale as Bank, in its reasonable discretion, chooses. 4. Until all obligations and liabilities of Borrower to Bank have been paid in full and the Agreements have been terminated, Guarantor waives to the extent permitted by law: (a) Any right to require Bank to: (i) proceed against Borrower or any other person; (ii) proceed against or exhaust any security; or (iii) pursue any other remedy. Bank may exercise or not exercise any right or remedy it has against Borrower or any security it holds (including the right to foreclose by judicial or non-judicial sale) without affecting Guarantor's liability. (b) Any defenses from disability or other defense of Borrower or from the cessation of Borrowers liabilities. (c) Any right of setoff or right to counterclaim against Bank. (d) Any defense from the absence, impairment or loss of any right of reimbursement or subrogation or any other rights against Borrower. Until Borrower's obligations to Bank have been paid, Guarantor has no right of subrogation or reimbursement or subrogation or other rights against Borrower. (e) Any right to enforce any remedy that Bank has against Borrower. (f) Any rights to participate in any security held by Bank. (g) Any demands for performance, notices of nonperformance or of new or additional indebtedness. Guarantor is responsible for being and keeping itself informed of Borrower's financial 1

condition. Unless Guarantor requests particular information, Bank has no duty to provide information to Guarantor. 5. Guarantor acknowledges that, to the extent Guarantor has or may have rights of subrogation or reimbursement against Borrower for claims arising out of this Guaranty, those rights may be impaired or destroyed if Bank elects to proceed against any real property security of Borrower by non-judicial foreclosure. That impairment or destruction could, under certain judicial cases and based on equitable principles of estoppel, give rise to a defense by Guarantor against its obligations under this Guaranty. Guarantor waives that defense and any others arising from Bank's election to pursue non-judicial foreclosure. 6. If Borrower becomes insolvent or is adjudicated bankrupt or files a petition for reorganization or similar relief under the United States Bankruptcy Code, or if a petition is filed against Borrower and/or any obligation under the Agreements is terminated or rejected, or any obligation of Borrower is modified or if Borrower's obligations are avoided Guarantor's liability will not be affected and its liability will continue. If Bank must return any payment because of the insolvency, bankruptcy or reorganization of Borrower, Guarantor or any other guarantor, this Guaranty will remain effective or be reinstated. 7. Guarantor subordinates any indebtedness of Borrower it holds to Bank; and Guarantor will collect, enforce and, upon the occurrence of an Event of Default, receive payments as Bank's trustee and will pay Bank those payments without reducing or affecting its liability under this Guaranty. 8. Guarantor will pay Bank's reasonable attorneys' fees and other costs and expenses incurred enforcing this Guaranty. This Guaranty may not be waived, revoked or amended without Bank's prior written consent. If any provision of this Guaranty is unenforceable, all other provisions remain effective. This Guaranty represents the entire agreement among the parties about this guaranty. No prior dealings, no usage of trade, and no parol or extrinsic evidence may supplement or vary this Guaranty. Bank may assign this Guaranty. This Guaranty benefits Bank, its successors and assigns. This Guaranty is in addition to any other guaranties Bank obtains. 9. Guarantor represents and warrants that (i) it has taken all action necessary to authorize execute, deliver and perform this Guaranty; (ii) execution, delivery and performance of this Guaranty do not conflict with any organizational documents or agreements to which it is a party; and (iii) this Guaranty is a valid and binding obligation, enforceable against Guarantor according to its terms. 10. Guarantor will do all of the following: (a) Maintain its corporate existence, remain in good standing in Massachusetts, and continue to qualify in each jurisdiction in which the failure to qualify could reasonably be expected to have a material adverse effect on the financial condition, operations or business. Maintain all licenses, approvals, and agreements, the loss of which could reasonably be expected to have a material adverse effect on its financial condition, operations or business. (b) Comply with all statutes and regulations if non-compliance could reasonably be expected to adversely and materially affect its financial condition, operations or business. (c) Execute other instruments and take action Bank reasonably requests to effect the purposes of this Agreement. 11. Guarantor hereby grants to Bank, a lien, security interest and right of setoff as security for all obligations to Bank, whether now existing or hereafter arising upon and against all deposits, credits, collateral and property, now or hereafter in the possession, custody, safekeeping or control of Bank or any entity under the control of Bank (including a Bank subsidiary) or in transit to any of them. At any time after the occurrence and during the continuance of an Event of Default (as defined in the Agreement), without demand or notice, Bank may set off the same or any part thereof and apply the same to any liability or obligation of Guarantor even though unmatured and regardless of the adequacy of any other collateral securing the loan. ANY AND ALL RIGHTS TO REQUIRE 2

BANK TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURES THE LOAN, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF THE GUARANTOR, ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED. 12. Massachusetts law governs this Guaranty without regard to principles of conflicts of law. Guarantor and Bank each submit to the exclusive jurisdiction of the State and Federal courts in Massachusetts; provided, however, that if for any reason Bank cannot avail itself of such courts in the Commonwealth of Massachusetts, Guarantor accepts jurisdiction of the courts and venue in Santa Clara County, California. NOTWITHSTANDING THE FOREGOING, THE BANK SHALL HAVE THE RIGHT TO BRING ANY ACTION OR PROCEEDING AGAINST THE GUARANTOR OR ITS PROPERTY IN THE COURTS OF ANY OTHER JURISDICTION WHICH THE BANK REASONABLY DEEMS NECESSARY OR APPROPRIATE IN ORDER TO REALIZE ON THE COLLATERAL OR TO OTHERWISE ENFORCE THE BANK'S RIGHTS AGAINST THE GUARANTOR OR ITS PROPERTY. GUARANTOR AND BANK EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE LOAN DOCUMENTS OR ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL. 3

To secure the prompt payment of the Outstanding Debt, AspenTech hereby grants to Accenture a lien and first priority security interest in AspenTech's right, title and interest in and to the installment receivables or other rights to receive payment listed on SCHEDULE 1 attached hereto together with the proceeds therefrom (the "Installment Collateral"). The Parties agree that the security interest in the Installment Collateral granted hereby replaces and supercedes Accenture's security interest in the collateral set forth on EXHIBIT A of the original Agreement (the "Original Collateral") and any other security interest to which Accenture otherwise would have been entitled pursuant to the terms of the original Agreement.

2. AspenTech represents and warrants to Accenture that (i) AspenTech is the legal and beneficial owner of the Installment Collateral free and clear of all liens, security interests or other encumbrances, (ii) there is no dispute, right of setoff, counterclaim or defense exists with respect to all or any part of the Installment Collateral, and (iii) this Agreement creates a valid security interest in the Installment Collateral, securing the payment of the Outstanding Debt. 3. AspenTech will collect, in the ordinary course of business, at its own expense, all amounts due or to become due under each of the Installment Collateral. In the event that AspenTech fails to repay the Outstanding Debt in accordance with the schedule set forth in the License Fee Agreement, as amended, then all proceeds collected with respect to the Installment Collateral shall be paid to Accenture to satisfy the portion of the Outstanding Debt then due. 4. After February 1, 2003, in the event that the aggregate amounts outstanding and owed to AspenTech pursuant to the Installment Collateral is less than an amount equal to twice the amount of the Outstanding Debt, AspenTech shall grant to Accenture, on a first priority basis, a lien and security interest in additional installment receivables (the "Additional Collateral") in such amounts so that the aggregate amounts outstanding and owed to AspenTech pursuant to the Installment Collateral and such Additional Collateral are equal to an amount equal to twice the Outstanding Debt. AspenTech and Accenture shall mutually agree on those certain installment receivables that shall constitute Additional Collateral upon which AspenTech will grant a lien and security interest to Accenture. 5. Notwithstanding anything in this Agreement to the contrary, AspenTech expressly agrees that it shall remain liable under each of the contracts and agreements in the Installment Collateral and that it shall perform, in all material respects, all of its duties and obligations thereunder, all in accordance with and pursuant to the terms and provisions of each such contract or agreement. Accenture shall not have any obligation or liability under any contract or agreement in the Installment Collateral by reason of or arising out of this Agreement or the granting to Accenture of a lien therein or the receipt by Accenture of any payment relating to the Installment Collateral. 6. Accenture hereby releases its security interest in the Original Collateral and authorizes AspenTech's filing of Uniform Commercial Code ("UCC") termination statements to evidence such termination and release of its security interest in the Original Collateral. 7. Accenture agrees that it shall from time to time, upon reasonable request by AspenTech, (a) release its security interest in that portion of

the Installment Collateral and Additional Collateral that is in excess of twice the amount of the Outstanding Debt and (b) authorize AspenTech to file UCC termination statements to evidence such termination and release of Accenture's security interest in such excess portion of the Installment Collateral and Additional Collateral. 8. For so long as the Outstanding Debt remains outstanding, Accenture shall have the right, upon default by AspenTech of any of the material provisions of the Amended Agreements and the continuance of such default, to enforce the provisions of this Agreement and exercise remedies hereunder in such a manner as it may determine reasonable, including, without limitation, the rights to take possession, sell or otherwise dispose of the Installment Collateral or Additional Collateral, to incur other expenses with respect to such possession, sale or disposition and to exercise all rights and remedies as a secured lender under the Uniform Commercial Code of any applicable jurisdiction. 9. From time to time, upon the reasonable request of Accenture, AspenTech shall promptly execute and deliver any and all such further instruments and documents and take such further action as Accenture may reasonably deem necessary or desirable to obtain the full benefits of this Agreement, including, without limitation, facilitating the filing of UCC-1 Financing Statements in all applicable jurisdictions. 10. This Agreement shall terminate upon the full and final payment of the Outstanding Debt in accordance with the terms set forth in the License Fee Agreement, as amended. 11. No failure on the part of any of Accenture to exercise, and no delay in exercising any right hereunder, shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. The wavier by Accenture of any breach of any provision of this Agreement or warranty or representation herein set forth will not be construed as a waiver of any subsequent breach. The failure to exercise any right hereunder by Accenture will not operate as a waiver of such right. All rights and remedies herein provided are cumulative. This Agreement may not be altered or amended except by a writing signed by all the parties hereto. This Agreement binds AspenTech, its successors and assigns, and inures to the benefit of Accenture, its successors and assigns." 2. AspenTech acknowledges and confirms that it shall pay to Accenture on February 1, 2003 the amounts which would otherwise be due to Accenture on February 28, 2003 pursuant to the terms of the License Fee Agreement, as amended. AspenTech further acknowledges and confirms that, prior to April 1, 2003, it shall pay to Accenture all amounts due on or before March 31, 2003 pursuant to the Amended Agreements. 3. This Amendment No.1 may be executed in counterparts, each of which so executed shall be deemed an original and both of which taken together shall constitute one and the same Agreement. In the event that a signature is executed and delivered by facsimile transmission, such signature shall create a binding obligation of the party on whose behalf such signature is executed with the same force and effect as if such facsimile signature were the original thereof. IN WITNESS WHEREOF, the undersigned have each executed this Amendment No. 1 as of the date first set forth above. ACCENTURE LLP ASPEN TECHNOLOGY, INC. By: /s/ David A. Crow By: /s/ Lisa W.

Exhibit 10.9 EMPLOYMENT AGREEMENT THIS EMPLOYMENT AGREEMENT dated as of November 26, 2002 (this "Agreement") is entered into between Aspen Technology, Inc., a Delaware corporation ("Aspen") and David L. McQuillin (the "Employee"). 1. BASIS FOR AGREEMENT This agreement replaces the letter of September 30, 2002, and further supplements the existing terms of employment between Aspen and the Employee, including the Change in Control Agreement dated August 12, 1997 ("Change in Control Agreement"), which remains in full force and effect. Aspen is continuing to employ the Employee as a key employee of Aspen and has determined that Employee's services are essential to the successful operation and future of Aspen. Employee currently holds the position of President and Chief Executive Officer. Aspen has determined that it is in its best interests to secure certain employment commitments from Employee in consideration of providing certain severance and compensation commitments to Employee. 2. COMPENSATION Employee's compensation will be as agreed to by the Compensation Committee of the Board of Directors. 3. TERMINATION: NOTICE AND SEVERANCE (a) Upon termination of employment for any reason other than death, resignation without Good Reason, or for Cause, Aspen shall, in addition to any benefits due under written plans, pay you your base salary for 18 months after termination of employment. (b) "For Cause," means (A) a good faith finding by Aspen that the Employee has failed to perform his reasonably assigned duties for Aspen and has failed to remedy such failure within 30 days following written notice from Aspen to the Employee notifying him of such failure, (B) a good faith finding by the Board of Directors of Aspen that the Employee has engaged in dishonesty, gross negligence or misconduct, or (C) the conviction of the Employee of, or the entry of a pleading of guilty or NOLO CONTENDERE by the Employee to, any felony; or (c) "Good Reason" means termination by the Employee of the Employee's employment upon the occurrence (without the Employee's express written consent) of any one of the following acts or failures to act by Aspen unless, in the case of any act or failure to act described in paragraph (i), (v), or (vi) below, such act or failure to act is corrected prior to the date of termination specified in the notice of termination given in respect thereof or, in the case of paragraph (iii) below, such act is not objected to in writing by the Employee within four months after notification by Aspen to Employee of Aspen's intention to take the action contemplated by such paragraph (iii):

(i) the assignment to the Employee of any duties inconsistent with the Employee's status as a senior Employee officer of Aspen or a meaningful alteration, adverse to the Employee, in the nature or status of the Employee's responsibilities (other than reporting responsibilities) from those in effect; (ii) a reduction by Aspen in the Employee's annual base salary as in effect on the date hereof or as the same may be increased from time to time except for across-the-board salary reductions similarly affecting all senior Employees of Aspen and all senior Employees of any Person in control of Aspen; (iii) Aspen's requiring Employee to be based anywhere other than the Boston Metropolitan Area except for required travel on Aspen business to an extent substantially consistent with Employee's present business travel obligations; (iv) the failure by Aspen, without the Employee's consent, to pay to the Employee any portion of the Employee's current compensation, or to pay to the Employee any portion of an installment of deferred compensation under any deferred compensation program of Aspen, within fourteen days of the date such compensation is due; (v) the failure by Aspen to continue in effect any compensation plan in which the Employee participates which is material to the Employee's total compensation, or the failure by Aspen to continue the Employee's participation therein on a basis not materially less favorable, both in terms of the amount of benefits provided and the level of the Employee's participation relative to other participants; (vi) the failure by Aspen to continue to provide Employee with benefits substantially similar to those enjoyed by Employee under any of Aspen' s pension, life insurance, medical, health and accident, or disability plans in which Employee is at any time participating, the taking of any action by Aspen which would directly or indirectly materially reduce any of such benefits or deprive Employee of any material fringe benefit enjoyed by Employee, or the failure by Aspen to provide Employee with the number of paid vacation days to which the Employee is entitled on the basis of years of service with Aspen in accordance with Aspen's normal vacation policy. 4. APPLICATION OF CHANGE IN CONTROL AGREEMENT Notwithstanding anything to the contrary herein, this Agreement shall not apply in the event that Employee's Change in Control Agreement is deemed to be valid, enforceable, and -2-

applicable, and further that Employee receives the compensation provided for thereunder equal to or in excess of the amount provided for under this Agreement. 5. MISCELLANEOUS (a) AMENDMENTS AND WAIVERS. No amendment of any provision of this Agreement shall be valid unless the same shall be in writing and signed by both of the parties hereto. No waiver of any right or remedy hereunder shall be valid unless the same shall be in writing and signed by the party giving such waiver. No waiver by either party hereto with respect to any condition or breach hereunder shall be deemed to extend to any prior or subsequent condition or breach hereunder or affect in any way any rights arising by virtue of any prior or subsequent condition or breach. No failure on the part of any party hereto to exercise, and no delay in exercising any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. (b) CONSTRUCTION. (i) The section headings contained in this Agreement are inserted for convenience only and shall not affect in any way the meaning or interpretation of this Agreement. (ii) The language used in this Agreement shall be deemed to be the language chosen by the parties hereto to express their mutual intent, and no rule of strict construction shall be applied against a party hereto. (iii) The term "including" as used herein shall not be construed so as to exclude any other thing not referred to or described. (iv) References herein to "Sections" shall be deemed to be to sections of this Agreement, unless otherwise specified. (c) ENTIRE AGREEMENT; SUCCESSORS. This Agreement, including the exhibits hereto, (i) constitutes the entire agreement, and supersedes all other prior agreements and understandings, both written and oral, between the parties with respect to the subject matter hereof and (ii) is not intended to confer upon any person other than the parties hereto any rights or remedies hereunder, except as otherwise expressly provided herein. For purposes of clarification, this Agreement does not replace or otherwise amend your Change in Control Agreement dated August 12, 1997, which remains in full force and effect. In the event of a termination that qualifies you for compensation under both agreements, then the terms of the Change in Control Agreement shall control. (d) The obligations of Aspen may be assigned by Aspen, provided that such obligations shall be assumed by such subsidiary without modification. For all purposes of this Agreement, the term "Aspen" shall include any successor to the business of Aspen (whether direct or indirect and whether by merger, consolidation, sale of assets or otherwise). -3-

(e) GOVERNING LAW. This Agreement shall be governed by and construed in accordance with the internal laws of the Commonwealth of Massachusetts without giving effect to any choice or conflict of law provision or rule (whether of the Commonwealth of Massachusetts) or any other jurisdiction) that would cause the application of laws of any jurisdictions other than those of the Commonwealth of Massachusetts. (f) NOTICES. All notices, instructions, demands, claims, requests and other communications given hereunder or in connection herewith shall be in writing. Any such communication shall be sent either (a) by registered or certified mail, return receipt requested, postage prepaid, or (b) via a reputable nationwide overnight courier service, in each case to the address set forth below.

Either party hereto may change the address to which notices, instructions, demands, claims, requests and other communications hereunder are to be delivered by giving the other party hereto notice in the manner set forth in this Section. (g) SEVERABILITY. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the parties hereto agree that the court making the determination of invalidity or unenforceability shall have the power to limit the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified. -4-
